The Britannica Concise Encyclopedia  satisfies the essence of both these needs.  This volume represents the distillation of  essential information into a compact and eminently  useful single volume.</p><p>This latest version of Britannica Concise Encyclopedia  answers today's need for a portable, convenient ref�  erence work covering history, geography, the sci�  ences, religion, sports, entertainment, technology,  and the arts. We hope it will become a favourite  source for helping students with their homework,  for background to news events, for writers and  crossword-puzzle enthusiasts, for solving disputes,  and for random browsing.</p><p>This printing of Britannica Concise Encyclopedia has  been broadly revised. Among the 2.8 million words  that make up the nearly 28,000 entries are many  new titles and many that have been updated. In the  16-page colour plates section, you will find the</p><p>newest versions of national flags as well as a  world map, maps of world religions and popula�  tion characteristics, a selection of World Heritage  sites, and a useful world map depicting interna�  tional time zones. More than 30 tables catalog  everything from Nobel Prize winners to chemical  elements to popes to the International System of  Units of measurement and their U.S. equivalents.  Many of the more than 190 maps have been  revised, and all of the more than 150 illustrations  have been redrawn. The more than 2,000 photo�  graphs enhance both the appearance and content  of Britannica Concise.</p><p>The editors of Encyclopaedia Britannica are proud  to present the Britannica Concise Encyclopedia. We  hope that you will consult it often and that it will  both satisfy your immediate need for information  and lead you to the in-depth information of the 40  million words of the Encyclopaedia Britannica.  Creating the highest level of reference works has  been our goal for 238 years, and we are pleased to  welcome you to the Britannica family.</p><p>Anita Wolff  Editor</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>VII</p><p>Explanatory Notes</p><p>Alphabetization. The articles are alphabetized  word by word, with further alphabetizing letter by  letter within a word. A "word" is here defined as a  unit of one or more characters set off from other  words by spaces, dashes, hyphens, or other symbols.  Entry titles consisting of more than one word are  arranged in alphabetical order of the succeeding  words. Titles with identical spellings are arranged in  the order (1) persons, (2) places, and (3) things. The  following list illustrates the word-by-word principle:</p><p>horn</p><p>Horn, Cape  Horn of Africa  hornbill  Horne, Lena  horned toad  Hornsby, Rogers</p><p>Further alphabetization rules include the follow�  ing: (1) Diacritics, apostrophes, dashes, periods,  and ampersands are ignored in alphabetization. (2)  Names of monarchs and popes that are identical  except for the Roman numeral following the name  are ordered numerically. (3) Names beginning with  Mac- and Me- are ordered literally, all names begin�  ning with Mac- preceding (by a number of pages)  all names beginning with Me-. (4) Entry headwords  beginning with numbers are alphabetized as if they  were spelled out.</p><p>Entry headword style. Variant spellings or ver�  sions of the encyclopedia's entry headwords are  printed in boldface type when they are in common  use; more obscure variants are printed in ordinary  roman type. No effort has been made to be exhaus�  tive in listing variants.</p><p>Several italicized terms are used to discriminate  among the variants. The label or simply indicates a  common alternative name or spelling. The label  orig. precedes the birth name of a person who is  entered under a name that was adopted or acquired  subsequently. When a person's original surname is  different from the name in the principal headword,  the entire birth name is given, not enclosed in  parentheses. The label known as precedes a common  way of referring to a person that may never have  had formal status. The label formerly indicates an</p><p>older and generally discarded name for an entity,  usually a geographical locale. The label officially  indicates a formal or legal version of a name. The  label in full precedes a fully spelled-out version of a  name that is usually encountered in its shorter  form. A label consisting of a language name pre�  cedes a native version or spelling of a name or term.</p><p>Biographical entry headwords in particular may  employ parentheses in several ways. Parentheses  may enclose portions of a person's name that are  rarely used, a person's original given name or  names, a later addition such as a title, or transla�  tions of titles or epithets.</p><p>drum or croaker  Odin or Wotan</p><p>Bacall, Lauren orig.

Entries for terms and names  whose pronunciation the encyclopedia's likely  users might hesitate over are supplied with pro�  nunciations. Foreign names or terms that are pro�  nounced in a markedly different way by native  speakers and English-speakers are frequently pro�  vided with two pronunciations, one of them pre�  ceded by a language label (e.g., English, French,  Spanish). Thus, for Hassan II we provide the pro�  nunciations Vha-san, English ha-'sanV The sym�  bols employed and the sounds they represent are  listed on page x.</p><p>Romanization of foreign languages. Words from  languages that do not use the Western (Roman)  alphabet generally reflect the spellings most com�  monly seen in English-language contexts.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>VIII</p><p>Chinese names are almost always transcribed  according to the Pinyin system. Where a Chinese  name or term appears as a headword, the older  Wade-Giles spelling is given as an or variant. Place-  names and biographical names on Taiwan, howev�  er, are generally listed in their Wade-Giles spelling,  with the Pinyin spelling as a variant. A few Chinese  names widely used in English (e.g., Confucius)  retain their traditional English spelling.</p><p>Japanese names and terms are generally transcribed  according to the Hepburn system but without  macrons to indicate vowel length.</p><p>Russian names and terms generally observe tradi�  tional Western spellings and follow the diacritic-  free system employed by the U.S. Board on  Geographic Names.</p><p>Arabic names and terms generally follow the best-  established Western usage. Except in a few well-  established Western transliterations, the l in the arti�  cle nl- or el- ("the") is not assimilated to a following  consonant (thus, we employ the spelling Harun nl-  Rnshid, not Harun ar-Rashld), even though such  assimilation reflects Arabic pronunciation and is  sometimes encountered in English sources.</p><p>Cross-references. Cross-references to other articles  are indicated by small capitals in sans-serif type for  the alphabetized element of the term or name. Thus,  "J. von Neumann" sends the reader to the V's, "J. W.  von Goethe" to the G's; "Cape Breton Island" sends the  reader to the C's, "Cape of Good Hope" to the G's;  and so on. In the case of personal names in which</p><p>there is no ambiguity as to alphabetical placement,  the entire name appears in small capitals.</p><p>A term is cross-referenced only when it is likely that  the reader of the article within which the cross-ref�  erence appears would want to be notified about the  additional article. Hence many terms for which  there are corresponding entries are not highlighted  as references. For instance, in the article on Tim  Berners-Lee, we have cross-referenced "World Wide  Web" (whose invention was his principal achieve�  ment) but not "Internet," which is naturally cross-  referenced within the "World Wide Web" article.  Because cross-referencing of this kind is discre�  tionary, readers should not assume that a noun  lacks its own entry simply because it is not refer�  enced within the article being read.</p><p>For the sake of saving space, many people who  receive their own entries have their given names  abbreviated and their surnames in small capitals  when they are mentioned in an article, regardless of  how likely the reader of the article is to want to be  alerted to the biographical entry. The names of  countries, U.S. states, and Canadian provinces, by  contrast, are virtually never referenced, regardless  of their centrality to a given article, on the pre�  sumption that readers will correctly assume that the  encyclopedia contains articles on all such entities.</p><p>Some 3,000 cross-references are provided at their  own alphabetical place, to direct the reader who has  looked up a variant version of the name or has  expected an entry to be alphabetized according to  an element other than the one actually used.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Abbreviations</p><p>Mass.</p><p>Md.</p><p>Massachusetts</p><p>Maryland</p><p>AD</p><p>anno Domini</p><p>Me.</p><p>Maine</p><p>Adm.</p><p>Admiral</p><p>mi</p><p>mile(s)</p><p>Ala.</p><p>Alabama</p><p>Mich.</p><p>Michigan</p><p>Amer.</p><p>American</p><p>Minn.</p><p>Minnesota</p><p>Ariz.</p><p>Arizona</p><p>Miss.</p><p>Mississippi</p><p>Ark.</p><p>Arkansas</p><p>ml</p><p>millilitre(s)</p><p>BC</p><p>before Christ</p><p>mm</p><p>millimetre(s)</p><p>C</p><p>Celsius</p><p>Mo.</p><p>Missouri</p><p>c.</p><p>circa</p><p>Mont.</p><p>Montana</p><p>Cal.</p><p>California</p><p>mph</p><p>miles per hour</p><p>Capt.</p><p>captain</p><p>N</p><p>North</p><p>cc</p><p>cubic centimetre(s)</p><p>N.C.</p><p>North Carolina</p><p>cent.</p><p>century, centuries</p><p>N.D.</p><p>North Dakota</p><p>cm</p><p>centimetre(s)</p><p>NE</p><p>northeastern</p><p>Co.</p><p>Company, County</p><p>Neb.</p><p>Nebraska</p><p>Col.</p><p>Colorado, Colonel</p><p>Nev.</p><p>Nevada</p><p>Conn.</p><p>Connecticut</p><p>N.H.</p><p>New Hampshire</p><p>Corp.</p><p>Corporation</p><p>N.J.</p><p>New Jersey</p><p>cu</p><p>cubic</p><p>N.M.</p><p>New Mexico</p><p>D.C.</p><p>District of Columbia</p><p>NW</p><p>northwestern</p><p>Del.</p><p>Delaware</p><p>N.Y.</p><p>New York</p><p>Dr.</p><p>Doctor</p><p>Okla.</p><p>Oklahoma</p><p>E</p><p>East</p><p>Ore.</p><p>Oregon</p><p>e-g-</p><p>exempli gratia (for example)</p><p>oz</p><p>ounce(s)</p><p>est.</p><p>estimate, estimated</p><p>Pa.</p><p>Pennsylvania</p><p>Eth.</p><p>Ethiopia</p><p>Ph.D.</p><p>Doctor of Philosophy</p><p>F</p><p>Fahrenheit</p><p>Pres.</p><p>President</p><p>fl.</p><p>flourished</p><p>Queen.</p><p>Queensland</p><p>Fla.</p><p>Florida</p><p>r.</p><p>reigned, ruled</p><p>ft</p><p>foot, feet</p><p>Rev.</p><p>Reverend</p><p>g</p><p>gram(s)</p><p>R.I.</p><p>Rhode Island</p><p>Ga.</p><p>Georgia</p><p>S</p><p>South</p><p>Gen.</p><p>General</p><p>s.c.</p><p>South Carolina</p><p>Gov.</p><p>Governor</p><p>S.D.</p><p>South Dakota</p><p>i.e.</p><p>id est (that is)</p><p>SE</p><p>southeastern</p><p>Ill.</p><p>Illinois</p><p>Sen.</p><p>Senator</p><p>in.</p><p>inch(es)</p><p>sq</p><p>square</p><p>Ind.</p><p>Indiana</p><p>St.</p><p>Saint</p><p>Jr-</p><p>Junior</p><p>sw</p><p>southwestern</p><p>K</p><p>Kelvin</p><p>Tenn.</p><p>Tennessee</p><p>Kan.</p><p>Kansas</p><p>UN</p><p>United Nations</p><p>k g</p><p>kilogram(s)</p><p>u.s.</p><p>United States</p><p>km</p><p>kilometre(s)</p><p>Va.</p><p>Virginia</p><p>kph</p><p>kilometres per hour</p><p>vs.</p><p>versus</p><p>Ky.</p><p>Kentucky</p><p>Vt.</p><p>Vermont</p><p>La.</p><p>Louisiana</p><p>w</p><p>West</p><p>lb, lbs</p><p>pound, pounds</p><p>w.v.</p><p>West Virginia</p><p>m</p><p>metre(s)</p><p>Wash.</p><p>Washington</p><p>M.A.</p><p>Master of Arts</p><p>Wise.</p><p>Wisconsin</p><p>Maj.</p><p>Major</p><p>Wy.</p><p>Wyoming</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Pronunciation Symbols</p><p>3</p><p>banana, collide, abut, humdrum</p><p>6</p><p>saw, all, caught</p><p>3</p><p>preceding \1\, \n\, \m\, \q\, as</p><p>ce</p><p>French boeuf, German Holle</p><p>in battle, mitten, eaten, lock and  key - 3 rj-\;

A seaport on the Atlantic Ocean, it is  believed to antedate Roman times. A point of departure for the Spanish  Armada in 1588, it was sacked by Sir Francis Drake in 1589. In the Pen�  insular War, it was the site of a notable victory by the English over the  French. It is now a large fishing centre and one of northern Spain�s most  important shipping ports.</p><p>A&amp;P See Great Atlantic &amp; Pacific Tea Co.</p><p>a posteriori See a priori</p><p>a priori \,a-pre-'or-e, .a-pri-'or-lX In epistemology, knowledge that is inde�  pendent of all particular experiences, as opposed to a posteriori (or  empirical) knowledge, which derives from experience. The terms have  their origins in the medieval Scholastic debate over Aristotelian con�  cepts (see Scholasticism). Immanuel Kant initiated their current usage,  pairing the analytic-synthetic distinction with the a priori-a posteriori  distinction to define his theory of knowledge.</p><p>Aachen Va-kon\ French Aix-la-Chapelle \,eks-la-sha-'pel\</p><p>City (pop., 1995 est.: 247,000), western Germany, southwest of  Cologne. It was inhabited by Romans in the 1st century ad. A  center of Carolingian culture, and the second city of Charle�  magne�s empire, it was the site of his great palace. The cathe�  dral built by Charlemagne c. 800 saw the coronation of most  German kings of the 10th-16th century; his chapel, with  his tomb, remains as part of the larger Gothic cathedral  today. Aachen was part of France 1801-15. It is famous  for its many spas.</p><p>Aaiun, El See Laayoune</p><p>Aalto \'al-to\, (Hugo) Alvar (Henrik) (b. Feb.</p><p>3, 1898, Kuortane, Fin., Russian Empire�d. May 11, 1976, Helsinki)  Finnish architect and designer. He graduated from the Technical Institute  of Helsinki and in 1925 married Aino Marsio, who served as his collabo�  rator. His reputation rests on a distinctive style that blends classic Mod�  ernism, indigenous materials (especially timber), and personal expression.  His unique blending of Modernism and informal regional character was  perhaps best expressed in his civic centre in Saynatsalo (1950-52), with  its simple forms in red brick, wood, and copper. He remains one of the  Modern movement�s most popular architects; reproductions of his bent  laminated wood furniture appear in households worldwide.</p><p>aardvark or African ant bear Heavily built mammal ( Orycteropus  afer) of sub-Saharan forests and  plains. Its stout, piglike body (�aard�  vark� is Afrikaans for �earth pig�)  may be as long as 6 ft (1.8 m),  including a 2-ft (60-cm) tail. It has a  long snout, rabbitlike ears, short  legs, and long toes with large, flat�  tened claws. It feeds at night by rip�  ping open ant and termite nests and  lapping up the insects with a long  (1-ft, or 30-cm), sticky tongue.</p><p>Though not aggressive, it uses claws  to fight off attackers. Its classifica�  tion with regard to other mammals is uncertain.</p><p>Aare River \'ar-o\ or Aar River River, central and northern Switzer�  land. The longest river entirely within Switzerland, it flows northwest  from the Bernese Alps and passes through the Gorge of the Aare and by  the city of Bern before flowing northeast to enter the Rhine at Koblenz,  after a course of 183 mi (294 km).</p><p>Aarhus See Arhus</p><p>Aaron (fl. 14th century bc) Brother of Moses and traditional founder and  head of the priesthood of ancient Israel. According to the Bible, he was  the spokesman for Moses and played a central role in forcing the pharaoh  to allow the Israelites to leave Egypt. God charged Aaron and Moses with  commemorating the event at Passover, and Aaron and his sons were given  priestly authority by Moses. Though Aaron is a pivotal figure in Exodus,  he nearly fades from view thereafter. He is mentioned as the one respon�  sible for the Israelites� idolatrous worship of the golden calf while Moses  was on Mount Sinai receiving the Law from God. His death at age 123  is noted in Numbers.</p><p>Aaron, Hank byname of Henry Louis Aaron (b. Feb. 5, 1934,  Mobile, Ala., U.S.) U.S. baseball  player, one of the greatest in profes�  sional baseball. After playing briefly  in the Negro leagues and then in the  minor leagues, Aaron was moved up  to the majors as an outfielder with  the Milwaukee Braves in 1954. By  the time the Braves moved to  Atlanta, Ga., in 1965, Aaron had hit  398 home runs; in 1974 he hit his  715th, breaking Babe Ruth�s record.</p><p>He played his final two seasons  (1975-76) with the Milwaukee  Brewers. Aaron�s records for  career home runs (755), extra�  base hits (1,477), and runs bat�  ted in (2,297) remain  unbroken, and only Ty Cobb  and Pete Rose exceed him in  career hits (3,771). Aaron  is renowned as one of the  greatest hitters of all time.</p><p>AARP formerly American Association of Retired  Persons Nonprofit, nonpartisan organization that  addresses the needs and interests of Americans aged 50  and older. It was founded in 1958 by a retired teacher,  Ethel Andrus, and merged in 1982 with the  National Retired Teachers Association, also  founded by Andrus (1947). Its bimonthly maga�  zine, Modern Maturity , has the largest circulation of any U.S. periodical.  Its membership exceeds 35 million. Its members� reliably high turnout at  the polls has made it one of the most powerful lobbying groups in the  country.</p><p>abacus Calculating instrument that uses beads that slide along a series  of wires or rods set in a frame to represent the decimal places. Probably  of Babylonian origin, it is the ancestor of the modern digital calculator.  Used by merchants in the Middle Ages throughout Europe and the Ara�  bic world, it was gradually replaced by arithmetic based on Hindu-Arabic  numerals. Though rarely used in Europe past the 18th century, it is still  used in the Middle East, China, and Japan.</p><p>Aba ha i See Hongtaiji</p><p>Abakanowicz V.a-ba-'kan-o-.witsV Magdalena (b.

The 'Abbasids took their name  from an uncle of the Prophet Muhammad, al-'Abbas, whose descendants  formed one of several groups agitating for change under the Umayyad  dynasty. The Umayyad enforcement of a brand of Arab chauvinism,  wherein non-Arab Muslims were relegated to a lower status, led to a  revolution in which the 'Abbasids claimed the Caliphate and enforced a  more universal community of believers. This was symbolized by their  movement of the caliphal capital from Damascus to Baghdad, an area  closer to the geographic centre of the empire and nearer the Persian hin�  terland. Under their rule, Islamic culture flourished, new heights in phi�  losophy and science were attained, and the period was widely seen as the</p><p>�golden age� of the Islamic world. During that time, however, the Caliph�  ate�s authority slowly began to erode as regional power centres devel�  oped throughout the empire. Although central authority was intermittently  reasserted by strong-willed caliphs, by the 13th century 'Abbasid author�  ity was largely spiritual. The last 'Abbasid caliph was executed by Mon�  gol invaders, but a shadow Caliphate (of dubious authenticity) continued  into the early 20th century.

There he painted portraits and decorated palaces with  frescoes of landscapes and figure compositions in the Mannerist style. In  1552 he was invited by Henry II of France to work under Primaticcio at  the Palace of Fontainebleau, where he executed immense murals (most  now lost). He remained in France the rest of his life.

The first abbey was Monte Cassino in Italy, founded in  529 by St. Benedict of Nursia. The cloister linked the most important ele�  ments of an abbey together. The dormitory was often built over the din�  ing hall on the eastern side of the cloister and linked to the central church.  The western side of the cloister provided for public dealings, with the  gatehouse controlling the only opening to the outer, public courtyard. On  the southern side of the cloister were a central kitchen, brewery, and  workshops. The novitiate and infirmary were housed in a building with  its own chapel, bathhouse, dining hall, kitchen, and garden.

He also wrote an autobiography, Historia calamitatum, and his best-  known work is the series of letters he exchanged with Heloi'se after they  retired to monasteries.</p><p>Abenaki \,a-b3-'na-ke\ or Abnaki Confederacy of Algonquian-  speaking North American Indian peoples living mostly in Quebec, Can.,  and Maine, U.S. The contemporary Abenaki consider their home territory  to be southern Quebec and the U.S. states of Vermont and New Hamp�  shire, as well as parts of Maine and New York. Their name means �people  of the dawn� or �easterners.� The name is applied to a number of groups�  including Androscoggin, Kennebec, Maliseet, Ouarastegouiak, Passama-  quoddy, Patsuiket, Penobscot, Pigwacket, Micmac, Pennacook,  Rocameca, Sokoni, and Wewenoc�who formed the Abenaki confedera�  tion in order to resist the Iroquois Confederacy, especially the Mohawk.  In the 17th century the Abenaki sided with the French against the English,  but, after severe defeats, they withdrew to Canada, many eventually set�  tling at Saint-Frangois-du-Lac and Becancour, near Trois-Rivieres, in  Quebec. There are also reservations in Maine and in New Brunswick, Can.  The total population of Abenaki is about 12,000.</p><p>Abeokuta ya-'ba-o-.kii-taX City (pop., 2002 est.: 529,700), southwest�  ern Nigeria. Located about 50 mi (80 km) north of Lagos, Abeokuta was  established c. 1830 as a refuge from intertribal wars. It was the chief town  of the Egba, who long maintained a working relationship with the Brit�  ish; not until 1914 was it incorporated into British Nigeria. The modem  town is an agricultural and exporting centre.</p><p>Aberdeen City, council area (pop., 2001: 212,125), and commercial  port on the North Sea, eastern Scotland. It constitutes the council area of  Aberdeen, an enclave within the surrounding council area of Aberdeen�  shire, which was also the name of the historic county of which Aberdeen  was the seat. Situated at the mouths of the Rivers Dee and Don, it is the  chief port of northern Scotland. It was a royal burgh from the 12th cen�  tury and a Scottish royal residence in the 12th-14th centuries. It supported  Robert the Bruce in wars for Scottish independence, and for a time it was  the headquarters of Edward I. From the 1970s Aberdeen developed rap�  idly as the principal British centre of the North Sea oil industry and its  associated service and supply industries.</p><p>Aberdeen, George Hamilton-Gordon, 4th earl of (b. Jan. 28,  1784, Edinburgh, Scot.�d. Dec. 14, 1860, London, Eng.) British foreign  secretary and prime minister (1852-55). As special ambassador to Aus�  tria in 1813, he helped form the coalition that defeated Napoleon. As for�  eign secretary (1828-30, 1841-46), he settled boundary disputes between  Canada and the U.S. with the Webster-Ashburton Treaty and the Oregon  Treaty (see Oregon Question). As prime minister, he formed a coalition  government, but his indecision hampered peacekeeping efforts and led to  Britain�s involvement in the Crimean War. Constitutionally responsible for  the mistakes of British generals in the war, he resigned in 1855.</p><p>Aberhart Va-bor-.hartA, William (b. Dec. 30, 1878, Kippen, Ont.,  Can.�d. May 23, 1943, Vancouver, B.C.) Canadian politician and the  country�s first Social Credit Party premier (Alberta, 1935-43). Aberhart  was a high school principal in Calgary, Alta. (1915-35). An active lay  preacher, he founded the Calgary Prophetic Bible Institute (1918). In 1932  he used his evangelical rhetoric to promote monetary-reform theories to  solve the economic problems created in Alberta by the Great Depression,  proposing to issue dividends (social credit) to each person, based on the  real wealth of the province. When his party won a majority in the 1935  provincial election, he became premier and minister of education, but his  social-credit proposals were disallowed by the federal government.</p><p>Abernathy Vab-or-.nath-eN, Ralph David (b. March 11, 1926, Lin�  den, Ala., U.S.�d. April 17, 1990, Atlanta, Ga.) U.S. pastor and civil  rights leader. He was educated at Alabama State University and Atlanta  University. Ordained a Baptist minister in 1948, he became pastor of the  First Baptist Church in Montgomery, Ala., in 1951. He met Martin Luther  King, Jr., a few years later when the latter became pastor of another Bap�  tist church in Montgomery. In 1955-56 the two men organized a nonvio�  lent boycott of the city bus system, marking the beginning of the U.S. CIVIL  rights movement. In 1957 they founded the Southern Christian Leadership  Conference. Abernathy became its president on King�s assassination in</p><p>1968; in 1977 he resigned to resume work as a pastor in Atlanta. His  autobiography, And the Walls Came Tumbling Down, appeared in 1989.</p><p>aberration Deviation of light rays by LENSes or curved mirrors which  causes the images to be blurred. Spherical aberration occurs because cur�  vature in a lens or mirror causes rays falling on the outer edges to be  brought to a focus at a different point than those falling on the middle. This  makes the images formed appeal - blurred. Chromatic aberration, which  occurs in lenses but not mirrors, is the failure of a lens to focus all colours  (wavelengths) of light in the same plane; the image appears blurred and  shows rainbow-coloured fringes around the edges. See also astigmatism.</p><p>aberration of starlight Apparent displacement of a star or other  celestial body resulting from Earth�s orbital motion around the Sun. The  maximum displacement is about 20.49 seconds of arc. It depends on the  ratio of Earth�s orbital speed to the speed of light and Earth�s direction  of motion and thus provides confirmation that Earth orbits the Sun rather  than the reverse.</p><p>Aberystwyth X.a-bo-'ris-.twithX Town (pop., 1991: 11,154) on Cardi�  gan Bay, western Wales.

A principal stronghold of Welsh culture, it has grown  as a seaside resort.</p><p>Abhayagiri \ab-'ya-go-re\ Theravada Buddhist monastic center built at  Anuradhapura, then capital of Ceylon, by King Vattagamani Abhaya (r.  29-17 bc). Originally associated with the nearby Mahavihara (�Great Mon�  astery�), it soon seceded in a dispute over the relations between monks and  the lay community and the use of Sanskrit works to augment Pali texts as  scripture. It gained wealth and power under the patronage of Gajabahu I (ad  113-35) and flourished until Anuradhapura was abandoned in the 13th cen�  tury. Two of its main colleges operated into the 16th century.</p><p>Abhidhamma Pitaka V.a-bi-'da-mo-'pe-ta-koX Third and latest collec�  tion of texts comprising the Pali canon (see Tripitaka) of Theravada Bud�  dhism. The first two collections, Sutta Pitaka and Vinaya Pitaka, are  attributed to the Buddha. Abhidhamma Pitaka texts are ascribed to later dis�  ciples and scholars; they deal with ethics, psychology, and epistemology.</p><p>Abhidharmakosa V.a-bi-.dar-mo-'ko-soX Buddhist scholarly work  that provides an introduction to the seven Abhidharma treatises in the  Sarvastivada canon and a digest of their contents. It was composed by the  Buddhist monk Vasubandhu (fl. 4th or 5th century), who lived in north�  western India. It systematizes Sarvastivada doctrine and shows the influ�  ence of Mahayana, to which Vasubandhu later converted. It provides much  information on doctrinal differences among the ancient Buddhist schools.</p><p>abhijna \3-'bij-n9\ In Buddhist philosophy, the miraculous powers  obtained through meditation and wisdom. They include the ability to  travel any distance or take any form at will, to see everything, to hear  everything, to read minds, and to recall former existences. A sixth miracu�  lous power, available only to Buddhas and arhats (saints), is freedom by  undefiled wisdom (Enlightenment). The powers are signs of spiritual  progress but their indulgence is a distraction from the path toward Enlight�  enment.</p><p>Abidjan \,a-be-'jan\ Largest city (pop., 1999 est.: 3,199,000) and chief  port of Cote d�Ivoire. Abidjan was a rail terminus from 1904; after its  lagoon was opened to the sea to create a port (1950), the city became the  financial centre of French West Africa. Though it was once the country�s  capital and remains its seat of government, the official capital was moved  to Yamoussoukro in 1983. Abidjan has a museum of traditional Ivorian  art, a national library, and several research institutes.</p><p>Abilene Town (pop., 2000: 6,543), Kansas, U.S. It lies on the Smoky  Hill River east of Salina. Settled in 1858, it gained importance when it  became the railway terminus for overland Texas cattle drives. With the  prosperity of the cattlemen came an era of lawlessness; Wild Bill Hickok  was its marshal in 1871. Pres. Dwight D. Eisenhower spent his boyhood  there and is buried at the Eisenhower Center, which includes his family  home and library.</p><p>Abilene City (pop., 2000: 115,930), west-central Texas, U.S. Founded  in 1881 as the new railhead for the overland Texas cattle drives, it took  the business of the previous railhead, Abilene, Kan.

Blood can  be type O (lacking both), type A (having only A), type B (having only B),  or type AB (having both). The ABO antigens make certain blood types  incompatible for transfusion. They are developed well before birth and  remain through life. The frequencies of blood groups vary among differ�  ent racial groups and in different geographic areas. Certain diseases are  rarer in persons with particular blood groups.</p><p>abolitionism (c. 1783-1888) Movement to end the slave trade and  emancipate slaves in western Europe and the Americas. The slave system  aroused little protest until the 18th century, when rationalist thinkers of  the Enlightenment criticized it for violating the rights of man, and Quaker  and other evangelical religious groups condemned it as un-Christian.  Though antislavery sentiments were widespread by the late 18th century,  they had little immediate effect on the centres of slavery themselves�the  West Indies, South America, and the southern U.S. In 1807 the importa�  tion of African slaves was banned in the U.S. and the British colonies.  Slavery was abolished in the British West Indies by 1838 and in the French  possessions 10 years later. In the 11 Southern states of the U.S., however,  slavery was a social and economic institution. American abolitionism  laboured under the handicap that it threatened the harmony of North and  South in the Union, and it also ran counter to the U.S. Constitution, which  left the question of slavery to the individual states. The abolitionist move�  ment in the North was led by agitators such as William Lloyd Garrison,  founder of the American Anti-Slavery Society, writers such as John Green-  leaf Whittier, former slaves such as Frederick Douglass, and Harriet Beecher  Stowe. The election of Abraham Lincoln, who opposed the spread of sla�  very to the West, marked a turning point in the movement. Convinced  that their way of life was threatened, the Southern states seceded from the  Union (see secession), which led to the American Civil War. In 1863 Lin�  coln (who had never been an abolitionist) issued the Emancipation Proc�  lamation, which freed slaves held in the Confederate states; the 13th  Amendment to the U.S. Constitution (1865) prohibited slavery through�  out the country. Slavery was abolished in Latin America by 1888. In some  parts of Africa and in much of the Islamic world, it persisted as a legal  institution well into the 20th century.</p><p>Abominable Snowman Tibetan Yeti Mythical monster believed to  inhabit the Himalayas near the snow line. The Yeti is thought to resemble  an oversized man covered with shaggy fur. Reported sightings are rare;  evidence of its existence consists largely of unusual footprints left in the  snow, probably the tracks of bears. At certain gaits, bears place the hind-  foot partly over the imprint of the forefoot, thus creating tracks that  resemble the footprints of a very large primate heading in the opposite  direction.</p><p>Aborigine See Australian Aboriginal</p><p>abortion Expulsion of a fetus from the uterus before it can survive on  its own. Spontaneous abortion at earlier stages of pregnancy is called mis�  carriage. Induced abortions often occur through intentional medical inter�  vention and are performed to preserve the woman�s life or health, to  prevent the completion of a pregnancy resulting from rape or incest, to  prevent the birth of a child with serious medical problems, or because the  woman does not believe she is in a position to rear a child properly. The  drug RU-486, if taken within a few weeks of conception, will trigger a  miscarriage. Up to about 19 weeks of pregnancy, injections of saline  solutions or hormones may be used to stimulate uterine contractions that  will expel the fetus. Surgical removal of the contents of the uterus may  be performed in the second trimester or later. Intact dilation and extrac�  tion procedures may occur in the third trimester; sometimes critically  referred to as �partial-birth abortions,� they have been very controversial.  Other abortion procedures include manual vacuum aspiration (extraction  by manual syringe) and dilation and suction curettage (extraction by  machine-operated suction), both of which can be performed in early preg�</p><p>nancy. The social acceptability of abortion as a means of population con�  trol has varied from time to time and place to place throughout history. It  was apparently a common method of family limitation in the Greco-  Roman world, but Christian theologians early and vehemently condemned  it. It became widely accepted in Europe in the Middle Ages. Severe crimi�  nal sanctions to deter abortion became common in the 19th century, but  in the 20th century those sanctions were gradually modified in many  countries. In the U.S. the 1973 Roe v. Wade decision had the effect of  legalizing abortion during the first three months of pregnancy; states were  able to implement restrictions on access to abortion after the first trimes�  ter, though within constraints set by the courts. Since that decision, there  has been a fierce debate between supporters and opponents of a liberal�  ized abortion policy.</p><p>Abraham (fl. early 2nd millennium bc) First of the Hebrew patriarchs,  revered by Judaism, Christianity, and Islam. Genesis tells how Abraham, at  75, left Ur with his barren wife, Sarai (later Sarah), and others to found  a new nation in Canaan. There God made a covenant with him, prom�  ising that his descendants would inherit the land and become a great  nation. Abraham fathered Ishmael by Sarah�s maidservant Hagar; Sarah  herself bore Isaac, who inherited the covenant. Abraham�s faith was tested  when God ordered him to sacrifice Isaac; he was prepared to obey but  God relented. In Judaism he is a model of virtue, in Christianity he is the  father of all believers, and in Islam he is an ancestor of Muhammad and a  model (in Sufism) of generosity.</p><p>Abraham, Karl (b. May 3, 1877, Bremen, Ger.�d. Dec. 25, 1925,  Berlin) German psychoanalyst. He helped establish the first branch of the  International Psychoanalytic Institute in 1910 and pioneered the psycho�  analytic treatment of manic-depressive psychosis (bipolar disorder). He  suggested that the sexual drive develops in six stages and that if devel�  opment is arrested at any of the earlier stages, mental disorders will likely  result from fixation at that level. His most important work was A Short  Study of the Development of the Libido (1924).</p><p>Abraham, Plains of Plateau located west of the old walled city of  Quebec, Canada. On Sept. 13, 1759, it was the scene of the decisive battle  of the French and Indian War, in which the British under James Wolfe  defeated the French under the marquis de Montcalm.

Its capital is L'Aquila. Most of the region is moun�  tainous or hilly, traversed by the Apennines. The ancient Italic tribes of the  region long resisted conquest by the Romans. The Normans established  themselves in the 12th century, and the region later sided with the Hohen-  staufens against the papacy. As Abruzzi e Molise, the area became part of  the Kingdom of Italy in 1860-61; in 1965 it was divided into the separate  regions of Abruzzo and Mouse. The economy is primarily agricultural.</p><p>Absalom (fl. c. 1020 bc, Palestine) In ancient Israel, the third and most  beloved son of David. His story is told in 2 Samuel 13-19. An attractive  but lawless man, he killed his half brother Amnon as revenge for the lat�  ter�s rape of Tamar, Absalom�s sister, and was banished from the king�  dom for a time. He later raised a rebellion against his father, capturing  Jerusalem but meeting defeat in the forest of Ephraim, where he was killed  by his cousin Joab, who found him caught by the hair in an oak tree.

Criticized for centuries as an eco�  nomic injustice, absentee ownership was a feature of pre-Revolutionary  France and English rule of Ireland. Ending the practice continues to be a  goal of LAND reform programs in many developing countries.</p><p>absolute value Measure of the magnitude of a real number, complex  number, or vector. Geometrically, the absolute value represents (absolute)  displacement from the origin (or zero) and is therefore always nonnega�  tive. If a real number a is positive or zero, its absolute value is itself; if  a is negative, its absolute value is -a. A complex number z is typically  represented by an ordered pair {a, b ) in the complex plane. Thus, the  absolute value (or modulus) of z is defined as the real number v&lt; 2 2 + b 2 ,  which corresponds to z� s distance from the origin of the complex plane.  Vectors, like arrows, have both magnitude and direction, and their alge�  braic representation follows from placing their �tail� at the origin of a  multidimensional space and extracting the corresponding coordinates, or  components, of their �point.� The absolute value (magnitude) of a vector  is then given by the square root of the sum of the squares of its compo�  nents. For example, a three-dimensional vector v, given by (a , b, c), has  absolute value Va 2 + b 2 + c 2 . Absolute value is symbolized by vertical  bars, as in \x\, \z\, or |v|, and obeys certain fundamental properties, such  as \a &#x25A0; b\ = \a\ � \b\ and \a + b\ &lt; \a\ + \b.</p><p>absolute zero Temperature at which a thermodynamic system (see  thermodynamics) has the lowest energy, 0 kelvin (K). It corresponds to  -459.67�F (-273.15�C) and is the lowest possible temperature theoreti�  cally achievable by a system. A gas at constant pressure contracts as the  temperature is decreased. A perfect gas would reach zero volume at abso�  lute zero. However, a real gas condenses to a liquid or a solid at a tem�  perature higher than absolute zero. At absolute zero, the system�s  molecular energy is minimal and none is available for transfer to other  systems. The Kelvin temperature scale has absolute zero as its zero point,  and its fundamental unit is the kelvin.</p><p>absolution In Christianity, a pronouncement of forgiveness of sins  made to a person who has repented. This rite is based on the forgiveness  that Jesus extended to sinners during his ministry. In the early church, the  priest absolved repentant sinners after they had confessed and performed  their penance in public. During the Middle Ages, it became the custom  for priests to hear confession and grant absolution privately. In Roman  Catholicism penance is a sacrament, and the priest has the power to absolve  a contrite sinner who promises to make satisfaction to God. In Protestant  churches, the confession of sin is usually made in a formal prayer by the  whole congregation, after which the minister announces their absolution.</p><p>absolutism Political doctrine and practice of unlimited, centralized  authority and absolute sovereignty, especially as vested in a monarch. Its  essence is that the ruling power is not subject to regular challenge or check  by any judicial, legislative, religious, economic, or electoral agency.  Though it has been used throughout history, the form that developed in  early modern Europe (16th-18th century) became the prototype; Louis XIV  is seen as the epitome of European absolutism. Religious authority was  assumed by the monarch, who became the head of the church as well as  the state, on the basis that the right to rule came from God (see divine  kingship). See also AUTHORITARIANISM, dictatorship, totalitarianism.</p><p>absorption Transfer of energy from a wave to the medium through  which it passes. The energy of the wave can be reflected, transmitted, or  absorbed. If the medium absorbs only a fraction of the energy, it is said  to be transparent to that energy. When all energy is absorbed, the medium  is opaque. All substances absorb energy to some extent. For instance, the  ocean appears transparent to sunlight near the surface, but becomes  opaque with depth. Substances absorb specific types of radiation. Rubber  is transparent to infrared radiation and X rays, but opaque to visible light.</p><p>Green glass is transparent to green light but absorbs red and blue light.  Absorption of sound is fundamental to acoustics; a soft material absorbs  sound energy as the waves strike it.</p><p>abstract art or nonobjective art or nonrepresentational art</p><p>Art, including painting, sculpture, and graphic art, that does not represent  recognizable objects. In the late 19th century the traditional European  conception of art as the imitation of nature was abandoned in favour of  the imagination and the unconscious. Abstraction developed in the early  20th century with such movements as Fauvism, Expressionism, Cubism, and  Futurism. Vasily Kandinsky is credited as the first modem artist to paint  purely abstract pictures, c. 1910. Piet Mondrian�s De Stijl group in The  Netherlands widened the spectrum c. 1915-20. Abstraction continued to  flourish between the two world wars, and after the 1930s it was the most  characteristic feature of Western art. After World War II, Abstract Expres�  sionism emerged in the U.S. and had a great influence on European and  American painting and sculpture. By the turn of the 21st century, artistic  output was varied, with abstract art prominent alongside figurative and  conceptual work.</p><p>Abstract Expressionism Movement in U.S. painting that began in  the late 1940s. Its development was influenced by the radical work of  Arshile Gorky and Hans Hofmann and by the immigration in the late 1930s  and early �40s of many European avant-garde artists to New York. The  Abstract Expressionist movement itself is generally regarded as having  begun with the paintings done by Jackson Pollock and Willem de Kooning  in the late 1940s and early �50s. Other artists who came to be associated  with the style include Franz Kune, Mark Rothko, Clyfford Still, Philip Gus-  ton, Helen Frankenthaler, Barnett Newman, Adolph Gottlieb, Robert Moth�  erwell, Lee Krasner, and Ad Reinhardt. The movement comprised many  styles but shared several characteristics. The works were usually abstract  (i.e., they depicted forms not found in the natural world); they empha�  sized freedom of emotional expression, technique, and execution; they  displayed a single unified, undifferentiated field, network, or other image  in unstructured space; and the canvases were large, to enhance the visual  effect and project monumentality and power. The movement had a great  impact on U.S. and European art in the 1950s; it marked the shift of the  creative centre of modem painting from Paris to New York.

It has numerous offshore islands, and inter�  nally it partially surrounds Dubayy and has a short boundary with  Al-Shariqah (Sharjah). Since the 18th century the A1 Bu Falah, a clan of  the Banu Yas confederation, has held power. In 1761 they found wells of  potable water at the site of Abu Dhabi city, and they made their headquar�  ters there from 1795. In the 19th century territorial conflicts with Muscat  (Masqat) and Oman and with the ancestors of the Sa�0d dynasty (which  now rules Saudi Arabia) led to border disputes that have remained largely  unsettled. Abu Zabi signed an agreement with Great Britain in 1892,  placing its foreign affairs under British control. When Britain withdrew  from the Persian Gulf in 1968, the emirate and the other Trucial States  formed the United Arab Emirates. Its rich oil fields make it and Dubayy  the federation�s two most prosperous emirates.</p><p>Abu Zayd \ab-u-'zld\, Nasr Hamid (b. Oct. 7, 1943, Tanta, Egypt)  Egyptian scholar. He attended Cairo University and received a Ph.D. in  Arab and Islamic studies. His research and writings on Quranic exegesis,  including his well-known Critique of Islamic Discourse (1995), offended  some Islamic fundamentalists. In 1993 a colleague denounced him in a  major Cairo mosque, and Islamic radicals successfully sought a nullifi�  cation of his marriage from an Egyptian family court on the grounds that  his writings demonstrated his apostasy (and under Egyptian law a Mus�  lim woman may not be married to a non-Muslim man). Though the court  declined to pass judgment, an appeals court divorced Abu Zayd and his  wife, a decision confirmed by the Egyptian Supreme Court. The case  attracted widespread concern among intellectuals and human rights  groups. Since 1995 Abu Zayd and his wife have lived in exile in The  Netherlands.</p><p>Abuja \a-'bii-ja\ City (pop., 2003 est.: 452,000), federal capital of Nige�  ria. Construction of the city, at a site chosen for its healthful climate and  central location about 300 mi (480 km) northeast of Lagos, began in 1976  under the architect Tange Kenzo. It officially replaced Lagos as the capi�  tal in 1991.</p><p>Abydos \3-'bi-d9s\ Sacred city, one of the most important archaeologi�  cal sites of ancient Egypt. It was a royal necropolis of the first two dynas�  ties and later a pilgrimage centre for the worship of Osiris. The pharaohs,  including Thutmose III and Ramses III, embellished the temple to Osiris, and  some pharaohs had cenotaphs at Abydos. The temple of Seti I, one of the  most beautiful, has helped decode Egyptian history: in a long gallery is a</p><p>relief, the so-called Abydos list of kings, showing Seti and his son Ram�  ses making offerings to the cartouches of 76 dead predecessors.</p><p>Abydos Ancient Anatolian town northeast of modern Qanakkale, Tur�  key, on the eastern side of the Dardanelles. It was colonized c. 670 bc by  the Milesians (see Miletus). Xerxes I crossed the strait on a bridge of boats  to invade Greece in 480 bc. Abydos is celebrated for its resistance to Philip  V of Macedon in 200 bc and for the legend of Hero and Leander.</p><p>abyssal plain \3-'bis-3l\ Flat seafloor area at a depth of 10,000-20,000  ft (3,000-6,000 m), generally adjacent to a continent. The larger plains  are hundreds of miles wide and thousands of miles long. The plains are  largest and most common in the Atlantic Ocean, less common in the  Indian Ocean, and even rarer in the Pacific Ocean, where they occur  mainly as small, flat floors of marginal seas or as long, narrow bottoms  of trenches. They are thought to be the upper surfaces of land-derived  sediment that accumulates in abyssal depressions.</p><p>Abyssinia See Ethiopia</p><p>Abyssinian cat \,ab-3-'si-ne-3n\ Breed of domestic cat, considered  more similar to the sacred cat of ancient Egypt than any other living cat.  It is lithe and has slender legs and a long, tapering tail. Its short, finely  textured coat is ruddy reddish brown, with individual hairs distinctively  ticked, or tipped, with bands of black or brown. The nose is red, and the  tail tip and backs of the hindlegs are black. The Abyssinian is affection�  ate and quiet, though generally shy with strangers.</p><p>Abzug Vab-z3g\, Bella orig. Bella Savitzky (b. July 24, 1920, New  York, N.Y., U.S.�-d. March 31, 1998, New York City) U.S. lawyer and  politician. She studied law at Columbia University and subsequently took  on numerous union, civil liberties, and civil rights cases, representing  several people charged by Sen. Joseph McCarthy. She founded and chaired  (1961-70) the antiwar Women Strike for Peace and later the National  Women�s Political Caucus. In the House of Representatives (1971-77),  she was known for her flamboyant style, her opposition to the Vietnam  War, and her outspoken support for the Equal Rights Amendment, abor�  tion rights, and child-care legislation.</p><p>AC See ALTERNATING CURRENT</p><p>acacia \9-'ka-sh3\ Any of the approximately 800 species of trees and  shrubs that make up the genus Aca�  cia, of the mimosa family. Acacias are  native to tropical and subtropical  regions of the world, particularly  Australia and Africa. Sweet acacia  (A. farnesiana ) is native to the south�  western U.S. Acacias have distinc�  tive, finely divided leaflets, and their  leafstalks may bear thorns or sharp  spines at their base. Their small,  often fragrant, yellow or white flow�  ers have many stamens apiece, giv�  ing each a fuzzy appearance. On the  plains of southern and eastern Africa,  acacias are common features of the  landscape.

The awards (nick�  named Oscars) recognize excellence in acting, directing, screenwriting,  and other activities related to film production.</p><p>Acadia North American possession of France in the 17th�18th century,  centred in what is now Nova Scotia. Acadia was probably intended to  include the other present Maritime Provinces as well as parts of Maine and  Quebec. The first European settlement was founded by Samuel de Cham�  plain and Pierre du Gast in 1604. The area at times was also claimed by  the British and was contested often in the 18th-century colonial wars; in  1713 Nova Scotia came under British rule. In 1755 many French-speaking  Acadians were deported by the British because of imminent war with  France; several thousand settled in French-ruled Louisiana, where their  descendants were known as Cajuns. The event was the theme for Henry  W. Longfellow�s Evangeline.</p><p>Acadia National Park Preserve on the coast of Maine, U.S. It has  an area of 65 sq mi (168 sq km). Originally established as Sieur de Monts  National Monument (1916), it became the first national park in the east�  ern U.S. as Lafayette National Park (1919) and was renamed Acadia in  1929. It consists mainly of a forested area on Mount Desert Island, domi�  nated by Cadillac Mountain.</p><p>Acadia University Privately endowed university in Wolfville, Nova  Scotia, Canada. Founded in 1838, it took its current name and status in  1891. It has faculties of arts, professional studies, science, theology, edu�  cation, and graduate studies. Acadia ranks among the country�s top under�  graduate institutions.</p><p>Acadian orogeny Vs-'ka-de-on-o-'ra-jo-neV Mountain-building event  that affected the northern portion of the Appalachian Geosyncune from  present-day New York to Newfoundland during the Devonian period. The  orogeny was most intense in northern New England. Its origin has been  ascribed to the collision of the northeastern portion of the North Ameri�  can Plate with western Europe. Evidence for the orogeny includes defor�  mation of pre-Devonian and Devonian rocks.</p><p>acanthus \3-'kan-thos\ Any of the more than 2,500 plant species that  make up the family Acanthaceae, of the figwort order. Acanthus are found  mostly in tropical and subtropical regions. Most are herbaceous plants or  shrubs that grow in tropical rainforests; some are climbers (vines) or trees.  Acanthus have simple leaves arranged in opposite pairs on the twigs and  enlarged cells called cystoliths in streaks or protuberances in the vegeta�  tive parts. The bisexual flowers are bilaterally symmetrical and usually  crowded together in clusters. Individual flowers are enclosed by leaflike  bracts, which are often coloured and large. Acanthus are mainly of hor�  ticultural interest and include some ornamentals.</p><p>Acapulco in full Acapulco de Juarez City and port (pop., 2000:  619,253), southwestern Mexico. Situated on a deep semicircular bay, it  has the best harbour on Mexico�s Pacific coast. It was discovered by  Hernan Cortes in 1531, and a settlement was founded in 1550. Until 1815  it was a main depot for Spanish colonial fleets going to the Far East. It  has become a major international resort for tourists attracted by its sce�  nic beauty, climate, and excellent beaches.</p><p>Acarnania V.a-kor-'na-ne-oV District, ancient Greece, bounded by the  Ionian Sea, the Ambracian Gulf, and the Achelous River. First settled in  the 7th-6th centuries bc, it developed into a federal state by the late 5th  century bc; its capital was Stratus. It later came under Athenian, Theban,  and Macedonian rule. Part of Acarnania recovered its independence in  231 bc and began an alliance with Philip V of Macedon. Rome overthrew  the Macedonian dynasty in 167 bc, and Acarnania survived until Augus�  tus incorporated many Acamanians into his new city Nicopolis Actia.</p><p>acceleration Rate of change of velocity. Acceleration, like velocity, is  a vector quantity: it has both magnitude and direction. The velocity of an</p><p>object moving on a straight path can change in magnitude only, so its  acceleration is the rate of change of its speed. On a curved path, the  velocity may or may not change in magnitude, but it will always change  in direction, which means that the acceleration of an object moving on a  curved path can never be zero. If velocity is stated in metres per second  (m/s) and the time interval in seconds (s), then the units of acceleration  are metres per second per second (m/s/s, or m/s 2 ). See also centripetal  ACCELERATION.</p><p>accelerator, particle See particle accelerator</p><p>accelerometer \ik- 1 se-b- , ra-m3-t3r\ Instrument that measures accel�  eration. Because it is difficult to measure acceleration directly, the device  measures the force exerted by restraints placed on a reference mass to hold  its position fixed in an accelerating body. The output is usually either a  varying electrical voltage or displacement of a moving pointer over a fixed  scale. Specially designed accelerometers are used in varied applications:  control of industrial vibration test equipment, detection of earthquakes  (seismographs), and input to navigational and inertial guidance systems.</p><p>accent In prosody, a rhythmically significant stress on the syllables of a  verse, usually at regular intervals. Though the term is often used inter�  changeably with stress, some prosodists use accent to mean the empha�  sis determined by normal language usage and stress to mean emphasis  determined by metrical pattern.</p><p>acceptance Short-term credit instrument consisting of a written order  that requires a buyer to pay a specified sum to the seller at a given date,  signed by the buyer as a promise to honor the obligation. Acceptances are  often used in export/import transactions: an exporter may require a buyer  to sign and return an acceptance, which the exporter can then sell to the  bank at a discount, thereby obtaining payment promptly. The buyer then  has until the bill�s maturity date to dispose of the goods and pay the  promised sum (now owed to the bank). See also bill of exchange; promis�  sory note.</p><p>acclimatization Any of numerous gradual, long-term responses of an  individual organism to changes in its environment. The responses are  more or less habitual and reversible should conditions revert to an earlier  state. These criteria differentiate acclimatization from homeostasis; from  growth and development (which cannot be reversed); and from evolution�  ary adaptation (which occurs in a population over generations). Acclima�  tization can occur in anticipation of a change and enable organisms to  survive conditions beyond their natural experience. Examples include  adaptations to seasonal changes and adjustments to changes in altitude.</p><p>accordion Portable musical instrument that uses a hand-pumped bel�  lows and two keyboards to sound  free reeds, small metal tongues that  vibrate when air flows past them.</p><p>The keyboards on either side of the  bellows effectively resemble indi�  vidual reed organs. The right-hand  keyboard plays the treble line or  lines. Most of the keys on the left-  hand (bass) keyboard sound three-  note chords; �free-bass� accordions  permit the playing of single-note  lines. A prototype accordion, using  buttons rather than keys, was pat�  ented in Berlin in 1822 by Friedrich  Buschmann (also inventor of the har�  monica). The instrument gained wide popularity in dance bands and as a  folk instrument. See also concertina.</p><p>account payable Any amount owed as the result of a purchase of  goods or services on a credit basis. Although a firm making a purchase  issues no written promise of payment, it enters the amount owed as a cur�  rent liability in its accounts. Companies often incur this type of short�  term debt in order to finance their inventories, especially in industries  where inventory turnover is rapid. See also account receivable.</p><p>account receivable Any amount owed to a business as the result of a  purchase of goods or services from it on a credit basis. Although the firm  making the sale receives no written promise of payment, it enters the  amount due as a current asset in its books.

The actual recording and sum�  marizing of financial transactions is known as bookkeeping. When the data  thus produced are abstracted in reports (usually quarterly or annually) for  the use of persons outside the organization, the process is called finan�  cial accounting. Three reports are typically generated in financial account�  ing: the balance sheet, which summarizes the firm�s assets and liabilities;  the income statement, which reports the firm�s gross proceeds, expenses,  and profit or loss; and the statement of cash flow, which analyzes the flow  of cash into and out of the firm. The creation of reports (usually monthly)  for internal planning and decision-making is called managerial account�  ing. Its aim is to provide managers with reliable information on the costs  of operations and on standards with which those costs can be compared,  to assist them in budgeting.</p><p>Accra Va-kro, o-'kra\ Capital and largest city (pop., 2001 est.: 1,551,200)  of Ghana, on the Gulf of Guinea. When the Portuguese first settled on the  coast in 1482, the site was occupied by the Ga people. Three fortified  trading posts were built 1650-80 by the Danes, the Dutch, and the Brit�  ish. The Danes and Dutch left the region in 1850 and 1872, respectively,  and in 1877 Accra became the capital of the British Gold Coast colony.  The city became Ghana�s administrative, economic, and educational cen�  tre after the country gained its independence in 1957. Tema, 17 mi (27  km) east, has taken over Accra�s former port functions.</p><p>acculturation See culture contact</p><p>accused, rights of the In law, the rights and privileges of a person  accused of a crime. In most modem legal systems these include the pre�  sumption of innocence until proved guilty, trial by jury, representation by  counsel, the right to present witnesses and evidence to establish one�s  innocence, and the right to cross-examine one�s accusers. Also important  are a prohibition against an unreasonable search and seizure, the right to a  speedy trial, and guarantees of freedom from double jeopardy and of the  right to appeal. In the U.S. a person accused of a crime must be notified  immediately of the right to secure counsel and the right to refuse to answer  questions if answering might be incriminating (see Miranda v. Arizona ).</p><p>acetaminophen Vs-.se-to-'min-o-fonV Drug used to relieve mild head�  ache or muscle and joint pain and to reduce fever. An organic compund, it  relieves pain by inhibiting prostaglandin synthesis in the central nervous  system and reduces fever by acting on the temperature-regulating centre  of the brain. Unlike aspirin, it has no anti-inflammatory effect. It also is  much less likely to irritate the stomach and cause peptic ulcers, is not linked  with Reye syndrome, and can be taken by persons using anticoagulants or  allergic to aspirin. Overdosages can cause fatal liver damage. A common  brand name in much of the world is Tylenol. See also ibuprofen.</p><p>acetate C 2 H 3 0 2 _ ion, a salt, ester, or acylal derived from acetic acid.  Acetates are important in the biochemical synthesis of fats from carbo�  hydrates in plants and animals. Industrially, metal acetates are used in  printing, vinyl acetate in plastic production, cellulose acetate in photo�  graphic films and textiles (one of the first synthetic fibres, often called  simply acetate), and volatile organic esters as solvents.</p><p>acetic acid \o-'se-tik\ Most important carboxylic acid (CH 3 COOH). Pure  (�glacial�) acetic acid is a clear, syrupy, corrosive liquid that mixes readily  with water. Vinegar is its dilute solution, from fermentation and oxidation  (see oxidation-reduction) of natural products. Its salts and esters are  acetates. It occurs naturally as a metabolic intermediate in body fluids and  plant juices. Industrial production is either synthetic, from acetylene, or  biological, from ethanol. Industrial chemicals made from it are used in  printing and as plastics, photographic films, textiles, and solvents.</p><p>acetone Va-s3-,ton\ or dimethyl ketone Vdl-'me-thol-'ke-.tonX Sim�  plest and most important ketone (CH 3 COCH 3 ). It is a colourless, flam�  mable liquid, boiling at 133 �F (56.2 �C). Many fats, resins, and organic  materials dissolve easily in it, so it is used to make artificial fibres, explo�  sives, resins, paints, inks, cosmetics (including nail-polish remover), coat�  ings, and adhesives. Acetone is used as a chemical intermediate in  pharmaceuticals and many other compounds.</p><p>acetylcholine \3-,se-t 3 l-'ko-len\ Ester of choline and acetic acid, a neu�  rotransmitter active at many nerve synapses and at the motor end plate of  vertebrate voluntary muscles. It affects several of the body�s systems,  including the cardiovascular system (decreases heart rate and contraction  strength, dilates blood vessels), gastrointestinal system (increases peristal�  sis in the stomach and amplitude of digestive contractions), and urinary</p><p>system (decreases bladder capacity, increases voluntary voiding pressure).  It also affects the respiratory system and stimulates secretion by all glands  that receive parasympathetic nerve impulses (see autonomic nervous sys�  tem). It is important in memory and learning and is deficient in the brains  of those with late-stage Alzheimer disease.</p><p>acetylene or ethyne \'e-,thm\ Simplest alkyne, C 2 H 2 . A colourless,  flammable, explosive gas, it is used as a fuel in welding and cutting met�  als and as a raw material for many organic compounds and plastics. It is  produced by reaction of water with calcium carbide, passage of a hydro�  carbon through an electric arc, or partial combustion of methane. Decom�  posing it liberates heat; depending on degree of purity, it is also an  explosive. An acetylene torch reaches about 6,000 �F (3,300 �C), hotter  than combustion of any other known gas mixture. See also hydrocarbon.</p><p>Achaean Any member of an ancient Greek people identified in Homer  as those who, with the Danaoi and the Argeioi, attacked Troy. Some iden�  tify them with the Mycenaeans of the 14th�13th century bc; others say  that they arrived in the 12th-century Dorian invasions. They may have  held power only a few generations before being replaced by the Dorians.  Herodotus claims the later Achaeans of the northern Peloponnese (see  Achaean League) were descended from these earlier Achaeans.</p><p>Achaean League \o-'ke-3n\ 3rd-century bc confederation of towns of  Achaea, an area in the northern Peloponnese of ancient Greece. Twelve  cities had joined together by the 4th century bc to combat piracy, but they  disbanded after the death of Alexander the Great. Ten cities renewed the  league in 280 bc, later admitting non-Achaean cities to defend themselves  against Macedonia, then Sparta, and finally Rome. Rome dissolved the  league after defeating it in 146 bc. Later a smaller league was formed that  existed into the Roman imperial age.</p><p>Achaemenian \,a-k3-'me-ne-3n\ dynasty (559-330 bc) Early Per�  sian dynasty. It derives its name from Achaemenes, who is thought to have  lived in the early 7th century bc. From his son Teispes were descended  two lines of kings. The older line included Cyrus I, Cambyses I, Cyrus II  (the Great), and Cambyses II; the junior line began with Darius I and ended  with the death of Darius III after his defeat by Alexander the Great (330  bc). Its greatest rulers were Cyrus II (r. 559-c. 529 bc), who actually  established the Persian empire and from whose reign it is dated; Darius  I, who secured the borders from external threats; and Xerxes I, who com�  pleted many of Darius�s public works. At its height, the Achaemenian  Empire reached from Macedonia to northern India and from the Cauca�  sus Mountains to the Persian Gulf.

Concerned with emergent Africa  at its moments of crisis, he is acclaimed for depictions of the disorien�  tation accompanying the imposition of Western customs and values on  traditional African society. Things Fall Apart (1958) and Arrow of God  (1964) portray traditional Igbo life as it clashes with colonialism. No  Longer at Ease (1960), A Man of the People (1966), and Anthills of the  Savannah (1988) deal with corruption and other aspects of postcolonial  African life. Home and Exile (2000) is in part autobiographical, in part a  defense of Africa against Western distortions.</p><p>Achelous River V.a-ko-'lo-osX Longest river in Greece. It rises in the  Pindus Mountains and flows south 140 mi (220 km) to the Ionian Sea.  Hydroelectric dams harness its waters at Kastraki and Kremasta.

(20-25 cm) in length and flaked over its entire  surface. Other implements include cleavers, borers, knives, and choppers.  The name derives from the site near St.-Acheul, in northern France, where  such tools were first discovered. Acheulean industry was extremely long-  lived (1,500,000-110,000 years ago) and is associated with both Homo  erectus and archaic Homo sapiens.</p><p>Achilles \a -'ki-lez\ In Greek mythology, the bravest and strongest of the  Greek warriors in the Trojan War. Because his mother dipped him into  the River Styx, he was invulnerable except at the heel by which she held  him. During the war against Troy Achilles took 12 nearby cities, but after  a quarrel with Agamemnon he refused further service. He allowed his  beloved cousin Patroclus to fight in his armor, and when Hector slew  Patroclus, Achilles returned to battle, killed Hector, and dragged his body  around the walls of Troy. Homer mentions Achilles� funeral but not the  circumstances of his death; the later poet Arctinus relates that Paris killed  Achilles with an arrow guided by Apollo.</p><p>Achilles Painter (fl. 5th century bc) Greek vase painter, named for an  amphora decorated with a painting of Achilles and Briseis attributed to  him. He was active in Athens in the time of Pericles and was a contem�  porary of Phidias. His Achilles vase (c. 450 bc) is among the finest sur�  viving examples of red-figure pottery from the Classical period. He is also  known for his lekythoi (funerary vases with coloured figures on a white  background), which are regarded as the most reliable documentation of  monumental Greek paintings. Over 200 extant vase paintings are attrib�  uted to him.</p><p>Achinese X.a-cho-'nezX One of the main ethnic groups on the island of  Sumatra, Indon. In the 13th century the Achinese became the first people  in the archipelago to adopt Islam. After expelling the Portuguese in the  17th century, the sultanate of Acheh was dominant in northern Sumatra  until it was conquered by the Dutch in 1904 (see Achinese War). Now part  of the Indonesian republic, the Achinese are restive and are administered  within a special district. They trace their descent through both maternal  and paternal lines. Women have a high social position, and they do not  wear veils. The group numbers roughly 2.1 million.</p><p>Achinese War (1873 -1904) Armed conflict between The Netherlands  and the Muslim sultanate of Acheh in northern Sumatra. The Dutch con�  sidered the sultanate to be within their northern Sumatran sphere of influ�  ence and invaded it. Although the sultan capitulated, the Achinese people  engaged the Dutch in a prolonged and costly guerrilla war, which the  Dutch were able to win only by researching the area and devising a new  �castle strategy� that relied on fortified bases.</p><p>acid Any substance that in water solution tastes sour, changes the colour  of acid-base indicators (e.g., litmus), reacts with some metals (e.g., iron)  to yield hydrogen gas, reacts with bases to form salts, and promotes cer�  tain chemical reactions (e.g., acid catalysis). Acids contain one or more  hydrogen atoms that, in solution, dissociate as positively charged hydro�  gen ions. Inorganic, or mineral, acids include sulfuric acid, nitric acid,  hydrochloric acid, and phosphoric acid. Organic acids include carboxylic  acids, phenols, and sulfonic acids. Broader definitions of acids cover situ�  ations in which water is not present. See also acid-base theory.</p><p>acid and basic rocks Division of igneous rocks on the basis of their  silicate mineral content, these minerals usually being the most abundant in  such rocks. Rocks are described as acid, intermediate, basic, and ultraba-  sic, in order of decreasing silica content, because it was earlier thought  that silica is present in rock magmas in the form of silicic acid. In mod�</p><p>em usage the terms do not refer to acidity in the chemical sense. In gen�  eral, the gradation from acid to basic corresponds to an increase in colour  (i.e., light to dark).</p><p>acid-base theory Any of several theories that give rise to alternative  definitions of acids and bases. The original theory was based on Svante  Arrhenius�s electrolytic theory of solutions and involved the dissociation  of water into hydrogen and hydroxide ions. To explain the behaviour of  a chemical, particularly if water is not present, two other theories were  developed. The most widely accepted and useful is the Brpnsted-Lowry  definition (1923): An acid is a chemical that tends to lose a proton (H + ),  and a base is a chemical that tends to gain a proton. Another is the Lewis  definition (also 1923): An acid (see electrophile) is a chemical that can  accept an electron pair from a base (see nucleophile), which they share to  form a covalent bond. The three theories have superficial similarities but  subtle and important differences for certain applications.</p><p>acid rain Any precipitation, including snow, that contains a heavy con�  centration of sulfuric and nitric acids. This form of pollution is a serious  environmental problem in the large urban and industrial areas of North  America, Europe, and Asia. Automobiles, certain industrial operations,  and electric power plants that burn fossil fuels emit the gases sulfur diox�  ide and nitrogen oxide into the atmosphere, where they combine with  water vapour in clouds to form sulfuric and nitric acids. The highly acidic  precipitation from these clouds may contaminate lakes and streams, dam�  aging fish and other aquatic species; damage vegetation, including agri�  cultural crops and trees; and corrode the outsides of buildings and other  structures (historic monuments are especially vulnerable). Though usu�  ally most severe around large urban and industrial areas, acid precipita�  tion may also occur at great distances from the source of the pollutants.</p><p>Ackermann, Konrad Ernst (baptized Feb. 4, 1712, Schwerin,  Mecklenburg�d. Nov. 13, 1771, Hamburg) German actor-manager. After  training with a theatre company that specialized in German adaptations  of French plays, he led a troupe on tour throughout Europe in the 1750s.  He became known for domestic drama and for playing roles that com�  bined the comic and the sentimental. In 1765 he opened a theatre in Ham�  burg, considered the first German national theatre, and later turned its  management over to his stepson, Friedrich L. Schroder (1744-1816), who  brought Shakespeare to the German stage.

Acne  vulgaris, probably the most frequent chronic skin disorder, results from  an interplay of hereditary factors, hormones, and bacteria, beginning in  the teen years when overactive sebaceous glands are stimulated by high  levels of androgens. Its primary lesion, the blackhead, may be open or  closed; it consists of a plug of skin oil (sebum), cell debris, and micro�  organisms in a hair follicle. Acne has four grades of severity, with increas�  ing degrees of spread, inflammation, pustule formation, and scarring.  Methods of treatment vary from skin medication to antibiotics and hor�  mones; many cases eventually resolve spontaneously.</p><p>Acoma Va-ko-moX Indian pueblo, west-central New Mexico, U.S. It is  located on a reservation west of Albuquerque and is known as the �Sky  City.� Its people live in terraced dwellings made of stone and adobe atop  a sandstone butte 357 ft (109 m) high. Settled in the 10th century, it is  believed to be the oldest continuously inhabited place in the U.S. In 1540  Spanish explorer Francisco Vazquez de Coronado described it as the  strongest defensive position in the world.</p><p>Aconcagua X.a-kon-'ka-gwaX, Mount Mountain, western Argentina,  on the Chilean border. Located in the Andes Mountains at an elevation of  22,834 ft (6,960 m), it is widely considered the highest peak in the West�  ern Hemisphere. It is of volcanic origin but is not itself an active volcano.  The summit was first reached in 1897.</p><p>aconite X'a-ka-.nltX Any member of two genera of perennial herbaceous  plants of the buttercup family: Aconitum (monkshood or wolfsbane), con�  sisting of summer-flowering poisonous plants, and Eranthis (winter aco�  nite), consisting of spring-flowering ornamentals. The dried tuberous root  of A. napellus was formerly used as a sedative and a painkiller.</p><p>acorn Nut of the oak. Acorns are usually seated in or surrounded by a  woody cupule.

Gabriel da Costa (b. c. 1585,  Oporto, Port.�d. April 1640, Amsterdam, Neth.) Portuguese Jewish free�  thinker. Born into a Marrano family, he came to feel that there was no  salvation through the Roman Catholic church and converted to Judaism.  His mother and brother also converted, and he and his family fled to  Amsterdam. In 1616 he attacked rabbinic Judaism as nonbiblical and was  excommunicated. When he enlarged on his criticisms in 1623-24, deny�  ing the immortality of the soul, he was arrested and fined. He recanted  but was later excommunicated again. He recanted publicly in 1640, after  which he wrote a short autobiography. Example of a Human Life , and  shot himself.</p><p>acoustics \3-'ku-stiks\ Science of production, control, transmission,  reception, and effects of sound. Its principal branches are architectural,  environmental, musical, and engineering acoustics, and ultrasonics. Envi�  ronmental acoustics focuses on controlling noise produced by aircraft  engines, factories, construction machinery, and general traffic. Musical  acoustics deals with the design and use of musical instruments and how  musical sounds affect listeners. Engineering acoustics concerns sound  recording and reproduction systems. Ultrasonics deals with ultrasonic  waves, which have frequencies above the audible range, and their appli�  cations in industry and medicine.</p><p>acoustics, architectural Relationship between sound produced in a  space and its listeners, of particular concern in the design of concert halls  and auditoriums. Good acoustic design takes into account such issues as  reverberation time; sound absorption of the finish materials; echoes;  acoustic shadows; sound intimacy, texture, and blend; and external noise.  Architectural modifications (e.g., orchestral shells, canopies, and undu�  lating or angled ceilings and walls) may act as focusing elements to  improve sound quality.</p><p>acquired immunodeficiency syndrome See AIDS  Acre See 'Akko</p><p>acrobatics Art of jumping, tumbling, and balancing. The art is of  ancient origin; acrobats performed leaps, somersaults, and vaults at Egyp�  tian and Greek events. Acrobatic feats were featured in the commedia  dell'arte theatre in Europe and in jingxi (�Peking opera�) in China. The  later use of apparatuses such as poles, tightropes, and flying trapezes made  acrobatics a major attraction in circus performances. Its popularity  increased in the 20th century with such performers as the Flying Wallen-  das (see Karl Wallenda).</p><p>acromegaly V.a-kro-'me-go-leN Growth and metabolic disorder in which  the skeletal extremities enlarge when a pituitary gland tumor causes over�  production of growth hormone after maturity. It is often associated with  pituitary gigantism. Acromegaly is characterized by gradual enlargement of  hands and feet, exaggeration of facial features, skin thickening, and  enlargement of most internal organs, along with headaches, excessive  sweating, and high blood pressure. Acromegalic individuals are likely to  develop congestive heart failure, muscle weakness, joint pain, osteoporo�  sis, and often diabetes mellitus and visual problems, including blindness. If  treatment with surgery and/or radiation fails, then hormone therapy is used.  Treatment can cause hormone deficiency, necessitating hormone replace�  ment therapy; spontaneous events may also cause hormone deficiency.</p><p>acropolis (Greek: �city at the top�) Central, defensively oriented dis�  trict in ancient Greek cities, located on the highest ground and contain�  ing the chief municipal and religious buildings. The renowned Athens  Acropolis (5th century bc), atop a craggy walled hill, is home to four main  edifices�the Propylaea (see propylaeum), Parthenon, Erechtheum (Ionic  temple noted for its caryatid porch), and Temple of Athena Nike�all built  from white marble plentiful in the region. See photograph opposite.</p><p>acrostic Originally, a short verse composition, constructed so that one  or more sets of letters (such as the initial, middle, or final letters of the  lines), taken consecutively, form words. An acrostic in which the initial  letters form the alphabet is called an abecedarius. Ancient Greek and Latin  writers, medieval monks, and Renaissance poets are among those who  devised acrostics. Today the term is used for a type of word puzzle uti�  lizing the acrostic principle. A popular form is double acrostics, puzzles  constructed so that the middle or last, as well as initial, letters of lines  may form words.</p><p>acrylic compound Any of a class of synthetic plastics, resins, and  oils used to manufacture many products. By varying the starting reagents</p><p>(such as acrylic acid, C 3 H 4 0 2 , or acrylonitrile, C 3 H 3 N) and the process  of forming, a material may be produced that is hard and transparent, soft  and resilient, or a viscous liquid. Acrylic compounds are used to make  molded structural and optical parts, jewelry, adhesives, coating com�  pounds, and textile fibres. Lucite and Plexiglas are trademarks used for  glasslike acrylic materials.</p><p>acrylic \9-'kri-lik\ painting Painting executed in the medium of acrylic  resins�synthetic resins that dry rapidly, are water-soluble, and serve as  a vehicle for any pigment. Its effects may range from the transparent bril�  liance of watercolour to the density of oil paint. Acrylics are less affected  by heat and deterioration than oils. They were first used by artists in the  1940s but became popular with Pop artists when they were produced  commercially in the 1960s.</p><p>Act of Union See Act of Union (1707), Act of Union (1800)</p><p>Acta Latin "Acts" In ancient Rome, the daily minutes of public busi�  ness and a record of political and social events. Julius Caesar in 59 bc  ordered that the Senate�s daily doings ( acta diurna, commentaria Sena-  tus) be made public; Caesar Augustus later prohibited publication, though  the Senate�s acts continued to be recorded and could be read with special  permission. There were also public registers (acta diurna urbis, �daily  minutes of the city�) of the acts of the popular assemblies and the courts  as well as births, deaths, marriages, and divorces. These constituted a daily  gazette, a prototype of the modern newspaper.</p><p>ACTH in full adrenocorticotropic \3- , dre-no- l kor-ti-ko- , tro-pik\  hormone Polypeptide hormone made in the pituitary gland. It regulates  the activity of part of the adrenal cortex (see adrenal glands), the produc�  tion site of important steroid hormones that affect electrolyte and water  balance and the metabolism of fats, carbohydrates, and proteins. ACTH is  found in vertebrates (except jawless fishes); in mammals it contains 39  amino acids. Overproduction of ACTH is one cause of Cushing syndrome.</p><p>actin One of two proteins responsible for contraction of muscle cells and  the motility of other cells. It occurs as a monomer, G-actin, a globular  protein, and in living cells as a polymer, F-actin, which resembles two  strings of beads twisted around each other into thin filaments. The fila�  ments occur in regular structures, alternated and interwoven with thick  filaments that contain myosin, the other major muscle protein. The thick  and thin filaments slide past each other, under the control of calcium ions,  resulting in contraction (shortening) and relaxation (lengthening) of the  muscle cells.</p><p>acting Art of representing a character on a stage or before a camera by  means of movement, gesture, and intonation. Acting in the Western tra�  dition originated in Greece in the 6th century bc; the tragedian Thespis is  traditionally regarded as founder of the profession. Aristotle defined act�  ing as �the right management of the voice to express various emotions�  and declared it a natural gift that he doubted could be taught. Acting  declined as an art in the Middle Ages, when Christian liturgical drama was  performed by craft guilds and amateurs. Modern professional acting  emerged in the 16th century with Italy�s commedia dell'arte troupes.

Not until the 18th cen�  tury, however, was acting considered a profession to be taken seriously,  through the efforts in England of the actor-manager David Garrick and the  talents of actors such as Sarah Siddons, Edmund Kean, and Henry Irving.  Modern acting styles have been influenced by Konstantin Stanislavsky�s  emphasis on the actor�s identification with his role and by Bertolt Brecht�s  insistence on the objectivity and discipline of the actor. The Stanislavsky  method was adopted in the U.S. by Lee Strasberg and Stella Adler (1901�  92) and is the basis of most contemporary training, which features the  cultivation of emotional and sense memory, physical and vocal training,  and improvisation.</p><p>actinide \ l ak-t9-,nld\ Any of the series of 15 consecutive chemical ele�  ments in the periodic table from actinium to lawrencium (atomic numbers  89-103). All are radioactive heavy metals; and only the first four  (actinium, thorium, protactinium, and uranium) occur in nature in appre�  ciable quantities. The other 11 (the transuranium elements) are unstable and  are produced only artificially. Actinides are transition elements, so their  atoms have similar configurations and similar physical and chemical  behaviour; the most usual valences are 3 and 4.</p><p>actinolite \ak- , ti-n 3 l-,It\ Colourless to green amphibole mineral, darken�  ing with increased iron content from green to black. It has a prismatic and  splintery texture and is abundant in regionally metamorphosed (see meta�  morphism) rocks such as schists. Actinolite has a monoclinic crystal struc�  ture, and it may alter to chlorite. See also asbestos.</p><p>actinomycete \,ak-ti-no-'mI-set\ Any of a group of generally low-  oxygen-utilizing bacteria identified by a branching growth pattern that  results in large threadlike structures. The filaments may break apart to  form rods or spheroidal shapes. Some actinomycetes can form spores.  Many species occur in soil and are harmless to animals and higher plants;  others are important disease-causing agents. For diagnostic purposes in  human infections, the presence of sulfur granules is used.</p><p>Action Francaise \ak-se-'o n -fra n -'sez\ (�French Action�) Influential  right-wing antirepublican group in early 20th-century France, whose  views were promoted in a newspaper of the same name. The Action  Francaise movement, led by Charles Maurras, espoused the antiparlia�  mentarian, anti-Semitic, and strongly nationalist views inspired by the  Alfred Dreyfus Affair. The movement peaked after World War I, when  nationalist feeling was strong. It was denounced by the papacy in 1926,  and ceased to exist after World War II because of its association with the  collaborationist Vichy government (see Vichy France).</p><p>action painting Direct, instinctual, dynamic style of painting that  involves the spontaneous application of vigorous, sweeping brush strokes  and the chance effects of dripping and spilling paint onto the canvas. The  term characterizes the work of Jackson Pollock, Willem de Kooning, and  Franz Kune. The �automatic� techniques developed in Europe by the Sur�  realists in the 1920s and �30s had great influence on U.S. artists, who  regarded a picture not merely as a finished product but as a record of the  process of its creation. It was a major force in Abstract Expressionism in  the 1950s. See also automatism, Tachism.</p><p>action potential Brief (about one-thousandth of a second) reversal of  electric polarization of the membrane of a nerve or muscle cell. Stimu�  lation of the cell by certain chemicals or by sensory receptor cells causes  depolarization of the membrane, permitting an impulse to move along the  nerve fibre (in nerve cells) or causing the cell to contract (in muscle cells).</p><p>Actium Vak-she-omV Battle of (31 bc) Naval battle off Acarnania,  Greece, between Octavian (later Augustus) and Mark Antony. With 500  ships and 70,000 infantry, Antony camped at Actium, between the Ionian  Sea and the Ambracian Gulf. Octavian, with 400 ships and 80,000 infan�  try, cut Antony�s line of communication from the north. Desertion by  allies and a lack of supplies forced Antony to act. Outmaneuvered on land,  he followed Cleopatra�s advice to attack Octavian at sea. Antony�s larger  fleet included his own and Cleopatra�s ships. In the heat of battle Cleo�  patra fled with her galleys, and Antony followed with a few ships. His  fleet surrendered immediately, his army a week later. Octavian�s victory  left him undisputed ruler of the Roman world.</p><p>activation energy Minimum amount of energy (heat, electromagnetic  radiation, or electrical energy) required to activate atoms or molecules to a  condition in which it is equally likely that they will undergo chemical  reaction or transport as it is that they will return to their original state.  Chemists posit a transition state between the initial conditions and the</p><p>product conditions and theorize that the activation energy is the amount  of energy required to boost the initial materials �uphill� to the transition  state; the reaction then proceeds �downhill� to form the product materi�  als. Catalysts (including enzymes) lower the activation energy by altering  the transition state. Activation energies are determined by experiments  that measure them as the constant of proportionality in the equation  describing the dependence of reaction rate on temperature, proposed by  Svante Arrhenius. See also entropy, heat of reaction.</p><p>active galactic nucleus Small region at the centre of a galaxy that  emits a prodigious amount of energy in the form of radio, optical. X-ray,  or gamma radiation or high-speed particle jets. Many classes of �active  galaxies� have been identified; they appear similar in many respects to  quasars. Astronomers suspect that the observed energy is generated as  matter accretes onto a supermassive black hole with a mass millions or  even billions of times that of the Sun. The accreting matter can outshine  the rest of the galaxy as it is heated in very high-speed collisions outside  the black hole�s event horizon. It is believed that many galaxies harbour  these central black holes and that they might have been quasars in their  early history, although they now appear to be dormant unless orbiting  matter is accreting onto the black hole.</p><p>activity coefficient Number expressing the ratio of a substance�s  chemical activity to its molar concentration (see mole). The measured  concentration of a substance may not be an accurate indicator of its chemi�  cal effectiveness as represented by the equation for a particular reaction;  in such cases, the activity is calculated by multiplying the concentration  by the activity coefficient. In solutions, the activity coefficient is a mea�  sure of how much the solution differs from an ideal solution.</p><p>Acton (of Aldenham), John Emerich Edward Dahlberg  Acton, 1st Baron (b. Jan.10, 1834, Naples, Kingdom of Naples�d.  June 19, 1902, Tegernsee, Bavaria, German Empire) English historian. He  served in the House of Commons (1859-65). Editor of the Roman Catholic  monthly The Rambler (1859-64), he resigned because of papal criticism of  his scientific approach to history. An adviser to William E. Gladstone from  1865, he was raised to the peerage in 1869. In 1895 he was appointed  Regius Professor of Modern History at the University of Cambridge. He  later coordinated the massive publication project of The Cambridge Mod�  ern History. A critic of nationalism, he coined the familial - aphorism  �Power tends to corrupt, and absolute power corrupts absolutely.�</p><p>actor-manager system Method of theatrical production prevalent  in 19th-century England and the U.S. In this system, an actor formed a  theatre company, chose the plays he wanted to produce, played the lead�  ing roles in them, and managed the company�s business arrangements.  The first actor-managers emerged in the 17th century, and in the 18th cen�  tury actor-managers such as Colley Cibber and David Garrick gained promi�  nence. The system produced high performance standards, typified by  19th-century figures such as William Macready, Henry Irving, and Herbert  Tree. It waned as actor-managers were replaced first by stage managers  and later by directors.</p><p>Actors Studio Professional actors� workshop based in New York City.  Founded in 1947 by the directors Cheryl Crawford, Eua Kazan, and Rob�  ert Lewis as a leading centre of the Stanislavsky method, it was directed  by Lee Strasberg from 1948 to 1982. In 1962 it launched a company, and  a workshop was established in Los Angeles in 1966. Actors work together  without the pressures of commercial production. Membership is by invi�  tation; six or seven new members are chosen yearly from 1,000 auditions.  Members have included Marlon Brando, AAarilyn Monroe, Paul Newman,  and Robert De Niro.</p><p>actuary One who calculates insurance risks and premiums. Actuaries  compute the probability of the occurrence of such events as birth, mar�  riage, illness, accidents, and death. They also evaluate the hazards of  property damage or loss and the legal liability for the safety and well�  being of others.

Though often referred to by its Japanese name, shiatsu, it  originated in China thousands of years ago. A single point may be pressed  to relieve a specific symptom or condition, or a series of points can be  worked on to promote overall well-being. Some studies suggest that acu�  pressure can be effective for certain health problems, including nausea,  pain, and stroke-related weakness. Risks are minimal with cautious use.  See also acupuncture.</p><p>acupuncture Medical technique in which needles are inserted into the  skin and underlying tissues, devised in China before 2500 bc. One or more  small metal needles are inserted at precise points along 12 meridians  (pathways) in the body, through which the vital life force (qi) is believed  to flow, in order to restore yin-yang balance and treat disease caused by  yin-yang imbalance. Acupuncture appears to relieve pain and is used as  an anesthetic for surgery. Theories to explain its effects include stimula�  tion of release of natural opiates, blockage of pain-signal transmission,  and a placebo effect.

By 1533 Adal, now led by Ahmed Gran,  succeeded in gaining control of most of central Ethiopia. Gran was killed  in battle in 1543, and the Oromo invasions of the later 16th century ended  Adal�s power.</p><p>Adalbert Yad-^-.bartV, Saint orig. Vojtech (b. 956, Libice?,  Bohemia�d. April 23, 997, near Gdansk, Pol.; feast day April 23) Czech  prelate. Descended from the princes of Bohemia, he was trained in the�  ology at Magdeburg. Elected the first native bishop of Prague in 982, he  promoted the political aims of the Bohemian prince by extending the  influence of the church beyond the Czech kingdom. Failing to convert his  people, he retired in 988 to a monastery near Rome. On papal orders, he  returned in 992 to find little change. Disillusioned, he left Bohemia in 994  to become a missionary along the Baltic coast, where he was martyred in  997. An account of his life was written by his friend and disciple St. Bruno  of Querfurt. He was recognized as a saint soon after his death.</p><p>Adam, Robert (b. July 3, 1728, Kirkcaldy, Fife, Scot.�d. March 3,  1792, London, Eng.) Scottish architect and designer. Son of the architect  William Adam, he apprenticed in his father�s offices. He traveled in  Europe in 1754-58, studying architectural theory and Roman ruins. On  his return to London, he and his brother James (1732-94) developed an  essentially decorative style�known as the Adam style�that was marked  by a new lightness and freedom in the use of the Classical elements of  architecture. This style is most remembered for its application in interi�  ors, which were characterized by contrasting room shapes and delicate  Classical ornaments. Robert Adam�s executed works, mainly remodeled  interiors and exteriors of private houses, include Osterley Park (1761-80)  in Middlesex and Kedleston Hall (c. 1765-70) in Derbyshire. Other works  include the Adelphi development in London (1768-72) and the Univer�  sity of Edinburgh (1789). He was also a leading furniture designer; his</p><p>style, popularized by designer George Hepplewhite, was meant to harmo�  nize with his interior architecture down to the last detail.</p><p>Adam and Eve In the Judeo-Christian and Islamic traditions, the par�  ents of the human race. Genesis gives two versions of their creation. In  the first, God creates �male and female in his own image� on the sixth  day. In the second, Adam is placed in the Garden of Eden, and Eve is later  created from his rib to ease his loneliness. For succumbing to temptation  and eating the fruit of the forbidden tree of knowledge of good and evil,  God banished them from Eden, and they and their descendants were  forced to live lives of hardship. Cain and Abel were their children. Chris�  tian theologians developed the doctrine of original sin based on the story  of their transgression; in contrast, the Quran teaches that Adam�s sin was  his alone and did not make all people sinners.</p><p>Adamawa \,a-da-'ma-wa\ Traditional emirate centered in what is now  Adamawa state, eastern Nigeria. It was founded by Modibbo Adama in  the early 19th century. He moved the capital several times before finally  settling it in 1841 in Yola. The British Royal Niger Company established  trading posts there; when the emir tried to force them out in 1901, they  captured the town. Adamawa was partitioned in 1901 between British  Northern Nigeria and German Kamerun (Cameroon). In 1919 the Cam�  eroon portion was divided between the French and the British. The emir�  ate�s territories eventually came to form almost all of northern Cameroon  and part of eastern Nigeria.</p><p>Adamawa-Ubangi X.ad-o-'ma-wo-ii-'baq-geV languages formerly  Adamawa-Eastern languages Branch of the huge Niger-Congo  language family. Adamawa-Ubangi languages are spoken in eastern Nige�  ria, northern Cameroon, southwestern Chad, and western Central African  Republic. The branch has two divisions, Adamawa in the west and Ubangi  in the east. The Adamawa group comprises 80 languages, the least-studied  languages in the Niger-Congo family. Nearly all have fewer than 100,000  speakers. The Ubangi group includes 40 languages and extends across a  much broader region, from northern Cameroon across the Central Africa  Republic to adjacent parts of southern Sudan and northern Congo (Kin�  shasa). Ubangi languages with more than a million speakers include those  of the Banda, Gbaya, Ngbaka, and Zande peoples. Sango, a restructured  form of one or more languages of the Ngbandi group of Ubangi, has  become a lingua franca of the Central African Republic.</p><p>Adamov Xo-'da-movV Arthur (b. Aug. 23, 1908, Kislovodsk,  Russia�d. March 16, 1970, Paris, France) Russian-born French play�  wright. He settled in Paris in 1924, and his first major work, written after  suffering a nervous breakdown, was his autobiography, The Confession  (1938-43). Influenced by August Strindberg and Franz Kafka, he began  writing plays in 1947. Professor Taranne (1953) and Ping-Pong (1955)  expressed a view of life�s meaninglessness that was characteristic of the  Theatre of the Absurd. In Paolo Paoli (1957) and later plays, he abandoned  Absurdism for radical political theatre influenced by Bertolt Brecht.

She was  the daughter of a Congregational minister. Educated entirely at home, she  became an avid reader of history. She married John Adams in 1764 and  raised four children, including John Quincy Adams, in Quincy, Mass. In  1774 she began a prolific correspondence with her husband, who was  attending the Continental Congress in Philadelphia; she described daily  life and discussed public affairs during the American Revolution with wit  and political acuity. She continued her letters to family and friends while  in Europe (1784-88) and Washington, D.C. (1789-1801), during her hus�  band�s diplomatic and presidential careers. She was considered an influ�  ential adviser to him.</p><p>Adams, Ansel (b. Feb. 20, 1902, San Francisco, Calif., U.S.�d. April  22, 1984, Carmel, Calif.) U.S. photographer. In 1927 he published Parme-  lian Prints of the High Sierras, photographs that imitated Impressionist  painting by suppressing detail in favour of soft, misty effects achieved in  the darkroom. Adams was known for his dramatic images of mountain  landscapes. He became one of the outstanding technicians in the history  of photography; Making a Photograph (1935) was the first of his many  books on photographic technique. He worked consistently to foster pub�  lic awareness of photography as a fine art. In 1940 he helped organize the  first public collection of photographs, at the Museum of Modern Art, and  in 1946 he established, at the California School of Fine Arts, the first aca�  demic photography department.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Adams &#x25BA; Adamson I 15</p><p>Adams, Charles Francis (b.

The son of John Quincy Adams  and the grandson of John Adams, he  served in the Massachusetts legisla�  ture and edited a Whig journal. He  helped form the antislavery Free-Soil  Party and in 1848 was chosen its can�  didate for U.S. vice president.

Elected to the British  House of Commons in 1983, he refused to take the oath of allegiance and  never took his seat. In 1991, as Sinn Fein�s president (from 1983), he  began to shift its strategy toward negotiation; his efforts led to indirect  talks with the British government and a 1993 agreement (the Downing  Street Declaration) by the British and Irish prime ministers to consider  the future of Northern Ireland. He was credited with the IRA�s 1994  cease-fire announcement and was pivotal in winning support for the Good  Friday Agreement (1998), which led to the creation of a power-sharing  assembly in Northern Ireland.</p><p>Adams, Henry (Brooks) (b. Feb. 16, 1838, Boston, Mass., U.S.�d.  March 27, 1918, Washington, D.C.) U.S. historian and man of letters. A  product of Boston�s elite Brahmin class and a descendant of two presi�  dents, he was infused with disgust for American politics of his time. As  a young newspaper correspondent and editor, he called for social and  political reforms, but he later became disillusioned with a world he char�  acterized as devoid of principle. That loss of faith was reflected in his  novel Democracy (1880). His study of U.S. democracy culminated in his  nine-volume History of the United States of America (1889-91), which  received immediate acclaim. In Mont-Saint-Michel and Chartres (1913)  he described the medieval worldview as reflected in its architecture. The  Education of Henry Adams (1918), his best-known work and one of the  outstanding autobiographies of Western literature, traced his confronta�  tions with the uncertainties of the 20th century.</p><p>Adams, John (b. Oct. 30, 1735, Braintree, Mass.�d. July 4, 1826,  Quincy, Mass., U.S.) U.S. politician,  first vice president (1789-97) and  second president (1797-1801) of the  U.S. After graduating from Harvard  College in 1755, he practiced law in  Boston. In 1764 he married Abigail  Smith (see Abigail Adams). Active in  the American independence move�  ment, he was elected to the Massa�  chusetts legislature and served as a  delegate to the Continental Congress  (1774-78), where he was appointed  to a committee with Thomas Jefferson  and others to draft the Declaration of  Independence. In 1776-78 he was  appointed to many congressional  committees, including one to create  a navy and another to review foreign  affairs. He served as a diplomat in  France, the Netherlands, and  England (1778�88). In the first U.S.  presidential election, he received the  second largest number of votes and became vice president under George  Washington. Adams�s term as president was marked by controversy over</p><p>his signing of the Alien and Sedition Acts in 1798 and by his alliance with  the conservative Federalist Party. In 1800 he was defeated for reelection  by Jefferson and retired to live a secluded life in Massachusetts. In 1812  he overcame his bitterness toward Jefferson, with whom he began an illu�  minating correspondence. Both men died on July 4, 1826, the Declara�  tion�s 50th anniversary. John Quincy Adams was his son.</p><p>Adams, John (Coolidge) (b. Feb. 15, 1947, Worcester, Mass., U.S.)  U.S. composer. After studying at Harvard University he taught at the San  Francisco Conservatory and conducted widely. His compositions, initially  strongly influenced by minimalism, became tempered by expressive ele�  ments. His Nixon in China (1987) and The Death of Klinghoffer (1991)  are two of the best-known operas of the late 20th century. Other celebrated  works include Harmonium (1980), Grand Pianola Music (1982), and  Harmonielehre (1984-85).</p><p>Adams, John Quincy (b. July 11, 1767, Braintree, Mass.�d. Feb.  23, 1848, Washington, D.C., U.S.) Sixth president of the U.S. (1825-29).  He was the eldest son of John Adams, second president of the U.S., and  Abigail Adams. He accompanied his father to Europe on diplomatic mis�  sions (1778-80) and was later appointed U.S. minister to the Netherlands  (1794) and to Prussia (1797). In 1801 he returned to Massachusetts and  served in the U.S. Senate (1803-08). Resuming his diplomatic service, he  became U.S. minister to Russia (1809-11) and to Britain (1815-17).  Appointed secretary of state (1817-24), he was instrumental in acquiring  Florida from Spain and in drafting the Monroe Doctrine. He ran for the  presidency in 1824 against three other candidates; none received a major�  ity of the electoral votes, though Andrew Jackson received a plurality. By  constitutional design, the selection of the president went to the House of  Representatives, where Adams was elected after receiving crucial support  from Henry Clay, who had finished third in the initial balloting. He  appointed Clay secretary of state, which further angered Jackson. Adams�s  presidency was unsuccessful; when he ran for reelection, Jackson defeated  him. In 1830 he was elected to the House, where he served until his death.  He was outspoken in his opposition to slavery; in 1839 he proposed a  constitutional amendment forbidding slavery in any new state admitted to  the Union. Southern congressmen prevented discussion of antislavery  petitions by passing gag rules (repealed in 1844 as a result of Adams�s  persistence). In 1841 he successfully defended the slaves in the Amistad  mutiny case.</p><p>Adams, Samuel (b. Sept. 27, 1722, Boston, Mass.�d. Oct. 2, 1803,  Boston, Mass., U.S.) American Revolutionary leader. A cousin of John  Adams, he graduated from Harvard College in 1740 and briefly practiced  law. He became a strong opponent of British taxation measures and orga�  nized resistance to the Stamp Act. He was a member of the state legisla�  ture (1765-74), and in 1772 he helped found the Committees of  Correspondence. He influenced reaction to the Tea Act of 1773, organized  the Boston Tea Party, and led opposition to the Intolerable Acts. A delegate  to the Continental Congress (1774-81), he continued to call for separa�  tion from Britain and signed the Declaration of Independence.

Using spectroscopy, he investigated sunspots and the rotation of  the Sun, the velocities and distances of thousands of stars, and planetary  atmospheres. In 1904 he joined the original staff of Mount Wilson Obser�  vatory, where he served as director (1923-46). He took an important part  in planning the 200-in.

During a  trip to Europe in 1887-88 she visited the Toynbee Hall settlement house  in London, which sparked her interest in social reform. Determined to  create something like Toynbee Hall in the U.S., in 1889 she cofounded  Hull House in Chicago, one of the first settlement houses in North  America to provide practical services and educational opportunities for  the poor. She subsequently championed social reforms such as juvenile-  court law, justice for immigrants and African Americans, worker�s rights  and compensation, and women�s suffrage. In 1910 she became the first</p><p>female president of the National Conference of Social Work. An ardent  pacifist, she served in 1915 as chair of the International Congress of  Women and helped form the Women�s International League for Peace and  Freedom and the American Civil Liberties Union.

Adler advanced the theory of the inferiority complex to explain cases  of psychopathology; Adlerian psychotherapy sought to direct patients  emotionally disabled by inferiority feelings toward maturity, common  sense, and social usefulness. He established the first child guidance clinic  in 1921 in Vienna. He taught in the U.S. (at Columbia University and the  Long Island College of Medicine) from 1927 until his death. His works  include Understanding Human Nature (1927) and What Life Should Mean  to You (1931).</p><p>Adler, Guido (b. Nov. 1, 1855, Eibenschiitz, Moravia, Austrian  Empire�d. Feb. 15, 1941, Vienna, Austria) Austrian musicologist. After  studying music theory and composition at the Vienna Conservatory, he  studied music history at the University of Vienna under Eduard Hanslick  (1825-1904), whom he succeeded as professor. He worked with Philipp  Spitta (1841-94) and Friedrich Chrysander in founding musicology as an  academic discipline. Among his distinguished students were Karl Geir-  inger (1899-1989), Knud Jeppesen (1892-1974), Anton Webern, and  Egon Wellesz (1885-1974).</p><p>Adler, Larry orig. Lawrence Cecil Adler (b. Feb. 10, 1914, Bal�  timore, Md., U.S.�d. Aug. 7, 2001, London, Eng.) U.S. harmonica  player. Though he was initially unable to read music, he learned classical  compositions by ear and became the first person to perform concert music  on the harmonica. His musicality attracted many composers to write espe�  cially for him, including Darius Milhaud and Ralph Vaughan Williams.  Accused of communist sympathies and blacklisted in the early 1950s, he  was unable to find work in the U.S. and took up residence in England.</p><p>Adler, Mortimer J(erome) (b. Dec. 28, 1902, New York, N.Y.,  U.S.�d. June 28, 2001, San Mateo, Calif.) U.S. philosopher, educator,  and editor. He earned a doctorate in philosophy from Columbia Univer�  sity (1928) and taught philosophy of law from 1930 at the University of  Chicago, where with Robert M. Hutchins he promoted the idea of liberal  education through regular discussions of the great books. Together they  edited the 54-volume Great Books of the Western World (1952); for Ency-  CLOPAlDIA Britannica, Inc., they edited an annual, The Great Ideas Today  (from 1961), and the 10-volume Gateway to the Great Books (1963). In  1969 Adler became director of planning for the 15th edition of Encyclo-  pcedia Britannica , published in 1974. His many books include How to  Read a Book (1940), How to Think About God (1980), Six Great Ideas  (1981), and Ten Philosophical Mistakes (1985).</p><p>administrative law Law regulating the powers, procedures, and acts  of public administration. It applies to all public officials and public agen�  cies. As distinguished from legislative and judicial authority, administra�  tive authority entails the power to issue rules and regulations based on  statutes, grant licenses and permits to facilitate the conduct of govern�  ment business, initiate investigations of and provide remedies for com�  plaints or problems, and issue orders directing parties to conform to  governing statutes or rules. An administrative-law judge is a government  official with quasi-judicial powers, including the authority to conduct  hearings, make findings of fact, and recommend resolution of disputes  concerning the agency�s actions.</p><p>admiral butterfly Any of several species of butterflies (family Nymph-  alidae) that are colourful, fast-flying, and much prized by collectors. The  migratory red admiral ( Vanessa atalanta ), widespread in Europe, Scandi�  navia, North America, and North Africa, feeds on stinging nettles.

An extension of the Bismarck Archipelago comprising about 40  islands, the Admiralty Islands lie about 190 mi (300 km) north of the  mainland of Papua New Guinea in the South Pacific Ocean. Most of the  land area of the islands is contained in Manus Island, which is the site of  Lorengau, the islands� principal settlement. First sighted by the Dutch  explorer Willem Schouten in 1616, it was named by the British captain  Philip Carteret in 1767. Subsequently ruled by the Germans, Australians,  and Japanese, the islands were made part of the UN Trust Territory of</p><p>New Guinea in 1946.

As a building material, adobe  dates back thousands of years and is found in many parts of the world.  Molds for shaping the bricks were brought to the New World by the  Spanish. Excellent insulating properties make adobe an ideal material for  both dwellings and ovens; home interiors retain heat in winter and stay  cool in summer. The adobe buildings at Taos, N.M., are typical of Native  American pueblo dwellings.</p><p>adolescence Period of life from puberty to adulthood (roughly ages  12-20) characterized by marked physiological changes, development of  sexual feelings, efforts toward the construction of identity, and a progres�  sion from concrete to abstract thought. Adolescence is sometimes viewed  as a transitional state, during which youths begin to separate themselves  from their parents but still lack a clearly defined role in society. It is gen�  erally regarded as an emotionally intense and often stressful period.</p><p>Adonis \3-'da-nos\ In Greek mythology, a youth of remarkable beauty,  the favorite of Aphrodite. As a child he was put in the care of Persephone,  who refused to allow him to return from the underworld. Zeus ruled that  he should spend a third of the year with Persephone, a third with Aph�  rodite, and a third on his own. He became a hunter and was killed by a  boar. In answer to Aphrodite�s pleas, Zeus allowed him to spend half the  year with her and half in the underworld. Mythically, Adonis represents  the cycle of death and resurrection in winter and spring. He is identified  with the Babylonian god Tammuz.</p><p>adoption Act of transferring parental rights and duties to someone other  than the adopted person�s biological parents. The practice is ancient and  occurs in all cultures. Traditionally, its goal was to continue the male line  for the purposes of inheritance and succession; most adoptees were male  (and sometimes adult). Contemporary laws and practices aim to promote  child welfare and the development of families. In the latter part of the  20th century, there was a relaxation of traditional restrictions on age dif�  ferences between adoptive parents and children, on the parents� minimum  income level, on the mother�s employment outside the home, and on  placements across religious and ethnic lines. Single-parent adoptions and  adoptions by same-sex couples also became more acceptable. Beginning  in the 1970s, a growing adoptees-rights movement in the United States  called for the repeal of confidentiality laws in most states that prevented  adoptees as adults from viewing their adoption records, including their  original birth certificates.</p><p>Adorno Xa-'dor-noV Theodor (Wiesengrund) (b. Sept. 11, 1903,  Frankfurt am Main, Ger.�d. Aug. 6, 1969, Visp, Switz.) German phi�  losopher. He immigrated to England in 1934 to escape Nazism. He lived  for 10 years in the U.S. (1938-48) before returning to Frankfurt, where  he taught and headed the Frankfurt Institute for Social Research (see  Frankfurt School). He is notable for his books and essays on philosophy,  literature, psychology, sociology, and music (which he studied with Alban  Berg). For Adorno, the great task of modernist music, literature, and art  was to keep alive the possible social alternatives to capitalism, which phi�  losophy and political theory could no longer imagine. His works include  Dialectic of Enlightenment (1947; with Max Horkheimer), Minima Mora-  lia (1951), and Notes to Literature (4 vols., 1958-74).</p><p>Adour \3-'dur\ River River, southwestern France.

In  humans, each gland weighs about 0.15 oz (4.5 g) and consists of an inner  medulla, which produces the catecholamine hormones epinephrine and  norepinephrine, and an outer cortex (about 90% of the gland), which  secretes the steroid hormones aldosterone, cortisol, and androgens (the last  two in response to ACTH from the pituitary gland). Diseases of the adre�  nal glands include pheochromocytoma (a tumour of the medulla) and the  cortical disorders Addison disease, adrenal hypertrophy, Cushing syndrome,  and primary aldosteronism.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>adrenaline &#x25BA; advertising I 19</p><p>adrenaline See epinephrine</p><p>Adrian \'a-dre-3n\ IV orig. Nicholas Breakspear (b. 1100?,  Abbot�s Langley, near St. Albans, Hertfordshire, Eng.�d. Sept. 1, 1159,  Anagni, near Rome [Italy]) Pope (1154-59), the only Englishman ever to  hold the office. He served in France and Italy before a successful mission  to Scandinavia led to his election as pope. Adrian crowned Frederick I Bar-  barossa emperor in 1155, after Frederick had turned over Arnold of Bres�  cia, leader of a revolt in Rome. The relationship quickly soured, however,  as a result of Adrian�s policy toward the Normans of southern Italy and  his assertion that Frederick had received the imperial crown as a benefice.  His controversial bull Laudabiliter supposedly gave Ireland to Henry II of  England, a claim that was later refuted. Adrian�s refusal to recognize the  king of Sicily, William I, stirred revolt in the Campania.</p><p>Adrian, Edgar Douglas later 1st Baron Adrian of Cambridge</p><p>(b. Nov. 30, 1889, London, Eng.�d. Aug. 4, 1977, London) British elec�  trophysiologist. He amplified electrical potential variations in nerve  impulses from sense organs to record ever smaller changes, eventually  recording impulses from single sensory endings and motor nerve fibres.  His work clarified the physical basis of sensation and the mechanism of  muscular control. Adrian�s later studies of brain electrical activity  included investigations into epilepsy and the location of cerebral lesions.  He shared a 1932 Nobel Prize with Charles Sherrington.</p><p>Adrianople, Battle of or Battle of Hadrianopolis (ad 378)  Battle fought in what is now Edirne, Tur., that marked the beginning of  serious Germanic incursions into Roman territory. It pitted the Roman  army under the emperor Valens against the horsemen of the Visigoths,  Ostrogoths, and other Germanic tribes. The Roman army was annihilated  and Valens died on the battlefield. His successor, Theodosius I, and the  Goths agreed in 382 that the Goths would help with imperial defenses in  exchange for food subsidies. The treaty set the pattern for later barbarian  intrusions.</p><p>Adrianople, Treaty of see Treaty of Edirne</p><p>Adriatic Sea Arm of the Mediterranean Sea, lying between Italy and  the Balkan Peninsula. It is about 500 mi (800 km) long, with an average  width of 110 mi (175 km), a maximum depth of 4,035 ft (1,324 m), and  an area of 50,590 sq mi (131,050 sq km). The Italian coast is relatively  straight and continuous, having no islands, but the Balkan coast is full of  islands, generally running parallel to the shore. The Strait of Otranto at  its southeasterly limit links it with the Ionian Sea.</p><p>adsorption Capability of a solid substance (adsorbent) to attract to its  surface molecules of a gas or solution (adsorbate) with which it is in con�  tact. Physical adsorption depends on van der Waals forces of attraction  between molecules and resembles condensation of liquids. In chemical  adsorption (often called chemisorption; see catalysis), the gas is held to  the surface by chemical forces specific to the chemicals involved, and  formation of the bond may require an activation energy.</p><p>'Adullam Vo-'dol-omN Ancient village, Israel, about 15 mi (24 km) south�  west of Jerusalem. A cave in its vicinity was from early times a place of  refuge; it is mentioned several times in the Bible (e.g., as the place where  David hid from Saul).</p><p>adult education See continuing education</p><p>adultery Sexual relations between a married person and someone other  than his or her spouse. Prohibitions against adultery are found in virtu�  ally every society; Jewish, Christian, and Islamic traditions all condemn  it, and in some Islamic countries it is still punishable by death. Attitudes  toward adultery in different cultures have varied widely. Under the Code  of Hammurabi (18th century bc) in Babylonia it was punishable by death  by drowning, and in ancient Rome an offending woman could be killed,  though men were not severely punished. In western Europe and North  America, adultery by either spouse is a ground for divorce, though in the  U.S. the shift to no-fault divorce significantly reduced the importance of  adultery as an element in divorce proceedings. The spread of Western  ideas of equality in marriage has resulted in pressure for equal marital  rights for women in traditional African and Southeast Asian societies.</p><p>adulthood Period in the human life span in which full physical and  intellectual maturity have been attained. Adulthood is commonly thought  of as beginning at age 20 or 21. It includes middle age (commencing  around age 40) and old age (from about age 60). Physically, it is char�  acterized by the peaking (around age 30) and gradual decline of bodily</p><p>functioning; the postpeak phase includes diminished acuity of the senses,  reduction in muscular and skeletal mass, buildup of cholesterol in the  arteries, weakening of the heart muscle, and diminished production of  hormones. Some slowing in the rate of central-nervous-system process�  ing also begins with middle age, but it is generally compensated for by  an increased capacity to retain practical information and apply accumu�  lated cultural knowledge. In old age, most individuals experience a sig�  nificant decline in physical capacity, and many eventually also suffer  impaired mental function.</p><p>Advaita \3d-'vl-t3\ (Sanskrit: �Nondualism�) Most influential school of  Vedanta. It originated with Gaudapada�s 7th-century commentary on the  Mandukya Upanishad. Gaudapada builds on the Mahayana Buddhist phi�  losophy of emptiness, asserting that there is no duality; the mind, awake  or dreaming, moves through maya (illusion). The mind�s ignorance con�  ceals the truth that there is no becoming and no individual soul or self  (jiva), only a temporary delineation from the atman (all-soul). In the 8th  century Sankara developed Advaita further, arguing that the world is  unreal and that the Upanishads teach the nature of Brahman, the only real�  ity. The extensive Advaita literature influences modem Hindu thought.</p><p>Advent In the Christian calendar, the first season of the church year, a  period of preparation for the birth of Jesus. Advent begins on the Sunday  nearest to November 30 and continues until Christmas. Viewed as a peni�  tential season, it is also considered a time of preparation for the Second  Coming of Christ. The origin of Advent is unknown, but it was observed  as early as the 6th century. In many countries it is celebrated with popu�  lar customs such as the lighting of Advent candles.</p><p>Adventist Member of any of a group of Protestant churches that arose  in the U.S. in the 19th century and believe that the Second Coming of  Christ is close at hand. Adventism was founded during a period marked  by millennialism by William Miller (1782-1849), a former U.S. army  officer, who asserted that Christ would return to separate saints from sin�  ners and inaugurate his 1,000-year kingdom on earth sometime in the year  before March 21, 1844. After that date passed, Miller and his followers  set a new date, Oct. 22, 1844. The �Great Disappointment� was followed  by a Mutual Conference of Adventists in 1845. Those who persisted con�  cluded that Miller had misinterpreted the signs and that, though Christ  had begun the �cleansing of the heavenly sanctuary,� he would not appear  until he had completed that task. These Millerites founded the Seventh-  Day Adventists in 1863; other Adventist groups include the Evangelical  Adventists and the Advent Christian Church. Seventh-Day Adventists  observe Saturday as the Sabbath and avoid eating meat and using narcot�  ics or stimulants.</p><p>adversary procedure In Anglo-American law, the principal method  of offering evidence in court. It requires the opposing sides to present per�  tinent information and to introduce and cross-examine witnesses before  a jury and/or a judge. Each side must conduct its own investigation. In  criminal proceedings, the prosecution represents the government and has  at its disposal the police department with its investigators and laborato�  ries; the defense must arrange and pay for its own investigation. (Legal  aid is available for the poor.) In civil (noncriminal) proceedings the adver�  sary system works similarly, except that both sides engage private attor�  neys to prepare their cases. Skillful questioning often produces testimony  that can be interpreted in various ways; in cross-examination, lawyers  seek to alter the jury�s initial perception of the testimony.</p><p>adverse possession In Anglo-American property law, holding of real  property (see real and personal property) with the knowledge and against  the will of one who has a superior ownership interest in it. Statutes of  limitation in most U.S. states allow an adverse possessor to acquire legal  title if the owner does not seek timely possession.</p><p>advertising Techniques and practices used to bring products, services,  opinions, or causes to public notice for the purpose of persuading the pub�  lic to respond in a certain way. Weekly newspapers in London first carried  advertisements in the 17th century; by the 18th century such advertising  was flourishing. The first advertising agencies were established in the 19th  century to broker for space in newspapers, and by the early 20th century  agencies were producing the advertising message itself, including copy  and artwork. Most advertising promotes goods for sale, but similar meth�  ods are used in public service messages to promote causes, charities, or  political candidates. In many countries, advertising is the most important  source of income for the media through which it is conducted. In addition  to newspapers, magazines, and broadcast media, advertising media</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>20 I Adwa &#x25BA; aepyornis</p><p>include direct mail (see direct-mail marketing), billboards and posters, tran�  sit advertising, the Internet, and promotional items such as matchbooks or  calendars.

The  colony of Eritrea was carved out in the ensuing peace negotiations.</p><p>adze or adz Hand tool for shaping wood. A handheld stone chipped to  form a blade, it is one of the earliest tools, and was used widely in the  Paleolithic and Neolithic periods. By Egyptian times, it had acquired a  wooden haft (handle) with a copper or bronze blade set flat at the top of  the haft to form a T. In this form but with a steel blade, it continued to  be the prime hand tool for shaping and trimming wood; the carpenter  stands on or astride a log or other piece of timber, swinging the adze like  a pick, down and between the legs.</p><p>A \'a-'e\ orig.

A leading figure in the Irish Literary Renaissance, he  published many books of verse, including Homeward (1894). Though ini�  tially considered by many to be the equal of William Butler Yeats, he did  not develop as a poet, and many critics found him facile, vague, and  monotonous. His pseudonym arose from a proofreader�s query about an  earlier pseudonym, jEon.</p><p>Aegean \e-'je-9n\ civilizations The Bronze Age civilizations that  arose and flourished c. 3000-1000 bc in the region bordering the Aegean  Sea.

Located 16 mi  (26 km) southwest of Piraeus, it has an area of 32 sq mi (83 sq km). Its  chief town and port, Aegina, lies over the ancient town of the same name.  Inhabited since c. 3000 bc, it became a maritime power after the 7th cen�  tury bc; its period of glory, reflected in Pindar�s poetry, was in the 5th cen�  tury bc. Its economic rivalry with Athens led to frequent warfare, and in  431 bc the Athenians deported all its population. It came under Roman  rule in 133 bc.

It is usually a long, narrow, shallow  box with soundholes and 10 or 12 strings strung lengthwise between two  bridges. The strings are of the same length but different thicknesses and  are all tuned to the same pitch; the wind makes them vibrate in succes�  sively higher harmonics. The harp may be hung, or set horizontally under  a window sash. The first known Aeolian harp was constructed c. 1650 by  Athanasius Kircher (1601-1680).</p><p>Aeolus Ye-a-lssV Greek god of the winds. In the Odyssey Homer repre�  sents Aeolus as the mortal ruler of the floating island of Aeolia. He gives  Odysseus a favourable wind for his voyage and a bag in which the  unfavourable winds are confined, but Odysseus�s careless companions  open the bag, releasing the winds and driving their ship back to shore.  Later writers depicted Aeolus as a minor god rather than a human being.

During the republic (509-27 bc), two quaestors man�  aged the treasury and the Senate controlled it. All revenues were paid into  the aerarium, and approved payments were made from it. Under the prin-  cipate (27 bc-ad 305) the aerarium lost funds and importance as emper�  ors and magistrates bypassed Senate control and drew directly from the  fisci (provincial treasuries). From ad 6 Augustus used taxes to fund the  aerarium militare, a public treasury, to reward veterans, and the aerar�  ium Saturni became the treasury of the city of Rome.</p><p>aerial See antenna</p><p>aerial perspective Method of producing a sense of depth in a paint�  ing by imitating the effect of atmosphere that makes objects look paler,  bluer, and hazier or less distinct in the middle and far distance. The term  was coined by Leonardo da Vinci, but the technique can be seen in ancient  Greco-Roman wall paintings (e.g., at Pompeii). It was discovered that dust  and moisture in the atmosphere caused the scattering of light passing  through it; short-wavelength light (blue) is scattered most and long-  wavelength light (red) least. Italian painters in Leonardo�s time used the  device; it was exploited by 15th-century northern European artists and  later by J.M.W. Turner.</p><p>aerobatics Sport of performing maneuvers such as rolls, loops, stalls,  spins, and dives with an airplane.

Aerobic exercises (e.g., running, jogging,  swimming, dancing) stimulate heart and lung activity. To produce a ben�  efit, aerobic training must raise the heart rate (pulse) to the exerciser�s  target level for at least 20 minutes and include at least three sessions a  week. The concept of aerobics was pioneered by Kenneth H. Cooper and  popularized in his books Aerobics (1968) and The Aerobics Way (1977).</p><p>aerodynamics Branch of physics concerned with the forces acting on  bodies passing through air and other gaseous fluids. It explains the prin�  ciples of flight of aircraft, rockets, and missiles. It is also involved in the  design of automobiles, trains, and ships, and even stationary structures  such as bridges and tall buildings, which must withstand high winds.  Aerodynamics emerged as a discipline around the time of Wilbur and  Orville Wright�s first powered flight in 1903.

Founded in 1928 as Dobroflot, it was reorganized as Aer�  oflot in 1932. During the Soviet era Aeroflot was the world�s largest air�  line, with about 15% of all civil air traffic. After the 1991 breakup of the  Soviet Union, Aeroflot surrendered its monopoly over commercial air  travel in the former Soviet states. It was renamed Aeroflot-Russian Air�  lines in June 2000.</p><p>aerosol System of tiny liquid or solid particles evenly distributed in a  finely divided state through a gas, usually air. Aerosol particles partici�  pate in chemical processes and influence the electrical properties of the  atmosphere. Though true aerosol particles range in diameter from a few  nanometres to about one micrometre, the term is commonly used to refer  to fog or cloud droplets and dust particles, which can have diameters of  more than 100 micrometres. See also colloid; emulsion.</p><p>aerospace engineering Field concerned with the development,  design, construction, testing, and operation of airplanes and spacecraft. The  field has its roots in balloon flight, gliders, and airships, and in the 1960s  it was broadened to include space vehicles. Principal technologies are  those of aerodynamics, propulsion, structure and stability, and control.  Aerospace engineers in academic, industrial, and government research  centres cooperate in designing new products. Flight testing of prototypes  follows, and finally quantity production and operation take place. Impor�  tant developments in aerospace engineering include the metal monocoque  fuselage, the cantilevered monoplane wing, the jet engine, supersonic  flight, and spaceflight.</p><p>aerospace medicine Branch of medicine, pioneered by Paul Bert,  dealing with atmospheric flight (aviation medicine) and space flight (space  medicine). Intensive preflight simulator training and attention to design  of equipment and spacecraft promote the safety and effectiveness of  humans exposed to the stresses of flight and can prevent some problems.  The world�s first unit for space research was established in the U.S. in  1948. Physicians trained in aerospace medicine are known as flight sur�  geons.</p><p>Aeschines Ves-ko-.nezX (b. 390 bc �d. c. 314 bc) Athenian orator. He  and Demosthenes, who later became his bitter opponent, participated in  346 bc in forging a peace between Athens and Macedonia. Demosthenes  later accused Aeschines of treason because he had promoted the Mace�  donian cause during the negotiations. At a trial (343) Aeschines was  acquitted by a narrow majority. In 339 he helped incite the war that led  to the Battle of Chaeronea and to Macedonian control of central Greece.  In 336 he opposed as illegal a motion to honour Demosthenes; the mat�  ter came to trial in 330, and Aeschines suffered an overwhelming defeat.</p><p>Aeschylus Ves-ko-.bsX (b. 525/524�d. 456/455 bc, Gela, Sicily) Greek  tragic dramatist. He fought with the Athenian army at Marathon (490)  and in 484 achieved the first of his many victories at the major dramatic  competition in Athens. He wrote over 80 plays, but only 7 are extant; the  earliest of these, Persians, was performed in 472 bc. Other plays that sur�  vive are the Oresteia trilogy ( Agamemnon, The Libation Bearers, and The  Eumenides ), Seven Against Thebes, The Suppliants, and Prometheus  Bound. Considered the father of Greek tragic drama, he added a second  actor to the performance, an innovation that enabled the later develop�  ment of dialogue and created true dramatic action. He was the first of the  three great Greek tragedians, preceding Sophocles and Euripides.</p><p>Aesculapius See Asclepius</p><p>Aesir \'a-zir\ In Germanic religion, one of the two main groups of dei�  ties, the other being the Vanir. Odin, his wife Frigg, Tyr (the god of war),  and Thor were the four Aesir common to the Germanic nations. Balder  and Loki were considered Aesir by other peoples. The Aesir were a war�  like race and were originally dominant over the Vanir, but after numer�  ous defeats in battle they were forced to grant the Vanir equal status. The  poet-god Kvasir was born out of the peace ritual in which the two races  mingled their saliva in the same vessel.</p><p>Aesop \'e-,sap\ Supposed author of a collection of Greek fables, almost  certainly a legendary figure. Though  Herodotus, in the 5th century bc, said  that he was an actual personage,</p><p>�Aesop� was probably no more than  a name invented to provide an author  for fables centring on beasts. Aeso�  pian fables emphasize the social  interactions of human beings, and  the morals they draw tend to embody  advice on how to deal with the com�  petitive realities of life. The Western  fable tradition effectively begins  with these tales. Modern editions list  some 200 Aesopian fables.</p><p>Aestheticism \es- , thet-9-,siz-9m\</p><p>Late 19th-century European arts  movement that centred on the doc�  trine that art exists for the sake of its  beauty alone. It began in reaction to  prevailing utilitarian social philoso�  phies and to the perceived ugliness and philistinism of the industrial age.  Its philosophical foundations were laid by Immanuel Kant, who proposed  that aesthetic standards could be separated from morality, utility, or plea�  sure. James McNeill Whistler, Oscar Wilde, and Stephane Mallarme raised  the movement�s ideal of the cultivation of refined sensibility to perhaps  its highest point. Aestheticism had affinities with French Symbolism and  was a precursor of Art Nouveau.</p><p>aesthetics \es-'thet-iks\ Philosophical study of the qualities that make  something an object of aesthetic interest and of the nature of aesthetic  value and judgment. It encompasses the philosophy of art, which is chiefly  concerned with the nature and value of art and the principles by which it  should be interpreted and evaluated.

Seminal  works in the field include the Symposium of Plato ; the Rhetoric of Aris�  totle; Inquiry into the Original of Our Ideas of Beauty and Virtue (1725),  by Francis Hutcheson (1694-1746); �Of the Standard of Taste� (in Four  Dissertations [1757]), by David Hume; On the Sublime and Beautiful  (1757), by Edmund Burke; Critique of Judgment (1790), by Immanuel Kant;  The Sense of Beauty (1896), by George Santayana; The Psychology of  Imagination (1948), by Jean-Paul Sartre; and two works by Ludwig Witt�  genstein, Lectures and Conversations on Aesthetics, Psychology, and Reli�  gious Belief (1966) and Culture and Value (1977).</p><p>Aethelberht I See Ethelbert I</p><p>Aethelred Unraed See Ethelred II</p><p>Aetolia \e-'to-le-3\ District north of the Gulf of Corinth, ancient Greece.  Aetolia figures prominently in early legend. By 367 bc it had been orga�  nized by various tribes into a federal state comprising the Aetolian League.  Coming under Roman rule, it was incorporated into the province of  Achaea (see Achaean League) in 27 bc by Augustus. Governed later by  Albania and Venice, it came under Turkish rule in ad 1450. It was the  scene of fierce fighting in the War of Greek Independence (1821-29). Mod�  em Aetolia is linked with Acarnania as a department of Greece.</p><p>Aetolian \e-'to-le-3n\ League Federal state of ancient Aetolia in cen�  tral Greece, probably based on a looser tribal community. A leading power  by c. 340 bc, the Aetolian League resisted invasions by Macedonia in 322  and 314-311, expanded into Delphi, and allied with Boeotia c. 300. It  fended off the Gauls in 279 and formed an alliance with Macedonia (c.  270-240). The league�s power in central Greece was confirmed with the  defeat of the Boeotians (245). From the late 3rd century Aetolia began to  lose power and territory to Macedonia, culminating in the sacking of the  league�s federal capital, Thermum, by Philip V in 220. The league then  allied with Rome against Macedonia and defeated Philip at Cynosceph-  alae (197). Rome later forced it into a permanent alliance (189) that cost  it territory, power, and independence.</p><p>Afars and Issas, French Territory of the See Djibouti</p><p>Affair of the Diamond Necklace (1785) Scandal at the court of  Louis XVI that discredited the French monarchy on the eve of the French  Revolution. An adventuress, the countess de la Motte, schemed to acquire  a valuable diamond necklace by duping cardinal de Rohan into believing  that Queen Marie-Antoinette wanted to obtain it surreptitiously and that  he could gain her favour by facilitating its purchase. When the plot came  to light, Louis XVI had the cardinal arrested. Though acquitted, the arbi�  trary treatment of the cardinal deepened impressions of the autocratic  nature of the king�s government.</p><p>affective disorder Mental disorder characterized by dramatic changes  or extremes of mood. Affective disorders may include manic or depres�  sive episodes less severe than those of bipolar disorder, such as anxiety  and depression. Symptoms include elevated, expansive, or irritable  moods, with hyperactivity, pressured (rapid and forced) speech, and  inflated self-esteem; or dejected moods, characterized by lack of interest  in life, sleep disturbances, agitation, and feelings of worthlessness or guilt.</p><p>affenpinscher Va-fon-.pin-choA Sturdy breed of toy dog, known since  the 17th century. Standing 10 in. (26 cm) high or less and weighing 7-8 lbs  (3-3.5 kg), it is a TERRiER-like dog with small, erect ears, round black eyes,  and a short, docked tail.

First undertaken at the federal level following passage of the land�  mark Civil Rights Act of 1964, affirmative action was designed to  counteract the lingering effects of generations of past discrimination. The  main criteria for inclusion in affirmative action programs are race, sex,  ethnic origin, religion, disability, and age. The Supreme Court of the United  States placed important limitations on affirmative action programs in its  1978 ruling in Regents of the University of California v. Bakke; several sub�  sequent Supreme Court decisions (e.g., Adarand Constructors v. Pena in  1995 and Texas v. Hopwood in 1996) imposed further restrictions. In 1996  California voters passed Proposition 209, which prohibited government  agencies and institutions from discriminating against or giving preferen�  tial treatment to individuals or groups on the basis of race, sex, colour,  ethnicity, or national origin. Similar measures were subsequently passed  in other states. In 2003, in two landmark rulings involving admission to  the University of Michigan and its law school, the U.S. Supreme Court  reaffirmed the constitutionality of affirmative action but ruled that race  could not be the preeminent factor in such decisions.</p><p>Affleck, Thomas (b. 1745, Aberdeen, Scot.�d. 1795, Philadelphia,  Pa., U.S.) Scottish-bom U.S. cabinetmaker.

It  has floppy ears, a long topknot, and  a long silky coat of various colours.</p><p>Afghan wars Series of wars in  Afghanistan during the 19th, 20th,  and early 21st centuries. In the 19th  century Britain twice invaded  Afghanistan (the first and second  Anglo-Afghan Wars; 1839-40 and 1878-80). The British were unable to  fully subdue the country, and the third Anglo-Afghan War (1919) led to  its full independence. The outbreak of civil war in 1978 led to an inva�  sion by the Soviet Union the following year (the Afghan War). For the  next 10 years the Soviets supported the communist government against a  coalition of Islamic insurgents, the mujahideen, who toppled the regime in  1992. A group of disaffected fighters known as the Taliban had taken con�  trol of most of the country by 1996. The ensuing stalemate was broken  in 2001 when the U.S. overthrew the Taliban for supporting international  terrorism.</p><p>Afghani, Jamal al-DTn al- See Jamal al-Din al-AfghanI</p><p>Afghanistan officially Islamic State of Afghanistan Country,  south-central Asia. Area: 249,347 sq mi (645,807 sq km). Population  (2005 est.: 23,867,000). Capital: Kabul. About two-fifths of the people  belong to the Pashtun ethnic group; other ethnic groups include Tajiks,  Uzbeks, and Hazara. Languages: Pashto, Persian (both official). Religions:  Islam (official; predominantly Sunni); also Zoroastrianism. Currency:  afghani. Afghanistan has three distinctive regions: the northern plains are  the major agricultural area; the southwestern plateau consists primarily of  desert and semiarid landscape; and the central highlands, including the  Hindu Kush, separate these regions. Afghanistan has a developing economy  based largely on agriculture; its significant mineral resources remain  largely untapped because of the Afghan War of the 1980s and subsequent  fighting. Traditional handicrafts remain important; woolen carpets are a  major export. The area was part of the Persian Achaemenian Empire in  the 6th century bc and was conquered by Alexander the Great in the 4th  century bc. Hindu influence entered with the Hephthalites and Sasanians;  Islam became entrenched during the rule of the Saffarids, c. ad 870.</p><p>Afghan hound</p><p>SALLY ANNE THOMPSON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>AFL-CIO &#x25BA; Africa I 23</p><p>UZBEKISTAN</p><p>Dushanbe TAJIKISTAN</p><p>Andkhvoy^</p><p>Dowlatabad</p><p>\Aqchah</p><p>Mazar-e*</p><p>Sharif</p><p>/ (#Almar ^Kuhestanat</p><p>~\ r ^*'ORKESTAN MTS.</p><p>' &amp;k</p><p>g' T^ Owbeh ^.- UMtMlgdl*</p><p>rfeTal-^�^Shahrak f 16,843 ft.</p><p>*^dH^Svc^r�</p><p>r RaiaK^J / iudr^V</p><p>Boluk Porchdmarf^ ^^OriWgark</p><p>*Farih . * E " les,5n .Kajaki /A&lt;k</p><p>' " TwpMm/</p><p>Chakhansur <emphasis>Lashkar </emphasis>Kandahar</p><p>� - *� .. / Gah -</p><p>r</p><p>Khanabad</p><p>Sayghan</p><p>-%MahMud^  ^ Bagram</p><p>Islamabad</p><p>Chahar</p><p>Palalak</p><p>AFGHANISTAN</p><p>� 2002 Encyclopaedia Britani</p><p>TURKMENISTAN</p><p>IRAN</p><p>Afghanistan was divided between the  Mughal Empire of India and the Safavid  empire of Persia until the 18th century,  when other Persians under Nadir Shah took  control.

Marxist reforms sparked rebel�  lion, and Soviet troops invaded. Afghan guerrillas prevailed, and the  Soviets withdrew in 1989. In 1992 rebel factions overthrew the govern�  ment and established an Islamic republic. In 1996 the Taliban militia took  power in Kabul and enforced a harsh Islamic order. The militia�s unwill�  ingness to extradite extremist leader Osama bin Laden and members of his  al-Qaeda militant organization following the September 11 attacks in 2001  led to military conflict with the U.S. and allied nations, the overthrow of  the Taliban, and the establishment of an interim government.</p><p>AFL-CIO in full American Federation of Labor-Congress of  Industrial Organizations U.S. federation of labour unions formed  in 1955 by the merger of the AFL and the CIO. The AFL was founded in  1886 as a loose federation of craft unions under the leadership of Samuel  Gompers. Member unions retained autonomy and received protection of  their workers and jurisdiction over a certain industrial territory. The CIO  was founded in 1935 as the Committee for Industrial Organization by a  splinter group of AFL unions whose leaders believed in organizing skilled  and unskilled workers across entire industries; at its first convention in  1938, it adopted its current name and elected John L. Lewis president. For  two decades the AFL and CIO were bitter rivals for the leadership of the  U.S. labour movement, but they formed an alliance in the increasingly  conservative, antilabour climate of the postwar era, and in 1955 they  merged under the leadership of George Meany. AFL-CIO membership  reached 17 million in the late 1970s but declined from the 1980s as the  U.S. manufacturing sector shrank. AFL-CIO activities include recruiting  and organizing members, conducting educational campaigns, and sup�  porting political candidates and legislation deemed beneficial to labour.

While studying at the  University of Paris (1929-34), he came to believe that the Arab nation�  alist struggle had to oppose both the native aristocracy and foreign rul�  ers. Hoping to unite all the Arab states into a single socialist nation  through nonviolence, he helped establish the Ba'th Party in 1946 and  served as its teacher, theorist, and organizer. He persuaded the Syrian  government to form the United Arab Republic with Egypt in 1958, but  Syria withdrew from it in 1961. His career in Syrian politics ended in  1966 when he moved to Lebanon.

Port.�d. Dec. 6, 1185, Coimbra) First king of Portugal (1139-85).  He defeated his mother to take the throne (1128), ruling first as a vassal  of his cousin Alfonso VII of Leon but later securing Portuguese indepen�  dence and gaining the title of king (1139). He defeated nearby Muslims  and imposed tribute on them, then took Lisbon (1147) with the help of  Crusaders. Afonso eventually extended Portugal beyond the Tagus River.  He shared power with his son Sancho I and left him a stable, independent  monarchy.</p><p>Afonso III (b. May 5, 1210, Coimbra, Port.�d. Feb. 16, 1279, Lisbon)  King of Portugal (1248-79). He emigrated to France and became, by  marriage, count of Boulogne. He gained the Portuguese crown when his  older brother Sancho II was deposed by order of the pope. As king, Afonso  regained control of the district of Faro (1249) and completed the recon�  quest of the Algarve from the Muslims. His reign saw the first admission  of commoners to the Portuguese Cortes (parliament). Afonso�s assertion  of the royal right to repossess church lands led to his excommunication  by the pope.</p><p>Afonso the Great See Afonso de Albuquerque</p><p>Africa Second largest continent on Earth. It is bounded by the Mediter�  ranean Sea, the Atlantic Ocean, the Red Sea, and the Indian Ocean and is  divided almost equally by the Equator. Area: 11,717,370 sq mi  (30,348,110 sq km). Population (2001 est.): 816,524,000. Africa is com�  posed largely of a rigid platform of ancient rocks that underlies vast pla�  teau regions in the interior. Its average elevation is about 2,200 ft (670  m), but elevations range from 19,340 ft (5,895 m) at Mount Kilimanjaro  to 515 ft (157 m) below sea level at Lake Assal. The Sahara, the world�s  largest contiguous desert, occupies more than one-fourth of the total land  area. The continent�s hydrology is dominated by the Nile River in the north,  the Niger River in the west, and the Congo River in central Africa. Less  than one-tenth of the land area is arable, while nearly one-fourth is for�  ested or wooded. The peoples of Africa probably speak more languages  than those of any other continent. Arabic is predominant from Egypt to  Mauritania and in The Sudan. Northern Africans speak a family of lan�  guages known as Afro-Asiatic. The vast majority of sub-Saharan peoples  speak Bantu languages of the Niger-Congo family, while smaller num�  bers in central Africa speak Nilo-Saharan languages and in southern  Africa Khoisan languages. Peoples of European descent are found mostly  in the south; Dutch (Boer) migrations began in the 17th century, and the  English first settled in what is now Kenya and Zimbabwe in the 19th cen�  tury. Africa as a whole is a developing region. Agriculture is the key sec�  tor of the economy in most countries. Diamond and gold mining are  especially important in the south, while petroleum and natural gas are  produced particularly in the west. Most African governments are con�  trolled by the military or a single party. Many legal systems combine laws  introduced by European powers during the colonial era with traditional  law, though North African countries derive many laws from Islam. Afri�  can leaders have sought to develop a pan-African approach to the conti�  nent�s political and military affairs through the Organization of African  Unity and its successor, the African Union. Africa is widely recognized as  the birthplace of humankind. Archaeological evidence indicates that the  continent has been inhabited by humans and their hominid forebears for  some 4,000,000 years or more. Anatomically modern humans are believed  to have appeared about 100,000 years ago in the eastern region of sub-  Saharan Africa. Somewhat later these early humans spread into northern  Africa and the Middle East and, ultimately, to the rest of the world. Afri�  ca�s first great historical kingdom, Egypt, arose along the Nile c. 3000 bc  and flourished for nearly 3,000 years. The Phoenicians established a colony  at Carthage and controlled the western Mediterranean for nearly 600  years. While northern Africa was dominated by the Romans for several  centuries, the first known empire in western Africa was Ghana (5th�11th  century ad). Muslim empires included those of Mali (c. 1250-1400) and  Songhai (c. 1400-1591). In eastern and central Africa the emphasis was  on trade with Arabia, and several powerful city-states, including Moga�  dishu and Mombasa, were established. The Portuguese explored the west�  ern coast in the 15th century. Before the late 19th century, Europe showed  little interest in colonizing Africa, but by 1884 European countries had</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>24 I Africa &#x25BA; Afrikaner</p><p>begun a scramble to partition the continent, and by 1920 much of it was  under colonial rule. Anticolonial sentiment developed gradually, becom�  ing widespread after 1950, and one by one the colonies became indepen�  dent, the last in 1990. Political instability, refugee problems, famine, and  AIDS are the chief problems facing the continent at the start of the 21st  century. See map on following page.</p><p>Africa Proconsular Roman province. It was founded after Rome defeated  Carthage in 146 bc and was subsequently extended to include Numidia and  the northern part of modem Libya. Between 30 bc and ad 180, other parts  of northern Africa, including Cyrenaica and Mauretania, became part of  the Roman Republic and Empire. In the 5th century the region was taken by  the Vandals, though areas were later reconquered by the Byzantine (Eastern  Roman) Empire; the Muslims conquered the area in the late 7th century.</p><p>Africa, Horn of See Horn of Africa</p><p>African ant bear See aardvark</p><p>African arts Visual, performing, and literary arts of sub-Saharan  Africa. What gives art in Africa its special character is the generally small  scale of most of its traditional societies, in which one finds a bewildering  variety of styles. The earliest evidence of visual art is provided by fig�  ures scratched and painted on rocks c. 3000 bc. Pastoral cultures in the  east emphasize personal adornment; sculpture predominates in the agri�  cultural societies in the west and south. Clay figurines found in Nigeria  date to 500 bc. Metalworking was practiced from the 9th century ad.  Sculptures in stone, ivory, and wood date from the 16th-17th centuries;  some of the finest wood sculptures date from the 20th century. Architec�  ture dominates the arts of the north and of the eastern coast, where Islam  and Christianity exerted their influence; important work includes mag�  nificent mosques built of mud and rock-hewn churches. Perhaps the most  distinctive features of African music are the complexity of rhythmic pat�  terning achieved by a great variety of drums and the relationship between  melodic form and language tone structure. Without this the text of a song  is rendered meaningless; but, even in purely instrumental music, melodic  pattern is likely to follow speech tone. Dances are realized in radically  different styles throughout Africa. Movement patterns often depend upon  the way in which environmental, historical, and social circumstances have  been articulated in working, social, and recreational movements. Often  there is no distinction between ritual celebration and social recreation. The  masquerade is a complex art form employing many media; masquerades  may entertain, be used to fight disease, be consulted as oracles, initiate  boys to manhood, impersonate ancestors, judge disputes, or execute crimi�  nals. The mask is essentially a dramatic device enabling performers to  stand apart from their everyday role in the community. The content and  style of urban African theatre are influenced by both African dramatic tra�  ditions and Western theatre. The literary arts of Africa�especially its oral  traditions�are immensely rich and varied. They include myths, praise  songs, epic poetry, folktales, riddles, spells, and proverbs. Written litera�  tures have existed for several centuries in Hausa, Swahili, and Amharic.  In the 20th century, written literatures in other African languages also  developed, alongside those in English, French, and Portuguese. See also  Buu style; deble; segoni-kun; telum figure; trickster tale; and African authors  by name, such as Chinua Achebe; Aime Cesaire; Birago Diop; Athol Fugard;  Nadine Gordimer; Wole Soyinka; Amos Tutuola.</p><p>African languages Languages indigenous to Africa that belong to the  Niger-Congo, Nilo-Saharan, Khoisan, and Afro-Asiatic language phyla.  Africa is the most polyglot continent; estimates of the number of African  languages range from 1,000 to more than 1,500. Many have numerous  dialects. Distinctions in tone play a significant role in nearly all sub-  Saharan languages. Contact between people who do not speak the same  language has necessitated the development of lingua francas such as Swa�  hili in East Africa, Lingala in the Congo River basin (see Bantu languages),  Sango in the Central African Republic (see Adamawa-Ubangi languages),  and Arabic across much of the Sahel.</p><p>African lily or lily of the Nile Perennial evergreen herbaceous plant  (Agapcinthus africanus) of the lily family, native to Africa.

If grown in a climate with  frost, they must be kept in containers and moved indoors to survive the  cold weather.</p><p>African lion dog See Rhodesian ridgeback</p><p>African Methodist Episcopal Church (AME Church) African  American Methodist denomination formally organized in 1816. It origi�  nated with a group of black Philadelphians who withdrew in 1787 from  St. George�s Methodist Episcopal Church (see Methodism) because of  racial discrimination and built Bethel African Methodist Church. In 1799  Richard Allen became minister of Bethel, and in 1816 he was consecrated  bishop of the newly organized African Methodist Episcopal Church. Lim�  ited at first to the Northern states, the church spread rapidly in the South  after the Civil War. It founded many colleges and seminaries, notably  Wilberforce University (1856) in Ohio. In the late 20th century the church  claimed 3,500,000 members and 8,000 congregations. Its headquarters are  in Washington, D.C.</p><p>African National Congress (ANC) South African political party  and black nationalist organization. Founded in 1912 (as the South African  Native National Congress), the ANC was long dedicated to the elimination  of apartheid. In response to government massacres of demonstrators at  Sharpeville (1960) and Soweto (1976), it carried out acts of sabotage and  guerrilla warfare. The campaign was largely ineffective because of strin�  gent South African internal security measures, including an official ban on  the ANC between 1960 and 1990. In 1991, with the ban lifted, Nelson  Mandela succeeded Oliver Tambo as ANC president. In 1994 the party  swept the country�s first elections based on universal suffrage; the ANC  led a coalition government that initially included members of its longtime  rival, the National Party, and Mandela became South Africa�s president.  In 1999 Thabo Mbeki replaced him as president of the ANC and of South  Africa.

The  introduced religions of Islam (in northern Africa) and Christianity (in  southern Africa) are now the continent�s major religions, but traditional  religions still play an important role, especially in the interior of sub-  Saharan Africa. The numerous traditional African religions have in com�  mon the notion of a creator god, who made the world and then withdrew,  remaining remote from the concerns of human life. Prayers and sacrifi�  cial offerings are usually directed toward secondary divinities, who are  intermediaries between the human and sacred realms. Ancestors also serve  as intermediaries (see ancestor worship). Ritual functionaries include  priests, elders, rainmakers, diviners, and prophets. Rituals are aimed at  maintaining a harmonious relationship with cosmic powers, and many  have associated myths that explain their significance. Animism is a com�  mon feature of African religions, and misfortune is often attributed to  WITCHCRAFT AND SORCERY.</p><p>African Union (AU) African intergovernmental organization. It is the  successor to the Organization of African Unity (OAU). The AU was estab�  lished in 2002 to promote unity and solidarity among African states, spur  economic development, and promote international cooperation. The OAU  was established in 1963 with similar goals, and during its tenure the group  mediated several border disputes on the African continent. More eco�  nomic in nature and with a stronger mandate to intervene in conflicts, the  AU replaced the OAU in 2002. In 2004 the AU�s Pan-African Parliament  was inaugurated, and the organization agreed to create a peacekeeping  force. The AU�s headquarters are in Addis Ababa, Eth.</p><p>African violet Any plant of the genus Saintpaulia, of the gesneriad  family, especially S. ionantha. African violets are native to high eleva�  tions in tropical eastern Africa. They are small, hairy, usually stemless  herbaceous plants with crowded, long-stalked leaves. The violet, white,  or pink flowers bloom most of the year. They are popular houseplants,  and hundreds of varieties have been developed, including half-sized min�  iatures.</p><p>Afrikaans \,af-ri-'kanz\ language Germanic language of South  Africa. It was developed from 17th-century Dutch by descendants of Euro�  pean settlers, indigenous KHOlSAN-speaking peoples, and African and Asian  slaves in the Dutch colony at the Cape of Good Hope. It differs from Dutch  in its sound system, in some grammatical simplification, and in vocabulary.  Afrikaans is spoken as a first language by close to six million South Afri�  cans and as a second or third language by several million more; there are  also about 150,000 Afrikaans speakers in Namibia. Standard Afrikaans was  formally separated from Dutch and made an official language in South  Africa in 1925; it is one of 11 official South African languages.</p><p>Afrikaner V.af-ri-'kan-orV formerly Boer Historically, any South Afri�  can of Dutch or Huguenot descent whose native language is Afrikaans.

The Afrikaners were originally  called Boers (�farmers�), since many Dutch and Huguenot settlers of the  old Cape Colony (founded 1652) became frontier farmers in the Trans�  vaal and the Orange Free State. They established self-sufficient patriarchal  communities, developed their own language and subculture, and were  committed to a policy of racial segregation, later referred to as apartheid.  They fought a bitter war with the British (the South African War, 1899�  1902) over the right to govern the frontier territories. Though defeated,  they retained their old language and culture and eventually attained politi�  cally the power they had failed to win militarily. They dominated South  African politics for most of the 20th century but were obliged to give up  national power after the first elections based on universal suffrage in 1994.  See also Cape Town; Great Trek; National Party.</p><p>Afro-Asiatic languages formerly Hamito-Semitic languages</p><p>Family of about 250 languages spoken in North Africa, parts of sub-  Saharan African, and the Middle East. It includes such languages as Ara�  bic, Hebrew, Amharic, and Hausa. The total number of speakers is estimated  to be more than 250 million. The major branches of Afro-Asiatic are  Semitic, Berber, Egyptian, Cushitic, Omotic, and Chadic. Berber languages  are spoken by perhaps 15 million people in enclaves scattered across  North Africa from Morocco to northwestern Egypt and in parts of the  western Sahara. Cushitic consists of some 30 languages spoken by more  than 30 million people in northeastern Sudan, Eritrea, Ethiopia, Somalia,  Djibouti, Kenya, and a few areas of northeastern Tanzania. Omotic, for�  merly classified as part of Cushitic, is a cluster of perhaps more than 30  languages spoken by 2-3 million people, most of whom live near the Omo  River in southwestern Ethiopia. Chadic comprises about 140 languages,  spoken in northern Nigeria, southern Niger, southern Chad, and northern  Cameroon; except for Hausa, it is likely that no individual Chadic lan�  guage has more than half a million speakers.</p><p>Afro-Caribbean, Afro-Brazilian, and Afro-American reli�  gions Religions among persons of African ancestry in the Caribbean,  Brazil, and U.S. These include Haitian vodun, the Jamaican Rastafarian  movement, Santeria, and Candomble and other Macumba sects in Brazil.  Similarly syncretistic religions appeared in the U.S. during the era of sla�  very. The Nation of Islam combines black nationalism with an unortho�  dox version of Islam. Black Protestant churches (especially Baptist and  Pentecostal) have imported some forms of lively worship from Africa.</p><p>Afrocentrism Cultural, political, and ideological movement. Most  Afrocentrists are African Americans who regard all blacks as syncretic  Africans and who believe that their worldview should positively reflect  traditional African values. Afrocentrists argue that for centuries blacks and  other nonwhites have been dominated, through slavery and colonization,  by Europeans and that European culture is either irrelevant or hostile to  efforts by non-Europeans to achieve self-determination. Rooted in his�  torical black nationalist movements such as Ethiopianism, Pan-Africanism,  and Negritude, Afrocentrism asserts the cultural primacy of ancient Egypt  and is seen as a spur to political activism. In addition to emphasizing  cooperation and spirituality, it champions contemporary African Ameri�  can expressive culture (language, cuisine, music, dance, and clothing).  Coined by Molefi Asante in the 1980s, the term Afrocentrism was popu�  larized by such books as Black Athena: The Afroasiatic Roots of Classi�  cal Civilization, 2 vol. (1987-91), by Martin Bernal. The book remains  controversial among mainstream scholars who charge it with historical  inaccuracy, scholarly ineptitude, and racism�prompting countercharges  of racism from some of its defenders.</p><p>afterburner Second combustion chamber in a turbojet or turbofan  engine, immediately in front of the engine�s exhaust nozzle. The injec�  tion and combustion of extra fuel in this chamber provide additional thrust  for takeoff or supersonic flight; in most cases, the afterburner can nearly  double the thrust of a turbojet engine. The jet nozzle must be larger when  using the afterburner, so an automatic, adjustable nozzle is an essential  component of the afterburner system. Because the afterburner sharply  increases fuel consumption and is generally less effective at subsonic  speeds, its use is usually restricted to supersonic military aircraft.</p><p>afterpiece Supplementary entertainment offered after a full-length play  in 18th-century England. A short comedy, farce, or pantomime was pre�  sented to lighten the five-act Neoclassical tragedy that was commonly  performed. A reduced admission price for latecomers, usually after the  third act, enabled less-sophisticated playgoers and working people to see  the end of the drama and the one-act afterpiece.</p><p>aftosa See foot-and-mouth disease</p><p>Aga Khan \,a-g3-'kan\ Persian Agha Khan or Aqa Khan Title of  the imams of the Nizarl Isma'ilT sect of ShTite Islam. The title was first  granted in 1818 to Hasan 'All Shah (1800-81) by the shah of Iran. As Aga  Khan I, he later revolted against Iran (1838) and, defeated, fled to India.  His eldest son, 'All Shah (d. 1885), was briefly Aga Khan II. 'All Shah�s  son Sultan Sir Mohammed Shah (1877-1957) became Aga Khan III. He  acquired a leading position among India�s Muslims, served as president  of the All-India Muslim League, and played an important part in the  Round Table conferences on Indian constitutional reform (1930-32); in  1937 he was appointed president of the League of Nations. He chose as  his successor his grandson Karim al-Husayn Shah (b. 1937), who, as Aga  Khan IV, became a strong leader; he founded the Aga Khan Foundation,  an international philanthropic organization, and other agencies offering  educational and other services.</p><p>Agadir \,a-ga-'dir\ Seaport city (pop., 1994: 155,240), southwestern  Morocco on the Atlantic coast. It was occupied in the 16th century by the  Portuguese but later became an independent Moroccan port. After the  1911 Moroccan Crisis, it was occupied by French troops in 1913. Mod�  ern growth began with the port�s construction in 1914 and the develop�  ment of the fishing industry. In 1960 the city was virtually destroyed by  a pair of earthquakes, a tidal wave, and a fire; a new city centre was rebuilt  south of its original location. It is also a marketplace for the surrounding  agricultural area.</p><p>Agamemnon N.a-gs-'mem-.nanX In Greek legend, the son of Atreus,  brother of Menelaus, and king of Mycenae and commander of the Greek  forces that attacked Troy. By his wife, Clytemnestra, Agamemnon had a  son, Orestes, and three daughters. When Paris carried off Menelaus�s wife,  Helen, Agamemnon called on the Greeks to unite in a war of revenge  against the Trojans. Artemis sent a calm or contrary winds to prevent the  Greek fleet from sailing, and Agamemnon sacrificed his daughter Iphige-  neia to appease the goddess. After the Trojan War he returned home, where  he was killed by his wife and her lover, Aegisthus. His murder was  avenged by Orestes. These events formed the basis of Aeschylus' great  dramatic trilogy the Oresteia.</p><p>Agana See Hagatna</p><p>agape \a-'ga-pa\ In the New Testament, the fatherly love of God for  humans and their reciprocal love for God. The term extends to the love  of one�s fellow humans. The Church Fathers used the Greek term to des�  ignate both a rite using bread and wine and a meal of fellowship that  included the poor. The historical relationship between this meal, the  Lord�s Supper, and the Eucharist, the meal of fellowship and the sacra�  ment, is uncertain.</p><p>agaric \'a-gar-ik\ Any fungus of the family Agaricaceae, including the  familiar commercially grown mushroom. Agarics have SPORE-bearing cells  (basidia) located on thin sheets called gills. Best known of the agarics is  the genus Agaricus (Psalliota ), which includes some 60 species, the most  prominent being the edible meadow, or field, mushroom, A. campestris,  and the common cultivated mushroom, A. bisporus.</p><p>Agartala \3-'g3r-t9-b\ City (pop., 2001 prelim.: 189,387), capital of  Tripura state, India.

Elizabeth Cabot Cary (b. Dec.  5, 1822, Boston, Mass., U.S.�d. June 27, 1907, Arlington Heights,  Mass.) U.S. naturalist and educator. She was educated at home, and in  1850 she married Louis Agassiz. She helped organize and manage several  of his field expeditions, and together they founded a marine laboratory in  Buzzards Bay, Mass. After his death she pursued her idea of a college for  women to be taught by the Harvard University faculty. She was instrumen�  tal in launching the Society for the Collegiate Instruction of Women  (1882); she served as its president until 1894, when it was renamed Rad-  cliffe College, and she continued as president until 1899.</p><p>Agassiz Va-go-seV (Jean) Louis (Rodolphe) (b. May 28, 1807,  Motier, Switz.�d. Dec. 14, 1873, Cambridge, Mass., U.S.) Swiss-born  U.S. naturalist, geologist, and teacher. After studies in Switzerland and  Germany, he moved to the U.S. in 1846. He did landmark work on gla�  cier activity and extinct fishes. He became famous for his innovative  teaching methods, which encouraged learning through direct observation  of nature, and his term as a zoology professor at Harvard University revo�  lutionized the study of natural history in the U.S.; every notable Ameri�  can teacher of natural history in the late 19th century was a pupil either  of Agassiz or of one of his students. In addition, he was an outstanding  science administrator, promoter, and fund-raiser. He was a lifelong oppo�  nent of Charles Darwin�s theory of evolution. His second wife, Elizabeth  Agassiz, cofounder and first president of Radcliffe College, and his son,  Alexander Agassiz, were also noted naturalists.</p><p>agate \'a-got\ Common, semiprecious silica mineral, a variety of chal�  cedony that occurs in bands of vary�  ing colour and transparency.</p><p>Varieties are characterized by pecu�  liarities in the shape and colour of  the bands, which are seen in sections  cut at right angles to the layers.</p><p>Agate is found throughout the world,  commonly in cavities in eruptive  rocks and in geodes. Brazil and Uru�  guay are major producers of agates;  they are also found in Oregon, Wash�  ington, Idaho, Montana, and other  western U.S. states. Agate is essen�  tially quartz. Much commercial  agate is artificially dyed to make the naturally dull-gray stones more  colourful.</p><p>Agate Fossil Beds National Monument Natural �depository� of  an extinct animal community on the Niobrara River, northwestern  Nebraska, U.S. The beds, laid down as sedimentary deposits 20 million  years ago, bear the remains of prehistoric mammals. Discovered c. 1878,  the site was named for its proximity to rock formations containing agates.  A national monument since 1965, it covers 2,269 acres (918 hectares).</p><p>Agatha, Saint (fl. 3rd century ad?, Sicily; feast day February 5) Leg�  endary Christian martyr. Born in Palermo or Catania, she resisted the  advances of a Roman prefect sent to govern Sicily. After brutal torture  she was sent to the stake, but as the fire was lit a great earthquake  occurred, and the crowd demanded her release. She was led away to  prison, where she died. Though she appears in lists of martyrs as early as  the 6th century, the legend may be unfounded.</p><p>Agathocles \3-'ga-th3-klez\ (b. 361 bc, Thermae Himeraeae, Sicily�d.  289) Tyrant of Syracuse (317-304?) and self-styled king of Sicily (304?-  289). He moved to Syracuse as a youth and served in its army. After two  failed attempts, he overthrew the Syracusan oligarchy (317) and took  power. He waged wars with other Sicilian Greek cities (316-313?) and  with Carthage (311), almost capturing Carthage itself before he was  defeated (307). He concluded a favourable treaty (306) that curtailed  Carthaginian expansion in Sicily. Harsh domestic measures kept him in  power, and he declared himself king of Sicily; his reign was peaceful  thereafter. He restored Syracusan liberty in his will, but after his death the  Carthaginians were once again a power in Sicily.</p><p>agave \o-'ga-ve\ family Family Agavaceae of the lily order (Liliales),  comprising more than 700 species of short-stemmed, often woody plants  found in tropical, subtropical, and temperate areas. They have narrow,</p><p>lance-shaped, sometimes fleshy or toothed leaves, which are clustered at  the base of the plant. Most have large flower clusters. The fruit is a cap�  sule or berry. Plants of the genus Agave are important primarily for the  fibres obtained from their leaves. Sisal hemp, from A. sisalana, is the most  valuable hard fibre. Some species of Agave contain a sap that is fermented  to produce the intoxicating drinks known as tequila, pulque, and mescal.  Many species of yucca are popular as ornamentals; other ornamentals in  the agave family include plants of the genera Dasylirion, Nolina,  Cordyline, Dracaena , and Sansevieria.</p><p>age set Formally organized social group consisting of every male (or  female) of comparable age. In societies where the practice traditionally  occurs (e.g., the Nuer of the southern Sudan or the Masai of Kenya and  Tanzania), a person belongs, either from birth or from a determined age,  to a named age set that passes through a series of life stages, or age grades,  each of which has a distinctive status or social and political role.

Agee attended Harvard  University. In the 1930s and �40s, film reviews for Time and The Nation  made him a pioneer in serious film criticism. His lyrical Let Us Now  Praise Famous Men (1941), with photographs by Walker Evans, docu�  ments the daily lives of poverty-stricken Alabama sharecroppers. After  1948 Agee worked mainly as a screenwriter, notably on The African  Queen (1951) and The Night of the Hunter (1955). He is best known for  his autobiographical novel A Death in the Family (1957, Pulitzer Prize).</p><p>Agenais \azh-'ne, a-zho-'na\ or Agenois \a-zhe-'nwa\ Historical  region, southwestern France. In ancient Gaul, Agenais was the country of  the Nitiobriges, then a Gallo-Roman civitas, whose limits became those  of the diocese of Agen. It was acquired by the dukes of Aquitaine in 1036.  When Eleanor of Aquitaine married the future Henry II of England in 1152,  Agenais became the possession of the English kings. It alternated between  French and British rule until it was reunited to the French crown in 1615.</p><p>Agence France-Presse \a-zha n s-fra n s-'pres\ (AFP) French coopera�  tive news agency. Based in Paris, it has roots in the Bureau Havas, cre�  ated in 1832, which in 1835 became the Agence Havas, the world�s first  true news agency. The Agence Havas was active until the German occu�  pation of France in 1940, when many of its personnel went underground.  After the liberation of Paris in 1944, underground journalists emerged to  form AFP. The French government assigned the assets of Agence Havas  to AFP, which quickly became one of the world�s leading wire news ser�  vices. AFP operates bureaus in Africa, Asia-Pacific countries, Latin  America, the Middle East, North America, and Europe.</p><p>agency In law, a relationship in which one party (the agent) acts on  behalf of and under the control of another (the principal) in dealing with  third parties. It has its roots in ancient servant-master relations. Agency  becomes a legal issue when the agent injures or wrongs a third party. In  Anglo-American law, principals are bound by and liable for the acts of  such agents as stockbrokers, business agents, contractors, real-estate  agents, lawyers, union representatives, managing partners, and private  detectives. See also regulatory agency.</p><p>agenesis \a-'je-no-s9s\ Failure of all or part of an organ to develop dur�  ing embryonic growth. Many forms of agenesis are lethal, such as absence  of the entire brain (anencephaly), but agenesis of one organ of a pair may  cause little problem. Agenesis of a kidney, bladder, testicle, ovary, thy�  roid, and lung are known. Agenesis of the arms or legs is called mer-  omelia (absence of one or both hands or feet), phocomelia (normal hands  and feet but no arms or legs), and amelia (complete absence of a limb or  limbs). Agenesis may be caused by absence of embryonic tissue or by  chemical exposure in the uterus, and it is often associated with other con�  genital disorders.</p><p>Agent Orange Mixture of herbicides. It contains approximately equal  amounts of esters of 2,4-D (2,4-dichlorophenoxyacetic acid) and 2,4,5-T  (2,4,5-trichlorophenoxyacetic acid) and trace amounts of dioxin. About 13  million gallons were sprayed by U.S. military forces onto Vietnam�s for�  ests and crops during the Vietnam War, with the dual purpose of destroy�  ing cover for enemy movements and destroying food sources. Exposure  to Agent Orange has been blamed for an abnormally high incidence of  miscarriages, skin diseases, cancers, birth defects, and malformations  among Vietnamese and of cancers and other disorders in U.S., Australian,  and New Zealand servicemen and their families.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>28 I ageratum &#x25BA; agouti</p><p>ageratum \ l a-j3- , ra-t3m\ Any plant of the genus Ageratum, of the com�  posite family, native to tropical South America. Ageratum have toothed,  oval leaves that are opposite each other on the stem; compact clusters of  blue, pink, lilac, or white flowers; and small, dry fruits. Dwarf varieties  are used as edging plants. Some ageratum are variously known as floss-  flower and pussyfoot.</p><p>Agesilaus \3-je-s3-'la-9s\ II (b. c. 444 bc �d. 360, Cyrene, Cyrenaica)  King of Sparta (399-360) and commander of its army during most of the  era of Spartan supremacy (404-371). A member of the Eurypontid fam�  ily, he took the throne with Lysander�s help while Sparta was fighting Per�  sia. He defeated the allied Thebes, Athens, Argos, and Corinth in the  Corinthian War (395-387), despite losing some ground in central Greece  and a battle with the Persian fleet in 394. He dissolved the Boeotian  League, but battles against the Boeotian Confederacy (371) and Thebes  (370, 361) ended Sparta�s ascendancy. He died en route to Sparta from a  mercenary engagement in Egypt.</p><p>agglomerate No-'gla-mo-roA Large, coarse, angular rock fragments  associated with lava flow that are ejected during explosive volcanic erup�  tions. Although they may appear to resemble sedimentary conglomerates,  agglomerates are igneous rocks that consist almost wholly of angular or  rounded lava fragments of varying size and shape. Some geologists sort  agglomerates into bombs, blocks, and breccia. Bombs are ejected in a mol�  ten state, becoming rounded upon solidification, and blocks are erupted  as solid fragments. Upon accumulation and solidification of the angular  fragments (also known as pyroclastics), they form agglomerates.</p><p>aggressive behaviour Any action of an animal intended to injure  an opponent or prey animal or to cause an opponent to retreat. Aggres�  sion may be caused by various stimuli. Within its own group, an animal  must display aggressive postures to maintain its position within the hier�  archy (e.g., the pecking order of chickens). A threat by itself, as in ruffled  feathers or teeth revealed in a snarl, is usually sufficient to maintain an  already-established social order. Aggression often occurs just before mat�  ing season, when males win their choice of females and territories.</p><p>Agha Khan See Aga Khan</p><p>Aghlabid Vag-ls-bidX dynasty (800-909) Arab Muslim dynasty that  ruled Ifriqiyyah (Tunisia and eastern Algeria) through a succession of 11  emirs. Nominally subject to the �Abbasid dynasty, they in fact were inde�  pendent. High points of Aghlabid rule included the conquest of Sicily  (827-829), the flowering of their capital city, Kairouan (9th century), and  naval control of the central Mediterranean Sea. Public works included a  system for conserving and distributing water.</p><p>Agiads \'a-je-odz\ Line of Spartan kings named after Agis I (11th cen�  tury bc?). Agis was traditionally held to be the son of one of the legend�  ary twins who founded Sparta. Agis II (d. 400/398 bc) commanded the  Spartan army during most of the Peloponnesian War (431-404) against  Athens. Agis III (d. 331 bc) led the Greek cities in an unsuccessful revolt  against Alexander the Great. The last of the line was Agis IV (d. 241 bc),  who failed in his attempt to reform the unequal distribution of land and  wealth in Sparta, ultimately losing his crown and his life to Leonidas II.</p><p>Agincourt Va-jin-kort\, Battle of (October 25, 1415) Battle resulting  in the decisive victory of the English over the French in the Hundred Years'  War. In pursuit of his claim to the French throne, Henry V invaded Nor�  mandy with an army of 11,000 men in August 1415. The English took  Harfleur in September, but with their forces cut in half by battle and dis�  ease, they resolved to return to England. At Agincourt they were cornered  by a French army of 20,000-30,000 men, including many mounted  knights in heavy armor. On a cramped battlefield where the superior  French numbers offered little advantage, Henry made skillful use of his  lightly equipped, mobile archers. The French were disastrously defeated,  losing over 6,000 men, while the English lost fewer than 450.</p><p>aging Gradual change in an organism that leads to increased risk of  weakness, disease, and death. It takes place in a cell, an organ, or the total  organism over the entire adult life span of any living thing. There is a  decline in biological functions and in ability to adapt to metabolic stress.  Changes in organs include the replacement of functional cardiovascular  cells with fibrous tissue. Overall effects of aging include reduced immunity,  loss of muscle strength, decline in memory and other aspects of cognition,  and loss of colour in the hair and elasticity in the skin. In women, the pro�  cess accelerates after menopause.

Originally  described by the Marxist theorist Georgy Plekhanov and then by Vladimir  Ilich Lenin, it called for both emotional and reasoned arguments. The term,  a shortened form for the Agitation and Propaganda Section of the Com�  munist Party in the former Soviet Union, has been used in English, typi�  cally with a negative connotation, to describe any work�especially in  drama and other art forms�that aims to indoctrinate the public and  achieve political goals.</p><p>Agnes, Saint (fl. 4th century, Rome; feast day January 21) Legendary  Christian martyr, the patron saint of girls. According to tradition, she was  a beautiful virgin who turned away all suitors, declaring that she could  have no spouse but Jesus. The rejected suitors informed Roman officials  that she was a Christian, and she was punished by being exposed in a  brothel. There she was left miraculously unharmed; the only man who  attempted to violate her was struck blind, and she healed him with prayer.  She was later murdered during the persecutions ordered by Diocletian.</p><p>Agnew, Spiro T(heodore) (b. Nov. 9, 1918, Baltimore, Md.,  U.S.�d. Sept. 17, 1996, Berlin, Md.) U.S. politician, the only vice presi�  dent forced to resign. He studied law at the University of Baltimore and  began a law practice in a Baltimore suburb in 1947. He was elected Bal�  timore county executive in 1962 and then governor of Maryland in 1967.  In 1968 and 1972 he was elected vice president on the Republican ticket  headed by Richard Nixon. His sometimes colourful denunciations of Viet�  nam War protesters and other opponents of the Nixon administration  brought him much attention in the news media. Investigated for extortion,  bribery, and income-tax violations allegedly committed during his gov�  ernorship, he resigned the vice presidency in 1973 and pleaded no con�  test to a single income-tax charge. He was fined $10,000 and sentenced  to three years of unsupervised probation. Disbarred in 1974, he became a  consultant to foreign businesses.</p><p>Agni Hindu god of fire, second only to Indra in Vedic mythology. He is  the fire of the sun, of lightning, and of the hearth of worship, and is the  divine personification of the fire of sacrifice. He is thus the messenger  between human and divine orders. Agni is described as ruddy-hued and  with two faces, one beneficent and one malignant. In the Rig Veda he is  sometimes identified with Rudra, the forerunner of Shiva.</p><p>Agnon \ag-'non\, S.Y. orig. Shmuel Yosef Halevi Czaczkes (b.</p><p>July 17, 1888, Buczacz, Galicia, Austria-Hungary�d. Feb. 17, 1970,  Rehovot, Israel) Israeli writer. Bom into a Polish Galician family, Agnon  settled in Palestine in 1907 and chose Hebrew as his literary language.  The Day Before Yesterday (1945), perhaps his greatest novel, examines  the problem facing the Westernized Jew who immigrates to Israel. Other  works include the novels The Bridal Canopy (1919) and A Guest for the  Night (1938). He is regarded as one of the greatest modem Hebrew nov�  elists and short-story writers. In 1966 he and Nelly Sachs shared the Nobel  Prize for Literature.</p><p>agnosticism Vag-'nas-to-.siz-oirA Doctrine that one cannot know the  existence of anything beyond the phenomena of experience. It is popu�  larly equated with religious skepticism, and especially with the rejection  of traditional Christian beliefs under the impact of modern scientific  thought. T.H. Huxley popularized philosophical agnosticism after coining  the term agnostic (as opposed to gnostic) in 1869, to designate one who  repudiated traditional Judeo-Christian theism but was not a doctrinaire  atheist (see atheism). Agnosticism may mean no more than the suspension  of judgment on ultimate questions because of insufficient evidence, or it  may constitute a rejection of traditional Christian tenets.</p><p>agora Va-go-roV In ancient Greek cities, an open space serving as an  assembly area and backdrop for commercial, civic, social, and religious  activities. Use of the agora varied in different periods. Located in the  middle of the city or near the harbor, it was often enclosed by public  buildings, colonnades containing shops, and stoas for protection from sun  and bad weather. The highest honor for a citizen was to be granted a tomb  in the agora. See photograph on following page.</p><p>Agoracritus or Agorakritos \,a-g9-'rak-r3-t3s\ (fl. 5th century bc)  Greek sculptor.

Agoutis generally live  in forests and eat roots, leaves, and  fruit.</p><p>Agra \'a-gro\ City (pop., 2001:</p><p>1,275,134), west-central Uttar  Pradesh state, India. It was founded  by Sikandar Lodi in the early 16th  century on the Yamuna River southeast of Delhi and was intermittently the  Mughal capital. The city fell successively to the Jats and the Marathas in  the late 18th century and finally to the British in 1803. It is the site of the  Taj Mahal and the imperial tomb of Akbar.</p><p>Agra monte \a-gra-'mon-ta\ (y Simoni), Aristides (b. June 3,1868,  Camagiiey, Cuba�d. Aug. 19, 1931, New Orleans, La., U.S.) Cuban-bom  U.S. physician, pathologist, and bacteriologist. Reared in New York City,  he received his M.D. from Columbia University. He was a member of the  U.S. Army�s Reed Yellow Fever Board, which discovered in 1901 the role  of mosquitoes in transmitting yellow fever. As a professor at the Univer�  sity of Havana (1900-30), he became an influential leader of scientific  medicine in Cuba.</p><p>Agri Dagi See Mount Ararat</p><p>agribusiness Agriculture operated by business; specifically, that part  of a modem national economy devoted to the production, processing, and  distribution of food and fibre products and byproducts. Commercial farm�  ing has largely supplanted the family farm in production of cash crops.  Some food-processing firms that operate farms have begun to market fresh  produce under their brand names. In recent years, conglomerates involved  in nonagricultural businesses have entered agribusiness by buying and  operating large farms.</p><p>Agricola Vo-'gri-ko-loV Georgius orig. Georg Bauer (b. March 24,  1494, Clauchau, Saxony�d. Nov. 21, 1555, Chemnitz) German scholar  and scientist known as the father of mineralogy. A town physician in Sax�  ony (1527-33), he was among the first to found a natural science upon  observation as opposed to speculation. His De re metallica (1556) dealt  chiefly with mining and smelting; his De natura fossilium (1546), con�  sidered the first mineralogy textbook, presented the first scientific classi�  fication of minerals (based on their physical properties) and described  many new minerals, their occurrence, and mutual relationships.</p><p>Agricola No-'grik-o-bV Gnaeus Julius (b. June 13, ad 40, Forum  Julii, Gallia Narbonensis�d. Aug. 23, 93) Roman general. After Agricola  served as tribune and quaestor in Britain and Asia, Vespasian appointed  him governor of Britain (77/78-84). In that role he conquered parts of  Wales and northern England, then advanced into Scotland and set a fron�  tier between the Firths of Clyde and Forth. In 83 he crossed the Forth and  defeated the Caledonians at Mons Graupius; he then occupied Scotland  to the fringe of the Highlands, with forts at the main passes and a fortress</p><p>at Inchtuthil. Recalled to Rome, Agricola was offered the proconsulship  of Asia but chose retirement. His life is known through the writings of  his son-in-law Tacitus.</p><p>Agricultural Adjustment Administration (AAA) New Deal pro�  gram to restore U.S. agricultural prosperity during the Great Depression.  Established by an act of Congress in 1933, the AAA sought to curtail farm  production of certain staples, in order to raise prices. It also established  the Commodity Credit Corp., to make loans to farmers and to purchase  and store crops in order to maintain farm prices. The program had lim�  ited success before it was declared unconstitutional in 1936.</p><p>Agricultural Revolution Gradual transformation of the traditional  agricultural system that began in Britain in the 18th century. Aspects of  this complex transformation, which was not completed until the 19th cen�  tury, included the reallocation of land ownership to make farms more  compact and an increased investment in technical improvements, such as  new machinery, better drainage, scientific methods of breeding, and  experimentation with new crops and systems of crop rotation. The agri�  cultural revolution was an essential prelude to the Industrial Revolution.</p><p>agriculture Science or art of cultivating the soil, growing and harvest�  ing crops, and raising livestock. Agriculture probably first developed in  South Asia and Egypt, then spread to Europe, Africa, the rest of Asia, the  islands of the central and South Pacific, and finally to North and South  America. Agriculture in the Middle East is believed to date from 9000-  7000 bc. Early cultivated crops include wild barley (Middle East), domes�  ticated beans and water chestnuts (Thailand), and pumpkins (the  Americas). Domestication of animals occurred during roughly the same  period. Slash-and-burn land-clearing methods and crop rotation were  early agricultural techniques. Steady improvements in tools and methods  over the centuries increased agricultural output, as did mechanization,  selective breeding and hybridization, and, in the 20th century, the use of  herbicides and insecticides. More of the world�s aggregate manpower is  devoted to agriculture than to all other occupations combined.</p><p>agrimony Va-gro-.mo-neX Any plant of the genus Agrimonia, of the  rose family, especially A. eupatoria. This species is a herbaceous, hardy  perennial native to Europe but widespread in other northern temperate  regions, where it grows in hedge banks and the borders of fields. Its leaves  yield a yellow dye. The leaflets are oval with toothed margins; the small,  stalkless yellow flowers are borne in a long terminal spike. The fruit is a  tiny burr. A. gryposepala, a similar species, is widespread in the U.S.</p><p>Agrippa b-'grip-oX, Marcus Vipsanius (b. 63 bc? �d. March, 12  bc, Campania) Powerful deputy of  Augustus. He helped Octavian (later  Augustus) take power after Julius  Caesar�s murder (44 bc), defeating  Sextus Pompeius in 36 and Mark Ant�  ony at the Battle of Actium in 31. He  went on to quell rebellions, found  colonies, administer parts of the  empire, and give to Rome funds for  public works and buildings. In 23  Augustus seemed to make him heir,  and Agrippa married Augustus�s  daughter, Julia. His administrative  and military skills were particularly  directed to the eastern empire, where  in 15 he met with and made an ally  of Herod of Judaea. Agrippa�s writ�  ings (now lost) influenced Strabo  and Puny the Elder. His daughter  Agrippina the Elder (14? bc-ad 33)  was the wife of Germanicus Caesar,  mother of Caliguia and Agrippina the  Younger, and grandmother of Nero.</p><p>Agrippina X.ag-ri-'pI-noV the  Younger (b. ad 15�d. 59) Mother  of Nero and a major influence in the  early years of his reign. Daughter of  Agrippina the Elder (c. 14 bc-ad 33) and sister of Caugula, she was exiled  (39�41) for conspiring against Caligula. Her first husband, Gnaeus Domi-  tius Ahenobarbus, was Nero�s father.

He tried to murder her when she opposed one of his affairs,  and he finally had her put to death at her country house.</p><p>agrochemical Any chemical used in agriculture, including chemical  fertilizers, herbicides, and INSECTICIDES. Most are mixtures of two or more  chemicals; active ingredients provide the desired effects, and inert ingre�  dients stabilize or preserve the active ingredients or aid in application.  Together with other technological advances, including tractors, mechani�  cal harvesters, and irrigation pumps, agrochemicals have increased the  per-acre productivity of regions such as the Great Plains by 200-300%  since the 1930s. Their long-term effects on the environment and the sta�  bility of agricultural systems that use them are hotly debated.</p><p>agronomy Branch of agriculture that deals with field crop production  and soil management. Agronomists generally work with crops that are  grown on a large scale (e.g., small grains) and that require relatively little  management. Agronomic experiments focus on a variety of factors relat�  ing to crop plants, including yield, diseases, cultivation, and sensitivity to  factors such as climate and soil.</p><p>Aguan \a-'gwan\ River River, northern Honduras. It rises in the cen�  tral highlands west of Yoro, descends northeast to the coastal lowlands  for a distance of 150 mi (240 km), and empties into the Caribbean Sea  near Santa Rosa de Aguan. The lands along the river are used primarily  for agriculture but are susceptible to floods and hurricanes.</p><p>Aguascalientes \,a-gwas-kal-'yen-tas\ State (pop., 2000: 944,285),  central Mexico. With an area of 2,112 sq mi (5,471 sq km), it is one of  the country�s smallest states. It occupies part of the central plateau. It was  explored by Spaniards in the 16th century and became a colonial mining  centre. During the revolution of 1910-20 it was the scene of bitter fight�  ing. Today it is a fertile agricultural area and is noted for its mineral pro�  duction. Its capital is the city of Aguascalientes.</p><p>Aguascalientes City (pop., 2000: 594,056), capital of Aguascalientes  state, Mexico. Located on the Aguascalientes River, it was founded as a  mining settlement in 1575 and became the state capital in the 1850s. It is  sometimes called La Ciudad Perforada (�The Perforated City�) because of  an underground labyrinth of tunnels built by an unknown pre-Columbian  people. It is an agricultural centre, with several industries. Several notable  churches possess outstanding examples of colonial religious art.</p><p>March 23, 1869, near Cavite,</p><p>Aguinaldo \,a-ge-'nal-do\, Emilio (b  Luzon, Phil.�d. Feb. 6, 1964,</p><p>Manila) Philippine independence  leader. He was born of Chinese and  Tagalog parentage and was educated  at the University of Santo Tomas,</p><p>Manila. He became a leader of the  Katipunan, a revolutionary society  that fought the Spanish. Philippine  independence was declared in 1898,  and Aguinaldo became president, but  within months Spain signed a treaty  ceding the islands to the U.S. Agui�  naldo fought U.S. forces until he was  captured in 1901. After taking an oath  of allegiance to the U.S., he was  induced to retire from public life. He  collaborated with the Japanese dur�  ing World War II. After the war he  was briefly imprisoned; released by  presidential amnesty, he was vindicated by his appointment to the Council  of State in 1950. In his later years he promoted nationalism, democracy,  and improvement of relations between the U.S. and the Philippines.</p><p>Emilio Aguinaldo.</p><p>BROWN BROTHERS</p><p>Agulhas \3-'g3l-9s\, Cape Cape, southernmost point of the African  continent. Its name, Portuguese for �needles,� refers to the rocks and reefs  that have wrecked many ships.

Rising in the  southeast and flowing north 240 mi (390 km) to enter Butuan Bay of the  Bohol Sea, it forms a fertile valley 40-50 mi (65-80 km) wide between  the Central Mindanao Highlands and the Pacific Cordillera. It is navigable</p><p>for 160 mi (260 km). Despite early Spanish contacts in the 17th century,  most of the valley has remained sparsely settled by native peoples.</p><p>Ahab Ya- ,hab\ (fl. 9th century bc) Seventh king of the northern kingdom  of Israel (r. c. 874-853 bc). He inherited a realm that included territory  east of the Jordan River, in Gilead and probably Bashan, and also the  tributary kingdom of Moab. His marriage to Jezebel revived an alliance  with the Phoenicians, but her efforts to establish Baal worship provoked  bitter opposition from Elijah. Ahab�s reign was dominated by a fierce bor�  der war with Syria; he died in an attempt to recover Ramoth-Gilead from  the Syrians.</p><p>Ahaggar Vo-'ha-gor, ,a-h9-'gar\ or Hoggar Vhag-or, o-'gar\ Moun�  tains High plateau region, southern Algeria. Located in the central  Sahara, it extends about 970 mi (1,550 km) from north to south and 1,300  mi (2,100 km) from east to west. Its mean elevation is above 3,000 ft  (900 m); its highest peak is Mount Tahat (9,573 ft [2,918 m]). The main  caravan route to Kano (Nigeria) passes along its western margin.</p><p>Ahidjo Xa-'hi-joV, Ahmadou (b. August 1924, Garoua, Cameroon�d.  Nov. 30, 1989, Dakar, Senegal) First president of Cameroon, 1960-82.  He presided over one of the few successful attempts at African unity: the  joining of the southern half of the former British Cameroons with the  larger French-speaking Cameroun. In 1982, after managing to build up a  stable, relatively prosperous nation (through single-party rule), he went  into exile after being implicated in a plot against his successor, Paul Biya.</p><p>ahimsa \o-'him-sa\ (Sanskrit: �noninjury�) Fundamental ethical virtue  of Jainism, also respected in Buddhism and Hinduism. In Jainism ahimsa is the  standard by which all actions are judged. It requires a householder observ�  ing the small vows ( anuvrata ) to refrain from killing any animal life. An  ascetic observing the great vows ( mahavrata ) is expected to take the great�  est care not to injure any living substance, even unknowingly. To do so  interrupts that being�s spiritual progress and increases one�s own karma,  delaying liberation from the cycle of rebirth. In the 20th century Mohan�  das K. Gandhi extended ahimsa into the political sphere as satyagraha.</p><p>Ahmad, MTrza Ghulam See Mirza Ghulam Ahmad</p><p>Ahmad ibn Hanbal Vak-mod-.ib-sn-'kan-bolV (b. 780, Baghdad,  Iraq�d. 855, Baghdad) Muslim theologian and jurist. He began to study  the Had]th (Traditions) at age 15. He traveled widely to study with the  great masters and made five pilgrimages to Mecca. In 833-835 he bravely  endured floggings and imprisonment rather than subscribe to the Mu'tazilI  doctrine of a created (rather than eternal) Qur�an, and he is remembered  as a staunch upholder of Muslim traditionalism. He compiled the Tradi�  tions of Muhammad and is the eponym of the Hanbal! school, the most  traditional of the four orthodox Islamic schools of law. Opposing codi�  fication of the law, he believed jurists needed the freedom to derive legal  solutions from the Qur�an and the sunna. He is revered as one of the  fathers of Islam.</p><p>Ahmad Khan Vam-ad-'kanV, Sir Sayyid (b. Oct. 17, 1817, Delhi�d.  March 27, 1898, Aligarh, India) Indian educator and jurist. Born into a  family of officials in the Mughal dynasty, he worked for the British East  India Co. and held various judicial posts. He supported the British in the  1857 Indian Mutiny but criticized their errors in his influential pamphlet  Causes of the Indian Revolt. His other works include Essays on the Life  of Mohammed (1870) and commentaries on the Bible and Qur�an. He  founded schools at Muradabad and Ghazipur, established the Scientific  Society, sought to strengthen the Muslim community through the reform  journal Tahdhib al-Akhlaq, and was active in founding a Muslim college,  the Anglo-Mohammedan Oriental College, in 1877 at Aligarh.</p><p>Ahmad Shah Durrani Vak-mod-'sha-dur-'a-neN (b. c. 1722, Multan,  Punjab�d. Oct. 16?, 1772, Toba Ma'ruf, Afg.) Founder of modem  Afghanistan. The son of an Afghan chief, he became shah in 1747 on the  death of the Persian conqueror Nadir Shah, in whose army he had served.  He proceeded to invade India nine times over the next 22 years in an  attempt to control the trade routes between northern India and central and  western Asia and became ruler of an empire that extended from the Amu  Darya to the Indian Ocean and from Khorasan to present-day northern  India. His hold on the Punjab, governed by his son Timur Shah, was  weakened by rebellions at home, and he ultimately lost control of it to the  Sikhs. Much of his empire disintegrated after his death.</p><p>Ahmad Sirhindi \sir-'hin-de\ (b. 1564?, Sirhind, Patiala, India�d.  1624, Sirhind) Indian mystic and theologian who is responsible for the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Ahmadiyyah &#x25BA; Alley I 31</p><p>revival of Sunnite Islam in India. He traced his descent from �Umar ibn  al-Khattab. After a traditional Muslim education, he joined an important  Sufi order and devoted himself to preaching against the tendencies of  Akbar and his successor, Jahangir, toward pantheism and ShT'ite Islam. His  views are outlined in his most famous work, Maktubat, a compilation of  his letters. His burial place at Sirhind is a site of pilgrimage.</p><p>Ahmadiyyah X.ah-mo-'de-oX Islamic sect, founded in India in 1889 by  MIrza Ghulam Ahmad. It holds that Jesus feigned death and resurrection  and escaped to India and that jihad is a peaceful battle against nonbeliev�  ers. Following the death of Ghulam Ahmad�s successor (1914), the  Ahmadiyyah split. The Qadiani, based in Rabwah, Pak., recognize Ghu�  lam Ahmad as a prophet; they are zealous missionaries, preaching Ahmadi  beliefs as the one true Islam. A Lahore-based sect regards Ghulam Ahmad  merely as a reformer and seeks to make converts to Islam generally. The  term Ahmadiyyah is also used to describe various Sufi orders (see Sufism),  particularly that founded by Ahmad al-Badaw! (d. 1276). One of the most  popular orders in Egypt, it has branches throughout the Islamic world.</p><p>Ahmadu Seku Xa-'mad-ii-'sa-kuX (d. 1898, Sokoto, Northern Nigeria)  Second and last ruler of the Tukulor empire in West Africa. Succeeding  his father, al-Hajj �Umar, in 1864, Ahmadu ruled over a great empire cen�  tred on the ancient Bambara kingdom of Segu, in present Mali. In 1887  he was forced to abandon Segu and accept French protectorate status. By  1891 most of his strongholds had been seized.</p><p>Ahmed Yesevi Xak-'met-.ye-se-'veX or Ahmad Yasawi</p><p>Xak-'med-.ya-sa-'veX (b. 11th century, Sayram�d. 1166, YasI, Turkistan)  Turkish poet and Sufi mystic. When he was young his family moved to  YasI, where he began his teaching. The Book of Wisdom, a collection of  mystical poetry, is traditionally attributed to him. He established a mys�  tical order whose rituals preserved Islamic and ancient Turco-Mongol  customs, and promoted the spread of mysticism throughout the Turkish�  speaking world. His poetry influenced Turkish literature and led to the  development of mystical folk literature. He was revered as a saint, and  Timur erected a magnificent mausoleum over his grave in 1397/98.</p><p>Ahmedabad Va-mo-do-.badX or Ahmadabad City (pop., 2001:  metro, area, 4,525,013), Gujarat state, west-central India. It is located on  the Sabarmati River 275 mi (440 km) north of Mumbai (Bombay). Founded  in 1411 by Sultan Ahmad Shah, Ahmedabad reached its height later that  century but subsequently declined. It was revived under Mughal emper�  ors in the 17th century and came under British rule in 1818. With the  opening of cotton mills in the mid-19th century, it became India�s largest  inland industrial centre. The city is associated with Indian nationalism;  Mohandas K. Gandhi�s political agitation began there in 1930. In 2001 the  city was struck by a violent earthquake that took many lives.</p><p>Alisa*? \ak-'sa-e\, Ahmad al- in full Shaykh Ahmad ibn Zayn  al-DTn Ibrahim al-Ahsa�I (b. 1753, Al-Hasa, Arabia�d. 1826, near  Medina) Founder of the heterodox ShTite Muslim ShaykhI sect of Iran.  He traveled widely in Persia and the Middle East. In 1808 he settled in  Yazd, Persia, where he attracted followers with his interpretation of  Shfism. He claimed knowledge from visions of Muhammad and the imams  and contended that the imams were originally beings of divine light who  participated in the creation of the world. Orthodox ShTite theologians  declared him an apostate in 1824; he died two years later on pilgrimage  to Mecca, but the ShaykhI sect survived him.</p><p>Ahura Mazda Va-hur-o-'maz-doX Supreme god of ancient Iranian reli�  gion, especially Zoroastrianism. Ahura Mazda was worshiped by Darius I  and his successors as the greatest god and the protector of the just king.  Zoroaster taught that Ahura Mazda created the universe and maintains  the cosmic order, and that the history of the world consists of the battle  between two spirits he created�the beneficent Spenta Mainyu and the  destructive Angra Mainyu. The Avesta identifies Ahura Mazda himself  with the beneficent spirit and represents him as bountiful, all-knowing,  and the creator of everything good. In late sources (from the 3rd century),  Zurvan (�Time�) is the father of the twins Ormazd (Ahura Mazda) and  Ahriman (Angra Mainyu), who in orthodox Mazdaism (Zoroastrianism  and Parsiism) reign alternately over the world until Ormazd�s ultimate  victory.</p><p>Ai \'a-,I\ Town, eastern Canaan, ancient Palestine. In the Bible (Joshua  7-8), it was destroyed by the Israelites under Joshua. Biblical references  agree in locating Ai just east of Bethel (modern Bay tin) in the West Bank,  at the Early Bronze Age site now called Al-Tall. Excavations at Ai in</p><p>1933-35 uncovered a temple of the 3rd millennium bc. The biblical events  at Ai are assigned to the period c. 1400-1200 bc, when evidence indicates  it was not in fact occupied; early tradition may have identified the Canaan-  ite town under Bethel with the nearby ruins of Al-Tall.</p><p>Aidan \'ad- 3 n\, Saint (b.

He was a monk at Iona in Scotland when King  Oswald of Northumbria requested that he be made bishop of the newly  converted Northumbrians. He established his church, see, and monastery  on the island of Lindisfarne, not far from the royal stronghold of Bam�  burgh. From there he evangelized northern England, founding churches,  monasteries, and a school. Bede praised him for his learning, charity, and  simplicity of life.</p><p>aide-de-camp \,ad-di-'kamp\ Officer on the personal staff of a gen�  eral, admiral, or other high-ranking commander who acts as a confiden�  tial secretary.

AIDS is the last stage  of HIV infection, during which time the individual develops frequently  fatal infections and cancers, including Pneumocystis carinii pneumonia,  cytomegalovirus (C MV), lymphoma, and Kaposi sarcoma. The first AIDS  cases were identified in 1981, HIV was isolated in 1983, and blood tests  were developed by 1985. According to the UN�s 2004 report on AIDS,  some 38 million people are living with HIV, approximately 5 million  people become infected annually, and about 3 million people die each year  from AIDS. Some 20 million people have died of the disease since 1981.  Sub-Saharan Africa accounts for some 70 percent of all HIV infections.  Rates of infection are lower in other parts of the world, but the epidemic  is spreading rapidly in eastern Europe, India, South and Southeast Asia,  Latin America, and the Caribbean.</p><p>Aiken Va-konX, Conrad (Potter) (b. Aug. 5, 1889, Savannah, Ga.,  U.S.�d. Aug. 17, 1973, Savannah) U.S. writer. Aiken was traumatized as  a child when his father killed Aiken�s mother and then himself. Educated  at Harvard University, Aiken wrote most of his fiction in the 1920s and  �30s. His works are influenced by early psychoanalytic theory. Generally  more successful than his novels were his short stories, notably �Strange  Moonlight� from Bring! Bring!

The first, used by  trains, trucks, and buses, operates by a piston driven by compressed air  from reservoirs connected to brake cylinders (see piston and cylinder).  When air pressure in the brake pipe is reduced, air is automatically admit�  ted into the brake cylinder. The first practical air brake for railroads was  invented in the 1860s by George Westinghouse. The second type, used by  aircraft and race cars, consists of a flap or surface that can be mechani�  cally projected into the airstream to increase the resistance of the vehicle  to air and lower its speed.</p><p>air-conditioning Control of temperature, humidity, purity, and motion  of air in an enclosed space, independent of outside conditions. In a self-  contained air-conditioning unit, air is heated in a boiler unit or cooled by  being blown across a refrigerant-filled coil and then distributed to a con�  trolled indoor environment. Central air-conditioning in a large building  generally consists of a main plant located on the roof or mechanical floor  and intermittently spaced air-handling units, or fans that deliver air  through ducts to zones within the building. The air then returns to the  central air-conditioning machinery through spaces called plenums to be  recooled (or reheated) and recirculated. Alternate systems of cooling use  chilled water, with water cooled by a refrigerant at a central location and  circulated by pumps to units with fans that circulate air locally.</p><p>air-cushion vehicle or hovercraft Vehicle supported above the  surface of land or water by an air cushion, produced by downwardly  directed fans, enclosed within a flexible skirt beneath the hull. The con�  cept was first proposed by John Thornycroft in the 1870s, but a working  model was not produced until 1955, when Christopher Cockerell solved  the problem of keeping the air cushion from escaping from under the  vehicle, and formed Hovercraft Ltd. to manufacture prototypes. Problems  with skirt design and engine maintenance have restricted the vehicle�s  commercial application; today hovercraft are used mainly as ferries.</p><p>air force Military organization that has the primary responsibility for  conducting air warfare. The air force must gain control of the air, support  ground forces (e.g., by attacking enemy ground forces), and accomplish  strategic-bombing objectives. Its basic weapons platforms are fighters,  bombers, attack aircraft, and early warning and control aircraft. Since the  mid-20th century, some air forces have also been responsible for land-  based nuclear missiles as well as nuclear-armed bombers. The army and  naval branches of a state�s armed forces may also operate aircraft.</p><p>Air France in full Compagnie Internationale Air France</p><p>French passenger and cargo airline with more than 200 destinations in  some 80 countries.

The French government began privatizing the former national air�  line in July 2002. In 2004 Air France acquired the Dutch airline KLM to  create Air France-KLM, one of the largest air carriers in the world. The  two airlines, however, continued to operate as separate companies, retain�  ing their own hubs, flights, and logos.</p><p>air mass In meteorology, a large body of air having nearly uniform  conditions of temperature and humidity at any given altitude. Such a mass  has distinct boundaries and may extend hundreds or thousands of miles  horizontally and sometimes as high as the top of the troposphere. An air  mass forms whenever the atmosphere remains in contact with a large,  relatively uniform land or sea surface long enough to acquire its tempera�  ture and moisture properties. The Earth�s major air masses all originate  in polar or subtropical latitudes. The middle latitudes constitute essen�  tially a zone of modification, interaction, and mixing of the polar and  tropical air masses.</p><p>air pollution Release into the atmosphere of gases, finely divided sol�  ids, or finely dispersed liquid aerosols at rates that exceed the capacity of  the atmosphere to dissipate them or to dispose of them through incorpo�  ration into the biosphere. Dust storms in desert areas and smoke from for�  est and grass fires contribute to particulate and chemical air pollution.  Volcanic activity is the major natural source of air pollution, pouring huge  amounts of ash and toxic fumes into the atmosphere. Air pollution may  affect humans directly, causing irritation of the eyes or coughing. More  indirectly, its effects can be measured far from the source, as, for example,  the fallout of tetraethyl lead from automobile exhausts, which has been  observed in the oceans and on the Greenland ice sheet. Still less direct  are possible effects on global climates. See also smog.</p><p>air warfare Military operations conducted by airplanes, helicopters,  or other aircraft against aircraft or targets on the ground and in the water.  Air warfare did not become important until World War I (1914-18). The  British, French, German, Russian, and Italian armed forces had flying  units, including biplanes armed with machine guns for �dogfights� with  enemy fighter aircraft. Zeppelins and larger airplanes carried out bombing  raids. The 1920s and �30s saw the development of the monoplane, the  all-metal fuselage, and the aircraft carrier. During World War II (1939�  45), the Battle of Britain was the first fought exclusively in the air, the  Battle of the Coral Sea was the first between carrier-based aircraft, and  the atomic bombings of Hiroshima and Nagasaki were the first use of</p><p>Ainu \'I-nii\ Indigenous people of what is now Japan.

Once physically and cultur�  ally distinct from the Japanese, their  origins and their role in Japanese his�  tory and prehistory have been the  subject of scholarly debate. Many  contemporary Ainu claim some con�  nection to the prehistoric Jomon cul�  ture. The Ainu language, which has  no known relationship to any other  language, is virtually extinct, being  supplanted by Japanese. The Ainu  were traditionally hunters, fisher�  men, and trappers; their religion cen�  tred on spirits believed to be present  in animals and the natural world.</p><p>air Mixture of gases constituting the  earth�s atmosphere. Some gases  occur in steady concentrations. The  most important are molecular nitro�  gen (N 2 ), 78% by volume, and  molecular oxygen (0 2 ), 21%. Small amounts of argon (Ar; 1.9%), neon  (Ne), helium (He), methane (CH 4 ), krypton (Kr), hydrogen (H 2 ), nitrous  oxide (N 2 0), and xenon (Xe) are also present in almost constant propor�  tions. Other gases occur in variable concentrations: water vapour (H 2 0),  ozone (0 3 ), carbon dioxide (C0 2 ), sulfur dioxide (S0 2 ), and nitrogen  dioxide (N0 2 ). Air also contains trace amounts of ammonia and hydro�  gen sulfide. The variable constituents are important for maintaining life.  Water vapour is the source for all forms of precipitation and is an impor�  tant absorber and emitter of infrared radiation. Carbon dioxide is neces�  sary for photosynthesis and is also an important absorber and emitter of  infrared radiation. Ozone in the stratosphere (see ozone layer) is an effec�  tive absorber of ultraviolet radiation from the Sun but at ground-level is  a corrosive pollutant and a major constituent of smog.</p><p>Ainu couple in ceremonial dress, Hok�  kaido, Japan.</p><p>COURTESY OF THE CONSULATE GENERAL OF JAPAN, NEW  YORK CITY</p><p>Ailly \a-'ye\, Pierre d' (b. 1350,</p><p>Compiegne, Fr.�d.

European aircraft manufacturer that is the world�s sec�  ond largest maker of commercial aircraft (after Boeing Co.). It is co-owned  by the German-French-Spanish European Aeronautic Defence and Space  Company (EADS), with an 80% interest, and Britain�s BAE Systems, with  20%. Airbus was formed as a consortium in 1970 by French and German  aerospace firms (later joined by Spanish and British companies) to fill a  market niche for short- to medium-range, high-capacity jetliners and to  compete with long-established American manufacturers. Its first product,  the A300, entered service in 1974. It was the first wide-body jetliner  equipped with only two engines for more economical operation. The twin-  engine A320 (entered service 1988) incorporated numerous technical  innovations, notably fly-by-wire (electric rather than mechanically  linked), computer-based flight controls. The four-engine A340 (1993) and  smaller, twin-engine A330 (1994) were long-range airliners. In 2000 Air�  bus launched development of the A380, intended to be the world�s larg�  est passenger jet with a typical seating of 555 people. The consortium  integrated into a single company in 2001.</p><p>aircraft carrier Naval vessel equipped with a platform that allows air�  planes to take off and land. Takeoffs are facilitated by the use of catapults  or by a ramp at the end of the flight deck. For landing, aircraft are fitted  with retractable hooks that engage arresting wires on the deck, or they are  built with vectored-thrust engines that allow them to be landed vertically.  Britain�s Royal Navy developed the first true aircraft carrier near the end  of World War I, and carriers played leading roles in World War II naval  engagements such as the Pearl Harbor attack and the Battles of Midway  and the Coral Sea. The largest modern carriers are 1,000-ft (300-m)  nuclear-powered vessels of the U.S. Navy, which can carry 100 jet air�  craft. Other types include the light carrier, equipped for anti-submarine  warfare and ground attack, and the helicopter carrier, intended for con�  ducting amphibious assault.</p><p>airplane Fixed-wing aircraft that is heavier than air, propelled by a  screw propeller or a high-velocity jet, and supported by the dynamic reac�  tion of the air against its wings. An airplane�s essential components are  the body or fuselage, a flight-sustaining wing system, stabilizing tail sur�  faces, altitude-control devices such as rudders, a thrust-providing power  source, and a landing support system. Beginning in the 1840s, several  British and French inventors produced designs for engine-powered air�  craft, but the first powered, sustained, and controlled flight was only  achieved by Wilbur and Orville Wright in 1903. Later airplane design was</p><p>affected by the development of the jet engine; most airplanes today have  a long nose section, swept-back wings with jet engines placed behind the  plane�s midsection, and a tail stabilizing section. Most airplanes are  designed to operate from land; seaplanes are adapted to touch down on  water, and carrier-based planes are modified for high-speed short takeoff  and landing. See also airfoil; aviation; glider; helicopter.</p><p>wing</p><p>Two physical forces essential to airplane flight are thrust and lift. Jet engines, such  as the turbofan shown, provide forward thrust by taking in air through the front of  the engine, compressing it, and burning it with fuel in the combustor. Hot exhaust  gases and air are then expelled at high speed from the rear of the engine. Lift is  generated by the flow of air past the wings. Air flowing over the rounded upper  surface of a wing moves faster than air flowing past the flat lower surface; as a  result, the air above the wing exerts a lower pressure than the air below, producing  a net upward force, or lift. Both lift and drag (friction caused by the plane moving  through air) can be adjusted by the movement of ailerons, landing flaps, and tabs  on the wings' edges. At the rear of the plane, the elevator, located on the horizon�  tal stabilizer, controls the airplane's movement around the lateral axis. Both the  elevator and the rudder, located on the vertical stabilizer, help to control turning  movements initiated by the ailerons.</p><p>� MERRIAM-WEBSTER INC.</p><p>airport Site and installations for the takeoff and landing of aircraft. Early  airports were open, grass-covered fields, called landing fields, that  allowed a pilot to head directly into the wind to aid a plane�s lift on take�  off and to decrease its speed on landing.

Akbar,  whose ancestors included Timur and Genghis Khan, ascended the throne as  a youth. Initially his rule extended only over the Punjab and the area  around Delhi. The Rajput raja of Amber (Jaipur) acknowledged his suzer�  ainty in 1562, and other Rajput rajas followed suit. Akbar included Rajput  princes and other Hindus in the highest ranks of his government and  reduced discrimination against non-Muslims. He continued his conquests,  taking Gujarat in the west (1573) and Bengal in the east (annexed in  1576). Toward the end of his reign he conquered Kashmir (1586) and  moved south into the Deccan. Administratively, he strengthened central  power, establishing that all military officers and civil administrators were  to be appointed by the emperor. He encouraged scholars, poets, painters,  and musicians, making his court a centre of culture. He had Sanskrit clas�  sics translated into Persian and was enthusiastic about the European paint�  ings presented to him by Jesuit missionaries.

Soon after the Revo�  lution of 1917, Soviet authorities  condemned her work for what they  perceived as its narrow preoccupa�  tion with love and God, and in 1923,  after the execution of her former hus�  band on conspiracy charges, she  entered a long period of literary  silence. After World War II she was  again denounced and expelled from  the Writers Union. Following Joseph  Stalin�s death in 1953, she was  slowly rehabilitated. In her later  years she became the influential cen�  tre of a circle of younger Russian poets. Her longest work, Poem With�  out a Hew, is regarded as one of the great poems of the 20th century.  Regarded today as one of the greatest of all Russian poets, she is also  admired for her translations of other poets� works and for her memoirs.</p><p>Akiba ben Joseph Xa-'ke-va-ben-'jo-zofX (b. ad 40�d. c. 135, Cae�  sarea, Palestine) Jewish sage, one of the founders of rabbinic Judaism. He  is said to have been an illiterate shepherd who began to study after age  40. He believed that Scripture contained many implied meanings in addi�  tion to its overt meaning, and he regarded written law (Torah) and oral  law (Halakhah) as ultimately one. He collected and systematized the oral  traditions concerning the conduct of Jewish social and religious life, thus  laying the foundation of the Mishna. He may have been involved in Bar  Kokhba�s unsuccessful rebellion against Rome; he gave the rebel leader  his title and recognized him as the Messiah. He was imprisoned by the  Romans and martyred for his public teaching. See also Ishmael ben Elisha.</p><p>Akihito \a-'ke-he-,to\ or Heisei \'ha-'sa\ emperor (b. Dec. 23, 1933,  Tokyo, Japan) Emperor of Japan from 1989. Son of Hirohito, his role, like  that of his father after 1945, has been largely ceremonial. He is the first  Japanese emperor to have married a commoner, in what was hailed at the  time as a love match rather than the customary arranged marriage. His  children are Crown Prince Naruhito, Prince Akishino, and Princess Nori.</p><p>Akita \o -'ke-to\ Breed of working dog that originated in the mountains  of northern Japan. In 1931 the Japanese government designated the breed  as a national treasure. It is a powerful, muscular dog with a broad head,  erect pointed ears, and a large curved tail carried over the back or curled  against the flank. Colours and markings vary, including all-white, brindle,  and pinto. All but the white akitas bear a distinct mask (dark area around  the muzzle). Males stand 26-28 in. (66-71 cm) high, females 24-26 in.  (60-66 cm).</p><p>Akkad Va -kad\ Ancient region, central Iraq. Akkad was the northern  division of ancient Babylonia (Sumer was the southern division). Its name  was taken from the city of Agade, founded by the conqueror Sargon c.  2300 bc. Sargon united the city-states in the region and extended the  empire to much of Mesopotamia, including Sumer, Elam, and the upper  Tigris. The empire waned in the 22nd century bc. Under the kings of  Akkad, their Semitic language, Akkadian, became a literary language, and  great art was fostered.</p><p>Akkadian Xo-'ka-de-onX language &lt;?/ Assyro-Babylonian lan�  guage Semitic language spoken in Mesopotamia in the 3rd-lst millen�  nia bc. It is known from a great many inscriptions, seals, and clay tablets  in cuneiform writing. Akkadian supplanted Sumerian as the major spoken  language of southern Mesopotamia by 2000 bc and about this time split  into an Assyrian dialect spoken in the northeast and a Babylonian dialect  spoken in the south. Akkadian died out as a vernacular in the first half of  the 1st millennium bc, being effectively replaced by Aramaic in Meso�  potamia, though it continued to be written until about the 1st century ad.</p><p>�Akko Va -ko\ or Acre X'a-kro, 'a-korX Seaport town (pop., 2000 est.:  45,737), northwestern Israel. First mentioned in an Egyptian text from the  19th century bc, it was long a Canaanite and Phoenician city. After its  conquest by Alexander the Great (336 bc), it was a Greek polity (called  Philadelphus), and for several centuries it remained part of the Roman  Republic and Empire. The Persians (614) and Arabs (638) conquered the  town, but it was ruled by the Turkish SeuOq dynasty when the Crusaders  captured it in 1104. The Crusaders renamed the city St. Jean d�Acre and  made it their last capital (see Crusades). Except for brief intervals, it was  under the rule of the Ottoman Empire from 1516 until British forces took  it in 1918. It was part of Palestine under the British mandate and became  part of Israel in 1948, when most of its Arab inhabitants fled. Notable  structures include the Great Mosque and the Crypt of St. John. It is the  burial place of Baha� Ullah, the founder of the Baha�i faith.</p><p>Akmola See Astana</p><p>Akron City (pop., 2000: 217,074), northeastern Ohio, U.S., on the Cuya�  hoga River. At 1,200 ft (370 m) above sea level, Akron was named for its  �high place� (Greek: acros) on the watershed between the Mississippi River  and the Great Lakes. Laid out in 1825, the town was assured substantial  growth by the completion of two canals (1827, 1840). The abundant water  supply and the arrival of the railroads prompted Benjamin Franklin Goo�  drich to move a rubber factory there in 1871. Akron became known as  �rubber capital of the world,� although by the 21st century much pro�  duction had moved from the area.</p><p>Aksum or Axum X'ak-.siimX Ancient kingdom, northern Ethiopia. At  its apogee (3rd-6th century ad), Aksum merchants traded as far as Alex�  andria and beyond the Nile River. The modern town of Aksum (pop., 1994:  27,148), once the kingdom�s capital, is a religious centre best known for  its antiquities. It has long been regarded as a holy city for the Ethiopian  Orthodox church; according to tradition, King Menilek I, son of Solomon  and the Queen of Sheba, brought the Ark of the Covenant there from  Jerusalem. Aksum�s antiquities have made it a tourist centre.</p><p>Akwamu X'ak-wa-miiX Historical state of western Africa�s Gold Coast  (now Ghana). Founded by an Akan people c. 1600, it grew rich on the  sale of gold. At its height in the early 18th century, Akwamu stretched  more than 250 mi (400 km) along the coast, from Whydah (now Ouidah,  Benin) in the east to beyond Winneba (now in Ghana) in the west. By  1710 the state was being pressured by other groups (including the Asante)  that had grown powerful in the area, and by 1731 it had ceased to exist.</p><p>Al Among Arab groups, a term denoting a tribe, clan, family, or other  patrilineal filiation.

Covering 51,718 sq mi (133,950 sq km), its capital  is Montgomery. Its original inhabitants included Cherokee, Chickasaw,  Choctaw, and Creek Indians; evidence of their activity can be found near  Tuscaloosa. Hernando de Soto traveled there, and the French founded a  settlement at Fort Louis in 1702. The Alabama Territory was created in  1817, and statehood was granted in 1819. Alabama seceded from the  Union in 1861, becoming part of the Confederacy; it was readmitted in  1868. Efforts during Reconstruction to include blacks in government  failed, and Alabama remained segregationist until the 1960s. Dependent  on cotton until the early 20th century, the state has since diversified its  agricultural production and developed industrially, especially at Birming�  ham; Mobile has become a major ocean terminal.</p><p>Alabama claims U.S. maritime grievances against Britain in the  American Civil War. Although Britain had declared official neutrality in  the war, it allowed the Confederate cruiser Alabama , which later  destroyed 68 Union ships, to be constructed in England. U.S. ambassa�  dor Charles Francis Adams demanded that the British take responsibility  for these damages, and he advocated arbitration to settle the matter. In  May 1871 the parties signed the Treaty of Washington, which established  certain wartime obligations of neutrals. The tribunal also held Britain  liable for losses and awarded the U.S. damages of $15.5 million.</p><p>Alabama River River, southern Alabama, U.S. Formed by the Coosa  and Tallapoosa rivers northeast of Montgomery, it winds westward to  Selma and then flows southward. The river�s navigable length is 305 mi  (491 km). It is joined above Mobile by the Tombigbee River to form the  Mobile and Tensaw rivers, which flow into Mobile Bay. Mobile and Mont�  gomery became major cities largely because they were on this important  artery.</p><p>alabaster Fine-grained gypsum that has been used for centuries for  statuary, carvings, and other ornaments. It normally is snow-white and  translucent but can be artificially dyed; it may be made opaque and simi�  lar in appearance to marble by heat treatment.

The alabaster of  the ancients was a brown or yellow onyx marble.</p><p>Alaca Huyuk V.a-la-'ja-hoe-.yiBkX Ancient Anatolian site, north-central  Turkey. It lies northeast of the old Hittite capital of Bogazkoy. Traces of  a Hittite building were found in the early 20th century and below them a  royal necropolis of tombs from c. 2500 bc. There is evidence of the  advanced accomplishments of Copper Age metallurgy in the form of jew�  elry, bowls, and jugs. Though the ethnic identity of the preliterate inhab�  itants is uncertain, they probably belonged to the non-Indo-European  population that preceded the Hittites.</p><p>Aladdin Hero of a well-known story in The Thousand and One Nights.

He was placed on the throne by the imperial vizier Imad  al-Mulk Ghazi al-Dln and was always the puppet of more powerful men,  including the Afghan ruler Ahmad Shah Durrani, whose agents occupied  Delhi in 1757 and made Alamglr the nominal emperor of Hindustan. He  was murdered by Ghazi al-Dln, who feared Alamglr might be captured  and used against him in another Afghan invasion.</p><p>Alamo Eighteenth-century mission in San Antonio, Texas, site of a his�  toric siege of a small group of Texans by a Mexican army (1836) during  the Texas war for independence from Mexico. The abandoned mission  was occupied occasionally by Spanish troops, who named it the Alamo</p><p>(�cottonwood�) after the surrounding trees. At the start of the war in  December 1835, volunteers occupied the Alamo and vowed to fight to the  death any attempt to recapture it. In February 1836 a Mexican army of  several thousand began a siege that lasted 13 days. The Texan force of  about 180, led by Jim Bowie and including Davy Crockett, was overrun;  nearly all the defenders were killed (about 15 persons, mostly women and  children, were spared). Mexican casualties were at least 600. �Remem�  ber the Alamo!� became a rallying cry for Texans through the remainder  of the war.</p><p>Alanbrooke (of Brookeborough), Alan Francis Brooke, 1 st  Viscount (b. July 23, 1883, Bagneres-de-Bigorre, France�d. June 17,  1963, Hartley Wintney, Hampshire, Eng.) British military leader. He  served in World War I and later became director of military training  (1936-37) and an expert on gunnery. In World War II he began as com�  mander of a corps in France and covered the Dunkirk evacuation. After  serving as commander of the British home forces (1940-41), he was pro�  moted to chief of staff (1941�46). He established good relations with the  U.S. forces and exercised a strong influence on Allied strategy. He was  promoted to field marshal in 1944 and created a viscount in 1946.</p><p>Aland \'o-,lan\ Islands Archipelago, southwestern Finland, constitut�  ing Ahvenanmaan autonomous kunta (commune).

Aland, the  largest island, is the location of Mariehamn, the administrative capital and  chief seaport. The islands were Christianized by 12th-century Swedish  missionaries. When Finland declared its independence in 1917, the  Alanders sought to become part of Sweden. Though the archipelago  remains with Finland, it has been given unique autonomy.</p><p>alanine Va-lo-nenN Either of two organic compounds.

He twice led invasions of Italy, the second time extorting a large  payment from the Roman Senate. Alaric�s forces grew after the Romans  massacred the wives and children of Visigoths serving in the Roman army.  He besieged Rome (408, 409), proclaiming Priscus Attalus as Western  emperor. In 410 Alaric occupied and plundered Rome, the first time the  city had been captured by a foreign enemy in 800 years.

It is the largest in area of the U.S. states,  covering 587,875 sq mi (1,522,595 sq km). Bordered by Canada to the  east and southeast and facing Siberia across the Bering Strait and Bering  Sea to the west, it has the highest point on the continent, Mount McKin�  ley. Its capital is Juneau. The original inhabitants, Indians and Eskimos,  are thought to have migrated over the Bering Land Bridge as well as from  the Arctic. The first European settlement was established in the late 18th  century by Russian fur traders on Kodiak Island. Hudson's Bay Co. traders  were also interested in the same area, and Russian-Canadian trade rivalry  lasted well into the 19th century. In 1867 William Seward negotiated Alas�  ka�s sale from the Russians to the U.S., and the subsequent discovery of  gold stimulated American settlement. Alaska was a U.S. territory from  1912 until it was admitted as the 49th state in 1959. Its economy has  become increasingly centred on oil and natural gas: since the opening of  the Trans-Alaska Pipeline in 1977, Alaska has become second only to Texas  in the U.S. production of crude oil.</p><p>Alaska, Gulf of Broad inlet, southern Alaska, U.S. Situated between  the Alaska Peninsula and the Alexander Archipelago, it receives the Susitna  and Copper rivers.

The territory, held  by Russia since 1741, was considered an economic liability, and in 1866  it was offered for sale. Pres. Andrew Johnson�s secretary of state, William  Seward, negotiated its purchase for $7.2 million, or about two cents per  acre. Critics labeled the purchase �Seward�s Folly.� Congressional oppo�  sition delayed the appropriation until 1868, when extensive lobbying and  bribes by the Russian minister to the U.S. secured the required votes.</p><p>Alaska Range Mountain range, southern Alaska, U.S. A segment of  the Pacific mountain system, it extends in an arc from the Aleutian Range  on the Alaska Peninsula to the Yukon Territory boundary.

In the face of  the fragmentation of the Toungoo dynasty, Alaungpaya (1714-60), head�  man in a village near Mandalay, raised an army and subdued the sepa�  ratist Mon people in southern Myanmar and then conquered the  northeastern Shan states. He attacked the Siamese capital of Ayutthaya  (now in Thailand) but was forced to retreat. His son Hsinbyushin, the third  king of the dynasty (r. 1763-76), sent armies into neighbouring kingdoms  and successfully rebuffed four retaliatory Chinese invasions. The sixth  king, Bodawpaya (r. 1782-1819), mounted a number of unsuccessful cam�  paigns against the Siamese and moved the capital to Amarapura. He also  conquered the kingdom of Arakan. His incursions into Assam aroused the  ire of the British, and under Bagyidaw (r. 1819-37) Myanmar (subse�  quently Burma) was defeated in the first Anglo-Burmese War.

Albania has a developing free-market economy that until  1991 was shaped by a socialist system of state ownership. The Albanians  are descended from the Illyrians, an ancient Indo-European people who  lived in central Europe and migrated south by the beginning of the Iron  Age (see Illyria). The Gegs settled in the north and the Tosks in the south,  along with Greek colonizers. The area was under Roman rule by the 1st  century bc; after ad 395 it was connected administratively to Constanti�  nople.

After the war a socialist govern�  ment under Enver Hoxha was installed, and gradually Albania cut itself off  from the nonsocialist international community and eventually from all  other countries, including China, its last political ally. By 1990 economic  hardship had fomented antigovernment demonstrations that led to the  election of a noncommunist government in 1992 and the end of Albania�s  international isolation.

Albanian is the  only extant representative of a distinct branch of Indo-European, whose  pre-Roman Balkan ancestry is uncertain. The earliest written attestation  is from the 15th century, though a standard orthography using the Latin  alphabet was not adopted until 1909.

Albatrosses come ashore only to breed, in colo�  nies typically established on remote oceanic islands. Adults of common  species attain wingspans of 7-11 ft (200-350 cm). Albatrosses live long  and may be among the few birds to die of old age. They were once held  in awe by seamen, who held that killing one would bring bad luck.</p><p>albedo \al-'be-do\ Fraction of light reflected by a body or surface, com�  monly used in astronomy to describe the reflective properties of planets,  natural satellites, and asteroids. �Normal� albedo (the relative brightness  of a surface when illuminated and observed from directly above) is often  used to determine the surface compositions of satellites and asteroids.

He was the adopted grandson and namesake of a  well-known vaudeville theatre manager. His first one-act play, The Zoo  Story (1959), and other early plays, including The Sandbox (I960) and  The American Dream (1961), were characteristic of the Theatre of the  Absurd. His Who�s Afraid of Virginia Woolf (1962; film, 1966) was widely</p><p>acclaimed. He won Pulitzer prizes for A Delicate Balance (1966), Sea�  scape (1975), and Three Tall Women (1991).

A piano prodigy by age four, he later studied in Leipzig and  Brussels, returned to Spain to teach in Barcelona and Madrid, and then  moved to France in 1893. His fame rests on his piano pieces, which, under  the influence of Felipe Pedrell, utilize the melodic styles, rhythms, and har�  monies of Spanish folk music. Iberia (1905-09) is a set of 12 virtuoso  piano pieces; other piano works include the Suite espahola (1886), Can�  tos de Espaha (1896), and five sonatas. He also wrote several operas.</p><p>Albers, Josef (b. March 19, 1888, Bottrop, Ger.�d. March 25, 1976,  New Haven, Conn., U.S.) German-  U.S. painter, poet, teacher, and theo�  retician. He studied and taught at the  Bauhaus and in 1933 became one of  the first Bauhaus teachers to immi�  grate to the U.S., where he taught at  Black Mountain College and later at  Yale. He developed a painting style  characterized by abstract rectilinear  patterns and primary colours as well  as black and white. His best-known  series of paintings, Homage to the  Square (begun in 1950 and contin�  ued until his death), restricts its rep�  ertory of forms to coloured squares  superimposed onto each other. The  arrangement of these squares is care�  fully calculated so that the colour of  each square optically alters the sizes,  hues, and spatial relationships of the  others. His research into colour  theory was published in the influential Interaction of Color (1963).</p><p>Albert, prince consort of Great Britain and Ireland orig.

Prince consort of Queen Victoria of Britain and father of Edward VII.  Albert married Victoria, his first cousin, in 1840 and became in effect her  private secretary and chief confidential adviser. Their domestic happiness  helped assure the continuation of the monarchy, which had been some�  what uncertain. Though the German-born Albert was undeservedly  unpopular, the British public belatedly recognized his worth after his death  at age 42 from typhoid fever. In the ensuing years the grief-stricken queen  made policy decisions based on what she thought Albert would have done.</p><p>Albert, Lake Lake, east-central Africa.

With an area of 255,287 sq mi (661,190 sq km), Alberta  is bordered by Saskatchewan, British Columbia, the Northwest Territo�  ries, and the U.S. Its capital is Edmonton. Long inhabited by various  Indian peoples, the area was explored by Europeans in the 1750s. It even�  tually came under the rule of the Hudson's Bay Co., which transferred it  to the Dominion of Canada in 1870. It was made part of the Northwest  Territories in 1882. Its population grew with the coming of the railroads  and the expansion of wheat farming. Alberta was made a province in 1905.  Once dependent on agriculture, it underwent economic growth with the  discovery of oil in 1947 and the ensuing discovery of other major oil and  gas deposits.</p><p>Alberta, University of Canadian public university in Edmonton.

Feb. 14, 1404, Genoa�d. April 25, 1472,  Rome) Italian architect, art theorist, and humanist. After pursuing a lit�  erary career as papal secretary, in 1438 Alberti was encouraged to direct  his talents toward the field of architecture. His designs for the Palazzo  Rucellai (c. 1445-51) and the facade of Santa Maria Novella (1456-70),  both in Florence, are noted for their harmonic proportions. His central-  plan church of Sant�Andrea, Mantua (begun 1472), with its triumphal-  arch motif, is an early Renaissance masterpiece. Alberti was one of the  foremost theorists on Renaissance architecture and art, known for codi�  fying the principles of linear perspective (in On Painting, 1436). A pro�  totype of the Renaissance man, he also made contributions to moral  philosophy, cartography, and cryptography.</p><p>Albertus Magnus, Saint (b. c. 1200, Lauingen on the Danube, near  Ulm, Bavaria�d.

At the Uni�  versity of Paris he was introduced to  the works of Aristotle and to Aver-  roes� commentaries and decided to  present to his contemporaries the  entire body of human knowledge as  seen by Aristotle and his commenta�  tors. For 20 years he worked on his  Physica, which encompassed natural  science, logic, rhetoric, mathematics,  astronomy, ethics, economics, poli�  tics, and metaphysics. He believed  that many points of Christian doc�  trine were recognizable both by faith  and by reason. In 1248 he organized  the first Dominican studium generale (�general house of studies,� a pre�  cursor to the university) in Germany, at Cologne. Thomas Aquinas, who  had been with Albertus in Paris and joined him in Cologne, was his chief  disciple at this time. His works represented the entire body of European  knowledge of his time, and he contributed greatly to the development of  natural science.</p><p>Albigensian X.al-bo-'jen-shonV Crusade (1209-29) Crusade called by  Pope Innocent III against the heretical Cathari of southern France. The war  pitted the nobility of northern France against that of southern France, and  it eventually involved the king of France who established his authority  over the south. The Crusade ended with the Treaty of Paris (1229), which  took away the independence of the southern princes and largely destroyed  the culture of Provence. The Crusade caused much devastation and injus�  tice, which Innocent came to regret, but did not bring about the extirpa�  tion of the Albigensian heresy (named for its center in the town of Albi,  France). The heresy lingered on into the 13th�14th centuries and became  the object of the Inquisition.</p><p>Albigensians See Cathari</p><p>albinism Val-bo-.ni-zom, al-'bl-.ni-zoirA Absence of the pigment mela�  nin in the eyes, skin, hair, scales, or feathers. It arises from a genetic defect  and occurs in humans and other vertebrates. Because they lack the pig�  ments that normally provide protective coloration and screen against the  sun�s ultraviolet rays, albino animals rarely survive in the wild. Humans  have long intentionally bred certain albino animals (e.g., rabbits) for their  appearance. In humans with generalized, or total, albinism, the affected  person has milk-white skin and hair; the iris of the eye appears pink, the  pupil red. Vision abnormalities such as astigmatism, nystagmus (rapid  involuntary oscillation of the eye), and photophobia (extreme sensitivity  to light) are common. Generalized albinism occurs throughout the world  in about one in 20,000 persons.</p><p>Albinoni \,al-b3-'no-ne\, Tomaso (Giovanni) (b. June 8/14, 1671,  Venice�d.

He had more than 50 operas successfully pro�  duced between 1694 and 1741, though few survive. His approximately 60  concertos became popular; he also wrote more than 80 sonatas for vari�  ous instrumental combinations and many solo cantatas.

Independently wealthy, he studied at various institutions, devel�  oping a meticulously detailed style and often spending several years of  painstaking work on a single painting. With pinpoint exactness and hal�  lucinatory hyperclarity, he repeatedly depicted decay, corruption, and the  wreckage of age, often with great emotional intensity. Among his impor�  tant works is That Which I Should Have Done I Did Not Do (1931-41).

Ancient alchemists believed that, under the correct astrological  conditions, lead could be �perfected� into gold. They tried to hasten this  transformation by heating and refining the metal in a variety of chemical  processes, most of which were kept secret. Alchemy was practiced in  much of the ancient world, from China and India to Greece. It migrated  to Egypt during the Hellenistic period and was later revived in 12th-  century Europe through translations of Arabic texts into Latin. Medieval  European alchemists made some useful discoveries, including mineral  acids and alcohol. The revival led to the development of pharmacology  under the influence of Paracelsus and to the rise of modem chemistry. Not  until the 19th century were the gold-making processes of alchemists  finally discredited.</p><p>Alcibiades N.al-so-'bl-o-.dezV (b. c. 450 bc, Athens�d. 404, Phrygia)  Athenian politician and commander. Pericles was his guardian, his father  having died in battle. Alcibiades grew up without much guidance, but as  a youth he was drawn to Socrates� moral strength and keen mind.  Socrates, in turn, was attracted to the youth�s physical beauty and intel�  lectual promise. They served together in the Peloponnesian War, saving  each other�s life in battle, yet eventually Alcibiades was led by his own  unscrupulous ambition. By 420 he was a general. Recalled from a Sicil�  ian expedition in 415 on charges of sacrilege, he fled to Sparta. Though  he aided the Spartan cause against Athens, he was eventually rejected and  sought haven with the Persian governor at Sardis. The Athenian fleet  eventually recalled him, and he directed Athenian victories 411-408.  Though he achieved hero status, his enemies forced him to leave. From  Thrace he warned Athens presciently of danger at the Battle of Aegospot-  ami. He fled from Thrace to Phrygia, where the Spartans conspired to have  him murdered. His political agitation was a decisive factor in the defeat  of Athens in the Peloponnesian War. His notorious behaviour helped  strengthen the charges brought against Socrates in 399.</p><p>Alcmaeon or Alcmeon \alk-'me-3n\ In Greek mythology, the son of  the seer Amphiaraus.

Alc�  maeon led the sons of the seven in the destruction of Thebes and then  obeyed his father�s injunction to kill his mother, a crime for which the  Furies drove him mad. He was purified by King Phegeus of Psophis, whose  daughter he married but subsequently killed. Following the advice of an  oracle, he settled on an island at the mouth of the Achelous River, where  he married again, but was killed by Phegeus and his sons.</p><p>Alcmaeonid family \alk-'me-9n-id\ Athenian family important in the  6th-5th century bc. During the archonship (magistracy) of the Alcmae�  onid Megacles (632? bc), the family was banished for murder; it returned  twice to oust the tyrant Peisistratus before again being exiled. Megacles�  son Cleisthenes became archon in 525/524, but in 514 Peisistratus� son  Hippias again exiled the family for murdering his brother. The family  reestablished itself after the Spartans drove out the Peisistratids in 510.  The next generation may have aided the Persians at the Battle of Mara�  thon (490).

Many alcohols occur natu�  rally and are valuable intermediates in the synthesis of other compounds  because of the characteristic chemical reactions of the hydroxyl group.  Oxidation (see oxidation-reduction) of primary alcohols yields aldehydes  and (if taken further) carboxylic acids; oxidation of secondary alcohols,  ketones. Tertiary alcohols break down on oxidation. Alcohols generally  react with carboxylic acids to produce esters. They may also be converted  to ethers and olefins. Products of these numerous reactions include fats  and waxes, detergents, plasticizers, emulsifiers, lubricants, emollients, and  foaming agents. Ethanol (grain alcohol) and methanol (wood alcohol) are  the best-known alcohols with one hydroxyl group. Glycols (e.g., ethylene  glycol, or antifreeze) contain two hydroxyl groups, glycerol three, and  polyols three or more. See also alcoholic beverage, alcoholism.</p><p>alcoholic beverage Any fermented liquor, such as wine, beer, or dis�  tilled liquor, that contains ethyl alcohol, or ethanol, as an intoxicating  agent. When an alcoholic beverage is ingested, the alcohol is rapidly  absorbed in the stomach and intestines because it does not undergo any  digestive processes. It is distributed to the rest of the body through the  blood and has a pronounced depressant action on the brain. Under the  influence of alcohol, the drinker is less alert, less able to discern objects  in the environment, slower in reacting to stimuli, and generally prone to  sleep.</p><p>Alcoholics Anonymous (AA) Voluntary fellowship of people suf�  fering from alcoholism who seek to become and stay sober through mutual  self-help by meeting in local, independent groups to share their common  experience. Anonymity, confidentiality, and understanding of alcoholism  as a disease free members to speak frankly. Many consider AA to be the  most successful method of coping with alcoholism; participation raises  the chances of success of other treatments. Its 12 steps to recovery include  acknowledgment of the problem, faith in a �higher power� as understood  by each individual, self-examination, and a desire to change for the bet�  ter and to help others recover. Begun in 1935 by two alcoholics, AA has  grown to some 2 million members worldwide. Similar organizations for  abusers of other substances and for habitual gamblers and debtors are  based on its principles.</p><p>alcoholism Excessive habitual consumption of alcoholic beverages  despite physical, mental, social, or economic harm (e.g., cirrhosis, drunk  driving and accidents, family strife, frequently missing work). Persons  who drink large amounts of alcohol over time become tolerant to its  effects. Alcoholism is usually considered an addiction and a disease. The  causes are unclear, but there may be a genetic predisposition. It is more  common in men, but women are more likely to hide it. Treatment may  be physiological (with drugs that cause vomiting and a feeling of panic  when alcohol is consumed; not an effective long-term treatment), psycho�  logical (with therapy and rehabilitation), or social (with group therapies).  Group therapies such as Alcoholics Anonymous are the most effective  treatments. Suddenly stopping heavy drinking can lead to withdrawal  symptoms, including delirium tremens.</p><p>Alcott, (Amos) Bronson (b. Nov. 29, 1799, Wolcott, Conn., U.S.�d.  March 4, 1888, Concord, Mass.)

He traveled to Britain with money borrowed from Ralph Waldo  Emerson and came back with the mystic Charles Lane, with whom he  founded the short-lived utopian community Fruitlands outside Boston.  Alcott is credited with establishing the first parent-teacher association in  Concord, Mass., while he was superintendent of schools there. A promi�  nent member of the Transcendentalists, he wrote a number of books but  did not become financially secure until his daughter Louisa May Alcott  achieved success.</p><p>Alcott, Louisa May (b.

She began writing to help support her mother and sisters.  An ardent abolitionist, she volunteered as a nurse during the American  Civil War, where she contracted the typhoid that damaged her health the  rest of her life; her letters, published as Hospital Sketches (1863), first  brought her fame. With the huge success of the autobiographical Little  Women (1868-69), she finally escaped debt.

He also  made important reforms in the  Roman Catholic liturgy, prepared an  important new edition of the Vulgate  Bible, wrote a number of poems, and  left more than 300 Latin letters, a  valuable source for the history of his  time. Although traditionally identi�  fied as the author of the Caroline  books and as the creator of Carolin�  gian miniscule, Alcuin is now recog�  nized as having played a less  important role in the creation of  both.

Many have characteristic odours.  Oxidation (see oxidation-reduction) of aldehydes yields acids; reduction  produces alcohols. They participate in many chemical reactions and readily  undergo polymerization into chains containing tens of thousands of the  monomer molecule. The combination of aldehydes (e.g., formaldehyde)  with other molecules results in several familiar plastics. Many aldehydes  are large-scale industrial materials, useful as solvents, monomers, per�  fume ingredients, and intermediates. Many sugars are aldehydes, as are  several natural and synthetic hormones and compounds such as retinal (a  derivative of vitamin A, important in vision) and pyridoxal phosphate (a  form of vitamin B 6 ).</p><p>Alden, John (b. 1599?, England�d.

Alders  are distinguished from birches by  their usually stalked winter buds and  by cones that remain on the branches  after the small, winged nutlets are  released. Alders have scaly bark,  oval leaves that fall without chang�  ing colour, and separate male and  female flowers (catkins) borne on the  same tree. Some familiar North  American alders are the red alder (A.  rubra or A. oregonaf, the white, or  Sierra, alder (A. rhombifoliaf and the speckled alder (A. rugosa). Alder  wood is fine-textured and durable, even under water; it is useful for fur�  niture, cabinetry, and lathe work and in charcoal manufacture and mill-  work. Alders� spreading root systems and tolerance of moist soils lend  them to planting on stream banks for flood and erosion control.</p><p>Aldrich, Nelson W(ilmarth) (b.

In alea�  tory music aspects such as the ordering of a piece�s sections, its rhythms,  and even its pitches are decided at the moment of performance. When not  purely improvising, players follow lists of arbitrary rules or interpreted  �graphic� notation that merely suggest the sounds.

Lying at the crossroads of great commer�  cial routes, it has long been inhabited and is first mentioned at the end of  the 3rd millennium bc. It subsequently came under the control of many  kingdoms, including the Hittites (17th�14th centuries bc). Controlled by  the Persian Achaemenian dynasty in the 6th-4th centuries bc, it soon came  under the control of the Hellenistic Seleucid dynasty, under which it was  renamed Beroea. It was absorbed into the Roman Empire in the 1st cen�  tury bc and it prospered for several centuries. In ad 637 it was conquered  by the Arabs, under whom it reverted to its old name, Halab. The city  successfully defended itself from the Crusaders (1124), fell to the Mon�  gols (1260), and finally was incorporated into the Ottoman Empire (1516).

He was the son of an Italian immigrant, and his election  in 1920 represented the urban classes� first successful challenge to Chile�s  oligarchy. When he defended workers� groups and attempted liberal  reforms, he encountered stiff opposition in Congress. A coup led by Car�  los IbAnez forced him into exile, but he was soon recalled and drafted a  new constitution that increased the president�s power. He became presi�  dent again in 1932 during the Great Depression, dependent for support on  the political right.

The name Aleut, used in 1745 by Russian fur  traders from the Kamchatka Peninsula, refers primarily to the people of  the Aleutian Islands, who call themselves Unangan or Unangas, but also  by extension to the Pacific Yupik, who call themselves Alutiit (plural of  Alutiiq), an adaptation of the Russian name. Aleuts speak two main dia�  lects and are physically and culturally closely related to the Eskimo. Tra�  ditional Aleut villages were located on the seashore near fresh water,  where the people hunted marine mammals, fish, birds, caribou, and bear.  Aleut women wove fine grass basketry; stone, bone, and ivory were also  worked. After the arrival of the Russians in the 18th century, their popu�  lation declined drastically.

The  major island groups, from east to west, are the Fox Islands (including  Unimak and Unalaska), Islands of the Four Mountains, Andreanof Islands  (including Adak), and Near Islands (including Attu). The main settlements  are on Unalaska and Adak. Originally inhabited by Aleuts, the islands  were explored by Russian-sponsored ships in 1741. As Siberian fur hunt�  ers moved eastward through the islands, the Russians gained a foothold  in North America but nearly caused the extinction of the Aleuts.

In 1940 he helped  direct the Dunkirk evacuation and was the last man to leave the beaches.  Appointed British commander in chief in the Mediterranean theatre in  1942, he helped lead the North Africa Campaign against the Germans. He  directed the invasions of Sicily and Italy, then became commander in chief  of Allied forces in Italy. After the war, he served as governor-general of  Canada (1946-52) and as Britain�s minister of defense (1952-54).</p><p>Alexander, Severus See Severus Alexander</p><p>Alexander, William See William Alexander, 1st earl of Stirling</p><p>Alexander I Russian Aleksandr Pavlovich (b.

He and his advisers corrected many of the injustices of the preceding reign  but failed to carry out the abolition of serfdom. During the Napoleonic  Wars he alternately fought and befriended Napoleon and helped form the  coalition that finally defeated him. Alexander also participated in the Con�  gress of Vienna (1814-15) and formed the Holy Alliance (1815). After his  sudden death in 1825, a legend sprang up that he had simply �departed�  to a Siberian retreat.</p><p>Alexander I (b. Dec. 4, 1888, Cetinje, Montenegro �d.

After commanding Ser�  bian forces in World War I, Alexander succeeded his father, Peter I, as  king of the Kingdom of Serbs, Croats, and Slovenes in 1921. In 1929 he  abolished the constitution and established a royal dictatorship. As part of  his efforts to unify his subjects, he changed the name of the country to  Yugoslavia; outlawed political parties based on ethnic, religious, or  regional distinctions; reorganized the state; and standardized legal sys�  tems, school curricula, and national holidays. In 1934 he was assassinated  by an agent of Croatian separatists.</p><p>Alexander II Russian Aleksandr Nikolayevich (b. April 29,  1818, Moscow, Russia�d. March 13, 1881, St. Petersburg) Tsar of Rus�  sia (1855-81). He succeeded to the throne at the height of the Crimean  War, which revealed Russia�s backwardness on the world stage. In  response, he undertook drastic reform, improving communications, gov�  ernment, and education, and most importantly, emancipating the serfs  (1861). His reforms reduced class privilege and fostered humanitarian  progress and economic development. Though sometimes described as a  liberal, Alexander was in reality a firm upholder of autocratic principles,  and an assassination attempt in 1866 strengthened his commitment to  conservatism. A period of repression after 1866 led to a resurgence of  revolutionary terrorism, and in 1881 he was killed in a plot sponsored by  the terrorist organization People�s Will.</p><p>Alexander II (b. Aug. 24, 1198, Haddington, Lothian�d. July 8, 1249,  Kerrera Island) King of Scotland (1214�49). He came to the throne on  the death of his father, William I (the Lion). In 1215 he supported the  rebellious English barons against King John, hoping to regain land in  northern England. After the rebellion collapsed (1217), he did homage to  Henry III and in 1221 married Henry�s sister, Joan. He consolidated royal  authority in Scotland and subdued Argyll in 1222. In 1237 he concluded  the Peace of York with Henry by which he abandoned his claim to land  in England and received in exchange several English estates.</p><p>Alexander III See Alexander the Great</p><p>Alexander III orig. Rolando Bandinelli (b. c. 1105, Siena,  Tuscany�d. Aug. 30, 1181, Rome) Pope (1159-81). A member of the  group of cardinals who feared the growing strength of the Holy Roman  Empire, he helped draw up an alliance with the Normans (1156). As the rep�  resentative of Pope Adrian IV, he angered Frederick I (Frederick Bar-  barossa) by referring to the empire as a �benefice,� implying that it was a  gift of the pope. On Alexander�s election as pope in 1159, a minority of  cardinals supported by Frederick elected the first of several antipopes, and  imperial opposition obliged Alexander to flee to France (1162). A vigorous  defender of papal authority, he supported St. Thomas Becket against Henry  II of England. He returned to Rome in 1165 but was exiled again the fol�  lowing year. He gained support with the formation of the Lombard League,  which defeated Frederick at Legnano in 1176, paving the way for the  Peace of Venice and the end of the papal schism. Alexander stood in the  reform tradition and presided at the third Lateran Council (1179).</p><p>Alexander III Russian Aleksandr Aleksandrovich (b. March  10, 1845, St. Petersburg, Russia�d. Nov. 1, 1894, Livadiya, Crimea) Tsar  of Russia (1881-94). He assumed the throne after the assassination of his  father, Alexander II. The internal reforms he instituted were designed to  correct what he saw as the too-liberal tendencies of his father�s reign. He  thus opposed representative government and ardently supported Russian  nationalism. His political ideal was a nation containing a single nation�  ality, language, religion, and form of administration, and accordingly he  instituted programs such as the Russification of national minorities in the  Russian Empire and the persecution of non-Orthodox religious groups.</p><p>Alexander III (b. Sept. 2, 1241�d. March 18/19, 1286, near Kinghorn,  Fife, Scot.) King of Scotland (1249-86). Son of Alexander II, he came to the  throne at age 7. In 1251 he was married to Margaret, daughter of England�s  King Henry III, who sought to gain control over Scotland. In 1255 Alex�  ander was seized by a pro-English party in Scotland; in 1257 the anti-  English party gained control of the government until he came of age  (1262). In 1263 he repulsed a Norwegian invasion, and in 1266 he acquired  the Hebrides and the Isle of Man from Norway. His reign was later viewed  as a golden age by Scots caught up in the long conflict with England.</p><p>Alexander VI orig. Rodrigo de Borja y Dorns (b. 1431, Jativa,  Aragon�d.

Bom into the  Spanish branch of the Borgia family,  he amassed great wealth and lived  scandalously, fathering four illegiti�  mate children (before his election as  pope), who played an important role  in his complicated dynastic plans. He  warred against the Ottoman Turks  and forced the French to abandon  their effort to seize Naples. The mur�  der of his son Juan (1497) prompted  Alexander�s short-lived attempt to  restrain the corruption of the papal  court. His political ambitions, how�  ever, were revived with the marriage  of his son Cesare, whose military  campaigns brought northern Italy  under Borgia control. He concluded  an alliance with Spain and negotiated the Treaty of Tordesillas (1494). A  patron of the arts, he embellished the Vatican palaces and commissioned  Michelangelo to draw up plans for the rebuilding of St. Peter's Basilica.</p><p>Alexander Archipelago Group of about 1,100 islands, southeastern  Alaska, U.S. Extending southward from Glacier Bay, the chief islands are  Chichagof, Admiralty, Baranof, Kupreanof, Prince of Wales, and Revil-  lagigedo.

He fought off invading Swedes in 1240 at the Neva River  (resulting in the epithet Nevsky). He was called back to service to defeat  the Teutonic Knights in 1242 and also won victories over the Lithuanians  and Finns. He collaborated with the Golden Horde in imposing Mongol  rule on Russia, and the Great Khan made him grand prince of Vladimir.  Alexander continued to rule Novgorod through his son. He helped the  Mongols impose taxes, interceding with the Khan to prevent reprisals  when rebellions broke out. A national hero, he was canonized by the Rus�  sian Orthodox church.</p><p>Alexander the Great or Alexander III (b. 356 bc, Pella,  Macedonia�d. June 13, 323 bc, Babylon) King of Macedonia (336-323)  and the greatest military leader of antiquity. The son of Philip II of Mace�  donia, he was taught by Aristotle. He soon showed military brilliance,  helping win the Battle of Chaeronea at age 18. He succeeded his assas�  sinated father in 336 and promptly took Thessaly and Thrace; he brutally  razed Thebes except for its temples and the house of Pindar. Such destruc�  tion was to be his standard method, and other Greek states submitted  meekly. In 334 he crossed to Persia and defeated a Persian army at the  Granicus River. He is said to have cut the Gordian knot in Phrygia (333),  by which act, according to legend, he was destined to rule all Asia. At the  Battle of Issus in 333, he defeated another army, this one led by the Per�  sian king Darius III, who managed to escape. He then took Syria and  Phoenicia, cutting off the Persian fleet from its ports. In 332 he completed  a seven-month siege of Tyre, considered his greatest military achievement,  and then took Egypt. There he received the pharaohs� double crown,  founded Alexandria, and visited the oracle of the god Amon, the basis of  his claim to divinity. In control of the eastern Mediterranean coast, in 331  he defeated Darius in a decisive battle at Gaugamela, though Darius again  escaped. He next took the province of Babylon. He burnt Xerxes' palace  at Persepolis, Persia, in 330, and he envisioned an empire ruled jointly by  Macedonians and Persians. He continued eastward, quashing real or imag�  ined conspiracies among his men and taking control to the Oxus and Jax-  artes rivers, founding cities (most named Alexandria) to hold the territory.  Conquering what is now Tajikistan, he married the princess Roxana and  embraced Persian absolutism, adopting Persian dress and enforcing Per�  sian court customs. By 326 he reached the Hyphasis in India, where his  weary men mutinied; he turned back, marching and pillaging down the  Indus, and reached Susa with much loss of life. He continued to promote  his unpopular policy of racial fusion, a seeming attempt to form a Persian-  Macedonian master race. When his favourite, Hephaestion (324), died,  Alexander gave him a hero�s funeral and demanded that divine honours  be given at his own funeral. He fell ill at Babylon after long feasting and  drinking and died at age 33. He was buried in Alexandria, Egypt. His  empire, the greatest that had existed to that time, extended from Thrace  to Egypt and from Greece to the Indus valley.</p><p>Alexanderson, Ernst F(rederik) W(erner) (b.

He emigrated to the  U.S. in 1901 and spent most of the next five decades at General Electric;  from 1952 he worked for RCA. He developed a high-frequency alterna�  tor that was capable of producing continuous radio waves, revolutioniz�  ing radio communication. His completed alternator (1906) greatly  improved transoceanic communication and firmly established the use of  wireless devices in shipping and warfare. He also developed a sophisti�  cated control system (1916) used to automate intricate manufacturing  processes and operate antiaircraft guns.

A granddaughter of Queen Victoria, she married Nicho�  las in 1894 and sought to restore absolute power in the monarchy. Des�  perate to help her hemophiliac son, Alexis, she turned to the hypnotic  powers of Grigory Rasputin, who became her spiritual adviser. In 1915  Nicholas left Moscow to command Russian forces in World War I, and  Alexandra dismissed capable ministers and replaced them with nonenti�</p><p>ties favored by Rasputin. Her misrule contributed to the collapse of the  imperial government. After the Bolshevik takeover in the Russian Revo�  lution of 1917, the royal family was imprisoned and later executed.</p><p>Alexandria Arabic Al-lskandarlyah City (metro, area pop., 2004  est.: 3,755,900) and chief seaport, northern Egypt.

It was part  of Washington, D.C., from 1801 to 1847, after which it was ceded back  to Virginia. Many colonial buildings survive in Alexandria�s Old Town;  George Washington�s estate, Mount Vernon, is nearby.</p><p>Alexandria, Library of Most famous library of classical antiquity.  It was part of the Alexandrian Museum, a research institute at Alexandria,  Egypt. The museum and library were founded and maintained by a suc�  cession of Ptolemies from the early 3rd century bc. The library aspired  to the ideal of an international library�incorporating all Greek literature  and also translations into Greek�but it is uncertain how close this ideal  came to being realized. A bibliography of the library compiled by Calli�  machus, lost in the Byzantine period, was long a standard reference work.  The museum and library were destroyed in civil war in the late 3rd cen�  tury ad; a subsidiary library was destroyed by Christians in ad 391.</p><p>Alexandria, Museum of Ancient centre of Classical learning at  Alexandria, Egypt. It was a research institute, organized into faculties and  headed by a president-priest, with a renowned library. It was built near  the royal palace either by Ptolemy II Philadelphus c. 280 bc or by his father,  Ptolemy I Soter. The best surviving description is by Strabo. In ad 270 its  buildings were destroyed, although its educational and research functions  seem to have continued until the 5 th century.</p><p>Alexandrina X.a-lig-.zan-'dre-noV Lake Lagoon, southeastern South  Australia. The lake covers 220 sq mi (570 sq km) and is about 23 mi (37  km) long and 13 mi (21 km) wide. With Lake Albert and the Coorong  lagoon, it forms the mouth of the Murray River. In 1830 the explorer  Charles Sturt named the lake after Princess Alexandrina (later Queen Vic�  toria). Five barrages built in the 1940s across the lake�s exits prevent the  intrusion of seawater upstream, allowing for the development of irrigated  agriculture in that area.</p><p>alexandrine X.al-ek-'zan-dronX Verse form that is the most popular  measure in French poetry. It consists of a line of 12 syllables with a pause  after the sixth syllable, major stresses on the sixth and the last syllable,  and one secondary accent in each half line. It is a flexible form, adapt�  able to a wide range of subjects. It became the preeminent French verse  form for dramatic and narrative poetry in the 17th century and reached  its highest development in the tragedies of Pierre Corneille and Jean Racine.</p><p>Alexandrists Italian Renaissance philosophers, led by Pietro Pompon-  azzi (1462-1525), who followed the explanation of Aristotle�s De anima  given by Alexander of Aphrodisias (2nd-3rd century ad). Alexander held  that De anima denied individual immortality, considering the soul a mate�  rial and therefore a mortal entity, organically connected with the body.  The Alexandrists disagreed with Thomas Aquinas and his followers, who  interpreted Aristotle as saying that the individual soul is immortal, and  with the Latin Averroists (see Averroes), who held that the individual  intellect is reabsorbed after death into the eternal intellect.</p><p>Alexis Russian Aleksey Mikhaylovich (b.

He  protected the Eastern Orthodox  church but did not hesitate to seize its  assets when in financial need. His  appeal for Western support in 1095  was a factor in Pope Urban II�s call for  the First Crusade. Alexius�s relations  with the Crusaders were difficult, and  from 1097 onward the Crusades frus�  trated his foreign policy.</p><p>Alexius V Ducas Mourt-  zouphlus \thu-kas-'murt-su-fl6s\</p><p>(d. 1204, Constantinople) Byzantine  emperor.

It is widely  grown primarily for hay, pasturage, and silage. It is known for its toler�  ance of drought, heat, and cold, and for its improvement of soil by nitri�  fication (see nitrifying bacteria) due to bacteria associated with its roots.  The plant, which grows 1-3 ft (30-90 cm) tall, develops numerous stems  that arise from a much-branched crown at soil level, each bearing many  three-leaved leaflets. Its long primary root �as long as 50 ft (15 m) in  some plants�accounts for its unusual ability to tolerate drought. Its  remarkable capacity for regeneration of dense growths of new stems and  leaves following cutting makes possible as many as 13 crops of hay in  one growing season. Alfalfa hay is very nutritious and palatable, high in  protein, minerals, and vitamins.</p><p>Alfasi \al-'fa-se\, Isaac ben Jacob (b. 1013, near Fes, Mor.�d. 1103,  Lucena, Spain) Moroccan Jewish scholar. He spent most of his life in Fes,  but in 1088 he was denounced to the government and was obliged to flee  to Spain. He became head of the Jewish community in Lucena and estab�  lished a noted Talmudic academy, provoking a rebirth of Talmudic study  in Spain. His codification of the Talmud, Sefer ha-Halakhot (�Book of  Laws�), deals with Halakhah (Hebrew law) and ranks with the works of  Maimonides and Karo. It was crucial in establishing the primacy of the  Babylonian Talmud over the Palestinian Talmud.</p><p>Alferov, Zhores (Ivanovich) (b. March 15, 1930, Vitebsk, Belorus-  sia, U.S.S.R.)

Jan. 16, 1749, Asti,  Piedmont�d. Oct. 8, 1803, Florence) Italian tragic poet and playwright.  Through his lyrics and dramas he helped revive the national spirit of Italy.  After a period of travel in which he experienced English political liberty  and read the works of Montesquieu and other French writers, he left the  military and began writing. His tragedies almost always present the  struggle between a champion of liberty and a tyrant. Of the 19 tragedies  that he approved for publication in an edition of 1787-89, the best are  Filippo, Antigone, Oreste, Mirra, and his masterpiece, Saul, often con�  sidered the most powerful drama in the Italian theatre. His autobiography  (1804) is his chief prose work.</p><p>Alfonsm \al-fon-'sen\ (Foulkes), Raul (Ricardo) (b. March 13,  1926/7, Chascomus, Buenos Aires, Arg.)

After Argentina lost the Falkland Islands War,  the discredited military permitted free elections, and Alfonsm defeated  the Peronist candidate. He prosecuted members of the armed forces for  human rights violations, but military pressure (including several armed  revolts) led him to pardon most convicted officers. His presidency was  plagued by high inflation, a huge national debt, labour disputes, and a  discontented military.

Taken pris�  oner by the Genoese (1435) while preparing to attack Naples, he per�  suaded his captors into an alliance and conquered Naples (1442), to which  he transferred his court. He engaged in much diplomatic and military  activity in Africa, the Balkans, and the eastern Mediterranean in order to  protect his commerce with the East and defend Christendom against the  Turks. He died during an assault on Genoa.</p><p>Alfonso VI known as Alfonso the Brave (b. before June 1040�d.  1109, Toledo, Castile) King of Leon (1065-70) and of Castile and Leon  (1072-1109). He inherited Leon from his father, Ferdinand I, and warred  with his envious brother Sancho II. On Sancho�s death he inherited Castile  (1072); he also occupied Galicia and imprisoned his brother Garcia, its  rightful ruler. In 1077 Alfonso proclaimed himself emperor of all Spain.  He took Toledo from the Muslims, but his demands for tribute led to the  invasion of Spain by the North African Almoravids, and he was defeated  at Zallaqah (1086). The ClD became an ally and defended eastern Spain,  but Alfonso continued to lose ground against the Berber armies.</p><p>Alfonso X known as Alfonso the Wise (b. Nov. 23, 1221, Burgos,  Castile�d.

He crushed revolts by Muslims (1252) and nobles (1254), and he annexed  Murcia after repelling an invasion by Morocco, Granada, and Murcia  (1264). He claimed the title of Holy Roman emperor (1256), but Gregory  X persuaded him to renounce the claim. His second son became his suc�  cessor as Sancho IV. Alfonso�s court was a center of culture, producing  an influential law code, the Siete Partidas, and establishing the form of  modern Castilian Spanish.</p><p>Alfonso XII (b. Nov. 28, 1857, Madrid, Spain�d. Nov. 25, 1885,  Madrid) Spanish king whose reign (1874-85) inspired hopes for a stable  constitutional monarchy. Alfonso followed his mother, Isabella II, into exile  following her deposition by the revolution of 1868. He was proclaimed  king in 1874 and returned to Spain the next year. His reign was marked  by unaccustomed tranquillity. The most urgent problems�ending the civil  war with the Carlists (see Carlism) and drafting a constitution�were  settled in 1876. Alfonso was popular, and his early death from tubercu�  losis disappointed those who desired a constitutional monarchy.</p><p>Alfonso XIII (b. May 17, 1886, Madrid, Spain�d.

He joined his brother Ethelred I  in confronting a Danish army in Mercia (868). Succeeding his brother as  king, Alfred fought the Danes in Wessex in 871 and again in 878, when  he was the only West Saxon leader to refuse to submit to their authority  and was driven from the kingdom to the island of Athelney. He defeated  the Danes at the Battle of Edington (878) and saved Kent from another  Danish invasion in 885. The next year he took the offensive and captured  London, a success that brought all the English not under Danish rule to  accept him as king. The conquest of the Danelaw by his successors was  enabled by his strategy, which included the construction of forts and a  naval fleet and the reformation of the army. Alfred drew up an important  code of laws (see Anglo-Saxon law) and promoted literacy and learning,  personally translating Latin works by Boethius, Pope Gregory I, and St.  Augustine of Hippo into Anglo-Saxon. The compilation of the Anglo-  Saxon Chronicle was begun under his reign.</p><p>algae \'al-je\ Members of a group of mostly aquatic, photosynthetic  organisms (see photosynthesis) that defy precise definition. They range in  size from the microscopic flagellate Micromonas to giant kelp that reach  200 ft (60 m) in length. Algae provide much of Earth�s oxygen, serve as  the food base for almost all aquatic life, and provide foods and industrial  products, including petroleum products. Their photosynthetic pigments  are more varied than those of plants, and their cells have features not  found among plants and animals. The classification of algae is changing  rapidly because new taxonomic information is being discovered. Algae  were formerly classified into three major groups�the red, brown, and  green seaweeds�based on the pigment molecules in their chloroplasts.  Many more than three groups are now recognized, each sharing a com�  mon set of pigment types. Algae are not closely related to each other in  an evolutionary sense. Specific groups can be distinguished from proto�  zoans and fungi (see fungus) only by the presence of chloroplasts and by  their ability to carry out photosynthesis; these specific groups thus have  a closer evolutionary relationship with the protozoa or fungi than with  other algae. Algae are common on �slimy� rocks in streams (see diatoms)  and as green sheens on pools and ponds. Use of algae is perhaps as old  as humankind; many species are eaten by coastal societies.</p><p>Algardi, Alessandro (b. 1595, Bologna, Papal States�d. June 10,  1654, Rome) Italian sculptor. He  trained in Bologna under the Car�  racci family and in 1625 moved to  Rome, where he designed the stucco  decorations in San Silvestro al Quiri-  nale. He later became the most out�  standing Baroque sculptor in Rome  after Gian Lorenzo Bernini. He was a  prolific sculptor of portrait busts, and  his colossal marble relief of the  Meeting of Attila and Pope Leo  (1646-53) in St. Peter�s Basilica  influenced the development and  popularity of illusionistic reliefs.

Higher algebra (also known  as modem or abstract algebra) includes all of elementary algebra, as well  as group theory, theory of rings, field theory, manifolds, and vector spaces.</p></section><section><p>algebraic equation Mathematical statement of equality between  algebraic expressions. An expression is algebraic if it involves a finite  combination of numbers and variables and algebraic operations (addition,  subtraction, multiplication, division, raising to a power, and extracting a  root). Two important types of such equations are linear equations, in the  form y = ax + b, and quadratic equations, in the form y = ax 2 + bx + c. A  solution is a numerical value that makes the equation a true statement  when substituted for a variable. In some cases it may be found using a  formula; in others the equation may be rewritten in simpler form. Alge�  braic equations are particularly useful for modeling real-life phenomena.</p><p>algebraic geometry Study of geometric objects expressed as equa�  tions and represented by graphs in a given coordinate system. In contrast  to Euclidean geometry, algebraic geometry represents geometric objects  using algebraic equations (e.g., a circle of radius r is defined by x 2 + y 2 =  r 2 ). Objects so defined can then be analyzed for symmetries, intercepts,  and other properties without having to refer to a graph.</p><p>algebraic topology Field of mathematics that uses algebraic struc�  tures to study transformations of geometric objects. It uses functions  (often called maps in this context) to represent continuous transforma�  tions (see topology).

Forced to leave his pulpit after two years because  of allegations of improper activities with youths, he took up writing.  Beginning with Ragged Dick (1868), he wrote more than 100 books that  were almost alike in preaching that through honesty, cheerful persever�  ance, and hard work a poor but virtuous lad would have his just reward  (though it was almost always precipitated by good luck). His books sold  more than 20 million copies, despite consistently weak plots and dialogue,  and Alger was one of the most popular and socially influential writers of  the late 19th century.</p><p>Algeria officially People's Democratic Republic of Algeria</p><p>Country, North Africa. Area: 919,595 sq mi (2,381,741 sq km). Popula�  tion (2005 est.): 32,854,000. Capital: Algiers. Most of the population is  ethnically and linguistically Arab, with a large Berber (Amazigh) minor�  ity. Languages: Arabic, Berber (both official), French. Religion: Islam  (official; predominantly Sunni). Currency: Algerian dinar. Algeria has the  second largest land area (after The Sudan) on the continent. The coast�  line has numerous bays, and the country�s rivers are small and generally  seasonal. Northern Algeria is mountainous and is crossed from east to  west by the Atlas Mountains; its highest point, elevation 7,638 ft (2,328  m), is Mount Chelia. In central and southern Algeria is much of the north�  ern Sahara. Algeria has a developing economy based primarily on the  production and export of petroleum and natural gas. After achieving inde�  pendence, the country nationalized much of its economy but since the  1980s has privatized parts of the economy. Algeria is a republic with two  legislative bodies; its chief of state is the president, and its head of gov�  ernment is the prime minister. Phoenician traders settled there early in the  1st millennium bc; several centuries later the Romans invaded, and by ad  40 they had control of the Mediterranean coast. The fall of Rome in the  5th century led to an invasion by the Vandals and later to a reoccupation  by the Byzantine (Eastern Roman) Empire.

By 1847 France had established military control  over most of the region and by the late 19th century had instituted civil  rule. Popular protest against French rule resulted in the bloody Algerian  War (1954�61); independence was achieved following a referendum in  1962. Beginning in the early 1990s, Islamic fundamentalist opposition to  secular rule led to an outbreak in civil violence between the army and  various Islamic extremist groups.</p><p>Algerian Reformist 'Ulama� \u-la-'ma\, Association of Group  of Muslim religious scholars founded in 1931 that worked to create an  Algerian Muslim identity.

The movement for indepen�  dence began during World War I (1914-18) and gained momentum after  French promises of greater self-rule in Algeria went unfulfilled after  World War II (1939-45). In 1954 the National Liberation Front (FLN)  began a guerrilla war against France and sought diplomatic recognition at  the UN to establish a sovereign Algerian state. Although Algerian fighters  operated in the countryside�particularly along the country�s borders�  the most serious fighting took place in and around Algiers, where FLN  fighters launched a series of violent urban attacks that came to be known  as the Battle of Algiers (1956-57). French forces (that increased to  500,000 troops) managed to regain control but only through brutal mea�  sures, and the ferocity of the fighting sapped the political will of the  French to continue the conflict. In 1959 Charles de Gaulle declared that the  Algerians had the right to determine their own future. Despite terrorist acts  by French Algerians opposed to independence and an attempted coup in  France by elements of the French army, an agreement was signed in 1962,  and Algeria became independent.

When the Spanish threatened it in the  early 16th century, the local emir appealed to the Ottoman corsair Bar-</p><p>barossa, who expelled the Spanish and placed Algiers under the rule of the  Ottoman Empire. Algiers became the major base for the Barbary Coast  pirates for 300 years; their activities were finally curtailed in 1818 by an  American force led by Stephen Decatur. The French took the city in 1830  and made it headquarters for their African colonial empire. In World War  II (1939-45), it became the Allied headquarters in northern Africa and for  a time the provisional capital of France.

In later Islamic hagiography, 'All  was held up as the paradigm of youthful chivalry and virtue by both  Shl'ites and Sunnites.

Cassius Clay took up boxing  at the age of 12 and rose through the  amateur ranks to win the Olympic  light heavyweight crown in 1960.</p><p>His first professional heavyweight  title win was against Sonny Liston in  1964. After defending the title nine  times between 1965 and 1967, he  was stripped of it for refusing induc�  tion into the armed forces following  his acceptance of the teachings of the  Nation of Islam. It was then that he  changed his name to Muhammad  Ali. In 1974 Ali regained his title  after defeating the former champion  Joe Frazier and the then-current  champion George Foreman. He lost  to Leon Spinks in 1978 but later that  year regained the title a third time,  becoming the first heavyweight  champion ever to do so. He retired in 1979, having lost only three of 59  fights. Attempted comebacks in 1980 and 1981 failed. Throughout his  career Ali was known for his aggressive charm, invincible attitude, and  colourful boasts, often expressed in doggerel verse. �I am the greatest�  was his personal credo. Ali�s later years have been marked by physical  decline. Damage to his brain, caused by blows to the head, has resulted  in slurred speech, slowed movement, and other symptoms of Parkinson  disease.</p><p>Alia lemon \al-'yak-mon\ River River, north-central Greece. Rising in  the Grammos Mountains and flowing southeast then northeast for 185 mi  (297 km) into the upper Gulf of Thermai, it is the longest river in Greek  Macedonia.

It was founded as a  Greek colony in 325 bc and was captured in 201 bc by the Romans, who  called it Lucentum. After being ruled by the Moors (718-1249), it was  later incorporated into the kingdom of Aragon in 1265. The city was  besieged by the French in 1709 and by the Federalists of Cartagena in  1873.

It lies between Darwin and Adelaide, virtually in the centre of  the continent. It originated in the 1870s as a station on the Overland Tele�  graph Line. Because of its location, it has become a major shipping point.  Its mild winter climate makes it a popular tourist destination.</p><p>alien In law, one who resides in a country without becoming natural�  ized, retaining instead the citizenship of another country. The laws of most  nations have long afforded aliens certain minimum standards of civilized  treatment but have also restricted their employment and ownership of  property. Under U.S. law, all aliens have had to register since 1940. Reg�  istration cards (�green cards�) entitle them to obtain employment. Like  citizens, aliens are protected by the U.S. Constitution, including the Bill  of Rights and the due-process clause of the 14th Amendment. They remain  subject to limitations under local laws, and residence in the U.S. is not a  right but a privilege granted by Congress.</p><p>Alien and Sedition Acts Four laws passed by the U.S. Congress in  1798, in anticipation of war with France. The acts, precipitated by the  XYZ Affair, restricted aliens and curtailed press criticism of the govern�  ment. Aimed at French and Irish immigrants (who were mostly pro-</p><p>France), they increased the waiting period for naturalization and  authorized expulsion of aliens considered dangerous. The Alien and Sedi�  tion Acts were opposed by Thomas Jefferson and helped propel him to the  presidency. They were repealed or had expired by 1802.</p><p>alienation In the social sciences context, the state of feeling estranged  or separated from one�s milieu, work, products of work, or self. The con�  cept appears implicitly or explicitly in the works of Emile Durkheim, Fer�  dinand Tonnies, Max Weber, and Georg Simmel but is most famously  associated with Karl Marx, who spoke of workers being alienated from  their work and its products under capitalism. In other contexts the term  alienation, like anomie, can suggest a sense of powerlessness, meaning�  lessness, normlessness, social isolation, or cultural- or self-estrangement  brought on by the lack of fit between individual needs or expectations and  the social order.</p><p>alimentary canal or digestive tract Pathway along which food  travels when it is eaten and from which solid wastes are expelled.

He served as an assistant to the U.S. solicitor general (1981-85),  deputy assistant to the U.S. attorney general (1985-87), and U.S. attor�  ney for the district of New Jersey (1987-90). In 1990 he was appointed  by U.S. Pres. George Bush to serve as a judge on the U.S. Court of Appeals  for the Third Circuit, establishing a conservative judicial record. In 2005  he was appointed associate justice of the U.S. Supreme Court by Pres.  George W. Bush to fill the seat of retiring justice Sandra Day O'Connor;  he was confirmed by the U.S. Senate the following year.</p><p>aliyah \a-�le-ya\ Hebrew "ascending" In Judaism, the honour,  accorded to a worshiper, of being called up to read an assigned passage  from the Torah at Sabbath morning services; or Jewish immigration to  Israel. Because the passage assigned for each Sabbath morning service is  subdivided into a minimum of seven sections, at least seven different per�  sons are called up for these readings. Aliyah in the sense of immigration  to Israel is ongoing but also occurs in waves. The first two waves of  immigration occurred in 1882-1914, the next three in 1919-39. The sixth  aliyah (1945-48) brought many Holocaust survivors. Later waves of  immigration included Falasha from Ethiopia, emigres from the former  Soviet Union, and others.

More  broadly, ammonium hydroxide (see ammonia) and soluble hydroxides of  the alkaline earth metals are also called alkalies. Strong bases that turn lit�  mus paper blue, they react with acids to yield salts, are caustic, and in con�  centrated form corrode tissues. Sodium hydroxide (caustic soda) and  potassium hydroxide (caustic potash) are very important industrial chemi�  cals, used in the manufacture of soaps, glass, and many other products.  The mineral trona, a compound of sodium carbonate and bicarbonate, is  one naturally occurring alkali. It may be mined or recovered from dry  lake beds.</p><p>alkali feldspar Any of several common silicate minerals that often  occur as whitish to variously coloured, glassy crystals. The alkali feld�  spars may be regarded as mixtures of sodium aluminosilicate (NaAlSi 3 0 8 )  and potassium aluminosilicate (KAlSi 3 0 8 ). Both the sodium and potas�  sium aluminosilicates have several distinct forms, each with a different  structure. Alkali feldspars are used in the manufacture of glass and ceram�  ics; transparent, highly coloured, or iridescent varieties are sometimes  used as gemstones. They are primarily important, however, as constitu�  ents of rocks (see plagioclase).</p><p>alkali metal Any of the six chemical elements in the leftmost group of  the periodic table (lithium, sodium, potassium, rubidium, cesium, and francium).  They form alkalies when they combine with other elements. Because their</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>alkaline earth metal &#x25BA; Allen I 49</p><p>atoms have only one electron in the outermost shell, they are very reac�  tive chemically (they react rapidly, even violently, with water), form  numerous compounds, and are never found free in nature.</p><p>alkaline earth metal Any of the six chemical elements in the second  leftmost group of the periodic table (beryllium, magnesium, calcium, strontium,  barium, and radium). Their name harks back to medieval alchemy. Their  atoms have two electrons in the outermost shell, so they react readily, form  numerous compounds, and are never found free in nature.</p><p>alkaloid Basic (see base) organic compounds of plant origin, contain�  ing combined nitrogen. Alkaloids are amines, so their names usually end  in �ine� (e.g., caffeine, nicotine, morphine, quinine). Most have complex  chemical structures of multiple ring systems. They have diverse, impor�  tant physiological effects on humans and other animals, but their func�  tions in the plants that produce them are poorly understood. Some plants  (e.g., opium poppy, ergot fungus) produce many different alkaloids, but most  produce only one or a few. Certain plant families, including the poppy fam�  ily (Papaveraceae) and the nightshade family (Solanaceae), are particularly  rich in them. Alkaloids are extracted by dissolving the plant in dilute acid.</p><p>Alkamenes See Alcamenes</p><p>alkane or paraffin Any of a class of hydrocarbons whose molecules  consist only of carbon and hydrogen atoms joined by single covalent  bonds (general formula C�H (2n + 2 ))- The simplest is methane (CH 4 ).  Alkanes with more than three carbon atoms may have straight and  branched isomers. Cycloalkanes have ring structures (but are not aromatic  compounds) with two fewer hydrogen atoms per molecule than the cor�  responding alkane; many have more than one ring. Commercial sources  include petroleum and natural gas. Uses, often as mixtures, include fuels,  solvents, and raw materials.

It is celebrated on November 1 in the  Western churches and on the first Sunday after Pentecost in the Eastern  churches. The first general observance of All Saints� Day was ordered by  Pope Gregory IV in 837. In medieval England the festival was called All  Hallows, and its eve is still known as Halloween.</p><p>All Souls' Day In the Roman Catholic church, a day commemorating  all the Christians believed to be in purgatory. Celebrated on November  2, it was first established by Odilo (d. 1049), abbot of Cluny, in the 11th  century, and it was widely celebrated by the 13th century. The date fol�  lows All Saints' Day, with the idea that remembering the saints in heaven  should be followed by remembering the souls awaiting release from pur�  gatory. Roman Catholic doctrine holds that the prayers of the faithful on  earth will help cleanse these souls in order to prepare them for heaven.</p><p>Allah Arabic "God" Standard Arabic word for God, used by Arab  Christians as well as by Muslims. According to the Qur�an, Allah is the  creator and judge of humankind, omnipotent, compassionate, and merci�  ful. The Muslim profession of faith affirms that there is no deity but God  and emphasizes that he is inherently one: �nothing is like unto him.�  Everything that happens occurs by his commandment; submission to God  is the basis of Isiam.

An ancient holy city sacred to Hindu  pilgrims, it is the site of the Pillar of Ashoka (erected c. 240 bc). The  Mughal emperor Akbar founded the present-day city in 1583; it was ceded  to the British in 1801. Allahabad was the scene of a serious outbreak in  the 1857 Indian Mutiny.

The Alleghenian orogeny is most pronounced in the central and  southern Appalachian Mountains and produced the different effects in  various subregions: compressional folding and faulting of the Valley and  Ridge Province, westward thrusting of the Blue Ridge, and folding and  minor metamorphism and igneous intrusion in the Piedmont Province. It  may have resulted from the collision (see plate tectonics) of the central  and southern Appalachian continental margin with that of North Africa in  the Permian period.</p><p>Allegheny \,al-3-'ga-ne\ Mountains Ranges of the Appalachian sys�  tem in Pennsylvania, Maryland, Virginia, and West Virginia, U.S., west  of and generally parallel to the Blue Ridge Mountains. Part of the Allegh�  eny Plateau that spans the entire upland area from the Cumberland Pla�  teau to the Mohawk Valley in New York, the Allegheny Mountains extend  some 500 mi (800 km) south-southwestward, with heights of more than  4,800 ft (1,460 m). The eastern slope is sometimes called the Allegheny  Front.</p><p>Allegheny River River in Pennsylvania and New York, U.S. It rises  in Potter county. Pa., loops northwest into New York, turns back into  Pennsylvania, and unites with the Monongahela to form the Ohio River at  Pittsburgh, Pa. It is 325 mi (523 km) long; its chief tributaries are the  Clarion, the Kiskiminetas, and French Creek. Several dams make the river  navigable from Pittsburgh to East Brady, Pa.</p><p>allegory Work of written, oral, or visual expression that uses symbolic  figures, objects, and actions to convey truths or generalizations about  human conduct or experience. It encompasses such forms as the fable and  parable. Characters often personify abstract concepts or types, and the  action of the narrative usually stands for something not explicitly stated.  Symbolic allegories, in which characters may also have an identity apart  from the message they convey, have frequently been used to represent  political and historical situations and have long been popular as vehicles  for satire. Edmund Spenser�s long poem The Faerie Queen is a famous  example of a symbolic allegory.</p><p>allele \3-'lel\ Any one of two or more alternative forms of a gene that  may occur alternatively at a given site on a chromosome. Alleles may occur  in pairs, or there may be multiple alleles affecting the expression of a par�  ticular trait. If paired alleles are the same, the organism is said to be  homozygous for that trait; if they are different, the organism is heterozy�  gous. A dominant allele will override the traits of a recessive allele in a  heterozygous pairing (see dominance and recessiveness). In some traits,  alleles may be codominant (i.e., neither acts as dominant or recessive).  An individual cannot possess more than two alleles for a given trait. All  genetic traits are the result of the interactions of alleles.</p><p>allemande Val-o-.mandX Processional couple dance with stately flow�  ing steps, fashionable in the 16th century, especially in France. A line of  couples extended their paired hands forward and paraded back and forth  the length of the ballroom.

In the late 17th century a stylized version of the dance  in 14 time began to be used by composers as the first movement of the  SUITE.</p><p>Allen, Ethan (b. Jan. 21, 1738, Litchfield, Conn.�d. Feb. 12, 1789,  Burlington, Vt., U.S.) American soldier and frontiersman. After fighting  in the French and Indian War (1754-63), he settled in what is now Ver�  mont. At the outbreak of the American Revolution, his force of Green  Mountain Boys (organized in 1770) helped defeat the British in the Battle  of Ticonderoga (1775). As a volunteer with troops commanded by Gen.  Philip Schuyler, he attempted to take Montreal but was captured by the  British and held prisoner until 1778. He returned to Vermont, where he  worked for statehood. Failing to achieve this, he attempted to negotiate  the annexation of Vermont to Canada.</p><p>Allen, Mel orig. Melvin Allen Israel (b.

A Methodist convert at 17,  he was licensed to preach five years later. By 1786 he had purchased his  freedom and settled in Philadelphia, where he joined St. George�s Meth�  odist Episcopal Church. Racial discrimination prompted him to withdraw  in 1787, and he turned an old blacksmith shop into the first black church  in the U.S. Allen and his followers built the Bethel African Methodist  Church, and in 1799 he was ordained as its minister. In 1816 he organized  a conference of black leaders to form the African Methodist Episcopal  Church, of which he was named the first bishop.</p><p>Allen, Steve orig.

His early films,  such as Bananas (1971) and Sleeper (1973), combined highbrow comedy  and slapstick. Later romantic comedies such as Annie Hall (1977), which  won him two Academy Awards, and Manhattan (1979) offered a bitter�  sweet view of New York life.

He fought in the South African War and served as  inspector general of cavalry (1910-14). In World War I, he commanded  with distinction in the Middle East. His victory over the Turks at Gaza  (1917) led to the capture of Jerusalem, and his victory at Megiddo, along  with his capture of Damascus and Aleppo, ended Ottoman power in Syria.  His success was partly due to his innovative use of cavalry and other  mobile forces, and he is remembered as the last great British leader of  mounted cavalry. As high commissioner for Egypt (1919-25), he steered  that country to recognition as a sovereign state (1922).</p><p>Allende \a-'yen-da\ (Gossens), Salvador (b. July 26, 1908, Val�  paraiso, Chile�d. Sept. 11, 1973, Santiago) Socialist president of Chile  (1970-73). Of upper-middle-class background, Allende took a degree in  medicine and in 1933 helped found Chile�s Socialist Party. He ran for  president unsuccessfully three times before winning narrowly in 1970. He  attempted to restructure Chilean society along socialist lines while retain�  ing democracy, civil liberties, and due process of law, but his efforts to  redistribute wealth resulted in stagnant production, food shortages, rising  inflation, and widespread strikes. His inability to control his radical sup�  porters further alienated the middle class. His policies dried up foreign  credit and led to a covert campaign by the U.S. Central Intelligence Agency  to destabilize the government. He was overthrown in a violent military  coup, during which he died by gunshot, reportedly self-inflicted. He was  replaced by Gen. Augusto Pinochet.

During the American Revolution, the Liberty Bell was  moved there for safekeeping. It is a major iron and mining centre.</p><p>allergy Exaggerated reaction by the body to foreign substances that are  harmless to most people. Those substances, called allergens or antigens,  may include pollens, drugs, dusts, foods, and other items. Immediate aller�  gic reactions result from genetic predisposition or sensitization by previ�  ous exposure. Blood vessels dilate and bronchial air passages constrict.  A severe reaction (anaphylaxis) can obstruct breathing and may be fatal.</p><p>Delayed allergic responses (e.g., contact dermatitis) appear 12 hours or  more after exposure. Avoiding allergens and taking antihistamines can pre�  vent or treat allergies. When avoidance is not feasible and antihistamines  do not relieve symptoms, desensitization can be attempted.</p><p>alliance In international politics, a union for joint action of various  powers or states. Examples include the alliance of the European powers  and the U.S. against Germany and its allies during World War II and the  alliance of the NATO states against the Soviet Union and its allies dur�  ing the Cold War. Many alliances rest on the principle of collective secu�  rity, through which an attack on one member is considered an attack on  all members. Major alliances formed after World War II include the  ANZUS Pact, the Arab League, ASEAN, the Organization of American  States, the Southeast Asia Treaty Organization, and the Warsaw Pact.</p><p>Alliance for Progress International development program. Initiated  by the U.S. and joined by 22 Latin American countries in 1961, it aimed  to strengthen democratic government and promote social and economic  reforms in Latin America. The program, which provided loans and aid  from the U.S. and the international financial community, built some  schools and hospitals, but by the early 1970s it was widely viewed as a  failure. Significant land reform was not achieved, population growth out�  stripped gains in health and welfare, and the U.S. willingness to support  military dictators to prevent communism from gaining a foothold sowed  distrust and undermined the reforms the Alliance was intended to pro�  mote.</p><p>Alliance Israelite Universelle Xal-'yaVis-ra-el-'et-il-ne-ver-'seL  Political organization founded in France in 1860 for the purpose of pro�  viding assistance to Jews. Its founders were a group of French Jews who  had the resources to help those who were poor, offering political support,  helping individuals emigrate, and eventually setting up Jewish education  programs in eastern Europe, the Middle East, and North Africa. In 1945  it expressed support for political Zionism (the establishment of a Jewish  state), and in 1946 its diplomatic activities were taken over by the Con�  sultative Council of Jewish Organizations in New York City.</p><p>Allied Powers or Allies Nations allied in opposition to the Central  Powers in World War I or to the Axis Powers in World War II. The origi�  nal Allies in World War I�the British Empire, France, and the Russian  Empire�were later joined by many other countries, including Portugal,  Japan, and Italy. Other nations joining the Allies, including the U.S. after  1917, were called Associated Powers, a term emphasized by Pres. Woo�  drow Wilson to preserve the U.S.�s free hand in the war. In World War II  the major Allied Powers were Britain, France, the Soviet Union, the U.S.,  and China. More generally, the Allies included all the wartime members  of the United Nations, the 1942 signatories to the Declaration of the UN.</p><p>alligator Either of two species of long-snouted reptiles constituting the  genus Alligator (family Alligatoridae, order Crocodilia). Alligators differ  from crocodiles in snout shape and tooth placement. Living in large bod�  ies of water such as lakes, swamps, and rivers, these lizardlike carnivores  use their powerful tail for defense and swimming. The eyes, ears, and  nostrils, located on top of the long head, project above the water�s sur�  face. Alligators dig burrows in which they shelter from danger and hiber�  nate in cold weather. The once-endangered American alligator of the  southeastern U.S. may grow to 19 ft (5.7 m) long but usually ranges from  6 to 12 ft (1.8 to 3.7 m) long. The Chinese alligator of the Chang (Yangtze)  River region, which grows to 5 ft (1.5 m), is critically endangered.</p><p>Alligator (Alligator mississippiensis)</p><p>P.

Allium species are found in most regions of the world except the  tropics and New Zealand and Australia. Some are cultivated as ornamen�  tal border plants.</p><p>allocation of resources Apportionment of productive assets among  different uses. The issue of resource allocation arises as societies seek to  balance limited resources (capital, labour, land) against the various and  often unlimited wants of their members. Mechanisms of resource alloca�  tion include the price system in free-market economies and government  planning, either in state-run economies or in the public sectors of mixed  economies. The aim is always to allocate resources in such a way as to  obtain the maximum possible output from a given combination of  resources.</p><p>Allosaurus X.al-o-'sor-osV Large carnivorous dinosaur of a group simi�  lar to the tyrannosaurs, found as fossils primarily in Late Jurassic rocks  of North America. It weighed 2 tons (1,800 kg) and grew to 35 ft (10.5  m) long. Its well-developed tail, half of its total body length, probably  functioned as a counterbalance for the body. Allosaurus walked on its two  hind limbs and probably used the much smaller forelimbs for grasping.  Equipped with powerful, flexible jaws, allosaurs likely preyed on  medium-sized dinosaurs; they were possibly scavengers that hunted in  groups. Some related allosaurs ( Giganotosaurus, Carcharodonotosaurus)  may have been larger than Tyrannosaurus rex.</p><p>allosteric control \,a-lo-'ster-ik\ Inhibition or activation of an enzyme  by a small regulatory molecule that interacts with the enzyme at a site  (allosteric site) other than the active site (at which catalytic activity  occurs). The interaction changes the shape of the enzyme, thus affecting  the active site of the usual complex between the enzyme and its substrate  (the substance on which the enzyme acts). As a result, the enzyme�s abil�  ity to catalyze a reaction (see catalysis) is either inhibited or enhanced. If  the regulatory molecule inhibits an enzyme in the pathway of its own  synthesis, the control is said to be feedback inhibition. Allosteric control  enables the cell to regulate needed substances rapidly.</p><p>allotrope Va-lo-.tropX Any of two or more forms of the same chemical  element. They may have different arrangements of atoms in crystals of the  solid�for example, graphite and diamond for carbon �or different num�  bers of atoms in their molecules �for example, ordinary oxygen (0 2 ) and  ozone (0 3 ). Other elements that have allotropes include tin, sulfur, anti�  mony, ARSENIC, SELENIUM, and PHOSPHORUS.</p><p>alloy Metallic substance composed of two or more elements, as either a  mixture, compound, or solid solution. The components of alloys are ordi�  narily themselves metals, though carbon is an essential nonmetal compo�  nent of steel. Alloys are usually produced by melting the mixture of  ingredients. The value of alloys was discovered in very ancient times;  brass (copper and zinc) and bronze (copper and tin) were especially impor�  tant. Today the most important are the alloy steels, which have a wide  range of special properties, including hardness, toughness, corrosion resis�  tance, magnetizability, and workability.</p><p>Allport, Gordon W(illard) (b. Nov. 11, 1897, Montezuma, Ind.,  U.S.�d. Oct. 9, 1967, Cambridge, Mass.) U.S. psychologist. He taught  at Harvard University (1930-67), becoming noted for his theory of per�  sonality, which focused on the adult self rather than on childhood or  infantile emotions and experiences, set forth in books such as Personal�  ity (1937). In The Nature of Prejudice (1954) he made important contri�  butions to the analysis of prejudice.</p><p>allspice Tropical evergreen tree ( Pimento dioica) of the myrtle family,  native to the West Indies and Central  America and valued for its berries,  the source of a highly aromatic spice.</p><p>Allspice was so named because the  flavour of the dried berry resembles  a combination of cloves, cinnamon,  and nutmeg.

Nov. 5, 1779, Allston plantation. Brook  Green Domain on Waccamaw River, S.C., U.S.�d. July 9, 1843, Cam-  bridgeport, Mass.) U.S. painter and writer. He studied at Harvard Uni�  versity and at London�s Royal Academy (with Benjamin West). He settled  in Massachusetts in 1830 and became the most important first-generation  U.S. Romantic painter. His large landscapes depict the mysterious and  dramatic aspects of nature. He later relied on mood and reverie in smaller,  more dreamlike images. He also wrote poetry and fiction, and his theo�  ries on art were published posthumously as Lectures on Art (1850).</p><p>alluvial deposit Material deposited by rivers. It consists of silt, sand,  clay, and gravel, as well as much organic matter. Alluvial deposits are  usually most extensive in the lower part of a river�s course, forming  floodplains and deltas, but they may form at any point where the river  overflows its banks or where the flow of a river is checked. They yield  very fertile soils, such as those of the deltas of the Mississippi, Nile,  Ganges and Brahmaputra, and Huang (Yellow) rivers. They contain most  of the world�s supply of tin ore, as well as, in some regions, gold, plati�  num, and gemstones.</p><p>Almagest Val-mo-jestN Astronomical and mathematical encyclopedia  compiled c. ad 140 by Ptolemy. It served as the basic guide for Arab and  European astronomers until the 17th century. The name derives from the  Arabic for �the greatest.� Its 13 books cover such topics as the geocen�  tric (Earth-centred), or Ptolemaic, model of the solar system; eclipses; the  coordinates and sizes of certain fixed stars; and the distances to the Sun  and the Moon.</p><p>Almagro \al-'ma-gro\, Diego de (b. 1475, Almagro, Castile�d.  1538, Cuzco, Peru) Spanish soldier who played a leading role in the  Spanish conquest of Peru. Following service in the Spanish navy, he  arrived in South America in 1524 and, with Francisco Pizarro, led the  expedition that conquered the Inca empire in what is now Peru. Bitter  enmity arose between the two men, and Almagro imprisoned Pizarro�s  two brothers for insubordination during an Indian rebellion. Pizarro then  defeated Almagro�s army and had his former friend put to death.</p><p>almanac Book or table containing a calendar of a given year, with a  record of various astronomical phenomena, often with weather prognos�  tications, seasonal suggestions for farmers, and other information. The  first printed almanac appeared in the mid 15th century. Benjamin Franklin  began his famous Poor Richard�s almanacs in 1732. A form of folk lit�  erature, 18th-century almanacs furnished useful and entertaining infor�  mation where reading matter was scarce; a surviving example is the Old  Farmer�s Almanac. Modern almanacs are often annual publications con�  taining statistical, tabular, and general information.</p><p>Alma-Tadema Val-mo-'ta-do-moV, Sir Lawrence (b. Jan. 8, 1836,  Dronrijp, Neth.�d. June 25, 1912, Wiesbaden, Ger.) Dutch-British  painter. After studies at the Antwerp Academy, he visited Italy (1863) and  became enamoured of Greco-Roman antiquity and Egyptian archaeology;  the ancient world was to provide his primary themes. After settling in  London in 1870, he excelled at the accurate re-creation of ancient scenes,  exotic costumes, and the sensuous depiction of beautiful women against  backgrounds of marble, bronze, and silk. Such figurative images com�  bined sentimentality and anecdote. He was elected to the Royal Academy  in 1879 and knighted in 1899. Alma-Tadema�s work was immensely  popular in his day, but it went out of favour after his death.</p><p>Almaty Xol-'ma-t e\formerly Alma-Ata W-'ma-o-'taV City (pop., 1999:  1,129,400), southeastern Kazakhstan.

The Almohad  leader Ibn Tumart began his rebellion in the 1120s. Marrakech was cap�  tured in 1147 under the leadership of his successor �Abd al-Mu�min. By the  1170s all of the Maghrib was under unified control for the only time in  its history, and the Almohads also controlled Muslim Spain. Their rule  was marked by, on the one hand, the cultivation of science and philoso�  phy and, on the other, efforts at religious unification by compelling Jews  and Christians to convert or emigrate. They lost control of Spain to the  Christians in 1212 and of their North African provinces to the Hafsid  dynasty in Tunis (1236) and the Marinids in Marrakech (1269).</p><p>almond Tree ( Prunus dulcis) in the rose family, native to South Asia;  also its edible seed, or nut. The tree, growing somewhat larger and living  longer than the peach, is strikingly beautiful when in flower. The nuts are  either sweet or bitter. Sweet almonds are the edible type consumed as nuts  and used in cooking. The extracted oil of bitter almonds is used to make  flavouring extracts for foods and liqueurs. Almonds provide small  amounts of protein, iron, calcium, phosphorus, and B vitamins and are  high in fat. They are commonly used in confectionery baking and in  marzipan, a traditional European candy.</p><p>Almoravid V.al-mo-'ra-vodX dynasty Arabic al-Murabitun (1056-  1147) Berber confederation that succeeded the Fajimid dynasty in the Magh�  rib. It flourished in the 11th and early 12th centuries. Its founder, c Abd  Allah ibn Yasln, was a Muslim scholar of the Malik! school who used  religious reform as a means of gaining followers in the mid-11th century.  The Almoravids took over Morocco and then the rest of the Maghrib fol�  lowing the decline of the Zlrid dynasty. By 1082 they ruled Algiers. By  1110 they also controlled Muslim Spain, but the Christians began to win  back territory in 1118. In the 1120s another Berber coalition, the Almo�  hads, started a rebellion, eventually displacing the Almoravids.</p><p>aloe Any shrubby succulent plant of the genus Aloe, in the lily family.  Native to Africa, most of the 200 or so species have a rosette of leaves at  the base but no stem. Several are cultivated as ornamentals.

The alpaca, guanaco, llama, and vicuna are closely  related and are known collectively as lamoids. Domesticated several thou�  sand years ago by Indians of the Andes Mountains, the alpaca has a slen�  der body, a long neck and legs, a small head, a short tail, and large, pointed  ears. Alpacas stand about 35 in. (90 cm) at the shoulder and weigh 120-  145 lbs (54-65 kg). They are found in central and southern Peru and  western Bolivia, on marshy ground at high altitudes. They are the most  important of the lamoids for wool production.</p><p>Alp-Arslan Valp-ar-'slan\ (b. c. 1030�d. November? 1072/January  1073) Second sultan of the Seljuq dynasty, who added Georgia, Armenia,  and much of Anatolia to his domains of Khorasan and western Iran. He  preferred conquest to governing and left the administration of his empire  to his famous vizier, Nizam al-Mulk. In 1071 his victory over the Byzan�  tine Empire at the Battle of Manzikert opened the door for the eventual  Turkish conquest of Anatolia. He died a year later when mortally wounded  by a prisoner during a quarrel.</p><p>Alpha Centauri Triple star in the constellation Centaurus, the faintest  component of which, Proxima Centauri, is currently the closest star to the  Sun (about 4.2 light-years away). The two brighter components are about  0.2 light-year farther from the Sun. As seen from Earth, the system is the  third brightest star (after Sirius and Canopus); Proxima is indistinguish�  able as a separate star to the unaided eye. Alpha Centauri can be seen  from Earth�s surface only from points south of about 40� N.</p><p>alpha decay Type of radioactive disintegration (see radioactivity) in  which some unstable atomic nuclei dissipate excess energy by spontane�  ously ejecting an alpha particle. Alpha particles have two positive charges  and a mass of four atomic mass units; they are identical to helium nuclei.  Though they are emitted at speeds about one-tenth that of light, they are  not very penetrating and have ranges in air of about 1-4 in. (2.5-10 cm).  Alpha decay commonly occurs in elements with atomic numbers greater  than 83 (bismuth), but can occur in some rare-earth elements in the  atomic-number range of 60 (neodymium) to 71 (lutetium). Alpha decay  half-lives range from about a microsecond (10 -6 second) to billions of  years (10 17 seconds).</p><p>alphabet Set of symbols or characters that represent language�s sounds  in writing. Each character usually represents a simple vowel, a diphthong  (two vowels), or one or two consonants. A writing system in which one  character represents a whole syllable is called a syllabary. The first alpha�  bet is believed to have been the North Semitic, which originated in the  eastern Mediterranean region between 1700 and 1500 bc. Alphabets that  arose in the next 500 years included the Canaanite and Aramaic, from  which the modern Hebrew and Arabic alphabets descended, and the Greek  (ancestor of the Latin alphabet), considered the first true alphabet because  it includes both consonants and vowels. Scholars have attempted to estab�  lish an exact correspondence between each sound and its symbol in new  alphabets such as the International Phonetic Alphabet.</p><p>Alpheus \al-'fe-3s\ River River, southern Greece. About 75 mi (120  km) long, it is the longest river in the Peloponnese. It rises in Arcadia and  flows northwest through southern Elias into the Ionian Sea. Olympia is on  its northern bank. It shares its name with the ancient river god, and it  figures in Greek legend, including Hercules� cleaning of the Augean  stables, and in Samuel Taylor Coleridge�s poem �Kubla Khan.�</p><p>Alpine orogeny \o-'ra-j3-ne\ Mountain-building event that affected a  broad segment of southern Europe and the Mediterranean region during  the middle Tertiary period. It produced intense metamorphism, crumpling of  rock strata, and uplift accompanied by faulting.

Speed events are contested in single runs down  longer, steeper, faster courses, with fewer turns than those featured in the  technical events. Alpine skiing was first included in the Olympic Games  in 1936. See also cross-country skiing; Nordic skiing.</p><p>Alps Mountain system, south-central Europe. The Alps extend in a cres�  cent about 750 mi (1,200 km) from the Mediterranean coast between  France and Italy to Vienna and cover more than 80,000 sq mi (207,000  sq km). Several peaks rise above 10,000 ft (3,000 m); the highest is Mont  Banc. The Alps form a divide between the Atlantic Ocean, the Mediter�  ranean Sea, and the Black Sea and give rise to several major European  rivers, including the Rhone, Danube, and Po. Glaciers cover about 1,500  sq mi (3,900 sq km), mostly at elevations above 10,000 ft (3,000 m). The  Saint Gotthard Pass is one of the Alps�s notable tunnels. Grenoble, Inns�  bruck, and Bolzano are major Alpine cities.</p><p>Alsace-Lorraine \al-'sas-l6-Tan\ Area, eastern France.

Altaic lan�  guages are spoken across Eurasia by more than 140 million people (the  overwhelming majority of whom speak Turkic languages). Most scholars  consider Altaic itself to be a family, of proven genetic relationship, though  a minority attribute similarities in the languages to borrowings and areal  convergence. The Uralic and Altaic language families were once believed  to form a superfamily, but reliable sound correspondences have not been  demonstrated, and the numerous similarities between the two are now  attributed to areal influences.</p><p>Altamira \,al-t3-'mir-3\ Cave near Santander, northern Spain, famous  for its magnificent prehistoric paintings and engravings. The paintings,  dating to 14,000-12,000 bc, were first described in 1880. Altamira cave  is 890 ft (270 m) long. The roof of the main chamber is covered with  paintings, chiefly of bison, in vivid red, black, and violet. Other figures,  in a simpler style, include wild boars, horses, and a hind, as well as eight  engraved anthropomorphic figures and various handprints and hand out�  lines. Engraved artifacts and other material remains suggest that the site  may have been a centre for seasonal gatherings.

He established a Chinese-style gov�  ernment in his homeland and concluded a peace treaty with Ming-dynasty  China in 1571. He converted the Mongols to the reformed, or Dge-lugs-  pa, sect of Tibetan Buddhism. In 1578 Altan granted the head of the sect  the title of Dalai Lama. With Mongol military aid, later Dalai Lamas  crushed the more established Karma-pa (Red Hat) sect in Tibet to become  Tibet�s spiritual and temporal rulers. See also Gtsang dynasty.</p><p>altar Raised structure or place used for sacrifice, worship, or prayer.  Altars probably originated with the belief that objects or places (e.g., a  tree or spring) were inhabited by spirits or deities worthy of prayers or  gifts. Sacrifice to deities required a structure on which the victim could be  killed and blood channeled off or flesh burned. In ancient Israel, the altar  was a rectangular stone with a hollo wed-out basin on top. The ancient  Greeks placed altars (see baetylus) in homes, marketplaces, public build�  ings, and sacred groves. Roman altars were similarly ubiquitous and were  often decorated with relief sculptures. Christians at first did not use altars,  but by the 3rd century the table on which the Eucharist was celebrated  was regarded as an altar. It became the focus of the mass in Christian  churches and in Western churches was often adorned by a baldachin and  an ALTARPIECE.</p><p>altarpiece Painting, relief, sculpture, screen, or decorated wall stand�  ing on or behind an altar in a Christian church. The images depict holy  personages, saints, and biblical subjects. There are two types of altar-  pieces: the reredos, which rises from the floor behind the altar, and the  retable, which stands on the altar itself or on a pedestal behind it. The  diptych is an altarpiece consisting of two panels; a triptych, three panels;  and a polyptych, four or more panels. Altarpieces vary in size; some are  small and portable, some are huge and stationary, and some have mov�  able wings that can be opened and closed. The practice of erecting sculp�  tural altarpieces dates from the 11th century; altar paintings became  common in the 14th century.</p><p>Altdorfer Valt-.dor-farV, Albrecht (b. c. 1480�d. Feb. 12, 1538,  Regensburg) German painter and printmaker. He was the leading artist of  the Danube school. Most of his works depict religious subjects, but he was</p><p>one of the first artists to develop landscape painting as an independent  genre, specializing in sunset lighting and ruins in twilight. His drawings  demonstrate these skills in black with white highlights on dark paper. The  influence of Albrecht DOrer is evident in his miniature engravings and  woodcuts. From 1526 until his death he was town architect of Regens�  burg; no architectural work of his is known to have survived.</p><p>Alte Pinakothek Val-to-.pe-na-ko-'tekX German "Old Museum of</p><p>Painting" Art museum, one of several collections within the Bavarian  State Picture Galleries in Munich, Germany, and one of the great muse�  ums of the world. It specializes in European painting from the Middle  Ages through the late 18th century; its core collections once belonged to  several early Bavarian electors palatine. The building is a 1957 recon�  struction of the original 19th-century gallery, destroyed in World War II.  Other state museums include the Neue (�New�) Pinakothek, which is  based on the private collections of Bavarian kings and features 18th�  20th-century European paintings and sculpture; the Schack Gallery col�  lection of late Romantic German painting; and the State Gallery of  Modem Art.</p><p>alternating current (AC) Flow of electric charge that reverses peri�  odically, unlike direct current. It starts from zero, grows to a maximum,  decreases to zero, reverses, reaches a maximum in the opposite direction,  returns again to zero, and repeats the cycle indefinitely. The time taken  to complete one cycle is called the period (see periodic motion), and the  number of cycles per second is the frequency; the maximum value in either  direction is the current�s amplitude. Low frequencies (50-60 cycles per  second) are used for domestic and commercial power, but frequencies of  around 100 million cycles per second (100 megahertz) are used in tele�  vision and of several thousand megahertz in radar and microwave com�  munication. A major advantage of alternating current is that the voltage  can be increased and decreased by a transformer for more efficient trans�  mission over long distances. Direct current cannot use transformers to  change voltage. See also electric current.</p><p>alternation of generations In biology, alternation of a sexual phase  (gametophyte) and a nonsexual phase (sporophyte) in the life cycle of an  organism. The two phases, or generations, are often distinct in structure  and sometimes in chromosome makeup. Alternation of generations is com�  mon in algae, fungi (see fungus), Mosses, ferns, and seed plants. The char�  acter and extent of the two phases vary greatly among different groups  of plants and algae. During the course of evolution, the gametophyte stage  has been progressively reduced. Thus in higher (vascular) plants, the  sporophyte is the dominant phase; in more primitive, nonvascular plants  the gametophyte is dominant. Among animals, many invertebrates (e.g.,  protozoans, jellyfish, flatworms) have an alternation of sexual and asexual  generations.</p><p>alternative energy Any of various renewable power sources to use  in place of fossil fuels and uranium. Fusion devices (see nuclear fusion) are  believed by some to be the best long-term option, because their primary  energy source would be deuterium, abundant in ordinary water. Other tech�  nologies include solar energy, wind power, tidal power, wave power, hydro�  electric power, and geothermal energy. The amount of energy in such  renewable and virtually pollution-free sources is large in relation to world  energy needs, yet at present only a small portion of it can be converted  to electric power at reasonable cost.</p><p>alternative medicine or complementary medicine Any of a</p><p>broad range of healing approaches not used in conventional Western medi�  cine. Many are holistic (see holistic medicine); many also emphasize pre�  vention and education. Alternative therapies include acupuncture,  aromatherapy, Ayurveda medicine, Chinese medicine, chiropractic, herbal  medicine, homeopathy, massage, meditation, naturopathy, therapeutic touch,  and Yoga. Though considered alternative in the West, such medicine is  the main source of health care for up to 80% of people in less-developed  countries. Some alternative-medicine practices are useless or harmful;  others are effective and may offer treatments in areas where conventional  approaches have not succeeded (e.g., chronic disorders).</p><p>alternator Source of direct electric current in modern vehicles for igni�  tion, lights, fans, and other uses.

In the 1870s  he moved to Chicago, where he accumulated a small fortune in real estate  and became active in Democratic Party politics. In 1892 he won the gov�  ernorship as a reformist candidate. In 1893, at the urging of Clarence Dar-  row and labour leaders, he granted clemency to three men convicted of  complicity in the Haymarket Riot. The controversial pardon provoked an  outcry from conservatives and contributed to his defeat for reelection in  1896, though Altgeld�s decision later gained wide approval in judicial  circles.</p><p>altimeter \al-'tim-3t-3r\ Instrument that measures the altitude of the  land surface or of any object, such as an airplane. The mechanical pres�  sure altimeter measures atmospheric pressure relative to sea level through  a series of bellows, gears, and springs, which move pointers on a dial.  Radio altimeters measure the distance of an aircraft above the ground  rather than above sea level by indicating the time a pulse of radio energy  takes to travel from the aircraft to the ground and back; they are used in  automatic navigation and blind-landing systems.</p><p>Altiplano \,al-ti-'pla-n6\ Spanish "High Plateau" Region, south�  eastern Peru and western Bolivia.

The second-highest part  in four-part music, it is normally sung by women. The name derives from  contratenor altus , the part above the tenor part. It is used for some instru�  ments that play principally in the alto range (alto saxophone, alto flute,  etc.). See also countertenor.</p><p>Altria Group, Inc. U.S. holding company with interests in tobacco,  foods, and financial services. Formerly called Philip Morris Cos., Inc.,  the group changed its name to Altria in January 2003. Its holdings include  Kraft Foods, Inc. (including Nabisco), Philip Morris International Inc.,  and Philip Morris USA Inc. (see Philip Morris tobacco companies), and an  interest in SABMiller PLC, which was created in 2002 from the merger  of South African Breweries PLC and Miller Brewing Co. Philip Morris  had acquired the Miller Brewing Co. in 1969. It continued to reduce its  dependence on tobacco by acquiring General Foods (1985), Kraft Foods  (1988), and Nabisco (2000), among others. In 1998, as part of the settle�  ment of a suit brought against it and other cigarette manufacturers by 46  U.S. states, the company agreed to participate in paying more than $200  billion to the states for smoking-related health-care costs.</p><p>altruism Ethical theory that regards the good of others as the end of  moral action; by extension, the disposition to take the good of others as  an end in itself. The term (French, altruisme, derived from Latin alter:  �other�) was coined in the 19th century by Auguste Comte and adopted  generally as a convenient antithesis to egoism. Most altruists have held  that each person has an obligation to further the pleasures and alleviate  the pains of other people. The same argument holds if happiness, rather  than pleasure, is taken as the end of life.</p><p>alum \'a-lom\ Inorganic compound, any of a class of hydrated double  salts, usually consisting of aluminum sulfate, water of hydration (an essen�  tial part of the crystal makeup), and the sulfate of another element. The  most important alums are those of potassium sulfate (potassium alum, or  potash alum, ^SO^Al^SO^^T^O), ammonium sulfate, and sodium  sulfate. Alums occur naturally in various minerals and can be prepared  and purified by crystallization from their solutions. Most are white crys�  tals with an astringent, acid taste. They are used as paper-sizing agents,  flocculating agents in water treatment, mordants in dyeing, and in pick�  les, baking powder, fire extinguishers, and medicines.</p><p>aluminum Metallic chemical element, chemical symbol Al, atomic num�  ber 13. A lightweight, silvery white metal, it is so reactive chemically that  it always occurs in compounds. It is the most abundant metallic element  in Earth�s crust, chiefly in bauxite (its principal ore), feldspars, micas, clay  minerals, and laterite. It also occurs in gemstones, such as topaz, garnet,  and chrysoberyl; emery, corundum, ruby, and sapphire are crystalline alumi�  num oxide. Aluminum was first isolated in 1825, became commercially  available in the late 19th century, and is now the most widely used metal  after iron. Its surface oxidizes at once to a hard, tough film, deterring fur�  ther corrosion. Uses include building and construction, corrosion-resistant  chemical equipment, auto and aircraft parts, power transmission lines,  photoengraving plates, cookware and other consumer goods, and tubes  for ointments and pastes. Important compounds include alums; alumina  (aluminum oxide), useful as corundum and as a carrier for many cata�  lysts; aluminum chloride, a widely used catalyst for organic syntheses;  and aluminum hydroxide, used to waterproof fabrics.</p><p>Alvarado \,al-va-'ra-tho\, Pedro de (b. c. 1485, Badajoz, Castile�d.  1541, in or near Guadalajara, New Spain) Spanish soldier and colonial  administrator.

It  occurs in middle to late adult life, destroying neurons and connections in  the cerebral cortex and resulting in significant loss of brain mass. The most  common form of dementia, Alzheimer disease progresses from short-term  memory impairment to further memory loss; deterioration of language,  perceptual, and motor skills; mood instability; and, in advanced stages,  unresponsiveness, with loss of mobility and control of body functions;  death typically ensues in 5-10 years. Originally described in 1906 by the  German neuropathologist Alois Alzheimer (1864-1915) with reference to  a 55-year-old person and regarded as a presenile dementia, Alzheimer  disease is now recognized as accounting for much of the senile dementia  once thought normal with aging. The 10% of cases that begin before age  60 result from an inherited mutation. Neuritic plaques and neurofibrillary  tangles in the brain on autopsy are the primary features used for diagno�  sis. No cure has been found. Most treatment targets the depression, behav�  ioral problems, and sleeplessness that often accompany the disease.</p><p>AM in full amplitude modulation Variation of the amplitude of a  carrier wave (commonly a radio wave) in correspondence to fluctuations  in the audio or video signal being transmitted. AM is the oldest method  of broadcasting radio programs. Commercial AM stations operate in the  frequency range of 535 to 1605 kHz. Because radio waves of these fre�  quencies are reflected back to the Earth�s surface by the ionosphere, they  can be detected by receivers hundreds of miles away. In addition to com�  mercial radio broadcasting, AM is also employed in short-wave radio  broadcasts, and in transmitting the video portion of television programs.

His early works, including The Violent Land (1942), explore the  exploitation and suffering of plantation workers. Despite imprisonment  and exile for leftist activities, he continued to produce novels, many of</p><p>which have been banned in Brazil and Portugal. Later works such as  Gabriela, Clove and Cinnamon (1958), Dona Flor and Her Two Hus�  bands (1966), and The War of the Saints (1993) preserve Amado�s politi�  cal attitude in their more subtle satire; many of his books were adapted  for film and television.</p><p>Amalfi \a-'mal-fe\ Town (pop., 2000: commune, 5,527), southern Italy,  on the Gulf of Salerno. It was of little importance until the mid-6th cen�  tury, when it fell under Byzantine control. It grew into one of the first  Italian maritime republics in the 9th century, becoming a rival of Venice  and Genoa. Annexed by Roger II of Sicily in 1131, it was sacked by Pisa  in 1135 and 1137 and rapidly declined in importance, though its maritime  code, the Tavola Amalfitana, was recognized in the Mediterranean until  1570.

Those with a very  high mercury content are liquid; others are crystalline. Amalgams of sil�  ver and tin, with minor amounts of copper and zinc, are used in dentistry  to fill teeth. Sodium amalgam is used in manufacturing chlorine and  sodium hydroxide by electrolysis of brine. Amalgams are used to recover  silver and gold from their ores: The ore is shaken with mercury, the amal�  gam is separated and heated until the mercury distills off (see distillation),  and the precious metal is the residue. Amalgams are also used to silver  mirrors and apply other metal coatings.</p><p>Amalric Va-'mal-rik, 'am-3l-rik\ I (b. 1136�d. July 11, 1174) King of  Jerusalem (1163-74). Amalric was a strong ruler who helped break the  unity of Muslims surrounding the Holy Land. He passed a law giving vas�  sals the right to appeal to the High Court against unjust treatment by their  lords. His invasion of Egypt (1163) led to a war with Nureddin of Syria,  which Amalric lost despite help from Manuel I Comnenus.

It flourished there from about the  2nd century bc to the end of the 3rd century ad, during the rule of the  Satavahana dynasty. Carved in relief on greenish-white limestone, these  sculptures depict events in the life of the Buddha. The compositions are  dynamic, sensuous, and dramatic, with overlapping figures and diagonals  suggesting depth. The style spread from the Amaravati ruins west to  Maharashtra Pradesh, to Sri Lanka (Ceylon), and to much of South Asia.  The Amaravati stupa was one of the largest in Buddhist India; it was  largely destroyed in the 19th century by building contractors to make lime  mortar.</p><p>Amarillo City (pop., 2000: 173,627), northern Texas, U.S. The chief  city of the Texas Panhandle, it originated in 1887 with the coming of the  railroad.

The two produced children together, but Sus�  anoo began to behave rudely and destructively, and Amaterasu withdrew  in protest into a cave, plunging the world into darkness. She was lured  out by the other gods and goddesses, and a rope was placed over its  entrance to prevent her return. Her chief place of worship is the Grand  Shrine of Ise, Shinto�s most important shrine.</p><p>Amati family Family of Italian violin makers in Cremona in the 16th  and 17th centuries. Andrea (c. 1520-c. 1578) set the form of the modem  violin. His two sons Antonio (c. 1550-1638) and Girolamo (1561-1630)  worked together and were known as the brothers Amati. Girolamo�s son  Nicolo (1596-1684), who like his forebears worked in Cremona, is  regarded as the family�s finest craftsman. Among his famous pupils were  Andrea Guarneri and Antonio Stradivari; Nicolo was succeeded by his son  Girolamo (1649-1740). The great contribution of the Amatis to the devel�  opment of the violin was their evolution of the flat, shallow model, which,  as improved by Stradivari, is capable of producing a brilliant soprano tone.</p><p>Amazon In Greek mythology, a member of a race of women warriors.  One of the labours of Heracles was to obtain the girdle of the Amazon  queen Hippolyte. In another tale, Theseus attacked the Amazons, and they  responded by invading Attica, where they were defeated; Theseus mar�  ried the Amazon Antiope. In ancient Greek art, Amazons resembled Ath�  ena (with weapons and helmet) and later Artemis (in a thin dress girded  high for speed).</p><p>Amazon River Portuguese Rio Amazonas River, northern South  America. It is the largest river in the world in volume and area of drain�  age basin; only the Nile River of eastern and northeastern Africa exceeds  it in length. It originates within 100 mi (160 km) of the Pacific Ocean in</p><p>the Peruvian Andes Mountains and flows some 4,000 mi (6,400 km) across  northern Brazil into the Atlantic Ocean. Its Peruvian length is called the  Maranon River; the stretch of river from the Brazilian border to the mouth  of the Negro River is the Solimoes River. Its more than 1,000 known  tributaries rise in the Guiana Highlands, the Brazilian Highlands, and  (principally) the Andes; 7 of these are longer than 1,000 mi (1,600 km),  and the Madeira River exceeds 2,000 mi (3,200 km). The Amazon can  accommodate large freighters as far upriver as the city of Manaus, Braz.,  1,000 mi (1,600 km) from the Atlantic. The first European descent was  made by Francisco de Orellana in 1541-42; he is said to have given the  river its name after reporting battles with tribes of women, whom he lik�  ened to the Amazons of Greek legend. Pedro Teixeira achieved the first  ascent in 1637-38, but the river remained little explored until the mid-  19th century. Many indigenous peoples originally lived along the river,  but they moved inland as exploring parties and raiders (see bandeira )  sought to enslave them. The river was opened to world shipping in the  mid-19th century; traffic increased exponentially with the coming of the  rubber trade, which reached its height c. 1910 but soon declined. Its basin  encompasses the world�s most extensive rainforest and is home to an  extraordinary diversity of birds, mammals, and other wildlife. Since the  1960s the effects of economic exploitation on the region�s ecology and  the destruction of the rainforest have generated worldwide concern.</p><p>Amazonia National Park Park, north-central Brazil, about halfway  between the cities of Manaus and Belem, along the Tapajos River.

In 1793 the  Qing emperor Qianlong changed the procedure for selecting the Dalai  Lama, and the Tibetans had to persuade the amban that they had complied.  In 1904, when the British were trying to force Tibet to sign a trade treaty,  the amban said he was powerless to negotiate for the Tibetans, an admis�  sion that called into question the degree of control China exercised over  Tibet. The ambans � role and authority continues to be debated by the Chi�  nese government and advocates of Tibetan independence in the attempt  to support their conflicting claims for Tibet�s status.</p><p>ambassador Highest-ranking diplomatic representative of one gov�  ernment to another or to an international organization. As formally defined  and recognized at the Congress of Vienna (1815), ambassadors were origi�  nally regarded as personal representatives of their country�s chief execu�  tive rather than of the whole country, and their rank entitled them to meet  personally with the head of state of the host country. Originally, only the  principal monarchies exchanged ambassadors; the U.S. did not appoint  ambassadors until 1893. Since 1945 all nations have been recognized as  equals, and ambassadors or their equivalents are sent to all countries with  which diplomatic relations are maintained. Before the development of  modern communications, ambassadors were entrusted with extensive  powers; they have since been reduced to spokespeople for their foreign  offices.</p><p>amber Fossil tree resin that occurs as irregular nodules, rods, or drop�  like shapes in all shades of yellow with nuances of orange, brown, and,  rarely, red. Milky-white opaque varieties are called bone amber. Hundreds  of species of insects and plants are found as fossils in amber. Deeply  coloured translucent to transparent amber is prized as gem material, and  numerous ornamental carved objects and beads are made from amber.  Amber has been found throughout the world, but the largest deposits occur  along the shores of the Baltic Sea.</p><p>ambergris Vam-bor-.gris, , am-b3r-,gre\ Waxy substance (about 80%  cholesterol) formed in the intestine of sperm whales, used chiefly as a spice  in the East and for fixing the scent of fine perfumes in the West.

Located in the  Malay Archipelago, it is 31 mi (50 km) long and 10 mi (16 km) wide, with  an area of 294 sq mi (761 sq km). Its chief port is also called Ambon  (pop., 2000: 205,664). The island is subject to earthquakes and volcanic  activity; Mount Salhatu (3,405 ft [1,038 m]) is its highest point. The clove  trade first attracted the Portuguese, who founded a settlement in 1521.  The Dutch ousted the Portuguese in 1605, took over the spice trade, and  in 1623 killed English settlers in the Amboina Massacre. The British cap�  tured Ambon in 1796 and 1810, but it was restored to the Dutch in 1814.  The Japanese occupied it during World War II. Retaken by the Dutch in  1945, it became part of Indonesia in 1949.

Cofounded in 1833 by William Lloyd Garrison and  Arthur Tappan, it promoted the formation of state and local auxiliaries to  agitate for abolition. Despite violent opposition, by 1840 the group had  2,000 auxiliaries and more than 150,000 members, including Theodore  Weld and Wendell Phillips. Its most effective public meetings featured tes�  timony by former slaves, including Frederick Douglass and William Wells  Brown. In 1839 it split into two factions: a radical group led by Garrison  that denounced the Constitution as supportive of slavery and a moderate  faction led by Tappan that led to the birth of the Liberty Party.</p><p>American Association of Retired Persons See AARP</p><p>American Ballet Theatre Prominent ballet company based in New  York City. It was founded in 1939 as the Ballet Theatre (the name was  changed in 1958) by Lucia Chase and Richard Pleasant to promote works  �American in character.� Oliver Smith replaced Pleasant as codirector in  1945; Mikhail Baryshnikov served as artistic director from 1980 to 1989  after dancing with the company in the 1970s. New ballets were created  for the company by Agnes de Mille, Jerome Robbins, Twyla Tharp, and Ant�  ony Tudor; Michel Fokine revived many of his earlier works for them as  well.

From its founding it has initiated test cases and  intervened in cases already in the courts. It may provide legal counsel, or  it may file an amicus curiae brief. The Scopes trial was one of its test cases;  it provided counsel for the Sacco-Vanzetti case. In the 1950s and �60s it  opposed the blacklisting of supposed left-wing subversives and worked  to guarantee freedom of worship and the rights of the accused. Its work  is performed by volunteers and full-time staff, including lawyers who  provide free legal counsel.

It arose out of disputes  over the issues of slavery, trade and tariffs, and the doctrine of states�  rights. In the 1840s and �50s, Northern opposition to slavery in the West�  ern territories caused the Southern states to fear that existing slavehold-  ings, which formed the economic base of the South, were also in danger.  By the 1850s abolitionism was growing in the North, and when the anti�  slavery Republican candidate Abraham Lincoln was elected president in  1860, the Southern states seceded to protect what they saw as their right  to keep slaves. They were organized as the Confederate States of America  under Jefferson Davis. The Northern states of the federal Union, under  Lincoln, commanded more than twice the population of the Confederacy  and held greater advantages in manufacturing and transportation capac�  ity. The war began in Charleston, S.C., when Confederate artillery fired  on Fort Sumter on April 12, 1861. Both sides quickly raised armies. In  July 1861, 30,000 Union troops marched toward the Confederate capital  at Richmond, Va., but were stopped by Confederate forces in the Battle  of Bull Run and forced to retreat to Washington, D.C. The defeat shocked  the Union, which called for 500,000 more recruits. The war�s first major  campaign began in February 1862, when Union troops under Ulysses S.  Grant captured Confederate forts in western Tennessee. Union victories  at the battles of Shiloh and New Orleans followed. In the East, Robert E.  Lee won several Confederate victories in the Seven Days' Battles and, after  defeat at the Battle of Antietam, in the Battle of Fredericksburg (December  1862). After the Confederate victory at the Battle of Chancellorsville, Lee  invaded the North and engaged Union forces under George Meade at the  momentous Battle of Gettysburg. The war�s turning point in the West  occurred in July 1863 with Grant�s success in the Vicksburg Campaign,  which brought the entire Mississippi River under Union control. Grant�s  command was expanded after the Union defeat at the Battle of Chicka-</p><p>mauga, and in March 1864 Lincoln gave him supreme command of the  Union armies. He began a strategy of attrition and, despite heavy Union  casualties at the battles of the Wilderness and Spotsylvania, began to sur�  round Lee�s troops in Petersburg, Va. (see Petersburg Campaign). Mean�  while William T. Sherman captured Atlanta in September (see Atlanta  Campaign), set out on a destructive march through Georgia, and soon cap�  tured Savannah. Grant captured Richmond on April 3, 1865, and accepted  Lee�s surrender on April 9 at Appomattox Court House. On April 26 Sher�  man received the surrender of Joseph Johnston, thereby ending the war.  The mortality rates of the war were staggering�there were about 620,000  deaths out of a total of 2.4 million soldiers. The South was devastated.  But the Union was preserved, and slavery was abolished.</p><p>American Express Co, U.S. credit card and travel services company.  Founded in 1850 as an express-transportation company, American  Express originally provided rapid transport of goods across New York and  the Midwest. The company introduced traveler�s checks in 1891 and  opened its first European office in Paris in 1895. Its contemporary busi�  nesses include credit cards and payment-processing systems, international  banking, and services for travelers (including trip planning, tour packages,  and business travel management).</p><p>American Federation of Labor-Congress of Industrial  Organizations See AFL-CIO</p><p>American Fur Co.

By 1834, when Astor sold his  company, it had become the largest commercial organization in the U.S.</p><p>American Indian or Native American or Amerindian Any</p><p>member of the various aboriginal peoples of the Western Hemisphere,  with the exception of the Eskimos (Inuit) and the Aleuts. Though the term  Native American is today often preferred over American Indian, particu�  larly in the U.S., many Native American peoples continue to prefer Ameri�  can Indian (or Indian). In Canada the name First Nation is preferred. The  ancestors of the American Indians were nomadic hunters of northeast Asia  who migrated over the Bering Strait land bridge into North America prob�  ably during the last glacial period (20,000-30,000 years ago). By c.  10,000 bc they had occupied much of North, Central, and South America.

They display an extraordinary structural range, and no  attempt to unite them into a small number of genetic groupings has won  general acceptance. Before the arrival of Columbus, more than 300 dis�  tinct languages were spoken in North America north of Mexico by an  estimated population of two to seven million. Today fewer than 170 lan�  guages are spoken, of which the great majority are spoken fluently only  by older adults. A few widespread language families (Algonquian, Iro-  quoian, Siouan, Muskogean, Athabaskan, Uto-Aztecan, Salishan) account  for many of the languages of eastern and interior North America, though  the far west was an area of extreme diversity (see Hokan; Penutian). It is  estimated that in Mexico and northern Central America (Mesoamerica),  an estimated 15-20 million people spoke more than 300 languages before  Columbus. The large Otomanguean and Maya families and a single lan�  guage, Nahuatl, shared Mesoamerica with many smaller families and lan�  guage isolates. More than 10 of these languages and language complexes  still have more than 100,000 speakers. South America and the West Indies  had an estimated pre-Columbian population of 10-20 million, speaking  more than 500 languages. Important language families include Chibchan  in Colombia and southern Central America, Quechuan and Aymaran in  the Andean region, and Arawakan, Cariban, and Tupian in northern and  central lowland South America. Aside from Quechuan and Aymaran, with  about 10 million speakers, and the Tupian language Guarani, most remain�  ing South American Indian languages have very few speakers, and some  face certain extinction.</p><p>American Indian Movement (AIM) Civil rights organization  founded in 1968, originally to help urban American Indians displaced by</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>American Indian religions &#x25BA; American Revolution I 59</p><p>government programs. It later broadened its efforts to include demands  for economic independence, autonomy over tribal areas, restoration of  illegally seized lands, and protection of Indian legal rights and traditional  culture. Some of its protest activities involved violence and were highly  publicized (see Wounded Knee). Internal strife and the imprisonment of  some leaders led to the disbanding of its national leadership in 1978,  though local groups have continued to function.</p><p>American Indian religions. North Religious beliefs and practices  of the indigenous peoples of North America. They are characterized by a  conviction that spirit moves through all things, animate and inanimate,  and that the living are intimately connected with the souls of the dead.  They discover recognizable beings in the natural world of animals, plants,  and trees, as well as in natural features such as mountains, lakes, and  clouds. Because North American religions were so highly localized, it is  impossible to determine how many have existed, and their beliefs have  varied widely. Whereas Iroquois elders speak of a perfectly wise and good  Creator who planned the universe, the Koyukon envision the creator as  Raven, a trickster god who is only one of many powerful spirits. Whereas  nearly all Navajo ceremonies are performed on behalf of individuals in  response to specific needs, most Pueblo ceremonies are performed com�  munally and scheduled according to the cycles of nature. However, all  native North American religions share certain features: ancestral lands and  locally sacred spots are important; access to some knowledge is restricted,  and initiation is required to acquire it; kinship obligations are central; the  oral tradition includes narratives that record human interaction with non�  human powers; and generosity is a religious act. Contact with Europeans  led to development of new religious movements, including the Ghost  Dance tradition and the Native American Church. See also Mesoamerican  religions.</p><p>American Indian religions. South Religious beliefs and practices  of the indigenous peoples of South America. The ancient Andean civiliza�  tions of the Chimu and the Inca had highly developed religions. The Inca  religion combined complex ceremonies, animistic beliefs, belief in objects  having magical powers, nature worship, and sun worship. The Incas built  monumental temples, occupied by priests and Chosen Women. Priests  conducted divination, and sacrifices were offered on every important occa�  sion. Human sacrifice was offered when the need was extreme. In present-  day South America, as many as 1,500 distinct native cultures have been  described, and religious beliefs vary greatly. Creation mythologies are of  major importance, often describing the origin of the first world and its  fate as well as the creation and destruction of subsequent worlds. Cer�  emonial initiation into adulthood is widely practiced, both for males and  females, with the initiation ceremony often acting out events from the  dawn of creation. Initiations are also used to mark the ascent of individu�  als into positions of religious authority, with priests, diviners, and spirit  mediums playing special roles. The shaman specializes in inducing states  of ecstasy, controlling the passage of the soul out of and back into the  body. Ritual fires, musical instruments (especially the rattle), esoteric lan�  guages, and sacred songs may be used in a theatrical performance  designed to demonstrate the shaman�s command of invisible powers.  Christianity has come to be a strong component of folk belief among many  native peoples, but it continues to be interpreted in the light of local tra�  dition, and elements of traditional religion continue to survive.

It was founded by the labour leaders Sidney Hillman and  David Dubinsky and by liberal Democrats and old-line socialists. The party  supported Franklin D. Roosevelt�s New Deal programs and backed candi�  dates who endorsed liberal social legislation. Though influential in New  York City elections, after 1940 it was plagued by divisions between pro-  and anti-communist factions. It was dissolved in 1956.</p><p>American League (AL) One of the two associations of professional  baseball teams in the U.S. and Canada designated as major leagues; the  other is the National League (NL). The AL was founded in 1900, and,  beginning in 1903, the champions of the AL and NL have engaged in an  annual World Series competition. There are now three divisions in the AL:  Eastern (comprising the Baltimore Orioles, Boston Red Sox, New York  Yankees, Tampa Bay Devil Rays, and Toronto Blue Jays), Central (Chi�  cago White Sox, Cleveland Indians, Detroit Tigers, Kansas City Royals,  and Minnesota Twins), and Western (Los Angeles Angels of Anaheim,  Oakland Athletics, Seattle Mariners, and Texas Rangers).</p><p>American Legion Organization of U.S. war veterans. Founded in  1919, it works for the care of disabled and sick veterans and promotes  compensation and pensions for the disabled, widows, and orphans. Non�  political and nonsectarian, its membership requirement is honourable ser�  vice and an honourable discharge. It was instrumental in establishing  veterans� hospitals, and it sponsored the creation of the U.S. Veterans  Administration in 1930. In 1944 it played an important role in the pas�  sage of the Gl Bill. The American Legion claims about three million mem�  bers in some 15,000 local posts, or groups.</p><p>American Medical Association (AMA) Organization of U.S. phy�  sicians. It was founded in 1847 �to promote the science and art of medi�  cine and the betterment of public health.� It has about 250,000 members,  about half of all practicing U.S. physicians. It disseminates information  to its members and the public, operates as a lobbying group, and helps  set medical education standards. Its publications include Journal of the  American Medical Association, American Medical News, and journals on  medical specialties.</p><p>American Motors Corp.

(successor to Nash Motor Co.,  founded 1916) and Hudson Motor Car Co. (founded 1909). AMC pro�  duced AMC compact cars, AM General trucks and buses, and, until 1968,  Kelvinator appliances. Jeeps joined the product line after AMC purchased  the Kaiser-Jeep Corp. (dating to 1903) in 1970. AMC became a subsid�  iary of Chrysler Corp. in 1987, which in turn merged with Daimler-Benz  in 1998 to form DaimlerChrysler AG.</p><p>American Museum of Natural History Major centre of research  and education on the natural sciences, established in New York City in  1869. It pioneered in staging field expeditions and creating dioramas and  other lifelike exhibits showing natural habitats and their plant and animal  life. Its research collections contain tens of millions of specimens, and its  fossil and insect collections are among the largest in the world. It con�  ducts research in anthropology, astronomy, entomology, herpetology, ich�  thyology, invertebrate biology, mammalogy, mineralogy, ornithology, and  vertebrate paleontology, and it maintains permanent research stations in  The Bahamas and the U.S. states of New York, Florida, and Arizona. It  also contains one of the world�s largest planetariums.</p><p>American Parly See Know-Nothing Party</p><p>American Protective Association (APA) Secret anti-Catholic,  anti-immigrant society formed in Iowa in 1887. Its membership, consist�  ing mainly of farmers who feared the growth and political power of  immigrant-populated cities, rose to more than two million in the 1890s.  Membership dwindled after the election of 1896 and the return of agri�  cultural prosperity in the Midwest. By 1911 the society had disappeared.</p><p>American Renaissance or New England Renaissance Period  from the 1830s roughly until the end of the American Civil War in which  U.S. literature came of age as an expression of a national spirit. The lit�  erary scene was dominated by New England Brahmin writers, notably  Henry Wadsworth Longfellow, Oliver Wendell Holmes, and James Russell  Lowell. Also influential were the Transcendentalists (see Transcendental�  ism), including Ralph Waldo Emerson and Henry David Thoreau, as well  as the great imaginative writers Nathaniel Hawthorne, Herman Melville,  Walt Whitman, and Edgar Allan Poe.</p><p>American Revolution or United States War of Indepen�  dence (1775 -83) War that won political independence for 13 of Brit�  ain�s North American colonies, which formed the United States of  America. After the end of the costly French and Indian War (1763), Brit�  ain imposed new taxes (see Stamp Act; Sugar Act) and trade restrictions  on the colonies, fueling growing resentment and strengthening the colo�  nists� objection to their lack of representation in the British Parliament.  Determined to achieve independence, the colonies formed the Continen�  tal Army, composed chiefly of minutemen, to challenge Britain�s large,  organized militia. The war began when Britain sent a force to destroy rebel  military stores at Concord, Mass. After fighting broke out on April 19,  1775 (see Battles of Lexington and Concord), rebel forces began a siege  of Boston that ended when American forces under Henry Knox forced out  the British troops under William Howe on March 17, 1776 (see Battle of  Bunker Hill). Britain�s offer of pardon in exchange for surrender was  refused by the Americans, who declared themselves independent on July  4, 1776 (see Declaration of Independence). British forces retaliated by driv-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>60 I American Saddlebred &#x25BA; Amhara</p><p>ing the army of George Washington from New York to New Jersey. On  December 25, Washington crossed the Delaware River and won the battles  of Trenton and Princeton. The British army split to cover more territory,  a fatal error. In engaging the Americans in Pennsylvania, notably in the  Battle of the Brandywine, they left the troops in the north vulnerable.  Despite a victory in the Battle of Ticonderoga, British troops under John  Burgoyne were defeated by Horatio Gates and Benedict Arnold in the Battle  of Saratoga (Oct. 17, 1777). Washington quartered his 11,000 troops  through a bleak winter at Valley Forge, where they received training from  Frederick Steuben that gave them victory in Monmouth, N.J., on June 28,  1778. British forces in the north thenceforth chiefly concentrated near  New York. France, which had been secretly furnishing aid to the Ameri�  cans since 1776, finally declared war on Britain in June 1778. French  troops assisted American troops in the south, culminating in the success�  ful Siege of Yorktown, where Charles Cornwallis surrendered his forces  on Oct. 19, 1781, bringing an end to the war on land. War continued at  sea, fought chiefly between Britain and the U.S.�s European allies. The  navies of Spain and the Netherlands contained most of Britain�s navy near  Europe and away from the fighting in America. The last battle of the war  was won by the American navy under John Barry in March 1783 in the  Straits of Florida. With the Treaty of Paris (Sept. 3, 1783), Britain rec�  ognized the independence of the U.S. east of the Mississippi River and  ceded Florida to Spain.</p><p>American Saddlebred or American Saddle Horse Breed of  light horse that originated in the U.S. The breed was developed by cross�  ing Thoroughbreds, Morgans, and Standardbreds on native mares having  an easy gait. It stands 15-16 hands (5-5.3 ft [1.5-1.6 m]) high, and its  colours are bay, brown, black, gray, and chestnut. Two show categories  are for three-gaited and five-gaited horses. The three natural gaits are  walk, trot, and canter; the five-gaited horse also has two trained gaits, the  rack and the slow gait, or running walk. The American Saddlebred is also  well known as a fine harness horse for show.</p><p>American Samoa officially Territory of American Samoa</p><p>Unincorporated U.S. territory (pop., 2000: 57,291), southwest-central  Pacific Ocean. It includes the islands of Tutuila (the largest, with over  two-thirds of the territory�s land area and almost all of the population),  Aunuu, Rose, Swains, and the Manua group. Area: 77 sq mi (199 sq km).  Capital: Fagatogo (Pago Pago; on Tutuila). Languages: Samoan, English  (both official). Religion: Christianity (mostly Protestant; also Roman  Catholic, other Christians). Currency: U.S. dollar. Most of the islands are  rocky, formed from extinct volcanoes, and are surrounded by coral reefs.  Tutuila and the islands of Manua are dominated by central mountain  ranges. Fishing and tourism are major industries, but the U.S. adminis�  tration is the main employer. The majority of the population is of Samoan  ancestry. The islands were probably inhabited by Polynesians 3,000 years  ago. Dutch explorers became the first Europeans to visit the islands in  1722. Missionaries began arriving in the islands in the 1830s. The U.S.  gained the right to establish a naval station at Pago Pago in 1878, and the  U.S., Britain, and Germany administered a tripartite protectorate in 1889�  99. The high chiefs ceded the eastern islands to the U.S. in 1904. Ameri�  can Samoa was administered by the U.S. Department of the Navy until  1951 and afterward by the Department of the Interior. Its current consti�  tution was approved in 1967, and in 1978 the territory�s first elected gov�  ernor took office.</p><p>American Stock Exchange (AMEX) Stock exchange in the U.S.  Originally known as �the Curb,� it began as an outdoor marketplace in  New York City c. 1850. It moved indoors to its present location in the  Wall Street area in 1921. Once a marketplace for securities not reputable  enough for the New York Stock Exchange, it became equally respectable,  with its own listing admissions requirements. In 1998 it merged with the  National Association of Securities Dealers (NASD), then-owner of the  NASDAQ exchange, to form the Nasdaq-Amex Market Group. After  NASD sold its interest in the NASDAQ in 2000, AMEX remained a  NASD subsidiary.</p><p>American System of manufacture Production of many identical  parts and their assembly into finished products. Though Eli Whitney has  been credited with this development, the ideas had appeared earlier in  Europe and were being practiced in arms factories in the U.S. (see armoury  practice). Marc Brunel, while working for the British Admiralty (1802-08),  devised a process for producing wooden pulley blocks by sequential  machine operations, whereby 10 men (rather than the 110 needed previ�  ously) could make 160,000 pulley blocks per year. Not until London�s</p><p>Crystal Palace exhibition (1851) did British engineers, viewing exhibits of  machines used in the U.S. to produce interchangeable parts, begin to apply  the system.

Supporting the  creation of a strong central government, Ames argued for ratification of  the new U.S. Constitution at the Massachusetts constitutional convention.  He became known for his uncompromising advocacy of the rights of  property and his protective attitude toward commercial interests, which  he defended in trenchant writing and commanding speech. In 1788 he  defeated Samuel Adams for a seat in the first session of the U.S. House of  Representatives; he was reelected three times.

Jan. 29, 1717, Sev-  enoaks, Kent, Eng.�d. Aug. 3, 1797, Sevenoaks) British army com�  mander. In the French and Indian War, he took the French fort at  Louisbourg, Cape Breton Island, in 1758 and was promoted to chief of  command in America. In 1760 he directed the campaign that captured  Quebec and Montreal, and in 1761 he quelled the Indian uprising under  Pontiac. Having secured Canada for Britain, he remained there as  governor-general until 1763. Returning to England, he served as com�  mander in chief of the British army (1772-95), but his tenure was marred  by failure in the war with the American colonies and by serious abuses  in the army. He was created a baron in 1776 and a field marshal in 1796.  Several U.S. towns and Amherst College are named for him.</p><p>Amherst Vam-orstV College Private liberal arts college in Amherst,  Massachusetts, U.S., chartered in 1825. Noah Webster was one of its  founders. Consistently ranked as one of the finest colleges in the U.S., it  offers a wide range of courses in the humanities, social sciences, and  natural sciences. Originally a men�s college, it became coeducational in  1975. It participates in an exchange program with nearby Hampshire,  Mount Holyoke, and Smith colleges and the University of Massachusetts.</p><p>amicus curiae Vo-'me-kos-'kyiir-e-I, o-'ml-kos-'kyur-e-eV (Latin:  �friend of the court�) One who assists a court by furnishing information  or advice regarding questions of law or fact. A person (or other entity,  such as a state government) who is not a party to a particular lawsuit but  nevertheless has a strong interest in it may be allowed, by leave of the  court, to file an amicus curiae brief, a statement of particular views on the  subject matter of the lawsuit. Such briefs are often filed in cases involv�  ing public-interest matters (e.g., entitlement programs, consumer protec�  tion, civil rights).</p><p>Amida See Amitabha</p></section><section><p>amide \'a-,mld\ Any member of either of two classes of nitrogen-  containing organic compounds related to ammonia and amines and contain�  ing a carbonyl group (�C=0; see functional group). The first class,  covalent amides are formed by replacing the hydroxyl group (�OH) of  an acid with an amino group (�NR 2 , in which R may represent a hydro�  gen atom or an organic combining group, such as methyl). Amides formed  from carboxylic acids, called carboxamides, are solids except for the sim�  plest, formamide, a liquid. They do  not conduct electricity, have high  boiling points, and (when liquid) are  good solvents. There are no practical  natural sources of simple covalent  amides, but the peptides and proteins in  living systems are long chains (poly�  mers) with peptide bonds (see cova�  lent bond), which are amide linkages.  Urea is an amide with two amino  groups. Commercially important  covalent amides include several used  as solvents; others are the sulfa drugs  and nylon. The second class, ionic  (salt-like) amides (see ionic bond),  are made by treating a covalent  amide, an amine, or ammonia with a  reactive metal (e.g., sodium) and are  strongly alkaline.</p><p>Amiens \am-'ye n \ ancient Samarobriva later Ambianum City  (pop., 1999: 135,801), northern France. Located on the Somme River, it  became a Roman stronghold. The chief city of a medieval county, it passed  to Burgundy in 1435 and was captured by the Spanish in 1597. Recovered  by Henry IV, it served as the capital of Picardy until 1790. The Prussians  captured the city in 1870, and the Germans held it briefly in 1914; it gave  its name to a successful Allied counteroffensive against Germany in 1918.  The Germans occupied it during World War II. It has been a major cen�  tre of the French textile industry since the 16th century and is the site of  the Gothic cathedral of Notre-Dame, the largest church in France.</p><p>Amiens \am-'ya n . Treaty of (March 27, 1802) Agreement signed at  Amiens, France, by Britain, France, Spain, and the Batavian Republic  (The Netherlands). By the treaty, France and its allies recovered most of  their colonies, despite their military reverses overseas. The treaty ignored  continuing trade differences between Britain and France, but it achieved  a peace in Europe for 14 months during the Napoleonic Wars.</p><p>Amin \a-'men\ (Dada Oumee), Idi (b. 1924/25, Koboko, Ugan.�d.  Aug. 16, 2003, Jiddah, Saud.Ar.)</p><p>Military officer and president (1971�</p><p>79) of Uganda. A member of the  small Kakwa ethnic group and a  Muslim, he was closely associated  during his military career with Mil-  ton Obote, Uganda�s first prime min�  ister and president. In 1971 he staged  a coup against Obote. He expelled all  Asians from Uganda in 1972,  reversed Uganda�s amicable rela�  tions with Israel, was personally  involved in the Palestinian hijacking  of a French airliner to Entebbe (see  Entebbe raid), and ordered the torture  and murder of 100,000-300,000  Ugandans. In 1978 he ordered an  attack on Tanzania, but Tanzanian troops, aided by Ugandan nationalists,  were able to overpower the invaders. As the Tanzanian-led forces neared  Kampala, Uganda�s capital, Amin fled to Libya and eventually settled in  Saudi Arabia.</p><p>amine \o-'men\ Any of a class of NiTROGEN-containing organic com�  pounds derived, either in principle or in practice, from ammonia (NH 3 ).  Almost all their chemical names end in -ine. Replacement of one, two,  or all three of the hydrogen atoms in ammonia with organic groups yields  primary, secondary, or tertiary amines, respectively. Addition of a fourth  hydrogen with an accompanying positive charge on the nitrogen atom  results in a quaternary amine. Naturally occurring amines include alka�  loids, present in certain plants; some neurotransmitters, including dopam�  ine and epinephrine; and histamine. Industrially important amines include  aniline, ethanolamine, and others, used in making rubber, dyes, pharma�  ceuticals, and synthetic resins and fibres and in a host of other applica�  tions. A nitrogen atom with one or two hydrogens is often referred to as  an amino group.</p><p>amino acid \3-'me-no\ Any of a class of organic compounds in which  a carbon atom has bonds to an amino group (�NH 2 ), a carboxyl group  (�COOH), a hydrogen atom (�H), and an organic side group (called  �R). They are therefore both carboxylic acids and amines. The physical  and chemical properties unique to each result from the properties of the  R group, particularly its tendency to interact with water and its charge (if  any). Amino acids joined linearly by peptide bonds (see covalent bond)  in a particular order make up peptides and proteins. Of over 100 natural  amino acids, each with a different R group, only 20 make up the proteins  of all living organisms. Humans can synthesize 10 of them (by intercon�  versions) from each other or from other molecules of intermediary metabo�  lism, but the other 10 (essential amino acids: arginine, histidine, isoleucine,</p><p>LEUCINE, LYSINE, METHIONINE, PHENYLALANINE, THREONINE, TRYPTOPHAN, and VALINE)  must be consumed in the diet.</p><p>Amis \'a-mis\, Martin (b. Aug. 25, 1949, Oxford, Oxfordshire, Eng.)  British writer and critic. The son of writer Kingsley Amis, he graduated  from Oxford University in 1971. He worked for the Times Literary  Supplement and the New Statesman before becoming a full-time writer.  His works�including the novels Money (1984), London Fields (1989),  and Night Train (1998) as well as the short-story collection Heavy Water</p><p>White-tipped amethyst from Guerrero,  Mexico</p><p>LEE BOLTIN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>62 I Amis &#x25BA; amniocentesis</p><p>(1999)� feature inventive word play and often scabrous humour as they  satirize the horrors of modem urban life. Amis also published an  acclaimed autobiography. Experience (2000), and an idiosyncratic volume  centred on Joseph Stalin, Koba the Dread (2002).</p><p>Amis, Sir Kingsley (William) (b. April 16, 1922, London, Eng.�d.  Oct. 22, 1995, London) British novelist, poet, critic, and teacher. His first  novel, Lucky Jim (1954; film, 1957), was a hugely successful comic mas�  terpiece. He was often characterized as an Angry Young Man, a label he  rejected. Notable among his more than 40 books (including four volumes  of poetry) are the mordantly humorous novels That Uncertain Feeling  (1955; film. Only Two Can Play , 1962), The Green Man (1959; film,  1957), Jake�s Thing (1978), and The Old Devils (1986, Booker Prize). He  was the father of Martin Amis.</p><p>Amish Ya-mish\ Member of a conservative Christian group in North  America known as the Old Order Amish Mennonite Church. The Amish  originated in 1693-97 as followers of the Mennonite elder Jakob Ammann  (1644?-c. 1730) in Switzerland, Alsace, and Germany. He taught that  lying was grounds for excommunication (which meant being shunned by  all other Mennonites), that clothing should be uniform and beards  untrimmed, and that the state church should be avoided. Migration to  North America and assimilation eliminated the Amish in Europe. They  settled in Pennsylvania in the 18th century. After 1850 they split into �Old  Order� (traditional) and �New Order� (now the Mennonite churches). Old  Order Amish now live in Pennsylvania, Ohio, Indiana, Iowa, Illinois, and  Kansas. Adults are baptized and admitted to formal church membership  at age 17 to 20. Services are in Pennsylvania Dutch (a German dialect)  and some English. Though similar in theology to Mennonites, Amish wear  modest, old-fashioned clothing and generally reject modern technology,  including automobiles and telephones.</p><p>Amistad mutiny (July 2, 1839) Slave rebellion aboard the schooner  Amistad. The revolt took place off the coast of Cuba when 53 Africans  who had been abducted from Sierra Leone for the slave trade, seized con�  trol of the ship, killed the captain and cook, and ordered the navigator to  sail for Africa. Pretending to do so, he sailed generally northward instead,  and the ship was intercepted two months later off New York. Despite  attempts by Pres. Martin Van Buren to send the Africans to Cuba, aboli�  tionists demanded a trial, contending the men were free under interna�  tional law. A federal judge agreed, and the government appealed to the  U.S. Supreme Court, where in 1841 defending counsel John Quincy Adams  successfully argued that the men should be freed. Donations helped the  35 survivors to return to Sierra Leone in 1842.</p><p>Amitabha \,am-i-'ta-b9\ Japanese Amida Saviour deity worshiped by  followers of Pure Land Buddhism in  Japan. According to the Sukhavati-  vyuha-sutra (Pure Land SUTRA), the  monk Dharmakara vowed many ages  ago that once he attained buddha-  hood, all who believed in him and  called upon his name would be born  into his paradise (the Pure Land) and  reside there until achieving nirvana.</p><p>The cult of Amitabha came to the  forefront in China c. 650 and then  spread to Japan, where it led to the  formation of the Pure Land and True  Pure Land sects. In Tibet and Nepal,</p><p>Amitabha is regarded as one of the  five eternal buddhas (rather than as a  saviour), who manifested himself as  the earthly Buddha Gautama and as  the BODHISATTVA AVALOKITESVARA.</p><p>Amman \a-'man\ City (pop., 2000  est.: 1,147,447), capital of Jordan. It lies 25 mi (40 km) northeast of the  Dead Sea. Amman is by far the largest city of Jordan. Fortified settlements  have existed in the area from remote antiquity; the earliest date from the  Chalcolithic Period (c. 4000-3000 bc). As Rabbah, it became the capital  of the Ammonites. It was conquered by Egypt�s Ptolemy II (Ptolemy Phil-  adelphus), who renamed it Philadelphia, a name it retained through  Roman times. Taken by the Arabs in ad 635, it later went into decline and  subsequently disappeared. In 1878 the Ottoman Empire resettled it. When  the British established the country of Transjordan in 1921, Amman</p><p>became its capital. Its modem development was furthered by the inde�  pendence of Transjordan in 1946. Along with the rest of Jordan (the  country�s name from 1949), Amman has had to absorb a large number of  Arab refugees that fled Palestine during the Arab-Israeli wars.</p><p>Ammannati \,am-an-'na-te\ / Bartolommeo or Bartolommeo  Ammanati (b. June 18, 1511, Settignano, near Florence�d. April 22,  1592, Florence ) Italian sculptor and architect active chiefly in Florence.  He trained under Baccio Bandinelli in Florence and Jacopo Sansovino in  Venice. In 1550 he went to Rome, where he collaborated with Giorgio  Vasari and Giacomo da Vignola on the Villa Giulia. In 1555 he returned  to Florence, where he spent the rest of his career working for the Medicis.  He finished the Laurentian Library, begun by Michelangelo, but is best  known for the Bridge of Santa Trinita and his additions to Filippo Brunelle�  schi�s Pitti Palace, including the courtyard. His buildings mark the tran�  sition from the Classicizing Renaissance to the more exuberant Baroque  style.</p><p>ammonia Vo-'mo-nysX Colourless, pungent gas composed of nitrogen  and hydrogen, chemical formula NH 3 . Easily liquefied by compression or  cooling for use in refrigerating and air-conditioning equipment, it is manu�  factured in huge quantities. Ammonia is made by the Haber-Bosch process  (see Fritz Haber). Its major use is as a fertilizer, applied directly to soil from  tanks of the liquefied gas. Also employed as fertilizers are salts of ammo�  nia, including ammonium phosphate and ammonium nitrate (the latter  used in high explosives as well). Ammonia has many other industrial uses  as a raw material, catalyst, and alkali. It dissolves readily in water to form  ammonium hydroxide, an alkaline solution (see base) familiar as a house�  hold cleaner.</p><p>ammonia-soda process See Solvay process</p><p>ammonoid Vam-o-.nokL Any of a group of extinct shelled cephalopods,  related to the modern pearly nautilus, that are commonly found as fossils  in marine rocks of the Devonian through Cretaceous periods (410-65 mil�  lion years ago). Most ammonoids were predators. The shells, either  straight or coiled, served as protective and supportive structures and  enabled the animals to compensate for varying water depths. Ammonoids  are important index fossils because of their wide geographic distribution  in shallow marine waters, rapid evolution, and easily recognizable fea�  tures. See also belemnoid.</p><p>amnesia \am-'ne-zh9\ Loss of memory as a result of brain injury or  deterioration, shock, fatigue, senility, drug use, alcoholism, anesthesia,  illness, or neurotic reaction. Amnesia may be anterograde (in which events  following the causative trauma or disease are forgotten) or retrograde (in  which events preceding the trauma or disease are forgotten). It can often  be traced to a severe emotional shock, in which case personal memories  (in effect, identity) rather than such abilities as language skills are affected.  Such amnesia seems to represent an escape from disturbing memories and  is thus an example of repression; these memories can generally be recov�  ered through psychotherapy or after the amnesic state has ended. Amnesia  may occasionally last for weeks, months, or even years, a condition  known as fugue.</p><p>amnesty In criminal law, a sovereign act of oblivion or forgetfulness  (from Greek amnestia, �forgetfulness�) granted by a government, espe�  cially to a group of persons who are guilty of (usually political) crimes  in the past. It is often conditional upon the group�s return to obedience  and duty within a prescribed period. See also pardon.</p><p>Amnesty International (Al) International human-rights organiza�  tion. It was founded in 1961 by Peter Benenson, a London lawyer who  organized a letter-writing campaign calling for amnesty for �prisoners of  conscience.� AI seeks to inform the public about violations of human  rights, especially abridgments of freedom of speech and religion and the  imprisonment and torture of political dissidents. It actively seeks the  release of political prisoners and support of their families when neces�  sary. Its members and supporters are said to number one million people  in some 140 countries. Its first director, Sean MacBride, won the 1974  Nobel Prize for Peace; AI itself won the award in 1977.</p><p>amniocentesis V.am-ne-o-sen-'te-sosN Surgical insertion of a hollow  needle through the abdominal wall into the uterus of a pregnant female  to extract fluid from the amniotic sac for analysis of fluid and fetal cells.

Some  amoebas are found on the bottom of  freshwater streams and ponds. Oth�  ers live in the human digestive sys�  tem; one type causes amebic  dysentery in humans. Each amoeba  contains a small mass of jellylike  cytoplasm with vacuoles and a  nucleus. Food is taken in and mate�  rial is excreted at any point on the  cell surface. Amoebas are used  extensively in cell research for deter�  mining the relative functions and interactions of the nucleus and the cyto�  plasm.</p><p>Amon \'a-,man\ or Amen Egyptian deity revered as king of the gods.  Amon may have originated as a local deity at Khmun in Middle Egypt.  His cult spread to Thebes, where he became patron of the pharaohs by  Mentuhotep I�s reign (2008-1957 bc) and was identified with the sun god  Re. Represented as a human, a ram, or both, Amon-Re was worshiped  with the goddess Mut and the youthful god Khons. Akhenaton directed  his reforms against the cult of Amon, but with little success, and Amon�s  status was restored in the 14th�13th century bc. In the New Kingdom,  Amon came to be seen as one of a triad with Ptah and Re, and in the  11th-10th century bc as a universal god who intervened in affairs of state  by speaking through oracles.</p><p>amortization V.am-or-ti-'za-shonV In finance, the systematic repayment  of a debt; in accounting, the systematic writing off of some account over  a period of years. An example of the first meaning is a home mortgage,  which may be repaid in monthly installments that include interest and a  gradual reduction of the principal. Such systematic reduction is safer for  the lender, since it is easier for the borrower to repay a series of small  amounts than a single lump sum. In the second sense, a firm may gradu�  ally reduce the balance-sheet valuation of a depreciable asset such as a  building, machine, or mine. The U.S. government has sometimes permit�  ted accelerated amortization of assets, which encourages industrial devel�  opment by decreasing a company�s tax burden in the years immediately  after a purchase.</p><p>Amos (fl. 8th century bc) Earliest Hebrew prophet (one of the 12 Minor  Prophets) to have a biblical book named for him. Born in Tekoa in Judah,  he was a shepherd. According to the book of Amos, he traveled to the  richer and more powerful northern kingdom of Israel to preach his visions  of divine destruction and the message that God�s absolute sovereignty  required justice for rich and poor alike and that God�s chosen people were  not exempt from the moral order. He foretold the destruction of the north�  ern kingdom and Judah and anticipated the predictions of doom by later  biblical prophets.</p><p>Amos ' n ' Andy See Freeman and Charles Correll Gosden</p><p>a mo site Va-ms-.sfiA Variety of the silicate mineral cummingtonite,  which is a source of asbestos.

Jan. 22, 1775, Lyon, France�d.  June 10, 1836, Marseille) French physicist, founder of the science of  electromagnetism. A prodigy who mastered the entire known field of  mathematics by age 12, he became a professor of physics, chemistry, and  mathematics. He formulated a law of electromagnetism, called Ampere's  law, that describes the magnetic force between two electric currents. An  instrument he devised to measure the flow of electricity was later refined  as the galvanometer. His chief published work was Memoir on the Math�  ematical Theory of Electrodynamic Phenomena (1827). The ampere (A)  unit of electric current was named for him.</p><p>Ampere's law Law of electromagnetism that describes mathematically  the magnetic force between two electric currents. It was named after A.-M.  Ampere, who discovered that such forces exist. If two currents flow in the  same direction, the force between the two wires is attractive; if they flow</p><p>in opposite directions, the force is repulsive. In each case, the force is  directly proportional to the currents.</p><p>amphetamine Vam-'fe-to-.menX Organic compound, prototype of a  class of synthetic amphetamine drugs (e.g., Benzedrine, Dexedrine, meth-  amphetamine), that stimulates the central nervous system. It was first syn�  thesized in 1887. Amphetamines cause wakefulness, euphoria, decreased  fatigue, and increased ability to concentrate. Since they dull the appetite,  they have been used for weight reduction. Often called �speed,� they are  used (often illicitly) to stay awake. In children with attention deficit  (hyperactivity) disorder, they have a calming effect, helping them con�  centrate. Undesirable effects include overstimulation, with paranoia, rest�  lessness, insomnia, tremor, and irritability, and a deep depression when the  drug wears off. This, along with rapid development of tolerance requir�  ing increased doses, can lead to drug addiction.</p><p>amphibian Any member of a class (Amphibia) of cold-blooded verte�  brate animals that includes more than 4,400 species in three groups: frogs  and toads (order Anura), salamanders (order Caudata), and caecilians (order  Apoda). Probably evolved from certain fish species of the Early Devonian  period (417-391 million years ago), amphibians were the first vertebrates  to move from an aquatic environment to land. Most species have an  aquatic larval, or tadpole, stage that metamorphoses into a terrestrial adult,  but a few species spend their entire life in water. Amphibians are found  worldwide, the majority in the tropics.</p><p>amphibious warfare Military operations directed against hostile  shores and characterized by attacks launched from the sea by naval and  landing forces. It has been conducted since ancient times. The Greeks  attacking Troy (1200 bc) had to make a shore landing, as did the Persian  invaders of Greece prior to the Battle of Marathon (490 bc). The British-  led landings at Gallipoli (1915) were the main amphibious assault in World  War I. The Allies of World War II found amphibious tactics essential in  the island-hopping Pacific campaign and in the famous D-Day of the  Normandy campaign, which still ranks as the greatest amphibious assault  in history. Amphibious warfare�s greatest advantage is its mobility and  flexibility; its greatest limitation is that the attacker must start from noth�  ing to build up strength ashore. Modern amphibious forces attempt to  overcome this by fielding larger and more efficient landing vessels and  also by using helicopters and short-takeoff and -landing airplanes to  deploy troops beyond the hostile shore.</p><p>amphibole Vam-fs-.boL Any of a group of common rock-forming  hydrous silicate minerals. Amphiboles occur in many igneous rocks as  minor and major constituents and form the major component in many  gneisses and schists. Some highly fibrous forms are collectively called  ASBESTOS.</p><p>amphibole asbestos Collective term for three highly fibrous  (asbestiform) varieties of amphibole: crocidolite, amosite, and actinolite.  All have long, silky to splintery fibres with appreciable tensile strength  and are of economic importance as asbestos.</p><p>amphibolite Vam-'fi-bo-.llA Igneous or metamorphic rock composed  largely or dominantly of amphibole minerals. For igneous rocks, the term  homblendite is usually used and is more restrictive; hornblende is the most  common amphibole. Metamorphic amphibolites are more widespread and  variable than igneous ones. Typically, they are medium- to coarse-grained  and are composed of hornblende and plagioclase. Basic igneous rocks such  as basalts and gabbros (see acid and basic rocks) can be the parent rocks  of amphibolite.</p><p>amphibolite facies \'fa-shez\ One of the major divisions of the min�  eral facies classification of metamorphic rocks, encompassing rocks that  formed under conditions of moderate to high temperatures (950�F, or  500�C, maximum) and pressures. Less-intense temperatures and pressures  form rocks of the epidote-amphiboute facies, and more-intense temperatures  and pressures form rocks of the granulite facies. Amphibole, diopside, epi-  dote, plagioclase, certain types of garnet, and wollastonite are minerals  typically found in amphibolite facies rocks. They are widely distributed  in Precambrian gneisses and probably formed in the deeper parts of folded  mountain belts.</p><p>Amphion and Zethus \'am-fe-9n... , ze-th3s\ In Greek mythology, twin  sons of Zeus by the mortal Antiope. As infants the two were left to die on  Mount Cithaeron, but were found and raised by a shepherd. Amphion  grew up to become a great musician and singer, while Zethus became a  hunter and herdsman. According to legend, they built the city of Thebes</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>64 I amphioxus &#x25BA; amygdule</p><p>after the stone blocks arranged themselves into walls at the sound of  Amphion�s lyre.

When their children were  killed by the gods, he committed suicide.</p><p>amphioxus \,am-fe-'ak-s3s\ or lancelet Vlan-sldtX Any of certain  small marine chordates (invertebrate subphylum Cephalochordata) found  widely on tropical and subtropical coasts and less commonly in temper�  ate waters. Seldom more than 3 in. (8 cm) long, they resemble small,  slender fishes without eyes or a definite head. They are grouped in sev�  eral species in two genera (Branchiostoma or Amphioxus, and Epigon-  ichthyes or Asymmetron). They spend much of their time buried in gravel  or mud on the ocean bottom, though they are able to swim, and feed by  filtering food particles from water passing through their gill slits. They  have no brain or distinct heart.</p><p>Amphipolis \am-'fi-p3-l3s\ Ancient city, eastern Macedonia, near the  mouth of the Struma River. Amphipolis was a strategic transportation cen�  tre, controlling the bridge over the river and the route from northern  Greece to the Dardanelles. Colonized by Athens in 437 bc, it was taken  by Sparta in 424 bc. It soon received its independence, only to be taken  by Philip II of Macedon in 358 bc. Later, under Roman rule, it was the  headquarters of the Roman governor of Macedonia.</p><p>amphitheater Freestanding, open-air round or oval structure with a  central arena and tiers of concentric seats. The amphitheater originated in  ancient Italy (Etruria and Campania) and reflects the entertainment forms  popular there, including gladiatorial games and contests of animals with  one another or of men with animals. The earliest extant amphitheater is one  built at Pompeii (c. 80 bc). Examples survive throughout the former prov�  inces of the Roman empire, the most famous being Rome�s Colosseum.</p><p>amplifier Device that responds to a small input signal (voltage, current,  or power) and delivers a larger output signal with the same waveform  features. Amplifiers are used in radio and television receivers, high-  fidelity audio equipment, and computers. Amplification can be provided  by electromechanical devices (e.g., transformers and generators) and  vacuum tubes, but most electronic systems now employ solid-state micro-  circuits. One amplifier is usually insufficient, so its output is fed into a  second, whose output is fed to a third, and so on, until the output level is  satisfactory.</p><p>amplitude modulation See AM</p><p>amputation Removal of any part of the body, usually surgical removal  of part or all of a limb. Congenital amputation means lack of a limb at birth  (see agenesis). Surgical amputation may be a lifesaving measure to prevent  excessive blood loss from injury or to check the spread of infection, gan�  grene, or malignant soft-tissue or bone tumours. Reconstructive surgery,  prompt treatment with blood and plasma, and rehabilitation have made  amputation rarer than in the past. Prostheses reduce handicaps for ampu�  tees, whose surgery may have been designed with a prosthesis in mind.</p><p>�Amr ibn al-'As Vam-or-.ib-on-ol-'asV (d. 663, Al-Fustat, Egypt) Arab  conqueror of Egypt. After accepting Islam (c. 630), he led a force to  Oman, where he converted the region�s rulers. He was a leader in the  Muslim force that conquered southwestern Palestine in the 630s but  gained fame when, on his own initiative, he set out to conquer Egypt,  succeeding (642) after a two-year campaign. A good administrator and  politician, late in his career he aided the governor of Syria, Mu'awiyah I,  against c Al 1, Islam�s fourth caliph.

In 1919 the British gov�  ernment of India enacted the Rowlatt Acts, extending its World War I  emergency powers to combat subversive activities. On April 13 a large  crowd gathered at Amritsar in the Punjab to protest the measures; troops  opened fire, killing about 379 and wounding some 1,200. The massacre  permanently scarred relations between India and Britain and was the pre�  lude to Mohandas K. Gandhi�s noncooperation movement of 1920-22.</p><p>Amsterdam City (pop., 2005 est.: city, 739,295; metro, area,  1,017,332), western Netherlands. It lies at the head of the IJsselmeer. It is  the nominal capital of The Netherlands, whose seat of government is at  The Hague. Originally a fishing village, it received its charter as a town in  1306. It joined the Hanseatic League in 1369 and grew steadily in the 14th  and 15th centuries. After the decline of Antwerp at the end of the 16th</p><p>century, Amsterdam became the source of growing Dutch commercial and  naval power. It was the centre for the Dutch East India and West India  companies and became the leading trade metropolis of Europe. It became  part of the Kingdom of Holland, which entered the Kingdom of the Neth�  erlands in 1815. After suffering a partial decline in the 18th century, its  prosperity increased when it became connected by canal to the North Sea  in the late 19th century. It was occupied by Germany in World War II.  After the war Amsterdam became known as a place of tolerance and lib�  eralism. The city is now a major European port and a hub for interna�  tional finance and trade.</p><p>Amtrak formally National Railroad Passenger Corp. Feder�  ally supported corporation that operates nearly all intercity passenger  trains in the U.S. It was established by Congress in 1970 in the face of  private railroads� heavy financial losses. Routes were cut back severely,  with service maintained only in highly populated areas and between the  largest cities. Amtrak pays the railroads to run passenger trains and com�  pensates them for the use of tracks and terminals. Amtrak bears all admin�  istrative costs and manages scheduling, route planning, and ticket sales.  Despite income from tickets and mail-carrying services, Amtrak requires  federal support to cover its operating costs.

It is one of the longest rivers in Central Asia, 1,578 mi (2,540 km) long  measured from the remotest sources of the Panj River; its other head-  stream is the Vakhsh. It flows west-northwest to its mouth on the Aral  Sea. It forms part of Afghanistan�s borders with Tajikistan, Uzbekistan,  and Turkmenistan and part of Uzbekistan�s border with Turkmenistan.</p><p>Amundsen Va-mun-sonV, Roald (Engelbregt Gravning) (b. July  16, 1872, Borge, near Oslo, Nor.�  disappeared June 18, 1928?, Arctic  Ocean) Norwegian explorer, leader  of the first group to reach the South  Pole. In 1897 he took part in a Bel�  gian expedition that was the first to  winter in the Antarctic. In 1903-05  he was the first to navigate the  Northwest Passage. He planned an  expedition to the North Pole, but,  after learning that Robert E. Peary had  reached that goal, he set off for the  South Pole in 1910. He prepared his  trip carefully and in October 1911 set  out with four men, 52 dogs, and four  sledges. He reached the South Pole  in December 1911, one month before  Robert Falcon Scon�s ill-fated  attempt. He returned to Norway and  established a successful shipping  business. In 1926 he and Umberto  Nobile (1885-1978) passed over the  North Pole in a dirigible. Amundsen  disappeared in 1928 while flying to rescue Nobile from a dirigible crash.</p><p>Amundsen Va-mon-sonV Gulf Southeastern extension of the Beaufort  Sea of the Arctic Ocean. Extending about 250 mi (400 km), the gulf is  bordered by Victoria Island on the east and separates Banks Island (north)  from the Canadian mainland (south). In 1850 the gulf was entered from  the west by the British explorer Robert McClure. It is named for Roald  Amundsen.</p><p>Amur \a-'mur\ River Chinese Heilong Vha-Tung\ Jiang or Hei-</p><p>lung Chiang River, northeastern Asia. The Amur proper begins at the  confluence of the Shilka and Argun rivers and is 1,755 mi (2,824 km)  long. It flows east-southeast along the Russian-Chinese border to Kha�  barovsk, Siberia, then northeast across Russian territory to empty into the  Tatar Strait. Among its tributaries are the Zeya, Bureya, and Ussuri rivers.  From the 18th century, Russians have settled to the north of the river and  Chinese to the south, a situation which at times has provoked border  clashes.</p><p>amygdule \9- , mig- l dyiil\ Secondary deposit of minerals found in a  rounded, elongated, or almond-shaped cavity in volcanic rock.

The disease usually occurs after  age 40, more often in men. Most victims die within two to five years from  respiratory muscle atrophy. ALS affects motor neurons; the muscles they  control become weak and atrophied, with debility usually beginning in  the hands and creeping slowly up to the shoulders. The lower limbs  become weak and spastic. Variants include progressive muscular atrophy  and progressive bulbar palsy. In 1993 the defective gene that accounts for  5-10% of cases was discovered; it produces an ineffective version of an  enzyme that neutralizes free radicals, which destroy motor neurons.</p><p>An Hyang See An Yu</p><p>An Lushan Van-'lii-'shanV Rebellion Rebellion beginning in 755 in  China led by An Lushan (703-757), a general of non-Chinese origin. An  Lushan rose through the ranks of the Tang-dynasty army in the 740s,  becoming a military governor and a favourite of the emperor, Xuanzong.  In 755 he turned his troops on the eastern capital city, Luoyang, and after  taking it he proclaimed himself emperor. Six months later his forces took  Chang 7 an, the western capital. He was murdered in 757, and the rebel�  lion was put down in 763. The Tang government was much weakened,  however, and the second half of the Tang dynasty and the subsequent Five  Dynasties period were troubled by chronic warlordism.</p><p>An Yu \'an-'yu\ or An Hyang \'an-'hyaq\ (b. 1243�d. 1306) Korean  Neo-Confucian scholar and educator. In 1287 he accompanied King  Chungnyol to the Mongol court in Beijing (Peking), where he encoun�  tered the texts of Zhu Xi. Returning to Korea, An Yu used Neo-Confucian  thought as the basis for promoting education. He helped reconstitute the  National Academy and established a state treasury for national education.  Eventually he became director of the Munmyo, the Korean national shrine  to culture. Known as an opponent of Son (Zen) Buddhism in Korea, he  was the most famous Confucian scholar of his era.

Found as piankton in shallow water and on moist soil, they occur in both  solitary and colonial forms and are capable of nitrogen fixation. In north�  ern latitudes in summer, extensive growth of Anabaena may form water  blooms that remain suspended instead of forming a surface scum. A toxic  substance produced is fatal to cattle and other animals if present in drink�  ing water in sufficient concentration.</p><p>Anabaptist Member of a movement of the Protestant Reformation char�  acterized by adult baptism. Anabaptists held that infants were not punish�  able for sin because they had no awareness of good and evil and thus could  not yet exercise free will, repent, and accept baptism. Denying the valid�  ity of infant baptism, they accepted adult baptism, which was regarded  as a second baptism by those outside the group who identified them as  Anabaptists (from the Greek for rebaptizers). Confident of living at the  end of time, early Anabaptists sought to restore the institutions and spirit  of the primitive church. The first adult baptisms took place outside Zurich  in early 1525. Most Anabaptists were pacifists and refused to swear civil  oaths. Thomas MOntzer advocated a more violent eschatology that called  for the overthrow of the rich by the poor and was executed after leading  the Thuringian peasant revolt (1525). Another group of Anabaptists, led  by John of Leiden, took control of the city of Munster and sought to  establish the millennial kingdom. Their excesses led to their violent sup�  pression in 1535 and further persecution and martyrdom of the Anabap�  tists. Many Anabaptists settled in Moravia, where they stressed the  community of goods modeled on the primitive church at Jerusalem. This  branch continues as the Hutterite movement, primarily in the western U.S.  and Canada. Increasingly persecuted throughout Europe, Anabaptists in  the Netherlands and northern Germany rallied under the leadership of  Menno Simonsz. and survive as the Mennonites.</p><p>anabolic \,a-n9-'ba-lik\ steroid Steroid hormone that increases tissue  growth. Anabolic steriods are given to elderly or postoperative patients  to promote muscle growth and tissue regeneration. Unsupervised use by  athletes to build muscle and improve strength can have serious harmful  effects, including coronary heart disease, sexual and reproductive disor�</p><p>ders, immunodeficiencies, liver damage, stunted growth, aggressive  behaviour, susceptibility to connective-tissue injury, and (in females) irre�  versible masculinization.</p><p>Anacletus \,an-3-'klet-9s\ II orig. Pietro Pierleoni (b. Rome�d.  Jan. 25, 1138, Rome) Antipope (1130-38). Named a cardinal at Rome in  1116, he was elected pope by a majority of cardinals in 1130, while a  minority created a schism by choosing Innocent II. Anacletus forced the  rival pope to flee to France, where Innocent was supported by a church  council and, especially, by Bernard of Clairvaux. Innocent�s supporters,  including the Holy Roman and Byzantine emperors, invaded Italy in an  unsuccessful effort to restore him. A second expedition in 1136 eroded  support for Anacletus, who died before the issue was resolved by the sub�  mission of his successor to Innocent.</p><p>anaconda Either of two South American snake species in the genus  Eunectes (family Boidae) that con�  strict their prey. The heavily built  giant anaconda, or great water boa,  is usually not more than 16 ft (5 m)  long but can be longer than 24 ft (7.5  m), rivaling the largest pythons in  length. The yellow anaconda is much  smaller. Typically dark green with  alternating oval black spots, the giant  anaconda lives along tropical rivers  east of the Andes and in Trinidad. It  kills at night by lying in wait in  water; it constricts prey as large as  young pigs or caimans and occasionally forages in trees for birds. It may  bear 75 live young at a time.</p><p>Anacreon or Anakreon \3-'nak-re-3n\ (b. c. 582 bc, Teos, Ionia�d.  c. 485) Last great lyric poet of Asian Greece. Only fragments of his poetry  have survived. Though he may have written serious poems, the poems  quoted by later writers are chiefly in praise of love, wine, and revelry. His  sentiments and style were widely imitated, and the anacreontic metre in  poetry was named for him.</p><p>Anadolu See Anatolia</p><p>Anaheim City (pop., 2000: 328,014), southwestern California, U.S.  Lying on the plain of the Santa Ana River 25 mi (40 km) southeast of Los  Angeles, it was founded by German immigrants in 1857 as a cooperative  agricultural community.

Waste products move from  the rectum to the anal canal. The human anal canal is 1-1.5 in. (2.5^4 cm)  long and has three parts: upper, with longitudinal folds (rectal columns);  lower, with involuntary and voluntary constrictive muscles (sphincters) to  control discharge of feces; and the anal opening itself. Enlargements of  the ends of rectal and anal veins are called hemorrhoids.</p><p>Analects See Lunyu</p><p>analgesic \,an-9l-'je-zik\ Drug that relieves pain without blocking nerve  impulse conduction or markedly altering sensory function (see nervous  system). Two classes are defined by the type of pain-relieving action. Opi�  oids (opiates and synthetic narcotics; see opium) act on brain receptors to  inhibit pain impulses. They may be used for short- or long-term pain  relief, usually by prescription, but carry a risk of drug addiction. Non�  opioids, used mostly for short-term relief and modest pain, are available  without prescription. They include NSAIDs (including aspirin and ibupro-  fen) and acetaminophen; all act by inhibiting synthesis of prostaglandins,  molecules involved in the peripheral perception of pain.</p><p>analog computer Computer in which continuously variable physical  quantities, such as electrical potential, fluid pressure, or mechanical  motion, are used to represent (analogously) the quantities in the problem  to be solved. The analog system is set up according to initial conditions  and then allowed to change freely. Answers to the problem are obtained  by measuring the variables in the analog model. Analog computers are  especially well suited to simulating dynamic systems; such simulations</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>66 I analysis &#x25BA; Anasazi</p><p>may be conducted in real time or at greatly accelerated rates, allowing  experimentation by performing many runs with different variables. They  have been widely used in simulating the operation of aircraft, nuclear  power plants, and industrial chemical processes. See also digital computer.</p><p>analysis In chemistry, the determination of the properties and compo�  sition of samples of materials; qualitative analysis establishes what is  there, and quantitative analysis measures how much. A large body of sys�  tematic procedures (analytical chemistry) has evolved in close associa�  tion with other branches of the physical sciences since their beginnings.  A sample of a single compound may be analyzed to establish its elemen�  tal composition (see element, molecular weight) or molecular structure;  many measurements use spectroscopy and spectrophotometry. A mixed  sample is usually analyzed by separating, detecting, and identifying its  components by methods that depend on differences in their properties  (e.g., volatility, mobility in an electric or gravitational field, distribution  between liquids that do not mix). The many types of chromatography are  increasingly useful, particularly with biological and biochemical samples.</p><p>analysis Field of mathematics that incorporates the methods of algebra  and calculus �specifically of limits, continuity, and infinite series �to ana�  lyze classes of functions and equations having general properties (e.g.,  differentiability). Analysis builds on the work of G.W. Leibniz and Isaac  Newton by exploring the applications of the derivative and the integral.  Several distinct but related subfields have developed, including the cal�  culus of variations, differential equations, Fourier analysis (see Fourier  transform), complex analysis, vector and tensor analysis, real analysis, and  FUNCTIONAL ANALYSIS. See also NUMERICAL ANALYSIS.</p><p>analytic geometry Investigation of geometric objects using coordi�  nate systems. Because Rene Descartes was the first to apply algebra to  geometry, it is also known as Cartesian geometry. It springs from the idea  that any point in two-dimensional space can be represented by two num�  bers and any point in three-dimensional space by three. Because lines,  circles, spheres, and other figures can be thought of as collections of points  in space that satisfy certain equations, they can be explored via equations  and formulas rather than graphs. Most of analytic geometry deals with the  conic sections. Because these are defined using the notion of fixed dis�  tance, each section can be represented by a general equation derived from  the DISTANCE FORMULA.</p><p>analytic philosophy Philosophical tradition that emphasizes the logi�  cal analysis of concepts and the study of the language in which they are  expressed. It has been the dominant approach in philosophy in the  English-speaking world from the early 20th century. With respect to its  problems, methods, and style, it is often contrasted with Continental phi�  losophy, though the significance of the opposition has been widely chal�  lenged. Analytic philosophers have differed regarding the nature of  so-called �ordinary� language and the methodological value of appeals to  ordinary usage in the logical analysis of concepts. Those known as for�  malists hold that, because ordinary language is potentially a source of  conceptual confusion, philosophy and science should be conducted in a  logically transparent formal language based on modern mathematical, or  symbolic, logic. Those known as informalists reject this view, arguing that  attempts to �improve� ordinary language in this way inevitably oversim�  plify or falsify it, thereby creating conceptual confusion of just the sort  that the formalists are concerned to avoid. Three figures conventionally  recognized as founders of the tradition are Gottlob Frege, G.E. Moore,  and Bertrand Russell. Other major figures include Ludwig Wittgenstein, A.J.  Ayer, Rudolf Carnap, J.L. Austin, W.V.O. Quine, and David Lewis (1941�  2001). See also logical positivism; Vienna Circle.</p><p>analytic psychology Psychoanalytic method of Carl Jung as he dis�  tinguished it from that of Sigmund Freud. Jung attached less importance  than did Freud to the role of childhood sexual conflicts in the develop�  ment of neurosis. Moreover, he defined the unconscious to include both  the individual�s own unconscious and that inherited, partly in the form of  archetypes, from his or her ancestors (the �collective unconscious�). He  classified people into introvert and extravert types and further distin�  guished them according to four primary functions of the mind�thinking,  feeling, sensation, and intuition�one or more of which predominated in  any given person.</p><p>analytic-synthetic distinction In both logic and epistemology, the  distinction (derived from Immanuel Kant) between statements whose predi�  cate is included in the subject (analytic statements) and statements whose  predicate is not included in the subject (synthetic statements). Some phi�</p><p>losophers prefer to define as analytic all statements whose denial would  be self-contradictory, and to define the term synthetic as meaning �not  analytic.� The distinction, introduced by Kant in The Critique of Pure  Reason , aroused extensive debate in the mid-20th century, particularly in  view of objections raised by W.V.O. Quine.</p><p>anamorphosis \ l an-9-mor- , fo-sis\ Drawing or painting technique that  gives a distorted image of the subject when seen from the usual view�  point, but when viewed from a particular angle or reflected in a curved  mirror shows it in true proportion. Its purpose is to amuse or mystify. It  was a curious by-product of the discovery of perspective in the 14th-15th  century and was regarded as a display of technical virtuosity. The first  examples appear in Leonardo da Vinci�s notebooks.</p><p>Ananda Va-non-doV (fl. 6th century bc, India) First cousin and disciple  of the Buddha. A monk who served as the Buddha�s personal attendant,  he became known as the �beloved disciple.� It was Ananda who persuaded  the Buddha to allow women to become nuns. By tradition, he was the  only intimate disciple of the Buddha who had not attained enlightenment  before his master�s death; he attained that state just before the first Bud�  dhist Council (c. 544 or 480 bc), when he recited from memory the Sutta  Pitaka. He is represented as the author of several Buddhist discourses.</p><p>anaphylaxis \,an-9-fi-'lak-sis\ Severe, immediate, potentially fatal  bodily reaction to contact with a substance (antigen) to which the indi�  vidual has previously been exposed. Often triggered by antiserum, anti�  biotics, or insect stings, the reaction�s symptoms include skin flushing,  bronchial swelling (with difficulty breathing), and loss of consciousness.  Shock may follow. Milder cases may involve hives and severe headache.  Treatment, consisting of injection of epinephrine, followed by antihistamines,  cortisone, or similar drugs, must begin within minutes. Anaphylaxis may  be caused by extremely small amounts of antigen.</p><p>anarchism Van-or-.kiz-omV Political theory holding all forms of govern�  ment authority to be unnecessary and undesirable and advocating a society  based on voluntary cooperation and free association of individuals and  groups. The word was used only pejoratively until Pierre-Joseph Proudhon,  now regarded as the founder of anarchism, adopted it in What is Property?  (1840). The anarchist Mikhail Bakunin clashed with Karl Marx at the First  International; when it was dissolved in 1872, Bakunin�s followers retained  control of workers� organizations in Latin countries such as Spain and Italy.  Even anarchists who believed that the transition to a government-free soci�  ety required violent revolution disagreed on the nature of the transition.  Anarcho-SYNDICAUSM, which developed in the late 1880s, emphasized  labour unions ( syndicats ) and called for general strikes to paralyze the  state. In the 19th and 20th centuries, anarchism also inspired experimental  communities, including New Lanark in Britain and Brook Farm in the U.S.  During the early months of the Spanish Civil War, anarchist militias were in  virtual control of much of eastern Spain, where they established hundreds  of anarchist collectives. Suppressed as an organized movement by fascism  in the 1930s, anarchism reemerged in the 1950s and �60s through its influ�  ence on the civil rights movement and the student movements in the U.S. and  Europe. The radical ECOLOGY movement in the 1970s also was inspired by  anarchist ideas. Beginning in 1999, anarchist-led street demonstrations  against the World Bank and International Monetary Fund received unprec�  edented publicity and inspired new anarchist groups, periodicals, and Inter�  net sites. Anarchist themes are reflected in the work of many 20th-century  artists, writers, and musicians, including Pablo Picasso, the American poets  of the Beat movement, the Spanish Surrealist filmmaker Luis Bunuel, and the  American composer John Cage.</p><p>Anasazi \,a-n3-'sa-ze\ culture North American Indian civilization that  developed from c. ad 100 to historic times, centring on the area where the  present-day boundaries of the U.S. states of Arizona, New Mexico, Colo�  rado, and Utah intersect. Anasazi is the Navajo word for �Ancient  Enemy�; the Hopi prefer the term Hisatsinom, meaning �Ancient People.�  Anasazi is the term most commonly used to refer to the ancestors of con�  temporary Pueblo Indian peoples. Anasazi civilization is customarily  divided into several periods: Basket Maker (ad 100-500), Modified Bas�  ket Maker (500-700), Developmental Pueblo (700-1050), Classic Pueblo  (1050-1300), Regressive Pueblo (1300-1700), and Modern Pueblo  (1700-the present). As among present-day Pueblo peoples, religion in the  Anasazi culture was highly developed and centred on rites partly con�  ducted in underground circular chambers called kivas. The best-known  Anasazi ruins are the cliff dwellings at Mesa Verde (Colo.) and Chaco  Canyon (N.M.).</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Anastasia &#x25BA; anchovy I 67</p><p>Anastasia Russian Anastasiya Nikolayevna (b.

She was executed at  age 17 with the other members of her immediate family by the Bolshe�  viks in the Russian Revolution of 1917. After the executions several  women outside Russia claimed her identity, making her the subject of  periodic popular conjecture and publicity. Some also claimed to be heir  to the Romanov fortune held in Swiss banks. The most famous was Anna  Anderson (d. 1984), a Pole married to a U.S. history professor; her claim  was finally rejected in 1970, and later genetic tests proved there was no  connection between Anderson and the Romanovs.</p><p>Anastasius \,an-3-'sta-zh3s\ I (b. 430?, Dyrrhachium, Epirus Vetus�d.

Anastasius reformed the monetary and taxation systems and expelled  rebel tribes from Constantinople, building a wall to protect the capital  against raiders. He recognized Theodoric�s rule in Italy (497) but later sent  a fleet to ravage the Italian coast. War with Persia (502-5) ended when  he agreed to pay tribute to the Persian king. Anastasius accepted the  Monophysite doctrine, a stand that caused unrest in Byzantium but fos�  tered peace with Egypt and Syria.</p><p>Anath \'an-ath\ Chief western Semitic goddess of love and war, sister  and helpmate to Baal, whom she retrieved from the land of the dead.

During the Hellenistic Age, Anath and  Astarte were merged into Atargatis.</p><p>Anatolia or Asia Minor Turkish Anadolu X.a-na-'do-liiN Peninsula  forming the western extremity of Asia. It is bounded by the Black Sea to  the north, the Mediterranean Sea to the south, and the Aegean Sea to the  west. Its eastern boundary is generally marked by the Anti-Taurus Moun�  tains. Anatolia is roughly contiguous with the Asian portion of the mod�  ern Republic of Turkey. Because of its location at the point where Asia and  Europe meet, it has long been the scene of numerous migrations and con�  quests. It was the original location of the kingdom of Hittites (c. 1700-  1180 bc). Later, Indo-European peoples, possibly Thracian, established  the Phrygian kingdom. In the 6th century bc the Persian Achaemenian  dynasty came to rule the area; it was conquered by Alexander the Great in  334 bc. Beginning in the 1st century bc, the area was absorbed into the  Roman Republic and Empire. When the empire split in ad 395, Anatolia  became part of the Byzantine Empire. The area endured invasions by Arabs,  Turks, Crusaders, Mongols, and the Turkic army of Timur before the Otto�  man Empire established full control in the 15th century. From 1923 its his�  tory was that of modern Turkey.</p><p>Anatolian languages Branch of the Indo-European language family  spoken in Anatolia in the 2nd-lst millennia bc. The attested Anatolian  languages are Hittite, Palaic, Luwian (Luvian), Hieroglyphic Luwian,  Lycian, and Lydian. Hittite, by far the most copiously attested of the  group, is known chiefly from a vast archive of cuneiform tablets found in  1905 at Hattusas (now Bogazkoy, in north-central Turkey), the capital of  the Hittite empire; Hittite texts date from the 16th to 13th century bc. By  the late Roman or early Byzantine period at the latest, Anatolian languages  had all become extinct. Several non-Indo-European languages of ancient  Anatolia, all known from cuneiform texts, are also sometimes considered  Anatolian languages: Hattie, spoken in central Anatolia before the com�  ing of the Hittites and known solely from words and texts preserved by  Hittite scribes; Hurrian, spoken in the 2nd millennium bc in northern  Mesopotamia and southeastern Anatolia; and Urartian (Urartean), known  from northwestern Anatolian texts of the 9th-7th centuries bc.</p><p>anatomy Biological field that deals with bodily structures as revealed  by dissection. Herophilus first laid the factual groundwork for gross  anatomy, the study of structures large enough to see without a microscope.  Galen�s ideas were the authority for anatomy in Europe until Andreas  Vesauus�s methods placed it on a firm foundation of observed fact. The  microscope permitted the discovery of tiny structures (e.g., capillaries and  cells), the subject of microscopic anatomy. Crucial advances in this area�  including the microtome, which slices specimens into extremely thin sec�  tions, and staining�led to the new fields of cytology and histology.  Electron microscopy opened up the study of subcellular structures, and  X-ray diffraction gave rise to the new subspecialty of molecular anatomy.</p><p>Comparative anatomy compares similar structures in different animals to  see how they have changed with evolution.</p><p>Anaxagoras \,an-ak-'sag-3-r3s\ (b. c. 500, Clazomenae, Anatolia�d.  c. 428 bc, Lampsacus) Greek philosopher. Though only a few fragments  of his writings have survived, he is remembered for his cosmology and  for his discovery of the true cause of eclipses. His cosmology grew out  of the efforts of earlier pre-Socratics to explain the physical universe in  terms of a single element. The most original aspect of his system was his  doctrine of nous (�mind,� or �reason�), according to which the cosmos,  including all living things, was created by mind in a process of attraction  of �like to like�; mind also accounts for the power of living things to  extract nourishment from surrounding substances.</p><p>Anaximander Xo-'nak-so-.man-doA (b. 610 bc, Miletus�d. 546/545  bc) Greek philosopher, often called  the founder of astronomy. He appar�  ently wrote treatises on geography,  astronomy, and cosmology that sur�  vived for several centuries and made  a map of the known world. He was  the first thinker to develop a cosmol�  ogy. A rationalist, he prized symme�  try and used geometry and  mathematical proportions to help  map the heavens; his theories thus  departed from earlier, more mystical  conceptions and foreshadowed the  achievements of later astronomers.</p><p>Whereas earlier theories had sug�  gested Earth was suspended or sup�  ported from elsewhere in the  heavens, Anaximander asserted that  Earth remained unsupported at the  centre of the universe because it had no reason to move in any direction.</p><p>Anaximenes X.an-ak-'sim-o-.nezX (fl. c. 545 bc) Greek philosopher of  nature. With Thales and Anaximander, he is one of three Milesian thinkers  (see Miletus) traditionally considered the first philosophers of the West�  ern world. He defined the essence of matter as aer (�air�) and explained  the densities of various types of matter in terms of varying degrees of  condensation of moisture. His writings no longer exist except as quoted  by later authors.</p><p>ANC See African National Congress</p><p>ancestor worship Religious beliefs or practices that involve address�  ing prayers or offerings to the spirits of dead relatives. It existed among  the ancient Greeks, other Mediterranean peoples, and the ancient Euro�  peans; it also plays a major role in traditional African religions. The dead  are related to the family, clan, tribe, or village; mythical ancestors may  be included. They may be friendly, or they may be displeased and require  propitiation. Commemorative ceremonies are sometimes held at graves  or monuments and may include prayers, offerings, sacrifices, and festi�  vals of honor. Worship of individual ancestors is common; it may be  combined with communal forms of worship, as in the case of the Roman  emperor cult. An ancestor whose deeds are heroic may attain the status  of a god. In China and Japan, ancestor worship (more accurately, ances�  tor reverence) has declined with the decline in the size and importance  of kinship groups.</p><p>Anchorage Seaport, largest city (pop., 2000: 260,283), and chief com�  mercial centre of Alaska, U.S. It lies at the head of Cook Inlet near the  base of the Kenai Peninsula.

Founded by colonists from Syracuse c. 390 bc, it was taken  by Rome in the 2nd century bc. It became a flourishing port particularly  favoured by Trajan, who enlarged the harbour. It was attached to the Holy  Roman Empire in the 12th century; in the 16th century it came under papal  protection, which was largely maintained until Ancona became part of  Italy in 1861. It underwent severe bombing in World War II, but many  notable Roman and medieval landmarks survive.</p><p>Anda See Altan</p><p>Andalusia X.an-do-lii-'se-oV Spanish Andalucia Autonomous com�  munity (pop., 2001: 7,357,558) and historic region, southern Spain. It  occupies an area of 33,821 sq mi (87,597 sq km); the capital is Sevilla. It  is traversed by mountain ranges, including the Sierra Morena and Sierra  Nevada; its main river is the Guadalquivir. Andalusia has a long history  of inhabitation: by the Phoenicians (9th century bc), the Carthaginians (5th  century bc), and the Romans (3rd century bc). The Arabic name  Al-Andalus was originally applied by the Moors to the whole Iberian  Peninsula. When the Umayyad dynasty established its court at Cordoba,  this area became the peninsula�s intellectual and political centre. It  returned to Spanish Christian rule in 1492 and remained a province until  divided in 1833 into the eight modern provinces. A mining and agricul�  tural region, Andalusia also features beaches along the Costa del Sol that  attract the tourist trade.</p><p>Andaman and Nicobar \'an-d3-m3n... , nik-6- 1 bar\ Islands Union  territory (pop., 2001: 356,152), India.

Bounded  by the Andaman and Nicobar Islands, Myanmar, the Malay Peninsula, and  the Strait of Malacca and Sumatra, it covers some 308,000 sq mi (798,000  sq km). Trading vessels have plied the sea since ancient times. Part of the  early coastal trade route between India and China, from the 8th century  it formed a route between India (and Sri Lanka) and Myanmar. Its larg�  est modem ports are George Town (Malaysia) and Yangon (Myanmar).  A large earthquake-generated tsunami in 2004 inundated many of the sea�s  coastal areas.</p><p>Andania mysteries Ancient Greek mystery cult, held in honor of the  goddess Demeter and her daughter Kore (Persephone) at Andania in Mes-  senia.

April 2, 1805, Odense, near Copen�  hagen, Den.�d. Aug. 4, 1875, Copenhagen) Danish writer of fairy tales.  Though reared in poverty, he received a university education. In his many  collections of tales, published 1835-72, he broke with literary tradition  and employed the idioms and constructions of spoken language. His sto�  ries are imaginative combinations of universal elements from folk legend  and include such favourites as �The Ugly Duckling� and �The Emperor�s  New Clothes.� While some reveal an optimistic belief in the ultimate tri�  umph of goodness and beauty (e.g., �The Snow Queen�), others are deeply  pessimistic. Part of what makes his tales compelling is the way they iden�  tify with the unfortunate and outcast. He also wrote plays, novels, poems,  travel books, and several autobiographies.</p><p>Anderson, Dame Judith orig. Frances Margaret Anderson</p><p>(b. Feb. 10, 1898, Adelaide, S.Aus., Australia�d.

After studying at Barnard College and Columbia University,  she began giving performances in New York City in 1973 while teaching  art history at the City University of New York. Combining elements of  music, theatre (dance, mime), film, technology, and speech, she satirized  media and mass culture, using the tools they themselves provide. The  pop-music success of her song �O Superman� (1980) led her to record  two albums, Big Science (1982) and Mister Heartbreak (1984). Her major  1980s piece was the multimedia extravaganza United States.

Winesburg, Ohio (1919), a collection of  interrelated sketches and tales about the obscure lives of the citizens of a  small town, was his first mature book and made his reputation. His short  stories were collected in The Triumph of the Egg (1921), Horses and Men  (1923), and Death in the Woods (1933). His prose style, based on every�  day speech and influenced by the experimental writing of Gertrude Stein,  in turn influenced such writers as Ernest Hemingway and William Faulkner.</p><p>Andersonville Village, southwest-central Georgia, U.S. It was the site  of a Confederate military prison in 1 864-65 during the American Civil War.

Andersonville is also the site of the National Prisoner of War Museum.</p><p>Andes Mountains Mountain system, western South America. One of  the great natural features of the globe, the Andes extend north-south about  5,500 mi (8,900 km). They run parallel to the Caribbean Sea coast in Ven�  ezuela before turning southwest and entering Colombia. There they form  three distinct massifs: the Cordilleras Oriental, Central, and Occidental.  In Ecuador they form two parallel cordilleras, one facing the Pacific and  the other descending toward the Amazon River basin. These ranges con�  tinue southward into Peru; the highest Peruvian peak is Mount Huascaran  (22,205 ft [6,768 m]) in the Cordillera Blanca. In Bolivia the Andes again  form two distinct regions; between them lies the Altiplano. Along the bor�  der of Chile and Argentina, they form a complex chain that includes their  highest peak, Mount Aconcagua, which reaches an elevation of 22,834  ft (6,960 m). In southern Chile part of the cordillera descends beneath the  sea and forms numerous islands. The Andes are studded with a number  of volcanoes that form part of the Circum-Pacific chain known as the Ring  of Fire. The Andes mountain system is the source of many rivers, includ�  ing the Amazon and Pilcomayo.</p><p>andesite Van-do-.ziA Any member of a large family of rocks that occur  in most of the world�s volcanic areas, mainly as surface deposits and to  a lesser extent as dikes and small plugs.

They also occur in  abundance in volcanoes along practically the entire margin of the Pacific  basin. Andesites are most often porphyritic (having distinct crystals in a  fine-grained base) rocks.</p><p>Andhra Pradesh X.an-dro-pro-'deshX State (pop., 2001: 76,210,007),  southeastern India.

Covering  106,204 sq mi (275,068 sq km), it was created in 1953 and achieved its  present-day form in 1960; its capital is Hyderabad. Its name derives from  the Telugu-speaking Andhra people, who have long inhabited the area.  Many dynasties have flourished here, dating to the 3rd century bc. The  area came under British influence in the 17th century; in the 19th century  the Andhras played a decisive role in the rise of Indian nationalism. The  state�s economy, once primarily agricultural, has become one of the most  industrialized in India.</p><p>Andijon \,an-di-'jan\ or Andizhan \,an-di-'zhan\ City (pop., 1998 est.:  288,000), eastern Uzbekistan.

It was placed under the joint suzerainty of the French counts of  Foix and the Spanish bishops of Urgel in 1278, and it was subsequently  governed jointly by the Spanish bishop of Urgel and the French head of  state. This feudal system of government, the last in Europe, continued  until 1993, when a constitution was adopted that transferred most of the  coprinces� powers to the Andorran General Council, which is elected by  universal suffrage.

To appease the gods, Andromeda was chained  to a rock and left to be devoured by the monster. Perseus flew by on  Pegasus, fell in love with Andromeda, and slew the monster. She married  him and bore him six sons and a daughter. After her death she became a  constellation.</p><p>Andromeda \an-'dro-m3-d3\ Galaxy or M31 Great spiral galaxy in  the constellation Andromeda. It is the nearest spiral galaxy outside the  Milky Way Galaxy and one of the few visible to the unaided eye, appear�  ing as a milky blur. About 2 million light-years from Earth, it has a diam�  eter of about 200,000 light-years, which makes it the largest galaxy in the  Local Group. For centuries astronomers considered it part of the Milky  Way; only in the 1920s did Edwin Hubble determine conclusively that it  was a separate galaxy.</p><p>Andronicus I Comnenus \ I an-dr3- , nI-k9s...kam-'ne-n3s\ (b. 1118,  Constantinople�d. Sept. 1185, Constantinople) Byzantine emperor  (1183-85), the last of the Comnenus dynasty. A cousin of Manuel I Com�  nenus, he raised an army and seized power in 1182, causing a massacre of  Westerners in Constantinople. He was crowned coemperor with Alexius II  in 1183; two months later he had Alexius strangled and married his  13-year-old widow. Andronicus reformed the Byzantine government and  asserted the independence of the Eastern church, provoking a Sicilian Nor�  man invasion. News of the Normans� approach led to a revolt, in which  Andronicus was killed by a mob and Isaac II Angelus was declared emperor.</p><p>Andronicus II Palaeologus \,pa-le-'al-3-g3s\ (b. c. 1260,  Constantinople�d. Feb. 13, 1332, Constantinople) Byzantine emperor  (1282-1328). The son of Michael VIII Palaeologus, he was an intellectual  and theologian rather than a soldier and statesman, and during his reign  the Byzantine Empire declined to the status of a minor state. Ottoman Turks  controlled Anatolia by 1300, and Serbs dominated the Balkans. By sid�  ing with Genoa in the war between Genoa and Venice, Andronicus pro�  voked an attack by the Venetian navy. Despite the rising political disorder,  he promoted Byzantine art and the independence of the Eastern Ortho�  dox church. Deposed by his grandson Andronicus III Palaeologus, he  entered a monastery.</p><p>Andronicus III Palaeologus (b. March 25, 1297, Constanti�  nople�d. June 15, 1341, Constantinople) Byzantine emperor (1328-41).  He forced his grandfather Andronicus II Palaeologus to make him coem�  peror (1325) and then to abdicate (1328). He relied on John VI Cantacuze-  nus to reform the courts and rebuild the imperial navy. He ceded control  of Macedonia to Serbia (1334) and lost land to the Ottoman Turks in Ana�  tolia, but he regained some Aegean islands from the Genoese and reas�  serted control of Epirus and Thessaly.</p><p>Andropov Van-'dro-.pofV Yury (Vladimirovich) (b.

His tenure as head of the KGB (1967-82) was noted for  its suppression of political dissidents. In 1982 he succeeded Leonid Brezh�  nev as general secretary of the party�s Central Committee, but ill health  quickly overtook him, and he accomplished little else before his death 15  months later.</p><p>Andros \,an-dr3s\ Island (pop., 2000: 7,686), The Bahamas.

He returned in 1686 as gov�  ernor of the Dominion of New England, a kind of supercolony imposed  by Britain. His interference in local government aroused sharp resentment  among the colonists, and in 1688 they revolted and imprisoned him.  Andros was recalled to England but returned as governor of Virginia  (1692) and Maryland (1693-94).</p><p>anemia Condition in which erythrocytes are reduced in number or vol�  ume or are deficient in hemoglobin. The patient is usually noticeably pale.  Close to 100 varieties exist (including aplastic anemia, pernicious anemia,  and sickle-cell anemia), distinguished by cause; erythrocyte size, shape, and  hemoglobin content; and symptoms. Anemia may result from blood loss;  increased destruction, reduced production, or inhibited formation of red  cells; or hormone deficiency.

The most familiar instruments for measuring wind speeds are  the revolving cups that drive an electric generator (useful range approxi�  mately 5-100 knots). For very low airspeeds, a unit in which revolving  vanes operate a counter measures the airspeed. For strong, steady wind  speeds (in wind tunnels and aboard aircraft in flight), a pitot-tube anemom�  eter is often used; the pressure difference between the interior of the tube  and the surrounding air can be measured and converted to airspeed.</p><p>anemone \3-'ne-m3-ne\ Any of about 120 species of perennial plants  that make up the genus Anemone , in the buttercup family, many of which  are cultivated for their colourful flowers. Though found throughout the  world, anemones are most common in woodlands and meadows of the  northern temperate zone. Many varieties of the tuberous poppylike  anemone A. coronaria are grown for the garden and florist trade. Popular  spring-flowering species include A. apennina, A. blanda, and A. pavon-  ina. Other species, such as the Japanese anemone (A. hupehensis), are  favourite border plants for autumn flowering. The European wood  anemone, A. nemorosa , causes blistering of the skin and was once used  as an ingredient in medicines. Anemones are also known colloquially as  pasqueflowers or windflowers.</p><p>anesthesiology X.a-nss-.the-ze-'al-s-jeN Medical specialty dealing  with anesthesia and related matters, including resuscitation and pain.  Originally concerned only with general anesthesia in the operating room,  anesthesiology now includes epidural anesthesia (injection of local anes�  thetics into the spinal fluid, cutting off feeling below the point of injec�  tion); artificial respiratory support during operations requiring paralyzing  drugs that render patients unable to breathe; clinical management of all  unconscious patients; management of pain relief and cardiac and respi�  ratory resuscitation problems; respiratory therapy; and treatment of fluid,  electrolyte, and metabolic disturbances. Progress in anesthesiology has  made possible more complex operations and surgery for more critically  ill patients. The anesthesiologist�s role has become increasingly impor�  tant and complex.</p><p>anesthetic \,an-es-'thet-ik\ Agent that produces a local or general loss  of sensation, including pain, and therefore is useful in surgery and den�  tistry. General anesthesia induces loss of consciousness, most often using  hydrocarbons (e.g., cyclopropane, ethylene); halogenated (see halogen)  hydrocarbons (e.g., chloroform, ethyl chloride, trichloroethylene); ethers  (e.g., ethyl ether or vinyl ether); or other compounds, such as tribromo-  ethanol, nitrous oxide, or barbiturates. Local anesthesia induces loss of sen�  sation in one area of the body by blocking nerve conduction (see nervous  system, neuron), usually with alkaloids such as cocaine or synthetic sub�  stitutes (e.g., lidocaine).

The outlet  for Lake Baikal, it is a major tributary of the Yenisey River, which it joins  near Yeniseysk. It is about 1,105 mi (1,779 km) long, and with its many  rapids, it provides great potential for hydroelectric power. Some existing  dams and power stations provide power in the Irkutsk industrial area.</p><p>angel Primarily in Western religions, any of numerous benevolent spiri�  tual beings who mediate between heaven and earth. They often serve as  messengers or servants of God or as guardians of an individual or nation.  In Zoroastrianism the amesha spenta are arranged in a hierarchy of seven.  Judaism and Christianity base their notion of angels on references in the  Hebrew scriptures to divine servants and to the heavenly hosts. Two arch�  angels (Michael and Gabriel) are mentioned in the Old Testament and two  others (Raphael and Uriel) in the Apocrypha. Angels are mentioned  throughout the Christian scriptures, and Christian tradition identifies nine  orders of angels. Islam�s hierarchy of angels descends from the four throne  bearers of God to the cherubim who praise God, the four archangels, and  lesser angels such as the hafazah (guardian angels).

The Angevin dynasty over�  laps with the house of Plantagenet but is usually said to consist of only the  English kings Henry II, Richard I, and John. Henry established the Angevin  empire in the 1150s when he took control of Normandy, Anjou, Maine,  and, through his marriage to Eleanor, Aquitaine. When he became the king  of England in 1154, Henry extended the Angevin holdings from Scotland  to the Pyrenees. English claims to French territory led to the Hundred  Years' War; by 1558 the English had lost all their former French lands.</p><p>Angilbert Vaq-gsl-.bsrtV Saint (b. c. 740, Aachen, kingdom of the  Franks�d.

In 800 he accompa�  nied Charlemagne to Rome. He was made lay abbot of Centula (St.-  Riquier), Picardy, in 794. His graceful and sophisticated Latin poems offer  a picture of life in the imperial circle. Charlemagne�s daughter Bertha and  Angilbert were the parents of the historian Nithard.</p><p>angina pectoris Van-'jl-ns-'pek-ts-rssV Spasm of chest pain, caused  when the heart�s oxygen demand temporarily outpaces its blood supply,  usually because of coronary heart disease. A deep, viselike pain in the heart  and stomach area commonly spreads to the left arm. Exertion or emo�  tional stress can bring on angina, obliging the victim to rest until the pain  subsides. If rest does not help, drugs can dilate the blood vessels. As heart  disease worsens, angina recurs with less exertion.</p><p>angiocardiography \ 1 an-je-o- 1 kar-de- , ag-r3-fe\ Method of diagnostic  imaging that shows the flow of blood through the heart and great vessels.

After  the Siamese conquest of the Khmer in the 15th century, the ruined city  and its temples were buried in the jungle. When the French colonial  regime was established in 1863, the entire site became the focus of schol�  arly interest. During Cambodia�s political upheavals of the late 20th cen�  tury there was some war damage, but the major problem was one of  neglect.

Their language was known, even then, as Englisc, and  they gave their name to England.</p><p>angle In geometry, a pair of rays (see line) sharing a common endpoint  (the vertex). An angle may be thought of as the rotation of a single ray  from an initial to a terminal position. Clockwise rotation is considered  negative and counterclockwise rotation positive. Either may be measured  in degrees (one full rotation = 360�) or radians (one full rotation = 2k  rad). A 90� angle is called a right angle. Any angle less than 90� is an  acute angle. Any angle more than 90� but less than 180� is an obtuse angle.</p><p>anglerfish Any of about 210 species of marine fishes (order Lophii-  formes) named for their method of �fishing� for prey. The foremost spine  of the dorsal fin is located on the head and is modified into a �fishing rod�  tipped with a fleshy �bait.� Prey fishes attracted to this lure stray close  enough for the anglerfish to swallow them. Often bizarre in form, angler�  fishes are also characterized by small gill openings and by limblike pec�  toral and (in some species) pelvic fins. Most species inhabit the sea  bottom. In some species the small male bites into the larger female�s body,  his mouth fuses with the skin, and the bloodstreams of the two become  permanently connected.</p><p>Anglesey Vaq-gal-seV Isle of ancient Mona County (pop., 2001:  66,828), Wales.

King  Bodawpaya�s conquest of Arakan, which bordered on British-controlled  territory in India, led to border conflicts between Arakan freedom fight�  ers and the Burmans. When the Burmans crossed the border into Bengal,  the British responded in force, taking Rangoon (now Yangon). The result�  ing two-year conflict ended with a treaty that gave Britain Arakan and  Assam and required the Burmans to pay an indemnity. Another war  erupted 25 years later when a British naval officer seized a ship that  belonged to the Burman king; the British advanced into and soon occu�  pied all of Lower Burma. A third war was sparked by threats to the Brit�  ish teak monopolies in Lower Burma and Burman overtures to the French;  as a result, the British annexed Upper Burma (formalized in 1886), thus  ending Burman independence.</p><p>Anglo-Dutch Wars or Dutch Wars Four naval conflicts between  England and the Dutch Republic in the 17th�18th century. The First</p><p>(1652-54), Second (1665-67), and Third (1672-74) Anglo-Dutch Wars  all arose from commercial rivalry between the two nations, and victories  by England established its naval might.

The agreement led to the formation of the Triple  Entente.</p><p>Anglo-Saxon See Old English</p><p>Anglo-Saxon art Painting, sculpture, and architecture produced in  Britain from the late 5th century to the Norman Conquest. Before the 9th  century, manuscript illumination was the predominant art form, with two  schools: Canterbury produced works in the Classical tradition brought by  Roman missionaries; a more influential school in Northumbria produced  works inspired by the revival of learning encouraged by Irish missionar�  ies. The curvilinear forms, spirals, and interlaced patterns of the Celtic  tradition brought by Irish monks were integrated with the abstract orna�  mentation and bright colors of the Anglo-Saxon metalwork tradition. After  the destructive effects of the 9th-century Danish invasions, the monaster�  ies were revived and interest in architecture developed. Building activity  consisted of small churches influenced by continental types, notably from  Norman France (e.g., the original Westminster Abbey, c. 1045-50, rebuilt  1245). The monastic revival resulted in the production of many books  and the formation of the Winchester school of illumination (late 10th cen�  tury).

It was directly  influenced by early Scandinavian law as a result of the Viking invasions  of the 8th and 9th centuries and indirectly influenced (primarily through  the church) by Roman law. Anglo-Saxon law had three components: laws  promulgated by the king, customary practices such as those regulating  kinship relations, and private compilations. The primary emphasis was on  criminal law, though certain material dealt with problems of public admin�  istration, public order, and ecclesiastical matters.</p><p>Anglo-Saxon literature Literature written in Old English c. 650-c.  1100. Anglo-Saxon poetry survives almost entirely in four manuscripts.  Beowulf is the oldest surviving Germanic epic and the longest Old English  poem; other great works include The Wanderer, The Seafarer, The Battle  of Maldon, and the Dream of the Rood. The poetry is alliterative; one of  its features is the kenning, a metaphorical phrase used in place of a com�  mon noun (e.g., �swan road� for �sea�). Notable prose includes the Anglo-  Saxon Chronicle, a historical record begun about the time of King Alfred�s  reign (871-899) and continuing for more than three centuries.

Languages: Portu�  guese (official), indigenous languages.</p><p>Religions: Christianity (mostly Roman  Catholic; also Protestant); also traditional beliefs. Currency: kwanza. The  country contains several plateau regions, which separate it into three dis�  tinct drainage systems. One in the northeast drains into the Congo River  basin, and another in the southeastern sector drains into the Zambezi sys�  tem; the remaining drainage, westward into the Atlantic, provides most  of Angola�s hydroelectric power. About half of the land area is forest; less  than 10% is arable. Despite substantial petroleum reserves, Angola�s  economy has been unable to take advantage of its resources, because of  the devastation caused by protracted civil war. Angola is nominally a  republic with one legislative house; its head of state and government is  the president. An influx of Bantu-speaking peoples in the 1st millennium  ad led to their dominance in the area by c. 1500. The most important Bantu  kingdom was the Kongo; south of the Kongo was the Ndongo kingdom  of the Mbundu people. Portuguese explorers arrived in the early 1480s  and over time gradually extended their rule. Angola�s frontiers were  largely determined by other European powers in the 19th century but not  without strong resistance by the indigenous peoples. Resistance to colo�  nial rule led to the outbreak of fighting in 1961, which led ultimately to  independence in 1975. Rival factions continued fighting after indepen�  dence. Although a peace accord was reached in 1994, forces led by Jonas  M.

The label came from a press agent�s description  of John Osborne, whose play Look Back in Anger (1956) is the move�  ment�s representative work. The group includes John Wain (1925-1994),  Kingsley Amis, Alan Sillitoe, and Bernard Kops (b. 1926). A dominant lit�  erary force in the 1950s, the movement had faded by the early 1960s.</p><p>Angstrom Vaq-strcemX, Anders Jonas (b. Aug. 13, 1814, Logdo,  Swed.�d. June 21, 1874, Uppsala) Swedish physicist. From 1839 he  taught at the University of Uppsala. He devised a method of measuring  thermal conductivity, showing it to be proportional to electrical conduc�  tivity, and deduced that an incandescent gas emits rays of the same refran-  gibility as those it can absorb. A founder of spectroscopy, he discovered  that hydrogen is present in the Sun�s atmosphere, published a map of the  normal solar spectrum, and was the first to examine the spectrum of the  aurora borealis and to detect and measure the characteristic bright line in  its yellow-green region. The angstrom (1CT 10 m), a unit of length, was  named in his honour.</p><p>Anguilla \aq-'gwi-b\ Island (pop., 2001: 11,300), Leeward Islands, West  Indies. A dependent territory of the United Kingdom, it is the most north�  erly of the Leeward Islands and covers about 35 sq mi (90 sq km). Its  territory includes nearby Scrub, Seal, Dog, and Sombrero islands and  Prickly Pear Cays. Most of its people are descendants of African slaves.  The official language is English, and most of the population is Protestant.  First colonized in 1650 by settlers from Saint Kitts, it was administered  by the British. From 1825 it was closely associated with Saint Kitts, a  situation Anguilla protested. It was united with Saint Kitts and Nevis in  1882. When a nation consisting of the three was formed in 1967, Anguilla  proclaimed its independence. The British intervened, and Anguilla was  separated in 1980; while retaining some autonomy, it consented to remain  under British rule.</p><p>angular momentum Property that describes the rotary inertia of a  system in motion about an axis. It is a VECTOR quantity, having both mag�  nitude and direction. The magnitude of the angular momentum of an  object is the product of its linear momentum (mass m x velocity v) and the  perpendicular distance r from the centre of rotation, or mvr. The direc�  tion is that of the axis of rotation. The angular momentum of an isolated  system is constant. This means that a rigid spinning object continues to  spin at a constant rate unless acted upon by an external torque. A spin�  ning gyroscope in an airplane remains fixed in its orientation, independent  of the airplane�s motion, because of the conservation of direction as well  as magnitude.</p><p>Angus Breed of black, hornless beef cattle. Formerly known as Aber�  deen Angus, it originated in northeastern Scotland, but its ancestry is  obscure. Angus have a compact and low-set body. The fine quality of the  flesh and the high dressing percentage make it a beef breed of the high�  est rank. Introduced into the U.S. in 1873, its influence there and in other  countries spread widely thereafter.</p><p>Anhalt \'an-,halt\ Former German state in what is now central Germany.  The area around the upper Elbe River from which Anhalt was constituted  was, in the 11th century, still part of the duchy of Saxony. It achieved  separate territorial status in 1212. Subdivided and reunited frequently, it  was finally reconstituted as the duchy of Anhalt by Leopold IV in 1863.  It became part of the German Empire in 1871. Reconstituted after World  War II as Saxony-Anhalt, it subsequently became part of East Germany  and, in 1990, part of reunified Germany.</p><p>Anheuser Van-hoi-zorV -Busch Co., Inc. One of the largest produc�  ers of beer in the world.

In 1876 the  company introduced a light-coloured beer called Budweiser; under August  Anheuser Busch, Jr. (president 1946-75), and August A. Busch III (1975�  2002), it became the best-selling U.S. beer brand. The company also pro�  duces the Michelob brand. Among its other holdings are beverage-  container manufacturing and recycling plants, media and advertising  groups, and amusement parks, including the SeaWorld theme parks and  Busch Gardens (Tampa, Fla.).</p><p>anhinga or snakebird Any fish-eating bird of the family Anhingidae  (order Pelecaniformes), sometimes considered a single species (Anhinga  anhinga) with geographical variants. Anhingas are about 35 in. (90 cm)  long, slender, and long-necked. They are mostly black, with silvery wing  markings. Males, glossed with green, develop pale head plumes and a dark  �mane� in breeding season. Anhingas live in small colonies along lakes  and rivers in tropical to warm temperate regions except in Europe. They  swim nearly submerged; the head and neck show above water, darting  snakelike from side to side.</p><p>Anhui or An-hui conventional Anhwei \'an-'hwa\ Province (pop.,  2002 est.: 63,380,000), east-central China. It is bounded by Jiangsu, Zhe�  jiang, Jiangxi, Hubei, Shandong, and Henan provinces. With an area of  54,000 sq mi (139,900 sq km), it is one of China�s smallest provinces;  its capital is Hefei. Anhui was the first part of southern China to be settled  by the Han dynasty, from c. 205 bc. Well-watered by the Huai and Yangtze  (Chang) rivers, it was the empire�s major agricultural area for several  centuries. Anhui was ruled by the Ming dynasty in the 14th-17th centu�  ries. It was occupied by the Japanese in World War II; after the war the  Nationalists held it briefly before the communists took over. It remains a  notable agricultural producer.</p><p>anhydride \,an- , hl- l drid\ Any chemical compound obtained, either in  practice or in principle, by eliminating water (H 2 0) from another com�  pound. Examples of inorganic anhydrides are sulfur trioxide, S0 3 , which  is derived from sulfuric acid, H 2 S0 4 , and calcium oxide, CaO, which is  derived from calcium hydroxide Ca(OH) 2 . The most important organic  anhydride is acetic anhydride, (CH 3 C0) 2 0, a raw material for making  cellulose acetate (used for films, fibres, and plastic goods) and aspirin. It  can be thought of as acetic acid minus water. Organic anhydrides are very  important starting materials for organic synthesis, as they can give rise to  carboxylic acids, esters, or amides under the proper conditions.</p><p>anhydrite Rock-forming mineral, anhydrous calcium sulfate (CaS0 4 ),  which differs chemically from gypsum (to which it changes in humid  conditions) by having no water of crystallization. Anhydrite occurs most  often with salt deposits in association with gypsum, as in the cap rock of  the Texas-Louisiana salt domes. Anhydrite is one of the major minerals  in evaporite deposits; it is also present in dolomites and limestones, and  in ore veins. It is used in plasters and cement as a drying agent.</p><p>Aniakchak \,an-e-'ak-chak\ National Monument and Pre�  serve Park, southern shore of the Alaska Peninsula, U.S. Situated in the  volcanically active Aleutian Range, it consists primarily of a great dry  caldera, which last erupted in 1931. The crater has an average diameter  of 6 mi (10 km). Declared a national monument in 1978, it covers 942  sq mi (2,440 sq km).</p><p>Aniene River \an-'ya-na\ River, central Italy. It rises in the Simbruini  Mountains southeast of Rome and meanders 67 mi (108 km) to join the  Tiber River north of Rome. Nero created a group of artificial lakes in its  upper course and built a villa there, the remains of which survive.</p><p>aniline Va-no-.lInN One of the most important organic bases, parent sub�  stance for many dyes and drugs. Pure aniline is a highly poisonous, oily,  colourless liquid with a distinctive odour. First obtained (1826) from  indigo, it is now prepared synthetically. It is a weakly basic primary aro�  matic amine and participates in many reactions with other compounds. It  is used to make chemicals used in producing rubber, dyes and interme�  diates, photographic chemicals, urethane foams, pharmaceuticals, explo�  sives, herbicides, and fungicides as well as to make chemicals used in  petroleum refining.</p><p>animal Any member of the kingdom Animalia (see taxonomy), a group  of many-celled organisms that differ from members of the two other  many-celled kingdoms, the plants and the fungi (see fungus), in several  ways. Animals have developed muscles, making them capable of spon�  taneous movement (see locomotion), more elaborate sensory and nervous</p><p>systems, and greater levels of general complexity. Unlike plants, animals  cannot manufacture their own food, and thus are adapted for securing and  digesting food. In animals, the cell wall is either absent or composed of  material different from that of the plant cell wall. Animals account for  about three-quarters of living species. Some one-celled organisms display  both plant and animal characteristics. See also algae, arthropod, bacteria,  CHORDATE, INVERTEBRATE, PROTIST, PROTOZOAN, VERTEBRATE.</p><p>animal communication Transmission of information from one ani�  mal to another by means of sound, visible sign or behaviour, taste or  odour, electrical impulse, touch, or a combination of these. Most animal  communication uses sound (e.g., birds calling, crickets chirping). Visual  communication usually indicates an animal�s identity (species, sex, age,  etc.) or other information through specific characteristics (e.g., horns,  patches of colour) or behaviour (e.g., the bee�s �dance� describing a  source of food). Chemical communication involves pheromones (chemi�  cal signals) produced by the animal�s endocrine system. Eels and some  other fishes use electrical impulses to communicate.</p><p>animal husbandry Controlled cultivation, management, and produc�  tion of domestic animals, including improvement of the qualities consid�  ered desirable by humans by means of breeding. Animals are bred and  raised for utility (e.g., food, fur), sport, pleasure, and research. See also  BEEKEEPING, DAIRY FARMING.</p><p>animal rights rights, primarily against being killed and being treated  cruelly, that are thought to be possessed by higher nonhuman animals  (e.g., chimpanzees) and many lower ones by virtue of their sentience.  Respect for the welfare of animals is a precept of some ancient Eastern  religions, including Jainism, which enjoins ahimsa (�noninjury�) toward  all living things, and Buddhism, which forbids the needless killing of ani�  mals, especially (in India) of cows. In the West, traditional Judaism and  Christianity taught that animals were created by God for human use,  including as food, and many Christian thinkers argued that humans had  no moral duties of any kind to animals, even the duty not to treat them  cruelly, because they lacked rationality or because they were not, like  Man, made in the image of God. This view prevailed until the late 18th  century, when ethical philosophers such as Jeremy Bentham applied the  principles of utilitarianism to infer a moral duty not to inflict needless suf�  fering on animals. In the latter half of the 20th century, the ethical phi�  losopher Peter Singer and others attempted to show that a duty not to harm  animals follows straightforwardly from simple and widely accepted moral  principles, such as �It is wrong to cause unnecessary suffering.� They also  argued that there is no �morally relevant difference� between humans and  animals that would justify raising animals, but not humans, for food on  �factory farms� or using them in scientific experiments or for product  testing (e.g., of cosmetics). An opposing view held that humans have no  moral duties to animals because animals are incapable of entering into a  hypothetical �moral contract� to respect the interests of other rational  beings. The modern animal-rights movement was inspired in part by Sing�  er�s work. At the end of the 20th century, it had spawned a large number  of groups dedicated to a variety of related causes, including protecting  endangered species, protesting against painful or brutal methods of trap�  ping and killing animals (e.g., for furs), preventing the use of animals in  laboratory research, and promoting what adherents considered the health  benefits and moral virtues of vegetarianism.</p><p>animals, cruelty to Willful or wanton infliction of pain, suffering, or  death upon an animal or the intentional or malicious neglect of an ani�  mal. Perhaps the world�s first anticruelty law, which addressed the treat�  ment of domesticated animals, was included in the legal code of the  Massachusetts Bay Colony (1641); similar legislation was passed in Brit�  ain in 1822. The world�s first animal welfare society, the Society for the  Protection of Animals, was established in England in 1824; the American  Society for the Prevention of Cruelty to Animals was chartered in 1866.  In varying degrees, cruelty to animals is illegal in most countries, and  interest in endangered species gave further impetus to the anticruelty move�  ment in the late 20th century. Reflecting such interest, many laws have  been passed, though they are seldom enforced unless public pressure is  brought to bear. Acts targeted by the movement have ranged from the  mistreatment of domesticated animals to bullfighting and vivisection. Fac�  tory farming, which involves various evidently cruel practices, has  remained largely exempt from legal scrutiny.

He requires that  hunters treat slain animals with respect; if they fail to do so, he may with�  hold game until he is placated through a ceremony or by a shaman.</p><p>animation Process of giving the illusion of movement to drawings,  models, or inanimate objects. From the mid-1850s, such optical devices  as the zoetrope produced the illusion of animation. Stop-action photog�  raphy enabled the production of cartoon films. The innovative design and  assembly techniques of Walt Disney soon moved him to the forefront of  the animation industry, and he produced a series of classic animated films,  beginning with Snow White and the Seven Dwarfs (1937). The Fleischer  brothers and the animators at Warner Brothers offered more irreverent  cartoons that often appealed to adult audiences. In Europe new animation  alternatives to line drawing were developed, including animation using  puppets (sometimes made from clay). In the late 20th century computer  animation, as seen in the first fully computer-generated animated feature,  Toy Story (1995), moved the art to a new level.</p><p>anime Style of animation popular in Japanese films. Anime films are  meant primarily for the Japanese market and, as such, employ many cul�  tural references unique to Japan. For example, the large eyes of anime  characters are commonly perceived in Japan as multifaceted �windows to  the soul.� Much of the genre is aimed at the children�s market, but anime  films are sometimes marked by adult themes and subject matter. Modern  anime began in 1956 and found lasting success in 1961 with the estab�  lishment of Mushi Productions by Osamu Tezuka, a leading figure in  modern manga (Japanese comics). Such anime as Akira (1988), Princess  Mononoke (1997), and the Pokemon series of films have attained inter�  national popularity.</p><p>animism Belief in the existence of spirits separable from bodies. Such  beliefs are traditionally identified with small-scale (�primitive�) societies,  though they also occur in major world religions. They were first compe�  tently surveyed by Edward Burnett Tylor in Primitive Culture (1871). Clas�  sic animism, according to Tylor, consists of attributing conscious life to  natural objects or phenomena, a practice that eventually gave rise to the  notion of a soul.

Native to  Egypt and the eastern Mediterranean region, anise is cultivated through�  out the world. Aniseed is used as a flavouring and as a soothing herbal  tea. Star anise is the dried fruit of the evergreen tree Illicium verum (mag�  nolia family), native to southeastern China and Vietnam. Its flavour and  uses are similar to those of anise.</p><p>Anjou \'an-jii\ Historical region, lower Loire valley, northwestern France.  Organized in the Gallo-Roman period as the Civitas Andegavensis, it later  became the countship, and from 1360 the duchy, of Anjou. Its capital was  Angers. Under the Carolingian dynasty, it was nominally administered by  a count representing the French king. The area came under the English  king Henry II when he married Eleanor of Aquitaine in 1152, thus found�  ing the Anglo-Angevin empire of the Plantagenet dynasty. The French  recovered Anjou in 1259, and it was united with France in 1487. It ceased  to exist as a department in 1790.</p><p>Anjou, House of See House of Plantagenet</p><p>Ankara Vaq-ko-roV formerly Angora City (pop., 1997: 2,984,099),  capital of Turkey. Located about 125 mi (200 km) south of the Black Sea,  it has been inhabited at least since the Stone Age. Conquered by Alex�  ander the Great in 334 bc, it was incorporated into the Roman Empire by  Augustus. As a city of the Byzantine Empire, Ankara fell to the Turks in  1073, but the Crusader Raymond IV of Toulouse drove them out in 1101.  In 1403 it came under the rule of the Ottoman Empire. After World War I  (1914-18) Mustafa Kemal AtatOrk made Ankara the centre of resistance to  both the Ottomans and the invading Greeks, and it became the capital of  the Republic of Turkey in 1923. The modern city is the country�s chief</p><p>industrial centre after Istanbul.

Gloucester and Rockport are its main towns.</p><p>Ann Arbor City (pop., 2000: 114,024), southeastern Michigan, U.S.  Founded in 1824, it became an agricultural centre with the coming of the  railroad in 1839. The University of Michigan, which moved there from  Detroit in 1837, has played a major role in Ann Arbor�s growth. Private  industrial research and the university�s institutes of science and technol�  ogy make the city a major Midwest centre for space and nuclear research.</p><p>Anna (Ivanovna) (b. Jan. 28, 1693, Moscow, Russia�d. Oct. 17,  1740, St. Petersburg) Empress of Russia (1730^40). After the death of  Peter II, the Supreme Privy Council, Russia�s actual ruling body, offered  Anna the throne (as the daughter of Ivan V) if she agreed to conditions  placing the real power in the council�s hands. She initially agreed but later  tore up the conditions, abolished the council, and reestablished the autoc�  racy, countenancing a severely repressive regime. She occupied herself  primarily with extravagant amusements and relied on her lover, Ernst  Johann Biron (1690-1772), and a group of German advisers to manage  the state. Shortly before her death, Anna named as her successor her  grand-nephew Ivan (later Ivan VI).</p><p>Anna Comnena \kam-'ne-n9\ (b. Dec. 2, 1083�d. c. 1153) Byzan�  tine historian.

Identified with the port of ancient Hippo  (or Hippo Regius), it was a rich city of Roman Africa. It was home to St.  Augustine 396-430. Severely damaged by the Vandals in 431, it passed  to the Byzantine Empire in 533 before being overrun by the Arabs in the 7th  century and named Bona. It was occupied by the French in 1832 when  they conquered Algeria. Modern Annaba is Algeria�s chief exporter of  minerals; it also serves as a trading port and port of call.</p><p>Annales \a-'nal\ school School of history. Established by Lucien Feb-  vre (1878-1956) and Marc Bloch (1886-1944), its roots were in the jour�  nal Annales: economies, societes, civilisations, Febvre�s reconstituted  version of a journal he had earlier formed with Marc Bloch. Under  Fernand Braudel�s direction the Annales school promoted a new form of  history, replacing the study of leaders with the lives of ordinary people  and replacing examination of politics, diplomacy, and wars with inquir�  ies into climate, demography, agriculture, commerce, technology, trans�  portation, and communication, as well as social groups and mentalities.  While aiming at a �total history,� it also yielded dazzling microstudies of  villages and regions. Its international influence on historiography has been  enormous.</p><p>Annam \a-'nam\ Historic kingdom, central Vietnam. The area was con�  quered c. 200 bc by the Chinese, who gave it its name (which has never</p><p>The Ataturk Mausoleum, Ankara, Tur�  key.</p><p>ROBERT HARDING PICTURE LIBRARY</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Annan &#x25BA; annuity I 77</p><p>been used by the indigenous inhabitants). It became independent in the  15th century ad, opening the way for steady Vietnamese movement  toward the Mekong River delta. When Vietnam was united in 1802, the  city of Hue became the capital, and the area was ruled by the emperor of  Annam. Central Vietnam gradually came under French control in the 19th  century; it became a protectorate in 1883-85, leaving the court at Hue  with only nominal power. The area was partitioned between North and  South Vietnam in 1954; Annam�s last emperor had abdicated in 1945 but  served as Vietnam�s chief of state from 1949 until shortly after partition.</p><p>Annan \a-'nan\, Kofi (Atta) (b. April 8, 1938, Kumasi, Gold Coast)  Seventh secretary-general of the United Nations (from 1997), who shared,  with the UN, the 2001 Nobel Prize for Peace. He was the son of a pro�  vincial governor and hereditary paramount chief of the Fante people. He  did graduate work at Geneva�s Institute for Advanced International Stud�  ies and at MIT. He has spent almost his entire career within the UN,  beginning at the World Health Organization (1962). As undersecretary-  general for peacekeeping (from 1993), he transferred peacekeeping opera�  tions in Bosnia from the UN to NATO. Elected in Decemberl996, he  became the first UN secretary-general from sub-Saharan Africa, and he  enjoyed a mandate to reform the UN bureaucracy. He criticized the UN�s  failure to prevent or minimize genocide in Rwanda (1994) and unsettled  many by declaring that the UN should address human-rights violations  perpetrated by governments against their own people. His priorities  included reforming the UN, restoring public confidence in the organiza�  tion, and strengthening the UN�s activities for peace and development.  Annan was appointed to a second term in 2001.</p><p>Annapolis \3-'na-p3-l9s\ City (pop., 2000: 35,838), capital of Mary�  land, U.S. It lies along the Severn River on Chesapeake Bay. Settled in 1649  as Providence by Virginia Puritans, it was later known as Town Land at  Proctor�s and Ann Arundel Town. It became the colonial capital in 1694  and was later renamed to honour Princess (later Queen) Anne. Its  economy is tied to government services, and it is home to the U.S. Naval  Academy.</p><p>Annapolis Convention (September 1786) Meeting in Annapolis,  Md., U.S., that caused the convening of the Constitutional Convention.

It forms a ridge 30 mi (48 km)  long and contains four main summits. Annapurna I (26,545 ft, or 8,091 m)  was first scaled in 1950 by a French expedition; it was the first peak of  more than 26,000 ft (8,000 m) to be ascended to the summit. In 1970 an  all-woman Japanese team climbed Annapurna III (24,786 ft, or 7,555 m).</p><p>Anne (b. Feb. 6, 1665, London, Eng.�d. Aug. 1, 1714, London) Queen  of Great Britain (1702-14) and the last Stuart monarch. Second daughter  of James II, who was overthrown by William III in 1688, Anne became queen  on William�s death (1702). Though she wished to rule independently, her  intellectual limitations and poor health led her to rely on advisers, includ�  ing the duke of Marlborough. Her reign was marked by the Act of Union  with Scotland (1707) and by bitter rivalries between Whigs and Tories.  Because she never gave birth to a successor, the regency passed to the  Hanoverian descendants of James I.</p><p>Anne Boleyn \bu-'lin\ (b. 1507?�d. May 19, 1536, London, Eng.)  British royal consort. After spending part of her childhood in France, Anne  lived at the court of Henry VIII, who soon fell in love with her and began  secret proceedings to rid himself of his first wife, Catherine of Aragon. For  six years Pope Clement VII refused to grant an annulment. In 1533 Henry  and Anne were secretly married, and Henry had the archbishop of Canter�  bury, Thomas Cranmer, annul his previous marriage. Anne gave birth to  the future Elizabeth I but failed to produce the male heir Henry wanted. He  lost interest in her, and in 1536 he had her imprisoned on questionable  charges of adultery and incest. She was convicted and beheaded.</p><p>Anne of Austria (b. Sept. 22, 1601, Valladolid, Spain�d. Jan. 20,  1666, Paris, France) Queen consort (1615-43) of Louis XIII of France and  regent (1643-51) for her son Louis XIV. Daughter of Philip III of Spain and  Margaret of Austria, Anne married the 14-year-old Louis XIII in 1615.  He treated her coolly, and the powerful cardinal de Richelieu attempted to  limit her influence over her husband. After Louis XIII died and she was  declared sole regent, she strove to ensure that her son would succeed to</p><p>the absolute power Richelieu had  won for Louis XIII. Together with  her first minister, Cardinal Mazarin,  she faced the series of revolts known  as the Fronde.

Henry married Anne, whom he  found homely, to form an alliance with her brother William, duke of  Cleves, a leader of the Protestants of western Germany. The alliance,  arranged by Thomas Cromwell, seemed necessary because it appeared that  the major Roman Catholic powers, France and the Holy Roman Empire,  intended to attack Protestant England. When that threat dissipated, the  marriage became a political embarrassment and was annulled by an Angli�  can convocation in 1540.</p><p>annealing Treatment of a metal, alloy, or other material by heating to  a predetermined temperature, holding for a certain time, and then cool�  ing to room temperature, done to improve ductility and reduce brittleness.  Process annealing is carried out intermittently during the working of a  piece of metal to restore ductility lost through repeated hammering or  other working, if several cold-forming operations are required but the  metal is so hardened after the first operation that further cold working  would cause cracking (see hardening). Full annealing is done to give  workability to such parts as forged blanks destined for use in the machine-  tool industry. Annealing is also done for relief of internal stresses in metal  and glass. Annealing temperatures and times differ for different materials  and with properties desired; steel is usually held for several hours at about  1,260�F (680�C) and then cooled for several hours.

It announces the invalid�  ity of a marriage that was void from its inception. It is to be distinguished  from dissolution or divorce. To justify annulment, the marriage contract  must have a defect (e.g., incompetence of one party because of age, insan�  ity, or a preexisting marriage). Continued absence of one party may also  justify annulment. Generally, annulment is easier if the marriage is uncon�  summated. Both secular law and Christian canon law have annulment  procedures.</p><p>anode Terminal or electrode from which electrons leave a system. In a  battery or other source of direct current, the anode is the negative termi�  nal. In a passive load it is the positive terminal. In an electron tube, elec�  trons from the cathode travel across the tube toward the anode; in an  electroplating cell, negative ions are deposited at the anode.</p><p>anodizing Method of coating metal for corrosion resistance, electrical  insulation, thermal control, abrasion resistance, sealing, improving paint  adhesion, and decorative finishing. Anodizing consists of electrically  depositing an oxide film from aqueous solution onto the surface of a metal,  often aluminum, which serves as the anode in an electrolytic cell. In the  most common type of anodizing, which uses a 15% sulfuric acid bath,  dyes can be introduced into the oxidation process to achieve a coloured  surface. Aluminum thus anodized and coloured is used widely in giftware,  home appliances, and architectural decoration.</p><p>anomie Va-no-meX In the social sciences, a condition of social instabil�  ity or personal unrest resulting from a breakdown of standards and val�  ues or from a lack of purpose or ideals. The term was introduced in 1897</p><p>by Emile Durkheim, who believed that one type of suicide (anomic) resulted  from the breakdown of social standards that people need and use to regu�  late their behavior. Robert K. Merton studied the causes of anomie in the  U.S., finding it severest in persons who lack acceptable means of achiev�  ing their cultural goals. Delinquency, crime, and suicide are often reac�  tions to anomie.

Anorexia nervosa typi�  cally begins in late adolescence. In women a usual symptom is amenor�  rhea. A person with anorexia nervosa will often go to great lengths to resist  eating in order to lose weight, and medical complications can be life-  threatening. Treatment can include psychological and social therapy.</p><p>anorthite Feldspar mineral, calcium aluminosilicate (CaAl 2 Si 2 0 8 ), that  occurs as white or grayish, brittle, glassy crystals.

The Ermine (1932), followed by  the successful Traveler Without Luggage (1937). He is best remembered  for Antigone (1944), The Lark{ 1953), and Becket (1959), in which he used  techniques such as the play within the play, flashbacks and flash-forwards,  and the exchange of roles. A skillful exponent of the well-made play, he  rejected naturalism and realism in favour of a return to theatricausm.</p><p>Ansar Arabic "Helper" Term originally applied to some of the Com�  panions of the Prophet. When Muhammad left Mecca for Medina, the Ansar  were the Medinese who aided him and who became his devoted follow�  ers, serving in his army.

In  1938 the Austrian chancellor Kurt von Schuschnigg was bullied into can�  celing a plebiscite on union with Germany, which he expected Austrians  to oppose. He resigned his office and ordered the Austrian army not to  resist the Germans. The Germans invaded on March 12, and the enthu�  siasm shown by Austrians persuaded Hitler to annex Austria outright the  next day. Though France and Britain protested Hitler�s methods, they and  other countries accepted the fait accompli.</p><p>Anselm of Canterbury, Saint (b. 1033/34, Aosta, Lombardy�d.  April 21, 1109, possibly at Canterbury, Kent, Eng.; feast day April 21)  Founder of Scholasticism. Anselm entered the Benedictine monastery at  Bee (in Normandy) in 1057 and became abbot in 1078. In 1077 he wrote  the Monologium to demonstrate God�s existence and attributes by reason  alone. He then wrote Proslogium, which established the ontological argu�  ment for the existence of God. In 1093, he became archbishop of Canter�  bury and soon became involved in disputes with William II over the  independence of the church and the right to appeal to the pope, arguments  that led to Anselm�s exile. Although invited back by Henry I, Anselm again  argued with the king over lay investiture (see Investiture Controversy). In  1099 he completed Cur Deus homo? (�Why Did God Become Man?�),  which provided a new understanding of Jesus� redemption of humankind  and revealed the increasing focus on the humanity of Jesus. Anselm was  declared a Doctor of the Church in 1720.</p><p>Ansgar \'ans-,gar. Saint (b. probably 801, near Corbie, Austrasia�d.

It was destroyed by fire during  the Boxer Rebellion and badly damaged during the Russo-Japanese War  (1904-05). In the 1930s the Japanese occupied Anshan and made it a steel�  making centre. The city was bombed by U.S. aircraft in 1944 and looted  by the Soviets following World War II. The Chinese later redeveloped it  into an industrial centre that produces steel, cement, and chemicals.</p><p>ant Any member of approximately 8,000 species of the social insect  family Formicidae. Ants are found  worldwide but are especially com�  mon in hot climates. They range  from 0.1 to 1 in. (2-25 mm) long and  are usually yellow, brown, red, or  black. Ants eat both plant and animal  substances; some even �farm� fungi  for food, cultivating them in their  nests, or �milk� aphids. Ant colonies  consist of three castes (queens,  males, and workers, including sol�  diers) interacting in a highly com�  plex society paralleling that of the  honeybees.

The waters around Antarctica are sometimes  called the Southern Ocean; however, the term �Antarctic Ocean� is some�  times also used, inappropriately. Much of the area is characterized by  subpolar conditions, and ice shelves and sea ice extend well beyond the  borders of the continent. Water cooled by the coastal ice masses of the  Antarctic continent sinks and flows northward along the ocean bottom and  is replaced at the surface by warmer water flowing south from the Indian,  Pacific, and Atlantic oceans. The meeting point of these currents is the  Antarctic Convergence, an area rich in phytoplankton and krill, which are  important to various species of fish as well as to penguins and seabirds.</p><p>Antarctica Fifth largest continent on Earth.

The southern portions of  the Atlantic, Pacific, and Indian oceans  surround it (see Antarctic regions). Antarc�  tica would be circular except for the outflaring Antarctic Peninsula and  two principal bays, the Ross Sea and the Weddell Sea. East and West Ant�  arctica are separated by the long chain (1,900 mi [3,000 km]) of the Tran-  santarctic Mountains. The ice sheet overlaying the continent represents  about 90% of the world�s glacial ice. By far the coldest continent, it has  the world�s lowest recorded temperature, -128.6 �F (-89.2 �C), measured  in 1983. The climate supports only a small community of land plants, but  the rich offshore food supply sustains penguins and immense seabird  rookeries. There are no permanent human inhabitants. The Russian F.G.  von Bellingshausen (b. 1778�d. 1852), the Englishman Edward Brans-  field (b. 1795?�d. 1852), and the American Nathaniel Palmer (b.  1799�d. 1877) all claimed first sightings of the continent in 1820. The  period to c. 1900 was dominated by the exploration of Antarctic and sub-  Antarctic seas. The early 20th century, the �heroic era� of Antarctic explo�  ration, produced expeditions deep into the interior by Robert Falcon Scott  and later Ernest Shackleton. The South Pole was reached by Roald Amund�  sen in December 1911 and by Scott in January 1912. The first half of the  20th century was also Antarctica�s colonial period. Seven nations claimed  sectors of the continent, while many other nations carried out explora�  tions. In the International Geophysical Year of 1957-58, 12 nations estab�  lished over 50 stations on the continent for cooperative study. In 1961 the  Antarctic Treaty, reserving Antarctica for free and nonpolitical scientific  study, entered into full force.

Their mouth opening is small, and the tongue is  long and wormlike. They live alone or in pairs and feed mainly on ants  and termites, which they obtain by inserting their sticky tongue into a nest  torn open by the long, sharp, curved claws of their forefeet. The species  range in length from 15 in. (37 cm) to 6 ft (1.8 m).

He prob�  ably belonged to the Magistri Antelami, a civic builders� guild in the Lake  Como region. An early signed marble relief by him, The Descent from the  Cross (1178), is in Parma Cathedral; his extensive cycle of sculpture on  the baptistery at Parma was begun in 1196. He is credited with the sculp�  tural decorations of Fidenza Cathedral and Ferrara Cathedral. His last  work is believed to have been the decoration and (at least in part) the  construction of the church of Sant�Andrea at Vercelli, the architecture of  which successfully combined Tuscan Romesque with Gothic characteris�  tics (such as flying buttresses, rose windows, and ribbed vaulting) and  won him lasting renown.</p><p>antelope Any of numerous species of Old World grazing or browsing  bovids that typically are swift, slender, and graceful plains dwellers. The  North American pronghorn is also sometimes referred to as an antelope.  Most antelope are African; the others, except for the pronghorn, are Eur�  asian. They range in shoulder height from 10 to 70 in. (25-175 cm). The  male, and sometimes the female, bears distinctive, backwardly curved  horns.

Antennae of insects, which are movable, are believed to serve as  both tactual and smell receptors; in some species, the development of  elaborate antennal plumes and brushlike terminations has led to the sug�  gestion that they also serve for hearing. Evidence supports this idea only  for the mosquito, whose antennae are attached to specialized structures  stimulated by vibrations of the antennal shaft. In social insects (e.g., ants),  antennae movements may serve as communication.</p><p>Antenor \an-'te-nor\ (fl. c. 530-510 bc) Greek sculptor active in Athens.  In antiquity he was famous for his bronze group of the Tyrannicides (c.  510 bc) made for the Athenian agora; the statues no longer exist. There  were elements of motion and accurate anatomical detail in the work that  mark the transition between the Archaic and Classical eras.

Feb. 15, 1820, Adams, Mass.,  U.S.�d. March 13, 1906, Rochester, N.Y.) U.S. pioneer in the women's  suffrage movement. A precocious child, she learned to read and write at the</p><p>age of three. After attending a board�  ing school in Philadelphia, she took  a teaching position in a Quaker semi�  nary in upstate New York. She taught  at a female academy (1846-49) and  then settled in her family home near  Rochester, N.Y. There she met many  leading abolitionists, including Fred�  erick Douglass and William Lloyd Gar�  rison. The rebuff of her attempt to  speak at a temperance meeting in  Albany in 1852 prompted her to join  Elizabeth Cady Stanton in organizing  the Woman�s State Temperance  Society of New York. From this time  she was a tireless campaigner for  abolition and women�s rights. Dur�  ing the early phase of the Civil War  she helped organize the Women�s  National Loyal League, which urged  the case for emancipation. After the  war, she campaigned unsuccessfully to have the language of the Four�  teenth Amendment altered to allow for woman as well as �Negro� suf�  frage. In 1868 she represented the Working Women�s Association of New  York, which she had recently organized, at the National Labor Union  convention. In January 1869 she organized a woman suffrage convention  in Washington, D.C., and in May she and Stanton formed the National  Woman Suffrage Association (NWSA). As a test of the legality of the suf�  frage provision of the Fourteenth Amendment, she cast a vote in the 1872  presidential election in Rochester. She was arrested, convicted (the  judge�s directed verdict of guilty had been written before the trial began),  and fined; though she refused to pay the fine, the case was carried no  further. She served as president of the National American Woman Suf�  frage Association (1892-1900) and lectured throughout the country for a  federal women�s-suffrage amendment.</p><p>Anthony of Egypt, Saint (b. 251, Koma, near al-Minya, Heptano-  mis, Egypt�d.

He began his practice of asceticism at  age 20 and lived in solitude on Mount Pispir from 286 to 305. He emerged  from his retreat to organize the monastic life of the hermits who had  settled nearby. When the Edict of Milan (313) ended the persecution of  Christians, Anthony moved to the desert between the Nile and the Red  Sea. His monastic rule was compiled from writings and discourses attrib�  uted to him in Athanasius�s Life of St. Anthony and the Apophthegmata  patrum and was still observed in the 20th century by Coptic and Arme�  nian monks.

A dis�  ease chiefly of herbivores, the infection may be acquired by persons han�  dling the wool, hair, hides, bones, or carcasses of affected animals.  Infection may lead to death from respiratory or cardiac complications  (within 1-2 days if acute), or the animal may recover. In humans, anthrax  occurs as a cutaneous, pulmonary, or intestinal infection. The most com�  mon type, which occurs as an infection of the skin, may lead to fatal sep�  ticemia (blood poisoning). The pulmonary form of the disease is usually  fatal. Sanitary working environments for susceptible workers are critical  to preventing anthrax; early diagnosis and treatment are also of great  importance. In recent decades, various countries have attempted to  develop anthrax as a weapon of biological warfare; many factors, includ�  ing its extreme potency (vastly greater than any chemical-warfare agent),  make it the preferred biological-warfare agent. Concerns about anthrax  mounted in 2001 after it was found in letters mailed to members of the  U.S. government and news agencies.</p><p>anthropology The �study of humanity.� Anthropologists study human  beings in aspects ranging from the biology and evolutionary history of  Homo sapiens to the features of society and culture that decisively dis�  tinguish humans from other animal species.

Physi�  cal anthropology is the branch that concentrates on the biology and evo�  lution of humanity. The branches that study the social and cultural  constructions of human groups are variously recognized as belonging to  cultural anthropology (or ethnology), social anthropology, linguistic  anthropology, and psychological anthropology. Archaeology, as the  method of investigation of prehistoric cultures, has been an integral part  of anthropology since it became a self-conscious discipline in the latter  half of the 19th century.</p><p>anthroposophy V.an-thro-'pa-so-foV Philosophy based on the view that  the human intellect has the ability to contact spiritual worlds. It was for�  mulated in the early 20th century by Rudolf Steiner and was influenced by  theosophy. Steiner wanted to develop a faculty for spiritual perception  independent of the senses, which he believed was latent in all human  beings, and to this end he founded the Anthroposophical Society in 1912.  Now based in Dornach, Switzerland, the society has branches worldwide.</p><p>anthurium \an-'thur-e-3m\ Any plant of the genus Anthurium, com�  prising about 600 tropical herbaceous species in the arum family, many of  which are popular foliage plants. A few species are widely grown for the  florist trade for their showy, long-lasting blossoms; these include the fla�  mingo lily {A. andraeanum ), which boasts a salmon-red flower, and the  flamingo flower, or pigtail plant (A. scherzeranum), which has a scarlet  flower.</p><p>Anti-Comintern Pact Agreement concluded first between Germany  and Japan (Nov. 25, 1936) and later between Italy, Germany, and Japan  (Nov. 6, 1937). The pact, sought by Adolf Hitler, was ostensibly directed  against the Comintern but was specifically directed against the Soviet  Union. It was one of a series of agreements leading to the formation of  the Axis Powers. Japan renounced the pact in 1939 but later acceded to the  Tripartite Pact of 1940, which pledged Germany, Japan, and Italy to  mutual assistance.</p><p>Anti-Corn Law League British organization founded in 1839,  devoted to fighting England�s Corn Laws, regulations governing the  import and export of grain. It was led by Richard Cobden, who saw the  laws as both morally wrong and economically damaging. The league</p><p>mobilized the industrial middle classes against the landlords, and Cobden  won over the prime minister, Sir Robert Peel. The Corn Laws were repealed  in 1846.</p><p>Anti-Federalists U.S. leaders who opposed the strong central govern�  ment envisioned in the Constitution of the United States of 1787. Their  agitation led to the creation of the Bill of Rights. While admitting the need  for changes in the Articles of Confederation, they feared that a strong fed�  eral government would infringe on states' rights. The group�s adherents,  including George Mason, Patrick Henry, Thomas Paine, Samuel Adams, and  George Clinton, were as numerous as the members of the Federalist Party,  but their influence was weak in urban areas, and only Rhode Island and  North Carolina voted against ratification of the Constitution. Anti-  Federalists were powerful during the presidency of Thomas Jefferson,  when they formed the nucleus of what later became the Democratic Party.</p><p>Anti-Lebanon Mountains Mountain range along the border of Syria  and Lebanon. Running parallel to the Lebanon Mountains, the range aver�  ages 6,500 ft (2,000 m) in elevation. Because of its poor soil and steep  slopes, it is sparsely populated.</p><p>Anti-Masonic Movement Popular movement in the U.S. in the  1830s opposed to Freemasonry. The movement was ignited in 1826 by the  disappearance and presumed murder of a New York bricklayer and former  Mason, who had supposedly intended to reveal the order�s secrets. Reac�  tion against the Masons swept through the northeastern U.S. In 1831 the  Anti-Masonic Party became the first U.S. third party and the first party  to hold a national convention. It condemned Freemasonry for its secrecy  and undemocratic character. Its candidate won Vermont in the 1832 elec�  tion. By the late 1830s the Anti-Masonic movement had been absorbed  into the Whig Party.</p><p>anti-Semitism Hostility toward or discrimination against Jews as a  religious group or �race.� Although the term anti-Semitism has wide cur�  rency, it is regarded by some as a misnomer, implying discrimination  against all Semites, including Arabs and other peoples who are not the  targets of anti-Semitism as it is usually understood. In antiquity, hostility  to the Jews emerged because of religious differences, a situation wors�  ened as a result of the competition with Christianity. By the 4th century,  Christians tended to see Jews as an alien people whose repudiation of  Christ had condemned them to perpetual migration. Jews were denied  citizenship and its rights in much of Europe in the Middle Ages (though  some societies were more tolerant) or were forced to wear distinctive  clothing, and there were forced expulsions of Jews from several regions  in that period. Developed during the Middle Ages were many of the ste�  reotypes of Jews (e.g., the blood libel, alleged greed, conspiracy against  humankind) that have persisted into the modem era. The Enlightenment  and the French Revolution brought a new religious freedom to Europe in  the 18th century but did not reduce anti-Semitism, because Jews contin�  ued to be regarded as outsiders. In the 19th century violent discrimina�  tion intensified (see pogrom), and so-called �scientific racism� emerged,  which based hostility to the Jews on their supposed biological character�  istics and replaced religion as the primary basis for anti-Semitism. In the  20th century the economic and political dislocations caused by World War  I intensified anti-Semitism, and racist anti-Semitism flourished in Nazi  Germany. Nazi persecution of the Jews led to the Holocaust, in which an  estimated six million Jews were exterminated. Despite the defeat of the  Nazis in World War II, anti-Semitism remained a problem in many parts  of the world into the 21st century.</p><p>Anti-Slavery Society, American See American Anti-Slavery Society</p><p>antiaircraft gun Artillery piece fired from the ground or shipboard in  defense against aerial attack. They were first used in combat in World  War I, when field artillery were converted to antiaircraft use by mount�  ings that enabled them to fire nearly vertically. Range finders and search�  lights, developed in the 1920s and �30s, increased their effectiveness.  Advances in World War II included rapid-firing and automatic weapons,  radar for target tracking, and radio-operated fuses. British and U.S. forces  used a 40-mm gun that fired ammunition to a height of 2 mi (3.2 km).  Heavier guns, up to 120 mm, were used against high-flying bombers. For  most of the war, the most effective was the German 88-mm Fliegerabwe-  hrkanone\ its abbreviated name, flak, became a universal term for anti�  aircraft fire. With the introduction of guided missiles in the 1950s and �60s,  heavy antiaircraft guns were phased out, though lighter radar-guided auto�  matic guns remained effective against low-flying aircraft and helicopters.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>82 I antiballistic missile &#x25BA; Antigone</p><p>antiballistic missile (ABM) Weapon designed to intercept and  destroy ballistic missiles. Effective ABM systems have been sought since  the Cold War, when the nuclear arms race raised the spectre of complete  destruction by unstoppable ballistic missiles. In the late 1960s both the  U.S. and the Soviet Union developed nuclear-armed ABM systems that  combined a high-altitude interceptor missile (the U.S. Spartan and Soviet  Galosh) with a terminal-phase interceptor (the U.S. Sprint and Soviet  Gazelle). Both sides were limited by the 1972 Treaty on Antiballistic  Missile Systems to one ABM location each; the U.S. dismantled its sys�  tem, while the Soviet Union deployed one around Moscow. During the  1980s the U.S. began research on an ambitious Strategic Defense Initiative  against an all-out Soviet attack, but this effort proved expensive and tech�  nically difficult, and it lost urgency with the collapse of the Soviet Union.  Attention shifted to �theatre� systems such as the U.S. Patriot missile,  which was used with limited effect against conventionally armed Iraqi  Scud missiles during the Persian Gulf War (1990-91). In 2002 the U.S.  formally withdrew from the ABM treaty in order to develop a defense  against limited missile attack by smaller powers or �rogue� states.</p><p>Antibes \a n -'teb\ ancient Antipolis Seaport (pop., 1999: 72,412),  southeastern France. Located on the Mediterranean coast southwest of  Nice, it was a Greek trading post established by Phocaeans c. 340 bc. It  became a Roman town and eventually a fief of the Grimaldi family (see  Monaco) from 1384 to 1608. It is noted as a winter resort and for its  Roman ruins.</p><p>antibiotic Chemical substance that in dilute solutions can inhibit the  growth of microorganisms or destroy them with little or no harm to the  infected host. Early antibiotics were natural microbial products, but chem�  ists have modified the structures of many to produce semisynthetic and  even wholly synthetic ones. Since the discovery of penicillin (1928), anti�  biotics have revolutionized the treatment of bacterial, fungal, and some  other diseases. They are produced by many actinomycetes (e.g., streptomy�  cin, tetracycline) and other bacteria (e.g., polypeptides such as bacitracin)  and by fungi (e.g., penicillin). Antibiotics may be broad-spectrum (active  against a wide range of pathogens) or specific (active against one, or one  class). Drawbacks include activity against beneficial microorganisms,  often causing diarrhea; allergies; and development of drug-resistant strains  of the targeted microorganisms.</p><p>antibody Molecule in the immune system that circulates in blood and  lymph in response to invasion by an antigen. Antibodies are globulins  formed in lymphoid tissues by B cells, whose receptors are specialized to  bind to a specific antigen. These receptors are copied as antibodies that  attack the target antigens by binding to them, either neutralizing them or  triggering a complement reaction. Antibodies have widely varying binding  sites, providing protection from a wide range of infectious agents and  toxic substances. Antibodies derived from the blood serum of infected  people or animals are often given in an antiserum for quick immuniza�  tion against fast-acting toxins or microbes. In 1975 Cesar Milstein and col�  leagues developed a process for producing specific antibodies in virtually  limitless amounts; these monoclonal antibodies can deliver radiation or  drugs directly to specific antigens. See also antitoxin; reticuloendothelial  SYSTEM.</p><p>Antichrist Chief enemy of Christ who would reign at the end of time,  first mentioned in the epistles of St. John. The idea of a mighty ruler who  will appear at the end of time to fight against the forces of good was  adapted from Judaism; the Jewish concept in turn had been influenced by  Iranian and Babylonian myths of the battle of God and the devil at the end  of time. In the Book of Daniel the evil one is a military leader modeled  on Antiochus IV Epiphanes, who persecuted the Jews. In several books of  the New Testament, the Antichrist is a tempter who works by signs and  wonders and seeks divine honors. It was a potent concept in medieval  Christianity that received the attention of many commentators including  Adso of Montier-en-Der, whose work became the basic medieval treatise  on the Antichrist. During the Middle Ages, popes and emperors strug�  gling for power often denounced each other as the Antichrist, and during  the Reformation, Martin Luther and other Protestant leaders identified the  papacy itself as the Antichrist.</p><p>anticoagulant Substance that prevents blood from clotting by sup�  pressing the synthesis or function of various clotting factors (see coagu�  lation). Anticoagulants are given to prevent thrombosis and used in  drawing and storing blood. There are two main types of anticoagulants:  heparin and vitamin K antagonists (e.g., warfarin). The latter have longer-</p><p>lasting effects, interfering in the liver�s metabolism of vitamin K to cause  production of defective clotting factors. Anticoagulant therapy carries a  high risk of uncontrollable hemorrhage.</p><p>Anticosti Island Island, Gulf of St. Lawrence. Lying at the mouth of  the St. Lawrence River in southeastern Quebec, it is 140 mi (225 km) long;  its greatest width is 35 mi (56 km). Visited by Jacques Cartier in 1534, it  became part of Quebec province in 1774. Port-Menier is its present-day�  and only�settlement. It is now primarily a recreation area.</p><p>antidepressant Any drug used to treat depression. The three main  types inhibit the metabolism of serotonin and norepinephrine in the brain.  The aim is to keep these monoamine neurotransmitters from dropping to  levels associated with depression. The drugs may take a few weeks to  show any effect. Tricyclic antidepressants, which inhibit inactivation of  norepinephrine and serotonin, help more than 70% of patients. Monoam�  ine oxidase (MAO) inhibitors apparently block the action of MAO, an  enzyme that helps break down norepinephrine, serotonin, and dopamine in  neurons. They have unpredictable side effects and are usually given only  when tricyclic drugs do not help. Selective serotonin reuptake inhibitors  (SSRIs) apparently block reabsorption only of serotonin, allowing its lev�  els to build up in the brain. SSRIs, which include fluoxetine (trade name  Prozac), often help with depression unrelieved by tricyclics or MAO  inhibitors and have milder side effects.</p><p>antidote Remedy to counteract the effects of a poison or toxin. Admin�  istered by mouth, intravenously, or sometimes on the skin, it may work  by directly neutralizing the poison; causing an opposite effect in the body;  binding to the poison to prevent its absorption, inactivate it, or keep it  from fitting a receptor at its site of action; or binding to a receptor to pre�  vent the poison�s binding there, blocking its action. Some poisons are not  active until converted to a different form in the body; their antidotes inter�  rupt that conversion.</p><p>Antietam \an-'te-t3m. Battle of (Sept. 17, 1862) Decisive and bloody  battle of the American Civil War that halted the Confederate advance on  Maryland. Following victory in the Second Battle of Bull Run, Gen. Rob�  ert E. Lee moved his troops into Maryland with an eye to capturing Wash�  ington, D.C. They were stopped by Union troops under George B.  McClellan at Antietam Creek, Md. Confederate casualties numbered some  13,700, and Union losses were about 12,400. McClellan was criticized  for allowing Lee�s forces to retreat to Virginia, but the victory encour�  aged Pres. Abraham Lincoln to issue a preliminary Emancipation Procla�  mation.</p><p>antifreeze Any substance that lowers the freezing point of water, pro�  tecting a system from the ill effects of ice formation. Antifreezes such as  ethylene glycol or propylene glycol commonly added to water in automo�  bile cooling systems prevent damage to radiators. Additives to prevent  freezing of water in gasoline (e.g., Drygas) usually contain methanol or  isopropanol. Organisms that must survive freezing temperatures use vari�  ous chemicals to inhibit ice crystal formation in their cells and tissues:  glycerol or dimethyl sulfoxide in insects, glycerol or trehalose in other inver�  tebrates (nematodes, rotifers), and proteins in Antarctic fishes.</p><p>antigen Van-ti-jsnN Foreign substance in the body that induces an  immune response. The antigen stimulates lymphocytes to produce antibod�  ies or to attack the antigen directly (see antibody;immunity). Virtually any  large foreign molecule can act as an antigen, including those of bacteria,  viruses, parasites, foods, venoms, blood components, and cells and tis�  sues of various species, including other humans. Sites on the antigen�s  surface fit and bind to receptor molecules on the lymphocytes� surface,  stimulating the latter to multiply and initiate an immune response that  neutralizes or destroys the antigen.</p><p>Antigone \an-'ti-g9-ne\ In Greek legend, the daughter born of the inces�  tuous relationship between Oedipus and his mother, Jocasta. After Oedi�  pus had blinded himself in self-punishment, Antigone and her sister  Ismene served as his guides, following him into exile. When he died,  Antigone returned to Thebes, where her brothers Eteocles and Polyneices  were at war. Both were killed, and Creon, the new king, declared that  because Polyneices was a traitor, his corpse should remain unburied.  Unwilling to let the body be defiled, Antigone buried him; when Creon  condemned her to death, she hanged herself. Her story was dramatized  by Sophocles and Euripides (in Euripides� version she escapes and joins her  beloved, Haemon).</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Antigonid dynasty &#x25BA; antinovel I 83</p><p>Antigonid dynasty (306-168) Ruling house of ancient Macedonia.  Antigonus I was proclaimed king in 306 bc after his son Demetrius con�  quered Cyprus, thus giving his father control of the Aegean, the eastern  Mediterranean, and most of the Middle East. Under Demetrius II (r. 239-  229 bc), Macedonia was weakened by war with the Greek Achaean and  Aetolian leagues. Antigonus III (d. 221) reestablished the Hellenic Alli�  ance, restoring Macedonia to a strong position in Greece. Under Philip V,  Macedonia first clashed with Rome, in 215. Philip�s defeat upset the old  balance of power, and Rome became the decisive force in the eastern  Mediterranean. The defeat of his successor, Perseus, at Pydna in 168 bc  marked the end of the dynasty.</p><p>Antigonus I Monophthalmus \an- , tig-3-n9s...- I man-3f- , thal-m9s\  or Antigonus I Cyclops Latin "One-Eyed" (b. 382�d. 301 bc,</p><p>Phrygia, Asia Minor) Founder of the Macedonian dynasty of the Anti-  gonids. He served as a general under Alexander the Great. From the plots,  alliances, and wars among Alexander�s successors, he emerged in control  of Asia Minor and Syria, though he soon relinquished the lands east of  the Euphrates to Seleucus I Nicator. In 307 his son Demetrius I ousted the  governor of Athens and conquered Cyprus, giving Antigonus control of  the eastern Mediterranean, the Aegean, and Asia Minor. In 306 he was  proclaimed king of the empire by the assembled army. In 302 he and his  son renewed the Panhellenic League (consisting of all the Hellenic states  except Sparta, Messenia, and Thessaly), in order to ensure peace in Hel�  las and protect Antigonus. His dreams of taking Macedonia itself and  Alexander�s entire former empire died with him at the Battle of Ipsus  (301), the only battle he ever lost.</p><p>Antigonus II Gonatas \'gan-ot-3s\ (b. c. 320�d. 239 bc) King of  Macedonia (276-239 bc). The son of Demetrius I Poliorcetes, he defeated  the Gauls in Greece (279) and in Asia Minor (277), occupied key cities,  and made alliances. He defeated Pyrrhus of Epirus in Greece (272) to  solidify his control in Macedonia. In the Chremonidean War (267-261),  he achieved lasting victory over Egypt, Sparta, and Athens. He allied with  the Aetolian League and local tyrants to stave off incursions of the Achaean  League. His defeat of the Egyptian fleet at Andros (244?) assured Mace�  donian hegemony in the Aegean.</p><p>Antigua and Barbuda \an- , t9-g3...bar- , byu-do\ Island country,  Lesser Antilles, Caribbean Sea. It consists of three islands: Antigua, Bar�  buda, and Redonda. Area: 171 sq mi (442 sq km). Population (2005 est.):  77,800. Capital: St. John's (on Antigua). The majority of the population  are descendants of African slaves brought in during colonial times. Lan�  guage: English (official). Religion: Christianity (mostly Protestant; also  Roman Catholic). Currency: Eastern Caribbean dollar. The largest of the  islands is Antigua (108 sq mi [280 sq km]), which lacks forests, moun�  tains, and rivers and is subject to droughts. The main anchorage is the  deepwater harbour of St. John�s. Barbuda�25 mi (40 km) north of Anti�  gua, 62 sq mi (161 sq km) in area, and mostly uninhabited�is home to  a large bird sanctuary; its only human settlement is Codrington, on the  western coast. Redonda, an uninhabited rock (0.5 sq mi [1.3 sq km]), lies  southwest of Antigua. Tourism is the mainstay of the country�s economy;  offshore banking is growing. Christopher Columbus visited Antigua in 1493  and named it after a church in Sevilla, Spain. It was colonized by English  settlers in 1632, who imported African slaves to grow tobacco and sug�  arcane. Barbuda was colonized by the English in 1678. In 1834 the  islands� slaves were emancipated. Antigua (with Barbuda) was part of the  British colony of the Leeward Islands from 1871 until that colony was  defederated in 1956. The islands achieved full independence in 1981. See  map opposite.</p><p>antihistamine V.an-ti-'his-to-.men, .an-ti-'his-to-monV Synthetic drug  that counteracts the effects of released histamine in the body. Antihista�  mines compete with histamine at one of the three types of histamine  receptors, preventing allergic attacks (see allergy) or inflammation. Some  antihistamines also prevent motion sickness and vertigo. Drowsiness is a  frequent side effect. H 2 antihistamines, which bind to the second recep�  tor type, are used to control gastric-acid secretion (see stomach) and treat  PEPTIC ULCERS.</p><p>Antilles \an-'til-ez. Greater and Lesser Two groups of islands in  the West Indies, bounding the Caribbean Sea on the north and east, respec�  tively. The Greater Antilles include the largest islands (Cuba, Jamaica,  Hispaniola, and Puerto Rico), the Lesser Antilles all being much smaller.  The name Antilia originally referred to semimythical lands located some�  where west of Europe across the Atlantic. After Christopher Columbus�s</p><p>discoveries, the Spanish name Antillas was commonly assigned to the new  lands; �Sea of the Antilles� in various European languages is used as an  alternative name for the Caribbean Sea.</p><p>antimatter Substance composed of elementary particles having the  mass and electric charge of ordinary matter (such as electrons and protons)  but for which the charge and related magnetic properties are opposite in  sign. The existence of antimatter was posited by the electron theory of  P.A.M. Dirac. In 1932 the positron (antielectron) was detected in cosmic  rays, followed by the antiproton and the antineutron detected through the  use of particle accelerators. Positrons, antiprotons, and antineutrons, col�  lectively called antiparticles, are the antiparticles of electrons, protons,  and neutrons, respectively. When matter and antimatter are in close prox�  imity, annihilation occurs within a fraction of a second, releasing large  amounts of energy.</p><p>antimetabolite N.an-ti-mo-'ta-bo-.lhA Substance that competes with,  replaces, or inhibits a specific compound within a CELL, whose function�  ing is thereby disrupted. Because its structure resembles the compound�s,  it is taken up by the cell, but it does not react in the same way with the  enzyme that acts on the usual compound. It may inhibit the enzyme or be  converted into an aberrant chemical. Many antimetabolites are useful in  treating disease, including sulfa drugs, which disrupt bacterial but not  human metabolism for bacterial diseases, and others (e.g., methotrexate,  5-fluorouracil) for various cancers.</p><p>antimony Van-to-.mo-neX Semimetallic to metallic chemical element  (see metal), chemical symbol Sb, atomic number 51.

Anti�  friction alloys with tin and lead (babbitt metals) are used as components  of machine bearings. Antimony compounds (valences 3, 4, and 5) are  widely used as flame retardants in paints, plastics, rubber, and textiles;  others are used as paint pigments.</p><p>anti novel Type of avant-garde novel that departs from traditional nov-  elistic conventions by ignoring such elements as plot, dialogue, and  human interest.

Founded in 300 bc by the Seleucid dynasty,  Antioch was the centre of the Seleucid power until 64 bc, when it became  the capital of the province of Syria under the Roman Republic and Empire.  An early centre of Christianity, the city was the headquarters of St. Paul  c. ad 47-55. Despite being briefly occupied by the Persians in the 6th  century, it remained part of the Byzantine Empire until the Arab invasion  of the 7th century. Thereafter it returned to Byzantine rule (969) and was  seized by the Turkish Seljuq dynasty (1084) before being captured by the  Crusaders in 1098. (See Crusades.) From 1268 it was ruled by the Mam-  lOk dynasty, and it was absorbed by the Ottoman Empire in 1517. The city  remained under their control until World War I (1914-18), when it was  transferred to Syria. It was made part of the Republic of Turkey in 1939.  The economy of the modem town is based on agriculture and light manu�  facturing.</p><p>Antiochus I Soter \an-'tI-3-k3s... , so-ter\ (b. c. 324�d. 261 bc) King  of Seleucid Syria in the east (2927-281 bc) and later overall (281-261).  Son of Seleucus I, he consolidated the Seleucid kingdom, founded numer�  ous cities, and expanded trade routes. In 281 he contended with revolts  in Syria and northern Anatolia and fought a war with Antigonus II Gona-  tas. With the defeat of the Gauls in Greece (279), he and Antigonus signed  a pact of nonintervention. The Gauls in Asia Minor were not defeated  until 275, after which he was hailed as Soter (�Saviour�) by appreciative  Ionians. He settled Greeks in Asia Minor and Persia to counter invasions,  and he worked to revive Babylonian culture. Though he won Phoenicia  and the coast of Asia Minor from Egypt, he soon lost them, and in 261  he lost much of northern Asia Minor to Pergamum.</p><p>Antiochus III known as Antiochus the Great (b. 242�d. 187 bc,</p><p>near Susa, Iran) Seleucid king of the  Syrian empire (223-187 bc). After  quelling a rebellion by Achaeus, his  governor in Asia Minor (213), Anti�  ochus marched east to India (212�</p><p>205). He forged a peaceful alliance  with Armenia and forcible ones with  Parthia and Bactria, stilling resis�  tance to his campaign. After the  death of Ptolemy IV, Antiochus and  Philip V of Macedonia divided most  of his empire, Antiochus taking the  southern and eastern lands, including  Palestine (c. 202). He then marched  against Egypt, concluding a peace in  195, through which he acquired  southern Syria and Ptolemy�s terri�  tories in Asia Minor. Rome grew  angry with Antiochus after he admitted Hannibal of Carthage to his court;  when Antiochus took a force to defend the Aetolians against Rome, Rome  struck against him, eventually defeating him at Magnesia (189). He gave  up lands in Europe and western Asia Minor but kept Syria, Mesopotamia,  and western Iran. He was murdered while exacting much-needed tribute  near Susa.</p><p>Antiochus IV Epiphanes \i-'pif-3-,nez\ (b. c. 215�d. 164 bc, Tabae,  Iran) Seleucid king of the Hellenistic Syrian kingdom (175-164 bc). Son  of Antiochus III, he was taken hostage in Rome (189-175), where he  learned about Roman institutions. On his release, he ousted a usurper to  take over Syria. He conquered Egypt except Alexandria (169) and ruled  Egypt as regent for his nephew Ptolemy VI. The Roman defeat of his  Macedonian allies neutralized his victories in Cyprus and Egypt (168),  and he was forced to leave both, though he kept southern Syria. He took  Jerusalem (167) and enforced its Hellenization; Jewish rites were forbid�  den on pain of death. In 164 Judas Maccabaeus and the anti-Greek Jews  conquered Judaea except for the Acra in Jerusalem (164), tore down the  altar of Zeus, and reconsecrated the Temple. Antiochus then turned to  defending his empire against the Parthians in the east, regained Armenia,  and went on to the Arabian coast before dying in Persis.</p><p>antioxidant' Any of various compounds added to certain foods, natural  and synthetic rubbers, gasolines, and other products to retard autoxidation</p><p>(combination with oxygen in the air at room temperature) and its effects.

He was assassinated by a rival four years later,  but his son, Herod the Great, was made king of Judaea.</p><p>Antiphon \'an-ti-,fan\ (fl. c. 480-411 bc) Orator and statesman. The first  Athenian known to practice rhetoric professionally, he wrote speeches for  others to give in court but was reluctant to appear in public debate. He  may have instigated the revolution of the oligarchic Council of the Four  Hundred, an attempt to seize the Athenian government in the midst of war.  When the oligarchy fell, he defended his role in the overthrow in a speech  called by Thucydides the greatest defense ever made, but he was nonethe�  less executed for treason.</p><p>anti pope In Roman Catholicism, a person who tries to take the place of  the legitimately elected pope. Some antipopes were elected by factions in  doctrinal disagreements, and others were chosen in double elections arbi�  trated by secular authorities or picked as third candidates in an effort to  resolve such disputes. The earliest of the antipopes appeared in the 3rd  century. During the Investiture Controversy, Henry IV appointed an anti�  pope, and several more antipopes claimed the papal office over the next  200 years as a result of disputed elections or further struggles with secu�  lar rulers. The principal age of the antipope came after the papal court  was moved from Rome to Avignon in the 14th century (see Avignon  papacy), an event that led to the Western Schism of 1378-1417. During this  era, the popes now considered canonical were elected in Rome, and the  antipopes were elected in Avignon.</p><p>Antirent War (1839-46) Civil protest by leaseholding farmers in upper  New York state. Protesting outdated laws based on semifeudal leasehold�  ing practices of the early Dutch estate owners, the leaseholders of Albany  county in 1839 refused to pay back rent. The governor called out the mili�  tia to quell the violence. Sporadic acts of resistance against rent and tax  collection spread across the state, and in 1845 the governor declared mar�  tial law. In 1846 a new state constitution abolished the leasehold system.</p><p>antiseptic Any of a variety of agents applied to living tissue to destroy  or inhibit growth of infectious microorganisms. An antiseptic�s efficiency  depends on concentration, time, and temperature. It is most valuable in  the disinfection of contaminated wounds or skin surfaces when a wide  margin exists between the concentration at which it is germicidal and that  at which it is toxic to the body�s cells. Many antiseptics destroy specific  types or forms of microorganisms (e.g., bacteria but not spores). Among  the major families of antiseptics are alcohols, phenols, chlorine and iodine  compounds, MERCURY-based tinctures, certain acridine dyes, and some essen�  tial oils. Antiseptics are distinguished from disinfectants, which are ger�  micidal agents used to destroy microorganisms on inanimate surfaces. See  also ANTIBIOTIC.</p><p>antitank weapon Any of several guns, missiles, and mines intended  for use against tanks. Land mines, ordinary artillery, and other projectiles  were used to destroy tanks in World War I. By World War II antitank guns  had been developed; they frequently fired special ammunition such as the  hollow charge shell, which exploded on impact with great penetrating  force. Various antitank missiles and launching devices, including the  bazooka, were also used in the war.</p><p>antitoxin Antibody formed in the body in reaction to a bacterial toxin,  which it can neutralize. People who have recovered from bacterial dis�  eases often develop specific antitoxins that give them immunity against  recurrence. Injecting an animal (usually a horse) with increasing doses of  toxin produces a high concentration of antitoxin in the blood. The result�  ing highly concentrated preparation of antitoxins is called an antiserum.  The first antitoxin developed (1890) was specific to diphtheria; today, anti�  toxins are also used to treat botulism, dysentery, gas gangrene, and tetanus.</p><p>antitrust law Any law restricting business practices that are consid�  ered unfair or monopolistic. Among U.S. laws, the best known is the  Sherman Antitrust Act of 1890, which declared illegal �every contract,</p><p>Antiochus III, coin, late 3rd-early 2nd  century bc; in the British Museum.</p><p>COURTESY OF THE TRUSTEES OF THE BRITISH MUSEUM;  PHOTOGRAPH, J.R.

The ant-  lion larva digs a funnel-shaped  sandy pit by using its oval, bristled  abdomen, then buries itself in the pit  with only its powerful jaws uncov�  ered. Any small insect that ventures  over the pit�s edge slips to the bot�  tom and is seized by the antiion,  which sucks the contents of its vic�  tim and throws out the empty skin.</p><p>The adult antiion does not feed. The  best known of the 65 described spe�  cies occurs in North America and Europe.</p><p>Antofagasta \,an-t6-fa-'gas-ta\ Seaport (pop., 1999: est.: 243,038),  capital of Antofagasta region, northern Chile. Located on Moreno Bay, it  was a Bolivian city until it was taken by Chile in 1879 (see War of the  Pacific). Its early growth resulted from the nitrate boom that began in 1866  and from the Caracoles silver discovery in 1870. The largest city of north�  ern Chile, it remains a supply source for the mines and is a communica�  tions centre on the Pan-American Highway.</p><p>Antonello da Messina X.an-to-'nel-o-da-ma-'se-noV (b. c. 1430, Mes�  sina, Sicily�d. c. Feb. 19, 1479,</p><p>Messina) Italian painter. Trained in  Naples, then a cosmopolitan art cen�  tre, he studied the Flemish artists,  notably Jan van Eyck. Based on these  experiences, when he returned to  Venice he introduced oil painting  and Flemish pictorial techniques into  mid-15th-century Venetian art. His  major works were altarpieces and  portraits. In Venice he executed the  San Cassiano altarpiece, of which  three fragments remain. His portrait  busts in three-quarter view, combin�  ing Flemish detail with Italian gran�  deur, became fashionable.</p><p>Antonello�s practice of building  form with colour rather than line and  shade greatly influenced the subse�  quent development of Venetian  painting. See also Venetian school.</p><p>Antonescu V.an-to-'nes-kiA, Ion  (b. June 15, 1882, Pitesti, Rom.�d.</p><p>June 1, 1946, near Jilava) Romanian  marshal. He served in World War I and later became chief of staff (1934)  and minister of defense (1937). Appointed prime minister in 1940, he  established a fascist dictatorship and openly supported the Axis Powers.  Initially he won broad support for his domestic reforms and declaration  of war against the Soviet Union (1941), but that support eroded. His  regime was overthrown in 1944, and he was later executed as a war  criminal.</p><p>Antonine Wall Roman frontier barrier in Britain. It ran 37 mi (59 km)  across Scotland between the River Clyde and the Firth of Forth. Ordered  by Antoninus Pius and built in ad 142 by the governor of Britain, it was  about 15 ft (5 m) wide and 10 ft (3 m) high; a ditch 40 ft (12 m) wide  and 12 ft (4 m) deep ran in front of it and a road behind. It was controlled  by 19 forts spaced at intervals of 2 mi (3 km). Its construction moved the  northern boundary of Roman Britain into Scotland, providing defense  against the northern tribes beyond Hadrian's Wall, which lay to the south.  The wall was abandoned by 196, but traces remain.</p><p>Antoninus Pius X.an-to-'nI-nos-'pI-osX in full Caesar Titus Aelius  Hadrianus Antoninus Augustus Pius (b. Sept. 19, 86, Lanuvium,  Latium� d. March 7, 161, Lorium, Etruria) Roman emperor (ad 138�</p><p>161). Of Gallic origins, he served as  consul (120) before being assigned  judicial administrative duties in Italy.</p><p>He later governed the province of  Asia (c. 134). He became an adviser  to Hadrian and in 138 was made  Hadrian�s heir. On accession he had  the deceased emperor declared a  god; for such dutiful acts he was  named Pius (�Pious�). He quelled  rebellions in Britain and other prov�  inces and built the Antonine Wall.</p><p>Antonioni X.an-.to-ne-'o-neV  Michelangelo (b. Sept. 29, 1912,</p><p>Ferrara, Italy) Italian film director  and producer. He wrote film reviews  and studied filmmaking before  directing his short film The People of  the Po Valley (1947). His first majoi Antoninus Pius, marble bust; in the Brit-  film, The Girl Friends (1955), was j s h Museum,  followed by the international sue- reproduced by courtesy of the trustees of the</p><p>cesses L�avventura (1960), Eclipse BRmSHMUSEUM _</p><p>(1962), and Blow-up (1966). His</p><p>other films include The Red Desert (1964), Zabriskie Point (1970), and  The Passenger (1974). In Antonioni�s films, plot and dialogue are sub�  ordinated to the visual image, which becomes a metaphor of human exist�  ence rather than a record of it.</p><p>Antony, Mark Latin Marcus Antonius (b. c. 83�d. August, 30  bc) Roman general. After military  service (57-54), he joined the staff of  his relative Julius Caesar. He helped  Caesar drive Pompey from Italy in 49  and in 44 was made co-consul. After  Caesar�s assassination, Octavian  (later Caesar Augustus) initially  opposed Antony but later formed the  Second Triumvirate with Antony and  Lepidus. Antony helped defeat  republican forces at Philippi and took  control of Rome�s eastern provinces.</p><p>On a mission to Egypt to question  Cleopatra about her loyalty, he  became her lover (41-40). He  returned to Italy in 40 to settle dif�  ferences with Octavian, whereupon  he received command of the eastern  provinces. To strengthen his posi�  tion, he agreed to marry Octavian�s  sister Octavia. When relations with  Octavian again collapsed, he headed  for Syria and sent for Cleopatra for aid. Octavian sent Octavia to him,  and, when Antony ordered her back to Rome, a fatal breach opened. The  Triumvirate ended in 32, leaving Antony little support in Rome. He  divorced Octavia, and Octavian declared war on Cleopatra. Antony lost  the Battle of Actium, and he and Cleopatra fled to Egypt, pursued by Octa�  vian. When resistance became futile, they committed suicide.</p><p>Antrim Town and district (pop., 2001: 48,366), Northern Ireland. It is  also the name of a former Northern Irish county. The town borders Lough  Neagh. In 1798 it was the scene of a battle in which several thousand  nationalist insurgents led by Henry J. McCracken were defeated by the  British. A busy market centre, Antrim town was formerly an important  locale for the linen industry. The area has evidence of human inhabita�  tion dating to c. 6000 bc. Anglo-Norman adventurers arrived in the 12th  century ad, and the area became part of the earldom of Ulster. The inva�  sion by Edward Bruce from Scotland in 1315 caused the decline of Brit�  ish power. In the 1973 administrative reorganization of Northern Ireland,  the county was divided into several districts.</p><p>Antwerp French Anvers \a n -'ver\ Flemish Antwerpen  \'ant-,ver-p9n\ City (pop., 2000 est.: 446,500), capital of Antwerp prov�  ince, Belgium.

Following destructive invasions it went into decline but began to  revive after Napoleon�s improvement of the harbour c. 1803. It was part  of the Kingdom of the Netherlands (1815-30), then was ceded to Belgian  nationalists. Its current economic life centres around shipping, port-related  activities, and major manufacturing.</p><p>antyesti \ant-'yes-te\ Hindu funeral rites. They generally involve cre�  mation followed by disposal of the ashes in a sacred river. As soon as  possible after death, the body is removed to the cremation grounds, usu�  ally on the riverbank. The eldest son of the deceased and a priest perform  the final rites. For 10 days, the mourners are considered impure as they  perform rites intended to provide the soul of the deceased with a new  spiritual body for the next life. At a prescribed date, the bones are col�  lected and buried or immersed in a river.</p><p>Anu Va-.niA Mesopotamian sky god. He belonged to a triad that included  Bel and Ea. Though he was the highest god, his role in mythology, hymns,  and cult was small. The father of all gods, evil spirits, and demons, and  the god of kings and the calendar, he was depicted with headdress and  horns signifying strength. His Sumerian counterpart, An, was originally  envisaged as a great bull; he probably began as a god of herders.</p><p>Anu Va-.nuV, Chao (b. 1767�d. 1835, Bangkok, Siam) Ruler of the  central Lao kingdom of Vientiane (r. 1804-29). In his youth Anu fought  with the Siamese against the Burmans (Burmese) and won Siamese  respect for his military prowess. Chosen by them to be king of Vientiane,  he undertook major public works and cultivated good relations with Viet�  nam. He had the Siamese appoint his son ruler of the southern Lao prin�  cipality of Champassak and began to plot a rebellion for Lao  independence. His armies nearly reached Bangkok, but the revolt was  quelled and Vientiane was sacked and later razed. Anu fled to the forests  but was captured, punished, and killed.</p><p>Anubis Xo-'nii-bosX Ancient Egyptian god of the dead, represented as a  jackal or as a man with the head of a jackal. In the Early Dynastic period  and the Old Kingdom he was preeminent as lord of the dead, but he was  later overshadowed by Osiris. Anubis was associated with the care of the  dead and was credited with the invention of embalming, an art he first  practiced on the corpse of Osiris. Later assigned the role of conducting  souls into the underworld, he was sometimes identified in the Greco-  Roman world with Hermes.</p><p>Anuradhapura Xo-'nur-o-do-.pur-oV (c. 3rd century Bc-10th century  ad) Sinhalese kingdom centred at Anuradhapura in Sri Lanka. Though  plagued by invasions from southern India (which took actual control of  the kingdom several times) and internal strife among warring clans, the  kingdom of Anuradhapura developed a high degree of culture. Its com�  plex irrigation system is often considered its major achievement. The  modern city of Anuradhapura (pop. 2001 prelim.: 56,632) contains vast  Buddhist ruins and a bo tree grown from a slip of the tree under which  the historical Buddha is said to have reached Enlightenment.</p><p>Anvers See Antwerp</p><p>anvil Iron block on which metal is placed for shaping, originally by hand  with a hammer. The blacksmith�s anvil is usually of wrought iron (some�  times of cast iron), with a smooth working surface of hardened steel. A  projecting conical beak, or horn, at one end is used for hammering curved  pieces of metal. When power hammers are used, the anvil is supported  on a heavy block, which in turn rests on a strong foundation of timber  and masonry or concrete. See also smithing.</p><p>anxiety In psychology, a feeling of dread, fear, or apprehension, often  with no clear justification. Anxiety differs from true fear in that it is typi�  cally the product of subjective, internal emotional states rather than a  response to a clear and actual danger. It is marked by physiological signs  such as sweating, tension, and increased pulse, by doubt concerning the  reality and nature of the perceived threat, and by self-doubt about one�s  capacity to cope with it. Some anxiety inevitably arises in the course of  daily life and is normal; but persistent, intense, chronic, or recurring anxi�  ety not justified by real-life stresses is usually regarded as a sign of an  emotional disorder.

It was founded, according to legend, by Ante-</p><p>ias, son of Odysseus and Circe. It was a stronghold of the Volsci in the 5th  century bc. Conquered by Rome in 338 bc, Antium (as it was then known)  became a resort for wealthy Romans. Nero and Caligula were born there.  Destroyed by the Saracens in the 9th-10th centuries, it remained virtu�  ally deserted until 1698, when Pope Innocent XII built a new port nearby.  In 1944 it was the scene of a bloody but successful amphibious landing  by Allied forces during World War II.</p><p>ANZUS Pact officially Pacific Security Treaty Security pact for  the South Pacific, signed in 1951 by Australia, New Zealand, and the U.S.  (hence its acronym). The U.S. first suggested a pact to Australia in the  wake of the U.S.-Japan Security Treaty and fears of Japanese rearmament.  The signatories agreed to maintain a consultative relationship for their  collective security. In the 1980s New Zealand refused to let ships carry�  ing nuclear weapons dock at its ports; the U.S., refusing to identify its  nuclear-armed ships, suspended its treaty obligations to New Zealand in  1986, and the treaty has since been nonoperative with reference to New  Zealand.</p><p>aorta Artery that carries blood from the heart to all the organs and struc�  tures of the body. Where the left ventricle opens into the aorta, a valve  prevents backflow of blood into the heart. The aorta ascends from the  heart, arches over it to the left, then descends into the trunk. Arteries  branch off along its length until it divides at hip level into arteries that  go to the legs.</p><p>aorta, coarctation of the Congenital disorder involving narrowing  of a short section of the aorta�s arch over the heart. It causes a charac�  teristic murmur, abnormally high blood pressure in the arms, and reduced  blood flow to the abdomen, pelvis, and legs. It increases the workload of  the left ventricle, which usually becomes enlarged. Surgical reconstruc�  tion or replacement (depending on the person�s age) of the narrowed area  is most effective in the young.</p><p>Aosta \a-'os-ta\ City (pop., 2001: 33,926), capital of Valle d' Aosta  region, northwestern Italy.

The Eastern  Apache were predominantly hunting and gathering societies, while their  Western counterparts relied more on farming. Their ancestors had come  down from the north, as is evident from their languages; Apachean lan�  guages are distantly related to other Athabascan languages spoken in  Canada. They settled the Plains, but with the introduction of the horse  they were pressed south and west by the Comanche and Ute. They  attempted to befriend the Spanish, the Mexicans, and later the U.S. In  1861, however, there began a quarter-century confrontation between U.S.  military forces and the Apache and Navajo. The Apache wars were among  the fiercest fought on the frontier. The last ended in 1886 with the sur�  render of Geronimo. The Chiricahua Apache were evacuated from the  West and held successively in Florida, Alabama, and Oklahoma. In the  2000 U.S. census some 57,000 people claimed sole Apache descent.

The city was built by Antiochus I (Antiochus  Soter) in the 3rd century bc on the Maeander (Menderes) River. Super�  seding the fortress city of Celaenae, it was placed in a commanding posi�  tion on the great east-west trade route of the Seleucid dynasty. In the 2nd  century bc Apamea passed to the rule of the Roman Republic and Empire and  became an important centre for Italian and Jewish traders. Declining after  the 3rd century ad, it was captured by Turkish invaders in 1070 and there�  after was destroyed by an earthquake.</p><p>apartheid \o-'par-,tat\ (Afrikaans: �apartness� or �separateness�)  Policy of racial segregation and political and economic discrimination  against non-European groups in South Africa. The term was first used as  the name of the official policy of the National Party in 1948, though racial  segregation, sanctioned by law, was already widely practiced. The Group  Areas Act of 1950 established residential and business sectors in urban  areas for each �race� and strengthened the existing �pass� laws, which  required non whites to carry identification papers. Other laws forbade most  social contacts between those of European descent and others, authorized  segregated public facilities, established separate educational standards,  restricted each group to certain types of jobs, curtailed nonwhite labour  unions, denied nonwhite participation in the national government, and  established various black African �homelands,� partly self-governing  units that were nevertheless politically and economically dependent on  South Africa. These so-called homelands were not recognized by inter�  national governments. Apartheid was always subject to internal criticism  and led to many violent protests, strikes, and acts of sabotage; it also  received international censure. In 1990-91 most apartheid legislation was  repealed, but segregation continued on a de facto basis. In 1993 a new  constitution enfranchised blacks and other racial groups, and all-race  national elections in 1994 produced a coalition government with a black  majority. These developments marked the end of legislated apartheid,  though not of its entrenched social and economic effects.

Much of it has a chemical composition approximat�  ing Ca 5 (P0 4 ) 3 (F,Cl,OH). If not for its softness, apatite would be a popu�  lar gemstone; some of the material found is clear, but it is fragile and  difficult to cut and polish.</p><p>Apatosaurus Vo-.pa-to-'sor-osX Genus of giant herbivorous dinosaur,  one of the largest land animals of all time. Apatosaurus lived between  147 million and 137 million years ago during the Late Jurassic and Early  Cretaceous Periods in North America and Europe. It weighed as much as  30 tons and was as long as 70 ft (21 m), including the very long neck and  tail. Formerly known as Brontosaurus because of incomplete fossil evi�  dence, its head was depicted until 1978 as massive and snub-nosed, with  spoonlike teeth; scientists now know the animal had a slender, elongated  skull and long, peglike teeth. Skeletal evidence indicates that, despite their  great bulk, apatosaurs were primarily land animals.</p><p>ape Any of the tailless primates known as the lesser apes (gibbons and  siamangs; family Hylobatidae) or the great apes (chimpanzees, bonobos,  orangutans, and gorillas; family Hominidae). Apes are found in the tropi�  cal forests of western and central Africa and South Asia. They are distin�  guished from monkeys by having no tail, having an appendix, and having  a more complex brain. Apes typically move about by swinging or knuckle-  walking, though they are capable of standing erect and occasionally walk</p><p>on two feet. Highly intelligent animals, apes are very closely related to  humans, who are also categorized by zoologists as members of Homi�  nidae. As a result of habitat destruction and hunting, all the apes are now  regarded as endangered.</p><p>APEC in full Asia-Pacific Economic Cooperation Trade group  established in 1989 in response to the growing interdependence of Asia-  Pacific economies and the advent of regional economic blocs (such as the  European Union and the North American Free Trade Area) in other parts  of the world. APEC works to raise living standards and education levels  through sustainable economic growth and to foster a sense of community  and an appreciation of shared interests among Asia-Pacific countries. At  the end of the 1990s APEC�s membership included its 12 founding  members�Australia, Brunei, Canada, Indonesia, Japan, South Korea,  Malaysia, New Zealand, the Philippines, Singapore, Thailand, and the  United States�as well as Chile, China, Hong Kong, Mexico, Papua New  Guinea, Peru, Russia, Taiwan, and Vietnam. The Pacific Economic Coop�  eration Council, the South Pacific Forum, and the secretariat of the Asso�  ciation of Southeast Asian Nations maintain observer status.

They may be psychophysiological  (arousing the senses of sight, touch, smell, or hearing) or internal (e.g.,  foods, alcoholic drinks, drugs, love potions, medicinal preparations). Most  foods traditionally believed to be aphrodisiacs have no chemical compo�  nents that would have such an effect. In some cases, their reputation may  be based on a supposed resemblance to genitalia (e.g., ginseng root, rhi�  noceros horn). Drugs such as alcohol or marijuana may lead to sexual  excitation by lessening the user�s inhibitions. Few medical studies have  been conducted; the only substances medically recognized as aphrodisi�  acs are extremely hazardous to the health.</p><p>Aphrodite \,a-fr3-'dl-te\ Greek goddess of sexual love and beauty. She  is also associated with the sea and, according to legend, was born of sea  foam arising from the genitals of Uranus. Sparta, Thebes, and Cyprus  honored her as a goddess of war. Many scholars believe that her cult is  Semitic rather than Greek in origin. According to Homer, she was the  daughter of Zeus and his consort Dione, and she married Hephaestus but  betrayed him with Ares. She had many mortal lovers. Her main centres  of worship were on the islands of Cyprus and Cythera and at Corinth. As  a fertility goddess, she is associated with Eros, the Graces, and the Horae  (seasons). Venus is her Roman counterpart.</p><p>Apia \a-'pe-a\ Seaport town (pop., 2001: 38,836) and capital, Samoa. It  lies on the northern coast of Upolu Island. Its economy centres on the  export of goods to American Samoa. Robert Louis Stevenson is buried at  nearby Mount Vaea; Vailima, his former home, is now the residence of  the head of state.</p><p>apiculture See beekeeping</p><p>Apis \'a-p3s\ In ancient Egyptian religion, a sacred bull deity worshiped  at Memphis. The cult originated at  least as early as the 1st dynasty (c.</p><p>2925-c. 2775 bc). Apis was probably  at first a fertility god but became  associated with Ptah and also with  Osiris and Sokaris, gods of the dead.</p><p>When an Apis bull died, it was bur�  ied with great pomp, and the calf that  was to be its successor was installed  at Memphis. Apis�s priests drew  omens from the bull�s behaviour, and  his oracle had a wide reputation. The  worship of Serapis (a combination of  Osiris and Apis) probably arose at  Memphis in the 3rd century bc and  became one of the most widespread  Oriental cults in the Roman Empire.</p></section><section><p>aplastic \a-'plas-tik\ anemia or  anemia of bone-marrow  failure Inadequate blood-cell for�  mation by bone marrow. Pancytope�  nia is the lack of all blood-cell types  (ERYTHROCYTES, LEUKOCYTES, and PLATE�  LETS), but any combination may be  missing. Drug, chemical, or radiation exposure most often causes the dis�  ease, but about half of all cases have no known cause. It may occur at  any age. Acute disease may be quickly severe, even fatal; chronic disease  has symptoms including weakness, shortness of breath, headache, fever,  and pounding heart. There is usually a waxy pallor. Hemorrhages occur  in mucous membranes, skin, and other organs. Lack of white blood cells  lowers resistance to infection and becomes the major cause of death. Very  low platelet count may lead to severe bleeding. The treatment of choice  is bone-marrow transplantation. Otherwise treatment involves avoiding  any known toxic agent and giving fluids, glucose, and proteins (often  intravenously) as well as blood components and antibiotics.</p><p>aplite or haplite Any igneous rock of simple composition, such as  granite composed only of alkali feldspar, muscovite mica, and quartz; in</p><p>a more restricted sense, uniformly fine-grained (less than 0.08 in., or 2  mm), light-coloured igneous rocks that have a characteristic granular tex�  ture. Unlike pegmatite, which is similar but much coarser-grained, aplite  occurs in small bodies that rarely contain zones of different minerals. The  two rocks may occur together and are assumed to have formed at the same  time from similar magmas.</p><p>Apo \'a-po\, Mt. Active volcano, Mindanao, Philippines. Located west  of Davao City, it is the highest point in the Philippines, at 9,690 ft (2,954  m). In 1939 its slopes and immediate vicinity were incorporated into  Mount Apo National Park, which includes numerous peaks and valleys  as well as Malasita Falls and Sibulao Lake.</p><p>apocalypse Vs-'pa-ko-.lipsV In many Western religious traditions, the  period of catastrophic upheaval expected to occur just before the end of  the world, when God will come to sit in judgment on humankind. The  belief that the world will come to a violent and cataclysmic end exists in  Judaism and Christianity as well as in Zoroastrianism. Several of the pro�  phetic works of the Hebrew Scriptures, notably the book of Daniel, include  visions of the apocalypse. The book of Revelation (or Apocalypse) gives  a dark and dramatic picture of the end of time, when the wicked will be  punished and the good will triumph through God�s intervention. The  approach of the Last Days is expected to be marked by famines, wars,  earthquakes, plagues, and other natural disasters, along with signs in the  heavens. Today apocalyptic themes are emphasized by various religious  groups (e.g., fundamentalist Christians) and have also been taken up by  science-fiction writers. See also eschatology; millennialism.</p><p>Apocrypha \3-'pa-kr3-fo\ In biblical literature, works outside an  accepted canon of scripture. In modern usage the Apocrypha refers to  ancient Jewish books that are not part of the Hebrew Bible but are con�  sidered canonical in Roman Catholicism and Eastern Orthodoxy. Among  the various books included are Tobit, Judith, Baruch, and the Maccabees  as well as Ecclesiasticus and the Wisdom of Solomon. Protestant churches  follow Jewish tradition in judging these works apocryphal or noncanon-  ical. The term deuterocanonical is used to refer to works accepted in one  canon but not all. Pseudepigrapha are spurious works for which biblical  authorship is claimed.</p><p>Apollinaire \a-p6-le-'ner\, Guillaume orig. Guillelmus (or Wil�  helm) Apollinaris de Kos-  trowitzky (b. Aug. 26, 1880,</p><p>Rome?, Italy�d. Nov. 9, 1918,</p><p>Paris, Fr.) French poet of Polish-  Italian birth. Arriving in Paris at age  20, Apollinaire always kept his early  years obscure. In his short life he  took part in all the avant-garde  movements that flourished at the  beginning of the 20th century. His  poetry was characterized by daring,  even outrageous, technical experi�  ments. Because of his efforts to cre�  ate an effect of surprise by means of  unusual verbal associations and  word patterns, he is often considered  the herald of Surrealism. His poetic  masterpiece was Alcools (1913). His  death resulted from a head wound  received in World War I.</p><p>Apollo Most widely revered of the  Greek gods. He communicated the  will of his father Zeus, made humans aware of their guilt and purified them  of it, presided over religious and civil law, and foretold the future. His bow  symbolized distance, death, terror, and awe; his lyre symbolized music,  poetry, and dance. As a patron of the arts, he was often associated with the  Muses. He was also a god of crops and herds. He became associated with  the sun, and was even identified with Helios, the sun god. Also associated  with healing, he was the father of Asclepius. By tradition, Apollo and his  twin, Artemis, were born at Delos to Leto. Apollo�s oracle was established  at Delphi; the Pythian Games commemorated his killing (while still an  infant) of the serpent Python to take the shrine. His many lovers fared  poorly: the fleeing Daphne became a laurel tree; the unfaithful Coronis was  shot by Artemis, and Cassandra, who rejected him, was doomed to utter  true prophecies no one would believe.

The  Apollo spacecraft, supplied with their own low-powered rockets, could  brake on approach to the Moon and go into lunar orbit. They also could  release part of the spacecraft, the lunar module, with its own rocket power,  to land astronauts on the Moon and bring them back to the lunar orbiter.  In July 1969 Apollo 11 made the first lunar landing (see Edwin Aldrin;  Neil Armstrong). In 1970 Apollo 13 was damaged by an explosion in an  oxygen tank but returned safely to Earth. Later Apollo missions explored  the lunar surface extensively, collecting samples of Moon rocks and  installing instruments for research. Apollo 17, the program�s final lunar  flight, took place in 1972. In total, 12 American astronauts walked on the  Moon during six successful lunar-landing missions.</p><p>Apollo asteroid See Earth-crossing asteroid</p><p>Apollo Theatre During and after the Harlem Renaissance, a centre of  African-American popular music on 125th Street in New York City�s  Harlem district. Built in 1914, it hosted musical performers such as Bill  Robinson, Billie Holiday, Bessie Smith, Ethel Waters, Duke Ellington, and oth�  ers in the 1930s and �40s; stars such as Ella Fitzgerald, Sarah Vaughan,  and James Brown were discovered on Wednesday amateur nights. In the  1960s the Apollo featured soul artists such as the Supremes, Stevie Won�  der, and Marvin Gaye. Converted into a movie theatre in 1975, it was  reopened as a performance venue in 1983.</p><p>Apollonius Dyscolos V.ap-o-'lo-ne-os-'dis-ko-losV (fl. 2nd century ad)  Greek grammarian. Apollonius is considered the founder of the system�  atic study of grammar. Priscian based his work on the writings of Apol�  lonius. Four of Apollonius�s works survive: On Syntax and the shorter  treatises On Pronouns , On Conjunctions, and On Adverbs.</p><p>Apollonius of Perga (b. c. 240 bc, Perga, Anatolia�d. c. 190 bc,  Alexandria, Egypt) Mathematician known as �The Great Geometer.� His  Conics was one of the greatest scientific treatises of the ancient world. In  it he introduced the terms parabola, ellipse, and hyperbola. Because Con�  ics was fundamental to later advances in optics and astronomy in the  Islamic world, a 9th-century Arabic translation survived to fill in for some  of the missing Greek original. Generally, his other writings survive only  as titles.</p><p>Apollonius of Rhodes (b. c. 295 bc) Greek poet and grammarian. He  served as librarian of the famous Library of Alexandria. His Argonautica,  a romantic epic in four books about the Argonauts, is derived from Homer  and is noted for its suggestive similes, vivid descriptions of nature, and  fresh handling of old episodes.</p><p>apologetics Branch of Christian theology devoted to the intellectual  defense of faith. In Protestantism, apologetics is distinguished from polem�  ics, the defense of a particular sect. In Roman Catholicism, apologetics</p><p>refers to the defense of the whole of  Catholic teaching. Apologetics has  traditionally argued positively to  quell believers� doubts and nega�  tively against opposing beliefs to  remove obstacles to conversion. It  attempts to take objections to Chris�  tianity seriously without giving  ground to skepticism. Biblical apol�  ogetics defended Christianity as the  culmination of Judaism, with Jesus as  the Messiah. In the 2nd and 3rd cen�  turies a number of Christian writers  defended the faith against the criti�  cisms of Greco-Roman culture, and  in the 5th century St. Augustine wrote  his monumental City of God as a  response to further criticisms of  Christianity following the sack of  Rome in 410. John Calvin�s �natural  theology� attempted to establish reli�  gious truths by rational argument.  The late 18th-century argument that  a universe exhibiting design must  have a designer continues to be used;  apologists have also dealt with the challenges of Darwinism, Marxism, and  psychoanalysis. See also Apologist.</p><p>Apologist Any of the Christian writers, primarily in the 2nd century,  who attempted to provide a defense of Christianity against Greco-Roman  culture. Many of their writings were addressed to Roman emperors and  were submitted to government secretaries in order to defend Christian  beliefs and practices. The Apologists tried to prove the antiquity of Chris�  tianity as the fulfillment of Old Testament prophecy, and they argued that  the worshipers of the mythological gods were truly godless. They also  insisted on the philosophical nature of their faith and its high ethical stan�  dards. Greek Apologists include Justin Martyr and Clement of Alexandria.  Latin Apologists of the 2nd century include Tertullian. See also apologetics.</p><p>apology In literature, an autobiographical form in which a defense is  the framework for discussion of the author�s personal beliefs. Examples  include Plato�s Apology (4th century bc), in which Socrates answers his  accusers by giving a history of his life and moral commitment, and John  Henry Newman�s Apologia pro Vita Sua (1864), an examination of the  principles that inspired his conversion to Roman Catholicism.</p><p>apomixis X.a-po-'mik-sosV Reproduction by special tissues without fer�  tilization. Examples include parthenogenesis in animals (in which a new  individual develops from an unfertilized egg) and apogamy in plants (in  which the generating tissue may be either the gametophyte or the sporo-  phyte). Apomixis provides for the preservation of traits favourable to indi�  vidual survival, but it eliminates the longer-term evolutionary advantage  of genetic contribution from two parents.</p><p>apoptosis X.a-pop-'to-sosV or programmed cell death Mechanism  that allows cells to self-destruct when stimulated by the appropriate trig�  ger. It may be initiated when a cell is no longer needed, when a cell  becomes a threat to the organism�s health, or for other reasons. The aber�  rant inhibition or initiation of apoptosis contributes to many disease pro�  cesses, including cancer. Though embryologists had long been familiar  with the process of programmed cell death, not until 1972 was the mecha�  nism�s broader significance recognized. Apoptosis is distinguished from  necrosis, a form of cell death that results from injury.</p><p>Apostle Any of the 12 disciples chosen by Jesus. They were Peter, James  and John (sons of Zebedee), Andrew, Philip, Bartholomew, Matthew, Tho�  mas, James (son of Alphaeus), Thaddaeus or Judas (son of James), Simon  the Cananaean or Zealot, and Judas Iscariot. The 12 were privileged to  attend Jesus continually and receive his teaching. Peter, James, and John  formed an inner circle and were allowed to witness such events as the  Transfiguration and the agony of Jesus at Gethsemane. After the defec�  tion and death of Judas Iscariot, Matthias was elected an Apostle. Paul  also claimed the title on the ground that he had seen the Lord and been  commissioned by him.</p><p>Apostolic succession V.a-po-'sta-likN In Christianity, the doctrine that  bishops represent an uninterrupted line of descent from the Apostles of  Jesus. This succession gives bishops special powers, including the right  to confirm church members, ordain priests, consecrate bishops, and rule  over the clergy and church members of a diocese. Clement, bishop of  Rome, stated the doctrine as early as ad 95, and it is accepted by Roman  Catholic, Eastern Orthodox, Old Catholic, and several other churches.  Some Protestant churches maintain that succession is spiritual and doc�  trinal rather than ritual and historical.</p><p>apotheosis Vo-.pa-the-'o-sosX Elevation to the status of a god. The term  recognizes that some individuals cross the dividing line between human  and divine. Ancient Greek religion was disposed to belief in heroes and  demigods, and historical figures were sometimes worshiped as gods. Until  the end of the republic the Romans accepted only one apotheosis, iden�  tifying the god Quirinus with Romulus. The emperor Augustus ordered  Julius Caesar recognized as a god and thus began a tradition of deifying  emperors.</p><p>apotropaic eye V.a-po-tro-'pa-ikN Painting of a large eye or eyes used  to ward off evil. The symbol appears most commonly on Greek drinking  vessels from the 6th century bc and was perhaps thought to keep danger�  ous spirits from entering the mouth with the wine. It is also used in Turk�  ish and Egyptian art.</p><p>Appalachian Geosyncline Great downbuckle in the Earth�s crust  in the region of the present Appalachian Mountains.

The Appalachians, among the oldest mountains on Earth, extend almost  2,000 mi (3,200 km) from the Canadian province of Newfoundland and  Labrador in the northeast southwestward to Alabama in the U.S. They  include the White Mountains in New Hampshire, the Green Mountains in  Vermont, the Catskill Mountains in New York, the Allegheny Mountains  primarily in Pennsylvania, the Blue Ridge Mountains in Virginia and North  Carolina, the Great Smoky Mountains in North Carolina and Tennessee,  and the Cumberland Plateau extending from West Virginia to Alabama.  Their highest peak is Mount Mitchell in North Carolina.

Hikers and volunteers maintain the shelters and campsites. The trail�s  highest point is Clingmans Dome (6,643 ft [2,025 m]) in the Great Smoky  Mountains. With its first section opened in 1923, the trail was completed  in 1937 and became part of the National Trail System established by the  U.S. Congress in 1968.</p><p>Appalachian orogenic \,6r-3-'je-nik\ belt Mountain range that  extends more than 1,860 mi (3,000 km) along the eastern margin of North  America, from Alabama to Newfoundland.

They stand  14-16 hands (about 56-64 in. [142-  163 cm]) tall and weigh 1,000-1,100  lbs (450-500 kg). Though light, they  are also sturdy.</p><p>appanage Va-po-nij\ In France,  primarily from the 13th to the 16th  century, the giving of lands or pen�  sions to children of the royal family.</p><p>Established to provide for the younger brothers and sisters of the king,  appanages also helped develop royal administration within the lands con�  cerned. The Ordinance of Moulins (1566) made royal lands inalienable,  so all appanages would eventually revert to the crown. They were abol�  ished during the French Revolution but were briefly reestablished between  1810 and 1832.</p><p>appeal Resort to a higher court to review the decision of a lower court,  or to any court to review the order of an administrative agency. Its scope  is usually limited. In the U.S., the higher court reviews only matters in  the record of the original trial; no new evidence can be presented. The  Supreme Court of the United States hears appellate cases that it regards as  having important implications; otherwise, appeals generally stop with the  United States Courts of Appeals. See also certiorari.</p><p>appeasement Foreign policy of pacifying an aggrieved nation through  negotiation in order to prevent war. The prime example is Britain�s policy  toward Fascist Italy and Nazi Germany in the 1930s. Neville Chamberlain  sought to accommodate Italy�s invasion of Ethiopia in 1935 and took no  action when Germany absorbed Austria in 1938. When Adolf Hitler pre�  pared to annex ethnically German portions of Czechoslovakia, Chamber-  lain negotiated the notorious Munich Agreement.</p><p>Appel \'a-pel\, Karel (b. April 25, 1921, Amsterdam, Neth.) Dutch  painter, sculptor, and graphic artist. He attended Amsterdam�s Royal  Academy of Fine Arts (1940-43) and was cofounder of the COBRA group  of northern European Expressionists. In 1950 he moved to Paris; by the  1960s he had settled in New York City. An exponent of expressive abstrac�  tion, he developed a painting style characterized by thick layering of pig�  ment, violent colour and brushwork, and crude, reductive figures. His</p><p>figurative sculptures are executed in metal and wood. He painted portraits  of jazz musicians and a number of public works, including a mural in the  Paris UNESCO building.</p><p>appendix in full vermiform appendix Vestigial hollow tube  attached to the cecum of the large intestine. The human appendix, usually  3-4 in. (8-10 cm) long and less than 0.5 in. (1.3 cm) wide, has no diges�  tive function. Its muscular walls expel their own mucous secretions or  any intestinal contents that enter it. Blockage of the opening may prevent  expulsion and cause appendicitis: fluids collect, bacteria propagate, and  the appendix becomes distended and inflamed; tissue in the appendix  begins to die, and the organ may burst, causing peritonitis. Its symptoms  may begin with moderate pain in the upper abdomen, about the navel, or  all over the abdomen. Nausea and vomiting may then develop. The pain  may shift to the right lower abdomen. Fever is usually present but is sel�  dom high in the early phases. Differentiating acute appendicitis from other  causes of abdominal pain requires careful examination. Treatment is  removal of the appendix (appendectomy).</p><p>Appian Way Va-pe-3n\ Latin Via Appia. First and most famous of  the ancient Roman roads, running from Rome to Campania and southern  Italy. Begun in 312 bc by the censor Appius Claudius Caecus, the road  originally ran 132 mi (212 km) to ancient Capua; by 244 bc it extended  230 mi (370 km) to the port of Brundisium (Brindisi) in Italy�s heel. Built  of smoothly fitted blocks of lava on a heavy stone foundation, the road  provided a long-lasting surface for transporting merchandise to these sea�  ports (and thence by ship to Greece and the eastern Mediterranean).  Remains can be seen today outside Rome.</p><p>apple Fruit of the genus Malus, in the rose family, the most widely cul�  tivated tree fruit. Malus species are native to the temperate zones of both  hemispheres. They require a considerable period of dormancy, well-  drained soil, careful pruning in early years of growth, and a rigorous pest-  management program for mature trees. The apple is one of the pome  (fleshy) fruits. Apples at harvest vary widely in size, shape, colour, and  acidity, but most are fairly round and some shade of red or yellow. The  thousands of varieties fall into three broad classes: cider, cooking, and  dessert varieties. Varieties that ripen in late summer generally do not store  well, but those that ripen in late autumn may be stored for as long as a  year. The largest producers of apples are the U.S., China, France, Italy,  and Turkey. Eaten fresh or cooked in various ways, apples provide vita�  mins A and C, carbohydrates, and fibre.</p><p>Apple Computer, Inc. Microcomputer design and manufacturing  company, the first successful personal-computer company. It was founded  in 1976 by Steven P. Jobs and Stephen G. Wozniak, whose first computer  was manufactured in the Jobs family�s garage. The Apple II (1977), with  its plastic case and colour graphics, launched the company to success,  earning Apple over $100 million by 1980, the year the company first  offered stock to the public. The 1981 introduction of IBM�s PC, running  a Microsoft Corp. operating system, marked the beginning of long-term  competition for Apple in the personal-computer market. The Macintosh,  introduced in 1984, was the first personal computer to use a graphical user  interface and a mouse. The �Mac� initially sold poorly, and Jobs left the  company in 1985, but eventually it found its niche in the desktop pub�  lishing market. Meanwhile, Microsoft�s Windows operating system  eroded Apple�s market share. Apple recalled Jobs in 1997. He returned  the company to profitability by introducing more innovative products,  such as the iMac. Apple introduced iTunes, software for playing music  that has been converted to the MP3 format, and the iPod portable MP3  music player in 2001; in 2003 the company began selling downloadable  copies of major record company songs in MP3 format over the Internet.</p><p>apple scab Disease of apple trees caused by the fungus Venturia  inaequalis , producing dark blotches or lesions on the leaves, fruit, and  sometimes young twigs. Affected plants may drop their fruit prematurely,  resulting in potentially high crop losses. Apple scab is found wherever  apples are grown but is most severe where spring and summer are cool  and moist. All apple species are affected. Regular spraying with fungicides  is the most effective method of controlling the disease.</p><p>Appleseed, Johnny orig. John Chapman (b. Sept. 26, 1774,  Leominster, Mass.�d.

Intelligence testing, legal problems, indus�  trial efficiency, motivation, and delinquency were among the first areas of  application in the early 20th century. World Wars I and II fostered work  on vocational testing, teaching methods, evaluation of attitudes and  morale, performance under stress, propaganda and psychological warfare,  and rehabilitation. The aviation and aerospace industries were important  for the development of engineering psychology, the study of human-  machine relationships. Other areas include consumer psychology, school  psychology, and community psychology.

Known from antiquity,  apprenticeship became prominent in medieval Europe with the emergence  of the craft guilds. The standard apprenticeship lasted seven years. Dur�  ing the Industrial Revolution a new kind of apprenticeship developed in  which the employer was the factory owner and the apprentice, after a  period of training, became a factory worker. The increasing need for  semiskilled workers led to the development of vocational and technical  schools in Europe and the U.S., especially after World War II.

The most common variety of gem beryl, it occurs  in pegmatites, in which it forms much larger and clearer crystals than emer�  ald, the dark green variety of beryl. Aquamarine occurs in Brazil, which  is the chief source, and in such other sites as the Ural Mountains, Mada�  gascar, Sri Lanka, India, and Maine, New Hampshire, Connecticut, North  Carolina, and Colorado in the U.S. Heat treatment is commonly used to  improve the colour of gem beryls.</p><p>aquarium Receptacle for maintaining aquatic organisms, either fresh�  water or marine, or a facility in which a collection of aquatic organisms  is displayed or studied. The first display aquarium opened in Regent�s  Park, England, in 1853. Many of the world�s principal cities now have  public aquariums as well as commercial ones; other aquarium facilities  serve chiefly as research institutions. Regardless of size�whether a small  one-gallon jar or a huge million-gallon tank�aquariums must be con�  structed with care; many substances, especially plastics and adhesives,  that are nontoxic to humans are toxic to water-breathing animals. The pri�  mary requirement for maintaining aquatic organisms is water quality.</p><p>Aquarius (Latin: �Water carrier�) In astronomy, the constellation lying  between Capricorn and Pisces; in astrology, the 11th sign of the zodiac,  governing approximately the period January 20-February 18. It is usually  represented as a man pouring a stream of water out of a jug, probably  because in ancient times the rising of Aquarius coincided in the Middle  East with the annual arrival of floods or rainfall. In the astrological con�  cept called the Great Year�the 25,000-year period it takes the earth to  pass through the influence of the entire zodiac�the early 19th century  was the beginning of the Age of Aquarius.</p><p>aquatint Method of etching that produces finely granulated tonal areas  rather than lines, so that finished prints often resemble watercolour or  wash drawings. A copper plate is exposed to acid through a layer of  granulated resin or sugar, which yields a finely speckled gray tone when  the plate is inked and printed. The texture and depth of tone are controlled  by the strength of the acid baths and the length of time the plate is exposed  to them. Aquatint became the most popular method of producing toned  prints in the late 18th century; its most notable practitioner was Francisco  Goya. In the 19th century Edgar Degas and Camille Pissarro experimented  with it, and in the 20th century the sugar aquatint was employed by Pablo  Picasso, Georges Rouault, and Andre Masson.</p><p>aquavit \'a-kw9-,vet\ (from Latin aqua vitae , �water of life�) Scandi�  navian clear distilled liquor flavoured with caraway seeds. Distilled from  a fermented potato or grain mash, filtered with charcoal, and usually  bottled without aging, aquavit has an alcohol content of 42^45% by vol�  ume. Most aquavits are sweet and spicy. It is usually served chilled and  unmixed, in small glasses.</p><p>aqueduct Conduit built to carry water from its source to a main distri�  bution point. Ancient Rome�s aqueduct system, an extraordinary feat of  engineering, brought water to the city from as far as 57 mi (92 km) away.  Only a portion of the Roman aqueducts utilized the familiar stone arch;  most were underground conduits made of stone or terra-cotta pipe. Modern  aqueduct systems employ cast iron or steel.

The rocks contain  water-filled pores that, when connected, allow water to flow through their  matrix. A confined aquifer is overlain by a rock layer that does not trans�  mit water in any appreciable amount or that is impermeable. There prob�  ably are few truly confined aquifers. In an unconfined aquifer the upper  surface (water table) is open to the atmosphere through permeable over-  lying material. An aquifer also may be called a water-bearing stratum,  lens, or zone.</p><p>Aquinas Vs-'kwI-nosV Saint Thomas (b. 1224/25, Roccasecca, near  Aquino, Terra di Lavoro, Kingdom of Sicily�d. March 7, 1274, Fos-  sanova, near Terracina, Latium, Papal States; canonized July 18, 1323;  feast day January 28, formerly March 7) Foremost philosopher and theo�  logian of the Roman Catholic church. Born of noble parents, he studied at  the University of Naples, joined the Dominicans, and taught at a Domini�  can school at the University of Paris. His time in Paris coincided with the  arrival of Aristotelian science, newly discovered in Arabic translation; his  great achievement was to integrate into Christian thought the rigours of  Aristotle�s philosophy, just as the early Church Fathers had integrated Pla�  to�s thought in the early Christian era. He held that reason is capable of</p><p>operating within faith; while the philosopher relies solely on reason, the  theologian accepts faith as his starting point and then proceeds to conclu�  sion through the use of reason. This point of view was controversial, as  was his belief in the religious value of nature, for which he argued that to  detract from the perfection of creation was to detract from the creator. He  was opposed by St. Bonaventure. In 1277, after his death, the masters of  Paris condemned 219 propositions, 12 of them Thomas�s. He was never�  theless named a Doctor of the Church in 1567 and declared the champion  of orthodoxy during the modernist crisis at the end of the 19th century. A  prolific writer, he produced more than 80 works, including Summa contra  Gentiles (1261�64) and Summa theologica (1265-73). See also Thomism.</p><p>Aquino \9-'ke-no\, (Maria) Corazon orig. Maria Corazon  Cojuangco (b. Jan. 25, 1933, Manila, Phil.) President of the Philippines  (1986-92). Born into a politically prominent family, she married Benigno  Simeon Aquino, Jr. (1932-83), who became the most prominent oppo�  nent of Pres. Ferdinand Marcos. Benigno was assassinated in 1983 on his  return from exile, and Corazon became the opposition candidate for presi�  dent in 1986. Though Marcos was officially reported the winner, there  were widespread allegations of voting fraud; high officials in the military  supported Aquino, and Marcos fled. As president, Aquino introduced a  hugely popular constitution. Over time her popularity declined amid  charges of corruption and economic injustice.</p><p>Aquitaine Historical region, southwestern France. It was roughly  equivalent to Aquitania, the Roman division of southwestern Gaul, which  consisted of the area between the Pyrenees Mountains and the Garonne  River. Conquered by Clovis in ad 507, it was later made a subkingdom by  Charlemagne in the 8th century. After the Carolingian decline, it became  a powerful duchy, which by the 10th century controlled much of France  south of the Loire. It passed to the Capetian line when Eleanor of Aquita�  ine married Louis VII (1137); on her second marriage, to Henry II of England  (1152), it passed to the English Plantagenets. The name Guyenne, a cor�  ruption of Aquitaine, came into use in the 10th century, and the subse�  quent history of Aquitaine is merged with that of Gascony and Guyenne.</p><p>AR-15 See Ml 6 rifle</p><p>Ara Pads Va-ra-'pa-sis\ (Augustae) Latin "Augustan Altar of  Peace" State monument built by Caesar Augustus in Rome�s Campus  Martius (13-9 bc) to commemorate his victorious return from Spain and  Gaul.

Its lavish  sculptural decoration is among the finest examples of Roman art; reliefs  representing the ceremonial procession at the altar�s dedication are the  first in Western art that can strictly be called documentary, showing iden�  tifiable individuals in a contemporary event.</p><p>Arab Any member of the ARABic-speaking peoples native to the Middle  East and North Africa. Before the spread of Islam in the 630s, the term  referred to the largely nomadic Semitic peoples of the Arabian Peninsula;  it came to apply to Arabic-speaking peoples from Africa�s Mauritanian  and Moroccan coasts east to Iraq and the Arabian Peninsula and south to  The Sudan after their acceptance of Islam. Traditionally, some Arabs are  desert-dwelling pastoral nomads (see Bedouin), whereas others live by  oases and in small, isolated farming villages. While most Arabs are Mus�  lims, some are Christian. The term has also been used in a political sense  by Arab nationalists to describe a greater sociolinguistic or ethnic ideal  (�the Arab nation�). See also Pan-Arabism.</p><p>Arab-lsraeli wars Series of military conflicts fought between various  Arab countries and Israel (1948�49, 1956, 1967, 1969-70, 1973, and  1982). The first war (1948-49) began when Israel declared itself an inde�  pendent state following the United Nations� partition of Palestine. Protest�  ing this move, five Arab countries�Egypt, Iraq, Jordan, Lebanon, and  Syria�attacked Israel. The conflict ended with Israel gaining consider�  able territory. The 1956 Suez Crisis began after Egypt nationalized the Suez  Canal. A French, British, and Israeli coalition attacked Egypt and occu�  pied the canal zone but soon withdrew under international pressure. In the  Six-Day War of 1967, Israel attacked Egypt, Jordan, and Syria. The war  ended with the Israel occupying substantial amounts of Arab territory. An  undeclared war of attrition (1969-70) was fought between Egypt and  Israel along the Suez Canal and ended with the help of international  diplomacy. Egypt and Syria attacked Israel in 1973 (the Yom Kippur War),  but, despite early Arab success, the conflict ended inconclusively. In 1979  Egypt made peace with Israel. In 1982 Israel invaded Lebanon in order  to expel Palestinian guerrillas based there.

It initially comprised Egypt, Syria,  Lebanon, Iraq, Transjordan (now Jordan), Saudi Arabia, and Yemen; join�  ing later were Libya, Sudan, Tunisia, Morocco, Kuwait, Algeria, Bahrain,  Oman, Qatar, the United Arab Emirates, Mauritania, Somalia, the Pales�  tine Liberation Organization, Djibouti, and Comoros. The league�s original  aims were to strengthen and coordinate political, cultural, economic, and  social programs and to mediate disputes; a later aim was to coordinate  military defense. Members have often split on political issues; Egypt was  suspended for 10 years (1979-89) following its peace with Israel, and the  Persian Gulf War (1990-91) also caused deep rifts.

The word was first  used in the 15th or 16th century  when Europeans became interested  in the Islamic arts, but the motif itself  was derived from Hellenistic crafts�  men in Asia Minor. Arabesques were  also applied to the decoration of illu�  minated manuscripts, walls, furni�  ture, metalwork, pottery, stonework,  majolica, and tapestry from the  Renaissance to the 19th century.</p><p>Arabia See Arabian Peninsula</p><p>Arabian Desert Desert region,</p><p>Arabian Peninsula. It covers about  900,000 sq mi (2,330,000 sq km),  occupying nearly the entire penin�  sula. It lies largely within Saudi Ara�  bia but large portions extend into  Jordan, Iraq, Kuwait, Qatar, the  United Arab Emirates, Oman, and  Yemen. Its relief is broken by a num�  ber of mountain ranges, with eleva�  tions reaching as high as 12,000 ft (3,700 m), and it is bounded on three  sides by high escarpments. At least one-third of the desert is covered by  sand, including the Rub' al-Khali, considered to have one of the most  inhospitable climates on Earth. There are no perennial bodies of water,  though the Tigris-Euphrates river system lies to the northeast and the Wadi  Hajr is located to the south, in Yemen. Humans have inhabited the area  since Pleistocene times.</p><p>Arabian horse Earliest improved breed of horse, valued for its speed,  stamina, beauty, intelligence, and gentleness. Its long history has been  obscured by legend, but it was developed in Arabia by the 7th century ad.  It has contributed its qualities to most modern breeds of light horses. It  is compact and relatively small, with a small head, protruding eyes, wide  nostrils, marked withers, and a short back. Its average height is about 15  hands (60 in. [152 cm]), its average weight 800-1,000 lbs (360-450 kg).  Though many colours are possible, gray is the most common.</p><p>Arabian Nights' Entertainment See The Thousand and One Nights</p><p>Arabian Peninsula or Arabia Peninsular region, southwest Asia.  With its offshore islands, it covers about 1 million sq mi (2.6 million sq  km). Constituent countries are Bahrain, Kuwait, Oman, Qatar, United  Arab Emirates, Yemen, and, the largest, Saudi Arabia. It is generally arid  and is covered almost entirely by the Arabian Desert. The modem economy  is dominated by the production of petroleum and natural gas. The world�s  largest proven reserves of those minerals are in the Arabian Peninsula. Its  political consolidation was begun by the Prophet Muhammad, and it was  the centre of the orthodox caliphate until 661, when that office passed to  the Umayyad dynasty in Damascus. After 1517 much of the region was  dominated by the Ottoman Empire, though the peninsula�s people, who had  remained largely tribal and nomadic, revolted repeatedly until the World  War I (1914-18), when the Ottoman Empire dissolved. Thereafter, indi�  vidual nation-states followed their own histories, though many maintained  close ties with European powers such as the United Kingdom.</p><p>Arabian religions, ancient Polytheistic religions of Arabia prior to  the rise of Islam. Most of the deities of the Arab tribes were sky gods,  associated with heavenly bodies such as the Sun and Moon, and they had  the power to ensure fecundity, protection, or revenge. At the head of the  southern Arabian pantheon was 'Athtar, a god of thunderstorms and rain.  Each kingdom also had a national deity, of whom the nation called itself  the progeny. Sanctuaries were carved in rock on high places and held a  baetyl (�raised stone�) or statue of the god in an open-air enclosure,  accessible only to ritually clean persons. In northern Arabia they included  a walled enclosure with a covered or enclosed altar, similar to the Mus�  lim Ka'bah. Libations, animal sacrifices, and other offerings were made to  the gods, and priests interpreted oracles and performed divination. Wor�  shipers made yearly pilgrimages to important shrines, participating in rites  that included purification, the wearing of ritual clothing, sexual absti�  nence, abstention from shedding blood, and circuits performed around the  sacred object.</p><p>Arabian Sea Northwestern part of the Indian Ocean, lying between  India and the Arabian Peninsula. It has an area of about 1,491,000 sq miles  (3,862,000 sq km) and an average depth of 8,970 feet (2,734 m). The Gulf  of Oman connects it with the Persian Gulf via the Strait of Hormuz, while  the Gulf of Aden connects it with the Red Sea via the Strait of Mandeb.  The Indus is the principal river draining into the Arabian Sea. Socotra,  Lakshadweep, and other islands lie within it. Chief ports are Mumbai (Bom�  bay), India; Karachi, Pak.; and Aden, Yemen. The sea has been part of the  principal trade route between Europe and India for centuries.</p><p>Arabic alphabet Script used to write Arabic and a number of other  languages whose speakers have been influenced by Arab and Islamic cul�  ture. The 28-character Arabic alphabet developed from a script used to  write Nabataean Aramaic. Because Arabic had different consonants than  Aramaic, diacritical dots came to be used to eliminate ambiguous read�  ings of some letters, and these remain a feature of the script. Arabic is  written from right to left. The letters denote only consonants, though the  symbols for w, y, and (historically) the glottal stop do double duty as  vowel letters for long u, i, and a. Additional diacritics, representing short  vowels (or the lack thereof), case endings, and geminate (duplicate) con�  sonants, are normally employed only for the text of the Qur�an, for prim�  ers, or in instances where the reading might otherwise be ambiguous.  Because Arabic script is fundamentally cursive, most letters have slightly  different forms depending on whether they occur in the beginning, middle,  or end of a word. Non-Semitic languages for which some version of the  Arabic alphabet has been or is used include Persian, Kurdish, Pashto, Urdu,  some Turkic languages, Malay, Swahili, and Hausa. The Maltese language  is the only form of Arabic to be written in the Latin alphabet.</p><p>Arabic language Ancient Semitic language whose dialects are spoken  throughout the Middle East and North Africa. Though Arabic words and  proper names are found in Aramaic inscriptions, abundant documentation  of the language begins only with the rise of Islam, whose main texts are  written in Arabic. Grammarians from the 8th century on codified it into  the form known as Classical Arabic, a literary and scribal argot that dif�  fered markedly from the spoken vernacular. In the 19th-20th centuries,  expansion of Classical Arabic�s stylistic range and vocabulary led to the  creation of Modern Standard Arabic, which serves as a lingua franca  among contemporary Arabs. However, Arabic speakers, who number  roughly 200 million, use an enormous range of dialects, which at their  furthest extremes are mutually unintelligible. Classical Arabic remains an  important cultural and religious artifact among the non-Arab Islamic com�  munity. See also Arabic alphabet.</p><p>Arabic literary renaissance (19th-century) Movement to develop  a modern Arabic literature. Inspired by contacts with the West and a  renewed interest in classical Arabic literature, it began in Egypt with Syr�  ian and Lebanese writers who sought the freer environment there, and it  spread to other Arab countries as a result of the dismemberment of the  Ottoman Empire after World War I and the coming of independence after  World War II. Its success in altering the direction of Arabic literature is  related to the spread and modernization of education and the emergence  of an Arabic press.</p><p>Arabic philosophy or Islamic philosophy Doctrines of the Ara�  bic philosophers of the 9th-12th century who influenced medieval Scho�  lasticism in Europe. The Arabic tradition combines Aristotelianism and  Neoplatonism with other ideas introduced through Islam. Influential think�  ers include the Persians al-KiNDi, al-FARABi, and Avicenna, as well as the</p><p>Arabesque decoration on the dome of  the Madar-i-Shah madrasah ("school")  built by Husayn I, early 18th century, at  Esfahan, Iran</p><p>RAY MANLEY-SHOSTAL ASSOC./EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>94 I Arachne &#x25BA; Aramaic</p><p>Spaniard Averroes, whose interpretations of Aristotle were taken up by  both Jewish and Christian thinkers. Muslims, Christians, and Jews par�  ticipated in the Arabic tradition and separated themselves according to  philosophic rather than religious doctrines. When the Arabs dominated  Spain, the Arabic philosophic literature was translated into Hebrew and  Latin; this contributed to the development of modern European philoso�  phy. In Egypt around the same time, the Arabic tradition was developed  by Moses Maimonides and Ibn Khaldun.</p><p>Arachne \o-'rak-ne\ In Greek mythology, the daughter of the dyer Idmon  of Colophon. She was a weaver who acquired such skill that she ventured  to challenge Athena to a contest. Athena wove a tapestry showing the gods  in majesty, while Arachne depicted them in their amorous adventures.  Enraged at the perfection of her rival�s work, Athena tore it to shreds,  whereupon Arachne hanged herself. Out of pity Athena loosened the rope,  which became a cobweb, and Arachne was changed into a spider.</p><p>arachnid \o-'rak-nid\ Any member of the class Arachnida, primarily  carnivorous arthropods having a well-developed head, a hard external  skeleton, and four pairs of walking legs. Spiders and scorpions have a seg�  mented body, but daddy longlegs, ticks, and mites do not. Arachnids range  in size from tiny mites (0.003 in. [0.08 mm] long) to the 8-in. (21-cm)  black scorpion of Africa. As arachnids grow, they molt several times (see  molting). Most are unable to digest food internally; instead, they inject  their prey with digestive fluids and suck the liquefied remains. Arachnids  are found worldwide in nearly every habitat. Most groups are free-living,  but some mites and ticks are parasitic and can carry serious diseases of  animals and humans. Venomous spiders and scorpions also may pose a  danger to humans. However, most arachnids are harmless and prey on  insect pests.</p><p>Arachosia X.ar-o-'ko-zhoV Ancient province, eastern Persian empire.

Muhammad �Abd al-Ra�uf  al-Qudwah al-Husaynl (b. August 1*929�d. Nov. 11, 2004, Paris,  France) Palestinian leader. The date and place of his birth are disputed.  A birth certificate registered in Cairo, Egypt, gives Aug. 24, 1929, but  some sources support his claim to have been born in Jerusalem on Aug.  4, 1929. He graduated from the University of Cairo as a civil engineer  and served in the Egyptian army during the 1956 Suez Crisis. That year,  working as an engineer in Kuwait, he cofounded the guerrilla organiza�  tion Fatah, which became the leading military component of the Palestine  Liberation Organization (PLO), which he led from 1969. In 1974 the PLO  was formally recognized by the UN, and 'Arafat became the first leader  of a nongovernmental organization to address the UN. In 1988 he  acknowledged Israel�s right to exist, and in 1993 he formally recognized  Israel during direct talks regarding land controlled by Israel since the Six-  Day War. In 1994 he shared the Nobel Prize for Peace with Israelis Yitzhak  Rabin and Shimon Peres. In 1996 he became president of the new Pales�  tinian Authority.</p><p>Aragon Var-9-,gan\ Spanish Aragon Autonomous community (pop.,  2001: 1,204,215), northeastern Spain. Roughly coextensive with the his�  torical kingdom of Aragon, it occupies an area of 18,425 sq mi (47,720  sq km). Its capital is Zaragoza (Saragossa). Mountains, including the  Pyrenees, dominate the relief north and south of the Ebro River, which  bisects Aragon. Established in 1035 by Ramiro I, the historical kingdom  grew as land was retaken from the Moors: Zaragoza, the capital of the  Almoravid kingdom, fell to Alfonso I of Aragon in 1118, and the recon�  quest of present-day Aragon was completed by the late 12th century. In  the 13th�15th centuries it came to rule Sicily, Sardinia, Naples, and  Navarra. In the 15th century Ferdinand married Isabella of Castile, uniting  the kingdoms of Aragon and Castile and forming the nucleus of modern  Spain. The old kingdom of Aragon survived as an administrative unit until  1833, when it was divided into provinces. Agriculture, mining, and indus�  try, the latter concentrated at Zaragoza, are economically important.</p><p>Aragon \a-ra-'go n \, Louis orig. Louis Andrieux (b. Oct. 3, 1897,  Paris, Fr.�d.

From 1927 he was  increasingly a political activist and spokesman for communism, which  resulted in a break with the Surrealists. Among his works are the novel  tetralogy Le Monde reel, 4 vol. (1933-44), describing the class struggle</p><p>of the proletariat; the huge novel Les Communistes, 6 vol. (1949-51);  novels of veiled autobiography; and volumes of poems expressing patrio�  tism and love for his wife.

In the Russo-Swedish War of 1808�  09, he personally compelled the reluctant Russian forces to cross the fro�  zen Gulf of Finland to attack the Aland Islands, which ultimately resulted  in Sweden�s cession of Finland to Russia. He was Alexander I�s chief  military adviser in the Napoleonic Wars. After the wars, he supervised the  management of Russia�s domestic matters with brutal and ruthless effi�  ciency, which caused the period (1815-25) to be known as Arakcheyevsh-  china, but also took part in the emancipation of serfs in the Baltic  provinces and created a system of military-agricultural colonies.</p><p>Araks River See Aras River</p><p>Aral Sea Large salt lake between Kazakhstan and Uzbekistan. It once  covered some 26,300 sq mi (68,000 sq km) and was the fourth largest  inland body of water in the world, but diversion of the waters of the Syr  Darya and Amu Darya rivers for irrigation has led to an overall reduction  of its surface area by more than half since 1960. Its volume has been  reduced drastically, which has led to an increase in salinity. The soil of  the dried-up lake bed has been found to contain salts and other toxic sub�  stances.</p><p>Aram \'ar-9m\ Ancient country, Middle East, southwestern Asia. It  extended eastward from the Anti-Lebanon Mountains to beyond the Euph�  rates River. It was named for the Aramaeans, who emerged from the Syr�  ian desert to invade Syria and Upper Mesopotamia (c. 11th century bc) and  who built numerous city-kingdoms, including Damascus. It lends its name  to the Aramaic language.</p><p>Aramaean \,ar-9-'me-9n\ A member of any people belonging to a con�  federacy of tribes that migrated from the Arabian Peninsula to the Fertile  Crescent c. 1500-1200 bc. Among them were the biblical matriarchs Leah  and Rachel, wives of Jacob. The Aramaic language and culture spread  through international trade. They reached a cultural peak during the 9th-  8th centuries bc. By 500 bc, Aramaic had become the universal language  of commerce, culture, and government throughout the Fertile Crescent  and remained so through the time of Jesus and into the 7th century in some  areas.</p><p>Aramaic \,ar-9-'ma-ik\ language Semitic language originally spoken  by the ancient Aramaeans.

The period 600-200 bc saw a dramatic expansion of  Aramaic, leading to the development of a standard form known as Impe�  rial Aramaic. In later centuries, as �Standard Literary Aramaic,� it became  a linguistic model. Late (or Classical) Aramaic (c. ad 200-1200) has an  abundant literature, both in Syriac and in Mandaic (see Mandaeanism).  With the rise of Islam, Arabic rapidly supplanted Aramaic as a vernacu�  lar in South Asia. Modern Aramaic (Neo-Aramaic) comprises West Neo-  Aramaic, spoken in three villages northeast of Damascus, Syria, and East  Neo-Aramaic, a group of languages spoken in scattered settlements of  Jews and Christians in southeastern Turkey, northern Iraq, and northwest�  ern Iran, and by modern Mandaeans in the Shatt Al-'Arab. Since c. 1900  persecution has forced most contemporary East Neo-Aramaic-speakers,  who number several hundred thousand, into diaspora communities around  the world.</p><p>Aramco \3-'ram-ko\ in full Arabian American Oil Company Oil</p><p>company founded by the Standard Oil Co. of California (Chevron) in  1933, when the government of Saudi Arabia granted it a concession. Other  U.S. companies joined after oil was found near Dhahran in 1938. In 1950  Aramco opened a pipeline from Saudi Arabia to the Mediterranean Sea  port of Sidon, Leb. It was closed in 1983 except to supply a refinery in  Jordan. A more successful pipeline, with a destination on the Persian Gulf,  was finished in 1981. In 1951 Aramco found the first offshore oil field in  the Middle East. In the 1970s and �80s, control gradually passed to the  Saudi Arabian government, which eventually took over Aramco and  renamed it Saudi Aramco in 1988.</p><p>Aran Islands \'ar-an\ Islands (pop., 2001: 543), Galway Bay, western  Ireland. The group of small islands, totaling about 18 sq mi (47 sq km),  includes Inishmore (or Aranmore), Inishmaan, and Inisheer. Their main  town is Kilronan on Inishmore.

Oct. 22, 1882, Budapest) Hungarian epic poet. His main work is the tril�  ogy of Toldi (1847), Toldi szerelme (1848-79), and Toldi esteje (1854).  Recounting the adventures of a 14th-century youth of great physical  strength, it was received with enthusiasm by a public craving a national  literature of quality in a language all could grasp. Other notable works  include a fragment of an epic poem, Bolond Istok (1850), and The Death  of King Buda (1864), the first part of a projected Hun trilogy. The Osz-  ikek, written just before his death, poignantly reflects his sense of unful�  fillment and isolation. He is considered Hungary�s greatest epic poet.</p><p>arap Moi, Daniel See Daniel arap Moi</p><p>Arapaho \3-'ra-p9-,ho\ North American Plains Indian peoples living  mostly in Oklahoma and Wyoming, U.S. They are believed to have once  lived in permanent villages in the eastern woodlands. Their language is  of Algonquian stock. Like other Plains groups, the Arapaho were  nomadic, living in tepees and depending on the buffalo for subsistence.  They split into northern and southern groups after 1830. They were highly  religious and practiced the sun dance. Their social organization included  age-graded military societies as well as men�s shamanistic societies. They  traded with the Mandan and Arikara and were often at war with the Shos�  hone, Ute, and Pawnee. A southern branch was long allied with the Chey�  enne and fought with them against Col. George Custer at Little Bighorn in  1876. In the 2000 U.S. census some 7,000 people claimed sole Arapahoe  descent.</p><p>Ararat \'ar-3-,rat\, Mount Turkish Agri Dagi Extinct volcanic mas�  sif, eastern Turkey. Located in Ago province, near the Iranian border,  Ararat has two peaks, Great Ararat, at 16,853 ft (5,137 m) the highest  point of elevation in Turkey, and Little Ararat, almost 13,000 ft (4,000  m). Ararat is traditionally associated with the mountain where Noah�s ark  came to rest at the end of the biblical Deluge. A village on its slopes at  the site where Noah is said to have built an altar was destroyed in an  earthquake in 1840.</p><p>Aras \a-'ras\ River or Araks \a-'raks\ River River in Turkey, Arme�  nia, Azerbaijan, and Iran. It rises in the mountains south of Erzurum, Tur�  key, and flows east to join the Kura River in Azerbaijan about 75 mi (120  km) from its mouth. Since a flood in 1897, a separate distributary of the  Aras has also emptied into the Caspian Sea.

He democratized Sicyon (251)  and, as leader of the Achaean League (in alternate years from 245), set up  democracies in league cities and helped free Athens from Macedonia  (229). Under him, the league opposed Sparta; with Macedonian help, it  defeated Aetolia (217). Aratus nevertheless defied the anti-Roman policy  of Philip V of Macedonia; his death, popularly linked to Philip, was more  likely caused by tuberculosis.</p><p>Araucanian Va-.raii-'ka-ne-onzV South American Indian people who are  now concentrated in the valleys and basins between the Bio Bio and Tolten  rivers in south-central Chile. When the Spanish cONQUiSTADORes arrived in  Chile, they encountered three Araucanian populations: the Picunche, who  were accustomed to Inca control; the Huilliche, who were too few and  scattered to resist the conquistadores; and the Mapuche, successful farm�  ers and artisans. The first two were soon assimilated, but the Mapuche  managed to resist Spanish and Chilean control for some 350 years. They  were subdued in the late 19th century and were settled on reservations;  they now live independently.</p><p>araucaria \ l ar-o- , kar-e-9\ Any pinelike coniferous plant (see conifer)  of the genus Araucaria (family Araucariaceae). Found in South America,  the Phoenix Islands, and Australia, araucaria trees are magnificent ever�  greens, with whorled branches and stiff, flattened, pointed leaves. Com�  mon species are the monkey puzzle tree and the Norfolk Island pine, often  grown as a houseplant. Several species are cultivated on the Pacific coast  of the U.S. and in southern Florida.

The Taino, an Arawak subgroup, were the first native peoples  encountered by Christopher Columbus on Hispaniola. The island Arawak  were wiped out by disease, but some mainland South American Arawak,  who inhabited northern and western areas of the Amazon River basin, sur�  vived conquest. At the turn of the 21st century, the Arawak lived mainly in  Guyana, where they represented about one-third of the Indian population.  Smaller numbers live in Suriname, French Guiana, and Venezuela.</p><p>Arawakan \,ar-3-'wa-k3n\ languages or Maipuran \ml-'pu-r9n\  languages Largest family of American Indian languages.

The son of a Swiss emigre, Arbenz joined  the leftist army officers who overthrew the dictator Jorge Ubico (1878�  1946) in 1944. Elected president in 1951, he made land reform his cen�  tral project. His efforts to expropriate idle land owned by the United Fruit  Co. and his alleged communist links led to an invasion sponsored by the  U.S. Central Intelligence Agency. When the army refused to defend Arbenz  against what appeared to be a superior force, he resigned and went into  exile, and the CIA installed the leader of the proxy army. Col.

Both sides  in the dispute usually must agree in advance to the choice of arbitrator  and certify that they will abide by the arbitrator�s decision. In medieval  Europe arbitration was used to settle disputes between merchants; it is  now commonly used in commercial, labour-management, and interna�  tional disputes. The procedures differ from those used in the courts, espe�  cially regarding burden of proof and presentation of evidence. Arbitration  avoids costly litigation and offers a relatively speedy resolution as well  as privacy for the disputants. The main disadvantage is that setting guide�  lines is difficult; therefore the outcome is often less predictable than a  court decision.

Arboriculture includes all  aspects of growing, maintaining, and identifying plants, arranging plant�  ings for their ornamental values, and removing trees. The well-being of  individual plants is the major concern of arboriculture, in contrast to such  related fields as forestry and agriculture, in which the major concern is the  welfare of a large group of plants as a whole.</p><p>arborvitae \,ar-b9r-'vl-te\ (Latin: �tree of life�) Any of six species  (genus Thuja) of resinous, evergreen ornamental and timber conifers of  the cypress family, native to North America and eastern Asia. Arborvitae  trees or shrubs have thin, scaling outer bark and fibrous inner bark; hori�  zontal or ascending branches; and flattened, spraylike branchlets with  scalelike leaves. The Oriental, or Chinese, arborvitae ( T. orientalis ), a  popular ornamental native to Asia, is a gracefully symmetrical shrub.  Arborvitae wood is soft and lightweight but very durable, fragrant, and  easily worked. The giant arborvitae ( T. plicata) is the most important  timber-producing species, but the wood of the American arborvitae ( T.  occidentalis) is also frequently used. False arborvitae ( Thujopsis dola-  brata) is closely related.</p><p>arbovirus X.ar-bo-'vI-rosX Any of a large group of viruses that develop  in arthropods (chiefly mosquitoes and ticks). The name derives from  �arthropod-borne virus.� The spheroidal virus particle is encased in a fatty  membrane and contains RNA; it causes no apparent harm to the arthro�  pod host. Arboviruses are transmitted by bites to vertebrate hosts, in which  they establish infections and complete their growth cycle; they include  the agents responsible for yellow fever and equine encephalitis.

The sister of the poet and critic Howard Nemerov, she worked as a fash�  ion photographer in the 1950s. From about 1955 to 1957 she studied with  documentary photographer Lisette Model. She published her first photo�  essay, for Esquire, in 1960. In the 1960s she began to explore the sub�  jects that would occupy her for much of her career: individuals living on  the outskirts of society and �normalcy,� such as nudists, transvestites,  dwarfs, and the mentally or physically handicapped. Her own evident  intimacy with the subjects of her photos resulted in images that engage  the sympathy and collusion of the viewer and elicit a strong response.  During this period she mastered her technique of using a square format  and flash lighting, which gives her work a sense of theatricality and sur�  realism. In 1971 Arbus committed suicide.</p><p>Arbuthnot Var-'both-notV John (b. April 1667, Inverbervie, Scot.�d.  Feb. 27, 1735, London, Eng.) Scot�  tish mathematician, physician, and  satirist.

He was a founding member  of the famous Scriblerus Club, which  aimed to ridicule bad literature and  false learning. He was also chief  contributor to and guiding spirit of  the Memoirs of Martinus Scriblerus  (written 1713-14), a mocking expo�  sure of pedantry that was written by  club members.</p><p>arbutus \ar-'byu-t3s\ Any of about  14 species (genus Arbutus) of broad�  leaved evergreen shrubs or trees, in  the heath family.

Initiated by Napoleon,  designed by Jean-Francois-Therese Chalgrin, and constructed in 1806-36,  the monument is 164 ft (50 m) high and 148 ft (45 m) wide. Decorative  relief sculptures celebrating Napoleon�s victorious military campaigns  were executed on the arch by Francois Rude, Jean-Pierre Cortot, and An�  toine Etex.</p><p>arc furnace Type of electric furnace in which heat is generated by an  arc between carbon electrodes above the surface of the material (com�  monly a metal) being heated. William Siemens first demonstrated the arc  furnace in 1879 at the Paris Exposition by melting iron in crucibles; hori�  zontally placed carbon electrodes produced an electric arc above the con�  tainer of metal. The first commercial arc furnace in the U.S. (1906) had  a capacity of four tons (3.6 metric tons) and was equipped with two elec�  trodes. Modern furnaces range in heat size from a few tons up to 400 tons  (360 metric tons), and the arcs strike directly into the metal bath from  vertically positioned, graphite electrodes to remelt scrap steel or refine  briquettes of direct-reduced iron ore.</p><p>arcade Series of arches, supported by columns or piers, joined together  end to end in a row.

See also colonnade.</p><p>Arcadia Ancient country, central Peloponnese, Greece. Mountainous and  landlocked, it was not overrun by the Dorians during their occupation of  Greece (1100-1000 bc). Its isolation and its pastoral character partly  explain why it was represented as a paradise in Greek and Roman bucolic  poetry. It was the scene of conflict during the War of Greek Independence  (1821-29). The modem Greek department of Arkadhfa is nearly coex�  tensive with the ancient country.</p><p>Arcadian League Confederation of ancient Greek city-states of Arca�  dia. Arcadian towns had been forced to ally with Sparta by 550 bc, and  most Arcadians remained faithful to Sparta during the Peloponnesian War  (431^-04 bc). In an effort to contain Sparta, Epaminondas of Thebes  founded the city-state of Megalopolis in 371-368 bc as the seat of the  Arcadian League. The League united the Arcadians for a few decades until  internal discord crippled their confederation.</p><p>Arcaro, Eddie orig. George Edward Arcaro (b. Feb. 19, 1916,  Cincinnati, Ohio, U.S.�d.

The masonry arch provides the  stepping stone from the post-and-beam system to the evolution of the vault,  and was first widely used by the Romans. Its construction depends on a  series of wedge-shaped blocks (voussoirs) set side by side in a semicir�  cular curve or along two intersecting arcs (as in a pointed arch). The cen�  tral voussoir is called the keystone, and the two points where the arch  rests on its supports are known as the spring points. An arch can carry a  much greater load than a horizontal beam of the same size and material,  because downward pressure forces the voussoirs together instead of apart.  The resulting outward thrust must be resisted by the arch�s supports.  Present-day lightweight monolithic (one-piece) arches of steel, concrete,  or laminated wood are highly rigid, and thereby minimize horizontal  thrust. See illustration opposite.</p><p>archaebacteria \,ar-ke-,bak-'tir-e-3\ Group of bacteria whose mem�  bers differ from the eubacteria in certain physical, physiological, and  genetic features (e.g., cell-wall components). Archaebacteria are aquatic  or terrestrial microorganisms that exhibit a diversity of shapes, including  spherical, rod-shaped, and spiral forms. They survive in various extreme  environments, including very hot or salty ones. Some require oxygen;  some do not. Some produce methane as an end product; others depend  on sulfur for their metabolism.</p><p>archaeology Scientific study of material remains of past human life  and activities. These include human artifacts from the very earliest stone  tools to the man-made objects that are buried or thrown away in the  present day. Archaeological investigations are a principal source of mod�  ern knowledge of prehistoric, ancient, and extinct cultures. The field  emerged as an academic discipline in the late 19th century, following  centuries of haphazard antiquarian collecting. Among the archaeologist�s  principal activities are the location, surveying, and mapping of sites and  the excavation, classification, dating, and interpretation of materials to  place them in historical context. Major subfields include classical archae�  ology, the study of ancient Mediterranean and Middle Eastern civiliza�  tions; prehistoric archaeology, or general archaeology; and historical  archaeology, the study of historic-period remains to augment the written  record.

It flour�  ished during the Late Jurassic period (159-144 million years ago). Fossil  specimens indicate that archaeopteryx ranged in size from as small as a  blue jay to as large as a chicken. Archaeopteryx shared anatomical char�  acteristics with both birds (well-developed wings and birdlike skull) and  theropod dinosaurs (well-developed teeth and a long tail).</p><p>Archangel See Arkhangelsk</p><p>archbishop In Christianity, a bishop who has jurisdiction, but not supe�  riority, over the other bishops in a province as well as episcopal author�  ity in his own diocese. Introduced as an honorary title in the Eastern  churches in the 4th century, the office did not become common in West�  ern churches until the 9th century. It is now most widely used in the  Roman Catholic and Eastern Orthodox churches. It is more rarely used  in Protestant denominations, though the Church of England has archbish�  ops of Canterbury and York, and the Lutheran churches of both Sweden  and Finland have an archbishop.</p><p>Archean \ar-'ke-on\ Eon or Archaean Eon or Archeozoic Eon</p><p>Older of the two divisions of Precambrian time.

As shown on the Roman arch, the first voussoir, or springer, rests  on the impost, at the top of the abutment or pier. The haunch, rising from the impost  to the crown (highest point), is defined by the inner curve, or intrados, and outer  curve, or extrados. The Roman arch, with its semicircular intrados, has a rise  exactly half the width of the span. Below it are shown examples of the curved arch  (left) and the pointed arch (right). The stilted arch has vertical sides. A Moorish arch  widens above the spring points. The trefoil arch's intrados has three indentations, or  foils. A Gothic arch is a pointed arch usually having two haunches of equal radii of  curvature. A Tudor arch has greater curvature near the springers than near the  point.

As the bow began to  be replaced by the gun as the principal weapon of warfare and the hunt  beginning in the 16th century, it increasingly became a sporting device.  By the mid-19th century, many archery clubs had sprung up in England  and the U.S. Competitions including target-shooting were held at the  Olympic Games in the early 20th century, but were then suspended until  1972. Other varieties of archery include field archery, or roving (a simu�  lation of hunting), and flight shooting (a distance event).</p><p>Arches National Park Preserve, eastern Utah, U.S. Located on the  Colorado River north of Moab, the preserve was established as a national  monument in 1929 and as a national park in 1971.

The park�s sandstone has been eroded into unusual  shapes, including Courthouse Towers, Fiery Furnace, and Devils Garden,  the site of Landscape Arch, at 306 ft (93 m) the longest freestanding natu�  ral rock bridge in the world.</p><p>archetype \'ar-ki-,tlp\ Primordial image, character, or pattern of cir�  cumstances that recurs throughout literature and thought consistently  enough to be considered universal. Literary critics adopted the term from  Carl Gustav Jung�s theory of the collective unconscious. Because arche�  types originate in pre-logical thought, they are held to evoke startlingly  similar feelings in reader and author. Examples of archetypal symbols  include the snake, whale, eagle, and vulture. An archetypal theme is the  passage from innocence to experience; archetypal characters include the  blood brother, rebel, wise grandparent, and prostitute with a heart of gold.</p><p>Archimedean screw N.ar-ko-'med-e-sM or Archimedes' screw</p><p>Machine for raising water, said to have been invented by Archimedes for  removing water from the hold of a large ship. One form consists of a cir�  cular pipe enclosing a helix and inclined at an angle of about 45�, with  its lower end dipped in the water; rotation of the device lifts the water in  the pipe. Other forms consist of a helix revolving in a fixed cylinder or a  helical tube wound around a shaft.</p><p>Archimedes V.ar-ko-'me-.dezX (b. c. 290-280 bc, Syracuse, Sicily�d.  212/211 bc, Syracuse) Legendary Greek inventor and mathematician. His  principal discoveries were the Archimedes screw, an ingenious device for  raising water, and the hydrostatic principle, or Archimedes' principle. His  main interests were optics, mechanics, pure mathematics, and astronomy.  Archimedes� mathematical proofs show both boldly original thought and a  rigour meeting the highest standards of contemporary geometry. His  approximation of n was not improved on until after the Middle Ages, and  translations of his works were important influences on 9th-century Arab  and 16th- and 17th-century European mathematicians. In his native city,  Syracuse, he was known as a genius at devising siege and countersiege  weapons. He was killed by a Roman soldier during the storming of the city.</p><p>Archimedes' principle Law of buoyancy, discovered by Archimedes,  which states that any object that is completely or partially submerged in  a fluid at rest is acted on by an upward, or buoyant, force. The magni�  tude of this force is equal to the weight of the fluid displaced by the object.  The volume of fluid displaced is equal to the volume of the portion of the  object submerged.</p><p>Archipenko X.ar-ko-'peq-koV Alexander (b. May 30, 1887, Kiev,  Ukr.�d. Feb. 25, 1964, New York, N.Y., U.S.) Ukrainian-U.S. sculptor.  In 1908 he moved to Paris to study at the Ecole des Beaux-Arts, and he  soon became active in radical circles such as the Cubist movement. He  began to explore the interplay between interlocking voids and solids and  between convex and concave surfaces, forming a sculptural equivalent to  Cubist paintings� overlapping planes and, in the process, revolutionizing  modern sculpture. About 1912 he introduced the concept of collage in  sculpture, and he went on to further defy tradition in his �sculpto-  paintings,� works in which he introduced painted colour to the intersect�  ing planes of his sculpture. In 1923 he moved to New York City, where  he worked and taught for most of his life.</p><p>architecture Art and technique of designing and building, as distin�  guished from the skills associated with construction. The practice of archi�  tecture emphasizes spatial relationships, orientation, the support of  activities to be carried out within a designed environment, and the  arrangement and visual rhythm of structural elements, as opposed to the</p><p>design of structural systems themselves (see civil engineering). Appropri�  ateness, uniqueness, a sensitive and innovative response to functional  requirements, and a sense of place within its surrounding physical and  social context distinguish a built environment as representative of a cul�  ture�s architecture.

Archives are  produced or received by a public, semipublic, institutional, or business  entity in the transaction of its affairs and are preserved by it or its suc�  cessors. The modern institution of archives and archival administration  dates from the late 18th century, when national and departmental archives  were established in France. In the U.S. the National Archives was estab�  lished in 1934 to house the retired records of the national government; the  Federal Records Act of 1950 authorized regional records repositories.  Each U.S. state has its own archival agency. Archivists in the 20th cen�  tury increasingly handled records involving new technologies, such as  computer-kept records and motion pictures, as well as the records of busi�  nesses, institutions, and individuals.</p><p>arch on In ancient Greece, the chief magistrate or magistrates in a city-  state, from the Archaic period onward. In Athens, nine archons divided  state duties: the archon eponymous headed the boule and Ecclesia, the  polemarch commanded troops and presided over legal cases involving  foreigners, the archon basileus headed state religion and the Areopagus,  and the six remaining archons handled various judicial matters. At first  only elected aristocrats could serve, and their term was for life; later, terms  were limited to a year. Archons were chosen by a combination of elec�  tion and lot. In the 5th century bc the authority of the archons declined  as elected generals assumed most of their powers.</p><p>Archon \'ar-,kan\ In Gnosticism, any of various world-governing pow�  ers created with the material world by the Demiurge. Because the Gnos�  tics regarded the material world as evil or as the product of error, Archons  were considered forces of evil. Seven or 12 in number, they were iden�  tified with the seven planets of antiquity or the 12 signs of the ZODIAC.  They were thought to have imprisoned the divine spark of human souls  in material creation. The gnosis sent from the realms of divine light  through Jesus enabled Gnostic initiates to pass through the spheres of the  Archons into the realms of light.</p><p>archosaur Var-k3-,s6r\ Any of the various advanced reptiles in the sub�  class Archosauria (�ruling reptiles�), including all thecodonts, pterosaurs,  dinosaurs, birds, and crocodilians. The first known archosaurs appeared  242-227 million years ago during the Triassic Period. All early archosaurs  possessed an ankle specialization that aided in upright posture, and most  had long hindlegs and short forelimbs. Unlike the teeth of earlier reptiles,  which were set in a shallow groove, the teeth of archosaurs were (and  are) set in sockets.</p><p>Archytas \ar-'ki-tas\ (fl. 400-350 bc, Tarentum, Magna Graecia) Greek  scientist, philosopher, and Pythagorean mathematician. Archytas is some�  times called the founder of mathematical mechanics. Plato, a close friend,  made use of his work in mathematics, and there is evidence that Euclid  borrowed from Archytas for Book VIII of the Elements. An influential  public figure, he served seven years as commander in chief of his city,  Tarentum (now Taranto, Italy).</p><p>Arcimboldo V.ar-chem-'bol-doV Giuseppe (b. c. 1527, Milan�d.  1593, Milan) Italian painter. He began his career as a painter and designer  of stained-glass windows for Milan Cathedral. In 1562 he moved to Pra�  gue and became court painter to the emperors Ferdinand I and Rudolf II.  He also painted scenery for the court theatre and became skillful at illu-  sionistic imagery containing allegorical meanings, puns, and jokes. He is  known for his eccentric and grotesque Mannerist compositions of fruits,  vegetables, animals, landscapes, and implements arranged to resemble  human forms. The style was regarded as being in poor taste until the Sur�  realists revived the art of visual punning in the 1920s.

Its short, rounded ears and  short muzzle reduce its body area exposed to heat loss, and it has fur-  covered soles. It is 20-24 in. (50-60 cm) long (excluding the 12-in., or  30-cm, tail) and weighs 7-17 lbs (3-8 kg). It has two colour phases. Indi�  viduals in the white phase are grayish brown in summer and white in win�  ter; those in the blue phase (blue foxes of the fur trade) are grayish in  summer and gray-blue in winter. The Arctic fox dwells in burrows and  feeds on any available animal or vegetable material.</p><p>Arctic National Park, Gates of the See Gates of the Arctic  National Park</p><p>Arctic Ocean Ocean centring approximately on the North Pole. Small�  est of the world�s oceans, it is almost completely surrounded by the land-  masses of Eurasia and North America, and it is distinguished by a cover  of ice. Lands in it and adjacent to it include Point Barrow in Alaska, the  Arctic Archipelago, Greenland, Svalbard, Franz Josef Land, and northern  Siberia. The ocean covers about 5,440,000 sq mi (14,090,000 sq km) and  reaches a maximum depth of about 18,000 ft (5,500 m). Its marginal seas  include the Barents, Beaufort, Chukchi, East Siberian, Greenland, Kara,  Laptev, and White seas. Areas within the Arctic Circle were first explored  beginning in the 9th century by the Norse. In the 16th� 17th centuries  explorers searching for the Northwest Passage reached the area; Martin  Frobisher discovered the southern part of Baffin Island (1576-78), and  Henry Hudson navigated the eastern coast of Hudson Bay (1610-11). Later  explorers included Roald Amundsen, Fridtjof Nansen, Robert E. Peary, and  Richard E. Byrd. Development of the area�s natural resources was spurred  by the discovery of oil in Alaska in the 1960s. Virtually all of the Arctic  has now been mapped.

While at Mar�  burg she began a romantic relationship with her teacher Martin Heidegger.  Following the Nazi takeover of Germany in 1933, Arendt, who was Jew�  ish, fled to Paris, where she became a social worker, and then to New  York City in 1941. Her major work, Origins of Totalitarianism (1951),  traced totalitarianism to 19th-century anti-Semitism, imperialism, and the dis�  integration of the traditional nation-state. Her highly controversial book  Eichmann in Jerusalem (1963) argued that the Nazi war criminal Adolf  Eichmann was not inwardly wicked or depraved but merely �thoughtless�;  his role in the extermination of the Jews thus epitomized the fearsome  �banality of evil� that had swept across Europe at the time. Resuming  contact with Heidegger in 1950, she claimed that his involvement with  the Nazis had been the �mistake� of a great philosopher. She taught at the  University of Chicago (1963-67) and thereafter at the New School for  Social Research in New York City.</p><p>Areopagus \,ar-e-'a-p9-g3s\ Supreme tribunal of ancient Athens.

Population (2005  est.): 38,592,000. Capital: Buenos Aires. The people are mostly of Euro-</p><p>Catholic [official]; also Protestant); also Islam, Judaism. Currency: Argen�  tine peso. Argentina can be divided into four general regions: the North,  the Pampas, Patagonia, and the Andes Mountains. The subtropical plains  in the northeast are divided by the Parana River into Mesopotamia to the  east and Gran Chaco to the west and north. The Pampas, south and west  of the Parana, is one of the world�s most productive agricultural areas and  the country�s most populous region. Patagonia lies south of the Colorado  River. The Argentine Andes include the continent�s highest peak, Mount  Aconcagua. Argentina�s hydrology is dominated by rivers that include  the Parana, Uruguay, and Pilcomayo, which drain into the Rio de la Plata.  Argentina has a developing economy based largely on manufacturing and  agriculture; it is Latin America�s largest exporter of beef and beef prod�  ucts. It is a republic with two legislative houses; the head of state and  government is the president. Little is known of the indigenous population  before the Europeans� arrival. The area was explored for Spain by Sebas�  tian Cabot beginning in 1526; by 1580 Asuncion, Santa Fe, and Buenos  Aires had been settled. Early in the 17th century it was attached to the  Viceroyalty of Peru, but in 1776 it was included with regions of modem  Uruguay, Paraguay, and Bolivia in the Viceroyalty of the Rio de la Plata,  whose capital was Buenos Aires. With the establishment of the United  Provinces of the Rio de la Plata in 1816, Argentina achieved its indepen�  dence from Spain, but its boundaries were not set until the early 20th cen�  tury. In 1943 the government was overthrown by the military; Col. Juan  Peron took control in 1946. He in turn was overthrown in 1955. He  returned in 1973 after two decades of turmoil.

The government of Raul Alfonsin worked to end the  human rights abuses that had characterized the former regimes. Hyperin�  flation, however, led to public riots and Alfonsin�s party�s electoral defeat  in 1989; his Peronist successor, Carlos Menem, instituted laissez-faire eco�  nomic policies.

Argon provides an inert  gas shield in welding and brazing, in lightbulbs and lasers, in Geiger  counters, and in the production and fabrication of certain metals. Because  a radioactive form of argon is produced by decay of a naturally occurring  radioactive potassium isotope, it can be used to date rocks and samples more  than 100,000 years old.</p><p>argon-argon dating See potassium-argon dating</p><p>Argonauts In Greek legend, a band of 50 heroes who went with Jason  in the ship Argo to retrieve the  Golden Fleece from the grove of  Ares at Colchis.

According to one version, the universe as a whole  is like a machine; machines have intelligent designers; like effects have  like causes; therefore, the universe as a whole has an intelligent designer,  which is God. The argument was propounded by medieval Christian  thinkers, especially St. Thomas Aquinas, and was developed in great detail  in the 17th and 18th centuries by writers such as Samuel Clarke (1675�  1729) and William Paley. It was powerfully criticized by David Hume in his  Dialogues Concerning Natural Religion. Immanuel Kant also rejected the</p><p>argument.

Theravada Buddhism regards becoming an arhat as the goal  of spiritual progress. It holds that a seeker must pass through three ear�  lier stages before being reborn in a heaven as an arhat. Mahayana Bud�  dhism criticizes the goal of becoming an arhat as selfish and considers the  bodhisattva to be a higher goal because the bodhisattva remains in the  cycle of rebirths to work for the good of others. This divergence of opin�  ion is one of the fundamental differences between Theravada and Maha�  yana Buddhism.</p><p>Arhus or Aarhus Vor-.husX Seaport (pop., 2001: 286,688), eastern Jut�  land, Denmark. It lies along Arhus Bay and has an extensive harbour. Its  origins are unknown, but it became a bishopric in ad 948 and, with its  many religious institutions, prospered during the Middle Ages. In mod�  ern times, industrialization and harbour expansion have made it Den�  mark�s second largest city.</p><p>aria Solo song with instrumental accompaniment in opera, cantata, or  oratorio. The strophic or stanzaic aria, in which each new stanza might  represent a melodic variation on the first, appeared in opera in Claudio  Monteverdi�s Orfeo (1607) and was widely used for decades. The stan�  dard aria form c. 1650-1775 was the da capo aria, in which the opening  melody and text are repeated after an intervening melody-text section  (often in a different key, tempo, and metre); the return of the first section  was often virtuosically embellished by the singer. Comic operas never  limited themselves to da capo form. Even in serious opera, from c. 1750  a variety of forms were used; Gioacchino Rossini and others often  expanded the aria into a complete musical scene in which two or more  conflicting emotions were expressed. Richard Wagner�s operas largely  abandoned the aria in favour of a continuous musical texture, but arias  have never ceased to be written.</p><p>Ariadne \,ar-e-'ad-ne\ In Greek mythology, the daughter of Pasiphae and  King Minos of Crete. She fell in love with Theseus, who had promised to  slay the Minotaur confined in Minos�s Labyrinth. She gave Theseus a ball  of thread or glittering jewels that enabled him to mark his path and thus  to escape the Labyrinth after killing the monster. Endings to the legend  vary. In one, Theseus abandons Ariadne and she hangs herself; in others,  he carries her to Naxos, where she either dies or marries the god Dionysus.  See also Phaedra.</p><p>Arianism Christian heresy that declared that Christ is not truly divine  but a created being. According to the Alexandrian presbyter Arius (4th  century), God alone is immutable and self-existent, and the Son is not  God but a creature with a beginning. The Council of Nicaea (ad 325) con�  demned Arius and declared the Son to be �of one substance with the  father.� Arianism had numerous defenders for the next 50 years but even�  tually collapsed when the Christian emperors of Rome Gratian and The�  odosius assumed power. The First Council of Constantinople (381)  approved the Nicene Creed and proscribed Arianism. The heresy contin�  ued among the Germanic tribes through the 7th century, and similar  beliefs are held in the present day by the Jehovah's WiTNESSes and by some  adherents of Unitarianism.</p><p>Arias Sanchez Var-e-as-'san-chas\, Oscar (b.

His 1987 Central American peace plan,  signed by the leaders of El Salvador, Guatemala, Honduras, and Nicara�  gua, included provisions for cease-fires, free elections, and amnesty for  political prisoners. He was awarded the 1987 Nobel Peace Prize.</p><p>Aries (Latin: �Ram�) In astronomy, the constellation lying between  Pisces and Taurus; in astrology, the first sign of the zodiac, governing  approximately the period March 21-April 19.

It is often a bright-coloured fleshy envelope, as in  such woody plants as the yews and nutmeg and in members of the arrow-  root family, oxalis, and the castor-oil plant. Animals are attracted to arils  and eat the seeds, dispersing them in their wastes. The aril of nutmeg is  the source of the spice known as mace.</p><p>Arion \3-'ri-3n\ Semilegendary Greek poet and musician. He lived at  Methymna on the island of Lesbos and is identified as the inventor of the  dithyramb. He was sailing homeward after a performing tour when the  sailors decided to kill him and steal his wealth. After singing a dirge for  himself, he jumped overboard, but a dolphin charmed by his music car�  ried him to shore. He reached Corinth before the ship; when the sailors  arrived, the ruler Periander forced them to confess and punished them.  Arion�s lyre and the dolphin were placed in the heavens as the constel�  lations Lyra and Delphinus.</p><p>Ariosto V.ar-e-'o-stoV Ludovico (b. Sept. 8, 1474, Reggio Emilia,  duchy of Modena [Italy]�d. July 6,</p><p>1533, Ferrara) Italian poet. His epic  poem Orlando Furioso (1516) is  regarded as the finest literary expres�  sion of the Italian Renaissance. It  enjoyed immediate popularity  throughout Europe and was highly  influential. He also wrote five com�  edies based on Latin classics but  inspired by contemporary life;  though minor in themselves, they are  among the first of the imitations of  Latin comedy in the vernacular that  would long characterize European  comedy. He also composed seven  satires (1517-25) modeled after  those of Horace .</p><p>Aristagoras \,ar-9-'stag-9-r9s\ (d.</p><p>497) Tyrant of Miletus. He assumed  his regency from his father-in-law,</p><p>Histiaeus (d. 494 bc), who had lost  the trust of the Persian emperor, Dar�  ius I. Possibly incited by Histiaeus,  and with support from Athens and  Eretria, Aristagoras raised the Ionian  revolt against Persia. Defeated, he left Miletus to found a colony in  Thrace, where he was killed by Thracians.</p><p>Aristarchus \,ar-3-'star-k3s\ of Samos (b. c. 310 bc �d. c. 230 bc)  Greek astronomer. His advanced ideas on the movement of the Earth  (which he asserted revolved around the Sun) are known from Archimedes  and Plutarch. His only surviving work is the short treatise �On the Sizes  and Distances of the Sun and Moon�; though the values he obtained are  inaccurate, he showed that the Sun and stars are at immense distances. A  peak in the centre of a lunar crater named for him is the brightest forma�  tion on the Moon.</p><p>Aristide \,ar-i-'sted\, Jean-Bertrand (b. July 15, 1953, Port Salut,  Haiti) First president of Haiti (1991, 1994-96, 2001-04) to be elected in  free democratic elections. A priest in the Roman Catholic Salesian order,  he aligned himself with the poor and opposed the harsh regime of Jean-  Claude Duvalier, son of Francois Duvalier, often putting himself at odds  with the church hierarchy and the military. Expelled by the Salesians in  1988, he formally requested that he be relieved of his priestly duties in  1994. In 1990 progressive-centre forces united behind Aristide and swept  him into power. He initiated dramatic reforms but was ousted in a mili�  tary coup after only seven months in office. Though restored to office in  1994 with the help of U.S. occupying troops, he received little aid with  which to address his country�s endemic ills. Constitutionally prohibited  from seeking a consecutive term, he stepped down in 1996 but remained  Haiti�s most potent political figure. In 2000 he was reelected president</p><p>amid charges of electoral fraud. A coup against Aristide failed in 2001,  but unrest with his rule increased until a full-scale rebellion in 2004 forced  him to flee the country.</p><p>Aristides \,ar-3-'stI-dez\ (2nd century ad) Athenian philosopher, one of  the earliest Christian Apologists. His Apology for the Christian Faith dis�  cussed the harmony in creation and the nature of the divine being and  stated that barbarians, Greeks, and Jews were all inadequate in their con�  ception of the deity and their religious practices. Long considered lost,  the Apology was reconstructed in the late 19th century.</p><p>Aristides the Just (fl. 5th century bc) Athenian statesman and general.  He was ostracized in 482 bc, probably for opposing Themistocles but was  recalled in 480 and helped defeat the Persians at the battles of Salamis and  Plataea. In 478 he helped Sparta�s eastern allies form the Delian League;  allied with Athens and based on Athenian naval power and the trust Aris�  tides inspired, the league effectively became the Athenian empire.</p><p>aristocracy \,ar-3-'sta-kr9-se\ Originally, leadership by a small privi�  leged class or a minority thought to be best qualified to lead. Plato and  Aristotle considered aristocrats to be those who are morally and intellec�  tually superior, and therefore fit to govern in the interests of the people.  The term has come to mean the upper layer of a stratified group. Most  aristocracies have been hereditary, and many European societies stratified  their aristocratic classes by formally titling their members, thereby mak�  ing the term roughly synonymous with nobility. See also oligarchy.</p><p>Aristophanes \ l ar-o- , sta-f3- l nez\ (b. c. 450� d. c. 388 bc) Greek play�  wright. An Athenian, he began his career as a comic dramatist in 427. He  wrote approximately 40 plays, of which 11 survive, including The Clouds  (423), The Wasps (422), The Birds (414), Lysistrata (411), and The Frogs  (405). Most of the plays typify the Old Comedy (of which they are the  only extant representatives), in which mime, chorus, and burlesque were  important features. His satire, wit, and merciless topical commentary  made him the greatest comic dramatist of ancient Greece.</p><p>Aristotle (b. 384, Stagira�d. 322 bc, Chalcis) Greek philosopher and  scientist whose thought determined the course of Western intellectual his�  tory for two millenia. He was the son of the court physician to Amyntas  III, grandfather of Alexander the Great. In 367 he became a student at the  Academy of Plato in Athens; he remained there for 20 years. After Pla�  to�s death in 348/347, he returned to Macedonia, where he became tutor  to the young Alexander. In 335 he founded his own school in Athens, the  Lyceum. His intellectual range was vast, covering most of the sciences  and many of the arts. He worked in physics, chemistry, biology, zoology,  and botany; in psychology, political theory, and ethics; in logic and meta�  physics; and in history, literary theory, and rhetoric. He invented the study  of formal logic, devising for it a finished system, known as syllogistic, that  was considered the sum of the discipline until the 19th century; his work  in zoology, both observational and theoretical, also was not surpassed  until the 19th century. His ethical and political theory, especially his con�  ception of the ethical virtues and of human flourishing (�happiness�),  continue to exert great influence in philosophical debate. He wrote pro-  lifically; his major surviving works include the Organon, De Anima (�On  the Soul�), Physics, Metaphysics, Nicomachean Ethics, Eudemian Ethics,  Magna Moralia, Politics, Rhetoric, and Poetics, as well as other works  on natural history and science. See also teleology.</p><p>arithmetic Branch of mathematics that deals with the properties of  numbers and ways of combining them through addition, subtraction, mul�  tiplication, and division. Initially it dealt only with the counting numbers,  but its definition has broadened to include all real numbers. The most  important arithmetic properties (where a and b are real numbers) are the  commutative laws of addition and multiplication, a + b = b + a and ab =  ba; the associative laws of addition and multiplication, a + (b + c) = (a +  b) + c and a{bc) = {ab)c\ and the distributive law, which connects addition  and multiplication, a(b + c) = ab + ac. These properties include subtrac�  tion (addition of a negative number) and division (multiplication by a  FRACTION).</p><p>Arius \'ar-e-os\ (b. c. 250, Libya�d. 336, Constantinople, Byzantine  Empire) Christian priest and heretic whose teachings gave rise to the doc�  trine of Arianism. He was leader of a Christian community near Alexan�  dria, Egypt, where he preached doctrines that combined Neoplatonism with  a literal, rationalist interpretation of biblical texts. By asserting the abso�  lute oneness and immutability of God, he called into question the divin�  ity of Christ. His views were publicized through his major work, Thalia</p><p>Ariosto, woodcut after a drawing by  Titian from the third edition of Orlando  furioso , 1532.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Arizona &#x25BA; Arlington I 103</p><p>(c. 323). In 325 the Council of Nicaea declared him a heretic. He was  striving to compromise his views and win readmission to the church when  he died suddenly in Constantinople. The Arian heresy posed a threat to  Christian orthodoxy for several centuries.</p><p>Arizona State (pop., 2000: 5,130,632), southwestern U.S. Bordered by  Mexico and the U.S. states of Utah, New Mexico, California, and Nevada,  it covers 113,999 sq mi (295,256 sq km). Its capital is Phoenix. Its high�  est point is Humphreys Peak, at 12,633 ft (3,850 m). The site of Grand  Canyon and Petrified Forest national parks, Arizona also contains much of  America�s Indian tribal lands. Humans settled the area more than 25,000  years ago. Nomadic Apache and Navajo Indians arrived after the collapse  of the Anasazi and Hohokam civilizations. They were followed in the 16th  century by Spanish treasure seekers from Mexico, including Francisco  Vazquez de Coronado, establishing Mexico�s claim to the area. In 1776  the Mexican army built a presidio at Tucson. After the Mexican War, Ari�  zona was ceded to the U.S. as part of New Mexico in 1848; the Gadsden  Purchase added to it in 1853. Organized as a territory in 1863, Arizona  became the 48th state in 1912. Though still lightly populated, it has grown  rapidly in population in recent decades, largely because of its climate.  About one-fifth of the population is Spanish-speaking, while about 5% is  American Indian, including Navajo, Hopi, Apache, Papago, and Pima. Its  diverse economy includes agriculture, mining, aerospace, electronics, and  tourism.</p><p>Arjan Vor-j9n\ (b. 1581�d. 1606) Fifth Guru of the Sikhs (1581-1606)  and jts first martyr. He compiled the volume of Sikh scripture on which  the Adi Granth is based, and he completed the Golden Temple at Amritsar,  India. The first Guru to serve as both temporal and spiritual head of  Sikhism, he built up Amritsar as a commercial centre and enlarged mis�  sionary efforts. He was also a prolific poet and writer of hymns. He pros�  pered under the tolerant Mughal emperor Akbar but was tortured to death  by Akbar�s successor for not altering the Adi Granth to remove passages  that gave offense to Hinduism or Islam.</p><p>Arjuna \'3r-ju-n9\ One of the five brothers who are the heroes of the  Mahabharata. His reluctance to go into battle prompts Krishna, manifested  as his friend and charioteer, to deliver the discourse on duty that consti�  tutes the Bhagavadgita. An exemplar of skill, duty, and compassion as well  as a seeker of true knowledge, Arjuna is a central figure in Hindu myth  and theology.</p><p>Ark of the Covenant In Judaism and Christianity, the ornate, gold-  plated wooden chest that in biblical times housed the two tablets of the  Law given to Moses by God. The Levites carried the Ark during the  Hebrews� wandering in the wilderness. Following the conquest of  Canaan, it was kept at Shiloh but was sometimes carried into battle by  the Israelites. David took it to Jerusalem, and Solomon placed it in the  Temple of Jerusalem, where it rested in the Holy of Holies and was seen  only by the high priest on Yom Kippur. It is believed to have been captured  when Jerusalem fell to the Babylonians in 586 bc, and its subsequent fate  is unknown.</p><p>Arkansas State (pop., 2000: 2,673,400), south-central U.S. Bordered  by Missouri, Tennessee, Mississippi, Louisiana, Texas, and Oklahoma, it  covers 53,178 sq mi (137,730 sq km). Its capital is Little Rock, and its  highest point is Mount Magazine, at 2,753 ft (839 m). The earliest inhab�  itants were Indian bluff dwellers along the Mississippi River c. ad 500.  Mound-building cultures later left burial mounds along the river. Spanish  and French explorers traversed the region in the 16th- 17th centuries; the  first permanent European settlement was founded at Arkansas Post in  1686. Acquired by the U.S. as part of the Louisiana Purchase, Arkansas  Territory was established in 1819; the state�s current boundaries were  fixed in 1828. Arkansas became the 25th state in 1836. It seceded in 1861  to join the Confederacy in the American Civil War; it was readmitted to  the Union in 1868. Following Reconstruction, a rigid policy of segrega�  tion lasted until 1957, when court-ordered desegregation of the schools  was implemented. Once dominated by agriculture, the state�s economy  now also includes mining and manufacturing. Tourism is promoted, espe�  cially by the mineral springs at Hot Springs National Park and resorts in  the Ozark Mountains.</p><p>Arkansas River River, rising in central Colorado, U.S. At 1,450 mi  (2,333 km) long, it flows east through southern Kansas and southeast  across northeastern Oklahoma and bisects Arkansas, where it empties into  the Mississippi River. Navigable for 650 mi (1,046 km), its largest tributar�  ies are the Canadian and Cimarron rivers. It is believed to have been</p><p>crossed by Francisco Vazquez de Coronado in 1541 near the site of Dodge  City, Kan., and by Zebulon Pike in 1806.</p><p>Arkhangelsk \,3r-'kan-gilsk\ or Archangel City (pop., 2002:  355,500), northwestern Russia. Located near the mouth of Northern Dvina  River, it has a large harbour kept open in winter by icebreakers. The area  was settled by Norsemen in the 10th century ad. In 1553 it was visited  by the English who were looking for the Northeast Passage. Founded in  1584 as a monastery of Michael the archangel, it became a trading station  of the Muscovy Co. It was opened to European trade by Tsar Boris  Godunov and flourished as the sole Russian seaport until St. Petersburg  was built in 1703. Arkhangelsk was the scene of British, French, and U.S.  support of the northern Russian government against the Bolsheviks in  1918-20. During World War II it received convoys of lend-lease goods  from Britain and the U.S. (1941-45). It is a major timber-exporting port  and has extensive shipbuilding facilities.</p><p>Arkona W. Slavic citadel-temple of the war-god Svantovit, built in the  9th-10th century ad and destroyed in 1168/69 by Christian Danes when  they stormed the island of Riigen in the southwestern Baltic. According to  Saxo Grammaticus, it was a log structure with red roof, surrounded by a  yard and fence, carved and painted with symbols. The inner sanctum con�  tained a statue of Svantovit with four heads and throats facing in opposite  directions. Excavations in 1921 proved the temple�s actual existence.</p><p>arkose Yar-,kos, 'ar-,koz\ Coarse sandstone that has formed by the dis�  integration of granite without appreciable decomposition. It thus consists  primarily of quartz and feldspar grains. In the absence of stratification,  arkose may bear superficial resemblance to granite, and it sometimes has  been described as reconstituted granite, or granite wash. Like the granite  from which it was formed, arkose is pink or gray.</p><p>Arkwright, Sir Richard (b. Dec. 23, 1732, Preston, Lancashire,  Eng.�d. Aug. 3, 1792, Cromford, Derbyshire) British textile industrialist  and inventor. His first spinning machine was patented in 1769 (see Lewis  Paul). His water frame (so-called because it operated by waterpower) pro�  duced a cotton yarn suitable for warp (see weaving), stronger than thread  made on the spinning jenny, which proved suitable only for weft. He intro�  duced all-cotton calico in 1773. He opened several factories equipped with  machinery for carrying out the phases of textile manufacturing from card�  ing through spinning (see drawing).</p><p>Arledge, Roone (b. July 8, 1931, Forest Hills, N.Y., U.S.�d. Dec. 5,  2002, New York City) U.S. television executive. He began work at  ABC-TV in 1960 as a sports producer. He later became president of ABC  Sports and group president of ABC News and Sports (1985-90). He cre�  ated sports programs such as Wide World of Sports (from 1961) and Mon�  day Night Football (from 1968) and produced television coverage of 10  Olympic games, making many technical and editorial innovations in  sports coverage. As president of ABC News he developed several suc�  cessful news shows such as Nightline (from 1980) and PrimeTime Live  (from 1989).</p><p>Arlen, Harold orig. Hyman Arluck (b. Feb. 15, 1905, Buffalo,  N.Y., U.S.�d. April 23, 1986, New York, N.Y.) U.S. songwriter. After  working as a performer and arranger, in 1929 he began a collaboration  with lyricist Ted Koehler (1894-1973) with the song �Get Happy�; until  the mid-1930s they wrote many songs that were featured in shows at Har�  lem�s Cotton Club. Arlen� s scores for Broadway musicals include  Bloomer Girl (1944) and St. Louis Woman (1946). For Hollywood films  Arlen wrote the songs �It�s Only a Paper Moon,� �Let�s Fall in Love,�  and �That Old Black Magic.� His most famous song is perhaps �Over the  Rainbow� (lyrics by E.Y. Harburg) from The Wizard of Oz (1939).</p><p>Arles Varl, 'arlz\ City (pop., 1999: 50,453), southeastern France. Occu�  pied and built up by the Romans in the 1st century bc, Arles became,  through commerce, a leading city of the Roman Empire. In the 10th cen�  tury ad it became the capital of Burgundy, known also as the kingdom of  Arles. Portions of the Roman wall around the old town remain, and a  Roman arena of the 1st century bc is still used for bullfights and plays.  The city was home to Vincent van Gogh during one of his most produc�  tive periods. Arles is still a river port, but its economy is based largely  on tourism and agriculture.</p><p>Arlington Unincorporated settlement (pop., 2000: 189,453), northern  Virginia, U.S. Lying across the Potomac River from Washington, D.C., it  is the capital of Arlington county, which was part of Washington, D.C.,  from 1801 to 1847, when it was returned to Virginia.

The term may also denote the limb or the locomotive or pre�  hensile organ of an invertebrate (e.g., the ray of a starfish or the tentacle  of an octopus).</p><p>Armada, Spanish Great fleet sent by Philip II of Spain in 1588 to  invade England in conjunction with a Spanish army from Flanders. Philip  was motivated by a desire to restore the Roman Catholic faith in England  and by English piracies against Spanish trade and possessions. The  Armada, commanded by the duke of Medina-Sidonia, consisted of about  130 ships. In the weeklong battle, the Spanish suffered defeat after the  English launched fire ships into the Spanish fleet, breaking the ships� for�  mation and making them susceptible to the English ships� heavy guns.  Many Spanish ships were also lost during the long voyage home, and a  total of perhaps 15,000 Spaniards died. The defeat of the Armada, in  which Francis Drake played a principal role, saved England and the Neth�  erlands from possible absorption into the Spanish empire.</p><p>armadillo Any of 20 species of armoured mammals (family Dasypo-  didae) related to sloths and anteaters.</p><p>Armadillos are stout and short�  legged, with strong, curved claws  and a protective covering of pinkish  to brown armour composed of bony  plates covered with tough scales.</p><p>The plates are separated by flexible  bands of tissue. One species lives in  the U.S., the others in tropical and  subtropical regions to the south, pri�  marily in South America. Most  inhabit open areas, but some can be  found in forests. Species range in  size from about 6 in. (16 cm) to 5 ft  (1.5 m) long. They live alone, in pairs, or in small groups and feed on  termites or other insects, vegetation, small animals, and carrion.</p><p>Armageddon \,ar-m9-'ged-3n\ In the New Testament, the place where  the kings of the earth under demonic leadership will wage war on the  forces of God at the end of history. Armageddon is mentioned only in the  Revelation to John. The name may mean �Mountain of Megiddo,� a ref�  erence to the city of Megiddo, which held strategic importance in Pales�  tine. Other biblical references suggest Jerusalem as the battle site.</p><p>Armagh \'ar-,ma\ District (pop., 2001: 54,263), Northern Ireland. For�  merly part of County Armagh, the district was established in 1973. It lies  south of Lough Neagh. The northern part of the district is the island�s  main fruit-growing region; the southern part, along the Irish border, was  a hotbed of sectarian violence through the late 20th century. The district  seat is Armagh town. According to tradition, St. Patrick established his  principal Irish church here in the 5th century. The area was the leading  intellectual centre of the Western world in the 5th-9th centuries. Taken  by English Protestant forces in the 16th century, Armagh became a pros�  perous centre for Protestant clergy and gentry, a circumstance reflected in  its many Georgian monuments and buildings.</p><p>Armagnac \,ar-ma-'nyak\ Small territory in historical Gascony, south�  western France. A portion was part of the Roman province of Aquitania  (see Aquitaine). From c. 960 it was the separate countship of Armagnac,  and it grew to occupy a buffer zone between lands controlled by the  French kings (Toulouse) and those controlled by the English (Guyenne).  It led the resistance to the English king Henry V�s invasion of France but  suffered a setback at the Battle of Agincourt. It was first annexed to France  in 1497, became a countship again, but finally, by descent through the  rulers of Navarra, returned to the French crown in 1607. Again a count-  ship from 1645, it was dissolved in 1789. The region produces the famous  Armagnac brandy.</p><p>Armani \ar-'ma-ne\, Giorgio (b.

In  1974-75 he introduced his own label of ready-to-wear apparel for men  and women. In 1980-81 he founded Giorgio Armani USA, Emporio  Armani, and Armani Jeans, and in 1989 he opened shops in London. He  was a leader in the move toward a pared-down, unstructured silhouette  in menswear and was responsible for the wide-shouldered look for execu�  tive women. His designs, often characterized by understated glamour and  luxurious fabrics, introduced ease and streamlined modernity into late  20th-century dressing.</p><p>Armed Islamic Group French Groupe Islamique Armee  (GIA) Algerian militant group. It was formed in 1992 after the govern�  ment nullified the likely victory of the Islamic Salvation Front in 1991 leg�  islative elections and was fueled by the repatriation of numerous Algerian  Islamists who had fought in the Afghan War (1978-92). The GIA began  a series of violent, armed attacks against the government and against for�  eigners in Algeria and has been accused of civilian massacres�although  it has been alleged that many such atrocities were committed by security-  service infiltrators and special military units. It has also engaged in attacks  abroad (particularly in France) and purportedly maintained links with  militant Islamic groups throughout the world. Estimates of GIA strength  have varied from hundreds to several thousand guerrillas.</p><p>Armenia officially Republic of Armenia Country, Transcaucasia,  western Asia.

Armenians constitute nine-tenths of the popu-</p><p>dominantly Armenian Apostolic; also  Roman Catholic); also Islam. Currency: dram. Armenia is a mountainous  country with an average elevation of 5,900 ft (1,800 m). The Lesser Cau�  casus ranges stretch across its northern portion, and Lake Sevan lies in  the east-central part. Armenia has a dry and continental climate that  changes dramatically with elevation. Though the country has become  highly industrialized (as a result of the development of hydroelectric  power during Soviet rule) and increasingly urbanized, agriculture is still  important. The Republic of Armenia is a successor state to a historical  region in Caucasia. Historical Armenia�s boundaries have varied consid�  erably, but old Armenia extended over what are now northeastern Turkey  and the Republic of Armenia. The area was equivalent to the ancient  kingdom of Urartu, which ruled c. 1270-850 bc. It was later conquered  by the Medes (see Media) and Macedonia and still later allied with Rome.  Armenia adopted Christianity as its national religion c. ad 300.

Over the next  centuries, as parts were ceded to other rulers, nationalism arose among  the scattered Armenians; by the late 19th century it had caused widespread  disruption. Fighting between Ottomans and Russians escalated when part  of Armenia was ceded to Russia in 1828, and it continued through World  War 1 (1914-18), leading to genocide against Armenians (see Armenian  massacres). With the Ottoman defeat, the Russian portion became part of  a Soviet republic in 1922. Armenia was established as a constituent repub�  lic of the U.S.S.R. in 1936. The U.S.S.R. began to dissolve in the late  1980s, and Armenia declared its independence in 1991. In the years that  followed, it fought Azerbaijan for control of Nagorno-Karabakh, a con�  flict that continued despite attempts to settle it. Large numbers of Arme�  nians left the country in the 1990s following an economic downturn, and  many stayed away even after the economy began to improve.</p><p>Armenia, Little See Little Armenia</p><p>Armenian Armenian Hay plural Hayk or Hayq Member of an  Indo-European people first recognized in the early 7th century bc when  they moved into areas of Transcaucasia, Anatolia, and the Middle East  that came to be known as Armenia. Armenian history has been one of  nearly constant struggles for independence from foreign domination, first  from the Medes and Persians, the Seleucid dynasty, and the Roman Republic  and Empire and later from the Byzantine Empire, the SeuGq dynasty, the Otto�  man Empire, the Safavid dynasty, and tsarist Russia. At the beginning of  the 20th century most Armenians were driven from Anatolia or killed by  Ottoman forces during the Armenian massacres. The Republic of Armenia  was declared in 1990 after being part of the Soviet Union since 1922.  More than 3.5 million Armenians live there, and there is an appreciable  diaspora in other countries of Transcaucasia, in parts of the Middle East,  and in the West. Armenian culture reached an apex in the 14th century,  producing highly regarded sculpture, architecture, and fine art. Until the  20th century, Armenians were primarily agricultural; now they are highly  urbanized. Traditionally they are either Orthodox or Roman Catholic  Christians; Armenia was considered the first Christian state.</p><p>Armenian language Indo-European language of the Armenians. It is  spoken by perhaps five to six million people worldwide. Armenian has  undergone phonetic and grammatical changes that make it completely dis�  tinct from other branches of Indo-European; its closest affinity may be with  Greek, though this hypothesis has been vigorously disputed. Its long his�  tory of contact with Iranian languages has resulted in the adoption of many  Persian loanwords. According to tradition, the unique Armenian alphabet  was created by the cleric Mesrop Mashtots in ad 406 or 407. Armenian of  the 5th-9th centuries (Grabar, or Classical Armenian) was employed as the  literary language into modern times. A 19th-century cultural revival led to  the formation of two new literary languages: West Armenian, based on the  speech of Istanbul Armenians, and East Armenian, based on the speech of  Transcaucasian Armenians. Because of a long tradition of emigration and  the massacres and expulsions during the last decades of Ottoman rule, most  speakers of West Armenian live outside Anatolia. East Armenian is the lan�  guage of the present-day Republic of Armenia.</p><p>Armenian massacres Murder and expulsion of Turkish Armenians  by the Ottoman Empire under Abdulhamid II in 1894-96 and by the Young  Turk government in 1915-16. In 1894, when the Armenians began agitat�  ing for territorial autonomy and protesting against high taxes, Ottoman  troops and Kurdish tribesmen killed thousands. In 1896, hoping to call  attention to their plight, Armenian revolutionaries seized the Ottoman  Bank in Istanbul. Mobs of Muslim Turks, abetted by elements of the gov�  ernment, killed more than 50,000 Armenians in response. Sporadic kill�  ings occurred over the next two decades. In response to Russia�s use of  Armenian troops against the Ottomans in World War I (1914-18), the  government deported 1.75 million Armenians south to Syria and Meso�  potamia, in the course of which some 600,000 Armenians were killed or  died of starvation.</p><p>Armenian Secret Army to Liberate Armenia See ASALA</p><p>Armistice (Nov. 11, 1918) Agreement between Germany and the Allies  ending World War I. Allied representatives met with a German delega�  tion in a railway carriage at Rethondes, France, to discuss terms. The  agreement was signed on Nov. 11, 1918, and the war ended at 11:00 am  that day (�the 11th hour of the 11th day of the 11th month�). The prin�  cipal term was that Germany would evacuate Belgium, France, and  Alsace-Lorraine. Negotiations formalizing the armistice were conducted</p><p>at the Paris Peace Conference. Later a �stab in the back� legend developed  in Germany, asserting that the German military situation had not been  hopeless and that traitorous politicians had done the Allies� bidding by  signing the Armistice.</p><p>Armory Show formally International Exhibition of Modern</p><p>Art Exhibition of painting and sculpture held in 1913 at the 69th Regi�  ment Armory in New York City. Conceived by its organizers, the Asso�  ciation of American Painters and Sculptors, as a selection of works  exclusively by U.S. artists, it evolved into a comprehensive look at cur�  rent European art movements, due in part to the advanced vision of asso�  ciation president Arthur B. Davies. Of the 1,300 works assembled, one-  third were European, tracing the evolution of modern art from Francisco  de Goya to Marcel Duchamp and Vasily Kandinsky, with works representa�  tive of Impressionism, Symbolism, Post-Impressionism, Fauvism, and Cubism.  Perhaps the most controversial work was Duchamp�s nearly abstract Nude  Descending a Staircase, No. 2 (1912). The U.S. artists featured were  mainly members of the Ash Can school and The Eight. The show exposed  the American public for the first time to advanced European art; Ameri�  can art suffered by contrast. The exhibition traveled to Chicago and Bos�  ton, establishing itself as a decisive event in the development of U.S. art  and art collecting.</p><p>armour or body armour Protective clothing that can shield the  wearer from weapons and projectiles. By extension, armour is also pro�  tective covering for animals, vehicles, and so on. Prehistoric warriors used  leather hides and helmets. Chinese warriors used rhinoceros skin in the  11th century bc, and Greek infantry wore thick, multilayered metal-and-  linen cuirasses (armour covering the body from neck to waist) in the 5th  century bc. Shirts of chain mail were worn throughout the Roman Empire,  and mail was the chief armour of western Europe until the 14th century.  Ancient Greeks and Romans used armour made of rigid metal plates,  which reappeared in Europe around the 13th century. Plate armour domi�  nated European design until the 17th century, when firearms began to  make it obsolete. It began to disappear in the 18th century, but the hel�  met reappeared in World War I and became standard equipment. Modern  body armour (the bulletproof vest) covers the chest and sometimes the  groin; it is a flexible garment reinforced with steel plates, fibreglass, boron  carbide, or multiple layers of synthetic fabric such as Kevlar.</p><p>helmet</p><p>MERRIAM-WEBSTER INC.</p><p>Armour, Philip Danforth (b.

When railcar refrigeration was introduced in the 1880s (see  Gustavus Franklin Swift), he established distributing plants in eastern states  and began exporting Armour meat products to Europe. His Armour &amp; Co.  enterprises helped make Chicago the meatpacking capital of the world.</p><p>armoured vehicle Motor vehicle with plating for protection against  bullets, shells, or other projectiles that moves on wheels or tracks. The  tank is the chief armoured vehicle for larger military forces. Other mili�  tary types include infantry fighting vehicles, amphibious landing vehicles,  and mobile weapons platforms such as self-propelled artillery and anti�  aircraft guns. Infantry fighting vehicles, descended from the armoured  personnel carriers of World War II and the Vietnam War, are armoured,  tracked vehicles that transport infantry into battle but also serve as plat�  forms from which soldiers can fight without dismounting. Armoured cars  are wheeled civilian vehicles, ranging from commercial trucks to luxury  sedans, that generally are equipped with armour and other amenities for  securely transporting valuables and individuals over paved roads.</p><p>armoury practice Production system for the assembly of finished  products, in this case arms. With the adoption of the Model 1842 mus�  ket, the U.S. military achieved the large-scale assembly of weapons from  uniform, interchangeable parts. By the mid-1850s arms makers around the  world were beginning to copy this American System of manufacture, which  contributed to the creation of the modern military small arm, especially  after the introduction of percussion ignition and rifled barrels.</p><p>arms control Limitation of the development, testing, production,  deployment, proliferation, or use of weapons through international agree�  ments. Arms control did not arise in international diplomacy until the first  Hague Convention (1899). The Washington Conference (1921-22) and the  Kellogg-Briand Pact (1928) were broken without much fear of sanction.  U.S.-Soviet treaties to control nuclear weapons during the Cold War were  taken more seriously. In 1968 the two superpowers and Britain sponsored  the Nuclear Non-proliferation Treaty (signed also by 59 other countries),  which committed signatory countries not to promote the spread, or pro�  liferation, of nuclear weapons to countries that did not already possess  them.

Jan. 31/Feb. 1, 1954, New York City) U.S. inventor. He studied  at Columbia University, where he devised a feedback circuit that brought  in signals with a thousandfold amplification (1912). At its highest ampli�  fication, the circuit shifted from being a receiver to being a primary gen�  erator of radio waves, and as such it is at the heart of all radio and  television broadcasting. It earned him the Franklin Medal, the highest U.S.  scientific honour. His 1933 invention of circuits that produced the carrier  waves for frequency modulation (FM) made high-fidelity broadcasting  possible.</p><p>Armstrong, Gillian (b. Dec. 18, 1950, Melbourne, Austl.) Australian  film director. She first garnered international acclaim as the director of  My Brilliant Career (1979), a feminist film about a young woman aspir�  ing to be a writer in Victorian-era Australia. Her subsequent works include  Australian films such as The Last Days of Chez Nous (1993) and Oscar  and Lucinda (1997), as well as U.S. films such as Mrs. Soffel (1984), Little  Women (1994), and Charlotte Gray (2001).</p><p>Armstrong, Lance (b. Sept. 18, 1971, Plano, Texas, U.S.) American  cyclist and the first rider to win seven Tour de France titles (1999-2005).  Armstrong began his professional cycling career in 1992 when he joined  the Motorola team. He won stages of the Tour de France in 1993 and  1995 but withdrew from three of four Tours he attempted from 1993 to  1996. After the 1996 Tour, Armstrong fell ill, suffering from testicular  cancer that had spread to his lungs and brain. Months of treatments fol�  lowed before he could attempt his comeback. In 1998 he won the Tour  of Luxembourg, and on July 25, 1999, he became the second American  to win the Tour de France and the first to win it for an American team  (three-time winner Greg LeMond had raced with European teams). In  2003 Armstrong won his fifth consecutive Tour de France, tying a record  set by Miguel Indurain, and the following year he broke the record with  his sixth consecutive win. After winning his seventh Tour in 2005, Arm�  strong announced his retirement.</p><p>Armstrong, Louis (b. Aug. 4, 1901, New Orleans, La., U.S.�d. July 6,  1971, New York, N.Y.) U.S. jazz trumpeter and singer. As a youth in New</p><p>Orleans, he participated in marching,  riverboat, and cabaret bands. A child�  hood nickname, Satchelmouth, was  shortened to Satchmo and used  throughout his life. In 1922 he moved  to Chicago to join King Oliver�s Cre�  ole Jazz Band (see Dixieland). In 1924  he joined the Fletcher Henderson  Orchestra in New York City; the fol�  lowing year he switched from cornet  to trumpet and began recording under  his own name with his Hot Five and  Hot Seven ensembles. In these  recordings the prevailing emphasis  on collective improvisation gives way to his developing strength as soloist  and vocalist. By the time of his �West End Blues� (1928), Armstrong had  established the preeminence of the virtuoso soloist in jazz. His vibrant  melodic phrasing, inventive harmonic improvisation, and swinging rhyth�  mic conception established the vernacular of jazz music. His powerful  tone, great range, and dazzling velocity set a new technical standard. He  also was one of the first scat singers, improvising nonsense syllables in the  manner of a horn. He became something more than a jazz musician: solo  attraction, bandleader, film actor, and international star.</p><p>Arndt, Ernst Moritz (b. Dec. 26, 1769, Schoritz bei Gartz, Swed.�d.  Jan. 29, 1860, Bonn, Ger.) Swedish-born German prose writer, poet, and  patriot. He rejected the Lutheran ministry at age 28 and eventually became  a professor of history at Greifswald and Bonn. Among his important  works is the huge Spirit of the Times, 4 vol. (1806-18), a bold call for  political reforms that expressed German national awakening during the  Napoleonic era. Not all of Arndt�s poems were inspired by political ideas;  Gedichte (1804-18) contains many religious poems of great beauty.</p><p>Arne, Thomas Augustine (b. March 12, 1710, London, Eng.�d.  March 5, 1778, London) British composer. Son of a London upholsterer,  he secretly taught himself instrumental skills and composition with the  help of an opera musician. Smitten by the opera, he had an early success  with his own first opera, Rosamond (1733), and thereafter concentrated  almost exclusively on the theatre. As composer to Drury Lane Theatre  and London�s great pleasure gardens, he became Britain�s leading theat�  rical composer and, after George Frideric Handel, possibly the finest Brit�  ish composer of the century. Of his approximately 90 theatrical works,  the best known are Comus (1738), The Judgment of Paris (1740), and  Artaxerxes (1762). His song �Rule, Britannia� became an unofficial  national anthem.

In 1955 he became a  civilian research pilot for the fore�  runner of NASA. He joined the  space program in 1962 with the sec�  ond group of astronauts. In 1966, as  command pilot of Gemini 8, he and  David Scott completed the first  manual space docking maneuver,  with an unmanned Agena rocket.

The term may be applied to a  large unit organized for independent action or to a nation�s or ruler�s over�  all military organization for land warfare. The character and organization  of armies have varied through history. At various times armies have been  built around infantry soldiers or mounted warriors (e.g., cavalry) or men in  machines, and have been made up of professionals or amateurs, of merce�  naries fighting for pay or for plunder, or of patriots fighting for a cause.

He joined the  American Revolutionary army in  1775 and contributed to American  victories at the Battle of Ticon-  deroga, at Fort Stanwix, N.Y., and at  the Battle of Saratoga, where he was  seriously wounded. He was made a  major general and placed in com�  mand of Philadelphia, where he lived  extravagantly and socialized with  wealthy loyalist sympathizers, one of  whom he married in 1779. Repri�  manded for fiscal irregularities in his  command, he began secret overtures  to the British. After receiving com�  mand of the fort at West Point, N.Y.</p><p>(1780), he offered to surrender it to  the British for �20,000.

After  World War I, with Billy Mitchell he became an eloquent advocate of an  expanded air force. He rose through the ranks of the U.S. Army Air Corps  to become its commander in 1938, and he commanded the Army Air  Forces worldwide during World War II, overseeing a massive buildup and  greatly influencing air bombardment strategy. He was named general of  the army in 1944 and, after the National Defense Act of 1947 created an  independent Air Force, general of the Air Force.</p><p>Arnold, Matthew (b.

His verse includes �Dover  Beach,� his most celebrated work; �Sohrab and Rustum,� a romantic epic;  and �The Scholar Gipsy� and �Thyrsis.� Culture and Anarchy (1869), his  central work of criticism, is a masterpiece of ridicule as well as a search�</p><p>ing analysis of Victorian society. In a later essay, �The Study of Poetry,�  he argued that, in an age of crumbling creeds, poetry would replace reli�  gion and that therefore readers would have to understand how to distin�  guish the best poetry from the inferior.</p><p>Arnold, Thomas known as Doctor Arnold (b.

He studied  under Nicola Pisano and assisted him on the pulpit for Siena Cathedral  (1265-68). In 1277 he went to Rome, where he worked for Charles of  Anjou, king of Sicily. He also designed and constructed monuments,  including the tomb of Cardinal de Braye in San Domenico, Orvieto. In  1296 Arnolfo returned to Florence to undertake his most important com�  mission, the design of the Duomo (the cathedral of Florence) and the  carving of statues for its facade. Other buildings in Florence attributed to  him include the Palazzo Vecchio and the church of Santa Croce. The  structural and decorative elements of Santa Croce and the Duomo have a  unity, balance, and a lightness of movement that demonstrate Arnolfo�s  complete mastery of the late 13th-century Gothic architectural vocabu�  lary. His works embody the transition between the late Gothic and Renais�  sance architectural sensibilities.</p><p>Arnulf (d. Dec. 8, 899) King of Germany. Originally duke of Carinthia,  he was elected king of the eastern Franks in 887, deposing his uncle,  Charles the Fat. The western Franks, Burgundy, and Italy refused to rec�  ognize Arnulf, thus dividing the Carolingian empire. He defeated the  Vikings (891), ending their raids up the Rhine River, and maintained con�  trol of Lotharingia (now Lorraine). He invaded Italy at the urging of Pope  Formosus, captured Rome (895), and was crowned emperor in 896. Ill�  ness forced him to return to Germany, however, and the previous emperor  continued to rule. Arnulf s last years saw invasions by Magyars and Slavs  and the collapse of his power.</p><p>aromatherapy Therapy using essential oils and water-based colloids  extracted from plant materials to promote physical, emotional, and spiri�  tual health and balance. Single or combined extracts may be diffused into  inhaled air, used in massage oil, or added to bathwater. Inhaled molecules  of these extracts stimulate the olfactory nerve, sending messages to the  brain�s limbic system (the seat of memory, learning, and emotion) that  are said to trigger physiological responses (e.g., eucalyptus relieves con�  gestion, lavender promotes relaxation). Mainstream medical practitioners  question the claim of independent physiological effects; they consider  many of the benefits more likely due to the conditioned responses that  odors can reinforce or help create. The oils and solutions used have been  shown to have certain effects but are not standardized. The few risks  involved include allergic reactions.</p><p>aromatic compound Any of a large class of organic compounds  whose molecular structure includes one or more planar rings of atoms,  usually but not always six carbon atoms.

His early plays, in particular Picnic on the  Battlefield , brought him to the attention of the French avant-garde. After  the mid 1960s his plays evolved into what he termed Theatre Panique  (�Panic Theater�); typical of this period is And They Put Handcuffs on the  Flowers.

The silver  ore was crushed and ground by mule power in the arrastras (shallow cir�  cular pits paved with stone). Large blocks of stone attached by beams to  a central rotating post were dragged around the arrastra, reducing the ore  to a fine mud. Further steps resulted in the isolating of the silver.</p><p>arrest Restraint and seizure of a person by someone (e.g., a police  officer) acting under legal authority. An officer may arrest a person who  is committing or attempting to commit a crime in the officer�s presence.  Arrest is also permitted if the officer reasonably believes that a crime has  been committed and that the person arrested is the guilty party. A court  or judicial officer may issue an arrest warrant on a showing of probable  cause. Most states restrict or prohibit arrest in civil (noncriminal) cases;  an example of occasionally permitted civil arrest is the taking into cus�  tody of a debtor who might otherwise abscond. In the U.S., suspects must  be warned of their rights when they are arrested (see Miranda v. Arizona ).  An unlawful arrest is regarded as false imprisonment and usually invali�  dates any evidence collected in connection with it.

The term was derived retrospectively to distinguish  13th-century music from that of the 14th century (Ars Nova). It is partly  characterized by use of the six rhythmic modes, each being a rhythmic pat�  tern that would recur throughout a piece, such as long-short (first mode) or  short-long (second). Akin to the �feet� of poetry (see prosody), the relative  lengths of long and short depended on the mode. The system broke down  as composers began to use subdivisions of the short note. The musical  genres of the Ars Antiqua included organum and the early motet.</p><p>Ars Nova \'ars-'no-v9\ Latin "New Art" Musical style of 14th-  century Europe, particularly France. As composers began to use ever  shorter notes in their music, the old system of rhythmic modes (see Ars  Antiqua) ceased to be adequate to describe it. In his treatise Ars nova  (1323), Philippe de Vitry (1291-1361) proposed a way of relating longer  and shorter notes by a metrical scheme�the ancestor of time signatures�  whereby each note value could be subdivided into either two or three of  the next-shorter note. Though seemingly abstract, this innovation had a  marked effect on the sound of music because composers were better able  to control the relative motion of several voices, and 14th-century music  consequently sounds much less �medieval� to modern ears. De Vitry and  Guillaume de Machaut are the principal composers of the Ars Nova. The  term is sometimes extended to describe all 14th-century music, including  that of Italy.

It was  founded by Arsaces (r. c. 250-211? bc) of the Parni tribe, which origi�  nally dwelt east of the Caspian Sea and entered Parthia after the death of  Alexander the Great (323 bc), gradually extending control southward.

It controlled trade routes between Asia and the  Greco-Roman world and used its resultant wealth to erect many build�  ings. The dynasty was overthrown in 224 by the Sasanian dynasty.</p><p>arsenic poisoning Harmful</p><p>effects of arsenic compounds (in pesticides, chemotherapy drugs, paints,  etc.), most often from insecticide exposure. Susceptibility varies. Arsenic  is believed to combine with certain enzymes, interfering with cellular  metabolism. Symptoms of acute arsenic poisoning include nausea and  abdominal pain followed by circulatory collapse. Acute exposure to the  gas arsine causes destruction of red blood cells and kidney damage;  chronic exposure causes weakness, skin disorders, anemia, and nervous-  system disorders. Arsenic in urine and hair or nails is the key to diagno�  sis. Treatment involves washing out the stomach and promptly  administering the antidote dimercaprol.</p><p>arson Crime commonly defined by statute as the unlawful damage or  destruction of property by means of fire or explosion. In nearly all coun�  tries (except Great Britain) an arsonist is guilty of murder if someone dies  as a result of his action, even if he did not intend to kill. Germany and  some U.S. states also impose serious penalties for arson when it is com�  mitted to conceal or destroy evidence of another crime. Although fire  caused by accident or ordinary carelessness is not arson, a person may be  guilty of arson if he causes a fire in reckless disregard of the consequences  of his actions.</p><p>art also called visual art A visual object or experience consciously  created through an expression of skill or imagination. The term art encom�  passes diverse media such as painting, sculpture, printmaking, drawing,  decorative arts, photography, and installation. The various visual arts exist  within a continuum that ranges from purely aesthetic purposes at one end  to purely utilitarian purposes at the other. This should by no means be</p><p>taken as a rigid scheme, however, particularly in cultures in which every�  day objects are painstakingly constructed and imbued with meaning. Par�  ticularly in the 20th century, debates arose over the definition of art.  Figures such as Dada artist Marcel Duchamp implied that it is enough for  an artist to deem something �art� and put it in a publicly accepted venue.  Such intellectual experimentation continued throughout the 20th century  in movements such as conceptual art and Minimalism. By the turn of the  21st century, a variety of new media (e.g., video art) further challenged  traditional definitions of art. See aesthetics; art conservation and restora�  tion; drawing; painting; printmaking; sculpture; photography; decorative arts.</p><p>art brut V.art-'briit, ar-'brCet\ French "raw art" Art produced by  people outside the established art world, particularly crude, inexperienced,  or obscene works created by the untrained or the mentally ill. The term  was coined by Jean Dubuffet, who regarded such works as the purest form  of expression. See also naive art.</p><p>art collection Works of art accumulated by an individual or institution.  Such collections were made in the earliest civilizations; precious objects  were stored in temples, tombs, sanctuaries, and palaces. A taste for col�  lecting per se developed in Greece (4th� 1 st century bc). The great art col�  lections of the world grew out of private collections formed by royalty,  aristocracy, and the wealthy. By the 18th century, collectors were donat�  ing their holdings to the public and constructing buildings to house them  (e.g., the Louvre Museum, Uffizi Gallery). Wealthy industrialists in the U.S.  played a prominent role in the 19th-20th century, and an unprecedented  flow of masterpieces from Europe soon filled U.S. museums.</p><p>art conservation and restoration Maintenance and preservation  of works of art, their protection from future damage, deterioration, or  neglect, and the repair or renovation of works that have deteriorated or  been damaged. Research in art history has relied heavily on 20th- and  21st-century technical and scientific advances in art restoration. Modern  conservation practice adheres to the principle of reversibility, which dic�  tates that treatments should not cause permanent alteration to the object.</p><p>art criticism Description, interpretation, and evaluation of works of art,  manifested in journal reviews, books, and patronage. Art criticism encom�  passes a wide variety of approaches, from critical commentary to more  subjective emotional reactions inspired by viewing works of art. Art criti�  cism as a distinct discipline developed parallel to Western aesthetic theory,  beginning with antecedents in ancient Greece and fully taking form in the  18th and 19th centuries. In the 20th century perceptive critics became  champions of new artistic movements. Beginning in the 20th and con�  tinuing into the 21st century, many critics used social and linguistic, rather  than aesthetic, theoretical models. Prominent art critics include Roger Fry,  Clive Bell, Clement Greenberg, Harold Rosenblum, Lawrence Alloway,  Rosalind Krauss, and Donald Kuspit.

Its products included both individually crafted luxury items and  mass-produced wares, but, in either case, the intention was to create a  sleek and antitraditional elegance that symbolized wealth and sophistica�  tion. Influenced by Art Nouveau, Bauhaus, Cubist, Native American, and  Egyptian sources, the distinguishing features of the style are simple, clean  shapes, often with a �streamlined� look; ornament that is geometric or  stylized from representational forms; and unusually varied, often expen�  sive materials, which frequently include man-made substances (plastics,  especially bakelite; vita-glass; and ferroconcrete) in addition to natural  ones (jade, silver, ivory, obsidian, chrome, and rock crystal). Typical  motifs included stylized animals, foliage, nude female figures, and sun  rays. New York City�s Rockefeller Center (especially its interiors super�  vised by Donald Deskey), the Chrysler Building by William Van Alen, and  the Empire State Building by Shreve, Lamb &amp; Harmon are the most monu�  mental embodiments of Art Deco.</p><p>Art Ensemble of Chicago U.S. jazz ensemble. The group evolved  from the Association for the Advancement of Creative Musicians  (AACM), an experimental collective. Saxophonists Roscoe Mitchell and  Joseph Jarman, trumpeter Lester Bowie, bassist Malachi Favors, and  drummer Don Moye formed the group in 1969, combining freely chang�  ing tempos, dynamics, and textures with an often comic theatricality of  presentation. Their diversity of inspiration is expressed by their motto,  �Great Black Music: Ancient to the Future.�</p><p>arsenic Nonmetallic to semimetallic chemical element, chemical symbol</p><p>As, atomic number 33. It exists  uncombined in two stable (and sev�  eral unstable) allotropes, one gray  and one yellow, but is more often  found in nature as the sulfide or oxide.  The elemental form is used to form  alloys of metals (especially lead), and  certain semiconductors are made from  crystals of gallium arsenide (GaAs).  Arsenious oxide (arsenic trioxide or  white arsenic, As 2 0 3 ) is used in pes�  ticides, as a pigment, and as a preser�  vative of hides and wood; this is the  poisonous �arsenic� (see arsenic poi�  soning) in detective stories.

The analysis of symbols, themes, and subject matter is often of  primary concern. In the 20th and 21st centuries art historians became  increasingly concerned with the social and cultural context of artists and  their work.</p><p>Art Institute of Chicago Museum in Chicago that houses European,  American, Asian, African, and pre-Columbian art. It was established in  1866 as the Chicago Academy of Design and took its current name in  1882. In 1893 it moved to its present building, designed by the architec�  tural firm of Shepley, Rutan, and Coolidge for the World�s Columbian  Exposition, on Michigan Avenue. The Art Institute, which comprises both  a museum and a school, is noted for its extensive collections of 19th-  century French painting (Impressionist works and the work of Claude Monet  in particular) and 20th-century European and American painting. Among  its best-known works are Georges Seurat�s A Sunday Afternoon on La  Grand Jatte�1884 (1884-86), Grant Wood�s American Gothic (1930),  and Edward Hopper�s Nighthawks (1942).</p><p>Art Nouveau V.art-nii-'vo, .ar-nii-'voX Decorative style that flourished  in western Europe and the U.S. c.</p><p>1890-1910. The term was derived in  1895 from a gallery in Paris called  L�Art Nouveau. Characterized by  sinuous, asymmetrical lines based on  plant forms, the style was used in  architecture, interior design, graphic  art and design, jewelry, and glass. It  was international in scope, with cel�  ebrated exponents in England  (Aubrey Beardsley), Paris (Alphonse  Mucha), the U.S. (Louis Comfort Tif�  fany), Scotland (Charles Rennie  Mackintosh), Spain (Antonio Gaudi),  and Belgium (Victor Horta).

Uniramia, the largest of the arthropod subphyla, contains mostly terrestrial insects and myriapods (including centipedes and millipedes). The  insects, the largest arthropod class, differ from other arthropods in that they are usually winged and have only three pairs of legs. Members of the Crustacea subphylum are  mostly marine-dwelling and include the shrimps, lobsters, crabs, and barnacles. The microscopic water fleas are chiefly found in fresh water and, along with other minute  members of this subphylum, are part of the zooplankton. Most members of the Chelicerata subphylum are arachnids, including the spiders, scorpions, ticks, and mites. The  trilobites (members of the Trilobita subphylum) are extinct marine arthropods that flourished during the Cambrian Period.

All arthropods are bilaterally  symmetrical and possess a segmented body covered by an exoskeleton  containing chitin, which serves as both armour and a surface for muscle  attachment. Each body segment may bear a pair of jointed appendages.  The phylum includes carnivores, herbivores, omnivores, detritus feeders,  filter feeders, and parasites (see parasitism) in nearly all environments, both  aquatic and terrestrial.

He  practiced law in New York City from 1854, later becoming a close asso�  ciate of Sen. Roscoe Conkling, the Republican boss of New York. With  Conkling�s backing, he was appointed customs collector for the port of  New York (1871-78), an office long known for its use of the spoils sys�  tem. He conducted the business of the office with integrity but continued  to pad its payroll with Conkling loyalists. At the Republican national con�  vention in 1880, Arthur was the compromise choice for vice president on</p><p>a ticket with James Garfield; he became president on Garfield�s assassina�  tion. As president, Arthur displayed unexpected independence by vetoing  measures that rewarded political patronage. He also signed the Pendleton  Civil Service Act, which created a civil-service system based on merit. He  and his navy secretary recommended appropriations that later helped  transform the U.S. Navy into one of the world�s great fleets. He failed to  win his party�s nomination for a second term.</p><p>Arthurian legend Body of stories and medieval romances centring  on the legendary English king Arthur. The stories chronicle Arthur�s life,  the adventures of his knights, and the adulterous love between his knight  Sir Lancelot and his queen, Guinevere. The legend was popular in Wales  before the 11th century, was brought into literature by Geoffrey of Mon�  mouth, and was adapted by other medieval writers, including Chretien de  Troyes, Wace, Layamon, and Sir Thomas Malory, becoming entwined with  legends of the Holy Grail. From Victorian times, when interest in the leg�  end revived, it has figured in major works by Alfred Tennyson (Idylls of  the King) and T.H. White (The Once and Future King). It is uncertain  whether Arthur was a historical figure. Medieval sources say he was a  6th-century warrior and champion of Christianity who united the British  tribes against the Saxon invaders, died in battle at Camlann c. 539, and  was buried at Glastonbury.

It provided for a confederation of sovereign states and gave  the Congress power to regulate foreign affairs, war, and the postal ser�  vice, to control Indian affairs, and to borrow money. Under the Articles,  Congress settled state claims to western lands and established the North�  west Ordinances. But Congress had no power to enforce its requests to the  states for money or troops, and by late 1786 the government had ceased  to be effective, as was demonstrated by Shays's Rebellion (1786-87) against  courts that had been enforcing seizures of property for debt. Delegates to  the Annapolis Convention called a meeting of all the states to amend the  Articles.</p><p>articulation In phonetics, the shaping of the vocal tract (larynx, phar�  ynx, and oral and nasal cavities) by positioning mobile organs (such as the  tongue) relative to other parts that may be rigid (such as the hard palate)  and thus modifying the airstream to produce speech sounds. Articulators  include the tongue, lips, teeth and upper gum ridge, hard and soft palate,  uvula, pharyngeal wall, and glottis. Primary articulation refers either to  where or how the vocal tract is narrowed or blocked to produce a con�  sonant, or to the tongue contour, lip shape, and larynx height that deter�  mine the sound of a vowel. Other articulators may be used to produce a  secondary articulation such as palatalization (the front of the tongue  approaching the hard palate), glottalization (complete or partial closure of  the vocal cords), or nasalization (simultaneous passage of air through the  nasal and oral tracts).</p><p>artificial heart Machine or mechanical pump that maintains blood cir�  culation in the human body. The heart-lung machine, a mechanical pump,  can maintain circulation for a few hours while the heart is stopped for  surgery. It shunts blood away from the heart, oxygenates it, and returns it  to the body. No device has yet been developed for total, long-term replace�  ment of the heart; existing artificial hearts reduce the heart�s workload by  pumping between beats or acting as an auxiliary ventricle and are suit�  able only as temporary replacements in patients awaiting transplant. See  also PACEMAKER.</p><p>artificial insemination Introduction of semen into a female�s vagina  or cervix by means other than sexual intercourse. First developed for ani�  mal breeding in the early 20th century in Russia, it is now also used to  induce pregnancy in women whose partners cannot impregnate them. The  partner�s (or other donor�s) semen is inserted with a syringe. Though rea�  sonably successful, artificial insemination in humans raises moral issues  that are not yet fully resolved. In livestock, deep-frozen semen from a  male animal can be stored for long periods without losing its fertility, thus  allowing a single bull to sire as many as 10,000 calves a year.</p><p>artificial intelligence (Al) Ability of a machine to perform tasks  thought to require human intelligence. Typical applications include game  playing, language translation, expert systems, and robotics. Although  pseudo-intelligent machinery dates back to antiquity, the first glimmer�  ings of true intelligence awaited the development of digital computers in  the 1940s. AI, or at least the semblance of intelligence, has developed in  parallel with computer processing power, which appears to be the main  limiting factor. Early AI projects, such as playing chess and solving math�  ematical problems, are now seen as trivial compared to visual pattern rec�  ognition, complex decision making, and the use of natural language. See  also Turing test.</p><p>artificial respiration Breathing induced by any of several techniques  in a person who has stopped or is having difficulty breathing. It consists  chiefly of keeping the air passage open and inducing inhalation and exha�</p><p>lation. It does not include chest compressions to maintain circulation (see  cardiopulmonary resuscitation). The primary method is mouth-to-mouth  breathing, in which the rescuer breathes into the victim�s mouth, with  pauses to allow exhalation.</p><p>Artigas \ar-'te-gas\, Jose Gervasio (b. June 19, 1764, probably  Montevideo [Uru.]�d. Sept. 23, 1850, Ibiray, near Asuncion, Para.) Sol�  dier and revolutionary leader regarded as the father of Uruguayan inde�  pendence. In his youth Artigas was a gaucho in what is now Uruguay.  Allied with the Buenos Aires junta, he fought for independence from  Spain and won a brilliant victory at Las Piedras. His insistence on fed�  eralism against the efforts of Buenos Aires to assert control over the entire  region led to civil war. He ruled over a portion of what is now Uruguay  and central Argentina until a Portuguese invasion forced him into exile  in 1820. Uruguay achieved independence in 1828.</p><p>artillery In modern military science, big guns such as cannons, howit�  zers, or mortars operated by crews and of a calibre greater than 15 mm.  The earliest artillery, introduced in the 14th century, were cannons and  mortars of bronze, brass, or iron mounted on two-wheeled carriages. Mod�  ern artillery dates from the second half of the 19th century, when advances  included steel gun barrels, more powerful gunpowders, and piston mount�  ings that held artillery carriages steady during recoil. Both powder and  projectile were encased in a shell, which allowed for faster loading. Since  World War II, artillery has been ranked as light (up to 105 mm, for support  of ground troops), medium (106-155 mm, for bombardment), and heavy  (over 155 mm, for attacking rear installations). See also antiaircraft gun.</p><p>Arts and Crafts movement English social and aesthetic movement  of the second half of the 19th century, dedicated to reestablishing the  importance of craftsmanship in an era of mechanization and mass pro�  duction. The name derives from the Arts and Crafts Exhibition Society  (1888). Inspired by John Ruskin and other writers who deplored the effects  of industrialization, William Morris founded a firm of interior designers  and manufacturers to produce handcrafted textiles, printed books, wall�  paper, furniture, jewelry, and metalwork. The movement was criticized as  elitist and impractical in an industrial society, but in the 1890s its appeal  widened and spread to other countries, including the U.S. See also Art  Nouveau.</p><p>An English room decorated by William Morris in the Arts and Crafts style.</p><p>COURTESY OF THE VICTORIA AND ALBERT MUSEUM, LONDON, PHOTOGRAPH, JOHN WEBB</p><p>Aru Va-.rtA Islands Island group, eastern Indonesia. The easternmost  island group of the Moluccas, located off southwestern New Guinea, it  stretches north-south about 110 mi (180 km) and extends some 50 mi (80  km) east-west. The group consists of six main islands (Warilau, Kola,  Wokam, Kobroor, Maikoor, and Trangan), which are separated by narrow  channels, and dozens of smaller islands. Dobo, on Wamar Island, is the  principal harbour. The islands became part of Indonesia in 1949.</p><p>Aruba Island (pop., 2005 est.: 97,400), Lesser Antilles, off northwest�  ern Venezuela.

Aruba�s lack of water severely limits agriculture. The large petroleum�  refining complex there, once the island�s main employer, reopened after  closing in the mid-1980s, but tourism has become the island�s economic  mainstay. The earliest inhabitants were Arawak Indians, whose cave draw�  ings can still be seen. Though the Dutch took possession of Aruba in 1636,  they did not begin to develop it aggressively until 1816. The Netherlands  controls Aruba�s defense and foreign affairs, but internal affairs are  handled by an island government directing its own judiciary and currency.  In 1986 Aruba seceded from the Federation of the Netherlands Antilles in  an initial step toward independence.</p><p>arugula \3-'ru-g3-l3\ or rocket Yellowish-flowered European herba�  ceous plant ( Eruca vesicaria sativa), of the mustard family, cultivated for  its foliage, which is used especially in salads.

He composed at least two works, Aryabhatiya (c. 499) and the now lost  Aryabhatasiddhanta, which circulated mainly in the northwest of India  and influenced the development of Islamic astronomy. Written in verse  couplets, Aryabhatiya deals with mathematics and astronomy. Topics  include prediction of solar and lunar eclipses and an explicit statement</p><p>that the apparent westward motion of the stars is due to the spherical  Earth�s rotation about its axis. Aryabhata also correctly ascribed the lumi�  nosity of the Moon and planets to reflected sunlight.

From their language, also called Aryan, the Indo-European lan�  guages of South Asia are descended. In the 19th century there arose a  notion, propagated by the count de Gobineau and later by his disciple  Houston Stewart Chamberlain, of an �Aryan race�: people who spoke Indo-  European, especially Germanic, languages and lived in northern Europe.  The �Aryan race� was considered to be superior to all other peoples.  Although this notion was repudiated by numerous scholars, including  Franz Boas, the notion was seized on by Adolf Hitler and made the basis  of the Nazi policy of exterminating Jews, Gypsies (Roma), and other  �non-Aryans.� See also racism.</p><p>Asad, Hafiz al- See Hafiz al-AssAD</p><p>ASALA acronym for Armenian Secret Army to Liberate Arme�  nia Marxist-Leninist group formed in 1975 to force the Turkish govern�  ment to acknowledge the Armenian massacres of 1915 and pay reparations.

After studying in Rome  (1711-13), Cosmas Damian became a prolific fresco painter, and his  brother, Egid Quirin, became a sculptor and stuccoist. They developed  the effects of dramatic lighting and illusionism originated by Gian Lorenzo  Bernini and Andrea Pozzo. Working as a team, they produced magnificent  illusionistic decoration in ecclesiastical buildings, combining dramatic  lighting and colour. Their works are notable for their profound and dra�  matic intensity of religious feeling. The brothers became the principal late  Baroque exponents of illusionist decoration in religious architecture.  Their most notable collaboration is the church of St. John Nepomuk in  Munich (1733-46)�known as the Asamkirche in honour of the brothers.</p><p>Asante or Ashanti People of southern Ghana and adjacent areas of  Togo and Cote d�Ivoire. The largest segment of the Akan peoples, they  speak Twi, a language of the Kwa group of Niger-Congo languages; all  together the Akan peoples make up about half the population of Ghana.  Though some Asante now live and work in urban centres, most live in  villages and engage in agriculture. The symbol of Asante unity is the  Golden Stool, held to be so sacred that not even kings were allowed to  sit on it. The Asante supplied slaves to British and Dutch traders in  exchange for firearms, which they used to build up a large empire in the  18th and 19th centuries. They fought several wars against the British  (1824, 1863, 1869, 1874), finally losing their capital, Kumasi, in 1896.  Thereafter what remained of the empire went into decline.

Chrysotile accounts for about 95% of all asbestos still in com�  mercial use. The other types all belong to the amphibole group and include  the highly fibrous forms of anthophyllite, amosite, crocidolite, tremolite, and  actinoute. Asbestos fibre was used in brake linings, insulation, roofing  shingles, floor and ceiling tiles, cement pipes, and other building mate�  rials. Asbestos fabrics were used for safety apparel and theatre curtains.  In the 1970s it was found that prolonged inhalation of the tiny asbestos  fibres can cause asbestosis, lung cancer, and/or mesothelioma, all serious  lung diseases. The incidence of mesothelioma is most commonly associ�  ated with extensive inhalation of amphibole asbestos.

The Book of Acts relates that, after several appear�  ances to the Apostles over a period of 40 days, Jesus was taken up in their  presence and hidden behind a cloud, a symbol of God�s presence. The  event is thought to indicate a new relationship between Jesus and God  and between Jesus and his followers.

Most reli�  gions have some features of asceticism. The desire for ritual purity in  order to come in contact with the divine, the need for atonement, and the  wish to earn merit or gain access to supernatural powers all are reasons  for ascetic practice. Christian hermits and monks, wandering Hindu ascet�  ics, and Buddhist monks all reject worldly goods and practice various  forms of self-denial, including celibacy, abstinence, and fasting. Mem�  bers of the Digambara sect of Jainism practice an extreme form of asceti�  cism that includes the rejection of wearing clothes. Though monasticism  is rejected in the Qur�an, ascetic movements such as zuhd have arisen in  Islam. Zoroastrianism forbids fasting and mortification.</p><p>Asch \'ash\, Sholem (b.

It is located on the Tigris River,  60 mi (97 km) south of Mosul, Iraq. The name Ashur was applied to the  city, to Assyria itself, and to Assyria�s principal god. The capital�s site  was originally occupied c. 2500 bc and later became part of Akkad. By  the late 12th century bc it was under Assyrian control.

The archaeological site has yielded fortifications, temples, and  palaces.</p><p>Ashurbanipal V.a-sor-'ba-ni-.paL (fl. 7th century bc) Last great Assyr�  ian king (r. 668-627 bc). He was  appointed crown prince of Assyria in  672 bc; his half-brother was  appointed crown prince of Babylo�  nia. On his father�s death, Ashurba�  nipal assumed full power without  incident. He quelled a rebellion in  Egypt and successfully besieged  Tyre. His half brother, who served  him in Babylonia peacefully for 16  years, joined a coalition of peoples  from outlying areas of the Assyrian  empire and plotted rebellion, but  Ashurbanipal discovered the plots  and, after a three-year siege, took  Babylon. By 639 bc he had the whole  known world under his control. A  person of religious zeal, he rebuilt or  adorned most of the major shrines of  Assyria and Babylonia. His principal  intellectual accomplishment was the  creation in Nineveh of the first sys�  tematically organized library in the  Middle East; the clay tablets col�  lected there preserved omen texts,</p><p>Mesopotamian epics, prayers and  incantations, scientific texts, lexico�  graphical texts, and folktales.</p><p>Asia Largest continent on Earth. It  is bounded by the Arctic, Pacific, and</p><p>Indian oceans. The western boundary, with Europe, runs roughly north-  south along the eastern Ural Mountains; the Caspian, Black, Aegean, and  Mediterranean seas; the Suez Canal; and the Red Sea. The islands of Sri  Lanka and Taiwan and the archipelagoes of Indonesia (excluding New  Guinea), the Philippines, and Japan also form part of Asia. Area:  17,226,000 sq mi (44,614,000 sq km). Population (2004 est.):  3,879,659,000. Mountains and plateaus predominate on the continent,  with the highest mountains located in Central Asia and north of the Indian  subcontinent. Terrain features include Earth�s highest peak, Mount Ever�  est, at 29,035 ft (8,850 m), and the lowest natural point, the Dead Sea, at  1,312 ft (400 m) below sea level. The largest of Asia�s many arid regions  are the Thar and Gobi deserts. It has some of the longest rivers in the world,  including the Euphrates, Tigris, Indus, Ganges (Ganga), Yangtze (Chang;  the longest river in Asia), Huang He (Yellow), Ob, Yenisey, and Lena. The  Caspian, Aral, and Dead seas are major saltwater lakes. About one-fifth  of Asia�s landmass is arable. Its principal language groups include Sino-  Tibetan, Indo-Aryan, Austronesian, Austroasiatic, and Semitic; important  singular languages include Japanese and Korean. East Asia contains three  main ethnic groups: Chinese, Japanese, and Korean. The Indian subcon�  tinent is home to a vast diversity of peoples, most of whom speak lan�  guages from the Indo-Aryan subgroup of the Indo-European family.  Because of the influence of China and the former Soviet Union, the Man�  darin Chinese dialect and the Russian language are used widely. Asia is  the birthplace of all the world�s major religions and hundreds of minor  ones. Hinduism is the oldest major religion to have originated in southern  Asia; Jainism and Buddhism emerged in the 6th and 5th centuries bc, respec�  tively. Southwest Asia was the cradle of the so-called Abrahamic reli�  gions: Judaism, Christianity, and Islam. Daoism and Confucianism, both of  which originated in the 6th or 5th century bc, have profoundly influenced  Chinese culture and the cultures of surrounding peoples. Asia is marked  by great disparities in wealth. A few countries, notably Japan, Singapore,  and the oil-rich countries of the Arabian Peninsula, have attained high  standards of living; others, such as Bangladesh and Myanmar, are among  the poorest. Between these two extremes lie Russia, China, and India. Asia  is a land of great cultural diversity, but there are five main cultural influ�  ences: Chinese, Indian, Islamic, European, and Central Asian. China has  had great influence in East Asia as the source of Confucianism, artistic  styles, and the Chinese writing system. Indian influence has been  expressed through Hinduism and Buddhism, affecting Tibet, Indonesia,</p><p>Cambodia, and Central Asia. Islam spread from its original Arabian home  to become important in the Middle East, South Asia, Central Asia, and  elsewhere. Members of the earlier human species Homo erectus migrated  from Africa to East Asia at least one million years ago. One of the ear�  liest civilizations to use writing developed in the Tigris and Euphrates  river valleys c. 3000 bc (see Mesopotamia). Civilization in the Indus River  valley and in northern Syria followed c. mid-3rd millennium bc. Chinese  urban civilization began with the Shang dynasty (c. 1600-1046 bc) and  continued under the Zhou dynasty (1046-256 bc). Indo-European�  speaking peoples (Aryans) began to invade India from the west c. 2000-  1500 bc and developed the Vedic religion. A succession of empires and  charismatic rulers, including the Macedonian Alexander the Great, spread  their political control as far as military power could carry them. In the  13th century ad Genghis Khan and his Mongol successors united much  of Asia under their rule. In the 14th century the Turkic warlord Timur con�  quered much of Central Asia. Muslim Turks destroyed the remnants of  the Byzantine Empire in the 15th century. In the 19th century European  imperialism began to replace Asian imperialism. Tsarist Russia pushed its  political control across Asia to the Pacific Ocean, the British gained con�  trol of India and Burma (Myanmar), the French dominated eastern South�  east Asia (see French Indochina), the Dutch occupied the East Indies  (Indonesia), and the Spanish and later the U.S. ruled the Philippines. After  World War II (1939-45), European imperialism steadily disappeared as  former colonies gained independence in the second half of the 20th cen�  tury.

April 6, 1992, New York, N.Y., U.S.) Russian-born U.S. author and bio�  chemist. He arrived in the U.S. at age 3, earned a doctorate from Colum�  bia University, and subsequently taught for many years at Boston  University. Before embarking on graduate study, he had already begun  publishing his stories. �Nightfall� (1941) is often called the finest science-  fiction short story ever written. His I, Robot (1950) greatly influenced how  later writers treated intelligent machines. A trilogy of novels�  Foundation, Foundation and Empire, and Second Foundation (1951�  53)�is widely considered a classic. Asimov�s nonfiction science books  for lay readers are noted for their lucidity and humour. Immensely pro�  lific, he published more than 300 volumes in all.</p><p>Askja \'as-kya\ Caldera, Iceland.

Originally from Miletus, she lived with Peri�  cles from c. 445 bc until his death in 429. Because she was not a citizen,  their son was initially denied civic rights. Though an intellectual admired  by Socrates, she endured public attacks, especially in comic theatre, for  her private life and her supposed influence on Pericles� foreign policy.</p><p>Aspen City (pop., 2000: 5,914), western central Colorado, U.S. It is  located on the Roaring Fork River at the edge of the White River National  Forest, at an altitude of 7,907 ft (2,410 m). Founded by prospectors c.  1878, it was a booming silver-mining town by 1887 but declined rapidly  after silver prices collapsed in the early 1890s. Its revival as a ski resort  began in the late 1930s, and it is now a popular tourist town; it is also  known for its cultural festivals, notably the Aspen Music Festival.</p><p>aspen Any of three tree species of the genus Populus, of the willow  family: P. tremula (the common European aspen), P. tremuloides (the  American quaking, or trembling, aspen), and P. grandidentata (the Ameri�  can big-tooth aspen). Native to the Northern Hemisphere, aspens are  known for the fluttering of their leaves in the slightest breeze. Aspens  grow farther north and higher up the mountains than other Populus spe�  cies. All aspens have a smooth, gray-green bark, random branching, rich  green leaves that turn brilliant yellow in fall, and catkins that appear before  the leaves in spring.</p><p>Aspendus \as-'pen-d9s\ Ancient city, Pamphylia (now southwestern  Turkey).

Species for which the  sexual phase is known are placed in the order Eurotiales. A. niger causes  black mold on some foods; A. niger, A. flavus, and A. fumigatus cause  aspergillosis in humans. A. oryzae is used to ferment SAKE, and A. wentii  to process soybeans.</p><p>asphalt Black or brown petroleum-like material that has a consistency  varying from viscous liquid to glassy solid. It is obtained either as a resi�  due from the distillation of petroleum or from natural deposits. Asphalt  consists of compounds of hydrogen and carbon with minor proportions  of nitrogen, sulfur, and oxygen. It softens when heated and is elastic under  certain conditions. Used principally in road surfacing, asphalt is also used  for roofs, coatings, floor tilings, and waterproofing, and in industrial prod�  ucts.</p><p>asphodel Vas-f9-,del\ Any of several flowering plants belonging to the  lily family. This common name is variously applied and thus much misun�  derstood. The asphodel of the poets is often a narcissus; that of the ancients  is either of two genera, Asphodeline or Asphodelus. Asphodels are hardy  herbaceous perennials with narrow leaves and an elongated stem bearing  a handsome spike of white, pink, or yellow flowers.

Causes include stran�  gulation, drowning, and carbon monoxide poisoning. Breathing in food  or fluid can cause obstruction of the airway and pulmonary collapse.  Emergency resuscitation usually includes cardiopulmonary resuscitation.</p><p>aspidistra \ 1 as-po- , dis-tr9\ Any plant of the genus Aspidistra (lily fam�  ily), native to eastern Asia and known for ornamental foliage. The only  cultivated species is a houseplant commonly known as cast-iron plant (A.  elatior, or A. lurida ), which has long, stiff, pointed evergreen leaves that  are capable of withstanding temperature extremes, dust, smoke, and other  harsh conditions. The solitary, bell-shaped flowers, which are usually lilac  in colour but sometimes brown or green, are borne at the base of the plant.  The fruits are small berries.</p><p>aspirin Common name of acetylsalicylic acid, an organic compound  introduced in 1899. The ester of salicylic acid and acetic acid, it inhibits  production of prostaglandins in the body. Its analgesic, fever-reducing, and  anti-inflammatory effects make it useful in treating headaches, muscle and  joint aches, arthritis pain, and the symptoms of mild fevers and infections.  It also has anticoagulant activity and is taken in low doses by coronary  heart disease patients to prevent heart attack. Prolonged use may cause  stomach bleeding and peptic ulcer, and its use in children with fever has  been linked to Reye syndrome. See also acetaminophen; ibuprofen; NSAID.</p><p>Aspiring, Mt.

Elected to the House of Commons in 1886, he served as home secretary  (1892-95). A leader of the Liberal Party, he became prime minister in  1908. His plan to limit the powers of the House of Lords was enacted by  the Parliament Act of 1911. He led Britain in the early years of World  War I, but domestic crises combined with British losses in the war led to  widespread dissatisfaction. He resigned in 1916 but remained leader of  his party until 1926.</p><p>ass or wild ass Either of two species of small, sturdy equines. Asses  are 3-5 ft (90-150 cm) high at the shoulder. The African wild ass, or true  ass ( Equus asinus) is bluish gray to fawn; the Asiatic wild ass, or half�  ass ( E . hemionus) is reddish to yellow-gray. The half-ass differs from the  true ass in that it has extremely long, slender legs, shorter ears, and larger  hooves. The true ass has the alternating �hee-haw� bray.

He became air force  commander (1963) after helping the Ba'thists gain power. After partici�  pating in a military coup in 1966, he became minister of defense. He led  a coup in 1970 to replace his political mentor, Salah al-Jadld, as Syria�s  leader. He joined Egypt in a surprise attack on Israel (1973) but nearly  20 years later (1991) participated in peace negotiations with Israel in an  effort to regain the Golan Heights, taken by Israel in the Six-Day War of  1967.

The order takes its name from the pur�  ported use of hashish to induce ecstatic visions of paradise among its  devotees (hashshashun, �hashish smokers��whence is derived the  English term) before they set out to face martyrdom. The Assassins oper�  ated out of series of mountain fortresses and, seeing assassination as a  religious duty, engaged in a long campaign of murder against members  of the Sunnite community, including numerous officials of the 'Abbasid  and Seljuq dynasties, and others. The Assassins� power was finally bro�  ken by the Mongols, who captured the great Assassin stronghold of 'Ala-  mut in Iran in 1256. The Syrian branch was destroyed by the Mamluk  Baybars I in 1271-73. Leadership of the Nizari order continued until mod�  em times in the line of the Aga Khans, a family prominent worldwide as  philanthropists and public servants.</p><p>assassin bug Any of about 4,000 insect species (family Reduviidae)  characterized by a thin, necklike structure connecting the narrow head to  the body. Many species are common to North and South America. Rang�  ing in size from 0.5 to 1 in. (13-25 mm), assassin bugs use their short,  three-segmented beak to suck body fluids from their victims. Most assas�  sin bugs prey on other insects; some, however, suck blood from verte�  brates, including humans, and transmit diseases. One species, the large  assassin bug, defends itself by accurately �spitting� saliva toxic enough  to blind a human.</p><p>assassin fly See robber fly</p><p>assault and battery Related but distinct crimes. Battery is the unlaw�  ful application of physical force to another; assault is an attempt to com�  mit battery or an act that may reasonably cause fear of imminent battery.  With manslaughter and murder (see homicide), these concepts are articu�  lated to protect against rude and undesired physical contact or the threat  of it. Battery requires no minimum degree of force, nor does it need to  be applied directly; administering poison and transmitting a disease may  both be battery. Accidents and ordinary negligence are not, nor is reason�  able force used in the performance of duty (e.g., by a police officer). See  also RAPE.</p><p>assault rifle Military firearm that is chambered for ammunition of  reduced size or propellant charge and has the capacity to switch between  semiautomatic and fully automatic fire. Light and portable, yet able to  deliver a high volume of fire with reasonable accuracy at modern combat  ranges of 1,000-1,600 ft (300-500 m), assault rifles have become the  standard infantry weapon of modern armies. Their ease of handling makes  them ideal for mobile assault troops crowded into personnel carriers or  helicopters, as well as for guerrilla fighters engaged in jungle or urban  warfare. Widely used assault rifles are the U.S. Ml 6, the Soviet Kalash�  nikov (the AK-47 and modernized versions), the Belgian LAL and LNC,  and the German G3.</p><p>assaying Va-sa-iqX In chemical analysis, the process of determining  proportions of metal, particularly precious metal, in ores and metallurgi�  cal products. The most important assaying technique grew largely out of  the experiments of the ancient alchemists and goldsmiths. Precious met�  als tend to occur as scattered particles randomly distributed, so a large  sample of ore is required. Such large samples (typically containing gold,  silver, and lead) are still most economically assayed by this ancient  method, which involves several steps of heating and cooling. More  sophisticated recent methods, such as spectrochemical analysis, are not  suited to assaying precious metal ores because the samples of the inho�  mogeneous ore that must be used are larger than the instruments can  handle.

The term, coined by Jean Dubuffet in the 1950s, has been applied  to collage, photomontage, and sculptural assemblage. The Dadaists and</p><p>Surrealists produced ready-made assemblages and elevated them to art by  simply exhibiting them. Later artists who have worked with the technique  include Louise Nevelson and Robert Rauschenberg.</p><p>Assemblies of God Largest Pentecostal denomination in the U.S. It  was formed in 1914 in Hot Springs, Ark., by the union of several small  Pentecostal groups. The Assemblies of God emphasize the centrality of  the Bible in Christian faith and worship. Instead of sacraments, the Assem�  blies have two ordinances, baptism by total immersion and the Lord�s Sup�  per. Personal sanctification is believed to happen gradually rather than  instantaneously, and millennial doctrines dealing with Christ�s Second  Coming and the establishment of the Kingdom of God are of great impor�  tance. The Assemblies of God have been very active in mission work in  the U.S. and overseas.

Computers produced by different manufacturers  have different machine languages and require different assemblers and  assembly languages. Some assembly languages can be used to convert  the code that programmers write (source code) into machine language  (readable by the computer), and have functions to facilitate programming  (e.g., by combining a sequence of several instructions into one entity).  Programming in assembly languages requires extensive knowledge of  COMPUTER ARCHITECTURE.</p><p>assembly line Industrial arrangement of machines, equipment, and  workers for continuous flow of workpieces in mass-production operations.  An assembly line is designed by determining the sequences of operations  for manufacture of each component as well as the final product. Each  movement of material is made as simple and short as possible, with no  cross flow or backtracking. Work assignments, numbers of machines, and  production rates are programmed so that all operations performed along  the line are compatible. Automated assembly lines (see automation) con�  sist entirely of machines run by other machines and are used in such  continuous-process industries as petroleum refining and chemical manu�  facture and in many modern automobile-engine plants.

It is carried out either by central gov�  ernment agencies or by local officials. Property may be assessed on the  basis of its annual rental value, as in Britain, or its capital value, as in the  U.S. Various methods are used to determine capital value, including analy�  sis of market data to estimate the property�s current market price, esti�  mation of the cost of reproducing the property minus accrued depreciation,  and capitalization of the property�s earnings.</p><p>assessor One with special knowledge of a subject who is appointed or  elected to assist a judge or magistrate in deciding a legal matter. In the  U.S., the term also designates an official who evaluates property for the  purposes of taxation. Assessors were appointed in the late 19th century  throughout Europe to try to limit the influence of the jury system, which  had been introduced in the wake of the French Revolution. Assessors thus  represented a return to the civil-law traditions of Europe.

It was later applied to special sessions of high courts in England  and France. Assize courts were abolished in most countries in the 20th  century, but in France they are still the courts of first instance in the han�  dling of serious crimes.</p><p>Associated Press (AP) Cooperative news agency, the oldest and larg�  est in the U.S. and long the largest in the world. Its beginnings trace to  1848, when six New York City newspapers pooled their efforts to finance  a telegraphic relay of foreign news brought by ships to Boston. In 1892  the modern AP was set up under the laws of Illinois; several years later  it moved to New York. Its restrictive controls on new memberships were  ended with federal antitrust prosecution in the 1940s. AP was the first  agency to devote a news wire to sports coverage (1946), and it distrib�  utes business news through a partnership with Dow Jones &amp; Co., Inc.  More than 15,000 organizations worldwide obtain news, photographs, and  illustrations from the agency. The AP Stylebook has become a standard  in many journalistic organizations.</p><p>association In psychology, the process of forming mental connections  or bonds between sensations, ideas, or memories. Though discussed by  the ancient Greeks (in terms of similarities, contrasts, and contiguities),  the �association of ideas� was first proposed by John Locke and subse�  quently examined by David Hume, John Stuart Mill, Herbert Spencer, and  William James. Ivan Pavlov used objective methods to study the phenom�  enon, resulting in his identification of the conditioned reflex (see condi�  tioning). Within psychoanalysis, the therapist encourages �free association�  in order to help identify latent conflicts. Practitioners of Gestalt psychol�  ogy and others have criticized associationist theories as too all-embracing,  while some theorists of cognitive psychology have made it central to their  theory of memory.</p><p>association football See football</p><p>Association of Caribbean States (ACS) Trading bloc composed  of 25 countries of the Caribbean basin. Responding to a proposal by Pres.  Bill Clinton for a Free Trade Area of the Americas (FTAA), existing  Caribbean-area trading blocs joined forces in 1995 to strengthen their  economic position and ease future integration into the FTAA. Prominent  in the ACS are the Caricom countries (13 English-speaking countries and  Suriname), which have been struggling toward a single market and  economy along the lines of the European Union. The ACS has addressed  such issues as unifying responses to natural disasters, ending the U.S.  embargo of Cuba, and ending shipments of nuclear materials through the  Panama Canal.</p><p>Association of Southeast Asian Nations See ASEAN</p><p>associative law Two closely related laws of number operations. In  symbols, they are stated: a + (b + c) = (a + b) + c, and a(bc ) = ( ab)c . Stated  in words: The terms or factors may be associated in any way desired and  the result will be the same. This holds for the numbers generally encoun�  tered: positive and negative, integral and fractional, rational and irrational,  real and imaginary. Exceptions occur (e.g., in nonassociative algebras and  divergent infinite series). See also commutative law, distributive law.</p><p>Assos See Assus</p><p>assumpsit \3-'s9mp-sit\ (Latin: �he has undertaken�) In common law,  an action to recover damages for breach of contract, especially an implied  or quasi contract. It developed in early English law as a form of recovery  for the negligent performance of an undertaking (e.g., failing to protect  from damage another�s goods in one�s care). Eventually, it came to cover  broader claims regarding failure to keep a promise. It remains available  as a contractual remedy in some U.S. jurisdictions.</p><p>Assus or Assos Ancient Greek city, southern Troas (now northwestern  Turkey). It was founded in the 1st millennium bc on the Gulf of Edremit,  opposite the island of Lesbos. It was long an important city and port. Aris�  totle taught there 348-345 bc, and it was the birthplace of the philoso�  pher Cleanthes (3317-232? bc).</p><p>Assyria Ancient empire, southwestern Asia. It grew from a small region  around Ashur (in modem northern Iraq) to encompass an area stretching  from Egypt to Anatolia. Assyria may have originated in the 2nd millen�  nium bc, but it came to power gradually. Its greatest period began in the  9th century bc, when its conquests reached the Mediterranean Sea under  Ashurnasirpal II (883-859), and again c. 746-609 bc, during the Neo-  Assyrian empire, when it conquered much of the Middle East. Its great�  est rulers during the latter period were Tiglath-pileser III, Sargon II,  Sennacherib, and Ashurbanipal. Famous for their cruelty and fighting prow�  ess, the Assyrians were also monumental builders, as shown by archaeo�  logical finds at Nineveh, Ashur, and Calah. The opulence of Ashurbanipal�s  court at Nineveh became legendary. Artistically, the Assyrians were par�  ticularly noted for their stone bas-reliefs. The kingdom was finally van�  quished in 612-609 bc by a coalition of Media and Babylonia (Chaldea).</p><p>Assyro-Babylonian language See Akkadian language</p><p>Astaire, Fred orig.

At age seven he began his popu�  lar vaudeville dance act with his  sister Adele, and they made their  Broadway debut in 1917; they con�  tinued dancing in stage hits until  Adele retired in 1932. Astaire�s suc�  cessful film appearances with Ginger  Rogers began with Flying Down to  Rio (1933) and continued until 1939.</p><p>In the 1940s and 1950s he danced  on-screen with Eleanor Powell, Cyd  Charisse, and Judy Garland. His  singing, though untrained, was  admired by the finest songwriters of  his time. He retired in 1971 but occa�  sionally appeared in films and on television. His combination of sophis�  ticated, seemingly effortless grace and technical virtuosity revolutionized  popular-dance performance.</p><p>Astana formerly (1992-98) Aqmola or Akmola \ak-'mo-b\  or(1961-92) Tselinograd Vtsi-'le-no-.graA City (pop., 1999: 319,318),  capital of Kazakhstan. Situated on the banks of the Ishim River in north-  central Kazakhstan, it was founded in 1824 as a Russian military outpost.  The city�s importance was enhanced by its location at the junction of the  Trans-Kazakhstan and South Siberian railways. It is in the centre of a  mineral-rich steppe region. In 1994 the Kazakh government began to  transfer the national capital from Almaty to Astana, changing the city�s  name in 1998.</p><p>Astarte \a-'star-te\ or Ashtart \'ash-,tart\ Goddess of the ancient  Middle East and chief deity of the Mediterranean seaports of Tyre, Sidon,</p><p>Assiniboin, placating the spirit of a  slain eagle, photograph by Edward S.

Astarte shared many qualities, and perhaps a common origin,  with her sister Anath. The goddess of love and war, Astarte was worshiped  in Egypt and in Canaan, as well as among the Hittites. Her Akkadian  counterpart was Ishtar. She is often mentioned in the Bible under the name  Ashtaroth; Solomon is said to have worshipped the goddess, and Josiah  destroyed the shrines dedicated to her. In Egypt she was assimilated with  Isis and Hathor; in the Greco-Roman world she was assimilated with Aph�  rodite, Artemis, and Juno.</p><p>aster Any of various chiefly fall-blooming, leafy-stemmed herbaceous  plants (Aster and closely related genera) in the composite family, often with  showy flowers. Included among the asters are many perennial wildflow-  ers and hundreds of garden varieties.</p><p>asteroid Any of the many small rocky objects found mainly in a flat  ring, or belt, between the orbits of Mars and Jupiter. It is thought that the  gravitational influence of what became Jupiter kept the asteroids from  aggregating into a single planet while the solar system was forming. Also  called minor planets, asteroids are smaller than any of the nine major  planets; only about 30 are more than 125 mi (200 km) across. Ceres is the  largest known asteroid. Millions of boulder-sized asteroidal fragments are  thought to exist in the solar system. Asteroids or their fragments regularly  strike Earth, plunging through the atmosphere as meteors to reach its sur�  face (see meteorite). Asteroids appear to be composed of carbonaceous,  stony, and metallic (mainly iron) materials. See also Earth-crossing aster�  oid; Trojan asteroids.</p><p>asthenosphere \as-'the-n3-,sfir\ Zone of the Earth�s mantle lying  beneath the lithosphere, believed to be much hotter and more fluid than the  lithosphere. The asthenosphere is thought to extend from about 60 mi (100  km) to about 450 mi (700 km) below the Earth�s surface.</p><p>asthma Vaz-mo\ Chronic disease with attacks of shortness of breath,  wheezing, and coughing from constriction and mucous-membrane swell�  ing in the bronchi (air passageways in the lungs). It is caused primarily  by allergy or respiratory infection. Secondhand smoke can cause asthma  in children. Asthma is common and runs in families; predisposition may  be hereditary. In established asthmatics, exercise, stress, and sudden  changes in temperature or humidity can bring on attacks. Attacks usually  last from a half hour to several hours; severe attacks can be fatal. Corti�  costeroids can control asthma; injections of epinephrine can relieve acute  attacks. Prevention involves avoiding exposure to allergens.</p><p>astigmatism No-'stig-mo-.ti-zonA Lack of symmetry in the curvature  of the cornea or, rarely, the lens of the eye. The unequal curvatures spread  light rays, preventing them from being sharply focused at a point on the  retina, causing blurring of part of the image. The effect of astigmatism  can also be produced by misalignment of the lens. Astigmatic vision is  corrected by means of lenses (see contact lens, eyeglasses) that refract the  light rays to the proper degree in the opposite direction of that produced  by the defects in curvature.</p><p>Astor, John Jacob orig. Johann Jakob Astor (b. July 17, 1763,  Waldorf, Ger.�d. March 29, 1848,</p><p>New York, N.Y., U.S.) German-born  U.S. fur magnate and financier. After  emigrating from Germany at age 17,  he opened a fur-goods shop in New  York c. 1786. By 1800 he was a  leader in the fur trade, and he estab�  lished the American Fur Co. He con�  trolled the fur trade with China  (1800-17) and in the Mississippi and  Missouri valleys (in the 1820s)  before selling his interests in 1834.</p><p>His investment in New York City real  estate became the foundation of the  family fortune. At his death, Astor  was the wealthiest person in the U.S.;  he willed $400,000 to found what  became the New York Public Library.</p><p>His son, William B. Astor (1792-  1875), greatly expanded the family  real-estate holdings, building more  than 700 stores and dwellings in the  city.</p><p>Astrakhan Vas-tr3-,kan\ City (pop., 2002: 506,400), southwestern Rus�  sia. It is situated on several islands in the delta of the Volga River. It was  the capital of a Tatar khanate that became independent of the Golden  Horde in the 13th century, and its location on caravan and water routes  made it a trading centre. Ivan IV (the Terrible) conquered Astrakhan in  1556, giving Russia control of the Volga. The Turks burned the city in  1569. It served as the base for the campaign of Peter I (the Great) against  Persia and later was given special trade privileges. Sites of interest include  a fortress and a cathedral.</p><p>astrolabe Type of early scientific instrument used for reckoning time  and for observational purposes.</p><p>Astrolabes can be traced to the 6th  century ad; they came into wide use  in Europe and the Islamic world in  the early Middle Ages and were  adopted by mariners by the mid-15 th  century. One widely used variety, the  planispheric astrolabe, can be  regarded as a rudimentary analog  computer. It enabled astronomers to  calculate the positions of the Sun and  prominent stars with respect to both  the horizon and the meridian.</p><p>astrology Divination that consists  of interpreting the influence of stars  and planets on earthly affairs and  human destinies. In ancient times it  was inseparable from astronomy. It  originated in Mesopotamia (c. 3rd  millennium bc) and spread to India,  but it developed its Western form in  Greek civilization during the Hellenistic period. Astrology entered Islamic  culture as part of the Greek tradition and was returned to European cul�  ture through Arabic learning during the Middle Ages. According to the  Greek tradition, the heavens are divided according to the 12 constella�  tions of the zodiac, and the bright stars that rise at intervals cast a spiri�  tual influence over human affairs. Astrology was also important in ancient  China, and in imperial times it became standard practice to have a horo�  scope cast for each newborn child and at all decisive junctures of life.  Though the Copernican system shattered the geocentric worldview that  astrology requires, interest in astrology has continued into modem times  and astrological signs are still widely believed to influence personality.</p><p>astronaut Person trained to pilot a spacecraft, operate any of its sys�  tems, or conduct research aboard it during spaceflights. The term com�  monly refers to those participating in U.S. space missions; cosmonaut is  the Russian equivalent. Extensive training, including classroom study of  technical subjects as well as practice in computer-controlled simulators  and full-sized mock-ups of spacecraft to experience free fall, prepares  astronauts physically and psychologically for space missions. Astronauts  also learn to use the control, communication, and life-support systems of  any given spacecraft and conduct difficult flight operations. See also Edwin  Aldrin; Neil Armstrong; Guion S.

Direct measurement  through the parallax method cannot be used for accurate determinations,  because the Sun�s glare blots out the light of the background stars nec�  essary to make the measurement. The most precise values have been  obtained by measuring the distance from Earth to other objects orbiting  the Sun. This indirect method requires an accurate proportional math�  ematical model of the solar system; once the distance to one planet or  other object is determined, then the distance to the Sun can be calculated.</p><p>astronomy Science dealing with the origin, evolution, composition,  distance, and motion of all bodies and scattered matter in the universe. The  most ancient of the sciences, it has existed since the dawn of recorded  civilization. Much of the earliest knowledge of celestial bodies is often  credited to the Babylonians.

In the  16th century, Nicolaus Copernicus assigned the central position to the Sun  (see Copernican system), ushering in the age of modern astronomy. The  17th century saw several momentous developments: Johannes Kepler�s  discovery of the principles of planetary motion, Galileo�s application of  the telescope to astronomical observation, and Isaac Newton�s formulation  of the laws of motion and gravitation. In the 19th century, spectroscopy  and photography made it possible to study the physical properties of  planets, stars, and nebulae, leading to the development of astrophysics. In  1927 Edwin Hubble discovered that the universe, hitherto thought static,  was expanding (see expanding universe). In 1937 the first radio telescope  was built. The first artificial satellite, Sputnik, was launched in 1957, inau�  gurating the age of space exploration; spacecraft that could escape Earth�s  gravitational pull and return data about the solar system were launched  beginning in 1959 (see Luna; Pioneer).

Starting in the 19th century, spectroscopy and photography were applied  to astronomical research, making it possible to study the brightness, tem�  perature, and chemical composition of cosmic objects. It was soon real�  ized that the properties of these bodies could be fully understood only in  terms of the physics of their atmospheres and interiors. X-ray astronomy,  GAMMA-RAY ASTRONOMY, INFRARED ASTRONOMY, ULTRAVIOLET ASTRONOMY, and RADIO  and radar astronomy are all basically concerned with extending electro�  magnetic coverage beyond the visible spectrum to constrain the physical  characteristics of astronomical objects.</p><p>Astruc \as-trIEk\ of Lunel orig. Abba Mari ben Moses ben  Joseph (b. 1250?, Lunel, near Montpellier, France�d. after 1306)  French Jewish scholar. He revered Maimonides but argued that Mai-  monides� followers undermined faith by reading the Bible allegorically.  Through letters he persuaded the powerful rabbi Solomon ben Abraham  Adret (1235-1310) of Barcelona, Spain, to forbid the study or teaching  of science and philosophy by those under 25 (1305). The resulting con�  troversy almost split the Jewish communities of France and Spain. A  schism was prevented when Philip IV of France expelled the Jews from  France in 1306, and Astruc settled in Majorca.</p><p>Asturias \as-'tur-e-os\ Autonomous community (pop., 2001: 1,062,998)  and province, on the Bay of Biscay, northwestern Spain. It occupies an  area of 4,094 sq mi (10,604 sq km); its capital is Oviedo. Coextensive  with the historical principality of Asturias, it is largely covered by moun�  tains that isolate it from other Spanish provinces. Its population and indus�  tries are concentrated in the Nalon River valley, whose extensive  coalfields make the province Spain�s mining centre. Conquered by the  Romans under Augustus in 25 bc, it was later ruled by the Visigoths. It  became part of the kingdom of Leon on the accession of Alfonso III in  866. It was made a principality in 1388, a province in 1838, and an  autonomous community in 1981.</p><p>Asturias \as-'tur-e-9s\, Miguel Angel (b. Oct. 19, 1899, Guatemala  City, Guat.�d. June 9, 1974,</p><p>Madrid, Spain) Guatemalan poet,  novelist, and diplomat. He moved to  Paris in 1923 and became a Surreal�  ist under the influence of Andre Bre�  ton. His first major works appeared  in the 1930s. He began his diplo�  matic career in 1946; it culminated  in his serving as ambassador to  France 1966-70. Asturias�s writings  combine a Mayan mysticism with an  epic impulse toward social protest,  especially against U.S. and oligar�  chic power. In Men of Maize (1949),  often considered his masterpiece, he  depicts the seemingly irreversible  wretchedness of the Indian peasant.</p><p>Other major novels, some of which  employ the style of magic realism,  are El Sehor Presidente (1946), a fictional denunciation of Guatemala�s  dictator; The Cyclone (1950); The Green Pope (1954); and The Eyes of  the Interred (1960). He won the Nobel Prize for Literature in 1967.</p><p>Asuncion Xa-.sun-'syonN in full Nuestra Senora de la Asuncion</p><p>City (pop., 2002 prelim.: 513,339), capital of Paraguay. It lies on the  Paraguay River near its confluence with the Pilcomayo River. Founded in  1537 by Spanish coNQUiSTADORes, it replaced Buenos Aires as the head�  quarters of Spanish colonial activities in eastern South America during  the period of the latter�s depopulation (1541-80). In 1731 Asuncion was  the site of one of the first major rebellions against Spanish rule. The city  declared independence from both Spain and Argentina in 1811. Today it  dominates social, cultural, and economic trends in Paraguay.</p><p>Asvaghosa V.ash-vo'-go-shoN (b. ad 80?, Ayodhya, India�d. 150?,  Peshawar) Indian philosopher and poet considered the father of Sanskrit  drama. Born a Brahman, he opposed Buddhism until a debate with a Bud�  dhist scholar led to his conversion. Asvaghosa became known as a bril�  liant orator, and he spoke on Mahayana at the fourth Buddhist council. He  is considered India�s greatest poet before Kalidasa. Works attributed to  him include the Buddhacarita (�Life of the Buddha�) and the Mahalan-  kara (�Book of Glory�).</p><p>asvamedha V.ash-vo-'ma-doV Rite of the Vedic religion in ancient India,  performed by a king to celebrate his supremacy. A stallion was selected  and allowed to roam freely for a year under the protection of a royal guard.  It was said to symbolize the progress of the sun and the power of the  king. If it was not captured during the year, it was brought back to the  capital along with the rulers of lands it had entered. It was then sacrificed  at a public ceremony, and the king assumed the title of universal mon�  arch. The Buddha condemned the practice, but it was revived in the 2nd  century bc and may have continued as late as the 11th century ad.</p><p>Aswan City (pop., 1996 est.: 219,017), southeastern Egypt. It lies on  the Nile River just north of Lake Nasser. In ancient times it was the south�  ern frontier of pharaonic Egypt.

Modem  Aswan is located near the old Aswan Dam (completed 1902) and the  Aswan High Dam.</p><p>Aswan High Dam Dam across the Nile River, north of Aswan, Egypt.  Built 4 mi (6 km) upstream from the earlier Aswan Dam (1902), it is 364  ft (111 m) high and 12,562 ft (3,830 m) long. Differences with Gamal  Abdel Nasser led the U.S. and Britain to withdraw their financial support  of the project in 1956, whereupon Nasser turned to the Soviet Union for  assistance. The dam, completed in 1970, impounds the reservoir Lake  Nasser and controls the annual Nile flood, releasing flood waters when  needed for irrigation; it also enables the production of great amounts of  electric power. Its construction necessitated the relocation of the ancient  Abu Simbel ruins.</p><p>asylum Protection from arrest and extradition given to political refu�  gees by a country or by an embassy that has diplomatic immunity. No one  has a legal right to asylum, and the sheltering state, which has the legal  right to grant asylum, is under no obligation to give it. It is thus a right  of the state, not the individual. Its traditional use has been to protect those  accused of political offenses such as treason, desertion, sedition, and espio�  nage. Beginning in the 20th century, asylum also was granted to those  who could demonstrate a significant risk of politically motivated perse�  cution if they returned to their home countries.</p><p>asymmetric synthesis Chemical reaction by which unequal amounts  of two product isomers are formed. It is normally not possible to synthe�  size from materials that do not have optical activity (i.e., are not chiral) one  stereoisomer of a chiral compound without the other, but use of a chiral  auxiliary, such as an enzyme or other catalyst, a solvent, or an intermedi�  ate, can force the reaction to produce predominantly or only one isomer.  Asymmetric syntheses are often called stereoselective; if one product  forms exclusively, it is stereospecific.</p><p>asymptote Va-som-.toA In mathematics, a line or curve that acts as the  limit of another line or curve.

Extending north from the city of Copiapo, the area runs from north to  south for a distance of some 600 to 700 mi (1,000 to 1,100 km) and cov�  ers most of the Antofagasta region and the northern part of the Atacama  region. Because of its location between low coastal mountains and a  higher inland range, the region is meteorologically anomalous. Despite its  low latitude, summer temperatures average only about 65 �F (18 �C), and,  though heavy fogs are common, the desert is one of the driest regions in  the world. Some areas receive heavy rain only two to four times a cen�  tury. For much of the 19th century, the desert was the object of conflicts  between Chile, Bolivia, and Peru; after the War of the Pacific (1879-83),  Chile emerged with permanent ownership of sectors previously controlled  by Peru and Bolivia. For years before the development of synthetic meth�  ods of fixing nitrogen, the desert was a chief source of the world�s nitrates.</p><p>Atahuallpa \,a-ta-'wal-pa\ (b. c. 1502�d. Aug. 29, 1533, Cajamarca,  Inca empire) Last free-reigning emperor of the Incas. He became ruler  after defeating his half brother in what may have been the greatest mili�  tary engagement in Inca history. The conquistador Francisco Pizarro met  Atahuallpa just before the emperor�s triumphal entry into Cuzco and  invited him to a feast in his honour. When Atahuallpa and his unarmed  retainers arrived, Pizarro ambushed them on horseback with cannons and  guns, slaughtered thousands, and took Atahuallpa prisoner. Pizarro  accepted Atahuallpa�s offer of a ransom of a roomful of gold; then, hav�  ing received 24 tons of gold and silver, he ordered Atahuallpa burned at  the stake. The sentence was changed to death by garrote when Atahuall�  pa agreed to convert to Christianity.</p><p>Atalanta \,a-t 3 l-'an-t9\ In Greek mythology, a swift-footed huntress.

She was often depicted wearing a crown and carrying a sheaf of  grain, and her throne was supported by lions, suggesting her power over  nature. Considered a combination of Anath and Astarte, she also showed  kinship with the Anatolian Cybele (Great Mother of the Gods). Merchants  and mercenaries carried her cult throughout the Greek world, where she  was considered a form of Aphrodite.</p><p>Ataturk Yat-s-.torkV Mustafa Kemal orig. Mustafa Kemal (b.</p><p>1881, Salonika, Greece, Ottoman Empire�d. Nov. 10, 1938, Istanbul,  Tur.) Founder of modem Turkey. Dedicated by his father to military ser�  vice, he graduated near the top of his class in military school. As a young  officer, he was critical of the government of the Ottoman Empire and became  involved with the Turkish nationalist Committee of Union and Progress.  He nevertheless fought for the government during World War I (1914-18),  achieving great success against Allied forces during the Dardanelles Cam�  paign. The eventual Allied victory brought British, French, and Italian  troops to Anatolia; appointed to restore order there, he used the opportunity  to incite the people against the Allied occupation. Greece and Armenia, ter�  ritorial beneficiaries of the Ottoman defeat, opposed the Turkish national�  ists, but Mustafa Kemal overcame all opposition, and the Republic of  Turkey was established in 1923. He was given the name Ataturk (�Father  of the Turks�) in 1934. He pursued a policy of Westernization and secu�  larization, in which Western styles of dress and appellation were made  mandatory, seclusion of women was abolished, and the legal and educa�  tional system was overhauled.

Hereditary  ataxias are usually caused by degeneration of the spinal cord, cerebellum,  or other parts of the nervous system. The most common is Friedreich ataxia,  which begins at ages 3-5, progressing slowly to almost complete inca�  pacity by age 20. There is no specific therapy. Metabolic disorders, brain  injuries, and toxins can cause ataxia.</p><p>Atbara \'at-ba-ra\ River River, North Africa. Rising in the Ethiopian  highlands, it flows about 500 mi (800 km) northwest through eastern  Sudan to join the Nile River at Atbara in The Sudan. It is the Nile�s north�  ernmost tributary.</p><p>Atchafalaya Na-.cha-fs-'lI-sX Bay Inlet of the Gulf of Mexico on the  Louisiana coast, U.S. Together with Four League Bay, it extends about  21 mi (34 km). The Atchafalaya River links the bay with Morgan City on  the Gulf Intracoastal Waterway. The area includes many natural gas and  oil fields.</p><p>Atchafalaya River River, southern Louisiana, U.S. A distributary of  the Red and Mississippi rivers, it branches southwest from the Red River  in east-central Louisiana and flows south about 140 mi (225 km) to Atcha�  falaya Bay. Its name is Choctaw for �Long River.�</p><p>Atchison, Topeka and Santa Fe Railroad Co. Former railway.  Chartered in Kansas in 1860 by Cyrus K. Holliday, the founder of Topeka,  as the Atchison and Topeka Railroad Co., it was built along the Santa Fe  Trail and became known as the Santa Fe Railway. Its main line, completed  in 1872, extended to the Colorado state border. Further expansion west  in the 1880s and early 1890s reached about 9,000 mi (14,500 km) of track.  It reached its greatest extent in 1941, with more than 13,000 mi (21,000  km) of track, but gradually shrank thereafter. In 1971 its famously luxu�  rious passenger service was sold to Amtrak. In the 1990s it merged with  Burlington Northern to become Burlington Northern Santa Fe Railway.</p><p>atelectasis X.at-T-'ek-ts-sssV or lung collapse Lack of expansion of  pulmonary alveoli (see pulmonary alveolus). With a large-enough collapsed  area, the victim stops breathing. In adhesive atelectasis, obstruction or  lack of surface tension keeps a newborn�s alveoli from expanding. Com�  pression atelectasis is caused by external pressure. Obstructive atelecta�  sis may be caused by blockage of a major airway or when pain from  abdominal surgery keeps breathing too shallow to clear bronchial secre�  tions; treatment involves removal of obstruction or fluids, control of infec�  tion, and lung reinflation.</p><p>Aten See Aton</p><p>Atget \at-'zhe\, (Jean-) Eugene (-Auguste) (b.

He began his adult life as an itinerant actor. Around age 30 he  settled in Paris and became a photographer. The rest of Atget�s life was  spent recording everything he could that he considered picturesque or  artistic in and around Paris. With an eye for strange and unsettling images,  he made several series of photographs of iron grillwork, fountains, stat�  ues, and trees. He also photographed shop fronts, store windows, and poor  tradespeople. His main clients were museums and historical societies that  bought his photographs of historic buildings and monuments. After World  War I he received a commission to document the brothels of Paris. Man  Ray published four of Atget�s photographs in La revolution surrealiste  (1926), the only recognition he received in his lifetime. After his death,  Ray, Berenice Abbott, and the art dealer Julien Levy bought his remaining  collection, which is now in the Museum of Modem Art.</p><p>Athabasca, Lake Lake, western central Canada. It extends 208 mi  (335 km), crossing the Alberta-Saskatchewan boundary. On the southwest  it receives the Athabasca River, and on the northwest it discharges into the  Slave River. It is important for its commercial fishing.</p><p>Athabasca River River, west-central Canada. A tributary of the Mac�  kenzie River in Alberta, it rises in the Rocky Mountains in Jasper National  Park and flows northeast and north 765 mi (1,231 km) into Lake Atha�  basca. Its chief tributaries are the Pembina, Lesser Slave, McLeod, and  Clearwater rivers. Extensive petroleum deposits lie in oil-impregnated  sands (Athabasca Tar Sands) along a 70-mi (113-km) stretch of the river.</p><p>Athabaskan languages or Athapaskan languages Family  of North American Indian languages. There are perhaps 200,000 speak�  ers of Athabaskan. Northern Athabaskan includes more than 20 languages  scattered across an immense region of subarctic North America from  western Alaska to Hudson Bay and south to southern Alberta and British  Columbia. Pacific Coast Athabaskan consisted of four to eight languages,  all now extinct or nearing extinction. Apachean consists of eight closely  related languages spoken in the southwestern U.S. and northern Mexico,  including Navajo and the various subdivisions of Apache. In 1990 Navajo  had some 150,000 speakers, far more than any other indigenous language  of the U.S. or Canada. In 1915 Edward Sapir placed the Athabaskan fam�  ily together with Tlingit and Haida (languages of Alaska and British  Columbia, respectively) in a larger grouping called Na-Dene; this hypo�  thetical relationship continues to be controversial.</p><p>Athanasius V.a-tho-'na-zhosN, Saint (b. 293, Alexandria, Egypt�d.  May 2, 373, Alexandria; feast day May 2) Early Christian theologian and  staunch opponent of Arianism. He studied philosophy and theology at  Alexandria, Egypt, and in 325 he attended the Council of Nicaea, which  condemned the Arian heresy. He welcomed the council�s teaching that  the Son is �consubstantial with the Father� and defended that teaching  throughout his career. In 328 he was appointed patriarch of Alexandria,  but theological disputes led to the first of several banishments in 336. He  returned from exile repeatedly and resumed his office, but Arian opposi�  tion continued. After being banished by Constantius II in 356, Athanasius  lived in a remote desert in Upper Egypt and wrote theological treatises,  including his Four Orations Against the Arians. The emperor�s death in  361 gave Athanasius a brief respite under the toleration proclaimed by  Julian, but a controversy with Julian�s heathen subjects forced him to flee  into the Theban desert. At the time of his death he again possessed the  see at Alexandria.</p><p>atheism Va-the-.iz-onA Critique and denial of metaphysical beliefs in  God or divine beings. Unlike agnosticism, which leaves open the question  of whether there is a God, atheism is a positive denial. It is rooted in an  array of philosophical systems. Ancient Greek philosophers such as Dem�  ocritus and Epicurus argued for it in the context of materialism. In the 18th  century David Hume and Immanuel Kant, though not atheists, argued against  traditional proofs for God�s existence, making belief a matter of faith  alone. Atheists such as Ludwig Feuerbach held that God was a projection  of human ideals and that recognizing this fiction made self-realization  possible. Marxism exemplified modem materialism. Beginning with Friedrich  Nietzsche, existentialist atheism proclaimed the death of God and the  human freedom to determine value and meaning. Logical positivism holds  that propositions concerning the existence or nonexistence of God are  nonsensical or meaningless.</p><p>Athena \3-'the-n3\ or Athene \o-'the-ne\ In ancient Greek religion, the  goddess of war, handicraft, and wisdom and the patroness of Athens. Her  Roman counterpart was Minerva. Hesiod told how Athena sprang in full  armour from Zeus�s forehead. In the Iliad she fought alongside the Greek</p><p>heroes, and she represented the vir�  tues of justice and skill in warfare as  opposed to the blood lust of Ares. She  was associated with birds (especially  the owl) and the snake, and she was  usually represented as a virgin god�  dess. Her birth and contest with Posei�  don for suzerainty of Athens were  depicted on the Parthenon. Her birth�  day festival was the Panathenaea.</p><p>Athens Greek Athinai \a-'the-ne\</p><p>City (pop., 2001: 745,514), capital of  Greece. It is located inland near its  port, Piraeus, on the Saronic Gulf in  eastern Greece. The source of many  of the West�s intellectual and artistic  conceptions, including that of  democracy, Athens is generally con�  sidered the birthplace of Western  civilization. An ancient city-state, it  had by the 6th century bc begun to  assert its influence. It was destroyed  by Xerxes in 480 bc, but rebuilding  began immediately. By 450 bc, led  by Pericles, it was at the height of its  commercial prosperity and cultural  and political dominance, and over  the next 40 years many major build�  ing projects, including the Acropolis  and Parthenon, were completed.</p><p>Athens�s �Golden Age� saw the  works of the philosophers Socrates,</p><p>Plato, and Aristotle; the dramatists  Sophocles, Aristophanes, and Eurip-</p><p>ides; the historians Herodotus, Thucydides, and Xenophon; and the sculptors  Praxiteles and Phidias. The Peloponnesian Wars with Sparta ended in Ath�  ens�s defeat in 404, but it quickly recovered its independence and pros�  perity. After 338 bc Athens came under Macedonia�s hegemony, which  was lifted with the aid of Rome in 197 bc in a battle at Cynoscephalae. It  became subject to Rome in 146 bc. In the 13th century Athens was taken  by the Crusaders. It was conquered in 1456 by the Ottoman Turks, who  held it until 1833, when it was declared the capital of independent Greece.  Athens is Greece�s principal centre for business and foreign trade. The  city�s ruins and many museums make it a major tourist destination. It was  selected to host the 2004 Olympic Games.</p><p>The Varvakeion, a Roman marble copy  (c. ad 130) of the colossal gold and  ivory statue of the Athena Parthenos by  Phidias (438 bc); in the National  Archaeological Museum, Athens.</p><p>AUNARI/ART RESOURCE, NEW &gt;ORK</p><p>atherosclerosis or hardening of the arteries Chronic disease  characterized by abnormal thickening of the walls of the arteries due to  fatty deposits (atheromas) of cholesterol on the arterial inner walls (see-  artery). These thicken, forming plaques that narrow the vessel channel  (lumen) and impede blood flow. Scarring and calcification make the walls  less elastic, raising blood pressure. Eventually plaques may completely  block a lumen, or a blood clot (thrombus) may obstruct a narrowed chan�  nel. Atherosclerosis of one or more coronary arteries (also called coro�  nary heart disease) can decrease the heart muscle�s blood supply, causing  angina pectoris. Complete blockage causes heart attack. In the brain, ath�  erosclerosis may result in stroke. Treatments include drugs that reduce the  level of cholesterol and fat in the blood, anticoagulants and other drugs  that prevent the formation of blood clots, coronary bypass, and balloon  ANGIOPLASTY.</p><p>athlete's foot Form of ringworm that affects the feet. In the inflam�  matory type, the infection may lie inactive much of the time, with occa�  sional acute episodes in which blisters develop, mostly between the toes.

Chester Burton Atkins (b. June 20, 1924, Lut-  trell, Tenn., U.S.�d. June 30, 2001, Nashville, Tenn.) U.S. guitarist and  record company executive. Atkins began his musical career as a fiddler in  the early 1940s, but it was his signature style of playing guitar (bass rhythm  played with thumb, melody picked with three fingers) that brought him  worldwide acclaim. In the early 1950s he began playing electric guitar, pio�  neering its use in country music. As an RCA Records executive, he pro�  duced hit recordings for Elvis Presley, Jim Reeves, and Waylon Jennings.</p><p>Atlanta City (pop., 2000: 416,474; metro, area pop.: 4,112,198), capi�  tal of Georgia, U.S. Lying in the foothills of the Blue Ridge Mountains,  Atlanta is Georgia�s largest city. In 1837 a spot was selected there for a  railroad terminus that would serve the southeastern U.S. First named Ter�  minus and later Marthasville, it was given the name Atlanta in 1845. An  important supply depot during the American Civil War, it was burned by  Union forces under William T. Sherman. Atlanta became the state capital  in 1868. As it recovered from the war�s destruction, it began to epitomize  the spirit of the �New South� in seeking reconciliation with the North. It  was the home of Martin Luther King, Jr., and the first major Southern city  to elect a black mayor (1970). It is the principal trade and transportation  centre of the southeastern U.S.</p><p>Atlanta Campaign Important series of battles in the American Civil  War in Georgia (May-September 1864). Though most of the battles ended  in draws, they eventually cut off the main Confederate supply centre,  Atlanta. Union troops under William T. Sherman forced the evacuation of  the city (August 31-September 1) and then burned it. His victory assured  the reelection of Pres. Abraham Lincoln later that year.</p><p>Atlanta Compromise Classic statement on race relations by Booker  T. Washington, made in a speech at the Atlanta Exposition (1895). He  asserted that vocational education, which gave blacks a chance for eco�  nomic security, was more valuable than social equality or political office.  Many African Americans feared that such a limited goal would doom them  to indefinite subservience to whites; that fear led to the Niagara Move�  ment and later to the founding of the NAACP.</p><p>Atlanta Journal-Constitution Daily morning newspaper published  in Atlanta, Ga., based largely on the former Atlanta Constitution. Gener�  ally regarded as the �voice of the New South,� the Constitution counted  among the great newspapers of the U.S. It became a leader among South�  ern papers soon after its founding in 1868, and a succession of outstand�  ing editors contributed to its distinction: Henry W. Grady (1850-89), in  the late 1870s and 1880s; Clark Howell (1897-1938); and Ralph McGill,  who served as both editor (1942-60) and publisher (1960-69). In 1950 it  was bought by James M. Cox, who already owned the evening Atlanta  Journal (founded 1883); for many years a merged paper, the Atlanta  Journal-Constitution, was published on weekends until the two papers  were fully merged in 2001.</p><p>Atlantic Charter Joint declaration issued on Aug. 14, 1941, during  World War II, by Winston Churchill and Franklin D. Roosevelt. Among the  statements made in this propaganda manifesto, signed when the U.S. had  not yet entered the war, were that neither the U.S. nor Britain sought  aggrandizement and that both advocated the restoration of self-  government to peoples forcibly deprived of it. The charter was incorpo�  rated by reference in the Declaration of the UN (1942).</p><p>Atlantic City City (pop., 2000: 40,517) and resort, southeastern New  Jersey, U.S. Lying on narrow Absecon Island, the resort began to be  developed in the mid-19th century. Amusement piers were constructed,  and the first beachfront boardwalk was built there in 1870. The Miss  America Pageant was established in Atlantic City in 1921. After World  War II the city began to decline. In 1976 the state approved legalized</p><p>gambling, and extensive development in Atlantic City provided a huge  influx of money to the resort, but much of the surrounding area remained  impoverished.</p><p>Atlantic Intracoastal Waterway Navigable route, coastal eastern  U.S. Authorized by Congress in 1919 to provide sheltered passage for  both commercial shipping and pleasure craft, and constructed by the Army  Corps of Engineers, it was originally planned to form a continuous chan�  nel from New York City to Brownsville, Texas. Because the link through  Florida was never completed, it remains in two separate sections (see Gulf  Intracoastal Waterway). The Atlantic portion consists of rivers, bays, and  canals from Cape Cod to Florida Bay, including the Cape Cod Canal and  the Chesapeake and Delaware Canal.</p><p>Atlantic languages formerly West Atlantic languages Branch  of the Niger-Congo language family. Atlantic comprises some 45 lan�  guages spoken by some 30 million people living mainly in Senegal, The  Gambia, Guinea, Guinea-Bissau, Sierra Leone, and Liberia. About half of  these people speak Fula, the language of the Fulani. The languages of the  Wolof of Senegal and The Gambia and the Temne of northwest Sierra  Leone are spoken by more than 1 million people.</p><p>Atlantic Monthly, The Monthly journal of literature and opinion, one  of the oldest and most respected of U.S. reviews. Published in Boston, it  was founded in 1857 by Moses Dresser Phillips. It soon became noted for  the quality of its fiction and general articles, contributed by distinguished  editors and authors such as James Russell Lowell, Ralph Waldo Emerson,  Henry W. Longfellow, and Oliver Wendell Holmes. In the early 1920s it  expanded its scope to political affairs, featuring articles by figures such  as Theodore Roosevelt, Woodrow Wilson, and Booker T. Washington. In  the 1970s increasing costs nearly shut down the magazine; it was pur�  chased in 1980 by Mortimer B. Zuckerman and was sold to the National  Journal Group in 1999.</p><p>Atlantic Ocean Ocean separating North and South America from  Europe and Africa. The second largest of the world�s oceans, the Atlan�  tic has an area of 31,830,000 sq mi (82,440,000 sq km). With its marginal  seas, including the Baltic, North, Black, and Mediterranean to the east, and  Baffin Bay, Hudson Bay, the Gulf of St. Lawrence, Gulf of Mexico, and  Caribbean Sea to the west, it covers some 41,100,000 sq mi (106,450,000  sq km). Including these latter bodies of water, its average depth is 10,925  ft (3,330 m); its maximum depth is 27,493 feet (8,380 m) in the Puerto  Rico Trench. Its most powerful current is the Gulf Stream.</p><p>Atlantic salmon Oceanic trout species ( Salmo salar ), a highly prized  game fish. It averages about 12 lbs (5.5 kg) and is marked with round or  cross-shaped spots. Found on both sides of the Atlantic Ocean, it enters  streams in the fall to spawn. The young enter the sea in about two years  and mature in about four. Adults may return to the sea and, after a year  or two, spawn again. The ouananiche of rivers and the sebago, or lake,  salmon are landlocked subspecies that are also prized for sport. The Atlan�  tic salmon has been successfully introduced into the U.S. Great Lakes.</p><p>Atlantic, Battle of the Contest in World War II between Britain (and  later the U.S.) and Germany for the control of Atlantic sea routes. Ini�  tially the Anglo-French coalition drove German merchant shipping from  the Atlantic, but with the fall of France in 1940, Britain was deprived of  French naval support. The U.S. then assisted Britain with the lend-lease  program. Early in 1942, the Axis began a large-scale submarine offensive  against coastal shipping in U.S. waters, and German U-boats also oper�  ated in force along the South Atlantic ship lanes to India and the Middle  East. Allied shipping losses were severe, but the Allies succeeded in tight�  ening their blockade of Axis Europe and combating the Axis war on ship�  ping. By mid-1943 the Allies had recovered control of the sea routes.</p><p>Atlantis Legendary sunken island in the Atlantic Ocean west of Gibral�  tar. The main sources for the legend are two of Plato�s dialogues, Timaeus  and Critias. According to Plato, Atlantis had a rich civilization, and its  princes made many conquests in the Mediterranean before earthquakes  destroyed the island and it was swallowed up by the sea. Plato also sup�  plied a history of its ideal commonwealth, and Atlantis is sometimes  imagined as a utopia. The legend may have originated with the eruption  c. 1500 bc of a volcano on ThIra, which was so powerful that it gave rise  to earthquakes and tidal waves.</p><p>atlas Collection of maps or charts, usually bound together.

Such figures are  posed as if supporting great weights, like Atlas bearing the world. The  related telamon of Roman architecture, the male counterpart of the cary�  atid, is also a weight-bearing figure but does not usually appeal - in an atlas  pose.</p><p>Atlas In Greek mythology, the strong man who supported the weight of  the heavens on his shoulders. He was the son of the Titan Iapetus and the  nymph Clymene (or Asia) and the brother of Prometheus. According to  Hesiod, Atlas was one of the Titans who waged war against Zeus, and as  punishment he was condemned to hold aloft the heavens.</p><p>Atlas, Charles orig. Angelo Siciliano (b.

Roman launched a course involving isotonic exercises and  nutritional maintenance. Their mail-order bodybuilding course became  legendary through advertisements in three generations of pulp comic  books, the standard ad depicting scenes in which a skinny boy loses his  girlfriend to a well-built lifeguard (who kicks sand in his face) and regains  her after taking the Atlas course.</p><p>Atlas Mountains Mountain system, northwestern Africa. It extends  some 1,200 mi (2,000 km) from the Moroccan port of Agadir in the  southwest to the Tunisian capital of Tunis in the northeast. It comprises  several ranges, rising to various elevations, including the High Atlas in  Morocco; the Tell, or Maritime, Atlas, which runs along the coast from  Morocco to Tunisia; and the Saharan Atlas in Algeria, located farther  inland and running adjacent to the Sahara. Among these ranges are situ�  ated numerous plateaus and plains that support diverse ecologies. The  system�s highest peak is Morocco�s Mount Toubkal, elevation 13,665 ft  (4,165 m).</p><p>Atlas rocket Any of a series of U.S. expendable space launch vehicles.

The schools of Samkhya, Yoga, and Vedanta are  particularly concerned with atman. See also soul.</p><p>atmosphere Gaseous envelope that surrounds the Earth. Near the sur�  face it has a well-defined chemical composition (see air). In addition to  gases, the atmosphere contains solid and liquid particles in suspension.  Scientists divide the atmosphere into five main layers: in ascending order,  the troposphere (surface to 6-8 mi, or 10-13 km); the stratosphere (4-11  mi, or 6-17 km, to about 30 mi, or 50 km); the mesosphere (31-50 mi,  or 50-80 km); the thermosphere (50-300 mi, or 80-480 km); and the  exosphere (from 300 mi and gradually dissipating). Most of the atmo�  sphere consists of neutral atoms and molecules, but in the ionosphere a  significant fraction is electrically charged. The ionosphere begins near the  top of the stratosphere but is most distinct in the thermosphere. See also  ozone layer. See illustration opposite.</p><p>atmospheric pressure or barometric pressure Force per unit  area exerted by the air above the surface of the Earth. Standard sea-level  pressure, by definition, equals 1 atmosphere (atm), or 29.92 in.

It is usually measured with a mer�  cury barometer (hence the term barometric pressure), which indicates the  height of a column of mercury that exactly balances the weight of the</p><p>column of atmosphere above it. It may also be measured using an aner�  oid barometer, in which the action of atmospheric pressure in bending a  metallic surface is made to move a pointer.</p><p>atoll \'a- ,tol\ Coral reef enclosing a lagoon. Atolls consist of ribbons of  reef that may not be circular but that are closed shapes, sometimes miles  across, around a lagoon that may be 160 ft (50 m) deep or more. Most of  the reef itself is usually below the water surface; around the rim along the  top are usually low, flat islands or more continuous strips of low, flat land.</p><p>atom Smallest unit into which matter can be divided and still retain the  characteristic properties of an element. The word derives from the Greek  atomos (�indivisible�), and the atom was believed to be indivisible until  the early 20th century, when electrons and the nucleus were discovered.  It is now known that an atom has a positively charged nucleus that makes  up more than 99.9% of the atom�s mass but only about 1/100,000 of its  volume. The nucleus is composed of positively charged protons and elec�  trically neutral neutrons, each about 2,000 times as massive as an elec�  tron. Most of the atom�s volume consists of a cloud of electrons that have  very small mass and negative charge. The electron cloud is bound to the  nucleus by the attraction of opposite charges. In a neutral atom, the pro�  tons in the nucleus are balanced by the electrons. An atom that has gained  or lost electrons becomes negatively or positively charged and is called  an ion.

The original standard  of atomic weight, established in the 19th century, was hydrogen, with a  value of 1. From c. 1900 until 1961, the reference standard was oxygen,  with a value of 16, and the unit of atomic mass was defined as Vie the  mass of an oxygen atom. Oxygen, however, contains small amounts of  two isotopes that are heavier than the most abundant one, and 16 is actu�  ally a weighted average of the masses of the three isotopes of oxygen.  Therefore, the standard was changed to one based on carbon-12. The new  scale required only minimal changes to the values that had been used for  chemical atomic weights.</p><p>atomism Philosophical doctrine that material objects are aggregates of  simpler parts known as atoms. Atomism in the strict sense is character�  ized by three points: the atoms are absolutely indivisible, qualitatively  identical apart from shape, size, and motion, and combinable with each  other only by juxtaposition. Atomism is usually associated with realism  and mechanism; it is mechanistic because it maintains that all observable  changes can be reduced to changes in the configuration of the atoms that  constitute matter. It is opposed to holism because it holds that the prop�  erties of any whole can be explained in terms of those of its parts.</p><p>Aton or Aten Va-ton, 'a-ton\ In ancient Egyptian religion, a sun god,  depicted as the solar disk emitting rays terminating in human hands.

ATP�s  chemical bonds (see bonding) store a large amount of chemical energy.  ATP therefore functions as the carrier of chemical energy from energy-  yielding oxidation (see oxidation-reduction) of food to energy-demanding  cellular processes. Three such processes of metabolism are sources of ATP  and stored energy: fermentation, the tricarboxylic acid cycle, and cellular  respiration (also called oxidative phosphorylation). All form ATP from  adenosine monophosphate (AMP) or adenosine diphosphate (ADP) and  inorganic phosphate. When the reaction goes in the other direction, ATP  is broken down to ADP or AMP and phosphate, and the released energy  is used to perform chemical, electrical, or osmotic work for the cell.</p><p>atresia and stenosis \3- , tre-zh3...ste-'no-s3s\ Absence (atresia), usu�  ally congenital, or narrowing (stenosis) of almost any normal body cav�  ity or passage.

The most common major arrhyth�  mia, it may result as a consequence of increased fibrous tissue in the aging  heart, of heart disease, or in association with severe infection. If it con�  tinues, it can permit formation of blood clots, which can block blood flow  to essential organs. Emergency treatment consists of drugs such as beta-  blockers or digitalis, which slow the heart�s action, and anticoagulants. In  addition, atrial fibrillation can be interrupted by administering electric  shocks (defibrillation). See also ventricuiar fibrillation.</p><p>atrium Va-tre-onP In an ancient Roman house, an open central court  that contained the impluvium, a  basin where rainwater collected. It  originally contained the health and  functioned as the center of family  life. The term later came to be used  for the open front courtyard of a  Christian basilica, where congregants  collected before services. The atrium  was revived in the 20th century in  the form of glass-covered, greenery-  filled multistory spaces sometimes  found in shopping centers, office  buildings, and large hotels.</p><p>atrophy Va-tr9-fe\ Decrease from  previous normal size of the body or  a part, cell, organ, or tissue.

It works by suppressing the  parasympathetic nervous system. Atropine is also used as an antidote for  nerve gas poisoning.</p><p>Atsumi Kiyoshi (b. March 10, 1928, Tokyo, Japan�d. Aug. 4, 1996,  Tokyo) Japanese comic actor. Atsumi grew up in an impoverished section  of Tokyo and took odd jobs in the theatre before first portraying the role  of Tora-san for a television film in 1968. He went on to play the char�</p><p>acter until 1996 in the 48-film series Otoko wa tsurai yo (�It�s Tough  Being a Man�), the longest-running series in which the same actor por�  trayed the central character. Tora-san, a middle-aged peddler, is a charm�  ingly irresponsible rogue who sells trinkets to passersby and  unsuccessfully courts pretty women. Atsumi infused the role with witty  wordplay and a folksy sincerity.</p><p>attainder In English law, the extinction of civil and political rights after  a sentence of death or outlawry, usually after a conviction of treason. A  legislative act attainting a person without trial was known as a bill of  attainder. The most important consequences of attainder were forfeiture of  property and �corruption of blood,� meaning that the attainted person was  disqualified from inheriting or transmitting property, thus disinheriting his  descendants. All forms of attainder except forfeiture following indictment  for treason were abolished in the 19th century. As a result of the English  experience, the U.S. Constitution provided that �no Attainder of Treason  shall work Corruption of Blood, or Forfeiture except during the Life of the  Person attainted.� The U.S. Supreme Court has also struck down as bills  of attainder such things as the test oaths passed after the Civil War to dis�  qualify Confederate sympathizers from certain professions.</p><p>Attalus I Soter \ , at-3-bs... , s6t-3r\ (b. 269�d. 197 bc) Ruler of Perga-  mum (241-197).

As an independent producer,  he made innovative educational programs such as Life on Earth (1979)  and The Living Planet (1984). He was knighted in 1985.</p><p>attention In psychology, the act or state of applying the mind to an  object of sense or thought. Wilhelm Wundt was perhaps the first psycholo�  gist to study attention, distinguishing between broad and restricted fields  of awareness. He was followed by William James, who emphasized active  selection of stimuli, and Ivan Pavlov, who noted the role attention plays  in activating conditioned reflexes. John B. Watson sought to define atten�  tion not as an �inner� process but rather as a behavioral response to spe�  cific stimuli. Psychologists today consider attention against a background  of �orienting reflexes� or �preattentive processes,� whose physical corre�  lates include changes in the voltage potential of the cerebral cortex and in  the electrical activity of the skin, increased cerebral blood flow, pupil  dilation, and muscular tightening. See also attention deficit disorder.</p><p>attention deficit (hyperactivity) disorder (ADD or ADHD)  formerly hyperactivity Behavioral syndrome in children, whose major  symptoms are inattention and distracAbility, restlessness, inability to sit  still, and difficulty concentrating on one thing for any period of time. It  occurs in about 5% of all schoolchildren, and it is three times more com�  mon in boys than in girls. It can adversely affect learning, though many  children with ADD can learn to control their behaviour sufficiently to per�  form satisfactorily in school. It appears to be caused by a combination of  genetic and environmental factors. Certain aspects of the syndrome may  persist into adulthood. Treatment usually entails counseling and close  parental supervision, and it may also include prescription medication.</p><p>atthakatha \,a-t3-'ka-t3\ Commentaries on the Pali Buddhist canon  from ancient India and Ceylon.

Its coastal settlements were  enriched by maritime trade. Origi�  nally inhabited by Pelasgians, it was  a center of Mycenaean culture in the  2nd millennium bc; the Ionian  Greeks invaded it c. 1300 bc.

He was one of the greatest of  the barbarian rulers who assailed the  Roman Empire. He and his brother Bleda inherited an empire that stretched  from the Alps and the Baltic nearly to the Caspian Sea. The failure of the  Romans to pay promised tributes prompted Attila to launch assaults along  the Danube in 441 and 443. He murdered his brother in 445 and two years  later invaded the Balkan provinces and Greece, a campaign later ended by  another peace treaty that exacted heavy damages from the Eastern Romans.  He invaded Gaul (451) but was defeated by an alliance of the Roman gen�  eral Aetius and the Visigoths. His invasion of Italy (452) was ended by fam�  ine and plague. His depredations, which seemed to some like divine  punishment, earned him the epithet Flagellum Dei (�Scourge of God�).  Attila died on his wedding night, possibly murdered by his bride. His sons  took control of his empire, which collapsed shortly after Attila�s death.</p><p>Attis Mythical consort of the Great Mother of the Gods and vegetation  god worshiped in Phrygia and Asia Minor.

Attitudes reflect a tendency to classify objects and events and to react to  them with some consistency. Attitudes are not directly observable but  rather are inferred from the objective, evaluative responses a person  makes. Thus, investigators depend heavily on behavioral indicators of  attitudes�what people say, how they respond to questionnaires, or such  physiological signs as changes in heart rate. Attitude research is employed  by social psychologists, advertising professionals, and political scientists,  among others. Public-opinion researchers often attempt to distinguish atti�  tudes from related concepts such as values, opinions, and knowledge.</p><p>Attlee, Clement (Richard), 1 st Earl Attlee of Walthamstow</p><p>(b.

Committed to social  reform, he lived for much of the  years (1907-22) in a settlement  house in London�s impoverished  East End. Elected to Parliament in  1922, he served in several Labour  governments and in the wartime coa�  lition government of Winston  Churchill, whom he succeeded as  prime minister in 1945. Attlee pre�  sided over the establishment of the  WELFARE STATE in Britain, the national�  ization of major British industries,  and the granting of independence to  India, an important step in the con�  version of the British Empire into the  Commonwealth of Nations.

Typically, potential purchasers make a succession of increasing bids or  offers until the highest (and final) bid is accepted by the auctioneer. At a  so-called Dutch auction, by contrast, the seller offers property at succes�  sively lower prices until one of his offers is accepted or until the price  drops so low as to force the withdrawal of the offered property. Prospec�  tive buyers are usually allowed to examine auction items beforehand, and  sellers may set a minimum price below which the property will not be  sold. Auctions are important in the agricultural markets of many coun�  tries, permitting the rapid sale of perishable goods. Other items often sold  at auction include artwork and antiques, secondhand goods, and farms and  buildings repossessed by banks or the government.

Jan. 27, 1851, New York, N.Y.,  U.S.) U.S. ornithologist, artist, and naturalist known for his drawings and  paintings of North American birds. Bom to a French merchant in Haiti,  he returned with his father to France, where he briefly studied painting  with Jacques-Louis David before moving to the U.S. at age 18. From his  father�s Pennsylvania estate, he made the first American bird-banding  experiments. After failing in business ventures, he concentrated on draw�  ing and studying birds, which took him from Florida to Labrador. His  extraordinary four-volume Birds of America was published in London in  1827-38. He simultaneously published the extensive accompanying text  Ornithological Biography (5 vol., 1831-39). His multivolume Viviparous  Quadrupeds of North America (1842-54) was completed by his sons.  Though his bird poses are sometimes unrealistic (the result of painting  dead birds wired into position) and some details are inaccurate, few argue  with the excellence of his illustrations as art, and his studies were fun�  damental to New World ornithology.</p><p>Audubon Society, National U.S. organization dedicated to con�  serving and restoring natural ecosystems.

Its principal author was Philipp Melanchthon, and it was pre�  sented to Emperor Charles V at the Diet of Augsburg on June 25, 1530.  Its purpose was to defend the Lutherans against misrepresentations of  their teachings and to provide a statement of theology that Roman Catho�  lics might accept. It consisted of 28 articles that outlined Lutheran doc�  trine and listed abuses that had crept into Western Christendom over the  centuries. The unaltered document has remained authoritative for Luth�  erans, and a heavily revised version by Melanchthon is accepted by some  Reformed churches. Translated into English in 1536, it had a major influ�  ence on the Anglican Church�s Thirty-nine Articles and the Methodists�  Twenty-five Articles of Religion.</p><p>Augusta City (pop., 2000: 18,560), capital of Maine, U.S. It was estab�  lished in 1628 by traders from Plymouth colony as a post at the head of  navigation on the Kennebec River. Fort Western was built there in 1754  (restored 1922), attracting settlers. Incorporated in 1797, the town was  renamed the next year for the daughter of an American Revolutionary  general. It became the state capital in 1832. It is one of Maine�s leading  vacation centres.</p><p>Augustan Age ( c. 43 bc-ad 18) Illustrious period in Latin literary  history. Along with the preceding period, which was dominated by Cicero,  it forms the Golden Age of Latin literature. Marked by civil peace and  prosperity, the age reached its highest expression in poetry, with polished,  sophisticated verse on themes of patriotism, love, and nature, generally  addressed to a patron or to the emperor Augustus. Writers active in the  period include Virgil, Horace, Livy, and Ovid. The term is also applied to  �classical� periods in the literature of other nations, especially to late 17th-  and 18th-century England.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Augustine &#x25BA; Aurangzeb I 131</p><p>Augustine (of Hippo), Saint (b. Nov. 13,354, Tagaste, Numidia�d.  Aug. 28, 430, Hippo Regius; feast day August 28) Christian theologian  and one of the Latin Fathers of the Church. Born in Roman North Africa,  he adopted Manichaeism, taught rhetoric in Carthage, and fathered a son.  After moving to Milan he converted to Christianity under the influence  of St. Ambrose, who baptized him in 387. He returned to Africa to pursue  a contemplative life, and in 396 he became bishop of Hippo (now Annaba,  Alg.), a post he held until his death while the city was under siege by a  Vandal army. His best-known works include the Confessions, an autobio�  graphical meditation on God�s grace, and The City of God, on the nature  of human society and the place of Christianity in history. His theological  works On Christian Doctrine and On the Trinity are also widely read. His  sermons and letters show the influence of Neoplatonism and carry on  debates with the proponents of Manichaeism, Donatism, and Pelagianism.  His views on predestination influenced later theologians, notably John  Calvin. He was declared a Doctor of the Church in the early Middle Ages.</p><p>Augustine \o-'g9s-t9n\ of Canterbury, Saint (b. Rome?�d. May  26, 604/605, Canterbury, Kent, Eng.; feast day May 26 in England and  Wales, May 28 elsewhere) First archbishop of Canterbury. A Benedictine  prior in Rome, he was chosen by Pope Gregory I to lead 40 monks as  missionaries to England. They arrived in 597 and were welcomed by King  Ethelbert of Kent, at the behest of his queen, and he gave them a church  in Canterbury. Augustine converted the king and thousands of his sub�  jects and was made bishop of the English. On the pope�s instructions he  purified pagan temples and consecrated 12 other bishops. He founded  Christ Church, Canterbury, as his cathedral and made Canterbury the pri�  mary see in England. He tried unsuccessfully to unify his churches with  the Celtic churches of northern Wales.</p><p>Augustinian In the Roman Catholic church, a member of any of the  religious orders and congregations whose constitutions are based on the  Rule of St. Augustine, including the Hospitallers (Knights of Malta) and  the Dominicans. The two main branches of the Augustinians, however, are  the Augustinian Hermits and the Augustinian Canons. The former was  one of the four great mendicant orders of the Middle Ages, and its mem�  bers (including Martin Luther) were active in European university life and  ecclesiastical affairs. The latter became in the 11th century the first Roman  Catholic order to combine clerical status with full common life. The order  declined after the Reformation, but it continues missionary, educational,  and hospital work. Other notable orders are the Augustinian Recollects  (founded in the 16th century) and the Second Order of St. Augustine  (1264) for nuns, both still active today.</p><p>Augustus., Caesar or Octavian orig. Gaius Octavius later  Gaius Julius Caesar Octavianus (b. Sept. 23, 63 bc �d. Aug. 19,  ad 14, Nola, near Naples) First Roman emperor. Bom to a wealthy fam�  ily, at age 18 he was named adoptive son and heir of his great-uncle Julius  Caesar. After Caesar�s assassination (44 bc) a power struggle ensued, and  several battles later Octavian formed the Second Triumvirate with his chief  rivals, Lepidus and Mark Antony. Octavian disposed of Lepidus in 32 and  Antony (then allied with Cleopatra) at the Battle of Actium in 31 to become  sole ruler. He was anointed princeps; the Roman Empire is said to begin  with his accession. At first he ruled as consul, maintaining republican  administration, but in 27 he accepted the title Augustus and in 23 he  received imperial power. His rule (31 bc-ad 14) brought changes to every  aspect of Roman life and lasting peace and prosperity to the Greco-Roman  world. He secured outlying imperial provinces, built roads and public  works, established the Pax Romana, and fostered the arts. He took steps  to rectify Roman morality, even exiling his daughter Julia for adultery.  When he died, the empire stretched from Iberia to Cappadocia and from  Gaul to Egypt. He was deified after his death.</p><p>Augustus II Polish August Fryderyk (b. May 12, 1670, Dresden,  Saxony�d. Feb. 1, 1733, Warsaw) King of Poland and elector of Sax�  ony (as Frederick Augustus I). He ascended to the Polish throne in 1697,  having converted to Catholicism to better his chances. Also called Augus�  tus the Strong, he invaded Livonia in 1700, beginning the Second North�  ern War. Charles XII of Sweden defeated Augustus�s army and forced  him to abdicate in 1706, but he was restored as king in 1710. Poland  declined during Augustus�s reign from a major European power to a pro�  tectorate of Russia.</p><p>Augustus III Polish August Fryderyk (b. Oct. 17, 1696, Dresden,  Saxony�d.

He cared more for pleasure than affairs  of state and left the administration of Saxony and Poland to his chief  adviser, Heinrich von Bruhl (1700-1763), and the powerful Czartoryski  family. He gave Saxon support to Austria in the War of the Austrian Suc�  cession and the Seven Years' War.</p><p>auk In general, any of 22 species of diving birds (family Alcidae), espe�  cially the little auk and the razorbill, or razor-billed auk. Auks are 6-16  in. (15�40 cm) long, with short wings and legs and webbed feet. They  occur only in Arctic, subarctic, and temperate regions (with a few species  south to Baja California). Auks nest colonially on cliff ledges or in rock  crevices or burrows near the sea; many spend the winter far from land.  They feed on fish, crustaceans, mollusks, and plankton.

It contained elements  of Hinduism and Buddhism and was  founded on the millenarian expecta�  tion of a series of disasters that  would bring an end to this world and  inaugurate a new cosmic cycle. In 1995 its members released nerve gas  into the Tokyo subway system, killing 12 people and injuring some 5,500.  The group has been linked with other nerve-gas incidents and violent  crimes. It claimed some 50,000 members, mostly in Russia, at the time  of the gas attack. Membership collapsed in the wake of the attack, but it  had grown to more than 1,500 members by the early 21st century. The  group changed its name to Aleph in 2000. More than 10 AUM members  were sentenced to death for their involvement in the gassing incident,  including Asahara, who in 2004 was found guilty of masterminding the  attack.</p><p>Aung San V6q-'san\ (b. 1914?, Natmauk, Burma�d.

He  accepted Japanese aid in raising a military force in Burma that helped the  Japanese in their 1942 invasion. However, he came to doubt that the Japa�  nese would ever allow Burma to become independent and grew displeased  with their treatment of Burmese forces, and in 1945 he switched to the  Allied cause. After the war, he effectively became prime minister and  negotiated Burma�s independence, which was agreed on in 1947; he was  assassinated before independence was achieved in 1948.</p><p>Aung San Suu Kyi Vorj-'san-'sii-'cheX (b.

She lived quietly in Britain until, returning to Myanmar in  1988, she was moved by the brutality of U Ne Win�s military regime to  begin a nonviolent struggle for democracy and human rights. The 1990  electoral victory of her National League for Democracy was ignored by  Ne Win�s government, and she was held under house arrest from 1989 to  1995. She subsequently continued her opposition activities and was sub�  ject to varying degrees of government harrassment, including another  period of house arrest in 2000-02.

He was the father of all giants;  a male and female grew under his arm and his legs produced a six-headed  son, whom the cow Audumla nursed. Audumla licked salty frost from  stones, which she shaped into the man Buri, grandfather of Odin and his  brothers. The gods killed Aurgelmir and put his body into the void, where  his flesh became the earth, his blood the seas, his bones mountains, his  teeth stones, his skull the sky, and his brains the clouds.

Its tools included scrap�  ers, burins (which made the  engraving possible), and blades.</p><p>Points and awls were fashioned from  bones and antlers. Aurignacian art  represents the first complete artistic  tradition, moving from simple  engravings of animal forms on small  rocks to finer pieces of carved bone  and ivory to highly stylized clay  figurines of pregnant women (the  so-called �Venus figures,� presumably fertility figures). By the end of the  Aurignacian, hundreds of engravings, reliefs, and paintings had been  executed on the walls and ceilings of limestone caves in western Europe,  most famously Lascaux Grotto.</p><p>aurochs \'aur-,aks\ or auroch Extinct wild ox ( Bos primigenius) of  Europe, the species from which cattle are probably descended.

Some  German breeders claim to have re-created this race since 1945, but their  animals are smaller and probably lack the aurochs�s genetic constitution.  The name has sometimes been wrongly applied to the European bison.</p><p>Aurora Roman goddess of dawn. Her Greek counterpart was Eos. Hesiod  described her as the daughter of the Titans Hyperion and Theia. She was  the sister of Helios, the sun, and Selene, the moon.

In Greek  mythology she was also represented as the lover of the hunters Cephalus  and Orion.</p><p>aurora Luminous phenomenon of the upper atmosphere that occurs pri�  marily at high latitudes. Auroras in the Northern Hemisphere are called  aurora borealis, or northern lights; in the Southern Hemisphere they are  called aurora australis, or southern lights. Auroras are caused by the inter�  action of energetic particles (electrons and protons) from outside the atmo�  sphere with atoms of the upper atmosphere. Such interaction occurs in  zones surrounding the Earth�s magnetic poles. During periods of intense  solar activity, auroras occasionally extend to the middle latitudes.</p><p>Aurora City (pop., 2000: 276,393), north-central Colorado, U.S. It was  founded near Denver as Fletcher during the silver boom of 1891 and  renamed in 1907.

It consisted of three camps (prison, extermi�  nation, and forced labour), established in 1940, 1941 (Birkenau), and  1942. Able-bodied Jewish prisoners were sent to a slave-labour camp,  while the aged, the weak, and children and their mothers were killed.  Some prisoners were also subjected to medical experiments, conducted  by Josef Mengele. The camp was gradually abandoned in 1944^45 as  Soviet troops advanced. The total number who died at Auschwitz is esti�  mated at between 1.1 million and 1.5 million, 90% of which were Jews;  also among the dead were some 19,000 Roma (Gypsies), who were killed  in July 1944, and some 83,000 Poles.

He taught at  Oxford from 1945 until his death. He was a leading member of the �ordi�  nary language,� or �Oxford,� movement of analytic philosophy, which was  characterized by its belief that philosophical problems frequently arise  through inattention to or misunderstandings of ordinary uses of language;  accordingly, such problems can be resolved through consideration of the  ordinary uses of the terms by which the relevant philosophical concepts are  expressed. Ordinary-language analyses by Austin and his followers fre�  quently took the form of asking �what one would say� in various concrete  situations. Austin was also the inventor of speech act theory, through which  he attempted to account for the various �performative� aspects of conveyed  linguistic meaning. Several of his essays and lectures were published post�  humously in Philosophical Papers (1961), Sense and Sensibilia (1962),  and How to Do Things with Words (1962). See also analytic philosophy.</p><p>Austin, John (b. March 3, 1790, Creeting Mill, Suffolk, Eng.�d. Dec.  1859, Weybridge, Surrey) British jurist. Although initially unsuccessful  in his law practice (1818-25), his analytical mind and intellectual hon�  esty impressed colleagues, and he was named the first professor of juris�  prudence at University College, London (1826). Distinguished men  attended his lectures, but he failed to attract students, and he resigned his  chair in 1832. His writings, especially The Province of Jurisprudence  Determined (1832), sought to distinguish law from morality. He also  helped to define jurisprudence as the analysis of fundamental legal con�  cepts, as distinct from the criticism of legal institutions, which he called  the �science of legislation.� His work, largely unrecognized in his life�  time, influenced later jurists, including Oliver Wendell Holmes, Jr.</p><p>Austin, Stephen (Fuller) (b.

He  was raised in the Missouri Territory and served in its legislature (1814�  19). The economic panic in 1819 led his father to conceive a plan to colo�  nize Texas on land obtained from the Mexican government. Austin  continued the project after his father died (1821) and founded a colony  of several hundred families on the Brazos River in 1822. He maintained  good relations with the Mexican government. He tried to induce the Mexi�  can government to make Texas a separate state in the Mexican confed�  eration; when this attempt failed, he recommended in 1833 the  organization of a state without waiting for the consent of the Mexican  congress, and he was imprisoned. Released in 1835, he traveled to the  U.S. to secure help when the Texas revolution broke out in October of  that year. He is considered one of the state�s founders. The city of Austin  is named for him.</p><p>Austral Islands Group of islands (pop., 2002: 6,386), southern French  Polynesia. The southernmost part of French Polynesia ( austral is Latin for  �south�), the islands form a chain about 800 mi (1,300 km) long. They  were sighted by Capt. James Cook in 1769 and 1777.

Area: 2,969,978 sq mi (7,692,208 sq km).  Population (2005 est.): 20,345,000. Capital: Canberra. Most Australians  are descendants of Europeans. The largest nonwhite minority is the Aus�</p><p>tralian Aborigine population. The Asian portion of the population has  grown as a result of relaxed immigration policy. Language: English (offi�  cial). Religions: Christianity (mostly Protestant; also Roman Catholic,  Eastern Orthodox, other Christians), Buddhism, Islam. Currency: Austra�  lian dollar. Australia has three major physiographic regions. More than  half of its land area is on the Western Australian plateau, which includes  the outcrops of Arnhem Land and the Kimberleys in the northwest and the  Macdonnell Ranges in the east. A second region, the Interior Lowlands,  lies east of the plateau. The Eastern Uplands, which include the Great  Dividing Range, are a series of high ridges, plateaus, and basins. The coun�  try�s highest point is Mount Kosciusko in the Australian Alps, and the low�  est is Lake Eyre. Major rivers include the Murray-Darling system, the  Funders and Swan rivers, and Cooper Creek. There are many islands and  reefs along the coast, including the Great Barrier Reef, Melville Island, Kan�  garoo Island, and Tasmania. Australia is rich in mineral resources, includ�  ing coal, petroleum, and uranium. A vast diamond deposit was found in  Western Austraua in 1979. The country�s economy is basically free enter�  prise; its largest components include finance, manufacturing, and trade.  Formally a constitutional monarchy, its chief of state is the British mon�  arch, represented by the governor-general. In reality it is a parliamentary  state with two legislative houses; its head of government is the prime min�  ister. Australia has long been inhabited by Aborigines, who began arriving  at least 50,000 years ago. Estimates of the population at the time of Euro�  pean settlement in 1788 range from 300,000 to 1,000,000. Widespread  European knowledge of Australia began with 17th-century explorations.  The Dutch landed in 1616 and the British in 1688, but the first large-scale  expedition was that of James Cook in 1770, which established Britain�s  claim to Australia. The first British settlement, at Port Jackson (1788),  consisted mainly of convicts and seamen; convicts were to make up a large  proportion of the incoming settlers. By 1859 the colonial nuclei of all Aus�  tralia�s states had been formed, but with devastating effects on the indig�  enous peoples, whose populations declined sharply with the introduction  of European diseases. Britain granted its colonies limited self-government  in the mid-19th century, and an act federating the colonies into a common�  wealth went into effect in 1901. Australia fought alongside the British in  World War I, notably at Gallipoli, and again in World War II, preventing  Australia�s occupation by the Japanese. It joined the U.S. in the Korean  and Vietnam wars. Since the 1960s the government has sought to deal more  fairly with the Aborigines, and a loosening of immigration restrictions has  led to a more heterogeneous population. Constitutional links allowing  British interference in government were formally abolished in 1968, and  Australia has assumed a major role in Asian and Pacific affairs. During the  1990s there were several debates about giving up its British ties and  becoming a republic.

More than  half are now extinct; of the remainder, only about 20, mostly in the North  Territory and northern Western Australia, remain in active use by both  adults and children. Most Australian languages belong to a single super�  family, Pama-Nyungan, and the remainder, a very diverse group of lan�  guages spoken in the Kimberley region of Western Australia and parts of  the North Territory, may be remotely akin to Pama-Nyungan.</p><p>Australian Aborigine \a-b3- , ri-jo- l ne\ Any of the indigenous peoples  of Australia. The first Australians are estimated to have reached the con�  tinent at least 50,000 years ago. At one time there may have been as many  as 500 language-named, territorially anchored groups of indigenous Aus�  tralians. They subsisted as hunters and gatherers. Groups (bands) were  formed along the male line (patrilineal descent) and consisted of two or  more families. Their lives were centred around a specific site settled by  the group�s ancestors. The men were custodians of the mythology, ritual,  sites, and symbols evoked in the Dreaming. Australian Aborigines are  believed to have numbered 300,000-1,000,000 when European coloniza�  tion began in the late 18th century, but they were devastated by intro�  duced diseases and by the bloody 19th-century policy of �pacification by  force.� In the early 21st century they were estimated to number more than  400,000.

Religion involved living in agreement with the way of life  ordained in the Dreaming, through the performance of rituals and obedi�  ence to the law. Through dreams and other states of altered conscious�</p><p>ness, the living could come into contact with the spiritual realm and gain  strength from it; myths, dances, and other rituals bound the human, spiri�  tual, and physical worlds together in a single cosmic order. A child�s spirit  was held to come from the dreaming to animate a fetus, and a person�s  spiritual heritage was more important than the bond between a physical  parent and child. Sacred art included tjurunga, sand and cave paintings,  and paintings on bark.</p><p>Australian Rules football Variety of football played between two  teams of 18 players. The field is oval, 148-202 yd (135-185 m) long,  with four goalposts at each end. A six-point goal is scored when the oval  ball is kicked through the two central goalposts. A one-point �behind� is  scored when the ball is kicked over the behind line extending between the  central and outer goalposts. The game�s finest spectacle is the �mark� in  which competing players leap, sometimes riding on the back of an oppo�  nent, in order to catch the ball directly from the kick of another player.  The player making such a catch is awarded a mark, an unhindered kick  from behind the spot of the catch. The sport, Australia�s foremost, was  developed in Melbourne. The Victorian Football League was established  in 1896 as the first professional league. It was renamed the Australian  Football League in 1990 to reflect the addition of franchises outside of  Victoria state.</p><p>Australopithecus Vo-.stra-lo-'pi-tha-kssV Latin "southern ape"</p><p>Genus of extinct hominins that may be ancestral to human beings ( Homo  sapiens). The name Australopithecus refers to the first fossils, which were  discovered in South Africa. Australopithecus lived in much of Africa dur�  ing the Pliocene Epoch (c. 5.3-1.8 million years ago [mya]). These hom�  inins were distinguished from apes by their upright posture and bipedal</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Austrasia &#x25BA; Austro-German Alliance I 135</p><p>gait, and their teeth were more  humanlike than apelike, but their  brains were small and not very dif�  ferent from those of living apes. Five  species are recognized: A. anamen-  sis (4.2-3.9 mya), A. afarensis (3.8-  2.9 mya), A. bahrelghazali (3.5-3.0  mya), A. africanus (3-2.4 mya), and  A. garhi (2.5 mya). Three �robust�  species are now instead classified as  Paranthropus (2.7-1.3 mya): P.  aethiopicus, P. robustus, and P. boi-  sei.

During the Merovingian dynasty (6th-8th centuries  ad), it was the eastern Frankish kingdom and Neustria was the western  kingdom. Austrasia covered present-day northeastern France and areas of  western and central Germany; its capital was at Metz. The region was the  power base of the early Carolingian mayors of the palace, one of whom,  Pippin III, deposed the last Merovingian king in 751 and founded the Car�  olingian dynasty. The dynasty�s heartland, Austrasia, was an important  region in the empire established by Charlemagne.</p><p>Austria officially Republic of Austria Country, south-central  Europe.

Religions:</p><p>Christianity (predominantly Roman Cath�  olic; also Protestant); also Islam. Cur�  rency: euro. Much of Austria is covered by  Alpine regions, including the eastern Alps,</p><p>where the country�s highest point, the Grossglockner, is found. The Bohe�  mian Forest, a highland region, extends north into the Czech Republic.  The lowland region, including the Vienna Basin, lies in the east; it sup�  ports mainly agricultural activities. The Danube River and its tributaries  drain nearly the entire country. Austria has a developed mixed free-market  and government-operated economy based on manufacture and commerce;  tourism is also important. Austria is a republic with two legislative houses.  The chief of state is the president, and the head of government is the  chancellor. Austria�s greatest cultural contribution has been in music (see  Joseph Haydn; Wolfgang Amadeus Mozart; Franz Schubert; Alban Berg;</p><p>Anton Webern). Major cultural figures in other fields include Oskar Koko�  schka in art, Sigmund Freud in psychoanalysis, and Ludwig Wittgenstein in  philosophy. Settlement in Austria goes back some 3,000 years, when Illyr�  ians were probably the main inhabitants. The Celts invaded c. 400 bc and  established the kingdom of Noricum. The Romans arrived after 200 bc  and established the provinces of Raetia, Noricum, and Pannonia; prosper�  ity followed, and the population became Romanized. With the fall of  Rome in the 5th century ad, many tribes invaded, including the Slavs;  they were eventually subdued by Charlemagne, and the area became eth�  nically Germanic. The distinct political entity that would become Austria  emerged in 976 with Leopold I of Babenberg as margrave. In 1278 Rudolf  IV of Habsburg (later Rudolf I as the king of Germany) conquered the area;  Habsburg rule lasted until 1918. While in power, the Habsburgs created  a kingdom centred on Austria, Bohemia, and Hungary. The Napoleonic  Wars brought about the end of the Holy Roman Empire (1806) and the  emergence of the Austrian Empire. The prince von Metternich tried to  assure Austrian supremacy among Germanic states, but war with Prussia  led Austria to divide the empire into the Dual Monarchy of Austria-  Hungary. Nationalist sentiment plagued the kingdom, and the assassina�  tion of Francis Ferdinand by a Bosnian Serb nationalist in 1914 triggered  World War I, which destroyed the Austro-Hungarian Empire. In the post�  war carving up of Austria-Hungary, Austria became an independent repub�  lic. It was annexed by Nazi Germany in 1938 (see Anschluss) and joined  the Axis powers in World War II. The republic was restored in 1955 after  10 years of Allied occupation. Austria became a full member of the Euro�  pean Union (EU) in 1995. After a half-century of military neutrality, Aus�  tria was one of the few members of the EU that was not a member of  NATO at the outset of the 21st century.</p><p>Austria-Hungary or Austro-Hungarian Empire Former mon�  archy, central Europe. Austria-Hungary at one time included Austria and  Hungary, Bohemia, Moravia, Bukovina, Transylvania, Camiola, Ktisten-  land, Dalmatia, Croatia, Fiume, and Galicia. The so-called Dual Monar�  chy, formed by the Compromise of 1867, created a king of Hungary in  addition to the existing Austrian emperor; though these were the same  person, Hungary was granted its own parliament and considerable  autonomy. Francis Joseph held both titles from Austria-Hungary�s incep�  tion until his death in 1916. Up to 1914, the monarchy maintained a pre�  carious balance among its many minorities; that year saw the balance  toppled with the assassination of the Austro-Hungarian Francis Ferdinand  by a Serbian nationalist that precipitated World War I. With its defeat in  that war and revolutions by the Czechs, Yugoslavs, and Hungarians, the  monarchy collapsed in 1918.</p><p>Austrian Netherlands (1713-95) Provinces located in the southern  part of the Low Countries, roughly comprising modern Belgium and Lux�  embourg. In 1713, the Peace of Utrecht gave Emperor Charles VI control  of what had been called the Spanish Netherlands. Administration of the  region continued under the Habsburg rulers Maria Theresa and later Joseph  II. until the Austrian Netherlands was annexed to France in 1795.</p><p>Austrian school of economics Body of economic theory developed  by several late 19th-century Austrian economists. Carl Menger (1840-  1921) published a paper on their new theory of value in 1871. The con�  cept of value was subjective, the source of a product�s value being its  ability to satisfy human wants. The actual value depended on the utility  derived by the consumer from the product in its least important use (mar�  ginal utility). The theory was also applied to production and pricing. Other  founders of the school included Friedrich von Wieser (1851-1926) and  Eugen von Bohm-Bawerk (1851-1914). See also opportunity cost; pro�  ductivity.</p><p>Austrian Succession, War of the (1740^-8) Group of related wars  that took place after the death (1740) of Emperor Charles VI. At issue was  the right of Charles�s daughter Maria Theresa to inherit the Habsburg lands.  The war began when Frederick II of Prussia invaded Silesia in 1740. His  victory suggested that the Habsburg dominions were incapable of defend�  ing themselves, prompting other countries to enter the fray. The conflict  was ended by the Treaty of Aix-la-Chapelle.</p><p>Austro-German Alliance or Dual Alliance (1879) Pact between  Austria-Hungary and the German Reich in which the two powers prom�  ised each other support in case of attack by Russia, and neutrality in case  of aggression by any other power.

Today most scholars believe that it is sub�  divided into two families, Munda and Mon-Khmer. The present fragmented  distribution of Austroasiatic languages is most likely the result of rela�  tively recent incursions by Indo-Aryan, Sino-Tibetan, Tai, and  AusTRONESiAN-speaking peoples. In prehistoric times Austroasiatic lan�  guages most likely extended over a much broader and more continuous  area, including much of what is now southeastern China. Other than Viet�  namese and Khmer, no Austroasiatic language is an official national lan�  guage.</p><p>Austronesian languages formerly Malayo-Polynesian lan�  guages Family of about 1,200 languages spoken by more than 200 mil�  lion people in Indonesia, the Philippines, Madagascar, the central and  southern Pacific island groups (except most of New Guinea; see Papuan  languages), and parts of mainland Southeast Asia and Taiwan. Before  European colonial expansion, it had the widest territorial extent of any lan�  guage family. A primary genetic division in the family separates the Aus�  tronesian languages of Taiwan from the remaining languages, which are  divided into Western and Central-Eastern Malayo-Polynesian. Western  Malayo-Polynesian includes Javanese, which is spoken by about 76 mil�  lion people�more than a third of all Austronesian-speakers. Eastern  Malayo-Polynesian includes Oceanic, the best-defined subgroup of Aus�  tronesian, comprising nearly all the languages of Polynesia, Micronesia, and  Melanesia. Typological generalizations about Austronesian languages are  difficult because of their enormous number and diversity, though content  words tend to be disyllabic, and vowel and consonant inventories tend to be  limited, especially in Polynesian. Written records in scripts of Southeast  Asian provenance (see Indic writing system) survive for several languages,  including Old Javanese and Cham, the language of the kingdom of Champa.</p><p>auteur \o-'toer\ theory Theory that holds that a film�s director is its  �author� (French, auteur). It originated in France in the 1950s and was  promoted by Francois Truffaut and Jean- Luc Godard and the journal Cah-  iers du Cinema. The director oversees and �writes� the film�s audio and  visual scenario and therefore is considered more responsible for its con�  tent than the screenwriter. Supporters maintain that the most successful  films bear the distinctive imprint of their director.</p><p>authoritarianism Principle of unqualified submission to authority, as  opposed to individual freedom of thought and action. As a political sys�  tem, authoritarianism is antidemocratic in that political power is concen�  trated in a leader or small elite not constitutionally responsible to those  governed. It differs from totalitarianism in that authoritarian governments  usually lack a guiding ideology, tolerate some pluralism in social orga�  nization, lack the power to mobilize the whole population in pursuit of  national goals, and exercise their power within relatively predictable lim�  its. See also absolutism, dictatorship.</p><p>autism Neurobiological disorder that affects physical, social, and lan�  guage skills. First described by Leo Kanner and Hans Asperger in the  1940s, the syndrome usually appears before IVi years of age. Autistic  infants appear indifferent or averse to affection and physical contact. They  may be slow in learning to speak and suffer episodes of rage or panic;  they may also appear deaf and display an almost hypnotized fascination  with certain objects. Autism is often characterized by rhythmic body  movements such as rocking or hand-clapping and by an obsessive desire  to prevent change in daily routines. Autistic individuals may be hyper�  sensitive to some stimuli (e.g., high-pitched sounds) and abnormally slow  to react to others (e.g., physical pain). The disorder is three to four times  more common in males. Though postnatal factors such as lack of paren�  tal attention were once blamed, it is now known that autism is the result  of abnormalities in the brain structure. About 15-20% of autistic adults  live and work independently; �high-functioning� autistic people may have  special abilities based on their unusual ability for visual thinking.

Little auto�  biographical literature exists from antiquity and the Middle Ages; with a  handful of exceptions, the form begins to appear only in the 15th century.  Autobiographical works take many forms, from intimate writings made  during life that are not necessarily intended for publication (including let�  ters, diaries, journals, memoirs, and reminiscences) to the formal autobi�  ography. Outstanding examples of the genre extend from St. Augustine�s  Confessions (c. ad 400) to Vladimir Nabokov�s Speak, Memory (1951).</p><p>autoclave Vessel, usually of steel, able to withstand high temperatures  and pressures. The chemical industry uses various types of autoclaves in  manufacturing dyes and in other chemical reactions requiring high pres�  sures. In bacteriology and medicine, instruments, equipment, supplies,  and culture media are sterilized by superheated steam in an autoclave. In  1679 Denis Papin (1647-c. 1712) invented a prototype known as a steam  digester; still used in cooking, it is now called a pressure cooker.</p><p>autograph Any manuscript handwritten by its author; in common  usage, a handwritten signature. Aside from its value as a collector�s item,  an early or corrected draft of a work may show its stages of composition  or �correct� final version. The earliest autograph signature of a famous  person is probably the Cid�s, dated 1096. There exist autographs of most  of the great Renaissance figures, including Leonardo da Vinci, Michelan�  gelo, and Ludovico Ariosto. Since the 1 8th century, autograph material of  notable people in the arts, sciences, or public life has been more abundant.</p><p>autoimmune disease Any disease caused by an immune response  (see immunity) against antigens in the tissues of one�s own body. The immune  system has two known ways to prevent such a response: destruction of  lymphocytes in the thymus before they leave to attack one�s own tissues and  loss of ability to react to their target antigens by any such cells that do  leave the thymus. Autoimmune diseases arise when these mechanisms fail  and lymphocytes destroy host tissues; examples include type 1 diabetes  mellitus, systemic lupus erythematosus, pernicious anemia, and rheumatoid  arthritis. Treatment may replace the function of the affected tissue (e.g.,  insulin therapy for diabetes) or suppress the immune system (see immun�  osuppression). Allergy is another type of autoimmune reaction.</p><p>automata fo-'ta-mo-toX theory Body of physical and logical prin�  ciples underlying the operation of any electromechanical device (an  automaton) that converts information input in one form into another, or  into some action, according to an algorithm. Norbert Wiener and Alan M.  Turing are regarded as pioneers in the field. In computer science, automata  theory is concerned with the construction of robots (see robotics) from  basic building blocks of automatons. The best example of a general  automaton is an electronic digital computer. Networks of automata may be  designed to mimic human behaviour. See also artificial intelligence; Turing  MACHINE.</p><p>automation Term coined about 1946 by a Ford Motor Co. engineer,  used to describe a wide variety of systems in which there is a significant  substitution of mechanical, electrical, or computerized action for human  effort and intelligence. In general usage, automation can be defined as a  technology concerned with performing a process by means of pro�  grammed commands combined with automatic feedback control (see con�  trol system) to ensure proper execution of the instructions. The resulting  system is capable of operating without human intervention.</p><p>automatism Xo-'ta-mo-.tiz-omX Method of painting or drawing in  which conscious control over the movement of the hand is suppressed so  that the subconscious mind may take over. For some Abstract Expression�  ists, such as Jackson Pollock, the automatic process encompassed the  entire process of composition.

Except for some works by  Carl Faberge, the production of expensive automatons virtually ceased by  the 20th century.</p><p>automobile Four-wheeled automotive vehicle designed for passenger  transportation, commonly propelled by an internal combustion engine using  a volatile fuel. The modem automobile consists of about 14,000 parts,  divided into several structural and mechanical systems. These include the  steel body, containing the passenger and storage space, which sits on the  chassis or steel frame; the internal combustion gasoline engine, which  powers the car by means of a transmission; the steering and braking sys�  tems, which control the car�s motion; and the electrical system, which  includes a battery, alternator, and other devices. Subsystems involve fuel,  exhaust, lubrication, cooling, suspension, and tires. Though experimental  vehicles were built in the 18th and mid-19th century, not until the 1880s  did Gottlieb Daimler and Karl Benz in Germany begin separately to manu�  facture cars commercially. In the U.S., James and William Packard and  Ransom Olds were among the first auto manufacturers, and by 1898 there  were 50 U.S. manufacturers. Some early cars operated by steam engine,  such as those made from c. 1902 by Francis E. and Freelan O. Stanley. The  internal combustion engine was used by Henry Ford when he introduced  the Model T in 1908; Ford would soon revolutionize the industry with his  use of the assembly line. In the 1930s European manufacturers began to  make small, affordable cars such as the Volkswagen. In the 1950s and  �60s, U.S. automakers produced larger, more luxurious cars with more  automatic features. In the 1970s and �80s Japanese manufacturers  exported their small, reliable, fuel-efficient cars worldwide, and their  increasing popularity spurred U.S. automakers to produce similar models.

It includes the sympathetic, parasympathetic, and enteric nervous  systems. The first, which connects the internal organs to the brain via spi�  nal nerves, responds to stress by increasing heart rate and blood flow to  the muscles and decreasing blood flow to the skin. The second comprises  the cranial nerves and the lower spinal nerves, which increase digestive  secretions and slow the heartbeat. Both have sensory fibres that send  feedback on the condition of internal organs to the central nervous sys�  tem, information that helps maintain homeostasis. The third division,  embedded in the walls of the stomach and intestines, controls digestive  movement and secretions. See illustration opposite.</p><p>autopsy \'6-,tap-se\ or necropsy or postmortem Dissection and  examination of a dead body to determine cause of death and learn about  disease processes in ways that are not possible with the living. Autopsies  have contributed to the development of medicine since at least the Middle  Ages. Beyond revealing causes of individual deaths, autopsy is crucial to  the accuracy of disease and death statistics, the education of medical stu�  dents, the understanding of new and changing diseases, and the advance�  ment of medical science.</p><p>Autry, (Orvon) Gene (b.

Aviaries range from small enclosures to large  flight cages 100 ft (30 m) or more long and up to 50 ft (15 m) high.  Enclosures for birds that fly only little or weakly (e.g., rails, pheasants)  may be only about 3 ft (1 m) high. In cold climates the aviary is usually  enclosed and heated. Most aviculturists prefer to place birds in natural,  planted surroundings. Many aviaries are maintained for pleasure by pri�  vate aviculturists; others, especially large ones, are found in zoos or  research institutions.</p><p>aviation Development and operation of aircraft. In 1783 the balloon  became the first aircraft to carry humans. Production of a successful glider  in 1891 and refinement of the internal-combustion engine led to the first  successful engine-powered airplane flight by Wilbur and Orville Wright in  1903. World War I accelerated the expansion of aviation, and in the 1920s  the first small airlines began carrying mail and passengers. World War II  was another period of innovation in aircraft size, speed, and range. In the  late 1940s the jet engine made possible the subsequent development of  commercial airlines throughout the world.

Founded by the Gallic tribe of Cavares, it  later fell under Roman rule and was a much-fought-over prize in its early  days. Its status grew tremendously as the capital of the papacy (1309-77)  and seat of the Avignonese popes during the Western Schism. France  annexed the city in 1791. Landmarks include a Romanesque cathedral,  the papal palace, and Saint-Benezet bridge, made famous by the song �Sur  le pont d�Avignon.� The city�s historic centre was designated a World  Heritage site in 1995.</p><p>Avignon papacy Roman Catholic papacy during the period 1309-77,  when the popes resided at Avignon, France. Elected pope through the  machinations of Philip IV of France, Clement V moved the papal capital  to Avignon four years later primarily for political reasons. All seven popes  of this period were French, as were most of the cardinals, which aroused  English and German animosity. During the Avignon papacy the cardinals  began to play a stronger role in church government, church and clergy  were reformed, missionary efforts were expanded, and popes tried to settle  royal rivalries and establish peace. The heavy French influence damaged  the prestige of the papacy, however, and in 1377 Gregory XI returned to  Rome. The cardinals elected a new pope who took the Avignon seat,  becoming the first of a line of antipopes and beginning the Western Schism.</p><p>Avignon school School of late Gothic painting associated with the city  of Avignon, Fr., during the Avignon papacy, when many Italian artists  worked there. This �school� represents a body of late Gothic painting and  not necessarily a single stylistic evolution. Under the direction of Simone  Martini, the papal palace of Avignon and secular buildings in nearby towns  were decorated with frescoes. The city was one of the channels by which  Italian 14th-century art reached France. By the early 15th century Flem�  ish influences had reached the city, consolidating the Italian and northern  styles. The Avignon Pieta (c. 1460), attributed to Enguerrand Charonton,</p><p>is the masterpiece of the school.

Stone  Age hand axes originated in simple stone implements that acquired  wooden hafts, or handles, about 30,000 bc. Copper-bladed axes appeared  in Egypt about 4000 bc and were followed by axes with blades of bronze  and eventually iron. The development of the iron-bladed felling ax in the  Middle Ages made possible the vast forest clearances of Europe, North  and South America, and elsewhere. Though the ax has lost much of its  historic role to powered saws and other machinery, it remains a widely  used tool with many uses.</p><p>axiology or value theory Philosophical theory of value. Axiology  is the study of value, or goodness, in its widest sense. The distinction is  commonly made between intrinsic and extrinsic value�i.e., between that  which is valuable for its own sake and that which is valuable only as a  means to something else, which itself may be extrinsically or intrinsically  valuable. Many different answers have been given to the question �What  is intrinsically valuable?� For hedonists, it is pleasure; for pragmatists, it  is satisfaction, growth, or adjustment; for Kantians, it is a good will. Plu-  ralists such as G.E. Moore and William David Ross assert that there are any  number of intrinsically valuable things. According to subjective theories  of value, things are valuable only insofar as they are desired; objective  theories hold that there are at least some things that are valuable inde�  pendently of people�s interest in or desire for them. Cognitive theories of  value assert that ascriptions of value function logically as statements of  fact, whereas noncognitive theories assert that they are merely expres�  sions of feeling (see emotivism) or prescriptions or commendations (see  prescriptivism). According to naturalists, expressions such as �intrinsically  good� can be analyzed as referring to natural, or non-ethical, properties,  such as being pleasant. Moore famously denied this, holding that �good�  refers to a simple (unanalyzable) non-natural property. See also fact-value  distinction; naturalistic fallacy.</p><p>axiom In mathematics or logic, an unprovable rule or first principle  accepted as true because it is self-evident or particularly useful (e.g.,  �Nothing can both be and not be at the same time and in the same  respect�). The term is often used interchangeably with postulate, though  the latter term is sometimes reserved for mathematical applications (such  as the postulates of Euclidean geometry). It should be contrasted with a  theorem, which requires a rigorous proof.</p><p>axiomatic method In logic, the procedure by which an entire science  or system of theorems is deduced in accordance with specified rules by  logical deduction from certain basic propositions (axioms), which in turn  are constructed from a few terms taken as primitive. These terms may be  either arbitrarily defined or conceived according to a model in which some  intuitive warrant for their truth is felt to exist. The oldest examples of  axiomatized systems are Aristotle�s syllogistic and Euclidean geometry.  Early in the 20th century, Bertrand Russell and Alfred North Whitehead  attempted to formalize all of mathematics in an axiomatic manner. Schol�  ars have even subjected the empirical sciences to this method, as in J. H.  Woodger�s The Axiomatic Method in Biology (1937) and Clark Hull�s  Principles of Behavior (1943).</p><p>Axis Powers Coalition headed by Germany, Italy, and Japan that  opposed the Allied Powers in World War II. The alliance originated in a</p><p>series of agreements between Germany and Italy, followed in 1936 by the  Rome-Berlin Axis declaration and the German-Japanese Anti-Comintern  Pact. The connection was strengthened by the formal Pact of Steel (1939)  between Germany and Italy and by the Tripartite Pact signed by all three  powers in 1940. Several other countries, including Hungary, Romania,  Bulgaria, Croatia, and Slovakia, later allied themselves with the original  Axis Powers.</p><p>axle Pin or shaft on or with which wheels revolve; with fixed wheels,  one of the basic simple machines for amplifying force. Combined with the  wheel, in its earliest form it was probably used for raising weights or water  buckets from wells. Its principle of operation can be illustrated in the  attachment of large and small gears to the same shaft; the tendency of a  force applied at the radius on the large gear to turn the shaft is sufficient  to overcome a larger force at the radius on the small gear. The mechanical  advantage is equal to the ratio of the two forces and also equal to the ratio  of the radii of the two gears.</p><p>Axminster carpet Floor covering produced in a factory founded at  Axminster, England, in 1755 by the cloth weaver Thomas Whitty.

In the  16th century the Mughal emperor Babur built a mosque on a site tradi�  tionally associated with an ancient Hindu temple marking the birthplace  of the god Rama. The storming of the mosque by Hindus in 1990, amid  religious tensions, was followed by riots, and the ensuing crisis brought  down the government. In 1992 the mosque was demolished by Hindu  fundamentalists, and hundreds of people died in the rioting that subse�  quently swept through India.</p><p>Ayrshire \'er-,shir\ Breed of hardy dairy cattle (see dairy farming) that  originated in the county of Ayr, Scotland, in the late 18th century.

Exported widely to other countries, it is especially common  in Great Britain, the U.S., and Canada.</p><p>Ayub Khan \a-'ub-'kan\, Mohammad (b. May 14, 1907, Hazara,  India�d. April 19, 1974, near Islamabad, Pak.) President of Pakistan  (1958-69). After studies at Aligarh Muslim University and at the British  Royal Military College, he became an officer in the Indian army (1928).  He fought in Burma (Myanmar) in World War II, and afterward he rose  through the ranks in the military in newly independent Pakistan. In 1958  Pakistan�s Pres. Iskander Mirza abrogated the country�s constitution, and  Ayub became chief martial-law administrator. He declared himself presi�  dent the same year, exiling Mirza. He established close ties with China  and in 1965 went to war with India over control of the Kashmir region.  The failure to take Kashmir, combined with unrest over suffrage restric�  tions, led to riots, and Ayub resigned in 1969.</p><p>Ayurveda Va-yor-.va-doV or Ayurvedic medicine Traditional sys�  tem of Indian medicine. It is attributed to Dhanvantari, the physician to  the gods in Hindu mythology, who received it from Brahma. Its earliest  concepts were set out in the portion of the Vedas known as the Athar-  vaveda (c. 2nd millennium bc). The most important Ayurvedic texts are  the Caraka samhita and Susruta samhita (1st�4th century ad). These texts  analyze the human body in terms of earth, water, fire, air, and ether as  well as the three bodily humours (wind, bile, and phlegm). To prevent  illness, Ayurvedic medicine emphasizes hygiene, exercise, herbal prepa�  rations, and yoga. To cure ailments, it relies on herbal medicines, phys�</p><p>iotherapy, and diet. Ayurvedic medicine is still a popular form of health  care in India, where it is taught in roughly 100 colleges, and it has gained  currency in the West as a form of alternative medicine.</p><p>Ayutthaya \,a-yu-'tI-9\ in full Phra Nakhon Si Ayutthaya. Town  (pop., 2000 prelim.: 75,898), former capital city of the Thai kingdom of  Ayutthaya. It is located northeast of present-day Bangkok. Modern-day  Thailand (then called Siam) is said to date from its founding (between  1347 and 1351). The kingdom of Ayutthaya was once one of the most  powerful in Southeast Asia, and its capital city flourished for more than  400 years. Much of the ancient city�s architecture, art, and literature was  destroyed in 1767 when it was sacked by Hsinbyushin of the Alaungpaya  dynasty. The modern town of Ayutthaya is set among the ruins of the  ancient city. There is some manufacturing, and tourism is important. The  area was designated a UNESCO World Heritage site in 1991.</p><p>Ayyubid \a-'yu-bid\ dynasty (1173-1250) Kurdish dynasty founded  by Saladin that ruled over Egypt, most of Syria, upper Iraq, and Yemen.  After overthrowing the Fajimid dynasty, Saladin defended Palestine during  the Crusades and made Egypt the most powerful Muslim state in the world.  After Saladin�s death the Ayyubid regime became decentralized. In 1250  a group of mamluks (military slaves) exploited a lapse in Ayyubid suc�  cession to take over the government in Egypt and to found the MamlOk  dynasty. Minor Ayyubid princes continued to rule in parts of the Syria for  some years afterward.</p><p>azalea Any plant of certain species of the genus Rhododendron (heath  family), formerly given the generic name Azalea. Though some gardeners  consider azaleas distinct from rhododendrons, distinguishing characteris�  tics of the two groups are not consistent enough to separate them into two  genera. Azaleas typically are deciduous (see deciduous tree), with flowers  that are funnel-shaped, somewhat two-lipped, and often fragrant. Culti�  vated varieties have been bred from species native to the hilly regions of  Asia and North America. Well-known North American kinds include the  smooth, or sweet, azalea ( R. arborescensf, the flame azalea (R. calen-  dulaceum ); and the pinxter flower (R. periclymenoides ).</p><p>Azall \a-za-'le\ Any member of the Bab! movement who remained faith�  ful to the teachings of the Bab and his chosen successor, Mirza Yahya,  known as Sobh-e Azal, after the movement split in 1863. For 13 years  after the Bab�s execution, followers recognized Sobh-e Azal as their  leader. Then Sobh-e Azal�s half-brother, Baha� Ullah, privately declared  himself to be the prophet whose coming the Bab had foretold. The Aza-  lls rejected him, but most Babls followed him, establishing the BahaI faith  in 1867. Now located almost exclusively in Iran, the Azalls probably  number no more than a few thousand.</p><p>Azana \3-'than-yo\ (y Diaz), Manuel (b. Jan. 10, 1880, Alcala de  Henares, Spain�&lt;1.

Elected president in May  1936, he was able to accomplish little before the Spanish Civil War broke  out in July. He lost control of policy and remained in office as only a fig�  urehead until 1939, when he went into exile following the victory of the  Nationalist forces of Francisco Franco.</p><p>Azande See Zande</p><p>Azerbaijan \,a-z9r-bl-'jan\ officially Republic of Azerbaijan</p><p>Country, Transcaucasia, western Asia. Area: 33,400 sq mi (86,600 sq km).  Population (2005 est.): 8,381,000. Capital: Baku. Most residents are of  Turkic origin, dating from the 11th century ad. Later migrations during  the SeuOq period brought further groups, including some speaking Per�  sian; Russians are a decreasing minority. Languages: Azerbaijanian (offi�  cial), Russian. Religion: Islam (mostly Shl'ite). Currency: manat.  Azerbaijan is characterized by a variety of landscapes. More than two-  fifths of its territory is lowlands, while areas above 5,000 ft (1,500 m)  occupy some one-tenth of the total area. The central part of the country  is a plain through which flows the Kura River and its tributaries, includ�  ing the Aras, whose upper course forms part of the boundary with Iran.  The Caspian Sea serves Baku as a trade outlet. Agriculture, petroleum  refining, and light manufacturing are economically important. Azerbaijan  is a republic with one legislative body; its head of state and government  is the president, assisted by the prime minister. Azerbaijan adjoins the Ira�  nian region of the same name, and the origin of their respective inhabit�  ants is the same.

Russia acquired what  is now independent Azerbaijan in the early  19th century. After the Russian Revolution  of 1917, Azerbaijan declared its indepen�  dence; it was subdued by the Red Army in  1920 and was incorporated into the Soviet Union. It declared indepen�  dence from the collapsing Soviet Union in 1991. Azerbaijan has two geo�  graphic peculiarities. The exclave Naxgivan (Nakhichevan) is separated  from the rest of Azerbaijan by Armenian territory. Nagorno-Karabakh,  which lies within Azerbaijan and is administered by it, has a Christian  Armenian majority. Azerbaijan and Armenia went to war over both ter�  ritories in the 1990s, causing many deaths and great economic disruption.  Though attempts at mediation were made, the political situation remained  unresolved.</p><p>Azhar \'az-,har\ University, al- Chief school of Islamic and Arabic  learning in the world, centred on the al-Azhar Mosque in the medieval  quarter of Cairo. It was founded by the Fatimid dynasty in 970. The basic  program has always focused on Islamic law, theology, and the Arabic lan�  guage. Philosophy and medical studies were added during the Middle  Ages but were eventually dropped from the curriculum. Philosophy was  restored at the end of the 19th century, and social sciences were added at  a branch campus in the early 1960s. Women were first admitted in 1962.</p><p>Azikiwe \o-'zik-wa\, Nnamdi (b. Nov. 16, 1904, Zungeru,  Nigeria�d. May 11, 1996, Enugu) First president (1963-66) of indepen�  dent Nigeria. Azikiwe�s National Council party won the important 1959  federal elections and helped stimulate Nigerian independence. In the con�  flict over Biafra (1967-70), Azikiwe first backed his fellow Igbo but then  threw his support to the federal government.

More than half the dyes in commercial use are azo dyes. They  are usually classed according to the fibres for which they are useful or the  methods by which they are applied; direct dyes are absorbed from solu�  tion by the fibres, but others require a second solution (a mordant) or a  second step before the colour is fast.</p><p>Azores \o-'zorz\ Portuguese Acores \9-'so-rish\ Archipelago (pop.,  2001: 242,073), northern Atlantic Ocean, constituting an autonomous  region of Portugal. Its islands are Flores, Corvo, Terceira, Sao Jorge, Pico,</p><p>Faial, Graciosa, Sao Miguel, and Santa Maria; the capital is Ponta Del-  gada (on Sao Miguel). It covers an area of 901 sq mi (2,333 sq km). Sub�  ject to earthquakes and volcanic eruptions, the islands lie some 1,000 mi  (1,600 km) west of mainland Europe. The uninhabited Azores were reput�  edly discovered c. 1427 by Portuguese pilot Diogo de Sevilha. Settlement  began c. 1432; by the end of the 15th century, all the islands were inhab�  ited and trade with Portugal was well established. They were subject to  Spain in 1580-1640, and a famous sea battle between the British and  Spanish occurred off Flores in 1591. The Portuguese installed a governor  and captain general for the whole group in 1766; the islands were given  limited autonomy in 1895. Important air and naval bases were set up there  during World War II; in 1951 the U.S. established a NATO base on Lajes.</p><p>Azov \3-'zof, 'a-.zoA, Sea of Inland sea in Europe between Ukraine  and Russia. It is connected to the Black Sea by Kerch Strait. About 210  mi (340 km) long and 85 mi (135 km) wide, it occupies an area of 14,500  sq mi (37,600 sq km). With a maximum depth of only about 46 ft (14 m),  it is the world�s shallowest sea. It is fed by the Don and Kuban rivers, and  at their entrance in the Taganrog Gulf, its depth is 3 ft (1 m) or less. In  the west lies the Arabat Spit, a 70-mi- (113-km-) long sandbar that sepa�  rates the Sea of Azov from the Sy vash, a system of marshy inlets divid�  ing the Crimean Peninsula from the Ukrainian mainland.</p><p>AZT in full azidothymidine also known as zidovudine Drug that  has had success in delaying the development of AIDS in patients with HIV.  Since its introduction in the mid 1980s, it has prolonged the lives of mil�  lions of patients. It is particularly effective in preventing transmission of  HIV from infected pregnant women to their fetuses. Since it has a greater  effect on the replication of viRUSes than of body cells, it has fewer side  effects than most other AIDS drugs, though many patients nevertheless  cannot tolerate it. Because HIV rapidly becomes resistant to any single  antiretroviral drug, AZT is usually given in combination with other drugs.</p><p>Aztec NAHUATL-speaking people who in the 15th and early 16th centu�  ries ruled a large empire in what is now central and southern Mexico.  They may have originated on the northern Mexican plateau before migrat�  ing to their later location. Their migration may have been linked to the  collapse of the Toltec civilization. The Aztec empire, which at its height  comprised roughly five to six million people spread over some 80,000 sq  mi (200,000 sq km), was made possible by their successful agricultural  methods, including intensive cultivation, irrigation, and reclamation of  wetlands. The Aztec state was despotic, militaristic, and sharply stratified  according to class and caste. Aztec religion was syncretic, drawing espe�  cially on the beliefs of the Maya. The Aztec practiced human sacrifice, an  activity that sometimes reached mass proportions. The empire came to an  end when the Spanish conquistador Hernan Cortes took the emperor Mon�  tezuma II prisoner and conquered the great city Tenochtitlan (modem  Mexico City).

The members initially sup�  ported themselves by bank robberies and engaged in  terrorist bombings and arson, especially of West German and U.S. targets  in West Germany. Baader, Meinhof, and 18 others were arrested in 1972;  Meinhof eventually hanged herself, and Baader apparently also died a  suicide. By the mid-1970s the group had turned to international terrorism;  two members took part in the 1976 Palestinian airplane hijacking in the  Entebbe incident. After the collapse of communism in East Germany (1989�  90), it was discovered that East Germany�s secret police had provided  training and supplies to the gang.

In  the mythology of Canaan, he was locked in combat with Mot, the god of  death and sterility; depending on the outcome of their struggles, seven-  year cycles of fertility or famine would ensue. Baal was also king of gods,  having seized the kingship from the sea god, Yamm. Baal worship was  popular in Egypt from the later New Kingdom to its end (1400-1075 bc).  The Aramaeans used the Babylonian pronunciation Bel; Bel became the  Greek Belos, identified with Zeus. The Old Testament often refers to a spe�  cific local Baal or multiple Baalim.</p><p>ba'al shem \bal-'sham\ In Judaism, a title bestowed on men who worked  wonders and cures through secret knowledge of the names of God. The  practice dates to the 11th century, long before the term was applied to  certain rabbis and Kabbalists. They were numerous in 17th- and 18th-  century eastern Europe, where they exorcised demons, inscribed amulets,  and performed cures using herbs, folk remedies, and the Tetragrammaton.  Because they combined faith healing with use of the Kabbala, they clashed  with physicians, rabbis, and followers of the Haskala. See also Ba'al Shem  Tov.</p><p>Ba'al Shem Tov Vbal-'shem-'tovV orig.

An orphan, he worked in synagogues and  yeshivas, and when he retired to the Carpathian Mountains to engage in  mystical speculation he gained a reputation as a ba'al shem, or healer. From  c. 1736 he lived in the village of Medzhibozh and devoted himself to  spiritual pursuits. He was widely known as the Besht, an acronym of Ba'al  Shem Tov. He rejected the asceticism of older rabbis and focused on  communion with God, service of God in everyday tasks, and rescue of  the sparks of divinity that, according to the Kabbala, are trapped in the  material world. His discourses during Sabbath meals have been preserved;  he left no writings of his own. He made a point of conversing with simple</p><p>working people.

The son of a merchant, he  was influenced by the ShaykhI school of ShTite Islam.  In 1844 he wrote a commentary on the surah of Joseph  in the Qur�an and declared himself the Bab (Arabic:  �Gateway�) to the hidden imam. Later he would claim to  be the imam himself, and finally a divine manifestation.  The same year he assembled 18 disciples, who spread the new  faith in the various Persian provinces. He had popular support but was  opposed by members of the religious class, and he was arrested near  Tehran in 1847 and imprisoned.

Surrounded by  enemy states, Babur (the name means �Tiger�) persuaded his homesick  troops to stand their ground, and over the next four years he defeated his  foes. His grandson Akbar consolidated the new empire. Babur was also a  gifted poet and a lover of nature who constructed gardens wherever he  went. The Babur-ndmeh, his prose memoirs, has become a world classic  of autobiography.</p><p>Babuyan \,ba-bu-'yan\ Islands Island group, northern Philippines.  Lying north of Luzon, it consists of about 24 islands with a total area of  225 sq mi (583 sq km). The chief islands are Babuyan, Camiguin,  Calayan, Fuga, and Dalupiri. Calayan is the largest town and only port.</p><p>baby boom In the U.S., increase in the birth rate between 1946 and  1964; also, the generation born in the U.S. during that period. The hard�  ships and uncertainties of the Great Depression and World War II led many  unmarried couples to delay marriage and many married couples to delay  having children. The war�s end, followed by a sustained period of eco�  nomic prosperity (the 1950s and early 1960s), was accompanied by a  surge in population. The sheer size of the baby-boom generation (some  75 million) magnified its impact on society: the growth of families led to  a migration from cities to suburbs in the postwar years, prompting a  building boom in housing, schools, and shopping malls. As the �boomers�  reached young adulthood in the 1960s and �70s, their tastes in music and  their hair and dress styles strongly influenced the national culture, and the  political activism of some contributed to the unpopularity of the Vietnam  War. As they aged and prospered in the 1980s and �90s, their buying hab�  its determined the course of many consumer industries, including auto�  mobiles.

It became  the symbol of the first stage of killing during the Holocaust and of the  massacres by the Einsatzgruppen (German: �deployment groups�)�the  mobile killing units. The site came to world attention after the 1961 pub�  lication of Yevgeny Yevtushenko�s poem Baby Yar. Though a small obelisk  and memorial were erected in the 1960s and �70s, not until 1991 was the  identity of the Jewish victims recorded on the monument by the newly  independent Ukrainian government.</p><p>Babylon Ancient Middle Eastern city. The city�s ruins are located about  55 mi (89 km) south of Baghdad, near the modern city of Al-Hillah, Iraq.  Babylon was one of the most famous cities in antiquity. Probably first  settled in the 3rd millennium bc, it came under the rule of the Amorite  kings around 2000 bc. It became the capital of Babylonia and was the chief  commercial city of the Tigris and Euphrates river system. Destroyed by  Sennacherib in 689 bc, it was later rebuilt. It attained its greatest glory as  capital of the Neo-Babylonian empire under Nebuchadrezzar II (r. 605-c.  561 bc). Alexander the Great, who took the city in 331 bc, died there. Evi�  dence of its topography comes from excavations, cuneiform texts, and  descriptions by the Greek historian Herodotus. Most of the ruins are from  the city built by Nebuchadrezzar. The largest city in the world at the time,  it contained many temples, including the great temple of Marduk with its  associated ziggurat, which was apparently the basis for the story of the  Tower of Babel. The Hanging Gardens, a simulated hill of vegetation-clad  terracing, was one of the Seven Wonders of the World.</p><p>Babylonia Ancient cultural region of the Tigris and Euphrates river sys�  tem. The area was divided into Sumer (southeast) and Akkad (northwest)  when the first Babylonian line of Amorite kings took power after 2000  bc. Largely because of the efforts of Hammurabi (r. c. 1792-50 bc), Baby�  lonia gained regional hegemony but declined after his death; the Kassites  from the east eventually assumed power (c. 1595) and established a  dynasty that lasted some four centuries. After Elam conquered Babylonia  (c. 1157 bc), a series of wars established a new Babylonian dynasty whose  outstanding member was Nebuchadrezzar I (r. c. 1124-1103 bc). Follow�  ing his rule, a three-way struggle developed for control of Babylonia  among Assyria, Aram (see Aramaeans), and Chaldea, in which the Assyr�  ians ruled the area most frequently (9th-7th century bc). In the 7th-6th  centuries bc the Chaldean Nebuchadrezzar II (605-562 bc) instituted the  last and greatest period of Babylonian supremacy, conquering Syria and  Palestine and rebuilding Babylon, the capital city. It was conquered in 539  bc by the Persian Achaemenian dynasty under Cyrus II and in 331 bc by  Alexander the Great, after which the capital city was gradually abandoned.</p><p>Babylonian Exile or Babylonian Captivity Forced detention of  Jews in Babylonia following Babylonian conquest of Judah in 598/597  and 587/586 bc. The first deportation may have occurred after King Jehoi-  achin was deposed in 597 bc or after Nebuchadrezzar destroyed Jerusalem  in 586. In 538 bc the Persian Cyrus II conquered Babylonia and allowed  the Jews to return to Palestine. Some Jews chose to remain in Babylonia,  initiating the Jewish Diaspora. During the Babylonian Exile the Jews  maintained their national spirit and religious identity despite cultural pres�  sures in a foreign land, with Ezekiel and other prophets keeping hope alive.  Petrarch and other writers designated the Avignon papacy as the Babylo�  nian Captivity in the 14th century, and Martin Luther used the term in the  title of one of his works attacking the papacy and the Roman Catholic  church in the 16th century.</p><p>baby's breath Either of two species of herbaceous plants of the genus  Gypsophila (pink family), having profuse small blossoms.

In basic baccarat the house is the bank. In chemin de fer (a more  advanced baccarat) the bank passes from player to player. In punto banco,  it appears to pass from player to player but is actually held by the house.  Casino play involves three or six 52-card decks shuffled together and dealt  from a shoe (a box designed to hold several decks of playing cards).  Counting spot-cards at face value and face-cards and 10s as 0, the bet�  tor�s aim is to receive cards that are closer to totaling 9 than those of the  banker. For the purpose of totaling these cards, 10 or more counts only  as its last digit (for instance, 17 is counted as 7). The banker deals two  cards to the bettor and to himself.</p><p>Baccarat glass Glassware manufactured since 1765 in Baccarat,  France. The firm originally produced soda glass for windows and indus�  trial use. In 1816 it was acquired by a Belgian manufacturer of lead crys�  tal; since then it has specialized in this type of glass, especially  paperweights. Baccarat exhibited works in the important 1925 Exposition  des Arts Decoratifs et Industriels Modemes in Paris.

Bacchanalia were intro�  duced from lower Italy into Rome, where they were at first secret, open  only to women, and held three times a year. They later admitted men and  became as frequent as five times a month.

March 21, 1685, Eisenach, Thuringia,  Ernestine Saxon Duchies�d. July 28, 1750, Leipzig) German composer.  Born to a musical family, he became a superbly well-rounded musician;  from 1700 he held positions as singer, violinist, and organist. His first  major appointment, in 1708, was as organist at the ducal court at Weimar.  This was followed by a six-year stay (1717-23) as kapellmeister at the  princely court of Kothen, which was in turn followed by his appointment  as cantor at the great church of St. Thomas in Leipzig, where he would  remain for the rest of his life. Imbued with the northern German contra�  puntal style (see counterpoint) from early childhood, he encountered the  lively Italian style, especially in the works of Antonio Vivaldi, about 1710,  and much of his music embodies an immensely convincing melding of  the two styles. At St. Thomas he wrote more than 200 church cantatas.  His orchestral works include the six Brandenburg Concertos, four orches�  tral suites, and many harpsichord concertos, a genre he invented. His solo  keyboard works include the great didactic set The Well-Tempered Clavier  (1722 and 1742), the superb Goldberg Variations (1742), the massive but  unfinished Art of the Fugue (1749), numerous suites, and many organ  preludes and fugues. His surviving choral works include (in addition to  the sacred cantatas) more than 30 secular cantatas, two monumental Pas�  sions, and the Mass in B Minor. His works, never widely known in his  lifetime, went into near-total eclipse after his death, and only in the early  19th century were they revived, to enormous acclaim. He was perhaps the  most accomplished organist and harpsichordist of his time. Today Bach  is regarded as the greatest composer of the Baroque era, and, by many,  as the greatest composer of all time.</p><p>Bach, Wilhelm Friedemann (b. Nov. 22, 1710, Weimar, Saxe-  Weimar�d.

One of the  finest organists of his time, he held important organist posts in Dresden  (1723-46) and Halle (1746-64) but thereafter lived an unsettled life and  drifted into drinking and poverty. Though he was a highly gifted com�  poser, his compositions veered confusingly between the old contrapuntal  style and the new pre-Classical styles. He wrote more than 30 church can�  tatas, several keyboard concertos, and many solo keyboard works.</p><p>Bacharach Vbak-o-.rakN, Burt (b.

Stones  are moved from point to point in opposite directions according to the  number of points shown on the dice. On getting all 15 of his stones into  his own home (inner) table, a player may begin �bearing off��moving  his stones to an imaginary point beyond the edge of the board.

With  no formal art training, he started painting, drawing, and participating in  gallery exhibitions, with little success. In 1944 he achieved instant noto�  riety with a series of controversial paintings, Three Studies for Figures at  the Base of a Crucifixion. His mature style emerged completely with the  series of works known as �The Screaming Popes� (1949-mid- 1950s), in  which he converted Diego Velazquez�s famous Portrait of Pope Innocent  X into a nightmarish icon of hysterical terror. Most of Bacon�s paintings  depict isolated figures, often framed by geometric constructions, and ren�  dered in smeared, violent colours.

A supporter of the Earl of Essex, Bacon turned against him when Essex  was tried for treason. Under James I he rose steadily, becoming succes�  sively solicitor general (1607), attorney general (1613), and lord chan�  cellor (1618). Convicted of accepting bribes from those being tried in his  court, he was briefly imprisoned and permanently lost his public offices;  he died deeply in debt. He attempted to put natural science on a firm  empirical foundation in the Novum Organum (1620), which sets forth his  scientific method. His elaborate classification of the sciences inspired the  18th-century French Encyclopedists (see Encyclopedie), and his empiricism  inspired 19th-century British philosophers of science.

He therefore represents a historically precocious expression of  the empirical spirit of experimental science, even though his actual prac�  tice of it seems to have been exaggerated. His philosophical thought was  essentially Aristotelian, though he was critical of the methods of theolo�  gians such as Albertus AAagnus and Thomas Aquinas, arguing that a more  accurate experimental knowledge of nature would be of great value in  confirming the Christian faith. He also wrote on mathematics and logic.  He was condemned to prison c. 1277 by his fellow Franciscans because  of �suspected novelties� in his teaching.</p><p>bacteremia V.bak-te-'re-me-oN Presence of bacteria in the blood. Short�  term bacteremia follows dental or surgical procedures, especially if local  infection or very high-risk surgery releases bacteria from isolated sites.  In some cases, prior antibiotic therapy can prevent this. It causes little  problem to a healthy immune system but can be serious for those with  prostheses (where infection can center) or high susceptibility to bacterial  invasion. Extensive bacteremia can release toxins into the blood (septice�  mia), leading to shock and vascular collapse. Antibiotic-resistant bacteria  have increased the rate of severe bacteremia.</p><p>bacteria Group of microscopic, single-celled organisms that are  prokaryotes. They may have spherical, rodlike, or spiral shapes. They  inhabit virtually all environments, including soil, water, organic matter,  and the bodies of multicellular animals. Different types are distinguished  in part by the structure of their cell walls, which is determined by gram  stain. Many bacteria swim by means of flagella (see flagellum). The DNA  of most bacteria is found in a single circular chromosome and is distrib�  uted throughout the cytoplasm rather than contained within a membrane-  enclosed nucleus. Though some bacteria can cause food poisoning and  infectious diseases in humans, most are harmless and many are benefi�  cial. They are used in various industrial processes, especially in the food  industry (e.g., the production of yogurt, cheeses, and pickles). Bacteria  are divided into eubacteria and archaebacteria. See also budding bacteria,</p><p>COLIFORM BACTERIA, CYANOBACTERIA, DENITRIFYING BACTERIA, NITRIFYING BACTERIA,  SHEATHED BACTERIA, SULFUR BACTERIA.</p><p>bacterial diseases Diseases caused by bacteria. The most common  infectious diseases, they range from minor skin infections to bubonic  plague and tuberculosis. Until the mid-20th century, bacterial pneumonia  was probably the leading cause of death among the elderly. Improved  sanitation, vaccines, and antibiotics have all decreased the mortality rates  from bacterial infections, though antibiotic-resistant strains have caused a  resurgence in some illnesses. Bacteria cause disease by secreting or  excreting toxins (as in botulism), by producing toxins internally, which are  released when the bacteria disintegrate (as in typhoid), or by inducing sen�  sitivity to their antigenic properties (as in tuberculosis). Other serious bac�  terial diseases include cholera, diphtheria, bacterial meningitis, and syphilis.</p><p>bacteriology Study of bacteria. Modern understanding of bacterial  forms dates from Ferdinand Cohn�s classifications. Other researchers, such  as Louis Pasteur, established the connection between bacteria and fermen�  tation and disease. The modern methods of bacteriological technique  began in the late 19th century with the use of stains and the development  of methods of cultivating organisms on plates of nutrients. Important dis�</p><p>coveries came when Pasteur succeeded in immunizing animals against  two bacterial diseases, which led to the development of immunology. See  also microbiology.</p><p>bacteriophage \bak-'tir-e-3-,faj\ or phage Any of a group of usu�  ally complex viRUSes that infect bacteria. Discovered in the early 20th cen�  tury, bacteriophages were used to treat human bacterial diseases such as  bubonic plague and cholera but were not successful; they were abandoned  with the advent of antibiotics in the 1940s. The rise of drug-resistant bac�  teria in the 1990s focused renewed attention on the therapeutic potential  of bacteriophages. Thousands of varieties exist, each of which may infect  only one or a few types of bacteria. The core of a bacteriophage�s genetic  material may be either DNA or RNA. On infecting a host cell, bacterioph�  ages known as lytic or virulent phages release replicated viral particles  by lysing (bursting) the host cell. Other types, known as lysogenic or  temperate, integrate their nucleic acid into the host�s chromosome to be  replicated during cell division. During this time they are not virulent. The  viral genome may later become active, initiating production of viral par�  ticles and destruction of the host cell. A.D. Hershey and Martha Chase  used a bacteriophage in a famous 1952 experiment that supported the  theory that DNA is the genetic material. Because bacteriophage genomes  are small and because large quantities can be prepared in the laboratory,  they are a favourite research tool of molecular biologists. Studies of  phages have helped illuminate genetic recombination, nucleic acid repli�  cation, and protein synthesis.</p><p>Bactria Ancient country, Central Asia.

The game is named after the  residence of Britain�s duke of Beaufort, where it supposedly originated  c. 1873. Officially sanctioned badminton matches are played indoors to  protect the shuttlecock from winds. Play consists entirely of hitting the  shuttlecock back and forth without letting it touch the floor or ground.  The best-known match is the All-England Championships. Badminton  became a full-medal sport at the 1992 Olympics.

He governed  Libya (1928-34) and commanded the Italian forces in Ethiopia (1935�  36). In 1940 he resigned as chief of staff in disagreement with Benito  Mussolini, and in 1943 he helped organize Mussolini�s downfall. As prime  minister (1943^44), Badoglio extricated Italy from World War II by  arranging for an armistice with the Allies.</p><p>BAE Systems British manufacturer of aircraft, missiles, avionics, naval  vessels, and other aerospace and defense products. BAE Systems was  formed (1999) from the merger of British Aerospace (BAe) with Marconi  Electronic Systems. BAe, in turn, dates to the merger (1977, with two  other firms) of British Aircraft Corporation (BAC) and Hawker Siddeley  Aviation, both having been nationalized a year earlier owing to unprof�  itable financial situations. Through its BAe antecedents, BAE Systems  carries the legacy of some 20 British aircraft firms (e.g., Bristol, Avro,  Gloster, De Havilland, Supermarine), several dating to the first decades  of flight. In the 1960s and early �70s, BAC and Hawker Siddeley each  produced significant aircraft. BAC built the Vickers-Armstrongs VC 10  and BAC One-Eleven jetliners and, in partnership with Aerospatiale of  France, the Concorde supersonic transport. Hawker Siddeley developed  the HS 121 Trident jetliner, Vulcan bomber, and Harrier vertical/short-  takeoff-and-landing (V/STOL) fighter. In 1979 British Aerospace joined  the Airbus Industrie jetliner-manufacturing consortium, and during the early  1980s it became privatized. In the 1990s it became a partner with firms  in Germany, Italy, and Spain in the Eurofighter Typhoon program. It also  joined a venture led by Lockheed Martin to develop the Joint Strike Fighter.</p><p>Baeck VbekV Leo (b. May 23, 1873, Lissa, Posen, Prussia�d. Nov. 2,  1956, London, Eng.) Prussian-Polish rabbi, spiritual leader of German  Jewry during the Nazi period. After earning his Ph.D. in philosophy at the  University of Berlin, he served as a rabbi in Silesia, Diisseldorf, and Ber�  lin, becoming the leading liberal Jewish religious thinker of his time. He  synthesized Neo-Kantianism and rabbinic ethics in The Essence of Juda�  ism (1905) and considered the Christian gospels as rabbinic literature in  The Gospel as a Document of Jewish Religious History (1938). He nego�  tiated with the Nazis to buy time for the German Jews; finally arrested,  he was sent to the Theresienstadt concentration camp, where he wrote  and lectured on Plato and Immanuel  Kant. Liberated in 1945 on the day  before he was to be executed, he  settled in England.</p><p>Baedeker Vbed-o-korV, Karl (b.</p><p>Nov. 3, 1801, Essen, Duchy of  Oldenburg�d.

Prussian-bom Estonian  embryologist. Studying chick development with Christian Pander (1794-  1865), Baer expanded Pander�s concept of germ layer formation to all  vertebrates, thereby laying the foundation for comparative embryology.  He emphasized that embryos of one species could resemble embryos (but  not adults) of another and that the younger the embryo, the greater the  resemblance, a concept in line with his belief that development proceeds  from simple to complex, from like to different. He also discovered the  mammalian ovum. His On the Development of Animals (2 vol., 1828-37)  surveyed all existing knowledge on vertebrate development and estab�  lished embryology as a distinct subject of research.</p><p>baetylus or baetulus Vbe-to-bs, 'be-tyo-bsV In Greek reugion, a  sacred stone or pillar.

Located on the Tigris River, the site has been settled from  ancient times. It rose to importance after being chosen in ad 762 by Caliph  al-Mansur (r. 754-775) as the capital of the �Abbasid dynasty. Under HarOn  al-Rashid it achieved its greatest glory�reflected in the many tales from  The Thousand and One Nights that were set there�as one of the world�s  largest and wealthiest cities. A centre of Islamic civilization, it was sec�  ond only to the Byzantine capital, Constantinople (modem Istanbul), in  trade and culture. The capital was moved briefly to Samarra� in 836, after  which the city was prone to bouts of political instability. It was sacked  by the Mongols under Hiilegu in 1258, taken by Timur in 1401, and cap�  tured by the Persian Safavid dynasty in 1508. Under the sultan SOleyman I,  the city became part of the Ottoman Empire in 1534 and remained so�save  for a brief period (1623-38) when it returned to Safavid rule�until the  end of World War I (1914�18). It became capital of the kingdom (1920)  and then the republic (1958) of Iraq. During the 20th century the city grew  greatly in size and population. It was severely damaged during the First  and Second Persian Gulf wars (1990-91 and 2003, respectively), and from  2003 it was occupied by a U.S.-led coalition force.</p><p>bagpipe Wind instrument consisting of two or more single- or double�  reed pipes, the reeds being vibrated by wind fed by arm pressure on a  skin or cloth bag. The pipes are held in wooden sockets tied into the bag,  which is inflated either by the mouth or by bellows strapped to the body.  Melodies are played on the fingerholes of the melody pipe, or chanter,  while the remaining pipes, or drones, sound single notes. Bagpipes existed  by about ad 100. The early bag was an animal bladder or a nearly whole  sheepskin or goatskin. Bagpipes have always been folk instruments, but  after the 15th century some were used for court music, and others have  survived as military instruments. An important related instrument is the  Irish union (or uilleann) pipe.</p><p>Baguirmi or Bagirmi \ba-ger-'me\ Former sultanate, now part of  southwestern Chad. Located southeast of Lake Chad, it was probably</p><p>established in the 16th century. The king ruled from the capital city of  Massenya. Though the 17th century brought prosperity as a result of the  slave trade, Baguirmi became a pawn in conflicts between rival empires  to the east and west.

MTrzd Hoseyn c Ali Nurl (b. Nov.  12, 1817, Tehran, Iran�d. May 29, 1872, Acre, Palestine) Iranian reli�  gious leader, founder of the BahaI faith. A ShTite Muslim who allied him�  self with the Bab, he joined his half brother Mlrza Yahya (known as Sobh-e  Azal) in leading the Bab! movement after the Bab�s execution. Sunnite  Muslims exiled him to Baghdad, Kurdistan, and finally Constantinople,  where in 1867 he declared himself the imam-mahdi foretold by the Bab  and sent by God. This pronouncement split Babism into two factions, with  a small group (the Azau) adhering to its original beliefs and a larger group  following him into what became the Baha�i faith. The Ottoman govern�  ment banished him to Acre where, as Baha� Ullah, he developed Baha�i  into a teaching that advocated the unity of all religions and universal  human brotherhood.</p><p>Baha�i \ba-'ha-e\ Religion founded in Iran in the mid-19th century by  Baha� Ullah. It emerged from Babism when in 1863 Baha� Ullah asserted  that he was the messenger of God predicted by the Bab. Before his death  in 1892, he appointed his son c Abd ol-Baha to lead the community. The  writings of the Bab, Baha� Ullah, and �Abd ol-Baha form the sacred lit�  erature. Worship consists of readings from scriptures of all religions.  Baha�i faith proclaims the essential unity of all religions and the unity of  humanity. It is concerned with social ethics and has no priesthood or sac�  raments. Because of its 19 initial disciples, it considers the number 19  sacred, and the calendar consists of 19 months of 19 days (with four addi�  tional days). Adherents are expected to pray daily, fast 19 days a year, and  keep to a strict ethical code. Baha�i has experienced major growth since  the 1960s but has been persecuted in Iran since the fundamentalist revo�  lution of 1979.</p><p>Bahamas, The officially Commonwealth of The Bahamas</p><p>Archipelago and state, northwestern edge of the West Indies, lying south�  east of Florida and north of Cuba. It consists of about 700 islands and  numerous cays. Area: 5,382 sq mi (13,939 sq km). Population (2005 est.):  323,000. Capital: Nassau (on New Providence Island). The people are of  African and European ancestry, a legacy of the slave trade. Language:  English (official). Religion: Christianity (mostly Protestant; also Roman  Catholic, other Christians). Currency: Bahamian dollar. Chief among the  islands, from north to south, are Grand Bahama, Abaco, Eleuthera, New  Providence, Andros, Cat, and Inagua; New Providence has most of the  population. All are composed of coralline limestone and lie mostly only  a few feet above sea level; the highest point is Mount Alvernia (206 ft  [63 m]) on Cat Island. There are no rivers. The country�s market economy  is heavily dependent on tourism, for which gambling is a particular attrac�  tion, and on international financial services. Most foodstuffs are imported  from the U.S.; fish and rum are significant exports. The Bahamas is a con�  stitutional monarchy with two legislative houses; its chief of state is the  British monarch, represented by a governor-general, and the head of gov�  ernment is the prime minister. The islands were inhabited by Arawak  Indians when Christopher Columbus sighted them on Oct. 12, 1492. Many  scholars believe Columbus landed on San Salvador (Watling) Island,  though others contend his first landfall was on Samana Cay (Cat Island).  The Spaniards made no attempt to settle but carried out slave raids that  depopulated the islands; when English settlers arrived in 1648 from Ber�  muda, the islands were uninhabited.

Bil Baird  (originally William Britton Baird) worked under the puppeteer Tony Sarg  for five years then produced his own puppet shows from the mid 1930s.  He and Cora Eisenberg married in 1937 and began to create original pup�  pets, scenery, and music for their shows. They produced a series of tele�  vision shows in the 1950s and opened their own marionette theatre in New  York in 1966. Bil wrote The Art of the Puppet (1965) and trained pup�  peteers such as Jim Henson.</p><p>Baird, John L(ogie) (b. Aug. 13, 1888, Helensburgh, Dunbarton,  Scot.�d. June 14, 1946, Bexhill-on-Sea, Sussex, Eng.) Scottish engineer.  Plagued by ill health, he gave up his job as an electric-power engineer in  1922 and devoted himself to television research. He produced televised  objects in outline in 1924 and recognizable human faces in 1925, and in  1926 became the first person to televise pictures of objects in motion. He  demonstrated colour television in 1928. The German post office gave him  facilities to develop a television service in 1929. When the BBC televi�  sion service began (1936), his system competed with that of Marconi  Electric and Musical Industries; the BBC adopted the latter exclusively  in 1937. Baird was reported to have completed research on stereoscopic  television at the time of his death.</p><p>Bairiki Vbl-,re-ke\ Islet (pop., 2000: urban agglomeration, 36,717) and  administrative centre, Kiribati.

Bounded by the U.S. to the north, the Pacific Ocean  to the west, and the Gulf of California to the east, it is about 760 mi (1,220  km) long and has an area of 55,366 sq mi (143,396 sq km). Politically, it  is divided into the states of Baja California and Baja California Sur. It has  more than 2,000 mi (3,200 km) of coastline, with sheltered harbours on  both the western and gulf coasts. The area had been inhabited for some  9,000 years when the Spanish arrived in 1533. Jesuit missionaries estab�  lished permanent settlements in the late 17th century, but the native Indi�  ans were practically exterminated in epidemics introduced by the Spanish.  The area was separated from what is now the U.S. state of California by  treaty in 1848 following the Mexican War.</p><p>Baja California formerly Baja California Norte State (pop.,  2000: 2,487,367), northern Baja California peninsula, northwestern  Mexico. It covers an area of 27,071 sq mi (70,114 sq km), and its capital  is Mexicali. Although long inhabited, it remained sparsely populated until  the 1950s, when it experienced phenomenal growth. This was partly  because of its proximity to the U.S. border; numerous foreign companies  have established assembly oriented factories (maquiladoras) in the region,  a trend accelerated by the establishment of NAFTA in 1994.</p><p>Baja California Sur State (pop., 2000: 423,516), southern Baja Cali�  fornia peninsula, northwestern Mexico. It occupies an area of 28,369 sq  mi (73, 475 sq km), and its capital is La Paz. It became a state in 1974. It  is sparsely populated and remains relatively underdeveloped. Much new  acreage of cotton has been planted near La Paz, but subsistence agricul�  ture is most common. An increase in tourism and improved communica�  tions have begun to alleviate the state�s isolation.</p><p>Baker, Chet orig. Chesney Henry Baker (b. Dec. 23, 1929, Yale,  Okla., U.S.�d.

His sub�  dued tone and gentle phrasing made him the epitome of the cool jazz (see  bebop) of the 1950s. With recordings such as �My Funny Valentine� he  established his plaintive, fragile approach as a vocalist, which mirrored  his trumpet style. Much of his later career, interrupted several times by  legal problems stemming from drug addiction, was spent in Europe.</p><p>Baker, Josephine orig. Freda Josephine McDonald (b.

She went to Paris in 1925 to  dance in La Revue negre. To French  audiences she personified the exoti�  cism and vitality of African Ameri�  can culture, and she became Paris�s  most popular music-hall entertainer,  receiving star billing at the Foues  Bergere. In World War II she worked  with the Red Cross and entertained  Free French troops.

They  speak a dialect of Luri (a language related to Modern Persian) and are  mostly Shi'ite Muslims. Their two tribal groups are the Chahar Lang and  Haft Lang; the position of leader of all the Bakhtyarl alternates every two  years between the chiefs of the two tribal groups. Many chiefs have been  influential in national public affairs and have held office. Bakhtyarl  women are normally better-educated and freer than other Muslim women  in Iran.</p><p>baking Process of cooking by dry heat, especially in an oven. Baked  products include bread, cookies, pies, and pastries. Ingredients used in  baking include flour, water, leavening agents (baker�s yeast, baking soda,  baking powder), shortening (fats, oils), eggs, milk, and sugars. These are  mixed together to create dough or batter, which is then transferred to a  pan or sheet and heated. Leavening agents produce gas that becomes  trapped in the dough, causing it to rise. Shortening makes doughs more  easily workable and the final product more tender. Egg whites are used  to produce a light, airy texture, and yolks contribute colour, flavour, and  texture. Milk is used for moistening and flavouring and sugars for sweet�  ening and aiding fermentation.</p><p>baking soda See bicarbonate of soda</p><p>Bakke \'ba-ke\ decision formally Regents of the University of  California v.

In 1723 Peter I (the Great) took Baku, but it was returned to Persia  in 1735; Russia recaptured it in 1806. It was the capital of the short-lived  independent state of Azerbaijan (1918-20) and in 1920 became the capi�  tal of the new Soviet republic of Azerbaijan. The basis of Baku�s economy  is petroleum.

Balaguer was vice president under Trujillo�s brother Hector and  became president when Hector resigned, but Trujillo continued to wield  actual power until assassinated in 1961. Balaguer�s subsequent attempts  at liberalization caused his overthrow by the military. Elected president  in 1966 after the U.S. military intervention in 1965, he achieved steady  economic growth and modest social reforms. He was reelected repeat�  edly, but his last term was shortened by two years amid political violence  and charges of electoral fraud and corruption.</p><p>Balakirev \bo Ta-kyi-ryif\, Mily (Alekseyevich) (b. Jan. 2, 1837,  Nizhny Novgorod, Russia�d. May 29, 1910, St. Petersburg) Russian  composer. As a youth he met and was influenced by the nationalist com�  poser Mikhail Glinka. Balakirev himself later became the mentor of Cesar  Cui (1835-1918) and Modest Mussorgsky; in 1861-62 their group  expanded to become The Five. In 1862 Balakirev cofounded the Free  School of Music. His works include two symphonies, the piano fantasy  Islamey (1869), music for King Lear (1858-61), and a piano concerto.  With his colourful imagination and use of folk themes, he was perhaps  the most influential proponent of Russian nationalism. After a nervous  breakdown in 1871, he adopted a fervent and bigoted form of Orthodoxy  and was thereafter involved in musical life only sporadically.</p><p>Balaklava \b9-l3-'kla-v9\, Battle of (Oct. 25, 1854) Indecisive mili�  tary engagement of the Crimean War.

The equal-arm  balance dates back to the ancient  Egyptians, possibly as early as 5000  bc. By the early 20th century, it had  been developed into an exquisitely  precise measuring device. Electronic  balances today depend on electrical  compensation rather than mechani�  cal deflection. The ultramicrobal�  ance is any weighing device that  serves to determine the weight of  even smaller samples than can be  weighed with the microbalance  (which can weigh samples as small  as a few milligrams), that is, total  amounts as small as a few micro�  grams.</p><p>balance of payments System�  atic record of all economic transac�  tions during a given period between</p><p>residents (including the government) of one country and residents (includ�  ing the governments) of other countries. The transactions are presented  in the form of double-entry bookkeeping. The U.S. balance of payments,  for example, records the various ways in which dollars are made avail�  able to foreigners through U.S. imports, U.S. tourist spending abroad, for�  eign lending, and so on. These expenditures are shown on the debit side  of the balance. The credit side shows the various uses to which foreign�  ers put their dollars, including paying for U.S. exports, servicing debts to  the U.S., and the like. Foreign countries may acquire more dollars than  they need to spend on U.S. goods and services and may hold the surplus  or purchase gold or securities; or they may have fewer dollars than they  need to purchase U.S. goods and services, and may acquire additional  dollars by transferring gold, selling holdings in the U.S., and so on. Cer�  tain forms of transferring funds (e.g., large outflows of gold) are less  desirable as a way of settling foreign debts than others (e.g., transfers of  currency acquired through international trade). The International Mon�  etary Fund helps address problems relating to balance of payments.

The term came into use  at the end of the Napoleonic Wars to denote the power relationships in  the European state system. Until World War I, Britain played the role of  balancer in a number of shifting alliances. After World War II, a North�  ern Hemisphere balance of power pitted the U.S. and its allies (see NATO)  against the Soviet Union and its satellites (see Warsaw Pact) in a bipolar  balance of power backed by the threat of nuclear war. China�s defection  from the Soviet camp to a nonaligned but covertly anti-Soviet stance pro�  duced a third node of power. With the Soviet Union�s collapse (1991), the  U.S. and its NATO allies were recognized universally as the world�s para�  mount military power.</p><p>balance of trade Difference in value over a period of time between  a nation�s imports and exports of goods and services. The balance of trade  is part of a larger economic unit, the balance of payments, which includes  all economic transactions between residents of one country and those of  other countries. If a nation�s exports exceed its imports, the nation has a</p><p>favourable balance of trade, or a trade surplus. If imports exceed exports,  an unfavourable balance of trade, or a trade deficit, exists. Under mercan�  tilism a favourable balance of trade was an absolute necessity, but in clas�  sical economics it was more important for a nation to utilize its economic  resources fully than to build a trade surplus. The idea of the undesirabil�  ity of trade deficits persisted, however, and arguments against deficits are  often advanced by advocates of protectionism.</p><p>balance sheet Financial statement that describes the resources under  a company�s control on a specified date and indicates where they have  come from.

Other  causes of permanent baldness are skin diseases and injuries, inborn lack  of hair development, and severe follicle injury. Temporary hair loss may  follow high fever or come from X rays, drugs, malnutrition, or endocrine  disorders. Alopecia areata, with sharply outlined patches of sudden com�  plete baldness, is also usually temporary.</p><p>Baldovinetti X.bal-do-ve-'nat-teV, Alesso (b. Oct. 14, 1425?,  Florence�d. Aug. 29, 1499, Flo�  rence ) Italian artist active in Flo�  rence. Little is known of his early  training, but his style shows the  influence of Fra Angelico and  Domenico Veneziano. Both his mas�  terpiece, The Nativity (1460-62), a  fresco in the church of the Santis-  sima Annunziata, Florence, and his  Madonna and Child (1460s) in the  Louvre depict views of the Arno  River valley in the background; they  are among the earliest European  paintings of landscapes. His work,  though seldom innovative, exempli�  fied the careful modeling of form and  the accurate depiction of light char�  acteristic of the most progressive  style of Florentine painting during  the last half of the 15 th century. He  also designed the mosaic decoration  over Lorenzo Ghiberti�s doors on the  Baptistery in Florence (1453-55)  and produced designs for stained  glass and intarsia.</p><p>Baldung Vbal-duqV Hans or Hans Baldung Grien \'gren\ (b. c.  1484, Schwabisch Gmtind, Wiirttemberg�d. 1545, Imperial Free City of  Strasbourg) German painter and graphic artist. He was assistant to Albre�  cht Durer in Ntimberg and was active in Strasbourg as official painter to  the episcopate. He is best known for the high altar of the cathedral at  Freiburg, where he lived in 1512-17. His output was varied and exten�  sive, encompassing religious paintings, allegories, mythologies, portraits,  designs for stained glass, tapestry, and book illustration. His paintings are  equaled in importance by his drawings, engravings, and woodcuts, fre�  quently depicting the themes of the �dance of death� and �death and the  maiden.� In his taste for the gruesome, Baldung is close in style and spirit  to Matthias GrOnewald.</p><p>Baldwin I (b. 1172, Valenciennes�d. 1205) First Latin emperor of  Constantinople (1204-05). Count of Flanders and Hainaut, he was a  leader of the Fourth Crusade, which was directed against the Byzantine  Empire. He helped install a pro-Latin emperor (1203). When the Crusad�  ers in Constantinople seized power, he was elected emperor (1204) and  recognized by the pope. He created a government on the western Euro�  pean model, granting Greek lands to his knights, but was defeated, taken  prisoner, and executed by invading Bulgars.</p><p>Baldwin I known as Baldwin of Boulogne \bu-'lon-y9\ (b.  1058?�d. April 2, 1118, Al-Arish, Egypt) King of Jerusalem (1100-18).  The son of a French count, he joined the First Crusade and created the  first Crusader state when he gained control of Edessa (now in Turkey) in  1098. In 1100 his brother Godfrey died in Jerusalem, and Baldwin was  summoned by the nobles to succeed him as king of the Crusader state and  defender of the Holy Sepulchre. He expanded the kingdom by conquer�  ing coastal cities such as Arsuf and Caesarea, built the important castle  Krak de Montreal, and established an administration that served for 200  years as the basis for Frankish rule in Syria and Palestine.</p><p>Baldwin II known as Baldwin of Bourg \'biirk\ (d. August 1131,  Jerusalem) King of Jerusalem (1118-31). A French nobleman, he joined  the First Crusade and was made count of Edessa by his cousin Baldwin I  in 1100. Captured by Seljuq Turks in 1104, he was ransomed four years  later and reclaimed Edessa from the regent by force. He became king of  Jerusalem in 1118 on the death of Baldwin I. He was held hostage by the  Turks 1123-24. He later expanded his kingdom and attacked Damascus  with the aid of the Knights of Malta and the Templars. He arranged the  marriage of his daughter Melisend to Fulk V of Anjou and made them his  successors.</p><p>Baldwin II Porphyrogenitus \,por-f3-ro-'jen-9t-9s\ (b. 1217,  Constantinople�d.

He sold sacred relics to Louis IX of France  and broke up parts of the imperial palace for firewood. He lost the throne  in 1261 when Michael VIII Palaeologus captured Constantinople and  restored Greek rule. Baldwin fled to Europe and later died in Sicily.</p><p>Baldwin IV known as Baldwin the Leper (b. 1161�d. March 1185,  Jerusalem) King of Jerusalem (1174-85). He was crowned at age 13 on  the death of his father, but the kingdom was ruled by a series of regents.  Baldwin was afflicted with leprosy throughout his short life, which con�  tributed to power struggles among the nobility. His defeat of Saladin in  1177 led to a two-year truce, but in 1183 Saladin captured Aleppo and  completed the encirclement of Jerusalem. Baldwin crowned his nephew  king in 1183.</p><p>Baldwin, James (Arthur) (b.</p><p>U.S.�d. Dec. 1, 1987, Saint-Paul,</p><p>France) U.S. essayist, novelist, and  playwright. He grew up in poverty in  the New York City district of Harlem  and became a preacher while in his  teens. After 1948 he lived alternately  in France and the U.S. His semiau-  tobiographical first novel, Go Tell It  on the Mountain (1953), regarded as  his finest, was followed by the essay  collections Notes of a Native Son  (1955) and Nobody Knows My Name  (1961); the novels Giovanni�s Room  (1956), a story of homosexual life,  and Another Country (1962); the  long polemical essay The Fire Next  Time (1963), prophesying wide�  spread racial violence; and the play  Blues for Mister Charlie (produced  1964). His eloquence and passion on  the subject of race made him for  years perhaps the country�s most  prominent black writer.</p><p>Baldwin, Robert (b. May 12, 1804, York, Upper Canada�d. Dec. 9,  1858, Toronto) Canadian politician. Called to the bar in 1825, Baldwin  began his political career as a member of the Legislative Assembly of  Upper Canada for York (1829-30). In 1 842�43 he and Louis Hippolyte  LaFontaine formed the first Liberal Party administration; when the Liber�  als returned to power in 1848, they were able to establish responsible, or  cabinet, government. He resigned in 1851.</p><p>Baldwin, Roger (Nash) (b. Jan. 21, 1884, Wellesley, Mass., U.S.�d.  Aug. 26, 1981, Ridgewood, N.J.) U.S. civil-rights leader. Born into an  aristocratic Massachusetts family, Baldwin attended Harvard University  and taught sociology at Washington University (1906-09) in St. Louis,  where he also was chief probation officer of the city�s juvenile court and  secretary of its Civic League. When  the U.S. entered World War I, he  became director of the pacifist  American Union Against Militarism,  the predecessor of the American Civil  Liberties Union (ACLU). As the  ACLU�s director (1920-50) and  national chairman (1950-55), he  made civil rights, once a predomi�  nantly leftist cause, a universal one.</p><p>Baldwin (of Bewdley), Stan�  ley Baldwin, 1st Earl (b. Aug.</p><p>3, 1867, Bewdley, Worcestershire,</p><p>Eng.�d. Dec. 14, 1947, Astley Hall,  near Stourport-on-Severn, Worces�  tershire) British politician. After  managing his family�s large indus�  trial holdings, he became a Conser�  vative member of the House of  Commons (1908-37). He served as  financial secretary of the treasury</p><p>(1917-21) and president of the Board of Trade (1921-22), then was  appointed prime minister (1923-24, 1924-29, 1935-37). He proclaimed  a state of emergency in the general strike of 1926 and later secured pas�  sage of the antiunion Trade Disputes Act. As prime minister after 1935,  he began to strengthen the British military while showing little public  concern about the aggressive policies of Germany and Italy. He was criti�  cized for not protesting the Italian conquest of Ethiopia. In 1936 he sat�  isfied public opinion by procuring the abdication of Edward VIII, whose  desire to marry divorcee Wallis Simpson, Baldwin believed, threatened  the prestige of the monarchy.</p><p>Balearic Vba-le-'ar-ik\ Islands Spanish Islas Baleares Archipelago  (pop., 2001: 841,669), western Mediterranean Sea, constituting an autono�  mous community and province of Spain. It occupies an area of 1,927 sq  mi (4,992 sq km); its capital is Palma. The most important islands are  Majorca, Minorca, Ibiza, Formentera, and Cabrera. Long inhabited, the  islands were ruled by Carthage in the 6th century bc, by Rome from c.  120 bc, and by the Byzantine Empire from ad 534. Raided by the Arabs,  the area was conquered in the 10th century by the Umayyad dynasty at  Cordoba. It was reconquered by the Spanish and united with the kingdom  of Aragon in 1349. After territorial challenges in the 18th century by the  British, the islands came under Spanish rule in 1802. The present-day  economy is fueled by tourism.</p><p>baleen whale \bo-'len, 'ba-,len\ Any of about 13 species of cetaceans  in the suborder Mysticeti. They are distinguished by a specialized feed�  ing structure, the baleen, which strains plankton and small crustaceans  from the water. It consists of two horny plates attached to the roof of the  mouth. Each plate (as long as 12 ft, or 3.6 m, in the right whale) is com�  posed of parallel slats with fringes that mat together to form a sieve. Other  baleen whales are the blue, fin, gray, humpback, and sei whales and the  rorqual. Baleen was once used for corset stays and is still used in some  industrial brushes.</p><p>Balenciaga \bal-en-'thyag-3\, Cristobal (b. Jan. 21, 1895, Guetaria,  Spain�d. March 23, 1972, Valencia) Spanish-French fashion designer.  He studied dressmaking as a child and was inspired to become a coutu�  rier by a visit to Paris. By age 20 he had his own firm in San Sebastian.  Over the next 15 years Balenciaga became the leading couturier of Spain.  In 1937, when the Spanish Civil War disrupted his business, he moved  to Paris. For the next 30 years his collections featured sumptuously  elegant dresses and suits. Balenciaga helped popularize the trend toward  capes and flowing clothes without waistlines in the late 1950s as well as  the use of plastic for rainwear in the mid 1960s. He retired in 1968.</p><p>Balfour (of Whittingehame), Arthur James, 1 st Earl (b. July  25, 1848, Whittinghame, East</p><p>Lothian, Scot.�d. March 19, 1930,</p><p>Woking, Surrey, Eng.) British states�  man. The nephew of the marquess of  Salisbury, Balfour served in Parlia�  ment (1874-1911) and in his uncle�s  government as secretary for Ireland  (1887-91). From 1891 he was the  Conservative Party�s leader in Par�  liament and succeeded his uncle as  prime minister (1902-05). He helped  form the Entente Cordiale (1904). His  most famous action came in 1917  when, as foreign secretary (19lb-  19), he wrote the so-called Balfour  Declaration, which expressed official  British approval of Zionism. He  served as lord president of the coun�  cil (1919-22, 1925-29) and drafted  the Balfour Report (1926), which  defined relations between Britain  and the dominions expressed in the  Statute of Westminster.</p><p>Balfour Declaration (Nov. 2, 1917) Statement issued by the British  foreign secretary, Arthur James Balfour, in a letter to Lionel Walter Roth�  schild, a leader of British Jewry, as urged by the Russian Jewish Zionist  leaders Chaim Weizmann and Nahum Sokolow.

Located in the Lesser Sunda Islands, off the eastern coast of Java, it con�  stitutes, with minor adjacent islands, a province of Indonesia. The main  towns are Singaraja and Denpasar, the provincial capital. The island is  mountainous; its highest peak is Mount Agung (10,308 ft [3,142 m]).  Colonized by India in early times and supplemented by emigres from Java  in the 16th century, Bali is the remaining stronghold of Hinduism in the  Indonesian archipelago. Visited by the Dutch in the late 16th century, it  came under Dutch rule only in the late 19th century. It was occupied by  the Japanese in World War II and became part of Indonesia in 1950. Tour�  ism is now one of the mainstays of its economy.</p><p>Balinese People of the island of Bali, Indon. They differ from other  Indonesians in adhering to Hinduism, though their culture has been heavily  influenced by the Javanese. In Balinese villages each family lives in its  own compound, surrounded by earthen or stone walls; all villages have  temples and an assembly hall. Balinese religion fuses Hindu Shaivism with  Buddhism, ancestor cults (see ancestor worship), and belief in spirits and  magic. Marriage is often limited to members of the same kinship organi�  zation, and family relationships are reckoned through the male line.</p><p>Balkan League Vbol-konX (1912-13) Alliance of Bulgaria, Serbia,  Greece, and Montenegro, which fought the first Balkan War against the  Ottoman empire. Ostensibly created to limit Austrian power in the Bal�  kans, the league was actually formed at the instigation of Russia to expel  the Turks from the Balkans. The league disintegrated when its members  quarreled over the division of territorial spoils after their victory in the  first Balkan War.</p><p>Balkan Mountains Bulgarian Stara Planina Vsta-ra-.pla-ne-'naV  Mountain range, southeastern Europe. It extends east to west across cen�  tral Bulgaria from the Black Sea to the Serbian border; the highest point  is Botev Peak, at 7,795 ft (2,376 m). The range forms the major divide  between the Danube River in the north and the Maritsa River in the south.  It is crossed by about 20 passes (notably Shipka Pass), several railway lines,  and the Iskur River.</p><p>Balkan Wars (1912- 13) Two military conflicts that deprived the Otto�  man Empire of almost all its remaining territory in Europe. In the First Bal�  kan War, the Balkan League defeated the Ottoman Empire, which, under  the terms of the peace treaty (1913), lost Macedonia and Albania. The  Second Balkan War broke out after Serbia, Greece, and Romania quar�  reled with Bulgaria over the division of their joint conquests in Mace�  donia. Bulgaria was defeated, and Greece and Serbia divided up most of  Macedonia between themselves. The wars heightened tensions in the Bal�  kans and helped spark World War I.</p><p>Balkans or Balkan Peninsula Peninsula, southeastern Europe.  Located between the Adriatic Sea, the Mediterranean Sea, and the Aegean  and Black seas, it contains many countries, including Slovenia, Croatia,  Bosnia and Herzegovina, Macedonia, Serbia and Montenegro, Moldova,  Romania, and Bulgaria. From 168 bc to ad 107, part of the area was  incorporated into Roman provinces, including Epirus, Moesia, Pannonia,  Thrace, and Dacia. It was subsequently settled by Slavic invaders, Serbs,  Croats, Slovenes, and Slavonized Bulgars, the last of whom were pushed  into the Balkan region in the 6th century. It was gradually organized into  kingdoms, many of which were overrun by the Ottoman Empire in the  14th-15th century. The factional strife that occurred there from the early  20th century, provoking the continual breakups and regroupings of dif�  ferent states, introduced the word balkanize into English.</p><p>Balkhash, Lake or Lake Balqash Vbal-'kash\ Lake, southeastern  Kazakhstan. It is about 375 mi (600 km) long, with a maximum depth of  roughly 85 ft (25 m). Its chief feeder is the Ili River, which enters at the  west in a wide delta. Harsh climate affects its size greatly; its area has  varied from about 6,000 sq mi (15,500 sq km) to 7,300 sq mi (19,000 sq  km), depending on seasonal precipitation. It is frozen from November to  early April. Since the mid-20th century, industrial pollution has caused  severe ecological damage.</p><p>Ball, Lucille (Desiree) (b. Aug. 6, 1911, Celoron, near Jamestown,  N.Y., U.S.�d. April 26, 1989, Los Angeles, Calif.) U.S. actress and tele�</p><p>vision star. She performed in films  from 1933 and starred in a comedy  radio series from 1947. With her  bandleader husband, Desi Arnaz, she  created the very successful television  comedy series I Love Lucy (1951�</p><p>57) and later the Lucy-Desi Comedy  Hour (1957-60). After their divorce  in 1960, Ball appeared in The Lucy  Show (1962-68) and Here�s Lucy  (1968-74). With her red hair and  rasping voice and a comic persona  alternately brassy and feminine, she  was the preeminent female star of the  early decades of television.</p><p>ball bearing One of the two types  of rolling, or antifriction, bearings  (the other is the roller bearing). Its  function is to connect two machine  members that move relative to one another so that the frictional resistance  to motion is minimal. In many applications, one of the members is a  rotating shaft and the other a fixed housing. Each ball bearing has three  main parts: two grooved, ringlike races and a number of balls. The balls  fill the space between the two races and roll with negligible friction in the  grooves. The balls may be loosely restrained and separated by means of  a retainer or cage.</p><p>ballad Form of short narrative folk song. Its distinctive style crystal�  lized in Europe in the late Middle Ages as part of the oral tradition, and  it has been preserved as a musical and literary form. The oral form has  persisted as the folk ballad, and the written, literary ballad evolved from  the oral tradition. The folk ballad typically tells a compact tale with delib�  erate starkness, using devices such as repetition to heighten effects. The  modern literary ballad (e.g., those by W.H. Auden, Bertolt Brecht, and  Elizabeth Bishop) recalls in its rhythmic and narrative elements the tradi�  tions of folk balladry.</p><p>ballad opera English 18th-century comic opera in which songs and  musical interludes, usually consisting of existing popular tunes or opera  melodies with new words, are interspersed with spoken dialogue. The first  ballad opera, The Beggar�s Opera (1728), by John Gay and J.C. Pepusch  (1667-1752), was a sharply satirical work that became wildly popular and  led to numerous similar works. Ballad opera led directly to the German  singspiel and can be seen as the source of the modern musical.</p><p>ballade \ba-'lad\ One of several formes fixes in French lyric poetry and  song, cultivated particularly in the 14th�15th centuries. It consists of three  main stanzas having the same rhyme scheme plus a shortened final dedi�  catory stanza; all four stanzas have identical final refrain lines. The texts  were often solemn and formal, containing elaborate symbolism and clas�  sical references. Though present in the poetry of many ages and regions,  the ballade in its purest form was found only in France and England. Its  precursors can be found in the songs of the troubadours and trouveres.</p><p>Ballard \'bal-ord\, J(ames) G(raham) (b. Nov. 15, 1930, Shanghai,  China) British writer. Ballard spent four years of his childhood in a Japa�  nese prison camp, an experience he described in Empire of the Sun (1984;  film, 1987). His science fiction is often set in ecologically unbalanced  landscapes caused by decadent technological excess. His apocalyptic nov�  els, often shockingly violent, include Crash (1973; film, 1996), Concrete  Island (1974), and High Rise (1975). His later works include the short-  story collection War Fever (1990) and the novels The Kindness of Women  (1991) and Cocaine Nights (1998).</p><p>Ballard Vba-brd\, Robert D(uane) (b. 1942, Wichita, Kan., U.S.)  U.S. oceanographer and marine geologist. He grew up near San Diego,  Calif. As a marine scientist at the Woods Hole (Mass.) Oceanographic  Research Institution, he pioneered the use of deep-diving submersibles,  participated in the first manned exploration of the Mid-Atlantic Ridge, and  discovered warm water springs and their unusual animal communities in  the Galapagos Rift. He is best known for his dramatic discovery of the  wreck of the Titanic in 1985. Since then he has gone on to discover ships  lost in battle during World War II.</p><p>Ballesteros \,bal-9s- , ter-os\ / Seve(riano) (b. April 9, 1957, Pedrena,  Spain) Spanish golfer.

Known for his flamboyant and imaginative style of play, by the late 1990s  he had accumulated more than 70 wins in international tournaments.</p><p>ballet Theatrical dance in which a formal academic technique (the danse  d�ecole) is combined with music, costume, and stage scenery. Developed  from court productions of the Renaissance, ballet was renewed under  Louis XIV, who in 1661 established France�s Academie Royale de Danse,  where Pierre Beauchamp developed the five ballet positions. Early ballets  were often accompanied by singing and incorporated into opera-ballets  by composers such as Jean-Baptiste Lully. In the 18th century Jean-Georges  Noverre and Gasparo Angiolini separately developed the dramatic ballet  (;ballet d�action) to tell a story through dance steps and mime, a reform  echoed in Christoph Willibald Gluck�s music. Significant developments in  the early 19th century included pointe work (balance on the extreme tip  of the toe) and the emergence of the prima ballerina, exemplified by Marie  Taglioni and Fanny Elssler. In the late 19th and early 20th centuries, Rus�  sia became the centre of ballet production and performance, through the  work of innovators such as Sergey Diaghilev, Anna Pavlova, Vaslav Nijin�  sky, Marius Petipa, and Michel Fokine; great ballets were composed by Pyotr  Tchaikovsky and Igor Stravinsky. Since then, ballet schools in Great Brit�  ain and the U.S. have elevated ballet in those countries to Russia�s level  and greatly increased its audience. See also American Ballet Theatre; Bal�  let Russe de Monte Carlo; Ballets Russes; Bolshoi Ballet; New York City Bal�  let; Royal Ballet.</p><p>ballet position Any of the five positions of the feet fundamental to all  classical ballet. First codified by Pierre Beauchamp (1636-1705) in 1680,  the positions form the base from which a dancer achieves stability or  aplomb, the basic law of ballet. Fundamental to all the positions is the  turnout, or rotation of the dancer�s legs out from the hips, which creates  a firm basis for movement in any direction. Various positions of the arms  and hands (port de bras ) complete the figures.</p><p>Arabesque executed by Natalya Bessmertnova, with Nikolay Fadeychev, of the  Bolshoi Ballet; Swan Lake</p><p>NOVOSTI�SOVFOTO</p><p>Ballet Russe de Monte Carlo \ba-la-'rils-d3-mo n -ta- , kar-lo\ Ballet  company formed in Monte Carlo in 1932. The name derived from Sergey  Diaghilev� s Ballets Russes, which dissolved after his death in 1929. Under  Rene Blum and Col. W. de Basil, the company presented works by Leonide  Massine and George Balanchine and featured Alexandra Danilova, Andre  Eglevsky, and David Lichine. In 1938 clashes split the company into two  groups: the Original Ballet Russe (led by de Basil), which toured inter�  nationally before dissolving in 1948; and the Ballet Russe de Monte Carlo</p><p>(led by Massine), which toured mainly in the U.S. with Danilova, Alicia  Markova, and Maria Tallchief until 1963.</p><p>Ballets Russes \ba-la-'riEs\ Ballet company founded in Paris in 1909  by Sergey Diaghilev. Considered the source of modern ballet, the company  employed the most outstanding creative talent of the period. Its choreog�  raphers included Michel Fokine, Leonide AAassine, Bronislava Nijinska, and  George Balanchine, and among its dancers were Yekaterina Geltzer, Tamara  Karsavina, and Vaslav Nijinsky. Music was commissioned from compos�  ers such as Igor Stravinsky, Maurice Ravel, Darius Milhaud, Sergey Prokofiev,  and Claude Debussy, and ballets featured stage designs by artists Alexan�  dre Benois, Pablo Picasso, Georges Rouault, Henri Matisse, and Andre  Derain.</p><p>Ballinger Vbal-in-jorV Richard A(chilles) (b. July 9, 1858, Boones-  boro, Iowa, U.S.�d. June 6, 1922, Seattle, Wash.) U.S. secretary of the  interior (1909-11). As the reform mayor of Seattle, Wash. (1904-06), he  attracted national attention. In 1907 he was appointed commissioner of  the General Land Office, and in 1909 he became secretary of the interior.  During his two years in that post he sought to make public resources more  available for private exploitation. Implicated in a fraudulent Alaskan land-  claims scheme, he was cleared after a congressional investigation but  resigned in 1911. The episode split the Republicans between conserva�  tives led by Pres. William H.

The Greek version was basically a huge crossbow  fastened to a mount. The Roman ballista was powered by torsion derived  from two thick skeins of twisted cords through which were thrust two  separate arms joined at their ends by the cord that propelled the missile.  The largest could accurately hurl 60-lb (27-kg) weights up to about 500  yards (450 m).</p><p>ballistics Science of propulsion, flight, and impact of projectiles. Inter�  nal ballistics deals with propulsion of projectiles, such as within the bar�  rel of a gun or at a rocket launch. Guns and rocket engines convert chemical  energy of propellants into kinetic energy of projectiles. External ballistics  deals with projectile flight. The trajectory, or path, of a projectile is sub�  ject to the forces of gravity (see gravitation), drag, and lift. Terminal bal�  listics deals with the impact of projectiles on a target. Wound ballistics  deals with the mechanisms and medical implications of trauma caused by  bullets and explosively driven fragments, such as shrapnel.</p><p>balloon Large airtight bag filled with hot air or a lighter-than-air gas  such as helium or hydrogen that can rise and float in the atmosphere. Experi�  mental attempts may have begun by 1709, but not until 1783 did J.-M.  and J.-E. Montgolfier develop a fabric-bag balloon that would rise when  filled with hot air. Balloons provided military aerial observation sites in  the 19th century and were used in the 20th century by scientists such as  Auguste Piccard to gather high-altitude data. The first round-the-world  balloon flight was achieved in 1999 by Bertrand Piccard and Brian Jones.  See also airship.</p><p>ballooning Flying in a balloon in competition or for recreation. Sport  ballooning began in the early 20th century and became popular in the  1960s. The balloons used are of lightweight synthetic materials (e.g.,  polyester coated in aluminized mylar) and are filled with hot air or lighter-  than-air gas. Balloon races often involve tasks such as changing eleva�  tions or landing on or near a target. Competitions are regulated by the  Federation Aeronautique Internationale. The first transatlantic, transcon�  tinental, and transpacific balloon flights were achieved in 1978, 1980, and  1981, respectively. In 1997-98 international teams began competing to  become the first to balloon nonstop around the world. This feat was finally  accomplished in 1999 by the Swiss psychiatrist Bertrand Piccard (grand�  son of famed physicist and balloonist Auguste Piccard) and his British  copilot Brian Jones, who spent 19 days in the air.</p><p>Ballot Act (1872) British law that introduced the secret ballot for all  parliamentary and municipal elections.

In ancient times, it was part of Gedrosia. Alexander the Great  traversed it in 325 bc. It was included in the Bactrian kingdom, then was  ruled by Arabs from the 7th to the 10th century ad. It was ruled by Per�  sia for centuries, with the exception of a period when it belonged to the  Mughal Empire (1594-1638). It became a British dependency in 1876  and a British province of India in 1887. It was made part of Pakistan in  1947^-8 and was designated a separate province in 1970.

Because of its buoyancy (about twice that of cork), balsa has long been  used for making floats for lifelines and life preservers. Its resilience makes  it an excellent shock-absorbing packing material. Its insulating properties  make it a good lining material for incubators, refrigerators, and cold-</p><p>storage rooms. Because it combines lightness and high insulating power,  it is a valuable construction material for transportation containers for dry  ice (solidified carbon dioxide). It is also used in the construction of air�  plane passenger compartments and in model airplanes and boats.</p><p>balsam Aromatic resinous substance that flows from a plant, either  spontaneously or from an incision, and is used chiefly in medicinal prepa�  rations. Some of the more aromatic varieties are used in incense. Balsam  of Peru, a fragrant, thick, deep brown or black fluid used in perfumes, is  a true balsam, from a lofty leguminous tree, Myroxylon pereirae, native  to and introduced into Sri Lanka.

Born  in Paris to Polish parents, he was considered a child prodigy and was  encouraged by family friends including Pierre Bonnard, Andre Derain, and  Rainer Maria Rilke. Without formal training, he supported himself through  commissions for stage sets and portraits. He had his first one-man show  in 1934. In the midst of 20th-century avant-gardism, he explored the tra�  ditional categories of European painting: the landscape, the still life, the  subject painting, and the portrait. He presented ordinary moments of con�  temporary life on a grand scale and utilized traditional, Old Master paint�  ing techniques. Balthus is best known for his controversial depictions of  adolescent girls. His disturbing and erotic images and his carefully cul�  tivated persona made him an international cult figure. From 1961 to 1977  he served as director of the French Academy in Rome.</p><p>Baltic languages Branch of the Indo-European language family that  includes three attested languages, Lithuanian, Latvian, and Old Prussian.  They were or are spoken along the eastern and southeastern shore and  hinterlands of the Baltic Sea. Medieval chronicles report four other Baltic�  speaking peoples in the region, though by the 16th century these peoples  had been completely assimilated. Baltic has certain striking features in  common with Savic languages, though the deep divisions within Baltic  itself, among other factors, make the hypothesis of a common Balto-  Slavic protolanguage difficult to defend.</p><p>Baltic religion Ancient beliefs and practices of the Balts of Eastern  Europe. They are believed to give evidence of a common source with Vedic  and Iranian religion. The most important Baltic divinities were sky gods:  Dievs (the sky), Perkons (the thunderer), Saule (sun goddess), and Meness  (moon god). A forest divinity, the Mother of the Forest, was common to  all Baltic peoples and was differentiated into goddesses that personified  various aspects of nature. Destiny or luck was personified as the goddess  Laima, who determined a person�s fate at the moment of birth. The dead  were thought to revisit the world as good or evil spirits; evil was also  done by the devil. Veins, and by a werewolf-like creature known as Vilka-  cis or Vilkatas. The structure of the world, with the world tree at its cen�  ter, and the enmity between Saule and Meness are important themes.  Festivals marked the summer solstice, the harvest, marriages, and funer�  als. Worship was conducted at holy groves and small hills; excavations  have also revealed circular wooden temples.</p><p>Baltic Sea Sea, northern Europe. An arm of the Atlantic Ocean, con�  necting with the North Sea, it is about 1,000 mi (1,600 km) long, covers  an area of about 149,000 sq mi (386,000 sq km), and has a maximum  depth of about 1,500 ft (450 m). It receives the Vistula and Oder rivers  and many other rivers. It is enclosed by Denmark, Sweden, Finland, Esto�  nia, Latvia, Lithuania, Poland, Germany, and Russia. It has two large  arms, the Gulf of Bothnia and the Gulf of Finland. The modifying effect  of the North Atlantic Current is scarcely felt; its waters contain only about  one-fourth as much salt as the oceans, and it freezes readily.</p><p>Baltic States Republics of Lithuania, Latvia, and Estonia, situated on  the eastern shore of the Baltic Sea. The name has sometimes been used to  include Finland and Poland. They were created as independent states in  1917 from the Baltic provinces of Russia, the city of Kovno, and part of  the Polish department of Wilno (later Lithuania). With the aid of German  and Allied forces, the Baltic states repelled a Bolshevik invasion in 1919.  In 1940 they were forcibly occupied by the Soviet Union and incorpo-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Baltimore &#x25BA; Banbridge I 159</p><p>rated as constituent republics.

March 7, 1938, New York, N.Y., U.S.) U.S.  virologist. He received his doctorate from the Rockefeller Institute. He  and Howard Temin (1934-94), working independently, discovered an  enzyme that synthesizes DNA from RNA, the reverse of the usual pro�  cess. This enzyme, reverse transcriptase, has become an invaluable tool  in recombinant DNA technology. The research of Baltimore, Temin, and  Renato Dulbecco helped illuminate the role of viruses in cancer; the three  men shared a Nobel Prize in 1975. In 1990 Baltimore became president  of Rockefeller University; in 1997 he became president of the California  Institute of Technology.</p><p>Baltimore (of Baltimore), George Calvert, 1st Baron (b.</p><p>1578/79, Kipling, Yorkshire, Eng.�d. April 15, 1632) English colonial�  ist. He served in the House of Commons from 1621; charged with com�  municating the policy of James I, he was distrusted by Parliament. After  declaring himself a Roman Catholic (1625), he gave up his office and was  created Baron Baltimore, receiving land grants in Ireland. To assure the  prosperity of his New World holdings, he took his family to his New�  foundland colony in 1628. Because of conflict over his Catholicism and  the severe climate, he petitioned Charles I for a land grant in the Chesa�  peake Bay area. He died before the charter was granted, and his son Cecil  became proprietor of the colony of Maryland.</p><p>Baltimore City (pop., 2000: 651,154), north-central Maryland, U.S.  Located at the head of the Patapsco River estuary, 15 mi (24 km) above  Chesapeake Bay, it is Maryland�s largest city and economic hub. Estab�  lished in 1729, it was named after the Irish barony of Baltimore (seat of  the Calvert family, proprietors of the colony of Maryland). It became the  first U.S. Roman Catholic diocese in 1789. In 1827 the nation�s first rail�  road began operations there. In World War I, Baltimore began to develop  industrially, and it has since become a major seaport.</p><p>Baltimore and Ohio Railroad (B&amp;O) First steam-operated rail�  way in the U.S. to be chartered as a common carrier of freight and pas�  sengers (1827). The B&amp;O was established by Baltimore merchants to  foster trade with the West. By 1852 the railroad extended to Wheeling,  Va. (now W.V.), and in the next two decades it reached Chicago, Ill., and  St. Louis, Mo. The B&amp;O�s long-distance passenger trains were discon�  tinued in 1971 after Amtrak was established. Many of B&amp;O�s operations  were assumed by the CSX Corp. in 1980.</p><p>Baltimore Sun Daily newspaper published in Baltimore, Md., U.S. It  was begun as a four-page penny tabloid in 1837 by Arunah Shepherdson  Abell, a journeyman printer from Rhode Island. Known through much of  its history for its coverage of national and international news, the paper  was run by Abell�s family until 1910, when control passed to a group of  Baltimore businessmen, including H. Crawford Black. Members of  Black�s family were chairmen of the board until 1984. In 1986 the Sun  was acquired by the Times Mirror Company, which in turn was acquired  by the Tribune Company in 2000. Author H.L.

May 20,</p><p>1799, Tours, France�d. Aug. 18, 1850, Paris) French writer. Balzac  began working as a clerk in Paris at about age 16. An early attempt at a  business career left him with huge debts, and for decades he toiled inces�  santly to improve his worsening financial condition. In 1829 his novels  and stories began to achieve some success, and his early masterpieces  soon followed. In a vast series he collectively called The Human Com�  edy , eventually numbering some 90 novels and novellas, he sought to  produce a comprehensive picture of contemporary society by presenting  all the varieties of human nature. Among his masterpieces are Eugenie  Grandet (1833), Pere Goriot (1835), Lost Illusions (1837-43), A Harlot  High and Low (1843-47), and Cousin Bette (1846). His novels are notable  for their great narrative drive, their large casts of vital and diverse char�  acters, and their obsessive interest in and examination of virtually all  spheres of life. His best-known story collection is his Droll Stories, 3 vol.  (1832-37). His tumultuous life was one of mounting debts and almost  incessant toil, with frequent bouts of writing feverishly for 15 hours at a  stretch (his death has been attributed to overwork and excessive coffee</p><p>consumption). He is generally con�  sidered the major early influence on  realism, or naturalism, in the novel  and one of the greatest fiction writ�  ers of all time.</p><p>Bamako Vba-ma-.koX City pop.,</p><p>1996: metro area, 809,552), capital of  Mali.

The  genre�s originator and most noteworthy exponent was the Dutch painter  Pieter van Laer (1599-1642); the word derives from his nickname, II Bam-  boccio (�Little Clumsy One,� reflecting his physical deformity). Van Laer  arrived in Rome from Haarlem c. 1625 and influenced various other north�  ern European painters active in Rome. Their images depicting the lower  classes in humorous or grotesque ways were condemned by the leading  critics and painters. The bamboccianti (painters of bambocciati) influenced  the Dutch genre painters Adriaen Brouwer and Adriaen van Ostade.</p><p>bamboo Any of the tall, treelike GRASSes, found in tropical and subtropi�  cal to mild temperate regions, that make up the subfamily Bambusoideae,  family Poaceae (or Gramineae). Bamboos are giant, fast-growing grasses  with woody stems. A few species of the genus Arundinaria are native to  the southern U.S., where they form dense canebrakes along riverbanks and  in marshy areas. The woody, hollow aerial stems grow in branching clus�  ters from a thick rhizome, often forming a dense undergrowth that excludes  other plants. All parts of the bamboo are used, for purposes including food,  livestock fodder, fine-quality paper, construction materials, and medi�  cines. Bamboos also have ornamental use in landscape gardens.</p><p>Bambuti \ba-em-'bu-te\ or Mbuti A number of Pygmy peoples of the  Ituri Forest of eastern Congo (Kinshasa). Bambuti is a collective name for  four populations of Ituri Pygmies�the Sua (Asua), Aka, Efe, and Mbuti�  each of which has formed a loose economic and cultural interdependency  with an agricultural group. They average under 4 ft 6 in. (137 cm) in  height. Probably the earliest inhabitants of the region, they are nomadic  hunters and gatherers living in small groups of from 10 to 100. They have  no chiefs or formal councils of elders and believe in a benevolent forest  deity. Their music, complex in rhythm and harmony, is often accompanied  by dance or mime. Today they number in the tens of thousands.</p><p>banana Fruit of the genus Musa (family Musaceae), a gigantic herba�  ceous plant spread by rhizomes, and one of the most important food crops  of the world. The banana is consumed extensively throughout the trop�  ics, where it is grown, and is also valued in the temperate zone for its  flavour, nutritional value, and constant availability. Hundreds of varieties  are cultivated. Perhaps the most important species is the common banana,  M. sapientum. The ripe fruit is high in carbohydrates (mainly sugar),  potassium, and vitamins C and A, and it is low in protein and fat. Though  usually eaten fresh, bananas may also be cooked. The U.S. imports more  bananas than does any other country. See also plantain.</p><p>Banbridge District (pop., 2001: 41,392), Northern Ireland, established  in 1973.

Bands may be integrated  into a larger community or tribe. They generally exist in sparsely popu�  lated areas and possess relatively simple technologies; their habitats range  from the desert (Australian Aboriginals) to the African rainforest (Bambuti)  to the North American tundra (Kaska). Bands may occasionally coalesce  for broader community ceremonies, hunting, or warfare.

Ensembles of woodwind, brass, and percussion instruments originated in  15th-century Germany, taking on a particularly military role; these spread  to France, Britain, and eventually the New World. In the 15th�18th cen�  turies, many European towns had town musicians, or waits, who per�  formed especially for ceremonial occasions in wind bands often consisting  primarily of shawms and sackbuts (trombones). In the 18th�19th centu�  ries, the English amateur brass band, largely consisting of the many newly  developed brass instruments, took on the important nonmilitary function  of representing organizations of all kinds. In the U.S., Patrick Gilmore�s  virtuoso band became famous in the mid-19th century; his greatest suc�  cessor, John Philip Sousa, bequeathed a repertory of marches that has  remained very popular. The �big band,� under leaders such as Duke Elling�  ton and Count Basie, was central to American popular music in the 1930s  and �40s. In the rock band, unlike most other bands, stringed instruments  (electric guitars and electric bass) are paramount.</p><p>band theory In chemistry and physics, a theoretical model describing  the states of electrons in solid materials, which can have energy values only  within certain specific ranges, called bands. Ranges of energy between two  allowed bands are called forbidden bands. As electrons in an atom move  from one energy level to another, so can electrons in a solid move from an  energy level in one band to another in the same band or in another band. The  band theory accounts for many of the electrical and thermal properties of  solids and forms the basis of the technology of devices such as semicon�  ductors, heating elements, and capacitors (see capacitance).</p><p>Banda, Hastings (Kamuzu) (b. c. 1898, near Kasungu  [Malawi]�d.

It is a centre for the study and preserva�  tion of Sundanese culture and an educational centre.</p><p>bandwidth Measurement of the capacity of a communications signal.  For digital signals, the bandwidth is the data speed or rate, measured in  bits per second (bps). For analog signals, it is the difference between the  highest and lowest frequency components, measured in hertz (cycles per  second). For example, a modem with a bandwidth of 56 kilobits per sec�  ond (Kbps) can transmit a maximum of about 56,000 bits of digital data  in one second. The human voice, which produces analog sound waves,  has a typical bandwidth of three kilohertz between the highest and low�  est frequency sounds it can generate.</p><p>Banerjea \'ba-nor-je. Sir Surendranath (b. Nov. 10, 1848, Cal�  cutta, India�d. Aug. 6, 1925, Barrackpore, near Calcutta) Indian states�  man, one of the founders of modern India. As a young man, he attempted  unsuccessfully to serve in the Indian Civil Service, at the time virtually  closed to ethnic Indians. He then became a teacher and founded a college  in Calcutta (now Kolkata), which was later named for him. Banerjea  attempted to bring Hindus and Muslims together for political action, and  for 40 years he put forward a nationalist viewpoint in his newspaper, The  Bengalee. Twice elected president of the Indian National Congress, he  advocated for an Indian constitution on the Canadian model. He was  elected in 1913 to two legislative councils and later was knighted (1921);  in 1924 he was defeated by an independence candidate, whereupon he  retired to write his autobiography, A Nation in the Making (1925).</p><p>Banff National Park Park, southwestern Alberta, Canada. Estab�  lished as a natural reserve in 1885 and as Canada�s first national park in  1887, it lies on the eastern slopes of the Rocky Mountains and includes  mineral springs, ice fields, and glacial lakes, including Lake Louise. It  has been greatly expanded to its present area of 2,564 sq mi (6,641 sq  km). Banff is famed for its spectacular beauty, and visitors are so numer�  ous that it is now more a recreation than a conservation area. In 1984 it  was designated part of the Canadian Rocky Mountain Parks UNESCO  World Heritage site.</p><p>Bangalore Vbaq-g3-,lor\ City (pop., 2001: city, 4,301,326; metro, area,  5,701,446), capital of Karnataka state, southern India. It is a cultural  meeting place for speakers of the Kannada, Telugu, and Tamil languages.  Founded in the 16th century, it became a fief of the Indian ruler Hyder Ali  c. 1760 but was later taken by the British. It was the headquarters of the  British administration 1831-81, when it was restored to the raja of Mysore  (now Karnataka). Today, it is one of India�s largest cities and an indus�  trial and educational centre.</p><p>Banghdzl \ban-'ga-ze\ or Benghazi \ben-'ga-ze\ Coastal city (pop.,  1995 est.: 650,000), northeastern Libya. Located on the Gulf of Sidra, it  is Libya�s second largest city and was once its capital. Founded by Greeks  as Hesperides, it received from Ptolemy III the additional name Berenice  in honour of his wife. After the 3rd century ad it superseded Cyrene and  Barce as the chief city of the region. After its importance waned, it  remained a small town until it was extensively developed during the Ital�  ian occupation of Libya (1912-42). In World War II it suffered consid�  erable damage before being captured by the British in 1942. It is now an  administrative and commercial centre and the site of one of the world�s  largest desalinization plants.</p><p>Bangka or Banka Island, Bangka-Belitung province, west-central  Indonesia. Located off the eastern coast of Sumatra across the Bangka  Strait, it is separated from Billiton (Belitung) island by Gaspar Strait. Its</p><p>area is 4,375 sq mi (11,330 sq km); the chief town is Pangkalpinang. The  sultan of Palembang ceded Bangka to the British in 1812; they in turn  exchanged it with the Dutch in 1814 for property in India. Occupied by  Japan during World War II, it became part of Indonesia in 1949. Bangka  is one of the world�s chief tin-producing centres.</p><p>Bangkok Thai Krung Thep Vkrurj-'tepX City (pop., 2000: metro, area,  6,355,144), capital of Thailand. Lying 25 mi (40 km) above the mouth of  the Chao Phraya River, it is the country�s major port and also its cultural,  financial, and educational centre. It was established as the capital of Siam  (Thailand) in 1782 by King Rama I. Seized by the Japanese in World War  II, it subsequently suffered heavy Allied bombing. In 1971-72 it incor�  porated several outlying districts to form a single province-level metropo�  lis and has since experienced phenomenal growth. Throughout the city,  walled Buddhist temples and monasteries serve as focal points for its reli�  gious life.</p><p>Bangladesh officially People's Republic of Bangladesh</p><p>Country, south-central Asia. Area: 56,977 sq mi (147,570 sq km). Popu�  lation (2002 est.): 133,377,000. Capital: Dhaka. The vast majority of the</p><p>population are Bengali. Language: Bengali  (official). Religions: Islam (official; mainly  Sunni); also Hinduism. Currency: taka.  Bangladesh is generally flat, its highest  point reaching over 1,000 ft (305 m) above  sea level. The landscape is characterized by alluvial plains dissected by  numerous connecting rivers. The southern part consists of the eastern sec�  tor of the Ganges-Brahmaputra delta. The chief rivers are the Ganges  (there known as the Padma) and the Brahmaputra (or Jamuna), which unite  as the Padma. Though primarily agricultural, the country often is not self-  sufficient in food production. The monsoonal rains that occur from May to  October produce extreme flooding over much of Bangladesh, often caus�  ing severe crop damage and great loss of life. Cyclones in 1970 and 1991  killed some 300,000 and 140,000 Bengalis, respectively. Bangladesh is a  republic with one legislative house; its chief of state is the president and its  head of government the prime minister. In its early years Bangladesh was  known as Bengal. When the British left the subcontinent in 1947, the area  that was East Bengal became the part of Pakistan called East Pakistan.  Bengali nationalist sentiment increased after the creation of an indepen�  dent Pakistan. In 1971 violence erupted; some one million Bengalis were  killed, and millions more fled to India, which finally entered the war on the  side of the Bengalis, ensuring West Pakistan�s defeat. East Pakistan  became the independent country of Bangladesh. Little of the devastation  caused by the war has been repaired, and political instability, including the  assassination of two presidents, has continued.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>162 I Bangor &#x25BA; Banks</p><p>Bangor Town (pop., 1991: 52,437), seat of North Down district.

Its outlet  is the Luapula, a headstream of the Congo. It has three inhabited islands.  David Livingstone, the first European to visit the lake, died there in 1873.</p><p>Banja Luka \'ban-ya-Tu-ka\ City (pop., 1997 est.: 160,000), northeast�  ern Bosnia and Herzegovina. It was an important military centre under  the Turks and the seat (1583-1639) of the Bosnian territory governed by  a pasha. A battlefield between the Austrians and Turks in the 16th-18th  centuries, it played an important part in the 19th-century Bosnian upris�  ings against Turkey as well as in the revolts of the Serbs. It was a hub of  resistance in the Axis-dominated country of Croatia during World War II.  In 1992 it became the capital of the autonomous Serbian Republic of  Bosnia and Herzegovina. It was the site of much fighting during the Bos�  nian CONFLICT.</p><p>banjo Plucked stringed musical instrument of African origin. It has a  tambourine-like body, four or five strings, and a long fretted neck. The  fifth string (if present) is pegged at the fifth fret and acts primarily as a  drone plucked by the thumb. In its original form, the banjo had only four  strings and lacked frets. Slaves introduced the instrument to the U.S.,  where it was popularized in 19th-century minstrel shows and thence  exported to Europe. It has been an important American folk instrument,  especially in bluegrass, and it was used in early jazz.</p><p>Banjul \'ban-Jul\ formerly (1816-1973) Bathurst Seaport ( pop.,  1993: urban agglomeration, 270,540), capital of The Gambia. Located on  the Island of St. Mary in the Gambia River, it is the country�s largest city.  Founded by the British in 1816 to suppress the slave trade, it subsequently  became the capital of the British colony of Gambia. With The Gambia�s  independence in 1965, it became the national capital. Tourism is of  increasing importance, and Banjul serves as a transportation centre with  connections to the interior and to Senegal.</p><p>bank Institution that deals in money and its substitutes and provides other  financial services. Banks accept deposits and make loans and derive a  profit from the difference in the interest paid to lenders (depositors) and  charged to borrowers, respectively. They also profit from fees charged for  services. The three major classes of banks are commercial banks, investment  banks, and central banks. Banking depends entirely on public confidence  in the system�s soundness; no bank could pay all its depositors should  they simultaneously demand cash, as may happen in a panic. See also credit  union; Federal Reserve System; savings and loan association; savings bank.</p><p>Bank of Canada Canada�s central bank, established under the Bank  of Canada Act (1934). It was founded during the Great Depression to  regulate credit and currency. The Bank acts as the Canadian government�s  fiscal agent and has the sole right to issue paper money. It is directed by  the Canadian Ministry of Finance; all profits go to the Receiver General  of Canada.</p><p>Bank of England Central bank of Britain, headquartered in London.  Incorporated by act of Parliament in 1694, it soon became the largest and  most prestigious financial institution in England. It did not assume the  responsibilities of a central bank until the 19th century, and it was pri�  vately owned until 1946, when it was nationalized.</p><p>Bank of the United States Bank chartered in 1791 by the U.S. Con�  gress. It was conceived by Alexander Hamilton to pay off the country�s  debts from the American Revolution and to provide a stable currency. Its  establishment, opposed by Thomas Jefferson, was marked by extended  debate over its constitutionality and contributed significantly to the evo�</p><p>lution of pro- and anti-bank factions into the first U.S. political parties,  the Federalist Party and the Democratic-Republican Party. The national  bank played the unexpected but beneficial role of preventing private state  banks from overextending credit, a restriction that some nevertheless con�  sidered an affront to states' rights. Meanwhile, agrarian populists regarded  the bank as an institution of privilege and wealth and the enemy of democ�  racy and the interests of the common people. Antagonism over the bank  issue grew so heated that its charter could not be renewed in 1811. Criti�  cism of the bank reached its height during the administration of Pres.  Andrew Jackson, who led anti-bank forces in the long struggle known as  the Bank War. The bank�s charter expired in 1836. Its reorganization as  the Bank of the United States of Pennsylvania ended its regulation of pri�  vate banks.</p><p>bank rate See discount rate</p><p>Bank War Controversy in the 1830s over the existence of the Bank of  the United States, at that time the only national banking institution. The  first Bank of the United States, chartered in 1791 over the objections of  Thomas Jefferson, ceased in 1811 when Jeffersonian (Democratic) Repub�  licans refused to pass a new federal charter. In 1816 the second Bank of  the United States was created, with a 20-year federal charter. In 1829 and  again in 1830 Pres. Andrew Jackson made clear his constitutional objec�  tions to and personal antagonism toward the bank. He believed it con�  centrated too much economic power in the hands of a small moneyed elite  beyond the public�s control. Its president, Nicholas Biddle, with the sup�  port of Henry Clay and Daniel Webster, applied for a new charter in 1832,  four years before the old charter was due to expire, thus ensuring that the  bank would be an issue in the 1832 presidential election. Jackson vetoed  the recharter bill and won the ensuing election, interpreting his victory as  a mandate to destroy the bank. He forbade the deposit in the bank of gov�  ernment funds; Biddle retaliated by calling in loans, which precipitated a  credit crisis. Denied renewal of its federal charter, the bank secured a  Pennsylvania charter in 1836. Faulty investment decisions forced it to  close in 1841.</p><p>Banka See Bangka</p><p>Bankhead, Tallulah (Brockman) (b. Jan. 31, 1902, Huntsville,  Ala., U.S.�d. Dec. 12, 1968, New York, N.Y.)

Born to a prestigious family (her father became a prominent congress�  man), she made her Broadway debut in 1918 and achieved fame on the  London stage in The Dancer (1923). Her vivid presence and throaty voice  contributed to her singular performances in the hit plays The Little Foxes  (1939), The Skin of Our Teeth (1942), and Private Lives (1946). She made  films such as A Woman�s Law (1928) and Alfred Hitchcock�s Lifeboat  (1944) but remained primarily a stage performer. Her final stage appear�  ance was in The Milk Train Doesn �t Stop Here Anymore (1964).</p><p>bankruptcy Status of a debtor who has been declared by judicial pro�  cess to be unable to pay his or her debts. It also refers to the legal pro�  cess involved: the administration of an insolvent debtor�s property by the  court for the benefit of the debtor�s creditors. Filing by a debtor is called  voluntary bankruptcy; involuntary bankruptcy is declared by the court  upon petition by a creditor. The U.S. Bankruptcy Code makes four types  of relief available to bankrupt individuals or corporations: liquidation  (under Chapter 7), reorganization (Chapter 11), debt adjustment for a  family farmer (Chapter 12), and debt adjustment for an individual with a  regular income (Chapter 13). Municipalities may file under Chapter 9.  Generally, not all debts are paid in a bankruptcy. The court determines  which debts are to be repaid, and the debtor is typically granted a dis�  charge of the rest. See also insolvency.</p><p>Banks Island Island, Northwest Territories, Canada.

After studying at  Oxford, Banks inherited a fortune that allowed him to travel extensively,  collecting plant and natural history specimens. He outfitted and accom�  panied James Cook�s voyage around the world (1768-71). Particularly  interested in economic plants and their introduction from one country to  another, he was the first to suggest the identity of the wheat rust and bar�  berry fungus (1805); he was also the first to show that marsupial mam�  mals are more primitive than placental mammals. He served as president  of the Royal Society from 1778 to 1820, and, as unofficial director of Kew  Gardens, he transformed it into a major botanical institution.

The ceremony is usually accompanied by the words �I  baptize you in the name of the Father, and of the Son, and of the Holy  Spirit.� Indeed, Christians believe that after his resurrection, Jesus  appeared to his disciples and commanded them to baptize in the name of  the Father, Son, and Holy Spirit. In the teaching of St. Paul, it signifies  the wiping away of past sins and the rebirth of the individual into a new  life. Judaism practiced ritual purification by immersion, and the Gospels  report that John the Baptist baptized Jesus. Baptism was an important ritual  in the early church by the 1 st century, and infant baptism appeared by the  3rd century. Roman Catholic, Orthodox, and most Protestant churches  practice infant baptism. The Anabaptist reformers insisted on adult bap�  tism after a confession of faith; modern Baptists and the Disciples of Christ  also practice adult baptism.</p><p>Baptist Member of a group of Protestant Christians who hold that only  adult believers should be baptized and that it must be done by immersion.  During the 17th century two groups of Baptists emerged in England:  General Baptists, who held that Christ�s atonement applied to all persons,  and Particular Baptists, who believed it was only for the elect. Baptist  origins in the American colonies can be traced to Roger Williams, who  established a Baptist church in Providence, R.I., in 1639. Baptist growth  in the U.S. was spurred by the Great Awakening in the mid-18th century.  The 1814 General Convention showed divisions among U.S. Baptists over  slavery; a formal split occurred when the Southern Baptist Convention  was organized in 1845 and was confirmed when the Northern (American)  Baptist Convention was organized in 1907. African-American Baptist  churches provided leadership in the 1960s civil rights movement, notably  through the work of Martin Luther King. Baptist belief emphasizes the  authority of local congregations in matters of faith and practice; worship  is characterized by extemporaneous prayer and hymn-singing as well as  by the exposition of scripture in sermons.</p><p>baptistery or baptistry Domed hall or chapel, adjacent to or part of  a church, for the administration of baptism. By the 4th century, the bap�  tistery had assumed an eight-sided shape (eight in Christian numerology  being the symbol for a new life), as had the baptismal font within. The  font itself was set beneath a dome-shaped baldachin and encircled by col�  umns and an ambulatory (aisle), features first used by the Byzantines.

Simeon bar Kosba (d. ad 135)  Leader of an unsuccessful Jewish revolt against Roman rule in Palestine.  In 131 Hadrian forbade circumcision and built a temple to Jupiter on the  ruins of the Temple of Jerusalem. The Jews rebelled in 132, led by Sim�  eon bar Kosba, who, according to one story, was hailed as a messiah by  Akiba ben Joseph. He was called Bar Kokhba (�Son of the Star�), a mes�  sianic allusion drawn from the book of Numbers. His army captured Aelia  and inflicted heavy casualties, but Hadrian visited the battlefield and sum�  moned reinforcements, and the Romans retook Jerusalem. Bar Kokhba  was killed at Betar in 135, and the remnant of the Jewish army was soon  crushed, with total Jewish losses, according to the 3rd-century Roman  historian Dio Cassius, numbering 580,000. Surviving Jews were exiled  and barred from Jerusalem.</p><p>Bar Mitzvah X.bar-'mits-voX Jewish ritual celebrating a boy�s 13th birth�  day and his entry into the community of Judaism. It usually takes place  during a Sabbath service, when the boy reads from the Torah and may  give a discourse on the text. The service is often followed by a festive  Kiddush and a family dinner on the same day or next day. Reform Judaism  substituted confirmation of boys and girls for the Bar Mitzvah celebra�  tion after 1810, but many congregations restored the Bar Mitzvah in the  20th century. A separate ceremony for girls. Bat Mitzvah, has been insti�  tuted in Reform and Conservative Judaism.</p><p>Bara Vbar-oV, Theda orig. Theodosia Goodman (b. July 20,  1885?, Cincinnati, Ohio, U.S.�d. April 7, 1955, Los Angeles, Calif.) U.S.  film actress. She had a brief stage career before going to Hollywood. Her  first major picture, A Fool There Was (1915), was accompanied by a pub�  licity campaign, billing her as the daughter of a Middle Eastern potentate,  that made her an instant success. Establishing a sultry, exotic persona, she  became the prototype of the screen �vamp.� She made more than 40 films  within a few years, but her popularity soon declined, and she retired in  the 1920s.</p><p>Barabbas \bo-'ra-b3s\ In the New Testament, a prisoner or criminal freed  to please the mob before the crucifixion of Jesus. Described as a thief or  an insurrectionist, Barabbas is mentioned in all four Gospels. Following  the custom of setting free one prisoner chosen by popular demand before  Passover, Pontius Pilate suggested pardoning Jesus, but the crowd pro�  tested and demanded the release of  Barabbas. Pilate gave in and sent  Jesus to his death.</p><p>Barada Vbar-o-dsX River ancient  Chrysorrhoas River, western  Syria. It flows about 45 mi (72 km)  from the Anti-Lebanon Mountains  past Damascus. Throughout history,  channels have been cut at different  levels parallel to the main branch of  the river to divert its flow. The chan�  nels (of Nabataean, Aramaean, and,  especially, Roman origin) fan out as  they reach Damascus, irrigating a  large area. This system created the  site of Damascus, an artificial oasis  of extreme fertility.</p><p>Barak River See Surma River</p><p>Battistero (baptistery) San.

After graduating from Howard University and serving in the U.S. Air  Force, he joined the Beat movement and in 1961 published his first major  poetry collection. His play Dutchman (1964), produced off-Broadway,  explored the suppressed hostility of U.S. blacks toward the dominant  white culture. After the assassination of Malcolm X in 1965, Baraka  became involved in black nationalism and founded the Black Arts Rep�  ertory Theatre in Harlem. In 1974 he adopted a Marxist-Leninist philoso�  phy. He was appointed Poet Laureate of New Jersey in 2002.</p><p>barangay \,bar-9n-'gl\ Type of early Filipino settlement. The term was  derived from balangay, the sailboats that brought Malay settlers to the  Philippines from Borneo. Each boat carried a family group that estab�  lished a village. These villages, which sometimes grew to include 30-100  families, remained isolated from one another; the fact that no larger politi�  cal grouping emerged (except on Mindanao) facilitated the 16th-century  Spanish conquest. The Spanish retained the barangay as a unit of local  administration.</p><p>Barataria \,bar-9-'tar-e-9\ Bay Inlet of the Gulf of Mexico, southeast�  ern Louisiana, U.S. The bay is about 15 mi (24 km) long and 12 mi (19  km) wide, and its entrance is a narrow channel, navigable through con�  necting waterways into the Gulf Intracoastal Waterway system. The area  is noted for its shrimp industry and natural-gas and oil wells.

Largely cov�  ered by a layer of coral, Barbados is low and flat except in its north-central  part; its highest point is Mount Hillaby, at 1,115 ft (340 m). There is little  surface water. The island is almost encircled by coral reefs. Bridgetown is  its only seaport. The economy is based on tourism and sugar, while the off�  shore financial sector is growing. Barbados is a constitutional monarchy  with two legislative houses; its chief of state is the British monarch, rep�  resented by a governor-general, and the head of government is the prime  minister. The island was probably inhabited originally by Arawak and  later by Carib Indians. Spaniards may have landed by 1518, and by 1536  they had apparently wiped out the Indian population. Barbados was settled</p><p>by the English in the 1620s. Slaves were brought in to work the sugar  plantations, which were especially prosperous in the 17th�18th century.  The British Empire abolished slavery in 1834, and all the Barbados slaves  were freed by 1838. In 1958 Barbados joined the West Indies Federation.  When the latter dissolved in 1962, Barbados sought independence from  Britain, which it gained in 1966.</p><p>Barbara, Saint (d. 200; feast day December 4) Early Christian mar�  tyr and patroness of artillerymen. She was the daughter of a pagan, Dios-  corus, who kept her guarded to protect her beauty and virginity. When she  converted to Christianity he became enraged and took her to the Roman  prefect, who ordered her to be tortured and beheaded. Her father per�  formed the execution himself, and on the way home he was struck by  lightning and reduced to ashes. Barbara was a popular saint during the  Middle Ages and was invoked for aid in thunderstorms. She was dropped  from the church calendar in 1969.</p><p>Barbarossa \,bar-b9-'ra-s9\ orig. Khidr later Khayr al-DTn (d.</p><p>1546) Greek Turkish pirate and admiral in the service of the Ottoman  Empire. He and his brother c Aruj, sons of a Turk from Lesbos, hated the  Spanish and Portuguese for their attacks on North Africa and took up  piracy on the Barbary Coast in hopes of seizing an African domain for  themselves. When c Aruj was killed in 1518, Khidr took the title Khayr  al-Dln. He offered allegiance to the Ottoman sultan and in return received  military aid that enabled him to capture Algiers in 1529. Appointed admi�  ral in chief of the Ottoman Empire (1533), he conquered all of Tunisia.  Emperor Charles V captured Tunis in 1535, but Khayr al-Dln defeated his  fleet at the Battle of Preveza (1538), securing the eastern Mediterranean  for the Turks for 33 years. His red beard was the source of the epithet  Barbarossa, used by Europeans.</p><p>Barbary Coast Mediterranean coastal region. North Africa. It extends  from Egypt to the Atlantic Ocean. Once part of Roman Africa, the region  was overrun by Vandals in the 5th century ad. Reconquered by the East�  ern Roman Empire (Byzantine Empire) c. ad 533, it was overcome by Arabs  during the 7th century and was eventually broken up into the independent  Muslim polities known collectively as the Barbary states (Morocco, Alge�  ria [Algiers], Tunisia [Tunis], and Libya [Tripoli]). For centuries the coast  was notorious as a haven for pirates, who ravaged shipping and collected  tribute from European states. After the U.S. war with Tripoli (see Tripol�  itan War), the U.S. expedition to Algiers (1815), and the bombardment  of Algiers by the British (1816), the pirates ceased exacting tribute.</p><p>Barbary macaque Tailless, terrestrial monkey ( Macaca sylvana)  found in groups in Algeria and  Morocco and on the Rock of Gibral�  tar. It is about 24 in. (60 cm) long and  has yellowish brown fur and a bald,  pale pink face. Lacking a tail, this  macaque has often been incorrectly  called an ape. It is the only wild  monkey in Europe and may have  arrived in medieval times, taken  westward during the Muslim Arab  territorial expansion. According to  legend, British dominion over  Gibraltar will end when the Barbary  macaque departs.</p><p>Barber, Red orig. Walter Lanier Barber (b. Feb. 17,1908, Colum�  bus, Miss., U.S.�d.

After graduation in 1934,  he devoted himself to composition. Barber�s style, frequently lyrical and  neo-Romantic, proved highly attractive to the public. His works include  the popular Adagio for Strings (1936), two Essays for Orchestra (1937,  1942), the opera Vanessa (1957, Pulitzer Prize), and a Piano Concerto  (1962, Pulitzer Prize).</p><p>Barbary macaque (Macaca sylvana).</p><p>TOM MCHUGH/PHOTO RESEARCHERS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>166 I barberry &#x25BA; Bard College</p><p>barberry Any of the almost 500 species of thorny evergreen or decidu�  ous shrubs constituting the genus  Berberis. The genus is the largest  and most important group in the fam�  ily Berberidaceae, of the buttercup  order. Most barberries are native to  the northern temperate zone, particu�  larly Asia. Barberry bushes have yel�  low wood and yellow flowers. The  fruit of several species is made into  jellies. Other members of the same  family include heavenly bamboo  (Nandina domestica), an indoor pot�  ted plant; mayapple ( Podophyllum  peltatum), a woodland wildflower;</p><p>Epimedium, a ground cover; and Oregon grape ( Mahonia ), a genus of  broad-leaved evergreen shrubs.</p><p>barbershop quartet Popular vocal ensemble consisting of four unac�  companied male voices.

(29 cm) tall, with the figure of an adult woman that was introduced in 1959  by Mattel, Inc., a southern California toy company. Ruth Handler, who  cofounded Mattel with her husband, Elliot, spearheaded the introduction  of the doll. Since the 1970s, Barbie has been criticized for materialism  (amassing cars, houses, and clothes) and unrealistic body proportions. Yet  many women who had played with the doll as girls credit Barbie with pro�  viding an alternative to restrictive 1950s gender roles. Today the doll has  come to symbolize consumer capitalism and is a global brand, with key  markets in Europe, Latin America, and Japan. Barbie never caught on in  the Muslim world, however. In 1995 Saudi Arabia stopped its sale because  it violated the Islamic dress code. Similar dolls, complete with hijabs  (head coverings), were eventually marketed to Muslim girls.</p><p>Barbie, Klaus (b. Oct. 25, 1913, Bad Godesberg, Ger.�d. Sept. 25,  1991, Lyon, France) Nazi leader. As head of the Gestapo in Lyon, France  (1942-44), he pursued members of the French Resistance and promoted  the torture and execution of thousands of prisoners. After World War II  he was seized by U.S. authorities in Germany, who recruited him for  counterintelligence work (1947-51) and then moved him and his family  to Bolivia. He lived there as a businessman from 1951 until he was extra�  dited to France in 1983 to stand trial. Throughout his trial �the Butcher  of Lyon� remained unrepentant and proud of his service to the Nazis. Held  responsible for the death of some 4,000 persons and the deportation of  some 7,500 others, he was sentenced to life imprisonment.</p><p>barbiturate \bar-'bi-cli3-r3t\ Any of a class of heterocyclic compounds  based on the parent structure, uric acid, and used in medicine. They  depress the central nervous system, acting particularly on certain parts of</p><p>the brain, though they tend to depress the functioning of all the body�s  tissues. Long-acting barbiturates (e.g., barbital and phenobarbital) are  used to treat epilepsy. Intermediate ones (e.g., amobarbital) are used to treat  insomnia, short-acting ones (e.g., pentobarbital) to overcome difficulty in  falling asleep (one aspect of insomnia), and ultra-short-acting ones (e.g.,  thiopental sodium) to induce unconsciousness in surgical patients before  administration of other anesthetics. Prolonged use of barbiturates may lead  to addiction. Sudden withdrawal can be fatal; addicts must be weaned  from the drug under medical supervision. Overdoses can result in coma  and even death; barbiturates are particularly dangerous, even at normal  doses, when combined with alcoholic beverages.</p><p>Barbizon \,bar-b3- , zon\ school Group of 19th-century French land�  scape painters. They were part of a larger European movement toward  naturalism that made a significant contribution to realism in French land�  scape painting.

It  is said to have been founded in the 3rd century bc by the Carthaginians  or the Phoenicians, and it was later ruled by the Romans and Visigoths.  It was captured by the Moors c. ad 715, but it was retaken by the Franks  under Charlemagne in 801 and made the capital of the Spanish March  (Catalonia). After Catalonia united with Aragon in 1137, Barcelona  became a flourishing commercial centre and the rival of Italian ports. In  the 19th century it was a cauldron for radical social movements and Cat�  alan separatism. It was the loyalist capital in 1937-39 during the Spanish  Civil War; its capture by Francisco Franco brought the collapse of Cata�  lan resistance and Catalonia�s reintegration into Spain.

Oct. 24,  1938, Giistrow) German sculptor, graphic artist, and writer. After study�  ing in Hamburg, Dresden, and Paris, he became the outstanding sculptor  of the Expressionist movement, achieving a rough-hewn quality by pre�  ferring wood, the material used in late Gothic sculpture. Even when he  worked with other, more contemporary materials, he often emulated the  raw quality of wood sculpture to achieve a more brutal effect. He achieved  fame in the 1920s and �30s with the execution of several war memorials  for the Weimar Republic. Barlach also wrote Expressionist plays, which  he illustrated with woodcuts and lithographs. His studio at Giistrow was  opened posthumously as a museum.</p><p>barley Cereal plant of the genus Hordeum, in the family Poaceae (or  Gramineae), and its edible grain. The three cultivated species are H. vul-  gare, H. distichum, and H. irregulare. Barley is adaptable to a greater  range of climate than any other cereal. About half of the world�s crop is  used as livestock feed, the rest for human food and for malting. Most beer  is made from malted barley, which is also used in distilled beverages (see  malt). Barley has a nutlike flavour and is high in carbohydrates, with  moderate quantities of protein, calcium, and phosphorus. Barley flour is  used to make unleavened bread and porridge.

The first notable Barmakid,  Khalid ibn Barmak (d. 781/782), helped establish the 'Abbasid caliphate;  he became governor of Tabaristan and later Fars. His son Yahya (d. 805)  and grandsons al-Fadl (d. 808) and Ja'far (d. 803) held power as viziers  but died in prison or were executed in a reversal of fortune, largely  because their excessive power, wealth, and liberalism led the caliphs to  see them as threats.</p><p>Barmen, Synod of Meeting of German Protestant leaders at Barmen  in May 1934 to organize Protestant resistance to Nazism.

In 1902 he made a fortune with his invention of the antiseptic  Argyrol. After building a mansion in Merion, Pa., in 1905, he began to  collect art seriously, amassing some 180 paintings by Pierre-Auguste  Renoir, 66 by Paul Cezanne, 35 by Pablo Picasso, and an extraordinary col�  lection of 65 works by Henri Matisse. The Barnes Foundation, housed in  quarters next to his Merion home, was chartered on Dec. 4, 1922, and  opened in 1925. The 22-room structure displayed his collection in a highly  personal manner that eschewed standard museum practice. The founda�  tion also was intended to promote art education by providing art classes  and by establishing a publishing program. (Barnes himself wrote and  coauthored a number of books on art.) In 1961, after extensive litigation,  his galleries were opened to the public.</p><p>Barnes, Djuna (b. June 12, 1892, Cornwall-on-Hudson, N.Y., U.S.�d.  June 18?, 1982, New York, N.Y.) U.S. writer.

Born to a wealthy fam�  ily, Barnet took up the saxophone as a child and eventually performed on  tenor, alto, and soprano. His was among the first of the big bands to be  racially integrated, and his unabashed admiration for Duke Ellington and  Count Basie resulted in an effective synthesis of their styles.

He executed altarpieces and devotional paintings in  a style characterized by subtle colour harmonies and warmth of feeling.  His patrons included the duke of Urbino and Emperor Rudolf II (1552�  1612), and he received commissions from the cathedrals of Genoa and  Perugia. His famous works include the Deposition (1567-69) and the  Madonna del Popolo (1579). A prolific draftsman, he was one of the first  artists to use coloured chalks.

His most ambitious project was a long cycle  of works about a 19th-century insurgent and his era. He wrote almost 100  novels, including Zalacain el aventurero (1909). Because of his anti-  Christian views, stubborn insistence on nonconformity, and somewhat  pessimistic tone, he never achieved great popularity. He is considered the  foremost Spanish novelist of his time.</p><p>barometer Device used to measure atmospheric pressure. Because atmo�  spheric pressure changes with distance above or below sea level, a barom�  eter can also be used to measure altitude. In the mercury barometer,  atmospheric pressure balances a column of mercury, the height of which  can be precisely measured. Normal atmospheric pressure is about 14.7 lb  per square inch, equivalent to 30 in. (760 mm) of mercury. Other liquids  can be used in barometers, but mercury is the most common because of  its great density. An aneroid barometer indicates pressure on a dial using  a needle that is mechanically linked to a partially evacuated chamber,  which responds to pressure changes.</p><p>barometric pressure See atmospheric pressure</p><p>baron Title of nobility, ranking in modern times immediately below a  viscount or a count (in countries without viscounts).

It had its origins in the  Counter-Reformation, when the Catholic Church launched an overtly emo�  tional and sensory appeal to the faithful through art and architecture.  Complex architectural plan shapes, often based on the oval, and the  dynamic opposition and interpenetration of spaces were favoured to  heighten the feeling of motion and sensuality. Other characteristic quali�  ties include grandeur, drama and contrast (especially in lighting), curva�  ceousness, and an often dizzying array of rich surface treatments, twisting  elements, and gilded statuary. Architects unabashedly applied bright  colours and illusory, vividly painted ceilings. Outstanding practitioners in  Italy included Gian Lorenzo Bernini, Carlo Maderno (1556-1629),  Francesco Borromini, and Guarino Guarini (1624-83).

The late Baroque style is  often referred to as Rococo or, in Spain and Spanish America, as Chur-  RIGUERESQUE.</p><p>Baroque period (17th�18th century) Era in the arts that originated in  Italy in the 17th century and flourished elsewhere well into the 18th cen�  tury. It embraced painting, sculpture, architecture, decorative arts, and  music. The word, derived from a Portuguese term for an irregularly  shaped pearl and originally used derogatorily, has long been employed to  describe a variety of characteristics, from dramatic to bizarre to over�  decorated. The style was embraced by countries absorbed in the Counter-  Reformation; artworks commissioned by the Roman Catholic church were  overtly emotional and sensory. The period�s most notable practitioners  were Annibale Carracci (see Carracci family), Caravaggio, and Gian  Lorenzo Bernini. A spectacular example of the Baroque arts is the Palace  of Versailles. In music, the Baroque era is usually considered to extend  from c. 1600 to c. 1750, when such significant new vocal and instrumen�  tal genres as opera, oratorio, cantata, sonata, and concerto were intro�  duced and such towering composers as Claudio Monteverdi, J.S.

After the war he was recalled to active ser�  vice as senior captain of the new U.S. Navy. He was often called the  �Father of the Navy� because he trained many future naval officers.</p><p>Barrymore family U.S. theatrical family. Maurice Barrymore (orig.  Herbert Blythe; 1847-1905) made his stage debut in London before mov�  ing to New York City (1875), where he adopted Barrymore as his stage  name. He joined Augustin Daly�s company and in 1876 married Georgi-  ana Drew, of the theatrical Drew family. Their eldest child, Lionel Barry�  more (orig. Lionel Blythe; 1878-1954), became a leading Broadway actor  in plays such as Peter Ibbetson (1917) and The Copperhead (1918), then  moved to Hollywood in 1926, where he appeared in films such as A Free  Soul (1931, Academy Award) and Grand Hotel (1932). Famous as a char�  acter actor, he made some 200 films, including 15 Dr. Kildare pictures.  His sister Ethel Barrymore (orig. Ethel Blythe; 1879-1959) appeared in  London in Peter the Great (1898) and on Broadway in Captain Jinks of  the Horse Marines (1901). She opened the New York theatre named for  her in 1928 in The Kingdom of God and later starred in The Corn Is Green  (1940). She appeared in more than 30 films, including None but the Lonely  Heart (1944, Academy Award) and The Spiral Staircase (1946). Their  brother John Barrymore (orig. John Blythe; 1882-1942) was acclaimed  in plays such as Justice (1916), Richard III (1920), and especially Ham�  let (1922). His films include Dr. Jekyll and Mr. Hyde (1920) and Dinner  at Eight (1933). An alcoholic, he was known for his flamboyant behav�  iour. John�s granddaughter Drew Barrymore (b. 1975) first won notice at  age seven in the film E.T. (1982).</p><p>barter Direct exchange of goods or services without the use of money  or any other intervening medium of exchange.

Barth grew up on Maryland�s eastern  shore, the locale of much of his writing, and from 1953 he taught prin�  cipally at Johns Hopkins University. Apart from the experimental pieces  in Lost in the Funhouse (1968), his best-known works are the novels The  Floating Opera (1956), The End of the Road (1958), The Sot-Weed Fac�  tor (1960), Giles Goat-Boy (1966), and The Tidewater Tales (1987), most  of which play with and parody traditional narrative forms, combining  philosophical depth with biting satire and boisterous, often bawdy  humour. In 2001 he published the experimental novel Coming Soon!!!: A  Narrative, which was not well received.</p><p>Barth \'bart\, Karl (b. May 10, 1886, Basel, Switz.�d. Dec. 9/10, 1968,  Basel) Swiss theologian. He studied at the Universities of Berlin, Tubin�  gen, and Marburg, and in 1911-21 he was a pastor at Safenwil, Switz.  The tragedy of World War I made him question the liberal theology of his  teachers, rooted in post-Enlightenment ideas. With The Epistle to the  Romans (1919) he inaugurated a radical turnaround in Protestant thought,  initiating a trend toward neoorthodoxy. The work led to his appointment  as professor at Gottingen (1921), Munster (1925), and Bonn (1930). He  was a founder of the Confessing Church, which opposed the Nazi regime;  when his refusal to take the oath of allegiance to Adolf Hitler cost him his  chair at Bonn, he returned to Basel. He spoke at the opening of the World  Council of Churches in 1948 and visited Rome following the Second Vat�  ican Council.</p><p>Barthelme Vbart-ol-meV, Donald (b.

Nov. 12, 1915, Cherbourg,  France�d. March 25, 1980, Paris) French social and literary critic. His  early books examined the arbitrariness of the constructs of language and  applied similar analyses to popular-culture phenomena. He analyzed mass  culture in Mythologies (1957). On Racine (1963) set off a literary furor,  pitting him against more traditional French literary scholars. His later  contributions to SEMIOTICS included the even more radical S/Z (1970); The  Empire of Signs (1970), his study of Japan; and other significant works  that brought his theories wide (if belated) attention in the 1970s and  helped establish structuralism as one of the leading intellectual movements  of the 20th century. In 1976 he became the first person to hold the chair  of literary semiology at the College de France.</p><p>Bartholdi \bar-'tol-de\, Frederic-Auguste (b. April 2, 1834, Col�  mar, Alsace, Fr.�d.

March 25, 1881, Nagyszentmiklos, Hung.,  Austria-Hungary�d. Sept. 26, 1945, New York, N.Y., U.S.) Hungarian  composer, pianist, and ethnomusicologist. He developed a superb piano  technique at an early age. In 1904 he set about researching Hungarian  folk music, having discovered that the folk-music repertory generally  accepted as Hungarian was in fact largely urban Roma (Gypsy) music  (see Rom). His fieldwork with the composer Zoltan KodAly formed the  basis for all later research in the field, and he published major studies of  Hungarian, Romanian, and Slovakian folk music. He worked folk themes  and rhythms into his own music, achieving a style that was at once nation�  alistic and deeply personal. He also toured widely as a virtuoso pianist.  In 1940 he immigrated to the U.S., where he was inadequately recognized.  His works include the opera Bluebeard�s Castle (1911), six celebrated  string quartets (1908-39), the didactic piano set Mikrokosmos (1926-39),  Sonata for Two Pianos and Percussion (1937), Concerto for Orchestra  (1943), and three piano concertos (1926, 1931, 1945).</p><p>Bartolome de Cardenas See Bartolome Bermejo</p><p>Bartolomeo V.bar-to-lo-'ma-oV, Fra orig.

In 1852 she established a free school in Bordentown, N.J.,  that soon became so large that the townsmen would no longer allow a  woman to run it. After resigning her post, she was employed by the U.S.  Patent Office in Washington, D.C. (1854-57, 1860). During the Ameri�  can Civil War she organized the distribution of medicine and supplies for  soldiers wounded in the first Battle of Bull Run. She gained permission  to pass through battle lines to distribute supplies, search for the missing,  and nurse the wounded, becoming known as the �angel of the battlefield.�  In 1865, at the request of Pres. Abraham Lincoln, she set up a bureau of  records to aid in the search for missing men. While in Europe for a rest,  she helped with relief work for victims of the Franco-Prussian War (1870-  71) and became associated with the International Red Cross. In 1881 she  founded the American Red Cross. She lobbied Congress to sign the  Geneva Convention (see Geneva Conventions), which provided for the  treatment of the sick and wounded in battle and the proper handling of  prisoners of war. She wrote the U.S. amendment to the constitution of the  Red Cross, which provides for the distribution of relief not only in war  but also during natural disasters.

It has been understood as a  physical barrier between heaven and hell and as a moral prohibition by  God. The term is used elsewhere in the Qur�an to describe a barrier  between two seas, one saltier than the other, whose waters meet but do  not mix.

It was once thought to have  been invented in 1839 by Abner  Doubleday in Coopers town, N.Y.,  but it is more likely that baseball  developed from an 18th-century  English game called rounders that  was modified by Alexander Cart�  wright. The first professional asso�  ciation was formed in 1871; in 1876  it became the National League. Its  rival, the American League, was founded in 1900, and since 1903 (except  in 1904 and 1994) the winning teams of each league have played a post�  season championship known as the World Series. The Baseball Hall of  Fame is located in Cooperstown. Professional baseball leagues also exist  in several Latin American countries. The champions of leagues in the  Dominican Republic, Mexico, Puerto Rico, and Venezuela compete in the  Caribbean Series each February.

The original Bessemer converter was not  effective in removing the phosphorus from iron made from the high-  phosphorus ores common in Britain and Europe. The invention of the  basic process in England by Sidney G. Thomas (1850-1885) and Percy  Gilchrist overcame this problem; the Thomas-Gilchrist converter was  lined with a basic material such as burned limestone rather than an acid  siliceous material. The introduction of the basic Bessemer process in 1879  made it possible for the first time for such high-phosphorus ore to be used  for making steel.</p><p>Basic Input/Output System See BIOS</p><p>basic oxygen process Steelmaking method in which pure oxygen is  blown through a long, movable lance into a bath of molten blast-furnace  iron and scrap, in a steel furnace with a refractory lining called a con�  verter. The oxygen initiates a series of heat-releasing reactions, including  the oxidation of such impurities as silicon, carbon, phosphorus, and man�  ganese; carbon dioxide is released, and the oxidation products of the other  impurities form molten slag that floats on the molten steel. The advan�  tages of using pure oxygen instead of air in refining iron into steel were  recognized as early as the 1850s (see Bessemer process), but the process  could not be commercialized until the late 1940s, when cheap, high-purity  oxygen became available. Within 40 years it had replaced the open-hearth  process and was producing more than half of all steel worldwide.

Aug. 29, 886) Byzantine emperor (867-86) and founder of  the Macedonian dynasty. Born into a peasant family in Macedonia, he  won employment in official circles in Constantinople and was made cham�  berlain by the reigning emperor, Michael III. He became coemperor with  Michael in 866 and murdered him the next year. Basil won victories  against Muslim forces along the eastern borders of Asia Minor and  asserted control over Slavs in the Balkans. He gained ground in southern  Italy but lost Syracuse (878) and other key cities in Sicily to the Muslims.  He also formulated the Greek legal code known as the Basilica. In later  life Basil showed signs of madness.</p><p>Basil II known as Basil Bulgaroctonus \,bul-g3-'rak-t9-n3s\  ("Slayer of the Bulgars") (b. 957/958�d. Dec. 15, 1025) Byzantine  emperor (976-1025). Crowned coemperor with his brother in 960, he had  to exile the grand chamberlain (985) and defeat rival generals (989) in  order to gain the authority to rule. Basil became one of the strongest Byz�  antine emperors, winning territory in the Balkans, Mesopotamia, Armenia,  and Georgia. He was noted for his victory (1014) in the war with Bulgaria,  which ended with his blinding all the soldiers in the defeated Bulgarian  army. He increased his domestic authority by attacking the landed inter�  ests of the military aristocracy and of the church. Because Basil left no  able successor, the gains of his rule were soon undone.</p><p>Basil the Great, Saint (b. ad 329, Caesarea Mazaca, Cappadocia� d.  Jan. 1, 379, Caesarea; Western feast  day January 2; Eastern feast day  January 1) Early church father. Born  into a Christian family in Cappado�  cia, he studied at Caesarea, Constan�  tinople, and Athens and later  established a monastic settlement on  the family estate at Annesi. He  opposed Arianism, which was sup�  ported by the emperor Valens and his  own bishop Dianius, and organized  resistance to it after 365. He suc�  ceeded Eusebius as bishop of Cae�  sarea in 370. He died shortly after  Valens, whose death in battle opened  the way for the victory of Basil�s  cause. More than 300 of his letters  survive; several of his Canonical  Epistles have become part of canon  law in Eastern Orthodoxy.</p><p>basilica Originally a secular pub�  lic building in ancient Rome, typically a large rectangular structure with  an open hall and a raised platform at one or both ends. In one type, the  central hall was flanked by side aisles set off by colonnades, and the raised  platform was enclosed by an apse. The early Christians adopted this type  for their churches. In the typical early Christian basilica, the columns  separating the nave from the lower side aisles carried either arches or  entablatures, above which rose clerestory walls that supported the roof.  The long nave came to be crossed just before the apse by a shorter tran�  sept, creating the cross-shaped plan that remains a standard church form  to the present. �Basilica� is also a title of honor given to a Roman Catho�  lic or Greek Orthodox church distinguished by its antiquity or its role as  an international center of worship.

According to Clement of Alexandria, Basil�  ides claimed to base his teaching on a secret tradition of Peter the Apostle.  He wrote psalms, odes, commentaries on the Gospels, and his own gos�  pel. Fragments of these writings and varying accounts by Clement, St.  Irenaeus, and others suggest that his system of belief included elements  from Neoplatonism as well as the New Testament. The school survived  in Egypt until the 4th century.</p><p>Baskerville, John (b. Jan. 28,</p><p>Eng.�d.

His editions of the  Latin classics, John Milton�s poems  (1758), and a folio Bible (1763) are  characterized by clear and careful  presswork rather than ornament;  they are among the finest examples  of the art of printing. He served as  printer to Cambridge University  (1758-68), and he created the widely  used Baskerville typeface, which is  still used and prized for its clarity  and balance.</p><p>basketball Court game between  two teams of five players. They score  by tossing, or �shooting,� an inflated  ball through a raised hoop, or �bas�  ket,� located in their opponent�s end  of the court. A goal is worth two  points, three if shot from outside a  specified limit. A player who is  fouled (through unwarranted physi�  cal contact) by another is awarded  one to three free-throw attempts (depending on the circumstances of the  foul). A successful free throw is worth one point. Invented in 1891 by  James A. Naismith at the YMCA Training School in Springfield, Mass.,  basketball quickly became popular throughout the U.S., with games orga�  nized at the high school and collegiate level for both sexes. (For the first  game, Naismith used as goals two half-bushel peach baskets, which gave</p><p>the sport its name.) Women first played the game under a markedly dif�  ferent set of rules. The game developed internationally at a slower pace.  The first Olympic basketball contest was held in 1936, and the Federa�  tion Internationale de Basketball Amateur (FIB A) introduced world cham�  pionships for men and women in 1950 and 1953, respectively. In the U.S.,  high school and collegiate championship tournaments are traditionally  held in March and generate considerable excitement. A men�s professional  league was organized in 1898 but did not gain much of a following until  1949, when it was reconstituted as the National Basketball Association  (NBA). The first women�s professional leagues in the U.S. emerged dur�  ing the 1970s but failed after a year or two. The current Women�s National  Basketball Association (WNBA), owned by the NBA, was organized in  1997. Club and professional basketball outside the U.S. developed rap�  idly in the latter part of the 20th century.

The first bathyscaphe, the FNRS 2, was built in  1946^18 in Belgium. A later version, the Trieste, was acquired by the U.S.  Navy; in 1960 it dived to a record 35,810 ft (10,916 m) in the Mariana  Trench. The bathyscaphe consists of two main components: a steel cabin,  heavier than water and resistant to sea pressure, to accommodate the  observers; and a light container called a float, filled with gasoline, which,  being lighter than water, provides the necessary lifting power (replacing  cables, which had previously been used to support descending chambers  but had proven unreliable at great depths).</p><p>batik \b9-'tek\ Method of dyeing textiles, principally cottons, in which  patterned areas are covered with wax so that they will not receive colour.  Multicoloured effects are achieved by repeating the dyeing process sev�  eral times, the initial pattern of wax being boiled off and another design  applied before redyeing. Wax was applied with bamboo strips in Indone�  sia, where the technique originated. A small copper pot with a handle and  narrow applicator spout for applying the wax came into use in Java by  the mid 18th century; a wood-block wax applicator was developed in the  19th century. Dutch traders imported the cloth and the technique to  Europe. Today machines for applying wax in traditional Javanese patterns  reproduce the same effects as the hand-dyeing process.</p><p>Batiniyyah V.ba-ti-'ne-yoV School of Islamic thought that interpreted  religious texts exclusively on the basis of hidden rather than literal mean�  ings. Such interpretation gained currency around the 8th century among  esoteric Shiite sects, especially the schismatic Isma'njyyah, who believed  that beneath every obvious meaning lay a hidden, true meaning, which  the imam was empowered to interpret. While influenced by speculative  philosophy and theology, the Batiniyyah remained proponents of esoteric  knowledge. Sunnite Muslims condemned the Batiniyyah as enemies of  Islam for rejecting literal truth and producing confusion and controversy  through their multiple textual readings.</p><p>Batista \ba-'tes-ta\ (y Zaldivar), Fulgencio (b. Jan. 16, 1901,  Banes, Cuba�d. Aug. 6,1973, Guadalmina, near Marbella, Spain) Soldier,  president, and dictator who twice ruled Cuba (1933-44, 1952-59). Batista  worked his way up through the army and came to power as a strongman,  ruling first through associates, then as president himself from 1940. During  his first term he cultivated the support of the U.S., the army, organized  labour, and the civil service, and he achieved gains in the educational sys�  tem, public works, and the economy as a whole while enriching himself  and his associates. He lost the 1944 election but returned by way of an army  revolt in 1952. His second rule was a corrupt and brutal dictatorship that set  the stage for his overthrow by Fidel Castro on Jan. 1, 1959.</p><p>Batlle y Ordonez Vbat-ya-e-or-'thon-yasV Jose (b. May 21, 1856,  Montevideo, Uru.�d. Oct. 20, 1929, Montevideo) President of Uruguay  (1903-07, 1911-15). The son of a former president of Uruguay, he was  involved in politics from the 1880s. His narrow victory in the 1903 presi�  dential election led to a brief civil war, but when he held new elections  in 1905 he won again. He stepped down at the end of his term and was  reelected in 1911. He inaugurated labour reforms, limited the profits of  foreign-owned businesses, encouraged migration, nationalized and devel�  oped public works, ended the death penalty, and protected children born  out of wedlock. He is credited with transforming Uruguay into a stable,  democratic welfare state.</p><p>Baton Rouge Vbat^n-TiizhV City (pop., 2000: 227,818), capital of  Louisiana, U.S. Located on the Mississippi River, it is the state�s second-  largest city. Settled by the French in 1719, it was named for a red cypress  pole that marked a boundary between Indian tribes. The area was ceded  to Britain in 1763, then taken by the Spanish in the American Revolution.  Spain ceded Louisiana to France in 1800 but tried to retain Baton Rouge  at the time of the Louisiana Purchase (1803). In 1810 the city was annexed  to the U.S., and it became the state capital in 1849. The capital was trans�  ferred to other towns when Baton Rouge was occupied by Federal troops</p><p>during the American Civil War; in 1882 it regained its capital status. It has  deepwater port facilities and is an important petroleum refining centre.</p><p>battalion Tactical military organization composed of a headquarters  and two or more companies, batteries, or similar units and usually com�  manded by a field-grade officer such as a lieutenant colonel. The term has  been used in nearly every Western army for centuries and has had many  meanings. In the 16th-17th century, it denoted a unit of infantry used in  a line of battle and was loosely applied to any large body of men. During  the Napoleonic Wars, battalions were fighting units of the French army  under the administrative unit of the regiment. In the armies of the British  Commonwealth nations, infantry battalions are tactical units within regi�  ments. The typical U.S. Army battalion is a unit of 800-900 soldiers,  divided into a headquarters company and three rifle companies; two to  five battalions form the combat elements of a tactical brigade.

The first Battenbergs  were a family of German counts that died out c. 1314; the title was revived  in 1851. In 1917 the family members who lived in England renounced the  German title of prince of Battenberg and adopted Mountbatten as a sur�  name (�mount� being a translation of �Berg�). Prominent members of the  family included Philip, duke of Edinburgh, and Louis Mountbatten.</p><p>battered woman syndrome Psychological and behavioral pattern  displayed by female victims of domestic violence. Explanations that have  evolved since the late 1970s include learned helplessness, a �cycle of vio�  lence� theory, and a form of post-traumatic stress disorder. The term is a  legal concept rather than a psychiatric diagnosis and lacks clearly defined  criteria. It has been used to support legal arguments of self-defense, dimin�  ished responsibility, or insanity when a woman is accused of murdering or  assaulting her batterer, committing a crime under his coercion, or pro�  voking the behaviour the batterer is on trial for. Critics say the term cre�  ates a stereotyped image inadequate to describe individual experiences.</p><p>battering ram Medieval weapon consisting of a heavy timber with a  metal knob or point at the front. Rams were used to beat down the gates  or walls of a besieged city or castle. Usually suspended by ropes from the  roof of a movable shed, the timber was swung back and forth by its  operators so that it banged against the structure under siege. The shed�s  roof was covered with animal skins to protect the operators inside it from  bombardment with stones or fiery materials.</p><p>Battersea enamelware Painted enamelware made by Stephen The�  odore Janssen at York House in London�s Battersea district from 1753 to  1756. The ware is composed of soft white enamel over a copper ground.  The designs were applied by hand painting or by transfer printing: an  impression from an engraved metal plate brushed with enamel colours  was made on paper, and the design was then transferred to the object to  be decorated. Most of the objects (e.g., snuffboxes, watch cases) were  decorated with mottoes, portraits, landscapes, or flowers. The transfer  printing technique was first used for large-scale production at Battersea.</p><p>battery Any of a class of devices, consisting of a group of electro�  chemical cells (see electrochemistry), that convert chemical energy into  electrical energy; the term is also commonly applied to a single cell of  this kind. A wet cell (e.g., a car battery) contains free liquid electrolyte;  in a dry cell (e.g., a flashlight battery) the electrolyte is held in an absor�  bent material. Chemicals are arranged so that electrons released from the  battery�s negative electrode flow (see electric current) through a circuit  outside the battery (in the device powered by it) to the battery�s positive  electrode. The battery�s voltage depends on the chemicals used and the  number of cells (in series); the current depends on the resistance in the  total circuit (including the battery�and thus on electrode size). Multiple  batteries may be connected in series (the positive electrode of one to the  negative electrode of the next), which increases total voltage, or in par�  allel (positive to positive and negative to negative), which increases total  current. Batteries that are not rechargeable include standard dry cells used  in flashlights and certain wet cells for marine, mine, highway, and mili�  tary use. Car batteries, many kinds of dry cells used in cordless appli�  ances, and batteries for certain military and aerospace uses may be  recharged repeatedly.

It combined large size,  powerful guns, and heavy armour with fairly high speed and great cruis�  ing radius. The most powerful could hit targets at a range of more than  20 mi (30 km) and absorb heavy damage while remaining afloat and con�  tinuing to fight. It originated in early ironclad vessels with mixed sail and  steam propulsion, such as the French armoured frigate Gloire (1859). In  1906 HMS Dreadnought revolutionized battleship design by introducing  steam-turbine propulsion and an array of ten 12-in. (305-mm) guns. In  World War II (1939^15) battleships were used mainly for specialized tasks  such as bombarding enemy coastal defenses in amphibious warfare. After  the Persian Gulf War (1990�91), the U.S. decommissioned its last two  active battleships.</p><p>Batu \'ba-tu\ (d. c. 1255, Russia) Grandson of Genghis Khan and founder  of the Golden Horde.

During discharge, the sodium reacts with the  ceramic alumina electrolyte, losing electrons, which travel out the anode to the cir�  cuit the battery is powering. The ionic sodium then combines with sulfur, which has  acquired electrons from the cathode. The reaction is reversible, so the battery can  be recharged. The advantage of this battery over other rechargeables (e.g., lead-  acid, nickel-cadmium, or nickel-metal hydride batteries) is that it can provide the  same amount of power with a smaller, lighter battery. However, since the chemicals  must be heated to a molten state (about 325 �C, or 617 �F) and pure sodium is  very reactive, failure of the battery casing or ceramic electrolyte is potentially dan�  gerous.</p><p>� MERRIAM-WEBSTER INC.</p><p>the western part of the Mongol empire and given responsibility for the  invasion of Europe.

April 9, 1821, Paris,  France�d. Aug. 31, 1867, Paris)</p><p>French poet. While a law student he  became addicted to opium and hash�  ish and contracted syphilis. His early  reckless spending on fine clothes and  furnishings led to a life dogged by  debt. In 1844 he formed an associa�  tion with Jeanne Duval, a woman of  mixed black and white ancestry who  inspired some of his finest poetry. He  published a single novel, La fan-  farlo, in 1847. His discovery of the  works of Edgar Allan Poe in 1852 led  to years of work on Poe, which pro�  duced many masterly translations  and critical articles. His reputation  rests primarily on the extraordinary  poetry collection Les fleurs du mal  (1857; The Flowers of Evil), which  dealt with erotic, aesthetic, and  social themes in ways that appalled  many of his middle-class readers,  and he was accused of obscenity and  blasphemy. Though the title became a byword for depravity, the book  became perhaps the most influential collection of lyrics published in  Europe in the 19th century. His Petits poemes en prose (1868) was an  important and innovative experiment in prose poetry. He also wrote pro�  vocative essays in art criticism. Baudelaire�s later years were darkened by  disillusionment, despair, and mounting debt; his death at 46 resulted from  syphilis. He is regarded as the earliest and finest poet of modernism in  French.</p><p>Baudot \bo-'do\, (Jean Maurice) Emile (b. 1845, Magneux,  France�d. March 28, 1903, Sceaux) French engineer. In 1874 he pat�  ented a telegraph code that by the mid 20th century had supplanted Morse  code as the standard telegraphic alphabet. In Baudot�s code, each letter  is represented by a five-unit combination of current-on or current-off sig�  nals of equal duration, providing 32 permutations (sufficient for the  Roman alphabet, punctuation, and control of the machine�s mechanical  functions). Baudot also invented (1894) a distributor system for multiplex  (simultaneous) transmission of several messages on the same telegraphic  circuit or channel. The baud, a unit of data transmission speed, is named  for him.</p><p>Baudouin \bod-'waii\ I (b. Sept. 7, 1930, Stuyvenberg Castle, near  Brussels, Belg.�d.

After postwar exile in Switzerland, Baudouin became king on his father�s  abdication (1951). He helped restore confidence in the monarchy after the  stormy reign of his father and became a unifying force in a country divided  between Flemish- (Dutch- ) and French-speaking factions. Because Bau�  douin and his wife, Fabiola, were childless, he was succeeded by his  brother, Albert II.</p><p>Baudrillard \bo-dre-'yar\, Jean (b. 1929, Riems, France) French soci�  ologist, philosopher, and social critic. He taught sociology at the Univer�  sity of Paiis from 1966 to 1987. He is known for his theories of consumer  culture and of the influence of contemporary electronic media, especially  television. In a series of works in the 1970s, he applied ideas from semi�  otics to argue that consumer culture and especially advertising constitute  a �code� of images and ideals in terms of which individuals construct  their social identities. In works published during the 1980s and �90s, he  argued that the exchange of words, images, and other symbols through  increasingly pervasive electronic media created a new kind of reality, the  �hyper-real,� in which symbols become partly constitutive of the reality  they serve to represent.

It was founded by Walter Gropius with the ideal of integrating art,  craftsmanship, and technology. Realizing that mass production had to be  the precondition of successful design in the machine age, its members  rejected the Arts and Crafts Movement�s emphasis on individually  executed luxury objects. The Bauhaus is often associated with a severe  but elegant geometric style carried out with great economy of means,  though in fact the works produced by its members were richly diverse.  Its faculty included Josef Albers, Laszlo Moholy-Nagy, Lyonel Feininger,  Paul Klee, Vasily Kandinsky, and Marcel Breuer. The school was based in  Weimar until 1925, Dessau through 1932, and Berlin in its final months,  when its last director, Ludwig Mies van der Rohe, closed the school in  anticipation of the Nazis� doing so.

Conquered by the Romans in the 1st century bc (see  Noricum; Raetia), the area was taken by Charlemagne and incorporated into  his empire in 788. It became one of the great duchies of the Holy Roman  Empire. Under Maximilian I, Bavaria led the Catholic League in the Thirty  Years' War. It was overrun repeatedly in the context of larger wars in the  18th century. It joined the German Empire in 1871, while remaining a  kingdom. The king was overthrown in 1918; after a brief period of insta�  bility, Bavaria joined the Weimar Republic in 1919. Adolf Hitler had his first  power base in Bavaria in the 1920s. It adopted a new constitution in 1946  and became a state of the Federal Republic of Germany in 1949. It has  long been Germany�s most Roman Catholic area. Its largest cities are  Munich (its capital), Augsburg, and Nurnberg. Notable regions include the  Bavarian Alps, the Black Forest, and the Bohemian Forest. Bavaria is famous  for the beauty of its rolling landscape and the charm of its villages.</p><p>Bavarian Succession, War of the (1778-79) Conflict in which  Frederick II of Prussia prevented Joseph II of Austria from acquiring Bavaria.  After the death of the Bavarian elector Maximilian Joseph (1727-77), his  successor, Charles Theodore (1724-99), ceded Lower Bavaria to Austria.  Frederick II responded by declaring war (1778). There was little fighting  because each force was concerned with cutting its opponent�s communi�  cations and denying it supplies. Short on supplies, soldiers foraged for  potatoes; hence, the conflict was nicknamed the �potato war.� In 1779  Austria and Prussia signed a treaty giving Austria a fraction of the terri�  tory originally occupied.</p><p>Bax, Sir Arnold (Edward Trevor) (b.

His early works, influenced by the poetry  of William Butler Yeats, frequently evoke Celtic legend. His compositions  include seven symphonies, the orchestral works Spring Fire (1913),  November Woods (1917), and Tintagel (1919), piano sonatas, string quar�  tets, and numerous vocal works.</p><p>bay In architecture, any division of a building between vertical lines or  planes, especially the entire space included between the centerlines of two  adjacent vertical supports.

The invasion began with the bombing of Cuban  military bases; two days later a force of about 1,500 landed at several  sites along the coast, including the Bay of Pigs. The rebellion never mate�  rialized, the invasion force was quickly defeated, and more than 1,100  men were imprisoned. The result was a huge propaganda victory for Cas�  tro and a severe embarrassment for the administration of U.S. president  John F.

He served as secretary of state  (1885-89) and as ambassador to Britain (1893-97), the first U.S. repre�  sentative to Great Britain to hold that rank. A champion of arbitration, he  was critical of the aggressive position of Pres.

July 1, 1277, Damascus, Syria) Most eminent sultan of the MamlGk  dynasty. A Kipchak Turk, he was sold as a slave ( mamluk ) after a Mon�  gol invasion in the 1240s. He ended up in the service of the sultan of  Egypt�s AyyObid dynasty, who gave him military training. In 1250 his army  captured the Crusader king Louis IX, and he and other mamluk officers  murdered the last Ayyubid sultan, establishing the Mamluk dynasty. He  distinguished himself against an invading Mongol force at the Battle of  �Ayn Jalut (1260) and soon thereafter took the throne, when he murdered  the third Mamluk sultan. As sultan, he rebuilt the Syrian fortresses that  had been destroyed by the Mongols and built up the sultanate�s arma�  ments. He seized territory from the Crusaders that they were never to  recover. He harried the Mongols in Persia, attacking their allies (the Chris�  tian Armenians) and forging an alliance with the Mongols of the Golden  Horde against them. He sent military expeditions into Nubia and Libya.  He had diplomatic relations with James I of Aragon, Alfonso X of Leon  and Castile, and Charles of Anjou, as well as with the Byzantine emperor.  At home he built canals and the great mosque in Cairo that bears his name  and established efficient postal service between Cairo and Damascus.

After succeeding his father,  Murad II (d. 1389), Bayezid expanded Ottoman control of the shrinking  Byzantine Empire by conquering vast tracts of territory in the Balkans, thus  securing his rule south of the Danube. From 1391 to 1398 he blockaded  Constantinople (modern Istanbul), and he crushed the Hungarian Crusad�  ers at the Battle of Nicopolis in 1396. He then sought to widen Ottoman  control over Anatolia. Defeated by Timur at the Battle of Ankara in 1402,  Bayezid died in captivity. He was succeeded by his son, Mehmed I, after  an interregnum of some 10 years.</p><p>Bayezid \,bI-3-'zed\ II (b. December 1447/January 1448?, Demotika,  Thrace, Ottoman Empire�d. May 26, 1512, Demotika) Sultan who con�  solidated control of the Ottoman Empire begun by his father, Mehmed II.  After taking the throne in 1481, he reversed his father�s policies of expro�  priating Muslim religious properties and rejected his pro-European ori�  entation but continued the policy of territorial conquest. Under him,  Herzegovina came under direct Ottoman control, and the Ottoman hold  over the Crimea and Anatolia was strengthened. He fought the Safavid  dynasty in the east, the MamlOk dynasty in the south, and the Venetians in  the west. At home he built mosques, colleges, hospitals, and bridges and  supported jurists, scholars, and poets. He abdicated in favour of his son,  Selim I, a month before his death.</p><p>Baykal, Lake See Lake Baikal</p><p>Bayle \'bel\, Pierre (b. Nov. 18, 1647, Carla-le-Comte, France�d.  Dec. 28, 1706, Rotterdam, Neth.) French philosopher. Educated at a Jesuit  school, he converted to Roman Catholicism but later reverted to his origi�  nal Calvinist faith. His religious views led to his losing professorships  first at Sedan and later at Rotterdam. He was convinced that philosophi�  cal reasoning led to universal skepticism, but that nature compelled man�  kind to adopt beliefs on the basis of blind faith. The bulk of his Historical  and Critical Dictionary (1697) consists of quotations, anecdotes, com�  mentaries, and erudite annotations that cleverly undo whatever orthodox  Christian beliefs the articles express; and it was condemned by religious  authorities. Bayle�s oblique method of subversive criticism was later  adopted by the contributors to the Encyclopedie of Denis Diderot.</p><p>Baylis, Lilian (Mary) (b. May 9, 1874, London, Eng.�d. Nov. 25,  1937, London) British theatrical manager and founder of the Old Vic. She  assisted her aunt, Emma Cons, in the operation of the Royal Victoria Hall  and Coffee Tavern, and on Cons�s death in 1912 she converted the hall into  the Old Vic, which became famous for its Shakespearean productions.  Between 1914 and 1923 the theatre staged all of William Shakespeare�s  plays, a feat no other playhouse had attempted. In 1931 she took over the  derelict Sadler�s Wells Theatre and made it a centre of opera and ballet.</p><p>Bayliss, Sir William Maddock (b. May 2, 1860, Wolverhampton,  Staffordshire, Eng.�d. Aug. 27, 1924, London) British physiologist. He  and Ernest H. Starling studied nerve-controlled blood-vessel contraction  and dilation and discovered the peristaltic wave. In 1902 they showed that  dilute hydrochloric acid mixed with partly digested food activates a  chemical in the duodenum that they called secretin, because it stimulates  secretion of pancreatic juice. This marked the discovery of hormones, a  term the men coined. Bayliss also showed how the enzyme trypsin was  formed from inactive trypsinogen and measured precisely the time it took  to digest protein. His recommendation of gum-saline injections for wound  shock saved many lives in World War I.</p><p>Baylor, Elgin (b. Sept. 16, 1934, Washington, D.C., U.S.) U.S. basket�  ball player. At 6 ft 5 in. (1.96 m) Baylor played for the Minneapolis (later  Los Angeles) Lakers of the NBA from 1958 to 1971. A high-scoring and  acrobatic forward, Baylor averaged 27.4 points for his career, placing him  in the top five of all time.</p><p>bayonet Short, sharp-edged, sometimes pointed weapon, designed for  attachment to the muzzle of a firearm. According to tradition, it was  developed in Bayonne, France, early in the 17th century and soon spread  throughout Europe. The earliest design, the plug bayonet, was inserted  into the muzzle of a musket, thus preventing the musket from being fired  until the bayonet was removed. Later designs, including the socket bayo�  net invented by Sebastien Le Prestre de Vauban (1688), slipped it over the  muzzle. Repeating firearms greatly reduced its combat value. By World  War I it had become an all-purpose knife.</p><p>bayou \'bl-ii\ Still or slow-moving section of marshy water, usually a  creek, secondary watercourse, or minor river that is a tributary of another  river or channel. It may occur in the form of an oxbow lake. Bayous are  typical of Louisiana�s Mississippi River delta.</p><p>Bayreuth \bI-'roit\ City (pop., 2001 est.: 74,500), east-central Germany.  It is situated northeast of Nurnberg. Founded in 1194 under Bishop Otto  II of Bamberg, it came under the burgrave of Niirnberg in 1248-1398 and  the margraves of Brandenburg-Kulmbach in 1603-1769. The margraves  patronized the arts and commissioned many Baroque buildings that still  exist. It was ceded to Prussia in 1791, captured by Napoleon in 1806, and  passed to Bavaria in 1810. Composer Richard Wagner settled there in 1872  and designed the Festspielhaus, where Wagner festivals have been held  since its opening in 1876. Manufactures include machinery, textiles,  chemicals, pianos, porcelain, and glassware.</p><p>Bazin \ba-'za n \, Henri-Emile (b. Jan. 10, 1829, Nancy, France�d.  Feb. 7, 1917, Dijon) French engineer. As an assistant to H.-P.-G. Darcy  (1803-1858), he completed his program of tests on resistance to water  flow in channels after Darcy�s death, producing the classic study of the  subject. He later studied the problem of wave propagation (see wave) and  the contraction of fluid flowing through an orifice. In 1854 he enlarged  the Canal de Bourgogne and made it profitable for commercial naviga�  tion. In 1867 he suggested the use of pumps for dredging rivers, leading  to the construction of the first suction dredgers.</p><p>bazooka Shoulder-type rocket launcher adopted by the U.S. Army in  World War II.

Officially named the M9A1  Rocket Launcher, it was called bazooka after the crude horn of that name  used by a popular radio comedian. It was developed chiefly for attacking  tanks and fortified positions at short range. The U.S. Army abandoned it  during the Vietnam War in favour of lighter-weight antitank weapons.</p><p>BBC in full British Broadcasting Corp. Publicly financed broad�  casting system in Britain. A private company at its founding in 1922, it  was replaced by a public corporation under royal charter in 1927. The  BBC World Service began in 1932, and by the 1990s was broadcasting  programs in 38 languages to 120 million people worldwide. BBC televi�  sion service, which kept its monopoly on television service until a com�  mercial channel began broadcasting in 1954, introduced regular color  broadcasts in Europe in 1967. The BBC radio monopoly ended in 1972.  The BBC today offers five radio networks and two national television  channels.</p><p>BBS See bulletin-board system</p><p>BCS theory Comprehensive theory that explains the behaviour of super�  conducting materials. It was developed in 1957 by John Bardeen, Leon  Cooper, and J. Robert Schrieffer (b. 1931), whose surname initials pro�  vide its name. Cooper discovered that electrons in a superconductor are  grouped in pairs (Cooper pairs) and that the motions of all the pairs within  a single superconductor constitute a system that functions as a single  entity. An electric voltage applied to the superconductor causes all Coo�  per pairs to move, forming an electric current. When the voltage is  removed, the current continues to flow because the pairs encounter no  opposition. See also superconductivity.</p><p>beach Sediments that accumulate along sea or lake shores. One type of  beach occurs as a sediment strip bordering a rocky or cliffy coast. A sec�  ond type is the outer margin of a marine plain. The third type consists of  naiTOw sediment barriers stretching for dozens or even hundreds of miles  parallel to the general direction of the coast. These barriers separate  lagoons from the open sea and generally are dissected by tidal inlets.  Certain sediment forelands, such as spits, points, and tombolos (which  connect an island with a mainland), occasionally are called beaches.</p><p>Beach, Amy Marcy orig. Amy Marcy Cheney known as Mrs.  H.H.A. Beach (b. Sept. 5, 1867, Henniker, N.H., U.S.�d. Dec. 27,  1944, New York, N.Y.) U.S. composer and pianist. A precociously bril�  liant musician, she performed as soloist with major orchestras in the U.S.  and Europe. As a composer she was devoted to German Romanticism  rather than American themes or sources. Her best-loved works were her  songs. Her Gaelic Symphony (1894) was the first symphony by an Ameri�  can woman. Other works include a piano concerto (1899), the choral  pieces The Chambered Nautilus (1907) and Canticle of the Sun (1928),  the opera Cabildo (1932), and a piano quintet (1907).</p><p>Beach Boys U.S. rock group. The band was formed in California in  1961 by brothers Brian Wilson (b. 1942) on keyboards and bass, Dennis  Wilson (1944-83) on drums, and Carl Wilson (1946-98) on guitar; their  cousin Mike Love (b. 1941) on drums; and Alan Jardine (b. 1942) on gui�  tar. Within a year they launched a string of surfing-oriented hits marked  by close vocal harmony, including �Surfin� Safari� and �California Girls.�  By 1966 they had released more than 10 albums, including Pet Sounds  (1966), considered their best. Despite Brian Wilson�s reclusiveness due  to stress- and drug-related breakdowns, the band continued to make  recordings into the 1980s and toured into the 1990s.</p><p>beach flea See sand flea</p><p>bead Small object, usually pierced for stringing. It may be made of vir�  tually any material�wood, shell, bone, seed, nut, metal, stone, glass, or  plastic�and is worn or affixed to another object for decorative or, in some  cultures, magical purposes. The earliest Egyptian beads (c. 4000 bc) were  made of stone, feldspar, lapis lazuli, carnelian, turquoise, hematite, or  amethyst and were variously shaped (sphere, cone, shell, animal head).  By 3000-2000 bc, gold beads in tubular shapes were in use. From the  Middle Ages to the 18th century, trade in beads was enormous. Today the  richness of beadwork varies with fashion.</p><p>Beadle, George Wells (b. Oct. 22, 1903, Wahoo, Neb., U.S.�d.  June 9, 1989, Pomona, Calif.) U.S. geneticist. He earned his Ph.D. from  Cornell University. While studying Drosophila, he realized that genes  must influence heredity chemically and designed a complex technique to</p><p>determine the nature of those effects, showing that something as appar�  ently simple as eye colour results from a long series of chemical reac�  tions, which are affected by genes. With Edward L. Tatum, he found that  the total environment of a bread mold could be varied so that researchers  could locate and identify mutations relatively easily, concluding that each  gene determines the structure of a specific enzyme, which in turn allows  a single chemical reaction to proceed. For the �one gene, one enzyme�  concept, they shared a 1958 Nobel Prize with Joshua Lederberg. Beadle  later served as president of the University of Chicago (1960-68).</p><p>beadwork Ornamental work in beads. In the Middle Ages beads were  used to embellish embroidery work. In Renaissance and Elizabethan  England, clothing, purses, fancy boxes, and small pictures were adorned  with beads. In the 19th-20th century beadwork proliferated in dress deco�  ration. Beads are used as ornamentation on a variety of objects (clothing,  masks, weapons, dolls) in many cultures, including the Native American,  African, and Oceanic.</p><p>beagle Breed of small hound, popular as both a pet and a hunter. It looks  like a small foxhound, with large  brown eyes, hanging ears, and a  short coat that is usually a combina�  tion of black, tan, and white. Beagles  are solidly built and heavy for their  height. Two sizes are recognized:  those standing less than 13 in. (33  cm) and weighing about 18 lbs (8  kg), and those standing about 15 in.</p><p>(38 cm) and weighing about 30 lbs  (13.5 kg). Beagles generally excel as  rabbit hunters and are typically alert  and affectionate.</p><p>Beagle Channel Channel,  extreme southern South America. Separating the main islands of Tierra del  Fuego from smaller islands in the archipelago, it is about 150 mi (240 km)  long and 3-8 mi (5-13 km) wide. The eastern portion forms part of the  Chile-Argentina border, while the western portion lies entirely within  Chile. It was named for the British ship HMS Beagle, in which Charles  Darwin explored the area.</p><p>beak or bin Stiff, projecting oral structure of birds and turtles (both of  which lack teeth) and certain other animals (e.g., cephalopods and some  insects, fishes, and mammals). The term bill is preferred for the beak of  a bird, which is composed of upper and lower jaws covered by a horny  sheath of skin, with the nostrils on top, usually at the base. The shapes  and sizes of bills are adapted for obtaining food, preening, building nests,  and other functions; they range from the long, slim bills of nectar-sipping  hummingbirds to the sturdy, curved, nut-cracking bills of parrots.</p><p>Beaker culture Late Neolithic and early Bronze Age culture of north�  ern and western Europe. The people are known for a group of distinctive  bell-shaped earthenware beakers decorated with toothed stamps, probably  used in rituals of consumption. The Beaker people buried their dead in  simple graves but also in megalithic tombs in western Europe. They used  the bow and arrow as well as copper daggers and spearheads. As they  searched for gold and copper, they spread metallurgy into other parts of  Europe. They eventually mixed with the Battle-Ax culture and spread  from central Europe to eastern England.</p><p>beam In building construction, a horizontal member spanning an open�  ing and carrying a load. The load may be a wall above the opening (see  post-and-beam system) or it may be a floor or roof. Beams may be of wood,  steel or other metals, reinforced or prestressed concrete, plastic, or even  brick with steel reinforcement. For weight reduction, metal beams are  I-shaped, having a thin vertical web and thicker horizontal flanges where  greater stress occurs. A joist is any of a series of small parallel beams  supporting a floor or roof. See also girder, spandrel.</p><p>bean Seed or pod of certain leguminous plants (see legume). The mature  seeds of the principal food beans, except soybeans, are similar in compo�  sition, though they differ widely in eating quality. Rich in protein and  providing moderate amounts of iron and vitamins B 1 and B 2 , fresh or dried  beans are used worldwide for cooking. Varieties differ greatly in size,  shape, colour, and tenderness of the immature pods. The common string,  snap, or green bean ( Phaseolus vulgaris ) of Central and South American  origin is the dominant edible-podded bean in the U.S., second to the soy-</p><p>Beagle</p><p>SALLY ANNE THOMPSON/EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Bean &#x25BA; Beat movement I 183</p><p>bean in importance. Third in importance is the broad, or fava, bean ( Vicia  faba ), the principal bean of Europe. The lima bean ( P. limensis ), of Cen�  tral American origin, is commercially important in few countries outside  the Americas. The scarlet runner bean (P. coccineus) is native to the New  World tropics and is grown in Europe for its attractive flowers and fleshy  immature pods. The mung bean, or green gram (P. aureus ), is native to  India and grown extensively in the Orient for food.</p><p>Bean, Roy (b. 1825?, Mason county, Ky., U.S.�d. March 16, 1903,  Langtry, Texas) U.S. justice of the peace and saloonkeeper. He left Ken�  tucky in 1847 and moved from town to town, killing at least two men in  duels, before settling in Texas. During the American Civil War he first  served with Confederate regulars and then was a blockade runner in Texas,  becoming so prosperous that he was able to live at ease in San Antonio  for some 16 years. In 1882 he moved to a site on the lower Pecos River  that he named for Lillie Langtry, opened a saloon, and dispensed hard,  commonsensical, and prankish rulings as an unofficial magistrate, styling  himself the �law west of the Pecos.�</p><p>bear Generally massive, short-legged mammals constituting the family  Ursidae. Bears are the most recently evolved carnivore, found in Europe,  Asia, and the Americas. Closely related to the dog and the raccoon, most  bears climb with ease and are strong swimmers. As a family, they are  omnivores, but dietary preferences vary among species (the polar bear  feeds mainly on seals, the spectacled bear on vegetation, etc.). Though they  do not truly hibernate, bears often sleep fitfully through much of the win�  ter. They live 15-30 years in the wild but much longer in captivity. They  have been hunted as trophies, for hides, and for food.

In June a small group captured  Sonoma, a settlement north of San Francisco, and declared independence,  raising a flag that featured a grizzly bear. Capt. John C. Fremont soon  arrived to give his support and was elected to head the �republic.� In July  U.S. forces occupied San Francisco and Sonoma and claimed California  for the U.S. The bear flag later became the state flag.</p><p>bear grass Either of two species of North American plants that make  up the genus Xerophyllum, in the lily family. The western species, X. tenax,  also known as elk grass, squaw grass, and fire lily, is a smooth, light-  green mountain perennial with a stout, unbranched stem and grasslike,  rough-edged leaves at the bottom. It flowers at five to seven years, bear�  ing a large cluster of small, creamy white flowers at the top of the stem.  The turkey beard (X. asphodeloides ) of southern North America is a simi�  lar plant that grows in dry pine barrens. In the southern and southwest�  ern U.S., the name bear grass is given to various kinds of yucca and to  the camas ( Camassia scilloides ) and the aloelike Dasylirion texanum.</p><p>bear market In securities and commodities trading, a declining mar�  ket. A bear is an investor who expects prices to decline and, on this  assumption, sells a borrowed security or commodity in the hope of buy�  ing it back later at a lower price, a speculative transaction called short-  selling. See also bull market.</p><p>bearberry Flowering, prostrate, evergreen shrub {Arctostaphylos uva-  ursi) of the heath family, growing widely throughout North America in  rocky and sandy woods and open areas. It has woody stems that are often  5-6 ft (1.5-1.8 m) long. Roots develop from stem joints, and the plant  spreads, forming a broad, massive ground cover. The foliage turns bronzy  in winter. The white, pink, or pink-tipped flowers are shaped like a  narrow-mouthed bell. The berries are red.</p><p>Beard, Charles A(ustin) (b. Nov. 27, 1874, near Knightstown, Ind.,  U.S.�d. Sept. 1, 1948, New Haven, Conn.) U.S. historian. Beard taught  at Columbia University (1904-17) and cofounded New York�s New  School for Social Research (1919). He is best known for iconoclastic  studies of the development of U.S. political institutions, emphasizing the  dynamics of socioeconomic conflict and change and analyzing motiva�  tional factors in the founding of institutions. His works include An Eco�  nomic Interpretation of the Constitution of the United States (1913),  claiming that the Constitution was formulated to serve the economic inter�  ests of the founders; The Economic Origins of Jeffersonian Democracy  (1915); and, with his wife, Mary R.

In 1945 he  became the first chef to demonstrate cooking on network television.  Through his Greenwich Village cooking school he influenced such future  chefs as Julia Child and Craig Claiborne (b. 1920�d. 2000). He champi�  oned simple American and English dishes and wrote one of the first seri�  ous books on outdoor cooking. His more than 20 cookbooks include  James Beard�s American Cookery (1972) and Beard on Bread (1973).</p><p>Bearden, Roma re (Howard) (b. Sept. 2, 1914, Charlotte, N.C.,  U.S.�d. March 11, 1988, New York, N.Y.) U.S. painter. He studied with  George Grosz at the Art Students League and Columbia University. After  military service in World War II, he attended the Sorbonne and traveled  in Europe. During this time he achieved recognition for his complex,  semiabstract collages of photographs and painted paper on canvas. The  narrative structure of his work is clear; aspects of African American cul�  ture, including ritual, music, and family, were his predominant themes.  By the 1960s Bearden was recognized as the preeminent collagist in the  U.S. He is regarded as one of the most important African American art�  ists of the 20th century.</p><p>Beardsley, Aubrey (Vincent) (b. Aug. 21, 1872, Brighton, Sussex,  Eng.�d. March 16, 1898, Menton, Fr.) British illustrator. His only for�  mal training was a few months of evening classes at the Westminster  School of Art. His style was based on the work of Edward Burne-Jones  and Japanese woodcuts, and he quickly became a master of the curvilin�  ear black-and-white ornamental illustration popularized by the Art Nou�  veau movement. In 1893 he illustrated an edition of Sir Thomas Malory�s  Le Morte Darthur, and in 1894 he achieved notoriety with his erotic illus�  trations for the English version of Oscar Wilde�s Salome. He became art  editor and illustrator of the new quarterly The Yellow Book that same year.  He died at age 25 of tuberculosis.</p><p>bearing In machine construction, a connector (usually a support) that  permits the connected members to rotate or to move in a straight line rela�  tive to one another. Often one of the members is fixed, and the bearing  acts as a support for the moving member. Most bearings support rotating  shafts against either transverse (radial) or thrust (axial) loads. To mini�  mize friction, the contacting surfaces in a bearing may be separated by a  film of oil or gas; these are sliding bearings (see oil seal). In ball bearings  and roller bearings, the surfaces are separated by balls or rollers.</p><p>bearing wall or load-bearing wall Wall that carries the load of  floors and roof above in addition to its own weight. The traditional  masonry bearing wall is thickened in proportion to the forces it has to  resist: its own weight, the dead load of floors and roof, the live load of  people, as well as the lateral forces of arches, vaults, and wind. Such walls  may be much thicker toward the base, where maximum loads accumu�  late. Bearing walls may also be framed and sheathed or constructed of  reinforced concrete.</p><p>Bearn \ba-'am\ Historical region and former province, southwestern  France. It was bounded by Gascony and the Pyrenees; its capital was Pau.  It formed part of Aquitania under the Romans; it was later devastated by  the Vandals and Visigoths.

It was the  approximate limit of Alexander the Great�s invasion of India in 326 bc.</p><p>beat In physics, the pulsation resulting from a combination of two waves  of slightly different frequency. Beat frequency is the difference between  the frequencies of the combining waves. When the interfering frequen�  cies are in the audible range, the beats are heard as alternating soft and  loud pulses. The human ear can detect beats with frequencies up to 10  hertz, or 10 beats per second. Piano tuners listen for beats when compar�  ing the pitch of a tuning fork to that of a vibrating string; when no beats  are heard, the fork and string are at the same frequency. Ultrasonic or  inaudible frequencies can be superimposed to produce audible beats,  allowing the detection of vocal sounds produced by bats or dolphins.</p><p>Beat movement American social and literary movement of the 1950s  and �60s.

Its adherents expressed alienation from conven�  tional society and advocated personal release and illumination through  heightened sensory awareness and altered states of consciousness. Beat  poets, including Lawrence Ferlinghetti, Allen Ginsberg, Gregory Corso  (1930-2001), and Gary Snyder, sought to liberate poetry from academic  refinement, creating verse that was vernacular, sometimes sprinkled with  obscenities, but often powerful and moving. Jack Kerouac and William S.  Burroughs developed an unstructured, spontaneous, sometimes hallucina�  tory approach to prose writing that was designed to convey the imme�  diacy of experience. The Beat movement had faded by c. 1970, though  its influence continued to be felt decades later.</p><p>Beatles British rock group that came to personify the counterculture of  the 1960s. Its principal members, all born in Liverpool, Eng., were Paul  McCartney, John Lennon, George Harrison, and Ringo Starr. The group  began with the pairing of McCartney and Lennon in 1956; Harrison joined  in 1957, and Stu Sutcliffe and Pete Best later. In 1960 they adopted the  name the Beatles. In 1962 they signed a recording contract and replaced  Best with Starr (Sutcliffe had left the group in 1961). The release in  1962-63 of such songs as �Please Please Me� and �I Want to Hold Your  Hand� made them England�s most popular rock group, and in 1964 �Bea-  tlemania� struck the U.S. Originally inspired by Chuck Berry, Elvis Pres�  ley, Little Richard, and Buddy Holly, among others, their direct, energetic  songs kept them at the top of the pop charts. Their long hair and tastes in  dress were influential throughout the world, as were their experimenta�  tion with hallucinogenic drugs and Indian mysticism and their involve�  ment with the politics of peace. From 1965 to 1967 the Beatles� music  rapidly evolved, becoming increasingly subtle, sophisticated, and  varied�ranging from ballads such as �Yesterday� to the psychedelic hard  rock of �Tomorrow Never Knows.� Their public performances ended in  1966. Albums such as Rubber Soul (1965), Revolver (1966), and The  Beatles (�White Album,� 1968) set new trends in rock. In 1967 they pro�  duced Sgt. Pepper�s Lonely Hearts Club Band , an album novel for its  conception as a dramatic whole, use of electronic music, and character as  a studio work not reproducible onstage. They appeared in the films A Hard  Day�s Night (1964) and Help! (1965). The group dissolved in 1970. In  1988 the Beatles were inducted into the Rock and Roll Hall of Fame, and  Lennon (1994), McCartney (1999), and Harrison (2004) were also  inducted as solo performers.</p><p>Beaton, Sir Cecil (Walter Hardy) (b.

June 23, 1794, Paris, France) French politician and  general, first husband of Josephine. A liberal noble, he became a promi�  nent figure during the French Revolution. He presided over the Constitu�  ent Assembly in 1791, served with gallantry in the army, and was named  general in chief of the Army of the Rhine in 1793. He was guillotined  during the Reign of Terror, largely because he was a noble. He was the  father of Eugene and Hortense de Beauharnais and the grandfather of Napo�  leon III.</p><p>Beauharnais, Eugene de (b. Sept. 3, 1781, Paris, France�d.

In 1804 he received the title of prince  and was appointed archchancellor of state. He was named Napoleon�s  viceroy in Italy (1805), where he reorganized public finances, built roads,  and introduced the French legal system. As commander of the Italian  army, he fought admirably in various conflicts. In 1814 he held out in  Italy against the Austrians and the Neapolitans but was forced to con�  clude an armistice. He retired to the Bavarian court of his wife�s family.</p><p>Beauharnais, (Eugenie-) Hortense de (b. April 10, 1783, Paris,  France�d. Oct. 5, 1837, Arenenberg, Switz.)

When he became king of Holland, she was named queen.  The marriage was unhappy but produced three children, including the  future Napoleon III. When Napoleon was exiled in 1814, Hortense became  the centre of Bonapartist intrigue, and her support of Napoleon during his  return led to her banishment from France in 1815, after which she settled  in Switzerland.</p><p>Beaujolais X.bo-zho-'laX Region in northern Rhone and northeastern  Loire departments, east-central France.

May 18, 1799, Paris) French playwright.  Son of a watchmaker, he invented a clockwork mechanism and became  embroiled in lawsuits over its patent; a series of witty pamphlets he wrote  in his defense established his reputation as a writer. His comedy The Bar�  ber of Seville (1772) was kept off the stage for three years because it criti�  cized the aristocracy. His Marriage of Figaro (1784) similarly censured  the nobility and it, too, was initially banned. The plays became famous  operas by Gioacchino Rossini and Wolfgang Amadeus Mozart, respec�  tively. He founded the Societe des Auteurs (1777) to enable playwrights  to obtain royalty payments. His wealth led, ironically, to his temporary  imprisonment during the French Revolution, an event his plays were  sometimes said to have sparked.</p><p>Beatrix of The Netherlands.</p><p>COURTESY OF THE ROYAL NETHERLANDS EMBASSY;  PHOTOGRAPH, MAX KOOT</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Beaumont &#x25BA; Beccafumi I 185</p><p>Beaumont Vbo-.mantA City (pop., 2000: 113,866), southeastern Texas,  U.S. Lying at the head of navigation on the Neches River, it is connected  to the Gulf of Mexico by the Sabine-Neches Canal and is a major port of  entry.

March 6, 1616, London) British playwright. He is known  chiefly for the 10 very popular plays on which he collaborated with John  Fletcher (1579-1625) c. 1606�13. These included the tragicomedies The  Maides Tragedy, Phylaster, and A King and No King. Forty other plays  attributed to them were later found to have been written by others. Their  independent work includes Beaumont�s poetry and his parody The Knight  of the Burning Pestle (1607) and Fletcher�s pastoral The Faithful Shep�  herdess (1608). After Beaumont retired in 1613, Fletcher collaborated  with other playwrights, possibly including William Shakespeare, with whom  he may have written King Henry the Eighth and The Two Noble Kinsmen.</p><p>Beaumont, William (b.

When treating a trapper whose abdomen had been perfo�  rated by a shotgun blast, Beaumont collected gastric juice for analysis and  showed that it contained hydrochloric acid, which supported his belief that  digestion was a chemical process. He also reported on the effects of dif�  ferent foods on the stomach and established alcohol as a cause of gastritis.</p><p>Beauregard Vbo-r9-,gard\, P(ierre) G(ustave) T(outant) (b.

After Louisiana seceded in 1861, he resigned his  commission and became a general in the Confederate army. He com�  manded the forces that bombarded Fort Sumter, S.C., was on the field at  the First Battle of Bull Run (1861), and assumed command at the Battle  of Shiloh after the death of Gen. Albert Sidney Johnston (1862). He con�  ducted the defenses of Charleston, S.C., and Richmond, Va. Though a  capable commander, his penchant for questioning orders sometimes bor�  dered on insubordination. After the war he quarreled with other generals�  accounts of his role.</p><p>Beauvoir Vbo-.vwarV, Simone (Lucie-Ernestine-Marie-  Bertrand) de (b. Jan. 9, 1908, Paris, France�d. April 14, 1986, Paris)  French writer and feminist. As a student at the Sorbonne, she met Jean-  Paul Sartre, with whom she formed a lifelong intellectual and romantic  bond. She is known primarily for her treatise The Second Sex (1949), a  scholarly and passionate plea for the abolition of what she called the myth  of the �eternal feminine�; the book became a classic of feminist literature.  She also wrote four admired volumes of autobiography (1958-72), philo�  sophical works that explore themes of existentialism, and fiction, notably  The Mandarins (1954, Prix Goncourt). The Coming of Age (1970) is a  bitter reflection on society�s indifference to the elderly.</p><p>Beaux-Arts \bo-'zar\ style or Second Empire style or Second  Empire Baroque Architectural style developed at the Ecole des Beaux-  Arts in Paris. It enjoyed international dominance in the late 19th century  (see Second Empire) and rapidly became an official style for many of the  new public buildings demanded by expanding cities and their national  governments. Beaux-Arts buildings are typically massive and have a sym�  metrical plan with rooms arranged axially, profuse Classicist detail, and  pavilions that extend forward at the ends and centre. Among the most  admired Beaux-Arts structures is the Paris Opera.</p><p>beaver Either species of the  aquatic rodent family Castoridae  (genus Castor ), both of which are  well known for building dams. Bea�  vers are heavyset and have short legs  and large, webbed hind feet. They  grow as large as 4 ft (1.3 m) long,  including the 1-ft (30-cm) tail, and as  heavy as 66 lb (30 kg). Beavers build  their dams of sticks, stones, and mud  in small rivers, streams, and lakes,  often producing sizable ponds. With  their powerful jaws and large teeth,  they can fell medium-size trees,</p><p>whose branches they use in their dams and whose tender bark and buds  they eat. One or more family groups share a dome-shaped stick-and-mud  lodge built in the water, with tunnel entrances below water level. Ameri�  can beavers (C. canadensis) range from northern Mexico to the Arctic.  Their prized pelts stimulated the exploration of western North America,  and by 1900 beavers were trapped to near extinction.

After making a fortune in Montreal as a financier,  he moved to England and became active in politics as a Conservative.  Beginning in 1916, he took over or founded newspapers, including the  London Daily Express, Sunday Express, and Evening Standard. Idiosyn�  cratic and very successful, he became a �press lord� and a champion of  individual enterprise and British imperial interests. He held various high  government appointments, including positions in the British Cabinet dur�  ing both World Wars, but he never fully achieved the political power he  sought.</p><p>Bebel \'ba-bol\, August (b.

Influenced by the ideas of  Wilhelm Liebknecht, in 1869 he helped found the Social Democratic Labour  Party (later the Social Democratic Party) and became its most influential  and popular leader for more than 40 years. He served in the Reichstag in  1867, 1871�81, and 1883-1913. He spent a total of nearly five years in  prison on such charges as �libel of Bismarck.� He wrote a number of  works, including Woman and Socialism (1883), a powerful piece of Social  Democratic propaganda.</p><p>Bebey, Francis (b.

He worked for radio stations and then for UNESCO, researching and  documenting traditional African music. Meanwhile, he also composed and  recorded his own highly experimental music that often incorporated Latin  American, Western, and African elements. Because of this, he is some�  times considered �the father of world music.� He also wrote two books  about African music and several works of fiction.</p><p>bebop or bop Jazz characterized by harmonic complexity, convoluted  melodic lines, and frequent shifting of rhythmic accent. In the mid-1940s,  a group of musicians, including Dizzy Gillespie, Thelonious Monk, and Char�  lie Parker, rejected the conventions of swing to pioneer a self-consciously  artistic extension of improvised jazz,  which set new technical standards of  velocity and harmonic subtlety. Two  genres grew out of bebop in the  1950s: the delicate, dry, understated  approach that came to be known as  cool jazz, and the aggressive, blues-  tinged earthiness of hard bop.</p><p>Beccafumi N.bek-o-'fii-meV  Domenico orig.

He became an inter�  national celebrity in 1764 with the publication of Crime and Punishment,  the first systematic statement of principles governing criminal punish�  ment, in which he argued that the effectiveness of criminal justice  depended more on the certainty of punishment than on its severity. The  book greatly influenced criminal-law reform in western Europe. In later  years, Beccaria lectured at Milan�s Palatine School and served as a pub�  lic official, dealing with such issues as monetary reform, labour relations,  and public education.</p><p>Bechet \b3-'sha\, Sidney (b.

His emergence as a soloist from the New Orleans tradition of col�  lective improvisation (see Dixieland) established his reputation in the mid-  1920s. He produced a large, warm tone with a wide and rapid vibrato. His  mastery of drama and his use of critically timed deviations in pitch (�note  bending�) had a long-lasting influence, because they were absorbed by  his disciple Johnny Hodges. From the late 1940s he was based in Paris.</p><p>Bechtel Vbek-LL, Stephen D(avison) (b. Sept. 24, 1900, Aurora,  Ind., U.S.�d. March 14, 1989, San Francisco, Calif.)

Bechtel Co. in 1925. In 1937 he and John McCone  formed Bechtel-McCone Corp., a builder of refineries and chemical  plants. The companies built ships and made aircraft parts during World  War II. After the war, the newly formed Bechtel Corp. became one of the  world�s largest construction and engineering firms, building pipelines in  Canada, the Middle East, and elsewhere and constructing power plants all  over the world. The Bechtel companies helped construct the Hoover Dam,  the Alaska oil pipeline, and the city of Al-Jubayl in Saudi Arabia.

As a professor at Columbia University and the University of Chi�  cago, he applied the methods of economics to aspects of human behaviour  previously considered the domain of sociology and demography. In  Human Capital (1964) and A Treatise on the Family (1981), he advanced  the theory that rational economic choices, based on self-interest, govern  most human activities, even apparently noneconomic activities such as  the formation of families.

A brilliant  administrator, diplomat, and military  strategist, he aided the king in  increasing the royal power. Resistant  to the Gregorian reform movement  that asserted the autonomy of the  church, Henry hoped to reinforce  royal control of the church by  appointing Becket archbishop of  Canterbury in 1162. Becket, how�  ever, embraced his new duties  devoutly and opposed royal power in  the church, especially proclaiming  the right of offending clerics to be  tried in ecclesiastical courts. The  king issued the Constitutions of  Clarendon (1164) listing royal rights  over the church, and he summoned  the archbishop to trial. Becket fled to France and remained in exile until  1170, when he returned to Canterbury and was murdered in the cathedral  by four of Henry�s knights, traditionally said to be acting in response to  the king�s angry words. Becket�s tomb, which was visited by Henry in  an act of penance, became a site of pilgrimage.</p><p>Beckett, Samuel (Barclay) (b. April 13?, 1906, Foxrock, Co. Dub�  lin, Ire.�d.

Beckford and his family were forced to leave England for 10 years by a  scandal involving a youth.

Henri likewise studied phosphorescent  materials as well as uranium compounds and employed photography in  his experiments. He is remembered for his discovery of radioactivity,  which occurred when he found that the element uranium (in a sample of  pitchblende) emitted invisible rays that could darken a photographic plate.  His 1901 report of a burn caused by a sample of Marie Curie�s radium that  he carried in his vest pocket led to investigations by physicians and ulti�  mately the medical use of radioactive substances. In 1903 he shared a  Nobel Prize for Physics with the Curies. The unit of radioactivity, the  becquerel (Bq), is named for him.</p><p>bed Piece of furniture on which a person may recline or sleep.

Lamblike in appearance,  it has an arched back, a topknot, and  a thick, curly coat that is blue-gray,  deep reddish brown, or pale sandy,  often with tan markings. The breed  stands 15-16 in. (38-40 cm) tall and  weighs 22-24 lbs. (10-11 kg).</p><p>Bedouin \'bed-win\ Any member  of a community of Arabic-speaking  desert nomads of the Middle East.</p><p>Ethnically, the Bedouin are identical  to other Arabs. Bedouin traditionally  have made their living by animal  husbandry, and social rank among  them is determined by the animals  that they herd: camel nomads enjoy  the greatest status, followed by sheep  and goat herders and, finally, cattle  nomads. Traditionally, Bedouin  would migrate into the desert during  the rainy season and return to culti�  vated areas during the dry season,  but since World War II (1939�45) the  governments of many countries have  nationalized their range lands, and  conflicts over land use have arisen.</p><p>Many Bedouin have since adopted  sedentary ways of life; most, how�  ever, retain pride in their nomadic  heritage.</p><p>bedstraw Any low perennial her�  baceous plant of the genus Galium,  in the madder family, found in damp  woods and swamps and along stream banks and shores. Bedstraws bear  finely toothed, often needle-shaped leaves in whorls of four to eight; clus�  ters of small green, yellow, or white flowers; and fruit composed of two  rounded nuts joined together. Northern bedstraw (G. boreale ), marsh bed-  straw (G. palustre), and goosegrass (G. aparine) are common throughout  Europe and have become naturalized in parts of North America.

(2 mm-4 cm). Bees are  related to wasps, but, unlike wasps,  which can eat other insects, most  bees are entirely dependent on flow�  ers for their food. Male bees are usu�  ally short-lived and never collect  pollen; female bees make and provi�  sion the nest and usually have spe�  cial anatomical structures for  carrying pollen. Most species are  solitary. The so-called killer bee, an  Africanized subspecies of Apis mel-  lifera (see honeybee), reached the  U.S. from Mexico c. 1990; killer  bees react quickly and attack in number. See also Karl von Frisch.</p><p>bee balm Any of 12 North American annual or perennial plants in the  genus Monarda, variously known as bergamot, horsemint, and bee balm.  They belong to the mint family and have showy flowers. Wild bergamot  (M fistulosa ) has a minty aroma. The more sharply scented Oswego tea  (M didyma ; a bergamot variety) is native to eastern North America but  is widely cultivated elsewhere.</p><p>beech Any of several different types of trees, especially about 10 spe�  cies of deciduous ornamental and timber trees constituting the genus  Fagus (family Fagaceae), native to temperate and subtropical regions of  the Northern Hemisphere. About 40 species of superficially similar trees,  known as false beech (genus Nothofagus), are native to cooler regions of  the Southern Hemisphere. A beech of the family Fagaceae is tall, round-  headed, and wide-spreading, with smooth, steel-gray bark and toothed,  shiny green leaves. The American beech {F. grandifolia), native to east�  ern North America, and the European beech {F. sylvatica ), found through�  out England and Eurasia, are the most widely known species. Both are  economically important timber trees, often planted as ornamentals. Beech  wood is durable under water and is valued for indoor use, tool handles,  and shipping containers. The nuts provide forage for game animals, are  used in fattening poultry, and yield an edible oil. Beeches are slow-  growing and may live 400 years or more.</p><p>Beecham, Sir Thomas (b. April 29, 1879, St. Helens, Lancashire,  Eng.�d. March 8, 1961, London) British conductor. He was born to an  aristocratic family and was self-taught as a conductor. Devoted to broad�  ening British musical tastes, he created the Beecham Symphony Orches�  tra in 1909. In 1932 he founded the London Philharmonic Orchestra and  in 1947 the Royal Philharmonic Orchestra; he also founded opera com�  panies. Though he had significant gaps in his technique, he was an incom�  parable interpreter of the music he loved, especially that of Wolfgang  Amadeus Mozart; of his contemporaries, he particularly championed Rich�  ard Strauss and Frederick Delius.</p><p>Beecher, Catharine (Esther) (b. Sept. 6, 1800, East Hampton, N.Y.,  U.S.�d. May 12, 1878, Elmira, N.Y.) U.S. educator who popularized and  shaped a conservative movement to both elevate and entrench woman�s  role in the domestic sphere. Daughter of the minister and temperance  activist Lyman Beecher and sister of Harriet Beecher Stowe and Henry  Ward Beecher, she helped found the Hartford Female Seminary (1823) and  other organizations devoted to women�s education. Her popular Treatise  on Domestic Economy (1841) helped standardize domestic practices while  reinforcing the belief that a woman�s proper place was in the home.</p><p>Beecher, Henry Ward (b. June 24, 1813, Litchfield, Conn., U.S.�d.  March 8, 1887, Brooklyn, N.Y.) U.S. Congregational clergyman. The son  of a minister, he was the brother of Harriet Beecher Stowe and Catharine  Esther Beecher. After graduating from Amherst College and later studying at  Lane Theological Seminary, he served as pastor to congregations in Indi�  ana. In 1847 he was called to Plymouth Church in Brooklyn. A famous ora�  tor and one of the most influential preachers of his time, he opposed slavery  and supported women�s suffrage, Charles Darwin�s theory of evolution,</p><p>and scientific biblical criticism. He  gained unfavourable publicity in  1874 when he was put on trial for  adultery, but he was acquitted and  returned to his church.</p><p>bee-eater Any of about 25 species  of brightly coloured birds (family  Meropidae) that feed on bees, wasps,  and other insects. They are found  throughout tropical and subtropical  Eurasia, Africa, and Australasia (one  species occasionally reaches the  British Isles). Bee-eaters range in  length from 6 to 14 in. (15-35 cm).</p><p>Their bill is moderately long, slightly  downcurved, and pointed. Their bril�  liant plumage is usually predomi�  nantly green, but many species are  partially coloured with red, yellow,  blue, or purple.</p><p>beef Flesh of mature cattle, as dis�  tinguished from veal, the flesh of  calves. The best beef is obtained  from steers (castrated males) and  heifers (female cows that have not  calved). Tenderness and flavour are  improved by aging; in one common  method, the carcass is hung for about  two weeks at approximately 36 �F (2  �C). The world�s primary beef pro�  ducers and consumers are the U.S.,  the European Union, Brazil, China,</p><p>Argentina, and Australia. Grading  standards are relatively uniform; in  the U.S., grades range from prime  and choice to utility and canner. Beef  provides protein and B vitamins; it also contains saturated fat, an excess  of which can contribute to heart disease and other health problems. Beef  is not eaten by Hindus because of the sacred status of the cow.</p><p>beehive tomb or tholos \'tho-,las\ Large, beehive-shaped ceremo�  nial tomb, sometimes built into the side of a hill. The Treasury of Atreus,  a surviving tholos (c. 1300-1250 bc) of the Mycenaean civilization, is a  pointed dome built up of stepped blocks of conglomerate masonry cut  and polished to give the impression of a true vault. A small side chamber  contained the burials, while the main chamber was probably reserved for  ritual use.</p><p>beekeeping or apiculture Va-po-.kol-chorX Care and manipulation  of honeybees to enable them to produce and store more honey than they  need so that the excess can be collected. Beekeeping is one of the oldest  forms of animal husbandry. Early efforts at collecting the honey required  destroying the hive; modern beekeepers use an extractor that empties the  cells of the honeycomb without damaging them. To collect honey, bee�  keepers need a veiled helmet for protection, a tool for cutting comb, and  a smoker for tranquilizing the bees. Maintaining the hive includes pro�  tecting the colony against diseases, parasites, and predators.</p><p>beer Alcoholic beverage made usually from malted barley, flavoured with  hops, and brewed by slow fermentation. Known from ancient times, beer  was especially common in northern climates not conducive to grape cul�  tivation for wine. It is produced by employing either a bottom-fermenting  yeast, which falls to the bottom of the container when fermentation is  completed, or a top-fermenting yeast, which rises to the surface. Lager  beers (from lagern, �to store�), of German origin, are bottom-fermented  and stored at a low temperature for several months; most are light in  colour, with high carbonation, medium hop flavor, and alcohol content of  3-5% by volume. Top-fermented beers, popular in Britain, include ale,  stout, and porter; they are characterized by a prominent head of released  carbon dioxide, a sharper and more strongly hopped flavour than lagers,  and an alcohol content of 4-6.5% by volume.

Aug. 24, 1872, London,  Eng.�d. May 20, 1956, Rapallo, Italy) English caricaturist, writer, and  dandy. His sophisticated drawings and parodies were unique in capturing,  usually without malice, whatever was pretentious, affected, or absurd in  his famous and fashionable contemporaries. His first literary collection,  The Works of Max Beerbohm (1896), and his first book of drawings. Cari�  catures of Twenty-five Gentlemen (1896), were followed by the charming  fable The Happy Hypocrite (1897) and his only novel, Zuleika Dobson  (1911), a burlesque of Oxford life. His story collection Seven Men (1919)  is considered a masterpiece.</p><p>Beersheba City (pop., 1999 est.: 163,700), southern Israel. Historically  it marked the extreme southern limit of Palestine, hence the biblical phrase  �from Dan to Beersheba� (Dan is in far northern Israel). It fell to the Arabs  in the 7th century and to the Ottoman Empire in the 16th century. It was  long a watering place for the nomadic Bedouin tribes of the Negev desert.  Held by the British from 1917, it became part of Israel in 1948. It has  since developed as the administrative, cultural, and industrial centre of  the Negev.</p><p>Beery, Wallace (Fitzgerald) (b. April 1, 1885, Kansas City, Mo.,  U.S.�d. April 15, 1949, Los Angeles, Calif.) U.S. film and stage actor.  He initially worked in the circus and later in the choruses of New York  City theatrical productions. After playing the lead in The Yankee Tourist,  he spent several years as a dramatic actor in touring and stock companies.  He started his film career in 1913, first as a comedian in Mack Sennett�s  Keystone comedies. He is best known for his performances as dim-witted,  but endearing, toughs in such films as The Champ (1931, Academy  Award), Min and Bill (1931), and Tugboat Annie (1933).</p><p>beeswax Commercially useful wax secreted by worker honeybees to  make the cell walls of the honeycomb. A bee consumes an estimated 6-10  lbs (3-4.5 kg) of honey for each pound of the wax it secretes in small  flakes from glands on the underside of its abdomen. After honey removal,  the comb is melted to produce the beeswax, which ranges from yellow  to almost black. It is used for candles (often for churches), artificial fruit  and flowers, modeling wax, and as an ingredient of furniture and floor  waxes, leather dressings, waxed paper, lithographic inks, cosmetics, and  ointments.</p><p>beet Cultivated form of the plant Beta vulgaris of the goosefoot family  (Chenopodiaceae), one of the most  important vegetables. Four distinct  types are cultivated: the garden beet,  as a garden vegetable; the sugar beet,  a major source of sugar and commer�  cially the most important type; the  mangel-wurzel, a succulent feed for  livestock; and the leaf beet, or Swiss  chard, for its edible leaves. Beet  greens are a source of riboflavin,  iron, and vitamins A and C. Beets are  grown most extensively in temperate  to cool regions or during the cooler  seasons.</p><p>Beethoven Vba-.to-vonX, Lud�  wig van (baptized Dec. 17, 1770,</p><p>Bonn, archbishopric of Cologne�d.</p><p>March 26, 1827, Vienna, Austria)</p><p>German composer. Born to a musi�  cal family, he was a precociously  gifted pianist and violist. After nine years as a court musician in Bonn,  he moved to Vienna to study with Joseph Haydn and remained there for  the rest of his life. He was soon well known as both a virtuoso and a  composer, and he became the first important composer to earn a success�  ful living while forsaking employment in the church or court. He uniquely  straddled the Classical and Romantic eras. Rooted in the traditions of  Haydn and Mozart, his art also encompassed the new spirit of humanism  expressed in the works of German Romantic writers as well as in the ide�</p><p>als of the French Revolution, with its passionate concern for the freedom  and dignity of the individual. His astonishing Third ( Eroica ) Symphony  (1803) was the thunderclap that announced the Romantic century, and it  embodies the titanic but rigorously controlled energy that was the hall�  mark of his style. He began to lose his hearing from c. 1795; by c. 1819  he was totally deaf. For his last 15 years he was unrivaled as the world�s  most famous composer. In musical form he was a considerable innova�  tor, widening the scope of sonata, symphony, concerto, and string quar�  tet. His greatest achievement was to raise instrumental music, hitherto  considered inferior to vocal, to the highest plane of art. His works include  the celebrated 9 symphonies; 16 string quartets; 32 piano sonatas; the  opera Fidelio (1805, rev. 1814);2 masses, including the Missa Solemnis  (1823); 5 piano concertos; a violin concerto (1806); 6 piano trios; 10 vio�  lin sonatas; 5 cello sonatas; and several concert overtures.</p><p>beetle Any of at least 250,000 species of insects constituting the order  Coleoptera (the largest order in the animal kingdom), characterized by  special forewings, called elytra, which are modified into hardened covers  over a second pair of functional wings. Beetles occur in almost all envi�  ronments except Antarctica and the peaks of the highest mountains. Tem�  perate zones have fewer beetle species than the tropics but in greater  numbers. The smallest species are less than 0.04 in. (1 mm) long; the  largest can exceed 8 in. (20 cm). Most beetles eat either other animals or  plants; some eat decaying matter. Some species destroy crops, timber, and  textiles and spread parasitic worms and diseases. Others are valuable  predators of insect pests. Some beetles are known by other common  names (e.g., borer, chafer, curculio, firefly, weevil). Beetles are preyed on  by other insects and by bats, swifts, and frogs.</p><p>Begin \be-'gen,\ English \'ba-gin\, Menachem (Wolfovitch) (b.</p><p>Aug. 16, 1913, Brest-Litovsk,</p><p>Russia�d.

From  1948 to 1977 he led the opposition  in the Israeli Knesset, except for  three years when he sat in the Gov�  ernment of National Unity (1967-  70). As head of the Likud party  coalition, he became prime minister  in 1977. He shared the 1978 Nobel  Prize for Peace with Anwar el-Sadat  for negotiations that resulted in the 1979 Israel-Egypt peace treaty.

Bego�  nias come in a bewildering array of cultivated varieties. The wax begonia  ( B. semperfiorens) is the most popular for use as a summer bedding plant;  angelwing begonias are characterized by their tall stems; hairy begonias  have feltlike leaves.

Borstal Boy (1958) is  an account of his detention in an English reform school, which combines  earthy satire and powerful political commentary. His first play. The Quare  Fellow { 1954), is an explosive statement on capital punishment and prison  life. His second, The Hostage (produced 1958), is considered his master-  work.

The first sci�  entist to explore the area was Sir Francis Galton, who sought to show that  mental powers run in families. His work was followed by huge numbers  of studies seeking to establish a link between IQ and genetics, none of  them conclusive. Other human characteristics or behaviours studied for  their possible hereditary nature include schizophrenia, alcoholism, depres�  sion, introvert and extravert behaviour, and general activity level (includ�  ing sleep disorders). Many such studies are based on long-term  observation of identical (monozygotic) twins raised in different environ�  ments. In animal studies, which examine topics such as learning, sexual  activity, and aggressive behaviour, selective breeding is used to produce  groups of genetically similar individuals that may be compared with other,  dissimilar individuals or groups. See also human nature.</p><p>behaviour therapy or behaviour modification Application of  experimentally derived principles of learning to the treatment of psycho�  logical disorders and the control of behaviour. The concept, which has its  roots in the work of Edward L. Thorndike, was popularized in the U.S. by  theorists of behaviourism, including B.F. Skinner. Behaviour-therapy tech�  niques are based on the principle of operant conditioning, in which desired  behaviours are rewarded. There is little or no concern for conscious expe�  rience or unconscious processes. Such techniques have been applied with  some success to disturbances such as enuresis, tics, phobias, stuttering,  obsessive-compulsive disorder, and various neuroses. Behaviour modification  more generally refers to the application of reinforcement techniques for  shaping individual behaviour toward some desired end or for controlling  behaviour in classrooms or institutional situations. See also psychotherapy.</p><p>behaviourism Highly influential academic school of psychology that  dominated psychological theory in the U.S. between World War I and  World War 11. Classical behaviourism concerned itself exclusively with  the objective evidence of behaviour (measured responses to stimuli) and  excluded ideas, emotions, and inner mental experience (see conditioning).  It emerged in the 1920s from the work of John B. Watson (who borrowed  from Ivan Pavlov) and was developed in subsequent decades by Clark L.  Hull and B.F. Skinner. Through the work of Edward C. Tolman, strict behav�  iourist doctrines began to be supplemented or replaced by those admit�  ting such variables as reported mental states and differences in perception.  A natural outgrowth of behaviourist theory was behaviour therapy.</p><p>Behn Vban\, Aphra (b. July 1640, Harbledown?, Kent, Eng.�d. April  16, 1689, London) English dramatist, novelist, and poet, the first English�  woman known to earn her living by writing. Her early life is obscure (as is  her original surname), but she spent most of it in South America. She mar�  ried a merchant named Behn in 1658; he died in the mid 1660s. Her novel  Oroonoko (1688), the story of an enslaved African prince whom Behn  knew in South America, influenced the development of the English novel.  Her first play. The Fore �d Marriage, was produced in 1671; her later witty  comedies, such as the two-part The Rover (1677, 1681), were highly suc�  cessful, and toward the end of her life she wrote many popular novels.</p><p>Behrens \'ba-rens\, Peter (b. April 14, 1868, Hamburg�d. Feb. 27,  1940, Berlin, Ger.) German architect  and designer. He became director of  Diisseldorf�s arts and crafts school in  1903. The large electrical company  AEG hired him in 1907 as its artis�  tic adviser, a comprehensive job that  led him to design the hexagonal  trademark of the AEG, its catalogs,  its office stationery, products such as  electric fans and street lamps, and  retail shops and factories. His AEG  Works turbine factory in Berlin  (1909-12), with its sweeping glass  curtain wall, became the most sig�  nificant building in Germany at that  time.

The munici�  pality is bordered by Hebei province and Tianjin municipality and has an  area of 6,500 sq mi (16,800 sq km). Lying on a broad plain in northeast�  ern China, the city has been settled since ancient times and has been  known by various names. It became the royal residence of Kublai Khan,  who in 1272 named it Dadu. It was chosen as the capital of the Ming  dynasty (1368-1644) in 1421, which it remained during the Qing dynasty  (1644�1911/12). It suffered heavy damage when it was occupied by Euro�  pean forces in 1860 and 1900 (see Boxer Rebellion). In 1928 the capital  was moved to Nanjing, and the name Beiping (Pei-p�ing) was given to  the former capital. Nearby, in 1937, the Marco Polo Bridge Incident took  place. Beijing�s capital status and its former name were restored follow�  ing the communist victory in 1949. It is China�s cultural and educational  centre. The old Forbidden City contains the former imperial palace, desig�  nated a UNESCO World Heritage site in 1987. Abutting it is Tiananmen  Square, one of the world�s largest public squares.

In 1959 it moved to Brussels; renamed  the Ballet of the 20th Century, it became one of the world�s foremost  troupes. His productions have been noted for reworking tradition in  unusual and often controversial ways. Since 1961 he has also worked in  opera, staging Tales of Hoffmann and Berlioz�s Damnation of Faust ,  among other works. In 1987 the company moved to Switzerland and took  the new name Bejart Ballet Lausanne.</p><p>Bejart \ba-'zhar\ family Seventeenth-century French theatrical family.  Brothers Joseph (c. 1617-59) and Louis (1630-78) and their sisters  Madeleine (1618-72) and Genevieve (c. 1622-75) were members of a  traveling company directed by Madeleine. They joined Moliere�s first  company, the Illustre Theatre, in 1643 and created many parts in his plays.  Madeleine�s sister, or possibly daughter, Armande Bejart (1642-1700),  joined the company in 1653. She married Moliere in 1662 and played  most of his heroines. After his death, she led the company until it merged  with another troupe to become the Comedie-Francaise in 1680.</p><p>Bekesy \'ba-,ka-she\, Georg von (b. June 3, 1899, Budapest,  Hung.�d. June 13, 1972, Honolulu, Hawaii, U.S.) Hungarian-born U.S.  physicist and physiologist. He immigrated to the U.S. in 1947 and taught  at Harvard University in 1947-66. He discovered that sound vibrations  travel along a membrane in the cochlea in waves, peaking at different  places, where nerve receptors determine pitch and loudness. His research  resulted in greatly expanded understanding of the hearing process, partly  through instrumentation Bekesy had helped design, and the differentia�  tion of forms of deafness, which permitted the selection of proper treat�  ment. He received a 1961 Nobel Prize for Physiology or Medicine.</p><p>Bekhterev Vbyak-tir-yif\, Vladimir (Mikhaylovich) (b. Feb. 1,  1857, Sorali, Vyatka, Russia�d.

His most lasting work was in brain structure research and  descriptions of nervous symptoms and illnesses. He discovered the supe�  rior vestibular nucleus (Bekhterev nucleus) and other brain formations and  described spinal numbness (spondylitis deformans, or Bekhterev disease)  and other diseases. He founded the first Russian journal on nervous dis�  eases. His approach to the study of behaviour influenced the growing  movement toward behaviourism in the U.S.</p><p>Bel Akkadian god of the atmosphere and member of a triad including  Anu (An) and Ea (Enki).

Area: 80,200 sq mi (207,600 sq km).  Population (2005 est.): 9,776,000. Capital: Minsk. The population is  mainly Belarusian, with Russian and Ukrainian minorities. Languages:  Belarusian, Russian (both official). Religion: Christianity (predominantly  Eastern Orthodox; also Roman Catholic). Currency: rubel. The northern</p><p>part of the country is crossed by the West�  ern Dvina (Dzvina) River; the Dnieper  (Dnyapro) flows through eastern Belarus;  the south has extensive marshy areas along  the Pripet (Prypyats�) River; the upper  course of the Neman (Nyoman) flows in the west; and the Bug (Buh) forms  part of the boundary with Poland in the southwest. The chief cities, in  addition to Minsk, are Homyel, Mahilyow, and Vitsyebsk. Agriculture, once  the linchpin of the Belarusian economy, has diminished in importance,  while manufacturing and the service sector have grown. Belarus is a  republic with two legislative houses; its president is head of state and  government. Although Belarusians share a distinct identity and language,  they never previously enjoyed political sovereignty. The territory that is  now Belarus underwent partition and changed hands often; as a result, its  history is entwined with its neighbours�. In medieval times the region was  ruled by Lithuanians and Poles. Following the Third Partition of Poland,  Belarus was ruled by Russia. After World War I the western part was  assigned to Poland, and the eastern part became Soviet territory. After  World War II the Soviets expanded what had been the Belorussian S.S.R.  by annexing more of Poland. Much of the area suffered radioactive con�  tamination from the Chernobyl accident in 1986, which forced many to  evacuate. Belarus declared its independence in 1991 and later joined the  Commonwealth of Independent States. Amid increasing political turmoil in  the 1990s, it moved toward closer union with Russia but continued to  struggle economically and politically at the start of the 21st century.</p><p>Belarusian X.bya-b-'rU-se-onV language or Belarusan</p><p>\ l bya-b- , riis-3n\ language East Slavic language of Belarus, spoken by  some 10.2 million people worldwide. Belarusian features begin to appear  in Church Slavonic manuscripts from the 14th century (see Old Church  Slavonic language). The chancery language of the grand duchy of Lithua�  nia, used in the 15th�16th centuries, contains a substantial Belarusian ele�  ment, mixed with Church Slavonic, Ukrainian, and Polish. Belarusian was  not fully elaborated as a modern literary language until the early 20th  century, when orthographic norms for writing it in Cyrillic were estab�  lished. It has long struggled to maintain itself against Russian, particularly  in Belarusian urban centres, where there is a high degree of Russification  and Belarusian-Russian bilingualism.</p><p>Belasco \b9-'las-ko\, David (b.

Bel�  fast�s modern history began in the early 17th century when Sir Arthur  Chichester developed a plan for colonizing the area with English and  Scottish settlers. Having survived the Irish insurrection of 1641, the town  grew in economic importance, especially after a large immigration of  French Huguenots arrived after the rescinding of the Edict of Nantes  (1685) and strengthened the linen trade. It became a centre of Irish Prot�  estantism, setting the stage for sectarian conflict in the 19th-20th centu�  ries. Fighting was renewed in the 1960s and did not subside until a peace  agreement was reached in 1998. The city is Northern Ireland�s educational  and commercial hub.</p><p>belfry Bell tower, either freestanding or attached to another structure.

Languages:  Dutch, French, German (all official). Reli�  gions: Christianity (predominantly Roman Catholic); also Islam. Cur�  rency: euro. Belgium can be divided into several geographic regions. The  southeast consists of the forested Ardennes highland, which extends south  of the Meuse River valley and includes Belgium�s highest point, Mount  Botrange (2,277 ft [694 m]). Middle Belgium is a fertile region crossed  by tributaries of the Schelde River. Lower Belgium comprises the flat plains  of Flanders in the northwest with their many canals. Maritime Flanders  borders the North Sea and is agriculturally prosperous; the chief North  Sea port is Ostende, but Antwerp, near the mouth of the Schelde, handles  more trade. Belgium has minimal natural resources, so the manufacture  of goods from imported raw materials plays a major role in the economy,  and the country is highly industrialized. It is a monarchy with a parlia�  ment composed of two legislative houses; the chief of state is the mon�  arch, and the head of government is the prime minister. Inhabited in  ancient times by the Belgae, a Celtic people, the area was conquered by  Julius Caesar in 57 bc; under Augustus it became the Roman province of  Belgica. Conquered by the Franks, it later broke up into semi-independent  territories, including Brabant and Luxembourg. By the late 15th century the  territories of the Netherlands, of which the future Belgium was a part,  gradually united and passed to the Habsburgs. In the 16th century it was  a centre for European commerce. The basis of modern Belgium was laid  in the southern Catholic provinces that split from the northern provinces  after the Union of Utrecht in 1579 (see The Netherlands). Overrun by the  French and incorporated into France in 1801, the area was reunited with  Holland and with it became the independent Kingdom of The Netherlands  in 1815. After the revolt of its citizens in 1830, it became the indepen�  dent Kingdom of Belgium. Under Leopold II it acquired vast lands in  Africa. Overrun by the Germans in World Wars I and II, it was the scene  of the Battle of the Bulge (1944-45). Internal discord led to legislation in  the 1970s and �80s that created three nearly autonomous regions in accor�  dance with language distribution: Flemish Flanders, French Wallonia, and  bilingual Brussels. In 1993 Belgium became a federation comprising the  three regions, which gained greater autonomy at the outset of the 21st  century. It is a member of the European Union.</p><p>Belgrade Serbian Beograd \ba-'6-,grad\ City (pop., 2002:  1,120,092), capital of the republic of Serbia and administrative centre of  Serbia and Montenegro.

It became the capital of the kingdom of Serbia in 1867 and, after  World War I, of the new Kingdom of Serbs, Croats, and Slovenes  (renamed Yugoslavia in 1929). It suffered severely under Nazi occupation  (1941�44). It was damaged by NATO bombers in the Kosovo conflict  (1999).

In 532 Belisarius further gained Jus�  tinian�s confidence by commanding the troops that ended the Nika Insur�  rection that nearly toppled the emperor. He led expeditions to overthrow  the Vandals in North Africa (533) and regain Sicily and southern Italy  from the Ostrogoths (535-537), defending Rome (537-538). He was  offered a kingship by the Goths, which caused Justinian to recall him in  disfavour. He was sent again to Rome (544-548) but with inadequate  forces, and he was replaced by Narses in 548.

Languages: English (official), Cre�  ole, Spanish. Religion: Christianity (Roman Catholic, Protestant).  Currency: Belize dollar. The country is bounded to the north by Mexico,  to the east by the Caribbean Sea, and to the west and south by Guatemala.  Belize is a land of mountains, swamps, and tropical jungles. The north�  ern half consists of swampy lowlands drained by the Belize and Hondo  rivers; the latter forms the boundary with Mexico. The southern half is  more mountainous and contains the country�s highest point, Victoria Peak  (3,681 ft [1,122 m]). Off the coast lies Belize Barrier Reef, the world�s  second largest barrier reef. Belize is relatively prosperous and has a devel�  oping free-market economy with some government participation. It is a  constitutional monarchy with two legislative houses; its head of state is  the British monarch represented by a governor-general, and the head of  government is the prime minister. The area was inhabited by the Maya  (c. 300 bc-ad 900); the ruins of their ceremonial centres, including Car-  acol and Xunantunich, can still be seen. The Spanish claimed sovereignty  from the 16th century but never tried to settle Belize, though they regarded  the British who did as interlopers. British loggers arrived in the mid-17th  century; Spanish opposition was finally overcome in 1798. When settlers  began to penetrate the interior, they met with Indian resistance. In 1871  British Honduras became a crown colony, but an unfulfilled provision of  an 1859 British-Guatemalan treaty led Guatemala to claim the territory.  The situation had not been resolved when Belize was granted its inde�  pendence in 1981. Although Guatemala officially recognized the territo�  ry�s independence in 1991, a British force, stationed there to ensure the  new country�s security, was not withdrawn until 1994.</p><p>Belize City City (pop., 2000: 49,050), Belize.

The British settled the area in the 17th century. The city, built on  ground only slightly above sea level, has been ravaged by hurricanes, so  the capital was moved inland to Belmopan in 1970.</p><p>bell Hollow vessel, usually of metal, that produces a ringing sound when  struck by an interior clapper or a mallet.

He moved  to the U.S. in 1871 to teach the  visible-speech system developed by  his father, Alexander Melville Bell  (1819-1905). He opened his own  school in Boston for training teach�  ers of the deaf (1872) and was influ�  ential in disseminating these  methods. In 1876 he became the first  person to transmit intelligible words  through electric wire (�Watson,  come here, I want you,� spoken to  his assistant Thomas Watson). He  patented the telephone the same year,  and in 1877 he cofounded Bell Tele�  phone Co. With the proceeds from  France�s Volta Prize, he founded  Volta Laboratory in Washington,</p><p>D.C., in 1880. His experiments there  led to the invention of the photo�  phone (which transmitted speech by  light rays), the audiometer (which measured acuteness of hearing), the  Graphophone (an early practical sound recorder), and working wax  recording media, both flat and cylindrical, for the Graphophone.

He wrote his first opera at age 24  and went on to complete nine more before his death at age 33. The most  famous are The Pirate (1827), The Capulets and the Montagues (1830),  The Sleepwalker (1831), Norma (1831), and The Puritans (1835). His  works, which rely strongly on beautiful vocal melody ( hel canto), rivaled  those of his contemporaries Gioacchino Rossini and Gaetano Donizetti in  popularity.</p><p>Bellini \bal-'le-ne\ family Family of Italian artists. Jacopo Bellini (c.  1400-70/71) was trained under Gentile da Fabriano, and by c. 1440 he had  a thriving studio in Venice. More important than his paintings are his two  surviving sketchbooks, which contain nearly 300 drawings. He was the  father-in-law of Andrea Mantegna. His son Gentile Bellini (c. 1429-1507)  inherited his father�s sketchbooks and took over as head of the studio. His  most important extant works are two huge canvases. Procession of the  Relic of the True Cross (1496) and Miracle at the Bridge of San Lorenzo  (1500), depicting scenes of contemporary Venetian life. Gentile�s brother  Giovanni Bellini (called Giambellino, c. 1430-1516) was the greatest and  most prolific artist of the family. He transformed Venice into a Renais�  sance centre rivaling Florence and Rome. Giovanni was an early master  of oil painting. Primarily a religious painter, he also excelled at portraits,  of which Doge Leonardo Loredan (c. 1501) is his best known. Titian and  Giorgione were probably trained in his workshop.

A  highly versatile writer, he is best remembered for his light verse, particu�  larly for children, and for his lucid and graceful essays. His works include  Verses and Sonnets (1895), The Bad Child�s Book of Beasts (1896), The  Modern Traveller (1898), Mr. Burden (1904), and Cautionary Tales  (1907).

In 1747 he left Italy to spend the rest of his life working at various  European courts, most notably at Dresden for Frederick Augustus II  (1747-66) and at Warsaw for Stanislaw II (1767-80). His detailed views  of the Polish capital were used as guides to reconstruct the historic sec�  tions of the city after their destruction in World War II.

His family moved to Chicago when he was nine; he grew up  and attended college there and, after some years in New York, returned  to teach in Chicago. His works, which make him representative of the  Jewish American writers whose works became central to American lit�  erature after World War II, deal with the modern urban dweller, disaf�  fected by society but not destroyed in spirit; his originality lay partly in  his combination of cultural sophistication and street wisdom.

Introduced to  Zionism by his father, Ben-Gurion immigrated to Palestine, then part of  the Ottoman Empire, in 1906, hoping to fulfill the Zionist aspiration of  building a Jewish state in historic Israel. Expelled by the Ottomans at the  outbreak of World War I (1914-18), he traveled to New York, where he  married. Following the issuance of the Balfour Declaration, he joined the  British army�s Jewish Legion and returned to the Middle East. In the  1920s and �30s he led several political organizations, including the Jew�  ish Agency, world Zionism�s highest directing body. As Britain became  more sympathetic to the interests of the Palestinian Arabs, thereafter  restricting Jewish immigration to Palestine, he called on the Jewish com�  munity to rise against Britain. However, he again called for Jews to sup�  port the Allies during World War II (1939-45), while continuing the  clandestine immigration of Jews to Palestine. On the establishment of the  State of Israel (1948), he became prime minister and minister of defense.  He succeeded in fusing the underground Jewish militias that had fought  the British into a national army, which he used successfully to defend  against Arab attacks. Unpopular with Britain and the U.S., he found an  ally in France�then embroiled in its own war in the Arab world�which  helped arm Israel in the period leading to the Suez Crisis (1956).

The Rule  includes a probationary year prior to the vow of obedience and lifelong  residence at one monastery, a ban on personal property, an abbot elected  for life who appoints all other officers, and a precisely ordered day that  includes five to six hours of liturgy and prayer, five hours of manual work,  and four hours of scriptural and spiritual reading.</p><p>Benedict XII orig. Jacques Fournier (b. Saverdun, near Toulouse,  France�d. April 25, 1342, Avignon, Provence) Pope (1334-42). A French  cardinal and theologian, he became the third pontiff to reign at Avignon  (see Avignon papacy), succeeding John XXII. The bishop of Pamiers and  Mirepoix and a zealous inquisitor before his elevation to the papacy,  Benedict devoted himself to the reform of the church and its religious  orders; he also tried unsuccessfully to prevent the outbreak of the conflict  between England and France that became the Hundred Years' War. His  bull Benedictus Deus (1336) set forth the doctrine of the beatific vision  as a vision of God granted to the souls of the just immediately after death.</p><p>Benedict XIII orig.

Elected  pope at Avignon (see Avignon papacy), he refused French pressure to abdi�  cate and was besieged in the papal palace (1398). Benedict escaped to  Provence in 1403 and won back the obedience of France. He refused to  yield when deposed by the Councils of Pisa (1409) and Constance (1417).</p><p>Benedict XIV orig. Prospero Lambertini (b. March 31, 1675,  Bologna, Papal States�d. May 3, 1758, Rome) Pope in 1740-58. Nobly  bom, he received a doctorate in theology and law. Typical of his pontifi�  cate were his promotion of scientific learning and his admonition to those  drawing up the Index Librorum Prohibitorum (Index of Forbidden Books)  to act with restraint. In the Papal States he reduced taxation, encouraged  agriculture, and supported free trade. He maintained conciliatory relations  with neighbouring kingdoms. A lifelong active scholar, he founded sev�  eral learned societies and laid the groundwork for the present Vatican  Museum. Bernard Gamier, a French cleric who was counter-antipope  (1425-33) while Martin V was pope and Clement VIII was antipope, was  also called Benedict XIV.</p><p>Benedict XV orig.

He was  made archbishop of Bologna in 1907  and cardinal in 1914. Elected pope a  month after the outbreak of World  War I, he tried to follow a policy of  strict neutrality and concentrated the  church�s efforts on relief. He later  made positive efforts toward reestab�  lishing peace, though his principal  attempt in 1917 to mediate the war  was unsuccessful.</p><p>Benedict XVI orig. Joseph  Alois Ratzinger (b.

He was ordained in 1951  and received a doctorate in theology  at the University of Munich in 1953.</p><p>Thereafter he pursued a career as a  theologian and teacher at various  universities. During the Second Vat�  ican Council (1962-65) he served as  an expert adviser and an advocate of  reform. In 1977 he was appointed  archbishop of Munich; three months  later he was made a cardinal. As pre�  fect of the Congregation for the Doc�  trine of the Faith from 1981 to 2005,  he enforced doctrinal uniformity in  the church and served as a close  adviser of Pope John Paul II. He was  faced with numerous challenges  when he became pope, including a  decline in church attendance and in  the number of new priests, deep divi�  sions over the direction of the  church, and the lingering effects of a  sexual-abuse scandal involving priests in various parts of the world.</p><p>Benedictine Member of the Order of St. Benedict, the confederated  autonomous congregations of monks and lay brothers who follow the  Benedictine Rule, created by St. Benedict of Nursia in the 6th century. The  Rule spread slowly in Italy and Gaul. By the 9th century it was nearly  universal in northern and western Europe, where Benedictine monaster�  ies became repositories of learning, literature, and wealth. The order  declined during the 12th�15th century, when it was revived with reforms  that limited abbots to fixed terms and required monks to make their vows  to the congregation rather than a particular house. The Reformation vir�  tually eliminated Benedictines from northern Europe, and they declined  elsewhere. In the 19th century another revival strengthened the order in  Europe, especially in France and Germany, and led to the establishment  of new congregations worldwide.</p><p>benefice Vbe-ns-fasV System of land tenure first used by the Franks  during the 8th century. A Frankish lord leased an estate to a freeman in  beneficium (Latin: �for the benefit (of the tenant)�), normally until the  death of the lord or tenant, though tenants often succeeded in turning ben�  efices into hereditary holdings. By the 12th century benefice was dying  out as a term for land tenure; instead it referred to a church office that  carried with it the right of receiving income. A lord or bishop chose a  priest, who was granted the benefice in return for the performance of  spiritual duties.</p><p>beneficiary \ 1 be-n9-'fi-she- l er-e, .be-no-'fi-sho-reV Person or entity  (e.g., a charity or estate) that receives a benefit from something (e.g., a  trust, life-insurance policy, or contract). A primary beneficiary receives  proceeds from a trust or insurance policy before any other. A contingent  beneficiary receives proceeds upon the occurrence of a specified event,  such as the death of the primary beneficiary. A direct beneficiary is a third  party whom contracting individuals intend to benefit from a contract; an  incidental beneficiary benefits without that being the contracting indi�  viduals� intention.</p><p>beneficiation V.be-no-.fi-she-'a-shonX Treatment of raw material (such  as pulverized ore) to improve physical or chemical properties in prepa�  ration for further processing.

He served as its first foreign minister (1918-35)  and its president (1935-38). Forced to capitulate to Adolf Hitler�s demands  over the Sudetenland, he resigned. He headed the Czech government-in�  exile in England (1940-45), then reestablished a government on his native  soil in 1945.

Benet is best known for John Brown�s Body (1928, Pulitzer  Prize), a long narrative poem on the American Civil War. A Book of  Americans (1933), poems written with his wife, the former Rosemary  Carr, brought many historical characters to life for American schoolchil�  dren.

Gener�  ally corresponding to the area inhabited by speakers of the Bengali lan�  guage, it is now divided between eastern India and Bangladesh. Bengal  formed part of most of the early empires that controlled northern India.  From the 8th to the 12th century it was under a Buddhist dynasty, and  from 1576 it belonged to the Mughal Empire. In the 18th century it was  dominated by the nawabs of Bengal; they came into conflict with the  British, who had established themselves at Calcutta (now Kolkata) in  1690. By 1764 the British had taken possession, and Bengal became the  base for British expansion in India. Bengal was partitioned in 1905, and  with the end of British rule in 1947, the western portion formed the Indian  states of West Bengal, Bihar, and Orissa. East Bengal went to Pakistan;  in 1971 it became Bangladesh. Jharkhand state was created from south�  ern Bihar in 2000.</p><p>Bengal, Bay of Part of the Indian Ocean.

The British province of Bengal, which  also included Bihar and Orissa, had by the beginning of the 20th century  grown too large to handle under a single administration. Curzon chose to  unite eastern Bengal with Assam, leaving western Bengal with Bihar and  Orissa. The partition went through despite widespread protests, unrest,  and boycotts, but in 1911 eastern and western Bengal were reunited.  Assam resumed its old status, and Bihar and Orissa were separated to form  a new province.</p><p>Bengali \ben-'ga-le\ language Indo-Aryan language spoken princi�  pally in Bangladesh and the Indian state of West Bengal.

The Fon people and related groups  constitute two-fifths of the population;  minorities include the Yoruba, Fulani, and  Adjara. Languages: French (official), Fon.</p><p>Currency: CFA franc. Religions: tradi�  tional religions, Islam, Christianity. Extending about 420 mi (675 km)  inland from the Gulf of Guinea, Benin includes a hilly region in the north�  west, where the maximum elevation is 2,103 ft (641 m). There are plains  in the east and north and a marshy region in the south, where the coastline</p><p>extends about 75 mi (120 km). Benin�s longest river, the Oueme, flows  into the Porto-Novo Lagoon and is navigable for 125 mi (200 km) of its  280-mi (450-km) length. Benin has a developing mixed economy based  largely on agriculture and operates an offshore oil field. It is a republic  with one legislative house; the head of state and government is the presi�  dent, assisted by the prime minister. In southern Benin the Fon established  the Abomey kingdom in the early 17th century. In the 18th century the  kingdom expanded to include Allada and Ouidah, where French forts had  been established in the 17th century. By 1882 the French were firmly rees�  tablished in the area, and conflict between the French and Africans ensued.  In 1894 Dahomey became a French protectorate; it was incorporated into  the federation of French West Africa in 1904. It achieved independence in  1960. Dahomey was renamed Benin in 1975. Its chronically weak  economy created problems for the country into the 21st century.</p><p>Benin, Bight of Bay, northern section of Gulf of Guinea. It extends  along the West African coast about 400 mi (640 km) from Cape St. Paul,  Ghana, past Togo and Benin to an outlet of the Niger River in Nigeria.  Major ports include Lome, Cotonou, and Lagos. It was the scene of exten�  sive slave trading during the 16th-19th century, and the region of coastal  lagoons west of the Niger delta became known as the Slave Coast. By the  1830s trade in palm oil had become the major economic activity. Petro�  leum was discovered in the Niger delta in the 1950s.</p><p>Benin, kingdom of One of the principal historic kingdoms (12th�19th  century) of the western African forest region. Founded by the Edo people,  the kingdom was centred on present-day Benin City in southern Nigeri-  a.With the accession of Ewuare the Great in the mid 15th century, the  Benin kingdom was vastly expanded, including the founding of the city  of Lagos. The Portuguese first visited Benin in the late 15th century, and,  for a time, Benin traded ivory, palm oil, pepper, and slaves with Portu�  guese and Dutch traders. Benin stopped trading slaves with Europeans in  the 18th century and focused attention on dependent regions around it.  Succession struggles in the 18th and 19th centuries put a series of weaker  kings on the throne. After the British attacked and burned Benin City in  1897, the kingdom was incorporated into British Nigeria.</p><p>Benjamin, Judah P(hilip) (b.</p><p>Islands�d.

March 14, 1782, near Hillsborough, N.C.,  U.S.�d. April 10, 1858, Washing�  ton, D.C.) U.S. politician. After  moving to St. Louis, Mo. (1815), he  became editor of the St. Louis  Enquirer. Appealing to agrarian and  commercial interests, he won elec�  tion to the U.S. Senate in 1820. He  became a crusader for the distribu�  tion of public lands to settlers and  was soon acknowledged as the chief  spokesman in the Senate of the early  Democratic Party. His opposition to  the extension of slavery into the West  cost him his Senate seat in 1851,  though he later served in the House  of Representatives (1853-55). His  grandnephew was the artist Thomas  Hart Benton.</p><p>Benton, Thomas Hart (b. April</p><p>15, 1889, Neosho, Mo., U.S.�d. Jan. 19, 1975, Kansas City, Mo.) U.S.  painter and muralist. He studied at the Art Institute of Chicago and at the  Academie Julian in Paris, where he came into contact with Synchromism  and Cubism. In 1912 he returned to the U.S. and settled in New York City.  Failing in his attempts at Modernism, he set out to travel through the rural  heartland, sketching people and places. In the 1930s he painted several  notable murals, including America Today (1930-31) at the New School  for Social Research. He often transposed biblical and classical stories to  rural American settings, as in Susanna and the Elders (1938). His style,  which quickly became influential, is characterized by undulating forms,  cartoonlike figures, and brilliant colour. He taught at the Art Students  League in New York, where Jackson Pollock was his best-known student.</p><p>Benton, William (Burnett) (b. April 1, 1900, Minneapolis, Minn.,  U.S.�d.

A descendant of missionaries and edu�  cators, he founded, with Chester Bowles, the successful New York adver�  tising agency of Benton &amp; Bowles. He later became a vice president of the</p><p>University of Chicago; through his efforts, the university acquired Ency�  clopaedia Britannica, which he managed and later purchased. In 1945 he  became assistant secretary of state, and he later briefly served in the U.S.  Senate (1949-52). Thereafter he devoted sustained attention to the ency�  clopaedia; he died shortly before the publication of its 15th edition.</p><p>bentwood furniture Type of furniture made of wooden rods bent into  shape after being heated with steam.</p><p>The method was used on the 18th-  century Windsor chair, but its prin�  cipal exponent was Michael Thonet,  who exploited its possibilities in the  1840s.

The original car, his three-wheeled Motor-  wagen, first ran in 1885. Benz�s company produced its first four-wheeled  car in 1893 and the first of its series of racing cars in 1899. Benz left the  company in 1906 to form another group with his sons. In 1926 the Benz  company merged with the company started by Gottlieb Daimler.</p><p>benzene Simplest aromatic hydrocarbon (see aromatic compound), par�  ent substance of a large class of chemical compounds. It was discovered  in 1825 by Michael Faraday. The chemical formula is C 6 H 6 ; August Kekule  von Stradonitz in 1865 was the first to propose the correct structure, a  six-membered ring of carbon atoms, each with one hydrogen atom bonded  to it (see bonding). Although benzene is often represented with alternat�  ing single and double bonds between carbon atoms, the electrons in the  bonds are shared or delocalized in such a way as to make all carbon-  carbon bonds alike. Benzene is a colourless, mobile liquid with a char�  acteristic odour. An excellent solvent, it is also widely used as a starting  material for many plastics, dyes, detergents, insecticides, and other indus�  trial chemicals. Benzene is highly toxic, and long exposure may cause  LEUKEMIA.</p><p>Benzer, Seymour (b. Oct. 15, 1921, New York, N.Y., U.S.) U.S.  molecular biologist. He received his Ph.D. from Purdue University.

He was skilled in designing tapestries, accessories, furniture,  costumes, and elaborate stage settings for operas and extravagant theat�  rical productions; these were typically filled with fantastic iconography.  He satisfied the king�s appetite for splendour and inspired other cabinet�  makers such as Andre-Charles Boulle.</p><p>Berar \ba-'rar\ Historical region, west-central India. Located in what is  now northern Maharashtra state, Berar emerged as a distinct political  entity after the incursions of Muslim armies in the 13th century ad. It  formed part of several Muslim kingdoms until, on the breakup of the  Mughal Empire, it fell to the ruler of Hyderabad. Coming under British  control in 1853, it was subsequently assigned to various provinces; it has  been part of Maharashtra state since 1960. The region includes a rich  cotton-growing area in the Purna River basin.</p><p>Berber Any member of a community native to the Maghrib who speaks  one of various Berber languages, including Tamazight, Tashahit, and Tari-  fit. Berber-speakers were the original inhabitants of North Africa, though  many regions succumbed to colonization by the Roman Republic and Empire  and later (from the 7th century ad) to conquest by the Arabs. Berbers  gradually accepted Islam, and many switched to Arabic or became bilin�  gual. Berber languages are still spoken in some rural and mountain areas  of Morocco and Algeria and by some inhabitants of Tunisia and Libya.  Since the 1990s Berber intellectuals have sought to revive interest in the  language. The Berber-speaking Almoravid and Almohad dynasties built  empires in North Africa and Spain in the 11th�13th centuries.

He was opposed by numerous theo�  logians, most notably Lanfranc, and may have been excommunicated  (1050) by Pope Leo IX. He was condemned by the Council of Vercelli  (1050) and the Synod at Paris (1051).

Located on the Rhine  River, the area now lies in the districts of DOsseldorf and Cologne, Ger�  many. In the 11th century the counts of Berg acquired Westphalian lands  east of Cologne; these were incorporated into a duchy in 1380. Berg  became a leading iron and textile manufacturing centre in the 17th�18th  centuries. In 1806 Napoleon made it a grand duchy in his Confederation  of the Rhine. Following the Congress of Vienna in 1814�15, it became part  of Prussia.</p><p>Berg \'berk\, Alban (Maria Johannes) (b. Feb. 9, 1885, Vienna,  Austria-Hungary�d.

This would prove to be the decisive event in his life, and Schoen�  berg would remain his teacher for eight years. Under his influence, Berg�s  early late-Romantic tonal works gave way to increasing atonality and  finally (1925) to 12-tone composition. His Expressionist opera Wozzeck  (1922) would become the most universally acclaimed post-Romantic  opera. His second opera, Lulu, on which he worked for six years, remained  unfinished at his death. Berg�s other works include two string quartets,  including the Lyric Suite (1926); Three Pieces for Orchestra (1915); and  a violin concerto (1935).</p><p>Berg, Paul (b. June 30, 1926, New York, N.Y., U.S.) U.S. biochemist.  He received his Ph.D. from Western Reserve University. While studying  the actions of isolated genes, he devised methods for splitting DNA mol�  ecules at selected sites and attaching the resulting segments to the DNA  of a virus or plasmid, which could then enter bacterial or animal cells.  The foreign DNA was incorporated into the host and caused the synthe�  sis of proteins not ordinarily found there. One of the earliest practical  results of this research was the development of a strain of bacteria that  contained the gene for producing insulin. In 1980 Berg shared a Nobel  Prize with Walter Gilbert (b. 1932) and Frederick Sanger.</p><p>bergamot Vbor-go-.matN Any of several North American perennial  plants of the mint family, also known as bee balm, fragrant balm, and Indi�  an�s plume.

In the 14th century, German Hanseatic League merchants acquired  control over its trade; their influence in a weakened Norway lasted into  the 16th century. Repeatedly destroyed by fire (most notably in 1702 and  1916), Bergen has been resurrected each time. Its economy is based  largely on fishing and shipbuilding.

With  Eugene V. Debs he founded the Social Democratic Party, which became the  Socialist Party in 1901. He served in the U.S. House of Representatives  (1911-13) as the first Socialist ever elected to Congress. Elected again in  1918, he was denied his seat after being convicted under the Espionage  Act for opposing U.S. participation in World War I.

Its  name is from the Sinhalese word for �extreme weakness.� Symptoms  include fatigue, digestive problems, and limb numbness and weakness.  Dry beriberi involves gradual long-nerve degeneration, with muscle atro�  phy and loss of reflexes. Wet beriberi is more acute, with edema from car�  diac failure and poor circulation. Thiamin occurs widely in food but is  lost in processing; a well-balanced diet high in unprocessed foods can  prevent beriberi. In Western countries, chronic alcoholism is the most  common cause.</p><p>Bering, Vitus (Jonassen) (b. 1681, Horsens, Den.�d.

He joined the fleet of the Russian tsar Peter I and in 1724 was  appointed leader of an expedition to determine whether Asia and North  America were connected by land. In 1728 he set sail from the Kamchatka  Peninsula of Siberia and passed through what would later be named the  Bering Strait. His plan for a second expedition was expanded into Rus�  sia�s Great Northern Expedition (1733�43), which mapped much of the  Arctic coast of Siberia. After exploring the Alaskan coast, he fell ill from  scurvy and died after his ship was wrecked. His exploration paved the  way for a Russian foothold in North America.</p><p>Bering Sea Marginal sea, North Pacific Ocean. Enclosed by Alaska, the  Aleutian Islands, the Kamchatka Peninsula, and eastern Siberia, it covers  some 890,000 sq mi (2,304,000 sq km). It has numerous islands, includ�  ing Karagin and Nunivak, as well as the St. Lawrence, Aleutian, and  Komandor archipelagos. It is crossed diagonally by the International Date  Line. The sea is connected to the Arctic Ocean by the Bering Strait, which  separates Asia from North America and is believed to have been a land  bridge during the Ice Age that enabled migration from Asia to North  America. Vitus Bering�s exploration of the sea and strait in 1728 and 1741  formed a basis for Russian claims to Alaska.</p><p>Bering Sea Dispute Dispute between the U.S. and Britain (and  Canada) over the international status of the Bering Sea. In an attempt to  control seal hunting off the Alaskan coast, the U.S. in 1881 claimed  authority over the Bering Sea and the right to seize sealing vessels. When  several Canadian ships were seized in the late 1880s, Britain protested the  U.S. claim. An agreement in 1891 permitted both countries to police the  area. In 1893 an international tribunal determined that the area was part  of the high seas and that no nation had jurisdiction over it.</p><p>Berio, Luciano (b. Oct. 24, 1925, Oneglia, Italy�d.

After choreographing over 20 Broad�  way musicals, he was summoned to Hollywood to direct dance numbers  for Whoopee (1930). His elaborate production numbers, innovative cam�  era techniques, and opulent sets in such films as Gold Diggers of 1933  and Footlight Parade (1933) revolutionized the musical and offered  escapist fare for moviegoers during the Great Depression. When rising  production costs made such extravaganzas unfeasible, he directed less  innovative but still popular films such as The Gang�s All Here (1943).</p><p>Berkeley \'bark-leV George known as Bishop Berkeley (b.</p><p>March 12, 1685, near Dysert Castle, near Thomastown?, County Kil�  kenny, Ire.�d. Jan. 14, 1753, Oxford, Eng.) Irish bishop, philosopher,  and social activist. He worked principally at Trinity College, Dublin (to  1713), and as bishop of Cloyne (1734-52). He is best known for his con�  tention that, for material objects, to be is to be perceived (�Esse est per-  cipi�). His religious calling may have prompted his qualification that, even  if no human perceives an object, God does, thereby ensuring the contin�  ued existence of the physical world when not perceived by any finite  being. With John Locke and David Hume, he was one of the founders of  modern empiricism. Unlike Locke, he did not believe that there exists any  material substance external to the mind, but rather that objects exist only  as collections of sensible ideas. His works include An Essay Towards a  New Theory of Vision (1709), Treatise Concerning the Principles of  Human Knowledge (1710), and Three Dialogues Between Hylas and  Philonous (1713). He spent part of his career in America, where he advo�  cated educating Native Americans and blacks.

A strong monarchist, he  was forced to retire to his Virginia plantation during the Commonwealth  period in England (1652-59). Reappointed in 1660, he faced crop failures  and Indian attacks on the frontier.

With the Norman Conquest the Thames valley�s strategic importance was  recognized, and the first Windsor Castle was built. Windsor and Eton, on  Berkshire�s eastern boundary, contain the county�s most noted structures.

The wooded  hills are a continuation of the Green Mtns. of Vermont; they include the  Hoosac and Taconic ranges. Crossed by the Appalachian National Scenic  Trail, the Berkshires contain state parks and forests and are the home of  the Tanglewood summer music festival (in Lenox).</p><p>Berlage Vber-lak-oV, Hendrik Petrus (b. Feb. 21, 1856, Amsterdam,  Neth.�d. Aug. 12, 1934, The Hague) Dutch architect. After studies in  Zurich, he began his practice in Amsterdam (1889). His best-known work  is the Amsterdam Stock Exchange (1897-1903), notable for its forthright  use of structural steel and traditional Dutch brickwork. While visiting the  U.S. (1911), he was exposed to the work of Louis H. Sullivan and Frank  Lloyd Wright and later introduced their methods and ideas to Europe. His  work was characterized by the honest use of materials based on their fun�  damental properties and the avoidance of meaningless ornamentation.</p><p>Berle VbsrlV, Milton orig. Milton Berlinger (b. July 12, 1908, New  York, N.Y., U.S.�d. March 27, 2002, Los Angeles, Calif.) U.S. come�  dian. He appeared in vaudeville from age 10 and later acted in more than  50 silent films. He worked chiefly as a nightclub comedian (1939-49)  while vainly seeking a radio audience. His slapstick routines and facial  contortions, however, were more suited to a visual medium, and between  1937 and 1968 he appeared in 19 movies. His greatest success came with</p><p>the television variety show Texaco Star Theater (1948-54), a show so  popular that many people are said to have bought television sets just to  watch �Uncle Miltie.�</p><p>Berlin City and state (pop., 2002 est: city, 3,388,000; metro, area,  4,101,000), capital of Germany. Founded in the early 13th century, it was  a member of the Hanseatic League in the 14th century. It became the resi�  dence of the Hohenzollerns and the capital of Brandenburg. It was suc�  cessively the capital of Prussia (from 1701), the German Empire (1871-  1918), the Weimar Republic (1919�32), and the Third Reich (1933^15). In  World War II much of the city was destroyed by Allied bombing. In 1945  it was divided into four occupation zones: U.S., British, French, and  Soviet. The three Western powers integrated their sectors into one eco�  nomic entity in 1948; the Soviets responded with the Berlin blockade. When  independent governments were established in eastern and western Ger�  many in 1949, East Berlin was made the capital of East Germany, and  West Berlin, though surrounded by East Germany, became part of West  Germany. Continuing immigration from East to West Berlin through the  1950s prompted the 1961 erection of the Berlin Wall. The area immedi�  ately became the most vivid focal point of the Cold War. The dramatic  dismantling of the wall in 1989 marked the international upheaval that  accompanied the end of the Soviet Union. Berlin became reunified as  Germany�s official capital in 1991; the transfer of government from Bonn  was completed in 1999. It is the site of the University of Berlin, Charlot-  tenburg Palace, Brandenburg Gate, and Berlin Zoo and is home to the  Berlin Opera and Berlin Philharmonic Orchestra.</p><p>Berlin, Congress of (June 13-July 13, 1878) Diplomatic meeting of  the major European powers at which the Treaty of Berlin replaced the  Treaty of San Stefano. Dominated by Otto von Bismarck, the congress  solved an international crisis by revising the peace settlement to satisfy  the interests of Britain and Austria-Hungary. By humiliating Russia and  failing to acknowledge adequately the aspirations of the Balkan peoples,  it laid the foundation for future Balkan crises.</p><p>Berlin, Irving orig. Israel Baline (b. May 11, 1888, Mogilyov,  Russia�d. Sept. 22, 1989, New York, N.Y., U.S.) U.S. songwriter. The  son of a Russian Jewish cantor, he and his family immigrated to New  York City in 1893. He worked as a street singer and singing waiter, then  began writing songs. His first published song, �Marie from Sunny Italy,�  appeared in 1907; a printer�s error named him Irving Berlin. In 1911 he  wrote the great hit of Tin Pan Alley�s ragtime vogue, �Alexander�s Ragtime  Band.� He may have written more than 1,500 songs. Some of his songs  include �Cheek to Cheek� and �God Bless America.� He scored many  successful films; his score for Holiday Inn (1942) introduced �White  Christmas,� one of the best-selling songs of all time. Altogether Berlin  wrote the scores for 19 Broadway shows (including Annie Get Your Gun,  1946) and 18 films.</p><p>Berlin, Sir Isaiah (b. June 9, 1909, Riga, Latvia�d. Nov. 5, 1997,  Oxford, Eng.) Latvian-born British political philosopher and historian of  ideas. His family immigrated to Britain in 1920. Educated at the Univer�  sity of Oxford, Berlin taught there from 1950 to 1967, serving as presi�  dent of Wolfson College from 1966 to 1975 and thereafter teaching at All  Souls College. His writings on political philosophy are chiefly concerned  with the problem of free will in increasingly totalitarian and mechanistic  societies. His most important works include Karl Marx (1939), The  Hedgehog and the Fox (1953), Historical Inevitability (1955), The Age  of Enlightenment (1956), and Four Essays on Liberty (1969).</p><p>Berlin, University of or Humboldt University of Berlin Pub�  lic university in Berlin, Germany. It was founded (as Friedrich Wilhelm  University) in 1809-10 by Wilhelm, baron von Humboldt. By the mid 1800s  it had attained world renown for its modern curriculum and its scientific  research institutes. Among its faculty were G.W.F. Hegel, Johann Gott�  lieb Fichte, Arthur Schopenhauer, Leopold von Ranke, Hermann von Helm�  holtz, Friedrich Schleiermacher, and Jacob and Wilhelm Grimm. In the 1930s  it was Nazified, and many of its faculty fled abroad. Under the German  Democratic Republic after World War II, it was renamed Humboldt Uni�  versity and given a Marxist-Leninist orientation. It was reorganized after  East and West Germany reunified in 1990.</p><p>Berlin blockade and airlift (1948^-9) International crises that arose  from an attempt by the Soviet Union to force the Allied powers (U.S.,  Britain, and France) to abandon their postwar jurisdictions in West Ber�  lin.

An Allied embargo on exports from the Eastern bloc forced the  Soviets to lift the blockade after 11 months.</p><p>Berlin Painter (fl. 500^160 bc, Athens, Greece) Greek vase painter,  the outstanding vase painter of the late Archaic period. He is best known  as the decorator of an amphora now in Berlin. Whereas it had been cus�  tomary to frame the groups of figures on each side of the vase with pat�  tern bands, the Berlin Painter eliminated the frame, allowing the figures  to dominate and stand out sharply against the black background. Nearly  300 vases are attributed to him.</p><p>Berlin Wall Barrier surrounding West Berlin that closed off East Ger�  mans access to West Berlin from 1961 to 1989 and served as a symbol  of the Cold War�s division of East and West Germany. The barrier was  built in response to the flight of about 2.5 million East Germans to West  Germany in the years 1949-61. First erected on the night of Aug. 12-13,  1961, it developed into a system of concrete walls topped with barbed  wire and guarded with watchtowers, gun emplacements, and mines. It was  opened in the 1989 democratization that swept through eastern Europe  and has been largely torn down.</p><p>Berlin West Africa Conference (1884-85) Series of negotiations at  Berlin in which the major European nations met to determine the future  of Central Africa.

Born into a  middle-class Sardinian family, he joined the Communist Party in 1943  and held a series of party posts before becoming secretary-general in  1972, a post he would keep until his death. He became a leading advo�  cate of �national communism,� seeking independence from Moscow and  favouring the adaptation of Marxism to local requirements. His proposal  for a coalition government of Christian Democrats and communists was  never realized.</p><p>Berlioz Vber-le-.ozX, (Louis-) Hector (b. Dec. 11, 1803, La Cote-  Saint-Andre, France�d. March 8, 1869, Paris) French composer. He stud�  ied guitar in his early years and later studied music at the Paris  Conservatoire, against his parents� wishes. His first great score was the  stormy Symphonie fantastique (1830), which became a landmark of the  Romantic era. Impulsive and passionate, he was a contentious critic and  gadfly constantly at war with the musical establishment. Though he was  the most compelling French musical figure of his time, his idiosyncratic  compositional style kept almost all his music out of the repertory until the  mid-20th century. His works include the operas Benvenuto Cellini (1837)  and Les Troyens (1858); the program symphonies Harold in Italy (1834)  and Romeo and Juliet (1839); and the choral dramas La Damnation de  Faust (1846) and L�Enfance du Christ (1854). He was also known as a  brilliant conductor with an unsurpassed knowledge of the orchestra; his  orchestration treatise (1843) is the most influential such work ever writ�  ten.</p><p>Berlusconi, Silvio (b. Sept. 29, 1936, Milan, Italy) Italian media  tycoon and prime minister in 1994 and again from 2001. After graduat�  ing from the University of Milan, he became a real estate developer,  amassing a considerable fortune by the 1970s. By the 1990s he owned  more than 150 businesses, including three television networks and Italy�s  largest publishing house. In 1994 he founded Forza Italia, a conservative  political party, and was elected prime minister. Faced with conflict of  interest and other charges, he resigned in December 1994. He was later  convicted of fraud and corruption, though he was acquitted of tax eva�  sion. Despite the convictions and criticism of his control of much of the  Italian media, he remained the leader of Forza Italia and again became  prime minister in 2001.</p><p>Bermejo \ber-'ma-ho\, Bartolome or Bartolome de Cardenas</p><p>Vkar-da-nas\ (b. c. 1440, Cordoba, Spain�d. 1495, Barcelona) Spanish  painter.

Comprising 7 main islands and about 170 additional  (named) islets and rocks, it lies about 570 mi (920 km) southeast of Cape  Hatteras, N.C., U.S. The archipelago has a total land area of about 20.5  sq mi (53 sq km). The capital is Hamilton on Main Island. Bermuda was  named for Juan de Bermudez, who may have visited the islands in 1503.  Colonized by the English in 1612, Bermuda became a crown colony in  1684, and its status changed to an overseas territory in 2002.

Lying along a loop of the Aare River, it was founded as a  military post in 1191 by Berthold V, duke of Zahringen. It became a free  imperial city in 1218. Gradually extending its power, it became an inde�  pendent state, and in 1353 it entered the Swiss Confederation. It was a  scene of disputation in 1528 between Roman Catholics and reformers,  which led to its subsequent championing of Protestant doctrines. It  became a member of the Helvetic Republic and in 1848 was made the  capital of Switzerland. It is headquarters of the international postal, rail�  way, and copyright unions.</p><p>Bern Convention officially International Convention for the  Protection of Literary and Artistic Works International agree�  ment adopted in Bern, Switz., in 1886 to protect copyrights on an inter�  national basis.

He discovered the  role of the pancreas in digestion, the glycogenic function of the liver in  carbohydrate metabolism, and blood-supply regulation by the vasomotor  nerves. He helped establish the principles of experimentation in the life  sciences, including the need for a hypothesis. His concept of the internal  environment of the organism led to the present understanding of homeo�  stasis. Bernard also studied the effects of such poisons as carbon monox�  ide and curare.

Born into an aristocratic family  near Dijon, he turned away from a literary education for the monastic life,  entering the austere religious community at Citeaux in 1112. As abbot of  the Cistercian monastery at Clairvaux, Champagne, which he founded in  1115, he helped establish the widespread popularity of the order. Between  1130 and 1145 he mediated civil and ecclesiastical councils and theologi�  cal debates, and his support for Pope Innocent II helped secure the papacy  during the schism with Anacletus. Bernard was the confidant of five popes  and became perhaps the most renowned religious figure in Europe. He  actively preached the Second Crusade and wrote a number of sermons on  the Song of Solomon.

Dec. 7, 1598, Naples, Kingdom of  Naples�d. Nov. 28, 1680, Rome, Papal States) Italian architect and art�  ist credited with creating the Baroque style of sculpture. He began his  career working for his father, a sculptor. Among his early sculptures are  Apollo and Daphne (1622-24) and an active David (1623-24). Under the  patronage of Urban VIII, the first of eight popes he was to serve, he cre�  ated the baldachin over the tomb of St. Peter in Rome. Bernini�s architec�  tural duties increased after 1629, when he was appointed architect of St.  Peter's Basilica and the Palazzo Barberini. His works often represent a  fusion of architecture and sculpture, as in the Comaro Chapel, in Santa  Maria della Vittoria, Rome, with its celebrated theatrical sculpture, The  Ecstasy of St. Teresa (1645-52).

A consequence is that, for horizontal flow, as the speed of a fluid increases,  the pressure it exerts decreases. Derived by Daniel Bernoulli (see Ber�  noulli family), the principle explains the lift of an airplane in motion. As  the speed of the plane increases, air flows faster over the curved top of  the wing than underneath. The upward pressure exerted by the air under  the wing is thus greater than the pressure exerted downward above the  wing, resulting in a net upward force, or lift. Race cars use the principle  to keep their wheels pressed to the ground as they accelerate.

In London he met Friedrich Engels and was  influenced by the Fabian Society. Returning to Germany in 1901, Bern�  stein became the political theorist of the revisionists and was one of the  first socialists to modify such Marxist tenets as the imminent collapse of  capitalism.

In 1944 he triumphed with his  music for Jerome Robbins�s ballet  Fancy Free and the Broadway show  On the Town. As a composer he  made use of diverse elements ranging from biblical themes to jazz  rhythms. His best-known composition was the score for the hit musical  West Side Story (1957); other works include the musicals Wonderful Town  (1952) and Candide (1956), three symphonies, the Chichester Psalms  (1965), and the theatrical Mass (1971).

He was named the Ameri�  can League�s Most Valuable Player in 1951, 1954, and 1955. He caught  in more World Series games (75) than any other catcher and hit 20 or  more home runs a season through 1958. He managed the Yankees in 1964  but was fired and became a coach and manager (1965-75) with the New  York Mets. He returned to the Yankees as a coach (1976-82) and later  manager (1983-85). He was known for idiosyncratic remarks such as �It  ain�t over till it�s over� and �It�s deja vu all over again.� The American  cartoon character Yogi Bear was named for him.</p><p>Berrigan, Daniel (Joseph) and Philip (Francis) (respectively b.

After joining the Catholic priesthood (Daniel became a Jesuit, Philip  a Josephite), the brothers became involved in nonviolent political activ�  ism, carrying out campaigns of civil disobedience to oppose racism, the  nuclear arms race, and the Vietnam War. They were best known for their  Vietnam-era raid of draft-board files in Catonsville, Md., which they  destroyed with chicken blood and napalm. They were also known for the  persistence of their activism. Philip later left the priesthood. Both authored  numerous books on their work and beliefs; Daniel also wrote poetry and  plays.</p><p>Berruguete, Alonso (b. c. 1488, Paredes de Nava, Castile�d. 1561,  Toledo, Castile) Spanish sculptor and painter. His father, Pedro Berruguete,  was a great Renaissance painter. Alonso worked in Florence and Rome  c. 1508-16. In 1516 he returned to Spain, and in 1518 he became court  painter to Charles V. He succeeded primarily as a sculptor, however, and  became known for his intensely emotional Mannerist sculptures of figures  portrayed in spiritual torment or in transports of religious ecstasy. His  best-known work is a set of wooden reliefs with highly expressive fig�  ures for choir stalls in Toledo Cathedral (1539-43). Berruguete�s use of  a rather rich and extravagant but delicate ornamentation in his church  decorations is typical of Spain�s Plateresque style.

After a sojourn in Italy, he  returned to Spain, where he painted numerous altarpieces and also worked  as a fresco painter in Toledo Cathedral (1483-99). The influence of Flem�  ish and Italian art is evident in his panel paintings, which are character�  ized by luxurious ornament and gold decoration. He was the first great  Renaissance painter in Spain. His son Alonso Berruguete was a sculptor  and painter.</p><p>Berry \be-'re\ Historical region and former province, central France. It  was originally inhabited by the Bituriges Cubi, who opposed Vercinge-  torix. Under Roman rule it was part of Aquitania Prima. A countship in  the Carolingian period, it fell to the French crown in the 12th century.  When Aquitaine was acquired by Henry II of England, Berry became a  matter of dispute between England and France. As a duchy, at one time  it came under Jean de France, duke de Berry, an important patron of the  arts. It returned to France in 1601 and remained a province until 1790.</p><p>berry Simple, fleshy fruit that usually has many seeds (e.g., the banana,  tomato, or cranberry).

He did research in alcohols and carboxylic acids, the syn�  thesis of hydrocarbons, and reaction rates, studied the mechanism of  explosion, discovered many coal-tar derivatives, and wrote on the history  of early chemistry. He was a pioneer in the use of chemical analysis as a  tool of archaeology. His work helped break down the traditional division  between organic and inorganic compounds. He opposed the then-current  idea that a �vital force� is responsible for synthesis and was one of the  first to prove that all chemical phenomena depend on physical forces that  can be measured.</p><p>Berthoud \ber-'tu\, Ferdinand (b.

An ancient town of Judaea, it was the early  home of King David. A Roman garrison was stationed there during the  Second Jewish Revolt (ad 135). Christians regard it as the birthplace of  Jesus, and in the early 4th century the Church of the Nativity, located on  what is believed to be the site of Jesus� birth, was built there. Bethlehem  was included in the British mandate of Palestine (1923-48); in 1950, fol�  lowing the first Arab-Israeli war (1948-49), it was annexed by Jordan.  After the Six-Day War (1967), it became part of the West Bank territory  under Israeli administration. Under an agreement reached in 1995, Israel  ceded rule of the town to a Palestinian Authority. Long an important pil�  grim and tourist centre, it is also an agricultural market closely linked to  Jerusalem.</p><p>Bethlehem City (pop., 2000: metro area, 71,329), eastern Pennsylva�  nia, U.S. With Allentown and Easton it forms an urban industrial com�  plex. Founded in 1741 by Moravian missionaries, it was the site of a  hospital for Continental soldiers during the American Revolution. Indus�  trialization began with the opening of the Lehigh Canal (1829) and the  founding of the forerunner of the Bethlehem Steel Corp. (1857); the city  became a major steel-producing centre. Its economy has since diversified  to include textiles, metal products, furniture, and chemicals.</p><p>Bethlehem Steel Corp. U.S. corporation created in 1904 to consoli�  date Bethlehem Steel Co., the Union Iron Works, and a few smaller com�  panies. Its principal founder was  Charles M. Schwab. In its early  decades Bethlehem Steel (based in  Bethlehem, Pa.) produced primarily  coal, iron ore, and steel; it supplied  the steel for the Golden Gate Bridge.</p><p>In later decades it diversified into  plastics, chemicals, and nonferrous  ores. By the late 20th century it had  become one of the largest steel pro�  ducers in the U.S., with operations in  Pennsylvania, Indiana, Maryland,  and New York. The company�s high  labour costs, aging infrastructure,  and inability to compete globally led  to its liquidation in 2003.</p><p>Bethmann Hollweg Vbat-.man-  h6l-,vek\, Theobald von (b. Nov.

By keeping the vows,  including inexhaustible service to all buddhas and the embracing of all  universes, the faithful can realize the universe of interdependent phenom�  ena manifested in the Buddha and enter into the Pure Land of Amitabha.</p><p>Bhagavadgita Vba-go-.vad-'ge-toV (Sanskrit: �Song of God�) One of  the greatest of the Hindu scriptures, constituting part of the Mahabharata.  It is written in the form of a dialogue between the warrior Prince Arjuna  and the charioteer Krishna, an incarnation of Vishnu. It was probably com�  posed in the 1st or 2nd century ad, later than much of the epic. Concerned  over the suffering the impending battle will cause, Arjuna hesitates, but  Krishna explains that the higher way is the dispassionate discharge of duty  without concern for personal triumph. The Bhagavadgita considers the  nature of God and ultimate reality and offers three disciplines for tran�  scending the limitations of this world: jnana (knowledge or wisdom),  karma (dispassionate action), and bhakti (love of God). It has inspired  numerous commentaries over the centuries, including those by Ramanuja  and Mohandas K. Gandhi.</p><p>Bhagavata Vba-go-.vo-toV Member of the earliest recorded Hindu sect,  representing the beginnings of theistic, devotional worship and modem  Vaishnavism. The Bhagavata sect originated in the Mathura region c. 3rd-  2nd century bc and spread through western, northern, and southern India.  The faith centers on devotion to a personal god, variously called Vishnu,  Krishna, Hari, or Narayana. The Bhagavadgita (lst-2nd century ad) is the</p><p>earliest exposition of the Bhagavata system, but its central scripture is the  Bhagavata Purana. The sect was prominent within Vaishnavism until the  11th century, when bhakti (devotional worship) was revitalized by  Ramanuja.</p><p>bhakti \'bok-te\ Southern Asian devotional movement, particularly in  Hinduism, emphasizing the love of a devotee for his or her personal god.  In contrast to Advaita, bhakti assumes a dualistic relationship between  devotee and deity. Though Vishnu, Shiva, and Shakti (see shakti) all have  cults, bhakti characteristically developed around Vishnu�s incarnations as  Rama and Krishna. Practices include reciting the god�s name, singing  hymns, wearing his emblem, and making pilgrimages. The fervour of  South Indian hymnists in the 7th-10th centuries spread bhakti and  inspired much poetry and art. Poets such as Mirabai conceived of the rela�  tionship between the worshiper and the god in familiar human terms (e.g.,  the lover and beloved), while more abstract poets such as Kabir and his  disciple Nanak, the first Sikh Guru and founder of Sikhism, portrayed the  divinity as singular and ineffable.</p><p>bharata natya Vba-ro-to-'nat-yoX Principal classical dance style of  India, indigenous to Tamil Nadu and prevalent in South India. It expresses  Hindu religious themes, and its techniques and terminology are found in  the treatise Natya-shastra , written by the sage Bharata (3rd century ad).  One dancer performs the entire two-hour program, accompanied by  drums, drone, and singer. Originally performed only by female temple  dancers, the art fell into disrepute as temple dancing became associated  with prostitution, but it was revived in its original purity in the late 19th  century. It was not brought to the stage until the 1930s.</p><p>Bharatiya Janata Party (BJP) English Indian People's Party</p><p>Pro-Hindu political party of India. The BJP traces its roots to the the  Bharatiya Jana Sangh (founded in 1951), which advocated the rebuilding  of India in accordance with Hindu culture. The BJP was formally estab�  lished in 1980. It achieved its first significant electoral success in 1989,  though in 1992 the destruction of the Babri Mosjid (Mosque of Babur)  in Ayodhya caused a backlash against it. In 1996 the BJP formed a short�  lived government. Two years later the party and its allies formed a major�  ity government with Atal Bihari Vajpayee as prime minister. Vajpayee again  became prime minister in 1998 as head of a coalition of the BJP and other  parties. In 2004, however, the coalition was defeated in parliamentary  elections, and Vajpayee resigned from office.</p><p>Bharatpur Vbo-rot-.piuA or Bhurtpore Vbort-.porX City (pop., 2001  prelim.: 204,456), Rajasthan state, northwestern India. Located west of  Agra, it was founded c. 1733 and was the capital of the princely state of  Bharatpur. It was so strongly fortified that it successfully resisted the Brit�  ish siege in 1805, and it was not taken by them until 1826. The city is  renowned for the superb bird sanctuary at nearby Keoladeo National Park.</p><p>Bharhut \'ba-rot\ sculpture Indian sculpture from the mid 2nd cen�  tury bc that decorated the great stupa, or relic mound, of Bharhut, in  Madhya Pradesh, India. It is now mostly destroyed; the railings and gate�  ways that remain are in Kolkata�s (Calcutta�s) Indian Museum. The orna�  mental medallions depicting legends of the Buddha�s previous births and  events in his life are labeled and so are indispensable for an understand�  ing of Buddhist iconography. The Bharhut style marked the beginning of  a tradition of Buddhist narrative relief and decoration of sacred buildings  that continued for several centuries.</p><p>Bhartrhari \'ba-tr9-re\ (b. 570?, Ujjain, Malwa, India�d. 651?, Ujjain)  Indian Hindu philosopher, poet, and grammarian. He was of noble birth;  according to legend, he made seven attempts to renounce the world for  monastic life before eventually becoming a yogi and moving into a cave  near Ujjain. Vakyapadiya is his major work on the philosophy of language.  Also ascribed to him are three collections of poetry, each containing 100  verses: Shrngara-shataka (on love), Niti-shataka (on ethics and polity),  and Vairagya-shataka (on dispassion). His poem Bhatti kavya demon�  strates the subtleties of Sanskrit.</p><p>Bhasa Vba-S9\ (b. 3rd century ad) Indian dramatist. The earliest known  dramatist in Sanskrit, he was known only by the allusions of other San�  skrit dramatists until the texts of 13 of his dramas were discovered and  published in 1912. Most of his works are adaptations of themes of hero�  ism and romantic love borrowed from two epics, the Ramayana and the  Mahabharata. He diverged from the conventions of the time by portray�  ing battles and killings on the stage. His influence is seen in the works of  the 5th-century dramatist Kalidasa.</p><p>TIIE TAWNY OWL*</p></section><section><p>(o)uo5 b&gt;otx inr owi, on howi.ii.</p><p>{Strix StridmU, Linn.�A- CJmt-Jmamt, Bui!.</p><p>The Tawny Owl, wood engraving by  Thomas Bewick, from his History of  British Birds, 1797 - 1804 .</p><p>COURTESY OF THE TRUSTEES OF THE BRITISH MUSEUM;  PHOTOGRAPH, J.R.

He was the lineal successor  of Brahmagupta as head of an astronomical observatory at Ujjain, the  leading mathematical centre of ancient India. His mathematical works  were the first to make full and systematic use of the decimal system. He  evidently was the first to gain some understanding of the meaning of divi�  sion by zero. He used letters to represent unknown quantities, much as in  modern algebra, and solved indeterminate equations of 1st and 2nd  degrees. He wrote on his astronomical observations of planetary positions,  conjunctions, eclipses, cosmography, geography, and the mathematical  techniques and astronomical equipment used in these studies.

Today children may enter monastic life as novices, but candi�  dates for ordination must be 21 years old. There are some 200 rules; sexual  relations, taking of life, stealing, or boasting of spiritual attainment will  lead to expulsion. A bhiksu shaves his head and face, owns a few essen�  tial items, and begs daily for his food. Theravada Buddhism forbids monks  to handle money and perform labour.

Area: 14,824 sq mi (38,394 sq km). Population  (2005 est.): 776,000. Capital: Thimphu. There are three main ethnic groups:</p><p>Nepalese in the southwest. Languages:</p><p>Dzongkha (official), Tibetan dialects. Religions: Mahayana Buddhism  (official); also Hinduism. Currency: ngultrum. The northern part of the  country lies in the Great Himalayas, with peaks surpassing 24,000 ft  (7,300 m) and high valleys lying at 12,000-18,000 ft (3,700-5,500 m).  Spurs radiate southward, forming the Lesser Himalayan ranges. Several  fertile valleys there, at elevations of 5,000-9,000 ft (1,500-2,700 m), are  fairly well populated and cultivated. South of these mountains lies the  Duars Plain, controlling access to the strategic mountain passes; much of  it is hot and steamy and covered with dense forest. The Bhutanese  economy is mainly agricultural; nearly all exports go to India. Bhutan is  a monarchy with one legislative house; the head of state is the monarch,  and the head of government is the prime minister. Bhutan�s mountains  and forests long made it inaccessible to the outside world, and its feudal  rulers banned foreigners until well into the 20th century. It nevertheless  became the object of foreign invasions; in 1865 it came under British  influence, and in 1910 it agreed to be guided by Britain in its foreign  affairs. It later became oriented toward British-ruled India, though much  of its trade continued to be with Tibet. India took over Britain�s role in  1949, and the Chinese army�s presence in neighbouring Tibet since 1950  further strengthened Bhutan�s ties with India. The apparent Chinese threat  made its rulers aware of the need to modernize, and it has embarked on  a program to build roads and hospitals and to create a system of secular  education.</p><p>Bhutto Vbu-to\, Benazir (b. June 21, 1953, Karachi, Pak.) Pakistani  politician, the first woman leader of a Muslim nation in modem history.  After receiving an education at Harvard and Oxford, she led the political  opposition to Pres. Zia-ul-Haq after the execution of her father, Zulfikar  An Bhutto in 1979. She subsequently endured frequent house arrest (1979-  84) and was exiled (1984-86). When Zia died in a plane crash in 1988,  she became prime minister of a coalition government. She was unable to  do much to combat Pakistan�s widespread poverty, governmental corrup�  tion, and increasing crime, and her government was dismissed in 1990 on  charges of corruption and other malfeasance. A second stint as prime  minister (1993-96) ended similarly. In 1999 she was convicted of taking  kickbacks from a Swiss company and sentenced in absentia to five years  in prison.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>214 I Bhutto &#x25BA; biblical translation</p><p>Bhutto, Zulfikar Ali (b. Jan. 5, 1928, near Larkana, Sindh, India�d.  April 4, 1979, Rawalpindi, Pak.) President (1971-73) and prime minister  (1973-77) of Pakistan. Son of a prominent politician, he was educated in  India, the U.S., and Britain. He served eight years in the government of  Mohammad Ayub Khan (1907-74) then resigned to form the Pakistan  People�s Party (1967). After the overthrow of the Ayub Khan regime and  the Pakistani civil war, Bhutto became president (1971). He nationalized  several key industries and taxed landed families. He became prime min�  ister in 1973, and his government, retaining martial law, began a process  of Islamization. Bhutto�s party won elections in 1977, but the opposition  accused him of electoral fraud. Gen. Zia-ul-Haq seized power and had  Bhutto imprisoned and later executed. Benazir Bhutto is his daughter.</p><p>Biafra \be-'af-r3\ Former secessionist state, West Africa. It constituted  the former Eastern Region of Nigeria, inhabited principally by the Igbo.  In a period of political and economic instability in the 1960s, the resent�  ment of the Hausa in the north toward the more prosperous and educated  Igbo exploded in fighting and massacres, which led to the secession of  the Eastern Region as the state of Biafra in 1967. A costly civil war and  the death by starvation of an estimated one million civilians ended in  Biafra�s collapse and reincorporation into Nigeria in 1970.</p><p>Biafra, Bight of Inlet of the Atlantic Ocean, West Africa.

The Jewish scriptures  consist of the Torah (or Pentateuch), the Neviim (�Prophets�), and the  Ketuvim (�Writings�), which together constitute what Christians call the  Old Testament. The Pentateuch and Joshua relate how Israel became a  nation and came to possess the Promised Land. The Prophets describe the  establishment and development of the monarchy and relate the prophets�  messages. The Writings include poetry, speculation on good and evil, and  history. The Roman Catholic and Eastern Orthodox Bible includes addi�  tional Jewish writings called the Apocrypha. The New Testament consists  of early Christian literature. The Gospels tell of the life, person, and teach�  ings of Jesus. The Acts of the Apostles relates the earliest history of  Christianity. The Epistles (Letters) are correspondence of early church  leaders (chiefly St. Paul) and address the needs of early congregations.  Revelation is the only canonical representative of a large genre of early  Christian apocalyptic literature. See also biblical source, biblical translation.

The first three (synoptic) Gospels have a  common source, Matthew and Luke being based on Mark and a lost source  called Q; John conveys an independent tradition. Biblical sources are  studied to uncover the history of the scriptures and to restore texts as  closely as possible to their original content. Scholars may also analyze  biblical sources in an effort to reconstruct the oral tradition behind them.</p><p>biblical translation Art and practice of translating the Bible. The Old  Testament was originally written in Hebrew, with scattered passages of  Aramaic. It was first translated in its entirety into Aramaic and then, in  the 3rd century ad, into Greek (the Septuagint). Hebrew scholars created  the authoritative Masoretic text (6th-10th century) from Aramaic Targums,  the original Hebrew scrolls having been lost. The New Testament was  originally in Greek or Aramaic. Christians translated both Testaments into  Coptic, Ethiopian, Gothic, and Latin. St. Jerome�s Latin Vulgate (405) was  the standard Christian translation for 1,000 years. New learning in the  15th�16th century generated new translations. Martin Luther translated the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>bibliography &#x25BA; Biddle I 215</p><p>entire Bible into German (1522-34). The first complete English transla�  tion, credited to John Wycliffe, appeared in 1382, but it was the King  James version (1611) that became the standard for more than three cen�  turies. By the late 20th century the entire Bible had been translated into  250 languages and portions of it into more than 1,300.</p><p>bibliography Broadly, the systematic study and description of books.  The word can refer to the listing of books according to some system  (called descriptive, or enumerative, bibliography), to the study of books  as tangible objects (called critical, or analytical, bibliography), or to the  product of those activities. The purpose of bibliography is to organize  information about materials on a given subject so that students of the sub�  ject may have access to it. A descriptive bibliography may take the form  of information about a particular author�s works or about works on a given  subject or on a particular nation or period. Critical bibliography, which  emerged in the early 20th century, involves meticulous descriptions of the  physical features of books, including the paper, binding, printing, typog�  raphy, and production processes used, to help establish such facts as print�  ing dates and authenticity.</p><p>Bibliotheque Nationale de France V.bib-le-o-'tek-.na-se-o-'nal-  d3-'fra n s\ Most important library in France and one of the oldest in the  world. The nation�s first royal library, the Bibliotheque du Roi (�King�s  Library�), was established under Charles V (r. 1364-80) but later dis�  persed; another was established under Louis XI (r. 1461-83). From 1537  the library received a copy of every French publication. It was moved  from Fontainebleau to Paris in the late 16th century and opened to the  public in 1692. It acquired its current name in 1795, and its collection  was expanded through Revolutionary appropriations and Napoleon�s  acquisitions. In 1995 it moved to a new facility with a controversial  design; this facility now houses all its books (more than 12 million), peri�  odicals, and magazines.</p><p>bicameral system System of government in which the legislature  comprises two houses. It originated in Britain (see Parliament), where  eventually it served to represent the interests of both the common people  and the elite and to ensure deliberation over legislation. In the U.S. the  bicameral system is a compromise between the claims for equal repre�  sentation among the states (each state is represented by two members of  the Senate) and for equal representation among citizens (each member of  the House of Representatives represents roughly the same number of  people). Each house has powers not held by the other, and measures need  the approval of both houses to become law. Many contemporary federal  systems of government have bicameral legislatures. All U.S. states except  Nebraska have bicameral legislatures.

It is a weak base and dissociates into water and carbon  dioxide gas as it dissolves in the presence of hydrogen ions. In addition to  household uses as an antacid, cleaner, and deodorizer, it is used in manu�  facturing effervescent salts and beverages and baking powder. Industrial  uses include production of other sodium salts, treatment of wool and silk,  and use in pharmaceuticals, sponge rubber, fire extinguishers, cleaners,  lab reagents, mouthwash, and gold and platinum plating.</p><p>Bichat \be-'sha\, (Marie-Francois-) Xavier (b. Nov. 11/14, 1771,  Thoirette, Fra.�d. July 22, 1802, Lyon) French anatomist and physiolo�  gist. In addition to bedside observations of patients, he conducted autop�  sies to study the changes disease causes in various organs. With no  knowledge of the cell as the functional unit of living things, Bichat was  among the first to see the organs of the body as being formed through the  specialization of simple, functional units (tissues). Without using a micro�  scope, he distinguished 21 kinds of tissues that, in different combinations,  form the organs of the body. His systematic study of human tissues helped  create the science of histology.</p><p>bichon frise \be-,sho n -fre-'za\ Breed of small dog noted for its fluffy  coat and cheerful disposition.

It is the homeland of the Bicol, the country�s fifth largest ethnolinguistic  group, and it has been a stronghold of Philippine communists.</p><p>bicycle Lightweight, two-wheeled, steerable machine that is propelled  by the rider. The wheels are mounted in a metal frame, and the front wheel  is held in a movable fork. The rider sits on a saddle and steers with handle�  bars attached to the fork, propelling the bicycle with two pedals attached  to cranks that turn a chainwheel. An endless chain transmits power from  the chainwheel to a sprocket on the back wheel. A heavy, pedalless form  built in 1818 was propelled simply by the rider paddling his feet against  the ground. In the early 1840s Scottish blacksmith Kirkpatrick Macmillan  (1813-78) built bicycles propelled by pedals, cranks, and drive rods; he is  widely credited with having invented the bicycle. Important innovations  were introduced by Pierre and Ernest Michaux in France in the early  1860s, and by 1865 their company was manufacturing 400 velocipedes a  year. A lighter version produced in England in 1870 (nicknamed the  �penny-farthing�) featured a large front wheel and small back wheel. By  the 1890s the standard bicycle design was established, and, with the  smooth ride enabled by the new pneumatic tires, its popularity exploded.  The so-called mountain bike became the standard design by the early  1990s. The bicycle is used worldwide as a basic means of transportation.</p><p>Components of a modern touring bicycle.</p><p>� MERRIAM-WEBSTER INC.</p><p>Bidault \be-'do\, Georges (-Augustin) (b.

In  1644 he wrote Twelve Arguments Drawn Out of Scripture, denying the  deity of the Holy Spirit. When the manuscript reached church authorities, he  was arrested and imprisoned for two years. After its publication in 1647 he  was again detained, and copies of the book were burned. His later writings  attacked the doctrine of the Holy Trinity.

In 1823 Monroe appointed  him president of the Second Bank of  the United States. He developed the  bank into the first effective U.S. cen�  tral bank, sponsoring policies that  curbed credit, regulated the money  supply, and safeguarded government  deposits. In 1832 the bank came  under attack from Pres. Andrew Jack-  son, who managed to terminate its  national charter in 1836.

Reluctant to join the Bear Flag revolt of Americans  in California against Mexico, he nonetheless helped draw up the Bear Flag  Republic�s resolution of independence in July 1846. He fought under John  C. Fremont in the Mexican War and assisted in the recapture of Los Ange�  les in 1847. At the end of the war he returned to Sutter�s Fort, where he  was the first to find gold on the Feather River. Later he became a leading  agriculturalist and played a prominent role in state politics.

As a young man he traveled and sketched through�  out Europe before returning to the U.S. to join a westward-bound expe�  dition in 1859. Specializing in grandiose pictures of vast mountain  scenery, he achieved great popularity in his lifetime with panoramic and  often fanciful scenes of the American West, including The Rocky Moun�  tains (1863) and Mount Corcoran (c. 1875-77). His huge paintings were  actually executed in his New York City studio.</p><p>big bang Model of the origin of the universe, which holds that it  emerged from a state of extremely high temperature and density in an  explosive expansion 10 billion�15 billion years ago. Its two basic  assumptions�that Albert Einstein�s general theory of relativity correctly  describes the gravitational interaction of all matter and that an observer�s  view of the universe does not depend on direction of observation or on  location�make it possible to calculate physical conditions in the universe  back to a very early time called the Planck time (after Max Planck).  According to the model proposed by George Gamow in the 1940s, the  universe expanded rapidly from a highly compressed early state, with a  steady decrease in density and temperature. Within seconds, matter pre�  dominated over antimatter and certain nuclei formed. It took another mil�  lion years before atoms could form and electromagnetic radiation could  travel through space unimpeded. The abundances of hydrogen, helium,  and lithium and the discovery of cosmic background radiation support the  model, which also explains the redshifts of the light from distant galaxies  as resulting from the expansion of space.</p><p>Big Ben Clock housed in the tower at the eastern end of Britain�s Houses  of Parliament.

The Paris guns were moved on railway tracks; they bombarded the city  for 140 days. Their unprecedented range of 75 mi (121 km) was achieved  by sending the shells on a trajectory 12 mi (19 km) into the stratosphere.  They were nicknamed for the Krupp matriarch Bertha von Bohlen.</p><p>Big Cypress Swamp Swamp region whose eastern half is a national  preserve, southern Florida, U.S. Covering 2,400 sq mi (6,200 sq km), the  region merges with the swampy Everglades on the east and south. It is  dominated by cypress trees, and wildlife is abundant. The Seminole Indi�  ans have reservations in the area.</p><p>Big Stick Policy Policy named by Pres. Theodore Roosevelt to describe  the assertion of U.S. dominance as a moral imperative. It was taken from  an African proverb, �Speak softly and carry a big stick; you will go far.�  Roosevelt first used it when he asked Congress for money to increase U.S.  naval preparedness to support his diplomatic objectives. The press used  the phrase to describe Roosevelt�s Latin America policy and his domes�  tic policy of regulating monopolies.</p><p>Big Sur Scenic region along the Pacific coast of California, U.S. It com�  prises a ruggedly beautiful stretch of seacoast 100 mi (160 km) long.  Popular with tourists and naturalists, it extends southward from Carmel  to the Hearst Castle at San Simeon. A narrow, mountainous coastal road  affords views of the Pacific Ocean and the wilderness areas of the Los  Padres National Forest. The Pfeiffer-Big Sur State Park contains the town  of Big Sur and borders the Big Sur River. The home of Robinson Jeffers  is a local landmark.</p><p>big tree or giant sequoia or Sierra redwood Coniferous ever�  green ( Sequoiadendron giganteum ; see conifer) found in scattered groves  on the western slopes of the Sierra Nevada range of California, U.S. The  largest of all trees in bulk, the big tree is distinguished from the coastal  redwood ( Sequoia sempervirens) by having uniformly scalelike, or awl-  shaped, leaves that lie close against the branches, scaleless winter buds,  and cones requiring two seasons to mature. The pyramidal tree shape,  reddish brown furrowed bark, and drooping branches are common to both  genera. The largest specimen (in total bulk) is the General Sherman tree  in Sequoia National Park �101.5 ft (31 m) in circumference at its base,  272.4 ft (83 m) tall, and weighing an estimated 6,167 tons (5,593 metric  tons). Because big-tree lumber is more brittle than redwood lumber and  thus less desirable, the big tree has been easier to preserve; though some  groves have been cut, most of the 70 remaining groves are now protected  by state or national forests or parks.</p><p>Bigfoot or Sasquatch Large, hairy, humanlike creature that report�  edly lives in isolated areas of the northwestern U.S. and western Canada.  Descriptions of Bigfoot are similar to those of the Abominable Snowman  of the Himalayas. It is said to be a primate 6-15 ft (2-4.5 m) in height,  walking upright and either moving silently or emitting a high-pitched cry.  Supposed footprints (some are hoaxes) have measured up to 24 in. (60  cm) in length. Despite many reported sightings, there is still no solid evi�  dence that Bigfoot exists.</p><p>bighorn or mountain sheep Stocky, climbing hoofed mammal  (Ovis canadensis ) of western North  America. Both sexes have horns that  in the male may curve in a spiral  more than 39 in. (1 m) long. Their  fur is usually brown with a whitish  rump patch. The related thinhom, or  Dali�s sheep ( O. dalli ), of Alaska and  Canada is similar to the bighorn.</p><p>Both species are about 39 in. (1 m)  tall at the shoulder, but the bighorn  is heavier, weighing up to 300 lb  (136 kg). They live in small groups  among remote crags and cliffs of  mountainous areas and feed mainly  on grasses. Bighorn rams compete  for females by launching themselves  at each other from a few yards� dis�  tance and clashing horns.</p><p>Bighorn Mountains Mountain range, southern Montana and northern  Wyoming, U.S. It is a range of the northern Rocky Mountains extending  120 mi (193 km), rising abruptly 4,000-5,000 ft (1,200-1,500 m) above</p><p>the Great Plains and Bighorn Basin. The highest summit is Wyoming�s  Cloud Peak, at 13,165 ft (4,013 m). Bighorn National Forest covers part  of the range. On Medicine Mountain is the Medicine Wheel, a prehistoric  stone-spoked circle 70 ft (20 m) in diameter.</p><p>Bighorn River River, Wyoming and Montana, U.S. Formed by the  confluence of the Popo Agie and Wind rivers in west-central Wyoming,  it flows north 336 mi (541 km) into the Yellowstone River in southeastern  Montana. The Little Bighorn joins the main stream at Hardin, Mont. The  Bighorn Canyon National Recreation Area stretches along the Montana-  Wyoming border. See also Battle of the Little Bighorn.</p><p>Bihar \bi-'har\ State (pop., 2001: 82,998,509), northeastern India. Bor�  dered by Nepal and West Bengal, Jharkhand, and Uttar Pradesh states, it  occupies 38,301 sq mi (99,200 sq km); its capital is Patna. Its limits are  nearly the same as those of the ancient kingdoms of Videha and Magadha.  In the 4th century ad the area came under the Gupta empire, whose capi�  tal was at Pataliputra (Patna). Overcome by the Muslims c. 1200, Bihar  was annexed to Delhi in 1497. Taken by the British in 1765, it was made  part of Bengal. The area was the scene of revolts against the British in the  mid-19th century and of Mohandas K. Gandhi�s nonviolent movement in  the early 20th century. Bihar was made a province of British India in 1936;  in 1950 it became a state in independent India. It is one of India�s least  urbanized states, and most of its population engages in agriculture. In  2000 the state of Jharkhand was created from Bihar�s southern districts.</p><p>Bikini Atoll, western Marshall Islands, central Pacific Ocean. It consists  of a ring of 20 small coral islands. Administered by the U.S. from 1947  as part of a UN-sanctioned U.S. Trust Territory of the Pacific Islands, it  was used for U.S. nuclear-weapons testing in 1946-58. The 166 inhab�  itants were removed before the tests began and returned in 1969, but they  were evacuated again in 1978 because of high radiation levels. Cleanup  there continued, and in the late 1990s Bikini was again deemed safe for  habitation. The atoll became part of the Republic of the Marshall Islands  in 1979.</p><p>Biko Vbe-ko\, Stephen (b. Dec. 18, 1946, King William�s Town,  S.Af.�d. Sept. 12, 1977, Pretoria) South African political activist. A  former medical student, in 1968 he founded the Black Consciousness  movement, designed to raise black awareness of apartheid oppression. He  was officially �banned� by the South African government in 1973 and was  arrested several times in 1976-77. His death from head injuries suffered  in police custody made him an international martyr for South African  black nationalism. The initial inquest absolved the police of wrongdoing,  but in 1997 five former officers confessed to Biko�s murder.</p><p>Bilbao \bil-'ba-,o, bil-'bau\ Port city (pop., 2001: city, 349,972; metro,  area, 947,334), northern Spain. It is located 7 mi (11 km) inland from the  Bay of Biscay. The largest city in the Basque Country, it originated as a  settlement of mariners and ironworkers and was chartered in 1300. In the  18th century it prospered through trade with Spain�s New World colonies.  The city was sacked by French troops in the Peninsular War (1808) and  besieged during the Carlist Wars (see Carlism). It is a chief port in Spain  and a centre of the metallurgical industries, shipbuilding, and banking.  Landmarks include the 14th-century Cathedral of Santiago and the 20th-  century Guggenheim Museum Bilbao.</p><p>bilberry Low-growing deciduous shrub ( Vaccinium myrtillus) of the  heath family, found in woods and on heaths, chiefly in hilly districts of  Britain, northern Europe, and Asia. The stiff stems bear small egg-shaped  leaves and small rosy flowers tinged with green. The dark blue, waxy ber�  ries are an important food of the grouse and are used for tarts and pre�  serves. They are borne singly, unlike those of the much more productive  cultivated blueberries of the U.S. ( V. australe ), which are borne in long  clusters.</p><p>bildungsroman \'bil- l duqz-ro-,man\ German "novel of character  development" Class of novel in Gentian and other literature that deals  with the formative years of the main character, whose moral and psycho�  logical development is depicted. It ends on a positive note, with the hero�s  foolish mistakes and painful disappointments behind him and a life of  usefulness ahead. It grew out of folklore tales in which a dunce goes out  into the world seeking adventure. The first novelistic development of the  theme, Johann W. von Goethe�s Wilhelm Meister�s Apprenticeship (1795�  96), remains a classic example.</p><p>bile Greenish-yellow liver secretion passed to the gallbladder for con�  centration, storage, or transport into the duodenum for fat digestion.

It may be acquired early  by children in regions where most adults speak two languages (e.g.,  French and dialectal German in Alsace). Children may also become bilin�  gual by learning languages in two different social settings; for example,  British children in British India learned an Indian language from their  nurses and family servants. A second language can also be acquired in  school. Bilingualism can also refer to the use of two languages in teach�  ing, especially to foster learning in students trying to learn a new lan�  guage. Advocates of bilingual education in the U.S. argue that it speeds  learning in all subjects for children who speak a foreign language at home  and prevents them from being marginalized in English-language schools.  Detractors counter that it hinders such children from mastering the lan�  guage of the larger society and limits their opportunities for employment  and higher education.</p><p>bill See beak</p><p>Bill, Max (b.

He studied architecture, metalwork, stage design, and painting at the Bau-  haus. In 1930 he opened his own studio in Zurich, where he spent most  of his life and earned a living designing advertisements. In the 1940s he  designed chairs featuring geometric forms. He cofounded and directed the  College of Design in Ulm, Ger. (1951-55), and also designed its build�  ings. He is best known for his advertising designs.</p><p>bill of exchange Short-term negotiable financial instrument consist�  ing of a written order addressed by the seller of goods to the buyer requir�  ing the latter to pay a certain sum of money on demand or at a future  time. Bills of exchange are often used in international transactions, and  the holder of such a bill may redeem it in cash immediately by selling it  to a bank at a discount. Bills of exchange used in domestic transactions  are sometimes called drafts. See also promissory note.</p><p>Bill of Rights (1689) British law, one of the basic instruments of the  British constitution. It incorporated the provisions of the Declaration of  Rights, which William III and Mary II accepted upon taking the throne. Its  main purpose was to declare illegal various practices of James II, such as  the royal prerogative of dispensing with the law in certain cases. The result  of a long struggle between the Stuart kings and the English people and  Parliament, it made the monarchy clearly conditional on the will of Par�  liament and provided freedom from arbitrary government. It also dealt  with the succession to the throne.</p><p>Bill of Rights First 10 amendments to the Constitution of the United  States, adopted as a group in 1791. They are a collection of guarantees  of individual rights and of limitations on federal and state governments  that derived from popular dissatisfaction with the limited guarantees of  the Constitution. The first Congress submitted 12 amendments (drafted  by James Madison) to the states, 10 of which were ratified. The 1st Amend�  ment guarantees freedom of religion, speech, and the press and grants the  right to petition for redress and to assemble peacefully. The 2nd Amend�  ment guarantees the right of the people to keep and bear arms. The 3rd  prohibits the quartering of soldiers in private dwellings in peacetime. The  4th protects against unreasonable search and seizure. The 5th establishes  grand-jury indictment for serious offenses, protects against double jeopardy  in criminal cases, and prohibits compelling testimony by a person against  himself. The 6th establishes the rights of the accused to a speedy trial and  an impartial jury and guarantees the right to legal counsel and to the  obtaining of witnesses in his favour. The 7th preserves the right to trial  by jury in serious civil suits and prohibits double jeopardy in civil cases.  The 8th prohibits excessive bail and cruel and unusual punishment. The  9th states that enumeration of certain rights in the Constitution does not  mean the abrogation of rights not mentioned. The 10th reserves to the  states and people any powers not delegated to the federal government.</p><p>billfish Any of several long-jawed fishes, especially those in the family  Istiophoridae, including marlins, spearfishes, and SAiLFiSHes. The name is  also applied to the gar, needlefish, and sauries (family Scomberesocidae),  as well as to the swordfish (family Xiphiidae).</p><p>billiards Any of various games played on a cloth-topped, cushion-railed  rectangular table by driving small, hard balls against one another or into</p><p>pockets with a long stick called a cue. Carom, or French billiards, is  played with three balls, two white and one red, on a table without pockets.  The object is to stroke the white cue ball so that it hits the two object balls  in succession, scoring a carom (one point). English billiards is also played  with three balls but on a pocketed table; it is scored in various ways.  Snooker is another popular British billiards game. The principal billiards  game in North America is pocket billiards, or pool. The Billiard Congress  of America controls U.S. tournament play, including the U.S. Open Pock�  ets Billiard Championship, regarded as the world championship.</p><p>Billings City (pop., 2000: 89,847), south-central Montana, U.S. Origi�  nally settled on the Yellowstone River in 1877 as Coulson, Billings was  renamed in 1882 in honour of Frederick Billings, president of the North�  ern Pacific Railway Company. It is now a trading and shipping point for  wool, livestock, and agriculture. Nearby Pictograph Cave State Monu�  ment has prehistoric artifacts.</p><p>Billings, John Shaw (b. April 12, 1838, Switzerland county, Ind.,  U.S.�d. March 11, 1913, New York, N.Y.) U.S. surgeon and librarian.  He worked for the U.S. Army 1861-95. He fostered the growth of the  surgeon general�s library in Washington, D.C., developing what would  become the National Library of Medicine, the world�s largest medical  reference centre. He founded the monthly Index Medicus (1879), still one  of the primary U.S. medical bibliographies, and published the first Index  Catalogue (1880-95). He also designed Johns Hopkins Hospital and was  its medical adviser, ran national vital statistics programs, led the U.S.  effort to end yellow fever, and was the first director of the New York Pub�  lic Library. His organization of U.S. medical institutions was central to  modernization of hospital care and maintenance of public health.</p><p>Billings, William (b. Oct. 7, 1746, Boston, Mass.�d. Sept. 26, 1800,  Boston, Mass., U.S.) American hymn composer, sometimes called the first  American composer. A tanner by trade, he was largely self-taught in  music. His robust and primitive style, lacking instrumental parts, has  seemed to embody the distinctive virtues of early America. His New  England Psalm-Singer {111 0) was the first published collection of Ameri�  can music; his other works include The Singing Master�s Assistant (1778)  and The Continental Harmony (1794).</p><p>Billiton \be-'le-,ton\ or Belitung Xba-'le-.tuqN Island, Bangka-Belitung  province, west-central Indonesia. Lying on the Karimata Strait between  the islands of Bangka (west) and Borneo (northeast), it is situated between  the South China Sea (north) and Java Sea (south). It is some 55 mi (90  km) long and 45 mi (70 km) wide, with an area of about 1,850 sq mi  (4,800 sq km). The main town and port is Tanjungpandan. Billiton was  ceded to the British in 1812 by the sultan of Palembang, Sumatra, but  Britain recognized the Dutch claim in 1824. The island became part of  Indonesia after World War II. It is important for its tin mines, discovered  in 1851.</p><p>Billroth Vbil-rot\, (Christian Albert) Theodor (b. April 26, 1829,  Bergen auf Riigen, Prussia�d. Feb. 6, 1894, Abbazia, Austria-Hungary)  Austrian surgeon. He pioneered the study of bacterial causes of wound  fever and adopted early the antiseptic techniques that eradicated the threat  of fatal surgical infections. The founder of modem surgery of the abdomi�  nal cavity, he altered and removed organs previously considered inacces�  sible. In 1872 he was the first to remove part of an esophagus, joining the  ends together; later he performed the first complete larynx removal. In  1881, when he had made intestinal surgery almost commonplace, he suc�  cessfully removed a cancerous pylorus (lower end of the stomach).</p><p>Billy the Kid orig. William H.

As a child he migrated with his family to Kan�  sas, then lived in New Mexico from c. 1868. His career of lawlessness  throughout the Southwest began early; by the time he was captured by  Sheriff Pat Garrett in 1880 he had allegedly killed 27 men. Convicted in  New Mexico in 1881 and sentenced to hang, he escaped from jail, kill�  ing two deputies, and remained at large until Garrett tracked him down  and killed him.</p><p>Biloxi \bi-'l3k-se, bi-'lak-se\ Coastal city (pop., 2000: 50,644), south�  eastern Mississippi, U.S. Located east of Gulfport on the Gulf of Mexico,  it was first settled as Fort Louis (established 1719); a nearby earlier fort,  Fort Maurepas, was the lower Mississippi valley�s first permanent Euro�  pean settlement (1699).

In  the 19th century, a bimetallic system defined a nation�s monetary unit by  law in terms of fixed quantities of gold and silver (thus automatically  establishing a rate of exchange between the two metals). The system pro�  vided a free and unlimited market for the two metals, imposed no restric�  tions on the use and coinage of either metal, and made all other money in  circulation redeemable in either gold or silver. Because each nation inde�  pendently set its own rate of exchange between the two metals, the result�  ing rates of exchange often differed widely from country to country. When  the ratio of the official prices proved different from the ratio of prices in  the open market, Gresham's law operated in such a way that coins of only  one metal remained in circulation. A monometallic system using the gold  standard proved more responsive to changes in supply and demand and  was widely adopted after 1867. See also exchange rate; silver standard.</p><p>bin Laden, Osama (b. 1957, Riyadh, Saud.Ar.) Leader of a broad-  based Islamic extremist movement implicated in numerous acts of ter�  rorism against the U.S. and other Western countries. The son of a wealthy  Saudi family, he joined the Muslim resistance in Afghanistan after the  1979 Soviet invasion of that country. Following his homecoming, he  became enraged at the presence of U.S. troops in Saudi Arabia during the  Persian Gulf War (1990-91) and, through a network of like-minded  Islamic militants known as al-Qaeda, launched a series of terrorist attacks.  These acts included the bombings of the World Trade Center in New York  City in 1993, the U.S. embassies in Kenya and Tanzania in 1998, and the  U.S. warship Cole in Aden, Yemen, in 2000. A self-styled Islamic scholar,  bin Laden issued several legal opinions calling on Muslims to take up  jihad (holy war) against the U.S., and in 2001 a group of militants under  his direction launched the September 11 attacks, which led to the deaths  of some 3,000 people. The U.S. thereafter demanded bin Laden�s extra�  dition from Afghanistan, where he was sheltered by that country�s Tali�  ban militia, and launched attacks on Taliban and al-Qaeda forces when  that ultimatum was not met. With the collapse of the Taliban, bin Laden  and his associates went into hiding.</p><p>binary code Code used in digital computers, based on a binary number  system in which there are only two possible states, off and on, usually  symbolized by 0 and 1. Whereas in a decimal system, which employs 10  digits, each digit position represents a power of 10 (100, 1,000, etc.), in  a binary system each digit position represents a power of 2 (4, 8, 16, etc.).  A binary code signal is a series of electrical pulses that represent num�  bers, characters, and operations to be performed. A device called a clock  sends out regular pulses, and components such as transistors switch on  (1) or off (0) to pass or block the pulses. In binary code, each decimal  number (0-9) is represented by a set of four binary digits, or bits. The four  fundamental arithmetic operations (addition, subtraction, multiplication,  and division) can all be reduced to combinations of fundamental Bool�  ean algebraic operations (see Boolean algebra) on binary numbers.</p><p>binary star Pair of stars in orbit around a common centre of gravity.  Their relative sizes and brightnesses and the distance between them vary  widely. Perhaps half of all stars in the Milky Way Galaxy are binaries or  members of more complex multiple systems. Some binaries form a class  of variable stars (see eclipsing variable star). Stars can be identified as bina�  ries in various ways�visually by telescope, through spectroscopic obser�  vation, by changes in apparent brightness (when the dimmer star eclipses  its companion), or by changes in the proper motion of the visible member  (owing to the gravitational pull of the invisible companion).</p><p>binding energy Energy required to separate a particle from a system  of particles or to disperse all the particles of a system. Nuclear binding  energy is the energy required to separate an atomic nucleus into its con�  stituent protons and neutrons. It is also the energy that would be released  by combining individual protons and neutrons into a single nucleus. Elec�  tron binding energy, or ionization potential, is the energy required to  remove an electron from an atom, molecule, or ion, and also the energy  released when an electron joins an atom, molecule, or ion. The binding  energy of a single proton or neutron in a nucleus is about a million times  greater than that of a single electron in an atom.</p><p>bindweed Any plant of the closely related genera Convolvulus and  Calystegia , mostly twining, often weedy, and producing funnel-shaped  flowers. Bellbine, or greater bindweed ( Calystegia sepium), native in Eur�  asia and North America, is a twining perennial that grows from creeping,  underground stems and is common in hedges and woods and along road�  sides. Sea bindweed (C. soldanella ) creeps along European seaside sand  and gravel. Several Convolvulus species are widespread or conspicuous.  The weedy perennial field bindweed (C. arvensis), European but widely  naturalized in North America, twines around crop plants and along road�  sides. Scammony, a purgative, is derived from the rhizomes of C. scam-  monia, a trailing perennial native to western Asia. Rosewood oil comes  from certain species of Convolvulus.</p><p>Binet \bi-'na\, Alfred (b. July 8, 1857, Nice, France�d. Oct. 18, 1911,  Paris) French psychologist. His interest in Jean-Martin Charcot�s work on  hypnosis prompted him to abandon a law career and study medicine at  the Salpetriere Hospital in Paris (1878-91). He served as director of a  research laboratory at the Sorbonne (1895-1911). A major figure in the  development of experimental psychology in France, he founded L 'Annie  Psychologique, the first French journal on psychology, in 1895. He devel�  oped experimental techniques to measure reasoning ability; between 1905  and 1911 he and Theodore Simon developed influential scales for the  measurement of intelligence of children. His works include Experimen�  tal Study of Intelligence (1903) and A Method of Measuring the Devel�  opment of the Intelligence of Young Children (1915).</p><p>Binford, Lewis R(oberts) (b.

When a num�  ber on the card is drawn, the players cover that number (should they have  it); the game is won by covering a certain number of squares in a row (ver�  tically, horizontally, or diagonally). Cards are purchased and proceeds are  placed into a common �pot�; winning cards are awarded a portion of the  pot. Wildly popular in the mid 20th century, bingo has in recent decades  suffered a decline in America but has increased in popularity in other parts  of the world. The earliest name for bingo�lotto�was recorded in Britain  in 1776; the game is sometimes called keno in the U.S.</p><p>Binh Dinh Vuong See Le Loi</p><p>binoculars Optical instrument for providing a magnified view of dis�  tant objects, consisting of two similar telescopes, one for each eye,  mounted on a single frame. In most binoculars, each telescope has two  prisms, which reinvert the inverted image provided by the eyepiece of each  telescope. Light rays travel along a folded path inside the telescopes, so  the instrument has a shorter overall length. The prisms also provide bet�  ter depth perception at greater distances, by allowing the two objectives  (object lenses) to be set farther apart than the eyepieces. Binocular eye�  pieces are often fitted to microscopes or other optical instruments.</p><p>binomial nomenclature System of naming organisms in which each  organism is indicated by two words, the genus (capitalized) and species  (lowercase) names, both written in italics. For example, the tea rose is  Rosa odorata ; the common horse is Equus caballus. The system was  developed by Carolus Linnaeus in the mid 18th century. The number of  binomial names proliferated as new species were established and more  categories were formed, and by the late 19th century the nomenclature of  many groups of organisms was confused. International committees in the  fields of zoology, botany, bacteriology, and virology have since estab�  lished rules to clarify the situation. See also taxonomy.</p><p>binomial theorem In algebra, a formula for expansion of the bino�  mial (x + y ) raised to any positive integer power. A simple case is the  expansion of ( x + y) 2 , which is x 2 + 2xy + y 2 . In general, the expression  (x + y) n expands to the sum of {n + l)terms in which the power of x  decreases from n to 0 while the power of y increases from 0 to n in suc�  cessive terms. The terms can be represented in factorial notation by the  expression [n\/((n - r)!r!)]x� - r y r in which r takes on integer values from  0 to n.</p><p>Bio-Bio \,be-6-'be-o\ River River, south-central Chile. Rising in the  Andes Mountains, it flows northwestward 240 mi (380 km) to enter the  Pacific Ocean near Concepcion. Though it is one of Chile�s longest riv�  ers, it is shallow and navigable only by flat-bottomed boats.</p><p>biochemistry Field of science concerned with chemical substances and  processes that occur in plants, animals, and microorganisms. It involves  the quantitative determination and structural analysis of the organic com�  pounds that make up cells (proteins, carbohydrates, and lipids) and of those  that play key roles in chemical reactions vital to life (e.g., nucleic acids,  vitamins, and hormones). Biochemists study cells� many complex and inter�  related chemical changes. Examples include the chemical reactions by  which proteins and all their precursors are synthesized, food is converted  to energy (see metabolism), hereditary characteristics are transmitted (see  heredity), energy is stored and released, and all biological chemical reac�  tions are catalyzed (see catalysis, enzyme). Biochemistry straddles the bio�  logical and physical sciences and uses many techniques common in  medicine and physiology as well as those of organic, analytical, and physi�  cal chemistry.</p><p>biochip Small-scale device, analogous to an integrated circuit, con�  structed of or used to analyze organic molecules associated with living  organisms. One type of theoretical biochip is a small device constructed of  large organic molecules, such as proteins, and capable of performing the  functions (data storage, processing) of an electronic computer. The other  type of biochip is a small device capable of performing rapid, small-scale  biochemical reactions for the purpose of identifying gene sequences, envi�  ronmental pollutants, airborne toxins, or other biochemical constituents.</p><p>biodegradability Capacity of a material to decompose by biological  action. The term usually refers to the environmental breakdown of waste  by microorganisms. Generally, plant and animal products are biodegrad�  able, whereas mineral substances (e.g., metals, glass, plastics) are not.  Local conditions, especially the presence or absence of oxygen, affect  biodegradability. Disposal of nonbiodegradable waste is a primary source  of pollution. Surgical materials made to be absorbed by the body are also  called biodegradable.</p><p>biodiversity Quantity of plant and animal species found in a given  environment. Sometimes habitat diversity (the variety of places where  organisms live) and genetic diversity (the variety of traits expressed within  a species) are also considered types of biodiversity. The estimated 3-30  million species on Earth are divided unequally among the world�s habi�  tats, with 50-90% of the world�s species living in tropical regions. The  more diverse a habitat, the better chance it has of surviving a change or  threat to it, because it is more likely to be able to make a balancing  adjustment. Habitats with little biodiversity (e.g., Arctic tundra) are more  vulnerable to change. The 1992 Earth Summit resulted in a treaty for the  preservation of biodiversity.</p><p>bioengineering Application of engineering principles and equipment  to biology and medicine. It includes the development and fabrication of  life-support systems for underwater and space exploration, devices for  medical treatment (see dialysis, prosthesis), and instruments for monitoring  biological processes. Development has been particularly rapid in the area  of artificial organs, which culminated in the implantation of an artificial  heart into a human being in 1982. Bioengineers also develop equipment  that enables humans to maintain body functions in hostile environments,  such as the space suits worn by astronauts during extravehicular maneu�  vers.</p><p>biofeedback Information supplied instantaneously about an individu�  al�s own physiological processes. Data concerning cardiovascular activ�  ity (blood pressure and heart rate), temperature, brain waves, or muscle  tension is monitored electronically and returned or �fed back� to the indi�  vidual through a gauge on a meter, a light, or a sound. The goal is for the  patient to use that biological data to learn to voluntarily control the body�s  reactions to stressful external events. A type of behaviour therapy, biofeed�  back training is sometimes used in combination with psychotherapy to help  patients understand and change their habitual reactions to stress. Com�  plaints treated through biofeedback include migraine headaches, gas�  trointestinal problems, high blood pressure, and epileptic seizures.</p><p>biography Form of nonfictional literature whose subject is the life of  an individual. The earliest biographical writings probably were funeral  speeches and inscriptions. The origins of modern biography lie with Plu�  tarch�s moralizing lives of prominent Greeks and Romans and Suetonius�s  gossipy lives of the Caesars. Few biographies of common individuals  were written until the 16th century. The major developments of English  biography came in the 18th century, with such works as James Boswell�s  Life of Johnson. In modern times impatience with Victorian reticence and  the development of psychoanalysis have sometimes led to a more pen�  etrating and comprehensive understanding of biographical subjects. See  also AUTOBIOGRAPHY.</p><p>Bioko \be-'o-ko\ formerly Fernando Po \fer-'nan-do-'po\ Island  (pop., 1987 est.: 67,920), Bight of Biafra, West Africa. It lies 100 mi (160  km) northwest of continental Equatorial Guinea, of which it is a part.  Bioko became the official name in 1979. Volcanic in origin, with an area  of 779 sq mi (2,018 sq km), it rises sharply from the sea; its highest point  is Santa Isabel Peak, at 9,869 ft (3,008 m). Malabo, the country�s capital,  is located on Bioko. The island was visited by the Portuguese explorer  Fernao Po, probably in 1472. Though the island was claimed by Spain  after 1778, the first attempt at firm Spanish control came only in 1858.  The original inhabitants, the Bubi, are descendants of Bantu-speaking  migrants from the mainland. Many Fang have flocked to the island from  the continent.</p><p>biological rhythm Periodic biological fluctuation in an organism cor�  responding to and in response to periodic environmental change, such as  day and night or high and low tide. The internal mechanism that main�  tains this rhythm even without the apparent environmental stimulus is a  �biological clock.� When the rhythm is interrupted, the clock�s adjust�  ment is delayed, accounting for such phenomena as jet lag when travel�  ing across time zones. Rhythms may have 24-hour (circadian rhythm),  monthly, or annual cycles. See also photoperiodism.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>biological warfare &#x25BA; biotite I 221</p><p>biological warfare or germ warfare Military use of disease-  producing or poisonous agents, and the means for defending against such  agents. Biological warfare agents include many bacteria, such as those  which cause anthrax, brucellosis, and typhus; viruses that cause diseases  such as equine encephalitis; fungi such as rice blast, cereal rust, wheat smut,  and potato blight; and toxins such as botulinum and ricin that are extracted  from living organisms. Biological warfare dates from ancient times when  warring groups would try to poison enemy soldiers with rotting or dis�  eased corpses, infect cattle and horses, or spread contagion through civil�  ian populations. Following the horrors of World War I, a 1925 Geneva  Protocol prohibited the use of biological agents in warfare; however, this  did not prevent Japan from using them in China during World War II.  During the Cold War the Soviet Union as well as the U.S. and its allies  built huge stockpiles of biological agents. Both sides signed the 1972  Biological Weapons Convention, which prohibits the production, stock�  piling, or development of biological weapons and requires the destruction  of existing stockpiles, but the Soviets conducted a clandestine program  until the 1990s. Biological weapons programs can be concealed easily,  and the 1972 convention contains no provisions for inspection and report�  ing. As a result, many states have been suspected of developing biologi�  cal warfare agents, and some modern armed forces have prepared  defensive measures. These include battlefield sensors, protective garments  and masks, sterilizing agents, and vaccines.</p><p>biology Study of living things and their vital processes. An extremely  broad subject, biology is divided into branches. The current approach is  based on the levels of biological organization involved (e.g., molecules,  cells, individuals, populations) and on the specific topic under investiga�  tion (e.g., structure and function, growth and development). According to  this scheme, biology�s main subdivisions include morphology, physiology,  taxonomy, embryology, genetics, and ecology, each of which can be further  subdivided. Alternatively, biology can be divided into fields especially  concerned with one type of living thing; for example, botany (plants),  zoology (animals), ornithology (birds), entomology (insects), mycology  (fungi), microbiology (microorganisms), and bacteriology (bacteria). See  also biochemistry; molecular biology.</p><p>biology, philosophy of Philosophical investigation of the concepts,  problems, and methods of the biological sciences. Many of the topics  considered in contemporary philosophy of biology have arisen from  reflection on aspects of the theory of evolution. They include the question  of whether evolution is ultimately falsifiable, a conventional requirement  of all scientific theories; whether the thesis of natural selection has empiri�  cal content or is merely a tautology; whether selection operates at the level  of the individual, the species, or the gene; and whether selection is guided  by certain constraints controlling development at the molecular level.  Other more general issues concern the possible reduction of biological  theories to theories of the physical sciences, the role of teleological lan�  guage in biology (see teleology), and the nature of species as a biological  category. See also creationism; sociobiology.</p><p>bioluminescence \ l bI-o- l lii-m3- , ne-s 3 ns\ Emission of light by an  organism or biochemical system (e.g., the glow of bacteria on decaying  meat or fish, the phosphorescence of protozoans in tropical seas, the  flickering signals of fireflies). It occurs in a wide range of protists and  animals, including bacteria and fungi, insects, marine invertebrates, and  fish. It is not known to exist naturally in true plants or in amphibians,  reptiles, birds, or mammals. It results from a chemical reaction that pro�  duces radiant energy very efficiently, giving off very little heat. The essen�  tial light-emitting components are usually the organic molecule luciferin  and the enzyme luciferase, which are specific for different organisms. In  higher organisms, light production is used to frighten predators and to  help members of a species recognize each other. Its functional role in  lower organisms such as bacteria, dinoflagellates, and fungi is uncertain.  Luminous species are widely scattered taxonomically, with no clear-cut  pattern, though most are marine.</p><p>biomass Weight or total quantity of living organisms of one animal or  plant species (species biomass) or of all the species in the community  (community biomass), commonly referred to as a unit area or volume of  the habitat. The biomass in an area at a given moment is the standing  crop.</p><p>biome Vbi-.omV Largest geographic biotic unit, a major community of  plants and animals with similar requirements of environmental conditions.  It includes various communities and developmental stages of communi�</p><p>ties and is named for the dominant type of vegetation, such as grassland  or coniferous forest. Several similar biomes constitute a biome type; for  example, the temperate deciduous forest biome type includes the decidu�  ous forest biomes of Asia, Europe, and North America. The standard  European term for biome is �major life zone.�</p><p>Biondi \be-'an-de\, Matt (b. Oct. 15, 1965, Palo Alto, Calif., U.S.) U.S.  swimmer. Biondi, 6 ft 7 in.

Along with Mark Spitz, he is the most successful U.S. swimmer in Olym�  pic history.</p><p>biophysics Discipline concerned with applications of the principles and  methods of the physical sciences to biological problems. Biophysics deals  with biological functions that depend on physical agents such as electric�  ity or mechanical force, with the interaction of living organisms with  physical agents such as light, sound, or ionizing radiation, and with inter�  actions between living things and their environment as in locomotion,  navigation, and communication. Its subjects include bone, nerve impulses,  muscle, and vision as well as organic molecules, using such tools as paper  chromatography and X-ray crystallography.</p><p>biopsy \'bl-,ap-se\ Procedure in which cells or tissues are removed from  a patient and examined. The sample may be obtained from any organ, by  any of several methods, including suction through a needle, swabbing,  scraping, endoscopy, and cutting out the entire structure or part of it to be  tested. Biopsy is a standard step in distinguishing malignant from benign  tumours and can provide other information for diagnosis, particularly  concerning such organs as the liver or pancreas. Slides of the tissue are  prepared and examined by microscope.</p><p>BIOS VbI-,os\ in full Basic Input/Output System Computer pro�  gram that is typically stored in EPROM and used by the CPU to perform  start-up procedures when the computer is turned on. Its two major pro�  cedures are determining what peripheral devices (keyboard, mouse, disk  drives, printers, video cards, etc.) are available and loading the operating  system (OS) into main memory. After start-up, the BIOS program man�  ages data flow between the OS and the peripherals, so neither the OS nor  the application programs need to know the details of the peripherals (such  as hardware addresses).</p><p>biosolids Sewage sludge, the residues remaining from the treatment of  sewage. For use as a fertilizer in agricultural applications, biosolids must  first be stabilized through processing, such as digestion or the addition of  lime, to reduce concentrations of heavy metals and harmful organisms  (certain bacteria, viRUSes, and other pathogens). This processing also  reduces the volume of material and stabilizes the organic matter in it, thus  reducing the potential for odours. Use of biosolids in agriculture has  become controversial, critics claiming that even treated sewage may har�  bour harmful bacteria, viruses, and heavy metals.</p><p>biosphere Relatively thin life-supporting stratum of the earth�s surface,  extending from a few miles into the atmosphere to the deep-sea vents of  the oceans. The biosphere is a global ecosystem that can be broken down  into regional or local ecosystems, or biomes. Organisms in the biosphere  are classified into trophic levels (see food chain) and communities.</p><p>biotechnology Application to industry of advances made in the bio�  logical sciences. The growth of the field is linked to the development in  the 1970s of genetic engineering and to the 1980 U.S. Supreme Court deci�  sion that �a live human-made microorganism is a patentable matter,�  which resulted in the establishment of numerous commercial biotechnol�  ogy firms that manufacture genetically engineered substances for a vari�  ety of mostly medical, agricultural, and ecological uses.</p><p>biotin Vbl-o-tonX Organic compound, part of the vitamin B complex, essen�  tial for growth and well-being in animals and some microorganisms.

It functions in the  formation and metabolism of fats and carbohydrates. It is widely distrib�  uted in nature and is especially abundant in egg yolk, beef liver, and yeast.  A biotin deficiency can be induced by consuming large amounts of raw  egg white, which contains a protein (avidin) that combines with biotin  and makes it unavailable.

Located between the Lebanon and  Anti-Lebanon mountain ranges, it is about 75 mi (120 km) long and 10  mi (15 km) wide. Traversed by the upper Orontes and Litani rivers, the  valley is an agricultural area. The ruins of the ancient city of Baalbeck are  located there. The majority of the inhabitants are Shl'ite Muslims. The  region was the scene of some factional fighting during the Lebanese Civil  War (1975-90), and during that time Israel intermittently fought there  against forces of the Palestine Liberation Organization and the Syrian army.  Since the 1980s the region has been a stronghold of the Shl'ite militant  organization Hezbollah.</p><p>birch Any of about 40 species of short-lived ornamental and timber trees  and shrubs of the genus Betula, the largest genus of the family Betulaceae,  which also contains alders, filberts, Carpinus (hornbeam), and the genera  Ostrya and Ostryopsis. Birches are found throughout cool regions of the  Northern Hemisphere; other members of the family Betulaceae are found  in temperate and subarctic areas of the Northern Hemisphere, in tropical  mountains, and in South America through the Andes as far south as Argen�  tina. Leaves are simple, serrate, and alternate; male and female flowers  (catkins) are borne on the same plant. The fruit is a small nut or short�  winged samara (dry, winged fruit).

Birds have a four-chambered heart  (like mammals), forelimbs modified into wings, and keen vision, and their  eggs have calcium-rich eggshells. Their sense of smell is not highly devel�  oped. Birds are found almost worldwide in diverse habitats on both land  and water. Dietary preferences and nest structure vary widely. Almost all  species incubate their eggs. Flying birds have evolved skeletons in which  part of the bone is replaced by air spaces, an adaptation for reducing  weight. The crop, an enlarged part of the esophagus used for temporary  food storage, enables birds to feed while in flight. Humans use wild and  domesticated birds and their eggs for food, hunt wild birds for sport, and  use feathers for decoration and insulation. More than 1,000 extinct spe�  cies of bird have been identified from fossil remains; the earliest fossil  bird known is Archaeopteryx.</p><p>Bird, Larry (Joe) (b. Dec. 7, 1956, West Baden, Ind., U.S.) U.S. bas�  ketball player. Bird spent most of his collegiate career at Indiana State  University, before being drafted by the Boston Celtics of the National  Basketball Association (NBA). Playing forward and standing 6 ft 9 in.  (2.06 m) tall, he was a great shooter and ball handler and one of the most  formidable playmakers in the game. He helped lead Boston to NBA cham�  pionships in 1981, 1984, and 1986 and was named the NBA�s most valu�  able player for three consecutive years (1984-86). He retired in 1992 and  was head coach of the Indiana Pacers for the 1997-98 season.</p><p>bird flu or avian influenza viral respiratory disease, mainly of birds  including poultry and waterbirds but also transmissible to humans. Symp�  toms in humans include fever, sore throat, cough, headache, and muscle  aches. Severe infections can result in life-threatening complications such  as pneumonia and acute respiratory illness. The first known human cases  occurred in Hong Kong in 1997, resulting in six deaths. Deadly outbreaks  among poultry in several countries in eastern and central Asia between  2003 and mid-2005 were accompanied by more than 100 human cases,  about half of them fatal. The causative agents are virus subtypes related  to the human influenza type A viruses, the most virulent and contagious  being the H5N1 subtype. A specific protective vaccine for this virus  remains to be developed. Studies suggest that some antiviral drugs that  work against human influenza may be effective in treating bird flu in  humans.</p><p>bird-of-paradise Any of about 40 species (family Paradisaeidae) of  small to medium-size forest birds that are rivaled by only a few pheas�  ants and hummingbirds in colour and in the bizarre shape of the males�  plumage. Courting males perform mating rituals for hours on a perch or  in a cleared space on the forest floor. Birds-of-paradise are found in the  highlands of New Guinea and on nearby islands; some species are also  found in Australia. Among the most notable species are the plumebirds,  which are 12-18 in. (30^46 cm) long and have central tail feathers elon�  gated as wires or twisted ribbons.</p><p>bird-of-paradise or crane flower Ornamental plant (Strelitzia  reginae ) of the family Strelitziaceae. All five species of the genus Strel�  itzia are native to southern Africa. The large, showy Strelitzia flower has  two erect, pointed petals and five stamens. One main bract, shaped like a  boat, is green with red borders. It holds many long-stemmed orange and  bright blue flowers, each resembling the crest and beak of a crane, giv�  ing the plant its common names.</p><p>bird of prey Any member of the order Falconiformes (eagles, falcons,  hawks, and vultures) or Strigiformes (owls). Falconiforms are also called  raptors. They are active during the day, whereas owls are nocturnal. Con�  dors and eagles are among the largest and strongest of flying birds. All  birds of prey have a hook-tipped beak and sharp curved claws called tal�  ons. (Nonpredatory vultures have less-developed talons.) Despite the  similarities between owls and raptors, many authorities believe they are  not closely related but developed similar features because of their simi�  lar predatory lives.</p><p>bird stone Abstract stone carving by the prehistoric cultures of North  America. They resemble birds and are about 6 in. (15 cm) long. Many  were carved from black, brown, or dark green slate and polished with  sand or other abrasive materials.

The lists of bird observations compiled by members of local bird�  watching societies are often useful to scientists in determining dispersal,  habitat, and migration patterns of the various species. Bird-watching is  primarily a 20th-century phenomenon; before 1900 most students of birds  had to shoot them in order to identify them. Its popularity grew through  the publication of journals and books, in particular the field guides (begin�  ning in 1934) of Roger Tory Peterson.</p><p>bird's-foot trefoil Perennial, spreading, herbaceous legume {Lotus cor-  niculatus ) native to Europe and Asia but introduced to other regions. The  stem grows to about 2 ft (60 cm) long. Its leaves consist of three oval  leaflets, broadest near the tip. The yellow flowers (sometimes tinged with  red) grow in clusters of 5 to 10. Often used as forage for cattle, it is occa�  sionally a troublesome weed.</p><p>Birdseye, Clarence (b. Dec. 9, 1886, New York, N.Y., U.S.�d. Oct.  7, 1956, New York) U.S. businessman and inventor. He developed a  highly efficient process for freezing foods in small packages suitable for  retailing. He achieved rapid freezing by placing packaged food, includ�  ing fish, fruits, and vegetables, between two refrigerated metal plates.  Though his were not the first frozen foods, his process largely preserved  the original taste of the food. In 1929 his company was bought by Pos-  tum, Inc., which later became General Foods Corp.

It lies on the Chu River near the Kyrgyz Mountains on the Kazakhstan  border. In 1825 the Uzbek khanate of Kokand (see Qo'qon) established  a fortress on the site, which in 1862 was captured by the Russians. The  Russians mistakenly called it Pishpek. When the Kirgiz (Kyrgyz) Autono�  mous Soviet Socialist Republic was set up in 1926, the city became its  capital and was renamed Frunze for a Red Army leader who was born  there. It developed as an industrial city, especially in World War II (1939�  45) when heavy industries from western Russia were moved there.</p><p>bishop In some Christian churches, the chief pastor and overseer of a  diocese, an area containing several congregations. From the 4th century  ad until the Reformation, bishops held broad secular and religious pow�  ers, including the settling of disputes, ordination of clergy, and confirma�  tion of church members. Some Christian churches (notably the Anglican,  Roman Catholic, and Eastern Orthodox churches) continue the bishop�s  office and the doctrine of Apostolic succession. Others, including some  Lutheran and Methodist churches, retain bishops but not the principle of  apostolic succession; still others have abolished the office altogether.  Popes, cardinals, archbishops, patriarchs, and metropolitans are gradations  of bishops. In Roman Catholicism, the pope selects the bishop; in Angli�  canism, the dean and chapter of the cathedral of the diocese elect the  bishop; in Methodism a synod chooses the bishop.

In 1872  a military post was established to protect railway workers, and in 1873 it  was named for Otto von Bismarck in the hope of attracting German invest�  ment. With the discovery of gold in the nearby Black Hills, it became a  prospecting centre. In 1883 it was made the capital of Dakota Territory;  when the territory was divided into two states in 1889, Bismarck became  the capital of the northern state. Today it is the region�s business, cultural,  and financial centre.</p><p>Bismarck German battleship of World War II. The formidable 52,600-  ton (47,700-metric-ton) vessel was launched in 1939.

Two cruisers engaged it  near Iceland, and the Bismarck destroyed the Hood before escaping to the  open sea. Sighted 30 hours later, it was torpedoed and then bombarded  by battleships throughout the night. The King George V and the Rodney  crippled it in an hour-long attack, and it was finally sunk by torpedoes  from the cruiser Dorsetshire.</p><p>Bismarck, Otto (Eduard Leopold), prince von (b. April 1,1815,  Schonhausen, Altmark, Prussia�d. July 30, 1898, Friedrichsruh, near  Hamburg) Prussian statesman who founded the German Empire in 1871  and served as its chancellor for 19 years. Born into the Prussian landown�  ing elite, Bismarck studied law and was elected to the Prussian Diet in  1849. In 1851 he was appointed Prussian representative to the federal Diet  in Frankfurt. After serving as ambassador to Russia (1859-62) and France  (1862), he became prime minister and foreign minister of Prussia (1862�  71). When he took office, Prussia was widely considered the weakest of  the five European powers, but under his leadership Prussia won a war  against Denmark in 1864 (see Schleswig-Holstein Question), the Seven  Weeks' War (1866), and the Franco-Prussian War (1870-71). Through  these wars he achieved his goal of political unification of a Prussian-  dominated German Empire. Once the empire was established, he became  its chancellor. The �Iron Chancellor� skillfully preserved the peace in  Europe through alliances against France (see Three Emperors' League; Rein�  surance Treaty; Triple Alliance). Domestically, he introduced administrative  and economic reforms but sought to preserve the status quo, opposing the  Social Democratic Party and the Catholic church (see Kulturkampf). When  Bismarck left office in 1890, the map of Europe had been changed immea�  surably. However, the German Empire, his greatest achievement, survived  him by only 20 years because he had failed to create an internally uni�  fied people.</p><p>Bismarck Archipelago Island group, western Pacific Ocean.

Hard, brittle, and lustrous, it has a dis�  tinctive gray-white colour with a reddish tinge. It is often found free in  nature and also occurs in compounds and in mixed ores. Bismuth alloys  are used (because of their low melting points) in making metal castings,  special solders, automatic sprinkler heads, fuses, and many fire-detection  devices. Bismuth phosphomolybdate is a catalyst in the production of  acrylonitrile, an important raw material for fibres and plastics. Salts of  bismuth are used in making soothing agents for digestive disorders (espe�  cially bismuth subsalicylate), in treating skin infections and injuries, and  in lipstick, nail polish, and eye shadow, to which they impart a pearles-  cent quality.</p><p>bison Vbl-s 3 n, 'bl-z 3 n\ Either species (genus Bison ) of oxlike bovid with  a convex forehead and a pronounced  shoulder hump.

A mature bull  stands about 6.5 ft (2 m) at the shoul�  der and weighs more than 1,980 lb  (900 kg). Bison live in herds. The  American bison ( B. bison), com�  monly called buffalo, was abundant  over most of North America when  Europeans arrived. Uncontrolled  hunting drove it nearly to extinction  by 1900, but it has since recovered.

In 1941 it replaced Bolama as the country�s capital and has since devel�  oped as an excellent roadstead for large vessels.</p><p>bit in full binary digit In communication and information theory, a  unit of information equivalent to the result of a choice between only two  possible alternatives, such as 1 and 0 in the binary code generally used in  digital computers. It is also applied to a unit of memory corresponding to  the ability to store the result of a choice between two alternatives. A byte  consists of a string of eight consecutive bits and makes up the basic infor�  mation processing unit of a computer. Because a byte includes only an  amount of information equivalent to one letter or one symbol (e.g., a  comma), the processing and storage capacities of computer hardware are  usually given in kilobytes (1,024 bytes), megabytes (1,048,576 bytes), and  even gigabytes (about 1 billion bytes) and terabytes (1 trillion bytes).</p><p>bit-map Method by which a display space (such as a graphics image  file) is defined, including the colour of each of its pixels (or bits). In effect,  a bit-map is an array of binary data representing the values of pixels in  an image or display. A GIF is an example of a graphics image file that has  a bit-map. When the GIF is displayed on a computer monitor, the com�  puter reads the bit-map to determine which colours to use to �paint� the  screen. In a bit-mapped font, each character is defined as a pattern of dots  in a bit-map.</p><p>Bithynia \ba-'thin-e-a\ Ancient country, northwestern Anatolia.

A ligament hinges the shell's two halves (valves) open,  and the beating motion of cilia on the gills causes water to enter through the incur�  rent siphon. As water moves over the gills, oxygen diffuses into the blood, and food  particles become trapped in mucus and are moved to the mouth. A pair of adductor  muscles can hold the shell tightly closed. A fold of tissue (mantle) encloses the  body's organs and releases the material that forms the shell. A large muscular foot  allows the clam to creep and burrow. The circulatory system consists of a heart and  blood vessels, and kidneys remove wastes from the blood. Deoxygenated blood  and wastes are removed in the water that exits through the excurrent siphon.</p><p>� MERRIAM-WEBSTER INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>226 I Biwa &#x25BA; black-figure pottery</p><p>and by two sheets of tissue called the mantle.

Son of a music teacher, he gained admission to the Paris Conser�  vatoire at age 9, and at age 17 he wrote the precocious Symphony in C  Major (1855). Intent on success on the operatic stage, he produced The  Pearl Fishers (1863), La Jolie Fille de Perth (1866), and Djamileh (1871).  Disgusted with the frivolity of French light opera, he determined to reform  the genre of opera comique. In 1875 his masterpiece, Carmen , reached  the stage. Though its harsh realism repelled many, Carmen quickly won  international enthusiasm and was recognized as the supreme example of  opera comique.

Franklin Roosevelt appointed him to the Supreme Court of the United  States, where he helped reverse earlier court decisions against New Deal  legislation. In the 1960s he was prominent in the liberal majority that  struck down mandatory school prayer and guaranteed the availability of  legal counsel to suspected criminals. He became best known for his abso�  lutist belief in the Bill of Rights as a guarantee of civil liberties. His last  major opinion supported the right of the New York Times to publish the  Pentagon Papers (1971).</p><p>Black, Sir James (Whyte) (b. June 14, 1924, Uddingston, Scot.)

Based on the cultural politics of black nationalism, the  movement sought to create art forms capable of expressing the varieties  of black experience in the U.S. Leading theorists included Amiri Baraka,  Houston Baker (b. 1943), and Henry Louis Gates. Don L. Lee (b. 1942),  known as Haki R. Madhubuti after 1973, was one of its most popular  writers; other notable writers included Toni Morrison, Alice Walker, and  Ntozake Shange (b. 1948).

The canyon derives its name from  its black-stained, lichen-covered walls, which accentuate the gloom of the  chasm.</p><p>black codes Laws, enacted in the former Confederate states after the  American Civil War, that restricted the freedom of former slaves and were  designed to assure white supremacy. They originated in the slave codes,  which defined slaves as property. In some states these codes included  vagrancy laws that targeted unemployed blacks, apprentice laws that made  black orphans and dependents available for hire to whites, and commer�  cial laws that excluded blacks from certain trades and businesses and  restricted their ownership of property. Northern reaction to the laws  helped produce Radical Reconstruction and passage of the 14th and 15th  amendments to the Constitution, as well as creation of the Freedmen's  Bureau. Many provisions of the black codes were reenacted in the Jim Crow  laws and remained in force until the 1964 Civil Rights Act.</p><p>Black Death Fierce and widespread outbreak of plague, probably  bubonic and pneumonic, that ravaged Europe during the 14th century. The  epidemic originated in Asia and was transmitted to Europeans in 1347  when a Turkic army besieging a Genoese trading post in the Crimea cata�  pulted plague-infested corpses into the town.

It extends in a  fairly narrow strip about 100 mi (160  km) along the eastern bank of the  upper Rhine River, from the Neckar  River to the Swiss border. Its highest  peak is Feldberg, at 4,897 ft (1,493  m). Its name comes from its dark  interior, the higher parts being  thickly forested with fir and pine. It  is the source of the Neckar and  Danube rivers. The setting of many of  the Grimm brothers� fairy tales, it is  famed for the beauty and charm of  its villages and rolling hills. Winter  sports are prominent in the area, which also has many mineral springs  and watering places, including the spa town of Baden-Baden.</p><p>Black Friday Day (Sept. 24, 1869) when plunging gold prices precipi�  tated a U.S. stock-market panic.

Their name refers to the  dark appearance that their rounded hilltops and well-forested slopes  present at a distance. The Sioux Indians were guaranteed treaty rights to  the region in 1868; however, the discovery of gold in 1874 led to an influx  of white miners and to the Black Hills War (1876), including the Battle  of the Little Bighorn. Tourist attractions include the mining town of Dead-  wood, Mount Rushmore and Jewel Cave national monuments, Wind Cave  National Park, and Custer State Park, all in South Dakota, and Devils Tower  National Monument in Wyoming.</p><p>black hole Cosmic body with gravity (see gravitation) so intense that  nothing, not even light, can escape. It is suspected to form in the death  and collapse of a star that has retained at least three times the Sun�s mass.  Stars with less mass evolve into white dwarf stars or neutron stars. Details  of a black hole�s structure are calculated from Albert Einstein�s general  theory of relativity: a �singularity� of zero volume and infinite density pulls  in all matter and energy that comes within an event horizon, defined by  the Schwarzschild radius, around it. Black holes cannot be observed  directly because they are small and emit no light. However, their enor�  mous gravitational fields affect nearby matter, which is drawn in and emits  X rays as it collides at high speed outside the event horizon. Some black  holes may have nonstellar origins. Astronomers speculate that supermas-  sive black holes at the centres of quasars and many galaxies are the source  of energetic activity that is observed. Stephen W. Hawking theorized the  creation of numerous tiny black holes, possibly no more massive than an  asteroid, during the big bang. These primordial �mini black holes� lose  mass over time and disappear as a result of Hawking radiation. Although  black holes remain theoretical, the case for their existence is supported  by many observations of phenomena that match their predicted effects.</p><p>black humour Humour marked by the use of morbid, ironic, or gro�  tesquely comic episodes that ridicule human folly. The term came into  common use in the 1960s to describe the work of novelists such as Joseph  Heller, whose Catch-22 (1961) is an outstanding example; Kurt Vonnegut,  particularly in Slaughterhouse Five (1969); and Thomas Pynchon, in V  (1963) and Gravity�s Rainbow (1973).

The 16th-century historians Bartolome de Las Casas and Garcilaso  de la Vega documented the treatment of the Indians in New Spain (Mexico  and Guatemala) and Peru, respectively, and laid the foundation for the  legend. Though Spain may not actually have surpassed other colonial  powers in cruelty, the Spanish conquest clearly reduced the numbers of  indigenous peoples rapidly and caused them great suffering.</p><p>black letter or Gothic script or Old English script Style of alpha�  bet used in handwriting throughout Europe in the Middle Ages. It features  uniform vertical strokes that end on the baseline, angular lines instead of  smooth curves and circles, and the overlapping of convex forms. Black  letter and roman were the dominant letter shapes of medieval typography.  The only extant work known to have been printed by Johannes Gutenberg,  the 42-line Bible (1450s), was set in black-letter type. Roman type largely  superseded it in the Renaissance, though black letter persisted in Germany  well into the 20th century. Today black letter is often used for diplomas,  Christmas cards, and liturgical writings.</p><p>black market Trading in violation of publicly imposed regulations  such as rationing laws, laws against the sale of certain goods, and official  rates of exchange among currencies.

In the 1960s and �70s, Elijah  Muhammad and Malcolm X preached the ideal of black nationalism as an  alternative to assimilation into the predominantly white culture of the U.S.</p><p>Black Panther Party (for Self-Defense) U.S. African American  revolutionary party founded in 1966 by Huey Newton and Bobby Seale  (b. 1936) in Oakland, Calif. Its original purpose was to protect African  Americans from acts of police brutality. Eventually the Panthers devel�  oped into a Marxist revolutionary group that called for the arming of  African Americans, their exemption from the draft, the release of all Afri�  can American prisoners, and payment of compensation to African Ameri�  cans for centuries of exploitation by white Americans. By the late 1960s  it had more than 2,000 members, with chapters in several major cities; an  early spokesman was Eldridge Cleaver (1935-98). Conflicts with police  in the late 1960s and early �70s led to shoot-outs in California, New York,  and Chicago, one of which resulted in Newton�s imprisonment for the  murder of a police officer. Though some members of the party were guilty  of criminal acts, the entire group was subjected to violent attacks by police  and harassment by other government agencies, including the Federal  Bureau of Investigation. Police activities in dealing with the Panthers were  later the subject of congressional investigations. By the mid-1970s, hav�  ing lost many members and having fallen out of favour with African  American leaders, the party turned to providing social services in Afri�  can American neighbourhoods. By the early 1980s it had effectively dis�  banded.</p><p>black pepper or pepper Perennial, woody climbing vine ( Piper  nigrum ) of the family Piperaceae, native to India; also, the hotly pungent  spice made from its berries. One of the earliest spices known, pepper is  probably the most widely used spice in the world today. It early became  an important article of overland trade between India and Europe. The plant  is cultivated throughout Indonesia and has been introduced into tropical  areas elsewhere. It has broad, shiny leaves and dense, slender spikes of  small flowers. The small berrylike fruits are called peppercorns. See also  PEPPER.</p><p>black sand Accumulation of fragments of durable, usually dark, heavy  minerals (those with a density greater than that of quartz). These accu�  mulations are found in streambeds or on beaches where stream flow and  wave energy are sufficient to carry away low-density material but not the  heavy minerals. Thus, heavy minerals resistant to weathering and abra�  sion concentrate in these areas, though they may be only minor constitu�  ents of inland rocks. Placer mining of such deposits yields magnetite,  cassiterite, and zircon, as well as gold, platinum, and other rare metals.</p><p>Black Sea Sea between Europe and Asia. Bordered by Ukraine, Rus�  sia, Georgia, Turkey, Bulgaria, and Romania, it has a maximum depth of  7,250 ft (2,210 m). The Black Sea proper has an area of 163,000 sq mi  (422,000 sq km). It is connected with the Aegean Sea through the  Bosporus, the Sea of Marmara, and the Dardanelles, and with the Sea of  Azov by Kerch Strait. It receives many rivers, including the Danube, Dni�  ester, Bug, Dnieper, Kuban, Kizil, and Sakarya. The Crimean Peninsula (see  Crimea) extends into it from the north. Created when structural upheavals  in Asia Minor split off the Caspian basin from the Mediterranean Sea, the  Black Sea gradually became isolated; salinity is now less than half that  of the world�s oceans. Though long popular for its resorts, it has suffered  severe pollution in recent decades.</p><p>black snake Any of several species of all-black or nearly all-black  snakes. Australian black snakes are in the elapid genus Pseudeschis. The  black snake of Australian wetlands (P. porphyriacus) grows to an aver�  age length of 5 ft (1.5 m). If annoyed, it expands its neck, cobra fashion.  Its venom is rarely fatal. Other Australian black snakes are the mulga  snake (P. australis ) and the spotted black snake (P. guttatus). North Ameri�  can black snakes include two species in the family Colubridae: the black  racer and the pilot black snake ( Elaphe obsoleta).</p><p>Black Sox scandal U.S. baseball scandal, centring on the charge that  eight members of the Chicago White Sox had been bribed to lose the 1919  World Series to the Cincinnati Reds.

The first known play by an American  black was James Brown�s King Shotaway (1823). After the Civil War,  blacks began to perform in minstrel shows, and musicals written, produced,  and acted entirely by blacks appeared by c. 1900. The first real success  of a black dramatist was Angelina W. Grimke�s Rachel (1916). Theatre  flourished during the Harlem Renaissance of the 1920s and �30s, and by  1940 the American Negro Theater and the Negro Playwrights� Co. were  firmly established. After World War II black theatre grew more progres�  sive and militant, seeking to establish its own mythology, abolish racial  stereotypes, and integrate black playwrights into the mainstream. Its stron�  gest proponent, Amiri Baraka, established the Black Arts Repertory The�  atre in 1965. In the 1980s and �90s the African American playwrights  Charles Fuller and August Wilson won Pulitzer Prizes.</p><p>Black Warrior River Navigable river, western Alabama, U.S. Formed  by the confluence of the Locust and Mulberry forks in Jefferson county,  it flows southwest through coalfields to join the Tombigbee River near  Demopolis.

Together  they are referred to as Siksika, or Blackfoot, a name thought to have  derived from the discoloration of moccasins with ashes. They were among  the first Algonquians to move westward from timberland to open grass�  land and, later, among the first to acquire horses and firearms. They were  known as the strongest and most aggressive military power on the north�  western plains. At the height of their power, in the first half of the 19th  century, they held a vast territory extending from northern Saskatchewan  to southwestern Montana. Each group was subdivided into hunting bands  led by one or more chiefs. These bands wintered separately but came  together in summer to celebrate the sun dance. For three decades begin�  ning in 1806, the Blackfoot prevented white men from settling in their  territory. They signed their first treaty with the U.S. in 1855, after which  they were forced into farming and cattle raising. Some 10,000 Blackfoot  live in Canada, and more than 27,000 claimed sole Blackfoot descent in  the 2000 U.S. census, although only 15,000 U.S. Blackfoot are enrolled  members.

An advocate of mod�  eration in the Republican Party, he opposed the Radical Republicans led by  Roscoe Conkling. Elected to the U.S. Senate in 1876, he resigned his seat  in 1881 to become secretary of state. In this office he took the first steps  toward securing U.S. control of the eventual route of the Panama Canal.  As the Republican presidential candidate in 1884 he narrowly lost to  Grover Cleveland.

British politician who in 1997 became the country�s young�  est prime minister since 1812. Blair was a lawyer before winning election  to the House of Commons in 1983. Entering the shadow cabinet of the  Labour Party in 1988 at age 35, Blair urged the party to move to the politi�  cal centre and deemphasize its traditional advocacy of state control and  public ownership of certain sectors of the economy. He assumed leader�  ship of Labour in 1994 and revamped its platform. He led the party to  victories in the 1997, 2001, and 2005 elections. His government brokered  a peace agreement between unionists and republicans in Northern Ireland,  introduced devolved assemblies in Wales and Scotland, and carried out  reforms of Parliament. After the September 11 attacks on the U.S. in 2001,  Blair allied the United Kingdom with the U.S. and its president, George  W. Bush, in a global war against terrorism. In late 2002 Blair and Bush  accused the Iraqi government of Saddam Hussein of continuing to possess  and develop biological, chemical, and nuclear weapons in violation of UN  mandates. Despite deep divisions within his own party and strong public  opposition to a war with Iraq, Blair, with Bush, led an attack on Iraq that  toppled Hussein�s regime in March-April 2003.</p><p>Blais Vble\, Marie-Claire (b. Oct. 5, 1939, Quebec, Que., Can.)  French-Canadian novelist and poet. In two early, dreamlike novels, Mad  Shadows (1959) and Tete blanche (1960), she staked out her territory,  working-class people doomed to unrelieved sorrow and grinding poverty.  A Season in the Life of Emmanuel (1965) received the Prix Medicis and</p><p>was widely translated and discussed. Later works include The Manu�  scripts of Pauline Archange (1968, Governor General�s Award) and Deaf  to the City (1979, Governor General�s Award). She received the Gover�  nor General�s Award again in 1996 for Soifs (1995). She has also pub�  lished poetry collections and several plays.</p><p>Blake, Edward (b.

In 1867 he was elected  to the Canadian House of Commons. He served as premier of Ontario  (1871-72) and minister of justice (1875-77) in Alexander Mackenzie�s  cabinet, helping draft the constitution. He was leader of the Liberal Party  (1880-87). In 1890 he withdrew from Canadian politics and moved to  Ireland, where he served in the British House of Commons (1892-1907).</p><p>Blake, Eubie orig. James Hubert Blake (b. Feb. 7, 1883, Balti�  more, Md., U.S.�d. Feb. 12, 1983, Brooklyn, N.Y.) U.S. songwriter and  pianist. He played piano in cafes and brothels as a teenager, and in 1899  he composed his first ragtime song, �Sounds of Africa.� He and his part�  ner, lyricist and vocalist Noble Sissle (1889-1975), were among the first  African American performers to appear onstage without minstrel makeup.  Their show Shuffle Along (1921), which introduced Paul Robeson and  Josephine Baker, was among the first musicals written, produced, and  directed by African Americans. In 1925 Blake cowrote the score to Black�  birds of 1930. He achieved his greatest fame when the musical Eubie  opened on Broadway (1978). He gave his last concert in 1982.</p><p>Blake, William (b. Nov. 28, 1757, London, Eng.�d. Aug. 12, 1827,  London) English poet, painter,  engraver, and visionary. Though he  did not attend school, he was trained  as an engraver at the Royal Academy  and opened a print shop in London  in 1784. He developed an innovative  technique for producing coloured  engravings and began producing his  own illustrated books of poetry with  his �illuminated printing,� including  Songs of Innocence (1789), The  Marriage of Heaven and Hell  (1793), and Songs of Experience  (1794). Jerusalem (1804-20), his  third major epic treating the fall and  redemption of humanity, is his most  richly decorated book. His other  major works include The Four Zoas  (1795-1804) and Milton (1804-08).</p><p>A late series of 22 watercolours  inspired by the Book of Job includes  some of his best-known pictures. He  was called mad because he was  single-minded and unworldly; he  lived on the edge of poverty and died  in neglect. His books form one of the most strikingly original and inde�  pendent bodies of work in the Western cultural tradition. Ignored by the  public of his day, he is now regarded as one of the earliest and greatest  figures of Romanticism.</p><p>Blakelock, Ralph (b. Oct. 15, 1847, New York, N.Y., U.S.�d. Aug.  9, 1919, near Elizabethtown, N.Y.) U.S. painter. A self-taught artist, he  developed a highly original and subjective style of landscape painting,  characterized by luminous impasto images of moonlit scenes with noc�  turnal lighting and strangely dappled trees and foliage. Neglected by the  public and constantly under the strain of poverty, he suffered a breakdown  in 1899, ceased to paint, and spent the rest of his life in an asylum. Dur�  ing his confinement he achieved some fame, and forgeries of his work  became common as his popularity rose.</p><p>Blakeslee, Albert Francis (b. Nov. 9, 1874, Geneseo, N.Y., U.S.�d.

He worked with Fletcher Henderson�s big band before  joining Billy Eckstine�s forward-looking ensemble (1944-47). Blakey�s  prodigious technique and thunderous attack assured his role as one of the  principal drum stylists in modern jazz. With Horace Silver, Blakey formed  the Jazz Messengers in 1954, and the group, with its aggressive blues-  inflected approach, became the archetypal hard-bop unit (see bebop).</p><p>Blalock Vbla-JakV Alfred (b. April 5, 1899, Culloden, Ga., U.S.�d.  Sept. 15, 1964, Baltimore, Md.) U.S. surgeon. He received an M.D. from  Johns Hopkins University. His research, showing that traumatic and hem�  orrhagic shock resulted from loss of blood volume, led to volume-  replacement treatment, which saved countless lives during World War II.  He is remembered for his development, with Helen Brooke Taussig, of a  surgical treatment for heart malformations in newborns. In 1944 he per�  formed the first subclavian-pulmonary artery anastomosis operation,  which corrected the birth defect.</p><p>His balloon flights in other European countries and in the U.S. in  1793 spurred an interest in ballooning.

April 16, 1864, Boston, Mass.) U.S. inventor. In 1818 he  invented a lathe capable of turning irregular shapes, such as a gunstock.  It duplicated the form of a pattern object by transmitting to the cutting  tool the motion of a friction wheel rolling over the pattern. His invention  was an essential step in the development of mass production techniques.  He produced several successful designs of shallow-draft steamboats, and  in 1849 he invented machinery for bending wood into complex shapes  such as plow handles and ship�s frames.</p><p>Blanda, George (Frederick) (b.

As  a professional quarterback and kicker, he played for the Chicago Bears  (1949-58), Houston Oilers (1960-66), and Oakland Raiders (1967-76),  setting still-standing records for most seasons played (26), most games  played (340), and most points after touchdowns (943). His record for most  field goals (335) was broken in 1983.</p><p>blank verse Unrhymed verse, specifically unrhymed iambic pentam�  eter, the preeminent dramatic and narrative verse form in English. It is  also the standard form for dramatic verse in Italian and German. Adapted  from Greek and Latin sources, it was introduced in Italy, then in England,  where in the 16th century William Shakespeare transformed blank verse into  a vehicle for the greatest English dramatic poetry, and its potential for  grandeur was confirmed with John Milton�s Paradise Lost (1667).</p><p>Blanqui \bla n -'ke\, (Louis-) Auguste (b.

A legendary martyr-figure of French radicalism, Blanqui believed that  there could be no socialist transformation of society without a temporary  dictatorship that would eradicate the old order. His activities, including  the formation of various secret societies, caused him to be imprisoned  various times for a total of more than 33 years. His disciples, the Blan-  quists, played an important role in the history of the workers� movement  even after his death.</p><p>blanquillo See tilefish</p><p>Blanton, Jimmy orig. James Blanton (b.

Blanton�s buoyant rhythmic approach and harmonic subtlety provided a  supple, relaxed sense of swing for the band. His unprecedented dexterity,  tone, and intonation enabled him to execute a melodic conception of the  role of the bass in jazz, demonstrated on recordings made with Ellington  such as �Jack the Bear� and �Pitter Panther Patter.� His revolutionary  technique changed jazz bass playing and became the major influence on  subsequent bassists. He died of tuberculosis.</p><p>Blantyre \blan-'tlr\ City (pop., 2003 est.: 646,235), southern Malawi.  It is the largest city in Malawi and the seat of the country�s judiciary.

After serving in  the U.S. Army during World War II, he returned to New York, where in  1959 he became the head designer of Maurice Rentner, Ltd. Building upon  the innovations of European designers such as Coco Chanel, Blass made  clothes that allowed women a chic, modern sense of ease and comfort.  His work became popular among New York high-society women. In 1970  Blass became owner of Rentner, which he renamed after himself. He was  a pioneer in employing the business strategy of licensing his designs and  name to a huge array of fashion accessories. In 1999 he sold his company,  which continued as Bill Blass Ltd., and he retired the following year.</p><p>blast furnace Vertical shaft furnace that produces liquid metals by the  reaction of air introduced under pressure into the bottom of the furnace  with a mixture of metallic ore, fuel, and flux fed into the top. Blast fur�  naces are used to produce pig iron from iron ore for subsequent process�  ing into steel; they are also employed in processing lead, copper, and other  metals. The current of pressurized air maintains rapid combustion. Blast  furnaces were used in China as early as 200 bc, and appeared in Europe  in the 13th century, replacing the bloomery process. Modem blast furnaces  are 70-120 ft (20-35 m) high, have 20�45-ft (6-14-m) health diameters,  use coke fuel, and can produce 1,000-10,000 tons (900-9,000 metric tons)  of pig iron daily.

Usually the shoots and other young,  rapidly growing tissues of a plant are attacked. Most blights are caused by  bacteria or fungi (see fungus); some result from drought. Fungal and bac�  terial blights are most likely under cool, moist conditions. Most economi�  cally important plants are susceptible to one or more blights. Measures  taken to fight blight include destroying the infected plant parts; using  disease-free seed or stock and resistant varieties; rotating crops (see crop  rotation); pruning and spacing plants for better air circulation; controlling  pests that carry the fungus from plant to plant; avoiding overhead watering  and working among wet plants; and, where needed, applying fungicides or  antibiotics. Maintaining sanitary conditions is the most important measure  for stopping the spread of the infestation.

Other  cave-dwelling fishes tending toward blindness are found in Cuba, Mexi�  co�s Yucatan, South America, and Africa.</p><p>blindness Inability to see with one or both eyes. Transient blindness  (blackout) can result from vertical acceleration causing high gravitational  forces, glomerulonephritis (a kidney disease), or a clot in a blood vessel  of the eye. Continuing blindness may arise from injuries or diseases of  the eye (e.g., cataract, glaucoma), including the retina, the optic nerve, or  the brain�s visual centres. Many infectious, noninfectious, and parasitic  systemic diseases can cause blindness. Sexually transmitted diseases and  rubella in pregnant women can cause blindness in their infants.

A small  gap opens between them and becomes filled with fluid. This type gener�  ally heals spontaneously, sometimes leaving a thickened callus. Blisters  that occur as symptoms of contact dermatitis, viral infection, or autoimmune  disease can appear anywhere on the body and may leave scars.</p><p>blister beetle Any of approximately 2,000 species of beetles (family  Meloidae) that secrete an irritating  substance, cantharidin, which is used  medically as a topical skin irritant to  remove warts. In the past, canthari�  din was often used to induce blisters,  a common remedy for many ail�  ments, and the dried remains of  Spanish fly ( Lytta vesicatoria ) were  a major ingredient in so-called love  potions. Adult blister beetles, which  are often brightly coloured, range  between 0.1 and 0.8 in. (3-20 mm)  in length. Blister beetles are both helpful and harmful to humans; the lar�  vae eat grasshopper eggs, but the adults destroy crops.</p><p>blister rust Any of several diseases of pines, caused by rust fungi (see  fungus) of the genus Cronartium. Blister rust affects sapwood (see wood)  and inner bark and produces external blisters from which additional spores  of the fungus are released and resin oozes, forming characteristic hard�  ened masses on the trunk. It affects pines of all ages and sizes, retarding  growth and weakening stems as it spreads along the trunk, sometimes  killing the tree; young trees are killed more quickly than older ones. Mea�  sures taken to fight blister rust include growing resistant varieties, destroy�  ing nearby alternative host plants, observing strict sanitation measures,  and spraying with fungicides.</p><p>blitzkrieg Vblits-,kreg\ (German: �lightning war�) Military tactic used  by Germany in World War II, designed to create psychological shock and  resultant disorganization in enemy forces through the use of surprise,  speed, and superiority in materiel or firepower. The Germans tested the  blitzkrieg during the Spanish Civil War in 1938 and against Poland in 1939,  and used it in the successful invasions of Belgium, the Netherlands, and  France in 1940. The German blitzkrieg coordinated land and air attacks�  using tanks, dive-bombers, and motorized artillery�to paralyze the  enemy principally by disabling its communications and coordination  capacities.</p><p>Blitzstein Vblit-.stlnV Marc (b. March 2, 1905, Philadelphia, Pa.,  U.S.�d. Jan. 22, 1964, Fort-de-France, Martinique) U.S. composer. He  studied at the Curtis Institute, then with the conductor Nadia Boulanger  in Paris and the composer Arnold Schoenberg in Berlin. His best-known  works were for the theatre: The Cradle Will Rock (1937), the circum�  stances of whose production by Orson Welles and John Houseman became  legendary; the opera Regina (1949); and his English adaptation of Bertolt  Brecht and Kurt Weill�s The Threepenny Opera (1952), which became a  Broadway hit. He was working on a Metropolitan Opera commission for  an opera about the Sacco-Vanzetti case when he was murdered.</p><p>Blobel, Gunter (b. May 21, 1936, Waltersdorf, Silesia, Ger.) U.S. cel�  lular and molecular biologist. He earned his M.D. from Eberhard-Karl  University and his Ph.D. from the University of Wisconsin. Working in  collaboration with other research groups, Blobel showed that each pro�  tein carries a signal sequence that directs it to the proper location inside  the cell. He also concluded that proteins enter organelles through a pore�  like channel that opens in the organelle�s outer membrane when the cor�  rect protein arrives at the organelle. For his work, Blobel was awarded a  Nobel Prize in 1999. His research shed light on such hereditary diseases  as cystic fibrosis and provided the basis for bioengineered drugs, includ�  ing INSULIN.</p><p>Bloc National Vblok-nas-yo-'naU Right-wing coalition that controlled  the French government from 1919 to 1924. On a wave of nationalist sen�  timent at the end of World War I, the Bloc gained about 75% of the seats  in the French Chamber of Deputies in the 1919 elections. The government  tried to ensure French security against Germany through a strict enforce�  ment of the Treaty of Versailles.

July 15,  1959, Portland, Ore., U.S.) Swiss-born U.S. composer. He conducted and  lectured at the Geneva Conservatory before moving in 1916 to the U.S.,  where he served as director of the San Francisco Conservatory (1925-30)  and taught at the University of California, Berkeley (1942-52). He  worked in tonal, atonal, and serialist idioms (see also tonality; atonality;  serialism); his works, many of them inspired by Jewish themes, include the  opera Macbeth (1910), Schelomo for cello and orchestra (1916), the large  choral works America (1926) and Avodath hakodesh (1933), and a violin  concerto (1938).</p><p>Bloch Vblak\, Felix (b. Oct. 23,1905, Zurich, Switz.�d. Sept. 10, 1983,  Zurich) Swiss-born U.S. physicist. He emigrated to the U.S. in 1933 and  taught at Stanford University (1934-71). He worked on atomic energy at  Los Alamos and on radar countermeasures at Harvard University during  World War II. In 1954 he became the first director general of CERN. For  developing the nuclear magnetic resonance method of measuring the mag�  netic fields of atomic nuclei, he shared with Edward Purcell (1912�97)  the 1952 Nobel Prize for Physics.</p><p>Bloch Vblok\, Marc (Leopold Benjamin) (b. July 6, 1886, Lyon,  France�d. June 16, 1944, near Lyon) French historian. He served in the  French infantry in World War I. From 1919 he taught medieval history at  the University of Strasbourg, where he cofounded the important periodi�  cal Annales d�histoire economique et sociale. He taught economic history  at the Sorbonne from 1936. During World War II he joined the French  Resistance and was captured and killed by the Germans. Among his major  works are The Royal Touch (1924), French Rural History (1931), and  Feudal Society (1939). As the founder of the Annales school of histori�  ography, with its wide-ranging, interdisciplinary approach, Bloch exerted  a huge influence on the study of history.</p><p>block and tackle Combination of pulleys with a rope or cable, com�  monly used to augment pulling force. Two or more of the pulleys are  attached to a fixed block, and the remaining pulleys are free to move as well  as rotate. A block and tackle can be used to lift heavy weights or to exert  large forces in any direction. Higher force ratios may be obtained by the use  of more pulleys, but this advantage may be offset by increased friction.</p><p>Block Island Island, Rhode Island, U.S. It lies at the eastern entrance  to Long Island Sound, 9 mi (15 km) southwest of Point Judith, R.I. It has  an area of about 11 sq mi (29 sq km) and is coextensive with the town of  New Shoreham (pop., 2000: 1,010). Called Manisses by its original Indian  inhabitants. Block Island (named for the Dutch explorer Adriaen Block)  received its first European settlers in 1661 and was admitted to the colony  of Rhode Island in 1664. Once dependent on fishing and farming, it is  now primarily a resort.</p><p>block mill Earliest mechanized factory for mass production. It was con�  ceived by Samuel Bentham, with machinery designed by Marc Brunel and  built by Henry Maudslay, and built at England�s Portsmouth naval dock�  yard. By 1805 it was producing 130,000 pulley blocks per year. It  remained in production for over 100 years. See also American System of  MANUFACTURE.</p><p>blockade Act of war whereby one party blocks entry to or departure  from an enemy area, often a coast. Blockades are regulated by interna�  tional law and custom, which require advance warning to neutral states  and impartial application. Penalties for breach of blockade are seizure of  ship and cargo and their possible condemnation as lawful prizes. Neutral  ships may not be destroyed for blockade running.</p><p>Bloemfontein Vblum-.fan-.tanN City (pop., 2005 est.: 379,000), judi�  cial capital of the Republic of South Africa. It is also the capital of Free  State province. Founded in 1846 as a fort, it became the seat of the  British-administered Orange River Sovereignty (1848-54) and later that  of Orange Free State, an independent Boer republic formed in 1854. The  failure of the Bloemfontein Conference (1899) resulted in the outbreak of  the South African War. In the 20th century the city became a geographi�  cal transportation hub. Bloemfontein became part of the Mangaung Local  Municipality in 2000. See also Pretoria; Cape Town.</p><p>Blok, Aleksandr (Aleksandrovich) (b. Nov. 28, 1880, St. Peters�  burg, Russia�d. Aug. 7, 1921, Petrograd [St. Petersburg]) Russian poet  and dramatist. He was the principal representative of Russian Symbolism</p><p>(see Symbolist movement). He later rejected what he termed their sterile  bourgeois intellectualism and embraced the Bolshevik movement as  essential for the redemption of the Russian people. Influenced by early  19th-century Romantic poetry, he wrote musical verse in which sound was  paramount. His preeminent work of impressionistic verse was the enig�  matic ballad The Twelve (1918), which united the Russian Revolution and  Christianity in an apocalyptic vision. In the era of postrevolutionary hard�  ship he declined into mental and physical illness, possibly brought on by  venereal disease, and died at 40.</p><p>Blondin \blo n -'da n ,\ English \'blan-den\ orig. Jean-Francois Grav-  elet (b. Feb. 28, 1824 , Hesdin, Fr.�d. Feb. 22, 1897, Little Ealing, near  London, Eng.) French tightrope walker. After training as an acrobat, he  achieved fame, first in 1859, with his many crossings of Niagara Falls on  a tightrope 1,100 ft (335 m) long, 160 ft (48 m) above the water. Each  time he used a different theatrical variation: blindfolded, in a sack, trun�  dling a wheelbarrow, on stilts, carrying a man on his back, and sitting  down midway to cook an omelette. He gave his last performance in 1896.</p><p>blood Circulatory fluid (see circulation) in multicellular animals. In  many species it also carries hormones and disease-fighting substances.  Blood picks up oxygen from the lungs and nutrients from the gastrointes�  tinal tract and carries them to cells throughout the body for metabolism. It  picks up carbon dioxide and other wastes from those cells and transports  them to the lungs and excretory organs. Blood composition varies among  species. Mammalian blood consists of plasma, red and white cells (eryth�  rocytes and leukocytes), and platelets (thrombocytes). Blood disorders  include polycythemia (abnormal increase in the number of circulating red  blood cells), anemia, leukemia, and hemophilia. See also ABO blood-group  system; blood analysis; blood bank; blood pressure; blood transfusion; blood  typing; Rh blood-group system.</p><p>blood analysis Laboratory examination of the physical and chemical  properties and components of a sample of blood. Analysis includes num�  ber of red and white blood cells (erythrocytes and leukocytes); red cell vol�  ume, sedimentation (settling) rate, and hemoglobin concentration; blood  typing; cell shape and structure; hemoglobin and other protein structure;  enzyme activity; and chemistry. Special tests detect substances character�  istic of specific infections.</p><p>blood bank Organization that collects, stores, processes, and supplies  blood. Most blood donations are separated into components, which can  be frozen and stored longer than whole blood and used by multiple  patients. In hemapheresis, large amounts of one component can be sepa�  rated from a single donor�s blood and the rest returned to the donor. Before  World War I, a physician had to find a compatible donor and give an  immediate blood transfusion. Safe storage of blood and its components  made possible innovations such as heart-lung machines.</p><p>blood poisoning See septicemia</p><p>blood pressure Force originating when the heart�s pumping pushes  the blood against the walls of the blood vessels. Their stretching and con�  traction help maintain blood flow. Usually measured over an arm or leg  artery in humans, blood pressure is expressed as two numbers; normal  adult blood pressure is about 120/80 mm of mercury. The higher number  (systolic) is measured when the heart�s ventricles contract and the lower  (diastolic) when they relax. See also hypertension, hypotension.</p><p>blood transfusion Transfer of blood taken from one person into the  circulation of another to restore blood volume, increase hemoglobin lev�  els, or combat shock. Once the blood-group antigens and antibodies (see  ABO blood-group system, Rh blood-group system) were discovered, BLOOD  typing of donors and recipients rendered transfusion safe. In exchange  transfusion, all or most of the blood is removed and replaced with anoth�  er�s blood. Undesirable reactions to transfusion are not uncommon.</p><p>blood typing Classification of blood by inherited antigens associated  with erythrocytes (red blood cells). The ABO blood-group system and Rh  blood-group system are among those most commonly considered. Without  identification of these factors, blood transfusion from an incompatible  donor may result in destruction of red cells or coagulation. Blood typing  also helps identify disorders such as erythroblastosis fetalis.</p><p>bloodhound Breed of dog superior to any other in scenting ability, the  foundation breed of most scent-hunting hound breeds.

A large, strong dog, the bloodhound stands 23-27  in. (58-69 cm) and weighs 80-110 lb (35-50 kg). It has short hair and  long ears, with loose skin that falls into folds and wrinkles around the  head and neck. The coat is black-and-tan, red-brown and tan, or tawny.</p><p>Bloodless Revolution See Glorious Revolution</p><p>bloodroot Plant ( Sanguinaria canadensis ) of the poppy family, native  throughout eastern and midwestern  North America, growing mainly in  deciduous woodlands and blooming  in early spring. The white, cup�  shaped flower with bright yellow sta�  mens in the centre is borne on a  reddish stalk. Large, veiny, half-  opened leaves on red stalks enfold  the flower stem and, after the flower  has bloomed, open into multilobed,  round, blue-green leaves. The  orange-red sap, once used by Ameri�  can Indians for dye, is found in the  rhizomes, as is the medical alkaloid  sanguinarine. The species, particu�  larly the variety S. canadensis �Mul�  tiplex,� which has showy double flowers, is an interesting plant for the  wild garden.</p><p>Bloody Sunday (1905) Massacre of peaceful demonstrators in Saint  Petersburg, marking the beginning of the Russian Revolution of 1905. The  priest Georgy Gapon (1870-1906), hoping to present workers� request for  reforms directly to Nicholas II, arranged a peaceful march toward the  Winter Palace. Police fired on the demonstrators, killing more than 100  and wounding several hundred more. The massacre was followed by  strikes in other cities, peasant uprisings, and mutinies in the armed forces.  The term �Bloody Sunday� was also used to describe the murder in Dub�  lin, Ireland (Nov. 21, 1920), of 11 Englishmen suspected of being intel�  ligence agents, by the Irish Republican Army; the Black and Tans took  revenge and attacked spectators at a football (soccer) match, killing 12  and wounding 60. The term was used again in Londonderry (Derry) when  on Jan. 30, 1972, 3 participants in a civil rights march were killed by  British soldiers, who allegedly had been fired on by the marchers.</p><p>Bloom, Harold (b. July 11, 1930, New York, N.Y., U.S.) U.S. literary  critic. Bloom studied at Cornell and Yale universities and taught at Yale  from 1955. In The Anxiety of Influence (1973) and A Map of Misreading  (1975) he suggested that poetry results from poets deliberately misread�  ing the works that both influence and threaten them. In The Book of J  (1990) he speculated that the earliest known biblical texts were written  by a woman with principally literary intentions. His best-selling The West�  ern Canon (1994) identifies 26 canonical Western writers and argues  against the politicization of literary study.</p><p>Bloomer, Amelia orig. Amelia Jenks (b. May 27, 1818, Homer,  N.Y., U.S.�d. Dec. 30, 1894, Council Bluffs, Iowa) U.S. reformer. In  1840 she married Dexter Bloomer, a Quaker newspaper editor. She wrote  articles on education, unjust marriage laws, and women�s suffrage and  published the biweekly Lily (1849-54). Among her interests was dress  reform, and the full trousers that she wore came to be known as bloomers.  Her costume generated considerable publicity and helped to attract large  crowds to her lectures in New York City, where she often shared the plat�  form with Susan B. Anthony and the Rev. Antoinette L. Brown.</p><p>bloomery process Process for iron smelting. In ancient times, smelt�  ing involved creating a bed of red-hot charcoal in a furnace to which iron  ore mixed with more charcoal was added. The ore was chemically reduced  (see oxidation-reduction), but, because primitive furnaces could not reach  the melting temperature of iron, the product was a spongy mass of pasty  globules of metal intermingled with a semiliquid slag. This hardly usable  product, known as a bloom, may have weighed up to 10 lbs (5 kg).  Repeated reheating and hot hammering eliminated much of the slag, cre�  ating wrought iron, a much better product. By the 15th century, many  bloomeries used low shaft furnaces with waterpower to drive the bellows,  and the bloom, which might weigh over 200 lbs (100 kg), was extracted  through the top of the shaft. The final version of this kind of bloomery  hearth survived in Spain until the 19th century. Another design, the high  bloomery furnace, had a taller shaft and evolved into the Stiickofen, which  produced blooms so large they had to be removed through a front opening.</p><p>Bloomfield, Leonard (b. April 1, 1887, Chicago, Ill., U.S.�d. April  18, 1949, New Haven, Conn.) U.S. linguist. He began his career as a phi�  lologist trained in Indo-European, especially Germanic languages. He  taught Germanic philology at the University of Chicago (1927^10) and  linguistics at Yale (1940-49). In Language (1933), one of the clearest  20th-century presentations of linguistics, he advocated the study of lin�  guistic phenomena in isolation from their nonlinguistic environment and  emphasized the need for empirical description. His thinking was influ�  enced by his work on non-Indo-European languages, particularly the  Algonquian family; The Menomini Language (1962) is a paragon of lin�  guistic description and American Indian linguistic scholarship.</p><p>Bloomsbury group A coterie of English writers, philosophers, and  artists. The name was a reference to the Bloomsbury district of London,  where between about 1907 and 1930 the group frequently met to discuss  aesthetic and philosophical questions. Among the group were E.M. For�  ster, Lytton Strachey, Clive Bell, the painters Vanessa Bell (1879-1961) and  Duncan Grant (1885-1978), John Maynard Keynes, the Fabian writer  Leonard Woolf (1880-1969), and Virginia Woolf.</p><p>Blount \'bl3nt\, William (b.

He served in the  American Revolution before being elected to six terms in the North Caro�  lina legislature. He was a delegate to the Constitutional Convention. As  the first governor of lands ceded to the U.S. by North Carolina, he worked  to secure statehood for what would become Tennessee. In 1796 he became  one of Tennessee�s first two senators, but he was expelled from the Sen�  ate in 1797 on charges of plotting to help the British gain control of Span�  ish Florida and Louisiana.</p><p>Blow, John (baptized Feb. 23, 1649, Newark-on-Trent, Nottingham�  shire, Eng.�d. Oct. 1, 1708, Westminster, London) British composer,  organist, and teacher. He was appointed organist at Westminster Abbey  in 1668; in 1774 he became master of the children at the Chapel Royal,  and he later held various equally prominent posts, in which he influenced  many students, including composer Henry Purcell. Of the many religious  and secular ceremonial works he wrote in his official capacities, about 12  services and more than 100 anthems survive. His court masque Venus and  Adonis { 1685) represents a landmark in the development of English opera.</p><p>blowfish See puffer</p><p>blowfly Any member of the dipteran family Calliphoridae, including the  screwworm and the bluebottle, greenbottle, and cluster flies. Metallic blue,  green, or bronze, and noisy in flight, blowflies resemble the housefly in  size and habits. The larvae usually feed on decaying flesh and sometimes  infest open wounds. They may help prevent infection by cleaning away  dead flesh, but may also destroy healthy tissue. Blowflies were once used  to treat gangrene and a human bone disease and were used in World War  I to clean soldiers� wounds. Some species seriously hurt or kill livestock  by massive infestation or by carrying diseases such as anthrax, dysentery,  and jaundice.</p><p>blowgun Long, narrow pipe through which darts or other projectiles  are blown. Primarily a hunting weapon, it is rarely used in warfare. It has  been used by aboriginal peoples in Malaysia and elsewhere in South Asia,  southern India and Sri Lanka, Madagascar, northwestern South America,  and Central America. Blowguns vary in length from 18 in. to more than  23 ft (45 cm to 7 m) and are often made of cane or bamboo. Darts are  usually made of palm-leaf midribs or wood or bamboo splinters 1.5-40  in. (4-100 cm). The dart must fit the tube snugly, so that a puff of human  breath will cause it to fly from the tube. To be effective against quarry  larger than small birds, blowgun darts require poison.</p><p>blowing engine Machine for pumping air into a furnace. Bellows  driven by a waterwheel were the earliest form of blowing engine, later  replaced by reciprocating pumps driven by steam or gas engines and by  turbo-blowers.

It lives in schools and is a voracious predator of smaller animals, espe�  cially other fishes. It is slender and has a forked tail and a large mouth  with strong, pointed teeth. It is blue or greenish and grows to a length of  about 4 ft (1.2 m) and a weight of 25 lbs (11.5 kg).</p><p>bluegill Popular game fish ( Lepomis macrochirus) and one of the best-  known sunfishes throughout its original range, the freshwater habitats of  the central and southern U.S. It has been introduced throughout the west�  ern U.S. and in other parts of the world. Bluegills are usually bluish or  greenish and have a characteristic dark flap at the rear of the gill cover.  Among the smallest of the food and game fishes, they normally are only  6-9 in. (15-23 cm) long and weigh less than 0.5 lbs (0.25 kg). Bluegills  are known as highly spirited fighters on the end of a fishing line.</p><p>bluegrass Any of many slender annual and perennial lawn, pasture,  and forage GRASSes of the genus Poa, in the family Poaceae, or Gramineae.  About 250 species are found in temperate and cool climates, more than  50 in the U.S. Most have small spikelets lacking bristles and arranged in  open clusters. The narrow leaf blades have boat-shaped tips. With its  blue-green leaves, Kentucky bluegrass (P. pratensis), the best-known U.S.  species, is a popular lawn and pasture grass in the northern states and is  common in open areas and along roadsides. Texas bluegrass (P. arach-  nifera), mutton grass (P. fendleriana), and plains bluegrass (P arida ) are  important western forage grasses. Annual bluegrass (P. annua), a small,  light green species, is considered a pest in lawns.</p><p>bluegrass In music, a country-music style that emerged after World War  II. It is a direct descendant of the string-band music played by groups  such as the Carter Family. Bluegrass is distinguished from its predecessors  by its more syncopated rhythm, its high-pitched tenor (lead) vocals, its  tight harmonies, its driving rhythms, and a strong influence of jazz and  blues. A very prominent place is given to the banjo, always played in the  unique three-finger style developed by Earl Scruggs (see Lester Flatt).  Mandolin and fiddle are generally featured, and traditional square-dance  tunes, religious songs, and ballads furnish much of the repertory. Blue�  grass was originated by and got its name from Bill Monroe and his Blue  Grass Boys. From the late 1940s on, it continued to grow in popularity;  from the 1970s an influx of younger musicians brought some influence  from rock music.</p><p>Bluegrass region Area of central Kentucky, U.S. The region contains  Kentucky�s best agricultural land and thus became the first area to be  settled. It became known for its abundant bluegrass and became famous  for breeding fine horses; the calcium-rich soil imparts its minerals to the  grass and thence into the horses� bones.</p><p>blues Secular musical form incorporating a repeating harmonic struc�  ture with melodic emphasis on the flatted or �blue� third and seventh notes  of the scale. The specific origins of the blues are not known, but elements  of the music of former slaves include the call-and-response pattern and  syncopated rhythms of spirituals and work songs. The codification of the  structure of the blues occurred in the early 20th century, most commonly  as a 12-bar phrase using the chords of the first, fourth, and fifth degrees  of the major scale. Its origins as a primarily vocal form induced instru�  mental performers to imitate the human voice with �bent� notes. Lyric  stanzas are usually in three lines, the words of the second generally repeat�  ing those of the first. The elaboration of the rural blues from Texas and  the Mississippi delta established both lyric and instrumental traditions,  often featuring speech-like inflection and guitar accompaniment. The  bandleader W.C. Handy�s compositions brought blues elements to the  popular music of the first decades of the century. The first blues record�  ings, in the early 1920s, featured singers such as Ma Rainey and Bessie  Smith using jazz accompanists; their style would become known as clas�  sic blues. The highly personal interpretations and improvisation of the  blues, combined with elements of its structure and inflection, served as  the foundation for jazz, rhythm and blues, and rock music.</p><p>Bluestocking In mid-18th-century England, any of a group of women  who met to discuss literature. Attempting to replace the playing of cards  and such social activities with more intellectual pursuits, they held �con�  versations� to which they invited men of letters and members of the aris�  tocracy with literary interests. The term probably originated when Mrs.  Elizabeth Vesey invited the learned Benjamin Stillingfleet to one of her  parties; he declined, saying he lacked appropriate dress, until she told him  to come �in his blue stockings��the ordinary worsted stockings he was</p><p>wearing at the time. The word bluestocking came to be applied derisively  to a woman who affects literary or learned interests.</p><p>Bluford Vblii-fordX, Guion S(tewart), Jr. (b.

He made a name as a  brilliant literary and drama critic, then entered politics in the French  Socialist Party. As a member of the Chamber of Deputies (1919-28, 1929-  40), he became a leader of the Socialists from 1921. The chief architect  of an electoral alliance of the left, he became the first Socialist (and the  first Jewish) premier of France as head of the Popular Front government  (1936-37). He introduced such reforms as the 40-hour workweek and  collective bargaining and nationalized the chief war industries and the  Bank of France. Arrested by the Vichy government in 1940, he was  imprisoned until 1945. In the postwar years he was one of France�s lead�  ing veteran statesmen.</p><p>Blumberg Vbbm-borgX, Baruch S(amuel) (b.

From 1937 Blunt had  a brilliant career as an art historian, publishing scores of scholarly works  that largely established art history in Britain. In World War II he served  in British military intelligence and also gave secret information to the  Soviets. In 1945 he was appointed surveyor of the king�s (later queen�s)  pictures, and in 1947 he became director of the prestigious Courtauld  Institute. He ceased active intelligence work but in 1951 arranged for the  escape of Burgess and Donald Maclean (1913-1983) from Britain. In  1964, after the defection of Kim Philby, Blunt was confronted by British  authorities and secretly confessed his Soviet connections. When his past  as the �fourth man� in the spy ring was made public in 1979, he was  stripped of the knighthood awarded him in 1956.</p><p>Bly, Nellie orig. Elizabeth Cochrane (b.

Bly started writing for The Pittsburgh Dispatch at age 18, pro�  ducing feature articles on such subjects as divorce and slum life. After  joining the New York World, she feigned insanity to get into an asylum  and wrote an expose that brought about needed reforms. Beginning in  1889, in an attempt to beat the fictional record in Jules Verne�s Around the  World in Eighty Days, she circled the globe in about 72 days, 6 hours.  The much-publicized trip made her byname a celebrated synonym for a  female star reporter.</p><p>Bly, Robert (Elwood) (b. Dec. 23, 1926, Madison, Minn., U.S.) U.S.  poet and translator.

He helped found American  Writers Against the Vietnam War, and he donated his 1968 National Book  Award prize money (received for The Light Around the Body) to a draft  resisters� organization. His best-selling Iron John (1990) probed the male  psyche, and Bly became the best-known leader of the �men�s movement.�  In 2001 he published The Night Abraham Called to the Stars, poems uti�  lizing the Arabic ghazal form.

During World War II, BMW built the world�s first jet airplane  engines for the Luftwaffe. It suffered financially in the postwar period but  recovered after 1959 with a new line of conventionally designed high-  performance cars. The company�s turnaround was also credited to Ger�  man entrepreneur Herbert Quandt, who purchased a controlling share of  BMW�s stock in 1959. In the 21st century the firm�s brands included  BMW cars and motorcycles, MINI automobiles, and Rolls-Royce.

He began composing poetry  at age 5, and at age 28 he passed the examinations for the Chinese civil  service. He rose steadily in official life and became the informal leader  of a group of poets who rejected the courtly style of the time, believing  that poetry should have a moral and social purpose. His satirical ballads  and poems of social protest often took the form of free verse based on  old folk ballads. He was revered in both China and Japan, where his  poems, notably the �Song of Everlasting Sorrow,� became material for  other literary works.</p><p>bo tree See bodhi tree</p><p>boa Any of about 60 species of stout-bodied snakes (subfamily Boinae,  family Boidae) found in both the Old and New Worlds, mostly in warm  regions. Species vary in length from about 8 in. (20 cm) to more than 25  ft (7.5 m). Most are terrestrial or semiaquatic; some live in trees. Most  species have blotches and diamonds on their brown, green, or yellowish  body. Boas bite their prey, then kill by wrapping their body around the  prey and crushing it. Several species have heat-sensitive lip pits for detect�  ing warm-blooded prey, and most bear live young. Contrary to folklore,  boas are not dangerous to humans.</p><p>Boadicea See Boudicca</p><p>boar or wild boar or wild pig Any wild member of the pig species  Sus scrofa; the ancestor of domestic pigs.

(90 cm) tall  at the shoulder. Except for old, solitary males, boars live in groups. They  are omnivores and are good swimmers. They have sharp tusks and, though  normally not aggressive, can be dangerous. Because of its strength, speed,  and ferocity, the boar has long been a prized game animal.</p><p>Board of Trade See Board of Trade</p><p>Boas Vbo-,az\, Franz (b. July 9, 1858, Minden, Westphalia  [Germany]�d. Dec. 22, 1942, New York, N.Y., U.S.) German-bom U.S.  anthropologist. Trained in physics and geography (Ph.D., 1881), Boas was  part of an early scientific expedition to Baffin Island (1883-84), where he  turned to studying Eskimo culture. He later studied native peoples of Brit�  ish Columbia, including the Kwakiutl. From 1896 to 1905 he directed the  Jesup North Pacific Expedition, which investigated the relationships  between the aboriginal peoples of Siberia and North America. Teaching</p><p>at Columbia University from 1896  until his death, he was a leading  organizer of the profession in the  U.S. and the mentor of Ruth Bene�  dict, Alfred L. Kroeber, Margaret  Mead, and Edward Sapir. He is  largely credited with establishing  anthropology as an academic disci�  pline in the U.S. His achievements in  anthropology are virtually unrivaled.</p><p>Before Boas, most anthropologists  adhered to a relatively crude theory  of sociocultural evolution, arguing  that some peoples are inherently  more civilized or developed than  others. Boas argued that such views  are ethnocentric and that all human  groups have actually evolved equally  but in different ways. It is largely  because of Boas that anthropologists  now attribute human differences to historic �cultural,� rather than genetic,  factors. His books include The Mind of Primitive Man (1911), Primitive  Art (1927), and Race, Language, and Culture (1940).</p><p>boat people Refugees fleeing by boat. The term originally referred to  the thousands of Vietnamese who fled their country by sea following the  collapse of the South Vietnamese government in 1975. Crowded into  small vessels, they were prey to pirates, and many suffered dehydration,  starvation, and death by drowning. The term was later applied to waves  of refugees who attempted to reach the U.S. by boat from Cuba and Haiti  and also to Afghan and other refugees seeking asylum in Australia.</p><p>Bob and Ray in full Robert Brackett Elliott and Raymond  Walter Goulding (respectively b.

They met while working at a Boston radio  station and soon established their comic style in a program of parodies  and satire (1946-51). The Bob and Ray Show was nationally syndicated  (1951-53), and their comedy sketches were popular in the 1950s and �60s  on several networks. They also performed in the theatre and starred in the  Broadway show The Two and Only (1970).</p><p>bobbin Elongated spool of thread, used in the textile industry. In mod�  em processes, the spun fibres are wound on bobbins; the weft filling in  weaving comes off bobbins. Bobbins are essential to the manufacture of  bobbin lace (see lacemaking). The first bobbin lace probably originated in  Flanders in the early 16th century. Early bobbin lace consisted of rows  of deep acute-angled points worked from a narrow band, and the patterns  were usually similar to those of the needle laces. It was much used for  ruffs and collars in the 16th� 17th centuries. See also tapestry.</p><p>bobcat Bobtailed, long-legged North American cat ( Lynx rufus ) found  in forests and deserts from southern Canada to southern Mexico. It is a  close relative of the lynx and caracal. Bobcats have large paws and tufted  ears; are 24-40 in. (60-100 cm) long, excluding the 4-8-in. (10-20-cm)  tail; stand 20-24 in. (50-60 cm) at the shoulder; and weigh 15-33 lb (7�15  kg). The fur is pale brown to reddish with black spots. Bobcats are noc�  turnal and generally solitary. They feed on small mammals and some birds  and are important for controlling rodent and rabbit populations. They are  sometimes found in suburban areas.

He held positions at the  courts of Madrid and Prussia. His  vast chamber music output includes some 125 string quintets (more than  any other composer), some 90 string quartets, and many string trios. He  also wrote symphonies and cello concertos.

It is played on a long, narrow, packed-  clay court enclosed with boarded ends and sides. Each player or team in  turn rolls four balls (made of wood, metal, or composition material)  toward a smaller target ball. The object is to bring the ball to rest nearest  the target ball (for which points are awarded at the end of a round), to  protect a well-placed ball, or to knock aside an opponent�s ball.

In 1784 he invaded the  kingdom of Arakan and deported more than 20,000 of its people as slaves;  in 1785 he attempted to conquer Siam. His oppressive rule in Arakan led  to rebellion; his pursuit of rebel leaders across the border into British-  controlled Bengal nearly brought him into open conflict with the British.  His campaigns in Assam heightened tensions. A fervent Buddhist, he pro�  claimed himself Arimittya, the messianic Buddha destined to conquer the  world.</p><p>Bodensee See Lake Constance</p><p>Bode's law Rule giving the approximate distances of planets from the  Sun. First announced in 1766 by the German Johann Daniel Titius (b.  1729�d. 1796), it was popularized, from 1772, by his countryman Johann  Elert Bode (b. 1747�d. 1826). It may be given as follows: To each num�  ber in the sequence 0, 3, 6, 12, 24, and so on, add 4 and divide the result  by 10. The answers closely approximate the distances from the Sun, in  astronomical units, of the first seven planets. Bode�s law also suggested  that a planet should be found between Mars and Jupiter, where the aster�  oid belt was later discovered. Once thought to have some significance  regarding the formation of the solar system, it is now regarded as a  numerological curiosity.</p><p>bodhi Vbo-de\ (Sanskrit and Pali: �awakening� or �enlightenment�) In  Buddhism, the final enlightenment that ends the cycle of death and rebirth  and leads to nirvana. This awakening transformed Siddhartha Gautama  into the historical Buddha. Bodhi is achieved by ridding oneself of false  beliefs and the hindrance of passions through the discipline of the Eight�  fold Path.

Legend states that he trav�  eled from India to Guang (now Guangzhou), China, where he was granted  an interview with the emperor Wudi, who was famous for his good works.  He told the emperor that meditation, not good deeds, led to enlighten�  ment.

In Mahayana Buddhism the bodhisattva postpones  attainment of nirvana in order to alleviate the suffering of others. The ideal  supplanted the Theravada Buddhist ideals of the arhat and the self-  enlightened buddha, which Mahayana deemed selfish. The number of  bodhisattvas is theoretically limitless, and the title has been applied to  great scholars, teachers, and Buddhist kings. Celestial bodhisattvas (e.g.,  Avalokitesvara) are considered manifestations of the eternal Buddha and  serve as savior figures and objects of personal devotion, especially in East  Asia.</p><p>Bodin \b6-'da n \/ Jean (b. 1530, Angers, Fr.�d. June 1596, Laon)  French political philosopher. He studied at the University of Toulouse and  later taught law there (1551-61). In 1571 he entered the household of the  king�s brother, Francois, duke d�Alengon. He favoured negotiation with  the Huguenots, with whom the government was engaged in a civil war,  and opposed the sale of royal domains. His The Six Bookes of a Com-  monweale (1576) won him immediate fame. In it he suggested that the  key to securing order and authority lay in recognition of the state�s sov�  ereignty, which he believed derived from divine right and not from the  consent of the subject. He distinguished three types of government: mon�  archy (which he favoured), aristocracy, and democracy.</p><p>Bodleian \bod-Te-on\ Library Library of the University of Oxford and  one of the oldest and most important nonlending reference libraries in  Britain. The Bodleian is particularly rich in Asian manuscripts and col�  lections of English literature, local history, and early printing. Though it  was established earlier, it was not secured by the university until 1410.  After a period of decline, it was restored by Sir Thomas Bodley (1545�  1613), a collector of medieval manuscripts, and reopened in 1602. Under  provisions established in 1610 and 1662, it is a legal deposit library  entitled to free copies of all books printed in Britain.</p><p>Bodmer Vbod-morV Johann Georg (b. Dec. 6, 1786, Zurich,  Switz.�d. May 30, 1864, Zurich) Swiss inventor of machine tools and  textile-making machinery. In 1824 he established a small factory in  England to make textile machinery, and by 1833 he had a shop equipped  with his own machine tools. Between 1839 and 1841 he patented more  than 40 specialized machine tools that he then set up in an ingenious  factory-type arrangement. A gear-making machine that cut teeth of pre�  determined pitch, form, and depth in a metal blank was especially note�  worthy. Bodmer also patented various steam-engine devices and is credited  with inventing the cylinder with opposed pistons.</p><p>Bodoni Xbo-'do-neV Giambattista (b. Feb. 16, 1740, Saluzzo,  Piedmont�d. Nov. 29, 1813, Parma, French Empire) Italian typographer.  Son of a printer, he served an apprenticeship at the press of the Roman  Catholic Church in Rome. In 1768 he assumed management of the Royal  Press of the duke of Parma. By the 1780s he was designing his own type�  faces; the Bodoni typeface appeared in 1790 and is still in use today. He  became internationally known and collectors sought his books. His many  important works include fine editions of Horace (1791), Virgil (1793), and  Homer�s Iliad (1808).</p><p>Bodrum See Halicarnassus  body louse See human louse</p><p>body modification and mutilation Intentional modification of the  human body for religious, aesthetic, or social reasons. It is frequently per�</p><p>formed for magical or pseudo-medical purposes, but cosmetic motives are  equally common. The variability of the results in different cultures reflects  varying ideals of beauty or morality. Modifications include head flatten�  ing, insertion of a lip plug, tattoos, scarification, and piercing of the ear  and other parts of the body. Mutilations include male and female circum�  cision, foot binding, and amputation.</p><p>bodybuilding Developing of the physique through exercise and diet,  often for competitive exhibition. Bodybuilding aims at displaying pro�  nounced muscle tone and exaggerated muscle mass and definition for  overall aesthetic effect. Weight training is the principal form of exercise  used; high-protein foods and vitamin and mineral supplements contribute  to the diet. Bodybuilding competition grew largely out of 19th-century  European strongman theatrical and circus acts. The first important inter�  national competition was the Mr. Universe contest, founded in 1947. It  was followed in 1965 by the even more prestigious Mr. Olympia contest.  Competition for women began in the 1970s. In 1998 bodybuilding was  granted provisional status by the International Olympic Committee. The  use of steroids to enhance performance, though generally forbidden, has  long been common among bodybuilders.</p><p>Boehm Vb6em\, Theobald (b. April 9, 1794, Munich, Bavaria�d.  Nov. 25, 1881, Munich, German Empire) German flutist and flute  designer. Son of a goldsmith, he was a self-taught virtuoso flutist. Real�  izing that the craft he learned from his father could be put to use to  improve the instrument, he created a new kind of key mechanism in 1832.  He later studied acoustics, and by 1847 he had completely redesigned the  flute, giving it a different internal shape, moving the holes, and extending  the use of the keys. His work achieved a stronger and more uniform tone  than that of earlier instruments and formed the basis for the modern flute.</p><p>Boeing Co. Major U.S. firm that is the world�s largest aerospace com�  pany and foremost maker of commercial jet transports. It was founded by  William E. Boeing (1881-1956) in 1916 (as Aero Products Company). In  the late 1920s it became part of United Aircraft and Transport Corp., but  it reemerged as an independent entity in 1934 when that company was  broken up to comply with antitrust legislation. Boeing pioneered the  development of single-wing planes in the 1930s; its B-l 7 Flying Fortress  (first flown 1935) and B-29 Superfortress (1942) played prominent roles  in World War II. After the war the company developed the B-52 jet  bomber, long a mainstay of U.S. strategic forces. It produced the first U.S.  jetliner, the Boeing 707 (in service 1958), and went on to develop a highly  successful series of commercial jet transports. By the start of the 21st  century these formed seven families�the narrow-body 737 and 757;  wide-body 747, 767, and 777; 717 (formerly McDonnell Douglas  MD-95); and MD-11. In the 1960s Boeing built the Lunar Orbiters, Lunar  Roving Vehicles, and the first stage of the Saturn V rockets (see Saturn)  for the U.S. Apollo program. Beginning in 1993, it served as NASA�s  prime contractor for the International Space Station. In 1996 it purchased  the aerospace and defense units of Rockwell International Corp., and a  year later it bought McDonnell Douglas Corp. It acquired the satellite  business of Hughes Electronics in 2000. See also Lockheed Martin Corp.</p><p>Boeotia \be-'o-sh3\ District and ancient republic, eastern central Greece.  Bounded by Attica and the Gulf of Corinth, its chief cities were  Orchomenus and Thebes. Inhabited by Boeotians, an Aetolian people from  Thessaly, it became politically significant after the Boeotian League was  formed under Theban leadership c. 600-550 bc. Hostile to Athens, the  League revolted against it c. 447 bc. In the Peloponnesian War, Boeotia  defeated Athens at Delium in 424 bc. Led by Thebes, it dominated Greece  until Thebes was destroyed by Alexander the Great c. 335 bc.</p><p>Boer See Afrikaner</p><p>Boerhaave Vbiir-.ha-voV Hermann (b. Dec. 31, 1668, Voorhout,  Neth.�d.

Founded by a 10th-century  Bulgarian priest traditionally known as Bogomil, the sect�s beliefs arose  from the possible fusion of dualistic doctrines imported mainly from the  Paulicians (a sect of Armenia and Asia Minor) and a local Slavonic move�  ment aimed at reforming the new Bulgarian Orthodox church. Its central  teaching was that the visible, material world was created by the Devil.  The Bogomils taught a Docetist Christology instead of the traditional  doctrine of the Incarnation, rejected the Christian conception of matter as</p><p>a vehicle of grace, and repudiated the whole organization of the Ortho�  dox church. They were active missionaries who lived rigorously ascetic  lives. During the 11 th� 12th centuries Bogomilism spread over many  European and Asian provinces of the Byzantine Empire; it also spread  into western Europe, where it contributed to the formation of the Cathar  heresy. In Bulgaria it remained a powerful force until the late 14th cen�  tury. With the Ottoman conquest of southeastern Europe in the 15th cen�  tury, its influence declined.

It became the capital of the Vice�  royalty of New Granada and a centre of Spanish colonial power in South  America. It was the scene of revolt against Spanish rule (1810-11), and  the revolutionary leader Simon Bolivar took the city in 1819. It became the  capital of the confederation of Gran Colombia; when that entity was dis�  solved in 1830, it remained the capital but of New Granada and later the  Republic of Colombia.

He expounded this  insight in his work Aurora (1612). The writings of Paracelsus inspired his  interest in nature mysticism. In The Great Mystery (1623), he explained  the Genesis account of creation in terms of Paracelsian principles. In On  the Election of Grace, he expounded the free will problem, made acute at  the time by the spread of Calvinism and its doctrine of predestination. He  profoundly influenced later intellectual movements such as idealism and  Romanticism, and he is regarded as the father of theosophy.</p><p>Bohol \b6-'hol\ Island (pop., 2000: 1,137,268), Philippines.

Oct. 7, 1885, Copenhagen,  Den.�d. Nov. 18, 1962, Copenhagen) Danish physicist. He studied the  structure of the atom with J J. Thomson and Ernest Rutherford at the uni�  versities of Cambridge and Manchester. He was among the first to see the  importance of an element�s atomic number and postulated that any atom  could exist only in a discrete set of states characterized by definite val�  ues of energy. He became the first to apply the quantum theory to atomic  and molecular structure, and his concept of the atomic nucleus was a key  step in understanding such processes as nuclear fission. From 1920 to 1962  he directed the newly created Institute for Theoretical Physics in Copen�  hagen. His work on atomic theory won him a Nobel Prize for Physics in  1922. He was president of the Royal Danish Academy from 1939 until  his death. Though he contributed to atomic bomb research in the U.S.  during World War II, he later dedicated himself to the cause of arms con�  trol. He received the first U.S. Atoms for Peace Award in 1957. Element</p><p>107, bohrium, is named in his honour.

He also translated the clas�  sical treatise On the Sublime, attributed to Longinus, which ironically  became a key source of the aesthetics of Romanticism. His works upheld  classical standards in both French and English literature.</p><p>boiler Apparatus for converting a liquid to vapour. A boiler consists of a  furnace in which fuel is burned, surfaces to transmit heat from the com�  bustion products to the water (or other liquid), and a space where steam  (or vapour) can form and collect. A conventional boiler burns a fossil fuel  or waste fuel; a nuclear reactor may instead supply the heat. There are  two types of conventional steam boiler. In a fire-tube boiler, the water  surrounds the steel tubes through which hot gases from the furnace flow;  easy to install and operate, fire-tube boilers are widely used to heat build�  ings and to provide power for factory processes, as well as in steam loco�  motives. In a water-tube boiler, the water is inside tubes, with the hot  furnace gases circulating outside the tubes; water-tube boilers, which pro�  duce more and hotter steam, are used in ships and factories. The largest  are found in the central-station power plants of public utilities; other large  units are used in steel mills, paper mills, oil refineries, and chemical  plants. See also steam engine.</p><p>boiling Cooking of food by immersion in water, stock, or other liquid  heated to its boiling point. Boiling is used to cook meats, vegetables, and  some grain foods (pasta, for example). Scalding, accomplished by heat�  ing to about 185 �F (85 �C), is commonly used to prepare milk to be used  as an ingredient in various dishes. At just above the scalding temperature,  fish and eggs may be poached. At the simmering point, just below that of  boiling, soups, stews, and pot roasts may be prepared. Many foods, espe�  cially vegetables, are steamed in a rack placed above boiling water.</p><p>boiling point Temperature at which a liquid is converted to vapour  when heated. At the boiling point, addition of heat results in the transfor�  mation of the liquid into its vapour without an increase in temperature. A  liquid�s boiling point varies according to the liquid�s characteristics and  the applied pressure. Water at standard atmospheric pressure, or sea level,  boils at 212 �F (100 �C), while ethanol boils at about 172 �F (78 �C). At  higher altitudes, boiling points are lower and foods can take longer to  cook; pressure cookers can be used to increase the pressure so that the  boiling point is raised.</p><p>Bois, W.E.B.

In 1961 he  returned to head the army of the newly independent Central African  Republic; five years later he overthrew the president, his cousin David  Dacko. In 1977 he had himself crowned emperor. When he was found to  have participated in the massacre of 100 schoolchildren and was accused  of cannibalism, French paratroops removed him in a coup and reestab�  lished the republic. Bokassa settled in Cote d�Ivoire. He was sentenced  to death in absentia in 1980, but his death sentence was later commuted.</p><p>Bokhara See Bukhara</p><p>Bokn Fjord \ , biik- 3 n- , fyord\ Inlet of the North Sea, southwestern Nor�  way.

The son of a  Venezuelan aristocrat, Bolivar  received a European education.</p><p>Influenced by European rationalism,  he joined Venezuela�s independence  movement and became a prominent  political and military leader. The  revolutionaries expelled Venezuela�s  Spanish governor (1810) and  declared the nation�s independence  in 1811. The young republic was  defeated by the Spanish in 1814, and  Bolivar went into exile. In 1819 he  undertook a daring attack on New Granada, leading some 2,500 men over  routes considered impassable. Taking the Spanish by surprise, he defeated  them quickly. With the help of Antonio Sucre, he secured the indepen�  dence of Ecuador in 1822. He completed Jose de San Martin�s revolution�  ary work in Peru, freeing that country in 1824. On Bolivar�s orders, Sucre  liberated Upper Peru (1825). As president of both Colombia (1821-30)  and Peru (1823-29), Bolivar oversaw the creation in 1826 of a league of  Hispanic American states, but the new states soon began warring among  themselves. Less successful at ruling countries than at liberating them,  Bolivar exiled himself and died on his way to Europe.</p><p>Simon Bolivar, detail of an engraving  by C.G.

Area: 424,164 sq mi (1,098,581 sq km). Population (2005 est.):  8,858,000. Capitals: La Paz (administrative), Sucre (judicial). The popu�  lation consists of three principal groups: Indians, largely Aymara and Que-  chua; mestizos; and descendants of Europeans. Languages: Spanish,  Aymara, Quechua (all official). Religions: Christianity (predominantly  Roman Catholic [official]; also Protestant); also vestiges of pre-  Columbian religion. Currency: boliviano. Bolivia may be divided into  three major regions. The southwestern highlands, or Altiplano, where Lake  Titicaca is located, extends through southwestern Bolivia. It is enclosed  by the second region, the western and eastern branches of the Andes  Mountains. Much of the eastern branch is heavily forested terrain, with  many deep river valleys; the western branch is a high plateau bordered  by volcanoes, including the country�s highest peak, Mount Sajama, which  rises to 21,463 ft (6,542 m). The third region is a lowland area that com�  prises the northern and eastern two-thirds of the country; its rivers include  the Guapore, Mamore, Beni, and upper Pilcomayo. Bolivia has a develop�  ing mixed economy based on the production of natural gas and agricul�  tural foodstuffs. It is a republic with two legislative houses; its head of  state and government is the president. The Bolivian highlands were the  location of the advanced Tiwanaku culture in the 7th�11th centuries and,  with its passing, became the home of the Aymara, an Indian group con�  quered by the Inca in the 15th century. The Inca were overrun by the  invading Spanish conquistadorcs under Francisco Pizarro in the 1530s. By  1600 Spain had established the cities of Charcas (now Sucre), La Paz,  Santa Cruz, and what would become Cochabamba and had begun to exploit  the silver wealth of Potosf. Bolivia flourished in the 17th century, and for  a time Potosf was the largest city in the Americas. By the end of the cen�  tury, the mineral wealth had been depleted. Talk of independence began  as early as 1809, but not until 1825 were Spanish forces finally defeated.  Bolivia shrank in size when it lost Atacama province to Chile in 1884 at  the end of the War of the Pacific and again when it lost most of Gran  Chaco to Paraguay in 1938 as a result of the Chaco War.

Social and eco�  nomic tension continued in the early 21st  century, fueled by resistance to govern�  ment efforts to eradicate the growth of coca (from which the narcotic  cocaine is derived), by unrest among Bolivia�s Indians, and by disagree�  ments over how to exploit the country�s vast natural gas reserves.</p><p>Boll VbcelX, Heinrich (Theodor) (b.

Throughout the years, several classic genres emerged  from Bollywood: the historical epic, notably Mughal-e-azam (1960; �The  Great Mughal�); the curry western, such as Sholay (1975; �The Embers�);  the courtesan film, such as Pakeezah (1972; �Pure Heart�), which high�  lights stunning cinematography and sensual dance choreography; and the  mythological movie, represented by Jai Santoshi Maa (1975; �Hail San-  toshi Maa�). Star actors, rather than the films themselves, have accounted  for most box-office success. Standard features of Bollywood films include  formulaic story lines, expertly choreographed fight scenes, spectacular  song-and-dance routines, emotion-charged melodrama, and larger-than-  life heroes. At the beginning of the 21st century, Bollywood produced as  many as 1,000 feature films annually, and international audiences began  to develop among Asians in the U.K. and the U.S.</p><p>Bologna \bo-'lo-ny9\ City (pop., 2004 est.: 373,539), capital of Emilia-  Romagna region, northern Italy. Located north of Florence, it lies at the  northern foot of the Apennines. Originally the Etruscan town of Felsina,  it became a Roman military colony c. 190 bc. It was subject to the Byz�  antine exarchate of Ravenna from the 6th century ad. It became a free  commune in the 12th century. Incorporated into the Papal States in 1506,  it was the scene of the crowning of Charles V in 1530. After a brief period  of French occupation, it was restored to the Papal States in 1815, and in  1860 it was united to the Kingdom of Italy. The University of Bologna is  among Europe�s oldest. The city is a road and rail centre for traffic  between northern and southern Italy. It is the site of excellent medieval  and Renaissance architecture and is famous for its cuisine.

Though they joined  with their rivals, the Mensheviks (�members of the minority�), in the Rus�  sian Revolution of 1905, the two groups later split, and in 1912 Lenin  formed his own party. Its appeal grew among urban workers and soldiers  during World War I.

His first play appeared on Broadway in 1911, but  it was not until he began contributing to Broadway musicals that his fame  spread. In collaboration with P.G. Wodehouse and others, he wrote doz�  ens of scripts scored by composers such as Jerome Kern {Oh, Boy!, 1917),  George Gershwin {Lady, Be Good!, 1924; Girl Crazy, 1930), and Cole  Porter {Anything Goes, 1934).</p><p>Boltzmann \'bolts-,man\, Ludwig (Eduard) (b.

He was one of the first Euro�  pean scientists to recognize the importance of James Clerk Maxwell�s elec�  tromagnetic theory. He explained the second law of thermodynamics by  applying the laws of mechanics and the theory of probability to the  motions of atoms, and he is remembered as the developer of statistical  mechanics. His work was widely attacked and misunderstood; subject to  depression after 1900, he eventually committed suicide.

Aerial bombardment can be traced to the Italo-Turkish War (1911), in  which an Italian pilot dropped grenades on two Turkish targets. In World  War I Zeppelins and large two- to four-engined biplanes were used as stra�  tegic bombers. In the 1930s small dive bombers were developed; they  caused great destruction and panic in the Spanish Civil War and early in  World War II. The latter conflict saw further development of heavy stra�  tegic bombers, which were used to destroy targets in the enemy�s home  territory; meanwhile, smaller fighter-bombers supported ground troops on  the battlefield. After the war, jet-propelled long-range bombers carrying  nuclear bombs were important to Cold War strategy, and they also dropped  conventional bombs during the Vietnam War, the Persian Gulf War, and  the Afghan conflicts. Efforts to evade increasingly sophisticated electronic  early-warning systems have culminated in the development of U.S. stealth  bombers, but cheaper and smaller jet fighter-bombers, equipped with elec�  tronic sensors and guided �smart� bombs, have proved effective in con�  flicts ranging from the Balkans to the Middle East.</p><p>Bombon, Lake See Lake Taal</p><p>Bomu River \'bo-mu\ River, central Africa.

Common types are the English bond (courses of stretchers and headers  alternate), the Flemish or Dutch bond (headers and stretchers are laid  alternately within each course, each header being centered over the  stretcher below it), and the American bond (every fifth or sixth course  consists of headers, the rest being stretchers).

The issuer promises to pay interest on the debt when due  (usually semiannually) at a stipulated percentage of the face value and to  redeem the face value of the bond at maturity in legal tender. Bonds usu�  ally indicate a debt of substantial size and are issued in more formal fash�  ion than promissory notes, ordinarily under seal. Government bonds may  be backed by taxes, or they may be revenue bonds, backed only by rev�  enue from the specific project (toll roads, airports, etc.) to which they are  committed.

A bond is an incentive to  fulfill an obligation; it also provides reassurance that compensation is  available if the duty is not fulfilled. A surety usually is involved, and the  bond makes the surety responsible for the consequences of the obligated  person�s behaviour. See also bail.</p><p>Bond, (Horace) Julian (b.

When</p><p>atoms� nuclei and electrons interact, they tend to distribute themselves so  that the total energy is lowest; if the energy of a group arrangement is  lower than the sum of the components� energies, they bond. The physics  and mathematics of bonding were developed as part of quantum mechan�  ics. The number of bonds an atom can form�its valence �equals the  number of electrons it contributes or receives. Covalent bonds form mol�  ecules; atoms bond to specific other atoms by sharing an electron pair  between them. If the sharing is even, the molecule is not polar; if it is  uneven, the molecule is an electric dipole. Ionic bonds are the extreme of  uneven sharing; certain atoms give up electrons, becoming cations. Other  atoms take up the electrons and become anions. All the ions are held  together in a crystal by electrostatic forces. In crystalline metals, a dif�  fuse electron sharing bonds the atoms (metallic bonding). Other types  include hydrogen bonding; bonds in aromatic compounds; coordinate cova�  lent bonds; multicentre bonds, exemplified by boranes (boron hydrides),  in which more than two atoms share electron pairs; and the bonds in coor�  dination complexes (see transition element), still poorly understood.

A left-handed power hitter and a superb base  stealer, he played outfield for the Pittsburgh Pirates (1985-92) and the  San Francisco Giants (from 1993). By the early 21st century, he had  earned eight Gold Glove awards for fielding and had been named Most  Valuable Player six times. In 2001 he hit 73 home runs, breaking Mark  McGwire�s single-season record of 70; that year he also had 177 walks  to top Babe Ruth�s record (170). His father, Bobby Bonds (1946-2003),  was also an outstanding professional baseball player.</p><p>bone Rigid connective tissue of vertebrates, consisting of cells embedded  in a hard matrix. Bones serve as the body�s supporting framework, pro�  vide muscle-attachment points for movement, protect the internal organs,  house the blood-cell formation system (red bone marrow), and hold about  99% of the calcium vital to many body processes. Bone consists of a  matrix of crystals of calcium, chiefly the phosphate and carbonate, embed�  ded among collagen fibres, providing strength and elasticity, and bone  cells (less than 5% of its volume). An external layer of compact bone sur�  rounds a central area of spongy bone, except at the marrow cavity. Bone  does not grow by cell division; instead, different types of bone cells gen�  erate bone matrix, break it down, and maintain it. Bone is remodeled by  this process, which strengthens it in areas under greatest stress, permits  healing of fractures, and helps regulate calcium levels in body fluid (see</p><p>Q.</p><p>as</p><p>~o</p><p>physis (growth plate) epiphysis compact bone</p><p>Haversian</p><p>Volkmann</p><p>canal</p><p>periosteum</p><p>osteocyte</p><p>cancellous  (spongy) bone</p><p>cancellous  (spongy) bone</p><p>compact bone</p><p>medullary  containing marrow</p><p>periosteum-</p><p>metaphysis</p><p>Haversian</p><p>canal</p><p>Internal structure of a human long bone, with a magnified cross section of the inte�  rior. The central tubular region of the bone, called the diaphysis, flares outward  near the end to form the metaphysis, which contains a largely cancellous, or  spongy, interior. At the end of the bone is the epiphysis, which in young people is  separated from the metaphysis by the physis, or growth plate. The periosteum is a  connective sheath covering the outer surface of the bone. The Haversian system,  consisting of inorganic substances arranged in concentric rings around the Haver�  sian canals, provides compact bone with structural support and allows for metabo�  lism of bone cells. Osteocytes (mature bone cells) are found in tiny cavities between  the concentric rings. The canals contain capillaries that bring in oxygen and nutri�  ents and remove wastes. Transverse branches are known as Volkmann canals.</p><p>� MERRIAM-WEBSTER INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Bone &#x25BA; Bonn I 247</p><p>calcium deficiency). The process also causes underutilized bone, as in an  immobilized limb, to atrophy. Bone disorders include rheumatoid arthritis,  osteoarthritis, rickets, osteoporosis, and tumours. Bone can fracture sud�  denly or over time, as in stress fractures.</p><p>Bone See Annaba</p><p>bone china Hard-paste porcelain containing bone ash. It was developed  by Josiah Spode (1754-1827) in  England c. 1800. The addition of  bone ash to china stone and china  clay (i.e., hard china) made bone  china easier to manufacture; it is  stronger, does not chip easily, and  has an ivory-white colour that lends  itself to decoration. Other factories  (Minton, Derby, Worcester, Wedg�  wood, Rockingham) adopted the for�  mula in the early 19th century. Bone  china remains popular for tableware  in Britain and the U.S. See also  STONEWARE.</p><p>bone marrow or myeloid tis�  sue Soft, gelatinous tissue that fills  bone cavities. Red bone marrow con�  tains stem cells, progenitor cells, per-  cursor cells, and functional blood cells (see reticuloendothelial system).  Lymphocytes mature in the lymphoid organs (see lymphoid tissue). All other  blood-cell formation occurs in red marrow, which also takes part in  destruction of old erythrocytes (red blood cells). Yellow bone marrow  mainly stores fats. Because the leukocytes (white blood cells) produced in  bone marrow are involved in immune defenses, marrow transplants can  treat some types of immunodeficiency. Radiation and some anticancer drugs  can damage marrow and impair immunity. Bone-marrow examination helps  diagnose diseases related to blood and blood-forming organs.</p><p>bonefish Marine game fish ( Albula vulpes) that inhabits coastal and  island waters in tropical seas and is admired by anglers for its speed and  strength. Its maximum length is about 30 in. (76 cm), and its maximum  weight is 14 lbs (6.4 kg). The bonefish has a deeply notched caudal fin  (near the tail) and a small mouth beneath a pointed, piglike snout. It grubs  on the bottom for worms and other food.</p><p>bongo Large, brightly coloured antelope ( Boocercus , or Taurotragus,  eurycerus) found in dense forests of  central Africa.

March 16, 1822, Bordeaux, France�d.  May 25, 1899, Melun) French animal painter. She was trained by her  father, an art teacher, and began exhibiting regularly at the Paris Salon in  1841. Her unsentimental paintings of lions, tigers, horses, and other ani�  mals became very popular; The Horse Fair (1853) gained her an inter�  national reputation. A colourful personality, she dressed as a man to study  horses at the actual Horse Fair in Paris, receiving formal permission from  the police to do so. In 1865 she became the first woman to receive the  Grand Cross of the Legion of Honour.</p><p>Bonhoeffer Vbon- 1 hoe-f3r\ / Dietrich (b. Feb. 4, 1906, Breslau,  Ger.�d. April 9, 1945, Flossenbiirg) German Lutheran pastor and theo�  logian. He attended the Universities of Berlin and Tubingen, and from  1931 he lectured in theology at the University of Berlin. He became a  leading spokesman for the Confessing Church and was active in the resis�  tance movement under the guise of employment in military intelligence.  He was arrested and imprisoned in 1943. The discovery of documents</p><p>connecting him with the 1944 attempt on Adolf Hitler�s life led to his  execution a month before the end of World War II. One of the most  insightful theologians of the 20th century, he argued for a new vision of  Christianity that would abolish the division between the sacred and pro�  fane and abandon the traditional privileges of the church in favour of  active involvement in the world�s problems. His best-known works  include The Cost of Discipleship (1937), Ethics (1949), and Letters and  Papers from Prison (1951).</p><p>Boniface Vba-no-fosV Saint (b. 675, Wessex, Eng.�d. June 5, 754,  Dokkum, Frisia; feast day June 5) English missionary and reformer. Origi�  nally named Wynfrith, he became a Benedictine monk and then a priest.  He made two attempts to convert the Frisian Saxons; in 718 he journeyed  to Rome, where Pope Gregory II entrusted him with a mission to the  pagans east of the Rhine and gave him the name Boniface. In 722 at Hesse  he founded the first of many Benedictine monasteries. He was active for  10 years (725-735) in Thuringia. He established four bishoprics in  Bavaria, paving the way for its incorporation into the Carolingian empire.  He convened five synods (740-745) to reform the Frankish clergy and  Irish missionaries and a council (747) to reform the entire Frankish king�  dom. He was killed by a band of Frisians while reading the Bible to recent  converts.</p><p>Boniface of Querfurt, Saint See Saint Bruno of Querfurt</p><p>Boniface VIII orig. Benedict Caetani (b. c. 1235, Anagni, Papal  States�d. Oct. 11, 1303, Rome) Pope (1294-1303). Bom into an influ�  ential Roman family, Caetani studied law in Bologna and rose through  the papal government to become cardinal-deacon (1281) and pope. In  1296 his attempt to end hostilities between Edward I of England and Philip  IV of France became embroiled in the issue of taxation of clergy without  papal consent. When Boniface issued a bull forbidding such taxation,  Philip fought back with economic measures. They clashed again in 1301  over control of the clergy when Philip had a French bishop tried and  imprisoned. Eventually, hearing that Boniface planned to excommunicate  Philip, Philip�s supporters captured the pope; though rescued two days  later, he died shortly thereafter.</p><p>Bonifacio, Jose See Jose Bonifacio de Andrada e Silva</p><p>Bonin \'bo-nin\ Islands Japanese Ogasawara-shoto \o-,ga-sa-  'war-a-'sho-to\ Island group, western Pacific Ocean. Administratively part  of Japan and located about 600 mi (950 km) south of Tokyo, the group  consists of islands with a total area of about 40 sq mi (100 sq km). The  Bonins include some 30 mountainous islands such as Chichi (the largest),  Haha, Muko, and Yome. They were colonized in 1830 by a group of  Europeans and Hawaiians. The islands were formally annexed by Japan  in 1876; they were administered by the U.S. in 1945-68.</p><p>Bonington Vba-nirj-tanX, Richard Parkes (b. Oct. 25, 1801, Arnold,  Eng.�d. Sept. 23, 1828, London) British painter active in France. In 1818  he went to Paris to study with Antoine-Jean Gros. His skill in waterco�  lour, a novelty in Paris, attracted many imitators. He exhibited at the  famous �English� Salon of 1824 and won a gold medal. With John Con�  stable and J.M.W. Turner, he popularized the oil sketch, a rapidly executed  record of the transitory effects of nature. He became influential in England  and France as a master of the Romantic movement and a technical inno�  vator. His death at age 26 cut short a brilliant career.</p><p>bonito \b3-'ne-to\ Swift, predaceous schooling fishes (genus Sarda ) of  the mackerel family (Scombridae). Bonitos, found worldwide, have a  striped back and silvery belly and grow to about 30 in. (75 cm) long. Like  tunas, they are streamlined, with a narrow tail base, a forked tail, and a  row of small finlets behind the dorsal and anal fins. Bonitos have both  commercial and sporting value. The three generally recognized species  are found in the Atlantic and Mediterranean, the Indo-Pacific, and the  Pacific.</p><p>Bonn City (pop., 2002 est: city, 306,000; metro, area, 878,700), Ger�  many. Located on the Rhine River south of Cologne, it was, until 1990, the  capital of West Germany. An old settlement that predated the coming of  the Romans, its name was continued in Castra Bonnensia, a lst-century  Roman fortress. By the 9th century it had become the Frankish town of  Bonnburg. It grew from the 13th century, becoming capital of the Elec�  torate of Cologne. In 1815 Bonn was awarded to Prussia by the Congress  of Vienna, and by the late 19th century it was a fashionable residential  town. It was bombed heavily in World War II; its postwar redevelopment  was accelerated when in 1949 it was chosen as West Germany�s capital.</p><p>Wedgwood bone china plate, Stafford�  shire, 1815-20; in the Victoria and  Albert Museum, London.</p><p>COURTESY OF THE VICTORIA AND ALBERT MUSEUM,  LONDON: PHOTOGRAPH, EB INC.</p><p>Bongo (Boocercus euryceros).</p><p>TOM MCHUGH/PHOTO RESEARCHERS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>248 I Bonnard &#x25BA; booby</p><p>With Germany�s reunification in 1990, the national capital was moved to  Berlin.

He  studied at the Academie Julian and the Ecole des Beaux-Arts (1888-89).  In the 1890s he became a leading member of the Nabis group and came  under the influence of Art Nouveau and Japanese prints. With his friend  Edouard Vuillard, he developed the intimate domestic interior scene, a  genre known as Intimism, depicting fashionable Parisian life in the years  before World War I. He also produced still lifes, self-portraits, seascapes,  and large-scale decorative paintings. In 1910 he discovered the south of  France and began a series of luminous landscapes of the Mediterranean  region. He was fascinated by perspective, which he employed in paint�  ings such as The Dining Room (1913). From the 1920s he specialized in  landscapes, interiors, views of gardens, and bathing nudes. He produced  illustrations for the celebrated journal Revue blanche and decorative pages  for Paul Verlaine�s book of poetry Parallelement (1900). Bonnard was one  of the greatest colourists of modem art.</p><p>Bonnefoy, Yves (b. June 24, 1923, Tours, France) French poet. A stu�  dent of mathematics, Bonnefoy moved to Paris and came under the influ�  ence of the Surrealists. His poetry describes a thought universe brought to  life by an intuition of the �real world.� Among his poetry collections are In  the Shadow�s Light (1987), The Beginning and End of Snow (1991), and  New and Selected Poems (1995). Bonnefoy, also a scholar, compiled  Mythologies (1981), a dictionary of mythologies and religions. He held the  chair in comparative poetics at the College de France from 1981 to 1994.</p><p>Bonnet Vbo-'naV Georges-Etienne (b. July 23, 1889, Bassillac,  France�d.

He served as finance minister (1937-38) and foreign minister  (1938-39) and was a prominent supporter of appeasement of Nazi Ger�  many. He also supported the Vichy regime. After the liberation, proceed�  ings against him were started but dropped. He was expelled from the  Radical Party in 1944, readmitted in 1952, and again expelled in 1955.  He later served in the Chamber of Deputies (1956-68).</p><p>bonnet monkey Agile Indian macaque ( Macaca radiata) named for  the thatch of long hair forming a cap,  or �bonnet,� on the crown.

Its range, the lowland rainforests of  central Congo (Kinshasa), is more restricted than that of the chimpanzee,  and it has longer, more slender arms, a more slender body, and a less pro�  truding face. Bonobos eat mainly fruits but also leaves, seeds, grass, and  small animals. They form communities of 50-120 individuals. A striking</p><p>feature of their social lives is that they engage in sexual activity with great  frequency, often as a means of settling quarrels, and with little regard for  gender or age. Populations are shrinking, largely because of hunting and  habitat destruction, and bonobos are an endangered species.</p><p>Bononcini 'v.bo-non-'che-neV Giovanni (b.

His father  was Giovanni Maria Bononcini (1642-78), maestro di cappella of  Modena Cathedral and the composer of numerous church and chamber  sonatas. Giovanni himself served as maestro di cappella at San Giovanni  in Monte; he later held desirable positions in various European capitals.  In London in the 1720s he had a celebrated operatic rivalry with George  Frideric Handel. He wrote more than 30 operas, some 20 oratorios, and  nearly 300 cantatas (most for solo voice and continuo), but they are rarely  heard today. His brother Antonio Maria Bononcini (1677-1726) was also  a composer.</p><p>bonsai (Japanese: �tray planting�) Living dwarf tree or trees; also, the  art of training and growing them in  containers. Bonsai specimens are  ordinary trees and shrubs, not heredi�  tary dwarfs; they are dwarfed by a  system of pruning roots and  branches and training branches by  tying them with wire. The art origi�  nated in China but has been pursued  and developed primarily by the Japa�  nese. The direct inspiration for bon�  sai is found in nature, in trees that  grow in harsh, rocky places and are  dwarfed and gnarled throughout  their existence. Prized characteristics  are an aged-looking trunk and  branches and weathered-looking exposed upper roots. Bonsai may live  for a century or more and are handed down from one generation to another  as valued family possessions. Bonsai pots, usually earthenware and of  variable shape, are carefully chosen to harmonize in colour and propor�  tion with the tree. A sizable bonsai industry exists as part of the nursery  industry in Japan; California is home to a small-scale bonsai industry.</p><p>Bontemps\ban-'tam\, Arna(ud) (Wendell) (b.

His poetry began appearing in the black magazines Crisis and  Opportunity in the 1920s. With Countee Cullen he turned his first novel,  God Sends Sundays (1931), into the play St. Louis Woman. Two later nov�  els dealt with slave revolts. He edited anthologies with Langston Hughes  and wrote prolifically for children, mostly nonfiction works on African  Americans and African American history. He worked at Fisk University  for most of his adult life.</p><p>Bonus Army World War I veterans who gathered in Washington, D.C.,  in summer 1932 to demand payment of their promised bonuses. More than  12,000 veterans and their families camped near the U.S. Capitol, urging  support for a bill to force early payment of bonuses already voted by  Congress. When the bill was defeated, most of the crowd returned home,  but some angry protests caused local authorities to ask Pres. Herbert  Hoover for federal assistance. Army troops led by Gen. Douglas Mac-  Arthur drove out the protesters and burned their camps. The resulting  public outcry was a factor in Hoover�s defeat in the 1932 election. Another  group of veterans gathered in 1933, but Congress again rejected bonus  legislation. In 1936 Congress finally enacted a bill that paid nearly $2  billion in veterans� benefits.</p><p>bony fish Any member of the vertebrate class Osteichthyes, including  the great majority of living fishes and all the world�s sport and commer�  cial fishes. Also called Pisces, the class excludes jawless fishes (hagfishes  and lampreys) and cartilaginous fishes (sharks, skates, and rays). There are  more than 20,000 species worldwide, all with a skeleton at least partly  composed of true bone. Other features include, in most species, a swim  bladder (an air-filled sac to give buoyancy), gill covers over the gill cham�  ber, bony platelike scales, a skull with sutures, and external fertilization  of eggs.

The papyrus roll of ancient Egypt is  more nearly the direct ancestor of the modern book than is the clay tab�  let; examples of both date to c. 3000 bc. Somewhat later, the Chinese  independently created an extensive scholarship based on books, many  made of wood or bamboo strips bound with cords. Lampblack ink was  introduced in China c. ad 400 and printing from wooden blocks in the 6th  century. The Greeks adopted the papyrus roll and passed it on to the  Romans. The parchment or vellum codex superseded the papyrus roll by  ad 400. Medieval parchment or vellum leaves were prepared from the  skins of animals. By the 15th century, paper manuscripts were common.  Printing spread rapidly in the late 15th century. Subsequent technical  achievements, such as the development of offset printing, improved many  aspects of book culture. In the late 1990s, downloadable electronic books  became available over the Internet.</p><p>book club Marketing service that offers books to subscribers through  the mail, often at reduced prices. The first U.S. book club, the Book-of-  the-Month Club, was founded in 1926; the rival Literary Guild appeared  a year later. By the 1980s nearly 100 book clubs existed in the U.S., most  of them specialized (e.g., for history books, mysteries, etc.). A common  incentive for attracting new members is the offer of several free or heavily  discounted books; long-standing members often receive bonuses.</p><p>Book of Common Prayer Liturgical book used by the churches of  the Anglican Communion. First authorized for the Church of England in  1549, it went through several versions; the 1662 revision has remained  the standard (with minor changes) throughout the Commonwealth of  Nations. The Church of England and the Protestant Episcopal Church in  the U.S. adopted a liturgy in contemporary language in the 1970s.</p><p>Book of Kells Illuminated manuscript version of the four Gospels, c. late  8th-early 9th century. A masterpiece of the ornate Hiberno-Saxon style, it  features geometric design (rather than naturalistic representation), flat  areas of colour, and complex interlaced patterns. The illumination was  probably begun at the Irish monastery on the Scottish island of Iona; the  book was apparently taken to the monastery of Kells in County Meath,  Ire., after a Viking raid and may have been completed there. See also  Lindisfarne Gospels.</p><p>Book of the Dead Ancient Egyptian collection of mortuary texts made  up of spells and charms and placed in tombs to aid the deceased in the  next world. It was probably compiled and reedited during the 16th cen�  tury bc. Later compilations included hymns to Re. Scribes produced and  sold copies, often colorfully illustrated, for burial use. Of the many extant  copies, none contains all of the approximately 200 known chapters.</p><p>bookbinding Joining together of leaves of paper, parchment, or vel�  lum within covers to form a book or codex. Bookbinding developed when  the codex replaced the roll. Early bindings were often splendidly deco�  rated, but the typical artistic bookbinding is of decorated leather and was  first produced in the monasteries of Egypt�s Coptic Church. Rare books,  historical documents, and manuscripts may be bound by hand. The cover  (case) of the typical book is now affixed to the leaves by machine.</p><p>bookcase Piece of furniture fitted with shelves, formerly often enclosed  by doors.

It was established in 1968  by the multinational company Booker McConnell as a counterpart to the  French Prix Goncourt. The Booker Prize Foundation administers the prize,  aided by an advisory committee. Entries, which are nominated by publish�  ers, must be written by an English-language author from the United King�  dom, the Commonwealth countries, Ireland, or South Africa. Its winners  have included Kingsley Amis, A.S. Byatt, Ruth Prawer Jhabvala, and Salman  Rushdie. In 1992 a Booker Russian Novel Prize was introduced.</p><p>bookkeeping Recording of the money values of business transactions.  Bookkeeping provides the information from which accounts are prepared  but is distinct from accounting. Bookkeeping offers information on both  the current value, or equity, of an enterprise and on its change in value  (due to profit or loss) over a given time period. Managers require such  information to examine the results of operations and budget for the future;  investors need it to make decisions about buying or selling securities; and  credit grantors use it to determine whether to grant a loan. Financial  records were kept in Babylon and in ancient Greece and Rome. The  double-entry method of bookkeeping began with the development of the  Italian commercial republics of the 15th century. The Industrial Revolu�  tion stimulated the spread of bookkeeping, and 20th-century taxation and  government regulations made it a necessity. Two types of records con�  tinue to be used in bookkeeping�journals and ledgers. They can be  recorded by hand or entered into a computer. The journal contains daily  transactions (sales, purchases, etc.), while the ledger contains the record  of individual accounts. Each month an income statement and a balance  sheet are posted in the ledger.</p><p>bookmaking Gambling practice of determining odds and receiving  and paying off bets on the outcome of sporting events and other compe�  titions. Horse racing is perhaps most closely associated with bookmak�  ing, but boxing, baseball, football, basketball, and other sports have also  long been of interest to bookmakers (�bookies�) and gamblers. Morning-  line odds, established by legal bookmakers, are printed in the sports sec�  tions of newspapers throughout the U.S. Illegal bookmaking operations  have often been linked to organized crime. See also handicap.</p><p>bookplate Label with a printed  design pasted inside the front cover  of a book to identify its owner. It  probably originated in Germany in  the mid-15th century; the earliest  extant dated bookplate (1516) is Ger�  man. The earliest American example  is dated 1749. Bookplate designs  include portraits, views of libraries,  and landscapes, as well as symbols  of the owner�s interests or occupa�  tion (e.g., military trophies, palettes),  and, toward the end of the 19th cen�  tury, nude figures.</p><p>Boole, George (b.

About 12-30 in. (30-75 cm) in length,  the returning boomerang varies in shape from a deep curve to almost  straight sides of an angle. The ends are twisted or skewed in opposite  directions. It is held at one end, above and behind the thrower�s shoul�  der, and swung forward rapidly. Just before release, the thrower adds spin  by flicking the wrist so that the stick will loop around and return to him.  Returning boomerangs were used only in eastern and western Australia  as playthings, in tournament competition, and by hunters to imitate hawks  for driving flocks of game birds into nets. The longer, straighter, and  heavier nonreturning boomerang can kill animals and even humans.</p><p>boomslang Venomous snake (. Dispholidus typus ) of the savannas of  sub-Saharan Africa, the only species  of its family that is decidedly dan�  gerous to humans. When hunting, it  lies in wait in a bush or tree for cha�  meleons and birds; the forepart of the  body often extends motionless into  the air. The boomslang�s body and  eye colours are extremely variable  and provide excellent camouflage. In  defense it inflates its neck, showing  the dark skin between the scales, and  then may strike. Its venom causes  hemorrhages and can be fatal to  humans in small amounts.</p><p>Boone, Daniel (b. c. Nov. 2,</p><p>1734, Berks county, Pa.�d. c.

He  made several trips through the Cumberland Gap into eastern Kentucky  (1767, 1769-71) and in 1775 was employed to blaze a permanent trail,  called the Wilderness Road. He established the settlements of Boones-  boro and Harrodsburg. As a militia captain he defended Boonesboro  against the Indians; he was captured by the Shawnee in 1778 but escaped  after five months to warn Boonesboro of an impending attack. After los�  ing his Kentucky land claims in the late 1780s, he moved to the Missouri  Territory. His exploits were featured in a widely read history of Kentucky  and in Lord Byron�s epic poem Don Juan.</p><p>Boorman, John (b. Jan. 18, 1933, Shepperton, Middlesex, Eng.) Brit�  ish film director.

U.S. actor and assassin of Pres.  Abraham Lincoln. Born into a family of famous actors, he achieved suc�  cess in Shakespearean roles but resented the greater acclaim enjoyed by  his brother, Edwin Booth. A fanatical believer in slavery and the Southern  cause, he made plans with co-conspirators to abduct Lincoln; after sev�  eral failed attempts, he vowed to destroy the president and his cabinet. On  April 14, 1865, he shot Lincoln during a performance at Ford�s Theatre.  Though he broke his leg jumping from the president�s box, he was able  to escape on horseback to a Virginia farm. Tracked down, he refused to  surrender and was shot, either by a soldier or by himself.</p><p>Booth, William (b. April 10, 1829, Nottingham, Nottinghamshire,  Eng.�d. Aug. 20, 1912, London) British religious leader, founder and  general (1878-1912) of the Salvation Army. At age 15 he underwent a  religious conversion and became a revivalist preacher. In 1849 he went  to London, where he became a regular preacher of the Methodist New  Connection (1852-61) and then an independent revivalist. Aided by his  wife, Catherine Mumford Booth (1829-90), a fellow preacher and social  worker, he founded the Christian Mission in 1865, which in 1878 became  the Salvation Army. He traveled worldwide to lecture and organize  branches of the Army. His proposals for remedying social ills received  widespread acceptance and the encouragement of Edward VII.</p><p>Boothia Peninsula Peninsula, Nunavut, Canada. Almost an island, it  is the northernmost point of the North American mainland, reaching  71�58' N, and was formerly the location of the north magnetic pole. With  an area of 12,483 sq mi (32,330 sq km), it extends into the Arctic Ocean  and is separated from Baffin Island by the Gulf of Boothia and from Prince  of Wales Island by the Franklin Strait. It was discovered in 1829 by James  Clark Ross, who named it Boothia Felix for Sir Felix Booth, the expe�  dition�s financier. It is sparsely populated.</p><p>bootlegging Illegal traffic in liquor in the U.S. The term was probably  first used to describe the practice of concealing flasks of illicit liquor in  boot tops when going to trade with Indians. It became widely used in the  1920s when the 18th Amendment to the Constitution and the Volstead Act  of 1919 effected the prohibition of liquor manufacturing and sales. Early  bootleggers smuggled foreign-made liquor into the U.S. from Canada and  Mexico and from ships anchored in international waters. Later sources  included medicinal whiskey, denatured alcohol, and the manufacture of  com liquor. Bootlegging led to the rise of organized-crime syndicates that  controlled operations from the manufacture of liquor to its distribution in  restaurants and speakeasies. In 1933 Prohibition was repealed by the 21st  Amendment. Some counties and municipalities continue to ban liquor, and  bootlegging is still practiced.</p><p>bop See bebop</p><p>Bophuthatswana \,bo-pu-ta-'tswa-na\ Former political entity, South  Africa.

Lying on the Garonne River above its  junction with the Dordogne, Bordeaux has long been noted for its wine  production. As Burdigala, it was the chief town of the Bituriges Vivisci,  a Celtic people. Under Roman rule it was capital of Aquitania province.  As part of the inheritance of Eleanor of Aquitaine, Bordeaux became  English in 1154 on her husband�s accession to the English throne as Henry  II. It enjoyed great prosperity through a thriving trade with the English  until it was united with France on the English defeat in the Hundred Years'  War (1453). As a Girondin centre, it suffered severely in the French Revo�  lution. In 1870, during the Franco-Prussian War, the French government  was transferred to Bordeaux, as it was again in 1914 at the outbreak of  World War I. Its university, founded in 1441, educated such figures as  Montesquieu. The economy focuses on the service sector.</p><p>Borden, Sir Frederick (William) (b. May 14, 1847, Cornwallis,  Nova Scotia�d.

On Aug. 4, 1892, Lizzie (according to her testimony) discov�  ered her father and his wife dead in their home, brutally mutilated with a  sharp instrument. Lizzie and the maid admitted to being in the house at  the time of the murders. Lizzie was arrested and tried for both crimes, the  maid being suspected as an accomplice. Evidence against Lizzie included  her attempt to buy prussic acid (a poison) the day before the murders took  place. An ax, which some suspected was the murder weapon, was found  in the basement. Acquitted because of the circumstantial nature of the  evidence, she remained in Fall River until her death, largely ostracized by  the community.</p><p>Borden, Sir Robert (Laird) (b.

April 6, 1961, Brussels) Belgian bacteriologist  and immunologist. In 1895 he found that two blood serum components  cause bacteriolysis (bacterial cell-wall rupture), one a heat-stable antibody  in animals immune to the bacterium and the other a heat-sensitive comple�  ment in all animals. In 1898 he discovered hemolysis (rupture of foreign  erythrocytes), a similar process that also requires complement. This  research was vital to the foundation of serology, the study of immune  reactions in body fluids. His work with Octave Gengou led to serological  tests for many diseases, including typhoid, tuberculosis, and syphilis (the  Wassermann test). In 1906 they discovered Bordetella pertussis, which  causes whooping cough. In 1919 Bordet received a Nobel Prize.</p><p>Borduas Vbor-dui-'asV Paul-Emile (b.

He studied at the Copenhagen Music  Conservatory and later in Vienna and Berlin. Initially performing as a  concert musician, he soon developed a style that combined comedy with  classical music, and he toured throughout Europe. In 1940 he immigrated  to the U.S., where he achieved fame appearing in various venues, includ�  ing radio, films, concert halls, Broadway, and television. Though he per�  formed as soloist and guest conductor with many of the world�s leading  orchestras, his significant pianistic talent was often overshadowed by his  highly popular humour.</p><p>Borges Vbor-has\, Jorge Luis (b.

From  the 1920s on he was afflicted by a  growing hereditary blindness. In  1938 a severe head wound seemed to  free his deepest creative forces. His  blindness was total by the mid 1950s  and forced him to abandon the writ�  ing of long texts and begin dictating  his works. From 1955 he held the  honorary post of director of Argenti�  na�s national library. Much of his  work is rich in fantasy and meta�  phorical allegory, including the story  collections Ficciones (1944), which  won him an international following,  and The Aleph (1949).

They moved to Rome in the 16th cen�  tury and there, after Camillo Borghese was elected (1605) as Pope Paul  V, the family rose in wealth and fame. Prominent family members  included the adopted Scipione Caffarelli (later Borghese) (1576-1633), a  cardinal and patron of the arts, and Camillo F. L.

He was made archbishop of Valencia (1492) and cardinal  (1493). After his brother�s murder (1497), he took command of the papal  armies. In 1498 he resigned his ecclesiastical offices and married the sis�  ter of the king of Navarre, a move calculated to win French support for  a campaign to regain control of the Papal States. Acting in concert with  his father, Cesare won a series of military successes in the Papal States  (1499-1503), gaining a reputation for ruthlessness and assassination; his  political astuteness led Niccolo Machiavelli to cite him as an example of  the new �Prince.� Cesare�s gains proved fruitless, however, when his  father died (1503) and the new pope, Julius II, demanded that he give up  his lands. He escaped from prison in Spain and died fighting for Navarre.</p><p>Borgia, Lucrezia (b. April 18,</p><p>1480, Rome�d. June 24, 1519, Fer�  rara, Papal States) Italian noble�  woman.

Her three marriages  into prominent families helped aug�  ment the political and territorial  power of the Borgias. Her child may  have been the issue of an incestuous  relationship with her father.

Boris�s attempt to enforce mass bap�  tism set off a pagan rebellion, which he quelled, and he helped establish  the Bulgarian church. He sponsored missionaries to foster Slavic learn�  ing and the use of the Old Church Slavic language.

In  1921 he gave a very precise defini�  tion of quantity of heat, the most sat�  isfactory mathematical statement of  the first law of thermodynamics. In  1926 he collaborated with his stu�  dent Werner Heisenberg to develop  the mathematical formulation that  would adequately describe Heisen�  berg�s first laws of a new quantum  theory. He later showed, in the work  for which he is perhaps best known,  that the solution of the Schrodinger  equation has a statistical meaning of Max Born  physical significance.

Constructed with about 2  million cu ft (57,000 cu m) of gray  volcanic stone, it resembles a stepped  pyramid. Its base and first five ter�  races are square; the highest three ter�  races are circular. Reliefs on its  terrace walls represent the ascending  stages of enlightenment. The simple  and spacious upper circular terraces  carry 72 bell-shaped stupas, each con�  taining a statue of the Buddha.</p><p>Borodin \,b6r-9-'den\, Aleksandr (Porfiryevich) (b. Nov. 12,  1833, St. Petersburg, Russia�d. Feb. 27, 1887, St. Petersburg) Russian  composer. From 1862 he took lessons from Mily Balakirev; fired by nation�  alist sentiment, the two men became the core of the group of Russian  composers known as The Five. A professor of chemistry for much of his  life, he left a small compositional output, which includes the orchestral  suite In the Steppes of Central Asia (1880), two string quartets, and three  symphonies, the second of which has remained highly popular. His opera  Prince Igor �which contains the often-heard �Polovtsian Dances��was  left unfinished after 18 years of intermittent work.</p><p>Borodin \b9-r9-'dyen,\ English N.bor-o-'denX, Mikhail (Markovich)  orig. Mikhail Gruzenberg (b. July 9, 1884, Yanovichi, Russia�d.  May 29, 1951, Siberia) Russian diplomat. He joined the Bolshevik faction  in 1903, was arrested (1906), and lived in exile in the U.S. He returned  to Russia in 1917 and in 1923 was sent to China as an adviser to Sun  Yat-sen. There he built the loosely structured Nationalist Party (Guomin-  dang) into a highly centralized Leninist-style organization and helped the  Chinese Nationalists develop their army. After leaving China (1927), he  served as deputy director of the Tass news agency and editor of the Mos�  cow Daily News (1932^49). He was arrested in a Stalinist purge of Jew�  ish intellectuals and died in a Siberian labour camp.</p><p>Borodino, Battle of (Sept. 7, 1812) Bloody battle of the Napoleonic  Wars, fought during Napoleon�s invasion of Russia, near the town of  Borodino, about 70 miles (110 km) west of Moscow.

Pure crystalline boron is a black, lustrous, very hard but brittle semi�  conductor that does not occur naturally. Boron compounds are found  widely dispersed as various minerals, including borax and the gemstone  tourmaline. The element is used to harden certain steels, among other met�  allurgical uses, and is also used in semiconductor devices. Its borate com�  pounds, in which it has valence 3, are essential to plant growth and have  many uses in soaps, mild antiseptics, and eye ointments. Industrially, they  are used as herbicides, fire retardants in fabrics, and catalysts in numer�  ous organic chemical reactions. They are also used in electroplating and  glass and ceramic formulations. The exceptional hardness and inertness  of certain boron compounds, including boron carbide, aluminum boride,  and boron nitride (which has an electronic structure resembling that of  diamond), make them useful as abrasives and reinforcing agents, particu�  larly for high-temperature applications.</p><p>Borromeo \ I b6r-ro- , ma-o\ / Saint Charles (b. Oct. 1538, Arona,  duchy of Milan�d. Nov. 3, 1584, Milan; canonized 1610; feast day  November 4) Archbishop of Milan and leading figure in the Counter-  Reformation. He earned a doctorate in canon and civil law at the Univer�  sity of Pavia in 1559. His uncle, Pope Pius IV, appointed him cardinal and  archbishop of Milan in 1560. He was active in directing the Council of  Trent, and he later helped execute its decrees and draw up the Roman cat�  echism in 1566. He established seminaries and colleges in Milan and  nearby cities and gained renown for his heroic behaviour during the  plague of 1576-78.</p><p>Borromini, Francesco orig. Francesco Castelli (b. Sept. 25,  1599, Bissone, Duchy of  Lombardy�d. Aug. 2, 1667, Rome)</p><p>Italian Baroque architect. Though he  worked with Gian Lorenzo Bernini on  the design of the famous baldachin in  St. Peter's Basilica, the two later  became bitter rivals. Borromini�s  first independent commission was  the Roman church and monastery of  San Carlo alle Quattro Fontane  (1638-41), the dome of which  appears to float because its spring  points (see arch) and light sources are  concealed below. His works, com�  posed of flowing concave and convex  forms, contain spaces that are irregu�  lar ovals and polygons, as at Sant�Ivo  della Sapienza (1642-60). His for�  tunes declined in later years, and in 1667 he committed suicide. His influ�  ence was felt in northern Italy and central Europe in the next century.</p><p>Borsippa \bor-'si-p3\ Ancient city, Babylonia. Located southwest of  Babylon (near modern Al-Hillah, Iraq), its proximity to that capital helped  it become an important religious centre. Hammurabi built or rebuilt the  temple at Borsippa, dedicating it to the deity Marduk. During the reign of  Nebuchadrezzar II, the city reached its greatest prosperity. Borsippa was  destroyed by Xerxes I in the early 5th century bc and never fully recovered.</p><p>Interior of the dome of the church of S.

June 14, 1848, Alnwick,  Northumberland, Eng.�d. Feb. 8, 1923, London) British philosopher. He  helped revive in Britain the absolute idealism of G.W.F. Hegel and sought  to apply its principles to social and political problems. His debt to Hegel  is most evident in his works on ethics, aesthetics, and metaphysics. His  Some Suggestions in Ethics (1918) presents a view of reality as a synthe�  sis in which traditional oppositions such as pleasure/duty and egoism/  altruism are reconciled. His other works include Knowledge and Reality  (1885), Logic (1888), and History of Aesthetic (1892). His idealism was  attacked by G.E. Moore and Bertrand Russell.</p><p>Bosch \'bosh\, Hieronymus orig. Jeroen van Aken or Jerome  van Aken (b. c. 1450s, �s Hertogenbosch, Brabant�d. Aug. 9, 1516,  �s Hertogenbosch) Netherlandish painter. He was the son and grandson of  accomplished painters; his name comes from his native town of �s Her�  togenbosch. He enjoyed a successful career and was widely imitated. Of  the numerous works attributed to him, none can be dated precisely. His  paintings blend fantasy and reality in apocalyptic scenes of chaos with  half-human, half-animal creatures, devils, and demons interacting with  human figures in imaginary architecture and landscapes. Among his best-  known works is The Garden of Earthly Delights , depicting the dreams  that afflict people who live in a pleasure-seeking world. One of the most  original northern European artists of the late Middle Ages, he was an out�  standing draftsman and one of the first to make drawings as independent  works. He also produced decorative works, altarpieces, and stained-glass  designs.</p><p>Bosch (Gavino) \'bosh\, Juan (b. June 30, 1909, La Vega, Dom.  Rep.�d. Nov. 1, 2001, Santo Domingo) Scholar, poet, and president of  the Dominican Republic (1963). Bosch was raised in a lower-middle-class  family. Dismayed by the brutality of the dictator Rafael Trujillo, he spent  24 years in exile but returned after Trujillo�s death to build a leftist anti�  communist movement. After winning the first free presidential election in  38 years, he instituted liberal constitutional changes, many of which ben�  efited the country�s poor. His reforms, however, alienated landholders and  industrialists, and after only seven months in office Bosch was ousted in  a military coup. When his supporters revolted against the ruling junta in  1965, U.S. Pres. Lyndon B. Johnson, claiming that Bosch�s followers  were communists, sent troops to suppress the rebellion. Over the subse�  quent three decades, Bosch ran repeatedly but unsuccessfully for presi�  dent.</p><p>Bose Vbos\, Subhas Chandra (b. Jan. 23, 1897, Cuttack, Orissa,  India�d. Aug. 18, 1945, Taipei, Taiwan?) Indian revolutionary. Prepar�  ing in Britain for a career in the Indian civil service, he resigned his can�  didacy on hearing of nationalist turmoil back home. Sent by Mohandas  K. Gandhi to organize in Bengal, he was deported and imprisoned several  times. He favoured industrialization, which put him at odds with Gan�  dhi�s economic thought, and though he was elected president of the Indian  National Congress in 1938 and 1939, without Gandhi�s support he felt  bound to resign. He slipped out of India in 1941 and carried on his struggle  against the British from Nazi Germany and later from Southeast Asia. In  1944 he invaded India from Burma (Myanmar) with a small army of  Indian nationals and Japanese, but his army was soon forced to retreat.  He fled Southeast Asia after the Japanese surrender in 1945 and died of  bums suffered in a plane crash.</p><p>Bose-Einstein statistics One of two possible ways (the other is Fermi-  Dirac statistics) in which a collection of indistinguishable particles may  occupy a set of available discrete energy states. The gathering of particles  in the same state, which is characteristic of particles that obey Bose-  Einstein statistics, accounts for the cohesive streaming of laser light and  the frictionless creeping of superfluid helium (see superfluidity). The theory  of this behaviour was developed in 1924-25 by Satyendra Nath Bose  (1894-1974) and Albert Einstein. Bose-Einstein statistics apply only to  those particles, called bosons, which have integer values of spin and so do  not obey the Pauli exclusion principle.</p><p>Bosna Vbos-na\ River River, Bosnia and Herzegovina.

It is bounded by Serbia and Mon�  tenegro and by Croatia. Area: 19,772 sq mi (51,209 sq km). Population  (2005 est.): 3,853,000. Capital: Sarajevo. Major ethnic groups include  Bosniacs (Bosnian Muslims; about two-fifths of the population), Serbs</p><p>(about one-third), and Croats (about one-  fifth). Languages: Bosnian, Serbian,  j= &#x25A0; 1 &#x25A0; " |0 - ( � � mi Croatian (all official). Religions: Christian-</p><p>ity (mostly Eastern Orthodox; also Roman</p><p>Catholic), Islam. Currency: marka. The  country�s relief is largely mountainous, and elevations of more than 6,000  ft (1,800 m) are common. The land, drained by the Sava, Drina, and  Neretva rivers and their tributaries, drops abruptly southward toward the  Adriatic Sea. Agriculture is a mainstay of the economy; though the area  possesses a variety of minerals, it remains one of the poorest regions of  the former Yugoslavia. Bosnia and Herzegovina is a republic with two  legislative houses; its chief of state is the chairman of the tripartite presi�  dency, and the head of government is the chairman of the Council of  Ministers. Habitation long predates the era of Roman rule, during which  much of the country was included in the province of Dalmatia. Slav settle�  ment began in the 6th century ad. For the next several centuries, parts of  the region fell under the rule of Serbs, Croats, Hungarians, Venetians, and  Byzantines. The Ottoman Turks invaded Bosnia in the 14th century, and  after many battles it became a Turkish province in 1463. Herzegovina,  then known as Hum, was taken in 1482. In the 16th and 17th centuries  the area was an important Turkish outpost, constantly at war with the  Habsburgs and Venice. During this period much of the population converted  to Islam. At the Congress of Berlin after the Russo-Turkish War of 1877-  78, Bosnia and Herzegovina were assigned to Austria-Hungary, and they  were annexed in 1908. Growing Serbian nationalism resulted in the 1914  assassination of the Austrian archduke Francis Ferdinand at Sarajevo by a  Bosnian Serb, an event that precipitated World War I. After the war the  area became part of the Kingdom of Serbs, Croats, and Slovenes. Fol�  lowing World War II, the twin territories became a republic of commu�  nist Yugoslavia. With the collapse of communist regimes in eastern  Europe, Bosnia and Herzegovina declared its independence in 1992; its  Serbian population objected, and conflict ensued among Serbs, Croats,  and Muslims (see Bosnian conflict). A peace accord in 1995 established  a loosely federated government roughly divided between the Muslim-  Croat Federation of Bosnia and Herzegovina and the Serb Republic. In  1996 a NATO peacekeeping force was installed there.</p><p>Bosnian conflict (1992-98) Ethnically rooted war in Bosnia and Herze�  govina, a republic of Yugoslavia with a multiethnic population�44%  Bosniac (formerly known as Muslim), 33% Serb, and 17% Croat. Unrest  began with Yugoslavia�s breakup in 1990; after a 1992 referendum, the  European Community (now European Union) recognized Bosnia�s inde�  pendence. Bosnia�s Serbs responded violently, seized 70% of Bosnian  territory, besieged Sarajevo, and terrorized Bosniacs and Croats in what  came to be known as �ethnic cleansing.� After bitter fighting between the  Bosnian Croats and the Bosnian government, international pressure forced</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Bosnian crisis &#x25BA; Boswell I 255</p><p>the two factions to sign a cease-fire and an agreement for a federation.  Both then concentrated on their common enemy, the Serbs. After rejected  peace plans and continued warring, Western nations, with NATO back�  ing, imposed a final cease-fire negotiated at Dayton, Ohio, in 1995. Bos�  nia and Herzegovina became a single state composed of two distinct  entities. Today Bosnia and Herzegovina has three de facto monoethnic  entities, three separate armies and police forces, and a very weak national  government.

Russia  supported Serbia, which protested the annexation and demanded that Aus�  tria cede part of the territory to Serbia, but Austria-Hungary, supported by  Germany, threatened to invade Serbia if it persisted in its demands. Since  Russia could not risk war against both Germany and Austria-Hungary, it  was forced to accept the annexation. Though the crisis was resolved with�  out immediate warfare, it contributed to the outbreak of World War I.</p><p>boson \'bo-,zan\ Subatomic particle with integral spin that is governed by  Bose-Einstein statistics. Bosons include mesons, nuclei of even mass num�  ber, and the particles required to embody the fields of quantum field theory.

Connecting the Sea of Marmara with the Black Sea, it is 19 mi  (31 km) long and 2.8 mi (4.4 km) at its widest. Bosporus literally means  �ox ford�; it is traditionally connected with the legendary figure of Io,  who in the form of a heifer crossed the Thracian Bosporus in her wan�  derings. Because of its strategic importance for the defense of Constan�  tinople (modern Istanbul), which straddled its southern end, the Byzantine  emperors and later the Ottoman sultans constructed fortifications along its  shores. With the growing influence of the European powers in the 19th  century, rules were codified governing the transit of vessels through the  strait. An international commission assumed control of it after World War  I; Turkey resumed control in 1936. Two of the world�s longest bridges,  completed in 1973 and 1988, span the strait.</p><p>Bosporus, Kingdom of the or Cimmerian Bosporus Ancient  Greek kingdom, in modern southern Ukraine. It was first settled by Mile�  sians (6th century bc) at Panticapaeum, which later became the capital.  Gradually the kingdom grew to include all of the Crimea. It maintained  close ties with Athens in the 5th-3rd century bc, reaching the peak of its  power in the 4th century bc. It came under the rule of the kings of Pon-  tus after 110 bc. For 300 years it belonged to the Roman Empire, and  after ad 342 it was alternately under barbarian and Byzantine control.</p><p>Bosra See Bostra</p><p>Bossuet \b6-'swa\, Jacques-Benigne (b.

He was the most eloquent and influ�  ential spokesman for the rights of the French church against papal author�  ity in the 17th century. He is now chiefly remembered for his literary  works, including funeral panegyrics.</p><p>Boston Seaport city (pop., 2000: 589,141), capital of Massachusetts,  U.S. Located on Massachusetts Bay, an arm of the Atlantic Ocean, it is  the state�s largest city. Settled in 1630 by Puritan Englishmen of the Mas�  sachusetts Bay Company, Boston became the hub of the self-governing  Massachusetts Bay Colony under the leadership of Gov. John Winthrop. At  the forefront of the opposition to British trade restrictions on its Ameri�  can colonies, Boston was a locus of events leading to the American Revo�  lution: it was the scene of the Boston Massacre (1770) and Boston Tea  Party (1773). It was the centre for the antislavery movement (1830-65).  As the Industrial Revolution took hold in the U.S., Boston grew as an  important manufacturing and textile centre. Today financial and high-  technology industries are basic to the economy of the Boston area. Numer�  ous institutions of higher education are located there, including Boston  University. See also Cambridge.</p><p>Boston Globe, The Daily newspaper published in Boston, one of the  more influential newspapers in the U.S. Founded in 1872, it was pur�  chased in 1877 by Charles H. Taylor. Under his leadership, it began pub�  lishing morning and evening editions, increased local and regional</p><p>coverage, and introduced big headlines, especially on sensational stories.  In the 20th century, still headed by the Taylor family, the paper began  providing more national and international news while maintaining a gen�  erally liberal editorial stance. The New York Times Co. acquired the Globe  in 1993.</p><p>Boston Massacre Skirmish on March 5, 1770, between British troops  and a crowd in Boston. After provocation by the colonists, British sol�  diers fired on the mob and killed five men, including Crispus Attucks. The  incident was widely publicized by Samuel Adams, Paul Revere, and others  as a battle for American liberty, and it contributed to the unpopularity of  the British in the years before the American Revolution.</p><p>Boston Police Strike Strike in 1919 by most of Boston�s police force  to protest the police commissioner�s decision to deny them the right to  unionize. The mayor called in the city militia to restore order and break  the strike; Gov. Calvin Coolidge later sent in the state militia, which gave  him a reputation as a strong supporter of law and order and led to his  nomination as vice president on the 1920 Republican ticket.</p><p>Boston Strangler American serial killer who murdered at least 11 and  as many as 13 women in the Boston area between 1962 and 1964. The  killer�s first victim, a 55-year-old woman, was sexually assaulted and  strangled in her apartment on June 14, 1962. During the following months,  several other elderly women were murdered in similar circumstances,  though subsequent victims included young women. In 1965 Albert  DeSalvo, an inmate at a state mental hospital, confessed to the murders.  Although never charged with the killings because no physical evidence  tied him to the murder scenes, he was convicted on separate counts of  sexual assault and sentenced to life imprisonment. DeSalvo�s guilt  remains controversial, in part because his confessions demonstrated igno�  rance of many aspects of the crimes. DNA tests in 2001 confirmed that it  was all but impossible that DeSalvo was guilty of the last of the murders,  though it was one of the crimes to which he had confessed.</p><p>Boston Tea Party Incident on Dec. 16, 1773, in which American  patriots dressed as Indians threw 342 chests of tea from three British ships  into Boston Harbour. Their leader was Samuel Adams. The action was taken  to prevent the payment of a British-imposed tax on tea and to protest the  British monopoly of the colonial tea trade authorized by the Tea Act. In  retaliation, Parliament passed the punitive Intolerable Acts, which further  united the colonies in their opposition to the British.</p><p>Boston terrier Breed of dog developed in the late 19th century in Bos�  ton.

It was fought between the forces of King Richard III of  York and the contender for the crown, Henry Tudor (later Henry VII) of  Lancaster. The battle occurred when Henry returned from exile, landing  with an army at Milford Haven and meeting Richard�s forces 12 mi (19  km) west of Leicester. The king�s men were defeated and put to flight,  and Richard was unhorsed and killed in a bog (a scene depicted in Wil�  liam Shakespeare�s Richard III). The battle established the Tudor dynasty  on the English throne.</p><p>botanical garden or botanic garden Originally, a collection of  living plants designed to illustrate relationships within plant groups. Most  modern botanical gardens are concerned primarily with exhibiting orna�  mental plants in a scheme that emphasizes natural relationships. A display  garden of mostly woody plants (shrubs and trees) is often called an arbo�  retum. The botanical garden as an institution can be traced to ancient China  and many Mediterranean countries, where such gardens were often cen�  ters for raising plants used for food and medicines. Botanical gardens are  also reservoirs of valuable heritable characteristics, potentially important  in the breeding of new varieties of plants. Still another function is the  training of gardeners. The world�s most famous botanical garden is Kew  Gardens.</p><p>botany Branch of biology that deals with plants, including the study of  the structure, properties, and biochemical processes of all forms of plant  life, as well as plant classification, plant diseases, and the interactions of  plants with their physical environment. The science of botany traces back  to the ancient Greco-Roman world but received its modem impetus in  Europe in the 16th century, mainly through the work of physicians and  herbalists, who began to observe plants seriously to identify those useful  in medicine. Today the principal branches of botanical study are morphol�  ogy, physiology, ecology, and systematics (the identification and ranking  of all plants). Subdisciplines include bryology (the study of mosses and  liverworts), pteridology (the study of ferns and their relatives), paleobot�  any (the study of fossil plants), and palynology (the study of modern and  fossil pollen and spores). See also forestry, horticulture.</p><p>Botany Bay Inlet of the South Pacific Ocean, southeastern Australia.  Lying south of Sydney off Port Jackson, it is about 6 mi (10 km) at its  widest. It was the scene of the first Australian landing by Capt. James Cook  in 1770; he named the bay for its great variety of plants. It was selected  in 1787 as the site for a penal settlement, but the settlement was soon  transferred inland. Its shores are now ringed by Sydney�s suburbs.</p><p>Botero, Fernando (b. April 19, 1932, Medellin, Colom.) Colombian  painter and sculptor. He began painting as a teenager. By the time he  moved to New York City in 1960, he had developed his trademark style:  the depiction of round, corpulent humans and animals. In these works, his  use of flat, bright colour and boldly outlined forms reflected the influence  of Latin American folk art, while his strong compositions often emulated  the Old Masters. In 1973 Botero moved to Paris and began creating sculp�  tures that again focused on rotund subjects. Successful outdoor exhibi�  tions of his monumental bronze figures were staged around the world at  the end of the 20th century.</p><p>botfly Any member of several dipteran families with beelike adults and  larvae that are parasitic on mammals. Some species are serious pests of  horses, cattle, deer, sheep, rabbits, and squirrels, and one species (the  human botfly) attacks humans. Adults of several species lay many eggs  (nits) on the host�s body, and the emerging larvae penetrate its skin. The  larvae reemerge through the skin, then mature into egg-laying adults. In  the New World tropics, the botfly�s infestation of cattle has led to loss of  beef and hides. See also warble fly.</p><p>Botha Vbo-toV Louis (b. Sept. 27, 1862, near Greytown, Natal [South  Africa]�d. Aug. 27, 1919, Pretoria, Transvaal) First prime minister  (1910-19) of the Union of South Africa. Botha was elected to the South  African Republic�s parliament in 1897, where he sided with moderates  against Pres. Paul Kruger�s hostile policy toward Uitlanders (non-Boer,  mostly English, settlers). In the South African War he commanded south�  ern forces besieging Ladysmith and then tried unsuccessfully to defend</p><p>the Transvaal. As prime minister he sought earnestly to appease the  English-speaking population and was bitterly attacked by Afrikaner  nationalists. In World War I he acceded to British requests to conquer  German South West Africa (Namibia).</p><p>Botha, P(ieter) W(illem) (b. Jan. 12, 1916, Paul Roux, S.Af.) Prime  minister (1978-84) and first state president (1984-89) of South Africa.  Elected to parliament as a National Party candidate in 1948, Botha served  in several subsequent posts before replacing John Vorster as prime min�  ister in 1978. His government faced serious difficulties, including the  coming to power of black governments in Mozambique, Angola, and  Zimbabwe, an insurgency in South West Africa (Namibia), and domestic  unrest among black students and labour unions. Botha responded by back�  ing antigovernment troops in the bordering states and suppressing rebel�  lion at home. A target of criticism from within and outside his party, he  fell ill and resigned in 1989.</p><p>Bothnia, Gulf of Northern arm of the Baltic Sea. Extending between  Sweden and Finland, it covers about 45,200 sq mi (117,000 sq km). It is  450 mi (725 km) long and 50-150 mi (80-240 km) wide, with an aver�  age depth of 200 ft (60 m). Because many rivers drain into it, its salinity  is very low; annual ice cover consequently lasts up to five months.</p><p>Botox Trademark for botulinum toxin type A, a drug produced by the  bacterium Clostridium botulinum. It contains the same toxin that causes  severe food poisoning (botulism). When locally injected, Botox blocks  the release of the neurotransmitter acetylcholine, interfering with the abil�  ity of the muscle to contract. It is used to treat severe muscle spasm or  severe, uncontrollable sweating. Botox can also be used for cosmetic pur�  poses to treat facial wrinkles.</p><p>Botswana officially Republic of Botswana formerly Bechua-  naland V.bech-'wa-ns-.landX Country, southern Africa. Area: 224,848 sq  mi (582,356 sq km). Population (2005 est.): 1,765,000. Capital: Gabor-</p><p>of Khoekhoe and San, some of whom fol�  low a traditional nomadic way of life. Languages: English (official),  Tswana. Religions: Christianity (mostly independent and unaffiliated  Christians; also Protestant), traditional beliefs. Currency: pula. Botswana  is essentially a sand-filled basin, with a mean elevation of about 3,300 ft  (1,000 m). Part of the Kalahari Desert is in the southwest and west, while  the Okavango Swamp is in the north. The only sources of permanent sur�  face water are the Chobe River, which marks the Namibian boundary; the  Okavango River, in the far northwest; and the Limpopo River, which marks</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Botticelli &#x25BA; Boudicca I 257</p><p>the South African boundary in the southeast. The economy traditionally  depends on livestock raising; the development of diamond mining has  increased the country�s wealth. Botswana is a republic with one legisla�  tive body; its head of state and government is the president. The region�s  earliest inhabitants were the Khoekhoe and San. Sites were settled as early  as ad 190 during the southerly migration of Bantu-speaking farmers.  Tswana dynasties, which developed in the western Transvaal in the 13th�  14th centuries, moved into Botswana in the 18th century and established  several powerful states. European missionaries arrived in the early 19th  century, but it was the discovery of gold in 1867 that excited European  interest. In 1885 the area became the British Bechuanaland Protectorate,  remaining so until the 1960s. In 1966 the Republic of Bechuanaland was  proclaimed as an independent member of the British Commonwealth, and  later that year its name was changed to Botswana. Independent Botswana  tried to maintain a delicate balance between its economic dependence on  South Africa and its relations with the surrounding black countries; the  independence of Namibia in 1990 and South Africa�s rejection of apart�  heid eased tensions.</p><p>Botticelli X.bat-o-'chel-eV Sandro orig. Alessandro di Mariano  Filipepi (b. 1445, Florence�d. May 17, 1510, Florence [Italy]) Italian  Renaissance painter. As a youth he may have been apprenticed to a gold�  smith, and he later trained with Fra Filippo Lippi in Florence. By 1470 he  had developed a distinctive style and was established as a master. In 1481  he was among a team of Florentine and Umbrian artists called to Rome  to decorate the Sistine Chapel; three of his finest religious frescoes (com�  pleted 1482) can be seen there. Though prolific as a painter of religious  images, his mythological paintings are his best-known works. His out�  standing portraits show the influence of contemporary Flemish art in the  placement of the figure in front of a landscape. Among his greatest works  are the Primavera, Pallas and the Centaur, Venus and Mars, and The Birth  of Venus, all painted c. 1477-90. About 75 of his paintings survive, many  of them in the Uffizi Gallery in Florence. Interest in his work revived in  the 19th century, and today he is one of the most esteemed painters of the  Italian Renaissance.</p><p>The Birth of Venus, oil on canvas by Sandro Botticelli, c. 1485; in the Uffizi,  Florence.</p><p>ART MEDIA/HERITAGE-IMAGES</p><p>bottlenose dolphin or bottle-nosed dolphin Widely recognized  species ( Tursiops truncatus) of mammal belonging to the dolphin family,  found worldwide in warm and temperate seas. Bottlenose dolphins reach  an average length of 8-10 ft (2.5-3 m) and weight of 300-650 lb (135�  300 kg). Males are generally larger than females. A familiar performer at  marine shows, the species is characterized by a �built-in smile� formed  by the curvature of its mouth. It has also become the subject of scientific  studies because of its intelligence and its ability to communicate with its  kind through sounds and ultrasonic pulses.</p><p>bottom water Lowermost layer of ocean water that can be distin�  guished by its characteristic low temperature, high density, and low oxygen  content compared with surface waters. Most bottom waters are formed near  Antarctica during the southern winter. The partial freezing of seawater over  the Antarctic continental shelf produces salt-free ice and residual brine  with a high density, which causes it to sink; it then flows northward along  the seafloor. The Arctic Ocean is less important as a source of bottom water</p><p>because it is isolated by barriers such as the Bering Sill and submarine  ridges and banks between Greenland and the British Isles.</p><p>botulism Vba-cho-.li-zomX Poisoning by botulinum toxin, one of the  most potent toxins known, produced by Clostridium botulinum bacteria.  It usually results from improperly sterilized canned (mostly home-canned)  foods. Heat-resistant spores of these anaerobic bacteria in fresh food may  survive canning. The bacteria multiply and secrete toxin, which remains  potent if the food is not well heated before it is eaten. Botulism can also  result from wound infection. Botulinum toxin blocks nerve-impulse trans�  mission. If botulism is recognized in time, administered antitoxins can  neutralize it. The first symptoms of botulism are nausea and vomiting,  which usually appeal - six hours or less after the contaminated food is eaten.  Fatigue, blurry vision, and general weakness follow. Respiratory paraly�  sis can cause death if not treated with emergency tracheotomy and res�  piratory aid. Most victims recover completely if they survive paralysis.  The bacteria�s intense toxicity makes it a potentially deadly biological  warfare agent.</p><p>Bouake \bwa-'ka\ City (pop., 1995 est.: 330,000), central Cote d�Ivoire.

In 1723 he won the Prix de Rome,  but he was unable to travel to Italy until 1728. For his first major com�  mission he produced 125 engravings of drawings by Antoine Watteau. He  executed important decorative commissions for Madame de Pompadour at  Versailles. His playful style and frivolous subject matter exemplify the  Rococo style and embody the elegant superficiality of French court life in  the mid 18th century. He became a member of the Royal Academy in  1734, a principal designer for the royal porcelain factories, and director  of the Gobelins tapestry factory. In 1765 he was appointed director of the  Royal Academy and first painter to Louis XV. One of the great painters  and draftsmen of the 18th century, he mastered every branch of decora�  tive and illustrative painting.</p><p>Boucher Vbau-choiA, Jonathan (b.

As rector of Annapolis,  Md., he tutored George Washington�s stepson and became a family friend.  His royalist views cost him his position and he was forced to return to  England in 1775. In his retirement he wrote A View of the Causes and  Consequences of the American Revolution (1779); his glossary of �archaic  and provincial words� was later used for Noah Webster�s dictionary.</p><p>Boucicault \'bu-si-,ko\, Dion orig.

He was impris�  oned by the French from 1956 until Algerian independence in 1962,  whereupon he became deputy premier under Ben Bella in the new gov�  ernment. His opposition to Ben Bella�s autocratic style led to a 27-year  exile. In 1992 he was invited back to head the government and to deal  with rising religious influence in political affairs.

In 1874 he exhibited with the Impressionists, but, unlike  those painters, he was not an innovator, and from 1863 to 1897 he exhib�  ited regularly in the official Salon. His favourite subjects were beach  scenes and seascapes, which show remarkable sensitivity to effects of  atmosphere; on the backs of his paintings he recorded the weather, light,  and time of day. His works link the careful naturalism of the mid 19th  century and the brilliant colours and fluid brushwork of Impressionism.</p><p>boudinage \,biid- 3 n- , azh\ Cylinder-like structures making up a layer of  deformed rock.

The Emperor  Range, with its highest peak at Balbi (9,000 ft [2,743 m]), occupies the  northern half of the island, while the Crown Prince Range occupies the  southern half. It was visited by Louis-Antoine de Bougainville in 1768,  and it came under German control in the late 19th century. After World  War I it was included in an Australian mandate. Following World War II  it was made part of the UN Trust Territory of New Guinea, and it passed  to Papua New Guinea when that country became independent in 1975.

Commissioned by the  government to circle the Earth in a voyage of exploration, he put to sea  in 1766; after touching Samoa and the New Hebrides he continued west  into waters not previously navigated by any European. He turned north  on the fringes of the Great Barrier Reef and did not sight Australia. He  stopped in the Moluccas and in Java before returning to Brittany in 1769.  His widely read Voyage Round the World (1771) helped popularize a  belief in the moral worth of people in their natural state. He was secre�  tary to Louis XV (1772), led the French fleet in support of the American  Revolution, and was named to the Legion of Honour by Napoleon.

On his return from Italy in 1854, he became a successful  proponent of academic painting and was instrumental in the exclusion of  the radical Impressionists from the official Salon. Working in a smooth,  highly finished style, he painted sentimental religious works, coyly erotic  nudes, allegorical scenes, and realistic portraits. In 1876 he was elected  to the Academy of Fine Arts. His influence was felt widely, particularly  in the U.S.</p><p>Bouillaud \bu-'yo\, Jean-Baptiste (b. Sept. 16, 1796, Garat, Fr.�d.

Inspired by the works of Anton Webern, in the 1950s he  began to experiment with total serialism; his serialist music is marked by a  sensitivity to the nuances of instrumental texture and colour. In 1954 he  founded a series of avant-garde concerts, the Domaine Musicale. His  important works include Le Soleil des eaux (1948), Structures I and II  (1952, 1961), Le Marteau sans maitre (1957), Pli selon pli (1962), and  three piano sonatas. By the 1960s he had gained an international reputation  not only as a composer but also as a conductor, particularly of the 20th-  century repertoire. He was chief conductor of the BBC Symphony Orches�  tra (1971-74) and conductor of the New York Philharmonic (1971-78). In  1974 he founded the French national experimental studio IRC AM.

In 1672 Louis XIV appointed him royal  cabinetmaker at Versailles; his other patrons included Philip V of Spain and  the duke of Bourbon. Boulle stretched the technique of marquetry to new  heights, and his incorporation of elaborate brasswork and the inlaying of  exotic woods (called boulle or buhl work, since his last name sometimes  appeared as Buhl) was heavily imitated in the 18th�19th centuries.</p><p>Boullee \bii-'la\, Etienne-Louis (b.

Through his investigation  of the properties of geometric forms, to which he attributed innate sym�  bolic qualities, Boullee achieved a pure, modern Classicism. His greatest  influence was as a teacher and theorist. In a series of theoretical plans for  public monuments, culminating in the design (1784) for an immense  sphere that would serve as a cenotaph honouring Isaac Newton, he gave  imaginary form to his theories.</p><p>Boulogne, Jean See Giambologna</p><p>Boulsover Vbol-.zo-voA, Thomas (b. 1706, Elkington, Derbyshire,  Eng.�d.

In the late 1940s, after moving to New  York City with her American husband, she turned to sculpture. She  achieved recognition in the 1950s with wooden constructions painted  uniformly black or white. She also worked in marble, plaster, latex, and  glass. Though her works are abstract, they are suggestive of the human  figure and express themes of betrayal, anxiety, and loneliness.</p><p>bourgeoisie X.burzh-.wa-'zeX In social and political theory, the social  order dominated by the property-owning class. The term arose in medi�  eval France, where it denoted the inhabitant of a walled town. The con�  cept of the bourgeoisie is most closely associated with Karl Marx and  those who were influenced by him. According to Marx, the bourgeoisie  plays a heroic role in history by revolutionizing industry and moderniz�  ing society; however, it also seeks to monopolize the benefits of modern�  ization and exploit the property-less proletariat, thereby creating  revolutionary tensions. The end result will be a final revolution in which  the property of the bourgeoisie is expropriated and class conflict, exploi�  tation, and the state are abolished. Much employed by 19th-century social  reformers, the term had nearly disappeared from the vocabulary of politi�  cal writers and politicians by the mid 20th century. In popular speech, it  connotes philistinism, materialism, and a striving concern for �respect�  ability.� See also social class.</p><p>Bourges, Pragmatic Sanction of See Pragmatic Sanction of  Bourges</p><p>Bourguiba \bur-'ge-bo\, Habib (ibn Ali) (b.

Versions  of the game have existed since ancient times. Ninepin bowling was  brought to the U.S. in the 17th century by Dutch settlers; it became so  popular and so associated with gambling that it was outlawed in several  states. The game grew to enormous popularity in the 20th century, both  as a recreational activity and (since 1958) as a professional sport. If all  the pins are knocked down with the first ball, a strike is recorded (10  points). If pins remain standing but the second ball knocks them down,  the player is awarded a spare (10 points). If a strike is thrown in a frame  (turn), the number of pins knocked down by the next two balls bowled  count in that frame. After a spare, the score of the next ball counts in the  spare�s frame. Thus, the maximum point total for a single frame is 30.  Each game is divided into 10 frames, and each player is allowed to deliver  up to two balls per frame (except in the final frame, in which two addi�  tional deliveries are permitted following a strike [one additional follow�  ing a spare]. A perfect score is 300, or 12 strikes in a row. Versions of  the game include candlepins, duckpins, and skittles.</p><p>bowls or lawn bowls or lawn bowling Bowling game similar to  the Italian boccie and the French boules played on a green with wooden  balls (called bowls) that are rolled at a target ball (the jack). The object  is to roll one�s bowls so that they come to rest nearer to the jack than  those of an opponent, sometimes achieved by knocking aside an oppo�  nent�s bowl or jack. One point is awarded for each winning bowl. Depend�  ing on the game, players use four, three, or two bowls, and games end at  18 or 21 points.</p><p>Bowman Vbo-monV Sir William (b. July 20, 1816, Nantwich,  Cheshire, Eng.�d. March 29, 1892, near Dorking, Surrey) English sur�  geon and histologist. His studies of organ tissues with his teacher Robert  Todd led to major papers on the structure and function of voluntary muscle  and of the kidneys and on the detailed anatomy of the liver. In the kid�  neys, he found that the capsule (Bowman capsule) surrounding each glom�  erulus (ball of capillaries) in the nephrons is a continuous part of the renal  duct. This was of prime importance to his filtration theory of urine for�  mation, key to understanding kidney function. Bowman and Todd pub�  lished The Physiological Anatomy and Physiology of Man (2 vol., 1845�  56), a pioneering work in both physiology and histology. Turning to the  eye, Bowman became one of the world�s foremost ophthalmic research  scientists, London�s outstanding eye surgeon, and the first to describe  several eye structures and their functions.</p><p>box In botany, an evergreen shrub or small tree (genus Buxus) of the box  family (Buxaceae), best known for the ornamental and useful boxwoods.  The family comprises seven genera of trees, shrubs, and herbaceous  plants, native to North America, Europe, North Africa, and Asia. The  plants bear male and female flowers, without petals, on separate plants.  The leathery, evergreen leaves are simple and alternate. Fruits are one- or  two-seeded capsules or drupes. Three species of the genus Buxus provide  the widely grown boxwood: the common, or English, box ( B . sempervi-  rens), used for hedges, borders, and topiary figures; the Japanese box ( B.  microphylla)\ and the tall boxwood tree (B. balearica).</p><p>box elder Hardy and fast-growing tree ( Acer negundo ), also called  ash-leaved maple, of the maple family, native to the central and eastern U.S.  Its compound leaves (rare among maples) consist of three, five, or seven  coarsely toothed leaflets. The single seed is borne in a samara (dry, winged  fruit). Because of its rapid growth and its drought resistance, it was widely  planted for shade by early settlers in the prairie regions of the U.S. Maple  syrup and sugar are sometimes obtained from the box elder. Its wood is  used for crates, furniture, paper pulp, and charcoal.</p><p>box turtle Any of several species of terrestrial turtle (genus Terrapene)  found in the U.S. and Mexico. Box  turtles have a high, rounded upper  shell (carapace) that grows to a  maximum length of about 7 in. (18  cm). The lower shell (plastron) is  hinged across the center and can be  drawn very tightly against the cara�  pace to form a protective �box� that  completely encloses the turtle�s soft  parts. They feed on earthworms,  insects, mushrooms, and berries.</p><p>Box turtles are often kept as pets.</p><p>boxer Smooth-haired breed of working dog named for its manner of  �boxing� with its sturdy front paws  when beginning to fight.

Support for  them grew in northern China during the late 19th century, when China�s  people were suffering from growing economic impoverishment and the  country was forced to grant humiliating concessions to Western powers.  In June 1900, after Boxers had killed Chinese Christians and Westerners,  an international relief force was dispatched to quell the attacks. The  empress dowager, Cixi, ordered imperial forces to block its advance; the  conflict escalated, hundereds of people were killed, and the matter was  not resolved until August, when Beijing was captured and sacked. Hos�  tilities were ended with a protocol (1901) requiring China to pay a large  indemnity to 11 countries. Britain and the U.S. later returned much of  their reparations, the U.S. using its portion to further Chinese higher edu�  cation. See also U.S. Open Door policy.</p><p>boxing Sport involving attack and defense with the fists. In the mod�  ern sport, boxers wear padded gloves and fight bouts of up to 12 three-  minute rounds in a roped-off square known as the ring. In ancient Greece  fighters used leather thongs on their hands and forearms, while in Rome  gladiators used metal-studded leather hand coverings (cesti) and usually  fought to the death. Not until implementation of the London Prize Ring  rules in 1839 were kicking, gouging, butting, biting, and blows below the  belt eliminated from the boxer�s standard repertoire. In 1867 the Queens-  berry rules called for the wearing of gloves, though bare-knuckle boxing  continued into the late 1880s. The last of the great bare-knuckle fighters  was John L. Sullivan. From Sullivan on, the U.S. became the premier box�  ing venue, partly because immigrants supplied a constantly renewed pool  of boxers. Boxing has been included among the Olympic Games since  1904. Today there are 17 primary weight classes in professional boxing;  straw weight, to 105 lbs (48 kg); junior flyweight, to 108 lbs (49 kg); fly�  weight, to 112 lbs (51 kg); junior bantamweight, to 115 lbs (52 kg); ban�  tamweight, to 118 lbs (53.5 kg); junior featherweight, to 122 lbs (55 kg);  featherweight, to 126 lbs (57 kg); junior lightweight, to 130 lbs (59 kg);  lightweight, to 135 lbs (61 kg); junior welterweight, 140 lbs (63.5 kg);  welterweight, to 147 lbs (67 kg); junior middleweight, 154 lbs (70 kg);  middleweight, to 160 lbs (72.5 kg); super middleweight, 168 lbs (76 kg);  light heavyweight, to 175 lbs (79 kg); cruiserweight, 190 lbs (86 kg); and  heavyweight, over 190 lbs. A bout can be won either by knocking out or  felling one�s opponent for a count of 10 (a KO) or by delivering the most  solid blows and thus amassing the most points. The referee can also stop  the fight when one boxer is being badly beaten (a technical knockout, or  TKO) or he can disqualify a fighter for rules violations and award the  fight to his opponent.</p><p>Boy Scouts See scouting</p><p>boyar \bo-'yar\ Any male member of the upper class of medieval Rus�  sian society and state administration. In Kievan Rus (10th-12th centuries)  the boyars belonged to the prince�s retinue, holding posts in the army and  civil administration and advising the prince in matters of state through a  boyar council, or duma. In the 13th-14th centuries the boyars constituted  a privileged class of rich landowners in northeastern Russia. In the 15th-  17th centuries the boyars of Muscovy ruled the country along with the  grand prince (later the czar) and legislated through the boyar council.  Their importance declined in the 17th century, and the title was abolished  by Peter I in the early 18th century.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>boycott &#x25BA; Bradlee I 263</p><p>boycott Collective and organized ostracism applied in labour, economic,  political, or social relations to protest and punish practices considered  unfair. The tactic was popularized by Charles Stewart Parnell to protest  high rents and land evictions in Ireland in 1880 by the estate manager  Charles C. Boycott (b. 1832�d. 1897). Boycotts are principally used by  labour organizations to win improved wages and working conditions or by  consumers to pressure companies to change their hiring, labour, environ�  mental, or investment practices. U.S. law distinguishes between primary  boycotts, which consist of the refusal by employees to purchase the goods  or services of their employers, and secondary boycotts, which involve  attempts to induce third parties to refuse to patronize the employer. The  latter type of boycott is illegal in most states. Boycotts were used as a tac�  tic in the U.S. civil rights movement of the 1950s and �60s and also have  been applied to influence the conduct of multinational corporations.</p><p>Boyer \bwa-'ya\, Charles (b. Aug. 28, 1897, Figeac, France�d. Aug.  26, 1978, Phoenix, Ariz., U.S.) French-U.S. actor. After earning a phi�  losophy degree from the Sorbonne, he made his stage debut in Paris in  1920. He became a popular romantic leading man in French theatre and  film, and his rich, accented voice and suave manner made him an inter�  national star. His first successful U.S. film, Private Worlds (1935), was  followed by such films as Algiers (1938) and Gaslight (1944).</p><p>Boyle, Kay (b. Feb. 19, 1902, St. Paul, Minn., U.S.�d. Dec. 27, 1992,  Mill Valley, Calif.) U.S. writer. Boyle lived in Europe during the 1920s  and �30s. Later she served as a European correspondent for The New  Yorker (1946-53). Her writing is noted for its elegant style and consis�  tently leftist stance. Her novels, which include Plagued by the Nightin�  gale (1931) and Generation Without Farewell (1960), are less highly  regarded than her short stories, which include �The White Horses of  Vienna,� �Keep Your Pity,� and �Defeat.�</p><p>Boyle, Robert (b. Jan. 25, 1627, Lismore Castle, County Waterford,  Ire.�d. Dec. 31, 1691, London, Eng.) Irish-born English chemist and  natural philosopher. The son of Richard Boyle, the �Great Earl of Cork�  (1566-1643), he settled at Oxford in 1654 and, with his assistant Robert  Hooke, began his pioneering experiments on the properties of GASes,  including those expressed in Boyle�s law (see gas laws). He demonstrated  the physical characteristics of air, showing that it is necessary in com�  bustion, respiration, and sound transmission. In The Sceptical Chymist  (1661) he attacked Aristotle�s theory of the four elements (earth, air, fire,  and water), espousing a corpuscular view of matter that presaged the  modern theory of chemical elements. A founding member of the Royal  Society of London, he achieved great renown in his lifetime. His brother  Roger Boyle, earl of Orrery (1621-79), was a general under Oliver Crom�  well but eventually helped secure Ireland for Charles II.</p><p>Boyne, Battle of the (July 1690) Victory in Ireland for William III of  England, a Protestant, over the former king James II, a Roman Catholic.  James was attempting, with the help of the French and the Irish, to regain  his throne. In this battle, fought on the banks of the River Boyne, some  35,000 men under William defeated about 21,000 of James�s troops, forc�  ing James to flee the country. The battle is celebrated in Northern Ireland  as a victory for the Protestant cause.</p><p>boysenberry Very large bramble fruit, usually considered, along with  the loganberry and the youngberry, a variety of blackberry ( Rubus ursi-  nus). The dark, reddish-black fruit is especially valued for canning and  preserving. It is grown chiefly in the southern and southwestern U.S. and  on the Pacific Coast from southern California into Oregon. It was devel�  oped in the early 1920s by Rudolph Boysen (1895-1950) of Napa, Cal.</p><p>BP PLC formerly Anglo-Persian Oil Co., Ltd.,British Petro�  leum Co. PLC, and BP Amoco British petrochemical corporation.  Formed in 1909 as the Anglo-Persian Oil Co., Ltd., to finance an oil-field  concession granted by the Iranian government to William Knox D'Arcy, it  became one of the largest oil companies in the world, with oil fields and  refineries in Alaska and the North Sea. The British government was for  many years BP�s largest single stockholder, but by the late 1980s it had  turned over the company to private ownership. In 1987 BP consolidated  its U.S. interests by acquiring the Standard Oil Co. In 1998 it merged  with Amoco (formerly Standard Oil of Indiana) to form BP-Amoco. In  addition to oil and natural gas, it produces chemicals, plastics, and syn�  thetic fibres. Its headquarters are in London.</p><p>Brabant \'bra-bant\ Old duchy, northwestern Europe. Located in what  is now the southern part of The Netherlands and central and northern Bel�</p><p>gium, the region in the 9th century ad was part of the kingdom of Lothar-  ingia. In the late 12th century it became independent; it finally passed to  the house of Burgundy in 1430. Inherited by the Habsburgs in 1477, it  became a centre of culture and commerce (see Antwerp; Brussels). The  northern section of Brabant took part in a revolt from Spain, and in 1609  it was awarded to the United Provinces, while the southern section  remained part of Spanish (later Austrian) Netherlands. The northern sec�  tion now forms the Dutch province of North Brabant. The southern sec�  tion eventually became part of Belgium and is divided between the  provinces of Flemish Brabant and Walloon Brabant.</p><p>Bracciolini, Gian Francesco Poggio See Gian Francesco Poggio  Bracciolini</p><p>bracken or brake fern of the genus Pteridium, represented by a single  species (P. aquilinum). Twelve varieties are found throughout the world  in temperate and tropical regions. It is a noxious weed, with a perennial  black rootstock that creeps extensively underground. At intervals along  the rootstock, the plant sends up fronds that may reach a height of 15 ft  (5 m) or more. Though they die in autumn, the fronds often remain stand�  ing throughout winter, affording cover for wildlife in some areas. The  fronds are used for thatching and as fodder.</p><p>bracket fungus or shelf fungus Basidiomycete that forms shelflike  sporophores (spORE-producing organs).

Aug. 22, 1920, Waukegan, Ill., U.S.)  U.S. author. Bradbury is best known for highly imaginative science-fiction  stories and novels that blend social criticism with an awareness of the  hazards of runaway technology. The Martian Chronicles (1950; televi�  sion miniseries, 1980) is considered a science-fiction classic. His other  short-story collections include The Illustrated Man (1951; film, 1969),  The October Country (1955), I Sing the Body Electric! (1969; teleplay,  1981), and Quicker Than the Eye (1996); his novels include Fahrenheit  451 (1953; film, 1966), Dandelion Wine (1957; film, 1997), and Death Is  a Lonely Business (1985).</p><p>Braddock, Edward (b. 1695, Perthshire, Scot.�d. July 13, 1755,  Great Meadows, Pa.) British army commander in the French and Indian  War. After service in Europe, he arrived in Virginia in 1755 to command  British forces in North America against the French. He undertook an  expedition to attack the French-held Fort Duquesne (now Pittsburgh, Pa.);  his force, which included British regulars and provincial militiamen such  as George Washington, cut the first road across the Allegheny Mountains  and reached a point on the Monongahela River near the fort. There his  army of over 1,400 men was ambushed and defeated by a group of 254  French and 600 Indians, and he was mortally wounded in the ensuing rout.</p><p>Bradford City and metropolitan borough (pop., 2001: 467,668), West  Yorkshire, northern England. The manufacture of wool products was  important to its economy as early as 1311; the fine worsted trade began  in the late 17th century. By 1900 it emerged as the main wool-buying  centre for Yorkshire. The city remains a centre of the textile industry and  is the site of the University of Bradford.</p><p>Bradford, William (b.

A member of the Separatist movement within Puri�  tanism, in 1609 he left England and went to Holland seeking religious  freedom. Finding a lack of economic opportunity there, in 1620 he helped  organize an expedition of about 100 Pilgrims to the New World. He helped  draft the Mayflower Compact aboard the group�s ship, and he served as  governor of the Plymouth Colony for all but five years from 1621 to 1656.  He helped establish and foster the principles of self-government and reli�  gious freedom that characterized later American colonial government. His  descriptive journal provides a unique source of information on both the  voyage of the Mayflower and the challenges faced by the settlers.</p><p>Bradlee, Benjamin C(rowninshield) (b.

He learned to make  daguerreotypes from Samuel F.B. Morse. In 1844 he opened the first of two  studios in New York City and began photographing famous people  (including Daniel Webster, Edgar Allan Poe, and Henry Clay). In 1847  Brady opened a studio in Washington, D.C., and there created, copied,  and collected portraits of U.S. presidents. He achieved international fame  with A Gallery of Illustrious Americans (1850). In 1861 he set out to make  a complete record of the American Civil War with a staff of more than  20 photographers, including Timothy H. O'Sullivan and Alexander Gard�  ner.

Sept. 18, 1924, Oxford) British idealist philosopher. Influenced  by G.W.F. Hegel, he considered mind to be more fundamental than mat�  ter. In Ethical Studies (1876), he sought to expose confusions in utilitari�  anism. In The Principles of Logic (1883), he denounced the psychology  of the empiricists. His most ambitious work, Appearance and Reality  (1893), maintained that, though reality is spiritual, the thesis cannot be  demonstrated because of the fatally abstract nature of human thought.  Instead of ideas, which could not properly contain reality, he recom�  mended feeling, the immediacy of which could embrace the harmonious  nature of reality. He was the first English philosopher to be awarded the  Order of Merit. His brother was the eminent poetry critic A.C. Bradley</p><p>(1851-1935).</p><p>Bradley, Omar N(elson) (b.

In 1943 he commanded U.S. forces in the North Africa  Campaign and contributed directly to the fall of Tunisia to the Allies; he  then led the successful invasion of Sicily. As commander of the 1st Army,  he helped plan the invasion of France and took part in the Normandy  Campaign and the liberation of Paris. As commander of the 12th Army, the  largest U.S. force ever placed under one general, he oversaw European  operations until the German surrender. After the war he was appointed  head of veterans� affairs (1945-47) and chief of staff of the army (1948-  49). Admired by both officers and men, he was chosen the first chairman  of the Joint Chiefs of Staff (1949-53) and promoted to General of the  Army (1950).</p><p>Bradley, Thomas (b.

The son of a  sharecropper, he moved with his family to Los Angeles when he was seven  and endured poverty after his father abandoned the family. In 1940 he  began a 22-year tenure with the city�s police department, during which he  earned a law degree (1956) by attending night school. In 1963 he became  the city�s first African American council member, and in 1973 he was  elected one of the country�s first two African American mayors of a major  city (with Coleman Young of Detroit). During five terms as mayor, he  helped transform Los Angeles into a bustling business and trading centre,  overseeing massive growth and hosting the 1984 Olympic Games. He  retired in 1992 after the city was consumed by riots following the acquittal  of police officers in the beating of African American motorist Rodney King.</p><p>Bradman, Don (b.

The schools of Vedanta  differ in interpreting Brahman. The Advaita school defines Brahman as  categorically different from any phenomenon, conceiving it as an abso�  lute reality onto which human perceptions of differentiation are projected.  The Bhedabheda school maintains that Brahman is not different from the  world it produces. The Visistadvaita school holds that phenomenality is a  glorious manifestation of Brahman. The Dvaita school maintains that both  soul and matter are separate from and dependent on Brahman.</p><p>Brahman \'bra-mon\ or zebu \'ze-,bu\ Any of several varieties of  cattle that originated in India and were crossbred in the U.S. with  improved beef breeds to produce the hardy beef animal known as the  Santa Gertrudis. Similar blending in Latin America resulted in the breed  known as Indo-Brazil. The Brahman is characterized by a pronounced  hump over the shoulder and neck, horns that usually curve up and back,  and drooping ears. Gray is the prevalent colour, with deep shading in the  fore and rear quarters of the bull. A red strain has also been developed.</p><p>Brahman or Brahmin Any member of the highest of the four var-  nas, or social classes, in Hindu India. Their existence as a priestly caste  dates to the late Vedic period, and they have long been considered to be  of greater ritual purity than members of other castes and alone to be  capable of performing certain religious tasks, including preservation of  the collections of Vedic hymns. Because of their high prestige and tradi�  tion of education, they dominated Indian scholarship for centuries. As the  spiritual and intellectual elite, they advised the politically powerful war�  rior caste, and after Indian independence they supplied many heads of  state. They still retain traditional privileges, though these are no longer  legally sanctioned. Ritual purity is maintained through taboos, vegetari�  anism, and abstention from certain occupations.</p><p>Brahmana Vbra-mo-noN Any of a number of discourses on the Vedas  that explain their use in ritual sacrifices and the symbolism of the priests�  actions. Dating to 900-600 bc, they constitute the oldest historical sources  for Indian ritual. The Aitareya and Kausitaki Brahmana, compiled by fol�  lowers of the Rig Veda, include discussions of daily sacrifices, the sac�  rificial fire, new- and full-moon rites, and the rites for installation of kings.  The Pancavimsa, Sadvimsa, and Jaiminiya Brahmana discuss the �going  of the cows,� soma ceremonies, and atonements for mistakes in ritual. The  Satapatha Brahmana introduces elements of domestic ritual, and the  Gopatha Brahmana treats the priests� supervision of sacrifices.</p><p>Brahmaputra ^bra-mo-'pii-troX River River, Central and South Asia.  From its headsprings in Tibet (as the Zangbo River), it flows across south�  ern Tibet to break through the Himalayas in great gorges (where it is known  as the Dihang). It flows southwest through the Assam Valley and south  through Bangladesh (where it is known as the Jamuna). There it merges  with the Ganges (Ganga) to form the Ganges-Brahmaputra delta. About  1,800 mi (2,900 km) long, the river is an important source for irrigation  and transportation. Its upper course was long unknown, and its identity  with the Zangbo was only established by exploration in 1884-86.</p><p>Brahmo Samaj Vbra-mo-so-'majX Monotheistic movement within Hin�  duism, founded in Calcutta (now Kolkata) in 1828 by Ram Mohun Roy. It  rejected the authority of the Vedas and the doctrine of avatars, did not  insist on belief in karma or rebirth, denounced polytheism and the caste sys�  tem, and adopted some Christian practices. Roy�s intention was to reform  Hinduism from within, but his successor, Debendranath Tagore, rejected  Vedic authority. In 1866 Keshab Chunder Sen organized the more radi�  cal Brahmo Samaj of India, which campaigned for the education of  women and against child marriages. After Keshab nonetheless arranged  a marriage for his underage daughter, a third group, Sadharan Brahmo  Samaj, was formed in 1878. It gradually reverted to the teaching of the  Upanishads but continued the work of social reform. The movement,  always an elite group without significant popular following, lost force in  the 20th century.</p><p>Brahms, Johannes (b. May 7, 1833, Hamburg�d. April 3, 1897,  Vienna, Austria-Hungary) German composer. The son of a musician, he  became a piano prodigy. In 1853 he met the composer Robert Schumann  and his pianist wife, Clara (see Clara Schumann); Robert immediately  proclaimed him a genius, and Clara became the lifelong object of his  affections. In 1863 Brahms moved to Vienna, which would remain his  principal home until his death. He took several positions as choral and  orchestral conductor and performed as a soloist. The success of his Ger�  man Requiem (1868) gave him an international reputation; his first sym�  phony (1876) brought him even greater fame, and his violin concerto  (1879) and second piano concerto (1882) led many to acclaim him the  greatest living composer. His music complemented and counteracted the  rapid growth of Romantic individualism in the second half of the 19th  century. He was a traditionalist in the sense that he greatly revered the  subtlety and power of movement displayed by the Classical composers  Haydn, Mozart, and Beethoven. His orchestral works include four sym�  phonies (1876, 1877, 1883, 1885), two piano concertos (1858, 1881), a  violin concerto (1878), and a double concerto for violin and cello (1887).  His chamber music includes four string quartets, two string sextets, two  string quintets, three piano quartets, three piano trios, and violin, cello,  piano, and clarinet sonatas. He also wrote choral music and more than  250 lieder (see lied).</p><p>Braille \'bral\ Universal system of writing and printing for the blind.  The Frenchman Louis Braille invented the system in 1824. Characters  embossed on paper are read by passing the fingers lightly over the manu�  script. The system is based on a matrix of six dots arranged in two col�  umns of three. The 63 combinations possible in this framework stand for  letters, numbers, punctuation marks, and common words such as and and  the. A Braille code for English was not adopted until 1932.

Braille adapted a  method created by Charles Barbier to  develop his own simplified system.</p><p>brain Concentration of nerve tissue  in the front or upper end of an ani�  mal�s body. It handles sensory infor�  mation, controls motion, is vital to  instinctive acts, and in higher verte�  brates is the centre of learning. Ver�  tebrate brains consist of the</p><p>hindbrain (rhombencephalon), mid�  brain (mesencephalon), and fore�  brain (prosencephalon). The</p><p>hindbrain comprises the medulla  oblongata and the pons, which con�  nects the spinal cord with higher brain levels and transfers information  from the cerebral cortex to the cerebellum. The midbrain, a major sensory  integration centre in other vertebrates, serves primarily to link the hind�  brain and forebrain in mammals. Large nerve bundles connect the cer�  ebellum to the medulla, pons, and midbrain. In the forebrain the two  cerebral hemispheres are connected by a thick bundle of nerve fibres (cor�  pus callosum) and are divided by two deep grooves into four lobes (fron�  tal, parietal, temporal, and occipital). The cerebrum, the largest part of the  human brain, is involved with its more complex functions. Motor and  sensory nerve fibres from each hemisphere cross over in the medulla to  control the opposite side of the body.</p><p>brain death State of irreversible destruction of the brain. Before the  invention of life-support systems, brain death always led quickly to death  of the body. Ethical considerations are crucial to defining criteria for brain  death, which in most countries must be met before efforts to extend life  may be ended. Such criteria include deep coma with a known cause,  absence of any brainstem functions (e.g., spontaneous respiration, pupil  reactions, gag and cough reflexes), and exclusion of hypothermia, drugs,  and poison as causes. Electroencephalography is useful but not essential in  determining brain death. Organ donors must be declared brain-dead before  their organs may be removed for transplant. The question of when life  support can legally be ended has been the subject of numerous court cases.</p><p>brain laterality See laterality</p><p>Brain Trust Group of advisers to Franklin Roosevelt in his 1932 presi�  dential campaign.

They presented Roosevelt with analyses of national social and  economic problems and helped him devise public-policy solutions. The  group did not meet after Roosevelt became president, but members served  in government posts.

It  has been used by religious cults as well as by radical political groups such  as the Chinese Communists in 1949. The techniques of brainwashing  usually involve isolation from former associates and sources of informa�  tion; an exacting regimen calling for absolute obedience and humility;  strong social pressures and rewards for cooperation; physical and psycho�  logical punishments for noncooperation, including social ostracism and  criticism, deprivation of food, sleep, and social contacts, bondage, and  torture; and constant reinforcement. Its effects are sometimes reversed  through deprogramming, which combines confrontation and intensive  psychotherapy.</p><p>brake Device for decreasing the speed of a body or stopping its motion.  Most brakes act on rotating mechanical elements and absorb kinetic energy  mechanically, hydrodynamically, or electrically. Mechanical brakes are  the most common; they dissipate the kinetic energy as heat generated by  mechanical friction between a rotating drum or disk and a stationary fric�  tion element. A hydrodynamic (fluid) brake has a rotor (rotating element)  and a stator (stationary element).

The large cerebrum is divided  into two halves, or hemispheres, connected by the corpus callosum, a band of nerve  fibres. Two grooves divide the hemispheres into four lobes: frontal, temporal, pari�  etal, and occipital. Many nerve cells are found in the convoluted cerebrum's outer  surface, or cerebral cortex, which controls sensory and motor activities. The thala�  mus relays incoming sensory impulses from the spinal cord to the cortex. The hypo�  thalamus's many functions include control of breathing, blood flow, temperature  regulation, and emotions. The pituitary gland is attached to and regulated by the  hypothalamus. The midbrain relays signals between the forebrain and hindbrain.  The cerebellum, along with the cerebrum, plays a role in voluntary movement as  well as balance. The pons serves as a relay point linking the medulla oblongata,  midbrain, cerebellum, and cerebrum. The medulla, lying between the pons and the  spinal cord and continuous with both, plays a role in essential involuntary regula�  tory and reflexive responses (including breathing, swallowing, and heartbeat) and  relays signals between the spinal cord and other brain regions.</p><p>� MERRIAM-WEBSTER INC.</p><p>brake shoe</p><p>piston</p><p>caliper housing</p><p>brake</p><p>piston</p><p>boot</p><p>hub</p><p>disc (rotor)</p><p>piston seal</p><p>A disc brake assembly.

Originally  a cabinetmaker, Bramah in 1784 devised a pick-proof lock, which defied  all efforts for 67 years. Since the success of his locks depended on their  complexity, they could be produced in quantity only after the creation of  a set of well-designed and precisely engineered machine tools, for which  he hired a brilliant young blacksmith, Henry Maudslay. Their prototype  machines were essential to the founding of the machine-tool industry. Bra�  mah�s hydraulic press found many industrial uses and led to the devel�  opment of hydraulic machinery.</p><p>Bramante \bra-'man-ta\, Donato (b. 1444, probably at Monte Asdru-  valdo, Duchy of Urbino�d. April  11, 1514, Rome) Italian architect and  perspectivist painter. The son of a  farmer, he was working as a painter  by 1477. His early architectural  works included the church of Santa  Maria presso San Satiro (c. 1480), in  which the choir is painted in perspec�  tive to give an illusion of a much  larger space. In 1499 he went to  Rome, where he spent the rest of his  life. His Tempietto was the first mas�  terpiece of the High Renaissance.</p><p>Under the patronage of Pope Julius II,  he drew up plans for the immense  Belvedere courtyard in the Vatican  (begun c. 1505) and the new St.</p><p>Peter's Basilica (begun 1506), his  greatest work. These ambitious  projects were far from complete at  the time of his death. Despite the  grandiose scale of the St. Peter�s  undertaking, Bramante continued to work on other projects and played an  important role in Julius II�s plans for rebuilding Rome.</p><p>bramble Any plant of the genus Rubus (rose family), consisting of usu�  ally prickly shrubs, including raspberries and blackberries.

Its industries include flower grow�  ing, tanning, lumbering, and the manufacture of automobiles, shoes, sta�  tionery, furniture, and optical equipment.</p><p>Bran Vbran\ In Celtic religion, a gigantic deity described in the Mabino-  gion as king of Britain. He was so large that he and his court lived in a  tent rather than a house. When Bran was mortally wounded, he asked his  companions to cut off his head and keep it with them, telling them it would  provide entertainment and allow them to forget their sorrows. His com�  panions passed 80 joyous years, eventually following his instructions and  burying the head on the White Mount in London, where it protected  England from invaders until it was finally unearthed.</p><p>bran Edible broken seed coat, or protective outer layer, of wheat, rye,  or other cereal grain, separated from the kernel. In flour processing, it is  normally removed from the ground kernels by sifting them in a rotating,  meshed, cylindrical frame; whole-grain flours retain the bran. Wheat bran,  the most widely processed, contains 16% protein, 11% natural fibre, and  50% carbohydrate. Most bran is coarsely ground for stock feed. In a more  refined form, it is used in breakfast cereal, breads, and muffins for its value  to the human digestive system as roughage.</p><p>Branch Davidians Religious sect that believes in the imminent return  of Jesus Christ. It was founded in 1935 near Waco, Texas, by Victor  Houteff as a breakaway group from the Seventh-Day Adventists. Under  the leadership of Vernon Howell, a charismatic and apocalyptic preacher  who would take the name David Koresh (1959-1993), it stockpiled weap�  ons at its compound, where some 130 followers were living by 1993. That</p><p>year, after a shoot-out in which four federal agents were killed, federal  law-enforcement agencies besieged the compound for 51 days. The stand�  off ended, at the orders of Attorney General Janet Reno, in a conflagra�  tion in which some 80 members died, including several children and  Koresh himself. Intense controversy about the precise circumstances and  the necessity of the final assault led to a Congressional investigation,  which in 2000 exonerated federal agents.</p><p>Brancusi, Constantin (b.

He became adept at  carving wooden farm implements as a child and later studied in Bucharest  and Munich and at the Ecole des Beaux-Arts in Paris, having walked most  of the way from Munich. He first exhibited in Paris in 1906. In 1908 he  executed Sleeping Muse , influenced by Auguste Rodin, and The Kiss, his  first truly original work. He developed a geometric style that became his  hallmark, reducing natural forms to an abstract simplicity. He exhibited  five works, including Mademoiselle Pogany, in the 1913 Armory Show.  One of his favourite themes was a bird in flight; his most famous treatment  was the celebrated polished-bronze Bird in Space (1919). Through numer�  ous exhibitions in the U.S. and Europe, he achieved great fame and suc�  cess, and he is regarded as a pioneer of modern abstract sculpture.</p><p>Brandeis Vbran-.dlsV, Louis (Dembitz) (b.

The son of  Bohemian Jewish immigrants, he  attended schools in Kentucky and  Germany before obtaining his law  degree from Harvard (1877). As a  lawyer in Boston (1877-1916), he  was known as �the people�s attor�  ney� for his defense of the constitu�  tionality of several state hours-and-  wages laws, his devising of a  savings-bank life-insurance plan for  working people, and his efforts to  strengthen the government�s anti�  trust power. His work influenced  passage in 1914 of the Clayton Anti-  Trust Act and the Federal Trade  Commission Act. He also developed  what came to be called the �Brandeis  brief,� in which economic and socio�  logical data, historical material, and  expert opinion are marshaled to support a legal argument. Appointed to  the Supreme Court of the United States (1916), he was noted for his devo�  tion to freedom OF speech. Many of his minority opinions, in which he was  often aligned with Oliver Wendell Holmes, Jr., later were accepted by the  court in the New Deal era. His appointment as the first Jewish justice was  vigorously opposed by some business interests and anti-Semitic groups.  He served until 1939. Brandeis University is named for him.</p><p>Brandenburg Historical region and province of Prussia. The earliest  Germanic inhabitants were replaced by Slavic Wends, who in turn were  overcome in the 12th century by Albert the Bear, margrave of Branden�  burg. It became one of the seven electorates of the Holy Roman Empire in  1356. Under the elector Frederick William (1640-88), Brandenburg-Prussia  grew to be a leading power. It became a province of Prussia in 1815 and  remained such after the unification of Germany (1871) and until the end  of World War II. After the war, the eastern portion became part of Poland  and the western portion part of East Germany. After Germany�s reunifi�  cation in 1990, the western part became a German state.

On top was the �Quadriga of Victory,�  a statue of a chariot drawn by four horses. Heavily damaged in World  War II, the gate was restored in 1957-58. From 1961 to 1989 the Berlin  Wall shut off access to it for both eastern and western Germans; the gate  was reopened in 1989 with the reunification of East and West Berlin.</p><p>Brandes Vbran-d9s\, Georg (Morris Cohen) (b.

He  returned to England in 1931 and took up photojournalism, documenting  English industrial workers in the 1930s and covering the home front dur�  ing World War II. His work reveals the influence of Eugene Atget, Bras-  SAi, and Henri Cartier-Bresson.

As a young Social Democrat,  he fled to Norway to avoid arrest  after the rise of the Nazis in the  1930s. There he assumed the name  Willy Brandt and worked as a jour�  nalist. Returning to Germany after  World War II, he was elected to par�  liament in 1949 and became mayor  of West Berlin (1957-66), a post in  which he achieved world fame. He  led a coalition government as chan�  cellor of the Federal Republic of  Germany (1969-74). As chancellor,  he improved relations with East Ger�  many, other communist nations in  eastern Europe, and the Soviet Union  and helped strengthen the European  Economic Community. For these  efforts he received the Nobel Prize for Peace in 1971. He remained the  leader of the Social Democratic Party until 1987.</p><p>brandy Alcoholic beverage distilled from wine or a fermented fruit mash.

May 13, 1882, Argenteuil, France�d.  Aug. 31, 1963, Paris) French painter. He studied painting in Le Havre,  then in Paris at a private academy and briefly at the Ecole des Beaux-  Arts. Though his earliest works were influenced by Impressionism, his  first important paintings (1905-07) were in the style of Fauvism pioneered  by Andre Derain and Henri Matisse; in 1907 he exhibited and sold six of  these paintings at the Salon des Independants. Abandoning Fauvism in  1907, he invented with Pablo Picasso the revolutionary new style known  as Cubism. He painted mostly still lifes featuring geometric shapes and  low-key colour harmonies. In 1912 he introduced the collage, or papier  colie (pasted-paper picture), by attaching three pieces of wallpaper to the  drawing Fruit Dish and Glass. By the 1920s he was a prosperous, well-  established modern master. In 1923 and 1925 he designed stage sets for  Sergey Diaghilev�s Ballets Russes. He enjoyed a long and prestigious  career; in his later years he was honoured with important exhibitions  throughout the world. In 1961 he became the first living artist to have his  works exhibited in the Louvre.</p><p>Bras d'Or \bra-'dor\ Lake Salt lake, Nova Scotia, Canada.

Brass was first used c. 1200 bc in the Near East, then extensively in  China after 220 bc, and soon thereafter by the Romans. In ancient docu�  ments, including the Bible, the term brass is often used to denote bronze  (copper/tin alloy). The malleability of brass depends on its zinc content;  brasses with more than 45% zinc are not workable. Alpha brasses con�  tain less than 40% zinc; beta brasses (40-45% zinc) are less ductile than  alpha brasses but stronger. A third group includes brasses with additional  elements.

A  saleswoman in the shop of Hitler�s  photographer, she became Hitler�s  mistress in the 1930s, living first in a  house he provided in Munich, then at  his chalet in Berchtesgaden. He never  allowed her to be seen in public with  him, and she had no influence on his  political life. In April 1945 she joined  him in Berlin, against his orders, as  the Allied Powers were closing in on  the capital. In recognition of her loy�  alty, he married her in a civil cer�  emony in the Chancellery bunker on  April 29. The next day Eva Hitler  ended her life by taking poison; her  husband shot himself.

June 16, 1977, Alexandria, Va.,  U.S.) German-bom U.S. rocket engineer. Born into an aristocratic fam�  ily, he received his doctorate from the University of Berlin. In 1936 he  became technical director of the new military development facility at  Peenemiinde, an essential centre for the rearmament of Nazi Germany,  forbidden by the Versailles accords. Liquid-fueled rocket aircraft and jet-  assisted takeoffs were successfully demonstrated there, and the V-2 long-  range ballistic missile and the Wasserfall supersonic antiaircraft missile  were developed. By 1944 the sophistication of the rockets and missiles  being tested at Peenemiinde was many years ahead of that of any other  country. After World War II he and his team surrendered to the U.S.; they  were immediately set to work on guided missiles by the U.S. Army, and  in 1952 he became technical director (later chief) of the Army�s ballistic  weapon program. Under his leadership, the Redstone, Jupiter-C, Juno, and  Pershing missiles were developed. In 1958 he and his group launched the  first U.S. satellite, Explorer 1 . After NASA was formed, von Braun led the  development of some of the large Saturn space launch vehicles; the engi�  neering success of each of the Saturn class of space boosters remains  unmatched in rocket history.</p><p>Braunschweig Vbraun-,shfik\ English Brunswick Administrative  district, Lower Saxony, Germany.

Area: 3,287,612 sq mi (8,514,877 sq km). Popu�  lation (2005 est.): 184,016,000. Capital: Brasilia. Most Brazilians are of  European or mixed (Indian-European, European-African) ancestry. Bra�  zil�s ethnic groups have intermixed since the earliest days of its colonial  history; Indian peoples who have experienced no mixing with immigrants  are restricted to the most remote parts of the Amazon River basin. Lan�  guage: Portuguese (official). Religions: Christianity (predominantly  Roman Catholic; also Protestant); also traditional beliefs. Currency: real.  Brazil may be divided into many regions, but the Amazon lowlands and  the Brazilian Highlands (often called the Central Highlands or Central  Plateau) dominate the landscape. The highlands, a plateau with an aver�  age elevation of 3,300 ft (1,000 m), are primarily in the southeast, while  the Amazon lowlands, with elevations below 800 ft (250 m), are in the  north. The Amazon River basin, with its more than 1,000 known tributar�  ies, occupies nearly half of the country�s total area. Brazil�s other rivers  include the Sao Francisco, Parnafba, Paraguay, Alto Parana, and Uruguay.  Except for the islands of Marajo and Caviana at the mouth of the Ama�  zon and Maraca to the north, there are no large islands along the roughly  4,600 mi (7,400 km) of Brazil�s Atlantic Ocean coast.

It is a federal republic with  two legislative houses; its chief of  state and government is the presi�  dent. Little is known about Brazil�s  early indigenous inhabitants.</p><p>Though the area was theoretically  allotted to Portugal by the 1494  Treaty of Tordesillas, it was not for�  mally claimed by discovery until  Portuguese navigator Pedro Alvares  Cabral accidentally touched land in  1500. It was first settled by the Por�  tuguese in the early 1530s on the  northeastern coast and at Sao Vicen�  te (near modem Sao Paulo); the  French and Dutch created small  settlements over the next century. A  viceroyalty was established in 1640,  and Rio de Janeiro became the capi�  tal in 1763. In 1808 Brazil became  the refuge and seat of the govern�  ment of John VI of Portugal when  Napoleon I invaded Portugal; ulti�  mately the Kingdom of Portugal,</p><p>Brazil, and Algarve was proclaimed,  and John ruled from Brazil (1815�</p><p>21).

Brazil nuts are high in  fat and protein and taste somewhat like almond or coconut. The tree grows  wild in stands in the Amazon River basin, reaching heights of 150 ft (45  m) or more.</p><p>brazing Process for joining two pieces of metal by applying heat and  adding a filler metal. The filler, which has a lower melting point than the  metals to be joined, is either pre-placed or fed into the joint as the parts  are heated. In brazing parts with small clearances, the filler is able to flow  into the joint by capillarity. The temperature of the molten filler in braz�  ing exceeds 800�F (430�C). In soldering, a related process, the filler metal  remains below that temperature. Brazed joints are usually stronger than  soldered joints. Most metals can be brazed, and the range of available  brazing alloys has increased as new alloys and new service requirements  are introduced. Brazed joints are highly reliable and are used extensively  on rockets, jet engines, and aircraft parts.

In 1875-78 he  explored the Ogooue River (in present-day Gabon). Racing his British-  U.S. counterpart, Henry Morton Stanley, Brazza was sent to explore the  Congo River region. There he founded the French (Middle) Congo,  explored Gabon, and founded the city of Brazzaville (1883), adding some  200,000 sq mi (500,000 sq km) to the French colonial empire.

It is made of flour or meal that is moistened  into a dough, kneaded, and usually leavened with yeast. A major food since  prehistoric times, bread has been made worldwide in various forms using  a variety of ingredients and methods. Flat, unleavened bread, the earliest</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>breadfruit &#x25BA; Bremen I 271</p><p>form, is still eaten in the Middle East, Asia, and Africa. The principal  grains used in such breads are wheat, barley, millet, buckwheat, rye, and  corn. Raised bread, common in Europe and the U.S., is usually made of  wheat or rye. Both contain the elastic protein substance gluten, which  traps gas produced by fermentation during leavening, helping the bread to  rise. While the simplest breads contain only flour, water, and yeast, other  common ingredients are milk, shortening (fats, butter, oils), salt, eggs, and  sugar. Bread is a source of complex carbohydrates and B vitamins (see  vitamin B complex); whole-wheat bread contains more protein, vitamins,  minerals, and fibre than white-flour bread.

Treculia africana, native to tropi�  cal Africa, is less important as a food crop. Cultivated in the Malay Archi�  pelago (where it is thought to be indigenous) since remote antiquity, the  breadfruit was spread throughout the tropical South Pacific in prehistoric  times. It is high in starch and is seldom eaten raw. Unable to tolerate frost,  the tree has not been successfully grown in the U.S., even in southern�  most Florida.

He  practiced labour law in New Jersey until 1949, when he was appointed  to the state Superior Court. He rose through the ranks of the New Jersey  courts, where he was noted for his administrative skill. Although a Demo�  crat, he was named to the Supreme Court of the United States by Republi�  can Pres. Dwight D. Eisenhower in 1956. He came to be regarded as one  of the most influential jurists in its history. A liberal constructionist and  an articulate defender of the Bill of Rights, he is perhaps best remembered  for his role in a series of obscenity cases, beginning with Roth v. United  States (1957), many of which broadened the protection accorded to pub�  lishers while seeking to balance individual freedoms with the interests of  the community. In New York Times v. Sullivan (1964), he wrote that even  false statements about public officials are protected under the 1st and 14th  Amendments unless �actual malice� can be demonstrated. He also wrote  the majority opinion in Baker v. Carr (1962). He opposed capital punish�  ment and supported abortion rights, affirmative action, and school deseg�  regation.

Sept. 28, 1966, Paris) French writer, critic, and editor. In 1919 he helped  found the Dada magazine Litterature. Influenced by psychiatry and the  Symbolist movement, he wrote poetry using the automatic-writing tech�  nique. In 1924 his Manifeste du surrealisme provided a definition of Sur�  realism, of which he was the chief promoter. In the 1930s he joined and  then broke with the Communist Party; in 1938 he founded the Federation  de l�Art Revolutionnaire Independant with Leon Trotsky in Mexico. He  spent World War II in the U.S. and returned to France in 1946. His Poemes  appeared in 1948.

In World War II he was a  political commissar in the Red Army and rose to major general (1943).  In the 1950s he supported Nikita Khrushchev and became a member of the  Politburo, though in 1964 he was the leader of a coalition that ousted  Khrushchev, and soon he emerged as general secretary of the party (1966-  82). He developed the Brezhnev Doctrine, which asserted the right of  Soviet intervention in such Warsaw Pact countries as Czechoslovakia</p><p>(1968). In the 1970s he attempted to normalize relations with the West  and to promote detente with the U.S. He was made marshal of the Soviet  Union in 1976 and chairman of the Presidium of the Supreme Soviet in  1977, becoming the first to hold the leadership of both the party and the  state. He greatly expanded the Soviet Union�s military-industrial complex,  but in so doing he deprived the rest of the Soviet economy.

Between 1909 and 1929 he served 11 times as premier of  France, and he held 26 ministerial posts between 1906 and 1932. His  achievements included the Pact of Locarno and the Kellogg-Briand Pact.  For his efforts for international cooperation, the League of Nations, and  world peace, he shared the 1926 Nobel Prize for Peace with Gustav Stre-  SEMANN.</p><p>bribery Crime of giving a benefit (e.g., money) in order to influence the  judgment or conduct of a person in a position of trust (e.g., an official or  witness). Accepting a bribe also constitutes a crime. Bribery is typically  punishable as a felony (see felony and misdemeanour). In any charge of  bribery, some element of �corrupt purpose� must be implied or proved.  Thus, in the absence of a complete statutory prohibition on the granting of  favours to a public official, a gift is not a bribe unless it is given with some  intent to influence the recipient�s official behaviour.

He graduated from Ohio  State University (1916), then practiced law and later served as the state�s  attorney general (1933-37). Elected governor, he became the first Repub�  lican to win three consecutive terms. He was Thomas Dewey�s running mate  in the 1944 presidential race. As a U.S. senator, he led efforts to curb the  president�s power in foreign affairs.

Bridge construction has always presented civil  engineering with its greatest challenges. The simplest bridge is the beam  (or girder) bridge, consisting of straight, rigid beams of steel or concrete  placed across a span. Ancient Roman bridges are famous for their rounded  arch form, which permitted spans much longer than those of stone beams  and were more durable than wood. A modem version of the arch bridge  might have a tmssed arch anchored to the abutments and a deck hanging  from the arch by vertical cables. Suspension bridges (e.g., Brooklyn Bridge,  Golden Gate Bridge) are capable of spanning great distances; their main  support members are cables composed of thousands of strands of wire  supported by two towers and anchored at each end, and the deck is sus�  pended by vertical cables hung from the main cables. In cable-stayed  bridges, cables fan out and down from a central tower to various points  on the deck; variations of this design have resulted in bridges of striking  design and very long span. Other bridges include the truss bridge, popu�  lar (e.g., for railroad bridges) because it uses a relatively small amount  of material to carry large loads, and the cantilever bridge, typically made  with three spans, with the outer spans anchored down at the shore and the  central span resting on the cantilevered arms.</p><p>ARCH BRIDGE</p><p>pier trussed arch arch upper chord portal frame</p><p>BEAM BRIDGE</p><p>overpass continuous beam parapet</p><p>deck underpass pier</p><p>anchorage</p><p>side span</p><p>SUSPENSION BRIDGE</p><p>suspension suspender</p><p>approach</p><p>ramp</p><p>deck centre span</p><p>tower abutment</p><p>Three common types of bridge design.</p><p>� MERRIAM-WEBSTER INC.</p><p>bridge Card game similar to whist. Bridge is any one of several games,  including games such as auction bridge and contract bridge, which retain  the essential features of whist: Four players participate, two against two  in partnership. They play with a 52-card pack, all cards of which are dealt  face downward one at a time, clockwise. When play begins, the object is  to win tricks, consisting of one card from each player in rotation. The  players must, if able, contribute a card of the suit led, and the trick is won  by the highest card. All tricks taken in excess of the first six tricks are  known as odd tricks. Before play begins, a suit may be designated the  trump suit, in which case any card in it beats any card of the other suits.  In all types of bridge a certain number points are needed to win a game,  and two games won by the same team allows them to win the rubber.</p><p>Bridgeport City (pop., 2000: 139,529), southwestern Connecticut, U.S.  Located on Long Island Sound at the mouth of the Pequonnock River, it  was settled in 1639. Its earlier names included Newfield and Stratfield;  Bridgeport was chosen in 1800. P.T. Barnum was once its mayor, and his  star attraction �Tom Thumb� was bom there. The city evolved into an  industrial centre following the arrival of the railroad in 1840. In the late  20th century, its industrial base eroded, causing financial problems for the  city.</p><p>Bridger, Jim orig. James Bridger (b. March 17, 1804, Richmond,  Va., U.S.�d.

He was  apparently the first white man to visit the Great Salt Lake (1824) and  among the first to explore Wyoming�s Yellowstone River region. In 1843  he established Fort Bridger, Wyo., as a fur-trading post on the Oregon  Trail. After the 1850s he worked as a government scout. He became leg�  endary for his knowledge of the territory and its Indian inhabitants.</p><p>Bridges, Calvin Blackman (b. Jan. 11, 1889, Schuyler Falls, N.Y.,  U.S.�d.

He entered  Columbia University in 1909 and assisted Thomas Hunt Morgan in design�  ing experiments using Drosophila that showed that variations in the insect  could be traced to observable changes in its genes. These experiments led  to the construction of gene maps and proved the chromosome theory of  heredity. In 1928 Bridges and Morgan moved to California Institute of  Technology, where Bridges continued gene mapping and later discovered  an important class of drosophila mutants caused by gene duplications.</p><p>Bridges, Harry orig.

He arrived in the  U.S. as a seaman in 1920, and he soon settled in San Francisco and  became active in the local branch of the International Longshoremen�s  Association (ILA). In 1937 he led the Pacific Coast division out of the  ILA and reconstituted it as the International Longshoremen�s and Ware�  housemen�s Union (ILWU), affiliated with the CIO (see AFL-CIO). His  aggressive labour tactics and Communist Party connections led the CIO  to expel the ILWU in 1950 during a purge of allegedly communist-  dominated unions, and opponents tried unsuccessfully to have Bridges  deported.

Its leaves are needlelike  and its flowers almost white.</p><p>brig Two-masted sailing ship with square rigging on both masts. Brigs  were both naval and mercantile vessels. As merchantmen, they often fol�  lowed coastal trading routes, but ocean voyages were not uncommon, and  some were even used for whaling and sealing. Naval brigs carried 10-20  guns on a single deck. In the 18th�19th century, they served as couriers  for battle fleets and as training vessels for cadets. Brigs of the early U.S.  Navy won distinction on the Great Lakes in the War of 1812. Because  square rigging required a large crew, merchant brigs became uneconomi�  cal, and in the 19th century they began to give way to vessels such as the  schooner and the bark.</p><p>brigade \bri-'gad\ Military unit commanded by a brigadier general or a  colonel and composed of two or more subordinate units, such as regiments  or battalions.

In the chronic stage a small, shriv�  eled, scarred kidney cannot filter nitrogen compounds from the blood,  causing uremia. Treatment focuses on symptom relief.</p><p>Brighton Town (pop., 1995 est.: 143,000), southern England. Lying on  the English Channel south of London, it was for several centuries a small  fishing village, but it gained popularity in the late 18th century when the  prince of Wales (later George IV) made the first of his many visits.

Lying at the confluence of the Rivers Avon and Frome, the city  received its first charter in 1155. Long a centre of commerce, it was the  point of departure in 1497 of John Cabot in his search for a route to Asia.  During the 17th�18th centuries it prospered in the triangular trade (rum,  molasses, and slaves) between West Africa and the West Indian and  American plantation colonies. Though Bristol suffered a decline in trade  in the early 19th century, it soon rebounded with the coming of the rail�  way. It suffered severe damage from bombing in World War II but was  rebuilt. Today it is an important shipping centre, especially for oil and  food products.</p><p>Bristol Channel Inlet of the Atlantic Ocean, southwestern England. It  extends about 85 mi (135 km) between southern Wales and southwestern  England, ranging from 5 to 43 mi (8-69 km) wide.

The province has an  area of 364,764 sq mi (944,735 sq km), and its capital is Victoria. The  area was inhabited by indigenous peoples, including Coast Salish,  Nootka, Kwakiutl, and Haida. It was visited in 1578 by Sir Francis Drake  and in 1778 by Capt. James Cook, who was searching for the Northwest  Passage. Capt. George Vancouver surveyed the coast (1792-94), and over�  land expeditions were made by several explorers, including Alexander  Mackenzie and Simon Fraser. The British and Americans contended over  Vancouver Island for years, until it was recognized as British and made a  crown colony in 1849. The mainland became the colony of British Colum�  bia in 1858; with the colony of Vancouver Island, it joined Canada in 1871  as the province of British Columbia.

Brit�  ish penetration of the area began at Zanzibar in the late 19th century. In  1888 the British East Africa Co. established claims to territory in what is  now Kenya. British protectorates were subsequently established over the  sultanate of Zanzibar and the kingdom of BUganda (see Uganda). In 1919  Britain was awarded the former German territory of Tanganyika as a  League of Nations mandate. All these territories achieved political inde�  pendence in the 1960s.</p><p>British Empire Worldwide system of dependencies�colonies, protec�  torates, and other territories�that over a span of three centuries came  under the British government. Territorial acquisition began in the early  17th century with a group of settlements in North America and West Indian,  South Asian, and African trading posts founded by private individuals and  trading companies. In the 18th century the British took Gibraltar, estab�  lished colonies along the Atlantic seacoast of North America and in the Car�  ibbean Sea, and began to add territory in India. With its victory in the  French and Indian War (1763), the empire secured Canada and the eastern  Mississippi Valley and gained supremacy in India. From the late 18th cen�  tury it began to build power in Malaya and acquired the Cape of Good  Hope, Ceylon (see Sri Lanka), and Malta. The British settled Australia in  1788 and subsequently New Zealand. Aden was secured in 1839, and Hong  Kong in 1841. Britain went on to control the Suez Canal (1875-1956). In  the 19th-century European partition of Africa, Britain acquired Nigeria,  Egypt, the territories that would become British East Africa, and part of what  would become the Union (later Republic) of South Africa. After World War  I, Britain secured mandates to German East Africa, part of the Cameroons,  part of Togo, German South-West Africa, Mesopotamia, Palestine, and part  of the German Pacific islands. Britain gradually evolved a system of self-  government for some colonies after the U.S. gained independence, as set  forth in Lord Durham�s report of 1839. Dominion status was given to  Canada (1867), Australia (1901), New Zealand (1907), the Union of South  Africa (1910), and the Irish Free State (1921). Britain declared war on Ger�  many in 1914 on behalf of the entire empire; after World War I the domin�  ions signed the peace treaties themselves and joined the League of Nations  as independent states. In 1931 the Statute of Westminster recognized them  as independent countries �within the British Empire,� referring to the  �British Commonwealth of Nations,� and from 1949, the Commonwealth  of Nations. The British Empire, therefore, developed into the Common�  wealth in the mid-20th century, as former British dependencies obtained  sovereignty but retained ties to the United Kingdom.</p><p>British Expeditionary Force (BEF) Home-based regular British  army forces sent to northern France at the start of World Wars I and II to  support the French armies. Britain wished to help France in case of a Ger�  man attack, and the BEF was created in 1908 to ensure that British forces  would be trained and ready to respond quickly. It consisted of six infan�  try divisions and one cavalry division. Five divisions sent to France at the  outbreak of World War I sustained heavy losses and were succeeded by  vast British armies. Divisions sent to France early in World War II (1939)  returned to England when France fell the next year.</p><p>British Guiana See Guyana  British Honduras See Belize</p><p>British Invasion Musical movement.

In 1881 the natural-history collections were transferred to another build�  ing to form the Natural History Museum, and in 1973 the library collec�  tions were consolidated to form the British Library. Among the museum�s  most famous holdings are the Elgin Marbles, the Rosetta Stone, the Port�  land Vase, and Chinese ceramics.

Known in ancient  times as Armorica, it comprised the coastal area between the Seine and  Loire rivers. Inhabited by Celts, it was conquered by Julius Caesar and  organized as a Roman province. Invaded in the 5th century ad by Brit�  ons (Celtic people from Britain), the extreme northwestern part was there�  after called Brittany. Subdued by Clovis I, it was never effectively part of  the Merovingian or Carolingian kingdom. France claimed Brittany in the  13th century, but it remained a separate state until the 15th century. It was  formally incorporated into France in 1532 and had province status until  the French Revolution. Roughly coextensive with but smaller than the his�  torical region, the current administrative region of Brittany (pop., 2004  est.: 3,011,000) covers 10,505 sq mi (27,209 sq km).

His auspicious  Variations on a Theme of Frank  Bridge (1937), for string orchestra,  won him international acclaim. In  1945 his opera Peter Grimes estab�  lished him as a leading opera com�  poser. In 1948 he cofounded the  Aldeburgh Festival, which became  one of the most important English  music festivals and the centre of  Britten�s musical activities. His  operas include The Rape of Lucretia  (1946), The Turn of the Screw  (1954), and Death in Venice (1973);  they are admired for their skillful set�  ting of English words and their orchestral interludes, as well as for their  dramatic aptness and depth of psychological characterization. His large</p><p>choral work War Requiem (1961) was greatly acclaimed. His best-known  orchestral piece is The Young Person�s Guide to the Orchestra (1946).

They may also allow multiple data channels to  be broadcast simultaneously.</p><p>broadcasting Transmission of sound or images by radio or television.  After Guglielmo Marconi�s discovery of wireless broadcasting in 1901,  radio broadcasting was undertaken by amateurs. The first U.S. commer�  cial radio station, KDKA of Pittsburgh, began operation in 1920. The  number of stations increased rapidly, as did the formation of national radio  networks. To avoid radio monopolies, Congress passed the Radio Act of  1927, which created the Federal Communications Commission to over�  see broadcast operations. In the 1930s and �40s, the �golden age of radio,�  innovations in broadcast techniques and programming made radio the  most popular entertainment medium. Television broadcasting began in  Germany and Britain in the 1930s. After World War II, the U.S. took the  lead, and television stations soon overshadowed radio networks. Color  television broadcasts began in 1954 and became widespread in the 1960s.  By the 1980s, satellite transmission of live television further expanded  the field of broadcasting.

It is named for the avenue  that runs through the Times Square area in central Manhattan, where most  of the larger theatres are located. Broadway attracted theatre producers  and impresarios from the mid-19th century. The number and size of the  theatres grew with New York�s increasing prosperity, and by the 1890s  the brightly lit street was called �the Great White Way.� By 1925, the  height of theatrical activity in New York, about 80 theatres were located  on or near Broadway; by 1980 only about 40 remained. In the 1990s the  revitalization of the seedy Times Square neighbourhood attracted larger  audiences, though high production costs limited the viability of serious  plays in Broadway theatres, which often chose to mount big musicals and  other crowd-pleasing commercial ventures.

More than 40 species are found in the U.S.; about half are native grasses.  Rescue grass ( B. catharticus), a forage and pasture grass, and smooth  brome ( B. inermis ), a forage plant and soil binder, are the economically  important species. Downy brome or cheatgrass (B. tectorum), ripgut grass  (B. diandrus ), and foxtail brome ( B . rubens) are dangerous to grazing ani�  mals; their spines can puncture the animals� eyes, mouths, and intestines,  leading to infection and possible death.</p><p>bromeliad \br6-'me-le-,ad\ Any of the flowering plants of the order  Bromeliales, containing a single family, Bromeliaceae, with almost 2,600  species.

Many bromeliads are short-stemmed epiphytes.  Many species bear flowers in a long spike, with coloured bracts below or  along the spike. Most have fleshy fruit, but some produce dry pods. Span�  ish moss and the edible fruit of the pineapple are the major economic prod�  ucts of the family. The leaves of some species contain fibres that are made  into rope, fabric, and netting.

It is obtained from seawater and brines or salt beds.  Extremely irritating and toxic, bromine is a strong oxidizing agent (see  oxidation-reduction). Its compounds, in which it may have valence 1, 3, 5,  or 7, have many uses, including as petroleum additives (ethylene dibro�  mide), in photographic emulsions (silver bromide), as sedatives, and in  flour (potassium bromate).</p><p>bronchiectasis V.braq-ke-'ek-to-sosV Abnormal expansion of bronchi in  the lungs. It usually results when preexisting lung disease causes bron�  chial inflammation and obstruction. Bronchial wall fibres degenerate, and  bronchi become dilated or paralyzed, preventing removal of secretions,  which stagnate. Infection spreads and intensifies. Evidence of the disease  includes presence of infective agents, excess mucous secretions, and, in  children, fatigue and growth retardation. Complications include recurrent  pneumonia, lung abscesses, spitting up blood, and, in chronic cases, toe  and finger clubbing. Treatment involves frequent, long-term drainage or  (if the disease is on one side only) surgical removal of affected lung seg�  ments and antibiotics.</p><p>bronchitis \braq-'kI-tos\ Inflammation in the bronchi of the lungs.  Microbes and foreign matter that have entered the airways cause inflam�  mation of the bronchi and stimulate excess secretion of mucus. Symp�  toms include a productive cough and a sensation of chest congestion.  Long-term repetitive injury, as from smoking, may lead to chronic bron�  chitis, in which severe, irreversible damage leaves the lungs open to infec�  tion and fibrosis. Smoking-related chronic bronchitis often occurs in  association with emphysema (together called chronic obstructive pulmonary  disease). Treatment includes drugs to dilate the bronchi and promote  coughing, antibiotics, and lifestyle adaptations (e.g., quitting smoking).</p><p>Bronte Vbran-te\ sisters Family of English writers.

Emily (Jane) Bronte (July 30, 1818-Dec.  19, 1848) was perhaps the greatest writer of the three. Poems by Currer,  Ellis and Acton Bell (1846), published jointly by the sisters (who assumed  pseudonyms to avoid the special treatment that they believed reviewers  accorded to women), contained 21 of her poems. Many critics believe  that her verse alone reveals poetic genius. Her one novel, Wuthering  Heights (1847), is a highly imaginative story of passion and hatred set on  the Yorkshire moors. Though not a success when published, it later came  to be considered one of the finest novels in English. Soon after its pub�  lication, her health began to fail, and she died of tuberculosis at 30.

Though primarily residential, much of its more than 80 mi  (130 km) of waterfront is used for shipping, warehouses, and industry. It  is home to baseball�s Yankee Stadium. It has an extensive park system  and includes the Bronx Zoo and the New York Botanical Gardens.</p><p>Bronx Zoo formally New York Zoological Park Zoo in New</p><p>York City. It opened in 1899 on 265 acres (107 hectares) in the north�  western area of the Bronx. In 1941 it added the 4-acre (1.6-hectare) Afri�  can Plains, which features large groups of animals in natural surroundings.  The zoo also includes the World of Darkness (the world�s first major  exhibit of nocturnal animals, added in the 1960s), the World of Birds (a  huge, indoor free-flight exhibit), the Rare Animal Range (near-extinct  species in natural settings), a Children�s Zoo, Wild Asia (Asian mammals  and birds), and the Congo Gorilla Forest. Managed by the New York  Zoological Society and financed by the society and the city, it supports  much research and oversees the Wildlife Survival Center on St. Cathe�  rine�s Island, Georgia.</p><p>bronze Alloy traditionally composed of copper and tin. Bronze was first  made before 3000 bc (see Bronze Age) and is still widely used, though  iron often replaced bronze in tools and weapons after about 1000 bc  because of iron�s abundance compared to copper and tin. Bronze is harder  than copper, more readily melted, and easier to cast. It is also harder than  iron and far more resistant to corrosion. Bell metal (which produces pleas�  ing sounds when struck) is bronze with 20-25% tin content. Statuary  bronze, with less than 10% tin and an admixture of zinc and lead, is tech�  nically a brass. The addition of less than 1% phosphorus improves the  hardness and strength of bronze; that formulation is used for pump plung�  ers, valves, and bushings. Also useful in mechanical engineering are man�  ganese bronzes, with little or no tin but considerable amounts of zinc and  up to 4.5% manganese. Aluminum bronzes, containing up to 16% alumi�  num and small amounts of other metals such as iron or nickel, are espe�  cially strong and corrosion-resistant; they are cast or wrought into pipe  fittings, pumps, gears, ship propellers, and turbine blades. Most �copper�  coins are actually bronze, typically with about 4% tin and 1% zinc, or  copper plating over base metal.</p><p>Bronze Age Third phase in the development of material culture among  the ancient peoples of Europe, Asia, and the Middle East, following the  Paleolithic and Neolithic periods and preceding the Iron Age. The term also  denotes the first period in which metal was used. The date at which the  age began varied by region; in Greece and China it began before 3000  bc, in Britain not until c. 1900 bc. The beginning of the period is some�  times called the Chalcolithic (Copper-Stone) Age, referring to the initial  use of pure copper (along with its predecessor, stone). By 3000 bc the use  of copper was well known in the Middle East, had extended westward  into the Mediterranean area, and was beginning to infiltrate Europe. Only  in the 2nd millennium bc did true bronze come to be widely used. The age  was marked by increased specialization and the invention of the wheel  and the ox-drawn plow. From c. 1000 bc the ability to heat and forge iron  brought the Bronze Age to an end.</p><p>Bronzino \br6n-'dze-n6\, II orig. Agnolo di Cosimo (b. Nov. 17,  1503, Monticelli, duchy of  Milan�d.

He directed several innovative Shakespearean productions  that aroused controversy. Appointed codirector of the Royal Shakespeare  Co. in 1962, he directed critically acclaimed productions of King Lear  (1962) and A Midsummer Night�s Dream (1970). He won international  fame with his avant-garde direction of Peter Weiss�s play Marat/Sade  (1964). His films include Lord of the Flies (1962), King Lear (1969), and  the six-hour Mahabharata (1989).

The best known of the  many utopian communities organized in the U.S. in the mid-19th century,  Brook Farm was to combine the thinker and the worker, to guarantee the  greatest mental freedom, and to prepare a society of liberal, cultivated  persons whose lives would be more wholesome and simpler than they  could be amid the pressure of competitive institutions. It is remembered  for the distinguished literary figures and intellectual leaders associated  with it, including Charles A. Dana, Nathaniel Hawthorne, Margaret Fuller,  Horace Greeley, James Russell Lowell, John Greenleaf Whittier, and Ralph  Waldo Emerson (though not all of them were actual members). It was also  noted for the modem educational theory of its excellent school.

Brook�  lyn is connected to Manhattan by  bridges (including the Brooklyn  Bridge), a vehicular tunnel, and rapid  transit services. The first settlement  in the area by Dutch farmers in 1636  was soon followed by other villages, including Breuckelen (1645). The  Battle of Long Island was fought in Brooklyn in 1776. It became a bor�  ough of New York City in 1898. Brooklyn is both residential and indus�  trial and also handles considerable oceangoing traffic. Among its  educational institutions is Pratt Institute. Coney Island is located there.</p><p>Brooklyn Bridge Suspension bridge built (1869-83) over the East  River to link Brooklyn to Manhattan island. It was designed by the cable  manufacturer John A. Roebung and his son Washington. A brilliant feat of  19th-century engineering, the bridge was the first to use steel for cable  wire and the first in which explosives were used inside a pneumatic cais�  son during construction. In 1869 John was killed in one of at least 27  fatal construction accidents; his son saw the project to completion. The  bridge�s main span of 1,595 ft (486 m) was the longest in the world to  date.

After a brief marriage, in 1905 she moved to Paris where she established  herself in literary, artistic, and homosexual circles. Her reputation reached  its height in 1925 with several important exhibitions. Her gray-shaded  portraits, touched by occasional colour, distilled their subjects� person�  alities to a disturbing degree.

He worked for years at Stowe, Buckinghamshire,  one of the most talked-of gardens of the day, under William Kent (1685�  1748). By 1753 he was the leading �improver of grounds� in England. At  Blenheim Palace he created masterly lakes and almost totally erased the  earlier formal scheme. His landscapes consisted of expanses of grass,  irregularly shaped bodies of water, and trees placed singly and in clumps.  His style is often thought of as the antithesis of that of Andre Le Notre,  designer of the formal Versailles gardens. Brown�s nickname arose from  his habit of saying that a place had �capabilities.�</p><p>Brown, Charles Brockden (b. Jan. 17, 1771, Philadelphia, Pa.,  U.S.�d.

His gothic novels in American set�  tings were the first in a tradition later adapted by Edgar Allan Poe and  Nathaniel Hawthorne. Wieland (1798), his best-known work, shows the  ease with which mental balance is lost when common sense is confronted  with the uncanny. His writings reflect a thoughtful liberalism while  exploiting horror and terror. He has been called the �father of the Ameri�  can novel.�</p><p>Brown, Clifford (b.

He was a principal  figure in the hard-bop idiom (see bebop). After touring with Lionel Hamp�  ton�s big band in 1953, he worked with Art Blakey; in 1954 he and drum�  mer Max Roach formed a quintet that became one of the outstanding  groups in modem jazz.

In Italy (1845) he met Peter von Cornelius, a member of the Naz-  arenes, who influenced his palette and style. His use of brilliant colour,  meticulous handling, and taste for literary subjects had a strong effect on  the Pre-Raphaelites, most notably Dante Gabriel Rossetti. His most famous  paintings are The Last of England (1852-55), a poignant tribute to emi�  gration, and Work (1852-63), a Victorian social commentary. In 1861 he  became a founding member of William Morris�s company, for which he  designed stained glass and furniture.</p><p>Brown, George (b. Nov. 29,1818, Edinburgh, Scot.�d.

He later formed a trio,  appearing at small clubs throughout the South. He gradually evolved a  highly personal style, combining blues and gospel music elements with his  own emotionally charged and highly rhythmic delivery, accented by a  strong sense of showmanship. His first hit, �Please, Please, Please�  (1956), was followed by other million-selling singles, including �Papa�s  Got a Brand New Bag�; his style, marked by strong dance-oriented  rhythms and heavy syncopation, became known as funk. His checkered  personal life was highlighted in 1988 when he received a three-year jail  sentence on a variety of charges.</p><p>Brown, Jim orig. James Nathaniel Brown (b.

He propounded the �excitability� theory  published in Elementa medicinae (1780), which classified diseases as  over- or understimulating and held that internal and external �exciting  powers,� or stimuli, operate on living tissues. Brown viewed diseases as  states of decreased excitability, requiring stimulants, or increased excit�  ability, requiring sedatives. Hermann von Helmholtz discredited the theory.</p><p>Brown, John (b. May 9, 1800, Torrington, Conn., U.S.�d. Dec. 2,  1859, Charles Town, Va.) U.S. abolitionist. He grew up in Ohio, where  his mother died insane when he was eight. He moved around the country  working in various trades and raised a large family of 20 children. Though  he was white, he settled in 1849 with his family in a black community  founded at North Elba, N.Y. An ardent advocate of overt action to end  slavery, he traveled to Kansas in 1855 with five of his sons to retaliate  against proslavery actions in Lawrence. He and his group murdered five  proslavery settlers (see Bleeding Kansas). In 1858 he proposed to estab�  lish a mountain stronghold in Maryland for escaping slaves, to be financed  by abolitionists. He hoped that taking the federal arsenal at Harpers Ferry,  W.Va., would inspire slaves to join his �army of emancipation.� In 1859  his small force overpowered the arsenal�s guard; after two days it was in  turn overpowered by federal forces led by Col. Robert E. Lee. Brown was  tried for treason, convicted, and hanged. His raid made him a martyr to  northern abolitionists and increased the sectional animosities that led to  the American Civil War.</p><p>Brown, Joseph Rogers (b. Jan. 26,1810, Warren, R.I., U.S.�d.

He per�  fected and produced a highly accurate linear dividing engine in 1850, and  then developed a vernier caliper and also applied vernier methods to the  protractor. With Lucian Sharpe he founded the Brown and Sharpe Manu�  facturing Co. His micrometre caliper appeared in 1867. He invented a pre�  cision gear cutter to produce clock gears, a universal milling machine,  and (perhaps his finest innovation) a universal grinding machine, in which  articles were hardened first and then ground, thereby increasing accuracy  and eliminating waste.</p><p>Brown, Molly orig.

The daughter of Irish immigrants, she attended a  grammar school and later worked at a tobacco factory. She followed her  brother c. 1884 to Colorado, where she met and married James Brown, a  miner. After he found gold in 1894, they moved to Denver, where they  were welcomed into society. She became a founding member of the Den�  ver Woman�s Club, part of a national network of women�s clubs dedi�  cated to improving the conditions of women and children. After her  husband left her, she traveled to New York and Newport, where she  enjoyed social success. As a passenger on the disastrous maiden voyage  of the Titanic (1912), she helped command a lifeboat and was celebrated  by the U.S. press as �the Unsinkable Mrs. Brown.� Her life, in the semi�  legendary form she herself recounted it, was popularized in a stage musi�  cal and movie.</p><p>Brown, Robert (b.

He obtained the post of  naturalist aboard a ship bound to survey the coasts of Australia (1801),  and on the journey he gathered some 3,900 plant species. He published  some of the results of his trip in 1810 in his classic Prodromus Florae  Novae Hollandiae..., laying the foundations of Australian botany and  refining prevailing plant classification systems. In 1827 he transferred  Joseph Banks�s botanical collection to the British Museum and became  keeper of the museum�s newly formed botanical department. The follow�  ing year he published his observation of the phenomenon that came to be  called Brownian motion. In 1831 he noted the existence in plant cells of  what he called the nucleus.

North American brown bears are usually called griz�  zly bears. Eurasian brown bears are generally solitary animals, able to run  and swim well, and usually 48-84 in. (120-210 cm) long and 300-550  lbs (135-250 kg). They feed on mammals, fish, vegetable materials, and  honey. The exceptionally large Siberian brown bear is similar in size to  the grizzly.</p><p>brown dwarf Astronomical object intermediate in mass between a  planet and a star. Sometimes described as failed stars, brown dwarfs are  believed to form in the same way as stars, from fragments of an inter�  stellar cloud that contract into gravitationally bound objects. However,  they do not have enough mass to produce the internal heat that in stars  ignites hydrogen and establishes nuclear fusion. Though they generate  some heat and light, they also cool rapidly and shrink; they may differ  from high-mass planets only in how they form.</p><p>brown recluse spider Venomous species ( Loxosceles reclusa) of  brown spider, most common in the western and southern U.S. The brown  recluse is light-coloured, generally with a dark violin-shaped design on  its back, for which it is sometimes called the violin spider. About 0.25 in.  (7 mm) long, it has a leg span of about 1 in. (2.5 cm). It has extended its  range into parts of the northern U.S. and is often found under stones or  in dark corners inside buildings. The venom of the brown recluse destroys  the walls of blood vessels near the site of the bite, sometimes causing a  slow-healing skin ulcer. Bites are occasionally fatal.</p><p>brown trout Prized and wary European game fish ( Salmo trutta, fam�  ily Salmonidae) that is favoured for  food. The species includes several  varieties (e.g., the Loch Leven trout  of Britain). The brown trout is rec�  ognized by the light-ringed black  spots on its brown body. It has been  transplanted to many areas of the  world because it can thrive in  warmer waters than most other trout.</p><p>It grows to about 8 lbs (3.6 kg).</p><p>Oceangoing individuals, called sea  trout, are larger than freshwater  forms and provide good sport, as do those that enter large lakes.</p><p>Brown University Private university in Providence, Rhode Island,  U.S., a traditional member of the Ivy League. It was founded in 1764 as  Rhode Island College and renamed in 1804 for a benefactor, Nicholas  Brown. It became coeducational in 1971 when it merged with Pembroke,  a women�s college founded in 1891. Today it offers undergraduate and  graduate degrees in all major academic fields; its school of medicine  awards the M.D. Research facilities include centres for geological, astro�  nomical, and educational research.</p><p>Brown v. Board of Education (of Topeka) (1954) U.S. Supreme  Court case in which the court ruled unanimously that racial segregation  in public schools violated the 14th Amendment to the U.S. Constitution.  The amendment says that no state may deny equal protection of the laws  to any person within its jurisdiction. The court declared separate educa�  tional facilities to be inherently unequal, thus reversing its 1896 ruling in  Plessy v. Ferguson. The Brown ruling was limited to public schools, but it  was believed to imply that segregation is not permissible in other public  facilities. Guidelines for ending segregation were presented and school  boards were advised to proceed �with all deliberate speed.� See also Thur-  good Marshall.</p><p>Browne, Sir Thomas (b. Oct. 19, 1605, London, Eng.�d. Oct. 19,  1682, Norwich, Norfolk) British physician and author. While practicing  medicine, he began a parallel career as a writer. His best-known work,  Religio Medici (1642), is a journal of reflections on the mysteries of God,  nature, and man. A larger work commonly known as Browne�s Vulgar  Errors (1646) attempted to correct popular beliefs and superstitions. He  also wrote treatises on antiquarian subjects and the beautiful and subtle  A Letter to a Friend (1690).</p><p>Brownian motion Any of various physical phenomena in which some  quantity is constantly undergoing small, random fluctuations. It was  named for Robert Brown, who was investigating the fertilization process  of flowers in 1827 when he noticed a �rapid oscillatory motion� of micro�  scopic particles within pollen grains suspended in water. He later discov�  ered that similar motions could be seen in smoke or dust particles  suspended in air and other fluids. The idea that molecules of a fluid are  constantly in motion is a key part of the kinetic theory of gases, developed  by James Clerk Maxwell, Ludwig Boltzmann, and Rudolf Clausius (1822-  88) to explain heat phenomena.</p><p>Browning, Elizabeth Barrett orig. Elizabeth Barrett (b. March  6, 1806, near Durham, Durham,</p><p>Eng.�d. June 29, 1861, Florence)</p><p>British poet. Though she was an  invalid who was afraid to meet  strangers, her poetry became well  known in literary circles with the  publication of volumes of verse in  1838 and 1844. She met Robert  Browning in 1845 and, after a court�  ship kept secret from her despotic  father, they married and settled in  Florence. Her reputation rests chiefly  on the love poems written during  their courtship, Sonnets from the  Portuguese (1850). Her most ambi�  tious work, the blank-verse novel  Aurora Leigh (1857), was a huge  popular success.</p><p>Browning, Robert (b. May 7,</p><p>1812, London, Eng.�d. Dec. 12,</p><p>1889, Venice, Italy) British poet. His  early works include verse dramas,  notably Pippa Passes (1841), and  long poems, including Sordello (1840). In the years of his marriage  (1846-61) to Elizabeth Barrett Browning, spent in Italy, he produced little  other than Men and Women (1855), which contains dramatic lyrics such  as �Love Among the Ruins� and the great monologues �Fra Lippo Lippi�  and �Bishop Blougram�s Apology.� Dramatis Personae (1864), including  �Rabbi Ben Ezra� and �Caliban upon Setebos,� finally won him popular  recognition. The Ring and the Book (1868-69), a book-length poem, is  based on a 1698 murder trial in Rome. Browning influenced many mod�  ern poets through his development of the dramatic monologue (with its  emphasis on individual psychology) and through his success in writing  about the variety of modern life in language his contemporaries found  often difficult as well as original.</p><p>Browning, Tod orig. Charles Albert Browning (b. July 12,1880,  Louisville, Ky., U.S.�d. Oct. 6, 1962, Malibu, Calif.) U.S. film director.  He was a circus performer and vaudeville comic before joining the Bio�  graph film studio in 1915. He wrote several screenplays, then directed  melodramas and adventure films (1917-25). He directed the macabre film  The Unholy Three (1925), starring Lon Chaney, followed by Dracula  (1931) and Freaks (1932), which established his reputation for films of  horror and the grotesque.</p><p>Brownshirts See SA</p><p>Brownsville Affair Racial incident in 1906 in Brownsville, Texas,  involving white citizens of Brownsville and African American soldiers  stationed at nearby Fort Brown.

He  formed a quartet with saxophonist Paul Desmond in 1951. His use of  unconventional metres contributed to his immense appeal: the recording  of Desmond�s �Take Five� became the first jazz instrumental to sell more  than a million copies.

March 17, 1898, Washington, D.C.) U.S. senator from Mis�  sissippi during Reconstruction. Bom to a slave mother and a white father,  he was educated by his father. He moved to Mississippi, where he became  a significant figure in state politics and purchased a plantation. In the U.S.  Senate (1875-81), he advocated just treatment of African Americans and  Indians and opposed the policy of excluding Chinese immigrants. He later  served as register of the U.S. treasury (1881-85, 1895-98), District of  Columbia recorder of deeds (1889-95), and trustee of Howard Univer�  sity.</p><p>Bruce, Lenny orig. Leonard Alfred Schneider (b. Oct. 13, 1925,  Mineola, N.Y., U.S.�d. Aug. 3, 1966, Hollywood, Calif.) U.S. stand-up  comedian. He studied acting and began performing stand-up routines in  nightclubs in the 1950s, soon developing a style marked by black humour  and punctuated with obscenity. As he gained notoriety, he focused his  material on criticisms of the social and legal establishments, organized  religion, and other controversial subjects. His reputation acquired iconic  status as a daring performer and an activist for free speech after his death  from a drug overdose.</p><p>brucellosis X.bru-so-'lo-sosV or Malta fever or Mediterranean  fever or undulant fever Infectious disease of humans and domestic  animals. It is characterized by gradual onset of fever, chills, sweats, weak�  ness, and aches, and it usually ends within six months. It is named after  the British physician David Bruce (b. 1855�d. 1931), who first identi�  fied (1887) the causative bacteria. Three main species in the genus Bru�  cella commonly cause the disease in humans, who contract it from  infected animals (goats, sheep, pigs, cattle). Brucellosis is rarely trans�  mitted between humans but spreads rapidly in animals, causing severe  economic losses. Drug therapy is not practical for animal brucellosis, but  vaccination of young animals is useful. Infected animals must be removed  from herds. Antibiotics are effective against acute disease in humans, in  whom it can cause liver and heart problems if untreated.</p><p>Bruch VbriikX, Max (Karl August) (b. Jan. 6, 1838, Cologne,  Prussia�d.

He was known in his lifetime principally for his  many sacred and secular choral pieces, including Odysseus (1872) and  Das Lied von der Glocke (1879). Today he is remembered especially for  his first violin concerto (1868); he also wrote two further violin concer�  tos, the cello variations Kol Nidrei (1881), and operas and symphonies.</p><p>Brucke VbriE-kaV Die German "The Bridge" Organization of Ger�  man Expressionist artists. It was founded in 1905 by four architectural stu�  dents at the Dresden Technical School, including Ernst Ludwig Kirchner  and Karl Schmidt-Rottluff, who were soon joined by other German and  European artists. Its name reflects their hope that their work would be a  bridge to the art of the future. Strongly influenced by primitive art, Ger�  man Gothic woodcuts, and the prints of Edvard Munch, they produced fig�  ure paintings and portraits depicting human suffering and anxiety, as well  as still lifes and landscapes characterized by harshly distorted shapes and  violent colours. They contributed to the 20th-century revival of the wood-  cut. The group disbanded in 1913. See photograph opposite.</p><p>Bruckner Vbruk-nsrV (Josef) Anton (b. Sept. 4, 1824, Ansfelden,  Austria�d. Oct. 11, 1896, Vienna) Austrian composer. Son of a rural  schoolmaster who died in Anton�s youth, he was taken into a monastery  as a choirboy and there learned to play the organ. Greatly gifted, he  became organist at Linz Cathedral in 1855; throughout his composing  career, his orchestrations would be compared to organ sonorities. In 1865  he heai'd Tristan und Isolde in Munich and thereafter idolized Richard  Wagner, though his own works remained indebted to Ludwig van</p><p>Beethoven. In 1868 he was appointed professor at the Vienna Conserva�  tory and settled in Vienna for the rest of his life. He was 60 before he  achieved fame with his Symphony No. 7 in E Major (1884). He was  socially awkward and eccentric, and he remained a deeply devout Chris�  tian to his death. His reputation rests on his nine mature symphonies  (1866-96), his three masses, and his Te Deum (1884).</p><p>Bruegel Vbroi-golV Jan, the Elder (b. 1568, Brussels�d. Jan. 13,  1625, Antwerp) Flemish painter and draftsman, second son of Pieter Brue�  gel. Early in his career he went to Italy, where he painted under the  patronage of Cardinal Federigo Borromeo. After returning to Antwerp in  1596, he enjoyed a highly successful and prestigious career. In 1608 he  was appointed court painter to the archdukes of Habsburg, regents of the  southern Netherlands. He is known for his small-scale landscapes and  exquisite flower paintings, all painted in a miniaturistic style on copper  or panel. His skill at depicting delicate textures earned him the nickname  �Velvet.� He often collaborated with other artists, including his friend  Peter Paul Rubens. His sons, Jan the Younger and Ambrosius, were also  painters.</p><p>Bruegel Vbroi-golV Pieter, the Elder (b. c. 1525, probably Breda,  duchy of Brabant�d. Sept. 5/9, 1569, Brussels) Greatest Netherlandish  painter of the 16th century. Not much is known of his early life, but in  1551 he set off for Italy, where he produced his earliest signed painting,  Landscape with Christ and the Apostles at the Sea of Tiberias (c. 1553).  Returning to Flanders in 1555, he achieved some fame with a series of  satirical, moralizing prints in the style of Hieronymus Bosch, commissioned  by an Antwerp engraver. He is best known for his paintings of Nether�  landish proverbs, seasonal landscapes, and realistic views of peasant life  and folklore, but he also took a novel approach to religious subject mat�  ter, portraying biblical events in panoramic scenes, often viewed from  above. He had many important patrons; most of his paintings were com�  missioned by collectors. In addition to many drawings and engravings,  about 40 authenticated paintings from his enormous output have survived.  His sons, Peter Brueghel the Younger and Jan, the Elder Brueghel (both of  whom restored to the name the h their father had abandoned), and later  imitators carried his style into the 18th century.</p><p>Brugge Vbrui-ksA English Vbru-g9\ or Bruges VbruezhV City (pop.,  2000 est.: 116,200), northwestern Belgium.

It joined the Hanseatic League and  was a major marketplace in the 13th century. As the centre of the Flem�  ish cloth industry, it was the commercial hub of northern Europe. In the  15th century it was home to Jan van Eyck and other painters of the Flem�  ish school (see Flemish art).

The  leader of English fashion of his time,  he had by 1816 exhausted his inher�  ited fortune on gambling and  extravagance, and his sharp tongue  had alienated his patron. He fled to  Calais, France to avoid his creditors  and struggled for 14 years before  becoming British consul at Caen  (1830-32).

The country  is divided into two parts, each surrounded by the Malaysian state of</p><p>Sarawak; they both have coastlines on the  South China Sea and Brunei Bay. Area:</p><p>2,226 sq mi (5,765 sq km). Population  (2005 est.): 364,000. Capital: Bandar Seri  Begawan. Brunei has a mixture of South�  east Asian ethnic groups: about two-thirds are Malay, one-tenth Chinese,  and the remainder indigenous peoples and Indians. Languages: Malay  (official), English (widely understood). Religions: Islam (official; pre�  dominantly Sunni); also traditional beliefs, Buddhism, Christianity. Cur�  rency: Brunei dollar, ringgit. The narrow northern coastal plain gives way  to rugged hills in the south. Brunei�s western enclave consists of the val�  leys of the Belait, Tutong, and Brunei rivers and is mainly hilly. The east�  ern enclave contains the Pandaruan and Temburong river basins and the  country�s highest point, Pagon Peak (6,070 ft [1,850 m]). Much of Bru�  nei is covered by dense tropical rainforest; very little land is arable. Its  economy is dominated by production from major oil and natural gas fields.  It has one of the highest per capita incomes in Asia. Brunei is a monar�  chy; the head of state and government is the sultan. Brunei traded with  China in the 6th century ad. Through allegiance to the Javanese Majap-  AHlT kingdom (13th�15th century), it came under Hindu influence. In the  early 15th century, with the decline of the Majapahit kingdom, many con�  verted to Islam, and Brunei became an independent sultanate. When Fer�  dinand Magellan�s ships visited in 1521, the sultan of Brunei controlled  almost all of Borneo and its neighbouring islands. In the late 16th cen�  tury Brunei lost power because of the Portuguese and Dutch activities in  the region; they were soon joined by the British. By the 19th century the  sultanate of Brunei included Sarawak (including present-day Brunei) and  part of North Borneo (now part of Sabah). In 1841 a revolt took place  against the sultan, and a British soldier, James Brooke, helped put it down;  he was later proclaimed governor (see Brooke Raj). In 1847 the sultanate  entered into a treaty with Great Britain, and by 1906 it had yielded all  administration to a British resident. Brunei rejected membership in the  Federation of Malaysia in 1963, negotiated a new treaty with Britain in  1979, and achieved independence in 1984, with membership in the Com�  monwealth. Brunei has pursued ways to diversify the economy, notably  by encouraging tourism.</p><p>Brunei See Bandar Seri Begawan</p><p>Brunei \bru-'nel\, Isambard Kingdom (b.

His use of a compressed-air caisson to sink bridge pier foundations  helped gain acceptance of compressed-air techniques in underwater and  underground construction. Brunei made outstanding contributions to  marine engineering with three steamships�the Great Western, the Great  Britain, and the Great Eastern �each the largest in the world at date of  launching. The Great Western instituted the first regular transatlantic ser�  vice, and Great Eastern laid the first successful transatlantic cable.</p><p>Brunei, Sir Marc (Isambard) (b.

He perfected a method for making ships� blocks (pulleys) by  mechanical means rather than by hand; the system of 43 machines, run  by 10 men, produced blocks superior in quality and consistency to those  previously handmade by more than 100 men. This installation was an  early example of completely mechanized production (see mechanization).  In 1818 he patented the tunneling shield, a device that made safe tunnel�  ing through water-bearing strata possible. In 1825 operations began for  building the Brunei-designed tunnel under the River Thames, an unprec�  edented feat completed in 1842. He was the father of I.K.

Trained as a  sculptor and goldsmith, he turned his  attention to architecture after failing  to win a competition for the bronze  doors of the Baptistery of Florence,  having tied with Lorenzo Ghiberti. He  worked out the laws of linear per�  spective (later codified by Leon Bat�  tista Alberti). By the early 1420s  Brunelleschi was Florence�s most  prominent architect. His major work,  the octagonal dome of the cathedral  (1420-36), was constructed with the  aid of machines of his own inven�  tion. The Medici family commis�  sioned him to design the (old)  sacristy and basilica of San Lorenzo  (begun 1421), considered keystones  of the early Renaissance; he adhered  to the conventional format while  adding his own interpretation of  antique designs for capitals, friezes,  pilasters, and columns. His later monumental works foreshadowed the  strong profiles and massive grandeur of the work of Alberti and Donato  Bramante.</p><p>Brunhild Vbrun-.hildX (b. c. 534�d. 613, Reneve, Burgundy) Queen of  the Frankish kingdom of Austrasia.

One of the most force�  ful monarchs of the Merovingians, she urged Sigebert to reclaim her mur�  dered sister�s lands from Chilperic I. When her husband was assassinated  in 575, Brunhild was imprisoned at Rouen. She later took refuge at Metz,  where her son Childebert II had been proclaimed king, and she struggled  to establish her authority over her son and the reluctant Austrasian mag�  nates. After Childebert�s death she continued to influence affairs and  impose her will on her grandsons. After a long career she fell into the  hands of her enemies, including the founders of the Carolingian family;  she was tortured and then dragged to death by a horse.</p><p>Brunhild or Brunhilda or Brynhild Beautiful Amazon-like heroine  of ancient Germanic literature. She is known from Old Norse sources,  notably the Edda poems and the Vqlsunga saga, and from the German  Nibelungenlied. She also appears in the operas of Richard Wagner�s Ring  cycle. She vowed to wed only a man of the most outstanding qualities  who could surpass her in strength. She was successfully wooed by King  Gunther, who defeated her in a contest in which the deeds were actually  performed by Siegfried in cloak of invisibility. When she later discovered  that she had been deceived, she exacted vengeance, and Siegfried was  killed. Siegfried�s widow in turn sought revenge and brought about the  destruction of Gunther�s people, the Burgundians.

Leader of the  Catholic Centre Party from 1929, he became chancellor of Germany in  1930. In response to the Great Depression, he instituted harsh austerity  measures that paralyzed the German economy. He ignored the Reichstag  and governed by presidential decree, which hastened the drift toward  rightist dictatorship and Adolf Hitler�s rise to power.

His theology was influenced by Martin Buber�s view of the rela�  tionship between God and man. Like Karl Barth, he rejected 19th-century  liberal theology in favour of reaffirming the central tenets of the Refor�  mation, but his assertion that God was revealed in creation led to a dis�  pute with Barth.

The members of a mission he sent to  Poland, including Saints Benedict and John, were killed en route; Bruno  wrote biographies of both saints, as well as an acclaimed biography of  Adalbert. As archbishop, Bruno visited the rulers of Germany, Hungary,  and Ukraine, seeking aid. He temporarily converted the pagan Pechenegs.  He was killed on his way to his Prussian mission.</p><p>Bruno, Giordano orig. Filippo Bruno (b. 1548, Nola, near  Naples�d. Feb. 17, 1600, Rome) Italian philosopher, astronomer, math�  ematician, and occultist. He entered a Dominican convent in 1565 and  was ordained a priest in 1572. He abandoned the order in 1576 after being  accused of heresy. He moved to Geneva in 1578 and thereafter traveled  Europe as a lecturer and teacher. Rejecting the traditional geocentric  astronomy for a theory even more radical than that of Copernicus, he  hypothesized an infinite universe and multiple worlds. His cosmological  theories, which anticipated fundamental aspects of the modern concep�  tion of the universe, led to his excommunication by the Roman Catholic,  Calvinist, and Lutheran churches. In 1592 he was arrested and tried by  the Venetian Inquisition, which extradited him to the Roman Inquisition  in the following year. After a seven-year trial, he was burned at the stake.  His ethical ideas have appealed to modem humanists, and his ideal of  religious and philosophical tolerance has influenced liberal thinkers. His  most important works are On the Infinite Universe and Worlds (1584) and  The Expulsion of the Triumphant Beast (1584).</p><p>Brusa See Bursa</p><p>Brusilov \bru-'sye-lof\, Aleksey (Alekseyevich) (b.

They are distin�  guished from vascular plants and seed plants by the production of only one  SPORE-containing organ in their spore-producing stage. Most bryophytes  are 0.8-2 in. (2-5 cm) tall or, if reclining, generally less than 12 in. (30  cm) long. Found throughout the world, from polar regions to the tropics,  they are most abundant in humid environments, though none is marine.  Bryophytes are extremely tolerant of dry and freezing conditions. Peat  moss is economically important to humans in horticulture and as an energy  source. Some bryophytes are used ornamentally, as in moss gardens. In  nature, bryophytes initiate soil formation on barren terrain and maintain  soil moisture, and they recycle nutrients in forest ecosystems. They are  found on rocks, logs, and forest litter.</p><p>bryozoan V.bri-o-'zo-onV Aquatic invertebrate of the phylum Bryozoa  (�moss animals�), members (called zooids) of which form colonies.

Brought up in  Lemberg (now Lviv, Ukraine), he  studied in Vienna, Berlin, Leipzig,  and Zurich. Friedrich Nietzsche�s  heroic nihilism led Buber, a nonob�  servant Jew, to Zionism. He advo�  cated Jewish-Arab cooperation in  Palestine and saw Hasidism as a heal�  ing power for the malaise of modern  Judaism. Under Nazi pressure, he  emigrated to Palestine in 1938, and  he taught at Hebrew University until  1951. I and Thou (1923) expresses  Buber�s belief that the human (I)  encounters God (Thou) as a distinct  being, rather than merging in mysti�  cal union. The Bible was for Buber  derived from the encounter between  God and his people, but he rejected  many of the Talmud�s laws as emerging from a relationship in which God  was objectified rather than truly addressed.</p><p>Bubka Vbub-koN, Sergey (b.

As a teacher of Latin in Paris, Buchanan wrote bit�  ter attacks on the Franciscans that landed him in jail for heresy. He  escaped and became a teacher in Bordeaux, where Michel de Montaigne  was one of his pupils. There he translated two of Euripides� plays into Latin  and wrote original dramas. His paraphrase of the Psalms was long used  for Latin instruction. At first a supporter of Mary, Queen of Scots, he later  helped prepare the case that led to her execution.

He was admitted to  the bar in 1812 and soon established  a successful law practice. He was  elected to the Pennsylvania legisla�  ture in 1814 and later served in the  U.S. House of Representatives  (1821-31), as minister to Russia  (1832-34), and in the U.S. Senate  (1834-45). He was secretary of state  in the cabinet of Pres. James K. Polk  (1845-49). As minister to Britain  (1853-56), he helped draft the  Ostend Manifesto. In 1856 he was  elected president as a Democrat,  defeating John C. Fremont. Although  experienced in government and law,  he lacked the courage to deal effec�  tively with the slavery crisis, and he  equivocated on the question of Kan�  sas�s status as a slaveholding state. The ensuing split within his party  allowed Abraham Lincoln to win the election of 1860.

Inhabited from Neolithic times, Buda was  the site of a Roman camp in the 2nd century ad. By the 13th century both  Buda and Pest had German inhabitants. Buda was fortified by Matthias I  Corvinus in the 15th century and became the capital of Hungary. It was  taken and held by the Turks (1541-1686), then retaken by Charles V, duke  of Lorraine. In 1848-49 both towns experienced nationalistic revolt, and  Pest became the capital of Kossuth Lajos�s revolutionary government. It  became the centre of revolt for Hungarian independence in 1918. After  World War II, it came under communist control. It was the base of an  unsuccessful anticommunist uprising in 1956 (see Hungarian Revolution).

Siddhartha Gautama (fl. c. 6th-4th cen�  tury, b. Kapilavastu, Shakya republic, Kosala kingdom�d. Kusinara,  Mafia republic, Magadha kingdom) Indian spiritual leader and founder of  Buddhism. The term buddha (Sanskrit: �enlightened one�) is a title rather  than a name, and Buddhists believe that there are an infinite number of  past and future buddhas. The historical Buddha, referred to as the Bud�  dha Gautama or simply as the Buddha, was bom a prince of the Shak-  yas, on the India-Nepal border. He is said to have lived a sheltered fife  of luxury that was interrupted when he left the palace and encountered  an old man, a sick man, and a corpse. Renouncing his princely life, he  spent seven years seeking out teachers and trying various ascetic prac�  tices, including fasting, to gain enlightenment. Unsatisfied with the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Buddhism &#x25BA; Buffalo I 289</p><p>results, he meditated beneath the bodhi tree, where, after temptations by  Mara, he realized the Four Noble Truths and achieved enlightenment. At  Sarnath he preached his first sermon to his companions, outlining the  Eightfold Path, which offered a middle way between self-indulgence and  self-mortification and led to the liberation of nirvana. The five ascetics  who heard this sermon became his first disciples and were admitted as  bhiksus (monks) into the sangha, or Buddhist order. His mission fulfilled,  the Buddha died after eating poisonous mushrooms served him by acci�  dent and escaped the cycle of rebirth; his body was cremated, and stupas  were built over his relics.</p><p>Buddhism Major world religion and philosophy founded in northeast�  ern India in the 5th century bce. Based on the teachings of Siddhartha  Gautama, called the Buddha, Buddhism takes as its goal the escape from  suffering and from the cycle of rebirth: the attainment of nirvana. It  emphasizes meditation and the observance of certain moral precepts. The  Buddha�s teachings were transmitted orally by his disciples; during his  lifetime he established the Buddhist monastic order (sangha). He adopted  some ideas from the Hinduism of his time, notably the doctrine of karma,  but also rejected many of its doctrines and all of its gods. In India, the  emperor Ashoka promoted Buddhism during the 3rd century bc, but it  declined in succeeding centuries and was nearly extinct there by the 13th  century. It spread south and flourished in Sri Lanka and Southeast Asia,  and it moved through Central Asia and Tibet (see Tibetan Buddhism) to  China, Korea, and Japan (see Pure Land Buddhism; Zen). In the 19th cen�  tury, Buddhism spread to Europe and the United States, and it became  increasingly popular in the West in the second half of the 20th century.  Buddhism�s main teachings are summarized in the Four Noble Truths, of  which the fourth is the Eightfold Path. Buddhism�s two major branches,  Mahayana and Theravada, have developed distinctive practices and unique  collections of canonical texts. In the early 21st century, the various tra�  ditions of Buddhism together had more than 375 million followers.</p><p>Buddhist councils In most Buddhist traditions, two early councils on  doctrine and practice. The first, which most modern scholars do not accept  as historical, was reputedly held at Rajagrha (modern Rajgir), India, dur�  ing the first rainy season after the Buddha�s death, to compile his remem�  bered words, including the sutras and monastic rules. The second, which  is accepted as historical, met more than a century later at Vaisali, India,  to resolve disputes within the monastic community. Theravada Buddhism  recognizes subsequent councils: a third, called by Ashoka c. ad 247, at  which the doctrinal disputes were resolved in its favor, and others con�  tinuing up to the mid-20th century. Other Buddhist traditions recognize  other important councils at which their respective canons were established  or edited.</p><p>budding bacteria Group of bacteria that reproduce by budding. Each  bacterium divides following unequal cell growth; the mother cell is  retained, and a new daughter cell forms. In budding, the cell wall grows  from one point on the cell rather than throughout the cell; this type of  growth permits the development of more complex structures and pro�  cesses. Most budding bacteria are aquatic and can attach to surfaces by  their stalks; some are free-floating.</p><p>buddleia Vbod-le-oV or butterfly bush Any of more than 100 spe�  cies of plants constituting the genus Buddleia , native to tropical and sub�  tropical areas of the world.

First colonized by the Spanish in 1536, it was not permanently settled  until 1580. It became the seat of the Viceroyalty of the Rio de la Plata in  1776. In 1853 the city and the surrounding area that made up the prov�  ince of Buenos Aires refused to recognize a new constitution approved  by the country�s other provinces and began fighting with them intermit�  tently over control of the Argentine government. After being made a fed�  eral district and Argentina�s capital, it settled its wars with the other  provinces (1880) and by World War I (1914-18) had become a thriving  port.

An 1866 law authorized the army to form cavalry and infan�  try regiments of African American men under the command of white  officers; the result was the 9th and 10th cavalries and the 38th through  41st infantries. The primary mission of the cavalry regiments was to con�  trol Indians on the western frontier (the nickname �buffalo� was given by  the Indians). The soldiers took part in almost 200 engagements. Noted for  their courage and discipline, they had the army�s lowest desertion and  court-martial rates. One of the 10th Cavalry�s officers was John Pershing,  whose nickname �Black Jack� reflected his advocacy on behalf of Afri�  can American troops.</p><p>buffer Solution usually containing a weak acid and its conjugate weak  base, or a salt, of such a composition that the pH is held constant within  a certain range. An example is a solution containing acetic acid  (CH 3 COOH) and the acetate ion (CH 3 COCT). The pH depends on their  relative concentration and can be found with a simple formula involving  their ratio. Relatively small additions of acid or base will change the con�  centration of the two species, but their ratio, and hence the pH, will not  change much. Different buffers are useful in different pH ranges; they  include phosphoric acid, citric acid, and boric acid, each with their salts.  Biological fluids such as blood, tears, and semen have natural buffers to  maintain them at the pH required for their proper function. See also law  of MASS ACTION.</p><p>Buffett, Warren (b.

Returning to his native Omaha, he turned $105,000 of ini�  tial investment in his Buffett Partnership (1956-69) into $105 million by  the time of its dissolution. He then began investing in businesses, bought  under the umbrella of the textile manufacturer Berkshire Hathaway. He  is said to be the first person to have made $ 1 billion in the stock market.

He settled on his family�s estate, where he researched  the calculus of probability, the physical sciences, and forest management.  Appointed keeper of the royal botanical garden (Jardin du Roi) in 1739,  he was also assigned the cataloging of the royal natural history collec�  tions, an undertaking that grew into his comprehensive work Histoire  naturelle, generate et particuliere (1749-1804), an attempt to account for  all known flora and fauna, of which he published 36 of the proposed 50  volumes before his death. He was ennobled in 1773.</p><p>bug Coding error in a computer program that prevents it from function�  ing as designed. Most software companies have a quality-assurance  department which is charged with finding program bugs while the pro�  gram is in development (debugging); bugs are also often detected by  means of beta testing (testing of a product, often by potential consumers,  before it is placed on the market). The term originated in a computer con�  text in 1945 when a moth flew into and jammed an electrical relay of the  Harvard Mark II computer; it was extracted and taped into the log book  with the inscription �First actual case of bug being found� (the term hav�  ing previously been used for other kinds of mechanical defects).</p><p>bug Commonly, any insect; scientifically, any member of the insect order  Heteroptera. In scientific usage, when the word �bug� is part of the com�  mon name for a member of the order Heteroptera, it is a separate word  (e.g., �chinch bug�); when used as part of the common name for an  organism that is not a heteropteran, it is not separated (e.g., the ladybug,  in the order Coleoptera). In common usage, there are many exceptions to  this convention (e.g., bedbugs are heteropterans).</p><p>Bug \'bug\ River or Western Bug River River, eastern Europe.

Located along  the northern shore of Lake Victoria in present-day Uganda, the kingdom  was founded in the late 14th century by the Ganda people. Ruled by the  kabaka, or king, by the 19th century Buganda was the most powerful  kingdom in the area. In 1900 it became a British protectorate. The Ganda  subsequently played a major role in assisting British administration in  East Africa. When Uganda became independent in 1962, Buganda was  accorded special federal status within the new country. Ensuing tensions  with the central government led in 1967 to the kingdom�s abolition and  the area�s integration into Uganda.

The fleshy leaves function  as food reserves that enable a plant to lie dormant when water is unavail�  able (during winter or drought) and to resume active growth when favour�  able conditions again prevail. There are two main types of bulbs. One,  typified by the onion, has a thin papery covering protecting its fleshy  leaves. The other, the scaly bulb, as seen in true lilies, has naked storage  leaves, with no papery covering, making the bulb appear to consist of  angular scales. Bulbs enable many common ornamentals, such as the nar�  cissus, tulip, and hyacinth, to flower rapidly in early spring when growing  conditions are favourable. Other bulb-producing plants bloom in the sum�  mer (e.g., lilies) or fall (e.g., the autumn crocus).

Reli�  gions: Christianity (predominantly Eastern Orthodox; also other Chris�  tians); also Islam. Currency: lev. Three major regions define the  landscape. The northernmost is the Danubian Plain, a fertile area occu�  pying one-third of the country. Immediately south lie the Balkan Moun�  tains (Stara Planina). In the southwest and south lie the Rhodope  Mountains, with the country�s highest point, Musala Peak, rising 9,596  ft (2,925 m). Smaller than the three major regions, Bulgaria�s Black Sea  coast is a popular eastern European resort area. Major drainage systems  include the Black and Aegean seas. Bulgaria had a planned economy mod�  eled on the Soviet system (1946-89). Since 1991 the noncommunist gov�  ernment has been moving to privatize some sectors of the economy,  including agriculture.

The Byzantine Empire in 681 for�  mally recognized Bulgar control over the  area between the Balkans and the Danube,  though it would again dominate Bulgaria  from the early 11th century to the late 12th  century. Late in the 14th century Bulgaria fell to the Ottoman Turks and  again lost its independence. At the end of the Russo-Turkish War (1877�  78), Bulgaria rebelled. The ensuing Treaty of San Stefano was unaccept�  able to the great powers, and the Congress of Berlin (1878) resulted. In  1908 the Bulgarian ruler, Ferdinand, declared Bulgaria�s independence.  After its involvement in the Balkan Wars (1912-13), Bulgaria lost terri�  tory. It sided with the Central Powers in World War I and with Germany  in World War II. A communist coalition seized power in 1944, and in 1946  a people�s republic was declared. With other eastern European countries  in the late 1980s, Bulgaria experienced political unrest; its communist  leader resigned in 1989. A new constitution that proclaimed a republic  was implemented in 1991. Economic turmoil followed Bulgaria into the  21st century as it sought political stability and joined NATO in 2004.</p><p>Bulgarian Horrors Atrocities committed by the Ottoman empire in  subduing the Bulgarian rebellion of 1876. The name was used by William  E. Gladstone in his pamphlet publicizing the incident. About 15,000 per�  sons were reportedly massacred at Philippopolis (now Plovdiv), and vil�  lages and monasteries were destroyed. Despite widespread public  indignation, the European powers did little in response. The crisis ended  with the Congress of Berlin, which created a small, autonomous princi�  pality of Bulgaria.</p><p>Bulgarian language South Slavic language spoken by about nine  million people in Bulgaria and enclaves in Romania, Moldova, Ukraine,  and Turkey. Closely related is Macedonian, spoken by two to three mil�  lion people in Macedonia, adjacent parts of Albania and Greece, and  enclaves elsewhere. Both languages differ from other major Slavic lan�  guages in several features. Both are direct descendants of Old Church  Slavonic. Under Ottoman rule, literary production was solely in Church  Slavonic. The Bulgarian vernacular became a literary language only in  the mid-19th century; it was codified on the basis of northeastern Bul�  garian dialects in 1899. Though efforts to create a literary Macedonian  were underway before the Balkan Wars (1912-13), it was not formally  recognized as a distinct language until the declaration of a Macedonian  Republic within nascent communist Yugoslavia (1944).</p><p>Bulge, Battle of the (Dec. 16, 1944-Jan. 16, 1945) In World War II,  the last German offensive on the Western Front, an unsuccessful attempt  to divide the Allied forces and prevent an invasion of Germany. The  �bulge� refers to the wedge that the Germans drove into the Allied lines.  In December 1944, Allied forces were caught unprepared by a German</p><p>counterthrust in the wooded Ardennes region of southern Belgium. The  German drive, led by Gerd von Rundstedt�s panzer army, was initially suc�  cessful but was halted by Allied resistance and reinforcements led by  George Patton. The Germans withdrew in January 1945, but both sides  suffered heavy losses.</p><p>Buli style \'bu-le\ African wood sculpture made by the Luba people in  the village of Buli, Congo (Zaire). The most typical examples are statues  of ancestor figures and stools with seats supported on the heads and fin�  gertips of figures. Because the carvings are almost identical and differ  from other Luba carvings, they were once thought to be the work of a  single artist, known as the Master of Buli, but it was later determined that  they were actually produced in a workshop.</p><p>bulimia nervosa Nbii-Te-me-o-nor-'vo-soX Eating disorder, mostly in  women, in which excessive concern with weight and body shape leads to  binge eating followed by compensatory behaviour such as self-induced  vomiting or the excessive use of laxatives or diuretics. The disorder typi�  cally begins in adolescence or early adulthood and is associated with  depression, anxiety, and low self-esteem. Bulimia can have serious medi�  cal complications such as dental decay and dehydration. Treatment may  include psychotherapy. Unlike persons with anorexia nervosa, most  bulimics remain close to their proper weight.</p><p>bulk modulus Vma-jo-losV Numerical constant that describes the elas�  tic properties of a solid or fluid under pressure from all sides. It is the ratio  of the tensile strength or compressive force per unit surface area to the  change in volume per unit volume of the solid or fluid and thus is a mea�  sure of a substance�s ability to resist deformation. Its units are newtons  per square metre (N/m 2 ). Matter that is difficult to compress has a large  bulk modulus; for example, steel has a bulk modulus of 1.6 x 10 11 N/m 2 ,  three times that of glass (i.e., glass is three times more compressible than  steel).</p><p>Bull, John (b. 1562/63, Radnorshire, Wales?�d. March 12/13, 1628,  Antwerp, Spanish Netherlands) British composer. He became organist of  Hereford Cathedral in 1582, then organist at the Chapel Royal in 1591.  In 1613 he departed for the continent to escape punishment for adultery;  he held important organist positions in Brussels and Antwerp until his  death. He wrote many verse anthems but is remembered for his keyboard  works. In an era of remarkable English music for the virginal (a small  harpsichord), he produced works that, with their resourceful keyboard  figurations, reflect his own brilliant technique.</p><p>Bull \'bul. Ole (Bornemann) (b. Feb. 5, 1810, Bergen, Nor.�d. Aug.  17, 1880, Lyspen, near Bergen) Norwegian violinist. After training in his  native Bergen, he freelanced in Christiania (now Oslo) in 1828-31. His  Paris concerts, which featured Norwegian songs played on a folk violin,  won much attention, and he toured Europe and the U.S. for two decades.  A longtime nationalist, he was brought back home by the revolution of  1848. He helped found the Norwegian Theatre in Bergen, and in 1852-53  he established the socialist colony Oleona in Pennsylvania; debts from  the failed experiment kept him touring the rest of his life. Much of the  music he composed is lost.</p><p>bull market In securities and commodities trading, a rising market.

Robert La Follette in 1911 as the National Republican Progressive League,  it opposed the conservatism of the Republican Party controlled by Pres.  William H. Taft. The party derived its name from the characteristics of  strength and vigour that Roosevelt attributed to himself. In 1912  Roosevelt won 25% of the popular vote; thus split, the Republicans lost  the election to the Democratic candidate, Woodrow Wilson. The party  gradually dissolved, and the Republicans were reunited in 1916.

The first battle (also called First  Manassas) was fought on July 21, 1861, between 37,000 Union troops  under Gen. Irvin McDowell (1818-85) and 35,000 Confederate troops  under P.G.T. Beauregard and Joseph Johnston. In this first major encoun�  ter of the war, the Union assault was beaten back and the army retreated  to Washington, D.C. The second battle took place on Aug. 29-30, 1862,  between a Confederate force of more than 56,000 under Robert E. Lee and  a Union army of more than 70,000 under John Pope. To prevent the Union  army from being joined by the Army of the Potomac, Lee sent troops  under Stonewall Jackson to march around Pope�s right flank. Lee�s attack  forced the Union troops to withdraw as far as Washington, D.C. Casual�  ties numbered 15,000 for the North and 9,000 for the South. Both battles  strengthened the South�s resolve and caused the North to review its mili�  tary leadership and strategy.</p><p>bull terrier Breed of dog developed in 19th-century England from the  bulldog and the now-extinct white English terrier. The Spanish pointer was  later bred into the line to increase its size. The bull terrier was developed  as a courageous fighting dog but not an aggressive fight provoker, and it  is generally friendly. A muscular dog, it is considered, for its weight, the  strongest of all dogs. It has a short coat, tapering tail, erect ears, and deep-  set eyes. It stands 19-22 in. (48-56 cm) high and weighs 50-60 lbs (23-27  kg). There are two varieties, coloured and white.</p><p>bulldog or English bulldog Centuries-old breed of dog developed  in Britain to fight bulls. Powerful and courageous, often vicious, and  largely unaware of pain, the bulldog nearly disappeared when dogfight�  ing was outlawed in 1835. Fanciers of the breed saved it and bred out its  ferocity. It is now considered gentle and reliable. It has a large head, folded  ears, a short muzzle, a protruding lower jaw, and loose skin that forms  wrinkles on the head and face. Its short, fine coat is tan, white, reddish  brown, brindle, or piebald. It stands 13-15 in. (34-38 cm) high and weighs  40-50 lbs (18-23 kg).</p><p>Buller River River, South Island, New Zealand.

In the modern era, Roman  amphitheatres were rebuilt and  embellished for use as bullrings. The  largest are in Madrid, Barcelona, and  Mexico City. The corrida, which  usually involves six individual  fights, begins with a procession of  matadors and their entourages. At the  beginning of each fight an assistant  (banderillero) performs a prelimi�  nary maneuver to allow the matador  to assess the animal�s behaviour. The  matador then performs his capework,  drawing the bull as close to him as  possible without being gored. This is  followed by the entrance of the pica�  dors, horsemen who jab the bull with</p><p>lances to weaken its neck and shoulder muscles. The matador then ritu�  ally slays the bull using a sword. In the Portuguese version of the ritual,  the bull is fought from horseback and is not killed in the arena. Bullfight�  ing has been banned in many countries.</p><p>bullfinch Any of several species of stocky, stout-billed songbird (fam�  ily Fringillidae). Eurasia has six spe�  cies of the genus Pyrrhula, all boldly  marked. The common bullfinch ( P.  pyrrhula), 6 in. (15 cm) long, is  black and white; the male has a pink�  ish orange underside. It has a soft  warbling call and is a popular cage  bird. Usually found in evergreen  groves and hedgerows, it is notorious  for eating the buds of fruit trees. The  trumpeter bullfinch {Rhodopechys  githaginea), of arid localities from  the Canary Islands to India, is a pale  bird with a blaring buzzy note.</p><p>bullfrog Solitary aquatic frog  (Rana catesbeiana) named for its  loud call. The largest U.S. frog,  native to the eastern states, the bull�  frog has been introduced into the  western states and into other coun�  tries. The bullfrog is green or brown  with a white to yellowish belly and  dark-barred legs. Its body is about 8  in. (20 cm) long, and its hindlegs  may be 10 in. (25 cm) long. Large  adults weigh 1 lb (0.5 kg) or more.</p><p>Bullfrogs usually live in or near a  body of still water. They are used for  food and as laboratory animals. The  name is sometimes applied to other large frogs.</p><p>bullhead Any of several species of North American freshwater catfish  in the genus Ictalurus, valued as food and sport fishes. Bullheads are  related to the channel catfish (/. punctatus ) and other large North Ameri�  can species, but their tail is squared, rather than forked, and they are gen�  erally less than 12 in. (30 cm) long. The black bullhead (/. melas) is found  in the Mississippi Valley, the yellow and brown bullheads (/. natalis and  I. nebulosus) east of the Rocky Mtns., and the flat bullhead (I. platyceph-  alus ) in coastal streams between North Carolina and Florida. The name  is sometimes applied to sculpins.</p><p>bullionism Monetary policy of mercantilism, which called for national  regulation of transactions in foreign currency and precious metals (bul�  lion) in order to maintain a favourable balance in the home country. Bul�  lionism is most closely associated with 16th- and 17th-century Spain,  which was thought to owe its prosperity and military might to the gold  and silver of its New World colonies. This view gave rise to the theory  that a favourable balance of trade would increase the nation�s supply of  precious metals. Spain�s abundant treasure led it to buy goods and ser�  vices abroad at the neglect of domestic industry, causing it to experience  an economic decline.</p><p>Bullock, Wynn (b.

In 1948 Edward Weston persuaded him to focus on real�  ism and tonal beauty, and Bullock followed his advice so closely that his  images often resembled Weston�s. He is best known for realistic images  that are meant to be viewed as �equivalents,� or visual metaphors (e.g.,  the passing of time, the inevitability of death).</p><p>Bulow VbiE-loV Bernhard (Heinrich Martin Karl), prince von</p><p>(b.

His meetings with  the composers Franz Liszt (1849) and Richard Wagner (1850) led to his  decision to give up law for music, and with their help he launched a  renowned career as conductor and pianist, studying with Liszt from 1851  and marrying his daughter Cosima in 1857. He was appointed court con�  ductor to Louis II and later director of the Munich Conservatory. He con�  ducted the premieres of Wagner�s operas Tristan und Isolde (1859) and  Die Meistersinger (1868). Cosima abandoned von Biilow for Wagner,  whom she married in 1870; nonetheless, von Biilow continued to pro�  mote Wagner�s music. He was one of the first conductors to conduct from  memory; his interpretations were noted for their integrity and emotional  power.</p><p>bulrush Any of the annual or perennial grasslike plants constituting the  genus Scirpus, especially S. lacustris, in the sedge family, that bear soli�  tary or much-clustered spikelets. Bulrushes grow in wet locations, includ�  ing ponds, marshes, and lakes. Their stems are often used to weave strong  mats, baskets, and chair seats. Bulrushes may act as a filter, absorbing  poisonous metals and toxic microorganisms, thus helping to reduce water  pollution. In Britain, the term bulrush refers to either of two CATTAILS ( Typha  latifolia and T. angustifolia).</p><p>Bultmann \'bult- 1 man\ / Rudolf (Karl) (b. Aug. 20, 1884, Wiefelst-  ede, Ger.�d. July 30, 1976, Marburg, W.Ger.) German Protestant theo�  logian and New Testament scholar. The son of a Lutheran pastor, he studied  at the University of Tubingen and later taught many years at Marburg  (1921-51). He established his reputation with his analysis of the Gospels  in History of the Synoptic Tradition (1921). Influenced by his colleague  Martin Heidegger, he held that Christian faith should focus less on the his�  torical Jesus and more on the transcendent Christ, and he examined the  New Testament in mythical terms. During the Nazi era he supported the  anti-Nazi Confessing Church. His postwar books included Kerygma and  Myth (1953), History and Eschatology (1957), and Jesus Christ and  Mythology (1960).</p><p>Bulwer, Sir (William) Henry Lytton (Earle) later Baron  Dalling and Bulwer of Dalfing (b.

In the diplomatic  service from 1829, he negotiated the Ponsonby Treaty (1838), which was  advantageous to British trade with the Ottoman Empire. As ambassador  to the U.S. (1849-52), he negotiated the controversial Clayton-Bulwer  Treaty, which was intended to resolve (but in fact aggravated) Anglo-  American disputes in Latin America. In 1856 he played a major part in  the negotiations following the Crimean War. His brother was the novelist  Edward Bulwer-Lytton.</p><p>Bulwer-Lytton, Edward (George Earl) later 1st Baron Lyt�  ton (of Knebworth) (b. May 25, 1803, London, Eng.�d.

He entered Parliament as a Lib�  eral in 1831, retired in 1841, and returned in 1852 as a Tory. In the interim  he wrote his long historical novels, including The Last Days of Pompeii,  3 vol. (1834), and Harold, the Last of the Saxon Kings (1848). He was  created a peer in 1866. The opening to his 1830 novel Paul Clifford (�It  was a dark and stormy night...�) led to an annual Bulwer-Lytton Fiction  Prize, in which entrants vie to create the most overwritten first sentence  to a hypothetical novel.</p><p>bumblebee Any member of two genera constituting the insect tribe  Bombini (family Apidae, order Hymenoptera), found almost worldwide  but most common in temperate climates. Bumblebees are robust and hairy,  average about 0.6-1 in. (1.5-2.5 cm) in length, and are usually black with  broad yellow or orange bands. Bombus species are nest builders, often  nesting in the ground, commonly in deserted bird or mouse nests. They  live in organized groups, with a queen, drones, and workers (see caste).  Psithyrus species are social parasites (see parasitism); they lay their eggs  in Bombus nests, where the eggs and larvae are cared for by Bombus  workers.</p><p>Bunau-Varilla \bLE-no-va-re-'ya\, Philippe (-Jean) (b.

Within two months  after the Battles of Lexington and Concord, more than 15,000 colonial  troops assembled near Boston to prevent the British army from occupy�  ing several hills around the city, including Bunker and Breed�s hills. The  colonists fortified Breed�s Hill in Charlestown, across the Charles River  from Boston. They withstood a cannonade from British ships in Boston  Harbor and fought off assaults by 2,300 British troops but were eventu�  ally forced to retreat. Although the British won the battle, it was a Pyr�  rhic victory that lent considerable encouragement to the revolutionary  cause. British casualties (about 1,000) and the colonists� fierce resistance  convinced the British that subduing the rebels would be difficult.</p><p>bunraku Vbun-ra-ku\ Japanese traditional puppet theatre, in which  nearly life-size dolls act out a chanted dramatic narrative, called joruri ,  to the accompaniment of a small samisen.

July  29, 1983, Mexico City, Mex.) Spanish film director. As a student at the  University of Madrid he met Salvador Dau, with whom he later made the  Surrealist film Un chien andalou (1928). Bunuel then directed the anti�  clerical L�Age d�or (1930) and the documentary Land Without Bread  (1932). After working as a commercial producer in Spain and a technical  adviser in Hollywood, he moved to Mexico, where he directed Los olvida-  dos (1950) and Nazarin (1958). He returned to Spain to make Viridiana  (1961), which was suppressed in Spain as anticlerical but internationally</p><p>acclaimed. He attacked conventional  morality in such later films as Belle  de jour (1967), Tristana (1970), The  Discreet Charm of the Bourgeoisie  (1972), and That Obscure Object of  Desire (1977).</p><p>Bunyan, John (b.

Bunyan  encountered the seething religious  life of various left-wing sects while  serving in Oliver Cromwell�s army in  the English Civil Wars. He under�  went a period of spiritual crisis, con�  verted to Puritanism, and became a  preacher. After the Restoration, he  was jailed as a Nonconformist for 12  years, during which he wrote his  spiritual autobiography, Grace  Abounding (1666). He is best known  for The Pilgrim�s Progress (1678-  84), a religious allegory expressing  the Puritan religious outlook. A sym�  bolic vision of the character Chris�  tian�s pilgrimage through life, it was  at one time second only to the Bible  in popularity among ordinary read�  ers.

A  symbol of strength and vitality, he is  accompanied by a giant blue ox, Babe. He was credited with creating  Puget Sound, digging the Grand Canyon, and building the Black Hills,  and was known for his prodigious appetite, eating hotcakes off a griddle  so large it was greased by men using sides of bacon as skates. Tales of  his exploits probably originated in lumber camps, and were first published  by James MacGillivray in �The Round River Drive� (1910), which soon  led to a national myth.</p><p>Bunyoro See Nyoro</p><p>Buonarroti, Michelangelo See Michelangelo  buoyancy See Archimedes' principle</p><p>burakumin \bu- , ra-ku-min\ Japanese "hamlet people" Japanese  minority group that suffers discrimination based on its historical outcaste  status. In the late 16th century, when Toyotomi Hideyoshi divided the popu�  lace into four social classes, one group remained outside and beneath the  system: those whose occupation involved the taking of life (such as butch�  ers or executioners) or handling flesh or dead bodies (such as leather-  workers or gravediggers). Buddhist and Shinto beliefs in the polluting  nature of these occupations have long stigmatized those who held them.  Though their outcaste status was removed by law in 1871, prejudice  remains, and burakumin heritage often stands in the way of marriages and  employment opportunities. Burakumin are estimated to number 1-3 mil�  lion.</p><p>Burbage Vbor-bijV Richard (b. c. 1567, London, Eng.�d. March  9/13, 1619, London) British actor.

He  attended the Cleveland School of Art and, after service in World War I,  worked as a wallpaper designer in Buffalo, N.Y. In the 1920s and �30s  he was one of the leading painters of American life; his work was asso�  ciated with Edward Hopper�s in its portrayal of the loneliness and bleak�  ness of small-town life (e.g., November Evening , 1934). In the 1940s he  abandoned realism for a more personal interpretation of nature, empha�  sizing its mystery, movement, and colour from season to season (e.g..

After abandoning his study of theology, Burckhardt studied art history,  then a new field, at the University of Berlin (1839-43). As he matured  he became a cultural conservative, alienated from the contemporary world  and preoccupied with reclaiming the past. From 1843 he taught primarily  at the University of Basel; from 1886 until his retirement in 1893 he taught  art history exclusively. He is famous for The Civilization of the Renais�  sance in Italy (1860), which examines daily life in the Renaissance in  terms of such phenomena as the development of individuality and the  modern sense of humour; it became a model for cultural historians. He  died while working on a four-volume survey of Greek civilization.</p><p>burdock Any plant of the genus Arctium, in the composite family, bear�  ing globular flower heads with prickly bracts.

Its characteristics were first formulated systematically by Max  Weber, who saw in the bureaucratic organization a highly developed divi�  sion of labour, authority based on administrative rules rather than personal  allegiance or social custom, and a �rational� and impersonal institution  whose members function more as �offices� than as individuals. For Weber,  bureaucracy was a form of legalistic �domination� inevitable under capi�  talism. Later writers saw in bureaucracy a tendency to concentrate power  at the top and become dictatorial, as occurred in the Soviet Union. Robert  K. Merton emphasized its red tape and inefficiency due to blind confor�  mity to procedures. More recent theories have stressed the role of mana�  gerial cliques, occupational interest groups, or individual power-seekers  in creating politicized organizations characterized by internal conflict.</p><p>Burgas \bur-'gas\ City (pop., 2001: 802,932), eastern Bulgaria.

His bizarre ballad �Lenore� (1773) had a profound effect  on the subsequent development of literary Romanticism throughout  Europe, and he is remembered as a founder of German Romantic ballad  literature. He is also noted for his Petrarchan sonnets and translations from  English, especially Thomas Percy�s Reliques of Ancient English Poetry.</p><p>Burger, Warren E(arl) (b.

He graduated with honours  from St. Paul (now William Mitchell) College of Law in 1931, after which  he joined a prominent law firm and became active in the Republican Party.  He was appointed an assistant U.S. attorney general (1953) and named  to the U.S. Court of Appeals for the District of Columbia (1955), where  his conservative approach commended him to Pres. Richard Nixon, who  nominated him for chief justice of the Supreme Court of the United States  in 1969. Contrary to the expectations of some, he did not try to reverse  the liberal decisions on civil-rights issues and criminal law made during  the tenure of his predecessor, Earl Warren. Under his leadership, the court  upheld the 1966 Miranda v. Arizona decision, permitted busing as a means  of ending racial segregation in public schools, and endorsed the use of  racial quotas in the awarding of federal grants and contracts. Burger voted  with the majority in Roe v. Wade (1973). Keenly interested in judicial  administration, he became deeply involved in efforts to improve the judi�  ciary�s efficiency.

A Clockwork  Orange (1962; film, 1971), his most original work, is a satire on extreme  political systems. His other novels, which combine mordant wit, moral  seriousness, verbal dexterity, and the bizarre, include The Wanting Seed  (1962), Inside Mr. Enderby (1963), and Earthly Powers (1980).

At the University of Cambridge in the 1930s, he  became part of a group of young men, including Donald Maclean (1913�  83), who shared a disdain for capitalist democracy. They were recruited  by Soviet intelligence operatives and supplied information from their  positions, mainly in the British foreign office (Maclean from 1934, Bur�  gess from 1944). Maclean�s post with the British embassy in Washing�  ton, D.C., enabled him to pass secret information about NATO to the  Soviets; Burgess also served in Washington.

Assigned to Canada in 1776, he began a campaign to join British forces  from the north, south, and west to isolate the rebellious New England  colonies. In 1777 his army captured Fort Ticonderoga, N.Y., but was  stopped at the Hudson River by a larger army of colonists under Horatio  Gates and Benedict Arnold. After several months of fighting, he surren�  dered to Gates at Saratoga Springs, N.Y.; he returned to England to face  criticism for his defeat.</p><p>Burgundian school Group of 15th-century French composers, most  of whom were associated with courts of various dukes of Burgundy. They  are best known for their three-part chansons in rondeau form (see formes  fixes), usually with text only in the highest part�perhaps implying a solo  voice accompanied by instruments, written in full triadic harmony. The  most important Burgundian composers were Guillaume Dufay, Gilles Bin-  chois (c. 1400-60), and Antoine Busnois (c. 1430-92).</p><p>Burgundy French Bourgogne \biir-'g6n y \ Historical and govern�  mental region, France. The name was originally applied to a kingdom in  the Rhone valley and western Switzerland founded by the Burgundians, a  Germanic people who fled Germany in the 5th century. Conquered by the  Merovingians c. 534, it was incorporated into the Frankish empire. By the  843 Treaty of Verdun, which divided the empire of Charlemagne, it was  included in the Middle Kingdom of Lothar I. It was later divided into Cis-  jurane (Lower) Burgundy, or Provence (founded 879), and Transjurane  (Upper) Burgundy (founded 888); they united in 933 to form the king�  dom of Burgundy. After the 13th century, it was known as the kingdom  of Arles; the name Burgundy was applied to the duchy of Burgundy,  formed in the 9th century from lands in the northwestern part of the origi�  nal kingdom. On the death of Burgundy�s duke in 1361, the duchy  reverted to the French crown. Given to Philip II, by 1477 its lands extended  into the Low Countries. It was seized by Louis XI, annexed to the French  crown, and was a province until the French Revolution. Roughly coexten�  sive with the pre-Revolutionary province, the current administrative  region of Burgundy (1999: 1,610,067) covers 12,194 sq mi (31,582 sq  km). Its capital is Dijon. Wine making is an important part of the economy.</p><p>burial Ritual disposal of human remains. The practice is often intended  to facilitate the deceased�s entry into the afterworld. Grave burial dates  back at least 125,000 years. Types of graves range from trenches to large  burial mounds to great stone tombs such as pyramids. Caves have also long  been used for the dead�e.g., in ancient Hebrew burials, the sepulchral  caves (rock temples) of western India and Sri Lanka, and the Dogon cliff  burial sites. Water burial, such as occurred among the Vikings, has also  been common. Cremation and the scattering of ashes on water is widely</p><p>practiced, especially in Asia; in India the remains of the deceased are  thrown into the sacred Ganges River. Some peoples (American Indian  groups, Parsis, etc.) employ exposure to the elements to dispose of their  dead. Among many peoples, the first burial is followed by a second, after  an interval that often coincides with the duration of bodily decomposi�  tion. This reflects a concept of death as slow passage from the society of  the living to that of the dead. Jewish custom requires speedy burial; a  prayer known as the Kaddish is recited at the graveside, and a gravestone  is normally erected a year after burial. Christian burials are often preceded  by a wake, a �watch� held over the deceased�s body and sometimes  accompanied by festivity. Bodies of Muslims are laid on their right side  and facing Mecca.</p><p>Buridan \bui-re- , da n ,\ English \'byur-3d- 3 n\, Jean (b. 1300, Bethune?,  France�d. 1358) French philosopher, logician, and scientific theorist. He  studied under William of Ockham at the University of Paris and later taught  there. According to his modified version of determinism, though one must  choose what presents itself as the greater good, the will is free to delay  reason�s judgment by suggesting a more thorough inquiry into the worth  of one�s motives. The dilemma of a particular kind of moral choice,  between two evidently identical alternatives, is illustrated by the cel�  ebrated allegory of �Buridan�s ass.� Among his achievements in mechan�  ics was a revision of Aristotle�s theory of motion; he developed a theory  of impetus by which the mover imparts to the moved a power, propor�  tional to the former�s speed and mass, which keeps it moving. His stud�  ies of optical images prefigured modern developments in cinematics. In  logic he explicated the doctrines of Aristotle and Peter of Spain (c. 1210�  77). His works include Summula de dialecta (1487) and Consequents</p><p>(1493).</p><p>Burke, Edmund (b. January 12?, 1729, Dublin, Ire.�d. July 9, 1797,  Beaconsfield, Buckinghamshire, Eng.) British parliamentarian, orator, and  political philosopher. The son of a lawyer, he began legal studies but lost  interest, became estranged from his father, and spent some time wander�  ing about England and France. Essays he published in 1757-58 gained  the attention of Denis Diderot, Immanuel Kant, and Gotthold Lessing, and he  was hired to edit a yearly survey of world affairs (1758-88). He entered  politics (1765) as secretary to a Whig leader and soon became involved  in the controversy over whether Parliament or the monarch controlled the  executive. He argued (1770) that George Ill�s efforts to reassert a more  active role for the crown violated the constitution�s spirit. Elected to Par�  liament (1774-80), he contended that its members should exercise judg�  ment rather than merely follow their constituents� desires. Although a  strong constitutionalist, he was not a supporter of pure democracy;  although a conservative, he eloquently championed the cause of the  American colonists, whom he regarded as badly governed, and he sup�  ported the abolition of the international slave trade. He tried unsuccess�  fully to legislate relief for Ireland and to reform the governance of India.  He disapproved of the French Revolution for its leaders� precipitous  actions and its antiaristocratic bloodshed. He is often regarded as the  founder of modern conservatism.</p><p>Burkina Faso \bur-'ke-n9-'fa-so\ formerly Upper Volta Country,  West Africa. A landlocked country, it lies south of the Sahara Desert. Area:  103,456 sq mi (267,950 sq km). Population (2005 est.): 13,492,000. Capi�  tal: Ouagadougou. Ethnic groups are the Mossi, Hausa, Fulani, Mande,  Bobo, and Senufo. Languages: French (official), Mossi, Dyula, Fula. Reli�  gions: Islam, traditional beliefs, Christianity. Currency: CFA franc.  Burkina Faso consists of an extensive plateau characterized by a savanna,  grassy in the north and sparsely forested in the south. The plateau is  notched by the valleys of the Mouhoun (Black Volta), Nazinon (Red  Volta), and Nakanbe rivers, which flow south into Ghana. The economy  is largely agricultural. Burkina Faso is a republic with one legislative  body; its chief of state is the president and its head of government the  prime minister. Probably in the 14th century, the Mossi and Gurma  peoples established themselves in eastern and central areas. The Mossi  kingdoms of Yatenga and Ouagadougou existed into the early 20th cen�  tury. A French protectorate was established over the region (1895-97),  and its southern boundary was demarcated through an Anglo-French  agreement. It was part of the Upper Senegal-Niger (see Mali) colony, then  became a separate colony in 1919. It was constituted an overseas terri�  tory within the French Union in 1947, became an autonomous republic  within the French Community in 1958, and achieved total independence in  1960. Since then it has been ruled primarily by the military and has expe�  rienced several coups; the country received its present name in 1984.

March 23, 1993, England) British surgeon and medical researcher. He  discovered Burkitt lymphoma, a lethal cancer of the lymphatic system with  a high incidence among children. He showed that it was common in  equatorial African regions where malaria and yellow fever are endemic  and linked it to Epstein-Barr virus in children with immune systems  depressed by chronic malaria. He later helped develop an effective che�  motherapy treatment. Burkitt was also known for his theory that a high-  fibre diet protects against colon cancer, publicized in his book Don�t  Forget Fibre in Your Diet (1979).</p><p>burlesque In literature, comic imitation of a serious literary or artistic  form that relies on an extravagant incongruity between a subject and its  treatment. It is closely related to parody, though burlesque is generally  broader and coarser. Early examples include the comedies of Aristophanes.  English burlesque is chiefly drama. John Gay�s The Beggar�s Opera  (1728), Henry Fielding�s Tom Thumb (1730), and Richard Brinsley Sheridan�s  The Critic (1779) are parodies of popular dramatic forms of the period.  Victorian burlesque, usually light entertainment with music, was eclipsed  by other popular forms by the late 19th century, and burlesque eventu�  ally came to incorporate and be identified with striptease acts (see bur�  lesque show).</p><p>burlesque show Stage entertainment composed of slapstick sketches,  bawdy humour, chorus numbers, and solo dances. Introduced in the U.S.  in 1868 by a company of English chorus girls, it developed as a version  of the minstrel show, divided into three parts: (1) a series of coarse humor�  ous songs, slapstick sketches, and comic monologues; (2) the olio, or  mixture of variety acts (e.g., acrobats, magicians, singers); and (3) cho�  rus numbers and occasionally a takeoff, or burlesque, on politics or a cur�  rent play. The show ended with an exotic dancer or a boxing match. In  the early 20th century, many performers, including Fanny Brice, Al Jol-  son, and W.C. Fields, began their careers in burlesque. The addition of the  striptease in the 1920s made a star of Gypsy Rose Lee, but censorship and  competition from motion pictures soon led to burlesque�s decline.</p><p>Burlingame, Anson (b.

As U.S. minister to China (1861-67), he implemented a policy of  cooperation between China and the Western powers. He so impressed the</p><p>Chinese government that in 1867 he  was appointed imperial envoy to  conduct China�s international rela�  tions.

Completed in 1939, it functioned as a supply route  to the interior of China, carrying war goods. It was seized by the Japa�  nese in 1942 and reopened when it was connected to the Stilwell Road  from India. Its importance diminished after World War II, but it has  remained a link in a 2,100-mi (3,400-km) road system from Yangon,  Myanmar, to Chongqing.</p><p>Burmese cat Breed of domestic cat, presumably of Asian origin. Com�  pactly built, it has a small, rounded head and wide-set, round, yellow eyes.

The tapered tail may be kinked near  the tip.</p><p>burn Damage caused to the body by contact with flames, hot substances,  some chemicals, radiation (including sunlight), or electricity. Bums are  classified by depth of skin damage and by percentage of skin damaged.  First-degree burns injure only the epidermis (top layer), with redness,  pain, and minimal edema. In a second-degree burn, damage extends into  the dermis (inner layer), with redness and blisters. Third-degree burns  destroy the entire thickness of the skin. There is no pain, because the  skin�s pain receptors are destroyed. Burns deeper than the skin can release  toxic materials into the bloodstream and may require amputation. Sec�  ondary shock follows severe bums, caused by loss of fluid both in the  destroyed tissue and in leaks from the damaged area. Treatment depends  on severity; first-degree bums need only first aid; third-degree burns  require long-term hospitalization. Depending on the type, extent, and site  of the burn, it may be left exposed, covered with a bandage, or excised  to remove dead tissue in preparation for skin grafts. Complications of  bums include respiratory problems, infection, ulcers in the stomach or  duodenum, and, especially in brown skin, thick scarring.

He later discovered a method for identifying  bacteria by the viruses (bacteriophages) that attack them, and he shared a  1960 Nobel Prize with Peter Medawar for the discovery of acquired immu�  nological tolerance to tissue transplants. He was knighted in 1951.</p><p>Burnett, Carol (b. April 26, 1933, San Antonio, Texas, U.S.) U.S.  comedian and actress. She made her Broadway debut in Once upon a  Mattress (1959), then appeared regularly on television in The Garry  Moore Show (1959-62). Her gift for parody and her knock-kneed comic  grace gained her a wide following. The weekly Carol Burnett Show  (1966-77) became one of television�s most popular programs and won  her five Emmy Awards. She acted in several films, including Pete �n � Tillie  (1972) and Annie (1982), and returned to Broadway in Moon over Buf�  falo (1995).</p><p>Burnett, Frances (Eliza) Hodgson (b.

She is best remembered for the popular children�s novel Little  Lord Fauntleroy (1886), about an American boy who inherits an English  earldom. The Secret Garden (1911), considered her best work, is a clas�  sic of children�s literature. Other works include the novel Through One  Administration (1883), about corruption in Washington, D.C., and the play  A Lady of Quality (1896).</p><p>Burney, Charles (b.

In 1770  he set off on European travels, undertaken to research his seminal Gen�  eral History of Music, 4 vol. (1776-89). His accounts of the many famous  musicians and others he met, including Christoph Willibald Gluck and Carl  Philipp Emanuel Bach, provide an entertaining and invaluable account of  18th-century European musical life and of intellectual life in general.

The self-educated  daughter of Charles Burney, she  wrote lively accounts of his social  musical evenings. Her habit of  recording observations of society led  to Evelina (1778), an epistolary novel  about an unsure young girl�s social  development; a landmark in the evo�  lution of the novel of manners, it  pointed the way to Jane Austen�s  novels.

Bums and  Allen formed a comedy team in 1925 and were married in 1926. They  performed on radio in The George Burns and Grade Allen Show (1932�  50), with Bums playing the straight man to Allen�s malaprop-prone chat�  terbox, before their show moved to television (1950-58). They made 13  films together, including The Big Broadcast films of 1932, 1936, and  1937. Burns returned to the screen in films such as The Sunshine Boys  (1975, Academy Award) and Oh, God!

His father�s farm  failed, and a farm he started himself  quickly went bankrupt. Handsome  and high-spirited, he engaged in a  series of love affairs, some of which  produced children, and celebrated  his lovers in his poems. His Poems,</p><p>Chiefly in the Scottish Dialect (1786)  brought acclaim but no financial  security, and he eventually took a job  as an exciseman. He later began col�  lecting and editing hundreds of tra�  ditional airs for James Johnson�s  Scots Musical Museum (1787�1803)  and George Thomson�s Select Col�  lection of Original Scotish Airs  (1793-1818); he substantially wrote  many of these songs, though he did  not claim them or receive payment for them. Among his best-known songs  are �Auld Lang Syne,� �Green Grow the Rashes, O,� �John Anderson My  Jo,� �A Red, Red Rose,� and �Ye Banks and Braes o� Bonnie Doon.� He  freely proclaimed his radical opinions, his sympathies with the common  people, and his rebellion against orthodox religion and morality.</p><p>Burnside, Ambrose (Everett) (b.

A graduate of West Point, he was promoted to major general in 1862  and replaced George B. McClellan as commander of the Army of the  Potomac; he was himself replaced after the Union loss at the Battle of  Fredericksburg. He resigned in 1864 after the �Burnside mine� fiasco in  the Petersburg Campaign, when a mine explosion intended to damage  Confederate troops resulted in heavy Union losses.

He had a successful law practice in New York from  1782 and served as state attorney general (1789-91) and in the U.S. Sen�  ate (1791-97). In 1800 he won the vice presidential nomination on the  Jeffersonian Republican ticket. In the election, he and Thomas Jefferson  received the same number of electoral college votes; under procedures  then prevailing, the electors had cast their votes for both Jefferson and  Burr without indicating which should be president and which vice presi�  dent.

Following some remarks by Hamilton about Burr�s  character, Burr challenged him to a duel, in which Hamilton was mortally  wounded. Burr fled to Philadelphia, where with Gen. James Wilkinson he  planned an invasion of Mexico. He was tried for treason in 1807 before  John Marshall, whose narrow interpretation of the constitutional charge  led to acquittal. Under a cloud, Burr left for Europe, where he tried in  vain to interest English and French authorities in his scheme to conquer  Florida. In 1812 he returned to New York to resume his law practice.</p><p>burro See donkey</p><p>Burroughs, Edgar Rice (b. Sept. 1, 1875, Chicago, Ill., U.S.�d.  March 19, 1950, Encino, Calif.)

In his early years he worked as a teacher, farmer, and U.S. Trea�  sury Department clerk. In 1873 he moved to a farm in the Hudson River  valley. Traveling extensively, he hiked and camped with John Muir and  Theodore Roosevelt, among other friends, and accompanied an expedition  to Alaska. His many books helped establish the genre of the nature essay;  they include Wake-Robin (1871), Birds and Poets (1877), Locusts and  Wild Honey (1879), Ways of Nature (1905), and Field and Study (1919).</p><p>Burroughs, William S(eward) (b.

In 1885 he constructed his first calculating  machine; though it proved commercially impractical, he patented a prac�  tical model in 1892. This machine was a commercial success, but he died  before he could earn much money from it. A year before his death he  received the Franklin Institute�s John Scott Medal. In 1905 the Burroughs  Adding Machine Co. was organized as successor to the company he had  started. William S. Burroughs was his grandson.</p><p>Burroughs, William S(eward) (b.

Burroughs, he attended Harvard University and  later became a member of the central group of the Beat movement. His  experimental novels evoke, in deliberately erratic prose, a nightmarish,  sometimes wildly humorous world. His early Junkie (1953) frankly  describes his experiences as a heroin addict. The Naked Lunch (1959; film,  1991), his best-known work, is preoccupied with homosexuality and  police persecution and vividly satirizes the grotesque world of the addict.  (Burroughs accidentally killed his second wife while executing a drunken  prank.) In his later novels, including The Soft Machine (1961), Nova  Express (1964), The Wild Boys (1971), Cities of the Red Night (1981),  and The Western Lands (1987), he further experimented with dystopian  visions and radical technical devices.</p><p>Bursa formerly Brusa ancient Prusa City (pop., 1997: 1,066,559),  northwestern Turkey. It was founded in the 3rd century bc, at the foot of  the Mysian Mount Olympus near the southeastern shore of the Sea of  Marmara, as the seat of the kings of Bithynia. It flourished under the  Romans (see Roman Republic and Empire) and later under the Byzantine  Empire. After Crusaders conquered Constantinople (modern Istanbul) in  1204, it was a seat of Byzantine resistance. The Ottoman Empire took it in  the early 14th century and made it their first great capital. Conquered by  Timur in the early 15th century, it was later recovered by the Ottomans.

He  taught at the University of London (1924-50), becoming known for his  pioneering work in educational psychology, especially mental testing and  statistical analysis. His studies of human intelligence convinced him that  intelligence was primarily inherited. Subsequent examination indicated  that he had fabricated some of the data, though some of his earlier work  remained unaffected by this revelation. His books, which were very popu�  lar in England and went through many editions, include The Factors of  the Mind (1940), The Backward Child (1961), The Young Delinquent  (1965), and The Gifted Child (1975).</p><p>Burton, Richard orig.

He first won success on the stage in The Lady�s Not for Burning  in London (1949) and on Broadway (1950). His first Hollywood film role  was in My Cousin Rachel (1952). During the filming of Cleopatra (1963)  he had a highly publicized love affair with Elizabeth Taylor, whom he later  twice married. Known for his resonant voice and his Welsh mournfulness,  he starred again on Broadway in Camelot (1960) and an acclaimed Hamlet  (1964).

He spent most  of his life as a vicar at Oxford. His great Anatomy of Melancholy (1621)  describes the kinds, causes, symptoms, and cures of melancholy in a  lively, elegant, and sometimes humorous style; a mine of classical erudi�  tion and curious information, it is an index to the philosophical and psy�  chological ideas of its time. His Latin comedy Philosophaster (1606) is  a vivacious exposure of charlatanism.</p><p>Burton, Sir Richard (Francis) (b. March 19, 1821, Torquay, Devon�  shire, Eng.�d. Oct. 20, 1890, Trieste, Austria-Hungary) English scholar-  explorer and Orientalist. Expelled from Oxford in 1842, Burton went to  India as a subaltern officer. There he disguised himself as a Muslim and  wrote detailed reports of merchant bazaars and urban brothels. He then  traveled to Arabia, again disguised as a Muslim, and became the first non-  Muslim European to penetrate the forbidden holy cities; he recounted his  adventures in Pilgrimage to El-Medinah and Mecca (1855-56), a classic  account of Muslim life. In 1857-58 he led an expedition with John Han�  ning Speke in search of the source of the Nile River; stricken with malaria,  he turned back after becoming the first European to reach Lake Tanga�  nyika. His travels resulted in a total of 43 accounts of such subjects as  Mormons, West African peoples, the Brazilian highlands, Iceland, and  Etruscan Bologna. He learned 25 languages and numerous dialects;  among his 30 volumes of translations were ancient Eastern manuals on  the art of love, and he larded his famous Arabian Nights translation with  ethnological footnotes and daring essays that won him many enemies in  Victorian society. After his death his wife, Isabel, who was a devout  Catholic, burned his 40 years of diaries and journals.</p><p>Buru Dutch Boeroe \'bii-ru\ Island, Indonesia.

In the west the</p><p>Rusizi River connects Lake Kivu in the north with Lake Tanganyika to the  south. Burundi has a developing economy based primarily on agriculture.  It is governed by a military regime. It has one legislative house, and its  head of state and government is the president assisted by a vice president.  Original settlement by the Twa was followed by Hutu settlement, which  occurred gradually and was completed by the 11th century. The Tutsi  arrived 300-400 years later; though a minority, they established the king�  dom of Burundi in the 16th century. In the 19th century the area came  within the German sphere of influence, but the Tutsi remained in power.  Following World War I, the Belgians took control of the area; their admin�  istration was replaced by a UN trusteeship after World War II. Colonial  conditions had intensified Hutu-Tutsi ethnic animosities, and, as indepen�  dence neared, hostilities flared. Independence was granted in 1962 in the  form of a kingdom ruled by the Tutsi. In 1965 the Hutu rebelled but were  brutally repressed. The two groups clashed violently throughout the rest  of the 20th century, although the number of deaths did not approach the  nearly one million people killed in Rwanda. The unstable government that  existed in these surroundings was overthrown by the military in 1996. In  2001 a transitional government took power, but political instability con�  tinued in the region.</p><p>bus Device on a computer�s motherboard that provides a data path  between the CPU and attached devices (keyboard, mouse, disk drives,  video cards, etc.). Like a vehicular bus that stops at designated stations  to pick up or drop off riders, a computer bus receives a data signal from  the CPU and drops it off at the appropriate device (for example, the con�  tents of a file in RAM are sent, via the bus, to a disk drive to be stored  permanently). Conversely, data signals from devices are sent back to the  CPU. On a network, a bus provides the data path between the various  computers and devices.

The first gasoline-powered bus was  built in Germany in 1895 and carried eight passengers. The first integral-  frame bus was constructed in the early 1920s in the U.S. In the 1930s  diesel engines were introduced, providing greater power and fuel efficiency  to larger buses. With the development of highway systems, transconti�  nental bus lines became common in North America. Double-decked buses  are used in some European cities; articulated buses pull trailers with flex�  ible joints. Trolley buses, whose electric motors draw power from over�  head wires, are now used mostly in European cities.</p><p>Bush, George (Herbert Walker) (b. June 12, 1924, Milton, Mass.,  U.S.) 41st president of the U.S. (1989-93). Bush was the son of Prescott  Bush, an investment banker and U.S. senator from Connecticut. He served  in World War II as a toipedo bomber pilot on aircraft carriers in the Pacific,  flying some 58 combat missions; he was shot down by the Japanese in  1944. After graduating from Yale University in 1948, he started an oil  business in Texas. He was elected to a Republican seat in the U.S. House  of Representatives (1966-70) and later served as ambassador to the UN  (1971-72), chief of liaison to China (1974-76), and head of the CIA  (1976-77). In 1980 he lost the Republican Party nomination for president  to Ronald Reagan. Bush served as vice president under Reagan (1981�  89), whom he succeeded as president, defeating Michael Dukakis. He  made no dramatic departures from Reagan�s policies. In 1989 he ordered  a brief military invasion of Panama, which toppled that country�s leader,  Gen. Manuel Noriega. He helped impose a UN-approved embargo against  Iraq in 1990 to force its withdrawal from Kuwait. When Iraq refused, he  authorized a U.S.-led air offensive that began the Persian Gulf War.  Despite general approval of his foreign policy, an economic recession led  to his defeat by Bill Clinton in 1992. His son George W.

After spending a decade  in the oil business with mixed suc�  cess, he served as managing general  partner of the Texas Rangers profes�  sional baseball franchise. In 1994 he  was elected governor of Texas and  won reelection by a landslide in  1998. In 2000 Bush captured the  Republican Party presidential nomi�  nation. Despite losing the national  popular vote to Al Gore by more  than 500,000 votes, he gained the  presidency when the U.S. Supreme  Court reversed a recount order by the  Florida Supreme Court, enabling  him to secure a narrow majority in  the electoral college (271-266). In  June 2001 Bush signed into law a  $1.35 trillion tax-cut bill. In foreign affairs, his administration refused to  abide by the Kyoto Protocol on reducing the emission of gases respon�  sible for the greenhouse effect, withdrew from the Treaty on the Limita�  tion of Anti-Ballistic Missile Systems, and attempted to remove U.S.  citizens from the jurisdiction of the new International Criminal Court. Fol�  lowing the terrorist attacks on the World Trade Center in New York City  and the Pentagon building near Washington, D.C., in September 2001 (see  September 11 attacks), the Bush administration�s main priorities shifted to  domestic security and counterterrorism. Bush identified Osama bin Laden  and his al-Qaeda network as responsible for the attacks. In October he  launched a military campaign against Afghanistan�s Taliban government,  which harboured bin Laden; the invasion of the country routed al-Qaeda  and forced the Taliban from power. In late 2002 Bush and British Prime  Minister Tony Bair accused the Iraqi government of Saddam Hussein of  continuing to possess and develop biological, chemical, and nuclear weap�  ons in violation of UN mandates. After failing to persuade France, Rus�  sia, and other UN Security Council members that those weapons would  not be uncovered by UN weapons inspections, which had resumed in  November, Bush and Blair led an attack on Iraq that toppled Saddam�s  regime in 2003. Though no such weapons were found, fighting continued  and escalated, as the United States helped Iraq pave the way for demo�  cratic elections.

Franklin Roosevelt, he laid the groundwork for the establishment  of the National Science Foundation (1950). An information retrieval and  annotation system he described became the theoretical prototype of hyper�  text, the basis of the World Wide Web.</p><p>bushido \'bu-shi-do\ Japanese "way of the warrior" Code of  conduct of the samurai class of Japan, first formulated in the 17th century.  Its precise content varied over time, taking on overtones of Zen Buddhism  and Confucianism. Along with self-discipline, honour, and austerity, one  constant feature was the samurai�s obligation to his lord, which super�  seded even familial ties. This obligation of loyalty and sacrifice was trans�  ferred to the emperor with the Meiji Restoration and was a salient feature  of the Japanese national mindset until the end of World War II (1945).</p><p>bushmaster Species ( Lachesis muta) of pit viper, found in scrublands  and forests from Costa Rica south to the Amazon River basin. It is nor�  mally about 6 ft (1.8 m) long but reportedly may grow to twice this length.  It is pinkish or tan, marked with large, dark, diamond-shaped blotches.  Though seldom encountered, the bushmaster is potentially lethal.</p><p>Bushmen See San</p><p>business cycle Periodic fluctuation in the rate of economic activity, as  measured by levels of employment, prices, and production. Economists  have long debated why periods of prosperity are eventually followed by  economic crises (stock-market crashes, bankruptcies, unemployment,  etc.). Some have identified recurring 8-to-10-year cycles in market econo�  mies; longer cycles have also been proposed, notably by Nikolay Kon-  dratev. Apart from random shocks to the economy, such as wars and  technological changes, the main influences on the level of economic activ�  ity are investment and consumption. An increase in investment, as when a  factory is built, leads to consumption because the workers employed to  build the factory have wages to spend. Conversely, increases in consumer  demand cause new factories to be built to satisfy the demand. Eventually  the economy reaches its full capacity, and, with little free capital and no  new demand, the process reverses itself and contraction ensues. Natural  fluctuations in agricultural markets, psychological factors such as a band�  wagon mentality, and changes in the money supply have all been proposed  as explanations for initial changes in investment and consumption. After  World War II many governments used monetary policy to moderate the  business cycle, aiming to prevent the extremes of inflation and depression  by stimulating the national economy in slack times and restraining it dur�  ing expansions.

Such activities are usually the concern of senior managers, who  must use financial forecasting to develop a long-term plan for the firm.  Shorter-term budgets are then devised to meet the plan�s goals. When a  company plans to expand, it may rely on cash reserves, expected increases  in sales, or bank loans and trade credits extended by suppliers. Managers  may also decide to raise long-term capital in the form of either debt (bonds)  or equity (stock). The value of the company�s stock is a constant concern,  and managers must decide whether to reinvest profits or to pay dividends.  Other duties of financial managers include managing accounts receivable  and fixing the optimum level of inventories. When deciding how to deploy  corporate assets to increase growth, financial managers must also con�  sider the benefits of mergers and acquisitions, analyzing economies of  scale and the ability of businesses to complement each other.

It regulates various forms of legal business entities, including sole  proprietors, partnerships, registered companies with limited liability,  agents, and multinational corporations. Nearly all statutory rules govern�  ing business organizations are intended to protect creditors or investors.  In addition, specific bodies of law regulate commercial transactions,  including the sale and carriage of goods (terms and conditions, specific  performance, breach of contract, insurance, bills of lading), consumer  credit agreements (letters of credit, loans, security, bankruptcy), and rela�  tions between employers and employees (wages, conditions of work,</p><p>health and safety, fringe benefits, and trade unions).

April 1, 1866, Empoli, Tuscany�d. July 27, 1924, Berlin, Ger.)  Italian-born German composer and pianist. He first performed in public  at age 7, and at 12 he conducted his own Stabat Mater. He taught in Hel�  sinki, Moscow, and Boston before settling permanently in Berlin in 1894.  He won fame as a virtuoso pianist and gave premieres of the works of  major composers. His most celebrated work in his lifetime, the opera Die  Brautwahl (1910), was followed by the operas Arlecchino (1916) and  Turandot (1917), but the unfinished and posthumously produced Doktor  Faust is regarded as his masterpiece. Of his orchestral works, his piano  concerto (1904) is most widely performed. His many piano pieces include  the Fantasia contrappuntistica (1910), six sonatinas (1910-20), and  arrangements of organ works by Johann Sebastian Bach.</p><p>bustard Any of about 23 species of medium-sized to large game birds  in the family Otididae, related to the cranes and rails in the order Grui-  formes. Bustards are found in Africa, southern Europe, Asia, Australia,  and New Guinea. A tall running bird, they have long legs, a compact body  carried in a horizontal position, and an erect neck placed forward of the  legs. The best-known species is the great bustard (Otis tarda), the largest  European land bird. Males of this species weigh as much as 31 lbs (14  kg) and reach lengths of 4 ft (1.2 m), with 8-ft (2.4-m) wingspreads.</p><p>Bute, John Stuart, 3rd earl of orig. John Stuart (b.

He was elected head of the nonindependent black state of  KwaZulu in 1972 and revived Inkatha in 1975 after breaking with the  African National Congress (ANC). Rejecting full independence for Kwa�  Zulu, he worked within the white establishment to end apartheid. In  1990-94 he engaged in a fierce struggle for leadership with the ANC;  thousands were killed in Inkatha-ANC clashes. Following the 1994  national elections, he was appointed minister of home affairs by Nelson  Mandela; he held the post until 2004.</p><p>Butkus Vbot-kosV, Dick in full Richard J. Butkus (b.

A prominent  attorney in Lowell, Mass., Butler served two terms in the state legislature  (1853, 1859). In the American Civil War he commanded Fort Monroe, Va.,  where he refused to return fugitive slaves to the Confederacy, calling them  �contraband of war,� an interpretation later upheld by the government.  He oversaw the occupation of New Orleans in 1862 but was recalled  because of his harsh rule. He led the Union army in Virginia, but after  several defeats he was relieved of his command in 1865. In the U.S. House  of Representatives (1867-75, 1877-79), he was a Radical Republican  prominent in the impeachment trial of Pres. Andrew Johnson. He switched  parties in 1878 to support the Greenback movement and later served as  governor of Massachusetts (1882-84).</p><p>Butler, Joseph (b. May 18, 1692, Wantage, Berkshire, Eng.�d.

His works defended revealed religion against the rationalist think�  ers of his time. His The Analogy of Religion, Natural and Revealed, to  the Constitution and Course of Nature (1736) attacked the doctrine of  Deism, according to which knowledge of God is acquired through reason  rather than revelation.

He was the founding president of what  is today Columbia�s Teachers College (1886-91). As president of Colum�  bia University itself (1901�45), he led the institution to world renown.  Early in his career he criticized prevailing pedagogical methods, but later  he turned on pedagogical reform itself, decrying vocationalism in educa�  tion and behaviorism in psychology. A champion of international under�  standing, he helped establish the Carnegie Endowment for International  Peace in 1910 and served as its president (1925�45). In 1931 he shared  the Nobel Peace Prize with Jane Addams.</p><p>Butler, R(ichard) A(usten), baron of Saffron Walden (b. Dec.  9, 1902, Attock Serai, India�d.

As minister of education, he was responsible for the 1944 Educa�  tion Act, which established free secondary education. After the Tories�  electoral losses in 1945, he helped remold the Conservative Party, serv�  ing as its leader (1955-61). He served as chancellor of the exchequer  (1951-55), home secretary (1957-62), and foreign secretary (1963-64).</p><p>Butler, Samuel (b. Feb. 8, 1612, Strensham, Worcestershire, Eng.�d.  Sept. 25, 1680, London) British poet and satirist. He held several clerical  positions, where he could observe cranks and scoundrels like those whose  antics he targeted. He is famous for Hudibras (1663-78), a mock-heroic  poem skewering the fanaticism, pretentiousness, pedantry, and hypocrisy  he saw in militant Puritanism. It is the most memorable burlesque poem in  English and the first English satire that successfully attacked ideas rather  than personalities.</p><p>Butler, Samuel (b. Dec. 4, 1835,</p><p>Eng.�d.

He  is best known for The Way of All  Flesh (1903), his autobiographical  novel that tells, with ruthless wit and  lack of sentiment, the story of his  escape from the suffocating moral  atmosphere of his home circle. In his  lifetime his reputation rested on the  utopian satire Erewhon (1872),  which foreshadowed the end of the  Victorian illusion of eternal progress.</p><p>Buto Vbyu-to\ In ancient Egyptian  religion, the cobra goddess who was  tutelary goddess of Lower Egypt  and, with the vulture-goddess Nekh-  bet of Upper Egypt, protector of the  king.

Lying off the southeast coast of Celebes (Sulawesi), it is about 100 mi (160  km) long and has an area of about 2,000 sq mi (5,200 sq km). Its chief  town is Baubau, on the southwestern coast. The coastal people are chiefly  trading sailors and fishermen.</p><p>butte \'byiit\ (French: �hillock� or �rising ground�) Flat-topped hill sur�  rounded by a steep cliff, from the bottom of which a slope descends to  the plain. The term is sometimes used for an elevation higher than a hill  but not high enough to be a mountain. Buttes topped by horizontal plat�  forms of hard rock are characteristic of the arid plateau region of the  western U.S. A butte is similar to a mesa but generally smaller; both are  created by erosional processes.</p><p>butter Solid emulsion of fat globules and water made by churning cream,  used as a food. Presumably known since the advent of animal husbandry.</p><p>butter has long been used as a cooking fat and as a spread. It was tradi�  tionally a farm product, but with the advent of the cream separator in the  late 19th century it began to be mass-produced. It is a high-energy food,  containing about 715 calories per 100 grams. It is high in butterfat (80-  85%) and low in protein. Colouring is sometimes added to enhance its  natural yellow colour (from carotene), and salt is often added.</p><p>butter-and-eggs or toadflax Common perennial herbaceous plant  (Linaria vulgaris ) of the snapdragon family, native to Eurasia and widely  naturalized in North America. The plant bears flaxlike leaves and showy  yellow and orange flowers that are two-lipped and spurred like snap�  dragons.</p><p>buttercup Any of about 250 species of herbaceous flowering plants  constituting the genus Ranunculus of  the family Ranunculaceae. Butter�  cups are especially common in the  woods and fields of the northern tem�  perate zone. The turban, or Persian  buttercup ( R . asiaticus ), is the flo�  rist�s ranunculus. Among the many  wild species are the tall meadow but�  tercup ( R . acris) and common water  crowfoot (R. aquatilis). Other mem�  bers of the family Ranunculaceae are  widely distributed in all temperate  and subtropical regions. In the trop�  ics they occur mostly at high eleva�  tions. Their leaves are usually  alternate and stalkless and may be  simple or much divided. The flowers  may be radially symmetrical or  irregular. The family includes such  flowers as anemone, larkspur, marsh  marigold, clematis, and hepatica  (genus Hepatica).</p><p>butterfly Any of more than 17,000 lepidopteran species found world�  wide. Unlike moths, butterflies are active during the day and are usually  brightly coloured or strikingly patterned. Distinctive features are club-  tipped antennae and a habit of holding the wings vertically over the back  when at rest. With few exceptions the larvae and adults eat plants. But�  terflies are classified into five or six families. The metalmarks of the fam�  ily Lycaenidae are found chiefly in the New World tropics; some members  of the family Nymphalidae are called snout butterflies. Other species (with  their families) include the white and sulphur butterflies (Pieridae), the swal�  lowtail butterfly (Papilionidae), the blue, copper, and hairstreak butterflies  (Lycaenidae), and the admiral, monarch, and painted lady (Nymphalidae).</p><p>butterfly bush See buddleia  butterfly effect See chaotic behavior</p><p>butterfly weed North American plant ( Asclepias tuberosa ) of the milk�  weed family, a stout, rough-haired perennial with long horizontal roots. The  leafy, erect, somewhat branching stem is about 1-3 ft (0.3-0.9 m) tall. In  midsummer it bears numerous clusters of bright orange flowers. Unlike  most milkweeds, it has a scanty milky juice. It is native to dry fields and  is often planted in wild gardens or grown as a border plant.</p><p>butternut Deciduous NUT-producing tree (JugIans cinerea ) of the wal�  nut family, native to eastern North America. A mature tree has gray, deeply  furrowed bark. Each leaf has 11-17 yellowish green leaflets that are hairy  underneath. Chocolate-coloured partitions divide the pith of the twig into  many chambers. The egg-shaped fruit has a sticky, greenish brown husk.  The hard, woody nut bears many ridges and contains a sweet, oily seed.  The tree is economically important for its edible nuts and for a yellow or  orange dye obtained from the fruit husks. Some substances in the inner  bark of the roots are used in medicines.</p><p>button Small disk or knob used as a fastener or ornament. It usually has  holes or a shank through which it is sewn to one side of a garment. It is  used to fasten or close the garment when it is passed through a loop or  hole in the other side. The ancient Greeks fastened their tunics with but�  tons and loops. In medieval Europe, garments were laced or fastened  together with brooches or clasps until the buttonhole was reinvented in  the 13th century. Throughout history, buttons have been made in a range  of sizes and materials, some elaborated into miniature works of art.</p><p>Langar Rectory, Nottinghamshire,</p><p>Samuel Butler, detail of an oil painting  by Charles Gogin, 1896; in the  National Portrait Gallery, London.</p><p>COURTESY OF THE NATIONAL PORTRAIT GALLERY,  LONDON</p><p>Aquatic buttercup (Ranunculus  flabellaris).</p><p>FRANCES V.

He held two organist positions before being appointed organist at the  important Marienkirche in Liibeck (now in Germany), where he remained  for almost 40 years. There he reinstated the tradition of the Abendmusik,  an annual series of church concerts. His reputation was such that in 1705  Johann Sebastian Bach traveled 200 miles there to hear him play and ended  up staying three months. Buxtehude�s approximately 130 surviving vocal  works, usually called cantatas, can instead be classified as concertos, cho�  rale settings, and arias. All are imbued with a devout simplicity that con�  trasts strongly with the elaborations of their Bachian successors. He also  composed almost 100 works for organ, some 20 keyboard suites, and more  than 20 chamber sonatas.</p><p>Buyid \'bu-yid\ dynasty or Buwayhid \bii-'wl-hid\ dynasty  (945-1055) Muslim ShTite dynasty founded by three sons of Buyeh, a  Daylamite (north Persian) fisherman. They captured Baghdad in 945, and  each brother took a portion of territory. After they died, one Buyid leader,  c Adud al-Dawlah, consolidated control (977) and enlarged the Buyid  domain. From 983 the territories were split among family members. The  dynasty ended when the Turkic Seljuq dynasty took Baghdad in 1055.  Buyid art maintained its influence throughout the Seljuq reign; Buyid sil-  verwork is notable.</p><p>buzkashi Persian "goat dragging" An equestrian game in which  riders compete to gain control of a goat or calf carcass that has been  decapitated and dehoofed. Buzkashi likely originated as an entertaining  variant of ordinary herding or raiding. It is popular predominantly among  Turkic peoples in Afghanistan but can be found in the Muslim republics  of Central Asia and in parts of northwestern China. Buzkashi has two main  forms. The traditional version, tudabaray, has no formal teams and is not  played within clearly defined boundaries. Games often involve hundreds  of riders, and the objective is to gain sole possession of the carcass and  ride it free and clear of all other riders. The modern government-sponsored  qarajay style involves two teams of 10-12 riders that contend on a defined  field with goals. Beginning in the early 1950s, the Kabul-based Afghan  government hosted national tournaments.</p><p>buzz bomb See V-l missile</p><p>buzzard Chiefly British term for any of several birds of prey of the hawk  genus Buteo (family Accipitridae) and, in North America, various New  World vultures, especially the turkey vulture. In Australia, a large hawk of  the genus Hamirostra is called a black-breasted buzzard. The buteos, also  called buzzard hawks, can usually be distinguished when soaring by their  broad wings and expansive rounded tail. The plumage of most species is  dark brown above and white or mottled brown below; the tail and under�  side of the wings are usually barred. Buteos customarily prey on insects,  small mammals, and occasionally birds. They nest in trees or on cliffs.  Species range over much of the New World, Eurasia, and Africa. The red�  tailed hawk, the most common North American buteo, is about 2 ft (60  cm) long.</p><p>Buzzards Bay Inlet of the Atlantic Ocean, southeastern Massachusetts,  U.S. Connected to Cape Cod Bay by the Cape Cod Canal on the north�  east and bordered on the southeast by the Elizabeth Islands, it is 30 mi  (48 km) long and 5-10 mi (8-16 km) wide.

Located north of Beirut, Leb., the site was  occupied by at least the Neolithic Period (New Stone Age); extensive settle�  ment developed during the 4th millennium bc. As the chief harbour for  the export of cedar to Egypt, it was a great trading centre. Papyrus, an  early writing surface produced in Egypt, received its original Greek name,  byblos, from its export to the Aegean through the city; the English word  Bible means essentially �the (papyrus) book.� Almost all known early  Phoenician inscriptions, most from the 10th century bc, come from By�  blos. By that time Tyre had become the preeminent city in Phoenicia, and,  though Byblos continued to flourish into Roman times, it never recovered  its former supremacy.</p><p>Bydgoszcz \'bid-,g6shch\ City (pop., 2000 est.: 384,500), northern  Poland. Originally a commercial city of the Teutonic Order, it received  town rights in 1346. It prospered as a grain and timber centre until it was  devastated in the 17th-century Swedish wars. In the 18th century the  Bydgoszcz Canal, which linked the basins of the Vistula and Oder rivers,  made the city a major inland port. It fell under Prussian rule in 1772-  1919. The Germans held it throughout World War II, but it was noted for  its staunch resistance to the Nazi invasion of 1939.

After serving in World War I, he worked developing navigational  aids for aircraft. In 1926 he and Floyd Bennett claimed to have reached  the North Pole by airplane, becoming the first to do so. In 1928 Byrd  began his explorations of Antarctica with the first expedition to his �Little  America� base, which was followed in 1929 by a flight with three com�  panions over the South Pole, again the first such flight. He led subsequent  expeditions that discovered and mapped large areas of Antarctica. His  several books include Discovery (1935) and Alone (1938), which  chronicled his months spent alone in a camp near the South Pole. His  brother Harry F.

In 1575  the two men received from Elizabeth I the exclusive license for the print�  ing and selling of music in Britain. Though repeatedly prosecuted as a  Roman Catholic, Byrd remained in favour with the queen. He is renowned  as Britain�s finest composer of sacred choral works, as well as for his  keyboard music and songs. His works include three masses (for three,  four, and five voices), some 220 Latin motets, four important Anglican  services, and some 60 anthems, as well as some 100 virginal pieces (many  preserved in the collections Parthenia and The Fitzwilliam Virginal Book).</p><p>Byrne, David (b.

At the Rhode Island School of  Design in the mid-1970s, he cofounded the rock group Talking Heads as  singer and guitarist. Identified with the new wave movement (see punk),  the band�s debut album Talking Heads �77 (1977) was followed by  releases that reflected Byrne�s interest in experimental pop and African  rhythms, including Speaking in Tongues (1983), Stop Making Sense  (soundtrack for film of the same name; 1984), and solo albums such as  Rei Momo (1989).

Educated at Cambridge, he gained recognition with  English Bards and Scotch Reviewers (1809), a satire responding to a criti�  cal review of his first published volume, Hours of Idleness (1807). Childe  Harold�s Pilgrimage (1812-18), a poetic travelogue expressing melan�  choly and disillusionment, brought him fame, while his complex person�  ality, dashing good looks, and many scandalous love affairs, with women  and with boys, captured the imagination of Europe. Settling near Geneva,  he wrote the verse tale The Prisoner of Chillon (1816), a hymn to liberty  and an indictment of tyranny, and Manfred (1817), a poetic drama whose  hero reflected Byron�s own guilt and frustration. His greatest poem, Don  Juan (1819-24), is an unfinished epic picaresque satire in ottava rima.  Among his numerous other works are verse tales and poetic dramas. He  died of fever in Greece while aiding the struggle for independence, mak�  ing him a Greek national hero.</p><p>byssinosis \,bi-s3-'no-s3s\ or brown lung disease Respiratory dis�  order caused by dust from cotton and other fibres, common among tex�  tile workers. In addition, the dust stimulates histamine release; air passages  constrict, making breathing difficult. Over time the dust accumulates in  the lung, producing a typical brown discoloration. Byssinosis today is  seen in most cotton-producing regions of the world. Several years of  exposure to cotton dust are needed before byssinosis develops. In  advanced stages, it causes chronic, irreversible obstructive lung disease.  Though cotton is by far the most common cause, flax, hemp, and other  organic fibres can also produce byssinosis. There is evidence that a bac�  terial product found in the fibres is the cause of the disease.</p><p>byte See bit</p><p>Byzantine architecture Vbi-zon-.tenV Building style of Constantino�  ple (now Istanbul, formerly ancient Byzantium) after ad 330.

The most distinctive feature was the domed roof.  To allow a dome to rest above a square base, either of two devices was  used: the squinch (an arch in each of the comers of a square base that  transforms it into an octagon) or the pendentive. Byzantine structures fea�  tured soaring spaces and sumptuous decoration: marble columns and  inlay, mosaics on the vaults, inlaid-stone pavements, and sometimes gold  coffered ceilings. The architecture of Constantinople extended throughout  the Christian East and in some places, notably Russia, remained in use  after the fall of Constantinople (1453). See also Hagia Sophia.</p><p>Byzantine art Art associated with the Byzantine Empire. Its character�  istic styles were first codified in the 6th century and persisted with remark�  able homogeneity until the capture of Constantinople by the Turks in  1453. Concerned almost exclusively with religious expression, it tends to  reflect an intensely hierarchical view of the universe. It relies on vigour  of line and brilliance of colour; individual features are absent, forms are  flattened, and perspective is absent. Walls, vaults, and domes were cov�  ered in mosaic and fresco decoration in a total fusion of architectural and  pictorial expression. Byzantine sculpture was largely limited to small  ivory reliefs. The importance of Byzantine art to European religious art  was immense; the style was spread by trade and expansion to the Medi�  terranean basin, eastern European centres, and especially Russia. See also  Byzantine architecture.</p><p>Byzantine chant Unison liturgical chant of the Greek Orthodox church  from the era of the Byzantine Empire to the 16th century. It probably derived  principally from Hebrew and Syrian Christian liturgies. A system of eight  modes, very similar to the eight Greek modes, was used for psalms and  hymns, each mode (or echos) consisting primarily of a few melodic for�  mulas. The principal hymn genres were the troparion (one or more stan�  zas of poetic prose), the kontakion (a metrical sermon), and the kanon (a  complexly ordered set of hymn types). See also Gregorian chant.</p><p>Byzantine Empire Empire, southeastern and southern Europe and  western Asia. It began as the city of Byzantium, which had grown from  an ancient Greek colony founded on the European side of the Bosporus.  The city was taken in ad 330 by Constantine I, who refounded it as Con�  stantinople. The area at this time was generally termed the Eastern Roman  Empire. The fall of Rome in 476 ended the western half of the Roman  Empire; the eastern half continued as the Byzantine Empire, with Con�  stantinople as its capital. The eastern realm differed from the west in many  respects: heir to the civilization of the Hellenistic era, it was more com-</p><p>Byzantine Emperors</p><p>Zeno</p><p>474-491</p><p>Theodora ( empress)</p><p>1055-56</p><p>Anastasius 1</p><p>491-518</p><p>Michael VI Stratioticus</p><p>1056-57</p><p>Justin 1</p><p>518-527</p><p>Isaac 1 Comnenus</p><p>1057-59</p><p>Justinian 1</p><p>527-565</p><p>Constantine X Ducas</p><p>1059-67</p><p>Justin II</p><p>565-578</p><p>Romanus IV Diogenes</p><p>1067-71</p><p>Tiberius II Constantine</p><p>578-582</p><p>Michael VII Ducas</p><p>1071-78</p><p>Maurice Tiberius</p><p>582-602</p><p>Nicephorus III Botaniates</p><p>1078-81</p><p>Phocas</p><p>602-610</p><p>Alexius 1 Comnenus</p><p>1081-1118</p><p>Heraclius</p><p>610-641</p><p>John II Comnenus</p><p>1118-43</p><p>Heraclius Constantine</p><p>641</p><p>Manuel 1 Comnenus</p><p>1143-80</p><p>Heraclonas (or Heraclius)</p><p>641</p><p>Alexius II Comnenus</p><p>1180-83</p><p>Constans II (Constantine</p><p>641-668</p><p>Andronicus 1 Comnenus</p><p>1183-85</p><p>Pogonatus)</p><p>Isaac II Angelus</p><p>1185-95</p><p>Constantine IV</p><p>668-685</p><p>Alexius III Angelus</p><p>1195-1203</p><p>Justinian II Rhinotmetus</p><p>685-695</p><p>Isaac II Angelus ( restored)</p><p>1203-4</p><p>Leontius</p><p>695-698</p><p>&amp; Alexius IV Angelus</p><p>Tiberius III</p><p>698-705</p><p>Alexius V Ducas</p><p>1204</p><p>Justinian II Rhinotmetus</p><p>705-711</p><p>Murtzuphlus</p><p>( restored)</p><p>Latin emperors</p><p>Philippicus</p><p>711-713</p><p>Baldwin 1</p><p>1204-5</p><p>Anastasius II</p><p>713-715</p><p>Henry</p><p>1206-16</p><p>Theodosius III</p><p>715-717</p><p>Peter</p><p>1217</p><p>Leo III</p><p>717-741</p><p>Yolande (empress)</p><p>1217-19</p><p>Constantine V</p><p>741-775</p><p>Robert</p><p>1221-28</p><p>Copronymus</p><p>Baldwin II</p><p>1228-61</p><p>Leo IV</p><p>775-780</p><p>John</p><p>1231-37</p><p>Constantine VI</p><p>780-797</p><p>Nicaean emperors</p><p>Irene ( empress )</p><p>797-802</p><p>Constantine (XI)</p><p>1204-5?</p><p>Nicephorus 1</p><p>802-811</p><p>Theodore 1 Lascaris</p><p>1205?-22</p><p>Stauracius</p><p>811</p><p>John III Ducas Vatatzes</p><p>1222-54</p><p>Michael 1 Rhangabe</p><p>811-813</p><p>Theodore II Lascaris</p><p>1254-58</p><p>Leo V</p><p>813-820</p><p>John IV Lascaris</p><p>1258-61</p><p>Michael II Balbus</p><p>820-829</p><p>Greek emperors restored</p><p>Theophilus</p><p>829-842</p><p>Michael VIII</p><p>1261-82</p><p>Michael III</p><p>842-867</p><p>Palaeologus</p><p>Basil 1</p><p>867-886</p><p>Andronicus II</p><p>1282-1328</p><p>Leo VI</p><p>886-912</p><p>Palaeologus</p><p>Alexander</p><p>912-913</p><p>Andronicus III</p><p>1328-41</p><p>Constantine VII</p><p>913-959</p><p>Palaeologus</p><p>Porphyrogenitus</p><p>John V Palaeologus</p><p>1341-76</p><p>Romanus 1 Lecapenus</p><p>920-944</p><p>John VI Cantacuzenus</p><p>1347-54</p><p>Romanus II</p><p>959-963</p><p>Andronicus IV</p><p>1376-79</p><p>Nicephorus II Phocas</p><p>963-969</p><p>Palaeologus</p><p>John 1 Tzimisces</p><p>969-976</p><p>John V Palaeologus</p><p>1379-90</p><p>Basil II Bulgaroctonus</p><p>976-1025</p><p>( restored)</p><p>Constantine VIII</p><p>1025-28</p><p>John VII Palaeologus</p><p>1390</p><p>Romanus III Argyrus</p><p>1028-34</p><p>John V Palaeologus</p><p>1390-91</p><p>Michael IV</p><p>1034-41</p><p>( restored)</p><p>Michael V Calaphates</p><p>1041-42</p><p>Manuel II Palaeologus</p><p>1391-1425</p><p>Zoe ( empress )</p><p>1042-50</p><p>John VIII Palaeologus</p><p>1421-48</p><p>Constantine IX</p><p>1042-55</p><p>Constantine XI</p><p>1449-53</p><p>Monomachus</p><p>Palaeologus</p><p>*For emperors of the Eastern Roman Empire (at Constantinople) before the  fall of Rome, see Roman republic and empire.</p><p>mercial and more urban. Its greatest emperor, Justinian (r. 527-565),  reconquered some of western Europe, built the Hagia Sophia, and issued  the basic codification of Roman law. After his death the empire weak�  ened. Though its rulers continued to style themselves �Roman� long after  Justinian�s death, �Byzantine� more accurately describes the medieval  empire. The long controversy over iconoclasm within the eastern church  prepared it for the break with the Roman church (see Schism of 1054).  During the controversy, Arabs and Seljuq Turks increased their power in  the area. In the late 11th century, Alexius I Comnenus sought help from  Venice and the pope; these allies turned the ensuing Crusades into plun�  dering expeditions. In the Fourth Crusade the Venetians took over Con�  stantinople and established a line of Latin emperors. Recaptured by  Byzantine exiles in 1261, the empire was now little more than a large  city-state. In the 14th century the Ottoman Turks began to encroach; their  extended siege of Constantinople ended in 1453, when the last emperor  died fighting on the city walls and the area came under Ottoman control.</p><p>Byzantium See Istanbul</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>306 I C &#x25BA; cable structure</p><p>C High-level procedural computer programming language with many low-  level features, including the ability to handle memory addresses and bits.

The cabaret  probably originated in France in the 1880s as a small  club that presented amateur acts and satiric skits lam�  pooning bourgeois conventions. The first German  Kabarett was opened in Berlin c. 1900 by Baron Ernst  von Wolzogen and accompanied its musical acts with  biting political satire. By the 1920s it had become the  centre for underground political and literary expression  and a showcase for the works of social critics such as Be  tolt Brecht and Kurt Weill; this decadent but fertile artistic milieu  was later portrayed in the musical Cabaret (1966; film, 1972). The  English cabaret derived from concerts given in city taverns in the 18th�  19th centuries and evolved into the music hall. In the U.S. the cabaret  developed into the nightclub, where comedians, singers, or musicians  performed. Small jazz and folk clubs and, later, comedy clubs evolved  from the original cabaret.</p><p>cabbage Leafy garden plant ( Brassica oleracea, Capitata group) of  European origin, with a short stem and a globular head of usually green  leaves. A member of the mustard family, it is a major table vegetable in most  countries of the temperate zone. The term cabbage also refers more gen�  erally to a vegetable and fodder plant of various horticultural forms devel�  oped by long cultivation from the wild, or sea, cabbage ( B. oleracea)  found near the seacoast in England and continental Europe. The common  forms may be classified by the plant parts used for food: leaves (e.g., KALE,  collard, common cabbage, Brussels sprout); flowers and flower stalks (e.g.,  broccoli, cauliflower); and stems (e.g., kohlrabi). Cabbages grow best in  mild to cool climates and tolerate frost. Edible portions are low in caloric  value and are an excellent source of vitamin C, minerals, and dietary fibre.  See also Chinese cabbage.</p><p>cabbage looper Distinctive green, white-lined larva, or caterpillar  {Trichoplusia ni), of the owlet MOTH family (Noctuidae).

His other works, many of them alle�  gories set in an imaginary medieval province, include The Cream of the  Jest (1917) and The High Place (1923).

The bicycle-wheel roof involves two layers of tension cables  radiating from an inner tension ring and an outer compression ring, which  in turn is supported by columns.</p><p>cable television System that distributes television signals by means of  coaxial or fibre-optic cables. Cable television systems originated in the U.S.  in the early 1950s to improve reception in remote and hilly areas, where  broadcast signals were weak. In the 1960s they were introduced in large  metropolitan areas where reception is sometimes degraded by reflection  of signals from tall buildings. Since the mid-1970s there has been a pro�  liferation of cable systems that offer special services and which generally  charge a monthly fee. Besides providing high-quality signals, some sys�  tems can deliver hundreds of channels. Another feature increasingly  offered by cable operators is two-way, interactive communication by  which viewers can, for example, participate in public-opinion polls as well  as connect to the Internet. Cable operators are also involved in the devel�  opment of video compression, digital transmission, and high-definition tele�  vision.</p><p>Cabot, George (b. Jan. 16, 1752, Salem, Mass.�d.

These two  processes are sometimes grouped as CAE (computer-aided engineering).</p><p>Cadbury, George (b. Sept. 19, 1839, Birmingham, Warwickshire,  Eng.�d. Oct. 24, 1922, Birmingham) British businessman and social  reformer. In 1861 he and his brother Richard took over their father�s fail�  ing business and built it into the highly prosperous Cadbury Brothers  cocoa- and chocolate-manufacturing firm. They improved working con�  ditions and introduced a private social security program for employees.  George was also noted for his successful experiments in housing and town  planning in Bournville, where he built affordable working-class homes  with large gardens.</p><p>caddis fly Any member of about 7,000 species of mothlike aquatic  insects (order Trichoptera) found worldwide, usually in freshwater habi�  tats but sometimes in brackish and tidal waters. Generally dull brownish,  caddis flies have long antennae and hairy wings that fold rooflike over the  abdomen. They feed primarily on plant juices and flower nectar, though  a few are predaceous. Many caddis-fly larvae construct a portable case  from grains of sand, bits of shells, and plant debris glued together by a  sticky substance they secrete. This case surrounds the larva�s abdomen  while it matures. Caddis flies are important to freshwater ecosystems  because they clean the water by consuming plant and animal debris and  serve, as larvae and adults, as an important food for fish, particularly trout.</p><p>Caddo One of a group of North American Indian people living mostly  in western Oklahoma, U.S. Their  language is of the Caddoan language  family. Their name derives from a  French truncation of kadohadacho,  meaning �real chief� in Caddo. From  ancient times they occupied the  lower Red River area in Louisiana  and Arkansas, and many striking  examples of prehistoric pottery and  basketry have been found. They  were a semisedentary agricultural  people who lived in conical pole-  and-thatch dwellings. In the 18th  century pressures from white settlers  pushed many Caddo off their lands,  a process that intensified with the  Louisiana Purchase in 1803. By 1835  the Caddo had ceded all their land to the U.S., and by 1859 most were  living on reservations in Oklahoma. Some 2,700 Caddo claimed sole  Caddo descent in the 2000 U.S. census.</p><p>Cade's Rebellion (1450) Uprising against the government of Henry  VI of England. Jack Cade, an Irishman of uncertain occupation living in  Kent, organized a rebellion among local small property holders angered  by high taxes and prices. He took the name John Mortimer, identifying</p><p>himself with the family of Henry�s rival, the duke of York. Cade and his  followers defeated a royal army in Kent and entered London, where they  executed the lord treasurer. They were soon driven out of the city; Cade�s  followers dispersed on being offered a pardon, and Cade was mortally  wounded in Sussex. His rebellion contributed to the breakdown of royal  authority that led to the Wars of the Roses.</p><p>Cadiz \ko-'diz,\ Spanish Vka-thes\ City (pop., 2001: city, 133,363; metro,  area, 400,157), southwestern Spain. Located on a peninsula in the Bay of  Cadiz northwest of Gibraltar, it is the main seaport of Cadiz province in  Andalusia. Founded as Gadir by Phoenicians from Tyre c. 1100 bc, it was  later ruled by Carthage, Rome (as Gades), and the Visigoths. It was held  by the Moors beginning in ad 711. In 1262 Cadiz was captured by Alfonso  X of Castile-Leon. The city enjoyed great prosperity as a centre for Span�  ish trade with the American colonies in the 16th�18th centuries (see  Sevilla). It now has naval and mercantile shipbuilding yards.</p><p>Cadiz, Bay of Inlet of the Gulf of Cadiz, southwestern Spain. An inlet  indenting the coast of Cadiz province, it receives the Guadalete River and  is partially protected by the Isle of Leon, on which the port of Cadiz is  located. The Spanish-U.S. air and naval base at Rota is situated on the bay.</p><p>cadmium Metallic chemical element, chemical symbol Cd, atomic num�  ber 48. It normally occurs along with other metals, especially zinc, in ores.  A silvery white metal capable of taking a high polish, cadmium does not  corrode under alkaline (see alkali) conditions; one of its major uses is in  electroplating other metals and alloys to protect them. Because it absorbs  neutrons effectively, it is used in control rods in some nuclear reactors.  Its compounds, in which it has valence 2, are very toxic. They are used  as pigments, as phosphors in television and computer monitor screens, as  pesticides, and in photographic applications and analytical chemistry.</p><p>Cadmus In Greek mythology, the son of the king of Phoenicia, brother  of Europa, and founder of Thebes. When Zeus carried off Europa, Cadmus  was sent to find her. The Delphic oracle ordered him to end his search,  follow a cow, and build a town where it lay down. That town became  Thebes. He built the citadel of Thebes with the help of fierce armed men  who sprang up where he sowed the teeth of a dragon he had slain. He  married Harmonia, daughter of Ares and Aphrodite, and their five children  included Semele. Cadmus was said to have brought the alphabet to Greece.</p><p>Cadogan \k9-'d9g-9n\, William, 1st Earl (b. 1672, Liscarton,  County Meath, Ire.�d. July 17, 1726, Kensington, near London, Eng.)  British soldier. He served as a trusted colleague with the duke of Marl�  borough in the War of the Spanish Succession. Later he became involved  in intrigues to secure the succession for the Hanoverian George I (1714).  He crushed a Jacobite rebellion in 1716, was granted an earldom in 1718,  and was promoted to commander in chief in 1722.</p><p>caduceus \k9-'du-se-9s\ Staff carried by Hermes as a symbol of peace. It  served as a badge of protection for ancient Greek and Roman heralds and  ambassadors. It was originally depicted as a rod or olive branch ending in  two shoots and decorated with garlands or ribbons; in later iconography  the garlands became two snakes and a pair of wings was attached to the  staff to represent Hermes� speed. The caduceus was adopted as a symbol  of physicians because of its similarity to the staff of Asclepius.</p><p>caecilian \si-'sil-y9n\ Any of 155 species of wormlike amphibians found  in humid regions from Mexico to northern Argentina and in Africa, South�  east Asia, and the Seychelles. The elongate, ringed, limbless body is 4-60  in. (10-150 cm) long. Colour ranges from blackish to pinkish tan. The tiny  eyes are covered by skin and often by bone. A chemosensory projection lies  between the eye and nostril. Some species lay eggs, which are guarded by  the female and hatch into free-living larvae; other species bear live young.  Caecilians spend their lives underground and eat worms and insects.</p><p>Caecus, Appius Claudius See Appius Claudius Caecus</p><p>Caedmon Ykad-msnX (fl. 658-680) Earliest known Old English Chris�  tian poet. According to Bede, he was a herdsman who received a divine  call in a dream to sing of �the beginning of things� and began to utter  �verses which he had never heard.� He entered a monastery, where he  produced vernacular poetry on sacred themes expounded to him by more  learned brethren. Only the nine-line original dream hymn can be confi�  dently attributed to him, but it set the pattern for almost all of Anglo-  Saxon religious verse.</p><p>Caen Vka n \ City (pop., 1999: 113,987), northwestern France.

The English took it in 1346 and 1417 and held it until 1450. It suf�  fered in the Wars of Religion and fell to the Protestants in 1562. During  the French Revolution it was a centre for the Girondin movement. The city  was severely damaged in the Allied Normandy Campaign (1944), but it  was rebuilt. Notable structures include the 11th-century abbey and the  university. Caen is a transportation centre and manufactures automobiles  and electrical equipment.</p><p>Caere \'k!-ra\ Ancient city, Etruria. Located northwest of Rome near the  modern city of Ceveteri, it was an  important trading centre. Brought  under Roman control in 253 bc, it  prospered as part of the empire but  declined in later centuries. The  derived Latin word caeremonium  (source of English ceremony) reflects  the Etruscan fascination with divina�  tion and prophecy. Tomb chambers  have yielded gold and silver objects,  which show an Orientalizing ten�  dency in the Etruscan art of the 7th  century bc.</p><p>CaernarfonVklr-'nar-vo^kar-'nar-  von\ Town (pop., 2001: 9,611),  administrative centre of Gwynedd  county and county seat of the historic  county of Caernarvonshire, Wales.</p><p>Located near the west end of the  Menai Strait, it was the site of a  Roman fort, Segontium, built c. ad  75. After the Roman withdrawal (c.</p><p>380-390), it was the seat of local chieftains. The township was completely  transformed by Edward I after his conquest of Wales in 1282-83. The  imposing castle he built (birthplace of his son Edward II) has been pre�  served, and since 1911 it has been the site of the investiture of the prince  of Wales.</p><p>Caesar, Irving orig. Isidor Caesar (b. July 4, 1895, New York,  N.Y., U.S.�d. Dec. 18, 1996, New York City) U.S. lyricist. Caesar  worked with Henry Ford during World War I before turning to songwrit�  ing. Working with various collaborators, he provided the lyrics for such  standards as �Swanee,� �Sometimes I�m Happy,� �Crazy Rhythm,� and  �Tea for Two,� one of the most frequently recorded tunes ever written.</p><p>Caesar, (Gaius) Julius (b. July 12/13, 100, Rome�d. March 15, 44  bc, Rome) Celebrated Roman general, statesman, and dictator. A patrician  by birth, he held the prominent posts of quaestor and praetor before  becoming governor of Farther Spain in 61-60. He formed the First Tri�  umvirate with Pompey and Marcus Licinius Crassus in 60 and was elected  consul in 59 and proconsul in Gaul and Illyria in 58. After conducting the  Gallic Wars, during which he invaded Britain (55, 54) and crossed the  Rhine (55, 53), he was instructed by the Senate to lay down his com�  mand, Senate conservatives having grown wary of his increasing power,  as had a suspicious Pompey. When the Senate would not command  Pompey to give up his command simultaneously, Caesar, against regula�  tions, led his forces across the Rubicon River (49) between Gaul and Italy,  precipitating the Roman Civil War. Pompey fled from Italy but was pur�  sued and defeated by Caesar in 48; he then fled to Egypt, where he was  murdered. Having followed Pompey to Egypt, Caesar became lover to  Cleopatra and supported her militarily. He defeated Pompey�s last sup�  porters in 46-45. He was named dictator for life by the Romans. He was  offered the crown (44) but refused it, knowing the Romans� dislike for  kings. He was in the midst of launching a series of political and social  reforms when he was assassinated in the Senate House on the ides of  March by conspirators led by Cassius and Brutus. His writings on the Gal�  lic and Civil wars are considered models of classical historiography.</p><p>Caesar, Sid (b. Sept. 8, 1922, Yonkers, N.Y., U.S.) U.S. comedian. He  began his career as a band musician but switched to comedy. Noted for  his pantomime skills and his ability to mimic foreign languages at high  speed, he performed comic routines in live television shows and costarred  with Imogene Coca (1908-2001) and Carl Reiner in the popular comedy  variety program Your Show of Shows (1950-54). He created his own Cae�  sar�s Hour (1954-57) and later appeared in television specials.</p><p>Caesar Augustus See Caesar Augustus</p><p>Caesarea V.se-zo-'re-oX modern Horbat Qesari Vk6r-bat-'ka-sa-re\  Ancient seaport, Palestine. Located on the coast of present-day Israel south  of the city of Haifa, it was originally a Phoenician settlement. Taken by  the Romans and rebuilt in the 1st century bc by Herod the Great, it was  renamed for his patron Augustus. The capital of the Roman province of  Judaea in ad 6, it was the site of an early Christian church and was often  visited by St. Paul.

It is often associated with the Byzantine Empire, where  emperors presided over church councils and appointed patriarchs. The  term has also been applied to other historical eras, including the rule of  Tsar Peter I, who made the Russian Orthodox Church a department of the  state, and the reign of Henry VIII in England.</p><p>caffeine Heterocyclic comfound that, like other alkaloids, has marked  physiological effects. It occurs in coffee beans, tea leaves, kola nuts,  cacao, mate, and guarana and in the products made from them. Its stimu�  lating effect on the central nervous system, heart, cardiovascular system, and  kidneys makes it medically useful in treating respiratory depression caused  by overdose of barbiturates, morphine, or heroin. Its positive effects can  include improved motor performance, decreased fatigue, increased alert�  ness, and enhanced sensory activity. Excessive caffeine can produce irri�  tability, anxiety, insomnia, and potentially serious symptoms such as heart  irregularities and delirium. Much of the caffeine included in many over-  the-counter stimulants, cold remedies, and painkillers has been extracted  during production of decaffeinated coffee and tea.</p><p>Cagayan de Oro X.ka-ga-'yan-da-'o-roX City (pop., 2000: 461,877),  northern Mindanao, Philippines.

U.S. avant-  garde composer and writer. The son of an inventor. Cage studied music  with Arnold Schoenberg and Henry Cowell. From the early 1940s he was  closely associated with the choreographer Merce Cunningham. Though he  began as a 12-tone composer (see serialism), by 1943 his sonic experiments  had marked him as notably original. He soon turned to Zen Buddhism  and concluded that all activities that make up music are part of a single  natural process and that all sounds are potentially musical; thenceforth he  advocated indeterminism and endeavoured to ensure randomness in his  works, using increasingly inventive notation and often relying on the  Confucian classic Yijing. By the 1960s he had expanded into the realm of  multimedia. His disparate works include Bacchanale for prepared piano  (1938), Imaginary Landscape No. 4 for 12 radios (1951), Fontana Mix  for tape (1958), HPSCHD for seven harpsichords, 51 tapes, and nonmu�  sical media (1969), and Roaratorio (1979). His widely read books include  Silence (1961), A Year from Monday (1967), Notations (1969), and M  (1973). His international influence was far greater than that of any pre�  vious American composer.</p><p>Cagliari Vkal-ya-re\ ancient Caralis City (pop., 2001 prelim.:  158,351), capital of Sardinia, Italy. Located on the southern coast of the  island of Sardinia, Cagliari was founded by the Phoenicians.

He was named premier in 1911 but  was forced to resign after negotiating a controversial treaty with Germany  over the second of the Moroccan crises. Later his opposition to World  War I and friendship with German agents led to conviction on charges of  corresponding with the enemy. Granted amnesty in 1924, he was later  elected to the Senate and became head of the Commission of Finance  (1927^10).</p><p>Caillebotte \ka-y9-'bot\, Gustave (b. Aug. 19, 1848, Paris, Fr.�d.

He pursued his  interest in painting at the Ecole des Beaux-Arts and became a prolific  painter of contemporary subjects, town and country views, still lifes, and  boating scenes. In Caillebotte�s masterpiece, Paris Street; Rainy Day  (1877), he used bold perspective to create a monumental portrait of a Paris  intersection. In addition to his own painting, Caillebotte was the chief  organizer, promoter, and financial backer of the Impressionist exhibitions,  and he purchased works by Edouard Manet, Edgar Degas, Claude Monet,  Paul Cezanne, and others. He bequeathed his collection to the state, and  in 1897 it formed the basis of the first Impressionist exhibition in a French  museum.

Cairo�s newer section (Al-Qahirah) was built by the Fatimid  dynasty (c. 968) and was made the capital in 973. From the 13th century,  as the capital of the MamlOk dynasty, it reached its greatest prosperity as  a trade and cultural centre. Occupied by French forces under Napoleon I  in 1798, it was held by the French for three years. In World War II (1939�  45) it was a base of operations for British and U.S. forces and was also  the site of two conferences by the Allied Powers (see Cairo conferences).  The ancient metropolis is a blend of old and new. East and West. It is the  centre of the largest urban agglomeration in the Middle East and Africa,  and it is the chief cultural centre of the Arab world. Its most noteworthy  landmark is the pyramid complex of Giza, located at the southwestern  edge of the city.

While on a  pilgrimage to perform his father�s death-anniversary ceremony, he had a  profound religious experience, and he returned home indifferent to  worldly matters. Disciples joined him in worship that consisted of choral  singing of the name of God, often accompanied by dance movements and  ending in trance states. He took his new name on initiation as an ascetic  in 1510. In his lifetime his following came to constitute a major sect of  Vaishnavism (see Caitanya movement). According to tradition, he died when  he walked into the ocean while lost in a devotional trance.</p><p>Caitanya movement Emotional form of Hinduism that developed in  the 16th century, inspired by the mode of worship originated by Caitanya.  Centred in Bengal, the movement was organized by Caitanya�s followers  Nityananda and Advaita. Bhakti (devotion) is central and takes the form  of singing for hours, with accompaniment, hymns that repeat God�s name.  Caitanya himself came to be worshiped as an incarnation of both Krishna  and his beloved, Radha. Caitanya, Nityananda, and Advaita are regarded  as the movement�s three masters. A group of six of Caitanya�s disciples  developed its theology and devotional literature. Its present leaders are  mostly lineal descendants of the early disciples.

Originally a fishing  village built on an island, it was  improved by the count of Flanders in  997 and fortified by the count of  Boulogne in 1224. Calais was taken  in 1347 by Edward III of England, and  after 1450 it was the only remaining  English possession in France. The  2nd duke de Guise took Calais from  the English in 1558. In World War II it was a main objective in the Ger�  man drive to the sea in 1940. It is an important passenger port and is near  the French terminus of the Channel Tunnel. The city is famous for its lace  and embroideries.</p><p>Calamity Jane orig. Martha Jane Cannary (b. May 1, 1852?,  near Princeton, Mo.?, U.S.�d.

It was founded in  1158 by two Cistercian monks who  proclaimed a holy Crusade to defend  the city of Calatrava against the  Moors. By the 15th century the order had 200,000 members and became  increasingly involved in Castilian domestic politics. In 1489 it was incor�  porated into the crown by Ferdinand V and Isabella I, who deemed that all  private armies had outserved their usefulness. It remained an honorary  association of Spanish nobles until its dissolution in the 19th century.</p><p>calcedony See chalcedony</p><p>calcite Vkal-,slt\ Most common form of natural calcium carbonate  (CaC0 3 ), a widely distributed mineral known for the beautiful develop�  ment and great variety of its crystals. It occurs in stalagmites and stalac�  tites and forms the structure of coral reefs. Calcite is the most important  mineral in limestones and marbles used in the building, steel, chemical,  and glass industries. Transparent crystals are called Iceland spar.</p><p>calcium Chemical element, one of the alkaline earth metals, chemical sym�  bol Ca, atomic number 20. The most abundant metallic element in the  human body, it is an essential part of bones and teeth and has many physi�  ological functions (see calcium deficiency; tooth). It is the fifth most abun�  dant element in Earth�s crust but does not occur naturally in the free state.  In its compounds calcium has valence 2. It occurs in limestone, chalk, marble,  dolomite, eggshells, pearls, coral, and many marine shells as calcium car�  bonate, or calcite; in apatite as calcium phosphate; in gypsum as calcium sul�  fate; and in many other minerals. It is used as an alloying agent and in other  metallurgical applications; its alloy with lead is used in cable sheathing and  grids for batteries. Calcite is used as a lime source, a filler, a neutralizer, and  an extender; in pure form it is used in baking powder and as an antacid and  calcium supplement. Calcium oxide (lime) and its product after water addi�  tion, calcium hydroxide (slaked lime), are important industrially. Other sig�  nificant compounds are calcium chloride (a drying agent), calcium  hypochlorite (a bleach), calcium sulfate (gypsum and plaster of Paris), and  calcium phosphate (a plant food and stabilizer for plastics).</p><p>calcium deficiency Inadequate supply or metabolism of calcium, the  main structural element of bones and teeth. Its metabolism is regulated  by vitamin D, phosphorus, and hormones (see parathyroid gland). Calcium  in the blood has roles in muscle contraction, nerve-impulse transmission,  blood clotting, milk production, hormone secretion, and enzyme function,  for which calcium is pulled from the bones if deficiency develops. Chronic  deficiency may be a factor in the development of osteoporosis or osteo�  malacia (softening of bone) and may contribute to hypertension and colon  cancer. Severe calcium deficiency (hypocalcemia), usually the result of a  metabolic problem rather than a dietary deficiency, causes numbness, tin�  gling, and painful muscle aches and spasms.</p><p>calcium oxide See lime</p><p>calculator Machine for performing arithmetic operations and certain  mathematical functions automatically. Blaise Pascal devised a digital arith�  metic machine in 1642. By the late 19th century, such machines had  become smaller and easier to use, and desktop machines appeared in the  early 20th century. Electronic data-processing systems in the mid-1950s  led to the obsolescence of mechanical calculators.

While working as a bank clerk, he began  drawing for periodicals such as London Society, and, after he moved to  London, Punch and Graphic. He developed a gently satirical style and  achieved success with illustrations for Washington Irving�s books The  Sketch Book (1875) and Bracebridge Hall (1876). Caldecott is best known  as an illustrator of children�s books, including William Cowper�s John  Gilpin (1878) and Oliver Goldsmith�s Elegy on a Mad Dog (1879). Always  frail in health, he died at age 39 in Florida, where he had gone to improve  his condition.

July 22, 1898, Lawnton,  Pa., U.S.�d. Nov. 11, 1976, New  York, N.Y.) U.S. sculptor. He was the  son and grandson of sculptors, and  his mother was a painter. He studied  mechanical engineering, and in 1923  attended the Art Students League,  where he was influenced by artists of  the Ash Can school. In 1924 he con�  tributed illustrations to the National  Police Gazette. In 1926 he moved to  Paris and began making toylike ani�  mals and circus figures of wood and  wire; from these he developed his  famous miniature circus. In the  1930s he became well known in  Paris and the U.S. for his wire sculp�  tures, as well as for portraits,  continuous-line drawings, and  abstract, motor-driven constructions.</p><p>He is best known as the inventor of  the mobile, a forerunner of kinetic  sculpture. He also constructed nonmovable sculptural works known as sta�  biles. Although Calder�s early mobiles and stabiles were relatively small,  he increasingly moved toward monumentality in his later works. His art  was recognized with many large-scale exhibitions.</p><p>caldera \kal-'der-9\ Large, bowl-shaped volcanic depression that forms  when the top of a volcanic cone collapses into the space left after magma  is ejected during a violent volcanic eruption.

His secular plays included The Surgeon of His Honour  (1635), Life Is a Dream (1638), and his masterpiece. The Daughter of the  Air (1653). His many plays on religious themes include The Constant  Prince (1629) and The Wonder-Working Magician (1637). He also cre�  ated 76 one-act religious dramas, notably The Great Theatre of the World  (c. 1635) and The Faithful Shepherd (1678). Considered the successor to  Lope de Vega as the greatest playwright of the Spanish Golden Age, he was  noted for his well-constructed plots and his preoccupation with the van�  ity of human existence.</p><p>Caldwell, Erskine (b.

Fame arrived with Tobacco Road (1932), a controversial novel whose title  became a byword for rural squalor; adapted as a play, it ran more than  seven years on Broadway. God�s Little Acre (1933), also a best-seller,  featured a cast of hopelessly poor degenerates. Like his other novels and  stories about the rural Southern poor, they mix violence and sex in gro�  tesque tragicomedy.

Remnants also exist in eastern Greenland.</p><p>calendar System for dividing time over extended periods, such as days,  months, or years, and arranging these divisions in a definite order. A cal�  endar is essential for the study of chronology, which reckons time by  regular divisions, or periods, and uses these to date events. It is also vital  for any civilization that needs to measure periods for agricultural, busi�  ness, domestic, or other reasons. The lunation, or period in which the  moon completes a cycle of its phases (29Vi days), is the basis for the  month; most ancient calendars were collections of months. Days and sea�  sons, which are a solar phenomena, do not have periods that evenly divide,  so ancient calendars employed various means, such as the periodic inser�  tion of an intercalary month, to reconcile the months with the seasons.  The Gregorian calendar used almost universally today is a modification  of the Julian calendar adopted by Julius Caesar, which used a 36514-day  year with 12 months that came to have the number of days we know today.

In order to bring the calendar  in line with the annual solar cycle, a 13th month of 30 days is added in  the 3rd, 6th, 8th, 11th, 14th, 17th, and 19th years of a 19-year cycle.  Therefore, a leap year may have from 383 to 385 days.

The months are alternately  30 and 29 days long except for the 12th, Dhu al-Hijjah, the length of which  is varied in a 30-year cycle intended to keep the calendar in step with the  true phases of the moon. In 11 years of this cycle, Dhu al-Hijjah has 30  days, and in the other 19 years it has 29. Thus the year has either 354 or  355 days.

As a leader of the War  Hawks, he introduced the declaration  of war against Britain in June 1812  (see War of 1812). From 1817 to  1825 he served as U.S. secretary of  war. He was elected vice president in  1824 (under John Quincy Adams) and  again in 1828 (under Andrew Jack-  son). In the 1830s he became an  extreme advocate of strict construc�  tion of the U.S. Constitution, a  champion of states' rights, a defender  of slavery, and a supporter of nullifi�  cation. In 1832 he resigned the vice  presidency and was elected to the  U.S. Senate, where he served until  1850; he was briefly secretary of state in 1844-45. His exuberant defense  of slavery as a �positive good� aroused strong anti-Southern feeling in  the free states.</p><p>Cali Vka-le\ City (pop., 1999 est.: 2,077,386), western Colombia.

Its  capital is Sacramento. Within 85 mi (137 km) of each other lie Mount  Whitney and Death Valley, the highest and lowest points in the 48 con�  tiguous states. It was inhabited originally by American Indians. The first  European coastal expansion took place in 1542-43 when Juan Cabrillo  established a Spanish claim to the area. The first mission was established  by Junipero Serra at San Diego in 1769. The region remained under Span�  ish and, after the 1820s, Mexican control until it was taken by U.S. forces  in the Mexican War and ceded to the U.S. by the Treaty of Guadalupe  Hidalgo in 1848. Though settlement had begun by the U.S. in 1841, it was  greatly accelerated by the 1848 gold rush. California was admitted to the  Union in 1850 as a nonslavery state under the Compromise of 1850. Its  already expanding population grew immensely in the 20th century. It has  the largest economy of any U.S. state.

The Los Angeles branch (UCLA),  founded in 1919, includes schools of law, medicine, and engineering. The  Santa Barbara campus, originally founded as a teachers college, joined  the university system in 1944. The Davis and Riverside campuses grew  out of agricultural institutes and were added in 1959. To answer a grow�  ing need for broad-based education and research, the university opened  campuses at Santa Cruz and Irvine in 1965 and added the Merced cam�  pus in 2005.

Controversy over the selection of the fourth  caliph, c Au, eventually split Islam into the Sunnite and ShYite branches.  'All�s rival, Mu'awiyah I, established the Umayyad dynasty of caliphs, which  produced 14 caliphs (661-750). The 'Abbasid dynasty (750-1258), the most  widely observed caliphate, associated with 38 caliphs, moved the capital  from Damascus to Baghdad. The Mongol conquest of Baghdad in 1258  effectively ended the dynasty. Other Muslim leaders created caliphates  with limited success. The Fattmid dynasty proclaimed a new caliphate in  920; c Abd al-Rahman III announced one in opposition to both the 'Abbasids  and the Fatimids in 928. A scion of the 'Abbasid line was set up by the  MamlGk dynasty as a sort of puppet caliph after 1258. This caliphate exer�  cised no power whatsoever, and, from 1517 until it was abolished by the  Republic of Turkey in 1924, it resided in Istanbul under the control of the  Ottoman Empire. Modern Muslim militants consider the abolition of the  caliphate a catastrophic event, and its return has been a central pillar of  their political program.</p><p>calisthenics Systematic rhythmic bodily exercises (e.g., jumping jacks,  push-ups), usually performed without apparatus.

He served in Labour governments as chancellor of the Exchequer  (1964-67), home secretary (1967-70), and foreign secretary (1974-76)  before becoming prime minister (1976-79). A moderate within his party,  he tried to stem the vociferous demands of the trade unions. After a series  of paralyzing labour strikes in 1978-79 (the �Winter of Discontent�), his  government was brought down by a parliamentary vote of no confidence.  He was created a life peer in the House of Lords in 1987.</p><p>Callaghan \'ka-b-,han\, Morley (Edward) (b. Sept. 22, 1903, Tor�  onto, Ont., Can.�d. Aug. 25, 1990, Toronto) Canadian novelist and short-  story writer. Callaghan received a law degree in 1928 but never practiced.  He won acclaim for the short-story collection A Native Argosy (1929).  His first novel, Strange Fugitive (1928), describes the destruction of a  social misfit, a type that recurs in his fiction. Subsequent novels, includ�  ing They Shall Inherit the Earth (1935) and The Loved and the Lost (1951,  Governor General�s Award), emphasize Christian love as an answer to  social injustice. That Summer in Paris (1963) describes Callaghan�s  friendship with F. Scon Fitzgerald and Ernest Hemingway. Later works  include A Fine and Private Place (1975) and A Time for Judas (1983).</p><p>Callahan, Harry (Morey) (b. Oct. 22,1912, Detroit, Mich., U.S.�d.  March 15, 1999, Atlanta, Ga.) U.S. photographer. He had no formal train�  ing in photography and first developed an interest in it in 1938. In 1941  Ansel Adams�s photographs inspired him to develop his own style. His  subjects included landscapes, cityscapes, and unconventional portraits of  his wife and daughter. He was best known as a teacher; he was head of  the photography department at the Chicago Institute of Design (1949-61)  and developed the photography department at the Rhode Island School of  Design (1961-76). In 1980 two collections of his works were published,  Water�s Edge and Harry Callahan: Color, 1945-1980.</p><p>Callao \ka-'ya-o\ City (pop., 1996 est.: 407,904), chief seaport, Peru.

She  gained an international reputation for her performance in La Gioconda at  the 1947 Verona Festival. She continued to sing heavy dramatic roles,  including Giacomo Puccini�s Turandot and Richard Wagner�s Kundry, until  the conductor Tullio Serafin (1878-1968) convinced her to shift to the bel  canto repertoire, for which she became famous. Her signature role was  Vincenzo Bellini�s Norma. Though her voice was imperfect, her extraordi�  nary range, dramatic stage presence, and mastery of difficult roles made  her the most famous opera star of her day. Her fiery temperament and her  flamboyant and demanding personality made her an international celeb�  rity; she was the consummate diva.</p><p>calligraphy \ko-'lig-r3-fe\ Art of beautiful, stylized, or elegant hand�  writing or lettering with pen or brush and ink. It involves the correct for�  mation of characters, the ordering of the various parts, and the harmony  of proportions. In the Islamic and Chinese cultures, calligraphy is as  highly revered as painting. In Europe in the 14th-16th century, two scripts  developed that influenced all subsequent handwriting and printing: the  roman and italic styles. With the invention of modern printing (1450),  calligraphy became increasingly bold and ornamental.</p><p>Callimachus (fl. late 5th century bc) Greek sculptor.

In 1612, at the court of the Medici family in Flo�  rence, he was employed to make pictorial records of pageants and feasts.  He had a genius for caricature and the grotesque; his series of etchings  The Miseries of War (1633), documenting the atrocities of the Thirty  Years� War, was used as a source by Francisco de Goya. His output was  prodigious; more than 1,400 etchings and 2,000 drawings survive. One  of the greatest of all etchers, he was also one of the first major artists to  practice the graphic arts exclusively.</p><p>Calloway, Cab orig. Cabell Calloway III (b.

He fronted his first group in 1928; it became the house band  at Harlem�s Cotton Club in 1931. An accomplished scat singer who com�  bined audacious showmanship with prodigious vocal range and imagina�  tion, he became most identified with his hit �Minnie the Moocher� (1931).

After the Revolution began, he devoted himself to the  cause of counterrevolution from his exile in England.</p><p>calorie Unit of energy or heat. Various precise definitions are used for  different purposes (physical chemistry measurements, engineering steam  tables, and thermochemistry), but in all cases the calorie is about 4.2  joules, the amount of heat needed to raise the temperature of 1 g of water  by 1 �C (1.8 �F) at normal atmospheric pressure. The calorie used by  dietitians and food scientists and found on food labels is actually the kilo�  calorie (also called Calorie and abbreviated kcal or Cal), or 1,000 calo�  ries.

In 1633 he was sent from  England to establish a settlement at St. Mary�s. He gradually allowed  limited legislative initiative in the colony�s assembly. He lost a land con�  flict with William Claiborne and was forced to leave Maryland (1644�46);  aided by colonists, including Margaret Brent, he returned to reinstate his  proprietorial rule.</p><p>Calvin, John French Jean Cauvin \ko-'va n \ (b. July 10, 1509,  Noyon, Picardy, France�d. May 27, 1564, Geneva, Switz.) French Prot�  estant theologian and major figure of the Reformation. He studied religion  at the University of Paris and law in Orleans and Bourges. When he  returned to Paris in 1531 he studied the Bible and became part of a move�  ment that emphasized salvation by grace rather than by works. Govern�  ment intolerance prompted him to move to Basel, Switz., where he wrote  the first edition of Institutes of the Christian Religion (1536). Gaining a  reputation among Protestant leaders, he went to Geneva to help establish  Protestantism in that city. He was expelled by city fathers in 1538 but  returned in 1541, when the town council instituted the church order out�  lined in his Ecclesiastical Ordinances, including enforcement of sexual  morality and abolition of Catholic �superstition.� He approved the arrest  and conviction for heresy of Michael Servetus. By 1555 Calvin had suc�  ceeded in establishing a theocracy in Geneva, where he served as pastor  and head of the Genevan Academy and wrote the sermons, biblical com�  mentaries, and letters that form the basis of Calvinism.</p><p>Calvin, Melvin (b. April 8, 1911, St. Paul, Minn., U.S.�d. Jan. 8,  1997, Berkeley, Calif.) U.S. biochemist. He received his Ph.D. from the  University of Minnesota. He developed a system of using the radioactive  isotope carbon-14 as a tracer element in his studies of the green alga chlo-  rella. By halting the plant�s metabolism at various stages and measuring  tiny amounts of radioactive compounds present, Calvin was able to iden�  tify most of the reactions involved in the intermediate steps of photosyn�  thesis, for which he was awarded a 1961 Nobel Prize. His research also  included work in radiation chemistry and the processes leading to the ori�  gin of life.</p><p>Calvinism In Protestantism, the theology developed and advanced by  John Calvin. It was further developed by his followers and became the  foundation of the Reformed church and Presbyterianism. As shaped by  Calvin�s successor at Geneva, Theodore Beza (1519-1605), Calvinism  emphasizes the doctrine of predestination, holding that God extends grace  and grants salvation only to the chosen, or elect. It stresses the literal truth  of the Bible, and it views the church as a Christian community in which  Christ is head and all members are equal under him. It therefore rejects  the episcopal form of church government in favor of an organization in  which church officers are elected. Calvinism was the basis of theocracies  in Geneva and Puritan New England (see Puritanism), and it strongly influ�  enced the Presbyterian church in Scotland.</p><p>Calvino \kal-'ve-no\, Italo (b. Oct. 15, 1923, Santiago de las Vegas,  Cuba�d. Sept. 19, 1985, Siena, Italy) Cuban-born Italian writer. After  early works inspired by his involvement with the Italian Resistance in  World War II, he turned decisively to fantasy and allegory in the 1950s.  Cosmicomics (1965) is a collection of whimsical narratives about the cre�  ation and evolution of the universe. The novels Invisible Cities (1972),  The Castle of Crossed Destinies (1973), and If on a Winter�s Night a  Traveler (1979) use playfully innovative structures and shifting view�</p><p>points. The Uses of Literature (1980) is a collection of essays he wrote  for a left-wing journal he edited from 1959 to 1966.</p><p>calypso \k3-'lip-so\ Musical style best known as a type of folk song.  Calypso originated in Trinidad but is common throughout the Caribbean.  The calypso tradition dates to the early 19th century. The subject of a  calypso text, usually witty and satiric, is an event of political or social  import. The lyric often incorporates Spanish, Creole, and African phrases,  employing newly invented expressions such as bobol (graft) and pakoti  (unfaithfulness). The exaggeration of local speech patterns is matched by  an offbeat rhythm. Favourite accompanying instruments are the shak-shak  (maraca), cuatro (a string instrument), and tamboo-bamboo (bamboo poles  of various lengths struck on the ground). Shaped and tuned oil drums,  played together in orchestras called steel bands, have also been popular.</p><p>cam Machine component that either rotates or reciprocates (moves back  and forth) to create a prescribed motion in a contacting element (the fol�  lower). Since the shape of the contacting surface of the cam is determined  by the prescribed motion and the profile of the follower, cams take vari�  ous forms. Cam-follower mechanisms are particularly useful when a  simple motion of one part of a machine is to be converted to a more com�  plicated prescribed motion of another part, one that must be accurately  timed with respect to the simple motion and may include periods of rest  (dwells). Cams are essential elements in automatic machine tools, printing  machines, sewing machines, and textile machinery.</p><p>Cam Ranh Vkam-'ranV Bay Vietnamese Vinh Cam Ranh Inlet of  the South China Sea, south-central Vietnam.

She made her Paris Opera debut in 1726 and went on  to dance in 78 ballets and operas before her retirement in 1751. Admired  for her speed and agility, she executed jumping steps previously per�  formed only by male dancers, shortening her skirts and removing the heels  from her slippers to enable her do so. Her name was adopted in 1930 by  a British ballet group, the Camargo Society.</p><p>Camargue \ka-'marg\ Marshy island in the delta of the Rhone River,  southern France.

In the early centuries ad  the area was under Hindu and, to a lesser  extent, Buddhist influence. The Khmer state  gradually spread in the early 8th century</p><p>and reached its height under Jayavarman II and his successors in the 9th-  12th centuries, when it ruled the Mekong valley and neighbouring states  and built Angkor. Buddhism was widely adopted in the 13th century.  From the 13th century the state was attacked by Annam and Tai (Siamese)  city-states and was subject largely to Tai and Vietnamese hegemony. It  became a French protectorate in 1863. It was occupied by the Japanese  in World War II and became independent in 1954. Its borders were the  scene of fighting in the Vietnam War from 1961, and in 1970 its north�  eastern and eastern areas were occupied by the North Vietnamese and  penetrated by U.S. and South Vietnamese forces. A bombing campaign in  Cambodia by U.S. warplanes alienated much of the population, enabling  the communist Khmer Rouge under Pol Pot to seize power in 1975. Their  regime of terror resulted in the deaths of at least 1.5 million Cambodi�  ans. Vietnam invaded in 1978 and drove the Khmer Rouge into the west�  ern hinterlands, but Cambodian infighting continued. A peace accord was  reached by most Cambodian factions under UN auspices in 1991. Elec�  tions were held in 1993, and Norodom Sihanouk was restored to the mon�  archy. A civilian government slowly emerged under UN tutelage until  1997, when a coup by Hun Sen consolidated his position as prime min�  ister. Hun Sen�s party won legislative elections in 1998; also that year,  Cambodia became part of ASEAN.</p><p>Cambodian See Khmer</p><p>Cambodian language See Khmer language</p><p>Cambon \ka n -'bo n \, (Pierre-) Paul (b.

League of (1508-10) Alliance of Pope Julius II,  Emperor Maximilian I, King Louis XII, and King Ferdinand V, formed in  1508. Ostensibly directed against the Turks, its actual aim was to attack  the Republic of Venice and divide its possessions among the allies. The  allies were unable to act together because of their individual ambitions,  and the league collapsed in 1510, when the pope joined with Venice, while  Ferdinand became neutral.</p><p>Cambrai \kam-'bra\, Treaty of or Paix des Dames Vpe-da-'damX  (French: �Peace of the Ladies�) (August 3, 1529) Agreement ending one  phase of the wars between Francis I of France and Emperor Charles V,  temporarily confirming Spanish (Habsburg) control in Italy.

Its beginnings lie in an exo�  dus of scholars from the University of Oxford in 1209. Its first college  was built in 1284, and the university was officially recognized by the pope  in 1318. From 1511 Desiderius Erasmus did much to inculcate the new  learning of the Renaissance at Cambridge. In 1546 Henry VIII founded  Trinity College, which remains the largest of Cambridge�s 31 colleges.  From 1669 Isaac Newton taught mathematics, giving this field a unique  position there. In 1871 James Clerk Maxwell accepted the chair of experi�  mental physics, beginning a leadership in physics that would continue into  the next century. A host of world-renowned scholars in other fields have  also taught at Cambridge, including John Maynard Keynes in economics  and Stephen W. Hawking in applied mathematics and theoretical physics.  Many of the university�s buildings, including the famous King�s College  Chapel and two chapels designed by Christopher Wren, are rich in history  and tradition.

The  artists met weekly in the studio of Walter Sickert (1860-1942), the group�s  prime inspiration, in a working-class area of London. The Camden Town  artists utilized an Impressionist technique but were also open to the influ�  ence of Post-Impressionism. Their subject matter was derived from the  everyday life of an English industrial town. Despite a somewhat expres�  sive use of colour, their paintings remained representational and realistic,  reflecting an interpretation of a modem aesthetic different from the more  formally daring developments emerging in Paris at the same time. The  Camden Town Group was absorbed in 1913 by the London Group, a com�  bination of several smaller groups of contemporary English artists.</p><p>camel Either of two species of large, hump-backed ruminants of the  family Camelidae. Camels are used  as draft and saddle animals in desert  regions of Africa, Arabia, and Asia.</p><p>Adaptations to windblown deserts  include double rows of eyelashes,  the ability to close the nostrils, and  wide-spreading soft feet. They also  can tolerate dehydration and high  body temperatures. They are thus  able to go several days without  drinking water. Though docile when  properly trained, camels can be dan�  gerous. The Bactrian camel ( Came-  lus bactrianus) is about 7 ft (2 m) tall  at the top of the two humps; the Ara�  bian camel (C. dromedarius), or  dromedary, has one hump and is 7 ft  (2 m) high at the shoulder. When  food is available, camels store fat in their humps to be used later for sus�  tenance; water is produced as a by-product of fat metabolism. The feral  camels of Australia were introduced to that continent in the 1800s.</p><p>camel racing Sport of running camels at speed, with a rider astride,  over a predetermined course. The sport is generally limited to running the  dromedary�whose name is derived from the Greek verb dramein, �to  run��rather than the Bactrian camel. Camel racing on the Arabian Pen�  insula can be traced to at least the 7th century. Although traditionally  overshadowed by horse racing in that region, the racing of camels was  long a folk sport practiced at social gatherings and festivals. In the late  20th century it was organized into a formal sport, similar to Thorough�  bred horse racing. The sport is popular in India, Australia, parts of East  Africa, and especially the Arab countries of the Middle East. A race typi�  cally has 25 to 30 entries and covers distances ranging from 2.5 to 6 mi  (4 to 10 km).</p><p>camellia Nko-'mel-yoV Any of the East Asian evergreen shrubs and trees  that make up the genus Camellia in the tea family (Theaceae), most  notable for three ornamental flowering species and for C. sinensis (some�  times called Thea sinensis ), the source of tea. The common camellia (C.  japonica ) is the best-known, particularly for its double (many-petaled)  cultivated varieties. The tea plant (C. sinensis ), reaching 30 ft (9 m) in  the wild but in cultivation kept to a low, mounded shrub, bears fragrant  white, yellow-centred flowers.</p><p>Camelot In Arthurian legend, the seat of King Arthur�s court. It has been  variously identified with Caerleon in Wales, Queen Camel in Somerset,  Camelford in Cornwall, Winchester in Hampshire, and Cadbury Castle in  Somerset. Camelot has come to symbolize a short-lived golden era under  a beloved leader.</p><p>cameo Hard or precious stone, glass, ceramic, or shell carved in relief  above the surface. It is the opposite  of intaglio. Surviving cameos date  from the early Sumerian period (c.</p><p>3100 bc) to the decline of Roman  civilization, and from the Renais�  sance to the Neoclassical period of  the 18th century. They were carved  with mythological scenes and por�  traits, and many commemorated spe�  cific persons. In the 18th�19th  century, cameos adorned diadems,  belts, brooches, and bracelets.</p><p>cameo glass Glassware deco�  rated with figures and forms in  coloured glass carved in relief  against a glass background of a con�  trasting colour. It is produced by  blowing two layers of glass together.</p><p>When the glass has cooled, an out�  line of the design is drawn on the surface and covered with wax. The  glass is then etched down to the inner layer, leaving the design outline in  relief. Fine cameo glass was produced by the Romans in the 1st century  ad. The art was revived by John Northwood in England and Emile Galle  in France in the late 19th century.</p><p>camera Device for recording an image of an object on a light-sensitive  surface (see photography). It is essentially a light-tight box with an open�  ing (aperture) to admit light focused onto a sensitized film or plate. All  cameras have included five crucial components: (1) the camera box, which  holds and protects the sensitive film from all light except that entering  through the lens; (2) film, on which the image is recorded; (3) the light  control, consisting of an aperture or diaphragm and a shutter, both often  adjustable; (4) the lens, which focuses the light rays from the subject onto  the film, creating the image; and (5) the viewing system, which may be  separate from the lens system (usually above it) or may operate through  it by means of a mirror. The camera was inspired by the camera  obscura�a dark enclosure with an aperture (usually provided with a lens)  through which light enters to form an image of outside objects on the  opposite surface�and was developed by Nicephore Niepce and L.-J.-M.  Daguerre in the early 19th century. See also digital camera.</p><p>Camerarius \,kam-3-'rar-e-3s\, Rudolph (Jacob) German  Rudolph Camerer (b. Feb. 17, 1665, Tubingen, Ger.�d.

One of the first to perform experiments  in heredity, he demonstrated sexuality in plants by identifying and defin�  ing the male and female reproductive parts of the plant and by describ�  ing their function in fertilization, showing that pollen is required for the  process.</p><p>Cameron, Julia Margaret (b. June 11, 1815, Calcutta, India�d.  Jan. 26, 1879, Kalutara, Ceylon) British portrait photographer. In 1864,  after receiving a camera as a gift, she set up a studio and darkroom and  began taking portraits. Her sitters were friends such as Alfred Tennyson,  Henry Wadsworth Longfellow, and Charles Darwin. Her sensitive portraits  of women, such as that of Ellen Terry, are especially noteworthy. Like  many Victorian photographers, she made allegorical photographs in imi�  tation of the Pre-Raphaelite paintings of the day. Her technical ability was  criticized, but she was more interested in spiritual depth than in technical  perfection; her portraits are considered exceptionally fine.</p><p>Bactrian camel (Camelus bactrianus)</p><p>�GEORGE HOLTON-THE NATIONAL AUDUBON SOCIETY  COLLECTION/PHOTO RESEARCHERS</p><p>a</p><p>"The Rape of Europa," cameo in gold  and enamel frame, 16th�17th century;  in the Kunsthistorisches Museum,  Vienna</p><p>COURTESY OF THE KUNSTHISTORISCHES MUSEUM, VIENNA</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Cameron &#x25BA; Campania i 319</p><p>Cameron, Simon (b.

Area: 183,569 sq mi (475,442 sq km). Population (2005 est.): 16,988,000.  Capital: Yaounde. The country has numerous ethnic groups, including the</p><p>Fang (one-fifth of the population), Bam-  ileke (one-fifth), Duala, and Fulani. Pyg�  mies (locally known as Baguielli and  Babinga) live in the southern forests. Lan�  guages: French, English (both official),  Fula, Bamileke, Duala. Religions: Christianity (mostly Roman Catholic;  also Protestant), traditional beliefs, Islam (mainly in the north). Currency:  CFA franc. Cameroon has four geographic regions. The southern area  consists of coastal plains and a densely forested plateau. The central  region rises progressively to the north and includes the Adamawa Plateau.  In the north a savanna plain slopes downward toward the Lake Chad basin.  To the west and north along the Nigerian border the relief is mountain�  ous and includes Mount Cameroon. Of the main rivers, the Sanaga drains  into the Atlantic Ocean, and the Benue flows westward into the Niger River  basin in Nigeria. Cameroon has a developing market economy based  largely on agriculture but with a growing services sector. It is a republic  with one legislative house; its chief of state is the president and its head  of government the prime minister. Long inhabited before European colo�  nization, Cameroon was peopled by Bantu-language speakers coming  from equatorial Africa to settle in the south. They were followed by Mus�  lim Fulani from the Niger River basin, who settled in the north. Portu�  guese explorers visited in the late 15th century, and the Dutch were also  active there. In 1884 the Germans took control and extended their pro�  tectorate over Cameroon. In World War I joint French-British action  forced the Germans to retreat, and after the war the region was divided  into French and British administrative zones. After World War II the two  areas became UN trusteeships. In 1960 the French trust territory became  an independent republic. In 1961 the southern part of the British trust ter�  ritory voted for union with the new Republic of Cameroon, and the north�  ern part voted for union with Nigeria. The independent country has faced  chronic economic problems, which have produced unrest in the country.</p><p>Cameroon, Mount Volcanic massif, Cameroon. Rising to 13,435 ft  (4,095 m), it is the highest peak in West Africa.

Though a patrician, he adopted reforms  beneficial to the army and the plebeians (367).</p><p>Camisards Vkam-o-.zardzV Protestant militants in southern France who  opposed Louis XIV�s persecution of Protestantism. The armed insurrection,  which began in 1702, came in response to Louis�s revocation of the Edict  of Nantes, ending religious toleration. The well-organized Camisards, so  named for their white shirts (in French dialect, camisa ), fought success�  fully and even held royal armies in check. In response, the government  burned hundreds of villages and massacred their populations. By 1705,  with many of the Camisard leaders captured and executed, the revolt had  lost its force.</p><p>Camoes \k3-'m6i n sh\, Luis (Vaz) de (b. c. 1524/25, Lisbon�d. June  10, 1580, Lisbon) Portuguese poet. A member of the impoverished aris�  tocracy, he may have spent about 17 years in India. His masterpiece, the  epic The Lusiads (1572), extols glorious deeds in Portuguese history as  it recounts Vasco da Gama�s discovery of the sea route to India. His  numerous lyric pieces (together with many apocryphal poems) appeared  posthumously in editions of the poetry collection Rimas (from 1595). He  also wrote dramatic works, including Filodemo (1587), in which he devel�  oped the auto , a kind of morality play, and the comedy The Two Amphi-  tryons (1587). He had an unparalleled impact on Portuguese and Brazilian  literature and is regarded as Portugal�s national poet.</p><p>camouflage Vka-mo-.flazhX Art and practice of concealment and visual  deception in war. Its goal is to prevent enemy observation of installations,  personnel, equipment, and activities. Camouflage came into wide use in  World War I in response to air warfare. Aerial reconnaissance (and later  aerial bombardment) required concealment of troops and equipment. By  World War II, long-range bombing threatened warring countries in their  entirety, and almost everything of military significance was hidden to  some degree, using mottled, dull-coloured paint patterns (green, gray, or  brown), cloth garnishing, netting, and natural foliage. Dummies and  decoys, including fake vehicles and airfields, tricked enemy planes into  bombing harmless targets. It remained an important technique after World  War II, used with notable success by communist guerrilla units in the  Vietnam War.</p><p>Camp David Rural retreat of U.S. presidents, northern Maryland. The  scenic mountainous area (200 acres, or 81 hectares) was established as  �Shangri-La� in 1942 by Pres. Franklin Roosevelt and made an official  presidential retreat by Harry Truman in 1945. In 1953 Dwight D. Eisen�  hower renamed it Camp David for his grandson. It has been the scene of  a number of high-level presidential conferences with foreign heads of  state.

This  treaty, normalizing relations, was signed in 1979 and led to the return of  the Sinai Peninsula, occupied by Israel in the Six-Day War (1967), to Egypt.  The other agreement created a framework for a broader peace in the region  that included a plan for Palestinian self-rule in the West Bank and Gaza  Strip. The latter provisions were not implemented.

The earliest campaniles (7th-10th century) were  plain round towers with a few small arched openings near the top; the  Leaning Tower of Pisa is an elaborate version of this type. The Venetian  form of campanile consisted of a tall, square, slim shaft, frequently  tapered, with a belfry at the top, above which rose the spire, sometimes  square as in the famous campanile of St. Mark's Basilica (1 Oth� 12th cen�  tury, belfry story 1510). After falling out of favor during the Renaissance,  the Venetian type was revived in the 19th century, often in connection  with factories, housing, or collegiate buildings.</p><p>campanula See bellflower</p><p>Campbell, John Archibald (b.

After being admit�  ted to the bar at age 18, he moved to Alabama, where he gained a large  private practice and served in the state legislature. Appointed to the  Supreme Court of the United States in 1853, he became known as a strict  constructionist; his tenure was notable for his concurrence in the Dred  Scott decision. Although he opposed secession as imprudent, he resigned  from the Supreme Court in 1861 and cast his lot with the South in the  American Civil War, serving as assistant secretary of war for the Con�  federacy. After the South�s surrender he was imprisoned for four months  on false charges. Upon his release he moved to New Orleans, where he  established a law practice.</p><p>Campbell, Joseph (b.

He explored the common functions of myths in human cultures,  examining mythic archetypes in folklore and literature from around the  world. His views, strongly influenced by Carl Gustav Jung, were popu�  larized through a public-television series in the 1980s. His books include  The Hero with a Thousand Faces (1949) and The Masks of God (4 vol.,</p><p>1959-67).</p><p>Campbell, Kim orig. Avril Phaedra Campbell (b. March 10,  1947, Port Alberni, B.C., Can.)

She originated the role  of Eliza Doolittle in George Bernard Shaw�s Pygmalion (1914), and she  and Shaw conducted a famous correspondence for many years. She also  achieved great success in Maurice Maeterlinck�s Pelleas and Melisande,  Henrik Ibsen�s Ghosts, and Sophocles' Electra. She made her film debut in  Riptide (1933) at age 68 and later appeared in several more films.</p><p>Campbell family Vkam-boL or Campbells of Argyll \ar-'gil\  Scottish noble family. The Campbells of Lochow gained prominence in  the later Middle Ages. In 1457 Colin Campbell, Baron Campbell (died  1493), was created 1st earl of Argyll. Archibald (died 1558), 4th earl, was  a leading Protestant. Archibald (15327-1573), 5th earl, was also a Prot�  estant but supported the Catholic Mary, Queen of Scots. Archibald  (16077-1661), 8th earl, was the leader of Scotland�s anti-Royalist party  in the English Civil Wars. His son Archibald (1629-1685), 9th earl, was a  Protestant leader executed for his opposition to the Roman Catholic king  James II. Archibald (16517-1703), 10th earl, regained the family estates  and was created 1st duke of Argyll; he organized the massacre of the  Macdonalds of Glencoe. John Campbell (1678-1743), 2nd duke, sup�  ported union with England and was commander of the British forces in  the Jacobite rebellion of 1715. Archibald (1682-1761), 3rd duke, was a</p><p>prominent politician during the early Hanoverian period in Britain.

Bounded by the  Yucatan Peninsula, the Isthmus of Tehuantepec, and the southern part of  the state of Veracruz, it covers about 6,000 sq mi (15,500 sq km). Major  offshore oil fields were developed in the bay in the 1970s, and it became  Mexico�s principal oil-producing region. In 1979 an accident at an oil well  there released some 3 million barrels of crude oil into the gulf; the gov�  ernment spent more than $100 million to bring the spill under control.</p><p>camphor Organic compound of the isoprenoid family.

He is identified with the Master of Fle-  malle on stylistic grounds. Documents show that Campin was a master  painter in Tournai in 1406; two students are listed as entering his studio  in 1427: Rogier van der Weyden and Jacques Daret. Campin�s principal  surviving works are two large panels of an altarpiece once believed to  have come from a nonexistent Abbey of Flemalle. The famous Merode  Altarpiece, a triptych of the Annunciation formerly regarded as his mas�  terpiece, is now thought to be by a member of his workshop or circle.  Characterized by a naturalistic conception of form and a poetic represen�  tation of the objects of daily life, Campin�s work marks the break with  the prevailing International Gothic style and prefigures the achievements  of the painters of the Northern Renaissance. Despite much uncertainty  about his life and work, he was one of the most important and influential  Flemish artists of the 15th century.</p><p>camping Recreational activity in which participants live outdoors, often  in the wilderness, usually using tents, trailers, or motor homes, but some�  times only a sleeping bag, for shelter. Modem camping originated near  the end of the 19th century in the U.S. as a rough, back-to-nature pastime  for hardy lovers of nature. Canoes were the original vehicle; bicycle  camping soon followed. Camping was a major part of the programs of the  Boy Scouts and Girl Guides (see scouting). It gained greatly in popular�  ity after World War II. As the number of campgrounds with greater ameni�  ties grew, it became the standard holiday for many ordinary families.  Recent decades have seen its continued growth, to the point of placing a  serious strain on the resources of state and federal outdoor-recreation  areas.

Jan. 4,  1960, near Sens, France) Algerian-French novelist, essayist, and play�  wright. Born into a working-class family, Camus graduated from the uni�  versity in Algiers and then worked with a theatrical company, becoming  associated with leftist causes. He spent the war years in Paris, and the  French Resistance brought him into the circle of Jean-Paul Sartre and exis�  tentialism. He became a leading literary figure with his enigmatic first  novel, The Stranger (1942), a study of 20th-century alienation, and the  philosophical essay �The Myth of Sisyphus� (1942), an analysis of con�  temporary nihilism and the concept of the absurd. The Plague (1947), his  allegorical second novel, and �The Rebel� (1951), another long essay,  developed related issues. Other major works include the short-story col�  lection Exile and the Kingdom (1957) and the posthumous autobiographi�  cal novel The First Man (1994). His plays include Le Malentendu (1944)  and Caligula (1944). Camus won the Nobel Prize for Literature in 1957.  He died in a car accident.</p><p>Canaan Vka-naM Ancient name for an area of shifting boundaries but  centred on Palestine. Coastal Canaanite civilization dates to the Paleolithic  Period; towns developed in Neolithic times (c. 7000-4000 bc). The name  appears in writings from the 15th century bc. Invaded by the Hebrews (c.  1200 bc), who settled in southern areas, it was later invaded by the Phi�  listines. In the 10th century bc the Israelites, under King David, broke Phi�  listine power, and Canaan became thereafter the Land of Israel, the  �Promised Land� of the biblical book of Exodus.</p><p>Canada Country, North America.

A large interior basin centred on Hudson Bay and  covering nearly four-fifths of the country is composed of the Canadian</p><p>Shield, the interior plains, and the Great Lakes-St. Lawrence lowlands.  Rimming the basin are highland regions, including the Arctic Archipelago.  Mountain ranges include the Rocky, Coast, and Laurentian mountains.  Canada�s highest peak is Mount Logan (19,551 ft [5,959 m]) in Yukon Ter�  ritory. Five of Canada�s rivers�the St. Lawrence, Mackenzie, Yukon,  Fraser, and Nelson �rank among the world�s 40 longest. In addition to  Lakes Superior and Huron, both shared with the U.S., Canada�s Great Bear  and Great Save lakes are among the world�s 11 largest lakes in area. The  country also includes several major islands, including Baffin, Ellesmere,  Victoria, Newfoundand, and Melville, and many small ones. Its border with  the U.S., the longest border in the world not patrolled by military forces,  extends 5,525 mi (8,890 km). With a developed market economy that is  export-directed and closely linked with that of the U.S., Canada is one of  the world�s most prosperous countries. It is a parliamentary state with two  legislative houses; its chief of state is the British monarch, whose repre�  sentative is Canada�s governor-general, and the head of government is the  prime minister. Originally inhabited by American Indians and Inuit,  Canada was visited c. ad 1000 by Scandinavian explorers, whose settle�  ment is confirmed by archaeological evidence from Newfoundland. Fish�  ing expeditions off Newfoundland by the English, French, Spanish, and  Portuguese began as early as 1500. The French claim to Canada was made  in 1534 when Jacques Cartier entered the Gulf of St. Lawrence. A small  settlement was made in Nova Scotia (Acadia) in 1604, and by 1608 Samuel  de Champain had reached Quebec. Fur trading was the impetus behind the  early colonizing efforts. In response to French activity, the English in 1670  formed the Hudson's Bay Company. The British-French rivalry for the inte�  rior of upper North America lasted almost a century. The first French loss  occurred in 1713 at the conclusion of Queen Anne's War (War of the Span�  ish Succession), when Nova Scotia and Newfoundland were ceded to the  British. The Seven Years' War (French and Indian War) resulted in France�s  expulsion from continental North America in 1763. After the American  Revolution Canada�s population was augmented by loyalists fleeing the  United States, and the increasing number arriving in Quebec led the Brit�  ish to divide the colony into Upper and Lower Canada in 1791. The British  reunited the two provinces in 1841. Canadian expansionism resulted in the  confederation movement of the mid-19th century, and in 1867 the Domin�  ion of Canada, comprising Nova Scotia, New Brunswick, Quebec, and  Ontario, came into existence. After confederation, Canada entered a  period of westward expansion. The prosperity that accompanied Canada  into the 20th century was marred by continuing conflict between the  English and French communities. Through the Statute of Westminster  (1931), Canada was recognized as an equal partner of Great Britain. With  the Canada Act of 1982, the British gave Canada total control over its con�  stitution and severed the remaining legal connections between the two  countries. French Canadian unrest continued to be a major concern, with  a movement growing for Quebec separatism in the late 20th century. Ref-  erendums for more political autonomy for Quebec were rejected in 1992  and 1995, but the issue remained unresolved. In 1999 Canada formed the  new territory of Nunavut.

Observed on July 1, it commemorates the formation of the Dominion of  Canada on July 1, 1867. With the 1982 passage of the Canada Act, its  name was officially changed to Canada Day. It is celebrated with parades,  fireworks, flag display, and the singing of the national anthem, �O  Canada.�</p><p>Canada East or Lower Canada Region of Canada now known as  Quebec. In 1791-1841 it was known as Lower Canada and in 1841-67 as  Canada East. Populated mainly by French settlers who wanted to preserve  their distinctive identity and cultural traditions, it was reluctant to join the  proposed confederation with Canada West. It finally agreed to confed�  eration in 1867, providing that it would remain a territorial and govern�  mental unit in which French Canadians would have an electoral majority.</p><p>Canada goose Brown-backed, light-breasted goose (Branta canaden�  sis) with a black head and neck and  white cheeks. Subspecies vary in  size, from the 4.4-lb (2-kg) cackling  goose to the 14.3-lb (6.5-kg) giant  Canada goose, which has a wing-  spread of up to 6.6 ft (2 m). Canada  geese breed across Canada and  Alaska and winter mainly in the  southern U.S. and Mexico; they have  been introduced into England and  other countries. They are an impor�  tant game bird. Their almost inces�  sant honking draws attention to their  V-formations during migration. In  recent years their population in  North America has increased, mak�  ing them pests in some inhabited  areas.</p><p>Canada West or Upper Canada Region of Canada now known as  Ontario. In 1791-1841 it was known as Upper Canada and in 1841-67  as Canada West. Settled primarily by English-speaking immigrants, it  sought confederation with Canada East in order to secure the unified gov�  ernment needed for effective administration and the construction of inter�  colonial railways. The unified Dominion of Canada was made official by  the British North America Act of 1867.</p><p>Canadian Alliance French Alliance Canadienne Former con�  servative Canadian political party. It was created in 2000 from the merger  of the Reform Party of Canada with other conservative groups in an effort  to mount a united challenge to the ruling Liberal Party of Canada. By 1997  the Reform Party, whose support had been concentrated in the western  Canadian provinces, held 60 seats in the Canadian House of Commons  and was the official opposition party. The new Canadian Alliance gained  66 seats in the 2000 election and became the official opposition, though  it was unable to make significant inroads in eastern Canada. In 2003 the  party merged with the Progressive Conservative Party to form the Conser�  vative Party of Canada. The party�s platform generally favoured a reduc�  tion in the size of government, lower taxes, and conservative positions on  social issues.</p><p>Canadian Broadcasting Corp.

It represents roughly 3 million unionized workers across  Canada.</p><p>Canadian National Railway Co. Corporation created by the  Canadian government in 1918 to operate a number of nationalized rail�  roads (including the old Grand Trunk lines. Intercolonial Railway,  National Transcontinental Railway, and Canadian Northern Railway) as  one of Canada�s two transcontinental railroad systems. Its passenger ser�  vices were taken over by VIA Rail Canada in 1978, and the company was  privatized in 1995. The Canadian National Railway stretches across  Canada from Nova Scotia to Vancouver.

It is the largest mass of exposed Precam-  brian rock on earth. The region as a whole is composed of ancient  crystalline rocks whose complex structure attests to a long history of uplift  and depression, mountain building, and erosion.</p><p>canal Artificial waterway built for transportation, irrigation, water sup�  ply, or drainage. The early Middle Eastern civilizations probably first built  canals to supply drinking and irrigation water. The most ambitious navi�  gation canal was a 200-mi (320-km) construction in what is now Iraq.  Roman canal systems for military transport extended throughout northern  Europe and Britain. The most significant canal innovation was the pound  lock, developed by the Dutch c. 1373. The closed chamber, or pound, of  a lock is flooded or drained of water so that a vessel within it is raised or  lowered in order to pass between bodies of water at different elevations.  Canals were extremely important before the coming of the railroad in the  mid-19th century. Among the significant waterways in the U.S. were the  Erie Canal, several canals linking the Great Lakes, and one connecting the  Great Lakes to the Mississippi River. Modern waterway engineering  enables larger vessels to travel faster by reducing delays at locks. See also  Grand Canal, Panama Canal, Suez Canal. See illustration on following  page.</p><p>Canal Zone or Panama Canal Zone Strip of territory, a historic  administrative entity in Panama over which the U.S. formerly exercised  jurisdictional rights (1903-79). The zone came into being in 1904 when  Panama granted the U.S., in return for annual payments, sole right to  operate and control the Panama Canal, including a strip of land 10 mi (16  km) wide along the canal extending from the Atlantic to the Pacific Ocean  and bisecting the Isthmus of Panama. The zone was abolished by treaty  in 1979, and civil control of the territory was returned to Panama. By the  same treaty a commission under joint U.S.-Panamanian ownership was  established to operate the canal until the year 2000, when Panama  assumed full control.</p><p>Canaletto \,ka-n 3 l-'e-to\ orig.

His pictures provide dramatic views of Venetian  architecture and demonstrate skill in rendering sunlight and shadow. In the  1730s he was kept busy meeting foreign visitors� demand for souvenir  views of Venice. When the War of the Austrian Succession made foreign  visitors scarce, he expanded his output to include imaginative views of  Roman ruins, and in 1746 he went to England to paint views of London  and the great English country houses. In 1763 he was elected to the Vene�  tian Academy. The most famous topographical painter of the 18th century,  he influenced succeeding generations of landscape artists. He is not to be  confused with his nephew Bernardo Bellotto, also known as Canaletto.</p><p>Canaris \ka-'na-ros\, Wilhelm (Franz) (b. Jan. 1, 1887, Aplerbeck,  Westphalia, Ger.�d.

Believing that the Nazi regime  would destroy traditional conservative values and that its foreign ambi�  tions were dangerous to Germany, he enlisted some of the anti-Hitler con�  spirators into the Abwehr and shielded their activities. After the abortive  July Plot against Hitler in 1944, Canaris was arrested and executed.</p><p>canary Popular cage bird (Serinus canaria', in the goldfinch family,  Carduelidae) that owes its coloration  and sustained vocal powers to 400  years of selective breeding.

The islands comprise two provinces, Santa  Cruz de Tenerife and Las Palmas, with an area of 2,876 sq mi (7,447 sq  km). The capital is Santa Cruz de Tenerife. Known in ancient times as the  �Fortunate Islands,� they were written about by both Plutarch and Pliny  the Elder. Believed to be the western limit of the world, they were visited  in the Middle Ages by Arabs, Genoese, Majorcans, Portuguese, and  French. They were taken by Castile (see Castile-Leon) in 1404, and their  indigenous inhabitants, the Guanche and Canario, were gradually con�  quered during the 15th century. The islands became a stop on the usual  route for Spanish trading vessels with the New World. Today agriculture  is an economic mainstay, as is an expanding tourist trade.</p><p>canasta \k3-'nas-t9\ Form of rummy, using two full decks, in which  players or partnerships try to meld groups of three or more cards of the  same rank and score bonuses for seven-card melds. Eleven cards are dealt  to each player, the undealt portion of the pack is placed on the table, and  the top card is turned up to start the discard pile. Each player in turn must  draw, may meld, and must discard one card. A hand ends when a player  melds his last card (goes out). Canasta originated in Uruguay in the late  1940s; its name (meaning �basket�) is probably a reference to the tray for  holding discards.</p><p>Canaveral Vko-'na-vo-roL, Cape Cape, eastern Florida, U.S. It is the  location of NASA�s John F.

His ferroconcrete structures are distinguished by thin,  curved shells that are extremely strong and economical; his imaginative  use of paraboloid barrel-vaulting helped dispel mistaken notions of the  limits of this material. Notable works include the expressionistic church  of Nuestra Senora de los Milagros in Mexico City (1955), with a hyper�  bolic paraboloid roof of ferroconcrete only 1.5 in.

The Greek church calls it  Hypapante (�Meeting�) in reference to Jesus� meeting there with Simeon,  to whom it had been revealed that he would not die before meeting the  Messiah. The festival is first documented in Jerusalem in the late 4th cen�  tury; the custom of observing it with lighted candles (the source of its  name) dates to at least the mid-5th century. The popular nonreligious  holiday Groundhog Day developed, in part, from the medieval tradition  that certain animals interrupted their hibernation on this day.</p><p>Candolle \ka n -'d6l\, Augustin (Pyrame de) (b.

He carried out a government-  commissioned botanical and agricultural survey of France (1806-12). In  1813 he published his most important work, Theorie elementaire de la  botanique, in which he contended that plant anatomy, not physiology, must  be the basis of classification, for which he coined the term taxonomy. He  introduced the concept of homologous parts for plants (following Cuvi�  er�s work on animals). From 1817 until his death he taught at the Uni�  versity of Geneva. He outlined systematic laws of botanical nomenclature  (1818-21); his taxonomy suffered from certain weaknesses, but he  achieved extensive subdivision of flowering plants, describing 161 fami�  lies of dicotyledons, and his system supplanted that of Carolus Linnaeus.  He completed seven volumes of a descriptive classification of all known  seed plants (from 1824).</p><p>Candomble \ l kan-dom- , bla\ Variant of Macumba, a syncretic Afro-  Brazilian religion most prominent in the Brazilian state of Bahia.

Roman losses exceeded 65,000 men, while the Carthaginians  lost only about 6,000.</p><p>Cannes \'kan\ City (pop., 1999: 67,304), southeastern France. Located  on the Mediterranean Sea southwest of Nice, it is an international resort.  Probably settled by Ligurians, it was occupied successively by Phocae-  ans, Celts, and Romans. In the 10th century the monks of Lerins built  fortifications to guard against Muslim sea raiders. Napoleon, on his return  from Elba in 1815, camped nearby. A resort since the 19th century, the  city is home to the Cannes Film Festival.</p><p>Cannes Film Festival \'kan\ Film festival held annually in Cannes,  France. First held in 1946 for the recognition of artistic achievement, the  festival came to provide a rendezvous for those interested in the art and  influence of the movies. Like other film festivals, it became an interna�  tional marketplace where producers and distributors could exchange  ideas, view films, and sign contracts. The phenomenon of international  coproduction arose at Cannes in the late 1940s. The festival was at times  the site of artistic contention as well, as in 1958-59, when advocates and  opponents of the French New Wave exchanged diatribes and manifestos.</p><p>cannibalism The usually ritualistic eating of human flesh by humans.  The term derives from the Spanish name (Canbales or Canfbales) for the  Carib people, first encountered by Christopher Columbus. Reliable first�  hand accounts of the practice are comparatively rare, causing some to  question whether full-blown cannibalism has ever existed. Most agree that  the consumption of particular portions or organs was a ritual means by  which certain qualities of the person eaten might be obtained or by which  powers of witchcraft and sorcery might be exercised. In some cases, a  small portion of the dead person was ritually eaten by relatives. Head�  hunters (see headhunting) sometimes consumed bits of the bodies or heads  of deceased enemies. The Aztecs apparently practiced cannibalism on a  large scale as part of the ritual of human sacrifice.</p><p>cannibalism In zoology, the eating of any animal by another member  of the same species. Certain ants regularly consume injured immatures  and, when food is scarce, eat healthy immatures; this practice allows the  adults to survive the food shortage and live to breed again. Male lions  taking over a pride may kill and eat the existing young. After losing her  cubs the mother will become impregnated by the new dominant male,  thereby ensuring his genetic contribution. Aquarium guppies sometimes  regulate their population size by eating most of their young.</p><p>canning Method of preserving food from spoilage by storing it in con�  tainers that are hermetically sealed and then sterilized by heat. The pro�  cess was invented in 1809 by Nicolas Appert (b. c. 1750�d. 1841) of  France, who used glass bottles. In the 19th century tin-coated iron cans  with soldered tops, bottoms, and seams were used, but in the early 20th  century these were replaced by tin-plated steel containers with interlock�  ing seams and polymer seals. In the later 20th century seamless alumi�  num cans (punched out from a single sheet) capped with a steel or  aluminum lid became common, particularly in the beverage industry. In  modern canning, food is passed under hot water or steam, transferred to  a sterile container, sealed inside, and subjected to heat sufficient to kill  any remaining microorganisms, cooking the food. The process preserves  most nutrients but often affects consistency and taste.</p><p>Canning, George (b. April 11, 1770, London, Eng.�d. Aug. 8, 1827,  Chiswick, near London) British politician. As a young man, he came  under the influence of William Pitt, who helped him win a seat in Parlia�  ment (1793) and a post as undersecretary for foreign affairs (1796-99).  Canning served twice as foreign secretary (1807-09, 1822-27); his poli�  cies included cutting England adrift from the Holy Alliance and recogniz�  ing the independence of the Spanish American colonies. He became prime</p><p>minister in 1827 but died a few  months later. He helped the Tory  Party take a more liberal view on  many questions of domestic, colo�  nial, and foreign policy.</p><p>Canning, Stratford, Viscount  Stratford (of Redcliffe) (b. Nov.</p><p>4, 1786, London, Eng.�d. Aug. 14,</p><p>1880, Frant, Sussex) British diplo�  mat. A cousin of George Canning, he  served as minister to Switzerland  (1814-18) and later to the U.S.</p><p>(1820-23). As ambassador to Con�  stantinople intermittently for almost  20 years, he exerted a strong influ�  ence on Turkish policy. He was  involved with the movement for  Greek independence from Turkey.</p><p>He later became friends with the  Ottoman sultan and encouraged the  Tanzimat program of reforms. He  supported Turkish resistance to Rus�  sian attempts to influence Ottoman  affairs and tried in vain to prevent the  Crimean War. He retired after leav�  ing Turkey in 1858.</p><p>cannon Long-range artillery piece, as distinguished from other big guns  such as the howitzer or mortar. Early cannons, appearing in Europe in the  15th century, were smooth-bored and forged of iron, weighed 6,000-8,000  lbs (2,800-3,600 kg) and were loaded through the muzzle. They were  mounted on wheeled carriages, which were thrown backward when the  cannon was fired. Rifled bores and breechloading were adopted in the later  19th century, and new mechanisms such as the hydraulic buffer absorbed  the recoil. Before 1850 ammunition was either cannister, grapeshot, or  round, solid cannonballs and black powder, but rifled bores made pos�  sible the use of elongated projectiles, which had a longer range. The  shrapnel shell was widely used in the 19th-20th century. Modern cannons,  of high-grade steel, are towed on split-trail carriages or are mounted on  tracked vehicles; a common calibre is 155 mm (6 in.). Many helicopters,  airplanes, and naval vessels are equipped with multibarreled, Gatling-type  rotary cannons firing 20-mm exploding shells.</p><p>Cannon, Joseph (Gurney) (b. May 7, 1836, Guilford county, N.C.,  U.S.�d. Nov. 12, 1926, Danville, Ill.) U.S. politician. He began practic�  ing law in Illinois in 1859. Elected to the U.S. House of Representatives  in 1872, he served 46 years (1873-91, 1893-1913, 1915-23). A staunchly  conservative Republican, he used his power as speaker (1903-11) in a  partisan manner. In 1910 a coalition of Democrats and insurgent Repub�  licans passed a resolution that made the speaker ineligible for member�  ship on the rules committee, the main source of his power. Personally  well liked, he was popularly known as �Uncle Joe.�</p><p>Cannon, Walter B(radford) (b. Oct. 19, 1871, Prairie du Chien,  Wis., U.S.�d. Oct. 1, 1945, Franklin, N.H.) U.S. neurologist and physi�  ologist. He was the first to use X rays in physiological studies. He also  investigated hemorrhagic and traumatic shock during World War I and  worked on methods of blood storage. He researched the emergency func�  tions of the sympathetic nervous system and homeostasis and sympathin,  an epinephrine-like substance released by certain neurons. With Philip  Bal'd he developed the Cannon-Bard theory, which proposed that emo�  tional and physiological responses to external situations arise simulta�  neously and that both prepare the body to deal with the situation.</p><p>Cano Vka-no\, Alonso (b. March 19, 1601, Granada, Spain�d. Sept.  3, 1667, Granada) Spanish painter, sculptor, and architect. He studied in  Sevilla with Francisco Pacheco and was active as court painter in Madrid  (1638-44). Despite a violent temperament, Cano produced serene and  elegant religious paintings and sculpture. He worked for much of his  career in Granada, where he designed the facade of the Granada Cathe�  dral (1667), one of the masterpieces of Spanish Baroque architecture. He  is often called the Spanish Michelangelo for the diversity of his talents.</p><p>canoe Lightweight boat pointed at both ends and propelled by one or  more paddles.

The birchbark canoe was first used by the</p><p>George Canning, painting by Sir Tho�  mas Lawrence and Richard Evans; in  the National Portrait Gallery, London.</p><p>COURTESY OF THE NATIONAL PORTRAIT GALLERY,  LONDON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>canoeing &#x25BA; canton I 327</p><p>Algonquian Indians in what is now the northeastern U.S. and Canada, and  its use passed westward. Canoes were often about 20 ft (6 m) in length,  though war canoes might be as long as 100 ft (30 m). The dugout canoe,  made from a hollowed-out log, was used by Indians in what is now the  southeastern U.S. and along the Pacific coast as far north as Canada, as  well as by peoples in Africa and New Zealand. Modern canoes are made  of wood, canvas over wood frames, aluminum, and molded plastic or  fibreglass. Most are open from end to end, but the kayak is also consid�  ered a canoe. See also canoeing.</p><p>canoeing Use of a canoe or kayak for recreation or competition. Both  types of boat are used in water touring, in speed competitions, and in  white-water sport, or navigation through rapids (which includes, in the  case of kayaks, ocean surf). The Scottish philanthropist John MacGregor  (1825-1892) is traditionally credited with establishing the modem out�  door activity of canoeing in the 1860s. Canoeing events became part of  the Olympic Games in 1936 (1948 for women). In addition to various  singles, pairs, and team still-water events for distance and speed, there are  white-water racing competitions and, for kayaks, slalom events involving  the use of gates similar to those of slalom skiing.</p><p>canon Musical form and compositional technique. Canons are charac�  terized by having a melody that is imitated at a specified time interval by  one or more parts, either at the same pitch or at some other pitch. Imi�  tation may occur in the same note values, in augmentation (longer notes),  or in diminution (shorter notes); in retrograde order (beginning at its end),  mirror inversion (each ascending melodic interval becoming a descend�  ing interval, and vice versa), or retrograde mirror inversion; and so on.  Canons range from folk rounds such as �Three Blind Mice� and �Frere  Jacques� to the massively complex canons of Johann Sebastian Bach.</p><p>canon law Body of laws established within Roman Catholicism, East�  ern Orthodoxy, independent churches of Eastern Christianity, and the  Anglican Communion for church governance. Canon law concerns the  constitution of the church, relations between it and other bodies, and mat�  ters of internal discipline. The ecclesiastical lawyer and teacher Gratian  published the first definitive collection of Roman Catholic canon law c.  1140; the Decretum Gratiani drew on older local collections, councils,  Roman law, and church fathers. The enlarged Corpus juris canonici  (�Body of Canon Law�) was published in 1500. A commission of cardi�  nals issued the new Codex juris canonici (�Code of Canon Law�) in 1917,  and a revised version was commissioned after the Second Vatican Coun�  cil and published in 1983. Following the Schism of 1054, the Eastern  Orthodox church developed its own canon law under the patriarch of  Constantinople. The Anglican, Coptic, and Ethiopian Orthodox churches  also formulated their own collections.</p><p>canonization Official act of a Christian church declaring a deceased  member worthy of veneration and entering his or her name in the canon  (authorized list) of saints. The cult of local martyrs was widespread in the  early church, and by the 10th century church authorities were consider�  ing the need for formal recognition of saints by Rome, a change that was  formalized by Gregory IX in the 13th century. Responsibility for beatifi�  cation (declaring a person worthy of limited veneration) was assigned to  the Roman Curia under Sixtus V (r. 1585-90). A candidate�s writings,  miracles, and reputation for sanctity are investigated: one official gathers  evidence in favor of beatification; another (the �devil�s advocate�) is  charged with seeing that the entire truth is made known about the can�  didate. Canonization requires proof of two miracles subsequent to beati�  fication. The process in the Eastern Orthodox Church is less formal;  popular devotion by the faithful serving as the usual basis for sainthood.</p><p>canopic jar In ancient Egyptian funerary ritual, a covered vessel of  wood, stone, pottery, or faience containing the embalmed viscera removed  from a body during mummification. First used during the Old Kingdom  (c. 2575-c. 2130 bc), the jars became more elaborate during the Middle  Kingdom (c. 1938-c. 1600 bc), when their lids were decorated with  sculpted human heads (probably representations of the deceased). From  the 19th dynasty until the end of the New Kingdom (1539-1075 bc), the  heads represented the four sons of Horus. During the 20th dynasty (1190�  1075 bc), the practice began of returning the viscera to the body, and the  art of canopic jars declined.</p><p>Canova, Antonio (b. Nov. 1, 1757, Possagno, Republic of Venice�d.  Oct. 13, 1822, Venice) Italian sculptor. Apprenticed to a sculptor at an  early age, he opened his own studio in Venice by 1775. In 1778-79 he  produced his first important sculpture, Daedalus and Icarus', the figures</p><p>were so realistic that he was accused of making plaster casts from live  models. He settled in Rome in 1779 and became strongly influenced by  Classical antiquity. Among his most important commissions were the  tombs of two popes, Clement XIII and Clement XIV. In 1802 he became  court sculptor to Napoleon I in Paris. In 1816 Pope Pius VII awarded him  the title of marquis of Ischia for arranging the return of Italian art looted  by the French. Canova also painted portraits and re-creations of paintings  discovered at Pompeii and Herculaneum. He dominated European sculpture  around the turn of the century and was of primary importance in the  development of the Neoclassical style in sculpture (see Classicism and  Neoclassicism).</p><p>Canso, Strait of or Canso Gut Channel, Nova Scotia, Canada. Sepa�  rating mainland Nova Scotia and Cape Breton Island, it is 4.5 mi (23 km)  long and 1 mi (2 km) wide, with depths of 200 ft (60 m). Since 1955 the  7,000-ft (2,100-m) Canso Causeway has linked Cape Breton with the  mainland. A navigation lock can handle most oceangoing vessels.</p><p>Cantabria \kan-'ta-bre-9\ Historical region, autonomous community  (pop., 2001: 535,131), and province, northern Spain. It borders the Bay  of Biscay and covers an area of 2,054 sq mi (5,321 sq km); its coastal hills  rise gradually into the Cantabrian Mountains. Its capital is Santander. The  Cantabri, an Iberian tribe, dominated the region until 19 bc, when they  were subdued by the Romans. Because of its isolation, the area was little  affected by the Iberian Moorish invasions (c. 8th�11th centuries). In the  Middle Ages, Cantabria came under Castilian influence. The region itself  was formerly known as Santander, and much of its population is centred  on the city of the same name. Mining is an important part of the economy.</p><p>Cantabrian Mountains \kan-'ta-bre-on\ Mountain range, northern  Spain. The mountains, which extend about 180 mi (300 km), are geo�  logically of similar origin to the Pyrenees, though classified as a separate  formation. They include many tall peaks, the highest being Torre de  Cerredo (8,787 ft, or 2,678 m), and thus form a more formidable barrier  than the Pyrenees. The region is economically important for its coal and  iron.</p><p>cantata Work for voice or voices and instruments of the Baroque era.  From its beginnings in early 17th-century Italy, both secular and religious  cantatas were written. The earliest cantatas were generally for solo voice  and minimal instrumental accompaniment. Cantatas soon developed a  dramatic character and alternating sections of recitative and aria, parallel�  ing the simultaneous development of opera, and they came to resemble  unstaged operatic scenes or acts. In Germany the Lutheran cantata devel�  oped more directly out of the expanding choral motet, and almost always  involved a chorus. A single chorale (hymn) often served as the basis for  an entire cantata, which might have up to 10 diverse numbers, including  duets, recitatives, and choral fugues. The most celebrated are the approxi�  mately 200 written by Johann Sebastian Bach. After c. 1750 the cantata  gradually declined.</p><p>Canterbury Historic city and administrative district (pop., 2001:  135,287), southeastern England. Located on the River Great Stour, the  site has been occupied since pre-Roman times; the Roman town of Durov-  ernum Cantiacorum was established after Claudius invaded Britain in ad  43. It has been an ecclesiastical metropolis of England since St. Augus�  tine of Canterbury founded a monastery there in 602 and later established  a cathedral. The cathedral was the scene of the murder of Archbishop St.  Thomas Becket in 1170. After his canonization in 1172, it became a pil�  grimage shrine; it is the destination of the pilgrims in Geoffrey Chaucer�s  Canterbury Tales. Canterbury was heavily bombed in World War II, but  the cathedral largely escaped damage. The cathedral and other historic  buildings were designated a UNESCO World Heritage site in 1988.</p><p>cantilever \'kan-t3-,le-v3r\ Projecting beam or other horizontal mem�  ber supported at one or more points but not at both ends. Some engineers  distinguish between a cantilever, supported at only one fixed end, and an  overhanging beam that projects beyond one of its end supports. The free,  unsupported end is capable of supporting a weight or surface, such as a  concrete slab. Any beam built into a wall with a projecting free end forms  a cantilever, which may carry a balcony, canopy, roof, or part of a build�  ing above. Cantilevering can be used for constructions as simple as book�  shelves or as complicated as bridges.</p><p>canton Political subdivision of Switzerland, France, and some other  European countries.

From 1759 to 1842, all foreign trade coming into China was confined to  Guangzhou and had to be conducted with authorized Chinese merchants.  Foreign merchants were confined to a small area outside the city wall and  were subject to Chinese law and other restrictions. British merchants�  complaints grew during the early 19th century, and, with Britain�s victory  in the first Opium War (1839-42), China was forced to abolish the sys�  tem.

In Judaism the hazzan (cantor) leads liturgical prayer and chant�  ing. In medieval Christianity the cantor had charge of a cathedral�s  music�specifically, of supervising the choir�s singing. The term also  designated the head of a college of church music.</p><p>Cantor, Eddie orig. Edward Israel Iskowitz (b. Jan. 31, 1892,  New York, N.Y., U.S.�d. Oct. 10, 1964, Hollywood, Los Angeles, Calif.)  U.S. comedian and singer. As a child, Cantor clowned and sang for coins on  street comers in his native New York City. He dropped out of elementary  school, could not keep a job because of his irrepressible clowning, and soon  went into vaudeville as a blackface song-and-dance man. He toured with  Florenz Ziegfeld�s Follies and the Shuberts. He appeared in several Broad�  way reviews, and from 1923 to 1926 he was a star in Kid Boots. From 1931  Cantor performed for 18 years on The Chase and Sanborn Hour as a  standup comedian. His films include Roman Scandals (1933) and Strike Me  Pink (1936). In the 1950s he hosted a television show.</p><p>Cantor \'kan-tor\, Georg (b. March 3, 1845, St. Petersburg, Russia�d.  Jan. 6, 1918, Halle, Ger.) German mathematician, founder of set theory.  He was the first to examine number systems, such as the rational numbers  and the real numbers, systematically as complete entities, or sets. This led  him to the surprising discovery that not all infinite sets are the same size.  In particular, he showed that the rational numbers could be put in a one-  to-one correspondence with the counting numbers; hence the set is count�  able. He also showed that no such correspondence is possible for the much  larger set of irrational numbers; hence they are known as an uncountable  set. His investigations led him to the classification of transfinite numbers,  which are, informally speaking, degrees of infinity.</p><p>cantus firmus Latin "fixed chant" Preexistent melody, such as a  plainchant (see Gregorian chant) excerpt, underlying a polyphonic musi�  cal composition (one consisting of several independent voices or parts).  In the 11th- and 12th-century organum, the tones of the plainchant melody  for such words as �alleluia� and �amen� were held by one voice (the  tenor), while another, more active, improvised line was added. Develop�  ments introduced by the Notre-Dame school of the late 12th and early 13th  centuries included rhythmic patterning of the added voice and the addi�  tion of two or three voices. The composition of nonliturgical words for  the added voice or voices in the 13th century resulted in the independent  motet. Cantus firmus technique remained the basis of most composition  of the 14th�15th centuries (though the �chant� was now often a secular  melody) and remained important in the 16th-century mass. It was later  codified in the pedagogical method called species counterpoint.</p><p>Canute Vko-'niitV the Great Danish Knut (d. Nov. 12, 1035) Danish  king of England (1016-35), Denmark (1019-35), and Norway (1028-35).  He helped his father, Sweyn I, invade England in 1013. Sweyn was  accepted as king of England after exiling King Ethelred II but died in 1014;  Canute returned and defeated Ethelred�s son to win the English throne in  1016. At first he ruled ruthlessly, killing English opponents and appointing  Danes in their places, but within a few years he had married Ethelred�s  widow and was granting earldoms to Englishmen. Canute proved an effec�  tive ruler who brought peace and prosperity to England, issued an impor�  tant law code, and became a strong supporter of the church. With English  help he secured the throne of Denmark on his brother�s death. His early  death and that of his sons led to the restoration of Ethelred�s dynasty.</p><p>canvas Stout cloth. Canvas (probably named for cannabis, or hemp), has  been made from hemp and flax fibres since ancient times to produce cloth</p><p>for sails. More recently it has also been made from tow, jute, cotton, and  mixtures of such fibres. Flax canvas is essentially of double warp (see  weaving), being invariably intended to withstand pressure or rough usage.  Articles made from canvas include camera and golf bags, running shoes,  tents, and mailbags. Tarred canvas is used for tarpaulins to cover goods.  Artists� canvas for painting is much lighter than sail canvas; those of the  best quality are made of cream or bleached flax fibre.</p><p>canvasback Diving duck ( Aythya valisineria), one of the most popular  game birds. The male weighs about 3 lb (1.4 kg). During the breeding  season he has a red head and neck and a black breast, with a white back  and sides finely lined in gray. In eclipse (nonbreeding) plumage, he  resembles the female, with a tan head and gray-brown back. Canvasbacks  breed in northwestern North America and winter along the coasts from  British Columbia and Massachusetts south to central Mexico. They pre�  fer the roots of wild celery (eelgrass) but will eat many other plants and  even some small animals.</p><p>canyon Very narrow, deep valley cut by a river through resistant rock  and having steep, almost vertical sides.

Cao Cao rose to prominence when he  suppressed the Yellow Turban rebellion in the last years of the Han. Though  the rebellion was suppressed, the dynasty was irreparably weakened, and  in the ensuing chaos Cao Cao occupied the strategic northern section of  China around the capital of Luoyang. His domain was known as the king�  dom of Wei (see Three Kingdoms). Confucian historians and popular leg�  ends alike describe him as the archetypal unscrupulous villain; he is  portrayed as such in the famous 14th-century novel Sanguozhi yanyi  (�Romance of the Three Kingdoms�). His son, Cao Pei, founded the Wei  dynasty (220-265/266).</p><p>Cao Dai \'kau-'dl\ Syncretist modern Vietnamese religious movement  with a strongly nationalist political character. Cao Dai draws on ethical  precepts from Confucianism, occult practices from Daoism, theories of  karma and rebirth from Buddhism, and hierarchical organization (includ�  ing a pope) from Roman Catholicism. It was formally established in 1926  by Ngo Van Chieu (1878-19267), a colonial administrator in French  Indochina who professed to have had a communication from the supreme  deity. The movement met with resistance from the Vietnamese govern�  ment both before and after the communist takeover in 1975. It was  reported to have some three million adherents in Vietnam and abroad in  the early 21st century.</p><p>Cao Zhan \'tsau-'jan\ or Ts'ao Chan (b. 17157, Jiangning, Jiangsu  province, China�d. Feb. 12, 1763, Beijing) Chinese novelist. He is the  author of Dream of the Red Chamber (1791), generally considered Chi�  na�s greatest novel. A partly autobiographical work written in the ver�  nacular, it describes in lingering detail the decline of a powerful family  and an ill-fated love between cousins. Cao finished at least 80 of its 120  chapters; it was completed after his death, probably by Gao E, about  whom little is known.</p><p>Capa, Robert orig.

If electric charge is transferred between  two initially uncharged conductors, they become equally (but oppositely)  charged. A potential difference is set up between them and some of the  electricity can be stored.

Separated from the mainland by the Strait  of Canso, it is 110 mi (175 km) long and up to 75 mi (120 km) wide, with  an area of 3,981 sc[ mi (10,311 sq km). It contains the Bras d'Or salt lakes.  Originally called lie Royale as a French colony, it later took the name of  its eastern cape, probably the first land visited by John Cabot on his  1497-98 voyage and probably named by Basque fishermen from Cap  Breton, France. It was ceded to the British by the 1763 Treaty of Paris and  joined to Nova Scotia. In 1784 it became a separate British crown colony,  but it was rejoined to Nova Scotia in 1820. In 1955 the island was linked  to the mainland by a causeway. Cape Breton Highlands National Park was  established in 1936. Tourism is an important industry on the island.</p><p>Cape buffalo Massive, black, horned buffalo ( Syncerus caffer), for�  merly found throughout sub-Saharan Africa but now greatly reduced in  number by disease and hunting. It is a gregarious animal of open or  scrub-covered plains and open forests. When wounded, it is regarded as  one of the most dangerous animals. It stands up to 5 ft (1.5 m) tall at the  shoulder, and bulls can weigh almost a ton (about 900 kg). Its heavy horns  typically curve downward, then up and inward.

The  Cape Cod Canal, cutting across the base of the peninsula, forms part of  the Atlantic Intracoastal Waterway. Named by an English explorer who  visited its shores in 1602 and took aboard a �great store of codfish,� Cape  Cod was the site, near Provincetown, of the Pilgrims� landing in 1620.  Extending into the warm Gulf Stream, it has coastal towns and villages  that become densely populated resorts in summer. In the 19th century  Provincetown was an active whaling port.

Occupying the southern  extremity of the African continent, it comprised the southern and west�  ern portions of South Africa; its capital was Cape Town. The black state  of Ciskei and parts of two others, Transkei and Bophuthatswana, lay within  its boundaries. Its name refers to the Cape of Good Hope, 30 mi (50 km)  south of Cape Town. The original inhabitants included Bantu, San, and  Khoekhoe peoples. Bartolomeu Dias, en route to India in 1488, became the  first European to visit the area. A colony was founded by the Dutch at  Table Bay in 1652; it was ceded to the British in 1814. It joined the Union  of South Africa in 1910 and the Republic of South Africa in 1961.

The mountainous  windward islands are craggy and furrowed by erosion; the flat leeward  islands are largely plains and lowlands. The archipelago is volcanic in  origin. Fogo Island has an active volcano that erupted in 1951; it is also  the location of the highest peak, which rises 9,281 ft (2,829 m). The other  main islands are Santo Antao, Boa Vista, and Sao Tiago. Cape Verde has  a developing mixed economy based largely on agriculture, though tour�  ism has been promoted. It is a republic with one legislative house; its  chief of state is the president and its head of government the prime min�  ister. The islands were uninhabited when Diogo Gomes sighted and named  Maio and Sao Tiago in 1460; in 1462 the first settlers landed on Sao Tiago,  founding the city of Ribeira Grande. The city�s importance grew with the  development of the slave trade, and its wealth attracted attacks so often  that it was abandoned in 1712. The prosperity of the Portuguese-  controlled islands vanished with the decline of the slave trade in the 19th  century, when they were made a coaling and submarine cable station. In  1951 the colony became an overseas province of Portugal. Many island�  ers preferred outright independence, which was granted in 1975.

Capek�s �black utopias,� works show�  ing the dangers of technological progress, include the cautionary play  R.U.R.: Rossum�s Universal Robots (1920), a depiction of a society  dependent on mechanical workers called robots (a term he coined from a  Czech word for forced labour). The comic fantasy The Insect Play (1921;  with his brother Josef) satirizes human greed. The Makropoulos Affair  (1922) was made into an opera by Leos JanAcek. Capek explored aspects  of knowledge in the novel trilogy Hordubal (1933), Meteor (1934), and  An Ordinary Life (1934).</p><p>caper Any of the low prickly shrubs that make up the genus Capparis  (family Capparaceae), of the Mediterranean region. The European caper-  bush (C. spinosa) is known for its flower buds, which are pickled in vin�  egar and used as a spicy condiment. The term caper also refers to one of  the pickled flower buds or young berries.

Capetians also ruled as dukes of Burgundy and Brittany, emperors  of Constantinople, counts of Artois and Provence, kings and queens of  Naples, and kings of Hungary and Navarre.</p><p>capillarity \,ka-p3-'lar-9-te\ Rise or fall of liquid in a small passage or  tube. When a glass tube of small internal diameter is inserted into water,  the surface water molecules are attracted to the glass and the water level  in the tube rises. The narrower the tube, the higher the water rises. The  water is said to �wet� the tube. Water will also be drawn into the fibres  of a towel, even if the towel is in a horizontal position. Conversely, if a  glass tube is inserted into mercury, the level of the liquid in the tube falls.  The mercury does not wet the tube. Capillarity is caused by the differ�  ence in attraction of the liquid molecules to each other and the attraction  of the liquid molecules to those of the tube.</p><p>capillary Vka-po-.ler-eX Any of the minute blood vessels that form net�  works where the arterial and venous circulation (see artery, vein) meet for  exchange of oxygen, nutrients, and wastes with body tissues. Capillaries  are just large enough for red blood cells to pass through in single file.  Their thin walls are semipermeable, allowing small molecules to pass</p><p>through in both directions. The smallest lymphatic vessels and minute bile  channels in the liver are also called capillaries.</p><p>capital In architecture, the crowning member of a column, pier, pilas�  ter, or other vertical form, providing a structural support and transition for  the horizontal member (entablature) or arch above. In Classical styles, the  capital is the architectural member that most readily identifies the order.  Simple stone capitals have been found in the earliest known pyramids of  ancient Egypt (c. 2890-2686 bc), at Saqqarah.</p><p>capital In economics, the stock of resources that are used to produce  other goods now and in the future. In classical economics the three fac�  tors of production are capital, labour, and land. Capital embodies the  man-made resources, which include the buildings, plant, equipment, and  inventories created by all three factors. In this sense, capital goods may  be contrasted with consumer goods. The creation of capital goods means  that consumption is forgone, resulting in saving. The flow of saving  becomes a flow of investment. Expenditures on education and training are  often referred to as investment in human capital (see Gary S. Becker).  Financial capital is the term given to the stocks and bonds issued in order  to finance the acquisition of capital goods.</p><p>capital gains tax Tax levied on gains realized from the sale or  exchange of capital assets. Though capital gains have been taxed in the  U.S. since the advent of the federal income tax, certain capital gains are  taxed less heavily than regular income, while others are exempted from  taxation. This preferential treatment is intended to encourage investment  and thereby stimulate economic growth. In theory the tax break encour�  ages investors to risk their capital in new ventures. Critics argue that pref�  erential treatment results in distorted patterns of investment because  regular income is converted into capital gains in order to avoid paying  income tax. See also corporate income tax.</p><p>capital goods See producer goods</p><p>capital levy Direct tax assessed simultaneously on the capital resources  of all persons possessing taxable wealth in excess of a minimum value  and paid at least partly out of capital resources. It aims at capturing a  substantial portion of the taxpayers� wealth to enable the government to  cope with a major emergency or to redistribute wealth. Capital levies were  adopted in many European nations after World Wars I and II.</p><p>capital punishment or death penalty Execution of an offender  sentenced to death after conviction by a court of law of a criminal offense.  Capital punishment for murder, treason, arson, and rape was widely  employed in ancient Greece, and the Romans also used it for a wide range  of offenses. It also has been sanctioned at one time or another by most of  the world�s major religions. In 1794 the U.S. state of Pennsylvania  became the first jurisdiction to restrict the death penalty to first-degree  murder, and in 1846 Michigan abolished capital punishment for all mur�  ders and other common crimes. In 1863 Venezuela became the first coun�  try to abolish capital punishment for all crimes. Portugal was the first  European country to abolish the death penalty (1867). By the mid-1960s  some 25 countries had abolished the death penalty for murder. During the  last third of the 20th century, the number of abolitionist countries  increased more than threefold. Despite the movement toward abolition,  many countries have retained capital punishment, and some have  extended its scope. In the U.S., three-fourths of the states and the federal  government retain the death penalty, and death sentences are regularly  carried out in China, Saudi Arabia, Singapore, and Iran. Supporters of the  death penalty claim that life imprisonment is not an effective deterrent to  criminal behaviour. Opponents maintain that the death penalty has never  been an effective deterrent, that errors sometimes lead to the execution of  innocent persons, and that capital punishment is imposed inequitably,  mostly on the poor and on racial minorities.</p><p>capitalism or free-market economy or free-enterprise sys�  tem Economic system in which most of the means of production are pri�  vately owned, and production is guided and income distributed largely  through the operation of markets. Capitalism has been dominant in the  Western world since the end of mercantilism. It was fostered by the Ref�  ormation, which sanctioned hard work and frugality, and by the rise of  industry during the Industrial Revolution, especially the English textile  industry (16th�18th centuries). Unlike earlier systems, capitalism used the  excess of production over consumption to enlarge productive capacity  rather than investing it in economically unproductive enterprises such as  palaces or cathedrals. The strong national states of the mercantilist era</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Capitol &#x25BA; Capuchin I 331</p><p>provided the social conditions, such as uniform monetary systems and  legal codes, necessary for the rise of capitalism. The ideology of classi�  cal capitalism was expressed in Adam Smith�s Wealth of Nations (1776),  and Smith�s free-market theories were widely adopted in the 19th cen�  tury. In the 20th century the Great Depression effectively ended laissez-faire  economics in most countries, but the demise of the state-run command  economies of eastern Europe and the former Soviet Union (see communism)  and the adoption of some free-market principles in China left capitalism  unrivaled (if not untroubled) by the beginning of the 21st century.</p><p>Capitol, United States Meeting place of the U.S. Congress. In 1792  a competition for its design was won by William Thornton (1759-1828);  his revised Federal-style design of 1795 was executed as the exterior of the  wings adjacent to the central rotunda. Benjamin H. Latrobe, as Surveyor of  Public Buildings (1803), followed Thornton�s conception of the exterior  but used his own interior designs; perhaps his best-known contribution  was his invention of tobacco-leaf and corn-cob capitals. After the British  set fire to the Capitol in 1814, Latrobe began its reconstruction, but  resigned in 1817. By 1827 his successor, Charles Bulfinch, had joined the  two wings and built the first dome and the rotunda. In 1850 Thomas Ustick  Walter (1804-1887) won a competition to expand the wings; he also  designed the 287-ft- (87-m-) high cast-iron dome (1855-66), which was  based on Michelangelo�s dome for St. Peter's Basilica. The marble and  sandstone building contains about 540 rooms and stands in a 131-acre  (53-hectare) park.</p><p>Capitol Reef National Park Park, south-central Utah, U.S. Occu�  pying 378 sq mi (979 sq km), it comprises great buttressed cliffs of  coloured Navajo sandstone extending for 100 mi (160 km) along the  western edge of the Waterpocket Fold. Established as a national monu�  ment in 1937, it became a national park in 1971. It is so named because  its rock towers reminded geologists of coral reefs, while its dome-shaped  formations suggest capitol architecture. The cliff walls are covered with  pre-Columbian petroglyphs.</p><p>Capone, Al(phonse) (b. Jan. 17, 1899, Brooklyn, N.Y., U.S.�d. Jan.  25, 1947, Palm Island, Fla.) U.S. gangster. Quitting school after the sixth  grade, he joined the James Street Boys gang, led by Johnny Torrio. In a  youthful fight in a brothel-saloon he was slashed across the left cheek,  prompting the later nickname �Scarface.� In 1919 he joined Torrio in  Chicago to help run prostitution there. When Torrio retired (1925),  Capone became the city�s crime czar, running gambling, prostitution, and  bootlegging rackets. He expanded his territory by killing his rivals, most  famously in the St. Valentine�s Day Massacre, in which members of the  Bugs Moran gang were machine-gunned in a garage on Feb. 14, 1929.  In 1931 Capone was convicted for income-tax evasion and sentenced to  11 years in prison; eventually he served time in the new Alcatraz prison  (see Alcatraz Island). Granted an early release from prison in 1939, in  part because he suffered from an advanced stage of syphilis, he died a  powerless recluse at his Florida estate.</p><p>Caporetto, Battle of (Oct. 24, 1917) Italian military disaster in World  War I in which Italian troops retreated before an Austro-German offen�  sive near Trieste on the Isonzo front (see Battles of the Isonzo).

His early  works, in the Southern Gothic tradition, include the novels Other Voices,  Other Rooms (1948) and The Grass Harp (1951) and the story collection  A Tree of Night (1949). His later journalistic style was exemplified in the  highly successful �nonfiction novel� In Cold Blood (1966), an account of  a multiple murder. Other works include the novella Breakfast at Tiffany�s  (1958; film, 1961), the musical House of Flowers (1954; with Harold  Arlen), and the collections The Dogs Bark (1973) and Music for Chame�  leons (1980).</p><p>Capp, Al orig.

Important as a Roman ally and client, it was annexed by the  emperor Tiberius in ad 17 and made a Roman province. With its command  over strategic passes in the Taurus Mountains, the area was a bulwark of  the Byzantine Empire until the 11th century.

A series of large paint�  ings (1599-1603) on the life of St. Matthew established him as the most  renowned and controversial painter in Rome of his era. Breaking with  conventional formulas used in depicting saints, he used ordinary people  as models and painted them with unforgiving realism; his inclination  against tradition gave new meaning to the interpretation of traditional  themes in religious painting. His use of tenebrism�dramatic, selective  illumination of form out of deep shadow to heighten the emotional ten�  sion, focus the details, and isolate the figures�became the most outstand�  ing feature of his style and a hallmark of the Baroque period. After c. 1600</p><p>he received many commissions,  including the monumental The  Deposition of Christ (1602-04) and  Death of the Virgin (1605-06),  which was refused by the Carmelites  because of the Virgin�s plebeian fea�  tures, bared legs, and swollen belly.</p><p>His reputation and income increased  despite harsh criticism and a turbu�  lent lifestyle. He had an enormous  impact on painting throughout  Europe.</p><p>caravan Group of merchants, pil�  grims, or travelers journeying  together, usually for mutual protec�  tion, in deserts or other hostile  regions. The camel was the most  common means of transport. Cara�  vans have been described since the  beginning of recorded history, and  they were a major factor in the  growth of settlements along their  routes. One caravan trail developed  into the Silk Road. During the height  of caravan travel, which lasted until the 19th century, a single caravan of  Muslim pilgrims journeying from Cairo and Damascus to Mecca might  employ as many as 10,000 camels.</p><p>caravansary \,kar-9-'van-s3-re\ or caravanserai \,kar-3-'van-s9-  ,ri\ Public building used for sheltering caravans and other travelers in the  Middle East. The structure is quadrangular in form and enclosed by a  massive wall that has small windows near the top and a few narrow air  holes near the bottom. The central court, surrounded by an arcade and  storerooms, is usually large enough to contain 300-400 camels. It is open  to the sky and has a well with a fountain basin in its center. There are  rooms upstairs for lodging.</p><p>caraway Dried fruit, commonly called the seed, of Carum carvi, a  biennial herb of the parsley family. Native to Europe and western Asia, it  has been cultivated since ancient times. It has a distinctive aroma and a  warm, slightly sharp taste. It is used as a seasoning, and the oil is used to  flavor alcoholic beverages and as a medicine.</p><p>carbamide See urea</p><p>carbide Inorganic compound, any of a class of chemical compounds in  which carbon is combined with a metal or semimetallic element. The  nature of the second element (its position in the periodic table) determines  the carbide�s type of bonding and its properties. Calcium carbide is use�  ful as a source of acetylene. Carbides of tungsten, silicon (see Carborun�  dum), and boron, called refractory carbides, are extremely hard, remain  stable when heated, and have a high melting point and chemical resis�  tance. They are used as abrasives and in cutting tools, as furnace linings,  and in other high-temperature applications. Iron carbide (cementite) is an  important constituent of steel and cast iron.</p><p>carbine Light, short-barreled rifle. The first carbines, from the muzzle�  loading muskets of the 18th century to the lever-action repeaters of the  19th, were chiefly cavalry weapons or saddle firearms for mounted fron�  tiersmen. During World War II carbine versions of standard bolt-action or  semiautomatic infantry rifles were carried by some officers, artillerymen,  and other specialists. Carbine versions of modern assault rifles (such as  the Russian AK-47 or the U.S. Ml 6 rifle) are intended for close-quarter  fighting, partly replacing the submachine gun. Carbine versions of hunting  and target rifles are also made.</p><p>carbohydrate Any member of a very abundant and widespread class  of natural organic compounds that includes sugars, starch, and cellulose.  They are commonly classified as monosaccharides (simple sugars; e.g.,  glucose, fructose), disaccharides (2-unit sugars; e.g., sucrose, lactose), oli�  gosaccharides (3-10 or so sugars), and polysaccharides (large molecules  with up to 10,000 monosaccharide units, including cellulose, starch, and  glycogen). Green plants produce carbohydrates by photosynthesis. In most  animals, carbohydrates are the quickly accessible reservoir of energy, and  oxidation (see oxidation-reduction) of glucose in tissues supplies energy  for metabolism. Many (but by no means all) carbohydrates have the gen-</p><p>Ajfe ** * f</p><p>The Deposition of Christ, oil on canvas  3y Caravaggio, 1602-04; in the Vati-  :an Museum.</p><p>iCALA/ART RESOURCE, NEW YORK</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>carbolic acid &#x25BA; carbonation I 333</p><p>eral chemical formula C�(H 2 0) n . The carbon (C) atoms are bonded to  hydrogen atoms (�H), hydroxyl groups (�OH; see functional group),  and carbonyl groups (�C=0), whose combinations, order, and geomet�  ric arrangement lead to a large number of isomers with the same chemi�  cal formula but different properties. The class is further enlarged because  each isomer has various derivatives: uronic acids, sugars with an oxidized  group; sugar alcohols, sugars with a reduced group; glycosides, com�  pounds of sugars with other molecules containing a hydroxyl group; and  amino sugars, sugars with an amino group (see amino acid).</p><p>carbolic acid \kar-'ba-lik\ or phenol Vfe-.nol, 'fe-,n6l\ Organic com�  pound, simplest member of the class of phenols. A colourless liquid with a  bland, sweetish odour, it is toxic and caustic. It is a high-volume industrial  chemical used chiefly in the manufacture of phenol-formaldehyde resins  (see formaldehyde; plastics), epoxy resins, nylon, herbicides, biocides, other  synthetic chemicals and pharmaceuticals, and dyes. It is also a solvent and  general disinfectant. The phenol coefficient is a number that expresses the  germicidal action of a chemical compared with that of phenol.</p><p>carbon Nonmetallic chemical element, chemical symbol C, atomic num�  ber 6. The usual stable isotope is carbon-12; carbon-13, another stable iso�  tope, makes up 1% of natural carbon. Carbon-14 is the most stable and  best known of five radioactive isotopes (see radioactivity); its half-life of  approximately 5,730 years makes it useful in carbon-14 dating and radi�  olabeling of research compounds. Carbon occurs in four known allotropes:  diamond, graphite, carbon black (amorphous carbon including coal, coke,  and charcoal), and hollow cage molecules called fullerenes. Carbon forms  more compounds than all other elements combined; several million car�  bon compounds are known. Each carbon atom forms four bonds (four  single bonds, two single and one double bond, two double bonds, or one  single and one triple bond) with up to four other atoms. Multitudes of  chain, branched, ring, and three-dimensional structures can occur. The  study of these carbon compounds and their properties and reactions is  organic chemistry (see organic compound). With hydrogen, oxygen, nitro�  gen, and a few other elements whose small amounts belie their important  roles, carbon forms the compounds that make up all living things: pro�  teins, CARBOHYDRATES, LIPIDS, and NUCLEIC ACIDS. BIOCHEMISTRY is the Study of  how those compounds are synthesized and broken down and how they  associate with each other in living organisms. Organisms consume car�  bon and return it to the environment in the carbon cycle. Carbon dioxide,  produced when carbon is burned and from biological processes, makes up  about 0.03% of the air, and carbon occurs in Earth�s crust as carbonate  rocks and the hydrocarbons in coal, petroleum, and natural gas. The oceans  contain large amounts of dissolved carbon dioxide and carbonates.</p><p>carbon cycle Circulation through nature of carbon in the form of the  simple element and its compounds. The source of carbon in living things  is carbon dioxide (C0 2 ) from air or dissolved in water. Algae and green  plants (producers) use C0 2 in photosynthesis to make carbohydrates, which  in turn are used in the processes of metabolism to make all other compounds  in their tissues and those of animals that consume them. The carbon may  pass through several levels of herbivores and carnivores (consumers). Ani�  mals and, at night, plants return the C0 2 to the atmosphere as a by-product  of respiration. The carbon in animal wastes and in the bodies of organisms  is released as C0 2 in a series of steps by decay organisms (decomposers),  chiefly bacteria and fungi (see fungus). Some organic carbon (the remains  of organisms) has accumulated in Earth�s crust in fossil fuels, limestone,  and coral. The carbon of fossil fuels, removed from the cycle in prehis�  toric times, is being returned in vast quantities as C0 2 via industrial and  agricultural processes, some accumulating in the oceans as dissolved car�  bonates and some staying in the atmosphere (see greenhouse effect).</p><p>carbon dioxide Inorganic compound, a colourless gas with a faint,  sharp odour and a sour taste when dissolved in water, chemical formula  C0 2 . Constituting about 0.03% of air by volume, it is produced when  carbon-containing materials burn completely, and it is a product of fer�  mentation and animal respiration. Plants use C0 2 in photosynthesis to make  carbohydrates. C0 2 in Earth�s atmosphere keeps some of the Sun�s energy  from radiating back into space (see greenhouse effect). In water, C0 2 forms  a solution of a weak acid, carbonic acid (H 2 C0 3 ). The reaction of C0 2  and ammonia is the first step in synthesizing urea. An important industrial  material, C0 2 is recovered from sources including flue gases, limekilns,  and the process that prepares hydrogen for synthesis of ammonia. It is  used as a refrigerant, a chemical intermediate, and an inert atmosphere;  in fire extinguishers, foam rubber and plastics, carbonated beverages (see  carbonation), and aerosol sprays; in water treatment, welding, and cloud</p><p>seeding; and for promoting plant growth in greenhouses. Under pressure  it becomes a liquid, the form most often used in industry. If the liquid is  allowed to expand, it cools and partially freezes to the solid form, dry ice.</p><p>carbon-14 dating or radiocarbon dating Method of determin�  ing the age of once-living material, developed by U.S. physicist Willard  Libby in 1947. It depends on the decay of the radioactive isotope carbon-14  (radiocarbon) to nitrogen. All living plants and animals continually take  in carbon: green plants absorb it in the form of carbon dioxide from the  atmosphere, and it is passed to animals through the food chain. Some of  this carbon is radioactive carbon-14, which slowly decays to the stable  isotope nitrogen-14. When an organism dies it stops taking in carbon, so  the amount of carbon-14 in its tissues steadily decreases. Because  carbon-14 decays at a constant rate, the time since an organism died can  be estimated by measuring the amount of radiocarbon in its remains. The  method is a useful technique for dating fossils and archaeological speci�  mens from 500 to 50,000 years old and is widely used by geologists,  anthropologists, and archaeologists.</p><p>carbon monoxide Inorganic compound, a highly toxic, colourless,  odourless, flammable gas, chemical formula CO. It is produced when car�  bon (including coal and coke) or carbon-containing fuel (including petro�  leum hydrocarbons; e.g., gasoline, fuel oil) does not burn completely to  carbon dioxide, because of insufficient oxygen. CO is present in the exhaust  gases of internal combustion engines and furnaces. It is toxic because it  binds to hemoglobin in blood much more strongly than does oxygen and  thus interferes with transport of oxygen from lungs to tissues (see hypoxia;  respiration). Symptoms of CO poisoning range from headache, nausea, and  syncope to coma, weak pulse, respiratory failure, and death. CO is used  industrially as a fuel and in synthesis of numerous organic compounds,  including methanol, ethylene, and aldehydes.</p><p>carbon steel Alloy of iron and carbon in which the carbon content may  range from less than 0.015% to slightly more than 2%. Adding this tiny  amount of carbon produces a material that exhibits great strength, hard�  ness, and other valuable mechanical properties. Carbon steels account for  about 90% of the world�s steel production. They are used extensively for  automobile bodies, appliances, machinery, ships, containers, and the  structures of buildings. Carbon steel, formerly made by the Bessemer, cru�  cible, or open-hearth process, is now made by the basic oxygen process, or  by an arc furnace.</p><p>Carbonari \,kar-b3-'na-re\ (Italian dialect: �Charcoal Burners�) Mem�  bers of a secret society (the Carbonaria) in early-19th-century Italy. Advo�  cating liberal and patriotic ideas, the Carbonari favored constitutional and  representative government and aimed to protect Italian interests against  foreigners. They helped lead the unsuccessful revolts of 1820 and 1831  and were gradually absorbed into the Young Italy movement. Their influ�  ence prepared the way for the Risorgimento.</p><p>carbonate Any member of two classes of chemical compounds�one  inorganic and the other organic�that are derived from carbon dioxide  (C0 2 ) or its water solution, carbonic acid (H 2 C0 3 ). Inorganic carbonates  (MC0 3 or M 2 C0 3 , where M is a metal atom of, e.g., calcium or sodium)  are salts of carbonic acid. The shells and other hard parts of shellfish are  calcium carbonate, as is the limestone they turn into. Many other miner�  als, including calcite, dolomite, and aragonite, consist of or contain car�  bonates. Sodium carbonate is one of the world�s most important basic  chemical commodities. Organic carbonates are esters of carbonic acid and  various alcohol groups (methyl, ethyl, or phenyl). These are liquids used  as solvents and to synthesize plastics and other compounds.</p><p>carbonate mineral Any member of a family of minerals that con�  tains the carbonate ion, C0 3 2- , as the basic structural unit. The carbon�  ates are among the most widely distributed minerals in the earth�s crust;  the most common are calcite, dolomite, and aragonite. Dolomite replaces  calcite in limestones; when this replacement is extensive, the rock is called  dolomite. Other relatively common carbonate minerals are siderite, rhodo-  chrosite, strontianite (strontium-rich); smithsonite (zinc-rich); witherite  (barium-rich); and cerussite (lead-rich).</p><p>carbonation Addition of carbon dioxide gas to a beverage, imparting  sparkle and a tangy taste and preventing spoilage.

All the land-  masses drew closer together as a result of tectonic plate movements. The  supercontinent Gondwana occupied much of the Southern Hemisphere.  By the end of the period, present-day North America, Greenland, and  northern Europe were also part of Gondwana. Siberia and China (includ�  ing Southeast Asia) remained individual continents located at high lati�  tudes in the Northern Hemisphere. During this period, swamp forests  became widespread, and enormous coal deposits formed. Plants made  great advances in the complex forests, and vertebrates were undergoing  extensive evolution.

The fourth bond on the carbon links it to a  hydrogen (H) atom (for formic acid), a methyl (�CH 3 ) group (for acetic  acid), or another natural or synthetic monovalent group. Carboxylic acids  occur widely in nature. In fatty acids, the fourth group is a hydrocarbon  chain. In aromatic acids (see aromatic compound), it is a ring-structured  hydrocarbon. In amino acids, it contains a nitrogen atom. Carboxylic acids  participate in chemical reactions as acids, usually fairly weak. Many car�  boxylic acids (acetic acid, citric acid, lactic acid) are intermediates in  metabolism and can be found in natural products; others (e.g., salicylic acid)  are used as solvents and to prepare many chemical compounds. Important  carboxylic-acid derivatives include esters, anhydrides, amides, halides (see  halogen), and salts (see soap).</p><p>carburetor \'kar-b3-,ra-t3r\ Device for supplying a spark-ignition  engine with a mixture of fuel and air. Carburetors are used in small gaso�  line engines, such as lawn mowers and chainsaws. Once an essential com�  ponent in all gasoline engines, automobile carburetors were displaced by  electronic fuel injection systems from the late 1970s through 1990. Car�  buretors for automobile engines usually contained a storage chamber for  liquid fuel, a choke, an idling jet, a main jet, an airflow restriction, and  an accelerator pump. The quantity of fuel in the storage chamber was  controlled by a valve actuated by a float. The choke, a butterfly valve,  reduced the intake of air so that a fuel-rich charge was drawn into the  cylinders when a cold engine was started. As the engine warmed up, the  choke was gradually opened. Reduced pressure near the partially closed  throttle valve caused the fuel to flow from the idling jet into the intake  air. Further opening the throttle valve activated the main fuel jet. Then the  venturi-shaped airflow restriction created reduced pressure, drawing fuel  from the main jet into the airstream at a rate related to the airflow so that  a nearly constant fuel-air ratio was obtained. The accelerator pump  injected fuel into the inlet air when the throttle was opened suddenly.

The combination of hard surface and soft  interior withstands very high stress and fatigue, and also offers low cost  and superior flexibility in manufacturing. To carburize, the steel parts are  placed in a carbonaceous environment (with charcoal, coke, and carbon�  ates, or with carbon dioxide, carbon monoxide, methane, or propane) at  a high temperature for several hours. The carbon diffuses into the surface  of the steel, altering the crystal structure of the metal. Gears, ball and roller  bearings, and piston pins are often carburized.</p><p>Carcassonne \,kar-ka-'s6n\ ancient Carcaso City (pop., 1999:  43,950), southwestern France.

The cardinals�  duties include electing the pope, acting as his principal counselors, and  aiding in the governance of the Roman Catholic Church. Cardinals serve  as officers of the Roman Curia, bishops of major dioceses, and papal envoys.  Since 769 only cardinals have been eligible to become pope, and since  1059 the pope has been elected only by cardinals. The first cardinals were  the deacons of the seven regions of Rome. Their present-day successors  are known as cardinal deacons. Cardinal bishops are the successors of the  bishops of the sees just outside Rome and of the patriarchal sees of the  Eastern Catholic Church. Cardinal priests are the bishops of important  sees around the world and constitute the most numerous order of cardi�  nals. The number of cardinals was limited to 70 for nearly 400 years until  1958, when John XXIII (1958-63) eliminated the restriction. Under Paul  VI (1963-78) there were 145 cardinals, and under John Paul II (1978�  2005) there were 182. With the increase in the size of the cardinalate came  new restrictions imposed by the popes. Paul VI directed that cardinals  who do not resign by age 75 relinquish the right to vote for a pope when  they reach 80. He also limited the number of voting cardinals to 120, a  restriction confirmed during the pontificate of John Paul II.

Cotton, wool, waste silk, and man-made staple are subjected  to carding. Carding produces a thin sheet of uniform thickness that is then  condensed to form a thick, continuous, untwisted strand called sliver.  When very fine yarns are desired, carding is followed by combing, a pro�  cess that removes short fibres, leaving a sliver composed entirely of long  fibres, all laid parallel and smoother and more lustrous than uncombed  types. Carded and combed sliver is then spun.</p><p>carding machine Machine for carding textile fibres.

Feb. 16, 1907, Bologna, Italy) Italian poet. He taught  literary history in Bologna for 40 years and in later years served as a sena�  tor. He opposed the prevailing Romanticism and advocated a return to  classical models of prosody, but his rhetorical tirades provoked resistance  to reform. His best volumes of verse, The New Lyrics and The Barbarian  Odes (1887), contain evocations of landscape, memories of childhood,  and representations of the glory of ancient Rome.

His  novels, more realistic but laced with black humour, include Bliss (1981),  Illywhacker (1985), Oscar and Lucinda (1988, Booker Prize), The  Unusual Life of Tristan Smith (1994), Jack Maggs (1997), and True His�  tory of the Kelly Gang (2000; Booker Prize, 2001).</p><p>cargo cult Any religious movement based on the observation by local  residents of the delivery of supplies by ship and aircraft to colonial offi�  cials. Cargo cults were observed chiefly in Melanesia in the late 19th and  early 20th centuries. They were characterized by the expectation of a new  age of blessing and prosperity to be initiated by the arrival of a special  �cargo� of goods from supernatural sources. Such beliefs may have  expressed traditional millennial ideas, often revived by the teaching of  Christian missions.</p><p>Caria \'kar-e-o\ Ancient district, southern Anatolia. It was one of the  most thoroughly Hellenized districts in ancient Anatolia; its territory  included Greek cities along the shore of the Aegean Sea and a mountain�  ous interior bounded by Lydia, Phrygia, and Lycia. Absorbed first by Lydia,  it later was annexed (4th century bc) by the Persian Achaemenian Empire,  one of whose governors, Mausolus, transferred its capital from Mylasa to  Halicarnassus. Taken from Persia in 334 bc by Alexander the Great, it was  incorporated into the Roman province of Asia in 129 bc.</p><p>Carib Vkar-ob\ American Indian people who inhabited the Lesser Antilles  and parts of the South American coast at the time of the Spanish conquest.  The Island Carib (now extinct) were a warlike, individualistic people who  reportedly practiced cannibalism (the term derives from their name). Carib  groups on the mainland, some of whom still survive, lived in the Guianas  and as far south as the Amazon River; they subsisted by hunting and grow�  ing crops and were less aggressive than their island relatives.</p><p>Cariban Vkar-e-bonN languages Large family of South American  Indian languages. It has an estimated 43 members; nearly half are now  extinct, and most of the remainder have very few speakers. Most Cariban  languages are spoken in southern Venezuela, the Guianas, and Brazil north  of the Amazon, though several have strayed far from this area. Cariban  incursions into the mainly ARAWAKAN-speaking Antilles at the time of  Columbus provided European languages with the words Carib (hence,  Caribbean) and cannibal, both perhaps from a proto-Cariban form mean�  ing �Indian, person.�</p><p>Caribbean Sea Arm of the Atlantic Ocean. It covers about 1,049,500  sq mi (2,718,200 sq km) and washes the northern coast of South America,  eastern Central America, and eastern Mexico. It reaches its greatest known  depth, about 25,000 ft (7,500 m), in Cayman Trench, between Cuba and  Jamaica. Its generally tropical climate varies, depending on mountain  elevations, water currents, and trade winds. The economies of its island  countries, including Saint Kitts and Nevis, Dominica, Saint Lucia, and  Barbados, are greatly dependent on tourism; the region is one of the  world�s principal winter resort areas.

They are usually gray�  ish or brownish with lighter underparts but may be whitish or nearly black.  Their herds are famous for their seasonal migration between summer and  winter ranges. Their staple winter food is a lichen, popularly called rein�  deer moss, which they reach by scraping the snow away with their feet.  In summer they also eat grasses and saplings. See also reindeer.</p><p>caricature Vkar-i-ko-.chuA Comically distorted drawing or likeness  intended to satirize or ridicule its subject. The word, derived from the  Italian caricare (�to load or charge�), was probably coined by the Car�  racci family, who defended the practice as a counterpart to idealization. In  the 18th century the caricature became connected with journalism and was  put to virulent use by political commentators. In the 1880s photo-process  engraving made it possible to produce and illustrate daily newpapers  cheaply, bringing caricatures to the general public. In the 20th century  caricature increasingly moved into the editorial, sports, and theatrical sec�  tions of newspapers. Important caricaturists include Jacques Callot,  George Cruikshank, Honore Daumier, Gustave Dore, and Al Hirschfeld.</p><p>caries \'kar-ez\ or tooth decay Localized disease that causes decay  and cavities in teeth. It begins at the tooth�s surface and may penetrate  the dentin and the pulp cavity. Microorganisms in the mouth are believed  to consume sugars and produce acids that eat away at tooth enamel. The  dentin�s protein structure is then destroyed by enzymes. Diet, general  health, structural tooth defects, and heredity affect the risk of having car�  ies. Prevention involves avoiding excessive sweets, brushing and flossing  the teeth, and having regular dental care. Treatment includes restoration  of teeth with cavities. Fluoridation of water can reduce the occurrence of  caries by as much as 65%.</p><p>carillon \'kar-3-,lan\ Musical instrument consisting of at least 23 cast  bronze bells tuned in chromatic order.

He determined that levodopa, a sub�  stance that the brain uses to make dopamine, could be employed as a  treatment for parkinsonism. His work also contributed to an understanding  of the relationship between neurotransmitters and mental states such as  clinical depression, which led to new antidepressant drugs, including  Prozac.

It originated  c. 1155 on Mount Carmel in Palestine, where a number of former pil�  grims and crusaders began to live as hermits. Their rule was written by  St. Albert, Latin patriarch of Jerusalem, and approved by Pope Honorius  III in 1226. As Muslim incursions made Palestine increasingly unsafe, the  Carmelites scattered to Cyprus, Sicily, France, and England. In England  and Western Europe the order transformed itself from a group of hermits  into one of mendicant friars. The first institution of Carmelite nuns was  founded in 1452. St. Teresa of Avila and St. John of the Cross reempha�  sized the strictness and austerity of Carmelite traditions, establishing Dis�  eased (barefoot) Carmelite orders in 1562 and 1569, which gave rise to  an independent order in 1593. Both the reformed and the original orders  suffered greatly during the French Revolution and the Napoleonic era, but  they were later restored in most of Western Europe as well as in the Middle  East, Latin America, and the U.S.</p><p>Carmichael, Hoagy orig.

While studying law in Indiana, he met  many jazz musicians, including Bix Beiderbecke, who recorded Carmicha�  el�s first composition, �Riverboat Shuffle� (1924). The relaxed tuneful�  ness of later songs such as �Georgia (Georgia on My Mind),� �Rockin�  Chair,� and �Lazy River� gave them a universal appeal. For Hollywood  films he wrote �Thanks for the Memory,� �Two Sleepy People,� �Heart  and Soul,� and �In the Cool, Cool, Cool of the Evening� (1951, Acad�  emy Award). His �Stardust� is reputedly the most recorded popular song  of all time.

May 18, 1891, Ronsdorf, Ger.�d. Sept. 14, 1970,  Santa Monica, Calif., U.S.) German-born U.S. philosopher. He earned a  doctorate in physics at the University of Jena in 1921. In 1926 he was  invited to join the faculty of the University of Vienna, where he soon  became an influential member of a group of philosophers, mathemati�  cians, and scientists known as the Vienna Circle. Out of their discussions  developed the basic ideas of logical positivism. Carnap immigrated to the  U.S. in 1935 and taught at the University of Chicago (1936-52). After  two years at the Institute for Advanced Study at Princeton (1952-54), he  joined the faculty of the University of California at Los Angeles, where  he remained until his death. Carnap sought to give the basic thesis of  empiricism �that all concepts and beliefs about the world ultimately derive  from immediate experience�a precise interpretation, construing it as a  logical thesis about the evidential grounding of empirical knowledge. For  Carnap, empiricism is the doctrine that the terms and sentences that  express assertions about the world are �reducible� in a clearly specifiable  sense to terms and sentences describing the immediate data of experience.  His major works include The Logical Structure of the World (1928), The  Logical Syntax of Language (1934), Introduction to Semantics (1942),  Meaning and Necessity (1947), and The Logical Foundations of Prob�  ability (1950).</p><p>carnation Herbaceous plant (.

This success was followed  by Bizarre, Bizarre (1937), Port of Shadows (1938), and Daybreak (1939),  works of poetic realism that were the fruit of his collaboration with screen�  writer Jacques Prevert. During the Nazi occupation he made The Devil�s  Envoys (1942) and later his masteipiece, The Children of Paradise (1945),  which chronicled life in the theatre and celebrated the French spirit.

The  son of a Scottish weaver, he emi�  grated to the U.S. with his family in  1848. A job in a telegraph office led  to his early career with the Pennsyl�  vania Railroad Co., and his canny  investments made him wealthy by  age 30. In 1872-73 he founded the  steelworks near Pittsburgh, Pa., that  evolved into the Carnegie Steel Co.  in 1889. By adopting technological  innovations such as the open-hearth  furnace and by increasing efficiency  through vertical integration, Carnegie  built a vast enterprise that dominated  the U.S. steel industry. In 1901 he  sold his company to J.P. Morgan,  and it became part of U.S. Steel. Andrew Carnegie  Believing that the affluent were brown brothers  obliged to use their surplus wealth</p><p>for the improvement of mankind, Carnegie retired to devote himself to  philanthropy, giving hundreds of millions of dollars to libraries and uni�  versities, including Carnegie Mellon University, and endowing such orga�  nizations as the Carnegie Institute of Pittsburgh and the Carnegie Corp.  of New York, the largest of all his foundations.</p><p>Carnegie, Dale orig. Dale Carnegey (b. Nov. 24, 1888, Maryville,  Mo., U.S.�d. Nov. 1, 1955, Forest Hills, N.Y.) U.S. lecturer and author.  Born into poverty, he worked as a traveling salesman and an actor before  he began teaching public speaking at a YMCA in New York City in 1912.  His classes were extremely successful, and he was soon lecturing to  packed houses. To standardize his teaching methods he began publishing  pamphlets, which he collected into book form as Public Speaking: A  Practical Course for Business Men (1926). His hugely popular How To  Win Friends and Influence People (1936) won him a national following;  like most of his books, it reveals little that was unknown about human  psychology but stresses that an individual�s attitude is crucial. The Dale  Carnegie Institute subsequently established hundreds of chapters through�  out the country.</p><p>cornelian \kar-'ne-le-on\ or cornelian Translucent, semiprecious  variety of the silica mineral chalcedony that owes its red to reddish brown  colour to the incorporation of small amounts of iron oxide. A closely  related variety of chalcedony, sard, differs only in the shade of red. Car-  nelian was highly valued and used in rings and signets by the Greeks and  Romans, some of whose intaglios have retained their high polish better  than those made from harder stones. Carnelian is mined principally in  India, Brazil, and Australia. Its physical properties are those of quartz.</p><p>Carniola Region, western Slovenia. It is located northeast of the head  of the Adriatic Sea and includes a mountainous area. Its chief town is  Ljubljana. It was part of the Roman province of Pannonia in ancient times  and was occupied by the Slovenes in the 6th century ad. In the 13th cen�  tury it became part of the Holy Roman Empire. In 1335 it became a pos�  session of the Austrian Habsburgs, who held it as a duchy until 1849, when  it was recognized as an Austrian crown land (1849-1918). After World  War I it was divided between Italy and the new Kingdom of Serbs, Croats,  and Slovenes (later Yugoslavia); it was incorporated entirely into Yugo�  slavia by a 1947 treaty. When Yugoslavia was fragmented in the 1990s,  Carniola was included in Slovenia.</p><p>carnival Final celebration before the fasting and austerity of Lent in  some Roman Catholic regions. The most famous and probably most exu�  berant carnival is that of Rio de Janeiro, which is celebrated with masked</p><p>balls, costumes, and parades; the best-known U.S. celebration is Mardi  Gras in New Orleans. The first day of carnival season varies with local  traditions, but carnival usually ends on Shrove Tuesday, the day before  the start of Lent.</p><p>carnivore Any meat-eating animal, but especially any member of the  order Carnivora, consisting of 12 families of primarily predatory mam�  mals: Canidae (e.g., dogs), Ursidae (bears), Procyonidae (raccoons), Mus-  telidae (weasels), Mephitidae (skunks), Viverridae (civets), Herpestidae  (mongooses), Hyaenidae (hyenas), Felidae (cats), Otariidae and Phocidae  (seals), and Odobenidae (the walrus). Though most carnivores eat only  meat, some rely heavily on vegetation (e.g., the panda). Most have a com�  plex tooth structure and a lower jaw that can move only vertically but can  exert great power. The earliest carnivores, which probably evolved from  an insectivorous ancestor, appeared during the Paleocene Epoch (about  65-55 million years ago). Carnivores are highly intelligent.</p><p>carnivorous plant Any of about 400 diverse species of plants spe�  cially adapted for capturing insects and other tiny animals by ingenious  pitfalls and traps and for digesting the nitrogen-rich animal proteins to  obtain nutrients. These adaptations are thought to enable such plants to  survive under otherwise marginal or hostile environmental conditions.  The conspicuous trapping mechanism (a leaf modification) draws the  prey�s attention to the plant. More than half the species belong to the  family Lentibulariaceae, most being bladder worts. The remainder belong  to several families composed of the pitcher plants, sundews, and flytraps  (see Venus's-flytrap). Most are found in damp heaths, bogs, swamps, and  muddy or sandy shores where water is abundant and where nitrogenous  materials are often scarce or unavailable because of acid or other  unfavourable soil conditions. The smallest Drosera species are often hid�  den among the moss of a sphagnum bog; most carnivorous plants are  small herbaceous perennials. Some become large shrubby vines.</p><p>carnosaur Any of the large carnivorous dinosaurs, a branch of thero-  pod dinosaurs that evolved into predators of large herbivorous dinosaurs.  Carnosaurs were massive animals with short necks, large skulls, and wide,  gaping mouths equipped with formidable teeth. They walked on two legs.  Tyrannosaurs were the largest of all carnosaurs.

Aug. 2, 1823, Magdeburg, Prussian  Saxony) French statesman and administrator in successive governments  of the French Revolution. He entered the army as an engineer (1773) and  was elected to the Legislative Assembly in 1791. As a leading member  of the Committee of Public Safety and the Directory, he helped mobilize the  Revolutionary armed forces and materiel, and he was lauded as the �Orga�  nizer of Victory.� During the Coup of 18 Fructidor he fled France to escape  arrest. He returned after Napoleon rose to power and served him in vari�  ous offices, including minister of the interior during the Hundred Days.</p><p>Carnot \kar-'no\, (Nicolas-Leonard-) Sadi (b. June 1, 1796, Paris,  France�d. Aug. 24, 1832, Paris) French scientist, known for describing  the Carnot cycle. Son of Lazare Carnot, he was an army officer most of  his life. Convinced that Britain�s advanced steam engines and France�s  inadequate use of steam were factors in Napoleon�s downfall, he wrote a  nontechnical essay on steam engines (1824). He subsequently developed  a theory of heat engines, predicting that efficiency depends only on the  temperature of the hottest and coldest parts and not on the substance  (steam or any other fluid) that drives the mechanism. Though adopted  slowly, his theory was eventually incorporated into the general theory of  THERMODYNAMICS.</p><p>Carnot, (Marie-Francois-) Sadi (b. Aug. 11, 1837, Limoges,  France�d. June 24, 1894, Lyon) French politician. Grandson of Lazare  Carnot and son of Sadi Carnot, he worked as a government engineer  before turning to politics. After serving as minister of public works (1880�  81) and finance (1885-87), he was elected in 1887 as fourth president of  the Third Republic. He competently handled the plots by Georges Boulanger,  anarchist agitation, and the Panama Canal scandals, and retained his popu�  larity through 10 different governments but was assassinated in 1894 by  an Italian anarchist.</p><p>Carnot cycle In heat engines, the ideal cycle of changes of pressures  and temperatures of a working fluid, such as steam or ammonia, conceived  by Sadi Carnot. It is the standard of performance of all heat engines oper�  ating between a high and a low temperature. In the cycle, the working</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>340 I Carnuntum &#x25BA; carpal tunnel syndrome</p><p>fluid undergoes four successive changes: (1) the fluid receives heat,  expanding at high temperature; (2) it delivers work during the reversible  adiabatic expansion (it changes in volume or pressure without losing or  gaining heat); (3) it rejects heat (to the heat sink) during compression at  low temperature; and (4) it receives work during the reversible adiabatic  compression. The efficiency is determined by the difference between the  temperatures of the heat source and the heat sink divided by the tempera�  ture of the heat source.

It was used as a base by Marcus Aurelius in his campaign  against the Marcomanni (ad 172-174); there he wrote the second book  of his Meditations. The camp was finally destroyed by the Germans in the  4th century.</p><p>carob Leguminous evergreen tree ( Ceratonia siliqua) native to the east�  ern Mediterranean region and cultivated elsewhere. It is sometimes known  as locust, or St. John�s bread, in the belief that the �locusts� on which  John the Baptist fed were carob pods. The tree, about 50 ft (15 m) tall,  bears compound, glossy leaves with thick leaflets. Its red flowers are fol�  lowed by flat, leathery pods that contain 5-15 hard brown seeds embed�  ded in a sweet, edible pulp that tastes similar to chocolate.</p><p>carol Popular song, usually of religious joy, associated with a season,  especially Christmas. It typically alternates verses with a repeated refrain  or chorus. The carol originated in medieval England, with texts in English  or Latin or both, and it was often associated with dancing and proces�  sions. The French noel, the German Weihnachtslied, and the Spanish vil-  lancico can also be regarded as carols.</p><p>Carol I Vka-rol ,\ English Vkar-ol \orig. Karl Eitel Friedrich, prince  von Hohenzollern-Sigmaringen (b. April 20, 1839, Sigmaringen,  Hohenzollem-Sigmaringen�d. Oct. 10 1914, Sinaia, Rom.) King of  Romania (1881-1914). Originally a German prince, he became prince of  Romania in 1866, and when Romania gained full independence from the  Ottoman Empire he was crowned its first king. He brought notable mili�  tary and economic development along Western lines, but his neglect of  festering rural problems led to the bloody peasant rebellion of 1907.</p><p>Carol II (b. Oct. 15, 1893, Sinaia, Rom.�d. April 4, 1953, Estoril, Port.)  King of Romania (1930^-0). He became crown prince on the death of his  great uncle, Carol I, in 1914. Because of his scandalous affair with Magda  Lupescu (18967-1977), he was obliged to renounce his rights to the throne  and go into exile in 1925, but he returned in 1930 and became king. He  gradually undermined Romanian democracy and in 1938 proclaimed a  corporatist dictatorship, but in 1940 he was forced to abdicate in favour  of his son Michael.</p><p>Caroline Islands Archipelago, western Pacific Ocean. Lying south of  the Philippines, the islands cover a land area of about 460 sq mi (1,190  sq km). Formerly part of the U.S.-administered Trust Territory of the  Pacific Islands, the group consists of several larger islands, including Yap,</p><p>Pohnpei, Chuuk (Truk), Kosrae, and  Babelthuap, as well as many small  coral islets and reefs. Though  explored by the Spanish in the 16th  century, they were rarely visited until  Germany took them in 1899.  Granted as a mandate to Japan after  World War I, they were placed under  U.S. trusteeship in 1947. The islands  became the Federated States of  Micronesia in 1986, with the excep�  tion of Palau (Babelthuap and asso�  ciated islands), which became  independent in 1994.</p><p>Carolingian V.kar-o-'lin-jonV art  Art produced in Europe during the  reign of Charlemagne and his succes�  sors until c. 900.

Pippin I (d. 640), the dynasty�s  founder, came to power in the office of mayor of the palace under the  Merovingian king Chlotar II, with authority over Austrasia. From this post,  his descendants, including Charles Martel, continued to usurp authority  from the Merovingians, who remained on the throne as figureheads until  751, when Charles�s son Pippin III, with papal support, deposed Childeric  III and formally took the title of King of the Franks. Under Pippin�s son  Charlemagne (Carolus Magnus�the source of the dynasty�s name), the  Carolingian realm was extended into Germany and Italy, where he con�  quered the Lombards and continued the alliance with Rome. Charlemagne  also promoted religious reform and cultural growth and was crowned  emperor by Pope Leo III on Dec. 25, 800. On his death, Charlemagne  was succeeded by his son Louis the Pious, whose three sons divided the  realm in 843. Despite internal strife and foreign invasion, the dynasty sur�  vived until 911 in the eastern part of the realm, where German rulers  would revive Carolingian political ideals later in the century, and in the  western realm until 987.</p><p>Carondelet Vko-.ran-da-'letV (Francisco Luis) Hector, baron de</p><p>(b. c. 1748, Noyelles, Flanders�-d.

When he arrived in New Orleans, he formed alli�  ances with local Indian tribes to defend disputed territory north of the  31st parallel of latitude against U.S. settlers. He negotiated with Gen.  James Wilkinson to effect the secession of the trans-Appalachian territo�  ries from the U.S. and to secure their alliance with Spain. These efforts  were terminated in 1795 with the signing of Pinckney�s Treaty (see Tho�  mas Pinckney). Carondelet was recalled in 1797 and went to South America  to become governor-general of Quito.</p><p>carotene Vkar-3-,ten\ Any of several organic compounds widely dis�  tributed in plants and animals. They are pigments that give orange, yellow,  or sometimes red colours to, for example, dandelions, apricots, carrots,  sweet potatoes, butter, egg yolks, canary feathers, and lobster shells. Car�  otenes are converted in the body into vitamin A, but, unlike the vitamin,  they are not toxic even at high doses. Carotene has an antioxidant effect  and is therefore used in pharmaceuticals and as a food and feed additive,  as well as to colour margarine and butter.</p><p>Carothers Vko-'roth-srzX, W(allace) H(ume) (b.

There  he first worked on polymerization of acetylene and derivatives, leading  to the development of neoprene. His outstanding achievement involved  the theory of linear polymerization; he tested it by synthesizing polymers  structurally resembling cellulose and silk, culminating in the production  of nylon. The first synthetic polymer fibre to be produced commercially  (1938), it laid the foundation of the synthetic fibre industry.</p><p>carp Hardy, greenish brown fish ( Cyprinus carpio, family Cyprinidae)  native to Asia but introduced into Europe, North America, and elsewhere.  Large-scaled, with two barbels (fleshy, whiskerlike feelers) on each side  of its upper jaw, the carp lives alone or in small schools in quiet, weedy,  mud-bottomed ponds, lakes, and rivers. An omnivore, it often stirs up  sediment while rooting about for food, adversely affecting many plants  and animals. Carp grow to an average length of about 14 in. (35 cm);  some grow to 40 in. (100 cm) and 49 lbs (22 kg). In captivity they may  live more than 40 years.</p><p>Carpaccio \kar-'pat-cho\, Vittore (b. c. 1460, Venice�d. 1525/26,  Venice) Italian painter active in Venice. Little is known of his early life,  but the dominant influences on his work were the Bellini family and  Antonello da Messina. In the 1490s he began the first of four cycles of  paintings that are his greatest achievement: scenes from the life of St.  Ursula, now in the Accademia, Venice; scenes from the lives of St.  George, St. Jerome, and St. Tryphon (1502-07) for the Scuola di San  Giorgio degli Schiavoni, Venice; and scenes from the life of the Virgin  (c. 1500-10) and the life of St. Stephen (1511-20). He was one of the  greatest early Renaissance narrative painters of the Venetian school.</p><p>carpal tunnel syndrome (CTS) \'kar-pol\ Painful condition caused  by repetitive stress to the wrist over time.

Repetitive finger and wrist movements rub the ten�  dons against the walls of the carpal tunnel and may make the tendons  swell, squeezing the nerve. Numbness, tingling, and pain in the wrist and  hand may progress to loss of muscle control. CTS is most common in  assembly-line workers and computer keyboard users. Treatment may  include avoidance of the causative activity, ergonomic workplace design,  anti-inflammatory drugs, brace or splint use, and surgery.</p><p>Carpathian Mountains \kar-'pa-the-3n\ Mountain system, eastern  Europe. It extends along the Slovakia-Poland border and southward  through Ukraine and eastern Romania about 900 mi (1,450 km). Its high�  est peak, Gerlachovka (in Slovakia), rises 8,711 ft (2,655 m). The Little  Carpathians and White Carpathians are its southwestern extensions; the  Transylvanian Alps are sometimes called the South Carpathians. The  mountains are the source for the Vistula, Dniester, and Tisza rivers. Agri�  culture, forestry, and tourism are economically important.</p><p>carpel One of the leaflike, seed-bearing structures that constitute the  innermost whorl of a flower. One or more carpels make up the pistil. Fer�  tilization of an egg within a carpel by a pollen grain from another flower  results in SEED development within the carpel.</p><p>Carpentaria \,kar-pen-'tar-e-9\, Gulf of Gulf, northeastern Australia.  An inlet of the Arafura Sea, it is bordered by the Northern Territory and  by Cape York Peninsula and extends north-south about 375 mi (600 km)  and east-west 310 mi (500 km). It was explored by the Dutch 1605-28;  its western coasts were discovered by Abel Janszoon Tasman in 1644.  Neglected for centuries, it became economically significant from the late  20th century for its bauxite and manganese deposits and for its prawn-  rich waters.</p><p>Carpenter Gothic U.S. domestic architecture style of the 19th cen�  tury. The houses executed in this phase of the Gothic Revival style display  little awareness of the original Gothic approach, but rather an eclectic and  naive use of superficial Gothic decorative motifs. Turrets, spires, and  pointed arches were liberally applied, as was much decorative gingerbread,  made possible by the invention of the scroll saw. Carpenter Gothic houses  were built throughout the U.S., but surviving structures are found chiefly  in the Northeast and Midwest.</p><p>Carpentier, Ale jo (b. Dec. 26, 1904, Lausanne, Switz.�d. April 24,  1980, Paris, France) Latin American novelist, essayist, and playwright, a  leading literary figure. Born to a French father and a Russian mother, Car�  pentier spoke French before he learned Spanish, although he was taken  to Havana, Cuba, as an infant. Educated in Havana, he helped found the  Afro-Cuban movement that sought to incorporate African forms into the  arts. He initiated the use of magic realism in his story collection Guerra  del tiempo (1958; War of Time). His best-known novel, Los pasos perdi-  dos (1953; The Lost Steps), portrays a character who travels to the Orinoco  jungle in search of the origins of time. Carpentier fled Cuba in 1928 and  settled in Paris. In 1945 he went to Venezuela, but in 1959 he returned to  Cuba and became a diplomat in Fidel Castro�s regime.</p><p>carpet See rug and carpet</p><p>carpetbagger Epithet used during the Reconstruction period (1865�  77) to describe a Northerner in the South seeking private gain.

Carpocra-  tians revered Jesus as an ordinary man whose soul had not forgotten that  its origin and true home was within the sphere of the unknown perfect  God. They rejected the created world, claimed superiority due to their  ability to communicate with demons, and subverted biblical law as the  work of the evil angels who created the world. Their goal of transcendent  freedom required having every possible experience, which required sev�  eral lifetimes. The first sect known to have used pictures of Christ, they  also made images of Plato, Pythagoras, and Aristotle. See also Gnosticism.</p><p>Carracci \ka-'rat-che\ family Family of Italian painters. Annibale Car�  racci (1560-1609) was prominent in Bologna and Rome in the movement  against Mannerism. In the 1580s, with his brother and cousin, he founded  a teaching academy in Bologna, the Accademia degli Incamminati</p><p>(�Academy of the Progressives�). He specialized in fresco painting and  monumental religious altarpieces but was also a pioneer in the develop�  ment of ideal landscapes, genre subjects, and caricature. The fresco deco�  ration of the Gallery of the Famese Palace in Rome (1597-1601),  comprising scenes from the loves of the gods, remains his masterpiece;  it was indispensable as a source of figure design and technical procedure  for young painters into the 18th century. His elder brother, Agostino Car�  racci (1557-1602), assisted him in decorating the Farnese Gallery but was  known primarily as a teacher and engraver; his anatomical studies were  used as teaching aids for nearly two centuries. His cousin Lodovico (or  Ludovico) Carracci (1555-1619) collaborated with them on various fresco  commissions. He directed the academy in Bologna after his cousins had  gone to Rome, produced works of a passionate and poetic quality, and  trained some of the major Bolognese artists of the next generation, includ�  ing Domenichino, Guido Reni, and Alessandro Algardi.

In 1910 he joined the  struggle of Francisco Madero against  Diaz. A moderate and a nationalist,  he favoured political but not social  reform. Because he did little to  implement the far-reaching reforms  called for in the constitution of 1917,  his presidency was plagued by social  unrest and clashes with the more  radical leaders Pancho Villa and Emil-  iano Zapata as well as by serious  financial problems. His nationalism  led him to oppose U.S. intervention  in Mexican affairs, even when he  stood to benefit from it. He is held  responsible for Zapata�s assassina�  tion and was himself murdered while fleeing an armed rebellion.

His novel Alice�s Adventures in Wonderland  (1865; illustrated by John Tenniel) is based on stories he told to amuse  young friends, especially Alice Liddell. Its sequel, Through the Looking-  Glass (1871), describes Alice�s further adventures. The two books, full of  whimsy but also of sophisticated wit and puzzles, became among the most  famous and admired children�s books in the world. Carroll�s other works  include the narrative nonsense poem The Hunting of the Snark (1876) and  the children�s novels Sylvie and Bruno (1889) and Sylvie and Bruno Con�  cluded (1893).

Cartels can either be domestic (e.g., the historical  example of the German IG Farben) or international (e.g., OPEC). Because  cartels restrict competition and result in higher prices for consumers, they  are outlawed in some countries.

Dec. 11, 1908, New York, N.Y., U.S.)  U.S. composer. Born to a wealthy family, he studied English and music at  Harvard University and later studied in Paris with Nadia Boulanger. He  taught at many institutions, after 1972 primarily at the Juilliard School. He  absorbed a range of influences, including Igor Stravinsky and Charles Ives.  His style evolved into a densely contrapuntal, dissonant, and rhythmically  complex texture in which the various instrumental parts frequently sug�  gest conversation and combat. His principal works include a sonata for  flute, oboe, cello, and harpsichord (1952), Variations for Orchestra  (1955), a double concerto for piano and harpsichord (1961), a piano con�  certo (1965), Concerto for Orchestra (1969), A Symphony of Three  Orchestras (1977), Night Fantasies for piano (1980), and four string quar�  tets (1951, 1959, 1971, 1986), two of which received the Pulitzer Prize. He  is often called the greatest American composer of the late 20th century.</p><p>Carter, Jimmy orig. James Earl Carter (b.

He graduated from  Annapolis and served in the U.S.</p><p>Navy until 1953, when he left to  manage the family peanut business.</p><p>He served in the state senate from  1962 to 1966. He ran unsuccessfully  for governor in 1966; depressed by  this experience, he found solace in  evangelical Christianity, becoming a  born-again Baptist. In 1970 he ran  again and won. As governor (1971�</p><p>75), he opened Georgia�s govern�  ment offices to African Americans  and women and introduced stricter  budgeting procedures for state agencies. In 1976, though lacking a  national political base or major backing, he won the Democratic nomi�  nation and the presidency, defeating the Republican incumbent, Gerald  Ford. As president, Carter helped negotiate a peace treaty between Egypt  and Israel, signed a treaty with Panama to make the Panama Canal a neu�  tral zone after 1999, and established full diplomatic relations with China.  In 1979-80 the Iran hostage crisis became a major political liability. He  responded forcefully to the Soviet Union�s invasion of Afghanistan in  1979, embargoing the shipment of U.S. grain to the Soviet Union and  pressing for a U.S. boycott of the 1980 Summer Olympics in Moscow.  The poor state of the economy, which was plagued by high inflation and  high unemployment, contributed to Carter�s electoral defeat by Ronald  Reagan in 1980. He subsequently became involved in numerous interna�  tional diplomatic negotiations and helped to oversee elections in coun�  tries with insecure democratic traditions; he also became the first sitting  or former American president to visit Fidel Castro�s Cuba. He was  awarded the Nobel Prize for Peace in 2002.</p><p>Carter Family U.S. singing group. It consisted of Alvin Pleasant Carter  (1891-1960), his wife Sara (1898-1979), and his sister-in-law Maybelle  (1909-78). Natives of Virginia, they began their recording career in 1927.  Over 16 years, with various combinations of Carter daughters, they  recorded more than 300 songs from the 19th and early 20th centuries,  including �Wabash Cannonball,� �I�m Thinking Tonight of My Blue  Eyes,� �Wildwood Flower,� and �Keep on the Sunny Side.� They helped  popularize Appalachian folk songs. After the original group broke up in  1943, its members continued to perform. �Mother� Maybelle Carter  formed a successful act with her daughters and later performed with her  son-in-law Johnny Cash. In the 1950s the Carter Family re-formed and  appeared intermittently, with a changing lineup. The original Carter Fam�  ily was the first group admitted (1970) to the Country Music Hall of Fame.</p><p>Carteret \'kart-3-,ret. Sir George (b. c. 1610, probably Jersey, Chan�  nel Islands, Eng.�d. January 1680, New Jersey) British politician and  colonial proprietor. His naval exploits and service as lieutenant governor  of the Channel Island of Jersey won him a knighthood (1644) and bar�  onetcy (1645). After the 1660 Restoration he became a powerful admin�  istrator and legislator. In 1663 he became one of eight original proprietors  granted the area of Carolina; in 1664 he received half of New Jersey,  named for his birthplace. The other owner sold out to the Quakers in 1674.  With the Quakers, Carteret agreed to divide the colony. After Carteret�s  death, his heirs sold the remaining portion to the Quakers.</p><p>Cartesian \,kar-'te-zh3n\ circle Allegedly circular reasoning used by  Rene Descartes to show that whatever he perceives �clearly and distinctly�  is true. Descartes argues that clear and distinct perception is a guarantor  of truth because God, who is not a deceiver, would not allow Descartes  to be mistaken about that which he clearly and distinctly perceives. The  argument relies on Descartes�s earlier proof of the existence of God. But  Descartes cannot know that this proof does not contain an error unless he  assumes that his clear and distinct perception of the steps of his reason�  ing guarantees that the proof is correct. Thus the criterion of clear and  distinct perception depends on the assumption that God exists, which in  turn depends on the criterion of clear and distinct perception. See also  COGITO, ERGO SUM.</p><p>Cartesianism Philosophical tradition derived from the philosophy of  Rene Descartes. A form of rationalism, Cartesianism upholds a metaphysi�  cal dualism of two finite substances, mind and matter. The essence of mind  is thinking; the essence of matter is extension in three dimensions. God  is a third, infinite substance, whose essence is necessary existence. God  unites minds with bodies to create a fourth, compound substance, man.  Mind-body dualism generates problems concerning the possibility of  causal interaction between mind and body and knowledge of the external  world (see mind-body problem ), and various lines of Cartesianism devel�  oped from different proposed solutions to these problems. A historically  important Cartesian theory holds that animals are essentially machines,  lacking even the ability to feel pain.

Located near mod�  ern Tunis, Tun., it was built around a citadel called the Byrsa. Founded by  colonists from Tyre, probably in the 8th century bc, its people undertook  conquests in western Africa, Sicily, and Sardinia in the 6th century bc.  Under the descendants of Hamilcar, it came to dominate the western  Mediterranean Sea. In the 3rd century bc it fought the first of the three  Punic Wars with Rome. Destroyed by a Roman army led by Scipio Afri-  canus the Younger (146 bc), it became the site of a colony founded by  Julius Caesar in 44 bc; in 29 bc Augustus made it the administrative cen�  tre of the province of Africa. Among the Christian bishops who served  there were Tertuluan and St. Cyprian. Captured by the Vandals in 439 and  the Byzantine Empire in the 6th century, it was taken by the Arabs in the  7th century and was eclipsed by their emphasis on Tunis.</p><p>Carthaginian Wars See Punic Wars</p><p>Carthusian \kar-'thii-zh3n\ Member of a Roman Catholic monastic  order founded by St. Bruno of Cologne (c. 1030-1101) in 1084 in the  Chartreuse valley of southeastern France.

He was elected  as a Liberal to the Canadian legislative assembly (1848) and was later  appointed provincial secretary (1855) and attorney general for Canada  East (1857). In 1858 Cartier represented Canada East in the alliance with  Macdonald and promoted the improvement of Anglo-French relations in  Canada. He was a proponent of the Grand Trunk Railway.

His interest in photography developed c. 1930 when he encountered the  works of Eugene Atget and Man Ray. He is known for spontaneous,  sequential images in still photography, a technique inspired by his enthu�  siasm for filmmaking. He helped establish photojournalism as an art form  and with Robert Capa, David Seymour, and others founded the coopera�  tive Magnum Photos (1947).

Political, cultural, or other nongeographic features may be superim�  posed. Ptolemy�s eight-volume Geography showed a flat, disc-shaped pro�  jection of part of the Earth. Medieval European maps followed Ptolemy�s  guide but placed east at the top of the map. In the 14th century more-  accurate maps were developed for use in navigation. The first surviving  globe dates from 1492. Discovery of the New World led to new techniques  in cartography, notably projection of a curved surface onto a flat surface.  In particular, Gerardus Mercator projected landmasses onto a cylinder  wrapped around the Earth�s Equator. Such cylindrical projections main�  tain proper directions or bearings, though they cause distortions in dis�  tances at high latitudes. Contour maps show relief by connecting points of  equal elevation with lines, mean sea level being the reference point. Mod�  ern cartography uses aerial photography and satellite radar for a degree of  accuracy previously unattainable. Satellites have also made possible the  mapping of features of the Moon and of several planets and their moons.  See also geographic information system; global positioning system.</p><p>cartoon Originally, a full-size drawing used for transferring a design to  a painting, tapestry, or other large work. Cartoons were used from the  15th century by fresco painters and stained-glass artists. In the 19th cen�  tury the term acquired its popular meaning of a humorous drawing or  parody. Cartoons in that sense are used today to convey political com�  mentary, editorial opinion, and social comedy in newspapers and maga�  zines. The greatest early figure is William Hogarth, in 18th-century Britain.</p><p>In 19th-century France, Honore Daumier introduced accompanying text  that conveyed his characters� unspoken thoughts. Britain�s Punch became  the foremost 19th-century venue for cartoons; in the 20th century The New  Yorker set the American standard.

Cartwright was a founder of the amateur New York Knicker�  bocker Base Ball Club and chaired the commission that established base�  ball�s official rules. These included the requirement of tagging out a base  runner rather than hitting him with a thrown ball and fixing the distance  between bases at 90 ft (27.4 m). The first game under the newly codified  rules was apparently played in Hoboken, N.J., in 1846. See also Abner  Doubleday.</p><p>Cartwright, Edmund (b.

On visiting  Richard Arkwright�s cotton-spinning mills, he was inspired to construct a  power-driven machine for weaving. He invented a power loom and set up  a weaving and spinning factory in Yorkshire. In 1789 he patented a wool-  combing machine. In 1809 the House of Commons voted to reward him  for the benefits his loom had conferred on the nation. His other inventions  included a cordelier (machine for making rope) and a steam engine that  used alcohol instead of water.</p><p>Caruso \k3-'ru-so\, Enrico orig. Errico Caruso (b.

He attracted the notice of a teacher and made his professional debut  in 1894. He sang his best-known role, Canio in Ruggero Leoncavallo�s  Pagliacci, for the first time in 1896. He recovered from a disastrous La  Scala debut in 1900 and within two years had gained the high notes that  made him an international star and a legend. He sang at the Metropolitan  Opera (1903-20) in almost 60 roles, becoming the most famous male  opera star of his time. His warm, appealing tenor voice of great emotive  power made his recordings (which include some of the first vocal record�  ings ever made) best-sellers for decades after his death.</p><p>Carver, George Washington (b</p><p>U.S.�d.

In 1896 he joined Booker T.</p><p>Washington at the Tuskegee Institute  (now Tuskegee University) in Alabama,  where he became director of agricul�  tural research. He was soon promot�  ing the planting of peanuts and  soybeans, legumes that he knew  would help restore the fertility of soil  depleted by cotton cropping. To  make them profitable, he worked  intensively with the sweet potato and  the peanut (then not even recognized  as a crop), ultimately developing 118  derivative products from sweet pota�  toes and 300 from peanuts. His efforts helped liberate the South from its  untenable cotton dependency; by 1940 the peanut was the South�s sec�  ond largest cash crop. During World War II he devised 500 dyes to replace  those no longer available from Europe. Despite international acclaim and  extraordinary job offers, he remained at Tuskegee throughout his life,  donating his life�s savings in 1940 to establish the Carver Research Foun�  dation at Tuskegee.</p><p>Carver, Jonathan (b.

The fibre became known for its use in beautiful shawls and other  handmade items produced in Kashmir, India. The fibres have diameters  finer than those of the best wools. Natural colour is usually gray or tan  but ranges from white to black. Cashmere fabric is warm and comfort�  able and has excellent draping qualities and soft texture; it is used mainly  for fine coat, dress, and suit fabrics and for high-quality knitwear and  hosiery. A sweater requires the fleece of 4-6 goats; an overcoat uses that  of 30-40. Because world production is small and gathering and process�  ing are costly, cashmere is a luxury fibre.</p><p>Casimir Vka-zs-.mirX III known as Casimir the Great Polish  Kazimierz Weilki (b. April 30, 1310, Kujavia, Pol.�d. Nov. 5, 1370)  King of Poland (1333-70). He was the son of Wladyslaw I, who revived  the Polish kingship, and he continued his father�s quest to make Poland  a power in central Europe. He crafted treaties with Hungary, Bohemia,  and the Teutonic Order and acquired Red Russia and Masovia by diplo�  macy. Casimir also arranged a series of dynastic alliances that tied Poland  to many royal European families. He codified Teutonic law, gave new  towns self-government under the Magdeburg Law, and founded the Uni�  versity of Krakow.</p><p>Casimir IV known as Casimir Jagiellonian \yag-yel-'lo-ne-3n\ Pol�  ish Kazimierz Jagiellonczyk (b. Nov. 30, 1427�d. June 7, 1492)  Grand duke of Lithuania (1440-92) and king of Poland (1447-92). He  became ruler of Lithuania by will of the boyars and king of Poland on  his brother�s death. He sought to preserve the political union between  Poland and Lithuania and to recover the lost lands of old Poland. Through  his own marriage to Elizabeth of Habsburg and the marriages of his chil�  dren, he formed alliances with various European royal houses and built  the Jagiellon dynasty. The great triumph of his reign was the effective  destruction of the Teutonic Order (1466), which brought Prussia under  Polish rule.</p><p>casino Building or room used for gambling. The term originally referred  to a public hall for music and dancing, but by the late 19th century it had  come to denote a gaming house, particularly one in which card and dice  games were played. Today casinos are places where gamblers can risk  their money against a common gambler (called the banker or house), and  they have an almost uniform character throughout the world. One of the  oldest and best-known casinos is that at Monte Carlo (Monaco), founded  in 1861. Others include those at Cannes and Nice (France), Corfu  (Greece), Baden-Baden (Germany), Rio de Janeiro (Brazil), and Las  Vegas and Reno (Nevada, U.S.). Casinos in Havana (Cuba) were confis�  cated by the Castro government after the 1959 revolution, spelling the  end of a flourishing gambling scene that rivaled Las Vegas. Nevada has  long had casino gambling, but other U.S. states prohibited it; that ban was  ended when a casino opened in Atlantic City, N.J., in 1978. From the  1980s casinos began appearing on American Indian reservations, which  are not subject to state antigambling statutes, and casino gambling  expanded vastly in the U.S. as gambling became legal in more states, par�  ticularly as a riverboat operation. In the late 1990s Internet gambling sites  permitted players to play casino games such as roulette and blackjack.  These virtual casinos usually offered the option of playing against other  players or only against the house.</p><p>Casper City (pop., 2000: 49,644), east-central Wyoming, U.S., on the  North Platte River. Founded in 1888, it was located on the Oregon Trail  and the Pony Express route. The discovery of oil in the 1890s began an oil  boom, and the oil fields of the Teapot Dome scandal were nearby. Casper�s  economy is based on the production of oil and natural gas and the manu�  facture of oil-field equipment. Mining (uranium, coal, bentonite) and  cattle and sheep raising also are important.</p><p>Caspersson \kas-'per-,s6n\, Torborn Oskar (b. Oct. 15, 1910, Mot-  ala, Swed.) Swedish cell biologist and geneticist. After receiving his medi�  cal degree from the University of Stockholm in 1936, he initiated the use  of the ultraviolet microscope to determine the nucleic acid content of cel�  lular structures such as the nucleus and nucleolus. He theorized that  nucleic acids must be present for protein synthesis to occur. He was the</p><p>first to perform cellular chemical studies on the giant chromosomes found  in insect larvae. He also investigated the role of the nucleolus in protein  synthesis.</p><p>Caspian Sea Inland salt lake between Europe and Asia, bordering  Azerbaijan, Russia, Kazakhstan, and Iran. With a basin 750 mi (1,200 km)  long and up to 200 mi (320 km) wide and an area of 149,200 sq mi  (386,400 sq km), it is the largest inland body of water in the world.  Though it receives many rivers, including the Volga, Ural, and Kura, the  sea itself has no outlet. It was important as a commercial route in the  premodern era, when it formed part of the Mongol-Baltic trade route for  goods from Asia. It is now a major source of petroleum. Its numerous  ports include Baku in Azerbaijan and Bandar-e Anzall and Bandar-e Torka-  man in Iran.</p><p>Cass, Lewis (b. Oct. 9, 1782, Exeter, N.H., U.S.�d. June 17, 1866,  Detroit, Mich.) U.S. politician. He fought in the War of 1812 and served  as governor of Michigan Territory (1813-31). As secretary of war (1831-  36) under Pres. Andrew Jackson, he directed the conduct of the Black  Hawk and Seminole wars. He served as U.S. minister to France (1836�  42). In the U.S. Senate (1845^18, 1849-57), he supported westward  expansion and the Compromise of 1850. He was the Democratic nominee  in the presidential election of 1848, which he lost to Zachary Taylor. He  later served as secretary of state (1857-60) but resigned when Pres. James  Buchanan took no action to counter the secession of the Southern states.</p><p>Cassandra In Greek mythology, the daughter of King Priam of Troy.  Apollo promised her the gift of prophecy if she would grant his desires;  she accepted the gift but rebuffed the god, who took his revenge by  ordaining that her prophecies should never be believed.

June 14, 1926, Chateau de Beaufresne, near Paris, France) U.S.  painter and printmaker, active in Paris. She spent her early years travel�  ing in Europe with her wealthy family. After attending the Pennsylvania  Academy of the Fine Arts (1860-65) she later studied in Paris, copying  Old Masters. In 1874 Cassatt chose Paris as her permanent residence and  established her studio there. She shared with the Impressionists an inter�  est in experiment and in the use of bright colours inspired by the out-of-  doors. Edgar Degas became her friend, and at his request she exhibited  with the Impressionists. She portrayed scenes of everyday life, particu�  larly images of mothers and children, and was skilled at drawing and  printmaking. Some of her best works were executed in pastel. Through  her social contacts with wealthy private collectors, she promoted Impres�  sionism in the U.S. and exerted a lasting influence on U.S. taste.</p><p>cassava \k3-'sa-v3\ or manioc or yuca Tuberous edible perennial  plant (. Manihot esculenta ) of the spurge family, from the New World trop�  ics. It is cultivated for its tuberous roots, from which cassava flour, breads,  tapioca, a laundry starch, and an alcoholic beverage are derived. It has  conspicuous, almost palmate (fan-shaped) leaves and fleshy roots. Dif�  ferent varieties range from low herbs through many-branched shrubs to  slender, unbranched trees adapted to diverse habitats.</p><p>Cassavetes X.ka-so-'ve-tezV John (b.

He acted in films and in television dramas before making his directorial  debut with the critically praised Shadows (1961), a low-budget indepen�  dent film in the cinema verite style. He played featured roles in such films  as The Dirty Dozen (1967) and Rosemary�s Baby (1968) and returned to  directing independent films, including Faces (1968), Husbands (1970),  and A Woman Under the Influence (1974), which dramatized marital prob�  lems.</p><p>cassia \'ka-sha\ Spice, also called Chinese cinnamon, consisting of the  aromatic bark of the Cinnamomum cassia plant, of the laurel family. Simi�  lar to true cinnamon bark, cassia bark has a more pungent, less delicate  flavor and is thicker. It is used as a flavoring in cooking. Whole buds, the  dried, unripe fruits of C. cassia and C. loureirii , taste like the bark and  are added to foods for flavoring. Confusion sometimes arises with another  group of plants because Cassia is the name of an extensive genus of  legumes, the source of various medicinal products and of senna leaves.</p><p>Cassidy, Butch orig.

Taking his name from an older outlaw mentor, Cassidy  was a cattle rustler and a robber from the mid-1880s. In 1900 he became  the criminal partner of Harry Longabaugh, the �Sundance Kid� (1870-  1909?), whose nickname derived from a town where he had once been  imprisoned. They became the foremost members of the Wild Bunch, a  group of bank and train robbers. The two eluded Pinkerton detectives by  escaping to South America in 1901. They bought a ranch in Argentina but  returned to a life of outlawry in 1906. In 1909, trapped by soldiers in  Bolivia, Sundance was mortally wounded, and Cassidy shot himself. The  time, place, and circumstances of their deaths vary widely in different  accounts.</p><p>Cassini, Gian Domenico (b. June 8, 1625, Perinaldo, Republic of  Genoa�d. Sept. 14, 1712, Paris, France) Italian-born French astronomer.  His early studies were mainly observations of the Sun, but, after obtain�  ing more powerful telescopes, he turned his attention to the planets. He  calculated Jupiter�s and Mars�s rotational periods and compiled a table of  the positions of Jupiter�s satellites. His observations of the Moon (1671�  79) led to his compiling a large map. In 1683, after a study of the zodia�  cal light, he concluded it was of cosmic origin. He discovered four of  Saturn�s moons: Iapetus (1671), Rhea (1672), Tethys (1684), and Dione  (1684). The dark gap between two of Saturn�s main rings (Cassini�s divi�  sion) is named for him.</p><p>Cassiodorus \,ka-se-o- l dor-os\ in full Flavius Magnus Aurelius  Cassiodorus (b. 490, Scylletium, Bruttium, kingdom of the  Ostrogoths�d. c. 585, Vivarium Monastery, near Scylletium) Historian,  statesman, and monk who helped preserve Roman culture after the col�  lapse of the Roman Empire. He was secretary to Theodoric and later held  other high imperial offices. Soon after 540 he founded a monastery to per�  petuate the culture of Rome. He collected pagan and Christian manu�  scripts and had the monks copy them, establishing a practice continued  in later centuries. His own works included the Chronicon, a history of  mankind to 519; De anima, on the soul after death; and Institutiones div-  inarum et saecularium litterarum, on the study of scripture and the seven  liberal arts.</p><p>Cassirer \ka-'sir-9r\, Ernst (b. July 28, 1874, Breslau, Silesia, Ger.�d.  April 13, 1945, New York, N.Y., U.S.) German philosopher and educa�  tor. He taught at the University of Berlin (1905-19) and the University  of Hamburg (1919-33) before the rise of Nazism forced him to flee to  Sweden and the U.S. Cassirer�s philosophy, based primarily on the work  of Immanuel Kant, expanded that philosopher�s doctrines concerning the  ways in which human experience is structured by innately existing con�  cepts. After examining various forms of cultural expression, Cassirer con�  cluded that man is uniquely characterized by his ability to use the  �symbolic forms� of myth, language, and science to structure his expe�  rience and thereby to understand both himself and the natural world. His  most important original work is The Philosophy of Symbolic Forms  (1923-29); he also wrote works on Kant, G.W. Leibniz, Renaissance cos�  mology, and the Cambridge Platonists.</p><p>Cassius \'kash-os\ (Longinus), Gaius (d. 42 bc, near Philippi, Mace�  donia) Roman general and administrator. He fought alongside Pompey the  Great against Julius Caesar but was reconciled with Caesar after Pompey�s  defeat. Motivated by jealousy and bitterness, he joined Brutus in the suc�  cessful conspiracy to assassinate Caesar (44 bc). Forced to leave Rome  after the assassination, he went to Syria, and there he ousted the Roman  governor (43). With Brutus he raised an army in Macedonia to challenge  the Second Triumvirate. Defeated at the Battle of Philippi by Mark Antony,  he had his freedmen slay him. He was lamented by Brutus as �the last of  the Romans.�</p><p>cassone \ko-'so-na\ or marriage chest Chest, usually of wood,  intended to contain a bride�s dowry or to be given as a wedding present.  It was the most elaborately decorated piece of furniture in Renaissance  Italy. In the 15th century, wealthy Florentine families employed artists  such as Sandro Botticelli and Paolo Uccello to decorate cassoni with paint�  ings. They were often made in pairs, bearing the respective coats of arms  of the bride and groom. Though cassoni were made in many countries,  the finest come from Italy.</p><p>cassowary \'ka-S9-,wer-e\ Any of several species of rattle (family  Casuariidae) of the Australo-Papuan region. Related to the emu, it has been  known to kill humans with slashing blows of its feet, which have long,  daggerlike claws on the innermost toe. It has a featherless blue head pro�  tected by a bony crest and has a black body (immature birds are brown�</p><p>ish). It moves rapidly along narrow  tracks in the bush. Cassowaries eat  fruit and small animals. The largest  species is the common, or southern,  cassowary ( Casuarius casuarius),  which stands almost 5 ft (1.5 m) tall.</p><p>cast iron Alloy of iron that con�  tains 2-4% carbon, along with sili�  con, manganese, and impurities. It is  made by reducing iron ore in a blast  furnace (cast iron is chemically the  same as blast-furnace iron) and cast�  ing the liquid iron into INGOTS called  pigs. Pig iron is remelted, along with  scrap and alloying elements, in  cupola furnaces and recast into  molds for a variety of products. In  the 18th�19th centuries, cast iron  was a cheaper engineering material  than wrought iron (not requiring  intensive refining and hammering). It  is more brittle and lacks tensile  strength. Its compressive (load-  bearing) strength made it the first  important structural metal. In the  20th century, steel replaced it as a  construction material, but cast iron still has industrial applications in auto�  mobile engine blocks, agricultural and machine parts, pipes, hollowware,  stoves, and furnaces. Most cast iron is either so-called gray iron or white  iron, the colours shown by fracture; gray iron contains more silicon and  is less hard and more machinable than white iron. Both are brittle, but  malleable cast iron (produced by prolonged heat-treating), first made in  18th-century France, was developed into an industrial product in the U.S.  Cast iron that is ductile as cast was invented in 1948. The latter now con�  stitutes a major family of metals, widely used for gears, dies, automobile  crankshafts, and many other machine parts.</p><p>Castagno \ka-'sta-nyo\, Andrea del orig. Andrea di Bartolo (b.</p><p>c. 1421, San Martino a Corella, Republic of Florence�d. Aug. 19, 1457,  Florence) Italian painter active in Florence. Little is known of his early  life, and many of his paintings have been lost. His earliest dated works  are frescoes in the church of San Zaccaria in Venice (1442). In 1447 he  began his greatest work, a series of monumental frescoes depicting the  Last Supper and other scenes of Christ�s Passion for the convent of Sant�  Apollonia in Florence (now a museum). His use of pictorial illusionism  and scientific perspective, as well as the powerful, sculptural form of his  figures, established him as one of the most influential Renaissance paint�  ers of the 15th century.</p><p>caste Any of the ranked, hereditary, endogamous (see exogamy and  endogamy) occupational groups that constitute traditional societies in cer�  tain regions of the world, particularly among Hindus in India. There caste  is rooted in antiquity and specifies the rules and restrictions governing  social intercourse and activity. Each caste has its own customs that restrict  the occupations and dietary habits of its members and their social con�  tact with other castes. There are about 3,000 castes, or jatis (broadly,  �form of existence fixed by birth�), and more than 25,000 subcastes in  India. They are traditionally grouped into four major classes, or varnas  (�colours�). At the top are the Brahmans, followed by the Kshatriyas, Vaish-  yas, and Shudras. Those with the most defiling jobs (such as those who  dispose of body emissions and dead animals) are ranked beneath the Shu�  dras. Considered untouchable, they were simply dubbed as �the fifth�  (panchama ) category. Although a great many spheres of life in modem  India are little influenced by caste, most marriages are nevertheless  arranged within the caste. This is in part because most people live in rural  communities and because the arrangement of marriages is a family activ�  ity carried out through existing networks of kinship and caste.</p><p>caste \'kast\ In biology, a subset of individuals within a colony of social  animals (chiefly ants, bees, termites, and wasps) that has a specialized func�  tion and is distinguished from other subsets by morphological and ana�  tomical differences.

While imprisoned for eloping with another man�s wife, he wrote his best-  known work, Amor de perdigao (1862; �Fatal Love�), about a thwarted  love that leads to crime and exile. His 58 novels, many mirroring his pas�  sionate life, range from Romantic melodrama to realism. His best works  include O romance d�um homem rico (1861; �The Love Story of a Rich  Man�) and O retrato de Ricardina (1868; �Portrait of Ricardina�).

He is remembered for  The Courtier (1528). Written in the  form of a philosophical dialogue, it  describes the conduct of the perfect  courtier, the qualities of a noble lady,  and the ideal relationships between  the courtier and his prince. Immedi�  ately successful in Italy and beyond,  it became a manual for those aspir�  ing to aristocratic manners during  the Renaissance.</p><p>Castile \ka-'stel\ Spanish Castilla  \ka-'ste-lya\ Traditional region, pen�  insular Spain. Comprising several  modern provinces, its northern part is  called Old Castile and its southern  part New Castile. Castilian territory was united under Leon by Feman  Gonzalez in the 10th century. Though it separated from Leon in the 12th  century, it was reunited with it by Ferdinand III in 1230. The Spanish part  of the kingdom of Navarra was annexed by Castile in 1512, thus complet�  ing the formation of modern Spain. Castile remains Spain�s centre of politi�  cal and administrative power.

Though blind from  childhood, he became a classical scholar and by age 16 was publishing  poems, translations, and pedagogical works. With his Obras completas  (1837; �Complete Works�), he became a literary figure in Lisbon. As  director of the important journal O panorama and later of the major cul�  tural review Revista universal Lisbonense, he became a central figure in  the Portuguese Romantic movement. After 1850 he gradually returned to  a genteel traditionalism. His lifeless style so dominated literary taste that  it provoked a rebellion by younger writers, and he was dethroned as lit�  erary arbiter.</p><p>Castillo de San Marcos \ka-'ste-yo-da-san-'mar-kos\ National  Monument Historic site, northeastern Florida, U.S. Established in  1924, it is the 25-acre (10-hectare) site of the oldest masonry fort in the  U.S., built by the Spanish (1672-95) to protect St. Augustine.

In the 19th century it served as a U.S. military prison.</p><p>casting Pouring of molten metal into a mold, where it solidifies into the  shape of the mold. The process was well established in the Bronze Age,  when it was used to form bronze pieces now found in museums. It is par�  ticularly valuable for the economical production of complex shapes, rang�  ing from mass-produced parts for automobiles to one-of-a-kind  production of statues, jewelry, or massive machinery. Most steel and iron  castings (see cast iron) are poured into silica sand. For metals of lower  melting point, such as aluminum or zinc, molds can be made of another  metal or of sand.

The castle developed  rapidly in western Europe from the 9th century. In form it was somewhat  sprawling compared to later fortified buildings. The castle�s enceinte  (outer wall) was surrounded by one or more moats, which were crossed  by drawbridges that could be raised from the inner side. The gateway itself  was heavily protected and often defended by a barbican, or watchtower.  One or more baileys, or walled courtyards, surrounded the donjon.

The illegal and inhumane  practice of castration, largely practiced in Italy, could produce a treble  voice of extraordinary power, attributable to the lung capacity and physi�  cal bulk of the adult male. The unique tone quality and the ability of  intensively trained singers to execute virtuosic passagework made cast-  rati the rage among opera audiences and contributed to the spread of Ital�  ian opera. Most male singers in 18th-century opera were castrati; the most  famous bore the stage names Senesino (Francesco Bemardi; died c. 1750),  Caffarelli (Gaetano Majorano; 1710-1783), and Farinelli. Castrati sang in  the Sistine Chapel choir until 1903.</p><p>Castries \ka-'stre, 'kas-,tre\ Seaport (pop., 1997 est.: 16,187), capital of  Saint Lucia. Located on the island�s northwestern coast, its fine harbour is  Saint Lucia�s chief port. A fortress on Mount Fortune (852 ft [260 m])  overlooks the town. Castries is a gateway for tourists visiting the island.</p><p>Castro (Ruz), Fidel (b. Aug. 13, 1926/27, near Biran, Cuba) Political  leader of Cuba (from 1959). Son of a prosperous sugar planter, he became  a lawyer and worked on behalf of the poor in Havana. He was a candi�  date for Cuba�s legislature when Gen. Fulgencio Batista overthrew the  government in 1952. He organized a rebellion against Batista in 1953, but  it failed; captured, he served time in prison and then went to Mexico,  where he and others, including Che Guevara, continued to plot Batista�s  overthrow. Castro led an armed expedition back to Cuba in 1956; most  of his men were killed, but a dozen survivors took refuge in the moun�  tains, where they gradually managed to organize guerrillas throughout the  island. In 1959 Batista was forced to flee the country. Castro nationalized  private commerce and industry and expropriated U.S.-owned land and  businesses, vastly expanded health services and eliminated illiteracy, and  ruthlessly suppressed opposition, outlawing all political groups but the  Communist Party. The U.S. attempted to bring about his overthrow and  failed (see Bay of Pigs invasion), precipitating the Cuban missile crisis. Cas�  tro exercised total control of the government and economy, which was  increasingly dependent on subsidies from the Soviet Union. The Soviet  Union�s collapse (1991) devastated Cuba�s economy, and Castro has  attempted to replace its former revenues by encouraging tourism.</p><p>Castro y Bellvis Vkas-tro-e-beP-'vesX, Guillen de (b. 1569, Valen�  cia, Spain�d. 1631, Madrid) Spanish playwright. Of his approximately  50 plays, the best-remembered is The Youth of the Cid (c. 1599), on which  Pierre Corneille based his Le Cid (1637). Castro�s play is notable for its  naturalistic dialogue. He was one of the earliest playwrights to deal with  the difficulties of marriage, as in The Unhappy Marriages of Valencia. He  drew heavily on traditional Castilian ballads and based three of his plays  on novels by Miguel de Cervantes.</p><p>casualty insurance Provision against loss to persons and property,  covering legal hazards as well as those of accident and sickness. Major  classes include liability, theft, aviation, workers' compensation, credit, and  title. Liability insurance contracts may cover liability arising from use of  an automobile, operation of a business, professional negligence (malprac�  tice insurance), or property ownership. Credit insurance may cover the risk  of bad debts from insolvency, death, and disability, the risk of loss of sav�  ings from bank failure, and the risk of loss of export credit due to com�  mercial or political changes.</p><p>casuarina \,kazh-y3-'re-n9\ Any of the chiefly Australian trees that  make up the genus Casuarina (family Casuarinaceae), which have whorls  of scalelike leaves and segmented stems resembling horsetails. Several  species, especially C. equisetifolia, are valued for their hard, dense, yel�  lowish to reddish brown wood, which is strong and reputed to be resis�</p><p>tant to termite attack. Beefwood and ironwood are common names that  reflect the wood�s colour and hardness.</p><p>cat or feline Any member of the family Felidae, the most highly spe�  cialized group of mammalian carnivores. Modern-type cats appeared in  the fossil record about 10 million years ago. Cats in the genus Panthera  (leopard, jaguar, tiger, and lion) roar but cannot purr, and their pupils are  round. Other cats, including the snow leopard and cougar, can purr but  do not roar; the pupil is usually vertical. Cats have sharp, retractable  (except in the cheetah) claws, and their teeth are adapted for stabbing,  anchoring, and cutting. They almost always land on their feet when they  fall from a height. Most species are nocturnal, and their eyes are adapted  for seeing in low light. Cats are known for their habit of grooming them�  selves with their rasplike tongue. Small cats have been domesticated for  some 3,500 years (see domestic cat). Other cat species include the bobcat,  CARACAL, LYNX, OCELOT, SERVAL, and WILDCAT.</p><p>CAT See computed axial tomography  cat bear See lesser panda</p><p>catacomb Subterranean cemetery of galleries with recesses for tombs.  The term was probably first applied to the cemetery under St. Sebastian�s  Basilica that was a temporary resting place for the bodies of Sts. Peter and  Paul in the late 3rd century ad, but it came to refer to all the subterranean  cemeteries around Rome. In addition to serving as burial sites, catacombs  in early Christian Rome were the sites of funeral feasts celebrated in fam�  ily vaults on the day of burial and on anniversaries. They were used as  hiding places during times of persecution; Pope Sixtus II was supposedly  captured and killed (ad 258) while hiding in the St. Sebastian�s catacomb  during Valerian�s persecution. Catacombs are also found in Sicily and  other parts of Italy, in Egypt, and in Lebanon.</p><p>Arched niche of a tomb with early Christian paintings of scenes from the Old and  New Testaments, in the catacomb on Via Latina, Rome</p><p>PONT.

GRIMOLDI</p><p>Catalan Vka-t3-,lan\ language Romance language spoken in eastern  and northeastern Spain, chiefly Catalonia and Valencia, and in Andorra,  the Balearic Isles, and the Roussillon region of France. Its literary tradi�  tion dates from the 12th century, when it was the official language of the  kingdom of Aragon. As Catalonia achieved greater autonomy in the late  20th century, Catalan revived as the language of politics and education  there. Its dialects, divided into an Occidental and an Oriental group,  remain mutually intelligible. Catalan is related to the Occitan language of  southern France and to Spanish.</p><p>Catalhuyuk Vcha-.tal-hiE-'yuikA English foha-.tal-hii-'yukX Neolithic  site, Anatolia. Located near Konya in southern Turkey, it was the centre  of an advanced Neolithic culture. The earliest period of settlement is ten�  tatively dated to c. 6700 bc and the latest to c. 5650 bc. Excavation of the  religious quarter produced a series of shrines; the wall paintings have been  linked with Upper Paleolithic art.</p><p>Catalonia Catalan Catalunya Spanish Cataluna Autonomous  community (pop., 2001: 6,343,110) and historic region, northeastern</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>350 I catalpa &#x25BA; catbird</p><p>Spain. It encompasses the provinces of Girona, Barcelona, Tarragona, and  Lleida and covers an area of 12,399 sq mi (32,113 sq km). Its capital is  Barcelona. The Pyrenees separate Catalonia from France; the Mediterra�  nean Sea lies to the east. Its principal rivers, the Ter, Llobregat, and Ebro,  all run into the Mediterranean. Catalonia was one of Rome�s first Span�  ish possessions. Occupied in the 5th century ad by the Goths, it was taken  by the Moors in 712 and by Charlemagne in 795. After the unification of  Spain (1469), Catalonia lost its centrality in Spanish affairs, and by the  17th century its conflict of interest with Castile-Leon led to the first of a  series of separatist movements. Catalan nationalism became a serious  force after 1876. In 1932 a compromise with the central government  granted Catalonia autonomy; this was revoked with the 1939 Nationalist  victory in the Spanish Civil War, and Francisco Franco�s government  adopted a repressive policy toward Catalan nationalism. The reestablish�  ment of democratic rule after Franco�s death again led to autonomy in  1979. Today it is the richest and most industrialized part of Spain.</p><p>catalpa Xko-'tal-psX Any of 11 species of trees in the genus Catalpa  (family Bignoniaceae), native to eastern Asia, eastern North America, and  the West Indies. Catalpas have large, attractive leaves and showy white,  yellowish, or purplish flowers. The catalpa fruit is a long cylindrical pod  bearing numerous seeds with white tufts of hair at each end. The com�  mon catalpa, C. bignonioides, yields a durable timber and is one of the  most widely planted ornamental species.</p><p>catalysis \ko-'ta-b-s3s\ Modification (usually acceleration) of a chemi�  cal reaction rate by addition of a catalyst, which combines with the reac�  tants but is ultimately regenerated so that its amount remains unchanged  and the chemical equilibrium of the conditions of the reaction is not altered.  Catalysts reduce the activation energy barrier between reactants and prod�  ucts. When more than one reaction is possible, a catalyst that accelerates  only one reaction pathway selectively enhances the creation of its prod�  uct. Catalysis is inhibited if the reactant or the catalyst is removed or  altered by any of several types of agents (inhibitors). Catalysis in a single  phase (e.g., the catalyst is dispersed in a liquid solution or gaseous mix�  ture with the reactants) is homogeneous; that in more than one phase (e.g.,  the reactants are liquids and the catalyst a solid) is heterogeneous. Chemi�  sorption, a type of heterogeneous catalysis, often involves bonding  between the catalyst�s solid surface and the reactant, changing the nature  of the chemisorbed molecules. To make the accessible surface area as  large as possible, such catalysts are finely powdered or highly porous sol�  ids. Catalysis is essential to the modern chemical industry. See also enzyme.</p><p>catalyst \'ka-t 3 l-3st\ Any substance of which a small proportion nota�  bly affects the reaction rate of a chemical reaction without itself being  changed or consumed (see catalysis). One molecule may transform sev�  eral million reactant molecules a minute. Catalysts may be gaseous, liq�  uid, or solid; they may be inorganic compounds, organic compounds, or  complex combinations. They tend to be highly specific, reacting with only  one substance or a small set of substances. Substances that reduce the  effectiveness of catalysts by altering them or blocking reactants� access  to them are called catalyst inhibitors or catalyst poisons. Catalysts are  essential to virtually all industrial chemical reactions, especially in petro�  leum refining and synthetic organic chemical manufacturing. Most solid  catalysts are transition elements (metals) or their oxides in finely divided  or porous form. In a car�s catalytic converter, the platinum catalyst con�  verts unburned hydrocarbons and nitrogen compounds to products less  harmful to the environment. Water, especially saltwater, catalyzes oxida�  tion (see oxidation-reduction) and corrosion. Enzymes are among the most  active and selective catalysts known.</p><p>catalytic converter In automobiles, a component of emission control  systems used to reduce the discharge of noxious gases from the internal-  combustion engine. The catalytic converter consists of an insulated cham�  ber containing pellets of catalyst through which the exhaust gases are  passed. The exhaust�s hydrocarbons and carbon monoxide are converted to  water vapour and carbon dioxide.</p><p>catamaran Vka-to-mo-.ranV Twin-hulled sailing and engine-powered  boat. Its design was based on a raft of two logs bridged by planks used  by peoples in the Indonesian archipelago, Polynesia, and Micronesia. Up  to 70 ft (21 m) long, early catamarans were paddled by many men and  used for travel, in war, and in recreation. Especially after the sail was  added, voyages as long as 2,000 mi (3,700 km) were made. In the 1870s  they sailed so successfully against monohulled boats that they were barred</p><p>from racing. The modern catamaran, which averages about 40 ft (12 m)  in length, has been produced since 1950. They are very fast craft, achiev�  ing speeds of 20 mph (32 kph).</p><p>Catania \ka-'ta-nya\ City (pop., 2001 prelim.: 306,464), Sicily, Italy. It  was founded by Greeks in 729 bc at the foot of Mount Etna on the Gulf  of Catania. Taken by the Romans in the First Punic War (263 bc), Cata�  nia was made a Roman colony by Octavian (later Augustus). Catanian  Christians suffered under the emperors Decius and Diocletian; their mar�  tyrs included St. Agatha, patron saint of the city. Catania fell successively  to the Byzantines, Arabs, and Normans, and it suffered devastation by  earthquakes especially in 1169 and 1693. In World War II the city was  severely damaged by bombing. Rebuilt, it is Sicily�s second largest city  and is an industrial and transportation centre.</p><p>Catanzaro \,ka-tand-'za-r6\ City (pop., 2001 prelim.: 93,540), capital  of Calabria, southern Italy. Catanzaro lies near the Gulf of Squillace. It  was probably founded in the 10th century by Byzantines. It was taken in  1059 by the Normans under Robert Guiscard. It played an important part  in the Napoleonic Wars and in the movement for Italian unity. Catanzaro  suffered severely from earthquakes in 1905 and 1907 and from bombing  in World War II. It is an agricultural centre.</p><p>catapult Mechanism for forcefully propelling stones, spears, or other  projectiles, in use since ancient times. Nearly all catapults employed in  ancient and medieval artillery operated by a sudden release of tension on  wooden beams or twisted cords of horsehair, gut, sinew, or other fibres.  An exception was the medieval trebuchet, powered by a counterweight.  Modem mechanisms using steam, hydraulic pressure, tension, or other  force to launch gliders, aircraft, or missiles are also called catapults.</p><p>cataract Opacity of the eye�s crystalline lens. Cataracts causing central  visual-field defects are most likely to affect vision. Cataracts may occur in  newborns and infants. Diabetes mellitus, prolonged exposure to ultravio�  let rays, or trauma can cause them in adults, but they most often occur  with age, resulting from gradual loss of transparency of the lens. Treat�  ment is a surgical procedure to replace the lens with an artificial one.</p><p>catastrophe theory Branch of mathematics (considered a branch of  geometry) that explores how gradual changes to a system produce sud�  den, drastic results (though usually not as dire as the name suggests). A  simple example is how a plastic coffee stirrer subjected to gradually  increasing pressure from both ends will suddenly buckle in one direction  or another. Other �catastrophes� include optical phenomena such as  reflection or refraction of light through moving water. More speculatively,  ideas from catastrophe theory have been applied by social scientists to  such situations as the sudden eruption of mob violence.</p><p>Catatumbo \,ka-ta-'tum-bo\ River River, northern South America.  Rising in northern Colombia, it flows northeast across the Venezuelan  border and the oil-rich Maracaibo lowland to empty into Lake Maracaibo  after a course of 210 mi (338 km).</p><p>Catawba Vko-'to-bsN North American Indian people of South Carolina,  U.S. The meaning of the name Catawba, which seems to have been  applied after European contact to several small bands of peoples in the  region of the Catawba River, is unknown. The peoples first encountered  by Hernando de Soto subsisted principally by farming, harvesting com,  beans, squash, and gourds. Fish and birds were also staples of their diet.  They traded bowls, baskets, and mats to other native groups and, later, to  colonists. Each village was governed by a council presided over by a  chief. After contact with European settlers, disease and other factors  diminished their numbers rapidly. In the 2000 U.S. census some 1,700  people identified themselves as of sole Catawba descent.</p><p>Catawba River River, southeastern U.S. Rising in North Carolina�s  Blue Ridge, it flows south into South Carolina, where it becomes the  Wateree River. It is 220 mi (350 km) long. With the Wateree, it forms an  important source of hydroelectric power for South Carolina.</p><p>catbird Any of several passerine species (family Mimidae) named for  their mewing calls, which they use in addition to song. The North Ameri�  can catbird ( Dumetella carolinensis) is 9 in. (23 cm) long and gray with  a black cap. It is found in gardens and thickets. The black catbird ( Mel-  anoptila glabrirostris) is found in coastal Yucatan. Three species of the  bowerbird family are also called catbirds; they are found in Australia, New  Guinea, and nearby islands and do not build bowers but hold territories  in the forest by loud singing.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>catch &#x25BA; Catherine II I 351</p><p>catch English round, or simple perpetual canon, for three or more unac�  companied voices. Catches were sung by men as a popular pastime in the  16th-19th centuries. Catch texts were often humorous or ribald, and in  some instances a pause in the melody in one voice was filled in by the  notes and text of another, creating a pun or change of meaning, especially  in the late-17th-century Restoration period.</p><p>Cateau-Cambresis \ka-to-ka I1 -bra- , ze\ / Treaty of (April 3, 1559)  Agreement marking the end of the 65-year struggle (1494-1559) between  France and Spain for the control of Italy. France gave up its claims to  Italian territory, leaving Habsburg Spain the dominant power there. France  returned Savoy and Piedmont to Spain�s ally Emmanuel-Philibert of  Savoy (1528-80) and restored Corsica to Genoa. Elsewhere, France  retained Calais, which it had seized from England in 1558, and the bish�  oprics of Toul, Metz, and Verdun, taken from Emperor Charles V.</p><p>catechesis See kerygma and catechesis</p><p>catechism Manual of religious instruction usually arranged in the form  of questions and answers and used to instruct the young, win converts,  and testify to the faith. The medieval catechism concentrated on the mean�  ing of faith, hope, and charity. Later catechisms added other subjects and  became more important following the Reformation and the invention of  the printing press. Martin Luther�s Small Catechism (1529) added discus�  sions of baptism and the Eucharist. John Calvin published a children�s cat�  echism in 1542. The Anglican catechism is included in the Book of  Common Prayer. The Baltimore Catechism (1885) is the Catholic cat�  echism best known in the U.S. In 1992 the Vatican issued a new univer�  sal Catechism of the Catholic Church.</p><p>catecholamine \ l ka-t3- , ko-b-,men\ Any naturally occurring amine  functioning as a neurotransmitter or hormone, including dopamine, norepi�  nephrine, and epinephrine. All are derived from tyrosine and have a catechol  group (benzene ring with two hydroxyl groups) with an attached amine  group. Neurons in the brain, in the adrenal gland, and in some sympa�  thetic nerve fibres produce different catecholamines.</p><p>categorical imperative In Immanuel Kant�s moral philosophy, an  imperative that presents an action as unconditionally necessary (e.g.,  �Thou shalt not kill�), as opposed to an imperative that presents an action  as necessary only on condition that the agent wills something else (e.g.,  �Pay your debts on time, if you want to be able to obtain a mortgage�). Kant  held that there was only one formally categorical imperative, from which  all specific moral imperatives could be derived. In one famous formulation,  it is: �Act only according to that maxim by which you can at the same time  will that it should become a universal law.� See also deontological ethics.</p><p>categorical proposition In syllogistic, a proposition in which the  predicate is affirmed or denied of all or part of the subject. Thus, cat�  egorical propositions are of four basic forms: �Every S is P,� �No S is P,�  �Some S is P,� and �Some S is not P.� These are designated by the letters  A, E, I, and O, respectively; thus, �Every man is mortal� is an  A-proposition. Categorical propositions are to be distinguished from com�  pound and complex propositions, into which they can enter as integral  terms. In particular, they contrast especially with hypothetical proposi�  tions, such as �If every man is mortal, then Socrates is mortal.�</p><p>caterpillar Larva of a butterfly or moth. Caterpillars have a cylindrical  body consisting of 13 segments, with three pairs of legs on the thorax and  �prolegs� on the abdomen. The head has six eyes on each side, short  antennae, and strong jaws. Though not true worms, many caterpillars are  called worms (e.g., the inchworm, or looper, and the cutworm).  Caterpillar-like larvae are also found in other insect groups (e.g., sawflies  and scorpionflies).</p><p>catfish Any of about 2,500 species of scale-less, mostly freshwater,  fishes (order Siluriformes) related to carp and minnows and named for their  whiskerlike barbels (fleshy feelers). All species have at least one pair of  barbels on the upper jaw, and some have a pair on the snout and addi�  tional pairs on the chin. Many species possess spines that may be asso�  ciated with venom glands. Found almost worldwide, they are generally  bottom-dwelling scavengers that feed on almost any kind of plant or ani�  mal matter. Species vary from 1.5 in. to 15 ft (4 cm-4.5 m) long and may  weigh up to 660 lbs (300 kg). Many small species are popular aquarium  fishes; many large species are used for food.</p><p>Cathari Vka-tho-.rA or Albigensians \al-b9-'jen-se-onz\ Heretical  Christian sect that flourished in Western Europe in the 12th�13th century.</p><p>The Cathari adhered to the dualist belief that the material world is evil  and that humans must renounce the world to free their spirits, which are  good and long for communion with God. Jesus was seen as an angel  whose human suffering and death were an illusion. Followers divided  themselves into the �perfect,� who had to maintain the highest moral  standards, and ordinary �believers,� of whom less was expected. By 1200  they had established 11 bishoprics in France and Italy. In an effort to stamp  out their heresy, Pope Innocent III declared the Albigensian Crusade, in  which the populace in Cathar regions was indiscriminately massacred.  Persecution through the Inquisition, sanctioned by St. Louis IX, was even  more effective, and when the Cathar stronghold of Montsegur fell in 1244,  most Cathari fled to Italy. The movement disappeared in the 15th century.</p><p>catharsis \k3-'thar-s3s\ Purging or purification of emotions through art.  The term is derived from the Greek katharsis (�purgation,� �cleansing�),  a medical term used by Aristotle as a metaphor to describe the effects of  dramatic tragedy on the spectator: by arousing vicarious pity and terror,  tragedy directs the spectator�s own anxieties outward and, through sym�  pathetic identification with the tragic protagonist, purges them.</p><p>Cathay \ka-'tha\ Former name for China, especially northern China. The  word is derived from Khitay, the name of a seminomadic people who  dominated northern China in the 10th� 12th century. By the time of Geng�  his Khan, the Mongols had begun referring to northern China as Kitai (still  the Russian word for China). The name may have been introduced to  Europe by returning Franciscan friars c. 1254, but it was Marco Polo�s  Travels 50 years later that put Cathay�s image before the European public.</p><p>cathedral Church, often large and magnificent, in which a residential  bishop has his official seat. Cathedrals are usually embellished versions  of early Christian basilicas; their construction, on an ever-larger scale, was  a major preoccupation throughout Europe in the Middle Ages. Masonry  vaulting replaced the earlier timber roofs, and the basilican plan grew  more complex. Above the arches of the nave, and below the clerestory,  was the triforium, an arcaded upper story that often contained vaulted tri�  bune galleries open to the nave. The portion containing seats for the choir,  usually east of the transept, was called the chancel. Between the chancel  and the sanctuary (high altar) was the presbytery, a raised area occupied  only by clergy. The chapter house, a popular feature of English cathe�  drals, was a chamber, typically octagonal, in which business was trans�  acted. Small chapels, including the founder�s chantry and the Lady Chapel  (dedicated to the Virgin Mary) were often added. Many cathedrals of the  Ile-de-France region were remodeled to embody a chevet, or arc of radi�  ating chapels, on the eastern wall, a feature reflected in England in West�  minster Abbey and Canterbury Cathedral.</p><p>Cather Vka-thorV Willa orig. Wilella Sibert Cather (b. Dec. 7,  1873, near Winchester, Va., U.S.�d. April 24, 1947, New York, N.Y.)  U.S. novelist. Cather moved with her family to Nebraska at age 9; she  returned east 12 years later, eventually settling in New York. The Troll  Garden (1905), her first short-story collection, contains some of her best-  known work. The novels O Pioneers! (1913) and My Antonia (1918),  often judged her finest achievement, celebrate frontier spirit and courage.  Song of the Lark (1915), Youth and the Bright Medusa (1920), and other  works reflect the struggle of a talent to emerge from small-town provin�  cialism. One of Ours (1922, Pulitzer Prize) and A Lost Lady (1923) mourn  the loss of the pioneer spirit. Pioneers of earlier eras also inspired Death  Comes for the Archbishop (1927) and Shadows on the Rock (1931).</p><p>Catherine I Russian Yekaterina Alekseyevna orig. Marta  Skowronska (b. April 15, 1684�d. May 17, 1727, St. Petersburg,  Russia) Second wife of Peter I and empress of Russia (1725-27). A peas�  ant woman of Baltic origin, she became Peter�s mistress in 1702. In 1703,  after the birth of their first child, she was received into the Russian Ortho�  dox church and rechristened. She married Peter in 1712 and in 1724 was  crowned empress-consort. After Peter�s death (1725), she served two  years as empress of Russia.</p><p>Catherine II Russian Yekaterina Alekseyevna orig.

Nov. 17,  1796, Tsarskoye Selo, near St. Petersburg, Russia) German-born empress  of Russia (1762-96). The daughter of an obscure German prince, she was  chosen at age 14 to be the wife of the future Peter III. The marriage was  a complete failure. Because her neurotic husband was incapable of rul�  ing, the ambitious Catherine saw the possibility of eliminating him and  governing Russia herself.

In her 34-year reign she led Russia into full participation in European  political and cultural life. With her ministers she reorganized the admin�  istration and law of the Russian Empire and extended Russian territory,  adding the Crimea and much of Poland. Though she had once intended  to emancipate the serfs, she instead strengthened the system she had once  condemned as inhuman. She had great energy and wide interests, and her  personal life was notable for her many lovers, including Grigory Potemkin.</p><p>Catherine de Medicis \ka-tren-d3-ma-de-'ses\ orig. Caterina de'  Medici (b. April 13, 1519, Florence�d. Jan. 5, 1589, Blois, France)  Queen consort of Henry II (1547-59), mother of Francis II, Charles IX, and  Henry III, and regent of France (1560-74). A member of the Medici fam�  ily, she married Henry in 1533 and bore him 10 children. She became  queen when Henry inherited the crown in 1547, and she greatly mourned  his accidental death in 1559. After their son Francis became king, she  began a long struggle with members of the Guise family, extremists who  sought to dominate the crown. After Francis�s premature death in 1560,  she became regent for Charles IX until 1563 and dominated the rest of  his reign until 1574. She attempted to settle the Wars of Religion between  Catholics and Huguenots. She has traditionally been blamed for the Mas�  sacre of Saint Bartholomew's Day, but, though she authorized the assas�  sination of Gaspard II de Coligny and his principal followers, it appears  that she did not authorize the massacre that followed.</p><p>Catherine Howard (b. c. 1520�d. Feb. 13, 1542, London, Eng.)  Fifth wife of Henry VIII of England. The granddaughter of the 2nd duke  of Norfolk, she became a maid of honour to Anne of Cleves, Henry�s  fourth wife. After Henry had his marriage to Anne annulled, he married  Catherine (1540). In 1541 he learned that Catherine had had several affairs  before their marriage and that she also had probably committed adultery.  Incensed, he had Parliament pass a bill in 1542 declaring it treason for  an unchaste woman to marry the king. Catherine was beheaded two days  later in the Tower of London.</p><p>Catherine of Alexandria, Saint (d. c. early 4th century, Alexan�  dria, Egypt; feast day November 25) Early Christian martyr. According  to tradition, she was a learned girl of noble birth who protested the per�  secution of Christians during the reign of the Roman emperor Maxentius.  She converted the emperor�s wife and defeated in debate the best schol�  ars he sent to oppose her. She was sentenced to be killed with a spiked  wheel (the Catherine wheel), but, when it broke, she was beheaded  instead. Her body was transported by angels to the top of Mount Sinai.  One of the most popular saints of the Middle Ages, she was patron of  philosophers and scholars. Her historicity is doubtful.</p><p>Catherine of Aragon (b. Dec. 16, 1485, Alcala de Henares,  Spain�d.

She gave birth to six children,  but only one daughter (later Mary I)  survived infancy. Henry�s desire for  a legitimate male heir prompted him  in 1527 to appeal to Rome for an  annulment, but Pope Clement VII  refused, triggering the break between  Henry and Rome and leading to the  English Reformation. In 1533 Henry  had his own archbishop of Canter�  bury, Thomas Cranmer, annul the  marriage, and Catherine spent her  last years isolated from public life.</p><p>Catherine of Braganza (b.</p><p>Nov. 25,1638, Vila Vigosa, Port.�d.</p><p>Dec. 31, 1705, Lisbon) Portuguese  wife of Charles II of England. She  was married to Charles in 1662 as  part of an alliance between England  and Portugal, bringing England trad�  ing privileges and the port cities of  Tangier and Bombay (now Mumbai). She produced no heir. Though not  a faithful husband, Charles defended her against accusations of scheming</p><p>to poison him. She helped convert him to Catholicism shortly before his  death. In 1692 she returned to Portugal, and in 1704 she governed the  country as regent for her ailing brother, Pedro II.</p><p>Catherine of Siena, Saint orig. Caterina Benincasa (b.

She joined  the Dominican third order in Siena in 1363 and soon became known for  her holiness and severe asceticism. Catherine called for a Crusade against  the Muslims as a means of calming domestic conflict in Italy. She also  played a major role in returning the papacy from Avignon to Rome (see  Avignon papacy). Her writings include four treatises on religious mysti�  cism known as The Dialogue of St. Catherine.</p><p>Catherine Parr (b. 1512�d. Sept. 7, 1548) Sixth and last wife of King  Henry VIII of England. The daughter of an official in the royal household,  she had been widowed twice by the time she married Henry in 1543. She  exerted a beneficial influence on the increasingly paranoid king and devel�  oped close friendships with his children by previous marriages. After  Henry�s death in 1547, she married Baron Thomas Seymour but died  shortly after giving birth to a daughter.</p><p>catheterization V.ka-tho-ts-ro-'za-shonV Threading of a flexible tube  (catheter) through a channel in the body to inject drugs or a contrast  medium, measure and record flow and pressures, inspect structures, take  samples, diagnose disorders, or clear blockages.

After the Reformation, Roman Catholics in  Britain could not purchase land, hold offices or seats in Parliament, inherit  property, or practice their religion without incurring civil penalties. Irish  Catholics faced similar limitations. By the late 18th century, Catholicism  no longer seemed so great a social and political danger, and a series of  laws, culminating in the Emancipation Act of 1829, eased the restrictions.  A major figure in the struggle for full emancipation was Daniel O'Connell.</p><p>Catholic League (1609-35) Military alliance of the Catholic powers  of Germany, led by Maximilian I, duke of Bavaria, and designed to stem  the growth of Protestantism in Germany. Plans for a league had long been  discussed, but the formation of the Protestant Union in 1608 finally caused  the Catholics to unite. In alliance with the Habsburg emperors, the  League�s forces, led by Graf von Tilly, played a key role in the Thirty Years'  War.

Depending on the breed, mature bulls (fertile males) weigh  1,000-4,000 lbs (450-1,800 kg); cows (fertile females) weigh 800-2,400  lbs (360-1,080 kg). All modern cattle are believed to belong to either of  two species (Bos indicus or B. taurus) or to be crosses of the two. About  277 identifiable breeds include those prominent in beef production (e.g.,  Angus, Hereford, and shorthorn) and dairy farming.

Caucasian languages, spoken by some nine  million people, are divided into three subgroups: the South Caucasian, or  Kartvelian family; the Northwest Caucasian, or Abkhaz-Adyghe lan�  guages; and the Northeast Caucasian, or Nakh-Dagestanian languages.  Kartvelian, with more than 4.5 million speakers, comprises four relatively  closely related languages, including Georgian. Northwest Caucasian lan�  guages include Abkhaz and a chain of dialects called collectively Circas�  sian. The Northeast Caucasian languages are further divided into two  groups, Nakh and Dagestanian. The Nakh languages include Chechen and  Ingush, spoken by more than a million people mainly in Chechnya and  Ingushetia. Dagestanian is an extraordinarily diversified group of 25-30  languages spoken by some 1.7 million people mainly in northern Azer�  baijan and the Republic of Dagestan. Several Dagestanian languages,  including Avar, Lak, Dargva, and Lezgi, number their speakers in the  hundreds of thousands; others are spoken in only a few villages. In spite  of their great diversity, most Caucasian languages have in common large  consonant inventories; in some languages the number of consonants dis�  tinguished approaches 80. Those Caucasian languages with standard writ�  ten forms employ the Cyrillic alphabet, with the prominent exception of  Georgian. An effort is being made to introduce the Latin alphabet for  Chechen in Chechnya.</p><p>Caucasoid See race</p><p>Caucasus Vko-ko-sosV or Caucasia \k6-'ka-zho\ Mountainous region,  between the Black and Caspian seas.

According to David Hume, when we say of two types of object  or event that �X causes Y� (e.g., fire causes smoke), we mean that (i) Xs  are �constantly conjoined� with Ys, (ii) Ys follow Xs and not vice versa,  and (iii) there is a �necessary connection� between Xs and Ys such that  whenever an X occurs, a Y must follow. Unlike the ideas of contiguity  and succession, however, the idea of necessary connection is subjective,  in the sense that it derives from the act of contemplating objects or events  that we have experienced as being constantly conjoined and succeeding  one another in a certain order, rather than from any observable properties  in the objects or events themselves. This idea is the basis of the classic  problem of induction, which Hume formulated. Hume�s definition of cau�  sation is an example of a �regularity� analysis. Other types of analysis  include counterfactual analysis, manipulation analysis, and probabilistic  analysis.</p><p>caustic soda Sodium hydroxide (NaOH), an inorganic compound. The  alkalies called caustic soda and caustic potash (potassium hydroxide) are  very important industrial chemicals, with uses in the manufacture of  soaps, glass, and numerous other products.

In his teens he was a singer  under Claudio Monteverdi at St. Mark's Basiuca, Venice. Also an organist,  he would rise to the post of maestro di cappella there in 1668. He wrote  some 30 operas for Venice�s public opera houses. The most popular opera  composer of the decades following Monteverdi�s death, he was the lat�  ter�s leading successor, his chief rival for that status being Antonio Cesti  (1623-69).

When used in com�  bination with other military forces, its main duties included gathering  information about the enemy, screening movements of its own army, pur�  suing a defeated enemy, striking suddenly at detected weak points, turn�  ing exposed flanks, and exploiting a penetration or breakthrough. In the  late 19th century, largely because of the introduction of repeating rifles  and machine guns, cavalry lost much of its former value. By World War  I, a cavalry charge against a line of entrenched troops with rapid-firing  small arms was suicidal. Armoured vehicles soon replaced horses, and by  the 1950s no modern army had horse-mounted units. Today�s units des�  ignated �cavalry� employ helicopters and light armoured vehicles in ways  analogous to horse cavalry.</p><p>cave Naturally formed underground cavity. A cave often consists of a  number of underground chambers, constituting a series of caverns. An  assemblage of such caverns interconnected by smaller passageways makes  up a cave system. Primary caves, such as lava tubes and coral caves,  develop during the time when the host matrix is solidifying or being depos�  ited. Secondary caves, such as marine grottoes, originate after the host  matrix has been deposited or consolidated. Most caves are of the latter type,  including solution caves formed by the chemical dissolution of a soluble  host rock that has been weakened by fracturing and mechanical erosion;  Mammoth Cave and Carlsbad Caverns are examples of solution caves.</p><p>Cavell Yka-volV Edith (Louisa) (b.

Most true caviar is  produced in Russia and Iran, from fish taken from the Caspian and Black  seas. The best grade, beluga, is prepared from large black or gray eggs;  fresh beluga is relatively scarce and thus expensive. Caviar may be pas�  teurized for longer storage.

The islands include Grand  Cayman (the largest and the location of the capital, George Town), Little  Cayman, and Cayman Brae. Though discovered by Christopher Columbus  in 1503, the islands were never occupied by the Spanish. Ceded to the  British in 1670, they were subsequently settled by the English arriving  from Jamaica. The islands were administered as a dependency of Jamaica  until Jamaican independence in 1962; a constitution was enacted in 1972.  The governor of the Cayman Islands is appointed by the British crown.

It began in 1928 as the Columbia Broadcasting System, a small  radio network directed by William S. Paley. By offering programming free  to affiliated stations in return for their agreement to broadcast sponsored  shows, Paley built the network from 22 stations to 114 in 10 years. Such  stars as Fred Allen, Bing Crosby, and Kate Smith increased audience ratings  into the 1940s. Jack Benny, Ed Sullivan, Lucille Ball, Mary Tyler Moore, and  Walter Cronkite made CBS the dominant television network into the  1970s. The company diversified into several other fields, but only Colum�  bia Records was successful, and the corporation sold all its other divi�  sions in 1985 to concentrate on broadcasting. A decline in ratings and in  the number of affiliated stations led to its sale to Westinghouse Electric  Corp. in 1995.

Poor nutrient absorption causes foul, bulky, fatty stools; malnu�  trition; stunting of growth; and anemia similar to pernicious anemia. It  can run in families. Children begin having intermittent intestinal upset,  diarrhea, and wasting at 6-21 months. In adults it usually begins after 30,  with appetite loss, depression, irritability, and diarrhea. Symptoms in  advanced cases stem from nutritional deficiencies and may require sup�  portive measures. A high-protein diet low in glutens and saturated fats  usually relieves symptoms.</p><p>celibacy Vse-b-b3-se\ The deliberate abstinence from sexual activity,  usually in connection with a religious role or practice. It has existed in  some form in most world religions. It may indicate a person�s ritual purity  (sexual relations being viewed as polluting) or may be adopted to facili�  tate spiritual advancement (as sexual activity would take place only within  the bonds of matrimony, marriage and family were seen as an entangling  distraction). In shamanistic religions, shamans are often celibate. In Hin�  duism, �holy men� (or women) who have left ordinary secular life to seek  final liberation are celibate. Buddhism began as a celibate order, though  many sects have since given up celibacy. Chinese taoism has monastics  and independent celibate adepts. Islam has no institutional celibacy, but  individuals may embrace it for personal spiritual advancement. Judaism  has prescribed periods of abstinence, but long-term celibacy has not  played a large role. The early Christian church tended to regard celibacy  as superior to marriage. Since the 12th century it has been the rule for  Roman Catholic clergy, though clerical celibacy was never adopted by  Protestantism.</p><p>Celine \sa-'len\, Louis-Ferdinand orig. Louis-Ferdinand  Destouches (b. May 27, 1894, Courbevoie, near Paris, France�d. July  1, 1961, Meudon) French writer. Celine was born into poverty. In World  War I he suffered wounds and shell shock, the mental and physical effects  of which lingered throughout his life. From 1924 he practiced medicine.  His Journey to the End of Night (1932), about a man�s tortured search for  meaning, is written in a vehement and disjointed style that marked him  as a major innovator. Death on the Installment Plan (1936) is a bleak  portrayal of a world bereft of value, beauty, and decency. He thereafter  became increasingly conservative, anti-Semitic, and misanthropic. After  World War II he fled to Denmark as a suspected Nazi collaborator, but  he was later exonerated. His works include the trilogy Castle to Castle  (1957), North (1960), and Rigadoon (1969).</p><p>cell In biology, the basic unit of which all living things are composed;  the smallest structural unit of living matter that is able to function inde�  pendently. A single cell can be a complete organism in itself, as in bac�  teria and protozoans. Groups of specialized cells are organized into tissues  and organs in multicellular organisms such as higher plants and animals.  There are two distinct types of cells: prokaryotic cells, found only in bac�  teria (including blue-green algae, or cyanobacteria) , and eukaryotic cells,  composing all other life-forms. Though the structures of prokaryotic and  eukaryotic cells differ (see prokaryote, eukaryote), their molecular com�  positions and activities are very similar. The chief molecules in cells are  nucleic acids, proteins, and polysaccharides. A cell is bounded by a membrane  that enables it to exchange certain materials with its surroundings. In plant  cells, a rigid cell wall encloses this membrane.

Energy needed by the cell is released by the  mitochondria. The Golgi complex, stacks of flattened sacs, processes and packages  materials to be released from the cell in secretory vesicles. Digestive enzymes are  contained in lysosomes. Peroxisomes contain enzymes that detoxify dangerous sub�  stances. The centrosome contains the centrioles, which play a role in cell division.  The microvilli are fingerlike extensions found on certain cells. Cilia, hairlike struc�  tures that extend from the surface of many cells, can create movement of surround�  ing fluid. The nuclear envelope, a double membrane surrounding the nucleus,  contains pores that control the movement of substances into and out of the nucleo�  plasm. Chromatin, a combination of DNA and proteins that coil into chromosomes,  makes up much of the nucleoplasm. The dense nucleolus is the site of ribosome pro�  duction.</p><p>� MERRIAM-WEBSTER INC.</p><p>cella Vse-b\ or naos Vna-,as\ Enclosed body of a temple (as distinct from  the portico), in which the image of the deity was housed. In early Greek  and Roman architecture it was usually rectangular, with an entrance at  one end; the side walls were often extended to form a porch. In larger  temples the cella was sometimes open to the sky. In the Byzantine archi�  tectural tradition, the naos is the area of a central-plan church where the  liturgy is performed.</p><p>cellar Portion of a building beneath ground level, used for utilitarian and  storage purposes. It is often called a basement, especially when con�  structed as part of a foundation. A cellar used for food storage (e.g., a root  cellar) may be beneath a house or located outdoors, partly underground,  with the upper part mounded over with earth to maintain fairly constant  temperature and humidity; the entire enclosure may be concrete, or the  floor may be of dirt and the ceiling of timber.</p><p>Cellini Vcho-�le-neV Benvenuto (b.

In 1540 he  began his most famous work of this  type, a gold saltcellar encrusted with  enamel, for Francis I at Fontaineb�  leau; other royal commissions fol�  lowed. For Cosimo I he produced  large-scale sculpture in the round;  the bronze Perseus (1545-53) in the  Loggia dei Lanzi in Florence is his  masterpiece.

Its full name means �little violone��i.e.,  �little big viol.� Its proportions resemble those of the violin. Players hold  its body between the legs, its weight supported by a metal spike that  touches the floor. It has four strings, tuned an octave below those of the  viola. The cello was developed in the early 16th century along with the  violin and viola; later innovations increased its power. It gradually dis�  placed the bass viola da gamba in the 18th century, especially as a con-  tinuo instrument. It has been essential to chamber music ensembles for  250 years. The modern orchestra includes 6 to 12 cellos. In the 19th and  20th centuries it was increasingly used as a solo instrument.</p><p>cellular automata (CA) Simplest model of a spatially distributed  process that can be used to simulate various real-world processes. Cellu�  lar automata were invented in the 1940s by John von Neumann and Stanis�  lav/ Ulam at Los Alamos National Laboratory. They consist of a two-  dimensional array of cells that �evolve� step-by-step according to the state  of neighbouring cells and certain rules that depend on the simulation.  Though apparently simple, CAs are universal computers�that is, they can  do any computer-capable computation. The best-known cellular automa�  ton, John Conway�s �Game of Life� (1970), simulates the processes of  life, death, and population dynamics.</p><p>celluloid \'sel-y3-,l6id\ Name for the first synthetic plastic material,  developed in 1869. Made of a colloid of cellulose nitrate (nitrocellulose)  plasticized with camphor, it is tough, cheap to produce, and resistant to  water, oils, and dilute acids. It found a great variety of uses in combs,  films, toys, and many other mass-produced consumer goods. Though it  has been replaced in many uses by nonflammable synthetic polymers (origi�  nally cellulose acetate and Bakelite, then a host of others), it is still manu�  factured and used.</p><p>cellulose Complex carbohydrate (polysaccharide) consisting of 1,000-  3,000 or more glucose units in a linear chain structure that can pack into  fibres of great tensile strength. The basic structural component of plant  cell walls, cellulose is the most abundant of all naturally occurring organic  compounds (90% of cotton and 50% of wood). Mammals (including  humans) cannot digest cellulose, but bacteria in the rumens of cattle and  other ruminants and protozoans in the gut of termites produce enzymes that  can break it down. Soil fungi can also break down cellulose. Its most  important uses are in wood, paper, and fibre products, as an ethanol and  methanol source, and specialized applications. Cellulose derivatives are  used in plastics, photographic films, rayon fibres, cellophane, coatings,  explosives (e.g., nitrocellulose), and foods (e.g., the stabilizer and thick�  ener carboxymethylcellulose).</p><p>Celsius Vsel-se-3s\, Anders (b.

In 1733 he published a collection  of 316 observations of the aurora borealis. In 1744 he built the Uppsala  Observatory. He is best known for his invention of the Celsius (often  called centigrade) thermometer scale (1742), which set the freezing point  of water at 0� and the boiling point of water at 100�.</p><p>Celsus \'sel-s9s\, Aulus Cornelius (fl. 1st century ad) Roman medi�  cal writer. His famous treatise De medicina, a major source of knowledge  of early medicine, shows that it was remarkably advanced, urging clean�  liness and use of antiseptics, describing facial skin grafting, and stating  the four cardinal signs of inflammation. The book�s three parts discuss  diseases requiring diet, drug, or surgical therapy.</p><p>Celt Vkelt, 'selt\ Any member of an early Indo-European people who  spread over much of Europe from the 2nd millennium to the 1st century  bc. They were absorbed into the Roman Empire as Britons, Gauls, Boii,  Galatians, and Celtiberians. Early archaeological evidence (c. 700 bc)  comes from the Hallstatt site in Austria. People of this Iron Age culture  controlled trade routes along the Rhone, Seine, Rhine, and Danube riv�  ers. As they moved west, Hallstatt warriors introduced the use of iron,  which helped them dominate other Celtic tribes. By the mid 5th century  bc, the La Tene culture emerged along the Rhine and moved into eastern  Europe and the British Isles. Celts sacked Rome c. 390 and raided the  whole peninsula, then settled south of the Alps (Cisalpine Gaul) and men�  aced Rome until they were defeated in 225 bc. In the Balkans, they sacked  Delphi in 279 but were defeated by the Aetolians. They crossed to Ana�</p><p>tolia and looted until they were subdued by Attalus I about 230 bc. Rome  controlled Cisalpine Gaul by 192 and in 124 took territory beyond the  Alps. In Transalpine Gaul, from the Rhine and the Alps west, the Celts  were pressed by Germanic tribes from the west and Romans from the  south. By 58 Julius Caesar had begun campaigns to annex all of Gaul.  Celtic settlement of Britain and Ireland is deduced from archaeological  and linguistic evidence. The Celtic social system comprised a warrior  aristocracy and freemen farmers; Druids, with magico-religious duties,  ranked higher than warriors. They had a mixed farming economy. Their  oral literary composition was highly developed, as was their art; they  manufactured gold and silver jewelry, swords and scabbards, and shields  inlaid with enamel.</p><p>Celtiberia \,sel-t9- , bir-e-9\ Mountainous district, ancient Spain. Located  in northeastern Spain between the Ebro and Tagus rivers, it had long been  inhabited before it was occupied in the 3d century bc by tribes of mixed  Iberian and Celtic stock. The Celtiberians first submitted to Rome in the  early 2nd century bc but were not completely dominated until 133 bc. Exca�  vated horse bits, daggers, and shield fittings attest to their warlike nature.</p><p>Celtic \'kel-tik\ languages Branch of the Indo-European language fam�  ily spoken across a broad area of western and central Europe by the Celts  in pre-Roman and Roman times, now confined to small coastal areas of  northwestern Europe. Celtic can be divided into a continental group of  languages (all extinct) and an insular group. Attestation of Insular Celtic  begins around the time Continental Celtic fades from the scene as Celtic  tongues gave way to Latin and other languages on the European conti�  nent. The Insular Celtic languages are conventionally divided into  Goidelic (Irish, Manx, and Scottish Gaelic) and Brythonic (Welsh, Cornish,  and Breton). Traditional Cornish was supplanted by English at the end of  the 18th century. Manx, spoken on the Isle of Man, expired in the 20th  century with the death of the last reputed native speaker in 1974. Both  Manx and Cornish have been revived by enthusiasts, though neither can  be considered community languages.</p><p>Celtic religion Beliefs and practices of the ancient Celts of Gaul and  the British Isles. Celtic worship centred on the interplay of the divine ele�  ment with the natural world. Springs, rivers, and hills were thought to be  inhabited by guardian spirits, usually female. Some gods were widely  worshiped; lesser deities were associated with particular tribes or places.  The most honoured god was Lugus, who was skilled in all the arts. Cer-  nunnos was lord of the animals; the goddess of mares and fertility was  called Epona (Gaul), Macha (Ireland), or Rhiannon (Britain). Goddesses  often came in groups of three. The priests of Celtic religion were the Dru�  ids; they maintained an oral tradition and left no writings. Seasonal fes�  tivals included Samhain (November 1), which marked summer�s end and  served as a feast of the dead, and Beltane (May 1). Oak trees, holly, and  mistletoe were considered sacred. The Celts believed in life after death  as well as transmigration of souls. See also Bran; Brigit.</p><p>cement Agent that binds concrete and mortar. Cements are finely ground  powders that, when mixed with water, set to a hard mass. The cement of  2,000 years ago was a mixture of ash and lime. Volcanic ash mined near  the city of Puteoli (now Pozzuoli), near Naples, was particularly rich in  essential aluminosilicate minerals, giving rise to the pozzolana cement of  the Roman era. See also Portland cement.</p><p>cementation In geology, the hardening and welding of clastic sedi�  ments (those formed from preexisting rock fragments) by the precipitation  of mineral matter in the pore spaces. It is the last stage in the formation of  sedimentary rock. Many minerals may act as cements; the most common  is silica (generally quartz), but calcite and other carbonates also occur, as  do iron oxides, barite, anhydrite, zeolites, and clay minerals.</p><p>Cenis \s9-'ne\, Mount French Mont Cenis V.mc^-so-'neV Italian  Moncenisio Vmon-cha-'ne-zyoX Massif and pass, Alps. Located in  southeastern France west of Turin, Italy, the pass was an invasion route  from earliest times and is traversed by a road 24 mi (38 km) long, built  by Napoleon in 1803-10. The road climbs to Mount Cenis Pass (eleva�  tion 6,834 ft [2,083 m]) and passes between two peaks more than 8,200  ft (2,500 m) high. The Mount Cenis railway tunnel, 8.5 mi (14 km) long,  was the first great tunnel through the Alps (opened 1871).

During the Qin  (221-206 bc) and Han (206 bc-ad 220) dynasties, the censor�s function  was to criticize the emperor�s acts, but in later periods the censorate was  expanded and became an instrument for imperial control of the bureau�  cracy. Censors checked important documents, supervised construction  projects, reviewed judicial proceedings, kept watch over state property,  and looked for cases of subversion and corruption.</p><p>censorship Act of changing or suppressing speech or writing that is  considered subversive of the common good. In the past, most govern�  ments believed it their duty to regulate the morals of their people; only  with the rise in the status of the individual and individual rights did cen�  sorship come to seem objectionable. Censorship may be preemptive (pre�  venting the publication or broadcast of undesirable information) or  punitive (punishing those who publish or broadcast offending material).  In Europe, both the Roman Catholic and Protestant churches practiced  censorship, as did the absolute monarchies of the 17th and 18th centuries.  Authoritarian governments such as those in China, Cuba, Saudi Arabia,  and the former Soviet Union have employed pervasive censorship, which  is generally opposed by underground movements engaged in the circula�  tion of samizdat literature. In the U.S. in the 20th century, censorship  focused largely on works of fiction deemed guilty of obscenity (e.g., James  Joyce�s Ulysses and D.H. Lawrence�s Lady Chatterley�s Lover), though  periodic acts of political censorship also occurred (e.g., the effort to purge  school textbooks of possible left-wing content in the 1950s). In the late  20th century, some called for censorship of so-called hate speech, lan�  guage deemed threatening (or sometimes merely offensive) to various  subsections of the population. Censorship in the U.S. is usually opposed  by the American Civil Liberties Union. In Germany after World War II it  became a crime to deny the Holocaust or to publish pro-Nazi publica�  tions. See also Pentagon Papers.</p><p>census Enumeration of people, houses, firms, or other important items  in a country or region at a particular time. The first U.S. population cen�  sus was taken in 1790 to establish a basis for representation in Congress.  Censuses were taken in England, France, and Canada in 1801, 1836, and  1871, respectively. China was the last major country to report a census,  in 1953. Census information is obtained by using a fixed questionnaire  covering such topics as place of residence, sex, age, marital status, occu�  pation, citizenship, language, ethnicity, religious affiliation, and educa�  tion. From the responses demographers derive data on population  distribution, household and family composition, internal migration, labor-  force participation, and other topics.

They  were best known for their battle with the Lapiths, occasioned by their  attempt to carry off the bride of a Lapith prince. Centaurs were often  depicted drawing Dionysus' chariot or ridden by Eros, in reference to their  drunken and amorous habits. Their king Chiron, however, was notable for  being civilized, gentle, and the tutor of heroes.</p><p>Centaur object Icy body, similar to an asteroid in size but to a comet  in composition, that orbits the Sun mainly between the orbits of Jupiter</p><p>and Neptune. The first known Centaur object, Chiron, was found in 1977,  but its affinity with comets was not recognized until more than a decade  later. Subsequently, dozens of Centaur objects have been reported. They  are thought to have originated in the Kuiper belt, a vast reservoir of comet  nuclei beyond Neptune�s orbit.</p><p>Center Party German political party formed to support Roman Catho�  lic interests. It was active in the Second Reich from the 1870s, when it  came into conflict with Otto von Bismarck in the Kulturkampf, to 1933,  when it was dissolved by the Nazi-dominated government. It was the first  party of imperial Germany to cut across class and state lines, but because  it represented the Roman Catholics, who were concentrated in southern  Germany, it never won a parliamentary majority.</p><p>centering See falsework</p><p>Centers for Disease Control and Prevention (CDC) Agency of  the U.S. Department of Health and Human Services, headquartered in  Atlanta, whose mission is �to promote health and quality of life by pre�  venting and controlling disease, injury, and disability.� Part of the Public  Health Service, it was founded in 1946 as the Communicable Disease  Center to fight malaria and other contagious diseases. As its scope wid�  ened to polio, smallpox, and disease surveillance, the name was changed  to the Center for Disease Control and later pluralized.

Languages:  French, Sango (both official), several others. Religions: Christianity  (mostly other Christians [largely unaffiliated and independent]; also  Roman Catholic, Protestant), Islam, traditional beliefs. Currency: CFA  franc. A landlocked country, it consists of a large rolling plateau. The  northern half is characterized by savanna and is drained by tributaries of  the Chari River. The southern half is densely forested. The country has a  developing free-enterprise economy of mixed state and private structure,  with agriculture as the main component. It is a republic with one legis�  lative body; its chief of state is the president, assisted by the prime min�  ister. For several centuries before the arrival of Europeans, the territory  was exploited by slave traders. The French explored and claimed central  Africa and in 1889 established a post at Bangui. They subsequently par�  titioned the territory into several colonies, one of which was Ubangi-Shari  (Oubangui-Chari), the future Central African Republic; it later became  part of French Equatorial Africa. Ubangi-Shari became a French overseas  territory in 1946. It became an autonomous republic within the French  Community in 1958 and achieved independence in 1960. In 1965 the mili�  tary overthrew a civilian government and installed Jean-Bedel Bokassa,  who in 1976 renamed the country the Central African Empire.

It extends from the southern border of Mexico to the north�  western border of Colombia and from the Pacific Ocean to the Caribbean  Sea. It includes Guatemala, Belize, Honduras, El Salvador, Nicaragua,  Costa Rica, and Panama. Some geographers also include five states of  Mexico: Quintana Roo, Yucatan, Campeche, Tabasco, and Chiapas. Area:  201,594 sq mi (522,129 sq km). Two-thirds of the population is of mixed  American Indian and Spanish ancestry. Language: Spanish (official),  except Belize (English, official); also American Indian languages. Reli�  gion: chiefly Roman Catholicism. The region is largely hilly or moun�  tainous, with humid swamps and lowlands extending along both coasts.  Tajumulco Volcano, in western Guatemala, is the highest point, elevation  13,845 ft (4,220 m). The region has some 40 volcanoes, many of them  active, and is prone to severe seismic activity. The volcanic zones have  fertile soil and are productive agricultural areas. Central America was long  inhabited by indigenous peoples, including the Maya, before the Spanish  arrived and conquered the region in the early 16th century; they contin�  ued to rule for about 300 years. Christopher Columbus skirted the Atlantic  coast from Honduras to the Gulf of Darien in 1502; the first European  settlement (1510) was on the gulf. Spain organized the region (except  Panama) into the Captaincy General of Guatemala (c. 1543). The English  arrived in the 17th century, settling what became British Honduras (Bel�  ize). Independence from Spanish rule came in 1821, and in 1823 the  United Provinces of Central America was formed (Guatemala, El Salva�  dor, Honduras, Nicaragua, and Costa Rica). British Honduras, still a  colony, did not join the federation, and Panama remained part of Colom�  bia. In 1824 the federation adopted a constitution, but in 1838 Costa Rica,  Honduras, and Nicaragua seceded, thus effectively terminating the fed�  eration. Treaties of amity were drawn up at a conference of Central Ameri�  can states in Washington, D.C. (1923). The Central American Common  Market was established in 1960 to create a customs union and promote  economic cooperation.</p><p>Central Asian arts Literary, performing, and visual arts of Afghani�  stan, Azerbaijan, Kazakhstan, Kyrgyzstan, Mongolia, Nepal, Tibet, Turk�  menistan, Uzbekistan, and parts of China and Russia. The term usually  denotes only those traditions not influenced by the Islamic arts. Tibetan  developed as a literary language from the 7th century as a result of cul�  tural contacts with neighbouring Buddhist countries to the south, on the  Indian subcontinent. Most works produced between the 7th and 13th cen�  turies are skillful translations of Buddhist works from Sanskrit, after</p><p>which a vast body of orthodox Buddhist works of purely Tibetan origin  was built up. Mongolian literature began in the 13th century with  chronicles of Genghis Khan and his successors, but from the late 16th cen�  tury Mongolian literature was profoundly influenced by Buddhism. The  variety of musical styles in Central Asia ranges from the systematically  organized classical music of the Turkic peoples, to the notated religious  chants of Buddhists in Tibet, to the highly varied folk music styles of the  Mongols, Siberians, and numerous other ethnic groups. Two main types  of performance predominate throughout Tibet, Nepal, Sikkim, Bhutan,  and Mongolia: those related to shamanism and those derived from Bud�  dhism. Music performed on drums and stringed instruments accompanied  shamanistic trances. The performance of Buddhist monastic dances and  morality plays is also accompanied by various drums and horn instru�  ments. The performing arts of the Turkic peoples are very different from  these other traditions because of the influence of Islam. The tribes of Cen�  tral Asia shared, for the most part, a �nomadic� Scytho-Altaic visual art  that favoured animal and hunting motifs in objects such as belts and jew�  elry. Contacts with the Greco-Roman world and with India, Iran, and  China also left their mark; Hellenistic influence culminated in the Kus-  han style of Gandhara. The most important pre-Islamic influence on Cen�  tral Asia�s visual arts, however, was Buddhism, which was reflected in  the subject matter of sculptures and bas-reliefs. Nepal�s traditions in archi�  tecture and painting were adaptations of those of India, whether the  themes were Hindu or Buddhist. Buddhist religious art was gradually  introduced into Tibet from the 8th century, and a distinctive Tibetan imag�  ery was subsequently developed. See also Gandhara art; Kushan art;  Scythian art.</p><p>central bank Institution, such as the U.S. Federal Reserve System,  charged with regulating the size of a nation�s money supply, the availabil�  ity and cost of credit, and the foreign exchange value of its currency (see  foreign exchange). Central banks act as the fiscal agent of the government,  issuing notes to be used as legal tender, supervising the operations of the  commercial banking system, and implementing monetary policy. By  increasing or decreasing the supply of money and credit, they affect inter�  est rates, thereby influencing the economy. Modem central banks regu�  late the money supply by buying and selling assets (e.g., through the  purchase or sale of government securities). They may also raise or lower  the discount rate to discourage or encourage borrowing by commercial  banks. By adjusting the reserve requirement (the minimum cash reserves  that banks must hold against their deposit liabilities), central banks con�  tract or expand the money supply. Their aim is to maintain conditions that  support a high level of employment and production and stable domestic  prices. Central banks also take part in cooperative international currency  arrangements designed to help stabilize or regulate the foreign exchange  rates of participating countries. Central banks have become varied in  authority, autonomy, functions, and instruments of action, but there has  been consistent increased emphasis on the interdependence of monetary  and other national economic policies, especially fiscal policies and debt  management policies.

The law limits its activi�  ties to foreign countries; it is prohibited from gathering intelligence on  U.S. soil, which is a responsibility of the Federal Bureau of Investigation.  Officially a part of the U.S. Defense Department, it is responsible for pre�  paring analyses for the National Security Council. Its budget is kept secret.  Though intelligence gathering is its chief occupation, the CIA has also  been involved in many covert operations, including the expulsion of  Mohammad Mosaddeq from Iran (1953), the attempted Bay of Pigs invasion  of Cuba (1961), and support of the Nicaraguan contras in the 1980s.</p><p>central limit theorem In statistics, any of several fundamental theo�  rems in probability. Originally known as the law of errors, in its classic  form it states that the sum of a set of independent random variables will  approach a normal distribution regardless of the distribution of the indi�  vidual variables themselves, given certain general conditions. Further, the  mean (see mean, median, and mode) of the normal distribution will coin�  cide with the (arithmetic) mean of the (statistical) means of each random  variable.</p><p>central nervous system See nervous system</p><p>Central Pacific Railroad U.S. railroad company founded in 1861 by  a group of California merchants including Mark Hopkins and Leland Stan-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Central Park &#x25BA; ceramics I 363</p><p>ford. It was built with land grants and subsidies from the Pacific Railway  Act (1862); thousands of Chinese labourers were hired to build it. Its  tracks joined with those of the Union Pacific on May 10, 1869, in Prom�  ontory, Utah, forming North America�s first transcontinental railroad.  From 1884 it was leased to the Southern Pacific Co., with which it merged  in 1959.</p><p>Central Park Public park, New York, New York, U.S. Located in Man�  hattan, it occupies an area of 840 acres (340 hectares). It was designed  by Frederick Law Olmsted and opened in 1876; it was artificially landscaped  to create an impression of wild and varied terrain. It includes footpaths  and bicycle paths, athletic fields, boating lakes, and a zoo. Free public  concerts and performances are frequent, notably the Shakespeare in the  Park series at an open-air theatre. The Metropolitan Museum of Art adjoins  the park.</p><p>Central Powers World War I coalition that was defeated by the Allied  Powers. Its primary members were the German empire and Austria-  Hungary, the �central� European states that were at war from August 1914  against France, Britain, and Russia. The Ottoman empire entered the war  on the side of the Central Powers in October 1914, followed by Bulgaria  in October 1915.</p><p>central processing unit See CPU</p><p>Central Treaty Organization (CENTO) originally Middle East  Treaty Organization or Baghdad Pact Organization Mutual-  security organization, originally composed of Turkey, Iran, Iraq, Pakistan,  and Britain. It was formed in 1955, at the urging of the U.S. and Britain,  to counter the threat of Soviet expansion into the Middle East. CENTO  was never very effective. Iraq withdrew after its anti-Soviet monarchy was  overthrown in 1959. In that same year the U.S. became an associate  member, and CENTO�s headquarters were moved to Ankara, Tur. After  the fall of Mohammad Reza Shah Pahlavi in 1979, Iran withdrew and  CENTO was dissolved.</p><p>Central Valley Spanish Valle Central \'ba-ya-sen-'tral\ Valley,  Chile. Located in central Chile between the Western Cordillera of the  Andes Mountains and the coastal range, it extends about 400 mi (650 km)  from the Chacabuco Range in the north to the Bio-Bio River in the south.  The agricultural heartland of Chile, it was the original centre of European  colonization beginning in the mid-1500s, and it continues to be home to  most Chileans. Santiago is at its northern end.</p><p>Central Valley Valley, California, U.S. Located between the Sierra  Nevada and the Coast Ranges, it is more than 400 mi (640 km) long and  20-50 mi (32-80 km) wide. The Sacramento and San Joaquin rivers,  which run through the valley, are fed by abundant rains and melting snows  of the Sierras. Because of the irrigation made possible by numerous dams  and canals, the area now contains some of the richest farmland in the U.S.</p><p>centrifugal \sen-'trif-y3-g3l\ force Fictitious force, peculiar to circu�  lar motion, that is equal but opposite to the centripetal force that keeps a  particle on a circular path (see centripetal acceleration). For example, a  stone attached to a string and whirling in a horizontal circular path is  accelerated toward the centre of its path by the tension in the string, the  only force acting on the string. However, in a reference frame at rest with  the stone, another force�the centrifugal force�must be introduced for  Newton's laws of motion to apply. Centrifugal force is a useful concept  in analyzing behaviour in rotating systems.</p><p>centrifugal \sen-'trif-y3-g9l\ pump Machine for moving liquids and  gases. Its two major parts are the impeller (a wheel with vanes) and the cir�  cular pump casing around it. In the most common type, called the volute  centrifugal pump, fluid enters the pump at high speed near the centre of the  rotating impeller and is thrown against the casing by the vanes. The cen�  trifugal pressure forces the fluid through an opening in the casing; this out�  let widens progressively in a spiral fashion, which reduces the speed of the  fluid and thereby increases pressure. Centrifugal pumps are used for many  purposes, such as pumping liquids for water supply, irrigation, and sewage  disposal systems. They are also used as gas compressors.</p><p>centrifuge Vsen-tro-.fyujV Machine that applies a sustained centrifugal  force. Effectively, the centrifuge substitutes a similar, stronger force for  that of gravity. Every centrifuge contains a spinning vessel; there are many  configurations, depending on use. A revolving object exerts a force away  from the centre of rotation (see Newton's laws of motion), called the cen�  trifugal force; it is usually stated as so many �times gravity� or so many</p><p>�G,� and may range from a few G for the basket in a home washing  machine or an industrial separator to hundreds of thousands of G for cen�  trifuges to separate isotopes of uranium or to purify vaccines.</p><p>centripetal \sen-'trip-3-t3l\ acceleration Property of the motion of  an object traveling in a circular path. Centripetal describes the force on  the object, directed toward the centre of the circle, which causes a con�  stant change in the object�s direction and thus its acceleration. The mag�  nitude of centripetal acceleration a is equal to the square of the object�s  velocity v along the curved path divided by the object�s distance r from  the centre of the circle, or a = v 2 /r.</p><p>centroid In geometry, the centre of mass of a two-dimensional figure  or three-dimensional solid. Thus the centroid of a two-dimensional fig�  ure represents the point at which it could be balanced if it were cut out  of, for example, sheet metal. The centroid of a circle or sphere is its cen�  tre. More generally, the centroid represents the point designated by the  mean (see mean, median, and mode) of the coordinates of all the points in  a set. If the boundary is irregular, finding the mean requires using calcu�  lus (the most general formula for the centroid involves an integral).</p><p>centromere Vsen-tro-.mhA Structure in a chromosome that holds  together the two chromatids. It is the point of attachment to the structure  that pulls the chromatids to opposite ends of the cell during cell division  (see mitosis). During the middle stage of mitosis, the centromere dupli�  cates and the chromatid pair separates, each chromatid becoming a sepa�  rate chromosome. Thus, when the cell divides, both daughter cells have  complete sets of chromosomes.</p><p>century plant or American aloe or maguey \m9-'ga\ Species of  AGAVE (Agave americana), of Mexico and the southwestern U.S. It takes  many years (from five to 100) to mature, flowers only once, and then dies.  It is widely cultivated for its large spiny leaves and enormous flower clus�  ter, and may reach 20 ft (6 m) in height. Century plants provide the dis�  tinctive ingredient for the alcoholic drinks pulque and mescal.</p><p>Cephalonia or Cephallenia Largest of the Ionian Islands, western  Greece. With Ithaca and smaller nearby islands, it forms the Kefallima  department. The mountainous island occupies 302 sq mi (781 sq km) and  rises to 5,341 ft (1,628 m) at Mount Amos. Argostolion, the chief town  and a port on the southwestern coast, is the department capital. The island  was an important Mycenaean centre, which the Romans seized in 189 bc.  In the Middle Ages it was captured by Robert Guiscard. Later it was ruled  by various Neapolitan and Venetian families. In 1809 it was taken by the  British, then ceded to Greece in 1864. It experienced a devastating earth�  quake in 1953.</p><p>cephalopod Vse-fo-lo-.padX Any marine mollusk of the class Cepha�  lopoda (e.g., cuttlefish, nautilus, octopus, and squid), which includes the  most active and largest living invertebrates. Cephalopods are bilaterally  symmetrical and typically have a highly developed centralized nervous  system. Their image-forming eyes are similar in structure to vertebrate  eyes, and their heads are armed with tentacles that have rows of round  suction disks. Most cephalopods can change skin colour to blend in with  their surroundings. All can swim, propelling themselves backward by  expelling water forcefully. Most are carnivores that feed on fish, crusta�  ceans, and other mollusks.</p><p>Cepheid \'sef-e-od\ variable One of a class of variable stars whose  period of variation is closely related to its luminosity and is therefore use�  ful in measuring the distances to clusters of stars and galaxies. Named for  the prototype of this class found in the constellation Cepheus, classical  Cepheids have periods from about 1.5 days to over 50 days and are Popu�  lation I stars (see Populations I and II). The longer the period of such a star,  the greater its natural brightness; this relationship was discovered in 1912  by the American astronomer Henrietta Leavitt (b. 1868�d. 1921).</p><p>Ceram or Seram Vsa-.rairA Island of the central Moluccas, Indonesia.  It has an area of 6,621 sq mi (17,148 sq km). The terrain is mountainous  and covered with tropical forests; seismic activity is common. Portuguese  missionaries arriving in the 15th century found Hindu and Islamic influ�  ences present; the island came under nominal Dutch control c. 1650. Dur�  ing World War II the Japanese occupied it; after the war it became part  of Indonesia.</p><p>ceramics Traditionally, objects created from such naturally occurring  raw materials as clay minerals and quartz sand, by shaping the material  and then hardening it by firing at high temperatures to make the object</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>364 I Ceratium &#x25BA; cerium</p><p>stronger, harder, and less permeable to fluids.

Mem�  bers are dinoflagellates with both plant and animal characteristics. The cell  is flattened horizontally and contains yellow, brown, or green pigments.  Ceratium species are covered by a theca, or armour, composed of many  textured plates that form one horn in the front and usually two in the back;  these horns slow the sinking of the organism. The body form varies  according to the salt content and temperature of the surrounding water:  the spines tend to be short and thick in cold, salty water and long and thin  in less salty, warmer water. Members form an important part of the plank�  ton found in northern seas.</p><p>Cerberus Vs9r-b3-r3s\ In Greek mythology, the monstrous watchdog of  the underworld. He was usually said to have three heads, though Hesiod  says he had 50. Heads of snakes grew from his back, and he had a ser�  pent�s tail. He devoured anyone who tried to escape Hades�s kingdom,  and he refused entrance to living humans, though Orpheus gained passage  by charming him with music. One of the labours of Heracles was to bring  Cerberus up to the land of the living; after succeeding, he returned the  creature to Hades.</p><p>cereal or grain Any grass yielding starchy seeds suitable for food. The  most commonly cultivated cereals are wheat, rice, rye, oats, barley, corn,  and sorghum. As human food, cereals are usually marketed in raw grain  form or as ingredients of food products. As animal feed, they are con�  sumed mainly by livestock and poultry, which are eventually rendered as  meat, dairy, and poultry products for human consumption. They also are  used industrially in the production of a wide range of substances, such as  glucose, adhesives, oils, and alcohols. Measured in acres planted, wheat  is the world�s most widely grown cereal crop; rice is the second, but more  com is harvested than either. Grains are generally rich in carbohydrates  and energy value but comparatively low in protein and naturally deficient  in calcium and vitamin A. Breads are usually enriched to compensate for  any nutritional deficiencies in the cereal used. Though often consumed in  the areas where grown, cereal and cereal by-products are also major com�  modities in international trade.</p><p>cereal Prepared foodstuff of cereal grain. Cereals are used for both  human and animal food. The first step in making cereal is milling, grind�  ing the grain so that it can be easily processed. Modem automated sys�  tems employ steel cylinders, followed by air purification and numerous  sievings to separate the endosperm from the outer coverings and the germ;  com is milled by wet processes. Cereal products include minimally pro�  cessed whole, crushed, or rolled grains, flour, cornstarch, meal (coarsely  ground and unsifted grain), and pasta. Breakfast cereals include raw cere�  als such as oatmeal and farina (which must be boiled), shredded cereals  (usually whole wheat that is boiled, dried, and cut), flaked cereals (usu�  ally corn that is broken down into grits and cooked under pressure with  flavoring syrup before being pressed and toasted), puffed cereals (grains  heated in a pressure chamber and then released to cause expansion), and  granular cereals (flour-based cereals made from dough that is cooked and  ground into small bits). All cereals are high in starch.</p><p>cerebellum V.ser-s-'bel-onrf Part of the brain that integrates sensory  input from the inner ear and from proprioceptors (see proprioception) in  muscle with nerve impulses from the cerebrum (see cerebral cortex), coor�  dinating muscle responses to maintain balance and produce smooth, coor�  dinated movements. Located below the cerebral hemispheres and behind  the upper medulla oblongata and pons, each of its two connected hemi�  spheres has a core of white matter within a cortex of gray matter. Dis�  orders usually produce neuromuscular disturbances, in particular ataxia.</p><p>cerebral cortex \s3-'re-brel, 'ser-o-brsH Layer of gray matter that con�  stitutes the outer layer of the cerebrum and is responsible for integrating sen�  sory impulses and for higher intellectual functions. It is divided into four  lobes, roughly defined by major surface folds; sometimes the limbic sys�  tem, or limbic lobe, is considered to be a fifth lobe. The frontal lobe controls  motor activity and speech, the parietal controls touch and position, and the  temporal lobe handles auditory reception and memory. The occipital lobe  at the back of the brain holds the brain�s major visual-reception area. The  limbic lobe controls smell, taste, and emotional responses.</p><p>cerebral palsy Paralysis resulting from abnormal development or  damage to the brain before or soon after birth. Cases are of four main</p><p>types: spastic, with spasms contracting the extremities, and often mental  retardation and epilepsy; athetoid, with slow, changing spasms in the face,  neck, and extremities, grimacing, and inarticulate speech (dysarthria);  ataxic, with poor coordination, muscle weakness, an unsteady gait, and  difficulty performing rapid or fine movements; and mixed, in which symp�  toms of two or more types are present.</p><p>cerebral seizures See epilepsy</p><p>cerebrospinal \s3- l re-bro-'spI-n a l\ fluid (CSF) Clear, colourless liq�  uid that surrounds the brain and spinal cord and fills the spaces in them. It  helps support the brain, acts as a lubricant, maintains pressure in the skull,  and cushions shocks. Analysis of CSF obtained by a spinal tap (lumbar  puncture) helps diagnose a number of disorders, including meningitis and  hemorrhage in the central nervous system.</p><p>cerebrum Nso-'re-brom, 'ser-a-bronrf Largest part of the brain. The two  cerebral hemispheres consist of an inner core of myelinated nerve fibres,  the white matter, and a heavily convoluted outer cortex of gray matter  (see cerebral cortex). Nerve fibres in the white matter connect functional  areas of the cortex in the same hemispheres, connect functional areas of  the cortex in opposite hemispheres, and connect the cerebral cortex to  lower centres (e.g., the spinal cord). A front-to-back fissure divides the  cerebrum�s two hemispheres. Each hemisphere controls the opposite side  of the body. The corpus callosum, a thick band of white matter, connects  them, allowing integration of sensory data and responses from both sides  of the body. Other important cerebral structures include the hypothalamus  and the thalamus.</p><p>Ceres Vsir-ez\ In Roman religion, the goddess of the growth of food  plants, sometimes worshiped in asso�  ciation with the earth goddess Tellus.</p><p>Her cult was overlaid by that of  Demeter, who was worshiped in  Greece and Sicily.

The genus Selenicereus  (night-blooming cereus, or moon  cactus), containing about 20 species, is known for its large, usually fra�  grant, night-blooming white flowers, among the largest in the cactus fam�  ily. The queen-of-the-night ( S . grandiflorus ), the best-known night�  blooming cereus, is often grown indoors.</p><p>Cerf VsorfV, Bennett (Alfred) (b. May 25, 1898, New York, N.Y.,  U.S.�d. Aug. 27, 1971, Mount Kisco, N.Y.) U.S. publisher and editor.  With Donald S. Klopfer, in 1925 Cerf acquired the Modem Library  imprint, which subsequently became a highly profitable series of reprints  of classic books. In 1927 they began publishing books other than Mod�  ern Library titles as Random House, of which Cerf served as president  (1927-65) and chairman (1965-70). He became known as an opponent  of censorship and as the publisher of many eminent authors. An inveter�  ate punster and raconteur, he edited anthologies of humour, short stories,  and plays, wrote syndicated newspaper columns, and appeared on the  popular television show �What�s My Line?� (1952-68).</p><p>cerium \'sir-e-am\ Chemical element, a rare earth metal of the lanthanide  series (hence having many properties of the transition elements), chemical  symbol Ce, atomic number 58.

Introduced in the early 1960s, CDs have become a popular  method of saving.</p><p>certiorari V.sor-sho-'rar-eX In law, a writ issued by a superior court for  the reexamination of an action of a lower court. The writ of certiorari was  originally a writ from England�s Court of Queen�s (King�s) Bench to the  judges of an inferior court; it was later expanded to include writs from the  equity (chancery) courts. In the U.S., certiorari is the most common means  by which cases from the United States Courts of Appeals are reviewed by  the Supreme Court of the United States. For the Supreme Court to issue a  writ of certiorari, at least four justices must agree to hear the case.</p><p>Cervantes \s9r-'van-,tez\ (Saavedra), Miguel de (b. Sept. 29?,  1547, Alcala de Henares, Spain�d. April 22, 1616, Madrid) Spanish  novelist, playwright, and poet, the most celebrated figure in Spanish lit�  erature. After studying in Madrid, Cervantes joined the Italian infantry,  fought the Turks at Lepanto, and was captured with his brother and sold  into slavery in Algiers for five years. Back in Spain, his chronic financial  problems and tangled affairs led to brushes with the law and brief impris�</p><p>onment. While in tedious civil-service employment, he wrote the pasto�  ral romance La Galatea (1585) and plays, poetry, and short stories, to  small success. His marvelous creation Don Quixote (1605, 1615), brought  immediate success and literary eminence, if not riches. It parodies chiv-  alric romances of the day with the comic adventures of a bemused eld�  erly knight who sets out on his old horse, Rosinante, with his pragmatic  squire, Sancho Panza. Often considered the first and certainly one of the  great novels, it has influenced many writers and inspired numerous cre�  ations in other genres and media. Cervantes also published a large set of  eight comedies and eight interludes for the stage (1615) and the romance  The Labors of Persiles and Sigismunda (1617).</p><p>cervical spondylosis \ l span-d3-'lo-s3s\ Degenerative disease of the  neck vertebrae. Compression of the spinal cord and cervical nerves by  narrowing of spaces between vertebrae causes radiating neck or arm pain  and stiffness, restricted head movement, headaches, spastic paralysis, and  arm and leg weakness. Cervical spondylosis can resemble neurological  disease with unrelated arthritis. It is treated with rest, traction, and pos�  sibly a cervical collar. Removal of herniated disks or fusion of vertebrae  may be necessary.</p><p>cervicitis N.ssr-vs-'sI-tssX Inflammation of the cervix of the uterus, caused  by infection or irritation. It is most common during the years of men�  struation. Cervicitis can be acute or chronic and may worsen during preg�  nancy. It does not cause pain but may lead to polyps. The major symptom  is an abundant discharge, which can impair fertility. Treatment may  include antibiotics or cauterization or surgery to repair or remove the cer�  vix; this does not affect fertility.</p><p>Cesaire \sa-'zer\, Aime (-Fernand) (b. June 25, 1913, Basse-Pointe,  Mart.) Martinican poet and playwright. Educated in Paris, Cesaire  returned to Martinique to be elected to the National Assembly as a Com�  munist. A cofounder with Leopold Senghor of the Negritude movement, he  ardently supported the decolonization of French colonies of Africa, a view  expressed in the fiery poems of Return to My Native Land (1939) and  Soleil cou-coupe (1948, �Sun�s Slashed Throat�). Discarding Negritude  for black militancy, he turned to the theatre and wrote the political dra�  mas The Tragedy of King Christophe (1963) and A Season in the Congo</p><p>(1966).</p><p>cesarean section \si-'zar-e-9n\ or C-section Surgical removal of a  fetus from the uterus through an abdominal incision at or before full term.  It is usually performed when vaginal delivery would endanger the life or  health of the mother or the child. Vaginal delivery is often possible in  subsequent pregnancies. Cesarean section carries the usual risks of major  surgery. Once overused, largely for fear of malpractice suits, its use has  been greatly reduced by the natural childbirth movement.</p><p>cesium Vse-ze-9m\ Chemical element, one of the alkali metals, chemical  symbol Cs, atomic number 55. The first element discovered by spectros�  copy (1860), it is silvery white, liquid at warm room temperature (melt�  ing at 83 �F [28.4 �C]), and very soft when solid. About half as abundant  as lead, it occurs in minute quantities as ores. It reacts explosively with  cold water and is used to scavenge traces of oxygen and other gases in  electron tubes. Other uses are as a catalyst and in photoelectric cells, ion  propulsion systems, atomic clocks, and plasma for thermoelectric conver�  sion. Cesium salts have various specialty applications, including in min�  eral waters.</p><p>Cespedes \'sas-pa-,thas\ (y Borja del Castillo), Carlos Manuel</p><p>de (b. April 18, 1819, Bayamo, Cuba�d.

A military station and seaport, it constitutes  with Meulia an autonomous community of Spain with an area of 8 sq mi  (20 sq km). The city is on a narrow isthmus that connects Jebel Musa  (one of the Pillars of Hercules) to the mainland. Located in northern  Morocco at the eastern end of the Strait of Gibraltar, it was successively  colonized by Carthaginians, Greeks, and Romans. Long a flourishing trad�  ing town, it was taken by the Portuguese in 1415, and it passed to Spain  in 1580.

Oct. 22, 1906, Aix-en-  Provence) French painter, one of the  founders of modem painting. In  1859 he entered law school; in 1861  he left to study art in Paris. Critics  denounced the works he exhibited at  the Salon des Refuses (1863), but he  persevered. He became associated  with the Impressionists, exhibiting  with them in 1874 and 1877. Unlike  the other artists in the group, he  emphasized the structure of objects  rather than the vision presented by  the light that emanated from them,  basing his compositions on cubic  masses, patches of colour, and archi�  tectonic lines. By the late 1870s he  had broken with the Impressionists,  exploring his own radically new way  of simultaneously depicting deep  space and flat design; his later work  is therefore often classified as �Post-  Impressionist.� From 1890 to 1905 he produced masterpieces, one after  another: variations of the Mont Sainte-Victoire landscape, three versions  of Boy in a Red Waist-Coat, countless still-life images, and the Bathers  series of nudes. Public reception to his first one-man exhibition (1895)  was cool, but he slowly gained acceptance. His work was a major source  of inspiration for the Cubists Georges Braque and Pablo Picasso.

In  1827-31 he wrote in French his Philosophical Letters, which explored  among other issues Russia�s relation to the West; he urged a Western path  of development for Russia. After a Russian translation of the first letter  appeared, it was banned, and Chaadayev was declared insane.

The lowest  elevation, 573 ft (175 m), is in the Djourab Depression. Chad�s river net�  work is limited to the Chari and Logone rivers and their tributaries, which  flow from the southeast into Lake Chad. The economy is agricultural;  gold, uranium, and petroleum reserves have not been fully exploited. Chad  is a republic with one legislative body; its chief of state is the president,  its head of government the prime minister. About ad 800 the kingdom of  Kanem was founded, and by the early 1200s its borders had expanded to  form a new kingdom, Kanem-Bornu, in the north. Its power peaked in the  16th century with its command of the southern terminus of the trans-  Sahara trade route to Tripoli. About this time the rival kingdoms of Bagu-  irmi and Ouaddai (Wadai) evolved in the south. In the years 1883-93 all  three kingdoms fell to the Sudanese adventurer Rabih al-Zubayr, who was  overthrown in 1900 by a local ruler under French protection. Extending  their power, the French in 1910 made Chad a part of French Equatorial  Africa, and it was made an overseas territory in 1946. The country  achieved independence in 1960 but has had decades of civil war despite  frequent intervention by France and Libya, resulting in political instabil�  ity and a lack of economic development.</p><p>Chad, Lake Lake, west-central Africa.

After studying paint�  ing in St. Petersburg, he moved to Paris in 1910. During the next four  years he mixed with the avant-garde there and created what is often con�  sidered his best work in the style he would explore for the next 60 years.  Often the principal figure in his fantastical works is the painter himself,  and memories of Jewish life and folklore in Belarus and themes from the  Bible are main sources of imagery. The often whimsical figurative ele�  ments in his works are frequently depicted upside down and distributed  on the canvas in an arbitrary fashion. In the 1920s he launched a career  in printmaking, producing hundreds of etchings for special editions of  books. In 1941 he left for New York City, where he designed sets and  costumes for Igor Stravinsky�s ballet The Firebird. He later produced  stained-glass windows and murals for public buildings in Jerusalem, Paris,  and the U.S.</p><p>Chagos Archipelago Ycha-gssX Island group, central Indian Ocean.

By the Norman Conquest (1066), the coat was long and fully sleeved; a  hood, usually fitting under a helmet, covered the head and neck. By the  12th century, mail was fitted to hands, feet, and legs. The addition of plates  to increase chest and back protection gradually evolved in the 14th cen�  tury into complete plate armour, displacing mail.</p><p>chain reaction Process yielding products that initiate further processes  of the same kind. Nuclear chain reactions are a series of nuclear fissions  initiated by neutrons produced in a preceding fission. A critical mass, large  enough to allow more than one fission-produced neutron to be captured,  is necessary for the chain reaction to be self-sustaining. Uncontrolled  chain reactions, as in an atomic bomb, occur when large numbers of neu�  trons are present and the reactions multiply very quickly. Nuclear reac�  tors control their reactions through the careful distribution of the  fissionable material and insertion of neutron-absorbing materials.</p><p>chain silicate See inosilicate</p><p>chair Seat, usually with four legs and a back, intended for one person.

Traditionally intended for perfor�  mance in a room or reception hall, often solely for the performers� own  pleasure, chamber music is now often heard in concert halls. It began with  the 16th-century instrumental consort, and long continued to be associ�  ated with aristocratic households. The duo sonata (usually for violin and  continuo) and trio sonata appeared in early 17th-century Italy. The string  quartet arose in the 1750s and remains the best-known chamber genre  and ensemble. The serenade, nocturne, and divertimento were Classical  genres for varying instrumental forces, often intended to accompany  meals and other activities. Standard ensembles include the string trio  (violin, viola, cello), string quintet (two violins, two violas, cello), and  piano trio (piano, violin, cello). The chamber orchestra, usually with fewer  than 25 musicians, is often used for 18th-century music and usually  requires a conductor.

The International Chamber of Commerce  (founded 1920) acts as the voice of the business community in the inter�  national field and runs a court of arbitration for settling commercial dis�  putes. National chambers of commerce exist in most industrialized, free-  enterprise countries.

An admirer of Richard Wagner, he wrote a biography  of the composer and several books on his works (1892-95) and later mar�  ried Wagner�s daughter. In his Foundations of the Nineteenth Century (2  vol., 1899), he presented a broad but biased analysis of European culture  and proclaimed the racial and cultural superiority of the so-called Aryan</p><p>element in European culture. His theories, which owed much to the writ�  ings of Joseph Arthur, count de Gobineau, influenced German nationalist  thought, particularly Adolf Hitler�s National Socialist movement.</p><p>Chamberlain Vcham-bsr-linV, John (Angus) (b.

In 1957 he had his first  one-man exhibition in Chicago. His Abstract Expressionist sculptures are  often constructed of fragments of automobiles, crushed and jammed  together, and painted in bright, industrial colours; these produce an effect of  isolated, frozen movement. He also exhibited paintings, prints, and films.</p><p>Chamberlain, Joseph (b. July 8, 1836, London, Eng.�d. July 2,  1914, London) British politician and  reformer. Early success in business  enabled him to retire at age 38 with  a substantial fortune. He was elected  to Parliament (1876-1906), where he  became a leader of the left wing of  the Liberal Party. In 1886, in oppo�  sition to Irish Home Rule, he joined  other dissident Liberals (Liberal  Unionists) to defeat the Liberal gov�  ernment. He used his control of the  Liberal Unionists to pressure the  subsequent Conservative govern�  ment to adopt a more progressive  social policy. As colonial secretary  (1895-1903), he advocated tax  reform and a federated empire of  self-governing colonies, helping  pass the Commonwealth of Australia  bill (1900). He resigned when his  proposals for a tariff giving prefer�  ence to imperial products were  rebuffed by the government.</p><p>Chamberlain, (Arthur) Nev�  ille (b.

Son of Joseph Chamberlain  and half brother of Austen Chamberlain, he prospered in the metalworking  industry in Birmingham; as the city�s lord mayor (1915-16) he organized  England�s first municipal bank. He was a member of the House of Com�  mons (1918�40), during which he served in Conservative governments as  minister of health and chancellor of the Exchequer. As prime minister  (1937-40), he sought to prevent the outbreak of a general European war  over Adolf Hitler�s demand that Czechoslovakia cede the Sudetenland to  Germany. In 1938 he and France�s Edouard Daladier granted most of Hit�  ler�s demands in the Munich agreement, after which he returned to England  a popular hero, speaking of �peace in our time.� He repudiated appeasement  after Hitler seized the rest of Czechoslovakia, and when Germany attacked  Poland, he declared war. He lost the support of many Conservatives after  the failure of a British expedition to Norway and resigned in 1940.</p><p>Chamberlain, Wilt(on Norman) (b. Aug. 21, 1936, Philadelphia,  Pa., U.S.�d.

Conflicts between the counts of Champagne and the kings of France ended  with the marriage (1286) of Joan of Navarra and Champagne to King Philip  IV of France, and Champagne was united with the French crown in 1314.  As a frontier region, it was frequently invaded; it was the site of fierce  battles in World Wars I and II. The region is famous for its wines.</p><p>champagne Sparkling wine. Named for the site of its origin, the Cham�  pagne region of northeastern France, it is made from only three grapes:  pinot and meunier (both black) and chardonnay (white). The juice from  these grapes is initially fermented in stainless-steel vats. A mixture of  wine, sugar, and yeast is added, and it is then transferred to pressure tanks  for a second fermentation that yields carbon dioxide and effervescence.

Under the Qing dynasty, from 1664, it was the capital of Hunan  province, and it was a major rice market. It was besieged during the Tap�  ing Rebellion but never fell. Changsha was the site of Mao Zedong�s con�  version to communism. It was the scene of major battles in the Sino-  Japanese War of 1937-45 and was briefly occupied by the Japanese.  Rebuilt since 1949, the city is now a major port and a commercial and  industrial centre.</p><p>Channel, The See English Channel</p><p>Channel Islands or Santa Barbara Islands Chain of islands,  southern California, U.S. Extending 150 mi (240 km) along and 12-70  mi (20-115 km) off the coast, it is divided into the Santa Barbara group  (San Miguel, Santa Rosa, Santa Cruz, and Anacapa) and the Santa Cat�  alina group (Santa Barbara, San Nicolas, Santa Catalina, and San Clem�  ente). The islands range in size from Santa Cruz (98 sq mi [254 sq km])  to the small Anacapa islets. Rugged and mountainous, they are frequented  by colonies of sea lions, seals, and birds and are noted for their distinc�  tive plant life (several hundred varieties). The larger islands support sheep  and cattle ranches, and Santa Catalina is a noted resort. Channel Islands  National Park (established as a national monument in 1938) embraces  Anacapa, San Miguel, Santa Barbara, Santa Cruz, and Santa Rosa.</p><p>Channel Islands Island dependencies, United Kingdom. Located in  the English Channel 10-30 mi (16-48 km) off the western coast of France,  they cover an area of 75 sq mi (194 sq km) and include the islands of  Jersey, Guernsey, Alderney, and Sark and several islets. They are domes�  tically independent of the British government. Structures, including men�  hirs, are evidence of prehistoric occupation. A part of Normandy in the  10th century ad, the islands came under British rule at the time of the  Norman Conquest in 1066. The islets of Ecrehous and Les Minquiers were  disputed between England and France until 1953, when the International  Court of Justice confirmed British sovereignty. The dispute revived in the  late 20th century because sovereignty determines the rights to the conti�  nental shelf�s economic development (especially petroleum). The Chan�  nel Islands were the only British territory occupied by Germany in World  War II. The islands are famous for their cattle breeds, including the Jer�  sey and Guernsey.</p><p>Channel Tunnel or Eurotunnel Rail tunnel that runs beneath the  English Channel between Folkestone, England, and Sangatte (near Cal�  ais), France. A rail tunnel was chosen over proposals for a very long sus�  pension bridge, a bridge-and-tunnel link, and a combined rail-and-road  link. The 31-mi (50-km) tunnel, which opened in 1994, consists of three  separate tunnels, two for rail traffic and a central tunnel for services and  security. Trains, which carry motor vehicles as well as passengers, can  travel through the tunnel at speeds as high as 100 mph (160 kph).</p><p>Charming, William Ellery (b. April 7, 1780, Newport, R.I., U.S.�d.  Oct. 2, 1842, Bennington, Vt.) U.S. Unitarian clergyman. He studied the�  ology at Harvard University and became a successful preacher. From 1803  until his death he was pastor of Boston�s Federal Street Church. He began  his career as a Congregationaust but gradually adopted liberal and ratio�  nalist views that came to be labeled Unitarian. In 1820 he established a  conference of liberal Congregationalist clergy, later reorganized as the  American Unitarian Association. Known as the �apostle of Unitarianism,�  he also became a leading figure in New England Transcendentalism, and  his lectures and essays on slavery, war, and poverty made him one of the  most influential clergymen of his day.</p><p>chanson \sha n -�so n \ French "song" French art song.

More than 80  chansons de geste have survived in 12th- to 15th-century manuscripts.  Dealing chiefly with events of the 8th-9th century, they contain a core of  historical truth overlain with legend. Most are anonymous. The Chanson  de Roland was the formative influence on later chansons de geste, which  in turn influenced literature throughout Europe.</p><p>Chanson de Roland \sha n -'s6 n -d9-r6-'la n \ English "Song of  Roland" Old French epic poem written c. 1100, the masterpiece and  probably the earliest of the chanson de geste form. Its probable author was  a Norman, Turold (Turoldus), whose name is introduced in its last line.  It deals with the Battle of Roncesvalles (778), a skirmish against the  Basques that the poem portrays as a heroic battle against the Saracens.  Direct and sober in style, it highlights a clash between the recklessly cou�  rageous Roland and his prudent friend Oliver, which is also a conflict  between divergent conceptions of feudal loyalty.</p><p>chant See Byzantine chant, Gregorian chant</p><p>chanterelle \,shan-t9-'rel\ Highly prized, fragrant, edible mushroom  (Cantharellus cibarius, order Polyporales), rich yellow in colour, found  in woods in summer and autumn.

The silk laces that  made the town famous date from the  18th century. Black, white, and blond  lace (derived from natural silk) were  made in the 19th century, and by  1840 machine-made imitations were  available. The designs are character�  ized by naturalistic flowers and rib�  bons on a spotted background.</p><p>Chantilly porcelain Either of  two types of soft-paste porcelain  produced from c. 1725 to c. 1800 at  Chantilly, France. In the first type,  made until c. 1750, an opaque, milk-  white tin glaze was applied to a yel�  lowish ground; the designs were  simplified Japanese patterns. In the  second type (c. 1750-1800), a tradi�  tional transparent lead glaze was  applied over a coloured ground; the  designs were influenced by Meissen  and Sevres porcelain. Production  consisted primarily of domestic ware  (plates, basins, jugs) with painted  decoration in a limited palette. The  motifs were often small flower bou�  quets, known as Chantilly sprigs, or  scrolls and plaits.</p><p>Chao Phraya River \chau-'pri-  o\ or Maenam River \ma-'nam\</p><p>River, Thailand. Flowing south from  the highlands on the country�s north�  ern border to the head of the Gulf of  Thailand near Bangkok, it is some  225 mi (365 km) long and is Thai�  land�s principal river. It is important  for the transport of the country�s  exports. It also forms a highly pro�  ductive agricultural valley. The name  strictly applies only to the river�s  lower course, which begins at the  confluence of the Nan and Ping riv�  ers and is 140 mi (225 km) long.</p><p>Chaos \'ka-,as\ In Greek cosmology, either the primeval emptiness  before things came into being or the abyss of Tartarus, the underworld.  In Hesiod�s Theogony, there was first Chaos, then Gaea and Eros. The off�  spring of Chaos were Erebus (Darkness) and Nyx (Night). Ovid gave  Chaos its modern meaning: the original formless and disordered mass  from which the ordered universe is created. The early church fathers  applied this interpretation to the creation story in Genesis.</p><p>chaos theory \'ka-,as\ Mathematical theory that describes chaotic  behavior in a complex system. Applications include the study of turbulent  flow in fluids, irregularities in biological systems, population dynamics,  chemical reactions, plasma physics, meteorology, the motions of groups  and clusters of stars, transportation dynamics, and many other fields.</p><p>chaotic behaviour Behaviour in a complex system that appears  irregular or unpredictable but is actually determinate. The apparently ran�  dom or unpredictable behaviour in systems governed by complicated  (nonlinear) deterministic laws is the result of high sensitivity to initial  conditions. For example, Edward Lorenz discovered that a simple model  of heat convection exhibits chaotic behaviour. In a now-classic example  of such sensitivity to initial conditions, he suggested that the mere flap�  ping of a butterfly�s wings could eventually result in large-scale changes  in the weather (the �butterfly effect�).</p><p>Chapala \cha-'pa-la\, Lake Lake, Jalisco state, Mexico. Mexico�s larg�  est lake, it is about 50 mi (80 km) long and 10 mi (15 km) wide and has  an area of roughly 400 sq mi (1,000 sq km). A popular resort area, it is  both fed and drained by the Lerma River.</p><p>chaparral N.sha-po-'ralX Vegetation composed of broad-leaved ever�  green shrubs, bushes, and small trees, often forming dense thickets. Chap�  arral is found in regions with a Mediterranean climate, characterized by  hot, dry summers and mild, wet winters. The name is applied mainly to  the coastal and inland mountain vegetation of southwestern North  America. Chaparral vegetation becomes extremely dry by late summer.  The fires that commonly occur during this period are necessary for the  germination of many shrub seeds, and they clear away dense ground  cover, thus maintaining the shrubby growth form of the vegetation by  preventing the spread of trees. New chaparral growth provides good graz�  ing for domestic livestock, and chaparral vegetation also is valuable for  watershed protection in areas with steep, easily eroded slopes.</p><p>chaparral cock See roadrunner</p><p>Chaplin, Charlie in full Sir Charles Spencer Chaplin (b. April  16, 1889, London, Eng.�d. Dec. 25, 1977, Corsier-sur-Vevey, Switz.)  British-U.S. actor and director. The son of poverty-stricken music-hall  entertainers, he became a vaudeville performer at age eight. On tour in  New York (1913), he caught the eye of Mack Sennett, who signed him to  a film contract. While making his second film, Kid Auto Races at Venice  (1914), Chaplin developed the costume�baggy pants, derby hat, over�  sized shoes, and cane�that was to become the hallmark of his famous  �little tramp� character. He was soon directing his own films, and he  became an instant star in The Tramp (1915). After cofounding United Art�  ists in 1919, he produced, directed, and starred in such classics as The  Gold Rush (1925), City Lights (1931), Modern Times (1936), The Great  Dictator (1940), Monsieur Verdoux (1947), and Limelight (1952).  Harassed for his leftist political views, he moved to Switzerland in 1952.  In 1972 he returned to the U.S. to accept a special Academy Award.</p><p>Chapman, Frank Michler (b.

He began his career at the American Museum of Natural History in 1887  and was curator of ornithology in 1908^42; his exhibits were some of the  first to display birds in naturalistic settings. He founded and edited (1899�  1935) the magazine Bird-Lore. Among his many important works are  Handbook of Birds of Eastern North America (1895) and several on South  American birds.</p><p>Chapman, Maria Weston orig. Maria Weston (b.

The hill was captured by a U.S. assault (1847) in the  Mexican War. In the 1860s Mexico�s Emperor Maximilian rebuilt the castle;  it remained the official residence of Mexican presidents until 1940, when  it was converted into a museum.</p><p>char Any of several freshwater food and game fishes (genus Salvelinus)  of the salmon family, distinguished from the similar trout by light, rather  than black, spots; by a boat-shaped, rather than flat, vomer (bone) on the  roof of the mouth; and by having teeth on the front of the vomer rather  than on the shaft. Char often have smaller scales than their relatives. The  Arctic char, of North America and Europe, inhabits the Arctic and adja�  cent oceans and enters rivers and lakes to breed.

In 1882 he opened Europe�s greatest neurological  clinic of the day. An extraordinary teacher, he was known for his work  with hysteria and hypnosis, which influenced many students, including  Sigmund Freud. He described the symptoms of locomotor ataxia and the  disintegration of ligaments and joint surfaces it causes (Charcot disease,  Charcot joint), pioneered the linking of brain sites with specific functions,  and discovered miliary aneurysms in the brain.</p><p>chard or Swiss chard Edible-leaf beet {Beta vulgaris, variety cicla ),  a variety of beet in which the tender  leaves and leafstalks have become  greatly developed.

He  became known as a successful  painter of still lifes and domestic  scenes that were remarkable for their  intimate realism, tranquil atmo�  sphere, and luminosity. In his later  years he produced stunning pastel  portraits. He was the greatest still-life painter of the 18th century, well  known in his lifetime through engravings of his work. The meditative  quiet of his work contrasts with the spirit of light and superficial bril�  liance seen in the work of many of his contemporaries. Many 20th-century  artists were inspired by the abstract qualities of his compositions.</p><p>Charente River \sha-'raiit\ River, western France.

April 2, c. 742�d. Jan. 28, 814, Aachen, Austrasia)  King of the Franks (768-814) and emperor (800-14). The elder son of the  Frankish king Pippin III (the Short), he ruled the Frankish kingdom jointly  with his brother Carloman until the latter�s death in 771. He then became  sole king of the Franks and began a series of campaigns to conquer and  Christianize neighbouring kingdoms. He defeated and became king of the  Lombards in northern Italy (774). His expedition against the Muslims in  Spain failed (778), but he successfully annexed Bavaria (788). Charle�  magne fought against the Saxons for many years, finally defeating and  Christianizing them in 804. He subdued the Avars of the Danube and  gained control of many of the Slav states. With the exception of the Brit�  ish Isles, southern Italy, and part of Spain, he united in one vast state  almost all the Christian lands of western Europe. His coronation as  emperor at Rome on Christmas Day, 800, after restoring Leo III to the  papacy, marks the revival of the empire in Latin Europe and was the fore�  runner of the Holy Roman Empire. Charlemagne established his capital at  Aachen (Aix-la-Chapelle), where he built a magnificent palace. He invited  many scholars and poets to assist him in the promotion of the religious  and cultural revival known as the Carolingian renaissance. He also cod-  ifed the laws and increased the use of writing in government and society.  He was succeeded on his death by his son Louis the Pious, whom Char�  lemagne had crowned coemperor in 813.

It  was strategically important in the 17th�19th centuries and was held vari�  ously by France, Spain, Austria, and Holland. Though the fortress was dis�  mantled in the late 19th century, the area retained its strategic importance;  it was the scene of one of the first battles of World War I.</p><p>Charles (Philip Arthur George), prince of Wales (b.

He took a tour of duty  with the Royal Navy (1971-76). In 1981 he married Lady Diana Spen�  cer (see Diana, princess of Wales), and they had two sons, William and  Henry. Their marriage grew strained amid intense scrutiny from the press  and rumours of infidelity; they divorced in 1996.

By age 7 he  had completely lost his sight. He learned to write scores in Braille.  Orphaned at 15, he left school to play professionally. He recorded �Mess  Around� and �It Should�ve Been Me� in 1952-53, and his arrangement  for Guitar Slim�s �The Things That I Used to Do� became a million-seller.  Combining blues and gospel music influences, a distinctive raspy voice, and  liquid phrasing, Charles later had hits with �What�d I Say,� �Georgia on  My Mind,� and �Hit the Road, Jack.� His Modern Sounds in Country and  Western Music (1962), marking unusual territory for a black performer,  sold more than a million copies.

He became heir presumptive to the Hab-  sburg throne on the assassination of his uncle, Francis Ferdinand. After he  succeeded Francis Joseph in 1916, he made several abortive attempts to  take Austria-Hungary out of World War I. He renounced participation in  affairs of state in 1918 and was deposed in 1919. After two failed attempts  to regain his Hungarian throne in 1921, he was sent into exile in Madeira,  where he died.</p><p>Charles I (b. Nov. 19, 1600, Dunfermline Palace, Fife, Scot.�d. Jan.  30, 1649, London, Eng.) King of Great Britain and Ireland (1625^-9).  Son of James I, he acquired from his father a belief in the divine right of  kings, and his earliest surviving letters reveal a distrust of the House of  Commons. He became king in 1625 and soon after married Henrietta  Maria. He came into conflict with his first Parliament because of religious  issues, his war against Spain, and the general distrust of his adviser the  1st duke of Buckingham. After dissolving several successive Parliaments,  Charles ruled his kingdom for 11 years without calling a Parliament.  Among the measures he took to be independent of parliamentary grants  was the levying of ship money. In 1639 he went to war against Scotland,  and the need to raise money prompted him to summon what came to be  known as the Short Parliament and the Long Parliament. Eventually his  authoritarian rule and quarrels with Parliament provoked the English Civil  Wars. After his forces were defeated in the second of these wars, the army  demanded that he stand trial for treason as �the grand author of our  troubles.� In 1649 he was convicted and executed, and Oliver Cromwell  proclaimed the Commonwealth.</p><p>Charles I Hungarian Karoly known as Charles Robert of Anjou</p><p>Van-jii\ (b. 1288, Naples, Kingdom of Naples�d. July 16, 1342, Viseg-  ard, Hung.) King of Hungary (1301, 1308�42). He claimed the Hungar�  ian throne with papal approval and was crowned in 1301, but his claim  was disputed, and he was not recognized as king until 1308. A courtly and  pious ruler, Charles restored Hungary to the status of a great power. An  alliance with Poland enabled him to defeat the Holy Roman emperor and  the Austrians. He failed to unite Hungary and Naples but negotiated a  pact providing that his eldest son would become king of Poland.</p><p>Charles I known as Charles of Anjou \'an-ju\ (b. March 1226�d.  Jan. 7, 1285, Foggia, Kingdom of Naples [Italy]) King of Naples and Sic�  ily (1266-85), the first of the Angevin dynasty. The younger brother of  Louis IX of France, Charles allied with the papacy and conquered Naples  and Sicily in the 1260s, defeating the last representatives of the Hohen-  staufen dynasty. He created a great but short-lived Mediterranean empire,  expanding into the Balkans and becoming heir to the kingdom of Jerus�  alem (1277). The Sicilians rebelled against French domination in 1282  (see Sicilian Vespers) and drove out the Angevins in 1284. Charles died  while preparing a counteroffensive, and his kingdom was eventually  secured by the Spanish.</p><p>Charles II (b. May 29, 1630, London, Eng.�d. Feb. 6, 1685, London)  King of Great Britain and Ireland (1660-85). Son of Charles I and Hen�  rietta Maria, he supported his father in the English Civil Wars. After his  father�s execution, he invaded England in 1651 but was defeated at  Worcester. He then spent years in exile until Oliver Cromwell died and  conditions favored a return to the monarchy. His Declaration of Breda  paved the way for him to be proclaimed king in May 1660 (see Resto�  ration). He became known as �the Merry Monarch� for his lifting of Puri�</p><p>tan restrictions on entertainment and his own love of pleasure; his best-  known mistress was the actress Nell Gwyn. Important events of his reign  included the controversial Treaty of Dover and two wars with the Dutch  (see Anglo-Dutch Wars). By the 1670s the miscarriages of his queen,  Catherine of Braganza, had reduced hopes that he would have a legitimate  heir (though he left at least 14 illegitimate offspring). He almost lost con�  trol of his government when hysteria arose over the Popish Plot to replace  him with his Roman Catholic brother James (the future James II). Charles  kept his nerve, reestablished his political control, and eventually enjoyed  a resurgence in loyalty. His political adaptability and acumen enabled him  to steer his country through the struggle between Anglicans, Catholics,  and dissenters that marked his reign.</p><p>Charles II known as Charles of Anjou \'an-ju\ or Charles the  Lame (b. c. 1254�d. May 5, 1309, Naples) King of Naples and ruler  of several other European territories. He guarded Naples while his father,  Charles I, launched a campaign to regain Sicily from the Aragonese. He  was captured and imprisoned (1284-88); on being freed he promised to  give up his claim to Sicily, but the pope released him from the vow, and  he fought unsuccessfully for Sicily until 1302. He built alliances through  the marriages of his children and extended his control over Piedmont,  Provence, Hungary, Athens, and Albania.</p><p>Charles II Spanish Carlos (b. Nov. 6, 1661, Madrid, Spain�d. Nov.  1, 1700, Madrid) King of Spain (1665-1700), the last monarch of the  Spanish Habsburg dynasty. Son of Philip IV and Maria Anna of Austria, he  was slow-witted and became known as Charles the Mad. His reign opened  with a 10-year regency under the queen mother. The first phase of his  personal government was concerned with resistance to the French impe�  rialism of Louis XIV, and the second was dominated by the succession  problem, for it was clear that he would father no children. His death led  to the War of the Spanish Succession.</p><p>Charles II known as Charles the Bad (b. 1332�d. Jan. 1, 1387)  King of Navarra (1349-87). He acquired Normandy from John II of France  by threatening an English alliance. Arrested for his treachery in 1356, he  escaped a year later and regained Normandy. He pursued shifting alli�  ances in Spain in an effort to expand Navarrese power. Charles V voided  his claims in France, and the discovery of his plot to poison the French  king cost him all of Normandy except Cherbourg.</p><p>Charles II known as Charles the Bald (b. June 13, 823�d. Oct. 6,  877, Brides-les-Bain, Fr.) Carolingian king (843-77) and emperor (875-  77). He was the son of the emperor Louis I and his second wife Judith.  Louis�s efforts to include Charles in the succession led to revolts against  the emperor by his three older sons. After the death of Louis, Charles  fought his two surviving half brothers in a bloody civil war (840^43) that  was concluded with the Treaty of Verdun, which settled the terms of suc�  cession. Charles was granted the kingdom of the western Franks, which  he ruled with the support of the bishops despite the wavering loyalties of  his vassals and the attacks of Norsemen, Bretons, and Germans. In 864  he won control of Aquitaine, and in 870 he gained western Lorraine. He  was crowned emperor in 875 but died two years later in the midst of inva�  sion and internal revolt. Inspired by his grandfather, Charlemagne, Charles  was a patron of the arts and oversaw the revival of the splendours of the  Carolingian renaissance.</p><p>Charles III known as Charles the Simple (b. Sept. 17, 879�d. Oct.  7, 929, Peronne, France) King of France (893-922). In 911 he ceded ter�  ritory by treaty, in the area later known as Normandy, to the Vikings, to  end their raids; their descendants became the Normans. The magnates of  Lorraine (Lotharingia) accepted Charles�s authority on the death of their  last Carolingian king. His preoccupation with Lotharingian affairs alien�  ated the French nobles, and in 922 they elected Robert I king in his stead.</p><p>Charles III Spanish Carlos (b. Jan. 20, 1716, Madrid, Spain�d. Dec.  14, 1788, Madrid) King of Spain (1759-88). Son of Philip V and Isabella  Farnese, he was duke of Parma (1732-34) and king of Naples (as Charles  VII, 1734-59) before becoming king of Spain. He was convinced of his  mission to reform Spain and make it once more a first-rate power, but his  foreign policy was not successful; Spain�s losses in the Seven Years' War  revealed naval and military weakness. He was more successful in  strengthening his own empire; during his reign Spain undertook commer�  cial reforms, made territorial adjustments in the interest of defense, and  introduced a modern administrative system. One of the enlightened des�  pots of the 18th century, he helped lead Spain to a brief cultural and eco�  nomic revival.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>376 I Charles III &#x25BA; Charles X Gustav</p><p>Charles III known as Charles the Fat (b. 839, Bavaria?  [Germany]�d. Jan. 13, 888, Neidingen) Frankish king and emperor (881�  87). The great-grandson of Charlemagne, he inherited the kingdoms of  Swabia (876) and Italy (879). Charles was crowned emperor by the pope  in 881. He gained control of the eastern and western Frankish kingdoms  on the deaths of their rulers, and by 885 he had reunited all of Charle�  magne�s empire except Provence. Chronically ill, he failed to attack the  Saracens and used tribute to buy off Viking invaders. His nephew Arnulf  led an uprising against him in 887, and his fall marked the final disinte�  gration of the empire of Charlemagne.</p><p>Charles IV known as Charles the Fair (b. 1294�d. Feb. 1, 1328,  Vincennes, Fr.) King of France and of Navarre (as Charles I) 1322-28.  The last of the direct line of the Capetian dynasty, he took the throne on  the death of his brother Philip V. His intrigues aimed at gaining the Ger�  man throne and annexing Flanders were unsuccessful. He renewed war  with England by invading Aquitaine and won a generous settlement in the  peace of 1327.</p><p>Charles IV orig. Wenceslas known as Charles of Luxembourg</p><p>(b. May 14, 1316, Prague�d. Nov. 29, 1378, Prague) King of the Ger�  mans and of Bohemia (1346-78) and Holy Roman emperor (1355-78).  Charles was elected German king in place of Louis IV in 1346. That same  year his father died in a war against England, and Charles became king  of Bohemia. He invaded Italy and won the crown of Lombardy as well  as the imperial crown at Rome. Charles enlarged his dynastic power  through skillful diplomacy and made Prague the political and cultural  center of the empire. He issued the Golden Bull of 1356 and won the  right of succession to the German throne for his son Wenceslas.</p><p>Charles IV Spanish Carlos (b. Nov. 11, 1748, Portici, Kingdom of  Naples�d. Jan. 20, 1819, Rome) King of Spain (1788-1808) during the  turbulent period of the French Revolution. Son of Charles III, he lacked  leadership qualities and entrusted the government to Manuel de Godoy.  After a French invasion in 1794, Spain was reduced to the status of a  French satellite. When Napoleon again occupied northern Spain in 1807,  Charles was forced to abdicate (1808) and go into exile.</p><p>Charles V known as Charles the Wise (b. Jan. 21, 1338, Vincennes,  France�d. Sept. 16, 1380, Nogent-sur-Marne) King of France (1364-80).  He raised money to ransom his father, John II, from the English, under the  terms of the Treaty of Bretigny. Crowned king on his father�s death in  1364, Charles helped the country recover its losses in the first phase of  the Hundred Years' War. When war with England broke out again (1369),  he won a series of victories for the French that nullified the damaging  treaties of 1360. The plots of his enemy Charles II (of Navarra) prompted  him to seize most of the king�s French lands. His support of Pope Clem�  ent VII helped cause the Western Schism.</p><p>Charles V German Karl (b. Feb. 24, 1500, Ghent�d. Sept. 21, 1558,  San Jeronimo de Yuste, Spain) Holy Roman emperor (1519-56) and king  of Spain (as Charles I, 1516-56). Son of Philip I of Castile and grandson  of Ferdinand V and Isabella I and of Emperor Maximilian I, he succeeded to  his grandfathers� kingdoms on their deaths in 1516 and 1519, respectively.  Important events of his reign include the Diet of Worms and the begin�  ning of the Reformation; his defeat of Francis I, which assured Spanish  supremacy in Italy (see Italian Wars); wars against Turkey under Suley�  man I; the formation of the Schmalkaldic League; the Council of Trent; and  the Peace of Augsburg. He struggled to hold his vast Spanish and Hab-  sburg empire together against the growing forces of Protestantism, Turk�  ish and French pressure, and even hostility from Pope Adrian VI. In  1555-56 Charles abdicated his claims to the Netherlands and Spain in  favour of his son Philip II and the title of emperor to his brother Ferdinand  I, and in 1557 he retired to a monastery in Spain.</p><p>Charles VI known as Charles the Well-Beloved or Charles the</p><p>Mad (b. Dec. 3, 1368, Paris, Fr.�d. Oct. 21, 1422, Paris) King of France  (1380-1422). Crowned at age 11, he allowed his uncles and advisers to  rule France until 1388. He suffered fits of madness from 1392, and royal  power waned as the dukes of Burgundy and Orleans grew stronger. The  English invasion and victory at the Battle of Agincourt (1415) obliged  Charles to sign the Treaty of Troyes (1420), which provided for the mar�  riage of his daughter Catherine of Valois to Henry V of England, who was  declared regent of France and heir to the French throne.</p><p>Charles VI German Karl (b. Oct. 1, 1685, Vienna, Austria�d. Oct.  20, 1740, Vienna) Holy Roman emperor (1711�40) and king of Hungary</p><p>(as Charles III). Son of Emperor Leopold I, he tried unsuccessfully to claim  the Spanish throne (as the pretender Charles III), which caused the War  of the Spanish Succession. He conducted a successful war against the Otto�  man Empire (1716-18) but lost the War of the Polish Succession (1733�  38), and a new conflict with Turkey (1736-39) resulted in the loss of most  of the territories gained in 1718. He promulgated the Pragmatic Sanction  in an attempt to ensure that his daughter Maria Theresa would succeed  him, which led to the War of the Austrian Succession.</p><p>Charles VII (b. Feb. 22, 1403, Paris, France�d. July 22, 1461, Mehun-  sur-Yevre) King of France (1422-61). Despite the treaty signed by his  father, Charles Vl, which excluded his succession, Charles assumed the  title of king on his father�s death. In 1429, with the aid of Joan of Arc,  he raised the siege of Orleans. He drove the English from France (1436)  and gradually recovered French lands, ending the Hundred Years' War. His  financial and military reforms increased the power of the monarchy.</p><p>Charles VII German Karl Albrecht (b. Aug. 6, 1697�d. Jan. 20,  1745, Munich) Elector of Bavaria (1726-45) and Holy Roman emperor  (1742-45). He renounced any claims to the Austrian succession when he  recognized the Pragmatic Sanction. However, on the death of Emperor  Charles VI, he joined the alliance against Maria Theresa and was crowned  emperor in 1742. Meanwhile, Bavaria was overrun by Austrian troops.  He was restored by Prussia and France to his Bavarian lands in 1744 but  died soon after.</p><p>Charles VIII (b. June 30, 1470, Amboise, France�d. April 7, 1498,  Amboise) King of France (1483-98). He abandoned claims to parts of  present-day France and Spain, and he consolidated French ownership of  Brittany, in preparation for his grand enterprise, an expedition to Italy to  assert his inherited right to the kingdom of Naples. This inaugurated wars  with Italy that lasted more than 50 years and gained little in return for  vast outlays. Charles was crowned in Naples in 1495, but his opponents  rallied against him and he lost his conquests. He died while preparing  another expedition.</p><p>Charles IX (b. June 27, 1550, Saint-Germain-en-Laye, near Paris,  France�d. May 30, 1574, Vincennes) King of France (1560-74). Son of  Catherine de Medicis, he became king on the death of his brother Francis  II. under his mother�s regency. Though he was proclaimed of age in 1563,  he remained under his mother�s domination. His reign was marked by  conflicts between Catholics and Huguenots, and he was remembered for  authorizing the Saint Bartholomew's Day Massacre (1572) at his mother�s  instigation, an event that apparently haunted him the rest of his life. He  died of tuberculosis at age 23.</p><p>Charles IX Swedish Karl (b. Oct. 4, 1550, Stockholm, Swed.�d. Oct.  30, 1611, Nykoping) King of Sweden (1604-11). Third son of Gustav I  Vasa, he helped lead a rebellion against the rule of his half brother Erik  XIV that placed his other brother on the throne as John III. After the  accession (1592) of his devoutly Catholic nephew, Sigismund III, Charles  called the Convention of Uppsala, which demanded that Lutheranism be  retained as the national religion. He opposed Sigismund in a civil war,  and after the latter was deposed Charles became the virtual ruler of Swe�  den (1599-1604). Declared king in 1604, he pursued an aggressive for�  eign policy that led to war with Poland (1605) and Denmark (the Kalmar  War, 1611-13).</p><p>Charles X (b. Oct. 9, 1757, Versailles, France�d. Nov. 6, 1836, Gori-  zia, Friuli) King of France (1824-30). Fifth son of the dauphin Louis, and  grandson of Louis XV, until 1824 he was known as Charles-Philippe, count  d�Artois. During the French Revolution he went into exile and became the  leader of the emigre nobility. Returning to France in 1814, he led the ultras  during the Bourbon Restoration. On the death of his brother Louis XVIII,  Charles became king. His popularity waned as his reign became increas�  ingly reactionary. After the July Revolution he was forced to abdicate in  favour of Louis- Philippe. His reign dramatized the failure of the Bourbons  to reconcile the tradition of the monarchy by divine right with the demo�  cratic spirit produced in the wake of the Revolution.</p><p>Charles X Gustav Swedish Karl Gustav (b. 1622�d. 1660) King  of Sweden (1654-60). Nephew of Gustav II Adolf, he failed in his efforts  to marry the Swedish queen Christina, but she named him to succeed her.  As king he attempted to restore the public finances but was forced to  devote most of his attention to military matters. He conducted the First  Northern War (1655-60) against a coalition that eventually included  Poland, Russia, Brandenburg, the Netherlands, and Denmark, with the aim</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Charles XI &#x25BA; Charlotte I 377</p><p>of establishing a unified northern state. After conquering Poland (1655�  56), he won back lands in southern Sweden from Denmark by the Treaty  of Roskilde (1658).</p><p>Charles XI Swedish Karl (b. Nov. 24, 1655, Stockholm, Swed.�d.  April 5, 1697, Stockholm) King of Sweden (1660-97). At age five he  succeeded his father, Charles X Gustav, and the kingdom was ruled under  a regency of aristocrats until Charles came of age in 1672. The regents  drew Sweden into the Dutch War (1672-78), but Charles took control of  the armies and won favorable results for Sweden by the Treaties of  Nijmegen, after which he maintained a foreign policy of neutrality. Within  Sweden, Charles expanded royal power at the expense of the higher nobil�  ity and established an absolutist monarchy.</p><p>Charles XII Swedish Karl (b. June 17, 1682, Stockholm, Swed.�d.  Nov. 30, 1718, Fredrikshald, Nor.) King of Sweden (1697-1718). Son of  Charles XI, he became absolute monarch at age 15. He defended his coun�  try for 18 years in the Second Northern War, gradually taking increased  responsibility for planning and executing armed operations. He launched  a disastrous invasion of Russia (1707-09) that resulted in the collapse of  the Swedish armies and the loss of Sweden�s status as a great power. Rul�  ing early in the Enlightenment, he promoted significant domestic reforms.  He was killed during an invasion of Norway.</p><p>Charles XIII Swedish Karl (b. Nov. 8, 1622, Nykoping Castle,  Swed.�d. Feb. 13, 1660, Goteborg) King of Sweden (1809-18) and first  king of the union of Sweden and Norway (1814-18). Second son of King  Adolf Frederick (1710-71), he served as admiral of the fleet in the Russo-  Swedish war. On the death of his brother Gustav III (1792), Charles  became regent for his nephew Gustav IV. After the latter�s deposition in  1809, Charles was elected king. He was prematurely aged and childless.  In 1810 Jean-Baptiste Bemadotte (later Charles XIV John) was named heir  apparent; from then on, Charles was eclipsed by the crown prince.</p><p>Charles XIV John Swedish Karl Johan orig. Jean-Baptiste  Bernadotte (b. Jan. 26, 1763, Pau, France�d. March 8, 1844, Stock�  holm, Swed.) King of Sweden and Norway (1818-44). He became an  ardent supporter of the French Revolution and rose rapidly in the army  ranks to brigadier general (1794). Named marshal of France in 1804, he  supported Napoleon in several campaigns (1805-09) but subsequently  shifted his allegiance. In 1810 he was invited to become crown prince of  Sweden; taking the name of Charles John, he assumed control of the gov�  ernment. He helped defeat Napoleon at the Battle of Leipzig, then defeated  France�s ally Denmark, forcing that country to transfer Norway to the  Swedish crown. On the death of Charles XIII in 1818, Charles John became  king of Sweden and Norway. His foreign policy led to a long and favour�  able period of peace.</p><p>Charles Albert Italian Carlo Alberto (b. Oct. 2, 1798, Turin, Pied�  mont, French Republic�d. July 28, 1849, Oporto, Port.) King of  Sardinia-Piedmont (1831-49). A member of the house of Savoy, he  ascended the throne after the death of Charles Felix in 1831. He mitigated  the harsh administration of his country and accelerated its economic and  social development. The spread of revolutionary ideas forced him to grant  a statute for representative government in 1848. After the election of Pius  IX as pope and the Austrian occupation of Ferrara, he sought to lead the  liberation of Italy. He went to war against Austria in 1848 and again in  1849, but, after his defeat in the Battle of Novara, he abdicated in favor  of his son, Victor Emmanuel II.</p><p>Charles Edward, the Young Pretender orig. Charles  Edward Louis Philip Casimir Stuart known as Bonnie Prince  Charlie (b. Dec. 31, 1720, Rome�d. Jan. 31, 1788, Rome) Claimant to  the British throne. He was the son of the royal pretender James Edward and  grandson of the exiled James II of England. Seeking to regain the throne, in  1745 the �Young Pretender� landed in Scotland, where he raised an army  of 2,400 among the clans. After taking Edinburgh and routing the English  at Prestonpans, he crossed the English border and reached Derby, but a  lack of strong support from the Jacobites and the French forced his retreat  into Scotland. He was decisively defeated at the Battle of Culloden (1746)  and, aided by Flora Macdonald (1722-90) and disguised as her maid,  escaped to France. He wandered about Europe trying to revive his cause,  but his debauched behaviour alienated his friends. He settled in Italy in  1766. He later became romanticized in ballads and legends.</p><p>Charles Martel \mar-'tel\ Latin Carolus Martellus ("Charles  the Hammer") (b. c. 688�d.

He was a child born out of  wedlock to Pippin of Herstal, mayor of the palace and virtual ruler of the  Frankish realm in the waning days of the Merovingian dynasty. On his  father�s death he overcame family opposition and rivals among the nobil�  ity to reunite and rule the entire Frankish realm. He subdued Neustria  (724), attacked Aquitaine, and fought against the Frisians, Saxons, and  Bavarians. His victory at the Battle of Tours/Poitiers (732) stemmed the  Muslim invasion, and he controlled Burgundy by 739. He also supported  the activities of St. Boniface and other missionaries. In Frankish royal tra�  dition, he divided the kingdom between his sons Pippin III and Carloman  who succeeded him as mayor; his grandson was Charlemagne.</p><p>Charles of Anjou See Charles I (Naples)</p><p>Charles of Luxembourg See Charles IV (Holy Roman Empire)</p><p>Charles River River, eastern Massachusetts, U.S. The longest river  wholly in the state, it flows into Boston Bay after a course of about 80  mi (130 km).

An opponent of Louis XI of France, Charles tried to make Bur�  gundy an independent kingdom. He had great success until 1474, casting  off French rule, extending Burgundy�s possessions, and building a cen�  tralized government. Charles brutally quelled a revolt in Liege (1468) and  invaded Normandy (1471). Through negotiation, warfare, and purchases,  he sought to extend his territory as far as the Rhine, but a coalition of  Swiss, Austrians, and towns on the upper Rhine resisted him. He suffered  defeats by the Swiss in 1476 and was killed in battle near Nancy.</p><p>Charles the Fair See Charles IV (France)</p><p>Charles the Fat See Charles III (Holy Roman Empire)</p><p>Charles the Well-Beloved See Charles VI (France)</p><p>Charles the Wise See Charles V (France)</p><p>Charleston Social jazz dance popular in the 1920s and later, charac�  terized by its toes-in, heels-out twisting steps.

He became music director at the principal Jesuit  church in Paris, and for his last six years he held the prestigious post of  maitre de chapelle at the Sainte-Chapelle. Enormously prolific, he was  the most important French composer of his generation. He wrote 11  masses, 84 psalm settings, and 207 motets, including some 35 dramatic  motets or Latin oratorios, a genre he introduced into France. His works  include the oratorio Judicium Salomonis (1702), the mass Assumpta est  Maria , and the operas Medee (1693) and David et Jonathas (1688).</p><p>Charte Constitutionnelle See Charter of 1814</p><p>charter Document granting certain specified rights, powers, privileges,  or functions from the sovereign power of a state to a person, corporation,  city, or other unit of local organization. In Magna Carta (1215), King John  granted certain liberties to the English people. Elsewhere in medieval  Europe, monarchs issued charters to towns, guilds, universities, and other  institutions, granting the institution certain privileges and sometimes  specifying how they should conduct their internal affairs. Later, charters  were granted to overseas trading companies (e.g., the British East India  Co.), granting them monopolies in certain areas. Britain�s colonies in  North America were established by charter. Modern charters may be cor�  porate or municipal. A corporate charter, issued by a governmental body,  grants individuals the power to form a corporation, or limited-liability com�  pany. A municipal charter is a law that creates a new political subdivision  and allows the people within it to organize themselves into a municipal  corporation, in effect delegating to the people the powers of local self-  government.</p><p>Charter Oath or Five Articles Oath Oath issued in 1868 by Japan�s  Meiji emperor. One article, important in spurring the creation of a new leg�  islative body, promised that assemblies would be widely established and  that all matters would be �decided by public discussion.� Two articles  promised an end to feudal class restrictions and �evil customs of the past,�  and another stated that all classes should work together to �carry out the  plan of government.� Lastly, it was declared that �knowledge shall be  sought throughout the world to promote the welfare of the empire.� The  Charter Oath set the progressive tone of the Meiji period. See also Meiji  Restoration.</p><p>Charter of 1814 or Charte Constitutionnelle \ , shart- l ko n -ste-tiE-  syo-'nel\ French constitution issued by Louis XVIII after he became king  (see Bourbon Restoration). The charter, which was revised in 1830 and  remained in effect until 1848, preserved many liberties won by the French  Revolution. It established a constitutional monarchy with a bicameral par�  liament, guaranteed civil liberties, proclaimed religious toleration, and  acknowledged Catholicism as the state religion.</p><p>chartered company Type of corporation that evolved in the 16th  century in Europe. Under a charter granted by the state�s sovereign author�  ity, the company had certain rights and obligations which usually gave it  a trading monopoly in a specific geographic area or for a specific type of  trade item. In the 17th century, chartered companies were encouraged by  the English, French, and Dutch governments to assist trade and encour�  age overseas exploration. Those companies that formed for trade with the  Indies (see English East India Company; Dutch East India Company; French  East India Company) and the New World (see Hudson's Bay Company) had  the most wide-reaching influence. Some chartered companies were also  involved in the settlement of colonists (see London Company; Plymouth  Company). Eventually the development of the modem limited-liability com�  pany or corporation led to a decline in the importance of chartered com�  panies.</p><p>Chartism British working-class movement for parliamentary reform.

In the Middle Ages it was held by the  counts of Blois and Champagne. The city was sold to France in 1286 and  was occupied by the English from 1417 to 1432. Henry IV was crowned  there in 1594.

He practiced law in Cin�  cinnati from 1830, defending runaway slaves and white abolitionists. He  led the Liberty Party in Ohio from 1841 and helped found the Free Soil  Party (1848) and the Republican Party (1854). He served in the U.S. Sen�  ate (1849-55, 1860-61) and was the first Republican governor of Ohio  (1855-59). He served as secretary of the treasury under Pres. Abraham  Lincoln (1861-64). Appointed chief justice of the Supreme Court of the  United States by Lincoln, he presided over the impeachment trial of Pres.

He served on the state Com�  mittee of Correspondence (1774), was elected to the Continental Congress,  and signed the Declaration of Independence. When Alexander Hamilton  exposed his attempt to comer the flour market (1778), Chase retired from  Congress, only to return in 1784. He served as chief judge of the Mary�  land General Court from 1791 to 1796, when Pres. George Washington  appointed him to the Supreme Court of the United States. Chase upheld the  primacy of U.S. treaties over state statutes in Ware v. Hylton. In Calder  v. Bull (1798) he contributed to the definition of due process. At the insti�  gation of Pres. Thomas Jefferson, Chase was impeached for partisan con�  duct in 1804. His acquittal established the principle that federal judges  can be removed only for indictable criminal acts, thus strengthening the  independence of the judiciary. Chase served until 1811.</p><p>Chase, William Merritt (b. Nov. 1, 1849, Williamsburg, Ind.,  U.S.�d. Oct. 25, 1916, New York, N.Y) U.S. painter and teacher.

Chase became the most  important U.S. art teacher of his generation, first at New York�s Art Stu�  dents League and later at his own school, founded in 1896. His teachings,  particularly his advocacy of fresh colour and bravura technique, greatly  influenced the course of early 20th-century U.S. painting; among his stu�  dents were Georgia O'Keeffe and Charles Demuth. As a painter, he was very  prolific; his 2,000 paintings include portraits, interiors (e.g., In the Stu�  dio, 1880-83), figure studies, still lifes, and landscapes characterized by  bold, spontaneous brushwork.</p><p>Chase Manhattan Corp.

His first notable Bengali work was Daughter of  the Lord of the Fort (1865). His epoch-making newspaper, Bangadarsan,  serialized some of his later works. Though his novels were considered  structurally faulty, his contemporaries saw him as a prophet, and his val�  iant Hindu heroes aroused great pride and patriotism. He helped create  the Indian school of fiction and established Bengali prose as a literary  language. Chatterjee is considered the greatest Bengali novelist.</p><p>Chatterton, Thomas (b.

At age 11 Chatterton  wrote a pastoral eclogue on an old parchment and passed it off success�  fully as a 15th-century work. Thereafter he created more poems in a simi�  lar vein, attributing them to a fictitious monk he called Thomas Rowley.  After a mock suicide threat freed him from an apprenticeship to an attor�  ney, he set out for London. There he had some success with a comic opera,  The Revenge , but when a prospective patron died, he found himself pen�  niless and without prospects and committed suicide at 17.

His first important poem. Book of the  Duchesse (1369/70), was a dream vision elegy for the duchess of Lan�  caster. In the 1380s he produced mature works, including The Parliament  of Fowls, a dream vision for St. Valentine�s Day about a conference of  birds choosing their mates; the fine tragic verse romance Troilus and Cri-  seyde; and the unfinished dream vision Legend of Good Women. His best-  known work, the unfinished Canterbury Tales (written 1387-1400), is an  intricate dramatic narrative that employs a pilgrimage to the shrine of St.  Thomas Becket in Canterbury as a framing device for a highly varied col�  lection of stories; not only the most famous literary work in Middle  English, it is one of the finest works of English literature.

As a written order to pay money, a check may be trans�  ferred from one person to another by endorsement. Most checks are not  paid in currency but by the debiting and crediting of bank deposits. There  are several special forms of checks. A cashier�s check is issued by a bank  and has unquestioned acceptability, as does a certified check, which is a  depositor�s check that has been guaranteed by a bank.

Checks and balances,  which modify the separation of powers, may operate under parliamentary  systems through exercise of a parliament�s prerogative to adopt a  no-confidence vote against a government; the government, or cabinet, in  turn, ordinarily may dissolve the parliament. In one-party political sys�  tems, informal checks and balances may operate when organs of an  authoritarian or totalitarian regime compete for power.

When milk sours, it forms  both a protein-rich gel, or curd, and a lactose-rich fluid, or whey. Coagu�  lation is often facilitated by adding rennin, an enzyme that acts on the  milk�s chief protein, casein. The resulting curd is then cut or broken to  release most of the whey. Ripening and curing are affected by moisture  content, acidity, presence of microorganisms, and other factors. Cheese is  made from the milk of cows, goats, sheep, water buffalo, llamas, yaks,  and other animals; in the West, cow�s milk is most common. Products  vary according to fat content of the milk, heating or pasteurization, and  addition of enzymes or cultures of bacteria, molds, or yeasts. Cheese vari�  eties include hard cheeses (e.g., cheddar, Edam, Emmental, Gouda, Pro-  volone, Romano, Swiss), semisoft cheeses (Gorgonzola, Limburger,  Muenster, Roquefort), and soft cheeses (Brie, Camembert, cottage, Neu-  fchatel, and ricotta).

The adult�s  coarse fur is sandy yellow above, white below, and covered with small  black spots; a black streak runs down the face from the corner of each  eye. The cheetah hunts by day, alone or in small groups.</p><p>Cheever, John (b. May 27, 1912, Quincy, Mass., U.S.�d. June 18,  1982, Ossining, N.Y.) U.S. short-story writer and novelist. Cheever lived  principally in southern Connecticut. His stories appeared notably in The  New Yorker , his clear and elegant prose delineating the drama and sad�  ness of life in comfortable suburban America, often through fantasy and  ironic comedy. He has been called the Chekhov of the suburbs. His col�  lections include The Enormous Radio (1953), The Brigadier and the Golf  Widow (1964), and The Stories of John Cheever (1978, Pulitzer Prize).  Among his novels are The Wapshot Chronicle (1957), The Wapshot Scan�  dal (1964), and Falconer (1977). His revealing journals were published  in 1991. Two of his children, Susan and Benjamin, also became writers.</p><p>Cheke Vchek\, Sir John (b. June 16, 1514�d. Sept. 13, 1557, London,  Eng.) English humanist. A supporter of the Reformation, he was named pro�  fessor of Greek at Cambridge University by Henry VIII and knighted by  Edward VI. With his friend, the statesman Thomas Smith (1513-77), he  ably defended the historical pronunciation of Attic Greek, introduced by  Erasmus, in opposition to the post-  Classical pronunciation that was then  the norm. Cheke was imprisoned  briefly on the accession of Mary I; he  fled abroad but was captured in the  Netherlands in 1556 and confined to  the Tower of London. He recanted  Protestantism to avoid execution and  died the following year, allegedly  depressed by his forced abjuration.</p><p>Chekhov Vchek-ofA English  \'chek-of\, Anton (Pavlovich)</p><p>(b.

He took up serious themes  with stories such as �The Steppe� (1888) and �A Dreary Story� (1889);  later stories include �The Black Monk� (1894) and �Peasants� (1897). He  converted his second long play, The Wood Demon (1889), into the mas�  terpiece Uncle Vanya (1897). His play The Seagull (1896) was badly  received until its successful revival in 1899 by Konstantin Stanislavsky  and the Moscow Art Theatre. He moved to the Crimea to nurse his even�  tually fatal tuberculosis, and there he wrote his great last plays. Three Sis�  ters (1901) and The Cherry Orchard (1904), for the Moscow Art Theatre.  Chekhov�s plays, which take a tragicomic view of the staleness of pro�  vincial life and the passing of the Russian gentry, received international  acclaim after their translation into English and other languages, and as a  short-story writer he is still regarded as virtually unmatched.</p><p>Chekiang See Zhejiang</p><p>chelate Vke-,lat\ Any of a class of coordination or complex compounds  consisting of a central atom of a metal (usually a transition element) attached  to a large molecule (ligand). Any ligand that can bind to the metal at two  or more points to form a ring structure, more stable than a nonchelated  compound of the same general chemical formula, is a chelating agent. The  process of binding to the metal is called chelation. Chelating agents such  as EDTA salts are used in medicine to remove toxic metals (e.g., lead,  cadmium) from the body. Others are used in analysis as indicators and in  industry to extract metals.

Chemical energy may be released during a chemical reaction, often in the  form of heat; such reactions are called exothermic. Reactions that require  an input of heat to proceed may store some of that energy as chemical  energy in newly formed bonds. The chemical energy in food is converted  by the body into mechanical energy and heat. The chemical energy in coal  is converted into electrical energy at a power plant. The chemical energy  in a battery can also supply electrical power by means of electrolysis.</p><p>chemical engineering Academic discipline and industrial activity  concerned with developing processes and designing and operating plants to  change materials� physical or chemical states. With roots in the inorganic  and coal-based chemical industries of western Europe and the oil-refining  industry in North America, it was spurred by the need to supply chemicals  and products during the two World Wars. The field includes research,  design, construction, operation, sales, and management activities. Chemi�  cal engineers must master chemistry (including the nature of chemical reac�  tions, the effects of temperature and pressure on equilibrium, and the effects of  catalysts on reaction rates), physics, and mathematics. The engineering  aspect, involving fluid flow (see deformation and flow) and heat and mass  transfer, is broken down into �unit operations,� including vaporization, dis�  tillation, absorption, filtration, extraction, crystallization, agitation and mix�  ing, drying, and size reduction; each is described mathematically, and its  principles apply to any material. Chemical engineers work not only in the  chemical and oil industries but also in such processing industries as foods,  paper, textiles, plastics, nuclear, and biotechnology.</p><p>chemical equation Method of writing the essential features of a chemi�  cal reaction using chemical symbols (or other agreed-upon abbreviations).  By convention, reactants (present at the start) are on the left, products  (present at the end) on the right. A single arrow between them denotes an  irreversible reaction, a double arrow a reversible reaction. The law of  conservation of matter (see conservation law) requires that every atom on  the left appear on the right (the equation must balance); only their arrange�  ments and combinations change. For example, one oxygen molecule com�  bining with two hydrogen molecules to form two water molecules is  written 2H 2 + 0 2 �� 2H 2 0. The dissociation of salt into sodium and chlo�  ride ions is written NaCl �&gt; Na + + Cl - . See also stoichiometry.</p><p>chemical formula Expression of  the composition or structure of a  chemical compound. Formulas for  MOLECULES USe CHEMICAL SYMBOLS with  subscript numbers to show the num�  ber of atoms of each element: 0 2 for  molecular oxygen, 0 3 for ozone,  CH 4 for methane, C 6 H 6 for benzene.  Parentheses may enclose atoms that  act as a group. General formulas  show the proportions of atoms in  members of a class (e.g., C�H 2 � + 2  for alkanes). If the substance does  not exist as molecules (see ionic  bond), empirical formulas show the  relative proportions of the constitu�  ents (e.g., NaCl for sodium chlo�  ride). Structural formulas show  bonds (see bonding) between atoms  in a molecule as short lines between  symbols; they are particularly useful  for showing how isomers differ. A  projection formula also indicates the  three-dimensional arrangement of  the atoms (see Fischer projection; ste�  reochemistry).</p><p>chemical hydrology or  hydrochemistry Subdivision of  hydrology that deals with the chemi�  cal characteristics of the water on  and beneath the surface of the Earth.

Chemical hydrology is concerned with the processes involved and  thus includes study of phenomena such as the transport of salts from land  to sea (by erosion of rocks and surface runoff) and from sea to land (by  evaporation, cloud formation, and precipitation) and the age and origin of  groundwater in desert regions and of ice sheets and glaciers.</p><p>chemical reaction Any chemical process in which substances are  changed into different ones, with different properties, as distinct from  changing position or form (phase). Chemical reactions involve the rupture  or rearrangement of the bonds holding atoms together (see bonding), never  atomic nuclei. The total mass and number of atoms of all reactants equals  those of all products, and energy is almost always consumed or liberated  (see heat of reaction). The speed of reactions varies (see reaction rate).  Understanding their mechanisms lets chemists alter reaction conditions to  optimize the rate or the amount of a given product; the reversibility of the  reaction and the presence of competing reactions and intermediate prod�  ucts complicate these studies. Reactions can be syntheses, decomposi�  tions, or rearrangements, or they can be additions, eliminations, or  substitutions. Examples include oxidation-reduction, polymerization, ion�  ization (see ion), combustion (burning), hydrolysis, and acid-base reactions.</p><p>chemical symbol Notation of one or two letters derived from the sci�  entific names of the chemical elements (e.g., S for sulfur, Cl for chlorine,  Zn for zinc). Some hark back to Latin names: Au (durum) for gold, Pb  ( plumbum ) for lead. Others are named for people or places (e.g. einstein�  ium, Es, for Einstein). The present symbols express the system set out by  the atomic theory of matter. John Dalton first used symbols to designate  single atoms of elements, not indefinite amounts, and Jons Jacob Berzelius  gave many of the current names. Chemical formulas of compounds are  written as combinations of the elements� symbols, with numbers indicat�  ing their atomic proportions, using various conventions for ordering and  grouping. Thus, sodium chloride is written as NaCl and sulfuric acid as  H 2 S0 4 .</p><p>chemical warfare Use of lethal or incapacitating chemical weapons  in war, and the methods of combating such agents. Chemical weapons  include choking agents such as the chlorine and phosgene gas employed  first by the Germans and later by the Allies in World War I; blood agents  such as hydrogen cyanide or cyanogen gas, which block red blood cells  from taking up oxygen; blister agents such as sulfur gas and Lewisite,  also dispensed as a gas, which burn and blister the skin; and nerve agents  such as Tabun, Sarin, Soman, and VX, which block the transmission of  nerve impulses to the muscles, heart, and diaphragm. The horrific casu�  alties suffered in World War I led to the 1925 Geneva Protocol, which  made it illegal to employ chemical weapons but did not ban their pro�  duction. Chemical weapons were used a number of times afterward, most  notably by Italy in Ethiopia (1935-36), by Japan in China (1938^-2), by  Egypt in Yemen (1966-67), and by Iran and Iraq against each other (1984-  88). During the Cold War the Soviet Union and U.S. built up enormous  chemical arsenals; these were dismantled under the terms of the 1993  Chemical Weapons Convention, which prohibits all development, pro�  duction, acquisition, stockpiling, or transfer of such weapons. Not all  countries have signed the convention, and many are suspected of pursu�  ing clandestine chemical programs. Many military forces have adopted  various defensive measures, including chemical sensors, protective gar�  ments and gas masks, decontaminants, and injectable antidotes, and some  have reserved the option of retaliating in kind to any chemical attack. In  1995 a religious cult killed 12 civilians and injured thousands more with  Sarin gas in Tokyo; this pointed out the power of chemical agents as  weapons of terror as well as the difficulty of protecting civilian popula�  tions.

Chemoreceptors that are components of sensory neu�  rons that directly convert chemical stimuli are called primary receptors.  Secondary receptors are not part of neurons but respond to stimulation by  inducing activity in an adjacent neuron. Most mammals possess two  classes of chemoreceptors: the primary receptors involved in smell and  located in the epithelium of the nasal cavity and the secondary receptors  involved in taste and located in the tongue�s taste buds. Aquatic animals  and terrestrial species with mucus-secreting skins typically possess  chemoreceptors all over the body. For many animals, chemoreception is  the most important means of receiving information about their surround�  ing environment. Chemoreception plays roles in finding appropriate food  and in reproductive behaviour (see pheromones). It serves additional pur�  poses in some animals, such as distinguishing members of the same com�  munity from outsiders.</p><p>chemotaxonomy V.ke-mo-tak-'sa-no-meV Method of biological clas�  sification based on similarities in the structure of certain compounds  among the organisms being classified.

As a young man, Chen studied in Japan. In  China, he started subversive periodicals that were quickly suppressed by  the government. In 1915, after the establishment of the Chinese republic,  he created the monthly Qingnian zazhi (�Youth Magazine�), renamed Xin  qingnian (�New Youth�), in which he proposed that the youth of China  rejuvenate the nation intellectually and culturally; Lu Xun, Hu Shih, and  Mao Zedong were all contributors. In 1917 Chen was appointed dean of  the School of Letters at Beijing University. In 1919 he was imprisoned  briefly for his role in the May Fourth Movement; on his release he became  a Marxist. With Li Dazhao he founded the Chinese Communist Party in  1920; he is regarded as �China�s Lenin.� The Communist International  had him removed as party leader when the party�s alliance with the  Nationalist Party fell apart, and he was expelled from the party in 1929.

Cherokee culture resembled that of the Creek and other  Southeastern Indians. Their name is derived from a Creek word meaning  �people of different speech�; many prefer to be known as Keetoowah or  Tsalagi. Cherokee is an Iroquoian language, but it differs considerably  from other Iroquoian languages. At the time of first contact, the Cherokee  possessed stone implements, wove baskets, made pottery, cultivated com,  beans, and squash, and hunted deer, bear, and elk. Wars and treaties in the  late 18th century severely reduced Cherokee power and landholdings.  After a series of failed raids against U.S. troops and civilian settlements,  they ceded land to attain peace and to pay debts. After 1800 the Cherokee  were remarkable for their assimilation of European/American culture,  forming a government modeled on that of the U.S. and adopting European  methods of farming and homemaking. Most became literate following the  development of a syllabary by Sequoyah. Beginning c. 1835, when gold  was discovered on Cherokee land in Georgia, agitation increased for their  removal to the West. The ensuing events culminated in the Trail of Tears,  which left some 4,000 Cherokee dead. People claiming sole Cherokee  descent numbered some 281,000 in the 2000 U.S. census.</p><p>cherry Any of various trees of the genus Primus and their edible fruits.  Most are native to the Northern  Hemisphere, where they are widely  grown. Three types are grown  mainly for their fruit: sweet cherries  (P. avium ); sour, or tart, cherries (P.  cerasus)\ and, to a much lesser  extent, dukes (crosses of sweet and  sour cherries). Sweet-cherry trees are  large, and their fruit is generally  heart-shaped to nearly globular, var�  ies in colour from yellow through red  to nearly black, and has a low acid  content. Sour-cherry trees are  smaller and bear fruit that is round  to oblate, generally dark red, and  more acidic. Dukes are intermediate  in both tree and fruit characteristics.</p><p>The wood of some cherry species is  especially esteemed for the manufac�  ture of fine furniture. Ornamental  varieties selected for the beauty of  their flowers are a common feature  of gardens.</p><p>Cherry Valley Raid (Nov. 11, 1778) Attack during the American Revo�  lution by Iroquois Indians on a New York frontier settlement.

The city, founded by Ionian Greeks in the 6th century bc, later</p><p>traded with Athens, Delos, and Rhodes and flourished under the Romans  and Byzantines. Thracian Chersonese constituted the modern Gallipoli  Peninsula. On the main trade route between Europe and Asia, it was the  site of several cities founded by Aeolians and Ionians in the 7th century  bc. Abandoned to Darius I in 493 bc, it came under Athenian control and  was later dominated by Augustus.</p><p>chert and flint Very fine-grained quartz, a silica mineral with minor  impurities. Flint is gray to black and nearly opaque (translucent brown in  thin splinters). Opaque, dull, whitish to pale brown or gray specimens are  called simply chert. Chert and flint provided the main source of tools and  weapons for Stone Age people. Flint is used today as an abrasive agent  on sandpapers and in mills that grind raw materials for the ceramic and  paint industries. Considerable amounts of chert are also used in road con�  struction and as concrete aggregate. Some chert takes an excellent polish  and is used as semiprecious jewelry.

Bom into a musical family, the precocious youth  had written dozens of works before he was 20 years old. In 1786 he settled  permanently in Paris. He enjoyed operatic successes in the 1790s, and  Napoleon expressed his particular admiration. He became  co-superintendent of the royal chapel in 1816 and in 1822 director of the  Paris Conservatoire, where he would remain the rest of his life. Ludwig  van Beethoven called Cherubini his greatest contemporary. His counter�  point text (1835) was used widely for a century. Of his nearly 40 operas,  the most popular were Lodoi'ska (1791), Medee (1797), and Les Deux  Journees (1800). His other important works include a symphony (1815),  six string quartets, requiems in C minor and D minor (1816, 1836), and  nine surviving masses.</p><p>Chesapeake Vche-s9-,pek\ City (pop., 2000: 199,184), southeastern  Virginia, U.S. Located south of Norfolk, it was formed as an independent  city in 1963 by the merger of Norfolk county and the city of South Nor�  folk.

In 1840 she married James Chesnut, Jr., who  would play an important role in the secession movement and the Con�  federacy. After her husband became an officer in the Confederate army,  she accompanied him on his military missions and recorded her views  and observations in her journal.

As a young school principal in North Carolina, he  was so distressed by the treatment of African Americans that he moved  his family to Cleveland, where he became an attorney and began writing  in his spare time. He published numerous tales and essays, two collec�  tions of short stories, a biography of Frederick Douglass, and three nov�  els, including The Colonel�s Dream (1905). A psychological realist, he  used familiar scenes of folk life to protest social injustice.</p><p>chess Checkerboard game for two players, each of whom moves 16  pieces according to fixed rules across the board and tries to capture or  immobilize (checkmate) the opponent�s king. The game may have origi�  nated in Asia about the 6th century, though it continued to evolve as it  spread into Europe in Byzantine times; its now-standard rules first became  generally accepted in Europe in the 16th century. The players, designated  white or black, start with their pieces arranged on opposite ends of the  board. Kings move one square in any direction�but not into attack  (check). Bishops move diagonally, and rooks horizontally or vertically, any  number of unobstructed squares. Queens move like either bishops or rooks.  Knights move to the nearest nonadjacent square of the opposite colour (an  �L� shape) and ignore intervening chessmen. Pieces capture by moving to  an enemy-occupied square. Pawns move forward one square (except one or  two on their first move) and are promoted to any non-king piece if they  eventually reach the last row. Pawns capture only one diagonal square for�  ward of them. For one turn only, a pawn has the option, known as en pas�  sant, of capturing an enemy pawn that has just made a first move of two  squares to avoid being captured by moving only one; the capture occurs as  though the pawn had moved only one square. When the first row between  a king and either rook is clear, and as long as the king and that rook have not  moved, a maneuver known as castling can be done in which the king is  shifted two squares toward that rook and the rook is placed directly on the  other side of the king. Kings cannot castle when in check or through any  square in which they would be in check. A draw, known as a stalemate,  occurs if a player is not in check but any move he could make would place  him in check. A draw also occurs if the same position occurs three times  (such as through �perpetual check�). See illustration opposite.</p><p>Chess, Leonard orig. Lejzor Czyz (b. March 12, 1917, Motule,  Pol.�d.

Native to temperate regions  of the Northern Hemisphere, they bear burrlike fruits that contain two or  three edible nuts. The usually tall trees have furrowed bark and lance�  shaped leaves. The American chestnut (C. dentata), which once extended  over a large area of eastern North America, has been almost eliminated  by chestnut blight. The other three species are the European chestnut (C.  sativa), the Chinese chestnut (C. mollissima), and the Japanese chestnut  (C. crenata ). The nuts of these three have local importance as food and  are exported in large quantities, and varieties of all three are cultivated  as ornamentals. The European chestnut produces useful timber as well;  the American chestnut also was an important source of lumber and nuts  before the arrival of the blight.</p><p>chestnut blight Plant disease caused by the fungus Endothia parasit�  ica. Accidentally imported from East Asia and first observed in 1904 in  New York, it has killed almost all native American chestnuts ( Castanea  dentata ) in the U.S. and Canada and is destructive in other countries.  Other blight-susceptible species include the European chestnut (C. sativa),  the post oak ( Quercus stellata ), and the live oak. Symptoms include red�  dish brown bark patches that develop into sunken or swollen and cracked  cankers that kill twigs and limbs. Leaves on such branches turn brown  and wither but remain attached for months. Gradually the entire tree dies.  The fungus persists for years in short-lived sprouts from old chestnut roots  and in less susceptible hosts. It is spread locally by splashing rain, wind,  and insects, and over long distances by birds. Chinese (C. mollissima )  and Japanese (C. crenata) chestnuts are resistant.</p><p>Chetumal \,cha-tu-'mal\ City (pop., 2000: 121,602), capital of Quin�  tana Roo state, Mexico.

After receiving military  training in Tokyo, in 1918 he joined  Sun Yat-sen, leader of the National�  ist Party, which was trying to con�  solidate control over a nation in  chaos. In the 1920s Chiang became  commander in chief of the revolu�  tionary army, which he sent to crush  warlords active in the north (see  Northern Expedition). In the 1930s he  and Wang Jingwei vied for control of  a new central government with its  capital at Nanjing. Faced with Japa�  nese aggression in Manchuria and  communist opposition led by Mao  Zedong in the hinterland, Chiang  decided to crush the communists first. This proved to be a mistake, and  Chiang was forced into a temporary alliance with the communists when  war broke out with Japan in 1937. After the war China�s civil war  resumed, culminating in the Nationalists� flight to Taiwan in 1949, where  Chiang ruled, supported by U.S. economic and military aid, until his  death, when his son, Chiang Ching-kuo, took up the reins of government.  His years ruling Taiwan, though dictatorial, oversaw the island�s eco�  nomic development and increasing prosperity even in the face of its pre�  carious geopolitical position. His failure to keep control of mainland  China has been attributed to poor morale among his troops, lack of respon�  siveness to popular sentiment, and lack of a coherent plan for making the  deep social and economic changes China required.</p><p>Chiang Mai Vjyaq-'mA City (pop., 1999 est.: 171,594), northwestern  Thailand.

Leonardo da Vinci brought the  technique to its full potential, but it is usually associated with such 17th-  century artists as Caravaggio and Rembrandt, who used it to outstanding  effect. The chiaroscuro woodcut, produced by printing different tones of  a colour from separate woodblocks on a single sheet of paper, was first  produced in 16th-century Italy.</p><p>Chibcha \'chib-,cha\ or Muisca \'mwesko\ Group of South American  Indians who at the time of the Spanish conquest occupied the high val�  leys surrounding what are now Bogota and Tunja in Colombia. They had  a population of more than 500,000 and were more centralized politically  than any other South American people outside the Inca empire. Their  economy was based on intensive agriculture, a variety of crafts, and exten�  sive trade. Society was highly stratified. The Chibchan political structure  was crushed by Spanish invaders in the 16th century, and by the 18th cen�  tury they had been assimilated into the rest of the population.

In the 17th century the name was associated with a por�  tage between the Des Plaines and Chicago rivers connecting the St.  Lawrence River and the Great Lakes with the Mississippi River. Fort Dearborn  was built in 1803 on a tract acquired from Indians. It expanded rapidly  after the completion of the Illinois and Michigan Canal (1848), which  connected the Chicago and Mississippi rivers, and also became the  nation�s chief rail centre. Rebuilt quickly after a hugely destructive fire  in 1871, it was the site of the World�s Columbian Exposition in 1893. It  was the birthplace of the steel-frame skyscraper in the late 19th century,  and it boasts designs by eminent architects, including Louis H. Sullivan,  Frank Lloyd Wright, and Ludwig Mies van der Rohe. Nuclear scientists pro�  duced the first nuclear chain reaction at the University of Chicago in 1942.  After World War II the city underwent another building boom, but, as in  other large cities, its population subsequently dropped as its suburbs grew.  The third largest U.S. city, it is a major industrial, commercial, and trans�  portation centre and is the site of the Chicago Mercantile Exchange and  the Chicago Board of Trade. Several museums and the Art Institute of Chi�  cago are located there.</p><p>Chicago, Judy orig. Judy Cohen (b. July 20, 1939, Chicago, Ill.,  U.S.) U.S. multimedia artist. She studied at UCLA, and in 1970 she  adopted the name of her hometown. Motivated by perceived discrimina�  tion in the art world and alienation from canonical art traditions, she  developed �environments� featuring feminine imagery. Her most notable  work, The Dinner Party (1974-79), is a triangular table with place set�  tings for 39 important women, each represented by personalized ceramic  plates and table runners embellished with embroidery styles typical of  their eras. This installation established her reputation as a leader in femi�  nist art. In 1973 she cofounded the Feminist Studio Workshop and Wom�  an�s Building in Los Angeles.</p><p>Chicago, University of Independent university in Chicago, Illinois,  U.S. It was founded in 1890 with an endowment from John D. Rockefeller.  William Rainey Harper, its first president (1891-1906), did much to estab�  lish its reputation, and under Robert M. Hutchins (1929-51) the university  came to be recognized for its broad liberal arts curriculum. The world�s first  department of sociology was established there in 1892 under Robert E. Park.  In 1942 it was the site of the first controlled self-sustaining nuclear chain  reaction, under the direction of Enrico Fermi. Other notable achievements  include the development of carbon- 14 dating and the isolation of plutonium.  More than 70 scholars associated with the University of Chicago have been  awarded Nobel Prizes in their fields. The university comprises an under�  graduate college, several professional schools, and centres for advanced  research, including the Oriental Institute (Middle Eastern studies), Yerkes  Observatory, the Enrico Fermi Institute, and the Center for Policy Study.

Its leading writers� Theodore Dreiser, Sherwood  Anderson, Edgar Lee Masters, and Carl Sandburg �realistically depicted  the contemporary urban environment, condemning the loss of traditional  rural values in the increasingly industrialized and materialistic American  society. Associated with the period were the Little Theatre, an outlet for  young playwrights; the Little Room, a literary group; and magazines such  as The Dial , Poetry, and The Little Review. The renaissance also encom�  passed a revitalization of newspaper journalism as a literary medium.</p><p>Chicago Race Riot of 1919 Most severe of about 25 race riots  throughout the U.S. in the summer after World War I. Racial friction was  intensified by the migration of African Americans to the North. On Chi�  cago�s South Side, the African American population had increased in 10  years from 44,000 to 109,000. The riot was triggered by the death of an  African American youth swimming in Lake Michigan near a beach  reserved for whites; he was stoned and he shortly drowned. When police  refused to arrest the white man allegedly responsible, fighting broke out  between gangs of African Americans and whites. Violence spread  throughout the city, unchecked by the state militia. After 13 days, 38  people were dead (23 African Americans, 15 whites), and 537 injured,  and 1,000 African American families were made homeless.</p><p>Chicago River River, northeastern Illinois, U.S. A small river, consist�  ing of a northern and a southern branch, it originally flowed through Chi�  cago into Lake Michigan. After a severe storm in 1885 caused the river  to empty large amounts of polluted water into the lake, the river�s flow  was reversed by constructing a canal, completed in 1900, the building of  which was considered a significant engineering feat. Now flowing inland,  it is connected with the Des Plaines River by the Chicago Sanitary and Ship  Canal.</p><p>Chicago School Group of architects and engineers who in the 1890s  exploited the twin developments of structural steel framing and the elec�  trified elevator, paving the way for the ubiquitous modern-day skyscraper.  Their work earned Chicago a reputation as the �birthplace of modern  architecture.� Among the school�s members were Louis Sullivan, Daniel  Burnham, and John Wellborn Root (1850-91).</p><p>Chicago Tribune Daily newspaper published in Chicago. The Tribune  is one of the leading U.S. newspapers and long has been the dominant  voice of the Midwest. Founded in 1847, it was bought in 1855 by six  partners, including Joseph Medill (1823-99), who made the paper suc�  cessful and increased its stature while promulgating his generally liberal  views. He bought a controlling interest in 1874 and was publisher until  his death. During Robert McCormick�s tenure (1914-55), the paper  achieved the largest circulation among U.S. standard-sized newspapers  and led the world in newspaper advertising revenue. The Tribune also  reflected his nationalist-isolationist views, but its editorial positions mod�  erated after his death. It subsequently became the flagship of the Tribune  Company, which has holdings in broadcasting, cable TV, publishing, and  other media.</p><p>Chichen Itza \che-'chen-et-'sa\ Ancient ruined Mayan city in Mexico�s  Yucatan state. Chichen Itza was founded by the Maya about the 6th cen�  tury ad in an arid region where water was obtained from natural wells  called cenotes. The city was invaded in the 10th century�probably by a  Mayan-speaking group under strong Toltec influence�and the invaders  constructed another series of buildings, including the famous stepped  pyramid known as El Castillo and a ball court. The site, though largely  abandoned by the time the Spanish arrived in the 16th century, remained  sacred to the Maya people. It was designated a World Heritage site in  1988.

An aristocrat by birth, he entered the imperial diplo�  matic service in 1897 but resigned to join the revolutionary movement  and the Menshevik faction (1905). In 1918 he joined the Bolsheviks and  resumed his diplomatic career, helping negotiate the Treaty of Brest-  Litovsk. As people�s commissar for foreign affairs (1918-28), he led the  Soviet delegation to the Conference of Genoa and later secretly negoti�  ated the Treaty of Rapallo with Germany.</p><p>Chichester City (pop., 2001: 27,477), Chichester district, administra�  tive county of West Sussex, England. It is located northeast of Portsmouth.  The basic plan of the Roman town is preserved in the modem one. The  economy relies mainly on agriculture and retailing. Chichester is noted  for its early Norman cathedral, begun in the late 11th century, and for its  pastoral landscapes.</p><p>chickadee Any of several North American songbird species in the  genus Parus (family Paridae), whose  name imitates their call notes. They  are friendly and easily attracted to  feeders. The black-capped chickadee  (P. atricapillus), found across North  America, is 5 in. (13 cm) long and  has a dark cap and bib. Old World  members of the genus and some New  World members are called TITS or tit�  mice.</p><p>Chickamauga, Battle of (Sept.</p><p>19-20, 1863) Engagement in the  American Civil War fought over con�  trol of the railroad centre of nearby  Chattanooga, Tenn. Confederate  forces under Braxton Bragg and  James Longstreet attacked Union  forces under William Rosecrans. After two days of fierce fighting, most of  the Union army withdrew in disorder, though troops under George H.  Thomas withstood the assault until the assistance of a reserve corps made  possible an orderly withdrawal to Chattanooga. Casualties numbering  16,000 Union and 18,000 Confederate troops made this one of the bloodi�  est battles of the war. Bragg and the Confederate force did not follow up  their victory, and the subsequent Battle of Chattanooga reversed the  results.</p><p>Chickasaw North American Indian people living mainly in Oklahoma,  U.S. Their language, Chickasaw, is a Muskogean language closely related  to that of the Choctaw. The Chickasaw, who once inhabited Kentucky,  Tennessee, northern Mississippi, and Alabama, were a seminomadic  people whose dwellings were loosely scattered along rivers rather than  clustered in villages. They traced descent through the maternal line. The  supreme deity was associated with the sky, sun, and fire. They frequently  raided and intermarried with other tribes, and they were known to white  traders as �mixed-bloods� or �breeds.� In the 1830s they were forcibly  removed to Indian Territory (Oklahoma). In the 2000 U.S. census some  20,000 individuals claimed sole Chickasaw descent.</p><p>The Castillo (background) and a portion of the Colonnade, Chichen Itza</p><p>JOSEF MUENCH</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>390 I chicken &#x25BA; child abuse</p><p>chicken One of the most widely domesticated poultry species ( Gallus  gallus ), raised worldwide for its meat and eggs. Descended from the wild  red jungle fowl of India, chickens have been domesticated for at least 4,000  years. Not until the 19th century did chicken meat and eggs become mass-  production commodities. Modem high-volume poultry farms, with rows of  cages stacked indoors for control of heat, light, and humidity, began to pro�  liferate in Britain c. 1920 and in the U.S. after World War II (see factory  farming). Females are raised for meat and eggs; immature males are cas�  trated to become meat birds called capons.

It usually occurs in epidemics among young chil�  dren, causes a low fever, and runs a mild course, leaving patients immune.  The blisters can scar if scratched. The virus that causes chickenpox  (varicella-zoster virus) can reactivate years later, causing shingles. Zoster  immune globulin (ZIG) can prevent chickenpox in children with leuke�  mia or immunodeficiency disorders who are exposed to the virus. A vac�  cine has also been developed.</p><p>chickpea or garbanzo Annual legume ( Cicer arietinum) widely  grown for its nutritious seeds. The bushy 2-ft (60-cm) plants bear pinnate  leaves and small white or reddish flowers. The yellow-brown peas are  borne one or two to a pod. Chickpeas are an important food plant in India,  Africa, and Central and South America. They are the main ingredient of  hummus, a sauce originating in the Middle East. In southern Europe,  chickpeas are a common ingredient in soups, salads, and stews. A kind  of meal or flour is also made from chickpeas.</p><p>chickweed Either of two species of small-leaved weeds, in the pink  family. Common chickweed, or stitchwort (&#x25A0; Stellaria media), is native to  Europe but widely naturalized. It usually grows to 18 in. (45 cm) but is  a low-growing and spreading annual weed in mowed lawns. Mouse-ear  chickweed ( Cerastium vulgatum ), also from Europe, is a usually shorter,  mat-forming, spreading perennial with many upright stems. It grows in  lawns, pastures, and cultivated fields throughout temperate regions. Both  species have inconspicuous but delicate white, star-shaped flowers.</p><p>chicory Blue-flowered perennial plant ( Cichorium intybus) of the COM�  POSITE family. Native to Europe, it was introduced to the U.S. late in the  19th century. Chicory has a long, fleshy taproot; a rigid, branching, hairy  stem; and lobed, toothed leaves, similar in appearance to dandelion leaves,  around the base. Both roots and leaves are edible. The roots are used as  a flavouring in or substitute for coffee. The plant is also grown as a fod�  der or herbage crop for cattle.</p><p>chief justice Presiding judicial officer within any multijudge court. It  is the title of the highest judicial officer in any U.S. state, and of the leader  of the U.S. Supreme Court. The U.S. chief justice, like the associate jus�  tices, is nominated by the president and confirmed by the Senate for a  lifetime tenure. The chief justices of some state supreme courts are sub�  ject to popular election and mandatory retirement ages. Chief justices are  normally responsible for the administration of their own court and the  preparation of the judiciary�s budget.</p><p>chiefdom Type of sociopolitical organization in which political and  economic power is exercised by a single person (or group) over many  communities. It represents the centralization of power and authority at the  expense of local and autonomous groupings. Political authority in chief-  doms, such as those found in western Africa or Polynesia, is inseparable  from economic power, including the right by rulers to exact tribute and  taxation. A principal economic activity of the heads of chiefdoms is to  stimulate the production of economic surpluses, which they then redis�  tribute among their subjects on various occasions.

It consists largely of an elevated plain sloping northward  toward the Rio Grande. Its western area is broken by the Sierra Madre  Occidental. Chihuahua�s Copper Canyon (Barranca del Cobre) resembles  the U.S. Grand Canyon in scale but is almost inaccessible.

Born into a samurai family, he was attached  to the court aristocracy at Kyoto before moving to Osaka to be near its  puppet theatre. He is credited with more than 100 plays, mainly histori�  cal romances and domestic tragedies, many based on actual incidents.  Most were written for the bunraku, which he raised to artistic heights. His  most popular work was The Battles of Coxinga (1715), a historical melo�  drama based on the life of Zheng Chenggong. Also famous is Double Sui�  cide at Amijima (1720). He is widely regarded as the greatest of Japanese  dramatists.</p><p>Child, Julia orig. Julia McWilliams (b. Aug. 15, 1912 , Pasadena,  Calif., U.S.�d.

She was raised in an abolitionist family and was greatly influenced  by her brother, a Unitarian clergyman. She wrote historical novels and  published a popular manual, The Frugal Housewife (1829). After meet�  ing William Lloyd Garrison in 1831, she became active in abolitionist work.  Her Appeal in Favor of That Class of Americans Called Africans (1833)  was widely read and induced many to join the abolitionist cause. From  1841 to 1843 she edited the National Anti-Slavery Standard. Her home  was a stage on the Underground Railroad.</p><p>child abuse Crime of inflicting physical or emotional injury on a child.  The term can denote the use of inordinate physical violence or verbal  abuse; the failure to furnish proper shelter, nourishment, medical treat�  ment, or emotional support; incest, rape, or other instances of sexual moles�  tation; and the making of child pornography. Child abuse can cause serious  harm to its victims.

In many cases, the abuser himself  suffered abuse as a child. When abuse results in death, evidence of child  abuse or battered-child syndrome (e.g., broken bones and lesions, either  healed or active) is often used to establish that death was not accidental.</p><p>child development Growth of perceptual, emotional, intellectual, and  behavioral capabilities and functioning during childhood (prior to  puberty). It includes development of language, symbolic thought, logic,  memory, emotional awareness, empathy, a moral sense, and a sense of  identity, including sex-role identity.</p><p>child labour Employment of boys and girls in occupations deemed  unfit for children. Such labour is strictly controlled in many countries as  a result of the effective enforcement of laws passed in the 20th century  (e.g., the United Nations Declaration of the Rights of the Child in 1959).  In developing nations the use of child labour is still common. Restrictive  legislation has proved ineffective in impoverished societies with few  schools, although some improvements have resulted from global activ�  ism, such as boycotts of multinational firms alleged to be exploiting child  labour abroad.</p><p>child psychiatry Branch of medicine concerned with mental, emo�  tional, and behavioral disorders of childhood. It arose as a separate field  in the 1920s, largely because of the pioneering work of Anna Freud.  Therapy usually involves the family, whose behaviour powerfully affects  children�s emotional health. Parental death or divorce may affect a child�s  emotional growth. Child abuse and neglect have also been recognized as  significant in childhood disorders. Learning disabilities need to be distin�  guished from emotional problems�which they can also cause if not diag�  nosed in time.</p><p>child psychology Study of the psychological processes of children.  The field is sometimes subsumed under developmental psychology. Data are  gathered through observation, interviews, tests, and experimental meth�  ods. Principal topics include language acquisition and development,  motor skills, personality development, and social, emotional, and intellec�  tual growth. The field began to emerge in the late 19th century through the  work of German psychophysiologist William Preyer, American psycholo�  gist G. Stanley Hall, and others. In the 20th century the psychoanalysts  Anna Freud and Melanie Klein devoted themselves to child psychology, but  its most influential figure was Jean Piaget, who described the various  stages of childhood learning and characterized children�s perceptions of  themselves and the world at each stage.

His uncle, Guntram of Burgundy, adopted Childebert as  his heir in 577. When he came of age he purged the Austrasian nobility  (584) and launched a series of unsuccessful campaigns against the Lom�  bards of Italy. He became ruler of Burgundy on his uncle�s death in 592.</p><p>Children's Crusade (1212) Religious movement in Europe in which  thousands, including many children and young people, set out to take the  Holy Land from the Muslims by love instead of by force. The events of  the Crusade are disputed. According to one version, only partially accu�  rate, the first group of approximately 30,000 was led by a French shep�  herd boy, Stephen of Cloyes, who had a vision of Jesus and received a  letter from him. Stephen led the Crusade to Paris and delivered the letter  to King Philip II Augustus, who dispersed the Crusaders. A German boy  led the second group across the Alps; a few survived to reach Rome, where  Innocent III released them from their vows. Contemporary accounts  describing horrible fates of the participants should be treated cautiously  because they were written by those hostile to the movement. Though the</p><p>movement ended without reaching the Holy Land, it excited religious fer�  vour that helped initiate the Fifth Crusade (1217-21).</p><p>children's literature Body of written works produced to entertain or  instruct young people. The genre encompasses a wide range of works,  including acknowledged classics of world literature, picture books and  easy-to-read stories, and fairy tales, lullabies, fables, folk songs, and other,  primarily orally transmitted, materials. It emerged as a distinct and inde�  pendent form only in the second half of the 18th century and blossomed  in the 19th century. In the 20th century, with the attainment of near-  universal literacy in most developed nations, the diversity in children�s  books came almost to rival that of adult popular literature.</p><p>Childress Vchil-drosV Alice (b.

Language: Spanish (official). Religion: Christianity  (predominantly Roman Catholic; also Protestant, other Christians). Cur�  rency: Chilean peso. Chile is noteworthy for its unique topography: it is  a long, narrow country lying between the Andes Mountains and the Pacific  Ocean. From north to south it is about 2,700 mi (4,300 km) long and  nowhere more than 217 mi (349 km) wide. The north has an arid plateau,  the Atacama Desert, and contains several peaks above 16,000 ft (4,900  m), but most of the highest peaks are on the borders with Bolivia and  Argentina. The rivers, including the Bio-Bio, are limited in size. There are  many lakes, including Lake Llanquihue. The extreme southern coast is  marked by many inlets, islands, and archipelagoes; the western half of  Tierra del Fuego (including the island on which Cape Horn is located) is  in Chilean territory, as are small islets of Juan Fernandez and Easter Island.  Chile has a partially developed free-market economy based mainly on  mining and manufacturing. It is a republic with two legislative houses; its  head of state and government is the president. Originally inhabited by  native peoples, including the Mapuche, the area was invaded by the Span�  ish in 1536. A settlement begun at Santiago in 1541 was governed under  the Viceroyalty of Peru but became a separate captaincy general in 1778.  Its people revolted against Spanish rule in 1810; independence was finally  assured by the victory of Argentine and Chilean forces under Jose de San  Martin at the Battle of Chacabuco in 1817. The area was governed by  Chilean Gen. Bernardo O'Higgins until 1823. In the War of the Pacific  (1879-83) against Peru and Bolivia, Chile won the rich nitrate fields on  the coast of Bolivia, effectively severing that country�s access to the coast.  Chile remained neutral in World War I (1914-18) and for most of World  War II (1939^-5), though in 1942 it joined other Latin American coun�  tries in declaring war on the Axis. In 1970 Salvador Allende was elected  president, becoming the first avowed Marxist to be elected head of state  in Latin America. Following economic upheaval, he was overthrown in  1973 in a coup led by Augusto Pinochet, whose military regime harshly  suppressed internal opposition. A national referendum in 1988 and elec�  tions the following year removed Pinochet from power and returned the  country to democratic rule. Chile�s economy maintained steady growth  through most of the 1990s and in the early 21st century remained one of  the strongest in Latin America.</p><p>Chilka Lake Lake, eastern India. Located in Orissa state, and separated  from the Bay of Bengal by a narrow spit, it is one of India�s largest lakes,  at 40 mi (65 km) long and 5-13 mi (8-20 km) wide. It was once a bay  of the ocean until it was silted up by monsoon tides. Dotted with islands,  it offers good hunting, boating, and fishing.</p><p>Chiloe \,che-lo-'a\ Island, southwestern Chile. Lying some 30 mi (50 km)  off the mainland, it has an area of 3,241 sq mi (8,394 sq km). Spaniards  captured it from Indians in 1567 and controlled it until 1826, making it a  last foothold in Chile of royalist forces during the wars for independence.  Heavily forested, the island is little developed. The island�s inhabitants  make their living by agriculture, fishing, and forestry.</p><p>Chilpancingo \,chel-pan-'seq-go\ in full Chilpancingo de los  Bravos City (pop., 2000: 142,746 136,000), capital of Guerrero state,  southern Mexico. Located in the Sierra Madre del Sur, it was founded in  1591 and gained prominence as the site of the first Mexican congress,  convoked in 1813. Battles were fought there in both the war for indepen�  dence from Spain and in the Mexican Revolution. It is an agricultural cen�  tre for the surrounding region.</p><p>Chilperic Vchil-p3-rik\ I (b. c. 539�d. September or October 584,  Chelles, France) Merovingian king of Soissons. On the death of his father,  Chlotar I, he and his three half brothers divided the kingdom. Chilperic  received Soissons, the poorest share, but gained more land when one of  his brothers died. Thus Chilperic became the ruler of most of the king�  dom later known as Neustria. Ambitious, brutal, and debauched, he was  called the Nero and Herod of his age by a contemporary writer. Chilperic  murdered his own wife in order to marry his mistress, Fredegund. The  murder led to years of intrigue by family members seeking revenge and  civil war. He was finally killed, possibly at Fredegund�s orders, by an  unknown assassin. He was survived by his wife and an infant son.</p><p>Chilwa \'chil-wa. Lake Lake, southeastern Malawi. It lies in a depres�  sion southeast of Lake Malawi between the Shire Highlands and the</p><p>Mozambique border. Today it covers about 1,000 sq mi (2,600 sq km); it  was much larger when David Livingstone arrived there in 1859, and origi�  nally it filled the entire depression.</p><p>Chimborazo \,chem-bo-'ra-zo\ Mountain peak, Ecuador. The highest  peak in Ecuador, elevation 20,702 ft (6,310 m), it was once thought to be  the highest in the Andes Mountains (see Mount Aconcagua). An inactive  volcano, it is heavily glaciated. Many attempted to climb it in the 18th  and 19th centuries, but the summit was not reached until 1880, by the  English mountaineer Edward Whymper.</p><p>Chimera Vkl-'mir-oN In Greek mythology, a fire-breathing female mon�  ster. Its foreparts resembled a lion, its middle a goat, and its hindquarters  a dragon. It devastated the land around Caria and Lycia until it was killed  by Bellerophon. The word is now often used to denote a fantasy or a fig�  ment of the imagination.</p><p>chimera or chimaera \kI-'mir-3\ Any of the 28 species of ancient  fishes constituting the subclass Holocephali (class Chondrichthyes), found  in temperate to cold waters of all oceans. Like sharks and rays, chimeras  have a skeleton of cartilage rather than bone, and the males possess exter�  nal reproductive organs (claspers). They have a single external gill open�  ing, covered by a flap as in the bony fishes, on each side of the body.  Males have a supplemental clasping organ that is unique among fishes.  Chimeras have large pectoral and pelvic fins and two dorsal fins, the first  preceded by a sharp spine. They range in length from 24 to 80 in. (60 to  200 cm) and in colour from silvery to blackish. They inhabit rivers, estu�  aries, coastal waters, and open ocean to depths of 8,000 ft (2,500 m) or  more. They eat small fishes and invertebrates.</p><p>Chimkent See Shymkent</p><p>chimpanzee Species (Pan troglodytes) of great ape that inhabits the  rain forests and woodland savannas  of equatorial Africa, the closest liv�  ing relative to humans. Chimps are  3-5.5 ft (1-1.7 m) tall when stand�  ing upright, weigh 70-130 lbs  (32-60 kg), and have a brown or  black coat and a bare face. They do  most of their feeding in the trees,  swinging from branch to branch; to  move any distance they walk, usu�  ally on all fours, on the ground. They  eat mostly fruits, berries, leaves, and  seeds, some termites and ants, and  occasionally a young baboon or bush  pig. They are capable of problem  solving, tool use, and deceit. Chim�  panzees are highly social and live in  flexible groups (15-100 or more members) known as communities. In the  wild they live about 45 years, in captivity more than 50.

The Chimu state took shape in the early 14th century. It was a highly  stratified society, with a mass of peasants labouring under a ruling nobil�  ity. Its capital, Chan Chan, on the northern coast of present-day Peru, is  now a major archaeological site. The Chimu produced fine textiles and  gold, silver, and copper objects. In the 15th century they were conquered  by the Inca, who absorbed much of Chimu high culture into their own  imperial organization.</p><p>Chin dynasty See Jin dynasty, Juchen dynasty  Ch'in dynasty See Qin dynasty</p><p>Chin Hills Mountainous region, northwestern Myanmar (Burma).

The Chin Hills  vary from 7,000 to 10,000 ft (2,000 to 3,000 m) high. They and the arc  are part of the north-south-trending mountain belt of Southeast Asia, which  has hindered east-west movement; the region was populated by the Chin  peoples from the north.

Area:</p><p>3,696,100 sq mi (9,572,900 sq km). Popu�  lation (2005 est.): 1,304,369,000. Capital: Beijing. It is the world�s most  populous country, the Han (ethnic Chinese) forming more than nine-tenths  of the population. Languages: dialects of Han Chinese, Mandarin being  the most important. Religions: traditional beliefs, Buddhism, Christianity,  Islam, Daoism (all legally sanctioned). Currency: renminbi (of which the  unit is the yuan). China has several topographic regions. The southwest�  ern area contains the Plateau of Tibet, which averages more than 13,000  ft (4,000 m) above sea level; its core area, averaging more than 16,000 ft  (5,000 m) in elevation, is called �the Roof of the World� and provides the  headwaters for many of Asia�s major rivers. Higher yet are the border  ranges, the Kunlun Mountains to the north and the Himalayas to the south.  China�s northwestern region stretches from Afghanistan to the Northeast  (Manchurian) Plain. The Tien Shan (�Celestial Mountains�) separate Chi�  na�s two major interior basins, the Tarim Basin (containing the Takla  Makan Desert) and the Junggar Basin. The Mongolian Plateau contains  the southernmost part of the Gobi Desert. The lowlands of the eastern  region include the Sichuan Basin, which runs along the Yangtze River  (Chang Jiang); the Yangtze divides the eastern region into northern and  southern parts. The Tarim is the major river in the northwest. China�s  numerous other rivers include the Huang He (Yellow River), Xi, Sungari  (Songhua), Zhu (Pearl), and Lancang, which becomes the Mekong in  Southeast Asia. The country is a single-party people�s republic with one  legislative house. The chief of state is the president, and the head of gov�  ernment is the premier.</p><p>The discovery of Peking man in 1927 (see Zhoukoudian) dates the  advent of early hominins (human ancestors) to the Paleolithic Period. Chi�  nese civilization is thought to have spread from the Huang He valley. The  first dynasty for which there is definite historical material is the Shang (c.  17th century bc), which had a writing system and a calendar. The Zhou,  a subject state of the Shang, overthrew its Shang rulers in the mid-11th  century and ruled until the 3rd century bc. Daoism and Confucianism were  founded in this era. A time of conflict, called the Warring States period,  lasted from the 5th century until 221 bc. Subsequently the Qin (or Chin)  dynasty (from whose name China is derived) was established, after its  rulers had conquered rival states and created a unified empire. The Han</p><p>dynasty was established in 206 bc and ruled until ad 220. A time of tur�  bulence followed, and Chinese reunification was achieved with the found�  ing of the Sui dynasty in 581 and continued with the Tang dynasty (618�  907). After the founding of the Song dynasty in 960, the capital was moved  to the south because of northern invasions. In 1279 this dynasty was over�  thrown and Mongol (Yuan) domination began. During that time Marco  Polo visited Kublai Khan. The Ming dynasty followed the period of Mon�  gol rule and lasted from 1368 to 1644, cultivating antiforeign feelings to  the point that China closed itself off from the rest of the world. Peoples  from Manchuria overran China in 1644 and established the Qing (Man-  chu) dynasty. Ever-increasing incursions by Western and Japanese inter�  ests led in the 19th century to the Opium Wars, the Taiping Rebellion, and  the Sino-Japanese War, all of which weakened the Manchu. The dynasty  fell in 1911, and a republic was proclaimed in 1912 by Sun Yat-sen. The  power struggles of warlords weakened the republic. Under Chiang Kai-  shek some national unification was achieved in the 1920s, but Chiang  broke with the communists, who had formed their own armies. Japan  invaded northern China in 1937; its occupation lasted until 1945 (see  Manchukuo). The communists gained support after the Long March  (1934-35), in which Mao Zedong emerged as their leader. Upon Japan�s  surrender at the end of World War II, a fierce civil war began; in 1949  the Nationalists fled to Taiwan, and the communists proclaimed the Peo�  ple�s Republic of China. The communists undertook extensive reforms,  but pragmatic policies alternated with periods of revolutionary upheaval,  most notably in the Great Leap Forward and the Cultural Revolution. The  anarchy, terror, and economic paralysis of the latter led, after Mao�s death  in 1976, to a turn to moderation under Deng Xiaoping, who undertook eco�  nomic reforms and renewed China�s ties to the West. The government  established diplomatic relations with the U.S. in 1979. Since the late  1970s the economy has been moving from central planning and state-run  industries to a mixture of state-owned and private enterprises in manu�  facturing and services, in the process growing dramatically and trans�  forming Chinese society. The Tiananmen Square incident in 1989 was a  challenge to an otherwise increasingly stable political environment after  1980. In 1997 Hong Kong reverted to Chinese rule, as did Macau in 1999.</p><p>china, bone See bone china</p><p>China Sea Part of the western Pacific Ocean.

The northern section is the East China Sea, or  Eastern Sea, which covers an area of some 290,000 sq mi (751,100 sq  km), has a maximum depth of 8,912 ft (2,717 m), and is enclosed by east�  ern China, South Korea, the Japanese island of Kyushu, the Ryukyu Islands,  and Taiwan. The southern section is the South China Sea, often called  simply the China Sea, which covers an area of 1,423,000 sq mi (3,685,000  sq km), has a maximum depth of about 16,000 ft (5,000 m), and is  enclosed by southeastern China, Taiwan, the Philippines, Borneo, and  mainland Southeast Asia.</p><p>chinchilla \chin-'chi-lo\ Small South American rodent (genus Chin�  chilla, family Chinchillidae) long  valued for its extremely fine-textured  fur. Chinchillas look like long-tailed,  small-eared rabbits. They are about  14 in. (35 cm) long, including the  tufted tail. The soft fur is gray with  dusky overtones; a black streak runs  the length of the tail, above and  below. Chinchillas live in loose com�  munities in arid, rocky regions of the  Chilean and Bolivian Andes, in bur�  rows or rock crevices. They eat  seeds, fruit, grain, herbs, and moss.</p><p>Once hunted almost to extinction, they are still scarce in the wild.

It is generally navigable below  its confluence with the Uyu River. It was the scene of heavy fighting dur�  ing World War II.</p><p>Chinese cabbage Either of two widely cultivated members of the  mustard family, bok choy and Brassica pekinensis. The latter vegetable, also  called celery cabbage, forms a tight head of crinkled light green leaves.  It has long been grown in the U.S. as a salad vegetable. All Chinese cab�  bages are delicate and crisp, qualities that enable them to combine with a  wide variety of foods. Kimchi, the universal Korean pickle, is often made  with Chinese cabbage.</p><p>Chinese Communist Party (CCP) Political party founded in China  in 1921 by Chen Duxiu and Li Dazhao. It grew directly from the reform-  oriented May Fourth Movement and was aided from the start by Russian  organizers. Under Russian guidance, the CCP held its First Congress in  1921; the Russians also invited many members to the Soviet Union for  study and encouraged cooperation with the Chinese Nationalist Party. This  cooperation lasted until 1927, when the communists were expelled. CCP  fortunes declined rapidly after several failed attempts at uprisings, and  the few members that remained fled to central China to regroup, where  they formed a soviet-style government in Jiangxi. Harried by the Nation�  alist army under Chiang Kai-shek, the CCP forces undertook the Long  March to northwestern China, when Mao Zedong became the party�s  undisputed leader. War with the Japanese broke out in 1937 and led to a  temporary alliance between the CCP and the Nationalists. After World  War II, the CCP participated in U.S.-mediated talks with the Nationalists,  but in 1947 the talks were abandoned and civil war resumed. The CCP  increased its already strong rural base through land redistribution, and in  1949 it took control of mainland China. In the decades that followed,  radical members led by Mao and moderates led initially by Liu Shaoqi vied  for control of the party and the direction of China. After Mao�s death in  1976 the party moved steadily toward economic, if not political, liberal�  ization. The government�s brutal suppression of student protesters at  Tiananmen Square in 1989 produced a major shakeup in party leadership.  Today the CCP sets policy, which government officials implement. The  organs at the top of the CCP are the Political Bureau, the Political  Bureau�s Standing Committee, and the Secretariat, among which the divi�  sion of power is constantly shifting.

Candidates faced fierce competition in a series of exams  dealing primarily with Confucian texts and conducted on the prefectural,  provincial, and national levels. Despite a persistent tendency to empha�  size rote learning over original thinking and form over substance, the  exams managed to produce an elite grounded in a common body of teach�  ings and to lend credibility to claims of meritocracy. Too inflexible to be  capable of modernization, the system was finally abolished in 1905. See  also Five Classics; Four Books.</p><p>Chinese languages or Sinitic languages Family of languages  comprising one of the two branches of Sino-Tibetan. They are spoken by  about 95% of the inhabitants of China and by many communities of Chi�  nese immigrants elsewhere. Linguists regard the major dialect groups of  Chinese as distinct languages, though because all Chinese write with a  common system of ideograms, or characters (see Chinese writing system),  and share Classical Chinese as a heritage, traditionally all varieties of  Chinese are regarded as dialects. There is a primary division in Chinese  languages between the so-called Mandarin dialects�which have a high  degree of mutual intelligibility and cover all of the Chinese speech area  north of the Yangtze River (Chang Jiang) and west of Hunan and Guang�  dong provinces�and a number of other dialect groups concentrated in  southeastern China. Far more people�more than 885 million�speak a  variety of Mandarin Chinese as a first language than any other language  in the world. The northern Mandarin dialect of Beijing is the basis for  Modem Standard Chinese, a spoken norm that serves as a supradialectal  lingua franca. Important dialect groups other than Mandarin are Wu (spo�  ken in Shanghai), Gan, Xiang, Min (spoken in Fujian and Taiwan), Yue  (including Cantonese, spoken in Guangzhou [Canton] and Hong Kong),  and Kejia (Hakka), spoken by the Hakka. The modern Chinese languages  are tone languages, the number of tones varying from four in Modem  Standard Chinese to nine in some dialects.</p><p>Chinese law Law that evolved in China from the earliest times until  the 20th century, when Western socialist law (see Soviet law) was intro�  duced. The oldest extant and complete Chinese law code was compiled  in ad 653 during the Tang dynasty. Traditional Chinese law was influenced  both by Confucianism, which allowed variability in moral conduct accord�  ing to status and circumstances, and by Legalist, or Fajia, principles,  which stressed reliance on uniform objective standards. The law also was  affected by the emperor�s divine role in the universe. The emperor was  considered responsible to heaven for any disturbance in the earthly sphere;  whenever a disturbance occurred, punishment was considered a means of  restoring the cosmic equilibrium. All citizens were obliged to denounce  wrongdoers to the local magistrate�s office. The magistrate studied the  facts of a case and, using the penal code, determined punishments, includ�  ing beatings and torture. A profession of advocates, or lawyers, never  developed in China. Traditional law continued to exert influence even  after the communists gained power in China in 1949.</p><p>Chinese medicine, traditional System of medicine at least 23 cen�  turies old that aims to prevent or heal disease by maintaining or restoring  yin-yang balance. Detailed questions are asked about a patient�s illness  and such things as taste, smell, and dreams, but close examination of the  pulse, at different sites and times and with varying pressure, is paramount.  Of Chinese medicine�s numerous remedies, Western medicine has  adopted many, including iron (for anemia) and chaulmoogra oil (for lep�  rosy). Use of certain animal remedies has seriously contributed to the  endangered-species status of some animals (including tiger and rhinoc�  eros). Chinese medicine used inoculation for smallpox long before West�  ern medicine. Other practices include hydrotherapy, acupuncture, and  ACUPRESSURE.</p><p>Chinese mustard See bok choy  Chinese Nationalists See Guomindang  Chinese New Year See New Year's Day</p><p>Chinese writing system System of symbols used to write the Chi�  nese language. Chinese writing is fundamentally logographic: there is an  exact correspondence between a single symbol, or character, in the script  and a morpheme. Each character, no matter how complex, is fit into a hypo�  thetical rectangle of the same size. The Chinese script is first attested in  divinatory inscriptions incised on bone or tortoise shells dating from the  Shang dynasty. Early forms of characters were often clearly pictorial or  iconic. Shared elements of characters, called radicals, provide a means of  classifying Chinese writing. It is thought that an ordinary literate Chinese</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Ch'ing dynasty &#x25BA; Chiron I 395</p><p>person can recognize 3,000-4,000 characters. Efforts have been made to  reduce the number of characters and to simplify their form, though the  fact that they can be read by a speaker of any Chinese language and their  inextricable link with China�s 3,000-year-old culture makes abandonment  of the system unlikely. Chinese characters have also been adapted to write  Japanese, Korean, and Vietnamese.</p><p>Ch'ing dynasty See Qing dynasty  Chinggis Khan See Genghis Khan  Ch'ing-hai See Qinghai</p><p>Ch'ing-hai Hu See Koko Nor</p><p>chinoiserie \shen-'waz-re\ Fanciful European interpretations of Chi�  nese styles in the design of interiors, furniture, pottery, textiles, and gar�  dens. The expansion of trade with East Asia produced a lively vogue for  Chinese fashions in the 17th�18th centuries. The most outstanding chi�  noiserie interior was the Trianon de Porcelaine (1670-71), built for Louis  XIV at Versailles. The style featured lavish gilding and lacquering, the use  of blue and white (as in delftware), asymmetrical forms, unorthodox per�  spective, and Asian motifs. In the 19th century, the fashion gave way to  Turkish and other styles considered exotic.</p><p>Chinook \sh3-'nuk\ Northwest Coast Indian people of Washington and  Oregon, U.S. At the time of first contact, the Chinook�who were in fact  composed of several smaller groups, including the Lower Chinook, the  Clatsop, the Clackamas, and the Wasco�lived along the lower Colum�  bia River and spoke Chinookan languages. They were famous as traders,  with connections stretching as far as the Great Plains. They traded dried  salmon, canoes, shells, and slaves. Chinook Jargon, the trade language of  the Northwest Coast, was a combination of Chinook with Nootka and  other Indian, English, and French terms. The Chinook were first described  by the explorers Lewis and Clark, who encountered them in 1805. The  basic social unit was the clan. Chinook religion focused on salmon rites  and guardian spirits, and the potlatch was an important social ceremony.  Following a smallpox epidemic in the early 19th century that brought  about the collapse of Chinook culture, most of the remaining Chinook  were absorbed into other Northwest Coast groups and many were  removed to reservations. Only some 600 individuals claimed sole Chi�  nook descent in the 2000 U.S. census. In 2001 the Chinook gained fed�  eral recognition of tribal status.</p><p>chinook salmon or king salmon Prized North Pacific food and  sport fish ( Oncorhynchus tshawytscha) of the salmon family. The average  weight is about 22 lbs (10 kg), but individuals of 50-80 lbs (22-36 kg)  are not unusual. Chinook salmon are silvery, with round black spots. In  fresh water they are found from the Amur River of Asia northward and,  across the Bering Sea, southward to the Sacramento River of North  America. Their range in the open ocean extends farther south. During  spring spawning runs, adults swim as far as 2,000 mi (3,200 km) up the  Yukon River, spawn, and then die. Young chinook salmon enter the sea  when one to three years old. They were successfully introduced into Lake  Michigan, creating a new sport fishery after the virtual elimination of lake  trout by sea lampreys in the mid 20th century.</p><p>Chios Vkl-,as\ or Khios \'ke-os\ Island, Greece.

It  was noted in antiquity as Homer�s  birthplace. It was colonized by Ion-  ians and became subject to Persia in  546 bc. Though later a member of the  Delian League, it revolted several  times against Athens.

It is reddish brown with five  black stripes alternating with two brown and two white stripes. The other  species (all in the genus Eutamia) are found in western North America  and central and eastern Asia. They are smaller and have different stripe  patterns. Chipmunks are active burrow dwellers that eat primarily seeds,  berries, and tender plants. They store seeds underground, carrying them  in roomy cheek pockets.

Little is known of his  life before 1753, when he opened a showroom and workshop in London.  In 1754 he published The Gentleman and Cabinet-Maker�s Director, a  popular collection of designs illustrating almost every type of domestic  furniture.

Treatment involves  manipulations of body structures, primarily the spinal column, and use of  other techniques when necessary. It concerns the relationship between  musculoskeletal structures and functions of the body and the nervous sys�  tem. The chiropractic method was propounded in 1895 by Daniel David  Palmer (1845-1913). Practitioners are trained at accredited chiropractic  colleges.</p><p>chisel Cutting tool with a sharpened edge at the end of a metal blade,  used (often by driving with a mallet or hammer) in dressing, shaping, or  working a solid material such as wood, stone, or metal. Flint ancestors  of the chisel existed by 8000 bc; the ancient Egyptians used copper and  later bronze chisels to work both wood and soft stone. Chisels today are  made of steel, in various sizes and degrees of hardness, depending on use.</p><p>Chisholm, Shirley orig. Shirley Anita St. Hill (b. Nov. 30, 1924,  Brooklyn, N.Y., U.S.�d. Jan. 1, 2005, Ormond Beach, Fla.) U.S. poli�  tician. A graduate of Columbia University (M.A., 1952), she was a school�  teacher before becoming active in local politics. Elected to the U.S. House  of Representatives in 1968, she became the first African American woman  to serve in Congress. During her 15 years in the House, she was known  for her strong liberal views, including her opposition to U.S. involvement  in the Vietnam War and her advocacy of full-employment programs. She  cofounded the National Women�s Political Caucus. As a candidate for the  Democratic Party�s 1972 U.S. presidential nomination, she won 152 del�  egates before withdrawing from the race.</p><p>Chisholm Trail Ychiz-omX 19th-century route for cattle drives from  Texas to Kansas, probably named for the trader Jesse Chisholm (1806?-  1868?). The trail ran from south of San Antonio, across Oklahoma to  Abilene, Kan., where a railhead was established in 1867. Between 1867  and 1871 1.5 million head of cattle were driven north over the trail to be  shipped to markets in the East. After the 1880s the trail�s importance  declined as other railheads were established.</p><p>Chisinau \,ke-she-'nau\ formerly (1812-1918, 1940-91) Kishinev  Vki-shi-.nefN City (pop., 1999: 655,000), capital of Moldova. It lies on a  tributary of the Dniester River. Ruled by Moldavia in the 15th century and  taken by the Ottoman Turks in the 16th century, it was ceded to Russia  in 1812. From 1918 the city was controlled by Romania; it was ceded  back to the Soviet Union in 1940 and became the capital of the newly  formed Moldavian S.S.R. The city is a commercial centre and the site of  a university.</p><p>chitin Vkl-CnX White, homy substance found in the external skeleton of  crabs, lobsters, and many insects; in internal structures of some other  invertebrates; and in some fungi, algae, and yeasts. It is a polysaccharide,  the monomer unit being glucosamine. It is used industrially in purifying  wastewater, thickening and stabilizing foods and pharmaceuticals, and  sizing and strengthening paper, and as a wound-healing agent, an ion-  exchange resin, a membrane for industrial separations, and a binder for  dyes, fabrics, and adhesives.</p><p>Chittagong \'chi-t9-,gaq\ City (pop., 2001 prelim.: city, 2,199,590;  metro, area, 3,361,244), chief Indian Ocean port, Bangladesh. It is the  country�s second most important industrial city, with jute mills, engineer�  ing works, and a large oil refinery. Known to Arab sailors by the 10th  century ad, it was conquered by Muslims in the 14th century and occu�  pied by the governor of Bengal in the 17th century. Ceded to Britain�s  East India Company in 1760, it was constituted a municipality in 1864.  Damaged in the conflict between India and Pakistan in 1971, its port  facilities were rebuilt. It is the site of the University of Chittagong  (founded 1966).</p><p>Ch'iu Ch'u-chi See Qiu Chuji</p><p>chivalry Vshi-v3l-re\ Knightly class of feudal Europe, and especially  the gallantry and honor expected of medieval knights. The ideal of cour�  teous knightly conduct developed in the 12th-13th century. It arose out  of feudal obligation (see feudalism) and stressed loyalty and obeisance by  a knight to his God, his lord, and his lady, thus melding Christian and  military virtues. Chivalry was greatly strengthened by the Crusades, a  military endeavor on behalf of Christianity, which led to the founding of</p><p>the earliest orders of chivalry, the Knights of Malta and the Templars. In  addition to loyalty and honor, the chivalric virtues included valor, piety,  courtesy, and chastity. Questions of love and honor were combined in the  ethos of courtly love. The knight�s lady was meant to be unobtainable,  ensuring chastity; the feminine ideal thus became melded with the Virgin  Mary. In the 14th�15th century, chivalry came to be associated increas�  ingly with aristocratic display and public ceremony, particularly in joust�  ing tournaments, rather than with service in the field.</p><p>chive Small, hardy perennial plant ( Allium schoenoprcisum ) of the lily  family, related to the onion. Its small,  white, elongated bulbs and thin, tubu�  lar leaves grow in clumps. Dense,  attractive, spherical umbels of bluish  or lilac flowers rise above the foli�  age. The leaves may be cut off at  ground level and used for seasoning  foods.</p><p>Chivington Massacre See Sand  Creek Massacre</p><p>chlamydia \kl3-'mi-de-9\ Any of  the bacterial parasites that make up  the genus Chlamydia, which cause  several diseases in humans, including conjunctivitis and chlamydial pneu�  monia. One form causes a variety of sexually transmitted diseases. In men,  symptoms are similar to those of gonorrhea. In women, chlamydial infec�  tion ordinarily produces few, if any, symptoms, and most infected women  thus are unaware of their condition. However, untreated infections in  women can lead to sterility, a higher risk of premature births, and ectopic  pregnancies. Chlamydia frequently causes conjunctivitis or pneumonia in  the newborn infant. Treatment is with antibiotics.</p><p>Chlamydomonas Ykla-mo-'da-mo-nosN Genus of single-celled green  algae considered to be primitive life-forms of evolutionary significance.  The cell has a spherical cellulose membrane, an eyespot, and a cup-shaped,  pigment-containing chloroplast. Though capable of photosynthesis,  Chlamydomonas may also absorb nutrients through the cell surface. It is  found in soil, ponds, and ditches polluted by manure. It may colour water  green. A red-pigmented species turns melting snow red.</p><p>chlorella \klo-'re-l3\ Any green algae of the genus Chlorella, found in  fresh or salt water and in soil. They have a cup-shaped chloroplast. Chlo-  rellas are used often in studies of photosynthesis, in mass cultivation  experiments, and for purifying sewage wastes. Because they multiply  rapidly and are rich in proteins and in B-complex vitamins, they have been  studied as a potential food product for humans both on Earth and in outer  space. Chlorella farms, closed systems that provide humans with food,  water, and oxygen, have been established in the U.S., Japan, The Neth�  erlands, Germany, and Israel.</p><p>chlorine Nonmetallic chemical element, chemical symbol Cl, atomic  number 17. It is a toxic, corrosive, greenish yellow GAS (as the diatomic  molecule Cl 2 ) that severely irritates the eyes and respiratory system (and  was used for that purpose as a chemical-warfare agent in World War I). As  the chloride ion and in the hypochlorite ion, it has valence 1 ; in the chlo�  rite, chlorate, and perchlorate ions, it has higher valences. Chlorine and  its compounds are important industrial materials with myriad uses in the  manufacture of other chlorinated compounds (e.g., PVC, hydrochloric acid,  ethylene dichloride, trichloroethylene, PCBs), in water purification  (municipal systems, swimming pools), in textile industries, in flame retar�  dants, in special batteries, and in food processing. Sodium chloride (table  salt) is by far the most familiar of its compounds. See also bleach.</p><p>chlorite Widespread group of layer silicate minerals composed of  hydrous aluminum silicates, usually of magnesium and iron. The name,  from the Greek for �green,� refers to chlorite�s typical colour. Chlorites  have a silicate layer structure similar to that in micas. They characteris�  tically occur as alteration products of other higher temperature minerals  and are most common in sedimentary and igneous rocks and in some  metamorphic rocks.</p><p>chloroethylene See vinyl chloride</p><p>chlorofluorocarbon (CFC) Any of several organic compounds con�  taining carbon, fluorine, chlorine, and hydrogen.

How�  ever, CFCs released into the atmosphere rise into the stratosphere, where  solar radiation breaks them down; the chlorine released reacts with ozone,  depleting the ozone layer. In 1992 most developed countries agreed to end  CFC production by 1996; 1997 production, weighted according to the  ozone depletion potential of each CFC, was 10% of peak (1988) produc�  tion.</p><p>chloroform Clear, colourless, heavy, nonflammable liquid organic  compound with a pleasant etherlike odour, chemical formula CHC1 3 . It  was the first substance successfully used as a surgical anesthetic (1847);  being somewhat toxic, it has been increasingly displaced by other sub�  stances for this purpose. It has some industrial uses, primarily as a solvent.</p><p>chlorophyll Any member of one of the most important classes of pig�  ment molecules involved in photosynthesis. Found in almost all photosyn�  thetic organisms, it consists of a central magnesium atom surrounded by  a nitrogen-containing structure called a porphyrin ring, to which is attached  a long carbon-hydrogen side chain, known as a phytol chain. In structure  it is remarkably similar to hemoglobin. Chlorophyll uses energy that it  absorbs from light to convert carbon dioxide to carbohydrates. In higher  plants it is found in chloroplasts.</p><p>chloroplast Microscopic, ellipsoidal organelle in a green plant cell. It  is the site of photosynthesis. It is distinguished by its green colour, caused  by the presence of chlorophyll. It contains disk-shaped structures called  thylakoids that make possible the formation of ATP, an energy-rich stor�  age compound.</p><p>Internal structures of the chloroplast. The interior contains flattened sacs of photo�  synthetic membranes (thylakoids) formed by the invagination and fusion of the  inner membrane. Thylakoids are usually arranged in stacks (grana) and contain the  photosynthetic pigment (chlorophyll). The grana are connected to other stacks by  simple membranes (lamellae) within the stroma, the fluid proteinaceous portion con�  taining the enzymes essential for the photosynthetic dark reaction, or Calvin cycle.</p><p>� MERRIAM-WEBSTER INC.</p><p>Chlotar \'klo-,tar\ I (b. c. 500?�d. late 561, Compiegne, Fr.)

The youngest son of Clovis I, he shared  in the partition of his father�s kingdom in 511 and extended his lands by  murder and intrigue. He launched campaigns against the Burgundians  (523, 532-34), the Visigoths (532, 542), and the Thuringians (c. 531).

It is con�  sumed as candy, used to make beverages, and added as a flavouring or  coating for confections and baked products. It was introduced to Europe  by Hernan Cortes following his visit in 1519 to the court of Montezuma</p><p>II. who served the conquistador a bit�  ter cacao-bean drink, xocoatl. In  making chocolate, the kernels of fer�  mented and roasted cacao beans are  ground into a paste called chocolate  liquor, which may be hardened in  molds to form baking (bitter) choco�  late, pressed to reduce the cocoa but�  ter (vegetable fat) content and then  pulverized to make cocoa powder, or  mixed with sugar and additional  cocoa butter to make sweet (eating)  chocolate. The addition of concen�  trated milk to sweet chocolate pro�  duces milk chocolate. White  chocolate, made from cocoa butter,  sugar, milk, and vanilla, contains no  cocoa solids. Rich in carbohydrates  and fat and containing small  amounts of caffeine, chocolate is an  excellent source of quick energy.</p><p>Choctaw North American Indian people living in Oklahoma, U.S. They  speak a Muskogean language that is closely related to that of the Chick�  asaw. The Choctaw once lived in what is now southeastern Mississippi.  They were the most skillful of the southeastern farmers, usually having  surplus produce to sell or trade. They fished, gathered nuts and wild fruits,  hunted deer and bear, and planted com, beans, and pumpkins. Their prin�  cipal religious ceremony was the Busk (Green Corn) festival, a first-fruits  and new-fire rite celebrated at midsummer. In the 19th century, pressure  by white cotton-growers forced them to cede five million acres, and most  Choctaw were removed to Oklahoma. Some 87,300 individuals claimed  sole Choctaw descent in the 2000 U.S. census.</p><p>Ch'oe Si-hydng Vchoe-�se-'yoqV (b. 1827, Korea�d. 1898, Seoul) Sec�  ond leader of the Korean Tonghak (now Ch'ondogyo) religion. He orga�  nized the underground network that spread the apocalyptic, antiforeign  Tonghak sect following the execution of its founder, Ch�oe Che-u (1824-  64). He published the first two Tonghak scriptures in 1880 and 1881, add�  ing public service to the founder�s principle of human equality and  obligation to serve heaven. Preaching the need for Korea to become as  strong as Western imperialist powers, in 1894 he led the Tonghak Upris�  ing, which was viciously suppressed. He was arrested and executed in  1898, by which time Tonghak had spread throughout Korea.</p><p>choir Body of singers with more than one voice to a part. For many cen�  turies, church choirs sang only plainsong (see Gregorian chant). The rela�  tive complexity of early polyphony required solo voices rather than choral  performance, but by the 15th century polyphony was being performed  chorally. The growth of the secular choir (or chorus) coincided with the  beginnings of opera. An oratorio choir is part of a different tradition,  which stems from the augmented church choirs used to provide choral  portions of a given oratorio, whether performed in or out of church.</p><p>Choiseul \shwa-'z3l\, Etienne-Francois de Choiseul, duke de</p><p>(b.

After serving as ambassador to the Vatican (1753-57) and to the  Austrian court, he was made a duke and named minister of foreign affairs  (1758), in which position he came to dominate the government of Louis  XV. In 1761 he concluded a military alliance with Spain (the �Family  Compact�), and at the end of the Seven Years� War he negotiated the best  terms for a defeated France. He rebuilt France�s military strength but was  dismissed from office in 1770 for advocating war against Britain.</p><p>chokecherry One of several varieties of shrub or small tree (.Prunus  virginiana ) of the rose family, native to North America. Though it is aptly  named for the astringent, acidic taste of its reddish cherries, its fruit may  be made into jelly and preserves. The stones and wilted foliage are poi�  sonous. The trees often form dense thickets on moist soils. They are fre�  quently attacked and defoliated by eastern tent caterpillars. Foul-scented  white flowers are produced in hanging spikes, and the slender brown twigs  also have an unpleasant odour and a bitter taste.</p><p>cholera Vka-b-roX Acute bacterial infection with Vibrio cholerae, caus�  ing massive diarrhea with severe depletion of body fluids and salts.

The bacteria secrete a toxin that causes the diar�  rhea, which along with vomiting leads to dehydration, with severe muscle  cramps and intense thirst. Stupor and coma may precede death by shock.  With fluid and salt replacement, the disease passes in two to seven days,  sooner if antibiotics are taken the first day. Prevention requires good sani�  tation, especially clean drinking water.</p><p>cholesterol Waxy organic compound found in blood and all animal tis�  sues. It is a steroid, with molecular formula C 27 H 46 0, containing four  rings in its structure. Cholesterol is essential to life; it is a primary com�  ponent of CELL membranes and a starting or intermediate material from which  the body makes bile acids, other steroid hormones, and vitamin D. It is made  in the liver and some other organs, in greater or lesser amounts depend�  ing on the amount recently consumed in the diet. It circulates in the blood  in compounds called lipoproteins, since it is not water-soluble alone.  Excess cholesterol in the blood forms deposits in arteries (see arterioscle�  rosis), which can lead to coronary heart disease. Michael Brown (born  1941) and Joseph Goldstein (bom 1940) won a Nobel Prize in 1985 for  their work in discovering this process. Since the body makes cholesterol  from FATS, blood cholesterol cannot be reduced by limiting only the  amount of cholesterol in the diet; the amount of fat, especially saturated  fat (see saturation, fatty acid) must also be reduced. See also triglyceride.</p><p>choline Vko-,len\ Organic compound related to vitamins in its activity.  It is important in metabolism as a component of the lipids that make up cell  membranes and of acetylcholine. It is also important as a source of chemi�  cal raw materials for cells and in transport of fats from the liver. It is usu�  ally classified with the B vitamins (see vitamin B complex) because it  resembles them in function and in its distribution in foods. In humans it  is interconvertible with certain other compounds, such as methionine, so  deficiency does not lead to disease, but some other animals need it in their  diet. Choline has various uses in medicine, nutrition, and the processing  of foods and feeds.</p><p>cholla Ych6i-ya\ Any cactus of the genus Opuntia, native to North and  South America, having needlelike  spines partly enclosed in a papery  sheath. Chollas vary greatly in size  and have small flowers, sometimes  chartreuse and inconspicuous, but  usually of more striking colors. O.  leptocaulis, the desert Christmas cac�  tus, bears bright red fruits through the  winter. Living plants serve as food  for desert animals. Cholla wood, a  hollow cylinder with regularly  spaced holes, is used for fuel and  novelties. Some cholla fruit is edible.</p><p>Chomsky, (Avram) Noam (b.</p><p>Dec. 7, 1928, Philadelphia, Pa.,</p><p>U.S.) U.S. linguist, philosopher, and  political activist. He received a Ph.D.  in linguistics from the University of  Pennsylvania in 1955, the same year  he joined the faculty at the Massa�  chusetts Institute of Technology (MIT). Chomsky takes the proper object  of study for linguistics to be the mentally represented grammars that con�  stitute the native speaker�s knowledge of his language and the biologi�  cally innate language faculty, or �universal grammar,� that enables the  developmentally normal language learner, as a child, to construct a gram�  mar of the language to which he is exposed. For Chomsky, the ultimate  goal of linguistic science is to develop a theory of universal grammar that  provides a descriptively adequate grammar for any natural language given  only the kind of �primary linguistic data� available in the social environ�  ments of children. This imperative has motivated the gradual refinement  of Chomskyan linguistic theory from the early transformational grammar  of the 1950s and �60s to the Minimalist Program of the 1990s and beyond.  A self-described libertarian socialist, Chomsky has written numerous  books and lectured widely on what he considers the antidemocratic char�  acter of American capitalism and its pernicious influence on the country�s  politics and foreign policy, mass media, and academic and intellectual  culture.

Its basic principle that �man  and God are one� is realized through faith in the unity of one�s body and  spirit and in the universality of God. Converts are instructed to meditate  on God, pray upon leaving and entering home, dispel harmful thoughts,  and worship God in church on Sundays. Ch�oe Che-u (1824-64) estab�  lished the religion in 1860 after receiving inspiration from the Heavenly  Emperor (Ch�ongju). His efforts at social change led to his execution. His  successor, Ch'oe Si-hyong, was executed following the Tonghak Uprising.

The municipality is bordered by Sichuan, Shaanxi, Hubei, Hunan,  and Guizhou provinces and has an area of 31,700 sq mi (82,000 sq km).  The leading river port and industrial centre of the region, Chongqing  (�Double-Blessed�) lies at the confluence of the Yangtze (Chang) and  Jialing rivers. In the 11th century bc it was a feudal state under the Xi  (Western) Zhou dynasty. Over the next several centuries its status alter�  nated from being ruled by an empire in northern China to being an inde�  pendent state. It finally came under Chinese rule in the Ming dynasty,  continuing under the Qing dynasty. It was opened to foreign trade in 1890.  It played a large role in the revolution of 1911. Once a city of narrow and  irregular streets, Chongqing changed greatly as a result of a moderniza�  tion program introduced during World War II, when it became the capital  of Nationalist China. Since the war it has become an important industrial  centre. It is home to Chongqing University (founded 1929).</p><p>Chons See Khons</p><p>Chopin \sho-'pa n ,\ English \ 'sh6-,pan\, Frederic (Francois) orig.  Fryaeryk Franciszek Szopen</p><p>(b.

Born to middle-  class French parents in Poland, he  published his first composition at age  seven and began performing in aris�  tocratic salons at eight. He moved to  Paris in 1831, and his first Paris con�  cert the next year thrust him into the  realm of celebrity. Renowned as a  piano teacher, he spent his time in  the highest society. He contracted  tuberculosis apparently in the 1830s.</p><p>In 1837 he began a 10-year liaison  with the writer George Sand; she left  him in 1847, and a rapid decline led  to his death two years later. Chopin  stands not only as Poland�s greatest  composer but perhaps as the most  significant composer in the history of  the piano; he exhaustively exploited  the instrument�s capacities for charm, excitement, variety, and timbral  beauty. His innovations in fingering, his use of the pedals, and his gen�  eral treatment of the keyboard were hightly influential. Apart from two  piano concertos (both 1830) and four other works for piano and orches�  tra, virtually all his compositions are for solo piano; they include some  60 mazurkas, 27 etudes, 26 preludes, 21 nocturnes, some 20 waltzes, 16  polonaises, 4 ballades, 4 scherzos, and 3 sonatas.</p><p>Chopin \sho-'pan\, Kate orig.

All  chordates, at some time in their life cycle, possess a dorsal supporting rod  (notochord), gill slits, and a dorsal nerve cord. Unlike vertebrates, tuni�  cates and cephalochordates lack any kind of brain or skeleton. Chordate  bodies consist of a body wall encasing a gut, with a space between called  the coelom. The body is usually long and bilaterally symmetrical, with  the mouth and sense organs at the front end.</p><p>chorea \ko-'re-3\ Neurological disorder causing irregular, involuntary,  purposeless movements. It is believed to be caused by degeneration of the  basal ganglia in the cerebral cortex. Sydenham chorea (St. Vitus dance)  is usually associated with rheumatic fever. It usually occurs between ages  5 and 15, more often in girls. Typical jerking movements, mostly in the  extremities and face, may affect speech and swallowing and range from  mild to incapacitating; attacks last several weeks and recur frequently.  Senile chorea, a progressive disease resembling Sydenham chorea, usu�  ally occurs late in life. Huntington chorea is rare, hereditary, and fatal. It  usually begins between ages 35 and 50 and progresses to random, often  violent, and eventually totally incapacitating spasms, absent only during  sleep. Mental deterioration begins later, and death occurs in 10-20 years.  There is no effective therapy. Children of those afflicted have a 50%  chance of developing the illness.</p><p>choreography Art of creating and arranging dances. The word is  derived from the Greek for �dance� and �write,� reflecting its early mean�  ing as a written record of dances. By the 19th century the term was used  mainly for the creation of dances, and the written record became known  as dance notation. In the 16th century dance masters at the French court  arranged their social dances into specific patterns. In the 17th century such  dances became more complex and were performed as theatrical ballets by  trained professionals. In the late 18th century Jean-Georges Noverre and  Gasparo Angiouni introduced choreography that combined expressive  mime and dance steps to produce the dramatic ballet. This was further  developed in 19th-century Romantic ballets by Marius Petipa, Jules Perrot,  and August Bournonville. Radical change in the 20th century began with  choreographers of the Ballets Russes, including Michel Fokine and Leonide  Massine, and continued with George Balanchine, Martha Graham, Freder�  ick Ashton, Jerome Robbins, Merce Cunningham, and Twyla Tharp. See also  Alvin Ailey; Agnes de Mille; Serge Lifar; Bronislava Nijinska; Salvatore  Vigano.</p><p>chorus In theatre, a group of actors, singers, or dancers who perform as  an ensemble to describe and comment on a play�s action. Choral perfor�  mances, which originated in the singing of dithyrambs in honour of  Dionysus, dominated Greek drama until the mid-5th century bc, when  Aeschylus added a second actor and reduced the chorus from 50 to 12 per�  formers. As the importance of individual actors increased, the chorus  gradually disappeared. It was revived in modern plays such as Eugene  O'Neill�s Mourning Becomes Electra (1931) and T.S. Eliot�s Murder in  the Cathedral (1935). Choruses of singers and dancers came to be fea�  tured in musical comedies, especially in the 20th century, first as enter�  tainment and later to help develop the plot.</p><p>Choshu Vcho-.shtU Japanese han (domain) that, along with the han of  Satsuma, supported the overthrow of the Tokugawa shogunate (see  Tokugawa period) and the creation of a new government headed by the  emperor.

Jan. 11, 1934, Shawinigan, Quebec, Can.) Canadian  prime minister (1993-2003). The 18th of 19 children of a working-class  family, Chretien studied law at Laval University and was called to the bar  in Quebec in 1958. He served in the Canadian House of Commons (1963�  86) and held various posts in the administrations of Lester Pearson and  Pierre Trudeau, including minister of finance (1977), the first French Cana�  dian to hold the office. In 1986, after losing the leadership battle to suc�  ceed Trudeau, he retired from parliament. Four years later he was  reelected to the House of Commons and became leader of the Liberal Party  of Canada. In 1993 the Liberals won a landslide victory, and Chretien  became prime minister. Under his leadership the party was again victo�  rious in 1997 and 2000. As prime minister, he oversaw in 1998 the pas�  sage of the country�s first balanced budget since 1970, and he pursued  progressive social reforms, drafting a law in 2003 that would recognize  same-sex marriages. Chretien�s relationship with the U.S. was sometimes  tense, and he refused to commit Canadian troops to the U.S.-led war  against Iraq in 2003.</p><p>Chretien de Troyes \kra-'tya n -d9- , trwa\ (fl. 1165-80) French poet.  Little is known of his life. He is the author of the five Arthurian romances  Erec, Cliges, Lancelot , Yvain, and Perceval and possibly also of a non-  Arthurian tale. Written in the vernacular, his romances were derived from  the writings of Geoffrey of Monmouth and combine separate adventures  into well-knit stories. They were imitated almost immediately by other  French poets and were translated and adapted frequently as the romance  continued to develop as a narrative form.

It is the country�s second larg�  est city and an important industrial centre; its port is Lyttelton. Called the  �Garden City of the Plains� for its numerous parks and gardens, it is home  to the University of Canterbury, Christ�s College, and Lincoln University.</p><p>Christian II (b. July 1, 1481, Nyborg, Den.�d. Jan. 25, 1559, Kalund-  borg) King of Denmark and Norway (1513-23) and of Sweden (1520-  23). He succeeded his father, John, as king of Denmark and Norway. In  1517 he invaded Sweden, defeating the forces of the Swedish regent, and  was crowned Sweden�s king in 1520. However, he ordered a massacre of  Swedish nobles (the Stockholm Bloodbath) that helped incite a success�  ful Swedish war for independence, marking the end of the Kalmar Union  in 1523. That year a revolt in Denmark forced Christian to flee to the  Netherlands. After attempting to regain his kingdom, he was arrested by  Danish forces in 1532 and spent the rest of his life imprisoned in Danish  castles.</p><p>Christian III (b. Aug. 12, 1503, Gottorp, Schleswig�d. Jan. 1, 1559,  Kolding, Den.) King of Denmark and Norway (1534-59). Son of King  Frederick I, he assumed control of the kingdom after winning a civil war  known as the Count�s War. He arrested the Catholic bishops who had  opposed him and organized the Diet of Copenhagen (1536), which con�  fiscated episcopal property and established the state Lutheran church. By  forming close ties between the church and the crown, he laid the foun�  dation for the absolutist Danish monarchy of the 17th century.</p><p>Christian IV (b. April 12, 1577, Frederiksborg Castle, Hillerpd,  Den.�d. Feb. 28, 1648, Copen�  hagen) King of Denmark and Nor�  way (1588-1648). He succeeded to  the throne on the death of his father,</p><p>Frederick II, but a regency ruled  until 1596. After his coronation he  succeeded in limiting the powers of  the Rigsrad (state council). He led  two unsuccessful wars against Swe�  den and brought disaster to his coun�  try by leading it into the Thirty Years'</p><p>War. He was eventually forced to  accept the increased power of the  nobility, which had long opposed his  warlike policies. However, he ener�  getically promoted trade and ship�  ping, was a great builder and founder  of cities, left a national heritage of  fine buildings, and was considered  one of the most popular of Danish  kings.</p><p>Christian IX (b. April 8, 1818,</p><p>Gottorp, Schleswig�d. Jan. 29,</p><p>1906, Copenhagen, Den.) King of  Denmark (1863-1906). He suc�  ceeded the childless Frederick VII, whose cousin he had married. When he  became king, he was forced by popular feeling to sign the November  Constitution, which incorporated Schleswig into the state (see Schleswig-  Holstein Question). This led to the disastrous war of 1864 against Prussia  and Austria. After the war, he unsuccessfully resisted the advance of full  parliamentary government in Denmark.</p><p>Christian X (b. Sept. 26, 1870, Charlottenlund, Den.�d. April 20,  1947, Copenhagen) King of Denmark (1912�47) who symbolized his  nation�s resistance to the German occupation in World War II. He assumed  the throne on the death of his father, Frederick VIII (1843-1912). In 1915  Christian signed a constitution granting equal suffrage to men and women.  After the German occupation began in 1940, he rode frequently on horse�  back through the streets of Copenhagen, showing that he had not aban�  doned his claim to national sovereignty, and he opposed Nazi demands  for anti-Jewish legislation. His speech against the occupation forces in  1943 led to his imprisonment until the end of the war.</p><p>Christian, Charlie orig. Charles Christian (b. July 29, 1916, Bon�  ham, Texas, U.S.�d. March 2, 1942, New York, N.Y.) U.S. guitarist.  Christian grew up in Oklahoma City, Okla., and joined Benny Goodman  to perform in both big-band and small-group settings in 1939. He created  a sensation through his technically adept and innovative use of amplifi�  cation, thus changing the guitar�s primary role from accompanist to solo�  ist. He was the first great electric guitarist in jazz. As one of the most  advanced and influential soloists of the swing era, Christian participated  in the jam sessions at Minton�s Playhouse in Harlem with Thelonious  Monk and Dizzy Gillespie that pioneered the harmonic advances of bebop.</p><p>Christian caste In India, social stratification among Christians based on  caste membership at the time of an individual�s or an ancestor�s conver�  sion. Indian Christians are grouped by denomination, geography, and caste.  The Syrian Christians along the Malabar coast, descended from lst-century  converts of high birth, retain mid-rank status in Hindu society. Portuguese  missionaries of the 16th century converted lower-caste fisherfolk. Mission�  aries in the 19th century insisted on social reform and tended to draw from  the lowest classes. Caste distinctions are breaking down at about the same  rate among contemporary Indian Christians and other Indians.</p><p>Christian Democracy Political movement that has a close associa�  tion with Roman Catholicism and its philosophy of social and economic  justice. It incorporates both traditional church and family values and pro�  gressive values such as social welfare. After World War II, a number of  Christian Democrat parties appeared in Europe, including the Italian  Christian Democratic Party, the French Popular Republican Movement, and  the most successful, the German Christian Democratic Union. The same  period also saw the appearance of Christian Democrat parties in Latin  America. Though most were small splinter groups, Christian Democrats  eventually achieved power in Venezuela, El Salvador, and Chile.</p><p>Christian Democratic Party (Italy) See Italian Popular Party</p><p>Christian Democratic Union (CDU) German political party advo�  cating a free-market economy, limited social-welfare programs, and close  relations with the United States.

It held power from the establishment of the West German republic  in 1949 until 1969. It regained power in 1982 under Helmut Kohl, who  remained chancellor until 1998. In 1990 Kohl oversaw the reunification  of Germany. The party is a strong supporter of European integration.

Like other  Christian churches, Christian Science subscribes to an omnipotent God  and the authority (but not inerrancy) of the Bible and takes the Crucifix�  ion and Resurrection of Jesus as essential to human redemption. It departs  from traditional Christianity in considering Jesus divine but not a deity  and in regarding creation as wholly spiritual. Sin denies God�s sovereignty  by claiming that life derives from matter. Spiritual cure of disease is a  necessary element of redemption from the flesh and one of the church�s  most controversial practices. Most members refuse medical help for dis�  ease, and members engaged in the full-time healing ministry are called  Christian Science practitioners. Elected readers lead Sunday services  based on readings from the Bible and Eddy�s Science and Health with  Key to the Scriptures. At the end of the 20th century, the church had about  2,500 congregations in 70 countries; its headquarters is at the Mother  Church in Boston.

Christian socialists attempted to combine the  fundamental aims of socialism with the religious and ethical convictions  of Christianity, promoting cooperation over competition as a means of  helping the poor. The term was coined in Britain in 1848 after the failure  of the reform movement known as Chartism. Christian socialism found  followers in France and Germany, though the German group, led by Adolf  Stoecker, combined its activities with violent anti-Semitism. Although the  movement died out in the U.S. in the early 20th century, it retains an  important following in Europe.</p><p>Christiania See Oslo</p><p>Christianity Religion stemming from the teachings of Jesus in the 1st  century ad. Its sacred scripture is the Bible, particularly the New Testament.  Its principal tenets are that Jesus is the Son of God (the second person of  the Holy Trinity), that God�s love for the world is the essential component  of his being, and that Jesus died to redeem humankind. Christianity was  originally a movement of Jews who accepted Jesus as the Messiah, but the  movement quickly became predominantly Gentile. The early church was  shaped by St. Paul and other Christian missionaries and theologians; it  was persecuted under the Roman Empire but supported by Constantine I,  the first Christian emperor. In medieval and early modern Europe, Chris�  tian thinkers such as St. Augustine, Thomas Aquinas, and Martin Luther  contributed to the growth of Christian theology, and beginning in the 15th  century missionaries spread the faith throughout much of the world. The  major divisions of Christianity are Roman Catholicism, Eastern Orthodoxy,  and Protestantism. Nearly all Christian churches have an ordained clergy,  members of which are typically though not universally male. Members  of the clergy lead group worship services and are viewed as intermedi�  aries between the laity and the divine in some churches. Most Christian  churches administer two sacraments, baptism and the Eucharist. In the  early 21st century there were more than two billion adherents of Chris�  tianity throughout the world, found on all continents.</p><p>Christie, Dame Agatha (Mary Clarissa) (b.

After 10 years of rule, she</p><p>stunned Europe by abdicating the  throne, claiming that she was ill and  that the burden of ruling was too  heavy for a woman. Her real reasons  were her aversion to marriage and  her secret conversion to Roman  Catholicism, which was proscribed  in Sweden. She moved to Rome and  subsequently attempted, without  success, to gain the crowns of Naples  and Poland. One of the wittiest and  most learned women of her age, she  was a lavish patroness of the arts and  an influence on European culture.</p><p>Christine de Pisan or Chris�  tine de Pizan \kres-'ten-do-pe-  'za n \ (b. 1364, Venice�d. c. 1430)</p><p>French writer.

Some works, both poetry and prose,  champion women, notably The Book of the City of Ladies (1405). She  also wrote a life of Charles V and Le Ditie de Jehanne d�Arc (1429),  inspired by Joan of Arc�s early victories.</p><p>Christmas Christian festival celebrated on December 25, commemo�  rating the birth of Jesus. December 25 had already been identified by Sex�  tus Julius Africanus in ad 221 as the day on which Christmas would be  celebrated, and it was celebrated in Rome by ad 336. During the Middle  Ages Christmas became extremely popular, and various liturgical cel�  ebrations of the holiday were established. The practice of exchanging gifts  had begun by the 15th century. The Yule log, cakes, and fir trees derive  from German and Celtic customs. Christmas today is regarded as a fam�  ily festival with gifts brought by Santa Claus (see St. Nicholas). As an  increasingly secular festival, it has come to be celebrated by many non-  Christians.</p><p>Christmas tree Evergreen tree, usually decorated with lights and orna�  ments, to celebrate the Christmas season. The use of evergreen trees,  wreaths, and garlands as symbols of eternal life was common among the  ancient Egyptians, Chinese, and Hebrews. The Christian symbol can be  traced to a German medieval play about Adam and Eve, which included  the �paradise tree,� hung with apples. The modem, decorated version was  widespread among German Lutherans by the 18th century. Brought to  North America by German settlers in the 17th century, it had become  widespread there by the mid-19th century. It was popularized in 19th-  century England by Victoria�s consort, the German Prince Albert of Saxe-  Coburg.</p><p>Christo orig. Christo Javacheff (b. June 13, 1935, Gabrovo, Bulg.)  Bulgarian-born U.S. environmental artist. After attending Sofia�s Fine  Arts Academy, he moved to Paris in 1958, where he invented empaque-  tage, the wrapping of objects in various materials as art. He began with  cans and bottles, and eventually his projects expanded to buildings and  landscapes. In 1964 he moved to New York City. He is noted for such  monumental outdoor projects as Valley Curtain (1970-72) in Rifle Gap,  Colo., and Running Fence (1972�76) in Marin and Sonoma counties,  Calif. In 1995 he wrapped the Berlin Reichstag in metallic silver fabric.  Though his displays, which are temporary and involve hundreds of work�  ers, are controversial among environmentalists, they have been critically  well received. Since 1961 most have been collaborative efforts with his  wife, Jeanne-Claude (b. 1935).</p><p>Christopher, Saint (fl. 3rd century; Western feast day July 25; East�  ern feast day May 9) Patron saint of travelers and motorists. He is said to  have been martyred in Lycia under the Roman emperor Decius (c. 250).  Legends depict him as a giant who devoted his life to carrying travelers  across a river. One day a small child asked to be transported, and in the  middle of the river the child became so heavy that Christopher staggered  under the burden. The child revealed that the saint had been carrying  Christ and the sins of the world, thus giving rise to Christopher�s name  (Greek: �Christ-Bearer�). His historicity is doubtful.</p><p>Agatha Christie, 1946.</p><p>UPI/CORBIS-BETTMANN</p><p>Christina, engraving by Cornelis Viss-  cher, 1650.</p><p>COURTESY OF THE SVENSKA PORTRATTARKIVET,  STOCKHOLM</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>402 I Christus &#x25BA; chronicle play</p><p>Christus Vkris-tiBsV Petrus (b. c. 1420, Baerle, Brabant�d. 1472/73,  Bruges) Flemish painter.

Christus is known  for his sensitive portraits, but his most important contributions were the  introduction of geometric perspective to Netherlandish painting, and his  genrelike treatment of religious subjects, seen in works such as St. Eligius  as a Goldsmith (1449) and Virgin and Child in a Domestic Interior (c.</p><p>1450-60).</p><p>chromaticism \kro-'ma-t9- l si-z9m\ In music, the use of all 12 tones,  especially for heightened expressivity. A standard key or mode principally  employs 7 tones, leaving 5 tones for discretionary use. Use of all 12 tones  in a given piece increased in the 18th and 19th centuries. Strictly con�  trolled chromaticism, as in the ornamentation of Frederic Chopin, did not  threaten the perception of tonality. However, from the mid-19th century  on, complaints were heard with ever greater frequency that it was difficult  to perceive what a given piece�s tonal centre was, the chromaticism in the  works of Richard Wagner being the most notorious. The virtual breakdown  in tonality in the works of advanced composers led to the free atonality of  Arnold Schoenberg and his followers in the early 20th century.</p><p>chromatography V.kro-mo-'ta-gro-feN Method first described in 1903  by Mikhail S. Tsvet for separating mixed chemical substances. Tsvet�s  neglected work, rediscovered in the 1930s, uses the different affinities of  substances in a solution in a mobile phase (a moving stream of gas or liq�  uid) for adsorption onto a stationary phase (a fine-grained solid, a sheet  of filtering material, or a thin film of a liquid on a solid surface). Choices  of materials for these phases allow enormous versatility for separating  substances including biological fluids (e.g., amino acids, steroids, carbo�  hydrates, pigments), chemical mixtures, and forensic samples. In the origi�  nal technique, an organic solvent flowed through a column of powdered  alumina (see aluminum), sodium carbonate, or even powdered sugar to  separate mixed plant pigments. Among current adaptations are paper chro�  matography (PC), THIN-LAYER chromatography (TLC), liquid chromatography  (LC, including high-performance liquid chromatography, or HPLC), and  gas chromatography (GC). Some remain laboratory techniques, but oth�  ers (especially HPLC) can be used on an industrial scale. They require  different methods for detecting and identifying the separated components,  including colorimetry, spectrophotometry, mass spectrometry, and measure�  ment of fluorescence, ionization potential, or thermal conductivity. A.J.P.  Martin shared a 1952 Nobel Prize for developing LC and PC, and in his  Nobel lecture announced the development (with his cowinner R.L.M.

Chromite is commonly found as brittle masses in peridotites, serpentines,  and other basic igneous and metamorphic rocks. The principal producing  areas are South Africa, Russia, Albania, the Philippines, Zimbabwe, Tur�  key, Brazil, India, and Finland.</p><p>chromium Metallic chemical element, one of the transition elements,  chemical symbol Cr, atomic number 24. A hard, steel-gray metal that takes  a high polish, it is used in alloys (e.g., ferrochromium, steel, stainless  steel) to increase strength and corrosion resistance. It usually has valence  2, 3, or 6 and always occurs combined with other elements, especially  oxygen; chromite is its only commercial source. Various coloured gem�  stones (e.g., ruby, emerald, serpentine) owe their colour to chromium.  Sodium chromate and dichromate are used in leather tanning, in metal  surface treatment, and as catalysts. Chromium trioxide is used in chrome  plating and as a colorant for ceramics. Chromium oxide, lead chromate,  and various other chromium compounds are used as pigments. Chromium  dioxide, strongly magnetic, is used in recording tapes and as a catalyst.</p><p>chromodynamics See quantum chromodynamics</p><p>chromosomal disorder Syndrome caused by chromosome abnormal�  ity. Normally, humans have 23 pairs of chromosomes, including one pair  of sex chromosomes. Any variation from this pattern causes abnormalities.  A chromosome may be duplicated (trisomy) or absent (monosomy); one  or more extra full sets of chromosomes can be present (see ploidy); or part  of a chromosome may be missing (deletion) or transferred to another  (translocation). Resulting disorders include Down's syndrome, mental  retardation, heart malformation, abnormal sexual development, malignan�  cies, and sex-chromosome disorders (e.g., Turner's syndrome, Klinefelter's  syndrome). Chromosomal disorders occur in 0.5% of births; many can now  be diagnosed before birth by amniocentesis.</p><p>chromosome Microscopic, threadlike part of a cell that carries heredi�  tary information in the form of genes. The structure and location of chro�  mosomes differentiate prokaryotic cells from eukaryotic cells (see  prokaryote, eukaryote). Every species has a characteristic number of chro�  mosomes; humans have 23 pairs (22 pairs of autosomal, or nonsex, chro�  mosomes and one pair of sex chromosomes). Human chromosomes  consist primarily of DNA. During cell division (see meiosis, mitosis), chro�  mosomes are distributed evenly among daughter cells. In sexually repro�  ducing organisms, the number of chromosomes in somatic (nonsex) cells  is diploid, while gametes or sex cells (egg and sperm) produced by mei�  osis are haploid (see ploidy).

To meet the criteria of CFS, the  syndrome must be new, with a definite point of onset, and must persist more  than six months. Once dismissed as imaginary, CFS remains controversial.  Many authorities question whether it is a distinct disorder, since there is  considerable overlap with other conditions such as fibromyalgia and Gulf  War syndrome. No diagnostic test for CFS exists. Although a number of  theories about the cause of CFS have been advanced, none has been  proved. No cure has been found, but most patients improve gradually.</p><p>chronicle play or history play Play with a theme from history that  often holds up the past as a lesson for the present.

Early weight- and pendulum-driven clocks were inac�  curate because of friction and temperature changes and could not be used  at sea because of the ship�s motion. In 1735 John Harrison invented and  constructed the first of four practical marine timekeepers. The modern  marine chronometer is suspended to remain horizontal whatever the incli�  nation of the ship and differs in parts of its mechanism from the ordinary  watch.

One of the Five Classics of Confucianism, it  recounts events during the reign of 12 rulers of Lu from 722 bc to just  before Confucius�s death in 479 bc. The Confucian Dong Zhongshu  claimed that the natural phenomena recorded (e.g., drought, eclipse) were  intended to warn future rulers of what happens when leaders prove unwor�  thy. Since Confucian scholars were official interpreters of the classics, the  book was a means for imposing Confucian ideals. The commentary called  Zuo zhuan is significant.</p><p>church Building for Christian worship. The earliest Western churches  were based on the plan of the Roman basilica. In Constantinople, Anato�  lia, and Eastern Europe, the Orthodox church adopted the symmetrical  Greek-cross plan, which had four wings of equal size projecting from a  central, square, domed area (see Byzantine architecture). The late 11th cen�  tury saw increased complexity in cathedrals, but the innovative hall church  did not establish itself until the 14th century. The basilica and hall church  dominated Western church design until the mid-20th century. Moderniza�  tion of rituals and an innovative spirit have resulted in architectural experi�  mentation that sometimes departs completely from traditional forms.</p><p>church In Christian doctrine, the religious community as a whole, or an  organized body of believers adhering to one sect�s teachings. The word  church translates the Greek ekklesia , used in the New Testament for the  body of faithful and the local congregation. Christians established congre�</p><p>gations modeled on the synagogue and a system of governance centred on  the bishop. The Nicene Creed characterized the church as one (unified), holy  (created by the Holy Spirit), catholic (universal), and apostolic (historically  continuous with the Apostles). The schism of Eastern and Western  churches (1054) and the Reformation (16th century) ended institutional  unity and universality. St. Augustine stated that the real church is known  only to God, and Martin Luther held that the true church had members in  many Christian bodies and was independent of any organization.</p><p>Church, Alonzo (b. June 14, 1903, Washington, D.C., U.S.�d. Aug.  11, 1995, Hudson, Ohio) U.S. mathematician. He earned a Ph.D. from  Princeton University. His contributions to number theory and the theories  of algorithms and computability laid the foundations of computer science.  The rule known as Church�s theorem or Church�s thesis (proposed inde�  pendently by Alan M. Turing) states that only recursive functions can be  calculated mechanically and implies that arithmetic procedures cannot be  used to decide the consistency of statements formulated in accordance  with the laws of arithmetic. He wrote the standard textbook Introduction  to Mathematical Logic (1956) and helped found the Journal of Symbolic  Logic, which he edited until 1979.</p><p>Church, Frederic Edwin (b.

He traveled widely, seek�  ing out spectacular scenery and marvels of nature such as Niagara Falls,  volcanoes, icebergs, and the tropical forests of South America, and he  achieved fame and success at home and in Europe. His house, Olana, on  the Hudson River, is now a museum.</p><p>church and state Relationship between religious and secular author�  ity in society. In most ancient civilizations the separation of religious and  political orders was not clearly defined. With the advent of Christianity,  the idea of two separate orders emerged, based on Jesus�s command to  �Render unto Caesar what are Caesar�s, and to God the things that are  God�s� (Mark 12:17). The close association of religion and politics, how�  ever, continued even after the triumph of Christianity as emperors such  as Constantine exercised authority over both church and state. In the early  Middle Ages secular rulers claimed to rule by the grace of God, and later  in the Middle Ages popes and emperors competed for universal domin�  ion. During the Investiture Controversy the church clearly defined separate  and distinct religious and secular orders, even though it laid the founda�  tion for the so-called papal monarchy. The Reformation greatly under�  mined papal authority, and the pendulum swung toward the state, with  many monarchs claiming to rule church and state by divine right. The  concept of secular government, as evinced in the U.S. and postrevolu�  tionary France, was influenced by Enlightenment thinkers. In western  Europe today all states protect freedom of worship and maintain a dis�  tinction between civil and religious authority. The legal systems of some  modern Islamic countries are based on SHARfAH. In the U.S. the separa�  tion of church and state has been tested in the arena of public education  by controversies over issues such as school prayer, public funding of  parochial schools, and the teaching of creationism.</p><p>church mode In music, any one of eight scalar modes employed for  medieval liturgical melodies. The modal system was conceived for the  purpose of codifying plainchant (see Gregorian chant); the names of the  modes were borrowed from the system used by the ancient Greeks, though  the Greek system was inadequately understood and the connection  between the two is illusory. The modes are distinguished according to the  note used as the final (last note) and the emphasis placed on another note,  called the dominant. The Dorian mode�s final is D, the Phrygian mode�s is  E, the Lydian mode�s is F, and the Mixolydian�s is G. Each of these four  original modes had a parallel mode (Hypodorian, Hypophrygian, Hypoly-  dian, and Hypomixolydian) with a lower range. Though they principally  employ the tones A-B-C-D-E-F-G, some replace B with B-flat. In the 16th  century, further modes were identified�the Aeolian, on A, and the Ionian,  on C (corresponding to modern minor and major). The mode on B was  ignored because of B�s problematic tonal relationship within the scale.</p><p>Church of Christ See Church of Christ  Church of England See Church of England</p><p>Churchill, Randolph (Henry Spencer), Lord (b.

In the early 1880s he joined other  Conservatives in forming the Fourth Party, which advocated a �Tory  democracy� of progressive conservatism. In 1886, at age 37, he became  leader of the House of Commons and chancellor of the Exchequer, but  he resigned after his first budget was rejected. Though he had seemed  destined to be prime minister, this miscalculation effectively ended his  political career. He remained in the Commons until his death, but he lost  interest in politics and devoted much time to horse racing. Winston  Churchill was his son.</p><p>Churchill, Sir Winston (Leonard Spencer) (b. Nov. 30, 1874,  Blenheim Palace, Oxfordshire, Eng.�d. Jan. 24, 1965, London) British  statesman and author. Son of Lord Randolph Churchill and the American  Jennie Jerome, he had an unhappy childhood and was an unpromising  student. After joining the 4th Hussars in 1895, he saw service as both a  soldier and a journalist, and his dispatches from India and South Africa  attracted wide attention. Fame as a military hero helped him win election  to the House of Commons in 1900. He quickly rose to prominence and  served in several cabinet posts, including first lord of the Admiralty  (1911-15), though in World War I and during the following decade he  acquired a reputation for erratic judgment. In the years before World War  II, his warnings of the threat posed by Adolf Hitler�s Germany were repeat�  edly ignored. When war broke out, he was appointed to his old post as  head of the Admiralty. After Neville Chamberlain resigned, Churchill  headed a coalition government as prime minister (1940^15). He commit�  ted himself and the nation to an all-out war until victory was achieved,  and his great eloquence, energy, and indomitable fortitude made him an  inspiration to his countrymen, especially in the Battle of Britain. With  Franklin Roosevelt and Joseph Stalin, he shaped Allied strategy through the  Atlantic Charter and at the Cairo, Casablanca, and Tehran conferences.  Though he was the architect of victory, his government was defeated in  the 1945 elections. After the war he alerted the West to the expansionist  threat of the Soviet Union. He led the Conservative Party back into power  in 1951 and remained prime minister until 1955, when ill health forced  his resignation. For his many writings, including The Second World War  (6 vol., 1948-53) he was awarded the Nobel Prize for Literature in 1953;  his later works include his History of the English-Speaking Peoples (4  vol., 1956-58). He was knighted in 1953; he later refused the offer of a  peerage. He was made an honorary U.S. citizen in 1963. In his late years  he attained heroic status as one of the titans of the 20th century.</p><p>Churchill Fall s formerly Grand Falls Part of a series of cataracts and  rapids on the Churchill River, Newfoundland, Canada.

Periodic cicadas (species that occur in large num�  bers in chronologically and geographically isolated broods) appear in  regular cycles, including the well-known 17-year cicada (often errone�  ously called the 17-year locust) and 13 -year cicada.

Dec. 7, 43 bc, Formiae) Roman statesman, lawyer, scholar, and writer.  Born to a wealthy family, he quickly established a brilliant career in law  and plunged into politics, then rife with factionalism and conspiracy.  Cicero was elected consul in 63 bc. Of his speeches, perhaps the best  known are those he made against Catiline, whose uprising he foiled. He  vainly tried to uphold republican principles in the civil wars that destroyed  the Roman Republic. After the death of Julius Caesar, he delivered his 14  Philippic orations against Mark Antony. When the triumvirate of Antony,  Octavian (later Augustus), and Marcus Lepidus was formed, he was  executed. His extant works include 58 orations and more than 900 letters,  as well as many poems, philosophical and political treatises, and books  of rhetoric. He is remembered as the greatest Roman orator and the inno�  vator of what became known as Ciceronian rhetoric, which remained the  foremost rhetorical model for many centuries.</p><p>cichlid \'si-klod\ Any of more than 600 primarily freshwater fish species  (family Cichlidae), including many popular aquarium species. Cichlids  are found in the New World tropics, Africa and Madagascar, and southern  Asia. Most species are African, appearing in great diversity in the major  African lakes. Cichlids are deep-bodied and have a rounded tail. They usu�  ally grow no longer than about 12 in. (30 cm). Species may be omnivores,  herbivores, or carnivores. Cichlids are noted for their complex mating and  breeding behavior. Certain species (e.g., tilapia), known as mouthbreeders,  carry their eggs in the mouth until hatched.

July 10, 1099, Valencia) Castilian  military leader and national hero. His popular name, El Cid (from Span�  ish Arabic al-sid, �lord�), dates from his lifetime. Brought up at the court  of Ferdinand I, the Cid served the king�s eldest son, Sancho II, in his  campaign to gain control of Leon. On Sancho�s death he shifted to the  service of Alfonso VI, whom he had formerly opposed. His unauthorized  raid on the Moorish kingdom of Toledo (1081) prompted Alfonso to send  him into exile. He then entered the service of the Muslim rulers of Zara�  goza, becoming known as a general who was never defeated in battle.  Alfonso tried unsuccessfully to win him back during the Almoravid inva�  sion of Spain. The Cid maneuvered to gain control of the Moorish king�  dom of Valencia, finally succeeding in 1094. He was speedily elevated to  the status of national hero, and his exploits were celebrated in a heroic  biography and a famous 12th-century epic poem.</p><p>cider Expressed juice of apples. Apples are ground to a fine pulp and then  pressed. Hard (alcoholic) cider is fermented in vats for up to three months  before being filtered and aged (see fermentation). Sweet cider is unfer�  mented and either drunk fresh (as in the U.S.) or mellowed in pressurized  tanks first (particularly in Europe). Most cider in the U.S. is now pas�  teurized. Juice that is pasteurized, treated with a preservative, and often  clarified before being hermetically sealed in cans or bottles is marketed  as apple juice.</p><p>cientifico \se-en-'te-fi-ko\ Spanish "scientist" Member of a group of  officials who served in the government of Porfirio Diaz (1877-80, 1 884�  1911) in Mexico. Influenced by positivism and rejecting metaphysics, the�  ology, and idealism as inadequate to solve Mexico�s problems, they  advocated applying what they considered to be the scientific methods of  the social sciences to the problems of finance, education, and industrial�  ization. They had little influence on Diaz, but the movement took root in  other parts of Latin America in the late 19th and early 20th centuries.</p><p>cigar Cylindrical roll of tobacco for smoking, consisting of cut tobacco  filler formed in a binder leaf and with a wrapper leaf rolled spirally around  the bunch. Wrapper leaf, the most expensive leaf used in cigars, must be  strong, elastic, silky in texture, and even in colour; it must have a pleas�</p><p>ant flavour and good burning properties. Cigars are bigger than cigarettes,  and the odour and smoke they produce are stronger. Cigars were being  smoked by Maya Indians by the 10th century; they were reported back  to Spain by Christopher Columbus and other explorers and became popu�  lar there long before they spread to other European countries.</p><p>cigarette Paper-wrapped roll of finely cut tobacco for smoking. Ciga�  rette tobacco is usually milder than cigar tobacco. The Aztecs and other  New World peoples smoked tobacco in hollow reeds, in canes, or wrapped  in leaves, but it was in pipes and as cigars (cut tobacco wrapped in a  tobacco leaf) that the Europeans first smoked tobacco. Early in the 16th  century beggars in Sevilla, Spain, began picking up discarded cigar butts  and wrapping them in scraps of paper to smoke, creating the first Euro�  pean cigarettes. In the late 18th century cigarettes acquired respectabil�  ity, and in the 19th century their use spread throughout Europe. After  World War I smoking cigarettes became generally respectable for women  and consequently increased markedly. In the 1950s and �60s the health  hazards associated with smoking (including lung cancer and heart disease)  became widely known, and some countries launched campaigns against  smoking. Declines in smoking in those countries have been offset by  vastly increased numbers of smokers in developing nations.</p><p>cilantro See coriander</p><p>Cilicia \s3-Ti-sho\ Ancient district, southern Anatolia. The district was  located along the coast of the Mediterranean Sea south of the Taurus  Mountains. In ancient times it comprised the only land route from Ana�  tolia to Syria, making it a prized territory. Controlled by the Hittites  (14th�13th century bc), the Assyrians (8th century), and the Persian  Achaemenids (6th�4th century), it later came under Macedonian and  Seleucid rule. In the 1st century bc it became a Roman province (see  Roman Republic and Empire). The apostle Paul visited the district, which has  early Christian monuments. Muslim Arabs occupied it (7th-10th century  ad), at the end of which time it was reconquered by Byzantine Empire. It  was absorbed by the Ottoman Empire in 1515 and after 1921 became part  of the Republic of Turkey.</p><p>Cilician Gates See Taurus Mtns.</p><p>cilium Vsi-le-smV Short, eyelashlike filament that is numerous on tissue  cells of most animals. Capable of beating in unison, cilia perform a vari�  ety of functions, including providing the means of locomotion for some  protozoans, moving mammalian ova (eggs) through oviducts, generating  water currents to carry food and oxygen past the gills of clams, and clean�  ing debris from mammalian respiratory systems. Like a flagellum, a cil�  ium has a central core consisting of two central microtubules surrounded  by an outer ring of nine double fibres. Ciliary outgrowth is controlled by  the basal body, located just inside the cell surface at the base of the cil�  ium. Beneath the surface of some cells is a network of microtubular  bundles that may coordinate ciliary beating.</p><p>Cimabue \,che-m3-'bu-a\ orig. Benciviene di Pepo (b. before  1251�d. 1302) Florentine painter and mosaicist. He is documented as a  master painter in Rome in 1272. It is assumed that he was apprenticed to  an Italo-Byzantine painter, since he was strongly influenced by the Greek  Byzantine style. Though a number of works are attributed to him, the only  one dated is the mosaic of St. John the Evangelist (1301-02) in Pisa  Cathedral. He was the outstanding master of his generation and began the  movement toward greater realism that culminated in the Renaissance. His  style influenced Giotto and Duccio. Cimabue�s character may be reflected  in his name, which can best be translated as �bullheaded.�</p><p>Cimarosa \,che-ma-'r6-za\, Domenico (b. Dec. 17, 1749, Aversa,  Kingdom of Naples�d. Jan. 11,1801, Venice) Italian opera composer. Son  of a stonemason, he studied at the Naples Conservatory. His first opera was  produced in 1772, and by the mid-1780s he was internationally known. A  short engagement as kapellmeister at the Viennese court resulted in the  famous comic opera II matrimonio segreto (1792). In 1796 he became  organist in the royal chapel of Naples. He wrote some 75 operas, remark�  able for their apt characterizations and abundant comic life. He wrote many  choral works, including the cantata II maestro di cappella, a popular satire  on contemporary operatic rehearsal methods. Among his instrumental  works, which, like his operas, have been successfully revived, are many  sparkling harpsichord sonatas and a concerto for two flutes.</p><p>Cimarron Vsi-mo-.ron, , si-m9-,ran\ River River, southwestern U.S.  Rising in northeastern New Mexico, it flows 698 mi (1,123 km) to enter  the Arkansas River near Tulsa, Okla.

Their origins are obscure; lin�  guistically they are usually regarded as Thracian or Iranian. Driven by the  Scythians out of southern Russia and over the Caucasus, they entered Ana�  tolia toward the end of the 8th century bc. In 696-695 bc they conquered  Phrygia. They reached the summit of their power in 652 after taking Sar�  dis, capital of Lydia. Their decline soon began, and their final defeat may  be dated from 637 or 626, when they were routed by Alyattes of Lydia.</p><p>Cimon YsI-monV (b. c. 510�d. c. 451 bc, Cyprus) Athenian statesman  and general. He was the son of Miltiades. A conservative, he promoted  Sparta and opposed Pericles. After helping defeat the Persians at the Battle  of Salamis (480), he was elected strategus every year until 461. As com�  mander of the Delian League, he cleared the Persians from the eastern  Mediterranean and helped to lay the groundwork for the Athenian empire.  In 461 he was accused by Pericles of collaborating with Macedonia and  Sparta and was exiled for 10 years. He died leading a naval expedition  against Persia.</p><p>cinchona Vsiq-'ko-ns, sin-'ch6-no\ Any of about 40 species, mostly trees,  that make up the genus Cinchona in the madder family. Cinchona is native to  the Andes Mountains. Four species have been cultivated in tropical regions  for hundreds of years, mostly in Java and, since World War II, in Africa.  The bark is processed to obtain various alkaloids. The most significant are  quinine, used to treat malaria, and quinidine, used mainly for cardiac rhyth�  mic disorders. High demand for quinine among Europeans living in the  tropics led naturalists to smuggle cinchona seeds from South America to  plantations in Asia in the mid 1800s and to conduct intensive research lead�  ing to new high-yield strains and improved processing methods.</p><p>Cincinnati City (pop., 2000: 331,285), Ohio, U.S. Situated on the Ohio  River across from Kentucky, it was first settled in 1788; the area was  renamed in 1790 to honour the Society of the Cincinnati. A river port after  1811, it grew in importance with the opening of the Miami and Erie Canal  in 1832. Its manufactures include transportation equipment and building  materials, and it is a major inland coal port. A cultural centre, it has an  orchestra, opera and ballet companies, and several notable museums. It  is the seat of the University of Cincinnati (1819), the birthplace of Wil�  liam Howard Taft (now a national historical site), and the site of the Har�  riet Beecher Stowe House, where she lived briefly and frequently visited  her family during her tenure in the city (1832-50).</p><p>Cincinnati, Society of the Hereditary, military, and patriotic organi�  zation formed in 1783 by officers who had served in the American Revo�  lution. The group�s aims were to promote union, maintain war-forged  friendships, and help members in need. Membership was offered to all  officers and their eldest male descendants. George Washington was its first  president. The group took its name from the Roman citizen-soldier Cin-  cinnatus. The city of Cincinnati was named in its honour in 1790.</p><p>Cinco de Mayo \'seq-ko-da-'mI-o\ Spanish "Fifth of May" Mexi�  can holiday commemorating the Mexican victory over the French at Pue�  bla in 1862. The French army, better-equipped and far larger than the  Mexican army, had been sent by Napoleon III to conquer Mexico. The  Mexicans, under Gen. Ignacio Zaragoza, defeated the French at Puebla,  inflicting serious losses. The French withdrew to the coast but returned  the next year to take Puebla; they would control most of Mexico for the  next four years. Cinco de Mayo celebrations often include music, danc�  ing, and parades.</p><p>cinder cone or ash cone Deposit around a volcanic vent, formed by  rock fragments or cinders that accumulate and gradually build a conical  hill with a bowl-shaped crater at the top. Cinder cones develop from  explosive eruptions of lavas and are often found along the flanks of shield  (gently sloping) volcanoes. Lava flows may break out of the cone, or they  may flow from under the cone through tunnels. Cinder cones are common  in nearly all volcanic areas. Although they are composed of loose or only  moderately consolidated cinder, many are surprisingly long-lasting,  because rain falling on them sinks into the highly permeable cinders  instead of running off down their slopes and eroding them.</p><p>cinema verite Vsi-no-mo-.ver-i-'taV French : "truth cinema"  French film movement of the 1960s that strove for candid realism by</p><p>showing people in everyday situations with authentic dialogue. Influenced  by documentary filmmaking and Italian Neorealism, the method produced  such outstanding examples as Jean Rouch�s Chronicle of a Summer ( 1961)  and Chris Marker�s Joli Mai (1962). A similar movement in the U.S.,  where it was called �direct cinema,� captured the reality of a person or  an event by using a handheld camera to record action without narration,  as in Frederick Wiseman�s Titicut Follies (1967) and the Maysles broth�  ers� Salesman (1969).</p><p>cinematography Art and technology of motion-picture photography.  It involves the composition of a scene, lighting of the set and actors,  choice of cameras, camera angle, and integration of special effects to  achieve the photographic images desired by the director. Cinematography  focuses on relations between the individual shots and groups of shots that  make up a scene to produce a film�s effect. Well-known cinematographers  include Nestor Almendros, Gregg Toland, and Sven Nykvist.</p><p>cinnabar Mercury sulfide (HgS), the chief ore mineral of mercury. It is  commonly encountered with pyrite,  marcasite, and stibnite in veins near  recent volcanic rocks and in hot-  springs deposits. It has been used as  a bright orange-red pigment in stage  makeup (now known to be toxic),  painting, and Chinese lacquerwork.</p><p>cinnamon Bushy evergreen tree  {Cinnamomum zeylanicum) of the  laurel family. Native to Sri Lanka,</p><p>India, and Burma, cinnamon is also  cultivated in South America and the  West Indies for the spice consisting  of its dried inner bark. The light-  brown spice has a delicately fragrant  aroma and warm, sweet flavor. It was once more valuable than gold. Today  cinnamon is used to flavor various foods. In Europe and the U.S. it is  especially popular in bakery goods. The oil is distilled from bark frag�  ments for use in food, liqueur, perfume, and drugs.</p><p>Cinque Ports VsiqkV Medieval confederation of English Channel ports,  southeastern England. To the original �five ports��Hastings, New Rom�  ney, Hythe, Dover, and Sandwich�were later added Winchelsea and Rye.  Probably first associated in the reign of Edward the Confessor (r. 1042-  66) to defend the coast and cross-channel traffic, they were granted spe�  cial privileges by the crown and in exchange provided the permanent  nucleus of ships and men for the royal fleet. They declined in importance  after the 14th century.</p><p>cinquefoil \'siqk-foil\ Any of the approximately 500 species of shrubs  and herbaceous plants in the genus  Potentilla (rose family). The com�  mon name, meaning �five-leaved,�  refers to the number of leaflets in the  compound leaf of most species. Most  species are native to the northern  temperate zone and the Arctic and  are chiefly perennial. The stems are  creeping or erect. The solitary, five-  petaled flowers are usually yellow,  sometimes white or red in horticul�  tural varieties. P. fruticosa includes  many dwarf shrubs used in landscap�  ing (see LANDSCAPE GARDENING).</p><p>Ciompi Ycham-peV, Revolt of the (1378) Uprising of cloth workers  and other craftsmen in Florence that brought a democratic government to  power. A struggle between ruling factions triggered the rebellion, which  was led by the ciompi (wool carders). The rebels demanded a more equi�  table fiscal policy and the right to establish guilds for those groups not  already organized. They took over the government briefly, but worsening  economic conditions and the combined efforts of the established guilds  soon led to their ouster.</p><p>circadian rhythm \s3r-'ka-de-3n\ Inherent cycle of approximately 24  hours in length that appears to control or initiate various biological pro�  cesses, including sleep, wakefulness, and digestive and hormonal activ�  ity.

Until the 1860s  Circassian-speaking groups inhabited the entire northwestern Caucasus  region, including the Black Sea coast. After the Russian conquest of the  northwestern Caucasus in 1864, most Circassian-speakers immigrated to  the Ottoman Empire and were eventually settled in present-day Turkey,  Syria, Jordan, and Israel. Only scattered enclaves of Western Circassian-  speakers stayed in Russia. A greater number of Eastern Circassians  remained; most now live in Russia�s northern Caucasus republics. Rus�  sian Circassian-speakers now number about 550,000; the number outside  Russia is indeterminable, because many ethnic Circassians have switched  to the dominant languages of their new countries.</p><p>Circe \'sor-se\ In Greek legend, a sorceress, the daughter of the sun god  Helios and the ocean nymph Perse. By means of drugs and incantations  she turned humans into lions, wolves, or swine. Odysseus visited her on  his return from the Trojan War, and she changed his companions into  swine. Odysseus himself was protected by an herb given him by Hermes,  and he compelled the sorceress to restore his companions. He and Circe  became lovers, but after a yearlong stay he resumed his journey home�  ward.</p><p>Circeo \chir-'cha-o\, Mt. ancient Circaeum Promontorium.</p><p>Mountain, southwestern coast of Italy. The promontory, on the Tyrrhenian  Sea, rises 1,775 ft (541 m), and is connected with the mainland by a low  saddle. About 33 sq mi (86 sq km) are preserved as a national park. From  the sea it resembles an island, and it has been associated with the legend  of Circe since classical times. Its coastal grottoes have yielded traces of  Stone Age settlement, and there are remains of a Roman acropolis.</p><p>circle Geometrical curve, one of the conic sections, consisting of the set  of all points the same distance (the radius) from a given point (the cen�  tre). A line connecting any two points on a circle is called a chord, and a  chord passing through the centre is called a diameter. The distance around  a circle (the circumference) equals the length of a diameter multiplied by  k (see pi). The area of a circle is the square of the radius multiplied by n.  An arc consists of any part of a circle encompassed by an angle with its  vertex at the centre (central angle). Its length is in the same proportion to  the circumference as the central angle is to a full revolution.</p><p>circuit or electric circuit Path that transmits electric current. A circuit  includes a battery or a generator that gives energy to the charged par�  ticles; devices that use current, such as lamps, motors, or electronic com�  puters; and connecting wires or transmission lines. Circuits can be  classified according to the type of current they carry (see alternating cur�  rent, direct current) or according to whether the current remains whole  (series) or divides to flow through several branches simultaneously (par�  allel). Two basic laws that describe the performance of electric circuits  are Ohm's law and Kirchhoff's circuit rules.

In humans, blood remains  within a closed cardiovascular system composed of the heart, blood ves�  sels, and blood. Arteries carry blood away from the heart under high pres�  sure exerted by the heart�s pumping action. Arteries divide into smaller  arterioles, which branch into a network of tiny capillaries with thin walls  across which gases and nutrients diffuse. Capillaries rejoin into larger  venules, which unite to form veins, which carry blood back to the heart.  (See artery; capillary; vein.) The right and left heart chambers send blood  into separate pulmonary and systemic circulations. In the first, blood is  carried from the heart to the lungs, where it picks up oxygen and releases  carbon dioxide; in the second, blood is carried between the heart and the  rest of the body, where it carries oxygen, nutrients, metabolic products,  and wastes. See illustration above.</p><p>right common</p><p>internal jugular  vein</p><p>right pulmonary  artery</p><p>right subclavian  artery</p><p>right subclavian  vein</p><p>superior  vena cava  right  veins</p><p>ventricle  right  inferior  vena</p><p>vessels  liver</p><p>renal blood  vessels</p><p>superior  mesenteric artery</p><p>ascending colon</p><p>common iliac</p><p>external iliac vein</p><p>brachiocephalic  (innominate) artery</p><p>left common carotid artery  left subclavian artery  -aorta</p><p>left pulmonary  artery</p><p>pulmonary  veins</p><p>left atrium</p><p>ventricle</p><p>aorta</p><p>gastric  arteries</p><p>spleen</p><p>splenic  artery</p><p>stomach</p><p>-inferior</p><p>mesenteric artery</p><p>descending</p><p>colon</p><p>external iliac artery</p><p>Human circulatory system. Oxygen-rich blood is shown in red, oxygen-poor blood  in blue. The pulmonary circulation consists of the right ventricle and the exiting pul�  monary artery and its branches, the arterioles, capillaries, and venules of the lung,  and the pulmonary vein. Unlike the other arteries and veins, the pulmonary arteries  carry deoxygenated blood and the pulmonary veins carry oxygenated blood. The  aorta arises from the left ventricle. The brachiocephalic artery arises from the aorta  and divides into the right common carotid and right subclavian arteries. The left  and right common carotids extend on either side of the neck and supply much of  the head and neck. The left subclavian artery (arising from the aorta) and the right  subclavian artery supply the arms. In the lower abdomen, the aorta divides into the  common iliac arteries, which give rise to external and internal branches supplying  the legs.</p><p>� MERRIAM-WEBSTER INC.</p><p>circumcision Cutting away of all or part of the foreskin (prepuce) of  the penis. The practice is known in many cultures. It is performed either  shortly after birth (e.g., among Muslims and Jews), within a few years of  birth, or at puberty. For Jews it represents the fulfillment of the covenant  between God and Abraham (Genesis 17:10-14). That Christians were not  obliged to be circumcised was first recorded biblically in Acts 15. Evi�  dence regarding the purported medical benefits of circumcision (e.g.,  reduced risk of cancer) is inconclusive, and the practice persists mainly  for cultural reasons. See also clitoridectomy.</p><p>circumstantial evidence In law, evidence that is drawn not from  direct observation of a fact at issue but from events or circumstances that  surround it. If a witness arrives at a crime scene seconds after hearing a  gunshot to find someone standing over a corpse and holding a smoking  pistol, the evidence is circumstantial, since the person may merely be a  bystander who picked up the weapon after the killer dropped it. The  popular notion that one cannot be convicted on circumstantial evidence  is false. Most criminal convictions are based, at least in part, on circum�  stantial evidence that sufficiently links criminal and crime.</p><p>circus Entertainment or spectacle featuring animal acts and human feats  of daring. The modem circus was founded in England in 1768 by the  bareback rider Philip Astley (1742-1814), who built stands around his  performance ring and opened Astley�s Amphitheatre.

Horse acts were later  joined by wild-animal acts. After the invention of the flying trapeze by  Jules Leotard (1859), aerial acts were featured. P.T. Barnum expanded the  traditional circus by adding two rings to create the three-ring circus (1881)  and augmented it with sideshow performers. Circuses traveled through�  out the U.S., Europe, and Latin America, performing in a tent (the Big  Top) into the 1950s. Today circuses usually perform in permanent build�  ings, though small troupes still travel with tents in some regions. By the  late 20th century, notable circuses also had developed in Africa, India,  Spain, Brazil, and Mexico. Perhaps the most innovative trend in circuses  at the turn of the 21st century was the establishment of companies such  as the Cirque du Soleil; these companies employed no animals, instead  emphasizing acts of human skill and daring and integrating elements of  contemporary music and dance into the overall performance.</p><p>Cirenaica See Cyrenaica</p><p>cirrhosis \s9-'ro-s9s\ Degeneration of functioning liver cells and their  replacement with fibrous connective tissue, leading to scarring.

Inhabited princi�  pally by Xhosa-speaking peoples, it bordered the Indian Ocean and South  Africa. In the late 18th century the Xhosa peoples living in the area came  into conflict with European settlers; the ensuing wars resulted in the  region�s incorporation into the Cape Colony by the end of the 19th cen�  tury. Ciskei became an administratively distinct territory within South  Africa in 1961. In 1972 it was declared a self-governing black state, with  its capital at Bisho. In 1981 it became nominally independent. Under the  new South African constitution, it was reincorporated (1994) into South  Africa as part of the new Eastern Cape province.</p><p>Cistercian \sis-'t3r-sh3n\ or White Monk or Bernardine Member  of a Roman Catholic monastic order founded by St. Stephen Harding  (1098) at Citeaux (Latin, Cistercium), Burgundy, by Benedictines dissatis�  fied with their abbey�s laxity. Cistercians were severely ascetic, rejected  feudal revenues, and engaged in manual labor. Uniform rules applied to  all houses, and all abbots were to meet annually at Citeaux. St. Bernard  de Clairvaux founded 68 abbeys in his lifetime. Discipline declined as the  order grew, and Cistercians disappeared from northern Europe after the  Reformation. The order underwent reforms in the 16th-17th century;  members of the reformed order are popularly known as Trappists after the  abbey of La Trapp. Until the 1960s, they slept, ate, and worked in per�  petual silence. The original order, which underwent more moderate  reforms, also survives.</p><p>Citation (foaled 1945) U.S. Thoroughbred racehorse.

In general, full political rights, including the right to vote and to  hold public office, are predicated on citizenship. Citizenship entails obli�  gations, usually including allegiance, payment of taxes, and military ser�  vice. The concept arose in ancient Greece, where citizenship was granted  only to property owners. The Romans initially used it as a privilege to be  conferred upon or withheld from conquered peoples, but it was granted  to all the empire�s free inhabitants in ad 212. The concept disappeared in  Europe during the feudal era but was revived in the Renaissance. Citi�  zenship may normally be gained by birth within a certain territory, descent  from a parent who is a citizen, marriage to a citizen, or naturalization.

It is present in almost all plants (especially citrus fruits)  and in many animal tissues and fluids. It is one of a series of compounds  involved in the physiological oxidation (see oxidation-reduction) of fats,  proteins, and carbohydrates to carbon dioxide and water (see tricarboxylic  acid cycle). It has a characteristic sharply sour taste and is used in many  foods, confections, and soft drinks. It is added to certain foods to improve  their stability in metal containers. Industrially, it is used as a water condi�  tioner, cleaning and polishing agent, and chemical intermediate.</p><p>citric-acid cycle See tricarboxylic acid cycle</p><p>citrine \si-'tren\ Transparent, coarse-grained variety of the silica mineral  quartz. Citrine is a semiprecious gem that is valued for its yellow to  brownish colour and its resemblance to the rarer topaz. Natural citrine is  rarer than amethyst or smoky quartz, both of which are often heated to  change their natural colour to that of citrine. Citrine is often marketed  under various names that confuse it with topaz to inflate its price; it may  be distinguished from topaz by its inferior hardness. It occurs mainly in  Brazil, Uruguay, the Ural Mountains, Scotland, and North Carolina.</p><p>Citroen \si-tro-'en\ Historic French automobile manufacturer. It was  founded by Andre-Gustave Citroen (1878-1935), an engineer and indus�  trialist who initially prospered by selling munitions in World War I. He  converted his arms factory to produce small, inexpensive automobiles,  introducing mass-production methods to the French auto industry. The  first Citroen car appeared in 1919. The 1976 acquisition of Citroen by  rival French automaker Peugeot led to the creation of PSA Peugeot Cit�  roen SA, which was a leading European manufacturer of trucks and auto�  mobiles.</p><p>citron Small evergreen tree or shrub (Citrus medico). A member of the  rue family, citron is cultivated in Mediterranean countries and the West  Indies. It has irregular, spreading, spiny branches and large, pale green,  broadly oblong leaves. The flowers of the acidic varieties (e.g., the Dia�  mante) are purple on the outside and white on the inside; those of sweet  varieties (e.g., the Corsican) are creamy white. The oval or oblong fruit  yields firm pulp, either acidic or sweet, that is used only for by-products.  The thick peel is cured in brine, candied, and sold as a confection. The  fruit of the Etrog variety is used in Jewish religious rites.</p><p>citrus Any of the plants that make up the genus Citrus, in the rue family,  that yield pulpy fruits covered with fairly thick skins. The genus includes  the lemon, lime, sweet and sour oranges, tangerine, grapefruit, citron, and  shaddock (C. maxima, or C. grandis', also called pomelo).</p><p>citrus family See rue family</p><p>city Relatively permanent and highly organized centre of population, of  greater size or importance than a town or village. The first cities appeared  in Neolithic times when the development of agricultural techniques  assured surplus crop yields large enough to sustain a permanent popula�  tion. Ancient Greece saw the creation of the city-state, a form also impor�  tant in the emergence of the Roman empire as well as the medieval Italian  trading centers of Venice, Genoa, and Florence. After the Middle Ages,  cities came increasingly under the political control of centralized govem-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>410 I city government &#x25BA; civil law</p><p>ment and served the interests of the nation-state. The Industrial Revolution  further transformed city life, as factory cities blossomed rapidly in  England, northwestern Europe, and the northeastern U.S. By the mid-20th  century, 30-60% of a country�s population might be living in its major  urban centers. With the rise of the automobile came the growth of sub�  urbs and urban sprawl, as factories, offices, and residences erected in ear�  lier periods became aged and obsolete. Today many cities suffer from lack  of adequate housing, sanitation, recreational space, and transportation  facilities, and face problems of inner-city decay or burgeoning shanty�  towns. Local governments have sought to alleviate these problems  through URBAN PLANNING.</p><p>city government Set of governmental institutions that serve an urban  area or urban municipality. All cities derive their existence from a larger  political entity, either a state or national government. City government  generally includes an executive (a mayor or manager) and a legislature (a  council or commission), both of which may be subject to popular elec�  tion. Their most important functions are the provision of services, includ�  ing public safety, health care, education, recreation, housing, utilities,  transportation, and cultural facilities. Revenues come from local taxes and  fees as well as grants and subsidies from its state or national government.</p><p>city-state Political system consisting of an independent city with sov�  ereignty over a fixed surrounding area for which it served as leader of reli�  gious, political, economic, and cultural life. The term was coined in the  19th century to describe ancient Greek and Phoenician settlements that  differed from tribal or national systems in size, exclusivity, patriotism,  and ability to resist incorporation by other communities. They may have  developed when earlier tribal systems broke down and splintered groups  established themselves as independent nuclei c. 1000-800 bc; by the 5th  century bc they numbered in the hundreds, with Athens, Sparta, and Thebes  among the most important. Incapable of forming any lasting union or fed�  eration, they eventually fell victim to the Macedonians, the Carthagin�  ians, and the Roman empire. In the 11th century the city-state revived in  Italy; the success of medieval Italy�s city-states, including Pisa, Florence,  Venice, and Genoa, was due to growing prosperity from trade with the  East, and several survived into the 19th century. Germany�s medieval  city-states included Hamburg, Bremen, and Lubeck. The only city-state  extant today is Vatican City.</p><p>Ciudad Guayana V.syii-'thath-ga-'ya-na \ formerly Santo Tome de  Guayana City (pop., 2000 est.: 704,168), Venezuela. Located at the  confluence of the Carom and Orinoco rivers in the Guiana Highlands, the  city site was first settled in 1576. An amalgamation of several cities,  Ciudad Guayana is a planned community founded by the state assembly  in 1961. It has forestry, diamond mining, and paper and pulp enterprises.</p><p>Ciudad Juarez See Juarez</p><p>Ciudad Victoria \ l syii-'thath-vek- , t6r-ya\ City (pop., 2000: 249,029),  capital of Tamaulipas state, northeastern Mexico. Founded in 1750, the  settlement was renamed in 1825 for Mexico�s first president, Guadalupe  Victoria. In addition to being a distribution point in an agricultural region,  it is a tourist destination and a centre for hunting, fishing, and swimming.  The University of Tamaulipas was established in 1956.</p><p>civet Vsi-v3t\ Any of 15-20 species of long-bodied, short-legged carni�  vores (family Viverridae) found in  Africa, southern Europe, and Asia.</p><p>Catlike in appearance, civets have a  thickly furred tail, small ears, and  pointed snout. Civets are commonly  buff or grayish, with black spots or  stripes or both. They range in length  from 16 to 34 in. (40-85 cm),  excluding the 5-26-in. (13-66-cm)  tail, and in weight from 3.3 to 24 lbs  (1.5�11 kg). Civets mark territories  with a greasy, musklike secretion  (called civet) stored in a pouch under  the tail; civet is sometimes used in  the manufacture of perfumes. Usu�  ally solitary, civets feed on small animals and on vegetable matter. Five  species are considered in possible danger of extinction.</p><p>civic center Grouping of municipal facilities in a limited precinct often  adjacent to the central business district of a city. The civic center is based</p><p>on both the Greek acropolis and the Roman forum. The plan includes the  city hall and adjoining park or plaza, headquarters for city departments,  courthouses, and often a post office, public-utility offices, public health  facilities, and government offices.</p><p>civic theatre Theatre wholly or partly subsidized by the city in which  it operates. The term is also used for a noncommercial community the�  atre, meaning a noncommercial, locally based group. Most civic theatres  in Europe are professional organizations; in the U.S. they are often run  by amateur groups and may later become resident professional theatres.  The first major U.S. civic theatre was established in New Orleans in 1919.</p><p>Civil Constitution of the Clergy (July 12, 1790) Act, passed by the  National Assembly during the French Revolution, that subordinated the  Roman Catholic church in France to the state. Under its provisions,  enfranchised citizens would elect bishops and parish priests and the state  would pay the clergy�s wages. The act soon provoked opposition, and  when the National Assembly ordered the clergy to take an oath support�  ing the Civil Constitution, many refused. The resulting schism within the  French church caused many devout Catholics to turn against the Revo�  lution.</p><p>civil defense All nonmilitary actions taken to reduce loss of life and  property resulting from enemy action. The threat of aerial attack on cit�  ies led to organized civil-defense planning in World War II. The British  government provided its people with gas masks, and nearly all countries  trained citizens in fire fighting, rescue, and first aid. Blackouts reduced  the glow from city lights that could guide enemy pilots; sirens warned of  bombing attacks, and citizens took cover in air-raid shelters, basements,  and subways. The postwar threat of nuclear attack prompted civil authori�  ties to mark buildings that offered the best shelter from fallout. By the  1970s the West had largely abandoned civil-defense preparations as it  became clear that surviving a direct nuclear attack was unlikely.</p><p>civil disobedience or passive resistance Refusal to obey gov�  ernment demands or commands and nonresistance to consequent arrest  and punishment. It is used especially as a nonviolent and usually collec�  tive means of forcing government concessions and has been a major tac�  tic of nationalist movements in Africa and India, of the U.S. civil rights  movement, and of labour and antiwar movements in many countries. Civil  disobedience is a symbolic or ritualistic violation of the law, rather than  a rejection of the system as a whole. The civil disobedient, finding legiti�  mate avenues of change blocked or nonexistent, sees himself as obligated  by a higher, extralegal principle to break some specific law. By submit�  ting to punishment, the civil disobedient hopes to set a moral example  that will provoke the majority or the government into effecting meaning�  ful political, social, or economic change. The philosophical roots of civil  disobedience lie deep in Western thought. Cicero, Thomas Aquinas, and  John Locke, among others, appealed to systems of natural law that take  precedence over the laws created by communities or states (positive law).  More modern advocates and practitioners of civil disobedience include  Henry David Thoreau, Mohandas K. Gandhi, and Martin Luther King, Jr.</p><p>civil engineering Profession of designing and executing structural  works that serve the general public, including bridges, canals, dams, har�  bors, lighthouses, roads, tunnels, and environmental works (e.g., water-  supply systems). The modern field includes power plants, aircraft and  airports, chemical-processing plants, and water-treatment facilities. Civil  engineering today involves site investigations and feasibility studies,  structural design and analysis, construction, and facilities maintenance.  The design of engineering works requires the application of design theory  from many fields (e.g., hydraulics, thermodynamics, nuclear physics).  Research in structural analysis and the technology of materials such as  steel and concrete has opened the way for new concepts and greater  economy of materials. The engineer�s analysis of a building problem  determines the structural system to be used. Structural designs are rigor�  ously analyzed by computers to determine if they will withstand loads  and natural forces.</p><p>civil law Body of law developed from Roman law and used in conti�  nental Europe and most former colonies of European nations, including  the province of Quebec and the U.S. state of Louisiana. The most sig�  nificant codifications of modern civil law were the French (Napoleonic  Code) and the German (German Civil Code). The basis of law in civil-law  jurisdictions is statute, not CUSTOM; civil law is thus to be distinguished  from common law. In civil law, judges apply principles embodied in stat�  utes, or law codes, rather than turning to case precedent. French civil law</p><p>African palm civet (Nandinia binotata)</p><p>ROBERT C.

German civil law prevails in Austria,  Switzerland, the Scandinavian countries, and certain countries outside  Europe, such as Japan, that have westernized their legal systems. The term  is also used to distinguish the law that applies to private rights from the  law that applies to criminal matters. See also criminal law; tort.</p><p>civil liberty Freedom from arbitrary interference in one�s pursuits by  individuals or by government. The term is usually used in the plural. Civil  liberties are protected explicitly in the constitutions of most democratic  countries. (In authoritarian countries, civil liberties are often formally  guaranteed in a constitution but ignored in practice.) In the U.S., civil  liberties are guaranteed by the Bill of Rights and the 13th, 14th, and 15th  Amendments to the Constitution of the United States. The Constitution�s  13th Amendment prohibits slavery and involuntary servitude; the 14th  bars the application of any law that would abridge the �privileges and  immunities� of U.S. citizens or deprive any person of �life, liberty, or  property...without due process of law� or deny any person equal protec�  tion under the law; and the 15th guarantees the right of all U.S. citizens  to vote. The related term civil right is often used to refer to one or more  of these liberties or indirectly to the obligation of government to protect  certain classes of people from violations of one or more of their civil lib�  erties (e.g., the obligation to protect racial minorities from discrimination  on the basis of race). In the U.S., civil rights are protected by the Civil  Rights Act of 1964 and subsequent legislation. See also American Civil  Liberties Union.</p><p>civil religion Set of quasi-religious attitudes, beliefs, rituals, and sym�  bols that tie members of a political community together. As originally for�  mulated by Jean-Jacques Rousseau, the concept referred to the virtues that  citizens need to serve the state. The concept was later elaborated by the  American sociologist Robert N. Bellah (b. 1927), who found in the U.S.  a strong sense of �American exceptionalism� and reverence for secular  elements such as the national flag, the Constitution, the Founding Fathers,  the annual holiday calendar, and the concepts of individualism and self-  reliance. Another form of civil religion is presented by the example of  Confucianism, where the nation is subordinated to a moral order.</p><p>Civil Rights Act of T 964 Comprehensive U.S. law intended to end  discrimination based on race, colour, religion, or national origin. It is gen�  erally considered the most important U.S. law on civil rights since Recon�  struction (1865-77). It guarantees equal voting rights (Title I); prohibits  segregation or discrimination in places of public accommodation (Title  II); bans discrimination, including sex-based discrimination, by trade  unions, schools, or employers that are involved in interstate commerce or  that do business with the federal government (Title VII); calls for the  desegregation of public schools (Title IV); and assures nondiscrimination  in the distribution of funds under federally assisted programs (Title VI). A  1972 amendment, the Equal Employment Opportunity Act, extended Title  VII coverage to employees of state and local governments and increased  the authority of the Equal Employment Opportunity Commission, which  was created in 1964 to enforce Title VII provisions. The act was proposed  by Pres. John F. Kennedy in 1963 and strengthened and passed into law  under Pres. Lyndon B. Johnson. See also civil rights movement.</p><p>civil rights movement Movement for racial equality in the U.S. that,  through nonviolent protest, broke the pattern of racial segregation in the  South and achieved equal rights legislation for blacks. Following the U.S.  Supreme Court decision in Brown v. Board of Education of Topeka (1954),  African American and white supporters attempted to end entrenched seg�  regationist practices. When Rosa Parks was arrested in 1955 in Montgom�  ery, Ala., an African American boycott of the bus system was led by  Martin Luther King, Jr., and Ralph Abernathy. In the early 1960s the Stu�  dent Nonviolent Coordinating Committee led boycotts and sit-ins to  desegregate many public facilities. Using the nonviolent methods of  Mohandas K. Gandhi, the movement spread, forcing the desegregation of  department stores, supermarkets, libraries, and movie theatres. The Deep  South remained adamant in its opposition to most desegregation mea�  sures, often violently; protesters were attacked and occasionally killed.  Their efforts culminated in a march on Washington, D.C., in 1963 to sup�  port civil rights legislation. Following the assassination of John F. Kennedy,  Pres. Lyndon B. Johnson persuaded Congress to pass the Civil Rights Act  of 1964, a victory that was followed by the Voting Rights Act in 1965.  After 1965, militant groups such as the Black Panther Party split off from  the civil rights movement, and riots in black ghettos and King�s assassi�</p><p>nation caused many supporters to withdraw. In the succeeding decades,  leaders sought power through elective office and substantive economic  and educational gains through affirmative action.</p><p>civil service Body of government officials employed in civil occupa�  tions that are neither political nor judicial. In well-ordered societies, they  are usually recruited and promoted on the basis of a merit-and-seniority  system, which may include examinations; elsewhere, corruption and  patronage are more important factors. They often serve as neutral advis�  ers to elected officials and political appointees. Though not responsible  for making policy, they are charged with its execution. The civil service  originated in the earliest known Middle Eastern societies; the modern  European civil services date to 17th- and 18th-century Prussia and the  electors of Brandenburg. In the U.S., senior officials change with each  new administration. In Europe, regulations were established in the 19th  century to minimize favouritism and to ensure a wide range of knowledge  and skills among civil service officers.

Recruits  lived in semimilitary work camps and received $30 a month as well as  food and medical care. Projects included planting trees, building flood  barriers, fighting forest fires, and maintaining forest roads and trails.

Nov. 15, 1908, Beijing) Imperial con�  sort who controlled the Chinese Qing dynasty for almost half a century.  A low-ranking concubine of the Xianfeng emperor (r. 1850-61), Cixi bore  his only son, the future Tongzhi emperor, in 1856. After the emperor�s  death, Cixi joined a triumviral regency that governed in the name of her  son, who was only 6 at his accession. During that period the Taiping and  Nian rebellions were put down and the government was briefly revital�  ized. When Cixi�s son died in 1875, Cixi violated the laws of succession  and had her adoptive nephew enthroned. The regency thus continued, with  Cixi becoming sole regent in 1884. In 1889 she nominally relinquished  control but returned in 1898 to undo a set of radical reforms and had her  nephew imprisoned in his palace. She supported the unsuccessful Boxer  Rebellion, which had disastrous consequences for China. In 1902 she began  to implement the reforms she had earlier reversed. Before she died, she  ordered her nephew poisoned. See also Zeng Guofan; Zhang Zhidong.</p><p>Cixous \sek-'zus\, Helene (b. June 5, 1937, Oran, Alg.)

Emigrating  to Virginia in 1621, he was appointed secretary of state of the colony and  a member of the governor�s royal council. He traded with the Indians of  Chesapeake Bay and in 1631 established a successful trading post on Kent  Island. Denied his claim to the island, he incited a revolt (1644) that ousted  the Maryland governor and left Claiborne in charge of the colony until  1646.

Clans are normally exogamous, marriage within the clan being  regarded as incest. Clans may segment into subclans or lineages, and  genealogical records and myths may be altered to incorporate new mem�  bers who lack kinship ties with the clan. Clan membership may be useful  in ensuring mutual support and defense as well as in the mediation of  disputes over property rights and the mode of residence after marriage.  Some clans express their unity by means of a common emblem. See also  EXOGAMY AND ENDOGAMY.</p><p>Clancy, Tom orig. Thomas Clancy (b. March 12, 1947, Baltimore,  Md., U.S.) U.S. novelist. Clancy worked as an insurance agent before  beginning his writing career. His first novel was the surprise best-seller  The Hunt for Red October (1984; film, 1990), which virtually created the  �technothriller� genre, suspenseful novels that rely on extensive knowl�  edge of military technology and espionage. Later successes include Red  Storm Rising (1986), Patriot Games (1987; film, 1992), Clear and Present  Danger (1989; film, 1994), Sum of All Fears (1991; film, 2000), and The  Bear and the Dragon (2000).</p><p>clapboard Vkla-bardX Narrow board tapered toward one edge, used as  siding to cover the exterior of a framed building.

The claque dates from  ancient times. Comedy competitions in Athens were often won by con�  testants who infiltrated audiences with paid supporters. The practice was  widespread in Rome, where the emperor Nero established a school of  applause. In 19th-century France most theatres had specialized claques:  rieurs laughed loudly at comedies, pleureuses wept at melodramas, and  bisseurs shouted for encores. The practice persists today in the operatic  world.</p><p>Clare County (pop., 1996: 94,006), western Ireland.

Evidence of prehis�  toric settlement includes many megaliths and some 2,000 fortified  enclosures. There are numerous early Christian sites. The region remained  under the lordship of the O�Briens until the 16th century despite Anglo-  Norman colonization in the 12th century. It was made a shire in the reign  of Elizabeth I. In 1828 Daniel O'Connell won the election in Clare that led  to the emancipation of Catholics in Ireland.</p><p>Clare, John (b.

Clare grew up in extreme rural poverty, with little access to books,  but he had a prodigious memory and absorbed folk ballads. His Poems  Descriptive of Rural Life and Scenery (1820) brought a short period of  celebrity, but later volumes, including The Shepherd�s Calendar (1827)  and The Rural Muse (1835), sold poorly. Suffering from penury and poor  health, he fell prey to delusions and was placed in an asylum in 1837. After  four years he briefly escaped; certified insane, he spent his final 23 years in  another asylum, where he wrote some of his most lucid, lyrical poetry.</p><p>Clare of Assisi, Saint (b.

Born to a noble family, she became  devoted to her fellow Assisian St. Francis. She refused to marry and in  1212 fled to the Porziuncola Chapel, where St. Francis received her vows.  She later became abbess of a female religious community that included  her sister, St. Agnes, and her mother. Her order, the Second Order of St.  Francis, or Poor Clares, adopted the absolute poverty of St. Francis but  was strictly cloistered, unlike its counterpart, the Franciscans. Still allied  with the Franciscans, the Poor Clares are noted for their poverty and their  life of penitential prayer led for the good of church and society.</p><p>Claremont Colleges Consortium of private colleges in Claremont,  California, U.S. It comprises Pomona College (founded 1887), the Cla�  remont Graduate School (1925), Scripps College (1926), Claremont Mc�  Kenna College (1946), Harvey Mudd College (1955), and Pitzer College  (1963).

Designed to restrict  ecclesiastical privileges and curb the power of the church courts, the con�  stitutions provoked the famous quarrel between Henry and St. Thomas  Becket. Among their controversial measures were the provisions that all  revenues from vacant sees and monasteries reverted to the king, who had  discretion in filling the vacant offices, and that clerics charged with seri�  ous crimes were to be tried in secular courts. Becket�s martyrdom in 1170  forced Henry to moderate his attack on the clergy, but he did not repu�  diate the constitutions.</p><p>Clarendon, Edward Hyde, 1 st earl of (b.

As a member of Parliament, he became an adviser to Charles I, recom�  mending moderate policies, but was unable to prevent the English Civil  Wars. He helped bring about the Restoration of Charles II and was created  earl of Clarendon in 1661. As lord chancellor (1660-67), he dominated  most aspects of the administration. His criticism of the king�s immorality  eventually destroyed their friendship, and Parliament made him a scape�  goat for the disasters of the Anglo-Dutch War of 1665. Dismissed as lord  chancellor in 1667, he spent the rest of his life in exile in France, where he  completed his History of the Rebellion and Civil Wars in England.</p><p>Clarendon, George William Frederick Villiers, 4th earl of</p><p>(b.

It is a standard member of  both orchestras and bands. It has a cylindrical bore and a flared bell, and  it is usually made of African blackwood ( Dalbergia melanoxylon, more  commonly called renadilla). It has a 3V6-octave range; its lower register  is rich and its top register is brilliant. It developed from the slightly older  two-key chalumeau; the German flute maker Johann Christoff Denner  (1655-1707) is said to have invented it at the beginning of the 18th cen�  tury. The B-flat clarinet is the standard instrument today; the A clarinet  often replaces it in sharp keys. Clarinets with the fingering system devised  by Theobald Boehm are standard in the U.S., Great Britain, and France;  those employing an older fingering style are used in Germany and Rus�  sia. Clarinets of other sizes include the C clarinet, much used in the Clas�  sical period and often preserved in German orchestration; octave clarinets  in A, used in large European bands; and sopranino clarinets in F and later  E-flat. The B-flat bass clarinet, with its rich timbre, is the next most fre�  quently employed member of the clarinet family. Contrabass clarinets are  made in E-flat or in B-flat.</p><p>Clark, Champ orig.

The term was first widely used in the early 19th  century, following the industrial and political revolutions of the late 18th  century. The most influential early theory of class was that of Karl Marx,  who focused on how one class controls and directs the process of pro�  duction while other classes are the direct producers and the providers of  services to the dominant class. The relations between the classes were</p><p>Helen Clark, 2005.</p><p>SEAN GALLUP/GETTY IMAGES</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>414 I class action &#x25BA; Claudius</p><p>thus seen as antagonistic. Max Weber emphasized the importance of politi�  cal power and social status or prestige in maintaining class distinctions.  Despite controversies over the theory of class, there is general agreement  on the characteristics of the classes in modern capitalist societies. In many  cases the upper class has been distinguished by the possession of largely  inherited wealth, while the working class has consisted mostly of manual  labourers and semiskilled or unskilled workers, often in service indus�  tries, who earn moderate or low wages and have little access to inherited  wealth. The middle class includes the middle and upper levels of clerical  workers, those engaged in technical and professional occupations, super�  visors and managers, and such self-employed workers as small-scale  shopkeepers, businesspeople, and farmers. There is also often an urban  substratum of permanently jobless and underemployed workers termed  the �underclass.� See also bourgeoisie.</p><p>class action In law, an action in which a representative plaintiff sues  or a representative defendant is sued on behalf of a class of plaintiffs or  defendants who have the same interests in the litigation as their repre�  sentative and whose rights or liabilities can be better determined as a  group than in a series of individual suits. Class-action suits that received  national attention in the U.S. include a suit brought against manufactur�  ers of Agent Orange by Vietnam veterans exposed to the herbicide (settled  in 1984) and a suit concerning the effects of passive smoking brought  against tobacco firms (settled in 1997).</p><p>Classical architecture Architecture of ancient Greece and Rome,  especially from the 5 th century bc in Greece to the 3rd century ad in  Rome, that emphasized the column and pediment. Greek architecture was  based chiefly on the post-and-beam system, with columns carrying the load.  Timber construction was superseded by construction in marble and stone.  The column, a unit human in scale, was used as a module for all of a tem�  ple�s proportions. The Doric order, probably the earliest, remained the  favorite of the Greek mainland and western colonies. The Ionic order  developed in eastern Greece; on the mainland, it was used chiefly for  smaller temples and interiors. The greatest Greek architectural achieve�  ment was the Athens acropolis. By the late 5th century bc, the orders were  applied to such structures as stoas and theaters. The Hellenistic Age pro�  duced more elaborate and richly decorated architecture, with often colos�  sal buildings. Many of the great buildings were secular rather than  religious, and the Ionic and especially the newer Corinthian orders were  widely used. The Romans used the Greek orders and added two new ones  (Tuscan and Composite); the Corinthian was by far the most popular.  Roman architects used columns not only as functional bearing elements,  but also as applied (engaged) decoration. Though rigidly adhering to sym�  metry, the Romans used a variety of spatial forms. Whereas Greek temples  were isolated and almost always faced east-west, Roman temples were  oriented with respect to other buildings. Roman columns carried arches  as well as entablatures, permitting greater spatial freedom. The discovery  of concrete enormously facilitated construction using the arch, vault, and  dome, as in the Pantheon. Other public buildings included basilicas, baths  (see thermae), amphitheaters, and triumphal arches. Classical architecture  may also refer to architecture of later periods that employs Greek or  Roman forms.</p><p>classical economics School of economic thought largely centred in  Britain that originated with Adam Smith and reached maturity in the works  of David Ricardo and John Stuart Mill. The theories of the classical school  were mainly concerned with the dynamics of economic growth. Reacting  against mercantilism, classical economics emphasized economic freedom.  It stressed ideas such as laissez-faire and free competition. Many of the  fundamental principles of classical economics were set forth in Smith�s  Wealth of Nations (1776), in which he argued that a nation�s wealth was  greatest when its citizens pursued their own self-interest. Neoclassical  economists such as Alfred Marshall showed that the forces of supply and  demand would ration economic resources to their most effective uses.  Smith�s ideas were elaborated and refined by Ricardo, who formulated  the principle that the price of goods produced and sold under competitive  conditions tends to be proportionate to the labour costs incurred in pro�  ducing them. Mill�s Principles of Political Economy (1848) gave the ideas  greater currency by relating them to contemporary social conditions.  Among those who have modified classical economics to reach very dif�  ferent conclusions are Karl AAarx and John Maynard Keynes.</p><p>Classicism In the arts, the principles, historical tradition, aesthetic atti�  tudes, or style of the art of ancient Greece and Rome. The term may refer  either to work produced in antiquity or to later works inspired by those</p><p>of antiquity; the term Neoclassicism usually refers to art produced later  but inspired by antiquity. More broadly, Classicism refers to the adher�  ence to virtues regarded as characteristic of Classicism or as universally  and enduringly valid, including formal elegance and correctness, simplic�  ity, dignity, restraint, order, and proportion. Classicism is often opposed  to Romanticism. Periods of Classicism in literature, music, and the visual  arts have generally coincided.</p><p>Classicism and Neoclassicism Art-historical tradition or aesthetic  attitudes based on the art of ancient Greece and Rome. �Classicism� refers  to the art produced in antiquity or to later art inspired by that of antiq�  uity; �Neoclassicism� refers to art inspired by that of antiquity and thus  is contained within the broader meaning of �Classicism.� Classicism is  traditionally characterized by harmony, clarity, restraint, universality, and  idealism. In the visual arts, Classicism has generally denoted a preference  for line over colour, straight lines over curves, and the general over the  particular. The Italian Renaissance was the first period of thorough Clas�  sicism after antiquity. Neoclassicism became the dominant aesthetic  movement in Europe in the late 18th and early 19th centuries, as prac�  ticed by Antonio Canova and Jacques- Louis David. It bred a reaction in  favour of subjective feeling, longing for the sublime, and a taste for the  bizarre that came to be termed Romanticism. Recurring alternations  between Classical and non-Classical ideals have often characterized West�  ern aesthetics. See also Classical architecture.</p><p>Claude Lorrain Vklod-lo-'ra n \orig.

He became known as the master of the ideal land�  scape, a view of nature more beautiful and harmonious than nature itself;  his landscapes and coastal scenes contain architectural fragments and fig�  ures. His reputation is based particularly on his sensitivity to the tonal  values of light and atmosphere. By the 1630s he was well known and  successful, with illustrious patrons among the French and Italian aristoc�  racy.

In 1881 she moved with her family  to Paris and entered the Colarossi Academy. The following year she met  the renowned sculptor Auguste Rodin; she is best known today as his stu�  dent, collaborator, model, and mistress. She contributed whole figures and  parts of figures to Rodin�s projects, particularly The Gates of Hell (1880�  1900). Claudel exhibited her own work successfully at the official salons  and in galleries, but she also destroyed many pieces.

His brilliant  diplomatic career began in 1892, and he eventually served as ambassa�  dor to Japan (1921-27) and the U.S. (1927�33). At the same time he pur�  sued a literary career, expressing in poetry and drama his conception of  the grand design of creation. He reached his largest audience through  plays such as Break of Noon (1906), The Hostage (1911), Tidings Brought  to Mary (1912), and his masterpiece, The Satin Slipper (1929); recurring  themes in these works are human and divine love and the search for sal�  vation.

The tangent becomes the  endpoint of the vibrating string; thus the point where it strikes determines  the pitch. So-called fretted clavichords permit more than one tangent to  strike a single pair of strings (which somewhat limits the notes that can  be sounded simultaneously); unfretted clavichords use only one tangent  per pair of strings.

Under the Romans (see Roman Republic  and Empire) it became part of the province of Asia.</p><p>Clear Grits Political movement in Canada West (now Ontario). It devel�  oped in 1849 within the Reform Party in opposition to the province�s pre�  mier, Robert Baldwin, who advocated reforms that included the use of  crown lands to support the Protestant churches. It allegedly took its name  from the motto �All sand and no dirt, clear grit all the way through.� Its  early leader was Peter Perry; after his death in 1851, control gradually  passed to George Brown. It eventually joined other groups to form the  Liberal Party of Canada; the term �Grit� denotes a member of that party.</p><p>clearinghouse Institution established by firms engaged in similar  activities to enable them to offset transactions with one another in order  to limit payment settlements to net balances. Clearinghouses play an  important role in settling international payments and the transactions of  banks, railroads, and stock and commodity exchanges. Bank clearing�  houses are usually voluntary associations of local banks set up to simplify  the exchange of checks, drafts, and notes, as well as to settle balances.  Increasingly, the automated clearinghouse (ACH) is used to transfer funds  electronically. The clearinghouse idea was applied to various forms of  trade from an early time. The Amsterdam Exchange Bank, founded in  1609, became Europe�s largest clearinghouse and made the city an inter�  national financial centre. The first modern bank clearinghouse was estab�  lished in London in 1773. The first bank clearinghouse in the U.S. was  established in 1853.</p><p>cleavage Tendency of a crystalline substance to split into fragments  bounded by plane surfaces. Cleavage surfaces are seldom as flat as crys�  tal faces, but the angles between them are highly characteristic and valu�  able in identifying a crystalline material. Cleavage occurs on planes where  the atomic bonding forces are weakest; for example, galena cleaves par�  allel to all faces of a cube. Cleavage is described by its direction (as cubic,  prismatic, basal) and by the ease with which it is produced. A perfect  cleavage produces smooth, lustrous surfaces. Other degrees include dis�  tinct, imperfect, and difficult. See also fracture.</p><p>Cleese, John (Marwood) (b. Oct. 27, 1939, Weston-super-Mare,  Somerset, Eng.) British actor and screenwriter. He wrote and performed  comedy material for British television in the 1960s before helping create  the popular comedy show Monty Python�s Flying Circus (1969-74),  which later won a large U.S. following with its surreal brand of humour.  He cowrote and acted in the television series Fawlty Towers and collabo�  rated with the rest of the Monty Python troupe on films such as Monty  Python and the Holy Grail (1975), The Life of Brian (1979), and Monty  Python �s The Meaning of Life (1983). His other films include Silverado  (1985) and A Fish Called Wanda (1988).</p><p>clef French "key" Musical notation symbol at the beginning of a staff  to indicate the pitch of the notes on the staff. Clefs were originally letters,  identifying letter-named pitches, that were affixed to one or more of the  staff�s lines (thus providing a �key� to their identity). Knowing the iden�  tity of a single line permitted the musician to identify all the other lines  and spaces above and below. Clefs were first regularly used in the 12th  century. The Gothic letter forms of G and F evolved into the modem treble  and bass clefs, respectively; the letter C evolved into the rarer alto, tenor,  baritone, and soprano clefs.</p><p>cleft palate Fairly common congenital disorder in which a fissure forms  in the roof of the mouth. It may affect only the soft palate or extend through  the hard palate, so that the nasal cavity opens into the mouth. The sep�  tum (dividing wall) between the nostrils is often absent. Cleft lip, a fis�  sure in the lip beneath the nostril, or other abnormalities may accompany  it. Cleft palate limits the ability of an infant to suck, which may lead to  malnutrition, and causes speech problems in childhood. Surgical repair,  usually at about 18 months of age, forms an airtight separation between</p><p>nose and mouth. Speech training is still needed, and patients may have a  high risk of nose, ear, and sinus infections.</p><p>Cleisthenes Vklis-tho-.nezV of Athens (b. c. 570 bc �d. c. 508) Athe�  nian statesman and chief archon (525-524), regarded as the founder of  Athenian democracy. A member of the Alcmaeonid family, he allied him�  self with the Ecclesia (citizens� assembly) in 508 and imposed democratic  reforms by which the basis of organization was changed from family and  clan to locality. The four blood tribes were replaced by 10 local tribes,  each with representation from city, coast, and hill areas. The boule (rep�  resentative council) grew to 500 members.

A doctor before turning to politics, he served in  the Chamber of Deputies (1876-93), becoming a leader of the radical  republican bloc. He founded the newspapers La Justice (1880), L�Aurore  (1897), and L�Homme Libre (1913) and came to be ranked among the  foremost political writers of his time. His support for Alfred Dreyfus  brought him into favour, and he served in the Senate (1902-20). He served  as interior minister in 1906 and as premier (1906-09). During World War  1, at age 76, he became premier again (1917-20), and his steadfast pur�  suit of the war won him the title �Father of Victory.� He also helped frame  the postwar Treaty of Versailles, endeavouring to reconcile French inter�  ests with those of Britain and the U.S. Defeated in a presidential election  in 1920, he retired from politics.</p><p>Clemens, (William) Roger (b.

April 20, 1314, Roquemaure, Provence) Pope (1305-14), the  first to reside at Avignon, France. He became archbishop of Bordeaux in  1299 and was elected pope six years later. By creating a majority of  French cardinals, he ensured the election of a line of French popes. He  moved the seat of the papacy to Avignon, under pressure from King Philip  IV of France, who also forced Clement to annul Pope Boniface VIITs deci�  sions that were unfavourable to France. The king also compeled the pope  to dissolve the Templars, which Philip brutally suppressed. Clement  opposed Holy Roman Emperor Henry VII after 1313 and appointed the  king of Naples as imperial vicar on Henry�s death. His decretals, the  Clementinae, were a notable contribution to canon law.</p><p>"Mask of Medusa/' top view of stand  made by Ergotimos and painted by  Cleitias, c. 560 bc; in the Metropolitan  Museum of Art, New York City.</p><p>COURTESY OF THE METROPOLITAN MUSEUM OF ART, NEW  YORK, FLETCHER FUND, 1931</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Clement VI &#x25BA; Clergy Reserves I 417</p><p>Clement VI orig.

Archbishop of Sens  and Rouen, he was made cardinal in 1338 and was consecrated pope at  Avignon four years later (see Avignon papacy). He launched a Crusade  against Smyrna in 1344, ending the piracy of the Ottoman Turks. He also  restored papal authority in the Romagna region, which was disputed by  families of the Italian nobility. In exchange for his protection, Joan I of  Naples sold him Avignon. Clement opposed the Franciscan ascetics  known as the Spirituals, enlarged the papal palace, and fostered art and  scholarship.</p><p>Clement VII orig. Giulio de' Medici (b. May 26,1478, Florence�d.  Sept. 25, 1534, Rome) Pope (1523-34). The illegitimate son of Giuliano  de� Medici (see Medici family), he was raised by his uncle Lorenzo de�  Medici. In 1513 he was made archbishop of Florence and cardinal by his  cousin Pope Leo X. He commissioned art from Raphael and Michelangelo.  A weak and vacillating political figure mainly interested in advancing  Medici interests, Clement allied with France in 1527, which led to  Emperor Charles V�s sack of Rome. Clement�s indecisiveness complicated  Henry VIII�s request for an annulment of his marriage to Catherine of Ara�  gon, which contributed to Henry�s decision to break with the church in  Rome. His poor leadership also allowed the Reformation to develop fur�  ther.</p><p>Clement of Alexandria, Saint Latin Titus Flavius Clemens (b.</p><p>150, Athens�d. between 211 and 215, Palestine; Western feast day  November 23; Eastern feast day November 24) Christian apologist, mis�  sionary theologian to the Hellenistic world, and leader of the catechetical  school at Alexandria. He was converted to Christianity by Pantaenus, a  former Stoic who preceded him as head of the Alexandria school. Clem�  ent believed that philosophy was for the Greeks what the Law of Moses  was for the Jews, a preparatory discipline leading to the truth. He asserted  that men lived first as citizens of heaven and second as earthly citizens,  and he defended the right of an enslaved people to rebel against its oppres�  sors. Persecution by the emperor Septimius Severus in 201-202 obliged  him to leave Alexandria and take refuge with Alexander, bishop of Jerus�  alem. He was revered as a saint in the Latin church until 1586, when  doubts about his orthodoxy led to the removal of his name from the list  of Roman saints.</p><p>Clemente \kb-'men-ta\, Roberto (b.

Clemente played in the  minor leagues in his native land  before joining the Pittsburgh Pirates  in 1955. He led the National League  in hitting in 1961, 1964, 1965, and  1967, and batted .362 in two World  Series (1960, 1970). He was also  known for his fielding, throwing, and  base stealing. His career was cut  short when he died in the crash of an  airplane loaded with relief supplies  he had collected for Nicaraguan  earthquake victims.</p><p>Clementi, Muzio (b.

Taken to England at age 13 by a wealthy English traveler who had heard  his organ playing, he pursued a rigid course of music studies for seven  years while living on his patron�s country estate. His keyboard playing  and early sonatas gained him renown in London. In 1781 he and Wolf�  gang A. Mozart competed before the emperor, and he later toured exten�  sively as conductor and pianist. In 1798 he restarted a successful music�  publishing and piano-manufacturing firm. His piano pieces were highly  influential, and he taught many leading pianists. His works include more  than 100 piano sonatas and Gradus ad Parnassum, 3 vol.

An  Agiad (descendant from the legendary founders of Sparta), he ruled jointly  with Demaratus. In 510 he expelled the tyrant Hippias from Athens, then  supported the oligarchic party against the democratic Cleisthenes and</p><p>refused to help Athens combat Persia. His policies did much to solidify  Sparta�s position as the leading power in the Peloponnesus. He bribed the  oracle at Delphi to depose Demaratus, but he was discovered and fled.  Though reinstated, he went insane and committed suicide.</p><p>Cleomenes III (d. 219 bc) Agiad Spartan king (r. 235-222). Seeking  to institute social reforms, in 227 he canceled debts, redistributed land,  and restored the training of youth. He abolished the ephors and introduced  the patronomoi (board of six elders). His early attempts to weaken the  Achaean League (from 229) were successful, but in 222 his army fell at  Sellasia to a Macedonian force summoned by the league. He fled to Egypt,  where he was imprisoned but escaped (219); having failed to stir up revolt  in Alexandria, he committed suicide.</p><p>Cleon (d. 422 bc, Amphipolis, Macedonia) Athenian politician. The first  prominent representative of the merchant class in Athenian politics, he  became leader of Athens in 429 bc after the death of his enemy Pericles.  Advocating an offensive strategy in the Peloponnesian War, he proposed  that all citizens of the rebellious Mytilene be put to death and its women  and children enslaved; the measure passed but was reversed the next day.  He reached the summit of his fame when he captured the Spartan island of  Sphacteria, but he was killed by the Spartans while trying to retake Thrace.</p><p>Cleopatra in full Cleopatra VII Thea Philopator (b. 69�d.

Daughter of Ptolemy XII (b.</p><p>112?�d. 51 bc), she ruled with her  two brother-husbands, Ptolemy XIII  (r. 51^47) and Ptolemy XIV (r.</p><p>47^44), both of whom she had killed,  and with her son, Ptolemy XV, or  Caesarion (r. 44-30). She claimed  the latter was fathered by Julius Cae�  sar, who had become her lover after  entering Egypt in 48 bc in pursuit of  Pompey. She was with Caesar in  Rome when he was assassinated  (44), after which she returned to  Egypt to install her son on the throne.</p><p>She lured Mark Antony, Caesar�s  heir apparent, into marriage (36),  inviting the wrath of Octavian (later  Augustus), whose sister Antony had  earlier wed. She schemed against  and antagonized Antony�s friend  Herod the Great, thereby losing his support. At a magnificent celebration  in Alexandria after Antony�s Parthian campaign (36-34), he bestowed  Roman lands on his foreign wife and family. Octavian declared war on  Cleopatra and Antony and defeated their joint forces at the Battle of Actium  (31). Antony committed suicide and, after a failed attempt to beguile  Octavian, so, too, did Cleopatra, possibly by means of an asp.</p><p>Cleophrades Ude-'a-fro-.dezV Painter or Kleophrades Painter</p><p>(fl. late 6th-early 5th century bc, Greece) Greek vase painter.

Client computers provide an inter�  face to allow a computer user to request services of the server and to dis�  play the results the server returns. Servers wait for requests to arrive from  clients and then respond to them. Ideally, a server provides a standard�  ized transparent interface to clients so that clients need not be aware of  the specifics of the system (i.e., the hardware and software) that is pro�  viding the service. Today clients are often situated at workstations or on  personal computers, while servers are located elsewhere on the network,  usually on more powerful machines. This computing model is especially  effective when clients and the server each have distinct tasks that they  routinely perform. In hospital data processing, for example, a client com�  puter can be running an application program for entering patient infor�  mation while the server computer is running another program that  manages the database in which the information is permanently stored.  Many clients can access the server�s information simultaneously, and, at  the same time, a client computer can perform other tasks, such as send�  ing e-mail. Because both client and server computers are considered intel�  ligent devices, the client-server model is completely different from the  old �mainframe� model, which utilized a centralized mainframe computer  that performed all the tasks for its associated �dumb� terminals.</p><p>cliff dwelling Prehistoric, usually multistoried house of the ancestors  of present-day Pueblo Indians, built from c. 1000 along the sides or under  the overhangs of cliffs. The use of hand-hewn stone building blocks and  adobe mortar in these communal dwellings was unexcelled even in later  times. Rooms on upper levels could be entered either by doorways from  adjoining rooms or by ladders through holes in the ceilings; ground-floor  rooms could be entered only through the ceiling. It is thought that the cliff  dwellings were built as a defense against invading Navajo and Apache  tribes. They were deserted by the inhabitants around the end of the 13th  century. Many ruins remain, including notable ones at Canyon de Chelly  National Monument, Mesa Verde National Park, and Montezuma Castle  National Monument.</p><p>Clift, (Edward) Montgomery (b.

Climate is the sum of atmospheric elements (and their varia�  tions): solar radiation, temperature, humidity, clouds and precipitation  (type, frequency, and amount), atmospheric pressure, and wind (speed and  direction). To the nonspecialist, climate means expected or habitual  weather at a particular place and time of year. To the specialist, climate  also denotes the degree of variability of weather, and it includes not only  the atmosphere but also the hydrosphere, lithosphere, biosphere, and such  extraterrestrial factors as the sun. See also urban climate.</p><p>climatic adaptation In physical anthropology, the genetic adaptation  of human beings to different environmental conditions, such as extreme  cold, humid heat, desert habitat, and high altitudes. Extreme cold favours  short, round bodies with short arms and legs, flat faces with fat pads over  the sinuses, narrow noses, and a heavy layer of body fat. These adapta�  tions provide minimum surface area in relation to body mass for mini�  mum heat loss and protect the lungs and base of the brain against cold  air in the nasal passages. In conditions of humid heat, where body heat  must be dissipated, selection favours tall and thin bodies with maximum  surface area for heat radiation. A wide nose prevents warming of the air  in the nasal passages, and dark skin protects against harmful solar radia�  tion. The desert-adapted person must compensate for water loss through  sweating. A thin but not tall body minimizes both water needs and water  loss; skin pigmentation is moderate, since extreme pigmentation is good</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>climatology &#x25BA; ditoridectomy I 419</p><p>protection from the sun but allows absorption of heat from direct sun�  light, which must be lost by sweating.

Clinical psychologists evaluate  patients through interviews, observation, and psychological tests, and they  apply current research findings and methodologies in making diagnoses  and assigning treatments. Most clinical psychologists hold an academic  degree (Ph.D. or Psy.D.) rather than a medical degree (M.D.); they may  provide psychotherapy but cannot prescribe medications.

In 1992 he won the Democratic  Party�s presidential nomination despite charges of personal impropriety;  in the subsequent election he defeated the incumbent. Republican George  Bush, and independent candidate H. Ross Perot. As president, Clinton  obtained Senate ratification of the NAFTA accord in 1993. Along with his  wife, Hillary Rodham Clinton, he devised a plan to overhaul the U.S. health  care system, but it was rejected by Congress. He committed U.S. forces  to a peacekeeping initiative in Bosnia and Herzegovina. In 1994 the  Democrats lost control of Congress for the first time since 1954. Clinton  responded by offering a deficit-reduction plan while opposing efforts to  slow government spending on social programs. He defeated Robert Dole  to win reelection in 1996. In 1997 he helped broker a peace agreement  in Northern Ireland. He faced renewed charges of personal impropriety,  this time involving his relationship with a White House intern, Monica  Lewinsky; he denied the charges before a grand jury but ultimately  acknowledged �improper relations� in a televised address. In 1998 Clin�  ton became only the second president in history to be impeached. Charged  with perjury and obstruction of justice, he was acquitted by the Senate in  1999. His two terms saw sustained economic growth and successive bud�  get surpluses, the first in three decades.</p><p>Clinton, DeWitt (b. March 2, 1769, Little Britain, N.Y.�d. Feb. 11,  1828, Albany, N.Y., U.S.) U.S. politician. A nephew of George Clinton,  he practiced law and served as state senator (1798-1802, 1806-11), U.S.  senator (1802-03), mayor of New York City (1803-15 except for two  annual terms), lieutenant governor (1811-13), and governor (1817-23,  1825-28). He proposed the idea of a canal across New York state, and he  oversaw the construction of Erie Canal from 1816 until its opening in  1825. The canal assured the 19th-century development of New York City  as the major port of trade with the Midwest.</p><p>Clinton, George (b. July 26, 1739, Little Britain, N.Y.�d. April 20,  1812, Washington, D.C., U.S.) U.S. politician, fourth vice president of  the U.S. (1805-12). A veteran of the French and Indian War, he was a  leading member of the New York assembly (1768-75) and a delegate to  the Continental Congress (1775). As governor of New York (1777-95,  1801-04), he was a forceful leader and able administrator; he led the  opposition to the state�s adoption of the U.S. Constitution. A supporter of  Thomas Jefferson, he was twice elected vice president (with Jefferson and  James Madison); he died in office.</p><p>Clinton, Hillary Rodham orig. Hillary Diane Rodham (b. Oct.  26, 1947, Chicago, HI., U.S.) U.S. lawyer, first lady, and politician. She  attended Wellesley College and Yale Law School, from which she gradu�  ated first in her class. Her early professional interests focused on family  law and children�s rights. In 1975 she married her Yale classmate Bill  Clinton, and she became first lady of Arkansas on his election as gover�  nor in 1979. She was twice named one of America�s 100 most influential  lawyers by the National Law Journal. When her husband became presi�  dent (1993), she wielded power and influence almost unprecedented for  a first lady. As head of the Task Force on National Health Care Reform,  she proposed the first national health-care program in the U.S. but saw  the initiative defeated. In 2000 she was elected to the U.S. Senate from  New York, thereby becoming the first wife of a president to win elective  office.</p><p>Clinton, Sir Henry (b. April 16?, 1730?�d. Dec. 23, 1795, Cornwall,  Eng.) British commander in chief during the American Revolution. Com�  missioned in the British army in 1751, he went to North America in 1775  as second in command to William Howe. He commanded British troops  to victories in New York and then succeeded to the supreme command  on Howe�s retirement in 1778. He led an offensive in the Carolinas in  1780 and effected the fall of Charleston. On his return to New York, he  left Charles Cornwallis in charge of subsequent operations, which ulti�  mately resulted in the British surrender after the Siege of Yorktown. He  resigned in 1781 and returned to England, where he found himself blamed  for the Yorktown defeat.</p><p>cliometrics V.kll-o-'me-triksV Application of economic theory and sta�  tistical analysis to the study of history, developed by Robert W. Fogel (b.  1926) and Douglass C. North (b. 1920), who were awarded the Nobel  Prize for Economics in 1993 for their work. In Time on the Cross (1974),  Fogel used statistical analysis to examine the relationship between the  politics of American slavery and its profitability. North studied the link  between a market economy and legal and social institutions such as prop�  erty rights in such works as Structure and Change in Economic History  (1981).

Apparently  originating with the small, swift  coastal packet known as the Balti�  more clipper, the true clipper  evolved first in the U.S. (c. 1833) and  later in Britain. It was a long, slim,  graceful vessel with a projecting  bow, a streamlined hull, and an  exceptionally large spread of sail on  three tall masts. Clippers carried tea  from China and goldminers to Cali�  fornia. Famous clippers included the  American Flying Cloud and the Brit�  ish Cutty Sark. Though much faster  than the early steamships (already in use when the clipper appeared), they  were eventually outrun by improved steamship models and largely dis�  appeared from commercial use in the 1870s.</p><p>Clitias See Cleitias</p><p>ditoridectomy or female circumcision or female genital  mutilation Ritual surgical procedure ranging from drawing blood, to  removing the clitoris alone, to infibulation or Pharaonic circumcision�  removing the external genitals, joining the sides and leaving a small open�  ing.

Sept. 29, 1725, Styche,  Shropshire, Eng.�d. Nov. 22, 1774, London) British soldier and colonial  administrator. In 1743 he was sent to Madras (Chennai) for the East India  Company, where hostilities between it and the French East India Company  allowed him to demonstrate his military skills. He made a fortune and  returned to England in 1753 but was sent back to India in 1755. In 1757  his victory over the nawab of Bengal at the Battle of Plassey made him  the virtual master of Bengal. His first government, though tainted by cor�  ruption and duplicity, was a model of generalship and statecraft. Back in  England, he was elected to Parliament (1760) but failed to become a  national statesman. He returned to India as governor and commander in  chief of Bengal (1765-67). His reorganizing of the colony, including his  fight against corruption, helped establish Britain�s power in India. He  himself was attacked by Parliament on charges of corruption; though  exonerated, he later committed suicide.</p><p>cloaca \klo-'a-k3\ In vertebrates, common chamber and outlet into  which the intestinal, urinary, and genital tracts open. It is present in amphib�  ians, reptiles, birds, some fishes (e.g., sharks), and monotreme mammals but  is absent in placental mammals and most bony fishes. Certain animals (e.g.,  many reptiles and some birds, including ducks) have an accessory organ  (penis) within the cloaca that is used to direct the sperm into the female�s  cloaca. Most birds mate by joining their cloacas in a �cloacal kiss�; mus�  cular contractions transfer the sperm from the male to the female.</p><p>dock Machine or electronic device that measures and records time. Both  simple and elaborate clocks, as well as sundials, candle clocks, and sand�  glasses, were used for measuring time in ancient Egypt, Greece, and  Rome. The first mechanical clocks were weight-driven and perhaps were  invented for use in monasteries, where the disciplined life required a strict  rendering of time. The first European public clock that struck the hours  was erected in Milan in 1335, and the oldest surviving clocks are in  England (1386) and France (1389). The first domestic clocks appeared  late in the 14th century. About 1500 Peter Henlein, a German locksmith,</p><p>A classic pendulum clock. The power to run the clock comes from a slowly falling  weight (other mechanical clocks utilize a spring). The escapement prevents the  weight from falling all at once, and the swinging pendulum regulates the rate at  which the escapement allows the clock's wheels (gears) to turn. The time required  for a complete swing (period) of the pendulum depends only on the pendulum's  length: a 39-in. (990-mm) pendulum has a period of one second.</p><p>� MERRIAM-WEBSTER INC.</p><p>began to make the first portable timepieces, small clocks driven by a  spring. Christiaan Huygens invented pendulum clocks in 1656. Big Ben,  the great clock at Westminster in London, was installed in 1859 and is  the standard for all accurate tower pendulum clocks. The most accurate  mechanical timekeepers (within a few thousandths of a second per day)  are clocks with short pendulums (about 39 in. [or 990 mm]). In 1929 the  vibration of a quartz crystal was first applied to timekeeping; the maxi�  mum error of an observatory quartz-crystal clock is only a few ten-  thousandths of a second per day. The first atomic clock went into operation  in 1951. Atomic clocks, regulated by the natural periodic behaviour of a  system of atoms (such as vibrations or emission of radiation), can have  accuracies exceeding one billionth of a second per day, making them the  most accurate clocks yet invented.</p><p>Clodion \klod-'yo n \ orig.

In 1759 he won the  grand prize at the Royal Academy  and embarked on a successful career,  first in Rome and then in Paris,  where he exhibited regularly at the  Salon. He excelled at small statu�  ettes and terra-cotta figures of  nymphs, satyrs, and groups.

Cloning is  fundamental to most living things, since the body cells of plants and ani�  mals are clones that come ultimately from a single fertilized egg. More  narrowly, the term refers to an individual organism grown from a single  body cell of its parent that is genetically identical to the parent. Cloning  has been commonplace in horticulture since ancient times; many variet�  ies of plants are cloned simply by obtaining cuttings of their leaves, stems,  or roots and replanting them. The body cells of adult humans and other  animals are routinely cultured as clones in the laboratory. Entire frogs and  mice have been successfully cloned from embryonic cells. British  researchers led by Ian Wilmut achieved the first success in cloning an  adult mammal in 1996. Having already produced clones from sheep  embryos, they were able to produce a lamb (Dolly) using DNA from an  adult sheep. The practical applications of cloning are economically prom�  ising but philosophically unsettling.</p><p>Close, Chuck (b. July 5, 1940, Monroe, Wash., U.S.) U.S. artist.

Photorealist  paintings. Throughout his career, he concentrated on portraits�from the  neck up�based on photographs he had taken. In addition to self-portraits,  the paintings were usually of friends, many of whom were prominent in  the art world. He experimented with a variety of media and techniques,  including using fingerprints and colourful tiles that, seen from a distance,  combined into an illusionistic whole.

High  clouds, which are found at mean heights of 45,000-16,500 ft (13-5 km),  are, from highest to lowest, cirrus, cirrocumulus, and cirrostratus. Middle  clouds, at 23,000-6,500 ft (7-2 km), are altocumulus, altostratus, and  nimbostratus. Low clouds, at 6,500-0 ft (2-0 km), are stratocumulus,  stratus, cumulus, and cumulonimbus.

With a strong  aroma and hot and pungent taste, they are used to flavour many foods.  Clove oil is sometimes used as a local anesthetic for toothaches. Eugenol,  its principal ingredient, is used in germicides, perfumes, and mouth�  washes, in the synthesis of vanillin, and as a sweetener or flavour inten-  sifier.</p><p>clover Any legume of the genus Trifolium, composed of 300 or more  annual and perennial species, found  in most temperate and subtropical  regions.

The son of  Childeric I, king of the Salian Franks, Clovis was still a pagan when he  conquered the last Roman ruler in Gaul at Soissons (486). He extended  his rule as far south as Paris by 494. His wife, Clotilda, was a Catholic  princess later recognized as a saint. She sought to convert Clovis to her  faith. According to Gregory of Tours, during a faltering campaign against  the Alamanni in 496, Clovis invoked his wife�s god and saw defeat turned  to victory. He was baptized at Reims two years later, and he credited St.  Martin of Tours for his victory over the Visigoths. Although he was the  first Germanic king to accept Catholic Christianity, Clovis expressed inter�  est in Arian Christianity before converting to his wife�s religion. He pro�  mulgated the legal code known as the Lex Salica. He is traditionally  regarded as the founder of the French monarchy and the original French  champion of the Christian faith.</p><p>Clovis complex Widely distributed prehistoric culture of North  America characterized by leaf-shaped flint projectile points with fluted  sides.

Established as a pious donation for the cure of the souls of the duke  and his wife and family, the monastery at Cluny came to offer a more  austere reading of the Benedictine Rule. It was dedicated to the apostles  St. Peter and St. Paul, and in practice it came under the protection of the  pope. William also established the independence of the monastery from  all temporal rulers, religious or secular, and allowed the monks to elect  the abbot. These liberties enabled the community to develop its empha�  sis on the liturgy and prayers for the dead, which inspired a reputation for  holiness and attracted numerous benefactors. Cluniac monks were sent to  reform monasteries throughout Europe and created a great web of related  communities. Cluny�s influence on the church in the 11th�12th century  has been widely recognized, and its abbots were greatly esteemed. Its  predominance was eroded by the rise of the Cistercian order, and in the  later Middle Ages the monastery declined. It was suppressed during the  French Revolution and closed in 1790. Its Romanesque Basilica of St. Peter  and St. Paul (largely demolished in the 19th century) was the world�s  largest church until the erection of Saint Peter's Basilica.</p><p>Clurman, Harold (Edgar) (b.

In the medusa (jellyfish) form, the tentacles and  mouth face downward. The outer cell layer (ectoderm) and inner cell layer (endo-  derm) are separated by the jellylike mesoglea. The mouth is also used to expel  wastes. Digestion begins within the gastrovascular cavity and is completed by endo-  derm cells.</p><p>� MERRIAM-WEBSTER INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Cnidus &#x25BA; coati I 423</p><p>thread used for stinging, paralyzing, and capturing prey. Cnidarians have  no well-defined separate respiratory, circulatory, or excretory organs; their  tissues, composed of two cell layers, surround a cavity known as a coe-  lenteron (gastrovascular cavity), which is the basic internal organ. Ten�  tacles surrounding the mouth are used to capture and ingest food.  Cnidarians are carnivorous, feeding mostly on zooplankton but also on  small crustaceans, fish eggs, worms, smaller cnidarians, and even small  fish. Cnidarians range in size from nearly microscopic to more than 100  ft (30 m) long and more than a ton (910 kg) in weight. There are two  basic body forms: the polyp (e.g., coral) and the medusa (e.g., jellyfish).

An  important commercial centre and the home of a renowned medical school,  Cnidus was one of six cities in the Dorian Hexapolis. It came under the  control of the Persian Achaemenian dynasty after 546 bc. A democracy  in the 4th century bc, it fell under Ptolemaic control in the 3rd century  bc. A free city within the Roman province of Asia, it lasted until the 7th  century ad, when it was abandoned. Excavation has revealed numerous  public buildings, including the Temple of Aphrodite, where fragments of  the celebrated statue of Aphrodite by Praxiteles were discovered.</p><p>CNN or Cable News Network Subsidiary company of Turner  Broadcasting Systems. It was created by Ted Turner in 1980 to present  24-hour live news broadcasts, using satellites to transmit reports from  news bureaus around the world. CNN became prominent in 1991 with its  coverage of the Persian Gulf War. The company also operates the news  channels Headline News and CNN International.

The coach originated in the 15th cen�  tury in Hungary (where kocsi originally meant �wagon from the town of  Kocs�). It was introduced in England in the mid-16th century. Coaches  were used as public conveyances with inside seats for passengers (as in the  stagecoach) and for mail delivery. They were used mainly in European cit�  ies into the 18th century, when the private carriage became more common.</p><p>Coachella \kd-'chel-3\ Valley Valley, southern California, U.S. Part  of the Colorado Desert, the 15-mi- (24-km-) wide valley stretches 45 mi  (72 km) between the Little San Bernardino Mountains and the San Jacinto  and Santa Rosa mountains. A productive agricultural region, it also has  popular desert resorts, including Palm Springs.</p><p>coagulation Process of forming a blood clot to prevent blood loss from  a ruptured vessel. A damaged blood vessel stimulates activation of clot�  ting factors, eventually leading to the formation of long, sticky threads of  fibrin. These make a mesh that traps platelets, blood cells, and plasma.  This meshwork soon contracts into a resilient clot that can withstand the  friction of blood flow. Under abnormal circumstances, clots can form in  an intact vessel and may block it. See also anticoagulant.</p><p>Coahuila V.ko-a-'we-laX State (pop., 2000: 2,298,070), northeastern  Mexico. It covers 57,908 sq mi (149,982 sq km), and its capital is Saltillo.  Coahuila occupies a roughly broken plateau intersected by several moun�  tain ranges. The first Spanish settlement in the region was at Saltillo in  1575. Coahuila and Texas formed a single state (1824-36) until Texas  declared its independence. In 1857 Coahuila was combined with Nuevo  Leon, and in 1868 it became a separate state. Its economy is based on  livestock raising, agriculture, and mining; southern Coahuila has long  been known for the wine and brandy it produces.</p><p>coal Solid, usually black but sometimes brown, carbon-rich material that  occurs in stratified sedimentary deposits. One of the most important fos�  sil fuels, it is found in many parts of the world. Coal is formed by heat  and pressure over millions of years on vegetation deposited in ancient  shallow swamps (see peat). It varies in density, porosity, hardness, and  reflectivity. The major types are lignite, subbituminous, bituminous, and  anthracite. Coal has long been used as fuel, for power generation, for the  production of COKE, and as a source of various compounds used in syn�  thesizing dyes, solvents, and drugs. The search for alternative energy  sources has periodically revived interest in the conversion of coal into  liquid fuels; technologies for coal liquefaction have been known since  early in the 20th century.</p><p>Coal Measures Major division of Upper Carboniferous (323-290 mil�  lion years ago) rocks and time in Great Britain. The Coal Measures  account for much of England�s coal production. The deposits consist  largely of bituminous coal, though anthracite coals occur in southern Wales.</p><p>Though local variation in the coal seams occurs, great uniformity is evi�  dent on a regional scale, and some coal beds can be identified through�  out Great Britain and even on the European continent.</p><p>coal mining Extraction of coal deposits from the Earth�s surface and  from underground. Because coal was the basic energy source that fueled  the Industrial Revolution, the resulting industrial growth supported the  large-scale exploitation of coal deposits. In the late 20th century, open pit  mines replaced underground mines as the principal source of coal in the  industrial nations. The MINING of coal from surface and underground  deposits today is a highly productive, mechanized operation.</p><p>Coalsack Dark nebula in the Crux constellation (Southern Cross). It  reduces the brightness of stars beyond it by 1�1.5 magnitudes. Easily vis�  ible against a starry background, it is probably about 550-600 light-years  from Earth and 20-30 light-years in diameter. It figures in legends of  peoples of the Southern Hemisphere and has been known to Europeans  since c. 1500. The Northern Coalsack, in the constellation Cygnus, is  similar in nature and appearance but somewhat less obvious.</p><p>coarctation of the aorta See coarctation of the aorta</p><p>Coase \'koz\, Ronald (Harry) (b. Dec. 29, 1910, Willesden, Mid�  dlesex, Eng.) British-U.S. economist. He received his doctorate from the  London School of Economics and taught principally there and the Uni�  versity of Chicago. In his best-known paper, �The Problem of Social  Cost� (1960), he challenged the classical logic of prohibiting behaviour  that damages others. He argued that legal scholars should focus on the  importance of an efficient marketplace and on negotiation rather than liti�  gation. He was awarded the Nobel Prize in 1991.</p><p>coast or shore Broad area of land that borders the sea. The coastlines  of the world�s continents measure about 193,000 mi (312,000 km). They  have undergone shifts in position and changes in shape over geologic time  because of substantial changes in the relative levels of land and sea. Other  factors that alter coasts are erosion processes such as wave action and  weathering, deposition of rock debris by currents, and tectonic activity.  Coastal features result largely from the interaction and relative intensity  of these processes, though the type and structure of the underlying rocks  also play a part.</p><p>coast guard Naval force that polices compliance with a nation�s mari�  time laws and assists vessels wrecked or in distress on or near its coasts.  First established in the early 19th century to discourage smuggling, coast  guards may maintain lighthouses, buoys, and other navigational aids and  provide emergency aid to merchant sailors and to victims of natural disas�  ters. Duties may include icebreaking in inland waterways and the collec�  tion and broadcasting of meteorological data concerning floods and  storms. In several European countries, volunteer lifeboat associations  handle coast-guard duties.</p><p>Coast Ranges or Pacific Coast Ranges Series of ranges, along  the Pacific coast of North America. They run from southern California  through Oregon and into west-central Washington. The ranges� average  elevation is about 3,300 ft (1,000 m) above sea level, but some peaks and  ridges rise to more than 6,600 ft (2,000 m). Giant redwoods dominate the  forests along the coasts of southern Oregon and northern California. The  Coast Mountains of British Columbia are not a continuation of the U.S.  Coast Ranges but of the Cascade Range.</p><p>coat of arms or shield of arms Heraldic device dating to the 12th  century in Europe. It was originally a cloth tunic worn over or in place  of armour to establish identity in  battle. In the full armorial achieve�  ment the distinctively patterned  shield is ornamented with a crest,  helmet, mantling, motto, crown,  wreath, and supporters and rests  upon a compartment. Arms were  later adopted as emblems for  schools, churches, guilds, and corpo�  rations to reflect their origins or his�  tories.

(73-136 cm) in length  (half of which is tail) and weighs 10-24 lbs (4.5-11 kg). Females and  young commonly live in bands of five to 40; males are solitary, joining  bands only during mating season. Coatis feed by day on seeds, fruits, eggs,  and small animals.</p><p>coaxial cable or coax Self-shielded cable used for transmission of  communications signals, such as those for television, telephone, or com�  puter networks. A coaxial cable consists of two conductors laid concen�  trically along the same axis. One conducting wire is surrounded by a  dielectric insulator, which is in turn surrounded by the other, outer con�  ductor, producing an electrically shielded transmission circuit. The whole  cable is wrapped in a protective plastic sheathing. The signal propagates  within the dielectric insulator, while the associated current flow is  restricted to adjacent surfaces of the inner and outer conductors. As a  result, coaxial cable has very low radiation losses and low susceptibility  to external interference.</p><p>Cobain, Kurt (b. Feb. 20, 1967, Aberdeen, Wash., U.S.�d. April 5,  1994, Seattle, Wash.) U.S. rock musician. He formed the rock trio Nir�  vana in Aberdeen in 1986. The band, whose style derived from punk rock,  combined the fury of that genre with anguished lyrics, a style that,  together with their tom jeans and flannel shirts, became known as grunge  rock. Their first album, Bleach (1989), was followed by Nevermind  (1991), featuring the hit �Smells Like Teen Spirit�; it was the first punk-  oriented album to achieve popularity with a mainstream audience. Cobain  was elevated to prominence, but with the album In Utero (1993) he railed  against his fame. Known for his self-destructive behaviour and heroin use,  he shot and killed himself in his home.</p><p>cobalt Metallic chemical element, one of the transition elements, chemical  symbol Co, atomic number 27. Widely dispersed in small amounts in  many minerals and ores, this magnetic, silvery white metal with a faint blu�  ish tinge is used mostly for special alloys (e.g., alnico, tool steel) with  exacting applications. At valence 2 or 3 it forms numerous coordination  complexes. One is vitamin B 12 (cyanocobalamin; see vitamin B complex).  Cobalt and its compounds are used in electroplating and colouring ceram�  ics and glass and as lamp filaments, catalysts, a trace element in fertilizers,  and paint and varnish driers. The pigment cobalt blue has a variable com�  position, roughly that of cobalt oxide plus alumina. A radioactive isotope  of cobalt emits penetrating gamma rays that are used in radiation therapy.</p><p>Cobb, Howell (b. Sept. 7, 1815, Jefferson county, Ga., U.S.�d. Oct.  9, 1868, New York, N.Y.) U.S. politician. He served in the U.S. House of  Representatives (1843-51, 1855-57), where he promoted Southern inter�  ests by supporting the annexation of Texas and the Mexican War. Nev�  ertheless, he also supported the Compromise of 1850, which was favoured  by the North. He served as governor of Georgia (1851-53). He supported  the presidential candidacy of James Buchanan, who appointed him secre�  tary of the treasury (1857-60). An opponent of Abraham Lincoln, he  became a spokesman for secession. He served as chairman of the con�  vention called to organize the Confederacy, then organized his own regi�  ment and led it to the front in the American Civil War.</p><p>Cobb, Ty in full Tyrus Raymond Cobb (b. Dec. 18, 1886, Narrows,  Ga., U.S.�d. July 17, 1961, Atlanta,</p><p>Ga.) U.S. baseball player, one of the  greatest offensive players and per�  haps the fiercest competitor in base�  ball history. He joined the Detroit  Tigers in 1905, batting left-handed  but throwing right-handed. He spent  22 seasons as an outfielder with the  Detroit Tigers, then managed them  from 1921 to 1926. His record for  career batting average (.366) remains  unbroken; those for runs batted in  (1,937), runs (2,245), and hits  (4,189) stood for many years. He  batted at least .300 for 23 straight  seasons, an all-time record, and his  three years of batting over .400 also  represent a record. His career record  of 892 stolen bases (partly the result</p><p>of the brutality with which he used his cleats) was surpassed only in 1979.  In the first election to the Baseball Hall of Fame in 1936, Cobb received  the most votes.</p><p>Cobbett, William (b. March 9, 1763, Farnham, Surrey, Eng.�d. June  18, 1835, London) English journalist. He joined the army and served in  Canada (1785-91). He lived in the U.S. (1794-1800), where he launched  his career as a journalist, fiercely attacking the spirit and practice of  American democracy and winning himself the nickname �Peter Porcu�  pine.� He returned to England and founded the weekly Political Register  (1802), which he published until his death. He championed traditional  rural values as England entered the Industrial Revolution; his reactionary  views of the ideal society struck a powerful chord of nostalgia, and he  also criticized corruption, harsh laws, and low wages.</p><p>Cobden, Richard (b. June 3, 1804, Dunford Farm, near Midhurst,  Sussex, Eng.�d. April 2, 1865, Lon�  don) British politician. He gained an  independent fortune in the calico  wholesale business. After travel to  study trade policies in Europe and  the U.S., he wrote pamphlets on  international free trade. He was  elected to Parliament (1841-57,</p><p>1859-65) and, with his close associ�  ate, John Bright, successfully fought  to repeal the Corn Laws. In the 1850s  he argued for friendly relations with  Russia, even after the Crimean War  had begun. He helped negotiate a  commercial treaty with France  (1860) that included a most�  favoured-nation clause later dupli�  cated in other treaties.</p><p>cobia Vko-bo-oX Swift-moving,  slim marine game fish ( Rachycen-  tron canadum ), the only member of  the family Rachycentridae. Found in  most warm oceans, this voracious predator may grow as long as 6 ft (1.8  m) and weigh 150 lbs (70 kg) or more. It has a jutting lower jaw, a rather  flat head, and light-brown sides, each with two lengthwise, brown stripes.

COBOL was created to fulfill two major objectives:  portability (ability of programs to be run with minimum modification on  computers from different manufacturers) and readability (ease with which  a program can be read like ordinary English). It ceased to be widely used  in the 1990s.</p><p>cobra Any of several highly venomous elapid snakes that expand their  neck ribs to form a hood. They are  found in warm regions of Africa,</p><p>Australia, and Asia. Cobra bites are  fatal in about 10% of human cases.</p><p>Cobras feed primarily on small verte�  brates. The Indian cobra (Naja naja)  kills several thousand people annu�  ally, mostly because it enters houses  to catch rats. The king cobra  (Ophiophagus hannah) is the world�s  largest venomous snake, often more  than 12 ft (3.5 m) long. Some African  cobras can spit their venom more than 6 ft (1.8 m). Cobras are favourites of  snake charmers, who, by their movements rather than their music, tease the  deaf snakes into assuming the upreared defense posture.</p><p>Cobra Expressionist group of painters formed in Paris in 1948.

June 11, 1882, Boston, Mass., U.S.�d.  Nov. 23, 1966, Rhos-on-Sea, Denbighshire, Wales) U.S.-born British pho�  tographer. He did not take up photography seriously until he met Edward  Steichen in 1899. In 1902 he opened a studio in New York City and joined  the Photo-Secession. In 1904 he went to London with a commission to  photograph celebrities; his memorable portraits include those of Auguste  Rodin, Henry James, and George Bernard Shaw posing as Rodin�s Thinker.  In 1917, influenced by Cubism and Futurism, he produced the first photo�  graphs depicting abstract compositions.</p><p>coca Tropical shrub ( Erythroxylum coca ) of the family Erythroxylaceae.  It is native to the eastern Andes  Mountains but cultivated in Africa,  northern South America, Southeast  Asia, and Taiwan. Its leaves are the  source of cocaine and several other  alkaloids. Coca thrives best in hot,  damp environments, such as forest  clearings; but the leaves most pre�  ferred are obtained in drier localities,  on the sides of hills. The composition  of different specimens of coca leaves  is highly variable. Good samples  have a strong tealike odor and a  pleasant, pungent taste. When  chewed, coca leaves produce a sense of warmth in the mouth; because of  their potent stimulant and appetite-depressant effects, coca has been used  for centuries by South American peasants to ease the effects of punishing  physical labor.</p><p>Coca-Cola Co. U.S. corporation known for manufacturing the syrup  and concentrate for the soft drink Coca-Cola, the most popular branded  drink in the world. Coca-Cola was invented as a tonic by an Atlanta, Ga.,  pharmacist, John S. Pemberton (1831-88); it included cocaine (removed  in 1905) and caffeine-rich extracts of the kola nut. Another Atlanta phar�  macist, Asa Griggs Candler (1851-1929), acquired the formula and in  1892 founded the Coca-Cola Co., which he built into a commercial  empire. Candler saw the product as syrup to be combined with carbon�  ated water at a soda fountain; he did not anticipate the success of the  bottled product, and as a result bottling operations were run by franchi�  sees. After World War II the company began to manufacture other bev�  erages, and in the early 21st century its product line included root beer,  bottled water, juices, and sports drinks. Its corporate headquarters are in  Atlanta.</p><p>cocaine Heterocyclic compound (C 17 H 2 iN 0 4 ), an alkaloid obtained from  coca leaves. It has legal uses in medicine and dentistry as a local anes�  thetic but far more is used illegally, usually as the hydrochloride. When  sniffed in small amounts, cocaine produces feelings of well-being and  euphoria, decreased appetite, relief from fatigue, and increased mental  alertness. Larger amounts or prolonged use can damage the heart and nasal  structures and cause seizures. In altered, more potent, cheaper forms (free-  base, crack), cocaine is injected or smoked and is extremely addictive (see  drug addiction) and detrimental to health. Prolonged or compulsive use of  any form of purified cocaine can cause severe personality disturbances,  inability to sleep, appetite loss, and paranoid psychosis.</p><p>coccus \'ka-kos\ Spherical bacterium. Many species have characteristic  arrangements that are useful in identification. Pairs of cocci are called  diplococci; rows or chains, streptococci (see streptococcus); grapelike  clusters, staphylococci (see staphylococcus); packets of eight or more  cells, sarcinae; and groups of four cells in a square arrangement, tetrads.  These characteristic groupings occur as a result of variations in the repro�  duction process.</p><p>Cochabamba \,ko-cha- , bam-ba\ City (pop., 2001: 516,683), central  Bolivia. Founded as Villa de Oropeza in 1574, it received city status in  1786 and was renamed Cochabamba (Khocha Pampa), a name in the Que-  chua language that means �plain full of small lakes.� A favourable climate  and attractive setting have helped make it Bolivia�s third largest city. It is</p><p>the chief distribution point for eastern Bolivia.

June 8, 1874, Chiricahua Apache Reservation,  Ariz.Terr., U.S.) Chiricahua Apache chief who led the resistance to white  incursions into the American Southwest. Nothing is known of his birth or  early life. His people remained at peace with white settlers through the  1850s, but in 1861 skirmishes and eventually all-out war broke out  between the Apache and the U.S. Army. Cochise and his followers eluded  capture for 10 years. By 1872, however, most Apache, including Cochise,  had agreed to move onto reservations.</p><p>Cochran, Jacqueline (b. 1910?, Pensacola, Fla., U.S.�d. Aug. 9,  1980, Indio, Calif.) U.S. aviator.

In 1938 she set a speed record for  women flying across North America. In World War II she trained women  transport pilots in the British and later the U.S. Air Force auxiliaries. In  1953 she broke the world speed record (for both men and women) in a  jet, and in 1961 she became the first woman to fly at twice the speed of  sound.</p><p>cockatiel Vka-ko-.telX Crested, small, gray Australian parrot ( Nymphi -  cus hollandicus). It has a yellow head, red ear patches, and a heavy beak  used to crack nuts. The cockatiel is in the same family (Cacatuidae) as  the larger cockatoo. About 13 in.

He served in the House of  Commons (1847-56), as attorney general (1851-56), and as chief justice  of the Court of Common Pleas (1856-59) before being appointed to the  Queen�s Bench (1859-74). He served on the panel that decided the Ala�  bama claims and finally served as lord chief justice of England (1874-80).  He is best known for his tests of obscenity (to be obscene, the material in  question had to be proved to �deprave and corrupt� those exposed to it)  and insanity (to be insane, a criminal defendant had to be proved unwit�  ting of the �nature and quality� of his criminal act or incapable of rec�  ognizing it as wrong).</p><p>cockchafer Large European beetle ( Melolontha melolontha ) that dam�  ages foliage, flowers, and fruit as an adult and plant roots as a larva.

Covering some 500 sq mi (1,300 sq km), the area has  typical karst topography, with conical hills rising above sinkholes with  sharp, precipitous sides (called �cockpits�). This inhospitable terrain pro�  vided refuge for runaway slaves, who became guerrilla fighters when the  English conquered Jamaica in 1665. Their descendants today number  about 5,000 and still maintain some independence: all land belongs to the  community, they pay no taxes, and the central government may interfere  only in case of a capital crime.</p><p>cockroach or roach Any of more  order Blattaria, order Dictyoptera)  that are among the most primitive  living, winged insects and among the  oldest (more than 320 million years  old) fossil insects. Cockroaches have  a flattened, oval body; long, thread�  like antennae; and a shining, leath�  ery, black or brown covering. They  prefer a warm, humid, dark environ�  ment and are usually found in tropi�  cal or other mild climates, but have  become widespread in heated build�  ings, especially city apartment build�  ings, in the temperate zone, and infestations can be severe. Only a few  species have become pests. Cockroaches eat both animal and plant mate�  rial. The American cockroach is up to about 2 in. (30-50 mm) long. The  German cockroach (less than 0.5 in., or about 12 mm, long) is a common  household pest which has been spread throughout the world by ship.</p><p>Coco River formerly Segovia River River, Central America.

Only the lower 140 mi (225 km) are navigable.</p><p>coconut palm Tree ( Cocos nucifera) of the palm family, one of the most  important crops of the tropics. Its slender, leaning, ringed trunk rises from  a swollen base and is topped by a graceful crown of giant, feathery leaves.  The large ovoid or ellipsoid mature fruits have a thick, fibrous husk sur�  rounding the familiar single-seeded nut. The nut contains a white and  somewhat sweet meat, which is eaten raw; coconut oil is extracted from the  meat. The nutritious liquid �milk� at the centre may be drunk directly from  the nut. The husk provides coir, a fibre highly resistant to salt water that is  used in the manufacture of ropes, mats, baskets, brushes, and brooms. The  nutshells are used as containers and often decoratively carved.</p><p>Cocos Islands or Keeling Islands Territory (pop., 1996: 558) of  Australia. Lying in the eastern Indian Ocean about 580 mi (930 km)  southwest of Java, it consists of two isolated atolls and 27 small coral  islets and has a total land area of 5.6 sq mi (14.4 sq km). They were dis�  covered in 1609 by William Keeling and first settled in 1826. Declared a  British possession in 1857, the Cocos at times came under the govern�  ment of Ceylon but ultimately passed to Australia in 1955. In 1984 the  residents voted to merge with Australia.</p><p>Cocteau \kok-'t6\, Jean (b. July 5, 1889, Maisons-Laffitte, near Paris,  France�d. Oct. 11, 1963, Milly-la-Foret, near Paris) French poet, play�</p><p>wright, and film director. He pub�  lished his first collection of poems,</p><p>La Lampe d�Aladin, at age 19. He  converted to Catholicism early but  soon renounced religion. During  World War I he was an ambulance  driver on the Belgian front, the set�  ting for the novel Thomas  Timposteur (1923). In the years  when he was addicted to opium, he  produced some of his most important  works, including the play Orphee  (1926) and the novel Les Enfants ter-  ribles (1929). His greatest play is  thought to be The Infernal Machine  (1934). His first film was The Blood  of a Poet (1930); he returned to film-  making in the 1940s, first as a  screenwriter and then as a director,  and made such admired films as  Beauty and the Beast (1945), Orphee  (1949), and Le Testament d�Orphee  (1960). Musically, Cocteau was closely associated with the group of com�  posers known as Les Six; among other collaborations, he provided ballet  scenarios for Erik Satie (Parade, 1917) and Darius Milhaud (Le Boeuf sur  le toit, 1920) and wrote librettos for Igor Stravinsky (Oedipus, 1927) and  Milhaud (La Voix humaine, 1930). Also an artist, he illustrated numerous  books with his vivid drawings, and he worked as a designer as well.</p><p>cod Large and economically important marine fish (Gadus morhua, fam�  ily Gadidae) found on both sides of the North Atlantic, usually near the  bottom in cold water. It ranges from inshore regions to deep waters. It is  valued for its edible flesh, the oil of its liver, and other products. The cod  is dark-spotted and ranges from greenish or grayish to brown or black�  ish; it may also be dull to bright red. It usually weighs up to about 25 lbs  (11.5 kg) but can reach a maximum length and weight of more than 6 ft  (1.8 m) and 200 lbs (91 kg). It feeds largely on other fishes and various  invertebrates.</p><p>Cod, Cape See Cape Cod</p><p>Coddington, William (b. 1601, Boston, Lincolnshire, Eng.�d. Nov.  1, 1678, Rhode Island) American colonial governor and religious dissi�  dent. An official in the Massachusetts Bay Company, he immigrated to  Massachusetts in 1630 and served in the colonial legislature. As a fol�  lower of Anne Hutchinson, he was obliged to leave the colony for Aquid-  neck Island (Rhode Island), where he established settlements at  Portsmouth and Newport. Although he hoped to maintain Aquidneck as  a separate colony, it was combined with Roger Williams�s Providence  plantation in 1644. Later acknowledging Rhode Island�s unity, he served  as its governor in 1674, 1675, and 1678.</p><p>code System of symbols and rules used for expressing information  according to an unvarying rule for replacing a piece of information from  one system, such as a letter, word, or phrase, with an arbitrarily selected  equivalent in another system. Substitution ciphers are similar to codes  except that the rule for replacing the information is known only to the  transmitter and the intended recipient of the information. Binary code and  other machine languages used in digital computers are examples of codes.  Elaborate commercial codes were developed during the early 20th cen�  tury (see Jean M.E. Baudot, Samuel F. B. Morse). In recent years more  advanced codes have been developed to accommodate computer data and  satellite communications.

It  exerts its effects by acting on the central nervous system (brain and spi�  nal cord). Chemically it is methylmorphine, the methyl ether of morphine,  an alkaloid of the phenanthrene type; its action is weaker than that of  moiphine, and it is less likely to lead to drug addiction.</p><p>codependency An extreme dependency by one person on another who  is suffering from an addiction.

The earliest type of manuscript  in the form of a modem book (i.e., a collection of pages stitched together  along one side), the codex replaced earlier rolls of papyrus and wax tab�  lets. Among its advantages, it could be opened at once to any point in the  text, it permitted writing on both sides of the leaf, and it could contain  long texts. The oldest extant Greek codex is the Codex Sinaiticus (4th  century ad), a biblical manuscript. Codices were developed separately by  pre-Columbian Mesoamericans after c. ad 1000.</p><p>Codium Vko-de-3m\ Genus of marine green algae usually found in deep  pools along rocky coasts. The threadlike branches are often woven  together to form a velvety body sometimes longer than 12 in. (30 cm). In  some species the body has visible branches; in others it folds in on itself  like intestines. Codium is the favourite food of some sea slugs.</p><p>cod-liver oil Oil obtained primarily from the liver of the Atlantic cod  and related fish. It is principally a mixture of the glycerides (see glycerol)  of many fatty acids, but its minor constituents, the fat-soluble vitamin A  and vitamin D, give it its importance. It was once used to treat and pre�  vent rickets, but the widespread fortification of milk with vitamin D in the  United States and Europe beginning in the 1930s eliminated rickets as a  significant public health problem. It is still used as a remedy for joint pain  caused by arthritis and as a preventive of cardiovascular disease, although  these benefits have not been proven scientifically. It is also used in feeds  for poultry and other animals.</p><p>Cody, William F(rederick) known as Buffalo Bill (b. Feb. 26,  1846, Scott county, Iowa, U.S.�d.</p><p>Jan. 10, 1917, Denver, Colo.) U.S.  buffalo hunter, army scout, and  Indian fighter. He became a rider for  the Pony Express and later served in  the American Civil War. In 1867-68  he hunted buffalo to feed construc�  tion crews for the Union Pacific Rail�  road; he became known as Buffalo  Bill after slaughtering 4,280 head of  buffalo in eight months. He was a  scout for the U.S. 5th Cavalry  (1868-72,1876) as it subdued Indian  resistance. His exploits, including  the scalping of the Cheyenne warrior  Yellow Hair in 1876, were  chronicled by reporters and novel�  ists, who made him a folk hero. He began acting in dramas about the West,  and in 1883 he organized his first Wild West Show, which included stars  such as Annie Oakley and Sitting Bull. The show toured in the U.S. and  abroad to wide acclaim.</p><p>Coe, Sebastian (Newbold) (b. Sept. 29, 1956, London, Eng.) Brit�  ish runner. He won his first major race in 1977. He first ran against his  rival Steve Ovett in 1978, and the two dominated middle-distance racing  in the 1980s. Coe won a total of four Olympic medals (1980, 1984) and  set eight world records. From 1992 to 1997 he served as a Conservative  member in the House of Commons; in 2000 he was elevated to the House  of Lords. Coe also was involved with several athletic organizations.</p><p>coeducation Education of males and females in the same school. A  modern phenomenon, it was adopted earlier and more widely in the U.S.  than in Europe, where tradition proved a greater obstacle to its acceptance.  In the 17th century Quaker and other reformers in Scotland, northern  England, and New England began urging that girls as well as boys be  taught to read the Bible. By the later 18th century girls were being admit�  ted to town schools. By 1900 most U.S. public high schools and some 70%  of colleges and universities were coeducational. Pioneering institutions in  the U.S. included Oberlin College, Cornell University, and the University of  Iowa. In Europe the Universities of Bologna and London and various  Scandinavian institutions were the first to open their doors. Other Euro�  pean countries adopted coeducational policies after 1900, and many com�  munist countries instituted strong coeducational programs.</p><p>coelacanth Vse-l3-,kanth\ Any lobe-finned bony fish of the order Cros-  sopterygii. Members of an extinct suborder are considered to have been</p><p>the ancestors of land vertebrates. Modern coelacanths (genus Latimeria )  are deep-sea fishes with hollow fin spines. They are powerful, heavy�  bodied predators, with highly mobile, limblike fins. They average 5 ft (1.5  m) in length and weigh about 100 lbs (45 kg). Coelacanths appeared about  350 million years ago and were thought to have become extinct 80 mil�  lion years ago until one was caught in 1938 near the southern coast of  Africa in the Indian Ocean. A second species was discovered living near  Indonesia in 1998.</p><p>Coelacanth (Latimeria chalumnae)</p><p>PETER GREEN-ARDEA PHOTOGRAPHICS</p><p>coelenterate See cnidarian</p><p>Coen, Joel and Ethan (respectively b. Nov. 29, 1955, St. Louis Park,  Minn., U.S.; b. Sept. 21, 1958, St. Louis Park) U.S. filmmakers. The  brothers were brought up in Minnesota but moved to New York City to  write scripts for independent films. Their own first film, Blood Simple  (1984), a stylish thriller, was followed by such notable works as Raising  Arizona (1987), Miller�s Crossing (1990), Barton Fink (1991), Fargo  (1996, Academy Award for direction and screen writing), The Big Leb-  owski (1998), and O Brother, Where Art Thou? (2000). With Joel serving  as director and Ethan as producer, they cowrote all their screenplays,  which reflected their offbeat blend of well-paced drama and macabre  humour.</p><p>coenzyme \,ko-'en-zIm\ Any of a number of freely diffusing organic  compounds that function as cofactors with enzymes in promoting a vari�  ety of metabolic reactions. Coenzymes participate in enzyme-mediated  catalysis in stoichiometric (MOLE-for-mole) amounts, are modified during  the reaction, and may require another enzyme-catalyzed reaction to restore  them to their original state. Examples include nicotinamide adenine dinu�  cleotide (NAD), which accepts hydrogen (and gives it up in another reac�  tion), and ATP, which gives up phosphate groups while transferring  chemical energy (and reacquires phosphate in another reaction). Most of  the B vitamins (see vitamin B complex) are coenzymes and are essential in  facilitating the transfer of atoms or groups of atoms between molecules  in the formation of carbohydrates, fats, and proteins. See also metabolism;  STOICHIOMETRY.</p><p>Coercive Acts See Intolerable Acts</p><p>Coetzee \kut-'se\, J(ohn) M(ichael) (b. Feb. 9, 1940, Cape Town,  S.Af.) South African novelist. Coetzee taught English at the University  of Cape Town, translated works from the Dutch, and wrote literary criti�  cism before publishing his first book, Dusklands (1974). He won inter�  national fame with In the Heart of the Country (1977) and Waiting for the  Barbarians (1980), in which he attacked the legacy of colonialism; they  were followed by The Life and Times of Michael K (1983, Booker Prize),  which concerns a man of limited intelligence caught in a civil war; Foe  (1986), a twist on Daniel Defoe�s Robinson Crusoe; the autobiographical  Boyhood (1997); and others. Among his nonfiction works are Giving  Offense: Essays on Censorship (1996) and The Lives of Animals (1999).  In 1999 he became the first writer to win the Booker Prize twice when  he received the award for his novel Disgrace (1999). In 2003 Coetzee  won the Nobel Prize for Literature.</p><p>Coeur \'kcer\, Jacques (b. c. 1395, Bourges, Fr.�d. Nov. 25, 1456,  probably Chios in the Aegean Sea) French merchant and royal official. A  member of the council of King Charles VII, he was put in charge of tax  collection, and was ennobled in 1441. He built a great commercial empire</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>428 I cofactor &#x25BA; cognitivism</p><p>that dealt in salt, silks, and many other commodities, and with his huge  wealth he funded the king�s reconquest of Normandy (1450) and made  loans to many aristocrats. Falsely accused of poisoning the king�s mis�  tress and of dishonest speculation, he was arrested in 1451 but escaped  to Italy. He died while commanding a naval expedition against the Turks.</p><p>cofactor An atom, organic molecule, or molecular group that is neces�  sary for the catalytic activity (see catalysis) of many enzymes. A cofactor  may be tightly bound to the protein portion of an enzyme and thus be an  integral part of its functional structure, or it may be only loosely associ�  ated and free to diffuse away from the enzyme. Cofactors of the integral  kind include metal atoms�such as iron, copper, or magnesium �or mod�  erately sized organic molecules called prosthetic groups; many of the lat�  ter contain a metal atom, often in a coordination complex (see transition  element). Removal of the cofactor from the enzyme�s structure causes loss  of its catalytic activity. Loosely associated cofactors are called coenzymes;  examples include most members of the vitamin B complex. Rather than  directly contributing to the catalytic ability of an enzyme, coenzymes par�  ticipate with the enzyme in the catalytic reaction. Sometimes this distinc�  tion in definition is no longer made, and coenzyme is used in the broader  sense of cofactor.</p><p>coffee Tropical evergreen shrub of the genus Coffea, in the madder family,  or its seeds, called beans; also the beverage made by brewing the roasted  and ground beans with water. Two of the 25 or more species, C. arabica  and C. canephora, supply almost all the world�s coffee. Arabica coffee is  considered to brew a more flavourful and aromatic beverage than Robusta,  the main variety of C. canephora. Arabicas are grown in Central and  South America, the Caribbean, and Indonesia, Robustas mainly in Africa.  The shrub bears bouquets of small white flowers with a jasminelike fra�  grance. The fruit, 0.5-0.75 in. (13-19 mm) long and red when mature, is  called a cherry. Coffee contains large amounts of caffeine, the effects of  which have always been an important element in the drink�s popularity.  Coffee drinking began in 15th-century Arabia. It reached Europe by the  mid 17th century and immediately became hugely popular. Coffee is now  consumed by about one-third of the world�s population.</p><p>coffer In architecture, a square or polygonal ornamental sunken panel  used in a series as decoration for a  ceiling or vault. Coffers were prob�  ably originally formed by wooden  beams crossing one another to pro�  duce a grid. The earliest surviving  examples were made of stone by the  ancient Greeks and Romans. Coffer�  ing was revived in the Renaissance  and was common in Baroque and  Neoclassical architecture.</p><p>cofferdam Watertight enclosure  from which water is pumped to  expose the bed of a body of water in  order to permit the construction of a  pier or other hydraulic work. Coffer�  dams are made by driving metal  sheetpiling (a series of thin, inter�  locking panels) into the bed to form  a watertight fence. Roman engineers  used cofferdams to found the piers of  their arch bridges and aqueducts. See  also CAISSON.</p><p>Coffin, Levi (b. Oct. 28, 1798,</p><p>New Garden, N.C., U.S.�d. Sept. 16, 1877, Cincinnati, Ohio) U.S. abo�  litionist. Despite little formal education, he became a teacher. As a devout  Quaker, he opposed slavery. In 1826 he moved to Newport, Ind., where  he made his home into a depot of the Underground Railroad and used much  of his wealth as a merchant to help the escaping slaves. In 1847 he moved  to Cincinnati, where he opened a store selling goods made only by free  labour. He continued his work with the Underground Railroad until the  outbreak of the American Civil War; he then worked to aid liberated slaves.</p><p>cogeneration In power systems, use of steam for both power genera�  tion and heating. High-temperature, high-pressure steam from a boiler and  superheater first passes through a turbine to produce power. It is exhausted  at a temperature and pressure suitable for heating purposes, instead of  being expanded in the turbine to the lowest possible pressure and then</p><p>discharged to the condenser, which would waste the remaining energy in  the steam. The steam at the higher pressure can provide large amounts of  lower-temperature energy for heating buildings or evaporating brine in a  chemical plant. Considerable overall energy savings can be obtained by  cogeneration. See also steam engine.</p><p>cogito, ergo sum Latin "I think, therefore I am" Dictum coined  in 1637 by Rene Descartes as a first step in demonstrating the attainability  of certain knowledge. It is the only statement to survive the test of his  methodic doubt. The statement is indubitable, Descartes argued, because  even if an all-powerful demon were to try to deceive him into thinking  he exists when he does not, Descartes would have to exist in order to be  deceived. Therefore, whenever he thinks, he exists. Furthermore, Des�  cartes maintained, the statement �I am� (sum) expresses an immediate  intuition, not the conclusion of a process of reasoning, and is thus indu�  bitable.</p><p>cognac \'kon-,yak\ Brandy from the French departments of Charente and  Charente-Maritime. Tracing its origin to the 17th century, cognac (named  for the town of Cognac) is distilled from white wine in special pot stills  (alembics) and aged in Limousin oak. Most cognacs spend from one and  one-half to five years in wood, though rarer varieties may age much  longer.</p><p>cognition Act or process of knowing. Cognition includes every mental  process that may be described as an experience of knowing (including  perceiving, recognizing, conceiving, and reasoning), as distinguished  from an experience of feeling or of willing. Philosophers have long been  interested in the relationship between the knowing mind and external  reality; psychologists took up the study of cognition in the 20th century.  See also cognitive psychology; cognitive science; philosophy of mind.</p><p>cognitive dissonance Mental conflict that occurs when beliefs or  assumptions are contradicted by new information. The concept was intro�  duced by the psychologist Leon Festinger (1919-89) in the late 1950s. He  and later researchers showed that, when confronted with challenging new  information, most people seek to preserve their current understanding of  the world by rejecting, explaining away, or avoiding the new information  or by convincing themselves that no conflict really exists. Cognitive dis�  sonance is nonetheless considered an explanation for attitude change.</p><p>cognitive psychology Branch of psychology devoted to the study of  human cognition, particularly as it affects learning and behaviour. The  field grew out of advances in Gestalt, developmental, and comparative psy�  chology and in computer science, particularly information-processing  research. Cognitive psychology shares many research interests with cog�  nitive science, and some experts classify it as a branch of the latter. Con�  temporary cognitive theory has followed one of two broad approaches:  the developmental approach, derived from the work of Jean Piaget and  concerned with �representational thought� and the construction of men�  tal models (�schemas�) of the world, and the information-processing  approach, which views the human mind as analogous to a sophisticated  computer system.</p><p>cognitive science Interdisciplinary study that attempts to explain the  cognitive processes of humans and some higher animals in terms of the  manipulation of symbols using computational rules. The field draws par�  ticularly on the disciplines of artificial intelligence, psychology (see cog�  nitive psychology), linguistics, neuroscience, and philosophy. Some chief  areas of research in cognitive science have been vision, thinking and rea�  soning, memory, attention, learning, and language processing. Early theo�  ries of cognitive function attempted to explain the evident  compositionality of human thought (thoughts are built up of smaller units  put together in a certain way), as well as its productivity (the process of  putting together a thought from smaller units can be repeated indefinitely  to produce an infinite number of new thoughts), by assuming the exist�  ence of discrete mental representations that can be put together or taken  apart according to rules that are sensitive to the representations� syntac�  tic, or structural, properties. This �language of thought� hypothesis was  later challenged by an approach, variously referred to as connectionism,  parallel-distributed processing, or neural-network modeling, according to  which cognitive processes (such as pattern recognition) consist of adjust�  ments in the activation strengths of neuronlike processing units arranged  in a network.</p><p>cognitivism In metaethics, the thesis that the function of moral sen�  tences (e.g., sentences in which moral terms such as �right,� �wrong,�</p><p>Baroque coffered ceiling of the cupola  of S.

Cognitivists typically try to support their position by seeking out analo�  gies between moral discourse, on the one hand, and scientific and every�  day factual discourse, on the other. Cognitivism is opposed by various  forms of noncognitivism, all of which have in common the denial of the  cognitivist claim that the function of moral sentences is to state or describe  facts.</p><p>Cohan \'ko- l han\ / George M(ichael) (b. July 3, 1878, Providence,  R.I., U.S.�d. Nov. 5, 1942, New  York, N.Y.) U.S. actor, songwriter,  playwright, and producer. Cohan  with his parents and sister performed  in vaudeville as The Four Cohans.</p><p>He began writing for the New York  stage in the early 1900s; his musical  Little Johnny Jones (1904; film,</p><p>1930) included the classics �Give  My Regards to Broadway� and  �Yankee Doodle Dandy.� Among his  later productions were The Gover�  nor�s Son (1901), The Talk of New  York (1907), Broadway Jones  (1912), Seven Keys to Baldpate  (1913), and American Born (1925).</p><p>He later appeared in shows such as  Ah, Wilderness!

His best-  known songs include �You�re a  Grand Old Flag,� �Mary�s a Grand Old Name,� and the famous World  War I recruiting song �Over There,� for which he was awarded a special  Congressional medal in 1940. Cohan was the subject of the film Yankee  Doodle Dandy (1942) and the musical George M! (1968).</p><p>cohen \'ko-3n\ or kohen \ko-'han, ko-'hen\ (Hebrew: �priest�) Jewish  priest descended from Zadok (a descendant of Aaron), priest at the First  Temple of Jerusalem. The biblical priesthood was hereditary and male.  Before King Josiah�s reign (7th century bc), the high priest alone could  enter the Holy of Holies on Yom Kippur. Lower-ranking priests accompa�  nied the army in war or administered the Temple. The priestly class was  strongest during the period of the Second Temple and was curtailed after  its destruction. The rabbinate has replaced the kohanim as authorities on  the Law, but kohanim retain some privileges (except in Reform Judaism).</p><p>coherentism Theory of truth according to which a belief is true just  in case, or to the extent that, it coheres with a system of other beliefs.  Philosophers have differed over the relevant sense of �cohere,� though  most agree that it must be stronger than mere consistency. Among rival  theories of truth, perhaps the oldest is the correspondence theory, which  holds that the truth of a belief consists in its correspondence with inde�  pendently existing facts. In epistemology, coherentism contrasts with  foundationalism, which asserts that ordinary beliefs are justified if they are  inferrable from a set of basic beliefs that are justified immediately or  directly. Coherentism often has been combined with the idealist doctrine  that reality consists of, or is knowable only through, ideas or judgments  (see idealism).</p><p>Cohn, Edwin Joseph (b. Dec. 17, 1892, New York, N.Y, U.S.�d.  Oct. 1, 1953, Boston, Mass.) U.S. biochemist. He received his Ph.D. from  the University of Chicago and taught at Harvard 1922-53. He studied the  components of protein molecules, correlating their structures with their  physical properties and determining basic principles that became the foun�  dation for the further study of proteins. In World War II he headed a team  that devised methods of large-scale production of human plasma fractions  for treatment of the wounded.</p><p>Cohn, Ferdinand (Julius) (b. Jan. 24, 1828, Breslau, Silesia,  Prussia�d. June 25, 1898, Breslau) German naturalist and botanist, con�  sidered one of the founders of bacteriology. He received a Ph.D. from the  University of Berlin at age 19. His early research centred on the single-  celled algae, and his accounts of the life histories of various algae spe�  cies are of permanent value. He was among the first to attempt to arrange  bacteria into genera and species on a systematic basis. Among his most  striking contributions was his discovery of the formation and germination</p><p>of spores in certain bacteria. During his lifetime Cohn was recognized as  the foremost bacteriologist of his day.</p><p>Cohn, Harry (b. July 23, 1891, New York, N.Y., U.S.�d. Feb. 27,  1958, Phoenix, Ariz.) U.S. film producer and cofounder of Columbia Pic�  tures. He worked for a film distributor before cofounding C.B.C. Film  Sales Co. (1920), later named Columbia Pictures Corp. In 1932 he became  president of the company, which he built into a major studio. Though he  came to epitomize the ruthless philistine movie mogul, he was credited  with discovering many stars, including Rita Hayworth, and promoting such  directors as Frank Capra.</p><p>Cohnheim, Julius Friedrich (b. July 20, 1839, Demmin, Prussia�d.  Aug. 15, 1884, Leipzig) German pioneer of experimental pathology.  While assisting Rudolf Virchow, he confirmed that inflammation results  from passage of leukocytes through capillary walls into tissues and that  pus is mainly debris from their disintegration. His induction of tubercu�  losis in a rabbit�s eye led to Robert Koch�s discovery of the tuberculosis  bacillus. His Lectures on General Pathology (2 vol., 1877-80) far out�  lasted contemporary texts. His method of freezing tissue for thin slicing  for microscopic examination is a standard clinical procedure.</p><p>coho or silver salmon Species ( Oncorhynchus kisutch ) of salmon  prized for food and sport that ranges from the Bering Sea to Japan and  the Salinas River of Monterey Bay, Cal. It weighs about 10 lbs (4.5 kg)  and is recognized by the small spots on the back and upper tail-fin lobe.  Young cohos stay in freshwater for about one year before entering North  Pacific waters; they mature in about three years. Some landlocked popu�  lations spend their entire lives in freshwater. Cohos were successfully  transplanted in the 1970s into Lake Michigan as a game fish.</p><p>coin collecting Systematic accumulation and study of coins, tokens,  paper money, and objects of similar form and purpose. The long-held view  that coin collecting began with the Italian Renaissance has been chal�  lenged by growing evidence that the activity is far more venerable. There  exist a variety of literary accounts of collecting from ancient Greek and  Roman sources, and there is tangible archaeological evidence that coins  have been collected at least from the Roman era. Collecting was perhaps  less important during the Middle Ages, but during the 15th-16th centuries  it again became more popular, mostly among European aristocrats. In the  17th century the nature of collecting shifted slowly toward serious  research. As a result, very broad collections were formed, studied, and  catalogued. In the 20th century museums took over the main task of form�  ing large collections of great detail and range. It was also during this time  that a popular market for coins began to develop. Previously only the very  wealthy purchased ancient coins and the number of sources were few.  London became the world�s largest numismatic market, serving the inter�  ests of public collections and private collectors in many lands. The Inter�  net became an important aspect of coin collecting in the late 1990s, both  because it afforded a virtual marketplace that permitted buyers and sellers  from anywhere in the world to trade in coins and for the educational effect  of the many Web sites devoted to the hobby.

Croesus (r. c. 560-546 bc) is generally cred�  ited with issuing the first official government coinage of certified purity  and weight. Counterfeiting was widespread in the Middle Ages. In the  late 15th century, equipment capable of providing coins of reliable weight  and size was developed in Italy. The Industrial Revolution saw further  refinements in coinage techniques. Most of the basic motifs of modern  coinage were introduced in antiquity. In the Greek world, relief imprint�  ing gradually replaced the roughly impressed reverse punch of the Lydi�  ans. Alexander the Great introduced the coin-portrait; these initially  depicted gods or heroes and later living monarchs. Until the end of the  19th century, Chinese coins were cast much like those of the early Greeks;  the square-holed Chinese bronze coins were issued in essentially the same  size and shape for almost 2,500 years.</p><p>coitus See sexual intercourse</p><p>coke Solid residue remaining after certain types of coals are heated to a  high temperature out of contact with air until substantially all components  that easily vaporize have been driven off.

Thereafter the iron industry expanded  rapidly and Britain became the world�s greatest iron producer (see Abra�  ham Darby). The crucible process (1740) resulted in the first reliable steel  made by a melting process. Oven coke (about 1.5-4 in., or 40-100 mm,  in size) is used in blast furnaces to make iron. Smaller quantities of coke  are used in other metallurgical processes (see metallurgy), such as the  manufacture of certain alloys. Large, strong coke, known as foundry coke,  is used in smelting. Smaller sizes of coke (0.6-1.2 in., or 15-30 mm) are  used to heat buildings.</p><p>Coke \kuk\, Sir Edward (b. Feb. 1, 1552, Mileham, Norfolk, Eng.�d.  Sept. 3, 1634, Stoke Poges, Buckinghamshire) British jurist and politi�  cian. He became a lawyer in 1578 and was made solicitor general in 1592.  His advance to the position of attorney general (1594) frustrated his great  rival, Francis Bacon. As attorney general, he conducted several famous  treason trials, prosecuting Robert Devereux, 2nd earl of Essex, and Henry  Wriothesley, 3rd earl of Southampton (1600-01); Sir Walter Raleigh  (1603); and the Gunpowder Plot conspirators (1605). Named chief justice  of the Court of Common Pleas in 1606, Coke earned the ire of James I by  declaring that the king�s proclamation could not change the law (1610).  He upset church leaders by limiting the jurisdiction of ecclesiastical  courts. Appointed chief justice of the King�s Bench by James I (1613),  he remained unswayed; he hinted at scandal in high places and defied a  royal injunction in a case involving ecclesiastical privileges. He was dis�  missed in 1616, partly through Bacon�s efforts. In 1620 he reentered Par�  liament (he had served in 1589), where he denounced interference with  Parliament�s liberties (1621) until he was imprisoned. In 1628 he helped  frame the Petition of Right, a charter of liberties; this defense of the  supremacy of the common law over royal prerogative had a profound  influence on the English law and constitution. On his death his papers  were seized by Charles I. His Reports (1600-15), taken together, are a  monumental compendium of English common law, and his Institutes of  the Lowes of England (4 vol., 1628-44) is an important treatise.</p><p>Cola di Rienzo Vk6-la-de-'ryent-so\ orig. Nicola di Lorenzo (b.</p><p>1313, Rome�d. Oct. 8, 1354, Rome) Italian revolutionary leader. The  son of a tavern keeper, he became a minor Roman official. He plotted a  revolution to restore the glory of ancient Rome, declared himself tribune  in 1347, and began to rule Rome as a dictator. Cola made judicial and  political reforms and prepared for the election of a Roman emperor of  Italy. The nobles rose against him, however, and the pope declared him a  heretic. He fled to the mountains, then traveled to Prague to ask Charles  IV for help. He was arrested (1352) but was absolved of heresy by the  Inquisition. Given the title of senator, he was sent back to Rome in 1354  to help restore papal authority there. He ruled arbitrarily and was soon  killed by a mob. A novel of his life by Edward Bulwer-Lytton was made  into an opera by Richard Wagner.</p><p>Cola dynasty or Chola dynasty South Indian Tamil rulers of  unknown antiquity (before c. ad 200). The dynasty originated in the rich  Cauvery (Kaveri) River valley, and Uraiyur (Tiruchchirappalli) was its  oldest capital. The Cola country stretched from the Vaigai River in the  south to Tondaimandalam in the north. Under Rajendracola Deva I (r.  1014-44), the conquest of Ceylon (Sri Lanka) was completed, the Dec-  can was conquered (c. 1021), and an expedition was sent as far north as  the Ganges (Ganga) River (1023). His successor battled the Calukya  dynasty in the Deccan. The Pandyas conquered the Cola country in 1257,  and the dynasty ended in 1279.

As secretary  of state for the navy from 1668, he  undertook to make France a great  power at sea. He also sought to pro�  mote emigration to Canada and to  enhance France�s power and prestige  in the arts. Though a series of wars  prevented the fulfillment of all his  reforms, he strengthened the monar�  chy and improved the country�s pub�  lic administration and economy,  helping make France the dominant power in Europe.</p><p>Colchester ancient Camulodunum City and borough (pop., 2001:  155,794), southeastern England. In ancient times, the city was the capital  of the powerful pre-Roman ruler Cunobelinus. After his death, the enmity  of his sons toward Rome encouraged the Roman invasion of Britain, and  it became the first Roman colony there, founded by Claudius c. ad 43.  Burned by Boudicca�s warriors c. ad 60, it was reestablished and received  its first charter in 1189. In the 13th century it was a major port. It has a  long history in both cloth making and oyster trading. It is the site of  England�s largest castle keep (built c. 1080), which now houses a museum  of Romano-British antiquities.</p><p>Colchis Vkal-kosX Ancient region on the Black Sea. Now the western  part of the Republic of Georgia, Colchis was in Greek mythology the  home of Medea and the destination of the Argonauts. Historically, it was  colonized by Milesian Greeks with the support of the native Colchians,  whose ethnic composition is unclear. After the 6th century bc it was  nominally controlled by Persia; it passed to Mithradates VI Eupator, the  king of Pontus, in the 1st century bc and later came under Roman rule.</p><p>Cold War Open yet restricted rivalry and hostility that developed after  World War II between the U.S. and the Soviet Union and their respective  allies. The U.S. and Britain, alarmed by the Soviet domination of East�  ern Europe, feared the expansion of Soviet power and communism in  Western Europe and elsewhere. The Soviets were determined to maintain  control of Eastern Europe, in part to safeguard against a possible renewed  threat from Germany. The Cold War (the term was first used by Bernard  Baruch during a congressional debate in 1947) was waged mainly on  political, economic, and propaganda fronts and had only limited recourse  to weapons. It was at its peak in 1948-53 with the Berlin blockade and  airlift, the formation of NATO, the victory of the communists in the Chi�  nese civil war, and the Korean War. Another intense stage occurred in  1958-62 with the Cuban missile crisis, which resulted in a weapons buildup  by both sides. A period of detente in the 1970s was followed by renewed  hostility. The Cold War ended with the collapse of the Soviet Union in</p><empty-line/><p>cold, common Viral infection of the upper and sometimes the lower  respiratory tract. Symptoms, which are relatively mild, include sneezing,  fatigue, sore throat, and stuffy or runny nose (but not fever); they usually  last only a few days. About 200 different strains of virus can produce colds;  they are spread by direct or indirect contact. The cold is the most com�  mon of all illnesses; the average person gets several every year. Incidence  peaks in the fall. Treatment involves rest, adequate fluid intake, and over-  the-counter remedies for the symptoms.

Commercial success, however, came with his singing. His warm, relaxed  voice brought a personal touch to the ballads and light swing in which  he specialized. �Mona Lisa� and �Unforgettable� were among his major  hits of the 1950s.

Coleman began playing the saxo�  phone as a teenager and soon became a working musician in dance bands  and rhythm-and-blues groups. He abandoned harmonic patterns in order  to improvise more directly upon melodic and expressive elements;  because the tonal centres of such music changed at the improviser�s will,  it became known as �free jazz.� His organized collective improvisation in  such recordings as Free Jazz (1960) placed him firmly in the jazz avant-  garde. In the 1970s he began composing orchestral music and also formed  an electric band called Prime Time, with which he was active until the  1990s.</p><p>Coleraine \kol-'ran\ District (pop., 2001: 56,315), Northern Ireland.

Long popular as a pas�  time for children and amateurs, it was first given serious attention as an art  technique by Pablo Picasso and Georges Braque in 1912-13. Many other  20th-century artists produced collages, including Juan Gris, Henri Matisse,  Joseph Cornell, and Max Ernst. In the 1960s collage was employed as a  major form of Pop art, exemplified in the work of Robert Rauschenberg.</p><p>collagen Vka-lo-jonX Any of a class of organic compounds, the most  abundant proteins in the animal kingdom, occurring widely in tendons,  ligaments, dentin (see tooth), cartilage, and other connective tissues. Their  molecules share a triple-helix configuration. Collagens occur as whitish,  inelastic fibres of great tensile strength and low solubility in water. Soluble  when first synthesized (the form used in personal-care preparations), col�  lagen changes to a more stable, insoluble form. Glue made from collagen  in animal hides and skins is a widely used adhesive. Specially treated  forms of collagen are used in medicine and surgery (including lip implants  and other cosmetic surgery), in prostheses, and as sausage casings. Col�  lagen is converted to gelatin by boiling it in water.</p><p>collard Headless form of cabbage (Brassica oleracea, Acephala group),  in the mustard family. It bears the same botanical name as kale, differing  only in that collard leaves are much broader, are not frilled, and resemble  the rosette leaves of head cabbage. The main stem has a rosette of leaves  at the top. Lower leaves commonly are harvested progressively; some�  times the entire young rosette is harvested. The leaves are highly nutri�  tious, rich in minerals and in vitamins A and C.</p><p>collective bargaining Process of negotiation between representa�  tives of workers (usually labour union officials) and management to deter�  mine the conditions of employment. The agreement reached may cover  not only wages but hiring practices, layoffs, promotions, working condi�  tions and hours, and benefit programs. Collective bargaining developed  in England at the end of the 18th century. Although collective bargaining  agreements are common in many countries, they are more scarce in devel�  oping countries that have large pools of surplus labour. Contract negotia�  tions may occur at the national, regional, or local level, depending on the  structure of industry within a country. See also labour union; strike.</p><p>collective farm Russian kolkhoz. In the former Soviet Union, a  cooperative agricultural enterprise operated on state-owned land. Under  the policy of collectivization, which was pursued most intensively by  Joseph Stalin in 1929-33, peasants were forced to give up their individual  farms and join large collective farms. They objected violently and in many  cases slaughtered their livestock and destroyed their equipment before  joining. By 1936 almost all the peasantry had been collectivized, though  millions had also been deported to prison camps. With the breakup of the  Soviet Union in 1990-91, the collective farms began to be privatized.</p><p>collectivism Any of several types of social organization that ascribe  central importance to the groups to which individuals belong (e.g., state,  nation, ethnic group, or social class). It may be contrasted with individu�  alism. Jean-Jacques Rousseau was the first modem philosopher to discuss  it (1762). Karl Marx was its most forceful proponent in the 19th century.  Communism, fascism, and socialism may all be termed collectivist systems.  See also communitarianism; kibbutz; moshav.</p><p>college Institution that offers postsecondary education. The term has  various meanings. In Roman law a collegium was a body of persons asso�  ciated for a common function. The name was used by many medieval  institutions, including guilds. In most universities of the later Middle Ages,  collegium meant an endowed residence hall for university students. The  colleges kept libraries and scientific instruments and offered salaries to  tutors who could prepare students to be examined for degrees. Eventually  few students lived outside colleges, and college teaching eclipsed univer�  sity teaching. In England, secondary schools (e.g., Winchester and Eton)  are sometimes called colleges. Canada also has collegiate schools. In the  U.S., college may refer to a four-year institution of higher education  offering a bachelor�s degree, or to a two-year junior or community college  with a program leading to the associate�s degree. A four-year college usu�  ally emphasizes a liberal arts or general education rather than specialized  technical or vocational preparation. The four-year college may be an inde�  pendent private institution or an undergraduate division of a university.</p><p>collider See particle accelerator</p><p>collie Breed of working dog developed in Great Britain, probably by the  18th century.

Elected as  a member of Sinn Fein to the Irish assembly (1918), he became the Irish  republic�s first minister of home affairs. He was general of the volunteers  and director of intelligence of the Irish Republican Army in the Anglo-Irish  War. In 1921 he signed the controversial Anglo-Irish Treaty, which gave  Ireland dominion status, though with provisions for partition and for an  oath of allegiance to the crown.

For two works, he is remem�  bered as one of the first and best writers of English mystery novels. The  Woman in White (1860), inspired by an actual criminal case, made him  famous. The Moonstone (1868), one of the first English detective novels,  introduced features that became conventions in the genre.</p><p>colloid \'ka-,l6id\ Substance consisting of particles that, although too  tiny to be seen with the unaided eye (typically 1 nanometre to 10 microme�  tres), are substantially larger than atoms and ordinary molecules and that  are dispersed in a continuous phase. Both the dispersed phase and the  continuous phase may be solid, liquid, or gas; examples include suspen�  sions, aerosols, smokes, emulsions, gels, sols, pastes, and foams. Colloids  are often classified as reversible or irreversible, depending on whether  their components can be separated. Dyes, detergents, polymers, proteins, and  many other important substances exhibit colloidal behaviour.</p><p>Collor de Mello Vko-'lor-do-'me-luX, Fernando (Affonso) (b.

Prom�  ising to promote economic growth and combat corruption and inefficiency,  he defeated the leftist Luiz Silva in 1989 to become Brazil�s first popularly  elected president in nearly 30 years. The country�s economic decline,  fueled by a staggering foreign debt and hyperinflation, failed to improve,  and he resigned in 1992 as his trial for corruption was about to begin.</p><p>Colman, Ronald (Charles) (b.

He began a stage and film career in England then moved in 1920 to  the U.S., where he first won notice in The White Sister (1923). A romantic  leading man, he appeared in other silent films such as Beau Geste (1926),  and he easily made the transition to sound movies with his cultivated,  expressive voice. His most notable films include Arrowsmith (1931), A  Tale of Two Cities (1935), Lost Horizon (1937), If I Were King (1938),  Random Harvest (1942), and A Double Life (1947, Academy Award).</p><p>Colmar, Charles Xavier Thomas de See Charles X.

Located on the Rhine  River, it is one of Europe�s key inland ports. First settled by Romans in  the 1st century bc, its commercial importance grew out of its location on  the major European trade routes. In the Middle Ages it also became an  ecclesiastical centre and an important hub of art and learning. Despite its  almost complete destruction in World War II, the city retains some build�  ings and monuments of all periods. Its cathedral, the largest Gothic church  in northern Europe, is its unofficial symbol. Banking has been an impor�  tant industry since the Middle Ages. Eau de cologne, first produced com�  mercially in the 18th century, is still made there. The city is also a major  media centre, with many publishing houses and production facilities for  radio and television. It is famous for its pre-Lenten Carnival.</p><p>Colombia officially Republic of Colombia Country, northwestern  South America. Area: 440,762 sq mi (1,141,568 sq km). Population (2005  est.): 42,954,000. Capital: Bogota. About half the population are mesti�  zos; most of the rest are of European-African, European, or African ances�  try. Language: Spanish (official). Religion: Christianity (predominantly  Roman Catholic). Currency: peso. The topography is dominated by the  Andes Mountains. To the south and east lie vast lowlands, drained by the  Orinoco and Amazon rivers. Colombia�s developing economy is based  primarily on services, agriculture, and manufacturing, coffee being the  principal cash crop. Coca (for the production of cocaine) and opium pop�  pies (for the production of heroin) are grown and trafficked illicitly on a  large scale. Rich in minerals, Colombia is the world�s largest producer of</p><p>emeralds and one of South America�s larg�  est producers of gold. It is a multiparty  loo 260 300km republic with two legislative houses; its  head of state and government is the presi�  dent. Its earliest known inhabitants were  Chibchan-speaking Indians. The Spanish arrived c. 1500 and by 1538 had  conquered the area and made it subject to the Viceroyalty of Peru. After  1740 authority was transferred to the newly created Viceroyalty of New  Granada. Parts of Colombia threw off Spanish jurisdiction in 1810, and  full independence came after Spain�s defeat by revolutionary leader Simon  Bolivar in 1819. Civil war in 1840 slowed development. Conflict between  the Liberal and Conservative parties led to the War of a Thousand Days  (1899-1903). Years of relative peace followed, but hostility erupted again  in 1948; the two parties agreed in 1958 to a plan for alternating govern�  ments. A new constitution was adopted in 1991, but democratic power  remained threatened by civil unrest, which continued into the early 21st  century and at the violent centre of which were powerful drug cartels,  leftist guerrillas, and right-wing paramilitary groups.</p><p>Colombo Nka-'lom-boV City (pop., 2001 prelim.: 642,163), administra�  tive capital of Sri Lanka. Situated on the western coast of the island, it is  a major port with one of the largest artificial harbours in the world. The  area was settled in the 8th century by Arab traders. A fort was established  by the Portuguese in 1518, and the town was occupied by the Dutch in  1656 and the English in 1796. It became the capital of the island in 1815.  Western influence diminished after Sri Lanka gained its independence in  1948. A commercial and industrial centre, Colombo has manufacturing  industries that produce machinery and process food products. It is home  to the University of Colombo (founded 1921).</p><p>Colombo \k6-'lom-bo\, Matteo Realdo (b. 15167, Cremona  [Italy]�d. 1559, Rome) Italian anatomist and surgeon.

Though  the two terms are often used interchangeably, the colon technically  excludes the cecum (a pouch at the beginning of the large intestine), rec�  tum, and anal canal. It runs up the right side of the abdomen (ascending  colon), across it (transverse colon), and down the left side (descending  colon); its last section (sigmoid colon) joins the rectum. It has no diges�  tive function but lubricates waste products, absorbs remaining fluids and  salts, and stores waste products until excretion. Problems involving the  colon include ulcerative colitis, constipation and diarrhea, gas discomfort,  megacolon (enlarged colon), and cancer.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>434 I Colonial National Historical Park &#x25BA; colorimetry</p><p>Colonial National Historical Park Historical reservation, south�  eastern Virginia, U.S. Covering some 15 sq mi (38 sq km) and centred  on a peninsula between the York and James rivers, it was first established  as a national monument in 1930 and includes colonial and Revolutionary  sites. It embraces Cape Henry, Jamestown, and Yorktown and includes the  Colonial Parkway, a 23-mi (37-km) scenic route linking Jamestown, Wil�  liamsburg, and Yorktown.</p><p>colonialism Control by one power over a dependent area or people.  The purposes of colonialism include economic exploitation of the colo�  ny�s natural resources, creation of new markets for the colonizer, and  extension of the colonizer�s way of life beyond its national borders. The  most active practitioners were European countries; in the years 1500-  1900, Europe colonized all of North and South America and Australia,  most of Africa, and much of Asia by sending settlers to populate the land  or by taking control of governments. The first colonies were established  in the Western Hemisphere by the Spanish and Portuguese in the 15th�  16th century. The Dutch colonized Indonesia in the 16th century, and  Britain colonized North America and India in the 17th�18th century. Later  British settlers colonized Australia and New Zealand. Colonization of  Africa only began in earnest in the 1880s, but by 1900 virtually the entire  continent was controlled by Europe. The colonial era ended gradually  after World War II; the only territories still governed as colonies today are  small islands.

See also stoa.</p><p>colony In antiquity, any of the new settlements established in territory  conquered by the Greeks (8th-6th century bc), Alexander the Great (4th  century bc), and the Romans (4th century bc-ad 2nd century). Greek  colonies extended to Italy, Sicily, Spain, the eastern Mediterranean  (including Egypt), and the Black Sea. Alexander pushed even farther into  Central Asia, South Asia, and Egypt. Roman colonization covered much  of the same area and regions south to northern Africa, west to Spain, and  north to Britain and Germany. Reasons for colonizing included expansion  of trade, acquisition of raw materials, resolution of political unrest or  overpopulation, and craving for land and rewards. Colonies retained ties  and loyalty to Rome, though rebelliousness was not uncommon. In Roman  colonies after 177 bc, colonists retained Roman citizenship and could  exercise full political rights. Ancient colonization spread Hellenic and  Roman culture to the far reaches of the empires, often assimilating local  populations, some of whom acquired Roman citizenship.</p><p>colony In zoology, a group of organisms of one species that live and  interact closely with each other in an organized fashion. A colony differs  from an aggregation, in which the group has no cooperative or organized  function. Colonies of social insects (e.g., ants, bees) usually include castes  with different responsibilities. Many birds form temporary breeding colo�  nies, in some cases to stimulate reproductive activities, in others to make  the best use of a limited breeding habitat and to coordinate efforts in pro�  tecting nests from predators. Certain mammals that live in close groups  are said to be colonial, though they lack cooperative activities and each  maintains a territory.</p><p>Colophon \'ka-l3-,fan\ Ancient Ionian Greek city, western Anatolia.  Located 15 mi (25 km) northwest of the ancient city of Ephesus, it was a  flourishing commercial city in the 8th-5th centuries bc, famous for its  cavalry, its luxury, and its production of rosin. A member of the Delian  League, during the Peloponnesian War it was controlled first by the Per�  sian Achaemenian dynasty and then by Athens, and it was conquered in  302 bc by Macedonia under Alexander the Great. Only a few foundations  of the old walled city are now visible.</p><p>Colorado Group of Indian people of Ecuador�s Pacific coast. In the  tropical lowlands where the Colorado traditionally have lived, they and  the neighbouring Cayapas are the last remaining aboriginal groups.

Lying astride the  Rocky Mountains, the state has three physiographic regions: the plains, a  semiarid segment of eastern Colorado; the Colorado Piedmont in the cen�  tral part of the state, where most of the population lives; and the south�  ern Rocky Mountains and mesas of western Colorado. Its large urban  population has grown faster than the national average. Its original inhab�  itants were Plains and Great Basin Indians, including the Arapaho, Chey�  enne, and Ute. The area was claimed by Spain in 1706 but later passed in  large part to France. Eastern Colorado was part of the Louisiana Purchase  in 1803; the remainder stayed in Spanish and, after independence, Mexi�  can hands until 1848. Gold was discovered in 1859 and touched off a  population boom. Organized as the territory of Colorado in 1861, it  achieved U.S. statehood in 1876. Agriculture, cattle production, and min�  ing, as well as manufacturing, are important to the economy. Government  military installations and service industries have become prominent, and  tourism is a major source of the state�s income (see Aspen; Boulder; Vail).</p><p>Colorado National Monument Natural area, western Colorado,  U.S. Established in 1911, the 32-sq-mi (83-sq-km) scenic area is known  for its colourful, wind-eroded sandstone formations, towering monoliths,  and steep-walled canyons. Petrified logs and dinosaur fossils have been  found in the area. Rim Rock Drive skirts the canyon walls, which rise  more than 6,500 ft (1,980 m).</p><p>Colorado potato beetle or potato bug Leaf beetle (Leptinotarsa  decemlineata, family Chrysomelidae) native to western North America.  It began feeding on the leaves of cultivated potatoes when the plants were  introduced into western North America, and by 1874 it had become an  important and widespread pest. It has a hemispherical body, about 0.4 in.  (10 mm) long, and is orange-red or yellow, with black stripes on the wing  covers. Depending on climate, potato beetles may produce one to three  generations each year.</p><p>Colorado River River, south-central Argentina. Its major headstreams,  the Grande and Barrancas rivers, flow southward from the Andes Moun�  tains and meet to form the Colorado near the Chilean border. It flows  southeastward across northern Patagonia and the southern Pampas. Its  lower course splits into two arms that flow into the Atlantic Ocean south  of Bahia Blanca. Its total length is about 530 mi (850 km).</p><p>Colorado River River, western Texas, U.S. It flows southeast 862 mi  (1,387 km) through prairie, hill, and canyon country past Austin and across  the coastal plain to enter Matagorda Bay.

Rising in the Rocky Mountains  of Colorado, U.S., it flows west and south 1,450 mi (2,330 km) to empty  into the Gulf of California in northwestern Mexico. It drains a vast sector  of the North American continent, about 246,000 sq mi (637,000 sq km).  No other river in the world has cut so many deep trenches, of which the  Grand Canyon is the largest and most spectacular. It is important for  hydroelectric power and irrigation; more than 20 dams, including Hoover  Dam, have been built on the Colorado River and its tributaries.</p><p>Colorado Springs City (pop., 2000: 360,890), central Colorado, U.S.  Standing on a mesa near the eastern base of Pikes Peak, it was founded in  1871 as Fountain Colony and later renamed for nearby mineral springs.  Growth followed the Cripple Creek gold strikes in the 1890s. Military  installations gave further impetus to development: it is home to the North  American Aerospace Defense Command (NORAD) and the U.S. Space  Command, headquartered at Peterson Air Force Base (established 1942);  Fort Carson (1942); and the U.S. Air Force Academy (1958).

Unlike ear�  lier amphitheaters, which were  nearly all dug into hillsides for extra  support, the Colosseum is a free�  standing oval colonnaded structure  of stone and concrete. It was the  scene of combats between gladiators,  contests of men with animals, and  even mock naval engagements. The  Colosseum was damaged by lightning and earthquakes in medieval times  and, even more severely, by vandals. A restoration project was undertaken  in the 1990s, and in 2000 the Colosseum staged a series of plays that  marked the first time in more than 1,500 years that live performances had  been held there.</p><p>Colossus of Rhodes See Colossus of Rhodes</p><p>colostomy \k9-Tas-t3-me\ Surgical formation of an artificial anus by  making an opening from the colon through the abdominal wall.

A sigmoid colostomy, the most  common type of permanent colostomy, requires no appliances (though a  light pouch is sometimes worn for reassurance) and allows a normal life  except for the route of fecal excretion. See also ostomy.</p><p>colour Aspect of any object that may be described in terms of hue,  brightness, and saturation. It is associated with the visible wavelengths of  electromagnetic radiation, which stimulate the sensor cells of the eye. Red  light has the longest wavelengths, while blue has the shortest, with other  colours such as orange, yellow, and green between. Hue refers to domi�  nant wavelengths. Brightness refers to the intensity or degree of shading.  Saturation pertains to purity, or the amount of white light mixed with a  hue. The colours red, yellow, and blue, known as primary colours, can be  combined in varying proportions to produce all other colours. Primary  colours combined in equal proportions produce secondary colours. Two  colours that combine to form white light are said to be complementary.</p><p>colour blindness Inability to distinguish one or more colours. The  human retina contains three types of cone cells that absorb light in dif�  ferent parts of the spectrum. Absence of these types causes colour blind�  ness to red, green, and blue. Colour blindness is a sex-linked recessive  trait (see recessiveness) 20 times more common in men than in women.</p><p>colour index In igneous petrology, the sum of the volume percentages  of the coloured, or dark, minerals in the rock.

Many garden hybrids are cul�  tivated for their showy flowers.</p><p>Columbus, Christopher Italian Cristoforo Colombo Spanish  Cristobal Colon (b. between Aug. 26 and Oct. 317, 1451, Genoa�d.  May 20, 1506, Valladolid, Spain) Genoese navigator and explorer whose  transatlantic voyages opened the way for European exploration, exploi�  tation, and colonization of the Americas. He began his career as a young  seaman in the Portuguese merchant marine. In 1492 he obtained the spon�  sorship of the Spanish monarchs Ferdinand II and Isabella I for an attempt  to reach Asia by sailing westward over what was presumed to be open</p><p>sea. On his first voyage he set sail in August 1492 with three ships�the  Santa Maria, the Nina, and the Pinta �and land was sighted in the Baha�  mas on October 12. He sailed along the northern coast of Hispaniola and  returned to Spain in 1493. He made a second voyage (1493-96) with at  least 17 ships and founded La Isabela (in what is now the Dominican  Republic), the first European town in the New World. This voyage also  began Spain�s effort to promote Christian evangelization. On his third  voyage (1498-1500) he reached South America and the Orinoco River  delta. Allegations of his poor administration led to his being returned to  Spain in chains. On his fourth voyage (1502-04) he returned to South  America and sailed along the coasts of present-day Honduras and Panama.  He was unable to attain his goals of nobility and great wealth. His char�  acter and achievements have long been debated, but scholars generally  agree that he was an intrepid and brilliant navigator.</p><p>Columbus City (pop., 2000: 186,291), western Georgia, U.S. Located  on the Chattahoochee River, it was founded in 1828 and by 1840 had  become a leading inland cotton port with a thriving textile industry. Dur�  ing the American Civil War it was a major supply city for the Confederacy  and the site of the last battle east of the Mississippi. Now highly indus�  trialized, Columbus is one of the South�s largest textile centres. It is home  to the National Civil War Naval Museum. Fort Benning (established 1918)  is nearby.</p><p>Columbus City (pop., 2000: 711,470), capital of Ohio, U.S. Located at  the junction of the Scioto and Olentangy rivers, the city was planned in  1812 as a political centre and sited opposite the original 1797 settlement  of Franklinton; the state government moved to the city in 1816. The arrival  of roads, canals, and rail in the mid 19th century led to significant growth,  and by 1900 Columbus had emerged as an important transportation and  commercial centre. It is Ohio�s largest city, and its economy is supported  by industry, governmental agencies, and numerous educational and  research institutions, including the Ohio State University.</p><p>Columbus Platform In Reform Judaism, a declaration issued by a con�  ference of U.S. Reform rabbis meeting in Columbus, Ohio, in 1937.

It is usually associated with  cerebral injury of metabolic or physical origin. Simple concussions cause  short losses of consciousness. Coma from lack of oxygen may last sev�  eral weeks and is often fatal. Coma caused by stroke can be sudden, while  that caused by metabolic abnormalities (as in diabetes melutus) or cerebral  tumours comes on gradually. Treatment depends on the cause.</p><p>Comana \k3-'ma-n9\ Ancient city in Cappadocia, eastern Anatolia.  Located on the Seyhan River in the Taurus Mountains, it was the centre  of the cult of the mother goddess Ma-Enyo and the site of lavish celebra�  tions. It was governed by a chief priest, usually a member of the reign�  ing Cappadocian family, who ranked next to the king. A Roman colony  in the 3rd century ad, it lay on the chief military road to the empire�s  eastern frontier.</p><p>Comanche \k9-'man-che\ Nomadic North American Indian group of  southwest Oklahoma, Texas, California, and New Mexico, U.S. The name  Comanche is derived from a Ute word meaning �anyone who wants to  fight me all the time�; the people call themselves Numunuh (meaning</p><p>Doric columns on the Greek temple at  Segesta, Sicily, c. 424-416 bc</p><p>SCALA/ART RESOURCE, NY</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Comaneci &#x25BA; comic book i 437</p><p>�The People�). Their language is of Uto-Aztecan stock. An offshoot of  the Shoshone, they were organized into about 12 autonomous bands, local  groups that lacked the lineages, clans, military societies, and tribal gov�  ernment of most other Plains Indians. They roamed the southern Great  Plains in the 18th and 19th century. Their staple food was buffalo meat.  Their highly skilled horsemen set the pattern of equestrian nomadism on  the Plains. In 1864 Col. Kit Carson led U.S. forces in an unsuccessful  campaign against them. Treaties were signed in 1865 and 1867, but the  federal government failed to keep whites off the land promised to them,  which led to violent conflicts. In later years Comanche Code-Talkers, like  other Native American Code-Talkers, played a notable role during both  world wars. Some 10,000 people claimed sole Comanche descent in the  2000 U.S. census.</p><p>Comaneci \,ko-m9- , ne-che\ / Nadia (b. Nov. 12, 1961, Gheorghe  Gheorghiu-Dej, Rom.) Romanian-born gymnast.

In the  1976 Olympic Games, the first in which a perfect score of 10 was ever  awarded in an Olympic gymnastic event, she received an astounding  seven perfect scores and won the gold medals for the balance beam,  uneven parallel bars, and all-around competitions. In the 1980 Olympics  she won gold medals for the beam and the floor exercises.

As premier (1902-05), he presided  over the separation of church and state in the wake of the Alfred Dreyfus  affair. He agreed to laws exiling almost all religious orders from France  and dismantling major aspects of the church�s public functions, especially  in education. Admired by many republicans, he later served as minister  without portfolio (1915), despite his advanced age.</p><p>combination See permutations and combinations</p><p>Combination Acts British acts of 1799 and 1800 that outlawed trade  unions. The laws made it illegal for any workingman to combine with  another to gain an increase in wages or a decrease in hours, to solicit any�  one else to leave work, or to object to working with any other workman.  They were repealed in 1824 through the efforts of the radical reformer  Francis Place (1771-1854).</p><p>combinatorics V.kam-bo-no-'tor-iksV Branch of mathematics concerned  with the selection, arrangement, and combination of objects chosen from  a finite set. The number of possible bridge hands is a simple example;  more complex problems include scheduling classes in classrooms at a  large university and designing a routing system for telephone signals. No  standard algebraic procedures apply to all combinatorial problems; a sepa�  rate logical analysis may be required for each problem. Combinatorics  has its roots in antiquity, but new uses in computer science and systems  management have increased its importance in recent years. See also per�  mutations AND COMBINATIONS.</p><p>combine harvester Farm machine used, mainly in developed coun�  tries, to harvest wheat and often other cereals. The mechanical ancestor  of today�s large combines was Cyrus H. McCormick�s reaper, introduced  in 1831. Threshing machines were powered first by men or animals, often  using treadmills, later by steam engines and internal-combustion engines.  The modern combine harvester, originally introduced in California c.  1875, came into wide use in the U.S. in the 1920s and �30s and in Brit�  ain in the 1940s. The self-propelled combine was introduced in 1940. The  combine cuts the standing grain, threshes out the grain from the straw and  chaff, cleans the grain, and empties it into bags or grain-storage facilities.  It has greatly reduced harvesting time and labour; whereas in 1829 har�  vesting an acre of wheat required 14 man-hours, the modem combine  requires less than 30 minutes.</p><p>combining weight See equivalent weight</p><p>Comden, Betty orig.

The world�s longest-established national theatre, it was founded in 1680  by the merger of two theatrical companies in Paris, one of them the troupe  that had worked under Moliere. The French Revolution divided the com�  pany�s loyalties, and the revolution�s supporters, led by Francois-Joseph  Talma, moved to the theatre�s present home in 1791. The company was  reconstituted in 1803. Under its rules of organization, established by  Napoleon in 1812, its members share responsibilities and profits. Its illus�  trious actors have included Sarah Bernhardt and Jean- Louis Barrault. The  theatre is known for productions of the French classics, though it also  performs contemporary plays.</p><p>comedy Genre of dramatic literature that deals with the light and amus�  ing or with the serious and profound in a light, familiar, or satirical man�  ner. Comedy can be traced to revels associated with worship in Greece in  the 5th century bc. Aristophanes, Menander, Terence, and Plautus produced  comedies in classical literature. It reappeared in the late Middle Ages,  when the term was used to mean simply a story with a happy ending (e.g.,  Dante�s Divine Comedy ), the same meaning it has in novels of the last  three centuries (e.g., the fiction of Jane Austen). Compare tragedy.</p><p>comedy of manners Witty, ironic form of drama that satirizes the  manners and fashions of a particular social class or set. Comedies of man�  ners were usually written by sophisticated authors for members of their  own social class, and they typically are concerned with social usage and  the ability or inability of certain characters to meet social standards, which  are often exacting but morally trivial. The plot, usually concerning an  illicit love affair or other scandalous matter, is subordinate to the play�s  brittle atmosphere, witty dialogue, and pungent commentary on human  foibles. Its notable exponents include William Congreve, Oliver Goldsmith,  Richard Brinsley Sheridan, Oscar Wilde, and Noel Coward.</p><p>Comenius \k3-'me-ne-3s\, John Amos Czech Jan Amos Komen-</p><p>sky (b.

He favoured  the learning of Latin to facilitate the study of European culture but empha�  sized learning about things rather than about grammar per se. His Janua  Linguarum Reserata (1631), a textbook that described useful facts about  the world in both Latin and Czech, revolutionized Latin teaching and was  translated into 16 languages. He also produced one of the first illustrated  schoolbooks, Orbis Sensualium Pictus (1658).</p><p>comet Any of a class of small icy objects orbiting the Sun and devel�  oping diffuse gaseous envelopes and often long glowing tails when near  the Sun. They are distinguished from other objects in the solar system by  their composition, hazy appearance, and elongated orbits. Most comets  originate in the Oort cloud or in the Kuiper belt. Other bodies� gravity can  alter their orbits, causing them to pass close to the Sun. Short-period  comets return in 200 years or less, others in thousands of years or not at  all. A comet typically consists of a small, irregular nucleus, often  described as a �dirty snowball,� with dust and other materials frozen in  water mixed with volatile compounds. When one nears the Sun, the heat  vaporizes its surface, releasing gases and dust particles, which form a  cloud (coma) around the nucleus. Material in the coma may be pushed  away from the Sun by its radiation and the solar wind, forming one or  more tails. Meteor showers occur when Earth passes through dust left by  the passage of a comet.</p><p>comfrey Vkom-freV Any herb of the Eurasian genus Symphytum (bor�  age family). Best known is the medicinal common comfrey (S. officinale),  used to treat wounds and as a source of a gum used to treat wool. Tradi�  tionally it was also taken internally for various complaints. Organic farm�  ers use it to deter slugs and as a green manure. The coiled sprays of bell�  like, hanging comfrey blooms are usually pollinated by bees. Common  comfrey is about 3 ft (90 cm) tall, with winged, hairy stems and blue,  purplish, or yellow flowers.</p><p>comic book Bound collection of comic strips, usually in chronological  sequence, typically telling a single story or a series of different stories.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>438 i comic strip &#x25BA; commode</p><p>The first true comic books were marketed in 1933 as giveaway advertis�  ing premiums. By 1935 reprints of newspaper strips and books with origi�  nal stories were selling in large quantities. During World War II comics  dealing with war and crime found many readers among soldiers stationed  abroad, and in the 1950s comic books were blamed for juvenile delin�  quency. Though the industry responded with self-censorship, some adven�  ture strips continued to be criticized. In the 1960s comic books satirizing  the cultural underworld became popular, especially among college stu�  dents, and comic books have been used to deal with serious subjects (e.g.,  Art Spiegelman�s Maus books, about the Holocaust). Japanese comic  books (manga), with their great variation in content and affect, have  achieved wide popularity. Today comic ��zines� represent a thriving sub�  culture.</p><p>comic strip Series of drawings that read as a narrative, arranged  together on the page of a newspaper, magazine, or book. In the 1890s  several U.S. newspapers featured weekly drawings that were funny, but  without indicated speech. In 1897 Rudolph Dirks�s Katzenjammer Kids,  in the New York Journal, featured humorous strips containing words pre�  sumably spoken by the characters. Soon speeches in balloons appeared  in other cartoons, arranged in a series to form a strip. The comic strip  arrived at its maturity in 1907 with Bud Fisher�s Mutt and Jeff, which  appeared daily in the San Francisco Chronicle. Important later comic-  strip artists include George Herriman, Al Capp, Walt Kelly, and Charles  Schulz.

Its  original members were the Communist Parties of the Soviet Union, Bul�  garia, Czechoslovakia, Hungary, Poland, Romania, Yugoslavia, France,  and Italy, but Yugoslavia was expelled in 1948. The Cominform�s activi�  ties consisted mainly of publishing propaganda to encourage international  communist solidarity. It was dissolved by Soviet initiative in 1956 as part  of a Soviet program of reconciliation with Yugoslavia.</p><p>Comintern or Communist International or Third Interna�  tional Association of national communist parties founded in 1919.  Vladimir Ilich Lenin called the first congress of the Comintern to undermine  efforts to revive the Second International. To join, parties were required  to model their structure in conformity with the Soviet pattern and to expel  moderate socialists and pacifists. Though the Comintern�s stated purpose  was the promotion of world revolution, it functioned chiefly as an organ  of Soviet control over the international communist movement. In 1943,  during World War II, Joseph Stalin dissolved the Comintern to allay fears  of communist subversion among his allies.</p><p>Comitia Centuriata Nko-'mish-o-.sen-.tur-e-'a-toV Ancient Roman  military assembly, instituted c. 450 bc. It decided on war and peace, passed  laws, elected consuls, praetors, and censors, and considered appeals of  capital convictions. Unlike the older patrician Comitia Curiata, it included  plebeians as well as patricians, assigned to classes and centuriae (centuries,  or groups of 100) by wealth and the equipment they could provide for  military duty. Voting started with the wealthier centuries, whose votes  outweighed those of the poorer.</p><p>command economy Economic system in which the means of produc�  tion are publicly owned and economic activity is controlled by a central  authority. Central planners determine the assortment of goods to be pro�  duced, allocate raw materials, fix quotas for each enterprise, and set prices.  Most communist countries have had command economies; capitalist  countries may also adopt such a system during national emergencies (e.g.,  wartime) in order to mobilize resources quickly. See also capitalism; com�  munism.</p><p>commando In British military forces, a unit consisting of marines and  soldiers organized for rapid deployment and trained to conduct special  operations. The commando originated with the Boers in South Africa,  where it was the administrative and tactical unit �commandeered� by law.  In World War II the British adopted the term for a new specially trained  amphibious raiding force. Modern commandos are units of the Royal  Marines with support troops from the British Army; by extension a mem�  ber of such a unit is also called a commando and is entitled to wear a  green beret.</p><p>commedia dell'arte \k6m-'mad-ya-del-Tar-ta\ Italian theatrical form  that flourished throughout Europe in the 16th�18th centuries.

The style emphasized improvisation within a frame�  work of conventionalized masks and stock situations. It was acted by pro�  fessional companies using vernacular dialects and plenty of comic action;  the first known commedia dell�arte troupe was formed in 1545. Outside  Italy it had its greatest success in France as the Comedie-Italienne; in  England, it was adapted in the harlequinade and the Punch-and-Judy show  (see Punch).

Early commercial banks were limited to  accepting deposits of money or valuables for safekeeping and verifying  coinage or exchanging one jurisdiction�s coins for another�s. By the 17th  century most of the essentials of modern banking, including foreign  exchange, the payment of interest, and the granting of loans, were in place.  It became common for individuals and firms to exchange funds through  bankers with a written draft, the precursor to the modern check. Because  a commercial bank is required to hold only a fraction of its deposits as  cash reserves, it can use some of the money deposited by its customers  to extend loans. Commercial banks also offer a range of other services,  including savings accounts, safe-deposit boxes, and trust services.

It received stimulus from the voyages of  exploration undertaken by England, Spain, and other nations to Africa,  Asia, and the New World. Among the features associated with it were a  surge in overseas trade, the appearance of the chartered company, accep�  tance of the principles of mercantilism, the creation of a money economy,  increased economic specialization, and the establishment of such new  institutions as the state bank, the bourse, and the futures market.

The group was  founded in 1992 and consists largely of academics and lower-level Mus�  lim clergy. It considers itself a pressure group for peaceful reform and for  improving human rights in Saudi Arabia but also agitates against what it  perceives as the political corruption of the Saudi government and ruling  family. Its leader is a former physics professor, Muhammad ibn  al-Masa c arI. In 1994, after experiencing government repression, the group  moved its headquarters to London. Despite its claim to advocate peace�  ful change, the group has been accused of aiding Islamic militants seek�  ing to overthrow the Saudi government.</p><p>Committee of Public Safety Political body of the French Revolution  that controlled France during the Reign of Terror. It was set up in April  1793 to defend France against its enemies, foreign and domestic. At first  it was dominated by Georges Danton and his followers, but they were  soon replaced by the radical Jacobins, including Maximilien Robespierre.  Harsh measures were taken against alleged enemies of the Revolution,  the economy was placed on a wartime basis, and mass conscription was  undertaken. Dissension within the committee contributed to the downfall  of Robespierre in July 1794, after which it declined in importance.</p><p>Committees of Correspondence Groups appointed by the legis�  latures of all 13 American colonies to provide a means of intercolonial  communication. The first standing group was formed by Samuel Adams in  Boston (1772), and within three months 80 others were formed in Mas�  sachusetts. In 1773 Virginia organized a committee with 11 members,  including Thomas Jefferson and Patrick Henry. The committees were instru�  mental in promoting colonial unity and in summoning the First Conti�  nental Congress in 1774.</p><p>commode Piece of furniture resembling the English chest of drawers,  used in France from the late 17th century.

Because  it alone has the power to levy taxes and allocate expenditures, it is Brit�  ain�s chief legislative authority. It originated in the late 13th century, when  landholders and other property owners began sending representatives to  Parliament to present grievances and petitions to the king and to accept  commitments to the payment of taxes. It was the less powerful house until  1911, when the Reform Bill of that year gave it the power to override the  House of Lords.

It stems from Claude E. Shannon�s mathematical methods for  measuring the degree of order (nonrandomness) in a signal, which drew  largely on probability theory and stochastic processes and led to techniques  for determining a source�s rate of information production, a channel�s  capacity to handle information, and the average amount of information in  a given type of message. Crucial to the design of communications sys�  tems, these techniques have important applications in linguistics, psychol�  ogy, and even literary theory.</p><p>communications satellite Earth-orbiting system capable of receiv�  ing a signal (e.g., data, voice, TV) and relaying it back to the ground.  Communications satellites have been a significant part of domestic and  global communications since the 1970s.

The theory was principally the work of Karl Marx and  Friedrich Engels. Their "Communist Manifesto" (1848) further specified a  �dictatorship of the proletariat,� a transitional stage Marx called socialism;  communism was the final stage in which not only class division but even  the organized state�seen by Marx as inevitably an instrument of  oppression�would be transcended (see Marxism). That distinction was  soon lost, and �communist� began to apply to a specific party rather than  a final goal. Vladimir Iuch Lenin maintained that the proletariat needed pro�  fessional revolutionaries to guide it (see Leninism). Joseph Stalin�s version  of communism (see Stalinism) was synonymous to many with totalitari�  anism. Mao Zedong mobilized peasants rather than an urban proletariat in  China�s communist revolution (see Maoism). European communism (see  Eurocommunism) lost most of its following with the collapse of the Soviet  Union (1991).

It  argued that industrialization had exacerbated the divide between the capi�  talist ruling class and the proletariat, which had become impoverished,  and called on the proletariat to overthrow the capitalists, abolish private  property, and take over the means of production. It predicted an eventual  classless society and the gradual elimination of the need for a state. It  ends by stating, �The proletarians have nothing to lose but their chains.  They have a world to win. Workingmen of all countries, unite.�</p><p>Communist Party Political party organized to facilitate the transition  of society from capitalism through socialism to communism. Russia was the  first country in which communists came to power (1917). In 1918 the  Bolshevik party was renamed the All-Russian Communist Party; the name  was taken to distinguish its members from the socialists of the Second  International who had supported capitalist governments during World War  I. Its basic unit was the workers� council (soviet), above which were dis�  trict, city, regional, and republic committees. At the top was the party  congress, which met only every few years; the delegates elected the mem�  bers of the Central Committee, who in turn elected the members of the  Politburo and the Secretariat, though those organizations were actually  largely self-perpetuating. The Soviet Union dominated communist parties  worldwide through World War II. Yugoslavia challenged that hegemony  in 1948 and China went its own way in the 1950s and �60s. Communist  parties have survived the demise of the Soviet Union (1991), but with  reduced political influence. Cuba�s party remains in control, as does a  hereditary communist party in North Korea.</p><p>Communist Party of the Soviet Union (CPSU) Major political  party of Russia and the Soviet Union from the Russian Revolution of 1917  to 1991. It arose from the Bolshevik wing of the Russian Social-Democratic  Workers' Party. From 1918 through the 1980s it was a monolithic,  monopolistic ruling party that dominated the Soviet Union�s political,  economic, social, and cultural life. The constitution and other legal docu�  ments that supposedly regulated the government were actually subordi�  nate to the CPSU, which also dominated the Comintern and the Cominform.  Mikhail Gorbachev�s efforts to reform the country�s economy and politi�  cal structure weakened the party, and in 1990 it voted to surrender its  constitutionally guaranteed monopoly of power. The Soviet Union�s dis�  solution in 1991 marked the party�s formal demise.</p><p>communitarianism Political and social philosophy that emphasizes  the importance of community in the functioning of political life, in the  analysis and evaluation of political institutions, and in understanding  human identity and well-being. It was developed in the 1980s and �90s  in explicit opposition to the theoretical liberalism of thinkers such as John  Rawls. According to communitarians, liberalism relies on a conception of  the individual that is unrealistically atomistic and abstract; it also places  too much importance on individual values such as freedom and autonomy.  Its chief representatives include Amitai Etzioni, Michael Sandel, and  Charles Taylor.

Comoros comprises a group of islands  between Madagascar and the eastern African mainland that includes  Njazidja (Grande Comore), Mwali (Moheli), and Nzwani (Anjouan) but  excludes Mayotte. They are generally rocky, with shallow soils and poor  harbours, though Mwali, the smallest, has fertile valleys and forested hill�  sides. Mount Karthala, an active volcano, is the highest point, at 7,746 ft  (2,361 m). The climate is tropical. One of the world�s poorest nations,  Comoros has an economy based on subsistence agriculture. It is an Islamic  republic with one legislative house. The head of state and government is  the president, assisted by vice presidents. Known to European navigators  since the 16th century, the dominant influence on the islands was then and  for long afterward Arab. In 1843 France officially took possession of  Mayotte and in 1886 placed the other three islands under protection. Sub�</p><p>ordinated to Madagascar in 1912, the Comoros became an overseas ter�  ritory of France in 1947. In 1961 they were granted internal autonomy.  In 1974 majorities on three of the islands voted for independence, which  was declared in 1975. The following decade saw several coup attempts,  culminating in the assassination of the president in 1989. French inter�  vention permitted multiparty elections in 1990, but the country remained  in a state of chronic instability, including secessionist movements on  Nzwani and Mwali. In 1999 the army took control of the government and  negotiated a constitution that took effect in 2002.</p><p>compact disc (CD) Molded plastic disc containing digital data that is  scanned by a laser beam for the reproduction of recorded sound or other  information. Since its commercial introduction in 1982, the audio CD has  become the dominant format for high-fidelity recorded music. Digital  audio data can be converted to analog form to reproduce the original audio  signal (see digital-to-analog conversion). Coinvented by Philips Electron�  ics and Sony Corp. in 1980, the compact disc has expanded beyond audio  recordings into other storage-and-distribution uses, notably for comput�  ers (CD-ROM) and entertainment systems (videodisc and DVD). An audio  CD can store just over an hour of music. A CD-ROM can contain up to  680 megabytes of computer data.

The discipline pays particu�  lar attention to the psychological nature of humans in comparison with  other animals. It began to emerge in the late 19th century and grew rap�  idly in the 20th century, involving experimental studies on human and  animal brain function, learning, and motivation. Well-known studies have  included those of Ivan Pavlov on conditioning in laboratory dogs, those of  Harry Harlow (1905-81) on the effects of social deprivation in monkeys,  and those of various researchers on language abilities in apes.</p><p>comparator Vkom-'par-o-torV Instrument for comparing something  with a similar thing or with a standard measure, in particular to measure  small displacements in mechanical devices.

Compasses may operate on magnetic or gyro�  scopic (see gyroscope) principles or by determining the direction of the  Sun or a star. The oldest and most familiar type is the magnetic compass,  used in different forms in aircraft, ships, and land vehicles and by sur�  veyors. Magnetic compasses work as they do because the Earth itself is  a magnet with a north-south field (see geomagnetic field) that causes freely  moving magnets to align themselves with the field.</p><p>compatibilism Thesis that free will, in the sense required for moral  responsibility, is consistent with universal causal determinism. It is impor�  tant to distinguish the question of the logical consistency of belief in uni�  versal causal determinism with belief in free will from the question  whether the thesis of free will (or that of causal determinism) is true.  Compatibilists need not assert (though many have) the reality both of free  will and of causal determinism. Among incompatibilists, some maintain  the existence of free will and accordingly deny universal causal deter�  minism, while others uphold universal causal determinism and deny the  existence of free will.

In proof  theory, a formal system is said to be syntactically complete if and only if  every closed sentence in the system is such that either it or its negation  is provable in the system. In model theory, a formal system is said to be  semantically complete if and only if every theorem of the system is prov�  able in the system.</p><p>complex number Any number consisting of both real numbers and  imaginary numbers. It has the form a + bi, where a and b are real numbers  and i = V�T; a is called the real part and bi the imaginary part. Because  a or b can equal 0, any real or imaginary number is also a complex num�  ber. Invented as an extension of the real numbers so that certain algebraic  equations such as x 2 + 1 = 0 would have solutions, the complex numbers  form an algebraic field, meaning that they obey the commutative law and  the associative law (with respect to addition and multiplication), as well  as certain other rules in much the same way real numbers do (see field  theory).</p><p>complex variable In mathematics, a variable that can take on the value  of a complex number. In basic algebra, the variables x and y generally stand  for values of real numbers. The algebra of complex numbers (complex  analysis) uses the complex variable z to represent a number of the form  a + bi. The modulus of z is its absolute value. A complex variable may be  graphed as a vector from the origin to the point (a,b) in a rectangular  coordinate system, its modulus corresponding to the vector�s length. Called  an Argand diagram, this representation establishes a connection between  complex analysis and vector analysis. See also Euler's formula.</p><p>composite family Family Compositae, one of the largest plant fami�  lies (also known as Asteraceae, daisy family, and aster family), which con�  tains more than 1,100 genera and almost 20,000 species of herbaceous  plants, shrubs, and trees, found throughout the world. Though diverse in  habit and habitat, composites tend to grow in sunlit places in temperate  and subtropical regions. The family includes many garden ornamentals,  including ageratums, asters, chrysanthemums, cosmos, dahlias, marigolds,  and zinnias. Some genera include weeds such as dandelion, ragweed, and  thistle. Artemisia, artichoke, endive, safflower, salsify, lettuce, and sunflower  are important for the products derived from their flowers, seeds, leaves,  roots, or tubers. Flower heads in this family are composed of many small  flowers (florets) surrounded by bracts. Bell-shaped disk florets form the  centre of each head; strap-shaped ray florets extend out like petals from  the centre and are sometimes reflexed (bent back). Some species have  flowers with only disk or only ray florets.</p><p>composite material Solid material that results when two or more  substances are combined (physically, not chemically) to create a new  material whose properties are superior in a specific application to those  of the original substances. The term specifically refers to a structural  matrix (such as plastic) within which a fibrous material (such as silicon  carbide) is embedded. Fibreglass-reinforced plastic is the best-known  composite. Because of their stiffness, lightness, and heat resistance, com�  posites are the materials of choice in numerous structural, reinforcing, and  high-performance applications.</p><p>compost Mass of rotted organic matter made from decomposed plant  material. It is used in agriculture and gardening generally to improve soil  structure rather than as a fertilizer, because it is low in plant nutrients.  When properly prepared, it is free of obnoxious odours. Composts com�  monly contain about 2% nitrogen, 0.5-1% phosphorus, and about 2%</p><p>potassium. Lime and nitrogen fertilizers and manure may be added to  speed decomposition. The nitrogen of compost becomes available slowly  and in small amounts. Because of their low nutrient content, composts are  applied in large amounts.</p><p>compound Any substance composed of identical molecules consisting  of atoms of two or more elements. Millions are known, each unique, with  unique properties. Most common materials are mixtures of compounds.  Pure compounds can be obtained by physical separation methods, such  as precipitation and distillation. Compounds can be broken down into their  constituents to various degrees or changed into new compounds by chemi�  cal reactions. Atoms always combine into molecules in fixed proportions,  distinguishing compounds from solutions and other mechanical mixtures.  Compounds are often classified as inorganic and organic compounds; coor�  dination complexes, which contain metal atoms (usually transition ele�  ments) bonded to ligands that may be organic, are somewhat in between.  Compounds may also be classified by whether they have ionic or cova�  lent bonds (many include both types).</p><p>comprehension Act of or capacity for grasping with the intellect. The  term is most often used in connection with tests of reading skills and lan�  guage abilities, though other abilities (e.g., mathematical reasoning) may  also be examined. Specialists in administering and interpreting such tests  are known as psychometricians (see psychometrics) or differential psy�  chologists. See also dyslexia; laterality; psychological testing; speech.</p><p>compressed air Air reduced in volume and held under pressure. Force  from compressed air is used to operate numerous tools and instruments,  including rock drills, train brake systems, riveters, forging presses, paint  sprayers, and atomizers. Bellows have been used since the Early Bronze  age to provide air for smelting and forging. The 20th century witnessed  a large increase in the use of compressed-air devices. The introduction of  jet engines for military and passenger aircraft stimulated the use and  improvement of centrifugal and axial-flow compressors. Digital-logic  pneumatic-control components (developed in the 1960s) can be used in  power and control systems (see pneumatic device).</p><p>compression ratio Degree to which the fuel mixture in an internal-  combustion engine is compressed before ignition. It is defined as the vol�  ume of the combustion chamber with the piston farthest out divided by  the volume with the piston in the full-compression position (see piston  and cylinder). A compression ratio of six means that the action of the pis�  ton compresses the mixture to one-sixth its original volume. A high ratio  promotes efficiency but may cause engine knock.</p><p>compressor Machine for increasing the pressure of a gas by mechani�  cally decreasing its volume. Air is the most frequently compressed gas,  but natural gas, oxygen, nitrogen, and other industrially important gases  are also frequently compressed. There are three general types of compres�  sors. Positive-displacement compressors are usually of the reciprocating  piston type (see piston and cylinder), useful for supplying small amounts  of a gas at relatively high pressures. Centrifugal compressors are particu�  larly suited for compressing large volumes of gas to moderate pressures.  Axial compressors are used for jet aircraft engines and gas turbines.</p><p>Compromise of T 850 Series of measures passed by the U.S. Con�  gress to settle slavery issues and avert secession. The crisis arose in late  1849 when the territory of California asked to be admitted to the Union  with a constitution prohibiting slavery. The problem was complicated by  the unresolved question of slavery�s extension into other areas ceded by  Mexico in 1848. In an attempt to satisfy pro- and antislavery forces. Sen.  Henry Clay offered a series of measures that admitted California as a free  state, left the question of slavery in the new territories to be settled by the  local residents, and provided for the enforced return of runaway slaves  and the prohibition of the slave trade in the District of Columbia. Sup�  port from Daniel Webster and Stephen A. Douglas helped ensure passage  of the compromise. Moderates throughout the Union accepted the terms,  which averted secession for another decade but sowed seeds of discord.</p><p>Compromise of 1867 or Ausgleich Vaus-.gllkX Compact that  established the dual monarchy of Austria-Hungary.

The Austrian emperor  Francis Joseph gave Hungary full internal autonomy, together with a  responsible ministry, and in return it agreed that the empire should still  be a single great state for purposes of war and foreign affairs, thus main�  taining its dynastic prestige abroad.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Compton effect &#x25BA; computer graphics I 443</p><p>Compton effect Change in wavelength of X rays and other energetic  forms of electromagnetic radiation when they collide with electrons. It is  a principal way in which radiant energy is absorbed by matter, and is  caused by the transfer of energy from photons to electrons. When pho�  tons collide with electrons that are free or loosely bound in atoms, they  transfer some of their energy and momentum to the electrons, which then  recoil. New photons of less energy and momentum, and hence longer  wavelength, are produced; these scatter at various angles, depending on  the amount of energy lost to the recoiling electrons. The effect demon�  strates the nature of the photon as a true particle with both energy and  momentum. Its discovery in 1922 by Arthur Compton was essential to  establishing the wave-particle duality of electromagnetic radiation.</p><p>Compton, Arthur (Holly) (b.

Cormack (b. 1924), who  shared a 1979 Nobel Prize for their inventions, this major advance in  imaging technology became generally available in the early 1970s. Detec�  tors record the strength of the exiting X-rays; this information is then pro�  cessed by computer to produce a detailed two-dimensional cross-sectional  image of the body. A series of such images in parallel planes or around  an axis can show the location of abnormalities (especially tumours and  other masses) more precisely than can conventional X-ray images.</p><p>computer Programmable machine that can store, retrieve, and process  data. Today�s computers have at least one CPU that performs most cal�  culations and includes a main memory, a control unit, and an arithmetic  logic unit. Increasingly, personal computers contain specialized graphic  processors, with dedicated memory, for handling the computations needed  to display complex graphics, such as for three-dimensional simulations  and games. Auxiliary data storage is usually provided by an internal hard  disk and may be supplemented by other media such as floppy disks or  CD-ROMs. Peripheral equipment includes input devices (e.g., keyboard,  mouse) and output devices (e.g., monitor, printer), as well as the circuitry  and cabling that connect all the components. Generations of computers  are characterized by their technology. First-generation digital computers,  developed mostly in the U.S. after World War II, used vacuum tubes and  were enormous. The second generation, introduced c. 1960, used transis�  tors and were the first successful commercial computers. Third-generation</p><p>computers (late 1960s and 1970s) were characterized by miniaturization  of components and use of integrated circuits. The microprocessor chip,  introduced in 1974, defines fourth-generation computers. See illustration  on following page.</p><p>computer, analog See analog computer  computer, digital See digital computer</p><p>computer-aided software engineering See CASE</p><p>computer animation also known as computer generated  images (CGI) Form of animated graphics that has replaced �stop-  motion� animation of scale-model puppets or drawings. Efforts to lessen  the labour and costs of animation have led to simplification and comput�  erization. Computers can be used in every step of sophisticated  animation�for example, to automate the movement of the rostrum cam�  era or to supply the in-between drawings for full animation. When a  three-dimensional figure is translated into computer terms (digitized), the  computer can generate and display a sequence of images that seem to  move or rotate the object through space. Hence computer animation can  simulate highly complex motion for medical and other scientific research�  ers, as well as for feature films.</p><p>computer architecture Internal structure of a digital computer,  encompassing the design and layout of its instruction set and storage reg�  isters. The architecture of a computer is chosen with regard to the types  of programs that will be run on it (business, scientific, general-purpose,  etc.). Its principal components or subsystems, each of which could be said  to have an architecture of its own, are input/output, storage, communica�  tion, control, and processing.</p><p>computer art Manipulation of computer-generated images (pictures,  designs, scenery, portraits, etc.) as part of a purposeful creative process.  Specialized software is used together with interactive devices such as  digital cameras, optical scanners, styli, and electronic tablets. Because  graphic images require large programs, the computers used in such work  are generally among the fastest and most powerful available. Computer  art has wide applications in advertising, publishing, and film.</p><p>computer-assisted instruction Use of instructional material pre�  sented by a computer. Since the advent of microcomputers in the 1970s,  computer use in schools has become widespread, from primary schools  through the university level and in some preschool programs. Instructional  computers either present information or fill a tutorial role, testing the stu�  dent for comprehension. By providing one-on-one interaction and pro�  ducing immediate responses to input answers, computers allow students  to demonstrate mastery and learn new material at their own pace. A dis�  advantage is that computerized instruction cannot extend the lesson  beyond the limits of the programming.</p><p>computer chip or chip Integrated circuit or small wafer of semicon�  ductor material embedded with integrated circuitry. Chips comprise the  processing and memory units of the modem digital computer (see micro�  processor; RAM). Chip making is extremely precise and is usually done  in a �clean room,� since even microscopic contamination could render  the chip defective. As transistor components have shrunk, the number per  chip has doubled about every 18 months (a phenomenon known as  Moore�s law), from a few thousand in 1971 (Intel Corp.�s first chip) to  millions by 1989. Nanotechnology is expected to make transistors even  smaller and chips correspondingly more powerful in the 21st century.</p><p>computer circuitry Complete path or combination of interconnected  paths for electron flow in a computer. Computer circuits are binary in  concept, having only two possible states. They use on-off switches (tran�  sistors) that are electrically opened and closed in nanoseconds and pico�  seconds (billionths and trillionths of a second). A computer�s speed of  operation depends on the design of its circuitry. Faster rates are achieved  by shortening the time it takes to open and close the switches and by  developing circuit paths that can handle the increased speeds.</p><p>computer graphics Use of computers to produce visual images, or the  images so produced. Creating computer graphics requires a digital computer  to store and manipulate images, a display screen, input/output devices, and  specialized software that enables the computer to draw, colour, and  manipulate images held in memory. Common computer graphic formats  include GIF and JPEG, for single images, and MPEG and Quicktime, for  multiframe images. The field has widespread use in business, scientific  research, and entertainment.

Other peripheral devices may include a printer,  scanner, camera, microphone, or external storage device. Chips and circuit boards ("cards") are plugged into the motherboard. Other components, such as disk drives,  are housed in the computer case and controlled by a card called a controller. The microprocessor directs the computer's activity via the motherboard and processes data  with its millions of transistors. Data and programs in use are stored in the RAM chips. The floppy and hard drives store data not in immediate use on magnetic disks. Opti�  cal disks, such as CD-ROMs and DVDs, may store data as well. Some circuit boards are dedicated to specific functions; the sound card, for example, generates sounds and  music. Additional boards, such as a modem, may be added by inserting them into an expansion slot, a row of electrical connectors into which the board is plugged. The  mouse is an input device used to position a pointer on the computer's screen. On-screen selections are made by "clicking" one of the mouse's buttons, sending a signal to  the computer.</p><p>� ENCYCLOPEDIA BRITANNICA, INC.</p><p>have replaced drafting boards.

The field encompasses theory, mathematical  activities such as design and analysis of algorithms, performance studies  of systems and their components, and estimation of reliability and avail�  ability of systems by probabilistic techniques. Because computer systems  are often too large and complicated for failure or success of a design to  be predicted without testing, experimentation is built into the develop�  ment cycle.</p><p>computer virus Computer program designed to copy itself into other  programs, with the intention of causing mischief or damage. A virus will  usually execute when it is loaded into a computer�s memory. On execu�  tion, it instructs its host program to copy the viral code into any number  of other programs and files stored in the computer. The corrupted pro�  grams may continue to perform their intended functions while also execut�  ing the virus�s instructions, thus further propagating it. The infection may  transfer itself to other computers through storage devices, computer net�  works, and on-line systems. A harmless virus may simply cause a cryptic  message to appear when the computer is turned on; a more damaging virus  can destroy valuable data. Antivirus software may be used to detect and  remove viruses from a computer, but the software must be updated fre�  quently for protection against new viruses.</p><p>computer vision Field of robotics in which programs attempt to iden�  tify objects represented in digitized images provided by video cameras,  thus enabling robots to �see.� Much work has been done on stereo vision  as an aid to object identification and location within a three-dimensional  field of view. Recognition of objects in real time, as would be needed for  active robots in complex environments, usually requires computing power  beyond the capabilities of present-day technology.

U.S. social reformer. He was  an early agitator against abortion and pornography, lobbying successfully  for the enactment (1873) of a severe federal statute outlawing the trans�  portation of obscene matter in the mails (the Comstock Law). In that same  year, he founded the Society for the Suppression of Vice, which he  directed until his death. As a special agent of the U.S. Post Office (1873�  1915), he conducted spectacular raids on publishers and vendors. His  books include Traps for the Young (1883) and Morals Versus Art (1888).</p><p>Comte \'ko n t\, (Isidore-) Auguste (-Marie-Francois-Xavier)</p><p>(b. Jan. 19, 1798, Montpellier,</p><p>France�d.

His ideas influenced  John Stuart Mill (who supported him  financially for many years), Emile  Durkheim, Herbert Spencer, and  Edward Burnett Tylor. His most  important works are Cours de phi-  losophie positive (6 vol., 1830-42)  and Systeme de politique positive (4  vol., 1851-54).</p><p>Conakry Vka-no-.kre, ko-na-'kre\</p><p>Capital (regional pop., 1999 est.: 1,764,000), largest city, and chief Atlan�  tic port of Guinea.

It became the capital successively  of the protectorate of Rivieres du Sud (1891), the colony of French Guinea  (1893), and independent Guinea (1958). Tombo Island, the site of the  original settlement, is linked to the peninsula by a causeway. The city was  industrialized in the 1950s after iron mining and bauxite production had  been developed. It is the seat of the University of Conakry (1962).</p><p>Conall Cernach Vko-n3l-'k y er-n3k\ Legendary warrior of Celtic  mythology who appears in many stories.

July 7, 1930, Crowborough, Sussex, Eng.) Scottish writer. He became a  doctor and practiced until 1891, studying with Dr. Joseph Bell, who was  the model for his fictional detective, Sherlock Holmes. Conan Doyle was  knighted for his medical work in the second South African War and his  public defense of the war. Holmes first appeared in �A Study in Scarlet�  (1887). Collections of Holmes stories began with The Adventures of Sher�  lock Holmes (1892). Tiring of Holmes, Conan Doyle devised his death in  1893, only to be forced by public demand to restore him to life. His other  Holmes novels include The Sign of Four (1890), The Hound of the Basker-  villes (1902), and The Valley of Fear (1915). His historical romances  include The White Company (1890). Late in life, Conan Doyle devoted  himself to spiritualism.</p><p>Conant Vko-n3nt\, James B(ryant) (b. March 26, 1893, Dorchester,  Mass., U.S.�d. Feb. 11, 1978, Hanover, N.H.) U.S. educator and scien�  tist, president of Harvard University (1933-53). Conant received a Ph.D.  (1916) from Harvard and taught chemistry there until he was elected its  president in 1933. He led the university to broaden the social and geo�  graphic makeup of its student body. During World War II he was a cen�  tral figure in organizing American science, including the development of  the atomic bomb. In 1953 he was appointed U.S. high commissioner for  West Germany, and in 1955 he was appointed ambassador. His publica�  tions include chemistry textbooks, works on science for the lay reader,  and books on educational policy.</p><p>concentration camp Internment centre established by a government  to confine political prisoners or members of national or minority groups for  reasons of state security, exploitation, or punishment. The prisoners are  usually selected by executive decree or military order. Camps are usually  built to house many people, typically in highly crowded conditions. Coun�  tries that have used such camps include Britain during the South African  War, the Soviet Union (see Gulag), the U.S. (see Manzanar Relocation  Center), and Japan, which interned Dutch civilians in the Dutch East Indies  during World War II. A variation, called a �reeducation camp,� was widely  used in China during the Cultural Revolution and in Cambodia under the  Khmer Rouge. Most notorious were the death camps of Nazi Germany,  including Auschwitz, Bergen-Belsen, Buchenwald, Dachau, and Treblinka.</p><p>Concepcion \,k6n-sep-'sy6n\ City (pop., 2002 prelim.: 371,000), capi�  tal of Bio-Bio region, south-central Chile. One of Chile�s largest cities, it  was founded in 1550 on the Pacific coast, where it was twice burned by  Araucanian Indians. It has also been struck by numerous earthquakes, two  of which were followed by tsunamis, and in 1754 it was moved inland to  its present site near the mouth of the Bio-Bio River. Despite its severe seis�  mic activity, it has become a major commercial and industrial centre and  a distribution point for southern Chile. Local industries include textiles,  food products, and steel.</p><p>concept formation Process of developing abstract rules or mental  constructs based on sensory experience. Concept formation figures promi�  nently in cognitive development and was a subject of great importance  to Jean Piaget, who argued that learning entails an understanding of a phe�  nomenon�s characteristics and how they are logically linked. Noam Chom�  sky later argued that certain cognitive structures (such as basic  grammatical rules) are innate in human beings. Both scholars held that,  as a concept emerges, it becomes subject to testing: a child�s concept of  �bird,� for example, will be tested against specific instances of birds. The  human capacity for play contributes importantly to this process by allow�  ing for consideration of a wide range of possibilities.</p><p>Conception Bay Inlet of the Atlantic Ocean, southeastern Newfound�  land, Canada.

In the 1960s and �70s it became a  major international movement; its leading exponents were Sol LeWitt (b.  1928) and Joseph Kosuth (b. 1945). Its adherents radically redefined art  objects, materials, and techniques, and began questioning the very exist�  ence and use of art. Its claim is that the �true� work of art is not a physi�  cal object produced by the artist for exhibition or sale, but rather consists  of �concepts� or �ideas.� Typical conceptual works include photographs,  texts, maps, graphs, and image-text combinations that are deliberately  rendered visually uninteresting or trivial in order to divert attention to the  �ideas� they express. Its manifestations have been extremely diverse; a  well-known example is Kosuth�s One and Three Chairs (1965), which  combines a real chair, a photograph of a chair, and a dictionary defini�  tion of �chair.� Conceptual art was fundamental to much of the art pro�  duced in the late 20th century.</p><p>Concert of Europe In the post-Napoleonic era, the consensus among  the European monarchies favoring preservation of the territorial and  political status quo.

The first  concertina was patented by Sir Charles Wheatstone in London in 1829,  and he later produced an instrument with full chromatic capacity. Like the  accordion, its sound is produced by free reeds, but it uses buttons rather  than keys. The very similar Argentinian bandoneon is square rather than  hexagonal.</p><p>concerto \k3n-'cher-to\ Musical composition for solo instrument and  orchestra. The solo concerto grew out of the older concerto grosso.  Giuseppe Torelli�s violin concertos of 1698 are the first known solo con�  certos. Antonio Vivaldi, the first important concerto composer, wrote more  than 350 solo concertos, mostly for violin. Johann Sebastian Bach wrote  the first keyboard concertos. From the Classical period on, most concer�  tos have been written for piano, followed in popularity by the violin and  then the cello. Wofgang Amadeus Mozart wrote 27 piano concertos; other  notable composers of piano concertos include Ludwig van Beethoven, Felix  Mendelssohn, Frederic Chopin, Franz Liszt, and Johannes Brahms. From the  outset the concerto has been almost exclusively a three-movement form,  with fast tempos in the first and third movements and a slow central  movement. It has generally been intended to display the soloist�s virtu�  osity, particularly in the unaccompanied and often improvised cadenzas  near the ends of the first and third movements. Nineteenth-century con�  certos were often conceived as a kind of dramatic struggle between solo�  ist and orchestra; many later composers preferred that the soloist blend  with the orchestra.</p><p>concerto grosso Principal orchestral music of the Baroque era, char�  acterized by contrast between a small group of soloists and a larger orches�  tra. The small group (concertino) usually consisted of two violins and  continuo, the instruments of the older trio sonata, though wind instru�  ments were also used. The larger group (ripieno) generally consisted of  strings with continuo. Alessandro Stradella (1642-82) wrote the first  known concerto grosso c. 1675. Arcangelo Corelli�s set of 12 (c. 1680-  90), Johann Sebastian Bach�s Brandenburg Concertos (c. 1720), and  George Frideric Handel�s Opus 6 concertos (c. 1740) are the most cel�  ebrated examples. From 1750 the concerto grosso was eclipsed by the  solo CONCERTO.</p><p>conch Vkaqk, 'kanch\ Marine snail whose shell has a broadly triangular  outer whorl and a wide lip, often jut�  ting toward the uppermost point.</p><p>True conchs (family Strombidae)  feed on fine plant matter in warm  waters.

In the Ulster cycle he is the ideal Irish king. In The Book of Leinster  (c. 1160), Conor fell in love with the beauty Deirdre. Deirdre, however,  was in love with Nofsi, with whom she eloped and lived in Scotland;  Conor�s slaying of his rival caused a revolt in Ulster, and Deirdre killed  herself.</p><p>Conciliar Movement Vkon-'si-le-orX (1409^19) In Roman Catholi�  cism, an effort to strengthen the authority of church councils over that of  the papacy. Originally aimed at ending the Western Schism, the Conciliar  Movement had its roots in legal and intellectual circles in the 13th cen�  tury but emerged as a force at the Council of Pisa (1409), which elected  a third pope in an unsuccessful attempt to reconcile the parties of the  existing pope and antipope. A second council, the Council of Constance  (1414�18), ended the schism by voiding all papal offices and electing a  new pope. Participants hoped to play an ongoing role in the church, but  the popes continued to seek supremacy, and the Council of Basel (1431�  49) ended fruitlessly.</p><p>conclave In the Roman Catholic church, the assembly of cardinals gath�  ered to elect a new pope and the system of strict seclusion to which they  submit. From 1059 the election became the responsibility of the cardi�  nals. When, after the death of Clement IV (1268), the cardinals dithered  for more than two years, the local magistrate locked them in the episco�  pal palace and fed them only bread and water until they elected Gregory  X. The system of meeting in closed conclave was codified in 1904 by Pius  X. Voting is by secret ballot; one ballot is held on the first afternoon of  the conclave and four on each subsequent day, two in the morning and  two in the afternoon, until a new pope is chosen. In 1996 John Paul II  declared that, after 30 ballots, the traditional requirement of a two-thirds  majority plus one for the election of a pope could be superseded, at the  discretion of the cardinals, by election by a simple majority. Ballots are  burned in a stove after each vote, and the smoke produced by their burn�  ing, which issues from a special pipe through a window, indicates to the  crowd assembled in St. Peter�s Square whether a new pope has been  elected: if there is a new pope, the smoke will be white; if no majority  has yet been reached, the smoke will be black. In addition, bells will be  rung to confirm the signal. Additives are mixed with the ballots to ensure  the proper colour of the smoke.</p><p>Concord Vkan-kord, 'kan-,k6rd\ City (pop., 2000: 121,780), western  California, U.S. Located near San Francisco, it was laid out in 1868 as  Todos Santos and renamed in 1869 for Concord, Mass.

Renamed Concord in 1765, it was made the  capital in 1808. Printing, carriage making, and granite quarrying were  important in its early development; Concord granite is still quarried.</p><p>Concord, Battles of Lexington and See Battles of Lexington and  Concord</p><p>Concordat of 1801 Agreement between Napoleon and Pope Pius VII  that defined the status of the Roman Catholic Church in France and ended  the breach caused by the church reforms of the French Revolution (see  Civil Constitution of the Clergy). The Roman Catholic faith was acknowl�  edged as the religion of the majority of the French people but was not  proclaimed as the established religion of the state. Napoleon gained the  right to nominate bishops, but their offices were conferred by the pope.  The government agreed to pay the clergy, but confiscated church prop�  erty was not restored.

He distinguished himself in battles  with Spain in the Thirty Years� War, and in 1649 he helped suppress the  Fronde uprising. After being arrested by Mazarin in 1650, he rebelled and  led the second Fronde, fighting from Spain until he was defeated at the  Battle of the Dunes in 1658. Pardoned the next year, he again became one  of Louis XIV�s greatest generals, winning numerous battles in Spain,  Germany, and Flanders. He was a man of great courage, unconventional  habits, and sound independence of mind; broadly cultivated, he counted  Mouere and Jean Racine among his friends. See also Conde family.</p><p>Conde \k6n-'da\ family Important French branch of the house of Bour�  bon, whose members played a significant role in French dynastic politics.  The line began with Louis I de Bourbon (1530-69), 1st prince de Conde,  a military leader of the Huguenots in France�s Wars of Religion. The fami�  ly�s most prominent member was the 4th prince de Cond�, one of Louis  XIV� s greatest generals. The princely line died out when Louis-Antoine-  Henri de Bourbon-Conde (1772-1804), duke d�Enghien and sole heir of  the last prince de Conde, was falsely arrested and, on Napoleon�s orders,  shot for treason.</p><p>condensation Formation of a liquid or solid from its vapour. Conden�  sation usually occurs on a surface that is cooler than the adjacent gas. A  substance condenses when the pressure exerted by its vapour exceeds the  vapour pressure of its liquid or solid phase at the temperature of the sur�  face where the condensation is to occur. The process causes the release  of thermal energy. Condensation occurs on a glass of cold water on a warm,  humid day when water vapour in the air condenses to form liquid water  on the glass�s colder surface. Condensation also accounts for the forma�  tion of dew, fog, rain, snow, and clouds.</p><p>condenser Device for reducing a gas or vapour to a liquid. Condens�  ers are used in power plants to condense exhaust steam from turbines and  in refrigeration plants to condense refrigerant vapours, such as ammonia  and Freons. The petroleum and chemical industries use condensers for  hydrocarbons and other chemical vapours. In distillation, a condenser  transforms vapour to liquid. All condensers work by removing heat from</p><p>the gas or vapour. In some, the gas passes through a long tube of heat-  conductive metal, such as copper (usually arranged in a coil or other  compact shape), and heat escapes into the surrounding air. Large indus�  trial condensers use water or some other liquid to remove the heat. The  term condenser also refers to a device attached to carding machines in  textile factories to collect fibres into roving for spinning machines.</p><p>Condillac \ko n -de-'yak\, Etienne Bonnot de (b. Sept. 30, 1715,  Grenoble, France�d. Aug. 2/3, 1780, Flux) French philosopher, psy�  chologist, and economist. He was ordained a priest in 1740. In his Essay  on the Origin of Human Knowledge (1746), he systematically discussed  the empiricism of John Locke. In Treatise on Sensations (1754), he ques�  tioned Locke�s doctrine that intuitive knowledge is available directly  through the senses. In his works Logic (1780) and The Language of Cal�  culation (1798), he emphasized the importance of language in logical rea�  soning and stressed the need for a scientifically designed language. His  economic views, presented in Commerce and Government (1776), were  based on the notion that value depends on utility rather than labour. The  need for something useful, he argued, gives rise to value, while prices  result from the exchange of valued items.</p><p>conditioning Process in which the frequency or predictability of a  behavioral response is increased through reinforcement (i.e., a stimulus  or a reward for the desired response). Classical, or respondent, condition�  ing, which involves stimulus substitution, is based on the work of Ivan  Pavlov, who conditioned dogs by ringing a bell each time the aroma of  food was presented. Eventually the dogs salivated when the bell rang,  even if no food odour was present; salivation was thus the conditioned  response. In instrumental, or operant, conditioning, a spontaneous (oper�  ant) behaviour is either rewarded (reinforced) or punished. When  rewarded, a behaviour increases in frequency; when punished, it  decreases. Operant conditioning was studied in detail by B.F. Skinner.</p><p>condominium In modern property law, individual ownership of one  dwelling unit within a multidwelling building. Unit owners have undi�  vided ownership interest in the land and those portions of the building  shared in common. This type of ownership has been present in Europe  since the end of the Middle Ages; in the U.S. it dates to the latter half of  the 19th century and has been popular in crowded urban areas. An alter�  native to the condominium is the cooperative, in which residents own a  share of a corporation, with each share entitling the owner to reside in a  particular unit in the building.</p><p>condor Either of two species of large New World vultures. Two of the  largest flying birds, each is about 4 ft (1.2 m) long. Both feed on dead  animals. The Andean condor ( Vultur gryphus ), which ranges from the  Pacific coast of South America to the high Andes Mountains, has slightly  longer wings (10 ft [3 m]) and is black with a white ruff and bare pinkish  head and neck. The California condor ( Gymnogyps californianus) is  nearly black, with white wing linings, a bare yellow head, and a red neck.  It hovered on the brink of extinction in the 1980s, and every California  condor was captured. Careful nurturing has since led to the release of more  than 200 condors into the wild.</p><p>Condorcet \k6 n -d6r-'se\, Marie-Jean-Antoine-Nicolas de Car-  itat, marquis de (b. Sept. 17, 1743, Ribemont, France�found dead  March 29, 1794, Bourg-la-Reine) French mathematician, statesman, and  revolutionary. He showed early promise as a mathematician and was a  protege of Jean Le Rond d'Alembert. In 1777 he became secretary of the  Academy of Sciences. In sympathy with the French Revolution, he was  elected to represent Paris in the Legislative Assembly (1791-92), where  he called for a republic. His opposition to the arrest of the moderate  Girondins led to his being outlawed (1792). While in hiding he wrote his  famous Sketch for a Historical Picture of the Progress of the Human Mind,  in which he advanced the idea of the continuous progress of the human  race to an ultimate perfection. He was captured and subsequently found  dead in prison.</p><p>conducting Art of leading a group of musical performers. Simple coor�  dination of a group does not always require a conductor (members of a  Renaissance choir kept together by one tapping another on the shoulder,  for example, and musicians in a recording studio listen to a �click track�  on headphones). Before c. 1800, the first violinist usually gave the few  necessary signals with his bow; the keyboard player might also lead the  orchestra, using his hands and head. In the 19th century the larger size of  ensembles and growing complexity of music, including its varying tem�  pos and heightened expressiveness, made it necessary for a person to</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>448 I conduction &#x25BA; Confucianism</p><p>coordinate and interpret the music for the group. The first conductors,  including Felix Mendelssohn, Hector Berlioz, and Richard Wagner, were  composers themselves. By the end of the 19th century, conducting had  become a specialty and the great conductors had become celebrities in  their own right.</p><p>conduction See thermal conduction</p><p>conductor Any of various substances that allow the flow of electric cur�  rent or thermal energy. A conductor is a poor insulator because it has a low  resistance to such flow. Electrical conductors are used to conduct electric  current, as in the metal wires of an electric circuit. Electrical conductors  are usually metallic. Thermal conductors allow thermal energy to flow  because they do not absorb radiant heat; they include materials such as  metal and glass.</p><p>cone or strobilus \stro-'bI-l9s, 'stro-b9-bs\ In botany, a mass of scales  or bracts, usually ovate, containing the reproductive organs of certain  non-flowering plants. A distinguishing feature of pines and other conifers,  the cone is roughly analogous to the flower of other plants. Cones (stro-  bili) are also found on club mosses and horsetails.</p><p>conef lower Any of three genera ( Echinacea , Ratibida, and Rudbeckia).  They are weedy plants in the composite family, native to North America.  Some species in each genus have reflexed ray flowers. The purple-  flowered perennials E. angustifolia and E. purpurea are often cultivated  as border plants; they have strong-smelling black roots and hairy stems.  These two species, along with E. pallida, are used to prepare an herbal  cold and flu remedy called echinacea. Ratibida species have yellow ray  flowers and brownish disk flowers. Prairie coneflowers {Ratibida colum-  naris and R. pinnata ) are grown in wildflower gardens. Rudbeckia spe�  cies have yellow ray flowers and brown or black disk flowers. Black-eyed  Susan {Rudbeckia hirta ), thimble-flower {R. bicolor ), and cutleaf cone-  flower {R. laciniata) are grown as border plants.</p><p>Conestoga wagon Horse-drawn covered freight wagon. It originated  in the 18th century in the Conestoga Creek region of Pennsylvania. It had  a flat body and low sides; with its floor curved up at each end to prevent  freight from shifting, it was well suited for travel over early American  roads. It became famous as later adapted by westward-traveling pioneers  for hauling their possessions; with its tall white canvas top, it resembled a  sailing ship from a distance, which earned it the name �prairie schooner.�</p><p>coney See cony</p><p>Coney Island Amusement area, southern Brooklyn, N.Y., U.S. It was  an island in the Atlantic Ocean until its creek silted up and it became part  of Long Island. The first pavilion and bathhouse were erected in 1844, and  it gained popularity with the coming of the subway in 1920. It has a 3.5-mi  (5.6-km) boardwalk and an amusement park known for its roller coaster  (the Cyclone). It is also the site of the New York Aquarium.</p><p>Confederate States of America or Confederacy Government  of the 11 Southern states that seceded from the Union in 1860-61 until  its defeat in the American Civil War in 1865. In the months following  Abraham Lincoln�s election as president in 1860, seven states of the Deep  South (Alabama, Florida, Georgia, Louisiana, Mississippi, South Caro�  lina, and Texas) seceded. After the attack on Fort Sumter in April 1861,  Arkansas, North Carolina, Tennessee, and Virginia joined them. The gov�  ernment was directed by Jefferson Davis as president, with Alexander H.  Stephens as vice president. Its principal goals were the preservation of  states' rights and the institution of slavery. The government�s main con�  cern was raising and maintaining an army. It counted on the influence of  King Cotton to exert financial and diplomatic pressure on the Union from  sympathetic European governments. Battlefield victories for the South in  1861-62 gave the Confederacy the moral strength to continue fighting,  but from 1863 dwindling finances and battlefield reverses increasingly led  to demoralization. The surrender at Appomattox Court House by Gen. Rob�  ert E. Lee precipitated its dissolution.</p><p>Confederation, Articles of See Articles of Confederation</p><p>Confederation of the Rhine (1806-13) Union of all the states of  Germany, except Austria and Prussia, under the aegis of Napoleon. Napo�  leon�s primary interest in the confederation, which enabled the French to  unify and dominate the country, was as a counterweight to Austria and  Prussia. The confederation was abolished after Napoleon�s fall from  power, but the consolidation it entailed contributed to the movement for  German unification.</p><p>Confessing Church German Bekennende Kirche Movement for  revival within the German Protestant churches that developed in the 1930s  in resistance to Adolf Hitler�s attempt to make the churches an instrument  of Nazi propaganda and politics. The Confessing Church, whose leaders  included Martin Niemoller and Dietrich Bonhoeffer, opposed Hitler�s �Ger�  man Christians� and was forced underground as Nazi pressure intensi�  fied. The movement continued in World War II, though it was hampered  by the conscription of clergy and laity. In 1948 the church ceased to exist  when the reorganized Evangelical Church was formed.</p><p>confession In the Judeo-Christian tradition, acknowledgment of sin�  fulness, in public or private, regarded as necessary for divine forgiveness.  In the Temple period, Yom Kippur included a collective expression of sin�  fulness, and the day continues in Judaism as one of prayer, fasting, and  confession. The early Christian Church followed John the Baptist�s prac�  tice of confession before baptism, but soon instituted confession and pen�  ance for the forgiveness of sins committed after baptism. The fourth  Lateran Council (1215) required annual confession. The Roman Catholic  and Eastern Orthodox churches consider penance a sacrament, but most  Protestant churches do not.</p><p>confidential communication See privileged communication</p><p>configuration In chemistry, the arrangement in space of the atoms in  a molecule. It is especially important in organic chemistry (see organic  compound), in which each carbon atom in a molecule can form from two  to four covalent bonds (see bonding) with as many as four other atoms.  A carbon atom with four single bonds, for example, lies at the centre of  a tetrahedron, with one bond extending to each comer; if three or all four  atoms bonded to the carbon are different, the structure that results has two  different mirror-image (see optical activity; isomer) forms, similar to left-  and right-handed gloves. Configuration issues also apply to some inor�  ganic compounds. Until late in the 20th century, chemists struggled to  determine the true three-dimensional form (absolute configuration) of a  molecule experimentally, but modem optical and chemical methods have  greatly simplified the task. The term electronic configuration refers to the  number of electrons in the various shells of an atom, which defines its  chemical reactivity and the type of bonding in which it participates.</p><p>confirmation Christian rite in which believers reaffirm the faith into  which they were baptized as infants or young children. The rite admitting  adults to full membership in the community of the faithful did not exist  as a distinct ceremony in the early church but probably coincided with  baptism, since those who joined did so as adults and were baptized after  instruction. As baptism of infants became common, some means of ascer�  taining their knowledge and commitment as young adults became neces�  sary. A period of instruction was introduced, after which the candidates  were examined and confirmed. In Roman Catholicism confirmation  became a sacrament, usually performed by a bishop. The rite is also used  in the Anglican and Lutheran churches.</p><p>confiscation In law, the act of seizing property without compensation  and submitting it to the public treasury. Illegal items such as narcotics or  firearms, or profits from the sale of illegal items, may be confiscated by  the police. Additionally, government action (e.g., zoning or rate setting)  that reduces the value of property to an owner so as to make it nearly  worthless has been held to constitute confiscation. See also eminent domain,  SEARCH AND SEIZURE.</p><p>conflict In psychology, a struggle resulting from incompatible or oppos�  ing needs, drives, wishes, or demands. Interpersonal conflict represents  such a struggle between two or more people, while internal conflict is a  mental struggle. A child experiencing internal conflict, for example, may  be dependent on his mother but fear her because she is rejecting and puni�  tive. Conflicts that are not readily resolved may cause the person to suf�  fer helplessness and anxiety. See also learned helplessness.</p><p>conformal map In mathematics, a transformation of one graph into  another in such a way that the angle of intersection of any two lines or  curves remains unchanged. The most common example is the Mercator  map, a two-dimensional representation of the surface of the earth that pre�  serves compass directions. Other conformal maps, sometimes called orth-  omorphic projections, preserve angles but not shapes.</p><p>Confucianism Scholarly tradition and way of life propagated by Con�  fucius in the 6th-5th century bc and followed by the Chinese for more  than two millennia. Though not organized as a religion, it has deeply  influenced East Asian spiritual and political life in a comparable manner.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Confucius &#x25BA; Congo I 449</p><p>The core idea is ren (�humaneness,� �benevolence�), signifying excellent  character in accord with li (ritual norms), zhong (loyalty to one�s true  nature), shu (reciprocity), and xiao (filial piety). Together these constitute  de (virtue). Mencius, Xunzi, and others sustained Confucianism, but it was  not influential until Dong Zhongshu emerged in the 2nd century bc. Con�  fucianism was then recognized as the Han state cult, and the Five Classics  became the core of education. In spite of the influence of Daoism and Bud�  dhism, Confucian ethics have had the strongest influence on the moral fab�  ric of Chinese society. A revival of Confucian thought in the 11th century  produced Neo-Confucianism, a major influence in Korea during the  Choson dynasty and in Japan during the Tokugawa period.</p><p>Confucius Chinese Kongfuzi or K'ung-fu-tzu Vkuq-'fu-'dzoV (b.  551 bc, Ch�ii-fu, state of Lu�d. 479, Lu) Ancient Chinese teacher, phi�  losopher, and political theorist. Born into a poor family, he managed  stables and worked as a bookkeeper while educating himself. Mastery of  the six arts�ritual, music, archery, charioteering, calligraphy, and  arithmetic�and familiarity with history and poetry enabled him to begin  a brilliant teaching career in his thirties. Confucius saw education as a  process of constant self-improvement and held that its primary function  was the training of noblemen (junzi ). He saw public service as the natu�  ral consequence of education and sought to revitalize Chinese social insti�  tutions, including the family, school, community, state, and kingdom. He  served in government posts, eventually becoming minister of justice in  Lu, but his policies attracted little interest. After a 12-year self-imposed  exile during which his circle of students expanded, he returned to Lu at  age 67 to teach and write. His life and thoughts are recorded in the Lunyu  C Analects ).

It contains the last significant tract of virgin South�  ern bottomland hardwoods in the southeastern U.S., including loblolly  pine, water tupelo, hickory, and oak, some of record size.</p><p>congenital disorder Structural abnormality (e.g., atresia, agenesis),  functional problem (e.g., cystic fibrosis, phenylketonuria), or disease present  at birth. Almost all are due to genetic factors (inherited or spontaneous  mutations, chromosomal disorders), environmental influences during preg�  nancy (rubella or other maternal factors, exposure to toxins or radiation),  or both. The most sensitive period is the first eight weeks after concep�  tion, during which time the human embryo is essentially formed. Major  congenital malformations form during this period. Some inherited disor�  ders result from simple Mendelian dominance or recessiveness. Others may  involve multiple genes. Chromosomal disorders are rare, because few  affected fetuses survive to be bom. Environmental influences may affect  only one of a pair of identical twins. At least 30 significant defects prob�  ably occur per 1000 births. See also birth defect; Down syndrome.</p><p>congenital heart disease Deformity of the heart. Examples include  septal defect (opening in the septum between the sides of the heart), atre�  sia (absence) or stenosis (narrowing) of one or more valves, tetralogy of  Fallot (with four components: ventricular septal defect, pulmonary valve  stenosis, right ventricular enlargement, and positioning of the aorta so  that it receives blood from both ventricles), and transposition of the great  vessels (so the pulmonary and systemic circulations each receive blood  from the wrong side of the heart). Such defects can prevent enough oxy�  gen from reaching the tissues, so the skin has a bluish cast. Many are fatal  if not corrected surgically soon after birth�or, rarely, before birth, if  detected prenatally. Abnormalities of the large vessels are usually less  serious (see aorta, coarctation of; ductus arteriosus).</p><p>conger eel Any of about 100 species of marine eels (family Congridae)  with no scales, a large head, large gill slits, a wide mouth, and strong  teeth. Conger eels are usually grayish to blackish, with a paler belly and  black-edged fins. Found in all oceans, sometimes in deep water, they may  grow about 6 ft (1.8 m) long. Conger eels are carnivores. Many species,  such as the European conger (Conger conger ), are valued as food. The  American conger, or sea eel (C. oceanicus), is a fierce game fish.</p><p>congestive heart failure Heart failure resulting in the accumulation  of fluid in the lungs and other body tissues. It is related mainly to salt and  water retention in the tissues rather than directly to reduced blood flow.  Blood pools in the veins (vascular congestion) because the heart does not  pump efficiently enough to allow it to return. It may vary from the most  minimal symptoms to sudden pulmonary edema or a rapidly lethal shock�</p><p>like state (see shock). Chronic states of varying severity may last years.  Symptoms tend to worsen as the body�s attempts to compensate for the  condition create a vicious circle. The patient has trouble breathing, at first  during exertion and later even at rest. Treatment is directed toward  increasing the strength of the heart�s muscle contraction, reduction of fluid  accumulation, and elimination of the underlying cause of the failure.</p><p>conglomerate Vkon-'gla-mo-rsA In petrology, lithified sedimentary  rock consisting of rounded fragments larger than 0.08 in.

Conglomerate mergers are undertaken for many reasons,  including the prospect of making additional use of existing facilities,  improving the corporation�s overall marketing position, decreasing the  risk of relying on a single type of product, and effecting corporate reor�  ganization. The practice was widespread in the 1960s and 1980s, but in  the 1990s many conglomerates began to sell off unwanted subsidiaries.</p><p>Congo, Democratic Republic of the known as Congo (Kin�  shasa) formerly (1971-97) Republic of Zaire Country, central  Africa.

Its economy is based on mining and agri�  culture. Exports include diamonds, petroleum, and coffee; mining pro�  duces copper, cobalt, and industrial diamonds. The country has a  transitional government; the head of state and government is the presi�  dent, assisted by four vice presidents. Prior to European colonization,  several kingdoms had emerged in the region, including the 16th-century  Luba kingdom and the Kuba federation, which reached its peak in the  18th century. European development began late in the 19th century when  King Leopold II of Belgium financed Henry Morton Stanley�s exploration</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>450 I Congo &#x25BA; Congreve</p><p>of the Congo River. The 1884-85 Berlin West Africa Conference recog�  nized the Congo Free State with Leopold as its sovereign. The growing  demand for rubber helped finance the exploitation of the Congo, but  abuses against local peoples outraged Western nations and forced Leopold  to grant the Free State a colonial charter as the Belgian Congo (1908).  Independence was granted in 1960. The postindependence period was  marked by unrest, culminating in a military coup that brought Gen.  Mobutu Sese Seko to power in 1965. He changed the country�s name to  Zaire in 1971. Mismanagement, corruption, and increasing violence dev�  astated the infrastructure and economy. Mobutu was deposed in 1997 by  Laurent Kabila, who restored the country�s name to Congo. Instability in  neighbouring countries, an influx of refugees from Rwanda, and a desire  for Congo�s mineral wealth led to military involvement by various Afri�  can countries.

A narrow coastal plain edges  Congo�s 100-mi (160-km) stretch of Atlantic coastline, rising into low  mountains and plateaus that slope eastward in a vast plain to the Congo  River. The country straddles the Equator; rainforests cover nearly two-  thirds of the land, and wildlife is abundant. Congo has a mixed, devel�  oping economy. Mining products, crude petroleum, and natural gas  account for more than 90% of the country�s exports. A 1997 transitional  constitution vested executive power in the president and legislative power  in a national transitional council. In precolonial days the area was home  to several thriving kingdoms, including the Kongo, which had its begin�  nings in the 1st millennium ad. The save trade began in the 15th century  with the arrival of the Portuguese; it supported the local kingdoms and  dominated the area until its suppression in the 19th century. The French  arrived in the mid-19th century and established treaties with two of the  kingdoms, placing them under French protection prior to their becoming  part of the colony of French Congo. In 1910 it was renamed French Equa�  torial Africa, and the area of the Congo became known as Middle (Moyen)  Congo. In 1946 Middle Congo became a French overseas territory, and  in 1958 it voted to become an autonomous republic within the French  Community. Full independence came two years later. The area has suffered  from political instability since independence. Congo�s first president was</p><p>ousted in 1963. A Marxist party, the Congolese Labor Party, gained  strength, and in 1968 another coup, led by Major Marien Ngouabi, cre�  ated the People�s Republic of the Congo. Ngouabi was assassinated in  1977. A series of military rulers followed, at first militantly socialist but  later oriented toward social democracy. Fighting between local militias in  1997 badly disrupted the economy; a peace process was under way at the  beginning of the 21st century.</p><p>Congo Free State See Democratic Republic of the Congo</p><p>Congo River or Zaire \za-'ir\ River River, west-central Africa.

It developed  as one branch of Puritanism and emphasized the right and duty of each  congregation to govern itself independent of higher human authority. Its  greatest influence and numbers were in the U.S., where Puritans first  established it at Plymouth Colony. The HalfWay Covenant (1662) loos�  ened requirements for church membership, and the Great Awakening led  U.S. Congregationalism away from its Calvinist roots. Many churches  defected to Unitarianism. In general, Congregationalists eschew creeds and  emphasize preaching over sacraments, accepting only baptism and the  Eucharist. English Congregationalists are now part of the United Reform  Church. Most American Congregationalists are now part of the United  Church of Christ. Baptist, Disciples of Christ, and Unitarian Universalist  churches also practice congregational polity.</p><p>Congress of the United States Legislature of the U.S., separated  structurally from the executive and judicial (see judiciary) branches of gov�  ernment. Established by the Constitution of the United States, it succeeded  the unicameral congress created by the Articles of Confederation (1781).  It consists of the Senate and the House of Representatives. Representa�  tion in the Senate is fixed at two senators per state. Until passage of the  17th Amendment (1913), senators were appointed by the state legisla�  tures; since then they have been elected directly. In the House, represen�  tation is proportional to each state�s population; total membership is  restricted (since 1912) to 435 members (the total rose temporarily to 437  following the admission of Hawaii and Alaska as states in 1959). Con�  gressional business is processed by committees: bills are debated in com�  mittees in both houses, and reconciliation of the two resulting versions  takes place in a conference committee. A presidential veto can be over�  ridden by a two-thirds majority in each house. Congress�s constitutional  powers include the setting and collecting of taxes, borrowing money on  credit, regulating commerce, coining money, declaring war, raising and  supporting armies, and making all laws necessary for the execution of its  powers. All finance-related legislation must originate in the House; pow�  ers exclusive to the Senate include  approval of presidential nomina�  tions, ratification of treaties, and  adjudication of impeachments.

If the plane is perpendicular to the cone�s  axis, the resulting curve is a circle. Intersections at other angles result in  ellipses, parabolas, and hyperbolas. The conic sections are studied in Euclidean  geometry to analyze their physical properties and in analytic geometry to  derive their equations. In either context, they have useful applications to  optics, antenna design, structural engineering, and architecture.</p><p>conifer Any member of the order Coniferales, woody plants that bear  their seeds and pollen on separate, coNE-shaped structures. They constitute  the largest division of gymnosperms, with more than 550 species. Most are  evergreen, upright trees and shrubs. They grow throughout the world  (except in Antarctica) and prefer temperate climate zones. Conifers  include the pines ( Pinus ), junipers ( Juniperus ), spruces ( Picea ), hemlocks  ( Tsuga ), firs (Abies), larches (Larix), YEWS ( Taxus ), cypresses ( Cupressus ),  bald cypress cypresses ( Taxodium ), Douglas firs (Pseudotsuga), arborvitaes  (Thuja), and related groups. They include the world�s smallest and tallest  trees. Conifers supply softwood timber used for general construction,  mine timbers, fence posts, poles, boxes and crates, and other articles, as  well as pulpwood for paper. The wood is also used as fuel and in the  manufacture of cellulose products, plywood, and veneers. The trees are  the source of resins, volatile oils, turpentine, tars, and pharmaceuticals.  Conifer leaves vary in shape but generally have a reduced surface area to  minimize water loss. Especially in the pines, firs, and spruces, the leaves  are long and stiff and are commonly referred to as needles. Cypresses,  cedars, and others have smaller, scalelike leaves. Conifers were the domi�  nant type of vegetation just before the advent of angiosperms (see flow�  ering PLANT).</p><p>conjoined twins or Siamese twins Identical twins (see multiple  birth) whose embryos did not separate completely. Conjoined twins are  physically joined (typically along the trunk or at the front, side, or back  of the head) and often share some organs. Symmetrical conjoined twins  usually have no birth anomalies except at the areas of fusion and can  sometimes be separated by surgery. In asymmetrical conjoined twins, one  is fairly well developed, but the other is severely underdeveloped and  dependent on the larger twin for nutrition. The underdeveloped twin may  have to be surgically separated to save the larger twin. The term origi�  nally referred to Chang and Eng, bom in 1811 in Siam, who were joined  by a ligament from breastbone to navel. Widely exhibited, they married  two sisters and fathered several children.</p><p>conjugation Interaction of adjacent bonds in a chemical compound  having alternating single and double covalent bonds. The conjugated  bonds show modified characteristics because of increased electron delo�  calization and sharing. Conjugation occurs, for example, within a mol�  ecule containing a chain of carbon atoms linked by alternating single and  double bonds. Such a conjugated system often gives rise to substances  with intense colours�e.g., the biological pigments called carotenes.  Another example is the carboxyl group (see carboxylic acid; functional  group), in which the double bond of the carbonyl group (�C=0) is  adjacent to the single bond attaching the hydroxyl group (�OH) to the  carbon atom.</p><p>conjunctivitis Inflammation of the conjunctiva, the delicate lining of  the eyelids and the front of the white of the eye. It may be caused by infec�  tion (when it is commonly called �pink eye�), chemical burn, physical  injury, or allergy. Often the cornea is also inflamed (keratoconjunctivitis).  Infectious causes include several viruses and bacteria, including those that  cause trachoma and gonorrhea, both of which can lead to blindness. Con�  junctivitis from erythema multiforme, a skin eruption, can also cause  blindness.</p><p>conjuring Art of entertaining by giving the illusion of performing  impossible feats. The conjurer is an actor who combines psychology,  manual dexterity, and mechanical aids to effect the desired illusion. The  form was established by the medieval era, when traveling conjurers per�  formed at fairs and in the homes of the nobility. In the 19th-20th centuries,  conjuring was performed on stage by magicians such as Jean-Eugene  Robert-Houdin, Harry Houdini, and Harry Blackstone. In the late 20th cen�  tury magicians such as Doug Henning and David Copperfield performed  colourful spectacles on television, while the postmodern team Penn and  Teller offered a quieter brand of magic that emphasized irony and illusion.</p><p>Conkling, Roscoe (b. Oct. 30, 1829, Albany, N.Y., U.S.�d. April 18,  1888, New York, N.Y.) U.S. politician. He was a lawyer, orator, and leader  of the Whig Party. He served in the U.S. House of Representatives (1859�  65) and Senate (1867-81). As a leader of the Radical Republicans, he sup�  ported severe Reconstruction measures. Resisting efforts by Pres.  Rutherford B. Hayes to achieve civil service reform, he retained control of  New York state�s patronage system. At the 1880 Republican convention,  he led the Stalwart faction in supporting former Pres. Ulysses S. Grant.  In 1881 he resigned from the Senate in a patronage dispute with Pres.  James Garfield.</p><p>Connacht or Connaught Vka-,n6t\ Province (pop., 2002 prelim.:  464,050), northwestern Ireland. It is composed of the counties of Galway,  Leitrim, Mayo, Roscommon, and Sligo and has an area of 6,611 sq mi  (17,122 sq km). An ancient kingdom, Connacht was Christianized by St.  Patrick in the 5 th century. Dominated from the 11th century by the  O�Connors of Roscommon, it endured an Anglo-Norman invasion in the  12th century.</p><p>Connecticut State (pop., 2000: 3,405,565), northeastern U.S. The south�  ernmost of the New England states, it lies on Long Island Sound and is bor�  dered by Massachusetts, Rhode Island, and New York. It covers 5,006 sq  mi (12,966 sq km); its capital is Hartford. The original inhabitants were  Algonquian- speaking Indians. The area was colonized by English Puritans  from the Massachusetts Bay Colony during the 1630s. One of the original  states of the Union, it was the fifth to ratify the U.S. Constitution. It was an  agricultural region until the early 19th century, when textile factories were  established, and by 1850 employment in manufacturing exceeded agricul�  ture; the state remains a manufacturing centre. New Haven, home of Yale  University, is one of New England�s largest ports, while Stamford is the  headquarters for some of the U.S.�s largest corporations. New London is  home to the U.S. Coast Guard Academy. Highways and railways traverse  Connecticut and serve the densely settled coastal and Connecticut River val�  ley regions. The state abounds with historical sites and memorials, and  there are numerous state forests and state parks.</p><p>Connecticut River River, New England, northeastern U.S. Rising in  the Connecticut Lakes in northern New Hampshire, it flows south for a  course of 407 mi (655 km) to empty into Long Island Sound. It forms the  entire boundary between Vermont and New Hampshire. The lower 60 mi  (97 km) of the river are tidal. The longest river in New England, it is  extensively developed for hydroelectric power.</p><p>connectionism In cognitive science, an approach that proposes to model  human information processing in terms of a network of interconnected  units operating in parallel. The units are typically classified as input units,  hidden units, or output units. Each unit has a default activation level that  can vary as a function of the strength of (1) the inputs it receives from  other units, (2) the different weights associated with its connections to the  other units, and (3) its own bias. Connectionism, unlike traditional com�  putational models in cognitive science, holds that information is distrib�  uted throughout entire networks instead of being localized in functionally  discrete, semantically interpretable states.</p><p>connective tissue Tissue in the body that maintains the form of the  body and its organs and provides cohesion and internal support, includ�  ing BONE, LIGAMENTS, TENDONS, CARTILAGE, ADIPOSE TISSUE, and aponeuroses. Its  major components are different kinds of cells and extracellular fibres and  ground substance, which varies in consistency from thin gel to rigid struc�  ture. Various combinations of these elements make up the different kinds  of connective tissue. Connective tissue diseases are either genetic disor�  ders, attacking one of its elements (e.g., Marfan syndrome), or acquired  inflammatory or immune-system diseases (e.g., rheumatoid arthritis,  OSTEOARTHRITIS, systemic LUPUS ERYTHEMATOSUS, and RHEUMATIC FEVER).</p><p>Connelly, Marc(us Cook) (b. Dec. 13, 1890, McKeesport, Pa.,  U.S.�d. Dec. 21, 1980, New York, N.Y.) U.S. playwright, screenwriter,  and director. He covered theatrical news as a journalist in Pittsburgh and  New York City. He collaborated with George S. Kaufman on the play  Dulcy (1921), which they followed with the comedies To the Ladies  (1922) and Beggar on Horseback (1924) and the librettos for the musi�  cals Helen of Troy, New York (1923) and Be Yourself ( 1924). Connelly  went on to write Green Pastures (1930, Pulitzer Prize; film, 1936), his  best-known work, and The Farmer Takes a Wife (1934; film, 1935).</p><p>Connery, Sir Sean orig. Thomas Connery (b.

In 1953 she  became the first woman to win the grand-slam (the Wimbledon, U.S.,  Australian, and French singles competitions). Her career was ended in  1954 by a horseback-riding accident.</p><p>Connor, Ralph orig. Charles William Gordon (b. Sept. 13,1860,  Indian Lands, Glengarry county, Ont., Can.�d. Oct. 31, 1937, Winnipeg,  Man.) Canadian novelist. Ordained a Presbyterian minister in 1890, Con�  nor became a missionary to mining and lumber camps in the Canadian  Rocky Mountains; this experience and memories of his childhood in Glen�  garry, Ont., provided material for his novels, including The Sky Pilot  (1899) and The Prospector (1904), which, combining adventure with reli�  gious messages and wholesome sentiment, made him the best-selling  Canadian novelist of the early 20th century. His best books are considered  to be The Man from Glengarry (1901) and Glengarry School Days (1902).</p><p>Connors, Jimmy in full James Scott Connors (b.

In 1974 he won three grand-  slam tournaments (U.S. Open, Australian Open, and Wimbledon) but was  barred from the French Open because he had joined World Team Tennis.  Known for his aggressive play and fiery temper, Connors won the Wim�  bledon and U.S. doubles (with Ilie Nastase) titles in 1975, the Wimble�  don singles in 1982, and the U.S. singles in 1976, 1978, 1982, and 1983.</p><p>conodont Vko-no-.dantX Minute toothlike fossil composed of the min�  eral apatite (calcium phosphate); conodonts are among the most fre�  quently encountered fossils in marine sedimentary rocks of Paleozoic age.

Under Hernan Cortes a force of some 500 men with 16  horses conquered Mexico�s Aztec empire. A force under Pedro de Alva�  rado subsequently subdued Guatemala. Francisco Pizarro defeated the  Inca in Peru with 180 men and 37 horses; his companion Diego de Alma-  gro led an expedition to Chile. Further expeditions extended Spanish rule  over much of South America. Though renowned for their bravery, the  conquistadores remain notorious for their avarice and the destruction they  wrought on native populations and civilizations. They were soon replaced  by administrators and settlers from Spain.</p><p>Conrad I (d. Dec. 23, 918) German king (911-918). The duke of Fran�  conia and a member of the powerful Franconian dynasty known as the  Conradines, Conrad was elected king on the death of the last of the East  Frankish Carolingian rulers. His reign was a bitter struggle to maintain  the traditions of Carolingian kingship against the growing power of  Saxon, Bavarian, and Swabian dukes. Conrad failed to gain the support  of the church, and his military campaigns were unsuccessful. Unable to  establish his family as the royal house of the eastern Franks, he is reported  to have proposed his opponent, Henry of Saxony, as his successor.</p><p>Conrad II (b. c. 990�d. June 4, 1039, Utrecht, Ger.) German king  (1024-39) and emperor (1027-39), founder of the Salian (or Franconian)  dynasty. In 1016 he married a duchess to whom he was distantly related,  and the emperor Henry II used the marriage as a pretext to have him exiled.  The two men were later reconciled, and Conrad was crowned king of  Germany in 1024. A rebellion of German nobles and princes of Lombardy  collapsed (1025), and Conrad was made successively king of Italy (1026)  and emperor (1027). He instituted legislative reforms, issuing a new set  of feudal constitutions for Lombardy. His son Henry was elected king in  1028 and became his chief counselor. Conrad defeated Poland (1028),  regaining lands lost earlier. He inherited Burgundy (1034) and resolved  dissensions among the great princes in Italy (1038).</p><p>Conrad III (b. 1093�d. Feb. 15, 1152, Bamberg, Ger.) German king  (1138-52), the first of the Hohenstaufen dynasty. Nephew of Emperor  Henry V of Germany, he revolted when he was passed over as heir by the  electors, and he was crowned antiking at Niimberg (1127) and king of  Italy (1128). Returning to Germany in 1132, he fought the German king  Lothar II until 1135, when Conrad submitted and was pardoned. He  became king when Lothar died, quelling resistance in Bavaria and Sax�  ony. Conrad set out for Palestine on the Second Crusade (1147) and vis�  ited Constantinople (1148), where he cemented an alliance with Manuel I  Comnenus. Unable to visit Rome, he never received the imperial crown.</p><p>Conrad, Joseph orig. Jozef Teodor Konrad Korzeniowski</p><p>(b. Dec. 3, 1857, Berdichev, Ukraine, Russian Empire�d. Aug. 3, 1924,  Canterbury, Kent, Eng.) Polish-British novelist and short-story writer. His  father was a Polish patriot who was exiled to northern Russia, and Con�  rad was an orphan by age 12. He managed to join the French merchant  marine and in 1878 the British merchant navy, where he pursued a career  for most of the next 15 years; his naval experiences would provide the  material for most of his novels. Though he knew little English before he  was 20, he became one of the master English stylists. He is noted for tales  in rich prose of dangerous life at sea and in exotic places, settings he used  to reveal his real concern, his deeply pessimistic vision of the human  struggle. Of his many novels, which include Almayer�s Folly (1895), The  Nigger of the �Narcissus� (1897), Lord Jim (1900), Nostromo (1904), The  Secret Agent (1907), and Under Western Eyes (1911), several are regarded  as masterpieces. He also published seven story collections; the novella  �Heart of Darkness� (1902) is his most famous shorter work and the basis  for Francis Ford Coppola�s film Apocalypse Now (1979). Conrad�s influ�  ence on later novelists has been profound.</p><p>Conrad von Hotzendorf Vkon-.rat-fon-'hcet-son-.dorfV, Franz  (Xaver Josef), Count (b. Nov. 11, 1852, Penzing, Austria�d. Aug.  25, 1925, Mergentheim, Ger.) Austrian soldier. A career officer in the  Austro-Hungarian army, he became chief of staff in 1906. A conservative  propagandist for Austria-Hungary, he advocated preventive wars against  Serbia and Italy, for which he was briefly dismissed in 1911. In World  War I, he planned the successful Austro-German offensive of 1915, but  he was later hampered by German domination and lack of military  resources. He was dismissed when Charles I took command in 1916.</p><p>Conrail in full Consolidated Rail Corp. U.S. railroad company  created by the federal government in 1973 to take over six bankrupt  northeastern railroads. Conrail began operations in 1976 with major por�  tions of the Central Railroad Co. of New Jersey, Erie Lackawanna Rail�  way Co., Lehigh &amp; Hudson River Railway Co., Lehigh Valley Railroad  Co., Penn Central Transportation Co., and Reading Co. The resulting net�  work carried freight traffic to 15 states, from the Atlantic Ocean to St.  Louis, Mo., and from the Ohio River north to Canada. Its passenger traf�  fic was turned over to Amtrak and regional transportation authorities in  1983. Its stock was put up for sale to the public in 1987, and in 1999 most  of Conrail�s assets were acquired by CSX and Norfolk Southern railroads.</p><p>conscientious objector One who opposes participation in military  service, on the basis of religious, philosophical, or political belief. A fea�  ture of Western society since the beginning of the Christian era, consci�  entious objection developed as a doctrine of the Mennonites (16th  century), the Society of Friends (17th century), and others. Exemptions  may be unconditional, conditioned on alternative civilian service, or lim�  ited to combat duty. Those who refuse conscription may face imprison�  ment. Philosophical or political reasons are acceptable grounds for  exemption in many European countries, but the U.S. recognizes only  membership in a religious group that endorses pacifism.</p><p>consciousness Quality or state of being aware. As applied to the lower  animals, consciousness refers to the capacity for sensation and, usually,  simple volition. In higher animals, this capacity may also include think�  ing and emotion. In human beings, consciousness is understood to include  �meta-awareness,� an awareness that one is aware. The term also refers  broadly to the upper level of mental life of which the person is aware, as  contrasted with unconscious processes. Levels of consciousness (e.g.,  attention vs. sleep) are correlated with patterns of electrical activity in the  brain (brain waves). See also philosophy of mind.</p><p>conscription or draft Compulsory enrollment for service in a coun�  try�s armed forces. It has existed at least since the Egyptian Old King�  dom in the 27th century bc. It usually takes the form of selective service  rather than universal conscription. (The latter generally refers to compul-</p></section><section><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>consequentialism &#x25BA; conspiracy I 453</p><p>sory military service by all able-bodied men between certain ages, though  a few countries�notably Israel�have also drafted women.) In the 19th  century Prussia�s system of building up a large standing army through  conscription became the model for competing European powers. During  the American Civil War both the federal government and the Confederacy  instituted a draft, but the U.S. did not use it again until entering World  War I in 1917. Like the U.S., Britain abandoned conscription at the end  of World War I but reverted to it when World War II threatened. During  the ensuing Cold War, Britain retained the draft until 1960 and the U.S.  until 1973. See also U.S. Army.</p><p>consequentialism In ethics, the doctrine that actions should be judged  right or wrong on the basis of their consequences. The simplest form of  consequentialism is classical (or hedonistic) utilitarianism, which asserts  that an action is right or wrong according to whether it maximizes the net  balance of pleasure over pain in the universe. The consequentialism of  G.E. Moore, known as �ideal utilitarianism,� recognizes beauty and  friendship, as well as pleasure, as intrinsic goods that one�s actions should  aim to maximize. According to the �preference utilitarianism� of R.M.  Hare (1919-2002), actions are right if they maximize the satisfaction of  preferences or desires, no matter what the preferences may be for. Con-  sequentialists also differ over whether each individual action should be  judged on the basis of its consequences or whether instead general rules  of conduct should be judged in this way and individual actions judged  only by whether they accord with a general rule. The former group are  known as �act-utilitarians� and the latter as �rule-utilitarians.� See also  DEONTOLOGICAL ETHICS.</p><p>conservation Planned management of a natural resource or of a par�  ticular ecosystem to prevent exploitation, pollution, destruction, or neglect  and to ensure the future usability of the resource. Living resources are  renewable, minerals and fossil fuels are nonrenewable. In the West, con�  servation efforts date to 17th-century efforts to protect European forests  in the face of increasing demands for fuel and building materials. National  parks, first established in the 19th century, were dedicated to the preser�  vation of uncultivated land not only to provide a safe haven to wildlife  but to protect watershed areas and help ensure a clean water supply.  National legislation and international treaties and regulations aim to strike  a balance between the need for development and the need to conserve the  environment for the future.</p><p>conservation law or law of conservation In physics, the prin�  ciple that certain quantities within an isolated system do not change over  time. When a substance in an isolated system changes phase, the total  amount of mass does not change. When energy is changed from one form  to another in an isolated system, there is no change in the total amount  of energy. When a transfer of momentum occurs in an isolated system, the  total amount of momentum is conserved. The same is true for electric  charge in a system: charge lost by one particle is gained by another. Con�  servation laws make it possible to predict the macroscopic behaviour of  a system without having to consider the microscopic details of a physical  process or chemical reaction.</p><p>conservation of energy See conservation of energy</p><p>conservatism Political attitude or ideology denoting a preference for  institutions and practices that have evolved historically and are thus mani�  festations of continuity and stability. It was first expressed in the modern  era through the works of Edmund Burke in reaction to the French Revolu�  tion, which Burke believed tarnished its ideals through its excesses. Con�  servatives believe that the implementation of change should be minimal  and gradual; they appreciate history and are more realistic than idealis�  tic. Well-known conservative parties include the British Conservative  Party, the German Christian Democratic Union, the U.S. Republican Party,  and the Japanese Liberal-Democratic Party. See also Christian Democracy;</p><p>LIBERALISM.</p><p>Conservative Judaism Form of Judaism that mediates between  Reform Judaism and Orthodox Judaism. Founded in 19th-century Germany  as the Historical School, it arose among German-Jewish theologians who  advocated change but found Reform positions extreme. They accepted the  Reform emphasis on critical scholarship, but wished to maintain a stricter  observance of Jewish law (e.g., dietary laws) and continued belief in the  coming of the Messiah. In 1886, rabbis of this centrist persuasion founded  the Jewish Theological Seminary of America (New York), leading to the  development of Conservative Judaism as a religious movement.</p><p>Conservative Party (Canada) See Progressive Conservative Party  of Canada</p><p>Conservative Party officially National Union of Conserva�  tive and Unionist Associations. British political party whose guid�  ing principles include promotion of private property and enterprise,  maintenance of a strong military and foreign policy, and preservation of  traditional cultural values and institutions. It is the heir of the old Tory  Party, whose members began forming �conservative associations� after  electoral rights were extended to the middle class in 1832. The modem  party (whose members are often known as Tories) is essentially a coali�  tion of two groups, and must balance its traditionalist and communitar�  ian wing against its libertarian and individualist wing. It also experiences  internal conflict over Britain�s relationship with the European Union. Its  membership is heavily dependent on the landowning and middle classes,  but its electoral base has extended at times to incorporate about one-third  of the working class. Since World War I, it and the Labour Party have  dominated British politics.</p><p>Conservatoire des Arts et Metiers \kou-ser-va-'twar-da-'zar-za-  ma-'tya\ (French: �Conservatory of Arts and Trades�) Public institution  of higher learning in Paris, dedicated to applied science and technology,  that grants degrees primarily in engineering. It is also a laboratory that  specializes in testing, measuring, and standardization. Its third component  is a national museum of technology. It was founded by Jacques de Vau-  canson in 1794, in the former priory of St.-Martin-des-Champs, to house  his own and others� inventions; his automated loom, found there after his  death by J.-M. Jacquard, became the basis for Jacquard�s revolutionary  design. It contains numerous elaborate automatons and other mechanical  devices popular in the 18th century.</p><p>conservatory In architecture, a heavily glazed structure, frequently  attached to and directly entered from a dwelling, in which plants are pro�  tected and displayed. Unlike the greenhouse, an informal structure situ�  ated in the working area of a garden, the conservatory became a popular  19th-century decorative architectural feature proclaiming the status of its  owner. The most outstanding example is Joseph Paxton�s Crystal Palace.</p><p>conservatory In music, institution for education in musical perfor�  mance and composition. The term and institution derives from the Italian  conservatorio, which in the Renaissance period and earlier denoted an  orphanage often attached to a hospital. The children there were given  musical training; the term gradually came to apply to music schools. The  first secular school of music for students at large was established in Paris  in 1784. Throughout the 19th century the French model was copied, with  modifications, in Europe and in the U.S., later in Canada and Australia.  Conservatories typically offer instruction to people of all ages, but the  primary focus is on students age 10-25. Important U.S. conservatories  include the Curtis Institute of Music, the Eastman School, and the Juilliard  School.</p><p>consonance and dissonance Perceived qualities of musical chords  and intervals. Consonance is often described as relative �stability,� and  dissonance as �instability.� In musical contexts, certain intervals seem to  call for motion by one of the tones to �resolve� perceived dissonance.  The most consonant intervals are generally recognized as the unison and  octave, and the next most consonant interval as the perfect fifth. Conso�  nance tends to reflect the early intervals of the overtone series (which  include, in addition to the octave and perfect fifth, the major and minor  thirds and the perfect fourth), but many musical factors can affect the per�  ception of consonance and dissonance.</p><p>consonant Any speech sound characterized by an articulation in which  a closure or narrowing of the vocal tract completely or partially blocks  the flow of air; also, any letter or symbol representing such a sound. Con�  sonants are usually classified according to the place of articulation (e.g.,  palate, teeth, lips); the manner of articulation, as in stops (complete clo�  sure of the oral passage, released with a burst of air), fricatives (forcing  of breath through a constricted passage), and trills (vibration of the tip of  the tongue or the uvula); and the presence or absence of voicing, nasal�  ization, aspiration, and other features.</p><p>conspiracy Agreement between two or more persons to commit an  unlawful act or to accomplish a lawful end by unlawful means. Some U.S.  states require an overt act in addition to the agreement to constitute con�  spiracy. Individual conspirators need not even know of the existence or  the identity of all other conspirators. In a chain conspiracy the parties act</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>454 I Constable &#x25BA; Constantine I</p><p>separately and successively (as in distributing narcotics). A civil con�  spiracy is not prosecuted as a crime but forms the grounds for a lawsuit.  In antitrust law, conspiracies in restraint of trade (e.g., price fixing) are  rigorously prosecuted. In the U.S. it is common to punish a conspiracy  to commit an offense more harshly than the offense itself, but there has  been a growing trend to follow the European example and make the pun�  ishment for conspiracy the same as or less than that for the offense itself.</p><p>Constable, John (b. June 11, 1776, East Bergholt, Suffolk, Eng.�d.  March 31, 1837, London) British painter. The artist�s father was a wealthy  man who owned mills at Flatford and Dedham, on the Suffolk and Essex  banks of the Stour, respectively. Constable began his career in 1799 after  entering the Royal Academy Schools in London. In the years 1809 to 1816  he established his mastery and evolved his individual manner, concen�  trating on the scenes that had delighted him as a boy: the village lanes,  the fields and meadows running down to the Stour, barges drawn by tow  horses, and the vessels passing the locks at Flatford or Dedham. In  1813-14 he filled two sketchbooks, which survive intact, with over 200  landscape drawings. After about 1816 Constable began to embody his  concept of the Suffolk countryside in a series of canvases monumental  enough to make an impression in exhibitions of the Royal Academy; his  best-known work from this period is The Hay-Wain (1821). These works  reveal Constable�s detailed study of the formation of clouds, the colour  of meadows and trees, and the effect of light glistening on leaves and  water. Especially later in his career, he was considered a master of water�  colour as well as oil painting on canvas. He is ranked with J.M.W. Turner  as one of the greatest 19th-century British landscape painters.</p><p>Salisbury Cathedral from the Bishop's Grounds, oil on canvas by John Constable,  1823; in the Victoria and Albert Museum, London.</p><p>THE BRIDGEMAN ART UBRARY/GETTY IMAGES</p><p>Constance (b. 1154�d.

National political  rivalries divided the Council of Constance. Two of the three contending  popes were deposed; the third abdicated, and in 1417 the council selected  a new pope, Martin V.

Muslim Arabs took Egypt (642), invaded Arme�  nia (647), and defeated Constans at sea in 655. A civil war among Arabs  prevented them from attacking Constantinople, and he secured a nonag�  gression treaty with Syria (659). Within the empire he tried to force unity  on the church, forbidding debate on divisive theological questions and  exiling the pope when he objected (653). He made his son coemperor  (654) and then aroused public outrage by ordering the murder of his own  brother (660).

Passed over as suc�  cessor to the throne, he fought to make himself emperor. Victory at the  Milvian Bridge outside Rome (312) made him emperor in the West;  according to legend, a cross and the words in hoc signo vinces (�In this  sign, conquer�) appeared to him there and he forthwith adopted Chris�  tianity. In 313 he issued, with Licinius, the Edict of Milan, granting toler�  ance to Christians; he also gave land for churches and granted the church  special privileges. He opposed heresies, notably Donatism and Arianism,  and he convoked the important Council of Nicaea. After defeating and  executing Licinius, he gained control of the East and became sole  emperor. He moved the capital from Rome to Byzantium, which he  renamed Constantinople (324). In 326 he had his wife and eldest son killed  for reasons that remain obscure. He angered the Romans by refusing to  participate in a pagan rite and never entered Rome again. Under his  patronage, Christianity began its growth into a world religion.

His father-in-law, Romanus I Lecapenus, was crowned coemperor with  him in 920 and soon became the primary ruler. Shut out of government,  Constantine devoted himself to scholarship; his writings include works  on the Slavic and Turkic peoples and on Byzantine ceremonies. In 944  the sons of Romanus, impatient for power, had their father deported, and  the ensuing public outcry emboldened Constantine to banish them in 945;  he then ruled alone until his death.</p><p>Constantine IX Monomachus Xmo-'na-mo-kosX (b. c. 980�d.

An opponent of  the great military leaders, he neglected imperial defenses, instead spend�  ing extravagantly on luxuries and magnificent buildings. Rebellions broke  out at home and abroad, and Byzantine lands were threatened by invad�  ers in southern Italy, Thrace, Macedonia, and Armenia. Constantine tried  to ally with the papacy to save southern Italy from the Normans, but  growing differences between Rome and Constantinople resulted in the  Schism of 1054.</p><p>Constantine XI Palaeologus \,pa-le-'a-l3-g9s\ (b.

It promulgated the Nicene Creed and declared finally the Trinitarian doc�  trine of the equality of Father, Son, and Holy Spirit. It gave the bishop of</p><p>Constantinople honour second only to that of the pope. Only Eastern bish�  ops were summoned to the council, but the Greeks claimed that it was  ecumenical. It did come to be so regarded, though the Western church did  not accept the ranking of Constantinople as second to Rome until the 13th  century. The Second Council of Constantinople, held in 553, was called  by Justinian I; by endorsing an edict of Justinian�s, it lent support to Mono-  physitism and diminished the earlier Council of Chalcedon. The Third  Council of Constantinople, held in 680, condemned the Monothelites,  who claimed that Christ had a single will despite his two natures. The  Fourth Council of Constantinople, held in 869-870 at the suggestion of  Basil I, resulted in the excommunication of St. Photius and increased the  animosity between the Eastern and Western churches.</p><p>Constantius I Chlorus Vkon-'stan-che-os-'klor-osV orig.

Its provisions usually specify how the government is  to be organized, what rights it shall have, and what rights shall be retained  by the people. Modem constitutional ideas developed during the Enlight�  enment, when philosophers such as Thomas Hobbes, Jean-Jacques Rousseau,  and John Locke proposed that constitutional governments should be stable,  adaptable, accountable, and open, should represent the governed, and  should divide power according to its purpose.

It was more conservative than the abortive  democratic Constitution of 1793. The Constitution of 1795 established a  liberal republic with a franchise based on the payment of taxes, similar  to that of the Constitution of 1791 ; a bicameral legislature to slow down  the legislative process; and a five-man Directory.

It is the oldest written national constitution in operation, completed  in 1787 at the Constitutional Convention of 55 delegates who met in  Philadelphia, ostensibly to amend the Articles of Confederation. The Con�  stitution was ratified in June 1788, but because ratification in many states  was contingent on the promised addition of a Bill of Rights, Congress pro�  posed 12 amendments in September 1789; 10 were ratified by the states,  and their adoption was certified on Dec. 15, 1791. The framers were espe�  cially concerned with limiting the power of the government and securing  the liberty of citizens. The Constitution�s separation of the legislative,  executive, and judicial branches of government, the checks and baances  of each branch against the other, and the explicit guarantees of individual  liberty were all designed to strike a balance between authority and liberty.  Article I vests all legislative powers in the Congress �the House of Rep�  resentatives and the Senate. Article II vests executive power in the presi�  dent. Article III places judicial power in the hands of the courts. Article  IV deals, in part, with relations among the states and with the privileges  of the citizens. Article V with amendment procedure, and Article VI with  public debts and the supremacy of the Constitution. Article VII stipulates  that the Constitution would become operational after being ratified by nine  states. The 10th Amendment limits the national government�s powers to  those expressly listed in the Constitution; the states, unless otherwise  restricted, possess all the remaining (or �residual�) powers of government.  Amendments to the Constitution may be proposed by a two-thirds vote  of both houses of Congress or by a convention called by Congress on the  application of the legislatures of two-thirds of the states. (All subsequent  amendments have been initiated by Congress.) Amendments proposed by  Congress must be ratified by three-fourths of the state legislatures or by  conventions in as many states. Twenty-seven amendments have been  added to the Constitution since 1789. In addition to the Bill of Rights,  these include the 13th (1865), abolishing slavery; the 14th (1868), requir�  ing due process and equal protection under the law; the 15th (1870), guar�  anteeing the right to vote regardless of race; the 17th (1913), providing  for the direct election of U.S. senators; the 19th (1920), instituting wom�  en�s suffrage, and the 22nd (1951), limiting the presidency to two terms.

Drafted by  Emmanuel Joseph Sieyes, it disguised the true character of the military dic�  tatorship created by Napoleon, reassuring the partisans of the Revolution  by proclaiming the irrevocability of the sale of national property and by  upholding the legislation against the emigre nobility. It created the regime  known as the Consuate, which concentrated all real power in the hands  of Napoleon. Submitted to a plebiscite, it won overwhelmingly in 1800.</p><p>Constitutional Act or Canada Bill (1791) British law repealing  certain portions of the Quebec Act of 1774. The new act provided a more  democratic constitution for the area, establishing an elected legislature for  each province, the first in that part of Canada, and a governor and an  executive council appointed by the crown. Bills could originate in the  legislature, but they could be disallowed by the crown.</p><p>Constitutional Convention (May-September 1787) Assembly that  drafted the Constitution of the United States. All states but Rhode Island sent  delegates in response to a call by the Annapolis Convention for a meeting in  Philadelphia to amend the Articles of Confederation. The delegates decided  to replace the Articles with a document that strengthened the federal gov�  ernment. An important issue was the apportioning of legislative represen�  tation. Two plans were presented: the Virginia plan, favoured by the large</p><p>states, apportioned representatives by population or wealth; the New Jersey  plan, favoured by the small states, provided for equal representation for  each state. A compromise established the bicameral Congress to ensure  both equal and proportional representation. The document was approved  on September 17 and sent to the states for ratification.</p><p>Constitutional Democratic Party or Kadet Russian political  party advocating a radical change in Russian government toward a con�  stitutional monarchy like Britain�s. It was founded in October 1905 by  the Union of Liberation and other liberals associated with the zemstvos.

After the Bolsheviks seized power in 1917, the  party was outlawed and ceased to function.</p><p>Constitutional Laws of 1875 In France, a series of fundamental  laws that, taken collectively, came to be known as the constitution of the  Third Republic. It established a two-house legislature (with an indirectly  elected Senate as a conservative check on the popularly elected Chamber  of Deputies); a Council of Ministers responsible to the Chamber; and a  president with powers resembling those of a constitutional monarch. It  left untouched many aspects of the French governmental structure.</p><p>constitutional monarchy System of government in which a monarch  (see monarchy) shares power with a constitutionally organized govern�  ment.

Constructivism opposes the Platonist interpretation,  which construes mathematical statements as referring to a domain of time�  less mathematical objects existing independently of our knowledge of  them (see form, Patonism). For the constructivist, certain classically valid  forms of logical inference (e.g., the law of excluded middle, the law of  double negation, the postulation of infinite sets) may no longer be  employed unrestrictedly in constructing mathematical proofs (see logic).  The constructivist therefore recognizes fewer mathematical proofs and  theorems than does the Platonist.

In 1920  Tatlin was joined by Antoine Pevsner and Naum Gabo. Their �Realist  Manifesto,� which directed their followers to �construct art,� gave the  movement its name. The group, soon joined by Aleksandr Rodchenko and  El Lissitzky, produced abstract works reflecting modern machinery and  technology, using plastic, glass, and other industrial materials. Applying  the same principles to architecture, they spread the movement�s ideals  throughout Europe and to the U.S. after Soviet opposition dispersed the  group.

They  were nominated by the Senate and elected by the popular assembly; each  could veto the other�s decisions. As heads of state, they commanded the  army, presided over the Senate and assemblies and acted on their decrees,  and handled foreign affairs. At the end of his one-year term, a consul was  generally appointed to serve as governor of a province. The office con�  tinued in weaker form under the empire.</p><p>Consulate (1799- 1804) French government established after the Coup  of 18-19 Brumaire. The Constitution of the Year VIII created an executive  consisting of three consuls, but the First Consul, Napoleon, wielded all  real power, while the other two, Emmanuel Joseph Sieyes and Pierre-Roger  Ducos (1747-1816), were figureheads. The principles of representation  and legislative supremacy were discarded. The executive branch was  given the power to draft new laws, and the legislative branch became little  more than a rubber stamp. Elections became an elaborate charade, with  voters stripped of real power. Napoleon abolished the Consulate when he  declared himself emperor.</p><p>consumer credit Short- and intermediate-term loans used to finance  the purchase of commodities or services for personal consumption.

Installment loans, such as automobile loans  and credit-card purchases, are paid back in two or more payments; non�  installment loans, such as the service credit extended by utility compa�  nies, are paid back in a lump sum. Consumer loans usually carry a higher  rate of interest than business loans. See also credit.</p><p>consumer goods Any tangible commodity purchased by households  to satisfy their wants and needs. Consumer goods may be durable or non�  durable. Durable goods (e.g., autos, furniture, and appliances) have a sig�  nificant life span, often defined as three years or more, and consumption  is spread over this span. Nondurable goods (e.g., food, clothing, and  gasoline) are purchased for immediate or almost immediate consumption  and have a life span ranging from minutes to three years. See also pro�  ducer goods.</p><p>consumer price index (CPI) Measure of living costs based on  changes in retail prices. Consumer price iNDEXes are widely used to mea�  sure changes in the cost of maintaining a given standard of living. The  goods and services commonly purchased by the population covered are  priced periodically, and their prices are combined in proportion to their  relative importance. This set of prices is compared with the initial set of  prices collected in the base year to determine the percentage increase or  decrease. The population covered may be restricted to wage and salary  earners or to city dwellers, and special indexes may be used for special  population groups (e.g., retirees). Such indexes do not take into account  shifts over time in what the population buys; when modified to take sub�  jective preferences into account, they are called constant-utility indexes.  Consumer price indexes are available for more than 100 countries.</p><p>consumer protection Legal framework promoting customer safety  and education and providing protection from hazardous or substandard  products and from fraud. In the U.S., the Federal Trade Commission  (established 1914) and the Food and Drug Administration (established  1927) help ensure consumer protection. Regulations address manufacture  and design, advertising, labeling, and sales methods. In 1985 the UN pro�  duced its Guidelines for Consumer Protection (updated 1995); they cover  consumer safety and product standards and education, providing a frame�  work and a benchmark for governments (particularly of less developed  countries) to establish a legal basis for consumer protection.

Consumer psychologists examine the  preferences, customs, and habits of various consumer groups; their  research on consumer attitudes is often used to help design advertising  campaigns and to formulate new products.</p><p>consumerism Movement or policies aimed at regulating the products,  services, methods, and standards of manufacturers, sellers, and advertisers  in the interests of the buyer. Such regulation may be institutional, statutory,  or embodied in a voluntary code accepted by a particular industry, or it may  result more indirectly from the influence of consumer organizations. Gov�  ernments often establish formal regulatory agencies to ensure consumer  protection (in the U.S., e.g., the Federal Trade Commission and the Food  and Drug Administration). Some of the earliest consumer-protection laws  were created to prevent the sale of tainted food and harmful drugs. The U.S.  consumer protection movement gained strength in the 1960s and �70s as  consumer activists led by Ralph Nader lobbied for laws setting safety stan�  dards for automobiles, toys, and numerous household products. Consumer  advocates have also won passage of laws obliging advertisers to represent  their goods truthfully and preventing sales representatives from using  deceptive sales tactics. Consumer advocacy is carried on worldwide by the  International Organization of Consumers Unions (IOCU).</p><p>consumer's surplus In economics, the difference between the total  amount consumers would be willing to pay to consume the quantity of  goods transacted on the market and the amount they actually have to pay  for those goods. The former is generally interpreted as the monetary value  of consumer satisfaction. The concept was developed in 1844 by the  French civil engineer Arsene-Jules-Etienne-Juvenal Dupuit (1804-1866)  and popularized by Alfred Marshall. Though economists adopted a non-  quantifiable approach to consumer satisfaction in the 20th century, the  concept is used extensively in the fields of welfare economics and taxation.</p><p>consumption In economics, the final using up of goods and services.  The term excludes the use of intermediate products in the production of  other goods (e.g., the purchase of buildings and machinery by a business).</p><p>Economists use statistical information on income and purchases to trace  trends in consumption, seeking to map consumer demand for goods and  services. In classical economics, consumers are assumed to be rational and  to allocate expenditures in such a way as to maximize total satisfaction  from all purchases. Incomes and prices are seen as consumption�s two  major determinants. Critics of the model point out that there are many  exceptions to rational consumer behaviour�for example, the phenom�  enon of conspicuous consumption, in which the high price of a product  increases its prestige and adds to demand.</p><p>consumption See tuberculosis</p><p>consumption tax Levy such as an excise tax, a sales tax, or a tariff  paid directly or indirectly by the consumer. Consumption taxes fall more  heavily on lower-income than on upper-income groups because people  with less money consume a larger proportion of their income than those  with more money. See also progressive tax, regressive tax.</p><p>contact lens Thin artificial lens worn on the surface of the eye to correct  refractive defects of vision. Early glass contact lenses, invented in 1887,  were uncomfortable and could not be worn long. Plastic-based lenses,  made to measurements of corneal curvature taken by optical instruments,  were first developed in the mid 20th century. Gas-permeable lenses allow  more oxygen to reach the eye, thus increasing comfort and wear time.  Contact lenses have advantages over eyeglasses for certain visual defects  and may be preferred for the sake of appearance and other reasons.</p><p>containership Oceangoing vessel designed to transport large,  standard-sized containers of freight. Rail-and-road containers were used  early in the 20th century; in the 1960s containerization became a major  element in ocean shipping as well. Containerships, which are large and  fast, carry containers above deck as well as below, and their cargoes can  be loaded and unloaded rapidly.</p><p>containment Strategic U.S. foreign policy of the late 1940s and early  1950s intended to check the expansionist designs of the Soviet Union  through economic, military, diplomatic, and political means. It was con�  ceived by George Kennan soon after World War II. An early application  of containment was the Truman Doctrine (1947), which guaranteed U.S.  aid to �free peoples� resisting �armed subjugation� by communist forces.  See also Marshall Plan.</p><p>contempt In law, willful disobedience to or open disrespect of a court,  judge, or legislative body. An act of disobedience to a court order may  be treated as either criminal or civil contempt; sanctions for the latter end  upon compliance with the order. An act or language that consists solely  of an affront to a court or interferes with the conduct of its business con�  stitutes criminal contempt; such contempt carries sanctions designed to  punish as well as to coerce compliance. In the U.S., a congressional com�  mittee can compel the attendance of witnesses. Any witness failing to  appear or otherwise obstructing the committee in the course of exercis�  ing its powers may be in contempt. Witnesses are, however, protected by  the 5th Amendment against forced self-incrimination. See also perjury.</p><p>Conti family French branch of the House of Bourbon. The title of prince  of Conti, created in the 16th century, was revived in favor of Armand de  Bourbon, prince de Conti (1629-1666), who was a leader in the Fronde.  He was the younger brother and rival of the prince de Conde (�the Great  Conde�). Notable members of the Conti family include Frangois-Louis de  Bourbon, prince de Conti (1664-1709), who was a candidate for the Pol�  ish throne; and Louis-Frangois de Bourbon, prince de Conti (1717-1776),  who served in the War of the Austrian Succession. The House of Conti  became extinct with the death of Louis-Frangois-Joseph de Bourbon,  prince de Conti (1734-1814), who had distinguished himself in the Seven  Years� War.</p><p>continent One of seven large continuous masses of land: Asia, Africa,  North America, South America, Antarctica, Europe, and Australia (listed  in order of size). Europe and Asia are sometimes considered a single con�  tinent, Eurasia. The continents vary greatly in size and in ratio of coastline  to total area. More than two-thirds of the world�s continental land area lies  north of the equator, and all the continents except Antarctica are wedge-  shaped, wider in the north than in the south. See also continental drift.</p><p>Continental Congress Body of delegates that acted for the Ameri�  can colonies and states during and after the American Revolution. The First  Continental Congress, meeting in Philadelphia in September 1774, was  called by the colonial Committees of Correspondence. The delegates</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>458 I Continental Divide &#x25BA; continuity principle</p><p>adopted a declaration of personal rights, denounced taxation without rep�  resentation, petitioned the British crown for a redress of grievances, and  called for a boycott of British goods. The Second Continental Congress,  meeting in May 1775, appointed George Washington commander in chief  of the army. It later approved the Declaration of Independence (1776) and  prepared the Articles of Confederation (1781), which granted certain pow�  ers to the Congress.</p><p>Continental Divide Most notable watershed of the North American  continent. The mountains comprising it extend generally north-south, thus  dividing the continent�s principal drainage into waters flowing eastward  (e.g., into Hudson Bay in Canada or the Mississippi River in the U.S.) and  waters flowing westward (into the Pacific Ocean). Most of the divide runs  along the crest of the Rocky Mountains, through British Columbia in  Canada and through the states of Montana, Wyoming, Colorado, and New  Mexico in the U.S. Its central point is Colorado, where it has many peaks  above 13,000 ft (3,962 m). It continues southward into Mexico, roughly  paralleling the Sierra Madre, and into Central America.</p><p>continental drift Large-scale movements of continents over the course  of geologic time. The first complete theory of continental drift was pro�  posed in 1912 by Alfred Wegener, who postulated that a single supercon�  tinent, which he called Pangea, fragmented late in the Triassic Period (248-  206 million years ago) and that the parts began to move away from one  another. He pointed to the similarity of rock strata in the Americas and  Africa as evidence to support his hypothesis. Wegener�s ideas received  support from the concepts of seafloor spreading and plate tectonics begin�  ning in the 1960s. The modern theory states that the Americas were joined  with Europe and Africa until c. 190 million years ago, when they split  apart along what is now the Mid-Atlantic Ridge. Subsequent tectonic plate  movements brought the continents to their present positions.</p><p>The theory of continental drift is based on the concept that the continental and oce�  anic crusts are embedded in the uppermost layer of the rocky lithosphere. The lithos�  phere is divided into sections called tectonic plates, which slide over an underlying  partly molten layer of rock called the asthenosphere. New lithosphere is created at  diverging plate margins (e.g., midocean ridges), and old lithosphere is consumed at  converging margins (e.g., subduction zones). The continents passively "drift" along  with the moving plates, and over hundreds of millions of years this movement alters  the entire geography of the Earth.</p><p>� MERRIAM-WEBSTER INC.</p><p>Continental philosophy Collective term for the many distinct  philospohical traditions, methods, and styles that predominated on the  European continent (particularly in France and Germany) from the time  of Immanuel Kant. It is usually understood in contrast with analytic philoso�  phy, also called Anglo-American philosophy. In the 20th century it encom�  passed schools such as phenomenology, existentialism, structuralism, and  deconstruction and thinkers such as Martin Heidegger, Jean-Paul Sartre,  Maurice Merleau-Ponty, Michel Foucault, and Jacques Derrida. See also  structuralism; poststructuralism.</p><p>continental shelf Broad, relatively shallow submarine platform that  forms a border to a continent, typically extending from the coast to depths  of 330-660 ft (100-200 m). Continental shelves average about 40 mi (65  km) in width. Almost everywhere they are simply a continuation of the  continental landmass: narrow, rough, and steep off mountainous coasts  but broad and comparatively level offshore from plains. Continental  shelves are usually covered with a layer of sand, silts, and silty muds.  Their surfaces feature small hills and ridges that alternate with shallow  depressions and valley-like troughs. In a few cases, steep-walled V-shaped  submarine canyons cut deeply into both the shelf and the slope below.  See illustration above.</p><p>coastal  shoreline plain</p><p>submarine</p><p>canyon</p><p>continental</p><p>continental</p><p>slope</p><p>continental</p><p>shelf</p><p>abyssal</p><p>plain</p><p>The broad, gentle pitch of the continental shelf gives way to the relatively steep con�  tinental slope. The more gradual transition to the abyssal plain is a sediment-filled  region called the continental rise. The continental shelf, slope, and rise are collec�  tively called the continental margin. Depth is exaggerated here for effect.</p><p>� ENCYCLOPEDIA BRITANNICA, INC.</p><p>continental shield Any of the large stable areas of low relief (little  variation in elevations) in the Earth�s crust that are composed of Precam-  brian crystalline rocks. These rocks are always more than 570 million  years old, and some are as old as 2-3 billion years. Continental shields  occur on each of the continents.</p><p>continental slope Seaward border of a continental shelf. The world�s  combined continental slope is about 200,000 mi (300,000 km) long and  descends at an average angle of about 4� from the edge of the continen�  tal shelf to the beginning of the ocean basins at depths of 330-10,500 ft  (100-3,200 m). The slope is most gradual off stable coasts without major  rivers and is steepest off coasts with young mountain ranges and narrow  continental shelves. Slopes off mountainous coastlines and narrow shelves  commonly have outcrops of rock. The dominant sediments of continen�  tal slopes are muds; there are smaller amounts of sediments of sand or  gravel.</p><p>Continental System In the Napoleonic Wars, the blockade designed  by Napoleon to paralyze Britain through the destruction of British com�  merce. In the Decrees of Berlin (1806) and Milan (1807), France pro�  claimed that neutrals and French allies were not to trade with the British.  The United Kingdom responded with a counterblockade, which led indi�  rectly to the War of 1812. Because of Britain�s naval superiority, the  effort to enforce the system proved disastrous for Napoleon.</p><p>continuing education or adult education Any form of learning  provided for adults. In the U.S. the University of Wisconsin was the first  academic institution to offer such programs (1904). Empire College of  the State University of New York was the first to be devoted exclusively to  adult learning (1969). Continuing education includes such diverse meth�  ods as independent study; broadcast, videotape, online, and other forms  of distance learning; group discussion and study circles; conferences,  seminars, and workshops; and full- or part-time classroom study. Reme�  dial programs, such as high-school equivalency and basic literacy pro�  grams, are common. In recent years the variety of subject matter has  expanded greatly to include such topics as auto repair, retirement plan�  ning, and computer skills. See also Chautauqua movement.</p><p>continuity In mathematics, a property of functions and their graphs. A  continuous function is one whose graph has no breaks, gaps, or jumps. It  is defined using the concept of a limit. Specifically, a function is said to  be continuous at a value x if the limit of the function exists there and is  equal to the function�s value at that point. When this condition holds true  for all real number values of x in an interval, the result is a graph that can  be drawn over that interval without lifting the pencil. Such functions are  crucial to the theory of calculus, not just because they model most physi�  cal systems but because the theorems that lead to the derivative and the  integral assume the continuity of the functions involved.</p><p>continuity principle or continuity equation Principle of fluid  mechanics. Stated simply, what flows into a defined volume in a defined  time, minus what flows out of that volume in that time, must accumulate  in that volume. If the sign of the accumulation is negative, then the mate-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>continuo &#x25BA; conversion disorder I 459</p><p>rial in that volume is being depleted. The principle is a consequence of  the law of conservation of mass. The behaviour of fluids in motion is fully  described by this equation, plus a second equation, based on the second  of Newton's laws of motion, and a third equation, based on the conser�  vation of ENERGY.</p><p>continuo or basso continuo In Baroque music, a special subgroup  of an instrumental ensemble. It consists of two instruments reading the  same part: a bass instrument, such as a cello or bassoon, and a chordal  instrument, most often a harpsichord but sometimes an organ or lute. Its  appearance in the early 17th century reflected the radically new musical  texture of accompanied melody that was especially typical of the new  vocal genre of opera. The continuo (which has a counterpart in the bass  and rhythm guitar of a rock band) came to be employed in virtually all  ensemble music of the Baroque era.</p><p>contra Member of a counterrevolutionary force that sought to overthrow  Nicaragua�s left-wing Sandinista government. The original contras had  been National Guardsmen during the regime of Anastasio Somoza (see  Somoza family). The U.S. Central Intelligence Agency played a key role in  training and funding the group, whose tactics were decried by the inter�  national human-rights community. In 1984 the U.S. Congress banned  military aid to the contras; the efforts of the administration of U.S. presi�  dent Ronald Reagan to circumvent the ban led to the Iran-Contra Affair.  A general peace in the region was negotiated by Costa Rican president  Oscar Arias SAnchez, and in 1990 Nicaraquan president Violeta Chamorro  negotiated the contras� demobilization. See also Daniel Ortega.</p><p>contraception Birth control by prevention of conception or impreg�  nation. The most common method is sterilization. The most effective tem�  porary methods are nearly 99% effective if used consistently and correctly.  Many methods carry health risks; barrier devices and avoidance of inter�  course during the most fertile period are safest. Hormonal contraceptives  use estrogen and/or progesterone to inhibit ovulation. The �morning-after  pill� (high-dose hormones) is effective even after intercourse. The most  serious side effect of oral contraceptives is the risk of blood-clotting dis�  orders. Intrauterine devices (IUDs) are placed inside the uterus and appear  to cause a mild endometrial inflammation that either inhibits fertilization  or prevents a fertilized egg from implanting. Certain types were taken off  the market in the 1970s and �80s when it was found that their side effects  included a high incidence of pelvic inflammatory disease, ectopic pregnancy,  and spontaneous septic abortion. Barrier devices, such as condoms, dia�  phragms, cervical caps, female condoms (vaginal pouches), and vaginal  sponges, prevent sperm from entering the uterus. Condoms also prevent  sexually transmitted disease. Used with spermicides, condoms are nearly  100% effective. Fertility awareness techniques have evolved from keep�  ing track of the menstrual cycle (the so-called �rhythm method�; see men�  struation) to avoid intercourse around the time of ovulation; tracking body  temperature and cervical mucus consistency can raise effectiveness to  more than 80%. Experimental forms of birth control include an oral con�  traceptive for men.</p><p>contract Agreement between two or more parties that creates for each  party a duty to do something (e.g., to provide goods at a certain price  according to a specified schedule) or a duty not to do something (e.g., to  divulge an employer�s trade secrets or financial status to third parties). A  party�s failure to honour a contract allows the other party or parties to  bring an action for damages in a court of law, though arbitration may also  be pursued in an effort to keep the matter confidential. In order to be valid,  a contract must be entered into both willingly and freely. A contract that  violates this principle, including one made with a legal minor or a per�  son deemed mentally incompetent, may be declared unenforceable. A  contract also must have a lawful objective.</p><p>contralto See alto</p><p>contrast medium Substance comparatively opaque to X-rays, which  appears lighter on X-ray film and allows a body structure that does not  normally contrast with its background to be seen clearly on the film.  Common contrast media include barium sulfate and iodized organic com�  pounds. They are given by the route that introduces them into the struc�  ture to be examined�swallowed or as an enema for the digestive tract,  inhaled for the respiratory tract, or injected for blood vessels and for  organs and tissues they supply. Serious reactions to contrast media are not  infrequent.

On  its march to Mexico City, the U.S. force under Winfield Scott was blocked  by a Mexican force and detoured via a difficult road across lava beds held  by another Mexican force. After an engagement that lasted less than 20  minutes, Scott�s troops gained control of several roads to Mexico City.  They then captured the main Mexican army of Antonio Santa Anna at  Churubusco.</p><p>contributory negligence In law, behaviour that contributes to one�s  own injury or loss and fails to meet the standard of prudence that one  should observe for one�s own good. Contributory negligence of the plain�  tiff is frequently pleaded in defense to a charge of negligence. In Engish  law and in the law of many U.S. states, if the plaintiff is shown to have  contributed through negligence to his own injury, recovery may still be  allowed, but provision is made for an equitable reduction of damages.  Contributory negligence has been criticized by some authorities because  it effectively excuses one party (the defendant) even though both were  negligent.</p><p>control system Means by which a set of variable quantities is held  constant or caused to vary in a prescribed way. Control systems are inti�  mately related to the concept of automation but have an ancient history.  Roman engineers maintained water levels in aqueducts by means of float�  ing valves that opened and closed at appropriate levels. James Watt�s fly-  ball governor (1769) regulated steam flow to a steam engine to maintain  constant engine speed despite a changing load. In World War II, control-  system theory was applied to anti-aircraft batteries and fire-control sys�  tems. The introduction of analog and digital computers opened the way  for much greater complexity in automatic control theory. See also Jac�  quard LOOM, PNEUMATIC DEVICE, SERVOMECHANISM.</p><p>control theory Field of applied mathematics relevant to the control of  certain physical processes and systems. It became a field in its own right  in the late 1950s and early �60s. After World War II, problems arising in  engineering and economics were recognized as variants of problems in dif�  ferential equations and in the calculus of variations, though they were not  covered by existing theories. Special modifications of classical techniques  and theories were devised to solve individual problems, until it was rec�  ognized that these seemingly diverse problems all had the same math�  ematical structure, and control theory emerged. See also control system.</p><p>convection Process by which heat is transferred by movement of a  heated fluid such as air or water. Most fluids expand when heated. They  become less dense and more buoyant, and so rise. The heated molecules  eventually cool, become more dense, and sink. This repeated process sets  up convection currents that account for the uniform heating of the air in  a room or water in a kettle. Air convection can be forced by a fan, and  water convection by a pump. Atmospheric convection currents can be set  up by local heating effects such as solar radiation or contact with cold  surfaces. Such currents are usually vertical and account for atmospheric  phenomena such as clouds and thunderstorms.</p><p>convection See mass flow</p><p>Convention, National See National Convention</p><p>convention, political See political convention</p><p>convergence Mathematical property of infinite series, integrals on  unbounded regions, and certain sequences of numbers. An infinite series  is convergent if the sum of its terms is finite. The series Vi + l A + Vs + Vi6  + Via. + ... sums to 1 and thus is convergent. The harmonic series 1 + Vi  + l A + l A + Vs + ... does not converge. An integral calculated over an inter�  val of infinite width, called an improper integral, describes a region that  is unbounded in at least one direction. If such an integral converges, the  unbounded region it describes has finite area. A sequence of numbers  converges to a particular number when the difference between successive  terms becomes arbitrarily small. The sequence 0.9, 0.99, 0.999, etc., con�  verges to 1.</p><p>conversion disorder formerly hysteria In psychology, a neurosis  marked by extreme emotional excitability and disturbances of psychic,  sensory, vasomotor, and visceral functions. The earlier concept of hyste�  ria was used frequently in the first half of the 20th century to explain a  wide variety of symptoms and behaviours observed particularly in  women. (The term hysteria derives from the Greek word for womb,  reflecting the Greeks� belief that the condition resulted from disturbances</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>460 I conveyor belt &#x25BA; Coolidge</p><p>of the uterus.)

Conveyor belts are used in industrial  applications and also on large farms, in warehousing and freight-handling,  and in movement of raw materials. Belt conveyors of fabric, rubber, plas�  tic, leather, or metal are driven by a power-operated roll mounted under�  neath or at one end of the conveyor. The belt forms a continuous loop and  is supported either on rollers (for heavy loads) or on a metal slider pan  (if loads are light enough to prevent frictional drag on the belt). Motors  operating through constant- or variable-speed reduction gears usually pro�  vide the power.</p><p>convolvulus See bindweed</p><p>convoy Vessels sailing under the protection of an armed escort. Since  the 17th century, neutral powers have claimed the right of convoy in war�  time, providing warships to escort their merchantmen and keep them  secure from search or seizure. In World War I the British organized trans�  atlantic convoys protected by a cordon of warships; the same system pro�  tected Allied shipping from German submarines during the Battle of the  Atlantic in World War II. During the Iran-Iraq War (1980-90), oil tank�  ers transiting the Strait of Hormuz into and out of the Persian Gulf were  escorted by warships of the U.S. and other Western navies.</p><p>Conway, Thomas (b.

Conway advocated Washington�s replacement as  commander in chief by Horatio Gates; his �plot,� called the Conway  Cabal, was exposed, and he was forced to resign.</p><p>cony or coney Any of certain unrelated animals, including two mam�  mals and two fishes. One mammalian cony is more commonly called a  pika. The name cony was once applied to the rabbit and is still sometimes  used in the fur business to indicate rabbit fur.

Feb. 14, 1779, Kealakekua Bay,  Hawaii) British sailor and explorer. He joined the Royal Navy (1755) and  in 1763-67 surveyed the St. Lawrence River and the coast of Newfound�  land. In 1768 he was appointed commander of the first scientific expe�  dition to the Pacific. Sailing on the HMS Endeavour , he found and charted  all of New Zealand and explored the eastern coast of Australia. That voy�  age (1768-71) produced a wealth of scientifically collected material and  was also notable for Cook�s successful prevention of scurvy among crew  members. Promoted to commander, he was sent with two ships to make  the first circumnavigation and penetration into the Antarctic. On that expe�  dition (1772-75), which ranks as one of the greatest of all sailing-ship  voyages, he successfully completed the first west-east circumnavigation  in high latitudes. On a third voyage (1776-79) in search of a Northwest  Passage around Canada and Alaska, he was killed by Polynesian natives  on Hawaii.</p><p>Cook, Mt.

He began to arrange excursions on  a regular basis, and in 1856 he led his first grand tour of Europe. In the  early 1860s he became an agent for the sale of travel tickets; with his son,  John Mason Cook (1834-99), he founded the Thomas Cook &amp; Son travel  agency. In the 1880s the firm also organized military transport and postal  services.</p><p>Cook Inlet Inlet, Gulf of Alaska in the northern Pacific Ocean.

Located roughly 2,000 mi (3,000 km) northeast of New Zealand,</p><p>the 15 islands, scattered from north to south over some 900 mi (1,450  km) of ocean, are divided into a southern group of nine islands, includ�  ing Raratonga (the seat of government), and a northern group of six. All  in the northern group are true atolls; most in the southern group have vol�  canic interiors. They were probably settled by Polynesians from Tonga  and Samoa; there is evidence of a highly organized society c. ad 1100.  Capt. James Cook explored many of them during the 1770s.

With Irving Langmuir, he also developed the first suc�  cessful submarine-detection system.</p><p>cooling system Apparatus used to keep the temperature of a structure  or device from exceeding limits imposed by needs of safety and efficiency.  In a mechanical transmission, the oil loses its lubricating capacity if over�  heated; in a hydraulic coupling or converter, the fluid leaks under the  pressure created. In an electric motor, overheating causes deterioration of  the insulation. In an overheated internal-combustion engine, the pistons  may seize in the cylinders. The cooling agents customarily employed are  air and a liquid (usually water), either alone or in combination. In some  cases, direct contact with ambient air (free convection) may be sufficient,  as in cooling towers; in other cases, it may be necessary to employ forced  convection, created either by a fan or by the natural motion of the hot  body. Cooling systems are used in automobiles, industrial plant machin�  ery, nuclear reactors, and many other types of machinery.

In 1445 Copenhagen was made the capital and the residence of the  royal family. Its palaces include Amalienborg, home to the Danish mon-  archs, and Christiansborg, now housing Parliament. Tivoli amusement  park is a popular attraction. Copenhagen is one of Europe�s leading cul�  tural and educational centres; its oldest university was founded in 1479.  Historically a trade and shipping hub, it has also become an industrial  city. Shipbuilding, machinery production, and canning and brewing are  among the chief manufacturing activities.</p><p>Copenhagen, Battle of (April 2, 1801) British naval victory over  Denmark in the Napoleonic Wars. The armed-neutrality treaty of 1794  between Denmark and Sweden, to which Russia and Prussia adhered in  1800, was considered a hostile act by England. In 1801 a detachment of  the British navy was sent to Copenhagen. After a fierce battle in the har�  bor, Adm.

Having the Sun in this central position explained the apparent  motion of planets relative to the fixed stars and was truer than the Earth-  centred Ptolemaic system (see Ptolemy). Scientifically, the Copernican sys�  tem led to belief in a much larger universe than before (because, if the  Earth revolved around the Sun, the stars would have to be very distant  not to appeal - to alter their position); more broadly, the Copernican prin�  ciple is invoked to argue against any theory that would give the solar sys�  tem a special place in the universe. Dethronement of Earth from the centre  of the universe caused profound shock: the Copernican system challenged  the entire system of ancient authority and required a complete change in  the philosophical conception of the universe.</p><p>Copernicus Vka-'psr-ni-kssV Nicolaus Polish Mikotaj Kopernik</p><p>(b.

Elected a canon of the cathedral of  Frauenburg in 1497, he took advantage of his financial security to begin  his astronomical observations. His publication in 1543 of Six Books Con�  cerning the Revolutions of the Heavenly Orbs marked a landmark of  Western thought (see Copernican system). Copernicus had first conceived  of his revolutionary model decades earlier but delayed publication  because, while it explained the retrograde motion of the planets (and  resolved their order), it raised new problems that had to be explained,  required verification of old observations, and had to be presented in a way  that would not provoke the religious authorities.

Nov. 14, 1900, Brooklyn, N.Y.,  U.S.�d. Dec. 2, 1990, North Tarrytown, N.Y.) U.S. composer. Bom to  Russian-Jewish immigrant parents, he studied composition in Paris with  Nadia Boulanger. In his early works he experimented with jazz rhythms  and then with an abstract style influenced by Neoclassicism. After the  mid-1930s he was concerned with making music accessible to a wider  audience and adopted notably American traits in his compositions.  Famously public-spirited and generous, he came to be unofficially  regarded as the U.S.�s national composer. He is best known for his three  ballets based on American folk material: Billy the Kid (1938), Rodeo  (1942), and Appalachian Spring (1944, Pulitzer Prize). He also wrote film  scores, orchestral works, and operas. In his later years Copland refined  his treatment of Americana, making his references less overt, and he pro�  duced a number of works using the experimental technique of SERIALISM.  He continued to lecture and to conduct through the mid-1980s.</p><p>Copley, John Singleton (b. July 3, 1738, Boston, Mass.�d. Sept. 9,  1815, London, Eng.)

He was famous for  his portraits d�apparat, portrayals of his subjects with the objects asso�  ciated with them in their daily lives or professions. In 1775 he settled in  London and turned to the more fashionable history painting; he was  elected to the Royal Academy in 1779. He revealed a gift for portraying  heroic action in multifigure compositions. He is considered the greatest  U.S. painter of the 18th century and the finest artist of the colonial era.</p><p>copper Metallic chemical element, one of the transition elements, chemi�  cal symbol Cu, atomic number 29.</p><p>Sometimes found in the free state in  nature, it is a reddish metal, very duc�  tile and an unusually good conduc�  tor of electricity and heat. Most of  the world�s copper production is  used by the electrical industries; the  remainder is combined with other  metals (e.g., zinc, tin, nickel) to form  alloys such as brass, bronze, nickel  silver, and Monel. Copper is part of  nearly all coinage metals. In com�  pounds copper usually has valence 1  (cuprous) or 2 (cupric). Cuprous  compounds include cuprous oxide, a  red pigment and a fungicide; cuprous  chloride, a catalyst for certain  organic reactions; and cuprous sulfide, with a variety of uses. Cupric  compounds include cupric oxide, a pigment, decolorizing agent, and cata�  lyst; cupric chloride, a catalyst, wood preservative, mordant, disinfectant,  feed additive, and pigment; and cupric sulfate, a pesticide, germicide, feed  additive, and soil additive. Copper is a necessary trace element in the  human diet and essential to plant growth; in blue-blooded mollusks and  crustaceans it plays the same role in hemocyanin as iron does in hemo�  globin.</p><p>copper (butterfly) Any member of the butterfly subfamily Lycaeninae  (family Lycaenidae). Coppers are common and widely distributed. Adults,  sometimes known as gossamer-winged butterflies, are delicate, with a  wingspan of 0.75-1.5 in. (18-38 mm). They are rapid fliers, usually with  iridescent wings. Coppers typically range from orange-red to brown, usu�  ally with a copper tinge and dark markings. Copper larvae feed on clo�  ver, dock, or sorrel.</p><p>Copper Age First part of the Bronze Age. The beginning of the period  is sometimes called the Chalcolithic (Copper-Stone) Age (c. 8000 bc),  referring to the initial use of copper ore. Sometime after 6000 bc, smelt�  ing ore to produce pure copper was discovered in Anatolia (Turkey). From  5000 bc copper metallurgy, with cast tools and weapons, was a factor</p><p>leading to urbanization in Egypt and Mesopotamia. Copper metallurgy  spread to India by 3500 bc and to Europe and China by 3000 bc. Copper  ore occasionally contains tin, which makes dating bronze metallurgy dif�  ficult. The Bronze Age began c. 3500 bc in the Middle East and spread  throughout the Old World between 3000 and 1800 bc. The Copper Age  began in the New World c. ad 100 and the Bronze Age c. 1000.</p><p>Copperhead Term used during the American Civil War to describe a  Northerner who opposed the war policy and favoured a negotiated settle�  ment with the South.

Atolls  are circular reefs without a central landmass. Patch reefs have irregular  tablelike or pinnacle features. Smaller patches occur inside atoll lagoons;  larger patches occur as isolated parts of any of the other three reef cat�  egories, and they sometimes occur completely separate from other kinds  of reefs.</p><p>Coral Sea Part of the South Pacific Ocean. It is located between Queens�  land, Australia, on the west and Vanuatu and New Caledonia on the east,  and bordered on the north by Papua New Guinea and the Solomon Islands.  Occupying an area of 1,849,800 sq mi (4,791,000 sq km), it merges with  the Tasman Sea and Solomon Sea and is connected to the Arafura Sea via  the Torres Strait. It was named for its many coral formations, including  the Great Barrier Reef. During World War II it was the scene of a strategic  U.S. naval and air victory over the Japanese (1942).</p><p>coral snake Any of about 90 species of strongly patterned burrowing  elapids. �True� forms are limited to the New World, chiefly the tropics, but  similar species live in Asia and Africa. Secretive and docile, coral snakes  rarely bite when handled, but the venom of some can kill a person. Most  prey on other snakes. More than 50 species in the largest genus, Micru-  rus, range from the southern U.S. to Argentina. They are ringed with red,  black, and yellow or white. The eastern coral snake, or harlequin snake  {Micrurus fulvius), ranges from North Carolina and Missouri in the U.S.  to northeastern Mexico and is about 30 in. (76 cm) long, with wide bands</p><p>of red and black separated by yellow. The rhyme �Red on yellow, dan�  gerous fellow� distinguishes it from similarly coloured but harmless spe�  cies.</p><p>Coralli, Jean orig. Giovanni Coralli Peracini (b. Jan. 15, 1779,  Paris, France�d. May 1, 1854, Paris) French dancer and choreographer.  He made his debut at the Paris Opera in 1802. His appointment as ballet  master at the Opera (1831-50) coincided with the most brilliant phase of  the Romantic ballet. In 1841 Coralli began to work with the ballerina Car-  lotta Grisi in Giselle, now regarded as a classic. Although attributed solely  to Coralli, most of its principal action was arranged by Jules Perrot. The  choreography of La Peri (1843), however, was entirely Coralli�s.</p><p>corbel Vkor-boA Block or brick partially embedded in a wall, with one  end projecting out from the face. The weight of added masonry above  counterbalances the cantilever and keeps the block from falling out of the  wall. Corbeling often occurs over several courses, with each block or brick  overhanging the one below so as to resemble a set of inverted steps. The  form may be continuous, as in a corbeled arch, or a series of separate  brackets, as on a medieval battlement. Corbeling was used extensively  before the development of true arches and vaults.</p><p>Corbusier, Le See Le Corbusier</p><p>Corday (d'Armont) \kor-'de\, (Marie-Anne-) Charlotte (b.

Leadership later fell to Jacques-Rene Hebert  and others, who helped overthrow the Girondins and gave the club a more  radical tone. It fell into oblivion after Hebert�s execution in 1794.</p><p>Cordilleran \ 1 kor-d 3 l- , yer-3n\ Geosyncline Linear trough in the  Earth�s crust in which rocks of Late Precambrian to Mesozoic Age  (roughly 600-65 million years ago) were deposited along the western  coast of North America. The principal mountain-building phases of the  geosyncline took place during Mesozoic time, but many earlier events  have also been recorded. Deformation of the Cordilleran Geosyncline and  the formation of the Cordilleran fold belt appear to have been related to  the development of oceanic trenches along the western margins of the  North American continent.</p><p>Cordoba Vkor-th6-ba\ City (pop., 1999 est.: 1,275,585), the second  largest in Argentina. It lies on the Primero River along the foothills of the  Sierra de Cordoba. Founded in 1573, its location between the coast and  the interior settlements favoured its early development. In 1599 Jesuits  settled in the city and founded the country�s first university (1613). Cor�  doba�s growth was stimulated by the completion of rail connections with  the east in 1869 and the San Roque Dam in 1866, which provides irri�  gation water for orchards and grain fields and hydroelectric power for the  city�s many factories.</p><p>Cordoba or Cordova Vkor-d3-v9\ ancient Corduba City (pop.,  2001: 308,072), capital of Cordoba province, southern Spain.

It declined under the Visigoths (6th-8th  centuries ad), and it was captured by the Muslims in 711. Abd al-Rahman  I, of the Umayyad family, made it his capital in 756 and founded the Great  Mosque of Cordoba, which still stands. By the 10th century it was the larg�  est city in Europe, filled with palaces and mosques. It fell to the Castilian  king Ferdinand III in 1236 and became part of Christian Spain.

The alloy compo�  sition is mainly iron with small amounts of nickel. This composition is  deduced from the chemistry of iron meteorites that presumably came from  the breakup of a planetary body that also had an iron core.

He stud�  ied in Bologna before settling in Rome. He became widely known as a  violinist, director, and teacher, and he lived with his family at the palaces  of Cardinals Pamphili and Ottoboni. His many students included  Francesco Geminiani (1687-1762) and Pietro Locatelli (1695-1764). As  a violinist, he had considerable influence on the development of violin  style. As the first composer whose fame was based exclusively on his  nonvocal music, his reputation rests mainly on his sonatas and his 12  Concerti Grossi, which established the concerto grosso form. He wrote  four sets of 12 trio sonatas each (1681-95), a set of 12 solo sonatas (1700),  and the concerti grossi (1714). Long after his death, his works were widely  studied and imitated for their classic poise and serenity. With his music  the ideal of full-blown tonality first became securely established.</p><p>coreopsis \,kor-e-'ap-s3s\ Any ornamental summer-blooming plant of  the genus Coreopsis, commonly known as tickseed, in the composite fam�  ily, consisting of about 100 species of annual and perennial herbaceous  plants native to North America. Members have flower heads with yellow  disk flowers and yellow, pink, white, or variegated ray flowers. The heads  are solitary or in branched clusters, and some varieties have double flow�  ers. Golden coreopsis (C. tinctoria) is a popular garden plant; swamp  tickseed (C. rosea ) is grown in wildflower gardens.</p><p>Corfu \k6r-'fii\ Greek Kerkira Vker-ke-ra\ One of the Ionian Islands,  northwestern Greece. With adjacent small islands, it forms the Corfu  department (pop., 1995 est.: 108,000) of Greece; the town of Corfu (pop.,  1995 est.: 36,000) is the departmental capital. Corfu occupies 229 sq mi  (593 sq km). It was settled by the Corinthians c. 734 bc. Off its coast the  first naval battle in Greek history was fought, between Corfu and Corinth  c. 664 bc. About 435 bc it sought the aid of Athens against Corinth, pre�  cipitating the Peloponnesian War. A Roman possession in 229 bc, it later  passed to the Byzantines, then to the Normans. It was ruled by Venice  from 1386 to 1797 and was under British administration from 1815 until  it was ceded to Greece in 1864. Germans and Italians occupied it during</p><p>World War II. It is now a popular tourist destination and produces olive  oil, figs, oranges, lemons, and wine.</p><p>Corfu incident (1923) Brief occupation of the Greek island of Corfu  by Italian forces. In August 1923 Italians forming part of an international  boundary delegation were murdered on Greek soil, leading Benito Mus�  solini to order a naval bombardment of Corfu. After the Greeks appealed  to the League of Nations, the Italians were ordered to evacuate but Greece  was forced to pay Italy an indemnity.</p><p>coriander or cilantro Feathery annual herb ( Coriandrum sativum ) of  the parsley family, and its dried fruit, native to the Mediterranean and  Middle East. The seeds go by the name coriander; they have a mild, fra�  grant aroma and aromatic taste and are used to flavour many foods. The  delicate young leaves�known in the U.S. by their Spanish name,  cilantro�are widely used in Latin American, Indian, and Chinese dishes.</p><p>Corinth Vk6r-anth\ Greek Korinthos Vk6r-en-th6s\ Ancient city of the  Peloponnese, Greece. Located on the Gulf of Corinth, the site was occu�  pied before 3000 bc but developed as a commercial centre only in the 8th  century bc. In the late 6th century bc, it was outstripped by Athens. Occu�  pied in 338 bc by Philip II, it was destroyed in 146 bc by Rome. In 44 bc  Julius Caesar reestablished Corinth as a Roman colony; the New Testa�  ment includes the letters addressed to its Christian community by St. Paul.  It declined in the later Middle Ages; its ruins are near the modem city of  Corinth.</p><p>Corinth, League of Alliance established at Corinth in 337 bc. It com�  prised the ancient Greek states except Sparta, and was led by Philip II of  Macedonia. Delegates, elected in proportion to their state�s military  power, decided federal policies. The league declared war on Persia, but  under Alexander the Great it contributed little to the war effort. Its major  act was to condemn the Thebans to slavery and distribute their lands  among other states following revolts in 336 and 335. It was disbanded  after Alexander�s death (323).</p><p>Corinth \ko-'rint\, Lovis (b. July 21, 1858, Tapiau, East Prussia�d.  July 12, 1925, Zandvoort, Neth.) German painter and graphic artist. He  trained in Paris with the painter William Bouguereau. In 1902 he settled in  Berlin and, with Max Liebermann, became a leading exponent of Impres�  sionism in Germany. After recovering from a stroke in 1911, his style  became much looser and more powerfully Expressionist. He was best  known for his landscapes and portraits, including numerous powerfully  expressive self-portraits, and he produced many etchings and lithographs  (e.g., Apocalypse, 1921).</p><p>Coriolanus \,k6r-e-9-'la-n3s\, Gnaeus Marcius Legendary Roman  hero. He is said to have lived in the late 6th and early 5th century bc and  to have owed his surname to his courage at the siege of Corioli (493 bc)  in the war against the Volsci. For trying to have the office of tribune abol�  ished during a famine in Rome, he was sent into exile. Taking refuge with  the king of the Volsci, he led the Volscian army against Rome but turned  back in response to pleas from his family. He is the subject of William  Shakespeare�s play Coriolanus.</p><p>Coriolis \,kor-e-'o-bs\ force Apparent force that must be included if  Newton's laws of motion are to be used in a rotating system. First  described by Gustave-Gaspard Coriolis (1792-1843) in 1835, the force  acts to the right of the direction of body motion for counterclockwise  rotation and to the left for clockwise rotation. On Earth an object that  moves along a north-south path, or longitudinal line, will be apparently  deflected to the right in the Northern Hemisphere and to the left in the  Southern Hemisphere. The deflection is related to the motion of the object,  the motion of the Earth, and latitude. The Coriolis effect is important in  meteorology and oceanography as well as ballistics; it also has great sig�  nificance in ASTROPHYSICS.</p><p>Cork Seaport city (pop., 2002 prelim.: 123,338), southwestern Ireland.  The seat of County Cork, it is situated on Cork Harbour at the mouth of  the River Lee. Founded as a monastery in the 7th century, it was often  raided and was eventually settled by the Danes. It passed to Henry II of  England in 1172. The city was taken by Parliamentarian forces under  Oliver Cromwell (1649) and by the duke of Marlborough (1690). It was  heavily damaged in 1920 during the Irish uprising against England. Its  industries include leatherworking, brewing, and distilling.</p><p>cork Outer bark of the evergreen cork oak ( Quercus suber ), native to the  Mediterranean.

In the Orient and elsewhere, these  glossy black underwater swimmers have been tamed for fishing. Their  guano is valued as a fertilizer. Cormorants live on seacoasts, lakes, and  some rivers, nesting on cliffs or in bushes or trees. They have a long,  hook-tipped bill, patches of bare skin on the face, and a small throat pouch  (gular sac). The most widespread species is the common, or great, cor�  morant (Phalacrocorax carbo), which grows up to 40 in.

It originated in the New World and has been introduced glo�  bally. American Indians taught colonists to grow corn, including some  varieties of yellow com that are still popular as food, as well as varieties  with red, blue, pink, and black kernels, often banded, spotted, or striped,  that today are regarded as ornamental and in the U.S. are called Indian  com. The tall, annual grass has a stout, erect, solid stem and large nar�  row leaves with wavy margins. Corn is used as livestock feed, as human  food, and as raw material in industry. Though it is a major food in many  parts of the world, it is inferior to other cereals in nutritional value. Ined�  ible parts of the plant are used in industry�stalks for paper and wall-  board; husks for filling material; cobs for fuel, to make charcoal, and in  the preparation of industrial solvents. Corn husks also have a long his�  tory of use in the folk arts for objects such as woven amulets and corn-  husk dolls. Corn is one of the most widely distributed of the world�s food  plants.

Appointed governor of Nueva Galicia in west-central Mexico,  Coronado was sent north with a large force to locate and capture the leg�  endary Seven Cities of Cibola, reported to be fabulously wealthy. He was  disillusioned to discover instead the Zuni pueblos of New Mexico and a  seminomadic Indian tribe in Kansas. Though the treasure he sought eluded  him, his explorers were the first Europeans to view the Grand Canyon,  and he extended Spanish territory over huge areas of North America. His  expedition�s failure led to his indictment on his return to Mexico, but he  was acquitted.</p><p>coronary bypass Surgical treatment for coronary heart disease to  relieve angina pectoris and prevent heart attacks. It became widely used  in the 1960s. One or more blood vessels�usually an artery in the chest  or a vein from the leg�are transplanted to create new paths for blood to  flow from the aorta to the heart muscle, bypassing obstructed sections of  the coronary arteries.</p><p>coronary heart disease or ischemic \is-'ke-mik\ heart dis�  ease Progressive reduction of blood supply to the heart muscle due to  narrowing or blocking of a coronary artery (see atherosclerosis). Short�  term oxygen deprivation can cause angina pectoris. Long-term, severe  oxygen depletion causes a heart attack. Coronary bypass or angioplasty is  needed if medication and diet do not control the disease.</p><p>coroner Public official whose principal duty is to inquire into any death  that appears to be unnatural. The name of the office as it emerged in  England in the late 12th century was originally �crowner� (also called  �coronator�), a reference to the coroner�s principal duty of protecting the  crown�s property. By the late 19th century, the coroner�s role had shifted  to that of conducting inquests into unnatural deaths. In Canada, all coro�  ners are appointed. In the U.S., the office is elective or appointive, depend�  ing on the jurisdiction. Coroners often possess both legal and medical  qualifications, but the office is sometimes filled by laypersons, including  undertakers, sheriffs, and justices of the peace. In many states the office  has been replaced by that of the medical examiner, who is usually a  licensed pathologist.</p><p>Corot \k6-'r6\, (Jean-Baptiste-) Camille (b. July 16, 1796, Paris,  Fr.�d. Feb. 22, 1875, Paris) French landscape painter. Born to prosper�  ous parents, he proved unsuited to the family business and at age 25 was  given a small allowance to pursue art training. He traveled frequently and  painted topographical landscapes throughout his career, but he preferred  making small oil sketches and drawings from nature; from these he pro�  duced large finished paintings for exhibition. By the 1850s he had  achieved critical success and a large income, and he was generous to less  successful artists. His naturalistic oil sketches are now more highly  regarded than his more self-consciously poetic finished paintings. He is  often associated with the Barbizon school. A master of tonal gradation and  soft edges, he prepared the way for the Impressionist landscape painters  and had an important influence on Claude Monet, Camille Pissarro, and  Berthe Morisot.</p><p>corporal punishment Infliction of physical pain upon a person�s  body as punishment for a crime or infraction. Such penalties include beat�  ing, branding, mutilation, blinding, and the use of the stock and pillory.  The term also denotes the physical disciplining of children in the schools  and at home. From ancient times through the 18th century, corporal pun�  ishment was commonly used in instances that did not call for capital pun�  ishment, ostracism, or exile. But the growth of humanitarian ideals during  the Enlightenment and afterward led to its gradual abandonment, and  today it has been almost entirely replaced in the West by imprisonment  or other nonviolent penalties. Several international conventions on human  rights prohibit it. Beatings and other corporeal punishments continue to  be administered in the prison systems of many countries. Whipping and  even amputation remain prescribed punishments in some Middle Eastern  and Asian societies. Corporal punishment of schoolchildren is still sanc�  tioned in many states.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>468 i corporate finance &#x25BA; corruption</p><p>corporate finance Acquisition and allocation of a corporation�s funds  or resources, with the goal of maximizing shareholder wealth (i.e., stock  value). Funds are acquired from both internal and external sources at the  lowest possible cost and may be obtained through equity (e.g., sale of  stock) or debt (e.g., bonds, bank loans). Resource allocation is the invest�  ment of funds; these investments fall into the categories of current assets  (such as cash and inventory) and fixed assets (such as real estate and  machinery). Corporate finance must balance the needs of employees, cus�  tomers, and suppliers against the interests of the shareholders. See also  BUSINESS FINANCE.</p><p>corporate income tax Tax imposed by public authorities on the  incomes of corporations. Virtually all countries assess taxes on the net  profits of corporations; most are flat-rate levies rather than extensively  graduated taxes. A corporate income tax was adopted by the U.S. gov�  ernment in 1909; three-fourths of the states also levy corporate income  taxes. See also capital gains tax; income tax.</p><p>corporation Specific legal form of organization of persons and mate�  rial resources, chartered by the state, for the purpose of conducting busi�  ness. As contrasted with the other two major forms of business ownership,  the sole proprietorship and the partnership, the corporation has several  characteristics that make it a more flexible instrument for large-scale eco�  nomic activity. Chief among these are limited liability, transferability of  shares (rights in the enterprise may be transferred readily from one inves�  tor to another without constituting legal reorganization), juridical person�  ality (the corporation itself as a Active �person� has legal standing and  may thus sue and be sued, make contracts, and hold property), and indefi�  nite duration (the life of the corporation may extend beyond the partici�  pation of any of its founders). Its owners are the shareholders, who  purchase with their investment a share in the proceeds of the enterprise  and who are nominally entitled to a measure of control over its financial  management. Direct shareholder control became increasingly impossible  in the 20th century, however, as the largest corporations came to have  tens of thousands of shareholders. The practice of proxy voting by man�  agement was legalized and adopted as a remedy, and today salaried man�  agers exercise strong control over the corporation and its assets. See also  MULTINATIONAL corporation.</p><p>Corporation for Public Broadcasting See PBS</p><p>corporatism Theory and practice of organizing the whole of society  into corporate entities subordinate to the state. According to the theory,  employers and employees would be organized into industrial and profes�  sional corporations serving as organs of political representation and  largely controlling the people and activities within their jurisdiction. Its  chief spokesman was Adam Muller (b. 1779�d. 1829), court philosopher  to the FOrst (prince) von Metternich, who conceived of a �class state� in  which the classes operated as guilds, or corporations, each controlling a  specific function of social life. This idea found favour in central Europe  after the French Revolution, but it was not put into practice until Benito  Mussolini came to power in Italy; its implementation there had barely  begun by the start of World War II, which resulted in his fall. After World  War II, the governments of many democratic western European countries  (e.g., Austria, Norway, and Sweden) developed strong corporatist ele�  ments in an attempt to mediate and reduce conflict between businesses  and trade unions and to enhance economic growth.</p><p>Corpus Christi City (pop., 2000: 277,454) and port on Corpus Christi  Bay, southern Texas, U.S. Founded in 1839 as a trading post, it was the  scene of Mexican War operations and American Civil War skirmishes. The  arrival of the railroad in 1881 stimulated a land boom. The exploitation  of gas (1923), development of a deepwater port (1926), and discovery of  the Saxtet oil field (1939) laid the city�s economic foundation. Resort  facilities are based on the bay and the coastal barrier islands, including  Padre Island. It is also the site of the Corpus Christi Naval Air Station.</p><p>Corpus Christi Bay Inlet, Gulf of Mexico, southern Texas, U.S. Form�  ing a deepwater harbour for the port of Corpus Christi, it is 25 mi (40 km)  long and 3-10 mi (5-16 km) wide and is sheltered on the east by Mus�  tang Island. Its shipping serves the petroleum, chemical, and agricultural  industries. The area is popular for sportfishing, waterfowl hunting, and  boating. The bay was entered on the feast of Corpus Christi in 1519 by  Alonso de Pineda, who claimed the region for Spain.</p><p>Correggio \ko-'re-jo\ orig. Antonio Allegri (b. August 1494, Cor�  reggio, Modena�d. March 5, 1534, Correggio) Italian painter. He stud�</p><p>ied the work of Andrea Mantegna in  Mantua and was influenced by  Leonardo da Vinci. On a visit to Rome  he was inspired by the Vatican fres�  coes of Michelangelo and Raphael. By  1518 he was in Parma, the scene of  his greatest activity. His first large-  scale commission there was the ceil�  ing decoration of the Camera di San  Paolo, in the convent of St. Paul (c.</p><p>1518-19). His fresco in the dome of  Parma Cathedral (c. 1525-30) fea�  tures the dramatic illusionistic style  that influenced dome painting in the  Baroque period. His use of bold fore�  shortening, his brilliant, highly origi�  nal approach to colour and light, and  the exquisite grace of his figures  established him as one of the most  inventive artists of the High Renais�  sance.</p><p>correlation In statistics, the  degree of association between two  random variables. The correlation  between the graphs of two data sets  is the degree to which they resemble  each other. However, correlation is  not the same as causation, and even  a very close correlation may be no  more than a coincidence. Mathemati�  cally, a correlation is expressed by a  correlation coefficient that ranges  from -1 (never occur together),  through 0 (absolutely independent),  to 1 (always occur together).</p><p>Correll, Charles See Freeman Gosden and Charles Correll</p><p>Correns \'kor-ens\, Carl Erich (b.

In the same year  as Erich Tschermak von Seysenegg and Hugo de Vries (1900), he indepen�  dently rediscovered Gregor Mendel�s paper outlining the principles of  heredity. He conducted research with garden peas, from which he drew  the same conclusions Mendel had. He helped provide the overwhelming  body of evidence in support of Mendel�s thesis, anticipating Thomas Hunt  Morgan�s development of the concept of linkage when he developed a  theory of a physical coupling of genetic factors to account for the con�  sistent inheritance of certain traits together.

He also produced well-known studies on cirrhosis of the lung (1838), aor�  titis as a cause of angina pectoris (1837), and mitral stenosis (1838).  Eponyms such as Corrigan�s respiration (shallow breathing in fever) and  Corrigan�s pulse (a jerking pulse beat) came into general use as a result  of his investigations.</p><p>corrosion Wearing away due to chemical reactions, mainly oxidation  (see oxidation-reduction, oxide). It occurs whenever a gas or liquid chemi�  cally attacks an exposed surface, often a metal, and is accelerated by warm  temperatures and by acids and salts. Normally, corrosion products (e.g.,  rust, patina) stay on the surface and protect it. Removing these deposits  reexposes the surface, and corrosion continues. Some materials resist cor�  rosion naturally; others can be treated to protect them (e.g., by coating,  painting, galvanizing, or anodizing).</p><p>corruption Improper and usually unlawful conduct intended to secure  a benefit for oneself or another. Its forms include bribery, extortion, and  the misuse of inside information. It exists where there is community indif�  ference or a lack of enforcement policies. In societies with a culture of  ritualized gift giving, the line between acceptable and unacceptable gifts  is often hard to draw.

It dates  to at least c. 2000 bc, when it was worn as an outer garment by men as  well as women in Minoan Crete. In the 16th-17th century it was worn to  flatten the chest and was reinforced with wood. Some outer corsets were  jeweled and elaborately embroidered. After 1660 they were shaped to  accentuate the breasts. In the 19th century the corset, now reinforced with  whalebone or metal, changed with the style of dresses; over-tight lacing  of corsets was blamed for numerous health problems. The corset was  abandoned in the 1920s, when looser-fitting, straight clothes came into  fashion, and in the 1930s it was replaced by the brassiere and girdle, made  of elastic materials, and by the one-piece corselette.</p><p>Corsica Vkor-si-k9\ French Corse Island (pop., 1999: 260,196) in the  Mediterranean Sea and an administrative region of France. The fourth  largest island in the Mediterranean, it has an area of 3,352 sq mi (8,681  sq km). While remains of human occupation date from at least the 3rd  millennium bc, recorded history begins c. 560 bc, when Greeks from Asia  Minor founded a town there. Taken by the Romans in the 3rd-2nd cen�  turies bc, it, together with Sardinia, became a prosperous Roman prov�  ince. Conquered later by several peoples, including Byzantines and Arabs,  it was granted to Pisa in the 11th century ad. Later ruled mainly by Genoa  through the mid-18th century, in 1768 it became a province of France. It  was the birthplace of Napoleon.

The Cortes developed in the Middle Ages when elected represen�  tatives of the free municipalities acquired the right to take part in the  affairs of the Curia Regis (�King�s Court�). They were admitted because  the crown was short of funds and lacked the right to raise taxes without  the consent of the municipalities. Cortes were established in Leon and  Castile by the early 13th century and soon appeared in Catalonia (1218),  Aragon (1274), Valencia (1283), and Navarra (1300). Today the term  refers to the national legislatures of Spain and Portugal.</p><p>Cortes \kor-'tez\, Hernan later marques del Valle de Oaxaca</p><p>(b. 1485, Medellin, near Merida, Extremadura, Castile�d. Dec. 2, 1547,  Castilleja de la Cuesta, near Sevilla) Spanish conquistador who won  Mexico for Spain. Cortes left Spain for the New World at age 19, joining  Diego Velazquez de Cuellar (b. 1465�d. 1524) in the conquest of Cuba  (1511). In 1519, with 508 men and 16 horses, he burned his ships on  Mexico�s southeastern coast, thus committing himself to conquest. After  accumulating thousands of Indian allies who resented Aztec domination,  he forged ahead to Tenochtitlan, the Aztec capital (today Mexico City).  The emperor Montezuma II, believing Cortes to be the god Quetzalcoatl,  welcomed him but was taken prisoner. Hearing that a Spanish force from  Cuba was coming to relieve him of command, Cortes left Tenochtitlan  under the command of a captain and set out to defeat his Spanish oppo�  nents. Returning with the opposition forces now under his command, he  discovered that the city had revolted; he led his troops away by night in  a costly retreat, but he returned in 1521 to conquer the city and with it</p><p>the empire.

Cortical cells may contain stored food or  other substances, such as resins, latex, essential oils, and tannins. Cortical  cells in herbaceous stems, young woody stems, and stems of succulents  contain chloroplasts and can therefore make food by photosynthesis. Food,  usually in the form of starch, in edible roots, bulbs, and tubers is stored  mostly in the cortex.</p><p>cortisone Steroid hormone produced by the adrenal cortex (see adrenal  gland). It participates in the regulation of the conversion of proteins to  carbohydrates, and to some extent it regulates salt metabolism.

Rich  deposits occur in India, Russia, Zimbabwe, and South Africa. In addition  to being a precious gem, corundum is used as an abrasive for grinding  optical glass and for polishing metals and has also been made into sand�  papers and grinding wheels.

They disappeared as a class after the shift  to steam power in the mid-19th century, but in World War II the term was  applied to small armed vessels that served as escorts for convoys. Mod�  em corvettes, usually displacing 500-1,000 tons (454-900 metric tons)  and armed with missiles, torpedoes, and machine guns, perform antisub�  marine, antiaircraft, and coastal-patrol duties in small navies.</p><p>Cory bant \'kor-3- l bant\ In Oriental and Greco-Roman mythology, any  of the wild, half-demonic beings who were attendants of the Great Mother  of the Gods.

The son of Giovanni de� Medici,  Cosimo became head of the Florentine republic in 1537 after the assas�  sination of his distant cousin Alessandro de� Medici. He continued Alessan�  dro�s tyrannical rule and defeated attempts to oust him with aid from  Emperor Charles V. Seeking to expand his power, he attacked Siena in  1554 and brought nearly all of Tuscany under his control. He used his  despotic power to improve the government�s efficiency and to sponsor  artistic projects. Far advanced for the time as an administrator, he united  all public services into one building, the Uffizi (�Offices�), designed by  Giorgio Vasari. He promoted the talents of such artists as II Bronzino and  Bartolommeo Ammannati, sponsored archaeological excavations of Etrus�  can sites, and established the Florentine Academy for linguistic studies.  In 1569 he was given the title of grand duke of Tuscany.</p><p>Cosimo, Piero di See Piero di Cosimo  Cosimo the Elder See Cosimo de� Medici  cosine See trigonometric function</p><p>Cosmati \'kaz-,ma-te\ work Type of decorative inlay or mosaic used  by Roman decorators and architects in the 12th�13th centuries.

The term derives from  craftsmen of several families named Cosmatus.</p><p>cosmetics Any of several preparations (excluding soap) applied to the  human body for beautifying, preserving, or altering the appearance or for  cleansing, colouring, conditioning, or protecting the skin, hair, nails, lips,  eyes, or teeth. The earliest known cosmetics were in use in Egypt in the  4th millennium bc. Cosmetics were in wide use in the Roman Empire, but  they disappeared from much of Europe with the fall of the Roman Empire  (5th century ad) and did not reappear until the Middle Ages, when Cru�  saders returned from the Middle East with cosmetics and perfumes. By the  18th century they had come into use by nearly all social classes. Modem  cosmetics include skin-care preparations; foundation, face powder and  rouge (blusher); eye makeup; lipstick; shampoo; hair curling and straight�  ening preparations; hair colours, dyes, and bleaches; and nail polish.  Related products include antiperspirants, mouthwashes, depilatories,  astringents, and bath crystals.</p><p>cosmic background radiation Electromagnetic radiation, mostly in  the microwave range, believed to be the highly redshifted residual effect  (see redshift) of the explosion billions of years ago from which, accord�  ing to the big-bang model, the universe was created. It was discovered by  accident in 1964 by Robert W. Wilson and Arno Penzias; its presence sup�  ports the predictions of big-bang cosmology.</p><p>cosmic ray High-speed particle (atomic nucleus or electron) that trav�  els through the Milky Way Galaxy. Some cosmic rays originate from the  Sun, but most come from outside the solar system. Primary cosmic rays  that reach Earth�s atmosphere collide with nuclei in it, creating secondar�  ies. Because lower-energy primaries are strongly influenced by the inter�  planetary magnetic field and Earth�s magnetic field (see geomagnetic field),  most of those detected near Earth have very high energy, corresponding  to speeds about 87% that of light or more. Observations from spacecraft  indicate that most cosmic rays come from the Galaxy�s disk, but the  highest-energy ones are probably extragalactic. Details of their produc�  tion and acceleration remain unclear, but apparently expanding shock  waves from supernovas can accelerate particles. From the early 1930s to  the 1950s, cosmic rays were the only source of high-energy particles used  in studying the atomic nucleus and its components. Short-lived subatomic  particles were discovered through cosmic-ray collisions, leading to the rise  of particle physics. Even powerful particle accelerators cannot impart energy  anywhere near that of the highest-energy cosmic rays. See also Victor  Francis Hess.</p><p>cosmogony See creation myth</p><p>cosmological argument Form of argument used in natural theology  to prove the existence of God. Thomas Aquinas, in his Summa theologiae,  presented two versions of the cosmological argument: the first-cause argu�</p><p>ment and the argument from contingency. The first-cause argument begins  with the fact that there is change in the world, and a change is always the  effect of some cause or causes. Each cause is itself the effect of a further  cause or set of causes; this chain moves in a series that either never ends  or is completed by a first cause, which must be of a radically different  nature in that it is not itself caused. Such a first cause is an important  aspect, though not the entirety, of what Christianity means by God. The  argument from contingency follows by another route a similar basic  movement of thought from the nature of the world to its ultimate ground.</p><p>cosmological constant Term reluctantly added by Albert Einstein to  his equations of general relativity in order to obtain a solution to the equa�  tions that described a static universe, as he believed it to be at the time.  The constant has the effect of a repulsive force that acts against the gravi�  tational attraction of matter in the universe. When Einstein heard of the  evidence that the universe is expanding, he called the introduction of the  cosmological constant the �biggest blunder� of his life. Recent develop�  ments suggest that in the early universe there may well have been a cos�  mological constant with a nonzero value.</p><p>cosmology Field of study that brings together the natural sciences,  especially astronomy and physics, in an effort to understand the physical  universe as a unified whole. The first great age of scientific cosmology  began in Greece in the 6th century bc, when the Pythagoreans introduced  the concept of a spherical Earth and, unlike the Babylonians and Egyp�  tians, hypothesized that the heavenly bodies moved according to the har�  monious relations of natural laws. Their thought culminated in the  Ptolemaic model (see Ptolemy) of the universe (2nd century ad). The  Copernican revolution (see Copernican system) of the 16th century ush�  ered in the second great age. The third began in the early 20th century,  with the formulation of special relativity and its development into general  relativity by Albert Einstein. The basic assumptions of modern cosmology  are that the universe is homogeneous in space (on the average, all places  are alike at any time) and that the laws of physics are the same every�  where.</p><p>cosmonaut See astronaut</p><p>cosmos Vkaz-m3s\ Any of the garden plants that make up the genus  Cosmos (composite family), containing about 20 species native to the tropi�  cal New World.

The term (from the Turkic kazak, �free person�) originally  referred to semi-independent Tatar groups, which formed in the Dnieper  River region. Later it was also applied to peasants who had fled from  serfdom in Poland, Lithuania, and Muscovy to the Dnieper and Don  regions. The Cossacks had a tradition of independence and received privi�  leges from the Russian government in return for military services. They  were used as defenders of the Russian frontier and advance guards for  imperial territorial expansion. Attempts in the 17th�18th century to reduce  their privileges caused revolts, led by Stenka Razin and Yemelyan Pugachov,  and the Cossacks gradually lost their autonomous status.</p><p>cost Monetary value of goods and services that producers and consum�  ers purchase. In a basic economic sense, cost is the measure of the alter�  native opportunities forgone in the choice of one good or activity over  others (see opportunity cost). For consumers, cost describes the price paid  for goods and services. For producers, cost has to do with the relation�  ship between the value of production inputs and the level of output. Total  cost refers to all the expenses incurred in reaching a particular level of  output; if total cost is divided by the quantity produced, average or unit  cost is obtained. A portion of the total cost known as fixed cost (e.g., the  costs of building rental or of heavy machinery) does not vary with the  quantity produced and, in the short run, cannot be altered by increasing  or decreasing production. Variable costs, like the costs of labour or raw  materials, change with the level of output. Economic decisions are based  on marginal cost, the additional cost of an incremental unit of production  or consumption.</p><p>cost of living Monetary cost of maintaining a particular standard of  living, usually measured by calculating the average cost of a number of  goods and services.

Costa Rica�s Pacific coast rises  abruptly into central highlands and a volcanic mountain chain that forms  the backbone of the country and descends gradually to the Caribbean  coastal plain. The climate ranges from temperate to tropical, and the wide  variety of plants and animals include species found in both North America  and South America. The developing market economy is largely based on  coffee and banana exports. Sugar is another significant cash crop, and beef  is also important. Costa Rica is a multiparty republic with one legislative  house; the head of state and government is the president. Christopher  Columbus landed in what is now Costa Rica in 1502, in an area inhabited  by a number of small independent Indian tribes. These peoples were not  easily dominated by European adventurers who followed, and it took  almost 60 years for the Spaniards to establish a permanent settlement  there. Ignored by the Spanish crown because of its lack of mineral wealth,  the colony grew slowly. Coffee exports and the construction of a rail line  improved its economy in the 19th century. It joined the short-lived Mexi�  can Empire in 1821, was a member of the United Provinces of Central  America (1823-38), and adopted a constitution in 1871. In 1890 Costa  Ricans held what is considered the first free and honest election in Cen�  tral America, beginning a tradition of democracy for which Costa Rica is  renowned. In 1987 President Oscar Arias Sanchez was awarded the Nobel  Prize for Peace for his Central American peace plan. In the early 21st  century many Costa Ricans looked to increasingly free trade with the  United States as a solution to the country�s economic woes.</p><p>Costa-Gavras \ 1 kos-t9- , gav-r9s\ / Constantine orig.

The procedure was first proposed  in 1844 by Arsene-Jules-Etienne-Juvenal Dupuit (1804-66). It was not  seriously applied until the 1936 U.S. Flood Control Act, which required  that the benefits of flood-control projects exceed their costs. A cost-benefit  ratio is determined by dividing the projected benefits of a program by the  projected costs. A wide range of variables, including nonquantitative ones  such as quality of life, are often considered because the value of the ben�  efits may be indirect or projected far into the future.</p><p>Costello, Lou See Abbott and Costello  Cotabato River See Mindanao River  Cotan, Juan Sanchez See Juan Sanchez Cotan</p><p>Cote d'Azur \,k6t-da-'zfiir\ Region bordering the Mediterranean Sea,  southeastern France.

Cote d�Ivoire can be divided into  four major regions: a narrow coastal region, an equatorial rainforest in the  west, a cultivated forest zone in the east, and a savanna region in the north.  Agriculture employs about half of the workforce. The country is a major  producer of cocoa and coffee; other exports include bananas, cotton, rub�  ber, timber, and diamonds. It is a republic with one legislative house; its  chief of state and government is the president, assisted by the prime min�  ister. European powers came to the area to trade in ivory and slaves  beginning in the 15th century, and local kingdoms gave way to French  influence in the 19th century. The French colony of Cote d�Ivoire was  founded in 1893, and full French occupation took place in 1908-18. In  1946 it became a territory in the French Union; in 1947 the northern part  of the country separated and became part of Upper Volta (now Burkina  Faso). Cote d�Ivoire peacefully achieved autonomy in 1958 and indepen�  dence in 1960, when Felix Houphouet-Boigny was elected president.

The shrubby  plants produce creamy white flow�  ers, followed by small green seed-  pods (cotton bolls), which contain  the seeds. Fibres growing from the  outer skin of the seeds become  tightly packed within the boll, which  bursts open at maturity to reveal soft  masses of the white to yellowish  white fibres. Cotton is harvested  when the bolls open. One of the  world�s leading agricultural crops,  cotton is plentiful and economically  produced, making cotton products  relatively inexpensive. The fibres  can be made into a diverse array of  fabrics suitable for a great variety of  apparel, home furnishings, and  industrial uses. Cotton fabrics can be  extremely durable and are comfortable to wear. Nonwoven cotton, made  by fusing or bonding the fibres, is useful for making disposable products  including towels, polishing cloths, tea bags, tablecloths, bandages, and  disposable uniforms and sheets for hospital and other medical uses.</p><p>Cotton, John (b.

From  1612 to 1633 he served as a vicar in Lincolnshire. When English church  authorities filed charges against him for his Nonconformism, he sailed for  New England in 1633. As �teacher� of the First Church of Boston (1633�  52), he became an influential leader of the Massachusetts Bay Colony. He  wrote a widely used children�s catechism and defended Puritan orthodoxy  in such books as The Way of the Churches of Christ in New England  (1645).

The  mechanization of spinning in England had created a greatly expanded  market for U.S. cotton, but production was bottlenecked by the manual  removal of the seeds from the raw fibre. The cotton gin pulled the cotton  through a set of wire teeth mounted on a revolving cylinder, the fibre  passing through narrow slots in an iron breastwork too small to permit  passage of the seed. The simplicity of the invention caused it to be widely  copied. It is credited with making cotton the most important export crop  of the U.S. before the American Civil War, as settlers and their slaves  spread westward through prime cotton-growing regions of South Caro�  lina, Georgia, Alabama, Mississippi, and Texas.</p><p>cottonmouth moccasin See water moccasin</p><p>cottonwood Any of several fast-growing North American trees of the  genus Populus.

After serving as a  military engineer in the West Indies,  he returned to France in the 1780s to  pursue scientific research. To inves�  tigate Joseph Priestley�s law of electri�  cal repulsions, he invented a  sensitive instrument to measure the  electrical forces involved. A light  rod made of an insulator, with a  small conducting sphere at each end,  was suspended horizontally by a fine  wire so that it was free to twist when  another charged sphere was brought  close to it. By measuring the angle  through which the rod twisted. Cou�  lomb could measure the repulsive  forces. He is best known for formu�  lating Coulomb's law. He also did  research on friction of machinery, on  windmills, and on the elasticity of metal and silk fibres.

In  England the title of earl is the equivalent of count and ranks above a VIS�  COUNT. The wife of a count or earl is a countess. The Roman comes  (�count�) was originally a household companion of the emperor; under  the Franks he was a local commander and judge. The counts were later  incorporated into the feudal structure, some becoming subordinate to  dukes, though a few countships were as great as duchies. As royal author�  ity was reasserted over the feudatories, which took place at different times  in the different kingdoms, the counts lost their political authority, though  they retained their privileges as members of the nobility.</p><p>Counter-Reformation or Catholic Reformation In Roman  Catholicism, efforts in the 16th and early 17th century to oppose the Prot�  estant Reformation and reform the Catholic Church. Early efforts grew out  of criticism of the worldliness and corruption of the papacy and clergy  during the Renaissance. Paul III (r. 1534-49) was the first pope to respond,  convening the important Council of Trent (1545-63), which reacted to  Protestant teachings on faith, grace, and the sacraments, and attempted to  reform training for the priesthood. The Roman Inquisition was established  in 1542 to control heresy within Catholic territories, and the Jesuits under  Ignatius de Loyola undertook educational and missionary work aimed at  conversion or reconversion. Emperors Charles V and Philip II took military  action against Protestant growth. Later popes of the Counter-Reformation  included Pius V, Gregory XIII, and Sjxtus V. Sts. Charles Borromeo, Philip  Neri, John of the Cross, Teresa of Avila, Francis de Sales, and Vincent de  Paul were among the most influential reforming figures.</p><p>counterfeiting Crime of making an unauthorized imitation of a genu�  ine article, typically money, with the intent to deceive or defraud. Because  of the value conferred on money and the high level of technical skill  required to imitate it, counterfeiting is singled out from other acts of  forgery. It is generally punished as a felony (see felony and misdemeanour).  The international police organization Interpol was established primarily to  organize law-enforcement efforts against counterfeiting. Software, credit  cards, designer clothing, and watches are among nonmoney items com�  monly counterfeited.</p><p>counterglow See gegenschein</p><p>counterpoint Art of combining different melodic lines in a musical  composition. The term is often used interchangeably with polyphony  (music consisting of two or more distinct melodic lines), but counterpoint  more specifically refers to the compositional technique involved in the  handling of these melodic lines. The first recorded use of two melodic  lines simultaneously was in 9th-century treatises showing examples of  organum (a type of music for multiple voices), though improvised  counterpoint�in which the voices probably moved mostly parallel to  each other, and thus failed to convey an impression of independence�  may date back to some centuries earlier. The desire to ensure pleasant  consonances and avoid unpleasant dissonances when improvising (see  consonance and dissonance) called for principles of simultaneous vocal  motion (voice leading). Because the relative movement of voices  approaching and leaving given intervals was thought to produce effects  that were more or less pleasing, rules were created to govern various types  of relative motion. The �vertical� aspect of counterpoint�the relation�  ship between the melodic lines�came to be studied as harmony, espe�  cially from the 18th century. Though harmony and counterpoint are  intimately intertwined, most of the multivoiced music of the Middle Ages  and the Renaissance is considered essentially polyphonic or  contrapuntal�that is, consisting of a combination of relatively indepen�  dent and integral melodic lines. In the Baroque era, with the invention of  figured bass and the continuo, the balance began to shift toward a har�  monic orientation.</p><p>countertenor Adult male alto voice, either natural or falsetto. Some  writers use the term only for the natural high tenor, preferring �male alto�  for the falsetto voice. Like the castrato tradition, the countertenor devel�  oped as a result of the prohibition on women taking part in church choirs.  Since the falsetto voice lacks power, it was little used in opera. The coun�  tertenor tradition was preserved in the English cathedral choir. Today it  is again being widely cultivated internationally, primarily for Renaissance  and Baroque music.</p><p>country dance or contredanse Vkan-tr3-,dans\ Type of social  dance for couples, popular in the 17th century. Derived from English folk  dance, the country dance is performed in one of three forms: circular or</p><p>round; �longways,� with rows of couples facing each other; and geomet�  ric, in squares or triangles. The main source of country-dance steps and  songs is John Playford�s The English Dancing Master (1650). The dance  was the basis for the 19th-century quadrille. It was taken by colonists to  North America as the Virginia reel and, in modified form, as the square  dance. There was a modest revival in the 20th century.</p><p>country music or country and western Musical style that origi�  nated among whites in rural areas of the southern and western U.S. The  term country and western music was adopted by the music industry in  1949 to replace the derogatory hillbilly music. Its roots lie in the music  of the European settlers of the Appalachians and other areas. In the early  1920s the genre began to be commercially recorded; Fiddlin� John Car-  son recorded its first hit. Radio programs such as Nashville�s Grand Ole  Opry and Chicago�s National Barn Dance fueled its growth, and grow�  ing numbers of musicians, such as the Carter Family and Jimmie Rodgers,  began performing on radio and in recording studios. With the migration  of Southern whites to industrial cities in the 1930s and �40s, country music  was exposed to new influences, such as blues and gospel music. Its nostal�  gic bias, with its lyrics about poverty, heartbreak, and homesickness, held  special appeal during a time of great population shifts. In the 1930s �sing�  ing cowboy� film stars, such as Gene Autry, altered country lyrics to pro�  duce a synthetic �western� music. Other variants include western swing  (see Bob Wills) and honky-tonk (see Ernest Tubb and Hank Williams). In the  1940s there was an effort to return to country�s root values (see bluegrass),  but commercialization proved a stronger influence, and in the 1950s and  �60s country music became a huge commercial enterprise. Popular sing�  ers often recorded songs in a Nashville style, while many country music  recordings employed lush orchestral backgrounds. Country music has  become increasingly acceptable to urban audiences, retaining its vitality  with diverse performers such as Willie Nelson, Waylon Jennings, Dolly  Parton, Randy Travis, Garth Brooks, Emmylou Harris, and Lyle Lovett.  Despite the influence of other styles, it has retained an unmistakable char�  acter as one of the few truly indigenous American musical styles.</p><p>coup d'etat \,ku-da-'ta\ or coup (French: �stroke of state�) Sudden  overthrow, often violent, of an existing government by a group of con�  spirators.

His other works include a collection of more than 40 organ compositions  {Pieces d�orgue, 1709); much sacred vocal music (including the Legons  de tenebres, c. 1715); and several sets of chamber music (including the  Concerts royaux , 1722). His Art of Playing the Harpsichord (1716) is the  most valuable instrumental treatise of its time. He was the foremost  French composer of his generation. His uncle Louis Couperin (1626-61),  also organist at St. Gervais, composed more than 200 keyboard works.</p><p>couple In physics, a pair of equal parallel forces that are opposite in  direction. Couples produce or prevent the turning of a body. The forces  used to turn the steering wheel of a car constitute a couple; each hand  exerts a force, parallel but opposite in direction, yet they work together  to achieve the same goal. A couple is also used to turn a screwdriver or  a doorknob, and the pair of forces acting on the opposite poles of a com�  pass needle as it points somewhere between north and south are a couple.</p><p>couplet Two successive lines of verse. A couplet is marked usually by  rhythmic correspondence, rhyme, or the inclusion of a self-contained  utterance. Couplets may be independent poems, but they usually function  as parts of other verse forms, such as the Shakespearean sonnet, which  concludes with a couplet. A couplet that cannot stand alone is an open  couplet; a couplet whose sense is relatively independent is a closed cou�  plet.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>courante &#x25BA; courtly love I 475</p><p>courante \ku-'rant\ (from Latin currere, �to run�) Court dance of the  16th century, fashionable in European ballrooms into the 18th century.

Dec. 31, 1877, La Tour-de-Peilz, Switz.) French painter. In 1839 he went  to Paris, where, after receiving some formal training, he learned by copy�  ing Old Masters in the Louvre. His early works were controversial but  received public and critical acclaim. In 1849 and 1850 he produced two  of his greatest paintings: respectively, The Stone-Breakers and Burial at  Ornans. Both works depart radically from the more-controlled, idealized  pictures of either the Neoclassical or the Romantic school; they portray the  life and emotions not of aristocrats but of humble peasants, and they do  so with a realistic urgency. Such images of everyday life, characterized  by a powerful naturalism and boldly portrayed, cast him as a revolution�  ary socialist. An intimate of many writers and philosophers of his day, he  became the leader of the new school of Realism, which in time prevailed  over other contemporary movements. His audacity and disrespect for  authority were notorious. In 1865 his series depicting storms at sea  astounded the art world and opened the way for Impressionism.</p><p>Detail from Pierre-Joseph Proudhon and His Children in 1853, oil on canvas by  Gustave Courbet, 1865; in the Musee du Petit Palais, Paris.</p><p>� DEA PICTURE LIBRARY</p><p>coureur de bois Vkii-'rcer-do-'bwaV French "wood runner" French  Canadian fur trader of the late 17th and early 18th centuries. Most of the  coureur de bois traded illicitly (i.e., without the license required by the  Quebec government). They sold brandy to Indians, which created diffi�  culties for the tribes with whom they traded. Though they defied the colo�  nial authorities, they ultimately benefited them by exploring the frontier,  developing the fur trade, and helping ally the Indians with the French and  against the English (see French and Indian War).</p><p>Courland Vkur-,lant,\ English Vkur-landN Latvian Kurzeme  Vkur-zo-.maV Historical region, Latvia.

Conquered in the 13th century by the Livo�  nians, in 1561 the area was incorporated into the duchy of Courland,  which became a Polish fief. The duchy flourished during the 17th century  with the development of industries and foreign trade. From 1737 its duke  was a client of the Russian throne, and it came under Russian rule in 1795.

In 1961  he opened his own house and became established as one of the most  original couturiers in Paris. His futuristic styles featured well-cut pants,  trapezoidal lines, and miniskirts with white midcalf boots; white became  his hallmark. In the 1960s his designs were widely copied. He established  control over manufacturing and distribution through licensed outlets.</p><p>court In architecture, an outdoor room surrounded by buildings or walls.  Courts have existed in all civilizations from the earliest recorded times.  The small garden court (atrium) of a Roman house was the center of  domestic activity. In medieval Europe the court was a feature of all major  residential buildings, as the cloister of a monastery, ward of a castle, or  quadrangle of a college. A courtyard is often a utilitarian court (as for  stables).</p><p>court Official assembly with judicial authority to hear and determine  disputes in particular cases. In early judicial tribunals, judges sat in enclo�  sures (courts in an architectural sense), and lawyers and the general pub�  lic remained outside a bar (hence the term bar in legal contexts). Modem  British courts are divided into those trying criminal cases and those try�  ing civil cases; a second distinction is made between inferior courts, or  courts of first instance, and superior courts, or courts of appeal. In the  U.S. each state has its own system of courts, usually consisting of a supe�  rior (appellate) court, trial courts of general jurisdiction, and specialized  courts (e.g., probate courts). The U.S. also has a system of federal courts,  established to adjudicate distinctively national questions and cases not  appropriately tried in state courts. At the apex of the national system is  the Supreme Court of the United States. The secondary level consists of the  United States Courts of Appeals. United States District Courts form the ter�  tiary level. Crimes committed by military figures may be tried in a court-  martial. In the past, ecclesiastical courts had broad jurisdiction.

Most countries today have military codes of  justice administered by military courts, often subject to civilian appellate  review. Courts-martial are generally convened as ad hoc courts to try one  or more cases referred by some high military authority. The convening  officer chooses officers, and sometimes enlisted personnel, from his or her  command to sit on the court, determine guilt or innocence, and hand down  sentences.

Courtship may simply involve a few chemical, visual, or  auditory stimuli, or it may be a highly complex series of acts by two or  more individuals using several modes of communication. Females of  some insect species use pheromones to attract males from a distance.  Painted turtles court by touch, and the courtship songs of frogs are heard  on spring nights across much of the world. Certain bird species have  complex courtship patterns. Courtship is important as an isolating mecha�  nism to prevent different species from interbreeding, and elaborate court�  ship rituals help strengthen pair bonds that may last through the raising  of the young or longer.

For decades, beginning in 1950, he traveled  the world in research vessels named Calypso. He invented a process for  using television underwater, and he hosted an internationally successful  television series (1968-76). He served as director of Monaco�s Oceano�  graphic Museum (1957-88).

In covalent bonds, two atoms share one or more pairs  of valence electrons to give each atom the stability found in a noble gas. In  single bonds (e.g., H�H in molecular hydrogen), one electron pair is  shared; in double bonds (e.g., 0=0 in molecular oxygen or H 2 C=CH 2 in  ethylene), two; in triple bonds (e.g., HC=CH in acetylene), three. In coor�  dinate covalent bonds, additional electron pairs are shared with another  atom, usually forming a functional group, such as sulfate (S0 4 ) or phos�  phate (P0 4 ). The number of bonds and the atoms participating in each  (including any additional paired electrons) give molecules their configu�  ration; the slight negative and positive charges at the opposite ends of a  covalent bond are the reason most molecules have some polarity (see elec�  trophile; nucleophile). Carbon in organic compounds can have as many as  four single bonds, each pointing to one vertex of a tetrahedron; as a result,  certain molecules exist in mirror-image forms (see optical activity). Double  bonds are rigid, leading to the possibility of geometric isomers (see isom�  erism). Some types of bonds, such as the amide linkages that join the amino  acids in peptides and proteins (peptide bonds), are apparently single but have  some double-bond characteristics because of the electronic structure of the  participating atoms. The configurations of enzymes and their substrates,  determined by their covalent bonds (particularly the peptide bonds) and  hydrogen bonds, are crucial to the reactions they participate in, which are  fundamental to all life.

God�s revelation of the law  to Moses on Mount Sinai created a pact between God and Israel known  as the Sinai covenant.

After the signing of the National Covenant of  1638, the Scottish Assembly abolished the episcopal system. In the Bish�  ops� Wars of 1639-40 the Scots fought against England to maintain their  religious liberty. In England the expenses of these wars were a factor in  the English Civil War, and in the Solemn League and Covenant of 1643  the Scots promised their aid to the parliamentarian faction provided that  the Church of England was reformed along Presbyterian lines. Crom�  well�s settlement failed to satisfy the Covenanters, but their situation  worsened considerably once Charles II came to the throne in 1660. Epis�  copacy was brought back, and the Covenanters endured severe persecu�  tions. Not until the Glorious Revolution of 1688 was Presbyterianism  reestablished in Scotland.</p><p>Covent Vk9-v3nt\ Garden Square in London. It is now the site of the  Royal Opera House, home of the British national opera and ballet com�  panies.

The original Co vent Garden playhouse, called  the Theatre Royal, was built in 1732 and served for performances of plays,  pantomimes, and opera. Twice destroyed by fire and rebuilt, the theatre  became the Royal Italian Opera House (1847) and was replaced by the  Royal Opera Co. (1888).

He lived abroad during 1528-34 to escape persecution, and  while in Antwerp he translated the entire Bible into English; his Bible was  published in 1535. He returned to England and edited the Great Bible  (1539) but was soon forced to flee by the religious policies of Henry VIII.  He returned after Henry�s death and became bishop at Exeter in 1551.

It is rooted in David Hume�s doctrine that, when two  events are said to be causally related, all that is meant is that they instan�  tiate certain regularities of succession that have been repeatedly observed  to hold between such events in the past. This doctrine was given more  rigorous expression by the logical positivist Carl Hempel (1905-1997).</p><p>coverture Vko-var-.churV In law, the inclusion of a woman in the legal  person of her husband upon marriage.

An actor from age 12, he wrote light comedies between  engagements, but it was a serious drama. The Vortex (1924), that estab�  lished his reputation. His classic comedies came later: Hay Fever (1925),  Private Lives (1930), Design for Living (1933), Present Laughter (1939),  and Blithe Spirit (1941) presented sophisticated characters in a worldly  milieu. He often wrote for and performed with his close friend Gertrude  Lawrence. His most popular musical play was Bitter Sweet (1929). He  wrote the poignant film Brief Encounter (1945), and he acted in the film  versions of many of his plays. He also wrote short stories, novels, and  numerous songs, including �Mad Dogs and Englishmen.�</p><p>cowbird Any of six passerine species related to New World blackbirds  (family Icteridae) that exhibit brood parasitism. Cowbirds lay their eggs  in the nests of other birds, usually one to each host nest. Young cowbirds,  which displace nestlings or outcompete them for food, may grow larger  than the foster parents. In parts of North America, the brown-headed  cowbird ( Molothrus ater) parasitizes the nests of more than 200 other bird  species; others use the nests of only one or two kinds of oriole. Cowbirds  forage on the ground, often associating with cattle in order to catch insects  stirred up by the cows� hooves. The male of most species is a uniform  glossy black, the female grayish brown.</p><p>cowboy Horseman skilled at handling cattle in the U.S. West. From c.  1820, cowboys were employed in small numbers on Texas ranches, where  they had learned the skills of the vaquero (Spanish: �cowboy�). After the  Civil War, their numbers rapidly multiplied as cattle raising evolved into  a lucrative industry throughout the western territories. Cowboys rounded  up and branded the cattle, kept watch over the herd, and drove those ready  for market to railroad towns. As the agricultural frontier moved west, the  open range was transformed into farms, and by 1890 cowboys had been  forced to settle on ranches. The romance of their image lived on in U.S.  folklore and through movies and television.</p><p>Cowell, Henry (Dixon) (b. March 11, 1897, Menlo Park, Calif.,  U.S.�d. Dec. 10, 1965, Shady, N.Y.) U.S. avant-garde composer. He  began early to experiment with techniques such as tone clusters and direct  manipulation of piano strings. Five tours of Europe as composer-pianist  (1923-33) expanded his reputation. He coinvented the Rhythmicon, an  instrument for producing several conflicting rhythms simultaneously.  Immensely prolific, he wrote nearly 1,000 pieces, including 19 completed  symphonies, hundreds of piano works, and many ballets. In 1927 he  founded the journal New Music. His book New Musical Resources (1930)  presented his compositional ideas. He was one of the most important  innovators in the history of American music.</p><p>Cowley, Abraham (b. 1618, London�d.

He was known for his por�  trait busts, which show a naturalism and animation of expression that  anticipates the Rococo style. He also executed decorative sculpture for the  royal gardens and did much interior decoration. Coysevox exerted con�  siderable influence on the development of French portrait sculpture in the  18th century.</p><p>CP violation In particle physics, the violation of the combined conser�  vation laws associated with charge conjugation, C (the operation of turn�  ing a particle into its antiparticle), and parity, P, by the weak force. In 1957  it was discovered that parity is violated in beta decay. No fully satisfac�  tory explanation has been devised, but CP violation does enable physi�  cists to make an absolute distinction between matter and antimatter.</p><p>CPR See cardiopulmonary resuscitation</p><p>CPU in full central processing unit Principal component of a digi�  tal computer, composed of a control unit, an instruction-decoding unit, and  an arithmetic-logic unit. The CPU is linked to main memory, peripheral  equipment (including input/output devices), and storage units. The con�  trol unit integrates computer operations. It selects instructions from the  main memory in proper sequence and sends them to the instruction�  decoding unit, which interprets them so as to activate functions of the  system at appropriate moments. Input data are transferred via the main  memory to the arithmetic-logic unit for processing (i.e., addition, subtrac�  tion, multiplication, division, and certain logic operations). Larger com�  puters may have two or more CPUs, in which case they are simply called  �processors� because each is no longer a �central� unit.

Its cara�  pace (upper body shield) is usually  broad, and its first pair of legs is  modified into pincers. Most crabs  live in the sea and breathe through  gills, which in land crabs are modi�  fied to serve as lungs. They walk or  crawl, generally with a sideways  gait; some are good swimmers.</p><p>Crabs are omnivorous scavengers,  but many are predatory and some are  herbivorous. Two of the largest  known crustaceans are the giant crab  of Japan (13 ft, or 4 m, from claw tip  to claw tip), a spider crab; and the Tas�  manian crab (up to 18 in., or 46 cm,  long, and weighing more than 20 lbs,  or 9 kg). Other species are less than  an inch long. Well-known crabs  include the hermit crab, edible crab (Britain and Europe), blue crab, Dunge-  NESS CRAB, FIDDLER CRAB, and KING CRAB.</p><p>crab louse See human louse</p><p>Crab Nebula Bright nebula in the constellation Taurus, about 5,000  light-years from Earth. Roughly 12 light-years in diameter, it is the rem�  nant of a supernova, first observed by Chinese and other astronomers in  1054, that was visible in daylight for 23 days and at night for almost two  years. Identified as a nebula c. 1731, it was named (for its form) in the  mid-19th century. In 1921 it was discovered to be still expanding; the  present rate is about 700 mi/second (1,100 km/second). The Crab is one  of the few astronomical objects from which electromagnetic radiation has</p><p>been detected over the entire measurable spectrum. In the late 1960s a pul�  sar, thought to be the collapsed remnant star of the supernova, was found  near its centre.</p><p>Crabbe VkrabV George (b. Dec. 24, 1754, Aldeburgh, Suffolk,  Eng.�d. Feb. 3, 1832, Trowbridge, Wiltshire) English poet. Reared in an  impoverished seacoast village, Crabbe initially became a surgeon. In 1780  he left for London, where his poem The Village (1783) brought him fame;  written partly as a protest against Oliver Goldsmith�s Deserted Village  (1770), it was Crabbe�s attempt to show the misery of rural poverty. The  Newspaper followed in 1785, but he did not publish again until 1807. In  �The Parish Register,� he used the register of births, deaths, and marriages  to depict the life of a rural community. Considered the last of the Augustan  poets, he wrote in heroic couplets. His story of the isolated and violent  Peter Grimes in The Borough became the basis of a famous opera by Ben�  jamin Britten.</p><p>crabgrass Any of about 300 species of grasses in the genus Digitaria,  especially D. sanguinalis or the  slightly shorter D. ischaemum  (smooth crabgrass). D. sanguinalis  has long hairs covering its leaves and  five or six spikelets; D. ischaemum  has no hair and only two or three  spikelets. Both are natives of Europe  that became widely naturalized as  weeds in North America. They and a  few closely related species are very  troublesome in lawns and fields. One  species, Arizona cottontop ( D . cali-  fornica ), is a useful forage grass in  the American Southwest.</p><p>Cracow See Krakow</p><p>Craig, (Edward Henry) Gor�  don (b.

The  son of Ellen Terry, he acted with Henry Irving�s company (1889-97), then  turned to designing stage sets, decor, and costumes. He moved to Flo�  rence (1906), where he opened the School for the Art of the Theatre  (1913). His international journal The Mask (1908-29) made his theatri�  cal ideas widely known. His books On the Art of the Theatre (1911),  Towards a New Theatre (1913), and Scene (1923) outlined innovations in  stage design based on the use of portable screens and changing patterns  of light; his theories influenced the antinaturalist trends of the modern  theatre.</p><p>Craig, Sir James (Henry) (b. 1748, Gibraltar�d. Jan. 12, 1812,  London, Eng.) British army officer and governor-general of Canada  (1807-11). In the American Revolution, he was wounded at the Battle of  Bunker Hill in 1775 and helped repel the American army�s invasion of  Canada in 1776. He later served in India. As governor-general in Canada,  he cooperated with the governing clique in Quebec but conducted an  unpopular repressive policy toward French Canadians. He resigned in  1811 and returned to England.</p><p>Craigavon \kra-'ga-v9n\ District (pop., 2001: 80,671), Northern Ire�  land. Established in 1973, it lies south of Lough Neagh.

From the  late 15th to the 18th century it was the residence of the region�s military  governors. It prospered as a regional trading centre despite an earthquake  in 1790 and a Turkish assault in 1802 during which it was burned. It has  a university (1966) and other cultural amenities.</p><p>cramp Painful, involuntary, sustained contraction of muscle in limbs or  some internal organs.

Lucas Muller (b. 1472,  Cranach, bishopric of Bamberg�d. Oct. 16,1553, Weimar, Saxe-Weimar)  German painter and printmaker. He took his name from the town of his  birth. Little is known about his early life or training. In Vienna (c. 1501�  04) he painted some notable portraits and landscapes characteristic of the  Danube school. From 1505 to 1550 he was court painter in Wittenberg,  where he achieved great success and wealth painting portraits, mytho�  logical subjects, and altarpieces for Protestant and Catholic churches. He  attracted so many young artists to Wittenberg that the town became an art  centre. A friend of Martin Luther, Cranach became known as the chief pic�  torial propagandist of the Protestant cause in Germany. He produced  numerous engravings and more than 100 woodcuts, notably for the first  German edition of the New Testament (1522). After his death, his style  was perpetuated by his son, Lucas the Younger (1515-86).</p><p>cranberry Fruit of any of several small creeping or trailing plants of  the genus Vaccinium (heath family),  related to the blueberry. The small-  fruited, or northern, cranberry (V  oxycoccus) is found in marshy land  in northern North America and Asia  and in northern and central Europe.</p><p>Its crimson berries, about the size of  currants and often spotted, have an  acid taste. The American cranberry  (V macrocarpon), found wild in  most of the northeastern U.S. and  grown extensively in Massachusetts,</p><p>New Jersey, and Wisconsin and near  the Pacific coast in Washington and  Oregon, is more robust than V. oxy�  coccus, with larger, pink to very dark  red or mottled red-and-white berries.</p><p>Cranberries are used in drinks,  sauces, jellies, and baked goods.</p><p>crane Any of a diverse group of  machines that lift and move heavy objects. Cranes differ from hoists, eleva�  tors, and other devices intended for vertical lifting, and from conveyors,  which continuously lift or carry bulk materials such as grain or coal. Cranes  have been widely used only since the introduction of steam engines,  internal-combustion engines, and electric motors in the 19th century. They  range in type and function from the largest derrick cranes to small, mobile  truck cranes. Most derrick cranes can lift 5-250 tons (4.5-230 metric tons).  Floating cranes, built on barges for constructing bridges or salvaging  sunken objects, may be able to lift 3,000 tons (2,700 metric-tons). Small  truck cranes are mounted on heavy, modified trucks; they make up in  mobility and ease of transport what they lack in hoisting capacity.</p><p>crane Any of 15 species (family Gruidae) of tall wading birds that  resemble herons but are usually larger and have a partly naked head, a  heavier bill, more-compact plumage, and an elevated hind toe. In flight,  the long neck stretches out in front and the stiltlike legs trail behind.  Cranes are found worldwide, living in marshes and on plains, except in  South America. Many populations are endangered by hunting and habitat  destruction. Cranes eat small animals, grain, and grass shoots. Two well-  known species are the whooping crane and the sandhill crane.</p><p>crane flower See bird-of-paradise</p><p>crane fly Harmless, slow-flying dipteran (family Tipulidae) usually  found around water or abundant vegetation. It ranges in size from tiny to  slightly over 1 in. (2.5 cm) long. Larvae of the range crane fly ( Tipula  simplex) are called leatherjackets because of their tough brown skin. In  northern latitudes a wingless crane-fly species is found on snow. The crane  fly is also called daddy longlegs in English-speaking countries other than  the U.S. (in the U.S., daddy longlegs refers to an arachnid).</p><p>Crane, (Harold) Hart (b. July 21, 1899, Garrettsville, Ohio, U.S.�d.  April 27, 1932, at sea, Caribbean Sea) U.S. poet. Crane worked at a vari�  ety of jobs before settling in New York City. White Buildings (1926), his  first book, includes �For the Marriage of Faustus and Helen.� His desire  to respond to the cultural pessimism of T.S. Eliot�s The Waste Land</p><p>Cranberry (Vaccinium macrocarpon)</p><p>WALTER CHANDOHA</p><p>resulted in the long and difficult poem The Bridge (1930), which attempts  to create an epic myth of the American experience, celebrating the rich�  ness of modern life with visionary intensity.

June 5,</p><p>1900, Badenweiler, Baden, Ger.)  U.S. novelist and short-story writer.  Crane briefly attended college before  moving to New York City. His Mag�  gie: A Girl of the Streets (1893), a  sympathetic study of a slum girl�s  descent into prostitution, was a mile�  stone of literary naturalism. He  achieved international fame with his  masterwork, The Red Badge of  Courage (1895), depicting the psy�  chological turmoil of a young Civil  War soldier, and with his first book  of poems, The Black Riders (1895).  While traveling as a war correspon�  dent, his ship sank and he almost  drowned, resulting in his great story  �The Open Boat� (1898). His story  collections include The Little Regi�  ment (1896), The Monster (1899),  and Whilomville Stories (1900). He  died at 28 of tuberculosis.</p><p>Stephen Crane, detail of a painting by  C.K.

March 14, 1915,  Horsham) English illustrator, painter, and designer. The son of a portrait  painter, he studied Italian Old Masters and Japanese prints. The ideas of  the Pre-Raphaelites and John Ruskin inspired his early paintings. He  achieved international popularity designing Art Nouveau textiles and  wallpapers but is chiefly known for his illustrations of children�s books. In  1894 he worked with William Morris on The Story of the Glittering Plain,  a book printed in the style of 16th-century German and Italian woodcuts.  He belonged to the Art Workers� Guild, and in 1888 he founded the Arts  and Crafts Exhibition Society.

Pressure from the growing brain normally causes the  skull bones to grow along the seams (cranial sutures) between them. If  all the sutures fuse early, the head remains abnormally small, which can  cause mental retardation or blindness. If only one or some fuse early, the  skull grows in other directions and becomes deformed. Surgery in the first  two years to keep the sutures open longer minimizes these complications.</p><p>crank In mechanics, an arm secured at right angles to a shaft with which  it can rotate or oscillate. Next to the wheel, the crank is the most impor�  tant motion-transmitting device, because, with the connecting rod, it pro�  vides means for converting linear to rotary motion, and vice versa. The  first recognizable crank is said to have appeared in China in the 1 st cen�</p><p>tury ad. The carpenter�s brace was  invented c. 1400 by a Flemish car�  penter. The first mechanical connect�  ing rods were reportedly used on a  treadle-operated machine in 1430.

After  Henry�s death in 1547, Cranmer became an influential adviser to the young  Edward VI, moving England firmly in a Protestant direction. He wrote the  Forty-two Articles, from which the Thirty-nine Articles of Anglican belief  were derived. When the strongly anti-Protestant Mary I became queen,  Cranmer was tried, convicted of heresy, and burned at the stake.</p><p>crannog Vkra-.nog, kra-'nog\ In Scotland and Ireland, an artificially  constructed site for a house or settlement, usually on an islet or in the  shallows of a lake.

Native to the eastern U.S. but introduced elsewhere, crappies  may reach a length of about 12 in. (30 cm) and a weight of about 4 lb (2  kg). The white crappie (Pomoxis annularis ) generally inhabits warm, silty  lakes and rivers. Silvery with irregular dark markings, it is usually lighter  in colour than the similar black crappie, or calico bass ( P. nigromacula-  tus), which typically lives in clear lakes and streams.</p><p>craps Gambling game in which each player in turn throws two dice,  attempting to roll a winning combination. The term derives from a Loui�  siana French word, crabs , which means �losing throw.� The player with  the dice (the shooter) must first put up a stake; the other players bet against  the shooter up to the amount of the stake. In some games, bettors may  also bet against each other or against the house. A shooter who wins may  continue to roll. A 7 or 11 on the first roll wins; a 2, 3, or 12 (craps) loses.

Most cra�  ters are the result of impacts of meteorites or of volcanic explosions. Mete�  orite craters are more common on the Moon and Mars and on other planets  and natural satellites than on Earth, because most meteorites either burn  up in the Earth�s atmosphere before reaching its surface or erosion soon  obscures the impact site.

In 1762  Josiah Wedgwood achieved commer�  cial success with this modestly  priced utilitarian ware; restrained  designs and elegant transfer printing  (see Battersea enamelware) were com�  patible with his cream-glazed prod�  ucts. By 1790 many other factories  (e.g., Liverpool, Bristol, Stafford�  shire) were producing creamware  with success; continental imitations  were generally inferior. Creamware  was continually made throughout the  19th century and later.</p><p>creation myth or cosmogony</p><p>\kaz-'ma-g9-ne\ Symbolic narrative  of the creation and organization of  the world as understood in a particular tradition. Not all creation myths  include a creator, though a supreme creator deity, existing from before  creation, is very common. Myths in which the world emerges gradually  emphasize the latent power of the earth. In other creation myths, the world  is the offspring of primordial parents, derives from a cosmic egg, or is  brought up from primordial waters by an animal or devil. Humans may  be placed on earth by a god or rise from its depths or from a cultic rock  or tree. There are often three stages of creation: that of primordial beings  or gods, that of human ancestors who are often semidivine, and that of  humans. Creation myths explain or validate basic beliefs, patterns of life,  and culture. Rituals dramatize the myth and, particularly in initiations,  validate the community�s organization and rankings.</p><p>creationism The belief that matter, the various forms of life, and the  world were created by God out of nothing. Biblical creationists believe  that the story told in Genesis of God�s six-day creation of the universe  and all living things is literally correct. Scientific creationists believe that  a creator made all that exists, though they may not hold that the Genesis  story is a literal history of that creation. Creationism became the object  of renewed interest among conservative religious groups following the  wide dissemination of the theory of biological evolution, first systemati�  cally propounded by Charles Darwin in On the Origin of Species (1859).  In the early 20th century some U.S. states banned the teaching of evo�  lution, leading to the Scopes Trial. In the late 20th century many creation�  ists advocated a view known as intelligent design, which was essentially a  scientifically modern version of the argument from design for the existence  of God as set forth in the late 18th century by the Anglican clergyman  William Paley.</p><p>creativity Ability to produce something new through imaginative skill,  whether a new solution to a problem, a new method or device, or a new  artistic object or form. The term generally refers to a richness of ideas and  originality of thinking. Psychological studies of highly creative people  have shown that many have a strong interest in apparent disorder, con�  tradiction, and imbalance, which seem to be perceived as challenges. Such  individuals may possess an exceptionally deep, broad, and flexible aware�  ness of themselves. Studies also show that intelligence has little correla�  tion with creativity; thus, a highly intelligent person may not be very  creative. See also genius; gifted child.</p><p>Crecy \kra-'se. Battle of (August 26, 1346) English victory in the first  phase of the Hundred Years' War against the French. At Crecy-en-  Ponthieu, Edward III of England defeated Philip VI of France, even though  the English forces were greatly outnumbered. The English gained the  advantage because their archers were armed with longbows and because  of their strong defensive position.</p><p>credit Transaction between two parties in which one (the creditor or  lender) supplies money, goods, services, or securities in return for a prom�  ised future payment by the other (the debtor or borrower). Such transac�  tions normally include the payment of interest to the lender. Credit may  be extended by public or private institutions to finance business activities,  agricultural operations, consumer expenditures, or government projects.  Large sums of credit are usually extended through specialized financial  institutions such as commercial banks or through government lending pro�  grams.</p><p>credit bureau Organization that provides information to merchants or  other businesses concerning the creditworthiness of their customers.  Credit bureaus may be private enterprises or may be operated on a coop�  erative basis by the merchants in one locality. Users of the service pay a  fee and receive information from various sources, including businesses  that have granted the customer credit in the past, public records, news�  papers, the customer�s employment record, and direct investigation.</p><p>credit card Small card that authorizes the person named on it to charge  goods or services to his or her account. It differs from a debit card, with  which money is automatically deducted from the bank account of the  cardholder to pay for the goods or services. Credit-card use originated in  the U.S. in the 1920s; early credit cards were issued by various firms (e.g.,  oil companies and hotel chains) for use at their outlets only. The first uni�  versal credit card, accepted by a variety of establishments, was issued by  Diners� Club in 1950. Charge cards such as American Express require card�  holders to pay for all purchases at the end of the billing period (usually  monthly). Bank cards such as MasterCard and Visa allow customers to  pay only a portion of their bill; interest accrues on the unpaid balance.  Credit-card companies get revenue from annual fees and interest paid by  cardholders and from fees paid by participating merchants.</p><p>Credit Mobilier Vkred-it-mo-'bel-yorA French \kra-'de- l m6-bel- , ya\  scandal (1872 -73) Illegal manipulation of construction contracts for the  Union Pacific Railroad that became a symbol of corruption after the Ameri�  can Civil War. The railroad�s major stockholders created Credit Mobilier  of America to divert its construction profits and gave or sold stock to  influential politicians in return for favours. A newspaper exposed the  scheme in 1872, and after a Congressional investigation two members of  the House of Representatives were censured.</p><p>credit union Credit cooperative formed by a group of people with some  common bond who, in effect, save their money together and make low-</p><p>Leeds creamware teapot decorated  with green enameling and pierced  work, Yorkshire, England, late 18th  century; in the Victoria and Albert  Museum, London</p><p>COURTESY OF THE VICTORIA AND ALBERT MUSEUM,  LONDON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>482 I creditor &#x25BA; Cressent</p><p>cost loans to each other. The loans are usually short-term consumer loans,  mainly for automobiles, household needs, medical debts, and emergen�  cies. Credit unions generally operate under government charter and super�  vision. They are particularly important in less developed countries, where  they may be the only source of credit for their members. The first coop�  erative societies providing credit were founded in Germany and Italy in  the mid-19th century; the first North American credit unions were founded  by Alphonse Desjardins in Levis, Quebec (1900), and Manchester, N.H.  (1909). The Credit Union National Association (CUNA), a federation of  U.S. credit unions, was established in 1934 and became a worldwide  association in 1958.</p><p>creditor See debtor and creditor</p><p>Cree One of the major ALGONQUiAN-speaking Indian peoples of Canada  living mainly in Saskatchewan and Alberta. The name is a truncated form  of the name �Kristineaux,� the French traders� version of the self-name  of the James Bay band. The Cree formerly occupied an immense area  from western Quebec to eastern Alberta. They acquired firearms and  engaged in the fur trade with Europeans beginning in the 17th century.  There were two major divisions: the Woodland Cree, whose culture was  essentially an Eastern Woodlands type, and the Plains Cree, bison hunt�  ers of the northern Great Plains (see Plains Indian). Social organization in  both groups was based on local bands. Among the Woodland Cree, ritu�  als and taboos relating to the spirits of game animals were pervasive, as  was fear of witchcraft. Among the more militant Plains Cree, rites  intended to foster success in warfare and the bison hunt were common.  Some 600,000 Canadians claim some portion of Cree ancestry, and about  2,500 individuals claimed sole Cree descent in the 2000 U.S. census.</p><p>creed Officially authorized, usually brief statement of the essential  articles of faith of a religious community, often used in public worship  or initiation rites. Creeds are most numerous in Western traditions. In Islam  the shahada declares that only God is God and Muhammad is his prophet.  In Judaism early creeds are preserved in Hebrew scripture, and later creeds  include the Thirteen Principles of Faith. In Christianity the Nicene Creed was  formulated in ad 381 to exclude Arianism, and the Apostles� Creed was  drafted in the 8th century from earlier baptismal creeds. Buddhism, Zoro�  astrianism, and modern movements of Hinduism also possess creeds; in  other religions faith is confessed chiefly through liturgical expressions.</p><p>Creek or Muscogee MusKOGEAN-speaking North American Indian  people living mainly in Oklahoma,</p><p>U.S., but also in Georgia and Ala�  bama. A loose and shifting confed�  eration of groups that once occupied  much of the Georgia and Alabama  flatlands, the Creek comprised two  major divisions: the Upper Creeks  (living on the Coosa and Tallapoosa  rivers) and the Lower Creeks (living  on the Chatahootchee and Flint riv�  ers). They cultivated corn, beans,  and squash. Each Creek town had a  plaza or community square, often  with a temple, around which were  built the rectangular houses. Reli�  gious observances included the Busk  (Green Corn) ceremony, an annual  first-fruits and new-fire rite. In the  18th century a Creek Confederacy�  including the Natchez, Yuchi, Shaw�  nee, and others�was organized to  present a united front against both  European and Indian enemies. It  proved a failure, however, since at no  time did all groups contribute war�  riors to a common battle. The Creek  War against the U.S. (1813-14) ended with the defeated Creeks ceding  23 million acres. Most were forcibly removed to Indian Territory (Okla�  homa). Some 40,200 individuals claimed sole Creek ancestry in the 2000  U.S. census.</p><p>creep Slow change in the dimensions of a material from prolonged stress.  Most common metals exhibit creep behaviour. In the creep test, loads  below those that ordinarily cause plastic flow or fracture are applied to</p><p>the material, and the deformation over a period of time (creep strain) under  constant load is measured, usually with an extensometer or strain gauge.  Time to failure is also measured against stress. Once creep strain versus  time is plotted, various mathematical techniques are available for extrapo�  lating creep behaviour beyond the test times; thus, designers can use  thousand-hour test data, for example, to predict ten-thousand-hour behav�  iour. See also testing machine.</p><p>cremation Disposing of a corpse by burning. In the ancient world cre�  mation took place on an open pyre. It was practiced by the Greeks (who  considered it suitable for heroes and war dead) and the Romans (among  whom it became a status symbol). The pagan Scandinavians also cremated  their dead. In India the custom is very ancient. In some Asian countries  only certain people may be cremated (e.g., high lamas in Tibet). Chris�  tianity opposed cremation, and it became rare in Europe after ad 1000  except under extreme circumstances, such as that brought on by the Black  Death. The practice reemerged in the late 19th century and was eventu�  ally accepted by both Protestants and Roman Catholics.</p><p>Creole In the 16th-18th centuries, a person born in Spanish America of  Spanish parents, as distinguished from one born in Spain but residing in  America. Under Spanish colonial rule, Creoles suffered from discrimina�  tion; it was consequently Creoles who led the 19th-century revolutions  against Spain and became the new ruling class. Today Creole has widely  varying meanings. In Louisiana it can mean either French-speaking white  descendants of early French and Spanish settlers, or people of mixed  descent who speak a form of French and Spanish. In Latin America the  term may denote a local-born person of pure Spanish extraction or a  member of the urban Europeanized classes as opposed to rural Indians.  In the West Indies it refers to all people, regardless of ancestry, who are  part of the Caribbean culture. See also Creole language.</p><p>creole Any pidgin language that has become established as the native  language of a speech community. A creole usually arises when speakers  of one language become economically or politically dominant over speak�  ers of another. A simplified or modified form of the dominant group�s lan�  guage (pidgin), used for communication between the two groups, may  eventually become the native language of the less powerful community.  Examples include Sea Island Creole (formerly Gullah, derived from  English), spoken in South Carolina�s Sea Islands; Haitian Creole (derived  from French); and Papiamento (derived from Spanish and Portuguese),  spoken in Curasao, Aruba, and Bonaire.</p><p>creosote Vkre-9-,sot\ Either of two entirely different substances, dis�  tilled from coal tar or wood tar. Coal-tar creosote is a complex mixture  of organic compounds, largely hydrocarbons. It is a cheap water-insoluble  wood preservative used for railroad ties, telephone poles, and marine pier  pilings and as a disinfectant, fungicide, and biocide. Wood-tar creosote  consists mainly of phenols and related compounds and was once widely  used for pharmaceutical purposes.</p><p>Cresilas Vkre-si-bs\ or Kresilas (fl. 5th century bc, Athens, Greece)  Greek sculptor. He was a contemporary of Phidias. His portrait of Pericles  (c. 445 bc) generated a type of noble, idealized portraiture. A figure of a  wounded Amazon (c. 440 bc) is ascribed to him because of its resem�  blance to this head. Works attributed to Cresilas are known only in cop�  ies of lost bronze originals.</p><p>cress Any of several plants of the mustard family, of interest for their spicy  young basal leaves, which are used in salads and as seasonings and gar�  nishes. Watercress is perhaps the most popular of the edible cresses. Com�  mon garden cress, or peppergrass (. Lepidium sativum ) is widely grown,  especially in its curl-leaved form, and used as a garnish. Others include  weeds (e.g., Barbarea vulgaris), wild varieties (e.g., Cardamine praten-  sis ), and ornamentals (e.g., Arabis species).</p><p>Cressent \kres-'a n \, Charles (b. Dec. 16, 1685, Amiens, Fr.�d. Jan.  10, 1768, Paris) French cabinetmaker. He also studied sculpture and  became an accomplished metalworker. In 1710 he went to Paris, where  he worked in the studio of the cabinetmaker Andre-Charles Boulle. In 1715  Cressent was appointed official cabinetmaker to Philippe II, duke  d�Orleans. He was elected to the Academy of St.-Luc in 1719, and he  consequently received important commissions from French aristocrats,  including Madame de Pompadour. His early works were in the Louis XIV  style, but later pieces (c. 1730-50) were lighter and more curvilinear.  Cressent was the leading proponent of the Regence style and introduced  marquetries of coloured wood and ormolu to case decoration.</p><p>4</p><p>Ben Perryman, a Creek Indian, paint�  ing by George Catlin, 1836; in the  National Museum of American Art,  Smithsonian Institution, Washington,  D.C.</p><p>NATIONAL MUSEUM OF AMERICAN ART (FORMERLY  NATIONAL COLLECTION OF FINE ARTS), SMITHSONIAN  INSTITUTION, WASHINGTON, D.C., GIF OF MRS.

His numerous works, many of which achieved wide performance,  are highly rhythmical and tonally accessible. They include six sympho�  nies, a Requiem and three masses, and several concertos. He is noted for  the rhythmic vitality and full harmonies of his music, which is marked  by modem dissonances and polyrhythms.</p><p>Cretaceous \kri-'ta-shos\ Period Interval of geologic time from c. 144  to 65 million years ago. During the Cretaceous the climate was warmer  than today. In the seas, marine invertebrates flourished, and bony fishes  evolved. On land, flowering plants arose, and insects, bees in particular,  began their thriving partnership with them. Mammals and birds remained  inconspicuous throughout the Cretaceous, while the reptiles continued  their dominance. The dinosaurs reached the peak of their evolution dur�  ing this period but rather suddenly became extinct at its end.</p><p>Crete Greek Kriti \'kre-te\ ancient Creta Island (pop., 2001: 601,159)  in the eastern Mediterranean Sea and an administrative region of Greece.  It stretches for 152 mi (245 km) and varies in width from 7.5 to 35 mi  (12 to 56 km), with a total area of 3,218 sq mi (8,336 sq km). Dominated  by mountains, it was home to the Minoan civilization from c. 3000 bc and  was known for its palaces at Knossos, Phaestus, and Mallia; it reached its  peak in the 16th century bc. A major earthquake c. 1450 bc marked the  end of the Minoan era. In 67 bc Rome annexed Crete; in ad 395 it passed  to Byzantium. In 1204 Crusaders sold the island to Venice, from which it  was wrested by the Ottoman Turks in 1669 after one of history�s longest  sieges. Taken by Greece in 1898, it was autonomous until its union with  Greece in 1913. Agriculture is the economic mainstay, and the island is  one of Greece�s leading producers of olives, olive oil, and grapes; tour�  ism is also important. The museum at Iraklion houses a fine collection of  Minoan art.</p><p>Creutzfeldt-Jakob \ , kroits- l felt- , ya- l kob\ disease or CJD Rare fatal  disease of the central nervous system. It destroys brain tissue, making it  spongy and causing progressive loss of mental functioning and motor  control. The disease commonly arises in adults between the ages of 40  and 70. Patients usually die within a year. There is no known cure. The  disease is caused by a prion that builds up in neurons. Inherited or ran�  dom mutation accounts for 99% of cases; the rest come from prion expo�  sure during medical procedures and possibly from eating the meat of cattle  with MAD COW DISEASE.</p><p>crevasse \kri-'vas\ Fissure or crack in a glacier resulting from stress  produced by movement. Crevasses  range up to 65 ft (20 m) wide, 150 ft  (45 m) deep, and several hundred  yards long. Crevasses may be  bridged by snow and become hidden,  and they may close up as the glacier  moves.</p><p>CrevecoeurVkrev-'koerVMichel-  Guillaume-Saint-Jean de or  J. Hector St. John or Hector  St. John de Crevecoeur (b. Jan.</p><p>31, 1735, Caen, France�d. Nov. 12,</p><p>1813, Sarcelles) French-U.S. writer  and naturalist. He traveled to the  New World in 1755 as an officer and  mapmaker and became a farmer,  then served as French consul for  many years. He returned to Europe  in 1790. His fame rests on Letters  from an American Farmer (1782,</p><p>1784, 1790), essays that paint a  broad picture of American life. His Travels in Upper Pennsylvania and  New York appeared in 1801. Newly discovered essays were published as  Sketches of Eighteenth Century America in 1925. In his time he was the  most widely read commentator on America.</p><p>crib death See sudden infant death syndrome</p><p>cribbage Card game, usually for two players, in which each tries to  form various counting combinations of cards, the score being kept by  moving pegs on a narrow rectangular board.

After graduating from the University of St. Andrews, he publicly distin�  guished himself in Europe in learned activities. He entered the service of  the duke of Mantua but was slain in a street fight at age 21. Reputedly a  fine orator, linguist, debater, and man of letters, he was considered the  model of the cultured gentleman, though admirers probably exaggerated  his accomplishments. Years later he became known as �the Admirable  Crichton.�</p><p>Crick, Francis (Harry Compton) (b. June 8, 1916, Northampton,  Northamptonshire, Eng.�d. July 28, 2004, San Diego, Calif., U.S.) Brit�  ish biophysicist. Educated at University College, London, he helped  develop magnetic mines for naval use during World War II but returned  to biology after the war. He worked at the University of Cambridge with  James D. Watson and Maurice Wilkins to construct a molecular model of  DNA consistent with its physical and chemical properties, work for which  the three shared a 1962 Nobel Prize. Crick also discovered that each group  of three bases (a codon) on a single DNA strand designates the position  of a specific amino acid on the backbone of a protein molecule, and he  helped determine which codons code for each amino acid normally found  in protein, thus clarifying the way the cell uses DNA to build proteins.

Each  wicket is two sets of three sticks. The teams have 11 players each. A  bowler from the defending team throws the ball (with a straight-arm over�  hand delivery), attempting to hit the wicket, which is one of several ways  the batsman may be put out. The team batting fields two batsman at a  time, and the batsman being bowled to (the striker) tries to hit the ball  away from the wicket. If the batsman hits the ball away from the wicket  but has no time to run to the opposite wicket, he need not run; play will  resume with another bowl. After a hit, when possible, the striker and the  second batsman (the nonstriker) at the other wicket change places. Each  time both batsmen can reach the opposite wicket, one run is scored. The  batsmen may continue to cross back and forth between the wickets, earn�  ing an additional run for each time both reach the opposite side. Matches  are divided into innings consisting of one turn at bat for each team;  depending on pregame agreement, a match may consist of either one or  two innings. Cricket�s origins are uncertain, but the first set of rules was  written in 1744. During England�s colonial era, cricket was exported to  countries around the world.</p><p>cricket Any of the approximately 2,400 species of leaping insects (fam�  ily Gryllidae) known for the musical chirping of the male. Crickets vary in  length from around 0.1 to 2 in. (3-50 mm) and have thin antennae, hind  legs modified for jumping, and two abdominal sensory appendages  (cerci). Their two forewings are stiff and leathery, and the two long, mem�  branous hind wings are used in flying. Male crickets chirp by rubbing a  scraper located on one forewing along a row of 50-250 teeth on the oppo�  site forewing. The most common cricket songs are the calling song, which  attracts the female; the courtship, or mating, song, which induces the  female to copulate; and the fighting chirp, which repels other males.</p><p>crime the intentional commission of an act usually deemed socially harm�  ful or dangerous and specifically defined, prohibited, and punishable under  criminal law. Crimes in the common-law tradition were originally defined  primarily by judicial decision. Most common-law crimes are now codified.  According to a generally accepted principle, nullum crimen sine lege, there  can be no crime without a law. A crime generally consists of both conduct  (the actus reus) and a concurrent state of mind (the mens rea). Criminal acts  include arson, assault and battery, bribery, burglary, child abuse, counterfeit�  ing, EMBEZZLEMENT, EXTORTION, FORGERY, FRAUD, HIJACKING, HOMICIDE, KIDNAPPING,  PERJURY, PIRACY, RAPE, SEDITION, SMUGGLING, TREASON, THEFT, and USURY.

It covers 10,077 sq mi (26,100 sq km); its  capital is Simferopol. Early inhabitants were Cimmerians, though the area  later was settled by Greeks in the 6th century bc and was ruled by the  kingdom of the Cimmerian Bosporus from the 5th century bc. It became  subject to Rome, and part of it later belonged to the Byzantine Empire.  Russia annexed Crimea in 1783. It was the scene of the Crimean War  (1853-56). In 1921 it became an autonomous republic of the U.S.S.R.  During World War II, Nazi armies overran it in 1941; it was retaken by  the Soviets in 1944. The area became an oblast of the Ukrainian S.S.R.  in 1954. After the dissolution of the Soviet Union in 1991, Crimea  obtained partial autonomy from Ukraine.</p><p>Crimean War (October 1853-February 1856) War fought mainly in  the Crimea between the Russians and an alliance consisting of the Otto�  man empire, Britain, France, and Sardinia-Piedmont. It arose from the  conflict of great powers in the Middle East and was more directly caused  by Russian demands to exercise protection over the Orthodox subjects of  the Ottoman sultan. The war was managed and commanded poorly by  both sides. Battles were fought at the Alma River, Balaklava, and Inker-  man, before the besieged Sevastopol was taken by the allies. Disease  accounted for many of the approximately 250,000 men lost by each side.  After Austria threatened to join the allies, Russia accepted preliminary  peace terms, which were formalized at the Congress of Paris. The war did  not settle the relations of the powers in Eastern Europe, but it did alert  Alexander II to the need to modernize Russia.</p><p>criminal law Body of law that defines criminal offenses, regulates the  apprehension, charging, and trial of suspected offenders, and fixes pun�  ishment for convicted persons. Substantive criminal law defines particu�  lar crimes, and procedural law establishes rules for the prosecution of crime.  In the U.S., substantive criminal law originated for the most part in com�  mon law, which was later codified in federal and state statutes. Modern  criminal law has been affected considerably by the social sciences, espe�  cially in the areas of sentencing, legal research, legislation, and rehabili�  tation. See also criminology.</p><p>criminology Scientific study of nonlegal aspects of crime, including its  causes and prevention. Criminology originated in the 18th century when  social reformers began to question the use of punishment for retribution  rather than deterrence and reform. In the 19th century, scientific methods  began to be applied to the study of crime. Today criminologists commonly  use statistics, case histories, official records, and sociological field meth�  ods to study criminals and criminal activity, including the rates and kinds  of crime within geographic areas. Their findings are used by lawyers,  judges, probation officers, law-enforcement and prison officials, legisla�  tors, and scholars to better understand criminals and the effects of treat�  ment and prevention.

He served as a deputy from  Sicily in the newly unified Italian parliament (1861-96) and held office  in several leftist governments. As premier (1887-91, 1893-96), he insti�  tuted liberal reforms and later improved the economy but became increas�  ingly repressive.

The conditions are the critical temperature,  the critical pressure, and the critical density. If a closed vessel is filled with  a pure substance, partly liquid and partly vapour, and the average density  equals the critical density, the critical conditions can be achieved. As the  temperature is raised, the vapour pressure increases, and the gas phase  becomes denser while the liquid expands and becomes less dense. At the  critical point, the densities of liquid and vapour become equal, eliminat�  ing the boundary between the two.</p><p>critical theory Marxist inspired movement in social and political phi�  losophy originally associated with the work of the Frankfurt school. Draw�  ing particularly on the thought of Karl Marx and Sigmund Freud, critical  theorists maintain that a primary goal of philosophy is to understand and  to help overcome the social structures through which people are domi�  nated and oppressed. Believing that science, like other forms of knowl�  edge, has been used as an instrument of oppression, they caution against  a blind faith in scientific progress, arguing that scientific knowledge must  not be pursued as an end in itself without reference to the goal of human  emancipation. Since the 1970s, critical theory has been immensely influ�  ential in the study of history, law, literature, and the social sciences.</p><p>Critius and Nesiotes Vkri-shos, , kri-te-9s...,nes-e- , o- l tez\ or Kritios  and Nesiotes (fl. late 5th century bc, Athens, Greece) Greek sculptors.

A graduate of the  College of William and Mary (1807), he became territorial attorney gen�  eral in Illinois (1809). He also served in the U.S. Senate (1817-19, 1835-  40, 1842-48,1855-61), as U.S. attorney general (1840�41,1850-53), and  as governor of Kentucky (1848-50). He is best known for the Crittenden  Compromise. In 1861 he chaired the Frankfort convention of leaders of bor�  der states, which asked the South to reconsider its position on secession.</p><p>Crittenden Compromise Series of compromises in 1860-61  intended to forestall the American Civil War. Sen. John J. Crittenden pro�  posed constitutional amendments that would reenact provisions of the  Missouri Compromise and extend them to the western territories, indemnify  owners of fugitive slaves whose return was prevented by antislavery ele�  ments in the North, allow a form of popular sovereignty in the territories,  and protect slavery in the District of Columbia. The plan was rejected by  president-elect Abraham Lincoln and narrowly defeated in the Senate.</p><p>Crivelli \kre-'vel-le.

All his works  were of religious subjects, done in an elaborate, old-fashioned style remi�  niscent of the linearism of Andrea Mantegna. Characterized by heavy  ornamentation, sharp outlines, and exaggerated facial expressions, his  paintings are closer to the religious intensity of Gothic art than to the  rationalism of the Renaissance.</p><p>croaker See drum</p><p>Croatia \kr6-'a-sh3\ officially Republic of Croatia Country, west-  central Balkans, southeastern Europe.

The central  mountain belt is known for fruit, and the farms of Istria and Dalmatia  produce grapes and olives. The most important industries are food pro�  cessing, wine making, textiles, chemicals, and petroleum and natural gas.  Croatia is a republic with a unicameral legislature; its head of state is the  president, and the head of government is the prime minister. The Croats,  a southern Slavic people, arrived in the 7th century ad and came under  Charlemagne�s rule in the 8th century. They converted to Christianity soon  afterward and formed a kingdom in the 10th century. Croatia retained its  independence under native kings until 1102, when the crown passed into  the hands of the Hungarian dynasty. Nonetheless, even under dynastic  union with Hungary, institutions of separate Croatian statehood were  maintained. The area associated with the name Croatia shifted gradually  north and west as its territory was eroded, first with the loss of Dalmatia  to Venice by 1420 and then as a result of Ottoman conquests in the 16th  century. During the 16th century the remainder of Croatia came under the  rule of the Austrian Habsburgs. In 1867 it became part of the Austro-  Hungarian Empire, with Dalmatia and Istria ruled by Vienna and Croatia-  Slavonia a Hungarian crown land. In 1918, after the defeat of Austria-  Hungary in World War I, Croatia joined other southern Slavic territories  to form the Kingdom of Serbs, Croats, and Slovenes, which was renamed  Yugoslavia in 1929. In World War II an independent state of Croatia was  established by Germany and Italy, embracing Croatia-Slavonia, part of  Dalmatia, and Bosnia and Herzegovina; after the war Croatia was rejoined  to Yugoslavia as a people�s republic. Croatia declared its independence  in 1991, sparking insurrections by Croatian Serbs, who carved out autono�  mous regions with Yugoslav army help; Croatia took back most of these  regions by 1995. With some stability returning, Croatia�s economy began  to revive in the late 1990s and early 21st century.</p><p>Croce Vkro-cha\, Benedetto (b. Feb. 25, 1866, Pescasseroli, Italy�d.

A passionate antifascist, he  helped revive liberal institutions in the years following World War II,  including the Liberal Party, which he led from 1943 to 1952. In 1947 he  founded the Italian Institute for Historical Studies. His philosophical work  has been influential in aesthetics and in studies of Giambattista Vico, which  he helped to revive.

In 1821 he was elected to the Tennessee legislature, winning  popularity through campaign speeches filled with yarns and homespun  metaphors. He won election to the U.S. House of Representatives in 1827,  1829, and 1833. During his first congressional term, Crockett broke with  Andrew Jackson and the new Democratic Party over Crockett�s desire for  preferential treatment of squatters occupying land in western Tennessee.  The Whigs early courted and publicized Crockett in the hope of creating  a popular �coonskin� politician to offset Jackson. In 1834 Crockett was  conducted on a triumphal speech-making tour of Whig strongholds in the  East. From the many stories about him in books and newspapers, there  grew the legend of an eccentric but shrewd �b�ar hunter� and Indian  fighter. In 1835 he went to Texas to join the war against Mexico and was  killed at the Alamo.</p><p>crocodile Any of about a dozen tropical reptile species (family Croc-  odilidae) found in Asia, the Australian region, Africa, Madagascar, and  the Americas. Crocodiles are long-snouted, lizardlike carnivores. Most  feed on fishes, turtles, birds, and small mammals; large individuals may  attack domestic livestock or humans. Crocodiles swim and feed in the  water, floating at the surface to wait for prey, but bask in the sun and  breed on land. They are reputed to be livelier than alligators and more  likely to attack humans. They have a narrower snout than alligators and  a tooth on each side of the jaw that is visible when the jaw is closed.</p><p>crocus Any of about 75 species of low-growing plants, with corms, that  make up the genus Crocus (iris family), native to the Alps, southern Europe,  and the Mediterranean and widely grown for their cuplike blooms in early  spring or fall.

He was named Indian agent  (an official representative to Indian  tribes) for Pennsylvania in the 1740s.  Later, as deputy to William Johnson  (1756-72), he negotiated with tribes  complaining of encroachments on  their land by colonists. In 1765 he  achieved an end to Pontiac�s War.

First discovered in 1868 at the Cro-Magnon rock  shelter in the Dordogne region in southern France, the human skeletons  that came to be called Cro-Magnon are now considered representative of  humans at that time. Cro-Magnons were relatively more robust and pow�  erful than today�s humans, with a somewhat larger brain capacity. The  Cro-Magnons are generally associated with the Aurignacian tool indus�  try and artistic tradition (see Aurignacian culture). Cro-Magnons seem to  have been a settled people, living in caves or primitive huts and lean-tos,  moving only when necessary to find new hunting or because of environ�  mental changes. It is difficult to determine how long the Cro-Magnons  lasted and what happened to them; presumably they were gradually  absorbed into the European populations that came later.</p><p>Cromer, Evelyn Baring, 1st earl of (b. Feb. 26, 1841, Cromer  Hall, Norfolk, Eng.�d. Jan. 29, 1917, London) British administrator in  Egypt. After serving as an army officer (1858-72), he became private sec�  retary to his cousin Lord Northbrook, viceroy of India. In 1877 he went  to Egypt to help resolve Egypt�s financial problems. Named British agent  and consul general in 1883, he instituted a form of government known  as the Veiled Protectorate, whereby he ruled the Egyptian khedives. Egypt  was made financially solvent by 1887, and Cromer�s parsimony and  encouragement of agricultural projects increased its prosperity. Until his  resignation in 1907, he remained the country�s real ruler, profoundly influ�  encing Egypt�s development as a modern state.</p><p>Crompton, Samuel (b.

Sept. 3, 1658, London) English soldier and statesman, lord pro�  tector of the republican Commonwealth of England, Scotland, and Ire�  land (1653-58). He was elected to Parliament in 1628, but Charles I  dissolved that Parliament in 1629 and did not call another for 11 years.  In 1640 Cromwell was elected to the Short and the Long Parliament. When  differences between Charles and Parliament erupted into the English Civil  Wars, Cromwell became one of the leading generals on the Parliamen�  tary side, winning many notable victories, including the Battles of Mar-  ston Moor and Naseby. He was among those who brought the king to trial  and signed his death warrant. After the British Isles were named the  Commonwealth, he served as the first chairman of the Council of State.  In the next few years he fought against the Royalists in Ireland and Scot�  land and suppressed a mutiny inspired by the Levelers. When Charles II  advanced into England, Cromwell destroyed his army at Worcester  (1651), the battle that ended the civil wars. As lord protector, Cromwell  raised his country�s status once more  to that of a leading European power  and concluded the Anglo-Dutch  War. Though a devout Calvinist, he  pursued policies of religious tolera�  tion. He refused the title of king  offered to him by Parliament in  1657. After his death he was suc�  ceeded by his son Richard Cromwell.</p><p>Cromwell, Richard (b. Oct. 4,</p><p>1626�d. July 12, 1712, Cheshunt,</p><p>Hertfordshire, Eng.)

He was a confidential adviser  to Thomas, Cardinal Wolsey, before entering Parliament (1529), where his  abilities attracted the king�s notice. Entering Henry�s service in 1530, he  was chiefly responsible for establishing the Reformation in England, for  the dissolution of the monasteries, and for strengthening the royal admin�  istration. He eventually came into complete control of the government,  though he pretended to be acting on the king�s authority. In 1539 he made  the mistake of inducing Henry to marry Anne of Cleves, which led to his  fall. At his enemies� instigation he was arrested for heresy and treason,  condemned without a hearing, and executed.</p><p>Cronenberg Vkro-non-.borgV David (b. May 15, 1943, Toronto, Ont.,  Can.)

His  books combine sentimentality with social criticism. His first novel, Hat�  ter�s Castle (1931; film, 1941), was an immediate success. His classic  The Stars Look Down (1935; film, 1939) chronicles social injustice in a  mining community. Other works include The Citadel (1937; film, 1938),  The Keys of the Kingdom (1942; film, 1944), The Green Years (1944; film,  1946), The Judas Tree (1961), and A Thing of Beauty (1956).</p><p>Cronkite, Walter (Leland, Jr.) (b.

He was a successful character actor in many plays, including Polonius in  Hamlet (1964, Tony Award), and directed plays such as Hilda Crane  (1950) and The Egghead (1957). Tandy made her Broadway debut in  1930. She was the original Blanche DuBois in A Streetcar Named Desire  (1947, Tony Award). She and Cronyn married in 1942 and acted together  in such successful plays as The Fourposter (1951), A Delicate Balance  (1966), The Gin Game (1977), and Foxfire (1982), the last two of which  earned Tony Awards for Tandy.

Aerial spraying and dusting permit prompt coverage of large areas at the  moment when application of pesticide is most effective and avoid the need  for wheeled vehicles that might damage crops. The technique was greatly  improved in the 1960s with the development of ultra-low-volume appli�  cators, in which concentrated pesticides are distributed in extremely small  amounts. See also spraying and dusting.</p><p>crop rotation Successive cultivation of different crops in a specified  order on the same fields. Some rotations are designed for high immedi�  ate returns, with little regard for basic resources. Others are planned for  high continuing returns while protecting resources. A typical scheme  selects rotation crops from three classifications: cultivated row crops (e.g.,  com, potatoes), close-growing grains (e.g., oats, wheat), and sod-forming,  or rest, crops (e.g., clover, clover-timothy). In general, cropping systems  should include deep-rooting legumes. In addition to the many beneficial  effects on soils and crops, well-planned crop rotations make the farm a  more effective year-round enterprise by providing more efficient handling  of labour, power, and equipment, reduction in weather and market risks,  and improved ability to meet livestock requirements.</p><p>croquet \kro-'ka\ (French dialect for �crook,� �hockey stick�) Game in  which players using mallets drive wooden balls through a series of wick�  ets, or hoops, set out on a lawn.

As a singer with the Paul  Whiteman orchestra in 1927, he  exhibited a mellow �crooning� style  and casual stage manner that proved  highly popular. He appeared in the  early sound film King of Jazz (1931),  and he later had his own radio pro�  gram. By the late 1930s his records  had sold millions of copies. His  recordings of �White Christmas� and  �Silent Night� were among the most  popular songs of the 20th century. In  the 1940s he starred in a popular  radio variety show. His film career  included the seven Road comedies  with Bob Hope and Dorothy Lamour,  beginning with The Road to Sin�  gapore (1940); Going My Way (1944, Academy Award); The Bells of St.  Mary�s (1945); and White Christmas (1954). More than 300 million of  his records have been sold, a total surpassed only by Elvis Presley among  solo artists.</p><p>cross Principal symbol of Christianity, recalling the crucifixion of Jesus.  There are four basic iconogaphic representations: the crux quadrata, or  Greek cross, with four equal arms; the crux immissa, or Latin cross, with  a base stem longer than the other arms; the crux commissa (St. Anthony�s  cross), resembling the Greek letter tau (T); and the crux decussataa (St.  Andrew�s cross), resembling the Roman numeral 10 (X). Tradition holds  that the crux immissa was used for Christ�s crucifixion. Coptic Christians  used the ancient Egyptian ankh. Displaying the cross was not common  before Constantine I abolished crucifixion in the 4th century. A crucifix  shows Christ�s figure on a cross and is typical of Roman Catholicism and  Eastern Orthodoxy. Making the sign of the cross with the hand may be a  profession of faith, prayer, dedication, or benediction. See illustration  opposite.</p><p>Cross River River, western Africa.

Cross  section is expressed in terms of area, and its value is chosen so that, if  the bombarding particle hits a circular target of this size perpendicular to  its path and centred at the nucleus, the given reaction occurs. If it misses  the area, the reaction does not occur. The unit of cross section is the barn,  which equals 10 -24 sq cm. Cross-section values for a given nucleus  depend on the energy of the bombarding particle and the kind of reaction  and are often different from the actual cross-sectional area of the nucleus.</p><p>crossbow Leading missile weapon of the Middle Ages, consisting of a  short bow fixed transversely on a  stock, with a groove to guide the  missile and a trigger to release it. The  missile, known as a bolt, was usually  an arrow or dart. First used in antiq�  uity, it was an important advance in  warfare. Its destructive power came  from its metal bow, which could pro�  pel a bolt with enough velocity to  pierce chain mail and gave it a range  of up to 1,000 ft (300 m). Powerful  and versatile, it remained in use even  after the introduction of the longbow  and firearms and was not discarded  until the 15 th century. It has been  used in modem times to hunt big game.</p><p>cross-country running Long-distance running over open country. It  developed as a competitive event in the mid-19th century. Though origi�  nally included in the revived Olympics, it was dropped after 1924 as not  suitable for summer competition (most cross-country races are held in the  fall or early winter). The first international women�s competition was held  in 1967. Standard distances are 12,000 m (7.5 mi) for men, and 2,000-  5,000 m (1.25-3 mi) for women. Though rules for championship compe�  titions have been established, world records are not kept because of the  varying difficulty of courses.</p><p>cross-country skiing Skiing in open country over rolling, hilly ter�  rain. It originated in Scandinavia as a means of travel as well as recre�  ation. The skies used are longer, narrower, and lighter than those used in  Alpine skiing, and bindings allow more heel movement. The standard  lengths of international races range from 10 to 50 km (6.2-31 mi) for  men and 5 to 30 km (3.1-18.6 mi) for women.

Its numerous varieties grow as shrubs or small trees with bril�  liant, glossy, leathery leaves that can be solid in colour or occur in com�  binations of green, yellow, white, orange, pink, red, crimson, and purple.  Another plant of the same family but of a different genus is purging cro�  ton ( Croton tiglium ), a small tree native to Southeast Asia with seeds that  yield croton oil.</p><p>croup \'krup\ Acute laryngeal inflammation and spasms in young chil�  dren, with harsh cough, hoarseness, and difficulty breathing. Causes  include infection, allergy, and physical irritation of the larynx. Viral croup,  the most common, usually occurs before age 3. It can usually be treated  at home with a cool mist vaporizer. Bacterial croup (epiglottitis) gener�  ally strikes between ages 3 and 7. Swelling of the epiglottis rapidly causes  severe breathing and swallowing difficulty, requiring antibiotics and inser�  tion of a breathing tube.</p><p>Crow North American Plains Indian people of southern Montana, U.S. The  Crow, whose language belongs to the Siouan language stock, were histori�  cally affiliated with the Hidatsa. Historically, they occupied the area around  the Yellowstone River in northern Wyoming and southern Montana. Much  of Crow life revolved around the buffalo and the horse. The Crow were  prominent as middleman traders, trading horses, bows, and other items to  local village Indians in return for guns and metal goods that they carried to  the Shoshone in Idaho. The basic element in Crow religious life was the  supernatural vision, induced by fasting and isolation. The Crow continually  suffered losses from wars with the Blackfoot and Sioux and sided with the  whites in the Indian wars of the 1860s and �70s. In 1868 they accepted a  reservation carved from former tribal lands in southern Montana. Some  9,100 individuals claimed sole Crow descent in the 2000 U.S. census.</p><p>crow Any of more than 20 species of black perching birds (see passe�  rine) of the genus Corvus (family  Corvidae) that are smaller than most  ravens and have a thinner bill. They  are named for the sound of their call.</p><p>Common crows are found in North  America and Eurasia. They eat grain,  berries, insects, carrion, and the eggs  of other birds. Crows may damage  grain crops, but they also eat many  economically harmful insects. At  times tens of thousands roost  together, but most species do not nest  in colonies. Crows are considered  the most intelligent of all birds (tool  use is documented), and pet crows  can be taught to imitate speech.</p><p>Crowe Vkro\, Sir Eyre (Alexander Barby Wichart) (b. July 30,  1864, Leipzig, Ger.�d. April 28, 1925, Swanage, Dorset, Eng.) British  diplomat. In the years before World War I he strongly urged an anti-  German policy, arguing in a 1907 memorandum that Germany aimed at  the domination of Europe, that concessions would only increase its appe�  tite for power, and that the entente with France must not be abandoned.  On July 25, 1914, he urged a show of force by the British navy to fore�  stall war, and when war began a few days later he induced the govern�  ment to seize German vessels in British ports. He served as permanent  undersecretary of state for foreign affairs (1920-25).</p><p>crowfoot See buttercup</p><p>crown gall Disease of plants caused by the bacterium Agrobacterium  tumefaciens. Thousands of plant species are susceptible, including espe�</p><p>cially rose, grape, pome and stone fruits (e.g., apples, peaches), shade and  nut trees, many shrubs and vines, and perennial garden plants. Symptoms  include roundish, rough-surfaced galls, several inches or more in diam�  eter. At first cream-coloured or greenish, they later turn brown or black. As  the disease progresses, affected plants lose vigour and may eventually die.</p><p>crown jewels Ornaments used at the coronation of a monarch and the  formal ensigns of monarchy worn or carried on state occasions, as well  as collections of personal jewelry consolidated by European sovereigns  as valuable assets of their royal houses and the offices they filled. Most  familiar are those of Britain, which include St. Edward�s Crown, the  Royal Sceptre (with the Star of Africa diamond), the Sceptre of Equity  and Mercy, and the Sword of Offering, as well as the coronation ring,  anointing spoon, ampulla (flask), and coronation bracelets. Many collec�  tions of royal jewelry have been assembled, confiscated, and dispersed  over the centuries.</p><p>crown-of-thorns starfish Reddish and heavy-spined starfish ( Acan-  thaster planci) that has 12-19 arms  and is often 18 in. (45 cm) across. It  feeds on the polyps of coral. Begin�  ning c. 1963, its population on Aus�  tralia�s Great Barrier Reef exploded.</p><p>Destruction of coral reefs and islands  was feared, and intensive efforts  were made to kill it off. Since then  other outbreaks have been recorded  throughout the southern Pacific. The  cause of the outbreaks is unknown,  but several factors have been pro�  posed, such as the decimation of the  starfish�s chief predator, the Pacific  triton (a marine snail), by shell col�  lectors. Other factors, including the  runoff of nutrient-rich soil into reef waters as a result of shorefront devel�  opment, have also been implicated. Population fluctuations could also be  a feature of the starfish�s natural ecology, and human influence may alter  these cycles.</p><p>crown vetch Vigorous trailing legume ( Coronilla varia), native to the  Mediterranean but widely grown in temperate areas as a ground cover. It  has femlike leaves and clusters of white to pink flowers. The sturdy roots  are useful in binding the soil of steep slopes and roadside embankments.  As a legume, crown vetch draws nitrogen from the air, trapping it in the  roots, and thus improves soil fertility. It dies back to the crown each fall  in cold areas, resuming growth in spring. Cutting the plant back in the fall  or early spring encourages quick growth.</p><p>crucible Vkrii-so-balN Pot of clay or other refractory material, used from  ancient times as a container for melting metals or other materials. Mod�  em crucibles may be small laboratory utensils for conducting high-  temperature chemical reactions and analyses, or large industrial vessels  for melting and calcining metal, ore, or glass, and may be made of clay,  graphite, porcelain, or a relatively infusible metal.</p><p>crucible process Technique for producing cast or tool steel. It was  invented in Britain c. 1740 by Benjamin Huntsman, who heated small  pieces of carbon steel in a closed fireclay crucible placed in a coke fire.  This was the first process used in Europe in which the temperature  (2,900�F, or 1,600�C) was high enough to melt the steel, producing a  homogeneous metal of uniform composition. After 1870 the Siemens  regenerative gas furnace replaced the coke-fired furnace. Capable of pro�  ducing even higher temperatures, the Siemens furnace had a number of  combustion holes, each holding several crucibles, and heated as many as  100 crucibles at a time. All high-quality tool steel and high-speed steel was  long made by the crucible process. In the 20th century the electric furnace  has replaced it in countries with inexpensive electric power.

He received acclaim for his dramatic roles in The Color  of Money (1986), Rain Man (1988), Born on the Fourth of July (1989),  and Magnolia (1999). His other films include A Few Good Men (1992),  Mission: Impossible (1996), Jerry Maguire (1996), Stanley Kubrick�s Eyes  Wide Shut (1999), and Steven Spielberg�s Minority Report (2002).</p><p>cruise missile Type of low-flying strategic guided missile developed by  the U.S. and the Soviet Union in the 1960s and �70s. The V-l missile was  a precursor. Powered by jet engines, cruise missiles may carry either a  nuclear or a conventional warhead. They are designed to hug the ground,  which makes them hard to detect by radar. They are launched from ships,  submarines, airplanes, and the ground.</p><p>cruiser Warship built for high speed and great cruising radius, smaller  than a battleship but larger than a destroyer. The term originally meant frig�  ates of the sailing era, used to scout for enemy fleets and raid convoys.  After 1880, it was a specific type of armoured warship. By World War II,  cruisers served mainly as floating bases for amphibious assaults and as  protection for aircraft-carrier task forces. Today U.S. cruisers carry  surface-to-air missiles vital to a fleet�s air-defense screen. Nuclear pro�  pulsion has given some cruisers virtually unlimited range.</p><p>Crumb, George (Henry) (b. Oct. 24, 1929, Charleston, W.Va., U.S.)  U.S. composer. Born to musician parents, he studied at the University of  Michigan and from 1965 taught at the University of Pennsylvania. His  style is known particularly for its unusual and hauntingly evocative tim�  bres. Echoes of Time and the River (1967, Pulitzer Prize) and Ancient  Voices of Children (1970) brought him wide fame. His other works include  Madrigals, Books 1-TV (1965-70), Night of the Four Moons (1969), Black  Angels (1970), Makrokosmos I and 7/(1972, 1973), and Star-Child (1977).</p><p>Crumb, R(obert) (b. Aug. 20, 1943, Philadelphia, Pa., U.S.) U.S. car�  toonist. He had no formal art training but was obsessed with drawing as  a child. In 1960 he moved to Cleveland, Ohio, to work for a greeting-card  company. In 1967 he moved to San Francisco and became a prominent  member of the hippie counterculture and a founder of the genre of under�  ground �comix,� satirical magazines that poked fun at U.S. culture. His  often obscene strips with their various obsessive themes, starring such  characters as Fritz the Cat, the Furry Freak Brothers, and Mr. Natural, had  great influence and are still regarded as classics of the genre.</p><p>Crusade, Children's See Children's Crusade  Crusade, Stedinger See Stedinger Crusade</p><p>crusader states Former territories on the Palestine coast taken by the  Christian army during the first of the Crusades. The states were established  as the kingdom of Jerusalem (1099-1187), the principality of Antioch  (1098-1268), the county of Edessa (1098-1144), and the county of Tripoli  (1109-1289). Threats to the states led the pope to call for future crusades.</p><p>Crusades Military expeditions, beginning in the late 11th century, that  were organized by Western Christians in response to centuries of Muslim  wars of expansion. Their objectives were to check the spread of Islam, to  retake control of the Holy Land, to conquer pagan areas, and to recap�  ture formerly Christian territories. The Crusades were seen by many of  their participants as a means of redemption and expiation for sins.  Between 1095, when the First Crusade was launched by Pope Urban II at  the Council of Clermont, and 1291, when the Latin Christians were finally  expelled from their kingdom in Syria, there were numerous expeditions  to the Holy Land, to Spain, and even to the Baltic; the Crusades contin�  ued for several centuries after 1291, usually as military campaigns  intended to halt or slow the advance of Muslim power or to conquer pagan  areas. The Crusaders initially enjoyed success, founding a Christian state  in Palestine and Syria, but the continued growth of Islamic states ulti�  mately reversed those gains. By the 14th century the Ottoman Turks had  established themselves in the Balkans and would penetrate deeper into  Europe despite repeated efforts to repulse them. Crusades were also called  against heretics (the Albigensian Crusade, 1209-29) and various rivals of  the popes, and the Fourth Crusade (1202-04) was diverted against the  Byzantine Empire. Crusading declined rapidly during the 16th century  with the advent of the Protestant Reformation and the decline of papal  authority. The Crusades constitute a controversial chapter in the history  of Christianity, and their excesses have been the subject of centuries of  historiography. Historians have also concentrated on the role the Crusades  played in the expansion of medieval Europe and its institutions, and the  notion of �crusading� has been transformed from a religio-military cam�  paign into a modern metaphor for zealous and demanding struggles to  advance the good (�crusades for�) and to oppose perceived evil (�cru�  sades against�).</p><p>crush injury Effects of compression of the body (e.g., in a building  collapse). Victims with severe chest and abdominal injuries usually die  before help arrives. In survivors, pulse and blood pressure are usually  normal at first, then blood leakage from ruptured vessels causes shock  and local swelling, and blood pressure falls. Release of proteins from  crushed muscles can cause kidney failure a day or two afterwards. Later,  embolisms form from fat droplets that have merged after being squeezed  out of fat cells and bone marrow.</p><p>crust Outermost solid part of the Earth, essentially composed of a range  of igneous and metamorphic rock types. In continental regions, the crust is  made up chiefly of granitic rock, whereas the composition of the ocean  floor corresponds mainly to that of basalt and gabbro. On average, the  crust extends 22 mi (35 km) downward from the surface to the underlying  mantle, from which it is separated by the Mohorovicic discontinuity (the  Moho). The crust and top layer of the mantle together form the lithosphere.</p><p>crustacean Xkros-'ta-shonN Any member of the 45,000 arthropod spe�  cies in the subphylum Crustacea. Distributed worldwide, crustaceans are  distinguished by having two pairs of antenna-like appendages in front of  the mouth and other paired appendages near the mouth that act like jaws.  Most species are marine, including shrimps and barnacles. Some, includ�  ing CRAYFiSHes, live in freshwater habitats; others (e.g., sand fleas, land  crabs, and sow bugs) live in moist terrestrial environments. The typical  adult body is composed of a series of segments (somites) either fused or  linked to each other by flexible areas that form movable joints. The cara�  pace (shell) varies in thickness among species and must be periodically  molted to allow growth. Many species of marine crustaceans are scaven�  gers, and many (including copepods and krill) are significant components  of the diets of larger organisms.

Nov. 12, 1651, San Miguel Nepantla,  Viceroyalty of New Spain�d. April 17, 1695, Mexico City) Mexican  poet, dramatist, scholar, nun, and an early feminist. Bom out of wedlock  to a family of modest means, she was sent to relatives in Mexico City,  where her great intelligence became known to the viceroy. She soon  became a nun, remaining cloistered for the rest of her life. Sor Juana had  one of the largest private libraries in the New World. Her most important  works are the poem �Primero sueno� (1692; �Sor Juana�s Dream�), which  recounts the soul�s quest for knowledge, and the �Respuesta� (1691; �The  Answer�), her defense of women�s right to knowledge.</p><p>cryogenics \ l kri-o- , je-niks\ Study and use of low-temperature phenom�  ena. The cryogenic temperature range is from -238�F (-150�C) to abso�  lute zero. At low temperatures, matter has unusual properties. Substances  that are naturally gases can be liquefied at low temperatures, and metals  lose electrical resistance as they get colder (see superconductivity). Cryo�  genics dates from 1877, when oxygen was first cooled to the point at  which it became a liquid (-297�F, or -183�C); superconductivity was  discovered in 1911. Applications of cryogenics include the storage and  transport of liquefied gases, food preservation, cryosurgery, rocket fuels,  and superconducting electromagnets.</p><p>crypt Subterranean chamber, usually under a church floor. The catacombs  of the early Christians were known  as cryptae, and when churches came  to be built over the tombs of saints  and martyrs, subterranean chapels  were built around the actual tomb.</p><p>As early as the reign of Constantine  I (ad 306-37), the crypt was consid�  ered a normal part of a church.

Cryptography may also refer to the art of  cryptanalysis, by which cryptographic codes are broken. Collectively, the  science of secure and secret communications, involving both cryptogra�  phy and cryptanalysis, is known as cryptology. The principles of cryp�  tography are today applied to the encryption of fax, television, and  computer network communications. In particular, the secure exchange of  computer data is of great importance to banking, government, and com�  mercial communications.

Occur�  ring in both fresh and salt water, cryptomonads contain pigments found  only in red algae and blue-green algae (cyanobacteria). They sometimes  live harmlessly within other organisms. Some species conduct photosyn�  thesis. Others lack pigment-containing structures and eat organic matter,  under certain conditions surviving on minerals alone.</p><p>crystal Any solid material whose atoms are arranged in a definite pattern  and whose surface regularity reflects its internal symmetry. Each of a crys�  tal�s millions of individual structural units (unit cells) contains all the sub�  stance�s atoms, molecules, or ions in the same proportions as in its  chemical formula (see formula weight). The cells are repeated in all direc�  tions to form a geometric pattern, manifested by the number and orienta�  tion of external planes (crystal faces). Crystals are classified into seven  crystallographic systems based on their symmetry: isometric, trigonal,  hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic. Crystals</p><p>are generally formed when a liquid solidifies, a vapour becomes super�  saturated (see saturation), or a liquid solution can no longer retain dis�  solved material, which is then precipitated. Metals, alloys, minerals, and  semiconductors are all crystalline, at least microscopically. (A noncrystal�  line solid is called amorphous.) Under special conditions, a single crystal  can grow to a substantial size; examples include gemstones and some arti�  ficial crystals. Few crystals are perfect; defects affect the material�s elec�  trical behaviour and may weaken or strengthen it. See also liquid crystal.</p><p>crystal lattice Three-dimensional configuration of points connected by  lines used to describe the orderly arrangement of atoms in a crystal. Each  point represents one or more atoms in the actual crystal. The lattice is  divided into a number of identical blocks or cells that are repeated in all  directions to form a geometric pattern. Lattices are classified according  to their dominant symmetries: isometric, trigonal, hexagonal, tetragonal,  orthorhombic, monoclinic, and triclinic. Compounds that exhibit a crystal-  lattice structure include sodium chloride (table salt), cesium chloride, and  boron nitride.

Intrusive igneous  rocks (see intrusive rock) are nearly always crystalline; extrusive igneous  rocks (see extrusive rock) may be partly to entirely glassy. Metamorphic  rocks are also always completely crystalline and are termed crystalline  schists or gneisses. Sedimentary rocks can also be crystalline, such as crys�  talline limestones that precipitate directly from solution; the term is not  generally applied to clastic sediments (made of fragments of preexisting  rock), even though they are formed largely from the accumulation of  crystalline materials.</p><p>crystallography \,kris-t3-'lag-r3-fe\ Branch of science that deals with  discerning the arrangement and bonding of atoms in crystalline solids and  with the geometric structure of crystal lattices. Classically, the optical prop�  erties of crystals were of value in mineralogy and chemistry for the iden�  tification of substances. Modern crystallography is largely based on the  analysis of the diffraction of X-rays by crystals acting as optical gratings.  Using X-ray crystallography, chemists are able to determine the internal  structures and bonding arrangements of minerals and molecules, including  the structures of large complex molecules such as proteins and DNA.</p><p>ctenophore \'te-n3-,for\ or comb jelly Any of nearly 90 species  (phylum Ctenophora) of usually colourless marine invertebrates that have</p><p>Crypt, Canterbury Cathedral (12th  century), England.</p><p>A.F.

He became emperor on the death of Montezuma�s suc�  cessor in 1520, while Hernan Cortes was marching for the second time  on TenochtitlAn, the Aztec capital. He defended the city during a four-  month siege that left most buildings destroyed and few Indians surviving.  Tortured by the Spaniards in an effort to make him reveal the location of  hidden Aztec wealth, his stoicism became legendary. Later Cortes, hear�  ing of a plot against the Spaniards, had Cuauhtemoc hanged.</p><p>Cuba officially Republic of Cuba Island country. West Indies. Located  90 mi (145 km) south of Florida, it comprises the island of Cuba and  surrounding small islands. Area: 42,804 sq mi (110,861 sq km). Popula�  tion (2005 est.): 11,269,000. Capital: Havana. The population is largely  of African-European or African descent; most of the rest are of European  ancestry. Language: Spanish (official). Religions: Christianity (predomi�  nantly Roman Catholic; also Protestant), Santerfa (both formerly discour�  aged). Currency: Cuban peso. The main island of Cuba is 777 mi (1,250  km) long and 19-119 mi (31-191 km) wide. About one-quarter is moun�  tainous, with Turquino Peak at an elevation of 6,476 ft (1,974 m) the  highest peak; the remainder is extensive plains and basins. The climate  is semi tropical. Cuba was the first communist republic in the Western  Hemisphere. It has a centrally planned economy that depends on the  export of sugar and, to a much lesser extent, tobacco and nickel. Its cigars  are considered the world�s best. It is a republic with one legislative house;  its head of state and government is the president. Several Indian groups,  including the Ciboney and the Arawak, inhabited Cuba at the time of the  first Spanish contact. Christopher Columbus claimed the island for Spain in  1492, and the Spanish conquest began in 1511, when the settlement of  Baracoa was founded. The native Indians were eradicated over the suc�  ceeding centuries, and African slaves, from the 18th century until slavery  was abolished in 1886, were imported to work the sugar plantations. Cuba  revolted unsuccessfully against Spain in the Ten Years� War (1868-78);  a second war of independence began in 1895. In 1898 the U.S. entered  the war (see Spanish-American War); Spain relinquished its claim to Cuba,  which was occupied by the U.S. for three years before gaining its inde�  pendence in 1902.

In 1958-59 the communist revolu�  tionary Fidel Castro overthrew its longtime dictator Fulgencio Batista and  established a socialist state aligned with the Soviet Union, abolishing  capitalism and nationalizing foreign-owned enterprises. Relations with the  U.S. deteriorated, reaching a low point with the 1961 Bay of Pigs invasion  and the 1962 Cuban missile crisis. In 1980 about 125,000 Cubans, includ�  ing many officially labeled �undesirables,� were shipped to the U.S. in  the so-called Mariel Boat Lift. When communism collapsed in the  U.S.S.R., Cuba lost important financial backing, and its economy suffered  greatly. The economy gradually began improving in the 1990s with the  encouragement of tourism and the legalization of small businesses and  private employment, though diplomatic relations with the U.S. were not  resumed.</p><p>Cuban missile crisis (1962) Major confrontation between the U.S.  and the Soviet Union over the presence of Soviet nuclear missiles in Cuba.  In October 1962 a U.S. spy plane detected a ballistic missile on a launch�  ing site in Cuba. Pres. John F. Kennedy placed a naval blockade around the  island, and for several days the U.S. and the Soviet Union hovered on the  brink of war. Soviet premier Nikita Khrushchev finally agreed to remove  the missiles in return for a secret commitment from the U.S. to withdraw  its own missiles from Turkey and to never invade Cuba. The incident  increased tensions during the Cold War and fueled the nuclear arms race  between the two countries.

They were later joined by  Juan Gris, Fernand Leger, Robert Delaunay, and others. The name derives  from a review that described Braque�s work as images composed of cubes.  Picasso�s Demoiselles d'Avignon (1907) signaled the new style, which was  inspired by African sculpture and the later paintings of Paul Cezanne. Cub�  ist work emphasized the flat, two-dimensional, fragmented surface of the  picture plane, rejecting perspective, foreshortening, modeling, and chiar�  oscuro in favour of geometric forms. The work made in this style from  1910 to 1912 is often referred to as Analytical Cubism. Paintings executed  during this period show the breaking down, or analysis, of form. Artists  favoured right-angle and straight-line construction and colour schemes that  were nearly monochromatic. After 1912 the phase known as Synthetic  Cubism began. Works from this phase emphasize the combination, or syn�  thesis, of forms in the picture.

They are  found worldwide in temperate and  tropical regions but are most diverse  in the Old World tropics. New World  species are sometimes classified as a  separate family (Coccyzidae) and  include the roadrunner. Cuckoos  range from 6.5 to 36 in. (16 to 90 cm)  long. Most are drab gray, but a few  are partially or completely brightly  coloured or iridescent. Aside from  the European cuckoo�s familiar two-  note call, cuckoos are best known for  their habit of brood parasitism (see  cowbird); their eggs resemble those  of the host species (egg mimicry),  and the adult cuckoo removes one or  more host eggs to ensure that the  substitution is not detected. The  newly hatched cuckoo may also eject  eggs or nestlings.</p><p>cucumber Creeping plant ( Cucu-  mis sativus), of the gourd family  (Cucurbitaceae), or its oblong fruit,  for which it is widely cultivated. It  probably originated in northern  India. The plant is a tender annual with a rough, succulent, trailing stem  and hairy leaves with pointed lobes; the stem bears branched tendrils by  which the plant can suspend itself. The food value of the fruit is low, but  its delicate flavour makes it a popular vegetable for salads and relishes.</p><p>cucumber beetle Any of several leaf beetles (genus Diabrotica) that  are important pests.

June 26, 1688,  Cambridge) English theologian and philosopher. Reared as a Puritan, he  eventually adopted Nonconformist views such as the notion that church  government and religious practice should be individual rather than  authoritarian. He became a leader of the Cambridge Platonists. In ethics,  his outstanding work is A Treatise Concerning Eternal and Immutable  Morality (1731), which was directed against Puritan Calvinism, the the�  ology of Rene Descartes, and the attempt by Thomas Hobbes to reduce  morality to obedience to civil authority. He stressed the natural good or  evil inherent in an event or act, in contrast to the Calvinist-Cartesian  notion of divine law. �Things are what they are,� he wrote, �not by Will  but by Nature.� See also intuitionism; voluntarism.</p><p>Cuellar, Javier Perez de See Javier Perez de Cuellar</p><p>Cuernavaca \,kwer-n3-'va-k3\ City (pop., 2000: 327,162), capital of  Morelos state, south-central Mexico.

The  system was introduced in 1830 by the colonial governor-general Johannes  van den Bosch. In theory, it required that villagers set aside one-fifth of  their land to grow export crops (e.g., coffee, sugar) for the government  and that landless peasants work for one-fifth of the year on government  fields. In fact, much more land and time were required, and the system  proved burdensome. Though roundly criticized in the mid-1850s, the sys�  tem was not abolished until 1870.</p><p>cultural anthropology Branch of anthropology that deals with the  study of culture. The discipline uses the methods, concepts, and data of  archaeology, ethnography, folklore, linguistics, and related fields in its  descriptions and analyses of the diverse peoples of the world. Called  social anthropology in Britain, its field of research was until the mid 20th  century largely restricted to the small-scale (or �primitive�), non-Western  societies that first began to be identified during the age of discovery. Today  the field extends to all forms of human association, from village commu�  nities to corporate cultures to urban gangs. Two key perspectives used are  those of holism (understanding society as a complex, interactive whole)  and cultural relativism (the appreciation of cultural phenomena within  their own context). Areas of study traditionally include social structure,  law, politics, religion, magic, art, and technology.</p><p>Cultural Revolution officially Great Proletarian Cultural  Revolution (1966-76) Upheaval launched by Mao Zedong to renew the  spirit of revolution in China. Mao feared urban social stratification in a  society as traditionally elitist as China and also believed that programs  instituted to correct for the failed Great Leap Forward showed that his col�  leagues lacked commitment to the revolution. He organized China�s urban  youths into groups called the Red Guards, shut down China�s schools, and  encouraged the Red Guards to attack all traditional values and �bourgeois  things.� They soon splintered into zealous rival groups, and in 1968 Mao  sent millions of them to the rural hinterland, bringing some order to the  cities. Within the government, a coalition of Mao�s associates fought with  more moderate elements, many of whom were purged, were verbally  attacked, were physically abused, and subsequently died; leaders Liu Shao-  qi and Lin Biao both died under mysterious circumstances. From 1973 to  Mao�s death in 1976, politics shifted between the hard-line Gang of Four  and the moderates headed by Zhou Enlai and Deng Xiaoping. After Mao�s  death the Cultural Revolution was brought to a close. By that time, nearly  three million party members and countless wrongfully purged citizens  awaited reinstatement. The Cultural Revolution subsequently was repu�  diated in China.

Originally identified with the  Center for Contemporary Cultural Studies at the University of Birming�  ham (founded 1964) and with such scholars as Richard Hoggart, Stuart  Hall, and Raymond Williams, today cultural studies is recognized as a  discipline or area of concentration in many academic institutions and has  had broad influence in sociology, anthropology, historiography, literary  criticism, philosophy, and art criticism. Among its central concerns are the  place of race (or ethnicity), class, and gender in the production of cultural  knowledge.</p><p>culture Integrated pattern of human knowledge, belief, and behaviour  that is both a result of and integral to the human capacity for learning and  transmitting knowledge to succeeding generations. Culture thus consists  of language, ideas, beliefs, customs, taboos, codes, institutions, tools,  techniques, works of art, rituals, ceremonies, and symbols. It has played  a crucial role in human evolution, allowing human beings to adapt the  environment to their own purposes rather than depend solely on natural  selection to achieve adaptive success. Every human society has its own  particular culture, or sociocultural system. Variation among cultures is  attributable to such factors as differing physical habitats and resources;  the range of possibilities inherent in areas such as language, ritual, and  social organization; and historical phenomena such as the development of  links with other cultures. An individual�s attitudes, values, ideals, and  beliefs are greatly influenced by the culture (or cultures) in which he or  she lives. Culture change takes place as a result of ecological, socioeco�  nomic, political, religious, or other fundamental factors affecting a soci�  ety. See also culture contact; sociocultural evolution.</p><p>culture, pure See pure culture</p><p>culture contact Contact between peoples with different cultures, usu�  ally leading to change in one or both systems. Forms of culture contact  traditionally include acculturation, assimilation, and amalgamation.  Acculturation is the process of change in material culture, traditional  practices, and beliefs that occurs when one group interferes in the cultural  system of another, directly or indirectly challenging the latter to adapt to  the ways of the former. Such change has characterized most political con�  quests and expansions over the centuries. Assimilation is the process  whereby individuals or groups of differing ethnicity are absorbed into the  dominant culture of a society�though not always completely. In the U.S.  millions of European immigrants became assimilated within two or three  generations; factors included the upheaval of overseas relocation, the  influences of the public school system, and other forces in American life.  Amalgamation (or hybridization) occurs when a society becomes ethni�  cally mixed in a way that represents a synthesis rather than the elimina�  tion or absorption of one group by another. In Mexico, for example,  Spanish and Indian cultures became increasingly amalgamated over cen�  turies of contact.</p><p>culture hero Mythological figure who secures for humanity the  attributes of culture either in cooperation with or in opposition to the gods.  The culture hero is often an animal or trickster figure, the most common  motif being the animal who steals fire from the gods for the benefit of  humans. In other stories the culture hero is human and must overcome the  opposition of animals. In still others, the culture hero must travel to an  inaccessible place to reach a life-giving or healing tree or other plant;  supernatural animals may assist or obstruct him.

A configuration of such impressions constituted a character,  or sign. Proto-cuneiform signs dating from c. 3200-3000 bc were drawn  rather than impressed and were largely pictographic (see pictography),  though these features were lost as the script evolved. A single cuneiform  sign could be a logogram (an arbitrary representation of a word) or a syl-  labogram (a representation of the sound of a syllable). The first language  to be written in cuneiform was Sumerian (see Sumer). Akkadian began to  be written in cuneiform c. 2350 bc. Later the script was adapted to other  South Asian languages. Cuneiform was slowly displaced in the first mil�  lennium bc by the rise of Aramaic, written in an alphabet script of Phoe�  nician origin.

The ruler and curia made policy decisions (as on war, treaties, finances,  church relations), and under a powerful ruler the curia often became active  as a court of law. Indeed, curiae became so loaded down with judicial  work that they were gradually forced to delegate it to special groups of  judges. In England the Curia Regis (King�s Court) began at the time of  the Norman Conquest (1066) and lasted to about the end of the 13th cen�  tury. It was the germ from which the higher courts of law, the Privy  Council, and the cabinet were to spring.

He served in the U.S. House of  Representatives (1911-14). As Boston�s mayor (1914-18, 1922-26,  1930-34, 1947-50), he dominated the city�s politics for 50 years. He  owed much of his success to serving the needs of Irish immigrants in  exchange for votes. He centralized the powers of patronage in his own  hands and distributed public works jobs so as to retain the loyalty and  support of his working-class electoral base. As mayor, he brought the city  close to bankruptcy by spending enormous sums on parks and hospitals  to satisfy his various constituencies. Unable to win a seat in the Massa�  chusetts delegation to the 1932 Democratic convention, Curley contrived  by means he never explained to be elected a delegate from Puerto Rico.  As governor of Massachusetts (1935-37), he spent New Deal funds lav�  ishly on roads, bridges, and other public works programs. He won a seat  in the House of Representatives in 1942 and was reelected two years later.  His last mayoral term included five months in prison following a convic�  tion for mail fraud; Pres. Harry Truman secured his release and later  granted him a full pardon. His colourful career inspired Edwin  O�Connor�s novel The Last Hurrah (1956).

The object is to deliver the stone clos�  est to the centre (called the house). Each player delivers two stones, which  average 40 lbs (18.1 kg) apiece, often applying a curl to the stone�s tra�  jectory. The player�s teammates use a broom to sweep the ice ahead of  the oncoming stone in order to facilitate a longer slide or to adjust the arc  of the curl. Blocking and knocking out an opponent�s stones are impor�  tant strategies of the sport. Curling originated in Scotland in the early 16th  century.

In general, it is the reciprocal of the radius of the  circle or sphere of best fit to the curve or surface at that point. This notion  of best fit derives from the principle that only one circle can be drawn  though any three points not on the same line. The radius of curvature at  the middle point is approximately equal to the radius of that one circle.  This calculation becomes more exact the closer the points are. The pre�  cise value is found using a limit. Because a straight line can be thought of  as an arc of a circle of infinite radius, its curvature is zero.</p><p>curve In mathematics, an abstract term used to describe the path of a  continuously moving point (see continuity). Such a path is usually gen�  erated by an equation. The word can also apply to a straight line or to a  series of line segments linked end to end. A closed curve is a path that  repeats itself, and thus encloses one or more regions. Simple examples  include circles, ellipses, and polygons.

In the second battle (June 24, 1866), as part of an Italian  effort to acquire Austrian-held Venetia, a disorganized Italian army of  120,000 men, led by Victor Emmanuel II, was defeated by an 80,000-man  Austrian force. Despite its defeats, Italy subsequently obtained Venetia in  the Treaty of Vienna (1866).</p><p>cut glass Glassware characterized by a series of facets, or patterns, cut  into its surface. A marked pattern is roughed out on a glass object with a  revolving abrasive wheel; the pattern is then smoothed by a sandstone  wheel and polished in an acid bath. The Romans introduced a crude form  of glass cutting in the 1st century ad. Modern glass cutting developed in  Germany in the late 17th century with the production of a heavy, colour�  less crystal glass. After Bohemian glass became popular, English and Irish  glassmakers adopted the technique. The prismatic styles of their products,  notably Waterford glass, became popular in the U.S. after 1780.</p><p>Cuthbert, Saint (b. 634/635, probably Northumbria, Eng.�d. March  20, 687, islet of Inner Fame, or House, off Northumbria; feast day March  20) English saint. A shepherd, Cuthbert entered the Northumbrian mon�  astery of Melrose in 651 after receiving a divine vision. When plague  struck 10 years later, he aided the afflicted, reportedly performing  miracles. In 664 he became prior of Lindisfarne, where he instituted a  severe rule. In 676 he retired to Inner Fame, where he devoted himself  to prayer. His efforts to protect birds made him one of the earliest wild�  life conservationists.</p><p>cutthroat trout Black-spotted game fish ( Salmo clarki ) of the salmon  family, found in western North America. The cutthroat trout is named for  the bright red streak beneath its lower jaw. Considered a good table fish,  it strikes at flies, baits, and lures. It reaches a weight of 4 lb (1.8 kg).</p><p>Many cutthroat trout that live in rivers migrate to sea. Like oceanic forms  of other trout species, these fish are called sea trout and may not reenter  freshwater for several years.</p><p>cutting In botany, a plant section originating from the stem, leaf, or root  and capable of developing into a new plant. The cutting is usually placed  in warm, moist sand. Many plants, especially horticultural and garden  varieties, are propagated through cuttings; by the use of new techniques,  many other plants formerly not susceptible to propagation through cut�  tings have more successfully reproduced. The plants that develop from  cuttings are clones. See also graft, layering.</p><p>cutting horse Light saddle horse trained to cut (isolate) livestock, espe�  cially cattle, from herds. Most are quarter horses, with the intelligence,  speed, and ability to make quick starts, stops, and turns. A well-trained  cutting horse can maneuver an animal away from a herd and into a cor�  ner with little direction from a rider or, in some cases, without a rider.</p><p>cuttlefish Any of about 100 species of marine cephalopods in the order  Sepioidea, characterized by a thick,  internal calcium-containing shell  called the cuttlebone. Species range  between 1 and 35 in. (2.5-90 cm) in  length and have a somewhat flat�  tened body bordered by a pair of nar�  row fins. All have eight arms and two  longer tentacles used to capture prey.</p><p>Suction disks are located on the arms  and at the tips of the tentacles.</p><p>Cuttlefish inhabit tropical or temper�  ate coastal waters. They feed mainly  on crustaceans, small fishes, and  each other. They are used by humans  as food, as a source of ink, and for  the cuttlebone, a dietary supplement  for cage birds.</p><p>cutworm Larva of certain species of owlet moths (family Noctuidae).  The cutworm (not a true worm) is a serious insect pest of tobacco and  other crops. Some species attack such plants as corn, grasses, tomatoes,  and beans at night, severing roots and stems near ground level. Other spe�  cies live underground and feed on plant roots.</p><p>Cuvier \kLe-'vya\, Georges (-Leopold-Chretien-Frederic-  Dagobert), Baron (b. Aug. 23, 1769, Montbeliard, France�d. May  13, 1832, Paris) French zoologist and statesman who established the sci�  ences of comparative anatomy and paleontology. As a staff member at the  Museum of Natural History in Paris, he published Le Regne animal dis�  tribute d�apres son organisation (1817), which described his �correlation  of parts� theory, in which every animal organ is functionally related to all  the other organs and that an animal�s functions and habits determine its  anatomic form. Cuvier�s classification of all animals into four completely  discrete groups was a significant advance over the system of Carolus Lin�  naeus. He applied his functional concept to the study of fossils, postulat�  ing that huge land upheavals and floods were the principal factor in the  creation and destruction of species. Though the theory did not last, Cuvi�  er�s work put paleontology on a firm empirical foundation. As Napoleon�s  inspector of public instruction, he helped establish France�s provincial  universities, and he also served as chancellor of the University of Paris.</p><p>Cuyaba River See Cuiaba River</p><p>Cuyahoga V.kl-o-'ho-go, .kl-o-'ho-goV River River, northeastern Ohio,  U.S. It flows past Akron, where it drops into a deep valley and turns north,  emptying into Lake Erie at Cleveland. It is navigable for lake freighters for  only about 5 mi (8 km) of its total length of about 80 mi (130 km). It was  at one time so severely polluted that it caught fire; by the late 1970s, anti�  pollution measures had substantially improved its condition. The Cuya�  hoga Valley National Recreation Area covers about 32,000 acres (12,950  hectares) of river valley between Akron and Cleveland.</p><p>Cuyp VkceipV Aelbert Jacobsz(oon) (baptized Oct. 20, 1620, Dor�  drecht, Neth.�d.

Rising in  Venezuela and flowing through Guyana, it is about 350 mi (560 km) long  and forms the border between Venezuela and Guyana for some 60 mi (100  km). It then flows southeast to join the Mazaruni River before entering  the Essequibo River, near Bartica. Rapids impede navigation, but the river  is important for its alluvial gold and diamonds.</p><p>Cuzco \'kii-sko\ City (pop., 1998 est.: 278,590), south-central Peru. It is  located high in the Andes Mountains at an elevation of about 11,000 ft  (3,300 m). Founded in the 11th or 12th century, it was once the capital  of the vast Inca empire. Spanish conquistador Francisco Pizarro captured  the city in 1533. It suffered major earthquake damage in 1650 and again  in 1950, though many sites have since been restored. Nearby ruins include  an ancient Inca fortress, the city of Machu Picchu, and the Temple of the  Sun. Cuzco�s cathedral (1654) and university (1692) date from the colo�  nial era. The city was designated a UNESCO World Heritage site in 1983.</p><p>Cwmbran \kum-'bran\ Town (pop., 1991: 46,020), southeastern Wales.  One of 32 new towns established in Britain after World War II to relieve  congestion and encourage development, Cwmbran was inaugurated in  1949 in an area of small and decaying industrial villages. Its industries  include automobile-parts production.</p><p>cyanide VsI-9- l nId\ Any chemical compound containing the combining  group CN. Ionic (see ion; ionic bond) and organic cyanide compounds dif�  fer in chemical properties, but both are toxic, especially the ionic ones.  Cyanide poisoning inhibits cells� oxidative (see oxidation-reduction) pro�  cesses; its action is extremely rapid, and an antidote must be given  promptly. Cyanides occur naturally in certain seeds (e.g., apple seeds, wild  cherry pits). Cyanides, including hydrogen cyanide (HCN, or hydrocya�  nic acid), are used industrially in the production of acrylic fibres, syn�  thetic rubbers, and plastics as well as in electroplating, case-hardening of  iron and steel, fumigation, and concentration of ores.</p><p>cyanide process or MacArthur-Forrest process Method of  extracting silver and gold from their ores by dissolving them in a dilute  solution of sodium cyanide or potassium cyanide. The process�invented  in 1887 by the Scottish chemists John S. MacArthur, Robert W. Forrest,  and William Forrest�includes contacting the finely ground ore with the  cyanide solution, separating unwanted solids from the clear solution, and  recovering the precious metals from the solution by precipitation with zinc  dust.</p><p>cyanite See kyanite</p><p>cyanobacteria X.sI-o-.no-bak-'tir-e-oV or blue-green algae Any of</p><p>a large group of prokaryotic, mostly photosynthetic organisms. Though  classified as bacteria, they resemble the eukaryotic algae in many ways,  including some physical characteristics and ecological niches, and were  at one time treated as algae. They contain certain pigments, which, with  their chlorophyll, often give them a blue-green colour, though many spe�  cies are actually green, brown, yellow, black, or red. They are common  in soil and in both salt and fresh water, and they can grow over a wide  range of temperatures, from Antarctic lakes under several metres of ice  to Yellowstone National Park�s hot springs in the U.S. Cyanobacteria are  often among the first species to colonize bare rock and soil. Some are  capable of nitrogen fixation; others contain pigments that enable them to  produce free oxygen as a by-product of photosynthesis. Under proper con�  ditions (including pollution by nitrogen wastes) they can reproduce explo�  sively, forming dense concentrations called blooms, usually coloured an  opaque green. Cyanobacteria played a large role in raising the level of  free oxygen in the atmosphere of early Earth.</p><p>Cybele See Great Mother of the Gods</p><p>cybercrime also known as computer crime Any use of a computer  as an instrument to further illegal ends, such as committing fraud, traf�  ficking in child pornography and intellectual property, stealing identities,  or violating privacy. Cybercrime, especially through the Internet, has  grown in importance as the computer has become central to commerce,  entertainment, and government. The international nature of cybercrimes  has led to international cyberlaws.</p><p>cyberlaw Body of law bearing on the world of computer networks,  especially the Internet. As traffic on the Internet has increased, so have the</p><p>number and kind of legal issues surrounding the technology. Hotly  debated issues include the obscenity of some on-line sites, the right of pri�  vacy, freedom of speech, regulation of electronic commerce, and the appli�  cability of COPYRIGHT laws.</p><p>cybernetics Science of regulation and control in animals (including  humans), organizations, and machines when they are viewed as self-  governing whole entities consisting of parts and their organization. It was  conceived by Norbert Wiener, who coined the term in 1948. Cybernetics  views communication and control in all self-contained complex systems  as analogous. It differs from the empirical sciences (physics, biology, etc.)  in not being interested in material form but in organization, pattern, and  communication in entities. Because of the increasing sophistication of  computers and the efforts to make them behave in humanlike ways, cyber�  netics today is closely allied with artificial intelligence and robotics, and it  draws heavily on ideas developed in information theory.</p><p>eye ad \'s!-kod\ Any of the palmlike woody plants that constitute the  order Cycadales, containing four families: Cycadaceae, Zamiaceae, Stan-  geriaceae, and Boweniaceae. Cycads have crowns of large, feathery com�  pound leaves and cones at the ends of their branches. Some have tall,  unbranched, armourlike trunks; others have partially buried stems with  swollen trunks. Slow-growing cycads are used as ornamental conserva�  tory plants, but some survive outdoors in temperate regions. The stems  of some cycads yield starch that is edible if thoroughly cooked. The young  leaves and seeds of others also are edible.</p><p>Cyclades VsI-klo-.dezX Greek Kikladhes \ke-'kla-thes\ Group of  about 30 islands, southern Aegean Sea. They cover a land area of 976 sq  mi (2,528 sq km) and constitute the Cyclades department of Greece, which  has its capital at Ermoupolis. Their name refers to the ancient tradition  that they formed a circle around the sacred island of Delos. The chief  islands are Andros, Tfnos, Naxos, Amorgos, Melos, Paros, Syros, Kea,  Kfthnos, Serifos, Ios, and Thira. They were the centre of a Bronze Age  culture�the Cycladic, noted for its white marble idols�and later  belonged to the Mycenaean culture in the 2nd millennium bc. Colonized  by Ionians in the 10th-9th century bc, they later were successively held  by Persians, Athenians, Ptolemaic Egyptians, and Macedonians. Ruled by  Venice after the eai'ly 13th century ad, the islands fell to the Turks at dif�  ferent times during the 16th to 18th centuries. They became part of Greece  in 1829. The economy is now based on tourism and on the export of wine,  hides, pottery, and handicrafts.</p><p>cyclamen VsI-klo-monX Any of about 15 species of flowering perennial  herbaceous plants that make up the genus Cyclamen, in the primrose fam�  ily (Primulaceae), native to the Middle East and southern and central  Europe. The florist�s cyclamen (C. persicum), the best-known species, is  an indoor plant cultivated for its attractive white to pink to deep red flow�  ers. Long-stalked, rounded, or kidney-shaped leaves, often variously  marked, grow from the base of the plant, which has no aboveground stem.  Solitary flowers grow on stalks less than 12 in. (30 cm) tall.</p><p>cycling Use of the bicycle in competitive sport or in recreation. The clas�  sic professional races are held mainly in Europe; the first was held in Paris  in 1868. There are basically two types of race: road races and track races.  The first U.S. cycling competition, a six-day race, was held in 1891. Six-  day racing was reintroduced to Europe as a two-man team event in the  20th century, but it has largely died out in the U.S. The first Tour de France,  the premier race, was held in 1903. Cycling has been part of the Olym�  pics since the first modern games in 1896. Events include a variety of  open-road and circuit races for both men and women.</p><p>cyclone Any large system of winds that circulates about a centre of low  atmospheric pressure in a counterclockwise direction north of the Equa�  tor and in a clockwise direction south of it. Cyclones that occur in the  mid- and high latitudes are known as extratropical cyclones; they are fre�  quently preceded by thickening and lowering clouds, followed by pre�  cipitation. Cyclones that form in the lower latitudes are known as tropical  cyclones; smaller than extratropical cyclones, they tend to be more vio�  lent and can cause considerable damage (see tropical cyclone). Wind sys�  tems that circulate around a high-pressure centre in directions opposite to  that of cyclones are known as anticyclones.</p><p>Cyclops \'sl-,klaps\ In Greek mythology, any of several one-eyed giants.  In the Odyssey, the Cyclopes were cannibals who lived in a faraway land  (traditionally Sicily). Odysseus was captured by the Cyclops Polyphemus,  but he escaped being devoured by blinding the giant. According to Hesiod,</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>500 i cyclotron &#x25BA; Cyprus</p><p>there were three Cyclopes (Arges, Brontes, and Steropes) who forged  thunderbolts for Zeus.

Apollo destroyed them after one of their thunderbolts  killed Asclepius.</p><p>cyclotron VsI-klo-.traM Particle accelerator that accelerates charged  atomic or subatomic particles in a constant magnetic field. It consists of two  hollow semicircular electrodes, called dees, in a large evacuated cylindri�  cal box. An alternating electric field between the dees continuously accel�  erates the particles from one dee to the other, while the magnetic field  guides them in a circular path. As the speed of the particles increases, so  does the radius of their path, and the particles spiral outward. In this man�  ner, a cyclotron can accelerate protons to energies of up to 25 million  electron volts.</p><p>Cydones VsI-'do-nezV, Demetrius (b. c. 1324, Thessalonica, Byzan�  tine Empire�d. c. 1398, Crete) Byzantine humanist scholar, statesman,  and theologian. After studying under a Greek scholar, he made Greek  translations of St. Augustine and St. Thomas Aquinas. He was twice prime  minister of the Byzantine empire (1369-83, 1391-96). An academy of  Greek culture that he established in Venice in 1390 diffused Greek thought  throughout Italy, stimulating the Italian Renaissance. A convert to Latin  Catholicism, he worked unsuccessfully for East-West Christian unity; in  his Symbouleutikoi (�Exhortations�) he vainly encouraged the Byzantine  people to unite with the Latins against the Turks. He is considered the  most brilliant Byzantine writer of the 14th century.</p><p>Cygnus Vsig-nosV A Radio-emitting galaxy lying in the constellation  Cygnus, about 700 million light-years from Earth. It is the brightest cos�  mic source of radio waves in the sky and the first radio galaxy to be  detected. Because of its peculiar divided appearance, it was once thought  to be two galaxies colliding. Astronomers now believe it to be a single  galaxy with a large black hole at its core; emanating from this central  region are two opposing jets of hot gas that end in radio- and X-ray-  emitting lobes called "hot spots." See also active galactic nucleus.</p><p>cylinder See piston and cylinder</p><p>cylinder seal Small stone cylinder engraved in intaglio on its surface  to leave impressions when rolled on wet clay. It first appeared c. 3400-  2900 bc and is considered to be one of the finest artistic achievements of  Mesopotamia. The earliest examples used geometric or animal patterns;  later seals incorporated the owner�s name and depicted a variety of motifs.  They were used to mark personal property and make documents legally  binding. The seals were adopted in Egypt and the Indus civilization.</p><p>cymbal Percussion instrument consisting of a circular metal plate that is  struck with a drumstick or two such  plates that are struck together. They  were used, often ritually, in Assyria,</p><p>Israel (from c. 1100 bc), Egypt, and  other ancient civilizations, spread to  East Asia, and reached Europe by the  13th century ad. Western orchestral  cymbals derive from those used in  the Turkish military bands in vogue  in 18th-century Europe. Though  Asian cymbals are often flat. Middle  Eastern and Western cymbals usually  have a central concave dome, or  boss, so that only the edges touch  when they are clashed. The finest  cymbals have long been manufac�  tured in Turkey by means of closely  guarded techniques. In popular  music, cymbals are not clashed  manually; instead, a cymbal sus�  pended on a sticklike stand may be  brushed or struck, and horizontal �hi-hat� cymbals are clashed lightly by  use of a pedal mechanism.</p><p>Cynewulf or Kynewulf \'kin-3-,wulf\ or Cynwulf Vkin-,wulf\ (fl.  9th century ad, Northumbria or Mercia) Anglo-Saxon poet. He is the author  of four Old English poems from late 10th-century manuscripts: Elene,  about St. Helena; The Fates of the Apostles, on the mission and death of  each Apostle; The Ascension, part of a trilogy by different authors; and Juli�  ana, a life of St. Juliana. Nothing is known of the poet outside of the text;</p><p>its evidence suggests he was a learned cleric of Northumbria or Mercia.  Runic characters woven into the text are thought to spell his name.</p><p>Cynics \'si-niks\ Greek philosophical sect that flourished from the 4th  century bc to the 6th century ad. Antisthenes (c. 445-365 bc), a disciple  of Socrates, is considered the founder of the movement, but Diogenes of  Sinope was its paradigm. Named principally for their meeting place, the  Cynosarges, the Cynics considered virtue�including a life of poverty and  self-sufficiency and the suppression of desires�to be the sole good, but  they were distinguished more for their unconventional manners and way  of life than for any system of thought. The Cynics influenced the devel�  opment of Stoicism.</p><p>cypress Any of about 20 species of ornamental and timber evergreen  conifers constituting the genus  Cupressus of the family Cupres-  saceae, which includes more than  130 species found throughout the  world. The leaves are usually paired  or in threes and are small and scale�  like. A few of the many economi�  cally important genera in the cypress  family are Cupressus, Thuja (arbor-  VlTAE), Calocedrus (incense cedar),  and Juniperus (juniper). Arborvitae,  cypress, and juniper are especially  important as timber sources or orna�  mentals. They also contain useful  oils, resins, and tannins.</p><p>cypress, bald See bald cypress</p><p>Cyprian Vsip-re-onV Saint Latin  Tnascius Caecilius Cyprianus</p><p>(b. c. 200, Carthage�d. Sept. 14,</p><p>258, Carthage; Western and Eastern  feast day September 16; Anglican  feast day September 26) Early Chris�  tian theologian and Church Father. He converted to Christianity c. 246  and within two years was elected bishop of Carthage. In 250 he went into  hiding to escape the Decian persecution, when many Christians aposta�  tized. The following year he returned; bishops in council supported his  assertions that the church could remit the sin of apostasy, that bishops in  council had final disciplinary authority, and that even unworthy laity must  be accepted. In disputes with the bishop of Rome, Cyprian asserted that  the people and their bishop constituted the church, that there was no  �bishop of bishops� in Rome, that all bishops equally possessed the Holy  Spirit, and that their consensus expressed the church�s unity. He was mar�  tyred under Valerian.</p><p>Cyprus officially Republic of Cyprus Island and country, eastern  Mediterranean Sea. Area: 3,572 sq mi (9,251 sq km). Population (2005  est.): 968,000 (whole island). Capital: Nicosia. Cyprus is currently divided  into two de facto states. The Republic of Cyprus, the internationally rec�  ognized government, occupies the southern two-thirds of the island. Its  population (2005 est.: 747,000) is predominantly Greek. Languages:  Greek, Turkish (both official). Religion: Christianity (predominantly East�  ern Orthodox). Currency: Cyprus pound. The Turkish Republic of North�  ern Cyprus occupies the northern third of the island. Its population (2005  est.: 221,000) is overwhelmingly Turkish. Languages: Turkish (official),  English. Religion: Islam. Currency: Turkish lira. The third largest island in  the Mediterranean, Cyprus lies about 40 mi (65 km) off the southern coast  of Turkey. It is largely mountainous, with a fertile heartland and coastal  plains. Mount Olympus is its highest peak, 6,401 ft (1,951 m) above sea  level. The climate is Mediterranean. Cyprus has a free-enterprise economy  based mainly on trade and manufacturing, and it ranks high in the world  in merchant shipping. The internationally recognized government is a  multiparty republic with a unicameral legislature; its head of state and  government is the president. Cyprus was inhabited by the early Neolithic  Period; by the late Bronze Age it had been visited and settled by Mycenae-  ans and Achaeans, who introduced Greek culture and language, and it  became a trading centre. By 800 bc Phoenicians had begun to settle there.  Ruled over the centuries by the Assyrian, Persian, and Ptolemaic empires,  it was annexed by the Roman Republic and Empire in 58 bc. It was part of  the Byzantine Empire in the 4th-12th centuries ad. It was conquered by  the English king Richard I (the Lionheart) in 1191.

Though his mother belonged to the ruling Bacchiadae dynasty, clan  members attempted to kill him at birth because his father was an outsider.  When he grew up, he overthrew them and set up the first tyrant dynasty.  He was encouraged in his quest for power by the oracle at Delphi. He  founded colonies in northwestern Greece, administering them through his  bastard sons, including his successor, Periander. Though he achieved  power through demagoguery, he was reputedly so popular that he did not  need a bodyguard.</p><p>Cyrano de Bergerac Vsir-o-.n  March 6, 1619, Paris, France�d.

He wrote plays as well as fantastical  works combining science-fantasy  and political satire that inspired such  later writers as Jonathan Swift. He  became the basis of many romantic  legends, including Edmond Rostand�s  play Cyrano de Bergerac (1897), in  which he is portrayed as a gallant  and brilliant but shy and ugly lover,  with a remarkably large nose (which  in fact he had).</p><p>i-do-.ber-zho-�rakV Savinien (b.</p><p>Cyrenaica or Cirenaica \,sir-o-  �na-9-k3\ Northeastern region of  present-day Libya.

Though the elder Aristippus (c. 435-366 bc), a pupil of Socrates, is gen�  erally recognized as its founder, the school flourished only in the late 4th  century and early 3rd century bc. The Cyrenaics held that the only good  is the pleasure of the moment; the good life thus consists of the pursuit  of such pleasures. The doctrines of the later Cyrenaics were eventually  incorporated into Epicureanism.</p><p>Cyrene \sl-'re-ne\ Ancient city, North Africa. Located in modern-day  Libya, it was founded c. 630 bc by a  group of emigrants from the Aegean  island of Thira. Their leader, Battus,  became the first king; his dynasty  ruled until c. 440 bc. Under the aegis  of Ptolemaic Egypt (from 323 bc),</p><p>Cyrene became one of the great  intellectual centres of the Classical  world, boasting such scholars as Era�  tosthenes and Aristippus, founder of  the Cyrenaics. Taken by the Romans  in 96 bc, it later declined and, with  the Arab conquest of ad 642, ceased  to exist. Areas of the old city have  been excavated, revealing impres�  sive ruins.</p><p>Cyril and Methodius Vsir-ol...  mi-'tho-de-osV Saints (respectively b. c. 827, Thessalonica,  Macedonia�d. Feb. 14, 869, Rome; b. c. 825, Thessalonica�d. April 6,  884, Moravia; feast day for both, Western church February 14; Eastern  church May 11) Brothers who Christianized the Danubian Slavs. They  began missionary work among the Slavs of Moravia in 863. Gifted schol�  ars and linguists, they translated the holy scriptures into the language later  known as Old Church Slavic (or Slavonic) and are credited with invent�  ing the Glagolithic alphabet (see Cyrillic alphabet). In 868 they traveled to  Rome to defend the use of a Slavic liturgy. When Cyril died, Methodius  returned to Moravia as an archbishop. Known as the �apostles to the  Slavs,� the two brothers influenced the religious and cultural development  of all Slavic peoples.</p><p>Cyril of Alexandria, Saint (b. c. 375�d. June 27, 444; Western  feast day June 27; Eastern feast day June 9) Christian theologian and  bishop. He became bishop of Alexandria in 412. Zealously orthodox, he  closed the churches of the Novatians, a heterodox sect, and expelled the  Jews from Alexandria. His greatest doctrinal conflict was with Nestorius  over the nature of Jesus; Cyril emphasized the unity of Jesus� divine and  human natures while Nestorius emphasized their distinctness. Cyril con�  demned Nestorius at the Council of Ephesus (431), only to be condemned  himself by bishops who supported Nestorius. Eventually Nestorius was  declared a heretic and a compromise on Christ�s nature restored peace to  the church (433).</p><p>Cyril of Jerusalem, Saint (b. c. 315, Jerusalem�d. 386?, Jerusa�  lem; feast day March 18) Early leader of the Christian church. He became  bishop of Jerusalem c. 350. He was exiled three times by the Arians but  was suspected by the strictly orthodox many years later, at the Council  of Constantinople (381), for his association with moderate Arians. He  anticipated the doctrine of transubstantiation in his writings and promoted  Jerusalem as a pilgrimage centre. He was named a Doctor of the Church  in 1883.</p><p>Cyrillic \s9-'ril-ik\ alphabet Alphabet used for Russian, Serbian (see  Serbo-Croatian language), Bulgarian and Macedonian, Belarusian, Ukrai�  nian, and many non-Slavic languages of the former Soviet Union, as well  as Khalka Mongolian (see Mongolian language). The history of the Cyril�  lic alphabet is complex and much disputed. It is clearly derived from 9th-  century Greek uncial capital letters, with the non-Greek letters probably  taken from the Glagolitic alphabet, a highly original alphabet in which  (along with Cyrillic) Old Church Slavonic was written. A commonly held  hypothesis is that followers of Sts. Cyril and Methodius developed Cyril�  lic in the southern Balkans around the end of the 9th century.

The grandson of Cyrus I (fl. late 7th century bc),  he came to power by overthrowing his maternal grandfather, the king of  the Medes. The empire he developed was thenceforth centered on Persia  and included Media, Ionia, Lydia, Mesopotamia, Syria, and Palestine.  Cyrus conquered by diplomacy as well as by force. The subject of a rich  legend in Persia and Greece (recorded by Xenophon and others), he was  called the father of his people. He appeal's in the Bible as the liberator of  the Jews held captive in Babylon. He died battling nomads in Central Asia.  His legacy is the founding not only of an empire but of a culture and  civilization that continued to expand after his death and lasted for two  centuries. He exerted a strong influence on the Greeks and Alexander the  Great. Awarded heroic qualities in legend, he has long been revered by  Persians almost as a religious figure. In 1971 Iran celebrated the 2,500th  anniversary of his founding of the monarchy.</p><p>cyst \'sist\ Enclosed sac within body tissues. It has a distinct membrane  and generally contains liquid. Most cysts are benign, but several kinds  may be malignant or precancerous. Benign cysts often press on nearby  organs and require removal. Formed by overproduction of epithelium  (surface tissue of anatomical structures), cysts may become detached from  surrounding structures and move freely. They can contain natural secre�  tions, abnormal breakdown products, or, in infections, bacteria, larval  parasites, and microbial products. Some organs, including the kidney,  liver, and breast, can become filled with cysts as a result of cystic diseases  that may be dangerous or may hide more serious diseases. See also tumour.</p><p>cysteine \'sis-t3-,en\ Sulfur-containing nonessential amino acid. In pep�  tides and proteins, the sulfur atoms of two cysteine molecules are bonded  to each other to make cystine, another amino acid. The bonded sulfur  atoms form a disulfide bridge, a principal factor in the shape and func�  tion of skeletal and connective tissue proteins and in the great stability of  structural proteins such as keratin.</p><p>cystic fibrosis (CF) Vsis-tik-fi-'bro-s3s\ or mucoviscidosis</p><p>V.myu-ko-.vis-o-'do-sosV Inherited metabolic disorder characterized by  production of thick, sticky mucus. It is recessive (see recessiveness) and  the most common inherited disorder (about 1 per 2,000 live births) in  those of European ancestry. Concentrated mucous secretions in the lungs  plug the bronchi, making breathing difficult, promoting infections, and  producing chronic cough, recurrent pneumonia, and progressive loss of  lung function, the usual cause of death. The secretions interfere with  digestive enzymes and block nutrient absorption. Abnormally salty sweat  is the basis for diagnosis of cystic fibrosis. Treatment includes enzyme  supplements, a diet high in calories, protein, and fat, vigorous physical  therapy, and antibiotics. Persons with cystic fibrosis once seldom survived  beyond childhood; now more than half reach adulthood, though males are  usually sterile.</p><p>cystitis \sis-'tl-t3s\ Inflammation of the urinary bladder (see urinary sys�  tem). Infections with bacteria, viruses, fungi, or parasites usually spread  from nearby sites. Symptoms include burning pain during and right after  urination, unusually urgent or frequent urination, and lower back pain.  Women, with a shorter urethra than men, are more susceptible to cystitis,  most cases resulting from E. coli bacteria from the rectum. Acute cysti�  tis, usually bacterial, causes swelling, bleeding, small ulcers and cysts,  and sometimes abscesses. Recurrent or persistent infection can lead to  chronic cystitis, with bladder-wall thickening. Diagnosis is made by find�  ing bacteria or other organisms in the (normally sterile) urine. It is treated  with drugs or surgery.</p><p>cytochrome Vsi-to-.kroirA Any of a group of cell proteins (hemopro-  teins) that serve a vital function in the transfer of energy within cells.  Hemoproteins are linked to a nonprotein, iron-bearing component (a heme  group), which can undergo the reversible oxidation-reduction reactions that  yield energy for the cell. Cytochromes are subdivided into three classes  depending on what wavelengths of light they absorb. At least 30 differ�  ent cytochromes have been identified.</p><p>cytology \si-'ta-l3-je\ Study of cells. Its earliest phase began with Rob�  ert Hooke�s microscopic investigations of cork in 1665, during which he  introduced the term cell to describe dead cork cells. Mathias Jacob</p><p>Schleiden (in 1838) and Theodor Schwann (1839) were among the first to  state clearly that cells are the fundamental units of both plants and ani�  mals. This pronouncement (the cell theory) was confirmed and elaborated  by a series of discoveries and interpretations. In 1892 Oscar Hertwig  (1849-1922) suggested that processes at the organism�s level are reflec�  tions of cellular processes, thus establishing cytology as a separate branch  of biology. See also physiology.</p><p>cytomegalovirus (CMV) Any of several viruses in the herpes family.  Active infection produces enlarged cells enclosing foreign matter. Most  prevalent in crowded, poor communities, it is transmitted by sexual con�  tact or infected body fluids. It rarely causes serious illness in healthy  adults; however, it can lead to serious consequences, including blindness,  in those with depressed immune systems. In newborns, even without  spleen and liver enlargement (10% of cases), CMV is the most common  infection and a major cause of congenital deafness; it may also induce  retardation and blindness. There is no effective treatment.</p><p>cytoplasm VsI-to-.pla-zomV Portion of a eukaryotic cell outside the  nucleus. The cytoplasm contains all the organelles (see eukaryote). The  organelles include the mitochondria, chloroplasts, endoplasmic reticulum,  Golgi apparatus, lysosomes, and peroxisomes. The cytoplasm also contains  the cytoskeleton and the cytosol (the fluid mass that surrounds the vari�  ous organelles).</p><p>cytosine Vsl-t3-,sen\ Organic compound of the pyrimidine family, often  called a base, consisting of a single ring, containing both nitrogen and  carbon atoms, and an amino group. It occurs in combined form in nucleic  acids and several coenzymes. In DNA its complementary base is guanine.  It or its corresponding nucleoside or nucleotide may be prepared from DNA  by selective techniques of hydrolysis.</p><p>cytoskeleton \'sl-t3-,ske-l3-t�n\ System of microscopic filaments or  fibres, present in the cytoplasm of eukaryotic cells (see eukaryote), that  organizes other cell components, maintains cell shape, and is responsible  for cell locomotion and for movement of the organelles within it. Three  major types of filaments make up the cytoskeleton: actin filaments, micro�  tubules, and intermediate filaments. Actin filaments occur as constantly  changing bundles of parallel fibres; they help determine cell shape, help  the cell adhere to surfaces, help the cell move, and assist in cell division  during mitosis. Intermediate filaments are very stable structures that form  the cell�s true skeleton; they anchor the nucleus within the cell and give  the cell its elastic properties.</p><p>czar See tsar</p><p>Czartoryski family \char-to-'ris-ke\ Leading noble family of Poland  in the 18th century, known as the Familia. It first achieved widespread  power through the efforts of Prince Michal Fryderyk Czartoryski (1696�  1775) and his brother August. The Familia, which sought the enactment  of constitutional reforms, attained the height of its influence in the court  of Augustus III. The family estate at Pulawy was confiscated in 1794, dur�  ing the third Partition of Poland. However, the Familia continued to wield  significant power, notably through the princes Adam Kazimierz Czarto�  ryski (1734-1823), a patron of the arts, and Adam Jerzy Czartoryski  (1770-1861), who worked for the restoration of Poland.</p><p>Czech language formerly Bohemian language West Slavic lan�  guage spoken by some 12 million people in the historical regions of  Bohemia, Moravia, and southwestern Silesia, all now in the Czech Repub�  lic, and in emigre communities, including perhaps a million speakers in  North America. The earliest Old Czech texts date from the late 13th cen�  tury. The distinctive orthographic system of Czech, which adds diacritics  to letters of the Latin alphabet to denote consonants that did not exist in  Latin and to mark vowel length, was introduced in the early 15th century  and is associated with the religious reformer Jan Hus. The system was  later adopted by other Slavic languages that use the Latin alphabet, includ�  ing Slovak, Slovene, and Croatian (see Serbo-Croatian language). When  Czech was revived as a literary language in the early 19th century, Josef  DoBROVSKy based his codification of the language largely on the norms of  16th-century Czech, as exemplified in the Kralice Bible (1579-93), an  authoritative translation. This decision has resulted in a wide gulf between  Standard Czech, the literary language, and Common Czech, the spoken  language.</p><p>Czech Republic formerly (1918-92, with Slovakia) Czechoslova�  kia Country, central Europe. Area: 30,450 sq mi (78,866 sq km). Popu�  lation (2005 est.): 10,221,000. Capital: Prague. Czechs make up nine-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Czerny &#x25BA; Czestochowa i 503</p><p>tenths of the population; Slovaks and  Moravians are the largest minorities. Lan�  guage: Czech (official). Religion: Chris�  tianity (predominantly Roman Catholic,  also other Christians, Protestant). Cur�  rency: koruna. The landlocked country is dominated by the Bohemian  Massif, a ring of mountains rising to 5,256 ft (1,602 m) at Mount Snezka  to encircle the Bohemian Plateau. The Morava River valley, known as the</p><p>Moravian Corridor, separates the Bohemian Massif from the Carpathian  Mountains. Woodlands are a characteristic feature of the Czech landscape;  most regions have a moderate oceanic climate. The economy has been  privatized since the collapse of communism and is now largely market-  oriented. The Czech Republic is a multiparty republic with two legisla�  tive houses; its chief of state is the president, and the head of government  is the prime minister. Until 1918 its history was largely that of Bohemia.  In that year the independent republic of Czechoslovakia was bom through  the union of Bohemia and Moravia with Slovakia. Czechoslovakia came  under the domination of the Soviet Union after World War II, and from  1948 to 1989 it was ruled by a communist government. Its growing politi�  cal liberalization was suppressed by a Soviet invasion in 1968 (see Pra�  gue Spring). After communist rule collapsed in 1989-90, separatist  sentiments emerged among the Slovaks, and in 1992 the Czechs and Slo�  vaks agreed to break up their federated state. At midnight on Dec. 31,  1992, Czechoslovakia was peacefully dissolved and replaced by two new  countries, the Czech Republic and Slovakia, with the region of Moravia  remaining in the former. In 1999 the Czech Republic joined NATO, and  in 2004 it became a member of the European Union.</p><p>Czerny \'cher-ne\, Karl (b. Feb. 20, 1791, Vienna, Austria�d.

A brilliant pianist, he later became a famous piano  teacher; his students included Sigismond Thalberg (1812-71) and Franz  Liszt. Though he was a prolific composer, he is known today almost exclu�  sively for his hundreds of piano exercises and etudes.</p><p>Czestochowa \ 1 chen(t)-sto- , ko-v9\ City (pop., 2000 est.: 255,500),  south-central Poland, situated on the Warta River.

It originated in Zurich,  Switz., in 1916 and flourished in New York City, Paris, and the German  cities of Berlin, Cologne, and Hannover in the early 20th century. The  name, French for �hobbyhorse,� was selected by a chance procedure and  adopted by a group of artists, including Jean Arp, Marcel Duchamp, Man  Ray, and Francis Picabia, to symbolize their emphasis on the illogical and  absurd. The movement grew out of disgust with bourgeois values and  despair over World War I. The archetypal Dada forms of expression were  the nonsense poem and the ready-made. Dada had far-reaching effects on  the art of the 20th century; the creative techniques of accident and chance  were sustained in Surrealism, Abstract Expressionism, conceptual art, and Pop  art.</p><p>Daddi \'dad-de\, Bernardo (b. c. 1290, Florence?�d. c. 1355, Flo�  rence?)

In 1826  Nicephore Niepce learned of Daguerre�s experiments in obtaining perma�  nent pictures by the action of sunlight, and the two became partners in  the development of Niepce�s heliographic process until Niepce�s death in  1833. Continuing to experiment, Daguerre discovered that exposing an  iodized silver plate in a camera would create a lasting image if the latent  image on the plate was developed and fixed. In 1839 a description of his  daguerreotype process was announced at the Academy of Sciences.</p><p>daguerreotype \d3-'ge-ro-,tIp\ First successful form of photography.  It is named for Louis Daguerre, who invented the technique in collabora�  tion with Nicephore Niepce. They found that if a copper plate coated with  silver iodide was exposed to light in a camera, then fumed with mercury  vapour, and fixed (made permanent) by a solution of common salt, a per�  manent image would be formed. The first daguerreotype image was pro�  duced in 1837, by which time Niepce had died, so the process was named  for Daguerre. Many daguerreotypes, especially portraits, were made in  the mid 19th century; the technique was gradually replaced by the wet  collodion process, introduced in 1851.</p><p>Dahl \'dal\, Roald (b. Sept. 13, 1916, Llandaff, Wales�d. Nov. 23,  1990, Oxford, Eng.) British writer. A fighter pilot during World War II,  he began his writing career when C.S. Forester encouraged him to write  about his combat adventures; they were published by The Saturday  Evening Post. The short-story collection Someone Like You (1953) was a  best-seller; his later stories, many published in The New Yorker, often  include bizarre or supernatural elements. His popular children�s books  James and the Giant Peach (1961) and Charlie and the Chocolate Fac�  tory (1964) were made into films.</p><p>dahlia \'dal-ya\ Any of the 12-20 species of tuberous-rooted herbaceous  plants that make up the genus Dahlia, in the composite family, native to  higher elevations of Mexico and Central America. The leaves of most are  segmented and toothed or cut. About six species have been bred for cul�  tivation as ornamental flowers. Wild species have both disk and ray flow�  ers in the flowering heads, but many varieties of ornamentals, such as the  common garden dahlia ( D. bipinnata), have shortened ray flowers. Dahlia  flowers may be white, yellow, red, or purple.</p><p>Dahmer, Jeffrey (b. May 21, 1960, Milwaukee, Wis., U.S.�d. Nov.  28, 1994, Portage, Wis.) U.S. serial killer. In 1992 he confessed to kill�  ing, dismembering, and, in some cases, cannibalizing 16 young men,  chiefly near his Milwaukee home, in a killing spree that started in 1978,  when he murdered a young hitchhiker. The grim details, including his  freezer packed with human body parts, made global news. His insanity  plea was rejected by a jury, and he was sentenced to 15 consecutive life  terms in 1992 (a 16th was later added for the 16th murder). He was mur�  dered by a fellow inmate in 1994.</p><p>Dahomey See Benin</p><p>Dahomey kingdom Western African kingdom that flourished in the  18th�19th century in what is now central Benin. Initially called Abomey,  its name was changed to Dahomey after it had expanded by conquering  the neighbouring kingdoms of Allada (1724) and Whydah (1727). It  thrived on the slave trade with Europe, reaching its high point under Gezu  (1818-58), under whom it became independent of the Oyo empire. Soci�  ety was rigidly stratified into royalty, commoners, and slaves; a central�  ized bureaucracy carried out the king�s will. The nation was organized for  war, both to increase its territory and to take captives for the slave mar�  ket, and women served as soldiers along with men. With the end of the  slave trade in the 1840s, Dahomey began exporting palm oil, which  proved less profitable, and an economic decline followed. In 1892 Daho�  mey was defeated by a French expedition and became part of the French  colony of the same name.</p><p>Dahshur \da-'shur\ Ancient pyramid site, northern Egypt.

He patented one of the first successful internal-combustion  engines in 1885 and was the first to use a gasoline engine to power a  bicycle (see motorcycle). Further innovations culminated in 1889 in a  commercially feasible four-wheeled automobile. In 1890 the Daimler  company was founded at Cannstadt, and in 1899 it produced the first  Mercedes car. In 1926 it merged with the company founded by Karl Benz.  See also Daimler-Chrysler AG.</p><p>DaimlerChrysler AG German automotive manufacturer.

The Mercedes-Benz  luxury car, first produced by Daimler in 1901, is the basis of the compa�  ny�s financial success. DaimlerChrysler makes passenger cars, trucks, and  commercial vehicles such as buses. Its brands include Mercedes, Dodge,  Jeep, and Plymouth.</p><p>daimyo \'di-me-,o\ Any of the largest and most powerful landholding  magnates in Japan (c. 10th�19th century). The term was originally applied  to military lords who gained territorial control over the various private  estates into which the country had been divided; later, in the 14th-15th  centuries, daimyo acted as military governors for the Ashikaga shogunate  (see Muromachi period). Though they held legal jurisdiction over areas as  large as provinces, their private landholdings were relatively small. As  the country descended into internecine war, daimyo tended to hold small  but consolidated domains in which all the land belonged to themselves  or their vassals. Gradually, through constant battles, fewer and fewer  daimyo came to hold increasing amounts of territory. When Tokugawa  Ieyasu completed unification of Japan in 1603, roughly 200 daimyo had  been brought under Tokugawa hegemony. During the Tokugawa period  (1603-1867), the daimyo acted as local rulers in three-fourths of the  country. After the Meiji Restoration, the daimyo were converted into a  pensioned nobility residing in Tokyo.

Though cattle, goats, and sheep  have been kept for the production of dairy products since the earliest his�  torical times, modern dairy farming resulted from the technological  advances of the past hundred years: the factory system for processing;  sterile storage; refrigeration, fast vehicles and paved roads; and pasteur�  ization and the enforcement of food-safety laws. Outstanding dairy breeds  include the Holstein, Guernsey, Jersey, Ayrshire, and Brown Swiss.</p><p>daisy Any of several species of garden plants in the composite family,  especially the oxeye daisy (Chrysanthemum leucanthemum) and the  English, or true, daisy {Beilis perennis). Both are native to Europe but  have become naturalized in the U.S. These and other plants called dai�  sies are distinguished by a flower composed of 15-30 white ray flowers  surrounding a bright yellow disk flower. The cultivated Shasta daisy (C.  maximum) resembles the oxeye daisy but has larger flower heads. The  English daisy is often used as a bedding plant.</p><p>Dakar \da-'kar, 'da-,kar\ City (pop., 1999 est.: urban agglomeration,  1,999,000), capital of Senegal. One of the chief seaports on the western  African coast, it lies midway between the mouths of the Gambia and Sene�  gal rivers. Founded by the French in 1857, its development was spurred  by the opening in 1885 of western Africa�s first railway, from Saint-Louis  to Dakar. In 1902 it became the capital of French West Africa and, in 1960,  of Senegal. Dakar is one of tropical Africa�s leading industrial and ser�  vice centres.

As premier (1938�40), he sought to avoid war by signing the  Munich agreement. Arrested after France fell to Germany in World War II,  he was imprisoned by the Germans until 1945. After the war he returned  to the Chamber of Deputies (1946-58).</p><p>Dalai Lama V.da-lI-'la-moX Head of the dominant Dge-lugs-pa order of  Tibetan Buddhism. The first of the line was Dge-�dun-grub-pa (1391-1475),  founder of a monastery in central Tibet. His successors were regarded as  his reincarnations and, like himself, manifestations of the bodhisattva  Avalokitesvara. The second head of the order established the �Brasspungs  monastery near Lhasa as its base, and the third received the title Dalai  (�Ocean�) from Altan Khan. The fifth, Ngag-dbang-rgya-mtsho (1617�  1682), established the supremacy of the Dge-lugs-pa over other orders.  The 13th Dalai Lama, Thub-bstan-rgya-mtsho (1875-1933), held tempo�  ral and spiritual power after the Chinese were expelled in 1912. The 14th  and current Dalai Lama, Bstan-�dzin-rgya-mtsho (b. 1935), was enthroned  in 1940 but fled in 1959 with 100,000 followers after a failed revolt  against the Chinese, who had gained control of Tibet in 1950-51. His  government-in-exile is in Dharmsala, India.

A  lawyer in his native Chicago, Daley served as state director of revenue  (1948-50) and clerk of Cook county (1950-55) before being elected  mayor. He pushed urban renewal and highway construction and a sweep�  ing reform of the police department, but he was criticized for failing to  eliminate racial segregation in housing and public schools, for promoting  downtown skyscraper construction, and for police brutality committed  against demonstrators at the 1968 Democratic National Convention. His  tight control of city politics through job patronage won him a reputation  as �the last of the big-city bosses.� His last years were marred by scan�  dals surrounding members of his administration.

He entered Parliament in 1837 and later served as president of the  Board of Trade, gaining a reputation for administrative efficiency. As  governor-general of India he acquired territory by both peaceful and mili�  tary means. Though he created the map of modem India through his  annexations of independent provinces, his greatest achievement was the  molding of these provinces into a modern centralized state. He developed</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Dalhousie University &#x25BA; Dalton I 507</p><p>a modern communication and trans�  portation system and instituted social  reforms.

He studied in Madrid and Barcelona before  moving to Paris, where, in the late 1920s, after reading Sigmund Freud�s  writings on the erotic significance of subconscious imagery, he joined the  Surrealist group of artists. Once Dali hit on this method, his painting style  matured with extraordinary rapidity, and from 1929 to 1937 he produced  the paintings that made him the world�s best-known Surrealist artist. His  paintings depict a dream world in which commonplace objects, painted  with meticulous realism, are juxtaposed, deformed, or metamorphosed in  bizarre ways. In his most famous painting, The Persistence of Memory  (1931), limp watches melt in an eerie landscape. With Luis Bunuel he made  the Surrealist films Un Chien andalou (1928) and L�Age d�or (1930).  Expelled from the Surrealist movement when he adopted a more academic  style, he later designed stage sets, jewelry, interiors, and book illustra�  tions. His highly accessible art�and the publicity attracted by the eccen�  tricity, exhibitionism, and flamboyant behaviour he cultivated throughout  his life�made him extremely wealthy.</p><p>"Dali Atomicus," or Dali with everything in suspension, photograph by Philippe  Halsman, 1948</p><p>� PHIUPPE HALSMAN</p><p>Dalian Vda-'lyen\ or Ta-lien formerly (1950-81) Luda Ylte-'daV or  Lu-ta Japanese and conventional Dairen \'dl-'ren\ City (pop., 2003 est.:  2,181,600) and deepwater port on the Liaodong Peninsula, Liaoning prov�  ince, China.

While cotton fed the  town�s growth, the discovery in 1930 of the great East Texas oil field made  the city a major centre of the petroleum industry. It saw spectacular growth  after World War II, when several large aircraft-manufacturing firms  located in the area. These were followed by electronics and automobile-  assembly plants. It is the headquarters of many insurance companies and  the Southwest�s leading financial centre, as well as a transportation hub.  Its many educational institutions include Southern Methodist University  (founded 1911). It is known for its cultural activities including opera, bal�  let, and symphony concerts.

It is navigable for 70 mi (115  km) above its tidal mouth.</p><p>dam Barrier built across a stream, river, or estuary to conserve water for  such uses as human consumption, irrigation, flood control, and electric-  power generation. The earliest recorded dam is believed to be a masonry  structure 49 ft (15 m) high built across the Nile River in Egypt c. 2900  bc. Modem dams are generally built of earth fill, rock fill, masonry, or  monolithic concrete. Earth-fill (or embankment) dams, such as Egypt�s  Aswan High Dam, are usually used across broad rivers to retain water. The  profile of an earth-fill dam is a broad-based triangle. Concrete dams may  take various forms. The gravity dam uses its own dead weight to resist  the horizontal force of the water. Concrete-buttress dams reduce material  in the wall itself by using support buttresses around the outside base. An  arch dam, such as Hoover Dam, is built in a convex arch facing the res�  ervoir, and owes its strength essentially to its shape, which is particularly  efficient in transferring hydraulic forces to supports.</p><p>damages In law, the money awarded to a party in a civil suit as repa�  ration for the loss or injury for which another is liable. The theory of an  award of damages in a personal-injury or other tort case is that injured  parties should be placed in the position they would have been in if the  injury had not occurred, so far as this can be accomplished with a mon�  etary award. Where the legal wrong at issue is the breach of a contract,  the goal of the damages remedy is to give the injured parties the benefit  they would have received had the contract been performed.

Believed to be the world�s oldest continuously inhabited city,  it has evidence of occupation from the 4th millennium bc. The first writ�  ten reference to it is found in Egyptian tablets of the 15th century bc, and  biblical sources refer to it as the capital of the Aramaeans. It changed  hands repeatedly over the centuries, belonging to Assyria in the 8th cen�  tury bc, then Babylon, Persia, Greece, and Rome. It remained under the  control of Rome and its successor state, the Byzantine Empire, until it fell  to the Arabs in ad 635. Damascus flourished as the capital of the Umayyad  dynasty, and the remains of their Great Mosque still stand. Taken by the  Ottoman Empire in 1516, it remained under Ottoman rule until 1918; it  was occupied by France in 1920 and became part of independent Syria  in 1946. Today the city is a flourishing trading centre, with many educa�  tional and scientific institutions.

Unless a child keeps pumping a swing, the back-and-forth motion  decreases; damping by the air�s friction opposes the motion and removes  energy from the system. Viscous damping is caused by such energy losses  as occur in liquid lubrication between moving parts or in a liquid forced  through a small opening by a piston, as in automobile shock absorbers.  Hysteresis damping involves energy loss within the moving structure  itself. Other types of damping include electrical resistance, radiation, and  magnetic damping.</p><p>Dana, Charles A(nderson) (b.

Dana lived at  the utopian Brook Farm community for five years in the 1840s before  becoming an editor for Horace Greeley�s New York Tribune, where he  actively promoted the antislavery cause. He became a national figure as  editor and part owner of the New York Sun (1868-97), which under his  control was much admired and imitated. With George Ripley, he edited  the New American Cyclopaedia (1857-63). He also edited a highly suc�  cessful verse anthology and wrote books such as The Art of Newspaper  Making (1895).</p><p>Dana, James D(wight) (b. Feb. 12,1813, Utica, N.Y., U.S.�d.

He joined a U.S. exploring  expedition to the South Seas (1838-42), acting as a geologist and zoologist.  His contributions to the American Journal of Science stimulated U.S. geo�  logic inquiry. His research into the formation of the Earth�s continents and  oceans led him to believe in the progressive evolution of the Earth�s physi�  cal features over time. By the end of his life he also came to accept the  evolution of living things, as articulated by Charles Darwin.

Dana left  Harvard College because of weakened eyesight and shipped out as a  common sailor; after regaining his health, he returned and became a law�  yer. He is remembered for his autobiographical Two Years Before the Mast  (1840), which revealed the abuses endured by sailors. The Seaman�s  Friend (1841) became the authoritative guide to seamen�s legal rights and  duties.

Mother and  child were then placed in a wooden  box and cast into the sea, and they  drifted ashore on the island of Seri-  phus. Perseus grew up there, and  when the island�s king, Polydectes,  desired Danae, he sent the young  hero off in pursuit of the Medusa.</p><p>Perseus later rescued his mother and took her to Argos.</p><p>dance Form of expression that uses bodily movements that are rhyth�  mic, patterned (or sometimes improvised), and usually accompanied by  music. One of the oldest art forms, dance is found in every culture and is  performed for purposes ranging from the ceremonial, liturgical, and magi�  cal to the theatrical, social, and simply aesthetic. In Europe, tribal dances  often evolved into folk dances, which became stylized in the social dances  of the 16th-century European courts. Ballet developed from the court  dances and became refined by innovations in choreography and technique.  In the 20th century, modern dance introduced a new mode of expressive  movement.

After a career as a  Venetian diplomat, he was elected doge at age 85. He swore the �ducal  promise,� spelling out the duties of his office, and instituted reforms,  revising the penal code and publishing the first Venetian civil code. He  also revised the coinage and sought to promote trade with the East. In  1199 he fought a victorious war against the Pisans. He was prominent in  the Fourth Crusade, offering ships and supplies in return for payment (see  Treaty of Venice). When the Crusaders were unable to pay, they agreed to  help recover Zara for Venice and helped place Alexius IV on the Byzan�  tine throne, an action that led to the conquest of Constantinople. As a  leader of the expedition, Dandolo took the title �Lord of the Fourth Part  and a Half of the Empire of Romania,� which equaled the territory of the  Byzantine Empire given to the Venetians.</p><p>dandruff Skin disorder of the scalp, a mild form of dermatitis.

The first six chapters tell of Daniel and  his adventures in Babylon, including the stories of Daniel�s delivery from  the lion�s den, the Jews in the fiery furnace, and the writing on the wall  at Belshazzar�s feast. The rest of the book offers apocalyptic visions of the  end of history and the last judgment. Though it contains references to rul�  ers of the 6th century bc, the book is thought to have been written in the  2nd century bc during the persecutions of the Jews under Antiochus IV  Epiphanes. Daniel�s upright character made him a model for a persecuted  community.</p><p>Daniel Romanovich \r3-'man-3- I vich\ known as Daniel of Gali�  cia (b. 1201�d. 1264) Ruler of Galicia and Volhynia, one of the most  powerful princes in east central Europe. He inherited the two principali�  ties at age 4, but pretenders to the succession kept him from ruling. He  finally gained control over Volhynia in 1221 and Galicia in 1238. Daniel  enriched his realm, but Mongol invasions (1240-41) forced him to  acknowledge the rule of the khan. He led a rebellion against the Mongols  (1256) and succeeded briefly in driving them out of Volhynia, but another  Mongol force subdued the principality in 1260.</p><p>Daniels, Josephus (b.

His prodigious output includes The Child of Pleasure (1898), intro�  ducing the first of his many passionate Nietzschean-Superman heroes; The  Triumph of Death (1894), his best-known novel; Alcyone (1904), consid�  ered his greatest poetic work; and the powerful play The Daughter ofJorio  (1904). His works are marked by egocentrism, fluent and melodious style,  and an overriding emphasis on sensual gratification. He urged Italy�s entry  into World War I, in which he distinguished himself militarily. In 1919  he set himself up as dictator of the port city Fiume in defiance of the Treaty  of Versailles and effectively secured it for Italy; he was forced to step  down in 1920. He later became an ardent fascist.

Dante was of noble  ancestry, and his life was shaped by the conflict between papal and impe�  rial partisans (the Guelphs and Ghibellines). When an opposing political fac�  tion within the Guelphs (Dante�s party) gained ascendancy, he was exiled  (1302) from Florence, to which he never returned. His life was given  direction by his spiritual love for Beatrice Portinari (d. 1290), to whom he  dedicated most of his poetry. His great friendship with Guido Cavalcanti  shaped his later career as well. La Vita Nuova (1293?) celebrates Beatrice  in verse. In his difficult years of exile, he wrote the verse collection The  Banquet (c. 1304-07); De vulgari eloquentia (1304-07; �Concerning Ver�  nacular Eloquence�), the first theoretical discussion of the Italian literary</p><p>Alexandra Danilova in Swan Lake.</p><p>THE BE1TMANN ARCHIVE</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Danton &gt; D'Arcy I 511</p><p>language; and On Monarchy (1313?), a major Latin treatise on medieval  political philosophy. He is best known for the monumental epic poem The  Divine Comedy (written c. 1310-14; originally titled simply Commedia),  a profoundly Christian vision of human temporal and eternal destiny. It is  an allegory of universal human destiny in the form of a pilgrim�s journey  through hell and purgatory, guided by the Roman poet Virgil, then to Para�  dise, guided by Beatrice. By writing it in Italian rather than Latin, Dante  almost singlehandedly made Italian a literary language, and he stands as  one of the towering figures of European literature.</p><p>Danton \da nJ to n \, Georges (-Jacques) (b.

He was elected minister of justice in 1792, and  he became a member of the first Committee of Public Safety in April 1793.  Effectively the head of government for three months, he pursued a policy  of compromise and negotiation. He was not reelected to the Committee  when its term expired in Jitly, and he became leader of the moderate  Indulgents, which had risen from the Cordeliers.

In Confucianism, dao signifies a morally  correct path of behaviour. In Daoism the concept is more encompassing  and includes the visible process of nature, by which all things change, as  well as the principle underlying this process. This principle, known as</p><p>Absolute Dao, can be only imperfectly understood by the practitioner but  is the guiding principle in life.

Written between the 6th and 3rd centuries bc, it was once  called the Laozi after its traditional author Laozi, though its true author�  ship is still unresolved. The Daodejing presents a way of life intended to  restore harmony and tranquillity to a kingdom racked by disorder. It pro�  motes a course of nonaction, understood as restraint from any unnatural  action rather than complete passivity, thereby allowing the dao to resolve  things naturally. It was designed as a handbook for rulers, who should  rule by inaction, imposing no restrictions or prohibitions on their subjects.  The Daodejing has had a tremendous influence on all later schools of  Chinese philosophy and religion and has been the subject of hundreds of  commentaries.</p><p>Daoism or Taoism Vdau-.iz-omX Major Chinese religio-philosophical  tradition. Though the concept of dao was employed by all Chinese schools  of thought, Daoism arose out of the promotion of dao as the social ideal.  Laozi is traditionally regarded as the founder of Daoism and the author of  its classic text, the Daodejing . Other Daoist classics include the Zhuangzi  (4th-3rd century bc; ) and the Liezi. In Daoism, dao is the force or prin�  ciple about which nothing can be predicated, but that latently contains the  forms, entities, and forces of all phenomena. This natural wisdom should  not be interfered with; DE, or superior virtue, is acquired through action  so entirely in accordance with the natural order that its author leaves no  trace of himself in his work. The tradition holds that all beings and things  are fundamentally one. Daoism�s focus on nature and the natural order  complements the societal focus of Confucianism, and its synthesis with  Buddhism is the basis of Zen.

Strategically  important from antiquity, the Dardanelles was defended by Troy from its  position on the Asian side. In 480 bc the Persian Xerxes I crossed the strait  to invade Greece; Alexander the Great also crossed it in 334 bc on his  expedition against Persia.

In response to a Russian  appeal to relieve pressure against its troops on the Caucasus front, Brit�  ain agreed to a naval action against Turkey at the Dardanelles. When  bombardment alone failed, British and Australian and New Zealand  (ANZAC) troops landed on the Gallipoli peninsula in April 1915, where  they met strong resistance from Turkish forces under Mustafa Kemal  Ataturk. After six months of standoff, the campaign was halted and Allied  troops were skillfully withdrawn under difficult conditions. Allied casu�  alties numbered about 250,000.

A relief expedition that finally reached the colony in 1590  found only the word croatoan carved on a post; the infant Virginia had  vanished along with all the other colonists.</p><p>Darfur \dar-'fiir\ Historical region and former province, western Sudan.  It was an independent kingdom from c. 2500 bc. Its first traditional rul�  ers, the Daju, probably traded with ancient Egypt; they were succeeded  by the Tunjur. Darfur�s Christian period (c. 900-1200) was ended by the  advance of Islam with the empire of Kanem-Bornu. In the 1870s Darfur  came under Egyptian rule, and in 1916 it became a province of Sudan.</p><p>Darien \,dar-e-'en\ Traditional region, eastern Panama. Extending into  northwestern Colombia, it forms the link between Central America and  South America. A hot, humid area of tropical rainforests, it has always been  sparsely populated. The first European settlement in South America, Santa  Maria de la Antigua del Darien, was attempted there in 1510. From this  failing colony Vasco Nunez de Balboa made his famous march to the  Pacific Ocean in 1513.</p><p>Dario \da-'re-o\, Ruben pseudonym of Felix Ruben Garcia  Sarmiento (b. Jan. 18, 1867, Metapa, Nic.�d. Feb. 6, 1916, Leon)  Nicaraguan poet, journalist, and diplomat. At age 19 he began the travels  in Europe and the Americas that would continue throughout his life. The  diverse collection Azul (1888), written in an innovative simple, direct  style, is his first major work. As a diplomat in Buenos Aires (from 1893),  he became the centre of the new Modernismo movement. His Profane  Hymns (1896) was influenced by the French Symbolists. As a journalist  in Europe he became increasingly concerned with issues of imperialism  and nationalism. Songs of Life and Hope (1905) represents the culmina�  tion of his technical experimentation and artistic resourcefulness. In addi�  tion to his poetry, he wrote about 100 short stories.</p><p>Darius \da-'ri-9s\ I known as Darius the Great (b. 550�d. 486 bc)  King of Persia (522^1-86 bc). He was the son of Hystaspes, satrap of  Parthia. Much of what is known of him is through his own inscriptions.  He took the throne by force, killing Bardiya, a son of Cyrus the Great,  calling him an impostor who had usurped power. He continued the con�  quests of his predecessors, subduing Thrace, Macedonia, some Aegean  islands, and land stretching to the Indus valley. He failed in his great  expedition against the Scythians (513) but put down the Ionian revolt  (499), which had been supported by Eretria and Athens. After that he twice  tried to conquer Greece, but a storm destroyed his fleet in 492 and the  Athenians defeated him at the Battle of Marathon in 490. He died before  a third expedition could be launched. Among the greatest of the Achae-</p><p>menian dynasty, he was noted for his  administrative genius and his build�  ing projects, especially those at Per-  sepous.</p><p>Darjiling or Darjeeling City  (pop., 2001: 107,197), West Bengal  state, northeastern India.

Its economy is based prima�  rily on tea, which is plantation-  grown, and tourism.</p><p>dark matter Nonluminous matter  not directly detectable by astrono�  mers, hypothesized to exist because  the mass of the visible matter in the  universe cannot account for  observed gravitational effects. Long  believed to exist in large quantities,  it enters into many theories of the  origin of the universe and its present large-scale structure and into mod�  els of gravitation and other fundamental forces (see fundamental interac�  tion) between particles. Numerous candidates for dark matter have been  proposed over the years, but none has yet been confirmed.</p><p>Darlan \dar-'la n \, (Jean-Louis-Xavier-) Francois (b. Aug. 7,  1881, Nerac, France�d. Dec. 24, 1942, Algiers) French admiral. After  graduating from the French naval school (1902), he rose through the ranks  to become navy commander in chief (1939). After France�s defeat by  Germany in World War II, he entered Philippe Petain�s government as vice  premier and foreign minister (1941-42), then became commander in chief  of all Vichy France military forces. In 1942 he concluded an armistice with  the Allies in Algiers, then was killed by an anti-Vichy assassin.</p><p>Darling River River, southeastern Australia. It is the longest member  of the Murray-Darling river system. It rises in several headstreams in the  Great Dividing Range and flows generally southwest across New South  Wales for 1,702 mi (2,739 km) to join the Murray River at the Victoria  border.</p><p>Darlington, Cyril Dean (b. Dec. 19, 1903, Chorley, Lancashire,  Eng.�d. March 26, 1981) British biologist. A professor at the University  of Oxford from 1953, he believed that chromosomes were the cellular  components that passed hereditary information from generation to gen�  eration. He explained the behaviour of chromosomes during meiosis, for�  mulating a theory of evolution in which the exchange of parts of  chromosomes (crossing-over) was the central variable in determining the  inherited characteristics of the next generation. His Evolution of Man and  Society (1969) raised controversy by insisting that the intelligence of races  was determined by inheritance.</p><p>Darnley, Henry Stewart, Lord (b. Dec. 7, 1545, Temple Newsom,  Yorkshire, Eng.�d. Feb. 9/10, 1567, Edinburgh, Scot.) English noble�  man, second husband of Mary, Queen of Scots, and father of James I. Son  of Matthew Stewart, earl of Lennox (1516-71), a pretender to the Scot�  tish throne, Henry wed his cousin Mary in 1565 despite the opposition  of Elizabeth I and Scottish Protestants. It became evident, even to Mary,  that superficial charm was his only positive attribute. After he played a  role in the murder of Mary�s secretary, David Riccio, he was himself mur�  dered at age 21 at the instigation of James Hepburn, earl of Bothwell  (1535-78), whom Mary soon married.</p><p>Darrow Vdar-6\, Clarence (Seward) (b.

Darrow moved to Chicago in 1887 and immedi�  ately joined the effort to free anarchists charged with murder in the Hay-  market Riot. He was appointed Chicago city corporation counsel (1890)  and then became general attorney for the Chicago and North Western  Railway. His defense of Eugene V.

He represented striking Pennsylvania coal miners, draw�  ing attention to working conditions and the use of child labour (1902-03);  secured the acquittal of William Haywood in the assassination of Gov.  Frank R. Steunenberg of Idaho (1907); and sought to defend the  McNamara brothers, accused of bombing the Los Angeles Times building  (1911). He saved Richard Loeb and Nathan Leopold from a death sen�  tence for the murder of 14-year-old Robert Franks and won acquittal for  members of an African American family who had fought a mob trying to  expel them from their home in a white Detroit neighbourhood (1925-26).  Perhaps his most famous case was the Scopes trial (1925), in which he  defended a high school teacher who was charged with violating a Ten�  nessee state law against teaching Darwin�s theory of evolution.</p><p>darshan or darsan Vdor-shon, 'dar-shon\ In Hindu worship, the  beholding of an auspicious deity, person, or object. The experience is often  conceived to be reciprocal and results in a blessing of the viewer. In  rathayatras (car festivals), images are carried through the streets to allow  viewing by those who formerly would not have been allowed in the  temple. Darshan may also be imparted by a guru to his disciples, a ruler  to his subjects, or a pilgrimage shrine to its visitors. In Indian philosophy,  darshan also refers to a philosophical system (e.g., Vedanta).</p><p>Dart, Raymond Arthur (b. Feb. 4, 1893, Toowong, Brisbane,  Queen., Austl.�d. Nov. 22, 1988, Johannesburg, S.Af.) Australian-born  South African physical anthropologist and paleontologist. In 1925, when  Asia was still believed to be the cradle of humankind, Dart�s announce�  ment of the discovery of the Taung skull near the Kalahari substantiated  Charles Darwin�s prediction that such ancestral hominin forms would be  found in Africa. Dart named the skull, establishing it as the type speci�  men of a new genus and species, Australopithecus africanus. He lived to  see his findings corroborated by additional discoveries that firmly estab�  lished Africa as the site of human origins. Dart taught at the University  of the Witwatersrand from 1923 to 1958.</p><p>darter Any of about 100 species of small, slender freshwater fishes  (family Percidae), native to eastern North America. Darters live near the  bottom of clear streams, darting quickly about when disturbed or when  feeding on small aquatic animals such as insects and worms. They have  two dorsal fins and often are brightly coloured. Most species are 2-3 in.  (5-7 cm) long, but some grow to 9 in. (23 cm). Some species lay their  eggs and abandon them; the males of other species establish a nest and  guard the eggs until hatched. See also snail darter.</p><p>Dartmouth Vdart-mothX College Private institution of higher learning  in Hanover, N.H., a traditional member of the Ivy League. It is consistently  ranked as one of the best liberal arts colleges in the U.S. It was founded  in 1769 by Rev. Eleazar Wheelock (1711-79) for the education of �youth  of the Indian Tribes . . . English Youth and others.� The original charter  was approved by King George III. Women were first admitted in 1972.  Besides offering a broad range of undergraduate programs, Dartmouth  grants graduate and professional degrees in the arts and sciences, busi�  ness, engineering, and medicine. See also Dartmouth College case.</p><p>Dartmouth College case formally Trustees of Dartmouth Col�  lege v. Woodward Case in which the U.S. Supreme Court held  (1819) that the charter of Dartmouth College, granted in 1769 by King  George III, was a contract and as such could not be impaired by the New  Hampshire legislature. State legislators had tried to alter the contract�s  terms regarding the continuance of the board of trustees, an effort rejected  by the court. The decision was far-reaching in its application to business  charters, protecting businesses and corporations from much government  regulation. Dartmouth�s case was argued by Daniel Webster.</p><p>darts Indoor target game. It is played by throwing feathered darts at a  circular board with numbered spaces. The board, usually made of cork,  bristle, or elmwood, is divided into 20 sectors valued at points from 1 to  20. Six concentric rings, ranging from an inner bull�s-eye to a narrow  outermost ring, determine scoring. The official throwing distance in most  countries is 7 ft 9.25 in. (2.37 m), though variations extend up to 9 ft  (2.75 m). In Britain, darts is normally played in pubs.</p><p>Darwin formerly Palmerston Seaport (pop., 2001 prelim.: 69,698),  capital of Northern Territory, Australia. Located on Port Darwin, a deep  inlet of Clarence Strait in the Timor Sea, it has one of Australia�s best  harbours. The harbour was named in 1839 for Charles Darwin. The port,  settled in 1869, was known as Palmerston until 1911. Located in a largely  undeveloped region, Darwin is a supply and shipping centre for northern</p><p>Australia. A military base in World War II, it was bombed by the Japa�  nese in 1942, then extensively rebuilt. A cyclone in 1974 damaged or  destroyed nearly all of the city; rebuilt a second time, it is now one of  Australia�s most modem cities.</p><p>Darwin, Charles (Robert) (b. Feb. 12, 1809, Shrewsbury, Shrop�  shire, Eng.�d. April 19, 1882, Downe, Kent) British naturalist. The  grandson of Erasmus Darwin and Josiah Wedgwood, he studied medicine  at the University of Edinburgh and biology at Cambridge. He was rec�  ommended as a naturalist on HMS Beagle, which was bound on a long  scientific survey expedition to South America and the South Seas (1831-  36). His zoological and geological discoveries on the voyage resulted in  numerous important publications and formed the basis of his theories of  evolution. Seeing competition between individuals of a single species, he  recognized that within a local population the individual bird, for example,  with the sharper beak might have a better chance to survive and repro�  duce and that if such traits were passed on to new generations, they would  be predominant in future populations. He saw this natural selection as the  mechanism by which advantageous variations were passed on to later  generations and less advantageous traits gradually disappeared. He  worked on his theory for more than 20 years before publishing it in his  famous On the Origin of Species by Means of Natural Selection (1859).  The book was immediately in great demand, and Darwin�s intensely con�  troversial theory was accepted quickly in most scientific circles; most  opposition came from religious leaders. Though Darwin�s ideas were  modified by later developments in genetics and molecular biology, his  work remains central to modern evolutionary theory. His many other  important works included Variation in Animals and Plants Under Domes�  tication (1868) and The Descent of Man... (1871). He was buried in  Westminster Abbey. See also Darwinism.</p><p>Darwin, Erasmus (b. Dec. 12, 1731, Elston Hall, Nottinghamshire,  Eng.�d. April 18, 1802, Derby, Der�  byshire) British physician, grandfa�  ther of Charles Darwin and Francis  Galton. A freethinker and radical,</p><p>Darwin often wrote his opinions and  scientific treatises in verse. In  Zoonomia; or, The Laws of Organic  Life (1794-96), he advanced a theory  of evolution similar to that of La�  marck, suggesting that species modi�  fied themselves by adapting to their  environment in an intentional way.</p><p>His conclusions, drawn from simple  observation, were rejected by the  more sophisticated 19th-century sci�  entists, including his grandson  Charles.</p><p>Darwinism Theory of the evolu�  tionary mechanism proposed by  Charles Darwin as an explanation of  organic change. It denotes Darwin�s  specific view of how evolution  works. Darwin developed the con�  cept that evolution is brought about by the interplay of three principles:  variation (present in all forms of life), heredity (the force that transmits  similar organic form from one generation to another), and the struggle for  existence (which determines the variations that will be advantageous in a  given environment, thus altering the species through selective reproduc�  tion). Present knowledge of the genetic basis of inheritance has contrib�  uted to scientists� understanding of the mechanisms behind Darwin�s  ideas, in a theory known as neo-Darwinism.</p><p>Darwin's finch or Galapagos finch Any of 14 species (in three  genera) of songbirds (family Fringillidae) whose adaptations to several  ecological niches in the Galapagos Islands and Cocos Island gave Charles  Darwin evidence for his thesis that �species are not immutable.� All the  species are 4-8 in. (10-20 cm) long and brownish or black, but they dif�  fer greatly in the configuration of the bill, which is suited to each species�  particular feeding habit.</p><p>Dassault \da-'so\, Marcel orig.

His company produced Europe�s first supersonic plane, the Mystere,  and in 1956 began production of the Mirage warplane, which would be  acquired by countries worldwide.</p><p>data compression Process of reducing the amount of data needed for  storage or transmission of a given piece of information (text, graphics,  video, sound, etc.), typically by use of encoding techniques. Data com�  pression is characterized as either lossy or lossless depending on whether  some data is discarded or not, respectively. Lossless compression scans  the data for repetitive sequences or regions and replaces them with a single  �token.� For example, every occurrence of the word the or region with  the colour red might be converted to $. ZIP and GIF are the most com�  mon lossless formats for text and graphics, respectively. Lossy compres�  sion is frequently used for photographs, video, and sound files where the  loss of some detail is generally unnoticeable. JPEG and MPEG (see MP3)  are the most common lossy formats.</p><p>data encryption Process of disguising information as �ciphertext,� or  data that will be unintelligible to an unauthorized person. Decryption is  the process of converting ciphertext back into its original format, some�  times called plaintext (see cryptography). Computers encrypt data by  applying an algorithm to a block of data. A personal key known only to  the message�s transmitter and intended receiver is used to control the  encryption. Well-designed keys are almost impregnable. A key 16 char�  acters long selected at random from 256 ASCII characters could take far  longer than the 15-billion-year age of the universe to decode, assuming  the perpetrator attempted 100 million different key combinations per sec�  ond. Symmetric encryption requires the same key for both encryption and  decryption. Asymmetric encryption, or public-key cryptography, requires  a pair of keys, one for encryption and one for decryption.</p><p>data mining Type of database analysis that attempts to discover use�  ful patterns or relationships in a group of data. The analysis uses advanced  statistical methods, such as cluster analysis, and sometimes employs arti�  ficial intelugence or neural network techniques. A major goal of data min�  ing is to discover previously unknown relationships among the data,  especially when the data come from different databases. Businesses can  use these new relationships to develop new advertising campaigns or  make predictions about how well a product will sell. Governments also  use these techniques to discern illegal or embargoed activities by indi�  viduals, associations, and other governments.</p><p>data processing Manipulation of data by a computer. It includes the  conversion of raw data to machine-readable form, flow of data through  the CPU and memory to output devices, and formatting or transformation  of output. Any use of computers to perform defined operations on data  can be included under data processing. In the commercial world, data  processing refers to the processing of data required to run organizations  and businesses.</p><p>data structure Way in which data are stored for efficient search and  retrieval. The simplest data structure is the one-dimensional (linear) array,  in which stored elements are numbered with consecutive integers and  contents are accessed by these numbers. Data items stored nonconsecu-  tively in memory may be linked by pointers (memory addresses stored  with items to indicate where the �next� item or items in the structure are  located). Many algorithms have been developed for sorting data efficiently;  these apply to structures residing in main memory and also to structures  that constitute information systems and databases.</p><p>data transmission Sending and receiving data via cables (e.g., tele�  phone lines or fibre optics) or wireless relay systems. Because ordinary  telephone circuits pass signals that fall within the frequency range of voice  communication (about 300-3,500 hertz), the high frequencies associated  with data transmission suffer a loss of amplitude and transmission speed.  Data signals must therefore be translated into a format compatible with  the signals used in telephone lines. Digital computers use a modem to  transform outgoing digital electronic data; a similar system at the receiv�  ing end translates the incoming signal back to the original electronic data.  Specialized data-transmission links carry signals at frequencies higher  than those used by the public telephone network. See also broadband tech�  nology; cable modem; DSL; ISDN; fax; radio; teletype; T1 ; wireless commu�  nications.</p><p>database Collection of data or information organized for rapid search  and retrieval, especially by a computer. Databases are structured to facili�  tate storage, retrieval, modification, and deletion of data in conjunction  with various data-processing operations. A database consists of a file or  set of files that can be broken down into records, each of which consists  of one or more fields. Fields are the basic units of data storage. Users  retrieve database information primarily through queries. Using keywords  and sorting commands, users can rapidly search, rearrange, group, and  select the field in many records to retrieve or create reports on particular  aggregates of data according to the rules of the database management sys�  tem being used.</p><p>database, relational See relational database</p><p>database management system (DBMS) System for quick search  and retrieval of information from a database. The DBMS determines how  data are stored and retrieved. It must address problems such as security,  accuracy, consistency among different records, response time, and memory  requirements. These issues are most significant for database systems on  computer networks. Ever-higher processing speeds are required for effi�  cient database management. Relational DBMSs, in which data are orga�  nized into a series of tables (�relations�) that are easily reorganized for  accessing data in different ways, are the most widely used today.</p><p>Date Line See International Date Line</p><p>date palm Tree (Phoenix dactylifera) of the palm family, found in the  Canary Islands and northern Africa, the Middle East, Pakistan, India, and  California. The trunk, strongly marked with the pruned stubs of old leaf  bases, ends in a crown of long, graceful, shining, pinnate leaves. The fruit,  called the date, is a usually oblong brown berry. Dates have long been an  important food in desert regions, and are the source of syrup, alcohol, vin�  egar, and a strong liquor. All parts of the tree yield products of economic  value, being used variously for timber, furniture, basketry, fuel, rope, and  packing material. The seeds are sometimes used as stock feed. The tree is  grown as an ornamental along the Mediterranean shores of Europe. Its  leaves are used for the celebration of Palm Sunday (among Christians) and  the Feast of Tabernacles (among Jews). Date sugar, a product of India, is  obtained from the sap of a closely related species, P. sylvestris.</p><p>dating In geology and archaeology, the process of determining an  object�s or event�s place within a chronological scheme. Scientists may  use either relative dating, in which items are sequenced on the basis of  stratigraphic clues (see stratigraphy) or a presumed evolution in form or  structure, or absolute dating, in which items are assigned a date indepen�  dent of context. The latter type includes potassium-argon and carbon- 14  dating; both are based on the measurement of radioactive decay. The  record of changes in polarity of the Earth�s magnetic field has provided  a timescale for seafloor spreading and long-term marine sedimentation. Den�  drochronology has proved useful in archaeology and climatology.

He was trained by his father, also a painter. He began by paint�  ing historical and religious works but soon turned to landscapes, painting  rivers, beaches, and canals from a boat. His images were notable for their  uncrowded composition and accurate depiction of natural light. One of  the earliest proponents of painting directly from nature, he is considered  the link between mid-19th-century naturalism and Impressionism.</p><p>Daudet \do-'de\, Alphonse (b. May 13, 1840, Nimes, France�d.  Dec. 16, 1897, Paris) French short-story writer and novelist. Daudet wrote  his first novel at age 14. Unable to finish his schooling after his parents  lost all their money, he took a position in a duke�s household. He later  joined the army but fled the terrors of the Paris Commune of 1871. His  health was long undermined by poverty and by the venereal disease that  eventually cost him his life. He is remembered for his humorous, senti�  mental portrayals of the life and characters of southern France, inspired  by his experiences at several social levels. His many works include the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Daughters of the American Revolution &#x25BA; David I 515</p><p>story collection Monday Tales (1873), the play L�Arlesienne (1872), the  novels The Nabob (1877) and Sappho (1884), and several volumes of  memoirs. His son, Leon Daudet (1867-1942), edited with Charles Mau-  rras the reactionary review L�Action Frangaise and was a virulent sati�  rist and polemicist on the subjects of medicine and psychology as well  as public affairs.</p><p>Daughters of the American Revolution (DAR) U.S. patriotic  society for direct descendants of soldiers or others who aided the cause of  independence. It was organized in 1890 and chartered by Congress in 1895.  Its historical division stresses the study of U.S. history and preservation of  Americana. Its educational division provides scholarships and loans, helps  support schools for underprivileged youth and for Americanization train�  ing, sponsors prizes, and publishes manuals. Its patriotic division publishes  the Daughters of the American Revolution Magazine and The National  Defense News. It was long known for its conservatism; its refusal in 1939  to let the black singer Marian Anderson perform at Washington�s Consti�  tution Hall led to her famous concert at the Lincoln Memorial.</p><p>Daumier \dom-'ya\, Honore (-Victorin) (b. Feb. 20/26, 1808,  Marseille, Fr.�d. Feb. 11, 1879, Valmondois) French painter, sculptor,  and caricaturist. He was bom into a family of artists. From age 13 he  worked for a bailiff in a law court and later as a clerk in a bookstore,  where he observed and analyzed the appearance and behaviour of people  of different social classes. In 1829, after studying lithography, he began  contributing cartoons and drawings satirizing 19th-century French poli�  tics and society to periodicals and came to enjoy a wide reputation. He  produced more than 4,000 lithographs and 4,000 illustrative drawings. His  paintings, drawing upon literary themes and documenting contemporary  life and manners, were executed in a vigorous, sketchy style; they were  rarely exhibited, and he remained unknown as a painter. In sculpture he  specialized in caricature heads and figures; some 15 small clay busts  occupy an important place in the history of sculpture.</p><p>dauphin Vdo-fonV Title of the eldest son of a king of France, the heir  apparent to the French crown, from 1350 to 1830. Derived from a per�  sonal name, dauphin was originally used as a title in the 12th century by  French counts in Auvergne and Vienne. The title came to the French crown  through the purchase of lands known as the Dauphine in 1349 by Philip  VI, who bestowed it on his grandson, the future Charles V. Dauphin came  to designate the heir apparent during the reign of Charles V, who gave his  son, Charles VI, the title and the Dauphine.</p><p>Dauphine \,do-fe-'na\ Historic region and former province, southeast�  ern France. Occupied by Burgundians and later by Franks, it formed part  of the Middle Kingdom of Lothar I after the division of the Carolingian  empire in 843 and was part of the kingdom of Arles. It was sold to Philip  VI of France and ultimately became an appanage of the eldest son of the  French king, who assumed the title (dauphin) attached to the land. The  area had a quasi-independent status until it was annexed to France in 1457.  Dauphine encompasses portions of the modern administrative regions of  Rhone-Alpes and Province-Alpes-Cote d�Azur.</p><p>Davao \'da-,vau\ City (pop., 2000: metro, area, 1,147,116), southeast�  ern Mindanao Island, Philippines.

Razed dur�  ing World War II, the rebuilt city is a blend of Spanish, American, and  Moorish influences. Largely rural outside its urban core, it is one of the  world�s largest cities in area, covering 854 sq mi (2,212 sq km). It is the  site of the University of Mindanao (1946).</p><p>Davenant Vdav-o-nontX, Sir William or William D'Avenant (b.</p><p>1606, Oxford, Eng.�d. April 7, 1668, London) British poet, playwright,  and theatre manager. Early works include the comedy The Witts (licensed  1634) and a volume of poems, Madagascar (1638). He was made poet  laureate in 1638. Involved in intrigues during the English Civil Wars, he  was imprisoned at the Tower of London, where he worked on his verse  epic Gondibert (1651). Later he made the first attempt to revive English  drama (banned under Oliver Cromwell) and brought the first opera, painted  stage sets, and female actress-singer to the English public stage. After the  Restoration he continued playwriting and founded a playhouse.</p><p>Davenport, John (b. April 1597, Coventry, Warwickshire, Eng.�d.  c. March 15, 1670, Boston, Mass.) British-American Puritan clergyman.  A vicar in London, he moved to Amsterdam in 1633 and served there as  co-pastor of the English Church. In 1637 he left for America with Theo-</p><p>philus Eaton (c. 1590-1658) and their followers. They founded a colony  at Quinnipiac (New Haven) in 1638; Davenport became pastor of the New  Haven church, and Eaton was chosen governor. After failing to prevent  New Haven�s union with the Connecticut colony, Davenport left in 1667  to lead the First Church in Boston.</p><p>David (b. Bethlehem, Judah�d. c. 962 bc, Jerusalem) Second of the  Israelite kings (r. c. 1000-c. 962 bc). David was an aide at the court of  Saul until the monarch�s jealousy forced him into outlawry. He became  king of Israel on Saul�s death. He captured Jerusalem from the Jebusites  and made it his capital, defeated the Philistines, and gained control of many  bordering kingdoms. He faced several revolts, including one by his third  son, Absalom. He unified all Israel into one kingdom and made Jerusalem  both the religious and political centre. He made the name Yahweh the  supreme name for the god of Israel, who was worshiped in Jerusalem,  and ruled that all other names for God were mere titles or attributes of  Yahweh. Though the kingdom split under David�s son and successor  Solomon, religious unity endured, and the house of David symbolized the  bond between God and Israel. The word MESSIAH comes from hameshiach,  the title of kings of the line of David.</p><p>David I (b. c. 1082 �d. May 24, 1153, Carlisle, Cumberland, Eng.) King  of the Scots (1124-53). The youngest of six sons of Malcolm III Canmore,  he became king of Scotland on the death of his brother Alexander I. He  created a rudimentary central administration, issued the first Scottish royal  coinage, and admitted into Scotland an influential Norman aristocracy.  David also reorganized Scottish Christianity to conform with European  and English usages and founded many religious communities. He had  obtained lands in central England through his marriage to the daughter of  an English earl in 1113, and he won title to Northumberland from the  future Henry II in 1149.</p><p>David II known as David the Builder (b. 1073�d. 1125) King of  Georgia (1089-1125). Sometimes known as David III, he became coruler  with his father, Giorgi II, in 1089. David defeated the Turks in the Battle  of Didgori (1122) and captured Tbilisi. Under his leadership Georgia  became the strongest state in Caucasia.</p><p>David II (b. March 5, 1324, Dunfermline, Fife, Scot.�d. Feb. 22, 1372,  Scotland) King of the Scots from 1329. In keeping with an Anglo-Scottish  peace treaty, he was married at age four to the sister of Edward III of  England. His reign was marked by conflict with England and a decline in  the prestige of the monarchy. He went into exile in France in 1334 after  Edward III supported a rival for the throne, and he fought against Edward  for the French king Philip VI. David returned to Scotland in 1341 and carried  out raids against the English, who captured him in 1346. He was released  in 1357 on the promise of ransom, and his offer to trade the Scottish throne  for forgiveness of the ransom money was repudiated in Scotland.</p><p>David Vda-v3t\, Gerard (b. c. 1460, Oudewater, Neth.�d.

Most  of his works are altarpieces and other panels featuring traditional religious  themes, but his best-known paintings, The Judgment of Cambyses and The  Flaying of Sisamnes (1498), deal with the theme of justice; they origi�  nally hung in the town hall of Bruges. His works are among the earliest  Flemish paintings to feature the Italian Renaissance iconography of putti  (male child angels) and garlands.</p><p>David \da-'ved\, Jacques-Louis (b. Aug. 30, 1748, Paris, France�d.  Dec. 29, 1825, Brussels) French  painter. At 18 he entered the Royal  Academy of Painting and Sculpture.</p><p>In 1775 he went to Rome and  became a proponent of the Neoclas�  sical style, but also studied the work  of such 17th-century painters as  Nicolas Poussin and Caravaggio. His  work came to epitomize the late  18th-century Neoclassical reaction  against the ornate Rococo style.</p><p>Among his subjects were classical,  historical, and mythological themes;  he was also a great portraitist. He  became the unchallenged painter of  the French Revolution, and later was  appointed official portraitist to Napo�  leon. He was also a founding mem�  ber of the new Institut de France,  which replaced the Royal Academy,  and produced commemorative med�  als and other revolutionary propa�  ganda. Among his masterpieces is The Death of Marat (1793), an  expression of universal tragedy as well as a portrayal of a key event of  the French Revolution. His influence on European art was pervasive; his  pupils included Antoine-Jean Gros and J.-A.-D. Ingres.</p><p>David, Star of Hebrew Magen David (�Shield of David�). Jewish  symbol composed of two overlaid equilateral triangles that form a six-  pointed star. It appears on synagogues, tombstones, and the flag of Israel.  An ancient sign not much used by Jews before the Middle Ages, it was  popularized by Kabbalists for protection against evil spirits. The Jewish  community of Prague adopted it as an official symbol and its use became  widespread in the 17th century. Though it has neither biblical nor Talmu�  dic authority, it became a nearly universal emblem of Judaism in the 19th  century. The Nazis� use of it to identify Jews invested it with the sym�  bolism of martyrdom and heroism.</p><p>David ap Llywelyn Vda-vith-ap-hb-'we-linX (b. c. 1208 �d. Feb. 25,  1246, Aber, Gynedd, Wales) Welsh prince, ruler of the state of Gwynedd  in northern Wales (1240-46). His father, Llywelyn ap Iorwerth, had made  Gwynedd the centre of Welsh power. David, the rightful heir, fought his  half brother for power and imprisoned him in 1239. He was forced to  cede part of his territory to Henry III of England (1241) and later went to  war against Henry. The first Welsh ruler to declare himself prince of  Wales, he fell ill and died while the war was in progress.</p><p>David of Tao \'tau\ (d. 1000) Georgian prince of the Bagratid family  of Tao, a region between Georgia and Armenia. A just ruler and a friend  of the church, he allied with Basil II to defeat the rebel Bardas Skleros  (976-979) and was rewarded with extensive lands that made him the most  important ruler in Caucasia. In 987-989 he supported Bardas Phokas  against Basil but was defeated and agreed to cede his lands to Basil on  his death. Despite this setback, David�s heir, Bagrat III (978-1014), was  able to become the first ruler of a unified Georgian kingdom.</p><p>Davidson, Bruce (b. Sept. 5, 1933, Oak Park, Ill., U.S.) U.S. photog�  rapher and filmmaker. After studying at the Yale University School of  Design he worked briefly at Life magazine and in 1958 joined the pho�  tographers� cooperative Magnum Photos. He produced numerous out�  standing photo-essays, the most important being East 100th Street (1970),  123 photographs shot with a large-format camera in East Harlem, New  York. He also made several short films.</p><p>Davidson, Donald (b. March 6, 1917, Springfield, Mass., U.S.�d.  Aug. 30, 2003, Berkeley, Calif.) U.S. philosopher. He taught at various  universities before settling at the University of California at Berkeley in  1981. In a series of seminal papers, he developed strikingly original and</p><p>unusually systematic positions on a wide range of traditional philosophi�  cal problems. According to his doctrine of anomalist monism, although  mental events are identical to physical events (in the brain) under appro�  priate descriptions, there are no psychophysical laws (in the strict sense)  that relate the two; it follows that reduction of the mental to the physical  is impossible (see also supervenience). He argued that a formal require�  ment for any adequate theory of linguistic meaning is that it generate theo�  rems that express the truth conditions of sentences in the �object  language� in terms of sentences in a metalanguage. He also developed  sophisticated arguments against the possibility of conceptual relativism (the  view that there are mutually unintelligible �conceptual schemes�) and  global skepticism (the view that most if not all of one�s beliefs about the  world may be false).</p><p>Davidson College Private liberal arts college in Davidson, North  Carolina, U.S., founded in 1837. It is affiliated with the Presbyterian  church, though its approach to learning is nonsectarian. Women were first  admitted in 1972.</p><p>Davies, Sir Peter Maxwell (b. Sept. 8, 1934, Manchester, Eng.)  British composer. He studied in England, Italy, and the U.S. He cofounded  the contemporary ensemble The Fires of London and was its musical  director (1970-87); he wrote many of his works for the group. Since 1970  he has lived and composed primarily in the remote Orkney Islands. He  has written many musical theatre works and has conducted orchestras  worldwide. His most famous compositions are Eight Songs for a Mad  King (1969) and An Orkney Wedding, with Sunrise ; his other works  include Vesalii leones (1969), Miss Donnithorne�s Maggot (1974), and  Ave maris Stella (1975); the operas Taverner (1968), The Martyrdom of  St. Magnus (1976), and Le Jongleur de Notre Dame (1978); and seven  symphonies.</p><p>Davies, (William) Robertson (b. Aug. 28, 1913, Thamesville, Ont.,  Can.�d. Dec. 2, 1995, Orangeville, Ont.) Canadian novelist and play�  wright. Educated at the University of Oxford, Davies for many years  edited the Peterborough (Ont.) Examiner and taught at the University of  Toronto. He is best known for three trilogies: the Deptford trilogy con�  sists of Fifth Business (1970), The Manticore (1972), and World of Won�  ders (1975), novels examining the intersecting lives of three men from a  small Canadian town; the Salterton trilogy, three comedies of manners set  in a provincial university town; and the so-called Cornish trilogy� The  Rebel Angels (1981), What�s Bred in the Bone (1985), and The Lyre of  Orpheus (1988). Davies�s novels are notable for satirizing bourgeois pro�  vincialism and exploring the relationship between mysticism and art.</p><p>Davis, Angela (Yvonne) (b. Jan. 26, 1944, Birmingham, Ala., U.S.)  U.S. political activist. She was a doctoral candidate at the University of  California at San Diego, studying under Herbert Marcuse. Because of her  radical political views, her position as lecturer in philosophy at UCLA  was not renewed. A champion of the cause of black prisoners, she grew  particularly attached to George Jackson, a member of the so-called  Soledad Brothers (after Soledad Prison). After an abortive courtroom  escape and kidnapping attempt in August 1970 in which four people,  including Jackson�s brother and the trial judge, were killed, Davis was  suspected of involvement, and she became one of the Federal Bureau of  Investigation�s most-wanted criminals. Arrested in New York City in  October, she was acquitted of charges of murder, kidnapping, and con�  spiracy by an all-white jury. In 1980 she ran unsuccessfully for vice presi�  dent on the Communist Party ticket. In 1991 Davis became a professor  at the University of California at Santa Cruz.</p><p>Davis, Benjamin O(liver), Jr. (b. Dec. 18, 1912, Washington, D.C.,  U.S.�d. July 4, 2002, Washington, D.C.)

He  organized the 99th Fighter Squadron, the first all-black air unit, and in  1943 he organized and commanded the Tuskegee Airmen. He flew 60 com�  bat missions. In 1948 Davis helped plan the desegregation of the Air  Force, and he later commanded a fighter wing in the Korean War. After  retiring as lieutenant general in 1970, he was named director of civil avia�  tion security in the U.S. Department of Transportation (1971-75).

Self-taught as a conductor, he first earned acclaim with  a 1958 production of Mozart�s opera The Abduction from the Seraglio.  His reputation was established when he filled in for Otto Klemperer the  next year. He was music director of Co vent Garden (1971-86) and prin�  cipal conductor of the Bavarian Radio Symphony (1983-92); he was  appointed principal conductor of the London Symphony Orchestra in  1995. He has a special affinity for the music of Hector Berlioz and Jean  Sibelius.</p><p>Davis, David (b. March 9, 1815, Cecil county, Md., U.S.�d. June 26,  1886, Bloomington, Ill.) U.S. jurist. He earned a law degree from Yale in  1835 and established a law practice in Bloomington the following year.  He was elected to the Illinois legislature in 1844. As a state circuit-court  judge (1848-62) he became a close friend of Abraham Lincoln, and he  worked assiduously for Lincoln�s election as president in 1860. In 1862  Lincoln appointed him to the Supreme Court of the United States (1862�  77). He resigned his seat on the court to accept election to the U.S. Sen�  ate (1877-83).</p><p>Davis, Jefferson (b. June 3, 1808, Christian county, Ky., U.S.�d.  Dec. 6, 1889, New Orleans, La.) U.S. political leader, president of the  Confederate States of America (1861-65). He graduated from West Point  and served as a lieutenant in the Wisconsin Territory and later in the Black  Hawk War. In 1835 he became a planter in Mississippi. Elected to the  U.S. House of Representatives (1845-46), he resigned to serve in the  Mexican War, in which he distinguished himself at the Battle of Buena  Vista. A national hero, he served in the U.S. Senate (1847-51) and as Pres.  Franklin Pierce�s secretary of war (1853-57). He returned to the Senate in  1857, where he advocated states' rights but tried to discourage secession.  After Mississippi seceded in 1861, he resigned and was chosen president  of the Confederacy. He conducted the South�s war effort despite short�  ages of manpower, supplies, and money and opposition from radicals  within his administration. After Gen. Robert E. Lee surrendered without  Davis�s approval in April 1865, Davis fled Richmond, Va., the Confed�  erate capital, hoping to continue the fight until he could secure better terms  from the North. Captured and indicted for treason, he was never tried.  After two years imprisonment, he was released in poor health in 1867. He  retired to Mississippi. His citizenship was restored posthumously in 1978.</p><p>Davis, Miles (Dewey) (b. May 26, 1926, Alton, Ill., U.S.�d. Sept.  28, 1991, Santa Monica, Calif.) U.S.  trumpeter and bandleader. Davis  grew up in East St. Louis, Mo., and  began study at the Juilliard School in  New York City in 1944. He worked  with Charlie Parker (1946-48). His  early efforts as a bandleader resulted  in recordings known as Birth of the  Cool (1949), in which a relaxed aes�  thetic replaced the more frenetic  bebop with the �cool jazz� of the  1950s. From 1955 Davis�s groups  framed his spare, lyrical approach in  contrast to the dense complexity of  saxophonists such as John Coltrane  and Wayne Shorter. His dark, brooding tone, logically paced improvisa�  tions, and frequent use of the metal mute were major influences on jazz  trumpet soloists. The 1959 album Kind of Blue was a pioneering example  of modal harmonic jazz. His music became more aggressive during the  1960s, and his use of electronic instruments by the end of the decade  (.Bitches Brew, 1969) gave rise to the jazz-rock fusion of the 1970s. Davis  was one of the most original and influential jazz musicians.</p><p>Davis, Stuart (b. Dec. 7, 1894, Philadelphia, Pa., U.S.�d. June 24,  1964, New York, N.Y.) U.S. abstract painter. His father was a graphic art�  ist who encouraged his interest in art. He studied in New York City with  Robert Henri (1909-12), made drawings for the periodical The Masses,</p><p>associated with the Ash Can school, and exhibited in the Armory Show.  A visit to Paris in 1928-29 inspired his own version of Cubism; he began  rearranging natural forms from everyday life into flat posterlike patterns  with sharp outlines and contrasting colours�the dissonant colours and  repetitive rhythms reflecting his interest in jazz�in a style that eventu�  ally led to totally abstract patterns. He is considered the outstanding U.S.  artist who worked in the Cubist style.</p><p>Davis Cup Trophy awarded to the winning team of an international ten�  nis tournament for men. It was donated in 1900 by Dwight F. Davis, him�  self a player in the first two matches (called ties), for a competition  between teams from the U.S. and Britain. Since then, the tournament has  developed into a truly international event. More than 100 nations have  participated, but winners have been largely confined to the U.S, Austra�  lia, France, Britain, and Sweden.</p><p>Davis Strait Strait, northern Atlantic Ocean.

It  consists of two villages, Davos-Platz and Davos-Dorf, located in a val�  ley of the Alps. First inhabited by Romansh-speaking people, it was settled  in the 13th century by German speakers. It became the capital of the  League of Ten Jurisdictions (or Courts) in 1436 and was ruled by Austria  from 1477 to 1649. After the 1860s it became a fashionable health resort,  and in the 20th century it developed into a centre for skiing and other  winter sports. In the 1990s Davos became famous for hosting the World  Economic Forum, an annual gathering of international politicians and fin�  anciers who represented a transnational elite.</p><p>Davout \da-'vii\, Louis-Nicolas, Prince d'Eckmuhl Ndek-'mlelX  (b.

Despite his noble origins, in 1790 he led his  regiment in a pro-Revolutionary revolt, and he performed with merit in  the Belgian campaign of 1792-93. He accompanied Napoleon to Egypt  (1798-99) and was promoted to division general. As a coips commander,  he had a significant impact on the victories at Austerlitz (1805), Auerstedt  (1806), Jena (1806), Eylau (1807), Eckmtihl (1809), and Wagram (1809).

May 29, 1829, Geneva, Switz.) English chemist. By his early 20s his work  on gases had established his reputation. His discovery of the anesthetic  effect of nitrous oxide in 1799 was a major contribution to surgery. He also  did early research on voltaic cells and batteries, tanning, electrolysis, and  mineral analysis. In Elements of Agricultural Chemistry (1813) he became  the first to apply chemical principles systematically to farming. He was  the first to isolate potassium, sodium, barium, strontium, magnesium, and cal�  cium; he also discovered boron and studied chlorine and iodine extensively.  He analyzed many pigments and proved that diamond is a form of carbon.  He was one of the greatest exponents of the scientific method. His research  on mine explosions and flame and his invention of the safety lamp brought  him great prestige, and in 1820 he was made president of the Royal Soci�  ety of London.</p><p>daw See jackdaw</p><p>Dawenkou culture \'da-wen-,ko\ or Ta-wen-k'ou culture Chi�  nese Neolithic culture of c. 4500-2700 bc.

Grants of 80 to 160 acres were offered to each  Indian head of household, though actual ownership was withheld for 25  years to guard against sales to speculators. The unintended result was a  weakened tribal structure, the inability of many nomadic Indians to adjust  to an agrarian existence, and a reservation life of poverty, disease, and  despondency. Under the provision that made available for public sale any  �surplus� reservation land, whites had acquired two-thirds of the Indian  land by 1932.</p><p>Dawes Plan (1924) Arrangement for Germany�s payment of repara�  tions to the Allies after World War I, produced by a committee of experts  presided over by Charles Dawes.

It states that world  peace is impossible unless a ruler first regulates his own country, but that  no ruler can do this without first setting his own household in order, which  requires personal virtue.

The sidereal day (see sidereal  period) is the time required for the Earth to rotate once relative to the  background of the stars (i.e., the time between two observed passages of  a star over the same meridian of longitude). The apparent solar day is the  time between two successive transits of the Sun over the same meridian.  Because the orbital motion of the Earth makes the Sun seem to move  slightly eastward each day relative to the stars, the solar day is about four  minutes longer than the sidereal day. The mean solar day is the average  value of the solar day, which changes slightly in length during the year  as the Earth�s speed in its orbit varies. See table opposite.</p><p>Day, Doris orig.

She made  her film debut in 1948 and starred in musicals such as Calamity Jane  (1953), Young at Heart (1955), and The Pajama Game (1957). Playing a  sunny, wholesome girl-next-door type, she embodied the idealized Ameri�  can woman of the 1950s. She played dramatic roles in Love Me or Leave  Me (1955) and The Man Who Knew Too Much (1956) before starring in</p><p>bedroom comedies such as Pillow Talk (1959) and That Touch of Mink  (1962).

In 1916 she  returned to New York to work for the radical journals The Call and The  Masses. With the birth of her daughter (1927), she broke her ties with  radicalism and converted to Roman Catholicism. After writing for the lib�  eral Catholic journal Commonweal, in 1933 she and Peter Maurin (1877�  1949) cofounded The Catholic Worker, which expressed her view of  �personalism.� She sought to aid the poor by establishing urban �hospi�  tality houses� as part of the Catholic Worker movement. After Maurin�s  death, she continued to publish the paper and manage the hospitality  houses. Although her outspoken pacifist views were criticized by Catho�  lic conservatives, she influenced Catholic liberals such as Thomas Merton  and Daniel and Phiup Berrigan.</p><p>Day-Lewis, C(ecil) (b. April 27, 1904, Ballintubbert, County Leix,  Ire.�d. May 22, 1972, Hadley Wood, Hertfordshire, Eng.) Irish-born  British poet. Son of a clergyman, Day-Lewis studied at the University of  Oxford and in the 1930s became part of a circle of left-wing poets cen�  tred on W.H. Auden, though he later turned to an individual lyricism  expressed in traditional forms. His works include translations of Virgil�s  Georgies (1940), Aeneid (1952), and Eclogues (1963) and the verse col�  lections The Room (1965) and The Whispering Roots (1970). He also  wrote the autobiography The Buried Day (1960) and several detective  novels under the pseudonym Nicholas Blake. He became poet laureate of  England in 1968.

Dayak is a generic  term that has no precise ethnic or tribal significance but distinguishes the  indigenous people from the largely Malay population of the coastal areas.  Most Dayaks are riverine people who live in small longhouse communi�  ties. Children live with their parents until marriage, and boys, who usu�  ally seek brides outside their own village, go to live in their wife�s  community. Their subsistence economies rest on the shifting cultivation  of hill rice, supplemented by fishing and hunting. They number more than  two million.</p><p>Dayan \dl-'an\, Moshe (b. May 20, 1915, Deganya, Palestine�d. Oct.  16, 1981, Tel Aviv-Yafo, Israel) Israeli soldier and statesman. Born of  Russian parents in Israel�s first kibbutz, he became a guerrilla fighter  against Arab raiders during the period of the British mandate. Although  jailed briefly by the British for his involvement with the Hagana organi�  zation, he lost an eye fighting alongside British forces in Syria during  World War II (1939�45). He was a commander in the Israeli army during  the first Arab-Israel war (1948-49). He was army chief of staff during the  Suez Crisis (1956) and later agriculture minister (1959-64). He was  appointed defense minister just before the Six-Day War (1967), and the  Israeli victory brought him widespread adulation; he served until 1974.  He joined the Likud party government as foreign minister when it came  into power in 1977 and helped broker the 1978 Camp David Accords.</p><p>Dayananda Sarasvati Xdo-'ya-non-do-.so-ros-'vo-teV orig.

A Brahman, he rejected  what he considered idol worship at age 14 after seeing mice swarm over  an image of Shiva, attracted by offerings placed before it. His religious  quest led him to Yoga, and, to escape an arranged marriage, he joined the  ascetic Sarasvati order. He spent 15 years traveling in search of religious  truth, and in 1863 he began preaching his vision of reinstating a purified  Vedic religion. He debated orthodox Hindu scholars and Christian mis�  sionaries and in 1875 founded Arya Samaj. He opposed child marriage  and the ban on remarriage by widows, and he opened Vedic study to all  castes.</p><p>daylight saving time System for uniformly advancing clocks, espe�  cially in summer, so as to extend daylight hours during conventional  waking time.

The 1829 open�  ing of the Miami and Erie Canal between Dayton and Cincinnati and the  1851 arrival of the railroad stimulated its industrial growth. It was home  to Wilbur and Orville Wright and is also their place of burial. The city is  a market and distribution centre. It is the site of Wright-Patterson Air  Force Base (established 1946) and the Air Force Institute of Technology  (1947). Home to several colleges and universities, it also has an art insti�  tute and a symphony orchestra.</p><p>Daytona Beach Coastal city (pop., 2000: 64,112), northeastern  Florida, U.S. Located south of Jacksonville, it was founded by Mathias  Day in 1870 and incorporated in 1876.

June 13, 1948, Tokyo) Japanese  novelist. At the end of World War II he emerged as the literary voice of  his time, capturing the period of postwar confusion when traditional val�  ues were discredited. The son of a wealthy landowner and politician, he  often used his background as material in his fiction. Tsugaru (1944) is  perhaps his best novel. His postwar works� The Setting Sun (1947), Vil�  lon�s Wife (1947), and No Longer Human (1948)�were increasingly  despairing in tone, reflecting the crisis that led to his suicide at age 38.</p><p>DC See direct current</p><p>DDT in full dichlorodiphenyltrichloroethane Synthetic insecticide  belonging to the family of organic halogens. In 1939 its toxicity to a wide  variety of insects was discovered (by Paul Hermann Muller, who was  awarded a Nobel Prize for his work) and effectively used against many  disease vectors. By the 1960s, many species of insects had developed  populations resistant to DDT; meanwhile, this highly stable compound  was accumulating along the food chain and having toxic effects on vari�  ous birds and fishes. During the 1960s it and similar chemicals were found  to have severely reduced the populations of certain birds, including the  bald eagle.</p><p>de or te Vde\ Chinese "virtue" In Daoism, the potentiality of dao that  is present in all things; in Confucianism, the virtue of internal goodness  and propriety. In both systems it is regarded as the active principle of dao ,  and it is thus the life or moral principle. In the Daodejing, de is described  as the unconscious functioning of the physical self, which can live har�  moniously with nature. Personal de is thought to flourish when one aban�  dons ambition and the spirit of contention for a life of naturalness, leading  to an awareness of the underlying unity that permeates the universe.</p><p>De Beers Consolidated Mines World�s largest producer and dis�  tributor of diamonds. Diamonds were first discovered in southern Africa  in the mid 1860s on the de Beer farm. The urban centre that resulted is  now known as Kimberley. Two diamond mines dug there (no longer in  operation) were at one time the world�s most productive. Cecil Rhodes  bought a claim to the De Beers mine in 1871, and eventually bought  claims to most of southern Africa�s diamond mines. To keep prices high  and demand steady, he formed the London Diamond Syndicate in the  1890s as a means of limiting the supply of diamonds reaching the mar�  ket. Renamed the Central Selling Organization (CSO), it came to control  nearly 80% of the world diamond trade by the late 1980s. Dwindling  demand caused the CSO to be replaced by the Diamond Trading Com�  pany (DTC) in 2000. It was among the first companies in South Africa  to sponsor drug treatments for its workers infected with HIV. De Beers  also has interests in synthetic diamonds, minerals and ores, and in min�  ing production and processing equipment. Through its large market share  and its willingness to work with competitors, De Beers has continued to  influence the price and availability of diamonds worldwide, prompting  accusations that it has engaged in unfair trading practices. A controlling  interest in the company is held by Anglo American PLC.</p><p>de Colmar Vdi-'kol-.marV Charles Xavier Thomas (b. 1785, Col�  mar, Fr.�d. 1870, Paris) French mathematician.

After earn�  ing a Ph.D. from Yale University, he founded the De Forest Wireless  Telegraph Co. (1902) and the De Forest Radio Telephone Co. (1907). In  1907 he patented the Audion vacuum tube detector, which allowed more  sensitive reception of radio signals such as his live broadcast of a perfor�  mance by Enrico Caruso (1910). He developed a sound-on-film optical-  recording system called Phonofilm and demonstrated it in theatres (1923�  27). A poor businessman who was twice defrauded by business partners,  he eventually sold his patents at low prices to such firms as American  Telephone &amp; Telegraph Co., which profited highly from their commercial</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>520 I De Gasperi &#x25BA; De Leon</p><p>development.

He served in the Austrian  parliament (1911-19) and sought the annexation of his native region of  Tyrol to Italy. He later served in the Italian parliament (1921-27) as one  of the founders of the Italian Popular Party. After 16 months� imprison�  ment as an antifascist, he became a Vatican librarian in 1929. In World  War II he was active in the Resistance, and after the fall of the fascist  regime he became leader of the newly formed Christian Democratic Party.  As prime minister (1945-53), he enacted a new constitution, instituted  land reform, and oversaw Italy�s postwar economic reconstruction. Under  his leadership Italy joined NATO, and he helped organize the Council of  Europe and the European Coal and Steel Community.</p><p>de Gaulle, Charles (-Andre-Marie-Joseph) (b. Nov. 22, 1890,  Lille, France�d. Nov. 9, 1970, Colombey-les-Deux-Eglises) French sol�  dier, statesman, and architect of France�s Fifth Republic. He joined the army  in 1913 and fought with distinction in World War I. He was promoted to  the staff of the supreme war council in 1925. In 1940 he was promoted  to brigadier general and served briefly as undersecretary of state for  defense under Paul Reynaud. After the fall of France to the Germans, he  left for England and started the Free French movement. Devoted to France  and dedicated to its liberation, he moved to Algiers in 1943 and became  president of the French Committee of National Liberation, at first jointly  with Henri-Honore Giraud. After the liberation of Paris, he returned and  headed two provisional governments, then resigned in 1946. He opposed  the Fourth Republic, and in 1947 he formed the Rally of the French People  (RPF), but severed his connections with it in 1953. He retired from pub�  lic life and wrote his memoirs. When an insurrection in Algeria threat�  ened to bring civil war to France, he returned to power in 1958, as prime  minister with powers to reform the constitution. That same year he was  elected president of the new Fifth Republic, which ensured a strong presi�  dency. He ended the Algerian War and transformed France�s African ter�  ritories into 12 independent states. He withdrew France from NATO, and  his policy of neutrality during the Vietnam War was seen by many as anti-  Americanism. He began a policy of detente with Iron Curtain countries  and traveled widely to form a bond with French-speaking countries. After  the civil unrest of May 1968 by students and workers, he was defeated  in a referendum on constitutional amendments and resigned in 1969.</p><p>De Grey River \do-'gra\ River, northwestern Western Australia.

Settling  in Hoboken, N.J., he supported himself as a house painter before moving  to New York City, where he came under the influence of Arshile Gorky.  He supported himself by working for the WPA Federal Art Project. In the  1930s and �40s his work was both figurative and abstract; the two ten�  dencies eventually fused in images that combined biomorphic and geo�  metric shapes. In the 1940s he became one of the leading exponents of  Abstract Expressionism and particularly of action painting. Among his best-  known works is a series of deliberately vulgar images of women done  with roughly applied pigment and raw colours (e.g., Woman /, 1950-52;  Woman and Bicycle, 1953).

In 1924 he founded Fianna</p><p>Fail, which won the 1932 elections. As prime minister (1932-48), he took  the Irish Free State out of the British Commonwealth and made his coun�  try a �sovereign� state, renamed Ireland, or Eire. He proclaimed Ireland  neutral in World War II. After twice serving again as prime minister  (1951-54, 1957-59), he became president of Ireland (1959-73).</p><p>de Valois \d3-val-'wa\, Dame Ninette orig.

She founded  the Academy of Choreographic Art in 1926 to teach movement to actors  and cofounded the Camargo Society in 1930. In 1931 she founded and  directed the Vic-Wells Ballet; this became the Sadler�s Wells Ballet  (1946-56) and later the Royal Ballet (1956), which she directed until  1963.

De Voto taught at Northwestern and Harvard universities,  briefly edited The Saturday Review (1936-38), and wrote a column for  Harper�s (1935-55). Known for his works on American literature and the  history of the western frontier as well as for his vigorous, outspoken style,  he was one of the most widely read critics and historians of his day.

He taught at the University of Amsterdam (1878-1918), where he intro�  duced the experimental study of organic evolution. His rediscovery in  1900 (simultaneously with Carl Erich Correns and Erich Tschermak von  Seysenegg) of Gregor Mendel�s principles of heredity and his own theory  of biological mutation explained concepts about the nature of variation of  species that made possible the universal acceptance and active investiga�  tion of Charles Darwin�s theory of organic evolution. De Vries discovered  and named the phenomenon known as mutation, and he also contributed  to knowledge of the role of osmosis in plant physiology.

A New York City socialite, she worked as a professional actress  (1890-1904) before becoming a designer. Her design principles of sim�  plicity, airiness, and visual unity helped change the fashion of interior  design away from Victorian ornamentation. She was the first female pro�  fessional interior designer in the U.S. She spent much of her life in France  as a noted hostess.

In 1937 he teamed with his brother Paul (nicknamed �Daffy�) to  pitch the Cardinals to a World Series victory; he won 30 games and lost  7 that year and remains the last 30-game winner in the National League.  He developed arm trouble the same year and never fully regained his form.  He ended his career with the Chicago Cubs after being traded for the 1938  season. He was known for his colourful personality, which, after his retire�  ment at age 30, served him well as a broadcaster.</p><p>Dean, James (Byron) (b. Feb. 8, 1931, Marion, Ind., U.S.�d.

Richard Nixon. In 1972 Nixon  asked Dean to investigate whether White House personnel were involved  in the Watergate Hotel break-in (see Watergate scandal). Dean refused to  issue a proposed fictitious report denying a cover-up. When indications of  White House involvement grew stronger, he began telling federal investi�  gators what he knew. Nixon fired him in April 1973; two months later Dean  testified before a Senate committee about obstruction of justice by White  House officials, including the president. He spent four months in prison for  his role in the Watergate cover-up. His revelations contributed to Nixon�s  decision to resign in 1974.</p><p>Deane, Silas (b. Dec. 24, 1737, Groton, Conn.�d.

Given his effect on such composers as Maurice  Ravel, Igor Stravinsky, Bela Bartok, Alban Berg, Anton Webern, and Pierre  Boulez, he can be seen as the most influential French composer of the last  three centuries. His works include the opera Pelleas et Melisande (1902),  the orchestral works Prelude to The Afternoon of a Faun (1894) and La  Mer (1905), and the piano Preludes (1910, 1913).</p><p>Debye \d3-'bl\, Peter orig.

Many nonpoets, including the novelist Joris-Karl Huysmans and the artist  Aubrey Beardsley, are also often associated with the Decadents. The Deca�  dents emphasized art for art�s sake (see Walter Pater), seeing it as autono�  mous and opposed to nature and to the materialistic preoccupations of  industrialized society, and therefore stressed the bizarre, incongruous, and  artificial in both their work and their lives.</p><p>Decansky, Stefan See Stefan Decansky</p><p>decapod Any of more than 8,000 species (order Decapoda) of crusta�  ceans having five pairs of legs attached to the thorax.

Its principal rivers, the Godavari,  Krishna, and Kaveri (Cauvery), flow from the Western Ghats eastward to  the Bay of Bengal. Its early inhabitants were a Dravidian-speaking popu�  lation not reached by the 2nd-millennium-BC Aryan invasion. Ruled by  Mauryan (4th-2nd centuries bc) and Gupta (4th-6th centuries ad) dynas�  ties, it became an independent Muslim kingdom in 1347. Later split up  into five Muslim sultanates, the Deccan was largely conquered by the  Mughal dynasty in the 17th century.

Because it requires about  a tenfold increase in power for a sound to register twice as loud to the  human ear, a logarithmic scale is useful for comparing sound intensity.  Thus, the threshold of human hearing (absolute silence) is assigned the  value of 0 dB and each increase of 10 dB corresponds to a tenfold increase  in intensity and a doubling in loudness.

Such a problem is specified by a set of possible states of the environment  or possible initial conditions; a set of available experiments and a set of</p><p>possible outcomes for each experiment, giving information about the state  of affairs preparatory to making a decision; a set of available acts depend�  ing on the experiments made and their consequences; and a set of pos�  sible consequences of the acts, in which each possible act assigns to each  possible initial state some particular consequence. The problem is dealt  with by assessing probabilities of consequences conditional on different  choices of experiments and acts and by assigning a utility function to the  set of consequences according to some scheme of value or preference of  the decision maker. An optimal solution consists of an optimal decision  function, which assigns to each possible experiment an optimal act that  maximizes the utility, or value, and a choice of an optimal experiment.

Of uncertain origins, he served as senator, consul,  and provincial military commander before taking the throne from Philip  the Arabian. He resisted the Gothic invasion of Moesia and instituted the  first organized persecution of Christians throughout the empire (250),  which only served to strengthen the Christian cause. He ended the per�  secutions in 251, shortly before he was defeated and killed by the Goths.</p><p>Declaration of Independence (July 4, 1776) Document approved  by the Continental Congress that announced the separation of 13 North  American British colonies from Britain. The armed conflict during the  American Revolution gradually convinced the colonists that separation  from Britain was essential. Several colonies instructed their delegates to  the Continental Congress to vote for independence. On June 7, Richard  Henry Lee of Virginia offered a resolution for independence. The congress  appointed Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sher�  man, and Robert R. Livingston to draft a declaration. Jefferson was per�  suaded to write the draft, which was presented with few changes on June  28. It began with a declaration of individual rights and then listed the acts  of tyranny by George III that formed the justification for seeking inde�  pendence. After debate and changes to accommodate regional interests,  including deletion of a condemnation of slavery, it was approved on July  4 as �The Unanimous Declaration of the Thirteen United States of  America.� It was signed by Congress president John Hancock, printed,  and read aloud to a crowd assembled outside, then engrossed (written in  script) on parchment and signed by the 56 delegates.</p><p>Declaration of the Rights of Man and of the Citizen Mani�  festo adopted by France�s National Assembly in 1789, which contained  the principles that inspired the French Revolution. One of the basic char�  ters of human liberties, it served as the preamble to the Constitution of  1791. Its basic principle was that �all men are born free and equal in  rights,� specified as the rights of liberty, private property, the inviolabil�  ity of the person, and resistance to oppression. It also established the prin�  ciple of equality before the law and the freedoms of religion and speech.  The Declaration represented a repudiation of the pre-Revolutionary  monarchical regime.</p><p>Declaratory Act (1766) Declaration by the British Parliament that  accompanied repeal of the Stamp Act. It stated that Parliament�s author�  ity was the same in America as in Britain and asserted Parliament�s author�  ity to make laws binding on the American colonies.</p><p>declaratory judgment In law, a judgment merely declaring a right  or establishing the legal status or interpretation of a law or instrument. It  is binding but is distinguished from other judgments or court opinions in  that it includes no executive element (an order that something be done);  instead it simply declares or defines rights to be observed or wrongs to  be eschewed by litigants, or expresses the court�s view on a contested  question of law.</p><p>decolonization Process by which colonies become independent of the  colonizing country. Decolonization was gradual and peaceful for some  British colonies largely settled by expatriates but violent for others, where  native rebellions were energized by nationalism. After World War II, Euro�  pean countries generally lacked the wealth and political support neces�  sary to suppress faraway revolts; they also faced opposition from the new  superpowers, the U.S. and the Soviet Union, both of which had taken  positions against colonialism. Korea was freed in 1945 by Japan�s defeat  in the war. The U.S. relinquished the Philippines in 1946. Britain left India  in 1947, Palestine in 1948, and Egypt in 1956; it withdrew from Africa  in the 1950s and �60s, from various island protectorates in the 1970s and  �80s, and from Hong Kong in 1997.

Small amounts of the gases in air are dissolved in body tis�  sues. When pilots of unpressurized aircraft go to high altitudes or when  divers breathing compressed air return to the surface, external pressure on  the body decreases and the gases come out of solution. Rising slowly  allows the gases to enter the bloodstream and be taken to the lungs and  exhaled; with a quicker ascent, the gases (mostly nitrogen) form bubbles  in the tissues. In the nervous system, they can cause paralysis, convul�  sions, motor and sensory problems, and psychological changes; in the  joints, severe pain and restricted mobility (the bends); in the respiratory  system, coughing and difficulty breathing. Severe cases include shock.  Recompression in a hyperbaric chamber followed by gradual decompres�  sion cannot always reverse tissue damage.</p><p>deconstruction Method of philosophical and literary analysis, derived  mainly from the work of Jacques Derrida, that questions the fundamental  conceptual distinctions, or �oppositions,� in Western philosophy through  a close examination of the language and logic of philosophical and liter�  ary texts. Such oppositions are characteristically �binary� and �hierarchi�  cal,� involving a pair of terms in which one member of the pair is assumed  to be primary or fundamental, the other secondary or derivative; examples  include nature/culture, speech/writing, and mind/body. To �deconstruct�  an opposition is to explore the tensions and contradictions between the  hierarchical ordering assumed in the text and other aspects of the text�s  meaning, especially its figurative or performative aspects. The decon�  struction �displaces� the opposition by showing that neither term is pri�  mary; the opposition is a product, or �construction,� of the text rather than  something given independently of it. The speech/writing opposition,  according to which speech is �present� to the speaker or author and writ�  ing �absent,� is a manifestation of what Derrida calls the �logocentrism�  of Western culture�i.e., the general assumption that there is a realm of  �truth� existing prior to and independent of its representation by linguis�  tic signs. In polemical discussions about intellectual trends of the late 20th  century, deconstruction was sometimes used pejoratively to suggest nihil�  ism and frivolous skepticism. In popular usage the term has come to mean  a critical dismantling of tradition and traditional modes of thought. See  also postmodernism; poststructuralism.</p><p>Decoration Day See Memorial Day</p><p>decorative arts Arts concerned with the design and decoration of  objects that are utilitarian rather than purely aesthetic, including ceramics,  glassware, basketry, jewelry, metalwork, furniture, and textiles. The separa�  tion of the decorative arts from the fine arts is a modern distinction.</p><p>deduction In logic, a type of inference or argument that purports to be  valid, where a valid argument is one whose conclusion must be true if its  premises are true (see validity). Deduction is thus distinguished from induc�  tion, where there is no such presumption. Valid deductive arguments may  have false premises, as demonstrated by the example: �All men are mor�  tal; Cleopatra is a man; therefore, Cleopatra is mortal.� Invalid deductive  arguments sometimes embody formal fallacies (i.e., errors of reasoning  based on the structure of the propositions in the argument); an example  is �affirming the consequent�: �If A then B; B; therefore, A� (see fallacy;  FORMAL AND INFORMAL).</p><p>deed See escrow</p><p>Deep Blue Computer chess-playing system designed by IBM.

The deepest known depres�</p><p>sion of this kind is the Mariana Trench. Most trenches occur at subduction  zones, where one tectonic plate is thrust under another.</p><p>deep-sea vent Hydrothermal (hot-water) vent formed on the ocean  floor when seawater circulates through hot volcanic rocks, often located  where new oceanic crust is being formed. Vents also occur on submarine  volcanoes. In either case, the hot solution emerging into cold seawater  precipitates mineral deposits that are rich in iron, copper, zinc, and other  metals. Outflow of these heated waters probably accounts for 20% of the  Earth�s heat loss. Exotic biological communities are now known to exist  around the vents; these ecosystems are totally independent of energy from  the Sun, depending not on photosynthesis but rather on chemosynthesis  by sulfur-fixing bacteria.</p><p>deer Any of the ruminants in the family Cervidae, which have two large  and two small hooves on each foot and antlers on the males of most spe�  cies and on the females of some species. Deer live mainly in forests but  may be found in deserts, tundra, and swamps and on high mountainsides.  They are native to Europe, Asia, North America, South America, and  northern Africa and have been introduced widely elsewhere. Females are  usually called does, and males bucks. Deer range in shoulder height from  the 12-in. (30-cm) pudu (genus Pudu ) to the 6.5-ft (2-m) moose. They  typically have a compact body, short tail, and long, slender ears. They  shed their antlers each year, and new ones grow in. The general form of  the antler varies among species. Deer feed on grass, twigs, bark, and  shoots. They are hunted for their meat, hides, and antlers.

They often outnumber all other mammals in an area. Deer mice are 3-6.5  in. (8-17 cm) long (excluding the long tail) and have large eyes, soft fur,  and relatively large ears. Colours range from white to brown or blackish,  with white underparts and feet. They eat plant and animal matter and nest  in burrows or trees. Clean, easily cared for, and prolific, they are often  used as laboratory animals.</p><p>Deere, John (b. Feb. 7. 1804, Rutland, Vt� U.S.�d. May 17, 1886,  Moline, Ill.) U.S. inventor and manufacturer of agricultural implements.  He was apprenticed to a blacksmith and later set up his own smithy and  moved to Illinois. There he found, through the frequent repairs he had to  make, that wood and cast-iron plows, used in the eastern U.S. from the  1820s, were unsuited to the heavy, sticky prairie soils. By 1838 he had  sold three steel plows of his own design; by 1846 he had sold about 1,000,  and by 1857 10,000. In 1868 Deere &amp; Co. was incorporated, and it went  on to become the largest U.S. manufacturer of farm machinery.</p><p>defamation In law, issuance of false statements about a person that  injure his reputation or that deter others from associating with him. Libel  and slander are the legal subcategories of defamation. Libel is defama-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>526 I defecation &#x25BA; Degas</p><p>tion in print, pictures, or any other visual symbols. A libel plaintiff must  generally establish that the alleged libel refers to him or her specifically,  that it was published to others (third parties), and that some injury  occurred as a result. The U.S. Supreme Court has ruled that public per�  sons (e.g., celebrities or politicians) alleging libel may recover damages  only if they prove that the statement in question was made with �actual  malice��i.e., with knowledge that it was false or with reckless disregard  for the truth (New York Times v. Sullivan, 1964). Slander is defamation  by oral communication. An action for slander may be brought without  alleging and proving special injury if the statement has a plainly harmful  character, as by imputing to the plaintiff criminal guilt, serious sexual  misconduct, or a characteristic negatively affecting his business or pro�  fession. The defense in defamation cases often takes the form of seeking  to establish the truth of the statements in question.</p><p>defecation \,def-3-'ka-sh9n\ or bowel movement Elimination of  feces from the digestive tract. Peristalsis moves feces through the colon to  the rectum, where they stimulate the urge to defecate. The rectum short�  ens, pushing the feces into the anal canal, where internal and external  sphincters allow them to be passed or retained. Chest, abdominal, and  pelvic muscles are used to pass them. Long delay of defecation causes  constipation and hardened feces. See also diarrhea, incontinence.</p><p>defense economics Field of national economic management con�  cerned with peacetime and wartime military expenditures. It arose in  response to the greater scale and sophistication of warfare in the 20th  century. Most nations seek to avoid the vast financial and human costs of  war�which include the lost earnings of those killed or injured, lifetime  medical care needed for those permanently incapacitated, and losses to  the economy caused by diverting resources from investments in future  economic capacity�by maintaining a level of military preparedness suf�  ficient to deter aggressors. Peacetime defense economics focuses on issues  of allocation of resources between the military and civilian sectors, the  relative size and character of the various armed forces, and the choice and  design of their weapons.</p><p>defense mechanism In psychoanalytic theory, an often unconscious  mental process (such as repression) that makes possible compromise solu�  tions to personal problems or conflicts. The compromise generally  involves concealing from oneself internal drives or feelings that threaten  to lower self-esteem or provoke anxiety. The term was first used by Sig�  mund Freud in 1894. The major defense mechanisms are repression, the  process by which unacceptable desires or impulses are excluded from con�  sciousness; reaction formation, a mental or emotional response that rep�  resents the opposite of what one really feels; projection, the attribution of  one�s own ideas, feelings, or attitudes (especially blame, guilt, or sense of  responsibility) to others; regression, reversion to an earlier mental or  behavioral level; denial, the refusal to accept the existence of a painful  fact; rationalization, the substitution of rational and creditable motives for  the true (but threatening) ones; and sublimation, the diversion of an instinc�  tual desire or impulse from its primitive form to a more socially or cul�  turally acceptable form. See also ego; neurosis; psychoanalysis.</p><p>deficit financing In government, the practice of spending more money  than is received as revenue, the difference being made up by borrowing  or minting new funds. The term usually refers to a conscious attempt to  stimulate the economy by lowering tax rates or increasing government  expenditures. Critics of deficit financing regularly denounce it as an  example of shortsighted government policy. Advocates argue that it can  be used successfully in response to a recession or depression, proposing  that the ideal of an annually balanced budget should give way to that of  a budget balanced over the span of a business cycle. See also John May�  nard Keynes; national debt.</p><p>definition In philosophy, the specification of the meaning of an expres�  sion relative to a language. Definitions may be classified as lexical, osten-  sive, and stipulative. Lexical definition specifies the meaning of an  expression by stating it in terms of other expressions whose meaning is  assumed to be known (e.g., a ewe is a female sheep). Ostensive defini�  tion specifies the meaning of an expression by pointing to examples of  things to which the expression applies (e.g., green is the color of grass,  limes, lily pads, and emeralds). Stipulative definition assigns a new mean�  ing to an expression (or a meaning to a new expression); the expression  defined (definiendum) may either be a new expression that is being intro�  duced into the language for the first time, or an expression that is already  current.</p><p>deflation Contraction in the volume of available money or credit that  results in a general decline in prices. A less extreme condition is known  as disinflation. Attempts are sometimes made to bring on deflation  (through raising interest rates and tightening the money supply) in order to  combat inflation and slow the economy. Deflation is characteristic of  depressions and RECESSIONS.</p><p>Defoe \di-'fo\, Daniel orig. Daniel Foe (b. 1660, London, Eng.�d.  April 24, 1731, London) British nov�  elist, pamphleteer, and journalist. A  well-educated London merchant, he  became an acute economic theorist  and began to write eloquent, witty,  often audacious tracts on public  affairs. A satire he published resulted  in his being imprisoned in 1703, and  his business collapsed. He traveled  as a government secret agent while  continuing to write prolifically. In  1704-13 he wrote practically single-  handedly the periodical Review, a  serious and forceful paper that influ�  enced later essay periodicals such as  The Spectator. His Tour Through the  Whole Island of Great Britain, 3 vol.</p><p>(1724-26), followed several trips to  Scotland. Late in life he turned to fic�  tion. He achieved literary immortal�  ity with the novel Robinson Crusoe  (1719), which drew partly on mem�  oirs of voyagers and castaways. He is also remembered for the vivid,  picaresque Moll Flanders (1722); the nonfictional Journal of the Plague  Year (1722), on the Great Plague in London in 1664-65; and Roxana  (1724), a prototype of the modem novel.</p><p>defoliant Chemical dust or spray applied to plants to cause their leaves  to drop off prematurely. Defoliants sometimes are applied to crop plants  such as cotton to facilitate harvesting. They have also been used in war�  fare to eliminate enemy food crops and potential areas of concealment (as  in the Vietnam War). See also Agent Orange.</p><p>deforestation Process of clearing forests. Rates of deforestation are  particularly high in the tropics, where the poor quality of the soil has led  to the practice of routine clear-cutting to make new soil available for agri�  cultural use. Deforestation can lead to erosion, drought, loss of biodiver�  sity through extinction of plant and animal species, and increased  atmospheric carbon dioxide. Many nations have undertaken afforestation  or reforestation projects to reverse the effects of deforestation, or to  increase available timber. See also greenhouse effect.</p><p>deformation and flow Alteration in size or shape of a body under  the influence of mechanical forces. Flow is a change in deformation that  continues as long as the force is applied. Gases and liquids normally flow  relatively freely, while solids deform when subjected to forces. Most sol�  ids initially deform elastically (see elasticity), though rigid material such  as metals, concrete, or rocks can sustain large forces while undergoing  little deformation. If enough force is applied, even these materials will  reach their elastic limit, at which point brittle substances fracture while  ductile materials (see ductility) rearrange their internal structure, the result  being plastic deformation (see plasticity).</p><p>Degas \d3-'ga\, (Hilaire-Germain-) Edgar (b. July 19,1834, Paris,  France�d. Sept. 27, 1917, Paris) French painter, graphic artist, and sculp�  tor. The son of a wealthy banker, he entered the Ecole des Beaux-Arts in  1855. He spent much time in Italy studying and copying the Old Masters  and became a skilled draftsman, producing history paintings and portraits.  In the 1860s he was introduced to Impressionism by Edouard Manet and  gave up his academic aspirations, turning for his subject matter to the  fast-moving city life of Paris, particularly the ballet, theatre, circus, race�  track, and cafes. Influenced by Japanese prints and the new medium of  photography, he used displaced figure groupings and unfamiliar perspec�  tive to create figure groups seen informally and in movement, similar in  effect to snapshots. His fascination with the ballet and the racetrack sprang  from his interest in picturing people absorbed in the practiced movements  of their occupations. He often worked in pastel, his favourite medium,  producing series of women, bathers, ballerinas, and horse races. From c.</p><p>Daniel Defoe, engraving by M. Van  der Gucht, after a portrait by J.

In medieval Europe there were only two degrees: master (a scholar of arts  and grammar) and doctor (a scholar of philosophy, theology, medicine, or  law). The baccalaureate, or bachelor�s degree, was originally simply a  stage toward mastership. In contemporary France the baccalaureat is con�  ferred on the completion of secondary education, the licence on comple�  tion of a three- to four-year program of university study, the maitrise on  the passing of advanced examinations, and the doctoral on completion of  several years of advanced academic studies. Other contemporary degrees  include the Bachelor of Arts (B.A. or A.B.) or Bachelor of Science (B.S.)  degree, typically awarded after a four-year program of college study; the  Master of Arts (M.A.) or Master of Science (M.S.) degree, earned after a  year or two of additional study; and the Doctor of Philosophy (Ph.D.),  earned after several years of post-baccalaureate study and research. In the  mid-20th century the Associate of Arts degree (A. A.) began to be awarded  by U.S. junior colleges. Common professional degrees are the Doctor of  Jurisprudence (J.D.) and the Doctor of Medicine (M.D.). Honorary  degrees are granted without regard to academic achievement.</p><p>dehydration Method of food preservation in which moisture (prima�  rily water) is removed. Dehydration inhibits the growth of microorgan�  isms and often reduces the bulk of food. It is an ancient practice, used by  prehistoric peoples in sun-drying seeds, by North American Indians in  sun-drying meat strips, and by the Japanese in drying fish and rice. It was  used to prepare troop rations in World War II, and in recent decades  campers and relief agencies have discovered its advantages. Commercial  dehydration equipment includes tunnel dryers, kilns, and vacuum dryers.  A combination of dehydration and freezing is used in the process of  freeze-drying, whereby solid food remains frozen while its liquid escapes  as vapour. The dairy industry is one of the largest producers of dehydrated  foods, including whole milk, skim milk, and eggs.</p><p>dehydration Loss of water, almost always along with salt, from the  body, caused by restricted water intake or excessive water loss. Early  symptoms of water deprivation are thirst, decreased saliva, and impaired  swallowing. (When more electrolytes than water are lost, osmosis pulls  water into cells, and there is no thirst.) Later, tissues shrink, including the  skin and eyes. Mild fever rises as plasma volume and cardiac output  decrease, and perspiration decreases or stops, greatly reducing heat loss.  Urine output falls, and the kidneys cannot filter wastes from the blood. Irre�  versible shock can occur at this point. The cause of dehydration is treated  first; then water and electrolytes must be given in the correct proportions.</p><p>Deinarchus See Dinarchus</p><p>Deinonychus \dl-'na-ni-k9s\ Genus of clawed theropod dinosaurs that  flourished in western North America during the Early Cretaceous period  (144-99 million years ago). Deinonychus walked and ran on two legs, yet  its killing devices, large sickle-like talons 5 in. (13 cm) long on the sec�  ond toe of each foot, required it to stand on one foot while slashing at its  prey with the other. Its long, outstretched tail was enclosed in bundles of  bony rods that grew out of the tail vertebrae, making it very rigid. About  8-13 ft (2.4-4 m) long and weighing 100-150 lbs (45-68 kg), it had a  large brain and was evidently a fast, agile predator.</p><p>Deir el-Bahri See Dayr al-Bahr}</p><p>Deira Yda-re\ Anglo-Saxon kingdom, Britain.

A Druid foretold at Deirdre�s birth that  many men would die on her account, and she was raised in seclusion. A  woman of great beauty, she rejected the advances of King Conor (see  Conchobar), married Noisi, one of the sons of Usnech, and fled with him  to Scotland. Lured back to Ireland, Noisi and his brothers were murdered,  and Deirdre killed herself to avoid marrying Conor. In the 20th century  the story was dramatized by William Butler Yeats and John Millington  Synge.</p><p>Deism Belief in God based on reason rather than revelation or the teach�  ing of any specific religion. A form of natural religion, Deism originated  in England in the early 17th century as a rejection of orthodox Christian�  ity. Deists asserted that reason could find evidence of God in nature and  that God had created the world and then left it to operate under the natu�  ral laws he had devised. The philosopher Edward Herbert (1583-1648)  developed this view in On Truth (1624). By the late 18th century Deism  was the dominant religious attitude among Europe�s educated classes; it  was accepted by many upper-class Americans of the same era, including  the first three U.S. presidents.</p><p>Delacour \,del-3-'kur\, Jean Theodore (b.

After his boyhood collection of more than 1,300 live birds was  destroyed during World War I, he made expeditions worldwide and  assembled a huge new collection at the Chateau de Cleres in Normandy.  He bred pheasants in captivity, discovered and named many new bird and  mammal species, founded the magazine L�Oiseau (1920), and wrote the  standard work The Birds of French Indochina (1931).

As a young man he was strongly influenced by the Roman�  ticism of the painter Theodore Gericault and the Polish-born composer and  pianist Frederic Chopin. In 1822 he exhibited the painting Dante and Vir�  gil in Hell, a landmark in the development of French 19th-century Roman�  ticism. In his subsequent choice of subjects, Delacroix often showed an  affinity with Lord Byron and other Romantic poets of his time. His work  was characterized by an uninhibited expression of energy and movement,  a fascination with violence, destruction, and the more tragic aspects of  life, and a sensuous use of colour. After his success at the Paris Salon, he  was commissioned to decorate government buildings; he became one of  the most distinguished monumental mural painters in the history of French  art. He explored the new medium of lithography and in 1827 executed 17  lithographs for an edition of Faust. In 1830 he painted Liberty Leading  the People to commemorate the July Revolution that brought Louis- Philippe  to the French throne. His use of colour influenced the development of  Impressionism.</p><p>Liberty Leading the People, oil on canvas by Eugene Delacroix, 1830; in the Lou�  vre, Paris.</p><p>GIRAUDON/ART RESOURCE, NEW YORK CITY</p><p>Delagoa Bay V.del-o-'go-oV Bay, southeastern coast of Mozambique.

One of the first blacks admitted to Harvard Medical School (1850-51),  he later practiced in Pittsburgh. He developed a strong interest in foreign  colonization by black Americans and went to Africa to investigate sites.  He moved to Canada in 1856 and returned early in the American Civil War  to recruit for the 54th Massachusetts Volunteers, for which he also served  as surgeon. He was made a major, the first black to receive a regular army  commission. He later served in the Freedmen's Bureau.</p><p>Delany, Samuel R(ay) (b. April 1, 1942, New York, N.Y., U.S.) U.S.  science-fiction novelist and critic. Born into a distinguished African  American family, he attended the City College of New York and pub�  lished his first novel in 1962. His highly imaginative works, which gar�  nered wide critical admiration, address racial and social issues, sexuality,  heroic quests, and the nature of language. Dhalgren (1975), his most con�  troversial novel, tells of a young bisexual man searching for identity in a  large, decaying city. Other works include the novels Babel-17 (1966,  Nebula Award), The Einstein Intersection (1967, Nebula Award), and  Stars in My Pocket Like Grains of Sand (1984), and scripts for film, radio,  and Wonder Woman comic books. Among his nonfiction works are  Longer Views: Extended Essays (1996) and Shorter Views: Queer  Thoughts and the Politics of the Paraliterary (1999).</p><p>Delaunay \d3-lo-'na\, Robert  (b. April 12, 1885, Paris, Fr.�d. Oct.</p><p>25, 1941, Montpellier) French</p><p>painter. He spent his early career as  a part-time designer of stage scenery  and came under the influence of  Neo-Impressionism, Fauvism, and Cub�  ism. In 1909-11 his colour experi�  ments culminated in a series of  paintings of the Eiffel Tower, which  combined fragmented Cubist forms  with dynamic movement and vibrant  colour. The introduction of bright  colour to Cubism�a style that came  to be known as Orphism�  distinguished his work from that of  the more orthodox Cubist painters  and influenced the artists of Der  Blaue Reiter. With his wife, the  Ukrainian-born painter and textile  designer Sonia Terk Delaunay  (1885-1979), he painted abstract  mural decorations for the 1937 Paris  Exposition.</p><p>Delaware State (pop., 2000:</p><p>783,600), middle Atlantic region,</p><p>U.S. It lies on the Atlantic Ocean and  is bordered by Pennsylvania, New  Jersey, and Maryland. Covering</p><p>2,026 sq mi (5,247 sq km), its capital is Dover. Originally inhabited by  Algonquian tribes, Delaware�s first permanent white settlement was by  Swedes at Fort Christina, now Wilmington, in 1638. In 1655 New Sweden  was taken by the Dutch of New Amsterdam and in 1664 by the English.  Delaware was thereafter a part of New York until 1682, when it was ceded  to William Penn. It was governed by Pennsylvania until 1776, although it  was granted its own assembly in 1704. The first state to ratify the U.S. Con�  stitution in 1787, it is the nation�s second smallest state but one of its most  densely populated. Chemical manufacturing is the major industry, fol�  lowed by food processing. Delaware�s most important transportation artery  is the Chesapeake and Delaware Canal, deepened for ocean shipping,  which shortens the water route between Philadelphia and Baltimore.</p><p>Delaware or Lenape \le-'na-pa\ Confederation of North American  Indians living mostly in Oklahoma, U.S. Thousands more live in Wis�  consin and Kansas, U.S., and in Ontario, Can. They speak a language of  the Algonquian family. They once occupied the Atlantic seaboard from  southern Delaware to western Long Island, especially the Delaware River  valley, for which the confederation was named. To other Algonquian divi�  sions, the Lenape were the �grandfathers,� believed to be the original tribe  from which all others sprang, and they were highly respected. They  depended primarily on agriculture but also hunted and fished. They were  grouped in three clans based on maternal descent; these were in turn  divided into lineages, whose members lived together in a longhouse. They  were governed by a council of lineage sachems (chiefs), who directed the  public affairs of the community; the eldest woman of the lineage  appointed the sachem. The Delaware were the Indians most friendly to  William Penn; they were rewarded by the infamous Walking Purchase, a  treaty that deprived them of their own lands and forced them to settle on  lands assigned to the Iroquois. After 1690 they drifted westward. They  sided with the French in the French and Indian War (1754-63) and helped  defeat the British general Edward Braddock. In 1867 most of the remain�  ing Delaware were removed to Oklahoma. Some 8,300 people claimed  sole Delaware descent in the 2000 U.S. census.</p><p>Delaware Bay Inlet of the Atlantic Ocean. Forming part of the New  Jersey-Delaware state border, it extends southeast for 52 mi (84 km) from  the junction of the Delaware River with Alloway Creek to its entrance  between Cape May and Cape Henlopen. Bordered by marshy lowlands,  the bay is an important link in the Atlantic Intracoastal Waterway.</p><p>Delaware River River in Pennsylvania, Delaware, New Jersey, and  New York, U.S. Formed by the junction of its eastern and western  branches in southern New York, it flows about 405 mi (650 km) to empty  into the Atlantic Ocean at Delaware Bay. Navigable to Trenton, N.J., it is  spanned by the Commodore Barry Bridge, completed in 1974.</p><p>Delbruck Vdel-.briekV Max (b. Sept. 4, 1906, Berlin, Ger.�d. March  9, 1981, Pasadena, Calif., U.S.) German-born U.S. biologist. He received  his Ph.D. from the University of Gottingen in 1930, and in 1937 he immi�  grated to the U.S., where he joined the California Institute of Technology  faculty. In 1939 he discovered a one-step process for growing bacterioph�  ages that would induce a phage, after an hour of inactivity, to multiply to  produce several hundred thousands of progeny. In 1946 he and A.D. Her-  shey independently discovered that the genetic material of different kinds of  viruses can combine to create new types of viruses, a process previously  believed to be limited to higher, sexually reproducing forms of life. In 1969  he shared a Nobel Prize with Hershey and their colleague Salvador Luria.</p><p>Delcasse \del-ka-'sa\, Theophile (b. March 1, 1852, Pamiers,  France�d. Feb. 22, 1923, Nice) French politician. A journalist, he was  elected to the Chamber of Deputies in 1885 and served in cabinet posts  from 1893. As foreign minister in six successive governments (1898�  1905), he reached agreement with the British that led to the Entente Cor-  diale. Considered the principal architect of the new system of European  alliances formed before World War I, he also paved the way for the Anglo-  Russian agreement of 1907. He later served as minister of the marine  (1911-13) and again as foreign minister (1914-15).</p><p>Deledda \da-'lad-da\, Grazia (b. Sept. 27, 1871, Nuoro, Sardinia,  Italy�d. Aug. 15, 1936, Rome) Italian novelist. She wrote her first sto�  ries, influenced by the verismo (�realism�) school, at age 17. In her  approximately 40 novels, including After the Divorce (1902), Elias Por-  tolu (1903), and Ashes (1904), the ancient ways of her native Sardinia  often conflict with modem mores. Her later novel The Mother (1920) and  the posthumously published autobiographical novel Cosima (1937) were  widely admired. She received the Nobel Prize for Literature in 1926.</p><p>Eiffel Tower, an oil painting on canvas  by Robert Delaunay from 1910-11, is  on display at the Kunstmuseum, Basel,  Switzerland.

Jan. 18, 1925, Paris, France�d. Nov. 4,  1995, Paris) French antirationalist philosopher and literary critic. He  began his study of philosophy at the Sorbonne in 1944 and was appointed  to the faculty there in 1957; he later taught at the University of Lyons and  the University of Paris VIII (Vincennes). His first major publications,  David Hume (1952) and Nietzsche and Philosophy (1962), were histori�  cal studies of thinkers who emphasized the limited powers of human rea�  son. In Difference and Repetition (1968), he argued against the  devaluation of �difference� in Western metaphysics and tried to show that  difference inheres in repetition itself. A central theme of his work during  this period was the �Eleatic-Platonic bias� of Western metaphysics�i.e.,  its preference for unity over multiplicity (�the one� over �the many�) and  for sameness over difference. According to Deleuze, this bias falsifies the  nature of experience, which consists of multiplicities rather than unities.  In Anti-Oedipus (1972), the first volume of a two-volume work ( Capital�  ism and Schizophrenia ), Deleuze and the radical psychoanalyst Felix  Guattari (1930-92) attacked traditional psychoanalysis for suppressing  human desire in the service of normalization and control. The second vol�  ume, A Thousand Plateaus (1980), condemned all rationalist metaphys�  ics as �state philosophy.� Depressed by chronic illness, Deleuze  committed suicide.</p><p>Delft City (pop., 2001 est.: 96,180), southwestern Netherlands. Founded  in 1075 and chartered in 1246, it was a trade centre in the 16th-17th cen�  turies and was famous for its delftware pottery. It was the birthplace of  jurist Hugo Grotius (1583) and painter Jan Vermeer (1632). Landmarks  include a Gothic church, a Renaissance-style town hall, and a 17th-  century armory. Principal manufactures include ceramics.</p><p>delftware or delft Tin-glazed earthenware, with blue-and-white or  polychrome decoration, first made in the early 17th century at Delft, Hol�  land. Dutch potters later introduced the art of tin glazing to England along  with the name, which now applies to wares manufactured in the Nether�  lands and England. It is distinguished from faience (made in France, Ger�  many, Spain, and Scandinavia) and majolica (made in Italy).</p><p>Delhi \'de-le\ National capital territory (pop., 2001: 13,850,507), north-  central India. Bordered by the states of Uttar Pradesh and Haryana, it has  an area of 573 sq mi (1,483 sq km) and comprises the cities of Delhi  (popularly known as Old Delhi) and New Delhi (India�s capital) and adja�  cent rural areas. Delhi was the capital of a Muslim dynasty from 1206  until it was laid waste by Timur in 1398. It again was made the capital by  the Mughal Babur in 1526. Although the Mughal capital was relocated to  Agra, Delhi was beautified by Shah Jahan beginning in 1638. Pillaged by  Nadir Shah in 1739, it surrendered to the Marathas in 1771 before being  taken by the British in 1803. Delhi was a centre of the Indian Mutiny in  1857. It replaced Calcutta (now Kolkata) as the capital of British India in  1912, at which time construction began on the section of the city that  became New Delhi. The capital was moved to New Delhi in 1931, and it  became the capital of independent India in 1947. The area�s economy and  population centre mainly in Old Delhi, while government is concentrated  in New Delhi. The government is the chief employer. The territory is also  the transportation hub for north-central India.</p><p>Delhi sultanate Principal Muslim sultanate in northern India during  the 13th to the 16th centuries. Its creation owed much to the campaigns  of Muhammad of Ghur and his lieutenant Qutb al-Dln Aybak between  1175 and 1206. During the reign of Sultan Iltutmish (1211-36), a perma�  nent capital was established at Delhi and political ties with Ghur were  severed. From 1290 to 1320, under the Khaljl dynasty, the sultanate was  an imperial power. Its power was shattered by Timur�s invasion (1398�  99), but it somewhat recovered under the Lodi (Afghan) dynasty (1451�  1526). It fell again to Babur (1526), was reestablished briefly, then finally  was subsumed into Akbar�s Mughal Empire in 1556.</p><p>Delian League Vde-le-onX Confederacy of ancient Greek states led by  Athens and based on the island of Delos. Founded in 478 bc to combat  Persia, its members included Aegean states and islands; Athens supplied  commanders and assessed tributes of ships or money. It achieved a major  victory in 467-466 when its fleet drove out Persian garrisons on the  southern Anatolian coast. After 454 its leaders moved the treasury to Ath�  ens for safekeeping, used it to rebuild the city�s temples, and treated the  league as the Athenian empire. Most league members sided with Athens  in the Peloponnesian War, which diverted the league from its Persian  campaign. After defeating Athens in battle in 405, Sparta disbanded the</p><p>league in 404. Fear of Sparta helped revive the league in the early 4th  century, but it weakened as Sparta declined and was crushed by Philip II at  the Battle of Chaeronea (338).</p><p>Delibes \do-Teb\, (Clement Philibert) Leo (b.

He  studied at the Paris Conservatoire and worked as a church organist and  as accompanist and chorus master at the Paris Opera. Though he com�  posed almost 30 operas, operettas, and ballets, as well as many choral  pieces, he is remembered today for three works: the ballets Coppelia  (1870) and Sylvia (1876) and the opera Lakme (1883).</p><p>DeLillo \de-'lil-o\, Don (b. Nov. 20, 1936, New York, N.Y., U.S.) U.S.  novelist. Born to immigrant parents, DeLillo worked in advertising before  beginning to write seriously. His postmodernist works portray the unrest  and alienation of an America cosseted by material excess and stupefied  by empty mass culture and politics. Ratner�s Star (1976) attracted atten�  tion with its baroque comic sense and verbal facility. His vision later  turned darker and his characters more willful in their destructiveness and  ignorance, as in Players (1977) and White Noise (1985). Libra (1988)  portrays Lee Harvey Oswald, Underworld (1997) portrays 1950s America,  and The Body Artist (2001) centres on a woman who has to deal with the  fact of her husband�s suicide.</p><p>delinquency Criminal behaviour carried out by a juvenile. Young  males make up the bulk of the delinquent population (about 80% in the  U.S.) in all countries in which the behaviour is reported. Theories regard�  ing delinquency�s causes focus on the social and economic characteris�  tics of the offender�s family, the values communicated by the parents, and  the nature of youth and criminal subcultures, including gangs. In general,  both �push� and �pull� factors are involved. Most delinquents apparently  do not continue criminal behaviour into their adult lives but rather adjust  to societal standards. The most common punishment for delinquent  offenders is probation, whereby the delinquent is given a suspended sen�  tence and in return must live by a prescribed set of rules under the super�  vision of a probation officer. See also criminology; penology.</p><p>delirium Condition of disorientation, confused thinking, and rapid alter�  nation between mental states. The patient is restless, cannot concentrate,  and undergoes emotional changes (e.g., anxiety, apathy, euphoria), some�  times with hallucinations. Delirium usually results from a disorder affect�  ing the brain such as central nervous system infection, head trauma, or  mental disorder. In severe cases of withdrawal from alcohol, delirium tre�  mens results not from the excessive alcohol consumption alone but from  exhaustion, malnutrition (particularly lack of thiamine), and dehydration.</p><p>delirium tremens \di-Tir-e-3m-'tre-menz\ (DTs) Delirium seen in  severe cases of alcohol withdrawal (see alcoholism) complicated by  exhaustion, lack of food, and dehydration, usually preceded by physical  deterioration due to vomiting and restlessness. The whole body trembles,  sometimes with seizures, disorientation, and hallucinations. Delirium tre�  mens lasts 3-10 days, with a reported death rate of up to 20%. Halluci�  nations may develop independently of delirium tremens and may last days  to weeks.</p><p>Delius \'de-le-3s\, Frederick (Theodore Albert) (b. Jan. 29, 1862,  Bradford, Yorkshire, Eng.�d.

Bom to German parents in England, he  studied music in Leipzig and elsewhere, and in 1887 Edvard Grieg con�  vinced his parents to let him pursue a musical career. He moved to France,  eventually settling in a village near Paris. After World War I he gradually  succumbed to paralysis and blindness, the consequence of syphilis. His  works, influenced by Claude Debussy, include the operas A Village Romeo  and Juliet (1901) and Fennimore and Gerda (1910); the tone poems Brigg  Fair (1907) and On Hearing the First Cuckoo in Spring (1912); and the  choral works Appalachia (1903) and A Mass of Life (1908).</p><p>delivery See parturition</p><p>Della Robbia family \,dal-la-'r6b-y3\ Family of Italian artists active  in Florence.

Trained as a marble  sculptor, his best-known works are ten roundels of infants on the facade  of Florence�s Foundling Hospital (c. 1487). Giovanni Della Robbia  (1469-1529), the most distinguished of Andrea�s sons, took control of the  family workshop after his father�s death. His early works, notably a lavabo  in Santa Maria Novella (1497) and medallions in the Loggia of San Paolo  (1493-95), were collaborations with his father.</p><p>dell'Abbate, Niccolo See Niccolo dell�ABBATE</p><p>Delmarva Peninsula Peninsula, eastern U.S. Extending between  Chesapeake and Delaware bays, it is about 180 mi (290 km) long and up  to 70 mi (110 km) wide.

In 1962 he left his position in banking for a series  of government positions, including minister of economics and finance. As  president of the European Commission (EC) from 1985 to 1995, he  pushed through reforms and persuaded the member states to agree to the  creation of a single market in 1993, the first step toward full economic  and political integration in the European Union. When his term expired,  he was considered a leading contender for the French presidency, but he  declined to run.</p><p>Delos Vde-,las\ Greek Dhilos Vthe-.losX Island, Greece. One of the  smallest of the Cyclades, it was an ancient centre of religious, political,  and commercial life in the Aegean. It was the legendary birthplace of  Apollo and Artemis. The Delian League was established there in 478 bc,  following the Persian Wars. Made a free port by Rome in 166 bc, Delos  was a flourishing commercial post and slave market. Sacked in 88 bc dur�  ing the Mithradatic Wars, it gradually declined and was abandoned. Its  impressive ruins have been extensively excavated.</p><p>Delphi \'del-,fi\ Site of the ancient temple and oracle of Apollo in  Greece. Located on the slopes of Mount Parnassus, it was the centre of  the world in ancient Greek religion. According to legend, the oracle was  originally sacred to Gaea, and Apollo acquired it by slaying her child, the  serpent Python. From 582 bc Delphi was the site of the Pythian Games.  The oracle was consulted not only on private matters but also on affairs  of state, such as the founding of new colonies.</p><p>delphinium See larkspur</p><p>delta Low-lying plain composed of stream-borne sediments deposited  by a river at its mouth.

In recent years  geologists have discovered that much of the world�s petroleum resources  are found in ancient deltaic rocks. Deltas vary widely in size, structure,  composition, and origin, though many are triangular (the shape of the  Greek letter delta).</p><p>dema deity \'da-ms \ Any of several mythical ancestral beings of the  Marind-Anim people of southern New Guinea. In their mythology, the  killing of a divine ancestor (a dema deity) brings about the transition from  the ancestral world to the human one. In Ceramese mythology, for  example, the goddess Hainuwele grows from a coconut blossom and is  dismembered by dema men; when the pieces of her body are buried, they  become new plant species, especially tubers, the chief food of the Cer�  amese. Such myths offer explanations for the origin of agriculture as well  as for human sexuality and death.</p><p>deme \'dem\ Greek demos In ancient Greece, a country district or vil�  lage, as distinct from a pous. In the democratic reforms (508-507 bc) pro�  moted by Cleisthenes, the demes of Attica (the area around Athens) gained  a voice in local and state government. The Attic demes had their own  police powers, cults, and officials. Males aged 18 years became registered  members of the deme. Members decided deme matters and kept property  records for taxation. Each deme sent representatives to the Athenian boule  in proportion to its size. The term continued to be applied to local dis�  tricts in Hellenistic and Roman times.</p><p>dementia \di-'men-shs\ Chronic, usually progressive deterioration of  intellectual functions. Most common in the elderly, it usually begins with  short-term-memory loss once thought a normal result of aging but now</p><p>known to result from Alzheimer disease. Other common causes are Pick  disease and vascular disease. Dementia also occurs in Huntington chorea,  paresis (see paralysis), and some types of encephalitis.

He fought alongside his father at the Battle of Ipsus (301),  where Antigonus was killed, and later retook Athens (294). He became  king of Macedonia as Demetrius I Poliorcetes (�the Besieger�) after kill�  ing Alexander V (r. 297-294).

Their first venture,  The Squaw Man (1914), was the first full-length feature film produced in  Hollywood, and it established DeMille as a director. He made numerous  comedies before creating biblical spectacles such as The Ten Command�  ments (1923, remade 1956) and The King of Kings (1927). He was known  for his flamboyance and his taste for huge casts and extravagant sets.  Among his 70 other films are Samson and Delilah (1949) and The Great�  est Show on Earth (1952, Academy Award for best picture). He also hosted  the popular weekly Lux Radio Theatre (1936-45).</p><p>Deming, W(illiam) Edwards (b. Oct. 14, 1900, Sioux City, Iowa,  U.S.�d. Dec. 20, 1993, Washington, D.C.) U.S. statistician, educator, and  advocate of quality-control methods in industrial production. He received  his Ph.D. in mathematical physics from Yale University, and he subse�  quently taught at New York University for 46 years. From the 1930s he  employed statistical analysis to achieve better industrial quality control.  In 1950 he was invited to Japan to teach executives and engineers. His  ideas, which centred on tallying product defects, analyzing and address�  ing their causes, and recording the effects of the changes on subsequent  quality, were eagerly adopted there and eventually helped Japanese prod�  ucts dominate the market in much of the world. In 1951 Japan instituted  the Deming Prize, awarded to corporations that win a rigorous quality  control competition.

In a direct  democracy, the public participates in government directly (as in some  ancient Greek city-states, some New England town meetings, and some  cantons in modern Switzerland). Most democracies today are represen�  tative. The concept of representative democracy arose largely from ideas  and institutions that developed during the European Middle Ages and the  Enlightenment and in the American and French Revolutions. Democracy  has come to imply universal suffrage, competition for office, freedom of  speech and the press, and the rule of law. See also republic.</p><p>Democratic Party One of the two major political parties in the U.S.,  historically the party of labour, minorities, and progressive reformers. In  the 1790s a group of Thomas Jefferson�s supporters called themselves  �Democratic Republicans� or �Jeffersonian Republicans� to demonstrate  their belief in the principle of popular government and their opposition to  monarchism. The party adopted its present name in the 1830s, during the  presidency of Andrew Jackson. Democrats won nearly every presidential  election in the years 1836-60, but the issue of slavery split the party. The  Southern Democrats called for the protection of slavery in the new terri�  tories, whereas the Northern Democrats, led by Stephen A. Douglas, advo�  cated allowing each territory to decide by popular sovereignty whether to  accept slavery within its borders. As a result, in 1860 the new antislavery  Republican Party won its first national victory under Abraham Lincoln.  From 1861 to 19 1 3 the only Democratic president was Grover Cleveland; in  these years the party was basically conservative and agrarian-oriented, and  its members were opposed to protective tariffs. It returned to power under  Woodrow Wilson, instituting greater federal regulation of banking and  industry, but the Republicans� frank embrace of big business drew voters  amid the prosperity of the 1920s. Democrats became dominant again in  1932, electing Franklin D. Roosevelt. A coalition of urban workers, small  farmers, liberals, and others sustained Democrats in office until 1953, and  the party regained the presidency with the election of John F. Kennedy in  1960. In the 1970s and �80s the Democrats held the presidency only during  the single term of Jimmy Carter (1976-81) but retained majority control of  the House of Representatives. They regained the presidency in 1992 with  the election of Bill Clinton but lost control of both the House and the Senate  in 1994. In the presidential election of 2000, Clinton�s vice president, Al  Gore, was defeated by Republican George W. Bush. In 2004 the party�s  presidential nominee, John Kerry, was defeated by Bush, and the Demo�  crats lost seats in both houses of Congress. The modem Democratic Party  generally supports a strong federal government with powers to regulate  business and industry in the public interest; federally financed social ser�  vices and benefits for the poor, the unemployed, the aged, and other groups;  and the protection of civil rights.</p><p>Democratic Republic of the Congo See Democratic Republic of  the Congo</p><p>Democrats of the Left (DS ) formerly (1921-91) Italian Commu�  nist Party (1991-98) Democratic Party of the Left Major Italian  political party. Founded as the Partito Comunista Italiano (PCI) in 1921  by dissidents of the Italian Socialist Party�s left wing, it was outlawed with  other political parties by Benito Mussolini�s fascist government in 1926  and went underground. It participated in the Italian Resistance in World  War II. After the war it joined in coalition governments and was consis�  tently successful at the polls. In 1956, after the crimes of Joseph Stalin  were revealed, Palmiro Togliatti tried to dissociate the PCI from the Soviet  Union. Enrico Berlinguer, as party leader from 1972 to 1984, became the  leading proponent of Eurocommunism. In order to consolidate left-wing  forces and broaden its base, the party changed its name to Democratic  Party of the Left in 1991; it became one of Italy�s largest political parties  and western Europe�s largest communist party. In 1998 it renamed itself  Democrats of the Left.</p><p>Democritus \di-'ma-kr3-t9s\ (b. c. 460�d. c. 370 bc) Greek philoso�  pher. Though only a few fragments of his work survive, he was appar�  ently the first to describe invisible �atoms� as the basis of all matter. His  atoms�indestructible, indivisible, incompressible, uniform, and differing  only in size, shape, and motion�anticipated with surprising accuracy  those discovered by 20th-century scientists. For his amusement at human  foibles, he has been called �the Laughing Philosopher.� See also atomism.</p><p>demography \di-'ma-gr3-fe\ Statistical study of human populations,  especially with reference to size and density, distribution, and vital sta�  tistics. Contemporary demographic concerns include the global birth rates,  the interplay between population and economic development, the effects  of birth control, urban congestion, illegal immigration, and labour force  statistics. The basis for most demographic research lies in population cen-  suses and the registration of vital statistics.</p><p>demon or daemon \'de-man\ In religions worldwide, any of various  evil spirits that mediate between the supernatural and human realms. The  term comes from the Greek word daimon, a divine or semidivine power  that determined a person�s fate. Zoroastrianism had a hierarchy of demons,  which were in constant battle with Ahura Mazda. In Judaism it was  believed that demons inhabited desert wastes, ruins, and graves and  inflicted physical and spiritual disorders on humankind. Christianity  placed Satan or Beelzebub at the head of the ranks of demons, and Islam  designated Iblis or Satan as the leader of a host of evil jinn. Hinduism has  many demons, called asuras, who oppose the devas (gods). In Buddhism  demons are seen as tempters who prevent the achievement of nirvana.</p><p>Demosthenes \di-'mas-th3-,nez\ (b. 384 bc, Athens�d. Oct. 12, 322,  Calauria, Argolis) Athenian states�  man known as the greatest orator of  ancient Greece. According to Plu�  tarch, he was a stutterer in his youth  and improved his speech by placing  pebbles in his mouth and practicing  before a mirror. His talents were rec�  ognized early, and powerful clients  engaged him as a speechwriter.</p><p>Throughout his life he espoused  democratic principles. He roused  Athens against Philip II by his great  �Philippics,� and later against Phil�  ip�s son Alexander the Great. In so  doing he incurred the enmity of  Aeschines, who argued that Philip�s  intentions were peaceable; Demos�  thenes succeeded in having  Aeschines ostracized (330), but he  was himself later forced into exile  (324). Recalled after Alexander�s  death (323), he fled Alexander�s suc�  cessor and committed suicide.</p><p>Dempsey, Jack orig. William  Harrison Dempsey (b. June 24,</p><p>1895, Manassa, Colo., U.S.�d.

The  park�s total area is 5,000,000 acres (2,025,000 hectares).</p><p>denaturation Vde-.na-cho-'ra-shonN Biochemical process modifying a  protein�s natural configuration. It involves breaking many weak (hydro�  gen and hydrophobic) bonds (see bonding) that maintain the protein�s  highly ordered structure. This usually results in loss of biological activ�  ity (e.g., loss of an enzyme�s ability to catalyze reactions). Denaturation  can be brought about by heating; treatment with alkalis, acids, urea, or  detergents; or even vigorous shaking of the protein solution. It can be  reversed in some cases (e.g., serum albumin, hemoglobin), if conditions  favourable to the protein are restored, but not in others. The term is also  used to describe the process of rendering ethanol unfit to drink.</p><p>Dench, Dame Judi(th Olivia) (b. Dec. 9, 1934, York, Yorkshire,  Eng.) British actress. She made her stage debut in 1957 as Ophelia in  Hamlet , and Shakespearean works became her specialty. She also per�  formed in musical roles, starring in the London premiere of Cabaret in  1968. Among her many other notable credits were the 1981-84 TV series  A Fine Romance and the films 84 Charing Cross Road (1986), Mrs. Brown  (1997)�in which she starred as Queen Victoria�and Shakespeare in  Love (1998, Academy Award).</p><p>dendrochronology \ 1 den-dro-kr9-'na-l3-je\ Method of scientific dat�  ing based on the analysis of tree rings. Because the width of annular rings  varies with climatic conditions, laboratory analysis of timber core samples  allows scientists to reconstruct the conditions that existed when a tree�s  rings developed. By taking thousands of samples from different sites and  different strata within a particular region, researchers can build a com�  prehensive historical sequence that becomes a part of the scientific record.  Such master chronologies are used by archaeologists, climatologists, and  others.</p><p>Deneuve \d3-'noev\, Catherine orig. Catherine Dorleac (b. Oct.  22, 1942, Paris, France) French film actress.

In the 1950s he became a vice-premier of the Peo�  ple�s Republic of China and general secretary of the Chinese Communist  Party (CCP). He fell from favour during the Cultural Revolution but was  rehabilitated in 1973 under the sponsorship of Zhou Enlai. Though seen  as a likely successor to Zhou as premier, Deng was again ousted, this time  by the Gang of Four, when Zhou died in 1976. However, Mao Zedong  died later that year, and in the ensuing power struggle the Gang of Four  was arrested; Deng was rehabilitated for a second time. His proteges Zhao  Ziyang and Hu Yaobang became premier and CCP general secretary,  respectively. Both embraced Deng�s wide-reaching reform program,  which abandoned many orthodox communist doctrines and introduced  free-enterprise elements into the economy. Hu died in April 1989, and  Zhao was dismissed from the government after the Tiananmen Square  incident in June. Deng gradually relinquished his official posts but con�  tinued to guide China behind the scenes until his death.</p><p>dengue \'deq-ge\ or breakbone fever or dandy fever Infec�  tious, disabling mosquito-borne fever. Other symptoms include extreme  joint pain and stiffness, intense pain behind the eyes, a return of fever  after brief pause, and a characteristic rash. Dengue is caused by a virus  carried by mosquitoes of the genus Aedes, usually A. aegypti, which also  carries yellow fever. There are four strains of virus; infection with one type  does not confer immunity to the remaining three. Treatment focuses on  relieving symptoms. Patients should be isolated during the first three days,  when mosquitoes can pick up the disease from them. Prevention relies on  mosquito control.</p><p>Dengyo Daishi See Saicho</p><p>Denikin \dyi-'nye-kyin\, Anton (Ivanovich) (b. Dec. 16, 1872, near  Warsaw, Pol., Russian Empire�d. Aug. 8, 1947, Ann Arbor, Mich., U.S.)  Russian general. A professional in the imperial Russian army, he was a  lieutenant-general in World War I. After the Russian Revolution of 1917,  he and Lavr Kornilov were arrested for conspiring to overthrow the pro�  visional government. They fled south to the Don River region and  assumed command of the anti-Bolshevik (�White�) forces in the Russian  Civil War. In 1919 Denikin launched a major offensive toward Moscow,  but his forces were defeated by the Red Army at Orel. Forced to retreat,  he turned over his command to Pyotr Wrangel (1920), then fled Russia  and later settled in France.</p><p>denim Durable Twin-woven fabric with coloured (usually blue) warp  (lengthwise) and white filling (crosswise) threads, also sometimes woven  in coloured stripes. The name originated in the French serge de Nimes.  Denim is usually all-corrON, though it is sometimes made of a cotton-  synthetic mixture. Decades of use in the clothing industry, especially in  the manufacture of overalls and trousers worn for heavy labour, have  demonstrated denim�s durability, a quality that, along with its comfort,  made denim jeans extremely popular for leisure wear in the late 20th cen�  tury.</p><p>Denis, Ruth Saint See Ruth Saint Denis</p><p>Denis \do-'ne,\ English \'de-nos\, Saint or Saint Denys (d. 258?,  Paris; Western feast day October 9; Eastern feast day October 3) Patron  saint of France and traditionally the first bishop of Paris.

With a 4,500-mi  (7,300-km) coastline, Denmark has a generally temperate and often wet  climate. It has a mixed economy based on services and manufacturing. It  boasts one of the world�s oldest and most comprehensive social welfare  systems, and its standard of living is among the highest in the world.  Denmark is a constitutional monarchy. Its chief of state is the Danish  monarch, and the head of government is the prime minister. Denmark may  have been inhabited as early as about 100,000 bc. About 500 ad the first  foreign mentions of Danes as a tribe appeared. During the Viking period  the Danes expanded their territory, and by the 11th century the united  Danish kingdom included parts of what are now Sweden, England, and  Norway. Scandinavia was united under Danish rule from 1397 until 1523,  when Sweden became independent; a series of debilitating wars with  Sweden in the 17th century resulted in the Treaty of Copenhagen (1660),  which established the modern Scandinavian frontiers. Denmark gained  and lost various other territories, including Norway, in the 19th and 20th  centuries; it went through three constitutions between 1849 and 1915 and  was occupied by Nazi Germany in 1940-45. A founding member of  NATO (1949), Denmark adopted its current constitution in 1953. It  became a member of the European Economic Community in 1973 but modi�  fied its membership during the 1990s in response to some Danes� con�  cerns regarding environmental protection and social welfare. In the early  21st century, Denmark�s handling of immigrants, though a small statis�  tical minority, raised great debate.</p><p>Dennison, Aaron Lufkin (b. March 6, 1812, Freeport, Mass.,  U.S.�d. Jan. 9, 1895, Birmingham, Eng.) U.S. watch manufacturer. After  studying the methods used at the Springfield Armory, he mastered the tech�  nical difficulties of machine production of small parts, set up a factory in  Waltham, Mass., in 1850, and began to produce the first inexpensive  factory-made watches with interchangeable parts. His introduction of  machinery into the manufacture of paper boxes and other paper products  resulted in the founding of the Dennison Manufacturing Co. He is  regarded as the father of American watchmaking.</p><p>density Mass of a unit volume of a material substance. It is calculated  by dividing an object�s mass by its volume. In the International System of  Units, and depending on the units of measurement used, density can be  expressed in grams per cubic centimetre (g/cm 3 ) or kilograms per cubic</p><p>metre (kg/m 3 ). The expression �particle density� refers to the number of  particles per unit volume, not to the density of a single particle. See also  SPECIFIC GRAVITY.</p><p>density current Any current in either a liquid or a gas that is kept in  motion by the force of gravity acting on small differences in density. A  density difference can exist between two fluids or between different parts  of the same fluid. Density currents flow along ocean and lake bottoms,  because the water entering is colder, saltier, or contains more suspended  sediment and thus is denser than the surrounding water. Density currents  are a factor in water pollution, as the industrial discharge of large amounts  of polluted or heated water can generate density currents that affect neigh�  bouring human or animal communities.</p><p>density function In statistics, a function whose integral is calculated  to find probabilities associated with a continuous random variable (see  continuity, probability theory). Its graph is a curve above the horizontal axis  that defines a total area, between itself and the axis, of 1. The percentage  of this area included between any two values coincides with the prob�  ability that the outcome of an observation described by the density func�  tion falls between those values. Every random variable is associated with  a density function (e.g., a variable with a normal distribution is described  by a bell curve).</p><p>dentistry Profession concerned with the teeth and mouth. It includes  repair or removal of decayed teeth, straightening and adjustment of teeth  for proper occlusion, and design, manufacture, and fitting of false teeth  and other prosthetic devices. X-rays are used to show conditions not vis�  ible on examination. Using local anesthesia, caries in teeth are drilled to  remove diseased areas and filled with various materials. Decay that  reaches a tooth�s root risks infection of the nerve and requires root-canal  surgery. Teeth that must be extracted are replaced by crowns for single  teeth and full or partial dentures or implants for more. Dentists also edu�  cate patients on oral hygiene, examine and clean teeth, and apply fluo�  ride compounds for decay resistance.</p><p>D'Entrecasteaux V.don-tro-'kas-toX Islands Island group, Papua  New Guinea.

They have a combined  land area of 1,213 sq mi (3,142 sq km). They were named by the French  navigator Bruni d�Entrecasteaux in 1793. The chief settlement is Dobu,  located on an islet between Normanby and Fergusson.</p><p>Denver City (pop., 2000: 554,636), capital of Colorado, U.S. On the  South Platte River just east of the Rocky Mountains, its elevation of 5,280  ft (1,609 m) gives it the nickname �Mile High City.� An early stopping  place for Indians and trappers, it was settled in 1858 as St. Charles,  abruptly renamed Denver City (the �city� was eventually dropped), and  combined with the rival town of Auraria in 1860, becoming the territo�  rial capital as Denver City in 1867. The 1870s and �80s saw a silver boom  that ended in 1893, but new gold discoveries helped prevent a major  decline. Modem Denver, a transportation, industrial, and commercial hub,  has one of the nation�s largest livestock markets. It is a major centre for  winter sports, with many ski areas in the vicinity. The Denver branch of  the U.S. Mint (opened 1906) produces about 50% of U.S. coinage and is  the nation�s second largest gold depository.</p><p>deontic logic \de-'an-tik\ Branch of modal logic that studies the per�  mitted, the obligatory, and the forbidden, which are characterized as deon�  tic modalities (Greek, deontos : �of that which is binding�). It seeks to  systematize the abstract, purely conceptual relations between propositions  in this sphere, such as the following: If an act is obligatory, then its per�  formance must be permitted and its omission forbidden. In given circum�  stances, every act is such that either it or its omission is permitted. Modal  logic leaves to substantive disciplines such as ethics and law the concrete  questions of what specific acts or states of affairs are to be forbidden, per�  mitted, or the like.</p><p>deontological ethics Ethical theories that maintain that the moral  rightness or wrongness of an action depends on its intrinsic qualities, and  not (as in consequentialism) on the nature of its consequences. Deonto�  logical ethics holds that at least some acts are morally wrong in them�  selves (e.g., lying, breaking a promise, punishing the innocent, murder).  It often finds expression in slogans such as �Duty for duty�s sake.� Deon�  tological theories are often formulated in such a way that the rightness of  an action consists in its conformity to a moral rule or command, such as</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>534 I Depardieu &#x25BA; derivatives</p><p>�Do not bear false witness.� The most important exponent of deontolog-  ical ethics is Immanuel Kant.

He made his film debut in 1965 and played  minor parts until his performance in Going Places (1974) brought him a  major role in Bernardo Bertolucci�s 1900 (1976). He became French cin�  ema�s top male star in the 1980s and also made films elsewhere in Europe  and in the U.S. Noted for a screen image that combined sensitivity with  masculine strength, he delivered compelling performances in The Last  Metro (1980), The Return of Martin Guerre (1981), Jean de Florette  (1986), Matron of the Spring (1986), Cyrano de Bergerac { 1990), and Tous  les matins du monde (1992).</p><p>department store Retail establishment that sells a wide variety of  goods. These usually include ready-to-wear apparel and accessories, yard  goods and household textiles, housewares, furniture, electrical appliances,  and accessories. In addition to departments (supervised by managers and  buyers) for the various categories of goods, there are departmental divi�  sions to handle, for example, merchandising, advertising, service,  accounting, and financial strategy. The Bon Marche in Paris, which began  as a small shop in the early 19th century, is often considered the first  department store. The first U.S. department store chains�J.C. Penney and  Sears, Roebuck and Co.� date to the 1920s. See also Harrods.</p><p>dependency In international relations, a weak state dominated by or  under the jurisdiction of a more powerful state but not formally annexed  by it. Examples include American Samoa (U.S.) and Greenland (Denmark).  The dominant state may control certain of its affairs, such as defense, for�  eign relations, and internal security, and allow it autonomy in domestic  affairs such as education, health, and infrastructural development. In the  1960s and �70s the term referred to an approach to understanding third-  world development that emphasized the constraints imposed by the glo�  bal political and economic order.</p><p>depletion allowance In tax law, the deductions from gross income  allowed investors in exhaustible commodities (such as minerals, oil, or  gas) for the depletion of the deposits. The depletion allowance is intended  as an incentive to stimulate investment in this high-risk industry, though  critics argue that mineral deposits are valuable enough to justify high lev�  els of investment even without tax incentives. See also depreciation.</p><p>deposit account Either of two basic bank deposit accounts. The  demand deposit is payable on demand (see check). Theoretically, the time  deposit is payable only after a fixed interval of time; in practice, with�  drawals from most small time-deposit accounts are paid on demand.</p><p>depreciation Accounting charge for the decline in value of an asset  spread over its economic life. Depreciation includes deterioration from  use, age, and exposure to the elements, as well as decline in value caused  by obsolescence, loss of usefulness, and the availability of newer and  more efficient means of serving the same purpose. It does not include  sudden losses caused by fire, accident, or disaster. Depreciation is often  used in assessing the value of property (e.g., buildings, machinery) or  other assets of limited life (e.g., a leasehold or copyright) for tax pur�  poses. See also depletion allowance; investment credit.</p><p>depression In economics, a major downswing in the business cycle char�  acterized by sharply reduced industrial production, widespread unemploy�  ment, a serious decline or cessation of growth in construction, and great  reductions in international trade and capital movements. Unlike recessions,  which may be limited to a single country, severe depressions such as the  Great Depression encompass many nations. See also deflation; inflation.</p><p>depression Neurotic or psychotic disorder marked by sadness, inac�  tivity, difficulty in thinking and concentration, a significant increase or  decrease in appetite and time spent sleeping, feelings of dejection and  hopelessness, and sometimes suicidal tendencies. Probably the most com�  mon psychiatric complaint, depression has been described by physicians  from at least the time of Hippocrates, who called it melancholia. Its course  is extremely variable from person to person; it may be fleeting or perma�  nent, mild or severe. Depression is more common in women than in men.  The rates of incidence increase with age in men, while the peak for women  is between the ages of 35 and 45. Its causes can be both psychosocial  (e.g., the loss of a loved one) and biochemical (chiefly, reduced quanti�  ties of the monoamines norepinephrine and serotonin). Treatment is usu�  ally a combination of psychotherapy and drug therapy (see antidepressant).</p><p>A person who experiences alternating states of depression and extreme  elation is said to suffer from bipolar disorder.</p><p>Depression of T 929 See Great Depression</p><p>Depretis \da-'pre-tes\, Agostino (b. Jan. 13, 1813, Mezzana Corti,  Kingdom of Italy�d. July 29, 1887, Stradella, Italy) Italian politician. In  1848 he was elected to the first Piedmontese parliament and was reelected  thereafter until his death. After Italy was unified, he served in several  cabinet posts (1862-67). He became premier in 1876 and was the domi�  nant force in Italian politics until 1887. Among his notable achievements  were the signing of the Triple Alliance and his government policy of tras-  formismo, bringing together members of different parties in the same  cabinet.</p><p>depth charge or depth bomb Weapon used by ships or aircraft to  attack submerged submarines. Developed by the British in World War I  for use against German submarines, it consisted of a canister filled with  explosives and dropped off the stern of a ship near a submerged subma�  rine. It rarely exploded close enough to sink the submarine, but its shock  waves loosened the submarine�s joints and damaged its instruments, forc�  ing it to the surface, where naval gunfire could finish it off. Modem depth  charges can be fired as far as 2,000 yards (1,800 m) from a ship�s deck  or launched from aircraft. Atomic depth charges have a nuclear warhead  and a vastly increased killing radius.</p><p>Derain \d3-'raii\, Andre (b. June 10, 1880, Chatou, Fr.�d. Sept. 8,  1954, Garches) French painter, graphic artist, and designer. After study�  ing in Paris at the Academie Carriere and Academie Julian, he developed  his early style in association with his friends Maurice de Vlaminck and Henri  Matisse; the three were the principal exponents of Fauvism. Their land�  scapes and figure studies featured brilliant colours, broken brushstrokes,  and impulsive lines. By the 1920s, however, Derain had turned to the  Neoclassical style (see Classicism and Neoclassicism). He produced numer�  ous book illustrations and designs for stage sets, notably for Sergey Diaghi-  lev�s Ballets Russes.</p><p>Derby One of the classic English horse races (established 1780), run in  June over a 1 Vi-mi (2,400 m) course at Epsom Downs, Surrey. Many other  horse races have been named for the Derby (e.g., the Kentucky Derby), and  the term itself has come to signify a race or contest of any type.</p><p>Derby \'dar-be\, Edward (George Geoffrey Smith) Stanley,  14th earl of (b. March 29, 1799, Knowsley Park, Lancashire, Eng.�d.  Oct. 23, 1869, London) English statesman. Having entered Parliament as  a Whig in 1820, he later joined the Conservatives and became leader of  the Conservative Party (1846-68) and prime minister (1852, 1858, and  1866-68). Legislation adopted during his tenure included the removal of  Jewish discrimination in Parliament membership, the transfer of India�s  administration from the East India Company to the crown, and the Reform  Bill of 1 867. He is remembered as one of England�s greatest parliamen�  tary orators.</p><p>Derbyshire \'dar-be-,shir\ or Derby \'dar-be\ Administrative (pop.,  2001: 734,581), geographic, and historic county, central England. The  landscape varies from the moorlands of the north to the Trent lowlands  in the south. Industry ranges from tourism in the High Peak district to  mining and engineering in the eastern and southern coalfields. Apart from  gaining the rural district of Tintwistle from Cheshire, the traditional county  was unaltered by the administrative reorganization in 1974; its county seat  is Matlock.</p><p>derivative In mathematics, a fundamental concept of differential calculus  representing the instantaneous rate of change of a function. The first deriva�  tive of a function is a function whose values can be interpreted as slopes of  tangent lines to the graph of the original function at a given point. The  derivative of a derivative (known as the second derivative) describes the  rate of change of the rate of change, and can be thought of physically as  acceleration. The process of finding a derivative is called differentiation.</p><p>derivative, partial See partial derivative</p><p>derivatives In finance, contracts whose value is derived from another  asset, which can include stocks, bonds, currencies, interest rates, com�  modities, and related indexes.

Causes and patterns  vary. Contact dermatitis appears at the site of contact with an irritating  substance or allergen. Atopic dermatitis, with patches of dry skin, occurs  in infants, children, and young adults with genetic hypersensitivities  (atopy). Stasis dermatitis affects the ankles and lower legs because of  chronic poor blood flow in the veins. Seborrheic dermatitis appears as  scaly skin, most often on the scalp (dandruff) and areas rich in sebaceous  glands. Neurodermatitis is apparently caused by repeated scratching of an  itchy skin area.</p><p>dermatology Medical specialty dealing with diseases of the skin. Its  scientific basis was established in the mid-19th century by Ferdinand von  Hebra (1816-1880), whose approach was based on microscopic examina�  tion of skin lesions. Starting in the 1930s, an emphasis on biochemistry and  physiology led to more sophisticated and effective treatments. Dermatol�  ogy deals with fungal diseases, skin cancers, psoriasis, and life-threatening  skin diseases such as pemphigus, scleroderma, and lupus erythematosus.</p><p>dermestid \d9r-'mes-t3d\ (beetle) Any member of about 700 species  (family Dermestidae) of widely distributed beetles that are household pests.  Usually brown or black, some are brightly coloured or patterned, and they  vary in shape from elongated to oval. Dermestids range from 0.05 to 0.5  in. (1 to 12 mm) long and are covered with hairs or scales that easily flake  off. The wormlike larvae feed on furs, skins, feathers, horn, and hair; some  feed on cheese and dried meats or on carpets, rugs, furniture, and cloth�  ing. Two are museum pests that have destroyed collections of stuffed ani�  mals; museums and collectors must either have pestproof display shelves  or continuously apply pesticides. The larvae of carrion-feeding species  are sometimes used to clean the soft tissue attached to animal skeletons.</p><p>Dermot Macmurrough Vdar-mot-mok-'mor-oV or Diarmaid  Macmurchada Vdir-mid-mok-'mur-ko-doX (d. May 1, 1171) Irish king  of Leinster (1126-71). He faced a number of rivals in claiming the throne  of his father, Enna, and he asserted his authority by killing or blinding 17  rebel chieftains (1141). He abducted another Irish king�s wife in 1153,  beginning a bitter feud in which he was driven from Ireland (1166). He  returned with the backing of Anglo-Norman lords (including the earl of  Pembroke), and in 1170 they captured Dublin. Pembroke married Der-  mot�s daughter and became ruler of Leinster after his death. Dermot�s  appeal for Norman help in settling an internal dispute thus proved instru�  mental in the Norman conquest of Ireland.</p><p>Deroulede \da-rii-'led\ / Paul (b. Sept. 2, 1846, Paris, France�d. Jan.  30, 1914, Nice) French politician and poet. An ardent nationalist and  advocate of revenge against Germany, he helped found the revanchist  Ligue des Patriotes (League of Patriots), supported Georges Boulanger,  and campaigned against Alfred Dreyfus. After trying to overthrow the gov�  ernment in 1899, he was exiled in 1900 but allowed to return in 1905. His  patriotic poems include the collection Chants du soldat (1872).</p><p>Derrida \de-re-'da\, Jacques (b. July 15, 1930, El Biar, Alg.�d. Oct.  8, 2004, Paris, France) Algerian-born French philosopher. Derrida taught  principally at the Ecole Normale Superieure in Paris (1964-84). His cri�  tique of Western philosophy encompasses literature, linguistics, and psy�  choanalysis. His thought is based on his disapproval of the search for an  ultimate metaphysical certainty or source of meaning that has character�  ized most of Western philosophy. Instead, he offers deconstruction, which  is in part a way of reading philosophic texts intended to make explicit the  underlying metaphysical suppositions and assumptions through a close  analysis of the language that attempts to convey them. His works on  deconstructive theory and method include Speech and Phenomena (1967),  Writing and Difference (1967), and Of Grammatology (1967). Among his  other works are Psyche: Invention of the Other (1987) and Resistances  of Psychoanalysis (1996).</p><p>Derry See Londonderry (district); Londonderry (town)</p><p>Dershowitz, Alan (Morton) (b.

These mystics stressed  emotional aspects of devotion through ecstatic trances, dancing, and  whirling. Dervishes can be either resident in the community or lay mem�  bers; wandering or mendicant dervishes are called fakirs and are often  regarded as holy men who possess miraculous powers. Though viewed as  unorthodox and extreme by most Muslims, the movement has endured to  the present. See also Sufism.</p><p>Derwent Vdor-wontV River River, Tasmania, Australia. Rising in Lake  St. Clair, it flows 113 mi (182 km) southeast to enter Storm Bay through  a 3.5-mi- (5.5-km-) wide estuary. Its major upper-course tributaries have  been extensively developed for hydropower. The city of Hobart is situ�  ated on the estuary, 12 mi (19 km) from the river�s mouth. This stretch  of the river forms an excellent deepwater port and is spanned by the Tas�  man Bridge.</p><p>Derwent Water Lake, Cumbria, England. Located in the Lake District,  it is about 3 mi (5 km) long and 0.5-1.25 mi (0.8-2 km) wide, with a  maximum depth of 72 ft (22 m). The River Derwent enters its southern  end and leaves the lake�s northern end near the market town of Keswick.  Several sites on its shores are National Trust property and are frequented  by tourists. Lords Island, one of several in the lake, was once the resi�  dence of the earls of Derwentwater.</p><p>Des Moines \di-'m6in\ City (pop., 2000: 198,682), capital of Iowa, U.S.  Located at the juncture of the Raccoon and Des Moines rivers, Fort Des  Moines was established in 1843 to protect the rights of the Sauk and Fox  Indians. The area was opened to white settlers in 1845. East Des Moines  developed and by 1856 had amalgamated with Fort Des Moines to form  the present city, which became the capital in 1857. The state�s largest city,  it is a communications hub and a major manufacturing, governmental, and  publishing centre (especially for farm journals). It is the site of Drake  University (1881).</p><p>Des Moines River River, southwestern Minnesota into Iowa, U.S.  Rising near Pipestone, it flows 525 mi (845 km) southeast to join the Mis�  sissippi River near Keokuk, Iowa. Above Humboldt, Iowa, it is known as  the West Fork. From the late 1830s until the end of the American Civil  War, it was the main commercial artery for central Iowa. It was early  utilized for power, and, although none survive, 80 grain mills were built  (1840-90) along its banks.</p><p>Des Plaines \des-'planz\ River River, northeastern Illinois, U.S. Ris�  ing in southeastern Wisconsin, it flows south into Illinois past Chicago,  to join the Kankakee River after a course of 150 mi (241 km). In 1900  Chicago completed a drainage canal from the southern branch of the Chi�  cago River to the Des Plaines. It is part of the Illinois Waterway (1933),  which allows modern barge traffic to pass between the Great Lakes and the  Mississippi River.</p><p>Desai Vda-.sl, de-'slV, Anita orig. Anita Mazumdar (b.

The son of a village teacher, he joined the provincial civil ser�  vice of Bombay (now Mumbai) in 1918. He joined Mohandas K. Gan�  dhi�s struggle in 1930 and spent almost 10 years in British jails in the  1930s and �40s. In 1969 he became chairman of the opposition to Indira  Gandhi; he was detained in solitary confinement (1975-77) for his politi�  cal activities. When elections were held in 1977, he became prime min�  ister; by 1979, however, his coalition had unraveled, and he resigned.</p><p>desalination or desalting Removal of dissolved salts from seawa�  ter and from the salty waters of inland seas, highly mineralized ground-  waters, and municipal wastewaters. Desalination makes such otherwise  unusable waters fit for human consumption, irrigation, industrial applica�  tions, and other purposes. Distillation is the most widely used desalination  process; freezing and thawing, electrodialysis, and reverse osmosis are</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>536 I Descartes &#x25BA; Desmond</p><p>also used.

March 31, 1596, La Haye, Touraine,  France�d. Feb. 11, 1650, Stockholm, Swed.) French mathematician, sci�  entist, and philosopher, considered the father of modern philosophy. Edu�  cated at a Jesuit college, he joined the military in 1618 and traveled widely  for the next 10 years. In 1628 he settled in Holland, where he would  remain until 1649. Descartes�s ambition was to introduce into philosophy  the rigour and clarity of mathematics. In his Meditations on First Philoso�  phy (1641), he undertook the methodical doubt of all knowledge about  which it is possible to be deceived, including knowledge based on author�  ity, the senses, and reason, in order to arrive at something about which he  can be absolutely certain; using this point as a foundation, he then sought  to construct new and more secure justifications of his belief in the exist�  ence and immortality of the soul, the existence of God, and the reality of  an external world. This indubitable point is expressed in the dictum Cogito  ergo sum (�I think, therefore I am�). His metaphysical dualism distin�  guished radically between mind, the essence of which is thinking, and  matter, the essence of which is extension in three dimensions. Though his  metaphysics is rationalistic (see rationalism), his physics and physiology  are empiricistic (see empiricism) and mechanistic (see mechanism). In math�  ematics, he founded analytic geometry and reformed algebraic notation.</p><p>descent System of acknowledged social parentage whereby a person  may claim kinship ties with another. Descent systems vary widely. The  practical importance of descent comes from its use as a means for indi�  viduals to assert rights, duties, privileges, or status. Descent has special  influence when rights to succession, inheritance, or residence follow kin�  ship lines. One method of limiting the recognition of kinship is to empha�  size the relationship through one parent only. Such unilineal kinship  systems are of two main types�patrilineal systems, in which the rela�  tionships through the father are emphasized; and matrilineal systems, in  which maternal relationships are stressed. These systems differ radically  from cognatic systems, in which everyone has similar obligations to, and  expectations from, both paternal and maternal kin. The cognatic system  is somewhat vague and tends to characterize the more industrialized coun�  tries, in which individual rights and duties are increasingly defined insti�  tutionally or legally.</p><p>desensitization or hyposensitization Treatment to eliminate  allergic reactions (see allergy) by injecting increasing strengths of puri�  fied extracts of the substance that causes the reaction. This creates spe�  cial antibodies (blocking antibodies) in the patient�s serum that combine  with the allergen, blocking its reaction with allergic antibodies. Desensi�  tization can also be required when a penicillin-sensitive person needs to  be treated with penicillin. See also anaphylaxis, antigen.</p><p>desert Large, extremely dry area of land with fairly sparse vegetation.  It is one of the Earth�s major types of ecosystems. Areas with a mean  annual precipitation of 10 in. (250 mm) or less are generally considered  deserts. They include the high-latitude circumpolar areas as well as the</p><p>Agave shawii growing in a desert in North America.</p><p>� ROBERT AND UNDA MITCHELL</p><p>more familiar hot, arid regions of the low and mid-latitudes. Desert ter�  rain may consist of rugged mountains, high plateaus, or plains; many  occupy broad mountain-rimmed basins. Surface materials include bare  bedrock, plains of gravel and boulders, and vast tracts of shifting sand.  Wind-blown sands, commonly thought to be typical of deserts, make up  only about 2% of North American deserts, 10% of the Sahara, and 30%  of the Arabian desert.</p><p>desert varnish or patina Thin, dark red to black mineral coating  (generally iron and manganese oxides and silica) deposited on pebbles  and rocks on the surface of desert regions. As dew and soil moisture  brought to the surface by capillary action evaporate, their dissolved min�  erals are deposited on the surface. Wind abrasion removes the softer salts  and polishes the surface to a glossy finish. Both high evaporation rates  and sufficient precipitation are necessary for desert varnish to form.</p><p>desertification Spread of a desert environment into arid or semiarid  regions, caused by climatic changes, human influence, or both. Climatic  factors include periods of temporary but severe drought and long-term  climatic changes toward dryness. Human factors include artificial climatic  alteration, as through the removal of vegetation (which can lead to unnatu�  rally high erosion), excessive cultivation, and the exhaustion of water  supplies. Desertification drains an arid or semiarid land of its life�  supporting capabilities. It is characterized by a declining groundwater  table, salt accumulation in topsoil and water, a decrease in surface water,  increasing erosion, and the disappearance of native vegetation.</p><p>Desiderio da Settignano Vda-se-'der-yo-da-.sat-ten-'ya-noN (b. c.  1430, Settignano, republic of Florence�d. January 1464, Florence) Ital�  ian sculptor. Born into a family of stonemasons, he entered the Stone and  Wood Carvers� Guild of Florence in 1453. He based his style on Dona�  tello�s work of the 1430s, and his skill as a marble cutter established him  as a master of bas-relief. His delicate, sensitive, original technique was  best expressed in portrait busts of women and children. His most impor�  tant public work was the tomb of Carlo Marsuppini in the church of Santa  Croce; the tomb�s rich architectural detail makes it one of the most out�  standing of all Florentine wall monuments.</p><p>designer drug Synthetic version of a controlled narcotic substance.  Designer drugs usually are synthesized for the first time in an attempt to  create a chemical whose molecular structure differs only slightly from that  of some well-known controlled substance but whose effects are essentially  the same. Because of the difference in molecular structure, the designer  drug, unlike the controlled substance, ordinarily will not be specifically  listed as illicit by law-enforcement organizations. Many designer drugs  are manufactured in clandestine laboratories, often by amateurs; for this  reason they are sometimes more dangerous than the drugs they are  intended to replace. One of the best-known is MDMA (3,4- methylene�  dioxymethamphetamine), a variation of methamphetamine, popularly  called Ecstasy. Nonnarcotic synthetic chemical compounds designed to  interact with specific proteins and enzymes in order to combat disease  also have been called designer drugs.</p><p>desktop publishing (DTP) Use of a personal computer to perform  publishing tasks. DTP allows an individual to combine text, numerical  data, and graphic elements in a document that can be output on a printer  or a phototypesetter. A typical DTP system includes a personal computer,  a high-resolution printer, and input devices such as an optical scanner.  Text and graphic elements are commonly created or manipulated with  several separate software programs and then combined with a page-  makeup program. Powerful DTP programs offer full-featured graphics  capabilities.</p><p>desmid Vdez-modX Any of a group  of one-celled, microscopic green  algae characterized by great varia�  tion in cell shape.

March 2, 1760, Guise, France�d. April 5, 1794, Paris) French jour�  nalist influential in the French Revolution. Though a stammer had  impeded him as a lawyer, he suddenly emerged as an inspiring orator  when the Revolution began, inciting the storming of the Bastille. In his  pamphlets and newspapers he campaigned for the deposition of the king  and the establishment of a republic. Elected to the National Convention,  he joined other Montagnards in a struggle against the Girondins. Later he  and Georges Danton became leaders of a moderate faction, the Indulgents.  After attacking the Committee of Public Safety�s Reign of Terror, he was  guillotined along with other Dantonists.</p><p>Dessalines \,da-s9-Ten\, Jean-Jacques (b. c. 1758, West Africa�d.  Oct. 17, 1806, Jacmel, Haiti) Emperor of Haiti who drove out the French  in 1804. He was a slave of a black master in Saint-Domingue (Haiti) in  1791 when he joined a slave rebellion. He became a lieutenant of  Toussaint-Louverture but submitted to the French expedition that deposed  Toussaint in 1802. Napoleon�s decision to reintroduce slavery led Dessa�  lines and others to rebel, and with British help they expelled the French.  In 1804 Dessalines proclaimed the island independent under its Arawa-  kan name, Haiti, and proclaimed himself emperor the following year. He  made it illegal for whites to own property and killed thousands; he also  discriminated against mulattoes. He was killed during a mulatto revolt.</p><p>destroyer Fast naval vessel used to protect other ships. The term was  first applied to vessels built in the 1890s to protect battleships from tor�  pedo boats. By World War I destroyers were often sent ahead of the battle  fleet to scout for the enemy, beat back its destroyers with cannon fire, and  then launch torpedoes against its battleships and cruisers. When the sub�  marine became the main torpedo-launching vessel, destroyers armed with  depth charges protected convoys and battle fleets against submarine attack.  In World War II, with the addition of radar and antiaircraft guns, its escort  role included air defense. Modern destroyers are run by a crew of about  300 and equipped with surface-to-air missiles, antiship missiles, and one  or two big guns. Many carry submarine-hunting helicopters, and some  carry cruise missiles.</p><p>detached retina Separation of most layers of the retina of the eye from  the choroid, the pigmented middle layer of the eyeball. With age, small  tears can develop in the retina, and the vitreous humour inside the eye�  ball leaks through, separating the retina from the choroid. The disease ret-  rolental fibroplasia or accidents can also cause retinal detachment. It  usually develops slowly, without pain. Floating black spots and flashes of  light appear in the affected eye, and vision becomes increasingly blurred.  Without prompt treatment, it causes permanent blindness. Draining the  fluid behind the retina and applying heat, a laser beam, or extreme cold  causes scarring that seals the tears and prevents the retina from detach�  ing again.</p><p>detective story Type of popular literature dealing with the step-by-  step investigation and solution of a crime, usually murder. The first detec�  tive story was Edgar Alian Poe�s �The Murders in the Rue Morgue�  (1841). The genre soon expanded to novel length. Sherlock Holmes, the  first fictional detective to become a household name, first appeared in  Arthur Conan Doyle�s A Study in Scarlet (1887). The 1930s was the  golden age of the detective novel, exemplified by the books of Dashiell  Hammett. The introduction of mass-produced paperback books in the late  1930s made detective stories readily accessible to a wide public, and  well-known fictional detectives were created by G.K. Chesterton, Agatha  Christie, Dorothy Sayers, Raymond Chandler, Mickey Spillane, and Georges  Simenon. Among present-day mystery writers RD. James and Dick Fran�  cis rank high.</p><p>detente \da-'tant\ Period of the easing of Cold War tensions between  the U.S. and the Soviet Union from 1967 to 1979. The era was a time of  increased trade and cooperation with the Soviet Union and the signing of  the SALT treaties. Relations cooled again with the Soviet invasion of  Afghanistan.</p><p>detergent Any of various surfactants (substances that reduce surface  tension) used to dislodge dirt from soiled surfaces and retain it in suspen�</p><p>sion, allowing it to be rinsed away. The term usually refers to synthetic  substances and excludes soaps. The characteristic features of a molecule of  any detergent are a hydrophilic (water-attracting) end and a hydrophobic  (oil-attracting) end. In ionic detergents, the hydrophilic property is con�  ferred by the ionized part of the molecule. In nonionic detergents, hydro-  philicity is based on the presence of multiple hydroxyl groups or other  hydrophilic groups. Besides those used in water to clean dishes and laun�  dry, detergents that function in other solvents are used in lubricating oils,  gasolines, and dry-cleaning solvents to prevent or remove unwanted  deposits. They are also used as emulsifying agents (see emulsion).</p><p>determinant In linear algebra, a numerical value associated with a  matrix having the same number of rows as columns. It is particularly use�  ful in solving systems of (linear) equations and in the study of vectors. For  a two-by-two matrix, the determinant is the product of the upper left and  lower right terms minus the product of the lower left and upper right  terms. Determinants of larger matrices involve more complicated arith�  metic combinations of the terms and are usually solved using a calcula�  tor or computer.</p><p>determinism In philosophy, the doctrine that all events, including  human decisions, are completely determined by previously existing  causes. The traditional free will problem arises from the question, Is moral  responsibility consistent with the truth of determinism? Among those who  believe it is not consistent, some, maintaining the truth of determinism,  have concluded that no one is morally responsible for what he does (and  therefore that punishment for criminal actions is unjustified); others,  maintaining the reality of moral responsibility, have concluded that deter�  minism is false. Those who believe that moral responsibility is consistent  with determinism are known as compatibilists (see compatibilism). Pierre-  Simon Laplace is responsible for the classical formulation of determinism  in the 18th century. For Laplace, the present state of the universe is the  effect of its previous state and the cause of the state that follows it. If a  mind, at any given moment, could know all the laws and all the forces  operating in nature and the respective positions and momenta of all its  components, it could thereby know with certainty the future and the past  of every entity.</p><p>deterrence Military strategy whereby one power uses the threat of  reprisal to preclude an attack from an adversary. The term largely refers  to the basic strategy of the nuclear powers and the major alliance systems.  The premise is that each nuclear power maintains a high level of instant  and overwhelming destructive capability against any aggressor. It relies  on two basic conditions: the ability to retaliate after a surprise attack must  be perceived as credible, and retaliation must be perceived as a possibil�  ity, if not a certainty.</p><p>Detroit City (pop., 2000: 951,270), largest in Michigan, U.S. Located  on the Detroit River and founded by the French in 1701, it became a trad�  ing centre for the Great Lakes region. It surrendered to the British during  the French and Indian War, then came under U.S. control in 1796. The  capital of Michigan from 1805 to 1847, it grew as one of the country�s  shipping and flour-milling centres. In the 20th century it became the auto�  mobile capital of the world with the help of Henry Ford. The city�s indus�  trial growth attracted migrants, at first Europeans and later Southern  blacks, who by 1990 made up three-fourths of the population. The decline  in the area�s automotive industry brought economic hardship in the late  20th century.

It flows south for 32 mi (51 km) past Detroit and Wind�  sor, Ont., where a bridge and tunnel connect the two cities. The largest  islands in the river are Belle Isle (a city park of Detroit) and Grosse lie  (a residential area with an airport), both in Michigan, and Fighting Island  in Ontario. The river is heavily used by both pleasure craft and Great Lakes  shipping.</p><p>deus ex machina Vda-os-.eks-'ma-ki-no, 'da-os-.eks-mo-'she-noN  Stage device in Greek and Roman drama in which a god appeared in the  sky by means of a crane (Greek, mechane ) to resolve the plot of a play.  Plays by Sophocles and particularly Euripides sometimes require the device.  The term now denotes something that appears suddenly and unexpectedly  and provides an artificial solution to an apparently insoluble difficulty.</p><p>deuterium \du-'tir-e-9m\ or heavy hydrogen Isotope of hydrogen,  chemical symbol 2 H or D, atomic number 1 (but atomic weight approxi-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>538 I deuterium oxide &#x25BA; Devrient family</p><p>mately 2). Harold C. Urey won a Nobel Prize for its discovery and iso�  lation. Its nucleus contains one proton and one neutron. A stable substance  found in naturally occurring hydrogen compounds to the extent of about  0.015%, deuterium can be purified by distillation of hydrogen or by elec�  trolysis of water. It enters into all the same chemical reactions as ordinary  hydrogen; it forms D 2 and HD, analogous to molecular hydrogen (H 2 ),  and D 2 0 (heavy water), analogous to ordinary water (H 2 0). Nuclear fusion  of deuterium atoms or of deuterium and tritium at high temperatures  releases enormous amounts of energy. Such reactions have been used in  nuclear weapons and experimental power reactors. Deuterium is useful as  a tracer in research into reaction mechanisms and biochemical pathways.</p><p>deuterium oxide See heavy water</p><p>Deuteronomic Reform Vdti-to-ro-'na-mikA Religious reformation in  Judah during the reign of King Josiah (c. 640-609 bc). As Assyria�s hold  on Israel weakened, Josiah waged a campaign against foreign cults and  had their altars and idols removed from the Temple. He called for a return  to the observance of Mosaic Law, based on the book of the Law discov�  ered in the Temple of Jerusalem (c. 622 bc), believed to be the same book  as the law code in the Book of Deuteronomy. Rural sanctuaries and fer�  tility cults were destroyed and the worship of Yahweh (the God of Israel)  was centralized at Jerusalem.</p><p>deva Vda-vo, 'de-vo\ (Sanskrit: �divine�) In the Vedic religion of India,  one of many divine powers, roughly divided into sky, air, and earth divini�  ties. During the Vedic period, the gods were divided into two classes, the  devas and the asuras. In India the devas gradually came to be more pow�  erful, and the asuras came to be thought of as demons. In the monothe�  istic systems that emerged by the late Vedic period, the devas were  subordinate to one supreme being.</p><p>devaluation Reduction in the exchange value of a country�s monetary  unit in terms of gold, silver, or foreign currency. By decreasing the price  of the home country�s exports abroad and increasing the price of imports  in the home country, devaluation encourages the home country�s export  sales and discourages expenditures on imports, thus improving its balance  OF PAYMENTS.</p><p>devaraja N.da-vo-'ra-jaN In ancient Cambodia, the cult of the �god-  king,� established early in the 9th century by Jayavarman II (c. 770-850),  founder of the Khmer empire. The cult taught that the king was a mani�  festation of the god Shiva. For centuries it provided Khmer kings with the  religious basis of their royal authority.</p><p>development, biological Gradual changes in size, shape, and func�  tion during an organism�s life that translate its genetic potentials (geno�  type) into functioning mature systems (phenotype). It includes growth but  not repetitive chemical changes (metabolism) or changes over more than  one lifetime (evolution). DNA directs the development of a fertilized egg  so that cells become specialized structures that carry out specific func�  tions. In humans, development progresses through the embryo and fetus  stages before birth and continues during childhood. Other mammals fol�  low a similar course. Amphibians and insects go through distinctive stages  that are quite different. In plants, the basic pattern is determined by the  arrangement of lateral buds around a central growing stem. Different rates  of growth of the plant�s component elements then determine its shape and  that of various parts. In both animals and plants, growth is greatly influ�  enced by hormones; factors within individual cells probably also play a  role.</p><p>development bank National or regional financial institution  designed to provide medium- and long-term capital for productive invest�  ment. Such investment is usually accompanied by technical assistance.  Some development banks are government-owned and -operated, while  others are private. Many have been established under the auspices of the  World Bank. Among the largest are the Inter-American Development  Bank, the Asian Development Bank, and the African Development Bank.</p><p>developmental psychology Branch of psychology concerned with  changes in cognitive, motivational, psychophysiological, and social func�  tioning that occur throughout the human life span. In the late 19th and  early 20th centuries, developmental psychologists were concerned prima�  rily with child psychology. In the 1950s they became interested in the rela�  tionship between child rearing and adult personality, as well as in  examining adolescence in its own right. By the late 20th century they had  become interested in all aspects of psychological development and change  over the entire life span.</p><p>Devi \'da-ve\ Term used to designate a goddess in Hinduism. It is some�  times used as an honorific title for women, and it may also refer to local  female divinities throughout India. In the 5th-6th century, Hindu texts first  began to identify Devi as the Great Goddess and the embodiment of mat�  ter, energy, and illusion. She is represented in a variety of aspects, both  good and evil, including the beautiful but menacing Durga, the destruc�  tive Kali, and the sexually powerful Shakti (see shakti).</p><p>devil Spirit or power of evil. Though sometimes used to refer to demons,  the term more often designates the prince of evil spirits. In the Bible the  Devil is known as Satan, Beelzebub, and Lucifer. In Judaism, Satan emerges  as subservient to God and as an adversary and accuser of Job and other  humans. In postbiblical traditions he emerges as the tempter of human�  kind and is responsible for all the sins in the Bible. Christian theology  holds that his main task is to tempt humans to reject the way of life and  redemption in favour of sin and death. In the Qur�an the Devil is frequently  associated with IblTs; he tempts the unfaithful but not the true believer. In  Hinduism there is no principal devil, although there are a variety of demons  or devilish beings. Buddhists also recognize the existence of many demons,  and Mara, the Buddha�s opponent and tempter, is sometimes identified as  a specific devil.</p><p>devil ray See manta ray  devilfish See manta ray</p><p>Devils Island French Tie du Diable \ l el-due- l dyabl�\ Rocky islet off  the Atlantic coast of French Guiana. The smallest of the three lies du Salut,  it is a narrow strip of land 3,900 ft (1,200 m) long and 1,320 ft (400 m)  wide. Part of a penal settlement since 1852, it housed the convicts� leper  colony until the islands were made a maximum-security area. It shared  the notoriety for cruelty of the mainland French Guiana penal colony.  Spies and political prisoners, including Alfred Dreyfus, were held there.  The island�s use as a penal colony was phased out by the early 1950s.</p><p>Devils Tower National Monument National preserve, northeast�  ern Wyoming, U.S. The first U.S. national monument, it was established  in 1906 near the Belle Fourche River. It includes 1,347 acres (545 hect�  ares) and features a natural rock tower, the remnant of a volcanic intru�  sion now exposed by erosion. The tower has a flat top and is 865 ft (264  m) high.</p><p>Devolution, War of (1667-68) Conflict between France and Spain  over possession of the Spanish Netherlands. Louis XIV began the war on the  pretext that the custom of devolution, whereby daughters of a first mar�  riage were preferred to sons of subsequent marriages regarding property  inheritance, should apply to sovereign territories also. That would mean  that his wife, Marie-Therese (1638-1683), should succeed her father, Philip  IV, in the Spanish Netherlands. The French army advanced into Flanders  in May 1667 and easily secured its objectives. A peace was reached at  Aix-la-Chapelle, whereby France gave up Franche-Comte but retained  conquered towns in Flanders.</p><p>Devon \'de-von\ Administrative (pop., 2001: 704,499), geographic, and  historic county, southwestern England.

Its area includes the moor�  lands of Dartmoor, inhabited from prehistoric times and now a popular  tourist area. Livestock-based agriculture is the main industry; Devonshire  clotted cream is still produced.</p><p>Devonian \di-'vo-ne-3n\ Period Interval of geologic time from 417  to 354 million years ago; it was the fourth period of the Paleozoic Era.  During the Devonian, a giant continent was situated in the Southern Hemi�  sphere (see Gondwana), and other landmasses were located in the equa�  torial regions. Siberia was separated from Europe by a broad ocean, and  North America and Europe were joined. Many types of primitive marine  and freshwater fish appeared and proliferated, and the period is sometimes  referred to as the Age of Fishes.

Karl�s brother Eduard (1801-77)  began his career as an opera singer, then worked as an actor and stage  director in Dresden (1844-52) and Karlsruhe (1852-70), where he  directed German classics and made new translations of Shakespeare�s  plays. Karl�s other brother, Emil (1803-72), made his stage debut in 1821  and acted with the Dresden court theatre (1831-68); his greatest successes  were as Hamlet and as Goethe�s Tasso. Eduard�s son Otto (1838-94) acted  in various companies, then became a director in Karlsruhe and other Ger�  man cities. In Weimar he produced his own version of Goethe�s Faust  (1876); he also wrote several tragedies. Karl�s son Max (1857-1929)  made his debut in Dresden in 1878 and in 1882 joined the famed Vienna  Burgtheater.</p><p>dew Deposit of water droplets formed at night by the condensation of  water vapour from the air onto the surfaces of exposed objects. Dew forms  on clear nights, when exposed surfaces lose heat by radiation and are thus  usually colder than the air.

U.S. philosopher and educator who was one of the  founders of pragmatism, a pioneer in functional psychology, and a leader  of the Progressive movement in U.S. education. He received a Ph.D.  (1884) from Johns Hopkins University and taught 10 years at the Uni�  versity of Michigan before moving to the University of Chicago. Influ�  enced by G. Stanley Hall and William James, he developed an  instrumentalist theory of knowledge that conceived of ideas as tools for  the solution of problems encountered in the environment. Believing the  experimental methods of modern science provided the most promising  approach to social and ethical problems, he applied this view to studies  of democracy and liberalism. He asserted that democracy provided citi�  zens with the opportunity for maximum experimentation and personal  growth. His writings on education, notably The School and Society (1899)  and The Child and the Curriculum (1902), emphasized the interests of the  child and the use of the classroom to cultivate the interplay between  thought and experience. At Chicago he created laboratory schools to test</p><p>his theories. His work in psychology focused on the total organism in its  efforts to adjust to the environment. In 1904 Dewey joined the Columbia  University faculty. In 1925 he published his magnum opus. Experience  and Nature.</p><p>Dewey, Melvil(le Louis Kossuth) (b.

In 1876 he published A Classification and Subject Index  for Cataloguing and Arranging the Books and Pamphlets of a Library,  in which he outlined the Dewey Decimal Cassification system. He was one  of the founders of the American Library Association and of Library Jour�  nal (both 1876). He set up the School of Library Economy, the first U.S.  institution for training librarians. He also reorganized the N.Y. State  Library (1889-1906) and established the system of traveling libraries and  picture collections.

His successful prosecution of organized-crime  figures won him three terms as governor of New York (1943-55), during  which he pursued policies of political and fiscal moderation. He received  the Republican presidential nomination in 1944 but was soundly defeated  by Franklin D. Roosevelt; nominated again in 1948, he was widely pre�  dicted to defeat the incumbent, Harry S. Truman, but Truman retained the  vote of farmers and labour to prevail. Dewey retired from politics in 1955  but continued to advise Republican administrations.</p><p>Dewey Decimal Classification or Dewey Decimal System</p><p>System for organizing the contents of a library based on the division of  all knowledge into 10 groups. Each group is assigned 100 numbers. Sub�  divisions eventually extend into decimal numbers; for example, the his�  tory of England is placed at 942, the history of the Stuart period at 942.06,  and the history of the English Commonwealth at 942.063. The system  was first formulated in 1873 by Melvil Dewey. Many libraries add a book  number created from the Cutter, or Cutter-Sanborn, Tables, which further  specify author and genre.

Insulin, synthesized in the islets of  Langerhans (see Langerhans, islets of), is necessary to metabolize glucose.  In diabetes, blood sugar levels increase (hyperglycemia). Excess sugar is  excreted in the urine (glycosuria). Symptoms include increased urine out�  put, thirst, weight loss, and weakness. Type 1, or insulin-dependent dia�  betes mellitus (IDDM), an autoimmune disease in which no insulin is  produced, must be treated by insulin injections. Type 2, or non-insulin-  dependent diabetes mellitus (NIDDM), in which tissues do not respond  to insulin, is linked to heredity and obesity and may be controlled by diet;  it accounts for 90% of all cases, many of which go undiagnosed for years.  Untreated diabetes leads to accumulation of ketones in the blood, followed  by acidosis (high blood acid content) with nausea and vomiting and then  coma. Careful attention to content and timing of meals, with periodic</p><p>checking of blood sugar, may manage diabetes. If not, injected or oral  insulin is necessary. Complications, including heart disease, diabetic ret�  inopathy (a leading cause of blindness), kidney disease, and nerve disor�  ders, especially in the legs and feet, account for most deaths. Degree of  blood-sugar control does not always correlate with progression of com�  plications.

Its central tenet, borrowed from Hegelianism, is that all his�  torical growth, change, and development results from the struggle of  opposites. (In philosophical terms, a thesis is opposed by its antithesis,  which results in a synthesis.) Specifically, it is the class struggle�the  struggle between the capitalist and landowning classes, on the one hand,  and the proletariat and peasantry, on the other�that creates the dynamic  of history. The laws of historical dialectics are seen to be so powerful that  individual leaders are of little historical consequence. Originally con�  ceived as operating primarily in the social, economic, and political realm,  the principle was extended in the 20th century to the scientific realm as  well, with major effects on Soviet science. Marx and Engels stated their  philosophical views mainly in the course of polemics and brief historical  studies; there is no systematic exposition of dialectical materialism.</p><p>dialysis \dl-'a-b-s9s\ In chemistry, separation of suspended colloidal  (see colloid) particles from dissolved ions or small molecules via their  unequal rates of diffusion through pores of semipermeable membranes (e.g.,  parchment, collodion, cellophane). A slow process, dialysis may be accel�  erated by heating or by applying an electric field if the particles are charged.</p><p>dialysis \dl-'a-b-s3s\ or hemodialysis \ I he-mo-dI-'a-b-s9s\ Process  of removing blood from a patient with kidney failure, purifying it with a  hemodialyzer (artificial kidney), and returning it to the bloodstream. Many  substances (including urea and inorganic salts) in the blood pass through  a porous membrane in the machine into a sterile solution; particles such  as blood cells and proteins are too large to pass. This process controls the  acid-base balance of the blood and its content of water and dissolved  materials.</p><p>diamagnetism Kind of magnetism characteristic of materials that line  up at right angles to a nonuniform magnetic field and that partly expel from  their interior the magnetic field in which they are placed. In most mate�  rials, the magnetic fields of the electrons balance each other and add up  to zero. However, when placed in an external magnetic field, the inter�  action of this field with the electrons induces an internal field in the oppo�  site direction. The substance can then be weakly repelled by magnetic  poles. Examples of diamagnetic substances include bismuth, antimony,  SODIUM CHLORIDE, GOLD, and MERCURY.</p><p>diamond Mineral composed of pure carbon, the hardest naturally  occurring substance known and a valuable gemstone. Diamonds are  formed deep in the Earth by tremendous pressures and temperatures over  long periods of time. In the crystal structure of diamond, each carbon atom  is linked to four other, equidistant, carbon atoms. This tight crystal struc�  ture results in properties that are very different from those of graphite, the  other common form of pure carbon. Diamonds vary from colourless to  black and may be transparent, translucent, or opaque. Most gem diamonds  are transparent and colourless or nearly so. Colourless or pale blue stones  are most valued, but most gem diamonds are tinged with yellow. Because  of their extreme hardness, diamonds have important industrial applica�  tions. Most industrial diamonds are gray or brown and are translucent or  opaque. In the symbolism of gemstones, the diamond represents steadfast  love and is the birthstone for April.</p><p>diamond cutting Branch of lapidary art involving the five basic steps  in fashioning a diamond: marking, cleaving, sawing, girdling, and face�  ting. The most popular style is the brilliant cut, a round stone with 58  facets; a round diamond with only 18 facets is known as a single cut. Any  other style is known as a fancy cut.

Daughter of Vis�  count Althorp (later Earl Spencer), she was a kindergarten teacher at the  time of her engagement to Charles, whom she married on July 29, 1981,  in a globally televised ceremony. They had two sons. Princes William  (1982) and Henry (1984). Her beauty and unprecedented popularity as a  member of the royal family attracted intense press attention, and she  became one of the most photographed women in the world. The marriage  gradually broke down; Charles and Diana separated in 1992 and were  divorced in 1996. She remained highly visible and continued her activi�  ties on behalf of numerous charities. In 1997 she was killed in a car crash  in Paris, along with her companion, Emad Mohamed (Dodi) al-Fayed  (1955-97), and their driver.

Diane came to the French court as a lady-in-waiting, where  Henry, 20 years her junior, fell violently in love with her. After the death of  her husband, Diane became Henry�s mistress from c. 1536. Throughout his  reign (1547-59) she held court as queen of France in all but name, while the  real queen, Catherine de Medicis, was forced to live in comparative obscu�  rity.

Mild cases of  diarrhea are treated with bismuth subsalicylate (trade name Pepto-  Bismol); extreme cases are treated with fluid and electrolyte replacement  while the underlying disease passes. Traveler�s diarrhea affects up to half  of people who travel to developing countries. Its prevention includes tak�  ing bismuth subsalicylate tablets, drinking only bottled or canned bever�  ages, and eating only peeled fruits, canned products, and restaurant food  that is well-cooked. Severe cases require antibiotics. In cases of severe  malnutrition, diarrhea is potentially lethal, and it is responsible for hun�  dreds of thousands of deaths annually in underdeveloped countries.</p><p>diary or journal Record of events, transactions, or observations kept  daily or at frequent intervals; especially a daily record of personal activi�  ties, reflections, or feelings. Written primarily for the writer�s use alone,  the personal diary usually offers a frankness not found in writing done for  publication. The diary form, which began to flower in the late Renais�  sance, is important as a record of social and political history. The most  famous diary in English is that of Samuel Pepys. Other notable journals  include those of John Evelyn, Jonathan Swift, Fanny Burney, James Boswell,  Andre Gide, and Virginia Woolf.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>542 I Dias &#x25BA; Dickens</p><p>Dias \'de-3sh\, Bartolomeu or Bartholomew Diaz \'de-as\ (b. c.  1450�d.

The term also carries religious, philosophical, politi�  cal, and eschatological connotations, inasmuch as the Jews perceive a  special relationship between the land of Israel and themselves. Interpre�  tations of this relationship range from the messianic hope of traditional  Judaism for the eventual �ingathering of the exiles� to the view of Reform  Judaism that the dispersal of the Jews was providentially arranged by God  to foster monotheism throughout the world. Historically, Diaspora Jews  outnumbered the Jews in Palestine even before the destruction of Jeru�  salem in ad 70. Thereafter, the chief centres of Judaism shifted from coun�  try to country (e.g., Babylonia, Persia, Spain, France, Germany, Poland,  Russia, and the U.S.), and Jewish communities gradually adopted distinc�  tive languages, rituals, and cultures, some submerging themselves in non-  Jewish environments more completely than others. While some lived in  peace, others became victims of violent anti-Semitism. While the vast  majority of Orthodox Jews have supported Zionism, some Orthodox Jews  go so far as to oppose the modem State of Israel on the grounds that it is  a godless and secular state defying God�s will to send his messiah at the  time he has preordained.</p><p>diastrophism Vdl-'as-tro-.fi-zonA or tectonism Large-scale deforma�  tion of the Earth�s crust by natural processes, which leads to the forma�  tion of continents and ocean basins, mountain systems and rift valleys,  and other features by mechanisms such as lithospheric plate movement  (see plate tectonics), volcanic loading, or folding.

When peace was  restored to Mexico under Benito  JuArez, Diaz resigned his command,  but he soon became dissatisfied with  the government. After leading two  revolts, he was elected president in  1877. He succeeded in bolstering the  export economy through foreign  investment, while leading in the  spirit of a caudillo, suppressing oppo�  sition, rigging elections, and using  patronage to win the cooperation of  various groups.

With his father in debtors� prison, he was withdrawn from school and  forced to work in a factory. This deeply affected the sensitive boy. Though  he returned to school at 13, his formal education ended at 15. As a young  man, he worked as a reporter. His fiction career began with short pieces  reprinted as Sketches by �Boz� (1836). He exhibited a great ability to spin  a story in an entertaining manner and this quality, combined with the seri�  alization of his comic novel The Pickwick Papers (1837), made him the  most popular English author of his time. The serialization of such works  as Oliver Twist (1838) and The Old Curiosity Shop (1841) followed. After  a trip to America, he wrote A Christmas Carol (1843) in a few weeks.  With Dombey and Son (1848), his novels began to express a heightened  uneasiness about the evils of Victorian industrial society, which intensi�  fied in the semiautobiographical David Copperfield (1850), as well as in  Bleak House (1853), Little Dorrit (1857), Great Expectations (1861), and  others. A Tale of Two Cities (1859) appeared in the period when he  achieved great popularity for his public readings. Dickens�s works are  characterized by an encyclopaedic knowledge of London, pathos, a vein  of the macabre, a pervasive spirit of benevolence and geniality, inex�  haustible powers of character creation, an acute ear for characteristic  speech, and a highly individual and inventive prose style.</p><p>Dickey, James (Lafayette) (b.

His poetry�published in such volumes  as Into the Stone (1960), Drowning with Others (1962), Helmets (1964),  Buckdancer�s Choice (1965), and The Zodiac (1976)�combines themes  of nature mysticism, religion, and history.

Granddaughter of the  cofounder of Amherst College and daughter of a respected lawyer and  one-term congressman, Dickinson was educated at Amherst (Mass.) Acad�  emy and Mount Holyoke Female Seminary. She subsequently spent vir�  tually all her life, increasingly reclusive, in her family home in Amherst.  She began writing in the 1850s; by 1860 she was boldly experimenting  with language and prosody, striving for vivid, exact words and epigram�  matic concision while adhering to the basic quatrains and metres of the  Protestant hymn. The subjects of her deceptively simple lyrics, whose  depth and intensity contrast with the apparent quiet of her life, include  love, death, and nature. Her numerous letters are sometimes equal in art�  istry to her poems. By 1870 she was dressing only in white and declin�  ing to see most visitors. Of her 1,775 poems, only seven were published  during her lifetime. After posthumous publications (some rather inaccu�  rate), her reputation and readership grew. Her complete works were pub�  lished in 1955, and she has since become universally regarded as one of  the greatest American poets.</p><p>Dickinson, John (b. Nov. 8, 1732, Talbot county, Md.�d.

He won fame in 1767-68 as the author  of the Letters from a Farmer in Pennsylvania, to the Inhabitants of the  British Colonies, which influenced opinion against the Townshend Acts.  A delegate to the Continental Congress, he helped draft the Articles of  Confederation. Hoping for conciliation with the British, he voted against  the Declaration of Independence.

Nominated in times of crisis by a consul, recommended by  the Senate, and confirmed by the Comitia Curiata, the dictator�s term was  six months or the duration of the crisis, and he had authority over all other  magistrates. By 300 bc his powers were limited; no dictators were cho�  sen after 202. The dictatorships of Sulla and Julius Caesar were a new  form with almost unlimited powers. Caesar became dictator for life just  before his assassination; afterward the office was abolished.</p><p>dictatorship Form of government in which one person or an oligarchy  possesses absolute power without effective constitutional checks. With  constitutional democracy, it is one of the two chief forms of government  in use today. Modern dictators usually use force or fraud to gain power</p><p>and then keep it through intimidation, terror, suppression of civil liber�  ties, and control of the mass media. In 20th-century Latin America, nation�  alist leaders often achieved power through the military and attempted  either to maintain the privileged elite or to institute far-reaching social  reform, depending on their class sympathies. In Europe�s communist and  fascist dictatorships, a charismatic leader of a mass party used an official  ideology to maintain his regime, and terror and propaganda to suppress  opposition. In postcolonial Africa and Asia, dictators have often retained  power by establishing one-party rule after a military takeover.</p><p>dictionary Reference work that lists words, usually in alphabetical  order, and gives their meanings and often other information such as pro�  nunciations, etymologies, and variant spellings. The earliest dictionaries,  such as those created by Greeks of the 1 st century ad, emphasized changes  that had occurred in the meanings of words over time. The close juxta�  position of languages in Europe led to the appearance, from the early  Middle Ages on, of many bilingual and multilingual dictionaries. The  movement to produce an English dictionary was partly prompted by a  desire for wider literacy, so that common people could read Scripture, and  partly by a frustration that no regularity in spelling existed in the lan�  guage. The first purely English dictionary was Robert Cawdrey�s A Table  Alphabetical (1604), treating some 3,000 words. In 1746-47 Samuel  Johnson undertook the most ambitious English dictionary to that time, a  list of 43,500 words. Noah Webster�s dictionary of Americanisms in the  early 19th century sprang from a recognition of the changes and varia�  tions within language. The immense Oxford English Dictionary was begun  in the late 19th century. Today there are various levels of dictionaries,  general-purpose dictionaries being most common.

In the 1890s he invented the internal-combustion engine that bears his  name, producing a series of increasingly successful models of the diesel  engine that culminated in his demonstration in 1897 of a 25-horsepower,  four-stroke, single vertical cylinder compression engine.</p><p>diesel engine Internal-combustion engine in which air is compressed to  a temperature sufficiently high to ignite fuel injected into the cylinder,  where combustion and expansion activate a piston (see piston and cylin�  der). It converts the chemical energy stored in the fuel into mechanical  energy, which can be used to power large trucks, locomotives, ships, small  electric-power generators, and some automobiles. The diesel engine dif�  fers from other internal-combustion engines (such as gasoline engines) in  that it has no ignition system and so is often called a compression-ignition  engine. Diesel fuel is low-grade and comparatively unrefined. Compared  to other internal-combustion engines, diesel engines are more reliable, last  longer, and cost less to operate, but they also produce more air pollution,  noise, and vibration.</p><p>Diet Japanese national legislature.

Along  with the goddess Laima, he determined the course of the world and human  destiny. He was pictured as a Baltic king who lived on a farmstead in the  heavens, occasionally descending to earth on horseback or in a chariot to  serve as the protector of farmers and their crops. His two sons were the  morning and evening stars. In modern Baltic, dievs refers to the Chris�  tian God.</p><p>Diez \'dets\, Friedrich Christian (b. March 15, 1794, Giessen, Hesse-  Darmstadt�d.

He began his career as a scholar of  medieval Provencal poetry and taught literature at the University of Bonn  from 1823 to the end of his life. Diez applied the methodology of com�  parative linguistics pioneered by Jacob Grimm and Franz Bopp to the  Romance languages. In his Grammar of the Romance Languages (1836�  44) and Etymological Dictionary of the Romance Languages (1853), he  demonstrated the relationship of �Vulgar� or Spoken Latin to Classical  Latin and the evolution of Romance languages from Spoken Latin into  their modern forms.</p><p>difference equation Equation involving differences between succes�  sive values of a function of a discrete variable (i.e., one defined for a  sequence of values that differ by the same amount, usually 1). A function  of such a variable is a rule for assigning values in sequence to it. For  example,/(x + 1) = x/(x) is a difference equation. Methods developed for  solving such equations have much in common with methods for solving  linear differential equations, which difference equations are often used to  approximate.</p><p>differential In calculus, an expression based on the derivative of a func�  tion, useful for approximating certain values of the function. The differ�  ential of an independent variable x, written Ax, is an infinitesimal change  in its value. The corresponding differential of its dependent variable y is  given by Ay = /(x + Ax) - /(x). Because the derivative of the function  /(x), f'(x), is equal to the ratio as Ax approaches zero (see limit), for</p><p>small values of Ax, Ay =/'(x)Ax. This formula often enables a quick and  fairly accurate approximation to be made for what otherwise would be a  tedious calculation.</p><p>differential calculus Branch of mathematical analysis, devised by  Isaac Newton and G.W. Leibniz, and concerned with the problem of find�  ing the rate of change of a function with respect to the variable on which  it depends. Thus it involves calculating derivatives and using them to solve  problems involving nonconstant rates of change. Typical applications  include finding maximum and minimum values of functions in order to solve  practical problems in optimization.</p><p>differential equation Mathematical statement that contains one or  more derivatives. It states a relationship involving the rates of change of  continuously changing quantities modeled by functions. Differential equa�  tions are very common in physics, engineering, and all fields involving  quantitative study of change. They are used whenever a rate of change is  known but the process giving rise to it is not. The solution of a differen�  tial equation is generally a function whose derivatives satisfy the equa�  tion. Differential equations are classified into several broad categories.  The most important are ordinary differential equations (ODEs), in which  change depends on a single variable, and partial differential equations  (PDEs), in which change depends on several valuables.

On  a straight road the wheels rotate at the same speed; when turning a cor�  ner the outside wheel has farther to go and would turn faster than the  inner wheel if unrestrained. The automobile differential was invented in  1827; originally used on steam-driven vehicles, it was well known when  internal-combustion engines finally appeared.</p><p>differential geometry Field of mathematics in which methods of cal�  culus are applied to the local geometry of curves and surfaces (i.e., to a  small portion of a surface or curve around a point). A simple example is  finding the tangent line on a two-dimensional curve at a given point. Similar  operations may be extended to calculate the curvature and length of a curve  and to analogous properties of surfaces in any number of dimensions.</p><p>differential operator In mathematics, any combination of derivatives  applied to a function. It takes the form of a polynomial of derivatives, such  as D 2 XX - D 2 xy � D 2 yx , where D 2 is a second derivative and the subscripts  indicate partial derivatives. Special differential operators include the gra�  dient, divergence, curl, and Laplace operator (see Laplace's equation). Dif�  ferential operators provide a generalized way to look at differentiation as  a whole, as well as a framework for discussion of the theory of differen�  tial EQUATIONS.</p><p>differentiation Mathematical process of finding the derivative of a  function. Defined abstractly as a process involving limits, in practice it may  be done using algebraic manipulations that rely on three basic formulas  and four rules of operation. The formulas are: (1) the derivative of x" is  nxP ~ 1 , (2) the derivative of sin x is cos x, and (3) the derivative of the  exponential function e x is itself. The rules are: (1) ( af+ bg)' = af + bg\  (2) (fg)' =fg' + gf, (3) (fig)' = (gf -fg')/g 2 , and (4) (f(g))'=f\g)g\  where a and b are constants,/and g are functions, and a prime (') indi�  cates the derivative. The last formula is called the chain rule. The deri�  vation and exploration of these formulas and rules is the subject of  DIFFERENTIAL CALCULUS.

In the mouth, food is chewed, mixed with saliva,  which begins to break down starches, and kneaded by the tongue into a  ball for swallowing. Peristalsis propels it through the esophagus and the  rest of the alimentary canal. In the stomach, food mixes with acid and  enzymes, which further break it down. The mixture, called chyme, enters  the duodenum, the first part of the small intestine. Bile from the liver breaks  up fat globules. Enzymes from the pancreas and intestinal glands act on  specific molecules, breaking carbohydrates down into simple sugars, pro�  teins into amino acids, and fats into glycerol and fatty acids. These prod�  ucts are absorbed by the bloodstream. Indigestible substances, such as  fibre, pass into the large intestine, where water and ions are reabsorbed  and feces held for excretion.

Food taken in by the mouth is guided  by the tongue as it is sheared and ground by the teeth. The bolus of chewed food is  moistened and lubricated with saliva secreted by the salivary glands. Enzymes in  the saliva begin the breakdown of starches. The epiglottis, a flap of tissue, prevents  food from the pharynx from entering the larynx during swallowing. Muscles in the  esophagus wall contract in waves to move the food to the stomach. Gastric juices  secreted by the stomach contain a mixture of substances (including enzymes and  hydrochloric acid) that break down the food into a semiliquid mass called chyme.  The chyme passes into the small intestine, where food molecules are broken down  into sugars, amino acids, and fatty acids. These useful substances are absorbed into  the bloodstream as the food passes through the duodenum, jejunum, and ileum. The  pancreas secretes digestive enzymes into the duodenum. The liver secretes bile salts  that make insoluble fats entering the small intestine water-soluble and vulnerable to  enzymatic action. Excess bile salts are stored in the gallbladder. The large intestine  (colon) serves to remove water and electrolytes from the digested chyme and to  compact and store undigestible material, called feces.

Opposed to contemporary efforts to trans�  form the methodology of the humanities and the social sciences on the  model of natural science, Dilthey tried to establish these fields as inter�  pretive sciences in their own right. Their subject matter, according to him,  is the human mind, not as it is enjoyed in immediate experience nor as it  is analyzed in psychological theory, but as it manifests or �objectifies�  itself in languages and literatures, actions, and institutions. Dilthey  emphasized that the essence of human beings cannot be grasped by intro�  spection but only from a knowledge of all of history; this understanding,  however, can never be final because history itself never is.

The doctrine provides a mitigating defense in cases in which the  mental disease or defect is not of such magnitude as to exclude criminal  responsibility altogether. Diminished responsibility is most frequently  asserted as a defense to murder charges that require proof of a particular  mental state (e.g., premeditation). If diminished responsibility is shown,  negating an element of the crime with which a defendant is charged, the  defendant can be convicted only of a lesser offense that does not include  the element.

After leading a communist uprising in 1923 that provoked  fierce government reprisals, he was forced to live abroad and became head  of the central European section of the Comintern in Berlin (1929-33). He  won worldwide fame for his defense against Nazi accusations in the Reichs�  tag fire trial of 1933. He headed the Comintern in Moscow (1935�43),  then returned to Bulgaria, where he served as prime minister (1945-49).

Dinesen married her cousin, a  baron, and they moved to Kenya; Out of Africa (1937; film, 1985), a  memoir of her years on their coffee plantation (1914-31), reveals a deep  love of Africa and its people. Her characteristic writings took the form  of highly polished narratives in the Romantic tradition, set in the past and  pervaded with an aura of supematuralism; they incorporate themes of eros  and dreams.

It has  short, soft fur, a bushy tail, and erect,  pointed ears. It is about 4 ft (1.2 m)  long, including the 12-in. (30-cm)  tail, and stands about 24 in. (60 cm)  tall at the shoulder. Its colour varies  from yellowish to reddish brown,  often with white underparts, paws,  and tail tip. Dingoes hunt alone or in  small groups. They formerly preyed  mostly on kangaroos but now feed  mainly on rabbits and sometimes on  livestock. They contributed, through  competition for resources, to the  extermination of the Tasmanian wolf  and the Tasmanian devil on the Australian mainland.</p><p>Dinka Cattle-herding people of the Nile basin in southern Sudan.

The  various species appeared at different times, and not all overlapped. The  shape of the teeth reveal whether a given dinosaur was a carnivore or  herbivore. Dinosaurs are classified as either ornithischians or saurischians,  based on pelvic girdle structure. Most had a long tail, which they held  straight out, apparently to maintain balance. Most, if not all, were egg  layers. Some were probably warm-blooded. Dinosaur fossils have been  found on every continent, including Antarctica. Most types of dinosaurs  flourished until late in the Cretaceous Period (65 million years ago), then  disappeared within the next million years. Two theories for the cause of  this mass extinction, following some 140 million years of existence, are  that mountain-building cycles altered habitat and changed climate or that  an asteroid hit the Earth, resulting in immense dust clouds that blocked  sunlight for several years. Birds are thought to be living descendants of  the dinosaurs. See also carnosaur; sauropod.</p><p>Skeletons of an ornithischian dinosaur (Stegosaurus) and a saurischian dinosaur  (Deinonychus).

Diodes (b. ad</p><p>245, Salonae?, Dalmatia�d. 316,</p><p>Salonae) Roman emperor (284-  305). He was serving under the  emperor Carinus (r. 283-285) when  the co-emperor, Carinus�s brother  Numerian, was killed. Diocletian�s  army declared him emperor, but his  domain was restricted to Asia Minor  and possibly Syria. Carinus attacked  Diocletian (285) but was assassi�  nated before achieving victory,  allowing Diocletian to become sole  emperor. He sought to remove the  military from politics and estab�  lished a tetrarchy (four-ruler system)  to spread his influence and combat  rebellions throughout the empire.</p><p>Proclaiming himself and his corulers  as gods, he added the trappings of a  theocracy to the reign. His fiscal,  administrative, and military reorga�  nization laid the foundation for the  Byzantine empire in the east and briefly strengthened the fading empire in  the west. In 303-304 he issued four edicts decreeing the last great per�  secution of Christians. He abdicated in 305.</p><p>Diocletian window Semicircular window divided into three lights  (compartments) by two vertical mullions, with the central light usually  wider than the two side lights. Its name comes from its use in the Baths  of Diocletian in Rome (ad 302).

An applied voltage can cause electrons to flow in only one  direction, from the cathode to the anode, and then back to the cathode  through an external circuit. Diodes are used especially as rectifiers�  which change alternating current into direct current �and to vary the  amplitude of a signal in proportion to the voltage in a circuit, as in a radio  or television receiver. The most familiar diodes are vacuum tubes and semi�  conductor diodes. Semiconductor diodes, the simplest of semiconductor  devices, consist of two electrodes and a sandwich of two dissimilar semi�  conducting substances (a p-n junction). Such diodes form the basis for  more complex semiconductor devices (including transistors) used in com�  puters and other electronic equipment. Semiconductor diodes include  light-emitting diodes and laser diodes; the latter emit laser light, useful for  telecommunications via fibre optics and for reading compact discs.</p><p>Diogenes of Sinope \dI-'aj-3- l nez...s3- , n6-pe\ (b. Sinope,</p><p>Paphlygonia�d. c. 320 bc, probably Corinth) Greek philosopher, princi�  pal member of the Cynics. He is credited by some with originating the  Cynic way of life, but he himself acknowledged his debt to Antisthenes  (c. 445-365 bc). He conveyed the Cynic philosophy by personal example  rather than through any system of thought. He strove to destroy social  conventions (including family life) as a way of returning to a �natural�  life. To this end he lived as a vagabond pauper, sleeping in public build�  ings and begging for food. He also advocated shamelessness (performing  harmless unconventional actions), outspokenness, and training in auster�  ity.</p><p>Diomede VdI-3-,med\ Islands Two islands in the Bering Strait. Lying  about 2.5 mi (4 km) apart, they are separated by the U.S.-Russian bound�  ary, which coincides with the International Date Line.

To the east lies Little Diomede Island, a part  of Alaska.</p><p>Diomedes \ 1 dI-3-'me- l dez\ Greek hero in the Trojan War. He was com�  mander of 80 ships from Argos bringing soldiers to defeat Troy. His  exploits included wounding the goddess Aphrodite, killing Rhesus and his  Thracian followers, and stealing the Trojan Palladium (the sacred image  of Athena that protected Troy). Aphrodite punished him by making his</p><p>wife unfaithful to him in his absence, and after the war he returned home  to find his claim to the throne of Argos disputed. He then sailed to Italy  and founded the colony of Argyripa (later Arpi) in Apulia.</p><p>Dionysia See Bacchanalia</p><p>Dionysius I or Dionysius the Elder (b. c. 430 bc �d. 367) Tyrant  of Syracuse (405-367). He became ruler with Spartan help and retained  power until his death, basing his strength on the support of his mercenary  army. He held Carthaginian expansion on Sicily in check and hoped to  acquire an empire in Greek Italy. Syracuse�s economy depended on war,  and under Dionysius great advances were made in the technology of  large-scale artillery and the manufacture of munitions. His disastrous third  campaign against the Carthaginians resulted in the ceding of money and  territory; he died during the next Carthaginian conflict.</p><p>Dionysius of Halicarnassus (fl. c. 20 bc) Greek historian and  teacher of rhetoric. Born in Halicarnassus, Caria (Asia Minor), Dionysius  went to Rome in 30 bc. His history of Rome, from its origins to the First  Punic War, is written from a pro-Roman standpoint but carefully  researched. It is, with Livy�s, the most valuable source for early Roman  history. Its 20 books began to appear in 7 bc; the last 10 have been lost.</p><p>Dionysius the Areopagite X.ar-e-'a-po-jlt, .ar-e-'a-ps-.gfiA (fl. 1st  century) Biblical figure, converted by St. Paul. His conversion at Athens  is mentioned in Acts 17:34, and he acquired a posthumous reputation  largely through confusion with later Christians similarly named. Around  ad 500, a series of influential Greek treatises uniting Neoplatonism and  Christian theology were forged in his name; the writer, probably a Syr�  ian monk, is now known as Pseudo-Dionysius the Areopagite.</p><p>Dionysus \,dI-9-'nI-s9s\ Greek god of vegetation and fruitfulness,  known especially as the god of wine and ecstasy. His Roman equivalent  was Bacchus. His worship was introduced into Greece from Asia Minor,  and he became one of the most important of all the Greek gods, while his  cult remained associated with that of many Asiatic deities. A son of Zeus  and (according to the standard tradition) Semele, he was brought up by the  maenads, or bacchantes. The first creator of wine, he traveled widely teach�  ing the winemaking art, with a following of satyrs, sileni (see satyr and  silenus), and nymphs. He had the gift of prophecy and was received at Del�  phi along with Apollo, though his principal oracle was at Thrace. Festivi�  ties called Dionysia or (among the Romans) Bacchanalia were held in his  honor; in their earlier years they were wild, ecstatic occasions, and they  have often been the subject of artistic representation. Dionysus originally  appeared as a bearded man, but later more often as a slim youth. His prin�  cipal attribute was the thyrsus, a wand bound with vine leaves. The  dithyramb, a choral hymn in his honor, is often seen as the basis of West�  ern drama.</p><p>Diop VjopV Birago Ismael (b. Dec. 11, 1906, Dakar, French West  Africa�d.

Zeus later  changed them into the constellation Gemini. They were believed to have  aided the Romans in an important battle early in their history, and a temple  in their honour was built in the Roman Forum.</p><p>dioxin \dl-'ak-s3n\ Aromatic compound, any of a group of contaminants  produced in making herbicides (e.g., Agent Orange), disinfectants, and  other agents. Their basic chemical structure consists of two benzene rings  connected by a pair of oxygen atoms; when substituents on the rings are  chlorine atoms, the molecules are particularly toxic. The best-known,  usually called simply dioxin, is 2,3,7,8-tetrachlorodibenzo-/?-dioxin  (2,3,7,8-TCDD). It is extremely stable chemically; it does not dissolve in  water but dissolves in oils (and thus accumulates in body fat). The extent  of its human toxicity is disputed and the subject of continuing research.</p><p>diphtheria \dif-'thir-e-9\ Acute infectious bacterial disease caused by  Corynebacterium diphtheriae. The bacterium usually enters through the  tonsils, nose, or throat and multiplies there, forming a thick membrane  that adheres to the tissues and sometimes blocks the trachea, requiring  emergency treatment.The bacteria produce a toxin that spreads to cause  other symptoms, including fever, chills, sore throat, and lesions in heart  muscle and peripheral nerve tissue that may cause death from heart fail�  ure and paralysis. Diphtheria is treated with an antitoxin that neutralizes  the toxin and produces long-term immunity. Vaccination has greatly  reduced its occurrence in Europe and North America.</p><p>Diplodocus Xds-'pla-ds-kssX Genus of sauropod dinosaur found as fos�  sils in Late Jurassic rocks of North America and related to Apatosaurus.  Diplodocus and its relatives (diplodocids) were some of the longest land  animals that ever lived, some approaching 100 ft (30 m). It had a long  neck and extremely small brain and skull. Most diplodocids weighed  about 30 tons, and some as much as 80 tons. It was formerly thought that  Diplodocus may have spent a good deal of time in water, but fossil evi�  dence indicates it moved freely on land, where it apparently fed on soft  vegetation. It may be the most commonly displayed dinosaur.</p><p>diploidy See ploidy</p><p>diplomacy Art of conducting relationships for gain without conflict. It  is the chief instrument of foreign policy. Its methods include secret nego�  tiation by accredited envoys (though political leaders also negotiate) and  international agreements and laws. Its use predates recorded history. The  goal of diplomacy is to further the state�s interests as dictated by geog�  raphy, history, and economics. Safeguarding the state�s independence,  security, and integrity is of prime importance; preserving the widest pos�  sible freedom of action for the state is nearly as important. Beyond that,  diplomacy seeks maximum national advantage without using force and  preferably without causing resentment.</p><p>diplomatic service See foreign service  diplopia See double vision</p><p>Dipo Negoro Vde-po-ne-'gor-oV Pangeran (Prince) (b. c. 1785,  Jogjakarta, Java�d. Jan. 8, 1855, Macassar [Ujung Pandang], Celebes)  Javanese leader in the 19th-century conflict known to the West as the Java  War (1825-30). He was the son of the ruler of Jogjakarta, a sultanate cre�  ated in 1755 by a Dutch treaty that dismembered the once-powerful Jav�  anese kingdom of Mataram. Dutch land reforms undercut the economic  position of the Javanese aristocrats, and Dipo Negoro became the aristo�</p><p>crats� leader against the Dutch. The Javanese saw him as a �just prince�  come to save the people, and the conflict itself was seen as a Muslim holy  war against the infidels. For three years Dipo Negoro�s guerrilla forces  had the upper hand, but the Dutch triumphed in the end. Dipo Negoro  was arrested at the peace negotiations and died in exile.</p><p>dipole See electric dipole, magnetic dipole</p><p>dipper or water ouzel \'U-zsl\ Any of five songbird species in the  genus Cinclus (family Cinclidae),  noted for hunting insects by walking  underwater in rushing streams.

Dipterans live in all habitats worldwide, including the  subarctic and high mountains. They range in size from about 0.05 in. (1  mm) long (midges) to 3 in. (8 cm) long (robber flies). Dipteran larvae break  down and redistribute organic materials, and both adults and larvae are a  significant link in numerous food chains. Many species are annoying  bloodsuckers, and several (e.g., housefly, mosquito, sand fly, tsetse fly) are  vectors of disease. Other species cause great damage to agricultural crops.

Oct. 20, 1984, Tallahassee, Fla., U.S.)  English mathematician and theoretical physicist. His first major contri�  bution (1925-26) was a general and logically simple form of quantum  mechanics. About the same time, he developed ideas of Enrico Fermi, which  led to the Fermi-Dirac statistics. He then applied Albert Einstein�s special  theory of relativity to the quantum mechanics of the electron and showed  that the electron must have spin of Vi. Dirac�s theory also revealed new  states later identified with the positron. He shared the 1933 Nobel Prize  for Physics with Erwin Schrodinger. In 1932 Dirac was appointed Luca�  sian Professor of Mathematics at the University of Cambridge, a chair  once occupied by Isaac Newton. Dirac retired from Cambridge in 1969  and held a professorship at Florida State University from 1971 until his  death.</p><p>dire wolf Extinct wolf ( Canis dims ) that existed during the Pleistocene  Epoch (1.8 million-10,000 years ago), probably the most common mam�  malian species found preserved in the La Brea Tar Pits. It differed from the  modern wolf in being larger and having a more massive skull, a smaller  brain (and probably less intelligence), and relatively light limbs. The spe�  cies was considerably widespread; skeletal remains have been found in  Florida and the Mississippi valley in the U.S., as well as in the Valley of  Mexico.</p><p>direct current (DC) Flow of electric charge that does not change direc�  tion. Direct current is produced by batteries, fuel cells, rectifiers, and gen�  erators with commutators. Direct current was supplanted by alternating  current (AC) for common commercial power in the late 1880s because it  was then uneconomical to transform it to the high voltages needed for  long-distance transmission. Techniques developed in the 1960s overcame  this obstacle, and direct current is now transmitted over very long dis�  tances, though it must ordinarily be converted to alternating current for  final distribution. For some uses, such as electroplating, direct current is  essential.</p><p>direct-mail marketing Method of merchandising in which the sell�  er�s offer is made through mass mailing of a circular or catalog or through  a newspaper or magazine advertisement, and in which the buyer places  an order by mail, telephone, or Internet.

Until the late 19th century, a theatrical  director was usually the play�s leading actor or the company�s actor-  manager. Today�s stage director combines elements such as actors, decor,  costumes, and lighting to shape an imaginative interpretation of the play�  wright�s script. The director must understand the art of acting and pro�  vide guidance for the actors. The director also composes the �stage  pictures,� the shifting arrangements of the actors and other elements on  the stage. The film director combines the theatrical director�s responsi�  bilities with the technical functions of cinematography, editing, and sound  recording. See also actor-manager system; auteur theory.</p><p>Directoire style \de-rek-'twar\ Style of dress, furniture, and ornament  popular in France during the Directory, 1795-99. Dress for men mixed  the ancient and contemporary: high boots, vests, open coats, top hats.  Women�s fashions featured dresses with long sleeves and V necklines,  worn with ruffled caps. Directoire furniture and ornamentation were based  on ancient Roman objects recently excavated at Pompeii.</p><p>Directory French Directoire \de-rek-'twar\ (1795-99) Government  set up during the French Revolution by the Constitution of 1795. Legis�  lative power was placed in the Council of Five Hundred and the Council  of Ancients, while executive power was placed in a five-member Direc�  tory. Though the Directors nominally inherited many of the powers of the  Committee of Public Safety, they had no funds to finance their projects or  courts to enforce their will. The regime was marked by administrative  chaos and corruption and by the uprisings in the Vendee.

He  served in the U.S. House of Representatives (1932�48), where he voted  against most New Deal measures and remained an isolationist until the  U.S. entered World War II. He later served in the U.S. Senate (1950-69),  becoming minority leader in 1959. He was noted for his oratorical style.

Disc jockey programs became  the economic base of many radio stations in the U.S. after World War II.  The format generally involves one person, the disc jockey, introducing  and playing phonograph records and chatting informally, usually extem�  poraneously, in the intervals. Because popular DJs are in a position to  influence public tastes, record companies have sometimes attempted to  bribe them with money and gifts, known as �payola.�</p><p>Disciples of Christ Group of U.S. Protestant churches that originated  in the frontier revivals of the early 19th century. Movements founded by  Thomas and Alexander Campbell (1763-1854, 1788-1866) and Barton  W. Stone (1772-1844) merged in 1832 and took the name Disciples of  Christ. The new denomination grew rapidly. Its goal was to unite all Prot�  estants on the basis of New Testament practices. The attempt failed, and  the movement itself split into two major segments: the more conservative  Churches of Christ (which rejects any innovation without New Testament  precedent, including musical instruments in worship) and the Christian  Church (Disciples of Christ). Other conservative congregations separated  from the Christian Church (Disciples of Christ) in the 1920s; they estab�  lished a separate annual gathering, the North American Christian Con�</p><p>vention, in 1927. In 1985 the Disciples of Christ entered into an  ecumenical partnership with the United Church of Christ. The common  Disciples heritage is still manifest in the meetings of the World Conven�  tion of Churches of Christ, organized in 1930.</p><p>disco Style of dance music that arose in the mid-1970s, characterized by  hypnotic rhythm, repetitive lyrics, and electronically produced sounds.  Disco (short for discotheque) evolved largely from New York City under�  ground nightclubs, in which disc jockeys would play dance records for  hours without interruption, taking care to synchronize the beats so as to  make a seamless change between records. Artists such as Donna Summer,  Chic, and the Bee Gees had many hits in the genre, which peaked with  the release of the film Saturday Night Fever (1977). Disco faded quickly  after 1980, but its powerful influence, especially its sequenced electronic  beats, still continues to affect much of pop music.</p><p>discount rate or bank rate Interest rate charged by a central bank  for loans of reserve funds to commercial banks and other financial inter�  mediaries. The discount rate is one important indicator of the condition  of monetary policy in an economy. Because raising or lowering the dis�  count rate alters the rates that commercial banks charge on loans, adjust�  ment of the discount rate is used as a tool to combat recession and inflation.</p><p>discovery In law, pretrial procedures providing for the exchange of  information between the parties involved. Discovery may be made  through interrogatories, written questions sent from one side to the other  in an attempt to secure important facts. It also can be made through depo�  sitions, whereby a witness is sworn and, in the presence of attorneys for  both sides, is subjected to questions. (The written record of the proceed�  ings also is called a deposition.) Other forms of discovery include an order  of production and inspection, which compels the opposing party to pro�  duce relevant documents or other evidence, and requests for medical  examination in cases in which a party�s mental or physical condition is  at issue.</p><p>discus throw Track-and-field sport of hurling for distance a disk�  shaped object known as a discus. The discus is 8.6 in. (219 mm) in diam�  eter and is thicker in the centre than at the perimeter; it must weigh at  least 4.4 lbs (2 kg) for men�s events, 2.2 lbs (1 kg) for women�s. It is  thrown by means of a whirling movement made by the athlete within a  circle 8.2 ft (2.5 m) in diameter. The sport dates back to the ancient Greek  Olympics.</p><p>disk, hard See hard disk  disk flower See composite family  diskette See floppy disk</p><p>dislocation Displacement of the bones of a joint. It disrupts the liga�  ments, muscles, and capsule (encasing membrane) holding the joint in  place. The joint, painful and tender, appears misshapen and swollen, with  discoloration of the overlying skin. The patient cannot use the joint and  often feels a grating or grinding sensation on trying to move it. The bones  must be returned to their normal position (reduction) and the joint kept  immobile until healed. Recurrent and congenital dislocations usually  require surgical reconstruction.</p><p>Dismal Swamp or Great Dismal Swamp Wetland region, south�  eastern Virginia and northeastern North Carolina, U.S. Despite much lum�  bering and widespread destruction by fire, the area is still heavily wooded.  About 30 mi (48 km) long and 10 mi (16 km) wide, it is home to many  rare birds and numerous poisonous</p><p>snakes. Noted for its fishing and  hunting, it is traversed by the Dismal  Swamp Canal, part of the Atlantic  Intracoastal Waterway.</p><p>Disney, Walt(er Elias) (b. Dec.  5, 1901, Chicago, Ill., U.S.�d. Dec.  15, 1966, Los Angeles, Calif.) U.S.  animator and entertainment execu�  tive. In the 1920s he joined with his  brother Roy and his friend Ub Iwerks  (1901-71) to establish an animation  studio.

The brothers formed Walt Disney Productions (later the Disney Co.) in  1929. Mickey Mouse�s instant popularity led them to invent other char�  acters such as Donald Duck, Pluto, and Goofy and to make several short  cartoon films, including The Three Little Pigs (1933). Their first full-  length animated film, Snow White and the Seven Dwarfs (1937), was fol�  lowed by classics such as Pinocchio (1940), Fantasia (1940), and  Cinderella (1950). A perfectionist, an innovator, and a skilled business�  man, Walt Disney maintained tight control over the company in both cre�  ative and business aspects. He oversaw the company�s expansion into  live-action films, television programming, theme parks, and mass mer�  chandising. By his death in 1966, Disney had transformed the family  entertainment industry and influenced more than one generation of Ameri�  can children.</p><p>Disney Co. U.S. entertainment corporation. It was founded by Walt  Disney and his brother Roy as Walt Disney Productions in 1929 to incor�  porate their cartoon animation studio. It produced short and full-length  animated cartoons in the 1930s and 1940s, then expanded in the 1950s  to make nature documentaries and live-action films as well as television  programs. The opening of the amusement parks Disneyland (1955) and  Walt Disney World (1971; see Disney World and Disneyland) strengthened  the company�s dominance of the family entertainment industry in the U.S.  The company declined after Disney�s death in 1966 but was revitalized  under new management in the 1980s. As the Walt Disney Co. it expanded  its production units to include Touchstone Pictures and Miramax, makers  of films for more mature audiences, and revitalized its animation divi�  sion, producing films such as The Little Mermaid (1989) and Toy Story  (1995), the first full-length computer-animated film. The company took  an active role in reviving and commercializing New York City�s Times  Square, including the recreation of some of its animated films, such as  The Lion King (1994), as Broadway musicals. In 1994 it opened Celebra�  tion, a planned community in central Florida. It acquired the ABC tele�  vision network in 1996 and became the world�s largest media and  entertainment corporation; it also operates the cable television Disney  Channel. See also Michael Eisner.</p><p>Disney World and Disneyland Two theme parks built by the Walt  Disney Co. (see Disney Co.), a U.S. corporation that became the best-  known 20th-century purveyor of entertainment. Disneyland, an interac�  tive, family-oriented fantasy environment that opened in Anaheim, Calif.,  in 1955, was Walt Disney�s response to typical amusement parks, which  entertained children but not their parents. The park, which has architec�  ture that is a blend of futurism and nostalgic 19th-century reproductions,  has different sections devoted to specific themes. Walt Disney World  opened near Orlando, Fla., in 1971. Besides containing Epcot Center (an  idealized city), Disney-MGM Studios, and the Magic Kingdom and Ani�  mal Kingdom theme parks, Disney World was the first amusement park  to incorporate hotels (including two designed by Michael Graves) and  sports and other recreational facilities into its master plan. In the late 20th  century new Disney theme parks also opened in Paris and Tokyo.</p><p>disorderly conduct Conduct likely to lead to a disturbance of the  public peace or that offends public decency. It has been held to include  the use of obscene language in public, fighting in a public place, block�  ing public ways, and making threats. Statutes against disorderly conduct  must identify the specific acts that constitute it. The offense usually car�  ries minor penalties.</p><p>dispersion Any phenomenon associated with the propagation of indi�  vidual waves at speeds that depend on their wavelengths. Wavelength  determines the speeds at which waves travel through media. This varia�  tion in speed causes radiation to separate into components that have dif�  ferent frequencies and wavelengths. For example, when a beam of white  light is sent through a glass prism, refraction causes the beam to disperse  into an array of its component colours of light, producing a rainbowlike  effect.</p><p>displacement activity Performance by an animal of an act inappro�  priate for the stimulus or stimuli that evoked it. It usually occurs when  an animal is torn between two conflicting drives, such as fear and aggres�  sion. Displacement activities often consist of comfort movements (e.g.,  grooming, scratching).</p><p>display behaviour Ritualized activity by which an animal conveys  specific information. The best-known displays are visual, but others rely  on sound, smell, or touch. Agonistic (aggressive) displays make it unnec�</p><p>essary to chase intruders from a territory or for animals to injure each  other in competition for mates. One type of defensive display deceives  predators or lures them away from vulnerable young. See also birdsong;  COURTSHIP BEHAVIOUR.</p><p>disposable income Portion of an individual�s income over which the  recipient has complete discretion. To assess disposable income, it is nec�  essary to determine total income, including not only wages and salaries,  interest and dividend payments, and business profits, but also transfer  income such as social-security benefits, pensions, and alimony. Obliga�  tory payments, including personal income taxes and compulsory social-  insurance contributions, must be subtracted. Disposable income may be  used for consumption or saving.</p><p>Dispur \dis-'pur\ City, capital of Assam state, northeastern India.

Dec. 21,  1804, London, Eng.�d. April 19, 1881, London) British politician and  author who was twice prime minister (1868, 1874-80). Of Italian-Jewish  descent, he was baptized a Christian as a child, which enabled his future  career, because until 1858, practitioners of Judaism were excluded from  Parliament. He first made his mark as a writer with Vivian Grey (1826�  27); later novels included Coningsby (1844) and Sybil (1845). He was  elected to Parliament as a Conservative in 1837. In 1845 he made a series  of brilliant speeches against Sir Robert Peel�s decision to repeal the Corn  Laws, which helped him to become leader of the Conservatives. He served  three stints as chancellor of the Exchequer (1852, 1858-59, 1865-68) and  played a prominent role in passing the Reform Bill of 1867. He was prime  minister briefly in 1868, then returned in his second ministry (1874-80)  to promote social reform. An advocate of a strong foreign policy, he  secured a triumph for imperial prestige with his acquisition of Suez Canal  shares and won concessions for England at the Congress of Berlin. A  trusted friend of Queen Victoria, he introduced a bill conferring on her the  title Empress of India. After the Conservatives were defeated in 1880, he  kept the party leadership and finished his political novel Endymion (1880).</p><p>dissociation Breaking of a chemical compound into simpler constitu�  ents as a result of added energy, as in the case of gaseous molecules dis�  sociated by heating; also, the effect of a solvent on a dissolved polar  compound (electrolyte), as in the case of an inorganic salt, such as sodium  chloride, dissolved in water. All electrolytes dissociate into ions to a  greater or lesser extent in polar solvents (in which the molecules are elec�  tric dipoles). The degree of dissociation can be used to determine the equi�  librium constant. Dissociation is used to explain electrical conductivity and  many other properties of electrolytic solutions.</p><p>dissociative identity disorder formerly multiple personality  disorder Rare condition indicated by the absence of a clear and com�  prehensive identity. In most cases two or more independent and distinct  personality systems develop in the same individual. Each personality may  alternately inhabit the person�s conscious awareness to the exclusion of  the others, but one is usually dominant. The various personalities typi�  cally differ from one another in outlook, temperament, and body language  and might assume different first names. The condition is generally viewed  as resulting from dissociative mental processes�that is, the splitting off  from conscious awareness and control of thoughts, feelings, memories,  and other mental components in response to situations that are painful,  disturbing, or somehow unacceptable to the person experiencing them.  Treatment is aimed at integrating the disparate personalities back into a  single and unified personality.</p><p>dissonance See consonance and dissonance  dissonance, cognitive See cognitive dissonance</p><p>distaff Device used in hand spinning in which individual fibres are  drawn out of a mass of prepared fibres held on a stick (the distaff), twisted  together to form a continuous strand, and wound on a second stick (the  spindle). It is most often used for making linen; wool does not require a  distaff (see carding). The first stage in mechanizing spinning was to mount  the spindle horizontally in bearings to rotate with a large hand-driven  wheel; the distaff, carrying the mass of fibre, was held in the left hand,  and the spinning wheel slowly turned with the right. The Saxon, or Sax�  ony, wheel incorporated a bobbin on which the yarn was wound continu�  ously; the distaff holding the raw fibre became a stationary vertical rod,  and the wheel was activated by a foot treadle, freeing both the operator�s</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>distance formula &#x25BA; diverticulum I 553</p><p>hands.

In two- and three-dimensional Euclidean space, the distance formu�  las for points in rectangular coordinates are based on the Pythagorean  theorem. The distance between the points (a,b) and ( c,d) is given by  V(a - c ) 2 + (b - d) 2 . In three dimensional space, the distance between the  points (a, b, c ) and ( d , e, f) is �n J(a - d) 2 + (b � e ) 2 + (c - f) 2 .</p><p>distemper Viral disease in two forms, canine and feline. Canine dis�  temper is acute and highly contagious, affecting dogs, foxes, wolves,  mink, raccoons, and ferrets. Most untreated cases are fatal. Infected ani�  mals are best treated with prompt injections of serum globulins; second�  ary infections are warded off by antibiotics. Immunity can be conferred  by vaccination. Feline distemper causes a severe drop in the number of  the infected cat�s white blood cells. It rarely lasts more than a week, but  the mortality rate is high. Vaccines offer effective immunity.</p><p>disthene See kyanite</p><p>distillation Vaporization of a liquid and subsequent condensation of the  resultant GAS back to liquid form. It is used to separate liquids from non�  volatile solids or solutes (e.g., water from salt and other components of  seawater) or to separate two or more liquids with different boiling points  (e.g., alcohol from fermented beers and wines). Many variations have  been devised for industrial applications. An important one is fractional  distillation, in which vapour from a heated liquid mixture is contacted by  a series of trays and condensed liquid as it rises through a vertical col�  umn. The most volatile fraction of the mixture emerges from the top of  the column, while less volatile fractions are withdrawn at lower points.  In petroleum refining, this method is very efficient for removing naphtha,  kerosene, and gas oils from crude oil.</p><p>A laboratory distillation apparatus demonstrating desalination of water. In the distil�  lation flask, salt water is boiled to produce water vapour, or steam, while the salt  remains in the liquid solution. The vapour rises through the top of the flask and  passes into the condenser, which consists of a glass tube within a larger tube. Cold  water flows through the space between the tubes, cooling the vapour in the inner  tube so that it condenses and flows into the receiving flask.</p><p>� MERRIAM-WEBSTER INC.</p><p>distilled liquor Alcoholic beverage obtained by distillation from wine  or other fermented fruit juice or from various cereal grains that have first  been brewed. The essential ingredient is usually a natural sugar or a  starchy substance that may be easily converted into a sugar. The distil�  lation process is based on the different boiling points of water (212 �F  [100 �C]) and alcohol (173 �F [78.5 �C]). The alcohol vapours that arise  while the fermented liquid boils are trapped and recondensed to create a  liquid of much greater alcoholic strength. The resultant distillate is  matured, often for several years, before it is packaged and sold.

In sym�  bols, it is stated; a{b + c) = ab + ac. The monomial factor a is distributed,  or separately applied, to each term of the polynomial factor b + c, resulting  in the product ab + ac. It can also be stated in words: The result of first  adding several numbers and then multiplying the sum by some number is  the same as first multiplying each separately by the number and then adding  the products.

Originally  100 sq mi (259 sq km), the territory was authorized by Congress in 1790  and granted by Maryland and Virginia; it now occupies 68 sq mi (176 sq  km). The site was chosen by Pres. George Washington and became the  seat of the federal government by 1800. Part of the district (Alexandria,  Va.) was retroceded to Virginia in 1847. The slave trade was prohibited  in the District in 1850 and slavery was abolished in 1862. The territorial  government was abolished in 1874 in favour of government by a com�  mission appointed by the president. Residents were granted suffrage in  national elections in 1961 by the 23rd Amendment to the U.S. Constitu�  tion. The mayor-council form of government was established in 1967.  Originally appointees of the president, the mayor and councilors became  elected officials in 1973 and received local legislative powers in 1974.</p><p>dithyramb \'dith-i-,ram(b)\ Choric poem, chant, or hymn of ancient  Greece. Dithyrambs were sung by revelers at the festival in honour of  Dionysus. The form originated about the 7th century bc in extemporane�  ous songs of banqueters; it was a recognized literary genre by the end of  the 6th century bc. Dithyrambs were composed by Arion and Pindar,  among others. By c. 450 bc the form was in decline; most dithyrambs  were bombastic and turgid.</p><p>Differs von Dittersdorf Vdit-ors-.dorft, Carl orig. Carl Differs (b.</p><p>Nov. 2, 1739, Vienna, Austria�d.

Though  ennobled by the empress in 1773, he apparently declined the offer of the  post of kapellmeister at the imperial court in Vienna. Extremely prolific,  he wrote some 120 symphonies, some 40 concertos (many for violin),  sacred choral works, and many chamber pieces. Most important are some  40 stage works, particularly his singspiels, including Doctor und  Apotheker (1786) and Die Liebe im Narrenhause (1787).</p><p>diuretic \,dl-yur-'e-tik\ Any drug that increases the flow of urine from  the body. Diuretics promote removal of excess water, salts, poisons, and  metabolic wastes to help relieve edema, kidney failure, or glaucoma. Most  types act by decreasing the amount of fluid that is reabsorbed by the kid�  ney�s nephrons and passed back into the blood. Diuretics that allow the  body to retain potassium are used for patients with hypertension or conges�  tive HEART FAILURE.</p><p>Divali or Diwali Vdo-'wa-le, d3-'va-le\ In Hinduism, a five-day religious  festival in autumn. It honors Lakshmi, goddess of wealth, or, in Bengal, the  goddess Kali. During its celebration, earthenware lamps are lit and placed  on the parapets of houses and temples or set adrift on rivers and streams.  The fourth day of the festival marks the start of a new year, a time of  gift-giving, visiting friends, decorating homes, and wearing new clothes.

Mild cases need only  bed rest and antibiotics. In severe cases, perforation or rupture of the colon  wall at the diverticulum can cause peritonitis. Rupture may require colos�  tomy. Meckel diverticulum, a congenital malformation of the upper intes�  tine that causes bleeding and inflammation, may require surgical removal.</p><p>divertimento Xdi-.vor-ti-'men-toN Eighteenth-century chamber music  genre consisting of several movements, often of a light and entertaining  nature, for strings, winds, or both. Though the name was applied (c.  1750-1800) to a confusingly varied range of works, it almost always  referred to pieces with a single instrument to a part; this could include  string quartets and even keyboard sonatas.</p><p>dividend Individual share of earnings distributed among stockholders  of a corporation or company in proportion to their holdings. Usually paid  in cash, dividends may also be distributed in the form of additional shares  of stock. Preferred stockholders receive a preferential dividend, usually  at a fixed rate; common stockholders get a portion of what remains after  payment of the dividends on preferred stock.</p><p>dividing engine Machine used to mark off equal intervals accurately,  usually on precision instruments. Georg Friedrich von Reichenbach  (1772-1826), a German maker of astronomical instruments, designed an  early dividing engine, and Jesse Ramsden (1735-1800), a British pioneer  in the design of precision tools, designed dividing engines of great accu�  racy for both circles and straight lines and produced highly accurate sex�  tants, theodolites (see surveying), and vertical circles for astronomical  observatories.</p><p>divination Practice of discerning the hidden significance of events and  foretelling the future. Divination is found in all societies, ancient and  modern, though methods vary. In the West, psychics claim innate ability  to predict the future, and horoscopes, palm reading, and tarot cards are  popular methods of divination. Other methods involve or have involved  interpreting dreams, discovering omens in natural events, reading the  entrails of animals, casting lots, and consulting oracles. Divination has  long been viewed as the province of specially gifted persons, such as  prophets, shamans, and magicians. See also astrology.</p><p>Divine, Father orig. George Baker (b. 1880?, Georgia?, U.S.�d.  Sept. 10, 1965, Philadelphia, Pa.) U.S. religious leader. Reportedly born  on a plantation, he began preaching in 1899 in the South and later in Bal�  timore, Md., as �The Messenger.� He settled in New York City in 1915  and adopted the name Major J. Devine (later altered to Father Divine).  In 1919 he established his first communal settlement in Sayville on Long  Island, and he founded the Peace Mission movement. His predominantly  black following expanded rapidly in the 1930s and �40s, and his settle�  ments, called �heavens,� eventually numbered about 170. He taught his  followers to renounce personal property, and the strict moral code he  preached included celibacy and a ban on alcohol and tobacco. Many of  his followers, called �angels,� believed him to be God.</p><p>divine kingship Religio-political concept that views a ruler as an  incarnation, manifestation, mediator, or agent of the sacred. In some non�  literate societies, members view their rulers or chiefs as inheritors of the  community�s own magical power. The ruler may exercise this power  either malevolently or benevolently, but he is usually responsible for influ�  encing the weather and the land�s fertility to ensure the harvest necessary  for survival. In other societies, particularly those of ancient China, the  Middle East, and South America, the ruler was identified with a particu�  lar god or as a god himself; in Japan, Peru (among the Inca), Mesopot�  amia, and the Greco-Roman world, the ruler was regarded as the son of  a god. In either case�whether the ruler embodies his own magical power  or that of the community�the ruler protects the community from enemies  and generally feeds and cares for his people. A third form of divine king-  ship, one practiced in Europe, is that of the ruler as mediator or execu�  tive agent of a god. In this form it is the institution of kingship, more than  an individual ruler, that bears the mark of the sacred.</p><p>diving Sport of plunging into water, usually headfirst and often follow�  ing the execution of one or more acrobatic maneuvers. It emerged as a  competitive sport in the late 19th century and became part of the Olym�  pic Games in 1904. Dives are performed from a firm platform 5 or 10 m  (16.4 or 32.8 ft) above the water, or from a springboard 1 or 3 m (3.3 or  9.8 ft) above the water. In Olympic contests, only the 10-m platform and  3-m springboard are used. Contestants are required to do certain dives,</p><p>as well as dives of their own choice, each rated according to its degree  of difficulty. Judges score each dive, and the total score is multiplied by  the degree of difficulty.</p><p>diving duck Any duck that obtains its food by diving to the bottom in  deep water rather than by dabbling in shallows (see dabbling duck). Div�  ing ducks prefer marine environments and are popularly called either bay  ducks or sea ducks. Bay ducks (tribe Aythyini, family Anatidae), includ�  ing canvasback, redhead, scaup, and allied species, are found more fre�  quently in estuaries and tidal lagoons than on the open sea. Sea ducks (20  species in tribes Mergini and Somateriini) include the bufflehead, eiders,  goldeneye, mergansers, oldsquaw, and scoters; some are also or mainly  found on inland waters.</p><p>division of labour Specialization in the production process. Complex  jobs can usually be less expensively completed by a large number of  people each performing a small number of specialized tasks than by one  person attempting to complete the entire job. The idea that specialization  reduces costs, and thereby the price the consumer pays, is embedded in  the principle of comparative advantage. Division of labour is the basic  principle underlying the assembly line in mass production systems. See Emile  Durkheim.</p><p>divorce Dissolution of a valid marriage, usually freeing the parties to  remarry. In societies in which religious authority is strong and the reli�  gion holds that marriage is indissoluble (e.g., Roman Catholicism, Hindu�  ism), divorce may be difficult and rare. In the U.S. at the beginning of the  21st century there was about one divorce for every two marriages. The  rate of divorce in the U.S. is greater than it is in most other Western coun�  tries, though divorce rates climbed in those countries in the last decades  of the 20th century. The most common grounds for divorce are absence  from the marital home, drug or alcohol addiction, adultery, cruelty, con�  viction of a crime, desertion, insanity, and nonsupport.

She opened a school for girls in Boston in  1821, and in 1841 she began teaching Sunday school in a jail, where she  was distressed to see the mentally ill imprisoned with criminals. For 18  months she toured mental institutions, and in 1843 she reported their  deplorable conditions to the Massachusetts legislature. After improve�  ments were made, she expanded her campaign to other states. Through  her work, special mental hospitals were built in 15 states and in Canada.</p><p>Dix, Otto (b.

The earliest jazz ensembles grew out of the ragtime and brass bands of  New Orleans, incorporating elements of the blues. In early jazz ensembles,  such as those led by King Oliver and Jelly Roll Morton, the trumpet or  comet plays the melody, with clarinet and trombone providing accompa�  niment. The tension created by soloists contrasts with the release of  ensemble refrains. It is played with a distinctive two-beat rhythm, result�  ing in a joyous cacophony at fast tempos or slow, mournful dirges.

Largely self-  taught, Dixon began his pioneering industrial use of graphite in 1827 with  the manufacture of lead pencils, stove polish, and lubricants. He discov�  ered that graphite crucibles withstood high temperatures, and he secured  patents on graphite crucibles for making steel and pottery. He established  a crucible steelworks in Jersey City in 1850. He also experimented with  photography and photolithography and devised a technique for printing  banknotes in colour to prevent counterfeiting.</p><p>Dixon, Willie orig. William James Dixon (b.

In 1936 Dixon  moved from his native Mississippi to Chicago, won an Illinois Golden  Gloves boxing championship, and began selling his songs. He played  double bass in several bands before joining Chess Records. His lively  compositions, which he sold for as little as $30, included �Little Red  Rooster,� �You Shook Me,� and �Back Door Man�; many were later  recorded by Muddy Waters, Elvis Presley, and the Rolling Stones. Dixon  toured widely throughout the U.S. and Europe.</p><p>Djakarta See Jakarta</p><p>Djibouti \ji-'bu-te\ officially Republic of Djibouti, formerly (1967-</p><p>77) French Territory of the Afars and Issas \a-'far...e-'sa,  a-'farz...e-'saz\ Country, eastern Africa, on the Gulf of Aden at the entrance</p><p>to the Red Sea. Area: 8,950 sq mi (23,200  o 25 so mi SC 1 km). Population (2005 est.): 476,700.</p><p>6 25 ' so 75 km Capital: Djibouti. Roughly half of the</p><p>people are Issas and related Somali clans;  Afars are about one-third; the balance  includes Yemeni Arabs and Europeans, mostly French. Languages:  French, Arabic (both official). Religion: Islam (predominantly Sunni).  Currency: Djibouti franc. Djibouti is divided into three principal regions:  the coastal plain, the volcanic plateaus in the country�s south and centre,</p><p>and the mountain ranges in the north, reaching 6,654 ft (2,028 m) high  at Mount Moussa (Mousa). The land is primarily desert�hot, dry, and  desolate; virtually none is arable. Djibouti has a developing market  economy that is based almost entirely on trade and commercial services,  centring on Djibouti city. The country is a republic with one legislative  house; its head of state and government is the president. Settled by the  Arab ancestors of the Afars, it was later populated by Somali Issas. In  ad 825 Islam was brought to the area by missionaries. Arabs controlled  the trade in this region until the 16th century; it became a French pro�  tectorate in the 19th century. It was made a French overseas territory in  1946, assumed the name French Territory of the Afars and Issas in 1967,  and gained its independence in 1977. In the late 20th century it received  refugees from the Ethiopian-Somali war and from civil conflicts in Eri�  trea. From the 1990s the country experienced political unrest.</p><p>Djibouti City (pop., 1995 est.: 383,000), major port, and capital of Dji�  bouti. Located on the southern shore of the Gulf of Tadjoura in the Gulf  of Aden, it was founded by the French in 1888 and made the capital of  French Somaliland in 1892. Linked by rail to Addis Ababa in 1917, it was  made a free port in 1949. The economic life of both the city and the  nation depends on the city�s function as a transshipment point, especially  between Ethiopia and the Red Sea trade. Built on three level areas linked  by jetties, the city has a mixture of ancient and modem architecture.  Drought and war during the 1980s and early �90s brought many refugees  to Djibouti from Somalia and Ethiopia, swelling its population.</p><p>Djilas Vji-las\, Milovan (b. June 12, 1911, Podbisce, Montenegro�d.  April 20, 1995, Belgrade, Serbia) Yugoslav politician and political writer.  His opposition to Yugoslavia�s royalist dictatorship led to a prison term  (1933-36). He joined the Yugoslav Communist Party�s central  commit}tee in 1938 and its politburo in 1940. In World War II he played  a major role in the partisan resistance to the Germans. In 1953 he became  president of the Federal People�s Assembly, but his criticism of the party  and calls for liberalization soon led to his ouster from all political posts  by Tito. He was later arrested several times after his books criticizing  communism, including The New Class (1957), were published in the  West.</p><p>Dmitry, False or Pseudo-Demetrius Any of three pretenders to  the Muscovite throne who, during the Time of Troubles, claimed to be  Ivan IV�s child Dmitry Ivanovich, who had died mysteriously while still  a child, possibly murdered at the order of Boris Godunov. The first False  Dmitry challenged Godunov�s right to the throne and was proclaimed  tsar in 1605. In 1606 he was murdered by Vasily Shuysky (1552-1612),  who succeeded him. Rumors spread that Dmitry had survived, and a sec�  ond pretender gained a large following before being killed in 1610. A  third False Dmitry appeared in 1611, gaining the allegiance of the Cos�  sacks and the inhabitants of Pskov, but he was executed in 1612.</p><p>DNA or deoxyribonucleic Xde-'ak-si-.ri-bo-nyu-'kle-ik, de-'ak-  si-.ri-bo-nyu-'kla-ikA acid One of two types of nucleic acid (the other is  RNA); a complex organic compound found in all living cells and many  viRUSes. It is the chemical substance of genes. Its structure, with two  strands wound around each other in a double helix to resemble a twisted  ladder, was first described (1953) by Francis Crick and James D. Watson.  Each strand is a long chain (polymer) of repeating nucleotides: adenine (A),  guanine (G), cytosine (C), and thymine (T). The two strands contain  complementary information: A forms hydrogen bonds (see hydrogen  bonding) only with T, C only with G. When DNA is copied in the cell,  the strands separate and each serves as a template for assembling a new  complementary strand; this is the key to stable heredity. DNA in cells is  organized into dense protein-DNA complexes (see nucleoprotein) called  chromosomes. In eukaryotes these are in the nucleus, and DNA also occurs  in mitochondria and chloroplasts (if any). Prokaryotes have a single cir�  cular chromosome in the cytoplasm. Some prokaryotes and a few eukary�  otes have DNA outside the chromosomes in plasmids. See also Rosalind  Franklin; genetic engineering; mutation; Maurice Wilkins.

The procedure consists of obtaining a sample of cells contain�  ing DNA (e.g., from skin, blood, or hair), extracting the DNA, and puri�  fying it. The DNA is then cut by enzymes, and the resulting fragments of  varying lengths undergo procedures that permit them to be analyzed. The  pattern of fragments is unique for each individual. DNA fingerprinting is  used to help solve crimes and determine paternity; it is also used to locate  gene segments that cause genetic diseases, to map the genetic material of  humans (see Human Genome Project), to engineer drought-resistant plants  (see genetic engineering), and to produce biological drugs from genetically  altered cells.</p><p>Dnieper River \'ne-por\ Russian Dnepr Xdo-'nyeprA ancient Borys-  thenes.

June  26, 1957, Emmendingen, near Freiburg im Breisgau, W.Ger.) German  novelist and essayist. He studied medicine at the Universities of Berlin  and Freiburg, specializing in psychiatry. His first novel. The Three Leaps  of Wang-Lun (1915), describes the quashing of a rebellion in China. His  best-known work, Berlin Alexanderplatz (1929; film, 1931; adapted for  television, 1980), is written in an Expressionist vein and dramatizes the  miseries of working-class life in a disintegrating social order. His Jewish  ancestry and socialist views compelled him to leave Germany upon the  Nazi takeover, and he fled to France (1933) and then to the U.S. (1940),  resettling in Paris in the early 1950s.</p><p>Dobrovsky Vdo-brof-skeV Josef (b.

He was ordained a priest in 1786, but after 1791 noble patronage allowed  him to devote himself to scholarship in Prague. His textual criticism of  the Bible led him to study Old Church Slavonic and then the Slavic lan�  guages as a group. An influential scholar of the Czech language and its  literature, he published such works as History of the Bohemian Language  and Literature (1792). His grammar of Czech, Learning System of the  Bohemian Language (1809), helped standardize literary Czech, and his  grammar of Old Church Slavonic (1822) laid the foundation of compara�  tive Slavic LINGUISTICS.</p><p>dobsonfly Any insect of the family Corydalidae with four net-veined  wings, found in North and South America, Asia, Australia, and Africa.  The species Corydalus cornutus has a wingspread of about 5 in. (13 cm),  and the male has very large jaws (mandibles) of about 1 in. (2.5 cm) or  more. Females lay eggs near streams. Larvae live in the streams and, with  their strong biting mouthparts, are ferocious predators on other aquatic  insects and small invertebrates. Sometimes called hellgrammites or toe-  biters, they can inflict painful bites on humans; they are eaten by fish,  especially bass, and are used as bait by fishermen.</p><p>Dobzhansky \dob-'zhan-ske\, Theodosius orig.

He immigrated in 1927 to the U.S., where he  taught at the California Institute of Technology, Columbia University, and  Rockefeller University. He laid the groundwork for a theory combining  Darwinian evolution and Mendelian genetics by changing the then com�  monly held view that natural selection produced something close to the  best of all possible results and that changes would be rare and slow and  not apparent over one life span. He observed extensive genetic variabil�  ity in wild populations of Drosophila, and he found that in a given popu�  lation some genes would regularly change in abundance with the seasons  of the year.</p><p>dock Any coarse weedy plant of the genus Rumex, in the buckwheat fam�  ily, that has a long taproot and is sometimes used as a potherb.

Under the influence of Classical  rhetoric, late Baroque theorists and composers held that music is capable  of arousing a variety of specific emotions in the listener, and that, by  employing the proper musical procedure or device, the composer could  produce a particular involuntary emotional response in his audience. By  the end of the 17th century, individual movements were customarily orga�  nized around a single emotion, resulting in the lack of strong contrasts  and the repetitive rhythms characteristic of Baroque music. Several  attempts at systematic lists of the emotional effects of different scales and  figures were made, but to no general agreement.</p><p>Doctrine of the Mean See Zhong yong</p><p>rootlike organs called haustoria that penetrate the tissue of a host plant and  may kill it.

Documentaries can deal with scientific or educational topics, can be a  form of journalism or social commentary, or can be a conduit for propa�  ganda or personal expression. The term was first coined by Scottish-bom  filmmaker John Grierson to describe fact-based features such as Robert  Flaherty�s Nanook of the North (1922). Grierson�s Drifters (1929) and  Pare Lorentz�s The Plow That Broke the Plains (1936) influenced docu�  mentary filmmaking in the 1930s. During the World War II era documen�  tary filmmaking was a valuable propaganda tool used by all sides. Leni  Riefenstahl contributed to the Nazi propaganda efforts in the 1930s; the  U.S. made films such as Frank Capra�s series Why We Fight (1942-45);  and Britain released London Can Take It (1940). Cinema verite documen�  taries, which gained notoriety in the 1960s, emphasized a more informal  and intimate relationship between  camera and subject.

Sled dogs are  usually Eskimo dogs, Siberian huskies, Samoyeds, or Alaskan malamutes; teams  typically consist of 4-10 dogs. The course is usually 12-30 mi (19-48 km)  long, though some, including the Iditarod, are considerably longer.</p><p>dogtooth violet Any of the approximately 20 species of spring�  blooming plants that make up the genus Erythronium, in the lily family, all  native to North America except for the purple- or pink-flowered dogtooth  violet of Europe ( E . dens-canis). The nodding flowers, usually one to a</p><p>plant or in small clusters, range in colour from white to purple. The two  leaves, borne at the base of the plant, often are covered with white or  brown spots. The common dogtooth violet of North America, E. ameri-  canum, has yellow flowers and brown-mottled leaves. Several species are  grown as rock-garden ornamentals.</p><p>dogwood Shrubs, trees, and herbaceous plants of the genus Cornus, in  the dogwood family (Cornaceae),  found in temperate and warm tem�  perate zones and on tropical moun�  tains. The family is noted for its  woody ornamental species native to  both coasts of North America and to  eastern Asia and Europe. Some  members, such as the flowering dog�  wood ( Cornus florida), are chiefly  ornamental; the European cornelian  cherry (C. mas), also an ornamental,  has edible fruit; others yield wood  for furniture. In the flowering dog�  woods, flowers are small; the con�  spicuously expanded structures are  coloured bracts that surround the  cluster of true flowers.</p><p>Doha Vdo-hoX Arabic Al-  Dawhah \ad-'dau-h9\ City (pop.,</p><p>1997: 264,009), capital of Qatar.</p><p>Located on the east coast of the  Qatar Peninsula, it contains about three-fifths of the country�s population.  Long a centre of pirate activity in the Persian Gulf, Doha was a small vil�  lage when it became the capital of newly independent Qatar in 1971. The  city has been thoroughly modernized. Its Government House (1969) was  built on reclaimed waterfront land; its water supply is obtained by distill�  ing seawater. The deepwater port, built in the 1970s, accommodates  oceangoing vessels.</p><p>Doherty, Peter Charles (b. Oct. 15, 1940, Australia) Australian  immunologist and pathologist. He earned a Ph.D. at the University of  Edinburgh. With Rolf M. Zinkernagel, he found that T cells from mice  infected with a meningitis virus destroyed virus-infected cells only from  the same strain of mice, and he showed that T cells must recognize two  signals on an infected cell�one from the virus and one from the cell�s  own antigens�to destroy it. For the new understanding of general cel�  lular immune mechanisms enabled by their research, the two men shared  a 1996 Nobel Prize.</p><p>Dole, Bob in full Robert Joseph Dole (b.

Seriously wounded while fighting in World  War II, he recovered from near-total paralysis but permanently lost the  use of his right arm and hand. He returned to Kansas, earned a law degree,  and held state elective office as a Republican before serving in the U.S.  House of Representatives (1961-69) and the Senate (1969-96). He was  the running mate of Pres. Gerald R. Ford in 1976. In 1984 Dole became  Republican Party leader in the Senate, and he twice served as majority  leader (1984-86, 1994-96). After clinching his party�s nomination for  president in 1996, he retired from the Senate to devote himself wholly to  the campaign. He was defeated in the election by Democrat Bill Clinton.  His wife, Elizabeth Hanford Dole (bom 1936), ran unsuccessfully for the  Republican nomination in 2000 but was elected to the U.S. Senate from  North Carolina in 2002.</p><p>Dole, Sanford Ballard (b.

The son of U.S.  missionaries, he served in Hawaii�s legislature (1884-87) and on its  supreme court (1887-93). He led the committee formed by local sugar  interests that overthrew Queen Liliuokalani ( 1 893) and sought annexation  by the U.S.; he then served as the first president of the Republic of Hawaii  (1894-1900). Though U.S. Pres. Grover Cleveland demanded the queen�s  restoration, Dole pressed successfully for annexation (1900) and after�  ward served as governor of the Territory of Hawaii (1900-03).

The doll is perhaps  humankind�s oldest toy. Some  ancient dolls may have served reli�  gious or magical functions�as do  voodoo (see vodun) dolls in modern  times. Dolls were buried in children�s  graves in Egypt, Greece, and Rome  and in early Christian catacombs. In  Europe dolls have been commer�  cially manufactured since about the  16th century. Doll heads were made  of wood, terra-cotta, alabaster, and  wax, while the bodies were made of  carved wood or leather stuffed with  sawdust. In about 1820 glazed porce�  lain (Dresden) doll heads and  unglazed bisque (ceramic) heads  became popular. These were sup�  planted in the 20th century by  molded plastic. In Japan, dolls are  used as traditional festival figures. In  India, elaborately dressed dolls were  given to child brides by both Hindus  and Muslims. Today both antique and  modern dolls are often collected.</p><p>Dollar Diplomacy U.S. foreign  policy created by Pres.

Opposed to the Nazis, he welcomed Benito Mussolini as an ally, convert�  ing Austria virtually into an Italian satellite state. In 1933 he abolished  the parliament and established an authoritarian regime based on conser�  vative Roman Catholic and Italian Fascist principles. In 1934 after para�  military groups loyal to him crushed Austria�s Social Democrats, he  issued a new constitution establishing a dictatorship.

The mountains are formed of light-colored dolomitic limestone,  which erosion has carved into grotesque shapes. Popular with tourists and  mountain-climbers, the area has a number of resort towns.</p><p>dolphin One of a large group of small, gregarious, streamlined whales  or one of two species of oceanic  sport and food fishes. Mammalian  dolphins are small toothed whales,  usually with a well-defined, beaklike  snout. (They are sometimes called  porpoises, but that name is properly  reserved for a blunt-snouted whale  family.) The common dolphin ( Del-  phinus delphis) and the bottlenose  dolphin, both of the family Delphin-  idae, are found widely in warm tem�  perate seas, though some inhabit  tropical rivers. Most of the 32 del-  phinid species are marine; gray,  blackish or brown above and pale  below; and about 3-13 ft (1^1 m)  long. River dolphins (family Pla-  tanistidae; five species) live mainly  in fresh water in South America and  Asia. One of the two fish species,</p><p>Coryphaena hippuras (family Coryphaenidae), also called mahimahi and  dorado, is a popular fish of tropical and temperate waters worldwide.

Domes first appeared on round huts and tombs in  the ancient Middle East, India, and the Mediterranean in forms, such as  solid mounds, adaptable only to the smallest buildings. The Romans intro�  duced the large-scale masonry hemisphere. A dome exerts thrust all around  its perimeter, and the earliest monumental examples (see Pantheon)  required heavy supporting walls. Byzantine architects invented a technique  for raising domes on piers, making the transition from a cubic base to the  hemisphere by four pendentives. Bulbous or pointed domes were widely  used in Islamic architecture. The design spread to Russia, where it gained  great popularity in the form of the onion dome, a pointed, domelike roof  structure. The modern geodesic dome, developed by R. Buckminster Fuller,  is fabricated of lightweight triangular framing that distributes stresses  within the structure itself. See illustration opposite.</p><p>Dome of the Rock or Mosque of Omar Oldest existing Islamic  monument. It is located on Temple Mount, previously the site of the  Temple of Jerusalem. The rock over which it is built is sacred to both Mus�  lims and Jews. In Islam, Muhammad is believed to have ascended into  heaven from the site. In Judaism it is the site where Abraham prepared to  sacrifice his son Isaac. Built in 685-91 as a place of pilgrimage, the  octagonal building has richly decorated walls and a gold-overlaid dome  mounted above a circle of piers and columns.</p><p>Domenichino N.do-ma-ne-'ke-noV orig.

In 1602 he joined the  Bolognese artists in Rome working  under Annibale Carracci in the deco�  ration of the Famese Palace. His  work, done in the Baroque Classical  style, is marked by lucid and bal�  anced compositions, even and serene  lighting and subdued colours, and  the sober expressions and restrained  gestures of its figures. He became  Rome�s leading painter and had a  succession of major decorative com�  missions. He was an outstanding  draftsman and portraitist; his paint�  ings were regarded as second only to  those of I^phael throughout the  17th�18th centuries and had great  influence on Nicolas Poussin and  Claude Lorrain.</p><p>Domenico Veneziano \d6-'ma-  ne-ko-vo-.net-se-'a-noV (b. c. 1410,</p><p>Venice, Republic of Venice�d.

Two signed works survive:  fresco fragments of the Virgin and Child from a street tabernacle (1430s)  and the altarpiece for the church of Santa Lucia dei Magnoli, called the  St. Lucy Altarpiece (c. 1445), one of the outstanding Florentine early  Renaissance paintings of the mid 15th century and Domenico�s most suc�  cessful experiment in rendering outdoor light. He used colour and texture  as the basis of perspective and composition; his influence can be seen in  the work of Alesso Baldovinetti.</p><p>A dome is traditionally supported primarily by a cylindrical or polygonal drum; it  may be surmounted by a cupola, which may have a lantern to admit light.

The most  remarkable administrative feat of the Middle Ages, the survey was carried  out, against popular resentment, by panels of commissioners who compiled  accounts of the estates of the king and his tenants. As summarized in the  Domesday Book, it now serves as the starting point for the history of most  English towns and villages. Originally called �the description of England,�  the name Domesday Book (a reference to doomsday, when people face a  final accounting of their lives) was later popularly attached to it.</p><p>domestic cat or house cat Domesticated carnivore (Felis catus) that  retains many characteristics of the larger wild cats but differs in coat and  size. Breeds are either shorthaired (e.g., Siamese) or longhaired (e.g., Per�  sian). Domestic cats are usually white, black, yellow, or gray and some�  times have markings of a different colour. A pattern of dark stripes or  swirls on a lighter background is called tabby. Males may reach lengths  of 28 in. (71 cm), and females are usually about 20 in. (51 cm) long.  Weights generally vary from 6 to 10 lb (2.5 to 4.5 kg), though nonped-  igreed cats may weigh up to 28 lb (13 kg). The most closely related wild  species are the North African wildcats (including Felix lybica). Valued  for their mouse and rat hunting, which protected farmers� grain supplies,  cats were being domesticated in ancient Egypt by 1500 bc. The Cat Fan�  ciers� Association now recognizes about 37 breeds.</p><p>domestic service Employment of hired workers by private households  for tasks including housecleaning, cooking, child care, gardening, and per�  sonal service. It also includes the performance of similar tasks for hire in  public institutions and businesses, including hotels and boardinghouses. In  ancient Greece and Rome domestic service was performed almost exclu�  sively by slaves. In medieval Europe serfs provided much of the necessary  labour force. Indentured servants were widely used in colonial America, as  were black slaves in the pre-Civil War South. In Victorian England many  middle- and upper-class households hired domestic servants; the royalty  and gentry often employed huge staffs with an elaborate hierarchy.

The domestic system differed from the handicraft  system of home production in that the workers neither bought materials nor  sold products. It undermined the urban guilds and brought the first wide�  spread industrial employment of women and children. The system was  generally superseded by employment in factories but was retained in the  20th century in some industries, notably watchmaking in Switzerland, toy  manufacturing in Germany, and many industries in India and China.</p><p>domestic tragedy Drama in which the main characters are ordinary  people. This form of tragedy contrasts with Classical tragedy, in which  the main characters are of royal or aristocratic rank. An early domestic  tragedy, A Warning for Faire Women (1599), deals with the murder of a  merchant by his wife. The form became popular in the mid-18th century  and reached its maturity in the 19th-century bourgeois tragedies of Hen�  rik Ibsen. Gerhart Hauptmann, Eugene O'Neill, and Arthur Miller wrote  important 20th-century domestic tragedies.</p><p>domestication Process of hereditary reorganization of wild animals  and plants into forms more accommodating to the interests of people. In  its strictest sense, it refers to the initial stage of human mastery of wild  animals and plants. The fundamental distinction of domesticated animals  and plants from their wild ancestors is that they are created by human  labour to meet specific requirements or whims and are adapted to the con�  ditions of continuous care people maintain for them. A variety of animals  have been domesticated for food (e.g., cattle, chickens, pigs), clothing (e.g.,  sheep, silkworms), transportation and labour (e.g., camels, donkeys, horses),  and pleasure (e.g., cats, dogs). See also breeding; selection.</p><p>domicile Place where an individual has a fixed and permanent home for  legal purposes. The term refers to the place where an organization (e.g.,  a corporation) is chartered or that is the organization�s principal place of  business.

Religion: Christianity  (predominantly Roman Catholic; also Protestant). Currency: Eastern Car�  ibbean dollar. A mountainous island, Dominica is broken midway by a  plain drained by the Layou River. It has a warm tropical climate with  heavy rainfall. The main crop is bananas. Dominica is among the poorest  of the Caribbean nations. A developing tourist trade was helped by the  establishment in 1975 of Morne Trois Pi tons National Park, a unique  tropical mountain wilderness, but the country was ravaged by hurricanes  in 1979 and 1980. With financial help from Britain, it is trying to protect  its coastline. It is a republic with one legislative house; its chief of state  is the president, and its head of government is the prime minister. At the  time of Christopher Columbus�s arrival in 1493, it was inhabited by the  Caribs. Because of its steep coastal cliffs and inaccessible mountains, it  remained in the possession of the Caribs until the 18th century; it was  then settled by the French and later taken by Britain in 1783. Subsequent  hostilities between the settlers and the native inhabitants resulted in the  Caribs� near extinction. Incorporated with the Leeward Islands in 1833 and  with the Windward Islands in 1940, it became a member of the West Indies  Federation in 1958. Dominica became independent in 1978.

Area:  18,792 sq mi (48,671 sq km). Population (2005 est.): 8,895,000. Capital:</p><p>Santo Domingo. The majority of the  people are of mixed European-African  ancestry; most of the rest are of European  or African descent. Language: Spanish  (official). Religion: Christianity (predomi�  nantly Roman Catholic; also Protestant). Currency: Dominican peso. The  country is generally mountainous, with ranges and hills running from  northwest to southeast. The Central Highlands reach 10,417 ft (3,175 m)  at Duarte Peak, the highest point in the West Indies. The Cibao Valley in  the north is noted for its fertility; the southwestern part of the country is  generally dry with large stretches of desert. Traditionally dominated by  sugar production, the Dominican Republic�s mixed economy became  increasingly diversified in the late 20th century, when the country expe�  rienced one of the world�s highest economic growth rates, though wide�  spread poverty remained despite a growing middle class. It is a republic  with two legislative houses; its head of state and government is the presi�  dent. The Dominican Republic was originally part of the Spanish colony  of Hispaniola. In 1697 the western third of the island, which later became  Haiti, was ceded to France; the remainder of the island passed to France  in 1795. The eastern two-thirds of the island were returned to Spain in  1809, and the colony declared its independence in 1821. Within a matter  of weeks it was overrun by Haitian troops and occupied until 1844. Since  then the country has been under the rule of a succession of dictators,  except for short interludes of democratic government, and the U.S. has  frequently been involved in its affairs. The termination of the dictatorship  of Rafael Trujillo in 1961 led to civil war in 1965 and U.S. military inter�  vention. For the rest of the country, politics in the Dominican Republic  were dominated by seven-time president Joaquin Balaguer. The country  suffered from severe hurricanes in 1979 and 1998.</p><p>domino theory or domino effect Doctrine of U.S. foreign policy  during the Cold War, according to which the fall of a noncommunist state  to communism would precipitate the fall of other neighbouring noncom�  munist states. The theory was first enunciated by Pres. Harry Truman, who  used it to justify sending U.S. military aid to Greece and Turkey in the  late 1940s. Dwight D. Eisenhower, John F. Kennedy, and Lyndon B. Johnson</p><p>invoked it to justify U.S. military involvement in Southeast Asia, espe�  cially the prosecution of the Vietnam War.</p><p>dominoes Game of several variations played with a set of flat rectan�  gular blocks (dominoes) whose faces are divided into two equal parts that  are blank or bear from one to six dots arranged as on dice faces. The usual  set consists of 28 pieces. Dominoes in China may date to the 12th cen�  tury ad; the Eskimos have also long played a domino-like game. There is  no record of dominoes in Europe before the mid-18th century. The prin�  ciple in nearly all modern dominoes games is to match one end of a piece  to another that is identically or reciprocally numbered. The game may be  set at 50 or 100 points.</p><p>Domitian \do-'mish-3n\ Latin Caesar Domitianus Augustus  orig. Titus Flavius Domitianus (b. Oct. 24, ad 51�d. Sept. 18, 96,  Rome) Roman emperor (81-96). The son of Vespasian, he succeeded his  brother Titus, whom he probably had killed. His administration was osten�  sibly egalitarian and based on precedent, but his laws were severe. Defeats  in Britain and Germany undid his successes, though increased pay for the  army kept it loyal. From 89 he became crueler, imposing a reign of ter�  ror over prominent senators and confiscating his victims� property to  cover imperial expenses. The group that killed him included his wife and  possibly his successor, Nerva.</p><p>domovoy Vds-ms-'voA In Slavic mythology and folklore, a spirit-  guardian of home and family. It never leaves the household to which it  belongs. It favours hardworking people; when displeased with its family,  it may cause trouble with farm animals or make knocking or grating  noises. Its weeping, moaning, or singing are interpreted as portents of evil  or good.</p><p>Don \'don\ In Welsh mythology, a mother-goddess, the counterpart of  the Irish Danu. According to the Mabinogion, she was the sister of the  magician-king Math and the mother of Gwydion (a master of magic and  poetry) and Arianrhod, who was in turn the mother of Dylan (presumed  to be a sea god) and Lieu Llaw Gyffes (probably the Welsh form of Lugus).</p><p>Don Juan Fictional character famous as a heartless womanizer but also  noted for his charm and courage. In Spanish legend, Don Juan was a  licentious rogue who seduced a young girl of noble family and killed her  father. Coming across a stone effigy of the father in a cemetery, he invited  it home to dine with him, and the ghost of the father arrived for dinner  as the harbinger of Don Juan�s death. The legend of Don Juan was first  written down by Tirso de Molina, who gave it an original twist in his trag�  edy The Seducer of Seville (1630). The story was subsequently taken up  by many other artists including W. A. Mozart, in the opera Don Giovanni  (1787); Moliere and George Bernard Shaw, in plays; and Lord Byron in his  long satiric poem Don Juan (1819-24).</p><p>Don Pacifico Affair (1850) Conflict between Britain and Greece that  originated when the home of David Pacifico (known as Don Pacifico), a  British subject living in Athens, was burned down in an anti-Semitic riot.  In support of his demand for compensation, Viscount Palmerston sent a  naval squadron to blockade the Greek coast. Palmerston�s policy drew  protests from France and Russia as well as Britain�s House of Lords, but  he won the support of the Commons after arguing that Britain should pro�  tect its subjects from injustice wherever they might live.</p><p>Don River \'don\ Tatar Duna Vdu-nsX ancient Tanais.

Donato di  Niccolo (b. c. 1386, Florence�d.</p><p>Dec. 13, 1466, Florence) Italian  sculptor active in Florence. He  learned stone carving from the sculp�  tors of the Florence Cathedral (c.</p><p>1400), and in 1404 joined the work�  shop of Lorenzo Ghiberti. He drew his  inspiration from Classical and medi�  eval sources. With his marble statues  of St. Mark (1411-13) and St.</p><p>George (c. 1415) for the church of Or  San Michele in Florence, he revolu�  tionized the concept of sculpture; not  since antiquity had the human body  been rendered with such naturalism  and emotional impact. He invented  his own style of bas-relief with his  marble panel St. George Killing the  Dragon (c. 1417). His bronze sculp�  ture David, conceived independently  of any architectural setting, was the first large-scale, freestanding nude  statue of the Renaissance. In Florence he worked for the Medici family  (1433�43), producing sculptural decoration for the sacristy of San  Lorenzo, the Medici family church, and in Padua (1450s) for the church  of Sant�Antonio. He was the greatest European sculptor of the 15th cen�  tury, influencing painters as well as sculptors, and was a founder of the  Renaissance style.</p><p>Donation of Constantine Document concerning the supposed grant  by the emperor Constantine I (the Great) to Pope Sylvester I (314-335)  and later popes of temporal power over Rome and the Western Empire.  The gift was said to have been motivated by Constantine�s gratitude to  Sylvester for miraculously healing his leprosy and converting him to  Christianity. Based on legends from the 5th century concerning Sylvester  and Constantine, the Donation was probably written at Rome in the mid  8th century and was related to the coronation of Pippin III, the first Caro-  lingian king of the Franks. Proved in the 15th century by Lorenzo Valla to  be a forgery, the document was already questioned by the emperor Otto  III (r. 996-1002) but was often cited in the 11th�15th centuries to support  papal claims in the struggle between church and state.</p><p>Donation of Pippin (754) Promise made by the Frankish king Pippin  III to win for Pope Stephen II Byzantine imperial lands in Italy conquered  by the Lombards. The Donation was made in the context of the papal  struggle with the Lombards, the collapse of Byzantine support for the  papacy, and Pippin�s elevation to the royal throne with papal support. In  756 it was written in a document that became the basis of papal rule over  central Italy, which lasted until the 19th century. Pippin won territory from  the Lombard king in two military campaigns (754, 756) and gave it to the  papacy. The Donation was later confirmed and enlarged by Charlemagne</p><p>(774).</p><p>Donatism Vdo-no-.ti-zom, 'da-no-.ti-zomX Schismatic Christian move�  ment in North Africa in the 4th century. It arose out of the debate over  the status of church leaders who had cooperated with Roman officials  during persecutions of Christians. The movement�s leader, Donatus (died  c. ad 355), denied the validity of priestly duties performed by such lead�  ers, insisting that lapsed Christians were not in a state of grace and thus  had no authority to administer the sacraments. The struggle over the  Donatist heresy came to a head in 311, when Caecilian was consecrated  bishop of Carthage by a lapsed bishop. The Donatists declared the elec�  tion invalid, but Constantine I decided in favor of Caecilian, prompting  the Donatists to break with the Roman church in 312. Despite persecu�  tion, Donatism survived in North Africa until the advent of Islam (7th  century).</p><p>Donbas See Donets Basin</p><p>Donders Vdon-dorzX, Frans Cornells (b. May 27, 1818, Tilburg,  Neth.�d. March 24, 1889, Utrecht) Dutch ophthalmologist. His study of</p><p>�muscae volitantes� (spots before the eyes) resulted in Donders� law, stat�  ing that the rotation of the eye around the line of sight is involuntary. His  research improved diagnosis, operative treatment, and use of eyeglasses  for vision problems. He found that in farsightedness the eyeball is short�  ened, resulting in light rays being focused behind the retina (1858). His  finding that astigmatism is caused by uneven corneal and lens surfaces  (1862) created the field of scientific clinical refraction. His On the Anoma�  lies of Accommodation and Refraction (1864) was the first authoritative  work in the field.</p><p>Donen Vdo-nonX, Stanley (b. April 13, 1924, Columbia, S.C., U.S.)  U.S. film director and choreographer. He began his career in the stage  chorus of Pal Joey (1940), where he met Gene Kelly. He and Kelly cho�  reographed Best Foot Forward (1941 ; film, 1943) and other musicals, and  the two codirected On the Town (1949) and the acclaimed Singin� in the  Rain (1952). Both films showed off Donen�s skill at intensifying a sense  of fantasy and served to reenergize the musical film genre. He later  directed and produced films such as The Pajama Game (1957), Funny  Face (1957), and Damn Yankees (1958). He also branched into nonmu�  sical films such as Charade (1963) and Two for the Road (1967).</p><p>Donets Basin \do-'nyets,\ English Xdo-'netsX or Donbas X'dan-.basX  Large mining and industrial region, southeastern Ukraine and southwest�  ern Russia. Notable for its coal and iron reserves, the exploited area of  the coalfield covers nearly 9,000 sq mi (23,300 sq km) south of the Donets  River. First mined in the early 19th century, by 1913 the Donets Basin was  producing 87% of Russian coal. The coalfields adjoin the rich ironfield  of Krivoi Rog, where an ironworks was set up in 1872 in Donetsk; by  1913 it was making 74% of all Russian pig iron. The area today is the  largest single producing area of iron and steel in Ukraine and one of the  world�s major heavy-industrial complexes.</p><p>Donets River River, southwestern Russia and eastern Ukraine. Rising  in the Central Russian Upland, it winds south and east through Russia  and Ukraine for some 650 mi (1,050 km) to join the Don River below  Konstantinovsk. It flows along the northern Donets Basin industrial region,  which uses it for heavy shipping and also causes severe pollution prob�  lems. A water shortage in the river and industrial area led to the construc�  tion in the 1970s of a canal connecting the Dnieper to the Donets.

In 1872 an ironworks was  founded there by a Welshman, John Hughes, to produce iron rails for the  growing Russian rail network. Fueled by the rich deposits of the Donets  Basin, both coal mining and steelmaking developed rapidly. Extensive  destruction in World War II led to postwar modernization, and subsequent  growth has been rapid.

He is noted especially for  his writings on Chinese painting, which he divided into the Northern  school, which taught the acquisition of truth, and the Southern school,  which emphasized sudden, intuitive understanding. At the centre of the  scholarly ideal of the Southern school was the art of calligraphy, which  expressed the true nature of the artist without the interposition of picto�  rial description. Dong Qichang�s own paintings stress stark forms, seem�  ingly anomalous spatial renderings, and naive handling of ink and brush.  His ideas continue to influence Chinese aesthetic theory.</p><p>Dong Son X'doq-'sonX culture Important prehistoric culture of main�  land Southeast Asia that developed in the 1st millennium bc, best known  for its bronzes. Excavations at the site of Dong Son in northern Vietnam  revealed bronze objects, iron, pottery, and Chinese artifacts. The Dong  Son were a seafaring people who traded throughout Southeast Asia. They  are credited with making the Red River delta area a great rice-growing  region. Dong Son culture, transformed by Chinese and Indian influence,  became the basis of the general civilization of the region.

He established Confucianism as the empire�s  unifying ideology (136 bc) and set up an imperial college, instrumental  in the later establishment of the Chinese civil service. As a philosopher,  he made the theory of the interaction between heaven and humanity his  central theme. He merged the yin-yang concept with Confucianism and  believed that one of the emperor�s duties was to preserve the balance of  yin and yang.

After serving as a submarine officer in World War I, he  oversaw the creation of the German U-boat fleet in the 1930s, thus vio�  lating the Treaty of Versailles. As the fleet�s commander, he conducted the  Battle of the Atlantic in World War II, then served as commander in chief  of the navy (1943�45). He succeeded Adolf Hitler as Germany�s leader  in the last few days of the war and executed Germany�s surrender to the  Allies.

He was tutored and guided by the opera composer  Simone Mayr (1763-1845). His opera Zoraida di Granata had a success�  ful premiere in Rome in 1822, but it was Anna Bolena in 1830 that made  his name internationally. Later successes included L�Elisir d�amore  (1832), Lucrezia Borgia (1833), Lucia di Lammermoor (1835), Roberto  Devereux (1837), La Fille du regiment (1840), and Don Pasquale (1843).  Enormously prolific, he could produce an entire opera in weeks. He com�  pleted almost 70 operas, as well as more than 150 sacred works and hun�  dreds of songs.

Arrested by Ottoman authorities in 1666, he chose conversion  to Islam over death, as did his followers, who believed that his conver�  sion was a step in the fulfillment of messianic prophecy. While accepting  Islam, they secretly practiced various Jewish rites, preserved some knowl�  edge of Hebrew, and refused to intermarry with Muslims.

Early doors were hides or tex�  tiles. With monumental architecture came pivoting doors of rigid, perma�  nent materials; important chambers often had stone or bronze doors.  Pompeiian doors looked much like modem wooden doors; they were  constructed of stiles (vertical planks) and rails (horizontal planks) fastened  together to support panels and occasionally equipped with locks and  hinges. The typical Western medieval door was of vertical planks backed  with horizontal or diagonal bracing. In the 20th century, a single, hollow-  core panel door became most common. Other types include the revolv�  ing door, folding door, sliding door (inspired by the Japanese SHOJl), rolling  door, and Dutch door (divided horizontally so that the lower or upper part  can be opened separately).</p><p>Door Peninsula Peninsula, northeastern Wisconsin, U.S. Located  between Green Bay and Lake Michigan, it was named for a strait at its tip  known as La Porte des Mortes (�Death�s Door�).

He served as lieuten�  ant governor (1766-68) and governor (1768-78) of Quebec province. His  conciliatory policies toward the French Canadians led to passage of the  Quebec Act of 1774. He helped repel the attack on Quebec by American  Revolutionary forces in 1775. He was appointed commander of British  forces in North America in 1782 and then governor in chief of British  North America (1786-96).</p><p>Dordogne River \d6r-'don y \ ancient Duranius.

He achieved fame and wide  popularity with his wood-engraved book illustrations; among the finest  were editions of Dante�s Inferno (1861) and the Bible (1866). His vivid  work is characterized by images of the grotesque and bizarre. Employing  over 40 block cutters, he eventually produced more than 90 illustrated  books.</p><p>Doren, Carl and Mark Van See Carl and Mark Van Doren</p><p>Dorgon Vd6r-,gan\ Chinese Chengzong or Ch'eng-tsung</p><p>Vcheq-'dzurjV (b.

He joined his former enemy Wu Sangui  in driving the Chinese rebel Li Zicheng from Beijing, where Li had already  unseated the last Ming-dynasty emperor. Though some wanted to put Dor�  gon on the throne, he saw to it that his nephew Fu-lin was proclaimed  emperor (Dorgon acted as regent); this loyalty and selflessness won him  the high regard of future historians.</p><p>Doria Vd6r-ya\, Andrea (b.

A member of an  aristocratic family, he was orphaned  at an early age and became a soldier  of fortune. In 1522 he entered the  service of Francis I, who was fight�  ing Emperor Charles V in Italy. Doria  later transferred his services to  Charles and in 1528 drove the  French out of Genoa. He became the  new ruler of Genoa and reorganized  its government into an effective and  stable oligarchy. He commanded  several naval expeditions against the  Turks and helped Charles V extend  his domination over the Italian pen�  insula.

They had their own dialect and were organized  into three tribes. Patterns of settlement determined their alliances in later  Greek conflicts. To Greek culture they gave the Doric order of architec�  ture, the tragic choral lyric, and a militarized aristocratic government.  They assimilated into Greek societies in some cases, but in Sparta and  Crete they held power and resisted cultural advancement.</p><p>Andrea Doria, detail of a portrait by  Sebastiano del Piombo; in the Doria  Palace, Rome.</p><p>AUNARI/ART RESOURCE, NEW VORK</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>566 I dormer &#x25BA; double-aspect theory</p><p>dormer Window set vertically in a structure that projects from a slop�  ing roof.

After moving to Chi�  cago in 1916, he appeared under the name of �Georgia Tom,� became a  pianist with Ma Rainey, and composed secular �hokum� songs (those pep�  pered with risque double entendres). He wrote his first gospel song in  1919, and in 1932 he abandoned the blues completely and founded the  Pilgrim Baptist Church in Chicago. His more than 1,000 gospel songs  include �Precious Lord, Take My Hand,� �Peace in the Valley,� and �If  We Ever Needed the Lord Before.� He recorded extensively in the early  1930s. Many of his songs were introduced by Mahalia Jackson. He  founded and directed the National Convention of Gospel Choirs and Cho�  ruses.</p><p>Dorsey, Tommy orig. Thomas Dorsey (b.

Dorsey led the Dorsey Brothers Orchestra from 1934  with his brother, saxophonist and clarinetist Jimmy Dorsey (1904-57);  they later separated to lead their own groups. Tommy Dorsey�s band  combined smooth ballad performances with up-tempo jazz arrangements  featuring some of the best musicians of the period, including Buddy Rich,</p><p>Frank Sinatra, and arranger Sy Oliver. Dorsey�s trombone playing was  technically impeccable, and his seamless phrasing and sweet tone were a  major influence on singers and brass players alike.

A prosperous trading centre in the 14th century, it  declined after the Thirty Years' War and lost its imperial rights in 1803.  The development of coal and iron ore mining and the completion of the  Dortmund-Ems Canal in 1899 stimulated its regrowth. The city was  largely destroyed in World War II but was extensively rebuilt.

Son of a  wealthy lawyer, Dos Passos attended Harvard University. His wartime  service as an ambulance driver and later work as a journalist led him to  see the U.S. as �two nations,� one for the rich and one for the poor. His  reputation as social historian, radical critic of American life, and major  novelist of the postwar �lost generation� rests primarily on his powerful  U.S.A. trilogy, comprising The 42nd Parallel (1930), 1919 (1932), and  The Big Money (1936).</p><p>Dostoyevsky \das-to-'yef-ske\, Fyodor (Mikhaylovich) (b. Nov.  11, 1821, Moscow, Russia�d. Feb. 9, 1881, St. Petersburg) Russian nov�  elist. Dostoyevsky gave up an engineering career early in order to write.  In 1849 he was arrested for belonging to a radical discussion group; sen�  tenced to be shot, he was reprieved at the last moment and spent four  years at hard labour in Siberia, where he developed epilepsy and expe�  rienced a deepening of his religious faith. Later he published and wrote  for several periodicals while producing his best novels. His novels are  concerned especially with faith, suffering, and the meaning of life; they  are famous for their psychological depth and insight and their near-  prophetic treatment of issues in philosophy and politics. His first, Poor  Folk (1846), was followed the same year by The Double. The House of  the Dead (1862) is based on his imprisonment and The Gambler (1866)  on his own gambling addiction. Best known are the novella Notes from  the Underground (1864) and the great novels Crime and Punishment  (1866), The Idiot (1869), The Possessed (1872), and The Brothers Kara�  mazov (1880), which focuses on the problem of evil, the nature of free�  dom, and the characters� craving for some kind of faith. By the end of  his life, he had been acclaimed one of his country�s greatest writers, and  his works had a profound influence on 20th-century literature.</p><p>Dou Vdau\, Gerrit or Gerard Dou (b.

From 1628 to 1631 he  studied with Rembrandt, adopting his subject matter, careful draftsman�  ship, and dramatic treatment of light and shadow. When Rembrandt left  Leiden, Dou developed his own style, painting smooth, meticulously  detailed, small-scale domestic interiors and portraits. He used the �frame  within a frame� device of surrounding his figures by a window or curtain  and excelled at scenes lit by candlelight. With Jan Steen he was among  the founders of the Guild of St. Luke at Leiden (1648).</p><p>Douala \dii-'a-la\ City (pop., 1992 est.: 1,200,000), chief port of Cam�  eroon, on the Bight of Biafra.

Cameroon�s largest city, it is one of Central Africa�s major industrial cen�  tres, and its deepwater port handles most of the country�s overseas trade.  It is home to a variety of commercial, agricultural, and industrial schools;  a museum and handicraft centre encourage the production and preserva�  tion of Cameroonian art.</p><p>double-aspect theory or dual-aspect theory Type of mind-  body monism. According to double-aspect theory, the mental and the mate�  rial are different aspects or attributes of a unitary reality, which itself is  neither mental nor material.

It var�  ies in size, up to 80 inches (200 cm) tall. Its shape also varies; its shoul�  ders usually slope more than those of the violin, reflecting its status as a  hybrid of the viol and violin families (the name comes from the double-  bass viol). It emerged from these families in the late Renaissance, and it  has always been less standardized in form than its cousins in the violin  family. It normally has four strings; the orchestral instrument often has a  lower fifth string (more often, an extension is added to the fourth string),  and the jazz instrument has a higher fifth string. Its range is an octave  below that of the cello. It is normally bowed in orchestral music and  plucked in jazz. In rock bands and some jazz bands, the electric bass is  used instead.</p><p>double jeopardy In law, the prosecution of a person for an offense  for which he or she already has been prosecuted. In U.S. law, double  jeopardy is prohibited by the 5th Amendment to the Constitution of the  United States, which states that no person shall �be subject for the same  offense to be twice put in jeopardy of life and limb.� The clause bars sec�  ond prosecutions after acquittal or conviction and prohibits multiple con�  victions for the same offense. Thus a person cannot be guilty of both  murder and manslaughter for the same homicide, nor can a person be  retried for the same crime after the case has been resolved. A person can,  however, be convicted of both murder and robbery if the murder arose  from the robbery. The prohibition against double jeopardy is not violated  when an individual is charged for behaviour stemming from an offense  for which he has been charged in a different jurisdiction or in a different  court (e.g., a civil court as opposed to a criminal court). See also rights  of the accused; due process.</p><p>double refraction or birefringence Optical property in which a  single ray of unpolarized light (see polarization) splits into two compo�  nents traveling at different velocities and in different directions. One ray  is refracted (see refraction) at an angle as it travels through the medium,  while the other passes through unchanged. The splitting occurs because  the speed of the ray through the medium is determined by the orientation  of the light compared with the crystal lattice of the medium. Since unpo�  larized light consists of waves that vibrate in all directions, some will pass  through the lattice without being affected, while others will be refracted  and change direction. Materials that exhibit double refraction include ice,  quartz, and sugar.</p><p>double vision or diplopia Perception of two images of an object,  usually caused by temporary or permanent eye-muscle paralysis. Nor�  mally, the brain fuses slightly different images from each eye by matching  corresponding points on each retina. When an eye muscle is paralyzed, the  image falls at a different point and the images do not correspond. Double  vision may be an early symptom of botulism or myasthenia gravis and occurs  in other infections, head injuries, and nerve or muscle disorders.</p><p>Doubleday, Abner (b.

Spalding con�  cluded that Doubleday formulated  the essential rules of baseball in 1839  at Cooperstown, N.Y., leading to the  choice of Cooperstown as the site of  the Baseball Hall of Fame.

In his magazine illus�  trations and murals, he synthesized Cubist forms with stylized and geo�  metric shapes drawn from African art. Perhaps his most significant work  was a series of four murals, collectively titled Aspects of Negro Life, for  the 135th Street branch of the New York Public Library.

He was elected to  the U.S. House of Representatives (1843-47) and Senate (1847-61),  where he strongly supported the Union and national expansion. To settle  the bitter dispute over the extension of slavery to the territories, he devel�  oped the policy of popular sovereignty. He was influential in the passage  of the Compromise of 1850 and the Kansas-Nebraska Act. Short and heavy-  set, he was dubbed �the Little Giant� for his oratorical skill. In 1858 he  engaged in a number of widely publicized debates with Abraham Lincoln  in a close contest for the Senate seat in Illinois (see Lincoln-Douglas  Debates). The Democrats nominated Douglas for president in 1860, but a  splinter group of Southerners nominated John C. Breckinridge, which  divided the Democratic vote and gave the presidency to Lincoln. In 1861  he undertook a mission for Lincoln to gain support for the Union among  the Southern border states and in the Northwest. His untimely death of  typhoid was partly a result of these exertions.</p><p>Douglas, Tommy orig. Thomas Clement Douglas (b. Oct. 20,  1904, Falkirk, Stirlingshire, Scot.�d.

An ordained minister, he became active in the socialist Co-operative  Commonwealth Federation, and he served in the Canadian Parliament  (1935-44). As premier of Saskatchewan (1944-61), he led Canada�s first  socialist government. He established a system of state-run health care in  the province, the first such system in the nation; for this he is considered  the father of socialized medicine in Canada.

U.S. abolitionist. The son of a slave mother and a white  father, he was sent to work as a house servant in Baltimore, where he  learned to read. At age 16 he was returned to the plantation; later he was  hired out as a ship caulker. In 1838 he fled to New York City and then to  New Bedford, Mass., changing his name to elude slave hunters. His elo�  quence at an 1841 antislavery convention propelled him into a new career  as an agent for the Massachusetts Anti-Slavery Society, in which capac�  ity he endured frequent insults and violent personal attacks. In 1845 he  wrote his autobiography, now regarded as a classic. To avoid recapture  by his owner, whose name he had given in the narrative, he embarked on  a speaking tour of England and Ireland (1845�47), returning with enough  money to buy his freedom and to start an antislavery newspaper North  Star , which he published until 1860 in Rochester, N.Y. In 1851 he split  with the radical abolitionist William Lloyd Garrison and allied himself with  moderates led by James Birney. In the American Civil War he was a con�  sultant to Pres. Abraham Lincoln. During Reconstruction he fought for full  civil rights for freedmen and supported women�s rights. He served in  government posts in Washington, D.C.

In World War I his  criticism of the war�s conduct led to his court-martial, imprisonment, and</p><p>retirement. An investigation in 1917 justified his criticisms; his convic�  tion was reversed, and he was appointed head of the aviation service. In  books such as The Command of the Air (1921) he advanced his ideas on  strategic air power and the importance of strategic bombing. He advo�  cated the creation of an independent air force, reduction of land and sea  forces, and unification of the armed forces.

In  the early 20th century they clashed repeatedly with the Canadian gov�  ernment over noncompliance with land, tax, and education laws.

It has extensive barge traffic  in its Portuguese section, and has been harnessed for hydroelectric power.</p><p>dove Any of certain birds of the pigeon family (Columbidae). The names  pigeon and dove are often used interchangeably. Though �dove� usually  refers to the smaller, long-tailed members of the pigeon family, there are  exceptions: the common street pigeon, generally typical for birds desig�  nated as pigeons, is frequently called the rock dove. The common names  of these birds do not necessarily reflect their accurate biological relation�  ships to one another.</p><p>Dove, Rita (Frances) (b.

Laid out in 1717 as the site for a county courthouse and jail  by order of William Penn and named for Dover, Eng., it became the capi�  tal in 1777. Its many colonial buildings include the Old State House  (rebuilt 1787-92), which served as the capitol building until 1933; dis�  played there are King Charles II�s original royal grant and Penn�s deeds  to Delaware (1682). The modern city is a farm trade centre and shipping  point for fruits, and it has some light industries.</p><p>Dover ancient Dubris Portus Town (pop., 1995 est.: 34,000) and  seaport on the Strait of Dover, Dover district, administrative and historic  county of Kent, southeastern England. A pre-Roman settlement existed on  the site, and in the 4th century ad it was guarded by a Saxon fort. During  the 11th century it was chief of the Cinque Ports. Dover Castle, a strong�  hold of medieval England, was besieged by rebellious barons in 1216.  The town was held by Parliamentarians in the English Civil Wars.

After attending college in Cleveland, Dow developed and patented elec�  trolytic methods (the Dow process) for extracting bromine from brines  (concentrated water solutions of salts). In 1895 he founded the Dow Chemi�  cal Co. to electrolyze brine for chlorine, used in insecticides. He was the  first U.S. producer of iodine (which he also extracted from brine). He  eventually was granted some 65 patents as his company became one of  the world�s leading chemical manufacturers.</p><p>Dow Chemical Co, Leading U.S. petrochemical company that manu�  factures chemicals, pharmaceuticals, consumer goods, paint, and many  other products for industrial and home use.

Educated at Oxford, he was  refused a court position in 1594 and, believing his adoptive Catholicism  had been the cause, he left for the continent. There he traveled exten�  sively and took a position at the Danish court. In 1612, when his com�  positions had made him famous, he was finally appointed lutenist to the  English court. He published three collections of songs, including about  90 works for solo lute and some 80 lute songs, including �Come again,  sweet love does now endite,� � Flow my tears,� and �Weep you no more,  sad fountains.� His Lachrimae is a collection for viol-and-lute ensemble.</p><p>Down District (pop., 1999 est.: 63,800), Northern Ireland. Formerly part  of County Down, it was established as a district in 1973. It fronts Strang-  ford Lough and the Irish Sea. Extreme southern and western Down is  mountainous; the dome-shaped Mourne Mountains reach an elevation of  2,789 ft (850 m). Down is a rich agricultural district; livestock raising is  important. Down was settled in prehistoric times. It was where St. Patrick  began his mission in Ireland (ad 432), and his well and bathhouses are  preserved near the district seat, Downpatrick. In Tudor times, parts of  Down were colonized by English and Scottish adventurers.</p><p>Down syndrome or trisomy Vtrl-.so-meN 21 Congenital disorder  caused by an extra chromosome (trisomy) on the chromosome 21 pair.  Those with the syndrome may have broad, flat faces; up-slanted eyes,  sometimes with epicanthal folds (whence its former name, mongolism);  mental retardation (usually moderate); heart or kidney malformations; and  abnormal fingerprint patterns. Many persons with Down syndrome can  live and work independently or in a sheltered environment, but they age  prematurely and have a short (55-year) life expectancy. The risk of bear�  ing a child with the disorder increases with the mother�s age; it can be  detected in the fetus by amniocentesis.</p><p>Downing, Andrew Jackson (b. Oct. 30, 1815, Newburgh, N.Y.,  U.S.�d. July 28, 1852, vicinity of Yonkers, N.Y.) U.S. horticulturist,  landscape gardener, and architect. He educated himself in landscape gar�  dening and architecture while working in his father�s nursery. In 1850 he  began collaborating with the British architect Calvert Vaux (1824-95);  the two designed a number of estates in New York�s Hudson River val�  ley and on Long Island. Recognized as the foremost U.S. landscape  designer of his day, he was commissioned in 1851 to lay out the grounds  for the Capitol, the White House, and the Smithsonian Institution. His  death at 36 in a steamboat accident prevented him from seeing his plans  to completion. His books on architecture and landscaping became stan�  dard works, and his influence on American conceptions of the middle-  class home were far-reaching.</p><p>Downpatrick Town (pop., 1991: 10,113), seat of Down district. North�  ern Ireland. It is on the southwestern end of Strangford Lough. Formerly  a MacDunleary stronghold, it was seized in 1177 by the Anglo-Norman  adventurer John de Courci and served as his headquarters until 1203. St.  Patrick is reputedly buried on the grounds of its cathedral.</p><p>dowry Vdaii-re\ Money, goods, or estate that a woman brings to her  husband in marriage. The dowry has a long history in Europe, South Asia,  Africa, and other parts of the world. Some of its basic functions are to  protect the wife against ill treatment by her husband, since a dowry can  be a conditional gift; to help the husband discharge the responsibilities of  marriage, since the dowry makes it possible for the young man to estab�  lish a household; to provide the wife with support in case of her husband�s  death; and to compensate the groom�s kin for their payment of bridewealth.  In Europe, the dowry served to build the power and wealth of great fami�  lies and played a role in the politics of grand alliance through marriage.  The giving of a dowry more or less disappeared in Europe in the 19th and  20th centuries. The practice grew, however, in South Asia. In some cases,  delayed or insufficient dowry made some young wives the victims of  murder by their husbands or in-laws, a practice known as �bride burning�  or �dowry death.�</p><p>dowsing Vdau-zh]\ Occult practice used for finding water, minerals, or  other hidden substances. A dowser generally uses a Y-shaped piece of  hazel, rowan, or willow wood (also called a dowser or a divining rod).  The dowser grasps the rod by its two prongs and appears, while walking,  to be receiving transmissions from beneath the earth. If the rod quivers  violently or points downward, some buried substance has been located.  First practiced in Europe during the Middle Ages, dowsing is most often  used to find water but may also be employed to locate precious metals,  buried treasure, archaeological remains, or even dead bodies.</p><p>Doyle, Arthur Conan See Sir Arthur Conan Doyle</p><p>Draa \'dra\ River River, southwestern Morocco.

About 100 people (mostly rioters) died.</p><p>drafting Precise graphical representation of a structure, machine, or its  component parts that communicates the intent of a technical design to the  fabricator (or the prospective buyer) of the product. Drawings may present  the various aspects of an object�s form, show the object projected in space,  or explain how it is built. Drafting uses orthographic projection, in which  the object is viewed along parallel lines that are perpendicular to the plane  of the drawing. Orthographic drawings include top views (plans), flat front  and side views (elevations), and cross-sectional views showing profile.  Perspective drawing, which presents a realistic illusion of space, uses a  horizon line and vanishing points to show how objects and spatial rela�  tionships might appear to the eye, including diminution of size and con�  vergence of parallel lines. Drafting was done with precision instruments  (T square or parallel rule, triangle, mechanical pens and pencils) until  computerization revolutionized production methods in architectural and  engineering offices.</p><p>drafting See drawing</p><p>drag Force exerted by a fluid stream on any obstacle in its path or felt  by an object moving through a fluid. Its magnitude and how it may be  reduced are important to designers of moving vehicles, ships, suspension  bridges, cooling towers, and other structures. Drag forces are convention�  ally described by a drag coefficient, defined irrespective of the shape of  the body. Dimensional analysis reveals that the drag coefficient depends on  the Reynolds number; the precise dependence must be elucidated experi�  mentally and can be used to predict the drag forces experienced by other  bodies in other fluids at other velocities. Engineers use this principle of  dynamic similarity when they apply results obtained with a model struc�  ture to predict the behaviour of other structures.

Winners go on to compete against others in their class until only  one is left undefeated. There are three main classes of vehicle: (1) the Top  Fuel Eliminator (called a �rail� or �slingshot�), a lightweight, long-  chassied vehicle with wide rear tires that is fueled by a special mixture,  such as methanol and nitromethane; (2) the �funny car,� a high-  performance copy of a late-model production car that uses special fuel;  and (3) the standard production car, a modified version of a gasoline-  powered production car. The Top Fuel class is the fastest, followed by the  funny car. Drag racing is most popular in the U.S.</p><p>dragon Legendary monster usually depicted as a huge, bat-winged,  fire-breathing lizard or snake with a barbed tail. The dragon symbolized  evil in the ancient Middle East, and the Egyptian god Apepi was the great  serpent of the world of darkness. The Greeks and Romans sometimes rep�  resented dragons as evil creatures and sometimes as beneficent powers  acquainted with the secrets of the earth. In Christianity the dragon sym�  bolized sin and paganism, and saints such as St. George were shown tri�  umphing over it. Used as warlike emblems in many cultures, dragons were  carved on the prows of Norse ships and depicted on royal ensigns in  medieval England. In the Far East the dragon was a beneficent creature,  wingless but regarded as a power of the air. In China it symbolized yang  in the yin-yang of cosmology, and it served as the emblem of the royal  family.</p><p>dragon worm See guinea worm</p><p>dragonfly Any member of the insect suborder Anisoptera (order Odo-  nata), characterized by four large,  membranous, many-veined wings,  that, when at rest, are held horizon�  tally rather than vertically (see dam-  selfly). Dragonflies are agile and have  bulging eyes that often occupy most  of the head and a wingspan of about 6  in. (16 cm). The dragonfly is one of  the fastest-flying and most preda�  ceous insects; in 30 minutes it can eat  its own weight in food. Dragonflies  differ from most other insects by hav�  ing the male copulatory organs at the  front part of the abdomen rather than  at the back end. Male and female often fly in tandem during sperm transfer.</p><p>dragoon In late 16th-century Europe, a mounted soldier who fought as  a light cavalryman on attack and as a dismounted infantryman on defense.  The term derived from his weapon, a short musket called the dragoon.  Dragoons were organized in companies, and their officers bore infantry  titles. By the 18th century, dragoon referred to members of certain cav�  alry regiments. The term is still applied in the British Army to certain  armoured reconnaissance units.</p><p>Drake, Sir Francis (b. c. 1540-43, Devonshire, Eng.�d.

He gained a reputation as an  outstanding navigator and became  wealthy by raiding and plundering  Spanish colonies. In 1577 he set sail  with five ships, but ultimately only  his flagship, the Golden Hind, made  its way through the Strait of Magel�  lan into the Pacific and up the coast  of South and North America. He  sailed at least as far north as what is  now San Francisco, claiming the  area for Elizabeth, and continued  westward to the Philippines and  around the Cape of Good Hope.</p><p>Having circumnavigated the globe, he returned to Plymouth, Eng., in 1580  laden with treasure, the first captain ever to sail his own ship around the  world. In 1581 he was knighted. Appointed vice admiral (1588), he  destroyed ships and supplies destined for the Spanish Armada and delayed  the Spanish attack for a year. But he is not known to have played any part  in the battle that eventually occurred. In his lifetime, his reputation at  home was equivocal, yet his legend grew. On his last voyage he suc�  cumbed to fever and was buried at sea.</p><p>Drake equation or Green Bank equation Equation claimed to  yield the number of technically advanced civilizations capable of inter�  stellar communication in the Milky Way Galaxy as a function of several  factors conducive to evolution of intelligent life with technological capa�  bilities. It was largely developed by Frank D. Drake (b. 1930) in 1961 at  a SETI conference in Green Bank, W.Va. Of all the stars that form in the  Galaxy, only some will give rise to life-supporting planets, and of those  planets, only some will generate life capable of high technology and yet  able to avoid technological destruction. Because the numbers for each  factor are poorly known, the results generated vary from zero to millions.</p><p>Drake Passage Strait, connecting the Atlantic and Pacific oceans  between Tierra del Fuego and the South Shetland Islands.

The four major Dravidian languages of southern India� Telugu,  Tamil, Kannada, and Malayalam �have independent scripts and long docu�  mented histories. They account for the overwhelming majority of all  Dravidian-speakers, and they form the basis of the linguistic states of  Andhra Pradesh, Tamil Nadu, Karnataka, and Kerala. All have borrowed  liberally from Sanskrit. The only Dravidian language spoken entirely out�  side of India is Brahui, with fewer than two million speakers mainly in  Pakistan and Afghanistan. Of the Dravidian languages, Tamil has the  greatest geographical extension and the richest and most ancient litera�  ture, which is paralleled in India only by that of Sanskrit. The Dravidian  family, with no demonstrated relationship to other language families, is  assumed to have covered a much more extensive area of South Asia before  the spread of Indo-Aryan and was the source of loanwords into early  Indo-Aryan dialects.</p><p>drawing Art or technique of producing images on a surface, usually  paper, by means of marks in graphite, ink, chalk, charcoal, or crayon. It  is often a preliminary stage to work in other media. According to Gior�  gio Vasari, disegno (drawing and design) was the foundation of the three  arts of painting, sculpture, and architecture. Beginning in the Italian  Renaissance, debate arose regarding the role of drawing, as some saw it  as an independent art form and others saw it as a preliminary stage in  creating a painting or sculpture. By the 17th century, drawings had defi�  nite market value; connoisseurs specialized in collecting them, and forg�  ers began to exploit the demand. In the 20th century, the drawing became  fully autonomous as an art form, figuring significantly among the works  of virtually every major artist, and the line itself was exploited both for  its representational and its purely expressive qualities.</p><p>drawing or drafting In yarn manufacture, process of attenuating a  loose assemblage of fibres. These fibres, called sliver, pass through a series  of rollers, which straighten the individual fibres and make them more par�  allel. Each pair of rollers spins faster than the previous one. Drawing  reduces a soft mass of fibres to a firm uniform strand of usable size. For  synthetic fibres, drawing is a stretching process applied to fibres in the plas�  tic state, increasing orientation and reducing size. In metalworking, draw�  ing refers to the process of shaping sheet metal into complex, three-  dimensional forms with metal dies. See also carding, wire drawing.</p><p>drawing frame or spinning frame Machine for drawing, twisting,  and winding yarn.

It was equipped entirely with big guns because recent  improvements in naval gunnery had made preparation for short-range  battle unnecessary. Powered by steam turbines instead of the steam pis�  tons then common, it sailed at a record top speed of 21 knots. It displaced  18,000 tons (16,300 metric tons), was 526 ft (160 m) long, and carried a  crew of about 800. By World War I it was nearly outclassed by faster  �superdreadnoughts� carrying bigger guns. It was placed on reserve in  1919 and broken up for scrap in 1923.</p><p>dream Series of thoughts, images, or emotions occurring during sleep,  particularly sleep accompanied by rapid eye movement (REM sleep).  Dream reports range from the very ordinary and realistic to the fantastic  and surreal. Humans have always attached great importance to dreams,  which have been variously viewed as windows to the sacred, the past and  the future, or the world of the dead. Dreams have provided creative solu�  tions to intellectual and emotional problems and have offered ideas for  artistic pursuits. A type of cognitive synthesis that facilitates conscious  insight may occur subconsciously during dreaming. The most famous  theory of the significance of dreams is the psychoanalytic model of Sig�  mund Freud; in Freud�s view, desires that are ordinarily repressed (hidden  from consciousness) because they represent forbidden impulses are given  expression in dreams, though often in disguised (i.e., symbolic) form.</p><p>Dreaming, the or Dream-Time In the religion of the Australian  Aborigines, the mythological time of the Creation. In the Dreaming the  environment was shaped and humanized by mythic beings, many of whom  took animal or human form. Some could change form at will. They took  long journeys and created human life and the social order. In Aboriginal  belief, these beings are eternal and continue to exist, although they may  have traveled beyond the lands of the people who sing about them or may  have metamorphosed into natural features such as rocky outcrops or water  holes. The landscape is thus sacred to Aboriginal peoples. See also Aus�  tralian RELIGION.</p><p>Dred Scott decision formally Dred Scott v.

Scott was a slave whose master had taken him in 1834  from a slave state (Missouri) to a free state and a free territory, then back  to Missouri. Scott sued for his freedom in Missouri in 1846, claiming his  residence in a free state and a free territory made him free. The opinion  of Chief Justice Roger B. Taney declared that Scott was not entitled to  rights as a U.S. citizen and, in fact, had �no rights which any white man  was bound to respect�. Taney and six other justices struck down the Mis�  souri Compromise as unconstitutional, maintaining that Congress had no  power to prohibit slavery in the territories (see states' rights). The deci�  sion, a clear victory for the South, increased Northern antislavery senti�  ment, strengthened the new Republican Party, and fed the sectional strife  that led to war in 1861.</p><p>Dreikaiserbund See Three Emper�  ors' League</p><p>Dreiser VdrI-zoiA, Theodore  (Herman Albert) (b.

Originally a Slavonic settlement, it was the residence of the  margraves of Meissen in the early 13th century. The Dresden china indus�  try originated there but was moved to Meissen in 1710 (see Meissen por�  celain). Napoleon I made Dresden a centre of military operations and won  his last great battle there in 1813. Dresden was occupied by Prussia in  1866. In World War II, it was severely damaged by Allied bombing raids  in 1945. Several of its historic buildings have been restored or recon�  structed. It is known for its art galleries, museums, and other cultural  institutions. Industries produce precision and optical instruments.</p><p>Dresden Codex Latin Codex Dresdensis One of the few pre-  Columbian Maya codices to survive book burnings by Spanish clergy. It  contains exceptionally accurate astronomical calculations, including  ECUPSE-prediction tables and the synodic period of Venus.

The  term encompasses garments as shirts, togas, footwear, hats, and gloves;  hairstyles, facial hair, and wigs; and cosmetics, jewelry, and other forms of  body decoration. In cultures thoughout the world, perhaps the most obvi�  ous function of dress is to provide warmth and protection, but it can also  serve religious or ritual purposes. Other basic functions of dress include  identifying the wearer (by providing information about sex, age, occupa�  tion, or other characteristic) and making the wearer appear more attrac�  tive. In the West up through the modern era, dress has often functioned  as a reflection of social and economic standing.

Particularly important are the  animal�s pace and bearing in performing walks, trots, canters, and more  specialized maneuvers. Training is divided into the elementary campagne  and the advanced haute ecole. Dressage competitions have been included  in the Olympic Games since 1912. Riders compete as individuals and in  teams.</p><p>Dressier, Marie orig. Leila Marie Koerber (b. Nov. 9, 1868,  Cobourg, Ont., Can.�d.

In 1844 he founded the Wall  Street brokerage firm of Drew, Robinson, and Co., which became one of  the principal traders in railroad stocks in the U.S. The �Erie War� of  1866-68, in which Drew joined Jay Gould and James Fisk against Corne�  lius Vanderbilt in a struggle for control of the Erie Railroad Co., eventually  led to his ruin, and he filed for bankruptcy in 1876.</p><p>Drew family U.S. theatrical family. Louisa Lane (later Louisa Lane  Drew; 1820-97) began her stage career at age eight in Philadelphia, where  her widowed mother had brought her from England. Her many success�  ful parts included Lady Teazle, Mrs. Malaprop, and such �breeches� roles  as Shakespeare�s Romeo and Mark Antony. In 1850 she married the Irish  comic actor John Drew (1827-62), who made his U.S. debut in 1842 and  comanaged the Arch Street Theatre in Philadelphia. He toured widely, and</p><p>she managed the theatre from 1861, directing the renamed Mrs. John  Drew�s Arch Street Theatre company with notable success until 1892.  Their son John Drew, Jr. (1853-1927), made his debut (1873) with his  mother�s company, then joined the companies of Augustin Daly (1838�  99) and Charles Frohman (1860-1915). He was noted for his roles in  Shakespearean comedies, society dramas, and light comedies. Their  daughter Georgiana Emma Drew (1854-93) made her acting debut with  her mother�s company (1872). She became the wife of the actor Maurice  Barrymore and the mother of the actors Lionel, Ethel, and John Barry�  more (see Barrymore family).</p><p>Drexel, Anthony J(oseph) (b.

Drexel, she inherited a vast fortune, which she used to fund  her charitable enterprises, including mission schools in Minnesota, South  Dakota, Wyoming, and New Mexico. In 1887 Pope Leo XIII (1878-1903)  asked her to become a missionary. In 1891 she founded the Blessed Sac�  rament Sisters for Indians and Colored People (now Sisters of the Blessed  Sacrament), a congregation of missionary nuns dedicated to the welfare  of Native Americans and African Americans. She also founded several  schools for minority students as well as Xavier University in New Orleans  (1915).

Son of a Jewish textile  manufacturer, he studied at the Ecole  Poly technique, then entered the army  and rose to the rank of captain  (1889). He was assigned to the war  ministry when, in 1894, he was  accused of selling military secrets to  Germany. He was convicted and sen�  tenced to life imprisonment on Dev�  il�s Island. The legal proceedings,  based on insufficient evidence, were  highly irregular, but public opinion  and the French press, led by its viru�  lently anti-Semitic section, wel�  comed the verdict. Doubts began to  grow as evidence came out suggest�  ing that C. F. Esterhazy (1847-1923)  was the true traitor. The movement</p><p>for revision of Dreyfus�s trial gained momentum when Emile Zola wrote an  open letter under the headline �J�Accuse,� accusing the army of covering</p><p>n v</p><p>Alfred Dreyfus, before</p><p>H.

Bell Telephone Labora�  tories hired him to design a series of telephones in the 1930s. Among his  other notable designs was the interior of the ocean liner Independence. A  pioneer of ergonomic design, he published several books explaining his  methods, including Designing for People (1955, 1967).</p><p>drill Large, short-tailed monkey {Mandrillus leucophaeus, family Cerco-  pithecidae). Formerly found from  Nigeria to Cameroon, it is now  restricted to remote forest regions of  Cameroon because of hunting and  deforestation. Like the related man�  drill, the drill is stout-bodied and has  vividly coloured buttocks. The male  is about 32 in. (82 cm) long and has  a black face. Its lower lip is bright  red, the hairs around the face and a  tuft behind the ears are yellowish  white, and the rest of the fur is olive-  brown. An omnivore, it is mainly ter�  restrial, gregarious, and powerful,  and it can fight ferociously if  molested.</p><p>drill Tool to make holes, usually by  revolving. Drills, gimlets, and augers  have cutting edges that detach mate�  rial to leave a hole. Drilling usually  requires high speed and low torque, with little material being removed  during each revolution of the tool. The earliest (perhaps Bronze Age) drill  points had sharp edges that ultimately developed into arrow shapes with  two distinct cutting edges. This shape was effective and remained popu�  lar until the late 19th century, when factory-made, spiral-fluted twist drills  became available at reasonable cost to displace the blacksmith-made  articles. Rotating drill bits containing diamonds or other hard materials  are used for drilling rock, as for tunnels or oil wells. See also drill press.</p><p>drill In military science, the preparation of soldiers for performance of  their duties through the practice of prescribed movements. It trains sol�  diers in battle formations, familiarizes them with their weapons, and  develops a sense of teamwork and discipline. Today close-order drill is  used for marching, ceremonies, and parades; combat drill is used to prac�  tice the looser routines of battle. It was introduced by the Greeks, who  practiced the maneuvers of the phalanx. Careful training of the legions was  a major factor in the Roman Empire�s dominance. After Rome�s decline,  drill largely disappeared and battles became free-for-all combats. Gustav  II Adolf of Sweden led in reintroducing drill techniques in early 17th-  century Europe.</p><p>drill press or drilling machine Machine tool for producing holes in  hard substances. The drill is held in a rotating spindle and is fed into the  workpiece, which is usually clamped in a vise supported on a table. The  drill may be gripped in a chuck with three jaws that move radially in uni�  son, or it may have a tapered shank that fits into a tapered hole in the  spindle. Means are provided for varying the spindle speed and (on some  machines) for automatically feeding the drill into the workpiece.

Originating with the confluence of the Tara and Piva rivers, it follows a  northerly course 285 mi (459 km) to enter the Sava River. Its upper course  is through canyons, while its lower course is wider. The Drina constitutes  a large part of the boundary that separates Bosnia and Herzegovina from  Serbia and Montenegro.</p><p>drive In psychology, an urgent need pressing for satisfaction, usually  rooted in some physiological deficiency or imbalance (e.g., hunger and</p><p>thirst) and impelling the organism to action. Psychologists distinguish  between drives that are innate and directly related to basic physiological  needs (e.g., food, air, and water) and drives that are learned (e.g., drug  addiction). Among the other drives psychologists have identified are  achievement, affection, affiliation, exploration, manipulation, maternity,  pain avoidance, sex, and sleep.</p><p>driver Computer program that acts as an intermediary between the oper�  ating system and a device such as a disk drive, video card, printer, or  keyboard. The driver must contain a detailed knowledge of the device,  including its set of specialized commands. The presence of a separate  driver program frees the operating system from having to understand the  details of every device; instead, the operating system issues general com�  mands to the driver, which in turn translates them into specific instruc�  tions for the device, or vice versa.</p><p>drop forging Process of shaping metal and increasing its strength. In  most forging, an upper die is forced against a heated workpiece positioned  on a stationary lower die. If the upper die or hammer is dropped, the pro�  cess is known as drop forging. To increase the force of the blow, power  is sometimes applied to augment gravity.</p><p>drop spindle See spindle and whorl</p><p>drosophila \dro-'sa-f3-l9\ Any member of about 1,000 species in the  dipteran genus Drosophila, commonly known as fruit flies but also called  vinegar flies. Some species, particularly D. melanogaster, are used exten�  sively in laboratories for experiments on genetics and evolution because  they are easy to raise and have a short life cycle (less than two weeks at  room temperature). More data have been collected concerning the genet�  ics of Drosophila than for any other animal. In the wild, its larvae live in  rotting or damaged fruits or in fungi or fleshy flowers.</p><p>Droste-Hulshoff Vdro-sto-'hiEls-hofV Annette, Baroness von  orig.

May 25, 1848, Meers-  burg, Baden) German writer. One of the great women poets of Germany,  she wrote religious verse, particularly Das geistliche Jahr (1851; �The  Spiritual Year�), but she is best known for detailed, evocative poems about  her native Westphalia. Her stories are considered forerunners of the 19th-  century realistic short story. Her only complete prose work. The Jew�s  Beech (1842), is a psychological study of a villager who murders a Jew.</p><p>Drottningholm Palace \'drut-niq- 1 h6lm\ Royal palace, near Stock�  holm, Sweden. It was designed by Nicodemus Tessin (1615-1681) and  built 1662-86. It shows French Baroque influences in its plan, gardens,  and interior, but it also has Italian Classical elements and is capped by a  Nordic sateri roof. A theater attached to it was built in the 1760s and is  preserved with its original sets and stage machinery as a theatrical  museum. The palace was formerly the Swedish royal family�s summer  residence.</p><p>drought Lack or insufficiency of rain for an extended period that  severely disturbs the hydrologic cycle in an area. Droughts involve water  shortages, crop damage, streamflow reduction, and depletion of ground-  water and soil moisture. They occur when evaporation and transpiration  exceed precipitation for a considerable period. Drought is the most seri�  ous hazard to agriculture in nearly every part of the world. Efforts have  been made to control it by seeding clouds to induce rainfall, but these  experiments have had only limited success.</p><p>drug Any chemical agent that affects the function of living things. Some,  including antibiotics, stimulants, tranquilizers, antidepressants, analgesics,  narcotics, and hormones, have generalized effects. Others, including laxa�  tives, heart stimulants, anticoagulants, diuretics, and antihistamines, act on  specific systems. Vaccines are sometimes considered drugs. Drugs may  protect against attacking organisms (by killing them, stopping them from  reproducing, or blocking their effects on the host), substitute for a miss�  ing or defective substance in the body, or interrupt an abnormal process.  A drug must bind with receptors in or on cells and cannot work if the  receptors are absent or its configuration does not fit theirs. Drugs may be  given by mouth, by injection, by inhalation, rectally, or through the skin.  The oldest existing catalogue of drugs is a stone tablet from ancient Baby�  lonia (c. 1700 bc); the modern drug era began when antibiotics were dis�  covered in 1928. Synthetic versions of natural drugs led to design of drugs  based on chemical structure. Drugs must be not only effective but safe;  side effects can range from minor to dangerous (see drug poisoning). Many</p><p>Drill (Mandrillus leucophaeus).</p><p>J.

See also drug resistance; pharmacology; pharmacy.</p><p>drug addiction or chemical dependency Physical and/or psy�  chological dependency on a psychoactive (mind-altering) substance (e.g.,  alcohol, narcotics, nicotine), defined as continued use despite knowing that  the substance causes harm. Physical dependency results when the body  builds up a tolerance to a drug, needing increasing doses to achieve the  desired effects and to prevent withdrawal symptoms. Psychological  dependency may have more to do with one�s psychological makeup; some  people may have a genetic tendency to addiction. The most common  addictions are to alcohol (see alcoholism), barbiturates, tranquilizers, and  amphetamines, as well as to the stimulants nicotine and caffeine. Initial  treatment (detoxification) should be conducted with medical supervision.  Individual and group psychotherapy are critical elements. Alcoholics  Anonymous and similar support groups can increase the success rate of  other efforts. The ability to admit addiction and the will to change are  necessary first steps.</p><p>drug poisoning or medicinal poisoning Harmful effects of  drugs, from overdose or sensitivity to regular doses. Many medicines are  dangerous; the margin between dose and overdose is often narrow. A nor�  mally safe dose may be toxic in some people, over time, or in combina�  tion with certain foods, alcohol, or other drugs. Safeguards to prevent drug  poisoning include testing in animals, then human volunteers, and then  patients. Drugs unsafe for self-medication are available only to doctors or  by prescription. Pharmacists advise the public on proper use.</p><p>drug resistance Property of a disease-causing organism that allows it  to withstand drug therapy. In any population of infectious agents, some  have a mutation that helps them resist the action of a drug. The drug then  kills more of the nonresistant microbes, leaving the mutants without com�  petition to multiply into a resistant strain. This situation is more likely if  the drug is not taken properly (e.g., a course of antibiotics not completed,  anti-HIV drug doses missed) or not prescribed properly (e.g., an antibi�  otic given for a viral disease). Resistance factors can also be transferred  between species that infect the same body. The overprescription of anti�  biotics in humans and the addition of antibiotics to animal feed have  accelerated the evolution of resistant strains of bacteria, making it increas�  ingly difficult to fight off certain disease-causing organisms.</p><p>Druid Member of a learned class of priests, teachers, and judges among  the ancient Celtic peoples. The Druids instructed young men, oversaw  sacrifices, judged quarrels, and decreed penalties; they were exempt from  warfare and paid no tribute. They studied ancient verse, natural philoso�  phy, astronomy and religious lore; their principal doctrine was belief in  the immortality of the soul and the transmigration of souls. They some�  times practiced human sacrifice to cure gravely ill people or protect war�  riors in battle. The Druids were suppressed in Gaul by the Romans in the  1st century ad and in Britain a little later. They lost their priestly func�  tions in Ireland after the coming of Christianity but survived as poets,  historians, and judges. See also Celtic religion.</p><p>drum or croaker In biology, any of about 160 species (family Sci-  aenidae) of carnivorous, generally bottom-dwelling fishes. Most are  marine, found along warm and tropical seashores. Most can �vocalize�  by moving strong muscles attached to the air bladder, which acts as a  resonating chamber, amplifying the sounds. Drums have two dorsal fins  and are usually silvery. The weakfishes, sea trouts, and squeteagues (genus  Cynoscion ) have a large mouth, jutting jaws, and canine teeth, but most  drums have an underslung lower jaw and small teeth. The largest species,  the totuava, weighs up to 225 lbs (100 kg), but other species are much  smaller. Many drums are food or game fishes. See also bass, kingfish.</p><p>drum Musical instrument, the sound of which is produced by the vibra�  tion of a stretched membrane. Drums are usually either cylindrical or  bowl-shaped. The drum is a universal instrument and very ancient; a drum  dating to 6000 bc has been found in Moravia. Drums have been impor�  tant ritually in cultures worldwide. They may have a definite pitch or be  unpitched; those of Africa, South and Southeast Asia (see tabla), and the  Middle East are mostly pitched, whereas Western drums are more often  unpitched. Drumming has attained its highest degree of development in  Africa and India. From the 13th century, the folk dance in Europe was  accompanied by a single musician playing simultaneously the pipe or fife  and the tabor, a small double-headed snare drum played with one stick.  The side drum, or snare drum, has coiled wires or gut strings strung across  the lower head, which vibrate against it when the upper head is struck.</p><p>The powerful bass drum is used  especially in marching bands. The  pitched timpani are the standard  orchestral drums. Until the 17th cen�  tury, drum parts in Western music  were entirely improvised. The drum  set used in popular music is played  by a single person and normally  includes a snare drum, tom-toms, a  pedal-operated bass drum, and sus�  pended and hi-hat cymbals.</p></section><section><p>drupe Fruit in which the outer  layer is a thin skin, the middle layer  is thick and usually fleshy (though  sometimes tough, as in the almond,  or fibrous, as in the coconut), and the  inner layer (the pit) is hard and stony.</p><p>Within the pit is usually one seed.

It was  built in London by Thomas Killi-  grew for his acting company as the  Theatre Royal (1663). It burned in  1672 and was rebuilt in 1674 with  Christopher Wren as architect. It prospered under such actor-managers as  Colley Cibber and later under David Garrick and Richard Brinsley Sheridan.  An expanded �fireproof� theatre opened in 1794 and burned in 1809.  Rebuilt in 1812 with over 2,000 seats, it declined in popularity from the  1840s, but it revived in the 1880s with melodramas and spectacles and  was the scene of the acting triumphs of Henry Irving and Ellen Terry. More  recently it has played host to many U.S. musicals.</p><p>Drusus Germanicus Vdru-sos-jor-'ma-ni-kosX, Nero Claudius (b.</p><p>38 bc �d. 9) Younger brother of Tiberius and commander of Roman forces  in German territory. The reputed son of Octavian (later Augustus), he was  allowed to take office five years earlier than the legal age. In 13 bc he  became governor of the three Gauls, where he conducted a census and  erected an altar to Augustus. In 12 he marched into Germany, reaching  the Elbe three years later. During those years he was made praetor in 11  and consul in 9. At the Elbe he was thrown from his horse and died. His  son Claudius later became emperor.</p><p>Druze \'driiz\ or Druse Relatively small Middle Eastern religious sect.  It originated in Egypt in 1017 and is named for one of its founders,  Muhammad al-Daraz! (d. 1019/20). Strictly monotheistic and based in  Islam, particularly IsmaTlI Islam, Druze beliefs include an eclectic mix�  ture of elements from Gnosticism, Neoplatonism, Judaism, and Iranian reli�  gion. The Druze believe in the divinity of al-Hakim bi-Amr Allah (985-  1021?), sixth caliph of the Fajimid dynasty of Egypt, and expect him to  return someday to inaugurate a golden age. The Druze are divided hier-  achically into two orders�the sages, who are fully initiated in the beliefs  of the religion, and the ignorant, who constitute the uninitiated lay major�  ity. They permit no converts, either to or from their religion, and no inter�  marriage. Their religious system is kept secret from the outside world,  and they are permitted to deny their faith if their life is in danger. In the  early 21st century they numbered about one million, mostly in Syria and  Lebanon.</p><p>dry cleaning System of cleaning textiles with chemical solvents  instead of water.

Aug. 9, 1631, Aldwinkle, Northamptonshire,  Eng.�d. May 1, 1700, London) British poet, dramatist, and literary critic.  The son of a country gentleman, Dryden was educated at the University  of Cambridge. His poetry celebrating the Restoration so pleased Charles  II that he was named poet laureate (1668) and, two years later, royal his�  toriographer. Even after losing the laureateship and his court patronage  in 1688 with the accession of William III, he succeeded in dominating the  literary scene with his numerous works, many attuned to politics and pub�  lic life. Several of his nearly 30 comedies, tragedies, and dramatic  operas�including Marriage A-la-Mode (1672), Aureng-Zebe (1675), and  All for Love (1677)�were outstandingly successful. His Of Dramatick  Poesie (1668) was the first substantial piece of modern dramatic criticism.  Turning away from drama, he became England�s greatest verse satirist,  producing the masterpieces Absalom and Achitophel (1681) and Mac  Flecknoe (1682). He also produced extensive translations of Latin poetry,  including Virgil�s Aeneid.</p><p>dryopithecine X.drl-o-'pi-tho-.smX Any member of the genus Dryo-  pithecus, a group of extinct apelike animals. The species are representa�  tive of a group of generalized apes that includes the ancestors of both the  modern apes and humans. Fragmentary materials found over a widespread  area, including Europe, Africa, and Asia, have been attributed to other  groups but were probably remains of Dryopithecus. Dryopithecines are  found as fossils in Miocene and Pliocene deposits (23.8-1.8 million years  old) and apparently originated in Africa. Several distinct forms are known,  including small, medium, and large (GORiLLA-sized). Dryopithecines lacked  most of the specializations that distinguish modern apes from humans.</p><p>DSL in full Digital Subscriber Line Broadband digital communica�  tions connection that operates over standard copper telephone wires. It  requires a DSL modem, which splits transmissions into two frequency  bands: the lower frequencies for voice (ordinary telephone calls) and the  upper band for digital data, especially for connection to the Internet. Data  can be transferred via DSL at much higher rates than with ordinary dial-up  modem service; the range of DSL signals, however, is very small. Con�  nections can be made only within a few miles of the nearest transmitting  station. DSL and �xDSL� are umbrella terms under which a variety of  protocols and technologies fall. ADSL (Asymmetric DSL) is a popular  type of DSL in which most of the bandwidth of the connection is devoted  to downloading data from the network to the user, leaving only a small-  scale connection for uploading data. In HDSL (High bit-rate DSL) and  SDSL (Symmetric DSL) the data stream is symmetric; that is, the  upstream and downstream rates are the same. UDSL (Unidirectional  DSL), VDSL (Very high data rate DSL), and others still under develop�  ment are intended to offer even greater rates of data transmission.</p><p>Du Bois \dii-'b6is\, W(illiam) E(dward) B(urghardt) (b. Feb. 23,  1868, Great Barrington, Mass., U.S.�d. Aug. 27, 1963, Accra, Ghana)  U.S. sociologist and civil-rights leader. He received a Ph.D. from Harvard  University in 1895. Two years later he accepted a professorship at Atlanta  University, where he conducted empirical studies on the social situation  of African Americans (1897-1910). He concluded that change could be  attained only through agitation and protest, a view that clashed with that  of Booker T. Washington. His famous book The Souls of Black Folk</p><p>appeared in 1903. In 1905 Du Bois founded the Niagara Movement, the  forerunner of the NAACP. In 1910 he left teaching to become the  NAACP�s director of research and editor of its magazine, Crisis (1910�  34). He returned to Atlanta University in 1934 and devoted the next 10  years to teaching and scholarship. After a second research position with  the NAACP (1944-48), he moved steadily leftward politically. In 1951  he was indicted as an unregistered agent of a foreign power (the Soviet  Union); though a federal judge directed his acquittal, he was by then  completely disillusioned with the U.S. In 1961 he joined the Communist  Party, moved to Ghana, and renounced his U.S. citizenship.</p><p>Du Buat Vdie-biE-'aV, Pierre-Louis-Georges (b. April 23,1734, Tor-  tisambert, France�d. Oct. 17, 1809, Vieux-Conde) French hydraulic  engineer. He compiled experimental data from which he determined his  basic algebraic expression for discharge from pipes and open channels.  Though valid only within the range of his experimental data, this equa�  tion provided the best means at the time of predicting the performance of  water-supply systems and similar works. His emphasis on achieving  results that would be of practical use strongly influenced the development  of experimental hydraulics in the 18th�19th centuries.</p><p>du Cange, Charles du Fresne, seigneur See Charles du Fresne,  seigneur du Cange</p><p>Du Fu Vdti-'fiA or Tu Fu (b. 712, Xiangyang, China�d. 770, Hunan)  Chinese poet, often considered the greatest of all time. After a traditional  Confucian education, he failed the important civil service examinations  and consequently spent much of his life wandering, repeatedly attempt�  ing to gain court positions, with mixed success. His early poetry, which  celebrates the natural world and bemoans the passage of time, garnered  him renown. He suffered periods of extreme personal hardship, and as he  matured his verse began to express profound compassion for humanity.  An expert in all the poetic genres of his day, he is renowned for his superb  classicism and skill in prosody, though many of the subtleties of his art  do not survive translation.</p><p>du Maurier \du-'m6r-e-,a.

Oct. 6, 1896, London, Eng.) British caricaturist  and novelist. Forced to abandon painting for drawing when he was blinded  in one eye, his skilled draftsmanship and engaging personality quickly  established his success. His drawings for Punch, Once a Week, and The  Leisure Hour were acute commentaries on the Victorian scene. His highly  successful novel Trilby (1894), about an artist�s model who falls under  the spell of the musician Svengali, has entered popular mythology. His  other novels were Peter Ibbetson (1891) and The Martian (1897). His  granddaughter Daphne du Maurier was also a writer.</p><p>Du Mont, Allen B(alcom) (b.

He became inter�  ested in television in 1928, as chief engineer at the De Forest Radio Co.,  and concluded that television required a purely electronic system to work.  In 1931 he set up what would become Allen B. Du Mont Laboratories,  where he improved the cathode-ray tube and developed the modem oscil�  loscope. In 1937 he began manufacturing the first commercial television  receivers. After World War II he marketed the first widely available TV  receivers and set up one of the first TV broadcasting networks. He served  with the National Television System Committee formulating broadcast�  ing standards and worked with the Federal Communications Commission  in allocating frequencies for TV channels.</p><p>Dual Alliance See Austro-German Alliance, Franco-Russian Alliance  dual-aspect theory See double-aspect theory  Dual Monarchy See Austria-Hungary</p><p>dualism In philosophy, any pair of irreducible, mutually heterogeneous  principles used to analyze the nature and origins of knowledge (episte�  mological dualism) or to explain all of reality or some broad aspect of it</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>576 I Dubayy &#x25BA; Duchamp</p><p>(metaphysical dualism); also, any theory that employs dualisms.

It is surrounded by the emirates  of Abu Dhabi and Al-Shariqah (Sharjah), and it has 45 mi (72 km) of  coastline on the Persian Gulf. Occupying an area of 1,510 sq mi (3,900  sq km), it is the second most populous and second largest state of the  federation. Most of its population live in or near its capital, Dubai city  (pop., 1995: 669,181). Settled in 1799 by people from Abu Dhabi, Dubayy  became a locally powerful state in the early 19th century, and until the  1930s it was known for its pearl exports. It has since been enriched by  petroleum exports. Dubai city is now a centre for most of the banks and  insurance companies of the UAE.</p><p>Dubcek Vdiib-.chekV Alexander (b. Nov. 27, 1921, Uhrovec,  Czech.�d. Nov. 7, 1992, Prague) Czech politician. In World War II he  took part in the underground resistance to Nazi occupation. After the war  he rose in Communist Party ranks to become a member of the Presidium  of the party�s Central Committee (1962). In 1968 he forced Antonin  Novotny (1904-75) to resign and replaced him as head of the Commu�  nist Party. He introduced liberal reforms in the brief period known as the  Prague Spring, which ended when the Soviet Union invaded Czechoslo�  vakia in August 1968. Demoted to lesser posts, he was expelled from the  party in 1970. He returned to prominence in 1989 after the Communist  Party had given up its monopoly on power, and was elected speaker of  the Czech parliament.</p><p>Dubinsky, David (b.

The  son of a baker in Russian Poland, he was sent to Siberia in 1908 for his  union activities. In 1911 he escaped and immigrated to the U.S., where  he renewed his union work. In 1932 he became president of the Interna�  tional Ladies' Garment Workers' Union (ILGWU), a post he held until  1966. As president, he transformed the ILGWU from a small, fractious  regional organization into a model international union. He also played a  significant role in the merger of the American Federation of Labor and  the Congress of Industrial Organizations (see AFL-CIO) in 1955.</p><p>Dublin ancient Eblana City and county borough (pop., 2002 prelim.:  city, 495,101; county borough, 1,122,600), capital of Ireland. On the River  Liffey, it was settled by Danish Vikings arriving in the area in the 9th cen�  tury ad; they held it until it was taken by the Irish in the 11th century.  Under English control in the 12th century, it was given a charter by Henry  II, establishing it as a seat of government. It prospered in the 18th cen�  tury as a centre of the cloth trade, and its harbour dates from this period.  In the 19th and 20th centuries it was the site of bloody nationalist vio�  lence, including the 1867 Fenian movement and the 1916 Easter Rising. It  is the country�s chief port, centre of finance and commerce, and seat of  culture. Its Guinness Brewery is the country�s largest private employer.  Educational and cultural institutions include the University of Dublin; the  National Library and National Museum are housed on the grounds of  Leinster House (1748), now the seat of the Irish parliament.</p><p>Dublin, University of or Trinity College Oldest university in Ire�  land, founded in 1592 by Elizabeth I and endowed by the city of Dublin.  Trinity was originally intended to be the first of many constituent colleges  of the university, but no others were established, and the two names  became interchangeable. The full benefits of the university (degrees, fel�  lowships, scholarships, etc.) were for many years limited to Anglicans,  but in 1873 all religious requirements were eliminated. The university has  faculties of arts (humanities and letters), sciences, business, economic and  social studies, engineering and systems sciences, health sciences, and  graduate studies. The library contains many illuminated manuscripts,  including the Book of Kells.</p><p>Dublin Bay prawn See scampi</p><p>Dubnow Vdub-.noA, Simon Markovich (b. Sept. 10, 1860,  Mstislavl, Russia�d. December 1941, Riga, Latvia, U.S.S.R.) Russian  Jewish historian. Largely self-educated, he gained notice as a scholar of  Jewish history before the Bolshevik Revolution prompted him to leave his  native Russia for Germany in 1922. He emphasized the cultural autonomy  of the Jewish people throughout history, rejecting assimilation but also</p><p>opposing Zionism as unrealistic. His best-known works were History of  the Jews (10 vol., 1925-30) and History of Hasidism (1931). He fled Nazi  Germany in 1933 for Riga, Latvia, where he was eventually killed by the  Germans.</p><p>Dubos \du-'boz\, Rene (Jules) (b. Feb. 20, 1901, Saint-Brice,  France�d.

His pioneering research in iso�  lating antibacterial substances from soil microorganisms led to the dis�  covery of major antibiotics. He researched and wrote on antibiotics,  acquired immunity, tuberculosis, and the bacteria of the gastrointestinal  tract. In his later years his interest shifted to the relationship of humans  to the natural environment; his So Human an Animal (1968) won the  Pulitzer Prize.

Founded in  the 7th century by Roman refugees, it came under Byzantine rule after  the fall of Rome. It acknowledged Venetian suzerainty (1205-1358) but  remained largely independent and became a mercantile power. It was  known as a centre of Slavic literature and art in the 15th�17th centuries.  Subjugated by Napoleon I in 1808, it was passed to Austria in 1815 and  to Yugoslavia in 1918. It was bombed by the Serbs (1991-92) during  Croatia�s struggle for independence. The old city, enclosed by medieval  city walls, contains 14th-century convents and the 15th-century Rector�s  Palace.</p><p>Dubuffet VdlE-btE-'feX, Jean (-Philippe-Arthur) (b. July 31, 1901,  Le Havre, Fr.�d. May 12, 1985, Paris) French painter, sculptor, and  printmaker. He studied painting in Paris, but in 1929 he began making a  living as a wine merchant. When he returned to art full-time in the early  1940s, he became a leading artist in Paris and proponent of art brut. He  executed crude images incised into rough impasto surfaces made of mate�  rials such as sand, plaster, tar, gravel, and ashes bound with varnish and  glue, and sculptural works made of junk materials; their unfinished  appearance provoked public outrage. In the 1960s he experimented with  musical composition and architectural environments, and in his later years  he produced large fibreglass sculptures for public spaces.</p><p>Duby, Georges (b. Oct. 7, 1919, Paris, France�d. Dec. 3, 1996, near  Aix-en-Provence) Prolific and influential French historian. After receiv�  ing a doctorate in history at the Sorbonne (University of Paris) in 1950,  Duby taught at the university of Marseilles-Aix-en-Provence. In 1970 he  moved to the College de France, where he served as professor of the his�  tory of medieval societies until 1993. The most influential of his many  works was his dissertation, La Societe awe Xle et Xlle siecles dans la  region maconnaise (�Society in the Maconnais in the 11th and 12th Cen�  turies�), published in 1953, which helped shape a new understanding of  medieval society. He also served as director of the Societe d�Edition de  Programmes de Television, a public television production agency. He was  elected to the Academie Fran�aise in 1987.</p><p>Duccio \'dut-cho\ (di Buoninsegna) (b. 13th century, Siena, Repub�  lic of Siena�d. c. 1318, Siena?) Italian painter. Little is known of his  life, but several commission records survive, as well as two documented  works, the Rucellai Madonna for the Florentine church of Santa Maria  Novella (1285) and the famous Maesta altarpiece for Siena Cathedral  (1308-11); both represent landmarks in the history of Italian painting. His  style reflected the influence of Cimabue and Byzantine art, though he intro�  duced a warmth of human feeling that was comparable to that of Giotto  in Florentine painting. He was the leading painter in Siena, one of Italy�s  most vital artistic centres in the Middle Ages.</p><p>Duchamp Ndui-'shaA, Marcel (b. July 28, 1887, Blainville, France�d.  Oct. 2, 1968, Neuilly) French artist and art innovator. In 1913 he caused  a sensation at the Armory Show with his painting Nude Descending a  Staircase, No. 2 (1912), which combined the principles of Cubism and  Futurism. His irreverence for conventional aesthetic standards then led him  to devise his famous ready-mades: in 1913 he exhibited Bicycle Wheel,  which was simply an ordinary bicycle wheel displayed as a work of art,  and in 1917 he exhibited a urinal he entitled Fountain. Intended as a deri�  sive gesture against the excessive importance attached to works of art, the  ready-mades ushered in an era when contemporary art became in itself a  mixture of creation and criticism. In Paris in 1919 he established contact  with the Dada group of artists, whose nihilistic ideas he had anticipated.  During this period he exhibited a photograph of the Mona Lisa with a</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>duck &#x25BA; Duisburg i 577</p><p>moustache and goatee added, a gesture that expressed the Dadaists� scorn  for the art of the past. He greatly influenced the Surrealists, and his atti�  tude toward art and society led to Pop art and other modern and post�  modern movements. A legend in his lifetime, he is considered one of the  leading spirits of 20th-century art.</p><p>duck Any of various relatively small, short-necked, large-billed water-  fowl (several genera in subfamily Anatinae, family Anatidae). The legs  of true ducks (Anatinae) are placed rearward (as are those of swans),  resulting in a waddling gait. Most true ducks differ from swans and true  geese (see goose) in that male ducks molt twice annually, females lay  large clutches of smooth-shelled eggs, and both sexes have overlapping  scales on the skin of the leg and exhibit some differences between sexes  in plumage and in call. All true ducks except shelducks and sea ducks (see  diving duck) mature in the first year and pair only for the season. They are  generally divided into three groups: perching ducks, dabbling ducks, and  diving ducks. The whistling duck species, also called tree ducks, are not  true ducks but are more closely related to geese and swans.</p><p>duck hawk See peregrine falcon  duckbill See platypus</p><p>ductility Capacity of a material to deform permanently (e.g., stretch,  bend, or spread) in response to stress. Most common steels, for example,  are quite ductile and hence can accommodate local stress concentrations.  Brittle materials, such as glass, cannot accommodate concentrations of  stress because they lack ductility, and therefore fracture easily. When a  material specimen is stressed, it deforms elastically (see elasticity) at first;  above a certain deformation, called the elastic limit, deformation becomes  permanent.</p><p>ductus arteriosus Vdok-tos-ar-.tir-e-'o-sosN Channel between the pul�  monary artery and the aorta in the fetus, which bypasses the lungs to dis�  tribute oxygen received through the placenta from the mother�s blood. It  normally closes once the baby is born and the lungs inflate, separating the  pulmonary and systemic circulations. Closure before birth causes circu�  latory problems. If the ductus stays open after birth (patent ductus arte�  riosus, more common in premature births), oxygenated and deoxygenated  blood mix. Alone, this may not be serious; in some heart malformations  it is even necessary for life.</p><p>Dudley City (pop., 1998 est.: 311,500), West Midlands, England. It is  the site of several Saxon and Norman fortifications. Coal and ironstone  have been mined there since the Middle Ages. By the mid-19th century  there were numerous blast furnaces, and the resultant pollution helped to  give the area to the north and east the name �Black Country.� Metalwork�  ing is an important industry.</p><p>Dudley, Dud (b. 1599, England?�d. 1684, England?) English iron�  master. He was an illegitimate son of Edward Sutton, the 9th Baron of  Dudley, who recalled him from Oxford in 1619 to manage the family�s  ironworks in Staffordshire. He was the first to experiment with smelting  iron ore in a coAL-fired furnace. Previously, charcoal had been exclusively  used for smelting iron, but it was becoming increasingly costly, and  unpopular, with the depletion of England�s forests for fuel. Dudley pat�  ented his innovation in 1621, but the poor quality of his metal limited its  sale.

Due process standards are sometimes  referred to as either substantive or procedural. Substantive due process  refers to a requirement that laws and regulations be related to a legitimate  government interest (e.g., crime prevention) and not contain provisions  that result in the unfair or arbitrary treatment of an individual. The 5th  Amendment to the Constitution of the United States states that �no person  shall...be deprived of life, liberty, or property, without due process of  law.� This right was extended to the states by the 14th Amendment (1868).  Fundamental to procedural due process are adequate notice before the  government can deprive one of life, liberty, or property, and the oppor�  tunity to be heard and defend one�s rights. The boundaries of due process  are not fixed and are the subject of endless judicial interpretation and  decision making. See also rights of the accused; double jeopardy.</p><p>duel Formal combat with weapons fought between two persons in the  presence of witnesses. Intended to settle a quarrel or point of honour, it</p><p>represented an alternative to the usual process of justice. The judicial duel,  or trial by battle, is reported in ancient sources and was prevalent in  medieval Europe. A judge could order two parties to meet in a duel to  settle a matter. It was believed that through such an appeal to the �judg�  ment of God� the righteous would emerge victorious; the loser, if still  alive, was dealt with according to the law. Duels of honour were private  encounters over real or imagined slights or insults. Eventually fought with  pistols, duels were frequent in France and Germany in the 19th and early  20th centuries, and they were legal or encouraged by the fascist regimes  in Italy and Germany. By the late 20th century they were prohibited; the  last duel recorded in France occurred in 1967. The most famous duel in  the U.S. was that between Alexander Hamilton and Aaron Burr (1804).

Ordained a priest, he acquired a high reputation for  learnedness. In 1428 he joined the papal singers in Rome, by which time  his works had made him famous. He returned to Cambrai c. 1440, where  he would supervise the cathedral�s music for the rest of his life, apart from  a period (1451-58) working for the duke of Savoy. Many musicians came  to learn under him, and he enjoyed renown as the greatest living com�  poser. His surviving works, which employ a richly harmonic texture,  include some 90 chansons, 13 motets, and at least 6 complete masses,  including such early cantus-firmus works as L�Homme arme and Se la  face ay pale.</p><p>Dufy \dtE-'fe\, Raoul (b.

In 1900 he studied at the  Ecole des Beaux-Arts in Paris and experimented with Impressionism, but  by 1904 he had adopted the flat areas of bright colour typical of Fauvism.  In the early 1920s he developed a distinctive style characterized by rapid  calligraphic drawing on backgrounds of bright, decorative colour; his  subjects were usually recreational scenes such as horse races, parades, and  concerts. He also designed textiles and made numerous book illustrations.</p><p>dugong Vdii-.gaqV Large marine mammal ( Dugong dugon, the sole liv�  ing member of the family Dugongidae) that lives in shallow coastal waters  from the Red Sea and eastern Africa to the Philippines, New Guinea, and  northern Australia. It is 7-11 ft (2.2-3.4 m) long and usually weighs 500-  800 lbs (230-360 kg). Its round, tapered body ends in a flipper with paired,  pointed, horizontal branches. The forelimbs are rounded flippers; there  are no hind limbs. The head blends into the body, and the snout is broad,  square, and bristled. Dugongs live in pairs or in groups of up to six indi�  viduals. Once heavily hunted for their meat, hides, and oil, they are now  protected throughout most of their range, though some populations remain  in danger of extermination.

It lies at the  junction of the Rhine and Ruhr rivers and is connected with the North Sea  ports by the Rhine-Herne Canal. Known to the Romans as Castrum Deu-  tonis, it was mentioned in ad 740 as Diuspargum, a seat of the Frankish  kings. It passed to Cleves in 1290 and, with Cleves, to Brandenburg in  1614. After suffering heavily in the Thirty Years' War, it revived as the  seat of a Protestant university from 1655 to 1818. With increasing indus�  trialization after 1880, it is now one of the world�s largest inland ports.</p><p>Zebra duiker (Cephalophus zebra).</p><p>KENNETH W.

His studies of microscopic ani�  mal life frequently found in decaying organic materials led him in 1834  to propose a new group of one-celled animals that he called Rhizopoda.  He named the seemingly formless life substance that oozed outward  through openings in certain shells sarcode', later it became known as pro�  toplasm. This work led him in 1835 to argue against Christian Gottfried  Ehrenberg�s theory that microscopic organisms have the same organs as  higher animals.

The wife  of a duke is a duchess. The Romans gave the title dux to high military  commanders with territorial responsibilities. It was adopted by the bar�  barian invaders of the Roman Empire and was used in their kingdoms and  also in France and Germany for rulers of very large areas. In some Euro�  pean countries a duke is a sovereign prince who rules an independent  duchy.

From there he visited the U.S., where  George Gershwin suggested his new name and advised him not to be afraid  of �going low-brow.� He composed classical works in Europe, including  Zephyr et Flore (1925) for the Ballets Russes but returned to the U.S. in  1929. With lyricists including Edgar Harburg and Howard Dietz, he wrote  music for shows (including Walk a Little Faster , 1932) and movies  (including Cabin in the Sky, 1943, and Sadie Thompson, 1944). His songs  include �April in Paris,� �Taking a Chance on Love,� and �Banjo Eyes.�</p><p>Duke University Private university in Durham, N.C. It was created in  1924 through an endowment from James B. Duke, although the original  college (Trinity) traces its roots to the mid 19th century. Duke maintained  separate campuses for undergraduate men and women until the 1970s.  Besides an undergraduate liberal arts college, the university includes  schools of business, divinity, engineering, environmental studies, gradu�  ate studies, law, medicine (including a medical centre), and nursing.</p><p>Dukhobor See Doukhobor</p><p>Dulany \d3-'la-ne\, Daniel (b. June 28, 1722, Annapolis, Md.�d.  March 17, 1797, Baltimore, Md., U.S.) American lawyer. He was edu�  cated in England and became a lawyer after returning to Maryland. After  serving in Maryland�s legislative assembly (1751-54), he was appointed  to the Governor�s Council (1757-76) in recognition of his support for the  colony�s proprietary government. Though he wrote an influential pam�  phlet criticizing the Stamp Act (1765), he opposed revolt against British  rule and remained a loyalist during the American Revolution.</p><p>Dulbecco \d3l-'be-ko\, Renato (b. Feb. 22, 1914, Catanzaro, Italy)  Italian-born U.S. virologist. He received his M.D. from the University of  Turin in 1936 and immigrated to the U.S. in 1947. With Marguerite Vogt  he pioneered the culturing of animal viruses and investigated how certain  viruses gain control of the cells they infect. They showed that polyoma  virus inserts its DNA into the DNA of the host cell and that the cell is  then transformed into a cancer cell, reproducing the viral DNA along with</p><p>its own and producing more cancer cells. Dulbecco suggested that human  cancers could be caused by similar reproduction of foreign DNA frag�  ments. He shared a 1975 Nobel Prize with two former students, Howard  Temin (b. 1934) and David Baltimore. The last of his academic appoint�  ments in the U.S. and Britain was as president of the Salk Institute.</p><p>dulcimer or hammered dulcimer Stringed musical instrument in  which the strings are beaten with small hammers rather than plucked. Its  soundbox is flat and usually trapezoidal; each pair of strings produces a  single note, and the pairs slope upward alternately left and right to facili�  tate rapid playing. The Hungarian cimbalom is a large dulcimer with legs  and a damper pedal, much used in Roma (Gypsy) orchestras. The Appa�  lachian dulcimer is a narrow zither with a fretted fingerboard and three to  five strings, which are stopped with one hand and plucked with a plec�  trum held in the other.</p><p>DuLhut \dLE-'ltBt\, Daniel Greysolon, Lord (b. c. 1639, Saint-  Germain-Laval, France�d. Feb. 25/26, 1710, Montreal) French soldier  and explorer. He made two voyages to New France before 1674 and  returned to Montreal in 1675. He negotiated fur-trade agreements with  Indian tribes, rescued Louis Hennepin from the Sioux, assisted count de  Frontenac in the campaign against Indian allies of the British, and is cred�  ited with establishing French control over the land north and west of Lake  Superior. Duluth, Minn., is named for him.</p><p>Dulles Vdo-losV Allen W(elsh) (b. April 7, 1893, Watertown, N.Y.,  U.S.�d. Jan. 29, 1969, Washington, D.C.) U.S. diplomat and adminis�  trator. He held diplomatic posts before practicing law with his brother,  John Foster Dulles. In World War II he served in the Office of Strategic  Services. After the war he chaired a committee to survey the U.S. intel�  ligence system. When the Central Intelligence Agency was established in  1951, he became its deputy director. As director (1953-61), he oversaw  the agency�s early successes, but the U-2 Affair (1960) and the Bay of Pigs  invasion (1961) led to his resignation.</p><p>Dulles, John Foster (b. Feb. 25, 1888, Washington, D.C., U.S.�d.  May 24, 1959, Washington, D.C.) U.S. secretary of state (1953-59). He  was counsel to the American Peace Commission at Versailles, France, and  later helped oversee the payment of World War I reparations. He helped  prepare the charter of the UN and was a delegate to its General Assem�  bly (1946-49). He negotiated the complex Japanese peace treaty (1949-  51). As secretary of state under Pres. Dwight D. Eisenhower, he advocated  active opposition to Soviet actions and developed the Eisenhower Doc�  trine. His critics considered him inflexible and harsh and a practitioner of  �brinkmanship� for raising international tensions and bringing the coun�  try to the brink of war; later assessments credit his firmness in checking  communist expansion.</p><p>Duluth \do-'luth\ City (pop., 2000: 86,918) and inland port, northeast�  ern Minnesota, U.S. It is situated on Lake Superior at the mouth of the St.  Louis River, opposite Superior, Wis. The combined Duluth-Superior har�  bour is the western terminus of the St. Lawrence Seaway. Through it are  shipped iron ore, coal, grain, and oil. The site was named after Daniel  DuLhut, one of the French voyageurs who visited the area in the 17th cen�  tury. It was laid out in 1856 and incorporated as a city in 1870.</p><p>Duma Russian Gosudarstvennaya Duma ("State Assem�  bly") Elected legislative body that, with the State Council, constituted  the imperial Russian legislature (1906-17). It had only limited power to  control spending and initiate legislation, and the four Dumas that con�  vened (1906, 1907, 1907-12, 1912-17) rarely enjoyed the cooperation of  the ministers or the emperor, who retained the right to rule by decree when  the Duma was not in session. In the Soviet era, soviets were the basic unit  of government. After the fall of the Soviet Union (1991), the Russian par�  liament (composed of the Congress of People�s Deputies and the Supreme  Soviet) exercised legislative responsibilities until 1993, when conflicts  with Pres. Boris Yeltsin reached a crisis. Parliament�s revolt was suppressed  by military force, and a new constitution established a new parliament  composed of a Federation Council (in which all 89 of Russia�s republics  and regions have equal representation) and a Duma, with 450 members,  half elected through proportional representation on a party basis and half  through single-member constituencies. The president may override and  even dissolve the legislature under certain circumstances.</p><p>Dumas \duj-'ma,\ English \d(y)u-'ma, , d(y)u-,ma\ / Alexandre known  as Dumas pere (b.

In the historic county of Dumfriesshire, the town is situated  on the left bank of the River Nith near the border with England. It is the  main market centre for an intensive livestock-farming region. The poet  Robert Burns lived there from 1791 to 1796 and is buried there; his house  is now a museum.</p><p>Dummer, Jeremiah (b. 1681, Boston, Mass.�d. May 19, 1739,  Plaistow, Essex, Eng.) American lawyer and colonial agent. In England  in 1708 he defended Massachusetts� claim to Martha�s Vineyard. As colo�  nial agent in England for Massachusetts (1710-21) and for Connecticut  (1712-30), he was a diligent advocate for the colonies. In 1715 he wrote  a pamphlet defending the charter rights of the New England colonies.</p><p>Dummett, Sir Michael A(nthony) E(ardley) (b. June 27, 1925,  London, Eng.) British philosopher. Dummett has done influential work in  the philosophy of language, metaphysics, logic, and the philosophy of  mathematics; he is also one of the foremost expositors of the work of Gott�  lob Frege. He is known chiefly for his defense of antirealism (see realism)  and his attempt to explicate sentence meaning in terms of �assertibility  conditions� rather than truth conditions. His major works include Frege:  Philosophy of Language (1973), Truth and Other Enigmas (1978), The  Logical Basis of Metaphysics (1991), and The Seas of Language (1993).</p><p>Dumont d'Urville \dffi-mo n -diEr- , vel\, Jules (-Sebastien-Cesar)</p><p>(b.

His exploration of the South Pacific (1826�  29) resulted in extensive revision of charts of South Sea waters and redes�  ignation of island groups into Melanesia, Micronesia, Polynesia, and  Malaysia. In 1830 he conveyed the exiled king Charles X to England. He  set sail for Antarctica in 1837; though unable to penetrate the pack ice,  his expedition surveyed the Straits of Magellan, discovered Joinville  Island and Louis Philippe Land, and sighted the Adelie coast (named for  Dumont�s wife) before returning in 1840.</p><p>Dumuzi-Abzu Vdu-mii-ze-'ab-.ziiV In Mesopotamian religion, a Sumer�  ian fertility goddess.

Rising in the Tatra  Mountains near the Slovakia border, it flows about 156 mi (251 km)  northeast into the Vistula River. It was the scene of heavy fighting during  World War I in the Austro-German offensive. In 1975 Czechoslovakia and  Poland modified their border along the Dunajec to permit Poland to con�  struct a dam for irrigation in the region southeast of Krakow.</p><p>Dunant XdiB-'naA, (Jean-) Henri (b. May 8, 1828, Geneva,  Switz.�d. Oct. 30, 1910, Heiden) Swiss humanitarian. An eyewitness to  the Battle of Solferino, he organized emergency aid services for the Aus�  trian and French wounded. In 1862 he proposed the formation of volun�  tary relief services in all countries and proposed an international  agreement covering the war wounded. In 1864 he founded the Red Cross,  and the Geneva Convention came into being. He continued to promote  interest in the treatment of prisoners of war, the abolition of slavery, inter�  national arbitration, disarmament, and the establishment of a Jewish  homeland. In 1901 he shared with Frederic Passy (1822-1912) the first  Nobel Peace Prize.</p><p>Dunaway, (Dorothy) Faye (b. Jan. 14, 1941, Bascom, Fla., U.S.)  U.S. film actress. She acted in several off-Broadway plays (1962-67)</p><p>before making her film debut in The Happening (1967). She became an  international star in Bonnie and Clyde (1967). In her best roles, such as  those she played in Bonnie and Clyde, Chinatown (1974), and Network  (1976, Academy Award), she gave textured performances that embodied  the spirit of the films. She later starred in notable films such as Mommie  Dearest (1981), Barfly (1987), and Arizona Dreams (1993).</p><p>Dunbar, Paul Laurence (b. June 27, 1872, Dayton, Ohio, U.S.�d.  Feb. 9, 1906, Dayton) U.S. author.</p><p>The son of former slaves, Dunbar  became the first African American  writer to try to live by his writings  and one of the first to attain national  prominence. He wrote for a largely  white readership, using black dialect  and depicting the pre-Civil War  South in pastoral, idyllic tones. His  verse collections include Oak and  Ivy (1893), Majors and Minors  (1895), and Lyrics of Lowly Life  (1896). His poems reached a wide  readership, and he gave readings in  the U.S. and England. He also pub�  lished four short-story collections  and four novels, including The Sport  of the Gods (1902).</p><p>Dunbar, William (b. 1460/65,</p><p>Scotland�d. before 1530) Scottish -</p><p>poet. He was attached to the court of</p><p>James IV. Of the more than 100 poems attributed to him, most are short  occasional pieces, ranging from gross satire to hymns of religious exal�  tation. The longer works include the charming dream allegory �The Gol-  dyn Targe,� the nuptial song �The Thrissill and the Rois,� and �The  Flyting of Dunbar and Kennedie,� a virtuoso piece of personal abuse  directed at a rival. Dunbar was the dominant makar (courtly poet) in the  golden age of Scottish poetry.</p><p>Duncan I (d. Aug. 1, 1040, near Elgin, Moray, Scot.) King of the Scots  (1034-40). The grandson of King Malcolm II, his accession to the throne  violated the system in which kingship alternated between two branches  of the royal family. He was challenged by Macbeth, mormaer (subking)  of Moray, who was the inspiration for the play by William Shakespeare and  who may have had a stronger claim to the throne. Macbeth murdered  Duncan in 1040, and Duncan�s elder son later killed Macbeth and ruled  as Malcolm III Canmore.</p><p>Duncan, David Douglas (b. Jan. 23, 1916, Kansas City, Mo., U.S.)  U.S. photojournalist. After graduating from college, he became a freelance  photographer. In 1946 he joined the staff of Life magazine and covered  the Korean War (1950); his photographs depicting the life of the ordinary  soldier were published in This Is War! (1951). Resuming his freelance  life, in 1956 he met Pablo Picasso, with whom he became fast friends;  Duncan later published several photographic essays on Picasso�s works,  including The Private World of Pablo Picasso (1958) and Picasso�s Pic�  assos (1961).</p><p>Duncan, Isadora orig. Angela Duncan (b. May 26, 1877, or May  27, 1878, San Francisco, Calif., U.S.�d. Sept. 14, 1927, Nice, Fr.) U.S.  interpretive dancer. She rejected the conventions of classical ballet and  based her technique on natural rhythms and movement inspired by ancient  Greece, dancing barefoot in a tunic without tights. Enjoying little success  in the U.S., she moved to Europe in 1898. She toured Europe, giving  recitals to great acclaim throughout her life and earning notoriety for her  liberated unconventionality, and she founded several dance schools. She  was strangled when her long scarf became entangled in the rear wheel of  the car in which she was riding. Her emphasis on �free dance� made her  a precursor of modern dance, and she became an inspiration to many  avant-garde artists.</p><p>Dundee \,d3n-'de\ City and royal borough (pop., 2001: 145,663), east�  ern Scotland. It constitutes the council area of Dundee City in the historic  county of Angus. An important seaport, it is situated on the Firth of Tay,  an inlet of the North Sea. Earliest mention of the town dates from the late  12th century, and over the next four or five centuries it was repeatedly  sacked, with much bloodshed, by the English.

They vary from  0.2 to more than 1 in. (5-30 mm) long. In early summer it buries itself  and the ball and feeds on it. Later in the season the female deposits eggs  in dung balls, on which the larvae will later feed. They are usually round  with short wing covers (elytra) that expose the end of the abdomen. They  can eat more than their own weight in 24 hours and are considered help�  ful because they hasten the conversion of manure to substances usable by  other organisms.</p><p>Dungannon Won-'ga-nonV District (pop., 2001: 47,735), Northern Ire�  land. Created in 1973, it extends from Lough Neagh to the district of Fer�  managh and from the foothills of the Sperrin Mountains to the River  Blackwater and the republic of Ireland. An essentially pastoral area, its  early history is linked with the O�Neills, earls of Tyrone, whose chief resi�  dence was at the town of Dungannon, the district seat. The Irish Parlia�  ment�s independence was first proclaimed there in 1782.</p><p>Dungeness crab Vdon-jo-nosN Edible crab ( Cancer magister ) found  along the Pacific coast from Alaska to lower California, one of the coast�s  largest and most important commercial crabs. The male is 7-9 in. (18-23  cm) wide and 4-5 in. (10-13 cm) long. The reddish brown upper surface  is lighter toward the back; the legs and undersurface are yellowish. It lives  on sandy bottoms below the high-tide mark. Closely related North Ameri�  can species are the rock crab of the Atlantic coast, the Jonah crab in coastal  waters from New England to Canada, and the red and Pacific rock crabs,  both in Pacific coastal waters. All are edible, but their commercial impor�  tance varies.</p><p>Dunham, Katherine (b. June 22, 1910, Joliet, Ill., U.S.) U.S. dancer,  choreographer, and anthropologist  noted for her interpretation of tribal  and ethnic dances. In 1931 she  opened a dance school in her native  Chicago. In 1940 she formed the  U.S.�s first all-black dance company,  for which she choreographed revues  based on her anthropological  research in the Caribbean; her early  works included Tropics and Le Jazz  hot. She later received a Ph.D. in  anthropology from the University of  Chicago. Many well-known black  dancers were trained in her studios in  Chicago and New York City. In the  1950s she toured in Europe with her  company. She also choreographed  Broadway stage productions, operas,  and movies.</p><p>dunite Vdii-.nlt, 'do-.nlA Yellowish  green to green igneous rock composed almost entirely of olivine.

Naval ves�  sels and hundreds of civilian boats were used in the evacuation, which  began on May 26. When it ended on June 4, about 198,000 British and  140,000 French and Belgian troops had been saved. The operation�s suc�  cess was due to fighter cover by the RAF and (unintentionally) to Adolf  Hitler�s order of May 24 halting the advance of German armored forces  into Dunkirk.</p><p>Dunmore's War, Lord See Lord Dunmore's War</p><p>Dunne, Finley Peter (b.

A son of Irish  immigrants, Dunne began contributing Irish-dialect sketches to Chicago  newspapers in 1892. In these he created the character Martin Dooley, who  commented on current events in a rich Irish brogue. Mr. Dooley soon  became a force for clear thinking and tolerance in public affairs. Dunne  wrote more than 700 dialect essays, some of which were republished in  eight volumes, including Mr. Dooley in Peace and War and Mr. Dooley�s  Philosophy, from 1898 to 1919.</p><p>Dunnet Head Cape, northeastern Scotland.

He studied and taught at Oxford, where he joined the Fran�  ciscans, and later taught at the University of Paris, from which he was  briefly exiled for supporting Pope Boniface VIII in his quarrel with King  Philip IV. In 1307 he became professor of theology at Cologne, perhaps to  escape charges of heresy over his defense of the doctrine of the Immacu�  late Conception, which the Dominicans and secular authorities opposed.  His two major works are Ordinatio and Quaestiones quodlibetales, both  left unfinished at his death.</p><p>Dunstable Vdon-sto-boR, John (b. c. 1385, England�d.

After his death he came to be credited with the achieve�  ments of all his English contemporaries, including Leonel Power (c.  1380-1445). He left at least 50 compositions, all for three and four voices  and almost all sacred. Their full triadic harmony and frequent parallel  motion in the voices represented an important innovation that influenced  composers such as Guillaume Dufay and Gilles Binchois (c. 1400-60),  softening the austerity of 14th-century polyphony.</p><p>Dunstan of Canterbury, Saint (b. c. 909, near Glastonbury,  Eng.�d.

Under  King Eadred he served as minister of state, working to conciliate the  Danish section of the kingdom and reform the church. Dunstan was out�  lawed (955) under King Eadwig and went into exile in Flanders, but he  was recalled by King Edgar (957) and continued his reforms, restructur�  ing English monasticism on the continental model. He became archbishop  of Canterbury in 959.</p><p>duodenum X.du-o-'de-nom, du-'a-d 3 n-om\ First and shortest (9-11 in.,  or 23-28 cm) segment of the small intestine. It curves down and then up  from the pylorus of the stomach, where chyme enters it. Ducts from the  pancreas and gallbladder bring in bicarbonate to neutralize stomach acid,  pancreatic enzymes to further digestion, and bile salts to break up fats.  Nutrient absorption begins in the lower duodenum, which has a mucous  lining. Exposure to stomach acid makes the upper duodenum susceptible  to peptic ulcers, the duodenum�s most common problem. Compression of  the lower duodenum between the liver, pancreas, and major blood ves�  sels can require surgery.</p><p>Duparc NdtE-'parkX, (Marie-Eugene-) Henri (b. Jan. 21, 1848, Paris,  France�d. Feb. 12, 1933, Mont-de-Marsan) French song composer. He  studied music with Cesar Franck while also studying law. His composing  career lasted about 16 years; he stopped composing at age 36 for psy�  chological reasons. Highly self-critical, he destroyed an incomplete opera  and other works and acknowledged only 13 completed songs, including  �L�lnvitation au voyage,� �Phidyle,� �Testament,� and �Extase,� as his  lifetime oeuvre. Almost all the songs, universally admired, were origi�  nally for voice and piano; he later orchestrated eight of them.</p><p>Dupleix Vdte-'pleksR English \dii-'pleks\, Joseph-Francois (b. 1697,  Landrecies, France�d.

His father, a  director of the French East India Company, secured him an appointment in  1720 to the superior council of Pondicherry, capital of French India, and  in 1742 he was named governor-general of French India. He fought the  British in India during the War of the Austrian Succession (1744) and later  attempted to undermine the British position in southern India. His  schemes exhausted French finances, and he was recalled to France, dis�  credited, in 1754.</p><p>1910, Joliet, Ill., U.S.) U.S. dancer,</p><p>Katherine Dunham in Tropical Revue</p><p>(1945-46).</p><p>COURTESY OF THE DANCE COLLECTION, NEW YORK PUBLIC  LIBRARY, ASTOR, LENOX AND TILDEN FOUNDATIONS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>DuPont Co. &#x25BA; Diirer I 581</p><p>DuPont Co. in full E.l. du Pont de Nemours &amp; Co.

The company originally manufactured gun�  powder and other explosives. It was incorporated in 1899 after nearly a  century as a partnership, after which it began to diversify its product line,  partly through extensive acquisitions. DuPont developed nitrocellulose  plastics in 1915 and synthetic rubber in 1931 and later developed the fibres  nylon, Orion, Dacron, Kevlar, and Lycra, as well as Mylar film and Teflon  resin, among many other synthetics.

He later devoted  himself to landscape painting, becoming a founder of the Hudson River  school and one of the earliest U.S. artists to work directly from nature.  In 1826 he cofounded the National Academy of Design in New York City  and served as its president (1845-61).</p><p>Durango \du-Tai]-go\ State (pop., 2000: 1,448,661), north-central  Mexico. It covers 47,560 sq mi (123,181 sq km), and its capital is  Durango. The western portion of the state lies within the mineral-laden  Sierra Madre Occidental; semiarid plains, used for ranching, comprise the  eastern portion. The Nazas River, which flows about 375 mi (600 km), is  the largest in the state and is a main source of water for commercial agri�  culture. Along the river�s lower course is the Laguna cotton district, a  large state-operated cooperative that Durango city shares with Coahuila  state. First explored by Europeans in 1562, Durango shared the colonial  history of Chihuahua as a major part of Nueva Vizcaya; the two states  separated in 1823.</p><p>Durango officially Victoria de Durango City (pop., 2000:  427,135), capital of Durango state, north-central Mexico. It lies in a fer�  tile valley of the Sierra Madre, about 6,200 ft (1,890 m) above sea level.  North of the city is the Cerro del Mercado, a hill of nearly pure iron ore  representing one of the world�s largest deposits of that mineral. First  settled in 1556, Durango was the political and ecclesiastical capital of  Nueva Vizcaya, which included Durango and Chihuahua until 1823. The  city, long known as a health resort, is an important commercial and min�  ing centre.</p><p>Durant \du-'rant\, Will(iam James) and Ariel Ariel Durant orig.

(founded by David Buick in 1902)  in 1903-04, quickly reviving it. In 1908 he brought together several auto�  motive manufacturers to form the General Motors Co. He lost control of  the company two years later. With Louis Chevrolet (1878-1941) he  founded the Chevrolet Motor Co., which acquired control of General  Motors in 1915. As president of General Motors Corp. until 1920, he pre�  sided over its steady expansion.</p><p>Durante \d3-'ran-te\, Jimmy orig.

In the 1920s the team of Durante, Lou Clay�  ton, and Eddie Jackson starred in vaudeville and nightclubs; they appeared  on Broadway in Florenz Ziegfeld�s Show Girl (1929). Durante made his  film debut in Roadhouse Nights (1930) and over the next 30 years bright�  ened many films and musicals with his gravelly voice, malapropisms, and  warmhearted buffoonery. Nicknamed �Schnozzola� for his large nose, he  is remembered for ending his many radio and television programs with  the line �Goodnight, Mrs. Calabash, wherever you are.�</p><p>Duras \diE- , ras\, Marguerite orig. Marguerite Donnadieu (b.</p><p>April 4, 1914, Gia Dinh, Cochinchina�d. March 3, 1996, Paris, France)  French novelist, playwright, film director, and screenwriter. Indochina  was the setting for Duras�s first successful novel, The Sea Wall (1950).  Her writing grew increasingly minimal and abstract, and she is sometimes  associated with the nouveau roman (�new novel�) movement. Perhaps her  best-known novel is the semiautobiographical The Lover (1984, Prix Gon-  court; film, 1992), about a French teenage girl�s love affair with an older  Chinese man; she revised this work as The North China Lover (1991).  Her original screenplay for Hiroshima mon amour (1959) and her adap�  tation for film of her play India Song (1975) were highly acclaimed.</p><p>Durban City (pop., 1996: metro, area, 2,117,650) and chief seaport,  South Africa. Located on Natal Bay of the Indian Ocean, it was the site  of a European trading settlement from 1824 and was named Port Natal  by the traders. Land was ceded to them by the Zulu king Shaka, and the  Old Fort (now a museum) was built. Durban was founded in 1835 on the  site of Port Natal. In the 1840s the Boers clashed with the British over  control of Durban. One of the world�s major commercial ports, it is the  headquarters of South Africa�s sugar industry and a centre of diverse  manufacturing. Tourism is also important, based on the city�s proximity  to game and nature reserves and to beaches.</p><p>Durer VdiEr-9r,\ English Vdur-3r\, Albrecht (b.

He worked as a  draftsman in his father�s goldsmith  workshop before being apprenticed  at 15 to a painter and illustrator in his  native Niimberg. He opened his own  workshop c. 1494 and began produc�  ing woodcuts and copper engravings.</p><p>His extensive travel took him twice  to Italy; Italian influence can be seen  in such engravings as The Four  Witches (c. 1497) and Adam and Eve  (1504). He became known for his  penetrating half-length portraits and  self-portraits. In 1506, in Venice, he  completed his great altarpiece The  Feast of the Rose Garlands for the  German chapel in the church of San  Bartolommeo. Later important  graphic works include his famous  Passion series of copperplate  engravings (1507-13) as well as his  greatest engravings: St. Jerome in  His Study, Melencolia I and The  Knight, Death, and the Devil (1513-14).

It is on a  peninsula in the River Wear. This natural defensive site, fortified by Wil�  liam I (the Conqueror) against the Scots, became a seat of the feudal  prince-bishops of Durham. Medieval Durham was a place of pilgrimage,  holding the remains of St. Cuthbert in its cathedral (begun in 1093). The  bishops of Durham helped establish the city as an educational centre. It  is the site of the Gulbenkian Museum of Oriental Art and Archaeology,  part of the University of Durham.</p><p>Durham Vdor-onA Administrative (pop., 2001: 493,470), geographic,  and historic county, northeastern England. Adjacent to the North Sea  coast, it includes the city of Durham. The northern part of the county is  cut by the valleys of the Rivers Wear and Tees; the Tees lowlands extend  across the south. Under the Romans the region was a military outpost  associated with Hadrian's Wall. Durham was later incorporated into the  Saxon kingdom of Northumbria. It was unimportant economically until  the 19th century, when exploitation of its coalfields, now exhausted, made  it a key area of industrial growth in Britain. The area is now a centre of  light industry.</p><p>Durham, John George Lambton, 1 st earl of (b. April 12,1792,  London�d. July 28, 1840, Cowes, Isle of Wight, Eng.)

In 1838  he was appointed governor-general and lord high commissioner of  Canada. He appointed a new executive council to placate the rebellious</p><p>French Canadians of Lower Canada (later Quebec). Criticized in England  for his action, he resigned.

The spherical fruit has  a hard spiny shell and contains five oval compartments, each filled with  an edible, cream-coloured, custardlike pulp, in which are embedded one  to five chestnut-sized seeds, which are edible if roasted. The ripe fruits  are eaten by many animals. Though the durian has a mild, sweet flavour,  it also has a pungent foul odour. It is seldom exported.</p><p>Durkheim \dmr-'kem\, Emile (b. April 1858, Epinal, France�d. Nov.  15, 1917, Paris) French social scientist. He developed a vigorous meth�  odology combining empirical research with sociological theory and is  widely regarded as the founder of the French school of sociology.  Durkheim was greatly influenced by philosopher Auguste Comte, and his  sociological reflections, never remote from the moral philosophy he was  schooled in, were first expressed in The Division of Labor in Society  (1893) and Suicide (1897). In his view, ethical and social structures were  endangered by technology and mechanization. The division of labour pro�  duced alienation among workers, and the increased prosperity of the late  19th century generated greed and passions that threatened the equilibrium  of society. Durkheim drew attention to anomie, or social disconnectedness,  and studied suicide as a decision to renounce life. Following the Dreyfus  affair, he came to regard education and religion as the most potent means  of reforming humanity and molding new social institutions. His Elemen�  tary Forms of the Religious Life (1915) is an anthropological study�  centring largely on totemism �of the origins and functions of religion,  which Durkheim saw as expressing the collective conscience of a soci�  ety and producing social solidarity. He also wrote influential works on  sociological method. He taught at the Universities of Bordeaux (1887�  1902) and Paris (1902-17).

Durocher played for various teams from 1928 to  1938, distinguishing himself by his sharp fielding at shortstop. He gained  notoriety as the cheeky, contentious manager of the Brooklyn Dodgers  (1939-46, 1948); he was suspended from managing for the entire 1947  season for �conduct detrimental to baseball,� a vague charge that was  based upon Durocher�s reputation for gambling and fast living. He man�  aged the New York Giants 1948-55, left to become a commentator,  returned to the game as a coach for the Los Angeles Dodgers (1961-64),  and managed the Chicago Cubs (1966-72) and the Houston Astros (1972-  73). He is credited with the observation �Nice guys finish last� (what he  actually said was, �The nice guys over there are in seventh place�).</p><p>Durrani, Ahmad Shah See Ahmad Shah Durrani</p><p>Durrell Vdo-roL, Lawrence (George) (b.

He is  best known for the tetralogy The Alexandria Quartet, composed of the  novels Justine (1957), Balthazar (1958), Mountolive (1958), and Clea  (1960), which explore the erotic lives of a group of exotic characters in  Alexandria, Egypt. His poetry�including Cities, Plains and People  (1946)�and nonfiction books about locales�including Prospero�s Cell  (1945), Reflections on a Marine Venus (1953), and Bitter Lemons (1957),  describing three Greek islands�are often considered his best works.</p><p>Durrenmatt \'diEr-9n- l mat\, Friedrich (b.

His  plays, showing the influence of Bertolt Brecht as well as the Theatre of the  Absurd, were central to the post-1945 revival of the German theatre. In  his first three plays, All as It Is Written (1947), The Marriage of Mr. Mis�  sissippi (1952), and An Angel Comes to Babylon (1953), he took comic  liberties with historical facts to present parables about modern life. His  play The Visit (1956) and the modern morality play The Physicists (1962)  earned him international acclaim. After 1970 he wrote adaptations, detec�  tive novels, radio plays, and essays.

After seeing a gasoline engine at a state fair, he  designed a gasoline-powered automobile, and in 1893 he and his brother  Frank constructed the first U.S. automobile, which they drove success�  fully on the streets of Springfield, Mass. In Chicago in 1895, Frank drove  an improved model to win the first U.S. auto race. In 1896 their company  manufactured the first commercially produced U.S. automobiles; 13 cars  were sold before the company failed and the brothers separated. Both  started new automobile manufacturing ventures; Frank later developed the  Stevens-Duryea limousine, which was produced into the 1920s.</p><p>Dusan, Stefan See Stefan Dusan</p><p>Duse Ydu-za\, Eleonora (b.

Although  it suffered considerably in the Thirty Years' War and the War of the Span�  ish Succession, it later revived. It was transferred to Prussia in 1815 and  grew rapidly with the establishment of iron and steel industries in the  1870s. Heavily damaged in World War II, its old buildings were repaired  and new ones erected. It is the site of the first German skyscraper, the  Wilhelm-Marx-Haus (1924).

It was first identified in the U.S. in 1930, and  an eradication campaign could not stop its spread into regions wherever  the very susceptible American elm ( Ulmus americana) grew. The leaves  on one or more branches of a stricken tree suddenly wilt, turn dull green  to yellow or brown, curl, and may drop early. Because symptoms are eas�  ily confused with other diseases, positive diagnosis is possible only  through laboratory culturing. The fungus can spread up to 50 ft (15 m)  from diseased to healthy trees by natural root grafts. Overland, the fun�  gus normally is spread by the European elm bark beetle ( Scolytus mul-  tistriatus ; see bark beetle), less commonly by the American elm bark beetle  (Hylurgopinus rufipes).

He reduced the size of the  military and organized the Tontons Macoutes (�Bogeymen�), a private  force that terrorized and assassinated alleged foes of his regime. He played  on the culture of vodun to intimidate the opposition as well. Promoting a  cult of his person as the semidivine embodiment of the nation, he declared  himself president for life in 1964. His regime�s corruption and despotism  isolated Haiti, the poorest country in the hemisphere, from the rest of the  world. His 19-year-old son, Jean-Claude Duvalier (�Baby Doc�; b. 1951),  succeeded him on his death.

The DVD represents the second generation of compact-disc  (CD) technology. Like a CD drive, a DVD drive uses a low-power laser  to read digitized (binary) data that have been encoded onto the disc in the  form of tiny pits. Because it uses a digital format, a DVD can store any  kind of data, including movies, music, text, and graphical images. DVDs  are available in single- and double-sided versions, with one or two layers  of information per side. Single-sided DVDs have become standard media  for recorded motion pictures, largely replacing videotape in the home  market. A double-sided, dual-layer version can store about 30 times as  much information as a standard CD. DVDs are made in a ROM (read�  only memory) format as well as in erasable (DVD-E) and recordable  (DVD-R) formats. Though DVD players can usually read CDs, CD play�  ers cannot read DVDs.

He played viola  in a theatre orchestra, often under the Czech nationalist composer Bedrich  Smetana, and eventually found employment that left him ample time for  composition. Johannes Brahms assisted in getting Dvorak�s works pub�  lished, and by 1880 his fame had spread throughout Europe. While serv�  ing as director of New York�s new National Conservatory of Music  (1892-95) he composed the symphony From the New World (1893), his  best-known work, which is thought to be based on black spirituals and  other American influences.

Belief in such spirits was common in eastern Europe  in the 16th-17th century. Individuals thought to be possessed by a dyb�  buk were taken to a ba'al shem, who would carry out a rite of exorcism. The  mystic Isaac ben Solomon Luria helped promote belief in dybbukim with  his doctrine of the transmigration of souls. The folklorist S. Ansky  depicted such a spirit in his classic Yiddish drama The Dybbuk (c. 1916).</p><p>Dyck, Anthony Van See Anthony Van Dyck</p><p>dye Any of a class of intensely coloured complex organic compounds  used to colour textiles, leather, paper, and other materials. Dyes known  to the ancients came from plants such as indigo and madder (see madder  family) or from the shells of mollusks; today most dyes are made from  coal tar and petrochemicals. The chemical structure of dyes is relatively  easy to modify, so many new colours and types of dyes have been syn�  thesized. Dye molecules are deposited from solution onto materials in  such a way that they cannot be removed by the original solvent. Fibre-  reactive dyes form a covalent bond with the fibre. Other dyes require prior  application of a mordant, an inorganic material that causes the dye to pre�  cipitate as an insoluble salt. Another technique is vat dyeing, in which a  soluble colourless compound is absorbed by the fibres, then oxidized (see  oxidation-reduction) to the insoluble coloured compound, making it  remarkably resistant to the fading effects of washing, light, and chemi�  cals.

He grew up in the  iron-range town of Hibbing, Minn., adopted the name of the poet Dylan  Thomas, and traveled to New York in search of idol Woody Guthrie. In the  early 1960s he performed professionally in Greenwich Village coffee�  houses and released albums that made him the darling of critics and folk  music devotees. �Blowin� in the Wind� and �The Times They Are  a-Changin�� became anthems of the civil rights movement. In 1965 he  adopted electrically amplified instruments and the rhythms of rock and  roll in a major departure. The landmark albums Highway 61 Revisited  (1965) and Blonde on Blonde (1966) established him as a leading figure  in rock music, and his lyrics, influenced partly by the Beat movement,  brought poetic complexity to pop music. After a motorcycle accident in  1966, he underwent another musical turnabout and released several  albums (notably Nashville Skyline, 1969) characterized by country music  elements and a muted, reflective tone. Among the most praised of his  many later albums are Blood on the Tracks (1975), Time Out of Mind  (1997) and Love and Theft (2001). He is perhaps the most admired and  influential American songwriter of his time.</p><p>dynamics Branch of mechanics that deals with the motion of objects in  relation to force, mass, momentum, and energy. Dynamics can be divided  into two branches, kinematics and kinetics. The foundations of dynamics  were laid by Galileo, who derived the law of motion for falling bodies  and was the first to recognize that all changes of velocity of a body are  the result of forces. Isaac Newton formulated this observation in his sec�  ond law of motion (see Newton's laws of motion).</p><p>dynamite Blasting explosive, patented in 1867 by Alfred P. Nobel.

It is character�  ized by inflammation, abdominal pain and straining, and diarrhea, often  containing blood and mucus. Dysentery is spread in food or water con�  taminated by feces, often by infected individuals with unwashed hands.  Bacillary dysentery (shigellosis), caused by Shigella bacteria, may be mild  or may be sudden, severe, and fatal. Fluid loss causes dehydration.  Advanced stages include chronic large-intestine ulceration. It is treated  with antibiotics, fluid replacement, and sometimes blood transfusion.  Amoebic (or amebic) dysentery, caused by the amoeba Entamoeba his�  tolytica, has two forms, one much like bacillary dysentery and the other  chronic and intermittent, sometimes with large-intestine ulcerations. It is  treated with drugs that kill the amoeba.</p><p>dyslexia \dis-'lek-se-o\ Chronic neurological disorder causing inability  or great difficulty in learning to read or spell, despite normal intelligence.  It inhibits recognition and processing of graphic symbols, particularly  those pertaining to language. Symptoms, including very poor reading  skills, reversed word and letter sequences, and illegible handwriting, usu�  ally become evident in the early school years. With early recognition and  specialized approaches to teaching reading, most dyslexics can learn to  read. Anomalies have recently been found in reading-related pathways in  the brains of dyslexic persons.</p><p>dysmenorrhea N.dis-.me-no-'re-sV Pain or cramps before or during  menstruation. In primary dysmenorrhea, caused by endocrine imbalances,  severity varies widely. Irritability, fatigue, backache, or nausea may also  occur. Long assumed to be psychosomatic, it is now known to be due to</p><p>excess prostaglandins, which contract the uterus, causing cramps. Pain  relievers that block prostaglandin formation can decrease its severity,  which may also be eased after childbearing. Secondary dysmenorrhea is  caused by other disorders, including genital obstructions, pelvic inflam�  mation, infection, polyps, or tumours. Treatment is directed toward the  underlying disorder.</p><p>dysphasia See aphasia</p><p>dysplasia \dis-'pla-zho\ Abnormal formation of a bodily structure or  tissue, usually bone, that may occur in any part of the body.

After early training at  the Ecole des Beaux-Arts in Paris (1866-70), he spent most of his life in  his native Philadelphia. He reinforced his study of the live model at the  Pennsylvania Academy of the Fine Arts by studying anatomy at a medi�  cal college. The Gross Clinic (1875), depicting a surgical operation, was  too realistic for his contemporaries but is now seen as his masterpiece.  In 1876 he began teaching at the Pennsylvania Academy, but he was</p><p>forced to resign in 1886 for working with nude models in mixed classes.  In addition to numerous portraits, he painted boating and other outdoor  scenes that reflect his fascination with the human body in motion. His  interest in locomotion led him to the sequential photography of Eadweard  Muybridge, and he began producing photographs and sculpture as well as  paintings. Perhaps the most outstanding U.S. painter of the 19th century,  his work inspired the trend of realism in American painting in the early  20th century.</p><p>Eales, John (b.

The outer ear directs sound vibrations  through the auditory canal to the eardrum, which is stretched across the  end of the auditory canal and which transmits sound vibrations to the  middle ear. There a chain of three tiny bones conducts the vibrations to  the inner ear. Fluid inside the cochlea of the inner ear stimulates sensory  hairs; these in turn initiate the nerve impulses that travel along the audi�  tory nerve to the brain. The inner ear is also an organ of balance: the sen�  sation of dizziness that is felt after spinning is caused when fluid inside  the inner ear�s semicircular canals continues to move and stimulate sen�  sory hairs after the body has come to rest. The eustachian tube connects  the middle ear with the nasal passages; that connection allows the com�  mon cold to spread from the nasal passages to the middle ear, especially  in infants and small children. The most common cause of hearing loss is  otosclerosis, a surgically correctable disease in which one of the bones of  the middle ear loses its capacity to vibrate. See also deafness, otitis.

Vibrations are transmitted via  three small bones (hammer, anvil, stirrup) to the membranous oval window, which  links the middle ear to the inner ear. The cochlea is a coiled, fluid-filled tube lined  with sensory hairs. Vibrations in the oval window cause movement of the cochlear  fluid, stimulating the hairs to initiate impulses that travel along a branch of the audi�  tory nerve to the brain. The eustachian tube, running from the middle ear to the  nasopharynx, equalizes pressure between the middle and outer ear.

Believed to be about  4.6 billion years old, it is some 92,960,000 mi (149,600,000 km) from the  Sun. It orbits the Sun at a speed of 18.5 mi (29.8 km) per second, mak�  ing one complete revolution in 365.25 days. As it revolves, it rotates on  its axis once every 23 hours 56 minutes 4 seconds. The fifth largest planet  of the solar system, it has an equatorial circumference of 24,902 mi (40,076  km). Its total surface area is roughly 197,000,000 sq mi (509,600,000 sq  km), of which about 29% is land. Earth�s atmosphere consists of a mix�  ture of gases, chiefly nitrogen and oxygen. Its only natural satellite, the  Moon, orbits the planet at a distance of about 238,860 mi (384,400 km).  Earth�s surface is traditionally subdivided into seven continental masses:  Africa, Antarctica, Asia, Australia, Europe, North America, and South  America. These continents are surrounded by four major bodies of water:  the Arctic, Atlantic, Indian, and Pacific oceans. Broadly speaking. Earth�s  interior consists of two regions: a core composed largely of molten, iron-  rich metallic alloy; and a rocky shell of silicate minerals comprising both  the mantle and crust (see also Moho; uthosphere). Fluid motions in the  electrically conductive outer core generate a magnetic field around Earth  that is responsible for the Van Allen radiation belts. According to the theory  of plate tectonics, the crust and upper mantle are divided into a number  of large and small plates that float on and travel independently of the lower  mantle.

Space around Earth contains vast  numbers of objects in a range of sizes, but only the largest, which strike  very rarely on average, are thought to pose a great danger. Scientists  believe such an impact caused the mass extinction of dinosaurs and other  species at the end of the Cretaceous Period 65 million years ago. In addi�  tion to creating tremendous immediate destruction, a large impact could  throw great clouds of debris into the atmosphere, cutting off sunlight and  causing a prolonged temperature drop�an �impact winter� (similar to a  nuclear winter) that would kill plant life and bring on worldwide famine.  The amount of damage depends primarily on the colliding object�s mass  and relative velocity. The energy released, expressed in millions of tons  (megatons) of TNT, falls between about 10 megatons and 1 billion mega�  tons, corresponding to objects roughly 160 ft (50 m) to 12 mi (20 km)  across. The last destructive impact known, the Tunguska event, occurred  over Siberia in 1908. Since the 1990s, search programs have scanned for  objects on possible collision courses.

The �size,� or magnitude, of earthquakes is usually expressed  in terms of the Richter scale, which assigns levels from 1.0 or lower to 8.0  or higher. The largest quake ever recorded (Richter magnitude 9.5)  occurred off the coast of Chile in 1960. The �strength� of an earthquake is  rated in intensity scales such as the Mercalli scale, which assigns quali�  tative measures of damage to terrain and structures that range from �not</p><p>felt� to �damage nearly total.� The most destructive quake of modem  times occurred in 1976, when the city of Tangshan, China, was leveled and  more than 250,000 people killed.

Earthquakes exert lateral as well as vertical forces, and a struc�  ture�s response to their random, often sudden motions is a complex task  that is just beginning to be understood. Earthquake-resistant structures  absorb and dissipate seismically induced motion through a combination  of means: damping decreases the amplitude of oscillations of a vibrating  structure, while ductile materials (e.g., steel) can withstand considerable  inelastic deformation. If a skyscraper has too flexible a structure, then tre�  mendous swaying in its upper floors can develop during an earthquake.

Some U.S. states  permit the creation of an easement by prescription (acquisition of an  interest), as when one person makes continuous use of another�s land for  some specified period of time (e.g., 20 years). Utility companies often  own easements in gross; these are not dependent on ownership of the sur�  rounding estate. Numerous other kinds of easements have been important  in Anglo-American law.

It consists of the historic  counties of Norfolk and Suffolk and parts of Cambridgeshire and Essex, and  its traditional centre is the city of Norwich. The easternmost area in  England, it has been settled for thousands of years. Colchester, the oldest  recorded town in England, was important in pre-Roman and Roman times.  East Anglia was one of the kingdoms of Anglo-Saxon England, and it  was ruled by Danes in the 9th century. During the medieval period it was  known for its woolen products, but the region�s modern economy is pre�  dominantly agricultural. Along the coast are many important fishing ports  and holiday resorts.</p><p>East Asian arts Visual, literary, and performing arts of China, Korea,  and Japan. Painting and calligraphy are considered the only true fine arts  in China because they alone require no physical labour and have no physi�  cal function. Sculpture is considered to be a craft, as are bronze casting,  carving, and the making of pottery, textiles, metalwork, and lacquerware.  Chinese architecture is characterized by timber buildings, and a building  typically consists of a platform, a post-and-lintel frame, a system of roof�  supporting brackets, and a heavy, sloping roof. Japanese visual arts have  been strongly influenced by three elements: Chinese visual arts, indig�  enous themes and traditions, and Buddhist iconography. The Horyu  Temple (7th century) initiated the distinctive Japanese architectural  approach: asymmetrical layouts following the contours of the land. Japa�  nese artists� fascination with abstraction from nature is most notable in  screen and panel paintings of the 16th-18th centuries and the polychrome  woodcut, which evolved into the popular ukiyo-e print. Among the  remarkable features of Korean art might be noted the use of stone in  architecture and sculpture and the development of an outstanding celadon  glaze. Chinese literature has the longest continuous history of any litera�  ture in the world (more than 3,000 years). It is inextricably bound to the  development of the characters of the written language it has shared with  both Korea and Japan. Korean literature includes an oral tradition of bal�  lads, legends, mask plays, puppet-show texts, and p'ansori (�story sing�  ing�) texts and a strong written tradition of poetry (notably hyangga and  sijo forms). Like Korean literature, Japanese literature owes a debt to  Chinese, since neither country had its own written language (though Japa�  nese syllabary systems emerged about 1000, and Korean Hangul was  developed in the 15th century). The earliest Japanese literature dates to  the 7th century; in addition to its several literary monuments such as The  Tale of Genji, Japanese poetry (particularly in the haiku form) is known  throughout the world for its exquisite delicacy. Despite a different basis  for its establishment, the East Asian music system, like Western music,  developed a pentatonic scale based on a 12-tone vocabulary. The preferred  size of the East Asian ensemble is small, and compositions emphasize  melody and rhythm over harmonics. In the related categories of East Asian  dance and theatre, it is noteworthy that in the East Asian countries, music,  dance, and drama are typically linked, and there is little evidence of sepa�  rate evolution of form. The several forms of East Asian performing arts  include both masked and unmasked dances, masked dance theatre (as in  Japanese no and Korean sandae ), danced processionals, dance opera  ( jingxi , or �Peking,� and other forms of Chinese opera), shadow theatre,  puppet theatre, and dialogue plays with music and dance (e.g., Japanese  kabuki).

English chartered com�  pany formed for trade with East and Southeast Asia and India, incorpo�  rated in 1600. It began as a monopolistic trading body, establishing early  trading stations at Surat, Madras (now Chennai), Bombay (Mumbai), and  Calcutta (Kolkata). Trade in spices was its original focus; this broadened  to include cotton, silk, and other goods. In 1708 it merged with a rival</p><p>and was renamed the United Co. of Merchants of England Trading to the  East Indies. Becoming involved in politics, it acted as the chief agent of  British imperialism in India in the 18th�19th century, exercising substan�  tial power over much of the subcontinent. The company�s activities in  China in the 19th century served as a catalyst for the expansion of Brit�  ish influence there; its financing of the tea trade with illegal opium exports  led to the first Opium War (1839�42). From the late 18th century it gradu�  ally lost both commercial and political control; its autonomy diminished  after two acts of Parliament (1773, 1774) established a regulatory board  responsible to Parliament, though the act gave the company supreme  authority in its domains. It ceased to exist as a legal entity in 1873.

Under the administration of forceful govemors-general, it was able  to defeat the British fleet and largely displace the Portuguese in the East  Indies. It prospered through most of the 17th century but then began to  decline as a trading and sea power; it was dissolved in 1799.

In constant competition with the already-established  Dutch East India Co., it mounted expensive expeditions that were often  harassed by the Dutch. It also suffered in the French economic crash of  1720, and by 1740 the value of its trade with India was half that of the  English East India Co. Its monopoly over French trade with India was  ended in 1769, and it languished until its disappearance in the French  Revolution.</p><p>East Pacific Rise Submarine linear mountain range on the floor of the  South Pacific Ocean, roughly paralleling the western coast of South  America.

In Western churches  it falls on a Sunday between March 22 and April 25, depending on the  date of the first full moon after the spring equinox. This time span was  fixed after the Council of Nicaea (ad 325). In the Eastern Orthodox cal�  endar, which uses a different calculation, it often falls later. A joyful fes�  tival and a time of redemption, Easter brings an end to the long period of  penance that constitutes Lent. The word is sometimes said to have been  derived from Eostre, a Germanic goddess of spring, but other origins of  the term more closely associated with Christian traditions have been pro�  posed. Easter has acquired a number of religious and popular customs.  The Easter worship service is one of the high points of the Christian cal�  endar, and since the late 2nd century Easter has also been a time for bap�  tism.

Its adherents live mostly in  Greece, Russia, the Balkans, Ukraine, and the Middle East, with a large  following in North America and Australia. The titular head of Eastern  Orthodoxy is the ecumenical patriarch of Constantinople (Istanbul), but  its many territorial churches (including the huge Russian Orthodox church  and the Greek Orthodox church) are governed autonomously by head bish�  ops or patriarchs, who must be unmarried or widowed even though lower  orders of the clergy may marry. Eastern Orthodoxy also boasts a strong  monastic tradition. The separation of the Eastern churches from the West�  ern, or Latin, branch began with the division of the Roman Empire into  two parts under Constantine I. A formal break was made in 1054 (see  Schism of 1054). Doctrinally, Eastern Orthodoxy differs from Roman  Catholicism in that it does not accept the primacy of the pope or the clause  in the Western creed that states that the Holy Spirit proceeds from both the  Father (God) and the Son (Jesus). The Orthodox church accepts the deci�  sions of the seven ecumenical councils as well as several later ones. It  maintains that there are seven sacraments and has a worship service that  is theologically and spiritually rich. In the early 21st century, Eastern  Orthodoxy had more than 200 million adherents worldwide.</p><p>Eastern rite church or Eastern Catholic church Any of several  Eastern Christian churches that trace their origins to ethnic or national  Eastern churches but are united with the Roman Catholic church (see  Roman Catholicism). A few of these churches became associated with  Rome in the 12th century, but most trace their origins to the failure to  unite Eastern and Western churches at the Council of Ferrara-Florence in  1439 or to churches that rejoined Rome in the 16th century or later. East�  ern rite churches acknowledge the authority of the pope but are allowed  to use their own ancient liturgies and to maintain rites and customs more  typical of Eastern Orthodoxy, such as allowing priests to marry and admit�  ting infants to Holy Communion. The Eastern rite includes the Ukrainian  Orthodox church, the Maronite Church, and some Armenians, Ruthenians,  and Melchites (in Syria). Today Eastern Catholics number more than 12  million.</p><p>Eastern Woodlands Indian Any member of the various North  American Indian peoples of the largely wooded area stretching east from  the Mississippi River valley to the Atlantic coastline and extending north  into Canada and south as far as what are now the U.S. states from Illi-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Eastman &#x25BA; eccentric I 591</p><p>nois to North Carolina. The Indians in this region spoke Iroquoian, Algon-  quian, and Siouan languages. The heaviest population concentrations were  near or along the seacoast, lakes, ponds, marshes, creeks, and rivers. There  animals could be hunted, fish caught, birds taken, leaves, seeds, and roots  of wild plants gathered, shellfish collected, and crops grown. Certain areas  were favoured with resources not found elsewhere in the region.

In 1889  he introduced transparent film, and in 1892 he reorganized his Rochester  company as the Eastman Kodak Co. The introduction of the first Kodak  (a coined word that became a trademark) camera helped promote large-  scale amateur photography. By 1927 Eastman Kodak had a virtual  monopoly of the U.S. photographic industry, and it has remained one of  the largest American companies in its field.

After receiving his doctorate from the Royal College  of Science, he became an early advocate of Oliver Heaviside�s theory that  an upper layer of the atmosphere reflects radio waves, enabling their  transmission over long distances. In 1912 he suggested that solar radia�  tion accounted for wave-propagation differences between day and night.</p><p>Ecclesia \3-'kle-ze-3\ (Greek, ekklesia : �gathering of those summoned�)  In ancient Greece, the assembly of citizens in a city-state. The Athenian  Ecclesia already existed in the 7th century; under Solon it consisted of  all male citizens age 18 and older. It controlled policy, including the right  to hear appeals in the public court, elect archons, and confer special  privileges. After discussion, members voted by a show of hands; a simple  majority determined the results. The body could not initiate new business,  since motions had to originate in the boule. Ecclesias existed in most Greek  city-states through Roman times, though their powers faded under the  empire.</p><p>ecclesiastical heraldry Arms associated with the administrative and  collegiate bodies of a church, particularly the Anglican, Roman Catholic,  and Presbyterian churches.

A writer for the newspaper of the  Republican People�s Party (RPP), he was elected as a RPP member to the  Turkish parliament in 1957. As minister of labour (1961-65), he made the  strike a legal weapon for labour for the first time in Turkish history. He  became head of the RPP in 1972 and served as prime minister of Turkey,  first in the 1970s and later from 1999 to 2002. As head of government,  he declared an amnesty for all political prisoners and in 1974 authorized  Turkey�s military intervention in Cyprus after the Greek-led coup on that  island.</p><p>Echegaray \,a-cha-ga-'rl\ (y Eizaguirre) , Jose (b. April 19, 1832,  Madrid, Spain�d. Sept. 4, 1916, Madrid) Spanish dramatist. A math�  ematics professor in his early life, he later held government positions,  including minister of finance, and helped develop the Banco de Espana.  His first play, The Checkbook, was not produced until he was 42 years  old; from then on he wrote an average of two plays a year for the rest of  his life. These melodramas, now forgotten, were very popular in his day,  and he was admired for his fertile imagination and his skillful stage  effects. With Frederic Mistral, he won the 1904 Nobel Prize for Literature.</p><p>echidna \i-'kid-n3\ or spiny anteater any of three species of egg-  laying mammals (monotremes) of the  family Tachyglossidae. Echidnas are  stocky and virtually tailless. They  have strong-clawed feet and spines  on the upper part of the brownish  body. The snout is narrow, the mouth  very small, and the tongue long and  sticky for feeding on termites, ants,  and other invertebrates in the soil.</p><p>The short-beaked echidna common  in Australia and Tasmania is 12-21  in. (30-53 cm) long. Two species of  long-beaked echidna live only on the  island of New Guinea. They are  18-31 in. (45-78 cm) long and have  a prominent downward-pointing snout. They are valued for their meat and  are declining in numbers. Echidnas exude milk from mammary openings  on the skin, and the young lap it up. See also anteater; pangolin; hedgehog.</p><p>echinacea \,e-ki-'na-sh3, ,e-ki-'na-se-3\ Any member of the coneflower  genus Echinacea. Commonly called the purple coneflower, echinacea is  used as a border plant. The leaves and roots are used in herbal remedies  to boost the immune system and in the treatment of colds and flu.</p><p>echinoderm \i-'kl-n3-,d3rm\ Any of various marine invertebrates (phy�  lum Echinodermata) characterized by a hard spiny covering, a calcite  skeleton, and five-rayed radial body symmetry. About 6,000 existing spe�  cies are grouped in six classes: feather stars and sea lilies (Crinoidea),  starfishes (Asteroidea), brittle stars and basket stars (Ophiuroidea), sea  urchins (Echinoidea), sea daisies (Concentricycloidea), and sea cucumbers  (Holothurioidea). Echinoderms are found in all the oceans, from the inter�  tidal zone to the deepest oceanic trenches. Most species have numerous  tube feet that are modified for locomotion, respiration, tunneling, sensory  perception, feeding, and grasping. Movement of water through a water  vascular system composed of five major canals and smaller branches con�  trols extension and retraction of the tube feet. Most echinoderms feed on  microscopic detritus or suspended matter, but some eat plants.</p><p>Echo In Greek mythology, a mountain nymph transformed into a disem�  bodied voice. According to Ovid, her chatter distracted Hera from the infi�  delities of Zeus, and the goddess punished her by depriving her of  independent speech, rendering her able only to repeat the last words spo�  ken by another. When Narcissus failed to requite her love, she faded away  into a voice only.</p><p>echolocation V.e-ko-lo-'ka-shsnV Physiological process for locating  distant or invisible objects (such as prey) by emitting sound waves that  are reflected back to the emitter by the objects. Echolocation is used by  an animal to orient itself, avoid obstacles, find food, and interact socially.  Most bats employ echolocation, as do most, if not all, toothed whales (but  apparently no baleen whales), a few shrews, and two kinds of birds (oil-  birds and certain cave swiftlets). Echolocation pulses consist of short  bursts of sound at frequencies ranging from about 1,000 Hz in birds to at  least 200,000 Hz in whales. Bats use frequencies from about 30,000 to  about 120,000 Hz.</p><p>Eck, Johann orig. Johann Maier (b. Nov. 13, 1486, Egg,  Swabia�d. Feb. 10, 1543, Ingolstadt, Bavaria) German Roman Catholic  theologian. He was ordained in 1508, became a doctor of theology in  1510, and began a lifelong career at the University of Ingolstadt. Initially  friendly with Martin Luther, Eck assailed Luther�s Ninety-five Theses as  heretical. In 1519 he debated Luther and Andreas Karlstadt (c. 1480-  1541), and Leo X commissioned Eck to publish and enforce the papal bull  condemning the Theses. Eck�s treatise Enchiridion Against the Lutherans  (1525) summarized contested Catholic beliefs, Protestant objections to  them, and Catholic answers to the objections; it was Eck�s most popular  work and the best-known Catholic polemical handbook of the 16th cen�  tury.</p><p>Eckert, J(ohn) Presper, Jr. (b.

Mauchly built a digi�  tal computer, the ENIAC, which contained a primitive form of the cir�  cuitry used in present-day high-speed computers. In 1949 they introduced  the BINAC (Binary Automatic Computer). Their third model, UNIVAC I  (Universal Automatic Computer), found many uses in commerce.

He was one of the first to apply IBM punched-card  equipment to the reduction of astronomical data and to describe planetary  orbits numerically. As director of Columbia University�s Watson Scien�  tific Computing Laboratory from 1945, he used computers to determine  precise planetary positions and made major contributions to the study of  the orbit of the Moon, one of whose craters is named for him.</p><p>Eckhart, Meister orig.

A  Dominican from age 15, he studied theology at Cologne and Paris and  became a popular preacher and teacher. In his mid 30s he served as vicar  of Thuringia. His mystical writings examined the relationship between  God and humanity; he pictured the soul achieving complete union with  God and posited something (Godhead) beyond God. He took up a pro�  fessorship in Cologne in his 60th year; shortly thereafter he was charged  with heresy on several points in his works. He died before he could rebut  a second charge.</p><p>Eckstine \ l ek-,stln\, Billy orig. William Clarence Eckstein (b.</p><p>July 8, 1914, Pittsburgh, Pa., U.S.�d.

Disbanding the group in 1947, he  achieved greater popular success as a solo performer, specializing in bal�  lads that featured his deep, resonant baritone. He was one of the greatest  interpreters of popular song and blues in jazz.</p><p>eclampsia See preeclampsia and eclampsia</p><p>eclipse The passage of all or part of one celestial body into the shadow  of another, the eclipsing body. Observers on Earth experience two major  types�lunar eclipses and solar eclipses�each of which involves the Sun  and the Moon. The type observed depends on whether Earth is the eclips�  ing body or the body in shadow. In a lunar eclipse the orbit of the Moon  carries it through Earth�s shadow. Observers see the full Moon dim con�  siderably, but it remains faintly visible. In a solar eclipse the Moon is the  eclipsing body, passing between Earth and the Sun while casting a trav�  eling shadow across Earth�s lighted surface. Observers along the shad�  ow�s path see a total or partial obscuring of the Sun�s disk by the Moon�s  silhouette. The shadow cast by the eclipsing body consists of the central  umbra, into which no direct sunlight penetrates (total eclipse), and the  encircling penumbra, reached by light from only part of the Sun�s disk  (partial eclipse). Solar eclipses visible from different parts of Earth occur  two to five times a year; one total solar eclipse occurs in most years. When  Earth is closest to the Sun and the Moon farthest from Earth, the Moon�s  silhouette may fall entirely within the Sun�s disk, with a ring of the disk  visible around it (annular eclipse). Lunar eclipses occur twice in most  years. Other kinds of eclipses include those of the Sun by Mercury or  Venus (transits), of distant stars by planets or planetary satellites (occul-  tations), and of stars by orbiting companion stars (see eclipsing variable  star). See also Baily's beads. See illustration above.</p><p>eclipsing variable star or eclipsing binary Binary star in an orbit  whose plane passes through or very near Earth. An observer on Earth sees  one star pass periodically in front of the other and diminish its light  through an eclipse. The star Algol, in the constellation Perseus, was the  first such star recognized (1782); thousands are now known. By combin�  ing the brightness variations with spectroscopic information for both stars,  astronomers can determine the mass and size of each star. See also vari�  able STAR.</p><p>ecliptic \i-�klip-tik\ Great circle that is the apparent path of the Sun  among the constellations in the course of a year; from another viewpoint,  the projection on the celestial sphere of the orbit of Earth around the Sun,  which intersects the plane of the celestial equator at the vernal and autum�  nal EQUiNOXes. The constellations of the zodiac are arranged along the  ecliptic.</p><p>eclogite Vek-l3-jlt\ Any member of metamorphic rocks whose original  composition is similar to that of basalt. Eclogites consist primarily of  green pyroxene (omphacite) and red garnet (pyrope), with small amounts  of various other minerals such as kyanite and rutile. These minerals in the  eclogite are the result of reactions in originally igneous minerals having  been subjected to extremely high pressures and moderate to relatively  high temperatures.</p><p>eclogue Vek-.log, 'ek-,lag\ Short, usually pastoral, poem in the form of  a dialogue or soliloquy (see pastoral). The eclogue as a pastoral form first</p><p>appeared in the idylls of Theocritus, was adopted by Virgil, and was revived  in the Renaissance by Dante, Petrarch, and Boccaccio. Edmund Spenser�s  Shepheardes Calender, a series of 12 eclogues, was the first outstanding  pastoral poem in English. Eighteenth-century English poets used the  eclogue for ironic verse on nonpastoral subjects. Since then a distinction  has been made between eclogue and pastoral, with eclogue referring only  to the dialogue or soliloquy form.</p><p>Eco Va-ko,\ English Ve-ko\, Umberto (b.

It has traditionally provided instruction in drawing, paint�  ing, sculpture, engraving, and (until 1968) architecture. The Beaux-Arts  style in architecture has been particularly influential.</p><p>ecology Study of the relationships between organisms and their envi�  ronment. Physiological ecology focuses on the relationships between indi�  vidual organisms and the physical and chemical features of their  environment. Behavioral ecologists study the behaviours of individual  organisms as they react to their environment. Population ecology, includ�  ing population genetics, is the study of processes that affect the distribu�  tion and abundance of animal and plant populations. Community ecology  studies how communities of plant and animal populations function and  are organized. Paleoecology is the study of the ecology of fossil organ�  isms. Ecologists frequently concentrate on particular taxonomic groups  or on specific environments. Applied ecology applies ecological principles  to the management of populations of crops and animals. Theoretical  ecologists provide simulations of particular practical problems and  develop models of general ecological relevance.</p><p>econometrics Statistical and mathematical analysis of economic rela�  tionships. Econometrics creates equations to describe phenomena such as  the relationship between changes in price and demand. Econometricians  estimate production functions and cost functions for firms, supply-and-  demand functions for industries, income distribution in an economy, mac�  roeconomic models and models of the monetary sector for policy makers,  and business cycles and growth for forecasting. Information derived from  these models helps both private businesses and governments make deci�  sions and set monetary and fiscal policy.

Theories of economic development�the evolution of poor countries  dependent on agriculture or resource extraction into prosperous countries  with diversified economies�are of critical importance to Third World  nations. Economic development projects have typically involved large  capital investments in infrastructure (roads, irrigation networks, etc.),  industry, education, and financial institutions. More recently, the realiza�  tion that creating capital-intensive industrial sectors provides only limited  employment and can disrupt the rest of the economy has led to smaller-  scale economic development programs that aim to utilize the specific  resources and natural advantages of developing countries and to avoid  disruption of their social and economic structures. See also economic  GROWTH.</p><p>economic forecasting Prediction of future economic activity and  developments. Economic forecasts, which range from a few weeks to  many years, are widely used in business and government to help formu�  late policy and strategy. Macroeconomic forecasts predict the course of  the aggregate economy and concentrate on variables such as interest rates,  the rate of inflation, and the rate of unemployment. Forecasts of private  consumption and investment, government expenditures, and net exports  help government policymakers responsible for fiscal policy. For example,  part of the justification for a change in taxes is a forecast of its economic  effects. Microeconomic forecasts are designed to project the effects of  change at the level of an industry or a firm. Most microeconomic fore�  casts begin with assumptions about the aggregate economy before focus�  ing on the projected effects in the specific sector that is of interest.  Manufacturers and retailers use such forecasts to formulate business plans  such as those involving inventory, production levels, or hiring.</p><p>economic geology Scientific discipline concerned with the distribu�  tion of mineral deposits, the economic considerations involved in their  recovery, and assessment of the reserves available. Economic geology  deals with metal ores, fossil fuels, and other materials of commercial value,  such as salt, gypsum, and building stone. It applies the principles and  methods of various other fields, especially geophysics, structural geology,</p><p>and STRATIGRAPHY.</p><p>economic growth Process by which a nation�s wealth increases over  time. The most widely used measure of economic growth is the real rate  of growth in a country�s total output of goods and services (gauged by  the gross domestic product adjusted for inflation, or �real GDP�). Other  measures (e.g., national income per capita, consumption per capita) are  also used. The rate of economic growth is influenced by natural resources,  human resources, capital resources, and technological development in the  economy along with institutional structure and stability. Other factors  include the level of world economic activity and the terms of trade. See  also ECONOMIC DEVELOPMENT.</p><p>economic indicator Statistic used to determine the state of general  economic activity or to predict it in the future. A leading indicator is one  that tends to turn up or down before the general economy does (e.g.,  building permits, common stock prices, and business inventories). Coin�  cident indicators move in line with the economy; lagging indicators  change direction after the economy does.</p><p>economic planning Use of government to make economic decisions  with respect to the use of resources. In communist countries with a state  planning apparatus, detailed and rigid planning results in a command  economy; land, capital, and the means of production are publicly owned  and centrally allocated, and the government makes both micro- and mac�  roeconomic decisions. Microeconomic decisions include what goods and  services to produce, the quantities to produce, the prices to charge, and  the wages to pay. Macroeconomic decisions include the rate of invest�  ment and the extent of foreign trade. In most industrialized countries,  governments influence their economies indirectly through monetary and  fiscal policies. A few key economic sectors may be publicly owned, but  the trend has been toward the privatization of industries that were social�  ized in the aftermath of the Great Depression and World War II. Japan is  the most notable example of economic planning in a capitalist framework;  government and industry cooperate closely in planning patterns of capi�</p><p>tal investment, research and development, and export strategies. See also  CAPITALISM, COMMUNISM, SOCIALISM, ZAIBATSU.</p><p>economic stabilizer Any of the institutions and practices in an  economy that serve to reduce fluctuations in the business cycle through off�  setting effects on the amounts of income available for spending (dispos�  able income). The progressive income tax, unemployment compensation,  and farm price supports all help stabilize the amount of disposable  income, as do family and corporate saving.</p><p>economic system Set of principles and techniques by which a soci�  ety decides and organizes the ownership and allocation of economic  resources. At one extreme, usually called a free-enterprise system, all  resources are privately owned. This system, following Adam Smith, is  based on the belief that the common good is maximized when all mem�  bers of society are allowed to pursue their rational self-interest. At the  other extreme, usually called a pure-communist system, all resources are  publicly owned. This system, following Karl Marx and Vladimir Ilich Lenin,  is based on the belief that public ownership of the means of production  and government control of every aspect of the economy are necessary to  minimize inequalities of wealth and achieve other agreed-upon social  objectives. No nation exemplifies either extreme. As one moves from  capitalism through socialism to communism, a greater share of a nation�s pro�  ductive resources is publicly owned and a greater reliance is placed on  economic planning. Fascism, more a political than an economic system, is  a hybrid; privately owned resources are combined into syndicates and  placed at the disposal of a centrally planned state.</p><p>economic warfare Use of economic measures by governments  engaged in international conflict. These may include export and import  controls, shipping controls, trade agreements with neutral nations, and so  on. Economic warfare among belligerents began with the blockade and  interception of contraband. In World War II it was broadened to include  economic pressure applied to neutral countries from which the enemy  obtained its supplies. In the Cold War it often involved using measures  such as an embargo to deny potential enemies goods that might contrib�  ute to their war-making ability.</p><p>economics Social science that analyzes and describes the consequences  of choices made concerning scarce productive resources. Economics is the  study of how individuals and societies choose to employ those resources:  what goods and services will be produced, how they will be produced, and  how they will be distributed among the members of society. Economics is  customarily divided into microeconomics and macroeconomics. Of major  concern to macroeconomists are the rate of economic growth, the inflation  rate, and the rate of unemployment. Specialized areas of economic investi�  gation attempt to answer questions on a variety of economic activity; they  include agricultural economics, economic development, economic history,  environmental economics, industrial organization, international trade,  labour economics, money supply and banking, public finance, urban econom�  ics, and welfare economics. Specialists in mathematical economics and  econometrics provide tools used by all economists. The areas of investiga�  tion in economics overlap with many other disciplines, notably history,  MATHEMATICS, POLITICAL SCIENCE, and SOCIOLOGY.</p><p>Economist, The Weekly magazine of news and opinion, founded in  1843 and published in London, generally regarded as one of the world�s  preeminent journals of its kind. It gives thorough and wide-ranging cov�  erage of general news and particularly of international political develop�  ments that bear on the world�s economy. In accord with the views  promoted by its founders and conveyed by legendary Economist editor  Walter Bagehot, the publication maintains the position that free markets  typically provide the best method of running economies and governments.

An ecosystem�s abiotic (nonbiological) constituents include min�  erals, climate, soil, water, sunlight, and all other nonliving elements; its  biotic constituents consist of all its living members. Two major forces link  these constituents: the flow of energy and the cycling of nutrients. The  fundamental source of energy in almost all ecosystems is radiant energy  from the sun; energy and organic matter are passed along an ecosystem�s  food chain. The study of ecosystems became increasingly sophisticated in  the later 20th century; it is now instrumental in assessing and controlling  the environmental effects of agricultural development and industrializa�  tion.

The term has also been  applied to crimes committed against companies or government agencies  in order to prevent or interfere with activities allegedly harmful to the  environment. Ecoterrorism includes threats to contaminate water supplies  or to destroy or disable energy utilities, for example, and practices such  as the deployment of anthrax. Another form of ecoterrorism, often referred  to as environmental warfare, consists of the deliberate and illegal destruc�  tion, exploitation, or modification of the environment as a strategy of war  or in times of armed conflict. Examples include the U.S. military�s use  of the defoliant Agent Orange during the Vietnam War and the destruc�  tion of Kuwaiti oil wells by retreating Iraqi military forces during the 1991  Persian Gulf War. The activities of some environmental activists also have  been described as ecoterrorism. These activities include criminal trespass  on the property of logging companies and other firms and obstruction of  their operations through sabotage as well as the environmentally harm�  less modification of natural resources in order to make them unsuitable  for commercial use (a practice known as �monkeywrenching�).</p><p>Ecstasy Euphoria-inducing stimulant and hallucinogen. It is a derivative  of the amphetamine family and a relative of the stimulant methamphetamine.  Taken in pill form, it has a chemical relationship to the psychedelic drug  mescaline. Developed in 1913 as an appetite suppressant, the drug was not  originally approved for release. In the 1950s and �60s, it began to be used  in psychotherapy. The drug increases the production of the neurotransmit�  ter serotonin and blocks its reabsorption in the brain; it also increases the  amount of the neurotransmitter dopamine. Stimulation of the central ner�  vous system gives users feelings of increased energy and lowers social  inhibitions. By the 1980s, parties and dances that featured Ecstasy use  (known as �raves�) became popular. Despite its ban in the U.S. and the rest  of the world, the drug retained a huge following, and it played an important  role in the youth subculture, similar to that of LSD during the 1960s.</p><p>ectopic pregnancy \ek-'ta-pik\ or extrauterine pregnancy</p><p>Condition in which a fertilized egg is imbedded outside the uterus (see  fertilization). Early on, it may resemble a normal pregnancy, with hormonal  changes, amenorrhea, and development of a placenta. Later, most patients  have pain as the growing embryo stretches the structure it is attached to.  Rupture may cause life-threatening bleeding. A tubal pregnancy may  result from obstruction of the egg�s passage through the fallopian tube.  In an ovarian pregnancy, the egg is fertilized before it leaves the ovary.  Implantation elsewhere in the abdomen is an abdominal pregnancy.</p><p>ectotherm Vek-ta-.thamA Any so-called cold-blooded animal; that is,  any animal whose regulation of body temperature depends on external  sources, such as sunlight or a heated rock surface. The ectotherms include  the FiSHes, amphibians, reptiles, and invertebrates. The body temperatures of  aquatic ectotherms are usually very close to those of the water. Ectotherms  do not require as much food as warm-blooded animals (endotherms) of the  same size, but most cannot deal as well with cold surroundings.</p><p>Ecuador officially Republic of Ecuador Country, northwestern  South America. Area: 105,037 sq mi (272,045 sq km), including the  Galapagos Islands. Population (2005 est.): 13,364,000. Capital: Quito.  About two-fifths of the population are Indian (mostly Quechua), and two-  fifths are mestizos; most of the rest are of Spanish ancestry. Language:  Spanish (official). Religion: Christianity (predominantly Roman Catholic;  also Protestant). Currency: U.S. dollar. Pacific coastal lowlands rise to the  peaks and highlands of the Andes Mountains, which give way to the Ecua�  doran portion of the tropical Amazon River basin in the east. The Andes rise  dramatically in two chains that run north to south and are separated by  high valleys. The highest peak is Chimborazo, which rises to an elevation  of 20,702 ft (6,310 m); nearby Cotopaxi, 19,347 ft (5,897 m) high, is the  world�s highest active volcano. The country lies in an active earthquake  zone and is prone to violent seismic activity. Almost two-fifths of the land  is forested, with tropical rainforests in the east. Ecuador straddles the  Equator. Its climate varies from tropical in the lowlands to temperate in the  highlands. It has a developing economy based primarily on mining, manu�  facturing, services, and agriculture. Principal exports include crude petro�  leum, bananas, and shellfish. It is a republic with one legislative house; its  head of state and government is the president. What is now Ecuador was  conquered by the Incas in the second half of the 15th century and came  under Spanish control in 1534. Under the Spaniards it was a part of the  Viceroyalty of Peru until 1740, when it became a part of the Viceroyalty of  New Granada. It gained its independence from Spain in 1 822 as part of the</p><p>republic of Gran Colombia and in 1830  became a sovereign state. A succession of  authoritarian governments ruled into the  mid-20th century, and the military played a  prominent role in politics. Border disputes</p><p>led to war with Peru in 1941; conflicts with that country continued peri�  odically until a final demarcation of the border in 1998. The economy  thrived during the 1970s because of large profits from petroleum exports  but was depressed in the 1980s because of lower oil prices. In the 1990s  social unrest caused political instability and several changes in the presi�  dency. In a controversial move to help stabilize the economy, the U.S. dol�  lar replaced the sucre as the national currency in 2000.</p><p>ecumenism Xe-'kyu-mo-.ni-zam, , e-kyu-mo- 1 ni-z3m\ Movement toward  unity or cooperation among the Christian churches. The first major step  in the direction of ecumenism was the International Missionary Confer�  ence of 1910, a gathering of Protestants. Several Protestant denomina�  tions inaugurated a Life and Work Conference (on social and practical  problems) in 1925 and a Faith and Order Conference (on church doctrine  and governance) in 1927. After World War II the World Council of  Churches (WCC) was established; the International Missionary Confer�  ence joined it in 1961. The Roman Catholic church also has shown strong  interest in improving interchurch relations since the Second Vatican Coun�  cil (1962�65) and, with the patriarch of Constantinople, has lifted the  excommunication of 1054. The Eastern Orthodox church was active in  the movement since 1920 and joined the WCC at its inception. The more  conservative or fundamentalist Protestant denominations have generally  refrained from involvement. Another important factor in 20th-century  ecumenism was the creation of united churches that reconcile splintered  sects, such as the United Church of Christ (1957) and the Evangelical  Lutheran Church in America (1988).</p><p>eczema See dermatitis</p><p>Edda Body of ancient Icelandic literature.

A daughter of Con-  gregationalist descendants of old  New England families, she married  in 1843; her husband died the fol�  lowing year, and she married again  in 1853. She suffered from ill health  for much of her life. In the early  1860s she was cured of a spinal  malady by Phineas P. Quimby  (1802-66), who cured ailments with�  out medication. She remained well  until shortly after Quimby�s death; in  1866 she suffered a severe fall and  lost hope for recovery, only to be  healed by reading the New Testa�  ment. She considered that moment  her discovery of Christian Science  and spent several years evolving her  system. In 1875 she published Sci�  ence and Health with Key to the  Scriptures , which her followers  regarded as divinely inspired. Hav�  ing divorced in 1873, in 1877 she married one of her followers, Asa G.  Eddy (d. 1882). The Church of Christ, Scientist was organized in 1879.

The city and most of the council area, including the  busy port of Leith on the Firth of Forth, lie within the historic county of  Midlothian. Located in southeastern Scotland, the original burgh, now  known as the Old Town, arose in the 11th century, around Edinburgh  Castle, the royal residence of Malcolm III MacDuncan. In 1329 Robert  the Bruce granted Edinburgh a town charter; it became the capital of the  Scottish kingdom in 1437. The city was destroyed in 1544 in the border  wars with England; its characteristic use of stone architecture began with  this rebuilding. During the 18th century Scotland experienced a cultural  and intellectual renaissance, and Edinburgh was home to such luminaries  as David Hume, Adam Smith, Robert Burns, and Walter Scon. It was the  birthplace of Encyclopaedia Britannica (1768) and the Edinburgh Review  (1802). The city expanded in the late 18th century with the development  of the Georgian-style New Town, separated from the Old Town by a val�  ley. Edinburgh is the centre of Scottish culture and education and is home  to the University of Edinburgh, the National Library, the National Gallery,  and the Royal Scottish Museum. It is the site of the Scottish Parliament,  which first convened in 1999.</p><p>Edinburgh, University of Private university in Edinburgh, Scotland.

It strengthened Russia�s position in Eastern Europe  and weakened that of the Ottoman empire, and it foreshadowed the Otto�  man empire�s dependence on the European balance of power and the dis�  memberment of its Balkan possessions.</p><p>Edison, Thomas Alva (b. Feb. 11, 1847, Milan, Ohio, U.S.�d. Oct.  18, 1931, West Orange, N.J.) U.S. inventor. He had very little formal  schooling. He set up a laboratory in his father�s basement at age 10; at  12 he was earning money selling newspapers and candy on trains. He  worked as a telegrapher (1862-68) before deciding to pursue invention  and entrepreneurship. Throughout much of his career, he was strongly  motivated by efforts to overcome his handicap of partial deafness. For  Western Union he developed a machine capable of sending four telegraph  messages down one wire, only to sell the invention to Western Union�s</p><p>rival, Jay Gould, for more than $100,000. He created the world�s first  industrial-research laboratory, in Menlo Park, N.J. There he invented the  carbon-button transmitter (1877), still used in telephone speakers and  microphones today; the phonograph (1877); and the incandescent light-  bulb (1879). To develop the lightbulb, he was advanced $30,000 by such  financiers as J.P. Morgan and the Vanderbilts. In 1882 he supervised the  installation of the world�s first permanent commercial central power sys�  tem, in lower Manhattan. After the death of his first wife (1884), he built  a new laboratory in West Orange, N.J. Its first major endeavour was the  commercialization of the phonograph, which Alexander Graham Bell had  improved on since Edison�s initial invention. At the new laboratory Edi�  son and his team also developed an early movie camera and an instru�  ment for viewing moving pictures; they also developed the alkaline  storage battery. Although his later projects were not as successful as his  earlier ones, Edison continued to work even in his 80s. Singly or jointly,  he held a world-record 1,093 patents, nearly 400 of them for electric light  and power. He always invented for necessity, with the object of devising  something new that he could manufacture. More than any other, he laid  the basis for the technological revolution of the modem electric world.</p><p>Edmonton City (pop., 2001: city, 666,104; metro, area, 937,845), capi�  tal of Alberta, Canada. Located on the North Saskatchewan River, in the  centre of the province, it began as a series of fur-trading posts built from  1795. With the arrival of the railway and an influx of settlers in the late  19th century, Edmonton began to prosper economically, and in 1905 it  became the capital of the new province of Alberta. The 1947 discovery  of petroleum in the area greatly stimulated the city�s growth; an agricul�  tural and oil-based economy still prevails. It is the distribution centre of  northwestern Canada.

He was a Republican member (1854-59) and  speaker (1856-59) of the Vermont House of Representatives and a mem�  ber and president pro tern (1861-62) of the Vermont Senate. He was  appointed to the U.S. Senate in 1866 and served until 1891; he was chair�  man of the Senate Judiciary Committee (1872-79; 1882-91) and presi�  dent pro tern of the Senate (1883-85). Edmunds was active in the  impeachment (1868) of President Andrew Johnson and was a founding  member of the commission that decided the election of 1876.

Tokugawa Ieyasu, the  first Tokugawa shogun, chose Edo (present-day Tokyo) as Japan�s new  capital, and it became one of the largest cities of its time and was the site  of a thriving urban culture. In literature, Basho developed poetic forms  later called haiku, and Ihara Saikaku composed virtuoso comic linked-verse  and humorous novels; in theatre, both kabuki (with live actors) and bun-  raku (with puppets) entertained townspeople (samurai, for whom theatre�  going was forbidden, often attended in disguise). The development of  polychrome woodblock printing techniques made it possible for ordinary  people to obtain prints of popular kabuki actors or trendsetting courtesans  (see ukiyo-e). Travelogues extolled the scenic beauty or historic interest of  spots in distant provinces, and temple or shrine pilgrimages to distant  places were popular. In scholarship, Kokugaku (�National Learning�)  called attention to Japan�s most ancient poetry and oldest written histo�  ries. The study of Europe and its sciences, called rangaku, or �Dutch  learning,� became popular despite extremely limited contact with Europe.  Neo-Confucianism was also popular.

In developing cultures  there is often little formal education; children learn from their environ�  ment and activities, and the adults around them act as teachers. In more  complex societies, where there is more knowledge to be passed on, a more  selective and efficient means of transmission�the school and teacher�  becomes necessary. The content of formal education, its duration, and who  receives it have varied widely from culture to culture and age to age, as  has the philosophy of education. Some philosophers (e.g., John Locke)  have seen individuals as blank slates onto which knowledge can be writ�  ten. Others (e.g., Jean-Jacques Rousseau) have seen the innate human state  as desirable in itself and therefore to be tampered with as little as pos�  sible, a view often taken in alternative education.

July 7, 1309, Burgh by Sands, near Carl�  isle, Cumberland) King of England (1272-1307). The eldest son of Henry  III, he supported his father in a civil war with the barons, but his violent  temper contributed to Henry�s defeat at the Battle of Lewes (1264).  Edward triumphed over the rebels in the following year when he defeated  them and slew their leader at Evesham. Edward joined the abortive Cru�  sade of Louis IX of France (the Eighth Crusade) in 1271-72, then returned  to England to succeed his father. His reign was a time of rising national  consciousness, in which he strengthened the crown against the nobility.  He fostered the development of Parliament and played an important role  in defining English common law. He conquered Wales (1277) and crushed  Welsh uprisings against English rule, but his conquest of Scotland (1296),  including the defeat of William Wallace, was undone by later revolts. He  expelled the Jews from England in 1290; they would not be readmitted  until 1655. He died on a campaign against Robert I, who had proclaimed  himself king of Scotland the previous year.</p><p>Edward II known as Edward of Caernarfon \kar-'na-von\ (b. April  25, 1284, Caernarfon, Caernarfonshire, Wales�d. September 1327, Ber�  keley, Gloucestershire, Eng.) King of England (1307-27). He was the son  of Edward I. He angered the barons by granting the earldom of Cornwall  to his favourite, Piers Gaveston; the barons then drew up the Ordinances  (1311), a document limiting the king�s power over finances and appoint�  ments, and executed the arrogant Gaveston (1312). The English defeat by  Robert I at the Battle of Bannockburn (1314) ensured Scottish indepen�  dence and left Edward at the mercy of powerful barons, notably Thomas  of Lancaster. Edward defeated and executed Lancaster in 1322, freeing  himself from baronial control and revoking the Ordinances. His queen,  Isabella, helped her lover, Roger de Mortimer, invade England with other  dissatisfied nobles and depose Edward in favour of his son, Edward III.  Edward II was imprisoned and probably murdered.</p><p>Edward III known as Edward of Windsor (b. Nov. 13,1312, Wind�  sor, Berkshire, Eng.�d. June 21, 1377, Sheen, Surrey) King of England  (1327-77). His mother, Isabella of France, deposed his father, Edward II,  and crowned the 15-year-old Edward in his place. Isabella and her lover,  Roger de Mortimer, governed in Edward�s name for four years and per�  suaded him to grant the Scots their independence (1328). After having  Mortimer executed in 1330, Edward became the sole ruler of England.  By asserting his right to the French crown, he began the Hundred Years'  War. He instituted the Order of the Garter in 1342. He defeated the French  at the Battle of Crecy (1346) and captured Calais (1347), though lack of  funds forced him to sign a truce. The Black Death hit England in 1348,  but fighting continued. The Scots surrendered to Edward in 1356, and the  same year his son Edward the Black Prince won a major victory for the  English at the Battle of Poitiers. In 1360 Edward gave up his claim to the  French crown in return for Aquitaine. The war later resumed when Charles  V repudiated the Treaty of Calais; Edward lost Aquitaine, and he signed  a new truce in 1375. In his later years he fell under the influence of his  greedy mistress, Alice Perrers, and his son John of Gaunt.</p><p>Edward IV (b. April 28, 1442, Rouen, France�d. April 9, 1483, West�  minster, Eng.) King of England  (1461-70, 1471-83). His father, a  claimant to the throne, was killed in  1461, and Edward was crowned,  thanks largely to his cousin the earl  of Warwick. This alliance did not  last, and, after much intrigue and  fighting, Edward was deposed and  fled in 1470. The next year he  returned to become a leading partici�  pant in the Wars of the Roses, defeat�  ing and killing Warwick and nearly  all the remaining Lancastrian lead�  ers. After murdering Henry VI and  repelling an attack on London,</p><p>Edward remained secure as king for  the rest of his life. He invaded  France, which Henry had inherited  but largely lost; though the attempt  was unsuccessful, Edward made an  excellent financial settlement by  treaty. His administrative achieve�  ments made his reign a time of pros�  perity and success. Seven children survived him; his two sons were  probably murdered in the Tower of London, and his eldest daughter mar�  ried Henry VII.</p><p>Edward VI (b. Oct. 12, 1537, London, Eng.�d.

During the  young king�s reign, power was wielded first by his uncle the duke of  Somerset (1547-49) and then by the duke of Northumberland. Facing death  from tuberculosis, Edward was persuaded to exclude his two half sisters  (later queens) Mary I and Elizabeth I  from the succession and to put  Northumberland�s daughter-in-law,</p><p>Lady Jane Grey, in line for the throne.</p><p>Edward VII orig.

June 23, 1894, Richmond, Surrey, Eng.�d. May 28,  1972, Paris, France) King of the  United Kingdom (1936) who abdi�  cated voluntarily. Son of George V,  he served as a staff officer in World  War I. After the war he made exten�  sive goodwill tours of the British  Empire and became very popular  with the British people. In 1930 he  became friends with Wallis Simpson  and her husband and by 1934 had  fallen in love with her. In January  1936 he succeeded to the throne on  his father�s death. Unable to gain  social and political acceptance for  his proposed marriage to Simpson,  he abdicated in December, becoming  the only British sovereign to resign  the crown voluntarily. He was cre�  ated duke of Windsor and in 1937  married Simpson, who became the  duchess of Windsor. At Winston  Churchill�s invitation, he served as  governor of the Bahamas during  World War II, and after 1945 the couple lived in Paris. Though they were  counted among the social elite, not until 1967 were they invited to attend  an official public ceremony with other members of the royal family.</p><p>Edward the Black Prince (b. June 15, 1330, Woodstock, Oxford�  shire, Eng.�d. June 8, 1376, Westminster, near London) Prince of Wales  (1343-76). Son of Edward III, he apparently received his sobriquet because  he wore black armour. He was one of the outstanding commanders of the  Hundred Years' War, winning a major victory at the Battle of Poitiers in  1356. He was prince of Aquitaine 1362-72; his rule there was a failure,  for which he was largely to blame. He returned sick and broken to England  and formally surrendered his principality to his father. He had no succes�  sor as prince of Aquitaine. Though the heir apparent, he never became  king; his son became Richard II.</p><p>Edward the Confessor, Saint (b. c. 1003, Islip, Eng.�d. Jan. 5,  1066, London; canonized 1161; feast day originally January 5, now Octo�  ber 13) King of England (1042-66). The son of Ethelred II, he was exiled  to Normandy for 25 years (1016-41) while the Danes held England (see  Canute the Great). For the first 11 years of his reign, the real master of  England was Godwine, earl of Wessex. Edward outlawed Godwine in  1051 and appointed Normans to high positions in government, thus pre�  paring the way for the Norman Conquest. Godwine continued his oppo�  sition, and his son Harold (see Harold II) dominated England after 1053,  subjugating Wales in 1063. Edward named Harold as his successor on his  deathbed, but the duke of Normandy (the future William I) invaded  England to claim the crown earlier promised him. Though an ineffectual  monarch, Edward was famous for his piety, which earned him the epithet  �the Confessor.�</p><p>Edwards, Blake orig. William Blake McEdwards (b.

In</p><p>1727 he was named a pastor at his grandfather�s church in Northampton,  Mass. His sermons on �Justification by Faith Alone� gave rise to a revival  in the Connecticut River valley in 1734, and in the 1740s he was also  influential in the Great Awakening. In 1750 he was dismissed from the  Northampton church over a disagreement on who was eligible to take  communion, and he became pastor in Stockbridge in 1751. He died of  smallpox shortly after accepting the presidency of the College of New  Jersey (now Princeton University). A staunch Calvinist, he emphasized  original sin, predestination, and the need for conversion. His most famous  sermon, �Sinners in the Hands of an Angry God,� vividly evokes the fate  of unrepentant sinners in hell.</p><p>Edwards, Robert See Patrick Steptoe and Robert Edwards</p><p>eel Any of more than 500 fish species (order Anguilliformes) that are  slender, elongated, and usually scaleless, with long dorsal and anal fins  that are continuous around the tail tip.

It is stated as the ratio  of a system�s work output to its work input. The efficiency of a real sys�  tem is always less than 1 because of friction between moving parts. A  machine with an efficiency of 0.8 returns 80% of the work input as work  output; the remaining 20% is used to overcome friction. In a theoretically  frictionless, or ideal, machine, the work input and work output are equal,  and the efficiency would be 1, or 100%.</p><p>effigy mound Earthen mound in the form of a bird or animal (e.g,  bear, deer, turtle, buffalo), found in the northern central U.S., especially  the Ohio River valley.

The mounds were built over  the course of the Woodland period (1000 bc-ad 1200), with the effigy  mounds probably constructed between ad 400 and 1200.

In zoology, the Latin term  ovum is often used to refer to the single cell, whereas the word egg may be  applied to the entire specialized structure or capsule that consists of the  ovum, its various protective membranes, and any accompanying nutritive  materials. The egg or ovum, like the male gamete (sperm), bears only a  single (haploid; see ploidy) set of chromosomes. When female and male  gametes unite during fertilization, the double (diploid) set of chromosomes  is restored in the resulting zygote. In humans, the ovum matures inside one  of the ovary�s follicles (hollow group of cells) and is released when the  follicle ruptures (ovulation).

In animals, the  amount of nutritive material (yolk) deposited in an egg is dependent on the  length of time before the developing animal can feed itself or, in the case  of mammals, begins to receive nourishment from the maternal circulation.  Most animal eggs are enclosed by one or more membranes. Insect eggs are  covered by a thick, hard outer membrane, and amphibian eggs are sur�  rounded by a jellylike layer. The term egg also refers to the content of the  hard-shelled reproductive body produced by a bird or reptile.</p><p>Eggleston, Edward (b. Dec. 10, 1837, Vevay, Ind., U.S.�d.

According to Sigmund Freud, it coexists with  the id (the unconscious, instinctual portion of the psyche) and the super�  ego (the portion representing the conscience, or the internalization of</p><p>societal norms). The ego is not coextensive with either the personality or  the body; rather, it serves to integrate these and other aspects of the per�  son, such as memory, imagination, and behaviour. It mediates between the  id and the superego by building up various defense mechanisms.</p><p>egoism In ethics, the principle that we should each act so as to promote  our own interests. The great advantage of such a position is that it avoids  any possible conflict between morality and self-interest; if it is rational  for us to pursue our own interest, the rationality of morality is equally  clear. The prescriptive thesis of ethical egoism can be distinguished from  the descriptive thesis of psychological egoism. Psychological egoism is a  generalization about human motivation, namely, that everyone always acts  so as to promote his or her own interests.</p><p>egret Ve-gret\ Any of several species (mainly in the genus Egretta) of  wading birds in the same family  (Ardeidae) as herons and bitterns.</p><p>Egrets live in marshes, lakes, humid  forests, and other wetland environ�  ments worldwide.

Area: 385,229  sq mi (997,739 sq km). Population  (2005 est.): 70,457,000. Capital: Cairo. The people are largely Egyptian  Arabs. Language: Arabic (official). Religions: Islam (official; predomi�  nantly Sunni); also Christianity. Currency: Egyptian pound. Egypt occu�  pies a crossroads between Africa, Europe, and Asia. The majority of its  land is in the arid western and eastern deserts, separated by the country�s  dominant feature, the Nile River. The Nile forms a flat-bottomed valley,  generally 5-10 mi (8-16 km) wide, that fans out into the densely popu�  lated delta lowlands north of Cairo. The Nile valley (in Upper Egypt) and  delta (Lower Egypt), along with scattered oases, support all of Egypt�s  agriculture and have virtually all of its population. Egypt has a develop�  ing, mainly socialist, partly free-enterprise economy based primarily on  industry, including petroleum production, and agriculture. It is a republic  with one legislative house; its chief of state is the president, and the head  of government is the prime minister. It is one of the world�s oldest con�  tinuous civilizations. Upper and Lower Egypt were united c. 3000 bc,  beginning a period of cultural achievement and a line of native rulers that  lasted nearly 3,000 years. Egypt�s ancient history is divided into the Old,  Middle, and New Kingdoms, spanning 31 dynasties and lasting to 332 bc.  The pyramids date from the Old Kingdom, the cult of Osiris and the refine�  ment of sculpture from the Middle Kingdom, and the era of empire and  the Exodus of the Jews from the New Kingdom. An Assyrian invasion  occurred in the 671 bc, and the Persian Achaemenids established a dynasty  in 525 bc. The invasion by Alexander the Great in 332 bc inaugurated the  Macedonian Ptolemaic period and the ascendancy of Alexandria as a cen�  tre of learning and Hellenistic culture. The Romans held Egypt from 30  bc to ad 395; later it was part of the Byzantine Empire. After the Roman  emperor Constantine granted tolerance to the Christians in 313, a formal  Egyptian (Coptic) church emerged. Egypt came under Arab control in 642  and ultimately was transformed into an Arabic-speaking state, with Islam  as the dominant religion. Held by the Umayyad and 'Abbasid dynasties, in  969 it became the centre of the Fajimid dynasty. In 1250 the MamlOk dynasty  established a state that lasted until 1517, when Egypt fell to the Ottoman  Empire. An economic and cultural decline ensued. Egypt became a Brit�  ish protectorate in 1914 and received nominal independence in 1922,  when a constitutional monarchy was established. A group of army offic-</p><p>(b.

A union with Syria  to form the United Arab Republic (1958�  61) failed. Following three wars with  Israel (see Arab-Israeli wars), Egypt, under  Nasser�s successor, Anwar el-Sadat, made peace with the Jewish state,  thus alienating many fellow Arab countries. Sadat was assassinated by  Islamic extremists in 1981 and was succeeded by HosnT Mubarak, who  continued to negotiate peace. Although Egypt took part in the coalition  against Iraq during the First Persian Gulf War (1991), it later began peace  overtures with countries in the region.</p><p>Egyptian architecture Houses, palaces, temples, tombs, and other  buildings of ancient Egypt. Most Egyptian towns were situated on the  floodplain of the Nile and have been lost, but religious structures built on  higher ground have survived in many forms. Tomb architecture was often  grandiose. The tomb was not simply a place to lay a corpse, but the home  of the deceased, provided with goods to ensure continued existence after  death. Wood and bricks made of mud were the standard domestic build�  ing materials, but, from the Old Kingdom (c. 2575-c. 2130 bc) on, stone  was used for tombs and temples. Egyptian masons used stone to repro�  duce the forms of wood and brick buildings. Mastabas and step pyramids  were used for tomb superstructures, but the most characteristic form of  the Old Kingdom was the true pyramid. The finest example is the monu�  mental Great Pyramid of Khufu (Cheops) at Giza. Simple chapel rooms  with stelae (see stele) for burying commoners were located some distance  from the royal burial compounds. In the New Kingdom (1539-1075 bc),  royal tombs were cut into the face of cliff's to discourage looting; elabo�  rate complexes of tombs and mortuary temples were built in the Valley of  the Kings at Thebes. Two principal types of temple can be distinguished:  cult temples for worship of the gods and funerary, or mortuary, temples.  Most notable were the great stone cult temples; imposing remains can be  seen at Luxor, Karnak, Abydos, and Abu Simbel.</p><p>Egyptian art Ancient sculptures, paintings, and decorative crafts pro�  duced in the dynastic periods of the 3rd-1st millennia bc in the Nile Val�  ley of Egypt and Nubia. Egyptian art served those in power as a forceful  propaganda instrument that perpetuated the existing framework of soci�  ety. Much of what has survived is associated with ancient tombs. The  course of art in Egypt paralleled the country�s political history and is  divided into three periods: Old Kingdom (c. 2700-c. 2150 bc), Middle  Kingdom (c. 2000-c. 1670 bc), and New Kingdom (c. 1550-c. 1070 bc).  The Old Kingdom�s stone tombs and temples were decorated with vig�  orous and brightly painted reliefs illustrating the daily life of the people.  Rules for portraying the human figure were established, specifying pro�  portions, postures, and placement of details, often linked to the subjects�</p><p>social standing. An artistic decline at the end of the Old Kingdom led to  a revival in the more stable political climate of the Middle Kingdom,  notable for its expressive portrait sculptures of kings and its excellent  relief sculptures and painting. The New Kingdom brought a magnificent  flowering of the arts; great granite statues and wall reliefs glorified rulers  and gods, painting became an independent art, and the decorative crafts  reached new peaks, the treasure of Tutankhamen�s tomb typifying the vari�  ety of luxury items created. See also Egyptian architecture.</p><p>Egyptian language Extinct Afro-Asiatic language of the Nile River  valley. Its very long history comprises five periods: Old Egyptian (c.  3000-c. 2200 bc), best exemplified by a corpus of religious inscriptions  known as the Pyramid Texts and a group of autobiographical tomb inscrip�  tions; Middle Egyptian (c. 2200-c. 1600 bc), the classical literary lan�  guage; Late Egyptian (1300-700 bc), known mainly from manuscripts;  Demotic (c. 700 bc-c. ad 400), used in the periods of Persian, Greek, and  Roman dominance and differing from Late Egyptian chiefly in its graphic  system; and Coptic (c. ad 300-at least the 17th century), the language of  Christian Egypt, gradually supplanted as a vernacular by Arabic from the  9th century on but still preserved to some degree in the liturgy of the Cop�  tic Orthodox Church. Egyptian was originally written in hieroglyphs, out  of which evolved hieratic, a cursive rendering of hieroglyphs, and  demotic, a kind of shorthand reduction of hieratic. Coptic was written in  a modified form of the Greek alphabet, with seven signs added from the  demotic script for sounds that did not occur in Greek.</p><p>Egyptian law Law that prevailed in Egypt from c. 3000 bc to c. 30  bc. No formal Egyptian code of law has been preserved, but legal docu�  ments (e.g., deeds and contracts) have survived. The pharaoh was the ulti�  mate authority in the settlement of disputes. The next most powerful  individual was the vizier, who directed all administrative branches of the  government, sat in judgment on court cases, and appointed magistrates.  Parties to a dispute were not represented by legal advocates; they spoke  for themselves, presented any documentary evidence, and sometimes  called witnesses. Both men and women could own and bequeath prop�  erty, file lawsuits, and bear witness. Punishment for criminal offenders  could be severe, but in some periods basic human rights, even those of  slaves, were acknowledged. Egyptian law strongly influenced both Greek  and Roman law.</p><p>Egyptian religion Polytheistic belief system of ancient Egypt from  the 4th millennium bc to the first centuries ad, including both folk tradi�  tions and the court religion. Local deities that sprang up along the Nile  Valley had both human and animal form and were synthesized into  national deities and cults after political unification c. 2925 bc. The gods  were not all-powerful or all-knowing, but were immeasurably greater than  humans. Their characters were not neatly defined, and there was much  overlap, especially among the leading deities. One important deity was  Horus, the god-king who ruled the universe, who represented the earthly  Egyptian king. Other major divinities included Re, the sun god; Ptah and  Aton, creator gods; and Isis and Osiris. The concept of Ma�at (�order�)  was fundamental: the king maintained Ma�at both on a societal and cos�  mic level. Belief in and preoccupation with the afterlife permeated Egyp�  tian religion, as the surviving tombs and pyramids attest. Burial near the  king helped others gain passage to the netherworld, as did spells and  passwords from the Book of the Dead.</p><p>Egyptology Study of pharaonic Egypt from the putative beginnings of  Egyptian culture (c. 4500 bc) to the Arab conquest (ad 641). Egyptology  began with discovery of the Rosetta Stone (1799) and the publication of  Description de TEgypt (1809-28) by scholars accompanying Napoleon I.  In the 19th century the Egyptian government opened Egypt to Europeans,  many of whose collecting activities amounted to little more than plun�  dering. In 1880 Funders Petrie brought controlled, scientifically recorded  excavation to Egypt, revolutionizing archaeology and pushing theories on  Egyptian origins back to 4500 bc. The discovery of Tutankhamen�s tomb  in 1922 heightened public awareness. In 1975 the First International Con�  gress of Egyptology convened in Cairo. Many sites remain that have been  only slightly explored.</p><p>Ehrenberg Ver-on-.berkV Christian Gottfried (b. April 19, 1795,  Delitzsch, Saxony�d. June 27, 1876, Berlin, Ger.)

After early work on distribution of foreign substances in the body  and on cell nutrition, he found uses for staining agents in diagnosis  (including that of tuberculosis) and treatment. He also researched typhoid,  fever medications, and eye diseases. In one paper, he showed that differ�  ent tissues� oxygen consumption reflected the intensity of their cell pro�  cesses. Ehrlich developed a method of stimulating production of  antitoxins by injecting increasing amounts of toxin into animals; his work  was crucial to the creation of a diphtheria antitoxin. He and Elie Metch-  nikoff received the 1908 Nobel Prize for Physiology or Medicine.

His most influential work was The Population Bomb (1968). In  1990 he shared with Edward O. Wilson Sweden�s prestigious Crafoord  Prize.</p><p>Ehrlichman, John D(aniel) (b. March 20, 1925, Tacoma, Wash.,  U.S.�d. Feb. 14, 1999, Atlanta, Ga.) U.S. presidential assistant who  played a central role in the Watergate scandal. He received his law degree  from Stanford University in 1951 and established a law firm in Seattle,  Wash. In 1969 he became domestic affairs adviser to Pres. Richard Nixon.  With H.R. Haldeman he formed the so-called �palace guard� that con�  trolled access to the president and filtered information directed to him.  Ehrlichman soon established a group known as the �plumbers,� whose  purpose was to acquire political intelligence and to repair �leaks� of infor�  mation to the press. When members of the plumbers were caught break�  ing into Democratic Party headquarters at the Watergate complex,  Ehrlichman became involved in a cover-up of involvement by White  House officials. He was forced to resign in 1973. Convicted of conspiracy,  perjury, and obstruction of justice, he served 18 months in jail.

Born to the nobility, he and his family lost their castle in the Napo�  leonic Wars, and he later worked in the Prussian civil service. He became  associated with the national leaders of the Romantic movement while study�  ing in Berlin. His most important prose work, Memoirs of a Good-for-  Nothing (1826), is considered a high point of Romantic fiction. In the  1830s he wrote poetry that achieved the popularity of folk songs and  inspired such composers as Robert Schumann, Felix Mendelssohn, Johannes  Brahms, Hugo Wolf, and Richard Strauss.</p><p>Eichmann Vik-.manX, (Karl) Adolf (b.

March 14, 1879, Ulm, Wiirttemberg, Ger.�d.  April 18, 1955, Princeton, N.J., U.S.) German-Swiss-U.S. scientist. Born  to a Jewish family in Germany, he grew up in Munich, and his family  moved to Switzerland in 1894. He became a junior examiner at the Swiss  patent office in 1902 and began producing original theoretical work that  laid many of the foundations for 20th-century physics. He received his  doctorate from the University of Zurich in 1905, the same year he won  international fame with the publication of three articles: one on Brown�  ian motion, which he explained in terms of molecular kinetic energy; one  on the photoelectric effect, in which he demonstrated the particle nature of  light; and one on his special theory of relativity, which included his for�  mulation of the equivalence of mass and energy (E = me 2 ). Einstein held  several professorships before becoming director of Berlin�s Kaiser Wil�  helm Institute in 1914. In 1915 he published his general theory of rela�  tivity, which was confirmed experimentally during a solar eclipse in 1919  with observations of the deviation of light passing near the Sun. He  received a Nobel Prize in 1921 for his work on the photoelectric effect,  his work on relativity still being controversial. He made important con�  tributions to quantum field theory, and for decades he sought to discover  the mathematical relationship between electromagnetism and gravitation,  which he believed would be a first step toward discovering the common</p><p>laws governing the behaviour of everything in the universe, but such a  unified field theory eluded him. His theories of relativity and gravitation  represented a profound advance over Newtonian physics and revolution�  ized scientific and philosophical inquiry. He resigned his position at the  Prussian Academy when Adolf Hitler came to power and moved to Prin�  ceton, N.J., where he joined the Institute for Advanced Study. Though a  longtime pacifist, he was instrumental in persuading Pres. Franklin  Roosevelt in 1939 to initiate the Manhattan Project for the production of  an atomic bomb, a technology his own theories greatly furthered, though  he did not work on the project himself. The most eminent scientist in the  world in the postwar years, he declined an offer to become the first prime  minister of Israel and became a strong advocate for nuclear disarmament.</p><p>Einstein's mass-energy relation Relationship between mass (m)  and energy ( E) in Albert Einstein�s special theory of relativity, expressed E  = me 2 , where c equals 186,000 mi/second (300,000 km/second), the speed  of light. Whereas mass and energy were viewed as distinct in earlier  physical theories, in special relativity a body�s mass can be converted into  energy in accordance with Einstein�s formula.

In World War II Gen.</p><p>George Marshall appointed him to  the army�s war-plans division  (1941), then chose him to command  U.S. forces in Europe (1942). After  planning the invasions of North  Africa, Sicily, and Italy, he was  appointed supreme commander of  Allied forces (1943). He planned the  Normandy Campaign (1944) and the  conduct of the war in Europe until  the German surrender (1945). He  was promoted to five-star general  (1944) and was named army chief of  staff in 1945. He served as president  of Columbia University from 1948 until being appointed supreme com�  mander of NATO in 1951. Both Democrats and Republicans courted  Eisenhower as a presidential candidate; in 1952, as the Republican can�  didate, he defeated Adlai Stevenson with the largest popular vote to that  time. He defeated Stevenson again in 1956 in an even larger landslide.  His policy of support for Middle Eastern countries facing communist  aggression, enunciated in the Eisenhower Doctrine, was a continuation of  the containment policy adopted by the Harry Truman administration (see  Truman Doctrine). He sent federal troops to Little Rock, Ark., to enforce  integration of a city high school (1957). When the Soviet Union launched  Sputnik I (1957), he was criticized for failing to develop the U.S. space  program; he responded by creating NASA (1958).

After studying stage direction with  Vsevolod Meyerhold, he turned to filmmaking. In Strike (1924) he intro�  duced his influential concept of film montage, adding startling and often  discordant images to the main action to create the maximum psychologi�  cal impact. He further developed the style in The Battleship Potemkin  (1925), a commissioned propaganda film that is one of the most influen�  tial films of all time. Among his other films are October (Ten Days That  Shook the World ; 1928) and The General Line (1929). After a frustrating  period in Hollywood and Mexico (1930-33), he returned to the Soviet  Union and made two more classics, Alexander Nevsky (1938) and Ivan  the Terrible (2 parts, 1945�46).</p><p>Eisner Vlz-norV Kurt (b.

The ejido consists of cul�  tivated land, pastureland, other uncultivated lands, and th e fundo legal, or  town site. The cultivated land is generally apportioned in family holdings,  which until recently could not be sold but could be passed down to heirs.  Though the land reform of the mid 18th century was aimed at breaking  up the large church holdings, it also forced the Indians to give up their  ejidos. The village lands were restored by the 1917 constitution.

It affects fishing, agriculture, and  local weather from Ecuador to Chile and can cause global climatic anoma�  lies in the equatorial Pacific, Asia, and North America. The name (Span�  ish for �the Christ Child�) was originally used by 19th-century Peruvian  fishermen to describe the annual flow of warm equatorial waters south�  ward around Christmastime. The term is now used for an intense ocean  warming that stretches from the western Pacific to South America. This  �anomalous occurrence� is caused by an unusual weakening of the nor�  mally westward-blowing trade winds, which in turn allows warm surface  waters to spread eastward.

The climate ranges from hot and wet in the low�  lands to cooler and wetter in the highlands. Cloud forests predominate at  the highest elevations. El Salvador has a developing economy based on  trade, manufacturing, and agriculture, with coffee, sugarcane, and cotton  the major export crops. It is a republic with one legislative house; its chief  of state and government is the president. The Spanish arrived in the area  in 1524 and subjugated the Pipil Indian kingdom of Cuzcatlan by 1539.  The country was divided into two districts, San Salvador and Sonsonate,  both attached to Guatemala. When Spanish rule ended in 1821, the Sal�  vadorans opposed incorporation into the Mexican Empire (confronting  both Guatemalan and Mexican armies), and, upon its collapse in 1823,  Sonsonate and San Salvador combined to form the new state of El Sal�  vador within the United Provinces of Central America. The country  attained independence in 1841. From its founding, it experienced a high  degree of political turmoil; powerful economic interests controlled the  country through most of the 19th and early 20th centuries but were  replaced by a military dictatorship that lasted from 1931 to 1979. Elec�  tions held in 1982 set up a new government, and, though a new consti�  tution was adopted in 1983, civil war continued throughout the 1980s. An  accord in 1992 brought peace, but violent crime became a major prob�  lem.

After he named his cousin Alex�  ander heir and then changed his mind, the Praetorian Guards mutinied,  murdered him, and made Alexander emperor.</p><p>Elam Ve-bm\ Ancient country of the Middle East. It was located in what  is now southwestern Iran, at the head of the Persian Gulf and east of</p><p>ancient Babylonia; its capital was Susa (the country, thus, is sometimes  known as Susiana). It had close cultural ties to Mesopotamia and was in  conflict with the Sumerians (see Sumer) and Akkadians (see Akkad) from  c. 3000 bc. In the 13th century bc, it became a dominant power that  included most of Mesopotamia east of the Tigris and reached almost to  Persepolis. Its domination ended when Nebuchadrezzar I of Babylon (r.  1124-1103 bc) captured Susa. Later, Elam formed a satrapy of the Per�  sian Achaemenian dynasty, and Susa became one of its capitals.</p><p>eland \'e-bnd\ Either of two species of easily tamed, oxlike antelope  (genus Taurotragus) found in herds  on the plains or in lightly wooded  areas of central and southern Africa.</p><p>The largest of the antelope, they may  stand up to 6 ft (1.8 m) tall at the  shoulder and weigh as much as 2,200  lbs (1,000 kg). They have a short,  dark mane, a dewlap hanging from  the throat, and long horns twisted in  a tight spiral. The common eland is  pale brown, becoming blue-gray  with age, and often marked with nar�  row, vertical white stripes. The giant,  or Derby, eland is reddish brown  with a blackish neck and vertical  white stripes and horns heavier than  those of the common eland.</p><p>elapid Ve-b-pod\ Any of about 200 species of venomous snakes (fam�  ily Elapidae) that have short fangs fixed in the front of the upper jaw.  Elapids are found in the New World, Africa, southern Asia, Pacific Islands,  and Australia. Slender and agile, most are small and harmless to humans,  but they include the largest and most lethal of snakes. Their venom is  primarily neurotoxic but often contains substances that damage body tis�  sues or blood cells. The relatively painless bite may cause a swift death  from paralysis of the heart and lungs. See also black snake, cobra, coral  SNAKE, MAMBA.</p><p>elastic modulus or elastic constant In materials science and physi�  cal metallurgy, any of various numbers that quantify the response of a  material to elastic or springy deflection. When tensile stress is applied to  a material, the resulting strain is determined by Young�s modulus (see  Thomas Young), a constant defined as the ratio of the stress in a body to  the corresponding strain. It has dimensions of (force)/(length) 2 and is  measured in units such as the pascal or newton per square meter (1 Pa =  1 N/m 2 ), dyne/cm 2 , or lbs per sq in. (psi). See also elasticity.</p><p>elasticity Ability of a deformed material body to return to its original  shape and size when the forces causing deformation are removed. Most  solids show some elastic behaviour, but there is usually a limit�the mate�  rial�s �elastic limit��to the force from which recovery is possible.  Stresses beyond its elastic limit cause the material to yield, or flow, and  the result is permanent deformation or breakage. The limit depends on the  material�s internal structure; for example, steel, though strong, has a low  elastic limit and can be extended only about 1% of its length, whereas  rubber can be elastically extended up to about 1,000%. Robert Hooke, one  of the first to study elasticity, developed a mathematical relation between  tension and extension.</p><p>Elba Island off the western coast of Italy, in the Tyrrhenian Sea. Occupy�  ing an area of 86 sq mi (223 sq km), it is the largest island of the Tuscan  Archipelago. France obtained Elba from Rome in 1802. When Napoleon  abdicated in May 1814, he was exiled to Elba. The island was recognized  as an independent principality with Napoleon as its ruler until February  1815, when he returned to France to begin the Hundred Days. Thereafter  Elba was restored to Tuscany.</p><p>Elbe Vel-boN River Czech Labe Vla-be\ ancient Albis River, central  Europe. One of the continent�s major waterways, it rises in the Krkonose  (Giant) Mountains on the border of the Czech Republic and Poland and  flows southwest across Bohemia. It then flows northwest across Germany  and empties into the North Sea near Cuxhaven. From 1945 to 1990 it  formed part of the boundary between East and West Germany. It is 724  mi ( 1 , 1 65 km) long and connected by canals with the Baltic Sea, the Havel  River and Berlin, the Ruhr industrial region, and the Rhine River. It is navi�  gable for 1,000-ton barges as far upstream as Prague through the Vltava  River.

Most are native to  forested temperate or subtropical  areas. Elders are important as garden  shrubs, as forest plants, and for their  berries (elderberries), which provide  food for wildlife and are used for  wines, jellies, pies, and folk medi�  cines. Elders have divided leaves and  flat, roundish clusters of tiny,  yellowish-white, saucer-shaped  flowers. The American, or sweet,  elder (5. canadensis) of North  America is the most important spe�  cies horticulturally.</p><p>elder, box See box elder</p><p>Elder, John (b.

Jan. 30, 1911, Pittsburgh, Pa., U.S.�d.  Feb. 26, 1989, Valley Stream, N.Y.) U.S. trumpeter, one of the most vital  and creative jazz musicians of the swing era. He was influenced by saxo�  phonists such as Coleman Hawkins and developed a fast, nimble technique  matched with harmonic sophistication. He played with Fletcher Henderson  (1935-36) and was featured with the big bands of Gene Krupa and Artie  Shaw in the 1940s. (A nickname reflecting his stature, �Little Jazz,� was  also the title of a record he made with Shaw). The dominant voice on his  instrument in the swing style, he exerted a strong influence on bebop musi�  cians.</p><p>Eleanor of Aquitaine (b. c. 1122�d. April 1, 1204, Fontevrault,  Anjou, Fr.) Queen consort of Louis VII of France (1137-80) and Henry II  of England (1152-89), the most powerful woman of 12th-century Europe.  She inherited the duchy of Aquitaine and married the heir to the French  throne. Beautiful, capricious, and strong-willed, she accompanied Louis  on the Second Crusade (1147-49), and her conduct aroused his jealousy.  The marriage was annulled (1152), and she married Henry Plantagenet,  soon to be Henry II; the marriage united England, Normandy, and west�  ern France under his rule. She bore Henry five sons, including the future  kings Richard I the Lionheart and John Lackland, and three daughters who  married into other royal houses. Her court at Poitiers became a centre of  culture, fostering the poetry of the troubadours. She may have spurred her  sons to revolt against Henry (1173); when the rebellion failed she was  captured and confined until his death (1189). She was active in govern�  ment during the reign of Richard I, ruling during his crusade to the Holy  Land and ransoming him from Austria. After Richard died (1199) and  John became king, she saved Anjou and Aquitaine for John against French  threats, then retired to the monastery at Fontevrault.</p><p>Eleanor of Castile (b. 1246�d. Nov. 28, 1290, Harby, Nottingham�  shire, Eng.) Queen consort of Edward I of England. Daughter of the king  of Castile, she brought Edward title to Gascony on their marriage in 1254,  and she was sent to France for safety during the baronial rebellion (1264-</p><p>65). She joined Edward on a crusade to the Holy Land (1270-73), and  legend says she saved his life by sucking poison from a dagger wound.  On her death, Edward erected Eleanor Crosses at each place where her  coffin rested en route to London.</p><p>Eleaticism V.el-e-'a-to-.si-zomX School of pre-Socratic philosophy that  flourished in the 5th century bc. It took its name from the Greek colony  of Elea (Velia) in southern Italy. It is distinguished by its radical MONISM�  i.e., its doctrine of the One, according to which all that exists is a static  plenum of Being as such, and nothing exists that stands either in contrast  or in contradiction to Being. Thus, all differentiation, motion, and change  must be illusory. Its literary sources consist of fragments (most less than  10 lines long) preserved by later Classical authors: 19 from Parmenides, 4  from his pupil Zeno of Elea, and 10 from another pupil, Melissus (fl. 5th  century bc). See also pre-Socratics.</p><p>Eleazar \,el-e- l a-zor\ ben Judah of Worms orig. Eleazar ben  Judah ben Kalonymos (b. 1160, Mainz, Franconia�d. 1238,  Worms) German Jewish mystic and Talmudic scholar. His wife and  daughters were killed by Crusaders in 1196, but he nevertheless contin�  ued to teach a doctrine of love of humanity. After studying with Judah ben  Samuel, to whom he was related, he became a rabbi at Worms (1201).  Eleazar attempted to unify the mysticism of the Kabbala with the Talmud.  His greatest work was his ethical code, Rokeah (1505). He believed that  God himself was unknowable but that the kavod, a ruling angel that was  an emanation from God, was knowable. His writings are a major source  of information on medieval Hasidism.</p><p>election Formal process by which voters make their political choices on  public issues or candidates for public office. The use of elections in the  modern era dates to the emergence of representative government in  Europe and North America since the 17th century. Regular elections serve  to hold leaders accountable for their performance and permit an exchange  of influence between the governors and the governed. The availability of  alternatives is a necessary condition. Votes may be secret or public. See  also ELECTORAL SYSTEM, PARTY SYSTEM, PLEBISCITE, PRIMARY ELECTION, REFERENDUM AND  INITIATIVE.</p><p>elector German Kurfurst. Prince of the Holy Roman Empire who had a  right to participate in electing the German emperor. Beginning c. 1273,  and with the confirmation of the Golden Bull, there were seven electors:  the archbishops of Trier, Mainz, and Cologne; the duke of Saxony; the  count palatine of the Rhine; the margrave of Brandenburg; and the king  of Bohemia. Other electorates were created much later for Bavaria (1623�  1778), Hanover (1708), and Hesse-Kassel (1803), but by the 17th century  the electors� office had become meaningless because the Habsburg dynasty  produced the de facto emperors. The office disappeared when the empire  was abolished in 1806.</p><p>electoral college Constitutionally mandated process for electing the  U.S. president and vice president. Each state appoints as many electors as  it has senators and representatives in Congress (U.S. senators, represen�  tatives, and government officers are ineligible); the District of Columbia  has three votes. A winner-take-all rule operates in every state except  Maine and Nebraska. Three presidents have been elected by means of an  electoral college victory while losing the national popular vote (Ruther�  ford B. Hayes in 1877, Benjamin Harrison in 1888, and George W. Bush in  2000). Though pledged to vote for their state�s winners, electors are not  constitutionally obliged to do so. A candidate must win 270 of the 538  votes to win the election.</p><p>Electoral Commission (1877) Commission created to resolve the  disputed 1876 presidential election between Republican Rutherford B.  Hayes and Democrat Samuel Tilden. Tilden had won the popular vote and  was only one electoral vote short of victory, but the Republicans contested  the tallies in four states, charging fraud. Unable to reach a consensus,  Congress appointed a 15-member commission, evenly divided between  the two parties, except for one justice, Joseph R Bradley, a Republican  considered nonpartisan; Republicans pressured him, and the tally went to  Hayes, who was declared the winner on March 2.

Originating in  the 1880s, electric cars were used for private passenger, truck, and bus  transportation in cities, where their low speeds and limited battery range  were not drawbacks, and the cars became popular for their quietness and  low maintenance costs. Until 1920 they were competitive with gasoline-  fueled cars; they became less so after the electric self-starter made  gasoline-powered cars more attractive and mass production made them  cheaper to produce. In Europe electric vehicles have been used as short-  range delivery vans. Renewed interest in electric cars beginning in the  1970s, spurred especially by new consciousness of foreign oil dependency  and environmental concern, led to improvements in speed and range.  Recent laws, particularly in California, have mandated commercial pro�  duction. �Hybrid� cars employing both electric and internal combustion  engines and providing the best features of both technologies, have recently  become commercially available. Experimental vehicles have used solar  FUEL CELLS.</p><p>electric charge Quantity of electricity that flows in electric currents or  that accumulates on the surfaces of dissimilar nonmetallic substances that  are rubbed together briskly. It occurs in discrete natural units, equal to the  charge of an electron or proton. It cannot be created or destroyed. Charge  can be positive or negative; one positive charge can combine with one  negative charge, and the result is a net charge of zero. Two objects that  have an excess of the same type of charge repel each other, while two  objects with an excess of opposite charge attract each other. The unit of  charge is the coulomb, which consists of 6.24 x 10 18 natural units of elec�  tric charge.</p><p>electric circuit See circuit</p><p>electric current Movement of electric charge carriers. In a wire, elec�  tric current is a flow of electrons that have been dislodged from atoms and  is a measure of the quantity of electrical charge passing any point of the  wire per unit time. Current in gases and liquids generally consists of a  flow of positive ions in one direction together with a flow of negative ions  in the opposite direction. Conventionally, the direction of electric current  is that of the flow of the positive ions. In alternating current (AC) the  motion of the charges is periodically reversed; in direct current (DC) it is  not. A common unit of current is the ampere, a flow of one coulomb of  charge per second, or 6.24 x 10 18 electrons per second.</p><p>electric dipole VdI-pol\ Pair of equal and opposite electric charges, the  centres of which do not coincide. An atom in which the centre of the  negative cloud of electrons has been shifted slightly away from the nucleus  by an external electric field is an induced electric dipole. When the exter�  nal field is removed, the atom loses its dipolarity. A water molecule, in  which two hydrogen atoms are situated to one side of an oxygen atom, is  a permanent electric dipole. The oxygen side is always slightly negative,  the hydrogen side slightly positive.</p><p>electric discharge lamp o/ vapor lamp Lighting device consist�  ing of a transparent container within which a gas is energized by an  applied voltage and made to glow. After practical generators were devised  in the 19th century, many experimenters applied electric power to tubes  of gas. From c. 1900, electric discharge lamps were in use in Europe and  the U.S. Fluorescent, neon, mercury, sodium, and metal-halide lamps are  of the electric discharge variety.</p><p>electric eel Eel-shaped South American fish (Electrophones electricus )  capable of producing an electric shock strong enough to stun a human. The  electric eel (not a true eel) is a sluggish inhabitant of slow freshwater, sur�  facing periodically to gulp air. Long, cylindrical, scaleless, and gray-  brown, it sometimes reaches a length of 9 ft (2.75 m) and a weight of 49 lbs  (22 kg). The tail region, bordered below by a long anal fin that the fish</p><p>undulates to move about, contains the electric organs. The shock (up to 650  volts discharged at will) is used mainly to immobilize fish and other prey.</p><p>electric eye See photocell</p><p>electric field Region around an electric charge in which an electric force  is exerted on another charge. The strength of an electric field E at any  point is defined as the electric force F exerted per unit positive electric  charge q at that point, or E = F/q. An electric field has both magnitude  and direction and can be represented by lines of force, or field lines, that  start on positive charges and terminate on negative charges. The electric  field is stronger where the field lines are close together than where they  are farther apart. The value of the electric field has dimensions of force  per unit charge and is measured in units of newtons per coulomb.</p><p>electric force or Coulomb force Force between two electric charges.  The magnitude of the force F is proportional to the product of the two  charges, q 1 and q 2 , divided by the square of the distance r between them,  or F = kq^q-Jr 1 , where k is a constant that depends on the measurement  system being used. The electric force can be one of repulsion, such as the  force between two objects having like charges, or it can be attractive, such  as the force between two objects having opposite charges.</p><p>electric furnace Chamber heated with electricity to very high tem�  peratures, for melting and alloying metals and refractories. Modern elec�  tric furnaces generally are either arc furnaces or induction furnaces. Arc  furnaces produce roughly two-fifths of the steel made in the U.S. In the  induction furnace, a coil carrying alternating electric current surrounds  the container or chamber of metal; circulating eddy currents induced in  the metal produce extremely high temperatures.</p><p>electric potential Amount of work needed to move a unit electric  charge from a reference point to a specific point against an electric field.  The potential energy of a positive charge increases when it moves against  an electric field, and decreases when it moves with the field. Electric  potential can be thought of as potential energy per unit charge. The work  done in moving a unit charge from one point to another, as in an electric  circuit, is equal to the difference in potential energies at each point. Elec�  tric potential is expressed in units of joules per coulomb, or volts.</p><p>electric ray Any of the aquatic rays (families Torpedinidae, Narkidae,  and Temeridae) that produce an electrical shock. They are found world�  wide in warm and temperate seas, mostly in shallow water but some  (genus Benthobatis) at depths greater than 3,000 ft (900 m). Slow-moving  bottom-dwellers, they feed on fishes and invertebrates. They range in  length from less than 1 ft (30 cm) to about 6 ft (1.8 m) and have a short,  stout tail. They are soft and smooth-skinned, with a circular or nearly cir�  cular body disk formed by the head and pectoral fins. They are harmless  unless touched or stepped on. The electric organs, composed of modified  muscle tissue, are in the disk near the head. The shock from these organs,  which may reach 220 volts and is strong enough to fell a human adult, is  used for defense, sensory location, and capturing prey.</p><p>Electric ray (Narcine brasiliensis)</p><p>DOUGLAS FAULKNER</p><p>electric shock Physical effect of an electric current that enters the body,  ranging from a minor static-electricity discharge to a power-line accident  or lightning strike but most often resulting from house current.

Though  most survivors recover completely, aftereffects may include cataract,  angina pectoris, or nervous-system disorders.</p><p>electrical engineering Branch of engineering concerned with the  practical applications of electricity in all its forms, including those of elec�  tronics. Electrical engineering deals with electric light and power systems  and apparatuses; electronics engineering deals with wire and radio com�  munication, the stored-program electronic computer, radar, and automatic  control systems. The first practical application of electricity was the tele�  graph, in 1837. Electrical engineering emerged as a discipline in 1864  when James Clerk Maxwell summarized the basic laws of electricity in  mathematical form and predicted that radiation of electromagnetic energy  would occur in a form that later became known as radio waves. The need  for electrical engineers was not felt until the invention of the telephone  (1876) and the incandescent lamp (1878).</p><p>electrical impedance \im-'pe-d 3 ns\ Opposition that a circuit presents  to electric current. It includes both resistance and reactance. Resistance  arises from collisions of the current-carrying charged particles with the  internal structure of the conductor. Reactance is an additional opposition  to the movement of electric charge that arises from the changing electric  and magnetic fields in circuits carrying alternating current. Impedance in  circuits carrying steady direct currents is simply resistance. The magni�  tude of the impedance Z of a circuit is equal to the maximum value of  the potential difference, or voltage V, across the circuit, divided by the  maximum value of the current I through the circuit, or simply Z = VII.  The unit of impedance is the ohm.</p><p>electricity Phenomenon associated with stationary or moving electric  charges. The word comes from the Greek elektron (�amber�); the Greeks  discovered that amber rubbed with fur attracted light objects such as  feathers. Such effects due to stationary charges, or static electricity, were  the first electrical phenomena to be studied. Not until the early 19th cen�  tury were static electricity and electric current shown to be aspects of the  same phenomenon. The discovery of the electron, which carries a charge  designated as negative, showed that the various manifestations of elec�  tricity are the result of the accumulation or motion of numbers of elec�  trons. The invention of the incandescent lightbulb (1879) and the  construction of the first central power station (1881) by Thomas Alva Edi�  son led to the rapid introduction of electric power into factories and  homes.

Electrocardiograms (ECGs) are made by applying electrodes, usually to  the arms, legs, and chest wall, attached to an electrocardiograph, which  records the tiny heart current. Upward and downward movements on the  tracing reflect contractions of the atria and ventricles. Deviations from a  standard point to a possible heart disorder and its site, as well as to pos�  sible high blood pressure and other diseases.</p><p>electrochemistry Branch of chemistry concerned with the relation  between electricity and chemical change. Many spontaneous chemical reac�  tions liberate electrical energy, and some of these reactions are used in  batteries and fuel cells to produce electric power. Conversely, electric cur�  rent can bring about many reactions that do not occur spontaneously. In  the process called electrolysis, electrical energy is converted directly into  chemical energy, which is stored in the products of the reaction. This pro�  cess is applied in refining metals, in electroplating, and in producing  hydrogen and oxygen from water. Passage of electricity through a gas  generally causes chemical changes, a subject that forms a separate branch  of electrochemistry. See also oxidation-reduction.</p><p>electroconvulsive therapy formerly shock therapy Method of  treating psychiatric disorders by inducing shock through electric current.  Electroconvulsive, or electroshock, therapy involves passing an electric  current through the patient�s head between two electrodes placed over the  temples and thus causing a convulsive seizure; it was used to treat bipolar  disorder and other types of depression. Shock was previously induced by  administering increasingly large doses of insulin until the patient was  thrown into a brief coma; the so-called insulin-shock therapy was used</p><p>for the treatment of schizophrenia. Both forms of shock therapy were devel�  oped in the 1930s. Their use declined after the introduction of tranquil-  izing drugs and antidepressants.</p><p>electrocution Method of execution in which the condemned person is  subjected to a heavy charge of electric current. The prisoner is shackled  into a wired chair, and electrodes are fastened to the head and one leg so  that the current will flow through the body. One electrical shock may not  be enough to kill the person; if a doctor does not confirm the death, sev�  eral shocks may be applied. The electric chair was first used in 1890.  Electrocution also refers to death by other causes of electrical shock (e.g.,  accidental contact with high-voltage wiring).</p><p>electrode Electric conductor, usually metal, used as one of two termi�  nals to conduct electric current through a conducting medium. A simple  voltaic cell, or battery, consists of two electrodes, usually one zinc and  one copper, immersed in an electrolytic solution (see electrolyte). When a  chemical reaction occurs in the solution, electrons gather on the zinc elec�  trode, or cathode, which becomes negatively charged. At the same time,  electrons are drawn from the copper electrode, the anode, giving it a posi�  tive charge. The difference in charge sets up a potential difference, or  voltage, between the two electrodes. When they are connected by a con�  ducting wire, electrons flow from the cathode to the anode, producing a  current.</p><p>electrodynamics, quantum See quantum electrodynamics</p><p>electroencephalography U-.lek-tro-in-.sef-o-Tag-ro-feV Technique  for recording electrical activity in the brain, whose cells emit distinct pat�  terns of rhythmic electrical impulses. Pairs of electrodes on the scalp  transmit signals to an electroencephalograph, which records them as peaks  and troughs on a tracing called an electroencephalogram (EEG). Differ�  ent wave patterns on the EEG are associated with normal and abnormal  waking and sleeping states. They help diagnose conditions such as  tumours, infections, and epilepsy. The electroencephalograph was  invented in the 1920s by Hans Berger (1873-1941).</p><p>electrolysis \i-,lek-'tra-l9-s3s\ Process in which electric current passed  through a substance causes a chemical change, usually the gaining or losing  of electrons (see oxidation-reduction). It is carried out in an electrolytic cell  consisting of separated positive and negative electrodes (anode and cath�  ode, respectively) immersed in an electrolyte solution containing ions or in  a molten ionic compound. Electric current enters through the cathode; posi�  tively charged cations travel to it and combine with electrons. Negatively  charged anions give up electrons at the anode. Both thus become neutral  molecules. Electrolysis is used extensively in metallurgy to extract or purify  metals from ores or compounds and to deposit them from solution (electro�  plating). Electrolysis of molten sodium chloride yields metallic sodium and  chlorine gas; that of a strong solution of sodium chloride in water (brine)  yields hydrogen gas, chlorine gas, and sodium hydroxide (in solution); and  that of water (with a low concentration of dissolved sodium chloride or  other electrolyte) yields hydrogen and oxygen.</p><p>electrolyte Substance that conducts electric current as a result of disso�  ciation of its molecules into positively and negatively charged particles  called ions. The most familiar electrolytes are acids, bases, and salts, which  ionize when dissolved in polar solvents such as water. Many salts, includ�  ing sodium chloride, behave as electrolytes when melted in the absence of  solvent, since they have ionic bonds. The most commonly used electro�  lytes are dissolved metal salts (for electroplating metals) and acids (in  electric batteries). See also electrolysis.</p><p>electromagnet Device consisting of a core of magnetic material such  as iron, surrounded by a coil through which an electric current is passed to  magnetize the core. When the current is stopped, the core is no longer mag�  netized. Electromagnets are particularly useful wherever controllable mag�  nets are required, as in devices in which the magnetic field is to be varied,  reversed, or switched on and off. Suitably designed magnets can lift many  times their own weight and are used in steelworks and scrap yards to lift  loads of metal. Other devices that utilize electromagnets include particle  accelerators, telephone receivers, loudspeakers, and televisions.</p><p>electromagnetic field Property of space caused by the motion of an  electric charge. A stationary charge produces an electric field in the sur�  rounding space. If the charge is moving, a magnetic field is also produced.  A changing magnetic field also produces an electric field. The interaction  of electric and magnetic fields produces an electromagnetic field, which</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>electromagnetic force &#x25BA; electronic music I 609</p><p>has its own existence in space apart from the charges involved. An elec�  tromagnetic field can sometimes be described as a wave that transports  ELECTROMAGNETIC RADIATION.</p><p>electromagnetic force One of the four known basic forces in the  universe. Electromagnetism is responsible for interactions between  charged particles that occur because of their charge, and for the emission  and absorption of photons (electromagnetic radiation). The phenomena of  electricity and magnetism are consequences of this force, and the relation�  ships between them were first described by James Clerk Maxwell in the  1860s. The physical description of electromagnetism has since been com�  bined with quantum mechanics into the theory of quantum electrodynamics.  The electromagnetic force is about 10 36 times as strong as the gravita�  tional force (see gravitation), but significantly weaker than both the weak  force and the strong force.</p><p>electromagnetic induction Induction of an electromotive force in a  circuit by varying the magnetic flux linked with the circuit. The phenom�  enon was first investigated in 1830-31 by Joseph Henry and Michael Fara�  day, who discovered that when the magnetic field around an electromagnet  was increased or decreased, an electric current could be detected in a sepa�  rate nearby conductor. A current can also be induced by constantly mov�  ing a permanent magnet in and out of a coil of wire, or by constantly  moving a conductor near a stationary permanent magnet. The induced  electromotive force is proportional to the rate of change of the magnetic  flux cutting across the circuit.</p><p>electromagnetic radiation Energy propagated through free space  or through a material medium in the form of electromagnetic waves.  Examples include radio waves, infrared radiation, visible light, ultraviolet  radiation, X rays, and gamma rays. Electromagnetic radiation exhibits  wavelike properties such as reflection, refraction, diffraction, and interfer�  ence, but also exhibits particlelike properties in that its energy occurs in  discrete packets, or quanta. Though all types of electromagnetic radiation  travel at the same speed, they vary in frequency and wavelength, and inter�  act with matter differently. A vacuum is the only perfectly transparent  medium; all others absorb some frequencies of electromagnetic radiation.</p><p>electromagnetic spectrum Total range of frequencies or wavelengths  of electromagnetic radiation. The spectrum ranges from waves of long  wavelength (low frequency) to those of short wavelength (high fre�  quency); it comprises, in order of increasing frequency (or decreasing  wavelength): very-low-frequency to ultrahigh-frequency radio waves,  MICROWAVES, INFRARED RADIATION, visible UGHT, ULTRAVIOLET RADIATION, X-RAYS,  and gamma rays. In a vacuum, all waves of the electromagnetic spectrum  travel at the same speed: 299,792,458 m/sec (186,282 mi/sec).</p><p>red orange yellow green blue violet</p><p>microwaves ultraviolet gamma rays</p><p>radio, TV waves infrared x-rays</p><p>The spectrum of electromagnetic waves ranges from low-frequency radio waves to  high-frequency gamma rays. Only a small portion of the spectrum, representing  wavelengths of roughly 400-700 nanometers, is visible to the human eye.</p><p>� MERRIAM-WEBSTER INC.</p><p>electromagnetism Branch of physics that deals with the relationship  between electricity and magnetism. Their merger into one concept is tied to  three historical events. Hans C. Orsted�s accidental discovery in 1820 that  magnetic fields are produced by electric currents spurred efforts to prove  that magnetic fields can induce currents. Michael Faraday showed in 1831  that a changing magnetic field can induce a current in a circuit, and James  Clerk Maxwell predicted that a changing electric field has an associated</p><p>magnetic field. The technological revolution attributed to the development  of electric power and modem communications can be traced to these three  landmarks.</p><p>electromotive force Energy per unit electric charge that is imparted  by an energy source, such as an electric generator or a battery. As the  device does work on the electric charge being transferred within itself,  energy is converted from one form to another. The work done on a unit  of electric charge or the energy gained by the unit charge is the electro�  motive force emf (or E ) and is characteristic of any energy source capable  of driving electric charge around a circuit. A common unit of electromo�  tive force is the volt V, a unit equal to the difference in electric potential  between two points in a conductor carrying a current of one ampere and  dissipating one watt of power between the two points.</p><p>electromyography U-.lek-tro-ml-'ag-ro-feN Process of graphically  recording the electrical activity of muscle, which normally generates an  electric current only when contracting or when its nerve is stimulated.  Electrical impulses are shown as wavelike tracings on an oscilloscope and  recorded as an electromyogram (EMG), usually along with audible sig�  nals. The EMG can show whether muscle weakness or wasting is due to  nerve impairment (as in amyotrophic lateral sclerosis and poliomyelitis) or  muscle impairment or disease (myopathy).</p><p>electron Lightest electrically charged subatomic particle known. It car�  ries a negative charge (see electric charge), the basic charge of electricity.  An electron has a small mass, less than 0.1% the mass of an atom. Under  normal circumstances, electrons move about the nucleus of an atom in  orbitals that form an electron cloud bound in varying strengths to the posi�  tively charged nucleus. Electrons closer to the nucleus are held more  tightly. The first subatomic particle discovered, the electron was identi�  fied in 1897 by J. J. Thomson.</p><p>electron microscopy \ml-'kras-k3-pe\ Technique that allows exami�  nation of samples too small to be seen with a light microscope. Electron  beams have much smaller wavelengths than visible light and hence higher  resolving power. To make them more observable, samples may be coated  with metal atoms. Because electrons cannot travel very far in air, the elec�  tron beam and the sample must be kept in a vacuum. Two different instru�  ments are used. In the scanning electron microscope, a moving beam of  electrons is scanned across a sample; electrons scattered by the object are  focused by magnetic �lenses� to produce an image of the object�s surface  similar to an image on a television screen. The images appear three-  dimensional; they may be of small organisms or their parts, of molecules  such as DNA, or even of large individual atoms (e.g., uranium, thorium).  In the transmission electron microscope, the electron beam passes through  a very thin, carefully prepared sample and is focused onto a screen or  photographic plate to visualize the interior structure of such specimens as  cells and tissues.</p><p>electron paramagnetic resonance See electron spin resonance</p><p>electron spin resonance (ESR) or electron paramagnetic  resonance (ERR) Technique of spectroscopic analysis (see spectros�  copy) used to identify paramagnetic substances (see paramagnetism) and  investigate the nature of the bonding within molecules by identifying  unpaired electrons and their interaction with their immediate surround�  ings. Unpaired electrons, because of their spin, behave like tiny magnets  and can be lined up in an applied magnetic field; energy applied by alter�  nating microwave radiation is absorbed when its frequency coincides with  that of precession of the electron magnets in the sample. The graph or  spectrum of radiation absorbed as the field changes gives information  valuable in chemistry, biology, and medicine.</p><p>electronic banking Use of computers and telecommunications to  enable banking transactions to be done by telephone or computer rather  than through human interaction. Its features include electronic funds  transfer for retail purchases, automatic teller machines (ATMs), and auto�  matic payroll deposits and bill payments. Some banks offer home bank�  ing, whereby a person with a personal computer can make transactions,  either via a direct connection or by accessing a Web site. Electronic bank�  ing has vastly reduced the physical transfer of paper money and coinage  from one place to another or even from one person to another.</p><p>electronic mail See E-mail</p><p>electronic music Any music involving electronic processing (e.g.,  recording and editing on tape) and whose reproduction involves the use</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>610 I electronics &#x25BA; elephant bird</p><p>of loudspeakers. In the late 1940s, magnetic tape began to be used, espe�  cially in France, to modify natural sounds (playing them backward, at dif�  ferent speeds, etc.), creating the genre known as musique concrete. By  the early 1950s, composers in Germany and the U.S. were employing  assembled conglomerations of oscillators, filters, and other equipment to  produce entirely new sounds. The development of voltage-controlled  oscillators and filters led, in the 1950s, to the first synthesizers, which  effectively standardized the assemblages and made them more flexible.  No longer relying on tape editing, electronic music could now be created  in real time. Since their advent in the late 1970s, personal computers have  been used to control the synthesizers. Digital sampling�composing with  music and sounds electronically extracted from other recordings�has  largely replaced the use of oscillators as a sound source.</p><p>electronics Branch of physics that deals with the emission, behaviour,  and effects of electrons and with electronic devices. The beginnings of  electronics can be traced to experiments with electricity. In the 1880s Tho�  mas Alva Edison and others observed the flow of current between elements  in an evacuated glass tube. A two-electrode vacuum tube constructed by  John A. Fleming (1849-1945) produced a useful output current. The  Audion, invented by Lee De Forest (1907), was followed by further  improvements. The invention of the transistor at Bell Labs (1947) initi�  ated a progressive miniaturization of electronic components that by the  mid 1980s resulted in high-density microprocessors, which in turn led to  tremendous advances in computer technology and computer-based auto�  mated systems. See also semiconductor.</p><p>electrophile Atom or molecule that in a chemical reaction seeks an atom  or molecule containing an electron pair available for bonding or the nega�  tive end of a polar molecule (see covalent bond; electric dipole). In the  Lewis electron theory (see acid-base theory) advanced by the U.S. chem�  ist Gilbert Lewis (1875-1946) in 1923, electrophiles are by definition  Lewis acids. Examples include the hydronium ion (H 3 0 + ), boron triflu�  oride (BF 3 ), and the halogens fluorine, chlorine, bromine, and iodine in  molecular form. See also acid; nucleophile.</p><p>electrophoresis Ni-.lek-tro-fo-'re-sosX Movement of electrically  charged particles in a fluid under the influence of an electric field. The par�  ticles migrate toward the electrode of the opposite electric charge, often on  a gel-coated slab or plate, sometimes in a fluid flowing down a paper.  Originated about 1930 by Arne Tiselius (1902-1971) as a technique for  analysis, electrophoresis is used to analyze and separate colloids (e.g., pro�  teins) or deposit coatings.</p><p>electroplating Process of coating with metal by means of an electric  current. Plating metal may be transferred to conductive surfaces (e.g.,  metals) or to nonconductive surfaces (e.g., plastics, wood, leather) if a  conductive coating has been applied. Usually the current deposits a given  amount of metal on the cathode (workpiece) and the anode (source of  metal) dissolves to the same extent, maintaining a fairly uniform solution.  Silver plating is used on tableware, electrical contacts, and engine bear�  ings. The most extensive use of gold plating is on jewelry and watch cases.  Zinc coatings prevent the corrosion of steel articles, and nickel and chro�  mium plate are used on automobiles and household appliances. See also  TERNEPLATE, SHEFFIELD PLATE.</p><p>electrostatic induction Modification in the distribution of electric  charge on one material under the influence of an electric charge on a  nearby object. It occurs whenever any object is placed in an electric field.  When a negatively charged object is brought near a neutral object, it  induces a positive charge on the near side of the object and a negative  charge on the far side. If the negative side of the original object is momen�  tarily grounded, the negative charge may escape, so that the object  becomes positively charged by induction.</p><p>electroweak theory Theory that describes both the electromagnetic  force and the weak force. Though the forces appeal' to be different, they  are actually different facets of a more fundamental force. This theory, for�  mulated in the 1960s by Sheldon Glashow (bom 1932), Steven Weinberg  (born 1933), and Abdus Salam (born 1926), represents a 20th-century sci�  entific landmark and won its authors a 1979 Nobel Prize. It was validated  in the 1980s with the discovery of the W particle and Z particle, which it  had predicted. See also fundamental interaction, unified field theory.</p><p>electrum Natural or artificial alloy of gold with at least 20% silver, used  to make the first known coins in the Western world. Most natural elec-  trum also contains copper, iron, palladium, bismuth, and perhaps other</p><p>metals. The colour varies from white-gold to brassy, depending on the  percentages of the major constituents and copper. The first Western coin�  age, possibly begun by King Gyges of Lydia (7th century bc), consisted  of irregular ingots of electrum bearing his stamp as a guarantee of nego�  tiability at a predetermined value. See also coinage.</p><p>elegy Ve-l9-je\ Meditative lyric poem. The classical elegy was any poem  written in elegiac metre (alternating lines of dactylic hexameter and pen�  tameter). Today the term may refer to this metre rather than to content,  but in English literature since the 16th century it has meant a lament in  any metre. A distinct variety with a formal pattern is the pastoral elegy,  such as John Milton�s �Lycidas� (1638). Poets of the 18th-century Grave�  yard School reflected on death and immortality in elegies, most famously  Thomas Gray�s �An Elegy Written in a Country Church Yard� (1751).</p><p>element, chemical One of the more than 110 presently known kinds  of substances that constitute all matter at and above the level of atoms (the  smallest units of any element). All atoms of an element are identical in  nuclear charge (number of protons) and number of electrons (see atomic  number), but their mass (atomic weight) may differ if they have different  numbers of neutrons (see isotope). Each permanently named element has  a one- or two-letter chemical symbol. Elements combine to form a wide  variety of compounds. All elements with atomic numbers greater than 83  (bismuth), and some isotopes of lighter elements, are unstable and radio�  active (see radioactivity). The transuranium elements, with atomic numbers  greater than 92 (see uranium), artificially created by bombardment of other  elements with neutrons or other particles, were discovered beginning in  1940. The most common elements (by weight) in Earth�s crust are oxy�  gen, 49%; silicon, 26%; aluminum, 8%; and iron, 5%. Of the known ele�  ments, 11 (hydrogen, nitrogen, oxygen, fluorine, chlorine, and the six  noble gases) are GASes under ordinary conditions, two (bromine and mer�  cury) are liquids (two more, cesium and gallium, melt at about or just  above room temperature), and the rest are solids.

Often preceded by some form of preschool, it usually includes  middle school, or junior high school (ages 11-13), though this is some�  times regarded as part of secondary education. Nearly all nations are com�  mitted to some form of elementary education, though in many developing  countries many children are unable to continue full-time studies past the  age of 10 or 11. The elementary curriculum usually emphasizes reading  and writing, arithmetic, social studies, and science. A basic teaching strat�  egy involves moving the student from the immediate and familiar to the  distant and unfamiliar, an approach first formulated by Johann Heinrich  Pestalozzi.</p><p>elementary particle See subatomic particle</p><p>elephant Any of three ungulate species in the order Proboscidea (fam�  ily Elephantidae), characterized by  their large size, long trunk, tusks,  massive legs, large ears, and huge  head.

June 2, 1857, Broadheath, Worces�  tershire, Eng.�d. Feb. 23, 1934, Worcester, Worcestershire) British com�  poser. Son of a piano tuner, he became proficient on violin and organ. His  Enigma Variations (1896) brought him fame; he followed it with the ora�  torio The Dream of Gerontius (1900), which many consider his master�  piece. He composed in the orchestral idiom of late 19th-century  Romanticism�characterized by bold tunes, striking colour effects, and</p><p>mastery of large forms�stimulating a renaissance of English music. His  principal works include the five Pomp and Circumstance Marches (1901�  07), two symphonies (1908, 1911), concertos for violin (1910) and cello  (1919), and the tone poems Cockaigne (1901) and Falstaff { 1913).</p><p>Elgin Vel-ganX, James Bruce, 8th earl of (b. July 20, 1811, Lon�  don, Eng.�d. Nov. 20,1863, Dharmshala, India) British governor-general  of Canada. He was appointed governor of Jamaica in 1842. As governor  of British North America (1847-54), he implemented the policy of respon�  sible, or cabinet, government recommended by Lord Durham. Elgin sup�  ported the Rebellion Losses Act (1849), which compensated Canadians  for losses during the 1837 rebellion in Lower Canada, a stand criticized</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Elgin Marbles &#x25BA; Eliot I 613</p><p>by Tory opponents in England and French-Canadian rioters in Montreal.  He negotiated the Reciprocity Treaty (1854) between the Canadian colo�  nies and the U.S. In 1857 he left Canada to serve in diplomatic posts in  China, Japan, and India.</p><p>Elgin Marbles Vel-gon\ Collection of ancient Greek marble sculptures  and architectural fragments in the  British Museum. They were removed  from the Parthenon in Athens and  other buildings by Thomas Bruce,</p><p>Lord Elgin (1766-1841), ambassa�  dor to the Ottoman Empire, and  shipped to England between 1802  and 1811. Elgin claimed he was sav�  ing the works from destruction by  the Turks, who then controlled  Greece. He secured permission from  the Turks to remove �any pieces of  stone� bearing figures or inscrip�  tions. They remained in his private  possession, amid mounting criticism,  until 1816, when the crown bought  them. The controversy still contin�  ues; the Greek government fre�  quently demands their return.</p><p>Elgon Vel-,gan\, Mount Extinct  volcano on the Kenya-Uganda border. Located northeast of Lake Victo�  ria, its crater, about 5 mi (8 km) in diameter, contains several peaks, of  which Wagagai, at 14,178 ft (4,321 m), is the highest. The Bantu-speaking  Gishu (Gisu) occupy the mountain�s western slopes.</p><p>Eliade \,el-e-'a-da\, Mircea (b. March 9, 1907, Bucharest, Rom.�d.  April 22, 1986, Chicago, Ill., U.S.) Romanian-born U.S. historian of reli�  gion. He studied Sanskrit and Indian philosophy at the University of Cal�  cutta, then returned to complete his Ph.D. at the University of Bucharest,  where he taught until 1939. In 1945 he moved to Paris to teach at the  Sorbonne, and from 1956 he taught at the University of Chicago. Eliade  considered religious experiences to be credible phenomena, manifesta�  tions of the sacred in the world, and his work traced the forms they have  taken throughout the world and through time. He founded the journal  History of Religions in 1961. His books include The Myth of the Eternal  Return (1949) and A History of Religious Ideas (3 vol., 1978-85); he  edited the 16-volume Encyclopedia of Religion (1987).</p><p>Elijah \i-'lI-jo\ or Elias Hebrew Eliyyahu (fl. 9th century bc) Hebrew  prophet. The Bible related that he denounced foreign cults and defeated  450 prophets of Baal in a contest on Mount Carmel. In doing so, he earned  the enmity of King Ahab and his consort, Jezebel, who forced him to flee  into the wilderness. Later he was taken up into heaven in a whirlwind,  leaving behind his successor, Elisha. His insistence that only the God of  Israel is entitled to the name of divinity expresses a fully conscious mono�  theism. He is also recognized as a prophet in Islam.</p><p>Elijah ben Solomon (b. April 23, 1720, Sielec, Lith., Russian  Empire�d. Oct. 9, 1797, Vilna) Lithuanian scholar and Jewish leader.  Born into a long line of scholars, he traveled in Poland and Germany  before settling in Vilna, the cultural centre of eastern European Jewry. He  refused rabbinic office and lived as a recluse while devoting himself to  study and prayer, but he nevertheless became famous and revered in the  Jewish community. His scholarly interests included biblical exegesis, Tal�  mudic studies, folk medicine, grammar, and philosophy. A vehement  opponent of Hasidism, he denounced its claims to miracles, visions, and  spiritual ecstasy, calling instead for the intellectual love of God.</p><p>Elion \'e-le-3n\, Gertrude (Belle) (b. Jan. 23, 1918, New York, N.Y.,  U.S.�d. Feb. 21, 1999, Chapel Hill, N.C.) U.S. pharmacologist. She  graduated from Hunter College. Unable to find a research position because  of her sex, she initially taught high school chemistry. In 1944 she became  George Herbert Hitchings�s assistant at Burroughs Wellcome. They devel�  oped drugs for leukemia, autoimmune disorders, urinary-tract infections,  gout, malaria, and viral herpes using innovative research methods. They  examined the biochemistry of normal human cells and of disease-causing  agents and used the results to formulate drugs that could kill or inhibit  reproduction of a particular pathogen but leave normal host cells  unharmed. In 1988 they shared a Nobel Prize with James Black.</p><p>Eliot, Charles William (b. March 20, 1834, Boston, Mass., U.S.�d.  Aug. 22, 1926, Northeast Harbor, Maine) U.S. educator and influential  university president. He studied at Harvard University and taught math�  ematics and chemistry there (1858-63) and at MIT (1865-69). Eliot was  named president of Harvard in 1869 after studying European educational  systems, and he soon set about a program of fundamental reforms. He  demanded a place for the sciences in liberal education, and he replaced  the program of required courses for undergraduates with the elective sys�  tem. Under Eliot, the graduate school of arts and sciences was created  (1890), Radcliffe College was established (1894), the quality of the pro�  fessional schools was raised, and the university became an institution of  world renown. His reforms had widespread influence in American higher  education. After resigning in 1909, he edited the 50-volume Harvard  Classics (1909-10), wrote several books, and devoted himself to public  service.</p><p>Eliot, George orig. Mary Ann Evans later Marian Evans (b.</p><p>Nov. 22, 1819, Chilvers Coton, War�  wickshire, Eng.�d. Dec. 22, 1880,</p><p>London) British novelist. Eliot was  raised with a strong evangelical piety  but broke with religious orthodoxy  in her 20s. She worked as a transla�  tor, a critic, and a subeditor of the  Westminster Review (1851�54).</p><p>Later she turned to fiction. Adopting  a masculine pseudonym to evade  prejudice against women novelists,  she first brought out Scenes of Cleri�  cal Life (1858). This was followed  by such classic works as Adam Bede  (1859), The Mill on the Floss (1860),</p><p>Silas Marne r (1861), Romo la (1862-  63), Felix Holt, the Radical (1866),  and Daniel Deronda (1876). Her  masterpiece, Middlemarch (1871�</p><p>72), provides a thorough study of  every class of provincial society. The  method of psychological analysis  she developed would become char�  acteristic of modern fiction. With the  journalist, philosopher, and critic George Henry Lewes (1817-78), a mar�  ried man, she enjoyed a long and happy, though scandalous, liaison; their  Sunday-aftemoon salons were a brilliant feature of Victorian life.</p><p>Eliot, John (b. 1604, Widford, Hertfordshire, Eng.�d. May 21, 1690,  Roxbury, Massachusetts Bay Colony) English Puritan missionary to the  Indians of Massachusetts Bay Colony. He emigrated to Boston in 1631  and became pastor of a church in nearby Roxbury. Supported by his con�  gregation and fellow ministers, he began a mission to the American Indi�  ans that inspired the creation in 1649 of the first genuine missionary  society (financed chiefly from England). His methods set the pattern of  subsequent Native American missions for almost two centuries. His trans�  lation of the Bible into the Algonquian language was the first Bible printed  in North America.</p><p>Eliot, T(homas) S(tearns) (b. Sept. 26, 1888, St. Louis, Mo.,  U.S.�d. Jan. 4, 1965, London, Eng.) U.S.-British poet, playwright, and  critic. Eliot studied at Harvard University before moving to England in  1914, where he would work as an editor from the early 1920s until his  death. His first important poem, and the first modernist masterpiece in  English, was the radically experimental �Love Song of J. Alfred Prufrock�  (1915). The Waste Land (1922), which expresses with startling power the  disillusionment of the postwar years, made his international reputation.  His first critical volume, The Sacred Wood (1920), introduced concepts  much discussed in later critical theory. He married in 1915; his wife was  mentally unstable, and they separated in 1933. (He married again, hap�  pily, in 1957.) His conversion to Anglicanism in 1927 shaped all his sub�  sequent works. His last great work was Four Quartets (1936-42), four  poems on spiritual renewal and the connections of the personal and his�  torical past and present. Influential later essays include �The Idea of a  Christian Society� (1939) and �Notes Towards the Definition of Culture�  (1948). His play Murder in the Cathedral (1935) is a verse treatment of  St. Thomas Becket�s martyrdom; his other plays, including The Cocktail  Party (1950), are lesser works.

He won the Nobel Prize for Lit�  erature in 1948; from then until his death he achieved public admiration  unequaled by any other 20th-century poet.</p><p>Elis Ve-lis\ modem Ilia \el-'ya\ Ancient Greek region and city-state,  northwestern Peloponnese, Greece. Bounded by Achaea, Arcadia, Messe-  nia, and the Ionian Sea, the region was known for its horse breeding and  was the site of the Olympic Games. As an ally of Athens in the Pelopon�  nesian War, Elis lost much of its territory. Later, by emphasizing the sanc�  tity of the Olympic Games, it regained some land and even some  independence after the Roman occupation of Greece (146 bc), only to  disintegrate with the collapse of the Roman Empire. The modern locality  contains the archaeological site of Olympia, scene of the games.</p><p>Elisabethville See Lubumbashi</p><p>Elisha \i-'li-sh3\ (fl. 9th century bc) Hebrew prophet. As the successor  of Elijah, he was strongly devoted to the Mosaic tradition of Israel and a  potent enemy of all foreign gods and cults. He instigated a revolt against  the ruling house of Israel, the dynasty of Omri, that resulted in the death  of the king and his family. Elisha�s story is told in the Hebrew scriptures  in the books 1 and 2 Kings.</p><p>Elisha ben Abuyah (fl. ad 100) Jewish scholar and apostate. Born  before the destruction of the Second Temple of Jerusalem (ad 70), he  became a respected rabbi but then won notoriety for breaking Jewish laws  and abandoning Judaism. He was well versed in Greek thought, and the  motives for his apostasy may have been devotion to philosophy, mem�  bership in a Gnostic sect, or conversion to Christianity. He was denounced  in the Talmud and was known as Aher (�the Other�) because his apostasy  made his name repugnant.</p><p>Elista \e-'lye-sto,\ English \e-'lis-t9\ formerly (1944-57) Stepnoy  \styip-'noi\ City (pop., 1999 est.: 101,700), capital of Kalmykia republic,  southwestern Russia. It was founded in 1865 and became a city in 1930.  In 1944, when the Kalmyks were exiled by Joseph Stalin for their alleged  collaboration with the Germans, the republic was dissolved and the city  became known as Stepnoy. The name Elista was restored in 1957. Agri�  culture is important, and Elista also is a trade centre for the area.</p><p>Elizabeth (b. Dec. 24, 1837, Munich, Bavaria�d. Sept. 10, 1898,  Geneva, Switz.) Empress consort of Austria (1854-98) and queen of Hun�  gary (1867-98). Regarded as the most beautiful princess in Europe, she  married her cousin, Emperor Francis Joseph, in 1854. She was popular with  her subjects but offended Viennese high society with her impatience with  rigid court etiquette. The Hungarians admired her, especially for her  efforts in bringing about the Compromise of 1867. During a visit to Swit�  zerland she was assassinated by an Italian anarchist.</p><p>Elizabeth or Elizabeth Stuart (b. Aug. 19, 1596, Falkland Palace,  Fifeshire, Scot.�d. Feb. 13, 1662, Westminster, London, Eng.) Titular  queen of Bohemia from 1619. Daughter of the Scottish king James VI  (later James I of England), she came to English royal court in 1606. Noted  for her beauty and charm, she became a favorite subject of the poets. In  1613 she was married to Frederick V, the elector palatine, who became  king of Bohemia (as Frederick I) in 1619. After his defeat by the Catho�  lic League in 1620, the couple went into exile, where Elizabeth spent the  next 40 years. In 1661 her nephew Charles II grudgingly allowed her to  return to England. Her most famous son was Prince Rupert.</p><p>Elizabeth Russian Yelizaveta Petrovna (b. Dec. 18, 1709, Kolo-  menskoye, near' Moscow, Russia�d. Dec. 25, 1761, St. Petersburg)  Empress of Russia (1741-61). Daughter of Peter I and Catherine I, she was  proclaimed empress after staging a coup d�etat and arresting Ivan VI, his  mother, and their chief advisers. She encouraged the development of edu�  cation and art and left control of most state affairs to her advisers and  favorites. Her reign was characterized by court intrigues, a deteriorating  financial situation, and the gentry�s acquisition of privileges at the expense  of the peasantry. However, Russia�s prestige as a major European power  grew. Russia adhered to a pro-Austrian, anti-Prussian foreign policy,  annexed a portion of southern Finland after fighting a war with Sweden,  improved its relations with Britain, and fought Prussia in the Seven Years'  War. Elizabeth was succeeded by her nephew Peter III.</p><p>Elizabeth I (b. Sept. 7, 1533, Greenwich, near London, Eng.�d. March  24, 1603, Richmond, Surrey) Queen of England (1558-1603). Daughter  of Henry VIII and his second wife, Anne Boleyn, she displayed precocious  seriousness as a child and received the rigorous education normally</p><p>reserved for male heirs. Her situation was precarious during the reigns of  her half brother Edward VI and her half sister Mary I. After Sir Thomas  Wyatt�s rebellion in 1554, she was imprisoned but later released. Her  accession to the throne on Mary�s death was greeted with public jubila�  tion. She assembled a core of experienced advisers, including William Cecil  and Francis Walsingham, but she zealously retained her power to make  final decisions. Important events of her reign included the restoration of  England to Protestantism; the execution of Mary, Queen of Scots; and  England�s defeat of the Spanish Armada. She lived under constant threat  of conspiracies by British Catholics. Over time she became known as the  Virgin Queen, wedded to her kingdom. Many important suitors came for�  ward, and she showed signs of romantic attachment to the earl of Leices�  ter, but she remained single, perhaps because she was unwilling to  compromise her power. She had another suitor, the 2nd earl of Essex,  executed in 1601 for treason. Though her later years saw an economic  decline and disastrous military efforts to subdue the Irish, her reign had  already seen England�s emergence as a world power and her presence had  helped unify the nation against foreign enemies. Highly intelligent and  strong-willed, Elizabeth inspired ardent expressions of loyalty, and her  reign saw a brilliant flourishing in the arts, especially literature and music.  After her death, she was succeeded by James I.</p><p>Elizabeth II in full Elizabeth Alexandra Mary (b. April 21,1926,</p><p>London, Eng.) Queen of the United  Kingdom from 1952. She became  heir presumptive when her uncle,  Edward VIII, abdicated and her father  became king as George VI. In 1947  she married her distant cousin Philip,  duke of Edinburgh, with whom she  had four children, including Charles,  prince of Wales. She became queen  on her father�s death in 1952.  Increasingly aware of the modem  role of the monarchy, she favoured  simplicity in court life and took an  informed interest in government  business. In the 1990s the monarchy  was troubled by the highly publi�  cized marital difficulties of two of  the queen�s sons and the death of  Diana, princess of Wales. In 2002 the  queen�s mother and sister died  within two months of each other.</p><p>Elizabeth II, 1985.</p><p>KARSH-CAMERA PRESS/GLOBE PHOTOS</p><p>Elizabeth City (pop., 2000: 120,568), northeastern New Jersey, U.S.  Located on Newark Bay adjacent to Newark, it is connected by bridge to  Staten Island.

The islands were visited in 1602 by the English navigator Bartholomew  Gosnold, who established a short-lived (three-week) colony on the west�  ernmost island of Cuttyhunk 18 years before the arrival of the Mayflower  at Plymouth. Naushon, the largest island, was a British naval base during  the War of 1812. The islands, covering an area of about 14 sq mi (36 sq  km), are mostly privately owned.

She married Louis IV of Thuringia, who died of plague in 1227 en route to  the Sixth Crusade. She then joined the Third Order of St. Francis and  devoted her life to the poor and sick, for whom she built a hospice. As a  young girl, Elizabeth is said to have stolen bread, which she gave to the  poor, and later distributed grain during famines.

Probably the most illustrious age  in the history of English literature, the Elizabethan era saw a flowering  of poetry, produced a golden age of drama, and inspired a wide variety  of splendid prose. The period encompasses the work of Sir Philip Sidney,  Edmund Spenser, Christopher Marlowe, William Shakespeare, and others.  Though some patterns and themes persisted, the tone of most forms of  literary expression, especially drama, darkened rather suddenly around the  start of the 17th century.

Defeat in the Crimean  War, change in public opinion, and the increasing number and violence  of peasant revolts had convinced Alexander of the need for reform. The  final edict was a compromise and fully satisfied no one, particularly the  peasants. It immediately granted personal liberties to the serfs, but the  process by which they were to acquire land was slow, complex, and  expensive. Though it failed to create an economically viable class of  peasant proprietors, its psychological impact was immense.</p><p>Emancipation Proclamation (1863) Edict issued by U.S. Pres.

On taking office,  Lincoln was concerned with preserving the Union and wanted only to  prevent slavery from expanding into the Western territories; but, after the  South seceded, there was no political reason to tolerate slavery. In Sep�  tember 1862 he called on the seceded states to return to the Union or have  their slaves declared free. When no state returned, he issued the procla�  mation on Jan. 1, 1863. The edict had no power in the Confederacy, but  it provided moral inspiration for the North and discouraged European  countries from supporting the South. It also had the practical effect of  permitting recruitment of African Americans for the Union army; by 1865  nearly 180,000 African American soldiers had enlisted. The Thirteenth  Amendment to the Constitution, ratified in 1865, officially abolished sla�  very in the entire country.</p><p>embargo Legal action by a government or group of governments  restricting the departure of vessels or movement of goods from some or  all locations to one or more countries. A trade embargo is a prohibition  on exports to one or more countries. A strategic embargo restricts only the  sale of goods that make a direct and specific contribution to a country�s  military power; similarly, an oil embargo prohibits only the export of oil.  Broad embargoes often allow the export of certain goods (e.g., medicines  or foodstuffs) to continue for humanitarian purposes, and most multilat�  eral embargoes include escape clauses that specify a limited set of con�  ditions under which exporters may be exempt from their prohibitions. An  embargo is a tool of economic warfare that may be employed for a vari�  ety of political purposes, including demonstrating resolve, sending a  political signal, retaliating for another country�s actions, compelling a  country to change its behaviour, deterring it from engaging in undesired  activities, and weakening its military capability.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Embargo Act &#x25BA; Emerson I 617</p><p>Embargo Act Legislation by the U.S. Congress in December 1807 that  closed U.S. ports to all exports and restricted imports from Britain.

The  embargo had little effect in Europe, but it imposed an unpopular restric�  tion on New England merchants and exporters (see Hartford Convention).

In humans, the organism is called an embryo for the first  seven or eight weeks after conception, after which it is called a fetus. In  mammals, the fertilized egg or zygote undergoes cleavage (cell division  without cell growth) to form a hollow ball or blastocyst. During the sec�  ond week following fertilization, gastrulation (cell differentiation and  migration) results in the formation of three tissue types. These three types  of tissue develop into different organ systems: the ectoderm develops into  the skin and nervous system; the mesoderm develops into connective tis�  sues, the circulatory system, muscles, and bones; and the endoderm devel�</p><p>ops into the lining of the digestive system, lungs, and urinary system. In  humans, by about the fourth week, the head and trunk can be distinguished  and the brain, spinal cord, and internal organs begin to develop. By the  fifth week, limbs begin to appear and the embryo is about .33 in. (.8 cm)  long. By the end of eight weeks, the embryo has grown to about 1 in. (2.5  cm) long and all subsequent change is limited primarily to growth and  specialization of existing structures. Any congenital disorders begin in this  stage. See also pregnancy.</p><p>embryology Study of the formation and development of an embryo  and fetus. Before widespread use of the microscope and the advent of  cellular biology in the 19th century, embryology was based on descrip�  tive and comparative studies. From the time of Aristotle it was debated  whether the embryo was a preformed, miniature individual or an undif�  ferentiated form that gradually became specialized. The latter theory was  proved in 1827 when Karl Ernst Baer discovered the mammalian ovum  (egg). The German anatomist Wilhelm Roux (1850-1924), noted for his  pioneering studies on frog eggs (from 1885), became the founder of  experimental embryology.</p><p>'Emeq Yizre'el See Plain of Esdraelon</p><p>emerald Grass-green variety of beryl that is highly valued as a gem�  stone. Its physical properties are those of beryl. Its refractive and disper�  sive powers (i.e., its capacity to deflect light and to break white light into  its component colours) are not high, so cut stones display little brilliancy  or fire (flashes of colour). The colour that gives this gem its value is due  to the presence of small amounts of chromium. The most important pro�  duction of fine quality gem material is from Colombia; emeralds are also  mined in Russia, Australia, South Africa, and Zimbabwe. Synthetic emer�  alds are identical to natural crystals and may rival them in colour and  beauty.</p><p>emergence In the theory of evolution, the rise of a system that cannot be  predicted or explained from antecedent conditions. The British philosopher  of science G.H. Lewes (1817-78) distinguished between resultants and  emergents�phenomena that are predictable from their constituent parts  (e.g., a physical mixture of sand and talcum powder) and those that are not  (e.g., a chemical compound such as salt, which looks nothing like sodium  or chlorine). The evolutionary account of life is a continuous history  marked by stages at which fundamentally new forms have appeared. Each  new mode of life, though grounded in the conditions of the previous stage,  is intelligible only in terms of its own ordering principle. These are thus  cases of emergence. In the philosophy of mind, the primary candidates for  the status of emergent properties are mental states and events.</p><p>Emerson, P(eter) H(enry) (b. May 13, 1856, Cuba�d.

A proponent of photography as  a medium of artistic expression, he published a handbook, Naturalistic  Photography (1889), in which he outlined his aesthetic system (�natural�  ism�), emphasizing that photographs should look like photographs rather  than paintings. The book was so popular that he became known as one  of the world�s leading photographers, and his views influenced much of  20th-century photography.</p><p>Emerson, Ralph Waldo (b.</p><p>May 25, 1803, Boston, Mass.,</p><p>U.S.�d.

He  became internationally famous with his Essays (1841, 1844), including  �Self-Reliance.� Representative Men (1850) consists of biographies of  historical figures. The Conduct of Life (1860), his most mature work,  reveals a developed humanism and a full awareness of human limitations.  His Poems (1847) and May-Day (1867) established his reputation as a  major poet.</p><p>emery Granular rock consisting of a mixture of the mineral corundum  (aluminum oxide, A1 2 0 3 ) and iron oxides such as magnetite (Fe 3 0 4 ) or  hematite (Fe 2 0 3 ). It is a dark, dense substance that looks much like iron  ore. Turkey is the world�s major producer. Long used as an abrasive or  polishing material, particularly in sandpapers, it has largely been replaced  by synthetic materials such as alumina. Its largest application now is as a  nonskid material in floors, stair treads, and pavements.</p><p>emigre nobility \,a-me-'gra,\ English \'e-mi-,gra\ Members of the  French nobility who fled France during the French Revolution. In exile,  mainly in England, many emigres plotted against the Revolutionary gov�  ernment, seeking foreign help to restore the old regime. In response,  Revolutionary leaders in France decreed that those emigres who did not  return by January 1792 were liable to death as traitors, and their property  was confiscated. Napoleon granted the great majority of emigres amnesty  in 1802. During the Bourbon Restoration they were an important force in  French politics.</p><p>Emilia-Romagna Va-'mel-ya-ro-'man-yaX Autonomous region (pop.,  2001 prelim.: 3,960,549), northern Italy. It covers an area of 8,542 sq mi  (22,123 sq km); its chief city and capital is Bologna. Located on the Adri�  atic Sea, Emilia-Romagna includes the Po River to the north and the Apen�  nines to the west and south. It takes its name from the Roman Aemilian  Way, built c. 187 bc. The region formerly comprised the duchies of Parma  and Modena and papal Romagna. Emilia-Romagna became part of the  Kingdom of Italy in 1861; the present political region was created in 1948.  The fertile Emilian Plain in the north makes Emilia-Romagna one of the  leading agricultural regions of Italy. It has a large food-processing indus�  try, and livestock and dairy farming are extensive.</p><p>Emin Pasha \e-'men-pa-'sha\, Mehmed orig. Eduard Schnitzer</p><p>(b. March 28, 1840, Oppeln, Silesia�d. Oct. 23, 1892, Kanema, Congo  Free State) German physician, explorer, and administrator in Egyptian  Sudan. Schnitzer adopted a Turkish name while serving as a medical  officer and administrator in the Ottoman government. In 1876 he joined  with British forces led by Gen. Charles George Gordon at Khartoum. In  1878 he was appointed governor of Equatoria province. During the Mah-  dist movement uprising, the Egyptian government abandoned the Sudan  (1884), and the isolated Emin was rescued by Henry Morton Stanley in  1888. On an expedition to equatorial Africa, he was killed by Arab slave-  traders. Through his scholarly papers and specimen collections, he con�  tributed vastly to the knowledge of African geography, natural history,  ethnology, and languages.</p><p>eminent domain Government power to take private property for pub�  lic use without the owner�s consent. Constitutional provisions in most  countries, including the U.S. (in the 5th Amendment to the Constitution),  require the payment of just compensation to the owner. As a power pecu�  liar to sovereign authority and coupled with a duty to pay compensation,  the concept was developed by such 17th-century natural-law jurists as  Hugo Grotius and Samuel Pufendorf. See also confiscation.</p><p>emir \i-'mir\ In the Muslim Middle East, a military commander, gover�  nor of a province, or high military official. The first leader to call himself  emir was the second caliph, Umar ibn al-Khattab. The title was used by all  his successors until the abolition of the caliphate in 1924. In the 10th cen�  tury the commander of the caliph�s armies at Baghdad held the title. It  was later adopted by the rulers of independent states in central Asia, nota�  bly Bukhara and Afghanistan. The United Arab Emirates, despite their  name, are all ruled by sheikhs.</p><p>Emmett, Daniel Decatur (b. Oct. 29, 1815, Mount Vernon, Ohio,  U.S.�d. June 28, 1904, Mount Vernon) U.S. showman and songwriter.  The son of an Ohio blacksmith, he joined the army at age 17 as a lifer. In  1843 in New York he helped organize the Virginia Minstrels, one of the  earliest minstrel-show troupes. He is credited with writing �Dixie� (1859),  a minstrel �walk-around� (concluding number) that became the Confed�</p><p>eracy�s unofficial national anthem. His other songs include �Old Dan  Tucker� and �Blue-Tail Fly.� He also wrote banjo tunes and music instruc�  tion manuals.</p><p>Emmy award Annual presentation for outstanding achievement in  U.S. television. Its name is taken from the nickname �immy� for the image  orthicon, a television camera tube. The Emmys are presented by the  National Academy of Television Arts and Sciences, founded in 1946,  whose members vote on outstanding programs, actors, directors, and writ�  ers in such categories as drama, comedy, and variety.</p><p>Emory Universify Private university in Atlanta, Georgia, U.S. It was  chartered as a college in 1836 under Methodist auspices; in 1915 it merged  with a school of medicine to become a university. It consists of two  undergraduate colleges (one four-year and one two-year), a graduate  school of arts and sciences, a division of allied health professions, and  schools of law, business, theology, public health, nursing, and medicine.  Research facilities include the Carter Presidential Center, the Yerkes Pri�  mate Center, and a cancer centre.</p><p>emotion Affective aspect of consciousness. The emotions are generally  understood as representing a synthesis of subjective experience, expres�  sive behaviour, and neurochemical activity. Most researchers hold that  they are part of the human evolutionary legacy and serve adaptive ends  by adding to general awareness and the facilitation of social communi�  cation. Some nonhuman animals are also considered to possess emotions,  as first described by Charles Darwin in 1872. An influential early theory  of emotion was that proposed independently by William James and Carl  Georg Lange (1834-1900), who held that emotion was a perception of  internal physiological reactions to external stimuli. Walter B. Cannon  questioned this view and directed attention to the thalamus as a possible  source of emotional content. Later researchers have focused on the brain�  stem structure known as the reticular formation, which serves to integrate  brain activity and may infuse perceptions or actions with emotional  valence. Cognitive psychologists have emphasized the role of comparison,  matching, appraisal, memory, and attribution in the forming of emotions.  All modern theorists agree that emotions influence what people perceive,  learn, and remember, and that they play an important part in personality  development. Cross-cultural studies have shown that, whereas many emo�  tions are universal, their specific content and manner of expression vary  considerably.</p><p>emotivism In metaethics (see ethics), the view that moral judgments do  not function as statements of fact but rather as expressions of the speaker�s  or writer�s feelings. According to the emotivist, when we say �You acted  wrongly in stealing that money,� we are not expressing any fact beyond that  stated by �You stole that money.� It is, however, as if we had stated this fact  with a special tone of abhorrence, for in saying that something is wrong, we  are expressing our feelings of disapproval toward it. Emotivism was  expounded by A. J. Ayer in Language, Truth and Logic (1936) and devel�  oped by Charles Stevenson in Ethics and Language (1945).</p><p>empathy Ability to imagine oneself in another�s place and understand  the other�s feelings, desires, ideas, and actions. The empathic actor or  singer is one who genuinely feels the part he or she is performing. The  spectator of a work of art or the reader of a piece of literature may simi�  larly become involved in what he or she observes or contemplates. The  use of empathy was an important part of the psychological counseling  technique developed by Carl R. Rogers.</p><p>Empedocles Vem-'ped-o-.klezX (b. c. 490, Acragas, Sicily�d. 430 bc,  the Peloponnese) Greek philosopher, statesman, poet, and physiologist. All  that remains of his writings are 500 lines from two poems. He held that all  matter was composed of four basic ingredients: fire, air, water, and earth.  Like Heracleitus, he held that two forces, love and strife, interact to bring  together and separate the four substances. Believing in the transmigration  of souls, he declared that salvation requires abstention from the flesh of  animals, whose souls may once have inhabited human bodies.</p><p>emperor Title of the sovereigns of the ancient Roman empire and, by  derivation, various later European rulers, also applied to certain non-  European monarchs. Caesar Augustus was the first Roman emperor. Byz�  antine emperors ruled at Constantinople until 1453. Charlemagne became  the first of the Western emperors (later Holy Roman emperors) in 800. After  Otto I became emperor in 962, only German kings held the title. In other  parts of Europe, monarchs who ruled multiple kingdoms (e.g., Alfonso VI,  who ruled Leon and Castile) sometimes took the title emperor. Napoleon�s</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>emphysema &#x25BA; enclosure movement I 619</p><p>assumption of the title, as a putative successor of Charlemagne, was a  direct threat to the Habsburg dynasty. Queen Victoria of Britain took the title  empress of India. Non-European peoples whose rulers have been called  emperor include the Chinese, Japanese, Mughals, Incas, and Aztecs.</p><p>emphysema X.em-fo-'ze-mo, .em-fo-'se-moN or pulmonary  emphysema Abnormal distension of the lungs with air, usually asso�  ciated with cigarette smoking and chronic bronchitis. Elastic tissue degen�  erates, severely interfering with exhalation. Capillary walls disappear,  leaving lung tissue dry and pale. The walls of the pulmonary alveoli (see  pulmonary alveolus) break down, so the lung fills with pools of air. Symp�  toms include severe breathlessness, weight loss, bluish skin, chest tight�  ness, and wheezing. In bullous emphysema, the alveoli form large air cysts  that may rupture, causing lung collapse (see atelectasis), or require sur�  gery. Emphysema is irreversible; it normally continues to progress even  after the cessation of smoking and may lead to death.

At a height of 1,250 ft (381 m), it surpassed the Chrysler Building  to become the highest structure in the world (until 1954). It is notable for  its use of the setback.</p><p>Empire Vam-.pir, 'em-.pIiA style Style of furniture and interior decora�  tion that flourished in France during the First Empire (1804-14). It cor�  responds to the Regency style in England. Responding to the desire of  Napoleon for a style inspired by imperial Rome, the architects Charles  Percier (1764-1838) and Pierre Fontaine (1762-1853) decorated his state  rooms with Classical styles of furniture and ornamental motifs, supple�  mented by sphinxes and palm leaves to commemorate his Egyptian cam�  paigns. The style influenced the arts (Jacques- Louis David in painting,  Antonio Canova in sculpture, the Arc de Triomphe in architecture) and  fashion and spread quickly throughout Europe.</p><p>empiricism Either of two closely related philosophical doctrines, one  pertaining to concepts and the other to knowledge. The first doctrine is  that most, if not all, concepts are ultimately derived from experience; the  second is that most, if not all, knowledge derives from experience, in the  sense that appeals to experience are necessarily involved in its justifica�  tion. Neither doctrine implies the other. Several empiricists have allowed  that some knowledge is A priori, or independent of experience, but have  denied that any concepts are. On the other hand, few if any empiricists  have denied the existence of a priori knowledge while maintaining the  existence of a priori concepts. John Locke, George Berkeley, and David Hume  are classical representatives of empiricism.

April 15, 1984, London) British poet and critic. He studied at  Cambridge and later taught in Japan and China. His precocious Seven  Types of Ambiguity (1930), which suggests that uncertainty or overlap of  meanings in the use of a word can be an enrichment of poetry rather than  a fault, had an immense influence on 20th-century criticism; its close  examination of poetic texts helped lay the foundation for New Criticism.  Later works include Some Versions of Pastoral (1935) and The Structure  of Complex Words (1951).</p><p>Ems River River, northwestern Germany. It rises on the southern slope  of the Teutoburg Forest and flows generally northwest and north through  the states of North Rhine-Westphalia and Lower Saxony for 230 mi (371  km) to the North Sea. Its mouth is a wide estuary (the Dollart) bordering  The Netherlands. Between 1892 and 1899 the river was canalized, con�  necting it with the Dortmund-Ems Canal and the Ruhr River in order to  provide a German water link for the Ruhr industrial district.</p><p>Ems Telegram (July 13, 1870) Telegram sent from Ems, Ger., to Otto  von Bismarck and subsequently published by him in an edited version  designed to offend the French government. The telegram reported an  encounter between King William I of Prussia and the French ambassador,  in which William politely refused to promise that no member of his fam�</p><p>ily would seek the Spanish throne, which would constitute a threat to  France. The version published by Bismarck, which made it seem that the  two men had insulted each other, precipitated the Franco-Prussian War.</p><p>emu Ve-.myiiX Ratite of Australia. After the ostrich, the emu is the second-  largest living bird. They stand more  than 5 ft (1.5 m) tall and often weigh  more than 100 lbs (45 kg). The com�  mon emu ( Dromaius novaeholland-  iae, family Dromaiidae), the only  survivor of several forms extermi�  nated by settlers, has a stout body  and long legs. Both sexes are brown�  ish, with a dark-gray head and neck.</p><p>Emus can run up to 30 mph (50 kph);  if cornered, they kick with their large  feet.

Emulsions are stabilized by agents (emul�  sifiers) that (e.g., in the case of soap or detergent molecules) form films  at the droplets� surface or (e.g., in the case of colloidal carbon, bentonite  clay, proteins, or carbohydrate polymers) impart mechanical stability. Less-  stable emulsions eventually separate spontaneously into two liquid lay�  ers; more-stable ones can be destroyed by inactivating the emulsifier, by  freezing, or by heating. Polymerization reactions are often carried out in  emulsions. Many familiar and industrial products are oil-in-water (o/w)  or water-in-oil (w/o) emulsions: milk (o/w), butter (w/o), latex paints  (o/w), floor and glass waxes (o/w), and many cosmetic and personal-care  preparations and medications (either type).</p><p>Enabling Act Law passed by the German Reichstag in 1933 that enabled  Adolf Hitler to assume dictatorial powers. Deputies from the Nazi Party, the  German National People's Party, and the Center Party voted in favor of the  act, which �enabled� Hitler�s government to issue decrees independently  of the Reichstag and the presidency. It gave Hitler a base from which to  carry out the first steps of his National Socialist revolution.</p><p>enamelwork Metal objects decorated with an opaque glaze fused to  the surface by intense heat. The resulting surface is hard and durable and  can be brilliantly colourful. Objects most suitable for enamelwork are  delicate, small (e.g., jewelry, snuffboxes, scent bottles, watches), and  made of copper, brass, bronze, or gold. The best-known processes are  cloisonne and champleve. Enamelwork was produced as early as the 13th  century bc, reached its peak in the Byzantine Empire, and flourished  throughout medieval and Renaissance Europe. In the early 20th century  Carl Faberge produced highly prized objects made of gold, enamel, and  jewels. See also Limoges painted enamel.</p><p>encephalitis Vin-.se-fs-'lI-tosX Inflammation of the brain, most often due  to infection, usually with a virus. One class of encephalitis (including  multiple sclerosis) attacks the myelin sheath that insulates nerve fibres rather  than the neurons themselves. In most cases, symptoms include fever,  headache, lethargy, and coma. Convulsions are most common in infants.  Characteristic neurological signs include uncoordinated, involuntary  movements and localized weakness. The symptoms and a lumbar punc�  ture (to obtain cerebrospinal fluid for analysis) may establish the presence  but not the cause. Treatment usually aims to relieve the symptoms and  ensure quiet rest. Various symptoms may remain after recovery.</p><p>Encke's Comet Veq-kozV Faint comet having the shortest orbital period  (about 3.3 years) of any known, first observed in 1786. It was the second  comet (after Halley's Comet) to have its period determined (1819), by  Johann Franz Encke (1791-1865). Encke also found that the comet�s  period decreases by about 2Vi hours in each revolution and showed that  this effect could not be explained by the planets� gravitational influence.  Its period continues to decrease, though more slowly, and appears to be  related to the effects of outgassing.</p><p>enclosure movement Division or consolidation of communal lands  in Western Europe into the carefully delineated and individually owned  farm plots of modern times.

In England  the movement for enclosure began in the 12th century and proceeded rap�  idly from 1450 to 1640; the process was virtually complete by the end of  the 19th century. In the rest of Europe, enclosure made little progress until  the 19th century. Common rights over arable land have now been largely  eliminated.</p><p>encomienda Ven-.ko-me-'en-doX In colonial Spanish America, a sys�  tem by which the Spanish crown defined the status of the Indian popu�  lation in its colonies. An encomienda consisted of a grant by the crown  of a specified number of Indians living in a particular area. The receiver  {encomenderos) could exact tribute from the Indians and was required to  protect them and instruct them in the Christian faith. The encomienda did  not include a grant of land, but in practice the encomenderos gained con�  trol of Indian lands. Though the original intent was to reduce the abuses  of forced labour, in practice it became a form of enslavement.</p><p>encryption, data See data encryption</p><p>encyclopaedia Reference work that contains information on all  branches of knowledge or that treats a particular branch of knowledge  comprehensively. It is self-contained and explains subjects in greater  detail than a dictionary. It differs from an almanac in that its information is  not dated and not from pedagogical texts in its attempt to be easy to con�  sult and to be readily understood by the layperson. Though generally writ�  ten in the form of many separate articles, encyclopaedias vary greatly in  format and content. The prototype of modern encyclopaedias is usually  acknowledged to be Ephraim Chambers�s Cyclopaedia (1728), and the  first modem encyclopaedia was the French Encyclopedie (1751-65). The  largest general encyclopaedia in English is the Encyclopedia Britannica.</p><p>Encyclopaedia Britannica Oldest and largest English-language gen�  eral encyclopaedia. Its three-volume first edition was published in  1768-71 in Edinburgh, Scot. In subsequent editions it grew in size and  reputation. The most famous editions include the ninth (1875-89), known  as �the scholar�s encyclopaedia,� and the 11th (1910-11), which, with  contributions from more than 1,500 experts of world reputation, was also  the first to divide the traditionally lengthy treatises into more particular�  ized articles. The current edition, the 15th (1974, with a major revision  in 1985), embodied a new structure, dividing the major articles from the  shorter ones. Encyclopaedia Britannica now also appeal's in CD-ROM and  on-line versions. A series of ownership changes led to its purchase by  American publishers in 1901; since the 1940s it has been published in  Chicago.</p><p>Encyclopedie \a n -,se-kl6-pa-'de\ French encyclopedia created in the  18th century by the philosophies; one of the principal works of the Enlight�  enment. Under the full title Encyclopedie, ou dictionnaire raisonne des  sciences, des arts et des metiers (�Encyclopedia, or Classified Dictionary  of Sciences, Arts, and Trades�), it was inspired by the success of E.  Chambers�s British Cyclopaedia; or An Universal Dictionary of Arts and  Sciences (1728). Under the direction of Denis Diderot and initially aided  by Jean Le Rond d'Alembert, 17 volumes were published between 1751 and  1765; other volumes were added later for a total of 35. Though opposed  by conservative ecclesiastics and government officials and subjected to  censorship, the Encyclopedie attracted articles from many important  thinkers of the time, including Jean-Jacques Rousseau, Voltaire, and Denis  Diderot, who were called �Encyclopedists.� In its skepticism, its empha�  sis on scientific determinism, and its criticism of the abuses perpetrated  by contemporary legal, judicial, and clerical institutions, the work had  widespread influence as an expression of progressive thought prior to the  French Revolution.</p><p>endangered species Any species of plant or animal threatened with  extinction. International and national agencies work to maintain lists of  endangered species, to protect and preserve natural habitats, and to pro�  mote programs for recovery and reestablishment of these species. The  Species Survival Commission of the International Union for Conserva�  tion of Nature and Natural Resources (IUCN) publishes information  online about endangered species worldwide as the Red List of Threatened  Species. Separate books for animal and plant species are also published.  In the United States, the Fish and Wildlife Service is responsible for the  conservation and management of fish and wildlife, including endangered  species, and their habitats. Its list now consists of about 1,200 domestic  species of endangered or threatened animals and plants, and some 200  recovery programs are in effect.</p><p>endive Yen-.dlv, ,an-'dev\ Edible annual leafy plant ( Cichorium endi-  via) of the composite family. It is variously believed to have originated in  Egypt and Indonesia, and it has been cultivated in Europe since the 16th  century. The many kinds of endive form two groups: the curly or narrow�  leaved endive (C. endivia, variety crispa ) and the Batavian, or broad�  leaved, endive (C. endivia , variety latifolia ), which is also called escarole.  The former is used mostly for salads, the latter for cooking.</p><p>endocarditis N.en-do-kar-'dI-tosN Inflammation of the heart lining  (endocardium), in association with a noninfectious disease (e.g., systemic  lupus erythematosus) or caused by infection, usually at the heart valves.  Severe bacterial infection causes an acute form with fever, sweating,  chills, joint pain and swelling, and embolisms. Subacute endocarditis usu�  ally comes from bacteria that do not ordinarily cause disease. Bacterial  endocarditis is usually treated with long-term antibiotics. In nonbacterial  thrombotic endocarditis, blood clots form along heart valve edges.</p><p>endocrine Ven-do-kronN system Group of ductless glands that secrete  hormones necessary for normal growth and development, reproduction,  and homeostasis. The major endocrine glands are the hypothalamus, pitu�  itary, PINEAL, THYROID, PARATHYROIDS, ADRENALS, islets of LANGERHANS in the PAN�  CREAS, ovaries, and testes. Secretion is regulated either by regulators in a  gland that detect high or low levels of a chemical and inhibit or stimu�  late secretion or by a complex mechanism involving the hypothalamus  and the pituitary. Tumours that produce hormones can throw off this bal�  ance. Diseases of the endocrine system result from over- or underproduc�  tion of a hormone or an abnormal response to a hormone. See illustration  opposite on following page.</p><p>endocrinology Yen-do-kri-'nal-o-jeX Medical discipline dealing with  regulation of body functions by hormones and other biochemicals and  treatment of endocrine system imbalances. In 1841 Friedrich Gustav Henle  first recognized �ductless glands,� which secrete products directly into the  bloodstream. The field was essentially established in the early 20th cen�  tury, when Ernest H. Starling, who introduced the term hormone , proposed  that chemical and nervous regulation of physiological processes were  linked. Endocrine therapy is based on replacing deficient hormones with  purified extracts. Nuclear technology has led to new treatments; use of  radioactive iodine for hyperthyroidism greatly reduced the need for thy�  roid gland surgery. The detection of minute amounts of hormone with  radioimmunoassays (see radiology) permits early diagnosis and treatment  of endocrine disorders.</p><p>endogamy See exogamy and endogamy</p><p>endometriosis V.en-do-.me-tre-'o-sosV Disorder of the female repro�  ductive system in which endometrium (uterine lining) grows in an abnor�  mal location because some endometrial fragments traverse the fallopian  tubes into the abdominal cavity and become embedded on structures there,  usually the ovaries, rather than exiting the uterus via the vagina (during  menstruation). Symptoms include pain on menstruation, sexual inter�  course, defecation, and/or urination; heavy menstrual flow; blood in the  urine; and infertility. Diagnosis is best made by laparoscopy. Treatment  includes surgery and hormones to suppress ovulation for six to nine  months.</p><p>endoplasmic reticulum Yen-do-'plaz-mik-ro-'tik-yo-bmX (ER)  Membrane system within the cytoplasm of a eukaryotic cell (see eukary�  ote), important in the synthesis of proteins and lipids. The ER usually  makes up more than half the membrane of the cell and is continuous with  the outer membrane of the nuclear envelope (see nucleus). There are two  distinct regions of ER: the rough ER, or RER (so called because of the  protein-synthesizing ribosomes attached to it), and the smooth ER (SER),  which is not associated with ribosomes and is involved in the synthesis  of lipids and the detoxification of some toxic chemicals.</p><p>endorphin \en-'dor-f3n\ Any of a group of proteins occurring in the  brain and having pain-relieving properties typical of opium and related  opiates. Discovered in the 1970s, they include enkephalin, beta-  endorphin, and dynorphin. Each is distributed in characteristic patterns  throughout the nervous system. Endorphins are released in response to  pain or sustained exertion (causing, e.g., the �runner�s high�). They are  also believed to have a role in appetite control, release of pituitary sex hor�  mones, and shock. There is strong evidence that they are connected with  �pleasure centres� in the brain, and they seem to be activated by acupunc�  ture. Knowledge of their behaviour has implications for treating addic�  tions and chronic pain.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>endoscopy &#x25BA; Engels I 621</p><p>hypothalamus  - pineal gland  pituitary gland</p><p>-thyroid gland</p><p>parathyroid glands  (behind thyroid)</p><p>adrenal glands</p><p>-islets of</p><p>Langerhans  (in pancreas)</p><p>ovary (in female)</p><p>testis (in male)</p><p>Major glands of the human endocrine system. The hypothalamus stimulates the pitu�  itary gland and influences food intake, weight regulation, fluid intake and balance,  thirst, body heat, and the sleep cycle. Pituitary hormones stimulate growth, egg and  sperm development, milk secretion, and release of hormones by other glands. The  pineal gland may play a significant role in sexual maturation and the circadian  rhythm. Thyroid hormones regulate the metabolic rate of tissues, stimulate the con�  traction of heart muscle, and are necessary for normal growth and brain develop�  ment before birth and during infancy. Parathyroid hormone regulates calcium,  phosphorus, and magnesium levels. The adrenal glands regulate salt and water  retention, some reactions of the immune system, and blood pressure.

Endoscopes include the upper gastrointestinal endo�  scope (for the esophagus, stomach, and duodenum), the colonoscope (for  the colon), and the bronchoscope (for the bronchial tubes). With fibre optics,  much more maneuverable instruments can reach formerly inaccessible  sites, while causing much less discomfort.

The  endotherms include the birds and mammals. If heat loss exceeds heat gen�  eration, metabolism increases to make up the loss or the animal shivers  to raise its body temperature. If heat generation exceeds the heat loss,  mechanisms such as panting or perspiring increase heat loss. Unlike ecto-  therms, endotherms can be active and survive at quite low external tem�  peratures, but because they must produce heat continuously, they require  high quantities of �fuel� (i.e., food).</p><p>Energia also called RKK Energia formerly OKB-1 Russian aero�  space company that is a major producer of spacecraft, rockets, and mis�  siles. Energia originated in 1946 as a department within a Soviet institute</p><p>conducting work on long-range missiles. Ten years later, under Sergey  Korolyov, it became the independent design bureau OKB-1. In the 1950s  it developed the R-7 (SS-6), the world�s first inter-continental ballistic  missile; a modified R-7 placed the first artificial satellite into orbit (see  Sputnik). OKB-1 was responsible for the U.S.S.R.�s commanding early  lead in the �space race,� although it failed in its secret project to beat the  U.S. to a manned Moon landing. In 1974 the conglomerate NPO Energia  was created with OKB-1 at its center. A main focus for the company was  the development and operation of space stations (see Salyut, Mir). In the  early 1990s Energia became the main contractor for the Russian portion  of the International Space Station (it provided the station�s Zvezda habi�  tat and control module), but its role was later reduced. In 1994 it was  renamed RKK Energia and partially privatized. After the dissolution of  the Soviet Union in 1991, Energia partnered with multinational satellite  launching services, to which it provided its Block DM upper stage for  boosting payloads to geostationary orbit.</p><p>energy Capacity for doing work. Energy exists in various forms�  including kinetic, potential, thermal, chemical, electrical (see electricity), and  nuclear �and can be converted from one form to another. For example,  fuel-burning heat engines convert chemical energy to thermal energy;  batteries convert chemical energy to electrical energy. Though energy may  be converted from one form to another, it may not be created or destroyed;  that is, total energy in a closed system remains constant. All forms of  energy are associated with motion. A rolling ball has kinetic energy, for  instance, whereas a ball lifted above the ground has potential energy, as  it has the potential to move if released. Heat and work involve the trans�  fer of energy; heat transferred may become thermal energy. See also acti�  vation ENERGY, BINDING ENERGY, IONIZATION ENERGY, MECHANICAL ENERGY, SOLAR  ENERGY, ZERO-POINT ENERGY.</p><p>energy, conservation of Principle of physics according to which  the energy of interacting bodies or particles in a closed system remains  constant, though it may take different forms (e.g., kinetic energy, potential  energy, thermal energy, energy in an electric current, or energy stored in an  electric field, in a magnetic field, or in chemical bonds [see bonding]). With  the advent of relativity physics in 1905, mass was recognized as equiva�  lent to energy. When accounting for a system of high-speed particles  whose mass increases as a consequence of their speed, the laws of con�  servation of energy and conservation of mass become one conservation  law. See also Hermann von Helmholtz.</p><p>energy, equipartition of Law of statistical mechanics stating that, in  a system in thermal equilibrium, on average, an equal amount of energy is  associated with each independent energy state. It states specifically that a  system of particles in equilibrium at absolute temperature T will have an  average energy of VikT, where k is the Boltzmann constant, associated  with each degree of freedom. For example, an atom of a gas has three  degrees of freedom (its three position coordinates); therefore, it will have  an average total energy of VikT.</p><p>Engelbart, Douglas (b.

Son of a factory owner, he eventually became a successful  businessman himself, never allowing his criticism of capitalism to inter�  fere with the profitable operations of his firm. As a young man, he devel�  oped an interest in the philosophy of G.W.F. Hegel as expounded by the  Young Hegelians, and he became persuaded that the logical consequence  of Hegelianism and dialectic was communism. In 1844 he published The  Condition of the Working Class in England. With Karl Marx, whom he  met in Cologne, he formed a permanent partnership to promote the social�  ist movement. After persuading the second Communist Congress to adopt  their views, the two men were authorized to draft the Communist Mani�  festo (1848).

Engineering  is based principally on physics, chemistry, and mathematics and their  extensions into materials science, solid and fluid mechanics, thermodynam�  ics, transfer and rate processes, and systems analysis. A great body of spe�  cial knowledge is associated with engineering; preparation for  professional practice involves extensive training in the application of that  knowledge. Engineers employ two types of natural resources, materials  and energy. Materials acquire uses that reflect their properties: their  strength, ease of fabrication, lightness, or durability; their ability to insu�  late or conduct; and their chemical, electrical, or acoustical properties.  Important sources of energy include fossil fuels (coal, petroleum, gas),  wind, sunlight, falling water, and nuclear fission.

Area: 50,351 sq mi (130,410 sq km). Population (2001): 49,138,831. It  is the largest constituent unit of the United Kingdom of Great Britain and  Northern Ireland. England is often erroneously considered synonymous  with the island of Great Britain and even with the entire kingdom. Despite  the political, economic, and cultural legacy that has perpetuated its name,  however, England no longer officially exists as a country and enjoys no  separate political status within the United Kingdom. It is a land of low  hills and plateaus, with a 2,000-mi (3,200-km) coastline. A substantial  upland, the Pennines, divides northern England; the Cheviot Hills define  the Scottish border. In the southwest lie the Cotswold Hills and the pla�  teau regions of Exmoor and Dartmoor; in the southeast lie the Downs and  in the south the Salisbury Plain. English weather is diverse, with a gen�  erally mild but erratic maritime climate. England is divided into eight  geographic regions, often referred to as the standard regions of England;  they do not serve any administrative function. The South East, centred on  London, is an economically dominant area. It contains an extensive range  of manufacturing and science-based industries and commercial endeav�  ours. The West Midlands, in west-central England, is a diversified manu�  facturing region that centres on Birmingham. The region also includes the  Shakespeare country, centred on Stratford-upon-Avon. The East Mid�  lands, in east-central England, is also a manufacturing region and con�  tains some of England�s best farmland. East Anglia is the easternmost part  of England. It is mainly an agricultural region, but high-technology indus�  tries have developed there. Manchester and Liverpool are the chief indus�  trial cities of the North West; the region has long been known for textile  production, but that has rapidly given way to diversified manufacturing.  The Humberside region lies to the east and is noted for textiles and steel�  making, though its economy has become more diversified and there is  extensive farmland. The North region extends north to the Scottish bor�  der. It includes the celebrated Lake District and is a centre of engineering  and pharmaceutical manufacture. The South West region, which includes  Cornwall, has a growing tourist industry, and some areas are becoming  industrialized. England is especially noted for its long and rich literary  tradition, as well as for its architecture, painting, theatres, museums, and  universities (see University of Oxford; University of Cambridge). It also  played an integral role in rock music (see British Invasion).</p><p>England, Church of English national church and the mother church  of the Anglican Communion. Christianity was brought to England in the</p><p>2nd century, and though nearly destroyed by the Anglo-Saxon invasions,  it was reestablished after the mission of St. Augustine of Canterbury in  597. Medieval conflicts between church and state culminated in Henry  VIII �s break with Roman Catholicism in the Reformation. When the pope  refused to annul Henry�s marriage to Catherine of Aragon, the king issued  the Act of Supremacy (1534), which declared the English monarch to be  head of the Church of England. Under Henry�s successor, Edward VI, more  Protestant reforms were instituted. After a five-year Catholic reaction  under Mary I, Elizabeth I ascended the throne (1558), and the Church of  England was reestablished. The Book of Common Prayer (1549) and the  Thirty-nine Articles (1571) became the standards for liturgy and doctrine.  The rise of Puritanism in the 17th century led to the English Civil Wars;  during the Commonwealth the Church of England was suppressed, but it  was reestablished in 1660. The evangelical movement in the 18th century  emphasized the church�s Protestant heritage, while the Oxford movement  in the 19th century emphasized its Roman Catholic heritage. The Church  of England has maintained an episcopal form of government, and its  leader is the archbishop of Canterbury. In 1992 the church voted to ordain  women as priests. In the U.S., the Protestant Episcopal Church is descended  from and remains associated with the Church of England.</p><p>Engle, Robert F. (b. November 1942, Syracuse, N.Y., U.S.) U.S.  economist. After graduating from Cornell University (M.S., 1966; Ph.D.,  1969), Engle taught at such universities as the Massachusetts Institute of  Technology and the University of California at San Diego and held asso�  ciate editorships on several academic journals. In the 1970s and �80s he  developed improved mathematical techniques for the evaluation and  more-accurate forecasting of risk, which enabled researchers to test if and  how volatility in one period was related to volatility in another period.  His work had particular relevance in financial market analysis and enabled  economists to make more-accurate forecasts. In 2003 he shared the Nobel  Prize for Economics with Clive WJ. Granger.</p><p>English Channel or the Channel French La Manche \la-'maush\  ("The Sleeve") Strait between southern England and northern France.  It connects the Atlantic Ocean with the North Sea through the Strait of  Dover. The French name, La Manche (�The Sleeve�), is a reference to its  shape, which gradually narrows from about 112 mi (180 km) in the west  to only 21 mi (34 km) in the east, between Dover, Eng., and Calais, France.  Historically both a route for and a barrier to invaders of Britain, it devel�  oped into one of the world�s busiest sea routes for oil tankers and ore  carriers. The Channel Tunnel, completed in 1994, provides a land route  between Paris and London.</p><p>English Civil Wars (1642-51) Armed conflict in the British Isles  between Parliamentarians and supporters of the monarchy (Royalists).  Tension between Charles I and the House of Commons had been building  for some time, and after his unsuccessful attempt to arrest five members  of Parliament, both sides prepared for war. The first phase of the wars  (1642-46) was initially characterized by inconclusive encounters, but vic�  tories by Parliamentarian forces under Oliver Cromwell at the Battles of  Marston Moor and Naseby turned the tide. In 1646 the Royalist forces  were disbanded. In 1647 Charles I negotiated with a Scottish group for  assistance, starting the second phase of the wars, a series of Royalist  rebellions, and a Scottish invasion. All were defeated, and Charles I was  executed in 1649. The fighting continued, and Royalist forces under  Charles II invaded England in 1651. Parliamentary forces defeated the  Royalists at Worcester in 1651 and Charles II fled abroad, effectively end�  ing the civil wars. The wars� political consequence was the establishment  of the Commonwealth and Protectorate. See also New Model Army, Sol�  emn League and Covenant.</p><p>English East India Co.

English relies mainly on word order (usually subject-verb-  object) to indicate relationships between words (see syntax). Written in the  Latin alphabet, it is most closely related to Frisian, German, and Dutch. Its  history began with the migration of the Jutes, Angles, and Saxons from  Germany and Denmark to Britain in the 5th and 6th centuries. The Norman  Conquest of 1066 brought many French words into English. Greek and  Latin words began to enter it in the 15th century, and Modern English is  usually dated from 1500. English easily borrows words from other lan�  guages and has coined many new words to reflect advances in technology.</p><p>English school Dominant school in painting in England from the 18th  century to c. 1850. From 1730 to 1750 two distinctive British forms of  painting were perfected by William Hogarth: genre scenes depicting the  �modem moral subject,� and the small-scale group portrait, or �conver�  sation piece.� Full-scale portraiture was popularized by Joshua Reynolds  and Thomas Gainsborough; the landscape tradition was founded by Rich�  ard Wilson; and historical painting was practiced by two American-born  painters, Benjamin West and John Singleton Copley. The flowering of  English Romantic art was embodied in the landscapes of J.M.W. Turner  and John Constable.

Wood engraving  derives from the woodcut, but the use of the hard, smooth boxwood, cut  with the burin commonly used by the copper-plate engraver, produces a  finer, more detailed image. By contrast with engraving from metal plates,  the printing of wood engravings is done from the surface of the plate or  block; the parts that are not to be printed are cut away.

He aids Gil�  gamesh in killing the divine bull sent by the goddess Ishtar to destroy  them. The gods then kill Enkidu in revenge, prompting Gilgamesh to  search for immortality.</p><p>Enlightenment European intellectual movement of the 17th�18th cen�  tury in which ideas concerning God, reason, nature, and man were blended  into a worldview that inspired revolutionary developments in art, philoso�  phy, and politics. Central to Enlightenment thought were the use and cel�  ebration of reason. For Enlightenment thinkers, received authority,  whether in science or religion, was to be subject to the investigation of  unfettered minds. In the sciences and mathematics, the logics of induc�  tion and deduction made possible the creation of a sweeping new cos�  mology. The search for a rational religion led to Deism; the more radical  products of the application of reason to religion were skepticism, atheism,  and materialism. The Enlightenment produced modern secularized theo�  ries of psychology and ethics by men such as John Locke and Thomas  Hobbes, and it also gave rise to radical political theories. Locke, Jeremy  Bentham, J.-J. Rousseau, Montesquieu, Voltaire, and Thomas Jefferson all  contributed to an evolving critique of the authoritarian state and to sketch�  ing the outline of a higher form of social organization based on natural  rights. One of the Enlightenment�s enduring legacies is the belief that  human history is a record of general progress.</p><p>Ennin Ven-,nen\ (b. 794, Tsuga district, Shimotsuke province, Japan�d.

He spent nine years studying Buddhism  in China, returning home in ad 847 with 559 volumes of Chinese Bud�  dhist texts and a system of musical notation for religious chants that is  still used in Japan. He introduced to Japanese Buddhism the practice of  chanting the name of Amida ( Amitabha) as a route to rebirth in Amida�s  paradise. He also established Tendai esotericism.

In 1883 he  joined a group known as Les Vingt (�The Twenty�) and began depicting  skeletons, phantoms, masks, and other images of grotesque fantasy as  social commentary. His work from this period has often been described  as Symbolist. His Entry of Christ into Brussels (1888), painted in smeared,  garish colours, provoked outrage. Continuing negative criticism plunged  him ever deeper into cynicism until he finally became a recluse. The exhi�  bition of Entry of Christ in 1929 led to his being ennobled by King Albert  of Belgium.

It granted freedom of action to Britain in Egypt and to France in Morocco  and resolved several other imperial disputes. The agreement reduced the  virtual isolation of each country and was consequently upsetting to Ger�  many, which had benefited from their antagonism. The Entente paved the  way for Anglo-French diplomatic cooperation against Germany before  World War I and for later military alliances.</p><p>enthalpy Ven-thol-peV Sum of the internal energy E and the product of  the pressure P and volume V of a thermodynamic system (see thermody�  namics). So, enthalpy H = E + PV. Its value is determined by the tem�  perature, pressure, and composition of the system at any given time.  According to the law of conservation of energy (see conservation law),  the change in internal energy is equal to the heat transferred to the sys�  tem minus the work done by the system. If the only work done is a change  of volume at constant pressure, the enthalpy change is exactly equal to  the heat transferred to the system.</p><p>entomology Branch of zoology dealing with the scientific study of  INSECTS, including their taxonomy, morphology, physiology, and ecology.  Applied aspects of entomology, such as the harmful and beneficial impact  of insects on humans, are also studied.</p><p>entropy \'en-tro-pe\ Measure of a system�s energy that is unavailable  for work, or of the degree of a system�s disorder. When heat is added to  a system held at constant temperature, the change in entropy is related to  the change in energy, the pressure, the temperature, and the change in vol�  ume. Its magnitude varies from zero to the total amount of energy in a  system. The concept, first proposed in 1850 by the German physicist  Rudolf Clausius (1822-1888), is sometimes presented as the second law  of thermodynamics, which states that entropy increases during irreversible  processes such as spontaneous mixing of hot and cold gases, uncontrolled  expansion of a gas into a vacuum, and combustion of fuel. In popular,  nontechnical use, entropy is regarded as a measure of the chaos or ran�  domness of a system.</p><p>enuresis \,en-yu-'re-s3s\ Repeated urination into bedding or clothing,  usually at night, in a normal child old enough to have completed toilet  training. Enuresis may be voluntary or involuntary. It may run in fami�  lies. Stressful life events, poor toilet training, and chronic social disad�  vantage increase its likelihood. It usually resolves with time. Treatment  includes family education, reassurance, and behaviour therapy. An alarm  to wake the child when urination begins has proved highly effective but  takes time to achieve complete success.

He later served as governor of  BanghazI, Libya (1912), chief of staff of the Ottoman army in the Sec�  ond Balkan War (1913), and minister of war during World War I (1914�  18). A rival of Mustafa Kemal AtatOrk in the postwar period, he  unsuccessfully sought Soviet help to overthrow him (1920). The Soviets  permitted him to help organize the Turkic and Muslim Central Asian  republics, but he joined Basmachi rebels against the Soviet Union and  was killed fighting the Red Army.</p><p>environmental geology Scientific field concerned with applying the  findings of geologic research to the problems of land use and civil engi�  neering.

It was  established by Pres. Richard Nixon (1970) to supersede a welter of con�  fusing and ineffective state environmental laws. Its early accomplishments  include banning the use of DDT (1972), setting deadlines for the removal  of lead from gasoline (1973), establishing health standards for drinking  water (1974), and monitoring fuel efficiency in automobiles (1975). The  EPA�s enforcement was in large part responsible for a decline of one-  third to one-half in most air-pollution emissions in the U.S. from 1970 to  1990, and during the 1980s the pollution standards index improved by  half in major cities; water quality and waste disposal also improved sig�  nificantly. The EPA also oversees the cleanup of abandoned waste sites  through Superfund. Its existence has resulted in heightened awareness and  concern for the environment worldwide.</p><p>environmental sculpture Art form, developed in the 20th century,  that involves or encompasses the spectator. The environmental sculptor  can use any medium, from mud and stone to light and sound. Indoor envi�  ronmental works often incorporate sculptural figures in detailed settings  in gallery or museum spaces. Outdoor works in natural or urban settings  include �earthworks� (large-scale alterations of the Earth�s surface  effected by earth-moving equipment) such as Robert Smithson�s Spiral  Jetty (1970), a rock-and-dirt spiral 1,500 feet long in the Great Salt Lake.  The wrapped buildings of Christo are notable urban environmental works.</p><p>environmentalism Advocacy of the preservation or improvement of  the natural environment, especially the social and political movement to  control environmental pollution. Other specific goals of environmental�  ism include control of human population growth, conservation of natural  resources, restriction of the negative effects of modem technology, and  the adoption of environmentally benign forms of political and economic  organization. Environmental advocacy at the international level by non�  governmental organizations and some states has resulted in treaties, con�  ventions, and other instruments of environmental law addressing  problems such as global warming, the depletion of the ozone layer, and the  danger of transboundary pollution from nuclear accidents. Influential U.S.  and British environmentalists have included Thomas Robert Malthus, John  Muir, Rachel Carson, Barry Commoner, Paul R. Ehrlich, and Edward O.  Wilson. In the social sciences, the term refers to any theory that empha�  sizes the importance of environmental factors in the development of cul�  ture and society.</p><p>enzyme Substance that acts as a catalyst in living organisms, regulat�  ing the rate at which life�s chemical reactions proceed without being altered  in the process. Enzymes reduce the activation energy needed to start these  reactions; without them, most such reactions would not take place at a</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Eocene &#x25BA; Epicureanism I 625</p><p>useful rate. Because enzymes are not consumed, only tiny amounts of  them are needed. Enzymes catalyze all aspects of cell metabolism, includ�  ing the digestion of food, in which large nutrient molecules (including  proteins, carbohydrates, and fats) are broken down into smaller molecules;  the conservation and transformation of chemical energy; and the con�  struction of cellular materials and components. Almost all enzymes are  proteins; many depend on a nonprotein cofactor, either a loosely associ�  ated organic compound (e.g., a vitamin; see coenzyme) or a tightly bound  metal ion (e.g., iron, zinc) or organic (often metal-containing) group. The  enzyme-cofactor combination provides an active configuration, usually  including an active site into which the substance (substrate) involved in  the reaction can fit. Many enzymes are specific to one substrate. If a com�  peting molecule blocks the active site or changes its shape, the enzyme�s  activity is inhibited. If the enzyme�s configuration is destroyed (see dena-  turation), its activity is lost. Enzymes are classified by the type of reac�  tion they catalyze: (1) oxidation-reduction, (2) transfer of a chemical  group, (3) hydrolysis, (4) removal or addition of a chemical group, (5)  isomerization (see isomer; isomerism), and (6) binding together of substrate  units (polymerization). Most enzyme names end in -ase. Enzymes are chiral  catalysts, producing mostly or only one of the possible stereoisomeric  products (see optical activity). The fermentation of wine, leavening of  bread, curdling of milk into cheese, and brewing of beer are all enzymatic  reactions. The uses of enzymes in medicine include killing disease-  causing microorganisms, promoting wound healing, and diagnosing cer�  tain diseases.</p><p>Eocene \'e-9-,sen\ Epoch Major division of the Tertiary Period, from  54.8 to 33.7 million years ago. It follows the Paleocene Epoch and pre�  cedes the Oligocene Epoch. The name, derived from the Greek eos  (�dawn�), refers to the dawn of recent life; during the Eocene, all the  major divisions, or orders, of modem mammals appeared, as well as many  essentially modern bird orders. Climates were warm and humid. Temper�  ate and subtropical forests were widespread, but grasslands were limited.</p><p>Eochaid Ollathair See Dagda</p><p>Eohippus \,e-6-'hi-p3s\ Former name of a genus of ancestral horses,  commonly called dawn horses, that flourished in North America during  the Early Eocene Epoch (54.8^19 million years ago). It is now classified  with European species in the genus Hyracotherium. Eohippus stood 1-2  ft (30-60 cm) high at the shoulders and was adapted to running, with hind  legs longer than the forelegs. The body was lightly constructed, with  slender legs and elongated feet that were functionally three-toed (though  the front feet had four toes). The skull varied from shortened (primitive)  to relatively long (more horselike).</p><p>Eolie \a-'6-le-,a\ Islands or Lipari \'li-pa-re\ Islands Volcanic island  group, Tyrrhenian Sea, in the west-central Mediterranean Sea. Located  off the northern coast of Sicily, the seven major islands and several islets  have a total land area of 34 sq mi (88 sq km). The major islands are Ali-  cudi, Eilcudi, Lipari, Panarea, Salina, Stromboli, and Vulcano. Vulcano  and Stromboli are active volcanoes. The Greeks believed the islands to  be the home of the god Aeolus, king of the winds. They have been inhab�  ited since the Neolithic Period and were held successively by the Greeks,  Carthaginians, Romans, Saracens, Normans, Angevins, and Aragonese.</p><p>eon Long span of geologic time. In formal usage, eons are the longest  portions of geologic time (eras are the second-longest). Three eons are  recognized: the Phanerozoic Eon (dating from the present back to the  beginning of the Cambrian Period), the Proterozoic Eon, and the Archean  Eon. Less formally, eon often refers to a span of one billion years.</p><p>eon (Gnosticism) See aeon</p><p>EPA See Environmental Protection Agency</p><p>Epaminondas U-.pam-s-'nan-dosV (b. c. 410, Thebes�d. 362 bc, Man-  tineia) Theban statesman, tactician, and leader. He defeated the Spartans  at Leuctra in 371, using a new strategy that attacked the opponent�s stron�  gest point first with overwhelming power, and made Thebes the most  powerful state in Greece. He led four more successful expeditions into  the Peloponnese. In 370-369 he freed the Messenian helots from Spartan  enslavement. In 362, at the head of a large allied force, he defeated Sparta,  Athens, and their allies at Mantineia, but he was mortally wounded.</p><p>ephemeris Vi-'fe-ms-rosX Table of the positions of celestial bodies at  regular intervals, often with supplementary information. Constructed as  early as the 4th century bc, ephemerides are still essential to astronomers</p><p>and navigators. Modern ephemerides are calculated, with heavy comput�  ing and careful checking, after a mathematical description of a heavenly  body�s observed motion has been evolved. Various national ephemerides  are published regularly; the U.S. ephemeris, first published in 1852,  became the best and is now published jointly with the U.K. as The Astro�  nomical Almanac.</p><p>Ephesus Ve-f3-s3s\ Ancient Ionian Greek city; its ruins lie near the  modern village of Selguk in western Turkey. It was situated south of the  Cayster River and was the site of the Temple of Artemis. Traditionally  founded by the Carians, it was one of the 12 Ionian Cities and was  involved in the Persian and Peloponnesian wars. It was taken by Alexander  the Great c. 334 bc and prospered throughout the Hellenistic period. It  passed to Rome in 133 bc and under the emperor Augustus became the  capital of the Roman province of Asia. It was an early seat of Christian�  ity, which was visited by St. Paul; the Letter of Paul to the Ephesians was  directed to the residents of the city. The Goths destroyed the city and  temple in ad 262; neither ever recovered. There are extensively excavated  ruins at the modern site.</p><p>ephor Ve-far, 'e-,f6r\ (Greek ephoros ) Title of the five highest Spartan  magistrates. With the two kings of Sparta they formed the state�s execu�  tive wing. The list of ephors dates back to 754 bc. Every male citizen was  eligible for election to the ephorate, which conducted meetings of the GER-  ousia and apella and executed their decrees. The ephors� extensive police  powers allowed them to declare war on the helots annually, with legal  license to attack and kill them if necessary. In an emergency they could  even arrest and try a king.</p><p>epic Long, narrative poem in an elevated style that celebrates heroic  achievement and treats themes of historical, national, religious, or leg�  endary significance. Primary (or traditional) epics are shaped from the  legends and traditions of a heroic age and are part of oral tradition; sec�  ondary (or literary) epics are written down from the beginning, and their  poets adapt aspects of traditional epics. The poems of Homer are usually  regarded as the first important epics and the main source of epic conven�  tions in western Europe. These conventions include the centrality of a  hero, sometimes semidivine; an extensive, perhaps cosmic, setting; heroic  battle; extended journeying; and the involvement of supernatural beings.</p><p>epic theatre Dramatic form developed in Germany after World War I  by Bertolt Brecht and others, intended to provoke rational thought rather  than to create illusion. It presents loosely connected scenes often inter�  rupted by direct addresses to the audience providing analysis, argument,  or documentation. Brecht�s goal was to use alienating or distancing effects  to block the emotional responses of the audience members and force them  to think objectively about the play. Actors were instructed to keep a dis�  tance between themselves and the characters they portrayed and to empha�  size external actions rather than emotions.</p><p>epicentre Point on the surface of the Earth that is directly above the  source (or focus) of an earthquake. There the effects of the earthquake  usually are most severe. See also seismology.</p><p>Epictetus \,ep-ik-'tet-3s\ (b. c. ad 55�d. c. 135) Greek philosopher  associated with Stoicism. His original name is not known; epiktetos means  �acquired.� He is not known to have written anything, but his teachings  were transmitted by his pupil Arrian (d. c. ad 180) in two works, the Dis�  courses and the Encheiridion. True education, Epictetus believed, con�  sists in recognizing that the only thing that belongs to an individual fully  is his will. Humans are not responsible for the ideas that present them�  selves to their consciousness, though they are wholly responsible for how  they react to them.</p><p>Epicureanism V.e-pi-kyu-'re-o-.ni-zom, .e-pi-'kyur-e-o-.ni-zomX Meta�  physical and ethical doctrines taught by Epicurus. In metaphysics, the basic  concepts of Epicureanism were atomism; mechanical causality limited by  the spontaneous �swerve� of atoms, which accounted for the freedom of  motion in man and animals; the infinity of the universe; and the existence  of gods as beatified and immortal natures completely extraneous to hap�  penings in the world. In ethics, the basic concepts were the identification  of the good with pleasure and of the supreme good with the absence of  bodily and mental pain; the limitation of all desire and the practice of  virtue; withdrawal from public life; and the cultivation of friendship.  Because of its dogmatic character and its practical end. Epicureanism did  not lend itself easily to development.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>626 i Epicurus &#x25BA; episome</p><p>Epicurus \,e-pi-'kyu-r9s\ (b. 341, Samos, Greece�d. 270 bc, Athens)  Greek philosopher. He was author of an ethical  philosophy of simple pleasure, friendship, and  retirement (see Epicureanism) and a metaphysics  based on atomism. His school in Athens, the Gar�  den, competed with the Academy of Plato and the  Lyceum of Aristotle. Unlike both of these schools,  it admitted women, and even one of Epicurus�s  slaves. It taught the avoidance of political activity  and of public life. Notwithstanding the usual con�  notations of the term epicurean today, life at the  school was simple. He was a widely appealing  figure in Rome during the 1st century bc; the poet-  philosopher Lucretius based his work on Epicurus�s  thought. His atomism was revived in the 17th cen�  tury by Pierre Gassendi (1592-1655).</p><p>Epidaurus \,e-pi-'d6r-3s\ Town, ancient Greece.</p><p>An important commercial centre in the northeast�  ern Peloponnese, it was famed for its 4th-  century-BC temple of Asclepius. Excavations of the  sacred precinct have uncovered that temple and  other buildings, including a theatre, stadium, and  hospital. Offerings of small clay body parts have  been found, and inscriptions record divine medical cures. Originally Ionic,  Epidaurus became Doric under the influence of Argos, to which it owed  religious allegiance; politically it remained independent until Roman  times.</p><p>epidemiology \ l e-p3-,de-me- , a-b-je\ Study of disease distribution in  populations. It focuses on groups rather than individuals and often takes  a historical perspective. Descriptive epidemiology surveys a population  to see what segments (e.g., age, sex, ethnic group, occupation) are affected  by a disorder, follows changes or variations in its incidence or mortality  over time and in different locations, and helps identify syndromes or sug�  gest associations with risk factors. Analytic epidemiology conducts stud�  ies to test the conclusions of descriptive surveys or laboratory  observations. Epidemiologic data on diseases is used to find those at high  risk, identify causes and take preventive measures, and plan new health  services.</p><p>epidote \'e-p3-,dot\ Any of a group of colourless to green or yellow-  green silicate minerals with the general chemical formula  A 2 Z?3(Si0 4 )(Si 2 0 7 )0(0H), in which A is usually calcium (Ca) and B is  generally aluminum (Al), although other elements are sometimes substi�  tuted. The epidote minerals occur as reaction products of other (earlier)  minerals in low-grade (formed under relatively low-temperature, low-  pressure conditions), regionally metamorphosed rocks, where their occur�  rence is used as an indicator of metamorphic grade.</p><p>epidote-amphibolite facies Ve-po-.dot-am-'fi-bo-.lIt-'fa-shezN One  of the major divisions of the mineral facies classification of metamorphic  rocks, encompassing rocks that formed under moderate temperature (500-  750�F, or 250-400�C) and pressure conditions. This facies grades into the  greenschist facies under less intense metamorphic conditions and into the  amphibolite facies with greater temperature and pressure. Typical minerals  include biotite, almandine garnet, plagioclase, epidote, and amphibole.  Chlorite, muscovite, staurolite, and chloritoid may also occur.</p><p>epigram Short poem treating concisely, pointedly, and often satirically  a single thought or event and often ending with a witticism or ingenious  turn of thought. By extension, the term applies to a terse, sage, or witty  (often paradoxical) saying, usually in the form of a generalization. Writ�  ers of Latin epigrams included Catullus and Martial. The form was revived  in the Renaissance. Later masters of the epigram have included Ben Jon-  son; Francois VI, duke de La Rochefoucauld; Voltaire; Alexander Pope;  Samuel Taylor Coleridge; Oscar Wilde; and George Bernard Shaw.</p><p>epilepsy Neurological disorder caused by paroxysmal malfunction of  neurons in the brain (seizures). It is characterized by strange movements  or sensations in parts of the body, odd behaviours, emotional disturbances,  and sometimes convulsions and momentary lapses of consciousness. Sei�  zures may result from abnormal electrical activity in most or all of the  brain (generalized), or they may originate in a specific brain area (par�  tial). Causes include brain tumours, infections, genetic or developmental  abnormalities, stroke, and head trauma, although no cause can be found</p><p>in most cases. Treatment is usually with anticonvulsant medications; brain  surgery may be beneficial if drugs cannot control seizures.</p><p>epinephrine X.e-po-'ne-fronX or adrenaline \9-'dre-n 3 l-3n\ One of  two hormones (the other being norepinephrine) secreted by the adrenal  glands, as well as at some nerve endings (see neuron), where they serve  as neurotransmitters. They are similar chemically and have similar actions  on the body. They increase the rate and force of heart contractions,  increasing blood output and raising blood pressure. Epinephrine also stimu�  lates breakdown of glycogen to glucose in the liver, raising blood glucose  levels, and both hormones increase the level of circulating free fatty acids.  All these actions ready the body for action in times of stress or danger,  times requiring increased alertness or exertion. Epinephrine is used in  medical situations including cardiac arrest, asthma, and acute allergic reac�  tion (see allergy). See also dopamine.</p><p>Epiphany Christian festival celebrated on January 6. One of the oldest  Christian holy days (along with Christmas and Easter), the festival origi�  nated in the Eastern church and was adopted in the Western church by the  4th century. It commemorates the first manifestation of Jesus to the Gen�  tiles, as represented by the Magi. The eve of Epiphany, called Twelfth  Night, is thought to mark the arrival of the Wise Men in Bethlehem.  Epiphany also celebrates the (much later) baptism of Jesus by John the  Baptist and Jesus� first miracle, performed at Cana.</p><p>epiphyte Any plant that grows upon or is attached to another plant or  object merely for physical support. Epiphytes are found mostly in the  tropics and are also known as air plants because they have no attachment  to the ground or other obvious nutrient source. They obtain water and  minerals from rain and from debris on the supporting plants. Orchids,  ferns, and members of the pineapple family are common tropical epiphytes.  Lichens, mosses, liverworts, and algae are epiphytes of temperate regions.</p><p>Epirus \i-'pl-r3s\ Ancient country, northwestern Greece. It was bounded  by Illyria, Macedonia, Thessaly, Aetolia, Acarnania, and the Ionian Sea. In  the Neolithic Period Epirus was populated by peoples from the southwest�  ern Balkans, who brought with them the Greek language and who may  have been among the founders of Mycenae. Epirus was the launching area  of the Dorian invasions (1100-1000 bc) into Greece. A princess from Epi�  rus was married to Philip II of Macedon; their son was Alexander the Great.  The area became a Roman province in the 2nd century bc, and later it was  part of the Byzantine Empire. An independent state in 1204 ad, Epirus was  taken in 1430 by the Ottoman Turks. Greece gained the southern part of  the region by 1919; the northern part is now in southern Albania.</p><p>episcopacy Xi-'pis-ko-po-seV System of church government by bishops.  It existed as early as the 2nd century ad, when bishops were chosen to  oversee preaching and worship within a specific region, now called a dio�  cese. Today local congregations are shepherded by priests and deacons,  but only bishops can ordain priests, perform the rite of confirmation, and  consecrate other bishops. Their special duties are closely tied to the idea  of Apostolic succession. Some Protestant churches abandoned episcopacy  during the Reformation, but it was retained by the Roman Catholic, East�  ern Orthodox, Anglican, and Swedish Lutheran churches, among others.</p><p>Episcopal Church, USA also called Episcopal Church in the  United States of America or Protestant Episcopal Church</p><p>Descendant of the Church of England in the U.S. Part of the Anglican  Communion, it was formally organized in 1789 as the successor of the  Church of England in the former British colonies. The church accepts both  the Apostles� Creed and the Nicene Creed, as well as a modified version  of the Thirty-nine Articles of the Church of England. The highest author�  ity in the church is the General Convention, which is headed by the pre�  siding bishop (elected by the House of Bishops). The Reformed Episcopal  Church broke away from the main body in 1873. The church accepted the  ordination of women in 1976. In 1988 the church elected its first woman  bishop, and in 2003 an openly gay man was consecrated bishop of New  Hampshire. These steps generated controversy within the church as well  as among other churches of the Anglican Communion.</p><p>episome Ve-po-.somN Any of a group of genetic elements consisting of  DNA and capable of giving selective advantage to the bacteria in which  they occur. Episomes may be attached to the bacterial cell membrane or  become part of the chromosome. Cells with episomes act like males dur�  ing conjugation, a mating process in certain bacteria. During conjugation,  cells lacking the episome may receive either the episome or the episome  plus the genes to which it is attached.

For example, when  the gene responsible for albinism occurs, the genes that determine skin  color are present but not expressed; the gene for albinism is therefore  called an epistatic gene.</p><p>epistemology Study of the origin, nature, and limits of human knowl�  edge. Nearly every great philosopher has contributed to the epistemologi�  cal literature. Some historically important issues in epistemology are: (1)  whether knowledge of any kind is possible, and if so what kind; (2)  whether some human knowledge is innate (i.e., present, in some sense,  at birth) or whether instead all significant knowledge is acquired through  experience (see empiricism; rationalism); (3) whether knowledge is inher�  ently a mental state (see behaviourism); (4) whether certainty is a form of  knowledge; and (5) whether the primary task of epistemology is to pro�  vide justifications for broad categories of knowledge claim or merely to  describe what kinds of things are known and how that knowledge is  acquired. Issues related to (1) arise in the consideration of skepticism, radi�  cal versions of which challenge the possibility of knowledge of matters  of fact, knowledge of an external world, and knowledge of the existence  and natures of other minds.</p><p>epistolary Vi-'pis-to-.ler-e, 1 e-pi- , stol-9-re\ novel Novel in the form of  a series of letters written by one or more characters. It allows the author  to present the characters� thoughts without interference, convey events  with dramatic immediacy, and present events from several points of view.  It was one of the first novelistic forms to be developed. It was foreshad�  owed by Aphra Behn�s poem cycle Love-Letters Between a Nobleman and  His Sister (1683). The outstanding early example is Samuel Richardson�s  Pamela (1740); distinguished later works include Tobias Smollett�s  Humphry Clinker (1771) and Pierre Laclos�s Les Liaisons dangereuses  (1782). The genre remained popular up to the 19th century. Its reliance  on subjective points of view makes it the forerunner of the modern psy�  chological novel.</p><p>epitaph Ve-po-.tafX Inscription in verse or prose on a tomb, or, by exten�  sion, anything written as if to be inscribed on a tomb. Probably the ear�  liest surviving epitaphs are those written on ancient Egyptian sarcophagi  and coffins. Ancient Greek examples are often of literary interest. In Eliza�  bethan times epitaphs began to assume a more literary character. Many  of the best known are literary memorials (often deliberately witty) not  intended for a tomb.</p><p>epitaxy Process of growing a crystal of a particular orientation on top  of another crystal. If both crystals are of the same material, the process  is known as homoepitaxy; if the materials are different, it is known as  heteroepitaxy. Common types of epitaxy include vapour phase, liquid  phase, and solid phase, according to the source of the atoms being  arranged on the substrate. Epitaxy is most frequently employed in the  production of semiconductor wafers for use in the creation of integrated  circuits.</p><p>epithalamium N.e-po-tho-'la-me-onA or epithalamion X.e-po-tho-  Ta-me-3n\ Nuptial song or poem in honour or praise of a bride and bride�  groom. In ancient Greece such songs were a traditional way of invoking  good fortune on a marriage and often of indulging in ribaldry. The ear�  liest evidence for literary epithalamiums are fragments by Sappho; the  oldest surviving Latin examples are three by Catullus. In the Renaissance,  epithalamiums based on classical models were written in Italy, France,  and England; that of Edmund Spenser (1595) is considered the finest in  English.</p><p>epoch Unit of geologic time during which a rock series is deposited. It  is a subdivision of a geologic period. Additional distinctions can be made  by adding relative time terms, such as early, middle, and late. The use of  the term is usually restricted to divisions of the Tertiary and Quaternary  PERIODS.</p><p>Epona Ve-po-noX Horse goddess of the ancient Celtic religion. Associ�  ated with kingship and fertility, she was known as Epona in Gaul, Rhi-  annon in Wales, and Macha in Ireland. Her cult was found throughout the  Western Roman empire and was spread by members of the Roman army,  especially cavalry units.</p><p>epoxy \i-'pak-se\ Any of a class of thermosetting polymers, polyethers  built up from monomers with an ether group that takes the form of a three-  membered epoxide ring. The familiar two-part epoxy adhesives consist of  a resin with epoxide rings at the ends of its molecules and a curing agent  containing amines or anhydrides. When mixed, these react to yield, after  curing, a complex network with ether groups linking the monomers.  Stable, tough, and resistant to corrosive chemicals, epoxies are excellent  adhesives and useful surface coatings.</p><p>EPROM \ l e-,pram\ in full erasable programmable read-only  memory Form of computer memory that does not lose its content when  the power supply is cut off and that can be erased and reused. EPROMs  are generally employed for programs designed for repeated use (such as  the BIOS) but that can be upgraded with a later version of the program.</p><p>Epstein Vep-.stlnV Sir Jacob (b. Nov. 10, 1880, New York, N.Y.,  U.S.�d. Aug. 21, 1959, London, Eng.) U.S.-born British sculptor. He  studied in Paris and settled in England in 1905. His 18 nude figures known  as the Strand Statues (1907-08) provoked charges of indecency; his nude  angel on the tomb of Oscar Wilde (1912) in Paris was also attacked. In  1913 he became affiliated with Vorticism and developed a style character�  ized by simple forms and calm surfaces carved from stone; his works often  partly retained the shape of the original block, or sometimes they were  modeled in plaster. He is best known for religious and allegorical figures  carved in colossal blocks of stone and for bronze portrait busts of celeb�  rities. Occasionally he produced monumental bronze groups, such as St.  Michael and the Devil (1958) for Coventry Cathedral.</p><p>Epstein-Barr X.ep-.stln-'barX virus (EBV) Virus of the Herpesviridae  family that is the major cause of acute infectious mononucleosis. The virus,  named for two of its discoverers, infects only salivary gland cells and one  type of white blood cell. Saliva is the only bodily fluid that has been  proved to contain infectious EBV particles. In less-developed nations,  infection with EBV occurs in almost all children before the age of 5 and  is not associated with recognizable symptoms. When EBV infection is  delayed until the teen or early adult years, the body commonly responds  differently, resulting in mononucleosis. Other, rarer disorders have also  been linked with EBV, including certain cancers. There are no specific  treatments for any form of EBV infection, and no vaccines have been  developed.</p><p>equal-field system Chinese land-distribution system, ad 485-8th  century. Borrowed by Japan in 646, it lasted about a century there. Under  the system, all adults were assigned a fixed amount of land; a portion of  its produce was paid as taxes. On a person�s death, most of the land was  returned to the government. Increases in population and a tendency for  the land to come to be held permanently led to the system�s collapse in  China; tax-free status and additional allotments for nobles and monaster�  ies resulted in its demise in Japan.</p><p>equal protection In U.S. law, the constitutional guarantee that no per�  son or group will be denied such protection under the law as is enjoyed  by similar persons or groups�i.e., persons similarly situated must be  treated similarly. The 14th Amendment to the Constitution of the United  States prohibits states from denying any person �the equal protection of  the laws.� Until the mid-20th century the requirement was applied  minimally�except in some cases of racial discrimination, such as the use  of literacy tests and grandfather clauses to restrict the voting rights of  blacks. In Plessyv. Ferguson (1896), the Supreme Court of the United States  upheld �separate but equal� facilities for the races, thus sanctioning racial  segregation. Beginning in the 1960s, the court under Chief Justice Earl  Warren dramatically expanded the concept, applying it to cases involv�  ing welfare benefits, exclusionary zoning, municipal services, and school  financing. During the tenure of Chief Justices Warren E. Burger and Wil�  liam H. Rehnquist, the court continued to add to the types of cases that  might be adjudicated under equal protection, including cases involving  sexual discrimination, the status and rights of aliens, abortion rights, and  access to the courts.</p><p>Equal Rights Amendment (ERA) Proposed but unratified amend�  ment to the U.S. Constitution designed mainly to invalidate many state  and federal laws that discriminated against women. Its central tenet was  that sex should not be a determining factor in establishing the legal rights  of individuals. It was first introduced in Congress in 1923, shortly after  women obtained the right to vote. It was finally approved by the U.S.  Senate 49 years later (1972) but was subsequently ratified by only 30 of  the 50 state legislatures. Critics claimed it would cause women to lose</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>628 i equality &#x25BA; equine</p><p>privileges and protections, such as exemption from compulsory military  service and economic support by their husbands. Supporters, led by the  National Organization for Women, argued that discriminatory state and  federal laws left many women in a state of economic dependency.</p><p>equality Generally, an ideal of uniformity in treatment or status by those  in a position to affect either. Acknowledgment of the right to equality often  must be coerced from the advantaged by the disadvantaged. Equality of  opportunity was the founding creed of U.S. society, but equality among  all peoples and between the sexes has proved easier to legislate than to  achieve in practice. Social or religious inequality is deeply ingrained in  some cultures and thus difficult to overcome (see caste). Government  efforts to achieve economic equality include enhancing opportunities  through tax policy, subsidized training and education, redistributing  wealth or resources, and preferential treatment of those historically treated  unequally (see affirmative action).

In essence, equations are questions, and the  development of mathematics has been driven by attempts to find answers  to those questions in a systematic way. Equations vary in complexity from  simple algebraic equations (involving only addition or multiplication) to  differential equations, exponential equations (involving exponential  expressions), and integral equations. They are used to express many of the  laws of physics.

This geographic, or terrestrial, Equator divides the Earth into the  Northern and Southern Hemispheres and forms the imaginary reference  line on the Earth�s surface from which latitude is reckoned (i.e., 0� lati�  tude). In astronomy, the celestial equator is the great circle in which the  plane of the terrestrial Equator intersects the celestial sphere; it is thus  equidistant from the celestial poles. When the Sun lies in its plane, day  and night are everywhere of equal length; this happens at the EQUlNOXes.</p><p>Equatorial Africa See French Equatorial Africa  equatorial coordinates See celestial coordinates</p><p>Equatorial Guinea officially Republic of Equatorial Guinea  formerly Spanish Guinea Country, on the western coast of equatorial  Africa and including Bioko Island. Area: 10,831 sq mi (28,051 sq km).  Population (2005 est.): 504,000. Capital: Malabo. The majority of the  mainland population are Bantu-speaking Fang people, with a minority of  other Bantu-speaking ethnic groups (see Bantu languages). The majority  on Bioko are Bubi, descendants of Bantu migrants from the mainland.  Languages: Spanish, French (both official), Pidgin English (commonly  spoken). Religions: Christianity (predominantly Roman Catholic, also  other Christians, Protestant); also Islam, traditional beliefs. Currency:  CFA franc. Bordered by Cameroon and Gabon, Equatorial Guinea�s main�  land region is separated by the Bight of Biafra from the island of Bioko  to the northwest. The mainland has a coastal plain some 12 mi (20 km)  wide, with a long stretch of beach, low cliffs to the south, and hills and  plateaus to the east. The Benito River divides the region. Bioko consists  of three extinct volcanic cones and has several crater lakes and rich lava  soils. Dense tropical rainforest prevails throughout the mainland and  includes valuable hardwoods. Animal life has been decimated by over�  hunting. Cacao, timber, and coffee are exported from the country, but since  the 1990s petroleum is the major export. Equatorial Guinea is a republic  with one legislative house; its chief of state is the president, and the head  of government is the prime minister. The first inhabitants of the mainland  appear to have been Bantu-speaking people. The now-prominent Fang and  Bubi reached the mainland in the Bantu migrations of the late 19th and  the early 20th century. Equatorial Guinea was ceded by the Portuguese  to the Spanish in the late 18th century; it was frequented by slave trad�  ers, as well as by British and other merchants. Bioko was administered</p><p>declared in 1968, followed by a reign of  terror and economic chaos under the dictatorial president Macias Nguema,  who was overthrown by a military coup in 1979 and later executed.  Teodoro Obiang Nguema Mbasogo became leader of the country in 1979.  A new constitution was adopted in 1982, but political unrest persisted into  the 21st century despite the country�s oil wealth.</p><p>eques \'e-,kwes, 'e-,kwez\ (Latin: �horseman�) In ancient Rome, a  knight. In early Rome, the equites (in full, equites equo publico, �horse�  men with mounts provided at public expense�) were of the senatorial  class. They were the most influential members of the Comitia Centuriata.  By the early 4th century bc, non-senators could be equites, providing their  own horses. Augustus reorganized them as a military class, removing them  from politics; qualifications were free birth, good health and character,  and wealth. In the 1st century ad, equites were permitted civil careers,  and they became particularly involved in financial administration.</p><p>equilibrium Condition in which the net force acting on a particle is  zero. A body in equilibrium experiences no acceleration and, unless dis�  turbed by an outside force, will remain in equilibrium indefinitely. A stable  equilibrium is one in which small, externally induced displacements from  that state produce forces that tend to oppose the displacement and return  the body to equilibrium. An unstable equilibrium is one in which the least  departures produce forces tending to increase the displacement. A brick  lying on the floor is in stable equilibrium, while a ball bearing balanced  on a knife-edge is in unstable equilibrium.</p><p>equilibrium, chemical Condition in the course of a reversible chemi�  cal reaction in which no net change in the amounts of reactants and prod�  ucts occurs: Products are reverting to reactants at the same rate as  reactants are forming products. For practical purposes, the reaction under  those conditions is completed. Expressed in terms of the law of mass  action, the reaction rate to form products is equal to the reaction rate to  re-form reactants. The ratio of the reaction rate constants (i.e., of the  amounts of reactants and products, each raised to the proper power),  defines the equilibrium constant. Changing the conditions of temperature  or pressure changes the reaction�s equilibrium; a high temperature or pres�  sure may be used to �push� a reaction that at ordinary conditions makes  little product.

The vernal equi�  nox, when spring begins in the Northern Hemisphere, occurs about March  21, when the Sun moves north across the celestial equator. The autumnal  equinox falls about September 23, as the Sun crosses the celestial equa�  tor going south. See also solstice.</p><p>equinoxes, precession of the Motion of the points where the Sun  crosses the celestial equator, caused by precession of Earth�s axis. Hippar�  chus noticed that the stars� positions were shifted consistently from ear�  lier measures, indicating that Earth, not the stars, was moving. This  precession, a wobbling in the orientation of Earth�s axis with a cycle of  almost 26,000 years, is caused by the gravity of the Sun and the Moon  acting on Earth�s equatorial bulge. The planets also have a small influ�  ence on precession. Projecting Earth�s axis onto the celestial sphere locates  the northern and southern celestial poles. Precession makes these points  trace out circles on the sky and also makes the celestial equator wobble,  changing its points of intersection (EQUiNOXes) with the ecliptic.</p><p>equipartition of energy See equipartition of energy  equistetum See horsetail</p><p>equity Finance and accounting concept. Equity represents any of three  separate but related values: the money value of a property or of an inter�  est in a property in excess of claims or liens against it; a risk interest or  ownership right in property; and the common stock of a corporation. In  corporate finance, a basic equation holds that a company�s total assets  minus total liabilities equals total owners� equity.</p><p>equity Justice according to fairness, especially as distinguished from  mechanical application of rules under common law. Courts of equity (also  called chancery courts) arose in England in the 14th century in response  to the increasingly strict rules of proof and other requirements of the  courts of law. Equity provided remedies not available under the old writ  system. Often these remedies involved something other than damages,  such as specific performance of contractual obligations, enforcement of a  trust, restitution of goods wrongfully acquired, imposition of an injunc�  tion, or the correction and cancellation of false or misleading documents.  The equity courts eventually established their own precedents, rules, and  doctrines and began to rival the law courts in power. The two systems  were united in 1873. Courts of equity also developed early in U.S. his�  tory, but by the early 20th century most jurisdictions had combined them  with courts of law into a single system. Modern courts apply both legal  and equitable principles and offer both legal and equitable relief.</p><p>equivalence principle Fundamental principle of physics that in its  weak form states that gravitational (see gravitation) and inertial (see iner�  tia) masses are the same. Albert Einstein�s stronger version states that gravi�  tation and acceleration are indistinguishable. It implies that the effect of  gravity is removed in a suitably accelerated reference frame, such as an  elevator with its cable cut, in which a person would experience free fall.</p><p>equivalence relation In mathematics, a generalization of the idea of  equality between elements of a SET. All equivalence relations (e.g., that  symbolized by the equals sign) obey three conditions: reflexivity (every  element is in the relation to itself), symmetry (element A has the same  relation to element B that B has to A), and transitivity (see transitive law).  Congruence of triangles is an equivalence relation in geometry. Members  of a set are said to be in the same equivalence class if they have an  equivalence relation.</p><p>equivalent weight or combining weight Quantity of an element  that exactly reacts with (equals the combining value of) 1 g of hydrogen,  8 g of oxygen, or a corresponding amount of any other element. An  element�s equivalent weight is its atomic weight divided by its valence. In  general, for oxidation-reduction, including electrolysis, the equivalent  weight is the weight associated with the loss or gain of 6.02 x 10 23 elec�  trons (Avogadro's number) or 96,500 coulombs of electric charge; this is  also the molecular weight divided by the number of electrons lost or gained.  The equivalent weight of a substance with several valences differs depend�  ing on the number of electrons transferred in the given reaction. The</p><p>number of equivalent weights of any substance dissolved in one litre of  solution is called the solution�s normality (N). See also stoichiometry.</p><p>Er, Lake Chinese Er Hai \'er-'hl\ or Erh Hai Lake, western Yunnan  province, China.

Oct. 27, 1469, Rotterdam,  Holland�d. July 12,1536, Basel, Switz.) Dutch priest and humanist, con�  sidered the greatest European scholar of the 16th century. The illegitimate  son of a priest and a physician�s daughter, he entered a monastery and was  ordained a priest in 1492. He studied at the University of Paris and trav�  eled throughout Europe, coming under the influence of St. Thomas More  and John Colet. The book that first made him famous was the Adagia  (1500, 1508), an annotated collection of Greek and Latin proverbs. He  became noted for his editions of Classical authors, Church Fathers, and the  New Testament as well as for his own works, including Handbook of a  Christian Knight (1503) and Praise of Folly (1509). Using the philological  methods pioneered by Italian humanists, he helped lay the groundwork for  the historical-critical study of the past. By criticizing ecclesiastical abuses,  he encouraged the growing urge for reform, which found expression both  in the Protestant Reformation and in the Catholic Counter-Reformation.  Though he saw much to admire in Martin Luther, he came under pressure  to attack him; he took an independent stance, rejecting both Luther�s doc�  trine of predestination and the powers claimed for the papacy.</p><p>Eratosthenes \ l er-9- , tas-th9-,nez\ of Cyrene (b. c. 276 bc, Cyrene,  Libya�d. c. 194, Alexandria, Egypt) Greek scientific writer, astronomer,  and poet.

He is the first person known to have calculated the Earth�s circum�  ference, though the exact length of the units (stadia) he used is uncertain.  He also measured the tilt of Earth�s axis with great accuracy, compiled a  star catalog, worked out a calendar that included leap years, and tried to fix  the dates of literary and political events since the siege of Troy.</p><p>Erbakan \,er-ba-'kan\, Necmettin (b. c. 1926, Sinop, Tur.) First  leader of an Islamic political party to win a general election in Turkey  (1995). Son of an Ottoman-era religious court judge, he studied mechani�  cal engineering before being elected to the National Assembly in 1969.  Despite Turkey�s strong secular tradition and its laws prohibiting the for�  mation of parties based on religious ideology, Erbakan formed an Islamic  party in 1970 and another in 1972, serving twice as deputy prime min�  ister. His third attempt to form a party created the Refah ("Welfare") Party,  which won the most seats in the 1995 elections. As prime minister, he  formed a coalition government in 1996, but his party was outlawed in  1997; he was then banned from politics.</p><p>Ercker, Lazarus (b. c. 1530, Annaberg, Saxony�d. c. 1594, Prague,  Bohemia) German writer on early metallurgy.

Located  northwest of Ur on the Euphrates River, it was one of the greatest cities of  Sumer and was enclosed by brickwork walls that, according to legend,  were built by the mythical hero Gilgamesh. Excavations have traced suc�  cessive cities that date from the prehistoric Ubaid period (c. 5000 bc) to  Parthian times (126 bc-ad 224), when in c. 70 bc an ancient school of  learned scribes was still using cuneiform script. Urban life in what is  known as the Erech-Jamdat Nasr period (c. 3500-2900 bc) is more fully  illustrated at Erech than at any other Mesopotamian city.</p><p>Erechtheus \i-'rek-,thus, i-'rek-the-os\ Legendary god-king of Athens.  According to Homer�s Iliad , he was born from the earth and raised by  Athena, who established him in her temple at Athens.

Jointly  with its neighbour Chalkis, it founded Cumae in Italy (c. 750 bc), the first  of the Greek colonies in the west. Subsequent rivalry with Chalkis cul�  minated in war, and by the Classical period Chalkis was the leading city  of Euboea. In 499-498 bc Eretrian triremes sailed to support the Ionian  revolt against Persia, for which act Darius I destroyed the city (490 bc) and  deported the population. It was rebuilt, but under Macedonian and Roman  rule it became insignificant. There are extensive ruins at the site.</p><p>Erfurt \'er-,furt\ City (pop., 2002 est.: 200,126), central Germany.

Erfurt was granted  municipal rights c. 1250 and joined the Hanseatic League in the 15th cen�  tury. The city passed to Prussia in 1802, forming part of Prussian Saxony  until 1945. Erfurt was the site of the first meeting of the leaders of East  and West Germany in 1970. It is dominated by its 12th-century cathedral;  other buildings include the monastery where Martin Luther was a monk  (1505-08). Erfurt is an important road and railway junction and a com�  mercial centre.</p><p>ergativify Tendency of a language to pair the subject, or agent, of an  intransitive verb with the object, or patient, of a transitive verb. This con�  trasts with the situation in nominative-accusative languages such as Latin  or English, in which the subjects of both transitive and intransitive verbs  are paired grammatically and distinguished from the object of a transitive  verb.

He moved to England in 1826, where he constructed a steam loco�  motive (1829) and later devised a caloric engine and patented a screw  propeller. He immigrated to the U.S in 1839. During the Civil War he  proposed, designed, and built a novel warship, the Monitor. Its battle with  the Confederacy�s Merrimack led the government to place an order for  many more such vessels. Wholly steam-powered and with a screw pro�  peller and an armoured revolving turret, it set a new pattern for U.S. war�  ships that continued until the 20th century. He later developed a torpedo  and investigated solar-powered motors.</p><p>Eridu Ver-i-.dii, e-'re-du\ Ancient Sumerian city on the Persian Gulf.  Although it was the chief seaport of Sumer and Babylonia and was located  on the Euphrates River near the city of Ur, siltation has since moved the  coastline southward and the city�s remains are now some 120 mi (200  km) inland, in modern Iraq. It was revered as the oldest city in Sumer,  and its patron god was Enki (Ea). Founded on sand dunes c. 5th millen�  nium bc, its ruins show the sequence of the preliterate Ubaid civilization,  with a long succession of superimposed temples portraying the develop�  ment of an elaborate mud-brick architecture.

The  Detroit River carries inflow from Lake Huron to the west, and the lake  discharges at its eastern end through the Niagara River. It is an important  link in the St. Lawrence Seaway; its ports handle steel, iron ore, coal, and  grain. The area was once inhabited by Erie Indians; when the French  arrived in the 17th century they found the Iroquois living there. The Brit�  ish were in the region in the 18th century, and the U.S. shores were settled  after 1796.

On the Division of Nature (862-  66) tries to reconcile Neoplatonism with the Christian doctrine of creation;  for its pantheistic implications, it too was condemned. His Latin transla�  tions of major works of Greek patristic literature made them accessible to  Western thinkers.

Trained in Vienna by Anna Freud, in 1933 he immigrated to the U.S.,  where he practiced child psychoanalysis in Boston and joined the Har�  vard Medical School faculty. In 1936 he moved to Yale University, and  in 1938 he began his first studies of cultural influences on psychological  development, working with Sioux Indian children and later with the Yurok  Indians. He later taught at the University of California at Berkeley but  left in 1950, in the era of McCarthy ism, after refusing to sign a loyalty  oath vowing support of the Constitution of the U.S. Personality develop�  ment, in Erikson�s view, takes place through a series of identity crises  that must be overcome and internalized in preparation for the next devel�  opmental stage; he posited eight such stages. His other concerns included  social psychology and the interactions of psychology with history, poli�  tics, and culture.

It extends about 600 mi (1,000 km) along  the Red Sea coast and includes the Dahlak Archipelago. Area: 46,770 sq</p><p>guage. The varied population is about half  Tigrinya-speaking (see Tigray) Christians, with a large minority of Mus�  lims and diverse other peoples. Arabic, English, and Italian are also spo�  ken. Currency: nakfa. The land varies from temperate central highlands  to coastal desert plain, with savanna and open woodlands in the western  lowlands. The economy is based on livestock herding and subsistence  agriculture. Industry, based in Asmara, includes food products, textiles,  and leather goods; exports include salt, hides, cement, and gum arabic.  Eritrea�s form of government is a transitional regime with one interim  legislative body; the head of state and government is the president. As the  site of the main ports of the Aksumite empire, it was linked to the begin�  nings of the Ethiopian kingdom, but it retained much of its independence  until it came under Ottoman rule in the 16th century. In the 17th-19th  centuries, control of the territory was disputed among Ethiopia, the Otto�  mans, the kingdom of Tigray, Egypt, and Italy; it became an Italian colony  in 1890. Eritrea was used as the main base for the Italian invasions of  Ethiopia (1896, 1935-36) and in 1936 became part of Italian East Africa.  It was captured by the British in 1941, federated to Ethiopia in 1952, and  made a province of Ethiopia in 1962. Three decades of guerrilla warfare  by Eritrean secessionist groups ensued. A provisional Eritrean government  was established in 1991 after the overthrow of the Ethiopian government,  and independence came in 1993. A new constitution was ratified in 1997.  A border war with Ethiopia that began in 1998 ended in an Ethiopian vic�  tory in 2000.</p><p>Erivan See Yerevan</p><p>Erlitou \'er-le-'t6\ culture Neolithic culture (1900-1350 bc) of the cen�  tral plains of northern China.

Erosion is caused by wind action, river and stream processes,  marine processes (sea waves), and glacial processes. The complementary  actions of erosion and deposition or sedimentation operate through wind,  moving water, and ice to alter existing landforms and create new land-  forms. Erosion will often occur after rock has been disintegrated or altered  through weathering. Moving water is the most important natural agent of</p><p>erosion. Sea wave erosion results primarily from the impact of waves  striking the shore and the abrasive action of sand and pebbles agitated by  wave action. Erosion by rivers is caused by the scouring action of the  sediment-containing flowing water. Glacial erosion occurs by surface  abrasion as the ice, embedded with debris, moves slowly over the ground  accompanied by the plucking of rock from the surface. Wind plays a key  role in arid regions as blowing sand breaks down rock and dislodges sur�  face sand from unprotected sand dunes. Human intervention, as by the  removal of natural vegetation for farming or grazing purposes, can lead  to or accelerate erosion by wind and water. See also sheet erosion.</p><p>error In applied mathematics, the difference between a value and an  estimate of that value. In statistics, a common example is the difference  between the mean age of a given group of people (see mean, median, and  mode) and that of a sample drawn from the group. In numerical analysis,  an example of round-off error is the difference between the true value of  Pl and commonly substituted expressions like 22 /i and shorter versions like  3.14159. Truncation error results from using only the first few terms of  an infinite series. Relative error is the ratio of the size of an error to the  size of the quantity measured, and percentage error is relative error  expressed as a percent.</p><p>Erskine Vor-skonV (of Restormel), Thomas Erskine, 1 st Baron</p><p>(b.

After service in the British navy and army,  he entered the law, and in 1778 he was called to the bar. His practice  flourished after he won a seminal libel case, and he went on to make  important contributions to the protection of personal liberties. His defense  of politicians and reformers on charges of treason and related offenses,  including an unsuccessful defense of Thomas Paine (1792), checked repres�  sive measures taken by the British government in the aftermath of the  French Revolution. He contributed to the law of criminal responsibility  by defending, on the novel ground of insanity, a would-be assassin of  George III. He served in Parliament (1783-84, 1790-1806) until elevated  to the peerage (1806), and he was lord chancellor (1806-07) in William  Grenville�s �ministry of all talents.� In 1820 he defended Queen Caro�  line, whom George IV had brought to trial before the House of Lords for  adultery in order to deprive her of her rights and title.

If blood typing shows incompatibility, an  anti-Rh antibody injection given to the mother after the birth can destroy  the fetal red cells, thus preventing trouble in a future pregnancy. If amnio�  centesis detects products of blood destruction, Rh-negative blood transfu�  sions to the fetus before birth or exchange transfusion after it may save  the baby�s life.

Mythological eschatologies depict an eternal  struggle between order and chaos and celebrate the eternity of order and  the repeatability of the origin of the world. The most notable expression  of mythological eschatology is in Hinduism, which maintains belief in great  cycles of the destruction and creation of the universe. Historical escha�  tologies are grounded in datable events that are perceived as fundamen�  tal to the progress of history. Judaism, Christianity, and Islam all have  historical eschatologies. Eschatology in the Hebrew Scriptures sees the  catastrophes that beset the people of Israel as due to their disobedience  to the laws and will of God and holds that conformity to God�s plan will  result in renewal and the fulfillment of God�s purpose. In Christianity, the  end times are thought to have begun with the life and ministry of Jesus,  the Messiah who will return to establish the Kingdom of God. Millennialism  focuses especially on Christ�s second coming and the reign of the righ�  teous on earth. In ShCite Islam it is believed that the mahdi, or restorer of  the faith, will come to inaugurate the last judgment, in which the good  will enter heaven and the evil will fall into hell.

Esparto leaves are used in the manufacture of  paper.</p><p>Esperanto ^es-po-'ran-toN Artificial language created in 1887 by Laz�  arus Ludwig Zamenhof (1859-1917), a Polish oculist, for use as an inter�  national second language. Zamenhof�s Fundamento de Esperanto (1905)  outlines its basic principles. All words, derived from roots commonly  found in the European languages, are spelled as pronounced, and gram�  mar is simple and regular. Nouns have no gender and end in -o, and there  is only one definite article, la (e.g., la amiko, �the friend�). Adjectives are  marked by the ending -a. Verbs are regular and have only one form for  each tense or mood. The Universal Esperanto Association (founded 1908)  has members in 83 countries. Estimates of the number of Esperanto-  speakers range from 100,000 to several million.</p><p>espionage Ves-pe-3-,nazh\ Practice of obtaining military, political,  commercial, or other secret information by means of spies or illegal moni�  toring devices. It is sometimes distinguished from the broader category  of intelligence gathering by its aggressive nature and its illegality. Coun�  terespionage efforts are directed at detecting and thwarting espionage by  others.</p><p>Espiritu Santo formerly Marina Island, northwestern Vanuatu, South  Pacific Ocean. Vanuatu�s largest island, Espfritu Santo is 76 mi (122 km)  long and 45 mi (72 km) wide and covers 1,420 sq mi (3,677 sq km). Vol�  canic in origin, it has a mountain range running along its western coast;  Mount Tabwemasana rises to 6,165 ft (1,879 m). It is heavily wooded and  has broad, fertile, well-watered valleys. Agriculturally developed, its prin�  cipal settlement is Luganville (Santo) on the southeastern coast.</p><p>Esquire U.S. monthly magazine, founded in 1933 by Arnold Gingrich.  It began as an oversized magazine for men that featured a sophisticated  style and drawings of scantily clad young women. It later abandoned the  risque drawings but continued to cultivate the image of affluence and  refined taste. It pioneered the treatment of unconventional topics and fea�  ture stories and attracted a general-interest audience with pieces by well-  known writers. In the 1940s, because of its early notoriety, it was the  object of an ultimately unsuccessful court case challenging its worthiness  for mailing privileges at desirable rates. By the late 20th century, Esquire  had lost its literary distinctiveness.</p><p>essay Analytic, interpretative, or critical literary composition, usually  dealing with its subject from a limited and often personal point of view.  Flexible and versatile, the essay was perfected by Michel de Montaigne,  who chose the name essai to emphasize that his compositions were  �attempts� to express his thoughts and experiences. The essay has been  the vehicle of literary and social criticism for some, while for others it  could serve semipolitical, nationalistic, or polemical purposes and could  have a detached, playful, earnest, or bitter tone.</p><p>Essen City (pop., 2002 est.: city, 591,889; metro, area, 5,823,685), North  Rhine-Westphalia state, western Germany. Located on the Ruhr River, it  is the site of an extensive ironworks and steelworks. It was originally the  seat of a convent (founded 852), whose 15th-century cathedral still stands.  Essen became a city in the 10th century and was locally sovereign until  1802, when it passed to Prussia. The development of ironworks, steel�  works, and coal mines stimulated growth in the 19th century. The city  was largely destroyed in World War II, when it was targeted by the Allies  as a centre of the German war industry. It has since been rebuilt with large,  modern buildings, including concert halls, an economic research institute,  and an art institute.</p><p>Essene \i-'sen, 'e-sen \ Member of a Jewish sect active in Palestine from  the 2nd century bc to the 1st century ad. The Essenes formed small monas�  tic communities whose members strictly observed the laws of Moses and  the Sabbath and held their property in common. They withdrew from  society, avoiding temple worship in Jerusalem and supporting themselves  by manual labor. They usually excluded women. It is likely that the Dead  Sea Scrolls were composed, copied, or collected by the Essenes.</p><p>essential oil Any of a class of highly volatile (readily evaporating)  organic compounds found in plants and usually named for them (e.g., rose  oil, peppermint oil). They have been known and traded since ancient  times. Many essential oils contain isoprenoids. Some, such as oil of win-  tergreen (methyl salicylate) and orange oil (d-limonene), have one pre�  dominant component, but most have dozens or hundreds. Trace  components impart an oil�s characteristic odour, which synthetic or  blended oils can rarely duplicate. Essential oils have three primary com�  mercial uses: as odorants in perfumes, soaps, detergents, and other prod�  ucts; as flavours in baked goods, candies, soft drinks, and many other  foods; and as pharmaceuticals, in dental products and many medicines  (see aromatherapy).</p><p>essentialism In ontology, the view that some properties of objects are  essential to them. The �essence� of a thing is conceived as the totality of  its essential properties. Theories of essentialism differ with respect to their  conception of what it means to say that a property is essential to an object.  The concept of an essential property is closely related to the concept of  necessity, since one way of saying that a property P is essential to an object  O is to say that the proposition �O has P� is necessarily true (see neces�  sity). A general but not very informative way of characterizing essential  properties is to say that a property is essential to an object if the object  cannot lack the property and still be the object that it is. Properties of an  object that are not essential in this sense are said to be accidental. See  also IDENTITY OF INDISCERNABLES.</p><p>Essequibo \,e-se-'kwe-bo\ River River, east-central Guyana. The larg�  est river between the Amazon and the Orinoco rivers and the longest in  Guyana, it rises in the Acarai Mountains on the Brazilian border. It flows  north for about 630 mi (1,000 km) to empty into the Atlantic Ocean 13  mi (21 km) from Georgetown. Its estuary, 20 mi (32 km) wide, is  obstructed by islands and silt but is navigable by small ocean vessels to  Bartica, 50 mi (80 km) inland.</p><p>Essex Administrative (pop., 2001: 1,310,922), geographic, and historic  county, eastern England. It extends along the North Sea coastline between  the estuaries of the Rivers Thames and Stour. Chelmsford, centrally situ�  ated, has long been the county headquarters and is also the seat of a church  diocese. The ancient county stretched west as far as Middlesex, but Greater  London now incorporates its southwestern comer. It was a Roman centre  until the 5th-century Saxon invasions; it became one of the Anglo-Saxon  kingdoms of the Heptarchy and had its centre at London. It came under  Danish control in the 9th century and was later reconquered by Wessex.  Despite its proximity to London, much of Essex remains rural, and the  county is highly farmed; it is also the site of petroleum installations on  the River Thames and of a nuclear power plant. The University of Essex  is at Colchester.</p><p>Essex Junto Vjon-.toX Informal group of Federalist Party political lead�  ers in Massachusetts, mainly from Essex county. Its members supported  Alexander Hamilton and friendship with Britain and opposed Thomas Jef�  ferson, the Embargo Act, and the War of 1812. Its leaders, including  Timothy Pickering, tried to form a separate confederation in New England  and participated in the Hartford Convention. They declined in importance  after 1814.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>636 i Essex &#x25BA; Estienne</p><p>Essex, Robert Devereux, 2nd earl of (b. Nov. 10, 1567, Neth-  erwood, Herefordshire, Eng.�d.</p><p>Feb. 25, 1601, London) English sol�  dier and courtier. He was the son of  the 1st earl of Essex. As a young man,  he became the aging Elizabeth I�s  favorite, though their relationship  was stormy. In 1591-92 he com�  manded the English force in France  that helped Henry IV fight the French  Roman Catholics, and in 1596 he  commanded forces in the sack of  Cadiz. In 1599 Elizabeth sent him to  Ireland as lord lieutenant, where he  fought an unsuccessful campaign  against Irish rebels and concluded an  unfavorable truce, leading Elizabeth  to deprive him of his offices in 1600.</p><p>In 1601 he made an unsuccessful  attempt to raise the populace of Lon�  don in revolt against Elizabeth; he  was captured, tried by his former  mentor Francis Bacon, and beheaded.</p><p>Essex, Robert Devereux, 3rd  earl of (b. 1591, London, Eng.�d.</p><p>Sept. 14, 1646, London) English  military commander. Son of the 2nd earl of Essex, he began his military  career in 1620 and commanded forces for Charles I until the Long Parlia�  ment deposed Charles�s ministers (1640). As the English Civil Wars began,  he was appointed to command the Parliamentary army. He fought against  the Royalists at the indecisive Battle of Edgehill (1642) and advanced on  London in 1643. His army was besieged at Lostwithiel, Cornwall, in 1644,  and all surrendered except Essex, who escaped by sea. He resigned his  command in 1645.</p><p>Essex, Walter Devereux, 1st earl of (b. Sept. 16, 1541, Car�  marthen, Carmarthenshire, Wales�d. Sept. 22, 1576, Dublin, Ire.)  English soldier. Born to a titled family, he helped suppress a rebellion in  northern England in 1569 and was made earl of Essex in 1572. In 1573  he offered to subdue and colonize, at his own expense, a portion of Ulster  that had not accepted English overlordship. There he treacherously cap�  tured and executed the Irish rebel leaders and massacred hundreds of the  populace, contributing to Irish bitterness toward the English. Elizabeth I  commanded him to break off the enterprise in 1575. He died of dysen�  tery shortly after returning to Ireland from England.</p><p>establishment clause or establishment-of-religion clause</p><p>Clause in the 1st Amendment to the U.S. Constitution forbidding Con�  gress from establishing a state religion. It prevents the passage of any law  that gives preference to or forces belief in any one religion. It is paired  with a clause that prohibits limiting the free expression of religion.</p><p>estate law Laws governing the nature and extent of an owner�s rights  with respect to real and personal property. When used in connection with  probate proceedings, it refers to the laws governing the disposition of the  total property of whatever kind owned by a person at the time of death.  See also estate tax, property, property tax.</p><p>estate tax Levy on the value of property changing hands at the death  of the owner, fixed mainly by reference to its total value. Estate tax is  generally applied only to estates whose value exceeds a set amount, and  it is applied at graduated rates. An estate tax was first instituted in the  U.S. in 1898 to help finance the Spanish-American War; it was repealed  in 1902 but permanently reimposed in 1916, initially to help finance mobi�  lization for World War I. Methods of avoiding estate tax (e.g., gifts and  trust funds) were largely foiled by the U.S. Tax Reform Act of 1976.</p><p>Estates General or States General French Etats-Generaux.</p><p>In pre-Revolutionary France, the representative assembly of the three  �estates� or orders of the realm: the clergy and the nobility (both privi�  leged minorities) as well as the Third Estate, which represented the major�  ity of the people. Usually summoned by monarchs in times of crisis, the  Estates General met at irregular intervals from the 14th century on; it was  of limited effectiveness because the monarchy usually dealt with local  Estates instead. The last meeting of the Estates General was at the start</p><p>of the French Revolution in 1789, when the deputies of the Third Estate  led in founding the National Assembly.</p><p>Este family \'es-ta\ Princely family of Lombard origin prominent in the  history of medieval and Renaissance Italy. The Estensi, a branch of the  10th-century dynasty of the Obertenghi, took their name from the town�  ship and castle of Este, near Padua. The founder of the family was the  margrave Alberto Azzo II (died 1097), through whose son Folco I (died  1136?) descended the House of Este. The family first gained prominence  as leaders of the Guelphs in the wars between the Guelphs and Ghibelunes.  Members of the family ruled in Ferrara in the 13th-16th century. After  Alfonso II (1533-1597), the fifth and last duke of Ferrara, died childless,  direct papal rule was established in Ferrara in 1598, and the main branch  of the Este family came to an end. The family also ruled in Modena and  Reggio from the late Middle Ages to the late 18th century. In addition to  their political prominence, members of the family also played an impor�  tant role as promoters of art and culture.</p><p>Estenssoro, Victor Paz See Victor Paz Estenssoro</p><p>ester Any of a class of organic compounds that can react with water (see  hydrolysis) to produce an alcohol and an organic or inorganic acid. They  are formed by the reverse process, esterification, in which acid reacts with  alcohol to form an ester and water. Esters of carboxylic acids, the most  common esters, contain the acid�s carbonyl group (�C=0; see func�  tional group); the carbon�s fourth bond is with the alcohol�s oxygen atom.  Hydrolysis of esters in the presence of an alkali (saponification) is used  to make soaps from fats and oils. Carboxylic acid esters of low molecu�  lar weight are colourless, volatile liquids with pleasant odours; they give  flavour and fragrance to fruits and flowers and are used as synthetic fla�  vours and fragrances. Others, such as ethyl acetate and butyl acetate, are  used as solvents for lacquers, paints, and varnishes. Certain polymers are  esters, including Lucite (polymethyl methacrylate) and Dacron (polyeth�  ylene terephthalate). Esters of alcohols and inorganic acids include nitrate  esters (e.g., nitroglycerin), which are explosive; phosphate esters, includ�  ing such biologically important compounds as nucleic acids; and others  that are used as flame retardants, solvents, plasticizers, gasoline and oil  additives, and insecticides.</p><p>Esterhazy family Ves-t9r-,ha-ze\ Aristocratic Magyar family, dating  from at least the 15th century, that produced numerous Hungarian diplo�  mats, army officers, and patrons of the arts. By the 18th century the Ester-  hazys were the largest landowners in Hungary and possessed a private  fortune even larger than that of the Habsburg emperors, whom they sup�  ported. The great Esterhazy palace was built at Eisenstadt, on Neusiedler  Lake. FJ. Haydn spent most of his career as music director at the palace.  The family�s various members held important governmental, ecclesiasti�  cal, diplomatic, and military posts in Hungary well into the 20th century.</p><p>Estes \'es-tez\, William K(aye) (b.

He  taught at Stanford, Rockefeller, and Harvard universities, among others.  Estes�s later work focused on �cognitive architectures.� His works include  Learning Theory and Mental Development (1970), Statistical Models in  Behavioral Research (1991), and Classification and Cognition (1994). In  1997 he received the National Medal of Science.</p><p>Esther Heroine and central figure in the book of Esther. She was a beau�  tiful Jewish woman, the wife of the Persian king Ahasuerus (Xerxes I). She  and her cousin Mordecai persuaded the king to cancel an order for the  extermination of Jews in his realm, plotted by the king�s chief minister,  Haman. Instead, Haman was hanged on the gallows he had built for Mor�  decai, and the Jews were given permission to destroy their enemies. The  Jewish festival of Purim celebrates this event. The book of Esther was  probably written in the 2nd century bc.</p><p>Estienne \a-'tyen\, Henri II or Henri II Etienne (b. 1528, Paris,  France�d. 1598, Lyon) French scholar-printer.

It consists of a mainland area and some 1,500 islands and islets in the  Baltic Sea. Area: 17,462 sq mi (45,227 sq km). Population (2005 est.):</p><p>1,345,000. Capital: Tallinn. Estonians  make up about two-thirds of the popula-  l '' 3 ' o *' eo km' h� n - R uss i ans account for almost one-</p><p>--� third, and there are Ukrainian, Finnish,</p><p>and Belarusian minorities. Language:  Estonian (official). Religion: Christianity (other Christians [mostly unaf�  filiated], Protestant, Eastern Orthodox). Currency: kroon. The land is low  and hilly, with numerous lakes, forests, and rivers. It has a cool-temperate  and humid climate. The economy is mainly industrial, producing shale  oil, machinery, fabricated metal products, and building materials. It is  noted for its textiles, and woodworking is a traditional and important  industry. Estonia is a republic with one legislative body; the chief of state  is the president, and the head of government is the prime minister. It was  invaded by Vikings in the 9th century ad and later by Danes, Swedes, and  Russians, but the Estonians were able to withstand the assaults until the  Danes took control in 1219. In 1346 the Danes sold their sovereignty over  Estonia to the Teutonic Order, which was then in possession of Livonia  (southern Estonia and Latvia). In the mid-16th century Estonia was once  again divided: northern Estonia capitulated to Sweden, and Poland gained  Livonia, which it surrendered to Sweden in 1629. Russia acquired Livo�  nia and Estonia in 1721. Nearly a century later, serfdom was abolished.  From 1881 Estonia underwent intensive Russification. In 1918 Estonia  obtained independence from Russia, which lasted until the Soviet Union  occupied the country in 1940 and forcibly incorporated it into the U.S.S.R.  Germany held the region (1941-44) during World War II, but the Soviet  regime was restored in 1944, after which Estonia�s economy was collec�  tivized and integrated into that of the Soviet Union. In 1991, along with  other parts of the former U.S.S.R., Estonia proclaimed its independence  and subsequently held elections. In the 21st century Estonia continued  negotiations with Russia to settle their common border, and, along with  the other Baltic states, it joined the European Union in 2004.</p><p>Estremadura See Extremadura</p><p>estrogen Ves-trs-jofo Any of a class of hormones that primarily influ�  ence the female reproductive system�s development, maturation, and func�  tion. The three major estrogens�estradiol, estrone, and estriol�are  produced mainly by the ovaries and placenta; the adrenal glands and the  testes secrete smaller amounts. Estrogens affect the ovaries, vagina, fal�  lopian tubes, uterus, and mammary glands and play crucial roles in puberty,  menstruation, pregnancy, and parturition (labour). They also influence the  structural differences between female and male bodies. In experimental  animals, loss of estrogens diminishes mating desires and other behavioral  patterns.</p><p>estrus Period in the sexual cycle of female mammals, except the higher  primates, during which they are in heat (ready to accept a male for mat�  ing). Some animals (e.g., dogs) have only one heat during a breeding sea�  son; others (e.g., ground squirrels) will come into heat repeatedly during  the breeding season until impregnated. During estrus the female secretes  pheromones that signal her receptivity to the males; her genital area may  become swollen, and she may also give behavioral signals.</p><p>estuary Ves-cho-.wer-eX Partly enclosed coastal body of water in which  river water is mixed with seawater. An estuary is thus defined by salinity  rather than geography. Many coastal features designated by other names  are in fact estuaries (e.g., Chesapeake Bay). Some of the oldest continu�  ous civilizations have flourished in estuarine environments (e.g., the land  between the Tigris and Euphrates rivers, the Nile delta, the Ganges delta,  and the lower Huang He valley). Cities such as London (River Thames),  New York (Hudson River), and Montreal (St. Lawrence River) developed  on estuaries and became important commercial centres.</p><p>Etana Epic \a-'ta-na\ Ancient Mesopotamian myth concerning dynastic  succession. The gods chose Etana as the first king, but his wife, though  pregnant, could not give birth, and thus Etana had no heir. The god Sha-  mash answered Etana�s prayers by directing him to rescue a maimed eagle,  which rewarded Etana by carrying him high up in the sky, near heaven,  where Etana could obtain the birth plant to help his wife. Surviving texts  are incomplete and divergent: in one version Etana makes it to heaven  (but the text then breaks off); in another he falls to earth. A king named  Etana ruled Kish in southern Mesopotamia sometime in the 3rd millen�  nium BC.</p><p>etching Method of engraving in which lines or textures are bitten, or  etched, into a metal plate, usually copper, with acid. The image produced  has a spontaneity of line that comes from drawing on the plate in the same  direct way as with pen or pencil on paper. The first etchings date from  the early 16th century, but the basic principle had been used earlier for  the decoration of armour. Among the pioneers of the medium were Al�  brecht Altdorfer, Albrecht DOrer, and Parmigianino; the greatest of all etch�  ers was Rembrandt. In the 20th century, etching was especially popular for  book illustration. See also aquatint; engraving.</p><p>ethanol \'e-th3-,n6l\ or ethyl alcohol or grain alcohol Organic  compound, most important of the alcohols, chemical formula  CH 3 CH 2 OH. Produced by fermentation, it is the intoxicating ingredient in  alcoholic beverages. Ethanol for industrial purposes is made by either fer�  mentation or chemical synthesis, then purified by distillation and, to avoid  the tax levied on ethyl alcohol for drinking, made unfit to drink (see dena-  turation) by mixing it with compounds such as methanol, benzene, or kero�  sene. Ethanol has many uses as a solvent, a raw material, an extraction  medium, an antifreeze, an antiseptic, and a gasoline additive and substi�  tute. It is toxic, depressing the central nervous system, and addictive to  some persons (see alcoholism). Moderate amounts depress the inhibitory  activities of the brain and so appear to stimulate the mind, but larger  amounts seriously impair coordination and judgment; excessive consump�  tion can cause coma and death. Taking ethanol in combination with bar�  biturates or related drugs is especially dangerous.</p><p>Ethelbert I or Aethelberht I (d. Feb. 24, 616) King of Kent (560-  616).

When Sweyn I was accepted as king in England in 1013, Ethel-  red fled to Normandy. He returned to the throne on the death of Sweyn  in 1014, but on his death he was succeeded by the Dane Canute the Great.

Ethers have the general chemical for�  mula ROR', in which R and R' represent the hydrocarbons. They resemble  alcohols but generally are less dense, less soluble in water, more volatile,  and more inert. They are used in chemical processing, for extraction and  separation of chemicals, and as solvents. Some are used as insecticides  and soil fumigants. They are also used in medicine and pharmacology.  Codeine is the methyl ether of morphine. The term ether often refers to  ethyl ether (C 2 H 5 OC 2 H 5 ), best known as an anesthetic but also used as a  solvent, an extractant, and a reaction medium.</p><p>Etherege \'eth-rij\, Sir George (b. c. 1635, Maidenhead, Berkshire,  Eng.?�d. c. May 10, 1692) British playwright. He is remembered as the  creator of the Restoration comedy of manners. His first comedy. Love in  a Tub (1664), was an immediate success and was novel in its lively  exploitation of contemporary manners. He also wrote She Wou�d if She  Cou�d (1668) and the popular The Man of Mode (1676). Though his own  plays ceased to be performed after the 18th century, his style of comedy  was adopted by later playwrights and persisted into modern times.</p><p>Ethernet Telecommunications networking protocol introduced by  Xerox Corp. in 1979. It was developed as an inexpensive way of sending  information quickly between office machines connected together in a  single room or building, but it rapidly became a standard computer inter�  connection method. The original data rate of 10 megabits per second has  been increased to 100 megabits per second for a new standard known as  fast ethemet. The original specification required coaxial cable as the com�  munications medium, but costs have been reduced through the employ�  ment of simple paired wires. See also computer network.</p><p>ethical relativism Philosophical view that what is right or wrong and  good or bad is not absolute but variable and relative, depending on the per�  son, circumstances, or social situation. Rather than claiming that an  action�s rightness or wrongness can depend on the circumstances, or that  people�s beliefs about right and wrong are relative to their social condi�  tioning, it claims (in one common form) that what is truly right depends  solely on what the individual or the society thinks is right. Because what  people think will vary with time and place, what is right will also vary. If,  however, changing and even conflicting moral principles are equally valid,  there is apparently no objective way of justifying any principle as valid for  all people and all societies. This conclusion is rejected by consequentialists  (see consequentiausm) and deontologists (see deontological ethics) alike.</p><p>ethics Branch of philosophy concerned with the nature of ultimate value  and the standards by which human actions can be judged right or wrong.  The term is also applied to any system or theory of moral values or prin�  ciples. Ethics is traditionally subdivided into normative ethics, metaeth�  ics, and applied ethics. Normative ethics seeks to establish norms or  standards of conduct; a crucial question in this field is whether actions are  to be judged right or wrong based on their consequences or based on their  conformity to some moral rule, such as �Do not tell a lie.� Theories that  adopt the former basis of judgment are called consequentialist (see con-  sequentialism); those that adopt the latter are known as deontological (see  deontological ethics). Metaethics is concerned with the nature of ethical  judgments and theories. Since the beginning of the 20th century, much  work in metaethics has focused on the logical and semantic aspects of  moral language. Some major metaethical theories are naturalism (see  NATURAUSTIC FALLACY), INTUITIONISM, EMOTIVISM, and PRESCRIPTIVISM. Applied eth-  ics, as the name implies, consists of the application of normative ethical  theories to practical moral problems (e.g., abortion). Among the major  fields of applied ethics are bioethics, business ethics, legal ethics, and  medical ethics.</p><p>Ethiopia \,e-the-'o-pe-3\ officially Federal Democratic Republic  of Ethiopia formerly Abyssinia Country, eastern Africa. It is situated  on the Horn of Africa, the continent�s easternmost projection. Area:</p><p>435,186 sq mi (1,127,127 sq km). Popula�  tion (2005 est.): 73,053,000. Capital: Addis  Ababa. The people are about one-third  Amhara and one-third Oromo, with the bal�  ance mostly Tigray, Afar, Somali, Saho, and</p><p>Agew. Languages: Amharic, Oromo. Religions: Christianity (predomi�  nantly Ethiopian Orthodox; also Protestant), Islam, traditional beliefs. Cur�  rency: birr. The landlocked country is mountainous in the north, with  lowlands to the east and west. The central Ethiopian Plateau is split by the  Great Rift Valley, which divides the eastern and western highlands. The cli�  mate is temperate in the highlands, which are mainly savanna, and hot in  the arid lowlands. Intensive farming and deforestation have led to severe  erosion; this, along with periodic droughts, has produced periodic food  shortages. The country�s once abundant wildlife has been decimated; many  species are endangered. Ethiopia is one of the world�s poorest countries.  Agriculture is mainly for subsistence, with cereals the main crop. Live�  stock is also important. Coffee is the main export, followed by hides and  skins. A new republic was established in 1995; it has two legislative houses,  the chief of state is the president, and the head of government is the prime  minister. Ethiopia, the Biblical land of Kush, was inhabited from earliest  antiquity and was once under ancient Egyptian rule. Ge'ez-speaking agri�  culturalists established the kingdom of Da�amat in the 7th century bc. After  300 bc they were superseded by the kingdom of Aksum, whose King  Menilek I was, according to legend, the son of King Solomon and the  Queen of Sheba. Christianity was introduced in the 4th century ad and  became widespread (see Ethiopian Orthodox Church). Ethiopia�s prosper�  ous Mediterranean trade was cut off by the Muslim Arabs in the 7th-8th  century, and the area�s interests were directed southward. Contact with  Europe resumed in the late 15th century with the arrival of the Portuguese.  Modem Ethiopia began with the reign of Tewodros II, who began the con�  solidation of the country. In the wake of European encroachment, the  coastal region was made an Italian colony in 1889, but under Emperor  Menilek II the Italians were defeated and ousted in 1896. Ethiopia prospered  under his rule, and his modernization programs were continued by  Emperor Haile Selassie in the 1930s. In 1936 Italy again gained control of  the country and held it as part of Italian East Africa until 1941, when it was  occupied by the British. Ethiopia incorporated Eritrea in 1952. In 1974  Haile Selassie was deposed, and a Marxist government, plagued by civil  wars and famine, controlled the country until 1991. In 1993 Eritrea gained  its independence, but there were continued border conflicts with it and  neighbouring Somalia.</p><p>Ethiopian Orthodox church Independent Christian patriarchate in  Ethiopia. Traditionally thought to have been founded by the preaching of  the apostle Matthew or the eunuch of the Acts of the Apostles, the church  was established in the 4th century by St. Frumentius and his brother</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Ethiopianism &#x25BA; Etobicoke I 639</p><p>Aedesius. Based in Addis Ababa, the church adheres to Monophysite  doctrine (see Monophysite heresy). It accepts the honorary primacy of the  Coptic patriarch of Alexandria, who appointed its archbishops from the  12th century until 1959, when an autonomous Ethiopian patriarchate was  established. Its customs include circumcision, rigorous fasting, and the  participation of laypersons known as debtera, who perform liturgical  music and dances and act as astrologers, scribes, and fortune-tellers. Its  principal adherents are the Amhara and Tigray peoples of the northern  and central highlands. See also Coptic Orthodox church.</p><p>Ethiopianism Religious movement among sub-Saharan Africans during  the colonial era. It originated in South Africa in the 1880s, with the forma�  tion of all-African Christian churches such as the Tembu tribal church and  the Church of Africa. The term was first used by Mangena Mokone when  he founded the Ethiopian Church in 1892. Africans resented the blatant rac�  ism of European colonialists, who denied them advancement in religious  and political hierarchies. They also wanted a version of Christianity rel�  evant for Africa and a return to tribal life. Parallel developments occurred  in Nigeria, Cameroon, Ghana, Kenya, and other locations. Ethiopian  movements played some part in the Zulu rebellion of 1906 and the Nyasa-  land rising of 1915. In the 1920s political aspirations moved away from  religion and became tied to political parties and trade unions.</p><p>Ethiopic \,e-the-'o-pik\ languages Group of Semitic languages, spo�  ken by more than 25 million people in Eritrea and Ethiopia. Ethiopic has  been divided by linguists into North Ethiopic, comprising Ge�ez, Tigre,  and Tigrinya (or Tigrai), and South Ethiopic, comprising the rest of the  22 languages. Ge�ez (or Ethiopic) is the oldest Ethiopian Semitic lan�  guage, first attested in inscriptions from the kingdom of Aksum. It became  the language of Christianity in the Aksumite period, and�though prob�  ably extinct as a vernacular sometime before the 10th century ad �it  remained the classical language of highland Ethiopian civilization and the  liturgical language of the Ethiopian Orthodox church into the 20th century.  Tigre has about 800,000 speakers in northern Eritrea, while Tigrinya has  about 4 million speakers. The estimated 1.3 million Tigrinya speakers in  Eritrea constitute about 50% of the country�s population. The most impor�  tant South Ethiopic language is Amharic.</p><p>ethnic cleansing The creation of an ethnically homogenous geo�  graphic area through the elimination of unwanted ethnic groups by depor�  tation, forcible displacement, or genocide. Ethnic cleansing also has  involved attempts to remove physical vestiges of the targeted group in the  territory through the destruction and desecration of monuments, cemeter�  ies, and houses of worship. Although some critics of the term have  claimed that ethnic cleansing is simply a form of genocide, defenders of  the usage have noted that, whereas the murder of an ethnic, racial, or reli�  gious group is the primary intention of a genocidal policy, the chief goal  of ethnic cleansing is the establishment of homogenous lands, which may  be achieved by any of a number of methods including genocide. The term  was widely employed in the 1990s to describe the brutal treatment of  Bosniacs (Bosnian Muslims), ethnic Serbs in the Krajina region of  Croatia, and ethnic Albanians in the Serbian province of Kosovo during  the conflicts that erupted in the wake of the disintegration of Yugoslavia.</p><p>ethnic group Social group or category of the population that, in a larger  society, is set apart and bound together by common ties of language, nation�  ality, or culture. Ethnic diversity, the legacy of political conquests and  migrations, is one aspect of the social complexity found in most contem�  porary societies. The nation-state has traditionally been uneasy with ethnic  diversity, and nation-states have often attempted to eliminate or expel eth�  nic groups. Most nations today practice some form of pluralism, which usu�  ally rests on a combination of toleration, interdependence, and separatism.  The concept of ethnicity is more important today than ever, as a result of the  spread of doctrines of freedom, self-determination, and democracy. See  also CULTURE CONTACT; ETHNIC CLEANSING; ETHNOCENTRISM; RACE; RACISM.</p><p>ethnocentrism Tendency to interpret or evaluate other cultures in  terms of one�s own. Generally considered a human universal, it is evident  in the widespread practice of labeling outsiders as �savages� or �barbar�  ians� simply because their societies differ from those of the dominant cul�  ture. Early anthropologists often reflected this tendency, as did Sir John  Lubbock, who characterized all nonliterate peoples as being without reli�  gion, and Lucien Levy-Bruhl, who found them to have a �prelogical men�  tality� because their worldview was unlike that of western Europe. The  opposite of ethnocentrism is cultural relativism, the understanding of cul�  tural phenomena within the context in which they occur.</p><p>ethnography \eth-'na-gro-fe\ Descriptive study of a particular human  society. Contemporary ethnography is based almost entirely on fieldwork.  The ethnographer lives among the people who are the subject of study for  a year or more, learning the local language and participating in everyday  life while striving to maintain a degree of objective detachment. He or  she usually cultivates close relationships with �informants� who can pro�  vide specific information on aspects of cultural life. While detailed writ�  ten notes are the mainstay of fieldwork, ethnographers may also use tape  recorders, cameras, or video recorders. Contemporary ethnographies have  both influenced and been influenced by literary theory. See also Bronislaw  Malinowski; cultural anthropology.</p><p>ethnomusicology Scholarly study of music as an aspect of culture.  Taking an anthropological approach (it was originally called �compara�  tive musicology�), it has tended to focus on non-Western music, particu�  larly music of oral traditions. The field�s origins lie in the late 19th century  with the work of scholars such as Francois-Joseph Fetis (1784-1871) and  Carl Stumpf (1848-1936). Much work was motivated by the search for  musical universals, under the assumption that prehistory could be stud�  ied through research into �primitive� cultures of the present. Recogniz�  ing that traditional societies were quickly disappearing with the modern  world�s encroachment, ethnomusicologists soon put their highest priority  on collection (by field recording, using the new recording technology) and  transcription (using newly devised pitch calibrations). A number of clas�  sification schemes for comparative analysis of different musics have been  proposed, but the natural focus remains on diversity.</p><p>ethology \e-'tha-l3-je\ Study of animal behaviour. It is a combination  of laboratory and field science, with strong ties to other disciplines (e.g.,  neuroanatomy, ecology, evolution). Though many naturalists have studied  aspects of animal behaviour through the centuries, the modern science of  ethology is considered to have arisen as a discrete discipline with the work  in the 1920s of Nikolaas Tinbergen and Konrad Lorenz. Interested in the  behavioral process rather than in a particular animal group, ethologists  often study one type of behaviour (e.g., aggression) in various unrelated  animals.</p><p>ethyl alcohol See ethanol</p><p>ethylene Simplest olefin (CH 2 CH 2 ), a colourless, flammable gas with  a sweetish taste and odour. The petrochemical having the highest volume,  it occurs in petroleum and natural gas but is usually produced by heating  higher hydrocarbons (usually ethane and ethane-propane mixtures). Eth�  ylene is polymerized to polyethylene either at high pressures and tempera�  tures or by catalysis. It reacts with numerous other chemicals to produce  ethanol, solvents, gasoline additives, antifreeze, detergents, and various  plastics. In plants, ethylene is a hormone that inhibits growth and pro�  motes leaf fall and fruit ripening.</p><p>ethylene glycol Ve-tho-.len-'gll-.koH Simplest member of the glycol  family, also called 1,2-ethanediol (HOCH 2 CH 2 OH). It is a colourless, oily  liquid with a mild odour and sweet taste. Widely used as an antifreeze in  automobile cooling systems, it is also used in many other chemical pro�  cesses. It and some of its derivatives are fairly toxic. Many dogs, cats,  and wild animals are attracted by its sweetness and poisoned by drinking  ethylene glycol antifreeze that has been carelessly discarded.</p><p>ethyne See acetylene</p><p>Etna, Mount Active volcano, eastern coast of Sicily, Italy. The highest  active volcano in Europe, its elevation is more than 10,000 ft (3,200 m);  its base has a circumference of about 93 mi (150 km). Mount Etna has  repeatedly erupted over the centuries, most violently in 1669, when the  lava flow destroyed villages on the lower slope and submerged part of the  town of Catania. Activity was almost continuous in the decade following  1971, and in 1983 an eruption that lasted four months prompted authori�  ties to explode dynamite in an attempt to divert lava flows. Mount Etna  also experienced violent eruptions in 2001-02, prompting the Italian gov�  ernment to declare a state of emergency.</p><p>Etobicoke \i-'to-b3-,kok\ Former city (pop., 2001: 338,117), southeast�  ern Ontario, Canada.

It covered the region  that now comprises Tuscany and part of Umbria. Etruria was inhabited by  the Etruscans, who established a civilization by the 7th century bc. Their  chief confederation, traditionally including 12 cities, developed a culture  that reached its height in the 6th century bc. Etruscan power extended  into northern and southern Italy at its peak, but the cities of Etruria were  gradually absorbed by Rome during the 3rd century bc.</p><p>Etruscan Any member of an ancient people of Etruria, whose urban  civilization reached its height in the 6th century bc. Their origins are  obscure. By the 7th century they had incorporated all of Tuscany into their  territory, and in the 6th century they pushed north to the Po River valley  and became rulers of Rome. The Etruscans gave the city its first public  works, including walls and a sewer system. By the end of the 6th cen�  tury, pressure from other peoples in the region, including Greeks, Romans,  and Gauls, weakened Etruria. The Romans expelled their dynasty in 509  bc. The Etruscans had a commercial and agricultural civilization and left  a rich cultural heritage, including wall frescoes and realistic tomb por�  traits. Many features of their culture were adopted by the Romans. See  also Etruscan language; Etruscan religion.</p><p>Etruscan art (c. 8th-4th centuries bc) Art of the people of Etruria. The art  of the Etruscans falls into three categories: funerary, urban, and sacred.  Because of Etruscan attitudes toward the afterlife, most of the art that  remains is funerary. Characteristic achievements are the wall frescoes�  painted in two-dimensional style�and realistic terra-cotta portraits found  in tombs. Bronze reliefs and sculptures are also common. Tombs found at  Caere, carved underground out of soft volcanic rock, resemble houses.  Urban architecture was another specialty; Etruscans were among the first in  the Mediterranean to lay out cities with a grid plan, a practice copied by the  Romans. In the sacred area, Etruscan temples had a deep front porch with  columns and abundant terra-cotta roof sculptures, such as those from the  temple at Veii (late 6th century). Etruscan art was influenced by Greek art  and in turn influenced the development of realistic portraiture in Italy.</p><p>A detail from a fresco dating from the 5th century bc shows Etruscan musicians  wearing tunics and sandals.</p><p>SCALA/ART RESOURCE, NEW VORK CITY</p><p>Etruscan language Language spoken by the ancient people of Etruria  in what is now Italy. Its proposed relations with the Indo-European family  have not been generally accepted, and Etruscan remains a linguistic isolate  (i.e., unrelated to any other language). Known mainly from inscriptions</p><p>that date from the 7th century bc to the 1st century ad, Etruscan was written  in an alphabet probably derived from one of the Greek alphabets.</p><p>Etruscan religion Beliefs and practices of the ancient people of Etru�  ria in western Italy. The Etruscans believed that the gods manifested their  nature and will in every aspect of the natural world, such that every bird  and berry was a potential source of knowledge of the gods. The charac�  teristics of their more than 40 deities were often vague or changeable,  though some were later equated with the major Greek and Roman deities.  Famous for divination, the Etruscans sought to learn the future, looking  for divine signs in lightning, the livers of sacrificed animals, and the flights  of birds. Belief in the afterlife led to the construction of elaborate tombs  that were furnished as houses for the dead. Many features of Etruscan  religion were later adopted by the Romans.</p><p>Etymander River See Helmand River</p><p>eubacteria V.yii-bak-'tir-e-sV Group consisting of the true bacteria, one  of two major groups of the prokaryotes. The other is the archaebacteria,  which are as different from eubacteria as either is from eukaryotes. The  two groups are thought to have evolved separately from a common ances�  tor early in earth�s history, and they differ in fundamental ways. Virtually  all the familiar bacteria that cause diseases (e.g., E. cou, staphylococcus  and salmonella strains, mycobacteria) or are important in food, agricul�  ture, biotechnology, and other industrial activity (e.g., Lactobacillus, nitri�  fying and denitrifying bacteria, and Lactobacillus and streptomyces strains)  are eubacteria.</p><p>Euboea \yu-'be-9\ Greek Evvoia \'e-ve-a\ Island, Greece, in the  Aegean Sea. The second largest of the Greek islands, it is about 110 mi  (180 km) long and 4-30 mi (6-48 km) wide. It is mainly mountainous  but includes the fertile plain of the Lilas River, which was in antiquity a  famous horse-breeding region. Euboea is connected with Boeotia by a  bridge built by the Chalcidians. It was dominated by Athens for much of  the 5th century bc, while its main cities of Chalcis and Eretria were  involved in the Persian and Peloponnesian wars. From 146 bc it was part  of the Roman province of Macedon. Euboea was controlled by Venice  from 1366, conquered by the Turks in 1470, and passed to Greece in 1830.</p><p>eucalyptus V.yu-ks-'lip-tasN Any of the more than 500 species of mostly  very large trees in the genus Eucalyptus, in the myrtle family, native to  Australia, New Zealand, Tasmania, and nearby islands. Many species are  grown widely throughout the temperate regions of the world as shade trees  or in forestry plantations. Because they grow rapidly, many species attain  great height. The leaf glands of many species, especially E. salicifolia  and E. globulus, contain a volatile, aromatic oil known as eucalyptus oil,  used mostly in medicines. Eucalyptus wood is used extensively in Aus�  tralia as fuel, and the timber is commonly used in buildings and fencing.  The bark of many species is used in papermaking and tanning.</p><p>Eucharist Vyii-ks-rastV or Holy Communion or Lord's Supper</p><p>Christian rite commemorating the Last Supper of Jesus with his disciples.  On the night before his death, according to the Christian scriptures, Jesus  consecrated bread and wine and gave them to his disciples, saying �this is  my body� and �this is my blood.� He also commanded his followers to  repeat this rite in his memory, and the Eucharist traditionally involves con�  secration of bread and wine by the clergy and their consumption by wor�  shipers. Although celebrated spontaneously when the first Christians  gathered to share a meal, the Eucharist quickly became a central part of the  formal worship service and remained that way despite the many contro�  versies over its nature and meaning. Intended as a means of fostering unity  in the church, it has also been a source of division because of differing inter�  pretations of its nature. In Roman Catholicism the Eucharist is a sacrament,  and the bread and wine are thought to become the actual body and blood of  Jesus through transubstantiation. Anglicans and Lutherans also emphasize  the divine presence in the offering and recognize it as a sacrament, while  others regard it as a memorial with largely symbolic meaning. Also con�  troversial has been the belief in the Eucharist as a sacrifice, the renewed  offering of Christ each time the rite is celebrated at the altar.</p><p>Eucken Voi-kanV, Rudolf Christoph (b. Jan. 5, 1846, Aurich, East  Friesland�d. Sept. 14, 1926, Jena, Ger.) German philosopher. He taught  primarily at the University of Jena (1874-1920). Distrusting abstract intel-  lectualism and systematics, Eucken centred his philosophy upon actual  human experience. He maintained that man is the meeting place of nature  and spirit and that it is a human duty and privilege to overcome nature  by incessant striving after the spiritual life. A strong critic of naturalism,</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Euclid &#x25BA; Euler I 641</p><p>he held that humans are differentiated from the rest of the natural world  by their possession of a soul, an entity that cannot be explained in terms  of natural processes.

He founded a school in Alexandria during the reign  of Ptolemy I. Little is known of his life, but there are many anecdotes. In  the most famous, asked by Ptolemy if there is a shorter way to geometry  than through his Elements , Euclid replies, �There is no royal road to  geometry.� The Elements, based on the works of earlier mathematicians,  is a brilliant synthesis of old and new. It has been a major influence on  rational thought and a model for many philosophical treatises, and it has  set a standard for logical thinking and methods of proof in the sciences.  The starting point not just of Euclidean geometry but of an approach to  reasoning, it is sometimes said to be the most translated, published, and  studied work after the Bible.</p><p>Euclidean geometry Study of points, lines, angles, surfaces, and sol�  ids based on Euclid�s axioms. Its importance lies less in its results than in  the systematic method Euclid used to develop and present them. This axi�  omatic method has been the model for many systems of rational thought,  even outside mathematics, for over 2,000 years. From 10 axioms and pos�  tulates, Euclid deduced 465 theorems, or propositions, concerning aspects  of plane and solid geometric figures. This work was long held to consti�  tute an accurate description of the physical world and to provide a suf�  ficient basis for understanding it. During the 19th century, rejection of  some of Euclid�s postulates resulted in two non-Euclidean geometries that  proved just as valid and consistent.</p><p>Euclidean space In geometry, a two- or three-dimensional space in  which the axioms and postulates of Euclidean geometry apply; also, a space  in any finite number of dimensions, in which points are designated by  coordinates (one for each dimension) and the distance between two points  is given by a distance formula. The only conception of physical space for  over 2,000 years, it remains the most compelling and useful way of mod�  eling the world as it is experienced. Though non-Euclidean spaces, such  as those that emerge from elliptic geometry and hyperbolic geometry, have  led scientists to a better understanding of the universe and of mathemat�  ics itself. Euclidean space remains the point of departure for their study.</p><p>eudaemonism Xyu-'de-mo-.ni-zonA In ethics, the view that the ultimate  justification of virtuous activity is happiness. Virtuous activity may be  conceived as a means to happiness, or well-being, or as partly constitu�  tive of it (see teleological ethics).

Oct. 18, 1663, Paris, France�d. April 24, 1736, Vienna,  Austria) French-Austrian general. Born in Paris, he was the son of the  count de Soissons, of the house of Savoy-Carignan, and of Olympe Man-  cini (see Mancini family), niece of Jules Mazarin. Louis XIV severely  restrained Eugene�s ambitions, prompting him to leave France and enter  the service of Emperor Leopold I. He later served Joseph I and Charles VI.  He quickly distinguished himself in battle and advanced in rank to impe�  rial field marshal at age 29. He fought notably against the Turks in cen�  tral Europe and the Balkans and against France in the War of the Grand</p><p>Alliance and the War of the Spanish Succession. With his friend the duke  of Marlborough, he won the important victory at the Battle of Blenheim  (1704) and ousted the French from Italy. In 1718 he won a great triumph  over the Turks, taking the city of Belgrade. He later served as governor  in the Austrian Netherlands (1714-24). An outstanding strategist and an  inspired leader, he was regarded as one of the greatest soldiers of his gen�  eration.</p><p>eugenics \yu-'je-niks\ Study of human improvement by genetic means.  The first thorough exposition of eugenics was made by Francis Galton,  who in Hereditary Genius (1869) proposed that a system of arranged  marriages between men of distinction and women of wealth would even�  tually produce a gifted race. The American Eugenics Society, founded in  1926, supported Galton�s theories. U.S. eugenicists also supported restric�  tion on immigration from nations with �inferior� stock, such as Italy,  Greece, and countries of eastern Europe, and argued for the sterilization  of insane, retarded, and epileptic citizens. Sterilization laws were passed  in more than half the states, and isolated instances of involuntary steril�  ization continued into the 1970s. The assumptions of eugenicists came  under sharp criticism beginning in the 1930s and were discredited after  the German Nazis used eugenics to support the extermination of Jews,  blacks, and homosexuals.

Under the  patronage of Frederick the Great, he worked at the Berlin Academy for  many years (1744-66), where he developed the concept of function in  mathematical analysis and discovered the imaginary logarithms of nega�  tive numbers. Throughout his life he was interested in number theory. In</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>642 i Euler's formula &gt; Europa</p><p>addition to inspiring the use of arithmetic terms in writing mathematics  and physics, Euler introduced many symbols that became standard,  including � for summation; Jn for the sum of divisors of ir, e for the base  of the natural logarithm; a, b, and c for the sides of a triangle with A, B,  and C for the opposite angles; f[x) for a function; n for the ratio of the  circumference to the diameter of a circle; and i for V-l. He is considered  one of the greatest mathematicians of all time.</p><p>Euler's formula Either of two important mathematical theorems of  Leonhard Euler. The first is a topological invariance (see topology) relat�  ing the number of faces, vertices, and edges of any polyhedron. It is writ�  ten F + V = E + 2, where F is the number of faces, V the number of  vertices, and E the number of edges. A cube, for example, has 6 faces, 8  vertices, and 12 edges, and satisfies this formula. The second formula,  used in trigonometry, says e � = cos x + /sin x where e is the base of the  natural logarithm and / is the square root of -1 (see irrational number).  When x is equal to n or 2k, the formula yields two elegant expressions  relating n, e, and /: = -1 and e 2lli = 1.</p><p>Eumenes Vyii-ma-.nezX II (d. 160/159 bc) King of Pergamum (197 bc-c.  160). He continued the policy of his father, Attalus I Soter, of coopera�  tion with Rome. He helped defeat Antiochus III, thus enlarging his realm.  He brought his kingdom to its height and made it a great centre of Greek  culture; in particular, he is credited with constructing nearly all the pub�  lic buildings and sculpture on the Pergamum acropolis. He was suspected  of disloyalty in the Roman struggle against Perseus; Rome subsequently  withdrew its support, and Eumenes�s power and the glory of Pergamum  declined. His brother Attalus II became coruler c. 160 bc.</p><p>Eumolpus \yu-'mal-p3s\ Mythological ancestor of the priestly class, the  Eumolpids, at Eleusis in ancient Greece. His name means �sweet singer.�  Three divergent identities for him exist in legend: he is the father, son, or  pupil of Musaeus, a mythical singer connected with Orpheus, in one; an  originator of the Eleusinian Mysteries in another; and a king of Thrace and  son of Poseidon in a third.</p><p>eunuch Vyii-nokV Castrated human male. From remote antiquity on,  eunuchs were employed in the Middle East and China as guards and ser�  vants in harems or other women�s quarters and as chamberlains to kings.  The eunuchs� confidential position frequently enabled them to exercise an  important influence over their royal masters. Many of the patriarchs of  Constantinople during Byzantine times were eunuchs. Eunuch advisers  disappeared as a class only with the end of the Ottoman Empire.

The  winged spindle tree ( E. alata ), also called burning bush, is a handsome  shrub with corky winged stems. Wood of the common spindle tree {E.  europaea) is used for pegs and spindles; several varieties are grown as  ornamentals.</p><p>euphonium \yu-'fo-ne-9m\ or tenor tuba Large valved brass instru�  ment, the leading lower-pitched instrument in military bands. It developed  from the valved bugle and cornet in Germany c. 1840. It has four valves  and a wide conical bore resembling the tuba�s. Its range is an octave below  the trumpet and comet. It is played either vertically or with the bell fac�  ing forward. The very similar baritone has the same range and transpo�  sition and is distinguished only by its narrower bore. Both are essential  members of bands of all kinds and are often given significant solo roles.</p><p>euphorbia See spurge</p><p>Euphranor \yu-'fra-nor\ (b. c. 390 bc, Greece�d. c. 325, Athens?)  Greek sculptor and painter active in Athens. The only surviving work  identified as his is the fragments of a colossal marble statue of Apollo (c.  330 bc) found in the agora at Athens. Other recorded (but lost) works  suggest that he was one of the foremost Athenian artists of the mid 4th  century bc. He also wrote treatises on proportion and colour.</p><p>Euphrates \yu-'fra-tez\ River Turkish Firat Nehri \f3-'rat-ne-'re\  Arabic Nahr al Furat River, Middle East. The largest river in South�  west Asia, it rises in Turkey and flows southeast across Syria and through  Iraq. Formed by the confluence of the Karasu and the Murat rivers in the  high Armenian plateau, the Euphrates descends between major ranges of  the Taurus Mountains to the Syrian plateau. It then flows through western</p><p>and central Iraq to unite with the Tigris and continues, as Shatt al-Arab,  to the Persian Gulf. In all, it is 1,740 mi (2,800 km) long. Its valley was  heavily irrigated in ancient times, and many great cities, some of whose  ruins remain, lined its banks. With the Tigris, it defines an area known  historically as Mesopotamia.</p><p>Euphronius \yu-'fro-ne-9s\ or Euphronios (fl. c. 520^-70 bc, Ath�  ens, Greece) Greek vase painter and potter. His signature has been iden�  tified on 20 vessels, 8 that he signed as painter and 12 as potter. He was  an outstanding early proponent of red-figure pottery. His best-known work  as a painter is a krater in the Louvre depicting Herakles wrestling Antaeus.  As a potter, he worked with the finest vase painters of his time. His great�  est rival was Euthymides.</p><p>Eure River \'oer\ River, northern France. From its source in the Perche  Hills it flows chiefly through agricultural and wooded regions on its  140-mi (225-km) course, passing through Chartres below the cathedral,  which is located on high ground on its left bank. It joins the Seine above  Rouen.</p><p>Euripides Vyu-'ri-po-.dezN (b. c. 484 bc, Athens�d. 406 bc, Macedonia)  Greek playwright. With Aeschylus and Sophocles, he is recognized as one  of Athens�s three great tragic dramatists. An associate of the philosopher  Anaxagoras, he expressed his questions about Greek religion in his plays.  Beginning in 455, he was repeatedly chosen to compete in the dramatic  festival of Dionysus; he won his first victory in 441. He competed 22  times, writing four plays for each occasion. Of his 92 plays, about 19  survive, including Medea (431), Hippolytus (428), Electra (418), The  Trojan Women (415), Ion (413), Iphigenia at Aulis (406), and The Bac-  chae (406). Many of his plays include prologues and rely on a DEUS ex  machina. Unlike Aeschylus and Sophocles, Euripides made his characters�  tragic fates stem almost entirely from their own flawed natures and uncon�  trolled passions. In his plays chance, disorder, and human irrationality and  immorality frequently result in apparently meaningless suffering that is  looked on with indifference by the gods.</p><p>Euripus See Chalkis</p><p>Euripus \yu-'ri-p9s\ Strait or Evripos Ve-vre-,p6s\ Strait Narrow  strait in the Aegean Sea. Located between the Greek island of Euboea and  the mainland of central Greece, it is 5 mi (8 km) long and varies from 130  ft (40 m) to 1 mi (1.6 km) in width. It has strong tidal currents that reverse  directions seven or more times a day, a phenomenon still not fully under�  stood. The main port on the strait is Chalkis, an important trading centre  since the times of ancient Greece. A 130-ft (40-m) movable bridge spans  the strait at Chalkis, replacing earlier structures that dated to 411 bc.</p><p>euro Single currency of 12 countries of the European Union (EU), includ�  ing Germany, France, and Italy. The euro was adopted as a unit of  exchange in January 1999. Those who advocated the currency believed  it would strengthen Europe as an economic power, increase international  trade, simplify monetary transactions, and lead to pricing equality  throughout Europe. Euro currency notes and coins were introduced in  January 2002 and became the sole national currency in all participating  countries by March 1. Britain and Sweden decided not to adopt the euro  immediately, and voters in Denmark rejected it.</p><p>Eurocommunism Trend among European communist parties toward  independence from Soviet Communist Party doctrine in the 1970s and �80s.  The term, coined in the mid-1970s, received wide publicity after the pub�  lication of Santiago Carrillo�s Eurocommunism and the State (1977). The  Eurocommunist movement rejected the Soviet doctrine of one monolithic  world communist movement and advocated instead that each country�s  communist party base its policies on the traditions and needs of its own  country. With Mikhail Gorbachev�s encouragement, all communist parties  took independent courses in the late 1980s. Most of the European com�  munist parties declined after the breakup of the Soviet Union.</p><p>Eurodollar U.S. dollar that has been deposited outside the U.S., espe�  cially in Europe.

Her beauty inspired the love of Zeus,  who approached her in the form of a white bull and carried her off across  the sea to Crete. After bearing Zeus three sons, she married the king of</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Europe &#x25BA; European Economic Community I 643</p><p>Crete, who adopted her sons. They grew up to become King Minos of  Crete, King Rhadamanthus of the Cyclades, and Prince Sarpedon of Lycia.  On Crete she was worshiped under the name Hellotis. The continent of  Europe is named for her.</p><p>Europe Second smallest continent on Earth. It is bordered by the Arctic  Ocean, the Atlantic Ocean, and the Mediterranean, Black, and Caspian  seas. The continent�s eastern boundary runs along the Ural Mountains and  the Ural River. Its area includes numerous islands, archipelagoes, and pen�  insulas. Indented by bays, fjords, and seas, continental Europe�s irregu�  lar coastline is about 24,000 mi (38,000 km) long. Area: 4,000,000 sq mi  (10,400,000 sq km). Population (2001 est.): 666,498,000. The greater part  of Europe combines low elevations with low relief; about three-fifths of  the land is below 600 ft (180 m) above sea level, and another one-third  is between 600 and 3,000 ft (180 and 900 m). The highest points are in  the mountain systems crossing the southern part of the continent, includ�  ing the Pyrenees, Alps, Apennines, Carpathians, and Balkan Mountains. A  well-watered continent with many rivers, Europe has few sizable lakes.  Glaciers cover an area of about 44,800 sq mi (116,000 sq km), mostly in  the north. Roughly one-third of Europe is arable, and about half of that  land is devoted to cereals, principally wheat and barley. One-third is for�  ested. Europe was the first of the world�s regions to develop a modern  economy based on commercial agriculture and industry, and it remains  one of the world�s major industrial regions, with average annual income  per capita among the world�s highest. The people of Europe constitute  about one-seventh of the world�s population. Most of the continent�s  approximately 60 native languages belong to either the Romance, Ger�  manic, or Slavic language groups. Europe�s population is overwhelmingly  Christian. Modem humans supplanted the scanty Neanderthal population  in Europe about 40,000 years ago, and by the beginning of the 2nd mil�  lennium bc the general population groups that would become the histori�  cal peoples and countries of Europe were in place. The Greek civilizations  were the earliest in Europe, and in the Classical period the Greeks were  a conduit for the advanced civilizations of the Middle East, which, along  with the unique Greek contribution, laid the foundation for European  civilization. By the mid-2nd century bc the Greeks had come under  Roman control, and the vast Roman Empire brought to the conquered  parts of Europe the civilization the Greeks had begun. It was through the  Romans that Christianity penetrated into Europe. The Roman Empire in  the West finally collapsed in the 5th century ad, which led to an exten�  sive breakdown of Classical civilization. This civilization was not to be  revived until the Renaissance (15th-16th centuries), which began the mod�  em European traditions of science, exploration, and discovery. The Prot�  estant Reformation of the 16th century ended the dominance of the Roman  Catholic church over western and northern Europe, and the Enlightenment  period of the 17th and 18th centuries stressed the primacy of reason. In  the late 18th century, Enlightenment ideals helped spur the French Revo�  lution, which toppled Europe�s most powerful monarchy and spearheaded  the movement toward democracy and equality. The late 18th century also  marked the beginning of the Industrial Revolution, which led to Europe�s  military and political dominance over much of the world for the next cen�  tury. In the early 20th century the European powers were divided in World  War I, which led to the effective end of monarchy in Europe and created  a host of new countries in central and eastern Europe. World War II  marked the passing of world power from the states of western Europe and  was followed by the rise of communism in eastern Europe, with the Soviet  Union and its satellites sharply dividing the continent. The Soviet Union  collapsed in the late 20th century, leading to a general demise of com�  munism throughout the continent. Soviet satellites became independent,  and most began to democratize; East and West Germany were reunified;  and Yugoslavia and its successor states were devastated by ethnic conflict  (see Kosovo conflict; Bosnian conflict).

Established in 1949 by 10 western Euro�  pean states, it has devised international agreements on human rights and  established a number of special bodies and expert committees on social,  legal, and cultural issues. It is headquartered in Strasbourg, France. (The  Council of Europe should not be confused with the European Council,  which is a policy-making body of the European Union.)</p><p>European Aeronautic Defence and Space Co. (EADS) Euro�  pean aerospace company that is one of the world�s largest. It was formed</p><p>(2000) from the merger of Aerospatiale Matra of France, DaimlerChrysler  Aerospace (Dasa) of Germany, and Construcciones Aeronauticas S.A.  (CASA) of Spain. It holds an 80% share in the European airplane manu�  facturer Airbus S.A.S. and is responsible for the final assembly of Airbus  aircraft. It has a controlling interest in the trinational venture Astrium  (created 2000), whose facilities in France, Germany, and Great Britain  cover a broad range of the space business from ground systems and launch  vehicles to satellites and orbital infrastructure. Its Eurocopter subsidiary  produces military and civil helicopters. It also has stakes in Arianespace,  which markets the commercial services of Ariane launch vehicles; the  Eurofighter consortium to develop a multirole combat aircraft; and the  French aerospace firm Dassault.</p><p>European Atomic Energy Community (Euratom) International  organization established in 1958 to form a common market for develop�  ing peaceful uses of atomic energy. It originally had six members; it now  includes all members of the European Union. Among its aims were to  facilitate the establishment of a nuclear energy industry on a European  rather than a national scale, coordinate research, encourage construction  of power plants, establish safety regulations, and establish a common  market for trade in nuclear equipment and materials. In 1967 its govern�  ing bodies were merged into the European Community.</p><p>European Coal and Steel Community (ECSC) Administrative  agency designed to integrate the coal and steel industries of France, West  Germany, Italy, Belgium, the Netherlands, and Luxembourg. It originated  in the plan of Robert Schuman (1950) to establish a common market for  coal and steel by those countries willing to submit to an independent  authority. Created in 1952, the ECSC came to include all members of the  European Union. It initially removed barriers to trade in coal, coke, steel,  pig iron, and scrap iron; it later supervised the reduction of its members�  excess production. In 1967 its governing bodies were merged into the  European Community. When the treaty expired in 2002, the ECSC was dis�  solved.</p><p>European Community (EC) Organization formed in 1967 with the  merger of the European Economic Community, European Coal and Steel  Community, and European Atomic Energy Community. The merger created a  single Commission of the European Community and a single Council of  Ministers. Other executive, legislative, and judicial bodies also were col�  lected under the umbrella of the EC. In 1993 the EC became the basis of  the European Union, and the European Economic Community was  renamed the European Community.</p><p>European Court of Justice Judicial branch of the European Union  (EU), established in 1958 to ensure the observance of international agree�  ments negotiated by predecessor organizations of the EU. Headquartered  in Luxembourg, it reviews the legality of the acts of EU executive bod�  ies and rules on cases of civil law between member states or private par�  ties. It can invalidate the laws of EU members when they conflict with  EU law. Its bench, which is appointed by member governments, consists  of 25 judges and 8 advocates-general. Prior to 2004, the ECJ met as a full  chamber for all cases, but it now may sit as a �grand chamber� of 11  judges.

A treaty  was concluded in 1952, but the French parliament�s refusal to ratify the  treaty in 1954 brought an end to the project. One consequence of the  French action was the decision in 1955 to rearm West Germany and allow  its entry into NATO. In 1955 the EDC was replaced by the Western Euro�  pean Union.</p><p>European Economic Community (EEC) later European Com�  munity (EC) known as the Common Market Association of Euro�  pean countries designed to promote European economic unity. It was  established by the Treaty of Rome in 1957 to develop the economies of the  member states into a single common market and to build a political union  of the states of western Europe. The EEC also sought to establish a single  commercial policy toward nonmember countries, to coordinate transpor�  tation systems, agricultural policies, and general economic policies, to  remove measures restricting free competition, and to assure the mobility  of labour, capital, and entrepreneurship among member states. The liber�  alized trade policies it sponsored from the 1950s were highly successful  in increasing trade and economic prosperity in western Europe. In 1967</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>European Free Trade Association &#x25BA; Evans I 645</p><p>its governing bodies were merged into the European Community.

The EFTA�s current members are Iceland, Liechtein-  stein, Norway, and Switzerland. It was formed in 1960 by Austria, Den�  mark, Norway, Portugal, Sweden, Switzerland, and Britain as an  alternative to the European Economic Community (EEC). Some of those  countries later left the EFTA and joined the EEC. In the 1990s Iceland,  Liechtenstein, and Norway joined the European Economic Area, which  also included all members of the European Union. Each country in the  EFTA maintains its own commercial policy toward countries outside the  group.</p><p>European Parliament Legislative assembly of the European Union  (EU). Inaugurated in 1958 as the Common Assembly, the European Par�  liament originally consisted of representatives selected by the national  parliaments of member countries. Beginning in 1979, members of the  Parliament, who now number more than 700, were elected by direct uni�  versal suffrage to terms of five years. The number of members per coun�  try varies depending on population. The Parliament�s leadership is shared  by a president and 14 vice presidents, elected for 30-month terms. The  EU Council of Ministers, which represents the member states, consults  the Parliament, which is empowered to discuss whatever matters it wishes.  The Parliament�s powers were expanded with passage of the Maastricht  Treaty (1993). Although it has veto power in most areas relating to eco�  nomic integration and budgetary policy, it remains subordinate to the  Council of Ministers and does not function with the authority of a national  legislature such as the U.S. Congress or the British House of Commons.</p><p>European Space Agency (ESA) French Agence Spatiale  Europeenne Western European space and space-technology research  organization headquartered in Paris. It was founded in 1975 from the  merger of the European Launcher Development Organisation (ELDO) and  the European Space Research Organisation (ESRO), both established in  1964. Members are Austria, Belgium, Britain, Denmark, Finland, France,  Germany, Ireland, Italy, The Netherlands, Norway, Portugal, Spain, Swe�  den, and Switzerland. Canada, through a special cooperative agreement,  participates in some projects. The ESA developed the Ariane series of  space launch vehicles, and it supports a launch facility in French Guiana.  It has launched a system of meteorological satellites (Meteosat) as well  as the Giotto space probe, which examined the nucleus of Halley's Comet,  and Hipparcos, a satellite that measured the PARALLAXes, positions, and  proper motions of more than 100,000 stars. It is also a participant in the  construction of the International Space Station.</p><p>European Union (EU) Organization of European countries, formed in  1993 to oversee their economic and political integration. It was created  by the Maastricht Treaty and ratified by all members of the European Com�  munity (EC), out of which the EU developed. The successful EC had made  its members more receptive to greater integration and provided a frame�  work for unified action by member countries in security and foreign policy  and for cooperation in police and justice matters. In pursuit of its major  goal to create a common monetary system, the EU established the euro,  which replaced the national currencies of 12 of the 15 EU members in  2002. Originally confined to western Europe, the EU enlarged to include  several central and eastern European countries in the early 21st century.  The EU�s principal institutions are the European Community, the Coun�  cil of Ministers (a forum for individual ministries), the European Com�  mission (an administrative bureaucracy), the European Parliament, the  European Court of Justice, and the European Central Bank.</p><p>Eurotunnel See Channel Tunnel</p><p>eurypterid \yu-'rip-t3-rad\ Member of an extinct order (Eurypterida)  of arthropods, similar in body plan to the horseshoe crab, that lived c.  505-245 million years ago. Frequently referred to as giant scorpions, most  eurypterids were small, although Pterygotus buffaloenis, a species from  the Silurian period, was the largest arthropod ever known, reaching a length  of about 10 ft (3 m). The eurypterids lived in brackish waters. Some were  predators; others were probably bottom-dwelling scavengers.</p><p>eurythmics \yu-'rith-miks\ Method of musical training for young chil�  dren. Eurythmics was developed by Swiss musician Emile Jaques-Dalcroze  in the early years of the 20th century. It called for movements of the arms</p><p>and legs in specific ways in response to changing rhythms and pitches.  The initial aim was to encourage a physical response to music in the  young, in the hope that it would educate them musically. Very popular in  the early 20th century, it has declined in recent decades.</p><p>Eusebius of Caesarea \yu-'se-be-9s...,se-z9- , re-3\ (fl. 4th century,  Caesarea Palestinae, Palestine) Bishop and historian of early Christianity.  Baptized and ordained at Caesarea in Palestine, he may have been impris�  oned during the Roman persecutions. His fame rests on his Ecclesiasti�  cal History (312-324), which preserves portions of works no longer  extant. He became bishop of Caesarea c. 313. Accused of Arianism, he  was excommunicated in 325 but was soon exonerated by the Council of  Nicaea. He was a staunch supporter of Constantine I�s attempts to unify  and standardize Christian doctrine, and his writings include the Life of  Constantine.</p><p>euthanasia Vyii-tho-'na-zhoV or mercy killing Painless killing of a  person who has a painful, incurable disease or incapacitating disorder.  Most legal systems consider it murder, though in many jurisdictions a  physician may lawfully decide not to prolong the patient�s life or may  give drugs to relieve pain even if they shorten the patient�s life. Associa�  tions promoting legal euthanasia exist in many countries. The legalization  movement has gained ground with advancing medical technology, which  has been used to prolong the lives of patients who are enduring extreme  suffering or who are comatose or unable to communicate their wishes.  Euthanasia was legalized in The Netherlands in 2001 and in Belgium in  2002. In 1997 Oregon became the first state in the U.S. to decriminalize  physician-assisted suicide.</p><p>Euthymides Vyu-'thi-mo-.dezV (fl. c. 515-500 bc, Athens, Greece)  Greek vase painter. He was a contemporary of Euphronius. His signature  has been found on eight extant vases, six that he signed as a painter and  two as a potter. A proponent of red-figure pottery, he was noted for his  mastery of foreshortening and studies in movement. The amphora now in  Munich�s Antiquities Museum showing foreshortened figures in three-  quarter view is an outstanding example of his draftsmanship.</p><p>eutrophication Vyu-.tro-fo-'ka-shonV Gradual increase in the concen�  tration of phosphorus, nitrogen, and other plant nutrients in an aging  aquatic ecosystem such as a lake.

He secured Persian aid for Athens against Sparta. With help  from Athens and Egypt, he extended his rule over most of Cyprus and  part of Anatolia. Relations with Persia later became hostile, and he was  defeated by Persia in 381. Though he remained king of Salamis in name,  he was in fact a vassal of Persia. He was assassinated by a eunuch.</p><p>evangelicalism X.e-.van-'je-li-ko-.li-zomX Protestant movement that  stresses conversion experiences, the Bible as the only basis for faith, and  evangelism at home and abroad. The religious revival that occurred in  Europe and America during the 18th century was generally referred to as  the evangelical revival. It included Pietism in Europe, Methodism in Brit�  ain, and the Great Awakening in America. In London in 1846, the Evan�  gelical Alliance was organized by evangelical Christians from several  denominations and countries. In the U.S., the movement grew, in part,  because of the popularity of preachers such as Billy Graham, the creation  of institutions such as Wheaton College, the publishing of the periodical  Christianity Today , and the founding of professional organizations and  associations, such as the National Association of Evangelicals (1942).  Developing a sense of international and interdenominational unity, evan�  gelicals formed the World Evangelical Fellowship (WEF) in 1951. More  than 110 regional and national organizations and some 110 million people  are affiliated with the WEF, now headquartered in Singapore.

She played Lady  Bracknell in Oscar Wilde�s The  Importance of Being Earnest on  stage and screen (1952). Her other  films include Look Back in Anger  (1959), Tom Jones (1963), The Chalk  Garden (1964), and The Whisperers</p><p>(1967).</p><p>Evans, Frederick H(enry) (b.</p><p>June 26, 1853, London, Eng.�d.</p><p>June 24, 1943, London) British pho�  tographer. He first attracted attention  as a popular London bookseller and  champion of the work of George Bernard Shaw and Aubrey Beardsley.  Around 1890 he began to photograph English and French cathedrals, and  from 1898 he devoted himself exclusively to photography. His belief that  only static views of idealized beauty were worth photographing clashed  with the early 20th-century tendency to photograph fleeting images, but  his architectural photographs are considered among the world�s finest.</p><p>Evans, George Henry (b. March 25, 1805, Bromyard, Herefordshire,  Eng.�d. Feb. 2, 1856, Granville, N.J., U.S.) British-born U.S. newspa�  per editor and social reformer. He immigrated to the U.S. in 1820. In 1829  he founded the Working Man�s Advocate, the first major U.S. labour news�  paper, and cofounded the Workingmen's Party. He organized the National  Reform Association to lobby Congress for free homesteads in the West,  arguing that the availability of free land would draw away excess work�  ers from the East and keep wages high for those who remained (see  Homestead Movement). His efforts led to the passage of the Homestead Act  in 1862. He also fought for the abolition of slavery and advocated equal  rights for women.</p><p>Evans, Maurice (Herbert) (b. June 3, 1901, Dorchester, Dorset,  Eng.�d. March 12, 1989, Rottingdean, East Sussex) British-born U.S.  actor. He made his professional stage debut in 1926 and achieved his first  success in Journey�s End (1929). He moved to the U.S. in 1935 and tri�  umphed in Shakespearean roles on Broadway. During World War II he  entertained U.S. troops with a short version of Hamlet. He later starred  in Broadway revivals of four George Bernard Shaw comedies, notably  Man and Superman (1947). His greatest Broadway hit was Dial M for  Murder (1952). He starred in a television production of Macbeth (1961,  Emmy Award) and appeared in 17 films, including Rosemary�s Baby</p><p>(1968).</p><p>Evans, Oliver (b. Sept. 13, 1755, near Newport, Del.�d. April 15,  1819, New York, N.Y., U.S.) U.S. inventor. Evans began early to apply  himself to industrial problems. He invented an improved carding device  for use in the newly mechanized production of textiles. In 1784 he built  a flour mill, for which he created the first continuous production line in</p><p>any industry: all movement was automatic, power being supplied by  waterwheels, and grain was passed by conveyors and chutes through the  stages of milling and refining to emerge as finished flour. His high-  pressure steam engine (patented 1790) deserves to share the credit for the  invention often given solely to Richard Trevithick. His Amphibious Digger  (1805), a steam-engine scow that could run on both land and water, was  the first powered road vehicle to operate in the U.S. His Mars Iron Works  (founded 1806) made more than 100 steam engines for use with screw  presses for processing cotton, tobacco, and paper.</p><p>Evans, Walker (b. Nov. 3, 1903, St. Louis, Mo., U.S.�d. April 10,  1975, New Haven, Conn.) U.S. photographer. He was influenced early by  the photographs of Eugene Atget. In 1934 his images of New England  architecture were exhibited in the first one-man photographic show at the  Museum of Modern Art. From 1935 he photographed rural victims of the  Great Depression for the Farm Security Administration; these images  were published in American Photographs (1938). He collaborated with  James Agee to document the life of Alabama sharecroppers in Let Us Now  Praise Famous Men (1941). Evans�s photographs appeared without titles  or comment, in a section separate from Agee�s text, yet the whole con�  stitutes one of the finest collaborations between a photographer and a  writer. He was later an editor of Fortune magazine (1945-65) and a pro�  fessor at Yale University (1965-74).</p><p>Evans-Pritchard, Sir E(dward) E(van) (b. Sept. 21, 1902, Crow-  borough, Sussex, Eng.�d. Sept. 11, 1973, Oxford, Oxfordshire) British  social anthropologist. The most influential British social anthropologist  since Bronisiaw Malinowski and A.R. Radcliffe-Brown, Evans-Pritchard  succeeded the latter at Oxford University (1946), where he served as  mentor to a generation of students. His studies of African systems of  belief, witchcraft, religion, politics, and oral tradition remain foundational  to the study of African societies and non-Western systems of thought.  Among his major works are Witchcraft, Oracles and Magic Among the  Azande (1937), The Nuer (1940), and (with Meyer Fortes) African Politi�  cal Systems (1940).</p><p>Evansville City (pop., 2000: 121,582), southwestern Indiana, U.S. A  port on the Ohio River, it was founded in 1812 and grew as the southern  terminus of the Wabash and Erie Canal (1853), which connected Lake  Erie with the Ohio River. Coal deposits and oil fields as well as fertile  farmlands surround the city, and its location as a transportation hub has  made it the metropolis of southwestern Indiana and adjacent states. Diver�  sified manufactures include pharmaceuticals and refrigeration and air con�  ditioning equipment. It is the seat of the University of Evansville (1854).  Angel Mounds State Memorial, a large archaeological site, is nearby.</p><p>evaporation Change of a liquid into the gaseous state; in particular,  the process by which liquid water enters the atmosphere as water vapour.  Evaporation, mostly from the sea and from vegetation, replenishes the  humidity of the air. It is an important part of the exchange of energy in  the Earth-atmosphere system that produces atmospheric motion, and  therefore weather and climate. The rate of evaporation depends on the  temperature difference between the evaporating surface and the air, the  relative humidity, and wind.</p><p>evaporator Industrial apparatus for converting liquid into gas or  vapour. The single-effect evaporator consists of a container or surface and  a heating unit; the multiple-effect evaporator uses the vapour produced in  one unit to heat a succeeding unit. Double-, triple-, or quadruple-effect  evaporators may be used in industrial and steam heating plants. Some  evaporators are used to concentrate a solution by vaporizing and elimi�  nating water (e.g., in a concentration plant for sugar and syrup). In puri�  fication processes such as desalination, evaporators convert the water to  vapour, leaving mineral residues behind; the vapour is then condensed  into (desalinated) water. In a refrigeration system, the cooling is produced  as the rapid evaporation of the liquid refrigerant absorbs heat.</p><p>evaporite \i-'va-p3-,rlt\ Any of a variety of minerals found in sedimen�  tary deposits of soluble salts that result from the evaporation of water.  Typically, evaporite deposits occur in closed marine basins where evapo�  ration exceeds inflow. The most important such minerals include anhy�  drite, halite, calcite, gypsum, polyhalite, and potassium and magnesium  salts such as sylvite, carnallite, kainite, and kieserite.</p><p>evapotranspiration Loss of water from the soil both by evaporation  from the soil surface and by transpiration from the leaves of the plants  growing on it. Factors that affect the rate of evapotranspiration include</p><p>Dame Edith Evans as Mrs. Ross in The  Whisperers, 1967.</p><p>COURTESY OF SEVEN PINES PRODUCTIONS LTD.;  PHOTOGRAPH, PICTORIAL PARADE</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Evarts &#x25BA; evolution I 647</p><p>the amount of solar radiation, atmospheric vapor pressure, temperature,  wind, and soil moisture. Evapotranspiration accounts for most of the water  lost from the soil during the growth of a crop. Estimation of evapotrans�  piration rates is thus important in planning irrigation schemes.</p><p>Evarts \'e-vorts\, William Maxwell (b. Feb. 6, 1818, Boston, Mass.,  U.S.�d. Feb. 28, 1901, New York, N.Y.) U.S. lawyer. He served as coun�  sel for Pres. Andrew Johnson in his impeachment trial (1868). After  Johnson�s acquittal, he served as U.S. attorney general (1868-69), then  represented the U.S. in the Alabama claims arbitration at Geneva (1872).  He was Republican chief counsel in the election dispute between Ruth�  erford B. Hayes and Samuel Tilden in 1876. As Hayes�s secretary of state  (1877-81), he asserted U.S. interests over a proposed canal in Panama.  He later served in the U.S. Senate (1885-91).</p><p>Evelyn Vev-tan, 'ev-lonV, John (b. Oct. 31, 1620, Wotton, Surrey,  Eng.�d. Feb. 27, 1706, Wotton) British writer. A country gentleman from  a wealthy landowning family, he wrote some 30 books on the fine arts,  forestry, and religious topics. His Diary (published 1818), which he kept  from 1631 to 1706, is an invaluable source of information on 17th-century  social, cultural, religious, and political life. His Life of Mrs. Godolphin  (published 1847) is one of the most moving of 17th-century biographies.</p><p>evening grosbeak North American grosbeak ( Hesperiphona vesper-  tina) that is brown, yellow, black, and white. Like all other grosbeaks, it  has a large conical bill. It eats seeds and tends to form loose flocks in  flight.</p><p>evening primrose Any of various species of herbaceous plants of the  genus Oenothera (family Onagraceae). They are noted for their showy  flowers, especially the yellow-flowered biennial O. biennis, which is  found widely throughout North America and and has been introduced to  Europe. It has been grown by geneticists to determine certain principles  of heredity. The true primrose belongs to the family Primulaceae.</p><p>Evenk See Siberian peoples</p><p>event horizon Boundary marking the limits of a black hole. At the event  horizon, the escape velocity is equal to the speed of light. Since general  relativity states that nothing can travel faster than the speed of light, noth�  ing inside the event horizon can ever cross the boundary and escape  beyond it, including light. Thus, nothing that enters a black hole can get  out or can be observed from outside the event horizon. Likewise, any  radiation generated inside the horizon can never escape beyond it. For a  nonrotating black hole, the Schwarzschild radius delimits a spherical event  horizon. Rotating black holes have distorted, nonspherical event horizons.  Since the event horizon is not a material surface but rather merely a math�  ematically defined demarcation boundary, nothing prevents matter or  radiation from entering a black hole, only from exiting one. Though black  holes themselves may not radiate energy, electromagnetic radiation and  matter particles may be radiated from just outside the event horizon via  Hawking radiation.</p><p>Everest, Mount Tibetan Chomolungma \,cho-m6-Tur]-m3\ Nepali  Sagarmatha Peak on the crest of the Himalayas, southern Asia. The  highest point on Earth, with a summit at 29,035 ft (8,850 m), it lies on  the border between Nepal and Tibet (China). Numerous attempts to climb  Everest were made from 1921; the summit was finally reached by Edmund  Hillary of New Zealand and Tenzing Norgay of Nepal in 1953. In dispute  is whether the English explorer George Mallory, whose body was dis�  covered below Everest�s peak in 1999, had actually reached the peak ear�  lier, in 1924, and was descending it when he died. The formerly accepted  elevation of 29,028 ft (8,848 m), established in the early 1950s, was  recalculated in the late 1990s.</p><p>Everglades Subtropical saw-grass marsh region, southern Florida, U.S.  Covering about 4,000 sq mi (10,000 sq km), the area has water moving  slowly through it from the lip of Lake Okeechobee to mangrove swamps  bordering the Gulf of Mexico and Florida Bay. Everglades National Park,  established in 1934, encompasses the southwestern portion of the marsh,  covering 2,354 sq mi (6,097 sq km). The largest subtropical wilderness  left in the continental U.S., it has a mild climate, which provides an envi�  ronment for myriad birds, alligators, snakes, and turtles. A large portion  of the glades has been reclaimed by drainage canals, altering the habitats  of many species.</p><p>evergreen Any plant that retains its leaves through the winter and into  the following summer or through several years. Many tropical species of</p><p>broad-leaved flowering plants are evergreen, but in cold-temperate and  Arctic areas the evergreens commonly are cone-bearing shrubs or trees  (conifers), such as pines and firs. The leaves of evergreens usually are  thicker and more leathery than those of deciduous trees and often are  needlelike or scalelike in cone-bearing trees. A leaf (or needle) may  remain on an evergreen tree for two years or longer and may fall during  any season.</p><p>everlasting Any of several plants that retain their form and colour  when dried and are used in dry bouquets and flower arrangements. Popu�  lar everlastings include several species of the composite family, especially  the true everlastings, or immortelles, species of the genus Helichrysum,  native to North Africa, Crete, and the parts of Asia bordering on the  Mediterranean and cultivated in many parts of Europe. One of the best-  known everlastings is the strawflower ( H. bracteatum ) of Australia. Many  GRASSes with showy plumes or spikes are classified as everlastings.</p><p>ever-normal granaries Price-stabilizing granaries first established  in the 1st century bc. Under the Qing dynasty they were set up by all Chi�  nese provinces in each county to keep grain on hand to offset regional  food shortages in years of crop failure. By keeping the supply of grain  stable (�ever normal�), the granaries stabilized prices, and even undevel�  oped regions of the country were protected from famine.</p><p>Evers Ve-verzV Med gar (Wiley) (b. July 2, 1925, Decatur, Miss.,  U.S.�d. June 12, 1963, Philadelphia, Miss.) African American civil-  rights activist. After serving in World War II he entered business in Mis�  sissippi. He and his elder brother, Charles, began organizing local affiliates  of the NAACP; in 1954 Medgar became the organization�s first field sec�  retary in Mississippi. He traveled throughout the state recruiting members  and organizing economic boycotts. In June 1963, hours after a speech on  civil rights by Pres. John F. Kennedy, Evers was shot and killed in an  ambush outside his home. A white segregationist was charged with the  murder but was set free after two trials in 1964 resulted in hung juries;  he was finally convicted after a third trial in 1994. Evers�s widow, Myr-  lie Evers-Williams, later headed the NAACP (1995-98).</p><p>Evert, Chris(tine Marie) formerly Chris Evert Lloyd (b. Dec. 21,  1954, Fort Lauderdale, Fla., U.S.) U.S. tennis player. She became in 1971  the youngest player to reach the semifinals of the U.S. championship. She  won the U.S. Open women�s singles six times (1975-78, 1980, 1982) and  repeatedly won the Wimbledon singles (1974, 1976, 1981), the French  Open singles (1974, 1975, 1979, 1980, 1983, 1985, 1986), and the Aus�  tralian Open singles (1982, 1984), for a total of 18 grand-slam titles. She  retired in 1989.</p><p>evidence In law, something (e.g., testimony, documents, or physical  objects) presented at a judicial or administrative proceeding for the pur�  pose of establishing the truth or falsity of an allegation of fact. To pre�  serve legal due process and to prevent the jury from being misled, an  extensive body of rules has sprung up regarding the handling of evidence.  In the U.S., all federal and many state courts adhere to the Federal Rules  of Evidence, which covers such elements as types of evidence, admissi�  bility, relevance, competency of witnesses, confessions and admissions,  expert testimony, and authentication. Most evidence received at trial is in  the form of verbal statements of witnesses, who are subject to question�  ing by attorneys from both sides. Two important categories of evidence  are direct evidence, which is offered by a witness whose knowledge of a  factual matter is firsthand (as through sight or hearing), and circumstan�  tial evidence. See also exclusionary rule.</p><p>evil eye Superstition holding that a glance can cause injury or death to  those on whom it falls. The belief was found in ancient Greece and Rome  as well as in folk cultures around the world, and it has persisted into mod�  ern times. Children and animals are believed to be particularly vulner�  able. The evil eye is often thought to stem from envy and malice toward  prosperity and beauty, and thus in many cultures unguarded praise of  one�s possessions or children is thought to invite misfortune. Safeguards  include amulets, charms, and sacred texts; in Asia children may have their  faces blackened for protection.</p><p>Evita See Eva Peron</p><p>evolution Biological theory that animals and plants have their origin in  other preexisting types and that the distinguishable differences are due to  modifications in successive generations. It is one of the keystones of  modern biological theory. In 1858 Charles Darwin and Alfred Russel Wal�  lace jointly published a paper on evolution. The next year Darwin pre-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>648 I Evripos Strait &#x25BA; executive</p><p>sented his major treatise On the Origin of Species by Means of Natural  Selection, which revolutionized all later biological study. The heart of  Darwinian evolution is the mechanism of natural selection. Surviving indi�  viduals, which vary (see variation) in some way that enables them to live  longer and reproduce, pass on their advantage to succeeding generations.  In 1937 Theodosius Dobzhansky applied Mendelian genetics (see Gregor  Mendel) to Darwinian theory, contributing to a new understanding of evo�  lution as the cumulative action of natural selection on small genetic varia�  tions in whole populations. Part of the proof of evolution is in the fossil  record, which shows a succession of gradually changing forms leading up  to those known today. Structural similarities and similarities in embry�  onic development among living forms also point to common ancestry.  Molecular biology (especially the study of genes and proteins) provides  the most detailed evidence of evolutionary change. Though the theory of  evolution is accepted by nearly the entire scientific community, it has  sparked much controversy from Darwin�s time to the present; many of  the objections have come from religious leaders and thinkers (see cre�  ationism) who believe that elements of the theory conflict with literal  interpretations of the Bible.

Nov. 18, 1743, Copenhagen, Den.�d.  March 17, 1781, Copenhagen) Danish poet and dramatist. By age 19 he  was becoming known as a writer. At 30, addicted to alcohol, he adopted  a more solitary life and began producing his mature works, including The  Death of Balder (1774), in which he became the first Danish poet to use  themes from Scandinavian myth and saga. Of his dramatic works, only the  operetta Fiskerne (1779; �The Fishermen�) is still performed. He is espe�  cially known for his great personal odes and for songs such as �King  Christian Stood by the Lofty Mast,� used as a national anthem, and �Lille  Gunver,� the first Danish romance. He is considered one of Denmark�s  greatest lyric poets. His memoirs (published 1804) are his greatest prose  work.</p><p>Ewe \'a-wa\ Peoples of southeastern Ghana, southern Benin, and south�  ern Togo. They speak dialects of Gbe, a Kwa language of the Niger-Congo  family. The Ewe never formed a single centralized state, remaining a col�  lection of independent communities that made temporary alliances in time  of war. Most Ewe are farmers; some coastal Ewe fish. Spinning, weav�  ing, pottery making, and blacksmithing are important crafts. They num�  ber more than 3.5 million.</p><p>Ewing Vyii-iqV (William) Maurice (b. May 12, 1906, Lockney,  Texas, U.S.�d. May 4, 1974, Galveston, Texas) U.S. geophysicist. He  taught many years at Columbia University (1944-74) and also directed  the Lamont-Doherty Geological Observatory (1949-74). Studying the  structure of the Earth�s crust and mantle, he made seismic refraction mea�  surements in the Atlantic basins, along the Mid-Atlantic Ridge, and in the  Mediterranean and Norwegian seas. In 1935 he took the first seismic  measurements in open seas. He was among those who proposed that  earthquakes are associated with the central oceanic rifts that encircle the  globe, suggesting that seafloor spreading may be worldwide and episodic  in nature. In 1939 he took the first deep-sea photographs.</p><p>excavation In archaeology, the exposure, recording, and recovery of  buried material remains. The techniques employed vary by the type of  site, but all forms of archaeological excavation require great skill and  careful preparation. The process begins with site location, by means of  aerial photography, remote sensing, or, commonly, accidental discovery  by construction crews. This step is followed by surveying and mapping,  site sampling, and developing an excavation plan. The design and execu�  tion of an excavation frequently require an interdisciplinary team of  experts. The actual digging consists of the removal of surplus dirt and the  painstaking examination, through observation, sifting, and other means,  of remaining soil, artifacts, and context. Common dig tools include the  trowel, penknife, and brush. The excavation phase is followed by artifact  classification, analysis, dating, and the publication of results. Excavation  may last decades or be a short-term emergency salvage operation (as when  a site is threatened by development).</p><p>exchange, bill of See bill of exchange</p><p>exchange control Governmental restrictions on private transactions  in foreign money or claims on foreign money. Residents are required to</p><p>sell foreign money coming into their possession to a central bank or spe�  cialized government agency at exchange rates set by the government. The  chief function of most systems of exchange control is to maintain a favour�  able BALANCE OF PAYMENTS. See also FOREIGN EXCHANGE.</p><p>exchange rate Price of one country�s money in relation to another�s.  Exchange rates may be fixed or flexible. An exchange rate is fixed when  two countries agree to maintain a fixed rate through the use of monetary  policy. Historically, the most famous fixed exchange-rate system was the  gold standard; in the late 1850s, one ounce of gold was defined as being  worth 20 U.S dollars and 4 pounds sterling, resulting in an exchange rate  of 5 dollars per pound. An exchange rate is flexible, or �floating,� when  two countries agree to let international market forces determine the rate  through supply and demand. The rate will fluctuate with a country�s exports  and imports. Most world trade currently takes place with flexible  exchange rates that fluctuate within relatively fixed limits. See also  EXCHANGE CONTROL, FOREIGN EXCHANGE.</p><p>Exchequer \iks-'che-kar, 'eks-.che-korV English government department  responsible for receiving and dispersing public revenue. It was established  by Henry I in the 12th century, and its name refers to the checkered cloth  on which the reckoning of revenues took place. Originally, the lower  Exchequer was an office for the receipt and payment of money, while the  upper Exchequer was a court sitting twice a year to regulate accounts.  The English judicial system grew out of the upper Exchequer, and the  lower Exchequer became the Treasury. �Exchequer� is still the unofficial  name of the Treasury in Britain.</p><p>excitation Addition of a discrete amount of energy to a system that  changes it usually from a state of lowest energy (ground state) to one of  higher energy (excited state). For example, in a hydrogen atom, an exci�  tation energy of 10.2 electron volts is required to move the lone electron  from its ground state to its first excited state. The excitation energy stored  in excited atoms and nuclei is usually emitted as ultraviolet radiation from  atoms and as gamma radiation (see gamma ray) from nuclei as they return  to their ground states.</p><p>exclusionary rule In U.S. law, the principle that evidence seized by  police in violation of the constitutional protection against unreasonable  search and seizure may not be used against a criminal defendant at trial.  The Supreme Court of the United States established the validity of the rule  in Weeks v. U.S. (1914). In Wolf v. Colorado (1949) the court limited  application of the rule to the federal courts; this decision was overturned  in Mapp v. Ohio (1961), which required the rule to be applied universally.  In the 1980s the court allowed an exception to the rule, holding that evi�  dence obtained �in good faith� with a search warrant later ruled invalid  is admissible.</p><p>excommunication Form of censure by which a member of a religious  body is excluded from the congregation of believers and from the rites  of the church. Excommunication has been used in various religions, nota�  bly Christianity, as a punishment for grave offenses such as heresy. In  Roman Catholicism an excommunicated person is barred from receiving  the sacraments and from burial in consecrated ground. The offender may  be absolved by a priest (in some cases, only by a bishop or the pope) and  received back into the church after confessing his or her sin and doing  penance for it. In Protestant denominations other terms, such as �church  discipline,� may be attached to essentially the same censure. Although  now seldom used, the practice of herein in Judaism was a form of excom�  munication that excluded people from the community for prescribed times  or forbade them from hearing the Torah. The term is also applied to the  expulsion of Buddhist monks from the sangha.</p><p>excretion Bodily process for disposing of undigested food waste prod�  ucts and nitrogenous by-products of metabolism, regulating water content,  maintaining acid-base balance, and controlling osmotic pressure to pro�  mote homeostasis. It refers to both urination and defecation and to the pro�  cesses that take place in the digestive and urinary systems, as the kidney and  liver filter wastes, toxins, and drugs from the blood and food reaches the  last stage of digestion. Ammonia from protein digestion, the primary  excretory product, is converted to urea to be excreted in urine.</p><p>executive In politics, a person or persons constituting the branch of  government charged with executing or carrying out the laws and appoint�  ing officials, formulating and instituting foreign policy, and providing  diplomatic representation.

In Judaism and  Christianity, it has been used extensively in the study of the Bible. Textual  criticism tries to establish the accuracy of biblical texts. Philological criti�  cism deals with grammar, vocabulary, and style in pursuit of faithful  translation. Literary criticism classifies texts according to style and  attempts to establish authorship, date, and audience. Tradition criticism  seeks the sources of biblical materials and traces their development.  Redaction criticism examines the way pieces of the tradition have been  assembled into a literary composition by editors. Form criticism studies  the way narratives are shaped by the cultures that produce them. Histori�  cal criticism looks at a text�s historical context.</p><p>Exekias \ek-'sek-yos\ (fl. c. 540-520 bc, Greece) Greek potter. He was  the most famous of the black-figure vase painters (see black-figure pot�  tery). His name is found on 13 surviving vases. He is known for his elegant  drawing; his greatest gift was for conveying pathos and insight rather than  overt action. Some 40 unsigned vases are attributed to him on stylistic  grounds. He also made clay plaques designed to decorate tombs.</p><p>exercise Training of the body to improve health and fitness. Different  types have different purposes, including aerobics for heart and respiratory  function and weight loss, weight-bearing exercise for bone strength,  weight training for muscle strength, and stretching for flexibility. Specific  exercises are used in physical medicine and rehabilitation. Benefits include  lower blood pressure, higher HDL cholesterol, improved disease resistance,  and better general well-being.</p><p>Exeter \'ek-sa-tar\ ancient Isca Dumnoniorum City and adminis�  trative district (pop., 2001: 111,078), administrative and historic county  of Devon, England. The county town (seat) of Devon, it is located on the  River Exe about 10 mi (16 km) above the English Channel and commands  an important river crossing. An early British tribe, the Dumnonii, made  Exeter their centre; when it was taken by the Romans, they named it Isca  Dumnoniorum. The main town in southwestern England during the  Middle Ages, Exeter was subjected to a number of sieges. Alfred the Great  twice held it against the Danes (877 and c. 894); the Danes finally took  the city in 1003 but lost it in 1068 to William I (the Conqueror). Exeter�s  Norman cathedral, consecrated in 1133, houses the Exeter Book, the larg�  est collection extant of Old English poetry. The city has light manufactur�  ing and is a service centre for an extensive region.</p><p>existentialism Philosophical movement oriented toward two major  themes, the analysis of human existence and the centrality of human  choice. Existentialism�s chief theoretical energies are thus devoted to  questions about ontology and decision. It traces its roots to the writings  of Soren Kierkegaard and Friedrich Nietzsche. As a philosophy of human  existence, existentialism found its best 20th-century exponent in Karl Jas�  pers; as a philosophy of human decision, its foremost representative was  Jean-Paul Sartre. Sartre finds the essence of human existence in  freedom�in the duty of self-determination and the freedom of choice�  and therefore spends much time describing the human tendency toward  �bad faith,� reflected in humanity�s perverse attempts to deny its own  responsibility and flee from the truth of its inescapable freedom.</p><p>Exmouth Gulf Inlet of the Indian Ocean, Western Australia. Located  between North West Cape and the mainland, the gulf is 55 mi (90 km) long  and 30 mi (48 km) across the mouth. Fishing, pearling, prawning, and tour�  ism are the main local industries. Nearby Cape Range National Park is  important for the conservation of the rare yellow-footed rock wallaby.</p><p>Exodus Second book of the Old Testament. The title refers to the depar�  ture of the Israelites from Egypt under Moses in the 13th century bc. The  book begins with the story of the Israelites� enslavement in Egypt and  God�s call to Moses to become a prophet. It tells of the plagues sent to  persuade the pharaoh to free the Israelites, and it recalls their crossing of  the Sea of Reeds (or the Red Sea) and their 40 years of wandering in the  Sinai desert. It also recounts how God made a covenant with Israel at  Mount Sinai, handing down the Ten Commandments. In Exodus God estab�  lishes his reliability as Israel�s protector and savior, and lays claim to its  loyalty and obedience.</p><p>exogamy and endogamy \ek-'sa-g3-me...en-'da-g9-me\ Practices  controlling the relation of the sexes in the selection of marital partners.  Exogamous groups require their members to marry outside the group,</p><p>sometimes even specifying the group into which members must marry.  Such groups are usually defined in terms of kinship rather than politics or  territory. Exogamy is usually characteristic of unilineal descent groups, in  which descent is reckoned either patrilineally or matrilineally. In endoga-  mous groups, marriage outside one�s group may be forbidden, or there  may merely be a tendency to marry within the group. Endogamy is char�  acteristic of aristocracies and religious and ethnic minorities in industri�  alized societies but also of the caste system in India and of class-conscious  nonliterate societies such as the Masai of East Africa.</p><p>exorcism In Christianity, a ceremony used to drive demons out of a per�  son they have possessed. Jesus healed people tormented by evil spirits,  casting them out with a word, and his followers later drove out demons  �in his name.� By the 3rd century this task was assigned to a specially  trained class of lower clergy. Rituals for exorcism of people and places  also exist in many other traditions.</p><p>expanding universe Current understanding of the state of the uni�  verse. It is based on the finding that all galaxies are moving away from  each other. Application of general relativity to cosmology, along with the  detection of redshifted light coming from galaxies outside the Milky Way  Galaxy, led to the realization in the 1920s that all galaxies are receding  (see Edwin Hubble). It is unknown whether the universe will expand indefi�  nitely (open universe) or eventually collapse (closed universe) into an  extremely dense, congested state, as it began, according to the big-bang  model. See also Friedmann universe.</p><p>experimental psychology Branch or type of psychology concerned  with employing empirical principles and procedures in the study of psy�  chological phenomena. The experimental psychologist seeks to carry out  tests under controlled conditions in order to discover an unknown effect  or law, to examine or establish a hypothesis, or to illustrate a known law.  The areas of study that rely most heavily on the experimental method  include those of sensation and perception, learning and memory, motivation,  and physiological psychology. Experimental approaches are also used in  CHILD PSYCHOLOGY, CLINICAL PSYCHOLOGY, EDUCATIONAL PSYCHOLOGY, and SOCIAL PSY�  CHOLOGY.</p><p>experimentalism See instrumentalism</p><p>expert system Computer-based system designed to respond like a  human expert in a given field. Expert systems are built on knowledge  gathered from human experts, analogous to a database but containing rules  that may be applied to solving a specific problem. An interface allows the  user to specify symptoms and to clarify a problem by responding to ques�  tions posed by the system. Software tools exist to help designers build a  special-purpose expert system with minimal effort. An outgrowth of work  in artificial intelligence, expert systems show promise for an ever-widening  range of applications. There are now widely used expert systems in the  fields of medicine, personnel screening, and education.</p><p>explanation In philosophy, set of statements that makes intelligible  the existence or occurrence of an object, event, or state of affairs. Among  the most common forms of explanation are causal explanation (see cau�  sation), deductive-nomological explanation (see covering-law model),  which involves subsuming the explanandum under a generalization from  which it may be derived in a deductive argument (e.g., �All gases expand  when heated; this gas was heated; therefore, this gas expanded�) and sta�  tistical explanation, which involves subsuming the explanandum under a  generalization that gives it inductive support (e.g., �Most people who use  tobacco contract cancer; this person used tobacco; therefore, this person  contracted cancer�). Explanations of human behaviour typically appeal to  the subject�s beliefs and desires, as well as other facts about him, and  proceed on the assumption that the behaviour in question is rational (at  least to a minimum degree). Thus an explanation of why the subject  removed his coat might cite the fact that the subject felt hot, that the sub�  ject desired to feel cooler, and that the subject believed that he would feel  cooler if he took off his coat.</p><p>Explorer Any of the largest (55-member) series of unmanned U.S.  spacecraft, launched between 1958 and 1975. Explorer 1, the first satellite  sent into orbit by the U.S., discovered the innermost Van Allen radiation  belt. Other notable craft in this series include Explorer 38 (1968), which  measured galactic radio sources and studied low radio frequencies in  space, and Explorer 53 (SAS 3; 1975), which investigated X-ray and  gamma-ray sources within and beyond the Milky Way Galaxy.

Mechanical explosives,  which depend on a physical reaction (e.g., overloading a container with  compressed air until it bursts), are little used except in mining. Nuclear  explosives (see nuclear weapon) use either nuclear fission or nuclear fusion.  Chemical explosives are of two types: detonating (high) explosives (e.g.,  TNT, dynamite) have extremely rapid decomposition and development of  high pressure; deflagrating (low) explosives (e.g., black powder, smoke�  less powder; see gunpowder) merely burn quickly and produce relatively  low pressure. Primary detonating explosives are ignited by a flame, a  spark, or an impact; secondary ones require a detonator and sometimes a  booster. Modern high explosives use either mixtures of ammonium nitrate  and fuel oil or ammonium nitrate-based water gels.</p><p>exponential function In mathematics, a function in which a constant  base is raised to a variable power. Exponential functions are used to model  changes in population size, in the spread of diseases, and in the growth  of investments. They can also accurately predict types of decline typified  by radioactive decay (see half-life). The essence of exponential growth,  and a characteristic of all exponential growth functions, is that they double  in size over regular intervals. The most important exponential function is  e x , the inverse of the natural logarithmic function (see logarithm).</p><p>Export-Import Bank of the United States (Ex-lm Bank) One</p><p>of the principal U.S. government agencies in international finance. Origi�  nally incorporated as the Export-Import Bank of Washington in 1934, its  goal is to help finance U.S. exports, principally by lending money to for�  eign buyers of U.S. goods and services. Such assistance often consists of  credits to foreign banks and governments in connection with development  projects. See also development bank.</p><p>Expressionism In the visual arts, artistic style in which the artist  depicts not objective reality but the subjective emotions that objects or  events arouse. This aim is accomplished through the distortion and exag�  geration of shape and the vivid or violent application of colour. Its roots  are found in the works of Vincent van Gogh, Edvard Munch, and James  Ensor. In 1905 the movement took hold with a group of German artists  known as Die Brucke; their works influenced such artists as Georges  Rouault, Chaim Soutine, Max Beckmann, Kathe Kollwitz, and Ernst Barlach.  The group of artists known as Der Blaue Reiter were also considered  Expressionists. Expressionism was the dominant style in Germany after  World War I; postwar Expressionists included George Grosz and Otto  Dix. Its emotional qualities were adopted by other 20th-century art move�  ments. See also Abstract Expressionism.</p><p>extenuating circumstance or mitigating circumstance In</p><p>law, circumstance that diminishes the culpability of one who has com�  mitted a criminal offense. In many Anglo-American legal systems, provo�  cation of the accused by the victim can reduce a charge of first-degree  murder to second-degree murder or to manslaughter. In Britain, a charge</p><p>of murder may be reduced to manslaughter if the accused is found to be  suffering diminished capacity (see diminished responsibility). The Italian  penal code allows consideration of motives of honour. Extenuating cir�  cumstances also are a factor in many civil actions.</p><p>extinction (of species) Dying out or termination of a species. It  occurs when a species can no longer reproduce at replacement levels.  Most past extinctions are thought to have resulted from environmental  changes that the doomed species was either unable to adapt to or that  caused it to adapt so thoroughly that it became a distinctly new species.  The effect of humans on the environment, through hunting, collecting,  and habitat destruction, has become the principal factor in plant and ani�  mal extinctions.</p><p>extortion Unlawful exaction of money or property through intimida�  tion or undue exercise of authority. It may include threats of physical  harm, criminal prosecution, or public exposure. Some forms of threat,  especially those made in writing, are occasionally singled out for sepa�  rate statutory treatment as blackmail. See also bribery.</p><p>extradition Process by which one state, at the request of another,  returns a person for trial for a crime punishable by the laws of the request�  ing state and committed outside the state of refuge. Extradition is regu�  lated within countries by extradition acts and between countries by  treaties. Some principles of extradition are common to many countries.  Most decline to surrender their own nationals. Countries also generally  recognize the right of political asylum. In view of the solidarity of nations  in the repression of crime, however, countries are usually willing to coop�  erate in bringing criminals to justice.</p><p>extrasensory perception (ESP) Perception that involves awareness  of information about something (such as a person or event) not gained  through the senses and not deducible from previous experience. Classic  forms of ESP include telepathy, clairvoyance, and precognition. No con�  clusive demonstrations of the existence of ESP in any individual have  been given, but popular belief in the phenomenon remains widespread,  and people who claim to possess ESP are sometimes employed by inves�  tigative teams searching for missing persons or things.

Covering an area of 16,075 sq mi  (41,634 sq km), it encompasses the southwestern provinces of Caceres  and Badajoz. Its capital is Merida. During the Christian reconquest of the  Iberian Peninsula, the name Extremadura was used to refer to the zones  outside of Moorish territory. From the late Middle Ages the term was  applied to an area approximating the modern region. The countryside  remains partitioned into latifundios (large estates); wheat, grapes, and  olives are important crops.</p><p>extreme sports Sports events characterized by high speed or high risk.  Such sports include aggressive inline skating, wakeboarding, street luge,  skateboarding, and freestyle bicycle events (wherein tricks such as back  flips are performed on a bicycle). Many of the events�snowboarding,  skateboarding, and freestyle biking are examples�are performed on  ramps and inclines or in a halfpipe, some with walls as high as 50 feet,  which allows the athletes to get air, or achieve the height necessary to,  for example, rotate on a bicycle. Many of these sports were made popu�  lar� by the X Games (championship competitions sponsored by the cable-  television network ESPN). The 1998 and 2002 Olympic Games featured  extreme snowboarding events in a halfpipe, in which boarders performed  jumps, rotations, and mid-air maneuvers.</p><p>extrusion Process in which metal or other material is forced through a  series of dies to create desired shapes. Many ceramics are manufactured by  extrusion, because the process allows efficient, continuous production. In  a commercial screw-type extruder, a screw auger continuously forces the  plastic feed material through an orifice or die, resulting in simple shapes  such as cylindrical rods and pipes, rectangular solid and hollow bars, and  long plates. In metalworking, extrusion converts a billet of metal into a  length of uniform cross-section by forcing the billet through the orifice  of a die; aluminum is easily extruded. Formed sheet aluminum is used for  opaque curtain-wall panels and window frames.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>extrusive rock &#x25BA; Ezra I 651</p><p>extrusive rock Any igneous rock derived from magma that is poured  out or ejected at the Earth�s surface.

Exxon Mobil engages in every phase of the  petroleum industry from oil fields to service stations. Both Exxon and  Mobil had their origins in Standard Oil (see Standard Oil Co. and Trust)  and were founded in the late 1800s. In 1926 the New Jersey subsidiary  of Standard Oil, Exxon�s predecessor, introduced the Esso brand name.  The name was changed to Exxon in 1972. As of 2002 Exxon Mobil was  the world�s largest integrated oil company.</p><p>Eyasi \a-'ya-se. Lake Lake, northern Tanzania. At an elevation of about  3,400 ft (1,040 m), the lake covers an area of about 400 sq mi (1,050 sq km)  and occupies the bottom of a bowl-like depression. Its walls are purple  lava, enclosing a broad expanse of white alkaline shallows. Flamingos  inhabit the lakeshore in vast flocks. Hominid fossils were found nearby.</p><p>Eybeschutz \1-ba- I shffits\ # Jonathan (b. c. 1690, Krakow, Pol.�d.  1764, Altona, Den.) Polish rabbi and Talmudic scholar. He served as rabbi  in a number of European towns, and his scholarship gained him a loyal  following. He was reputed to have mystic powers; when the women of  his congregation asked him to give them protection from death in child�  birth, he offered them amulets that contained a prayer to the false mes-  siah Shabbetai Tzevi. A prominent German rabbi, Jacob Emden (1697-  1776), denounced the amulets. The dispute that ensued between Emden  and Eybeschutz divided the European Jewish community.</p><p>Eyck \'ik\, Jan van (b. before 1395, Maaseik, Bishopric of Liege, Holy  Roman Empire�d. before July 9, 1441, Bruges) Flemish painter. He is  recorded in 1422 as a master painter working for John of Bavaria, count of  Holland, and later was employed by Philip III the Good, duke of Burgundy.  Securely attributed paintings survive only from the last decade of his  career; 10 are signed and dated, an unusually large number for the period.  He produced portraits and religious subjects that are unmatched for their  technical brilliance, their intellectual complexity, and the richness of their  symbolism; he perfected the newly developed technique of oil painting.  His masterpiece is the Adoration of the Lamb (1432), known as the Ghent  Altarpiece, which he painted with his brother Hubert (c. 1370-1426). He is  commonly regarded as the greatest northern European artist of the 15th  century. His works were widely copied and avidly collected.</p><p>eye Organ that receives light and visual images. Non-image forming, or  direction, eyes are found among worms, mollusks, cnidarians, echino-  derms, and other invertebrates; image-forming eyes are found in certain  mollusks, most arthropods, and nearly all vertebrates. Arthropods are  unique in possessing a compound eye, which results in their seeing a  multiple image that is partially integrated in the brain. Lower vertebrates  such as fish have eyes on either side of the head, allowing a maximum  view of the surroundings but producing two separate fields of vision. In  predatory birds and mammals, binocular vision became more important.  Evolutionary changes in the placement of the eyes permitted a larger  overlap of the two visual fields, resulting in the higher mammals in a par�  allel line of direct sight. The human eye is roughly spherical. Light passes  through its transparent front and stimulates receptor cells on the retina  (cones for colour vision, rods for black-and-white vision in faint light),  which in turn send impulses through the optic nerve to the brain. Vision  disorders include near- and farsightedness and astigmatism (correctable  with eyeglasses or CONTACT LENSes), colour blindness, and night blindness.  Other eye disorders (including detached retina and glaucoma) can cause  VISUAL-FIELD DEFECTS Or BLINDNESS. See also OPHTHALMOLOGY; PHOTORECEPTION. See  illustration opposite.</p><p>eyeglasses Lenses set in frames to wear in front of the eyes to aid vision  or correct vision defects (see ophthalmology, optometry). Their use for far�  sightedness and nearsightedness has been known since the late Middle  Ages. In 1784 Benjamin Franklin invented bifocals, with divided lenses for</p><p>distant and near vision. Eyeglasses can also correct astigmatism. Most  lenses are made of glass or plastic (lighter and more shatterproof than  glass but easily scratched). Sunglass lenses are tinted to reduce glare and  often treated to reduce ultraviolet light exposure. See also contact lens.</p><p>Eyre Peninsula Large promontory, South Australia. Projecting into the  Indian Ocean, the peninsula is about 200 mi (320 km) long and lies  between the Great Australian Bight and Spencer Gulf.

With a total area  of 3,700 sq mi (9,600 sq km), Lake Eyre is the lowest point in Australia,  50 ft (15 m) below sea level. The lake consists of two sections: Lake Eyre  North, 90 mi (144 km) long and 40 mi (65 km) wide, is joined by the  narrow Goyder Channel to Lake Eyre South, which is 40 mi (65 km) long  and about 15 mi (24 km) wide. Lake Eyre is normally dry, and it fills  completely only (on average) twice a century. When filled, the lake takes  about two years to dry up again. The region is within Lake Eyre National  Park.</p><p>Ezekiel \i-'zek-yal\ (fl. 6th century bc) Priest and prophet of ancient  Israel. He was the subject and partial author of the biblical book of Ezek�  iel. He began to prophesy to the Jews in Palestine c. 592 bc, pronounc�  ing God�s judgment on a sinful nation. He witnessed the conquest of  Jerusalem by Babylon and saw his fellow Israelites taken away into cap�  tivity.

He served as a commissioner of the Persian government,  which was tolerant of other religions but required order and authority. His  efforts led to a restoration of traditional worship in the rebuilt Temple of  Jerusalem and the dissolution of all mixed marriages. For creating a Jew�  ish community based on the Law, which could exist without political  statehood, he is often considered the founder of modern Judaism.

The outer portion consists of the white protective sclera  and transparent cornea, through which light enters. The middle layer includes the  blood-supplying choroid and pigmented iris. Light passing into the interior through  the pupil is regulated by muscles that control the pupil's size. The retina comprises  the third layer and contains receptor cells (rods and cones) that transform light  waves into nervous impulses. The lens, lying directly behind the iris, focuses light  onto the retina. The macula lutea, in the centre of the retina, is a region of high  visual acuity and colour discrimination. Nerve fibres pass out through the optic  nerve to the brain's visual centre. The eye's anterior and posterior chambers con�  tain a watery fluid that nourishes the cornea and lens. The vitreous humour helps  maintain the eye's shape. A thin layer of mucous membrane (conjunctiva) protects  the eye's exposed surface. External muscles, including the medial rectus and lateral  rectus muscles, connect and move the eye in its socket.</p><p>� MERRIAM-WEBSTER INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>652 I F-15 &#x25BA; fact-value distinction</p><p>F-15 or Eagle Twin-engine jet fighter built by the Boeing Company.

Educated in  Europe and England, he took over his father�s jewelry business in St.  Petersburg in 1870. The objects he designed quickly won him the patron�  age of European and Russian royalty. Specializing in gold, silver, mala�  chite, jade, lapis lazuli, and gemstones, he manufactured not only  conventional jewelry but objects of fantasy, much of it inspired by the  decorative arts of the Louis XVI style.

His workshops were shut down after the  1917 revolution, and he died in exile.</p><p>Fabian Society Vfa-be-9n\ Socialist society founded in 1883-84 in  London, to establish a democratic socialist state in Britain. The name  derived from Fabius Maximus Cunctator, whose elusive tactics in avoiding  pitched battles led to victory over stronger forces. Fabians believed in  evolutionary socialism rather than revolution, and used public meetings  and lectures, research, and publishing to educate the public. Important  early members included George Bernard Shaw and Sidney and Beatrice  Webb.

Elected  dictator in 217, he used a strategy of harassment and attrition in the Second  Punic War against Hannibal (218-201). These cautious delaying tactics  (Cunctator means �delayer�) allowed Rome to recover and take the offen�  sive, but Roman impatience led to defeat at the Battle of Cannae.

Unlike a folktale, it has a moral that is woven into the story and often  explicitly formulated at the end. The Western fable tradition began with  tales ascribed to Aesop. It flourished in the Middle Ages, reached a high  point in 17th-century France in the works of Jean de La Fontaine, and found  a new audience in the 19th century with the rise of children�s literature.

Particular types  included the fabula Atellana, the earliest form of native farce in ancient  Italy; the fabula crepidata, a form of Roman tragedy based on Greek  models; the fabula palliata, an ancient Roman comedy based on Greek  New Comedy and treating a Greek subject; the fabula praetexta, an ancient  Roman drama with a theme from Roman history or legend; and the fab�  ula togata, a Romancomedy based on Greek models but featuring Roman  life and dress.</p><p>face Front part of the head, extending from the forehead to the chin and  housing the eyes, nose, mouth, and jaws. The receding of the jaw and the  increasing size of the brain in human evolution has made the face essen�  tially vertical, with two distinctively human features: a prominent, pro�  jecting nose and a clearly defined chin. The face and braincase follow  different patterns of growth. While the face grows more slowly, it ends  up much larger compared to the braincase in adults than at birth. The facial  muscles move the features to express emotion.</p><p>fact-value distinction In philosophy, the ontological distinction  between what is (facts) and what ought to be (values). David Hume gave</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>factor &#x25BA; Fairbairn I 653</p><p>the distinction its classical formulation in his dictum that it is impossible  to derive an �ought� from an �is.� See also naturalistic fallacy.</p><p>factor In multiplication, one of two or more numerical or algebraic  components of a product. A whole number�s factors are the whole num�  bers that divide evenly into it (e.g., 1, 2, 3, 4, 6, and 12 are factors of 12).  To factor a counting number means to break it down into its prime number  factors. To factor a polynomial is to find its prime polynomial factors, a  basic procedure for solving algebraic equations. According to the funda�  mental theorem of arithmetic, the prime factorization of any number or  polynomial is unique.</p><p>factorial For any whole number, the product of all the counting numbers  up to and including itself. It is indicated with an exclamation point: 4! (read  �four factorial�) is 1 x 2 x 3 x 4 = 24. In order for certain formulas involv�  ing permutations and combinations to work, 0! is defined to be 1. Factorials  are particularly useful in calculating the number of ways an event can  occur, for example, the number of possible orders of finish in a race.</p><p>factoring In finance, the selling of accounts receivable on a contract basis  to an agency known as a factor in order to obtain cash payment before  the accounts come due. The factor assumes full responsibility for credit  analysis of new accounts, payments collection, and credit losses. Factor�  ing is most often used in seasonal industries such as textiles and shoes to  shift the functions of credit and collection to a specialized agency.</p><p>factory Structure in which work is organized to meet the need for pro�  duction on a large scale usually with power-driven machinery. In the 17th-  18th century, the domestic system of work in Europe began giving way to  larger units of production, and capital became available for investment in  industrial enterprises. The movement of population from country to city  also contributed to change in work methods. Mass production, which trans�  formed the organization of work, came about by the development of the  machine-tool industry. With precision equipment, large numbers of identi�  cal parts could be produced at low cost and with a small workforce. The  assembly line was first widely used in the U.S. meat-packing industry; Henry  Ford designed an automobile assembly line in 1913. By mid-1914, chassis  assembly time had fallen from \2Vi man-hours to 93 man-minutes. Some  countries, particularly in Asia and South America, began industrializing in  the 1970s and later. See also American System of manufacture.</p><p>factory farming System of modern animal farming designed to yield  the most meat, milk, and eggs in the least amount of time and space pos�  sible. The term, descriptive of standard farming practice in the U.S., is  frequently used by animal-rights activists, who maintain that animal-  protection measures routinely ignore farm animals. Animals are often fed  growth hormones, sprayed with pesticides, and fed antibiotics to mitigate  the problems of infestation and disease that are exacerbated by crowded  living conditions. Chickens spend their lives crowded into small cages,  often so tightly that they cannot turn around; the cages are stacked in high  batteries, and the length of �day� and �night� are artificially controlled to  maximize egg laying. Veal calves are virtually immobilized in narrow  stalls for their entire lives. These and numerous other practices have long  been decried by critics.</p><p>Fadlallah Uad-'bl-bV (Ayatollah Sayyid) Muhammad  Husayn (b. c. 1935, Al-Najaf, Iraq) Muslim Shl'ite cleric associated  with Lebanese Hezbollah organization. He was schooled at a traditional  madrasah in his birthplace, where he studied under many of the eminent  ShTite scholars of his day. His scholarly acumen eventually earned him  the honourific ayatollah. He moved to Lebanon (where his parents were  bom) in 1966 and quickly established a reputation as a leading religious  authority. Fadlallah�s eloquence led many to believe that he was Hezbol�  lah�s leader after the party was founded in 1982, but both he and the party  have denied any direct link, while acknowledging his strong spiritual  influence over the organization. Though impressed by the Islamic revo�  lution in Iran (1979), he generally stood aloof from the more radical posi�  tion of its leader, Ruhollah Khomeini.</p><p>Faenza majolica Nfa-'en-za-mo-'ja-li-koX Tin-glazed earthenware pro�  duced in the Italian city of Faenza from the late 14th century. Early Faenza  jugs were decorated in green and purple with Gothic lettering and heral�  dic lions; the first major majolica piece is a wall plaque dated 1475. In the  15th century, Renaissance motifs appeared in dark blue, rich orange, and  copper-green; vases with a peacock-feather design and a globular two-  handled jar are characteristic of Faenza. The factory�s most outstanding  wares date from the late 15th to the mid-16th century. See also faience.</p><p>Faeroe Islands See Faroe Islands</p><p>Fahrenheit, Daniel (Gabriel) (b.

He spent most of his life in the Netherlands, where he  devoted himself to the study of physics and the manufacture of precision  meteorological instruments. He is best known for inventing a successful  alcohol thermometer (1709) and mercury thermometer (1714) and for  developing the Fahrenheit temperature scale, setting zero at the freezing  point of an equal mixture of ice and salt. He discovered that water can  remain liquid below its freezing point and that the boiling point of liq�  uids varies with atmospheric pressure.</p><p>Faidherbe \fe-'derb\, Louis (-Leon-Cesar) (b. June 3, 1818, Lille,  Fr.�d. Sept. 29, 1889, Paris) Governor of French Senegal (1854-61,  1863-65) and a founder of France�s colonial empire in Africa. Faidherbe  was trained as a military engineer and served in Algeria and Senegal  before becoming the colonial governor of Senegal. Alarmed by the grow�  ing power of the Islamic leader 'Umar Tal, he took the offensive, driving  off 'Umar Tal, subjugating the Moorish tribes in the north, and transform�  ing his colony into the region�s dominant power. In 1857 he founded the  capital city of Dakar.</p><p>faience \fa-'ans, fi-'a n s\ Tin-glazed earthenware made in France, Ger�  many, Spain, and Scandinavia, simi�  lar to Faenza majolica, for which it  was named. The term is also applied  to glazed earthenware made in  ancient Egypt, where it was used for  beads, amulets, jewelry, and small  animal and human figures, most  notably the blue-glazed hippopota�  mus figures of the Middle Kingdom  (c. 2000-c. 1670 bc). Faience tiles,  first made in the early dynasties,  were used to decorate the walls of  the subterranean chambers of the  pyramids. In the New Kingdom (c.</p><p>1550-c. 1070 bc), polychrome tiles  with floral designs were used in  houses and palaces.</p><p>fair Temporary market where buyers  and sellers gather to transact busi�  ness. Fairs are held at regular inter�  vals, generally at the same location  and time of year. An important form of commerce before the Industrial  Revolution, fairs solved the problem of distribution and made possible the  demonstration of arts and crafts and the sale and barter of goods. They  were a fixture of the Roman Empire and medieval Europe, where they  were held at major caravan crossroads and near religious festivals. The  rules of the fairs eventually became the basis of European business law.  Fairs began to die out as cities grew larger and transportation networks  became more extensive, though some continued to exist as religious fes�  tivals or recreational events. County, agricultural, and livestock fairs are  still held in many countries. The trade fair or trade show, often an inter�  national event in which exhibitors from one industry display their goods,  gained popularity in the 20th century.</p><p>fair trade law In the U.S., any law allowing manufacturers of brand-  name or trademarked goods to fix the actual or minimum resale prices of  these goods. (Elsewhere the practice is called price maintenance.) Fair  trade laws were passed by many states during the Great Depression in an  effort to protect independent retailers from price-cutting by large chain  stores and consequent loss of employment in distributive trades, but most  were later repealed at the state level. Critics argued that such laws  restricted competition; the complexity of post-World War II marketing  channels also made enforcement impracticable. In 1975 the few that  remained in existence were repealed by an act of Congress.</p><p>Fairbairn Vfer-.bernX, Sir William (b. Feb. 19, 1789, Kelso, Rox�  burghshire, Scot.�d.

Founded in 1902 after  a gold strike, it was named for Charles W. Fairbanks. As the northern  terminus of the Alaska Highway and the railroad, it is the main supply  centre for the northern Alaskan oil business (see Trans-Alaska Pipeline).  Located nearby are Fort Wainwright, Eielson Air Force Base, and the  University of Alaska, Fairbanks (1917). Fairbanks is the site of the annual  800-mi (1,290-km) Yukon Marathon boat race and the North American  Championship Sled Dog Races.</p><p>Fairbanks, Douglas orig. Douglas Elton Ulman (b. May 23,</p><p>1883, Denver, Colo., U.S.�d. Dec. 12, 1939, Santa Monica, Calif.) U.S.  film actor. Fairbanks was a Broadway star by 1910, noted for his exuber�  ance and physical agility. Fie made his film debut in The Lamb (1915).  As cofounder of United Artists (1919), he produced and starred in such  films as The Mark ofZorro (1920), Robin Hood (1922), and The Thief of  Baghdad (1924). His films were so popular that he was called the �King  of Hollywood� in the 1920s. His 15-year marriage to Mary Pickford ended  in 1935. Douglas Fairbanks, Jr. (b. Dec. 9, 1909, New York, N.Y.,  U.S.�d. May 7, 2000, New York City), Fairbanks�s son by his first wife,  was a debonair leading man in U.S. and British films, including Cathe�  rine the Great (1934), The Prisoner of Zenda (1937), and State Secret  (1950). In the 1960s he hosted and sometimes acted in the British TV  drama series Douglas Fairbanks Presents.</p><p>Fairchild, David (Grandison) (b. April 7, 1869, Lansing, Mich.,  U.S.�d.

From 1904  to 1928, as head of the section of plant pathology of the U.S. Department  of Agriculture, he supervised the introduction of many useful plants into  the U.S., including alfalfa, dates, mangoes, horseradish, and bamboos.</p><p>Fairfax (of Cameron), Thomas Fairfax, 3rd Baron (b. Jan. 17,  1612, Denton, Yorkshire, Eng.�d. Nov. 12, 1671, Nun Appleton, York�  shire) Commander in chief of the Parliamentary army during the English  Civil Wars. His tactical skill and courage helped bring about many Parlia�  mentary victories, including the Battle of Marston Moor. As commander  in chief of the New Model Army, he defeated Charles I at the Battle of  Naseby. Fairfax disapproved of the purge of Parliament by his soldiers in  1648 and refused to serve on the commission that condemned Charles to  death. In 1650 he resigned as commander in chief to protest the proposed  invasion of Scotland. In 1658 he helped George Monck restore Parliamen�  tary rule in the face of opposition from the army. He was a member of the  Parliament that invited Charles�s son to return to England as Charles II.</p><p>Fairweather, Mount Mountain, British Columbia, Canada It is  located on the Alaska border in the Fairweather Range of the St. Elias  Mountains, at the southwestern end of the Glacier Bay National Park. The  highest peak in the province, it reaches 15,299 ft (4,663 m). It was named  by Capt. James Cook, who saw the peak in 1778 while navigating the bay  in �fair weather.�</p><p>fairy In folklore, any of a race of supernatural beings who have magic  powers and sometimes meddle in human affairs. Some have been  described as of human size, while others are �little people� only a few  inches high. The term was first used in medieval Europe. Fairy lore is  especially common in Ireland, Cornwall, Wales, and Scotland. Though  usually beneficent in modern children�s stories, the fairies of the past were  powerful and sometimes dangerous beings who could be friendly, mis�  chievous, or cruel, depending on  their whim. Fairies were thought to  be beautiful, to live much longer  than human beings, and to lack souls.</p><p>They sometimes carried off human  infants and left changelings as sub�  stitutes. They occasionally took  human lovers, but to enter fairyland  was perilous for humans, who were  obliged to remain forever if they ate  or drank there.

They live  in freshwater ponds in Europe, Central Asia, western North America, the  drier regions of Africa, and Australia. See also shrimp.</p><p>fairy tale Simple narrative typically of folk origin dealing with super�  natural beings. Fairy tales may be written or told for the amusement of  children or may have a more sophisticated narrative containing super�  natural or obviously improbable events, scenes, and personages and often  having a whimsical, satirical, or moralistic character. The term embraces  popular folktales such as �Cinderella� and �Puss in Boots,� as well as art  fairy tales of later invention, such as those by Hans Christian Andersen. It  is often difficult to distinguish between tales of literary and oral origin,  because folktales have received literary treatment from early times, and  literary tales can often be traced back to oral tradition.</p><p>Faisalabad Vfi-so-b-.bad \ formerly (until 1979) Lyallpur VlIl-.purN  City (pop., 1998: 1,977,246) and district, Punjab province, Pakistan.

A distributing centre  located in the central Punjab plain, its industries produce chemicals and  synthetics, textiles, and food products. It is the site of West Pakistan Agri�  cultural University (1961 and of a number of colleges affiliated with the  University of the Punjab.</p><p>faith healing Curing of an illness or disability by recourse to divine  power, without the use of traditional medicine. A healer such as a clergy  member or an inspired layperson may act as intermediary. Certain places,  such as the grotto at Lourdes, France, are believed to effect cures among  believers. In ancient Greece, temples honoring the god of medicine, Ascle-  PlUS, were built near springs with healing waters. In Christianity, support  for faith healing is based on the miraculous cures wrought by Jesus dur�  ing his ministry. Christian Science is noted for faith healing, and it is also  practiced in a more dramatic way in Pentecostalism through such customs  as the laying on of hands.</p><p>Fakhr al-DTn al-RazT Vfa-ksr-al-'den-ar-'ra-zeV (b. 1149, Rayy,  Iran�d. 1209, near Herat, Khwarezm) Islamic scholar and theologian.  He traveled widely before settling in Herat (in modern Afghanistan). The  author of more than 100 books (on subjects as diverse as medicine, min�  eralogy, and grammar), he gained fame and wealth through his scholar�  ship and skill in debate, in which he often presented unorthodox views  fully and favorably before refuting them. Though this led to accusations  of heresy, it has preserved information about little-known sects. His works  include one of the major commentaries on the Qur�an, The Keys to the  Unknown (or The Great Commentary), and Collection of the Opinions of  Ancients and Moderns, a classic of kalam. His bad temper earned him  many enemies, and he may have been poisoned to death.</p><p>Falange \fa-'lan-ha,\ English Vfa-lanj\ (Spanish: �Phalanx�) Extreme  nationalist political group in Spain. Founded in 1933 by Jose Antonio  Primo de Rivera and influenced by Italian fascism, the Falange gained popu�  larity in opposition to the Popular Front government of 1936. Gen. Fran�  cisco Franco merged the group with other right-wing factions by decree  in 1937 and became the Falange�s absolute chief. 150,000 Falangists  served in Franco�s armed forces in the Spanish Civil War. After their vic�  tory, the Falange�s fascism was subordinated to the Franco regime�s con�  servative values. On Franco�s death in 1975 a law was passed permitting  other �political associations,� and the Falange was abolished in 1977.</p><p>Falasha Vfo-Ta-shoX Jewish Ethiopians. The Falasha call themselves  House of Israel and claim descent from Menilek I, son of King Solomon  and the Queen of Sheba. Probably descended from local Agew peoples  converted by Jews in southern Arabia, they remained faithful to Judaism  after the Ethiopian kingdom was converted to Christianity in the 4th cen�  tury ad. Persecuted by Christians, they settled in the area around Lake  Tana in northern Ethiopia. Though ignorant of the Talmud, members  adhered strictly to the Mosaic law and observed some festivals of Juda�  ism. In 1975 the Israeli rabbinate affirmed that Falashas were Jews, and  from 1980 to 1992 some 45,000 Falasha emigrated to Israel, leaving  probably only a few thousand in Ethiopia.</p><p>falcon Any of nearly 60 species of diurnal birds of prey in the family  Falconidae, characterized by long, pointed wings and swift, powerful  flight.

After being apprenticed to  a carpenter, he studied sculpture in Paris. He developed an intimate style  with a taste for erotic figures. Through Madame de Pompadour�s influ�  ence, he became director of the Sevres porcelain factory (1757-66), and  many of his figures were reproduced in Sevres biscuit ware. From 1766  to 1778 he worked in Russia; his masterpiece, the colossal equestrian  statue of Peter I the Great in St. Petersburg (made famous as The Bronze  Horseman by Aleksandr Pushkin), was unveiled in 1782. After suffering a  stroke (1783), he gave up sculpture and devoted his time to writing. He  is best known for adapting the classical style of the French Baroque period  to the Rococo style ideal.</p><p>falconry Sport of employing falcons or other hawks in hunting game.  Falconry has been practiced in the Middle East at least since the 8th cen�  tury bc. It flourished among the privileged classes in Europe in the Middle  Ages. It began to die out after the advent of the shotgun and the enclo�  sure of open lands in the 17th century, but there was a renewed interest  in the sport beginning in the 1970s; there are many hawking clubs and  falconry associations. The bird most commonly used is the peregrine fal�  con, though the goshawk and sparrow hawk have also been used. Birds  are caught wild or raised from birth. Training involves selective use of a  leather hood (called a rafter) and leg thongs (jesses) to keep the animal  under control while familiarizing it with its new environment. During the  hunt the trained bird is released to bring down its prey; it then returns to  the hawker or is collected at the kill site.</p><p>Faldo, Nick (b.

Located about 300 mi (480 km) northeast of the south�  ern tip of South America, the Falklands are made up of two main islands,  East Falkland and West Falkland, and about 200 smaller islands. The  islands are spread out over some 4,700 sq mi (12,200 sq km). The capi�  tal is Stanley, on East Falkland. The population is English-speaking and  of British descent. The economy is based on sheep raising. The French  founded the islands� first settlement, on East Falkland in 1764, and the  British settled West Falkland in 1765. In 1770 the Spanish purchased the  French settlement and expelled the British, but the latter�s settlement was  restored in 1771. In 1820 Argentina proclaimed its sovereignty over the  Falklands, but the British took them back in 1833. Argentina invaded in  1982, and the British reclaimed the islands after a brief conflict (see Falk�  land Islands War).</p><p>Falkland Islands War or Malvinas War (1982) Brief but unde�  clared war between Argentina and Great Britain over control of the Falk�  land Islands (Islas Malvinas) and associated island dependencies. Both  countries long had claimed sovereignty over the Falklands and had been  in protracted negotiations over them. On April 2, 1982, Argentina�s mili�  tary government, impatient with the negotiations, occupied the islands  with some 10,000 troops. British prime minister Margaret Thatcher  responded by sending a naval task force to the region, and within three  months British forces had defeated the Argentines and reoccupied the  islands. Britain lost about 250 men, and Argentina about 700. Argentina�s  defeat discredited its military government and helped lead to the resto�  ration of civilian rule in 1983.</p><p>Fall, Albert Bacon (b. Nov. 26, 1861, Frankfort, Ky., U.S.�d.

He served in the  U.S. Senate from 1913 to 1921, when he was appointed Secretary of the  Interior by Pres. Warren G. Harding. He resigned his cabinet post two  years later and returned to New Mexico. In 1924 a Senate investigation  revealed that Fall had accepted a large bribe to lease to private oil inter�  ests, without competitive bidding, naval oil reserve lands in the Teapot  Dome reserve in Wyoming and other reserves in California. He was con�</p><p>victed of bribery in 1929 and served nine months of a one-year prison  sentence. See also Teapot Dome scandal.</p><p>Falla \'fa-yo\, Manuel de (b. Nov. 23, 1876, Cadiz, Spain�d. Nov.  14, 1946, Alta Gracia, Arg.) Spanish composer. He studied with Felipe  Pedrell and conceived a powerful musical nationalism. His first major  work was the opera La vida breve (1905). He lived in Paris (1907-14),  where he absorbed the music of Claude Debussy, Maurice Ravel, and oth�  ers. The intensely Spanish ballet El amor brujo (1915) gained him fur�  ther acclaim. The Spanish Civil War caused him to leave Spain for  Argentina c. 1938, and he never returned. His other works include Nights  in the Gardens of Spain (1915), The Three-Cornered Hat (1919), the pup�  pet opera El retablo de maese Pedro (1923; with Federico Garcia Lorca),  a harpsichord concerto (1926), and the huge unfinished oratorio  L 'Atldntida. He is regarded as the greatest Spanish composer of the 20th  century.</p><p>fallacy, formal and informal In philosophy, reasoning that fails to  establish its conclusion because of deficiencies in form or wording. For�  mal fallacies are types of deductive argument that instantiate an invalid  inference pattern (see deduction; validity); an example is �affirming the  consequent: If A then B; B; therefore. A.� Informal fallacies are types of  inductive argument the premises of which fail to establish the conclusion  because of their content. There are many kinds of informal fallacy;  examples include argumentum ad hominem (�argument against the man�),  which consists of attacking the arguer instead of his argument; the fallacy  of false cause, which consists of arguing from the premise that one event  precedes another to the conclusion that the first event is the cause of the  second; the fallacy of composition, which consists of arguing from the  premise that a part of a thing has a certain property to the conclusion that  the thing itself has that property; and the fallacy of equivocation, which  consists of arguing from a premise in which a term is used in one sense  to a conclusion in which the term is used in another sense.</p><p>Fallen Timbers, Battle of (Aug. 20, 1794) Decisive victory of U.S.  Gen.

Oct. 9, 1562, Padua) Italian anatomist. He contributed  greatly to knowledge of the ear and reproductive system. His observa�  tions of the dissection of cadavers are outlined in Observationes anatom-  icae (1561). He discovered the fallopian tubes, which connect the ovaries  to the uterus, and several major nerves of the head and face. He described  the semicircular canals in the ear and named the vagina, placenta, clito�  ris, palate, and cochlea. He and Andreas Vesalius overturned many of  Galen�s principles, a development essential to Renaissance medicine.</p><p>fallout Descent of radioactive materials from the atmosphere to the  earth. Radioactivity in the atmosphere may arise from natural causes such  as cosmic rays as well as from nuclear explosions and atomic reactor  operations. The explosion of nuclear weapons leads to three types of fall�  out: local, tropospheric, and stratospheric. The first, intense but relatively  short-lived, occurs as larger radioactive particles are deposited near the  site of the explosion. Tropospheric fallout occurs when the finer particles  enter the troposphere, and it spreads over a larger area in the month after  the explosion. Stratospheric fallout, made of fine particles in the strato�  sphere, may continue years after the explosion, and the distribution is  nearly worldwide. Many different radioisotopes are formed during a  nuclear explosion, but only long-lived isotopes (e.g., cesium- 137,  strontium-90) are deposited as stratospheric fallout.</p><p>Falloux Law \fa-Tii\ (1850) Act granting legal status to independent  secondary schools in France.

The collection was intended to protect the rights  of diocesan bishops against encroachment by their metropolitan superi�  ors and to protect the clergy from lay interference. The decretals also  emphasized the authority of the pope at the expense of that of the arch�  bishops. They consist of laws, papal letters, and decrees of councils�  some genuine but many (including the famous Donation of Constantine)  forgeries. Widely accepted by the end of the 10th century, the collection  was not proved a hoax until the 17th century.</p><p>falsework or centering Temporary framework used during construc�  tion to support arches and similar structures while the mortar or concrete  is setting or the steel is being joined.

It was founded  in China in 1992 by Li Hongzhi, a former grain-bureau clerk from Jilin  province. He originally registered it as a form of the natural-healing dis�  cipline qigong , but he later withdrew it from China�s Qigong Research  Association to stress its spiritual (rather than health-related) emphasis. Its  members nevertheless claim great health benefits from its practice. It  claims a worldwide following of 100 million, with 70 million in China;  Chinese authorities claim it has as few as 2 or 3 million members. The  movement has been regarded as a threat by the Chinese government,  which started arresting its followers in mid-1999. Many Falun Gong mem�  bers were later tried and given long prison sentences. Li emigrated to the  U.S. in 1998.</p><p>Falwell Vfol-.welV, Jerry L. (b. 1933, Lynchburg, Va., U.S.) Protestant  evangelist. An engineering student before turning to religion, he founded  Thomas Road Baptist Church in 1956 and later Liberty Baptist College.  His Old-Time Gospel Hour television show serves as outreach for his  church. In 1979 he organized the Moral Majority to encourage his fol�  lowers to become involved in politics; he withdrew from its leadership  in 1990 to return to preaching. A fundamentalist interpreter of the Bible,  he is known for his sometimes extreme conservatism.</p><p>Familist Vfa-mo-lisA Member of the Family of Love religious sect. It  was founded by a 16th-century Dutch merchant, Hendrik Niclaes, whose  goal was to end religious wrangling and unite all �lovers of truth� in one  great Christian fellowship of peace. His largest following was in England,  where his works were privately published. Elizabeth I issued a proclama�  tion against the Family of Love in 1580. The sect died out after the res�  toration of the English monarchy in 1660; some of its members may have  joined the Society of Friends.</p><p>family Basic social unit consisting of persons united by ties of marriage  (affinity), �blood� (consanguinity), or adoption and usually representing  a single household. The essence of the family group is the parent-child  relationship, whose outlines vary widely among cultures. One prominent  familial form is the nuclear family, consisting of the marital pair living  with their offspring in a separate dwelling. While some scholars believe  this to be the oldest form, others point to the inconclusive prehistorical  record and the widespread existence of other forms such as the polygy-  nous family (a husband, two or more wives, and their offspring) and the  extended family (including at least parents, married children, and their  offspring). The family as an institution provides for the rearing and social�  ization of children, the care of the aged, sick, or disabled, the legitima�  tion of procreation, and the regulation of sexual conduct in addition to  supplying basic physical, economic, and emotional security for its mem�  bers. See also adoption; marriage.</p><p>family In pedology, a group of soils that have similar profiles and include  one or more subdivisions called series. The primary characteristics that  define each of the nearly 6,600 identified soil families are the physical  and chemical properties�especially texture, mineral composition, tem�  perature, and depth�that are important for the growth of plants.</p><p>family planning Use of measures designed to regulate the number  and spacing of children within a family, largely to curb population growth  and ensure each family�s access to limited resources. The first attempts  to offer family planning services began with private groups and often  aroused strong opposition. Activists such as Margaret Sanger in the U.S.,  Marie Stopes in England, and Dhanvanthis Rama Rau in India eventually  succeeded in establishing clinics for family planning and health care.</p><p>Today many countries have established national policies and encourage  the use of public family services. The United Nations and the World Health  Organization offer technical assistance. See also birth control.</p><p>family practice or family medicine or general practice Field  of medicine that stresses comprehensive primary health care, emphasiz�  ing the family unit. Practitioners must be familiar to some degree with  medical specialties and, especially in health maintenance organizations,  are now often gatekeepers who refer patients to specialists when neces�  sary. Once virtually the only kind of medicine, family practice has been  defined as a separate field only since increasing specialization in medi�  cine led to a shortage of practitioners. A 1963 World Health Organization  report stressing the need for medical education to focus on the patient as  a whole throughout life led to specific programs in family practice.</p><p>family sagas See Icelanders' sagas</p><p>famine Extreme and protracted shortage of food, resulting in wide�  spread hunger and a substantial increase in the death rate. General fam�  ines affect all classes or groups in the region of food shortage; class  famines affect some classes or groups much more severely than others;  regional famines affect only a particular region of a country. Causes may  be natural or human. Natural causes include drought, flooding, unfavour�  able weather conditions, plant disease, and insect infestation. The chief  human cause is war; others include overpopulation, bad distribution sys�  tems, and high food prices. Several severe famines occurred in the 20th  century, including those in China (1928-29, 5-10 million dead; 1958-62,  up to 20 million), Russia (1921-22, 1.25-5 million; 1932-34, 6-8 mil�  lion), India (1943-44, 1.5 million), Cambodia (1975-79, 1 million), and  sub-Saharan Africa.</p><p>fan Rigid or folding handheld device used for cooling, air circulation,  or ceremony or as a sartorial accessory throughout the world from ancient  times. As evidenced by Egyptian reliefs, early fans were of the rigid type,  with a handle or stick attached to a rigid leaf or to feathers. In China, the  folding fan came into fashion during the Ming dynasty (1368-1644);  much significance came to be attached to the fan in East Asia, and many  great Chinese painters devoted their talents to fan decoration. Portuguese  traders in the 15th century brought fans to Europe from China and Japan.  Through the 19th century in the West, fan decoration and size varied with  European fashion.</p><p>Fan Chung-yen See Fan Zhongyen</p><p>Fan Zhongyen Vfan-'juq-'ysiA or Fan Chung-yen (b. 989, Wu,  Jiangsu province, China�d. 1052, China) Chinese scholar-reformer  whose reforms anticipated those of Wang Anshi.

Elected to Italy�s constituent assembly (1946), he became secretary-  general of the Christian Democratic Party (1954) after serving briefly as  premier. With his party�s victory in 1958, he became premier (1958-59)  and stressed social reforms. Buoyed by widespread public reaction against  rising neofascist activity, he was returned to the premiership (1960-63)  and again promoted a reformist program. He gained Italy�s election to the  UN Security Council (1958) and served as president of the UN General  Assembly in 1965.

In 1960 he was appointed ambassador to Ghana by the rebel  provisional government. His widely read book The Wretched of the Earth  (1961) urged colonized peoples to purge themselves of their degradation  in a �collective catharsis� to be achieved through violence against Euro�  pean oppressors. He died of leukemia at age 36.</p><p>fantasia \fan-'ta-zh9, .fan-to-'ze-oX Musical composition free in form  and inspiration, often for an instrumental soloist. Most fantasias try to  convey the impression of improvisation. The first were Italian works for  lute (c. 1530). Keyboard fantasias became common in the late 16th cen�  tury; both organ and harpsichord fantasias flourished in the 17th and 18th  centuries in Britain, Germany, and France. Fugal, imitative texture, some�  times highly learned in character, was common from the beginning, often  alternating with running passagework and highly chromatic chordal pas�  sages in free rhythms. Ensemble fantasias were widely composed as well.</p><p>fantasy Mental images or imaginary narratives that distort or entirely  depart from reality. Primary fantasies arise spontaneously from the uncon�  scious, while secondary fantasies are consciously summoned and pursued.  Sigmund Freud saw fantasy as a vehicle for the expression of repressed  desires (see repression). Fantasy is important in the lives of children and  is a vital element in play. In adult life it is crucial to creative thinking and  the making of art. Fantasy can become destructive if it serves as a con�  stant refuge from the world of reality and a source of delusions.</p><p>Fa rite or Fanti \'fan-te\ Second largest segment of the Akan peoples of  the southern coast of Ghana. The Fante speak a language of the Kwa group  of Niger-Congo languages. As intermediaries in colonial-era trade  between the Asante to the north and the Europeans to the south, the Fante  established several independent kingdoms that formed a confederacy in  the late 17th century. The confederacy aided the British in wars against  the Asante in the 19th century but was disbanded in 1873 under British  pressure. The Akan peoples all together make up about half of the popu�  lation of Ghana. An important Fante organization called the asafo began  as a military group, but in contemporary society it serves mostly politi�  cal, social, and religious functions.</p><p>Fante \fan-'te\, John (b.

Wait Until Spring, Bandini (1938), was followed by his best-known book,  Ask the Dust (1939), the first of his novels set in Depression-era Califor�  nia. Other books included the story collection Dago Red (1940) and the  novels Full of Life (1952) and Brotherhood of the Grape (1977). He also  wrote numerous screenplays, including Creature from the Black Lagoon  (1954), Full of Life (1956), and A Walk on the Wild Side (1962).

Though he associated  with progressive artists (Gustave  Courbet, Eugene Delacroix, Edouard  Manet), he was a traditionalist best  known for his portraits and still lifes  with flowers. His portrait groups,  reminiscent of 17th-century Dutch  guild portraits, depict literary and</p><p>artistic persons of the time; his flower paintings were especially popular in  England, thanks to James McNeill Whistler and John Everett Millais, who  found patrons to support him. His later years were devoted to lithography.</p><p>Farabi \fa-'ra-be\, al- in full Muhammad ibn Muhammad ibn  Tarkhan ibn Uzalagh al-Farabl Latin Alpharabius or Aven-  nasar (b. c. 878, Turkistan�d. c. 950, Damascus?) A logician and one of  the great philosophers of medieval Islam. He was probably the son of one  of the caliph�s Turkish bodyguards, and he grew up in Baghdad. From 942  he resided at the court of Prince Sayf al-Dawlah. Greatly influenced by  Baghdad�s Greek heritage in philosophy, especially the writings of Aris�  totle, he was known as the Second Teacher or the Second Aristotle. He used  Artistotle�s ideas in his proof of the existence of God and was influenced  also by Neoplatonic ideas and Sufi mysticism. Like Plato, he believed it  was the philosopher�s task to provide guidance to the state. He wrote more  than 100 works, notably The Ideas of the Citizens of the Virtuous City.</p><p>Faraday, Michael (b. Sept. 22, 1791, Newington, Surrey, Eng.�d.  Aug. 25, 1867, Hampton Court) English physicist and chemist. Son of a  blacksmith, he received only a basic education in a church Sunday school,  but he went to work as an assistant to Humphry Davy, from whom he  learned chemistry. He discovered a number of new organic compounds,  including benzene, and was the first to liquefy a �permanent� gas. His  major contributions were in the fields of electricity and magnetism. He  was the first to report induction of an electric current from a magnetic  field. He invented the first electric motor and dynamo, demonstrated the  relation between electricity and chemical bonding, discovered the effect  of magnetism on light, and discovered and named diamagnetism. He also  provided the experimental, and much of the theoretical, foundation on  which James Clerk Maxwell built his electromagnetic field theory. In 1833  he was appointed professor at the Royal Institution. After 1855 he retired  to a house provided by Queen Victoria, but he declined a knighthood.</p><p>Farah, Nuruddin (b. 1945, Baidoa, Italian Somaliland) Somali writer,  Somalia�s first novelist and first English-language author.

His other works include  a trilogy� Sweet and Sour Milk (1979), Sardines (1981), and Close  Sesame (1983)�about life under an African dictatorship. Maps (1986)  examines identity and boundaries. The political nature of his fiction forced  him into exile, and he taught in Europe, North America, and elsewhere  in Africa.</p><p>farce Light, dramatic composition that uses highly improbable situa�  tions, stereotyped characters, violent horseplay, and broad humour.

Renowned for his vocal power and  remarkable agility, he was persuaded by Porpora to go to London in 1734,  where he became the greatest opera star of his time. In 1747 he aban�  doned the public stage for the court of Philip V in Madrid, where his sing�  ing revived the ailing monarch. Farinelli took over the court�s musical  establishment and engaged in highly extravagant projects.

He was educated at the court of  Madrid, where he had been sent to prove his father�s loyalty to the Hab-  sburgs. In 1578 Philip II appointed him governor-general of the Nether�  lands, where his mother, Margaret of Parma, had been regent earlier. His  great achievement was the restoration of Spanish rule in the southern  provinces and perpetuation of Roman Catholicism there. He succeeded  by astute statesmanship and military operations against the alliance of  rebellious Protestant provinces led by William the Silent. In 1586 he suc�  ceeded his father as duke of Parma and Piacenza, but he never returned  to Italy to rule.</p><p>Farnese \far-�na-sa\ family Italian family that ruled the duchy of Parma  and Piacenza from 1545 to 1731. The family became noted for its states�  men and soldiers, especially in the 14th�15th century, as well as by con�  tracting politically useful marriages. In 1545 Pope Paul III, a Farnese,  detached Parma and Piacenza from the papal dominions and made them  into duchies. The first duke was his illegitimate son, Pier Luigi Farnese  (1503�47), whose son Ottavio (1542-86), the 2nd duke, made Parma the  capital and consolidated the family�s power. The 3rd duke, Alessandro Far�  nese, was Spain�s regent of the Netherlands and duke in name only. His son,  Ranuccio I (1569-1622), and grandson, Odoardo I (1612-46), left heavy  financial and diplomatic debts by inconclusive military campaigns in the  Thirty Years' War. In 1649 Pope Innocent X accused the Farnese of the mur�  der of an ecclesiastic and seized the fief. Ranuccio II (1630-94) declared  war and was defeated, and the duchy survived precariously. Francesco Far�  nese (1678-1727) tried to save the state, but his only important success was  the marriage of his niece Isabella Farnese to Philip V of Spain (1714). In 1731  the duchy passed from the last Farnese of the male line, Antonio (1679-  1731), to Elizabeth�s son, the future Charles III.</p><p>Farnsworth, Philo T(aylor) (b.

In 1927 he successfully  transmitted the first image using electronic means. By 1930 he was per�  fecting an electronic camera tube, the Image Dissector, which he demon�  strated to rival inventor Vladimir Zworykin of Radio Corporation of  America (RCA). Through the 1930s Farnsworth engaged in lawsuits  against RCA, both sides claiming the invention of electronic television.  In 1939 RCA agreed to pay him royalties as part of a patent-licensing  agreement; that same year RCA introduced the first successful television  system. Farnsworth went on to patent many other inventions, but he never  achieved financial success or primary credit for inventing television.</p><p>faro One of the oldest gambling games played with cards.

Area: 540  sq mi (1,399 sq km). Population: (2002 est.) 47,400. Lying north of the  British Isles, the islands are politically situated within the kingdom of  Denmark. There are 17 inhabited islands and many islets and reefs. The  largest, Strpmp, holds the capital of Torshavn. The islands are high and  rugged, with coasts that are deeply indented with fjords. The economy is  based on fishing and sheep raising. First settled by Irish monks (c. 700),  the islands were colonized by the Vikings (c. 800) and were ruled by Nor�  way from the 11th century until 1380, when they passed to Denmark. They  unsuccessfully sought independence in 1946 but received self-  government in 1948.

Farouk�s administration was hampered by  internal rivalries. His alienation of the military, especially after its loss to  Israel (1948), led to his own downfall. In 1952 a coup led by Gamal Abdel  Nasser forced him to abdicate.

After Malcolm converted to Sunni Islam, Farrakhan denounced  him and replaced him as minister of Mosque No. 7 in Harlem. Farrakhan  later expressed regret at having contributed to the climate of antagonism  that preceded Malcolm�s assassination in 1965. When Warith Deen  Mohammed, Elijah Muhammad�s successor as leader of the Nation of Islam,  gradually began integrating the organization into the orthodox Muslim  community, Farrakhan broke away and formed his own organization, also  called the Nation of Islam (1978). A compelling orator whose rhetoric  often descended into overt anti-Semitism, Farrakhan was nonetheless effec�  tive in encouraging African American self-reliance and unity. He was the  main organizer of the Million Man March on Washington, D.C., in 1995.  In 2000 Farrakhan and Mohammed recognized each other as fellow Mus�  lims, and Farrakhan subsequently moved his group closer to orthodox  Islam and moderated his racial remarks.</p><p>Farrar \f3-'rar\, Geraldine (b. Feb. 28, 1882, Melrose, Mass.,  U.S.�d. March 11, 1967, Ridgefield, Conn.) U.S. soprano. She received  vocal training in New York and Paris and made her debut in Charles Gou�  nod�s Faust in 1901. Coached by Lilli Lehmann (1848-1929), she made  her Metropolitan Opera debut in 1906, performed in the American pre�  miere of Madama Butterfly opposite Enrico Caruso (1907), and was later a  celebrated Carmen. She retired in 1922. She also acted in silent films.</p><p>Farrar, Straus &amp; Giroux Vfar-3r- , straus...zhir- , u\ Publishing com�  pany in New York City noted for its literary excellence. It was founded in  1945 by John Farrar and Roger Straus as Farrar, Straus &amp; Co. After various  changes in personnel and name, it took its present name in 1964, with the  addition of Robert Giroux as editor in chief. The company became estab�  lished as a leading independent trade publisher of writers of the first rank,  including many Nobel and Pulitzer Prize winners. In 1994 a controlling  interest was sold to the German publisher Georg von Holtzbrinck.</p><p>Farrell Vfar-oL, James T(homas) (b. Feb. 27, 1904, Chicago, Ill.,  U.S.�d. Aug. 22, 1979, New York, N.Y.) U.S. novelist and short-story  writer. A native of Chicago and a graduate of the University of Chicago,  he is known for his realistic portraits of the city�s lower-middle-class Irish  population, drawn from his own experiences. His well-known Studs Loni-  gan trilogy� Young Lonigan (1932), The Young Manhood of Studs Loni-  gan (1934), and Judgment Day (1935)�traces the self-destruction of a  spiritually crippled young man. He later planned a cycle of 25 novels, of  which he completed 10. Of the 25 novels he published, The Face of Time  (1953) is among the best. He also produced 17 short-story collections.</p><p>Farrell, Suzanne orig. Roberta Sue Ficker (b. Aug. 16, 1945,  Cincinnati, Ohio, U.S.) U.S. ballet dancer. She trained at the School of  American Ballet and joined the New York City Ballet (NYCB) at age 16,  becoming a soloist at age 18. George Balanchine created roles for her in  ballets such as Meditation, Don Quixote, and Slaughter on Tenth Avenue.  After several years as principal dancer with Maurice Bejart�s Ballet of the  20th Century (1970-75), she returned to the NYCB in 1975 as principal  dancer. There she continued to create leading roles until she retired in  1989 and joined the faculty of the School of American Ballet, on which  she served until 1993. She later formed her own company, which carried  on the Balanchine tradition.</p><p>Farsi language See Persian language</p><p>fascism Vfa-.shi-zomV Philosophy of government that stresses the pri�  macy and glory of the state, unquestioning obedience to its leader, sub�  ordination of the individual will to the state�s authority, and harsh  suppression of dissent. Martial virtues are celebrated, while liberal and  democratic values are disparaged. Fascism arose during the 1920s and  �30s partly out of fear of the rising power of the working classes; it dif�  fered from contemporary communism (as practiced under Joseph Staun)  by its protection of business and landowning elites and its preservation  of class systems. The leaders of the fascist governments of Italy (1922-  43), Germany (1933^-5), and Spain (1939-75)� Benito Mussolini, Adolf  Hitler, and Francisco Franco �were portrayed to their publics as embodi�  ments of the strength and resolve necessary to rescue their nations from  political and economic chaos. Japanese fascists (1936-45) fostered belief  in the uniqueness of the Japanese spirit and taught subordination to the  state and personal sacrifice.

It can change  from one period to the next, from generation to generation. It serves as a</p><p>reflection of social and economic status, a function that explains the popu�  larity of many styles throughout costume history; in the West, courts have  been a major source of fashion. In the 19th and 20th centuries, fashion  increasingly became an profitable, international industry as a result of the  rise of world-renowned fashion houses and fashion magazines.

Britain had sought to extend its empire from Cairo to the Cape  of Good Hope, while France had sought to extend its own from Dakar to  the Sudan. A French force under Jean-Baptiste Marchand was the first to  arrive at a strategically located fort at Fashoda, soon followed by a Brit�  ish force under Lord Kitchener. After a tense standoff the French with�  drew, but they continued to press claims to other posts in the region. In  March 1899 the French and British agreed that the watershed of the Nile  and the Congo rivers should mark the frontier between their spheres of  influence.</p><p>Fassbinder Vfas-.bin-dorV, Rainer Werner (b. May 31, 1946, Bad  Worishofen, W.Ger.�d. June 10, 1982, Munich) German film director.  He was involved in the avant-garde theatre movement in Munich and  helped form the Antitheatre (1967). His first full-length film (1969) was  followed by 40 others, produced in a short period, including The Bitter  Tears of Petra von Kant (1972), Effi Briest (1974), The Marriage of Maria  Braun (1979), the 15-hour Berlin Alexanderplatz (1980), Lola (1981), and  Veronika Voss (1982). Regarded as a leader of the German New Wave,  he helped revitalize German cinema in the 1970s and �80s. His socially  and politically conscious films often explore themes of oppression and  despair.</p><p>fasteners In construction, connectors between structural members.  Bolted connections are used when it is necessary to fasten two elements  tightly together, especially to resist shear and bending, as in column and  beam connections. Threaded metal bolts are always used in conjunction  with nuts. Another threaded fastener is the screw, which has countless  applications, especially for wood construction. The wood screw carves a  mating thread in the wood, ensuring a tight fit. Pins are used to keep two  or more elements in alignment; since the pin is not threaded, it allows for  rotational movement, as in machinery parts. Riveted connections, which  resist shearing forces, were in wide use for steel construction before being  replaced by welding. The rivet, visibly prominent on older steel bridges,  is a metal pin fastener with one end flattened into a head by hammering  it through a metal gusset plate. The common nail, less resistant to shear  or pull-out forces, is useful for cabinet and finishing work, where stresses  are minimal.</p><p>fasting Abstaining from food, usually for religious or ethical reasons.  In ancient religions it was used to prepare worshipers or priests to  approach deities, to pursue a vision, to demonstrate penance for sins, or  to assuage an angered deity. All the major world religions include fasting  among their practices. Judaism has several fast days, notably Yom Kippur.  For Christians Lent is set aside as a 40-day period of penitence before  Easter, including the traditional fast days of Ash Wednesday and Good  Friday. In Islam the month of Ramadan is observed as a period of total  abstention from food from dawn to dusk. Fasting to make a political pro�  test is often referred to as a hunger strike; hunger strikes have been  employed by, among others, 19th-century female suffragists, Mohandas  K. Gandhi, and late-20th-century Irish nationalists. Moderate fasting is  also sometimes practiced for its claimed health benefits.</p><p>Fastnachtsspiel Vfast-.nakt-.shpeL Carnival or Shrovetide play that  emerged in the 15th century as the first truly secular drama of pre-  Reformation Germany. Usually performed on open-air platform stages by  amateur actors, students, and artisans, the plays mixed popular comic and  religious elements, reflecting the tastes of their predominantly bourgeois  audiences. They often contained satirical attacks on greedy clergymen and  other traditional dislikes of German burghers and are believed to have  been influenced by pre-Christian folk traditions.</p><p>fat Any organic compound of plant or animal origin that is not volatile,  does not dissolve in water, and is oily or greasy. Chemically, fats are  identical to animal and vegetable oils, consisting mainly of triglycerides  (esters of glycerol with fatty acids). Fats that are liquid at room tempera�  ture are called oils. Differences in melting temperature and physical state  depend on the saturation of the fatty acids and the length of their carbon  chains. The glycerides may have only a few different component fatty</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>660 i Fatah &#x25BA; fauna</p><p>acids or as many as 100 (in butterfat). Almost all natural fats and oils  incorporate only fatty acids that are constructed from two-carbon units  and thus contain only even numbers of carbon atoms. Natural fats such  as corn oil have small amounts of compounds besides triglycerides,  including phospholipids, plant steroids, tocopherols (vitamin E), vitamin A,  WAXes, carotenoids, and many others, including decomposition products  of these constituents. Sources of fats in foods include ripe seeds and some  fruits (e.g., corn, peanuts, olives, avocados) and animal products (e.g.,  meat, eggs, milk). Fats contain more than twice as much energy (calo�  ries) per unit of weight as proteins and carbohydrates. Digestion of fats in  foods, often partial, is earned out by enzymes called lipases. The break�  down products are absorbed from the intestine into the blood, which car�  ries microscopic fat droplets reconstituted from digested fats (or  synthesized in cells) to sites of storage or use. Fats are readily broken  down�primarily into glycerol and fatty acids�by hydrolysis, a first step  for many of their numerous industrial uses. See also lipid.</p><p>Fatah Vfat-Ti,\ English Vfa-ta\ inverted acronym of Harakat  al-Tahrlr al-Watani al-Filastlnl ("Palestine National Lib�  eration Movement") Palestinian guerrilla organization and political  party, whose name means �conquest� in Arabic. Founded by Yasir 'Arafat  and Khalil al-WazIr in the late 1950s, the movement relied on guerrilla  warfare and occasional acts of terrorism in an attempt to wrest Palestine  from Israeli control. It eventually became the largest faction within the  Palestine Liberation Organization and attacked Israeli interests worldwide.  Originally based in Damascus, it was forced to relocate several times  before a political agreement was reached with Israel in 1993. A number  of factions within Fatah rejected the goal of peace with Israel and split  from the main organization. In 1994 the Palestinian Authority was estab�  lished, and Fatah dominated the governing body for more than a decade.  In the 2006 elections for the Palestinian Legislative Council, the group  was unexpectedly defeated by the rival organization Hamas.</p><p>Fates In Greek and Roman mythology, the three goddesses who deter�  mined human destiny. The Fates were usually depicted as old women:  Clotho, the Spinner; Lachesis, the Allotter; and Atropos, the Inflexible.  Clotho spun the thread of human life, Lachesis dispensed it, and Atropos  cut the thread. They determined the length of each person�s life as well  as its share of suffering. Their Roman names were Nona, Decuma, and  Morta.</p><p>Father's Day See Mother's Day and Father's Day</p><p>fatigue In engineering, manifestation of progressive fracture in a solid  under cyclic loading, as in the case of a metal strip that ruptures after  repeated bending back and forth (see metal fatigue).

From May to October 1917, three peasant children  reported a vision of a woman who identified herself as the Lady of the  Rosary. On October 13, a crowd of about 70,000 witnessed an amazing  solar phenomenon just after the children had seen their vision. The first  national pilgrimage to the site occurred in 1927. Construction of a basilica  started in 1928; now flanked by retreat houses and hospitals, it faces a  square where many miraculous cures have been reported.</p><p>Fatimah or Fatima Yfa-ts-moN (b. c. 605, Mecca, Arabia�d. 633,  Medina) Daughter of Muhammad and the object of veneration in ShTite  Islam. In 622 she emigrated with her father from Mecca to Medina, where  she married her cousin 'Au. Their sons, Hasan and al-HusAYN ibn 'AlI, are  considered by Shl'ites to be the rightful inheritors of the tradition of  Muhammad. Fatimah�s marriage was unhappy, but she and her husband  were reconciled by the Prophet, and she cared for her father in his last  illness (632). She clashed with his successor, AbO Bakr, over property and  died a year later. Later tradition added to the majesty of her life, and the  Fatimid dynasty derived its name from hers.</p><p>Fatimid \'fa-to-m3d\ dynasty (909-1171) Isma'Ili ShTite dynasty of  North Africa and the Middle East. Its members traced their descent from  Fatimah, a daughter of the Prophet Muhammad. As Shfite Muslims, they  opposed the Sunnite caliphate of the �Abbasid dynasty, which they were  determined to supplant. From Yemen they expanded into North Africa and  Sicily, and in 909 their imam emerged to proclaim the new dynasty. The</p><p>first four Fatimid caliphs ruled from Tunisia, but the conquest of Egypt  in 969 occasioned the building of a new capital, Cairo. At its height, the  dynasty controlled Mecca and Medina, Syria, Palestine, and Africa�s Red  Sea coast. Seeking to overthrow the 'Abbasids, the Fatimids maintained  a network of missionaries and agents in 'Abbasid territories (see Assas�  sin). In 1057-59 the Fatimid caliph was briefly proclaimed in Baghdad,  the 'Abbasid capital, but Fatimid fortunes declined thereafter. Attacks by  Crusaders, Turks, and Byzantines and factionalism in the armed forces  weakened the caliphate; disputes over succession to the title of caliph led  to the dynasty�s final end, however, as many of the Asian missionaries  broke away, and the central government came to rely on non-lsma'lll  troops. The last caliph died in 1171, and the dynasty was succeeded by  the Sunnite Ayyubid dynasty.</p><p>fatty acid Organic compound that is an important component of lipids  in plants, animals, and microorganisms. Fatty acids are carboxylic acids  with a long hydrocarbon chain, usually straight, as the fourth substituent  group on the carboxyl (�COOH) group (see functional group) that makes  the molecule an acid. If the carbon-to-carbon bonds (see bonding) in that  chain are all single, the fatty acid is saturated; artificial saturation is called  hydrogenation. A fatty acid with one double bond is monounsaturated; one  with more is polyunsaturated. These are more reactive chemically. Most  unsaturated fats are liquid at room temperature, so food manufacturers  hydrogenate them to make them solid (see margarine). A high level of  saturated fatty acids in the diet raises blood cholesterol levels. A few fatty  acids have branched chains. Others (e.g., prostaglandins) contain ring  structures. Fatty acids in nature are always combined, usually with glyc�  erol as triglycerides in fats. Oleic acid (unsaturated, with 18 carbon atoms)  is almost half of human fat and is abundant in such oils as olive, palm,  and peanut. Most animals, including mammals, cannot synthesize some  unsaturated �essential� fatty acids; humans need linoleic, linolenic, and  arachidonic acids in their diet.</p><p>Faulhaber \'faul-,ha-b9r\, Michael von (b. March 5, 1869, Heiden-  feld, Bavaria�d. June 12, 1952, Munich, W.Ger.) German religious  leader and prominent opponent of the Nazis. Ordained in 1892, he was  bishop of Speyer before becoming cardinal and Munich�s archbishop. In  1923 he contributed to the failure of Adolf Hitler�s Beer Hall Putsch. Dur�  ing the Nazi regime he delivered the famous sermons later published as  Judaism, Christianity, and Germany (1934), which emphasized the Jew�  ish background of Christianity and asserted that Christian values were  fundamental to German culture. Despite attempts on his life, he vigor�  ously criticized Nazism in his sermons until the collapse of the Third  Reich. After the war he received West Germany�s highest award, the  Grand Cross of the Order of Merit.</p><p>Faulkner Vfok-norV William (Cuthbert) orig. William Cuth-  bert Falkner (b. Sept. 25, 1897, New Albany, Miss., U.S.�d. July 6,  1962, Byhalia, Miss.) U.S. writer. Faulkner dropped out of high school  and only briefly attended college. He spent most of his life in Oxford,  Miss. He is best known for his cycle of works set in fictional Yoknap-  atawpha County, which becomes an emblem of the American South and  its tragic history. His first major novel. The Sound and the Fury (1929),  was marked by radical technical experimentation, including stream of  consciousness. His American reputation, which lagged behind his Euro�  pean reputation, was boosted by As I Lay Dying (1930), Light in August  (1932), Absalom, Absalom! (1936), and Go Down, Moses (1942), which  contains the story �The Bear.� The Portable Faulkner (1946) finally  brought his work into wide circulation, and he won the Nobel Prize for  Literature in 1949. His Collected Stories (1950) won the National Book  Award. Both in the U.S. and abroad, especially in Latin America, he was  among the most influential writers of the 20th century.</p><p>fault In geology, a fracture in the rocks of the Earth�s crust, where com-  pressional or tensional forces cause the rocks on the opposite sides of the  fracture to be displaced relative to each other. Faults range in length from  a few inches to hundreds of miles, and displacement may also range from  less than an inch to hundreds of miles along the fracture surface (the fault  plane). Most, if not all, earthquakes are caused by rapid movement along  faults. Faults are common throughout the world. A well-known example  is the San Andreas Fault near the western coast of the U.S. The total  movement along this fault during the last few million years appears to  have been several miles.</p><p>fauna All the species of animals found in a particular region, period, or  special environment.

After serving in several cabinet posts, he was elected  president of France in an unexpected victory that was a rebuff - to the  political left. He opposed reopening the case of Alfred Dreyfus, the domi�  nating issue of his presidency, and his position encouraged agitation from  both left and right political factions.

He held the pres�  tigious organist positions at the  churches of Saint-Sulpice (1871-74)  and the Madeleine (1896-1905). In  1896 he also became professor of  composition at the Paris Conserva�  tory, where he taught students such  as Maurice Ravel and Nadia Bou�  langer. He served as its director  1905-20. In 1909 he accepted the  presidency of the Societe Musicale  Independante, a group of dissident  young composers. His works include  the operas Promethee (1900), Pene�  lope (1913), and Masques et berga-  masques (1919), the orchestral suite Pelleas et Melisande (1898), two  piano quartets (1879, 1886), numerous piano nocturnes and barcaroles, a  famous Requiem (1900), and many beautiful songs.</p><p>Gabriel Faure, portrait by John Singer  Sargent; in a private collection.</p><p>GIRAUDON/ART RESOURCE, NEW VORK</p><p>Fauset Vfo-s3t\, Jessie Redmon (b.

The Faustbuch (1587), a collection of tales purportedly by Faust,  told of such reputed wizards as Merlin and Albertus Magnus. It was widely  translated; an English version inspired Christopher Marlowe�s Tragicall  History of D. Faustus (1604), which emphasized Faust�s eternal damna�  tion. Magic manuals bearing Faust�s name did a brisk business; the clas�  sic Magia naturalis et innaturalis was known to Johann W. von Goethe,  who, like Gotthold Lessing, saw Faust�s pursuit of knowledge as noble;  in Goethe�s great Faust the hero is redeemed. Inspired by Goethe, many  artists took up the story, including Hector Berlioz (in the dramatic cantata  The Damnation of Faust) and Charles Gounod (in the opera Faust).</p><p>Fauvism Vfo-.vi-zomX Style of painting that flourished in France c.  1898-1908, characterized by the use of intensely vivid colour and turbu�  lent emotionalism. The dominant figure of the group was Henri Matisse;  others were Andre Derain, Maurice de Vlaminck, Raoul Dufy, Georges  Braque, and Georges Rouault. The name derives from the judgment of a  critic who visited their first exhibit in Paris (1905) and referred to the  artists disparagingly as �les fauves� (�wild beasts�). They were influenced  by the masters of Post-Impressionism, Vincent van Gogh and Paul Gauguin.  Fauvism was a transitional phase for most of the artists, who by 1908,  having renewed their interest in Paul Cezanne�s vision of order and struc�  ture, abandoned Fauvism for Cubism. Matisse alone continued on the  course he had pioneered.</p><p>favela \f3-'ve-b\ In Brazil, a slum or shantytown.

Unique to birds, feathers apparently evolved from the  scales of birds� reptilian ancestors. Like hair, feathers are made of kera�  tin, a fibrous protein. They are variously specialized for insulation, flight,  formation of body contours, display, and sensory reception. Contour feath�  ers form most of the surface of the bird, streamlining it for flight and often  waterproofing it. The basal portion may be downy and thus act as insu�  lation. The major contour feathers of the wing (remiges) and tail (rec-  trices) function in flight. Contour feathers grow in tracts (pterylae)  separated by bare areas (apteria) and develop from follicles in the skin.  Down feathers have loose-webbed barbs, all rising from the tip of a very  short shaft. Their function is insulation, and they may be found in both  pterylae and apteria in adult birds. They also constitute the first feather  coat of most young birds. Filoplumes are hairlike feathers with a few soft  barbs near the tip. They are associated with contour feathers and may be  sensory or decorative in function. Bristlelike, vaneless feathers occur  around the mouth, eyes, and nostrils of birds. Some bristles function as  eyelashes on ground-dwelling birds; bristles over the nostrils may serve  as filters. See illustration opposite.</p><p>feather star Any of the 550 living species of crinoid echinoderms (class  Crinoidea) that lack the stalk that  their relatives the sea lilies use to  attach themselves to the ocean bot�  tom. Most species have five  feathery-fringed arms. Feather stars  usually attach themselves to a sur�  face or a floating object and feed on  drifting microorganisms, trapping  them in their sticky arm grooves.</p><p>They live mainly on rocky bottoms  in shallow water. Most abundant  from the Indian Ocean to Japan, they  are also found in the Atlantic.</p><p>featherbedding Labour union  practices that require the employer to  pay for the performance of unneces�  sary work or to employ workers who  are not needed. Featherbedding provisions in labour contracts may result  from the continuation of work rules that were once efficient but that have  become obsolete. A union may insist on the continuation of such work  rules to protect the job security of its members.

In  1840^-9 there was a flowering of socialist thought begun by Charles Fou�  rier, Pierre-Joseph Proudhon, and others that fueled urban workers� discon�  tent. A major recession in 1846-47 added to popular unrest, as did the  increasing arbitrariness of King Louis-Philippe. An opposition campaign  brought police action, and crowds of students and workers gathered in the  streets and clashed with police. The king tried to appease the demonstra�  tors, but, when an army unit killed 40 of them, he abdicated rather than  face civil war.</p><p>Structures of a typical contour feather. The feather's central shaft (rachis) has a  series of paired branches (barbs) forming a flattened, usually curved surface  (vane). The barbs possess further branches (barbules) that are attached to one  another by hooks (barbicels), a structure that stiffens the vane. Some contour feath�  ers have a complex branch (aftershaft) that arises at the base of the vane and has  the appearance of a second, smaller feather. The unbranched basal section of the  rachis (calamus, or quill) is embedded in the skin at the inferior umbilicus, which  channels blood to the growing feather.</p><p>� MERRIAM-WEBSTER INC.</p><p>feces Vfe-,sez\ or excrement or stools Solid bodily waste discharged  from the colon through the anus during defecation. Normal feces are 75%  water. The rest is about 30% dead bacteria, 30% indigestible food matter,  10-20% cholesterol and other fats, 10-20% inorganic substances, and  2-3% protein. The colour and odour are produced by bacterial action on  chemical constituents. Many disorders produce abnormalities in the feces,  usually constipation or diarrhea. Bleeding in the stomach or intestines may  show up as dark red to black stools. Tests are needed to detect small  amounts (occult blood). High fat content usually indicates disease of the  pancreas or small intestine. Many diseases are spread by contamination  of food with feces of infected persons.</p><p>Fechner Vfek-nor,\ English \'fek-nor\, Gustav Theodor (b. April 19,  1801, Gross Sarchen, near Muskau, Lusatia�d. Nov. 18, 1887, Leipzig,  Ger.) German physicist and philosopher who founded the science of psy�  chophysics. He taught at the University of Leipzig (1834-40) but left  because of ill health. He developed experimental procedures, still useful  in experimental psychology, for measuring sensations in relation to the  physical magnitude of stimuli, establishing that, as physical stimulation  increases logarithmically, sensation increases arithmetically. Most impor�  tant, he devised an equation to express Weber's law. His principal scien�  tific work was Elements of Psychophysics (1860).</p><p>Federal Bureau of Investigation (FBI) Largest investigative  agency of the U.S. government. It was founded in 1908 as the Bureau of  Investigation within the U.S. Justice Department. J. Edgar Hoover served  as its director from 1924 until his death in 1972. Since 1968 the director,  who reports to the attorney general, has been appointed by the president  for a 10-year term, subject to Senate approval. The FBI employs more  than 10,000 special agents. Its responsibilities include investigating vio�  lations of federal criminal law (including in the areas of civil rights and  organized crime), collecting evidence in civil cases to which the U.S. is a  party, and providing internal security.</p><p>Federal Deposit Insurance Corp.

Estab�  lished after the bank holiday in early 1933, the FDIC was intended to  restore public confidence in the system. It insures bank deposits in eli�  gible banks up to $100,000 for each deposit. All members of the Federal  Reserve System are required to insure their deposits with the FDIC, and  almost all commercial banks in the U.S. choose to do so.</p><p>Federal Reserve System U.S. central bank system consisting of 12  Federal Reserve districts with a Reserve bank in the principal commer�  cial city of each district. The system is supervised by a board of gover�  nors in Washington, D.C., as well as by various advisory councils and  committees. As a result of the Federal Reserve Act of 1913, all national  banks are required to join the system; state banks may join if they meet  membership qualifications. The Federal Reserve is responsible for mon�  etary policy. The original act set fixed reserve requirements for the U.S.  fractional reserve banking system. It allowed each district bank to deter�  mine its discount rate, the rate it charged on loans to member banks. The  modern Federal Reserve resulted from the Federal Reserve Act of 1935,  which allowed the board to determine reserve requirements within defined  limits. It became responsible for approving the discount rates of the dis�  trict banks. Most importantly, the act created the Federal Reserve Open  Market Committee, which is responsible for conducting operations in  financial markets that increase or decrease the amount of reserves in the  system. If the Federal Reserve wants to ease monetary policy, it will use  open market operations and increase the amount of reserves through the  purchase of financial assets. Conversely, it can tighten monetary policy  through the sale of financial assets.</p><p>Federal style Neoclassical style of American architecture and interior  design that flourished 1785-1820 (later in governmental buildings) and  was influenced by the Georgian style and the work of James and Robert  Adam. Inspired by the Roman republic, which the new nation believed it  resembled, it was especially associated with Thomas Jefferson and Ben�  jamin H. Latrobe. Characteristics include shallow arches, slender propor�  tions, delicate decoration, and symmetry; entrances are often framed by  columns and pediments, with a fanlight over the door. The University of  Virginia (1817-26) was Jefferson�s greatest Federal-style project.</p><p>federalism Political system that binds a group of states into a larger,  noncentralized, superior state while allowing them to maintain their own  political identities. Certain characteristics and principles are common to  all successful federal systems: a written constitution or basic law stipu�  lating the distribution of powers; diffusion of power among the constitu�  ent elements, which are substantially self-sustaining; and territorial  divisions to ensure neutrality and equality in the representation of vari�  ous groups and interests. Changes require the consent of those affected.  Successful federal systems also have a sense of common nationality and  direct lines of communication between the citizens and all the govern�  ments that serve them. Examples of modern federal systems include the  U.S., Brazil, Germany, and Nigeria.

Most of the essays first appeared serially in New York  newspapers; they were reprinted in other states and then published as a  book in 1788. A few of the essays were issued separately later. All were  signed �Publius.� They presented a masterly exposition of the federal  system and the means of attaining the ideals of justice, general welfare,  and the rights of individuals.</p><p>Federalist Party Early U.S. political party that advocated a strong  central government. Federalist was first used in 1787 to describe support�  ers of the Constitution of the United States, with its emphasis on a federal  union; the Federalist papers was a series of 85 papers (1787-88) published  by Alexander Hamilton, James Madison, and John Jay to persuade New York  voters to ratify the Constitution. By the 1790s other policies defined the  party, including Hamilton�s fiscal program, creation of a central bank, a  tariff system, favourable treatment for U.S. shipping, friendship with Brit�  ain, and neutrality in foreign affairs. The party elected John Adams as  president in 1796 but was unable to organize effectively after 1801. It lost  favour for its opposition to the Embargo Act and the War of 1812; an  internal split by the New England faction (see Hartford Convention) fur�  ther weakened the party. By the 1820s most of its original principles had</p><p>been adopted by the opposition Democratic Party, and the Federalist Party  disappeared. Notable Federalists included John Marshall, Rufus King,  Timothy Pickering, and Charles Pinckney.</p><p>fee In law, an inheritable freehold estate in real property (see real and  personal property). The word derives from fief, as used in feudal law. Mod�  ern property law includes several varieties of fee, including fee simple  (alienable and of indefinite duration), fee tail (granted to an individual  and his or her descendants but subject to reversion if a tenant dies with  no descendants), and life fee or life estate (held only during the lifetime  of the grantee).</p><p>feed Foodstuff grown or developed for livestock and poultry to maintain  the health of the animals and to increase the quality of such end products  as meat, milk, or eggs. Modern feeds are derived from crops grown spe�  cifically for research or from by-products of surplus crops or foods pro�  duced for human consumption. Feeds are categorized as either  concentrates (high in digestibility of nutrients but low in fibre content) or  roughages (high in fibre and comparatively low in digestive nutrients).  Most diets consist of a combination of feeds.</p><p>feedback inhibition Suppression of the activity of an enzyme by a  product of the sequence of reactions in which the enzyme is participat�  ing. When the product accumulates in a cell beyond an optimal amount,  it decreases its own production by inhibiting an enzyme involved in its  synthesis. After the product has been used or broken down, inhibition is  relaxed and formation of the product resumes. Enzymes whose ability to  catalyze a reaction depends on molecules other than the substances on  which they act directly are said to be under allosteric control.</p><p>feeding behaviour Any action of an animal directed toward obtain�  ing nutrients. Each species evolves methods of searching for, obtaining,  and ingesting food for which it can successfully compete. Some species  eat only one type of food, others a variety. Among invertebrates food  choices are instinctual, while among vertebrates they are learned.</p><p>Feiffer, Jules (b. Jan. 26, 1929, New York, N.Y., U.S.) U.S. cartoonist  and dramatist. Feiffer learned his trade while assisting comic-strip artists.  He became famous for Feiffer, a satirical strip whose verbal elements are  usually monologues in which the speaker (sometimes pathetic, sometimes  pompous) exposes his or her own insecurities. His drawings, syndicated  from 1959, are collected in books beginning with Sick, Sick, Sick (1958).  In 1986 he received a Pulitzer Prize. His plays, including Little Murders  (1967; film, 1971), also blend farce and social criticism. His other works  include novels, screenplays (including Carnal Knowledge, 1971), and, in  the 1990s, children�s books.</p><p>Feininger Vfi-niq-orN, Andreas (Bernhard Lyonel) (b. Dec. 27,  1906, Paris, Fr.�d. Feb. 18, 1999, New York, N.Y., U.S.) French-bom  U.S. photographer and writer. Son of painter Lyonel Feininger, he gradu�  ated from the Bauhaus in 1925. After studying architecture, he moved to  Sweden in 1933 and established a firm specializing in architectural and  industrial photography. Among his best-known works are his richly  detailed black-and-white views of New York City, which he achieved  through experimental techniques and devices that he pioneered through�  out his career. He also took many photographs of natural objects, such as  shells, trees, and bones. In 1939 he settled in New York, and from 1943  to 1962 he worked for Life magazine. He also wrote prolifically on pho�  tographic technique.</p><p>Feininger Vfi-niq-oiA, Lyonel (Charles Adrian) (b. July 17, 1871,  New York, N.Y., U.S.�-d.

Around 1910, under the influence of Cubism, he  developed a unique style, using prismatic interpenetrating planes of colour  to depict architectural and marine subjects. He exhibited with Der Blaue  Reiter in Berlin in 1913 and was later an influential teacher at the Bauhaus  (1919-33). His work was a synthesis of art, science, and technology; he  is noted for introducing compositional discipline and lyrical colour to  German Expressionism. After the Nazis came to power, he returned to the  U.S. He was the father of photographer Andreas Feininger.</p><p>feldspar Any of a group of aluminosilicate (containing aluminum and  silicon) minerals that also contains calcium, sodium, or potassium. Feld�  spars are the most common minerals in the Earth�s crust and are the major  component in nearly all igneous rocks found on the Earth, on the Moon,  and in some meteorites.

After col�  laborating with Roberto Rossellini on  the screenplays for Open City (1945)  and Paisan (1946), Fellini undertook  his first solo venture in 1952. It  failed, but his next film, 7 vitelloni  (1953), was a critical success. He  won international acclaim with La  strada (1954, Academy Award), The  Nights of Cabiria (1957, Academy  Award), and La dolce vita (1960). He  continued his distinctive autobio�  graphical style of filmmaking�one  that displayed a sympathetic fascina�  tion with the bizarre�in 8 V 2 (1963,</p><p>Academy Award) but turned to gaudy  spectacle in Juliet of the Spirits  (1965) and Satyricon (1969). The  best of his later films are Amarcord  (1973, Academy Award) and the nostalgic Ginger and Fred (1985). His  wife, Giulietta Masina (1920-94), starred in several of his films.</p><p>felony and misdemeanour In Anglo-American law, two catego�  ries of criminal offense. A crime is classed as one or the other according  to its seriousness. In U.S. law, a felony is typically defined as a crime  punishable by a term of imprisonment of not less than one year. Misde�  meanours are often defined as offenses punishable only by fines or by  short terms of imprisonment in local jails. Crimes in Britain are classi�  fied into indictable offenses (which may be tried by a jury) and summary  offenses (which may be tried by a judge without juries). Codes in Europe  also distinguish offenses of greater dangerousness from lesser crimes.</p><p>felsic rock Igneous rock dominated by the light-coloured, silicon- and  aluminum-rich minerals feldspar and quartz. The presence of these min�  erals gives felsic rock its characteristic light gray colour. The presence of  small amounts of dark minerals rich in magnesium and iron produces  slight colour variations. Typical felsic rocks include granite and rhyolite.</p><p>felting Process that mats together fleece (raw wool) by subjecting it to  moisture, heat, friction, and pressure. Sheep hair have scales that open  somewhat when wet; layering hairs in a parallel fashion and applying  some form of agitation cause the hairs to tighten together in a solid mat.  The result is a lightweight, windproof, and water-resistant fabric that has  been used for millennia to make hats, boots, and tents. Light felting is  sometimes done to woven or knitted wool, a process known as fulling, to  create a thicker and softer fabric.</p><p>female circumcision See cutoridectomy</p><p>feminism Social movement that seeks equal rights for women. Wide�  spread concern for women�s rights dates from the Enlightenment; its first  important expression was Mary Wollstonecraft�s A Vindication of the  Rights of Woman (1792). The 1848 Seneca Falls Convention, convened by  Elizabeth Cady Stanton, Lucretia Mon, and others, called for full legal</p><p>equality with men, including full educational opportunity and equal com�  pensation; thereafter the woman suffrage movement began to gather  momentum. From America the movement spread to Europe. American  women gained the right to vote by constitutional amendment in 1920, but  their participation in the workplace remained limited, and prevailing  notions tended to confine women to the home. Milestones in the rise of  modern feminism included Simone de Beauvoir�s The Second Sex (1949)  and Betty Friedan�s The Feminine Mystique (1963) and the founding in  1966 of the National Organization for Women. See also Equal Rights  Amendment; women's liberation movement.</p><p>feminist philosophy Loosely related set of approaches in various  fields of philosophy that emphasizes the role of gender in the formation  of traditional philosophical problems and concepts and the ways in which  traditional philosophy reflects and perpetuates bias against women. In  social and political philosophy, liberal feminists have advocated making  women�s political and economic opportunities equal to those of men;  socialist or Marxist feminists have argued that women�s oppression is  inherently economic in character; and radical feminists have criticized  liberal political notions such as equality and autonomy as inherently �mas�  culine� (see liberalism). Similar feminist critiques have been made of  notions such as rationality and objectivity in epistemology and metaphysics.  In ethics, feminists have contrasted the traditional masculine approach  based on impersonal and abstract rights and principles with an ethic of  �care� based on personal and concrete relationships and responsibilities.  In the late 20th century feminists influenced by postmodern philosophy  and literary theory pointed out the potential racial, cultural, and class  biases of academic feminists attempting to speak for all women and  argued that no single description of women�s experience or women�s  oppression can be valid for all (see postmodernism).</p><p>Fen River River, Shanxi province, northern China. After rising in the  Guancen Mountains in northwestern Shanxi, it flows southeast to Taiyuan  and then southwest through the central valley of Shanxi to join the Huang  near Hejin. Its total length is about 340 mi (550 km). With a torrential  course and steep gradients, it is a useful waterway only in its lower  reaches. Its valley was an early center of civilization and has remained  an important route, linking the Beijing area with the strategically vital  Shanxi province and the major land routes to Central Asia.</p><p>fencing Sport involving attack and defense with a light sword, specifi�  cally a foil, epee, or sabre. There is evidence of swordplay from ancient  times through the Middle Ages. In the 14th century swordplay became  important in both war and the European gentleman�s daily life, and by the  15 th century guilds of fencing masters had formed. Strokes that were origi�  nally jealously guarded secrets of the individual guilds eventually became  orthodox fencing moves. By the later 17th century various rules and con�  ventions had been imposed. In modern competition�except for sabre  matches�hits are made with the point only; in matches using foils and  sabres, touches to only certain points of the opponents body are counted,  whereas in epee no such restrictions apply. Each valid hit scores one or  more points. Men�s fencing was included in the first modem Olympic  Games in 1896, women�s in the 1924 games. Electrical scoring was intro�  duced in 1936 to eliminate the frequent inaccuracy of human judgment.</p><p>Fenelon \fan-'lo n \, Francois de Salignac de La Mothe- (b. Aug.  6, 1651, Chateau de Fenelon, Perigord, France�d. Jan. 7, 1715, Camb-  rai) French archbishop, theologian, and man of letters. Though generally  conservative, his The Education of Young Gentlewomen (1687), based on  his experience directing a women�s college, supported liberal education  and argued against coercing Protestants to convert. As tutor to a grand�  son of Louis XIV, he composed his best-known work, the novel Les Aven-  tures de Telemaque (1699), but the political ideas it seemed to express  offended Louis, who banished him from the court. He was similarly con�  demned by the church for his leanings toward Quietism, which empha�  sized spiritual passivity. His liberal views on politics and education  exerted a lasting influence on French culture.</p><p>Feng shui Vfoq-'shwaV Traditional Chinese method of arranging the  human and social world in auspicious alignment with the forces of the  cosmos, including qi and yin-yang.

April 19, 1793, Vienna, Austria�d. June 29, 1875, Pra�  gue, Bohemia) Emperor of Austria (1835�48). He was the eldest son of  Emperor Francis II, who sought to protect the principle of succession and  insisted that Ferdinand be the heir, despite Ferdinand�s feeblemindedness  and epilepsy. Ferdinand was crowned king of Hungary in 1830 and  became emperor of Austria in 1835. Government affairs were controlled  by a body of counselors, led by the chancellor, Klemens, prince von Met-  ternich. He was the last Habsburg king of Bohemia (1836), and in 1838  he was crowned king of Lombardy and Venetia. In the revolution of 1848  hostility was directed against his counselors, and Ferdinand abdicated in  favor of his nephew, Francis Joseph.</p><p>Ferdinand (Karl Leopold Maria) (b. Feb. 26, 1861, Vienna,  Austria�d. Sept. 10, 1948, Coburg, Ger.) King of Bulgaria (1908-18).  Elected prince of Bulgaria in 1887, he proclaimed Bulgaria�s indepen�  dence from the Ottoman Empire in 1908 and assumed the title of king or  tsar. He spearheaded the formation of the Balkan League (1912), which led  to the first Balkan War. Bulgaria was defeated in the second Balkan War  (1913), and Ferdinand�s resentments against his former allies determined  Bulgaria�s participation in World War I on the side of the Central Pow�  ers. Following his country�s military defeat in 1918, he was forced to  abdicate in favour of his son, Boris III.</p><p>Ferdinand I (b. March 10, 1503, Alcala de Henares, Spain�d.

In  1526 he took possession of Bohemia  without difficulty, but he faced rival  claimants in Hungary and fought  periodically against the Ottoman  Empire, finally agreeing in 1562 to  pay tribute to the Ottoman sultan for  Austria�s share of Hungary. Ferdi�  nand helped Charles defeat the Prot�  estant Schmalkaldic League, and he  later compromised on the Protestant  issue and signed the Peace of Augs�  burg (1555), ending the era of reli�  gious strife in Germany. Elected  emperor after Charles�s abdication,  which separated the Habsburg  domains into Spanish and Austrian  parts, Ferdinand centralized the imperial administration.</p><p>Ferdinand I (b. Jan. 2/12, 1751, Naples�d. Jan. 4, 1825, Naples) King  of the Two Sicilies (1816-25). He became king of Naples in 1759, as Fer�  dinand IV, when his father ascended the Spanish throne as Charles III. A  weak ruler, he was greatly influenced by his wife, Maria Carolina of Aus�  tria (1752-1814). He engaged Naples in the Austro-English coalition  against the French Revolution in 1793. The French then invaded Naples,  and he fled to Sicily (1798-99, 1806-16).

Jan. 23,  1516) King of Aragon from 1479, king of Castile (as Ferdinand V) from  1474 (joint sovereign with Queen Isabella I until 1504), king of Sicily (as  Ferdinand II, 1468-1516), and king of Naples (as Ferdinand III, 1503�  16). The son of John II of Aragon (1398-1479), Ferdinand married Isa�  bella of Castile in 1469 and fought to impose his authority over the nobles  in the two kingdoms. As part of an effort to modernize Castile, they  banned all religions other than Roman Catholicism, leading to the Span�  ish Inquisition (1478) and the expulsion of the Jews (1492). Conquest of  Granada in 1492 made it possible to support Christopher Columbus�s voy�  ages to the New World. Ferdinand furthered his expansionary policies in  the Mediterranean and in Africa. After the conquest of Naples in 1503,  during the Italian Wars, Spain rivaled France as the most powerful state  in Europe. By uniting the Spanish kingdoms into the nation of Spain, Fer�  dinand began Spain�s entry into the modem period of imperial expansion.</p><p>Ferdinand II (Aragon) See Ferdinand V</p><p>Ferdinand II (b. July 9, 1578, Graz, Styria�d. Feb. 15, 1637, Vienna)  Holy Roman emperor (1619-37), archduke of Austria, king of Bohemia  (1617�19, 1620-27) and king of Hungary (1618-25). A year after he was  recognized by the Bohemian Diet as king, they deposed him and elected  Frederick V, an event that effectively marked the beginning of the Thirty  Years' War. After annihilating the rebel army in 1620, he greatly reduced  the Diet�s power. A rigidly Catholic ruler, he forcibly Catholicized Bohe�  mia and suppressed Protestantism throughout his lands. He maintained  much of his power through the victories of Albrecht W.E. von Wallen�  stein but later concluded a compromise peace with the Protestant princes.  He was the leading champion of the Catholic Counter-Reformation and of  absolutist rule in the Thirty Years� War.</p><p>Ferdinand II (b. Jan. 12, 1810, Palermo, Sicily�d. May 22, 1859,  Caserta) King of the Two Sicilies (1830-59). He followed his father, Fran�  cis I, as king and initially instituted reforms, but his rule gradually became  authoritarian, and he severely repressed a number of liberal and national  revolts. His heavy bombardment of Sicilian cities in 1848 earned him the  name �King Bomba.� His government�s increasingly absolute character  denied the Kingdom of the Two Sicilies a role in the Risorgimento and  caused its collapse and incorporation into Italy in 1860.</p><p>Ferdinand III (b. July 13, 1608, Graz, Inner Austria�d. April 2, 1657,  Vienna) Holy Roman emperor (1637-57), archduke of Austria (1621-57),  king of Hungary (1625-57) and king of Bohemia (1627-57). Denied  command of the Habsburg armies in the Thirty Years' War, Ferdinand con�  spired to overthrow Gen. Albrecht W.E. von Wallenstein, whom he  replaced as commander (1634-35). His leadership of the so-called peace  party at the imperial court led to the Peace of Prague in 1635. As emperor  from 1637, he refused to allow religious freedom in his own domains, but  he compromised with Europe�s Protestant powers and agreed to the Peace  of Westphalia, ending 30 years of religious strife in central Europe.</p><p>Ferdinand VI Spanish Fernando (b. Sept. 23, 1713, Madrid,  Spain�d. Aug. 10, 1759, Villaviciosa de Odon) King of Spain (1746-  59). He was the second son of Philip V and his first wife, Marie-Louise.  The influence of his father�s second wife, Isabella Farnese, kept Ferdinand  out of politics during his father�s reign. During his own reign he tried to  avoid conflicts while relying on his father�s minister to bring about  reforms. Ferdinand, the second Bourbon Spanish king, and his wife, Maria  Barbara, were patrons of the arts and learning. On his death, the crown  passed to his half brother, Charles III.</p><p>Ferdinand VII Spanish Fernando (b. Oct. 14, 1784, El Escorial,  Spain�d. Sept. 29, 1833, Madrid) King of Spain (1808, 1813-33). He  became king briefly in 1808 after the French invasion of Spain forced the  abdication of his father, Charles IV. Napoleon soon replaced him as king  with Joseph Bonaparte and held Ferdinand in France (1808-13). The Span�  ish populace rose against the French invaders in the name of Ferdinand,  who became known as �the Desired.� In 1812 independent Spaniards  adopted a liberal constitution, which Ferdinand overthrew on his return  as king in 1813 to rule in an absolutist style. His reign saw the loss of  most of Spain�s possessions in the Americas. He abolished the Salic Law</p><p>of Succession to allow his daughter (the future Isabella II) instead of his  brother (Don Carlos [1788-1855]) to succeed him, which triggered the  opposition movement, Carusm.</p><p>Ferdinand the Catholic See Ferdinand V</p><p>FerdowsI \for-'dau-se\ or Firdusi or FirdousI rfor-'dii-seV orig.

He gave the final and enduring form to the Persian national epic,  the Shah-nameh (completed c. 1010; �Book of Kings�), a poem based  mainly on an earlier prose history. His language is still readily intelligible  to modern Iranians, who regard the poem�s nearly 60,000 couplets as a  sonorous, majestic evocation of a glorious past.

Hungarian psychoanalyst. After  receiving his M.D. from the University of Vienna and serving as an army  doctor, he met Sigmund Freud in 1908 and became a member of Freud�s  inner circle, the Vienna Psychoanalytic Society. He founded the Hungar�  ian Psychoanalytic Society in 1913 and began teaching psychoanalysis at  the University of Budapest in 1919. He experimented with techniques of  therapy and diverged from classic psychoanalytic practice in some  respects (e.g., arguing that recovery of traumatic memories was not essen�  tial for modifying neurotic behaviour and emphasizing the need for thera�  pists to create a loving, permissive atmosphere). His works include The  Development of Psychoanalysis (with Otto Rank; 1924).</p><p>Fergana Valley or Fergana Basin \,fir-g9-'na\ Large valley, west�  ern Central Asia. It is mainly in eastern Uzbekistan and partly in Tajiki�  stan and Kyrgyzstan and is situated between the Tien Shan system and  the smaller Gissar and Alay ranges. It has an area of 8,500 sq mi (22,000  sq km). One of the most densely populated areas of Central Asia, it is a  major producer of cotton, fruit, and raw silk. Among the mineral depos�  its exploited are coal, petroleum, and mercury. It was conquered by the  Arabs (8th century ad), Genghis Khan (13th century), and Timur (14th cen�  tury).

Aug. 17, 1601, Beaumont-de-  Lomagne, France�d. Jan. 12, 1665,</p><p>Castres) French mathematician. Of  Basque origin, Fermat studied law at  Toulouse and developed interests in  foreign languages, Classical litera�  ture, ancient science, and mathemat�  ics. A jurist by profession, he  produced major mathematical break�  throughs independently and collabo-  ratively. A contemporary of Rene  Descartes, he discovered indepen�  dently the basic principles of analytic  geometry, but, because Fermat�s  work was published posthumously,  the field became known as Cartesian  geometry. He found equations for  tangent lines to curves through pro�  cesses equivalent to differentiation  and was coauthor (with Blaise Pascal)  of PROBABILITY THEORY. His work in NUM�  BER theory, especially divisibility, led  to some of its most important theorems. He seldom demonstrated his  results, which led to a centuries-long quest to prove a famous conjecture  that Fermat claimed was easily shown (see Fermat's last theorem).</p><p>Fermat's last theorem Statement that there are no natural numbers  x, y, and z such that jc" + y n = z", in which n is a natural number greater  than 2. About this, Pierre de Fermat wrote in 1637 in his copy of Diophan-  tus�s Arithmetical �I have discovered a truly remarkable proof but this  margin is too small to contain it.� Although the theorem was subsequently  shown to be true for many specific values of n, leading to important  mathematical advances in the process, the difficulty of the problem soon  convinced mathematicians that Fermat never had a valid proof. In 1995  the British mathematician Andrew Wiles (b. 1953) and his former student  Richard Taylor (b. 1962) published a complete proof, finally solving one  of the most famous of all mathematical problems.</p><p>fermentation Process that allows respiration to occur in the absence  of oxygen. Biologically, it allows cells to obtain energy from molecules  (e.g., glucose) anaerobically. Glycolysis, the breakdown of glucose, is a  form of fermentation.

As a professor at the Univer�  sity of Rome, he began the work, later fully developed by P.A.M. Dirac,  that led to Fermi-Dirac statistics. He developed a theory of beta decay that  applies to other reactions through the weak force, which was not improved  until 1957, when the weak force was found not to conserve parity. He dis�  covered neutron-induced radioactivity, for which he was awarded a 1938  Nobel Prize. After receiving the award in Sweden, he never returned to  fascist Italy but instead moved directly to the U.S., where he joined the  faculty of Columbia University and soon became one of the chief archi�  tects of practical nuclear physics. A member of the Manhattan Project, he  was an important figure in the development of the atomic bomb; in 1942  he directed the first controlled nuclear chain reaction. He received the  Congressional Medal of Merit in 1946. In 1954 he became the first recipi�  ent of the U.S. government�s Enrico Fermi Award. Element number 100,  fermium, was named in his honour.</p><p>Fermi-Dirac statistics In quantum mechanics, one of two possible  ways (the other being Bose-Einstein statistics) in which a system of indis�  tinguishable particles can be distributed among a set of energy states. Each  available discrete state can be occupied by only one particle. This exclu�  siveness accounts for the structure of atoms, in which electrons remain in  separate states rather than collapsing into a common state. It also accounts  for some aspects of electrical conductivity. This theory of statistical  behaviour was developed first by Enrico Fermi and then by P.A.M. Dirac  (1926-27). The statistics apply only to particles such as electrons that have  half-integer values of spin; the particles are called fermions.</p><p>fermion Any of a group of subatomic particles having odd half-integral  spin (Vi, %).

It became a cultural centre and  the seat of a principality, but it declined after its incorporation into the  Papal States in 1598. The site of an Austrian garrison from 1832, Ferrara  became part of the Kingdom of Italy in 1861. It was severely damaged  in World War II.

Fear of facing the  Turks without Western support led the Eastern participants to sign the  Decree of Union (1439), but on their return to Constantinople most  renounced it. Union was officially declared in Hagia Sophia in 1452, but  the following year the Ottoman Empire captured Constantinople, and the  few partisans of the union fled. In 1448 a council of Eastern bishops con�  demned it officially.

The  common ferret (Mustela putorius furo) is a domesticated form of the  European polecat. It has a long, lithe body and is brown, black, or white  (albino). Its average length is 20 in. (51 cm), including the 5-in. (13-cm)  tail, and it weighs about 2 lbs (1 kg). It was originally domesticated for  hunting mice, rats, and rabbits; today ferrets are commonly kept as pets.  The black-footed ferret (M. nigripes), of the North American plains, has  a black mask across the eyes and brownish black markings on the feet  and tail tip. It is an endangered species, owing to the loss of its main  source of food, the prairie dog.</p><p>ferrimagnetism Type of permanent magnetism that occurs in solids, in  which the magnetic fields associated with individual atoms spontaneously  align themselves, some parallel (as in ferromagnetism), and others anti�  parallel, or paired off in opposite directions (as in antiferromagnetism).  The materials are less magnetic than ferromagnets, as the antiparallel  atoms dilute the magnetic effect of the parallel arrangement. Ferrimag�  netism occurs mainly in magnetic oxides known as ferrites. Above a tem�  perature called the Curie point, the spontaneous alignment is disrupted  and ferrimagnetism is destroyed, but it is restored upon cooling below the  Curie point.</p><p>ferroalloy Alloy of iron (less than 50%) and one or more other metals,  important as a source of various metallic elements in the production of  alloy steels. The principal ferroalloys are ferromanganese, ferrochromium,  ferromolybdenum, ferrotitanium, ferrovanadium, ferrosilicon, ferroboron,  and ferrophosphorus. They usually have lower melting ranges than do the  pure elements and can be incorporated more readily in the molten steel.  Ferroalloys are prepared from charges of the nonferrous metal ore, iron  or iron ore, coke or coal, and flux by treatment at high temperature in  submerged-arc electric furnaces.</p><p>ferromagnetism Physical phenomenon in which certain electrically  uncharged materials strongly attract others. It is associated with iron,  cobalt, nickel, and some alloys or compounds containing these elements.  It is caused by the alignment patterns of the material�s atoms, each of  which acts as a simple electromagnet, due to the motion and spin of the</p><p>electrons. The tiny magnets spontaneously align themselves in the same  direction, so their magnetic fields reinforce each other. Ferromagnetic mate�  rials are magnetized easily. Above a temperature called the Curie point,  they cease to be magnetic, but they become ferromagnetic again upon  cooling below the Curie point.

His government established  free, compulsory, secular education (1882), enacting such anticlerical  measures as dissolving the Jesuits and forbidding their members to teach.

The term describes a crescent�  shaped area of arable land, probably more agriculturally productive in  antiquity than it is today. Historically the area stretched from the south�  eastern coast of the Mediterranean Sea around the Syrian Desert north of  the Arabian Peninsula to the Persian Gulf; in general, it often includes the  Nile River valley as well. Sedentary agricultural settlements in the Fertile  Crescent can be dated to c. 8000 bc.

About 80% of healthy, fertile women are able to conceive  within one year if they have intercourse regularly without contraception.  Normal fertility requires the production of enough healthy sperm by the  male and viable eggs by the female, successful passage of the sperm  through open ducts from the male testes to the female fallopian tubes,  penetration of a healthy egg, and implantation of the fertilized egg in the  lining of the uterus (see reproductive system). A problem with any of these  steps can cause infertility.</p><p>fertilization Reproductive process in which a male sex cell (sperm)  unites with a female sex cell (egg). During the process, the chromosomes  of the egg and sperm will merge to form a zygote, which will divide to  form an embryo. In humans, sperm travel from the vagina through the  uterus to a fallopian tube, where they surround an egg released from an  ovary usually two or three days earlier. Once one sperm has fused with  the egg cell membrane, the outer layer becomes impenetrable to other  sperm. See also cross-fertilization, self-fertilization.

Originally a Whig, he opposed the exten�  sion of slavery to the territories, and he was one of the leaders of the  movement that resulted in the formation of the Republican Party (1854).  Despite his personal dislike for Pres. Andrew Johnson, he voted for acquit�  tal in Johnson�s Senate impeachment trial.</p><p>fetal alcohol syndrome (FAS) Various congenital disorders in a  newborn caused by the mother drinking alcohol during pregnancy. The  main symptoms are retarded growth, abnormalities of the central nervous  system, and certain face and head abnormalities. The child may be men�  tally retarded. Behavioral problems (e.g., poor concentration, impulsive�  ness) are sometimes the only obvious symptoms. The syndrome is  common in babies born to chronic alcoholics, but health care organiza�  tions now commonly recommend that women cease drinking alcohol  entirely while pregnant. Other disorders have been linked to alcohol in  breast milk.</p><p>fetial Vfe-shol\ Any of a group of 20 Roman priestly officials who dealt  with foreign relations. Selected from noble families and appointed for life,  they acted as emissaries to foreign lands in times of conflict. When Rome  was offended by another city-state, the fetials would visit the city-state  and demand satisfaction. They also delivered treaties and made formal</p><p>declarations of war, based on the decisions of the Senate. This priesthood  had faded by the late republic, but was later revived by Augustus.</p><p>fetish Object believed to have magical power to protect or aid its owner,  and by extension, an object regarded with superstitious or extravagant  trust or reverence. In the 18th century it was applied to West African  amulets; it has also been used for various items in American Indian reli�  gion. In psychology, a fetish is an object that substitutes for a person as  the focus of sexual desire. See also fetishism.</p><p>fetishism In psychology, erotic attachment to an inanimate object or a  nongenital body part whose real or fantasized presence is necessary for  sexual gratification. The object is most commonly some other body part  or an article of clothing. From the time of its identification by Sigmund  Freud in 1927, fetishism was thought to occur almost exclusively among  men, but in the late 20th century that notion was challenged by several  new studies. See also fetish.</p><p>fetus \'fet-os\ Unborn young of any vertebrate, particularly mammals,  after it has acquired its basic form. In humans, this stage begins about  eight weeks after conception (see embryo). The fetal stage, marked by  increased growth and full development of the organ systems, climaxes in  birth (see pregnancy, parturition). By the end of the third month, the arms  and legs of the human fetus begin to move and reflexive movements (such  as sucking) begin. Four months after conception, the fetus is about 5.3 in.  (135 mm) long and weighs about 6 oz (170 g). During the fifth month,  downy hairs (lanugo) cover the body and the skin becomes less transpar�  ent. At seven months, a protective greasy substance (vemix caseosa) cov�  ers the reddish, wrinkled skin. Fat is deposited under the skin during the  eighth month, when the fetus typically weighs about 5 lbs (2.2 kg). A  full-term fetus is about 266 days old.</p><p>feudal land tenure System by which land was held by tenants from  lords. In England and France, the king was lord paramount and master of  the realm. He granted land to his lords, who granted land to their vassals  and so on down to the occupying tenant. Tenures were divided into free  and unfree. Free tenure included tenure in chivalry, as in the case of knight  service, and socage (tenure by agricultural service fixed in amount and  kind). The main type of unfree tenancy was villenage, a limited form of  servitude. See also feudalism, fief, landlord and tenant, manorialism.</p></section><section><p>feudalism Term that emerged in the 17th century that has been used  to describe economic, legal, political, social, and economic relationships  in the European Middle Ages. Derived from the Latin word feudum (fief)  but unknown to people of the Middle Ages, the term �feudalism� has been  used most broadly to refer to medieval society as a whole, and in this way  may be understood as a socio-economic system that is often called mano�  rialism. It has been used most narrowly to describe relations between lords  and vassals that involve the exchange of land for military service. Feu�  dalism in this sense is thought to have emerged in a time of political dis�  order in the 11th century as a means to restore order, and it was later a  key element in the establishment of strong monarchies. �Feudalism� also  has been applied, often inappropriately, to non-Western societies where  institutions similar to those of medieval Europe are thought to have  existed. The many ways �feudalism� has been used have drained it of  specific meaning, however, and caused some scholars to reject it as a use�  ful concept for understanding medieval society.</p><p>Feuerbach Vfoi-or-.bakV Ludwig (Andreas) (b. July 28, 1804,  Landshut, Bavaria�d. Sept. 13, 1872, Rechenberg, Ger.) German phi�  losopher. The son of an eminent jurist, he studied under G.W.F. Hegel in  Berlin but later abandoned Hegelian idealism for a naturalistic material�  ism. In Thoughts on Death and Immortality (1830), he attacked the con�  cept of personal immortality. His Abelard and Heloise (1834) and Pierre  Bayle (1838) were followed by On Philosophy and Christianity (1839),  in which he claimed that �Christianity has in fact long vanished not only  from the reason but from the life of mankind.� In The Essence of Chris�  tianity (1841), he proposed that God is merely the outward projection of  mankind�s inward nature. Some of his views were later endorsed by Karl  Marx and Friedrich Engels.</p><p>Feuillants \fce-'ya n \ Club Conservative French political club in the  French Revolution, which met in the former monastery of the Feuillants  (Reformed Cistercians) in Paris.

It most often occurs with infection. Normal  core body temperature, measured orally, does not exceed 99�F (37.2�C).  Up to 105�F (40.6�C), fever causes weakness and is best treated with aspi�  rin, acetaminophen, or other antipyretic drugs. At 108�F (42.2�C) or more,  it can lead to convulsions and death. In treatment, it is important to know  the underlying cause. Fever appears to be a defense against infectious dis�  ease, stimulating leukocytes and increasing antibody production and per�  haps killing or inhibiting bacteria and viruses that live within a narrow  temperature range.</p><p>Feydeau \fa-'do\, Georges (-Leon-Jules-Marie) (b. Dec. 8,1862,  Paris, France�d. June 5, 1921, Paris) French playwright. Also an actor  and director, he wrote 39 plays between 1881 and 1916, taking the farce  to new heights on the French stage. His plots often depended on far�  fetched cases of mistaken identity, and he used complicated mechanical  props and elaborate stage settings. His plays included The Girl from Max�  im�s (1899), A Flea in Her Ear (1907), and Keep an Eye on Amelie!  (1908). His farces have remained in the repertoire of the Comedie-  Francaise.</p><p>Feynman Vfin-monV Richard P(hillips) (b. May 11, 1918, New  York, N.Y., U.S.�d. Feb. 15, 1988, Los Angeles, Calif.) U.S. theoretical  physicist. He received his Ph.D. from Princeton University. During World  War II he worked on the Manhattan Project. From 1950 he taught at the  California Institute of Technology. The Feynman diagram was one of the  many problem-solving tools he invented. With Julian Schwinger (b. 1918)  and Shinichiro Tomonaga (1906-79), he shared a 1965 Nobel Prize for  his brilliant work on quantum electrodynamics. He was principally respon�  sible for identifying the cause of the 1986 Challenger disaster. Famed for  his wit, he also wrote best-selling books on science. His work, which tied  together all the varied phenomena at work in light, radio, electricity, and  magnetism, altered the way scientists understand the nature of waves and  particles.</p><p>Feynman diagram Graphical method of representing the interactions  of elementary particles. It was invented by Richard P. Feynman, who intro�  duced the diagrams as an aid to calculating the processes that occur  between electrons and photons. A Feynman diagram consists of two axes,  one representing space, the other representing time. Electrons are repre�  sented as straight lines, while photons are shown as wavy lines. The inter�  action between particles appears as a junction of three lines, or a vertex.  Feynman diagrams are now used to show all types of particle interac�  tions.</p><p>Fez See Fes</p><p>Fezzan \fe-'zan\ Arab/c Fazzan \fa-'zan\ ancient Phazania Historic  region, southwestern Libya. A part of the Sahara, most of its inhabitants  dwell in oases in the interior. Southern Fezzan is noted for its date palms,  which cover several hundred thousand acres scattered in numerous oases.  It was conquered by the Romans in the 1st century bc and by the Arabs  in the 7th century ad. The Ottomans made it part of their empire in 1842.  Fezzan was made part of Tripoli by the Italians in 1912, and it became a  province of the United Kingdom of Libya (1951-63). Thereafter it was  part of Libya.</p><p>Fianna Fail Vfe-o-ns-'foiL Irish "Soldiers of Destiny" Political  party in Ireland, also called, loosely, the Republican Party. It was formally  constituted in 1926 by those opposed to the treaty with Britain that in  1921 brought about the Irish Free State. They were organized and led by  Eamon de Valera. Fianna Fail remained the principal governing party from  1932 until 1973, but from 1961 it did so with the aid of other parties. It  returned to power in coalition governments in the 1980s and �90s. Its main  opposition was from Fine Gael.</p><p>Fiat SpA International holding company and major Italian manufacturer  of automobiles, trucks, and industrial vehicles and components. In 1899  Giovanni Agnelli (1866-1945) founded the firm that was incorporated as  Fiat in 1906; he led the firm until his death. His grandson Giovanni Agnelli  (1921-2003) served as chairman from 1966 until 1996, when his title  became honorary. Paulo Fresco was named chairman in 1998. In 1979 the  corporation converted to a holding company; in 1986 it acquired the  sports-car manufacturer Alfa Romeo SpA.

He  found that rats that had suffered stomach-tissue inflammation caused by  the larvae of a worm infecting cockroaches the rats had eaten subsequently  developed stomach tumours, and he induced tumours in mice and rats by  feeding them infected cockroaches. His work, for which he received a  1926 Nobel Prize, supported the prevailing concept that cancer is caused  by tissue irritation and led to production of chemical carcinogens for use  in cancer research.</p><p>Fibonacci sequence \,fi-b3-'na-che\ In mathematics, a sequence of  numbers with surprisingly useful applications in botany and other natu�  ral sciences. Beginning with two l�s, each new term is generated as the  sum of the previous two: 1, 1, 2, 3, 5, 8, 13, ... . The 13th-century math�  ematician Leonardo of Pisa (c. 1170-after 1240), also known as  Fibonacci, discovered the sequence but did not explore its uses, which  have turned out to be wide and various. For example, the number of pet�  als in most types of flowers and numbers involved in branching and seed-  formation patterns come from the Fibonacci sequence. The ratio of any  two successive terms approaches the value of the golden ratio as the terms  become large.</p><p>fibre, dietary Food material not digestible by the human small intes�  tine and only partially digestible by the large intestine. Fibre is beneficial  in the diet because it relieves and prevents constipation, appears to reduce  the risk of colon cancer, and reduces plasma cholesterol levels and there�  fore the risk of heart disease. Fibre also slows gastric emptying and con�  tributes to satiety. Whole grains, vegetables, nuts, and fruits are all good  sources. See also nutrition.</p><p>fibre optics Thin transparent fibres of glass or plastic that transmit light  through their length by internal reflections, used for transmitting data,  voice, and images. Fibre-optic technology has virtually replaced copper  wire in long-distance telephone lines and is used to link computers in local  area networks, with digitized light pulses replacing the electric current  formerly used for the signal. Telecommunication using fibre optics is usu�  ally conducted with infrared light. Fibre optics uses light in the visible  wavelengths to transmit images directly, in various technical devices such  as those developed for endoscopy.</p><p>fibreglass or glass fibre Fibrous form of glass, developed in the  1930s. Liquid glass issues in fine streams through hundreds of fine  nozzles, and the solidifying streams are gathered into a single strand and  wound onto a spool. Strands can be twisted into yams, woven into fab�  rics, or chopped into short pieces and then bonded into mats. Glass fila�  ments and yams add strength and electrical resistivity to molded plastic  products. Glass fabrics are used as electrical insulators and as reinforc�  ing belts in automobile tires. Discontinuous fibres are formed into wools,  mats, or boards, commonly used in buildings, appliances, and plumbing.</p><p>fibrillation See atrial fibrillation, ventricular fibrillation  fibrolite See sillimanite</p><p>fibromyalgia Chronic syndrome that is characterized by musculoskel�  etal pain, often at multiple sites.

To demonstrate that practical reason is really the root of reason in its  entirety, the absolute ground of all knowledge as well as of humanity  altogether, he started from a supreme principle, the ego, which is inde�  pendent and sovereign, so that all other knowledge is deducible from it.  In his famous patriotic lectures Addresses to the German Nation (1807-  OS) he attempted to rally German nationalists against Napoleon. He is  regarded as one of the great transcendental idealists.

Oct. 1, 1499, Careggi, near Florence) Italian philosopher,  theologian, and linguist. His translations and commentaries on the writ�  ings of Plato and other Classical Greek authors marked the beginning of  the Florentine Platonist Renaissance. In conceiving the universe as a hier�  archy of substances that descends from God to matter, he was strongly  influenced by Neoplatonism and medieval views. The Cambridge Platonists  and related movements in France and Italy reflect Ficino�s interpretation  of Platonism. Of his original writings, Platonic Theology (1482) and Book  on the Christian Religion (1474) are most significant.</p><p>fiddler crab Any of about 65 species of decapods (genus Uca) whose  males hold one claw, always much larger than the other, somewhat like a  violin. Both claws of the female are relatively small. Fiddler crabs often  live in large numbers on beaches in temperate to tropical regions of the  world. They inhabit water-covered burrows up to about 1 ft (30 cm) deep  and feed on algae and other organic matter. Common North American  species (e.g., marsh fiddler, china-back fiddler) live all along the U.S.  Atlantic coast. Brightly coloured, they range in body size from about 1  to 1.2 in.

In the 1920s he began conducting and recording with  his own Boston Sinfonietta and various choral groups. In 1929 he orga�  nized a series of open-air concerts, which was successful enough to even�  tually become an institution, the Boston Pops. Thereafter his name was  inextricably linked with the Pops, which achieved enormous success  under his direction.</p><p>fief Vfef\ In European feudalism, a vassal�s source of income, granted to  him by his lord in exchange for his services. The fief usually consisted  of land and the labor of peasants who were bound to cultivate it. The  income it provided supported the vassal, who fought for his lord as a  knight. Dignities, offices, and money rents were also given in fief.</p><p>Field In physics, a region in which each point is affected by a force.  Objects fall to the ground because they are affected by the force of earth�s  gravitational field (see gravitation). A paper clip, placed in the magnetic  field surrounding a magnet, is pulled toward the magnet, and two like  magnetic poles repel each other when one is placed in the other�s mag�  netic field. An electric field surrounds an electric charge; when another  charged particle is placed in that region, it experiences an electric force  that either attracts or repels it. The strength of a field, or the forces in a  particular region, can be represented by field lines; the closer the lines,  the stronger the forces in that part of the field.

Born on a farm,  he became an errand boy for a dry-goods store at age 16. He moved to  Chicago and was hired in 1856 by a mercantile house, in which he later  attained full partnership. In 1867 he and a partner bought the merchan�</p><p>dising firm they had joined two years earlier, and in 1888 he bought out  his partner, creating Marshall Field and Co. In his store Field emphasized  customer service, liberal credit, the one-price system, and the acceptance  of returned merchandise.

In 1849 he  moved to California, where he later joined the state supreme court. In  1863 he was appointed by Pres. Abraham Lincoln to the Supreme Court  of the United States; he served until 1897. He became chief architect of  the constitutional approach that largely exempted U.S. industry from gov�  ernment regulation after the American Civil War, basing his interpretation  principally on the U.S. Constitution�s 14th Amendment (1868), which had  been passed as a civil-rights measure. Field�s stance toward industry  would be maintained by the Court until the 1930s.</p><p>field hockey or hockey Game played with curve-ended sticks  between two teams of 11 players. It is played on a field 100 yd (91.4 m)  by 60 yd (55 m) in size. The object is to use the sticks to direct a ball  into the opponent�s goal. Field hockey originated in English schools in  the late 19th century, and the British Army introduced it into India and  the Far East. By 1928 it had become India�s national game. Men�s field  hockey has been included in the Olympic Games since 1908, women�s  since 1980. The game was introduced into the U.S. in 1901 and became  particularly popular at women�s schools, colleges, and clubs.

Field mice in this  genus are found in fields, woodlands, and mountain meadows in the warm  and temperate parts of Eurasia. They are grayish or light or reddish brown  and are 2-5 in. (6-12 cm) long excluding the tail. They generally live in  burrows and build nests of grass and other plants. They eat seeds, roots,  and other plant material, occasionally damaging crops or young trees.</p><p>Field of Cloth of Gold Setting for meetings between Henry VIII of  England and Francis I of France in June 1520, near Calais, France. Splen�  did temporary palaces were erected for each king, and jousts and other  entertainments were held.

In July Henry  met Emperor Charles V, Francis�s rival, near Calais, and they agreed to  make no new alliances with France for two years.</p><p>field theory In mathematics, the study of the structure of a set of  objects (e.g., numbers) with two combining operations (e.g., addition and  multiplication). Such a system, known as a field, must satisfy certain  properties: associative law, commutative law, distributive law, an additive  identity (�zero�), a muliplicative identity (�one�), additive inverses (see  inverse function), and multiplicative inverses for nonzero elements. The  sets of rational numbers, real numbers, and complex numbers are fields under  ordinary addition and multiplication. The investigation of polynomial  equations and their solutions led to the development of field theory.</p><p>field trial Competitive trial of sporting dogs under conditions that  approximate or simulate those found in the hunting field.

In 1748 he was appointed a magistrate, in which role he established  a new tradition of justice and suppression of crime in London. He prob�  ably wrote Shamela (1741), a burlesque of Samuel Richardson�s Pamela  that he never claimed. In the entertaining and original Joseph Andrews  (1742) he also parodies Richardson�s novel. Tom Jones (1749), his most  popular work, is noted for its great comic gusto, vast gallery of charac�  ters, and contrasted scenes of high- and lowlife. The more sober Amelia  (1751) anticipates the Victorian domestic novel. In these works he helped  develop the English novel as a planned, realistic narrative genre survey�  ing contemporary society.</p><p>fieldlark See pipit</p><p>Fields, Dame Grade orig.

He was a vaudeville headliner as a juggler and appeared  for seven seasons (1915-21) in the Ziegfeld Follies. His starring role in  the stage hit Poppy (1923) brought him to Hollywood for its film adap�  tation, Sally of the Sawdust (1925). He emerged as a top film comedian  only after the advent of sound pictures, when audiences could hear his  distinctive raspy voice. His screen personality�an unlovable but hilari�  ous con man, braggart, misanthrope, and hater of children and dogs�was  largely his own.

Yielding the well-known figs of commerce, F.  carica is native to an area from Asiatic Turkey to northern India, but  natural seedlings grow in most Mediterranean countries, where figs are  used extensively, both fresh and dried. It is a bush or small tree with broad,  rough, deciduous leaves (see deciduous tree). Hundreds of different vari�</p><p>eties are grown in various parts of the world. The fig was one of the first  fruit trees to come under cultivation. Its fruit contains significant amounts  of calcium, potassium, phosphorus, and iron.</p><p>Figaro, Le Morning daily newspaper published in Paris, once one of the  great newspapers of France and of the world. Founded in 1826 as a witty  gossip sheet on the arts, by 1866 it was a well-written daily filled with  political discourse. Though the paper�s reputation faltered at times and it  suspended publication during World War II, in the postwar years it became  the voice of the French upper middle class, providing broad subject cov�  erage while maintaining an independent editorial stance. In the 1960s and  �70s the staff was rent by conflicts over its leadership. In 1975 the paper was  bought by the conservative Robert Hersant, who ran it until his death in  1996. U.S. investment firm Carlyle Group owned a minority share in Le  Figaro Group from 1999 to 2002, when full ownership passed to Socpresse.</p><p>fighter aircraft Aircraft designed primarily to secure control of essen�  tial airspace by destroying enemy aircraft in combat. Designed for high  speed and maneuverability, they are armed with weapons capable of strik�  ing other aircraft in flight. Developed early in World War I, they engaged  in aerial combat with other fighters, shot down enemy bombers, and con�  ducted various tactical missions. Most were biplanes with wooden frames  and cloth skins, equipped with light machine guns synchronized to fire  through the propeller. World War II saw the development of all-metal  monoplanes that exceeded speeds of 450 mph (725 kph). Famous fight�  ers of the period included the Focke-Wulf 190, the P-47 and P-51, and  the Zero. Jet aircraft were produced at the end of the war, and jet fighters  such as the U.S. Sabre and the Soviet MiG saw extensive service in the  Korean War and later conflicts.

June 8, 1990, San Jose) Costa Rican statesman and presi�  dent (1948-49, 1953�58, 1970-74). Educated in Costa Rica, Mexico, and  the U.S., he became an opponent of the right-wing regime of Rafael Angel  Calderon, and in 1948 he led an uprising to force Calderon to yield the  presidency to the democratically elected Otilio Ulate. A junta dominated  by Figueres wrote a new constitution that abolished the army and gave  women the right to vote, and the presidency was turned over to Ulate in  1949. Figueres himself was elected president by a landslide in 1953; gov�  erning as a moderate socialist, he adopted a pro-U.S. policy and quickly  outlawed the Communist Party. Returned to power in 1970, he became a  symbol of the democratic left and is given much credit for Costa Rica�s  enduring stability and democracy.</p><p>figure of speech Form of expres�  sion used to convey meaning or  heighten effect, often by comparing  or identifying one thing with another  that has a meaning or connotation  familiar to the reader or listener. An  integral part of language, figures of  speech are found in oral literatures as  well as in polished poetry and prose  and in everyday speech. Common  figures of speech include simile, meta�  phor, personification, hyperbole,  irony, alliteration, onomatopoeia, and  puns.</p><p>figure skating Sport in which ice  skaters, singly or in pairs, perform  various jumps, spins, and footwork.  The figure skate blade has a special  serrated toe pick, or toe rake, at the  front. Figure-skating events, held in  the 1908 and 1920 Olympic Games,  have constituted part of the Winter  Olympics since they were inaugu�  rated in 1924. Until 1991, competi�  tion included a compulsory section in  which prescribed figures were traced.

Jumps fall into two main groups: the edge  jumps (such as the axel, the salchow, and the loop), which take off from one  foot; and the toe jumps (such as the toe loop, the flip, and the lutz), which  are edge jumps assisted by a vault off the toe pick of the other foot. Addi�  tional pair moves, involving a man and a woman skating together, include  lifts and throw jumps. Figure-skating programs are judged on both techni�  cal merit and artistic impression. See also ice dancing.</p><p>figurehead Ornamental symbol or figure placed on a prominent part</p><p>of a ship, usually at the bow. It could  be a religious symbol, a national  emblem, or a figure symbolizing the  ship�s name. The custom of decorat�  ing a ship probably began in ancient  Egypt or India and was followed by  the Chinese, Phoenicians, Greeks,  and Romans. As early as 1000 bc, the  stem- and sternposts were carved  and painted to distinguish one ship  from another. The Vikings built ships  with high bows and a projecting stem  bearing a menacing figurehead, simi�  lar to the ships of William I the Con�  queror as seen in the Bayeux Tapestry.  Figureheads have historically varied  in size from 18 in. (45 cm) to 8-9 ft  (2.5 m). They remained popular until  after World War I.</p><p>figwort Any of about 200 species  of coarse plants that make up the  genus Scrophularia (family Scro-  phulariaceae), native to open wood�  lands in the Northern Hemisphere,  smelling plants with purple, greenish,  spikes.</p><p>Figurehead from the Oseberg ship,  Viking, about ad 800; in the Museum  of National Antiquities, Oslo</p><p>� UNIVERSITETETS OLDSAKSAMLING, OSLO, NORWAY;  PHOTOGRAPHER, EIRIK IRGENS JOHNSEN</p><p>Figworts are tall, frequently foul-  or yellow flowers in large branched</p><p>Fiji officially Republic of Fiji Country and archipelago, South Pacific  Ocean. It lies east of Vanuatu and southwest of Samoa. Area: 7,055 sq mi  (18,272 sq km). Population (2005 est.): 846,000. Capital: Suva. The  majority of Fijians are of mixed Melanesian-Polynesian ancestry, with a  large South Asian minority. Languages: English (official), Fijian. Reli�  gions: Christianity (mostly Protestant, also other Christians, Roman  Catholic), Hinduism, Islam. Currency: Fiji dollar. Fiji lies 1,300 mi (2,100  km) north of New Zealand and comprises some 540 islets and 300 islands,  of which about 100 are inhabited. The main islands are Viti Levu and  Vanua Levu. Fiji also includes, since 1881, Rotuma, an island located  about 400 mi (640 km) to the northwest. The two large islands are moun�  tainous and volcanic in origin, rising abruptly from densely populated  coasts to forested central mountains. The smaller islands are also volca�  nic, and all are ringed by rocky shoals and coral reefs. The coastal deltas  of the principal rivers contain most of the fertile arable land. The climate  is tropical oceanic. Fiji has a market economy based largely on agricul�  ture (particularly sugar production), tourism, and light industries; gold and  silver are mined. Fiji is a republic with two legislative houses; its chief  of state is the president, while the head of government is the prime min�  ister. Archaeological evidence shows that the islands were occupied in the  late 2nd millennium bc. The first European sighting was by the Dutch in  the 16th century; in 1774 the islands were sighted by Capt. James Cook,  and in 1792 Capt. William Bligh explored them. Traders and the first mis�  sionaries arrived in 1835, and European settlers began arriving in the  1860s. In 1874 Fiji was proclaimed a crown colony. It became indepen�  dent as a member of the Commonwealth in 1970 and was declared a  republic in 1987 following a military coup. Elections in 1992 restored  civilian rule. A new constitution was approved in 1997.</p><p>Filarete V.fe-la-'re-taX orig. Antonio di Pietro Averlino (b. c. 1400,  Florence?�d. c. 1469, Rome) Italian architect and sculptor. In 1451 he  entered the service of the duke of Milan. He designed the Ospedale Mag-  giore in Milan (1457-65), which is among the first Renaissance buildings  in Lombardy. He is chiefly important for his Trattato d�architettura  (�Treatise on Architecture�), which describes an ideal Renaissance city  called Sforzinda. Among the projects he envisioned was a tower of vice  and virtue, with a brothel on the 1st floor and an astronomical observa�  tory on the 10th.</p><p>filarial worm Any of a group of parasitic nematodes that usually  require two hosts to complete the life cycle: an arthropod and another  animal, which is bitten by the arthropod. The female worm produces large  numbers of microscopic, active embryos, called microfilariae, that pass  into the bloodstream of the primary host. These enter the body of an insect  when it bites the infected animal; within the insect the microfilariae grow  into larvae, which are passed to an animal the insect bites, where they  complete their growth. See also heartworm.</p><p>filbert or hazel (nut) Any of about 15 species of deciduous trees and  shrubs that make up the genus Corylus, in the birch family, native to the  northern temperate zone; also, the edible nuts they produce. Choice nuts  are produced by two Eurasian trees, the European filbert (C. aveliana)  and the giant filbert (C. maxima), and by hybrids of these species. Some  varieties are valuable hedgerow and ornamental trees. An oil from C.  avellana is used in food products, perfumes, and soaps; the tree yields a  soft, reddish-white timber that is useful for small articles such as tool  handles and walking sticks.</p><p>file In hardware and metalworking, bar- or rod-shaped tool of hardened  steel with many small cutting edges raised on its surfaces. Files are used  for smoothing or forming objects, especially of metal. A file�s cutting or  abrading action results from rubbing it, usually by hand, against the work-  piece. The single-cut file has rows of parallel teeth cut diagonally across  the working surfaces. The double-cut file has rows of teeth crossing each  other. Rasp teeth are disconnected and round on top; rasp files are usu�  ally very coarse and are used primarily on wood and soft materials.</p><p>file transfer protocol See FTP</p><p>filibuster Tactic of delaying action on a bill by talking long enough to  wear down the majority in order to win concessions or force withdrawal  of the bill. The tactic is normally employed by a group that cannot mus�  ter enough votes to defeat a bill by vote. Filibustering is possible in the  U.S. Senate because Senate rules allow unlimited debate on a bill. A fili�  buster may be carried out by a group or a single member, and the speech  need not be related to the bill under discussion. Calling for a vote to limit  debate (cloture)�which requires 60 votes, the votes of three-fifths of the  entire membership, in the U.S. Senate�or holding around-the-clock ses�  sions to tire the speakers are measures used to defeat filibusters.</p><p>Fillmore, Millard (b.

Though he abhorred slavery,  he supported the Compromise of  1850 and insisted on federal  enforcement of the Fugitive Slave Act.</p><p>His stand, which alienated the North, led to his defeat by Winfield Scott  at the Whigs� nominating convention in 1852. He was an early champion  of U.S. commercial expansion in the Pacific. In 1853 he sent Matthew  Perry with a fleet of warships to Japan to force its isolationist government  to enter into trade and diplomatic relations. He returned to Buffalo and  was nominated for president by the Know-Nothing Party in 1856.</p><p>film See MOTION PICTURE</p><p>film noir \'nwar\ French "dark film" Film genre that offers dark or  fatalistic interpretations of reality.

As the crystals grow and accumulate in magma, a crystal mesh may be  formed. Pressure applied by the weight of crystals above or by outside  forces may force the more mobile liquid out of the mesh and also may  fracture or crush the remaining crystals. Filter-pressing has been used to  explain the formation of rocks consisting of only one kind of mineral.</p><p>fin whale or finback whale or razorback whale or common  rorqual Vror-kwolV Swift, slender-bodied baleen whale ( Balaenoptera  physalus) named for the ridge on its back. It is 59-89 ft (18-27 m) long,  with a triangular dorsal fin, short baleen, and several dozen grooves along  its throat and chest. It is gray, with white on the underparts and on the  right side of the lower jaw. It is found in oceans worldwide, in groups of  a few to several hundred. It lives in polar waters in summer, feeding on  crustaceans and small fishes, and moves to warmer waters in winter to  breed. Once commercially valuable, it has been substantially reduced in  numbers by overhunting and is now listed as an endangered species.</p><p>finance Process of raising funds or capital for any kind of expenditure.  Consumers, business firms, and governments often do not have the funds  they need to make purchases or conduct their operations, while savers  and investors have funds that could earn interest or dividends if put to  productive use. Finance is the process of channeling funds from savers  to users in the form of credit, loans, or invested capital through agencies  including commercial banks, savings and loan associations, and such non�  bank organizations as credit unions and investment companies. Finance  can be divided into three broad areas: business finance, personal finance,  and public finance. All three involve generating budgets and managing  funds for the optimum results. See also corporate finance.</p><p>finance company Specialized financial institution that supplies credit  for the purchase of consumer goods and services. Finance companies pur�  chase unpaid customer accounts at a discount from merchants and collect  payments due from customers.

Finches are small, compact birds 3-10 in.  (10-27 cm) long. Most use their heavy bill to crack seeds; many also eat  insects. Many finches are brightly coloured, often with shades of red and  yellow. Found throughout the temperate areas of the Northern Hemisphere  and South America and in parts of Africa, finches are among the domi�  nant birds in many areas, both in numbers of individuals and species. They  are often kept as singing cage birds.</p><p>Fine Gael Vfe-no-'gaH Irish "Gaelic Nation" Major political party  in Ireland, also known as United Ireland Party.

It held power  briefly in 1948, but Fianna Fail dominated Irish politics until 1973. From  the mid-1970s, both Fine Gael and Fianna Fail vied for power in com�  petitive elections, with Fine Gael forming several coalition governments.</p><p>finery process Early method of converting cast iron to wrought iron,  superseding the bloomery process after blast furnaces became widespread.  Pieces of cast iron (see pig iron) were placed on a finery hearth, on which  charcoal was being burned with a plentiful supply of air, so that carbon  in the iron was removed by oxidation, leaving semisolid malleable iron  behind. From the 15th century on, this two-stage process gradually  replaced direct making of malleable iron. It was in turn replaced by the  PUDDLING PROCESS.</p><p>Finger Lakes Group of narrow, glacial lakes, western New York state,  U.S. They lie in north-to-south valleys between Syracuse and Geneseo.

Seneca Lake, the largest in the group, is 67 sq mi (174 sq  km).</p><p>fingerprinting Act of taking an impression of a person�s fingerprint.  Because each person�s fingerprints are unique, fingerprinting is used as a  method of identification, especially in police investigations. The standard  method of fingerprint classification was developed by Sir Francis Galton  and Sir Edward Henry; their system was officially introduced at Scotland  Yard in 1901. The U.S. Federal Bureau of Investigation maintains a finger�  print file on more than 250 million people; fingerprints retrieved from a  crime scene may be compared with those on file to identify suspects. DNA  analysis, which examines regions of DNA unique to each person, is some�  times called DNA fingerprinting.</p><p>Fink, Mike (b. 1770/80, Fort Pitt, Pa.�d. 1823, Fort Henry?

Capital: Helsinki. The majority of the people are Finns; there is a small  Sami (Lapp) population in Lapland. Languages: Finnish and Swedish are  both �national� languages; the Sami speak a Finno-Ugric language. Reli�  gion: Christianity (predominantly Protestant; also Eastern Orthodox).  Currency: euro. Finland is one of the world�s most northern and geo�  graphically remote countries, about one-third of it lying north of the Arc�  tic Circle. Heavily forested, it contains thousands of lakes, numerous  rivers, and extensive areas of marshland. Except for a small highland  region in the extreme northwest, Finland�s relief doesn�t vary greatly. The  south has relatively mild weather; the north has severe and prolonged  winters and short summers. Finland has a developed free-market economy  combined with state ownership of a few key industries. It is among the  wealthiest countries in Europe and in the world. Lumbering is a major  industry, and manufacturing is highly developed; service industries are  also notable. Finland is a republic with one legislative house; its chief of  state is the president, and the head of government is the prime minister.  Archaeological discoveries have led some to suggest that human habita�  tion in Finland dates back at least 100,000 years. Ancestors of the Sami  apparently were present in Finland by about 7000 bc. The ancestors of the  present-day Finns came from the southern shore of the Gulf of Finland  in the 1st millennium bc. The area was gradually Christianized from the  11th century ad. From the 12th century Sweden and Russia contested for  supremacy in Finland, until in 1323 Sweden ruled most of the country.  Russia was ceded part of Finnish territory in 1721; in 1808 Alexander I of  Russia invaded Finland, which in 1809 was formally ceded to Russia.

Finnish was an unwritten language until the 16th century,  when Mikael Agricola (1509-57) produced an alphabet book (1543) and  a translation of the New Testament (1548); he is regarded as the founder  of the Finnish literary language. Finnish was accorded official status in  1809, when Finland entered the Russian Empire after six centuries of  Swedish domination. The publication in 1835 of the national folk epic,  the Kalevala, created from folk songs collected by Elias Lonnrot, gave  increased impetus to the movement to forge a common national language  encompassing all dialect areas. Finnish shares with other Baltic Finnic  languages a stock of ancient loanwords from Germanic, Baltic, Slavic, and  Sami.</p><p>Finno-Ugric \'yu-grik\ languages Branch of the Uralic language  family spoken by about 25 million people in northeastern Europe, north�  ern Asia, and (through immigration) North America.

The latter consists of two  language complexes of western Siberia, Khanty and Mansi, spoken by  fewer than 15,000 people. The Finnic branch comprises the Sami (Saami,  Lappish) languages, the Baltic Finnic languages, Mordvin, Mari, and the  Permic languages. Sami is spoken by some 20,000 people in northern  Scandinavia and adjacent Russia. Baltic Finnic comprises Finnish, Esto�  nian (with 1.1 million speakers worldwide), and a string of declining lan�  guages in Latvia and Russia. Mordvin is spoken by 1.1 million people in  scattered enclaves of central European Russia. Mari is also spoken in cen�  tral Russia and in scattered areas east toward the Ural Mountains; its two  major varieties have about 600,000 speakers. The Permic languages,  spread over a broad swath of northeastern European Russia, comprise  Udmurt (spoken by some 500,000 people) and Komi (spoken by fewer  than 400,000 people but with two literary forms). Finno-Ugric languages  written in Russia use variants of the Cyrillic alphabet, while those outside  Russia use the Latin alphabet.</p><p>Finno-Ugric \ l fi-no- , yii-grik\ religion Pre-Christian belief systems of  the Finno-Ugric peoples, who lived in northern Scandinavia, Siberia, the  Baltic region, and central Europe. Surviving Finno-Ugric groups include  the Sami (Lapps), Finns, Estonians, and Magyars. The geographic and cul�  tural diversity of these peoples led to the evolution of varying religious  beliefs. The most common Finno-Ugric creation myth is the earth-diver  myth, in which the Devil is forced to dive into the sea and gather sand,  from which God forms the earth. Another myth tells of the creation of the  world from a cosmic egg. The chief deities usually included a sky god  and an earth mother. While the major gods were remote, there were guard�  ian spirits at hand to regulate daily life; they resided in households, natu�  ral sites such as lakes and forests, and natural phenomena such as wind  or fire. Ancestor worship was practiced. Religious functionaries included  shamans, sacrificing priests, guardians of the sanctuary, professional  weeping women, and performers of wedding ceremonies. Cult centres  ranged from home sanctuaries to sacred groves and sacrificial stones.</p><p>Fionn cycle See Fenian cycle  fiord See fjord</p><p>Fiordland Vfy6rd-,land\ National Park Park, southern South Island,  New Zealand.

Many other evergreen conifers (e.g., Douglas fir, hemlock  fir) are also commonly called firs. True firs are native to North and Central  America, Europe, Asia, and northern Africa. They are distinguished from  other genera in the pine family by their needlelike leaves, which grow  directly from the branch and have bases, shaped like suction cups, that  leave conspicuous circular scars when the leaves fall. North America  boasts 10 native species of fir, found chiefly from the Rocky Mountains  westward. The wood of most western North American firs is inferior to that  of pine or spruce but is used for lumber and pulpwood. Of the two fir species  that occur in the eastern U.S. and Canada, the better known is the balsam  fir (A. balsamea ), a popular ornamental and Christmas tree.</p><p>Firdusi See FerdowsT</p><p>fire Rapid burning of combustible material, producing heat and usually  accompanied by flame. For eons, lightning was the only source of fire.  The earliest controlled use of fire seems to date to c. 1,420,000 years ago,  but not until c. 7000 bc did Neolithic humans acquire reliable firemaking  techniques, including friction from hardwood drills and sparks struck  from flint against pyrites. Fire was used initially for warmth, light, and  cooking; later it was used in fire drives in hunting and warfare, and for  clearing forests of underbrush to facilitate hunting. The first agricultural�  ists used fire to clear fields and produce ash for fertilizer; such �slash-  and-burn� cultivation is still used widely today. Fire also came to be used  for firing pottery and for smelting bronze (c. 3000 bc) and later iron (c.  1000 bc). Much of the modern history of technology and science can be  characterized as a continual increase in the amount of energy available  through fire and brought under human control.</p><p>fire ant Any of a genus ( Solenopsis ) of insects in the ant family, several  species of which are common in southern North America. They are red or  yellowish and can inflict a severe sting. The semipermanent nest consists of  a loose mound with open craters for ventilation. The workers (see caste) are  notorious for damaging planted grain and attacking poultry.</p><p>fire escape Means of rapid egress from a building, primarily intended  for use in case of fire. Building codes define an exit as an enclosed and  protected path of escape in the event of a fire, leading from an exit access  through a combination of corridors, stairways, and doors to an exit dis�  charge at an exterior court or public way. The term fire escape usually  refers to open iron or steel balconies with steep stairways on the outside  of buildings; often a retrofit of older buildings, these are rare in new con�  struction. Other means of escape are by balconies leading to adjacent  buildings, or through chutes, often used in hospitals.</p><p>Fire Island Elongated sandspit, off the southern shore of Long Island,  New York state, U.S. The island measures 32 mi (51 km) long and 0.5  mi (1 km) at its widest, and its name refers to fires that were built there  as signals to ships during the War of 1812; a lighthouse was built at its  western tip in 1858. Now a popular summer resort, it is connected to Long  Island by two bridges and by ferry. Fire Island (now Robert Moses) State  Park was opened in 1908, and a 19,000-acre (7,700-hectare) section of  the island was dedicated as a national seashore in 1964.</p><p>fire walking Religious ceremony that involves walking across hot  coals, red-hot stones, or burning wood. It has been practiced in many parts  of the world, including ancient Greece, India, Japan, China, Tahiti, New  Zealand, Bulgaria, and Spain. The most common form of fire walking  involves striding across a layer of embers spread thinly over the bottom  of a shallow trench. More rarely, devotees may walk through a blazing  log fire. The reasons for fire walking include purification and as an ordeal  to prove innocence. Devotees believe that only those who lack faith will  be burned, and many fire walkers do escape without injury.</p><p>firefly or lightning bug Any of the nocturnal luminous beetles of the  family Lampyridae, consisting of about 1,900 species that inhabit tropi�  cal and temperate regions (including the common glowworm). Adult fire�  flies are 0.2-1 in. (5-25 mm) long and have light-producing organs on the  underside of the abdomen. The soft, flattened, dark-brown or black body  is often marked with orange or yellow. Some adult fireflies do not eat;  others feed on pollen and nectar. Most fireflies produce short, rhythmic  flashes in a pattern that is characteristic of the species and an important  mating signal.</p><p>fireplace Opening made in the base of a chimney to hold an open fire.  The opening is framed, usually ornamentally, by a mantel (or mantel�  piece). A medieval development that replaced the open central health for</p><p>heating and cooking, the fireplace was sometimes large enough to accom�  modate a sitting space called an inglenook. Early fireplaces were made  of stone; later, brick came into use. In 1624 Louis Savot developed a fire�  place in which air was drawn through passages under the hearth and dis�  charged into the room through a grill, a design adapted in the 20th century.</p><p>fireproofing Use of fire-resistant materials in a building to prevent  structural collapse and allow safe egress of occupants in case of fire. The  fire-resistive ratings of various materials and constructions are established  by laboratory tests and usually specified in terms of hours a material or  assembly can be expected to withstand exposure to fire. Building codes  require application of cementitious material or insulation to structural  steel frames, fire-resistant construction (e.g., using concrete block) of  enclosures around exits, flame-spread ratings of finish materials such as  carpeting and wall coverings, and use of such inherently fire-resistant  materials as reinforced concrete and heavy timber.</p><p>Firestone, Harvey S(amuel) (b. Dec. 20, 1868, Columbiana, Ohio,  U.S.�d. Feb. 7, 1938, Miami Beach, Fla.) U.S. industrialist. Firestone  established a retail tire business in 1896 and in 1900 formed a company to  sell rubber carriage tires. In 1904 his business began manufacturing auto�  mobile tires. Sales to Ford Motor Co. helped put Firestone Tire and Rubber  Co. at the top of the U.S. tire industry. Firestone promoted the use of trucks  for hauling freight and lobbied for the construction of vast highway sys�  tems. He ran his company until 1932, when his son replaced him. Firestone  was purchased by Bridgestone Tire Co., a Japanese firm, in 1988.</p><p>firewall Computer security system that controls the flow of data from  one computer or network to another. Firewalls are mainly intended to pro�  tect the resources of a private network from being directly accessed by a  user from an external network, especially via the Internet. Users inside  the private network may also be prevented from directly accessing exter�  nal computers. To accomplish this, all communications are routed through  a �proxy server� that determines whether a message or file will be allowed  to enter or exit the private network.</p><p>fireweed Perennial wildflower (Epilobium angustifolium) of the  evening-primrose family. Its spikes of whitish to magenta flowers, which  grow up to 5 ft (1.5 m) high, can be a spectacular sight on prairies of the  temperate zone. Its seeds can lie dormant for many years, awaiting the  warmth necessary for germination. Fireweed is one of the first plants to  appeal' after a forest or brush fire; it also rapidly covers scrub or wood�  land areas that have been cleared by machine. It has limited use in wild  gardens, where it must be carefully checked and confined.</p><p>fireworks Explosives or combustibles used for display. Of ancient Chi�  nese origin, fireworks evidently developed out of military rockets and  explosive missiles and accompanied the spread of military explosives  westward to Europe in the Middle Ages. In force-and-spark compositions,  potassium nitrate, sulfur, and ground charcoal are used; additional ingre�  dients produce various types of sparks. In flame compositions, such as the  stars that shoot out of rockets, potassium nitrate, salts of antimony, and  sulfur may be used; for coloured fire, potassium chlorate or perchlorate  is combined with a metal salt that determines the colour. Rockets are lifted  by recoil from the jet of fire thrown out by the burning composition.</p><p>first cause In philosophy, the uncreated or self-created cause to which  every series of causes must ultimately be traced. Used by ancient Greek  thinkers, the concept was adopted by the Christian tradition and became  the basis of one version of the cosmological argument for the existence of  God. According to this argument, every observed event is the result of a  series of causes that must end in a first cause, which is God. The argu�  ment was given its classic formulation by St. Thomas Aquinas. It was  rejected by many later thinkers, including David Hume and Immanuel Kant.</p><p>First International officially International Working Men's  Association Federation of workers� groups, founded in 1864 by Brit�  ish and French trade-union leaders. Its structure was highly centralized,  based on local groups that were integrated into national federations. It  was split by conflicting schools of socialist thought, including those of  Karl Marx, Pierre-Joseph Proudhon, Louis-Auguste Blanqui, and Mikhail  Bakunin. A clash between Marx�s centralized socialism and Bakunin�s  anarchism in 1872 caused the International to split, and it was dissolved  in 1876. Though it was feared at the time as a formidable power with  millions of members, and several countries tried to have it outlawed, its  membership was never more than 20,000 and it served mainly as a uni�  fying force for labour in Europe.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>first lady &#x25BA; fish hawk I 677</p><p>first lady Wife of the president of the U.S. Although the first lady�s role  has never been codified or officially defined, she figures prominently in  the country�s political and social life. Representative of her husband on  official and ceremonial occasions both at home and abroad, the first lady  is closely watched for some hint of her husband�s thinking and for a clue  to his future actions. The wife of the president played a public role from  the founding of the U.S., but the title first lady did not come into general  use until much later, near the end of the 19th century. By the end of the  20th century, the title had been absorbed into other languages and was  often used, without translation, for the wife of a country�s leader�even  in countries where the leader�s consort received far less attention and  exerted much less influence than did her counterpart in the U.S. Although  unpaid and unelected, she is able to influence behaviour and opinion, and  some first ladies have used their influence to affect legislation on impor�  tant matters such as temperance reform, housing improvement, and wom�  en�s rights.</p><p>FIS See Islamic Salvation Front</p><p>Fischer-Dieskau Vfi-shor-'des-.kauX, Dietrich (b. May 28, 1925, Ber�  lin, Ger.) German baritone and conductor. He had his first extensive per�  formance experience as a prisoner of war in Italy, and he made his  professional debut in 1947. One of the most remarkable singers of his  time, he was equally successful in the often mutually exclusive realms of  opera and lied. His lyrical voice was supported by his commanding pres�  ence, intelligent musicianship, and superb artistry. He recorded most of  the standard art-song repertoire, as well as numerous unusual and con�  temporary works; his many premieres included Benjamin Britten�s War  Requiem (1962).</p><p>fiscus Latin "basket" Treasury of the Roman emperor, so-called  because the money was stored in baskets. Funds were also stored in the  public treasury, the aerarium. The fiscus took in taxes from imperial prov�  inces, forfeited property, and unclaimed lands. After Vespasian, it became  independent of the aerarium and controlled most of the empire�s income,  supplying funds for the army and fleet, official salaries, and postal sub�  sidies.</p><p>fiscal policy Measures employed by governments to stabilize the  economy, specifically by adjusting the levels and allocations of taxes and  government expenditures. When the economy is sluggish, the government  may cut taxes, leaving taxpayers with extra cash to spend and thereby  increasing levels of consumption. An increase in public-works spending  may likewise pump cash into the economy, having an expansionary effect.  Conversely, a decrease in government spending or an increase in taxes  tends to cause the economy to contract. Fiscal policy is often used in tan�  dem with monetary policy. Until the 1930s, fiscal policy aimed at main�  taining a balanced budget; since then it has been used �countercyclically,�  as recommended by John Maynard Keynes, to offset the cycle of expan�  sion and contraction in the economy. Fiscal policy is more effective at  stimulating a flagging economy than at cooling an inflationary one, partly  because spending cuts and tax increases are unpopular and partly because  of the work of economic stabilizers.

He determined the structures of uric acid, caffeine, and  related compounds, showing that all are derivatives of a single compound  he named purine. This led him to study protein structure and the ways in  which amino acids are combined in proteins. He determined the molecu�  lar structures of glucose, fructose, and many other sugars, verifying his  results by synthesizing each, and distinguished the 15 stereoisomers of  glucose (see isomer; configuration; optical activity). His researches into the  sugars were of unparalleled importance to organic chemistry and earned  him in 1902 the second Nobel Prize for Chemistry.

Fishing is as old as the  human ability to use tools to capture prey. The first significant modem  innovations, including use of a reel, a rod with line guides, and a hook  with an offset point, came in the late 17th and early 18th centuries. Horse�  hair was used as line until the mid 19th century, when it was replaced by  textile materials; these in turn were replaced by nylon in the 1930s. Wood  and bamboo rods yielded to rods of fibreglass and other synthetic mate�  rials. Forms of sport fishing practiced today include fly fishing (freshwa�  ter), in which a fly-like hook is repeatedly cast upon the water surface to  attract biting fish; bait fishing (fresh- and saltwater), in which live or arti�  ficial bait is set or drawn below the surface; and big-game fishing (salt�  water), in which heavy-duty tackle is used to land large marine species  (including tuna, marlin, and swordfish) from a motorized boat.</p><p>fishing industry Taking, processing, and marketing of fish and other  seafood from oceans, rivers, and lakes.

The fission results in radiation damage,  or fission tracks, that can be made visible by preferential leaching  (removal of material by solution) of the host substance with a suitable  chemical reagent; the leaching process allows the etched fission-track pits  to be viewed and counted under a microscope. The amount of uranium  present can be determined by irradiation that produces thermal fission of  uranium-235, which produces another population of tracks, related to the  uranium concentration of the mineral. Thus, the ratio of naturally pro�  duced, spontaneous fission tracks to induced fission tracks is a measure  of the age of the sample.

The term may  be used to describe insurrection or civil warfare or, more specifically, to  define a tribunal over doctrinal issues, broadly similar to the Christian  Inquisition. There were four fitnahs in the early history of Islam. The first  (656-661) followed the murder of the third caliph, 'Uthman ibn �Affan. It  brought up the question of 'All�s right to rule and prompted a military con�  flict that eventually resulted in the schism between the Sunnite and the  ShTite branches. The second coincided with the caliphate of Yazid I (680-  683); it was a continuation of the struggle between claimants to the caliph�  ate and led to the death of al-HusAYN ibn c AlT at the Battle of Karbala 5 �  another formative event in the Sunnite-Shfite split. The third fitnah (744-  750) resulted in the ascendancy of the 'Abbasid dynasty.

Chinese stu�  dents usually studied the shorter Four Books before attempting the Five  Classics, which consist of the Yijing (�Classic of Changes�), the Shujing  (�Classic of History�), the Classic of Poetry, the Collection of Rituals,  and the Chunqiu (�Spring and Autumn Annals�). The Five Classics were  taught from 136 bc (when Confucianism became the state ideology of  China) until the early 20th century. Proficiency in the texts was required  for any scholar applying for a post in the vast government bureaucracy.  After 1950 only select texts were taught in public schools. See Chinese  EXAMINATION SYSTEM.</p><p>Five Dynasties Period in Chinese history betweeen the fall of the Tang  dynasty (907) and the founding of the Song dynasty (960), when five  would-be dynasties (the Hou Liang, the Hou Tang, the Hou Jin, the Hou  Han, and the Hou Zhou) followed one another in quick succession in  northern China. The period is also called the Ten Kingdoms because of  the 10 regimes that dominated separate regions of southern China in the  same period. Though unstable politically, culturally it was a period of  great accomplishment. Printing with wooden blocks was fully developed;  the first complete printing of the Confucian Classics was completed in  953. The form of lyric poetry called ci {tz�u) flourished, and flower paint�  ing, previously distinctively Buddhist, became a branch of nonreligious  painting.</p><p>Five Pecks of Rice Daoist-inspired popular movement that occurred  near the end of China�s Han dynasty (206 bc-ad 220) and greatly weak�  ened the government. It became a prototype of the religiously inspired  popular rebellions that were to erupt periodically in China throughout its  history. Its founder, Zhang Daoling, is considered the first patriarch of the  Daoist church in China. He was originally a faith healer, and the move�  ment�s name came from the five pecks of rice a year that clients paid him  for their cure or as dues to the cult. During a time of poverty and misery,  Zhang�s grandson Zhang Lu set up an independent theocratic state that  grew to encompass all of present-day Sichuan province. In ad 215 Zhang  Lu surrendered to Cao Cao.

In the Soviet Union, the first Five-Year Plan</p><p>(1928-32), implemented by Joseph Staun, concentrated on developing  heavy industry and collectivizing agriculture, at the cost of a drastic fall  in consumer goods. The second plan (1933-37) continued the objectives  of the first. Collectivization led to terrible famines, especially in the  Ukraine, that caused the deaths of millions. The third (1938-42) empha�  sized the production of armaments. The fourth (1946-53) again stressed  heavy industry and military buildup, angering the Western powers. In  China, the first Five-Year Plan (1953-57) stressed rapid industrial devel�  opment, with Soviet assistance; it proved highly successful. Shortly after  the second plan began in 1958, the Great Leap Forward was announced;  its goals conflicted with the five-year plan, leading to failure and the  withdrawal of Soviet aid in 1960.</p><p>fjord or fiord \fe-'ord\ Long, narrow arm of the sea, often extending  well inland, that results from marine  inundation of a glaciated valley.</p><p>Many fjords are remarkably deep; it  is assumed that the huge glaciers that  formed in these valleys were so  heavy that they eroded the bottoms  of the valleys far below sea level.</p><p>After the glaciers melted, the waters  of the sea invaded the valleys.</p><p>flag Combination of symbols repre�  sented on a piece of cloth, serving as  a medium of social, typically politi�  cal, communication. It is usually  rectangular and attached by one edge  to a staff or is hoisted on a pole with  halyards. Flags appear to be as old as  civilized human society, though their  origin is not well understood. The  Chinese may have been the first to develop cloth flags, and it is believed  that they were introduced to Europe by returning Crusaders. Most national  flags in use today were designed in the 19th and 20th centuries.</p><p>flagellants Vfla-ja-lantsV Medieval religious sects that included public  beatings with whips as part of their discipline and devotional practice.  Flagellant sects arose in northern Italy, and had become large and wide�  spread by c. 1260. Groups marched through European towns, whipping  each other to atone for their sins and calling on the populace to repent.  They gained many new members in the mid-14th century while the Black  Death was ravaging Europe. Though periodically suppressed by the  authorities, flagellant sects enjoyed sporadic resurgences into the 16th  century.</p><p>Bradshaw Sound, Fiordland, west coast  of South Island, New Zealand</p><p>COURTESY OF THE NEW ZEALAND GEOLOGICAL SURVEY;  PHOTOGRAPH, T.

July  12, 1895, Hamar, Nor.�d. Dec. 7, 1962, Oslo) Norwegian soprano. Bom  to musician parents, she made her operatic debut in 1913. In 1934 she  sang Sieglinde in Die Walkiire and Gutrune in Gotterdammerung at  Bayreuth. Recognized as the greatest Wagnerian soprano of her genera�  tion, she made her Metropolitan Opera debut in 1935. With New York as  her base, she toured widely until 1941, returning to Norway to be with  her husband, a member of Vidkun Quisling�s government. Though cleared  of charges of collaboration with the Germans, her later U.S. appearances  were controversial. She was the first director of the Royal Norwegian  Opera (1958-60).</p><p>Flaherty Vfla-sr-te, 'fla-3r-te\, Robert (Joseph) (b. Feb. 16, 1884,  Iron Mountain, Mich., U.S.�d. July 23, 1951, Dummerston, Vt.) U.S.  filmmaker, considered the father of the documentary. He grew up in remote  northern Canada and later led explorations of the area (1910-16). He lived  with the Eskimos for 16 months and filmed their way of life. His result�  ing film, Nanook of the North (1922), was an international success and  established the model for the documentary film. His later documentaries  include Moana (1926), Tabu (1931), Man of Aran (1934), The Land  (1942), and Louisiana Story (1948).</p><p>flake tool Stone Age devices, usually flint (see chert and flint), shaped  by flaking off small particles or by breaking off a large flake to use as a  tool. Prehistoric humans preferred flint and similar siliceous stones  because of the ease with which they could be chipped and for their sharp  cutting edges. They also used sandstones, quartzites, quartz, obsidian, and  volcanic rocks. Stone tools were chipped by striking a block of flint with  a hammer of stone, wood, or bone or by striking the block itself on the  edge of a fixed stone. Pressure flaking consists of applying pressure by  means of a pointed stick or bone near the edge of a flake or blade, to  detach small flakes, and was used mostly to put the finishing touches on  tools. See also stone-tool industry.</p><p>Flamboyant style Phase of late Gothic architecture in 15th-century  France and Spain. It evolved out of the Rayonnant style's increasing  emphasis on decoration. Its most conspicuous feature is the dominance  in stone window tracery of a flamelike S-shaped curve. Wall surface was  reduced to the minimum to allow an almost continuous window expanse.  Structural logic was obscured by covering buildings with elaborate trac�  ery. Attractive French examples include Notre-Dame d�Epine near  Chalons-sur-Mame, Saint-Maclou in Rouen (c. 1500-14), and the north�  ern spire of Chartres Cathedral. Spanish Flamboyant architects developed  their own intricate forms of vaulting with curvilinear patterns; the Capilla  del Condestable in Burgos Cathedral (1482-94) and Segovia Cathedral  (begun 1525) provide examples. Flamboyant Gothic, which became  increasingly ornate, gave way in France to Renaissance forms in the 16th  century.</p><p>f la men Vfla-monV One of 15 priests in ancient Rome, each of whom  was devoted to the service of a specific god. The most important were  those who served Jupiter, Mars, and Quirinus. Chosen from the patrician  class and supervised by the pontifex maximus (chief priest), they offered  daily sacrifices and led strictly regulated lives. Their wives assisted them  and were also bound by ritual regulations. In imperial times a group of  famines were devoted to the worship of deified emperors.</p><p>flamenco UJo-'meq-koV Form of song, dance, and instrumental (mostly  guitar) music commonly associated with the Andalusian RoMa (Gypsies)  of southern Spain. (There, the Roma people and their language are known  as Calo, or Gitano.) The roots of flamenco, though somewhat mysterious,  seem to lie in the Roma migration from Rajasthan (in northwest India) to  Spain between the 9th and 14th centuries. Its essence is cante, or song,  often accompanied by guitar music and improvised dance. The cante  jondo (�profound song� or �deep song�), thought to be the oldest form,  is characterized by profound emotion and deals with themes of death,  anguish, despair, or religious doubt. After the mid-19th century, flamenco  song was usually accompanied by guitar music and a palo seco (Span�  ish: �dry stick,� a stick that was beat on the floor to keep time) and a  dancer performing a series of choreographed dance steps and improvised  styles. Baile, or dance, has been the dominant element of flamenco since  that time, though it is never performed without accompaniment. Essen�  tial to traditional flamenco is the duende, an intensely focused, trancelike  state of transcendent emotion. It is usually enhanced by rhythmic hand  clapping and encouraging interjections (jaleo ) from fellow performers.</p><p>flamethrower Military assault weapon that projects a stream of blaz�  ing oil or gasoline against enemy positions. It consists of one or more fuel  tanks, a cylinder of compressed gas to supply the propelling force, and a  flexible hose with a trigger-nozzle that ignites and sprays the fuel. Por�  table flamethrowers are carried on the backs of ground troops; larger units  may be installed on tank turrets. Modern flamethrowers, first used in  combat in World War I, were used by all major powers in World War II  and later wars. They are often used in areas of dense underbrush and  against fortified positions at close range.</p><p>flamingo Any of five species of tall wading birds constituting the fam�  ily Phoenicopteridae. The plumage is mainly pink, and the face is bare.  Flamingos have webbed feet, a slender body, a long thin neck, large wings,  and a short tail. They are about 3-5 ft (90-150 cm) tall. Flamingos flock  by the hundreds (sometimes by the millions) in flight formations and  wading groups. They walk the shallows, stirring up organic matter, espe�  cially tiny mollusks and crustaceans, which they strain from the muddy  water with their sievelike bills. The various species are found along Atlan�  tic and Gulf coasts of tropical and subtropical North America and in South  America, Africa, southern Europe, Asia, Madagascar, and India.</p><p>Flamininus N.flam-s-'nl-e-nosV Titus Quinctius (b. c. 227 bc �d.  174) Roman general and consul (198 bc). As consul he tried to formulate  a peace treaty with Philip V of Macedonia, but negotiations broke down  and fighting broke out. He defeated Philip at Cynoscephalae (197) and  granted freedom to the Greeks (196), for which he was hailed as a sav�  iour. He kept Roman troops in Greece until 194. After the defeat of Anti-  ochus III and Aetolia at Thermopylae (191), he helped reestablish peace  in Greece.</p><p>Flaminius Vfta-'min-e-osV Gaius (d. 217 bc) Roman political leader.  As tribune (232) he supported Roman expansion in northern Italy; his land  bill (232) gave land to Roman plebeians and gained him great popularity,  but the bill�s passage was seen as the cause of the Gallic invasion of 225  (repelled in 223), and he was held responsible. He was elected consul in  223 and 217. As censor (220) he built the Circus Flaminius in Rome and  the Via Flaminia to Ariminum (Rimini). He died fighting Hannibal in the  Second Punic War.</p><p>Flanders Flemish Vlaanderen Vvlan-do-ronV Medieval principality  extending along the coast of the Low Countries. Its lands are now included  in the French departement of Nord, the Belgian provinces of East Flanders  and West Flanders, and the Dutch province of Zeeland. Ruled by Bald�  win I in 862, Flanders began to grow as a commercial centre, fostered by  its strategic location between the Mediterranean Sea and the Scandina�  vian and Baltic countries. It passed to Burgundy in 1384 and then to the  Austrian Habsburgs in 1477. It remained part of the Netherlands under  Spanish rule in the 17th century. It was the scene of fighting during both  World War I and World War II. Limited autonomy was granted to Bel�  gian Flanders in the 1980s, and it became one of the three regions in the  new federation of Belgium in 1993.</p><p>Flandin \fla n -'da n \, Pierre-Etienne (b. April 12, 1889, Paris,  France�d. June 13, 1958, Saint-Jean-Cap-Ferrat) French politician. He  served in the Chamber of Deputies (1914-40) and held various ministe�  rial posts in the Third Republic, serving briefly as premier (1934-35). As  foreign minister when the Germans marched into the Rhineland in 1936,  he failed to convince the French and British governments to act and  accepted German dominance, though when he returned briefly as foreign  minister in the Vichy regime, he resisted German demands. Later charged  with treason, he was acquitted in 1946.</p><p>flare star Star that varies in brightness repeatedly but sporadically,  sometimes by more than one magnitude, within a few minutes.

Flat�  fishes are carnivorous bottom dwellers that habitually rest on one side,  often partly buried in the sand or mud. Some can also change colour to  blend with their surroundings. Both eyes are on one side of the head. The  eyed side of the fish (uppermost as it lies on the bottom) is pigmented,  but the lower, blind side is normally white. Species vary from 4 in. (10  cm) to 7 ft (2 m) long, and some (e.g., the Atlantic halibut) may weigh as  much as 720 lb (325 kg). Many species are highly valued as food. See  also plaice; sole.</p><p>flatfoot Congenital or acquired flatness of the arch of the foot, in which  the foot and heel usually also roll outward, resulting in a splayfooted  position. Initially, it may result from ligament stretching and muscle weak�  ness. Later, altered shape of the bones may make the deformity rigid. In  a few cases it seems to result from excessive weight or an injury. Symp�  toms may include pain, spasm, and awkward gait, but many patients have  no disability or pain. Treatment to correct arch and heel position employs  proper shoes and muscle strengthening; arch supports are indicated only  for severe pain or excessive fatigue.</p><p>Flathead North American Indian people living in Montana, U.S. Salish  is what they call themselves, and their language is of Salishan linguistic  stock. The name Flathead is now customary, although it is a misnomer; they  themselves did not practice head-flattening, but some of their slaves came  from tribes that did. The Flatheads, who inhabited what is now western  Montana, were the easternmost group of the Plateau Indians, but they exhib�  ited many cultural traits of the Plains Indians just east over the Rocky Moun�  tains. They acquired horses and went on bison hunts on the Plains, often  warring with Plains tribes. The Plains tepee was the usual dwelling. Western  Flatheads used bark canoes, and fishing was important for all groups. Reli�  gious belief centred on guardian spirits, with whom one communicated in  visions. Since 1872 the Flatheads have resided primarily on a reservation  north of Missoula, Mont. In the 2000 U.S. census some 3,300 individuals  claimed sole Salish descent and about 3,500 Salish and Kootenoi.</p><p>Flathead River River, southeastern British Columbia, Canada, and  western Montana, U.S. Rising in the MacDonald Range, it flows south  for 240 mi (385 km) across the Canada-U.S. boundary into Montana.

The Flathead valley is  a resort region with diversified farming and fruit growing, lumbering, and  mining.</p><p>Flatt, Lester (Raymond) (b. June 19, 1914, Duncan�s Chapel, near  Sparta, Tenn., U.S.�d. May 11, 1979, Nashville, Tenn.) U.S. bluegrass  and country music guitarist and singer. He worked in textile mills until the  late 1930s, when he and his wife, Gladys, began performing as a duo. In  1945 he joined Bill Monroe�s Blue Grass Boys. There he met Earl Scruggs  (b. 1924), a native of Flint Hill, N.C., who had played banjo since age 5  and had begun playing on radio by the age of 15. Scruggs eventually per�  fected a picking technique involving the thumb and first two fingers of the  right hand that came to be called the �Scruggs style.� In 1948 the two men  left Monroe�s band to form Flatt and Scruggs and the Foggy Mountain  Boys. They made dozens of records in the 1950s and �60s and hosted their  own syndicated radio and TV shows. Scruggs�s original instrumental  compositions, including �Foggy Mountain Breakdown,� were especially  popular. They parted ways in 1969 when Scruggs joined his sons Gary and  Randy (and later Steve) in the Earl Scruggs Revue.</p><p>flatworm or platyhelminth Any of a phylum (Platyhelminthes) of  soft-bodied, usually much-flattened worms, including both free-living and  parasitic species. Flatworms live in a variety of marine, freshwater, and  terrestrial habitats worldwide. They range in length from much less than  an inch (a fraction of a millimeter) to 50 ft (15 m) and are of three main  types: turbellarians (including the planarian), trematodes (see fluke), and  cestodes (see tapeworm). Flatworms are bilaterally symmetrical and lack  respiratory, skeletal, and circulatory systems and a body cavity. Turbel�  larians are mostly free-swimming, but trematodes and cestodes are para�  sites.</p><p>Flaubert \flo-'ber\, Gustave (b. Dec. 12, 1821, Rouen, France�d.  May 8, 1880, Croisset) French novelist. Flaubert abandoned law studies  at age 22 for a life of writing. His masterpiece, Madame Bovary (1857),  a sharply realistic portrayal of provincial bourgeois boredom and adul�  tery, led to his trial (and narrow acquittal) on charges of immorality. His  other novels include the exotic Salammbo (1862), set in ancient Carthage;  A Sentimental Education (1869), a classic bildungsroman of disillusion�</p><p>ment in a time of social and political  change; and The Temptation of Saint  Anthony (1874), notable for its  depiction of spiritual torment. Trois  Contes (1877) contains three novel�  las set in the ancient, medieval, and  contemporary periods. Renowned  for his lapidary style, he is regarded  as the foremost exponent of French  REALISM.</p><p>Flavian dynasty \'fla-ve-9n\ (ad  69-96) Ancient Roman imperial  dynasty of Vespasian and his sons  Titus and Domitian, members of the  Flavia gens, or clan. Vespasian  sought to give the office of emperor  permanent form, by means of a for�  mal system of titles to replace per�  sonal names, an insistence on the  rights of office, and a move to make  Caesarism (dictatorship) hereditary  by natural descent or adoption. Wor�  ship of the deified caesars (subem�  perors) became the symbol of imperial continuity and legitimacy.</p><p>flavin \'fla-v3n\ Any of a class of organic compounds, pale yellow bio�  logical pigments that fluoresce green.

Riboflavin is the best-  known flavin.</p><p>flavonoid \ , fla-v3- l noid\ or flavone Organic compound, any member  of a class of biological pigments containing no nitrogen that are found in  many plants. They include anthoxanthins, which give yellow colours,  often to flower petals, and anthocyanins, largely responsible for the red  colouring of buds and young shoots and the purple and purple-red colours  of autumn leaves. Their biological function is unknown; they may attract  pollinators and seed dispersers.</p><p>flax family Family Linaceae (order Linales), composed of about 14  genera of herbaceous plants and shrubs found throughout the world. The  genus Linum includes flax, perhaps the most important member of the  family, grown for linen fibre and linseed oil and as a garden ornamental.  Reinwardtia species are primarily low shrubs, grown in greenhouses and  outdoors in warm climates; R. indica, yellow flax, is notable for its large  yellow flowers, borne in profusion in late fall and early winter.</p><p>Flaxman, John (b. July 6, 1755, York, Eng.�d. Dec. 7, 1826, Lon�  don) British sculptor, illustrator, and designer. In 1770 he entered the  Royal Academy schools. After 1775 he worked for pottery designer Josiah  Wedgwood, producing designs based on Classical antiquity. He directed  the Wedgwood studio in Rome (1787-94), but his book illustrations were  of far greater importance; his illustrations for the Iliad (1793), Odyssey  (1795), and Divine Comedy (1807) became very well known. The lead�  ing Neoclassical artist in England, he became the Royal Academy�s first  professor of sculpture (1810). In his own day his reputation as a sculp�  tor, notably of monuments with large groups of free-standing figures, was  exceeded only by that of Antonio Canova and Bertel Thorvaldsen.</p><p>flea Any member of 1,600 species and subspecies of small, wingless,  bloodsucking (parasitic) insects  (order Siphonaptera), found from the  Arctic Circle to the Arabian deserts.</p><p>Specialized anatomical structures  allow the flea to attach itself to the  skin of mammals or birds and con�  sume their blood. Though domestic  cats and dogs are well-known hosts,  rodents are the mammals most com�  monly afflicted by fleas. The adult  flea is 0.04-0.4 in. (1-10 mm) long  and lives from a few weeks to more  than a year. Powerful leg muscles  allow it to jump distances up to 200 times its body length. Flea infesta�  tions have had enormous consequences; fleas were the principal transmis�  sion agents of the bubonic plague in the medieval epidemics.</p><p>Gustave Flaubert, detail of a drawing  by E.F. von Liphart, 1880; in the Biblio-  theque Municipale, Rouen, France.</p><p>COURTESY OF THE BIBLIOTHEQUE MUNICIPALE, ROUEN;  PHOTOGRAPH, ELLEBE</p><p>Flea (Ctenocephalides)</p><p>WILUAM E.

While serving in  the Royal Army Medical Corps in World War I, he conducted research on  antibacterial substances that would be nontoxic to humans. In 1928 he  inadvertently discovered penicillin when he noticed that a mold contami�  nating a bacterial culture was inhibiting the bacteria�s growth. He shared  a 1945 Nobel Prize with Ernst Boris Chain and Howard Walter Florey, who  both carried Fleming�s basic discovery further in isolating, purifying,  testing, and producing penicillin in quantity.</p><p>Fleming, Ian (Lancaster) (b.

She was celebrated for her exceptional  grace and artistic expression.</p><p>Flemish art Art of the 15th to early 17th century in Flanders. The pre�  cursors of the Flemish school were located in Dijon, the first capital of the  dukes of Burgundy, who established a powerful Flemish-Burgundian politi�  cal alliance that lasted from 1363 to 1482. Philip III (the Good) moved the  Burgundian capital to Bruges and in 1425 hired Jan van Eyck as his painter.  The next generation of artists built on van Eyck�s heritage and, toward the  end of the 15th century, began looking to Italy for pictorial inspiration.  Rogier van der Weyden, Petrus Christus, Dirck Bouts, Hugo van der Goes,  Hans Memling, and Gerard David brought innovation, but little of their work  compared to van Eyck�s artistic vision. In the 16th century Pieter Bruegel the  Elder, under the influence of Hieronymus Bosch, depicted peasant life with  an eye for the grotesque. The great master of the 17th century, Peter Paul  Rubens, demonstrated unrivaled skill in oil painting; his style epitomized  the Flemish Baroque period.

In 1715 he was appointed tutor for the future Louis XV,  who later created Fleury a cardinal and minister of state (1726). Domes�  tically, Fleury restored economic and financial stability to France; in for�  eign policy, his efforts prevented the hostilities between Spain and Britain  in 1727 from becoming a European conflict. Drawn into the War of the  Polish Succession (1733-38) on the side of Stanislaw I, Louis�s father-in-  law, he was able to limit the conflict�s scope.</p><p>Flexner, Abraham (b. Nov. 13, 1866, Louisville, Ky., U.S.�d. Sept.  21, 1959, Falls Church, Va.) U.S. educator. He taught high school for  almost 20 years. When the Carnegie Foundation asked him to evaluate</p><p>the 155 U.S. and Canadian medical colleges, his report (1910) had a sen�  sational impact; many of the colleges he severely criticized closed, and  others revised their policies and curricula. Flexner thereafter channeled  over half a billion dollars from the Rockefeller Foundation into improv�  ing U.S. medical education. In 1930 he founded the Institute for Advanced  Study in Princeton, N.J., to which he brought some of the world�s out�  standing scientists.</p><p>Flick, Friedrich (b. July 10, 1883, Ernsdorf, near Bonn, Ger.�d. July  20, 1972, near Lake Constance, Switzerland) German industrialist. Before  World War II he built an industrial empire that included iron-ore and coal  mines, steel mills, trucks, airplanes, and munitions. He became Adolf Hit�  ler�s biggest industrial supplier, and at the NOrnberg trials he was con�  victed of using slave labour in his mines and plants. Though much of his  empire was confiscated, he later amassed another fortune in coal and steel,  and at the time of his death was probably West Germany�s wealthiest man.</p><p>flicker Any of six species of New World woodpeckers (genus Colaptes )  noted for spending much time on the  ground eating ants. The sticky saliva  of the flicker is alkaline, perhaps to  counteract the formic acid that ants  secrete. Its bill is more slender than  that of most woodpeckers and is  slightly down-curved. Most flickers  have a white rump, black breast  band, and varied head markings, and  most are about 13 in. (33 cm) long.</p><p>flight recorder Instrument that  records the performance and condi�  tion of an aircraft in flight. Regulatory  agencies require these devices on  commercial aircraft to make possible  the analysis of crashes or other  unusual occurrences. They are  housed in heavy steel within layers of  insulation, protecting them against  impacts and fires. The recording tape  is also protected against inadvertent  erasure and contact with seawater. It  records airspeed, altitude, heading,  vertical acceleration, and aircraft  pitch. It also includes a separate  device that records voice communi�  cation within the aircraft and by  radio. Both recorders are carried in the tail of the aircraft.</p><p>Flinders, Matthew (b. March 16, 1774, Donington, Lincolnshire,  Eng.�d. July 19, 1814, London) British mariner and hydrographer. In  two expeditions (1795-99, 1801-03) he circumnavigated Australia and  Tasmania, charting their coasts and waters. His Voyage to Terra Australis  (1814) recounted his adventures. His name was given to several geo�  graphic entities in Australia. Funders Petrie was his grandson.</p><p>Flinders Ranges Mountain region north of Adelaide, South Australia.  Continuing the Mount Lofty Ranges from Gulf St. Vincent, it extends  some 500 mi (800 km) to the northeast. The Flinders exceed 3,000 ft (900  m) at several points, reaching 3,842 ft (1,171 m) at St. Mary Peak, the  state�s second highest peak. The ranges feature scenic landscapes and  include Flinders Ranges National Park and Gammon Ranges National  Park.</p><p>Flinders River River, Queensland, Australia. It rises on the southwest�  ern slopes of the Gregory Range and flows west and then north to the  Gulf of Carpentaria through two mouths, the second known as the Bynoe  River, after a course of 520 mi (837 km). The river�s valley was first  settled in 1864; its lands are used in part for raising cattle and sheep. Only  its lowest 70 mi (113 km) are usually perennial, with the rest of the river  drying up during certain seasons of the year.</p><p>flint See CHERT AND FLINT</p><p>Flint City (pop., 2000: 124,943), eastern Michigan, U.S. Originally the  site of a trading post, the city was laid out in 1836 and became a fur�  trading and agricultural centre.

By the 1950s, the city was second only to Detroit in U.S. automo�  bile manufacturing. The closing of various GM plants in the 1980s and  �90s left Flint with a shrinking economy. The GMI Engineering and Man�  agement Institute (1919) and the University of Michigan-Flint (1956) are  located there.</p><p>flintlock Ignition system for firearms developed in the early 16th cen�  tury. It superseded the matchlock and the wheel lock and remained in use  until the mid-19th century. The most successful version, the true flintlock,  was invented in France in the 17th century. When the trigger was pulled,  a spring action caused the frizzen (striker) to strike the flint, showering  sparks onto the gunpowder in the priming pan; the ignited powder, in turn,  fired the main charge in the bore, propelling the ball.</p><p>Flodden, Battle of (Sept. 9, 1513) English victory over the Scots,  fought in Flodden Field, near Branxton, Northumberland, Eng. To honour  his alliance with France and divert troops from the main English army,  then in France under Henry VIII, James IV of Scotland crossed the English  border on August 22 with an army of about 30,000 men supported by  artillery. Henry�s lieutenant, the future 3rd duke of Norfolk, gathered an  army of 20,000 and issued a challenge to James, who agreed to fight on  September 9. By nightfall the Scottish army had been annihilated and  James was dead, together with more than 10,000 of his subjects.</p><p>flood High-water stage in which water overflows its natural or artificial  banks onto normally dry land, such as a river inundating its floodplain.  Uncontrollable floods likely to cause considerable damage commonly  result from excessive rainfall in a brief period, but they may also result  from ice jams during the spring rise in rivers, and from tsunamis. Com�  mon measures of flood control include improving channels, constructing  protective levees and storage reservoirs, and implementing programs of  soil and forest conservation to retard and absorb runoff from storms.</p><p>floor Rigid building assembly that divides space horizontally into sto�  ries. It forms the bottom of a room. It may consist of joist-supported wood  planks or panels, decking or panels supported by wood or steel beams, a  slab of stone or concrete on the ground, or a reinforced-concrete slab car�  ried by concrete beams and columns. The floor assembly must support its  own dead load plus the live load of occupants, activities, and furnishings.  The horizontal supports beneath its top surface�and the vertical supports  into which they frame�must be sufficiently large and spaced closely  enough to prevent sagging of the assembly.</p><p>floor covering Finish material on floors, including wood strips, par�  quet, linoleum, vinyl, asphalt tile, rubber, cork, epoxy resins, ceramic tile,  and carpeting. Wood-strip flooring, attached to a subfloor of plywood, is  most popular, especially for residences. Vinyl tiles and sheets have dis�  placed linoleum in most residential and commercial work. Nonslip rubber  and cork are used for commercial and industrial applications. Terrazzo  provides a hard, durable surface for public spaces. The Greeks used pebble  mosaics as early as the 8th century bc. Tessellated pavement (mosaics of  regularly shaped cubes) appeared in the Hellenistic Age and by the 1st  century ad had come into popular use in and around buildings through�  out the Roman empire. Inlaid stone, popular in Byzantine, Renaissance,  and Gothic architecture, is now only occasionally applied in lobbies and  entrance ways of grand spaces.</p><p>floor exercise Event in gymnastics competition consisting of various  ballet and tumbling movements (including jumps, somersaults, and hand�  stands) performed without apparatus. Women�s routines are performed  with musical accompaniment, men�s routines without it. The whole rou�  tine must be performed with rhythm and harmony and must be designed  to use a major portion of an area 12 m (39 ft 4 in.) square. It was included  as an Olympic medal event for men in 1936 and for women in 1952.</p><p>floppy disk or diskette Magnetic storage medium used with com�  puters. Floppy disks are made of flexible plastic coated with a magnetic  material, and are enclosed in a hard plastic case. They are typically 3.5  in. (9 cm) in diameter. Data are arranged on their surfaces in concentric  tracks. A disk is inserted in the computer�s floppy disk drive, an assem�  bly of magnetic heads and a mechanical device for rotating the disk for  reading or writing purposes. A small electromagnet, called a magnetic  head, writes a binary digit (1 or 0) onto the disk by magnetizing a tiny  spot on the disk in different directions, and reads digits by detecting the  magnetization direction of the spots. With the increasing use of e-mail  attachments and other means to transfer files from computer to computer,</p><p>the use of floppy disks has waned, though they are still widely used to  keep second (backup) copies of valuable files.</p><p>Flora Roman goddess of flowering plants. Her cult was supposedly intro�  duced into Rome during its earliest years by the Sabine king Titus Tatius.  Her temple stood near Rome�s Circus Maximus, and her festival, the Flo-  ralia, was instituted in 238 bc.</p><p>flora All species of plants that are found in a particular region, period,  or special environment. Six floral kingdoms are commonly distinguished:  Boreal (Holarctic), Paleotropical, Neotropical, South African (Capensic),  Australian, and Antarctic. These kingdoms are further broken down into  subkingdoms and regions, over which there is some dispute.</p><p>floral decoration Art of arranging living or dried plant material for  adornment of the body or home, for public and religious ceremonies, or  for festivals. Line, form, colour, texture, balance, porportion, and scale  are important aspects of floral arrangement, as is the container. The ear�  liest pictorial example is a 2nd-century Roman mosaic from the villa of  Hadrian at Tivoli depicting a basket of cut flowers. Dutch and French  still-life paintings of the 17th�18th centuries show the popularity of flo�  ral arrangements. Their long history in China and Japan is often associ�  ated with religious and philosophical beliefs; Japanese forms have become  influential in the West. See also ikebana.</p><p>Florence Italian Firenze \fe-'rent-sa\ City (pop., 2001 prelim.:  352,227), capital of Tuscany, central Italy. Built on both sides of the Arno  River, the city has been during its long history a republic, a seat of the  duchy of Tuscany, and a capital (1865-71) of Italy. Founded as a Roman  military colony in the 1st century bc, it was controlled in turn by the Goths,  Byzantines, and Lombards. A leading city of Tuscany by the late 12th  century, it was ruled after 1434 by the powerful Medici family. It became  a republic under religious reformer Girolamo Savonarola, after whose  downfall the Medici were restored as dukes of Florence (1531). Florence�s  vernacular became the Italian language, and from the 14th to the 16th  century Florence was among the greatest cities of Europe, preeminent in  commerce, finance, learning, and the arts. Many notables flourished there,  including Leonardo da Vinci, Michelangelo, Filippo Brunelleschi, Dante, Nic-  colo Machiavelli, and Galileo. The buildings, including the Baptistery of  St. John, the Gothic Duomo, and the Uffizi Gallery, are works of art them�  selves abounding in yet more works of art. Among the palaces and parks  are the Pitti Palace and its Boboli Gardens. The university was founded  in 1321. The economy is based primarily on tourism, though it also has  developed newer sectors such as information technology and high-fashion  clothing. The region around the city has a modern and dynamic economy  based on small industrial production and quality exports.</p><p>Florentine canvas work See bargello</p><p>Florey, Howard Walter, Baron (b.

Educated in Britain and the U.S., Florey taught at the Uni�  versity of Oxford from 1935. Investigating tissue inflammation and secre�  tion of mucous membranes, he succeeded in purifying lysozyme, a  bacteria-destroying enzyme found in tears and saliva, and characterized  the substances it acted on. He surveyed other naturally occurring anti�  bacterial substances, concentrating on penicillin, which he, with Ernst Boris  Chain, isolated and purified for general clinical use. The two demonstrated  penicillin�s curative properties in human studies and developed methods  for producing it in quantity. In 1945 he shared a Nobel Prize with Chain  and Alexander Fleming, and in 1965 he was created a life peer.</p><p>floriculture Branch of ornamental horticulture concerned with growing  and marketing flowers and ornamental plants, as well as with flower  arrangement. Because flowers and potted plants are largely produced in  plant-growing structures in temperate climates, floriculture is largely  thought of as a greenhouse industry; however, many flowers are cultivated  outdoors. Both the production of bedding plants and the production of cut�  tings to be grown in greenhouses or for indoor use (foliage plants) are  usually considered part of floriculture.

It covers 58,599 sq mi (151,771 sq km); its capital is Talla�  hassee. Indian groups entered Florida from the north as early as 10,000  years ago. It was explored by Juan Ponce de Leon c. 1513, and in 1565  Spaniards founded St. Augustine. Florida became a British possession in</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>684 I Florida &#x25BA; flower</p><p>1763 after the French and Indian War. The area reverted to Spanish con�  trol after the American Revolution (1783) but was used by the British as a  base of operations during the War of 1812. Andrew Jackson�s capture of  Pensacola during the First Seminole War (see Seminole Wars) led to the  cession of Florida to the U.S. in 1819. Florida became a state in 1845. It  seceded from the Union in 1861, then was readmitted in 1868. In the late  20th century it became one of the fastest growing states in the U.S. It  produces about 75% of the nation�s citrus fruits and is second only to  California in vegetable production. Tourism is a leading industry, with  Disney World a major attraction. Electronics manufacture is important, and  the aerospace industry, led by the Kennedy Space Center (see Cape  Canaveral), employs many thousands of people. The state, and especially  the city of Miami with its large Cuban population, plays a major economic  role in the Caribbean region. Among its many recreational areas is Ever�  glades National Park.</p><p>Florida, Straits of Passage connecting the Gulf of Mexico with the  Atlantic Ocean. Extending for about 110 mi (180 km) between the Florida  Keys on the north and Cuba and the Bahamas on the south, the straits  mark the area where the Florida Current, the initial part of the Gulf Stream,  flows east out of the Gulf of Mexico. The Spanish explorer Juan Ponce de  Leon first recorded sailing through the straits in 1513.</p><p>Florida Controversy, West See West Florida Controversy</p><p>flotation or froth flotation Most widely used process for extracting  many minerals from their ores. The method separates and concentrates ores  by altering their surfaces so that they are either repelled or attracted by  water. Unwetted particles, which adhere to air that is bubbled through the  water, will float in the froth, while wetted particles will sink. The process  was developed on a commercial scale early in the 20th century to remove  very fine mineral particles that formerly had gone to waste in gravity con�  centration plants. With its use to concentrate copper, lead, and zinc min�  erals, which commonly accompany one another in their ores, many  complex ore mixtures formerly of little value have become major sources  of certain metals.</p><p>flounder Any of about 300 species of flatfishcs (order Pleuronecti-  formes). When born, the flounder is  bilaterally symmetrical, with an eye  on each side, and it swims near the  sea�s surface. After a few days, it  begins to lean to one side, and the  eye on that side migrates to what  eventually becomes the top side.</p><p>With this development comes  changes in bones, nerves, and  muscles, and the underside loses its  colour. As an adult, the flounder lives  on the sea bottom with the eyed side  on top.</p><p>flour Finely ground cereal grain or other starchy portions of plants. Flour,  especially wheat flour, is a basic ingredient of baked goods (see baking).  In the production of refined flour, the starchy endosperm is separated from  the other parts of the kernel by milling through rollers. In the production  of whole-wheat flour, all parts of the kernel are used. Following milling,  the particles of endosperm (called semolina) are ground to flour and often  bleached to imitate natural aging. Flour grades are based on the residual  amount of branny particles. When flour is mixed with water to make  dough, its protein content is converted to gluten, an elastic substance that  forms a continuous network throughout the dough and is capable of retain�  ing gas, thus causing the baked product to expand, or rise.</p><p>flow See DEFORMATION AND FLOW, LAMINAR flow, TURBULENT FLOW</p><p>flow meter Device that measures the velocity of a gas or liquid. It has  applications in medicine as well as in chemical engineering, aeronautics,  and meteorology. Examples include pitot tubes, venturi tubes, and rotame�  ters (tapered graduated tubes with a float inside that is supported by the  flowing fluid at a level that depends on the flow rate). Ultrasonic flow  meters, in which reflecting ultrasound off a flowing liquid leads to a Dop�  pler shift (see Doppler effect) that is calibrated to provide the flow rate of  the liquid, have important industrial applications and have also been used  to measure arterial blood flow.</p><p>flowchart Graphical representation of a process, such as a manufac�  turing operation or a computer operation, indicating the various steps</p><p>taken as the product moves along the production line or the problem  moves through the computer. Individual operations can be represented by  closed boxes, with arrows between boxes indicating the order in which  the steps are taken and divergent paths determined by variable results.</p><p>flower Reproductive portion of any flowering plant (angiosperm). Popu�  larly, the term applies especially when part or all of the reproductive  structure is distinctive in colour and form. Flowers present a multitude of  combinations of colour, size, form, and anatomical arrangement. In some  plants, individual flowers are very small and are borne in a distinctive  cluster (inflorescence). Each flower consists of a floral axis that bears the  essential organs of reproduction (stamens and pistils) and usually acces�  sory organs (sepals and petals); the latter may serve both to attract pol�  linating insects (see pollination) and to protect the essential organs. Flower  parts are arrayed usually in whorls, but sometimes spirally. Four distinct  whorls are common: the outer calyx (sepals), the corolla (petals), the  androecium (stamens), and, in the centre, the gynoecium (pistils). The  sepals are usually greenish and often resemble reduced leaves; the petals  are usually colourful and showy. Pollen is produced in the stamens. A  pollen-receptive stigma rests atop each pistil. The pistil, made up of one  or more carpels, encloses an ovary that contains the ovules, or potential  seeds. After fertilization, the ovary enlarges to form the fruit. Flowers have  been symbols of beauty in most civilizations of the world, and flower giv�  ing is still among the most popular of social amenities.</p><p>sac mK ' 1</p><p>0 O �</p><p>The life cycle of a flowering plant. (1) A pollen grain is released from the anther  and settles on the stigma. (2) A pollen tube forms and grows through the style  toward the ovule opening (micropyle). (3) Two of the nuclei (polar nuclei) in the  ovule's embryo sac migrate to the centre to form a single cell. Three cells migrate to  the micropyle, and one enlarges to become the egg. Two sperm that have formed  from mitotic division of the pollen grain's generative cell enter the embryo sac  through the micropyle. (4) One sperm fuses with the egg, resulting in a fertilized  egg (zygote), which develops into an embryo. The second sperm fuses with the two  polar nuclei to form the endosperm nucleus. (5) This nucleus divides to form a tissue  (endosperm) that provides nutrients for the developing embryo.</p><p>� MERRIAM-WEBSTER INC.</p><p>Flounder ( Platichthys )</p><p>F.

They are often differentiated from  gymnosperms by their production of seeds within a closed chamber (the  ovary) within the flower, but this distinction is not always clear-cut. The  division is composed of two classes: monocots and dicots (see cotyledon).  Monocots have flower parts in threes, scattered conducting strands in the  stem, and usually prominent parallel veins in the leaves, and they lack a  cambium. Dicots have flower parts in fours or fives, conducting strands  arranged in a cylinder, a net-veined pattern in the leaves, and a cambium.  Flowering plants reflect an immense diversity in habit, size, and form;  they account for more than 300 families growing on every continent,  including Antarctica. Flowering plants have adapted to almost every habi�  tat. Most reproduce sexually by seeds via the specialized reproductive  organs that are present in all flowers.</p><p>flu See INFLUENZA</p><p>fliigelhorn Brass musical instrument, a valved bugle. It has three valves  and a wider bore than the cornet and is usually pitched in B-flat. The  fliigelhorn was invented in Austria in the 1830s. It has maintained its  identity�particularly its bore and its squat shape�better than has the  formerly very similar cornet. Long used in European military bands, it is  now also used in jazz and popular music.</p><p>fluid Any liquid or gas that cannot sustain a shearing force when at rest  and that undergoes a continuous change in shape (see flow) when sub�  jected to such a stress. Compressed fluids exert an outward pressure that  is perpendicular to the walls of their containers. A perfect fluid lacks vis�  cosity, but real fluids do not.</p><p>fluid mechanics Study of the effects of forces and energy on liquids  and gases. One branch of the field, hydrostatics, deals with fluids at rest;  the other, fluid dynamics, deals with fluids in motion and with the motion  of bodies through fluids. Liquids and gases are both treated as fluids  because they often have the same equations of motion and exhibit the  same flow phenomena. The subject has numerous applications in fields  varying from aeronautics and marine engineering to the study of blood  flow and the dynamics of swimming.</p><p>fluke or trematode Any member of almost 6,000 species of parasitic  flatworms. Flukes are found world�  wide and range in size from about  0.2 to 4 in. (5-100 mm) long. They  most commonly parasitize fish,  frogs, and turtles, but also humans,  domestic animals, and invertebrates  such as mollusks and crustaceans.</p><p>They include external parasites  (ectoparasites), internal parasites  (endoparasites), and semi-external  parasites (those that attach to the lin�  ing of the mouth, to gills, or to the cloaca). Most flukes are flattened and  leaflike or ribbonlike and have muscular suckers on the bottom surface,  as well as hooks and spines, for attachment to the host. Fluke infestations  may cause illness (e.g., schistosomiasis) or death in humans.</p><p>fluorescence Emission of electromagnetic radiation, usually visible  light, caused by excitation of atoms in a material, which then reemit almost  immediately (within about 10 -8 seconds). The initial excitation is usually  caused by absorption of energy from incident radiation or particles, such as  X-rays or electrons. Because reemission occurs so quickly, the fluores�  cence ceases as soon as the exciting source is removed, unlike phosphores�  cence, which persists as an afterglow. A fluorescent lightbulb is coated on  the inside with a powder and contains a gas; electricity causes the gas to  emit ultraviolet radiation, which then stimulates the tube coating to emit  light. The pixels of a television or computer screen fluoresce when elec�  trons from an electron gun strike them. Fluorescence is often used to ana�  lyze molecules, and the addition of a fluorescing agent with emissions in  the blue region of the spectrum to detergents causes fabrics to appear whiter  in sunlight. X-ray fluorescence is used to analyze minerals.</p><p>fluorescent lamp Type of electric discharge lamp consisting of a glass  tube filled with a mixture of argon and mercury vapor. A current of elec�  tricity causes the vapor to produce ultraviolet radiation that, in turn,  excites a phosphor coating on the inside of the tube, causing it to fluo�  resce, or reradiate the energy as visible light. Fluorescent lamps are cooler</p><p>and more efficient than incandescent lamps. They are commonly installed  with diffusers as part of a suspended ceiling system. See also fluorescence.</p><p>fluoridation of water Addition of fluoride compounds to water (see  fluorine) at one part per million to reduce dental caries (cavities). This  practice is based on the lower rates of caries seen in areas with moderate  natural fluoridation of water and on studies showing that sound teeth con�  tain more fluoride than cavity-prone teeth and that fluorides help prevent  or reduce dental caries. Fluoridation decreases the number of decayed,  missing, and filled teeth in children (which increases if fluoridation is  stopped), but it has provoked controversy in some cases. Excess fluoride  may cause tooth mottling (a problem of appearance only) and, in higher  doses, bone abnormalities. Fluoridation also helps prevent rickets in  infants and children and helps the thyroid maintain a normal basal meta�  bolic rate.</p><p>fluorine Vflur-.en, 'fl6r-,en\ Nonmetallic chemical element, chemical  symbol F, atomic number 9. The lightest halogen, it is the most reactive  element, forming compounds with all others except helium, neon, and  argon (the lighter noble GASes). Its only valence is 1, in F 2 (the diatomic  molecule) and fluorides. A toxic, pale yellow gas with a pungent odour,  it can be produced only by electrolysis under special conditions. Its chief  source is fluorite; it also occurs in cryolite, fluorapatite, seawater, bones,  and teeth. Hydrogen fluoride (HF) is a raw material for many other fluo�  rides. Its water solution, hydrofluoric acid, is used to clean metals and to  polish, etch, or frost glass. Other fluorides are useful catalysts and raw  materials. Sodium fluoride (NaF) is added to water and tin fluoride (SnF 2 )  to dental-care products to reduce dental caries (see fluoridation of water).  Fluorocarbons are hydrocarbons in which some hydrogen atoms have  been replaced by fluorine atoms; examples include Freons and Teflon.</p><p>fluorite or fluorspar Common halide mineral, calcium fluoride (CaF 2 );  the principal fluorine mineral. Fluorite occurs most commonly as a vein  mineral and is often associated with lead and silver ores; it also occurs in  cavities, sedimentary rocks, pegmatites, and hot-springs areas. It is wide�  spread in China, South Africa, Mongolia, France, Mexico, Russia, and  the central U.S. Fluorite is used in the manufacture of steel, aluminum  fluoride, artificial cryolite, and aluminum. It is used in glassmaking, in  iron and steel enamelware, in the production of hydrofluoric acid, in the  refining of lead and antimony, and (as a catalyst) in the manufacture of  high-octane fuels.</p><p>Flushing Northern section, Queens, New York, New York, U.S. Located  at the head of Flushing Bay in the East River, it was settled in 1645 by  English nonconformists and became a centre for Quakers (see Society of  Friends). In the late 18th and early 19th centuries, it flourished as a township  and then a village until it was absorbed by Queens in 1898. Flushing  Meadow-Corona Park was the site of the 1939-40 and 1964-65 New York  world�s fairs (the Hall of Science remains as an exhibition centre), and in  1946-49 it was the temporary headquarters for the UN. Flushing is the  scene of the U.S. Open tennis championships and home to Shea Stadium.</p><p>flute Woodwind instrument in which the sound is produced by blowing  against a sharp edge. In its broad sense, a flute may be end-blown, like  the recorder, or may have a globular shape, like the ocarina. In its nar�  row sense, discussed below, flute refers to the transverse flute of Western  music. The transverse flute, a tubular instrument held sideways to the  right, appeared in Greece and Etruria by the 2nd century bc. By the 16th  century a family of boxwood flutes, with fingerholes but no keys, was in  use in Europe. Keys began to be added in the late 17th century. Theobald  Boehm�s 19th-century innovations resulted in the modern flute, which per�  mits thorough expressive control and great agility. The cylindrical tube  may be made of wood or, more often, a precious metal or alloy. Its range  is from about middle C to the C three octaves higher. The flute family  includes the piccolo (pitched an octave higher), the alto flute, and the rare  bass flute.

Limestone is commonly used for this purpose in smelting iron ores.  Other materials used as fluxes are silica, dolomite, lime, borax, and fluo�  rite. In soldering, the flux removes oxide films, promotes wetting, and  prevents reoxidation of the surfaces during heating. Rosin is widely used  as a noncorrosive flux when electronic equipment is soldered; in other  applications, a water solution of zinc chloride and ammonium chloride  may be used.</p><p>Liver fluke (Fasciola hepatica)</p><p>GRANT HEILMAN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>686 I Fluxus &#x25BA; Foch</p><p>Fluxus \'fbk-s3s\ International avant-garde group of artists founded in  Germany by U.S. artist George Maciunas (1931-78) in 1962. Its mem�  bers, including Joseph Beuys, John Cage, and Yves Klein, explored media  ranging from performance art to poetry to experimental music. Opposed  to tradition and professionalism in the arts, the Fluxus group shifted the  emphasis from what an artist makes to the artist�s personality, actions,  and opinions. Throughout the 1960s and �70s they staged �action� events,  engaged in politics and public speaking, and produced sculptural works  featuring unconventional materials. Though it was an influential move�  ment in Europe, the group�s work frequently conflicted with authority and  aroused much controversy.</p><p>fly In general, almost any small flying insect. In entomology, the term  refers specifically to the approximately 85,000 species of two-winged, or  �true,� flies (dipterans). Other insects called flies have wing structures that  differ from that of dipterans.</p><p>Fly River River, New Guinea Island. One of the island�s largest rivers,  it flows almost wholly through Papua New Guinea. For a short stretch of  its middle course, it forms the border between Papua New Guinea and  Indonesia. Rising in the Victor Emanuel Range in the central highlands,  it flows south for about 700 mi (1,100 km) to the Coral Sea; much of it  is navigable.</p><p>flycatcher Any of numerous small passerine birds that capture insects  on the wing, particularly more than 100 Old World species of the family  Muscicapidae and more than 400 New World species called tyrant fly�  catchers (family Tyrannidae). The most common Old World species, the  spotted flycatcher (Muscicapa striata), is 5.5 in. (14 cm) long and streaked  grayish brown. It inhabits open woodlands and gardens eastward from  Europe, where it breeds, through Asia. Tyrant flycatchers include the  manakins, pewees, kingbirds, becards, and cotingas, among others. Most  have a large head, short legs, and a broad bill (e.g., phoebes).</p><p>flying buttress Masonry structure typically consisting of an inclined  bar carried on a half arch that extends (�flies�) from the upper part of a  wall to a pier some distance away and carries the thrust of a roof or vault.  A pinnacle (vertical ornament of pyramidal or conical shape) often crowns  the pier, adding weight and enhancing stability. The flying buttress  evolved in the Gothic era from earlier simpler, hidden supports. The  design increased the supporting power of the buttress and allowed for the  creation of the high-ceilinged churches typical of Gothic architecture.</p><p>flying fish Any of about 40 species of oceanic fishes (family Exoco-  etidae). They are found worldwide in warm waters and are noted for their  ability to �fly.� All species are less than 18 in. (45 cm) long and have  winglike, rigid fins and an unevenly forked tail. Two-winged species have  only the pectoral fins enlarged; four-winged species have both the pec�  toral and the pelvic fins enlarged. Rather than flying, they actually glide  after jumping from the water. They can make several consecutive glides;  the strongest fliers can travel as much as 600 ft (180 m) in a single glide,  and compound glides may cover 1,300 ft (400 m). The behaviour is pri�  marily a means of escaping predators.</p><p>Flying Fortress See B-17</p><p>flying shuttle Machine that represented an important step toward auto�  matic weaving. It was invented by John Kay in 1733. In previous looms,  the shuttle was thrown, or passed, through the threads by hand, and wide  fabrics required two weavers seated side by side passing the shuttle  between them. Kay mounted his shuttle on wheels in a track and used  paddles to shoot the shuttle from side to side when the weaver jerked a  cord. Using the flying shuttle, one weaver could weave fabrics of any  width more quickly than two could before.</p><p>flying squirrel Any member of two distinct groups of rodents that are  able to make gliding leaps by means of parachute-like membranes con�  necting their forelegs and hind legs on each side. North American and  Eurasian flying squirrels, in the squirrel family (Sciuridae), are slender,  long-limbed forest dwellers with soft fur and large eyes. They are 3-24  in. (8-60 cm) long, excluding the often-flattened tail, and feed on nuts,  fruit, other plant material, and insects. They seldom descend to the ground.  They can glide 200 ft (about 60 m) or more from one tree to another. The  scaly-tailed flying squirrels of Africa (family Anomaluridae) have rows of  scales on the underside of their tufted tail that help them climb and cling  to trees. They are similar in appearance and feeding preferences to the  sciurids and are about 4-16 in. (10�40 cm) long without the tail.</p><p>Flying Tigers or American Volunteer Group Group of U.S.  civilian volunteer pilots recruited by Col. Claire Chennault to fight the  Japanese in Burma (Myanmar) and China in 1941-42. Surprise, mobil�  ity, precision flying, and unorthodox tactics enabled the Tigers to outwit  the Japanese and inflict considerable damage on their air and ground  forces.</p><p>Flynn, Errol (Leslie Thomson) (b. June 20, 1909, Hobart, Tas.,  Austl.�d. Oct. 14, 1959, Vancouver, B.C., Can.) Australian-U.S. film  actor. He sought adventure in New Guinea before turning to acting in  Australia and England. In 1935 Warner Brothers brought him to Holly�  wood, and he became an instant success as the swashbuckling hero of  Captain Blood. He continued to play dashing heroes through the 1940s  in films such as The Charge of the Light Brigade (1936), The Adventures  of Robin Hood (1938), The Sea Hawk (1940), They Died with Their Boots  On (1941), and Gentleman Jim (1942). After a period marred by scandal  and bad roles, he returned to critical and popular praise in The Sun Also  Rises (1957).</p></section><section><p>flysch Vflish\ Sequence of shales interbedded with thin, hard, graywacke-  like sandstones. Such sequences are usually thousands of yards thick, but  the individual beds are only a few inches to a few yards thick. The occa�  sional presence of fossils indicates marine deposition. The term originally  was applied to a formation of the Tertiary Period in the northern Alpine  region, but it now denotes similar deposits of other ages and places.</p><p>flytrap See Venus's-flytrap</p><p>flywheel Heavy wheel attached to a rotating shaft to smooth out deliv�  ery of power from a motor to a machine. The inertia of the flywheel  opposes and moderates fluctuations in the speed of the engine and stores  the excess energy for intermittent use. In automobile engines, the flywheel  smooths out the pulses of energy provided by the combustion in the cyl�  inders and provides energy for the compression stroke of the pistons. In  power presses the actual punching, shearing, and forming are done in only  a fraction of the operating cycle. During the longer, nonactive period, the  speed of the flywheel is built up slowly by a comparatively low-powered  motor. When the press is operating, most of the required energy is pro�  vided by the flywheel.</p><p>FM in full frequency modulation Variation of the frequency of a  carrier wave (commonly a radio wave) in accordance with variations in  the audio signal being sent. Developed by American electrical engineer  Edwin H. Armstrong in the early 1930s, FM is less susceptible to outside  interference and noise (e.g., thunderstorms, nearby machinery) than is  AM. Such noise generally affects the amplitude of a radio wave but not  its frequency, so an FM signal remains virtually unchanged. FM is also  better able to transmit sounds in stereo than AM. Commercial FM broad�  casting stations transmit their signals in the frequency range of 88 mega�  hertz (MHz) to 108 MHz.</p><p>Fo, Dario (b. March 24, 1926, Leggiuno-Sangiano, Italy) Italian play�  wright. He and his wife, Franca Rame, founded a theatre company that  developed a leftist theatre of politics and later established an acting troupe  with funding from the Italian Communist Party. In 1970 they set up a  touring collective to perform in factories and other public sites. Fo�s  popular one-man show Mistero Buffo (1973) was censured by the Vatican.  He wrote more than 70 plays, including the satire Accidental Death of an  Anarchist (1974) and The Pope and the Witch (1989). He was awarded  the Nobel Prize in 1997.</p><p>Foch Vfosh,\ English VfashV Ferdinand (b. Oct. 2, 1851, Tarbes,  France�d. March 20, 1929, Paris) French commander of Allied forces  in World War I. He entered the artillery corps in 1873 and from 1885  periodically taught military strategy at the war college, becoming its com�  mandant in 1908. After World War I broke out, he commanded an army  detachment and planned the strategy that enabled Joseph-Jacques-Cesaire  Joffre to win the First Battle of the Marne. After commanding at the  Battles of Ypres and the Somme, Foch was appointed chief of the general  staff (1917), adviser to the Allied armies, and then commander in chief  of all Allied armies (May 1918), in which capacity he prevailed on the  battlefield against Erich Ludendorff. When Germany was forced to ask for  an armistice, the conditions were dictated by the recently promoted Mar�  shal Foch. Considered the leader most responsible for the Allied victory,  he was showered with honours after the war and was buried near Napo�  leon in the Invalides.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Focke-Wulf 190 &#x25BA; folk music I 687</p><p>Focke-Wulf 190 (Fw 190) Vfo-ko-'vulfX Fighter aircraf of Nazi Ger�  many, second in importance only to the Messerschmitt 109 in the German  air force in World War II. It began service in 1941, was superior to all its  opponents until 1942�43, and remained a successful fighter and fighter-  bomber until the war ended. A single-seater, it was armed with four 7.9-mm  machine guns; later versions also carried cannons. The model produced  near the end of the war had a top speed of about 430 mph (690 kph).</p><p>fog Cloud of small water droplets near ground level that is dense enough  to reduce horizontal visibility to less than about 3,000 ft (1,000 m). Fog  may also refer to clouds of smoke particles (smog), ice particles, or mix�  tures of these components. When visibility is more than 3,000 ft, the phe�  nomenon is termed mist or haze, depending on whether it is caused by  water drops or by solid particles. Fog is formed by the condensation of  water vapour on condensation nuclei that are always present in natural  air. The most stable fogs occur when the surface is colder than the air  above. Fogs can also occur when cold air moves over a warm, wet sur�  face and becomes saturated by the evaporation of moisture from the sur�  face. Convection currents carry the fog upward as it forms, and it appears  to rise as steam or smoke from the wet surface.</p><p>Foix \'fwa\ Historical region, southern France. It corresponds approxi�  mately to the modern departement of Ariege in the region of Midi-  Pyrenees. Foix was a quasi-independent power from the 11th to the 15th  century. Bounded by Languedoc and by the territories of the counts of  Roussillon and the kings of Aragon, it became part of the crown lands at  the ascension of Henry IV as king of France (1589).</p><p>Fokine \fo-'ken\, Michel orig. Mikhail Mikhaylovich Fokine</p><p>(b. April 23, 1880, St. Petersburg,</p><p>Russia�d. Aug. 22, 1942, New  York, N.Y., U.S.) Russian-born U.S.  dancer and choreographer. He  trained at the Imperial Ballet School  in St. Petersburg and debuted at the  Mariinsky Theatre at age 18. Follow�  ing his creation of The Dying Swan  for Anna Pavlova in 1905, he was in  demand as a choreographer. When  his ambitious scenario for a ballet on  the story of Daphnis and Chloe was  rejected, Sergey Diaghilev in 1909  engaged Fokine at the Ballets Russes  in Paris, where he choreographed  works such as The Firebird (1910),</p><p>Petrushka (1911), and Daphnis and  Chloe (1912). In these ballets he  strove for a greater dramatic and sty�  listic unity than had been previously  known. He moved to New York City  in 1923 and thereafter choreo�  graphed works for companies in the  U.S. and Europe.</p><p>Fokker, Anthony orig. Anton  April 6, 1890, Kediri, Java, Nether�  lands East Indies�d. Dec. 23, 1939,</p><p>New York, N.Y., U.S.) Dutch-U.S.  aircraft designer and manufacturer.</p><p>He built his first plane in 1910 and  taught himself to fly. In 1912 he  established a small aircraft factory  near Berlin. In World War I he pro�  duced over 40 types of airplanes for  Germany, having originally offered  his designs to both sides. He also  developed a gear system that  allowed a machine gun to fire  through a spinning propeller�s field.</p><p>In 1922 he moved to the U.S. and  opened an aircraft factory, where he  produced numerous commercial air�  craft that were used in the newly  developing U.S. airlines business.</p><p>folate See folic acid</p><p>fold In geology, an undulation or wave in the stratified rocks of the  Earth�s crust. Stratified rocks were originally formed from sediments that  were deposited in flat, horizontal sheets, although in some places the strata  are no longer horizontal but have warped. The warping may be so gentle  that the inclination of the strata is barely perceptible, or it may be so pro�  nounced that the strata of the two flanks are essentially parallel or nearly  flat. Folds vary widely in size; the tops of large folds are commonly eroded  away on the Earth�s surface.</p><p>foliation Planar arrangement of structural or textural features in any  rock type, but particularly that resulting from the alignment of constitu�  ent mineral grains of a metamorphic rock along straight or wavy planes.  Foliation commonly occurs parallel to original bedding, but it may not be  obviously related to any other structural direction. Foliation is exhibited  most prominently by sheety minerals, such as mica or chlorite.</p><p>folic acid \'fo-lik\ or folate Organic compound essential to animal  growth and health and needed by bacteria as a growth factor. Part of the  vitamin B complex, folic acid is necessary for synthesis of nucleic acids and  formation of the heme component of hemoglobin in red blood cells. To  prevent neural tube defects in babies, it should ideally be taken by women  starting at least a month before conception. Dietary folate sources include  leafy and dark green vegetables, citrus fruits, cereals, beans, poultry, and  egg yolks, but free folic acid is available only in supplements. Low intake  leads to folic acid deficiency anemia.</p><p>folic-acid-deficiency anemia Anemia resulting from too little folic  acid, needed for red-blood-cell maturation (see erythrocyte). White-cell  and platelet levels are also often low. Progressive gastrointestinal prob�  lems develop. It may result from poor diet or from malabsorption, cir�  rhosis of the liver, or anticonvulsant drugs; it may also occur in the last  three months of pregnancy and in severe hemolytic anemia (in which red  cells break down). The blood profile resembles that of pernicious anemia.  Taking folic acid causes rapid improvement; an adequate diet cures cases  caused by malnutrition.</p><p>Folies-Bergere \fo-Te-ber-'zher\ Music hall and variety theatre in Paris.  It opened in 1869 and soon became a major music hall, presenting oper�  ettas and pantomimes. By the 1890s its repertory also included vaudeville  sketches, acrobats, ballets, and magicians. After the vogue of nudity  appeared in Parisian music halls (1894), the Folies produced sensational  displays of women in scanty but opulent costumes that soon overshad�  owed its other performances. Under the management of Paul Derval  (1918-66), the Folies achieved an international reputation and became  one of Paris�s major tourist attractions. Each show requires about 10  months of preparation, 40 sets, and 1,000 costumes.</p><p>folk art Art produced in a traditional fashion by peasants, seamen,  country artisans, or tradespeople with no formal training, or by members  of a social or ethnic group that has preserved its traditional culture. It is  predominantly functional, typically produced by hand for use by the  maker or by a small group or community. Paintings are usually incorpo�  rated as decorative features on clock faces, chests, chairs, and interior and  exterior walls. Sculptural objects in wood, stone, and metal include toys,  spoons, candlesticks, and religious items. Folk architecture may include  public and residential buildings, such as eastern European wooden  churches and U.S. frontier log cabins. Other examples of visual folk arts  are woodcuts, scrimshaw, pottery, textiles, and traditional clothing.</p><p>folk dance Dance that has developed without a choreographer and that  reflects the traditional life of the common people of a country or region.  The term was coined in the 18th century and is sometimes used to dis�  tinguish between dances of the people and those of the aristocracy.  Courtly and formal dances of the 16th-20th centuries often developed  from folk dances; these include the gavotte, gigue, mazurka, minuet, polka,  samba, tango, and waltz. See also country dance; hula; morris dance; square  dance; sword dance; tap dance.</p><p>folk music Music held to be typical of a nation or ethnic group, known  to all segments of its society, and preserved usually by oral tradition.  Knowledge of the history and development of folk music is largely con�  jectural. Musical notation of folk songs and descriptions of folk music  culture are occasionally encountered in historical records, but these tend  to reflect primarily the literate classes� indifference or even hostility. As  Christianity expanded in medieval Europe, attempts were made to sup�  press folk music because of its association with heathen rites and cus�  toms, and uncultivated singing styles were denigrated. During the</p><p>Fokine as Perseus in Medusa</p><p>COURTESY OF THE DANCE COLLECTION, THE NEW YORK  PUBLIC LIBRARY AT LINCOLN CENTER, ASTOR, LENOX AND  T1LDEN FOUNDATIONS</p><p>Herman Gerard Fokker (b.</p><p>Anthony Fokker.</p><p>ULLSTEIN BILDERDIENST</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>688 i folk psychology &#x25BA; Fontainebleau</p><p>Renaissance, new humanistic attitudes encouraged acceptance of folk  music as a genre of rustic antique song, and composers made extensive  use of the music; folk tunes were often used as raw material for motets  and masses, and Protestant hymns borrowed from folk music. In the 17th  century folk music gradually receded from the consciousness of the lit�  erate classes, but in the late 18th century it again became important to art  music. In the 19th century, folk songs came to be considered a �national  treasure,� on a par with cultivated poetry and song. National and regional  collections were published, and the music became a means of promoting  nationalistic ideologies. Since the 1890s, folk music has been collected  and preserved by mechanical recordings. Publications and recordings  have promoted wide interest, making possible the revival of folk music  where traditional folk life and folklore are moribund. After World War II,  archives of field recordings were developed throughout the world. While  research has usually dealt with �authentic� (i.e., older) material not  heavily influenced by urban popular music and the mass media, the influ�  ence of singer-songwriters such as Woody Guthrie, Pete Seeger, Joan Baez,  and Bob Dylan expanded the genre to include original music that largely  retains the form and simplicity of traditional compositions.</p><p>folk psychology Ways of conceptualizing mind and the mental that  are implicit in our ordinary, everyday attributions of mental states to our�  selves and others. Philosophers have adopted different positions about the  extent to which folk psychology and its generalizations (e.g., those por�  traying human actions as governed by intention) are supported by the  findings of scientific psychology. Some consider it indispensible to under�  standing human conduct. Others (�eliminative materialists�) think that it  can and perhaps will be replaced by scientific psychology.</p><p>folklore Oral literature and popular tradition preserved among a people.  It may take the form of fairy tales, ballads, epics, proverbs, and riddles. Stud�  ies of folklore began in the early 19th century and first focused on rural  folk and others believed to be untouched by modern ways. Several aims  can be identified. One was to trace archaic customs and beliefs. In Ger�  many Jacob and Wilhelm Grimm published their classic collection of fairy  tales in 1812. James George Frazer�s The Golden Bough (1890) reflects the  use of folklore as a tool to reconstruct ancient beliefs and rituals. Another  motive for the study of folklore was nationalism, which reinforced eth�  nic identity and figured in struggles for political independence. The cata�  log of motifs of folktales and myths developed by Antti Aarne and Stith  Thompson encouraged comparisons of variants of the same tale or other  item from different regions and times. In the mid-20th century, new trends  emerged. Any group that expressed its inner cohesion by maintaining  shared traditions qualified as a �folk,� whether the linking factor be occu�  pation, language, place of residence, age, religion, or ethnic origin.  Emphasis also shifted from the past to the present, from the search for  origins to the investigation of present meaning and function. Change and  adaptation within tradition were no longer necessarily regarded as cor�  ruptive.</p><p>folly In architecture, an eccentric, generally nonfunctional (and often  deliberately unfinished) structure erected to enhance a romantic land�  scape. Follies were particularly in vogue in England in the 18th and early  19th century. They might resemble medieval towers, ruined castles over�  grown with vines, or crumbling Classical temples complete with fallen,  eroded columns. In the U.S., the term has been applied to ornate gazebos.  It may also be applied to any unusual building that is extravagant or  whimsical in style.</p><p>Folsom complex Prehistoric culture of North America on the eastern  side of the Rocky Mountains that is known from stone tools. It is char�  acterized by leaf-shaped flint projectile points having a concave base with  side projections and a longitudinal groove on each face. The complex was  first identified at Folsom, N.M., U.S. It includes a variety of scrapers,  knives, and blades and is generally dated to 8000-9000 bc. Like the ear�  lier Clovis complex, it is considered to be part of a Paleo-Indian big-game  hunting tradition.</p><p>Fon \'fan\ People of southern Benin and adjacent parts of Togo. They  speak a dialect of Gbe, a Kwa language of the Niger-Congo language  family. Numbering about 3 million, the Fon are mainly farmers. Craft  specialists include male ironworkers, sculptors, and weavers and female  potters. The primary Fon social unit is the polygynous family, each  woman and her children occupying a house within a compound. The vil�  lage under a hereditary chief is the traditional political unit. Dahomey  kingdom was peopled principally by Fon. See photo above.</p><p>Fonda, Henry (Jaynes) (b.</p><p>May 16, 1905, Grand Island, Neb.,  U.S.�d. Aug. 12, 1982, Los Ange�  les, Calif.) U.S. actor.

He portrayed thoughtful men  of integrity in films such as Young  Mr. Lincoln (1939), The Grapes of  Wrath (1940), and The Ox-Bow Inci�  dent (1943). He also made comedies  such as The Lady Eve (1941) and The  Male Animal (1942). He returned to  the stage in Mister Roberts (1948,  Tony Award; film, 1955). His last  film, On Golden Pond (1981, Acad�  emy Award), also starred his daugh�  ter Jane Fonda.

The  daughter of actor Henry Fonda, she  made her film debut in Tall Story  (1960), which began a career that  took dizzying turns. After playing  comic roles in such films as Cat Bal�  lou (1965) and Barefoot in the Park  (1967), she appeared as a sex kitten  in husband Roger Vadim�s (married  1965-73) futuristic Barbarella  (1968). She then plunged into leftist  political activity, marrying the activ�  ist Tom Hayden (married 1973-89)  and loudly condemning the Vietnam War, and made socially conscious  films including They Shoot Horses, Don�t They? (1969), Klute (1971,  Academy Award), and Coming Home (1978, Academy Award). She later  marketed a series of hugely popular exercise books and videotapes. After  marrying Ted Turner in 1991 (divorced 2001), she retired from the screen.</p><p>Fonseca \f6n-'sa-ko\, Gulf of Inlet of the Pacific Ocean, Central  America.

Beginning in the 1960s, it concentrated on developing high-yield  grain, eliminating protein deficiencies, supporting rural development, and  encouraging agricultural exports. In the 1980s and �90s, the FAO empha�  sized strategies for sustainable agriculture and rural development that  were economically feasible, environmentally sound, and technologically  appropriate to the skill level of the host country. The organization, which  has more than 180 members, is governed by the biennial FAO confer�  ence, in which each member country, as well as the European Union, is  represented. Its headquarters are in Rome. See also World Food Pro�  gramme.</p><p>Food and Drug Administration (FDA) Agency of the U.S. Depart�  ment of Health and Human Services. Established in 1927, it inspects, tests,  approves, and sets safety standards for foods and food additives, drugs,  chemicals, cosmetics, and household and medical devices. It can prevent  untested products from being sold and take legal action to halt the sale  of undoubtedly harmful products or of products that involve a health or  safety risk. Its authority is limited to interstate commerce; it cannot con�  trol prices nor directly regulate advertising except of prescription drugs  and medical devices.</p><p>food chain Sequence of transfer of matter and energy from organism  to organism in the form of food. These interconnected feeding relation�  ships intertwine locally into a food web because most organisms consume  or are consumed by more than one other type of organism. Plants and  other photosynthetic organisms (such as phytoplankton), which convert  solar energy to food, are the primary food source. In a predator chain, a  plant-eating animal is eaten by a larger animal. In a parasite chain (see  parasitism), a smaller organism consumes part of a larger host and may  itself be parasitized by even smaller organisms. In a saprophytic chain,  microorganisms live on dead organic matter. Because energy, in the form  of heat, is lost at each step, or trophic level, chains do not normally  encompass more than four or five trophic levels.</p><p>food poisoning Acute gastrointestinal illness from eating foods con�  taining toxins. These toxins may be poisons that occur naturally in plants  and animals, chemical contaminants, or toxic products of microorganisms.  Most cases are due to bacteria (including salmonella and staphylococcus)  and their toxins (including botulism). Some strains of E. cou can cause  severe illness. Chemical poisons include heavy metals (see mercury poi�  soning), either from food or leached out from cookware by acidic foods.  Food additives may have a long-term cumulative toxic effect. See also  fish poisoning; mushroom poisoning.</p><p>food preservation Any method by which food is protected against  spoilage by oxidation, bacteria, molds, and microorganisms. Traditional  methods include dehydration, smoking, salting, controlled fermentation  (including pickling), and candying; certain spices have also long been  used as antiseptics and preservatives. Among the modern processes for  food preservation are refrigeration (including freezing), canning, pasteur�  ization, irradiation, and the addition of chemical preservatives.</p><p>fool or jester Comic entertainer whose madness or imbecility, real or  pretended, made him a source of amusement and gave him license to  abuse and poke fun at even his most exalted patrons.

Because of its rapid  spread and impact on animal produc�  tivity, it is considered the most eco�  nomically devastating livestock  disease in the world. It is not a human  health hazard. No effective treatment  exists; vaccines control epidemics  but have not eliminated them.

Only the goalkeeper,  when positioned within the penalty area in front of the goal, may use  hands and arms. The game�s first uniform set of rules was put in place in  1863, when England�s Football Association was created. Professional  leagues began appearing in the late 1880s, first in England and then in  other countries. The Federation Internationale de Football Association  (FIFA) was founded in 1904, and has hosted the World Cup every four  years since 1930. Football has been included in the Olympic Games since  1908. Now played on all continents in over 150 nations, with over 40  million registered players, it is the world�s most popular ball game. See  also Australian Rules football; Gaelic football; football, gridiron; and rugby.</p><p>football, gridiron Game played, predominantly in the U.S. and  Canada, on a rectangular field having two goalposts at each end. In the  U.S. it is played between two teams of 11 players each. The object is to  get an oblong ball, in possession of one side at a time, over a goal line or  between goalposts by running, passing, or kicking. A team must advance  the ball 10 yards in four attempts (called downs) in order to continue to  have the ball for another four downs. A kick through the goalposts (field  goal) counts as three points. A run or completed pass over the goal line  (touchdown) counts as six points.

When the ball is driven across the touch line, it  is put back in play by a throw-in by the opposing side. A ball driven over the goal line but not into the goal by the attacking  team is returned to play with a goal kick by the opposing goalkeeper. A player fouled in the penalty area is awarded a penalty  kick at the goal, which is defended only by the goalkeeper.

He conducted exten�  sive research on mollusks and sea stars, participating in dredgings and  expeditions. While studying ocean life, he developed an interest in the  geographic distribution of animals. Later he divided the plants of Britain  into five well-defined groups, maintaining that most of them, like land  animals, had migrated to the islands over continuous land during three  separate periods: before, during, and after the glacial passage. He held  numerous institutional and academic posts, and he was a major figure in  establishing the fields of oceanography, biogeography, and paleoecology.</p><p>Forbes family U.S. publishing family.

Ford collaborated with Joseph  Conrad on The Inheritors (1901) and Romance (1903). As the founder of  the English Review (1908), he generously encouraged younger writers.  He was gassed and shell-shocked in World War I; after the war he changed  his name to Ford. Of more than 70 published works, his best known are  The Good Soldier (1915), a novel about the demise of aristocratic  England; and the tetralogy Parade�s End� Some Do Not (1924), No More  Parades (1925), A Man Could Stand Up (1926), and Last Post (1928)�  which explores the breakdown of Edwardian culture and the emergence  of new values.</p><p>Ford, Gerald R. in full Gerald Rudolph Ford, Jr. orig.

Ford, Sr., who adopted the boy and gave  him his name. He received degrees from the University of Michigan and  Yale Law School (1941). He joined the Navy during World War II and  served in the South Pacific, attaining the rank of lieutenant commander. He  served in the U.S. House of Representatives for 25 years (1948-73),  becoming Republican minority leader in 1965. After Spiro Agnew resigned  as vice president in 1973, Richard Nixon nominated Ford to fill the vacant  post. When the Watergate scandal forced Nixon to resign. Ford became the  first president who had not been elected to either the vice presidency or the  presidency. A month later he pardoned Nixon; to counter widespread out�  rage, he voluntarily appeared before a House subcommittee to explain his  action. His administration gradually lowered the country�s high rate of  inflation by slowing down the economy, though at the cost of a severe  recession (1974-75) and high unemployment. Ford had a tense relationship  with the Democrat-controlled Congress, vetoing more than 50 bills (more  than 40 were sustained). In September 1975 he was twice the target of  assassination attempts. In the final days of the Vietnam War, he ordered an  airlift of 237,000 anti-communist Vietnamese refugees, most of whom  came to the U.S. The public�s revulsion at the events of Watergate contrib�  uted to his narrow defeat by Jimmy Carter in 1976.</p><p>Ford, Harrison (b.

He also starred in the adven�  ture film Raiders of the Lost Ark (1981) and its sequels (1984, 1989). He  graduated to dramatic roles in Blade Runner (1982), Witness (1985), The  Fugitive (1993), and Clear and Present Danger (1994).

U.S. automotive corporation. Founded in Detroit,  Mich., in 1903 by Henry Ford and a group of investors, the company  introduced the hugely successful Model T in 1908 and by 1923 was pro�  ducing more than half of all U.S. automotive vehicles. Through the Lin�  coln Motor Co. (acquired in 1922), Ford produced luxury Lincolns and  Continentals. After years of declining sales, the Model T was succeeded  by the Model A in 1927; other companies such as General Motors took  the opportunity to make serious inroads into Ford�s dominance. The com�  pany was reincorporated in 1919, with Ford and his family acquiring full  ownership. Henry�s son Edsel served as president 1919�43, and Henry�s  grandson Henry Ford II led the company 1945-79, reviving its fortunes  considerably. Its stock was first publicly traded in 1956. Ford acquired  the British automaker Jaguar in 1989-90, bought the rental car company  Hertz Corp. in 1994, and purchased the automobile division of Volvo in  1999.

Foreign aid may be given in the form of capital transfers or tech�  nical assistance and training for either civilian or military purposes. Its  use in the modern era began in the 18th century, when Prussia subsidized  some of its allies. After World War II, foreign aid developed into a more  sophisticated instrument of foreign policy. International organizations,  such as the United Nations Relief and Rehabilitation Administration, were  created to provide aid to war-ravaged countries and newly freed colonies.

The new volunteer  swears to serve not France but the legion; after serving one enlistment  (five years) with good conduct, foreign-born soldiers are eligible for  French citizenship. Since it keeps a volunteer�s past secret, it has been  romanticized as a haven for those seeking new identities, including crimi�  nals, but most legionnaires are professional soldiers who enjoy combat.

He had won all 40 of his  professional bouts, many by knockout, before he fell in eight rounds to  Muhammad Ali in 1974 in the so-called �Rumble in the Jungle� in Kin�  shasa, Zaire, one of the most famous matches in modern boxing history.  He retired in 1978 but began a remarkable comeback in 1987 at age 38;  he regained the title in 10 rounds against Michael Moorer in 1994 to  become, at 45, the oldest titleholder ever. He announced his retirement  again the next year but fought a few more times in 1996-97. He has been  an ordained minister since 1977.</p><p>forensic medicine Science of applying medical knowledge to legal  questions, recognized as a specialty since the early 19th century. Its pri�  mary tool has always been the autopsy, to identify the dead (e.g., plane-  crash victims) or determine cause of death, which can significantly affect  trials dealing with insurance and inheritance. Forensic psychiatry deter�  mines the mental health of an individual about to stand trial. Forensic  genetics allows paternity to be determined and can identify blood or other  tissue samples as coming from a particular person (see DNA fingerprint�  ing). Forensic toxicology, concerned with such topics as intentional poi�  sonings and drug use, is increasingly important in cases of industrial and  environmental poisoning.</p><p>forensic psychology Application of psychology to legal issues, often  for the purpose of offering expert testimony in a courtroom. In civil and  criminal cases, forensic psychologists may evaluate individuals to deter�  mine questions such as competency to stand trial, relationship of a men�  tal disorder to an accident or crime, and potential for future dangerous  behaviour. In addition to conducting interviews and administering psycho�  logical tests, they usually gather a forensic history, which includes infor�  mation such as hospital records, police reports, and statements of  witnesses. They are also expected to have a grasp of relevant legal ques�  tions. In a child-custody case, a forensic psychologist may be asked to  evaluate home environments, parents, and the character of the child in  order to recommend a custody decision in the child�s best interests.</p><p>forest Complex ecosystem in which trees are the dominant life-form.  Tree-dominated forests can occur wherever the temperatures rise above  50 �F (10 �C) in the warmest months and the annual precipitation is more  than 8 in. (200 mm). They can develop under various conditions within  these limits, and the kind of soil, plant, and animal life differs according  to the extremes of environmental influences. In cool, high-latitude sub�  polar regions, taiga (boreal) forests are dominated by hardy conifers. In  more temperate high-latitude climates, mixed forests of both conifers and  broad-leaved deciduous trees predominate. Broad-leaved deciduous forests  develop in midlatitude climates. In humid equatorial climates, tropical  rainforests develop. There heavy rainfall supports evergreens that have  broad leaves instead of the needle leaves of cooler evergreen forests.  Having extensive vertical layering, forests are among the most complex  ecosystems. Conifer forests have the simplest structure: a tree layer, a  shrub layer that is spotty or even absent, and a ground layer covered with  lichens, Mosses, and liverworts. Deciduous forests are more complex (the  tree canopy is divided into an upper and lower story), and rainforest  canopies are divided into at least three layers. Forest animals have highly  developed hearing, and many are adapted for vertical movement through  the environment. Because food other than ground plants is scarce, many  ground-dwelling animals use forests only for shelter. The forest is nature�s  most efficient ecosystem, with a high rate of photosynthesis affecting both  plant and animal systems in complex organic relationships.</p><p>Forest, Lee De See Lee De Forest</p><p>Forester, C(ecil) S(cott) (b. Aug. 27, 1899, Cairo, Egypt�d. April 2,  1966, Fullerton, Calif., U.S.) British novelist and journalist. Forester  abandoned medicine for writing and achieved success with his first novel,  Payment Deferred (1926). He is best known as the creator of the naval  officer Horatio Hornblower, whose rise from midshipman to admiral and</p><p>peer during the Napoleonic Wars is told in 12 novels published 1937-67.  Many of his novels were adapted into movies, including The African  Queen (1935; film, 1951).</p><p>forestry Management of forested land (see forest), together with asso�  ciated waters and wasteland, primarily for harvesting timber but also for  conservation and recreation purposes. The science of forestry is built  around the principle of multiple-use land management, though the harvest�  ing and replanting of timber are the primary activities. The main objective  is to maintain a continuous supply of timber through carefully planned har�  vest and replacement. The forest manager is also responsible for the appli�  cation of other land controls, including the protection of wildlife and the  implementation of programs to protect the forest from weeds, insects, fun�  gal diseases (see fungus), erosion, and fire. The planned management of  forests originated in early medieval Europe, where laws regulated the fell�  ing of timber and the use of forests for hunting. In the 19th century private  forestry schools were established in Europe; and in 1891 the U.S. govern�  ment authorized its first reserves of forested land. During the 20th century  many nations have undertaken reforestation or afforestation programs.</p><p>forge Open furnace for heating metal ore and metal for working and form�  ing, or a workshop containing forge hearths and related equipment. From  earliest times, smiths (see smithing) heated iron in forges and formed it by  hammering on an anvil. A bellows operated by an assistant or by a foot  treadle provided the forced draft for raising the temperature of the fire.  Later, a waterwheel or animal power was often used to operate the bellows;  modern forges have mechanically powered bellows or rotary blowers.</p><p>forgery In law, the making of a false writing with the intent to defraud.  �Writing� need not be handwriting: the law of forgery also covers print�  ing, engraving, and keyboarding. Counterfeiting is usually regarded as a  specific type of forgery. Checks, negotiable instruments, contracts, wills,  and deeds are examples of documents that may be forged. Evidence may  also be forged. Forgery requires fraudulent intent; it is not forgery to sign  another�s name, fill in blanks, or alter a genuine writing in the honest,  though mistaken, belief that such conduct is authorized.</p><p>forget-me-not Any of about 50 species of plants that make up the  genus Myosotis, in the borage fam�  ily, native to temperate Eurasia and  North America and to mountains of  the Old World tropics. Some are  favoured as garden plants for their  clusters of blue flowers. The woods  forget-me-not (M. sylvatica), like  most other species, changes colour  from pink to blue as the tubular, flar�  ing, five-lobed flower matures.</p><p>forging In metallurgy, the process  of shaping metal and increasing its  strength by hammering or pressing.</p><p>In most forging an upper die is forced  against a heated workpiece posi�  tioned on a stationary lower die. To  increase the force of the blow, power  is sometimes applied to augment  gravity. The number of blows struck  is carefully gauged by the operator to give maximum effect with mini�  mum wear on the die. Forging presses employ hydraulic or mechanical  pressure instead of blows; most can exert only a few hundred tons of  pressure, but giant presses, used for forging parts of jet aircraft, are  capable of up to 50,000 tons of pressure. See also drop forging.</p><p>form In the philosophy of Plato and Aristotle the active, determining  principle of a thing. The term was traditionally used to translate Plato�s  eidos, by which he meant the permanent reality that makes a thing what  it is, in contrast to the particulars that are finite and subject to change.  Each form is the pattern of a particular category of thing in the world;  thus, there are forms of human, stone, shape, colour, beauty, and justice.  Whereas the physical world, perceived with the senses, is in constant flux  and knowledge derived from it restricted and variable, the realm of forms,  apprehensible only by the mind, is eternal and changeless. Particular  things derive what reality they have by �participating� in, or imperfectly  copying, the forms. Aristotle rejected the abstract Platonic notion of form  and argued that every sensible object consists of both matter and form,  neither of which can exist without the other. For Aristotle, the matter of</p><p>Woods forget-me-not [Myosotis sylvat�  ica)</p><p>INGMAR HOLMASEN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>694 i formal system &#x25BA; Forster</p><p>a thing consists of those of its elements which, when the thing has come  into being, may be said to have �become� it; the form of a thing is the  arrangement or organization through which such elements have become  the thing in question. Thus a certain lump of bronze is the matter that,  given a certain form, becomes a statue or, given another, becomes a sword.  The Aristotelian concept of form was adapted and developed by St. Tho�  mas Aquinas and other scholastic philosophers. The Enlightenment phi�  losopher Immanuel Kant used the notion of form to describe the mentally  imposed conditions of sensible experience, namely space and time.</p><p>formal system In logic, a formal language together with a deductive  apparatus by which some well-formed formulas can be derived from oth�  ers. Each formal system has a formal language composed of primitive  symbols that figure in certain rules of formation (statements concerning  the expressions allowable in the system) and a set of theorems developed  by inference from a set of axioms. In an axiomatic system, the primitive  symbols are undefined and all other symbols are defined in terms of them.  In Euclidean geometry, for example, such concepts as �point,� �line,� and  �lies on� are usually posited as primitive terms. From the primitive sym�  bols, certain formulas are defined as well formed, some of which are listed  as axioms; and rules are stated for inferring one formula as a conclusion  from one or more other formulas taken as premises. A theorem within  such a system is a formula capable of proof through a finite sequence of  well-formed formulas, each of which either is an axiom or is validly  inferred from earlier formulas.</p><p>formaldehyde \f6r-'mal-d3- l h!d\ or methanol Vme-tho-.nalX Sim�  plest aldehyde, chemical formula HCHO. Formaldehyde (37%) in water  solution, called formalin, is used as a preservative, an embalming agent,  and a disinfectant. Large amounts of formaldehyde are used in the manu�  facture of various familiar plastics. Bakelite (the first completely synthetic  plastic) is the trademark for formaldehyde and phenol polymer, and For�  mica is the trademark for formaldehyde and urea polymer. The reaction  of formaldehyde with proteins (called amino formylation) leads to its use  in the tanning industry and for treating various vegetable proteins to ren�  der them fibrous.</p><p>formalism See New Criticism</p><p>Formalism or Russian Formalism Russian school of literary criti�  cism that flourished from 1914 to 1928. Making use of the linguistic  theories of Ferdinand de Saussure, Formalists were concerned with what  technical devices make a literary text literary, apart from its psychologi�  cal, sociological, biographical, and historical elements. Though influenced  by the Symbolist movement, they sought to make their analyses more objec�  tive and scientific than those of the Symbolists. The movement was con�  demned by the Soviet authorities in 1929 for its lack of political  perspective. Later it became influential in the West, notably in New Criti�  cism and STRUCTURALISM.</p><p>Forman, Milos (b. Feb. 18, 1932, Caslav, Czech.) Czech-U.S. film  director. He began his career as a scriptwriter, then directed his first fea�  ture film in 1964. Success followed with the ironic comedies Loves of a  Blonde (1965) and The Fireman�s Ball (1967). He moved to the U.S. in  1969 and successfully applied his light touch to the generation gap in  Taking Off (1911), then triumphed with One Flew over the Cuckoo�s Nest  (1975, Academy Award). He directed successful screen adaptations of  theE.L. Doctorow novel Ragtime (1981) and the stage play Amadeus  (1984, Academy Award); his later films include Valmont (1989) and The  People vs. Larry Flynt (1996).</p><p>formes fixes \'f6rm-'feks\ Principal forms of music and poetry in 14th-  and 15th-century France. Three forms predominated. The rondeau fol�  lowed the pattern ABaAabAB\ A (a) and B (b) represent repeated musical  phrases; capital letters indicate repetition of text in a refrain, while low�  ercase letters indicate new text. The ballade employed the pattern aabC.  The virelai used the pattern AbbaA. The trouvere Adam de la Halle (b. c.  1250) wrote the first polyphonic settings of the formes fixes. Guillaume de  Machaut wrote both text and music for many monophonic and polyphonic  chansons in the formes fixes. Later composers, including Guillaume Dufay,  favoured the rondeau.</p><p>formic acid Simplest carboxylic acid, chemical formula HCOOH. It is  secreted by some insects, especially red ants (its name comes from the  Latin word for ant), in their bite or sting. It has many industrial uses, in  textile and leather manufacture, as an industrial solvent, and as an inter�  mediate.</p><p>Formosa See Taiwan  Formosa Strait See Taiwan Strait</p><p>formula weight Sum of the atomic weights of all atoms in a chemical  formula. The term is generally applied to a substance that consists of ions  (see ionic bond) rather than individual molecules (and thus does not have  a molecular weight). An example of such a substance is sodium chloride  (table salt). Such a substance�s chemical formula describes the simplest  ratio of the number of atoms of the constituent elements.

Her family moved to the U.S. in 1945, and  she became a painter before beginning to write plays in the early 1960s.  She wrote some 35 stage works and directed her own works as well as  classic drama. Her innovative dramas have made her one of the most suc�  cessful and frequently produced of Off Broadway playwrights. Her best-  known play, Fefu and Her Friends (1977), explores women�s  relationships with one another.</p><p>Forrest, Edwin (b. March 9, 1806, Philadelphia, Pa., U.S.�d. Dec.  12, 1872, Philadelphia) U.S. actor. He made his stage debut in Philadel�  phia in 1820. He played Othello in New York (1826) to great acclaim and  became known for his Shakespearean roles. His feud with the English  actor William Macready sparked the so-called Astor Place riot (1849), in  which Forrest�s supporters mobbed the theatre where Macready was  appearing. The militia was called out, the rioters attacked, and the militia  fired, killing 22 and wounding 36. Forrest�s reputation never fully recov�  ered; it was further damaged when he filed a divorce suit on grounds of  adultery.</p><p>Forrestal, James V(incent) (b. Feb. 15, 1892, Beacon, N.Y.,  U.S.�d.

After serving in naval aviation in World War I, he resumed his con�  nection with a New York City investment firm, of which he became  president in 1938. Appointed undersecretary of the navy in 1940, he  directed the huge naval expansion and procurement programs of World  War II. He became secretary of the navy in 1944. Appointed the first sec�  retary of defense in 1947, he began to reorganize and coordinate the armed  services. He resigned in 1949. Suffering from a depression similar to battle  fatigue, he entered Bethesda Naval Medical Center; soon after, he plunged  to his death from a window.</p><p>Forrester, Jay Wright (b.

The Atlantic Intracoastal Waterway is connected to the  city�s deepwater port, Port Everglades. The city is interlaced with recre�  ational waterways and has extensive boating facilities, which have given  rise to a marine industry.</p><p>Fort Matanzas National Monument National reserve, northeast�  ern Florida, U.S. Established in 1924 and covering 228 acres (92 hect�  ares), it centres around a Spanish fort on Rattlesnake Island, 14 mi (23  km) south of St. Augustine. Originating in 1569 as a wooden tower and  completed in 1742, the fort is near the site of the slaughter of 300 French  Huguenot colonists by Spaniards in 1565.</p><p>Fort McHenry Military fort and national monument, Baltimore, Mary�  land, U.S. During the War of 1812, the British bombarded it in 1814 but  failed to capture the city it defended. Francis Scott Key witnessed the battle  while being held aboard a British ship, and the sight of the U.S. flag fly�  ing above the fort inspired him to write �The Star-Spangled Banner.� The  fort was used as a federal prison during the American Civil War and then  served as a military post until 1900, when it was abandoned. Occupying  an area of 43 acres (17 hectares), it was named a national park in 1925  and a national monument in 1939.</p><p>Fort Stanwix, Treaties of (1768, 1784) Agreements by which the  Iroquois Confederacy ceded land in what is now western Pennsylvania,  Kentucky, West Virginia, and New York, opening vast tracts to white  exploration and settlement. In 1768 about 3,400 Iroquois gathered at Fort  Stanwix (now Rome), N.Y., to sign a new treaty with the British that  replaced the Proclamation of 1763. Pressure from white settlers and fur  traders for additional land forced the new U.S. government to renegoti�  ate the treaty. Weakened by the frontier campaign against them during the  American Revolution, the Iroquois were persuaded to cede more land and  in 1784 to sign the second treaty, also called the Treaty with the Six  Nations.</p><p>Fort Sumter National Monument Historic site, on a man-made  island at the entrance to the harbour of Charleston, South Carolina, U.S.  Construction of the fort began in 1829 and was still in progress in 1861,  when it became the site of the first engagement (April 12, 1861) of the</p><p>American Civil War. The national monument, established in 1948, also  includes Fort Moultrie on nearby Sullivan�s Island, site of an American  victory against the British (June 28, 1776) in the American Revolution,  when the fort was called Fort Sullivan. The Seminole Indian leader  Osceola is buried there.</p><p>Fort Wayne City (pop., 2000: 205,727), northeastern Indiana, U.S.  Once the chief town of the Miami Indians, it was the site of a French trad�  ing post in the late 17th century. It was taken by the English (1760) and  then by Indians under Pontiac (1763). A log stockade built in 1794 by  Gen. Anthony Wayne gave the town its name. The city�s industrial growth  began with the building of the Wabash and Erie Canal in the 1830s. It  now manufactures a range of machinery, including automotive and elec�  trical equipment. It is the site of educational institutions, including Con�  cordia Theological Seminary (1846) and St. Francis College (1890).  Johnny Appleseed, the pioneer orchard planter, is buried there.</p><p>Fort Worth City (pop., 2000: 534,694), northern Texas, U.S. It lies on  the Trinity River and constitutes the western part of the Dallas-Fort Worth  urban complex. Founded in 1849 as a military outpost against Comanche  raids, it was later a stopover point for cattle drives on the Chisholm Trail.  It became a cattle-shipping boomtown after the railroad arrived in 1876.  Oil finds brought the petroleum-refining industry to Fort Worth in the  1920s, and aircraft manufacturing, which began there during World War  II, has expanded to include aerospace and electronic equipment. Fort  Worth is the seat of Texas Christian University (1873) and Texas Wes�  leyan University (1890), and its attractions include the Amon Carter  Museum.</p><p>Fortaleza \,f6r-t3-'la-z9\ Port city (pop., 2002 est.: 2,219,800), north�  eastern Brazil. It lies at the mouth of the Pajeu River. Originating as a  small village adjoining a Portuguese fort, it took the name of Villa do  Forte da Assumpgao in 1654. In 1810 it became the capital of Ceara cap�  taincy, and in 1823 it was given city status. It became the capital of a  province under the name of Fortaleza Nova de Braganga. It is a textile�  manufacturing centre; its port handles exports.</p><p>Fortas, Abe (b. June 19, 1910, Memphis, Tenn., U.S.�d. April 6, 1982,  Washington, D.C.) U.S. jurist. He graduated from Yale University Law  School (1933), where he studied under William O. Douglas before fol�  lowing him to the Securities and Exchange Commission. As cofounder of a  major Washington, D.C., law firm (1946), he represented some of the  largest U.S. corporations. In 1963 he successfully argued the case of  Gideon v. Wainwright, which established the right of the accused to coun�  sel in criminal trials, regardless of ability to pay. Pres. Lyndon B. Johnson,  a close friend, nominated Fortas to the Supreme Court of the United States  in 1965. Johnson attempted to elevate him to chief justice in 1968, but  his nomination faced a filibuster in the Senate, and Fortas requested that  his name be withdrawn from consideration. In 1969 Fortas resigned from  the Court following a threat of impeachment over his dealings with a fin�  ancier who was subsequently imprisoned for securities violations.</p><p>Fort-de-France \ 1 for-d3- , fra n s\ City (pop., 1999: 94,049), capital of  Martinique, West Indies. Located on the island�s western coast, it was for�  merly called Fort-Royal and has been Martinique�s capital since 1680.  Until 1918, when its commercial growth began, it had an inadequate water  supply, was partly surrounded by swamps, and was notorious for yellow  fever; the swamps have since been drained. It is the French West Indies�  largest town, chief port, and busiest commercial centre and has long shel�  tered the French fleet in the West Indies.

He fled to Scotland after Henry Vi�s defeat in 1461.  Hoping for a restoration of the House of Lancaster, he educated Prince  Edward in France, and he wrote for Edward�s instruction De laudibus  legum Angliae, the first book about law written for the layperson.

The defense of cities and trade centers, usually by high walls, has  been important for centuries. The citadel was the fortress of the ancient  world, appearing in cities of Egypt, Greece, and the Roman empire. By  Classical Greek times, fortress architecture began incorporating ramparts  (walled embankments) and towers. Roman fortresses of the 2nd century  tended to be square or rectangular, and were usually of dressed (cut) stone.  The medieval castle remained almost impregnable until gunpowder came  into use.</p><p>FORTRAN Procedural computer programming language developed for  numerical analysis by John W. Backus and others at IBM in 1957. The  name derives from FORmula TRANslation. For many years it was the  most widely used high-level language for scientific and engineering com�  putations. Though other languages, such as various versions of C, are now  popular for such uses, FORTRAN is still the language of choice for  numerical analysis. It has been revised several times and now includes  capabilities for handling structured data, dynamic (�on-the-fly�) data allo�  cation, recursions (procedures that call themselves), and other features.</p><p>forum In ancient Roman cities, a centrally located open area surrounded  by public buildings and colonnades  and serving as a multipurpose public  gathering place. The forum was an  adaptation of the Greek agora and  acropolis. In Rome the forum  Romanum referred to the flat and for�  merly marshy space between the  Palatine and Capitoline hills. In the  Roman republic, this was the site of  public meetings, law courts, and  gladiatorial games and was lined  with shops and open-air markets.</p><p>Under the Roman empire, when the  forum evolved into a center for reli�  gious and secular ceremonies and  spectacles, it held many of Rome�s  most imposing temples, basilicas,  and monuments. New forums were  built, some devoted to judicial or  administrative affairs and some to  trade. The aesthetic harmony of Tra�  jan�s Forum (2nd century ad), with its complex of buildings and court�  yards and its tiers of shops, influenced many subsequent town planners.</p><p>Foscolo Vf6s-ko-lo\, Ugo orig. Niccolo Foscolo (b. Feb. 6, 1778,  Zacynthus, Venetian republic�d. Sept. 10, 1827, Turnham Green, near  London, Eng.) Italian poet and novelist. His works articulated the feel�  ings of many Italians during the turbulent epoch of the French Revolu�  tion, the Napoleonic Wars, and the restoration of Austrian rule. After  Austria regained Italy in 1814, Foscolo fled first to Switzerland and then  to Britain. His popular novel The Last Letters of Jacopo Ortis (1802) bit�  terly denounced Napoleon�s cession of Venetia to Austria. Among his  poems are the patriotic �Dei sepolcri� (1807) and the acclaimed but unfin�  ished Le grazie (1822).</p><p>Fosse \'fos-e\, Bob orig. Robert Louis Fosse (b. June 23, 1927,  Chicago, Ill., U.S.�d. Sept. 23, 1987, Washington, D.C.) U.S. theatre and  film choreographer and director. Bom into a vaudeville family, Fosse  began dancing professionally at age 13. He won his first Tony Award for  choreographing the Broadway musical The Pajama Game (1954) and  went on to win six more Tonys for his choreography, which was known  for its sensuality, precision, and jazz sensibility. His later hit shows  included Damn Yankees (1955) and Sweet Charity (1966)�both starring  his wife, Gwen Verdon (1925�2000)�as well as Pippin (1973) and  Dancin� (1978). He directed the film musical Cabaret (1972, Academy  Award); his film All That Jazz (1979) was a thinly disguised autobiogra-  phy.</p><p>Fossey, Dian (b. Jan. 16,1932, San Francisco, Calif., U.S.�found dead  Dec. 26, 1985, Volcanoes National Park, Rwanda) U.S. zoologist. She was  working as an occupational therapist when, on a trip to Africa in 1963,  she met Louis Leakey (see Leakey family), who persuaded her to return to</p><p>study the mountain gorilla in its natural habitat. Owing to her patient and  nonthreatening interactions, the gorillas of Rwanda�s Virunga Mountains  became accustomed to her presence, and she was able to gather detailed  knowledge of their habits, communication, and social structure. She  obtained a Ph.D. in 1974 and taught at Cornell University while remain�  ing involved with the Karisoke Research Center in Africa, which she had  established in 1967. She recounted her observations in Gorillas in the Mist  (1983; film, 1988). She actively protected the gorillas from poachers, who  are suspected of her murder at Karisoke.</p><p>fossil Remnant, impression, or trace of an animal or plant of a past geo�  logic age that has been preserved in the Earth�s CRUST. The data recorded  in fossils, known as the fossil record, constitute the primary source of  information about the history of life on the Earth. Only a small fraction  of ancient organisms are preserved as fossils, and usually only organisms  that have a solid skeleton or shell. A shell or bone that is buried quickly  after deposition may retain organic tissue, though it becomes petrified  (converted to a stony substance) over time. Unaltered hard parts, such as  the shells of clams, are relatively common in sedimentary rocks. The soft  parts of animals or plants are rarely preserved. The embedding of insects  in amber and the preservation of mammoths in ice are rare but striking  examples of the fossil preservation of soft tissues. Traces of organisms  may also occur as tracks, trails, or even borings.</p><p>fossil fuel Any of a class of materials of biologic origin occurring within  the Earth�s crust that can be used as a source of energy. Fossil fuels include  coal, petroleum, and natural gas. They all contain carbon and were formed  as a result of geologic processes acting on the remains of (mostly) plants  and animals that lived and died hundreds of millions of years ago. All  fossil fuels can be burned to provide heat, which may be used directly,  as in home heating, or to produce steam to drive a generator for the pro�  duction of electricity. Fossil fuels supply nearly 90% of all the energy  used by industrially developed nations.</p><p>Foster, Abigail Kelley orig. Abigail Kelley (b. Jan. 15, 1810, Pel�  ham, Mass., U.S.�d. Jan. 14, 1887, Worcester, Mass.) U.S. abolitionist.  She became active in a branch of the Female Anti-Slavery Society in the  1830s, and in 1838 she helped William Lloyd Garrison organize the New  England Non-Resistance Society. Her long career as a political lecturer  brought her national fame and notoriety, in part because she addressed  mixed audiences (of both men and women). In 1845 she married Stephen  S. Foster (1809-81), a prominent abolitionist who joined her lecture tour.  In the 1850s she added temperance and women�s rights to her lecture top�  ics.</p><p>Foster, Jodie orig. Alicia Christian Foster (b. Nov. 19, 1962, Los  Angeles, Calif., U.S.) U.S. film actress and director. A professional actress  by age three, she continued to play child roles in family films while earn�  ing praise as a teenage prostitute in Taxi Driver (1976) and a seductive  speakeasy queen in an all-child cast in Bugsy Malone (1976). As an adult  she won acclaim for her nuanced performances in films such as The  Accused (1988, Academy Award), The Silence of the Lambs (1991, Acad�  emy Award), Nell (1994), and Panic Room (2002). She turned to direct�  ing with Little Man Tate (1991) and Home for the Holidays (1995).</p><p>Foster, Stephen (Collins) (b. July 4, 1826, Lawrenceville, Pa.,  U.S.�d. Jan. 13, 1864, New York, N.Y.) U.S. songwriter. He began writ�  ing songs as a child, influenced in part by black church services he  attended with the family�s servant and by songs sung by black labourers.  In 1842 he published �Open Thy Lattice, Love,� and in 1848 he sold �Oh!  Susanna� for $100; it quickly became an international hit. He later entered  into a contract with the publisher Firth, Pond &amp; Co. He was commissioned  to write songs for Edwin P. Christy�s minstrel show; his �Old Folks at  Home� became one of the most popular songs of the century. In 1857,  drinking heavily and in financial difficulties, he sold all rights to his future  songs to his publishers for about $1,900. In 1860 he moved to New York;  he died penniless at age 37, leaving about 200 songs, including �Camp-  town Races,� �My Old Kentucky Home,� �Jeanie with the Light Brown  Hair,� and �Beautiful Dreamer,� and he is universally regarded as the  greatest American songwriter of the 19th century.</p><p>Foster, William Z(ebulon) (b. Feb. 25, 1881, Taunton, Mass.,  U.S.�d. Sept. 1, 1961, Moscow, Russian S.F.S.R.) U.S. labour organizer  and Communist Party leader. He joined the Industrial Workers of the  World in 1909 and became nationally prominent as a leader of the Ameri�  can Federation of Labor in the bloody steel strike of 1919. In 1921 the  Soviet communists chose him as chairman of the U.S. Communist Party,</p><p>Trajan's Forum, Rome, designed by  Apollodorus of Damascus, early 2nd  century ad; one of the semicircular col�  onnaded exedrae</p><p>FOTOTECA UNIONE, ROME</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Foucault &#x25BA; Four Books I 697</p><p>and he ran as its presidential candidate in 1924, 1928, and 1932 on a plat�  form that envisioned the ultimate demise of capitalism and the establish�  ment of a workers� republic. Ill health forced his resignation in 1932.  Soviet dissatisfaction with his successor, Earl Browder, brought him back  as chairman (1945-56), but he fell from favour and was made chairman  emeritus in 1957.</p><p>Foucault \fu-'ko\, Jean (-Bernard-Leon) (b. Sept. 18, 1819, Paris,  France�d. Feb. 11, 1868, Paris) French physicist. Though educated in  medicine, his interests lay in physics. In 1850 he measured the speed of  light with extreme accuracy. He invented the Foucault pendulum and used  it to provide experimental proof that Earth rotates on its axis. He also  discovered the existence of eddy currents (Foucault currents) in a copper  disk moving in a strong magnetic field and invented (1859) a simple but  extremely accurate method of testing telescope mirrors for surface defects.</p><p>Foucault \fu-'koV Michel (Paul) (b. Oct. 15, 1926, Poitiers,  France�d. June 25, 1984, Paris) French structuralist philosopher and his�  torian. A professor at the College de France from 1970, he examined the  codes and concepts by which societies operate, especially the �principles  of exclusion� (such as the distinctions between the sane and the insane)  by which a society defines itself. He theorized that, by surveying social  attitudes in relation to institutions such as asylums, hospitals, and prisons,  one can examine the development and omnipresence of power. His  books�including Madness and Civilization (1961), The Order of Things  (1966), The Archaeology of Knowledge (1969), Discipline and Punish  (1975), and History of Sexuality, 3 vol. (1976-84)�made him one of the  most influential intellectuals of his time. He was an outspoken homo�  sexual, and he died of AIDS. See also structuralism.</p><p>Foucault pendulum \fii-'ko\ Large pendulum that is free to swing in  any direction. As it swings back and forth, the earth rotates beneath it, so  its perpendicular plane of swing rotates in relation to the earth�s surface.  Devised by J.-B.-L. Foucault in 1851, it provided the first laboratory  demonstration that the earth spins on its axis. A Foucault pendulum always  rotates clockwise in the Northern Hemisphere and counterclockwise in  the Southern Hemisphere (a consequence of the Coriolis force). The rate  of rotation depends on the latitude, becoming slower as the pendulum is  placed closer to the equator; at the equator, a Foucault pendulum does not  rotate.</p><p>Fouche \fu-'sha\, Joseph, duke d'Otrante (b. May 21, 1758?, Le  Pellerin, near Nantes, France�d. Dec. 25, 1820, Trieste) French police  organizer. In the French Revolution he was elected to the National Con�  vention and voted for Louis XVI�s death. He was sent on missions to the  provinces to ensure their loyalty, and in Lyon he ordered the massacre of  rebels. He became minister of police in 1799; he supported Napoleon�s  Coup of 18-19 Brumaire and subsequently organized the secret police.  Though Napoleon made him duke d�Otrante in 1809, he had intrigued  against Napoleon from 1807. He was dismissed after ordering a levy of  the national guard (1809) but was brought back several times to under�  take missions for Napoleon. He was minister of police during the Hun�  dred Days and later president of a provisional government, but he was  ultimately exiled as a regicide in 1816.</p><p>foundation Part of a structural system that supports and anchors the  superstructure of a building and transmits its loads directly to the earth.  To prevent damage from repeated freeze-thaw cycles, the bottom of the  foundation must be below the frost line. The foundations of low-rise resi�  dential buildings are nearly all supported on spread footings, wide bases  (usually of concrete) that support walls or piers and distribute the load over  a greater area. A concrete grade beam supported by isolated footings,  piers, or piles may be placed at ground level, especially in a building with�  out a basement, to support the exterior wall. Spread footings are also  used�in greatly enlarged form�for high-rise buildings. Other systems  for supporting heavy loads include piles, concrete caisson columns, and  building directly on exposed rock. In yielding soil, a floating foundation�  consisting of rigid, boxlike structures set at such a depth that the weight  of the soil removed to place it equals the weight of the construction  supported�may be used.</p><p>foundation Nongovernmental, nonprofit organization with assets pro�  vided by donors and managed by its own officials and with income  expended for socially useful puiposes. Foundations can be traced back to  ancient Greece. The late 19th century first saw the establishment of large  foundations with broad purposes and great freedom of action, usually  originating in the fortunes of wealthy industrialists. Today foundations are</p><p>classified as community (having support from many donors and located  in a specific community), corporation-sponsored, and independent.  Notable examples include the Smithsonian Institution (1846), the Carnegie  Corp. of New York (1911), the Rockefeller Foundation (1913), and the Ford  Foundation (1936), one of the largest in the world. Nongovernmental  organizations are known colloquially as �NGOs.�</p><p>foundationalism In epistemology, the view that some beliefs can jus�  tifiably be held directly (e.g., on the basis of sense perception or rational  intuition) and not by inference from other justified beliefs. Other types of  beliefs (e.g., beliefs about material objects or about theoretical entities of  science) are not regarded as basic or foundational in this way but are held  to require inferential support. Foundationalists have typically recognized  self-evident truths and reports of sense-data as basic, in the sense that they  do not need support from other beliefs. Such beliefs thus provide the  foundations on which the edifice of knowledge can properly be built. See  also COHERENTISM.</p><p>founding Process of pouring molten metal into a mold. When the metal  solidifies, the result is a casting, a metal object conforming to that shape.  Multitudinous metal objects are molded at some point during their manu�  facture. Modern foundries capable of large-scale production are charac�  terized by a high degree of mechanization, automation, and robotics;  microprocessors accurately control the automated systems. Advances in  chemical binders have resulted in stronger molds and cores and in more  accurate castings. Accuracy and purity are increased in vacuum condi�  tions, and further advances are expected from zero-gravity casting in  space.</p><p>fountain Artificially produced jet of water, and the structure from which  it rises. Fountains have been an important feature of landscape design  since ancient times. Displaced for a time by the medieval well, the foun�  tain reemerged in the late Middle Ages. It reached its peak in the Renais�  sance and Baroque eras, with designs in which sculpture became  prominent (e.g., Rome�s Trevi Fountain). Supplying water through con�  duits to multiple fountains, as at the Palace of Versailles, was an impor�  tant feat. In Muslim countries, fountains for drinking and for ablutions  are of great importance. A common type is the simple spout and basin  enclosed in a graceful niche; more ambitious designs take the form of a  richly decorated pavilion.</p><p>Fouquet \fu-'ke\, Jean (b. c. 1420, Tours, Fr.�d. c. 1481, Tours)  French painter. Little is known about his early life or training, but a trip  to Rome in the 1440s exposed him to Italian Renaissance art; upon his  return to Tours, Fouquet created a new style, combining the experiments  of Italian painting with the exquisite precision of characterization and  detail of Flemish art. His most famous works were produced for Charles  VII�s secretary, Etienne Chevalier: a large Book of Hours with some 60  full-page miniatures and a diptych from Notre-Dame at Melun (c. 1450),  with Chevalier�s portrait on one panel and a Madonna and Child on the  other. The altarpiece of the Pieta in the church at Nouans is his only  monumental painting. In 1475 he became royal painter to Louis XI. He  broadened the range of miniature painting to include vast panoramas of  architecture and landscape and made brilliant use of aerial perspective and  colour tonality. He was the preeminent French painter of the 15th century.</p><p>Fouquet \fu-'ke\, Nicolas (b. 1615, Paris, France�d. March 23, 1680,  Pignerol) French finance minister (1653-61) in the early years of the reign  of Louis XIV. He was a wealthy supporter of the powerful Cardinal Maz-  arin and of the royal government during the turmoil of the Fronde (1648-  53), when he lent large sums to the treasury. In 1653 he was appointed  superintendent of finance. After Mazarin�s death (1661) Jean-Baptiste Col�  bert sought to succeed Fouquet by destroying his reputation with the king.  Fouquet was arrested for embezzlement, while Colbert suppressed papers  that would have absolved him. Though public opinion was in his favour,  he was sentenced in 1664 to imprisonment in the fortress of Pignerol,  where he died.</p><p>Four Books Chinese Sishu Ancient Confucian texts used as the basis  of study for civil service examinations (see Chinese examination system) in  China (1313-1905). They served as an introduction to Confucianism and  were traditionally studied before the more difficult Five Classics. The pub�  lication of the four texts as a unit in 1190 with commentaries by Zhu Xi  helped revitalize Confucianism in China. The texts are Daxue, Zhong-  yong, Lunyu (the Analects, which reputedly contains direct quotations  from Confucius and is deemed the most reliable source of his teachings),  and Mencius.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>698 i four-colour map problem &#x25BA; Fourth Republic</p><p>four-colour map problem In topology, a long-standing conjecture  asserting that no more than four colours are required to shade in any map  such that each adjacent region is coloured differently.

An extremely antidemocratic coun�  cil, it was soon replaced, at the insistence of the Athenian fleet, by a more  moderate oligarchy, the Five Thousand. The new council lasted only 10  months, but full democracy was restored in 410 and a commission set up  to prevent a recurrence.

The truths are  (1) existence is suffering; (2) desire, or thirst, is its cause; (3) the cessa�  tion of suffering is possible; and (4) the way to accomplish this is to fol�  low the Eightfold Path. Though differently interpreted, these four truths  are recognized by virtually all Buddhist schools.</p><p>Fourdrinier \ 1 for-dr3-'nir\ machine Machine for producing paper,  paperboard, and other fibreboards, consisting of a moving endless belt of  wire or plastic screen that receives a mixture of pulp and water and allows  excess water to drain off, forming a continuous sheet for further drying  by suction, pressure, and heat. Calendering smooths the paper or board  and imparts gloss or other desired finish to the surface. The first machine  to produce a continuous web (roll), the Fourdrinier machine was patented  in France in 1799 by Louis Robert and later improved in England by  Henry (1766-1854) and Sealy (died 1847) Fourdrinier. With further  improvements over the years, it is still in use today.</p><p>Fourier \f\ir-ya.,\English\ , fur-e-,a\, (Francois-Marie-) Charles (b.</p><p>April 7, 1772, Besangon, France�d.</p><p>Oct. 10, 1837, Paris) French social  theorist. He advocated a reconstruc�  tion of society based on communal  associations of producers known as  phalanges (phalanxes). His system  became known as Fourierism. He  felt that phalanges would distribute  wealth more equitably than would  capitalism and that they would con�  tribute both to a cooperative lifestyle  and to individual self-fulfillment.</p><p>After inheriting his mother�s estate  in 1812 , he devoted himself to writ�  ing and refining his theories.

While an engineer on Napoleon�s Egyptian expedition, he con�  ducted (1798-1801) anthropological investigations and wrote the preface  to the monumental Description de I�Egypte, whose publication he over�  saw (1809-28). In 1808 he was created a baron by Napoleon. In math�  ematics he is primarily known for his work in heat conduction (1807-22),  for his use of the Fourier series to solve differential equations, and for the</p><p>related concept of the Fourier trans�  form. As a scientist and humanist, he  epitomized the spirit of French intel-  lectualism of the Revolutionary era.</p><p>Fourier series In mathematics, an  infinite series used to solve special  types of differential equations. It con�  sists of an infinite sum of sines and  cosines, and because it is periodic  (i.e., its values repeat over fixed  intervals), it is a useful tool in ana�  lyzing periodic functions. Though  investigated by Leonhard Euler,  among others, the idea was named  for Joseph Fourier, who fully explored  its consequences, including impor�  tant applications in engineering, par�  ticularly in heat conduction.</p><p>Fourier transform In math�  ematical analysis, an integral transform useful in solving certain types of  partial differential equations.

Oct. 31, 1802, Saint-Etienne,  France�d. July 31, 1867, Paris) French inventor of the water turbine. He  first built a small, 6-horsepower unit in which water was directed outward  from a central source onto blades or vanes set at angles in a rotor, and he  eventually produced a turbine capable of 2,300 revolutions per minute,  80% efficiency, and 60 horsepower, with a wheel 1 ft (30 cm) in diameter  weighing 40 lbs (18 kg). Besides its more obvious advantages over the  waterwheel, Fourneyron�s turbine could be installed horizontally with a  vertical shaft. Immediately successful, it powered industry in continental  Europe and the U.S., notably the New England textile industry. In 1895  Fourneyron turbines were installed on the U.S. side of Niagara Falls to  generate electric power.</p><p>four-o'clock Ornamental perennial plant (Mirabilis jalapa\ family  Nyctaginaceae), also called marvel-of-Peru or beauty-of-the-night, native  to the tropical New World.

His theory of element generation (nucleosynthesis) suggests that, as stars  evolve, chemical elements are synthesized progressively (light to heavy)  by means of nuclear fusion that also produces light and heat and that the  heaviest elements are synthesized in supernovas. For his theory he shared  a 1983 Nobel Prize with Subrahmanyan Chandrasekhar. He is also known  for his work in radio astronomy with Fred Hoyle.</p><p>Fowles, John (Robert) (b.

Foxes have long fur, pointed ears, relatively short legs, and a  naiTOw snout. They have often been hunted for sport or fur. In a more  restricted sense, the name refers to about 10 species of true foxes (genus  Vulpes), especially both the Old and New World red foxes. See also Arc�  tic FOX, BAT-EARED FOX, FENNEC, GRAY FOX.</p><p>Fox North American Indian people living mainly in Oklahoma but also  in Kansas, Nebraska, and Iowa, U.S. They are distinct from but united  with the Sauk (Sac) as the Sac and Fox Nation. Their name for them�  selves is Mesquakie (or Meshkwahkihaki, meaning �People of the Red  Earth�), and their language is of the Algonquian family. They are believed  to have originated from the Great Lakes region. Both the Sauk and the  Fox were living in Wisconsin at the time of first European contact. Their  permanent villages�near fields in which women cultivated corn, beans,  and squash�were occupied in summer; in winter they hunted bison on  the prairies. A chief and council administered tribal affairs. Families were  grouped into clans. Religious life centred on the Grand Medicine Soci�  ety, whose members enlisted supernatural aid to heal the sick and ensure  success in warfare. In the 18th century the Fox joined with the Sauk to  war against the French and English. Though unconquered, they retreated  south to Illinois and later west to Iowa. In 1832 Black Hawk led a group  of Fox and Sauk in an unsuccessful attempt to return to their Illinois lands.  In the 2000 U.S. census some 4,200 people claimed Sac and Fox descent.</p><p>Fox, Charles James (b. Jan. 24, 1749, London, Eng.�d. Sept. 13,  1806, Chiswick, Devon) British politician. He entered Parliament in 1768  and became leader of the Whigs in the House of Commons, where he  used his brilliant oratorical skills to strongly oppose Britain�s policy  toward the American colonies. Almost always in the political opposition,  he conducted a vendetta against George III and was later an enemy of Wil�  liam Pin. He served as Britain�s first foreign secretary (1782, 1783, 1806).  He achieved two important reforms by steering through Parliament a  resolution pledging it to end the slave trade and by enacting the 1792 Libel  Act, which restored to juries their right to decide what constituted libel  and whether or not a defendant was guilty of it. He is remembered as a  great champion of liberty.</p><p>Fox, George (b. July 1624, Drayton-in-the-Clay, Leicestershire,  Eng.�d. Jan. 13, 1691, London) English preacher and founder of the  Society of Friends, or Quakers. The son of a weaver, he left home at age  18 in search of religious experience. Probably beginning as a Puritan, he  reacted even more strongly than the Puritans against the tradition of the  Church of England and came to regard personal experience as the true  source of authority, placing God-given �inward light,� or inspiration,  above creeds and scripture. He traveled the countryside on foot, preach�  ing to small groups, and he and other preachers established congregations.  The Society of Friends arose in the 1650s. The Quakers� denunciation of  ministers and public officials and their refusal to pay tithes or take oaths  led to persecution, and Fox was imprisoned eight times between 1649 and  1673. He made missionary trips to Ireland, the Caribbean islands. North  America, and northern Europe. His Journal gives an account of his life  and of the rise of Quakerism.</p><p>Fox, Vicente Quesada (b.

He later worked for  the Coca-Cola Company, serving as its chief executive in Mexico (1975�  79). In 1987 he joined the National Action Party (PAN) and the follow�  ing year was elected to the national Chamber of Deputies.

The network gradually expanded its  broadcast hours to seven nights a week and gained more affiliates to make  it available across the U.S. Concentrating on shows that appealed to afflu�  ent young viewers, it added programming divisions for children, sports,  and news in the 1990s.</p><p>fox terrier Well-known breed of dog developed in England to drive  foxes from their dens. The wire-  haired variety was developed from a  rough-coated black-and-tan terrier;  the smooth-haired variety was devel�  oped from the beagle, greyhound, bull  terrier, and a smooth-coated black-  and-tan terrier.

In  England, home of the sport, it dates from at least the 15th century, when  it probably developed out of stag and hare hunting. Modern foxhunting  became popular among the upper classes in the 19th century. A hunt is  led by the master; the dogs (usually 15-20 matched pairs) are controlled  by the huntsman and two or three assistants. The hunt may take place on  any grounds (woodlands, heath, or fields) where a fox is suspected to be.  The riders, outfitted in distinctive scarlet coats, meet at a host�s house,  and the hounds are sent off to search out the fox; when it is found, the  hunt begins. The fox is chased until it either escapes or is cornered and  killed. Although foxhunting reached its peak in popularity before World  War I, it continued to be practiced afterward, most notably in the United  Kingdom. However, growing opposition to the sport, largely based on  charges of animal cruelty and elitism, led to its ban in Scotland (2002)  and in England and Wales (2005).</p><p>Foxx, Jimmie orig.

Foxx batted right-handed and  played mostly at first base, princi�  pally with the Philadelphia Athletics  (1925�35) and the Boston Red Sox  (1936-42). In two of his 20 seasons  he hit over 50 home runs. His career  home runs totaled 534 when he  retired in 1945, making him the sec�  ond man in major-league history  (after Babe Ruth) to hit 500 home  runs.</p><p>Foyt, A(nthony) J(oseph), Jr.</p><p>(b.

He  was national champion stock-car  driver in 1968, 1978, and 1979, and  he also amassed numerous wins in  sports- and midget-car racing.</p><p>Fracastoro Vfra-ka-'sto-roV, Girolamo Latin Hieronymus Fra-  castorius (b. c. 1478, Verona, Republic of Venice�d. Aug. 8, 1553,  Caffi, near Verona) Italian physician, poet, astronomer, and geologist. He  is best known for Syphilis, or the French Disease (1530), an account in  rhyme of the disease he named. His intense study of epidemic diseases  led to his On Contagion and Contagious Diseases (1546). The first sci�  entific statement of the true nature of contagion, infection, disease germs,  and modes of disease transmission, it stated that each disease is caused  by a different type of rapidly multiplying minute body, transmitted by  direct contact, by carriers such as soiled clothing or through the air.  Widely praised in his time, Fracastoro�s theory, soon obscured by the  mystical doctrines of Paracelsus, fell into general disrepute until Louis Pas�  teur and Robert Koch proved it 300 years later.</p><p>fractal geometry In mathematics, the study of complex shapes with  the property of self-similarity, known as fractals. Rather like holograms  that store the entire image in each part of the image, any part of a fractal  can be repeatedly magnified, with each magnification resembling all or  part of the original fractal. This phenomenon can be seen in objects like  snowflakes and tree bark. The term fractal was coined by Benoit B. Man�  delbrot in 1975. This new system of geometry has had a significant impact  on such diverse fields as physical chemistry, physiology, and fluid  mechanics; fractals can describe irregularly shaped objects or spatially  nonuniform phenomena that cannot be described by Euclidean geometry.  Fractal simulations have been used to plot the distributions of galactic  clusters and to generate lifelike images of complicated, irregular natural  objects, including rugged terrains and foliage used in films. See also chaos  THEORY.</p><p>fraction In arithmetic, a number expressed as a quotient, in which a  numerator is divided by a denominator. In a simple fraction, both are inte�  gers. A complex fraction has a fraction in the numerator or denominator.  In a proper fraction, the numerator is less than the denominator. If the  numerator is greater, it is called an improper fraction and can also be  written as a mixed number�a whole-number quotient with a proper-  fraction remainder. Any fraction can be written in decimal form by car�  rying out the division of the numerator by the denominator. The result  may end at some point, or one or more digits may repeat without end.</p><p>fracture In mineralogy, the appearance of a surface broken in directions  other than along cleavage planes. There are several kinds of fractures:  conchoidal (curved concavities resembling shells, as in glass); even  (rough, approximately plane surfaces); uneven (rough and completely  irregular surfaces, the commonest type); hackly (sharp edges and jagged  points and depressions); and splintery (partially separated splinters or  fibres).</p><p>fracture In engineering, rupture of a material too weak to sustain the  forces on it. A fracture of the workpiece during forming can result from  flaws in the metal; these often consist of nonmetallic inclusions such as  oxides or sulfides trapped in the metal during refining. Laps are another  type of flaw, in which part of a metal piece is inadvertently folded over  on itself but the two sides of the fold are not completely welded together.  Structural and machine parts subject to vibrations and other cyclic load�  ing must be designed to avoid fatigue fracture. See also ductility, metal�  lurgy, strength of materials, testing machine.</p><p>fracture Break in a bone, caused by stress. It causes pain, tenderness,  and inability to use the part with the fracture. The site appears deformed,  swollen, and discoloured, and the bone moves in abnormal ways. It must  be protected from weight bearing and movement between the broken ends  while it heals, producing puttylike new tissue that hardens to join the bro�  ken pieces together. Complications include failure to heal, healing in the  wrong position, and loss of function despite good healing. Fractures in  joints present a particularly serious problem, often requiring surgery.

He subse�  quently won a Prix de Rome, and  while in Italy (1756-61) he traveled  extensively and executed many  sketches of the countryside, espe�  cially the gardens at the Villa d�Este  at Tivoli, and developed a great  admiration for the work of Giovanni  Battista Tiepolo. In 1765 his large his�  torical painting Coresus Sacrifices  Himself to Save Callirhoe was pur�  chased for Louis XV and won Frago�  nard election to the French Royal  Academy.

Rigid frames have fixed joints that enable the  frames to resist lateral forces; other frames require diagonal bracing or  shear walls and diaphragms for lateral stability. Heavy timber framing was  the most common type of construction in East Asia and northern Europe  from prehistoric times to the mid-19th century. It was supplanted by the  balloon frame and the platform frame (see ught-frame construction).  Steel�s strength, when used in steel framing, made possible buildings with  longer spans.

Culturally, France has enjoyed a  significant role in the world from the early Middle Ages. Archaeological  excavations in France indicate continuous settlement from Paleolithic  times. By the 5th century bc the Gauls migrated south from the Rhine  River valley to the Mediterranean coast of modern France, and in 600 bc  Ionian Greeks established several settlements, including one at Marseille.  Juuus Caesar completed the Roman conquest of Gaul in 50 bc. During the  6th century ad the Salian Franks ruled; by the 8th century power had  passed to the Carolingians, so named for the influential reign of Charle�  magne. The Hundred Years' War (1337-1453) resulted in the return to  France of land that had been held by England; by the end of the 15th  century, France approximated its modem boundaries. The 16th century  was marked by the Wars of Religion between Protestants (Huguenots) and  Roman Catholics. Henry IV� s Edict of Nantes (1598) granted substantial  religious toleration, but this was revoked in 1685 by Louis XIV, who helped  to raise monarchical absolutism to new heights. In 1789 the French Revo�  lution proclaimed the rights of the individual and destroyed the ancien  regime. Under the rule of Napoleon (1799-1814/15), France fought to  expand its dominion. It then became a monarchy again until the found�  ing of the Second Republic (1848-52), after which Napoleon III ruled as  emperor before the creation of the Third Republic in 1871. World War I  (1914-18) ravaged the northern part of France. After Nazi Germany�s  invasion of France during World War II, the collaborationist Vichy regime  governed. Liberated by Allied and Free French forces in 1944, France  restored parliamentary democracy under the Fourth Republic. A costly war  in Indochina (see Indochina wars) and rising nationalism in French colo�  nies during the 1950s overwhelmed the Fourth Republic. The Fifth Repub�  lic officially began in January 1959 under Charles de Gaulle, who presided  over the dissolution of most of France�s overseas colonies (see Algerian  War; French Equatorial Africa; French West Africa). In 1981 France  elected its first socialist president, Francois Mitterrand. At various times  from 1986 through the beginning of the 21st century, France balanced a  form of divided government known as �cohabitation,� with a president  and prime minister of different political parties.</p><p>France Vfra n s\, Anatole orig.

He succeeded his father, Leopold  II. as emperor in 1792. An absolutist who hated constitutionalism, Fran�  cis supported the first coalition war against France (1792-97). Twice  defeated by France, he elevated Austria to an empire (1804) soon after  Napoleon made himself emperor of France. Napoleon dictated the disso�  lution of the Holy Roman Empire, and Francis abdicated in 1806. Though  he despised Napoleon, he was forced by reasons of state to marry his  daughter Marie-Louise to Napoleon in 1810. Francis helped destroy Napo�  leon�s power in battles in 1813-14. After the Congress of Vienna (1815),  Francis supported his chief minister, Klemens, prince von Metternich, in  instituting a conservative and restrictive political system in Germany and  Europe.</p><p>Francis II Italian Francesco \fran-'cha-sko\ (b. Jan. 16, 1836, King�  dom of Naples�d. Dec. 27, 1894, Arco, Italy) King of the Two Sicilies  (1859-60), the last of the Bourbon kings of Naples. He succeeded his  father, Ferdinand II. in 1859 and on his accession rejected proposals made  by Count Cavour that he join Piedmont-Sardinia in the war against Aus�  tria and grant liberal reforms on its conclusion. Alarmed by the invasion  of Sicily by Giuseppe de Garibaldi in 1860, Francis capitulated to the lib�  erals in his kingdom and restored the constitution of 1848, granted free�  dom of the press, and promised new elections. It was too late to save the  monarchy, however; the Bourbon forces were defeated by Garibaldi, and  less than a month later Francis was deposed by a plebiscite. He then lived  in exile in Rome and Paris.</p><p>Francis, James Bicheno (b. May 18, 1815, Southleigh, Devon,  Eng.�d. Sept. 18, 1892, Lowell, Mass., U.S.) British-U.S. hydraulic engi�  neer. He immigrated to the U.S. in 1833 and at 22 became chief engineer  of the Proprietors of the Locks and Canals on the Merrimack River. In  40 years of managing the company�s waterpower interests and advising  manufacturers on waterpower, he contributed greatly to the rise of Lowell  as an industrial centre. He invented the mixed-flow, or Francis, turbine  used for low-pressure installations. He is also known for his formulas for  the flow of water over weirs and many other studies in hydraulics. He was  considered one of the foremost civil engineers of his time.</p><p>Francis de Sales, Saint (b. Aug. 21, 1567, Thorens-Glieres,  Savoy�d. Dec. 28, 1622, Lyon; canonized 1665; feast day January 24)  Roman Catholic bishop of Geneva and Doctor of the Church. He studied  in Paris and at Padua and was ordained in 1593. He was consecrated  bishop of Geneva in 1602. In 1610, with St. Jane Frances de Chantal, he  founded the Visitation of Holy Mary (the Visitation Nuns), a teaching  order. His Introduction to a Devout Life (1609) argued that spiritual per�  fection is possible for ordinary individuals busy with worldly affairs. He  was an active opponent of Calvinism. Pius XI named him patron saint of  writers.</p><p>Francis Ferdinand German Franz Ferdinand (b. Dec. 18, 1863,  Graz, Austria�d. June 28, 1914, Sarajevo, Bosnia and Herzegovina)  Archduke of Austria, whose assassination was the immediate cause of  World War I. Nephew of Emperor Francis Joseph, he became heir appar�  ent in 1896. His desire to marry Sophie, countess von Chotek, a lady-in-  waiting, brought him into sharp conflict with the emperor, and the  marriage was only allowed after he agreed to renounce his future chil�  dren�s rights to the throne. From 1906 he exerted influence in military  matters and became inspector general of the army (1913). While on an  official visit in Sarajevo in June 1914, he and his wife were assassinated  by the Serbian nationalist Gavrilo Princip. In July Austria declared war  against Serbia, precipitating World War I.</p><p>King Francis I of France, portrait by  Pierre Dumonstier, after a drawing by  Jean Clouet; in the Bibliotheque Natio-  nale, Paris.</p><p>COURTESY OF THE BIBLIOTHEQUE NATIONALE, PARIS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Francis Joseph &gt; Franco-Russian Alliance I 703</p><p>Francis Joseph German Franz Josef (b.

He  became emperor during the Revolu�  tions of 1848 after the abdication of  his uncle, Ferdinand I. With his prime  minister, Felix, prince zu Schwarzen-  berg, he achieved a powerful position  for Austria, in particular with the  Punctation of Olmutz convention in  1850. His harsh, absolutist rule  within Austria produced a strong  central government but also led to  rioting and an assassination attempt.</p><p>Following Austria�s defeat by Prus�  sia in the Seven Weeks' War (1866),  he responded to Hungarian national  unrest by accepting the Compromise  of 1867. He adhered to the Three  Emperors' League and formed an alli�  ance with Prussian-led Germany that  led to the Triple Alliance (1882). In  1898 his wife was assassinated, and in 1889 his son Rudolf, his heir  apparent, died in a suicide love pact. In 1914 his ultimatum to Serbia fol�  lowing the murder of the next heir presumptive, Francis Ferdinand, led  Austria and Germany into World War I.</p><p>Francis of Assisi, Saint orig.

Oct. 3, 1226, Assisi;  canonized July 16, 1228; feast day  October 4) Italian saint and founder  of the Franciscan religious order.</p><p>Born into a wealthy family, he was a  soldier and prisoner of war before he  experienced a conversion in his early  20s. He sold his property, gave the  proceeds to the church, and began a  life of poverty and devoutness. He  soon attracted followers, whom he  sent to preach throughout Europe,  and in 1209 Innocent III gave  approval for the Franciscan order.</p><p>The Rule of St. Francis stressed the  need to imitate the life of Jesus. In  many ways a mystic, Francis viewed  all nature as a mirror of God, calling  all creatures his brothers and sisters.</p><p>In 1212 he allowed formation of an  order for women, called the Poor  Clares. In 1219 he went to Egypt,  preached to the sultan, and visited  the holy places of Jerusalem. In  1224, after a vision, he became the  first person to receive the stigmata.</p><p>His influence helped restore popular  faith in a church much corrupted by wealth and political aspirations.</p><p>Franciscan Member of a Christian religious order dedicated to the  apostolic life of poverty and preaching founded in 1209 by St. Francis of  Assisi. The Franciscans actually consist of three orders. The First Order  comprises priests and lay brothers who have sworn to a life of prayer,  preaching, and penance. The Second Order (founded 1212) consists of  cloistered nuns known as the Poor Clares. The Third Order consists of  religious members and laypersons who observe Franciscan principles in  teaching, charity, and social service. The Rule of St. Francis stipulated  that Franciscan friars could own no property of any kind, either individu�  ally or communally. The friars wandered and preached among the people,  helping the poor and sick. Their impact was immense; within 10 years  they numbered 5,000. A milder version of the rule was approved in 1223,  and after the death of St. Francis in 1226 the order was divided by con�  flicts over the vow of poverty. A moderate interpretation of the rule was  established while St. Bonaventure was minister general of the order (1257-</p><p>74), and the friars spread throughout Europe, their missionaries penetrat�  ing as far as Syria and Africa. Though continuing controversy over the  definition of poverty led to the intervention of the Pope John XXII, who  persecuted the advocates of strict poverty, and to divisions of the order  that lasted into the 19th century, the Franciscans flourished. They remain  the largest Roman Catholic religious order.</p><p>Franck VfraqkV, Cesarf-Auguste) (b. Dec. 10, 1822, Liege,  Neth.�d. Nov. 8, 1890, Paris, France) Belgian-French composer. A piano  prodigy, he arrived in Paris at age 14 to study at the Paris Conservatoire.  In 1858 he became organist at the large church of Sainte-Clotilde, where  he would remain the rest of his life. In 1872 he became professor of organ  at the Conservatoire. His compositions, which tend to be serious, German-  influenced, and often religious, include the famous Symphony in D Minor  (1888); the tone poems Les Eolides (1876), Le Chasseur maudit (1882),  and Psyche (1888); the oratorio Les Beatitudes (1879); chamber works  including a piano quintet (1879), a violin sonata (1886), and a string  quartet (1889); and many works for organ and piano.</p><p>Franco Yfraq-koA English Vfraq-koV Francisco in full Francisco  Paulino Hermenegildo Teodulo Franco Bahamonde (b. Dec.  4, 1892, El Ferrol, Spain�d. Nov. 20, 1975, Madrid) Spanish general and  head of the government of Spain (1939-75). A career army officer, he was  noted as a skillful leader and became army chief of staff in 1935. He joined  the insurgents in the Spanish Civil War and was named El Caudillo (�The  Leader�) of the Nationalist forces (1936). In 1937 he reorganized the fas�  cist Falange party into a more pluralistic group and made it the regime�s  official political movement. Though in sympathy with the Axis Powers in  World War II, Spain remained formally neutral, but after the war Franco  was ostracized as the �last surviving fascist dictator.� Relations with other  nations regularized with the onset of the Cold War, as Franco became a  leading anticommunist statesman. In the 1950s and �60s, his domestic  policies moderated, and Spain made great economic progress. He pro�  vided for his succession by an official referendum in 1947 that made the  Spanish state a monarchy, ratifying his powers as regent for life. In 1969  he designated Prince Juan Carlos as his successor.</p><p>Franco-Cantabrian \kan-'ta-bre-on\ school Oldest and most com�  plete of several artistic traditions of the Paleolithic Period that flourished  in southwestern France and the Cantabrian Mountains of northern Spain  c. 40,000-10,000 bc. It developed in huge limestone caves, such as Alta-  mira and Lascaux Grotto, which served as ceremonial centres for ancient  hunters. Inspired by magical-religious beliefs, the art consists of large  numbers of cave paintings of single, lively, unrelated animals, which may  have been used in rituals invoking success in the hunt and animal fertil�  ity. Small carved figurines incised with linear details have also been found.</p><p>Franco-Prussian War or Franco-German War (1870-71) War  in which a coalition of German states led by Prussia defeated France,  ending French hegemony in continental Europe and creating a unified  Germany. The immediate cause was the candidacy of Prince Leopold of  Hohenzollern-Sigmaringen for the Spanish throne, which raised the pos�  sibility of a combination of Prussia and Spain against France. Following  diplomatic maneuvers to block Leopold�s candidacy, the Prussian chan�  cellor Otto von Bismarck published the Ems Telegram to provoke the French  government into declaring war, which it did. The other German states  sided with Prussia, and German troops under Gen. Helmuth von Moltke,  superior in numbers and organization, scored repeated victories. After  Napoleon III surrendered at the Battle of Sedan, French resistance was car�  ried on by a new government, which deposed the emperor and established  the Third Republic. Paris surrendered, but while treaty negotiations were  going on, an insurrection by radicals in Paris created a short-lived gov�  ernment, the Paris Commune. After its suppression, a harsh peace treaty  was implemented: Germany annexed Alsace and half of Lorraine, and  France was occupied until a large indemnity was paid. The German  empire was established when William I of Prussia was proclaimed German  emperor in 1871. The peace was an unstable one, marked by France�s  determination to recover Alsace-Lorraine and Germany�s mounting impe�  rialism, led by Prussian militarism. Their mutual animosity was a driving  force that led to World War I.</p><p>Franco-Russian Alliance or Dual Alliance (1894) Political and  military pact between France and Russia that was one of the basic Euro�  pean alignments of the pre-World War I era.

A medi�  eval duchy, after ad 843 it was the German part of the former Carolin-  gian empire. After the Carolingian line died out, Franconia�s duke became  the first elected German king, as Conrad I. The duchy was then divided  into Rhenish (west) and East Franconia, the latter alone retaining the name  of Franconia after the 12th century.

The Franks lived east of the Rhine  River in the 3rd century and came under Roman influence. They gained  control of northern Gaul by 494 and southern Gaul by 507, and the con�  version of their leader Clovis I to Catholic Christianity won them the sup�  port of the clergy and the Gallo-Roman population in Gaul. The Franks  established one of the most powerful kingdoms of the early Middle Ages,  ruling lands in present-day France (to which they gave their name), Bel�  gium, and western Germany. The Merovingian dynasty to which Clovis  belonged was succeeded by the Carolingian dynasty, whose most notable  ruler, Charlemagne, created a great empire across Christian Europe. The  division of the realm in the 9th century and the subsequent dissolution of  a unified Frankish empire foreshadowed the formation of the modern  countries of western Europe.</p><p>Frank \'fraqk,\ English \'fraqk\, Anne(lies Marie) (b.

Frank was a young Jewish girl who  kept a record of the two years her family spent in hiding in Amsterdam  to escape Nazi persecution. After their discovery by the Gestapo in 1944,  the family was transported to concentration camps; Anne died of typhus  at Bergen-Belsen. Friends searching the hiding place found her diary,  which her father published as The Diary of a Young Girl (1947). Preco�  cious in style and insight, it traces her emotional growth amid adversity  and is a classic of war literature.</p><p>Frank \'fraqk\, Jacob orig. Jacob Leibowicz (b. 1726, Berezanka  or Korolowka, Galicia, Pol.�d. Dec. 10, 1791, Offenbach, Hessen) Jew�  ish false Messiah. He was an uneducated visionary who claimed to be the  reincarnation of Shabbetai Tzevi. He proclaimed himself messiah in 1751  and founded the Frankist, or Zoharist, sect, based on the Sefer ha-zohar,  which he sought to put in the place of the Torah. The sect rejected tra�  ditional Judaism, and their practices, including orgiastic rites, led the  Jewish community to excommunicate them in 1756. Protected by Roman  Catholic authorities, who hoped Frank would help in the conversion of  the Jews, Frank and his followers were baptized in Poland. In 1760 he  was imprisoned by the Inquisition, who had realized that Frank�s follow�  ers regarded Frank, not Jesus, as the messiah. Freed in 1773 by invading  Russians, he settled in Germany and lived as a baron until his death.</p><p>Frank, Robert (b. Nov. 9, 1924, Zurich, Switz.) Swiss-born U.S. pho�  tographer. In the 1940s he worked as a fashion photographer for Harp�  er�s Bazaar in Paris. He abandoned fashion work in 1947 to travel in the  U.S. and South America and explore the use of the 35-mm camera. His  collection The Americans (1959), with its gritty, discordant images of  1950s America, had enormous influence and established him as a major  figure. After 1959 Frank turned to filmmaking; his short film Pull My  Daisy (1959), a collaboration with Jack Kerouac, became an underground  classic. A major later collection is Robert Frank: Moving Out (1994).</p><p>Frankel, Zacharias (b. Sept. 30, 1801, Prague, Bohemia�d. Feb. 13,  1875, Breslau, Ger.) Hungarian German rabbi and theologian. He gradu�  ated from the University of Budapest and served as rabbi in several Ger�  man communities. As chief rabbi in Dresden (1836-54), he developed a  theology called positive-historical Judaism, which diverged from Ortho�  dox Judaism in its willingness to accept scientific and historical research</p><p>as well as changes in the liturgy but adhered to traditional customs more  firmly than Reform Judaism. In 1854 he became president of Breslau�s  Jewish Theological Seminary, and his theology spread through central  Europe and to the U.S., where it took root as Conservative Judaism. His  books include Introduction to the Mishna (1859) and Introduction to the  Palestinian Talmud (1870).</p><p>Frankenthaler, Helen (b. Dec. 12, 1928, New York, N.Y., U.S.) U.S.  painter. She studied with Rufino Tamayo in high school and at Benning�  ton College, then returned to her native New York City and joined the  �second generation� of Abstract Expressionists. Influenced by Jackson Pol�  lock and Arshile Gorky, she developed a style featuring abstract colour  combinations within large expanses of bare canvas. She perfected the  technique of colour staining, producing diaphanous colour by thinning the  oils and letting them soak into the unprimed canvas. In the 1960s she  began to use acrylic paints. Though abstract, many of her paintings (e.g..  Ocean Desert, 1975) evoke landscapes and are noted for their lyricism.  Her work influenced the colour-field painters Morris Louis and Kenneth  Noland. She was married to Robert Motherwell from 1958 to 1971.</p><p>Frankfort Vfraqk-fortA City (pop., 2000: 27,741), capital of Kentucky,  U.S. Located on the Kentucky River, it was founded in 1786 and has been  the capital since statehood (1792). Twice during its early history the capi-  tol was burned, and both times the larger cities of Louisville and Lexington  tried to become the state capital. Frankfort was retained, however, because  of its central location. It is a trading centre for the Bluegrass region, pro�  ducing tobacco, com, and Thoroughbred horses, and the site of Kentucky  State University (1886).</p><p>Frankfurt (am Main) City (pop., 2002 est.: city, 641,076; metro, area,  1,896,741), western Germany. Located on the Main River, it was the site  of a Roman military settlement in the 1st century ad. It served as a royal  residence of the Carolingians from the 9th century through the Middle  Ages. A free imperial city (1372-1806), it lost its status under Napoleon  but regained it in 1815. It was the capital of Germany from 1816 until it  was annexed by Prussia in 1866. Its Old Town, once the largest surviving  medieval city in Germany, was mostly destroyed in World War II; some  landmarks survive, including its red sandstone cathedral, dedicated in  1239. International trade fairs have been held in Frankfurt since 1240; in  the modern era, book, automobile, and computer fairs are popular annual  events. The city�s manufactures include machinery and printing materi�  als, as well as the high-quality sausages known as frankfurters. Frankfurt  is the birthplace of Johann Wolfgang von Goethe.</p><p>Frankfurt National Assembly officially German National  Assembly (1848-49) German national parliament that tried and failed to  create a united German state during the liberal Revolutions of 1848. Meet�  ing in Frankfurt am Main, it proposed a constitution that provided for uni�  versal suffrage and a parliamentary government, with a hereditary emperor.  The assembly offered the crown to Frederick William IV of Prussia, but he  was too conservative to receive a German imperial crown from any hands  but those of the other German princes, and he refused. Lacking support  from either Prussia or Austria, the assembly was forced to disband.</p><p>Frankfurt school Group of thinkers associated with the Institut fur  Sozialforschung (Institute for Social Research), founded in Frankfurt in  1923 by Felix J.

After the Nazi seizure of  power in 1933, Horkheimer moved the institute to Columbia University  in New York City, where it functioned until 1941; it was reestablished in  Frankfurt in 1950. Though the institute was originally conceived as a cen�  tre for neo-Marxian social research, there is no doctrine common to all  members of the Frankfurt school. Intellectually, the school is most  indebted to the writings of G.W.F.

He pro�  moted Zionism in the U.S. and helped  found the American Civil Liberties  Union; his friend Louis Brandeis  secretly encouraged his attacks on  the Sacco-Vanzetti conviction. In  1939 he was appointed by Roosevelt  to the Supreme Court of the United  States, on which he served until 1962. He became a leading exponent of  judicial restraint, holding that judges should adhere closely to precedent  and largely disregard their personal views; his opinions evince a concern  with the integrity of government, sometimes at the expense of individual  liberties.</p><p>frankincense Fragrant gum resin obtained from trees of the genus  Boswellia (family Burseraceae), particularly several varieties found in  Somalia, Yemen, and Oman.

He sent Robert Schumann a set of  songs, which Schumann had published in 1843 without consulting Franz.  Franz Liszt became another influential supporter and published his own  book about Franz in 1872. By 1867 Franz had become almost completely  deaf and was obliged to relinquish his posts, including his professorship  at the University of Halle.

He taught himself to write effectively, and in 1723 he moved to Philadel�  phia, where he founded the Pennsylvania Gazette (1730�48) and wrote  Poor Richard�s Almanack (1732-57), whose proverbs and aphorisms  emphasized prudence, industry, and honesty. He became prosperous and  promoted public services in Philadelphia, including a library, a fire depart�  ment, a hospital, an insurance company, and an academy that became the  University of Pennsylvania. His inventions included the Franklin stove and  bifocal spectacles, and his experiments in electricity led to the invention  of the lightning rod. He served as a member of the colonial legislature  (1736�51). He was a delegate to the Albany Congress (1754). He repre�  sented the colony in England in a dispute over land and taxes (1757-62);  he returned there in 1764 as agent for several colonies. The issue of taxa�  tion gradually caused him to abandon his initial support for a unified  colonial government under British rule. Believing that taxation ought to  be the prerogative of the representative legislatures, he opposed the Stamp  Act and helped secure its repeal. He served as a delegate to the second  Continental Congress and as a member of the committee to draft the Dec�  laration of Independence. In 1776 he went to France to seek aid for the  American Revolution. Lionized by the French, he negotiated a treaty that  provided loans and military support for the U.S. In 1781 he helped nego�  tiate a preliminary peace treaty with Britain. As a member of the 1787  Constitutional Convention, he was instrumental in achieving adoption of</p><p>Franz Josef Land Russian Zemlya Frantsa-losifa</p><p>Nzim-'lya-'frants-so-'yo-so-foX Archipelago, northeastern Barents Sea.

In The Golden Bough (1890; enlarged to 12 vols., 1911�  15), Frazer examined the evolution of modes of thought from the magi�  cal to the religious and, finally, to the scientific. Although his evolutionary  sequence is no longer accepted, Frazer�s synthesis of the new science of  cultural anthropology with traditional humanistic concerns and his lively  descriptions of exotic cultural beliefs and practices had a wide influence.

The murder set off a 40-year feud with  the family of his half brother Sigebert I, whose assassination Fredegund  ordered in 575. Known for her ruthlessness and appetite for intrigue, she  also made attempts on the lives of his widow and son. After Chilperic  was murdered (584), possibly at her order, she took his riches and fled to  Paris, where she lived until her death.

June 10, 1190, Kingdom of Armenia)  Duke of Swabia (1147-90), German king (1152-90), and Holy Roman  Emperor (1155-90). He signed the Treaty of Constance (1153), which  promised him the imperial crown in return for his allegiance to the papacy.  In 1154 he launched the first of six military campaigns against northern  Italy and suppressed a revolt in Rome that restored the pope who crowned  Frederick emperor in 1155. His support for a series of antipopes against  Alexander III led to his excommunication in 1160 and a prolonged struggle  with Rome. Renewed expeditions against Italy met with opposition from  the Lombard League, which inflicted a severe defeat on Frederick in 1176.  In the Peace of Venice (1177) he acknowledged Alexander III as the true  pope, and a treaty with the Lombards was confirmed in 1183. Frederick  conquered Liibeck in 1180 and broke the power of his chief rival, Duke  Henry the Lion. He strengthened the feudal system and curbed the power  of the princes by creating a stronger imperial administration. He launched  the Third Crusade in 1189 but drowned while crossing a river.</p><p>Frederick I German Friedrich Vfre-.drikN (b. July 11, 1657, Konigs-  berg, Prussia�d. Feb. 25, 1713, Berlin, Ger.) King of Prussia (1701-13).  In 1688 he succeeded his father, Frederick William, as elector of Branden�  burg (as Frederick III). In European politics, Frederick allied himself with  Austria, England, and Holland against France. Prussia�s contingents in  the imperial army distinguished themselves in the wars of the Grand Alli�  ance and in the War of the Spanish Succession. Austria and Prussia signed  a secret treaty that permitted Frederick to crown himself king of Prussia,  which was obliged to support Austria militarily and in imperial affairs. As  a monarchy, Prussia�s diverse Hohenzollern lands were turned into prov�  inces, and Frederick freed the new kingdom from imperial control and  increased its revenues.</p><p>Frederick II German Friedrich (b. Dec. 26, 1194, Jesi, Ancona, Papal  States�d. Dec. 13, 1250, Castel Fiorentino, Apulia, Kingdom of Sicily)  King of Sicily (1197-1250), duke of Swabia (1228-35), German king  (1212-50), and Holy Roman Emperor (1220-50). The grandson of Fre�  derick I Barbarossa, he became king of Sicily at age three but did not gain  control over the strife-ridden country until 1212. He defeated his rival  Otto IV in 1214, and though the planned union of Sicily and Germany  alarmed the pope (1220), he negotiated a compromise and was crowned  emperor. A delay in departing for the Sixth Crusade brought excommu�  nication (1227), later revoked. By 1229 Frederick was king of Jerusalem.  On his return he quelled a rebellion in Germany led by his son Henry,  who had allied with the Lombard League. Seeing Frederick as a growing  threat to papal authority, Gregory IX excommunicated him again in 1239;  the emperor responded by invading the Papal States. He tried and failed  (1245) to negotiate peace with Innocent IV, and his struggle with the  papacy continued. By the time of his death Frederick had lost much of  central Italy, and his support in Germany was uncertain.</p><p>Frederick II German Friedrich known as Frederick the Great (b.</p><p>Jan. 24, 1712, Berlin�d.

On his father�s death (1740), Frederick became king and</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Frederick III &#x25BA; free energy I 707</p><p>asserted his leadership. He seized parts of Silesia during the War of the Aus�  trian Succession, strengthening Prussia considerably. He invaded Saxony in  1756 and marched on into Bohemia. Frederick was almost defeated in the  Seven Years' War (1756-63), until his admirer Peter III signed a Russo-  Prussian peace treaty that lasted until 1780. The First Partition of Poland in  1772 led to enormous territorial gains for Prussia. Austro-Prussian rivalry  led to the War of the Bavarian Succession (1778-79), a diplomatic victory  for Frederick, but continued fear of Habsburg ambitions led him to form a  league of German states against Joseph II. Under Frederick�s leadership  Prussia became one of the great states of Europe, with vastly expanded ter�  ritories and impressive military strength. In addition to modernizing the  army, Frederick also espoused the ideas of enlightened despotism and insti�  tuted numerous economic, civil, and social reforms.</p><p>Frederick III German Friedrich (b. Sept. 21, 1415, Innsbruck,  Austria�d. Aug. 19, 1493, Linz) Holy Roman emperor from 1452 and  king of Germany (as Frederick IV) from 1440. By 1439 he was the senior  member of the Habsburg dynasty, and he united the Austrian holdings of  two rival branches of the dynasty (partitioned in 1379), helping to lay the  foundations for the greatness of the house of Habsburg in European  affairs. His greatest achievement was marrying his son Maximilian (later  Maximilian I) to Mary, daughter of Charles the Bold, which gave the house  of Habsburg a large part of Burgundy and made the Austrians a European  power. Frederick was the last emperor to be crowned in Rome by a pope.</p><p>Frederick V German Friedrich known as Frederick the Winter  King (b. Aug. 26, 1596, Amberg, Upper Palatinate�d.

The Protestant Bohemian estates  revolted against the Catholic emperor Ferdinand II and offered the crown  to Frederick (1619), making him head of the Protestant union against  Catholic Austria at the beginning of the Thirty Years' War. He was soon  abandoned by his allies and was routed in the Battle of White Mountain.  In 1622 he went into exile in Holland. In 1623 he was deprived of his  rights as an elector, and in 1628 the Upper Palatinate was annexed by  Bavaria.</p><p>Frederick VII Danish Frederik Vfrith-rik\ (b.

At his accession to the elec�  torship, Brandenburg was ravaged by war and occupied by foreign troops.  He cautiously maintained neutrality between the warring Swedes and  Habsburgs, started to build a standing army, and added to his territories  with the Peace of Westphalia (1648). In the First Northern War (1655�  60) he gained sovereignty over the duchy of Prussia. In the complex power  struggles in Europe starting in 1661, he shifted allegiance by always join�  ing with the weaker party, hoping to maintain the balance of power. He  issued the Edict of Potsdam in 1685, granting asylum to Huguenots  expelled from France. When he died, he left a centralized political admin�  istration, sound finances, and an efficient army, laying the foundation for  the future Prussian monarchy.</p><p>Frederick William I German Friedrich Wilhelm (b.

Realizing that Prussia�s military and finan�  cial weakness made it dependent on the relations between the great pow�  ers, he built up an army that became a strong military presence on the  Continent, instituted economic and financial reforms, centralized his  administration, encouraged industry and manufacture, mandated compul�  sory primary education (1717), and freed the serfs on his own domains  (1719). He was succeeded by his son, Frederick II.</p><p>Frederick William II German Friedrich Wilhelm (b. Sept. 25,  1744, Berlin, Prussia�d. Nov. 16, 1797, Berlin) King of Prussia from  1786. He succeeded his uncle Frederick II. Prussia expanded under his rule,  adding territories it gained in the second (1793) and third (1795) parti�  tions of Poland and acquiring additional German lands. He entered into  an Austro-Prussian alliance, chiefly in opposition to the French Revolu�  tion, but signed a separate treaty with France and withdrew from the alli�  ance in 1795 after defeat in the French Revolutionary Wars. Cultural  activities, especially music, flourished in his reign; both Wolfgang Ama�  deus Mozart and Ludwig van Beethoven visited the king and dedicated  music to him.</p><p>Frederick William III German Friedrich Wilhelm (b. Aug. 3,  1770, Potsdam, Prussia�d. June 7, 1840, Berlin) King of Prussia (1797�  1840). The son of Frederick William II, he pursued a policy of neutrality in  the early years of the Napoleonic Wars, which accelerated the decline of  Prussia�s prestige. Prussia joined the third coalition against France in 1806  and suffered crushing defeat at the Battles of Jena and Auerstedt. Defeat  convinced the king of the need to make decisive changes. He allowed  Prussian statesmen such as Karl August, prince von Hardenberg, and Karl,  imperial baron vom Stein, to make domestic reforms, though the state  remained absolutist. The Congress of Vienna confirmed Prussia�s acqui�  sition of Westphalia and much of Saxony, but the last 25 years of the  king�s reign brought a downward trend in Prussia�s fortunes.</p><p>Frederick William IV German Friedrich Wilhelm (b. Oct. 15,  1795, Colin, near Berlin, Prussia�d. Jan. 2, 1861, Potsdam) King of  Prussia (1840-61). The son of Frederick William III, he was a disciple of  the German Romantic movement and an artistic dilettante, but his con�  servative policies helped spark the Revolutions of 1848, in opposition. In  1849 he refused the imperial crown offered by the Frankfurt National  Assembly. His subsequent efforts to create a German union under Prussian  leadership were thwarted by Austria (see Punctation of OlmOtz). A stroke  left him paralyzed in 1857, and his brother, the future William I, became  regent in 1858.</p><p>Fredericksburg, Battle of (Dec. 13,1862) Engagement of the Ameri�  can Civil War fought at Fredericksburg, Va., that resulted in a decisive  victory for the Confederate forces. Over 120,000 Union troops under  Ambrose E. Burnside were met at Fredericksburg by an entrenched Con�  federate force of 78,000 under Robert E. Lee. The Union attack failed,  resulting in more than 12,500 casualties compared to 5,000 for the Con�  federates. Burnside was relieved of his command, and the victory restored  Confederate morale lost after the defeat in the Battle of Antietam.</p><p>Fredericton City (pop., 2001: 47,560), capital of New Brunswick,  Canada Located on the St. John River and originally the site of a French  fort (1692), Fredericton was laid out as the provincial capital in 1785.  Across the river, the village of St. Anne�s Point had been settled by the  French c. 1740. After 1825 Fredericton became a British garrison town,  and its reconstructed military compound is a federal historic site.

Most molecules contain even numbers of electrons, and their  covalent bonds normally consist of shared electron pairs. Cleavage of such  bonds produces two separate free radicals, each with an unpaired electron  (in addition to any paired electrons). They may be electrically charged or  neutral and are highly reactive and usually short-lived. They combine with  one another or with atoms that have unpaired electrons. In reactions with  intact molecules, they abstract a part to complete their own electronic  structure, generating new radicals that go on to react with other molecules.  Such chain reactions are particularly important in decomposition of sub�  stances at high temperatures and in polymerization. In the human body,  oxidized (see oxidation-reduction) free radicals can damage tissues. Anti�  oxidant nutrients (e.g., vitamin C, vitamin E, selenium) may reduce these  effects. Heat, ultraviolet radiation, and ionizing radiation (see radiation  injury) all generate free radicals. They are magnetic, so their properties  can be studied with such techniques as magnetic susceptibility and elec�  tron paramagnetic resonance measurements.</p><p>Free Silver Movement Late-19th-century U.S. political movement  that advocated unlimited coinage of silver. Proponents included owners of  western silver mines, farmers who wanted higher crop prices, and debtors  who believed an expanded currency would allow them easier payment. A  depression in the mid-1870s led to an 1878 law requiring the U.S. Trea�  sury to purchase millions of dollars in silver and coin it. After farm prices  rose briefly, farm and land prices collapsed in 1887, reviving the demand  of farmers for free silver. In 1890 Congress again increased silver pur�  chases, and free silver was an objective of the Populist Movement in the  1892 election. In 1893 the amount of gold in the treasury dropped sharply,  precipitating a panic. Congress repealed the act of 1890, angering farmers.  In 1896 the Democrats nominated William Jennings Bryan for president  and backed free silver. The Republican William McKinley narrowly won. In  1900 a Republican Congress enacted the Gold Standard Act.</p><p>Free-Soil Party Minor but influential 19th-century U.S. political party  that opposed the extension of slavery into the western territories. In 1846  proponents of the Wilmot Proviso and other antislavery factions formed a  party; in 1848 it nominated former president Martin Van Buren to head its  ticket. Though Van Buren lost, many party supporters were elected to the  U.S. House of Representatives. By 1854 the party was absorbed into the  Republican Party.</p><p>Free State See Orange Free State</p><p>free-tailed bat Any of about 90 species of bats (family Molossidae),  found worldwide in warm regions, that are named for the way part of the  tail extends beyond the membrane attached between the hind legs. Also  known as mastiff or bulldog bats because of their facial resemblance to  those dogs, free-tailed bats are swift fliers with a stout body and long,</p><p>slender wings. They are about 1.6-5 in. (4-13 cm) long, excluding the  0.6-3-in. (1.5-8-cm) tail, and typically have small eyes, a heavy snout,  large ears, and dark fur. They eat insects and roost in tree hollows, caves,  and buildings. Most species live in groups; some, including the Mexican  free-tailed bat, form colonies of several million. In the past, guano from  such colonies was mined for fertilizer and for sodium nitrate (used to  make gunpowder).</p><p>free trade Policy in which a government does not discriminate against  imports or interfere with exports. A free-trade policy does not necessar�  ily imply that the government abandons all control and taxation of imports  and exports, but rather that it refrains from actions specifically designed  to hinder international trade, such as tariff barriers, currency restrictions,  and import quotas. The theoretical case for free trade is based on Adam  Smith�s argument that the division of labour among countries leads to spe�  cialization, greater efficiency, and higher aggregate production. The way  to foster such a division of labour. Smith believed, is to allow nations to  make and sell whatever products can compete successfully in an interna�  tional market.</p><p>free-trade zone Area within which goods may be landed, handled,  and re-exported freely. The purpose is to remove obstacles to trade and  to permit quick turnaround of ships and planes. Only when the goods are  moved to consumers within the country in which the zone is located do  they become subject to tariffs and customs regulation. Free-trade zones  are found around major seaports, international airports, and national fron�  tiers; there are more than 200 such zones in the U.S. alone.</p><p>free verse Poetry organized according to the cadences of speech and  image patterns rather than according to a regular metrical scheme. Its  rhythms are based on patterned elements such as sounds, words, phrases,  sentences, and paragraphs, rather than on the traditional units of metrical  feet (see metrical foot). Free verse thus eliminates much of the artifici�  ality and some of the aesthetic distance of poetic expression. It became  current in English poetics in the early 20th century. See also prosody.</p><p>free will problem Problem arising from the apparent inconsistency  between causal determinism in nature and the human power or capacity to  choose among alternatives or act freely in certain situations, thus inde�  pendently of natural, social, or divine compulsions. Its significance  derives from the fact that free will is generally considered a necessary  presupposition of moral responsibility, while determinism has (at least  until the advent of quantum mechanics) been regarded a necessary presup�  position of natural science. Arguments for free will are based on the sub�  jective experience of freedom, on sentiments of guilt, on revealed religion,  and on the supposition of responsibility for personal actions that under�  lies the concepts of law, reward, punishment, and incentive. In theology,  the existence of free will must be reconciled with God�s foreknowledge,  with divine omniscience and goodness (in allowing humans to choose  badly), and with divine grace, which allegedly is necessary for any meri�  torious act.</p><p>Freed, Arthur orig.

MGM hired him in 1929 to write lyrics for musicals, and over the  next decade he produced hits such as �Singin� in the Rain,� �Temptation,�  and �You Are My Lucky Star.� After serving as associate producer of The  Wizard ofOz (1939), he was promoted to producer. He was largely respon�  sible for the high quality of MGM�s musicals of the 1940s and �50s,  including Meet Me in St. Louis (1944), Easter Parade (1948), An Ameri�  can in Paris (1951, Academy Award), Singin� in the Rain (1952), and  Gigi (1958, Academy Award).</p><p>Freedmen's Bureau (1865-72) U.S. agency established during  Reconstruction to help freed slaves in their transition to freedom. Offi�  cially named the U.S. Bureau of Refugees, Freedmen, and Abandoned  Lands, it was directed by Oliver O. Howard. It built hospitals and pro�  vided medical assistance to more than 1 million freed blacks and 21 mil�  lion rations for blacks and whites. It also built more than 1,000 schools  for black children and helped found colleges and teacher-training insti�  tutes for blacks, but it had little success in safeguarding civil rights and  promoting land redistribution. Congress later responded to pressure from  white Southerners by terminating the bureau.</p><p>freedom of speech Right, as stated in the 1st and 14th Amendments  to the Constitution of the United States, to express information, ideas, and</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>freehold &#x25BA; Fremont I 709</p><p>opinions free of government restrictions based on content. A modern legal  test of the legitimacy of proposed restrictions on freedom of speech was  stated in the opinion by Oliver Wendell Holmes, Jr. in Schenk v. U.S.  (1919): a restriction is legitimate only if the speech in question poses a  �clear and present danger��i.e., a risk or threat to safety or to other pub�  lic interests that is serious and imminent. Many cases involving freedom  of speech and of the press also have concerned defamation, obscenity, and  prior restraint (see Pentagon Papers). See also censorship.</p><p>freehold In Anglo-American law, ownership of a substantial interest in  real property (see real and personal property) held for an indefinite period.  The term originally designated the owner of an estate held in free tenure,  who possessed, under the Magna Carta, the rights of a free man. Today  a freehold is distinguished from a leasehold, a contract to hold real prop�  erty for a specified period. See also copyhold, fee, landlord and tenant.</p><p>Freemasonry Teachings and practices of the fraternal order of Free  and Accepted Masons, the largest worldwide secret society. Originating  with the guilds of medieval stonemasons, the organization became an  honorary society in the 17th and 18 th century, adopting the rites and trap�  pings of ancient religious orders and chivalric brotherhoods. The first  association of lodges, the Grand Lodge, was founded in England in 1717,  and Freemasonry soon spread to other countries in the British Empire.  Freemasons took an active role in the American Revolution and later in  U.S. politics, and in the 19th century popular fears of their influence led  to the Anti-Masonic movement. Membership is extended only to adult  males willing to express belief in a Supreme Being and the immortality  of the soul. In Latin countries, the lodges have often attracted freethink�  ers and anticlerical types; in Anglo-Saxon nations, membership has  mostly been drawn from white Protestants. Freemasonry has also given  rise to social organizations such as the Ancient Arabic Order of the Noble  Mystic Shrine, or Shriners.</p><p>freesia Vfre-zhoV Any of the approximately 20 species of South Afri�  can plants that make up the genus Freesia, in the iris family, with corms,  grassy foliage, and wiry spikes of bell-like, lemon-scented flowers in  white, yellow, orange, and blue. The flower spikes usually turn at right  angles from the stem, displaying the flowers in a horizontal line. Two spe�  cies much used in hybridization are F. refracta, greenish-yellow to yel�  low or white, and F. armstrongii, tinged rose-purple. The plants are grown  indoors in pots or in gardens in mild climates.</p><p>Freetown Capital (pop., 1999 est.: metro, area: 822,000) and largest  city of Sierra Leone. Located at the mouth of the Sierra Leone River, it  has the best harbour in western Africa. It was founded in 1787 by an  English abolitionist, Granville Sharp, as a haven for freed African slaves  from England. Later more freed slaves from Nova Scotia and runaway  slaves from Jamaica settled there. Their descendants, known as Creoles,  are now outnumbered by Mende and Temne immigrants from the interior.  In 1821 Freetown became the seat of government for Britain�s West Afri�  can possessions. Incorporated as a municipality in 1893, it became Sierra  Leone�s capital in 1961. It is the nation�s commercial, educational, and  transportation centre. The city sustained extensive damage during the civil  war that wracked the country in the 1990s and has seen an increase in  population due to the war.</p><p>freezing Method of food preservation in which low temperatures (0 �F  [-18 �C] or lower) inhibit the growth of microorganisms. Used for cen�  turies in cold regions, it was not until the advent of mechanical refrigera�  tion in the mid 19th century that the process became widely applicable  commercially. In the 20th century, quick (or flash) freezing was devel�  oped by Clarence Birdseye. Except for beef and venison, which benefit from  an aging process, meat is frozen as promptly as possible after slaughter.  Fruits and vegetables are often frozen in a syrup or vacuum-sealed to  exclude air and prevent oxidation and desiccation.</p><p>freezing point Temperature at which a liquid becomes a solid. When  the pressure surrounding the liquid is increased, the freezing point is raised.  The addition of some solids can lower the freezing point of a liquid, a  principle used when salt is applied to melt ice on frozen surfaces. For  pure substances, the freezing point is the same as the melting point. In  mixtures and certain organic compounds, the early solid formation  changes the composition of the remaining liquid, usually steadily lower�  ing its freezing point, a principle that is applied in mixture separation.  The freezing point of pure water at standard atmospheric pressure is 32�F  (0�C). To change a liquid at its freezing point to a solid at the same tem�  perature, the heat of fusion (see latent heat) must be removed.</p><p>Frege Vfra-goV, (Friedrich Ludwig) Gottlob (b. Nov. 8, 1848, Wis-  mar, Mecklenburg-Schwerin�d. July 26, 1925, Bad Kleinen, Ger.) Ger�  man mathematician and logician, inventor of modern mathematical logic  and one of the founders of the analytic tradition in philosophy. He taught  at the University of Jena from 1871 to 1917. His Begriffsschrift (1879,  �Conceptscript�), was the first presentation of a system of mathematical  logic in the modem sense. Using an original notation of quantifiers and  variables, he was able to give formal expression to sentences containing  multiple quantification, such as �Everybody loves someone�; this is  impossible in the syllogistic derived from Aristotle, which had been con�  sidered complete until the time of Immanuel Kant (see predicate calculus).  In the Die Grundlagen der Arithmetik he attempted to establish the doc�  trine later known as logicism. He also made significant contributions to the  philosophy OF language, including a highly influential theory of the dis�  tinction between sense and reference. Though Frege�s work was admired  by Bertrand Russell and the early Ludwig Wittgenstein, it was unknown to  or ignored by most other philosophers and mathematicians during Frege�s  lifetime; its significance was not generally appreciated until the mid-20th  century.</p><p>Frei \'fra\ (Montalvo), Eduardo (b. Jan. 16, 1911, Santiago,  Chile�d. Jan. 22, 1982, Santiago) Chilean politician and president  (1964-70). He earned a law degree in 1933, held government posts in the  1940s, ran for president in 1958, and became president as a centre-left  candidate in 1964. He offered a moderate program of agrarian reform,  economic stabilization, �Chileanization� of U.S.-owned copper interests,  and a more equitable distribution of wealth. Though he made marked  progress in expanding educational opportunities for the poor, most of his  reform efforts failed to achieve their objectives, and his administration  was plagued by inflation and labour unrest. His son Eduardo Frei Ruiz-  Tagle (b. 1942) served as president from 1994 to 2000.

Chartered in 1120, Freiburg passed to the counts of Urach (later  Freiburg) in 1218. It was ruled by the Habsburgs from 1368 to 1806, when  it passed to Baden. The city was heavily bombed by the Allies during  World War II. Since rebuilt, it is now the cultural and economic centre of  the Black Forest region.

Composed of ex-soldiers and unemployed youth and led by  ex-officers, they eventually included over 65 corps of varying sizes. Most  were nationalistic and radically conservative, and they were employed  unofficially to put down left-wing revolts throughout Germany. Initially  sanctioned by the government, they came to be viewed as a nuisance and  a threat and were supplanted by regular army and police or absorbed by  new units of the Nazis and other political parties.</p><p>Freire \'fra-re\, Paulo (b.

His interactive methods, which  encouraged students to question the teacher, often led to literacy in as  little as 30 hours of instruction. In 1963 he was appointed director of the  Brazilian National Literacy Program, but he was jailed following a mili�  tary coup in 1964.

Jan. 21, 1813, Savannah,  Ga., U.S.�d. July 13, 1890, New York, N.Y.) U.S. explorer. In 1838 he  helped Joseph Nicholas Nicollet (1786-1843) survey and map the upper  Mississippi and Missouri rivers. Aided by Thomas Hart Benton, who  became his sponsor and, in 1841, his father-in-law, he led government  expeditions to map much of the area between the Mississippi River val�  ley and the Pacific Ocean. In 1845, on an expedition to California (on  which he may have carried secret instructions for action in case of war),  he supported the Bear Flag Revolt. In the Mexican War he was appointed  a major and with Robert F. Stockton helped conquer California; Stockton  later appointed him military governor of the territory. In a dispute with  Gen. Stephen Kearny he was arrested and court-martialed; though his sen�  tence of dismissal from the army was set aside by Pres. James K. Polk, he  resigned. He became wealthy in the gold rush and was elected one of  California�s first U.S. senators (1850-51). As the new Republican Party�s  presidential candidate in 1856, he was defeated by James Buchanan. In the  1870s he embarked on railroad ventures and lost his fortune.

He produced his first  important commission for the town of Concord, Mass.�the famous statue  The Minute Man (1874). He was the leading turn-of-the-century Ameri�  can sculptor, with studios in Boston, Concord, Washington, D.C., and  New York City. His best-known work, the seated marble figure of Abra�  ham Lincoln in the Lincoln Memorial, Washington, D.C., was dedicated  in 1922. His other notable public monuments include the equestrian stat�  ues of Ulysses S.

He was appointed inspector general in  1907 and chief of the army general staff in 1913. As commander of the  British Expeditionary Force from the beginning of World War I, he was  criticized for his indecisive leadership at Ypres, Belg., and elsewhere that  caused large numbers of British casualties. Forced to resign in 1915, he  served as commander in chief in Britain and later as lord lieutenant of  Ireland (1918-21).</p><p>French and Indian War North American phase of a war between  France and Britain to control colonial territory (1754-63). The war�s more  complex European phase was the Seven Years' War. Earlier phases of the  quest for overseas mastery were King William's War (1689-97), Queen  Anne's War (1702-13), and King George's War (1744-48). The North  American dispute was whether the upper Ohio River valley was a part of  the British empire or part of the French Empire; the bigger question was  which national culture would dominate the heart of North America. Brit�  ish settlers were the majority in the coveted area, but French exploration,  trade, and Indian alliances predominated. In 1754 the French ousted a  British force, including a colonial militia under Col. George Washington,  at Fort Necessity, Pa. Until 1757 the French continued to dominate, but  in 1758 Britain increased aid to its troops and won victories at Louis-  bourg, Fort Frontenac, and Fort Duquesne (Pittsburgh). The final British  victory at the Battle of Quebec (1759) led to the fall of New France (1760).  In the Treaty of Paris (1763) France ceded its North American territory  to Britain.</p><p>French Broad River River, western North Carolina, U.S. Rising in  the Blue Ridge and flowing 210 mi (340 km) north through the Great Smoky  Mountains into Tennessee, it then turns west to join the Holston River  near Knoxville, forming the Tennessee River.

It was founded in 1920 by the left wing of the French  Socialist Party but did not gain significant influence until it affliliated with  Leon Blum�s Popular Front coalition government in 1936. From 1945 to  1968 it won almost 25% of the vote in each election and had a large rep�  resentation in the National Assembly. It lost ground when Charles de  Gaulle was elected in 1958, but in 1965 it formed an alliance with other  left-wing parties. In the early 1980s it allied with the Socialist Party.

Most of French Guiana is low-lying, with mountains  in the south and a swampy coastal plain. The Maroni River forms the bor�  der with Suriname. French Guiana�s population is mostly Creole. The  principal languages are French (official) and creole; nine-tenths of the  people are Roman Catholic. Originally settled by the Spanish, French, and  Dutch, the territory of French Guiana was awarded to France in 1667, and  the inhabitants were made French citizens after 1877. By 1852 the French  began using the territory for penal settlement; the penal colony at Devils  Island was notorious. French Guiana became a department of France in  1946; the penal colonies were closed by 1953.</p><p>French Guinea See Guinea</p><p>French horn Orchestral and military brass instrument, a valved circular  horn with a wide bell. It is normally a transposing instrument (its music  written in a different tone than its actual sound) in F. It has a wide bore  and three (sometimes four) rotary valves; its conical mouthpiece produces  a mellower tone than the cup-shaped mouthpieces of other brass instru�  ments. Homs long relied on separable crooks�circular lengths of tubing  that could be attached and removed rapidly�for music modulating to new  keys. Since c. 1900 the standard horn has been a �double� instrument,  with built-in crooks in F and B-flat that can be selected rapidly by means  of a thumb valve. The modern symphony orchestra usually includes four  horns. Though difficult to play and prone to producing conspicuous errors,  its tone is widely admired.</p><p>French Indochina Former name (until 1950) for the eastern part of  mainland Southeast Asia. The region now comprises the countries of Cam�  bodia, Laos, and Vietnam. After establishing its rule by 1893, France gov�  erned it through the Indochinese Union. During World War II it was  occupied by Japan, but the French continued to administer it until the  Japanese ousted them in 1945. After the Japanese surrender, the Viet Minh  under Ho Chi Minh proclaimed the Democratic Republic of Vietnam. Laos  and Cambodia were reoccupied by the French, who founded the Indoch�  inese Federation. The First Indochina war soon erupted, and the French  ratified treaties (1949-50) that recognized Vietnam, Laos, and Cambodia  as independent states within the French Union. The area achieved full  independence from France after the Geneva Conference of 1954.</p><p>French language Romance language spoken as a first language by  about 72 million people in France, Belgium, Switzerland, Canada (mainly  Quebec), and many other countries and regions formerly governed by  France. French is an official language of more than 25 countries. Its ear�  liest written materials date from the 9th century. Numerous regional dia�  lects were eventually pushed aside by Francien, the dialect of Paris,  adopted as the standard language in the mid-16th century. This largely  replaced the dialects of northern and central France, known as the langue  d�oi'l (from oil, the northern word for �yes�), and greatly reduced the use  of the Occitan language of southern France, known as langue d�oc (from  oc, Occitan for �yes�). Regional dialects survive mostly in uneducated  rural speech. French grammar has been greatly simplified from Latin.  Nouns do not have cases, and masculine and feminine gender are marked  not in the noun but in its article or adjective. The verb is conjugated for</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>French Polynesia &#x25BA; Freon I 711</p><p>three persons and for singular and plural; though spelled differently, sev�  eral of these forms are pronounced identically.</p><p>French Polynesia formerly French Oceania \,o-she-'a-ne-3\  French overseas territory (pop., 2005 est.: 255,000), south-central Pacific  Ocean.

Tahiti, in the Society group, is the largest island and the site  of the capital, Papeete. More than two-thirds of the population of French  Polynesia lives on Tahiti. The islands became French protectorates in the  1840s, and in the 1880s the French colony of Oceania was established. It  became an overseas territory of France after World War II and was granted  partial autonomy in 1977.</p><p>French republican calendar Dating system adopted in 1793 dur�  ing the French Revolution. It sought to replace the Gregorian calendar with  a scientific and rational system that avoided Christian associations. The  12 months each contained three decades (instead of weeks) of 10 days  each, and the year ended with five (six in leap years) supplementary days.  The year began with the autumnal equinox and the day on which the  National Convention had proclaimed France a republic, 1 Vendemiaire,  Year I (Sept. 22, 1792). The other autumn months were named Brumaire  and Frimaire; they were followed by the winter months Nivose, Pluviose,  and Ventose, the spring months Germinal, Floreal, and Prairial, and the  summer months Messidor, Thermidor, and Fructidor. (All the names were  derived from words for natural phenomena.) On Jan. 1, 1806, the Grego�  rian calendar was reestablished by the Napoleonic regime.</p><p>French Revolution Movement that shook France between 1787 and  1799, reaching its first climax in 1789, and ended the ancien regime. Causes  included the loss of peasant support for the feudal system, broad accep�  tance of the reformist writings of the philosophes, an expanding bourgeoi�  sie that was excluded from political power, a fiscal crisis worsened by  participation in the American Revolution, and crop failures in 1788. The  efforts of the regime in 1787 to increase taxes levied on the privileged  classes initiated a crisis. In response, Louis XVI convened the Estates-  General, made up of clergy, nobility, and the Third Estate (commoners), in  1789. Trying to pass reforms, it swore the Tennis Court Oath not to dis�  perse until France had a new constitution. The king grudgingly concurred  in the formation of the National Assembly, but rumours of an �aristocratic  conspiracy� led to the Great Fear of July 1789, and Parisians seized the  Bastille on July 14. The assembly drafted a new constitution that intro�  duced the Declaration of the Rights of Man and of the Citizen, proclaiming  liberty, equality, and fraternity. The Constitution of 1791 also established  a short-lived constitutional monarchy. The assembly nationalized church  lands to pay off the public debt and reorganized the church (see Civil Con�  stitution of the Clergy). The king tried to flee the country but was appre�  hended at Varennes. France, newly nationalistic, declared war on Austria  and Prussia in 1792, beginning the French Revolutionary Wars. Revolu�  tionaries imprisoned the royal family and massacred nobles and clergy at  the Tuileries in 1792. A new assembly, the National Convention �divided  between Girondins and the extremist Montagnards �abolished the mon�  archy and established the First Republic in September 1792. Louis XVI  was judged by the National Convention and executed for treason on Jan.  21, 1793. The Montagnards seized power and adopted radical economic  and social policies that provoked violent reactions, including the Wars of  the Vendee and citizen revolts. Opposition was broken by the Reign of Ter�  ror. Military victories in 1794 brought a change in the public mood, and  Maximilien Robespierre was overthrown in the Convention on 9 Thermidor,  year II (in 1794 in the French republican calendar), and executed the next  day (see Thermidorian Reaction). Royalists tried to seize power in Paris but  were crushed by Napoleon on 13 Vendemaire, year IV (in 1795). A new  constitution placed executive power in a Directory of five members. The  war and schisms in the Directory led to disputes that were settled by coups  d�etat, chiefly those of 18 Fructidor, Year V (in 1797), and 18-19 Bru�  maire, Year VIII (in 1799), in which Napoleon abolished the Directory and  declared himself leader of France.

After the  National Assembly established its ascendancy over Louis XVI, in 1791  Austria and Prussia called on European rulers to assist Louis in reestab�</p><p>lishing power. France declared war in 1792 and soon had occupied all of  Belgium. The First Coalition (Prussia, Spain, the United Provinces, and  Britain) was formed against France in 1793, and in response the French  declared a levy on all Frenchmen, creating a massive army. By 1795  France had defeated the allies on every front; Prussia signed a peace treaty,  and the Netherlands became the French-influenced Batavian Republic.  Napoleon took over as commander of the Italian campaign in 1796 and  by the Treaty of Campo Formio (1797) forced Austria to cede the Austrian  Netherlands and recognize the French-organized Cisalpine and Ligurian  republics in northern Italy. He then sailed an army to Egypt to conquer  the Ottoman empire, but was defeated by Britain in the Battle of the Nile  (1798). Meanwhile, other French forces had occupied new territories and  established republican regimes in Rome, Switzerland (the Helvetic  Republic), and Italy (the Parthenopean Republic). The Second Coalition,  comprising Britain, Russia, the Ottoman empire, Naples, Portugal, and  Austria, was short-lived. By the time Napoleon became first consul of  France in 1799, the danger of foreign intervention was over. Conflict  between France and other European powers continued in the Napoleonic  Wars.</p><p>French Shore Area, coast of Newfoundland, Canada. French fisher�  men were allowed by the English to fish and to dry their catch in the region  after France gave up all other claims to Newfoundland in 1713. As defined  by the Treaty of Paris (1783), the French Shore extended west around the  island from Cape St. John in the north to Cape Ray in the southwest. In  the 1880s Newfoundland began to develop a lobster fishery, and the treaty  came under dispute. France sold its claims to the territory in 1904.</p><p>French Socialist Party originally (1905-69) French Section of  the Workers' International Political party, founded in 1905, that  supported far-reaching nationalization of the economy. Socialism in  France evolved from such 19th-century theorists as Henri de Saint-Simon,  Charles Fourier, Louis Auguste Blanqui, and Louis Blanc and from the activi�  ties of French Marxists. Led by Jean Jaures, the party grew quickly, though  it suffered a setback with the separation of the left wing into the French  Communist Party (1920). In the 1930s the French Socialist Party was cen�  tral to Leon Blum�s Popular Front government. In World War II the party  participated in the Resistance and cooperated with Charles de Gaulle,  emerging after the war as France�s second largest party. It soon lost  strength; in 1969 it won only 5% of the vote. Renamed the Socialist Party  in 1969, it was revived by Francois Mitterrand and adopted more mod�  erate policies, but it lost its dominant position in the 1990s. The 2002  elections proved disastrous for the Socialists, who won less than one-  fourth of the seats in the National Assembly.</p><p>French Somaliland See Djibouti</p><p>French Union Political entity created by the constitution of 1946 of the  Fourth Republic.

Frequency /is the reciprocal of the time T taken to com�  plete one cycle (the period), or 1 IT. The frequency with which earth rotates  is once per 24 hours. Frequency is usually expressed in units called hertz  (Hz). One hertz is equal to one cycle per second; one kilohertz (kHz) is  1,000 Hz, and one megahertz (MHz) is 1,000,000 Hz. The musical pitch  A above middle C (the A string of a violin) has been widely standardized  as 440 Hz.</p><p>frequency distribution In statistics, a graph or data set organized to  show the frequency of occurrence of each possible outcome of a repeat-  able event observed many times. Simple examples are election returns  and test scores listed by percentile. A frequency distribution can be  graphed as a histogram or pie chart. For large data sets, the stepped graph  of a histogram is often approximated by the smooth curve of a distribu�  tion function (called a density function when normalized so that the area  under the curve is 1). The famed bell curve or normal distribution is the  graph of one such function. Frequency distributions are particularly use�  ful in summarizing large data sets and assigning probabilities.</p><p>frequency modulation See FM</p><p>fresco painting Method of wall painting in which water-based pig�  ments are applied to wet, freshly laid lime plaster. The dry-powder  colours, when mixed with water, penetrate the surface and become a per�  manent part of the wall. This technique is also known as buon fresco, or  �true fresco,� to distinguish it from fresco secco, or �dry fresco� (paint�  ing on dry plaster). Early Minoan, Greek, and Roman wall paintings were  frescoes. The Italian Renaissance was the greatest period of fresco paint�  ing, as seen in the works of Cimabue, Giotto, Masaccio, Fra Angelico,  Correggio, and others. Michelangelo�s frescoes in the Sistine Chapel and  Raphael�s in the Vatican are the most famous of all. By the 18th century,  fresco had been largely replaced by oil painting. In the early 20th cen�  tury it was revived by Diego Rivera and others, often as a medium for  political art. Fresco painting is also found in China and India.</p><p>Frescobaldi \,fres-k3-'bal-de\, Girolamo (b. September 1583, Fer�  rara, Papal States�d. March 1, 1643, Rome) Italian composer and organ�  ist. In 1608 he became organist at St. Peter�s, where, except for a six-year  sojourn at the Florentine court, he would remain the rest of his life. He  was highly celebrated for both his playing and his diverse and ingenious  compositions. He wrote numerous toccatas, ricercars, and canzones for  organ and harpsichord, along with many sacred vocal works and secular  songs. His most famous work is Fiori musicali (1635), a large collection  of organ music for the mass.</p><p>Fresnel lens \fr3-'nel\ Series of concentric rings, each consisting of a  thin part of a simple lens, assembled on a flat surface. G.-L.-L. Buffon  (1748) first had the idea of dividing a lens surface into concentric rings  to reduce the weight. In 1820 his idea was adopted by Augustin-Jean  Fresnel (1788-1827) for the construction of lighthouse lenses. Fresnel  lenses have the optical properties of much thicker and heavier lenses. They  are used in spotlights, floodlights, railroad and traffic signals, and deco�  rative lights. Some thin Fresnel lenses are molded in plastic, the width of  the rings being only a few thousandths of an inch; such lenses are used  in cameras and small projectors.</p><p>Fresno Vfrez-no\ City (pop., 2000: 427,652), central California, U.S.  Located in the San Joaquin River valley, it was settled in 1872 as a sta�  tion on the Central Pacific Railroad and became an agricultural commu�  nity in the 1880s.

Austrian-born British psychiatrist, founder of the  field of child psychiatry. Daughter of Sigmund Freud, she pioneered in  developing psychoanalytic theory and practice. In The Ego and Defense  Mechanisms (1936), Freud called repression the principal human defense  mechanism. This gave a strong, new impetus to the role of ego in psy�  chology. She and her terminally ill father escaped Nazi-dominated Aus�</p><p>tria for London in 1938. She  co-wrote three books on the effects  of war on children. A summation of  her thoughts is found in Normality  and Pathology in Childhood (1968).</p><p>Freud, Lucian (b. Dec. 8, 1922,</p><p>Berlin, Ger.) German-born British  painter. Grandson of Sigmund Freud,  he moved with his family to London  when he was 10. He is known for  sombre, realistic figure paintings that  represent his subjects� raw physical  characteristics and inner tensions;  his highly individualistic, coarse  style makes no attempt to idealize its  usually nude subjects. His work has  been internationally influential in  reviving a representational style. In  1993 he was awarded the Order of  Merit.</p><p>Freud, Sigmund (b. May 6, 1856, Freiberg, Moravia, Austrian  Empire�d. Sept. 23, 1939, London, Eng.) Austrian neuropsychologist,  founder of psychoanalysis, and one of the major intellectual figures of the  20th century. Trained in Vienna as a neurologist, Freud went to Paris in  1885 to study with Jean-Martin Charcot, whose work on hysteria led  Freud to conclude that mental disorders might be caused purely by psy�  chological rather than organic factors. Returning to Vienna (1886), Freud  collaborated with the physician Josef Breuer (1842-1925) in further stud�  ies on hysteria, resulting in the development of some key psychoanalytic  concepts and techniques, including free association, the unconscious,  resistance (later defense mechanisms), and neurosis. In 1899 he published  The Interpretation of Dreams, in which he analyzed the complex sym�  bolic processes underlying dream formation: he proposed that dreams are  the disguised expression of unconscious wishes. In his controversial Three  Essays on the Theory of Sexuality (1905), he delineated the complicated  stages of psychosexual development (oral, anal, and phallic) and the for�  mation of the Oedipus complex. During World War I, he wrote papers that  clarified his understanding of the relations between the unconscious and  conscious portions of the mind and the workings of the id, ego, and  superego. Freud eventually applied his psychoanalytic insights to such  diverse phenomena as jokes and slips of the tongue, ethnographic data,  religion and mythology, and modern civilization. Works of note include  Totem and Taboo (1913), Beyond the Pleasure Principle (1920), The  Future of an Illusion (1927), and Civilization and Its Discontents (1930).  Freud fled to England when the Nazis annexed Austria in 1938; he died  shortly thereafter. Despite the relentless and often compelling challenges  mounted against virtually all of his ideas, both in his lifetime and after,  Freud has remained one of the most influential figures in contemporary  thought.</p><p>Freyberg Vfri-.borgN (of Wellington and of Munstead), Ber�  nard Cyril Freyberg, 1st Baron (b.

Most friction, though, is undesirable opposition to  motion, such as between moving parts of machines. For example, about  20% of the work done by an automobile engine is needed to overcome  friction between moving parts. Friction is a result of attractive forces  between the contact regions of two bodies, and the amount of friction is  almost independent of the area of contact. Kinetic friction arises between  surfaces in relative motion, static friction acts between surfaces at rest  with respect to each other, and rolling friction occurs when an object rolls  over a surface.</p><p>Friedan \fri-'dan\, Betty orig.

Friendly societies arose in 17th- and 18th-century Europe and  England and became most numerous in the 19th century. They trace their  roots to the burial societies of Greek and Roman artisans and the guilds  of medieval Europe. In attempting to define the magnitude of the risk  against which they guarded and to determine how much members should  contribute to meet that risk, friendly societies used what is now the basic  principle of insurance.</p><p>Friends, Sociefy of known as Quakers Protestant denomination  that arose in England in the mid-17th century. The movement began with  radical English Puritans called Seekers, who rejected the Anglican church  and other existing Protestant sects. They took their faith from itinerant  preachers such as George Fox, who emphasized �inward light,� or inward  apprehension of God, as the source of religious authority. Quaker meet�  ings are characterized by patient silence in which members wait for inspi�  ration to speak. The movement grew rapidly after 1650 (when a judge  gave them their name because �we bid them tremble at the word of God�),  but its members were often persecuted or imprisoned for rejecting the state  church and refusing to pay tithes or swear oaths. Some emigrated to  America, where they were persecuted in Massachusetts Bay Colony but  found toleration in Rhode Island and in the Quaker colony of Pennsyl�  vania, which was chartered by Charles II under the sponsorship of Wil�  liam Penn in 1681. Other marks that became characteristic of Quakerism  were plain speech and dress, pacifism, and opposition to slavery. The  group also emphasizes philanthropy, especially aid to refugees and fam�  ine victims; the American Friends Service Committee and (British)  Friends Service Council shared the 1947 Nobel Peace Prize.</p><p>Fries's Rebellion Vfrez\ (1799) Uprising, in opposition to a federal  property tax, by farmers in eastern Pennsylvania. To raise money for an  anticipated war with France, in 1798 the U.S. Congress voted a direct tax  on real property. The tax was widely resented, and an armed group of  German farmers, led by John Fries (c. 1750-1818), forced the release of  tax resisters held by federal marshals. Pres. John Adams sent federal troops  to arrest the rebels, who were tried for treason. Fries was convicted and  sentenced to be hanged, but Adams pardoned him in 1800.</p><p>frieze Yfrez\ Any long, narrow, horizontal panel or ornamental band  used for decorative purposes around the walls of a room or exterior walls  of a building.

They extend 3  to 20 mi (5 to 32 km) off the northern European mainland, along the Dutch  and German coasts and the southern part of Denmark�s Jutland peninsula.  Although they form a single physical feature, it is customary to subdivide  them into the West Frisian Islands (held by The Netherlands), East Fri�  sian Islands (Germany), and North Frisian Islands (Germany and Den�  mark). After the North Sea established a southwestern outlet to the  Atlantic about 7,000-5,000 bc, its southeasterly shore probably coincided  with the present curve of the Frisians. Periodic subsidence, storms, and  flooding have since produced this long chain of islands separated from  the mainland by a narrow belt of shallow waters and tidal mud flats. The  Dutch and German governments have spent large sums to protect the  islands� seaward coasts and reclaim the land for farming.

He had several hits  over the next two years, including �Always Late (with Your Kisses),� but  his last and biggest hit was �Saginaw, Michigan� (1963).</p><p>Froben \'fro-bon\, Johann or Johannes Frobenius (b. c. 1460,  Hammelburg, Franconia�d. October 1527, Basel, Switz.) German-born  Swiss scholar and printer active in Basel. His first publication was a Latin  Bible (1491). By 1515 he and three partners owned four presses, and later  seven. His contributions to printing in Basel included popularizing roman  type, introducing italic and Greek fonts, experimenting with cheaper and  smaller books, and employing talented artists, such as Hans Holbein, the  Younger, as illustrators. About 250 of his publications are known.</p><p>Frobisher, Sir Martin (b. c. 1535, Yorkshire, Eng.�d. Nov. 22, 1594,  Plymouth, Devon) English navigator and early explorer of Canada�s  northeastern coast. Searching for the Northwest Passage to the Pacific  Ocean, he crossed the Atlantic in 1576 and reached Labrador and Baffin  Island, discovering Frobisher Bay. Returning to England with reports of  possible gold mines, he obtained royal backing for further expeditions in  1577 and 1578; when he brought back nothing of value, his backing col�  lapsed. In 1585 he sailed as vice admiral of Sir Francis Drake�s expedi�  tion to the West Indies, and in 1588 he played a prominent part in the  campaign against the Spanish Armada.</p><p>Frobisher Bay Vfro-bi-shoiA Inlet of the North Atlantic Ocean.

Influenced by  the theories of Johann Heinrich Pestalozzi, he founded an infant school in  1837 that he later called the Kindergarten, or �garden of children.� He  believed in �self-activity� and play as essential factors in child education,  the teacher�s role being not to drill or indoctrinate but rather to encour�  age self-expression through play. He greatly influenced modern tech�  niques in preschool education, including the ideas of John Dewey.</p><p>frog Any of various tailless amphibians in the order Anura. The name may  be limited to any member of the family Ranidae (true frogs); more  broadly, it often distinguishes smooth-skinned, leaping anurans from</p><p>squat, warty, hopping ones (toads).</p><p>Frogs generally have protruding  eyes, strong, webbed hind feet  adapted for leaping and swimming,  and smooth, moist skin. Most are  predominantly aquatic, but some live  on land. They range in length (snout  to anus) from 0.4 to 12 in. (9.8  mm-30 cm). Though frogs have poi�  sonous skin glands, they rely on  camouflage for protection from  predators. Most eat insects and other  small arthropods or worms, but sev�  eral also eat other frogs, rodents, and  reptiles. They usually breed in fresh�  water, where they lay eggs that hatch  into tadpoles. Since 1989 researchers have become increasingly alarmed  by striking declines in frog populations worldwide, suspected to be linked  to climatic factors or a fungal disease.</p><p>frog hopper See spittlebug</p><p>Froissart\frwa-'sar\, Jean (b. 1333?, Valenciennes, Brabant�d. 1400/  01, Chimay, Hainaut) French court historian and poet.

A disciple of Sigmund Freud, Fromm joined the Frankfurt  school in the 1920s and left Nazi Germany for the U.S in 1933. Taking  issue with Freud, he came to believe in the interaction of psychology and  society and argued that psychoanalytic principles could be applied to cure  cultural ills. He taught at various institutions, including the National Uni�  versity of Mexico (1951-67) and New York University (from 1962). His  many books, which had popular as well as academic success, included  Escape from Freedom (1941), The Sane Society (1955), and The Crisis  of Psychoanalysis (1970); The Art of Loving (1956) became a durable  best-seller.</p><p>Fronde Vfro n d\, the (1648-53) Series of civil wars in France during  the minority of Louis XIV.

The  first phase, the Fronde of the Parlement (1648-49), was an attempt to  place constitutional limits on the queen regent, Anne of Austria, and her  chief minister, Jules Mazarin. Uprisings forced the government to concede  to the Parlement�s demands. The more serious second phase, the Fronde  of the Princes (1650-53), sprang from aristocratic opposition to Mazarin.  The military leader the Great Conde was arrested, causing his friends to  rebel (in the so-called first war of the princes). His supporters joined the  Parisian party (the Old Fronde) in successfully calling for Conde�s release  and Mazarin�s resignation. Conde lost his position when Anne joined with  the Old Fronde against him, precipitating the second war of the princes  (1651-53). After losses in battle, he fled. The king entered Paris in tri�  umph in 1652, followed by Mazarin in 1653. The Fronde was the last  serious challenge to the monarchy until the French Revolution.</p><p>front In meteorology, the interface or transition zone between two air  masses of different density and temperature.

Despite a record of mis-  govemment, he encouraged exploration that led to the expansion of the  French empire in Canada. He established fur-trading posts that brought  him into conflict with the Montreal fur traders and later expanded the posts  west. He engaged in disputes with the officials and clergy of New France.  The Iroquois Confederacy, which had remained on good terms with the  French until 1675, turned against the French, and the colony was left  defenseless. Louis XIV recalled Frontenac in 1682.

The term also refers to the occurrence of subfreez�  ing temperatures that affect plants and crops. Frost crystals, sometimes  called hoarfrost in the aggregate, form when water vapour in the atmo�  sphere passes into the ice-crystal phase without going through the inter�  mediate liquid phase. Frost forms under conditions that would form dew  if the temperature were above freezing. In agriculture, frost refers to the  freezing of the water in plant cells, which causes the cells to burst and  thereby destroys the plant.</p><p>Frost, Sir David (Paradine) (b.

Frost�s family moved to  New England early in his life. After stints at Dartmouth College and Har�  vard University and a difficult period as a teacher and farmer, he moved to  England and published his first collections, A Boy�s Will (1913) and North  of Boston (1914). At the outbreak of war he returned to New England. He  closely observed rural life and in his poetry endowed it with universal,  even metaphysical, meaning, using colloquial language, familiar rhythms,  and common symbols to express both its pastoral ideals and its dark com�  plexities. His collections include New Hampshire (1923, Pulitzer Prize),  Collected Poems (1930, Pulitzer Prize), A Further Range (1936, Pulitzer  Prize), and A Witness Tree (1942, Pulitzer Prize). He was unique among  American poets of the 20th century in simultaneously achieving wide</p><p>popularity and deep critical admira�  tion.

Cell damage, tissue dehy�  dration, and oxygen depletion caused  by freezing and thawing can lead to  blood-cell disruption, clotting in cap�  illaries, and gangrene. The toes, fin�  gers, ears, and nose are usually affected first, becoming cold, hard, white,  or bloodless. The lack of pain is dangerous. Core temperature should be  brought to near normal before rapid thawing in warm (under 115 �F [46  �C]) water. Toxoid booster injections are recommended. The outlook is  best when freezing is short-term, thawing is by rapid rewarming, and large  blisters extending to the end of the part develop early. Tissue that is refro�  zen after thawing must almost always be amputated. Affected parts become  more susceptible to recurrence. Frostbite is best prevented by wearing dry,  layered, loose clothing and remaining alert.

He was influenced by the Oxford Movement, which sought  a renewal of Roman Catholic practices within the Church of England, but  later broke with it. Among his historical works, which display both care�  lessness and his anti-Catholic bias, the best known is History of England  from the Fall ofWolsey to the Defeat of the Spanish Armada (1856�70),  which fundamentally altered the direction of Tudor studies. Immensely  prolific, he was attacked by reviewers but was popular with the reading  public. He later produced a biography (1882-84) of his friend Thomas  Carlyle.</p><p>Froude, William (b.

Brunel, for whom he oversaw railway construction. For the British  Admiralty he conducted experiments using scale models of ships to deter�  mine the physical laws governing full-sized ships, using a testing tank he  built at his home. The Froude number, expressed as the ratio of a vessel�s  velocity to the square root of the product of its waterline length and the  acceleration of gravity, is still used by marine architects to predict the  behaviour of ships from scale models.</p><p>Fructidor \fnBk-te-'dor,\ English Vfrsk-ti-.dorX, Coup of 1 8 (Sept. 4,  1799) Purge of conservatives during the French Directory period.

Apri�  cots, bananas, and grapes, as well as bean pods, corn grains, tomatoes,  cucumbers, and (in their shells) acorns and almonds, are all technically  fruits. Popularly, the term is restricted to the ripened ovaries that are sweet  and either succulent or pulpy. The principal botanical purpose of the fruit  is to protect and spread the seed. There are two broad categories of fruit:  fleshy and dry. Fleshy fruits include berries, such as tomatoes, oranges,  and cherries, which consist entirely of succulent tissue; aggregate fruits,  including blackberries and strawberries, which form from a single flower  with many pistils, each of which develops into fruitlets; and multiple fruits,  such as pineapples and mulberries, which develop from the mature ovaries  of an entire inflorescence. Dry fruits include the legumes, cereal grains, cap�  sules, and nuts. Fruits are important sources of dietary fiber and vitamins  (especially vitamin C). They can be eaten fresh; processed into juices,  jams, and jellies; or preserved by dehydration, canning, fermentation, and  pickling.</p><p>fruit bat Any of numerous tropical Old World bats in the family Pteropo-  didae as well as several species of herbivorous New World bats. Old  World fruit bats are widely distributed from Africa to South Asia and  Australasia. Most species rely on vision rather than on echolocation to  avoid obstacles. Some species are solitary, some gregarious; most roost  in the open in trees, though some inhabit caves, rocks, or buildings. Some  are red or yellow, and some are striped or spotted. They eat fruit or flow�  ers (including pollen and nectar). The smallest species in the family, the  long-tongued fruit bats, reach a head and body length of about 2.5 in.  (6-7 cm) and a wingspan of about 10 in. (25 cm). The same family con�  tains the largest of all bats, the flying foxes, which attain lengths up to  16 in. (40 cm) and a wingspan of 5 ft (1.5 m). New World fruit bats are  generally smaller and make use of echolocation. They are found in the  tropics, with many species belonging to the genera Artibeus and Sturnira.</p><p>fruit fly Any dipteran species of two families: large fruit flies (Try-  petidae) and small fruit flies, or vin�  egar flies (family Drosophilidae; see  drosophila).

As a curator at the Metropolitan Museum of Art (1906-  10), he discovered the work of the Post-Impressionists, and in 1910 he  introduced Post-Impressionism to Britain by organizing the first of two  highly significant exhibitions. With Clive Bell, Fry preached the importance  of �significant form� over content in the artwork.

Fuchsias are  valued for their showy pendulous flowers, tubular to bell-shaped, in  shades of red and purple to white.</p><p>fuel cell Device that converts chemical energy of a fuel directly into elec�  tricity (see electrochemistry). Fuel cells are intrinsically more efficient than  most other energy-conversion devices. Electrolytic chemical reactions  cause electrons to be released on one electrode and flow through an exter�  nal circuit to a second electrode. Whereas in batteries the electrodes are  the source of the active ingredients, which are altered and depleted dur�  ing the reaction, in fuel cells the gas or liquid fuel (often hydrogen, methyl  alcohol, hydrazine, or a simple hydrocarbon) is supplied continuously to  one electrode and oxygen or air to the other from an external source. So,  as long as fuel and oxidant are supplied, the fuel cell will not run down  or require recharging. Fuel cells can be used in place of virtually any other  source of electricity. They are especially being developed for use in elec�  tric automobiles, in the hope of achieving enormous reductions in pollu�  tion.</p><p>fuel injection In an internal-combustion engine, introduction of fuel into  the cylinders by a pump rather than by the suction created by the move-</p><p>Fruit fly (Trypetidae)</p><p>E.S.

On diesel engines, which lack  spark plugs, the heat created by compressing air in the cylinders ignites the  fuel, which has been pumped in as a spray. In engines with spark igni�  tion, fuel-injection pumps are often used instead of conventional carbu�  retors. Fuel injection distributes the fuel more evenly to the cylinders than  does a carburetor; more power can be developed and undesirable emis�  sions are reduced. In engines with continuous combustion, such as gas  turbines and liquid-fueled rockets, which have no pistons to create suction,  fuel-injection systems are necessary.</p><p>Fuentes \fu-'en-tas\, Carlos (b.

The Death of Artemio Cruz (1962), about the final hours of an unscrupu�  lous former revolutionary, made his international reputation. Among his  later novels are Terra Nostra (1975), The Hydra Head (1978), The Old  Gringo (1985), and The Years with Laura Diaz (1999). �The Buried Mir�  ror� (1992) is a long essay on Hispanic cultures.</p><p>Fugard \fii-'gard\, Athol (Harold Lannigan) (b.

He resumed the theme  in Hello and Goodbye (1965) and Boesman and Lena (1969; film, 1973,  with Fugard as Boesman). He experimented with an imagist approach to  drama in Orestes (1971) and three other works, then returned to more  traditionally structured plays. His � Master Harold�...and the Boys  (1982), The Road to Mecca (1984), and My Children! My Africa! (1989)  were acclaimed in London and New York City.

The family busi�  ness traces its origins to Hans (Johannes) Fugger (1348-1409), a weaver  in Augsburg. Under his grandsons Ulrich (1441-1510), Georg (1453�  1506), and especially Jakob (1459-1525), the company became estab�  lished in international trade, including the lucrative spice and slave trades,  and built a fortune in copper and silver mining. Their loans to various  kings and emperors and involvement with the sale of papal indulgences  made family members highly influential in European politics and earned  them the criticism of Martin Luther. The family�s influence declined after  the 16th century, but three titled lines survived into the 20th century.</p><p>Fugitive Slave Acts U.S. laws of 1793 and 1850 (repealed in 1864)  that provided for the seizure and return of runaway slaves. The 1793 law  authorized a judge alone to decide the status of an alleged fugitive slave.  Northern opposition led to enactment of state personal-liberty laws that  entitled slaves to a jury trial and as early as 1810 prompted individuals  to aid the Underground Railroad. Increased pressure from the South  brought passage of the second statute in 1850, as part of the Compromise  of 1 850. It imposed penalties on federal marshals who refused to enforce  the law and on individuals who helped slaves to escape; fugitives could  not testify on their own behalf, nor were they permitted a jury trial. Its  severity led to increased interest in the abolition movement. Additional  personal-liberty laws enacted by northern states to thwart the act were  cited by South Carolina as justification for its secession in 1860.</p><p>fugue \'fyiig\ Musical composition characterized by systematic imita�  tion of one or more themes in counterpoint. Fugues vary greatly in their  actual form. The principal theme (subject) is imitated�i.e., repeated suc�  cessively in similar form at different pitch levels by different parts or  voices�in the so-called exposition. The countersubject is the continua�  tion of the subject that accompanies the subject theme�s subsequent  entries in the other voices. Episodes using modified themes often sepa�  rate the subject�s entries. The fugue emerged gradually from the imitative  polyphony of the 13th century. Johann Sebastian Bach�s keyboard fugues  are the most famous of all. The works of Bach and George Frideric Han�  del inspired the later fugues of Wolfgang Amadeus Mozart, Ludwig van  Beethoven, and others, many of whom commonly included fugues in the  final movements of symphonies, string quartets, and sonatas.</p><p>Fuji, Mount or Fujiyama Japanese Fuji-san Mountain, central  Japan.

It is  considered a sacred symbol of Japan, and thousands of Japanese climb to  the shrine on its peak every summer. The mountain is the major feature  of Fuji-Hakone-Izu National Park, created in 1936.</p><p>Fujian \'fu-'jyen\ or Fu-chien conventional Fukien Vfii-'kyenV Prov�  ince (pop., 2002 est.: 34,660,000), southeastern China. Located on the  southeastern coast, it is bounded by the East China Sea and Taiwan Strait  and Guangdong, Jiangxi, and Zhejiang provinces. It has an area of 47,500  sq mi (123,100 sq km), and its capital is Fuzhou. The province�s bound�  aries were established during the Song dynasty (1127-1279), when it  became an important shipbuilding and commercial centre for overseas and  coastal trade. It declined when the Ming dynasty (1368-1644) banned  maritime commerce. Its coastal cities were occupied by the Japanese in  World War II, and the 3rd Field Army took control of the province in  1949. In addition to being an important agricultural region, it is an area  of special economic zones established in 1979 to attract foreign invest�  ment to China.</p><p>Fujimori \,fu-je-'m6-re\, Alberto (Kenyo) (b. July 28, 1938, Lima,  Peru) President of Peru (1990-2000). The son of Japanese immigrants, he  graduated from Agrarian National University in 1961. He first entered  politics in 1989 as the head of the new political party Cambio 90 (�Change  90�). He won a surprise victory in the 1990 presidential election and in  1992 he dissolved the National Congress and took other steps to concen�  trate power in the presidency. He claimed credit for the capture of the  leader of the Shining Path rebel movement later that year and, in 1997, the  successful storming of the Japanese ambassador�s residence in Lima,  where Tupac Amaru guerrillas had held dozens of hostages. He was  reelected in 1995 and asserted victory, despite charges of fraud, in the  2000 election, but scandal involving his secret-police chief caused him to  flee to Japan.</p><p>Fujiwara Vfu-je-'wa-ra\ family Dynastic family that dominated Japa�  nese court government in the 9th-12th centuries. The family maintained  a close relationship to the imperial family by marrying its daughters to  emperors so that their grandsons and nephews became emperors. The  Fujiwara acted as regents for child emperors and later created the post of  kampaku, or chancellor, essentially a regent for an adult emperor. Fuji�  wara Michinaga (966-1028), who  married three daughters to emperors  and a fourth to an heir apparent,  epitomized Fujiwara power and  glory; his ascendancy marked the  height of the Heian period, during  which Murasaki Shikibu wrote The  Tale ofGenji. The family�s power at  court waned after Michinaga and  was eliminated in the 12th century.</p><p>See also Sugawara Michizane.</p><p>Fujiwara style Japanese sculp�  tural style of the late Heian period  (897-1185).

Their language is  Fula, an Atlantic language of the  Niger-Congo family. Originally they  were herders, but interaction with  other groups produced marked cul�  tural changes. In the 1790s the  Fulani priest Usman dan Fodio led a  holy war (jihad) that created a large  empire. Its decay in the 19th century  aided the establishment of British  rule over northern Nigeria. Many  Fulani of northern Nigeria have  adopted the Hausa language and cul�  ture and established themselves as an  urban aristocracy.</p><p>Fulbright, J(ames) William (b.</p><p>April 9, 1905, Sumner, Mo.,</p><p>U.S.�d.

In 1942 he was  elected to the U.S. House of Representatives, where in 1943 he introduced  a resolution supporting U.S. participation in what would become the UN.  In the U.S. Senate (1945-75), he initiated the international exchange pro�  gram known as the Fulbright scholarship. As chairman of the Senate For�  eign Relations Committee (1959-74), he presided over televised hearings  in 1966 on U.S. policy in the Vietnam War, from which he emerged as a  leading advocate of ending the bombing of North Vietnam and opening  peace talks. In 1974 he lost his bid for reelection.</p><p>Fulbright scholarship Educational grant under an international  exchange program created to increase understanding between the U.S. and  other countries.

Sept. 1, 1878, Chichester,  Sussex, Eng.�d. Feb. 10, 1966, Falmouth, Cornwall) British military  theoretician and historian. He served as chief of staff of the British tank  corps in World War I. He planned the surprise attack of 381 tanks at the  Battle of Cambrai (Nov. 20, 1917), the first massed tank assault in his�  tory. After the war he launched a crusade for the mechanization and mod�  ernization of the British army. His emphasis on the armoured offensive  met with resistance among English military tacticians, but his teachings  were largely vindicated in World War II. His works include Tanks in the  Great War (1920), Machine Warfare (1942), and A Military History of the  Western World (1954-56).</p><p>Fuller, Loie orig. Marie Louise Fuller (b.

She began acting at age four,  appearing with stock companies and vaudeville shows. From 1892 in Paris  she gained attention with her �serpentine dance,� in which she used yards  of flowing silk illuminated by theatrical lighting. She added a �fire dance�</p><p>(dancing on an illuminated pane of  glass) and other acts, attracting criti�  cal and public adulation, especially  in Europe.</p><p>Fuller, (Sarah) Margaret mar�  ried name Marchesa Ossoli (b.</p><p>May 23, 1810, Cambridgeport,</p><p>Mass., U.S.�d.

She  became part of the Transcendentalist  circle (see Transcendentalism), was a  close friend of Ralph Waldo Emerson,  and eventually became the founding  editor of the Trancendentalist maga�  zine The Dial (1840-42). Her Sum�  mer on the Lakes, in 1843 (1844), a  study of frontier life, was followed  by Woman in the Nineteenth Century  (1845), a demand for women�s  political equality and a plea for  women�s intellectual and spiritual fulfillment. She traveled to Europe in  1846 as a correspondent for the New York Tribune. In Italy she married a  revolutionary marquis; forced into exile, they perished in a shipwreck  while returning to the U.S.</p><p>Fuller, Melville (Weston) (b. Feb. 11, 1833, Augusta, Me., U.S.�d.  July 4, 1910, Sorrento) U.S. jurist. After graduating from Bowdoin Col�  lege and Harvard Law School, he built a major legal practice in Chicago  (from 1856), where he became prominent in Democratic Party politics.  Although unknown nationally, he was appointed chief justice of the  Supreme Court of the United States in 1888 by Pres. Grover Cleveland; he  would remain on the Court until his death. His colleagues included Oliver  Wendell Holmes, Jr., and John Marshall Harlan. He wrote the Court�s opin�  ion in Pollock v. Farmers' Loan and Trust Co., which declared a federal  income tax unconstitutional. He also served on the Hague Court of Inter�  national Arbitration (1900-10).</p><p>Fuller, R(ichard) Buckminster (b. July 12, 1895, Milton, Mass.,  U.S.�d. July 1, 1983, Los Angeles, Calif.) U.S. inventor, futurist, archi�  tect, and author. The grandnephew of Melville Fuller, he was expelled twice  from Harvard University and never completed his college education. Fail�  ure in a prefab construction business led him to search for design patterns  that would most efficiently use Earth�s resources for humanity�s greatest  good. His innovations included the inexpensive, lightweight, factory-  assembled Dymaxion House and the energy-efficient, omnidirectional  Dymaxion Car. He developed a vectorial system of geometry that he  called �Energetic-Synergetic geometry�; its basic unit is the tetrahedron,  which, when combined with octahedrons, forms the most economic space�  filling structures. This led Fuller to design the geodesic dome, the only  large dome that can be set directly on the ground as a complete structure,  and the only practical kind of building that has no limiting dimensions  (i.e., beyond which the structural strength must be insufficient).</p><p>fullerene Any of a class of all-carbon molecules whose atoms are  arranged in closed hollow shells. Allotropes of carbon first identified in  1985, they have varying (but even) numbers of atoms bonded into struc�  tures having 12 pentagonal and 2 or more hexagonal faces. Fullerenes  comprising dozens to hundreds of carbon atoms have been prepared. The  best known and most stable fullerene, buckminsterfullerene (C 60 , nick�  named buckyball), has 60 carbon atoms arranged in a pattern like that on  a standard soccer ball. It is named for R. Buckminster Fuller, whose geo�  desic dome designs its structure resembles. Chemists have made fullerene  derivatives (e.g., with attached hydrogen or halogen atoms or organic  groups; see functional group) and have prepared doped fullerenes (e.g.,  with alkali metal atoms such as potassium; see dopant) that show supercon�  ductivity at relatively high temperatures. One or more metal or noble-gas  atoms can be trapped in the molecule�s hollow interior, resulting in unique  complexes called endohedral fullerenes.</p><p>Fullerton City (pop., 2000: 126,003), southern California, U.S. Laid out  in 1887, it developed as a citrus centre after the arrival of the Santa Fe  Railroad in 1888.

The northern fulmar (Fulmaris glacia-  lis) ranges from temperate to Arctic waters, and the southern fulmar ( F.  glacialoides ) from temperate to Antarctic waters. The much larger giant  fulmar, or giant petrel (.Macronectes giganteus), is 3 ft (90 cm) long and  has a wingspan of more than 6.5 ft (200 cm). It nests around the Antarc�  tic Circle. Fulmars eat almost anything; their natural foods are small fish,  squid, and crustaceans, but they often take ships� garbage and will come  ashore for carrion. They fly low over the waves of the open ocean, thus  resembling their narrower-winged relatives, the shearwaters, in flight.</p><p>Fulton, Robert (b. Nov. 14, 1765, Lancaster county, Pa., U.S.�d. Feb.  24, 1815, New York, N.Y.) U.S. inventor and engineer. Bom to Irish  immigrant parents, he studied painting with Benjamin West in London but  soon turned to engineering. After designing a system of inland waterways,  he tried unsuccessfully to interest the French and British governments in  his prototypes of submarines (see Nautilus) and torpedoes. In 1801 he was  commissioned by Robert R. Livingston to build a steamboat, and in 1807  Fulton�s Clermont made the 150-mi (240-km) journey up the Hudson  River from New York City to Albany in 32 hours, cutting 64 hours off  the usual sailing time. It became the first commercially successful steam�  boat in the U.S. He later designed several other steamboats, including the  world�s first steam warship (1812). He was a member of the commission  that recommended building the Erie Canal.</p><p>fumarole \ , fyu-m3- l rol\ Volcanic vent from which steam and volcanic  gases issue. The major source of the steam emitted by fumaroles is  groundwater heated by magma. Carbon dioxide, sulfur dioxide, and hydro�  gen sulfide are usually emitted directly from the magma. A fumarole rich  in sulfur gases is called a solfatara; a fumarole rich in carbon dioxide is  called a mofette.</p><p>Funafuti \,fu-na-'fu-te\ Coral atoll (pop., 2000 est.: 4,590), Tuvalu, west-  central Pacific Ocean.

Funchal was founded in 1421  by the Portuguese navigator Joao Gonsalves Zarco and later came under  Spanish (1580-1640) and British (1807-14) control. The city�s scenery  and mild year-round climate attract many tourists.</p><p>function In mathematics, an expression, rule, or law that defines a rela�  tionship between one variable (the independent variable) and another (the  dependent variable), which changes along with it. Most functions are  numerical; that is, a numerical input value is associated with a single  numerical output value. The formula A = nr 2 , for example, assigns to each  positive real number r the area A of a circle with a radius of that length.  The symbols f(x) and g(x) are typically used for functions of the inde�  pendent variable x. A multivariable function such as w = f(x, y) is a rule  for deriving a single numerical value from more than one input value. A  periodic function repeats values over fixed intervals. If f{x + k) =f{x) for  any value of x, f is a periodic function with a period of length k (a con�  stant). The trigonometric FUNCTIONS are periodic. See also density function;  EXPONENTIAL FUNCTION; HYPERBOLIC FUNCTION; INVERSE FUNCTION; TRANSCENDENTAL  FUNCTION.</p><p>functional analysis Branch of mathematical analysis dealing with  functionals, or functions of functions. It emerged as a distinct field in the  20th century, when it was realized that diverse mathematical processes,  from arithmetic to calculus procedures, exhibit very similar properties. A  functional, like a function, is a relationship between objects, but the  objects may be numbers, vectors, or functions. Groupings of such objects  are called spaces. Differentiation is an example of a functional because it  defines a relationship between a function and another function (its deriva�</p><p>tive). Integration is also a functional. Functional analysis focuses on  classes of functions, such as those that can be differentiated or integrated.</p><p>functional group In molecules, any of numerous combinations of  atoms that undergo characteristic chemical reactions themselves and in  many cases influence the reactivity of the rest of the molecule. Organic  compounds are often classified according to the functional groups they  contain. Common functional groups include hydroxyl (�OH), in alco�  hols and phenols; carboxyl (�COOH), in carboxylic acids; carbonyl</p><p>(�C=0), in ALDEHYDES, KETONES, AMIDES, CARBOXYLIC ACIDS, ESTERS, and QUINO�  NES; and nitro (�N0 2 ) and amino (�NH 2 ), in certain organic nitrogen  compounds.</p><p>functionalism In the social sciences, a theory that stresses the inter�  dependence of the patterns and institutions of a society and their interac�  tion in maintaining cultural and social unity. In sociology, functionalism  emerged from the work of Emile Durkheim, who viewed society as a kind  of �organism� that carried with it certain �needs� that must be fulfilled.  Similar views were adopted in anthropology by A.R. Radcliffe-Brown,  who attempted to explain social structures as enduring systems of adap�  tation, fusion, and integration; and by Bronislaw Malinowski, who viewed  culture as the expression of the totality of individual and collective  achievement, where �every custom, material object, idea, and belief ful�  fills some vital function.� The U.S. sociologist Talcott Parsons analyzed  large-scale societies in terms of their social, psychological, and cultural  components and focused on problems of social order, integration, and  equilibrium. Later writers argued that functionalism was too rigid to  account for the breadth, depth, and contingencies of human social life and  that it ignored the role of history in shaping society.</p><p>functionalism In psychology, a broad school of thought that originated  in the U.S. in the late 19th century and emphasized the total organism in  its endeavours to adjust to the environment. Reacting against the school  of structuralism led by Edward Bradford Titchener, functionalists such as  William James, George Herbert Mead, and John Dewey stressed the impor�  tance of empirical, rational thought over an experimental trial-and-error  philosophy. The movement concerned itself primarily with the practical  applications of research (see applied psychology) and was critical of early  forms of behaviourism.</p><p>Functionalism In architecture, the doctrine that a building�s form  should be determined by practical considerations of use, material, and  structure and not by a preconceived picture in the designer�s mind.  Though not an exclusively modern conception, it is closely associated  with the Modernist architecture of the second quarter of the 20th century.  The fight for an �honest� form of expression by architects such as Louis  Sullivan and Le Corbusier came about as a result of changes in building  techniques, needs for new types of buildings, and discontent with histori�  cal revivalism, which had been paramount in the 19th and early 20th cen�  turies.</p><p>fundamental interaction In physics, the effect of any of the four  fundamental forces�gravitational, electromagnetic, strong, and weak. All  known natural forces can be traced to these fundamental interactions.  Gravitation is the attractive force between any two objects that have mass;  it causes objects to fall to the ground and maintains the orbits of planets  around the Sun. Electromagnetic force is responsible for the attraction and  repulsion between electric charges and explains the chemical behaviour of  atoms and the properties of light. The strong force binds quarks together  in protons, neutrons, and other hadrons and also holds the protons and  neutrons of an atomic nucleus together, overcoming the repulsion of the  positively charged protons for each other. The weak force is observed in  certain forms of radioactive decay (see radioactivity) and in reactions that  fuel the Sun and other stars.</p><p>fundamental theorem of algebra Theorem of equations proved  by Carl Friedrich Gauss in 1799. It states that every polynomial equation  of degree n with complex number coefficients has n roots, or solutions, in  the complex numbers.</p><p>fundamental theorem of arithmetic Fundamental principle of  number theory proved by Carl Friedrich Gauss in 1801. It states that any  integer greater than 1 can be expressed as the product of prime numbers in  only one way.</p><p>fundamental theorem of calculus Basic principle of calculus. It  relates the derivative to the integral and provides the principal method for  evaluating definite integrals (see differential calculus; integral calculus). In</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>fundamentalism &#x25BA; furniture I 721</p><p>brief, it states that any function that is continuous (see continuity) over an  interval has an antiderivative (a function whose rate of change, or deriva�  tive, equals the function) on that interval. Further, the definite integral of  such a function over an interval a &lt; x &lt; b is the difference F(b) - F(a),  where F is an antiderivative of the function. This particularly elegant  theorem shows the inverse function relationship of the derivative and the  integral and serves as the backbone of the physical sciences. It was articu�  lated independently by Isaac Newton and Gottfried Wilhelm Leibniz.</p><p>fundamentalism, Christian Conservative Protestant movement  that arose out of 19th-century millennialism in the U.S. It emphasized as  fundamental the literal truth of the Bible, the imminent physical Second  Coming of Jesus, the virgin birth, resurrection, and atonement. It spread  in the 1880s and �90s among Protestants dismayed by labour unrest,  Catholic immigration, and biblical criticism. Scholars at Princeton Theo�  logical Seminary provided intellectual arguments, published as 12 pam�  phlets (1910-15). Displeasure over the teaching of evolution, which many  believed could not be reconciled with the Bible, and over biblical criti�  cism gave fundamentalism momentum in the 1920s. In the 1930s and  �40s, many fundamentalist Bible institutes and colleges were established,  and fundamentalist groups within some Baptist and Presbyterian denomi�  nations broke away to form new churches. In the later 20th century, fun�  damentalists made use of television as a medium for evangelizing and  became vocal in politics as the �Christian right.� See also evangelicalism;  Pentecostalism.</p><p>fundamentalism, Islamic Conservative religious movement that  seeks a return to Islamic values and Islamic law (see Sharia) in the face  of Western modernism, which is seen as corrupt and atheistic. Though  popularly associated in the West with Middle Eastern terrorists, only a  few Islamic fundamentalists are terrorists, and not all Arab terrorists are  fundamentalists. The Iranian revolution of 1979 established an Islamic  fundamentalist state, and the Taliban has established its version of the same  in much of Afghanistan. Islamic fundamentalist movements have varying  degrees of support in North Africa, Pakistan, Bangladesh, and Muslim  S.East Asia, but Islamic fundamentalism represents a minority viewpoint  in the context of world Islam.</p><p>Fundy, Bay of Inlet of the Atlantic Ocean, southeastern Canada  Located between the provinces of New Brunswick and Nova Scotia, it  extends 94 mi (151 km) inland and is 32 mi (52 km) wide at its entrance.  It is noted for its fast-running tides, which may produce rises as great as  70 ft (21 m), the highest in the world. Noted also for the spectacular rock  formations and forests of its shorelines, it has several deepwater harbours,  including one at St. John, N.B. In 1948 a 51,000-acre (20,700-hectare)  section of the bay�s New Brunswick coast was set aside as Fundy National  Park.</p><p>Funen Danish Fyn \'fuen\ Island and county (pop., 2001: 472,064) of  Denmark. It covers an an area of 1,346 sq mi (3,486 sq km), and it is  located between Sjaelland and the Jutland Peninsula. Its administrative  centre and largest city is Odense. The island is a fertile agricultural region.  Road and rail bridges and femes connect the island with the rest of Den�  mark.</p><p>fungal diseases or mycoses Diseases caused by any fungus that  invades the tissues. Superficial fungal infections (e.g., athlete�s foot) are  confined to the skin. Subcutaneous infections, which extend into tissues  and sometimes adjacent structures such as bone and organs, are rare and  often chronic. In systemic infections, fungi spread through the body of a  normal (or, more often, an immunosuppressed) host. Some fungal diseases  (e.g., yeast infections) may be either superficial or systemic, affecting cer�  tain target organs.</p><p>fungicide Vfon-jo-.sld, 'foq-go-.sIdN Any toxin used to kill or inhibit  growth of fungi (see fungus) that cause economic damage to crop or orna�  mental plants (including rusts in cereals, blight in potatoes, mildew in  fruits) or endanger the health of domestic animals or humans. Most are  applied as sprays or dusts; seed fungicides are applied as a protective coat�  ing to seeds before germination. Copper compounds, especially copper sul�  fate mixed with lime and water (Bordeaux mixture), and sulfur have long  been used for this purpose, but now synthetic organic compounds are com�  monly used. Many antifungal substances occur naturally in plant tissues.</p><p>fungus Any of about 200,000 species of organisms belonging to the  kingdom Fungi, or Mycota, including yeasts, rusts, smuts, molds, mush�  rooms, and mildews. Though formerly classified as plants, they lack chlo�</p><p>rophyll and the organized plant  structures of stems, roots, and leaves.</p><p>Fungi contribute to the disintegration  of organic matter resulting in the  release of carbon, oxygen, nitrogen,  and phosphorus from dead plants  and animals into the soil or the atmo�  sphere. Fungi can be found in the  water, soil, air, plants, and animals of  all regions of the world that have suf�  ficient moisture to enable them to  grow. Essential to many food and  industrial processes, fungi are also  used in the production of enzymes, organic acids, vitamins, and antibiotics.  They also can destroy crops, cause such diseases as athlete's foot and  ringworm, and ruin clothing and food with mildew and rot. The thallus,  or body, of a typical fungus consists of a mycelium through which cyto�  plasm flows. The mycelium generally reproduces by forming spores, either  directly or in special fruiting bodies that are generally the visible part of  the fungus. The soil provides an ideal habitat for many species. Lacking  chlorophyll, fungi are unable to carry out photosynthesis and must obtain  their carbohydrates by secreting enzymes onto the surface on which they  are growing to digest the food, which they absorb through the mycelium.  Saprophytic fungi live off dead organisms and are partly responsible for  the decomposition of organic matter. Parasitic fungi invade living organ�  isms, often causing disease and death (see parasitism). Fungi establish  symbiotic relationships with algae (forming lichens), plants (forming myc-  orrhizae; see mycorrhiza), and certain insects.</p><p>Funk, l(saac) K(auffman) (b.

He received his Ph.D. from Northwestern Univer�  sity. With Louis J. Ignarro and Ferid Murad, he found that nitric oxide acts  as a signaling molecule in the cardiovascular system. Furchgott demon�  strated that cells in the endothelium of blood vessels produce a molecule  called endothelium-derived relaxing factor (EDRF), which signals smooth  muscle cells in blood vessel walls to relax, dilating the vessels. Ignarro  later concluded that EDRF was nitric oxide. The research done by Furch�  gott, Murad, and Ignarro was key to the development of the drug Viagra,  which treats impotence. The three men shared a 1998 Nobel Prize.</p><p>Furies Group of Greco-Roman goddesses of vengeance. The Furies lived  in the underworld and ascended to earth to pursue the wicked. They were  known to the Greeks as the Erinyes, but those who feared to speak their  name often called them by euphemisms such as Eumenides (�Kind  Ones�). According to Hesiod, they were daughters of Gaea, the earth god�  dess. Aeschylus made them the terrifying chorus of his tragedy Eumenides ,  and Euripides was the first to speak of them as three in number.</p><p>furniture Household equipment designed for a variety of purposes.

His revised Te Denm (1910) established him as a composer, and in 1917  his work as a guest conductor in Berlin earned him high praise. He suc�  ceeded Richard Strauss at the Berlin State Opera, and Arthur Nikisch  (1855-1922) at the Leipzig Gewandhaus and Berlin Philharmonic,  becoming especially associated with the music of Ludwig van Beethoven  and Richard Wagner. Though criticized for staying in Germany during the  Nazi era, he was no friend of the regime, continuing to program modem  music and helping Jewish musicians to escape. He was formally exoner�  ated of complicity with the Nazis, but public hostility dogged his later  years.</p><p>fuse In electrical engineering, a safety device that protects electric circuits  from the effects of excessive electric currents.

Johann Heinrich Fussli (b. Feb.  7, 1741, Zurich, Switz.�d. April 16, 1825, London, Eng.) Swiss-born  British painter and writer on art. The son of a portrait painter, he trained  in theology as well as in art and art history. He left his native Zurich for  London in 1764. Encouraged by Sir Joshua Reynolds, he went to Italy in  1770 and stayed for eight years; on his return to England, his works  exhibited at the Royal Academy, such as his most famous work, The  Nightmare (1781), secured his reputation. His subject matter was chiefly  literary, and his images portrayed macabre fantasies and the grotesque.  He was elected a full academician in 1790 and taught painting at the  academy (1799-1805).</p><p>Fustel de Coulanges \fm-stel-d3-ku-'la n zh\, Numa Denis (b.</p><p>March 18, 1830, Paris, France�d.

He champi�  oned the importance of objectivity and the unreliability of secondary  sources, which became important tenets of modern historiography, and  his insistence on the use of contemporary documents led to the full use  of the French national archives in the 19th century. Most of his work,  including La Cite antique (1864) and La Gaule romaine (1891), dealt with  Roman Gaul and the Germanic invasions of the Roman Empire.</p><p>fusulinid N.fyu-zo-'lI-nadV Any of a large group of extinct foraminifer-  ans, single-celled organisms related to amoebas but having complex shells  that are easily preserved as fossils. The fusulinids first appeared during  the Carboniferous period, perhaps c. 320 million years ago, and persisted  until the end of the Permian period, 248 million years ago. They have been  extremely useful for correlating different rock units in widely separated  regions and for dividing geologic time into smaller units. Petroleum  geologists also use them to help locate economically valuable deposits of  oil and natural gas.</p><p>Futabatei Shimei \fu-'ta-ba-ta-'she-ma\ orig. Hasegawa Tatsun-  osuke (b.

He is best known for Ukigumo  (1887-89; �The Drifting Clouds�), his first novel, and for his translations  of stories by Ivan Turgenev. In these he used a style called gembun itchi  (�unification of spoken and written language�), one of the first attempts  at a modern colloquial idiom. His later works include the novels An  Adopted Husband (1906) and Mediocrity (1907). He is credited with  bringing modern realism to the Japanese novel.</p><p>futhark See runic writing</p><p>futures Commercial contracts calling for the purchase or sale of speci�  fied quantities of a good at specified future dates. The good in question  may be grain, livestock, precious metals, or financial instruments such as  treasury bills. Up until the time the contract calls for the delivery of the  good, the contract is subject to speculation. Futures contracts originated  in the trade in agricultural commodities; for example, American grain  farmers were able to sell their harvest in advance on the Chicago Board  of Trade, a commodity exchange.</p><p>Futurism Early 20th-century art movement, centred in Italy, that cel�  ebrated the dynamism, speed, and power of the machine and the vitality  and restlessness of modem life. The term was coined by Filippo Marinetti,  who in 1909 published a manifesto glorifying the new technology of the  automobile and the beauty of its speed and power. In 1910 Umberto Boc-  cioni and others published a manifesto on painting. They adopted the Cub�  ist technique of depicting several views of an object simultaneously with  fragmented planes and outlines and used rhythmic spatial repetitions of  the object�s outlines in transit to render movement. Their preferred sub�  jects were speeding cars and trains, racing cyclists, and urban crowds;  their palette was more vibrant than the Cubists�. With Boccioni, the most  prominent Futurist artists were his teacher, Giacomo Balia (1871-1958),  and Gino Severini (1883-1966). Boccioni�s death in 1916 and World War  I brought an end to the movement, which had a strong influence in pos�  trevolutionary Russia and on Dada.</p><p>Futurism Literary, artistic, and political movement. Futurism, which  began in Italy about 1909, was marked especially by violent rejection of  tradition and an effort to give formal expression to the dynamic energy  and movement of mechanical processes. Its most significant results were  in the visual arts and poetry. Futurism was first announced in a manifesto  by Filippo Marinetti. The principal Italian Futurist artists were Giacomo  Balia (1871-1958), Umberto Boccioni, Carlo Carra (1881-1966), and Gino  Severini (1883-1966). Russian Futurism, founded soon afterward by  Vladimir Mayakovsky and Velimir Khlebnikov (1885-1922), went beyond  the Italian model in its revolutionary political and social outlook. The  movement�s influence had ceased to be felt by 1930.</p><p>futurology Study of current trends in order to forecast future develop�  ments. The field originated in the �technological forecasting� developed  near the end of World War II and in studies examining the consequences  of nuclear conflict. Studies in the 1960s sought to anticipate future social  patterns and needs. The Limits of Growth by Dennis Meadows, et al.  (1972), focused on global socioeconomic trends, projecting a Malthusian  vision in which the collapse of the world order would result if popula�  tion growth, industrial expansion, pollution, food production, and natural-  resource use continued at current rates. Later reports reiterated many of  these concerns, with critics contending that futurologists� models were  flawed and futurologists responding that their analytic techniques were  becoming increasingly sophisticated. Other notable works include Alvin  Toffler�s Future Shock (1970), Daniel Bell�s The Coming of Post-  Industrial Society (1973), Jonathan Schell�s The Fate of the Earth (1982),  and Nigel Calder�s The Green Machines (1986).</p><p>Fuzhou or Fu-chou Vfu-'joN conventional Foochow Vfii-'chaCA/or-  merly Minhow City (pop., 2003 est.: 1,387,266), capital of Fujian prov�  ince, China.

During the Song  dynasty (960-1279), it was a centre for overseas trade and also an impor�  tant cultural centre. It reached its height of prosperity when it was opened  as a treaty port after the Opium War of 1839-42. It is now a centre for  industrial chemicals.

Considered the greatest figure  in classical Turkish literature, he composed poems with equal facility and  elegance in Turkish, Persian, and Arabic. His works transcended the  highly formalized Islamic literary aesthetic and influenced many poets up  to the 19th century. His most famous poems include his rendition of the  Muslim classic Leyla ve Mecnun, a celebrated allegory depicting the  attraction of the human spirit for divine beauty. His two poetry antholo�  gies, one in Azerbaijani Turkish and one in Persian, contain his most lyri�  cal verses.</p><p>fuzzy logic Logic based on the concept of fuzzy sets, in which mem�  bership is expressed in varying probabilities or degrees of truth�that is,  as a continuum of values ranging from 0 (does not occur) to 1 (definitely  occurs). As additional data are gathered, many fuzzy-logic systems are  able to adjust the probability values assigned to different parameters.  Because some such systems appear able to learn from their mistakes, they  are often considered a crude form of artificial intelligence. The term and  concept date from a 1965 paper by Lotfi A.

The son of Ivan IV, Fyo�  dor was feebleminded and took no part in the government, which was  dominated by his wife�s brother, Boris Godunov. Godunov was respon�  sible for the major achievements of Fyodor�s reign, including elevation  of the metropolitan see of Russia to a patriarchate (1589), recovery of  lands near the Gulf of Finland (1595), and strengthening of Russia�s con�  trol over western Siberia and territory in the Caucasus.

Gabon has more than 40 ethnic groups: the  Fang, more than one-fourth of the total population, live north of the  Ogooue River; the largest groups south of the river are the Sira (includ�  ing the Punu) and Nzebi. Languages: French (official), several Bantu lan�  guages (notably Fang). Religions: Christianity (mostly Roman Catholic;  also Protestant, other Christians); also Islam, traditional beliefs. Currency:</p><p>CFA franc. Gabon straddles the Equator on the western  coast of Africa. It has a narrow coastal plain and  becomes hilly in the south and north. The basin of its  chief river, the Ogooue, covers most of the country;  about three-fourths is equatorial rainforest, which sup�  ports numerous plant and animal species. Gabon has  reserves of manganese that are among the largest in the  world; it also has huge deposits of petroleum and natu�  ral gas. Gabon has a developing mixed economy based  largely on the exploitation of these mineral and timber  resources. Its chief of state is the president, and  the head of government is the prime minister; the  parliament consists of two houses. Artifacts dat�  ing from late Paleolithic and early Neolithic times have  been found in Gabon, but it is not known when the  Bantu speakers who established Gabon�s ethnic com�  position arrived. Pygmies were probably the original  inhabitants. The Portuguese began arriving in the late  15th century and were followed by French, Dutch, and  English traders. The Fang started migrating there in the late 18th  century. The slave trade dominated commerce in the 18th and much of the  19th century. The French then took control, and Gabon was administered  (1843-86) with French West Africa.

In 1800 the deeply religious  Gabriel planned a slave insurrection to create an independent slave state  in Virginia with himself as king. Intending to attack Richmond and kill  all whites except Frenchmen, Methodists, and Quakers, he assembled  1,000 slaves outside the city on August 30, but a violent rainstorm washed  out bridges and scattered the rebels.

He wrote more than 200 mad�  rigals and much other secular vocal music. His sacred vocal works, which  number more than 150, include many splendid settings for church festi�  vals; many were published posthumously in a collection called Concerti  (1587). His nephew and student, Giovanni, joined him as organist at St.  Mark�s in 1584. Like Andrea, he wrote numerous festive works for choirs  and instrumental groups. His best-known works are those for instruments,  especially wind instruments (canzonas, ricercars, sonatas, toccatas, etc.),  which employ dramatic dynamic and spatial effects.

The son  of a chemistry professor, Gadamer studied the humanities at the univer�  sities of Breslau, Marburg, Freiburg, and Munich, earning a doctorate in  philosophy under Heidegger at Freiburg in 1922. He later taught at the  universities of Frankfurt am Main (1947-49) and Heidelberg (from 1949),  where he became professor emeritus in 1968.

Gadwalls often live  in shallow freshwater ponds and marshes, often in mixed flocks with  wigeons. Unlike wigeons, they rarely feed on land.</p><p>Gaea Vje-o\ Greek goddess of the earth. She was both mother and wife  to Uranus, or Heaven, from whom  she was separated by her son Cro�  nus, a Titan. According to Hesiod, she  was the mother of all 12 Titans, as  well as of the Furies and the Cyclo�  pes (see Cyclops). She may have  originated as a mother goddess wor�  shiped in pre-Hellenic Greece before  the introduction of the cult of Zeus.</p><p>Gaelic Yga-lik\ football Irish  sport, an offshoot of the violent  medieval game melee.

With the 17th-  century English conquest and settlement of Ireland, Irish almost disap�  peared as a literary language. By the mid-19th century, translations of  heroic tales from ancient Irish manuscripts led to the popularity, among  the educated classes, of poets who wrote in patterns echoing ancient  bardic verse. The revival laid the scholarly and nationalistic groundwork  for the Irish Literary Renaissance.

Though little nota�  tion from before the 12th century survives, a mostly later body of music  continues to be performed at Shinto ceremonies. Gagaku employs trans�  verse flute ( ryuteki ), double-reed pipe ( hichiriki ), mouth organ ( slid ), gong  (shdko), drums, and stringed instruments including the biwa (see pipa) and  koto. It may accompany dance ( bugaku ) or be played independently (kan-  gen)\ it is further classified either as togaku, the so-called music of the  left (which included Chinese and Indian materials), or as komagaku, the  music of the right (including Korean examples).

Son of a carpenter on a collective farm, he graduated from  the Soviet air force�s cadet school in 1957. In April 1961, aboard Vostok  1, he became the first human to travel into space. The spacecraft orbited  Earth once in 1 hour 29 minutes. Gagarin�s flight brought him worldwide  fame, and he was much honoured in the Soviet Union. He never went into  space again, but he trained other cosmonauts. He was killed at age 34  when his jet crashed during a training flight.</p><p>Gahadavala dynasty \g9-h3-do-'va-l3\ (c. 1050-c. 1250) One of the  many ruling families of North India on the eve of the 12th-13th century  Muslim conquests. Its history illustrates all the features of the early medi�  eval North Indian polity�dynastic hostilities and alliances, feudal-state  structure, absolute dependence on Brahmanical social ideology, and vul�  nerability in the face of external aggression.

Developed c. 1972 largely by British  chemist James E. Lovelock and U.S. biologist Lynn Margulis, the Gaia  hypothesis is named for the Greek Earth goddess. It postulates that all  living things have a regulatory effect on the Earth�s environment that pro�  motes life overall; the Earth is homeostatic in support of life-sustaining  conditions. The theory is highly controversial.</p><p>Gainsborough, Thomas (baptized May 14, 1727, Sudbury,  Eng.�d. Aug. 2, 1788, London) British painter. At 13 he left his native  Suffolk to study in London. By c. 1750, back in Suffolk, he had estab�  lished a reputation in portraiture and landscape painting. He painted land�  scapes for pleasure; portraiture was his profession. In 1759 he moved to  the fashionable spa of Bath, where his works would be seen by a wider  and wealthier public. In 1768 he became a founding member of the Royal  Academy of Art. He developed an elegant, formal portrait style inspired  by Anthony Van Dyck, whose influence can be seen in such portraits as  his famous Blue Boy (1770). In 1774 he moved to London and became a  favourite of the royal family, preferred above the official court painter,</p><p>Joshua Reynolds.

Born a commoner, Gajah Mada  rose to power on his intelligence,  courage, and loyalty to King Jayana-  gara (r. 1309-28), whom he restored  to power after an insurrection. His  feelings for the king changed when  the latter took possession of his wife,  and he subsequently had the king  killed. During the reigns of Jayana-  gara�s daughter Tribhuvana and  grandson Hayam Wuruk (r. 1350-  89), Gajah Mada was the most pow�  erful figure in Majapahit, conquering  territories that may have included the  entire Indonesian archipelago and  part of Malaysia. A law book that had  great significance in Javanese history  was compiled under his instructions,  and the principal poet of the era, Pra-  pancha (fl. 14th century), eulogized  Gajah Mada (his patron) in Nagarakrtagama, the epic of Majapahit.</p><p>Gajdusek Vgl-do-.shekV D(aniel) Carleton (b.

He provided the first medical description of the  central-nervous-system disorder kuru, unique to the Fore people of New  Guinea, and concluded that it was spread by their funeral custom of ritu�  ally eating the deceased�s brains. With Clarence Gibbs, Jr., he proposed  that it was caused by an extremely slow-acting virus. Though kuru is now  known to be caused by prions, his study had significant implications for  research into multiple sclerosis, parkinsonism, and other degenerative  neurological conditions.

Their total land area of 3,093 sq mi (8,010 sq km) is scattered  over 23,000 sq mi (59,500 sq km) of ocean. Visited by the Spanish in  1535, they were unclaimed when Ecuador took official possession of them  in 1832. They became internationally famous after being visited in 1835  by British naturalist Charles Darwin; their unusual fauna, including the  giant tortoise (Spanish galapago), contributed to his ideas on natural  selection. Ecuador made the Galapagos a wildlife sanctuary in 1935 and  a national park in 1959; in 1978 they were designated a UNESCO World  Heritage site.</p><p>Galafi \ga-Tats, ga-'lat-se\ German Galatz \'ga-,lats\ City (pop., 2002:  298,584), southeastern Romania. Located at the confluence of the Danube  and Siret rivers, it was occupied by the Turks from the early 16th cen�  tury until 1829; its growth was encouraged by its status as a free port  (1837-83). During World War II, retreating German troops devastated the  town and reduced the population, substantially Jewish, to less than half.  Extensively rebuilt, it is one of Romania�s chief ports and the site of the  country�s largest shipyard.</p><p>Galatia \g3-Ta-sho\ Ancient district, central Anatolia.

In elliptical galaxies, which vary greatly in size, stars are distributed sym�  metrically in a spherical or spheroidal shape. Dwarf ellipticals (with only  a few million stars) are by far the most common kind of galaxy, though  none is conspicuous in the sky. Irregular galaxies, such as the Magellanic  Clouds, are relatively rare. Radio galaxies are very strong sources of radio  waves.

He became  chief physician to the gladiators in ad 157. Later, in Rome, he became a  friend of Marcus Aurelius and physician to Commodus. Galen saw anatomy  as fundamental and, based on animal experiments, described cranial  nerves and heart valves and showed that arteries carry blood, not air. How�  ever, in extending his findings to human anatomy he was often in error.  Following Hippocratic concepts (see Hippocrates), he believed in three  connected body systems�brain and nerves for sensation and thought,  heart and arteries for life energy, and liver and veins for nutrition and  growth�and four humours (body fluids)�blood, yellow bile, black bile,  and phlegm�that needed to be in balance. Few had the skills to challenge  his seductive physiological theory. He wrote about 300 works, of which  about 150 survive. As they were translated, his influence spread to the  Byzantine Empire, Arabia, and then western Europe. A revival of interest  in the 16th century led to new anatomical investigations, which caused the  overthrow of his ideas when Andreas Vesalius found anatomical errors and  William Harvey correctly explained blood circulation.</p><p>galena \g3-Te-no\ or lead glance Gray lead sulfide (PbS), the chief  ore mineral of lead.

It included the northern  slopes of the Carpathian Mountains and the valleys of the upper Vistula,  Dniester, Bug, and Seret rivers. In 1199 eastern Galicia, situated near the  principalities of Kiev and Volhynia, was taken by Prince Roman of Vol-  hynia, who united Volhynia and Galicia. In 1349 the Polish king Casimir  III annexed Galicia. When Poland was partitioned, beginning in 1772, the  territory passed to Austria. Restored to Poland after World War I, eastern  Galicia was taken by the Soviet Union in World War II and united to the  Ukrainian S.S.R. After the war, eastern Galicia remained a part of the  U.S.S.R.

Its name is derived  from the Celtic Gallaeci, who lived there when the region was conquered  by the Romans c. 137 bc. Taken by the Visigoths in ad 585, it next passed  to the Moors and became part of the kingdom of Asturias in the 8th and 9th  centuries.

Feb. 15, 1564, Pisa�d.  Jan. 8, 1642, Arcetri, near Florence) Italian mathematician, astronomer,  and physicist. Son of a musician, he studied medicine before turning his  attention to mathematics. His invention of the hydrostatic balance (c.  1586) made him famous. In 1589 he published a treatise on the centre of  gravity in solids, which won him the post of mathematics lecturer at the  University of Pisa. There he disproved the Aristotelian contention that  bodies of different weights fall at different speeds; he also proposed the  law of uniform acceleration for falling bodies and showed that the path  of a thrown object is a parabola. The first to use a telescope to study the  skies, he discovered (1609-10) that the surface of the Moon is irregular,  that the Milky Way is composed of stars, and that Jupiter has moons (see  Galilean satellite). His findings led to his appointment as philosopher and  mathematician to the grand duke of Tuscany. During a visit to Rome  (1611), he spoke persuasively for the Copernican system, which put him  at odds with Aristotelian professors and led to Copernicanism�s being  declared false and erroneous (1616) by the church. Obtaining permission  to write about the Copernican system so long as he discussed it noncom�  mittally, he wrote his Dialogue Concerning the Two Chief World Systems  (1632). Though considered a masterpiece, it enraged the Jesuits, and Gali�  leo was tried before the Inquisition, found guilty of heresy, and forced to  recant.

Pear-shaped and expandable, it holds about 1.7 fluid oz  (50 ml). Its inner surface absorbs water and inorganic salts from bile,  which becomes 5-18 times more concentrated than when it leaves the  liver. The gallbladder contracts to discharge bile through the bile duct into  the duodenum. Disorders include gallstones and inflammation (cholecys�  titis). Surgical removal of the gallbladder (cholecystectomy) has no seri�  ous side effects.</p><p>Galle \ga-'la\, Emile (b. May 8, 1846, Nancy, Fr.�d. Sept. 23, 1904,  Nancy) French glass and furniture  designer. From 1867 he worked in  his father�s faience and furniture fac�  tory in Nancy. His deeply coloured  opaque pieces, layered and carved or  etched with plant motifs, were a  great success at the Paris Exhibitions  of 1878 and 1889 and were widely  imitated. He used wheel cutting, acid  etching, casing, and such special  effects as metallic foil and air  bubbles to produce what he called  �marquetry of glass.� His furniture  designs featured floral inlay and  carving; some incorporated inlaid  quotations from well-known authors.</p><p>A proponent of the Art Nouveau  style, he collaborated with many col�  leagues, notably Louis Majorelle.</p><p>gallery In architecture, a long,  covered space open on one side, such  as a portico or a colonnade. It may  be recessed into a wall or elevated on  columns or corbels, and it often  serves as a passageway. Within an  interior, a gallery may be a platform  or upper floor projecting from a wall  (e.g., in a legislative house) with  seating for spectators. In a church nave, the long, narrow platforms sup�  ported by colonnades are called tribune galleries. In a theatre, the gallery  is the highest balcony and generally has the cheapest seats. Galleries  appeared in Renaissance houses as long, narrow rooms used both as prom�  enades and to exhibit art. The modem art gallery is their descendant.</p><p>galley Farge seagoing vessel propelled primarily by oars. The Egyp�  tians, Cretans, and other ancient peoples used sail-equipped galleys for  war and commerce. The Phoenicians apparently introduced the bireme (c.  700 bc), which had two banks of oars staggered on either side. The Greeks  first built the trireme c. 500 bc. War galleys would cruise in columns and  would engage the enemy as a line abreast. A galley would close with the  enemy at the bow, which was equipped with a ram, grappling irons, and  missile-hurling devices. Invention of the lateen (fore-and-aft) sail and the  stem rudder rendered the galley obsolete for commerce, but its greater  maneuverability maintained its military importance into the 16th century.

The family took its final name from  the birthplace of its progenitor, the artist Giovanni Maria Galli (1625-  65). His descendants are noted for dazzling theatrical designs of spacious  proportions achieved by the use of intricate perspective. Giovanni�s son  Ferdinando Galli Bibiena (1657-1743) studied painting and architecture</p><p>and worked for the duke of Parma. He designed scenery for court fes�  tivities and operas in Barcelona and Vienna and was architect of the royal  theatre at Mantua. His brother Francesco (1659-1739) was the ducal  architect at Mantua and built theatres in Vienna, Nancy (France), Verona,  and Rome. Ferdinando�s son Giuseppe (1696-1757), the most distin�  guished of the family, remained in Vienna to become chief organizer of  splendid court functions. Engravings of his stage sets were published in  three series (1716, 1723, 1740-44). He designed the interior of the the�  atre at Bayreuth in 1748. His brothers Alessandro and Antonio were also  architects and designers of note. His son Carlo (1728-87), the last of the  illustrious family, worked in theatres throughout Europe.</p><p>Gallia Narbonensis See Narbonensis</p><p>Gallic Wars (58 -50 bc) Campaigns in which Julius Caesar conquered  Gaul. Clad in his blood-red cloak as a �distinguishing mark of battle,� he  led his troops to victories throughout the province, relying on superior  strategy, tactics, discipline, and military engineering. In 58 he drove back  the Helvetii from Rome�s northwestern frontier, then subdued the Belgic  group of Gallic peoples in the north (57), reconquered the Veneti (56),  crossed the Rhine River to raid Germany (55), and crossed the English  Channel to raid Britain (55, 54). His major triumph was the defeat of  Vercingetorix in 52. He described the campaigns in De bello Gallico.</p><p>Gallicanism Vga-la-ko-.ni-zomX French eccelesiastical and government  policies designed to restrict the papacy�s power. It affirmed the indepen�  dence of the French king in the temporal realm, the superiority of an ecu�  menical council over the pope, and the union of king and clergy to limit  the intervention of the pope within France. Gallicanism was opposed to  Ultramontanism, which championed papal authority. The doctrine was  important in the medieval struggle between church and state. In 1438,  after several conflicts between kings and popes, Charles VII issued the  Pragmatic Sanction of Bourges, affirming that a pope was subject to a gen�  eral council and that his jurisdiction was conditioned by the royal will.</p><p>Gallieni \gal-ya-'ne\, Joseph Simon (b. April 24, 1849, Saint-Beat,  France�d. May 27, 1916, Versailles) French army officer. As governor  of the French Sudan (1886-88), he successfully combated rebel Sudanese  forces. After service in Indochina (1892-96), he returned to Africa as  governor-general of Madagascar (1896-1905) and won a reputation as a  judicious and flexible colonial master. He successfully integrated both  African territories into the French colonial empire. Named military com�  mander of Paris just before World War I, he fought in the First Battle of  the Marne and became minister of war in 1915. He was posthumously  created marshal of France (1921).</p><p>Gallienus V.gal-e-'e-nssV Publius Licinius Egnatius (b. c. 218�d.</p><p>268) Roman emperor who ruled jointly with his father, Valerian (253-  260), then alone (260-268). With the empire disintegrating under foreign  invasions, the Senate made Gallienus co-emperor. He took charge of the  western frontiers, winning a series of battles against the Goths and oth�  ers. When the Persians devastated the East and his father died in captiv�  ity, Gallienus was left with only Italy and the Balkans. Later the Goths  attacked anew; he was killed while trying to put down an insurgency. His  reforms as emperor included the transfer of army command to profes�  sional equestrian officers, expansion of the cavalry, and an intellectual  renaissance at Rome, discernible in its art and literature.</p><p>gallinule Vga-lo-.ntilX Any of several species of marsh birds (family  Rallidae) found in temperate, tropi�  cal, and subtropical regions world�  wide.

Silvery white and soft enough to be cut with a knife, gallium has  an unusually low melting point (about 30 �C [86 �F]), which allows it to  liquefy in the palm of the hand. The liquid metal clings to or wets glass  and similar surfaces. Gallium expands on solidification and supercools  readily, remaining liquid at temperatures as low as 0 �C (32 �F). In vari�  ous combinations with aluminum, indium, phosphorus, arsenic, and antimony,  it forms compounds (e.g., gallium arsenide and indium gallium arsenide  phosphide) with valuable semiconductor and optoelectronic properties;  some of these compounds form the basis for such electronic devices as  light-emitting diodes and semiconductor lasers.</p><p>Galloway, Joseph (b. c. 1731, West River, Md.�d. Aug. 29, 1803,  Watford, Hertfordshire, Eng.) American colonial lawyer and legislator.  Entering law practice in Philadelphia in 1747, Galloway won a reputation  by pleading cases before the Supreme Court of Pennsylvania before he  was 20. He was elected to the colonial legislature in 1756 and served as  speaker from 1766 to 1775. A loyalist, he opposed the independence of  the colonies; his plan for a peaceful resolution of the conflict with Brit�  ain was narrowly rejected by the Continental Congress. During the Ameri�  can Revolution Galloway joined the British army under William Howe,  becoming a civil administrator of Philadelphia during the British occu�  pation of the city. When the Continental Army reentered Philadelphia in  1778, he fled to England.</p><p>gallstone Mass of crystallized substances that forms in the gallbladder.  The most common type occurs when the liver secretes bile with too much  cholesterol to stay in solution. Liver damage, chronic gallbladder disease,  or biliary-tract cancer may predispose one to stone formation. In the gall�  bladder, stones may cause inflammation or produce no symptoms. A stone  obstructing the bile duct causes severe pain (biliary colic). Gallstones  usually must be removed with the gallbladder or broken up with ultra�  sound. In some cases a stone can be treated by giving the patient bile  salts, which help redissolve cholesterol. If the gallbladder must be  removed, laparoscopy is the method of choice.</p><p>Gallup, George (Horace) (b. Nov. 18, 1901, Jefferson, Iowa,  U.S.�d. July 26, 1984, Tschingel, Switz.) U.S. public-opinion statisti�  cian. He taught journalism at Drake University and Northwestern Uni�  versity until 1932, when a New York advertising firm hired him to conduct  public-opinion surveys for its clients. He became a pioneer in the scien�  tific sampling of public opinion, and his Gallup Poll, as well as other  public-opinion polls, gained credibility after correctly forecasting the  1936 presidential victory of Franklin D.

Galsworthy gave up a law career to become a writer,  and many of his works have legal themes. He published several works  before The Man of Property (1906), the first novel of The Forsyte Saga  (completed 1922). The family chronicle by which he is chiefly remem�  bered, it consists of three novels linked by two interludes. He continued  the story of the Forsytes in three further novels collected in A Modern  Comedy (1929). His plays, written in a naturalistic style, usually exam�  ine a controversial ethical or social problem; they include The Silver Box  (1906), Strife (1909), Justice (1910), and Loyalties (1922). He won the  Nobel Prize for Literature in 1932.</p><p>Galt, Sir Alexander Tilloch (b. Sept. 6, 1817, London, Eng.�d.  Sept. 19, 1893, Montreal, Que., Can.) British-Canadian statesman. He  immigrated to Lower Canada (later Quebec) in 1835 and worked for the  British-American Land Co., serving as high commissioner from 1844 to  1855. He entered politics in 1849 as an independent member for Sher�  brooke county in the legislature of the united province of Canada. He  resigned from the legislature in 1850 but was reelected for Sherbrooke</p><p>town in 1853. He maintained that seat and remained leader of the English-  speaking minority until 1872. As finance minister (1858-62, 1864-67),  he advocated federation; following the creation of the Dominion of  Canada, he became the first finance minister of the Dominion government  (1867-68). After retiring from Parliament in 1872, he advocated Cana�  dian independence. From 1880 to 1883 he served as the first Canadian  high commissioner in London.</p><p>Gallon, Sir Francis (b.

Galton, a cousin  of Charles Darwin, studied medicine  at Cambridge University but never  took a degree. As a young man he  traveled widely in Europe and  Africa, making useful contributions  in zoology and geography. He was  among the first to recognize the  implications of Darwin�s theory of  evolution, eventually coining the  word eugenics to denote the science  of planned human betterment  through selective mating. His aim  was the creation not of an aristocratic  elite but of a population consisting  entirely of superior men and women.  He also wrote important works on  human intelligence, fingerprinting,  applied statistics, twins, blood trans�  fusions, criminality, meteorology,  and measurement.</p><p>Sir Francis Galton, detail of an oil  painting by G.

His early research focused on comparative anatomy, includ�  ing the structure of kidney tubules and the middle ear. His developing  interest in electricity was inspired by the fact that dead frogs underwent  convulsions when attached to an iron fence to dry. He experimented with  muscular stimulation by electrical means, using an electrostatic machine  and a Leyden jar, and from the early 1780s animal electricity remained  his major field of investigation. His discoveries led to the invention of the  voltaic pile, a kind of battery that makes possible a constant source of  current electricity.</p><p>galvanizing Protection of iron or steel against exposure to the atmo�  sphere and consequent rusting by application of a zinc coating. Properly  applied, galvanizing may protect from atmospheric corrosion for 15-30  years or more. If the coating is damaged, the iron or steel continues to be  protected by sacrificial corrosion, a phenomenon in which atmospheric  oxidation spares the iron and affects the zinc (as long as it lasts).

A common galvanometer  consists of a light coil of wire suspended from a metallic ribbon between  the poles of a permanent magnet. As current passes through the coil, the  magnetic field it produces reacts with the magnetic field of the permanent  magnet, producing a torque. The torque causes the coil to rotate, moving  an attached needle or mirror. The angle of rotation, which provides a  measure of the current flowing in the coil, is measured by the movement  of the needle or by the deflection of a beam of light reflected from the  mirror.</p><p>Galveston City (pop., 2000: 57,247) and port of entry, southeastern  Texas, U.S. Located at the northeastern end of Galveston Island in the  Gulf of Mexico, it was the pirate Jean Laffite�s headquarters (1817-21).  Settlement of the island then began, and the town of Galveston was laid  out in 1834; during the Texas revolt against Mexico (1835-36), it briefly  served as the capital. During the American Civil War it was an important  Confederate supply port.

Portugal�s King Manuel I acted quickly to open trade routes with India,  but a massacre of Portuguese in India caused him to dispatch a fleet of  20 ships in 1502, led by da Gama, to establish Portuguese supremacy in  the region. Da Gama, then an admiral, forced allegiance along the way  from local rulers and attacked Arab shipping. After various battles, he  secured obedience to Portuguese rule and returned home. In 1524 he was  appointed Portuguese viceroy in India but died shortly after arriving in  Goa.

Language: English  (official). Religions: Islam; also Christianity. Currency: dalasi. The Gam�  bia has a wet-and-dry tropical climate and is generally hilly, with savanna  in the uplands and swamps in low-lying areas. It has a developing market  economy based largely on the production and export of peanuts, though  only about one-fourth of the land is arable. The river serves as a major  transportation artery. Tourism is an important source of revenue. The  Gambia is a republic with one legislative body; its head of state and gov�  ernment is the president. Beginning about the 13th century ad, the Wolof,  Malinke, and Fulani peoples settled in different parts of what is now The  Gambia and established villages and then kingdoms in the region. Euro�  pean exploration began when the Portuguese sighted the Gambia River in  1455. In the 17th century, when Britain and France both settled in the area,  the British Fort James, on an island about 20 mi (32 km) from the river�s  mouth, was an important collection point for the slave trade. In 1783 the  Treaty of Versailles reserved the Gambia River for Britain. After the Brit�  ish abolished slavery in 1807, they built a fort at the mouth of the river to  block the continuing slave trade. In 1889 The Gambia�s boundaries were  agreed upon by Britain and France; the British declared a protectorate over  the area in 1894. Independence was proclaimed in 1965, and The Gambia  became a republic within the Commonwealth in 1970. It formed a limited  confederation with Senegal in 1982, which was dissolved in 1989. During  the 1990s the country faced political problems, but its biggest concern has  come to be its poor economy.</p><p>Gambia River River, western Africa.

Commonly associated with gambling are horse racing,  boxing, numerous playing-card and dice games, cockfighting, jai alai, rec�  reational billiards and darts, bingo, and lottery. In most gambling games it  is customary to express the idea of probability in terms of �odds against  winning.� In the U.S. casino gambling, once highly restricted, is now legal  in many states, and lotteries are employed by many states to raise rev�  enues.

Among the shows  popular on U.S. radio were Dr. I.Q. (1939-49), Information, Please  (1938-48), and The Quiz Kids (1940-53). The genre was adopted by tele�  vision and cash awards were increased, so that radio�s $64 Question  became television�s $64,000 Question. In the mid-1950s, to increase their  shows� popularity, some producers began feeding answers to contestants  who had been chosen to win. An accusation of unfair practices on Twenty-  one (1958) led to a government investigation and the quick demise of the  big-money shows. The game show later regained popularity when it was  revived in formats with lower stakes and easier questions, as on Jeop�  ardy! and Wheel of Fortune. At the turn of the 21st century, game shows  such as Who Wants to Be a Millionaire boasted large cash prizes and  gained popularity in prime time, and reality shows like Survivor adopted  aspects of the game show genre.</p><p>game theory Branch of applied mathematics devised to analyze cer�  tain situations in which there is an interplay between parties that may have  similar, opposed, or mixed interests. Game theory was originally devel�  oped by John von Neumann and Oscar Morgenstem in their book The  Theory of Games and Economic Behavior (1944). In a typical game, or  competition with fixed rules, �players� try to outsmart one another by  anticipating the others� decisions, or moves. A solution to a game pre�  scribes the optimal strategy or strategies for each player and predicts the  average, or expected, outcome. Until a highly contrived counterexample  was devised in 1967, it was thought that every contest had at least one  solution.

The  alternate, nonsexual phase is the sporophyte. In the gametophyte phase,  male and female organs (gametangia) develop and produce eggs and  sperm (gametes), which unite in fertilization (syngamy). The fertilized  egg (zygote) develops into the sporophyte, which produces numerous  single-celled spores, which in turn develop directly into new gametes.</p><p>gamma decay Type of radioactivity in the most common form of  which an unstable atomic nucleus dissipates energy by gamma emission,  producing gamma rays. Gamma decay also includes two other processes,</p><p>internal conversion and internal pair production. In internal conversion,  excess energy in a nucleus is transferred to one of its own orbiting elec�  trons and the electron is ejected from the atom. In internal pair produc�  tion, excess energy is converted into an electron and a positron, which are  emitted together. Typical half-lives (see half-life) for gamma emission  range from about 10 -9 to 10 -14 second.</p><p>gamma globulin Vglab-yo-bnX Subgroup of the globulins. In humans  and many other mammals, most antibodies are in the gamma globulin  fraction of blood. A human gamma globulin preparation may be admin�  istered (by injection) to persons lacking immunity, either generally or to a  particular disease, after exposure or before expected exposure.</p><p>gamma ray Penetrating very short-wavelength electromagnetic radia�  tion, similar to an X-ray but of higher energy, that is emitted spontaneously  by some radioactive substances (see gamma decay; radioactivity). Gamma  radiation also originates in the decay of certain subatomic particles and in  particle-antiparticle annihilation (see also antimatter). Gamma rays can ini�  tiate nuclear fission, can be absorbed by ejection of an electron (see pho�  toelectric effect), and can be scattered by free electrons (see Compton effect).</p><p>gamma-ray astronomy Study of astronomical objects and phe�  nomena that emit gamma rays. Gamma-ray telescopes are designed to  observe high-energy astrophysical systems, including stellar coronas,  WHITE DWARF STARS, NEUTRON STARS, BLACK HOLES, SUPERNOVA remnants, CLUSTERS  OF galaxies, and diffuse gamma-ray background radiation found along the  plane of the Milky Way Galaxy. Because Earth�s atmosphere blocks most  gamma rays, observations are generally conducted by high-altitude bal�  loons or spacecraft. In the 1960s defense satellites designed to detect X  rays and gamma rays from clandestine nuclear testing serendipitously  discovered enigmatic gamma-ray bursts coming from deep space. In the  1970s Earth-orbiting observatories found a number of gamma-ray point  sources, including an exceptionally strong one, dubbed Geminga, that was  later identified as a pulsar, the nearest yet detected. The Compton Gamma  Ray Observatory, launched in 1991, mapped thousands of celestial  gamma-ray sources; it also showed that the mysterious bursts are distrib�  uted across the sky, implying that their sources are at the distant reaches  of the universe rather than in the Milky Way.</p><p>Gamow Vga-.moft, George orig. Georgy Antonovich Gamov</p><p>(b. March 4, 1904, Odessa, Russian Empire�d. Aug. 19, 1968, Boulder,  Colo., U.S.) Russian-born U.S. nuclear physicist and cosmologist. After  studying at Leningrad University with Aleksandr Friedmann (1888�  1925), he subsequently developed his quantum theory of radioactivity, the  first successful explanation of the behaviour of radioactive elements. His  �liquid drop� model of atomic nuclei served as the basis for modern theo�  ries of nuclear fission and fusion. After immigrating to the U.S. in 1934,  he collaborated with Edward Teller in researching beta decay (1936) and  developing a theory of the internal structures of red giant stars (1942). In  the 1950s he became interested in biochemistry, proposing theories of  genetic code structure that were later found to be true. Throughout his  career he also wrote popular works on such difficult subjects as relativity  and cosmology.</p><p>Gan \'gan\ River or Kan River River, southeastern China. Located  in Jiangxi province, it flows north through Lake Poyang to enter the  Yangtze River (Chang Jiang) after a course of 506 mi (815 km). A major  southern tributary of the Yangtze, the Gan valley provided an important  route in historical times from Guangzhou to the Yangtze valley and the  north.</p><p>Ganca \gan-'ja\ formerly (1804-1918) Yelizavetpol� \yi-li-z3-'vyet-  ,pol\ or (1935-89) Kirovabad \ l ke-ro-v9- , bat\ City (pop., 1997 est.:  291,900), western Azerbaijan. It lies along the Ganca River. A town was  founded nearby in the 5th century ad, was destroyed by earthquake in  1139, and was rebuilt on the present site. Taken by the Mongols in 1231,  it was captured in 1606 by the Persian Safavid dynasty, who made it the  centre of the Ganca khanate. The Russians annexed it in 1804 and  renamed it Yelizavetpol�. In 1935 it was renamed Kirovabad and devel�  oped industrially to become one of the largest cities of Azerbaijan. It  manufactures aluminum, machinery, and instruments and is an agricul�  tural processing centre. Notable buildings include Dzhuma-Mechet  Mosque (1620) and the mausoleum of the 12th-century Persian poet  NezamI, a lifelong resident of the city.</p><p>Gance \'ga n s\, Abel orig.

He worked in the cinema from 1909, finally winning  acclaim with Mater dolorosa (1917) and Tenth Symphony (1918). His  J�accuse (1918) and The Wheel (1923) were hailed as masterpieces. He  devoted four years to his greatest film, Napoleon (1927), in which he used  experimental techniques to emphasize cinematic movement. Battle  sequences were shot with three synchronized cameras, and the images  were projected on a triple screen to produce a three-dimensional effect;  the film also pioneered the use of stereophonic sound. A triumph in  Europe, it fared badly in a harshly edited version in the U.S. but was  finally released in its original glory in 1981. Gance�s later films, largely  controlled by the studios, gave inadequate scope for his creative genius.</p><p>Ganda or Baganda People of southern Uganda. They speak Luganda,  a Bantu language of the Benue-Congo group. Numbering 3.7 million, the  Ganda are Uganda�s largest ethnic group. Traditionally hoe cultivators,  they also grow cotton and coffee for export and keep livestock. In the  19th century the Ganda developed the centralized state known as Buganda.</p><p>Gandhara art Style of Buddhist art that developed in what is now  northwestern Pakistan and eastern  Afghanistan from the 1st to the 7th  century ad. It was contemporaneous  with Mathura art. The Gandhara  region had earlier been a site of much  Buddhist missionary activity, and the  Kushan rulers maintained contact  with Rome; the Gandhara school  incorporated motifs and techniques  from Classical Roman art (e.g., vine  scrolls, cherubs with garlands, tri�  tons, centaurs), but the iconography  was based on the interpretation of  Buddhist legends. Sculptural materi�  als included green phyllite, gray-blue  mica, and stucco; sculptures were  originally painted and gilded.

Oct. 31,</p><p>1984, New Delhi) Prime minister of  India (1966-77, 1980-84). The only  child of Jawaharlal Nehru, she stud�  ied in India and at the University of  Oxford. In 1942 she married Feroze  Gandhi (d. 1960), a fellow member  of the Indian National Congress. In  1959 she was given the largely hon�  orary position of party president, and  in 1966 she achieved actual power  when she was made leader of the  Congress Party and, consequently,  prime minister. She instituted major  reforms, including a strict  population-control program. In 1971  she mobilized Indian forces against  Pakistan in the cause of East Ben�  gal�s secession. She oversaw the  incorporation of Sikkim in 1974.</p><p>Convicted in 1975 of violating elec�  tion laws, she declared a state of  emergency, jailing opponents and passing many laws limiting personal  freedoms. She was defeated in the following election but returned to  power in 1980. In 1984 she ordered the army to move into the Golden  Temple complex of the Sikhs at Amritsar, with the intent of crushing the  Sikh militants hiding inside the temple; some 450 Sikhs died in the fight�  ing. She was later shot and killed by her own Sikh bodyguards in revenge.</p><p>Gandhi, Mohandas K(aramchand) known as Mahatma  Gandhi (b. Oct. 2, 1869, Porbandar, India�d. Jan. 30, 1948, Delhi)  Preeminent leader of Indian nationalism and prophet of nonviolence in  the 20th century. Gandhi grew up in a home steeped in religion, and he  took for granted religious tolerance and the doctrine of ahimsa (noninjury  to all living beings). He studied law in England but seemed too diffident</p><p>to become a successful lawyer. He took a job with an Indian firm in South  Africa. There he became an effective advocate for Indian rights. In 1906  he first put into action satyagraha, his technique of nonviolent resistance.  His success in South Africa gave him an international reputation, and in  1915 he returned to India and within a few years became the leader of a  nationwide struggle for Indian home rule. By 1920 Gandhi commanded  influence hitherto unattained by any political leader in India. He refash�  ioned the Indian National Congress into an effective political instrument  of Indian nationalism and undertook major campaigns of nonviolent resis�  tance in 1920-22, 1930-34 (including his momentous march to the sea  to collect salt to protest a government monopoly), and 1940-42. In the  1930s he also campaigned to end discrimination against India�s untouch�  able class�whom he renamed Harijans (literally �children of God�)�  and concentrated on educating rural India and promoting cottage industry.  India achieved dominion status in 1947, but the partition of the subcon�  tinent into India and Pakistan was a great disappointment to Gandhi, who  had long worked for Hindu-Muslim unity. In September 1947 he ended  rioting in Calcutta (Kolkata) by fasting. Known as the Mahatma (�Great-  Souled�), Gandhi had won the affection and loyalty of millions. In Janu�  ary 1948 he was shot and killed by a young Hindu fanatic.</p><p>Gandhi, Rajiv (Ratna) (b. Aug. 20, 1944, Bombay [Mumbai],  India�d. May 21, 1991, Sriperumbudur, near Madras [Chennai]) Indian  politician, prime minister of India (1984-89). Son of Indira Gandhi, he  studied engineering at the University of Cambridge and became a com�  mercial airline pilot in 1968. He entered politics after the death of his  brother, Sanjay, in 1980. Sworn in as prime minister the day his mother  was assassinated (Oct. 31, 1984), he led the Congress (I) Party to a land�  slide victory in elections that year. His administration took vigorous mea�  sures to reform the government bureaucracy and liberalize the country�s  economy, but his attempts to discourage separatist movements failed, and  his government became embroiled in financial scandals. He resigned in  1989 but remained leader of the Congress (I) Party. He was assassinated  in 1991 while running for reelection.</p><p>Gandhinagar ^gon-do-'no-gorV City (pop., 2001 prelim.: 195,891),  capital of Gujarat state, west-central India. It lies on the banks of the  Sabarmati River, north of the former capital of Ahmedabad. Built to sup�  plant the former capital, after the state of Bombay was divided, the city  was begun in 1966 and named for Mohandas K. Gandhi. The first state  government offices were transferred there in 1970, and the city subse�  quently continued to grow.</p><p>Gando See Gwandu</p><p>Ganesha \g9-'na-sho\ or Ganesa Elephant-headed Hindu god, the  son of Shiva and Parvati. He is also  revered in Jainism, and he is impor�  tant in the art and mythology of Bud�  dhist Asia. As the remover of  obstacles, Ganesha is invoked when  beginning worship or starting any  new venture. He was popular with  Indian nationalists, who saw British  colonialism as one obstacle to be  removed. The patron of letters and  learning, he is the legendary scribe  who wrote down the Mahabharata.</p><p>His popularity continued to grow  through the 20th century. His festi�  val is especially popular in the Indian  state of Maharashtra.</p><p>Gang of Four Most powerful  members of a radical political elite  convicted for implementing the  harsh policies of Mao Zedong during  the Cultural Revolution. The four  were Wang Hongwen, Zhang Chun-  qiao, Yao Wenyuan, and Mao�s third  wife, Jiang Qing. Manipulating the youthful Red Guards, the Gang of Four  controlled four areas: intellectual education, basic theories in science and  technology, teacher-student relations and school discipline, and party poli�  cies regarding intellectuals. The turmoil of the Cultural Revolution sub�  sided after 1969, but the Gang of Four maintained their power until Mao�s  death in 1976, when they were imprisoned; they stood trial in 1980-81.</p><p>The Buddha preaching, relief from  Gandhara, schist, c. 2nd century ad; in  the Prince of Wales Museum of West�  ern India, Bombay.</p><p>P.

An area of about 220 mi (355 km)  wide along the Bay of Bengal, it is covered by the network of streams  forming the mouths of the Ganges (Ganga) and Brahmaputra rivers. In  Bangladesh the Brahmaputra is joined by the Tista River and, from there  to its junction with the Ganges, is known as the Jamuna River. The main  streams, the Ganges and the Jamuna, unite to form the Padma River. The  river farthest west that enters the Bay of Bengal is the Hugli River. Many  smaller streams of the delta form a swamp region for about 160 miles  (260 km) along the coast, known as the Sundarbans. The delta was struck  in 1970 by one of history�s most devastating cyclones.</p><p>Ganges Vgan-jez\ River Hindi Ganga Vgoq-goV River, northern  India and Bangladesh. Held sacred by followers of Hinduism, it is formed  from five headstreams rising in Uttaranchal state. On its 1,560-mi (2,510-  km) course, it flows southeast through the Indian states of Uttar Pradesh,  Bihar, and West Bengal. In central Bangladesh it is joined by the Brah�  maputra and Meghna rivers. Their combined waters (called the Padma  River) empty into the Bay of Bengal and form a delta 220 mi (354 km)  wide, which is shared by India and Bangladesh. Its plain is one of the  most fertile and densely populated regions in the world. Millions of Hin�  dus bathe in the river annually at special holy places ( tirthas ). Many cast  the ashes of their dead into its waters, and cremation temples are found  along its banks in numerous places.</p><p>Gangetic \gan-'je-tik\ Plain or Indo-Gangetic Plain Fertile low�  land region of north-central India. It stretches westward, centred on the  Ganges River, from the Brahmaputra River valley and the Ganges delta to  the Indus River valley. It contains the subcontinent�s richest and most  densely populated areas. The greater part of the plain is made up of allu�  vial soil, deposited by the extensive network of rivers in the region. The  eastern part of the plain has summer rainfall so heavy that vast areas  become swamps or shallow lakes. It becomes progressively drier toward  the west, where it incorporates the Thar Desert.</p><p>ganglion \'gaq-gle-on\ Aggregate of nerve-cell bodies outside the cen�  tral nervous system (CNS). The spinal ganglion contains the nerve-cell  bodies of the nerve fibres that carry impulses toward the CNS (afferent  neurons in dorsal root ganglia) or away from it (efferent neurons in ven�  tral root ganglia).</p><p>gangrene Localized soft-tissue death (necrosis) from prolonged blood-  supply blockage. It can occur in atherosclerosis, diabetes mellitus, or decu�  bitus ulcer, and after severe burns or frostbite. In dry gangrene, gradual  blood-supply decrease turns the part discoloured and cold, then dark and  dry. Treatment requires improving blood flow. Moist gangrene comes  from a sudden blood-supply cutoff. Bacterial infection causes swelling,  discoloration, and then a foul smell. Along with antibiotics, tissue removal  may be needed to prevent spread, which can be fatal. A more virulent  form, gas gangrene, is named for gas bubbles under the skin produced by  a highly lethal toxin from Clostridium bacteria. The wound oozes brown�  ish, smelly pus. Infection spreads rapidly, causing death. All dead and  diseased tissue must be removed and antibiotics given; an antitoxin can  also be used.</p><p>Gangtok Vgoq-.tokV Town (pop., 2001 prelim.: 29,162), capital of Sik�  kim state, northeastern India. At an elevation of 5,600 ft (1,700 m), it over�  looks the Ranipool River. It was the governmental seat of the kingdom  of Sikkim until the monarchy was abolished (1975) and India annexed  Sikkim (1976). It was an important point on the India-Tibet trade route  until the border with Tibet was closed in 1962. The former royal palace  and chapel are located there; the noted Buddhist monastery of Rumtek is  nearby.</p><p>Ganioda'yo \,gan-yo-'dI-yo\ or Handsome Lake (b. c. 1735,  Ganawaugus, N.Y.�d.

He led a somewhat dissolute life before becoming seriously  ill in 1799; on recovering, he reported a vision revealing the will of the</p><p>Great Spirit. He developed a religion he called Gai�wiio (Good Message)  that combined elements of Christianity and Indian beliefs; as an itinerant  preacher, he urged his people to refrain from adultery, drunkenness, lazi�  ness, and witchcraft. The religion revitalized the demoralized Iroquois,  and it was adhered to by many into the 20th century.</p><p>gannet Any of three oceanic bird species (family Sulidae) closely  related to the booby. Gannets are  found in the North Atlantic, where  they are the largest seabirds, and in  temperate waters around Africa,</p><p>Australia, and New Zealand. Adults  are mainly white with black-tipped  wing feathers and a large, yellowish  or buff-coloured head marked with  black around the eyes. They have a  tapered beak and pointed tail. They  dive with half-closed wings to catch  fish and squid. They waddle on land  but are expert fliers, spending most  of their lives over water. They nest  in dense colonies on cliffs. The larg�  est species is the 40-in. (100-cm)  northern gannet.</p><p>Gannett Co., Inc. One of the largest newspaper groups in the U.S. It  was founded by Frank Ernest Gannett (1876-1957), who in 1906 began  buying small newspapers in upstate New York. It was incorporated in  1923, and its stock was first publicly traded in 1967. In 1982 it began  publishing USA Today, the first national general-interest newspaper in the  U.S. By 2005 Gannett owned about 100 daily papers, with a combined  circulation of more than 7 million. Most of its newspapers are located in  small and medium-sized cities; Gannett�s larger papers include the Des  Moines Register and the Detroit Free Press.

Its capital is Lanzhou. For centuries a passage  between the upper Huang He (Yellow River) region and western China,  it became part of Chinese territory in the 3rd century bc. It was renowned  as the entranceway into China used by Marco Polo. Eastern Gansu is the  main site of earthquakes in China; in  1920 an earthquake there destroyed  many towns and caused 200,000  deaths. Wheat is the province�s chief  crop, and wheat flour rather than rice  is the basis of the local diet.</p><p>Ganymede In Greek legend, the  son of King Tros (or Laomedon) of  Troy. Because of his unusual beauty,  he was carried off by Zeus disguised  as an eagle, and he became cup�  bearer to the gods.

When Shihuangdi, emperor of  the Qin dynasty, died in 210 bc, Liu joined the rebels led by Xiang Yu in  an effort to overthrow the Qin. Xiang Yu triumphed and rewarded Liu  with the kingdom of Han in western China, but the two allies subsequently  turned against each other. Liu�s pragmatic shrewdness triumphed over  Xiang Yu�s aristocratic naivete, and, taking the name Gaozu, he became  the Han dynasty�s first ruler.</p><p>gar Any of several large North or Central American fishes of the genus  Lepisosteus. They are related to the bowfin and date back to the Eocene  Epoch. Gars are confined chiefly to fresh water, though some species enter  brackish or salt water. They frequently bask at the surface in sluggish  waters and commonly breathe atmospheric air. Their jaws and face form  a sharp-toothed beak, and their body is encased in an armour of diamond�  shaped, thick scales. Their eggs are toxic to predators. They are highly  voracious predators, with long rows of needlelike teeth. The alligator gar  of the southern U.S. reaches a length of about 10 ft (3 m) and is one of  the largest freshwater fishes.</p><p>Garand \go-'rand, 'gar-ond\, John C(antius) (b.

From 1919 he worked as a civilian employee at the Springfield  Armory. There he devised a gas-operated weapon that was 43 in. (109  cm) long yet weighed only 9.5 lbs (4.3 kg). Adopted in 1936 as the U.S.  Rifle, Caliber .30 Ml, the Garand rifle became the world�s first standard-  issue autoloading infantry rifle. It gave U.S. troops in World War II such  an advantage in firepower that George Patton called it �the greatest battle  implement ever devised.� More than five million Mis were manufactured  before it was phased out in 1957.

Garcia  Lorca studied literature, painting, and music and later was a founder,  director, and musician for La Barraca, a theatrical company that brought  classical drama to rural audiences. He was an established experimental  poet when he became famous for The Gypsy Ballads (1928), a verse col�  lection lyrically combining his musical, poetical, and spiritual impulses;  as in many of his later works, its themes and images were drawn from  folk traditions. Of his many poems of death, �Lament for the Death of a  Bullfighter� (1935), written for a friend, is his most famous poem and the  finest elegy in modern Spanish literature. His dramatic trilogy consisting</p><p>of Blood Wedding (produced 1933), Yerma (produced 1934), and The  House of Bernarda Alba (produced 1936) is the best known of his mas�  terpieces.

Largest  of the Italian lakes, it is 34 mi (54 km) long and 2 to 11 mi (3 to 18 km)  wide, with a shoreline of 77.5 mi (125 km). It borders Lombardy, Veneto,  and Trentino-Alto Adige. Separated from the Adige River valley by the nar�  row ridge of Mount Baldo, it is fed by the Sarca River at its northern end,  while the Mincio flows out toward the Po River to the south. The lake is  encircled by the Gardesana scenic route, opened in 1931. Well sheltered  by the Alps to the north, Lake Garda has a temperate Mediterranean cli�  mate. It is a popular resort area.</p><p>garden Plot of ground where herbs, fruits, flowers, vegetables, or trees  are cultivated. The earliest surviving detailed garden plan is Egyptian and  dates from about 1400 bc; it shows tree-lined avenues and rectangular  ponds. Mesopotamian gardens were places where shade and cool water  could be enjoyed; Hellenistic gardens were conspicuously luxurious in  their display of precious materials, a tradition carried over by Byzantine  gardens. Islamic gardens made use of water, often in pools and fed by  narrow canals resembling irrigation channels. In Renaissance Europe, gar�  dens reflected confidence in human ability to impose order on the exter�  nal world; Italian gardens emphasized the unity of house and garden.  French 17th-century gardens were rigidly symmetrical, and French cul�  tural dominance in Europe popularized this style into the next century. In  18th-century England, increasing awareness of the natural world led to  the development of �natural� gardens that made use of irregular, nonsym-  metrical layouts. Chinese gardens have generally harmonized with the  natural landscape, and have employed rocks gathered from great distances  as a universal decorative feature. Early Japanese gardens imitated Chi�  nese principles; later developments were the abstract garden, which might  feature only sand and rocks, and miniature gardens made in trays (see  bonsai).</p><p>garden city Ideal planned community as envisioned by the British town  planner Ebenezer Howard (1850-1928).

At the center would be a garden ringed with a civic and  cultural complex, a park, housing, and industry, the whole surrounded by  an agricultural green belt. Traffic would move along radial avenues and  ring roads. The first garden city was built at Letchworth, England, in 1903.  Though Howard�s ideas have been widely influential, imitators have often  ignored his stipulation that the town be a self-contained, true mixed-use  community.</p><p>Garden Grove City (pop., 2000: 165,196), southwestern California,  U.S. Located south of Anaheim, it is a growing suburban residential area.

Though palatial gar�  dens existed in ancient times, small home gardens became prevalent only  in the 19th century. Gardening as a pastime grew with the increase in  home ownership and leisure time. A well-designed flower garden displays  blends and contrasts of colours and forms, and it takes into account the  effect of seasonal changes. Essential tasks include soil maintenance, water  regulation, control of weeds, and protection of plants from pests and dis�  eases. Though chemical fertilizers, pesticides, and herbicides are widely  used, less-toxic organic supplements and pest controls, predatory insects,  and hand-weeding have become increasingly popular.</p><p>Gardiner, Samuel Rawson (b.

He taught at King�s College, London, and was a fellow at Oxford. His  researches among manuscript collections gave unrivaled authority to his  monumental undertaking. Its principal volumes were History of England  from the Accession of James I to the Outbreak of the Civil War, 1603-  1642 (1883-84); History of the Great Civil War, 1642-1649 (1886, 1893);  and History of the Commonwealth and Protectorate, 1649-1660 (1903).</p><p>Gardner, Alexander (b.

Brady as a  portrait photographer, and within two years he opened a studio for Brady  in Washington, D.C. In 1861 he began to assist Brady in making a pho�  tographic record of the American Civil War. Brady refused to give him  public credit, so in 1863 he opened his own portrait studio and continued  photographing the war on his own. He published a collection of 100  original prints in 1866. From 1867, as photographer for the Union Pacific  Railroad in Kansas, he chronicled the building of the railroad and the new  settlements built around it.</p><p>Gardner, Ava (Lavinia) (b.

Bom to a tenant farmer,  she appeared in minor film parts until her role in The Killers (1946) made  her a star. She played temptresses and seductive heroines in films such  as One Touch of Venus (1948), Show Boat (1951), The Snows of Kiliman�  jaro (1952), and The Barefoot Contessa (1954). A sensuous, dark-haired  beauty, she was praised for her powerful and touching performances in  films such as Mogambo (1953), On the Beach (1959), and The Night of  the Iguana (1964).</p><p>Gardner, Erie Stanley (b.

He dropped  out of college and was admitted to the California bar after three years as  a law-firm typist. While practicing trial law, he wrote pulp fiction, basing  the courtroom scenes and brilliant legal maneuvers on his own tactics. He  gave up law following the success in 1933 of The Case of the Velvet Claws  and The Case of the Sulky Girl, his first novels featuring the lawyer-  detective Perry Mason. Eighty Perry Mason novels followed. He also  wrote two other series of detective stories, one under the pseudonym A. A.  Fair.</p><p>Garfield, Janies A(bram) (b.

He attended Western Reserve</p><p>Eclectic Institute (later Hiram Col�  lege) at Hiram, Ohio, and graduated  (1856) from Williams College. He  returned to the Eclectic Institute as a  professor of ancient languages and in  1857, at age 25, became the school�s  president. In the American Civil War  he led the 42nd Ohio Volunteers and  fought at Shiloh and Chickamauga.</p><p>He resigned as a major general to  serve in the U.S. House of Represen�  tatives (1863-80). As a Radical Repub�  lican, he sought a firm policy of  Reconstruction in the South. In 1876  he served on the Electoral Commis�  sion that decided the presidential  election between Rutherford B. Hayes  and Samuel Tilden. He was House  Republican leader from 1876 to  1880, when he was elected to the  Senate by the Ohio legislature. At the  1880 Republican nominating con�  vention, the delegates supporting Ulysses S. Grant and James Blaine became  deadlocked. On the 36th ballot, Garfield was nominated as a compromise  presidential candidate, with Chester Arthur as vice president; they won  the election by a narrow margin. His brief term, lasting less than 150 days,  was marked by a dispute with Sen. Roscoe Conkling over patronage. On  July 2 he was shot at Washington�s railroad station by Charles J. Guiteau,  a disappointed office seeker. He died on Sept. 19 after 11 weeks of pub�  lic debate over the ambiguous constitutional conditions for presidential  succession (later clarified by the 20th and 25th Amendments).</p><p>Garfunkel, Art See Paul Simon</p><p>Gargano \gar-'ga-no\ Promontory ancient Garganum Moun�  tainous promontory jutting into the Adriatic Sea from eastern coast of  Italy.

He came under the influence of Giuseppe Mazzini in 1834,  took part in a failed mutiny intended to provoke a republican revolution  in Piedmont, and escaped to France. He lived in exile in South America  (1836-48) and learned guerrilla warfare tactics during liberation attempts  in Brazil and Uruguay. He returned to Italy in 1848 with his small band  of �Red Shirts� and fought in Milan in the war of independence against  Austria. After Pope Pius IX fled Rome (1848), Garibaldi for a while  defended the city from the French when they attempted to reinstate papal  rule. His bold retreat through central Italy made him a well-known fig�  ure. He lived in exile again until 1854, and in 1859 he led an army in  another war against Austria.

He joined the American Anti-Slavery Society and agitated for emancipa�  tion; in a 1843 speech at a national convention of freedmen he called on  slaves to revolt and murder their masters. The convention refused to  endorse his radicalism, and he gradually turned more toward religion,  serving as pastor in a number of Presbyterian pulpits during the next two  decades.

In diverse roles in plays such as King Lear, Hamlet, and Ben Jonson�s  The Alchemist, he was acclaimed for his naturalistic style and came to be  regarded as one of England�s greatest actors. As part owner and manager  of the Drury Lane Theatre (1747-76) he made it London�s most prosper�  ous theatre, reformed theatrical stage practices, and replaced many Res�  toration adaptations of Shakespeare with his own versions.

In 1833 he  helped found the American Anti-  Slavery Society. In 1837 he  renounced church and state and  embraced the doctrines of Christian  �perfectionism,� which combined  abolition, women�s rights, and non-  resistance with the biblical injunc�  tion to �come out� from a corrupt  society by refusing to obey its laws  and support its institutions. His radi�  cal blend of pacifism and anarchism precipitated a crisis in the Anti-  Slavery Society, a majority of whose members chose to secede when he  and his followers voted a series of resolutions admitting women (1840).  In the two decades between the schism of 1840 and the American Civil  War, Garrison�s influence waned as his radicalism increased. Through  The Liberator he denounced the Compromise of 1850, the Kansas-  Nebraska Act, and the Dred Scott decision and hailed John Brown�s raid.  During the Civil War he forswore pacifism to support Pres. Abraham Lin�  coln and welcomed the Emancipation Proclamation.

The sample of gas or vola�  tile liquid to be analyzed is injected into the inlet; its components move  through with a carrier gas (usually hydrogen, helium, or argon) at rates  influenced by their degree of interaction with the stationary phase. The  temperature, nature of the stationary phase, and column length can be  varied to improve separation. The gas stream issuing from the column�s  end may pass through a thermal conductivity detector or a flame ioniza�  tion detector, where its properties are compared with those of known ref�  erence substances. GC is used to measure air pollutants, essential oils,  gases or alcohol in blood, and composition of industrial process streams.</p><p>gas laws Laws that relate the pressure, volume, and temperature of a gas.  Boyle�s law�named for Robert Boyle �states that, at constant tempera�  ture, the pressure P of a gas varies inversely with its volume V, or PV =  k, where k is a constant. Charles�s law�named for J.-A.-C. Charles  (1746-1823)�states that, at constant pressure, the volume V of a gas is  directly proportional to its absolute (Kelvin) temperature T, or V/T = k.  These two laws can be combined to form a single generalization of the  behaviour of gases known as an equation of state, PV = nRT, where n is  the number of gram-moles of a gas and R is called the universal gas con�  stant. Though this law describes the behaviour of an ideal gas, it closely  approximates the behaviour of real gases.

The  reservoir rock must be permeable and porous to contain the gas, and it  has to be capped by impervious rock in order to form an effective seal  and prevent the gas from escaping. Typical reservoir rocks are sedimen�  tary and include sands, sandstones, arkoses, and fissured limestones and  dolomites. In the U.S. and certain other countries, artificial gas reservoirs  are being created from depleted oil and gas fields, particularly near salt  domes and in sedimentary basins, to store gas during periods of low con�  sumption for later use.</p><p>Gascony \'gas-ks-ne\ French Gascogne \ga-'skon y \ ancient Vasco-  nia Historical and cultural region, southwestern France. It encompasses  portions of the southwestern French regions of Aquitaine and Midi-  Pyrenees. Historically, it consisted of the northern foothills of the Pyrenees  and extended east from the Basque Country along the France-Spain bor�  der to Toulouse on the upper Garonne River. Under Roman rule it was the  province of Novempopulana. Taken by the Visigoths in the 5th century  and by the Franks in 507, it was overrun from 561 by the Basques, or  Vascones; in 602 the Frankish kings recognized Vasconia, or Gascony, as  a duchy. In 1052 it was conquered by Aquitaine, and in the 12th century  it passed to the Plantagenet kings of England.

Elizabeth  Cleghorn Stevenson known as  Mrs. Gaskell (b. Sept. 29, 1810,</p><p>Chelsea, London, Eng.�d. Nov. 12,</p><p>1865, near Alton, Hampshire) British  writer. The daughter of a Unitarian  minister, Gaskell also married a Uni�  tarian minister and began writing in  middle age. Cranford (1853), her  most popular novel, and the unfin�  ished Wives and Daughters (1864-  66), perhaps her best, are about the  lives of country villagers. Mary Bar�  ton (1848), Ruth (1853), and North</p><p>and South (1855) examine social problems of the urban working class. In  1857 she wrote the first biography of her friend Charlotte Bronte (see  Bronte sisters).</p><p>gasoline British petrol Mixture of volatile, flammable hydrocarbons  derived from petroleum, used as fuel for internal-combustion engines and as  a solvent for oils and fats. Gasoline became the preferred automobile fuel  because it releases a great deal of energy when burned, it mixed readily  with air in a carburetor, and it initially was cheap due to a large supply.  Costs have now increased greatly except where subsidized. Gasoline was  first produced by distillation. Later processes increased the yield from  crude oil by splitting large molecules into smaller ones. Still other meth�  ods, such as conversion of straight-chain hydrocarbons into their  branched-chain isomers, followed. The resulting gasoline is a complex  mixture of hundreds of hydrocarbons. A gasoline�s octane number indi�  cates its ability to resist knocking (premature combustion) and can be  altered by changing the proportions of certain components. The compound  tetraethyl lead, once used to reduce knocking, has been banned as toxic.  Other additives include detergents, antifreezes, and antioxidants. Since the  mid-20th century gasoline fumes have been recognized as a major com�  ponent of urban air pollution. Efforts to reduce dependence on gasoline,  which is a nonrenewable resource, include use of gasohol, a 9:1 mix of  gasoline and ethanol, and the development of electric automobiles.</p><p>gasoline engine Most widely used form of internal-combustion engine,  found in most automobiles and many other vehicles. Gasoline engines vary  significantly in size, weight per unit of power generated, and arrangement  of components. The principal type is the reciprocating-piston engine. In  four-stroke engines, each cycle requires four strokes of the piston�intake,  compression, power (expansion), and exhaust�and two revolutions of the  crankshaft. In a two-stroke cycle, the compression and power strokes of  the four-stroke cycle are carried out without the inlet and exhaust strokes,  in one upstroke and one downstroke of the piston and one revolution of  the crankshaft. The size, weight, and cost of the engine per horsepower  are therefore less, and two-stroke-cycle engines are used in motorcycles  and smaller machines (e.g., lawnmowers and power rakes).

It eliminates the cells that secrete acid and  halts the production of gastrin, the hormone that stimulates them. Once a  common operation, it is now a last resort. The usual procedure, antrec�  tomy, removes the lower half of the stomach (antrum), the chief site of  gastrin secretion. The remaining stomach is joined to the duodenum. Sub�  total gastrectomy removes up to three-quarters of the stomach.

Acute gastritis, usu�  ally caused by ingesting something irritating or by infection, starts sud�  denly, with severe pain, vomiting, thirst, and diarrhea, and subsides  rapidly. Treatment involves a short fast and then a bland diet, sedatives,  and antispasmodics. Chemical gastritis, from ingestion of corrosive  chemicals, requires emptying and washing out the stomach. Chronic gas�  tritis has vague symptoms, including abdominal discomfort or pain, poor  appetite, gas, and irregular bowel movements. Causes include prolonged  use of aspirin or other irritating drugs, infection with Helicobacter pylori,  and pernicious anemia. Treatment for chronic gastritis depends on the  cause.</p><p>gastroenteritis \ I ga-stro-,en-t3- , ri-t9s\ Acute infectious syndrome of  the stomach lining and intestines. Symptoms include diarrhea, vomiting,  and abdominal cramps. Severity varies from transient diarrhea to life-  threatening dehydration, children and the very old being more at risk for  the latter. Many microorganisms produce it, either by secreting toxins or  by invading the gut walls. Forms of gastroenteritis include food poison�  ing, cholera, and traveler�s diarrhea. Depending on cause and severity,  treatment includes antibiotics or simply supportive care.</p><p>gastroenterology V.ga-stro-.en-to-'ra-lo-jeX Medical specialty dealing  with digestion and the digestive system. In the 17th century Jan Baptista  van Helmont conducted the first scientific studies in the field; William  Beaumont published his own observations in 1833. Lavage (washing out  the stomach) and endoscopy were developed in the 19th century, and  endoscopy and X rays with a contrast medium were first used to visualize  the stomach and digestive organs in the 1890s.

Symptoms of GERD may include heartburn, coughing,  frequent clearing of the throat, and difficulty in swallowing. It can be  caused by relaxation of the muscle that connects the esophagus and the  stomach, delayed emptying of the esophagus or stomach, hiatal hernia,  obesity, or pregnancy. Treatment is with antacids or acid-inhibiting medi�  cations and lifestyle changes such as not eating before bedtime, avoiding  acidic or fatty foods or beverages, cessation of smoking, and weight loss.  Surgery may be necessary in severe cases.</p><p>gastronomy Art of selecting, preparing, serving, and enjoying fine  food. Two early centres of gastronomy were China (from the 5th century  bc) and Rome, the latter noted for the excess and ostentation of its ban�  quets. The foundations of modem Western gastronomy were laid during  the Renaissance, particularly in Italy and France. The influential grande  cuisine of France reached its apex in the works of Marie-Antoine Careme  and Auguste Escoffier. Regardless of regional differences in cuisine, a pri�  mary consideration in food preparation is freshness. Others include com�  plementarity or opposition of taste, contrast of textures, and overall  appearance, including colour harmony and accent.

Gastropods, which include the  snails, conchs, whelks, limpets, periwinkles, abalones, slugs, and sea slugs (see  nudibranch), are found worldwide, in marine, freshwater, and terrestrial  environments. Gastropods typically have a large foot with a flat sole for  crawling, a single coiled shell that covers the soft body, and a head that  bears a pair of eyes and tentacles. However, they are so diverse that some  forms lack shells, while animals in one genus have shells with two halves,  like bivalves. Most feed by using a radula, a ribbon of small horny teeth  that tear food into pieces. They may be herbivores, carnivores, predators,  parasites, or filter feeders of plankton and detritus.</p><p>Gates of the Arctic National Park National preserve, northern  Alaska, U.S. Its area of 11,756 sq mi (30,448 sq km) is entirely north of  the Arctic Circle.

In such works as Figures in Black  (1987) and The Signifying Monkey (1988) he has used the term signifyin�  to represent a practice that can link African and African American liter�  ary histories; his other books include Thirteen Ways of Looking at a Black  Man (1998). He has edited many anthologies, including Reading Black,  Reading Feminist (1990) and the Norton Anthology of African American  Writers (1997), and has restored and edited many lost works by black  writers.

April 10, 1806,  New York, N.Y., U.S.) English-born American general. He served in the  British army during the French and Indian War. In 1772 he immigrated  to Virginia, where he sided with colonial interests. He was made adjutant  general of the Continental Army (1775) and succeeded Gen. Philip Schuyler  in New York (1777). Assisted by Benedict Arnold, he forced the surren�  der of British forces under John Burgoyne at the Battle of Saratoga (1777).  Congress then chose Gates as president of the Board of War. Supporters,  including Thomas Conway, sought to have Gates replace George Wash�  ington, but the plan failed, and Gates returned to his New York command.  In 1780 he was transferred to the South, where he attempted to oust the  British forces under Charles Cornwallis but was defeated at the Battle of  Camden, S.C. An official inquiry was ordered, but charges never were  pressed. He retired to Virginia, then freed his slaves in 1790 and moved  to New York.</p><p>Gatling gun Hand-cranked multi barrel rotary gun. It was invented by  Richard J. Gatling (1818-1903) during the American Civil War.

The barrels were loaded by gravity and the action of the cartridge con�  tainer, and the spent cartridge cases were ejected. Without equal in the era  of single-shot guns, it could fire as many as 3,000 rounds per minute.

Though his early works were Mudejar (Span�  ish Muslim-Christian) in effect, his work after 1902 eluded all conven�  tion. He began to produce �equilibrated� structures able to stand on their  own without bracing; his system employed piers and columns that tilt to  transmit diagonal forces and thin-shell, laminated-tile vaults. Works such  as the Park Giiell (1900-14), Casa Mila (1905-10), and Casa Batllo  (1904-06) feature undulating surfaces and polychrome decoration (e.g.,  pieces of broken ceramic). Much of his later career was occupied with the  extraordinary church of the Holy Family (Sagrada Familia), still unfin�  ished at his death, in which he transformed the Gothic style into a com�  plex forest of flowing forms and exuberant detail, with spiral-shaped piers,  vaults, towers, and a hyperbolic paraboloid roof.</p><p>Gaugamela V.go-go-'me-bV Battle of (331 bc) Clash between the  forces of Alexander the Great and Darius III of Persia that brought the fall  of the Persian empire.

From c. 1872 to 1883  he was a successful stockbroker in Paris. He met Camille Pissarro about  1875, and he exhibited several times with the Impressionists. Disillusioned  with bourgeois materialism, in 1886 he moved to Pont-Aven, Brittany,  where he became the central figure of a group of artists known as the  Pont-Aven school. Gauguin coined the term �Synthetism� to describe his  style during this period, referring to the synthesis of his paintings� formal  elements with the idea or emotion they conveyed. Late in October 1888  Gauguin traveled to Arles, in the south of France, to stay with Vincent  van Gogh. The style of the two men�s work from this period has been  classified as Post-Impressionist because it shows an individual, personal  development of Impressionism�s use of colour, brushstroke, and nontra-  ditional subject matter. Increasingly focused on rejecting the materialism  of contemporary culture in favour of a more spiritual, unfettered lifestyle,  in 1891 he moved to Tahiti. His works became open protests against  materialism. He was an influential innovator; Fauvism owed much to his  use of colour, and he inspired Pablo Picasso and the development of Cub�  ism.</p><p>Gauhati See Guwahati</p><p>Gaul Latin Gallia Ancient country, Europe, located generally south and  west of the Rhine, west of the Alps, and north of the Pyrenees.

Supporters of gay rights seek to eliminate  sodomy laws barring homosexual acts between consenting adults and call  for an end to discrimination against gay men and lesbians in employment,  credit, lending, housing, marriage, adoption, public accommodations, and  other areas of life. The first group to campaign publicly was founded in  Berlin in 1897 by Magnus Hirschfeld (1868-1935) and had 25 local chap�  ters in Europe by 1922; suppressed by the Nazis, it did not survive World  War II. The first U.S. support group, the Mattachine Society, was founded  in Los Angeles c. 1950; the Daughters of Bilitis, for lesbians, was founded  in San Francisco in 1955. The Dutch Association for the Integration of  Homosexuality COC, founded as the COC (Cultuur en Ontspannings Cen�  trum [�Culture and Recreation Center�]) in 1946 and headquartered in  Amsterdam, is a prominent European group and the oldest existing gay  rights organization. Many date the expansion of the modern gay rights  movement to the Stonewall rebellion in New York City in 1969, when a  raid by police on a gay bar called the Stonewall Inn provoked a riot by  bar patrons. �Stonewall� came to be commemorated annually by the  observance of Gay and Lesbian Pride Week in cities around the world.  The International Lesbian and Gay Association (founded 1978), head�  quartered in Brussels, lobbies for human rights and opposes discrimina�  tion against homosexuals. Although the movement is strongest in western  Europe and North America, gay rights organizations exist in many coun�  tries throughout the world. Among the major issues pressed by gay rights  advocates in the 1990s and into the 21st century were the passage of hate  crime laws and the establishment of legal rights for homosexuals to marry,  adopt children, and serve openly in the military.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>742 I Gay &gt; GDP</p><p>Gay, John (b.

He signed a contract with Harvey Fuqua (b. 1924) in 1959 and  followed him to Motown, where he played drums on early Smokey Rob�  inson hits. His own hits (from 1962) climaxed in �I Heard It Through the  Grapevine� (1967). He paired with female singers, including Tammi Ter�  rell (1946-70), in songs by Nick Ashford (b. 1943) and Valerie Simpson  (b. 1948). With What�s Goin� On? (1971) his songs became more socially  conscious. Troubled in his personal relationships and finances, he  reemerged in 1982 with �Sexual Healing.� He was shot to death by his  father in a quarrel.</p><p>Gayomart \ l ga-yo-'mart\ In later Zoroastrianism, the first man and the  progenitor of humankind. Created by Ahura Mazda, he was made incar�  nate after 3,000 years of life as a spirit. His existence at first immobilized  Ahriman, the evil spirit who wanted to invade creation, but after 30 years  of attacks Ahriman destroyed Gayomart. His body became the earth�s  minerals; gold was his seed, and from it sprang the human race.</p><p>Gaza Strip Arabic Qita* Ghazzah \ke-'ta-'ga-z3\ Hebrew Rezu'at  Azza \re-zu-'at-'az-9\ Territory, southeastern Mediterranean Sea coast.  Occupying 140 sq mi (363 sq km) northeast of the Sinai Peninsula, it is  also the location of the city of Gaza, which has been a prosperous trad�  ing centre for much of its history and was first mentioned in the 15th cen�  tury bc. Often besieged by invaders, including Israelites, Assyrians,  Babylonians, and Persians, it declined in importance after the Crusades.  It was ruled by the Ottoman Empire from the 16th century. After World  War I (1914-18) the city and the strip became part of the British man�  date of Palestine. Following the first Arab-Israeli war (1948-49), the ter�  ritory was occupied by Egypt, and the city became that country�s  headquarters in Palestine. The occupied area was later reduced to an area  25 mi (40 km) long, which became known as the Gaza Strip, still under  Egyptian control. In the Six-Day War (1967) it was captured by Israel.  The area�s chief economic problem was the extreme poverty of the large  number of Palestinian Arab refugees living there. In 1987, rioting among  Gaza�s Palestinians marked the beginning of the first intifadah. Continued  unrest led in 1993 to an agreement between Israel and the Palestine Lib�</p><p>eration Organization granting limited self-rule to the Palestinian popula�  tion of the Gaza Strip and West Bank. A breakdown in further negotiations  in 2000 led to another outbreak of violence. In an attempt to stem the  fighting, Israel withdrew all its soldiers and settlers from the Gaza Strip  in 2005, and control of the territory was transferred to the Palestinians.</p><p>gazebo \g3-'ze-bo\ Lookout in the form of a turret, cupola (small, lan-  temlike dome), or garden house set on a height to give an extensive view.  Few late-18th- and 19th-century rustic gazebos survive, but 17th-century  turrets built up in an angle of the garden wall are not uncommon. The  term now often refers specifically to a freestanding roofed structure, typi�  cally octagonal, with open or latticework sides.</p><p>gazel See ghazel</p><p>gazelle Any of numerous species of graceful antelope (genus Gazella)  found on open plains and arid lands  from Mongolia to the Atlantic coast  of North Africa and throughout east�  ern and central tropical Africa.</p><p>Gazelles are 2-3 ft (60-90 cm) high  at the shoulder. They range in herds  that usually contain 5 to 10 individu�  als but may include several hundred.</p><p>They are generally brown with white  underparts and rump, and many have  a horizontal dark band along each  side. A light stripe runs down each  side of the face. The horns have  numerous raised rings and are vari�  ously shaped, but all are slightly  upturned at the ends. Some species  are considered endangered.</p><p>Gazelle Peninsula Peninsula, extending northeast from the island of  New Britain, Papua New Guinea. Located in the South Pacific Ocean, the  Gazelle Peninsula is about 50 mi (80 km) wide but tapers to 20 mi (32  km) where it joins the mainland. From coastal plains its surface rises to  7,999 ft (2,438 m) at Mount Sinewit in the central Baining Mountains.  The peninsula is volcanically active and highly fertile, with cocoa and  copra plantations along the coast. The area is the most populous portion  of New Britain and was the base of German settlement late in the 19th  century.</p><p>Gaziantep \,ga-ze-Sin-tep\formerly Aintab \In-'tab\ City (pop., 1997:  712,800), south-central Turkey. Located north of Aleppo, it was strategi�  cally situated near ancient trade routes and has been inhabited since the  early 4th millennium bc. Known as Hamtap, it was an important strong�  hold guarding the Syrian-Byzantine border. Captured by Turks in 1183,  it later changed hands among various invaders until its absorption into the  Ottoman Empire in the early 16th century. Called Aintab under the Otto�  mans, it was occupied by the British and French after World War I (1914-  18). By then it was a centre of Turkish nationalist resistance to European  occupation, and upon its return to Turkey in 1922 it was renamed in  honour of its heroic stand (Turkish gazi, �champion�).</p><p>Gdansk \go-'dansk\ German Danzig \'dant-sik\ City (pop., 2000 est.:  456,574), capital of Pomorskie province, northern Poland. Located at the  mouth of the Vistula River on the Baltic Sea, it was first mentioned in the  late 10th century as a Polish town. The capital of the dukes of Pomerania  in the 13th century, it was taken by the knights of the Teutonic Order in  1308. In 1466 Casimir IV regained the territory for Poland, and Gdansk  expanded greatly. From 1793 it was controlled mainly by Prussia; fol�  lowing World War I, it was a free city governed by Poland. In 1938 Adolf  Hitler demanded that Gdansk be given back to Germany; Poland�s refusal  was the excuse for his attack on Poland in 1939, which precipitated World  War II. The city, greatly damaged during the war, was returned to Poland  in 1945. It is now fully restored, with renewed port facilities. The inde�  pendent labour union Solidarity was founded there in 1980.</p><p>Gdansk, Gulf of Inlet of the Baltic Sea. Bordered by Poland on the  west and south and Russia on the east, it extends 40 mi (64 km) from  north to south and 60 mi (97 km) east to west, reaching a maximum depth  of more than 371 ft (113 m). Coastal activities include shipbuilding, fish�  ing, and the resort trade.</p><p>GDP See gross domestic product</p><p>John Gay, oil painting by William Aik-  man; in the Scottish National Portrait  Gallery, Edinburgh.</p><p>COURTESY OF THE SCOTTISH NATIONAL PORTRAIT  GALLERY, EDINBURGH</p><p>Thomson's gazelle (Gazella thomsoni).</p><p>E.R.

Gears operate in pairs, the teeth of one engaging the teeth  of a second, to transmit and modify rotary motion and torque. To trans�  mit motion smoothly, the contacting surfaces of gear teeth must be care�  fully shaped to a specific profile. The smaller of a gear pair is often known  as the pinion. If the pinion is on the driving shaft, the pair acts to reduce  speed and to amplify torque; if the pinion is on the driven shaft, the pair  acts to increase speed and reduce torque.</p><p>Geb \'geb\ or Keb In ancient Egyptian religion, the god of the earth and  the physical support of the world. Geb and his sister Nut belonged to the  second generation of deities at Heliopolis. In Egyptian art he was often  depicted as lying at the feet of the air god, Shu, with Nut, the sky god�  dess, arched above them. He was the third divine ruler among the gods,  and the pharaohs claimed descent from him.</p><p>gecko Any of about 750 species of harmless but noisy lizards in the  family Gekkonidae: small, usually nocturnal reptiles that have soft skin,  a short, stout body, a large head, and weak limbs often equipped with  suction-padded digits. The pads contain tiny hairlike projections that cling  to surfaces, allowing geckos to climb absolutely smooth and vertical sur�  faces and even to run across ceilings. Most are 1-6 in. (3-15 cm) long,  including the tail, and they are usually drably coloured, with gray, brown,  or white predominating. They live in habitats ranging from deserts to  rainforests in warm areas worldwide. Where kept as pets in houses or  apartments, they are allowed to run free and eat undesirable insects.</p><p>Gedrosia Xyo-'dro-zhoN Historic region, South Asia. It was located west  of the Indus River, in what is now the Balochistan region of Pakistan. In  325 bc Alexander the Great�s forces suffered disastrous losses there as they  returned from India. They captured the area, but after Alexander�s death  his general Seleucus I Nicator was forced to make peace by trading Gedro�  sia and all his territories east of the Hindu Kush for 500 elephants. His  departure ended Greek intervention on the subcontinent of India.</p><p>Geertgen tot Sint Jans Vgart-gon-tot-sint-'yansV (fl. c. 1475-1495,  Netherlands, Hapsburg empire) Dutch painter. Little is known of his  career. His name means �Little Gerard of the Brethren of St. John,� after  the religious order in Haarlem of which he was a lay brother. His only  documented work, the large triptych The Crucifixion, was painted for the  Brethren�s monastery. Paintings attributed to him include a luminous noc�  turnal Nativity and St. John the Baptist in the Wilderness.</p><p>Geertz VgortsV, Clifford (James) (b. Aug. 23, 1926, San Francisco,  Calif., U.S.) U.S. cultural anthropologist, a leading proponent of a form  of anthropology that stresses the importance of symbols and interpretation  in human social life. Culture, according to Geertz, is �a system of inher�  ited conceptions expressed in symbolic forms��forms that serve to  impose meaning on the world and make it understandable. Geertz�s writ�  ings have been influential both within and outside of anthropology; they  include The Religion of Java (1960), The Interpretation of Cultures  (1973), Local Knowledge (1983), and Works and Lives (1988). He referred  to his ethnographic methodology as �thick description.� Geertz taught at  the University of Chicago (1960-70), among other institutions, and in  1970 joined the Institute for Advanced Study in Princeton, N.J., becom�  ing an emeritus professor in 2000.

A strong  supporter of Charles Darwin�s theory of evolution, he showed that com�  parative anatomy supplies evidence of it. His Elements of Comparative  Anatomy (1859) stressed that structural similarities in different animals,  especially parts with a common origin (e.g., human arm, horse�s foreleg,  and bird�s wing), give clues to their evolutionary history.</p><p>gegenschein Vga-gon-.shlfo or counterglow Oval patch of faint  light exactly opposite the Sun in the night sky, so faint it can be seen only  in the absence of moonlight, away from city lights, with the eyes adapted</p><p>to darkness. It is lost in the light of the Milky Way except in February,  March, April, August, September, and October. The gegenschein and the  zodiacal light form the most notable parts of a band of very faint light  along the ecliptic. Both phenomena are thought to be the result of the  reflection of sunlight from interplanetary dust grains.</p><p>Gehrig Vger-igV (Henry) Lou(is) (b. June 19, 1903, New York, N.Y.,  U.S.�d. June 2, 1941, New York)</p><p>U.S. baseball player, one of the  game�s great hitters. Gehrig attended  Columbia University before joining  the New York Yankees. From 1925  to 1939 the left-handed first baseman  played in a record 2,130 consecutive  games. He earned the nickname �the  Iron Horse� long before this streak  was over; Gehrig�s record was not  broken until 1995 (see Cal Ripken). In  1932 Gehrig became the first player  to hit four home runs in a single  game, and he batted in 150 or more  runs in a season seven times. In 1939  his physical abilities had begun to  deteriorate and he took himself out  of the lineup; he was diagnosed with  AMYOTROPHIC LATERAL SCLEROSIS, which  came to be known as Lou Gehrig�s  disease. He left baseball with a  career batting average of .340 and  493 home runs. His 1,990 runs bat�  ted in place him third in history,  behind Hank Aaron and Babe Ruth.</p><p>On July 4, 1939, more than 60,000 Yankee fans turned out to recognize  Gehrig�s achievements and heard him deliver a speech in which he  claimed to be the �luckiest man on the face of the earth.� Gehrig was the  first player to have his number (4) retired by his team.</p><p>Gehry \'ger-e\, Frank O(wen) (b. Feb. 28, 1929, Toronto, Ont., Can.)  Canadian-born U.S architect. He studied at the University of Southern  California and Harvard University. In his early buildings, his use of inex�  pensive materials (chain-link fencing, plywood, corrugated steel) gave  many of his projects an unfinished, whimsical air. His structures are often  characterized by unconventional or distorted shapes that have a sculptural,  fragmented, or collagelike quality. In designing public buildings, he tends  to cluster small units within a larger space rather than creating monolithic  structures, thus emphasizing human scale. Of particular note is his  Guggenheim Museum Bilbao (1991-97) in Spain, a shimmering pile of  sharply twisting, curving shapes surfaced in titanium. Gehry won the  Pritzker Architecture Prize in 1989.</p><p>Geiger Vgl-gorX, Abraham (b. May 24, 1810, Frankfurt am Main,  Ger.�d. Oct. 23, 1874, Berlin) German Jewish theologian. He served as  rabbi in Wiesbaden from 1832 and in Breslau 1838-63. He helped found  a theological journal in 1835 and served as its editor. Geiger urged the  need for simplified ritual, liturgy in one�s native language, and emphasis  on the prophetic writings as the core of Judaism, and he stressed the pro�  cess of change and growth in Jewish religious consciousness, a basic idea  in Reform Judaism.</p><p>Geiger Vgl-g3r\, Theodor Julius (b.

An early critic of the Nazis,  Geiger fled to Copenhagen, where in 1938 at the University of Arhus he  became Denmark�s first professor of sociology. He studied social strati�  fication and mobility, examining Danish intellectuals and the people of  Arhus. His posthumous Democracy Without Dogma (1964) expressed his  vision of a society depersonalized by ideology but redeemed by human  relationships.</p><p>Geisel Vgl-zoL, Theodor Seuss known as Dr. Seuss (b.

Invented by the  German physicist Hans Geiger (1882-1945) and later refined with help  from Walther Muller, the device is a gas-filled metal tube with a wire  through its axis and a high voltage applied to the wire. As particles enter  the tube, they create a large avalanche of ionization in the gas, which then  discharges, creating a brief electric pulse. The tube produces the same  large output pulse for virtually every charged particle that passes through  the gas and so is useful for detecting individual particles. It can therefore  indicate lower levels of radiation than is possible with other types of  detectors.</p><p>geisha Yga-shsN Member of a professional class of women in Japan  whose traditional occupation is to entertain men. A geisha must be adept  at singing, dancing, and playing traditional musical instruments (e.g., the  samisen) in addition to being skilled at making conversation. The geisha  system is thought to have emerged in the 17th century to provide a class  of well-trained entertainers set apart from courtesans and prostitutes:  though geisha sometimes had sexual relationships with their clients, they  were supposed to entertain primarily through their accomplishments. The  numbers of geisha have declined from some 80,000 in the 1920s to a few  thousand at present, almost all in the Tokyo and Kyoto areas, where they  are patronized by only the wealthiest businessmen and most influential  politicians. Ordinary businessmen seek out bar hostesses, who, though not  trained in traditional singing or dance, like geisha excel at supportive  conversation.</p><p>Gelasius \j9-'la-she-3s\ \, Saint (b. probably Africa�d.

He main�  tained papal authority and established Roman primacy in ecclesiastical  affairs. He is known for his theory of the two powers of world gover�  nance in which he asserted that both sacred and civil power are of divine  origin and independent. In 494 he changed the pagan Lupercalia festival  into the feast of the Purification.</p><p>gelatin Vje-l9-t 9 n\ Animal protein substance having gel-forming prop�  erties, used primarily in food products. Derived from collagen, it is  extracted by boiling animal skin and bones. It is commonly produced as  granules or as a mix with added sugars, flavours, and colours. Immersed  in a liquid, gelatin takes up moisture and swells, causing the mixture to  solidify. It is used to make such foods as molded desserts, jellied meats,  soups, candies, and aspics and to stabilize such emulsion and foam food  products as ice cream and marshmallows. It is nutritionally an incomplete  protein. It is also used in various pharmaceutical products.</p><p>Gelibolu See Gallipoli</p><p>Gell-Mann Vgel-.manV Murray (b. Sept. 15, 1929, New York, N.Y.,  U.S.) U.S. physicist. He entered Yale University at 15 and earned his  Ph.D. from the Massachusetts Institute of Technology in 1951. From 1955  he taught at the California Institute of Technology, becoming Millikan  professor of theoretical physics in 1967. In 1953 he introduced the con�  cept of �strangeness,� a quantum property that accounted for decay pat�  terns of certain mesons. In 1961 he and Yuval Ne�eman (b. 1925) proposed  a scheme (the �Eightfold Way�) that grouped mesons and baryons into  multiplets of 1, 8, 10, or 27 members on the basis of various properties.  He speculated that it was possible to explain certain properties of known  particles in terms of even more fundamental particles, or building blocks,  which he later called quarks. He was awarded a 1969 Nobel Prize.</p><p>Geltzer Vgyelt-syir\, Yekaterina (Vasilyevna) (b. Nov. 14, 1876,  Moscow, Russia�d. Dec. 12, 1962, Moscow) Russian prima ballerina of  the Bolshoi Ballet. She graduated from the Bolshoi Theatre�s ballet school  in 1894 and joined the company, becoming prima ballerina in 1901. She  was known for dramatic roles, including that of the heroine of The Red  Poppy (1927), in a career that lasted more than 40 years.

Stories of the  rise and fall of the two families, with their Buddhist overtones of eva�  nescence and their sense of heroic tragedy, have a popularity in Japan  akin to that of Arthurian legends in English-speaking countries.</p><p>gemstone Any of various minerals prized for beauty, durability, and  rarity. A few noncrystalline materials of organic origin (e.g., pearl, red  coral, and amber) also are classified as gemstones. Of the more than 3,500  identified natural minerals, fewer than 100 are used as gemstones and only  16 have achieved importance: beryl, chrysoberyl, corundum, diamond,  feldspar, garnet, jade, lazurite, olivine, opal, quartz, spinel, topaz, tour�  maline, turquoise, and zircon. Some of these (e.g., beryl and corundum)  provide more than one type of gem. In virtually all cases, the minerals  have to be cut and polished for use in jewelry.

Gender marking may be natural, with linguistic mark�  ers of gender corresponding to real-world gender, or purely grammatical,  with markers of gender in part semantically based and in part semanti�  cally arbitrary. In languages with grammatical gender, nouns are parti�  tioned into sets. Membership of a noun in a set may be expressed by its  form and/or by the forms of other parts of speech controlled by the noun.  Closely related to gender systems in language are class systems, as in  Bantu languages, in which the number of sets into which nouns are par-</p><p>Gemini, illumination from a Book of  Hours, Italian, c. 1475; in the Pierpont  Morgan Library, New York City.</p><p>COURTESY OF THE PIERPONT MORGAN LIBRARY, NEW  YORK, THE GLAZIER COLLECTION</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>gender gap &#x25BA; General Mills I 745</p><p>titioned is much larger, with distinct categories for things such as plants,  animals, and tools, though, as with nouns in Romance and Germanic lan�  guages, assignment of most nouns to classes is semantically arbitrary.</p><p>gender gap Difference in opinions or attitudes between men and  women concerning a variety of public and private issues, including politi�  cal candidates, parties, or programs. Until the 1980s men and women in  the U.S. exhibited similar voting habits. Since then, however, women have  been more likely than men to support the Democratic Party and liberal  policies, particularly on issues such as equal employment opportunity,  child care, and gun control. In contrast, in western Europe women his�  torically have been more likely than men to support conservative politi�  cal parties.</p><p>gene Unit of heredity that occupies a fixed position on a chromosome.  Genes achieve their effects by directing protein synthesis. They are com�  posed of DNA, except in some viruses that contain RNA instead. The  sequence of nitrogenous bases along a strand of DNA determines the  genetic code. When the product of a particular gene is needed, the portion  of the DNA molecule that contains that gene splits, and a complementary  strand of RNA, called messenger RNA (mRNA), forms and then passes  to ribosomes, where proteins are synthesized. A second type of RNA,  transfer RNA (tRNA), matches up the mRNA with specific amino acids,  which combine in series to form polypeptide chains, the building blocks  of proteins. Experiments have shown that many of the genes within a cell  are inactive much or even all of the time, but they can be switched on and  off. Mutations occur when the number or order of bases in a gene is dis�  rupted.

The introduction of new char�  acteristics through gene flow increases variability within the population  and makes possible new combinations of traits. In humans, gene flow  usually comes about through human migration.</p><p>gene therapy or gene transfer therapy Introduction of a nor�  mal gene into an individual in whom that gene is not functioning, either  into those tissue cells that normally express the gene (curing that indi�  vidual only) or into an early embryonic cell (curing the individual and all  future offspring). Prerequisites for each procedure include finding the best  delivery system (often a virus) for the gene, demonstrating that the trans�  ferred gene can express itself in the host cell, and establishing that the  procedure is safe.

It is found in most parts  of the world and is international in scope. Originally concerned with trac�  ing royal, aristocratic, or clerical lines, genealogy has broadened its scope  over the centuries, and many ordinary people now pursue it as a hobby.  In preliterate cultures genealogical information was transmitted orally,  usually as a list of names; later generations recorded this information.  Divine origins were often ascribed to kings and heroes. Modem genealo�  gists use artifacts, including ancient records, coins, deeds, tapestries,  paintings, and monuments, to help them in their work.</p><p>Genee, Dame Adeline orig. Anina Margarete Kirstina Petra  Jensen (b. Jan. 6, 1878, Hinnerup, Den.�d. April 23, 1970, Esher, Sur�  rey, Eng.) Danish-bom British dancer, choreographer, and teacher.

Originally signed by 23  countries at Geneva in 1947, GATT became the most effective instrument  in the massive expansion of world trade in the later 20th century. By 1995,  when GATT was replaced by the World Trade Organization (WTO), 125  nations had signed its agreements, which governed 90% of world trade.  GATT�s most important principle was trade without discrimination, in  which member nations opened their markets equally to one another. Once  a country and its largest trading partners agreed to reduce a tariff, that  tariff cut was automatically extended to all GATT members. GATT also  established uniform customs regulations and sought to eliminate import  quotas. It sponsored many treaties that reduced tariffs, the last of which,  signed in Uruguay in 1994, established the WTO.</p><p>General Dynamics Corp. Major U.S. defense contractor.

His first novel, Our Lady of the Flowers (1944), portrays an underworld  of thugs, pimps, and hustlers. Miracle of the Rose (1945-46) is based on  his adolescence at a notorious reform school, and The Thief�s Journal  (1949) recounts his life as a tramp, pickpocket, and prostitute. He became  a leading figure in avant-garde theatre with such plays as The Maids  (1947), The Balcony (1956), and The Blacks (1958), stylized Expression�  ist dramas designed to shock and implicate an audience by revealing its  hypocrisy and complicity in an exploitative social order.

In larger populations, any specific allele is  carried by so many individuals that it is almost certain to be transmitted by  some of them unless it is biologically unfavourable.</p><p>genetic engineering Artificial manipulation, modification, and  recombination of DNA or other nucleic-acid molecules in order to modify an  organism or population of organisms. The term initially meant any of a  wide range of techniques for modifying or manipulating organisms through  heredity and reproduction. Now the term denotes the narrower field of  recombinant-DNA technology, or gene cloning, in which DNA molecules  from two or more sources are combined, either within cells or in test tubes,  and then inserted into host organisms in which they are able to reproduce.  This technique is used to produce new genetic combinations that are of  value to science, medicine, agriculture, or industry. Through recombinant-  DNA techniques, bacteria have been created that are capable of synthesiz�  ing human insulin, human interferon, human growth hormone, a  hepatitis-B vaccine, and other medically useful substances. Recombinant-  DNA techniques, combined with the development of a technique for pro�  ducing antibodies in great quantity, have made an impact on medical  diagnosis and cancer research. Plants have been genetically adjusted to per�  form nitrogen fixation and to produce their own pesticides. Bacteria  capable of biodegrading oil have been produced for use in oil-spill clean�  ups. Genetic engineering also introduces the fear of adverse genetic  manipulations and their consequences (e.g., antibiotic-resistant bacteria or  new strains of disease). See also biotechnology, molecular biology.</p><p>genetics Study of heredity in general and of genes in particular. Modern  genetics began with the work of Gregor Mendel, who formulated the basic  concepts of heredity. Walter S. Sutton proposed that chromosomes were  the site of Mendel�s hereditary factors. The Hardy-Weinberg law estab�  lished the mathematical basis for studying heredity in populations. Tho�  mas Hunt Morgan provided evidence that genes occur on chromosomes  and that adjacent genes on the same chromosome form linkage groups.  Oswald Avery showed that DNA is the chromosome component that car�  ries genetic information. DNA�s molecular structure was deduced by  James D. Watson and Francis Crick. These and other developments led to  the deciphering of the genetic code of the DNA molecule, which in turn  made possible the recombination techniques of genetic engineering. An  understanding of genetics is necessary for the diagnosis, prevention, and  treatment of hereditary diseases, the breeding of plants and animals, and  the development of industrial processes that use microorganisms.

In the  16th century John Calvin transformed Geneva into a theocratic state and  the intellectual centre of Protestant Europe. In the 18th century, as the  birthplace of Jean-Jacques Rousseau and the sanctuary of Voltaire, it  attracted the elite of the Enlightenment. It joined the Swiss Confederation  in 1814. It was the site of the Geneva Convention in 1864, and the League  of Nations was founded there in 1919.

The first convention was ini�  tiated by Jean-Henri Dunant; it established that medical facilities were not  to be war targets, that hospitals should treat all wounded impartially, that  civilians aiding the wounded should be protected, and that the Red Cross  symbol should serve to identify those covered by the agreement. The sec�  ond convention amended and extended the first. The third stated that pris�  oners of war should be treated humanely and that prison camps should  be open to inspection by neutral countries. The 1949 conventions made  further provisions for civilians falling into a belligerent�s hands. Guerrilla  combatants were extended protection in two 1977 amendments, which the  U.S. did not sign.

The leader of a destitute clan, Temujin  fought various rival clans and formed a Mongol confederacy, which in  1206 acknowledged him as Genghis Khan (�Universal Ruler�). By that  year the united Mongols were ready to move out beyond the steppe. He  adapted his method of warfare, moving from depending solely on cavalry  to using sieges, catapults, ladders, and other equipment and techniques  suitable for the capture and destruction of cities. In less than 10 years he  took over most of Juchen-controlled China; he then destroyed the Mus�  lim Khwarezm-Shah dynasty while his generals raided Iran and Russia. He  is infamous for slaughtering the entire populations of cities and destroy�  ing fields and irrigation systems but admired for his military brilliance  and ability to learn.

In 1946 the UN General Assembly  declared genocide a punishable crime. By this declaration, genocide by  definition may be committed by an individual, group, or government,  against one�s own people or another, in peacetime or in wartime. This last  point distinguishes genocide from �crimes against humanity,� whose legal  definition specifies wartime. Suspects may be tried by a court in the coun�  try where the act was committed or by an international court (see Inter�  national Criminal Court).

In 1409 he was commissioned to decorate the Doges� Palace in Venice  with historical frescoes, now lost. His most important fresco cycle, also  destroyed, was in the church of St. John Lateran in Rome. His major sur�  viving painting is the celebrated Strozzi Altarpiece (1423), featuring The  Adoration of the Magi. Its combination of naturalism and rich ornamen�  tation influenced Italian artists throughout the century, notably Fra  Angelico and Benozzo Gozzoli, and established Gentile as one of Italy�s  greatest proponents of the International Gothic style.

She was raped by Tassi, and,  when he did not fulfill his promise to marry her, Orazio Gentileschi  brought him to trial in 1612. During that event she herself was forced to  give evidence under torture. In 1616 she joined the Academy of Design  in Florence and began to develop a powerful style of her own. She was  one of the greatest of Caravaggio�s followers in the Baroque style.  Although her compositions were graceful, her subject matter was often  violent; she illustrated such subjects as the story from the Apocrypha of  Judith, the Jewish heroine, beheading Holofemes, an invading general.  She worked in Rome and Naples and spent three years with her father in  London (1638�41). The first woman artist to attain an international repu�  tation, she is admired today as the earliest to show a feminist conscious�  ness in her work.</p><p>Gentileschi, Orazio orig.

His paintings of the early  17th century reveal the influence of Caravaggio�s strong chiaroscuro and  contemporary figure types; though more refined than Caravaggio�s works,  they lack the master�s power and uncompromising realism. Invited to  England by Charles I in 1626, he remained there as court painter the rest  of his life. Artemisia Gentileschi was his daughter.

The genus name,  capitalized and usually italicized, is the first word of a scientific name in  the system of binomial nomenclature.</p><p>geochemical cycle Developmental path followed by individual ele�  ments or groups of elements in the crustal and subcrustal zones of the  Earth and on its surface. The concept encompasses geochemical differ�  entiation (natural separation and concentration of elements) and heat-  assisted recombination processes. Changes may not be apparent over a  short term, but over a long term changes of great magnitude occur, includ�  ing the evolution of continents and oceans.</p><p>geochemistry Scientific discipline dealing with the relative abun�  dance, distribution, and migration of the Earth�s chemical elements and  their isotopes. Historically, geochemistry was concerned primarily with  defining elemental abundances in minerals and rocks. Modem geochem�  ical research also includes study of the continual recycling of the Earth�s  constituent materials through geologic processes, the cyclic flow of indi�  vidual elements (and their compounds) between living and nonliving sys�  tems, and certain areas of cosmology.</p><p>geochronology Dating and interpretation of geologic events in the  history of the Earth. The classical technique of geochronology was stratig�  raphy, including faunal succession. Since the mid 20th century, radiomet�  ric dating has provided absolute age data to supplement the relative dates  obtained from the fossil record. Radiometric dating is based on the prin�  ciple that radioactive isotopes in geologic material decay at constant,  known rates to daughter isotopes. See also carbon- 14 dating.</p><p>geode Hollow mineral body found in limestones and some shales, com�  monly a slightly flattened globe 1-12 in. (2.5-30 cm) in diameter and  containing a chalcedony layer surrounding an inner lining of crystals. The  hollow interior often is nearly filled with inward-projecting crystals, new  layers growing on top of old. The crystals are often of quartz but some�  times of other minerals.</p><p>geodesy \je-'a-do-se\ Scientific discipline concerned with the size and  shape of the Earth, its gravitational field, and the location of fixed points.

Now satellites  are used in conjunction with the land-based system.</p><p>geoduck Vgu-e-,dak\ Marine  bivalve ( Panopea generosa ) that  inhabits the intertidal zone of the  Pacific coast from southern Alaska to  Baja California. It is the largest  known burrowing bivalve, with a  shell about 7-9 in. (18-23 cm) long  and siphons that extend up to about  4 ft (1.3 m). It may weigh as much  as 8 lbs (3.6 kg). Though highly  prized for food, it lives in deep bur�  rows and is difficult to dig out (the  name probably derives from an  Indian phrase meaning �dig deep�).  Similar species are found in other  parts of the world.</p><p>Geoffrey of Monmouth Vjef-  re...'man-moth \ (d. 1155) Medieval  British chronicler. He was probably  an Oxford cleric for most of his life.  His mostly fictional History of the  Kings of Britain (c. 1135-39) traced  the descent of British princes from  the Trojans; it brought the figure of</p><p>Arthur (see Arthurian legend) into European literature and introduced the  enchanter Merlin, whose story Geoffrey related in the Vita Merlini (c.  1148-51?). Though denounced from the first by other historians, the His�  tory was one of the most popular books of the Middle Ages and had an  enormous influence on later chroniclers.</p><p>geographic information system (GIS) Computerized system that  relates and displays data collected from a geographic entity in the form  of a map. The ability of GIS to overlay existing data with new informa�  tion and display it in colour on a computer screen is used primarily to  conduct analyses and make decisions related to geology, ecology, land  use, demographics, transportation, and other domains, most of which  relate to the human use of the physical environment. Through the process  of geocoding, geographic data from a database is converted into images  in the form of maps.</p><p>geography Science of the Earth�s surface, which describes and ana�  lyzes the spatial variations in physical, biological, and human phenom�  ena that occur on the surface of the globe and treats their interrelationships  and their significant regional patterns. Once associated entirely with map�  ping and the exploration of the Earth, the field today is wide-ranging, and  geographers use a variety of methods and techniques drawn from numer�  ous disciplines. Subfields of geography include physical, human, and  regional geography, which may range in scale from worldwide to a con�  tinent, a country, or a city.</p><p>geologic oceanography See marine geology</p><p>geologic time Interval of time occupied by the Earth�s geologic his�  tory, extending from c. 3.9 billion years ago (corresponding to the age of  the oldest known rocks) to the present day. It is, in effect, the part of the  Earth�s history that is recorded in rock strata. The geologic time scale is  classified in nested intervals distinguished by characteristic geologic and  biologic features. From longest to shortest duration, the intervals are eon,  era, period, and epoch See table on following page.</p><p>geological engineering See engineering geology</p><p>geology Scientific study of the Earth, including its composition, struc�  ture, physical properties, and history. Geology is commonly divided into  subdisciplines concerned with the chemical makeup of the Earth, includ�  ing the study of minerals (mineralogy) and rocks (petrology); the structure  of the Earth (structural geology) and volcanic phenomena (volcanology);  landforms and the processes that produce them (geomorphology and gla�  ciology); geologic history, including the study of fossils (paleontology),  the development of sedimentary strata (stratigraphy), and the evolution of  planetary bodies and their satellites (astrogeology); and economic geology  and its various branches, such as mining geology and petroleum geology.  Some major fields closely allied to geology are geodesy, geophysics, and  GEOCHEMISTRY. See also ENVIRONMENTAL GEOLOGY.</p><p>geomagnetic field Magnetic field associated with the Earth. It is  essentially dipolar (i.e., it has two poles, the northern and southern mag�  netic poles) on the Earth�s surface. Away from the surface, the field  becomes distorted. Most geomagnetists explain the field by means of  dynamo theories, whereby a source of energy in the Earth�s core causes  a self-sustaining magnetic field. In the dynamo theories, fluid motion in  the Earth�s core involves the movement of conducting material within an  existing magnetic field, thus creating a current and a self-enforcing field.</p><p>geomagnetic reversal Alternation of the Earth�s magnetic polarity.  The Earth�s internal magnetic field reverses, on average, about every  300,000 to 1 million years. This reversal is very sudden on a geologic  time scale, apparently taking about 5,000 years. The time between rever�  sals is highly variable, sometimes less than 40,000 years and at other times  as long as 35 million years. No regularities or periodicities have yet been  discovered. A long interval of one polarity may be followed by a short  interval of opposite polarity. See also polar wandering.</p><p>geomagnetics Branch of geophysics concerned with all aspects of the  Earth�s magnetic field, including its origin, variation through time, and  manifestations in the form of magnetic poles, the magnetization of rocks,  and local or regional magnetic anomalies.</p><p>Geometric style Style of vase painting that flourished in Athens c.  1000-700 bc.

Many systems of classifying landforms have  been devised. Some systems describe and group topographic features pri�  marily according to the processes that shaped or modified them. Others  take additional factors into consideration (e.g., character of the surface  rocks and climatic variations) and include the developmental stage of  landforms as an aspect of their evolution over geologic time.</p><p>geophysics Major branch of earth science that applies the principles  and methods of physics to the study of the Earth. Geophysics deals with  such geologic phenomena as the temperature distribution of the Earth�s  interior; the source, configuration, and variations of the geomagnetic field;  and the large-scale features of the terrestrial crust, such as rifts, conti�  nental sutures, and oceanic ridges. Modem geophysical research also  examines phenomena of the outer parts of the Earth�s atmosphere and  even the physical properties of other planets and their satellites. See also  MARINE GEOPHYSICS.</p><p>geopolitics The study of geographic influences on power relationships  in international politics. Geopolitical theorists have sought to demonstrate  the importance in the determination of foreign policies of considerations  such as the acquisition of natural boundaries, access to important sea  routes, and the control of strategically important land areas. The term was  first employed in the early 20th century by the Swedish political scientist  Rudolph Kjellen (1864-1922). Geopolitical factors have become less sig�  nificant in the foreign policies of states because of improvements in com�  munications and transportation.</p><p>George I orig. George Louis German Georg Ludwig (b. May</p><p>28, 1660, Osnabriick, Hanover�d. June 11, 1727, Osnabruck) First king  of England (1714-27) from the house of Hanover. He succeeded his father  as the elector of Hanover (1698) and fought with distinction in the War  of the Spanish Succession. As a great-grandson of James I of England and  under the Act of Settlement, George ascended the English throne in 1714.  He formed a Whig ministry and left internal politics to his ministers,  including 1 st Earl Stanhope, Viscount Townshend, and Robert Walpole. He  was unpopular because of his German manner and German mistresses and</p><p>their involvement in the South Sea Bubble crisis, but he strengthened Brit�  ain�s position by forming the Quadruple Alliance (1718). He was suc�  ceeded by his son, George II.</p><p>George I Greek Georgios orig. Prince William of Denmark</p><p>(b. Dec. 24, 1845, Copenhagen, Den.�d. March 18, 1913, Salonika,  Greece) King of Greece. Son of Christian IX of Denmark, he served in the  Danish navy and in 1862 was nominated to the Greek throne by Britain,  France, and Russia after the Greek king, Otto, was deposed. Accepted by  the Greek National Assembly, he ascended the throne as George 1 in 1863.  He oversaw the incorporation of territory in Thessaly and Epirus into  Greece as well as the annexation of Crete. In the unrest caused by the  Balkan Wars, he was assassinated at Salonika; he was succeeded by his  son, Constantine I. His long reign was the formative period for the devel�  opment of Greece as a modem European state.</p><p>George II orig. George Augustus German Georg August (b.</p><p>Nov. 10, 1683, Herrenhausen Palace, Hanover�d. Oct. 25, 1760, Lon�  don, Eng.) King of Great Britain and elector of Hanover (1727-60). His  father, the elector of Hanover, became George I of England; he succeeded  him in both roles in 1727. He retained Robert Walpole as his key minister  until 1742. His new minister, John Carteret (1690-1763), brought England  into the War of the Austrian Succession, where George fought coura�  geously at the Battle of Dettingen (1743), the last time a British king  appeared on the battlefield. The parliament and ministers forced Carter�  et�s resignation and the appointment of William Pitt. George lost interest  in politics, and Pitt�s strategy brought about a British victory in the Seven  Years' War.</p><p>George II Greek Georgios (b. July 20, 1890, Tatoi, near Athens,  Greece�d. April 1, 1947, Athens) King of Greece (1922-24, 1935-47).  He became king when his father, Constantine I, was deposed in 1922, but  the royal family was unpopular and George fled Greece in 1923. The  National Assembly proclaimed Greece a republic in 1924. George  remained in exile until the conservative Populist Party, with army sup�  port, gained control of the legislature and restored the monarchy in 1935.  Ioannis Metaxas seized power in 1936 with the king�s support. George  was forced into exile in 1941 in World War II; republican sentiment threat�  ened his throne, but he was restored by a plebiscite and returned to Greece  in 1946.</p><p>George III orig. George William Frederick (b. June 4, 1738,  London, Eng.�d. Jan. 29, 1820, Windsor Castle, near London) King of  Great Britain and Ireland (1760-1820); also elector (1760-1814) and king  (1814-20) of Hanover. The grandson of George II, he ascended the throne  during the Seven Years' War. His chief minister, Lord Bute, forced Wil-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>George IV &#x25BA; Georgetown University I 751</p><p>liam Pitt�s resignation and caused intrigue rather than stability within the  government. Bute resigned in 1763, but George�s political overtures to  others were snubbed, until Lord North became prime minister in 1770.  England was in financial distress caused by the war, and George supported  attempts to raise funds through taxation of the American colonies, which  led to the American Revolution. With North, he was blamed for prolong�  ing the war and losing the colonies. He reasserted his power when North  and Charles James Fox planned to take control of the East India Company;  he forced them to resign and reaffirmed his control through a new �patri�  otic� prime minister, William Pitt, the Younger. George supported him until  the war with Revolutionary France (1793) and fears of related uprisings  in Ireland caused Pitt to propose political emancipation of the Roman  Catholics. George�s vehement opposition led to Pitt�s resignation in 1801.  In 1811 George�s ill health and a return of the madness that had afflicted  him for short periods earlier in his life caused Parliament to enact the  regency of his son, the future George IV.</p><p>George IV orig. George Augustus Frederick (b. Aug. 12, 1762,  London, Eng.�d. June 26, 1830, Windsor, Berkshire) King of the United  Kingdom (1820-30) and king of Hanover (1820-30). The son of George  III, he earned his father�s ill will by his extravagances and dissolute hab�  its, contracting a secret marriage that was annulled by his father. In 1811  George became regent for his father, who had been declared insane.  Retaining his father�s ministers rather than appointing his Whig friends,  he saw Britain and its allies triumph over Napoleon in 1815. A patron of  the architect John Nash, he sponsored the restoration of Windsor Castle.</p><p>George V orig. George Frederick Ernest Albert (b. June 3,  1865, London, Eng.�d. Jan. 20,</p><p>1936, Sandringham, Norfolk) King  of the United Kingdom (1910-36).</p><p>The second son of the future Edward  VII, he succeeded his father in 1910.</p><p>Early in his reign, he faced problems  resulting from the constitutional  struggle to restrict the power of the  House of Lords. Respect for the new  king increased during World War I,  and he visited the front in France  several times. After the war he faced  both serious industrial unrest and, in  1923, the resignation as prime min�  ister of Andrew Bonar Law, who was  replaced by Stanley Baldwin. After  the collapse of the pound sterling and  the subsequent financial crisis in  1931, he persuaded James Ramsay  MacDonald to remain in office and  form a national coalition government. He was succeeded successively by  his sons Edward VIII and George VI.</p><p>George VI orig. Albert Frederick Arthur George (b. Dec. 14,  1895, Sandringham, Norfolk,</p><p>Eng.�d. Feb. 6, 1952, Sandring�  ham) King of the United Kingdom  (1936-52). The second son of  George V, he was proclaimed king  following the abdication of his  brother, Edward VIII. He was an  important symbolic leader of the  British people during World War II,  supporting the wartime leadership of  Winston Churchill and visiting his  armies on several battlefronts. In  1949 he was formally recognized as  head of the Commonwealth by its  member states. He earned the respect  of his people by scrupulously  observing the responsibilities of a  constitutional monarch and by over�  coming the handicap of a severe stammer. He was succeeded by his  daughter, Elizabeth II.</p><p>George, David Lloyd See David Lloyd George</p><p>George, Henry (b. Sept. 2, 1839, Philadelphia, Pa., U.S.�d. Oct. 29,  1897, New York, N.Y.) U.S. land reformer and economist. He left school  before age 14 to work as a clerk and then at sea. In 1858 George went to  California, where he worked for newspapers (briefly founding his own)  and took part in Democratic party politics. In 1879 he published Progress  and Poverty, in which he proposed that the state fully tax all economic  rent�the income from the use of the bare land, but not from  improvements�and abolish all other taxes. George believed that the gov�  ernment�s annual income from this �single tax� would be so large that  there would be a surplus for expansion of public works.</p><p>George, Lake Lake, northeastern New York, U.S. It is 32 mi (51 km)  long and 1-4 mi (1.6-6.4 km) wide and is connected to Lake Champlain  through a series of waterfalls. In the foothills of the Adirondacks, it is noted  for its scenic beauty and is a popular resort area. Memorialized in James  Fenimore Cooper�s novels as Lake Horicon, the real lake was the scene of  numerous battles during the French and Indian War and the American Revo�  lution. Fort Ticonderoga is located on the falls at the lake�s outlet.</p><p>George, Saint (fl. 3rd century�d. traditionally Lydda, Palestine; feast  day April 23) Early Christian martyr and patron saint of England. His his�  torical existence is uncertain, but from the 6th century he was the subject  of legends as a warrior-saint. He was said to have rescued a Libyan king�s  daughter from a dragon, which he killed in return for a promise that the  king�s subjects would be baptized. In art, the young saint often wears  knight�s armor ornamented with a scarlet cross. He probably became  England�s patron saint in the 14th century, when Edward III made him  patron of the Order of the Garter.</p><p>George \ga-'6r-go\, Stefan (b. July 12, 1868, Budesheim, near Bin�  gen, Hesse�d. Dec. 4, 1933, Minusio, near Locarno, Switz.) German  poet. George traveled widely, becoming associated with Stephane Mallarme  and the Symbolist movement in Paris and the Pre-Raphaelites in London.  Returning to Germany, he edited the journal Blatter fur die Kunst (1892�  1919) and became the centre of the �George Circle,� gathering young  poets around him in a close-knit aesthetic band. His collections include  Hymnen (1890), Das Jahr der Seele (1897), Der siebente Ring (1907),  and Der Stern des Bundes (1914). A supporter of �pure poetry,� he  opposed not only the debasement of the language but also materialism  and naturalism. Though politically conservative, he turned down Nazi  offers of money and honours, preferring exile. His collected works include  translations of Dante and William Shakespeare (the sonnets) as well as prose  sketches.</p><p>George Washington Birthplace National Monument</p><p>National monument, eastern Virginia, U.S. Established in 1930, it con�  sists of 538 acres (218 hectares) located along the Potomac River.

Language: Georgian (official).  Religions: Christianity (Eastern Orthodox, Armenian Apostolic); also  Islam. Currency: lari. Most of Georgia is mountainous, and many peaks  rise above 15,000 ft (4,600 m). The Caucasus protect it against cold air  from the north, and the climate is mainly subtropical. Fertile lowlands lie  near the shores of the Black Sea. Georgia has a well-developed industrial  base noted for its hydroelectric power, coal mining and steel making,  machinery production, and textiles. Agricultural land is in short supply, and  farming is difficult; crops include tea, citrus fruits, grapes (for wine), sugar  beets, and tobacco. Georgia is a republic with one legislative body; the head  of state and government is the president, assisted by the prime minister.  Ancient Georgia was the site of the kingdoms of Iberia and Colchis, whose  fabled wealth was known to the ancient Greeks. The area was part of the  Roman Republic by 65 bc and became Christian in ad 337. For the next  three centuries, it was involved in the conflicts between the Byzantine and  Persian empires; after 654 it was controlled by Arab caliphs, who estab�  lished an emirate in Tbilisi. It was ruled by the Armenian Bagratids from  the 8th to the 12th century, and the zenith of Georgia�s power was reached  in the reign of Queen Tamara, whose realm stretched from Azerbaijan to  Circassia, forming a pan-Caucasian empire. Invasions by Mongols and  Turks in the 13th-14th century disintegrated the kingdom, and the fall of  Constantinople to the Ottoman Empire in 1453 isolated it from Western  Christendom. There were repeated invasions over the next three centuries  by the Armenians, Ottomans, and Persians. Georgia sought Russian pro�  tection in 1783 and in 1801 was annexed by the Russian Empire. After the  Russian Revolution of 1917, the area was briefly independent; in 1921 a  Soviet regime was installed, and in 1936 Georgia became the Georgian  S.S.R., a full member of the Soviet Union. In 1990 a noncommunist coa�  lition came to power in the first free elections ever held in Soviet Georgia,  and in 1991 Georgia declared independence. In the 1990s, while President  Eduard Shevardnadze tried to steer a middle course, internal dissension  sparked conflicts in Abkhazia.</p><p>Georgia State (pop., 2000: 8,186,453), southeastern U.S. It is bordered  by Tennessee, North Carolina, South Carolina, Florida, and Alabama; the  Atlantic Ocean lies to the southeast. The last of the original 13 English  colonies, Georgia covers 58,930 sq mi (152,629 sq km) and is the largest  state east of the Mississippi River; its capital is Atlanta. The area was</p><p>inhabited by the Creek and Cherokee Indians when Spanish missionaries  arrived in the 16th century. English settlement began in 1733 at Savan�  nah when James Oglethorpe established a refuge for debtors. European  settlement accelerated after the American Revolution, and the last of the  Indians were forcibly removed in the 1830s. Georgia seceded from the  Union in 1861, and the American Civil War was particularly hard on the  state. It was the last former Confederate state to be readmitted to the Union  in 1870. Its landscape sweeps from the Blue Ridge in the north to the  Okefenokee Swamp (which it shares with Florida) in the south. For most  of the 19th century it was the capital of the cotton empire of the South;  in the 20th century industry predominated. The state�s population grew  throughout the 20th century, with Atlanta especially attracting national  corporations.</p><p>Georgia, Strait of Channel in the Pacific Ocean, southwestern Canada  and northwestern U.S. Located between Vancouver Island, the southwest�  ern mainland of British Columbia, and northwestern Washington state, it  is 150 mi (241 km) long and 30 mi (28 km) at its widest. To the north  the strait ends in a jumble of islands separating it from Johnstone and  Queen Charlotte straits. The southern end is marked by the San Juan  Islands of Washington and joins Haro Strait, forming a link in the Inside  Passage sea route between Seattle, Wash., and Skagway, Alaska.</p><p>Georgia Institute of Technology known as Georgia Tech Pub�  lic institution of higher learning in Atlanta, Georgia, U.S., founded in  1885. It consists of colleges of architecture, computing, engineering, sci�  ences, and public policy and administration. Undergraduate and graduate  degrees are offered. Georgia Tech is home to a nuclear research centre  and several other research and development centres.</p><p>Georgian Bay Inlet, Lake Huron, southeastern Ontario, Canada. Shel�  tered from the rest of the lake by Manitoulin Island and the Bruce Pen�  insula, it is 120 mi (190 km) long and 50 mi (80 km) wide; its maximum  depth is 540 ft (165 m). The Georgian Bay Islands National Park, estab�  lished in 1929, comprises some 40 islands in the southeastern and west�  ern parts of the bay. The Thirty Thousand Islands along the bay�s eastern  shore constitute a popular summer resort area.</p><p>Georgian language Caucasian language of the Republic of Georgia,  spoken by about 4.1 million people worldwide. Georgian is unique among  Caucasian languages in having an ancient literary tradition. The earliest  attestation of the language is an inscription of ad 430 in a church in Pal�  estine, in a script ancestral to that used for Old Georgian (5th�11th cen�  turies). The civil script used to write Modern Georgian, with 33 characters  and no distinction between upper- and lowercase, was an offshoot of a  script that first appeared in the 10th century. The origins of Georgian  writing are uncertain, though it was presumably a free adaptation of the  Greek alphabet, with new characters invented for the sounds peculiar to  Georgian. Georgian has features typical of other Caucasian languages,  including a large consonant inventory (with clusters of up to six conso�  nants appearing at the beginning of a word).</p><p>Georgian poetry Body of lyrical poetry produced in Britain in the  early 20th century. Desiring to make new poetry more accessible to the  public, Rupert Brooke and Sir Edward Marsh produced five anthology  volumes�containing works by Robert Graves, Walter de la Mare, Sieg�  fried Sassoon (1886-1967), and others�called Georgian Poetry (1912�  22). �Georgian� was meant to suggest the opening of a new poetic age  with the accession in 1910 of George V; however, much of the Georgians�  work was conventional, and the name came to refer to backward-looking  literature rooted in its time.</p><p>Georgian style Architecture, interior design, and decorative arts of  Britain during the reigns (1714-1830) of the first four Georges. It encom�  passed Palladianism (see Andrea Palladio), turned to an austere Neoclas�  sicism, moved on to Gothic Revival, and ended with the Regency style. The  era is said to mark the summit of house design in Britain. Its legacy can  be seen in the city squares of uniform, symmetrical brick London town-  houses, their facades employing Classical pilasters, pedimented doors and  windows, and graceful moldings. Their interiors, often furnished with  Chippendale and Sheraton pieces, were characterized by harmonious pro�  portions, quiet colors, and Roman-derived stucco ornamentation.</p><p>geosync line Linear trough of subsidence of the Earth�s crust, in which  vast amounts of sediment accumulate.

Most geothermal resources are in regions of active volcanism. Hot  springs, geysers, pools of boiling mud, and fumaroles are the most easily  exploited sources. The ancient Romans used hot springs to heat baths and  homes, and similar uses are still found in Iceland, Turkey, and Japan.  Geothermal energy�s greatest potential lies in the generation of electric�  ity. It was first used to produce electric power in Italy in 1904. Today  geothermal power plants are in operation in New Zealand, Japan, Iceland,  Mexico, the U.S., and elsewhere.</p><p>Gerald of Wales See Giraldus Cambrensis</p><p>geranium Any of the approximately 300 species of perennial herba�  ceous plants or shrubs that make up  the genus Geranium (family Gerani-  aceae), native mostly to subtropical  southern Africa. They are among the  most popular bedding and green�  house plants. The closely related  genus Pelargonium contains some  280 species of annual, biennial, and  perennial herbaceous plants also  commonly called geraniums. The  showy, or Martha Washington, gera�  niums ( P . x domesticum ) have large  pansylike flowers, few to the cluster.</p><p>Some geraniums are grown as bas�  ket plants indoors and out; they are  also used as ground covers in warm  areas. Some species have fragrant  leaves. Geranium oil smells like  roses and is used chiefly in perfumes,  soaps, and ointments.</p><p>gerbil Vjar-bslX Any of almost 100 species (subfamily Gerbillinae) of  burrowing mouselike rodents found in Africa and Asia, usually in dry,  sandy areas but also in grasslands, cultivated fields, or forests. Gerbils  have large eyes and ears and soft, brown or grayish fur. Most are 4-6 in.  (10-15 cm) long, excluding the long, hairy tail. Many species have long  hind legs used for leaping. Gerbils feed primarily on seeds, roots, and  other plant material. One species ( Meriones unguiculatus ) is a popular  pet. The great gerbil ( Rhombomys opimus ) sometimes damages crops and  embankments in Russia, and members of one African genus ( Tatera ) are  possible carriers of bubonic plague.</p><p>geriatrics See gerontology and geriatrics</p><p>Gericault V.zha-ri-'koV (Jean-Louis-Andre-) Theodore (b. Sept.  26, 1791, Rouen, Fr.�d. Jan. 26,1824, Paris) French painter. Under Pierre  Guerin (1774-1833) he developed great skill in figure construction and  composition, and under Joseph Vernet he became adept at capturing animal  movement. He was inspired by Peter Paul Rubens�s use of colour and the  contemporary subject matter of Antoine-Jean Gros. On a trip to Italy  (1816�17), he became an admirer of Michelangelo and art of the Baroque  period. On his return to Paris, the macabre subject matter and political over�  tones of his huge Raft of the Medusa (1818-19) aroused great controversy.  In 1820-21 he went to England and produced a large body of lithographs,  watercolours, and oils of jockeys and horses. An avid horseman, he died  after a riding accident. His work had enormous influence, most notably on  Eugene Delacroix, and on the development of Romanticism in France.</p><p>germ-plasm theory Concept of the physical basis of heredity  expressed by the biologist August Weismann (1834-1914). It claimed that  germ plasm, which Weismann believed to be independent from all other  cells of the body, was the essential element of germ cells (eggs and sperm)  and was the hereditary material passed from generation to generation.  First proposed in 1883, his view contradicted Lamarck�s then-prevalent  theory of acquired characteristics. Though its details have been altered,  its idea of the stability of hereditary material is the basis of the modem  understanding of physical inheritance.</p><p>germ theory Theory that certain diseases are caused by invasion of  the body by microorganisms. Louis Pasteur, Joseph Lister, and Robert Koch</p><p>are given much of the credit for its acceptance in the later 19th century.  Pasteur showed that organisms in the air cause fermentation and spoil food;  Lister was first to use an antiseptic to exclude germs in the air to prevent  infection; and Koch first linked a specific organism with a disease  (anthrax). The full implications of germ theory for medical practice were  not immediately apparent after it was proven; surgeons operated without  masks or head coverings as late as the 1890s.</p><p>germ warfare See biological warfare</p><p>Germain \zher-'ma n \, Thomas (b. 1673, Paris, Fr.�d. Aug. 14, 1748,  Paris) French silver- and goldsmith. He studied painting as a boy and in  1691 was apprenticed to a silversmith in Rome. From 1706 to the 1720s,  back in France, he worked on church commissions, such as a silver-gilt  monstrance for Notre-Dame de Paris (1716). He became a master in the  guild in 1720, and in 1723 Louis XV appointed him a royal goldsmith.  Among his patrons were the queen of Spain, the king and queen of Naples,  and the Portuguese court; his workshop produced some 3,000 silver  objects for the palace at Lisbon over a 40-year period. He is best known  for elaborate objects in Rococo style, though some of his pieces display a  more restrained elegance.</p><p>German Civil Code German Burgerliches Gesetzbuch Body of  codified private law that went into effect in the German Empire in 1900.  The code, since modified, developed out of a desire for a truly national  law that would override the often conflicting customs and law codes of  the various German territories. Divided into five parts, it covers personal  rights and legal personality, the law of contracts and sales, property,  domestic relations, and inheritance, or succession. It contains elements of  Germanic tribal, feudal, and common law, as well as Roman law. It has  significantly influenced the private law of other countries, particularly  Japan, Switzerland, and Greece. See also Germanic law.</p><p>German Confederation (1815-66) Organization of the states of  central Europe, established by the Congress of Vienna to replace the  destroyed Holy Roman Empire. It was a loose political association of 39  German states, formed for mutual defense, with no central executive or  judiciary. Delegates met in a federal diet dominated by Austria. Amid a  growing call for reform and economic integration, conservative leaders,  including Klemens, prince von Metternich, persuaded the confederation�s  princes to pass the repressive Carlsbad Decrees (1819), and in the 1830s  Metternich led the federal diet in passing additional measures to crush  liberalism and nationalism. The formation of the Zollverein and the Revo�  lutions of 1 848 undermined the confederation. It was dissolved with the  Austro-Prussian War (1866) and the establishment of the North German  Confederation.</p><p>German East Africa Former dependency of imperial Germany, cor�  responding to present-day Rwanda and Burundi, the continental portion  of Tanzania, and a small section of Mozambique. German commercial  agents arrived in 1884, and in 1891 the German imperial government took  over administration of the area. During World War I, it was occupied by  the British, who received a mandate to administer the greater part of it  (Tanganyika Territory) by the Treaty of Versailles (1919). A smaller por�  tion (Ruanda-Urundi) was entrusted to Belgium.</p><p>German historical school of economics Branch of economic  thought, developed chiefly in Germany in the later 19th century, in which  the economic situation of a nation is understood as the result of its total  historical experience. Objecting to the deductively reasoned �laws� of  classical economics, exponents of the historical approach examined the  development of the entire social order, of which economic motives and  decisions were only one component. They viewed government interven�  tion in the economy as a positive and necessary force. Early founders,  including Wilhelm Roscher and Bruno Hildebrand, developed the idea of  the historical method and sought to identify general stages of economic  development through which all countries must pass. Members of the later  school, notably Gustav von Schmoller (1813-1917), carried out more  detailed historical research and attempted to discover cultural trends  through historical inquiry.</p><p>German language Official language of Germany and Austria and one  of the official languages of Switzerland, used by more than 100 million  speakers.

Hostile to the republic, it supported the restoration of the monarchy and  a united Germany. During a controversy (1929-30) over paying war repa�  rations to the Allies, the party, led by Alfred Hugenberg, allied with the  Nazi Party in favor of stopping payments. In 1933 it joined a coalition that  supported Adolf Hitler as chancellor and passed the Enabling Act; along  with all German political parties except the Nazis, the party was dissolved  three months later.</p><p>German People's Party (DVP) Right-liberal political party  founded by Gustav Stresemann in 1918, made up largely of the educated  and propertied. Since Stresemann was essentially a monarchist, when he  decided to cooperate with the Weimar Republic the DVP was at first  excluded as being among the �national opposition.� When Stresemann  became chancellor in 1923, the DVP was part of the �Great Coalition,�  composed of representatives of the Social Democrats, the Center, and the  German Democrats. It dwindled c. 1927, and large sections of it went  over to the extreme right.</p><p>German shepherd or Alsatian Breed of working dog developed in  Germany from traditional herding  and farm dogs.

The Soviet Union,  whose proposed collective security agreement with Britain and France  was rebuffed, approached Germany, and in the pact the two states pledged  publicly not to attack each other. Its secret provisions divided Poland  between them and gave the Soviet Union control of Latvia, Lithuania,  Estonia, and Finland. The Soviets hoped to buy time to build up their  forces to face German expansionism; Germany wished to proceed with  its invasion of Poland and the countries to its west without having to worry  about the Red Army. News of the pact shocked and horrified the world.  Nine days after its signing, Germany began World War II by invading  Poland. The agreement was voided when Germany attacked the Soviet  Union in 1941. Until 1989 the Soviet Union denied the existence of the  secret protocols because they were considered evidence of its involuntary  annexation of the Baltic states.</p><p>Germanic \jor-'ma-nik\ languages Branch of the Indo-European lan�  guage family, comprising languages descended from Proto-Germanic.  These are divided into West Germanic, including English, German, Frisian,  Dutch, Afrikaans, and Yiddish; North Germanic, including Danish, Swed�  ish, Icelandic, Norwegian, and Faeroese (the language of the Faroe  Islands); and East Germanic, now extinct, comprising Gothic and the lan�  guages of the Vandals, Burgundians, and a few other tribes. The Gothic  Bible of ad 350 is the earliest extensive Germanic text. The West Ger�  manic languages developed around the North Sea and in overseas areas  colonized by their speakers. The North Germanic, or Scandinavian, lan�  guages, were carried as far west as Greenland and as far east as Russia  in the Viking expansion of the early Middle Ages. The continental Scan�  dinavian languages were strongly influenced by Low German in the late  Middle Ages, but Icelandic and Faeroese have preserved many charac�  teristics of Old Scandinavian grammar.</p><p>Germanic law Law of the various Germanic peoples from ancient  times to the Middle Ages. It was essentially unwritten tribal custom, which</p><p>evolved from popular practice and moved with the tribe. With the spread  of Christianity, ecclesiastical law, derived from Roman law, gained impor�  tance, especially in matters of marriage and succession. A mercantile law,  developed by the 12th century to meet the needs of traders, further eroded  the power of local law.</p><p>Germanic religion Beliefs, rituals, and mythology of the pre-  Christian Germanic peoples, in a geographic area extending from the  Black Sea across central Europe and Scandinavia to Iceland and Green�  land. The religion died out in central Europe with the conversion to Chris�  tianity (4th century) but continued in Scandinavia until the 10th century.  The Old Norse literature of medieval Iceland, notably the Poetic Edda (c.  1200) and the Prose Edda (c. 1222), recounts the lore of the Germanic  gods. The earth was held to have been created out of a cosmic void called  Ginnungagap; in another account the first gods formed it from the body  of a primeval giant, Aurgelmir. There were two sets of gods in the Ger�  manic pantheon, the warlike Aesir and the agricultural Vanir. Germanic  religion also encompassed belief in female guardian spirits, elves, and  dwarfs. Rites were conducted in the open or in groves and forests; ani�  mal and human sacrifice was practiced. Ragnarok is the Germanic dooms�  day.</p><p>Germanicus Vjor-'ma-ni-kosN Caesar (b. 15 bc �d. ad 19, Antioch,  Syria) Nephew and adopted son of Tiberius, brother of Claudius, and father  of Caligula and Agrippina the Younger. A successful and popular general,  he stifled a rebellion in the West on the death of Augustus in ad 14. Though  urged to take imperial power, he deferred to Tiberius, under whom he had  served. In the East he came into conflict with Gnaeus Calpurnius Piso,  governor of Syria. Germanicus�s death may have been due to poisoning  ordered by Piso, though Tiberius was also suspected; Piso�s suicide left  the matter unsolved. Only his premature death prevented Germanicus  from becoming emperor.</p><p>germanium Semimetallic chemical element, chemical symbol Ge,  atomic number 32. Germanium, which resembles silicon in its physical  properties, is used especially in semiconductor devices. Discovered in  1886, it became economically significant after 1945 and remains of pri�  mary importance in the manufacture of transistors and of components for  other devices such as rectifiers (see diode) and photocells. It is also used  as a component of alloys, in phosphors for fluorescent lamps, and in the  glasses of certain optical components, such as camera and microscope  lenses.</p><p>Germantown, Battle of (Oct. 4, 1777) Abortive attack in the Ameri�  can Revolution by 11,000 American troops on 9,000 British regulars sta�  tioned at Germantown (now part of Philadelphia). George Washington�s  daring dawn raid, a four-pronged attack, failed partly because of dense  fog that confused the American troops into firing on one of their own col�  umns. Despite its failure, this and the colonial victory at the Battle of  Saratoga impressed the French with Washington�s strategic ability and  influenced them to offer military aid.</p><p>Germany officially Federal Republic of Germany Country,  north-central Europe. Area: 137,847 sq mi (357,023 sq km). Population  (2005 est.): 82,467,000. Capital: Berlin. The majority of the people are  German. Language: German (official). Religions: Christianity (Protestant,  Roman Catholic, other Christians); also Islam. Currency: euro. The land  is generally flat in the north and hilly in the northeast and central region,  rising to the Bavarian Alps in the south. The Rhine River basin dominates  the central and western part of the country; other important rivers include  the Elbe, Danube, and Oder. Germany has a developed free-market  economy largely based on services and manufacturing. It is one of the  richest countries in the world. Exports include motor vehicles and iron  and steel products. The chief of state is the president, and the head of  government is the chancellor. Federal power is centred in the bicameral  Parliament. Germanic tribes entered Germany c. 2nd century bc, displac�  ing the Celts. The Romans failed to conquer the region, which became a  political entity only with the division of the Carolingian empire in the 9th  century ad. The monarchy�s control was weak, and power increasingly  devolved upon the nobility, organized in feudal states. The monarchy was  restored under Saxon rule in the 10th century, and the Holy Roman Empire,  centring on Germany and northern Italy, was revived. Continuing conflict  between the Holy Roman emperors and the Roman Catholic popes under�  mined the empire, and its dissolution was accelerated by Martin Luther�s  revolt (1517), which divided Germany, and ultimately Europe, into Prot�  estant and Catholic camps, culminating in the Thirty Years' War (1618�</p><p>German shepherd</p><p>SALLY ANNE THOMPSON/EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Germany &#x25BA; gerousia I 755</p><p>48). Germany�s population and borders  were greatly reduced, and its numerous feu�  dal princes gained virtually full sovereignty.</p><p>In 1862 Otto von Bismarck came to power  in Prussia and in 1871 united the Germans,  founding the German Empire. It was dissolved in 1918 after its defeat in  World War I, and the Weimar Republic was declared. Germany was stripped  of much of its territory and all of its colonies. In 1933 Adolf Hitler became  chancellor and established a totalitarian state, the Third Reich, dominated  by the Nazi Party. Hitler invaded Poland in 1939, plunging the world into  World War II, and he was responsible for the Holocaust, the systematic  killing of some six million Jews and millions of others. Following its  defeat in 1945, Germany was divided by the Allies into four zones of  occupation. Disagreement with the Soviet Union over their reunification  led to the creation in 1949 of the Federal Republic of Germany (West  Germany) and the German Democratic Republic (East Germany). Berlin,  the former capital, remained divided. West Germany became a prosper�  ous parliamentary democracy, East Germany a one-party state under  Soviet control. In 1952 Germany became a founding member of the Euro�  pean Coal and Steel Community, the forerunner of the European Union. The  East German communist government was overthrown peacefully in 1989,  and Germany was reunited in 1990. After the initial euphoria over unity,  the political and economic integration of the former East Germany into  the federal republic resulted in heavy financial burdens for the wealthier  former West Germans. However, the country continued to move toward  deeper political and economic integration with western Europe through  its membership in the European Union.</p><p>Germany, East officially German Democratic Republic Former  republic (1945-90), north-central Europe. It is now the eastern portion of  the Federal Republic of Germany. In 1945 occupied Germany was divided  into U.S., British, French, and Soviet zones. In 1949 the U.S., British, and  French zones were combined as West Germany, while the Soviet zone  became a communist state as East Germany. Declared a sovereign coun�  try in 1955, it became a founding member of the Warsaw Pact. The  regimes of Walter Ulbricht and later Erich Honecker were harshly repres�  sive. The Berlin Wall was constructed at the border of the divided city of  Berlin in 1961 to stem the flight of East German citizens to the West. The  communist government was dismantled in 1989-90, and the country  adopted the constitution and name of Germany when the states were  united in October 1990.</p><p>Germany, West officially Federal Republic of Germany</p><p>Former republic (1949-90), west-central Europe.

Some  of Gerry�s new districts were necessarily odd-shaped; one district�s out�  line, seen to resemble a salamander, gave rise to the scornful term ger�  rymander. The practice has persisted, and redistricting battles in state  legislatures have often had to be decided by the courts. In some countries,  independent commissions have been appointed to draw district bound�  aries.

Born to Russian-Jewish immi�  grants, he heard JAZZ performed live  from about age six. In his teens he  worked as a song plugger (playing  piano in Tin Pan Alley to demonstrate  sheet music for potential customers),  and in 1916 he published his first  song. In 1919 his �Swanee� was per�  formed by Al Jolson and achieved  extraordinary success. Gershwin�s  first complete score was for the show  La, La Lucille (1919). The band�  leader Paul Whiteman commissioned  from him the hugely successful  orchestral work Rhapsody in Blue  (1924). It was revolutionary for its  incorporation of the jazz idiom (blue  notes, syncopated rhythms, onomatopoeic instrumental effects) into a  symphonic context. Gershwin�s first major Broadway success. Lady, Be  Good! (1924), was a collaboration with his brother, lyricist Ira Gershwin.  They soon established themselves as one of the great teams in Broadway  history; their shows included Oh, Kay! (1926), Strike Up the Band (1927),  Funny Face (1927), Girl Crazy (1930), and the satire Of Thee 1 Sing  (1931), the first musical to win a Pulitzer Prize. He also scored several  successful films. His most ambitious work was the �folk opera� Porgy  and Bess (1935), a collaboration with Ira and novelist DuBose Heyward.  Gershwin�s classical compositions include a piano concerto (1925) and  the tone poem An American in Paris (1928). His early death was the result  of a brain tumour.</p><p>Gershwin, Ira orig. Israel Gershvin (b. Dec. 6, 1896, New York,  N.Y., U.S.�d. Aug. 17,1983, Beverly Hills, Calif.) U.S. lyricist, brother of  the composer George Gershwin. He briefly attended City College of New  York, then did odd jobs until his brother asked him to write lyrics for his  melodies; their first collaboration was �The Real American Folk Song,� in  the musical Ladies First (1918). The renowned Gershwin partnership  resulted in such idiomatic and ingenious songs as ��S Wonderful,� �I Got  Rhythm,� �Embraceable You,� �Summertime,� and �It Ain�t Necessarily  So.� After his brother�s death Ira collaborated on a number of musicals,  including Lady in the Dark with Kurt Weill (1940), Cover Girl with Jerome  Kern (1944), and A Star Is Born with Harold Arlen (1954).</p><p>Gesell \g3-'zel\, Gerhard A(lden) (b. June 16, 1910, Los Angeles,  Calif., U.S.�d. Feb. 19, 1993, Washington, D.C.) U.S. judge. He earned  a law degree from Yale University, and he served as an attorney for the  Securities and Exchange Commission (1935�40) and in private practice</p><p>in Washington, D.C. (1941-67). In 1967 Pres. Lyndon B. Johnson  appointed him to the Federal District Court in Washington, D.C. There he  struck down a local ban on abortion (1969) and allowed the resumption  of publication of the Pentagon Papers (1971). He ruled in 1974 that  national security was not a valid reason for the 1971 Watergate break-in  and made other significant rulings regarding the scandal. In charges stem�  ming from the Iran-Contra Affair, he presided over the criminal trial of  National Security Council staff member Lt. Col. Oliver North in 1989. He  remained on the bench until his death.</p><p>gesneriad \ges-'nir-e-,ad\ Any of more than 1,800 species of mostly  tropical and subtropical herbaceous or slightly woody plants in the fam�  ily Gesneriaceae.

Very popular in its time, it became a source  for much later literature, including works by Geoffrey Chaucer and Wil�  liam Shakespeare. It contains stories from Classical history and legend and  from various Asian and European sources, many about magicians and  monsters, ladies in distress, and escapes from perilous situations, all uni�  fied by their moral purpose and realistic detail. Its author is unknown. Its  didactic nature and the allegorical explanations attached to the stories in  the early versions suggest that it was intended as a manual for preachers.  It is likely that it was compiled in England.</p><p>Gestalt Xgo-'stalt, ge-'shtalt\ psychology Twentieth-century school of  psychology that provided the foundation for the modem study of perception.  The German term Gestalt, referring to how a thing has been �put together�  ( gestellt ), is often translated as �pattern� or �configuration� in psychology.  Its precepts, formulated as a reaction against the atomistic orientation of  previous theories, emphasized that the whole of anything is different from  the sum of its parts: organisms tend to perceive entire patterns or configu�  rations rather than bits and pieces. The school emerged in Austria and Ger�  many at the end of the 19th century and gained impetus through the works  of Max Wertheimer, Wolfgang Kohler, and Kurt Koffka (1886-1941); its  principles were later expanded by Kurt Lewin. A form of psychotherapy only  loosely related to Gestalt principles and influenced by existentialism and phe�  nomenology was developed by Frederick S. (Fritz) Peris (1893-1970) in  the 1940s. Gestalt therapy directs the client toward appreciating the form,  meaning, and value of his perceptions and actions.</p><p>Gestapo \go-'sta-po\ in full Geheime Staatspolizei (German:  �Secret State Police�) Political police of Nazi Germany. It was created by  Hermann Goring in 1933 from the political and espionage units of the  Prussian police and by Heinrich Himmler from the police of the remaining  German states. Himmler was given command in 1934. The Gestapo oper�  ated without civil restraints, and its actions were not subject to judicial  appeal. Thousands of Jews, leftists, intellectuals, trade unionists, politi�  cal clergy, and homosexuals disappeared into concentration camps after  being arrested by the Gestapo. In World War II the Gestapo suppressed  partisan activities in the occupied territories, and a section of the Gestapo  under Adolf Eichmann organized the deportation of Jews to the extermi�  nation camps in Poland.</p><p>Gesualdo \ja-'swal-do\, Carlo, prince of Venosa (b. March 8,  1566, Venosa �d. Sept. 8, 1613, Naples) Italian composer. Nobly born,  he was a passionate musical dilettante. In 1590 he had his first wife and  her lover (a duke) murdered, which earned him great notoriety but no  punishment. His later marriage to the duke of Ferrara�s niece made the  cosmopolitan Ferrara court his second home. His steadily deepening mel�  ancholia was reflected in his music, which included some 125 madrigals  and about 75 sacred vocal works. His six books of madrigals were pub�  lished between 1594 and 1611 in part-books and in 1613 in score. Those  in the last two books are unusual for their dramatic exclamations, dis�  continuous texture, and harmonic license. His extreme chromaticism and  abrupt changes in tempo and dynamics, exaggerating such traits in the  madrigals of his time, would have no rival until the 20th century.</p><p>get Jewish divorce document written in Aramaic and obtained from a  rabbinic court.

According to Christian tradition, it is where  Jesus prayed after the Last Supper and before his arrest and Crucifixion.  The name Gethsemane originates from a Hebrew term meaning �oil  press,� suggesting that the garden was a grove of olive trees. Though its  exact location cannot be determined, Armenian, Greek, Latin, and Rus�  sian churches have accepted an olive grove on the western slope of the  Mount of Olives as the site.</p><p>Getty, J(ean) Paul (b. Dec. 15, 1892, Minneapolis, Minn., U.S.�d.  June 6, 1976, Sutton Place, Surrey, Eng.) U.S. oil billionaire, reputed to  be the richest man in the world at his death. The son of an oil million�  aire, he began buying and selling oil leases in Oklahoma in 1913. He  acquired Pacific Western Oil Corp. in 1932 and soon gained control of  several independent oil companies. He renamed his oil concern Getty Oil  Co. in 1956. His most lucrative venture was a 60-year oil concession in  Saudi Arabia. His financial empire eventually encompassed some 200  enterprises. A zealous art collector, he founded the J. Paul Getty Museum  near Malibu, Calif., in 1953.</p><p>Getty Museum, J. Paul Museum established by Jean Paul Getty to  house his large collection of artworks, to which he continued to add. The  original museum occupied a wing added to his ranch house in Malibu,  Calif., U.S. His collections soon outgrew that location, and in 1974 they  were moved to a new building in Malibu, a lavish re-creation of a Roman  villa uncovered at Herculaneum. On Getty�s death the museum became  the most richly endowed in the world. It now is housed in the Getty Cen�  ter, a striking six-building complex in Los Angeles designed by Richard  Meier, which opened with great publicity in 1997. Its collections include  European paintings, sculpture, drawings, and decorative arts to 1900, illu�  minated manuscripts, and photographs. Greek and Roman antiquities  remain in the Malibu villa. The collections reflect Getty�s preference for  paintings of the Renaissance and the Barcx^ue period and for French fur�  niture.</p><p>Getty Trust, J. Paul Private operating foundation founded in 1953 by  Jean Paul Getty to establish the J. Paul Getty Museum. Originally located  in Malibu, Cal., it now occupies five buildings in the Getty Center in Los  Angeles, each building housing one of the institutes it established when  it diversified its activities in 1983. One institute develops computerized  databases on art-historical information; the others support art restoration  and conservation, interdisciplinary research in art history and the related  humanities, art education, and training in museum management. The  Getty Grants Program supports projects around the world involving the  history and understanding of art and its conservation.</p><p>Gettysburg Town (pop., 2000: 7,490), southern Pennsylvania, U.S.  The site of a momentous American Civil War battle (see Battle of Gettys�  burg), the town and the surrounding area are now in Gettysburg National  Military Park, which preserves 3,865 acres (1,564 hectares), including the  battlefield. The Soldiers� Monument in Gettysburg National Cemetery  marks the spot where Pres. Abraham Lincoln delivered his Gettysburg  Address. The site includes more than 1,200 Civil War monuments, mark�  ers, and tablets.</p><p>Gettysburg Address (Nov. 19, 1863) Speech by Pres. Abraham Lin�  coln at the dedication of a cemetery at Gettysburg, Pa., for those killed  at the Battle of Gettysburg during the American Civil War. The main  address was delivered by the renowned orator Edward Everett (1794-  1865) and lasted two hours. Lincoln�s brief speech, honouring the Union  dead and the principles of democracy and equality they died for, lasted  two minutes. Soon recognized as an extraordinary piece of prose poetry,  it remains one of the most famous speeches ever delivered in the U.S.</p><p>Gettysburg, Battle of (July 1-3, 1863) Major engagement in the  American Civil War at Gettysburg, Pa., regarded as the war�s turning point.  After defeating Union forces at the Battle of Chancellorsville, Robert E. Lee  decided to invade the North with 75,000 troops. When he learned that the  Union�s Army of the Potomac had a new commander, George Meade, he  led his own troops to Gettysburg, a strategic crossroads. On the first day  of battle, Meade�s advance force under John Buford held the site until  reinforcements arrived. On the second day, the Confederates attacked  Union lines at Little Round Top, Cemetery Hill, Devil�s Den, the Wheat-  field, and the Peach Orchard. On the third day, Lee sent 15,000 troops to  assault Cemetery Ridge, held by 10,000 Union troops under Winfield S  Hancock. A Confederate spearhead broke through the Union artillery  defense but was stopped by a fierce Union counterattack on three sides.</p><p>At night under cover of a heavy rain on July 4, Lee led his troops back  to Virginia; Meade was later criticized for not pursuing him. Losses  totaled about 23,000 casualties among 88,000 Union troops and over  20,000 casualties among 75,000 Confederates.</p><p>Getz, Stan orig. Stanley Gayetzby (b.

Getz  was influenced by Lester Young and became known for his light tone and  ethereal approach while performing as one of the �Four Brothers� of  Woody Herman�s Second Herd (1947-49). With the advent of the cool  jazz of the 1950s, he began to dominate jazz popularity polls, and his  incorporation of Brazilian bossa nova music in the early 1960s brought  him to a wider public and commercial success.</p><p>Geulincx \'gce-liqks\, Arnold known as Philaretus \ l fi-lo- , re-t3s\ (b.  Jan. 31, 1624, Antwerp, Spanish Netherlands�d. November 1669,  Leiden, Neth.) Flemish metaphysician and logician. He taught at the Uni�  versity of Louvain from 1646 but was dismissed in 1658, probably  because of his sympathy with Jansenism. He took refuge at Leiden, where  he became a Calvinist. He lived in poverty until 1662, when he obtained  a position at the University of Leiden. He was a major exponent of the  doctrine known as occasionalism. His major works include On Virtue  (1665), Know Thyself (1675), and True Metaphysics (1691).</p><p>geyser \'gI-zor\ (Icelandic geysir, �to rush forth�) Any hot spring that  discharges jets of steam and water intermittently, generally associated  with recent volcanic activity and produced by the heating of underground  waters that have come into contact with, or are very close to, magma.  Geyser discharges as high as 1,600 ft (500 m) have been recorded, but  160 ft (50 m) is much more common (e.g.. Old Faithful in Yellowstone  National Park). Occasionally, a geyser will adopt an extremely regular  and predictable pattern of intermittent activity and discharge for a few  minutes every hour or so.</p><p>Gezira Vjo-'ze-roV or Al-JazTrah N.al-jo-'ze-roV Region, east-central  Sudan. Southeast of the confluence of the Blue Nile and the White Nile  rivers, it is the site of one of the largest irrigation projects in the world.  Begun by the British in 1925, the project distributes the waters of the  Blue Nile through a 2,700-mi (4,300-km) network of canals and ditches.  It has made the region the most productive agricultural area of The Sudan.</p><p>Ghadamis or Ghudamis \g9-'da-mis\ Oasis and town (pop., latest  est.: 15,900), northwestern Libya. Located near the Libyan-Algerian bor�  der, it is at the junction of ancient Saharan caravan routes. It was the Roman  stronghold Cydamus (whose ruins remain), and an episcopal see under the  Byzantine Empire; columns of a Christian church still remain in the Sid!  Badri Mosque. A centre for the Arab slave trade through the 19th century,  it is now a caravan depot linked to the Mediterranean Sea coast.</p><p>Ghaghara River Yga-gs-r q\ formerly Gogra \'go-gra\ Nepali Kar-  nali \kar-'na-le\ River, northern India, Nepal, and China. A major tribu�  tary of the Ganges, it rises as the Karnali in the Tibetan Himalayas and  flows southeast into Nepal. Cutting south across the Siwalik Hills, it splits  into two branches, to rejoin in India and form the Ghaghara proper. It  flows southeast to enter the Ganges after a 600 mi (970 km) course.  Together with the Ganges and its tributaries, it formed the vast alluvial  plain of northern Bihar. Along its lower course it is also called the Sarju  River and the Deoha.</p><p>Ghana Yga-no\ officially Republic of Ghana formerly Gold  Coast Country, West Africa. Area: 92,098 sq mi (238,533 sq km). Popu�  lation (2005 est.): 21,946,000. Capital: Accra. Ghana is home to Akan,  Mossi, Ewe, and Ga-Adangme peoples. Languages: English (official),  Akan, Ewe, Hausa. Religions: Christianity (Protestant, other Christians,  Roman Catholic), traditional beliefs, Islam. Currency: cedi. The land is  generally flat, dominated by the Volta River basin. The north is character�  ized by grassland plains; the south is heavily forested. The southern  coastal plain is the historical Gold Coast. The varied wildlife includes  lions, leopards, and elephants. Ghana has a developing mixed economy  based largely on agriculture and mining. Cacao is the mainstay of the  economy; mineral exports include gold and diamonds. Ghana is a repub�  lic with one legislative house; its head of state and government is the  president. The modem state is named for the ancient Ghana empire that  flourished until the 13th century ad in the western Sudan, about 500 mi  (800 km) northwest of the modern state. The Akan peoples then founded  their first states in modern Ghana. Gold-seeking Mande traders arrived by  the 14th century and Hausa merchants by the 16th.

The Asante (Ashanti), an  Akan people, originated in the central for�  est region and formed a strongly central�  ized empire that was at its height in the 18th�19th century. European  exploration of the region began early in the 15th century, when the Por�  tuguese landed on the Gold Coast; they later established a settlement at  Elmina as headquarters for the slave trade. By the mid-18th century the  Gold Coast was dominated by numerous forts controlled by Dutch, Brit�  ish, and Danish merchants. Britain made the Gold Coast a crown colony  in 1874, and British protectorates over the Asante and the northern ter�  ritories were established in 1901. In 1957 the Gold Coast became the  independent state of Ghana. Since independence several political coups  have occurred, but the coup of 1981 produced a government that lasted  into the 1990s and made a smooth transition into another administration  at the beginning of the 21st century.</p><p>Ghana empire First of the great medieval trading empires of western  Africa (7th-13th century). Located in what is now southeastern Mauri�  tania and part of Mali, it acted as intermediary between Arab and Berber  salt traders to the north and gold and ivory producers to the south. Gold  was secured through barter from those living at the empire�s southern limit  and exchanged in the capital for commodities, especially salt. As the  empire grew richer it extended its reach, incorporating gold-producing  southern lands and cities to the north. The king exacted tribute from the  princes of subject tribes. Ghana began to decline with the rise of the Mus�  lim Almoravids; the Almoravid leader Abu Bakr seized the Ghanaian capi�  tal of Kumbi in 1076. The empire�s subject peoples began to break away,  and in 1240 the empire�s remains were incorporated into the Sundiata  empire of Mali.</p><p>Ghannouchi \gan-'nu-she\, Rachid al- also spelled Rashid  al-Ghannush?

In 1981 he helped  organize the Islamic Tendency Movement, which later became Hizb  al-Nahdah; this action resulted in his imprisonment (1981-84, 1987-88).  In 1993 Britain granted him political asylum.</p><p>Ghats VgotsV Eastern and Western Two mountain ranges form�  ing the edges of the Deccan plateau in southern India. The Eastern Ghats  extend about 700 mi (1,100 km) along the southeastern and eastern coast  north to the mouth of the Mahanadi River; their average elevation is about  2,000 ft (600 m). The Western Ghats run some 800 mi (1,300 km) along  the southwestern and western coast north to the mouth of the Tapti River;</p><p>their average elevations range from 3,000 ft (900 m) to 5,000 ft (1,500  m).

A spiritual crisis prompted him  to abandon his career in 1095 and adopt the life of a poor Sufi. He did  not return to teaching until 1106, persuaded by those who believed he  was a centennial renewer of Islam. His great work, Ihyd * 'ulum al-din  (�Revival of the Religious Sciences�), explained Islamic doctrines and  practices and traced their connection with Sufi mysticism.</p><p>Ghazan \ga-�zan\, Mahmud (b.

In 1284 his father, the ruler Arghun, made him viceroy of northeast�  ern Persia, where he defended the frontier against the Chagatai Mongols.  In 1295 he converted from Buddhism to Islam before taking the throne.  He successfully fought his family�s enemy, the MamlOk dynasty, in Syria,  defeating their army at Hims. The Mamluks reoccupied Syria on his  departure. Despite three more attempts to regain the city, he was unable  to do so. He spoke many languages and was said to have been learned in  a variety of fields. He commissioned his famous vizier, Rashid al-Dln, to  compose a history of the Mongols, which was later expanded to include  information on all those with whom the Mongols had come in contact.</p><p>ghazel or ghazal or gazel Vgoz-ul ,\ Arabic Vga-zal\ In Islamic lit�  erature, a lyric poem, generally short and graceful in form and typically  dealing with love.

One of the chief towns of the medieval county of Flanders, Ghent was  one of the largest towns in northern Europe by the 13th century. Its pros�  perity was based on its manufacture of luxury cloths, which were famous  throughout Europe. It began to decline in the late 16th century, when its  cloth was unable to compete with England�s. Its economy revived with the  introduction of cotton-spinning machinery (in particular, a power loom  smuggled out of England), and it subsequently became the centre of the  Belgian textile industry. Ghent has many fine museums, notably the  Museum of Fine Arts, which contains a treasury of paintings by Flemish  masters who lived and worked in Ghent during the 16th and 17th centuries.

After purging the party of rivals closely iden�  tified with Soviet policies, he became prime minister (1952-55) and  gradually adopted economic and foreign policies that served Romania�s  national interests. As president of the State Council (1961-65), he pur�  sued a program of industrialization, despite the objections of other Soviet-  bloc countries that wanted Romania to remain agricultural. He further  demonstrated Romania�s independence by forming cordial relations with  noncommunist nations and with China.</p><p>Gherardo delle Notte See Gerrit van Honthorst</p><p>ghetto Formerly, a street or quarter of a city set apart as a legally  enforced residential area for Jews. Forced segregation of Jews spread  throughout Europe in the 14th-15th centuries. Ghettos were customarily  enclosed with walls and gates and kept locked at night and during Chris�  tian festivals. Since outward expansion was usually impossible, most  ghettos grew upward; congestion, fire hazards, and unsanitary conditions  often resulted. Ghettos were abolished in western Europe in the 19th cen�  tury; those revived by the Nazi Party (see Warsaw Ghetto Uprising) were  overcrowded holding places preliminary to extermination. More recently,  the term ghetto has been applied to impoverished urban areas exclusively  settled by a minority group or groups and perpetuated by economic and  social pressures rather than legal and physical measures.</p><p>Ghibellines See Guelphs and Ghibellines</p><p>Ghiberti \ge-'ber-te\, Lorenzo (b. c. 1378, Pelago�d. Dec. 1, 1455,  Florence) Italian sculptor, goldsmith, and designer active in Florence. He  was trained as a goldsmith and painter. In 1402 he won a competition for  the commission to make a pair of bronze doors for the Baptistery of Flo�  rence Cathedral, defeating Filippo Brunelleschi. The honour brought him  immediate fame and prominence. Work on the doors lasted from 1403 to  1424. In 1425 he was asked to make a second pair, known as the Gates  of Paradise, which he completed in 1452. The reliefs on the first door are  the major sculptural works of the International Gothic style in Italy; those  on the second, in a more advanced style, are among the finest examples  of Italian Renaissance art. Among his other commissions were three bronze  statues for Or San Michele (1413-29) and two reliefs for the Baptistery  of Siena Cathedral (1417-27). He directed a large workshop with many  assistants, including Donatello and Paolo Uccello. His treatise on art his�  tory and theory includes the earliest surviving autobiography of an artist.</p><p>Ghirlandaio X.gir-bn-'da-yoX, Domenico orig.

In 1481-82 he painted several frescoes, includ�  ing the Calling of Sts. Peter and Andrew in the Vatican�s Sistine Chapel.  His greatest fresco cycle, commissioned by an agent of the Medici, was  painted in the choir of Santa Maria Novella in Florence (1485-90); depict�  ing scenes from the lives of the Virgin and St. John the Baptist in con�  temporary dress against detailed patrician interiors, it has become a major  source of current knowledge on the furnishings of a late 15th-century  Florentine palace. With his two brothers he directed one of the most pros�  perous workshops in Florence; they also produced numerous altarpieces.  His finest portrait is The Old Man and His Grandson (c. 1480-90).</p><p>ghost Soul or specter of a deceased person. Belief in ghosts has been  common since ancient times and is reflected in folklore around the world.  It is based on the notion that the spirit is separable from the body and can  continue its existence after the death of the body. Ghosts are believed to  inhabit the netherworld and to be capable of returning to the world of the  living, appearing as living beings or in a nebulous likeness of the  deceased. They are thought to be especially likely to haunt places or  people connected with some strong emotion of their past life, such as fear,  remorse, or the terror of a violent death. The traditional visual manifes�  tations of haunting include ghostly apparitions, the movement of objects,  or the appearance of strange lights; auditory signs include disembodied  laughter and screams, knocking, or footsteps.</p><p>Ghost Dance Nineteenth-century Native American cult. It represented  an attempt by Indian peoples in the western U.S. to rehabilitate their tra�  ditional cultures. The Ghost Dance arose in 1889, when the Paiute prophet-</p><p>dreamer Wovoka announced the imminent return of the dead (hence  �ghost�), the ousting of the whites, and the restoration of Indian lands,  food supplies, and way of life, all of which would be hastened by dances  and songs revealed in Wovoka�s spiritual visions. The Ghost Dance spread  rapidly. It coincided with the Sioux outbreak of 1890, which culminated  in the massacre at Wounded Knee, where the �ghost shirts� failed to pro�  tect the wearers as promised by Wovoka. The cult soon became obsolete.</p><p>Ghudamis See Ghadamis</p><p>Ghulam Ahmad \'gu-lam-'ak-mad\, MTrza (b. c. 1839, Qadian,  India�d. May 26, 1908, India) Indian Muslim leader, founder of the  Ahmadiyyah sect. Born into a prosperous family, he led a life of contempla�  tion and religious study. Claiming in 1889 to have had a special revelation  from God, he gathered a small band of disciples. He declared himself to be  the mahdi and the reincarnation of Muhammad, Jesus, and Krishna. He was  opposed by the orthodox Muslim community, but a number of his teachings  became the basis of the beliefs of the Ahmadiyyah. He attempted to estab�  lish missionary organizations and schools on the Christian model but did  not try to reconcile Christian and Muslim doctrine.</p><p>Gl Bill (of Rights) or Servicemen's Readjustment Act (1944)  U.S. legislation that provided benefits to World War II veterans. Through  the Veterans Administration (VA), the bill provided grants for school and  college tuition, low-interest mortgage and small-business loans, job train�  ing, hiring privileges, and unemployment payments. Amendments to the  act provided for full disability coverage and the construction of additional  VA hospitals. Later legislation extended the benefits to all who had served  in the armed forces.</p><p>Giacometti \ja-k3-'me-te\, Alberto (b. Oct. 10, 1901, Borgonovo,  Switz.�d. Jan. 11, 1966, Chur)</p><p>Swiss sculptor and painter. His father  was a Post-Impressionist painter, and  his brother Diego was a well-known  furniture designer. After studying art  in Geneva (1919-20) and Paris  (1922-25), he developed a style  related to the Cubist sculpture of  Alexander Archipenko and the post-  Cubist work of Jacques Lipchitz. His  work also showed the influence of  African and Oceanic art. After  experimenting with abstraction in  the 1930s, he became increasingly  focused on finding ways to capture a  sense of reality in sculpture. For Gia�  cometti an artwork was to become an  almost existential evocation of real�  ity. By the 1940s he had developed  his signature style, producing thin,  attenuated sculptures of solitary,  skeletal figures and heads. He  became well known, especially in  the U.S., through two exhibitions in  New York City (1948, 1950) and an essay on his art by Jean-Paul Sartre.  In 1963 he designed a stage set for a production of a Samuel Beckett play.</p><p>Giambologna \jam-bo-'lon-ya\ or Giovanni da Bologna or  Jean Boulogne \bii-'16n y \ (b. 1529, Douai, Spanish Neth.�d. Aug. 13,  1608, Florence) Flemish-born Italian sculptor. After studies under Jacques  Dubroeucq, he went to Rome in 1550, where his style was influenced by  Hellenistic sculpture and the works of Michelangelo; he settled in Florence  in 1552. He produced many of his most important works for the Medici  family, but it was the Fountain of Neptune (1563-66) in Bologna that made  him famous. His bronze equestrian statue of Cosimo I (1587-93), the first  of its kind made in Florence, became a pattern for similar statues all over  Europe. His garden sculptures�notably for Florence�s Boboli Gardens  and for three Medici villas, including the colossal Apennine (1570-80) at  Pratolino�enjoyed great popularity. He was also a prolific manufacturer  of bronze statuettes; many of his working models still survive. He was the  outstanding sculptor of Italian Mannerism.</p><p>Giannini \je-9-'ne-ne\, A(madeo) P(eter) (b. May 6, 1870, San  Jose, Calif., U.S.�d. June 3, 1949, San Mateo, Calif.)

Pear- or beet-shaped, the cells have two nuclei  and eight flagella and attach with a sucking organ to human intestinal  mucous membranes. They cause the disease giardiasis. Generally spread  when traces of human feces containing the parasite are ingested, giardia�  sis is most common among children in close contact with other children,  but it also occurs among adults. Diarrhea, pain, and distension of the  stomach may occur. It is common wherever there is contamination of  domestic or surface water in lakes, rivers, and reservoirs, and it is a major  cause of diarrhea worldwide. Beaver feces are often responsible for gia�  rdiasis among campers who take water from lakes and rivers.</p><p>gibbon Vgi-banN Any of about six species (genus Hylobates) of lesser  APES (family Hylobatidae), found in  Indo-Malayan forests.

Jan. 16, 1794, London)</p><p>British historian. Educated at the  University of Oxford and in Switzer�  land, Gibbon wrote his early works  in French. In London he became a  member of Samuel Johnson�s bril�  liant intellectual circle. On a trip to  Rome he was inspired to write the  history of the city. His Decline and  Fall of the Roman Empire, 6 vol. (1776-88), is a continuous narrative  from the 2nd century ad to the fall of Constantinople in 1453. Though  Gibbon�s conclusions have been modified by later scholars, his acumen,  historical perspective, and superb literary style have given his work its  lasting reputation as one of the greatest historical works.</p><p>Gibbons, Orlando (b. 1583, Oxford, Oxfordshire, Eng.�d.

Son of a musi�  cian, he became organist of the Chapel Royal c. 1605 and remained there  the rest of his life, serving also as organist at Westminster Abbey for his  last two years. A versatile composer, he wrote several Anglican services,</p><p>some 40 anthems, about 50 secular keyboard pieces, about 35 fantasias  for chamber ensembles, and some 15 madrigals.</p><p>Gibbons v. Ogden U.S. Supreme Court decision (1824) that estab�  lished that states could not, by legislative enactment, interfere with the  power of Congress to regulate interstate commerce. The state of New York  had authorized a monopoly on steamboat operation in its waters, an action  upheld by a state chancery court, but the Supreme Court ruled that com�  peting steamboat operators were protected by the terms of a federal license  to engage in trade along a coast. The decision, an important development  in the interpretation of the commerce clause of the U.S. Constitution, freed  all navigation from monopoly control.</p><p>Gibbs, J(osiah) Willard (b. Feb. 11, 1839, New Haven, Conn.,  U.S.�d. April 28,1903, New Haven) U.S. theoretical physicist and chem�  ist. He became the first person to earn an engineering doctorate from Yale  University, where he taught from 1871 until his death. He began his career  in engineering but turned to theory, analyzing the equilibrium of James  Watt�s steam-engine governor. His major works were on fluid thermody�  namics and the equilibrium of heterogeneous substances, and he devel�  oped statistical mechanics. Gibbs was the first to expound with  mathematical rigour the �relation between chemical, electrical, and ther�  mal energy and capacity for work.� Though little of his work was appre�  ciated during his lifetime, his application of thermodynamic theory to  chemical reactions converted much of physical chemistry from an empiri�  cal to a deductive science, and he is regarded as one of the greatest U.S.  scientists of the 19th century.</p><p>Gibbs, William Francis (b. Aug. 24, 1886, Philadelphia, Pa.,  U.S.�d. Sept. 6, 1967, New York, N.Y.) U.S. naval architect. He initially  studied law but turned to naval architecture, studying for a year in seclu�  sion, and with his brother Frederick H. Gibbs designed a transatlantic  liner. During World War I they designed ships for the U.S. government,  and after the war they were commissioned to recondition the Leviathan.  Gibbs�s design for the Malolo (1927), with its numerous watertight com�  partments and other safety features, became an industry standard. In 1940  he designed a cargo ship suitable for mass production; using prefabrica�  tion techniques, he reduced production time from as long as four years  to as little as four days, an innovation of enormous value in World War  II. His passenger liner United States (1952) set speed records in transat�  lantic service.</p><p>Gibeon Ygi-be-onX Ancient city of Canaan. It is located north of Jerus�  alem at modem Al-Jib in the West Bank. According to the Bible, its inhab�  itants made an alliance with the Israelite military leader Joshua during his  conquest of Canaan but were instead made slaves. Excavations in 1956  by a U.S. expedition revealed that the site had been occupied during the  Early and Middle Bronze Ages and in the latter part of the Late Bronze  Age, just before Joshua�s conquest of Canaan; the town then was a depen�  dency of Jerusalem and was probably not fortified.</p><p>Gibraltar \j9-'brol-t3r\ British colony, on the Mediterranean coast of  southern Spain.

Captured by the British in 1704, it became a British crown  colony in 1830. Gibraltar was an important port in World Wars I and II.  The sovereignty of the territory has remained a source of constant fric�  tion between the United Kingdom and Spain, though residents voted in  1967 to remain part of Britain. Spain lifted its border blockade in the  mid-1980s. Perhaps its most famous residents are the Barbary macaques,  who occupy many of Gibraltar�s caves and are Europe�s only free-living  monkeys.</p><p>Gibraltar, Strait of ancient Fretum Herculeum Channel, con�  necting the Mediterranean Sea with the Atlantic Ocean.

As a right-handed pitcher for the St. Louis  Cardinals (1961-75) who was at his best in crucial games, Gibson won  seven of the nine World Series games in which he pitched. In 1968 he  started 34 games, completed 28, and had an earned run average of 1.12.  He pitched quickly, and his best pitches were a fastball and a slider. Dur�  ing his career he had 3,117 strikeouts, making him the first pitcher to  accumulate more than 3,000 since Walter Johnson in the 1920s.</p><p>Gibson, Charles Dana (b.

His �Gibson girl� drawings, relying on his wife  as a model, defined the U.S. ideal of spirited feminine beauty at the turn  of the century, and his refined pen-and-ink style was widely imitated.  Collier�s reportedly paid him the unprecedented sum of $50,000 to pro�  duce a double-page illustration every week for a year. He also published  several collections of satirical drawings of high society.</p><p>Gibson, Eleanor J(ack) orig. Eleanor Jack (b. Dec. 7, 1910, Peo�  ria, Ill., U.S.�d. Dec. 30, 2002, Columbia, S.C.)

In her major work, Principles of Perceptual Learning and Development  (1969), she proposed that perceptual learning is a process of discovering  how to transform previously overlooked potentials of sensory stimulation  into effective information. In books such as The Psychology of Reading  (1975), she also contributed to studies of the reading process. She received  the National Medal of Science in 1992. James J.

He taught at Smith College (1928-49) and Cornell University (1949-72).  He is best known for his adherence to realism and his extensive experi�  mental studies of visual perception explicating that view. In his first major  work, The Perception of the Visual World (1950), he proposed that per�  ception is unmediated by associations or information processing but rather  is direct. He argued for an examination of the organism�s dynamic world  in search of the information that specified the state of that world. He</p><p>developed his position in The Senses Considered as Perceptual Systems  (1966) and The Ecological Approach to Visual Perception (1979). His  followers organized the International Society for Ecological Psychology.  Eleanor J. Gibson was his wife.</p><p>Gibson, Josh in full Joshua Gibson (b. Dec. 21, 1911, Buena Vista,  Ga., U.S.�d.

Grays (1930-31, 1937-46).  Though precise records do not exist, he is believed to have led the Negro  leagues in home runs for 10 consecutive seasons and to have had a career  batting average of .347. His catching ability was praised by major-league  stars against whom he played in exhibition games.

With his first novel, Neuromancer (1984), he emerged  as a leading exponent of cyberpunk, a school of science fiction whose  works are characterized by countercultural antiheroes trapped in a dehu�  manized, high-tech future. His concept of cyberspace (a term he coined),  a computer-simulated reality, is a major contribution to the genre. His later  books include Count Zero (1986), Burning Chrome (1986), Mona Lisa  Overdrive (1988), The Difference Engine (1990; with Bruce Sterling), and  Virtual Light (1993).</p><p>Gibson Desert Arid zone, Western Australia.

He briefly attended  Massachusetts Institute of Technology, then worked briefly for the firm  of McKim, Mead &amp; White. For some years his 60-story Woolworth Build�  ing (1910-13) in New York City, with its Gothic detail in terra-cotta over  a steel frame, was regarded as a model of tall commercial building design  (it was for years the tallest building in the world). Other works include  the U.S. Supreme Court Building, Washington, D.C. (completed 1935),  and the campuses of the universities of Minnesota and Texas. Though not  highly original, Gilbert was an acknowledged leader of his profession in  the U.S. during a period in which monumental architecture predominated.</p><p>Gilbert, Sir Humphrey (b. c. 1539�d. September 1583, at sea near  the Azores) English soldier and navigator. The half brother of Sir Walter  Raleigh, he proposed in his Discourse (1566) a voyage in search of the  Northwest Passage. Queen Elizabeth I rejected the idea and sent him to Ire�  land (1567-70), where he ruthlessly suppressed an uprising, for which he  was knighted. In 1578 he set out with seven ships, intending to colonize  North America, but through his poor leadership some ships returned to  England and others turned to piracy. He sailed again in 1583, this time  arriving in Newfoundland, which he claimed in the name of the queen.</p><p>Gilbert, Sir W(illiam) S(chwenck) (b. Nov. 18, 1836, London,  Eng.�d. May 29, 1911, Harrow Weald, Middlesex) British librettist. His  early ambition was for a legal career, but in 1861 he began to publish  comic ballads, illustrated by himself and signed �Bab.� In 1870 he met  Arthur Sullivan, and they soon produced the light opera Thespis (1871),  which was followed by Trial by Jury (1875) and four productions staged  by Richard D�Oyly Carte: The Sorcerer (1877), H.M.S. Pinafore (1878),  The Pirates of Penzance (1879), and Patience (1881). Carte built the  Savoy Theatre in 1881 for productions of the partners� work, which  became known as the �Savoy Operas�; these later operettas included  Iolanthe (1882), Princess Ida (1884), The Mikado (1885), Ruddigore  (1887), The Yeomen of the Guard (1888), and The Gondoliers (1889).  Mounting tensions between Gilbert and Sullivan led to a break, but they  reunited in 1893 to produce Utopia Limited and later The Grand Duke  (1896). Gilbert died of a heart attack brought on while rescuing a woman  from drowning. His lyrics include some of the finest comic verse ever  written in English.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Gilbert and Ellice Islands &#x25BA; ginkgo I 763</p><p>Gilbert and Ellice Islands Former British colony, western central  Pacific Ocean. The colony consisted of the Gilbert Islands, Tuvalu (formerly  Ellice islands), the northern Line Islands, and the Phoenix Islands. First vis�  ited by Europeans by the early 19th century, the group was proclaimed a  British protectorate in 1892 and made a crown colony in 1916.

The British visited them in the 18th and 19th centuries, and in 1892 they  became a British protectorate. In 1916 they became part of the Gilbert  and Ellice Islands crown colony. They were occupied by Japanese forces  from 1941 to 1943 and saw heavy fighting.

Dec. 16, 1935, England) British metallurgist. In 1876�  77, with his cousin Sidney Gilchrist Thomas (1850-85), he devised the  basic Bessemer process of making steel in Bessemer converters from  phosphorus-containing pig iron. In the Thomas-Gilchrist process, the lin�  ing used in the converter is basic rather than acidic, and it captures the  acidic phosphorus oxides formed upon blowing air through molten iron  made from the high-phosphorus iron ore prevalent in Europe. The pro�  cess subsequently became widely used.</p><p>Gilead Vgi-le-3d\ Area of ancient Palestine, east of the Jordan River.  Now northwestern Jordan, it was bounded to the north by the Yarmuk  River and to the southwest by what were known then as the plains of  Moab. Sometimes the name is used in a more general sense to describe  the entire region east of the Jordan River and west of the Arabian Desert.  The name first appears in the biblical account of the last meeting of Jacob  and Laban (Gen. 31:21-22). The scene of the battle between Gideon and  the Midianites, it was also the home of the prophet Elijah.</p><p>Gilgamesh Vgil-go-.mesh, gil-'ga-moshV Hero of the ancient Akkadian-  language Epic of Gilgamesh. The great literary work of ancient Mesopot�  amia, the epic is known from 12 incomplete tablets discovered at Nineveh  in the library of Ashurbanipal. Gaps in the narrative have been filled in  with fragments found elsewhere. The character Gilgamesh is probably  based on the Gilgamesh who ruled Uruk in the 3rd millennium bc. The  epic presents Gilgamesh as a great warrior and builder, who rejects the  marriage proposal of the goddess Ishtar. With the aid of his friend and  companion Enkidu, he kills the divine bull that Ishtar sends to destroy him.  Enkidu�s death prompts Gilgamesh to seek Utnapishtim, survivor of the  legendary flood, to learn how to escape death. He obtains a youth-  renewing plant only to have it stolen. The epic ends with the return of the  spirit of Enkidu, who gives a dismal report on the underworld.</p><p>Gill, Brendan (b. Oct. 4, 1914, Hartford, Conn., U.S.�d. Dec. 27,  1997, New York, N.Y.)

Gillespie was influ�  enced by Roy Eldridge and played  with the big bands of Cab Calloway,</p><p>Earl Hines, and Billy Eckstine before  leading small groups in the mid-  1940s. He pioneered bebop with  saxophonist Charlie Parker and pia�  nist Thelonious Monk. Bringing this  approach to his big band in the late  1940s, Gillespie popularized the use  of Afro-Cuban rhythms in jazz. He alternated between large and small  ensembles for the rest of his career. His virtuosity and comic wit (in addi�</p><p>tion to his puffed cheeks and trademark 45� upturned trumpet bell) made  him one of the most charismatic and influential musicians in jazz.</p><p>Gilman, Charlotte (Anna) Perkins (Stetson) (b.

In her best-known work, Women and  Economics (1898), she proposed that women�s sexual and maternal roles  had been overemphasized to the detriment of their social and economic  potential and that only economic independence could bring true freedom.  Her other works include the celebrated short story �The Yellow Wallpa�  per� (1899).</p><p>Gilmore, Patrick (Sarsfield) (b. Dec. 25, 1829, County Galway,  Ire.�d. Sept. 24, 1892, St. Louis, Mo., U.S.) Irish-born U.S. bandmas�  ter. He immigrated to the U.S. at age 19. In 1859 he took over the Bos�  ton Brigade Band (later known as Gilmore�s Band). During the Civil War,  the entire band enlisted in the Union army. A flamboyant showman,  Gilmore organized extravaganza performances in 1869 and 1872 with  more than 10,000 performers; the first featured cannon fire and 100 fire�  men beating anvils, and the second employed a chorus of 20,000. From  1872 until his death he led the New York 22nd Regiment Band, giving  150 concerts in Europe in 1878. His innovations reduced the heavy reli�  ance on brass instruments in favour of the higher proportion of reeds  characteristic of modern concert bands.</p><p>gin Colorless distilled liquor. Made from neutral grain spirits, it acquires  its distinctive flavour from juniper berries and aromatics (such as anise and  caraway seeds). Its origin is attributed to a 17th-century Dutch medical  researcher, Franciscus Sylvius. Two principal types are marketed: a malty-  flavoured and full-bodied Netherlands type (alcohol content about 35%  by volume) and a dry, purified type favoured in Britain and the U.S. (40-  47% alcohol by volume). Dry gin, which has more flavouring ingredients,  is served either unmixed or in cocktails.

His epic  poem Howl (1956), a denunciation of the failings of American society,  became the most famous poem of the Beat movement; in it and later works,  largely inspired by Walt Whitman, he celebrated the pleasures of psycho�  tropic drugs, footloose wandering, and homosexuality. Kaddish (1961) is  a long confessional poem about his mother�s insanity and suicide. His  collections include Reality Sandwiches (1963), The Fall of America  (1972), and Mind Breaths (1978).

From 1972 to 1980 she taught  at Columbia, where she became the first tenured female professor. As  director of the Women�s Rights Project of the American Civil Liberties Union,  she argued six landmark cases on gender equality before the Supreme Court  of the United States. In 1980 she was appointed to the U.S. Court of  Appeals, and in 1993 she was appointed by Pres. Bill Clinton to the  Supreme Court as only its second female justice.

Ordained  a priest (1825), he became court chaplain of Sardinia (1831), but was  briefly imprisoned (1833) for involvement in a republican plot. He exiled  himself to Paris and Brussels, where he published works advocating a  united Italy headed by the pope. He returned to Italy in 1847 and became  premier of Sardinia-Piedmont (1848-49).

As a political leader, he used the technique later  called giolittisma, which emphasized personal deals rather than party loy�  alty, as well as electoral corruption. As prime minister (1892-93), he  instituted reforms but became enveloped in a bank scandal; he cleared  himself but greatly damaged his successor, Francesco Crispi. As minister  of the interior (1901-03) and prime minister (1903-05, 1906-09), he was  both praised and criticized for his calm attitude toward widespread strikes.  In his fourth ministry (1911-14) he oversaw the Italo-Turkish War, then  opposed Italy�s entrance into World War I. In his final term as premier  (1920-21), he undertook Italy�s reconstruction. He tolerated the early  Fascists but in 1924 withdrew his support.</p><p>Giordano \jor-'da-no\, Luca (b. Oct. 18, 1632, Naples�d. Jan. 3,  1705, Naples) Italian painter active in Naples. He was inspired by the  work of Jose de Ribera and (after extensive travel in Florence, Rome, and  Venice) that of Paolo Veronese and Pietro da Cortona, whose influence is  most evident in his huge ceiling fresco in the gallery of the Medici-  Riccardi Palace (1682-85/86), Florence. In 1692 he went to Spain as court  painter to Charles II; his frescoes in El Escorial are considered his best  works of the period. In 1702 he returned to Naples, where he completed  his last great work, the ceiling of the Treasury Chapel of the Certosa di</p><p>San Martino (1704). His oil and fresco output was enormous, and his sub�  ject matter ranged from religious to mythological themes; his nickname  was Luca fa presto (�Luca, work quickly�). Many of his frescoes in  Naples were destroyed or damaged in World War II.</p><p>Giorgione \jor-'j6-ne\ or Giorgio da Castelfranco orig. Gior�  gio Barbarelli (b. c. 1477, Castelfranco Veneto, Republic of  Venice�d. 1510, Venice) Italian painter active in Venice. Nothing is  known of his early life. The technique, colour, and mood of his pictures  suggest that he studied with Giovanni Bellini in Venice in the 1490s. His  major public commission was the execution of frescoes on the exterior  of the German Exchange, now known only through engravings and ruined  fragments. Of the few paintings attributed to Giorgione, two were com�  pleted by other artists after his death, one by Titian. Though almost every  aspect of his work is debated, including the attribution, dating, and inter�  pretation of paintings associated with him, it is clear that he was a pio�  neer in the technique of oil painting on canvas and a master of creating  mood and mystery, as epitomized in The Tempest (c. 1505), a milestone  in Renaissance landscape painting. He had far-reaching influence on por�  traiture; many early 16th-century artists imitated his style.

He decorated chapels and churches in Assisi, Rome,  Padua, Florence, and Naples with frescoes and panel paintings. Because  little of his life and few of his works are documented, attributions and a  stylistic chronology of his paintings remain problematic and often highly  speculative. His works in Rome include the heavily restored mosaic of  Christ Walking on the Water over the entrance to St. Peter�s Basilica, and  an altarpiece from St. Peter�s, now in the Vatican Museum. In Padua, his  fresco of the Last Judgment decorates the western wall of the Arena  Chapel, and the rest of the chapel is covered with his narrative frescoes  featuring scenes from the lives of the Virgin Mary and Christ. Later in  his career he executed frescoes in four chapels in the church of Santa  Croce in Florence, two of which survive. In 1334 he was appointed sur�  veyor of Florence Cathedral; his design for the campanile was altered after  his death. The most important extant panel painting attributed to him is  The Madonna in Glory (c. 1305-10). He achieved great fame in his life�  time, and he is considered the father of European painting for breaking  with the impersonal stylizations of Byzantine art and introducing new  ideals of naturalism and humanity, three-dimensional space, and three-  dimensional form. The course of Italian painting was dominated by his  students and followers. His work points to the innovations of the Renais�  sance style that developed a century later.</p><p>Lamentation, fresco by Giotto, c. 1305-06; in the Arena Chapel, Padua, Italy.</p><p>SCALA/ART RESOURCE</p><p>Giovanni da Bologna See Giambologna</p><p>Giovanni di Paolo \j6-'van-ne-de-'pau-lo\ (di Grazia) (b. c. 1403,  Siena, Republic of Siena�d. 1482, Siena) Italian painter active in Siena.

He settled in Philadelphia during the Ameri�  can Revolution and resumed trading in 1783. He developed an efficient,  worldwide trading fleet and amassed a fortune. In 1812 he bought out the  Bank of the United States, renaming it the Bank of Stephen Girard. Dur�  ing the War of 1812 he purchased government bonds, which by 1814 con�  stituted 95% of the U.S.�s war loan.

In 1666 he received his most famous commission, the Apollo Tended by  the Nymphs, for the Grotto of Thetis at Versailles. Of his other works at  Versailles, the most notable are The Bath of the Nymphs (1668-70) and  The Rape of Persephone (1677-79). Although superficially a Baroque art�  ist, Girardon�s deep-seated Classical tendencies also emerge in the serene  solemnity of his two principal works outside Versailles: an equestrian  statue of Louis XIV (1683-92), destroyed in the French Revolution, and  the tomb of Cardinal Richelieu in the church of the Sorbonne (1675-94).

He made the diplomatic service his career, while becoming known  as an avant-garde writer with early poetic novels such as Suzanne et le  Pacifique (1921). He created an impressionistic form of drama by empha�  sizing dialogue and style rather than realism. In such works as Electre  (1937) and Cantique des cantiques (1938), he sought inspiration in Clas�  sical or biblical tradition. His most famous works are Tiger at the Gates  (1935), about the Trojan War, and The Madwoman of Chaillot (1946).</p><p>girder In building construction, a large main supporting beam, commonly  of steel or reinforced concrete, that carries a heavy transverse (crosswise)  load.

Dec. 28, 1903, Saint-Jean-de-Luz, France) British novelist. He  had a brilliant academic career but an unhappy personal life; twice  involved in miserable marriages, he experienced the life of near poverty  and constant drudgery that he described in New Grub Street, 3 vol. (1891),  his best-known work, and The Private Papers of Henry Ryecroft (1903).  Inspired by Honore de Balzac, he wrote a cycle of 22 novels, which  included Born in Exile (1892) and The Odd Women (1893). His realistic  novels of lower-middle-class life are noted for their acute perception of  women�s social position and psychology.</p><p>Giuliani, Rudolph W(illiam) or Rudy Giuliani (b. May 28,1944,  Brooklyn, New York, N.Y., U.S.) U.S. politician, who was mayor of New  York City from 1994 to 2002. Beginning in 1970, he worked for the U.S.  government, holding positions in the office of the U.S. attorney and in the  Department of Justice. He practiced law privately (1977-81) but returned  to the Justice Department as associate attorney general (1981-83). In 1983  he was appointed U.S. attorney for the Southern District of New York. In  1994 he became New York City�s first Republican mayor in two decades.  Credited with cutting crime, improving the quality of life, and benefiting  business, he won a second term in 1997, though critics charged that he  defended police misconduct and gutted essential programs. After the Sep�  tember 11 attacks in 2001, Giuliani was praised for his strong leadership  of the city through the crisis.</p><p>Giulini \jii-'le-ne. Carlo Maria (b. May 9, 1914, Barletta, Italy�d.

That same year he was appointed musical director for  Italian Radio. In 1950 he organized the Milan Radio Orchestra. After sev�  eral years at La Scala in Milan, he left opera at the peak of his interna�  tional career in 1967; he thereafter devoted his time to conducting  symphony orchestras. His recordings of operas and choral works by Wolf�  gang Amadeus Mozart and Giuseppe Verdi were widely acclaimed, and he  subsequently held important orchestral posts in Chicago (1968-78),  Vienna (1973-76), and, lastly, Los Angeles (1978-84).</p><p>Giulio Romano \'ju-le-6-ro-'ma-no\ orig.

Apprenticed to  Raphael in Rome, on his master�s death he became Raphael�s principal  heir and artistic executor, completing several of Raphael�s important Vat�  ican frescoes. From 1524 he lived in Mantua, where he came to domi�  nate artistic activity at the Gonzaga court and developed a personal, anti-  Classical style. His most important commission, the Palazzo del Te (begun  1526), was one of the first Mannerist buildings to deliberately flout the  tenets of Classical architecture. He achieved great fame in his lifetime,  and his work presaged the illusionistic ceiling painting of the Baroque  PERIOD.</p><p>Givenchy \zhe-va n -'she\, Hubert de (b. Feb. 21, 1927, Beauvais, Fr.)

In 1952 he opened his own house and introduced his  first collection, featuring separates, high-style coats, and elegant ball  gowns. In 1957 he and Cristobal Balenciaga introduced the �sack� silhou�  ette (clothes without waistlines). His designs for Audrey Hepburn in Break�  fast at Tiffany�s (1961) popularized the high-bosomed dress without  sleeves or belt.

It is the focus of Glacier Bay  National Park and Preserve.</p><p>Glacier Bay National Park and Preserve Natural area, south�  eastern Alaska, U.S. Located on the Gulf of Alaska, it was proclaimed a  national monument in 1925, established as a national park and preserve  in 1980, and designated a World Heritage site in 1992. It covers 5,040 sq  mi (13,053 sq km). It includes Glacier Bay, much of Mount Fairweather,  and the U.S. portion of the Alsek River. Among its great tidewater gla�  ciers is Muir Glacier, which rises 265 ft (81 m) above the water and is  nearly 2 mi (3 km) wide. The park also includes a dramatic range of plant  species and such wildlife as brown and black bears, mountain goats,  whales, seals, and eagles.</p><p>Glacier National Park National preserve, northwestern Montana,  U.S. Set in the state�s Rocky Mountains wilderness, it adjoins the Cana�  dian border and Canada�s Waterton Lakes National Park.

In 1891  he met Robert Henri, and he subsequently became a member of The Eight  and the Ash Can school. He favoured colourful street scenes of urban  middle-class life, heavily influenced by Impressionism. He was a prolific  draftsman, and his drawings (e.g.. Seated Woman, 1902) reveal an elegant  style not seen in his paintings. In 1912 he traveled to Europe to buy paint�  ings for the collection of Albert C. Barnes.

In the late Roman republic the audience called for death  with thumbs downward (or thumbs toward their breasts) and for mercy  with handkerchiefs (or thumbs downward, according to some sources).  The victor earned palm branches or money, and after a few victories a  gladiator could be freed. Most were slaves or criminals, but a talented or  handsome one could become a favourite of society; since they often  served as bodyguards, they occasionally became politically important.  Domitian delighted in using dwarfs and women as gladiators. With the  coming of Christianity the games began to fall into disfavour, but they  may have continued into the 6th century.

He entered Parliament in  1833 as a Tory, but after holding  various government posts, including  chancellor of the Exchequer (1852�</p><p>55, 1859-66), he slowly converted to  liberalism and became Liberal Party  leader in 1866. In his first term as  prime minister (1868-74), he over�  saw national education reform, vot�  ing reform (see Ballot Act), and the  disestablishment of the Irish Protes�  tant church (1869). In 1875-76 he  denounced the indifference of Ben�  jamin Disraeli�s government to the  Bulgarian Horrors. In his second  term, he secured passage of the  Reform Bill of 1884. His cabinet  authorized the occupation of Egypt  (1882), but his failure to rescue Gen.</p><p>Charles George Gordon in Khartoum  (1885) cost Gladstone much popularity and his government�s defeat. In  1886, throwing his weight behind support for Irish Home Rule, he was able  to regain control of Parliament, but when his Home Rule Bill was rejected  he resigned. He devoted the next six years to trying to convince the elec�  torate to grant Home Rule to Ireland. Liberals won a majority again in  1892, and in his fourth cabinet he piloted through another Home Rule  Bill, but it was soundly rejected by the House of Lords. He was buried  in Westminster Abbey.</p><p>Glama River See Glomma River</p><p>gland Collection of cells or tissue that removes specific substances from  the blood, alters or concentrates them, and then either releases them for  further use by the body or eliminates them.

It is made by cooling molten ingredients  fast enough so no visible crystals form. A poor conductor of heat and  electricity, glass takes on colours when certain metal oxides are included  in the mix. Most glass breaks easily. Obsidian is a naturally occurring  glass. Everyday glass (soda-lime or soda-lime-silica) is made of silica  (silicon dioxide), soda (sodium carbonate), and limestone (calcium car�  bonate), with magnesia (magnesium oxide) for sheet glass or alumina  (aluminum oxide) for bottle glass. Fused silica is an excellent glass but  expensive because of pure silica�s very high melting point. Borosilicate  glass (e.g., Pyrex) is used for cookware and laboratory glassware because  it expands very little when heated. Lead crystal is used for fine tableware.  It has a heavy feel because of its lead oxide content and a sparkle due to  its high refraction index. Even more specialized glasses include optical,  photosensitive, metallic, and fibre-optic.

Improvements by Octave Chanute (1832-1910) in 1896 and by Wilbur  and Orville Wright in 1902 perfected the control needed for developing  the Wrights� powered airplane in 1903. The slender-winged glider was  launched by being towed behind an airplane or a car. Gliders were used  in World War II to carry troops. Today they are mainly used for recre�  ation; the sailplane type is built for soaring on the lift from thermals.

He stud�  ied in Italy and Berlin, and in 1836 his first opera, A Life for the Tsar,  immediately earned him a reputation as Russia�s leading composer. Ele�  ments of Russian folk music were heard even more clearly in the opera  Ruslan and Ludmila (1842) and the orchestral work Kamarinskaya  (1848). The influence of these works on later Russian composers, includ�  ing Pyotr Ilyich Tchaikovsky and Nikolai Rimsky-Korsakov, was significant,  and Glinka is regarded as the father of the Russian national school.</p><p>Global Positioning System (GPS) Precise satellite-based naviga�  tion and location system originally developed for U.S. military use. GPS  is a fleet of more than 24 communications satellites that transmit signals  globally around the clock. With a GPS receiver, one can quickly and  accurately determine the latitude, the longitude, and in most cases the  altitude of a point on or above Earth�s surface. A single GPS receiver can  find its own position in seconds from GPS satellite signals to an accuracy  of one metre; accuracy within one centimetre can be achieved with sophis�  ticated military-specification receivers. This capability has reduced the  cost of acquiring spatial data for making maps while increasing carto�  graphic accuracy. Other applications include measuring the movement of  polar ice sheets or even finding the best automobile route between given  points.</p><p>global warming Increase in the global average surface temperature  resulting from enhancement of the greenhouse effect, primarily by air pol�  lution. In 2001 the UN Intergovernmental Panel on Climate Change esti�  mated that by 2100 global average surface temperatures would increase  2.5 to 10.4 �F (1.4 to 5.8 �C), depending on a range of scenarios for  greenhouse gas emissions. Many scientists predict that such an increase  would cause polar ice caps and mountain glaciers to melt rapidly, sig�  nificantly raising the levels of coastal waters, and would produce new  patterns and extremes of drought and rainfall, seriously disrupting food  production in certain regions. Other scientists maintain that such predic�  tions are overstated. The 1992 Earth Summit and the 1997 Kyoto Protocol  to the United Nations Framework Convention on Climate Change  attempted to address the issue of global warming, but in both cases the  efforts were hindered by conflicting national economic agendas and dis�  putes between developed and developing nations over the cost and con�  sequences of reducing emissions of greenhouse gases.</p><p>globalization Process by which the experience of everyday life,  marked by the diffusion of commodities and ideas, is becoming standard�  ized around the world. Factors that have contributed to globalization  include increasingly sophisticated communications and transportation  technologies and services, mass migration and the movement of peoples,  a level of economic activity that has outgrown national markets through  industrial combinations and commercial groupings that cross national  frontiers, and international agreements that reduce the cost of doing busi�  ness in foreign countries. Globalization offers huge potential profits to  companies and nations but has been complicated by widely differing  expectations, standards of living, cultures and values, and legal systems  as well as unexpected global cause-and-effect linkages.

About 150 have been identified in the Milky Way Galaxy. Most are  distributed in a spherical volume above and below the Galaxy�s disk (see  galactic halo). Globular clusters contain many more stars (10,000-  1,000,000) than open clusters do and can be several hundred light-years  in diameter. Because they are so distant from the solar system, most are  not visible to the unaided eye.

The county seat of Gloucestershire, it lies  on the River Severn and is linked by ship canal to docks in the Severn  estuary. It was founded as the Roman colony of Glevum in ad 96-98. An  abbey was founded there in 681; the town later became the capital of the  Anglo-Saxon kingdom of Mercia. Important economically even before the  Norman Conquest (1066), it was incorporated in 1483 and continued to  flourish as a trading centre. It has varied industries, including the manu�  facture of railway rolling stock and aircraft, and light and heavy engi�  neering works.</p><p>Gloucestershire Vglas-tor-.shirX Administrative (pop., 2001: 564,559),  geographic, and historic county, southwestern England. It is located at the  head of the River Severn estuary on the Welsh border; Gloucester is the  county seat. The Severn bisects the county from north to south. Prehis�  toric peoples were active in the area, as the numerous burial mounds indi�  cate; later, the Romans had military camps within the county, and  Gloucester was a Roman town of note. After the departure of the Romans,  the Saxons occupied the area. Throughout the Middle Ages Gloucester�  shire was a battlefield, reflected in the imposing Norman defensive castles  built on the Welsh frontier.

Linen  gloves were found in the tomb of Tut�  ankhamen in Egypt. Medieval Euro�  pean nobles wore both fabric and  leather gloves, often jeweled and  embroidered. By the 14th century  gloves were worn generally by  upper-class men; but in the 16th cen�  tury Catherine de Medicis, queen  consort of Henry li of France, made  gloves for women fashionable.  Glovemaking became an industry in  1834 when the glove-cutting die was  invented in France.

July 2, 1714, Erasbach, Upper Palatinate, Bavaria�d. Nov.  15, 1787, Vienna, Austria) German opera composer. Son of a forester, he  ran away to study music in Prague. He traveled widely, writing operas for  various cities, before settling in 1750 in Vienna, where he would remain�  except for an interlude in Paris (1773-79)�the rest of his life. In 1762,  with the librettist Ranieri di Calzabigi (1714-95), he wrote his famous  opera Orfeo eel Euridice, in which he borrowed aspects of French opera  to achieve a simplified dramatic style that decisively broke with the static  and calcified Italian style. His preface to Alceste (1767) laid out the  musico-dramatic principles of his �reform opera�; the goal was �simplic�  ity, truth and naturalness.� In 1773 he moved to Paris, where his former  pupil Marie-Antoinette was on the verge of becoming queen. There he won  acclaim for Iphigenie en Aulide (1774), Armide (1777), and Iphigenie en  Tauride (1779). His other operas (numbering more than 40 in all) include  Paride ed Elena (1770) and Echo et Narcisse (1779). He also wrote five  ballets, of which Don Juan (1761) was one of the first successful ballets  d�action.</p><p>glucose or dextrose or grape sugar or corn sugar Organic  compound, a simple sugar (monosaccharide), chemical formula C 6 H 12 0 6 .  The product of photosynthesis in plants, it is found in fruits and honey. As  the major circulating free sugar in blood, it is the source of energy in cell  function and a major participant in metabolism. Control of its level and  metabolism is of great importance (see insulin). Glucose and fructose make  up sucrose. Glucose units in long chains make up polysaccharides (e.g.,  cellulose, glycogen, starch). Glucose is used in foods, medicine, brewing,  and wine making and as the source of various other organic chemicals.</p><p>glue Adhesive substance resembling gelatin, extracted from animal tis�  sue, particularly hides and bones, or from fish, casein (milk protein), or  vegetables.

It is used in medicine and biochemical research and  as a feed additive.</p><p>gluten Mixture of proteins not readily soluble in water that occurs in  wheat and most other cereal grains. Its presence in flour makes produc�  tion of leavened baked goods (see baking) possible because the chainlike  gluten molecules form an elastic network that traps carbon dioxide gas and  expands with it. The properties of gluten vary with its composition, which  differs according to the source. Thus, doughs range from soft and exten�  sible to tough and elastic, depending on the gluten in the flours. Persons  with an allergy to gluten can often eat rice or spelt products.</p><p>glycerol Ygli-ss-.roA or glycerin Clear, colourless, viscous, sweet�  tasting liquid organic compound of the alcohol family, chemical formula  HOCH 2 CHOHCH 2 OH. With three hydroxyl (�OH) groups, it can form  three types of esters (monoglycerides, diglycerides, and triglycerides).  Mono- and diglycerides are common food additives. Fats and oils are  triglycerides; their processing into soap was the chief source of glycerol  until the mid-20th century, when industrial synthesis took over. Glycerol  has thousands of uses, including as an emulsifier, softening agent, plas�  ticizer, and stabilizer in baked goods, ice cream, and tobacco; in skin  lotions, mouthwashes, and cough medicines; as a protective medium for  freezing red blood cells, sperm, corneas, and other tissues; in printing inks  and in the gums and resins in paints and coatings; in antifreeze mixtures;  as a nutrient in fermentation; and as a raw material for nitroglycerin.</p><p>glyceryl trinitrate See nitroglycerin</p><p>glycine Ygll-.senV One of the nonessential amino acids. The simplest  amino acid (NH 2 CH 2 COOH), it occurs in many proteins; especially rich  sources are silk fibroin and gelatin.

Propylene glycol (1,2-  propanediol), much like ethylene glycol but not toxic, is used extensively  in foods, cosmetics, and oral hygiene products as a solvent, preservative,  and moisture-retaining agent. Other important glycols include 1,3-  butanediol and 1,4-butanediol, used as raw materials for plastics and other  chemicals; 2-ethyl-1,3-hexanediol, an insect repellent; and 2-methyl-2-  propyl-1,3-propanediol, the raw material of the tranquilizer meprobamate.</p><p>glycolysis \gli-'ka-b-s9s\ or glycolytic pathway or Embden-  Meyerhof-Parnas pathway \ , em-d3n- , mI-3r- l hof- , par-nos\  Sequence of 10 chemical reactions taking place in most cells that breaks  down glucose, releasing energy that is then captured and stored in ATP.  One molecule of glucose (plus coenzymes and inorganic phosphate) makes  two molecules of pyruvate (or pyruvic acid) and two molecules of ATP.  The pyruvate enters into the tricarboxylic acid cycle if enough oxygen is  present or is fermented into lactic acid or ethanol if not. Thus, glycolysis  produces both ATP for cellular energy requirements and building blocks  for synthesis of other cellular products.

The term, based  on the Greek gnosis (�secret knowledge�), was coined in the 17th cen�  tury, when it was applied liberally to ancient Christian heretical sects,  especially those described by their orthodox contemporaries as radically  dualistic and world-denying, and those who sought salvation through eso�  teric revelation and mystical spirituality. In the late 19th and the early  20th century, that view of Gnosticism was replaced with several group�  ings, and the discovery of the Nag Hammadi texts in 1945 greatly  enhanced the understanding of Gnosticism. The relationship with ancient  Christianity remains uncertain, but the Gospel of Thomas and the Gospel  of Mary (which portrays Mary Magdalene as a leading apostle) are gen�  erally seen as being grounded in Gnosticism. They emphasized the teach�  ings of Jesus, rather than his death and resurrection, as the key to salvation.  The teachings of Valentinus were the basis of the Gospel of Truth, a fusion  of Christian and Gnostic beliefs. Other texts previously considered Gnos�  tic are now assigned to distinct religious traditions, especially Hermeti-  cism (see Hermetic writings), Mandaeanism, and Manichaeism. The texts of  the Sethians have the best claim to the designation �Gnostic�; they  describe one supreme, good God and the creation, by a junior heavenly  being (Sophia), of an arrogant creature who then claims to be God. That  creature withholds from humanity moral knowledge and eternal life, but  Sophia plants the divine spirit within people to save them. Male and  female saviours (including Jesus) were sent from the world above to  instruct humanity in the knowledge of the true God and humanity�s own  divine nature. In general, Gnostics taught cosmological dualism, strict  asceticism, repudiation of material creation as evil, docetism, and the  existence of the divine spark in humans.</p><p>gnu Vnti\ or wildebeest Either of two species of African antelope  (genus Connochaetes).

Today  it exists only in national parks and  preserves. The brindled gnu, or blue  wildebeest, is reasonably abundant  over much of central and South  Africa. It is silvery gray with dark  vertical bands on the sides and has a  black mane, tail, and face, whitish  cheeks, and a tuft of dark hair on chin and throat. Both sexes of both  species have horns. Gnu live in often large, constantly moving herds and  graze on the grasses and scrub of open plains.</p><p>go Chinese weiqi or wei-ch'i Korean baduk Game that involves  two players alternately placing black and white stones on a board check�  ered by 19 vertical lines and 19 horizontal lines. The players attempt to  conquer territory by surrounding vacant areas or capture stones by sur�  rounding them. Points are awarded by conquering and capturing and  reduced by losing one�s stones. The game is also played in electronic for�  mats. Go probably originated in China, possibly as early as c. 2300 bc. It  was brought to Japan c. ad 500, where it developed into the modern game.

Sept. 19,  1339, Mount Yoshino, near Nara) Emperor of Japan whose efforts to  overthrow the Kamakura shogunate (see Kamakura period) resulted in a  split in the imperial family. When Go-Daigo came to the throne in 1318,  political authority was divided between the de jure government of the  emperor and the de facto government of the SHOGUN (military ruler) in  Kamakura. However, neither emperor nor shogun had real power, their  positions being controlled by powerful families. Go-Daigo sought to  regain and hold the reins of government himself; but he alienated Ash-  ikaga Takauji (see Ashikaga family), whose support had been crucial to his  victory, by neglecting to appoint him to the position of shogun. Takauji  rebelled and, victorious, elevated another member of the imperial family  to the throne. Go-Daigo fled south to the Yoshino Mountains and estab�  lished a rival court there. The period of Northern and Southern Courts  (nanboku cho) that followed lasted until 1392. See also Hojo family.</p><p>Goa \'go-o\ State (pop., 2001: 1,347,668), southwestern India.

It has an area of  1,429 sq mi (3,702 sq km), which includes the offshore island of Goa.  The capital is Panaji. Ruled by Hindu dynasties until 1472, it came under  the Portuguese in 1510. Their settlement of Old Goa became the capital  of Portuguese India. After India attained independence in 1947, it  demanded that Portugal cede Goa. Indian troops finally occupied Goa in  1961; it was incorporated into India in 1962 as part of the territory of  Goa, Daman, and Diu. It became a state in 1987. Goa is predominantly  agricultural; its distinctive architecture and fine beaches also make it a  popular tourist destination.</p><p>goat Any hollow-horned ruminant in the bovid genus Capra. Goats have  a lighter build and straighter hair than sheep; their horns arch backward;  and the tail is short. Males usually have a beard. Wild goats include the  ibex and markhor. Domesticated goats are descended from the pasang,  which is probably native to Asia. In China, Great Britain, Europe, and  North America, the domestic goat is primarily a milk producer; much of  the milk is used to make cheese.

It occupies an arc of land 1,000  mi (1,609 km) long and 300-600 mi (500-1,000 km) wide, with an esti�  mated area of 500,000 sq mi (1,300,000 sq km). Contrary to the image  often associated with a desert, much of the Gobi is not sandy but covered  with bare rock.</p><p>Gobind Singh \go- l bin-d3- , siq-g9, 'go-.bind-'siqN orig. Gobind Rai  (b. 1666, Patna, Bihar, India�d. Oct. 7, 1708, Nanded, Maharashtra) Sikh  Guru. The son of Guru Tegh Bahadur (1664-75), he was trained in the  martial arts in the Punjab. When he was nine his father was executed, and  he became the 10th and last Guru of Sikhism, presiding over the Sikh court  at Anandpur. A scholar and poet, he is credited with putting the Adi Granth  into its final form. His other great achievement was the founding (1699)  of the Khalsa, the egalitarian community that gave Sikhism its political  and religious definition and galvanized its martial energies. He was con�  tinually at war with local Hindu chiefs and the Mughal authorities, who  together forced the Sikhs out of Anandpur in 1704 and killed his four  sons. After the death of Aurangzeb, he supported the claim of the future  emperor, Bahadur Shah (1643-1712), to the throne. He was assassinated  before he could persuade Bahadur Shah to allow the Sikhs� return to  Anandpur.</p><p>Gobineau \g6-be-'no\, Joseph-Arthur, count de (b. July 14,  1816, Ville-d�Avray, France�d. Oct. 13, 1882, Turin, Italy) French dip�  lomat and writer. While serving in the diplomatic service (1849-77), he  wrote the Essay on the Inequality of Human Races (1853-55), which  asserted the superiority of the white race over others and labeled the  �Aryans,� or Germanic peoples, as the summit of civilization. He claimed  that white societies flourished as long as they remained free of �black and  yellow strains� and that dilution would lead to corruption. His theory of  racial determinism in Essay influenced the racist policies of such figures  as Robert F. Wagner, Houston Stewart Chamberlain, and Adolf Hitler.</p><p>goby Any of more than 800 species of carnivorous fishes (suborder  Gobioidei, order Perciformes), found worldwide but especially abundant  in the tropics. Most species are small bottom dwellers with a weak suction  cup formed by the fusion of their pelvic fins. About 700 species are typi�  cally elongated, sometimes scaleless fishes found along shores and among  reefs in tropical and temperate seas. They have two dorsal fins and a  rounded tail, lack a lateral line (sensory organ along the side of the body),  and are often brightly coloured. Most adults are no longer than 4 in.

Each of the major monotheistic world  religions worships a Supreme Being, who is the sole god of the universe,  the maker of all things, omniscient and all-powerful. God is also good.  In ancient Israel God was named Yahweh. The God of the Hebrew Bible  also became the God of Christianity, but generic words, such as theos in  Greek or Deus in Latin, were often used to refer to him. In Islam the term  is Allah. See also monotheism.</p><p>god and goddess Generic terms for the many deities of ancient and  modern polytheistic religions. There may be deities of earthly and celes�  tial phenomena as well as deities related to human values, pastimes, and  institutions, including love, marriage, hunting, war, and the arts. They may  be capable of being killed but are often immortal and always more pow�  erful than humans, though they are often described in human terms, with  all the flaws, thoughts, and emotions of humans.

He wrote film criticism for the influential journal Cahiers  du cinema before impressing audiences with his first feature film, the  improvisatory and original Breathless (1960), which established him as  the apostle of the New Wave. He continued to explore new techniques in  films such as My Life to Live (1962), Pierrot le fou (1965), Alphaville  (1965), and Weekend (1968), using the camera creatively to express politi�  cal commentary. He returned to themes of more universal concern with  Every Man for Himself (1979) and Passion (1982) but stirred controversy  with his updated nativity story in Hail Mary! (1985). He received wide  critical acclaim for Histoire(s) du Cinema (1997), a video study of French  film, and In Praise of Love (2001).</p><p>Godavari River \go-'da-vo-re\ River, central India.

It crosses Andhra Pradesh state, and turns southeast  for its last 200 mi (320 km) before reaching the Bay of Bengal. Its total  length is about 910 mi (1,465 km). The development of an irrigation-canal  system, linking its delta with that of the Krishna River to the southwest, has  made the land one of the richest rice-growing areas of India. The Godavari,  throughout its entire length, is sacred to the Hindus.</p><p>Goddard family New England cabinetmakers. Of English ancestry,  the Goddards intermarried with the Townsend family, equally famous cabi�  netmakers. John Goddard (1723-1785), the son of a carpenter, moved in  the 1720s from Massachusetts to Newport, R.I., where he and his brother  worked for Job Townsend. By the 1760s Goddard had established his own  workshop and become Newport�s leading cabinetmaker, producing simple  adaptations in the Queen Anne style. He originated the blockfront, a dis�  tinctive front for desks, secretaries, and cabinets, decorated with his char�  acteristic carved shell ornaments; pieces were made of mahogany from  the West Indies and South America. Some 20 Goddard and Townsend  craftsmen of four generations are known. Goddard-Townsend furniture  was among the finest made in North America in the 18th century.</p><p>Goddard, Robert Hutchings (b.

In laboratory work  there, he proved that thrust and consequent propulsion can take place in</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Godden &#x25BA; Goebbels I 773</p><p>a vacuum and was the first to develop a ROCKET engine using liquid pro�  pellants (static tested in 1925). In 1926 Goddard successfully launched  the world�s first liquid-fueled rocket (gasoline and liquid oxygen) from a  farm in Massachusetts. In 1935, having relocated his testing site to New  Mexico, he was the first to send a liquid-fueled rocket faster than the speed  of sound. He patented the first practical automatic steering apparatus for  rockets, developed staged rockets designed to gain great altitudes, and  developed the first rocket-fuel pumps, self-cooling rocket engines, and  other components of a propulsion system designed for space exploration.  Much of his work anticipated that of Wernher von Braun in Germany but  was ignored by the U.S. government until after his death at the end of  World War II.</p><p>Godden, Rumer in full Margaret Rumer Godden Haynes-  Dixon (b.

Her novel Black  Narcissus (1939; film, 1947) brought her popular success. The story of a  group of English nuns in the Himalayas, it deals with her recurring themes  of cultural conflicts and obsessive love. She often wrote about children, as  in The River (1946; filmed by Jean Renoir in 1951) and The Greengage  Summer (1958; film, 1961), and wrote almost two dozen books for chil�  dren.</p><p>Godel Vgoe-d3l,\ English \ , go(r)-d9l\ / Kurt (b.

He began his career on the faculty of the  University of Vienna, where he produced his groundbreaking proof (see  Godel's theorem) in the early 1930s. He emigrated to the U.S. in 1940 and  taught at the Institute for Advanced Study at Princeton. There his close  friendship with Albert Einstein led him into the field of general relativity  theory and to solutions of some of Einstein�s equations. A quiet and unas�  suming man, Godel did not at first recognize the importance of his famous  theorem, and later in life he declined many of the honours that it brought  him.</p><p>Godel's theorem Principle of the foundations of mathematics. One of  the most important discoveries of 20th-century mathematics, it states the  impossibility of defining a complete system of axioms that is also consis�  tent (does not give rise to contradictions). Any formal system (e.g., a  computer program or a set of mathematical rules and axioms) powerful  enough to generate meaningful statements can generate statements that  are true but that cannot be proven or derived within the system. As a con�  sequence, mathematics cannot be placed on an entirely rigorous basis.  Named for Kurt Godel, who published his proof in 1931, it immediately  had consequences for philosophy (particularly logic) and other areas. Its  ramifications continue to be debated.</p><p>Godey's Lady's Book \'go-dez\ Monthly magazine for women, one  of the most successful and influential periodicals in 19th-century America.

His relaxed manner and affable banter as a radio host won him such a  wide following that he had two daily shows and a weekly show on CBS  in the 1940s. His variety show, which transferred to television as Arthur  Godfrey�s Talent Scouts and later The Arthur Godfrey Show (1948-60),  launched the careers of numerous popular entertainers.</p><p>Godfrey of Bouillon \bii-'yo n \ (b. c. 1060�d.

About 1160 Godfrey entered the mon�  astery of Saint-Victor in Paris. He left after 20 years for a rural priory,  where he wrote his principal work, Microcosmus, an attempt to system�  atize history and knowledge into a rational structure. Recalling Classical</p><p>philosophy and that of the early Church Fathers, it asserts that mankind  is a microcosm containing the material and spiritual elements of reality.  In his other notable work, The Fount of Philosophy (c. 1176), he pro�  posed a classification of learning. His writings are considered prime  examples of 12th-century humanism.</p><p>godi \'go-de\ In pre-Christian Scandinavia, a priest-chieftain.

She  was the wife of Leofric, earl of Mercia (d. 1057), with whom she founded  a monastery at Coventry. There is no evidence connecting the rider with  the historical Godiva. According to the legend, Leofric, exasperated over  Godiva�s ceaseless imploring that he reduce Coventry�s heavy taxes,  declared he would do so if she rode naked through the crowded market�  place. She did so, her long hair covering all of her body except her legs;  as a result Leofric removed all tolls except those on horses. A later  chronicle asserts that Godiva required the townsmen to remain indoors at  the time fixed for her ride. Peeping Tom, a citizen who looked out his  window, became part of the legend in the 17th century, and in most  accounts he was struck blind or dead.</p><p>Godoy \gd-'d6i\, Manuel de (b.

On Charles�s accession (1788) Godoy continued as a  royal favourite and was made duke de Alcudia and prime minister (1792-  98, 1801-08). In 1795 Godoy negotiated a favourable peace after Spain�s  defeat by France and was awarded the title Prince of the Peace. He allied  Spain with France against England, which brought a Spanish naval defeat  at Cape St. Vincent (1797) and the disastrous defeat at the Battle of Tra�  falgar. In 1808, when it was learned that Napoleon planned to seize parts  of Spain in the Peninsular Wars, the Spanish court tried to flee.

After serving in  the court of Ivan IV, he was named guardian to Ivan�s dim-witted son Fyo�  dor I and became the virtual ruler of Russia as Fyodor�s chief adviser from  1584. When Fyodor�s little brother Dmitry died mysteriously in 1591,  Godunov was suspected of having had him put to death. When Fyodor  died without heirs in 1598, an assembly of clergy and gentry elected  Godunov tsar. A capable ruler, he instituted many reforms, but continu�  ing boyar opposition and a general famine (1601-03) eroded his popular�  ity. The False Dmitry led an army into Russia, and on Boris�s sudden death,  resistance broke down, and the country lapsed into the Time of Troubles.</p><p>Godwin, William (b.

A gifted speaker, Goebbels also  edited the party�s journal and began to create the Fiihrer myth around Hit�  ler, instituting the party demonstrations that helped convert the masses to  Nazism. After Hitler seized power in 1933, Goebbels took control of the  national propaganda machinery. During World War II he carried on a per�  sonal propaganda blitz to raise hopes on the home front. Named chancellor  in Hitler�s will, he remained with Hitler to the end.

A member of the rightist German National People's Party, he  had to resign as mayor of Leipzig when his relations with the Nazi Party  deteriorated. He collaborated with conservative generals led by Ludwig  Beck against Hitler, after whose overthrow Goerdeler was to become chan�  cellor.

Nothing is known of his life before 1467, when  he became a master in the painters� guild in Ghent. He received numer�  ous commissions from the town of Ghent (processional banners, heraldic  shields, etc.) through 1475. He was elected dean of the guild in 1474. The  next year, at the height of his career, he entered a monastery near Brus�  sels as a lay brother, though he continued to paint and travel. A mental  breakdown in 1481 led to a suicide attempt, and he died the following  year. His masterpiece and only documented work is a large triptych known  as the Portinari Altarpiece (c. 1473-78); an outstanding early example of  northern realism, it shows psychological insight and an emotional inten�  sity unprecedented in Flemish art. A poignant and disturbing Death of the  Virgin is also attributed to him.</p><p>Goethals Vgo-tholzV George Washington (b. June 29, 1858,  Brooklyn, N.Y., U.S.�d. Jan. 21,1928, New York, N.Y.) U.S. army officer  and engineer. After graduating from West Point, he served in the U.S. Army  Corps of Engineers, where he gained experience in the construction of  canals and harbours; he also taught engineering at West Point. Appointed  by Pres. Theodore Roosevelt to direct the building of the Panama Canal, he  successfully confronted complex problems of both engineering and logis�  tics. He was appointed the Canal Zone�s first governor (1914-17). In World  War I, he directed procurement for and the movement of U.S. troops at  home and abroad. After retiring in 1919, he served as a consultant to many  organizations, including the Port of New York Authority.</p><p>Goethe Ygce-te,\ English Vg9(r)-t3\, Johann Wolfgang von (b.  Aug. 28, 1749, Frankfurt am Main�d. March 22, 1832, Weimar, Saxe-  Weimar) German poet, novelist, playwright, and natural philosopher. In  1773 Goethe provided the Sturm und Drang movement with its first major  drama, Gotz von Berlichingen, and in 1774 with its first novel, The Sorrows  of Young Werther, an extraordinarily popular work in its time, in which he  created the prototype of the Romantic hero. In 1775 he accepted an  appointment at the ducal court at Weimar, where he would remain the rest  of his life; his presence would establish Weimar as a literary and intellec�  tual centre. His poetry includes lyrics in praise of natural beauty and ballads  such as �The Elf King� (1782) that echo folk themes. Many early works  were inspired by a series of passionate loves. Contact with classical Greek  and Romantic culture during an Italian sojourn helped shape his plays,  including Iphigenie aufTauris (1787), Egmont (1788), and Torquato Tasso  (1790), and the poems in Roman Elegies (1795). From 1794, Friedrich  Schiller became his most important and influential friend. Wilhelm Meis-  ter�s Apprenticeship (1795-96) is often called the first bildungsroman; it  was followed many years later by Wilhelm Meister�s Travels (1821-29).  His chief masterpiece, the philosophical drama Faust (Part I, 1808; Part II,  1832), concerns the struggle of the soul for knowledge, power, happiness,  and salvation. Goethe also wrote extensively, if idiosyncratically, on  botany, optics, and other scientific topics. In his late years he was cel�  ebrated as a sage and visited by world luminaries. The greatest figure of  German Romanticism, he is regarded as a giant of world literature.</p><p>goethite Vgor-.tlt, 'g6-,thlt\ Widespread iron hydroxide mineral,  a-FeO(OH), the most common ingredient of iron rust.

Goethite varies in colour from yellow-brown to red and is the  source for the pigment known as yellow ocher; it is also the primary min�  eral in some important iron ores, such as those in the Alsace-Lorraine  basin in France. Other important deposits are found in the southern Appa�  lachian Mountains of the U.S., and in Brazil, South Africa, Russia, and  Australia.</p><p>Goff man, Erving (b.

He  studied primarily face-to-face communication and related rituals of social  interaction; his The Presentation of Self in Everyday Life (1959) laid out  the dramaturgical perspective he used in subsequent studies, such as Asy�  lums (1961) and Stigma (1964). In Frame Analysis (1979) and Forms of  Talk (1981), he focused on the ways people �frame� or define social real�  ity in the communicative process.

At 16 he was apprenticed to art dealers in The  Hague, and he worked in their London and Paris branches (1873-76).  After brief attempts at missionary work and theology, he studied draw�  ing at the Brussels Academy; late in 1881 he settled at The Hague to work  with a Dutch landscape painter, Anton Mauve. During his early years he  painted three types of subjects�still life, landscape, and figure�all inter�  related by their reference to the daily life of peasants (e.g.. The Potato  Eaters, 1885). After briefly studying at the Antwerp Academy, in 1886 he  left to join his brother Theo, an art dealer, in Paris. There he met Henri de  Toulouse-Lautrec, Paul Gauguin, and others involved in Impressionism and  Post-Impressionism. By the summer of 1887 he was painting in pure colours  and using broken brushwork that was at times pointillistic, and by the  beginning of 1888 his Post-Impressionist style had crystallized. He left  Paris in February 1888 for Arles, in southeastern France. The pictures he  created over the following 12 months�depicting blossoming fruit trees,  views of the town and surroundings, self-portraits, portraits of Roulin the  postman and other friends, interiors and exteriors of the house, sunflow�  ers, and landscapes�marked his first great period. Gauguin arrived in  October 1888, and for two months he and van Gogh worked together;  but, while each influenced the other to some extent, their relations rap�  idly deteriorated. On Christmas Eve 1888, physically and emotionally  exhausted, van Gogh snapped under the strain; after arguing with  Gauguin, he cut off the lower half of his own left ear. At the end of April  1889, van Gogh entered an asylum but continued to paint; during his  12-month stay he completed 150 paintings and drawings. A move to  Auvers-sur-Oise in 1890 was followed by another burst of activity, but  he soon suffered a relapse and died that July of a self-inflicted gunshot  wound. His 10-year artistic career produced more than 800 paintings and  700 drawings, of which he sold only one in his lifetime. His work had a  powerful influence on the development of modern painting, and he is  considered the greatest Dutch painter since Rembrandt.</p><p>Gogol Vgo-.goH, Nikolay (Vasilyevich) (b. March 19, 1809,  Sorochintsy, near Poltava, Ukraine, Russian Empire�d. Feb. 21, 1852,  Moscow, Russia) Russian writer. Gogol tried acting and worked at minor  government jobs in St. Petersburg before achieving literary success with  Evenings on a Farm near Dikanka (1831-32). His pessimism emerged in  such stories as �Taras Bulba� (1835) and �Diary of a Madman� (1835).  His farcical drama The Government Inspector (1836) lampooned a cor�  rupt government bureaucracy. From 1836 to 1846 he lived in Italy. Dur�  ing this time he laid the foundations of 19th-century Russian realism with  his masterpiece, the novel Dead Souls (1842), a satire about serfdom and  bureaucratic inequities in which he hoped to castigate abuses and guide  his countrymen through laughter, and his story �The Overcoat� (1842).  His collected stories (1842) received great acclaim. Soon afterward he  came under the influence of a fanatical priest who prompted him to burn  the manuscript of the second volume of Dead Souls. He died a few days  later at age 42, perhaps of intentional starvation, on the verge of madness.</p><p>Gogra River See Ghaghara River</p><p>Goibniu Vg6v y -n y ii\ Ancient Celtic blacksmith god.

The thyroid can grow to 50 times its normal weight, inter�  fere with breathing and swallowing, and cause a choking feeling. Simple  (endemic) goitre, the most common, is due to low iodine intake. It and  related conditions result from various defects in thyroid hormone synthe�  sis (hypothyroidism). Advanced cases are treated with thyroid hormone  or surgical removal of the thyroid if it obstructs breathing. The cause of  sporadic goitre, which occurs in areas where iodine intake is more than  adequate, remains a mystery.

Historically, Golconda was famous for its diamonds, mined in the  nearby hills.</p><p>gold Metallic chemical element, one of the transition elements, chemical  symbol Au, atomic number 79. It is a dense, lustrous, yellow, malleable  precious metal, so durable that it is virtually indestructible, often found  uncombined in nature. Jewelry and other decorative objects have been  crafted from gold for thousands of years. It has been used for coins, to  back paper currencies, and as a reserve asset. Gold is widely distributed  in all igneous rocks, usually pure but in low concentrations; its recovery  from ores and deposits has been a major preoccupation since ancient times  (see cyanide process). The world�s gold supply has seen three great leaps,  with Christopher Columbus�s arrival in the Americas in 1492, with discov�  eries in California (see gold rush) and Australia (1850-75), and discov�  eries in Alaska, Yukon (see Klondike), and South Africa (1890-1915). Pure  gold is too soft for prolonged handling; it is usually used in alloys with  silver, copper, and other metals. In addition to being used in jewelry and  as currency, gold is used in electrical contacts and circuits, as a reflective  layer in space applications and on building windows, and in filling and  replacing teeth. Dental alloys are about 75% gold, 10% silver. In jewelry,  its purity is expressed in 24ths, or karats: 24-karat is pure, 12-karat is  50% gold, etc. Its compounds, in which it has valence 1 or 3, are used  mainly in plating and other decorative processes; a soluble chloride com�  pound has been used to treat rheumatoid arthritis.</p><p>Gold Coast Section of the coast of the Gulf of Guinea, western Africa.  Extending approximately from Axim, Ghana, in the west to the Volta River  in the east, it was so called because it was an important source of gold.  It was an area of intense colonial rivalry from the 17th century. Acquired  as a colony by the British in the 19th century and named the Gold Coast,  the area achieved independence as the Republic of Ghana in 1957.</p><p>Gold Coast See Ghana</p><p>gold reserve Fund of gold bullion or coin held by a government or  bank. In the past, banks accumulated gold reserves to fulfill their prom�  ise to pay their depositors in gold. Commercial banks received deposits  subject to repayment in gold on demand and issued notes redeemable in  gold on demand. Most gold reserves eventually shifted to central banks,  which took over the function of issuing paper money. Gold reserves were  moved again in the 1930s, when many governments required their cen�  tral banks to turn over to the national treasuries all or most of their gold  holdings. In the U.S., the Gold Reserve Act of 1934 required Federal  Reserve banks to turn over all gold bullion or coin to the U.S. Treasury,  which placed most of the reserves at Fort Knox.</p><p>gold rush Rapid influx of fortune seekers to the site of newly discov�  ered gold deposits. In North America, the first major gold strike occurred  in California in 1848, when John Marshall, a carpenter building a saw�  mill for John Sutter, found gold. Within a year about 80,000 �forty-niners�  (as the fortune seekers of 1849 were called) had flocked to the California</p><p>gold fields, and 250,000 had arrived by 1853. Some mining camps grew  into permanent settlements, and the demand for food, housing, and sup�  plies propelled the new state�s economy. As gold became more difficult  to extract, companies and mechanical mining methods replaced individual  prospectors. Smaller gold rushes occurred throughout the second half of  the 19th century in Colorado, Nevada, Idaho, Montana, South Dakota,  Arizona, and Alaska, resulting in the rapid settlement of many areas;  where gold veins proved small, the settlements later became ghost towns.  Major gold rushes also occurred in Australia (1851), South Africa (1886),  and Canada (1896). See also Klondike gold rush.</p><p>gold standard Monetary system in which the standard unit of cur�  rency is a fixed quantity of gold or is freely convertible into gold at a  fixed price. The gold standard was first adopted in Britain in 1821. Ger�  many, France, and the U.S. instituted it in the 1870s, prompted by North  American gold strikes that increased the supply of gold. The gold stan�  dard ended with the outbreak of World War I in 1914; it was reestablished  in 1928, but because of the relative scarcity of gold, most nations adopted  a gold-exchange standard, supplementing their gold reserves with curren�  cies (U.S. dollars and British pounds) convertible into gold at a stable rate  of exchange. Though the gold-exchange standard collapsed during the  Great Depression, the U.S. set a minimum dollar price for gold, an action  that allowed for the restoration of an international gold standard after  World War II. In 1971 dwindling gold reserves and an unfavourable bal�  ance of payments led the U.S. to suspend the free convertibility of dollars  into gold, and the gold standard was abandoned.

After passing the Illinois bar  examination at the age of 20, he practiced law in Chicago from 1929 to  1948. He first gained national attention as counsel for the Chicago News�  paper Guild during its 1938 strike. In 1948 he went to Washington, D.C., as  general counsel for the Congress of Industrial Organizations (CIO) and the  United Steelworkers of America. He was instrumental in merging the  American Federation of Labor (AFL) and the CIO in 1955. After serving as  U.S. secretary of labour (1961-62), he was appointed to the Supreme Court  of the United States (1962-65). At the request of Pres. Lyndon B. Johnson, he  gave up his seat on the court to become U.S. ambassador to the UN (1965�  68), a post he resigned in protest over Johnson�s escalation of the Vietnam  War. He twice served as ambassador-at-large for Pres. Jimmy Carter.</p><p>Golden Bull of 1356 Constitution for the Holy Roman Empire promul�  gated by Charles IV.

Founded by Guru Ramdas (1574-81) and completed by Guru Arjan Dev  in 1604, the temple has entrances on four sides, signifying a welcome to  all creeds and castes. Though destroyed in the 1760s by Afghan invad�  ers, it was rebuilt, and in the early 19th century it acquired its marble  walls and gold-plated copper domes. The surrounding buildings include  a meeting hall, reference library, and museum, as well as the shrine known  as the Akal Takhat. In 1984 the complex was seriously damaged during  a confrontation between Sikh separatists and government troops; it was  subsequently restored.</p><p>goldeneye or whistler Either of two species of small, yellow-eyed  diving ducks that produce a whistling sound with their rapidly beating  wings. The common goldeneye ( Bucephala clangula) breeds throughout  the Northern Hemisphere; Barrow�s goldeneye ( B. islandica) breeds pri�  marily in northwestern North America and Iceland. Both winter mainly  in northern coastal waters. Both are about 18 in. (46 cm) long and have  a black back marked with white, white sides and breast, and conspicuous  white patches in front of the eyes. The head of the common is dark green;  that of the Barrow�s is purplish black. Both nest in tree cavities and pre�  fer a diet of aquatic invertebrates. They are prized as game birds.</p><p>golden rod Any of the approximately 100 species of weedy, usually  perennial herbaceous plants that make up the genus Solidago, in the COM�  POSITE family. Most are native to North America; a few grow in Europe and  Asia. They have toothed leaves and clustered yellow flower heads com�  posed of both disk and ray flowers. Characteristic plants in eastern North  America, they are found almost everywhere�in woodlands, swamps, on  mountains, in fields, and along roadsides�and are a prominent feature of  autumn from the Great Plains east to the Atlantic.

His first  and best-known novel was Lord of the Flies (1954; film, 1963, 1990),  about a group of boys isolated on an island who revert to savagery. Later  works, several of which are likewise parables of the human condition that  show the thinness of the veneer of civilization, include The Inheritors  (1955), Fincher Martin (1956), The Spire (1964), Rites of Passage (1980,  Booker Prize), and Close Quarters (1987).

She immi�  grated to the U.S. in 1885, settling in Rochester, N.Y. Moving to New York  City in 1889, she formed a close association with the Russian anarchist  Alexander Berkman (1870-1936); the two corresponded regularly during  Berkman�s imprisonment (1892-1906) for an assassination attempt on  Henry Clay Frick. In 1893 Goldman herself was jailed for inciting a riot  when a group of unemployed workers reacted to a fiery speech she had  delivered. She founded and edited (1906-17) the anarchist magazine  Mother Earth and wrote on anarchism, feminism, birth control, and other  social problems. After Berkman�s release she continued anarchist activities  with him until 1917, when they were arrested for agitating against the mili�  tary draft. Upon her release in 1919, she and other anarchists were deported  to the Soviet Union. She moved to England in 1921 and later to Canada and  Spain, continuing to lecture throughout Europe.</p><p>Goldmark, Peter Carl (b. Dec. 2, 1906, Budapest, Hung.�d.

In 1948 he introduced the long-playing (LP)  phonograph record, which revolutionized the recording industry. In 1950  he developed the scanning system that would allow the U.S. Lunar Orbiter  spacecraft (launched in 1966) to relay photographs 238,000 mi (380,000  km) from the Moon to Earth.</p><p>Goldoni, Carlo (b. Feb. 25, 1707, Venice�d. Feb. 6, 1793, Paris,  France) Italian playwright. He practiced law but preferred to write plays,  beginning with Belisario (1734). He renovated the commedia dell'arte form  by replacing its masked stock figures with realistic characters, its repeti�  tive action with tightly constructed plots, and its predictable farce with  spontaneity in plays such as Pamela (1750), based on Samuel Richardson�s  novel. His comedy of manners La locandiera (1753) is still performed (as  Mine Hostess). When rivals ridiculed his innovations, he took his realis�  tic comedy to Paris, where he directed the Comedie-Italienne and wrote  many plays in French. He later rewrote them for Italian audiences, and  The Fan (1763) became one of his greatest successes.</p><p>Goldschmidt, Victor Moritz (b. Jan. 27, 1888, Zurich, Switz.�d.  March 20, 1947, Oslo, Nor.) Swiss-born Norwegian mineralogist and  petrologist. He became director of the Mineralogical Institute of the Uni�  versity of Kristiania (now Oslo) in 1914. The dearth of raw materials dur�  ing World War I led Goldschmidt to research in geochemistry. His work  in that area, and more general studies after the war, marks the beginnings  of modern geochemistry. His Geochemical Laws of the Distribution of  the Elements (8 vol., 1923�38) laid the foundations of inorganic crystal  chemistry. During the 1930s he studied the relative cosmic abundance of  the elements. In 1942 he escaped a Nazi concentration camp and fled to  England; after the war he returned to Oslo.</p><p>Goldsmith, Oliver (b. Nov. 10, 1730, Kilkenny West, County West�  meath, Ire.�d.

Settling in  London, he began writing essays,  some of which were collected in The  Citizen of the World (1762). In 1764  he became an original member of  Samuel Johnson�s famous Club. He  won a reputation as a poet with The  Traveller (1764), confirmed by his  famous pastoral elegy The Deserted  Village (1770). The Vicar of Wake�  field (1766) revealed his skill as a  novelist. The charming farce She  Stoops to Conquer (1773) was his  most effective play.

A Republican, he was elected  to the U.S. Senate in 1952, and he quickly established himself as a strong  conservative, calling for a harsh diplomatic stance toward the Soviet  Union, opposing arms-control negotiations with that country, and accus�  ing the Democrats of creating a quasi-socialist state at home. In 1964 he  won the Republican nomination for president but lost the election to  Democratic Pres. Lyndon B. Johnson largely because of popular fears that  Goldwater would provoke a nuclear war with the Soviets. Returning to  the Senate (1969-87), he helped persuade Richard Nixon to resign in 1974.

By the time  that company merged into MGM (1924), he had become an independent  producer. He employed top screenwriters, directors, and actors to produce  films of high quality, including Wuthering Heights (1939), The Little  Foxes (1941), The Best Years of Our Lives (1946), Guys and Dolls (1955),  and Porgy and Bess (1959).</p><p>golem \'go-tam\ In Jewish folklore,  the Middle Ages stories were told of  wise men who could bring clay effi�  gies to life by means of magic  charms or sacred words.

Later golems were  imagined as protectors of the Jews in  times of persecution, but also had a  frightening aspect.</p><p>golf Game in which a player using  special clubs attempts to sink a small  ball with as few strokes as possible  into each of the 9 or 18 successive  holes on an outdoor course. A hole  includes (1) a teeing area, a clearing  from which the ball is initially driven  toward the actual hole, or cup; (2) a fairway, a long, closely mowed, and  often angled lane; (3) a putting green, a smooth grassy area containing  the hole; and (4) often one or more natural or artificial hazards (such as  bunkers). Each hole has associated with it a par, or score standard, usu�  ally from par 3 to par 5. The origins of the game are difficult to ascer�  tain, although evidence now suggests that early forms of golf were played  in the Netherlands first and then in Scotland. Golf developed in  Scotland�the courses were originally fields of grass that sheep had  clipped short in their characteristic grazing style. Golf balls were origi�  nally made of wood; wood was replaced in the 17th century by boiled  feathers stuffed in a leather cover, in the 19th century by gutta-percha,  and in the 20th century by hard rubber. Clubs, limited in number to 14,  are known by the traditional names of �irons� (primarily for mid-range  to short shots) and �woods� (primarily for longer shots); today irons are  more likely made of stainless steel, and the heads of woods are usually  made of metal such as steel or titanium.</p><p>an image that comes to life.

In 1727 he became a member of the  Supreme Privy Council, which governed for Peter II until his death (1730).  He urged the council to offer the throne to Anna Ivanovna if she would  sign a set of conditions transferring crucial prerogatives to the council.  She initially agreed, then dissolved the council.

Leader of the Polish Communist Party (1956-70). In 1926 he joined the  underground Communist Party and became a union organizer. In World  War II he was active in the communist underground in Warsaw. After the  Soviet liberation of Poland, he ascended through the party ranks quickly.  Though ruthless in eliminating opposition to communist rule, he publicly  opposed some Soviet policies and was accused of �nationalist deviation�  by Joseph Stalin in 1948 and arrested in 1951. He was rehabilitated in 1956  and elected party first secretary. At first universally supported, he adopted  halfhearted reforms that were ultimately disappointing. In 1970 he was  ousted along with other top leaders following workers� riots over food  prices.</p><p>Goncalves \g6 n n-'sal-vish\, Nuno (fl. 1450-72) Portuguese painter.  He is recorded as court painter to Alfonso V in 1450, but his works for  the Portuguese court have not survived. His altarpiece for Lisbon Cathe�  dral was destroyed in the great earthquake of 1755. His six-paneled St.  Vincent altarpiece (c. 1460-70), discovered only in 1882, is the outstand�  ing Portuguese painting of the 15 th century, a remarkable portrait gallery  of scrupulously realistic, stiffly posed figures, with affinities to Italian and  Flemish art.</p><p>Goncalves Dias \go n n- , sal-vish- , de-ash\ / Antonio (b. Aug. 10, 1823,  Boa Vista, near Caxias, Maranhao, Braz.�d. Nov. 3, 1864, off the coast  of Maranhao) Brazilian poet. A respected ethnologist and scholar, he lived  much of the time abroad. He drowned at age 41. His songs, collected in  First Poems (1847), More Poems (1848), and Last Poems (1851), which  display both exuberance and longing, are a celebration of the New World  as a tropical paradise. His �Song of Exile� (1843) is known to every Bra�  zilian schoolchild, and he is regarded as the national poet of Brazil.</p><p>Goncourt \go n -'kur\, Edmond (-Louis-Antoine Huot de) and  Jules (-Alfred Huot de) (respectively b.

The Goncourt brothers were enabled  by a legacy to devote their lives largely to writing. They produced a series  of social histories (from 1854) as well as a body of art criticism. The most  lasting of their meticulously detailed naturalistic novels is Germinie Lac-  erteux (1864), which explores working-class life. Their published jour�  nals (kept 1851-96) represent both a revealing autobiography and a  monumental history of social and literary life in 19th-century Paris. By  his will Edmond established the Academie Goncourt, which annually  awards the Prix Goncourt, one of France�s preeminent literary prizes, to  the author of an outstanding work of French literature.</p><p>Gondwana or Gondwana land Hypothetical former superconti�  nent in the Southern Hemisphere, which included modern South America,  Africa, southern Europe, India, Australia, and much of the Middle East and  Antarctica.

Very influential in  his era, he developed the difficult, complex poetic style that became  known as gongorismo\ it provoked scorn and enmity from many of his  contemporaries and was so exaggerated by less gifted imitators that his  reputation suffered until the 20th century, when his poems began to be  appreciated for their cold beauty. Solitudes (1613) is perhaps his most out�  standing work in the style. His lighter poetry� romances (folk ballads),  letrillas (short lyric poems), and sonnets�achieved greater popular suc�  cess.</p><p>Gonne, Maud (Edith) married name Maud MacBride (b. Dec.  21, 1866, Tongham, Surrey, Eng.�d. April 27, 1953, Dublin, Ire.) Irish  activist, actress, and feminist. Gonne became involved in the Irish nation�  alist movement at an early age and cofounded the Daughters of Erin  (1900-14; a nationalist organization). She was also a founder of Sinn Fein.  While engaged in political activities, Gonne became a noted actress. The  poet and dramatist W.B. Yeats fell in love with her, and she was the model  for the heroine of his play Cathleen ni Houlihan (1892). Nevertheless,  Gonne turned down his many proposals of marriage and in 1903 married  Maj. John MacBride, a fellow activist who was executed for his role in  the Easter Rising in 1916. Their son, SeAn MacBride, the first chairman of  Amnesty International, won the Nobel Prize for Peace in 1974.</p><p>gonorrhea \,ga-n3-'re-3\ Sexually transmitted disease. It is characterized  by genitourinary inflammation, caused by the bacterium Neisseria gonor-  rhoeae (gonococcus). Symptoms in men include burning on urination, dis�  charge of pus, and, with deeper infection, frequent urination, sometimes  with blood. Women may have mild vaginal discharge and burning, but  there is usually no sign until a sex partner is infected or complications�  sometimes serious�arise from its spread beyond the cervix. If spontane�  ous recovery does not occur, it may cause sterility in both sexes but is rarely  fatal. Gonorrhea is common worldwide. Penicillin, generally a successful  treatment, reduced its incidence, but resistant strains are increasingly  found. Many cases are not reported. Penicillin may also mask coexisting  syphilis (since the dose to cure gonorrhea does not cure syphilis).</p><p>Gonzaga dynasty \gon-�dza-ga\ Italian dynasty that ruled Mantua  1328-1707 and Montferrat and Casale 1536-1707. Its history began with  Luigi I (or Lodovico; 1267-1360), who gained control of Mantua in 1328.  Its rulers, many noted as military and political leaders and patrons of the  arts, included Giovan Francesco II (died 1444), a general and founder of  the first school based on humanistic principles (1423); and Federigo II  (died 1540), captain general of the papal forces who was made duke of  Mantua in 1530. Mantua was annexed by Austria in 1708.</p><p>Good Feelings, Era of (1815-25) Period of U.S. national unity and  complacency. A Boston newspaper coined the term in 1817 to describe a  nation free from the influence of European political and military events.  The good feelings were stimulated by two events of 1816, during James  Madison�s presidency: enactment of the first U.S. protective tariff, and  establishment of the second national bank. The presidency of James Mon�  roe (1817-25) was marked by the dominance of the Democratic-  Republican Party and the decline of the Federalist Party.</p><p>Good Friday Friday before Easter, commemorating the crucifixion of  Jesus. As early as the 2nd century it was kept by Christians as a day of  penance and fasting. The Eastern Orthodox and Roman Catholic churches  have special liturgies for the day, which include readings and prayers  commemorating Christ�s sufferings on the cross. Protestant churches also  hold special services on Good Friday.</p><p>Good Hope, Cape of Rocky promontory, southwestern coast, West�  ern Cape province, South Africa. It was sighted by the Portuguese navi�  gator Bartolemeu Dias in 1488 on his return voyage to Portugal after finding  the southern limits of the African continent. Known for the stormy  weather and rough seas encountered there, the cape lies at the conver�  gence of warm currents from the Indian Ocean and cool currents from  Antarctic waters. A part of the Cape of Good Hope Nature Reserve estab�  lished in 1939, the cape was the site of the first Dutch settlement at Table  Bay in 1652.</p><p>Good Hope, Cape of (province) See Cape Province</p><p>Good Neighbour Policy Popular name for the policy toward Latin  America pursued in the 1930s by Pres. Franklin D. Roosevelt. In a marked  departure from its traditional interventionism, which was abhorrent to  Latin Americans, the U.S. repudiated its assumed right to intervene unilat�  erally in Latin American affairs, abrogated most provisions of the Piatt  Amendment (1901), which had restricted the national sovereignty of Cuba,  and withdrew its Marines from Haiti. U.S. anticommunist policies after  World War II led to renewed distrust between the U.S. and Latin America  and brought an end to the noninterventionism of the Good Neighbour  Policy.</p><p>Goodall, Jane (b. April 3,1934, London, Eng.) British ethologist. Soon  after finishing high school, she fulfilled her childhood ambition of traveling  to Africa, where she assisted Louis Leakey (see Leakey family), who sug�  gested she study chimpanzees. She received a Ph.D. from Cambridge Uni�  versity for her work and remained at the research centre she founded in  Gombe, Tanz., until 1975. In 1977 she cofounded the Jane Goodall Institute  for Wildlife Research, Education, and Conservation in the U.S. Her obser�  vations established, among other things, that chimpanzees are omnivorous  rather than vegetarian, can make and use tools, and have complex and  highly developed social behaviours. Noteworthy among her writings are In  the Shadow of Man (1971) and The Chimpanzees of Gombe (1986). She  was made a Dame of the British Empire in 2003.</p><p>Goodman, Benny orig.

Goodman formed a big band in 1934, using arrangements by Fletcher  Henderson. The band�s sensational broadcast from Los Angeles�s Palo-  mar Ballroom in 1935 is seen as the beginning of the swing era. Good�  man�s band featured trumpeters Bunny Berigan, Ziggy Elman, and Harry  James and drummer Gene Krupa, all of whom would establish big bands  of their own. Goodman�s small group was among the first racially inte�  grated ensembles known to a wide public.

In the late 1940s he and Bill Todman  developed hit radio shows such as Stop the Music (1947) and Hit the  Jackpot (1948), and long-running television game shows including  What�s My Line? (1950-67), I�ve Got a Secret (1952-67), To Tell the  Truth (1956-67), and The Price Is Right (1957-64). He received an Emmy  Award for lifetime achievement in 1990.</p><p>Goodyear, Charles (b. Dec. 29, 1800, New Haven, Conn., U.S.�d.  July 1, 1860, New York, N.Y.) U.S. inventor of the vulcanization process  that permitted the commercial use of rubber. Interested in treating rubber  so that it would lose its adhesive quality and not melt, he discovered vul�  canization in 1839 when he accidentally dropped a rubber-sulfur mixture  onto a hot stove. The process would prove profoundly important for the  future uses of rubber. He patented it in 1844 but had to fight numerous  patent infringements in the U.S. and Europe. He never profited from his  discovery, and he died in debt.

After  earning a law degree from Moscow  State University (1955), he rose  through the ranks to become a full  Politburo member (1980) and gen�  eral secretary of the Communist Party  of the Soviet Union (1985-91). His  extraordinary reform policies of  glasnost and perestroika were resisted  by party bureaucrats; to reduce their  power, Gorbachev changed the  Soviet constitution in 1988 to allow  multicandidate elections and  removed the monopoly power of the  party in 1990. He cultivated warmer  relations with the U.S., and in  1989-90 he supported the demo�  cratically elected governments that  replaced the communist regimes of  eastern Europe. In 1990 he was awarded the Nobel Peace Prize. Russia�s  economic and political problems led to a 1991 coup attempt by hard�  liners. In alliance with president Boris Yeltsin, Gorbachev quit the Com�  munist Party, disbanded its Central Committee, and shifted political  powers to the Soviet Union�s constituent republics. Events outpaced him,  and the various republics formed the Commonwealth of Independent States  under Yeltsin�s leadership.

He was named imperial chancellor in 1866. He renounced the  ban on Russian warships on the Black Sea (1870) and allied Russia with  Germany and Austria-Hungary in the Three Emperors' League (1873). His  influence waned when he was unable to maintain the League. At the con�  clusion of the Russo-Turkish War, he did little to shape the Treaty of San  Stefano, which punished the defeated Turks, or its replacement at the  Congress of Berlin, a settlement that was far less favourable to Russia.</p><p>gordian worm See horsehair worm</p><p>Gordimer, Nadine (b.

Oct. 15,</p><p>1946, Niirnberg) German Nazi  leader. He fought in World War I  with the German air force. In 1922  he joined the Nazi Party and was  given command of the SA. After the  abortive Beer Hall Putsch, he escaped  to Austria, then returned to Germany  (1927) and was elected to the Reich�  stag. Chosen president of the Reich�  stag (1932), his power mounted after  Adolf Hitler was named chancellor in  1933. As Hitler�s most loyal sup�  porter, Goring held numerous posts,  including minister of the interior in  Prussia, where he established the  Gestapo. He also became head of the  German air force (Luftwaffe) and  minister of economic affairs. After  the Luftwaffe failed to win the Battle  of Britain, Goring lost face and semi-  retired to his country estate, where  he displayed the vast art collection  he had confiscated from Jews in occupied countries. In 1946 he was con�  demned to death at the Niirnberg trials but committed suicide by taking a  poison capsule.</p><p>Gorgon, carved marble mask of the  early 6th century bc; in the Acropolis  Museum, Athens</p><p>AUNARI�ART RESOURCE</p><p>Male gorilla (Gorilla gorilla).</p><p>KENNETH W.

Vosdanik Adoian (b. April 15, 1904,  Khorkom, Van, Turkish Armenia�d. July 21, 1948, Sherman, Conn.,  U.S.) Armenian-born U.S. painter. In 1920 he emigrated from Turkish  Armenia to the U.S. In 1925, after study at the Rhode Island School of  Design, he settled in New York City, where he studied and then taught at  the Grand Central School of Art (1926-31). He sought to assimilate the  aesthetic visions of Paul Cezanne, Joan Miro, and Pablo Picasso by paint�  ing in their styles until he encountered the emigre European Surrealists;  he then developed his own style of abstraction featuring biomorphic forms  that suggest plants or human viscera floating over a background of melt�  ing colours. After a series of personal calamities, he hanged himself. He  is the most important direct link between Surrealism and Abstract Expres�  sionism.</p><p>Gorky, Maksim orig. Aleksey Maksimovich Peshkov (b.</p><p>March 28, 1868, Nizhny Novgorod, Russia�d. June 14, 1936, Nizhny  Novgorod) Russian writer. After a childhood of poverty and misery (his  assumed name, Gorky, means �bitter�), he became a wandering tramp.  His early works offered sympathetic portrayals of the social dregs of Rus�  sia; they include the outstanding stories �Chelkash� (1895) and �Twenty-  Six Men and a Girl� (1899) and the successful play The Lower Depths  (1902). For his revolutionary activity, he spent the years 1906-13 abroad  as a political exile. His works include the autobiographical trilogy My  Childhood (1913-14), In the World (1915-16), and My Universities  (1923). Though initially an open critic of Vladimir Iuch Lenin and the Bol�  sheviks, after 1919 he cooperated with Lenin�s government. He lived in  Italy from 1921 to 1928. Upon his return to the U.S.S.R., he became the  undisputed leader of Soviet writers. When the Union of Soviet Writers  was established in 1934, he became its first president and helped estab�  lish Socialist Realism. He died suddenly while under medical treatment,  possibly killed on the orders of Joseph Stalin.</p><p>gorse Any of several related plants of the genera Ulex and Genista.  Common gorse ( U. europaeus ) is a spiny, yellow-flowered leguminous  shrub native to Europe and naturalized in the Middle Atlantic states and  on Vancouver Island. The large green spines and green twigs of Spanish  gorse (G. hispanica ), native to Spain and northern Italy, make it appear  evergreen in winter.

He directed several ballets before moving to Moscow  in 1900 as lead dancer and stage manager of the Bolshoi. He reshaped the  repertoire and introduced realism in scenery and costume, reviving inter�  est in the company.</p><p>Gortyn Vgor-.tlnN Ancient city, south-central Crete, Greece. Although  unimportant in Minoan times, it later displaced Phaestus as the dominant  city. It shared or disputed control of Crete with Knossos until the Roman  annexation in the 1st century bc, when it became the administrative capi�  tal of the Roman province of Crete and Cyrenaica. Among the city�s ruins,  the great civic law code of Gortyn, discovered in the 19th century, is the  most extensive account of Greek law before the Hellenistic Age.</p><p>goryd \g6-'ry6\ In Japanese mythology, vengeful spirits of the dead.  They were originally thought to be spirits of nobles who had been killed  unjustly and who avenged themselves by bringing about natural disasters,  disease, and wars. Identified by divination, they were appeased by being  granted status as gods. Later the belief arose that anyone could become a  goryd by willing it at the moment of death or by meeting an untimely  death. Various forms of exorcism and magical practices, such as the Bud�  dhist recitation of nembutsu (invoking the name of the Buddha Amida),  have been used to ward them off.</p><p>Gosden, Freeman F(isher); and Correll, Charles J.

They performed comedy routines in traveling vari�  ety shows before creating two black characters, Sam and Henry, for a  Chicago radio show (1926-28). In 1929 they broadened their appeal by  devising a larger cast of characters for a new nightly radio program, Amos  �n � Andy, thus creating the first situation comedy. As Amos the cab driver</p><p>and his sidekick, Andy, they became the mainstays of radio�s most popu�  lar program in the 1930s, and their popularity ensured the success of radio  broadcasting as a form of mass entertainment. Their show, which was  broadcast weekly, finally ended in 1954, partly in response to criticism  that its humour was offensive to blacks.</p><p>goshawk Vgas-,h6k\ Any of the more powerful accipiters (hawks in  the genus Accipiter), primarily short�  winged, forest-dwelling bird catch�  ers. Best known is the northern  goshawk, which reaches about 2 ft  (60 cm) in length with a 4.3-ft  (1.3-m) wingspread and has finely  barred gray plumage. Long used for  falconry, the goshawk takes game as  large as foxes and grouse. In the wild  it lives in temperate to northern for�  ests throughout the Northern Hemi�  sphere, though it has become rare in  the British Isles and is declining in  North America. Several other species  are found in the Southern Hemi�  sphere.</p><p>Gospel Any of the four New Testa�  ment books narrating the life and  death of Jesus. The Gospels of Mat�  thew, Mark, Luke, and John are placed  at the beginning of the New Testa�  ment and make up about half its total  text. Since the 18th century, the first  three have been called the Synoptic  Gospels, because they give similar accounts of the ministry of Jesus. The  term is also applied to apocryphal works of the 2nd century (e.g.. The  Gospel of Thomas).</p><p>gospel music Form of black American music derived from Pentecos�  tal church worship services and from spiritual and blues singing. Record�  ings of Pentecostal preachers� sermons were immensely popular among  African Americans in the 1920s. Taking the scriptural direction �Let  everything that breathes praise the Lord� (Psalm 150), Pentecostal  churches welcomed timbrels, pianos, banjos, guitars, other stringed instru�  ments, and even brass into their services. Choirs often featured the  extremes of female vocal range in antiphonal counterpoint with the  preacher�s sermon. Other forms of gospel music have included the sing�  ing and acoustic guitar playing of itinerant street preachers; individual  secular performers; and harmonizing male quartets, whose acts included  dance routines and stylized costumes. Gospel music�s principal compos�  ers and practitioners included Thomas A. Dorsey, who coined the term; the  Rev. C.A. Tindley (1851-1933); the blind wandering preacher Rev. Gary  Davis (1896-1972); Sister Rosetta Tharpe (1915�73), whose perfor�  mances took gospel into nightclubs and theatres in the 1930s; and Maha-  lia Jackson. Gospel music was a significant influence on rhythm and blues  and soul music, which have in turn strongly influenced contemporary gos�  pel music.</p><p>Gosplan \gos-'plan\ Central board that supervised various aspects of  the planned economy of the former Soviet Union. The name is an abbre�  viation of the Russian for �State Planning Committee.� Established in  1921, Gosplan originally advised the government but assumed a more  comprehensive planning role in 1928, when the First Five-Year Plan was  adopted in an effort to bring about rapid industrialization and collectiviza�  tion. Throughout the existence of the Soviet Union it was responsible for  translating general economic objectives outlined by the Communist Party  into specific national plans.

He wrote the literary histories 18th Century Literature  (1889) and Modern English Literature (1897), as well as biographies of  Thomas Gray, John Donne, Ibsen, and others, and introduced many works  by continental European writers to English readers. Many of his critical  essays were collected in French Profiles (1905), and his autobiography,  Father and Son (1907), has been much admired.</p><p>Goteborg \'y6e-ta-,b6r y \ or Gothenburg \'gath- 3 n-,b3rg\ City (pop.,  2001 est.: 471,267), southwestern Sweden. The country�s chief seaport  and second largest city, it lies along the Gota River estuary, about 5 mi  (8 km) above the Kattegat. Founded in 1603, the city was destroyed in  the Kalmar War with Denmark (1611-13) but was refounded in 1619.  Many of the early inhabitants were Dutch, who built urban canals and  laid out the city centre. A prosperous period began with the completion  of the Gota Canal (1832) and the start of a transoceanic shipping service.  It retains some historic architecture, and a moat still encircles the old part  of the city. The port�s principal exports are automobiles (Volvo), ball  bearings, and paper.</p><p>Goth Member of a Germanic people whose two branches, the  Ostrogoths and the Visigoths, harassed the Roman Empire for centuries.  Legend holds that the Goths originated in southern Scandinavia, crossed  to the southern shore of the Baltic Sea, and then migrated to the Black  Sea in the 2nd century. They raided the Roman provinces in Asia Minor  and the Balkan peninsula in the 3rd century and drove the Romans out  of the province of Dacia during the reign of Aurelian. In the 4th and 5th  centuries, the Visigoths smashed a Roman army, sacked the city of Rome,  and created a kingdom in Spain that would last until the Muslim con�  quests of the 8th century. The Ostrogoths established an important king�  dom in Italy in the late 5th century that was destroyed by Justinian in the  6th century. The adjective �Gothic� was applied disparagingly and inap�  propriately to medieval architecture by much later writers.</p><p>Gothic, Carpenter See Carpenter Gothic</p><p>Gothic architecture Architectural style in Europe that lasted from the  mid 12th century to the 16th century, particularly a style of masonry  building characterized by cavernous spaces with the expanse of walls  broken up by overlaid tracery. In the 12th�13th centuries, feats of engi�  neering permitted increasingly gigantic buildings. The rib vault, flying  buttress, and pointed (Gothic) arch were used as solutions to the problem  of building a very tall structure while preserving as much natural light as  possible. Stained-glass window panels rendered startling sun-dappled  interior effects. One of the earliest buildings to combine these elements  into a coherent style was the abbey of Saint-Denis, Paris (c. 1135-44).  The High Gothic years (c. 1250-1300), heralded by Chartres Cathedral,  were dominated by France, especially with the development of the Ray-  onnant style. Britain, Germany, and Spain produced variations of this  style, while Italian Gothic stood apart in its use of brick and marble rather  than stone. Late Gothic (15th-century) architecture reached its height in  Germany�s vaulted hall CHURCHes. Other late Gothic styles include the  British Perpendicular style and the French and Spanish Flamboyant style.</p><p>Gothic art Architecture, sculpture, and painting that flourished in West�  ern and central Europe in the Middle Ages. It evolved from Romanesque  art and lasted from the mid-12th century to the end of the 15th century.  Its loftiest form of expression is architecture, as in the great cathedrals of  northern Europe. Sculpture was closely tied to architecture and often used  to decorate the exteriors of cathedrals and other religious buildings. Paint�  ing evolved from stiff, two-dimensional forms to more natural ones. Reli�  gious and secular subjects were depicted in illuminated manuscripts.  Panel and wall painting evolved into the Renaissance style in Italy in the  15 th century, but retained its Gothic features until the early 16th century  elsewhere in Europe. See also Gothic architecture.</p><p>Gothic language Extinct Germanic language spoken by the Goths. Its  records antedate those of other Germanic languages by about four cen�  turies. Best known from a translation of the Bible into Gothic in ad 350,  it died out among the Ostrogoths after the fall of their kingdom in Italy  in the 6th century and among the Visigoths around the time of the Arab</p><p>conquest in 711. It persisted longer in the Crimea, where a form of Gothic  was spoken as late as the 16th century.</p><p>gothic novel European Romantic, pseudo-medieval fiction with a pre�  vailing atmosphere of mystery and terror. Such novels were often set in  castles or monasteries equipped with subterranean passages, dark battle�  ments, and hidden panels, and they had plots involving ghosts, madness,  outrage, superstition, and revenge. Horace Walpole�s Castle of Otranto  (1765) initiated the vogue, which peaked in the 1790s. Ann Radcliffe�s  The Mysteries of Udolpho (1794) and The Italian (1797) are among the  finest examples. Matthew Gregory Lewis�s The Monk (1796) introduced  more horrific elements into the English gothic. Gothic traits appear in  Mary Shelley�s Frankenstein (1818) and Bram Stoker�s Dracula (1897) and  in the works of many major writers, and they persist today in thousands  of paperback romances.</p><p>Gothic Revival Architectural movement (c. 1730-c. 1930) most com�  monly associated with Romanticism. The first nostalgic imitation of  Gothic architecture appeared in the 1 8th century, when scores of houses  with castle-style battlements were built in England, but only toward the  mid-19th century did a true Gothic Revival develop. The mere imitation  of Gothic forms and details then became its least important aspect, as  architects focused on creating original works based on underlying Gothic  principles. French architects, particularly E.-E. Viollet-le-Duc, were the  first to think about applying the Gothic skeleton structure to a modern  age. Though the movement began losing force toward the end of the cen�  tury, Gothic-style churches and collegiate buildings continued to be con�  structed in Britain and the U.S. well into the 20th century.</p><p>Gothic script See black letter script</p><p>Gotland Island (pop., 2002 est.: 57,458) and county, southeastern Swe�  den.

By the 12th century Gotland�s traders dominated the  routes between Russia and western Europe. German merchants, who  settled in the major town and current county capital, Visby, brought Got�  land into the Hanseatic League. It was at the height of its prosperity when  it was taken by the Danish in 1361. It was finally returned to Sweden in  1645 and was fortified in the late 19th century.

They have a total area of 266 sq mi  (689 sq km), stretching about 60 mi (100 km) from northeast to south�  west. The islands were a gateway to Japan for the introduction of Chi�  nese culture. Fishing is the major activity in the northern islands;  agriculture predominates in the southern islands.</p><p>gotra Vgo-troX Lineage segment within an Indian caste, indicating com�  mon descent from a mythical ancestor. Marriage by members of the same  gotra was traditionally prohibited. The custom was intended to prevent  inbreeding as well as to broaden the influence of each gotra through mar�  riage alliances.

Sent to France at age 13 to  study music, he quickly became known throughout Europe as a piano vir�  tuoso and a composer of exotic piano works. He returned in 1853 and  toured the U.S., West Indies, and South America. Though he wrote operas  and symphonies, he is known for his more than 200 piano pieces, includ�  ing La Bamboula, Le Bananier, Le Banjo , L�Union, and The Dying Poet.

A charter member of Czechoslova�  kia�s Communist Party (1921), he became its leader in 1927 and a mem�  ber of the Czechoslovak parliament in 1929. Opposed to the Munich  agreement, he lived in Moscow through World War II, making several  broadcasts to the Czechoslovak underground. After the war, he was  appointed deputy premier (1945�46), then premier (1946-48). Inaugu�  rated as president in 1948 after Edvard Benes�s resignation, he quickly  consolidated his position, purging rivals and adopting a Stalinist model  of government, and served until his death.</p><p>gouache \'gwash\ Opaque watercolour. Also known as poster paint,  designer�s colour, and body colour, it differs from transparent waterco�  lour in that the pigments are bound by liquid glue, which is used as a  thinner. The addition of white pigment lightens the tone and lends opac�  ity. Gouache paints dry to a matte finish and, if desired, without visible  brush marks. They can be applied thinly or thickly. A wide range of  colours are available, including fluorescent and metallic pigments. The  suede finish and crisp lines characteristic of many Indian and Islamic  miniature paintings is produced by this medium; it is used in Western  screen and fan decoration and was used by modem artists such as Georges  Rouault and Paul Klee.</p><p>Goulart \gii-'lart\, Joao (Belchior Marques) (b.

Getulio Vargas, in whose admin�  istration he served as minister of labour, industry, and commerce. Elected  vice president (1956-61), he became president when Pres. Janio Quadros  resigned. He undertook a program of radical reforms, winning passage of  a law limiting the amount of profits that foreign companies could export.

He studied cartooning  through a correspondence school. His �Dick Tracy� action comic strip,  first distributed in 1931 by the Chicago Tribune-New York News Syndi�  cate, became the first popular cops-and-robbers series. Drawn with hard  outlines and accurate in the details of crime and criminal investigation,  the widely syndicated strip featured a clean-cut detective with a jutting  jaw, whose methods made him the nemesis of a gallery of grotesquely  caricatured criminals. Gould retired from the strip in 1977.</p><p>Gould VgiildV Glenn (Herbert) (b. Sept. 25, 1932, Toronto, Ont.,  Can.�d. Oct. 4,1982, Toronto) Canadian pianist. The acclaim that greeted</p><p>Gould�s first recording of Bach�s Goldberg Variations (1955) led him to  abandon his interest in composition and to instead develop an international  career as a pianist. His interpretations of Bach (and occasionally of other  composers) set a new standard with their technical brilliance and subtle  intelligence. Famously eccentric, he often wore gloves while playing and  was intensely hypochondriac. Never happy performing, in 1964 he left the  concert stage forever for the recording studio. He later composed radio  �documentaries� (including The Idea of North) that fall somewhere  between typical examples of the genre and musique concrete.</p><p>Gould \'giild. Jay orig. Jason Gould (b. May 27, 1836, Roxbury,  N.Y., U.S.�d. Dec. 2, 1892, New York, N.Y.) U.S. railroad executive,  speculator, and robber baron. Educated in local schools, he worked as a  surveyor and then operated a tannery. By 1859 he was speculating in the  stocks of small railways. In 1867 he became a director of the Erie Rail�  road; in the following year he joined with Daniel Drew and James Fisk to  prevent Cornelius Vanderbilt from buying control of the company. To this  end he engaged in outrageous financial manipulations, including the issue  of fraudulent stock and the payment of lavish bribes to New York state  legislators to legalize the stock�s sale. He and Fisk then joined forces with  William Marcy Tweed to profit from further stock manipulations. In 1869  they attempted to comer the gold market, causing the Black Friday panic.  In 1872 public outcry forced Gould to cede control of the Erie Railroad.  With a fortune of $25 million, he began buying large blocks of stock in  Union Pacific Railroad Company and acquired control of that company by  1874. By 1881 he owned 15% of all U.S. rail mileage. Having made large  profits by manipulating the company�s stock, he pulled out of the com�  pany in 1882 and began building a new rail system southwest of St. Louis  that by 1890 included half the region�s rail mileage. In 1881 he gained  control of Western Union Corp., and he owned the New York World news�  paper from 1879 to 1883. He remained ruthless, unscrupulous, and friend�  less to the end.</p><p>Gould, Shane (b. Nov. 23, 1956, Sydney, Austl.) Australian swimmer.

With Niles Eldredge  (b. 1943), he developed the controversial theory of punctuated equilib�  rium (1972), a revision of Darwinism that proposed that the evolutionary  creation of new species occurs in rapid bursts over periods as short as  thousands of years, which are followed by long periods of stability. He  was widely known as a popularizing writer on biological and evolution�  ary topics, especially in Natural History magazine; his numerous books  include The Panda�s Thumb (1980), The Mismeasure of Man (1981), and  The Structure of Evolutionary Theory (2002).</p><p>Gounod \gu-'no\, Charles (Francois) (b.

Generally deep-bodied and small-mouthed, they include  the giant gourami (Colisa fasciata), a blue-green and reddish brown fish  5 in. (12 cm) long; the dwarf gourami (C. lalia ), 2.5 in. (6 cm) long,  brightly striped in red and blue; and the kissing gourami ( Helostoma tem-  mincki), a greenish or pinkish white fish noted for its �kissing� activities.</p><p>gourd Any of certain hard-shelled food and ornamental plants of the  family Cucurbitaceae (order Violales), including SQUASHes and pumpkins.  Most species are prostrate or climb by tendrils. They are annual herba�  ceous plants native to temperate and tropical areas. Gourds are generally  low in nutrients; one exception is winter squash (certain cultivars of  Cucurbita maxima, C. moschata, C. pepo, etc.). The shells of many gourds  have made them useful as containers and utensils. Colourful and oddly  shaped gourds are picked for ornamental use.</p><p>Gourmont \gur-'mo n \, Remy de (b. April 4, 1858, Bazoches-en-  Houlmes, France�d. Sept. 27, 1915, Paris) French novelist, poet, play�  wright, and philosopher. He worked 10 years at the national library; his  dismissal resulted from an allegedly unpatriotic article in the Mercure de  France, a journal he had cofounded. A painful skin disease later kept him  a semirecluse. One of the most intelligent critics from the Symbolist move�  ment, he had a major role in disseminating its aesthetic doctrines. His 50  published volumes are mainly collections of essays.</p><p>gout Hereditary metabolic disorder in which excess uric-acid salts, nor�  mally excreted in urine, are deposited as needle-sharp crystals in joints,  causing attacks of severe inflammation. The most common site is the base  of the big toe. One of the oldest diseases in medical literature, gout is far  more common in men. Attacks usually do not begin until middle age. They  cause heat, redness, and extreme tenderness and pain and often subside  in a week or two. Colchicine is used to treat acute attacks. Drugs such as  allopurinol inhibit uric-acid synthesis.</p><p>government Political system by which a body of people is adminis�  tered and regulated. Different levels of government typically have differ�  ent responsibilities. The level closest to those governed is local  government. Regional governments comprise a grouping of individual  communities. National governments nominally control all the territory  within internationally recognized borders and have responsibilities not  shared by their subnational counterparts. Most governments exercise  executive, legislative (see legislature), and judicial (see judiciary) powers and  split or combine them in various ways. Some also control the religious  affairs of their people; others avoid any involvement with religion. Politi�  cal forms at the national level determine the powers exercised at the sub�  national levels; these have included autocracy, democracy, fascism,  monarchy, ougarchy, plutocracy (government by the wealthy), theocracy,  and TOTALITARIANISM.</p><p>government budget Forecast of governmental expenditures and rev�  enues for the ensuing fiscal year. In modern industrial economies, the  budget is the key instrument for the execution of government economic  policies. Because government budgets may promote or retard economic  growth in certain areas of the economy and because views about priori�  ties in government spending differ widely, government budgets are the  focus of competing political interests. In the U.S. the federal budget is  prepared by the president�s Office of Management and Budget. The U.S.  Congress has considerable input, influencing the budget�s preparation  through negotiations with the president and considering it in detail on its  official submission to Congress.</p><p>governor In technology, a device that automatically maintains the  rotary speed of an engine within reasonably close limits regardless of the  load. A typical governor regulates an engine�s speed by varying the rate  at which fuel or working fluid is furnished to it. Nearly all governors work  by centrifugal force and consist of a pair of masses rotating about a spindle  driven by the engine and kept from flying outward, usually by springs.  With an increase in speed, the controlling force of the springs is over�  come and the masses move outward, opening valves supplying the engine  with its working fluid or fuel. James Watt invented a governor for con�  trolling steam engines. Modem governors are used to regulate the flow  of gasoline to internal-combustion engines and the flow of steam, water, or  gas to various types of turbines. See also flywheel.</p><p>Gower Vgau-or, 'g6r\, John (b. 1330?�d. 1408, London?) English  poet. His works, in the tradition of courtly love and moral allegory,  strongly influenced other poets of his day. His friend Geoffrey Chaucer  called him �moral Gower.� His Speculum meditantis (c. 1374-78), writ�</p><p>ten in French, is an allegorical work on vices and virtues. Vox clamantis  (1385?), his major Latin poem, owes much to Ovid. His greatest work in  English is the Confessio Amantis (begun c. 1386), a long collection of  exemplary tales of love.</p><p>Goya (y Lucientes), Francisco (Jose) de (b. March 30, 1746,  Fuendetodos, Spain�d. April 16, 1828, Bordeaux, France) Spanish  painter and printmaker. He came to maturity in 1775 with the first of some  60 cartoons for the royal tapestry factory of Santa Barbara, painted  through 1792. In 1780 he was elected to the Royal Academy in Madrid  and in 1786 was appointed painter to Charles III. By 1799, under the  patronage of Charles IV, he had become the most successful and fashion�  able artist in Spain; his famous The Family of Charles TV was painted at  this time (1800). Though he welcomed his honours and success, the record  he left of his patrons and their society is ruthlessly penetrating. The eroti�  cism of his famous Naked Maja and Clothed Maja (c. 1800-05) caused  him to be summoned before the Inquisition in 1815. After an illness left  him permanently deaf in the 1790s, his work took on an exaggerated real�  ism that borders on caricature. His 80 Caprichos (�Caprices�; publ. 1799),  satirical prints attacking political, social, and religious abuses, marked an  outstanding achievement in the history of printmaking. When Napoleon  invaded Spain (1808-15), Goya produced the 82-etching series The  Disasters of War (1810-20). He settled in Bordeaux, France, in 1824,  resigned as court painter in 1826, and began working in lithography. He  had no immediate followers, but his work profoundly influenced 19th-  century European art.</p><p>Goyen \'kui-o,\ English Vgoi-onV, Jan Josephs(zoon) van (b. Jan.  13, 1596, Leiden, Neth.�d. April 27, 1656, The Hague) Dutch painter  and etcher. He studied in Leiden and Haarlem before settling at The Hague  in 1632. Confining himself primarily to the scenery of Holland, he painted  on wood panels; intricate detail, low horizons, and subtle atmospheric  effects characterize his work. He excelled at capturing the moods of sky  and water, Dutch cities, and lowland winter scenes. A prolific draftsman,  he also executed many landscape etchings. He had numerous imitators.  With Salomon van Ruysdael, he was the outstanding master of tonal land�  scape painting in 17th-century Holland.</p><p>Gozzoli \got-'ts6-le\, Benozzo orig.

Early in his career he assisted Lorenzo Ghiberti on the east doors of the  Baptistery in Florence and Fra Angelico on frescoes in Florence, Rome,  and Orvieto. His reputation today rests on the breathtaking fresco cycle  The Journey of the Magi (1459-61) in the chapel of Florence�s Medici-  Riccardi Palace. His work as a whole was undistinguished, however. He  painted several altarpieces and a series of 25 frescoes of Old Testament  scenes, now badly damaged, for the Camposanto in Pisa (1468-84).</p><p>Detail with Lorenzo de' Medici from "Procession of the Magi," fresco by Benozzo  Gozzoli, 1459; in the Medici-Riccardi Palace, Florence.</p><p>SCAIA�ART RESOURCE</p><p>GPS See Global Positioning System</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>786 i Graaff &#x25BA; Graham</p><p>Graaff, Robert Van de See Robert J.

She performed as a chorus-line dancer in 1930s musicals, then was featured  in musicals such as Down Argentine Way (1940) and Moon over Miami  (1941). Noted for her shapely legs, she became a top star and a favourite  pinup girl of U.S. troops in World War II. After the war, she starred in films  such as Mother Wore Tights ( 1947) and How to Marry a Millionaire (1953),  but as the film musical fell into decline so did her career.</p><p>Gracchus Vgra-kosV, Gaius Sempronius (b. c. 160�d. 121 bc,  Grove of Furrina, near Rome) Roman tribune (123-122 bc). He joined the  outcry over the murder of his brother, Tiberius Sempronius Gracchus and  helped implement his agrarian law. He combined the votes of plebeians  and equites to pass reforms aimed at curbing the corruption of the nobil�  ity. His attempts to extend citizenship to Rome�s Italian allies and more  freedom to plebeians were unpopular. Though he came from an aristo�  cratic family, his policies were seen by extreme conservatives as an  attempt to destroy the aristocracy. He committed suicide while under siege  on the Aventine Hill.</p><p>Gracchus, Tiberius Sempronius (b. c. 169�d. June 133 bc, Rome)  Roman aristocrat and tribune (133 bc). He sponsored agrarian reforms to  restore the class of small independent farmers on which the Roman  economy and military depended. Although a traditional system only 30  years before, it was seen as radical by his Senate enemies. He was assas�  sinated in a riot sparked by senatorial opponents angered by his unortho�  dox political tactics. His brother Gaius Sempronius Gracchus enforced his  reforms.</p><p>grace In Christian theology, the unmerited gift of divine favour, which  brings about the salvation of a sinner. The concept of grace has given rise  to theological debate over the nature of human depravity and the extent  to which individuals may contribute to their own salvation through free  will. Though in principle the ideas of merit and grace are mutually exclu�  sive, the question of whether grace may be given as a reward for good  works or for faith alone was important in the Protestant Reformation. There  has also been controversy over the means of grace: Roman Catholics,  Eastern Orthodox, and some Protestants believe that it is conferred  through the sacraments, while some other Protestants (e.g., Baptists) hold  that participation in grace results from personal faith alone. See also jus�  tification; ORIGINAL SIN.</p><p>Grace One of a group of Greek goddesses who personified charm and  beauty. Originally fertility goddesses, they were frequently associated  with Aphrodite. Their number varied in different legends, but often there  were three. They were sometimes said to be the daughters of Zeus and  Hera and sometimes of Helios and Aegle, daughter of Zeus.</p><p>Grace, W(illiam) G(ilbert) (b. July 18, 1848, Downend, Gloucester�  shire, Eng.�d. Oct. 23, 1915, London) Greatest cricketer in Victorian  England. Although he practiced medicine, cricket was his first love. Grace  evolved the modern principles of bat�  ting and achieved many notable per�  formances on rough and  unpredictable wickets such as are  unknown to modem players. In his  career in first-class cricket (1865�</p><p>1908), Grace scored 54,896 runs,  registered 126 centuries (100 runs in  a single innings), and, as a bowler,  took 2,876 wickets. In 84 matches for  Gentlemen versus Players, he  amassed 6,000 runs and took 271  wickets. In 1880 he was on the  English team that played the first Test  match against Australia in England.</p><p>grackle Any of several songbird  species (in the family Icteridae) hav�  ing iridescent black plumage and a  long tail; also called crow-blackbird.</p><p>Grackles use their stout, pointed bill  to snap up insects, dig grubs from the  soil, and kill small vertebrates,  including fishes and baby birds; they</p><p>can also crack hard seeds. The common grackle ( Quiscalus quiscula ) of  North America is about 12 in. (30 cm) long. The males of two Cassidus  species (boat-tailed and great-tailed grackles) have a long, deeply keeled  tail; these species are found in arid lands of the southwestern U.S. to Peru  and in salt marshes from New Jersey to Texas, where they are locally called  jackdaws. See also blackbird, mynah.</p><p>gradient In mathematics, a differential operator applied to a three-  dimensional vector-valued function to yield a vector whose three compo�  nents are the partial derivatives of the function with respect to its three  variables. The symbol for gradient is V. Thus, the gradient of a function  / written grad / or V/, is V/ = \f x + j f y + k f z where f x , f y , and f z are the  first partial derivatives of/and the vectors i, j, and k are the unit vectors  of the vector space.

Using Hermann von Helmholtz�s ophthalmoscope, he developed  several operations for eye disorders, including iridectomy (removal of part  of the iris) for glaucoma and lens extraction for cataract. He traced blind�  ness and visual defects in some cerebral disorders to optic-nerve inflam�  mation. Grafe sign (diagnostic for Graves disease) is failure of the upper  eyelid to follow the eyeball when looking downward. His writings include  a Manual of Comprehensive Ophthalmology (7 vol., 1874-80). He is con�  sidered the founder of modern ophthalmology.</p><p>graffiti Form of visual communication, usually illegal, involving the  unauthorized marking of public space by an individual or group. Tech�  nically the term applies to designs scratched through a layer of paint or  plaster, but its meaning has been extended to other markings. Graffiti is  widely considered a form of antisocial behaviour performed in order to  gain attention or simply for thrills. But it also can be understood as an  expressive art form. Derived from the Italian word grajfio (�scratch�),  graffiti (�incised inscriptions,� plural but often used as singular) has a long  history. It has been found in ancient Roman ruins, in the remains of the  Mayan city of Tikal in Central America, on rocks in Spain dating to the  16th century, and in medieval English churches. During the 20th century,  graffiti in the U.S. and Europe was closely associated with gangs. Graffiti  was particularly prominent in major urban centres throughout the world;  common targets were subways, billboards, and walls. In the 1990s there  emerged a new form of graffiti, known as �tagging,� which entailed the  repeated use of a single symbol or series of symbols to mark territory.</p><p>graft In horticulture, the act of placing a portion of one plant (called a  bud or scion) into or on a stem, root, or branch of another (called the  stock) in such a way that a union forms and the partners continue to grow.  Grafting is used for various puiposes: to repair injured trees, produce  dwarf trees and shrubs, strengthen plants� resistance to certain diseases,  retain varietal characteristics, adapt varieties to adverse soil or climatic  conditions, ensure pollination, produce multifruited or multiflowered  plants, and propagate certain species (such as hybrid roses) that can be  propagated in no other way. In theory, any two plants that are closely  related botanically and that have a continuous cambium can be grafted.  Grafts between species of the same genus are often successful and  between genera occasionally so, but grafts between families are nearly  always failures.

One gram is equal to 0.001 kg, about  0.035 oz, or 15.43 grains. The gram is very nearly equal to the mass of 1  cc of pure water at its maximum density. The gram of force is equal to  the weight of a gram of mass under standard gravity.

The stain reveals basic differences in the biochemical and struc�  tural properties of a living cell. A slide containing a smear of bacteria is  treated with a purple dye; the slide is then dipped in an iodine solution,  followed by an organic solvent (such as alcohol) that can dissolve the dye.  Gram-positive bacteria remain purple because they have a thick cell wall  that the solvent cannot easily penetrate; gram-negative bacteria lose their  colour because they have thin cell walls that allow the solvent to pen�  etrate and remove the dye.</p><p>gramadevata Vgra-ms-'da-vo-.taX Folk deities widely worshiped in  rural India.

They are worshiped in the form of stones or earthenware icons fixed in  simple shrines or set up under a village tree.</p><p>Grameen Bank In Bangladesh, first bank to specialize in small loans  for poor individuals. Originated by economist Muhammad Yunus, the  Grameen banking model is based on groups of five prospective borrowers  who meet regularly with Grameen Bank field managers. Typically, two of  the five prospective borrowers are granted loans. If, after a probationary  time period, the first two borrowers meet the terms of repayment, then  loans are granted to the remaining group members. Peer pressure acts as a  replacement for traditional loan collateral. Grameen became an indepen�  dent bank in 1983; headquartered in Dhaka, Bangladesh, it has more than  1,000 branches in the country. A typical Grameen loan ranges from $ 100 to  $400. The Grameen model has come to symbolize an efficient means of  helping the poor by providing them with opportunities to help themselves.  More than 90 percent of Grameen�s loan recipients have been women.</p><p>grammar Rules of a language governing its phonology, morphology,  syntax, and semantics; also, a written summary of such rules. The first  Europeans to write grammar texts were the Greeks, notably the Alexan�  drians of the 1st century bc. The Romans applied the Greek grammatical  system to Latin. The works of the Latin grammarians Donatus (4th cen�  tury ad) and Priscian (6th century) were widely used to teach grammar in  medieval Europe. By 1700, grammars of 61 vernacular languages had  been printed. These were mainly used for teaching and were intended to  reform or standardize language. In the 19th-20th centuries linguists began  studying languages to trace their evolution rather than to prescribe cor�  rect usage. Descriptive linguists (see Ferdinand de Saussure) studied spo�  ken language by collecting and analyzing sample sentences.  Transformational grammarians (see Noam Chomsky) examined the under�  lying structure of language (see generative gramaaar). The older approach  to grammar as a body of rules needed to speak and write correctly is still  the basis of primary and secondary language education.</p><p>Grammy Awards Annual awards given by the Recording Academy  (officially the National Academy of Recording Arts and Sciences). The  first Grammies (the name is a dimunitive of �gramophone�) were given  in 1958. The awards, which reflect the votes of the Academy�s large  membership of musicians, producers, and other music professionals, have  expanded considerably to reflect the variety of musical taste and produc�  tion; today awards are given in dozens of categories.</p><p>Grampian Mountains or Grampian Hills Mountain system,  Scotland. Extending across central Scotland, it forms a natural boundary  between the Scottish Highlands and Lowlands. Its highest peak, Ben Nevis,  is the highest mountain in Britain.</p><p>Grampians, the Mountain range, western Victoria, Australia. Com�  posed mainly of hard sandstone, the range is noted for deep gorges, weath�  ered rock formations, and wildflowers. The highest peak, Mount William,  rises to 3,827 ft (1,166 m). The range was named after the Grampian  Mountains of Scotland.</p><p>Gramsci Vgram-she\, Antonio (b. Jan. 23, 1891, Ales, Sardinia�d.  April 27, 1937, Rome, Italy) Italian intellectual and politician. After enter�  ing the University of Turin, he joined the Italian Socialist Party in 1914.  In 1921 he left the Socialists to found the Italian Communist Party (see  Democratic Party of the Left), and he spent two years in the Soviet Union.  In 1924 he became head of the party and was elected to the national leg�  islature. The party was outlawed by the fascist government of Benito  Mussolini in 1926, and Gramsci was arrested and imprisoned for 11 years;  in poor health, he was released to die at 46. His influential Letters from  Prison (1947) and other writings outline a version of communism less  dogmatic than Soviet communism. His work has influenced sociology,  political theory, and international relations.</p><p>Gran Chaco \gran-'cha-ko\ Spanish Chaco or El Chaco Lowland  alluvial plain, south-central South America. An arid lowland, it is bounded  by the Andes Mountains to the west and the Paraguay and Parana rivers  to the east; its northern and southern margins, generally considered to be  a marshy area in Bolivia and the Salado River in Argentina, respectively,  are less well defined. Its area is about 280,000 sq mi (725,000 sq km).  The region�s heartland, in the fork of the Paraguay and Pilcomayo rivers,  was fought over by Bolivia and Paraguay in the Chaco War (1932-35).  By a 1938 treaty a larger eastern part went to Paraguay and a smaller  western part to Bolivia. Chaco�s wildlife is abundant, and there are at least  60 known species of snakes. Cattle grazing is a major economic activity.  The area remains isolated and is only sparsely populated.</p><p>Gran Colombia \'gran-ko-'lom-be-a\ Former South American repub�  lic (1819-30). Formerly the Viceroyalty of New Granada, it included  roughly the modern nations of Colombia, Panama, Venezuela, and Ecua�  dor. Gran Colombia was formed in 1819 during the war for independence  from Spain, with its capital at Bogota. Revolutionary leader Simon Boli�  var was its creator and first president. Gran Colombia had a vigorous  existence during the war, but it was dissolved with the secession of Ven�  ezuela and Ecuador in 1830.</p><p>Gran Paradiso Vgran-.pa-ra-'de-zoV National Park Park, north�  western Italy. Established in 1836 as a hunting zone, in 1856 it became  the Royal Hunting Reserve of the Gran Paradiso, and in 1947 it received  national park status. It covers an area of 153,240 acres (62,000 hectares)  and extends along the upper Valle d'Aosta region; it contains the highest  peak in the Graian Alps, Gran Paradiso, at 13,323 ft (4,061 m). The ter�  rain is typically Alpine, with numerous glaciers and coniferous tree-lined  slopes.</p><p>Granada \gra-�na-tha\ City (pop., 2001: 240,661), capital of Granada  province, Andalusia autonomous community, southern Spain. Located at  the northwestern slope of the Sierra Nevada, it was the site of the Iberian  settlement Elibyrge in the 5th century bc and of the Roman Illiberis. As  the seat of the Moorish kingdom of Granada, it was the final stronghold  of the Moors in Spain, falling to Roman Catholic monarchs Ferdinand II  and Isabella I in 1492. Nearby is the Alhambra, as well as the Alcazaba  fortress that guarded it. The city has fine Renaissance, Baroque, and Neo�  classical architecture and is a major tourist centre. It has been the see of  an archbishop since 1493; the University of Granada was founded in 1526.</p><p>Granados \gra-'na-thos\ (y Campina), Enrique (b. July 27, 1867,  Lerida, Spain�d. March 24, 1916, at sea) Spanish composer. He studied  composition with Felipe Pedrell and concertized as a pianist. From 1901 he  taught at the Academia Granados, the music school he founded in Bar�  celona. He wrote four zarzuelas, including Maria del Carmen (1898), and  two �poemas� (also stage works), as well as songs and chamber works.  His fame rests on the piano suite Goyescas (1911). His opera of the same  name was performed successfully at New York�s Metropolitan Opera in  1916. Returning to Spain from this performance, Granados was drowned  when his ship was torpedoed by a German submarine.</p><p>Grand Alliance, War of the (1689-97) Third major war of Louis  XIV of France, in which his expansionist plans were blocked by an alli�  ance led by Britain, the United Provinces of the Netherlands, and the  Austrian Habsburgs. The deeper issue underlying the war was the rivalry  between the Bourbon and FIabsburg dynasties. Louis launched a campaign</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Grand Banks &#x25BA; Grand Trunk Railway I 789</p><p>in the 1680s to position the Bourbons for future succession to the Span�  ish throne. To oppose him, the Habsburg emperor Leopold I joined other  European nations in the League of Augsburg. The league proved ineffec�  tive, but in 1690 Britain, Brandenburg, Saxony, Bavaria, and Spain,  alarmed at Louis�s successes, joined with Leopold to form the Grand  Alliance. As war broke out in Europe and in overseas colonies, including  America (see King William's War), Louis found his military inadequately  prepared, and France suffered heavy naval losses. In 1695 Louis started  secret peace negotiations, which culminated in the Treaty of Rijswijk  (1697). The underlying conflict between the Habsburg and Bourbon rul�  ers and English-French conflicts remained unresolved and resurfaced four  years later in the War of the Spanish Succession.</p><p>Grand Banks Portion of North American continental shelf, in the  Atlantic Ocean. Lying southeast and south of Newfoundland, it is a noted  international fishing ground and extends 350 mi (560 km) north-south and  420 mi (675 km) east-west. The cold Labrador Current and the warm Gulf  Stream meet in its vicinity, causing heavy fogs. The banks were first  reported in 1498 by John Cabot. In 1977 Canada extended its fishing claim  to encompass most of the Grand Banks; it has since given limited fishing  rights to other countries.</p><p>Grand Canal Series of waterways in northern China that link Hang�  zhou with Beijing. Some 1,085 mi (1,747 km) in length, it is the world�s  longest man-made waterway. It was build to enable successive Chinese  regimes to transport surplus grain from the agriculturally rich Yangtze  (Chang) and Huai river valleys to feed the capital cities and large stand�  ing armies in the north. The oldest portion, in the south, may date from  the 4th century bc. Expanded over the centuries, it continues to be used  today for shipping and irrigation.</p><p>Grand Canyon Extensive canyon system cut by the Colorado River,  northwestern Arizona, U.S. Noted for its rock formations and coloration,  it is about 0.1-18 mi (0.2-29 km) wide and extends from northern Ari�  zona to Grand Wash Cliffs, near the Nevada border, a distance of about  277 mi (446 km). The deepest section, 56 mi (90 km) long, is within Grand  Canyon National Park, which covers the river�s length from Lake Powell  to Lake Mead. The surrounding plateau is 6,000-9,000 ft (1,800-2,750  m) above sea level, and the canyon is in places more than 1 mi (1.6 km)  deep. The national park, now containing 1,904 sq mi (4,931 sq km), was  created in 1919. The former Grand Canyon National Monument, estab�  lished in 1932, was added, with other lands, in 1975. In 1979 the Grand  Canyon was designated a UNESCO World Heritage site.</p><p>Grand Canyon series Major division of rocks in northern Arizona  dating from Precambrian time. The rocks of the series consist of about 10,600  ft (3,400 m) of quartz sandstones, shales, and thick sequences of carbonate  rocks. Spectacular exposures of these rocks occur in the Grand Canyon.</p><p>Grand Central Station Railroad terminal in New York City. It was  designed and built (1903-13) by Reed &amp; Stem in collaboration with the  firm of Warren &amp; Wetmore; the latter firm is credited with the aesthetics  of the huge structure. The concourse, with its 125-ft (43-m) ceiling vault  painted with constellations, was one of the largest enclosed spaces of its  time. A gem of the Beaux-Arts style, the terminal looks as though it could  have been transported from 1870s France. Atop the symmetrical main  facade is a large clock and sculptures of an American eagle and Roman  deities. In the late 20th century the station was lavishly restored; this res�  toration effort brought national attention to the importance of preserving  architectural landmarks.</p><p>Grand Falls See Churchill Falls</p><p>Grand Guignol \gra n -gen-'yol\ Short plays of violence, horror, and  sadism popular in 20th-century Parisian cabarets. The name probably  derives from the violent plots that featured the puppet Guignol. The plays  were performed mainly at the Theatre du Grand Guignol from 1897 to  1962. The genre was introduced into England in 1908, but it remained  mainly a Parisian theatrical form.</p><p>grand jury Jury that examines accusations against persons suspected  of committing a crime and, if the evidence warrants it, issues formal  charges on which the accused are later tried (see indictment). It does not  decide guilt or innocence, only whether there is �probable cause� to  believe that a person committed a crime. Public officials (prosecutors and  police) provide information and summon witnesses for the jury. The pro�  ceedings are usually secret. Some U.S. states have abolished the grand  jury and authorize indictments by prosecutors.</p><p>Grand National British steeplechase horse-racing event held annually  in Liverpool, Eng. Established in 1839, it attracts more attention through�  out the world than any other such event, because of its extreme difficul�  ties and dangers. The course is covered twice for a distance of 4.48 mi  (7.2 km), including 31 jumps, some of them spectacularly hazardous.</p><p>Grand Ole Opry Country music radio show in Nashville, Tenn., U.S.  Founded in 1925 by George Dewey Hay, the show was originally known  as the WSM Barn Dance ; it acquired its lasting name in 1926. Its music  developed from Dave Macon�s ballads of rural labourers in the 1920s,  through the string bands, cowboy music, and western swing of the 1930s,  and later back to the traditional music characterized by the career of Roy  Acuff. After World War II, the honky-tonk style of Ernest Tubb and later  Hank Williams, the bluegrass of Bill Monroe, and the singing of Eddy  Arnold (b. 1918) and Kitty Wells all became Opry staples, as did comedy  routines, notably those by Minnie Pearl (1912-96). In 1941 the Opry  became a live stage show. In 1974 it moved to the Opryland amusement  park and entertainment centre. The Opry initiated and promoted the cre�  ation of Nashville as the centre of country music.</p><p>Grand Portage National Monument Historic site, northeastern  corner of Minnesota, U.S. Located on Lake Superior near the Canadian  border, it was designated a national historic site in 1951 and a national  monument in 1958. It covers a 9-mi (14-km) overland trail from Lake  Superior�s northern shore that bypassed the obstacles to early canoe travel.  Used by early explorers, the portage marked the end of travel on the Great  Lakes and the beginning of the interior river route. The portage trail now  bisects the reservation of the Grand Portage tribe of the Minnesota  Chippewa Indians.</p><p>Grand Prix Vgra n -'pre\ racing Automobile racing in which formula  cars are run on closed highways or courses that simulate road conditions.  Formula cars are open-wheel, open-cockpit, rear-engine vehicles and are  generally smaller than those used in speedway races such as the India�  napolis 500. Grand Prix racing began in 1906 and today comprises more  than 15 major international events. Its popularity grew particularly from  the 1950s, when world championships were established.</p><p>Grand Rapids City (pop., 2000: 197,800), western Michigan, U.S.  Located on the Grand River, it was founded in 1826 as a trading post.  Ample lumber from nearby forests soon fueled a woodworking industry.  After Grand Rapids furniture was shown at the 1876 Centennial Exhibi�  tion in Philadelphia, the city became known as the furniture capital of  America. Its industry diversified with the advent of World War I, and  metal-based manufacturing thereafter exceeded furniture. Its public  library contains important collections of books on furniture design; its  educational institutions include Kendall College of Art and Design (1928).  It was the boyhood home of Pres. Gerald Ford.</p><p>Grand River See Neosho River</p><p>Grand Staircase-Escalante National Monument National  preserve, southern Utah, U.S. Created a national monument in 1996, it  covers 1.7 million acres (0.7 million hectares). Its western section has  cliffs and plateaus, and its eastern section has canyons along the Escal�  ante River. Dinosaur tracks have been found there. The area was once  inhabited by the Anasazi people.</p><p>Grand Teton Vte-,tan\ National Park National preserve, northwest�  ern Wyoming, U.S. In 1950 most of Jackson Hole National Monument  (a fertile valley) was incorporated into the park, which was established  in 1929 and now covers 484 sq mi (1,254 sq km). The snow-covered peaks  of its Teton Range are 7,000 ft (2,100 m) above the nearby Snake River  valley.</p><p>Grand Traverse Vtra-v9rs\ Bay Northeast arm of Lake Michigan,  indenting northwestern Michigan, U.S. Located off the coast of the Lower  Peninsula, the head of the bay is 32 mi (52 km) long and 12 mi (19 km)  wide. It is divided into the east and west arms by Old Mission Peninsula,  with Traverse City at its base. The Leelanau Peninsula lies west of the  bay, which is noted for its year-round fishing. The area is an important  summer resort region.</p><p>Grand Trunk Railway Early Canadian railway line, incorporated in  1852-53 to connect the key cities of eastern Canada with Portland, Me.  By completing its final link in July 1853 between Montreal and Portland,  it became North America�s first international railroad.

The unification of all four fundamental inter�  actions is sometimes called unified field theory. Such theories generally  predict that a proton decays into lighter particles. So far, no successful  GUTs have been devised.</p><p>Grande, Rio See Rio Grande</p><p>grande ecole \gra n -da-'kol\ (French: �great school�) Any of several  preeminent specialized institutions of higher learning in France. The Ecole  Poly technique was founded in 1794 to recruit and train technicians for  the army. The Ecole Normale Superieure serves mainly to prepare future  university and lycee (senior secondary-school) teachers. The Ecole Nor�  male d�Administration trains the highest ranks of civil servants. The inter�  nationally renowned College de France (founded 1530) is a research  institution that offers lectures by eminent scholars; it does not grant  degrees or certificates. Other grandes ecoles include institutes for  advanced study in social science, architecture, and the arts.</p><p>grandfather clause Constitutional provision enacted by seven South�  ern U.S. states (1895-1910) to deny suffrage to African American men.  It exempted descendants of men who voted before 1867 from meeting  new literacy and property requirements. Since African American men  were not granted voting rights until passage of the 15th Amendment in  1870, this clause effectively prevented them, and many impoverished and  illiterate whites, from voting. The U.S. Supreme Court declared such  clauses unconstitutional in 1915.</p><p>Grandi Ygran-de\, Dino, count di Mordano (b. June 4, 1895, Mor-  dano, Italy�d. May 21, 1988, Bologna) Italian politician. He made an  unsuccessful bid for leadership of Italy�s Fascists in 1921, losing to Benito  Mussolini, but then held a succession of high government posts (1924-  43), including foreign minister (1929-33). In July 1943, as chair of the  Grand Council of Fascism, he attacked Mussolini and proposed a motion  of no confidence; passage of the resolution deposed Mussolini. Grandi  fled to Lisbon, then moved to Brazil, but eventually returned to Italy.</p><p>Grandma Moses See Grandma Moses</p><p>Grange, Red orig. Harold Grange (b. June 13, 1903, Forksville,  Pa., U.S.�d. Jan. 28, 1991, Lake  Wales, Fla.) U.S. gridiron football  player. He had an outstanding colle�  giate career at the University of Illi�  nois, where in 1924 he ran for five  touchdowns in a single game against  the University of Michigan and  earned the nickname �the Galloping  Ghost.� In 1925 he joined the Chi�  cago Bears and embarked on a barn�  storming tour that stimulated public  interest in professional football.</p><p>After suffering a knee injury in 1927,  he was never again an effective run�  ner. He retired in 1934 and subse�  quently worked as a sportscaster.</p><p>Granger, Clive W.J. (b. Sept. 4,</p><p>1934, Swansea, Wales) Welsh econo�  mist. Granger attended the Univer�  sity of Nottingham (B.A., 1955;</p><p>Ph.D., 1959), where he later taught.</p><p>He also wrote numerous books, cov�  ering such subjects as time series  analysis and forecasting, statistical theory, and applied statistics. In the  1970s and �80s he developed techniques for analyzing time series data  with common trends. In particular, he created concepts and analytic meth�  ods to establish meaningful relationships between nonstationary variables,  such as exchange rates and inflation rates. He shared the 2003 Nobel Prize  for Economics with Robert F. Engle.</p><p>Granger movement Vgran-jorX Coalition of U.S. farmers, mainly in  the Midwest, that fought monopolistic grain-transport practices in the</p><p>1870s. Oliver H. Kelley (1826-1913), a U.S. Department of Agriculture  employee, organized the Patrons of Husbandry in 1867 to bring farmers  together to learn new farming methods. By the mid-1870s almost every  state had at least one branch, or Grange, and national membership passed  800,000. The Grangers influenced some states to pass regulatory legisla�  tion to counter the price-fixing by railroads and grain-storage facilities.  Outgrowths of the Granger movement included the Greenback and Popu�  list movements. The Grangers dropped to about 100,000 members by  1880; they rebounded in the early 20th century, but declined again sub�  sequently.</p><p>Granicus \gr3-'nl-k9s\, Battle of the (334 bc) First victory won by  Alexander the Great in his invasion of the Persian empire. Against heavy  odds at the Granicus River, Alexander�s army defeated the Persians under  Darius III, who fled. Alexander himself charged the Persian generals, kill�  ing two of Darius� relatives and almost losing his own life. The Mace�  donians reportedly lost only 115 men. The victory gave western Asia  Minor to Alexander, and most cities hastened to open their gates.</p><p>Granit \gra-'net\, Ragnar Arthur (b. Oct. 30, 1900, Helsinki,  Fin.�d. March 12, 1991, Stockholm, Swed.) Finnish-born Swedish  physiologist. His �dominator-modulator� theory states that in addition to  the retina�s three kinds of cone cells, which respond to different colours,  certain optic-nerve fibres (dominators) respond either to the whole spec�  trum or to specific colours (modulators). He also proved that light inhib�  its as well as stimulates optic-nerve impulses; other research helped  determine the nerve pathways and processes by which receptors in  muscles coordinate muscle action. He shared a 1967 Nobel Prize with  George Wald and Haldan Keffer Hartline.</p><p>granite Coarse- or medium-grained intrusive rock that is rich in quartz  and alkali feldspar. One of the most common rocks of the Earth�s crust, it  is formed by the cooling of magma. Granite was once used extensively as  paving blocks and building stone, but today its principal uses are as road�  way curbing, veneer for building faces, and tombstones. Granite charac�  teristically forms irregular masses of extremely variable size, ranging  from less than 5 mi (8 km) in maximum dimension to larger masses  (batholiths) that are often hundreds of square miles in area.</p><p>granodiorite \ l gra-no-'dl-o- l rlt\ Medium- to coarse-grained rock that  is one of the most abundant intrusive rocks. It contains quartz and is dis�  tinguished from granite by having more plagioclase feldspar than ortho-  clase feldspar; its other mineral constituents include hornblende, biotite,  and augite. Granodiorite is similar to granite in appearance but darker.</p><p>Grant, Cary orig. Archibald Alexander Leach (b.

U.S.  general and 18th president of the U.S. (1869-77). He served in the Mexican  War (1846�48) under Zachary Taylor. After two years� service on the  Pacific coast (1852-54), during which he attempted to supplement his army  pay with ultimately unsuccessful business ventures, he resigned his com�  mission. His decision might have been influenced by his fondness for alco�  hol, which he reportedly drank often during this period.

When the American  Civil War began (1861), he was  appointed brigadier general; his 1862  attack on Fort Donelson, Tenn., pro�  duced the first major Union victory.</p><p>He drove off a Confederate attack at  Shiloh but was criticized for heavy  Union losses. He devised the cam�  paign to take the stronghold of Vicks�  burg, Miss., in 1863, cutting the  Confederacy in half from east to  west. Following his victory at the  Battle of Chattanooga in 1864, he  was appointed commander of the  Union army. While Gen. William T.</p><p>Sherman made his famous march  across Georgia, Grant attacked forces  under Gen. Robert E. Lee in Virginia,  bringing the war to an end in 1865. Grant�s administrative ability and inno�  vative strategies were largely responsible for the Union victory. In 1868 his  successful Republican presidential campaign made him, at 46, the young�  est man yet elected president. His two terms were marred by administrative  inaction and political scandal involving members of his cabinet, including  the Credit Mobilier scandal and the Whiskey Ring conspiracy. He was more  successful in foreign affairs, where he was aided by his secretary of state,  Hamilton Fish. He supported amnesty for Confederate leaders and protec�  tion for the civil rights of former slaves. His veto of a bill to increase the  amount of legal tender (1874) diminished the currency crisis during the  next 25 years. In 1881 he moved to New York City; when a partner  defrauded an investment firm co-owned by his son, the family was impov�  erished. His memoirs were published by his friend Mark Twain.</p><p>granulite facies Vgran-yo-.lIt-'fa-shezN One of the major divisions of  the mineral facies classification of metamorphic rocks, encompassing  rocks that formed under intense temperature-pressure conditions (higher  than 950�F, or 500�C). The minerals found in the rocks of granulite facies  include hornblende, pyroxene, biotite, garnet, calcium plagioclase, and  quartz or olivine. See also amphibolite facies.</p><p>Granville-Barker, Harley (b. Nov. 25, 1877, London, Eng.�d.  Aug. 31, 1946, Paris, France) British producer, playwright, and critic. An  actor from age 15, he directed his own first play, The Marrying of Ann  Leete, in 1901. As comanager of the Court Theatre (1904-07) he produced  many of George Bernard Shaw�s early plays as well as plays by Henrik  Ibsen, Maurice Maeterlinck, and John Galsworthy, and also produced his  own The Voysey Inheritance (1905) and Waste (1907). He influenced  20th-century theatre with his naturalistic stagings of Shakespeare�s plays,  which emphasized continuous action on an open stage and rapid, lightly  stressed speech. He moved to Paris after World War I and there wrote  Prefaces to Shakespeare (1927�46), a series of books of criticism.</p><p>grape Any of the 60 plant species that make up the genus Vitis (family  Vitaceae), native to the northern tem�  perate zone, including varieties that  may be eaten as table fruit, dried to  produce raisins, or crushed to make  grape juice or wine. V. vinifera is the  species most commonly used in wine  making. The grape is usually a  woody vine, climbing by means of  tendrils. In arid regions it may form  an almost erect shrub. Botanically,  the fruit is a berry. Grapes contain  such minerals as calcium and phos�  phorus and are a source of vitamin  A. All grapes contain sugar (glucose  and fructose) in varying quantities depending on the variety.</p><p>grape hyacinth Any of the approximately 50 species of small bul�  bous perennial plants that make up the genus Muscari, in the lily family,  native to the Mediterranean region. Most species have dense clusters of  blue, white, or pink urn-shaped flowers borne at the tip of a leafless flower  stalk. Some species have a musky odour. Grape hyacinths often are  planted as spring-flowering garden ornamentals.</p><p>grape phylloxera V.fi-.lak-'sir-o, fo-Tak-so-roN Small, greenish yellow  insect {Phylloxera vitifoliae, order Homoptera) that is highly destructive  to grape plants in Europe and the western U.S. It sucks fluid from grape�  vines, causing galls to form on leaves and nodules on roots; eventually  the plants rot. It was introduced into Europe from the eastern U.S. in the  mid-19th century and within 25 years had almost destroyed the grape and  wine industries in France, Italy, and Germany. Vines were saved by graft�  ing European plants to rootstocks of resistant vines native to the U.S.  Hybrids and fumigants are used to combat the pest.</p><p>grape sugar See glucose</p><p>grapefruit Tree {Citrus paradisi ) of the rue family and its edible fruit.

Though histograms  and pie charts are also graphs, the  term usually applies to point plots on a coordinate system. For example, a  graph of the relationship between real numbers and their squares matches  each real number on a horizontal axis with its square on a vertical axis. The  resulting set of points in this case is a parabola. A graph of an inequality is  usually a shaded region on one side of a curve, whose shape depends not  only on the equation or inequality but on the coordinate system chosen.</p><p>graph theory Mathematical theory of networks. A graph consists of  vertices (also called points or nodes) and edges (lines) connecting certain  pairs of vertices. An edge that connects a node to itself is called a loop.  In 1735 Leonhard Euler published an analysis of an old puzzle concerning  the possibility of crossing every one of seven bridges (no bridge twice)  that span a forked river flowing past an island. Euler�s proof that no such  path exists and his generalization of the problem to all possible networks  are now recognized as the origin of both graph theory and topology. Since  the mid-20th century, graph theory has become a standard tool for ana�  lyzing and designing communications networks, power transmission sys�  tems, transportation networks, and computer architectures.</p><p>graphic design The art and profession of selecting and arranging  visual elements�such as typography, images, symbols, and colours�to  convey a message to an audience. Sometimes graphic design is called  �visual communications.� It is a collaborative discipline: writers produce  words and photographers and illustrators create images that the designer  incorporates into a complete visual message. Although graphic design has  been practiced in various forms throughout history, it emerged as a spe�  cific profession during the job-specialization process that occurred in the  late 19th century. Its evolution has been closely bound to developments  in image making, typography, and reproduction processes. Prominent  graphic designers include Jules Cheret, Piet Zwart, Paul Rand, Alexey  Brodovitch, Milton Glaser, and David Carson.</p><p>graphical user interface (GUI) Computer display format that  allows the user to select commands, call up files, start programs, and do  other routine tasks by using a mouse to point to pictorial symbols (icons)  or lists of menu choices on the screen as opposed to having to type in text  commands. The first GUI to be used in a personal computer appeared in  Apple Computer�s Lisa, introduced in 1983; its GUI became the basis of  Apple�s extremely successful Macintosh (1984). The Macintosh�s GUI  style was widely adapted by other manufacturers of personal computers  and PC software. In 1985 Microsoft Corp. introduced Windows, a GUI  (which later grew into an operating system) that gave MS-DOS-based</p><p>Ulysses S.

It is dark gray to black, opaque, and very soft. Its lay�  ered structure, with rings of six atoms arranged in widely spaced parallel  sheets, gives it its slippery quality. It occurs in nature and is used (mixed  with clay) as the �lead� in pencils. It is also used in lubricants, crucibles,  polishes, arc lamps, batteries, brushes for electric motors, and nuclear  reactor cores.</p><p>graptolite Vgrap-to-.lItX Any member of an extinct group of small,  aquatic colonial invertebrates that first became apparent during the Cam�  brian Period and persisted into the Early Carboniferous Period (354-323  million years ago). Graptolites were floating animals that had tentacles  and a hard outer covering. They most often have been preserved as  impressions on black shales. Graptolite fossils show a gradual develop�  ment through time, and evolutionary relationships between different grap�  tolite groups have been discovered and analyzed.</p><p>grass Any of many low, green, nonwoody plants that make up the fami�  lies Poaceae (or Gramineae), Cyperaceae (sedges), and Juncaceae (RUSHes).  Only the approximately 8,000-10,000 species in the family Poaceae are  true grasses. They are the most economically important of all flowering  plants because of their nutritious grains and soil-forming function, and they  are the most widespread and most numerous of plants. The cereal grasses  include wheat, com, rice, rye, oats, barley, and millet. Grasses provide for�  age for grazing animals, shelter for wildlife, and construction materials,  furniture, utensils, and food for humans. Some species are grown as garden  ornamentals, cultivated as turf for lawns and recreational areas, or used as  cover plants for erosion control. Most have hollow, segmented, round  stems, bladelike leaves, and extensively branching fibrous root systems.</p><p>Grass \'gras\, Gunter (Wilhelm) (b. Oct. 16, 1927, Danzig) German  novelist, poet, and playwright. Grass  was involved in the Hitler Youth,  was drafted at age 16 and wounded  in battle, and became a prisoner of  war. His extraordinary first novel,</p><p>The Tin Drum (1959), brought him  international fame, and he became  the literary spokesman for the Ger�  man generation that grew up in the  Nazi era. Together with Cat and  Mouse (1961) and Dog Years (1963),  it forms a trilogy set in Danzig (now  Gdansk, Pol.). His other works, all  politically topical, include The  Flounder (1977); The Call of the  Toad (1992), about the uneasy rela�  tionship between Poland and reuni�  fied Germany; A Broad Field (1995),  controversial for expressing his view  that reunification was a mistake; and  My Century (1999). He received the Nobel Prize for Literature in 1999.</p><p>grasshopper Any of the leaping insects of the family Acrididae (short�  horned grasshoppers) or Tettigoni-  idae (long-horned grasshoppers),  both in the order Orthoptera. Grass�  hoppers are most common in tropical  forests, semiarid regions, and grass�  lands. Colours range from green to  olive or brown, sometimes with yel�  low or red markings. Grasshoppers  eat plant material and may damage  crops. Some species are more than 4  in. (11 cm) long. The male can pro�  duce a buzzing sound either by rub�  bing its front wings together or by rubbing toothlike ridges on the hind legs  against a raised vein on each front wing. Grasshoppers are a favourite food  of many birds, frogs, and snakes. See also katydid; locust.</p><p>Grateful Dead U.S. rock group. It was formed in San Francisco in the  mid-1960s by Jerry Garcia (1942-95) on guitar, Phil Lesh (b. 1940) on  bass, Ron (�Pigpen�) McKernan (1945-73) on keyboards, Bob Weir (b.</p><p>1947) on guitar, and Bill Kreutzmann (b. 1946) on drums. The Grateful  Dead emerged from the Haight-Ashbury psychedelic-drug-and-music  scene, later gaining fame for performing at the Monterey Pop Festival  (1967) and Woodstock. Though they regularly released albums, their  focus was on live music. They became one of the country�s most suc�  cessful touring bands, known for Garcia�s marathon four-hour musical  meanderings and for their entourage of �Deadheads,� a devoted legion of  nomadic fans who followed the band in spirited makeshift communities.  In the late 1980s a new generation of fans made the Grateful Dead the  most successful touring band in the world. They stopped touring after  Garcia died of a heart attack at a drug rehabilitation centre.</p><p>Gratian Vgra-shonV Latin in full Flavius Gratianus Augustus (b.</p><p>359, Sirmium, Pannonia�d. Aug. 25, 383, Lugdunum, Lugdunensis)  Roman emperor (r. 367-83). He originally shared the office with his  father, Valentinian I (r. 364-75), and his uncle, Valens (r. 364-78). He later  shared authority with his 4-year-old half brother, who was supported by  the army. Following his uncle�s death at the disastrous Battle of Adrian-  ople, he became ruler of the Eastern Empire and summoned Theodosius I  to share power with him. Influenced by St. Ambrose, Gratian omitted the  words pontifex maximus (�supreme priest�) from his title. He was mur�  dered opposing the usurper Magnus Maximus.</p><p>Grattan \'gra-t 3 n\, Henry (b. July 3, 1746, Dublin, Ire.�d. June 6,  1820, London, Eng.) Irish politician. He entered the Irish Parliament in  1775 and, as a brilliant orator, soon became the leading spokesperson of  the Irish nationalist agitation. His movement gained momentum; he forced  the British in 1779 to remove restraints on Irish trade and in 1782 to relin�  quish their right to legislate for Ireland. In 1800 he headed the unsuc�  cessful opposition to the union of England and Ireland. In 1805 he was  elected to the English House of Commons, where he fought for Catholic  emancipation for his last 15 years.</p><p>gravel Aggregate of more or less rounded rock fragments coarser than  sand (i.e., more than 0.08 in., or 2 mm, in diameter). Gravel beds in some  places contain heavy metallic ore minerals, such as cassiterite (a major  source of tin), or native metals, such as gold, in nuggets or flakes. Depos�  its accumulate in parts of stream channels or on beaches where the water  moves too rapidly to permit sand to remain. Because of changing condi�  tions, gravel formations generally are more limited and more variable in  coarseness, thickness, and configuration than sand or clay deposits. In  many regions gravel terraces (or raised beaches) extend great distances  inland, indicating that the sea at one time stood higher than it does today.  Gravels are widely used building materials.</p><p>Graves, Michael (b. July 9, 1934, Indianapolis, Ind., U.S.) U.S. archi�  tect and designer. He studied at Harvard University and in 1962 began a  long teaching career at Princeton University while designing private  houses in the abstract and austere style of orthodox Modernism. In the  late 1970s he rejected Modernist expression and began seeking a larger,  postmodernist vocabulary. The hulking masses of the Portland Building  in Portland, Ore. (1980), and the Humana Building in Louisville, Ky.  (1982), display his highly personal. Cubist rendering of such Classical  elements as colonnades and loggias. Though considered somewhat awk�  ward, these and his later buildings (e.g., Indianapolis Art Center, 1996)  have been acclaimed for their ironic interpretation of traditional forms.  Among his later projects were the restoration of the Washington Monu�  ment (2000) and the creation of a line of household items, including  kitchenware and furniture, for the discount retailer Target.</p><p>Graves, Robert (von Ranke) (b. July 24/26, 1895, London,  Eng.�d. Dec. 7, 1985, Deya, Majorca, Spain) British man of letters. He  served as an officer at the Western Front during World War I and his first  three volumes of poetry were published during that time; they include  some of the finest English love poems of the century. In 1926 he began  a 13-year relationship with the American poet Laura Riding (1901-91),  with whom he founded a press, briefly published a journal, and collabo�  rated as a writer. After 1929 he lived principally in Majorca, Spain. The  most famous of his more than 120 books are Good-bye to All That (1929),  a grim memoir of the war; the historical novel I, Claudius (1934; tele�  vised in 1976); and erudite, controversial studies in mythology, notably  The White Goddess (1948).</p><p>Graves, Robert James (b. 1796, Dublin, Ire.�d.

His Clinical Lec�  tures on the Practice of Medicine (1848) established his reputation. He  introduced timing of the pulse by watch and giving patients with fevers  nourishment instead of withholding it. He was a leader of the Irish (Dub�  lin) school of diagnosis, which stressed observation of patients, and was  one of the first to fully describe exophthalmic goitre (Graves disease).</p><p>Graves disease or toxic diffuse goitre or exophthalmic</p><p>\,ek-saf-'thal-mik\ goitre Most common type of hyperthyroidism (over�  secretion of thyroid hormone), usually with goitre and exophthalmos (eye�  ball protrusion). Increased thyroid hormone levels result in increased  cardiac output, rapid heartbeat, and possibly heart failure. Stress may  trigger a severe worsening (thyroid storm), which can lead to circulatory  collapse and death. Graves disease is considered an autoimmune disease.  It can sometimes be controlled by drugs; severe cases require partial or  total removal of the thyroid gland. Graves disease is named after Robert  James Graves, one of the first physicians to fully describe the disease.</p><p>gravitation Universal force of attraction that acts between all bodies  that have mass. Though it is the weakest of the four known forces, it shapes  the structure and evolution of stars, galaxies, and the entire universe. The  laws of gravity describe the trajectories of bodies in the solar system and  the motion of objects on Earth, where all bodies experience a downward  gravitational force exerted by Earth�s mass, the force experienced as  weight. Isaac Newton was the first to develop a quantitative theory of  gravitation, holding that the force of attraction between two bodies is pro�  portional to the product of their masses and inversely proportional to the  square of the distance between them. Albert Einstein proposed a whole new  concept of gravitation, involving the four-dimensional continuum of  space-time which is curved by the presence of matter. In his general theory  of relativity, he showed that a body undergoing uniform acceleration is  indistinguishable from one that is stationary in a gravitational field.</p><p>gravitational radius See Schwarzschild radius</p><p>gravity, centre of Imaginary point where the total weight of a mate�  rial body may be thought to be concentrated. Since weight and mass are  proportional, the same point may also be called the centre of mass, but  the centre of mass does not require a gravitational field. A body�s centre  of gravity may coincide with its geometric centre, especially if the body  is symmetric and composed of homogeneous material. In asymmetric,  unhomogeneous, or hollow objects, the centre of gravity may be at some  distance from the geometric centre or even at a point in space external to  the object, such as between the legs of a chair.</p><p>gravure \gr3-'vyur\ printing Printing processes used for catalogs,  magazines, newspaper supplements, cartons, floor and wall coverings,  textiles, and plastics. The Bohemian Karel Klfc made photogravure a  practical commercial process in 1878. An image is etched in the copper  surface of the printing cylinder as pits or wells of different depths. In  rotogravure printing, the cylinder rotates through a trough filled with fast�  drying ink. A thin steel doctor blade removes the ink from the surface but  not from the wells. The cylinder comes in contact with the paper, which  draws the ink out of the wells. Because of the various depths of the wells,  a full range of tonal values can be printed; in reproducing illustrations,  gravure comes closest to simulating continuous-tone copy. In colour print�  ing, a separate cylinder is prepared for each colour. See also letterpress  printing; offset printing.</p><p>Gray, Asa (b. Nov. 18, 1810, Sauquoit, N.Y., U.S.�d. Jan. 30, 1888,  Cambridge, Mass.) U.S. botanist. He received a medical degree from  Fairfield Medical School, where he spent his spare time studying plant  specimens. He collaborated with John Torrey (1796-1873) on Flora of  North America (1838^13) and in 1842 joined the faculty at Harvard Uni�  versity, where he would teach until 1873. His donation of his thousands  of books and plant specimens established Harvard�s botany department.  Gray was largely responsible for the unification of the taxonomic knowl�  edge of the North American flora; his most widely used book, commonly  called Gray�s Manual (1848), remains a standard work. He was the chief  early American supporter of the theories of Charles Darwin.</p><p>Gray, Thomas (b. Dec. 26, 1716, London, Eng.�d. July 30, 1771,  Cambridge, Cambridgeshire) British poet. He studied and later settled at  Cambridge, where he wrote poems of wistful melancholy filled with tru�  isms phrased in striking, quotable lines. Though his output was small, he  became the dominant poetic figure in his day. He is remembered espe�  cially for �An Elegy Written in a Country Church Yard� (1751), one of</p><p>the best known of English lyric  poems and the greatest work of the  English �graveyard school.� After its  overwhelming success, his next two  poems met a disappointing response,  and he virtually ceased writing.</p><p>gray fox Grizzled, gray-furred  New World FOX ( Urocyon cinereoar-  genteus) found in forested, rocky,  and brush-covered country from  Canada to northern South America.</p><p>Distinguished by the reddish color  on its neck, ears, and legs, it grows  to a length of about 20-30 in. (50-75  cm), excluding its 12-16-in. (30^10-  cm) tail, and a weight of about 7-13  lbs (3-6 kg). Unlike other foxes, it  commonly climbs trees. Primarily  nocturnal, it takes a variety of foods,  including small birds and mammals,  insects, and fruits.</p><p>gray hound See greyhound</p><p>grayling Any of several game fishes (genus Thymallus), similar to  trout, that are found in cold, clear streams of Eurasia and northern North  America. Graylings are silvery purple and reach a length of about 16 in.  (40 cm). They have relatively large scales, a small mouth with weak teeth,  and a sail-like, brightly coloured dorsal fin. They feed primarily on insects  and spawn in shallow water in the spring. Pollution of streams has reduced  the numbers of this excellent food fish.</p><p>graywacke Vgra-,wak\ or dirty sandstone Sedimentary rock com�  posed of sand-sized grains in a fine-grained clay matrix. The sand-sized  grains frequently include rock fragments of wide-ranging mineralogies  (e.g., pyroxenes, amphiboles, feldspars, and quartz). The clay matrix may  constitute up to 50% of the volume. Of the clay minerals, chlorite and  biotite are most abundant. The matrix tends to bind the grains strongly  and form a relatively hard rock.</p><p>Graz \'grats\ City (pop., 2001: 226,424), capital of Steiermark (Styria)  state, southeastern Austria. The country�s second largest city, it lies on the  Mur River at the foot of the Styrian Alps. It grew from a fortress settle�  ment and received town rights c. ad 1240. It became the centre of Steier�  mark during the Middle Ages and was the residence of the Leopoldine  Habsburgs after 1379. Its fortifications, built in the 15th and 16th centu�  ries, successfully withstood numerous sieges by Hungarians and Turks;  the fortifications were converted into parks in the 19th century. Astrono�  mer Johannes Kepler taught at its university, founded in 1585.

He was commander in chief of Ital�  ian forces in Libya (1930-34), governor of Italian Somaliland (1935-36),  and viceroy of Ethiopia (1936-37). At the outbreak of World War II, he  advanced against Egypt from Libya, was defeated by the British under  Archibald Percival Wavell, and resigned his post in 1941. After the Italian  armistice of 1943, he became defense minister of the German-backed  Italian republic. Sentenced to 19 years� imprisonment in 1950, he was  released the same year. He later became a leader of the Italian neofascist  movement.</p><p>Great Atlantic &amp; Pacific Tea Co. (A&amp;P) Historic U.S. corporation  that originated as a tea importer and distributor before diversifying into  the grocery business. The company had its start in 1859, when the Great  American Tea Co. was founded in New York as a direct-mail operation  to trade in tea from the cargoes of clipper ships. The first retail stores  were incorporated in 1869 under the name Great Atlantic &amp; Pacific Tea  Co. By 1925 it was the largest U.S. grocery chain, and in 1936 A&amp;P  opened its first supermarket. By 1969 it was the largest supermarket chain  in the U.S., but it declined thereafter, and in 1979 a controlling portion  of its stock was bought by German supermarket giant Tengelmann.</p><p>Great Attractor Proposed concentration of mass, equivalent to tens of  thousands of galaxies, that influences the movement of many galaxies,</p><p>Thomas Gray, detail of an oil painting  by John Giles Eccardt; in the National  Portrait Gallery, London</p><p>COURTESY OF THE NATIONAL PORTRAIT GALLERY,  LONDON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>794 i great auk &#x25BA; Great Game</p><p>including the Milky Way Galaxy (see galaxy).

Great auks bred in colonies on rocky islands off North Atlantic coasts; fos�  sil remains have been found as far south as Florida, Spain, and Italy. Their  bodies were about 30 in. (75 cm) long; the wings, used for swimming  underwater, were less than 6 in. (15 cm) long. They stood erect on land and  had a black back and head, a white front, and a large white spot between the  eye and the black bill. Great auks were hunted to extinction for food and  bait. About 80 specimens are preserved in museums. See also auk.</p><p>Great Australian Bight Bay of the Indian Ocean, southern Austra�  lian coast. Its generally accepted boundaries are from Cape Pasley, West�  ern Australia, to Cape Carnot, South Australia�a distance of 720 mi  (1,160 km). The head of the bight abuts on the arid Nullarbor Plain and  is bounded by cliffs 200-400 ft (60-120 m) high. Near Eucla on the  bight�s shores is the Nuytsland Reserve. Lying in the track of the winter  western winds, the bight has a reputation for storms and rough seas.</p><p>Great Awakening Religious revival in British North America from  1720 into the 1740s. It was part of a movement, known as Pietism or Qui�  etism on the European continent and evangelicalism in England, that  swept Western Europe in the late 17th and early 18th century under the  leadership of preachers such as John Wesley. In North America the Great  Awakening was a Protestant evangelical reaction against formalism and  rationalism in religion, and it had a strong Calvinist element. Revivalist  preachers emphasized the need for sinners to fear punishment and to hope  for the unearned gift of grace from God. George Whitefield (1714-1770)  was one of the most popular, preaching to huge crowds throughout the  colonies in 1739�40. Jonathan Edwards also helped inspire the Great  Awakening and was its most important theologian. Among its results were  missions to the Indians and the founding of colleges (including Prince�  ton Univ.). Another revival known as the Second Great Awakening  occurred in New England and Kentucky in the 1790s.</p><p>Great Barrier Reef Extensive complex of coral reefs, shoals, and  islets in the Pacific Ocean, off the northeastern coast of Australia. The  largest deposit of coral in the world, it extends for more than 1,250 mi  (2,000 km) along the coast of Queensland and has an area of some 135,000  sq mi (350,000 sq km). The reef has been formed over millions of years  from the skeletons of a mass of living marine organisms. In addition to  at least 300 species of hard coral, marine life includes anemones, worms,  gastropods, lobsters, crayfish, prawns, crabs, and a variety of fishes.  Encrusting red algae form the purplish red algal rim that is one of the  reef�s characteristic features. A major tourist attraction, nearly all of it is  within Great Barrier Reef National Park; the reef was designated a  UNESCO World Heritage site in 1981.</p><p>Great Basin National Park National preserve, eastern Nevada, U.S.  Made a national park in 1986, the area was previously part of the Hum�  boldt National Forest. It has an area of 121 sq mi (313 sq km) and con�  sists of the southern part of the Snake Mountains, a chain that rises  abruptly from the desert floor to reach a height of 13,063 ft (3,982 m) at  Wheeler Peak. A park attraction is the Lehman Caves, a group of lime�  stone caverns.</p><p>Great Bear Lake Lake, Northwest Territories, Canada. Lying astride  the Arctic Circle, it was visited before 1800 by North West Company trad�  ers and later named for the bears that inhabited its shores. Containing  many small islands, Great Bear Lake is roughly 200 mi (320 km) long  and 25-110 mi (40-175 km) wide and has a maximum depth of 1,356 ft  (413 m). It is the largest lake entirely within Canada and the fourth larg�  est in North America. The lake�s waters abound with fish, including the  speckled trout.</p><p>Great Britain or Britain Island, western Europe. It is the largest island  in Europe, comprising England, Scotland, and Wales and covering 88,787  sq mi (229,957 sq km). With Northern Ireland, it constitutes the United  Kingdom of Great Britain and Northern Ireland. Less formally, the names  Great Britain and Britain are used to refer to the entire United Kingdom.</p><p>Great Dane Breed of working dog developed at least 400 years ago in  Germany, where it was used for boar hunting. Tallest of the working  breeds, it stands 28-32 in. (71-81 cm) tall and weighs 120-150 lbs (54-68  kg). It has a massive, square-jawed head and elegant body lines. Its short  coat is black, golden brown, brindle, blue-gray, or white with black  patches. It is typically swift and alert and is noted for courage, friendli�  ness, and dependability. There is no known reason to associate Denmark  with the breed.</p><p>Great Depression Longest and most severe economic depression ever  experienced by the Western world. It began in the U.S. soon after the New  York Stock Market Crash of 1929 and lasted until about 1939. By late  1932 stock values had dropped to about 20% of their previous value, and  by 1933 11,000 of the U.S.�s 25,000 banks had failed. These and other  conditions, worsened by monetary policy mistakes and adherence to the  gold standard, led to much-reduced levels of demand and hence of pro�  duction, resulting in high unemployment (by 1932, 25-30%). Since the  U.S. was the major creditor and financier of postwar Europe, the U.S.  financial breakdown precipitated economic failures around the world,  especially in Germany and Britain. Isolationism spread as nations sought  to protect domestic production by imposing tariffs and quotas, ultimately  reducing the value of international trade by more than half by 1932. The  Great Depression contributed to political upheaval. It led to the election  of U.S. Pres. Franklin Roosevelt, who introduced major changes in the  structure of the U.S. economy through his New Deal. The Depression also  advanced Adolf Hitler�s rise to power in Germany in 1933 and fomented  political extremism in other countries. Before the Great Depression, gov�  ernments relied on impersonal market forces to achieve economic cor�  rection; afterward, government action came to assume a principal role in  ensuring economic stability.</p><p>Great Dismal Swamp See Dismal Swamp</p><p>Great Dividing Range Main watershed of eastern Australia. It com�  prises a series of plateaus and mountain ranges roughly paralleling the  coasts of Queensland, New South Wales, and Victoria, Austl. Beginning  in the north on the Cape York Peninsula, Queen., the range heads south  to become the Australian Alps near the New South Wales-Victoria border.  Bending west in Victoria, the range ends in the Grampians, while a south�  ern spur emerges from the Bass Strait to form the central uplands of Tas�  mania. The range stretches for 2,300 mi (3,700 km). First traversed in 1813  by Europeans moving into the Australian Outback, the region is now  important for agriculture, lumbering, and mining, and national parks  attract tourists.</p><p>Great Fear (1789) In the French Revolution, a period of panic and riot by  peasants and others amid rumors of an �aristocratic conspiracy� by the king  and the privileged to overthrow the Third Estate. The gathering of troops  around Paris provoked insurrection, and on July 14 the Parisian rabble  seized the Bastille. In the provinces the peasants rose against their lords,  attacking chateaux and destroying feudal documents. To check the peas�  ants, the National Constituent Assembly decreed the abolition of the feudal  regime and introduced the Declaration of the Rights of Man and of the Citi�  zen.</p><p>Great Fire of London (September 2-5, 1666) Worst fire in London�s  history. It destroyed a large part of the city, including most of the civic  buildings, St. Paul's Cathedral, 87 parish churches, and about 13,000  houses. It began accidentally at the house of the king�s baker in Pudding  Lane near London Bridge, and a violent east wind encouraged the flames.  On the fourth day houses were blown up by gunpowder to master the fire.  The Thames River swarmed with vessels filled with people trying to save  their goods, and some fled to the hills of Hampstead and Highgate, but  most of the houseless Londoners settled in Moorfields.</p><p>Great Fish River River, southeastern Eastern Cape province, South  Africa. Flowing southeast for much of its 400-mi (644-km) run, it joins  the Koonap River before entering the Indian Ocean southeast of Graha-  mstown.

Comprising  Lakes Superior, Michigan, Huron, Erie, and Ontario, it forms a natural  boundary between the U.S. and Canada. The Great Lakes cover an area  of about 94,850 sq mi (245,660 sq km) and constitute the largest fresh�  water surface in the world. Connected to form a single waterway that dis�  charges down the St. Lawrence River into the Atlantic Ocean, with the St.  Lawrence Seaway they form a shipping lane more than 2,000 mi (3,200  km) long that carries oceangoing traffic as far west as Duluth, Minn. Large  quantities of iron ore, coal, grain, and manufactured goods are moved  between lake ports and shipped overseas. While commercial fishing was  once a major industry on the lakes, pollution and other factors led to its  collapse; recovery has been slow and partial. The lakes are used for many  recreational activities, including boating and sailing.</p><p>Great Lakes Group of large lakes located chiefly in the Great Rift Val�  ley, eastern central Africa.

Mao Zedong  hoped to develop labor-intensive methods of industrialization that would  emphasize manpower rather than the gradual purchase of heavy machinery,  thereby putting to use China�s dense population and obviating the need to  accumulate capital. Rather than large new factories, he proposed develop�  ing backyard steel furnaces in every village. Rural people were organized  into communes where agricultural and political decisions emphasized  ideological purity rather than expertise. The program was implemented so  hastily and zealously that many errors occurred; these were exacerbated by  a series of natural disasters and the withdrawal of Soviet technical person�  nel. China�s agriculture was so disrupted that about 20 million people died  of starvation from 1958 to 1962. By early 1960 the government began to  repeal the Great Leap Forward; private plots were returned to peasants and  expertise began to be emphasized again.</p><p>Great Mosque See Masjid-i-Jami</p><p>Great Mosque of Esfahan Persian Masjed-e Jami'</p><p>Vmas-jid-i-'ja-meX Complex of buildings, chiefly of the Seljuq period (see  SeuOq dynasty), in Esfahan, Iran.

The  brick dome of the main sanctuary (c. 1070-75) is supported by heavy  piers. The smaller domed chamber (1088) is known for its beauty of pro�  portion; its dome, resting on a series of arches, is a structural masterpiece.  The dome and the four -eyvan plan became standard for Seljuq mosques.</p><p>Great Mother of the Gods or Cybele Vsi-b3-le\ Deity of the  ancient Mediterranean world. Her cult originated in Phrygia in Asia Minor  and spread to the Greek world, where she was identified with Rhea. It  reached Rome by the 3rd century bc and became a major cult during the  empire. Known by a variety of local names, Cybele was venerated as the  universal mother of gods, humans, and animals. Her lover was the fertil�  ity god Attis. Her priests, the Galli, castrated themselves when they  entered her service, and on her festival day they spattered their blood on  her altar and her sacred pine tree.

Hill bought a Minnesota railroad, the St. Paul and Pacific Rail�</p><p>road, in 1878, and extended it north  to the Canadian border and west to  the Pacific coast, encouraging thou�  sands of homesteaders to settle along  its tracks. Together with J. P. Morgan  of the Northern Pacific Railway Co.,  Hill bought control of the Chicago,  Burlington &amp; Quincy Railroad in  1901 and set up a holding company to  control the three railroads. In 1904  the U.S. Supreme Court declared the  company in violation of antitrust  laws and ordered it dissolved, but the  Burlington continued under control  of the Great Northern and the North�  ern Pacific.

As early as 1625,  40,000 Londoners had died of the  plague, but this was the worst and the  last of the epidemics. Most of the  devastation was in the city�s out�  skirts, in areas where the poor were  densely crowded. The disease spread  throughout the country, but from  1667 only sporadic cases appeared  until 1679. The plague�s decline was  attributed to various causes, including the Great Fire of London. Daniel  Defoe�s Journal of the Plague Year (1722) provides a valuable picture of  the time.</p><p>Great Plains Continental slope of central North America. It stretches  from the Rio Grande at the U.S.-Mexico border in the south to the Mac�  kenzie River delta along the Arctic Ocean in the north and from the Inte�  rior Lowlands and the Canadian Shield in the east to the Rocky Mountains  in the west. The plains embrace parts of 10 U.S. states and 4 Canadian  provinces, covering an area of about 1,125,000 sq mi (2,900,000 sq km).  A high plateau of semiarid grassland, these prairie regions in both the U.S.  and Canada produce the major proportion of wheat grown in each coun�  try and are also important cattle- and sheep-herding areas.

One of the highest of the Alpine frontier passes, at 8,100 ft (2,469 m) it  lies on the Italian-Swiss border east of the Mont Blanc group and con�  nects Martigny-Ville, Switz., with Aosta, Italy. Historically the most  important trans-Alpine route, it was often used by pilgrims to Rome and  later by medieval armies. In 1800 it was crossed by Napoleon and his  40,000 troops on their way to northern Italy. A famous hospice on the  pass, founded by St. Bernard of Menthon in the 11th century, is still kept  by Augustinian monks who, with their St. Bernard dogs, provide services  to travelers. The old road, open only five months a year, has been partly  superseded by a tunnel beneath the pass, which allows year-round travel.</p><p>Great Salt Lake Lake, northern Utah, U.S. It is the largest inland body  of salt water in the Western Hemisphere and one of the most saline in the  world. It fluctuates greatly in size, depending on rates of evaporation and  the flow of the rivers into it. Its surface area has varied from about 2,400  sq mi (6,200 sq km) at its highest levels in 1873 and the mid 1980s to  about 950 sq mi (2,460 sq km) at its low level in 1963. At times of median  water level, it is generally less than 15 ft (4.5 m) deep. Surrounded by  stretches of sand, salt land, and marsh, the lake remains isolated, though  in recent years it has become important as a source of minerals, as a beach  and water-sports attraction, and as a wildlife preserve.</p><p>Great Sand Dunes National Park and Preserve Natural area,  south-central Colorado, U.S. It lies at the eastern edge of the San Luis  Valley along the western base of the Sangre de Cristo Mountains.

One of the largest  building-construction projects ever carried out, it runs (with all its  branches) about 4,500 mi (7,300 km) east to west from the Bo Hai (Gulf  of Chihli) to a point deep in Central Asia. Large parts of the fortification  date from the 7th to the 4th century bc. In the 3rd century bc the emperor  Shihuangdi connected existing defensive walls into a single system forti�  fied by watchtowers. These served both to guard the rampart and to com�  municate with the capital, Xianyang (near modern Xi'an) by signal�  smoke by day and fire by night. Originally constructed partly of masonry  and earth, it was faced with brick in its eastern portion. It was rebuilt in  later times, especially in the 15th and 16th centuries. The basic wall is  about 23-26 ft (7-8 m) high; at intervals towers rise above it to varying  heights. It was designated a UNESCO World Heritage site in 1987.</p><p>great white shark or white shark Large, aggressive shark ( Car-  charodon carcharias, family Lamnidae), considered the species most dan�  gerous to humans.

The  great white is heavy-bodied and has a crescent-shaped tail and large, saw-  edged, triangular teeth. It can reach a length of more than 20 ft (6 m) and  is generally gray, bluish, or brownish, with the colour shading suddenly  into a whitish belly. Though it is widely feared, only a few hundred  humans are known to have ever been killed by the great white shark.</p><p>Great Zimbabwe Extensive stone ruins in southeastern Zimbabwe.

Domenikos Theotokopoulos (b. 1541, Candia,  Crete�d. April 7, 1614, Toledo, Spain) Cretan-born Spanish painter, the  first great master of Spanish painting. Documentation on his early life is  limited, but it is known that he was in Venice c. 1566-70 and may have  studied in Titian�s workshop. In 1572 he was a member of the guild of St.  Luke in Rome. His first commission in Spain (1577) was for altarpieces  for the church of Santo Domingo el Antiguo in Toledo (1577-79); the  paintings for the high altar show the influence of Titian and Michelangelo.  In these works he developed his signature style: he chose a method of  space elimination that is common to middle and late 16th-century Italian  painters known as Mannerists. The elogonated figures in these works were  also characteristic of his oeuvre. El Greco�s Mannerist method of com�  position is nowhere more clearly expressed than in his masterpiece. The  Burial of the Count de Orgaz (1586�88), where all of the action takes  place in the frontal plane. From 1590 until his death his output was pro�  digious. His major commissions included the complete altar composition  for the Hospital de la Caridad at Illescas (1603-05), for which he also  worked as architect and sculptor. He excelled as a portraitist. His work�  shop produced many replicas of his works, but his style was so individual  that his only followers were his son and a few forgotten imitators.</p><p>Greco-Persian Wars See Persian Wars</p><p>Greco-Roman wrestling Style of wrestling that prohibits the legs  from being used to obtain a fall and in which no holds may be taken below  the waist.

It eventually  came to be favoured by most other countries and was, until the accep�  tance of freestyle wrestling in the late 20th century, the style practiced  exclusively in Olympic and international amateur competition.</p><p>Greco-Turkish Wars (1897, 1921-22) Two military conflicts between  the Greeks and the Turks. The first, or Thirty Days� War, took place after  an 1896 rebellion on Turkish-ruled Crete between Christian residents and  their Muslim rulers. Greek troops occupied the island in 1897. The Euro�  pean powers imposed a blockade to prevent assistance to the island.  Unable to reach Crete, the Greeks sent a force to attack the Turks in Thes�  saly, but it was overwhelmed by the superior Turkish army. Though a  peace treaty forced the Greeks to withdraw, Turkish troops also left Crete,  which had been made an international protectorate and was later (1913)  ceded to Greece. The second war occurred after World War I, when the  Greeks attempted to claim territories assigned to them by the Treaty of  Sevres (1920). In 1921 the Greek army launched an offensive in Anatolia  against nationalist Turks who would not recognize the treaty. The Greek  forces were driven out by Mustafa Kemal Ataturk, and the Treaty of Lau�  sanne (1923) returned the disputed territories to Turkey.</p><p>Greece officially Hellenic Republic Country, Balkan Peninsula, south�  eastern Europe. Area: 50,949 sq mi (131,957 sq km). Population (2005  est.): 11,088,000. Capital: Athens. The people are predominantly Greek.  Language: Greek (official). Religion: Christianity (predominantly Eastern  Orthodox [official]). Currency: euro. The land, with its 2,000-odd islands  and extensive coastline, is intimately linked with the sea. About one-fifth  of this mountainous country consists of lowland, much of this as coastal  plains along the Aegean or as mountain valleys and small plains near river  mouths. The interior is dominated by the Pindus Mountains, which extend  from Albania on Greece�s northwestern border into the Peloponnese.  Mount Olympus is the country�s highest peak. Among the Greek islands</p><p>Slavonian, or horned, grebe (Podiceps  auritus)</p><p>INGMAR HOLMASEN</p><p>are the Aegean and Ionian groups and  Crete. The climate is Mediterranean.  Greece has an advanced developing  economy characterized mainly by private  enterprise and based on agriculture,  manufacturing, and tourism. It is a multiparty republic with one legisla�  tive house; the chief of state is the president, and the head of government  is the prime minister. The earliest urban society in Greece was the palace-  centred Minoan civilization, which reached its height on Crete c. 2000 bc.  It was succeeded by the mainland Mycenaean civilization, which arose c.  1600 bc following a wave of Indo-European invasions. About 1200 bc a  second wave of invasions destroyed the Bronze Age cultures, and a Dark  Age followed, known mostly through the epics of Homer. At the end of  this time, Classical Greece began to emerge (c. 750 bc) as a collection of  independent city-states, including Sparta in the Peloponnese and Athens  in Attica. The civilization reached its zenith after repelling the Persians  at the beginning of the 5th century bc (see Persian Wars) and began to  decline after the civil strife of the Peloponnesian War at the century�s end.  In 338 bc the Greek city-states were taken over by Philip II of Macedon,  and Greek culture was spread by Philip�s son Alexander the Great through�  out his empire. The Romans, themselves heavily influenced by Greek cul�  ture, conquered the city-states in the 2nd century bc. After the fall of  Rome, Greece remained part of the Byzantine Empire until the mid-15th  century, when it became part of the expanding Ottoman Empire; it gained  its independence in 1832. It was occupied by Nazi Germany during World  War II. Civil war followed and lasted until 1949, when communist forces  were defeated. In 1952 Greece joined NATO. A military junta ruled the  country from 1967 to 1974, when democracy was restored and a refer�  endum declared an end to the Greek monarchy. In 1981 Greece joined the  European Community (see European Union), the first eastern European  country to do so. Upheavals in the Balkans in the 1990s strained Greece�s  relations with some neighbouring states, including the former Yugoslav  entity that became the Republic of Macedonia. Greece revised its consti�  tution in 2001.</p><p>Greek alphabet Writing system developed in Greece c. 1000 bc, the  direct or indirect ancestor of all modem European alphabets. Derived from  the North Semitic alphabet via that of the Phoenicians, it modified an all�  consonant alphabet to represent vowels. Letters for sounds not found in  Greek became the Greek letters alpha, epsilon, iota, omicron, and upsi-  lon, representing the vowels a, e, i, o, and u. This greatly increased the  accuracy and legibility of the new system. While the Chalcidian version  of the Greek alphabet probably gave rise to the Etruscan alphabet and  thus indirectly to the Latin alphabet, in 403 bc Athens officially adopted the  Ionic version. This became the classical Greek alphabet, which had 24</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>798 i Greek Civil War &#x25BA; Greek religion</p><p>letters, all capitals�ideal for monuments; various scripts better suited to  handwriting were later derived from it.</p><p>Greek Alphabet</p><p>Letters</p><p>English</p><p>sound</p><p>Name</p><p>Letters</p><p>English</p><p>sound</p><p>Name</p><p>A a</p><p>a</p><p>alpha</p><p>Nv</p><p>n</p><p>nu</p><p>B|3</p><p>b</p><p>beta</p><p>Hi;</p><p>X</p><p>xi</p><p>r r</p><p>9</p><p>gamma</p><p>Oo</p><p>o</p><p>omicron</p><p>A 5</p><p>d</p><p>delta</p><p>n n</p></section><section><p>P</p><p>P'</p><p>E �</p><p>e</p><p>epsilon</p><p>Pp</p><p>rh, r</p><p>rho</p><p>ZC</p><p>z</p><p>zeta</p><p>2 a,q</p><p>s</p><p>sigma</p><p>H r|</p><p>e</p><p>eta</p><p>Tx</p><p>t</p><p>tau</p><p>0 0</p><p>th</p><p>theta</p><p>Yu</p><p>y. u</p><p>upsilon</p><p>I V</p><p>�</p><p>iota</p><p>&lt;S cp</p><p>ph</p><p>phi</p><p>K K</p><p>k</p><p>kappa</p><p>Xx</p><p>kh</p><p>chi</p><p>AX</p><p>i</p><p>lambda</p><p>'By</p><p>ps</p><p>psi</p><p>Mu</p><p>m</p><p>mu</p><p>Q co</p><p>5</p><p>omega</p><p>Greek Civil War (1944-45, 1946-49). Two-stage conflict during  which Greek communists unsuccessfully tried to gain control of Greece.  The two principal Greek guerrilla forces that had resisted Nazi Germa�  ny�s occupation�the communist-controlled National Liberation Front-  National Popular Liberation Army (EAM-ELAS) and the Greek  Democratic National Army (EDES)�came into conflict after EAM-  ELAS set up a provisional government that rejected the Greek king and  his government-in-exile. When Germany withdrew from Greece in 1944,  the communists and royalist guerrillas were brought together by the Brit�  ish in an uneasy coalition. Because the communist guerrillas refused to  disband their forces, a bitter civil war broke out in late 1944 that was put  down by British forces. After elections that the communists did not par�  ticipate in, the Greek king was restored to his throne. In 1946 a full-scale  guerrilla war was reopened by the communists. The U.S. government took  over the defense of Greece, creating the Truman Doctrine as justification.  After fierce skirmishes in the mountains, in 1949 the communists  announced the end of open hostilities. An estimated 50,000 Greeks died  in the conflict, which left a legacy of bitterness.</p><p>Greek fire Any of several flammable mixtures used in ancient and  medieval warfare, particularly a petroleum-based mixture invented by the  Byzantine Greeks in the 7th century. Flammable materials such as pitch  and sulfur had been used in war since ancient times, but true Greek fire  was especially deadly. Thrown in pots or discharged from tubes, it appar�  ently caught fire spontaneously, and water could not put it out. Greek fire  launched from tubes mounted on ship prows wrought havoc on the Arab  fleet attacking Constantinople in 673. Its effectiveness was a prime rea�  son for the long survival of the Byzantine Empire. The recipe was so  secret that its precise composition remains unknown.</p><p>Greek Independence, War of (1821-32) Rebellion of Greeks  within the Ottoman empire. The revolt began under the leadership of Alex�  andras Ypsilanti (1792-1828). He was soon defeated, but in the meantime  other rebels in Greece and on several islands gained control of the  Peloponnese and declared Greek independence (1822). Three times the  Turks attempted invasions. Internal rivalries prevented the Greeks from  extending their control and consolidating their position. With Egyptian  reinforcements, the Turks successfully invaded the Peloponnese and cap�  tured several cities, but the intervention of the European powers saved the</p><p>Greek cause. A settlement was finally reached at an 1830 London con�  ference, declaring Greece an independent monarchical state.</p><p>Greek language Indo-European language spoken mostly in Greece.  Its history can be divided into four phases: Ancient Greek, Koine, Byz�  antine Greek, and Modern Greek. Ancient Greek is subdivided into Myce�  naean Greek (14th�13th centuries bc) and Archaic and Classical Greek  (8th-4th centuries bc). The language of the latter periods had numerous  dialects (e.g., Ionic, Attic). The second phase, Koine (Hellenistic Greek),  arose during the reign of Alexander the Great in the 4th century bc. A  common language with simplified grammar, it spread throughout the Hel-  lenized world. Purists who rejected Koine as a corruption of Attic Greek  successfully advocated adoption of the Classical language for all writing.  Thus, the written form, Byzantine Greek (5th�15th centuries ad), stayed  rooted in the Attic tradition while the spoken language continued to  develop. Modern Greek, dating from the 15th century, has many local  dialects. Standard Modern Greek, Greece�s official written and spoken  language, is largely based on a form called Demotic (used in popular  speech) but includes elements of Katharevusa, the written language for�  merly used in government and public life.</p><p>Greek law Legal systems of the ancient Greeks. Each city-state admin�  istered its own laws, many of which were laid down in written statutes. The  harsh law code of Draco and the more humane one of Solon are two of the  most famous. Unlike Roman law, Greek law produced little analytical juris�  prudence, though the philosophers examined abstract concepts of justice.  Those who sat in judgment based their verdicts less on notions of equity  than on the statutes� literal meaning. Both private and criminal procedures  began with the summoning of the defendant to the magistrate and the filing  of a written complaint. A type of arbitration was available in civil suits.  Enforcement of a judgment was generally left to the plaintiff.</p><p>Greek mythology Oral and literary traditions of the ancient Greeks  concerning their gods and heroes and the nature and history of the cos�  mos. The Greek myths and legends are known today primarily from Greek  literature, including such classic works as Homer�s Iliad and Odyssey,  Hesiod�s Works and Days and Theogony, Ovid�s Metamorphoses, and the  dramas of Aeschylus, Sophocles, and Euripides. The myths deal with the  creation of the gods and the world, the struggle among the gods for  supremacy and the triumph of Zeus, the love affairs and quarrels of the  gods, and the effects of their adventures and powers on the mortal world,  including their link with natural phenomena such as thunderstorms or the  seasons and their connection with cultic sites or rituals. Among the great  stories of Greek mythology and legend are those of the Trojan War, the  voyage of Odysseus, Jason�s search for the Golden Fleece, the exploits of  Heracles, the adventures of Theseus, and the tragedy of Oedipus. See also  Greek religion.</p><p>Greek Orthodox Church Independent Eastern Orthodox church of  Greece. The term is sometimes used erroneously for Eastern Orthodoxy  in general. It remained under the patriarch of Constantinople until 1833,  when it became independent. It is governed by 67 metropolitan bishops,  presided over by an archbishop.</p><p>Greek pottery Pottery made in ancient Greece. Its painted decoration  has become the primary source of information about the development of  Greek pictorial art. It was made in a variety of sizes and shapes, accord�  ing to its intended use; large vessels were used for storage and transpor�  tation of liquids (wine, olive oil, water), smaller pots for perfumes and  unguents. The earliest style, known as the Geometric style (c. 1000-700  bc), features geometric patterns and, eventually, narrative scenes with  stylized figures. From the late 8th to the early 7th century bc, a growing  Eastern influence resulted in the �Orientalizing� of motifs (e.g., sphinx,  griffin), notably in pieces made in Corinth (c. 700 bc), where the painters  developed black-figure pottery. Athenians adopted the black-figure style  and from 600 bc on became the dominant manufacturers of Greek pot�  tery. They invented red-figure pottery c. 530 bc. By the 4th century bc the  figured decoration of pottery had declined, and by the end of the century  it had died out in Athens.</p><p>Greek religion Beliefs, rituals, and mythology of the ancient Greeks.  Though the worship of the sky god Zeus began as early as the 2nd mil�  lennium bc, Greek religion in the established sense began c. 750 bc and  lasted for over a thousand years, extending its influence throughout the  Mediterranean world and beyond. The Greeks had numerous gods who  controlled various natural or social forces (e.g., Poseidon the sea, Demeter  the harvest, Hera marriage). Different deities were worshiped in different</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Greek Revival &#x25BA; Green Mountains I 799</p><p>localities, but Homer�s epics helped create a unified religion, in which the  major gods were believed to live on Mount Olympus under the rule of Zeus.  The Greeks also worshiped various gods of the countryside: Pan, nymphs,  naiads, dryads, Nereids, and satyrs (see satyr and silenus), along with the  Furies and the Fates. Heroes from the past, such as Heracles and Asclepius,  were also venerated. Animal sacrifices were of great importance, usually  made at a temple on the altar of the god. Other cultic activities included  prayers, libations, processions, athletic contests, and divination, particu�  larly through oracles and birds. Great religious festivals included the City  Dionysia at Athens and the festival of Zeus in the western Peloponnese  that included the Olympic Games. Death was seen as a hateful state; the  dead lived in the realm of Hades, and only heroes enjoyed Elysium. Great  wrongdoers suffered in Tartarus. Mystery religions emerged to satisfy the  desire for personal guidance, salvation, and immortality. Greek religion  faded with the rise of Christianity and lost its last great advocate with the  death of Julian in ad 363.

The new varieties require large amounts of chemi�  cal fertilizers and pesticides to produce their high yields, raising concerns  about cost and potentially harmful environmental effects.

To  finance the American Civil War the U.S. government issued paper money  not backed by gold and printed in green ink, called greenbacks. After the  war fiscal conservatives called for an end to greenbacks, but farmers and  others who wanted to maintain high prices opposed the move. In 1868 the  Democrats endorsed a plan to redeem some war bonds with new green�  backs. The depression after the panic of 1873 intensified the demand for  more greenbacks or unlimited silver coinage. After passage of the  Resumption Act (1875), which provided for redemption of greenbacks in  gold, the newly formed Greenback-Labor Party sought its repeal. In 1878  it elected 14 members of Congress, but support waned after 1884. See  also Free Silver Movement, Popuust movement.</p><p>Greenberg, Clement (b. Jan. 16, 1909, New York, N.Y., U.S.�d.

He eschewed more  orthodox methods of historical linguistics for the approach he termed  �mass� or �multilateral� comparison, which involved looking for phonetic  resemblances among words in many languages simultaneously. His 1963  classification of African languages into four families (Afroasiatic, Niger-  Congo, Nilo-Saharan, and Khoisan) was widely accepted. However, his  1987 classification of all American Indian languages into just two families,  Amerind and Na-Dene (see Athabaskan languages) provoked a rancorous  denunciation by specialists, who faulted both his data and his method.</p><p>Greene, Charles Sumner and Henry Mather (respectively b.

Visible light from the Sun heats the Earth�s surface. Part  of this energy is radiated back into the atmosphere in the form of infrared  radiation, much of which is absorbed by molecules of carbon dioxide and  water vapour in the atmosphere and reradiated toward the surface as more  heat. (Despite the name, the greenhouse effect is different from the warm�  ing in a greenhouse, where panes of glass allow the passage of visible  light but hold heat inside the building by trapping warmed air.) The  absorption of infrared radiation causes the Earth�s surface and lower  atmosphere to warm more than they otherwise would, making the Earth�s  surface habitable. An increase in atmospheric carbon dioxide caused by  widespread combustion of fossil fuels may intensify the greenhouse effect  and cause long-term climatic changes. Likewise, an increase in atmo�  spheric concentrations of other trace greenhouse gases such as chloro-  fluorocarbons, nitrous oxide, and methane resulting from human activities  may also intensify the greenhouse effect. From the beginning of the Indus�  trial Revolution through the end of the 20th century, the amount of car�  bon dioxide in the atmosphere increased 30% and the amount of methane  more than doubled. It is also estimated that the U.S. is responsible for  about one-fifth of all human-produced greenhouse-gas emissions.

The world�s largest island (excluding Australia), it covers  836,330 sq mi (2,166,086 sq km). Population (2005 est.): 57,100. Capital:  Nuuk. Two-thirds of the island lies within the Arctic Circle. It is dominated  by the massive Greenland Ice Sheet. Fishing is central to the economy; there  are also commercial mineral deposits, including a large gold deposit dis�  covered in 1989, as well as offshore oil exploration. About four-fifths of the  population are native Greenlanders, principally of Inuit (see Eskimo)  descent, residing in coastal areas. The Inuit probably crossed to northwest�  ern Greenland from mainland North America, along the islands of the  Canadian Arctic, from 4000 bc to ad 1000. The Norwegian Erik the Red vis�  ited Greenland in 982; his son, Leif Eriksson, introduced Christianity in the  11th century. Greenland came under joint Danish-Norwegian rule in the  late 14th century. The original Norse settlements became extinct in the 15th  century, but Greenland was recolonized by Denmark in 1721. In 1776 Den�  mark closed the Greenland coast to foreign trade; it was not reopened until  1950. Greenland became part of the Kingdom of Denmark in 1953. Home  rule was established in 1979. At the beginning of the 21st century, the  movement for full independence began to gain support, as did the belief  among many scientists that global warming was responsible for the accel�  erated melting of the ice sheet.

The following year, the organization officially formed  itself as a federal party. It called for the dismantling of the Warsaw Pact and  NATO and the demilitarization of Europe. It first won representation in the  Bundestag in 1983. It experienced almost constant ideological tensions  between its left wing and a more pragmatic faction. In 1990 the eastern  German Greens joined with Alliance 90, a coalition of various grassroots  organizations, and won representation in the German national legislature,  though the western German Greens failed to win representation.

The minerals commonly found in such rocks include quartz,  orthoclase, muscovite, chlorite, serpentine, talc, and epidote; carbonate  minerals and amphibole (actinolite) may also be present.</p><p>Greenspan, Alan (b. March 6, 1926, New York, N.Y., U.S.) U.S.  economist and chairman of the board of the Federal Reserve System from  August 1987 to January 2006. He received a doctorate from New York  University in 1977. Having become a private economic consultant,  Greenspan served as chairman of the president�s Council of Economic  Advisers under Pres. Gerald Ford. From 1981 to 1983 he chaired the  bipartisan National Commission on Social Security Reform. In 1987 Pres.  Ronald Reagan appointed him chairman of the Federal Reserve Board, a  position he continued to hold under Presidents George Bush, Bill Clin�  ton, and George W. Bush. As Federal Reserve chairman, he became  known for his decisive use of monetary policy in steering the economy  between the hazards of inflation and recession.</p><p>Greenwich Vgre-nich, 'gri-nij\ Outer borough (pop., 2001: 214,403),  Greater London, on the southern bank of the River Thames. The meridian  that passes through the borough serves as the basis for standard time as  well as for reckonings of longitude throughout the world. Greenwich Park  was enclosed by the duke of Gloucester in 1433; it was the site of the  Royal Observatory (founded 1675). Other historic buildings include the  Queen�s House, now part of the National Maritime Museum, and the  Royal Naval College (1873-1998). These and other historic places were  designated a UNESCO World Heritage site in 1997. The Millennium  Dome, constructed in the 1990s, was used for millennial celebrations to  usher in the year 2000.</p><p>Greenwich Mean Time (GMT) Former name for mean solar time  of the longitude (0�) of the former Royal Observatory at Greenwich,  England, or Greenwich meridian. GMT was used to avoid potentially  confusing references to local time systems (zones). In accord with tradi�  tion, 0000 GMT (denoting the start of a solar day) occurred at noon. In  1925 the numbering system for GMT was changed so that the day (like  the civil day) began at midnight. Some confusion resulted, and in 1928  the International Astronomical Union changed the designation of the stan�  dard time of the zero meridian to Universal Time, which remains in gen�  eral use. The term GMT is still used for some purposes (including  navigation) in English-speaking countries.</p><p>Greenwich Village Residential section, Lower Manhattan, New York,  New York, U.S. A village settlement during colonial times, it became in  successive stages an exclusive residential area, a tenement district, and,  after 1910, a rendezvous for writers, artists, students, bohemians, and  intellectuals. The quaintness of its old townhouses led to rising rents in  the 1980s and �90s. Washington Square, in its centre, is dominated by  Washington Arch and New York University.</p><p>Gregoire \gra-'gwar\, Henri (b. Dec. 4, 1750, Veho, Lorraine,  France�d. May 20, 1831, Paris) French prelate who defended of the  Constitutional Church in the French Revolution as well as the rights of  Jews and blacks. Elected to the National Assembly (1789), he worked to  unite the clergy with the Third Estate. Initially opposed to the Civil Con�  stitution of the Clergy, he later became the Constitutional bishop of Loir-  et-Cher (1790). In the de-Christianizing campaign of 1793-94, he  continued to wear clerical dress and profess his faith openly. After the  collapse of the Jacobin regime, he was a leader in restoring freedom of  worship and reorganizing the church. He opposed Napoleon�s regime and  the Concordat of 1801 that ended the Constitutional Church. He sup�  ported the independent republic of Haiti created in 1804. He served as  adviser to the Jewish council convened by Napoleon in 1807.</p><p>Gregorian calendar Solar dating system now in general use. It was  proclaimed in 1582 by Pope Gregory XIII as a reform of the Julian cal�</p><p>endar. By the Julian reckoning, the solar year comprised 36514 days. The  addition of a �leap day� every four years was intended to maintain cor�  respondence between the calendar and the seasons; however, a slight  inaccuracy in the measurement of the solar year caused the calendar dates  of the seasons to regress almost one day per century. By Pope Gregory�s  time, the Julian calendar was 10 days out of sync with the seasons; in  1582, to bring the vernal equinox (and thus Easter) back to its proper date,  10 days were dropped (October 5 became October 15). Most of Catholic  Europe soon adopted the new calendar; Great Britain and its colonies  (1752) and Russia (1918) followed much later. The Gregorian calendar  differs from the Julian only in that no century year is a leap year unless  it is exactly divisible by 400 (e.g., 1600, 2000). A further refinement, the  designation of years evenly divisible by 4,000 as common (not leap) years,  will keep the calendar accurate to within one day in 20,000 years.</p><p>Gregorian chant Liturgical music of the Roman Catholic church con�  sisting of unaccompanied melody sung in unison to Latin words. It is  named for Pope Gregory I, who may have contributed to its collection  and codification and who was traditionally represented as having received  all the melodies directly from the Holy Spirit. Of the five bodies of medi�  eval Latin liturgical music, it is the dominant repertoire, and the name is  often used broadly to include them all. Gregorian chant apparently derived  principally from Jewish cantillation, with other elements entering from  the Eastern Church (see Byzantine chant) and elsewhere. Chant has tradi�  tionally been performed at the mass and the canonical hours (the eight  prayer services traditionally held daily in monasteries). Its texts come pri�  marily from the biblical psalms, metrical hymns, and texts specific to the  mass and the hours. The melodies are classified as belonging to one or  another of the eight church modes. Chant rhythm is not strictly metrical,  and its notation does not indicate rhythm. Since the Second Vatican Coun�  cil, the performance of chant has diminished greatly. See also cantus fir-  MUS.</p><p>Gregory I, Saint known as Gregory the Great (b. c. 540,  Rome�d. March 12, 604, Rome) Pope (590-604) and doctor of the  church. A Roman patrician, by age 32 he had attained the office of urban  prefect. He then felt called to the religious life. He built several monas�  teries and served as a papal representative before being elected pope in  590, to which he only reluctantly assented. He became the architect of the  medieval papacy, seeking, among other things, to curb corruption by cen�  tralizing the papal administration. In 598 he won temporary peace with  the Lombards, and he allowed the Byzantine usurper Phocas to make per�  manent peace with them in 602. Eager to convert pagan peoples, Gregory  sent Augustine of Canterbury on a mission to England (596). Under Gre�  gory, Gothic Arian Spain see Arianism) became reconciled with Rome. He  laid the basis for the Papal States. He was a strong opponent of slavery,  and he extended tolerance to Jews. He wrote the Pastoral Rule, a guide  for church government, and other works. His extensive recodification of  the liturgy and chant led to his name being given to Gregorian chant. He  is remembered as one of the greatest of all the medieval popes.</p><p>Gregory VII, Saint orig. Hildebrand (b. 1020, near Soana, Papal  States�d. May 25, 1085, Salerno, Principality of Salerno; canonized  1606; feast day May 25) Pope (1073-85). Educated in a monastery in  Rome where his uncle was abbot, he rose to become a cardinal and arch�  deacon of Rome and was finally chosen pope in 1073. One of the great  medieval reformers, Gregory attacked simony and clerical marriage and  insisted that his papal legates had authority over local bishops. He is  remembered chiefly for his conflict with Emperor Henry IV in the Inves�  titure Controversy. Gregory�s excommunication of the emperor gave rise  to a bitter quarrel that ended when Henry begged for forgiveness in a  memorable scene at Canossa, Italy, in 1077. A renewed quarrel led Gre�  gory to excommunicate the emperor again in 1080, and Henry�s forces  took Rome in 1084. Gregory was rescued by Robert Guiscard, but the  devastation of Rome forced the pope to withdraw to Salerno, where he  died.</p><p>Gregory IX orig. Ugo di Segni (b. before 1170�d. Aug. 22, 1241,  Rome) Pope (1227�41) who founded the papal Inquisition. In 1227 he  excommunicated Frederick II when the emperor delayed in keeping his  pledge to lead a Crusade. Gregory ordered an attack on the kingdom of  Sicily in the emperor�s absence, but his forces were defeated. In 1234 he  published the Decretals, a code of canon law that remained fundamental  to Catholicism until World War I. Attacking heresy in southern France  and northern Italy, he strengthened the Inquisition.

Tebaldo Visconti (b. c. 1210, Piacenza, Lombardy  [Italy]�d. Jan. 10, 1276, Arezzo, Tuscany) Pope (1271-76). He kept the  Holy Roman Empire from disintegrating, by securing the election of  Rudolf I as emperor. Rudolf in return promised to lead a new Crusade and  renounced claims in Rome and the papal territories. In 1274 Gregory  issued a new constitution reforming the assembly of cardinals that elects  a new pope. He also initiated a Crusade and worked to unify the Greek  and Roman churches. He was beatified Sept. 12, 1713. His feast days are  January 28 and February 4.</p><p>Gregory XIII orig. Ugo Buoncompagni (b. June 7, 1502, Bolo�  gna, Romagna�d. April 10, 1585, Rome, Papal States) Pope (1572-85)  who promulgated the Gregorian calendar. After teaching at the Univer�  sity of Bologna, he served as a delegate to the Council of Trent, became  a cardinal in 1565, and was elected pope in 1572. A promoter of the  Counter-Reformation, he sought to execute the reform decrees of the coun�  cil. He compiled the Index librorum prohibitorum and founded several col�  leges and seminaries, delegating their direction to the Jesuits. Aided by  an astronomer and a mathematician, he corrected the errors in the Julian  calendar and issued the Gregorian calendar (1582), which was later  adopted worldwide.</p><p>Gregory, Augusta, Lady orig.

With William Butler Yeats, she helped found the  Irish Literary Theatre (1898) and the Abbey Theatre (1904). She wrote  many dialect comedies based on Irish peasant life, including those col�  lected in Seven Short Plays (1909). She also translated plays by Moliere  and others into an Anglo-Irish dialect that she called �Kiltartan� and  translated and arranged Irish sagas into continuous narratives, published  as Cuchulain of Muirthemne (1902) and Gods and Fighting Men (1904).</p><p>Gregory of Nazianzus \,na-ze-'an-z9s. Saint (b. c. 330, Arianzus,  near Nazianzus, in Cappadocia, Asia Minor�d. c. 389, Arianzus; East�  ern feast day January 25 and 30; Western feast day February 2) One of  the Church Fathers of Eastern Orthodoxy. He was ordained a priest in  Nazianzus in 362. He helped his friend Basil the Great combat Arianism.  Though consecrated bishop of Sasima in 372, he did not take possession  of the bishopric, instead retiring to a life of contemplation and study. He  was noted for his defense of the doctrine of the Holy Trinity and of the  Nicene Creed. In 380 he took over the Great Church of Constantinople,  but, after being denied acknowledgment as bishop, he once again retired.</p><p>Gregory of Nyssa \'nis-o. Saint (b. c. 335, Caesarea, Cappadocia,  Asia Minor�d. c. 394; feast day March 9) Eastern Orthodox theologian  and mystic. Initially a teacher of rhetoric, he turned to religion under the  influence of his brother, Basil the Great, and was consecrated bishop of  Nyssa in 372. Deposed by Arian opposition in 376, he was restored to  office in 378 after the death of the Arian emperor Valens. An associate of  Gregory of Nazianzus, he became a leading defender of the doctrine of  the Holy Trinity. His writings include The Great Catechesis, a classic out�  line of Orthodox theology that examines the place of the sacraments in  the church. A Christian Platonist, he shared Origen�s hope for ultimate  universal salvation.</p><p>Gregory of Tours \'tur. Saint orig. Georgius Florentius (b.</p><p>Nov. 30?, 538/539, Clermont, Aquitaine?�d.

Born into an aristocratic family that had  produced several bishops of what is today central France, Gregory suc�  ceeded his cousin as bishop of Tours in 573. He was involved in numer�  ous political events and in open dispute with the king, Chilperic I. His fame  rests on his History of the Franks , a chief source for knowledge of the  6th-century Franco-Roman kingdom. His other writings, including Lives  of the Fathers, on the lives of saints, and seven books of miracles, afford  unique evidence of religious and social life in Merovingian France.</p><p>Gregory the Great See Saint Gregory I</p><p>Grenada Ngrs-'na-doX Island country.

Cur�  rency: East Caribbean dollar. Grenada is  the most southerly of the Lesser Antilles,  lying about 100 mi (160 km) north of Ven�  ezuela; its territory includes the southern</p><p>Grenadines. Volcanic in origin, it is dominated by a thickly forested moun�  tain ridge rising to 2,757 ft (840 m) at Mount St. Catherine. The south�  ern coast is indented with beaches and natural harbours. The tropical  maritime climate supports rich vegetation. Often called the Isle of Spice,  Grenada is known for its nutmeg, cinnamon, and vanilla as well as for  cocoa. It has a developing market economy dependent on agricultural  exports and tourism. The chief of state is the British sovereign, repre�  sented by the governor-general; the head of government is the prime min�  ister. The warlike Carib Indians dominated Grenada when Christopher  Columbus sighted the island in 1498 and named it Concepcion; the Car-  ibs ruled it for the next 150 years. In the early 1670s it became subject to  the French crown and remained so until 1762, when British forces cap�  tured it. In 1833 the island�s black slaves were freed. Grenada was the  headquarters of the government of the British Windward Islands (1885�  1958) and a member of the West Indies Federation (1958-62). It became  a self-governing state in association with Britain in 1967 and gained its  independence in 1974. In 1979 a left-wing government took control in a  bloodless coup. Relations with its U.S.-oriented Latin American neigh�  bours became strained as Grenada leaned toward Cuba and the Soviet  bloc. In order to counter this trend, the U.S. invaded the island in 1983;  democratic self-government was reestablished in 1984. Grenada�s rela�  tions with Cuba, once suspended, were restored in 1997.</p><p>grenade Small explosive, chemical, or gas bomb used at short range.  Invented in the 15th century, it became so important that 17th-century  European armies had specially trained grenade throwers, or grenadiers.  After c. 1750 grenades were largely abandoned because the increasing  range and accuracy of firearms had lessened opportunities for close com�  bat. They returned to widespread use in the 20th century, when their  effectiveness in World War I trench warfare made them a standard part of  the combat infantryman�s equipment, which they have remained. Most  common is the explosive grenade, with a core of TNT or another high  explosive encased in an iron jacket and a fuse that detonates it either on  impact or after a brief (usually four-second) delay. Chemical and gas gre�  nades generally burn rather than explode.</p><p>Grenadines \,gre-n3-'denz\, The Chain of about 600 islands and islets,  southeastern Lesser Antilles, West Indies.

Having joined the Royal National Mission to Deep Sea Fish�  ermen, he initiated missionary service to the fishermen of Labrador and  became absorbed in improving conditions there. He raised funds through  speaking tours and books.

Nov. 13,1770, London, Eng.)  English politician. He entered Parliament in 1741, held a number of min�  isterial appointments, then served as prime minister (1763-65). His policy  of taxing the American colonies, initiated by his Revenue Act of 1764 and  the Stamp Act of 1765, started the train of events leading to the American  Revolution. He was unpopular for the prosecution of John Wilkes for sedi�  tious libel and his clumsy handling of the Regency Act of 1765, alienating  George III and leading to the fall of his ministry. In opposition thereafter,  Grenville helped bring about the passage of the Townshend Acts (1767).</p><p>Gresham's law Observation that �bad money drives out good.� It is  named for Sir Thomas Gresham (1519-1579), financial agent of Queen  Elizabeth I, who was one of the first to elucidate it (he had been preceded  by Copernicus). The meaning expressed is that, if two coins have the same  face value but are made from metals of unequal value, the cheaper will  tend to drive the other out of circulation; the more valuable coin will be  hoarded or used for foreign exchange instead of for domestic transactions.</p><p>Grettis saga Latest of the Icelanders' sagas, written c. 1320. It tells of the  brave and wellborn Grettir, who at 14 kills a man and is outlawed. He  spends his years of exile performing brave deeds. Returning to Iceland, he  saves the people from a ghost that is ravaging the countryside, which in  dying curses him with a growing fear of the dark. Outlawed again, his  increasing fear keeps him from hiding himself, and he is finally over�  whelmed with the aid of witchcraft. The saga�s distinction rests on its  hero�s complex character and its skillful incorporation of folklore motifs.</p><p>Gretzky, Wayne (Douglas) (b. Jan. 26, 1961, Brantford, Ont., Can.)  Canadian ice-hockey player, considered the greatest in the history of the  game. As centre and captain for the Edmonton Oilers (1979-88), he led  his team to four Stanley Cup victories, becoming the first player to aver�  age more than two points a game. He was traded successively to the Los  Angeles Kings (1988), the St. Louis Blues (1996), and the New York  Rangers (1996). When he ended his career in 1999, he held 61 National  Hockey League (NHL) records. He holds the all-time NHL records for  goals (894), assists (1,963), and points (2,857), as well as corresponding  seasonal records (92 goals, 163 assists, 215 points). He is the only player  to have led the league in scoring for seven consecutive years (1980-87)  and the only one named most valuable player for eight consecutive sea�  sons (1979-87).</p><p>Greuze Vgrcez,\ English Vgr3(r)z\, Jean-Baptiste (b.

His first exhibited painting, The Father Reading  the Bible to His Children, won him immediate success at the Salon of 1755.  Throughout the 1760s he won acclaim with such sentimental works as The  Village Betrothal (1761) and Prodigal Son (c. 1765). Hoping to gain admis�  sion to the academy as a history painter, he submitted a large historical  work; when it was rejected, he refused to exhibit anywhere but his own  studio for 30 years. He earned a living with morality pictures and images of  young women in innocent disarray, but in time his popularity waned. The  reaction against his sentimental genre paintings resulted in critical neglect  of his drawings and portraits, which display great technical gifts.</p><p>Grevy \gra-'ve\, (Francois-Paul-) Jules (b.

A law�  yer, he was a leader of the liberal opposition in the legislature, then  became president of the National Assembly (1871-73) and of the Cham�  ber of Deputies (1876). In 1879 he was elected to the presidency and  sought to minimize presidential powers, preferring a strong legislature.  He resisted nationalist demands for revenge against Germany after the  Franco-Prussian War and opposed colonial expansion. He was forced to  resign in 1887 by scandals affecting his son-in-law, though he himself  was not implicated.</p><p>Grew, Nehemiah (baptized Sept. 26, 1641, Mancetter Parish, War�  wickshire, Eng.�d. March 25, 1712, London) British botanist. A physi�  cian and professor, Grew�s training in animal anatomy led to his interest  in that of plants. His writings noted the existence of cells and coined such  terms as radicle (for the embryonic root), plume (for the primary bud of  a plant embryo; now called plumule), and parenchyma (for unspecialized  cells). His Anatomy of Plants (1682) contained the first thorough account  of plant anatomy; its many excellent wood engravings represented the  three-dimensional, microscopic structure of plant tissue. He presented,  among other fundamental discoveries, the suggestion that the stamen  (with its pollen) is the male sex organ and the pistil corresponds to the  female sex organ. With Marcello Malpighi, Grew is considered a founder  of the science of plant anatomy.</p><p>Grey, Charles Grey, 2nd Earl (b. March 13, 1764, Falloden,  Northumberland, Eng.�d. July 17, 1845, Howick, Northumberland) Brit�  ish politician, leader of the Whig Party, and prime minister (1830-34).  Grey entered Parliament in 1786 and soon became prominent among the  aristocratic Whigs, led by Charles James Fox, in opposition to William Pin�s  conservative government. In 1806 Grey became first lord of the Admi�  ralty in Lord Grenville�s government, and, when Fox died the same year.  Grey became foreign secretary and leader of the Foxite Whigs. In 1807  the dismissal of the ministry and the loss of his seat for Northumberland  because of his Catholic sympathies left Grey with a distaste for office.  From 1815 to 1830 he was more patron than leader of the divided Whig  opposition. In 1830 he became prime minister with popular backing for  parliamentary reform. After considerable debate and conflict, he won  adoption of the Reform Bill of 1832.</p><p>Grey, Sir Edward, 3rd Baronet (b. April 25, 1862, London,  Eng.�d.

During the Moroccan cri�  ses (1905, 1911), he supported France against Germany, but with equivo�  cations that caused diplomatic  confusion. After the assassination of  Francis Ferdinand (1914), Grey pro�  posed that Austria-Hungary obtain  satisfaction from Serbia by occupy�  ing Belgrade. When all peace moves  failed, he maneuvered a divided Brit�  ish cabinet into World War I, about  which he commented, �The lamps  are going out all over Europe; we  shall not see them lit again in our  lifetime.� He was responsible for the  secret Treaty of London (1915).</p><p>Grey, Lady Jane (b.

(64-69  cm) high and weighs 60-70 lbs  (27-32 kg). Streamlined and slender,  it can reach a speed of about 45 mph  (72 kph). Greyhounds hunt by sight  and may be used to hunt hares, deer,  foxes, and small game. They are fre�  quently raced for sport.</p><p>Greyhound Lines, Inc. U.S.  corporation that has provided the  major intercity bus transportation in  the U.S. and Canada. It was founded in 1926 as Motor Transit Manage�  ment. Backed by the railroads, the company soon had a network of lines  spreading across the country. It adopted its current name in 1930. By 1933  Greyhound�s routes covered 40,000 mi (65,000 km). In the early 1980s  deregulation of the bus-transit industry led Greyhound to drop many local  bus lines. In 1987 Greyhound Corp. sold its bus operations, and Grey�  hound Lines, Inc., became an independent corporation devoted to inter�  city bus transportation. It was purchased in 1999 by Canada�s Laidlaw  Inc., a waste-management company.</p><p>greylag Most common Eurasian representative ( Anser anser ) of the  so-called gray goose, and ancestor of all Occidental domestic geese.

Sept. 4, 1907, Bergen) Norwegian composer. His parents were  persuaded by violinist Ole Bull to send Grieg to Leipzig for music study,  and he later studied with Niels Gade and others in Copenhagen, where  he became inspired with the ideal of a Norwegian national music. He fre�  quently performed as a pianist and often accompanied his wife in recitals  of his songs. His incidental music to Henrik Ibsen�s play Peer Gynt (1875)  became, with his piano concerto (1868), perhaps his best-known work.  Highly popular in his time, he is still regarded as Norway�s greatest com�  poser. His other works include Symphonic Dances (1897), Lyric Suite  (1904), more than 150 songs, and many works for piano, including 66  Lyric Pieces (1867-1901) and From Holberg�s Time (1884).</p><p>Grien, Hans Baldung See Hans Baldung</p><p>Grierson Vgrir-S3n\, Sir George Abraham (b.

While holding a succession of British government  posts in Bengal (1873-98), Grierson carried out pioneering research on  South Asian, particularly Indo-Aryan, languages. In 1898 he began work  on the 19-volume Linguistic Survey of India and spent the next 30 years  publishing data on hundreds of languages and dialects. His work was of  enormous value; nevertheless, his hypothetical linguistic constructs such  as �Rajasthani,� �Bihari,� and �Lahnda� misled most nonspecialists.</p><p>Griffes Vgrif-3s\, Charles T(omlinson) (b.

He also starred in its screen version (1958)  after making a strong film debut in A Face in the Crowd (1957). He starred  in many television shows, using his native Blue Ridge drawl to portray  homespun characters such as the sheriff in the popular comedy series The  Andy Griffith Show (1960-68). He later starred in the dramatic series  Matlock (1986-91).</p><p>Griffith, Arthur (b. March 31, 1871, Dublin, Ire.�d. Aug. 12, 1922,  Dublin) Irish journalist and nationalist, principal founder of Sinn Fein. As a  young man, he edited political newspapers and urged passive resistance to  British rule. He lost influence with the extreme nationalists when he did not  participate in the Easter Rising (1916) but regained it when the British jailed  him with other Sinn Fein members. In 1918 the Irish members of the House  of Commons declared a republic and chose Eamon de Valera as president  and Griffith as vice president. In 1921 Griffith led the Irish delegation to the  self-government treaty conference and was the first Irish delegate to accept  partition, embodied in the Anglo-Irish Treaty (1921). When the Dail nar�  rowly approved it in 1922, de Valera resigned and Griffith was elected  president. Exhausted from overwork, he died soon after.</p><p>Griffith, D(avid) W(ark) (b.

After acting in tour�  ing stage companies, he sold film scenarios to the Biograph Co., which  hired him as a director (1908-13). In over 400 films for Biograph he  developed filmmaking as an art form with techniques such as the close-  up, the scenic long shot, and crosscutting, and he collaborated with cin�  ematographer Billy Bitzer to create fade-out, fade-in, and soft-focus shots.  He nurtured the careers of future stars such as Mary Pickford, Lillian Gish,  Mack Sennett, and Lionel Barrymore. His epic dramas The Birth of a  Nation (1915) and Intolerance (1916) greatly influenced later filmmak�  ers. After cofounding United Artists Corp. in 1919, he directed Broken  Blossoms (1919), Way Down East (1920), and Orphans of the Storm  (1921). His last films were Abraham Lincoln (1930) and The Struggle  (1931). He is regarded as one of the seminal figures in the history of  motion pictures.</p><p>Griffith, Emile (Alphonse) (b.

His early tragedies include The Ancestress (1817), Sap�  pho (1818), and the pessimistic The Golden Fleece (1821). The Waves of  Sea and Love (1831) is often considered his greatest tragedy; another  masterpiece is A Dream Is Life (1834), an Austrian Faust. Three other  tragedies were found among his papers after his death.

From 1835 they wrote letters and pamphlets urg�  ing Southern women to use moral force against slavery, and they freed  the slaves they had persuaded their mother to apportion to them as their  inheritance. They lectured on antislavery throughout New England as the  first female agents of the American Anti-Slavery Society, enlisting women  in the abolitionist cause and becoming pioneers in the women�s rights  movement.

They spent most of their  lives in literary research as librarians  and professors at the Universities of  Gottingen and Berlin. They are most  famous for Kinder- und Haus-  marchen (1812-15), known in  English as Grimm�s Fairy Tales, a  collection of 200 tales taken mostly  from oral sources, which helped  establish the science of folklore.</p><p>Together and separately, they also  produced many other scholarly stud�  ies and editions. Wilhelm�s chief  solo work was The German Heroic  Tale (1829); Jacob�s German  Mythology (1835) was a highly  influential study of pre-Christian  German faith and superstition. Jacob�s extensive Deutsche Grammatik  (1819-37), on the grammars of all Germanic languages, elaborates the  important linguistic principle now known as Grimm�s law. In the 1840s  the brothers began work on the Deutsches Worterbuch, a vast historical  dictionary of the German language that required several generations to  complete and remains the standard work of its kind.</p><p>Jacob (right) and Wilhelm Grimm, oil  portrait by Elisabeth Jerichau-  Baumann, 1855; in the National-  Galerie, Berlin</p><p>COURTESY OF THE STAATUCHE MUSEEN ZU BERLIN</p><p>grinding machine Machine tool that uses a rotating abrasive grind�  ing wheel to change the shape or dimensions of a hard, usually metallic,  workpiece.

Other Griqua living around  Kimberley met no serious challenge to their land rights until diamonds  were discovered there. With the aid of the British, this group resisted  absorption into the Orange Free State.

He studied engineering at the Madrid  School of Arts and Manufactures (1902-04). In 1906 he moved to Paris  and began producing drawings in the Art Nouveau style for newspapers.  He became involved with the Cubist artists, notably Pablo Picasso, and  soon developed his own version of Synthetic Cubism, a style more severe  and calculated than that of other Cubists. His works, typically still lifes,  are characterized by rigorously geometric compositions. His technique  included the use of paper collage. He also produced sculpture, book illus�  trations, and sets and costumes for Sergey Diaghilev�s Ballets Russes.</p><p>grisaille \gre-'zl, gro-'zalX Painting technique by which an image is  executed entirely in shades of gray  and usually modeled to produce the  illusion of sculpture or relief. It was  used especially by 15th-century  Flemish painters (e.g., Jan van Eyck�s  Ghent Altarpiece, 1432) and in the  late 18th century to imitate Classical  sculpture in wall and ceiling decora�  tion. It is sometimes used to produce  monotone underpainting for translu�  cent oil colours.

The son of an architect, he studied in Munich and Berlin and in  1907 joined the office of Peter Behrens. In 1919 he became director of the  Staatliches Bauhaus Weimar. He designed a new school building and  housing for the Bauhaus when it moved to Dessau (1925); with its dynamic  International Style composition, asymmetrical plan, smooth white walls  set with horizontal windows, and flat roof, the building became a monu�  ment of the Modernist movement. In 1934 Gropius fled Germany for  Britain, and in 1937 he arrived in the U.S, taking a position at Harvard  University. At the Bauhaus and as chair (1938-52) of Harvard�s archi�  tecture department, he established a new prototype of design education,  which ended the 200-year supremacy of the French Ecole des Beaux-Arts.  Among his most important ideas was his belief that all design�whether  of a chair, a building, or a city�should be approached in essentially the  same way: through a systematic study of the particular needs and prob�  lems involved, taking into account modem construction materials and  techniques without reference to previous forms or styles.</p><p>Gros Vgro\, Antoine-Jean (b.

In the 1790s he  accompanied Napoleon on his campaigns as his official battle painter. The  dramatic power of such paintings as Napoleon Visiting the Pesthouse at  Jaffa (1804) influenced Theodore Gericault and Eugene Delacroix. When  David went into exile after Napoleon�s defeat, Gros took over his studio  and tried to work in the Neoclassical style. His best works after 1815 were  portraits.

After studying art in Dresden and Berlin, he  began selling caricatures to magazines. During World War I he served in  the German army; discharged as unfit in 1917, he moved into a garret  studio in Berlin, and by the end of the war he had developed a graphic  style that combined a highly expressive use of line with ferocious social  satire. His depictions of war and depravity provided some of the most  vitriolic social criticism of his time. From 1918 to 1920 he was a promi�  nent member of the Dada group in Berlin. His Face of the Ruling Class  (1921) and Ecce Homo (1922), collections of drawings featuring greedy  capitalists, war profiteering, and social decadence, earned him an inter�  national reputation.

Jan. 14, 1999, Pontedera, Italy) Polish-born U.S. stage director. He joined  the Polish Laboratory Theatre of Wroclaw in 1959 and founded a perma�  nent company in 1965. The Laboratory Theatre made its U.S. debut with  Akropolis (1969); it was followed by Undertaking Mountain (1977) and  Undertaking Earth (1977-78), by which time Grotowski was living  mostly in the U.S. Known as an avant-garde theorist, he sought to create  dramatic tension by setting up emotional confrontations between audience  and actors. His book Towards a Poor Theater (1968) emphasized the cen�  trality of the actor and advocated minimal stage sets. He influenced U.S.  experimental theatre movements, notably the Living Theatre.</p><p>ground squirrel Any of numerous relatively short-legged, terrestrial  rodents of the squirrel family (Sciu-  ridae), found in North America,</p><p>Mexico, Africa, Europe, and Asia.</p><p>The name is often applied to chip�  munks. Ground squirrels belong to the  genera Ammospermophilus, Xerus,</p><p>Atlantoxerus , and Spermophilus.</p><p>They live in burrows, sometimes in  colonies. Though primarily herbi�  vores, some feed on insects and other  small animals and on carrion. Many  species collect food, carrying it in  their cheek pouches, and store it in  their burrows. Those in cold areas may hibernate in winter; those in dry  areas may become dormant in summer. Species range from about 7 to 20 in.  (17-52 cm) in length, including the tail.</p><p>groundhog See woodchuck</p><p>Groundhog Day (February 2) In the U.S., the day that the ground�  hog predicts whether spring will be coming soon. If, on emerging from  his hole, he sees his shadow, there will be six more weeks of winter; if  not, spring is imminent. The tradition stems from English beliefs about  seeing shadows on Candlemas (also February 2).</p><p>groundnut Any of several plants that bear edible fruit or other nutlike  parts. Three are legumes: Arachis hypogaea, the peanut, the fruit of which  is a legume or pod rather than a true nut; Apois americana, also called  wild bean and potato bean, the tubers of which are edible; and Lathyrus  tuberosa, also called earth-nut pea. Cyperus esculentus, nut sedge or yel�  low nut grass, is a papyrus relative (sedge family) that also bears edible  tubers, especially in the variety called chufa or earth almond.</p><p>groundwater or subsurface water Water that occurs below the  surface of the Earth, where it occupies spaces in soils or geologic strata.  Most groundwater comes from precipitation, which gradually percolates  into the Earth. Typically, 10-20% of precipitation eventually enters aqui�</p><p>fers. Most groundwater is free of pathogenic organisms, and purification  for domestic or industrial use is not necessary. Furthermore, groundwa�  ter supplies are not seriously affected by short droughts and are available  in many areas that do not have dependable surface water supplies.</p><p>groundwater table See water table  Group of Seven See Group of Seven</p><p>Group Theatre New York theatre company (1931�41) founded by  Harold Clurman, Cheryl Crawford, and Lee Strasberg to present U.S. plays  of social significance.

Cobb, and Stella Adler�staged John Howard Lawson�s  Success Story (1932), Sidney Kingsley�s Men in White (1933), Clifford  Odets�s Waiting for Lefty (1935) and Golden Boy (1937), Irwin Shaw�s  Bury the Dead (1936), and William Saroyan�s My Heart�s in the High�  lands (1939), among many other plays.</p><p>group theory In modern algebra, a system consisting of a set of ele�  ments and an operation for combining the elements, which together sat�  isfy certain axioms. These require that the group be closed under the  operation (the combination of any two elements produces another element  of the group), that it obey the associative law, that it contain an identity  element (which, combined with any other element, leaves the latter  unchanged), and that each element have an inverse (which combines with  an element to produce the identity element). If the group also satisfies the  commutative law, it is called a commutative, or abelian, group. The set of  integers under addition, where the identity element is 0 and the inverse  is the negative of a positive number or vice versa, is an abelian group.  See also field theory.</p><p>group therapy Form of psychotherapy in which several patients or cli�  ents discuss their personal problems, usually in the presence of a therapist  or counselor. In one approach to group therapy, the chief aim is to raise  members� awareness and morale and combat feelings of isolation by cul�  tivating a sense of belonging to the group; a notable example is Alcoholics  Anonymous. The other principal approach strives to foster free discussion  and uninhibited self-revelation; members are helped to self-understanding  and more successful behaviour through mutual examination of their reac�  tions to people in their lives, including one another.</p><p>Groupe Islamique Armee (GIA) See Armed Islamic Group</p><p>grouper Any of numerous species of fishes (family Serranidae) widely  distributed in warm seas, especially members of the genera Epinephelus  and Mycteroperca. Groupers are characteristically large-mouthed, heavy�  bodied fishes. Some species grow larger than 6 ft (about 2 m) long and  heavier than 500 lb (225 kg). Groupers are usually dull green or brown;  some species can change their colour pattern, and deepwater individuals  may be much redder than nearshore ones. They are prime food fishes,  though a few species carry a toxic substance in their flesh and can cause  poisoning when consumed, and they provide sport for anglers and  spearfishermen. See also jewfish; sea bass.</p><p>grouse Any of various game birds in the family Tetraonidae (order Gal-  liformes), including the prairie chicken  and ptarmigan, or the sandgrouse  (order Columbiformes). The best-  known Old World species is the  black grouse ( Lyrurus tetrix ) of  Wales, Scotland, Scandinavia, and  northern central Europe. The male,  iridescent blue-black with white  wing bars, may be 22 in. (55 cm)  long and weigh about 4 lbs (almost  2 kg); the smaller female is mottled  brown and barred with black. Grouse  are noted for the male�s communal courtship dances. The best-known  North American species is the ruffed grouse.</p><p>Grove, Andrew S. (b. Sept. 2, 1936, Budapest, Hung.)

He became secre�  tary of the Crystal Palace in 1852, and he would write program notes for  its concerts for 40 years. His extensive contributions to William Smith�s  Dictionary of the Bible led to his establishing the Palestine Exploration  Fund in 1865. He served as editor of Macmillan�s Magazine (1868-83).  In 1873 he began work on his four-volume Dictionary of Music and  Musicians ; expanded to 20 volumes in subsequent editions, it is today the  world�s foremost music encyclopedia. He served as first director of the  Royal College of Music (1883�92), an institution he was largely respon�  sible for placing on a firm professional and physical foundation.</p><p>growing season Period of the year, also called frost-free season, dur�  ing which growing conditions for native vegetation and cultivated crops  are the most favourable. It usually becomes shorter as distance from the  equator increases. In equatorial and tropical regions the growing season  ordinarily lasts all year; at higher latitudes (e.g., the tundra), it may last  as little as two months or less. It also varies according to elevation above  sea level: higher elevations tend to have shorter growing seasons.</p><p>growth hormone (GH) or somatotropin Xso-.ma-to-'tro-ponV Pep�  tide hormone secreted by the anterior lobe of the pituitary gland. It pro�  motes growth of bone and other body tissues by stimulating protein  synthesis and fat breakdown (for energy). Excessive production causes  gigantism, acromegaly, or other malformations; deficient production results  in dwarfism, dramatically relieved if GH is given before puberty. Genetic  engineering techniques now permit large-scale production of adequate  amounts of GH for that purpose.</p><p>growth ring In a cross section of the stem of a woody plant, the amount  of wood added during a single growth period. In temperate regions this  period is usually one year, in which case the growth ring may be called  an annual ring. In tropical regions growth rings may not be discernible  or are not annual. Even in temperate regions growth rings are occasion�  ally missing; and sometimes a second, or �false,� ring may be deposited  during a single year (e.g., following defoliation by insects). Nevertheless,  annual rings have been used in dating ancient wooden structures, espe�  cially those of American Indians in the dry U.S. Southwest. Changes in  ring width are a source of information about ancient climates.</p><p>Gruen, David See David Ben-Gurion</p><p>Grunewald YgriE-na-.valtA English Vgrti-no-.woldV, Matthias orig.  Mathis Gothardt Neithardt or Mathis Gothart Nithart (b. c.</p><p>1480, Wurzburg, bishopric of Wurzburg�d. August 1528, Halle, arch�  bishopric of Magdeburg) German painter. Details of his early life are  vague. By c. 1509 he was court painter to the archbishop of Mainz and  had established a successful career, concentrating on religious themes.  Around 1511 he was commissioned to add two wings to the Assumption  of the Virgin altarpiece recently completed by Albrecht Durer. In 1515 he  completed his most important commission, the wings of the Isenheim  Altarpiece in the Antonite monastery in southern Alsace (now in the  museum in Colmar, Fr.). Considered his masterpiece, it features distorted  figures, extreme emotional intensity, brooding colour, and draperies that  expand and contract in accordion pleats, a hallmark of his style. About  10 paintings and 35 drawings survive. He had no known pupils and, unlike  his contemporaries, did not produce woodcuts or engravings, but his  painterly achievement remains one of the most striking in the history of  northern European art.</p><p>grunion Vgron-yonN Edible Pacific fish (Leuresthes tenuis ) found along  the western coast of the U.S. In the warm months, it lays its eggs in beach  sand during a full or new moon when the tide cycle is at its peak.

Mexico�s second largest city, it lies near the Rio Grande de Santiago at  an elevation of about 5,100 ft (1,550 m). Founded by the Spanish in 1531,  it was relocated several times under pressure from Indians. In 1810 it was  occupied briefly by the independence leader Miguel Hidalgo. Since 1940  it has become a major industrial producer while retaining a rich agricul�  tural trade. The governor�s palace, begun in 1743, is a noted example of  Spanish Mexican architecture. Guadalajara is the site of two universities.</p><p>Guadalcanal \ l gwa-d s l-k3- , nal\ Island (pop., 1999: 109,382), Solomon  Islands, west-central South Pacific Ocean. The largest of the Solomon  Islands, Guadalcanal has an area of 2,069 sq mi (5,358 sq km); the  national capital, Honiara, lies on the northern coast. The economy is based  mainly on fishing and agriculture, with some gold mining. The island was  visited by the Spanish in the 16th century and by the British in the late  18th century; it was annexed in 1893 as part of the British Solomon  Islands Protectorate. During World War II it was the scene of prolonged  fighting between U.S. and Japanese forces (1942^-3), which resulted in  the Allied capture of a Japanese air base there. Several naval battles were  also fought in the region. Ethnic tensions between Guadalcanal islanders  and migrants from the nearby island of Malaita worsened after World War  II. After the islands achieved independence from Great Britain in 1978,  ethnically based disputes simmered on the island, sparking violence and  rioting in the late 20th and early 21st centuries.</p><p>Guadalquivir \,gwa-d 3 l-ki-'vir\ River Arabic Wadi al-Kabir</p><p>Vwa-de-.al-ko-'bhA ancient Baetis River, southern Spain.

It drew  the U.S.-Mexico boundary at the Rio Grande and the Gila River. For $15  million the U.S. received more than 525,000 sq mi (1.36 million sq km)  of land and agreed to settle the more than $3 million in claims made by  U.S. citizens against Mexico. By leaving Mexicans unsure of their coun�  try�s future and reopening the question of the expansion of slavery in the  vast territory ceded to the U.S., the treaty was a factor in the civil wars  that followed in both countries.</p><p>Guadalupe V.gwa-do-'lii-paV Mountains National Park National  park, western Texas, U.S. Established in 1972, it occupies an area of  86,416 acres (34,998 hectares) east of El Paso.

Saint-Barthelemy and the northern two-  thirds of Saint-Martin are dependencies, lying 150 mi (240 km) northwest.  Forests and tree crops such as coffee abound on the mountains of Basse-  Terre, while sugarcane is cultivated on the generally low-lying Grande-  Terre. The Carib Indians held off the Spanish and French for a number of  years before the islands became part of France in 1674. The British occu�  pied Guadeloupe for short periods in the 18th�19th century; the islands  became officially French in 1816. In 1946 they were made a department of  France. Tourism has benefited the economy in recent decades.</p><p>Guadiana \,gwa-de-'a-n3\ River River, Spain and Portugal.

Its headwaters rise in the mountains  of Spain�s Cuenca province; west of Daimiel they form marshy lakes,  known as Ojos del Guadiana (�Eyes of the Guadiana�), a noted wildfowl  sanctuary. As the river continues west, it cuts a series of gorges through  the Toledo Mountains, now the site of several dams that provide hydro�  electric power.</p><p>Guainia, Rio See Rio Negro</p><p>Guam \'gwam\ Island (pop., 2005 est.: 170,000), largest and southern�  most of the Mariana Islands, Micronesia, western Pacific Ocean. Guam is  an unincorporated U.S. territory; its capital is Agana. With an area of 217  sq mi (561 sq km), it is divided into a northern plateau and a southern  chain of volcanic hills. The indigenous population is Chamorro, Malayo-  Indonesian with a considerable admixture of Spanish, Filipino, and Mexi�  can ancestry. They speak Chamorro in addition to English, both official  languages. Possibly visited by Ferdinand Magellan in 1521, Guam was  formally claimed by Spain in 1565 and remained Spanish until it was  ceded to the U.S. in 1898 after the Spanish-American War. During World  War II the Japanese occupied the island (1941-44). It subsequently  became a major U.S. air and naval base. In 1950 it was made a U.S. ter�  ritory and placed under the Department of the Interior. The military bases  and tourism are the island�s economic mainstays.</p><p>Guan Hanqing Vgwan-'han-'chiqV or Kuan Han-ch'ing (b. 1241?,  Dadu, China�d. 1320?, China) Chinese dramatist. He belonged to a writ�  ers� guild that provided plays for performing groups. His plays often dealt  with everyday events and sympathetically portrayed women of low social  standing. He wrote over 60 plays, 14 of which survive, including Injus�  tice to Dou E, Butterfly Dream, and Saving a Prostitute. Guan is often  considered the greatest playwright of the Chinese classical theatre.</p><p>Guan Yu Vgwan-'yu\ or Kuan Yu or Guan Di (d. 219) Military hero  of the Three Kingdoms era (3rd century ad) who started his career as the  bodyguard of Liu Bei, the founder of one of the three kingdoms. He was  captured and executed but his fame and popularity continued to grow.  China�s rulers conferred ever greater titles on him until in 1594 he was  canonized as Guan Di, god of war and protector of China. Thousands of  temples were constructed in his honor. His cult spread to Korea in the  17th century, where it was believed that he saved the country from Japa�  nese invasion.</p><p>guanaco \gwo-'na-ko\ Slender-bodied South American lamoid ( Lama  guanacoe; see alpaca).

The adult stands 43 in. (110 cm) tall at the shoulder and  is pale brown above and white below, with a grayish head. The downy  fibre covering the young is valued for textiles, and guanaco pelts are used  by the fur industry.</p><p>Guanajuato \,gwa-na-'hwa-to\ State (pop., 2000: 4,663,032), central  Mexico. It covers 11,773 sq mi (30,491 sq km), and its capital is Gua�  najuato city. It lies on the interior plateau. The north is mountainous, while  the south, consisting of fertile plains, is largely devoted to agriculture.  The state is drained by several rivers, including the Lerma. The first  Spanish settlement was at San Miguel de Allende (1542). During colo�  nial times it was an important silver-mining area. The region became a  state in 1824. Mining (silver, gold, tin, lead, and opals) remains the prin�  cipal economic activity.</p><p>Guanajuato City (pop., 2000: 74,874), capital of Guanajuato state,  Mexico. It lies about 6,700 ft (2,000 m) above sea level. Founded in 1554,  it is an outstanding example of a Spanish colonial city. One of the great�  est silver-mining centres of the 16th century, the city�s wealth was mani�  fest in its richly endowed churches, several of which date to the 17th  century. In 1810 it was the first major city to fall to the independence  leader Miguel Hidalgo. It later declined until increased tourist trade and  federal support of mining and agriculture in the 1930s brought recovery.  It is the site of the University of Guanajuato (1945).</p><p>Guandi See Guan Yu</p><p>Guangdong \'gwaq-'duq\ or Kuang-tung conventional Kwang-  tung Southernmost mainland province (pop., 2000 est.: 86,420,000),  China. It is bounded by the South China Sea to the south, and along its  coast are Hong Kong and Macao; also bordering it are Fujian, Jiangxi, and  Hunan provinces and Guangxi autonomous region. It has an area of 76,100  sq mi (197,100 sq km). The capital is Guangzhou (Canton). It was first  incorporated into the Chinese empire in 222 bc. Overseas trade through  Guangzhou swelled the population of the province in the 16th-17th cen�  turies. It was the site of illicit opium importation by the British, which  led to the First Opium War in 1841. Kowloon was ceded to Britain in 1860  and Macao to Portugal in 1887; both were restored to China in the late  1990s. Guangdong was a base for the Nationalists under Sun Yat-sen from  1912. Japanese forces occupied the province in 1938�45. Its centuries of  foreign contact have given it a degree of self-sufficiency that sets it apart  from the rest of China; more recently it has developed several special  economic zones.</p><p>Guangwudi \ , gwaq- , wu- , de\ or Kuang-wu ti orig.

Lying on the Gulf of  Tonkin, it is bordered by Vietnam and by Guangdong, Hunan, Guizhou,  and Yunnan provinces. It has an area of 85,100 sq mi (220,400 sq km)  and is largely hilly, with river valleys where rice is grown. Its capital is  Nanning. Its recorded history dates from 45 bc, and it was given its present  name during the Yuan dynasty in ad 1279. With Guangdong, it became  the base of the Nationalists under Sun Yat-sen in the early 20th century.  Local leaders later formed the Guangxi Clique in opposition to Chiang  Kai-shek, who crushed their revolt in 1929. Guangxi was declared a prov�  ince of the People�s Republic of China in 1949, and in 1958 it became  an autonomous region. Noted for its agricultural production, it is also an  important source for forest products.</p><p>Guangzhou Vgwaq-'joX or Kuang-chou conventional Canton City  (pop., 2003 est.: 4,653,131), capital of Guangdong province, China.  Located on the Zhu (Pearl) River about 80 mi (130 km) from the sea, it  is southern China�s chief port. Incorporated in the Chinese empire in the  3rd century bc, it later became an important city under the Ming dynasty.  The first Chinese seaport opened to foreigners, it was regularly visited by  Arab and Hindu traders and, in the 16th century, by the Portuguese. The  English arrived in the late 17th century, followed by the French and Dutch.  Guangzhou�s resistance to the English opium trade led to war (1839-42),  and it was occupied by the British and French in 1856-61. In the late 19th  century it was the seat of revolutionary political ideas promoted by the  Nationalist Party. It was bombed and then occupied by the Japanese in  1938-45. Its industrial growth subsequently expanded, and, with China�s  renewed ties to the West, it was designated as one of several economic  investment areas for foreigners in 1984. One of China�s largest cities, its  expanding economy added to the region�s growth.</p><p>guanine \'gwa-,nen\ Organic compound of the purine family, often  called a base, consisting of two rings, each containing both nitrogen and  carbon atoms, and an amino group.

Lying in the mountains 21 mi  (34 km) north of strategic Guantanamo Bay, it was founded in 1819.  French refugees from Haiti aided in colonizing the area, and many cul�  tural characteristics, including the architecture, show their influence. Cat�  alans were also among the early settlers. It is the centre of an agricultural  region producing sugarcane and coffee.</p><p>Guantanamo Bay Inlet of the Caribbean Sea, southeastern Cuba. It  is one of the largest bays in the world: its harbour is about 6 mi (9 km)  wide and 12 mi (19 km) long. Its strategic importance was recognized  during the Spanish-American War, when U.S. marines landed there in  1898. A U.S. naval base, established in 1903, remained there even after  hostilities erupted between the two countries in 1959; the base served as  an internment facility for suspected Islamic militants beginning in 2002.</p><p>Guanyin See Avalokitesvara</p><p>Guapore \,gwa-p6-'ra\ River or Itenez \e-'ta-nes\ River, west-central  South America.

It is navigable  along its entire 1,087-mi (1,749-km) course. In contrast with the brown,  silt-laden Mamore, the Guapore has unusually clear water; for several  miles below their juncture, the two colours remain distinct.</p><p>Guarani \,gwar-3-'ne\ South American Indian group that has tradition�  ally inhabited eastern Paraguay and adjacent areas of Brazil and Argen�  tina. Aboriginal Guarani were formerly warlike and took captives to be  sacrificed (and allegedly eaten). Their shifting cultivation required them  to move their settlements every few years. The descendants of Guarani  women and Spanish ranchers are modem Paraguay�s rural population.  Only a few scattered communities of true Guarani remain, but Paraguay  still claims a strong Guarani heritage, and most of the million peasants  living along the Paraguay River near Asuncion speak a version of the  aboriginal Guarani language.</p><p>Guardi \'gwar-de\, Francesco (b. 1712, Venice�d. 1793, Venice)  Italian landscape painter. He and his  two brothers collaborated in a flour�  ishing studio-workshop in Venice;  their sister was married to Giovanni  Battista Tiepolo. By the 1750s  Francesco was producing vedute  (view paintings) of Venice. His many  romantic impressions of the city  never achieved the popularity of  Canaletto�s near-photographic  records of its architecture, and his  work came to be appreciated only  after the rise of Impressionism.</p><p>guardian In law, one who has, or  is legally appointed to, the care and  management of another, usually a  minor.

In 1971 he earned critical acclaim for his farci�  cal play The House of Blue Leaves. Two Gentlemen of Verona (1972, with  Mel Shapiro), a rock-musical version of William Shakespeare�s comedy,  won him Tony and New York Drama Critics Circle awards. His later  works include Six Degrees of Separation (1990; film, 1993) and Four  Baboons Adoring the Sun (1992).</p><p>Guarini \gwa-'re-ne\, (Giovanni) Battista (b. Dec. 10, 1538,  Ferrara�d.

With Tasso, he is cred�  ited with developing the genre of pastoral drama. Guarini retired in 1582  and wrote his best-known work, The Faithful Shepherd (1590), a pasto�  ral tragicomedy that became one of the most famous and widely trans�  lated works of the age.</p><p>Guarneri \gwar-'ner-e\, Andrea Italian musical-instrument maker.  He apprenticed with Nicolo Amati from 1641 to 1654 (see Amati family).  Setting up his own shop in Cremona, he made violas and cellos as well  as violins. His sons Pietro (1655-1720) and Giuseppe (1666-1740?)  worked with their father; by 1683 Pietro had moved to Mantua and set  up his own business, though he made few instruments. Giuseppe inher�  ited the Cremona business from his father in 1698. During his lifetime,  Andrea Guarneri�s name was obscured by Antonio Stradivari�s, but his  violins and cellos are today highly prized. His sons Pietro (1695-1762)  and Bartolomeo (1698-1744) were also instrument makers; Bartolomeo,  called Guarneri del Gesu, was one of the finest in history; his violins show  the influence of both his father and Stradivari and are known for their full  sound.</p><p>Guatemala \ l gwa-t3-'ma-b\ officially Republic of Guatemala</p><p>Country, Central America.

Guatemala has a devel�  oping market economy based largely on agriculture; coffee is its leading  export, along with sugar and bananas. It is a republic with one legislative  body; its head of state and government is the president. From simple  farming villages dating to 2500 bc, the Maya of Guatemala and the  Yucatan developed a sophisticated civilization. Its heart was the northern  Peten, where the oldest Mayan stelae and the ceremonial centre of Tikal  are found. Mayan civilization declined after ad 900, and the Spanish  began subjugating the descendants of the Maya in 1523. Independence  from Spain was declared by the Central American colonies in Guatemala  City in 1821, and Guatemala was incorporated into the Mexican Empire  until its collapse in 1823. In 1839 Guatemala became independent under  the first of a series of dictators who held power almost continuously for  the next century. In 1945 a liberal-democratic coalition came to power  and instituted sweeping reforms. Attempts to expropriate land belonging  to U.S. business interests (see United Fruit Co.) prompted the U.S. gov�  ernment in 1954 to sponsor an invasion by exiled Guatemalans. In the  following years Guatemala�s social revolution came to an end, and most  of the reforms were reversed. Chronic political instability and violence  henceforth marked Guatemalan politics; most of some 200,000 deaths that  resulted from subsequent political violence were blamed on government  forces. Thousands more died in 1976 when a powerful earthquake dev�  astated the country. In 1991 Guatemala abandoned its long-standing  claims of sovereignty over Belize, and the two countries established dip�  lomatic relations. It continued to experience violence as guerrillas sought  to seize power. A peace treaty was signed in 1996, but labour discontent,  widespread crime and poverty, and violations of human rights continued  into the 21st century.</p><p>Guatemala City City (pop., 1994: city, 823,301; 1999 est.: metro area,  3,119,000), capital of Guatemala. The largest city in Central America, it  lies in the central highlands at an elevation of about 4,900 ft (1,490 m).  Founded in 1776, it replaced earthquake-damaged Antigua Guatemala as  the capital of the captaincy general of Guatemala. After independence  from Spain, it served as capital of the province of Central America under  the Mexican Empire of Agustin de Iturbide and later of the Republic of  Guatemala. It is the country�s political, social, cultural, and economic  centre and the site of San Carlos University of Guatemala (1676); its  museums include the National Archaeological Museum, which houses a  collection of rare Mayan artifacts. The modern city was largely rebuilt  after a series of earthquakes in 1917-18; it was severely damaged again  in 1976.</p><p>Guatimozin See Cuauhtemoc</p><p>guava Any of many trees and shrubs of the genus Psidium (myrtle fam�  ily), native to the New World tropics.

It is situated  on the Guayas River 45 mi (72 km) from the Pacific Ocean. Founded by  the Spanish in 1537, it was frequently attacked by buccaneers. In 1822 it  was the scene of a historic conference between revolutionary leaders  Simon Bolivar and Jose de San Martin, after which Bolivar emerged as sole  leader of the South American liberation movement. As the focus of Ecua�  dor�s international trade and domestic commerce, it has become a major  Pacific port. It is the site of three universities.</p><p>Guayas Vgwl-as\ River River, western Ecuador. Its two principal tribu�  taries, the Daule and Babahoyo rivers, rise on the western slopes of the  Andes Mountains and unite just above the city of Guayaquil. Below the  city it flows through a low-lying delta and enters the Gulf of Guayaquil.  Its length to the end of the longest tributary is about 200 mi (320 km).

As a member of the Duma, he attempted to  enact more reforms but became increasingly critical of the government  for its disdain for the constitution and for the influence of Grigory Ras�  putin. When the Russian Revolution of 1917 broke out, he was sent to  receive Nicholas�s abdication, and later he served briefly as minister of  war and the navy. After the Bolsheviks seized power in October, he emi�  grated to Paris.</p><p>Gudbrands Valley Norwegian Gudbrandsdalen</p><p>Vgud-.brans-.da-lonV Valley, south-central Norway.

The terms Guelph  (see Welf dynasty) and Ghibelline (from Waiblingen, the castle of the  Welfs� Hohenstaufen opponents) first acquired significance in Italy dur�  ing the reign of the Hohenstaufen emperor Frederick I Barbarossa, who tried  to assert imperial authority over northern Italy and was opposed by Pope  Alexander III. The split between the Guelphs, who sided with the papacy,  and the Ghibellines, who were sympathetic to the Holy Roman emperors,  contributed to chronic strife in the cities of northern Italy in the 13th�14th  century, reflected in Dante�s Divine Comedy.</p><p>Guercino \gwar-'che-no\, II (Italian: "The Squinter") orig.

Strongly influenced by the  Bolognese school, he was called to Rome in 1621 by the Bolognese pope  Gregory XV and, among other commissions, decorated the Villa Ludovisi;  the ceiling fresco Aurora is painted to appear as if there were no ceiling,  so that Aurora�s chariot is seen to float directly over the building. He  returned to his native town of Cento in 1623. In 1642, upon the death of  Guido Reni, he moved to Bologna and was its leading painter until his  death. One of the outstanding draftsmen of his age, he had a profound  impact on the development of 17th-century Baroque decoration.</p><p>Guernsey Vgom-zeX Second largest of the Channel Islands.

The  name derived from a French physician and member of the National</p><p>Assembly, Joseph-Ignace Guillotin (1738-1814), who was instrumental  in passing a law requiring all sentences of death to be carried out �by  means of a machine,� so that execution by decapitation would no longer  be confined to nobles and executions would be as painless as possible.  The last execution by guillotine in France took place in 1977.</p><p>Guin, Ursula Le See Ursula Le Guin</p><p>Guinea \'gi-ne\ officially Republic of Guinea formerly French  Guinea Country, western Africa. Area: 94,926 sq mi (245,857 sq km).  Population (2005 est.): 9,402,000. Capital: Conakry. The Fulani people are</p><p>in the majority, followed by the Malinke, the  Susu, and many other groups. Language:  French (official). Religions: Islam; also  Christianity. Currency: Guinean franc.</p><p>Facing the Atlantic Ocean to the west,  Guinea has four geographic regions. Lower Guinea comprises the coast  and coastal plain, which are interspersed with lagoons and mangrove  swamps. To the east the Fouta Djallon highlands rise sharply from the  coastal plain to elevations above 3,000 ft (900 m); western Africa�s three  major rivers�the Niger, Senegal, and Gambia �originate there. Upper  Guinea comprises the Niger Plains. The Forest Region, an isolated high�  land in the southeast, rises to 5,748 ft (1,752 m) at Mount Nimba, the coun�  try�s highest peak. Most of the country has a humid tropical climate, and  there are extensive tracts of tropical rainforest. Export crops include rice,  bananas, and coffee. Guinea is a major world producer of bauxite. Its devel�  oping mixed economy is based on agriculture, mining, and trade. Guinea is  a multiparty republic with one legislative house; the head of state and gov�  ernment is the president, assisted by the prime minister. In successive  migrations c. ad 900, the Susu swept down from the desert and pushed the  original inhabitants, the Baga, to the Atlantic coast. Small kingdoms of the  Susu rose in importance in the 13th century and later extended their rule to  the coast. In the mid-15th century the Portuguese visited the coast and  developed a slave trade. In the 16th century the Fulani established domi�  nation over the Fouta Djallon region; they ruled into the 19th century. In the  early 19th century the French arrived and in 1849 proclaimed the coastal  region a French protectorate. In 1895 French Guinea became part of the  federation of French West Africa. In 1946 it was made an overseas territory  of France, and in 1958 it achieved independence. Following a military coup  in 1984, Guinea began implementing Westernized government systems. A  new constitution was adopted in 1991, and the first multiparty elections  were held in 1993. During the 1990s Guinea accommodated several hun�  dred thousand war refugees from neighbouring Liberia and Sierra Leone,  and conflicts between these countries and Guinea have continued to flare  up over the refugee population.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Guinea &#x25BA; Guise I 815</p><p>Guinea, Gulf of Great inlet of the Atlantic Ocean on the western Afri�  can coast.

Languages: Portuguese (official), Balante,  Fula, Malinke, Mandyako. Religions: traditional beliefs, Islam, Christian�  ity. Currency: CFA franc. Most of the country consists of low, marshy  terrain and flat plateau. The climate is generally hot and tropical. Much  of the wildlife is aquatic; crocodiles, snakes, and birds such as pelicans  and flamingos abound. Guinea-Bissau has a developing, primarily agri�  cultural economy; cashews and peanuts are the main cash crops. It is a  multiparty republic with one legislative house; its head of state and gov�  ernment is the president assisted by the prime minister. More than 1,000  years ago the coast of Guinea-Bissau was occupied by agriculturists using  iron implements. They grew irrigated and dry rice and were also the major  suppliers of marine salt to the western Sudan. At about the same time, the  area came under the influence of the Mali empire and became a tributary  kingdom known as Gabu. After 1546 Gabu was virtually autonomous;  vestiges of it lasted until 1867. The earliest overseas contacts came in the  15th century with the Portuguese, who imported slaves from the Guinea  area to the offshore Cape Verde Islands. Portuguese control of Guinea-  Bissau was marginal despite their claims to sovereignty there. The end of  the slave trade forced the Portuguese inland in search of new profits. Their  subjugation of the interior was slow and sometimes violent; it was not  effectively achieved until 1915, though sporadic resistance continued until  1936. Guerrilla warfare in the 1960s led to the country�s independence  in 1974, but political turmoil continued, and the government was over�  thrown by a military coup in 1980. A new constitution was adopted in  1984, and the first multiparty elections were held in 1994. A destructive  civil war in 1998 was followed by a military coup in 1999, but the coup  was followed by elections.</p><p>guinea fowl Any of a family (Numididae) of African birds, sometimes  placed in the family Phasianidae. One species ( Numida meleagris) is  widely domesticated for its flesh and, because it gabbles loudly at the least</p><p>alarm, as a �watchdog� on farms.</p><p>Wild forms of this species are known  as helmet guinea fowl because of  their large bony crest. Many varieties  are widespread in the savannas and  scrublands of Africa, and the guinea  fowl has been introduced into the  West Indies and elsewhere. About 20  in. (50 cm) long, in its typical form it  has a bare face, brown eyes, red and  blue wattles at the bill, white-spotted  black plumage, and a hunched pos�  ture. It lives in flocks and feeds on  seed tubers and some insects.</p><p>guinea pig Domesticated species  (Cavia porcellus ) of South American  cavy (family Caviidae). It resembles  most other cavies in being stout,  short-legged, and about 10 in. (25  cm) long. It has small ears, no exter�  nal tail, and a coat that is black, tan,  cream-coloured, brown, white, or a combination of these colours. Hair  length and texture vary among varieties. It feeds largely on grass and other  green plants. Domesticated in pre-Incan times, it was introduced into  Europe in the early 16th century. It is a popular pet and a valuable research  animal.</p><p>guinea worm or medina worm or dragon worm Nematode  (Dracunculus medinensis) that is a common parasite of humans and other  mammals in tropical Asia and Africa and has been introduced into the  West Indies and tropical South America. The female grows to 20-48 in.  (50-120 cm) long; the male, which dies upon mating, is only about 0.5-  1.1 in. (12-29 mm) long. Both sexes live in the connective tissue of the  host animal. Humans become infected when they drink water containing  tiny crustaceans (e.g., copepods) that have eaten guinea-worm larvae. The  disease the guinea worm carries, called dracunculiasis, can be extremely  debilitating and painful.</p><p>Guinevere See Arthurian legend</p><p>Guinness Vgi-nos\ (de Cuffe), Sir Alec (b.

He fought in Francis I�s army and was badly wounded at the siege of Bou�  logne (1545), earning him the nickname �the Scarred.� He led French  armies in other victories against the English and the Spanish. On the  accession of Francis II (1559), Guise became grand master of the royal  household. The Bourbons launched a conspiracy to overthrow the Guises,  who learned of the plot and ruthlessly suppressed it (1560). When Cathe�  rine de Medicis became regent (1560), she supported the Bourbons (who</p><p>Vulturine guinea fowl [Acryllium vul-  turinum)</p><p>S.C.

When Catherine de Medi-  cis turned to the Guises in 1572 for help in removing the Huguenot Gas-  pard II de Coligny, Henri, who blamed Coligny for the murder of his father,  the 2nd duke de Guise, helped plan the Massacre of Saint Bartholomew's  Day. Fearing Guise�s growing popularity, Henry III made peace with the  Huguenots in 1576, and Guise angrily countered by forming the Holy  League. After Guise�s victory in the War of the Three Henrys (1588), Henry  was forced to surrender to the Holy League�s demands, and Guise was  appointed lieutenant general of France. Soon afterward the king�s body�  guard stabbed Guise to death; the next day his brother, Louis II (1555�  88), Cardinal de Guise, was also murdered.</p><p>Guise, Henri II de Lorraine, 5th duke de (b.

After being sentenced to death for his part in a conspiracy against Car�  dinal de Richelieu (1641), he fled to Brussels and commanded the Austrian  troops against France. He unsuccessfully led the Neapolitans in their war  against Spain (1647, 1654), then spent the rest of his life at the French  court, trying unsuccessfully to revive the power of the Guise dynasty.</p><p>Guise Vgez\, house of Noble French Roman Catholic family that  played a major role in French politics during the Reformation. Claude de  Lorraine (1496-1550) was created the 1st duke de Guise in 1527 for his  service to Francis I in the defense of France. Claude�s sons Francois, 2nd  duke de Guise, and Charles, cardinal de Lorraine (1524-1574), gained  great power during the reign of Francis II. Supported by Spain and the  papacy, their persecution of the Huguenots led to the unsuccessful  Amboise Conspiracy (1560), an attempted assassination of the leaders of  the Guise party and transfer of power to the house of Bourbon. The Guise-  led massacre of a Huguenot congregation at Vassy precipitated the Wars  of Religion, in which Henri I, 3rd duke de Guise, was a prominent leader.  Charles de Lorraine, 4th duke de Guise (1571-1640), lived through the  rapid decline of the family�s power. Henri II, 5th duke de Guise, tried  unsuccessfully to revive the family�s power; the direct line expired with  the death of his grand-nephew in 1675.</p><p>guitar Plucked stringed instrument.

By 1800 it was being strung with</p><p>strings</p><p>� MERRIAM-WEBSTER INC.</p><p>six single strings; 19th-century innovations gave it its modern form. Mod�  ern classical guitar technique owes much to Francisco Tarrega (1852�  1909), and Andres Segovia gave the instrument prominence in the concert  hall. However, it has always been primarily an amateur�s instrument, and  it remains an important folk instrument in many countries. The 12-string  guitar is strung in six double courses. The Hawaiian, or steel, guitar is  held horizontally and the strings are stopped by the pressure of a metal  bar, producing a sweet glissando tone. The electric guitar represented a  major development. Electric pickups were attached to the acoustic guitar  in the 1920s. In the 1940s Les Paul invented the solid-body guitar; lack�  ing a soundbox, it transmits only the string vibrations. With its long-  sustained notes, affinity for strong amplification, and capacity for</p><p>producing wailing melodic lines as well as harshly percussive rhythms,  it soon became the principal instrument of Western popular music.</p><p>Guitry \ge-*tre\, Sacha (b.

The term is often limited today to the so-called big guns, can�  non larger than a howitzer or mortar. It may also be used to refer to mili�  tary small arms such as the rifle, machine gun, and pistol, as well as to  nonmilitary firearms such as the shotgun. Though the Chinese used gun�  powder in warfare from the 9th century, guns were not developed until  the Europeans acquired gunpowder in the 13th century. The earliest guns  (c. 1327) resembled old-fashioned soda bottles; they apparently were fired  by applying a red-hot wire to a touchhole drilled through the top. Sepa�  rating the barrel and the powder chamber resulted in breechloaders, which  continued to be used in naval swivel guns and fortress wallpieces well  into the 17th century. Small arms, as distinguished from hand cannon, did  not exist until the development of the matchlock in the 15th century.

In the final  stage the soul achieves the release known as moksha. See also Eightfold  Path, nirvana.</p><p>gunite See shotcrete</p><p>Gunn, Thomfson William) (b. Aug. 29, 1929, Gravesend, Kent,  Eng.�d. April 25, 2004, San Francisco, Calif., U.S.) British-U.S. poet.  Educated at Cambridge and Stanford universities, he lived in San Fran�  cisco from the 1950s and taught for many years at the University of Cali�  fornia, Berkeley. His early verse appeared in Fighting Terms (1954) and  The Sense of Movement (1957); in the late 1950s his poems became more  experimental. My Sad Captains (1961), Moly (1971), Jack Straw�s Castle  (1976), and The Passages of Joy (1982) discuss his homosexuality; The  Man with Night Sweats (1992) has AIDS as a subject. Other collections  include Collected Poems (1993) and Boss Cupid (2000).</p><p>gunpowder Any of several mixtures used as propelling charges in  guns and as blasting agents in mining. The first such explosive was black  powder, a mixture of saltpeter (potassium nitrate), sulfur, and charcoal. It  originated in the 9th century in China and made its way west in the 13th  century. The recipe was refined and finally fixed in the 14th century; black  powder is still widely used for ignition charges, primers, fuses, blank  charges in military ammunition, and fireworks. In 1838 it was discovered  that cotton could be made explosive by dipping it in concentrated nitric  acid, and the form of nitrocellulose known as guncotton came into use as  an ingredient of gunpowder in the 1860s. In the 1880s Paul Vieille (1854-  1934) used nitrocellulose to create the first smokeless gunpowder; mod�  ern gunpowder consists of either nitrocellulose alone or a combination of  nitrocellulose and nitroglycerin.</p><p>Gunpowder Plot (1605) Conspiracy by English Roman Catholic zeal�  ots to blow up Parliament and kill James I. Angered by James�s refusal to  grant more religious toleration to Catholics, a group of conspirators led  by Robert Catesby (1573-1605) recruited Guy Fawkes to their plot. One  member warned his brother-in-law Lord Monteagle not to attend Parlia�  ment on the appointed day (November 5, 1605), and Monteagle alerted  the government. Fawkes was arrested in a rented cellar under the palace  at Westminster, where he had concealed 20 barrels of gunpowder. Under  torture, he revealed the names of the conspirators, and they were all either  killed while resisting arrest or executed in 1606. The plot bitterly inten�  sified Protestant suspicions of Catholics.</p><p>Gunther, John (b. Aug. 30, 1901, Chicago, Ill., U.S.�d. May 29,  1970, New York, N.Y.) U.S. journalist and author.

Nov. 1892, Shawan, Luoshan county, Sichuan prov�  ince, China�d. June 12, 1978, Beijing) Chinese scholar and writer. In his  youth he abandoned medical studies to devote himself to foreign litera�  ture, producing a popular translation of Johann Wolfgang von Goethe�s  Sorrows of Young Werther (1922). He wrote prolifically in every genre,  including poetry, fiction, plays, nine autobiographical volumes, transla�  tions of Western works, and historical and philosophical treatises, includ�  ing a monumental study of ancient inscriptions. Initially a liberal  democrat, he became a Marxist in the 1920s, and his work was banned  by the Guomindang. Following the 1949 revolution, he was named to the  highest official literary positions and later to the presidency of the Chi�  nese Academy of Sciences.</p><p>Guo Xiang \'gw6-'shyaq\ or Kuo Hsiang (d. 312, China) Chinese  Neo-Daoist philosopher. He was a high government official who adapted  and completed another philosopher�s unfinished commentary on the writ�  ings of Zhuangzi. Interpreting dao (�the way�) as nothingness, he argued  that it cannot produce being and cannot be a first cause. He concluded  that there is no agent of causality in the universe; all things spontaneously  produce themselves, and everything has its own nature. Happiness comes  from following that distinctive nature, and dissatisfaction and regret come  from failing to follow it. He also interpreted Daoist �nonaction� to mean  spontaneous action rather than sitting still, a deviation from original Dao-  ism that agreed with Zhuangzi�s thought.</p><p>Guomindang Vgwo-'min-'daqV See Nationalist Party</p><p>guppy Colourful, freshwater, live-bearing topminnows ( Lebistes retic-  ulatus and Poecilia reticulata; see  killifish) popular as pets in home  aquariums.

The Gupta era was once  regarded as India�s Classical period, but new archaeological evidence has  given the Mauryan empire that designation. Nevertheless, the Gupta period  is noted for the flourishing of Sanskrit literature (see Kalidasa), its sophis�  ticated metal coins, its advanced mathematics (which made use of deci�  mal notation and the numeral zero and at that time was more advanced  than anywhere else), and its astronomical advances.</p><p>Gur \'gur\ languages formerly Voltaic \val-'ta-ik\ languages  Branch of the huge Niger-Congo language family.

He apparently traveled in the Middle East, Africa, and Central Asia  as a young man. He taught in Moscow and St. Petersburg, and in 1919  he founded the Institute for the Harmonious Development of Man at Tif-  lis (now Tbilisi), Georgia. In 1922 he reestablished the institute at Fon�  tainebleau, France, gathering a group of followers who lived communally,  engaging in philosophical dialogue, ritual exercises, and dance. His basic  assertion was that ordinary living was akin to sleep and that through spiri�  tual discipline it was possible to achieve heightened levels of vitality and  awareness. The Fontainebleau centre closed in 1933, but Gurdjieff con�  tinued to teach in Paris until his death.</p><p>gurdwara \gur-'dwa-ra\ Sikh place of worship. Each gurdwara houses  a copy of the Adi Granth and serves as a meeting place for worship,  including recitation, singing, and explication of scripture.

Pilgrimages are  often made to the gurdwaras associated with the Sikh Gurus' lives, nota�  bly the Golden Temple.</p><p>Gurjara-Pratihara Vgur-'ja-ro-pro-te-'ha-roV dynasty Either of two  dynasties of Hindu India. The Pratiharas were the most important dynasty  of 9th-century northern India. The line of Haricandra ruled in Mandor,  Marwar (present-day Jodhpur, Rajasthan state), in the 6th-9th centuries,  generally with feudatory status. The line of Nagabhata ruled first at Ujjain  and later at Kannauj in the 8th�11th centuries. This line is generally con�  sidered the more important one; at its peak of prosperity and power (c.  836-910), it rivaled the Gupta dynasty in the extent of its territory. The  last important Pratihara king was driven from Kannauj by MahmOd of  Ghazna (1018). Other Gurjara lines existed, but they did not take the sur�  name Pratihara.</p><p>guru In Hinduism, a personal spiritual teacher. In ancient India, knowl�  edge of the Vedas was transmitted through oral teaching from guru to  pupil. The rise of the bhakti movement further increased the importance  of gurus, who were often looked on as living embodiments of spiritual  truth and were identified with the deity. They prescribed spiritual disci�  plines to their devotees, who followed their dictates in a tradition of will�  ing service and obedience. Men or women may be gurus, though generally  only men have established lineages. See also Guru.</p><p>Guru Title of the first 10 leaders of Sikhism. The first was Nanak, who  before his death (1539) began the tradition that allowed the Guru to name  his successor. He was followed by Angad (1539-1552), Amar Das, Ram-  das (1574-1581), Arjan, Hargobind, Hari Rai, Hari Krishen (1661-1664),  Tegh Bahadur (1664-1675), and Gobind Singh. In time the Guru became  as much a military as a spiritual leader. Gobind Singh discontinued the  office in 1708 and vested its authority in the Sikh sacred scripture, the Adi  Granth.

Gustafson attended the University of Oxford; he settled  in New York after World War II but later returned to Canada. His work  shows a development from traditional form and manner to an elliptical  style reflecting the influence of Anglo-Saxon verse and the metrical  experiments of Gerard Manley Hopkins. His later works, usually consid�  ered his better writings, include Rivers Among Rocks (1960), Conflicts of  Spring (1981), and Shadows in the Grass (1991). He also published col�  lections of short stories.</p><p>Gustav I Vasa orig. Gustav Eriksson Vasa (b. May 12,</p><p>1496?�d. Sept. 29, 1560, Stockholm, Swed.) King of Sweden (1523-60)  and founder of the Vasa dynasty. The son of a Swedish senator, Gustav  joined the rebellion against Christian II of Denmark, who controlled most  of Sweden. He became leader of the rebels (1520) and secured crucial aid  from the rich free city of Liibeck. This aid enabled Gustav to establish  Sweden�s independence, and in 1523 he was elected king. Gustav  imposed heavy taxes to pay his debts to Liibeck and to strengthen royal</p><p>authority and lands. He hoped to seize the Roman Catholic church�s  wealth, and he pushed Sweden toward becoming a Protestant (Lutheran)  country. An autocratic ruler, he built a strong monarchy and an efficient  administration.</p><p>Gustav II Adolf Latin Gustavus Adolphus (b. Dec. 9, 1594,  Stockholm, Swed.�d. Nov. 6, 1632, Liitzen, Saxony) King of Sweden  (1611-32) who made Sweden a major European power. The son of Charles  IX, Gustav inherited his father�s dynastic quarrels with Sigismund III Vasa  and until 1629 faced a legitimist invasion from Poland. He ended the war  with Denmark in 1613, but Sweden was forced to pay a crushing war  indemnity. He ended the war with Russia (1617) and annexed Ingria and  Kexholm. Internal tensions were largely resolved by his trusted chancel�  lor, Axel Gustafsson Oxenstierna. Gustav�s sweeping domestic reforms  included establishing an efficient central administration and improving  education. Resuming the war with Sigismund in 1621, Gustav obtained  much of Polish Livonia (Latvia and Estonia). He saw his Polish cam�  paigns as part of the struggle of Protestantism against the Counter-  Reformation. He entered the Thirty Years' War in 1630 as a defensive  maneuver, to secure the Swedish state and church from danger. An out�  standing military tactician, he led an army of unusual quality, and his  position was strengthened by alliances with France, Brandenburg, and  Saxony. Success in the Battle of Breitenfeld let him sweep through cen�  tral Germany and claim large territorial cessions, particularly Pomerania  (1631). At Liitzen in 1632, the Swedes defeated Albrecht W.E. von Wal�  lenstein�s army, but Gustav was killed in battle.</p><p>Gustav III (b. Jan. 24, 1746, Stockholm, Swed.�d. March 29, 1792,  Stockholm) King of Sweden (1771-92). The son of King Adolf Freder�  ick (1710-71), he succeeded to a weakened Swedish throne. Unable to  mediate between the contending factions of the Riksdag (legislature), in  1772 he established a new constitution that increased the crown�s power.  He introduced numerous enlightened reforms, which antagonized the  nobility. He waged an unpopular war on Russia (1788-90), and when a  group of Swedish officers mutinied, he again augmented royal authority  in a new constitution (1789). Gustav planned to form a league of Euro�  pean monarchs to oppose the French Revolution, but the Swedish nobil�  ity remained opposed to him and had him assassinated. Gustav was a  patron of the arts and a playwright, and his reign was known as the Swed�  ish enlightenment.</p><p>Gustav IV Adolf (b. Nov. 1, 1778, Stockholm, Swed.�d. Feb. 7, 1837,  Sankt Gallen, Switz.) King of Sweden (1800-09). Son of the assassinated  Gustav III, he came to the throne in 1792 under the regency of his uncle  Charles, duke of Sodermanland (later Charles XIII). In 1805 Gustav  brought Sweden into the European coalition against Napoleon. When  Russia joined with France in 1807, Gustav remained in the field, though  he knew it would mean a Russian attack on Finland. Denmark-Norway  also declared war on Sweden, causing the loss of additional territory. In  1809 Gustav was overthrown in a coup, and his heirs were declared ineli�  gible to succeed him. He and his family left Sweden for exile, settling in  Switzerland.</p><p>Gustav V orig. Oscar Gustaf Adolf (b. June 16, 1858, Stockholm,  Swed.�d. Oct. 29, 1950, Stockholm) King of Sweden (1907-50). The  son of Oscar II (1829-1907), he entered the army and traveled widely  before succeeding his father in 1907. In a period of expanding democracy  within his country, Gustav proved a capable constitutional monarch.  Though he favoured the Allies in World Wars I and II, he was a firm pro�  ponent of Swedish neutrality.</p><p>Gut of Canso See Strait of Canso</p><p>Gutenberg VgU-Un-.borgV Johannes (Gensfleisch zur Laden  zum) (b. c. 1395, Mainz�-d. probably Feb. 3, 1468, Mainz) German  inventor of a method of printing from movable type. Born to a patrician  family in Mainz, he apparently worked at such crafts as goldsmithing and  gem cutting in Mainz and Strasbourg and was experimenting with print�  ing by 1438. He obtained backing in 1450 from the financier Johann Fust  (c.. 1400-66); Fust�s impatience and other factors led to Gutenberg�s loss  of his establishment to Fust in 1455. Gutenberg�s masterpiece, and the  first book ever printed from movable type, is the �Forty-Two-Line� Bible,  completed no later than 1455. A magnificent Psalter was published in  1457, after the loss of his press. The only other works still attributed to  him are minor. His invention�s unique elements included a mold, with  which type could be cast precisely and in large quantities; a type-metal  alloy; a new press, derived from those used in winemaking, papermak-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>820 I Guthrie &#x25BA; Guzman</p><p>ing, and bookbinding; and an oil-based printing ink. None of these fea�  tures existed in Chinese or Korean printing, in the existing European  technique of stamping letters on various surfaces, or in woodblock print�  ing. Gutenberg�s invention, seminal to the course of Western civilization,  remained the source of the basic elements of typesetting for 500 years.</p><p>Guthrie, Sir (William) Tyrone (b.

After his first London production in 1931,  he became director of the Shakespeare Repertory Company (1933-34,  1936�45), which performed at the Old Vic and Sadler�s Wells theatres.  His original approach to Shakespearean drama greatly influenced the  20th-century revival of interest in traditional theatre. He also directed  operas such as Peter Grimes (1946) and Carmen (1949) and his own play,  Top of the Ladder (1950). He helped found and direct the Stratford Fes�  tival in Canada (1953-57), influencing the development of Canadian the�  atre. He also founded and directed (1963-66) the Tyrone Guthrie Theater  in Minneapolis.</p><p>Guthrie, Woody orig. Woodrow Wilson Guthrie (b. July 14,  1912, Okemah, Okla., U.S.�d.

With his guitar  and harmonica he sang in the hobo and migrant camps of the Great  Depression, later becoming a musical spokesman for labour and populist  sentiment. He wrote more than a thousand songs, including �So Long (It�s  Been Good to Know Yuh),� �Hard Traveling,� and �Union Maid.� In New  York City he joined Pete Seeger and others in the Almanac Singers; after  serving in World War II, he continued to perform with them for farmer  and worker groups. �This Land Is Your Land� was his most famous song,  and it became an unofficial national anthem. His autobiography, Bound  for Glory (1943), was filmed in 1976.

The first woman director,  she is also generally acknowledged to be the first director to film a nar�  rative story. She directed her first film, The Cabbage Fairy , in 1896 to  demonstrate the entertainment possibilities of the motion-picture camera  manufactured by her employer, Leon Gaumont. She became the Gaumont  film company�s head of production, directing nearly all early Gaumont  films. About 1901 Guy began to work on longer, more elaborate projects,  notably Esmeralda (1905), based on Victor Hugo�s The Hunchback of  Notre Dame, and The Life of Christ (1906). From 1906 to 1907 she  directed about 100 films, using experimental sound technology. She mar�  ried cameraman Herbert Blache in 1907 and followed him to the U.S.,  where in 1910 she founded the successful Solax Company. As president  of Solax she directed about 45 films and supervised nearly 300 other pro�  ductions.

Area: 83,044 sq mi (215,083 sq km). Population (2005 est.):  751,000. Capital: Georgetown. About half the people are of South Asian  descent; most of the rest are of African ancestry. Language: English (offi�  cial). Religions: Christianity (Protestant, Roman Catholic), Hinduism,  Islam. Currency: Guyana dollar. Guyana has a narrow Atlantic coastal  plain that extends up to 10 mi (16 km) inland and includes reclaimed land  protected by seawalls and canals. Inland, a high rainforest covers three-  fourths of the country. The Pakaraima Mountains in the west provide  headwaters for the Essequibo River. Guyana has a developing market  economy with both public and private ownership. Major exports include  sugar, rice, and bauxite. It is a multiparty republic with one legislative  house; its head of state and government is the president. American Indi�  ans inhabited Guyana prior to European settlement, but little is known of</p><p>the territory during the Napoleonic Wars</p><p>and afterward purchased the colonies of Demerara, Berbice, and Esse�  quibo, which were united in 1831 as British Guiana. The slave trade was  abolished in 1807, but emancipation of the 100,000 slaves in the colonies  was not complete until 1838. From the 1840s, South Asian and Chinese  indentured servants were brought to work the plantations; by 1917 almost  240,000 South Asians had migrated to British Guiana. It was made a  crown colony in 1928 and granted home rule in 1953. Political parties  began to emerge, developing along ethnic lines as the People�s Progres�  sive Party (largely South Asian) and the People�s National Congress  (PNC; largely black). The PNC formed a coalition government and led  the country into independence as Guyana in 1966. In 1970 Guyana  became a republic within the Commonwealth; in 1980 it adopted a new  constitution. In the last decades of the 20th century, Guyana moved away  from the socialist approach first taken following independence. At the  beginning of the 21st century, it was still struggling to achieve economic  and political stability.</p><p>Guyenne \ge-'en\ or Guienne ancient Aquitania Historic region,  southwestern France. The Guyenne region corresponds to the modern  departement of Gironde and to most of the departements of Lot-et-  Garonne, Dordogne, Lot, and Aveyron. An old duchy whose capital was  at Bordeaux, it was near the Garonne and Dordogne rivers. From Roman  times until the Middle Ages it was part of the region of Aquitaine. Under  English control during much of the later Middle Ages, Guyenne was  retaken by the French at the beginning of the Hundred Years' War, but in  1360 it was restored, with Aquitaine, to the English. France later recon�  quered the area, and from the 17th century until 1789 Guyenne was part  of the French gouvernement of Guienne and Gascony.</p><p>Guzman \gus-'man\ (Fernandez), (Silvestre) Antonio (b.

The Romans built a military headquarters and major fortress in Gwent,  and the Normans erected castles. Formerly a Welsh county (1974-96), it  has since been divided into several unitary authorities. The economy of  the region relies on both agriculture and industry.</p><p>Gwyn, Nell orig. Eleanor Gwyn (b. Feb. 2,1650, London, Eng.�d.  Nov. 14, 1687, London) British actress. She was selling oranges at the  Drury Lane Theatre when she became the mistress of its leading actor,  Charles Hart, who trained her for the stage. She became the leading come�  dienne of the King�s Company (1666-69) and as �pretty, witty Nell� was  in demand as a speaker of impudent prologues and epilogues. She became  the mistress of Charles II (1669-85) and was popular with the public, who  found her high spirits and frank recklessness welcome antidotes to Puri�  tanism.</p><p>Gwynedd or Gwyneth \'gwi-,neth\ County (pop., 2001: 116,838),  northwestern Wales. It encompasses most of the historic counties of Caer�  narfonshire and Merioneth. Its administrative centre is Caernarfon. The  ancient region of Gwynedd comprised most of northern Wales. The Nor�  mans built castles at Caernarfon and Conwy but did not penetrate inland.  It thus remained a stronghold of Welsh culture, with a high proportion of  Welsh-speaking people. The landscape is mostly mountains of old hard  rock cut by Ice Age glaciers. It includes Snowdonia National Park (1951),  which covers about half its total area. Tourism is economically important.</p><p>gymnasium In Germany, a state-maintained secondary school that pre�  pares pupils for higher academic education. This type of nine-year school  originated in Strasbourg in 1537. Though the usual graduation age is 19  or 20, pupils may terminate their studies at age 16 and enter a vocational  school. Secondary or postprimary education is also provided by middle  schools ( Mittelschulen ), teachers� colleges, and commercial schools.</p><p>gymnastics Competitive sport in which individuals perform optional  and prescribed acrobatic exercises, mostly on special apparatus, in order to  demonstrate strength, balance, and body control. Part of the ancient Olym�  pic Games, gymnastics was virtually reinvented in the modern era by the  German Friedrich Jahn (1778-1852). The sport became part of the revived  Olympics in 1896; women�s gymnastics was instituted in 1936. Men�s  events include the horizontal bar, parallel bars, pommel horse, vaulting, rings,  and floor exercises. Women�s events include the balance beam, uneven par�  allel bars, vaulting, floor exercises, and rhythmic sportive gymnastics.</p><p>gymnosperm Vjim-no-.spornA Any woody plant that reproduces by  means of a seed (or ovule) in direct contact with the environment, as  opposed to an angiosperm, or flowering plant, whose seeds are enclosed by  mature ovaries, or fruits. The four surviving gymnosperm divisions are  Coniferophyta (conifers, the most widespread), Cycadophyta (cycads),  Ginkgophyta (ginkgos), and Gnetophyta. More than half are trees; most of  the rest are shrubs. Gymnosperms occur on all continents except Antarc�</p><p>tica, and especially in the temperate latitudes. Those widely found in the  Northern Hemisphere are junipers, firs, larches, spruces, and pines; in the  Southern Hemisphere, podocarps ( Podocarpus ). The wood of gymno�  sperms is often called softwood to differentiate it from the hardwood of  angiosperms. Many timber and pulp trees are also planted as ornamentals.  Gymnosperms also are a minor source of food; of essential oils used in  soaps, air fresheners, disinfectants, pharmaceuticals, cosmetics, and per�  fumes; of tannin, used for curing leather; and of turpentines. Gymnosperms  were a major component in the vegetation that was compressed over mil�  lions of years into coal. Most are evergreen. They produce male and female  reproductive cells in separate male and female strobili (see cone).</p><p>gynecology See obstetrics and gynecology</p><p>gynecomastia V.gl-no-ko-'mas-te-oV Breast enlargement in a male. It  usually involves only the nipple and nearby tissue of one breast. More  rarely, the whole breast grows to a size normal in a female. True gyneco�  mastia is related to an increase in estrogens. Testicular or pituitary-gland  tumours commonly cause gynecomastia. Similar conditions (pseudogy�  necomastia) are caused by excessive body fat, inflammatory disorders,  granular lesions, or growth of tumours. Treatment involves hormone  therapy, correction of the estrogen disorder, or tumour removal.</p><p>gypsum Vjip-S9m\ Common sulfate mineral, hydrated calcium sulfate  (CaS0 4 -2H 2 0), of great commercial importance. Deposits occur in many  countries, but the U.S., Canada, France, Italy, and Britain are among the  leading producers. Crude gypsum is used as a fluxing agent, soil condi�  tioner, filler in paper and textiles, and retarder in portland cement. About  three-fourths of the total production is calcined for use as plaster of paris  and as building materials in plaster, board products, and tiles and blocks.</p><p>Gypsy see Rom</p><p>gypsy moth Species (. Lymantria dispar) of tussock moth, a serious pest  of trees. The European strain was introduced into eastern North America  c. 1869. The heavy-bodied, weak-flying female is white with black zig�  zag markings and a wingspan of 1.5-2 in. (38-50 mm). The smaller,  darker male is a stronger flier. The voracious larvae can completely defo�  liate deciduous trees within weeks. The larger Asian gypsy moth (wing�  span of about 3.5 in., or 90 mm) is even more threatening because the  female is a stronger flier, enabling it to spread quickly, and the larvae eat  the leaves of both conifers and deciduous trees. It was introduced into  northwestern North America in 1991. Sprayed insecticides remain the  most effective means of control.</p><p>Gypsy Rose Lee See Gypsy Rose Lee</p><p>gyrfalcon Vjsr-.fal-konV Arctic bird of prey ( Falco rusticolus), the larg�  est falcon. It may reach 2 ft (60 cm)  in length. It breeds only in the North  Pole region (and in some Central  Asian highlands) but is sometimes  seen at lower latitudes when food is  scarce. It varies from pure white with  black speckling to dark gray with  barring. Its legs are fully feathered.</p><p>It hunts near the ground for hares,  rodents, and birds of the tundra and  seacoast. In traditional falconry, the  gyrfalcon was the bird of kings.</p><p>gyroscope Vjl-re- I skop\ A  mechanical or optical device used to  maintain orientation during motion.</p><p>A mechanical gyroscope consists of a rapidly spinning wheel set in a  framework that permits it to tilt freely in any direction or to rotate about any  axis. The momentum of such a wheel causes it to retain its attitude when the  framework is tilted. An optical gyroscope, laser or fibre, measures the inter�  ference pattern generated by two light beams, traveling in opposite direc�  tions within a mirrored ring or fibre loop, in order to detect very small  changes in motion. Gyroscopes are used in compasses, in automatic pilots  on ships and aircraft, in the steering mechanisms of torpedoes, in antiroll  equipment on large ships, and in inertial guidance systems.</p><p>Gyrfalcon (Falco rusticolus ) with prey.</p><p>SHELLY GROSSMAN/WOODFIN CAMP &amp; ASSOCIATES</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>822 I H-R diagram &#x25BA; habituation</p><p>H-R diagram See Hertzsprung-Russell diagram</p><p>Ha-erh-pin See Harbin</p><p>Ha Jin (b.

(His prophecy is part of a larger book, The Twelve,  in the Jewish canon.) He was perhaps a Temple musician as well as a  prophet. He denounced the sins of Judah, identifying their enemies the  Chaldeans (Babylonians) as an instrument of God�s punishment, but also  predicted the final triumph of righteousness.</p><p>habeas corpus Vha-be-os-'kor-posV Latin "you should have the  body" In common law, any of several writs issued to bring a party before  a court. The most important such writ ( habeas corpus ad subjiciendum )  is used to correct violations of personal liberty by directing judicial  inquiry into the legality of a detention. Common grounds for relief include  a conviction based on illegally obtained evidence, a denial of effective  assistance of counsel, or a conviction by a jury that was improperly  selected or impaneled. The writ may be used in civil matters to challenge  a person�s custody of a child or the institutionalization of a person  declared incompetent.</p><p>Haber Vha-borX, Fritz (b. Dec. 9, 1868, Breslau, Silesia, Prussia�d.  Jan. 29, 1934, Basel, Switz.) German physical chemist. After early  research in electrochemistry and thermodynamics, he developed, with his  brother-in-law Carl Bosch (1874-1940), the Haber-Bosch process for mak�</p><p>ing ammonia. Intensely patriotic, he directed Germany�s World War I  chemical-warfare efforts, under which poison gas was introduced. His  versatility and his wide-ranging and important work brought him fame  and honour, and he was awarded a 1918 Nobel Prize. In 1933 the Nazi  Party�s anti-Semitic policies led him to resign as head (since 1911) of the  Kaiser-Wilhelm Institute.</p><p>Haber-Bosch Vha-bor-'boshN process or Haber ammonia pro�  cess or synthetic ammonia process First economically feasible  method of directly synthesizing ammonia from hydrogen gas and atmo�  spheric nitrogen. It was developed c. 1909 by Fritz Haber and Carl Bosch  (1874-1940), prompted by rapidly increasing demand for nitrogen fertil�  izer. It was the first industrial process to use high  pressure (200-400 atmospheres) for a chemical  reaction. A catalyst (usually iron) lets it take  place at a moderate temperature (750-1,200 �F [400-  650 �C]), and immediate removal of ammonia as it is  formed favours formation of more of it. Still the cheap�  est means of industrial nitrogen fixation, it is a basic  process of the chemical industry.</p><p>Habermas Vha-bor-.masV Jurgen (b. June 18,  1929) German philosopher associated with the Frank�  furt school. He received his Ph.D. at the University of  Bonn in 1954. He taught primarily at the Johann Wolf�  gang Goethe University in Frankfurt, Ger.; he also  directed the Max Planck Institute in Starnberg (1971�  80). In his Theory of Communicative Action (1985,  1987), he attempts to develop an account of truth  that does not imply that truth is �absolute� or  transcendent�i.e., valid for all people and all  societies at all times. His �discourse� theory of  truth is based on the observation that communication, unlike other forms  of human action, is oriented toward �consent� rather than �success,� in  that it aims to achieve mutual understanding rather to change or master  some aspect of the world. The process of constructing such an under�  standing, however, requires that each individual assume that the utterances  of the other are for the most part �true,� and that the other can provide  reasons to support the truth of his utterances should he be called upon to  do so. The notion of truth is thus not a metaphysical fiction but a regu�  lative ideal that makes communication possible.</p><p>Habima Vho-'be-moV or Habimah Hebrew "Stage" Hebrew theatre  company. Organized in Poland in 1912, it was reestablished in 1917 in  Moscow, where it was encouraged by Konstantin Stanislavsky. Habima�s  production of The Dybbuk (1922) established it as a company of high  artistic merit, and it became affiliated with the Moscow Art Theatre. After  producing The Golem (1925), the group toured Europe and the U.S. In  1931 most of the group moved to Tel Aviv, where they presented Yiddish  and biblical dramas and a repertory of Israeli, classical, and contempo�  rary foreign plays. In 1958 it became the National Theatre of Israel.</p><p>habit In psychology, any regularly repeated behaviour that requires little  or no thought and is learned rather than innate. Some habits (e.g., tying  a shoelace) may conserve higher mental processes for more demanding  tasks, but others promote behavioral inflexibility or are unhealthy. Five  methods are commonly used to break unwanted habits: replacing the old  response with a new one, repeating the behaviour until it becomes  unpleasant, separating the individual from the stimulus that prompts the  response, habituation, and punishment.</p><p>habitat Place where an organism or a community of organisms lives,  including all living and nonliving factors or conditions of the surround�  ing environment. A host organism inhabited by parasites is as much a  habitat as a place on land such as a grove of trees or an aquatic locality  such as a small pond. �Microhabitat� refers to the conditions and organ�  isms in the immediate vicinity of a plant or animal.</p><p>habituation Reduction of an animal�s behavioral response to a stimu�  lus, as a result of a lack of reinforcement during continual exposure to the  stimulus. Habituation is usually considered a form of learning in which  behaviours not needed are eliminated. It may be separated from most other  forms of decreased response on the basis of permanence; the habituated  animal either does not resume its earlier reaction to the stimulus after a  period of no stimulus, or, if the normal reaction is resumed on reexpo�  sure to the stimulus, it wanes more quickly than before. Vital responses  (e.g., flight from a predator) cannot be truly habituated.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Habsburg &#x25BA; Hadrian's Wall I 823</p><p>Habsburg Vhaps-.borgX dynasty or Hapsburg dynasty Royal  German family, one of the chief dynasties of Europe from the 15th to the  20th century.

They also controlled Hungary and Bohe�  mia (1526-1918) and ruled Spain and the Spanish empire for almost two  centuries (1504-06, 1516-1700). One of the earliest Habsburgs to rise to  great power was Rudolf I, who became German king in 1273. Frederick  IV, the Habsburg king of Germany, was crowned Holy Roman emperor  as Frederick III in 1452, and Habsburgs continued to hold that title until  1806.

The Haggadah retells the story of Exodus, offering  commentaries that provide a religious philosophy of Jewish history and  supplying answers to the traditional questions asked by children at the  beginning of the Seder. More broadly, the term Haggadah can refer to the  part of rabbinical literature not concerned with the law (e.g., stories,  parables, legends, history, and astronomy).</p><p>Haggai Vhag-e-,1, 'hag-,I\ (fl. 6th century bc) One of the 12 Minor Proph�  ets of the Hebrew scriptures, traditional author of the book of Haggai.  (His prophecy is part of a larger book, The Twelve, in the Jewish canon.)  Born during the Babylonian Exile, he returned to Israel when it ended and  helped mobilize the Jewish community to rebuild the Temple of Jerusa�  lem. His book consists of four prophecies delivered in 521 bc. He attributes  the economic distress of the returned exiles to their delay in reconstruct�  ing the Temple and promises that the new house of God will be greater  than the first.</p><p>Haggard, Sir H(enry) Rider (b. June 22, 1856, Bradenham, Nor�  folk, Eng.�d. May 14, 1925, London) British novelist. After holding a  series of official posts in South Africa (1875-81), he began writing sto�  ries set in Africa. Of his 34 colourful adventure novels, the best-known  is King Solomon�s Mines (1885); others include She (1887), Allan Qua-  termain (1887), Cleopatra (1889), and Ayesha (1905). Also a farmer, he  wrote A Farmer�s Year (1899) and Rural England (2 vol., 1902), and he  was knighted in 1912 for his work on agricultural commissions.</p><p>Haggard, Merle (Ronald) (b.

After his release from San Quentin prison in 1960, he returned to Bakers�  field and became a professional musician. He was soon producing hit  recordings regularly, including �Mama Tried,� �The Bottle Let Me  Down,� �The Fightin� Side of Me,� �Okie from Muskogee� (controver�  sial for its apparent attack on hippies), and later hit duets with George  Jones and Willie Nelson.</p><p>Walter Hagen, 1936</p><p>hagfish Any of about 30 species of  primitive jawless fishes in two fami�  lies of the class Agnatha. The Myx-  inidae are found in every ocean; the  Eptatretidae are found everywhere  but the North Atlantic. Hagfishes are  eel-like, scaleless, and soft-skinned  and have paired thick barbels on the end of the snout. Species grow to  16-32 in. (40-80 cm) long. They have a cartilaginous skeleton. The mouth  is a slitlike, sucking opening with homy teeth. Found in cold seawater,  to depths of over 4,000 ft (1,200 m), they habitually lie buried in burrows  on soft bottoms.

It is the  masterpiece of Byzantine architecture. Designed under Justinian I by Anthe�  mius of Tralles and Isidorus of Miletus, the original building was com�  pleted in less than six years (ad 532-37). It combined a longitudinal  basilica and a centralized building in a wholly original manner, with a huge  main dome (rebuilt 563) supported on pendentives and semidomes on either  side. In plan it is almost square. There are three aisles separated by col�  umns with galleries above and great marble piers rising up to support the  dome.

Located 4 mi (6 km) from the North Sea, it is the  administrative capital of The Netherlands, home to its court and govern�  ment, though Amsterdam is the official capital. The counts of Holland built  a castle at The Hague in 1248. The complex now forms the Binnenhof in  the old quarter of the city, which became the seat of the Dutch govern�  ment in 1585. The city grew rapidly in the 19th and 20th centuries. A  centre of government, international law, and corporate administration,  most of its businesses are engaged in trade, banking, and insurance. The  International Court of Justice is housed in the Peace Palace (1913). The  city is filled with notable architecture, much of which survived despite  the heavy damage inflicted on the city during the German occupation in  World War II.</p><p>Hague Conventions Series of international agreements signed at The  Hague (1899, 1907). The first conference was requested by Russia to dis�  cuss rules to limit warfare and attempt arms limitations. Twenty-six coun�  tries attended and approved several proposed conventions, including  prohibition of the use of asphyxiating gases (not renewed in 1907) and  creation of a Permanent Court of Arbitration. The 1907 meeting, called  by Theodore Roosevelt, was attended by 44 countries and also had arms  limitation as a goal, which again went unmet. An agreement to reconvene  in eight years confirmed the principle that international conferences were  the best way to handle international problems. Though World War I pre�  vented the next meeting from taking place, the conferences influenced  creation of the League of Nations and the United Nations.

In 1938,  with Meitner and Fritz Strassmann (1902-80), he found the first chemi�  cal evidence of nuclear-fission products, created when they bombarded  uranium with neutrons. For his discovery of nuclear fission, Hahn was  awarded a 1944 Nobel Prize.

It is located in the  South China Sea, separated from  Guangdong province by a narrow  strait. For centuries part of Guang�  dong, Hainan became a separate province in 1988, the southernmost prov�  ince of China and the smallest. Its capital is Haikou. It was under Chinese  rule since the 2nd century bc but was not closely controlled until the Tang  dynasty (ad 618-907). Chinese began settling the island in the 16th� 17th  centuries, gradually forcing the indigenous peoples into the interior.  Hainan was occupied by the Japanese (1939^15), and it came under com�  munist control in 1950.

United with Flanders several times  from the 11th to the 13 th century, it was later ruled by the house of  Avesnes, the Wittelsbachs, the Burgundians, and finally the Habsburgs.  Gradually annexed to France in the 17th and 18th centuries, part of the  county stayed with France (now the Nord department ), and the rest passed  to The Netherlands in 1814 and to Belgium in 1831.

Established in 1874,  it developed commercially as a port and as the terminus of a railway. It  became a leading industrial centre, and after 1954 many new plants were  built there with aid given by Soviet-bloc countries and by China. It sus�  tained heavy damage from U.S. bombing during the Vietnam War but was  subsequently rebuilt.</p><p>hair Threadlike outgrowths of the skin. Babies shed a layer of downy,  slender hairs (lanugo) before or just after birth. The fine, short, unpig-  mented hairs (vellus) then grow. Starting at puberty, terminal hair, longer,  coarser, and more pigmented, develops in the armpits, crotch, sometimes  on parts of the trunk and limbs, and, in males, on the face. Scalp hair,  eyebrows, and eyelashes are different types. The number of scalp hairs,  which grow about 0.5 in. (13 mm) per month, averages 100,000-150,000.  The hair shaft (above the skin) is dead tissue, composed of keratin. Only  a few growing cells at the base of the root are alive. Hair is formed by  cell division at the base of the follicle (a tiny pocket in the skin), part of  a cycle of growing, resting, and falling out. Vellus lasts about four months,  scalp hairs three to five years.</p><p>hairstreak Any butterfly in the subfamily Theclinae (family Lycae-  nidae), sometimes known as gossamer-winged butterflies.

Rapid fliers,  hairstreaks usually have iridescent wings and are typically brown or gray  with delicate stripes on the bottoms of the wings. Larvae are short, broad,  and sluglike. Some species eat plants, many are cannibals, and still oth�</p><p>ers secrete honey dew, a sweet by-product of digestion that attracts ants.

Its longest river is the  Artibonite. The poorest country in the Americas, Haiti has a developing  market economy based in large part on agriculture and light industries; cof�  fee is the main cash crop. It is a multiparty republic with two legislative  houses; the chief of state is the president, and the head of government is the  prime minister. For early history, see Hispaniola. Haiti gained its indepen�  dence in 1804, after former slaves led by Toussaint-Louverture in the 1790s  and by Jean-Jacques Dessalines in 1803 rebelled against French rule. The  new republic encompassed the entire island of Hispaniola, but the eastern  portion of the island was restored to Spain in 1809. It was reunited under  Haitian Pres. Jean-Pierre Boyer (1818-43); after his overthrow the eastern  portion revolted and formed the Dominican Republic. Haiti�s government  was marked by instability, with frequent coups and assassinations. It was  occupied by the U.S. in 1915-34. In 1957 the dictator Francois ("Papa  Doc") Duvalier came to power. Despite economic decline and civil unrest,  Duvalier ruled until his death in 1971. He was succeeded by his son, Jean-  Claude (�Baby Doc�) Duvalier, who was forced into exile in 1986. Haiti�s  first free presidential elections, held in 1990, were won by Jean-Bertrand  Aristide. He was deposed by a military coup in 1991, after which tens of  thousands of Haitians attempted to flee to the U.S. in small boats. When the  military government stepped down in 1994, Aristide returned from exile  and resumed the presidency. His associate Rene Preval replaced him in  1995, and in 2000 Aristide reclaimed the presidency, only to be driven from  office and out of the country in 2004 as economic and political instability  continued to plague Haiti.</p><p>Haitink \'hl-tiqk\, Bernard (Johann Hermann) (b.

He lived in poverty at a time when many  priests sought advancement under the Tokugawa shogunate, and he  attracted a large following that provided a new foundation for Rinzai Zen.  Hakuin taught that direct knowledge of truth is open to all people and that  a moral life must follow from religious belief.

He developed procedures  for studying the physiology of  breathing and of the blood and devices for measuring hemoglobin and for  analyzing blood gas and mixtures of gases. He discovered that breathing  is regulated in large part by the effect of the amount of carbon dioxide in  the blood on the brain�s respiratory centre. He studied the effects of low  air pressure, investigated the action of gases in mine suffocations and  explosions (an important contribution to mine safety), and developed a  staged decompression method for ascent from deep-sea dives. He also  tried to clarify the philosophical basis of biology. He was the brother of  Richard Burdon Haldane and the father of J.B.S.

An advertising executive in Los Angeles (1949-68), he man�  aged several of the campaigns of Richard Nixon, including Nixon�s 1968  presidential campaign. Named White House chief of staff, he became  known as the �Iron Chancellor� for his efficient management of the White  House and his close control of access to the president. Along with John  D. Ehrlichman, he was one of Nixon�s closest advisers. He participated in  the cover-up of involvement by White House officials in the Watergate  break-in (see Watergate scandal) and helped carry out other �dirty tricks�  during the 1972 campaign. Forced to resign in 1973, he was tried and  convicted in 1975 for conspiracy, perjury, and obstruction of justice; he  served 18 months in prison.</p><p>Hale, George E(llery) (b.

In  1892 he joined the faculty of the University of Chicago and began orga�  nizing the Yerkes Observatory, of which he was director until 1904; there  he built the 40-in. (1-m) refracting telescope that remains the largest of its  type in the world. He established the Astrophysical Journal in 1895. In  1904 he organized the Mount Wilson Observatory and was its director until  1923. There he built solar apparatus of great power as well as the huge  60-in. (1.5-m) and 100-in. (2.5-m) reflecting telescopes. In 1928 he began  work on a 200-in. (5-m) reflecting telescope at Caltech�s Palomar Obser�  vatory; completed in 1948, it was named in his honour. As a researcher, he  is known particularly for his discovery of magnetic fields in sunspots.</p><p>Hale, John Parker (b. March 31, 1806, Rochester, N.H., U.S.�d.  Nov. 19, 1873, Dover, N.H.) U.S. politician and reformer. He served in  the U.S. House of Representatives (1843�45), where he achieved promi�  nence as an opponent of slavery. In the U.S. Senate (1847-53, 1855-65),  he sponsored a bill abolishing flogging in the navy. In 1852 he was the  unsuccessful presidential candidate of the Free Soil Party. He returned to  the Senate as a Republican and became a leader of that party. He later  served as U.S. minister to Spain (1865-69).</p><p>Hale, Sir Matthew (b. Nov. 1, 1609, Alderley, Gloucestershire,  Eng.�d. Dec. 25, 1676, Alderley) British legal scholar. Orphaned at age  5, he planned to become a minister but ultimately chose the study of law.  He defended Archbishop William Laud and other Royalists during the  English Civil Wars (1642-51). As a justice of the Court of Common Pleas  (1654-58) and a member of Parliament (1654-60), he played a major role  in reforming the legal system and promoting the restoration of Charles II.  He later became chief baron of the Exchequer (1660) and chief justice of  the King�s Bench (1671-76). One of the greatest scholars of the history  of English common law, he is best known for his History of the Pleas of  the Crown (published 1736).</p><p>Hale, Nathan (b. June 6, 1755, Coventry, Conn.�d. Sept. 22, 1776,  Manhattan Island, N.Y., U.S.) American Revolutionary officer. After  graduating from Yale University (1773), he became a schoolteacher. In  1775 he joined a Connecticut regiment and took part in the siege of Bos�  ton. Made a captain in 1776, he helped capture a British provision sloop  on Long Island. Volunteering for spy duty, he penetrated British lines but  was captured while returning and hanged without trial the next day at the  age of 21. His last words reportedly were, �I only regret that I have but  one life to lose for my country,� a remark similar to one made in Joseph  Addison�s play Cato.</p><p>Hale, Sarah Josepha orig.

She edited the Ladies� Magazine (1828-37) and then  Godey's Lady's Book (1837-77); as the first female magazine editor, she  shaped many of the attitudes and ideas of women of the period. Her books  include The Ladies� Wreath (1837), a collection of poetry by women that  sold widely; and Woman �s Record (1853). She is also remembered for her  verse �Mary Had a Little Lamb� (1830).</p><p>Hale-Bopp, Comet Comet discovered in 1994 by the amateur astrono�  mers Alan Hale and Thomas Bopp at a distance from the Sun of about  seven astronomical units, beyond Jupiter�s orbit and farther than any comet</p><p>detected before by amateurs. Astronomers estimated its nucleus to be  about 25 mi (40 km) in diameter, larger than most comets. At its closest  approach to the Sun in April 1997, it was one of the intrinsically bright�  est comets in several centuries, though not the brightest as seen from  Earth. The comet triggered the mass suicide near San Diego, Calif., U.S.,  in 1997 of 39 members of a religious cult known as Heaven's Gate, whose  leader maintained that they would be reincarnated in a spacecraft follow�  ing in the comet�s wake.</p><p>Haleakala National Park \,ha-la-a-ka-'la\ National park, eastern  Maui, Hawaii, U.S. Established in 1960, it occupies an area of 28,655  acres (11,597 hectares).

An interview with Malcolm X led to the best-selling Autobi�  ography of Malcolm X (1965; film, 1992). His greatest success, however,  was Roots (1976, special Pulitzer Prize), a history of seven generations  of his ancestors beginning with their enslavement. Adapted for television,  it became one of the most popular American television shows ever and  spurred great interest in genealogy, though Haley later admitted that the  saga was partly fictional.</p><p>Haley, Bill orig.

Haley  worked as a disc jockey and sang and played guitar for several country  music bands in the late 1940s, later forming his own band, the Saddlemen.  Marrying elements of country to rhythm and blues, he renamed his band  Bill Haley and His Comets and recorded some of rock�s earliest hits,  including �Shake Rattle and Roll� (1954) and �Rock Around the Clock�  (1955). He continued to tour as a nostalgia act into the 1970s.</p><p>Haley, Sir William (John) (b. May 24, 1901, Jersey, Channel  Islands�d. Sept. 6, 1987, Jersey) English journalist and editor.

He held the post of director of the Manchester  Guardian and Evening News before becoming director general of the BBC  (1944-52) and then editor of The Times of London (1952-66), the most  important and influential position in British journalism.</p><p>half-life Interval of time required for one-half of the atomic nuclei of a  radioactive sample to decay (change spontaneously into other nuclear  species by emitting particles and energy), or the time required for the  number of disintegrations per second of a radioactive material to decrease  by one-half. Half-lives are characteristic properties of the various unstable  atomic nuclei and the particular way in which they decay. Alpha decay and  beta decay are generally slower processes than gamma decay.</p><p>halftone process In printing, a technique of breaking up an image into  a series of dots to permit reproduction of the full tone range of a photo�  graph or artwork. It is traditionally done by placing a glass screen printed  with a tight grid of lines over the plate being exposed. The grid breaks  up the image into hundreds of tiny dots, each of which is read by the  camera as either black or white�or, in the case of colour art, as either a  single printing colour or white. The resulting image, called a halftone, is  then rephotographed for printing. Screens are made with a varying num�  ber of lines per inch, depending on the application; for newspapers the  range is about 80-120, whereas glossy magazines usually require 133�  175 lines per inch.</p><p>Haliburton, Thomas Chandler (b.

He moved to England in 1856 and  was a member of Parliament from 1859 until his death. He is best known  for creating the character Sam Slick, a Yankee clock peddler and cracker-  barrel philosopher whose escapades first appeared in the newspaper Nova  Scotian and were later published in The Clockmaker (1836, 1838, 1840)  and other volumes.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>halibut &#x25BA; Hall effect I 829</p><p>halibut Any of various flatfishes, especially the Atlantic and Pacific hal�  ibuts (genus Hippoglossus, family Pleuronectidae), both of which have  eyes and colour on the right side.

Located in modem Turkey on a  peninsula in the Aegean Sea, it became the capital of Caria (c. 370 bc)  under the Persian satrap Mausolus, who built a great wall, public build�  ings, and a secret dockyard and canal. His widow erected (c. 350 bc) a  great tomb (the Mausoleum) in his memory. It was one of the Seven Won�  ders of the ancient world, and its remains are now in the British Museum.  Halicarnassus was the birthplace of the Greek historian Herodotus. It came  under Roman rule in 129 bc, and in early Christian times was a bishop�  ric.

Located on Halifax Harbour, an inlet  of the Atlantic Ocean, it was settled  by the British in 1749 as a counter�  balance to French holdings at Cape  Breton. It served as a British army  and navy base until its defenses were  taken over by the Canadian govern�  ment in 1906. The city suffered from  a munitions-ship explosion in 1917  that killed nearly 2,000 people. Dur�  ing World Wars I and II, Halifax was  Canada�s most important naval base.</p><p>The city is Nova Scotia�s leading  commercial and industrial centre,  and its port is one of the busiest in  Canada. Its educational institutions  include Dalhousie University (1818);  historic buildings include St. Paul�s  Church (1750), Canada�s oldest  Protestant church.

After teaching at Johns Hopkins University, he helped establish  Clark University (1888) in Worcester, Mass., and worked there to shape  experimental psychology into a science. He is frequently regarded as the  founder of child psychology and educational psychology; he also did  much to direct the ideas of Charles Darwin and Sigmund Freud into the  psychological currents of his time. He founded several journals, includ�  ing the American Journal of Psychology, and he helped found the Ameri�  can Psychological Association, of which he was the first president.

In 1836 he was appointed state  geologist for the Geological Survey of New York; his studies culminated  in the massive Geology of New York (part 4, 1843), a classic in U.S. geol�  ogy that introduced the geosynclinal theory of mountain building. He was  state geologist of Iowa (1855�58) and of Wisconsin (1857-60). He served  as director of New York State�s Museum of Natural History (1871-98).

She won prizes for her novel Adam �s Breed  (1926), a plea for animal rights. She was condemned for writing openly  and sympathetically about lesbianism in The Well of Loneliness (1928),  one of the first lesbian novels in English. It was judged obscene and  banned in Britain; the ban was overturned on appeal after Hall�s death.  Most of her five other novels express her strong Christian beliefs.</p><p>hall church Type of church with side aisles approximately equal in  height to the nave, unlike the typical basilica.

From c. 895 he traveled extensively as a teacher and preacher,  making three pilgrimages to Mecca and gathering a large following. These  travels and his popularity alienated his Sufi masters, and his demands for  reform earned him the enmity of non-Sufi Muslims. Accused of foment�  ing rebellion and claiming to be divine, he was arrested, imprisoned (c.  911-922), and eventually crucified and tortured to death.</p><p>Halle \'ha-l3\ (an der Saale) City (pop., 2002 est.: 243,045), east-  central Germany.

In 1676 he set sail for the  South Atlantic with the intention of  compiling an accurate catalog of the  stars of the Southern Hemisphere.</p><p>His star catalogue (1678) recorded  the position of 341 stars. In 1684 he  met Isaac Newton at Cambridge,  which led to his prominent role (with  Robert Hooke and Christopher Wren)  in the development of Newton's law  of gravitation. Halley edited New�  ton�s Philosophiae Naturalis Prin-  cipia Mathematica, bringing it to  print in 1687. He produced the first  meteorological chart (1686, showing  the distribution of prevailing winds  in the world�s oceans) and magnetic  charts of the Atlantic and Pacific  (1701). In astronomy, he described  the parabolic orbits of 24 comets  observed in the years 1337-1698. He showed that three of these were so  similar that they must have been the same comet, and he accurately pre�  dicted its return in 1758 (see Halley's Comet).</p><p>Halley's Comet First comet whose return was predicted, proving that  at least some comets are members of the solar system. Edmond Halley  showed in 1705 that comets seen in 1531, 1607, and 1682 were really one  comet, and he predicted its return in 1758. Later calculations identified it  with the large, bright comet seen during the Norman Conquest (and  depicted in the Bayeux Tapestry) and with other comet sightings at inter�  vals of about 76 years, the first in 240 bc. The only easily seen comet that  returns in a single lifetime, it approached Earth twice in the 20th century  (1910, 1985-86). Its nucleus is roughly 9 mi (15 km) across.</p><p>hallmark Symbol stamped on an item of silver or gold to indicate that  it conforms to legal standards of purity. Hallmarking in Britain dates from  1300; no gold or silver could be sold until tested for purity and struck  with the king�s mark. A maker�s mark was introduced in 1363; at first a  symbol, such as a fish or key, it came to include or be replaced by ini�  tials. A �hallmark� was a mark made at Goldsmith�s Hall, London. In the  U.S., no hallmarks were initially required. In the late 18th and early 19th  century, local regulations were established in New York, Boston, Balti�  more, and elsewhere; makers� marks appeared and the words �coin� and  �sterling� were stamped on silver objects. In 1906 the use of the words  came under federal regulation. Hallmarks on gold, similar to those on sil�  ver, are also subject to federal regulation.</p><p>Halloween Holiday observed on October 31, the eve of All Saints' Day.  Its pagan origins can be traced to the Celtic festival of Samhain, celebrated  in ancient England and Ireland to mark the beginning of the Celtic new  year. The souls of the dead were supposed to revisit their homes on Sam�  hain eve, and witches, goblins, black cats, and ghosts were said to roam  abroad. The night was also thought to be the most favorable time for divi�  nations concerning marriage, luck, health, and death. The pagan obser�  vances influenced the Christian festival of All Hallows� Eve, celebrated  on the same date. The holiday was gradually secularized and was intro�  duced into the U.S. by the late 19th century. Still associated with evil  spirits and the supernatural, it is celebrated by children in costume who  gather candy by ringing doorbells and calling out �trick or treat,� �trick�  referring to the pranks and vandalism that are also part of the Halloween  tradition.</p><p>Hallstatt Vhal-,shtat,\ English \'h6l-,stat\ Site in upper Austria where  objects characteristic of the Early  Iron Age (from c. 1100 bc) were first  identified.

They combine readily with  most metals and nonmetals to form a variety of compounds and never  occur uncombined in nature. A radioactive element, astatine occurs natu�  rally in minute amounts as an intermediate decay product; it has no stable  nonradioactive isotopes. Halogen salts formed with metal atoms (halides)  are very stable; sodium chloride is the most familiar. The halogen lamp takes  its name from the halogens included in the gas within its tungsten-filament  bulb, added to prolong filament life and increase brightness.</p><p>halogen lamp or tungsten-halogen lamp Incandescent lamp  with a quartz bulb and a gas filling that includes a HALOGEN. It gives bril�  liant light from a compact unit. The halogen combines with the tungsten  evaporated from the hot filament to form a compound that is attracted  back to the filament, thus extending the filament�s life. The evaporated  tungsten is also prevented from condensing on the bulb and darkening it,  an effect that reduces the light output of ordinary incandescent lamps.

He  developed conduction anesthesia (1885) by experimenting with injecting  his own nerve trunks with cocaine, a substance to which he subsequently  became addicted (though later cured). At Johns Hopkins University he  established the first surgical school in the U.S. An early champion of  aseptic procedures, Halsted introduced the use of thin rubber gloves in  surgery (1890).

Incorporated into the  French Empire (1810-14), it became a member of the German Confedera�  tion as a free city in 1815. In World War II Allied firebombing killed some  55,000 people and devastated the city. It was rapidly rebuilt after the war.

In the American Revolu�  tion he joined the Continental Army  and showed conspicuous bravery at  the Battle of Trenton (see Battles of  Trenton and Princeton). He served as  aide-de-camp to Gen. George Wash�  ington (1777-81); fluent in French,  he became a liaison with French  commanders. After the war he prac�  ticed law in New York. At the Con�  tinental Congress, he argued for a  strong central government. As a del�  egate to the Annapolis Convention in  1786, he drafted the address that led  to the Constitutional Convention.</p><p>With James Madison and John Jay, he  wrote an influential series of essays,  later known as the Federalist papers, in  defense of the new Constitution and  republican government. Appointed  the first secretary of the treasury  (1789), Hamilton developed fiscal  policies designed to strengthen the  national government at the expense of the states. His proposal for a Bank  of the United States was opposed by Thomas Jefferson but adopted by Con�  gress in 1791. Differences between Hamilton and Jefferson over the pow�  ers of the national government and the country�s foreign policy led to the  rise of political parties; Hamilton became leader of the Federalist Party,  and Madison and Jefferson created the Democratic-Republican Party.  Hamilton favoured friendship with Britain and influenced Washington to  take a neutral stand toward the French Revolution. In 1796 he caused a  rift in the Federalist Party by opposing its nomination of John Adams for  president. In 1800 he tried to prevent Adams�s reelection, circulating a  private attack that Aaron Burr, long at odds with Hamilton, obtained and  published. When Jefferson and Burr both defeated Adams but received an  equal number of electoral votes, Hamilton helped persuade the Federal�  ists in the House of Representatives to choose Jefferson. In 1804 he  opposed Burr�s candidacy for governor of New York. This affront,  coupled with alleged remarks questioning Burr�s character, led Burr to  challenge Hamilton to a duel, in which Hamilton was mortally wounded.</p><p>11, 1755/57, Nevis, British West</p><p>f</p><p>Alexander Hamilton, detail of an oil  painting by John Trumbull; in the  National Gallery of Art, Washington,  D.C.</p><p>Hamilton, Edith (b.

He studied law but never practiced, prefering instead to  manage his family�s plantations in Mississippi and South Carolina. From  1852 to 1861 he served in the South Carolina legislature. In the American  Civil War he organized and led �Hampton�s Legion� of South Carolina  troops for the Confederate States of America and saw combat in many key  battles. He eventually served as second in command under Jeb Stuart.  After Stuart�s death, Hampton was promoted to major general and led the  cavalry (1864). After the war he sought reconciliation but opposed the  policies of Reconstruction. As governor of South Carolina (1876-79), he  led the fight to restore white supremacy. He later served in the U.S. Sen�  ate (1879-91).</p><p>Hampton Roads Channel in the U.S. through which the James, Eliza�  beth, and Nansemond rivers flow into Chesapeake Bay.

Pres. Abraham Lincoln agreed to meet with the Confederate vice president,  Alexander H. Stephens, to reach a peace settlement. Lincoln�s terms called  for a reunion of the nation, emancipation of the slaves, and disbanding  of Confederate troops. Since Stephens had been authorized to accept inde�  pendence only, no settlement was reached.</p><p>hamster Any of various stout Old World rodents (in the family  Muridae) with a short tail, soft fur,  and long cheek pouches for carrying  food. Hamsters are nocturnal and  generally live in burrows; they feed  on fruits, grain, and vegetables,  though some species also eat insects  and other small animals. The com�  mon hamster of Europe and western  Asia is 8-12 in. (20-30 cm) long,  without the 1-2.5-in. (3-6-cm) tail;  its coat is brown above and black  below, with white patches along each  side.

Feb. 19, 1952, near  Grimstad) Norwegian novelist, dra�  matist, and poet. Of peasant origin, he had almost no formal education.  His semiautobiographical first novel, Hunger (1890), about a starving  young writer, revealed his impulsive, lyrical style. It was followed by such  works as Mysteries (1892), Pan (1894), and Victoria (1898), with which  he established himself as a leader of the Neoromantic revolt against social  realism. Growth of the Soil (1917) and his many other novels express a  message of fierce individualism and back-to-nature philosophy. He won  the Nobel Prize for Literature in 1920. His antipathy to modem Western  culture led to his support of Nazi Germany during its wartime occupation  of Norway; he was imprisoned and tried after the war, and his reputation  was seriously damaged.</p><p>han Fief controlled by a daimyo, or territorial lord, during the Tokugawa  period (1603-1867) in Japan. Collectively, the han resembled a confed�  eration of principalities united under the Tokugawa shogunate. In 1869  the daimyo were requested to surrender their domains to the Meiji emperor;  in 1871 they were abolished and replaced by the present-day prefectures.</p><p>Han dynasty \'han\ (206 bc-ad 220) Second great Chinese imperial  dynasty. In contrast to the preceding Qin dynasty, the Han was a period  of cultural flowering. One of the greatest of the early histories, the Shiji  by Sima Qian, was composed, and the fu, a poetic form that became the  norm for creative writing, began to flourish. The Yuefu, or Music Bureau,  collected and recorded not only ceremonial chants but also the songs and  ballads of ordinary people. Lacquerware, first developed during the Shang  dynasty, reached a level of great mastery, and silk was woven for export</p><p>trade, which reached as far as Europe. Buddhism entered China during  the Han. Paper was invented, time was measured with water clocks and  sundials, and calendars were published frequently. So thoroughly did the  Han dynasty establish what was thereafter considered Chinese culture that  the Mandarin Chinese word for Chinese people is Han.</p><p>Han \'han\ River River, east-central China. A principal tributary of the  Yangtze River (Chang Jiang), it has a total length of about 950 mi (1,530  km). It rises in the mountains in southwestern Shaanxi province; known  by various names in its upper course, it becomes the Han at Hanzhong  and flows through a fertile basin some 60 mi (100 km) long and 12 mi  (19 km) wide, then cuts through a series of deep gorges and emerges into  the central Yangtze basin in Hubei province. Its lower course forms a dense  network of water transport covering the southern part of the North China  Plain.</p><p>Han Yongun Vhan-'yoq-'unV or Manhae (b. 1879, Korea�d. 1944,  Korea) Korean poet and religious and political leader. After participating  in the failed Tonghak Uprising, he fled to Mount Solok and studied Bud�  dhism. He became a priest in 1905 and set out to restore and nationalize  Buddhism in Korea. In 1910, when Korea came under Japanese rule, he  joined the independence movement. He helped draft a Korean Declara�  tion of Independence in 1919 and was arrested and jailed for three years.  In 1927 he led in the establishment of the Singanhoe society, a united  national independence front. His best-known work is a volume of poetry,  The Silence of the Lover.</p><p>Han Yu or Han Yu Vhan-'yuA (b. 768, Henan province, China�d. 824,  Chang�an) Chinese poet and prose  writer, the first proponent of Neo-  Confucianism. An orphan, he joined  the Chinese bureaucracy and served  in several high government posts. He  attacked Daoism and Buddhism, which  were then at the height of their influ�  ence, and sought to restore Confu�  cianism to its former status. He  revived interest in the writings of  Mencius and other neglected Confu-  cian classics. His own works were  written in a simple prose style unlike  the elaborate manner popular at the  time, and he became known as the  �Prince of Letters.�</p><p>Hancock, Herbie orig.

Oct. 8, 1793,  Quincy, Mass., U.S.) American Revolutionary leader. He entered the mer�  cantile business of his wealthy uncle in Boston in 1754. His adherence  to the patriot cause dates from the Stamp Act, which, as a leading mer�  chant, he protested. In 1769, soon after the British seized one of his ships,  he was elected to the Massachusetts legislature, and he chaired the Bos�  ton town committee formed after the Boston Massacre. He became presi�  dent of the provincial congress (1774-75), and he and Samuel Adams led  the Massachusetts Patriots. In 1775 both were forced to flee from British  troops sent to arrest them for treason. Hancock was a member of the Con�  tinental Congress (1775-80), serving as its president (1775-77); the bold  flourish with which he signed the Declaration of Independence has made  his name synonymous with �signature.� As governor of Massachusetts  (1780-85, 1787�93), he presided over the state�s ratification of the Con�  stitution in 1788.</p><p>Hancock, Winfield Scott (b.

Appointed a brigadier general of volunteers at the start of the American  Civil War, he became a corps commander in the Army of the Potomac  (1863-65) and served with distinction at the Battle of Gettysburg. After  the war he commanded the military division of Louisiana and Texas. For  his insistence that the region�s civil authorities be maintained in their  �natural and rightful dominion,� he won the support of Democrats, who  nominated him for president in 1880. He lost the election to James Garfield.</p><p>hand End part of the arm, consisting of the wrist joint, palm, thumb, and  fingers. The hand has great mobility and flexibility to carry out precise  movements. Bipedal locomotion in humans frees the hands for grasping  and manipulation.

Dexterity in the hands and  increased brain size are believed to have evolved together in humans.</p><p>Hand, (Billings) Learned (b. Jan. 27, 1872, Albany, N.Y., U.S.�d.  Aug. 18, 1961, New York, N.Y.) U.S. jurist. He attended Harvard Uni�  versity, where he studied philosophy (under William James, Josiah Royce,  and George Santayana) and law; thereafter he practiced law in Albany  and New York City. In 1909 he was appointed a federal district judge, and  in 1924 he was elevated to the U.S. Circuit Court of Appeals, becoming  chief judge in 1939. He sat in many cases after his official retirement in  1951. His 52-year tenure on the federal bench (from 1909 to his death in  1961) represents a record. Several of his decisions, especially in the anti�  trust suit known as the Alcoa case (1945) and in a 1950 case involving  charges of communist conspiracy, are considered landmarks. Although he  never reached the Supreme Court of the United States, his reputation sur�  passes that of all but a few who have sat there.</p><p>handball Any of a variety games in which a small rubber ball is struck  against a wall with the hand or fist. It can be played in a three- or four-  walled court or against a single wall by two or four players (in singles or  doubles games, respectively). The object is to make the ball rebound off  the wall so that it cannot be returned by the opponent. The game runs to  21 points. Handball games were played in ancient Rome and later (as  pelota) in Spain and France. Modern handball developed in Ireland, where  it is still popular. It was played widely among late-19th-century Irish  immigrants in New York City, whence it eventually spread around North  America.</p><p>Handel, George Frideric orig.</p><p>Feb. 23, 1685, Halle,</p><p>Brandenburg�d. April 14, 1759,</p><p>London, Eng.) German-born British  composer. Born to a barber-surgeon  in Halle, he showed a marked gift for  music and studied organ, violin, and  composition. He moved to Hamburg  in 1703 and played in the opera  orchestra under Reinhard Keiser  (1674-1739), and his first opera was  produced there in 1705. A Medici  prince invited him to Florence; there  and in Rome, patronized by cardinals  and nobility, he wrote oratorios, can�  tatas, and more operas. Hired as  kapellmeister by the elector at Han�  nover (1710), he asked permission to  visit London before assuming his  responsibilities. There his opera  Rinaldo (1711) immediately made  his name; forsaking Hannover, he  remained in England for the rest of  his life. In 1714 the German elector  was made George I of England; any  annoyance at Handel�s defection dissipated, and the king became one of  his patrons. Handel was appointed musical director of the new Royal  Academy of Music, an opera house that thrived until the public taste  shifted away from Italian opera. In 1732 he revised his oratorio Esther  for a public performance, the first public oratorio performance in England.  Its success was followed by many more English-language oratorios,  including his great Messiah (1741); by this time he had made oratorio and  large-scale choral works the most popular musical forms in England. He  was renowned as virtually the greatest organist and harpsichordist in the  world. Handel wrote about 45 Italian operas, including Giulio Cesare</p><p>(1723), Orlando (1733), and Alcina (1735). His oratorios include Israel  in Egypt (1739), Saul (1739), and Jephtha (1752). His church music  includes the Chandos Anthems (1718) and Coronation Anthems (1727).  Though the bulk of his music was vocal, he composed a number of great  orchestral works, such as the famous Water Music (1717) and Royal Fire�  works Music (1749).</p><p>handicap In sports and games, a method of offsetting the varying abili�  ties or characteristics of competitors in order to equalize their chances of  winning. Handicapping takes many, often complicated, forms. In horse  racing, a track official known as the handicapper may assign weights to  horses according to their speed in previous performances; the presumed  fastest horse must carry the most weight. In golf, two unequal players  may have a close match by allowing the poorer player a handicap, a cer�  tain number of uncounted strokes based on earlier performances. In sail�  boat racing, dissimilar boats compete under handicapping formulas that  add time to the faster boats� actual elapsed time for a race; thus, the win�  ner of a race may not be the first to finish but rather the boat that per�  forms best in relation to its design.

He earned an  early reputation as a member of the avant-garde with plays such as Offend�  ing the Audience (1966), in which actors analyze the nature of theatre and  alternately insult the audience and praise its �performance,� and Kaspar  (1968). His novels, mostly ultraobjective, deadpan accounts of characters  in extreme states of mind, include The Goalie�s Anxiety at the Penalty  Kick (1970) and The Left-Handed Woman (1976). A dominant theme of  his works is the deadening effects and underlying irrationality of ordinary  language, everyday reality, and rational order.</p><p>Handsome Lake See Ganioda'yo</p><p>Handy, W(illiam) C(hristopher) (b.

Handy worked as a soloist and conductor with  several bands around the turn of the century and became active as a music  publisher in Memphis (1908) and later New York (1918). Handy�s com�  positions, including �St. Louis Blues,� �Beale Street Blues,� and �Mem�  phis Blues,� became favourites of singers and instrumentalists in the  1920s, helping to codify the blues as a framework within which to impro�  vise.</p><p>Hanfeizi Vhan-'fa-'tsoN or Han-fei-tzu Vhan-'fa-'dziA (d. 233 bc,  China) Greatest of China�s legalist philosophers. Much about his life is  unknown; it ended when he was sent on a diplomatic mission to the court  of the first Qin emperor, who had admired his writings; he was impris�  oned and forced to drink poison. His works are collected in the Hanfeizi,  presumably compiled after his death. In 55 sections of varying lengths, it  presents a synthesis of legal theories up to his time. To Hanfeizi it was  axiomatic that political institutions must change with changing historical  circumstances and must be adapted to the prevailing pattern of human  behaviour, which is determined not by moral sentiments but by economic  conditions. Rulers should not try to make people good but only to restrain  them from doing evil.</p><p>hang gliding Sport of flying in unpowered aircraft that are light enough  to be carried by the pilot. Takeoff is usually achieved by launching into  the air from a cliff or hill. Hang gliders were developed by the pioneers  of practical flight. In Germany, starting in 1891, Otto Lilienthal made  several thousand flights before a fatal gliding accident in 1896. In the U.S.  collaboration between Augustus Herring and Octave Chanute resulted in  successful flights of a biplane hang glider in 1896. Modern hang gliding  emerged toward the end of the 1960s. In the early 1960s enthusiasts in  California were gliding down coastal dunes on homebuilt delta-shaped  wings they had adapted from kite designs developed by Francis and Ger�  trude Rogallo. The Rogallos� kites had attracted attention because of  NASA�s interest in using them for spacecraft retrieval. By the early 1970s  the sport had spread throughout the U.S. and into Europe. World cham�  pionships in hang gliding have been held and records kept since 1975.</p><p>Hangul Alphabetic system used for writing the Korean language.

As Lin�an,  it was the capital of the Song dynasty c. ad 1126-1279. A prosperous cen�  tre of commerce with an estimated population then of 1-1.5 million, it  was visited in the late 13th century by the Italian traveler Marco Polo,  who called it Kinsai. Its importance as a port decreased as the bay silted  up, but it remained a commercial centre and was opened to foreign trade  in 1896. In addition to its cultural importance, it is also the centre for an  industrial area.</p><p>haniwa \'ha-ne-,wa\ Terra-cotta cylinders and sculptures arranged on  and around Japanese tombs during the Tumulus period (c. ad 250-552).

He became a businessman in Cleveland,  Ohio, with interests in banking, coal and iron, transportation, and pub�  lishing. Convinced that the interests of big business would best be served  by the Republican Party, he began in 1880 to gather support among indus�  trialists for its candidates. In 1892 he helped William McKinley secure the  Ohio governorship. For McKinley�s 1896 presidential campaign Hanna  helped the Republicans raise an unprecedented $3.5 million, enough to  overwhelm the grassroots campaign of William Jennings Bryan.

Taken  to Spain by his father, the Carthaginian general Hamilcar Barca (d. 229/  228 bc), he was sworn to eternal enmity with Rome. After the death of  his father and brother-in-law, he took charge of Carthage�s army in Spain  (221). He secured Spain, then crossed the Ebro River into Roman terri�  tory and entered Gaul. He marched over the Alps into Italy; encumbered  by elephants and horses, he was beset by Gallic tribes, harsh winter  weather, and defection of his Spanish troops. He defeated Gaius Flaminius</p><p>but was severely harassed by Quintus Fabius Maximus Cunctator. In 216  he won the Battle of Cannae. In 203 he left for northern Africa to help  Carthage fend off Scipio Africanus the Elder�s forces. He lost decisively to  Scipio�s ally, Masinissa, at the Battle of Zama but escaped. He headed the  Carthaginian government (c. 202-195); forced to flee, he sought refuge  with Antiochus III, whose fleet he commanded against Rome, with disas�  trous results. After the Battle of Magnesia (190) the Romans demanded  he be handed over; he eluded them until, seeing no escape, he took poi�  son.</p><p>Hannover Mia-'no-forN English Hanover Vha-.no-vorX City (pop.,  2002 est.: city, 516,415; metro, area, 996,586), capital of Lower Saxony  state, northwestern Germany.

It was the main  capital of Vietnam until 1802, when the Nguyen dynasty transferred the  capital south to Hue. Under French rule Hanoi again became an impor�  tant administrative centre, and in 1902 it was made the capital of French  Indochina. It became the capital of North Vietnam after the French defeat  in 1954. During the Vietnam War many of its monuments and palaces were  destroyed by U.S. bombing.

It was  descended from George Louis, elector of Hanover, who succeeded to the  British crown as George I in 1714. The dynasty also provided the mon-  archs George II, George III, George IV, William IV, and Victoria. By the Act  of Settlement (1701) the crown was to go to Anne (of the house of Stuart)  and then, if she lacked issue, to Sophia (1665-1714), electress of Hanover  (granddaughter of James I) and her descendants.

The league dominated commercial activity in northern Europe  from the 13th to the 15th century. It protected transport of goods by quell�  ing pirates and brigands and fostered safe navigation by building light�  houses. Most important, it sought to organize and control trade by winning  commercial privileges and monopolies and by establishing trading bases  overseas. In extreme cases its members resorted to warfare, as when they  raised an armed force that defeated the Danes in 1368 and confirmed the  league�s supremacy in the Baltic Sea. Over 150 towns were at some point  associated with the league, including Bremen, Hamburg, and Liibeck.</p><p>Hansen disease See leprosy</p><p>Hanson, Howard (Harold) (b.

Carried by rodents, they spread to  humans directly or by inhalation but apparently are not transmitted from  one person to another. An outbreak in the 1990s in the southwestern U.S.  caused a mysterious, often fatal, flulike illness with rapid respiratory fail�  ure in previously healthy adults. The culprit was a hantavirus type car�  ried by mice and not previously associated with human illness in the U.S.</p><p>Hanukkah Vha-no-ko, 'ka-no-k3\ In Judaism, a holiday celebrating the  rededication of the Second Temple of Jerusalem in 164 bc, after its des�  ecration three years earlier by order of Antiochus IV Epiphanes. The Mac�  cabees recaptured Jerusalem and reconsecrated the Temple after leading a  successful revolt against Syrian rule. The lighting of the menorah recalls  the story that a one-day supply of oil burned miraculously in the Temple  for eight days until new oil could be obtained. Sometimes called the Feast  of Dedication or Feast of Lights, it is celebrated for eight days in Decem�  ber, during which the ceremonial candles are lit and children play games  and receive gifts. Originally a minor holiday, it has become more lavishly  celebrated as a result of its proximity to Christmas.</p><p>Hanuman Vho-nu-.man, .ho-nu-'maM Monkey god of Hindu mythol�  ogy, a central figure in the Ramayana. He was a guardian spirit, the off�  spring of a nymph and the wind god. His great heroic exploit was  recovering Rama�s wife, Sita, from captivity by the demon Ravana. Hanu�  man also flew to the Himalayas and carried back a mountain of medici�  nal herbs to cure Rama�s grievously wounded brother Laksmana.  Worshiped in the form of a monkey, he is an important deity because of  his strength and his faithfulness to Rama.</p><p>haplite See aplite  haploidy See ploidy</p><p>Hapsburg dynasty See Habsburg dynasty</p><p>Hara Kei \'ha-ra-'ka\ or Hara Takashi \'ta-ka-she\ (b.

Located on the Songhua River  in the centre of Manchuria, it grew with the arrival of the Chinese East�  ern Railway, built by the Russians in the late 19th century. A Russian  military base during the Russo-Japanese War, it was a haven for Russian  refugees after the Russian Revolution of 1917 and had the largest Russian  population of any city outside the Soviet Union. Chinese communist  forces took the city in 1946 and from it directed their conquest of Man�  churia. Since 1949 it has become the chief industrial base of northeast�  ern China, and it is a shipping centre for agricultural products.</p><p>harbour seal Nonmigratory, earless seal ( Phoca vitulina ) found  throughout the Northern Hemisphere. Harbour seals are whitish or gray�  ish at birth, generally gray with black spots as adults. The adult male may  reach a length of about 6 ft (1.8 m) and a weight of almost 300 lb (130  kg); the female is somewhat smaller. Found along coastlines and in a few  freshwater lakes in Canada and Alaska, the harbour seal is a gregarious  animal that feeds on fish, squid, and crustaceans. It is of little economic  value and in some areas is considered a nuisance by fishermen.</p><p>Harburg, E(dgar) Y(ipsel) orig. Isidore Hochberg (b. April 8,  1896/98, New York, N.Y., U.S.�d.

When his electrical-  appliance business went bankrupt in 1929, he devoted himself to song�  writing for Broadway, composing songs such as the Depression anthem  �Brother, Can You Spare a Dime?� (with Jay Gorney). From 1935 Har�  burg and Harold Arlen wrote songs for many films, notably The Wizard  of Oz (1939). Blacklisted from films for his political views, Harburg  returned to Broadway to write musicals, notably Finian�s Rainbow (1947;  with Burton Lane). Among his best-known songs are �April in Paris,�  �It�s Only a Paper Moon,� and �Over the Rainbow.�</p><p>hard coal See anthracite</p><p>hard disk Magnetic storage medium for a microcomputer. Hard disks  are flat, circular� plates made of aluminum or glass and coated with a mag�  netic material. Hard disks for personal computers can store up to several  gigabytes (billions of bytes) of information. Data are stored on their sur�  faces in concentric tracks. A small electromagnet, called a magnetic head,  writes a binary digit (1 or 0) by magnetizing tiny spots on the spinning  disk in different directions and reads digits by detecting the magnetiza�  tion direction of the spots. A computer�s hard drive is a device consisting  of several hard disks, read/write heads, a drive motor to spin the disks,  and a small amount of circuitry, all sealed in a metal case to protect the  disks from dust. In addition to referring to the disks themselves, the term  hard disk is also used to refer to the whole hard drive.</p><p>hard water Water that contains mineral salts of calcium and magne�  sium, principally as bicarbonates, chlorides, and sulfates, and sometimes  iron. Hardness caused by calcium bicarbonate is known as temporary,  because boiling converts the bicarbonate to the insoluble carbonate; hard�  ness from the other salts is called permanent. The calcium and magne�  sium in hard waters form a hard, adherent scale on boiler plates, increasing  fuel consumption and leading to deterioration through overheating. Home  water softeners consist of tanks containing zeolite minerals or ion-  exchange resins, which contain sodium ions that change places with the  calcium and magnesium.</p><p>Hardanger Fjord Miar-'daq-or-.fyordV Fjord, southwestern Norway.

He won the abiding trust of Frederick Will�  iam III in 1798 and served as foreign minister (1804-06). He was forced  to withdraw from political life, at Napoleon�s behest, after Prussia�s col�  lapse in the war of 1806-07 against France. When Prussia was faced with  insolvency and could not pay war indemnities in 1810, Napoleon agreed  to Hardenberg�s reinstatement, and he became prime minister with full  powers. He continued the domestic reforms introduced by Karl, imperial  baron vom und zum Stein, and liberalized financial, economic, and agri�  cultural policies. In foreign affairs he exchanged Prussia�s alliance with  France for an alliance with Russia in 1813, and in 1814-15 he represented  Prussia at the peace negotiations in Paris and Vienna.</p><p>hardening In metallurgy, an increase in hardness of a metal induced,  deliberately or accidentally, by hammering, rolling, drawing (see wire  drawing), or other physical processes. The first few deformations imposed  by such treatment weaken the metal, but because of the crystalline struc�  ture of metal its strength increases with continued deformations. Crystals  slip against each other; but, because of the complexity of the crystal  structure, the more such slips are multiplied, the more they tend to place  obstacles in the way of further slippage, as the various dislocation lines  crisscross each other.

In 1906 he became the first leader of  the Labour Party in the House of Commons. A pacifist, he sought unsuc�  cessfully to bind the Second International to declaring a general strike in  all countries in the event of war.

He  served successively as state senator  (1899-1902), lieutenant governor  (1903-04), and U.S. senator (1915�</p><p>21), supporting conservative poli�  cies. At the deadlocked 1920  Republican presidential convention,  he was chosen as the compromise  candidate. Pledging a �return to nor�  malcy� after World War I, he  defeated James Cox with more than  60% of the popular vote, the largest  margin to that time. On his recom�  mendation, Congress established a  budget system for the federal gov�  ernment, passed a high protective  tariff, revised wartime taxes, and restricted immigration. His administra�  tion convened the Washington Conference (1921-22). His ill-advised  cabinet appointments, including Albert Fall as secretary of the interior, led  to the Teapot Dome scandal and earned his administration a reputation for  coiTuption. After a vacation in Alaska in mid-June 1923, he arrived in San</p><p>Francisco reportedly suffering from food poisoning and other ailments;  he died there under unclear circumstances.

Son  of a country stonemason and builder, he practiced architecture before  beginning to write poetry, then prose. Many of his novels, beginning with  his second, Under the Greenwood Tree (1872), are set in the imaginary  county of Wessex. Far from the Madding Crowd (1874), his first success,  was followed by The Return of the Native (1878), The Mayor of Caster-  bridge (1886), Tess of the D�Urbervilles (1891), and Jude the Obscure  (1895), all expressing his stoical pessimism and his sense of the inevi�  table tragedy of life. Their continuing popularity (many have been filmed)  owes much to their richly varied yet accessible style and their combina�  tion of romantic plots with convincingly presented characters. Hardy�s  works were increasingly at odds with Victorian morality, and public indig�  nation at Jude so disgusted him that he wrote no more novels. He returned  to poetry with Wessex Poems (1898), Poems of the Past and the Present  (1901), and The Dynasts (1910), a huge poetic drama of the Napoleonic  Wars.</p><p>Hardy-Weinberg law Equation that describes genetic balance  within a population.

Forces that can disturb this  natural balance are selection, mutation, gene flow, and natural selection.  Certain gene-controlled traits are selected for or against by the partners  involved.

The organization  claims a lineage of spiritual masters  dating back to Caitanya (1485-  1534?), whom it regards as an incar�  nation of Krishna. Hare Krishna  became popular in the U.S. and  Europe among young people of the  1960s and �70s counterculture, who  often appeared in public places  dressed in saffron robes, chanting,  dancing, and asking for contribu�  tions. Members of the group are vegetarians. They renounce alcohol and  drugs and chant several hours every day. Peace and joy are to be gained  by surrendering to Krishna. Since the founder�s death in 1977, the com�  munes in which many members live have been governed by an interna�  tional commission.

Through extension it has come to refer generally to the  mandatory seclusion of women from the outside world. Institutions simi�  lar to the harem existed in the pre-Islamic civilizations of the Middle East;  in the courts of pre-Islamic Assyria, Persia, and Egypt, they were often  the loci of political intrigues involving rival court factions. Large harems  for wives (and often for concubines) were common in wealthy Middle  Eastern households until the 20th century. From the 15th to the 20th cen�  tury, the great harem, termed the seraglio, of the sultans of the Ottoman  Empire housed several hundred women. In Iran�and in parts of Central  and South Asia influenced by Persian culture�the institution of seclusion  has traditionally been known as purdah.

He  became Guru after the execution of his father. Guru Arjan, by the Mughal  rulers of India. Until his time, Sikhism had been a passive and peace-loving  religion, but Hargobind gave it a strong military character in response to  the enmity of the Mughals. He created an army, fortified cities, and built  a defensive encampment near the holy city of Amritsar. For this he was  jailed for 12 years by the emperor.

Contemplative by temperament, he shunned military  obligations and weakened the Sikhs in their struggle against India�s  Mughal emperors. He made a political blunder by helping the brother of  the emperor Aurangzeb foment a rebellion.

In 1877 he was appointed to the  Supreme Court of the United States by Pres. Rutherford B. Hayes. During his  tenure, which lasted to his death in 1911, he became one of the most  forceful dissenters in the court�s history and its outstanding liberal jus�  tice. His best-known dissenting opinions, such as those in Plessy v. Fergu�  son (1896) and the Civil Rights cases (1883), favoured the rights of  blacks. He also issued famous dissents in favour of the federal income tax  (1895) and opposing monopolies in cases arising under the Sherman Anti�  trust Act of 1890.

Successive notes of  the diatonic (seven-note) scale are obtained by alternately blowing and  sucking; the tongue covers channels not required. In chromatic (12-note  scale) models, a finger-operated stop  selects either of two sets of reeds  tuned a semitone apart. The har�  monica was invented in 1821 by  Friedrich Buschmann (1805-64) of  Berlin, who borrowed the basic prin�  ciple from the Chinese sheng.

In a narrower sense harmony refers to the extensively developed  system of chords and the rules that govern relations between them in  Western music. Harmony has always existed as the �vertical� (the rela�  tionship between simultaneous melodic lines) aspect of older music that  is primarily contrapuntal; the rules of counterpoint are intended to con�  trol consonance and dissonance, which are fundamental aspects of har�  mony. However, the sense of harmony as dominating the individual  contrapuntal lines followed from the invention of the continuo c. 1600;  the bass line became the generating force upon which harmonies were  built. This approach was formalized in the 18th century in a treatise by  Jean-Philippe Rameau, who argued that all harmony is based on the �root�  or fundamental note of a chord. Tonality is principally a harmonic con�  cept and is based not only on a seven-note scale of a given key but on a  set of harmonic relations and progressions based on triads (three-note  chords) drawn from the scale.</p><p>Harmsworth, Alfred See Viscount Northcliffe</p><p>harness racing Horse-racing sport. In harness racing, Standardbred  horses are harnessed to lightweight, two-wheeled, bodiless (seat-only)  vehicles known as sulkies. The sport�s origins date to ancient chariot  races. Today two types of horses are used, trotters and pacers. The former  employ a gait in which the legs move in diagonal pairs, the latter a gait  in which the legs move in lateral pairs. Since the establishment of pari�  mutuel racing under lights in the 1940s, the sport has grown tremendously  in popularity.</p><p>Harnett, William (Michael) (b. Aug. 10, 1848, Clonakilty, Ire.�d.  Oct. 29, 1892, New York, N.Y., U.S.) Irish-born U.S. still-life painter.  Brought to Philadelphia as a child, he was trained as an engraver and soon  developed outstanding skill in trompe l'oeil painting. While traveling in  Europe he painted his best-known work, After the Hunt (1885). In 1886  he settled in New York City. His work, popular with the public, was gen�  erally dismissed by critics. After a long period of disrepute, his works  again were appreciated and sought after when mid-20th-century critics  recognized Harnett�s outstanding skill at abstract composition.</p><p>Harold I known as Harold Harefoot (d.

Small, primitive  harps date back to at least 3000 bc in the ancient Mediterranean and  Middle East. In Europe they became particularly important in Celtic soci�  eties. The large modern orchestral harp emerged in the 18th century. It  has 47 strings and a range of almost seven octaves. It plays the entire  chromatic (12-note) scale by means of seven pedals, each of which can  alter the pitch of a note (in all octaves) by two semitones through tight�  ening or relaxing the strings by turning a forklike projection against it; it  is thus known as the double-action harp. Its massive resonator permits  considerable volume of tone.

Adults are about 6 ft (1.8 m) long and 400 lb (180  kg). Strong swimmers, harp seals feed on fish and crustaceans and spend  much of the year at sea. They breed near Newfoundland, Can., and in the  Greenland and White seas. Until two weeks old, the pups bear a fluffy  white coat highly valued by the fur trade; public indignation over hunt�  ing methods (including clubbing) has led to increased regulation and  supervision of sealing activities in the Newfoundland area.</p><p>Harper, Stephen in full Stephen Joseph Harper (b.

The two oldest broth�  ers, James (1795-1869) and John (1797-1875) established J. &amp; J. Harper  in 1817; their siblings Joseph (1801-70) and Fletcher (1806-77) joined  in 1823 and 1825. The firm took the name Harper &amp; Brothers in 1833.  The company began publishing periodicals in 1850 with Harper�s New  Monthly Magazine (see Harper's Magazine), which was followed by Harp�  er�s Weekly (1857) and Harper�s Bazaar (1867). In 1900 the business  passed out of family hands.

By 1865 it had become the  most successful periodical in the U.S. In the 1920s its format changed to  that of a forum on public affairs, balanced with short stories. Financial  problems began in the 1960s, and in 1980 its demise was averted by grants</p><p>from a philanthropic organization, the MacArthur Foundation.

The  latter consists of plectra made of  quill (or sometimes leather) mounted  on vertical wooden jacks that are  activated by the keys. A cloth  damper touches the string when the  player releases the key. It often has  two parallel keyboards (or manuals)  and generally has two or more sets  of strings, each of which produces  different tone qualities; these permit  the simultaneous sounding of pitches  an octave higher or lower than the  note struck. The notes� loudness is  not affected by the power with which  the keys are struck, and there is no  way to sustain a note after the key is  released. Primitive harpsichords  existed by the mid-15th century. In  the 17th�18th centuries the harpsichord became a very important solo,  accompanimental, and ensemble instrument. From c. 1750 the pianoforte,  with its greater dynamic capacity, began to displace it, and by 1820 the  harpsichord had largely vanished. It was revived in the late 19th century  by scholars, performers, and instrument builders.</p><p>Harpy In Greek and Roman mythology, a bird of prey with a woman�s  face. Often depicted on tombs. Harpies may originally have been con�  ceived of as ghosts. In early Greek literature, including the writings of  Homer and Hesiod, they were wind spirits and were not represented as ugly  or repellent. In the legend of Jason and the Argonauts, however, the Har�  pies were hideous, foul-smelling birds with the faces of women, sent to  punish King Phineus of Thrace by defiling his food; they were frightened  away by the sons of Boreas.</p><p>harrier Any of about 11 species of hawks (subfamily Circinae; family  Accipitridae) that are plain-looking, long-legged, long-tailed, and slender.

In 1898 he organized a syndicate to acquire the bank�  rupt Union Pacific Railroad Co., which he soon brought into prosperity.  Using unpopular business methods, he acquired several other lines, nota�  bly the Southern Pacific. His abortive 1901 contest with James J. Hill for  control of the Northern Pacific led to one of Wall Street�s most serious  financial crises. The railway trust Harriman formed with J.P. Morgan was  dissolved by the U.S. Supreme Court in 1904. His son W. Averell Har�  riman joined the company in 1915 (chairman 1932-46) and was active  in politics; he was elected governor of New York (1954-58) and served  the U.S. government as a representative and diplomat in Europe, the Far  East, and the Soviet Union.</p><p>Harriman, W(illiam) Averell (b.

His works, which helped cre�  ate the local-colour school in Ameri�  can fiction, include the short stories  �The Luck of Roaring Camp� (1868)  and �The Outcasts of Poker Flat�</p><p>(1869), the poem �The Heathen  Chinee� (1870), and the play Ah Sin  (1877; with Mark Twain). In an era  when the West was a popular subject,  these works made him internation�  ally famous. His writing slumped in  the 1870s, and he accepted consul�  ships in Europe, never returning to  the U.S.</p><p>hartebeest Vhar-t3-,best\ Either  of two species of swift, slender ante�  lope (genus Alcelaphus) found in  herds on open plains and scrublands  of sub-Saharan Africa. They often  mingle with herds of other antelope  or zebras. Hartebeests stand about 4  ft (1.2 m) tall at the shoulder, and the  back slopes downward from heavy  forequarters to narrow hindquarters.</p><p>The long face is accentuated, in both  sexes, by ringed, lyre-shaped horns  united at the base. The red hartebeest  is pale reddish brown with a lighter  rump.

The Fundamental Orders of Connecticut, which later served as a  model for the U.S. Constitution, were adopted (1639) in Hartford. The  city�s insurance industry, its major business, dates from 1794, when the  first Hartford fire insurance policy was issued. The statehouse (1796) was  designed by Charles Bulfinch. Institutions of higher learning include Trin�  ity College. The birthplace of J.P. Morgan, Hartford was also the home of  Harriet Beecher Stowe and Mark Twain, whose houses are preserved.</p><p>Hartford Convention (Dec. 5, 1814-Jan. 5, 1815) Secret meeting of  Federalist Party delegates from New England states who opposed the War  of 1812. It adopted a strong states 7 -rights position in opposition to the  mercantile policies of Pres. James Madison and the Embargo Act of 1807  and other measures that prohibited trade with Britain and France. News  of the signing of the Treaty of Ghent on Dec. 24, 1814, which ended the  war, discredited the nascent separatist movement at the convention and  weakened Federalist influence.</p><p>Hartley, Marsden (b. Jan. 4, 1877, Lewiston, Maine, U.S.�d. Sept.  2, 1943, Ellsworth, Maine) U.S. painter. After attending the Cleveland  School of Alt, he settled in New York City but also lived sporadically in  France and Germany. From 1900 he spent most summers in his native  Maine, painting landscapes. He first exhibited them at Alfred Stiegutz�s  �291� gallery in 1909. In 1913 he exhibited with Der Blaue Reiter in Ber�  lin and at the Armory Show. His early style of abstract painting with  strongly outlined forms and brilliant colours evolved into a personal inter�  pretation of Expressionism, most evident in his bold and brooding Maine  landscapes. He produced a dramatic series of pastels and oil paintings of  New Mexico (1918-20) and in 1932 a notable series of the volcano  Popocatepetl in Mexico.</p><p>Hartline, Haldan Keffer (b.

He is noted for his courtly epics, the Arthu�  rian romances Erec (c. 1180-85) and Iwein (c. 1200), both based on works  by Chretien de Troyes. Through Erec, Arthurian legend first entered Ger�  man literature. Der arme Heinrich (�Poor Heinrich�), his finest poem, is  a didactic religious epic.

At Manchester University in the mid  1930s he built a mechanical computer for solving differential equations,  based on the differential analyzer of Vannevar Bush. During World War II  he was involved with the ENIAC project in the U.S. At the University of  Cambridge he introduced the self-consistent field approximation scheme  that is the basis for most atomic calculations and for the prevailing physi�  cal understanding of the wave mechanics of atoms. The Hartree method�  sometimes called the Hartree-Fock method to acknowledge Vladimir  Fock (1898-1974), who generalized Hartree�s scheme�is widely used to  describe electrons in atoms, molecules, and solids.</p><p>Hartwell, Leland H.

Neither a great ruler nor a prepossessing character, Harun ruled  (786-809) at a time when Islamic society reached its zenith in terms of  wealth, learning, and power. He is best remembered, however, as a cen�  tral character in The Thousand and One Nights, where he is portrayed as  the epitome of the learned and just ruler. In his early years he was strongly  influenced by his mother and by his tutor Yahya of the Barmakid line of  viziers. He succeeded his brother after the latter�s untimely death and  ruled over a realm that was torn increasingly by strife, as regional lead�  ers sought autonomy. On his death, his sons al-Ma�mun and al-Amln fell  into open civil war.</p><p>Harvard University Oldest institution of higher learning in the U.S.  and widely considered one of the most prestigious. Founded in 1636 in  Cambridge, Mass., it was named Harvard College for a Puritan minister,  John Harvard (1607-38), who bequeathed to the school his books and  half of his estate. It became a university with the establishment of the  medical school in 1782. Schools of divinity and law were established in  the early 19th century. Charles Eliot, during his long tenure as president  (1869-1909), made Harvard an institution with national influence. Har�  vard has educated seven U.S. presidents, many Supreme Court justices,  cabinet officers, and congressional leaders, dozens of major literary and  intellectual figures, and numerous Nobel laureates. Its undergraduate  school. Harvard College, contains about one-third of the total student  body. Radcliffe College (1879) was a coordinate undergraduate women�s  college. From 1960 women graduated from both Harvard and Radcliffe,  and in 1999 Radcliffe was absorbed by Harvard, the name surviving in  the Radcliffe Institute for Advanced Study. Harvard University also has  graduate or professional schools of business, education, government, den�  tistry, architecture and landscape design, and public health. Among its  affiliated research institutes are the Museum of Comparative Zoology, the  Peabody Museum of Archaeology and Ethnology, and the Fogg Art  Museum. Its Widener Library is one of the largest and most important  libraries in the world.</p><p>harvestman See daddy longlegs</p><p>Harvey, Paul (b.

He became a news commentator</p><p>and analyst for ABC in 1944 and a syndicated columnist in 1954. Noted  for his firm, staccato delivery and his conservative but individualistic  opinions on current events, he enjoyed an almost unparalleled longevity  as a national broadcaster.</p><p>Harvey, William (b. April 1, 1578, Folkestone, Kent, Eng.�d. June  3, 1657, London) English physician. He studied at Cambridge University  and later at the University of Padua, then considered the best medical  school in Europe. After receiving a medical diploma, he was appointed  to St. Bartholemew�s Hospital (1609). He became one of James I�s phy�  sicians c. 1618 and continued as a king�s physician for Charles I, whose  personal friend he became. Harvey�s elucidation of blood circulation over�  turned the work of Galen and advanced that of Andreas Vesalius and Hiero�  nymus Fabricius. To reach his conclusions, Harvey depended on his own  observations and reasoning, numerous animal dissections, autopsies, and  clinical observations. His Anatomical Exercise Concerning the Motion of  the Heart and Blood in Animals (1628) recorded his findings. It clarified  the function of heart valves, proved that blood did not pass through the  septum in the heart, explained the purpose of valves in the veins and of  the pulmonary circulation, showed that blood is pumped from the atria  into the ventricles and then into the rest of the circulatory system, and  proved that the pulse reflected heart contractions.</p><p>Haryana \,har-e-'a-n9\ State (pop., 2001 prelim.: 21,082,989), northern  India. Bordered by the states of Rajasthan, Punjab, Uttaranchal, and Uttar  Pradesh and the Delhi national capital territory, it occupies an area of  17,070 sq mi (44,212 sq km). The city of Chandigarh is the joint admin�  istrative capital of Haryana and Punjab. The region is the legendary birth�  place of Hinduism, and its festivals attract many pilgrims. Most of Haryana  lies on the flat Gangetic Plain, an area that has seen waves of migration  from the time of Alexander the Great. It came under the control of the  British East India Company in 1803, became a part of Punjab in 1858, and  became a separate state in 1966. Its economy is mainly agricultural.</p><p>Harz \'harts \ Mountains Mountain range, central Germany. Lying  between the Weser and Elbe rivers, it is 60 mi (100 km) long and about  20 mi (32 km) wide. The northwestern and highest portion is known as  the Oberharz, and the more extensive southeastern part is the Unterharz;  the Brocken group, dividing the two, is considered part of the Oberharz.  The highest peak is Mount Brocken. The Harz owes its early settlement  and intensive development from the 10th to the 16th century to mining  and metallurgy (silver, lead, iron, copper, and zinc). Its most important  industry is tourism.</p><p>Hasan Vha-san\ in full Hasan ibn �All ibn Abl Talib (b. 624,  Arabia�d. 680, Medina) Grandson of Muhammad, the elder son of  Muhammad�s daughter Fajimah. He is one of the five most revered per�  sons in the ShTite branch of Islam. After the murder of his father, �Au, in  661, he was seen by many as the Prophet�s rightful heir. When Mu'awiyah  I opposed Hasan�s succession and began to prepare for war, Hasan raised  an army to meet him. Plagued by defections, however, he opened peace  negotiations within the year and abandoned the caliphate to his opponent.  For the rest of his life he lived quietly in Medina.</p><p>Hasan al-Basrl Vha-san-al-bas-'re\, al- in full Abu SaTd ibn Abl  al-Hasan Yasar al-Basrl (b. 642, Medina, Arabia�d. 728, Basra,  Iraq) Muslim ascetic and major figure in early Islam. He took part in the  conquest of eastern Iran as a young soldier. He then settled at Basra, and  from 684 he was a popular preacher. He emphasized the practice of reli�  gious self-examination and asserted that true Muslims must live in a state  of anxiety about their destiny after  death. Rejecting determinism, he  held that people are entirely respon�  sible for their actions. Political oppo�  sition forced him into hiding (705-  714), but he afterward lived openly  in Basra.

It was a reaction against rigid  legalism and Talmudic learning in favour of a joyful form of worship that  served as a spiritual outlet for the common people. Hasidism began with  the preaching of the man later known as the Ba'al Shem Tov. Teaching that  God was immanent in all things and that piety was more important than  scholarship, he won followers known as Hasidim (�loyalists�). Dov Baer  founded the first Hasidic community c. 1710, and countless small com�  munities soon sprang up in Poland, Russia, Lithuania, and Palestine, each  led by a zaddik. Communal services were marked by dancing, shouting,  and singing, through which participants reached a state of spiritual ecstasy.  Though excommunicated from Orthodox Judaism in 1772, the Hasidim  continued to flourish. By the 19th century Hasidism had become an ultra�  conservative movement that was accepted by the Orthodox as legitimate.  Huge numbers of Hasidim fell victim to the Holocaust, but their survi�  vors established vital movements in Israel and the U.S. The Lubavitcher  sect, based in Brooklyn, N.Y., numbers about 200,000.</p><p>Haskala or Haskalah \,has-ka-'la\ Intellectual movement in Euro�  pean Judaism in the 18th�19th century, which sought to supplement tradi�  tional Talmudic studies with education in secular subjects, European  languages, and Hebrew. Partly inspired by the Enlightenment, the Haskala  was sometimes called the Jewish Enlightenment. It originated with pros�  perous and socially mobile Jews, who hoped to use reforms to enable the  Jews to escape ghetto life and enter the mainstream of European society  and culture. This meant adding secular subjects to the school curriculum,  adopting the language of the larger society in place of Yiddish, abandoning  traditional garb, and reforming synagogue services. One of its leaders was  Moses Mendelssohn, who began a revival of Hebrew writing. Haskala�s  emphasis on the study of Jewish history and ancient Hebrew as a means of  reviving Jewish national consciousness influenced Zionism, and its call to  modernize religious practices led to the emergence of Reform Judaism.</p><p>Hasmonean V.haz-mo-'ne-onV dynasty Dynasty of ancient Judaea,  descendants of the Maccabee family. The name derives from their ances�  tor Hasmoneus, but the first of the ruling dynasty was Simon Maccabeus,  who became leader of the Maccabean revolt against the Seleucid king c.  143 bc and, in victory, was made high priest, ruler, and ethnarch of Judaea.

From 1898 to 1918 he exhibited together with a group of New York  and Boston painters known as The Ten, who became the foremost pro�  ponents of U.S. Impressionism. Urban life was his favourite subject, but his  landscapes of New England and rural New York also became popular.</p><p>Paintings such as Washington Arch, Spring (1890) are characterized by  clear, luminous atmosphere and brilliant colour.

On his succession to the  throne, he introduced a new constitution providing for a popularly elected  legislature but exercised authoritarian rule from 1965 to 1970, instituting  a new constitution in 1970. He claimed Western Sahara for Morocco; this  led to ongoing hostilities with the Saharawi guerrilla organization PoLlSA-  rio. In 1986 he became the second Arab leader to meet publicly with an  Israeli leader. He condemned the 1990 invasion of Kuwait by Iraq.

His compositions became widely known and were granted copy�  right protection by the emperor in 1591. A Protestant, he eventually left  Catholic Augsburg to take posts in Niimberg, Ulm, and Dresden. He is best  known for his sacred Latin choral music, including masses, psalms, and  motets, but he also composed Italian madrigals, German part-songs (sev�  eral became Protestant hymns), and instrumental music.</p><p>Hassuna \ha-'sii-n3\ Archaeological site, northern Iraq. An ancient  Mesopotamian town located south of Mosul, it was excavated in 1943^44  and was found to represent an advanced village culture that apparently  spread throughout northern Mesopotamia. At Hassuna itself, six layers of  houses were uncovered, each progressively more substantial. Vessels and  pottery dating to c. 5600-5350 bc were discovered. Similar wares found  elsewhere in the Middle East show that even as early as the 6th millen�  nium bc an extensive trade network existed in the region.</p><p>Hastings, Battle of (Oct. 14, 1066) Battle that ended in the defeat of  Harold II of England by William, duke of Normandy, and established the  Normans as rulers of England. On his deathbed Edward the Confessor had  granted the English throne to Harold, earl of Wessex, despite an earlier  promise to make William his heir. William crossed to England from Nor�  mandy with a skilled army of 4,000-7,000 men, landing at Pevensey in  Sussex and moving eastward along the coast to Hastings. Harold met the  Norman invaders with an army of 7,000 men, many of whom were  exhausted from the forced march south to meet William following  Harold�s victory at the battle of Stamford Bridge three weeks earlier. The  English were defeated after a day-long battle in which Harold was killed.  After the battle, the Norman duke moved his army to London and was  crowned William I on December 25.

As  governor of Bengal (1772-74), he  moved the central government to  Calcutta (now Kolkata) under direct  British control and remodeled the  justice system. In 1774 he acquired  the new title of governor-general,  with responsibilities for supervising  other British settlements in India.</p><p>His powers were shared with a coun�  cil of four, several of whom tried to  blame Hastings for the continuing  abuses of power by Englishmen.</p><p>From 1777 to 1783 he sought to  counter the instability created by the  fall of the Mughal Empire and tried  to maintain peaceful relations with neighbouring states but was drawn into</p><p>f</p><p>Warren Hastings, oil painting by Tilly  Kettle; in the National Portrait Gallery,  London.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>846 I hat &#x25BA; Hauptmann</p><p>the Maratha Wars.

In the West, through the Middle Ages, men wore hats  in the form of caps or hoods, and women wore veils, hoods, or head drap�  eries. The silk top hat originated in Florence c. 1760. The derby (bowler)  was introduced in 1850. The cloth cap with visor was for decades the  international standard for workingmen and boys. Women�s hats went  through periods of astonishing ostentation, the last being the years pre�  ceding World War I. Since c. 1960 the wearing of hats by both men and  women has greatly declined in the West. With 15th-century origins, the  broad-brimmed sombrero is still popular in Mexico and parts of Latin  America. The people of East Asia have devised head coverings as simple  as the Chinese coolie hat, a one-piece flattened cone, and as elaborate and  decorative as the Japanese cap-shaped kammuri of black lacquered silk  decorated with an upright streamer and imperial chrysanthemum crest. In  India the Gandhi cap, fez, and turban are in general use. In regions where  the Ottoman Empire ruled (including the Balkans and North Africa), the  traditional headgear of the fez and tarboosh remained popular for men  until the 20th century. Farther east, from Iran to South Asia (as well as in  parts of coastal Arabia), various types of turbans have been worn by men.  In the Arabian interior, the Levant, and parts of Syria and Iraq, the kaf-  fiyeh (sometimes called a ghutrah), a wide cloth held in place by a camel-  hair cord ( c iqdl), remains customary, even for men sporting Western attire.  In Israel the yarmulke is common, particularly among observant Jews.</p><p>Hat Act (1732) British law that restricted colonial manufacture and  export of hats in competition with English hat makers, limiting the num�  ber of apprentices and forbidding the use of blacks in the trade. Part of  the mercantile policy that restricted trade by the colonies and subordi�  nated them economically, it enabled English hatters to dominate markets  formerly supplied by New England and New York manufacturers.</p><p>Hatch Act (1939, amended 1940) Legislation enacted by the U.S. Con�  gress to eliminate corrupt practices in national elections. The bill was  sponsored by Sen. Carl Hatch of New Mexico (1889-1963) in response  to allegations that officials of the Works Progress Administration were  using their positions to win votes for the Democratic Party in the 1936  election. It forbade intimidation or bribery of voters and restricted politi�  cal campaign activities by federal employees. It also limited campaign  contributions by individuals and spending by campaign committees.</p><p>hate crime In law, a crime directed at a person or persons on the basis  of characteristics such as race, religion, ethnicity, or sexual orientation.  The concept emerged in the U.S. in the late 1970s, and since then laws  have been passed in many U.S. states mandating additional penalties for  violent crimes motivated by bias or bigotry against particular groups.  Several other Western countries, including Australia, Britain, and Canada,  have adopted laws designed to curb violent crime against racial and reli�  gious minorities. For example, German law forbids public incitement and  instigation of racial hatred, including the distribution of Nazi propaganda.</p><p>Hatfields and McCoys Two families of the U.S. Appalachian Moun�  tains who engaged in a backwoods feud in the late 19th century. The  families, each with at least 13 children and numerous other relatives, lived  on opposite sides of a border stream, the Hatfields in West Virginia and  the McCoys in Kentucky. The feud may have originated in opposing alle�  giances in the American Civil War. In 1882 the first murder of a Hatfield  was followed by the murder of three McCoys. Retaliatory raids and mur�  ders continued with little interference from local police. In 1888 a posse  of McCoys led by a deputy sheriff captured nine Hatfields in West Vir�  ginia and took them to Kentucky to stand trial for murder. West Virginia  officials charged Kentucky officials with kidnapping. Newspapers nation�  wide carried the story. The U.S. Supreme Court eventually ruled in favour  of Kentucky. The trials resulted in one sentence of death and eight of  imprisonment. Flare-ups gradually abated by the 1920s.</p><p>Hathor \'ha-tor\ or Athyr Va-'thirV In ancient Egyptian religion, the god�  dess of the sky, of women, and of fertility and love. Her principal animal  form was a cow, and she was strongly associated with motherhood. Her  worship was linked at Heliopolis with that of Re, whose wife or daughter</p><p>she was said to be.

While at school in The  Netherlands (1922-32), he became  president of a group of Indonesian  nationalist students studying over�  seas. He was imprisoned in a concentration camp in West New Guinea for  his activities and then exiled to the island of Bandanaira. He collaborated  with the Japanese during World War II. He became prime minister in 1948  and gained support from Western countries that year by suppressing a com�  munist revolt. Hatta helped guide Indonesia to complete independence in  1949. He became vice president under Sukarno in 1950, but resigned in  1956. After Sukarno�s downfall, he served as an adviser to Suharto.</p><p>Hauhau Vhau-.hatA Member of the Pai Marire, a religious-military cult  of the Maori people of New Zealand. The cult was founded in 1864 by  Te Ua Haumene, who claimed to have been visited by the angel Gabriel  and to have sacrificed his child in repentance for the straying of the Maori  people. A mixture of Jewish, Christian, and Maori beliefs, the movement  held that the Maori were a new chosen people and charged them with  driving out the Europeans and recovering the ancestral lands. The effort  failed, though fighting lasted until 1872. Some cult beliefs have persisted  among the Maoris.</p><p>Hauptmann Vhaupt-.manN, Gerhart (Johann Robert) (b.

The Hausa, numbering some 32 million, are the largest ethnic  group in the area. In the mid 14th century a confederation of Hausa states  was formed, influenced by the spread of Islam from the Mali empire. Hausa  society traditionally was, and to some extent continues to be, organized  on a feudal basis. The head of an emirate is surrounded by titled office�  holders who hold villages as fiefs, from which their agents collect taxes.  The economy has traditionally rested on agriculture, though craftwork and  trade are also important. Hausa society is markedly hierarchical; the rank�  ing, both of offices and social classes, is expressed in an elaborate eti�  quette.

It was  founded by the Spanish in 1515 and moved to its present location in 1519.  The de facto capital of Cuba by 1553, it was Spain�s chief naval station  in the New World. Its harbour was the scene of the destruction of the U.S.  battleship Maine in 1898, the immediate cause of the Spanish-American  War. Before 1959, when Fidel Castro came to power, Havana was a haven  for U.S. tourists, offering gambling and showy nightlife. In addition to  being Cuba�s commercial and industrial centre, it contains many build�  ings of Spanish colonial style, including the 17th-century Cathedral of  Havana, the Museum of the City of Havana, and Morro Castle.

Czech play�  wright and dissident, first president of the Czech Republic (from 1993).  He worked in a Prague theatre from 1959 and became resident playwright  by 1968. His plays, including The Memorandum (1965), are absurdist,  satirical examinations of bureaucratic routines that explore the moral com�  promises made by those living under totalitarianism. They were banned  by the communist authorities, and Havel was repeatedly arrested and  imprisoned in the 1970s and �80s. During antigovernment demonstrations  in 1989, he became the leading figure in the Civic Forum, a coalition of  groups pressing for democratic reforms. The Communist Party capitulated  (in the bloodless �Velvet Revolution�) and formed a coalition government  with the Civic Forum, and Havel was elected president in 1989.

Its capital, Honolulu, lies 2,397 mi (3,857  km) west of San Francisco. The state�s major islands are, from west to  east, Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, Maui, and Hawaii;  there are more than 120 islets. The state�s active volcanoes include Mauna  Loa and Kilauea. The majority of the state�s residents live on Oahu. The  original Hawaiians were of Polynesian origin and came from the Mar�  quesas Islands c. ad 400. Capt. James Cook visited the islands in 1778 and  called them the Sandwich Islands. At the beginning of the 19th century,  Kamehameha I united the group under his rule. American whalers began to  stop there; they were followed in 1820 by New England missionaries, and  Western influences changed the islands. While Kamehameha III in 1851  placed Hawaii under U.S. protection, a coup fomented by U.S. sugar  interests resulted in the monarchy�s overthrow and the establishment of  a Republic of Hawaii (1893). In 1898 the new republic and the U.S. agreed  on annexation, and in 1900 Hawaii became a U.S. territory. The bomb�  ing of Pearl Harbor by the Japanese in 1941 led to U.S. involvement in  World War II, and Hawaii became a major naval station. Hawaii became  the 50th state in 1959. Its largest industry is tourism. It is also a world  astronomy centre, with telescopes atop Mauna Kea.</p><p>Hawaii Volcanic island, part of the state of Hawaii, U.S. It lies south  of Maui and constitutes Hawaii county, with Hilo (pop., 2000: 40,759)  the island�s main town.

Their basic unit of land, the ahupuaa, usually extended from  the shore to the mountaintop, providing the occupants with the means to  grow and gather all they needed. Hawaiians had four principal gods and  many lesser deities. Their laws, which included intricate taboos, bore  heavily upon the people, especially women. After the arrival of Christian  missionaries in 1820, some of the more repressive laws and taboos were  abolished, but the native population was devastated by Western diseases.

Hawks usually eat small mam�  mals, reptiles, and insects but  occasionally kill birds. There is often  no difference in plumage between  sexes. Hawks are found on the six  major continents. Most nest in trees,  but some nest on the ground or on  cliffs. True hawks (accipiters) can  usually be distinguished in flight by  their long tails and short, rounded  wings. They are exemplified by the  12-in (30-cm) sharp-shinned hawk  (A. striatus), gray above with fine  rusty barring below, found through�  out much of the New World.

He studied at the University of  Oxford and later received his Ph.D. from Cambridge. He has worked pri�  marily in the field of general relativity and particularly on the physics of  black holes. In 1971 he suggested that numerous objects, formed after the  big bang, each had as much as one billion tons of mass but the size of  only a proton. These �mini black holes� are unique in being subject to  both the laws of relativity, due to their immense mass and gravity, and the  laws of quantum mechanics, due to then - minute size. In 1974 he proposed  that black holes �evaporate� by what is now known as Hawking radiation.  His work greatly spurred efforts to delineate the properties of black holes.  His work also showed the relationship of these properties to the laws of  classical thermodynamics and quantum mechanics. Hawking�s achieve�  ments, despite near-total paralysis from amyotrophic lateral sclerosis,  have earned him extraordinary honours. His books include the best-selling  A Brief History of Time (1988).</p><p>Hawking radiation Radiation theoretically emitted from just outside  the event horizon of a black hole. Stephen W. Hawking proposed in 1974  that subatomic particle pairs (photons, neutrinos, and some massive par�  ticles) arising naturally near the event horizon may result in one particle�s  escaping the vicinity of the black hole while the other particle, of nega�</p><p>tive energy, disappears into it. The flow of particles of negative energy  into the black hole reduces its mass until it disappears completely in a  final burst of radiation.</p><p>Hawkins, Coleman (Randolph) (b.

Hawkins  came to prominence as a member of  Fletcher Henderson�s big band (1924-  34), with which he absorbed the style  of Louis Armstrong and developed the  smooth legato phrasing and robust  tone that set the technical standard  for all tenor players. He worked in  Europe (1934-39) and soon after his  return recorded �Body and Soul,�  which became a commercial success  and one of the masterpieces of impro�  vised jazz. Hawkins was the first  important tenor saxophone soloist in  jazz.

After a successful slave-trading voyage  in 1562-63, a group that included Elizabeth I provided money for a sec�  ond expedition. A Spanish fleet attacked him on his third voyage (1567�  69, with Drake), beginning the quarrel between England and Spain that  led to war in 1585. As treasurer (1577) and controller (1589) of the navy,  he rebuilt older ships and helped design the faster ships that withstood the  Spanish Armada in 1588. He later devised the naval blockade to intercept  Spanish treasure ships.

Intended for the  priesthood, he was recruited at age eight to the choir at St. Stephen�s  Church, Vienna, where he learned violin and keyboard. On leaving the  choir, he began supporting himself by teaching and playing violin, while  undertaking rigorous study of counterpoint and harmony. He came to the  attention of Pietro Metastasio and through him became factotum to the com�  poser Nicola Porpora in exchange for lessons. Gaining entree to high soci�  ety, in 1761 he became head of the musical establishment at the great palace  of the Esterhazy family, which would support him for most of his career. In  this position of artistic isolation but with excellent resources, Haydn felt  free to experiment and was forced to become original. By his late years he  was recognized internationally as the greatest living composer. He com�  posed important works in almost every genre, and his elegant and ingrati�  ating works balance wit and seriousness, custom and innovation. The first  great symphonist, he composed 108 symphonies, including the popular last  12 �London symphonies� (1791-95). He virtually invented the string quar�  tet, and his 68 quartets remain the foundation of the quartet literature. His  choral works include 15 masses and the oratorios The Creation (1798) and  The Seasons (1801). He also wrote 48 piano sonatas and more than 100  beautiful works for the cello-like baryton.

At the 1964 Olympic Games in Tokyo he  won gold medals in the 100-m event and the 4 x 100-m relay; his remark�  able performance in the latter event�his relay split was 8.6 seconds�  helped earn him the unofficial title �World�s Fastest Human.� He later  joined the Dallas Cowboys football team of the NFL as a wide receiver  (1965-76) and kick returner and was a member of the 1972 team that  won the Super Bowl.</p><p>Hayes (Brown), Helen (b. Oct. 10, 1900, Washington, D.C.,  U.S.�d. March 17, 1993, Nyack, N.Y.) U.S. actress. She began her stage  career at age five and made her Broadway debut at nine. She went on to  an illustrious career, starring in Broadway productions such as Caesar and  Cleopatra (1925), What Every Woman Knows (1926), and The Animal  Kingdom (1932) and became known as �the First Lady of the American  Theatre.� Her small physical size belied a majestic stage presence that  made her memorable in Mary of Scotland (1933�34) and Victoria Regina  (1935-39). She starred in revivals of The Skin of Our Teeth (1955), The  Glass Menagerie (1956), and Long Day�s Journey into Night (1971),  acted in numerous radio and television plays, and won Academy Awards  for her films The Sin ofMadelon Claudet{ 1931) and Airport (1970), three  Tony Awards, and the Presidential Medal of Freedom. She was married  to Charles MacArthur.</p><p>Hayes, Rutherford B(irchard) (b. Oct. 4, 1822, Delaware, Ohio,  U.S.�d.

He practiced law in Cincinnati,</p><p>Ohio, where he represented defen�  dants in several fugitive-slave cases  and became associated with the new  Republican Party. After fighting in  the Union army in the American Civil  War, he served in the U.S. House of  Representatives (1865-67). As gov�  ernor of Ohio (1868-72, 1875-76),  he advocated a sound currency  backed by gold. In 1876 he won the  Republican nomination for presi�  dent. His opponent, Samuel Tilden,  won a larger popular vote, but the  Hayes campaign contested the  electoral-vote returns in four states,  and a special Electoral Commission  awarded the election to Hayes. As  part of a secret compromise reached  with Southerners during the electoral  dispute (see Wormley Conference),</p><p>Hayes withdrew the remaining federal troops from the South, ending  Reconstruction, and promised not to interfere with elections there, ensur�  ing the return of white supremacy. His decision to introduce civil-service  reform based on merit provoked a dispute with Roscoe Conkling and the  conservative �stalwart� Republicans. At the request of state governors,  Hayes used federal troops against railroad strikers in 1877. Declining to  run for a second term, he retired to work for humanitarian causes.</p><p>Haymarket Riot (May 4, 1886) Violent confrontation between police  and labour protesters in Chicago that dramatized the labour movement�s  struggle for recognition. Radical unionists had called a mass meeting in  Haymarket Square to protest police brutality in a strike action. A bomb  was thrown into the crowd, killing seven policemen and injuring 60 oth�  ers. Police and workers fired on each other. Public demand for action led  to the arrest of eight anarchists (see anarchism). Convicted of conspiracy  to murder, they were sentenced to death; four were executed and one  committed suicide. In 1893 the three survivors were pardoned by Illinois  Gov. John Peter Altgeld.</p><p>Hayne, Robert Young (b. Nov. 10, 1791, Colleton District, S.C.,  U.S.�d. Sept. 24, 1839, Asheville, N.C.) U.S. politician. In 1823 he  entered the U.S. Senate, where he became a spokesman for the South and  the doctrine of states' rights. In his famous 1830 debate with Daniel Web�  ster on the Constitution, he argued that the federal Constitution was a  compact among the states and that any state might nullify a federal law  that it considered in violation of the constitutional compact (see nullifica�  tion). At the South Carolina nullification convention in 1832, he devel�  oped an ordinance that declared federal tariff laws null and void in the  state. Resigning from the Senate in 1832, he served as governor of South  Carolina (1832-34) and as mayor of Charleston (1834-37).</p><p>Hays Off ice formally Motion Picture Producers and Distribu�  tors of America U.S. organization that promulgated a moral code for  films. In 1922, after a number of scandals involving Hollywood person�  alities, film industry leaders formed the organization to counteract the  threat of government censorship and to create favourable publicity for the  industry. Under Will H. Hays (1879-1954), a politically active lawyer, it  initiated a blacklist, inserted morals clauses into actors� contracts, and in  1930 developed a Production Code that detailed what was morally accept�  able on the screen. The code was supplanted in 1966 by a voluntary rat�  ing system.</p><p>Haywood, William D(udley) (b. Feb. 4,1869, Salt Lake City, Utah,  U.S.�d. May 18,1928, Moscow, Russia) U.S. labour leader. A miner from  the age of 15, he chaired the founding convention of the Industrial Workers  of the World in 1905 and led its organizing efforts. In 1907 he was acquitted  of a charge of involvement in the murder of Idaho�s antilabour former gov�  ernor, Frank Steunenberg (1861-1905). �Big Bill� Haywood then under�  took a speaking tour for the Socialist Party and supported numerous strikes.  He was later forced out of the party for advocating violence. In 1917 he was  convicted of sedition for his opposition to World War I and sentenced to 20  years in prison; in 1921, while free on bail, he fled to Russia.</p><p>Hayworth, Rita orig.

She danced with her father in nightclubs from age 12 and played  bit parts in films from 1935. She cultivated a sophisticated glamour in  Only Angels Have Wings (1939), Strawberry Blonde (1941), and Blood  and Sand (1941). The musicals You�ll Never Get Rich (1941), You Were  Never Lovelier (1942), and Cover Girl (1944) made her a star and a  favourite pinup of U.S. GIs during World War II. Her worldly, erotic role  in Gilda (1946) confirmed her status in Hollywood as �the Love God�  dess.� Her later films include The Lady from Shanghai (1948), Pal Joey  (1957), and Separate Tables (1958).</p><p>hazel See filbert</p><p>Hazeltine Vha-zol-.tinV (Louis) Alan (b.

In the early 1920s he invented the neutrodyne circuit, which  made commercial radio possible by neutralizing the noise that plagued all  radio receivers of the time; by 1927 some 10 million radio receivers were  using the device. Hazeltine later advised the U.S. government on regu�  lation of radio broadcasting, and during World War II he served on the  National Defense Research Committee.</p><p>Hazlitt, William (b. April 10, 1778, Maidstone, Kent, Eng.�d. Sept.  18, 1830, Soho, London) British essayist. He studied for the ministry, but  to remedy his poverty he became instead a prolific critic, essayist, and  lecturer. He began contributing to journals, notably to The Examiner , and  to essay collections, such as The Round Table (1817). His lecture courses  were published as On the English Poets (1818) and On the English Comic  Writers (1819). Many of his most brilliant essays appeared in his two  best-known books, Table Talk (1821) and The Plain Speaker (1826). The  Spirit of the Age (1825) contains some of his most effective writing.</p><p>H.D. See Hilda Doolittle</p><p>Head, Bessie orig. Bessie Amelia Emery (b. July 6, 1937, Pieter�  maritzburg, S.Af.�d.

Episodic tension head�  aches are the most common, usually causing mild to moderate pain on  both sides. They result from sustained contraction of face and neck  muscles, often due to fatigue, stress, or frustration. Headaches are treated  with aspirin, acetaminophen, or other NSAIDs. Chronic daily headaches are  similar but more frequent. They usually have a psychological cause and  respond to certain antidepressants. They may also come from overuse of  pain relievers. Migraine and cluster headaches are vascular headaches.  Headaches may also be caused by distension of arteries at the base of the  brain, from fever, hangover, or an attack of high blood pressure. Head�  ache can be a symptom of meningitis, hemorrhagic stroke, or tumour.</p><p>Heade Yhed\, Martin Johnson (b. Aug. 11, 1819, Lumberville, Pa.,  U.S.�d. Sept. 4, 1904, St. Augustine, Fla.) U.S. painter. He studied in  Europe and Britain, then returned to the U.S. to take up portrait and land�  scape painting. An avid naturalist, he made extensive trips in South and  Central America and the Caribbean (1863-70), where he produced lumi�  nous, meticulously detailed images of the tropical forests and landscapes.  The New England coast and the rocky shore of Lake George, N.Y., also  inspired notable paintings. He was a leading exponent of luminism.</p><p>headhunting Practice of removing, displaying, and in some cases pre�  serving human heads.

Headhunting is thus sometimes  found with certain forms of cannibalism as well as with human sacrifice. It  has been practiced worldwide and may date to Paleolithic times. The  region of Assam in northeastern India was home to many headhunting  peoples. In South America, the skull was removed and the skin was  packed with hot sand to create a shrunken head.</p><p>health Extent of continuing physical, emotional, mental, and social abil�  ity to cope with one�s environment. Good health is harder to define than  bad health (which can be equated with presence of disease) because it  must convey a more positive concept than mere absence of disease, and  there is a variable area between health and disease. A person may be in  good physical condition but have a cold or be mentally ill. Someone may  appear healthy but have a serious condition (e.g., cancer) that is detect�  able only by physical examination or diagnostic tests or not even by these.</p><p>health insurance System for the advance financing of medical  expenses through contributions or taxes paid into a common fund to pay  for all or part of health services specified in an insurance policy or law.  The key elements are advance payment of premiums or taxes, pooling of  funds, and eligibility for benefits on the basis of contributions or employ�  ment without an income or assets test. Health insurance may apply to a  limited or comprehensive range of medical services and may provide for  full or partial payment of the costs of specific services. Benefits may con�  sist of the right to certain medical services or reimbursement of the insured  for specified medical costs. Private health insurance is organized and  administered by an insurance company or other private agency; public  health insurance is run by the government (see social insurance). Both  forms of health insurance are to be distinguished from socialized medi�  cine and government medical-care programs, in which doctors are  employed directly or indirectly by the goverment, which also owns the  health-care facilities (e.g., Britain�s National Health Service). See also</p><p>INSURANCE.</p><p>health maintenance organization (HMO) Public or private  organization providing comprehensive medical care to subscribers on the  basis of a prepaid contract. HMOs deliver a broad range of health ser�  vices for a fixed fee. In the prepaid group-practice model, physicians are  organized into a group practice with one insuring agency. A medical care  foundation, or individual practice association, usually involves multiple  insurance companies and reimburses members of a loose network of indi�  vidual physicians from subscribers� prepaid fees. Originally viewed as a  way to control health-care costs and meet increased demand for health  services, HMOs have become controversial because some limit care by  refusing to pay for tests or treatment against their own doctors� advice.</p><p>Healy, T(imothy) M(ichael) (b. May 17, 1855, Bantry, County Cork,  Ire.�d. March 26, 1931, Dublin) Irish political leader. Soon after he  entered Parliament in 1880, the �Healy Clause� of the Land Act of 1881,  protecting tenant farmers� agrarian improvements from rent increases,  made him popular in Ireland. Long associated with Charles Stewart Parnell,  he broke with him in 1886. He grew dissatisfied with both the Liberals and  the Irish Nationalists in the wake of the 1916 Easter Rising, and after 1917  he supported Sinn Fein. He was supported by both the British and Irish min�  istries as governor-general (1922-28) of the new Irish Free State.</p><p>Heaney \'he-ne\, Seamus (Justin) (b. April 13, 1939, near Cas-  tledawson. County Londonderry, N.Ire.) Irish poet. After studying at  Queen�s University in Belfast, he became a teacher and lecturer. Appalled  by the violence in his native Northern Ireland, he moved to the Republic  of Ireland in 1972. In recent years he has taught at Harvard, Oxford, and  Cambridge. His works, rooted in Northern Irish rural life, evoke histori�  cal events and draw on Irish myth, but they also reflect the land�s recent  troubled decades. His collections include Death of a Naturalist (1966),  Door into the Dark (1969), North (1975), Station Island (1984), The Haw  Lantern (1987), Seeing Things (1991), and The Spirit Level (1996). Pre�  occupations (1980) consists of essays on poetry and poets. He also made  a noteworthy translation of Beowulf. He received the Nobel Prize for Lit�  erature in 1995.</p><p>hearing In law, a trial, or more specifically the formal examination of  a cause before a judge according to the laws of the land. In popular usage  the term often refers to a formal proceeding before a magistrate prior to  the inception of a case, and in particular to a preliminary hearing, where  a magistrate or judge determines whether the evidence justifies proceed�  ing with the case.</p><p>hearing or audition or sound reception Physiological process of  perceiving sound. Hearing entails the transformation of sound vibrations  into nerve impulses, which travel to the brain and are interpreted as  sounds. Members of two animal groups, arthropods and vertebrates, are  capable of sound reception. Hearing enables an animal to sense danger,  locate food, find mates, and, in more complex creatures, engage in com�  munication (see animal communication). All vertebrates have two ears,  often with an inner chamber housing auditory hair cells (papillae) and an  outer eardrum that receives and transmits sound vibrations. Localization  of sound depends on the recognition of minute differences in intensity  and in the time of arrival of the sound at the two ears. Sound reception  in mammals is generally well developed and often highly specialized, as  in bats and dolphins, which use echolocation, and whales and elephants,  which can hear mating calls from tens or even hundreds of miles away.  Dogs and other canines can similarly detect faraway sounds. The human  ear can detect frequencies of 20-20,000 hertz (Hz); it is most sensitive  to those between 1,000 and 3,000 Hz. Impulses travel along the central  auditory pathway from the cochlear nerve to the medulla to the cerebral  cortex. Hearing may be impaired by disease, injury, or old age; some dis�  orders, including deafness, may be congenital. See also hearing aid.</p><p>hearing aid Device that increases the loudness of sounds in the user�s  EAR. Its principal components are a microphone, an amplifier, and an ear�  phone. Hearing aids are increasingly smaller and less conspicuous, fitting  behind the earlobe or within the ear canal. They have widely differing  characteristics, amplifying different components of speech sounds for  maximum comprehension by each wearer. Hearing aids with automatic  volume control vary the amplification automatically with the input.</p><p>Hearn, (Patricio) Lafcadio (Tessima Carlos) Japanese Koi�  zumi Yalcumo (b. June 27, 1850, Levkas, Ionian Islands, Greece�d.  Sept. 26, 1904, Okubo, Japan) Irish-U.S.-Japanese writer, translator, and  teacher. He immigrated to the U.S. at age 19 and worked as a reporter and  translator, writing on a wide range of subjects. In 1890 he traveled as a  magazine writer to Japan, where he soon became a teacher, took a Japa�  nese wife and name, and became a Japanese subject. Articles and books  about Japan�s customs, religion, and literature followed, including  Glimpses of Unfamiliar Japan (1894), Exotics and Retrospective (1898),  In Ghostly Japan (1899), Shadowings (1900), and A Japanese Miscellany  (1901); Kwaidan (1904) is a collection of supernatural stories and haiku  translations.

April 29, 1863, San Fran�  cisco, Calif., U.S.�d. Aug. 14,</p><p>1951, Beverly Hills, Calif.) U.S.  newspaper publisher. Hearst in 1887  took over the struggling San Fran�  cisco Examiner, which he remade  into a successful blend of investiga�  tive reporting and lurid sensational�  ism. After buying the New York  Morning Journal (later New York  Journal-American) in 1895, he  fought fierce circulation wars with  other papers and helped bring about  the era of yellow journalism, employ�  ing circulation-boosting strategems  that profoundly influenced U.S. jour�  nalism. Distorted reportage in Hearst  papers fanned public sentiment  against Spain that led to the Spanish-  American War. He served in Con�  gress (1903-07) but ran  unsuccessfully for other offices. In  the 1920s he built a grandiose castle in San Simeon, Calif. At the peak of  his fortune in 1935 he owned 28 major newspapers, 18 magazines, radio  stations, movie companies, and news services. Extravagance and the  Depression weakened him financially, and by 1940 he had lost control of  his empire. He spent his last years in virtual seclusion.</p><p>heart Organ that pumps blood, circulating it to all parts of the body (see  circulation). The human heart is a four-chambered double pump with its  right and left sides fully separated by a septum and subdivided on both  sides into an atrium above and a ventricle below. The right atrium receives  venous blood from the superior and inferior venae cavae (see vena cava)</p><p>William Randolph Hearst, 1906.</p><p>LIBRARY OF CONGRESS, WASHINGTON, D.C.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>852 I heart attack &#x25BA; heat pump</p><p>and propels it into the pulmonary circulation.

Oxygen-rich blood from the lungs enters the heart  through the pulmonary veins, passing into the left atrium and on to the left ventricle.  Contraction of the muscles of the left ventricle forces blood into the aorta. The mitral  valve prevents blood from moving back into the left atrium during contraction. Vari�  ous arteries branch off from the aorta to supply blood to all parts of the body.  Oxygen-poor blood draining from the body into the superior vena cava and infe�  rior vena cava flows to the right atrium, through the tricuspid valve, and into the  right ventricle.

Hypertension, diabetes mellitus, high  cholesterol, cigarette smoking, and coronary heart disease increase the risk.  Symptoms include severe chest pain, often radiating to the left arm, and  shortness of breath. Up to 20% of victims die before reaching the hos�  pital. Diagnosis is done by electrocardiography and by analysis for enzymes  in the blood. Treatment aims to limit the area of tissue death (infarct) and  prevent and treat complications. Thrombolytic (clot-dissolving) drugs  may be administered. Beta-blockers alleviate pain and slow the heart rate.  Angioplasty or coronary bypass restores blood flow to heart muscle.  Follow-up may include drugs, exercise programs, and counseling on diet  and lifestyle changes.</p><p>heart clam See cockle</p><p>heart disease Any disorder of the heart. Examples include coronary  HEART DISEASE, CONGENITAL HEART DISEASE, and PULMONARY HEART DISEASE, as well  as rheumatic heart disease (see rheumatic fever), hypertension, inflamma�  tion of the heart muscle (myocarditis) or of its inner or outer membrane  (endocarditis, pericarditis), and heart valve disease. Abnormalities of the  heart�s natural pacemaker or of the nerves that conduct its impulses cause  arrhythmias. Some connective tissue diseases (notably systemic lupus erythe�  matosus, rheumatoid arthritis, and scleroderma) can affect the heart. Heart  failure may result from many of these disorders.</p><p>heart failure Inability of one or both sides of the heart to pump enough  blood for the body. Causes include pulmonary heart disease, hypertension,  and coronary atherosclerosis. A person with left-sided heart failure expe�  riences shortness of breath after exertion, difficulty in breathing while</p><p>lying down and night breathlessness, and abnormally high pressure in the  pulmonary veins. A person with right-sided failure experiences abnor�  mally high pressure in the systemic veins, liver enlargement, and accu�  mulation of fluid in the legs. A person with failure of both ventricles has  an enlarged heart and a three-beat heartbeat. Treatment includes bed rest,  medications such as digitalis, control of excess salt and water retention,  and elimination of the underlying cause. See also congestive heart failure.</p><p>heart transplant Procedure to remove a diseased heart and replace it  with a healthy one from a legally dead donor. The first was performed in  1967 by Christiaan Barnard. The diseased heart is removed (except for  some atrial tissue to preserve nerve connections to the natural pacemaker).  The new heart is put in place and connected to the recipient�s blood ves�  sels. Patients and donors are matched for tissue type, but the patient�s  immune system must still be suppressed to prevent rejection (see immuno�  suppression). A successful transplant can enable the recipient to have an  active life for many years.</p><p>heartwood Dead, central wood of trees. Its cells usually contain tan�  nins or other substances that make it dark and sometimes fragrant. Heart-  wood is mechanically strong, resistant to decay, and less easily penetrated  by wood-preservative chemicals than other types of wood. One or more  layers of living and functional sapwood cells are periodically converted  to heartwood.</p><p>heartworm Species (Dirofilaria immitis) of filarial worm that parasit�  izes mammals, especially dogs. Up to 500 adult heartworms, which can  grow to 6-12 in. (15-30 cm) long, live in the dog�s heart, and the microfi�  lariae (embryonic larvae) pass into the blood. Mosquitoes transfer infested  blood from dog to dog. Both adult and larval heartworms tax the heart  and restrict blood flow to the lungs, kidneys, and liver. By the time vis�  ible symptoms (chronic cough, labored breathing, listlessness, heart fail�  ure) develop, it may be too late for treatment. Preventive medicines and  treatments, including surgery, exist.</p><p>heat Energy transferred from one body to another as the result of a dif�  ference in temperature. Heat flows from a hotter body to a colder body  when the two bodies are brought together. This transfer of energy usually  results in an increase in the temperature of the colder body and a decrease  in that of the hotter body. A substance may absorb heat without an increase  in temperature as it changes from one phase to another�that is, when it  melts or boils. The distinction between heat (a form of energy) and tem�  perature (a measure of the amount of energy) was clarified in the 19th  century by such scientists as J.-B. Fourier, Gustav Kirchhoff, and Ludwig  Boltzmann.</p><p>heat capacity Ratio of heat absorbed by a material to the change in  temperature. It is usually expressed as calories per degree in terms of the  amount of the material being considered. Heat capacity and its tempera�  ture variation depend on differences in energy levels for atoms. Heat  capacities are measured with a calorimeter and are important as a means  of determining the entropies of materials. See also specific heat.</p><p>heat exchanger Any of several devices that transfer heat from a hot  to a cold fluid. In many engineering applications, one fluid needs to be  heated and another cooled, a requirement economically accomplished by  a heat exchanger. In double-pipe exchangers, one fluid flows inside the  inner pipe, and the other in the annular space between the two pipes. In  shell-and-tube exchangers, many tubes are mounted inside a shell; one  fluid flows in the tubes and the other flows in the shell, outside the tubes.  Special-purpose devices such as boilers, evaporators, superheaters, con�  densers, and coolers are all heat exchangers. Heat exchangers are used  extensively in fossil-fuel and nuclear power plants, gas turbines, heating  and air conditioning, refrigeration, and the chemical industry. See also  COOLING SYSTEM.</p><p>heat exhaustion or heat prostration Response of the body to  excessive heat. The body temperature rises moderately and heavy perspi�  ration persists. Heat exhaustion results from inadequate water and salt  intake and can lead to dehydration and collapse. It may progress to heat�  stroke if not treated by lying down in a cool place and drinking fluids,  preferably water with salt added.</p><p>heat pump Device for transferring heat from a substance or space at  one temperature to another at a higher temperature. It consists of a com�  pressor, a condenser, a throttle or expansion valve, an evaporator, and a  working fluid (refrigerant). The compressor delivers vapourized refriger�  ant to the condenser in the space to be heated. There, cooler air condenses</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>heat-treating &#x25BA; heavy spar I 853</p><p>the refrigerant and becomes heated during the process. The liquid refrig�  erant then enters the throttle valve and expands, coming out as a liquid-  vapour mixture at a lower temperature and pressure. It then enters the  evaporator, where the liquid is evaporated by contact with the warmer  space. The vapour then passes to the compressor and the cycle is repeated.  A heat pump is a reversible system and is commonly used both to heat  and to cool buildings. It operates on the same thermodynamic principles  as REFRIGERATION.</p><p>heat-treating Changing the properties of materials such as metals or  glass by processes involving heating. It is used to harden, soften, or  modify other properties of materials that have different crystal structures  at low and high temperatures. The type of transformation depends on the  temperature that the material is heated to, how fast it is heated, how long  it is kept heated, what temperature it is first cooled to, and how fast it is  cooled. For example, quenching hardens steel by heating it to high tem�  peratures and then quickly immersing it in room temperature oil, water,  or salt brine to �freeze� the new crystal structure; in cryogenic treatments  the cooling bath ranges from -180 to -70 �C (-300 to -100 �F), and it is  often used in treating high-carbon and high-alloy steels. The two main  approaches to softening a metal (to restore its ductility) are annealing, in  which its temperature is slowly raised, held for some time, and slowly  cooled, and tempering, in which it is slowly heated in an oil bath and held  for some hours.</p><p>Heath, Sir Edward (Richard George) (b. July 9, 1916, Broad-  stairs, Kent, Eng.�d. July 17, 2005, Salisbury, Wiltshire) British politi�  cian, prime minister of Britain (1970-74). He held various government  positions after being elected to Parliament in 1950, and after the Conser�  vative defeat in 1964 he became a major opposition figure. As prime min�  ister, he faced the crisis of violent conflict in Northern Ireland, over which  he imposed direct British rule in 1972, and won French acceptance of  British entry into the European Economic Community. Unable to cope with  Britain�s mounting economic problems, chiefly rising inflation and unem�  ployment and crippling labour strikes, he was succeeded as prime min�  ister by Harold Wilson in 1974 and replaced as party leader by Margaret  Thatcher in 1975. Heath, who was knighted in 1992, remained in the  House of Commons until 2001.</p><p>heath family Family Ericaceae, made up mostly of shrubs and small  trees, including azaleas, rhododendrons, mountain laurel, blueberries, and  the low evergreen shrubs of the genus Erica (see erica). A large percent�  age of the family�s approximately 110 genera and 4,000 species are cul�  tivated. Members are widely distributed, extending into the subarctic and  along mountain chains through the tropics. They are often evergreen spe�  cies that thrive on open, barren land with usually acid and poorly drained  soils. See also heather.</p><p>Heathcoat, John (b. Aug. 7, 1783, Duffield, Derbyshire, Eng.�d. Jan.  18, 1861, Tiverton, Devon) British inventor. The lacemaking machine he  patented in 1809, the most complex textile machine then in existence,  produced an exact imitation of handmade pillow lace. His lace factory  was destroyed by Luddites in 1816. He later developed means for orna�  menting net in the course of manufacture, for making ribbons as well as  plaited and twisted net, and for winding raw silk from cocoons.</p><p>heather or Scotch heather Low evergreen shrub (Calluna vulgaris )  of the heath family, widespread in western Europe and Asia, North  America, and Greenland. It is the chief vegetation on many wastelands  of northern and western Europe. C. vulgaris is distinguished from true  heaths, which are sometimes loosely called heather, by the lobes of its  calyx (see flower), which conceal the petals; in true heaths the petals cover  the calyx. Scotch heather has purple stems, close-leaved green shoots, and  feathery spikes of bell-shaped flowers. It has various economic uses: large  stems are made into brooms, shorter ones are tied into bundles that serve  as brushes, and long trailing shoots are woven into baskets.</p><p>heating Process of raising the temperature of an enclosed space. Heat  can be delivered by convection, radiation, and thermal conduction. With  the exception of the ancient Romans, who developed a form of central  heating, most cultures relied on direct heating methods such as fireplaces  and stoves. Central heating, adopted for use again in the 19th century, is  a method of indirect heating: heat is produced away from the occupants  and then conveyed to them. In warm-air heating, air heated by a furnace  rises through ducts to rooms above, where it is emitted through grills. In  hot-water systems, a pump circulates water from a boiler through a sys�  tem of pipes to radiators or convectors in rooms. In steam systems, steam</p><p>is generated in the boiler and led to radiators through pipes. The high  temperature of the steam makes it hard to control, and steam heating has  been largely superseded. A common type of electric heating system con�  verts electric current to heat by means of resistors that emit radiant energy.  See also radiant heating, solar heating.</p><p>heatstroke Debility caused by exposure to heat and humidity, usually  for many hours, called sunstroke when caused by direct sunlight. Body  temperature is 106-110�F (41^J3�C) or higher. Perspiration almost stops,  leading to the rapid temperature rise, collapse, and coma. Cooling with  ice-water baths or packs, with massage to promote circulation, is urgent  to save the victim�s life. Even after body temperature drops, circulatory  disorder and brain damage may cause death. See also heat exhaustion.</p><p>heaven Dwelling place of God or the gods and the abode of the blessed  dead. The term also refers to the  celestial sphere, the place of the sun,  moon, planets, and stars and the  source of light, which symbolizes  good. For later Judaism and Chris�  tianity, heaven is the destination of  the faithful after a general resurrec�  tion of the dead, in contrast to hell,  the place of punishment for the  wicked. Islam has a similar belief. In  Chinese religion, heaven is equated  with the divine will, which guides  the operation of all physical and  moral laws. In some Mahay ana Bud�  dhist sects, heaven is a paradise for  those who have received the saving  grace of Amitabha.</p><p>Heaven's Gate U.S. religious  group that committed mass suicide  in 1997 and that had been founded  on a belief in unidentified flying  objects. Established by Marshall H.</p><p>Applewhite (1932-1997) and Bon�  nie Nettles (1927-1985) in 1972, the  group assumed a variety of names  over the years, including Human Individual Metamorphosis. As prepara�  tion for the �transition� to a new life on a spaceship, it advocated self-  renunciation to the point of castration. Settling finally in the San Diego  area in 1996, the group support itself by creating sites on the World Wide  Web and quietly preparing for the end time. They believed that the comet  Hale-Bopp was followed by a spaceship that would take them to a better  place. On March 26, 1997, as the comet approached, the remaining 39  members of the group took poison and committed suicide in a carefully  orchestrated manner.</p><p>Heaviside Vhe-ve-,sld\, Oliver (b. May 18, 1850, London, Eng.�d.  Feb. 3, 1925, Torquay, Devon) English physicist. In 1902 he predicted the  presence of the ionosphere. Since Arthur Kennelly (1861-1939) had made  a similar prediction, the ionosphere was long known as the Kennelly-  Heaviside layer. Heaviside�s work on telephone theory made long�  distance service practical. In his Electromagnetic Theory (1893-1912) he  postulated that an electric charge would increase in mass as its velocity  increased, anticipating one aspect of Albert Einstein�s special theory of  relativity. He also developed the system of mathematical transforms  known as Heaviside calculus.</p><p>heavy hydrogen See deuterium</p><p>heavy metal Type of rock music marked by highly amplified, distorted  �power chords� on electric guitar, a hard beat, thumping bass, and often  dark lyrics. It evolved in Britain and the U.S. in the late 1960s from the  heavy, blues-oriented music of Steppenwolf, Jimi Hendrix, and others. In  the 1970s the genre was defined by the music of bands such as Led Zep�  pelin, Black Sabbath, Kiss, AC/DC, and Aerosmith. After a period of  decline, a new generation of bands such as Def Leppard, Iron Maiden,  Motley Criie, and Van Halen revived heavy metal in the 1980s, along with  the careers of many of its pioneers, including Ozzy Osbourne of Black  Sabbath.</p><p>heavy spar See barite</p><p>"The Angel Shows John the Heavenly  Jerusalem/' from the Apocalypse of St.  John, c. 1020; in the Staatsbibliothek  Bamberg, Germany (MS. 140).</p><p>COURTESY OF THE STAATSBIBLIOTHEK BAMBERG,  GERMANY</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>854 I heavy water &#x25BA; Hebrides</p><p>heavy water or deuterium \du-'tir-e-3m\ oxide Water composed  of two atoms of deuterium (D; a heavy isotope of hydrogen) and one atom  of oxygen (O), chemical formula D 2 0.

The event was probably a ritual reenactment of the unification  of Egypt by Menes c. 3000 bc. After beginning the celebration by offer�  ing a sacrifice to the gods, the king was crowned with the white crown  of Upper Egypt, followed by the red crown of Lower Egypt. He then ran  a ritual course four times, before being carried in procession to the chap�  els of Horus and Seth.</p><p>Hebbel, (Christian) Friedrich (b.

After an early life marked by poverty, he became famous with  the prose play Judith (1840), based on the biblical story. Among his later  tragedies, Maria Magdalene (1843), portraying the lower middle class,  and Gyges and His Ring (1856), probably his most mature and subtle  work, are realistic psychological tragedies that make use of G.W.F.  Hegel�s concepts of history and moral values. The mythological trilogy  Die Nibelungen (1862) grandiosely depicts the clash between heathen and  Christian.</p><p>Hebe Vhe-be\ Greek goddess of youth, daughter of Zeus and Hera.

After the mid 1950s, however, she moved to Paris, where she produced a  number of novels that are psychological examinations of violence, rebel�  lion, and the quest for personal freedom. She was three times the recipi�  ent of Canada�s highest literary award, the Governor General�s Award,  once for her poetry in Poems (1960) and twice for her fiction ( Kamour-  ska, 1970, and Burden of Dreams, 1992).</p><p>Hebert \a-'ber\, Jacques (-Rene) known as Pere Duchesne</p><p>Vper-diE-'shenX (b.

He wrote political satires under his pen name,  and his newspaper, Le Pere Duchesne, was widely read. He became influ�  ential in the Cordeliers Club and with his followers, called Hebertists,  helped overthrow the monarchy in 1792. He strongly supported the con�  version of the Cathedral of Notre-Dame and 2,000 other churches to the  worship of Reason. As spokesman for the sansculottes, he pressured the  Jacobin regime to institute the Reign of Terror. By 1794 he was regarded  as a dangerous extremist, and the Committee of Public Safety had him  arrested and guillotined.</p><p>Hebraic law Law codes of ancient Israel found in the Jewish Scrip�  ture (Old Testament). Three separate codes are usually distinguished: the  Book of the Covenant, the Deuteronomic Code, and the Priestly Code.  The Book of the Covenant is found in Exodus 20-23 and is similar to the  much earlier Code of Hammurabi in Babylon. The Deuteronomic Code in  Deuteronomy 12-26 is a revision of earlier Israelite laws and was used  in the effort to purify the worship of Yahweh (God) from Canaanite and  other influences (see Deuteronomic Reform). The Priestly Code, found in  parts of Exodus, all of Leviticus, and much of Numbers, covers mostly  ceremonial practices.</p><p>Hebrew alphabet Script used to write the Hebrew language and a  number of other languages used as vernaculars by Jews, including Ladino  and Yiddish. The modern 22-letter alphabet in use today differs only slightly  from the script adapted by Jewish scribes in the early centuries bc from  the square script used to write Imperial Aramaic. Prior to this adaptation,  Hebrew was written in a linear script borrowed ultimately from the Phoe�  nicians and first attested in the 9th century bc; though the linear script  passed out of favour among Jews, Samaritans, adherents of an ancient  offshoot of Judaism, continued to use it into modern times. Hebrew is  written from right to left, and the letter shapes�at least originally�  represented only consonants. Later certain of the consonants were utilized  to denote vowels in certain positions, and by c. ad 600 a system of dia�  critics, or �points,� were used to show all vowels in the text of the Bible.</p><p>Hebrew calendar See Jewish calendar</p><p>Hebrew language Semitic language that is both a sacred language of  Judaism and a modern vernacular in Israel. Like Aramaic, to which it is  closely related, Hebrew has a documented history of nearly 3,000 years.  The earliest fully attested stage of the language is Biblical Hebrew: the  earlier parts (�Standard Biblical Hebrew�) date before 500 bc and include  even older poetic passages; the later parts (�Late Biblical Hebrew�) were  composed c. 500-200 bc. Post-Biblical Hebrew, variously termed Rab�  binic or Mishnaic Hebrew (see Mishna), is characterized by an early  period when Hebrew was still probably to some degree a vernacular and  a later period, after c. ad 200, when Aramaic became the everyday speech  of Jews in the Middle East. The 6th and 7th centuries marked a transi�  tion to Medieval Hebrew. The resurrection of Hebrew as a vernacular is  closely linked with the 18th-century Haskala movement and 20th-century  Zionism. Contemporary Israeli Hebrew is spoken by about five million  people in Israel and abroad.

They are sepa�  rated into two groups, the Outer Hebrides and the Inner Hebrides, divided  by the Little Minch Strait. The Outer Hebrides are administered as the  Eilean Siar (Western Isles) council area (pop., 2001: 26,502). The north�  ern Inner Hebrides lie within the Highland council area, and the southern  Inner Hebrides are part of Argyll and Bute council area. Composed of  more than 40 islands, only a few of which are inhabited, the Hebrides  were originally settled by Celts. Norse raids, which led to Norse rule,  began after the 8th century and lasted until 1266, when the islands were  ceded to Scotland. Their economy centres on farming, fishing, and weav�  ing, the latter noted especially for Harris tweed.</p><p>Hebe carrying nectar and ambrosia,  detail of a vase painting; in the Jatta  Museum, Ruvo di Puglia, Italy</p><p>AUNARI�GIRAUDON FROM ART RESOURCE</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Hebron &#x25BA; Hegel I 855</p><p>Hebron Vhe-bran \ Arabic Al-Khalll \,al-ka-'lel\ City (pop., 1997 est.:  119,401) in the West Bank territory, southwest of Jerusalem. It is a sacred  city of Judaism and Islam as the home and burial place (at the Cave of Mach-  pelah) of the patriarch Abraham. King David made Hebron his capital briefly  in the 10th century bc. Various Muslim dynasties ruled the city from ad 635  until after World War I (1914-18), except from 1100 to 1260, when the Cru�  saders controlled it. It was part of the British mandate of Palestine from  1923 until the first Arab-Israeli war in 1948, when it came under the control  of Transjordan (later Jordan). Along with the rest of the West Bank, it was  annexed by Jordan in 1950 but was captured by Israel during the Six- Day  War (1967). It remained under full Israeli administration until 1997, when  Israel and the Palestine Liberation Organization agreed on a partial Israeli  pullout from Hebron and other West Bank cities.</p><p>Hecate Yhe-ko-teX Greek goddess of magic and spells. She probably  originated in Asia Minor. Hesiod held her to be the daughter of the Titan  Perses and represented her as the bestower of wealth and the blessings of  daily life. She witnessed the abduction of Persephone by Hades and assisted  in the search for her. Pillars called Hecataea were erected at doorways  and crossroads to ward off evil spirits. She was sometimes depicted as  three bodies back to back, so that she could look in all directions at a  crossroads.</p><p>Hecatompylos \ I he-k3-'tam-p3- l las\ Ancient city, western Khorasan,  Iran.

He worked for Chicago newspapers 1910-22; at the Daily News  he perfected a type of human-interest sketch that was widely emulated.  Later he divided his time between New York and Hollywood. With Charles  MacArthur he wrote the plays The Front Page (1928), which influenced  both the public�s and the newspaper industry�s ideas about the newspa�  per world; Twentieth Century (produced 1932); and Ladies and Gentle�  men (produced 1939). His film scripts, often written with MacArthur,  include Gunga Din (1938), Wuthering Heights (1939), Spellbound (1945),  and Notorious (1946).</p><p>Heckman, James J. (b.

Heckman studied mathematics at  Colorado College (B.A. 1965) and economics at Princeton University  (M.A. 1968, Ph.D. 1971). He taught at Columbia University (1970-74)  and the University of Chicago (1973- ). The Heckman correction, a two-  step statistical approach, offers a means of addressing errors in statistical  sampling. He received the John Bates Clark medal from the American  Economics Association in 1983.</p><p>Heckscher Vhek-shorX, Eli Filip (b. Nov. 24, 1879, Stockholm,  Swed.�d. Nov. 26, 1952, Stockholm) Swedish economist and economic  historian. He taught at the Stockholm School of Economics from 1909  and was a founder and director of the Stockholm Institute for Economic  History. He wrote mainly on economic history, producing such works as  The Continental System (1922) and Mercantilism (1935). He originated  the concept of commodity points, which limit the fluctuation of paper  currencies, and argued in favour of free trade, asserting that differing pro�  ductive factors were responsible for differing commodities trading advan�  tages among nations. This hypothesis, expanded on by his student Bertil  Ohlin (1899-1979), is now known as the Heckscher-Ohlin theory.</p><p>Hector In Greek legend, the eldest son of Priam and Hecuba, the husband  of Andromache, and the chief warrior of the Trojan army. In Homer�s Iliad  he is notable not only for his military prowess but also for his nobility of  character. He was a favorite of Apollo, who helped him slay Achilles�  friend Patroclus in combat; in reprisal, Achilles killed Hector in battle and  dragged his naked body around the walls of Troy.</p><p>Hecuba Vhe-kyo-boV In Greek legend, the wife of the Trojan king Priam  and mother of Hector. At the end of the Trojan War she was taken pris�  oner. According to Euripides, her youngest son, Polydorus, had been placed  in the care of Polymestor, king of Thrace. When she arrived in Thrace,</p><p>she learned that Polydorus had been murdered. In revenge, she blinded  Polymestor and killed his two sons. In other versions of the legend, she  was later turned into a dog, and her grave beside the Hellespont became  a landmark for ships.</p><p>hedgehog Any of 14 species of insectivores in the family Erinaceidae.  They eat primarily insects and other arthropods but will also eat plant  material. The nine species of spiny hedgehogs have short, barbless spines  on the back, a round body, small head, pointed face, and little or no tail.  Species range from 4 to 17 in. (10 to 44 cm) long. Spiny hedgehogs are  native to Great Britain, northern Africa, and Asia; one species was intro�  duced into New Zealand. The five species of gymnure, or hairy hedge�  hog, are Asian. They have coarse guard hairs but no spines and are  extremely malodorous. The common gymnure may be 18 in. (46 cm) long  and have a 12-in. (30-cm) tail. See also porcupine.</p><p>hedgerow Fence or boundary formed by a dense row of shrubs or low  trees. Hedgerows enclose or separate fields, protect the soil from wind  erosion, and serve to keep cattle and other livestock enclosed. To lay a  hedge, the trunks of closely planted saplings of species suitable for hedge�  rows (e.g., hawthorn) are cut a good portion of the way through and the  sapling laid down on the ground. New growth rises vertically, forming an  impenetrable mesh of branches. In Britain, hedgerows have been a fea�  ture of the countryside since the enclosure movement and provide a habi�  tat for numerous songbirds and small animals. As large-scale mechanized  farming has become dominant, hedgerows are being removed to combine  small fields into larger ones.</p><p>hedging Method of reducing the risk of loss caused by price fluctua�  tion. It consists of the purchase or sale of equal quantities of the same or  very similar commodities in two different markets at approximately the  same time, with the expectation that a future change in price in one mar�  ket will be offset by an opposite change in the other market. For example,  a grain-elevator operator may agree to buy a ton of wheat and at the same  time sell a futures contract for the same quantity of wheat; when the wheat  is sold, he buys back the futures contract. If the grain price has dropped,  he can buy back the futures contract for less than he sold it for; his profit  from doing so will be offset by his loss on the grain. Hedging is also com�  mon in the securities and foreign-exchange markets. See also stock option.</p><p>Heeger, Alan J. (b. Jan. 22, 1936, Sioux City, Iowa, U.S.) U.S. chem�  ist. He received a Ph.D. from the University of California at Berkeley in  1961. With Alan G. MacDiarmid and Shirakawa Hideki, Heeger determined  that certain plastics can be chemically modified to conduct electricity  almost as readily as metals. The finding led to the discovery of other con�  ductive polymers and contributed to the emerging field of molecular elec�  tronics. Heeger, who taught at several institutions, founded the UNIAX  Corp. in 1990. In 2000 he shared the Nobel Prize for Chemistry with  MacDiarmid and Shirakawa.</p><p>Hefei Vh3-'fa\ or Ho-fei Vho-'fa \ formerly Luzhou or Lu-chou City  (pop., 1999 est.: 1,000,655), central China.

In  1953 he founded Playboy , a magazine for men. Playboy's, intellectually  respectable articles and its forthright philosophy of hedonism made it a  seminal influence on the �sexual revolution� of the 1960s. Hefner later  expanded his enterprise into nightclubs and other entertainment media.</p><p>Hegel Vha-goU, Georg Wilhelm Friedrich (b. Aug. 27, 1770, Stutt�  gart, Wiirttemberg�d. Nov. 14, 1831, Berlin) German philosopher. After  working as a tutor, he was headmaster of the gymnasium at Niirnberg  (1808-16); he then taught principally at the University of Berlin (1818�  31). His work, following on that of Immanuel Kant, Johann Gottlieb Fichte,  and F.W. Schelling, marks the pinnacle of post-Kantian German idealism.  Inspired by Christian insights and possessing a fantastic fund of concrete  knowledge, Hegel found a place for everything�logical, natural, human,  and divine�in a dialectical scheme that repeatedly swung from thesis to  antithesis and back again to a higher and richer synthesis. His panoramic  system engaged philosophy in the consideration of all the problems of</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>856 I Hegelianism &#x25BA; Heimlich maneuver</p><p>history and culture, none of which could any longer be deemed foreign  to its competence. At the same time, it deprived all the implicated ele�  ments and problems of their autonomy, reducing them to symbolic mani�  festations of the one process, that of the Absolute Spirit�s quest for and  conquest of its own self. His influence has been as fertile in the critical  reactions he precipitated as in his positive impact. His principal works are  Phenomenology of Mind (1807), Encyclopedia of the Philosophical Sci�  ences (1817), and Philosophy of Right (1821). He is regarded as the last  of the great philosophical system builders. See also Hegelianism.</p><p>Hegelianism Mii-'ga-le-o-.ni-zomX Diversified philosophical movement  that developed out of G. W. F. Hegel�s system of thought. Four stages can  be distinguished. The first consists of the Hegelian school in Germany in  the period 1827-50. The school divided into three currents. The right, or  �Old Hegelians,� sought to uphold Hegelianism�s compatibility with  evangelical orthodoxy and conservative political policies. The left, or  �Young Hegelians,� interpreted Hegel�s identification of the rational with  the real in a revolutionary sense. The center preferred to fall back on  interpretations of the Hegelian system in its genesis and significance. In  the second phase (1850-1904), usually called Neo-Hegelian, the works of  the center played a preponderant role. After Wilhelm Dilthey discovered  unpublished papers from Hegel�s youth in the early 20th century, there  arose in Germany yet another movement; this third phase, the Hegel  renaissance, stressed the reconstruction of the genesis of Hegel�s thought.  In the fourth stage, after World War II, the revival of Marxist studies in  Europe finally thrust into the foreground the value of the Hegelian heri�  tage for Marxism.</p><p>Hegira See Hijrah  Heh See Hu, Sia, and Heh</p><p>Hei-lung-chiang See Heilongjiang</p><p>Heian \'ha-'an\ period (794-1185) Period of Japanese history named  for the capital city of Heian-kyo (Kyoto). It is known mainly for the flour�  ishing culture of the court aristocracy, which devoted itself to the pursuit  of aesthetic refinement as displayed in poetry and calligraphy. Murasaki  Shikibu�s contemporaneous novel The Tale ofGenji depicts that life. A less  refined view of Heian Japan is offered in one portion of Konjaku monoga-  tari, a collection of stories and folktales. Aesthetics were also emphasized  by the Shingon Buddhist sect, which, along with the broadly syncretic  Tendai (Chinese Tiantai) sect, replaced the earlier Nara Buddhist sects in  influence. Pietism gained popularity in the late Heian, leading to the  founding of the Pure Land sect by Honen. Politically, civilians dominated  until 1156, when warriors were called in to settle a political dispute and  never left. A brief period of rule by the Taira military clan ensued.

May 26,</p><p>1976, Messkirch, W.Ger.) German  philosopher. He taught at the univer�  sities of Marburg (1923-27) and  Freiburg (1927�44). In 1927 he pub�  lished his magnum opus, Being and  Time. It strongly influenced Jean-  Paul Sartre and other existentialists,  and, despite Heidegger�s protesta�  tions, he was classed as the leading  atheistic existentialist. His declared  purpose in the work was to raise  anew the question of the meaning of  being. His preliminary analysis of  human existence ( Dasein , or �being-  there�) employed the method of phe�  nomenology. In the early 1930s his  thought underwent a Kehre (�turning  around�), which some have seen as  an abandonment of the problem of  Being and Time. Heidegger joined  the Nazi Party in 1933 and supported  Hitler�s policies as rector of Freiburg (1933-34) and less actively through  the end of the war. His complicity with the Nazis, which he never pub�  licly disavowed, has prompted debates about whether his philosophy is  inherently �totalitarian.� Heidegger�s work strongly influenced hermeneu�  tics and POSTSTRUCTURALISM.</p><p>Heidelberg Vhld^T-.borkX City (pop., 2002 est.: 141,509), southwest�  ern Germany, situated on the Neckar River.

His first book of poems, Pilgrimage and Wander Years  (1888), drew on his years living in southern Europe and the Middle East  and was an immediate success. With his essay �Renaissance� (1889), he  became a leader of the opposition in Sweden to naturalism, calling for a  rebirth of the literature of fantasy, beauty, and nationalism. Many of the  poems he wrote in this vein are translated in Sweden�s Laureate (1919).  He also wrote historical fiction, including The Charles Men (1897-98)  and The Tree of the Folkungs (1905-07).

From 1909 to 1914, although  it was illegal for a Jew to live in St. Petersburg, he studied there with  Leopold Auer (1845-1930). He immigrated to the U.S. in 1917, where  for many years he performed in a trio with Artur Rubinstein and Gregor  Piatigorsky (1903-76).

Born of Jewish parents, he converted to Protestantism to  enter careers that he never actually pursued. He established his interna�  tional literary reputation with The Book of Songs (1827), a collection of  bittersweet love poems. His prose Pictures of Travel, 4 vol. (1826-31),  was widely imitated. After 1831 he lived in Paris. His articles and stud�  ies on social and political matters, many critical of German conservatism,  were censored there, and German spies watched him in Paris. His second  verse collection, New Poems (1844), reflected his social engagement. His  third, Romanzero (1851), written while suffering failing health and finan�  cial reverses, is notably bleak but has been greatly admired. He is regarded  as one of Germany�s greatest lyric poets, and many of his poems were  set as songs by such composers as Franz Schubert, Robert Schumann, and  Johannes Brahms.</p><p>Heinlein \'hln-lln\, Robert A(nson) (b.

Most ancient religions included the  concept of a place that divided the good from the evil or the living from  the dead (e.g., the gloomy subterranean realm of Hades in Greek religion,  or the cold and dark underworld of Nilfheim or Hel in Norse mythology).  The view that hell is the final dwelling place of the damned after a last  judgment is held by Zoroastrianism, Judaism, Christianity, and Islam. The  Jewish concept of Gehenna as an infernal region of punishment for the  wicked was the basis for the Christian vision of hell as the fiery domain  of Satan and his evil angels and a place of punishment for those who die  without repenting of their sins. In Hinduism hell is only one stage in the  career of the soul as it passes through the phases of reincarnation. The  schools of Buddhism have varying conceptions of hell, usually entailing  some kind of punishment or purgatory. In Jainism, hell is a purgatory in  which sinners are tormented by demons until the evil of their lives has  been exhausted.</p><p>hellbender Salamander ( Cryptobranchus alleganiensis, family Crypto-  branchidae) found in swift-flowing rivers in the eastern and central U.S.  It grows to about 25 in.

Alexander and his successors established  Greek monarchies that controlled the area from Greece to Afghanistan. The  Macedonian Antigonid kingdom, the Middle Eastern Seleucid kingdom, and  the Egyptian Ptolemaic kingdom spread Greek culture, mixed Greek and  non-Greek populations, and fused Greek and Oriental elements. They pro�  duced effective bureaucracies and a common, creative culture based at  Alexandria. A great flowering of the arts, literature, and science occurred  particularly in the period 280-160. The decline of the Hellenic states  occurred as Rome gained strength and won wars against Macedonia and  against Mithradates VI Eupator, turning the kingdoms and their allies into  Roman provinces.

They were state-owned serfs or slaves  who worked the land to feed and clothe the Spartan population, whom they  vastly outnumbered. Their masters could not free them or sell them. The  Spartans lived in constant fear of a helot revolt and annually declared war  on them to legally keep them in place by force. During wartime, helots  attended their masters on campaigns, serving as troops and as rowers in the  fleet. The Messenian helots were liberated c. 370 bc, those in Laconia not  until the 2nd century bc.</p><p>Helper, Hinton Rowan (b. Dec. 27, 1829, Davie county, N.C.,  U.S.�d. March 9, 1909, Washington, D.C.) U.S. antislavery writer. His  1857 work The Impending Crisis of the South argued that slavery harmed  nonslaveholding whites and inhibited economic progress in the South. It  became influential in the antislavery movement in the North; in the South  it caused a furor and was banned in several states. For his safety Helper  moved to New York City. After the American Civil War, Helper wrote three  bitter racist tracts advocating the deportation of blacks to Africa or Latin  America.</p><p>Helpmann, Sir Robert (Murray) (b. April 9, 1909, Mount Gam-  bier, Austl.�d. Sept. 28, 1986, Sydney) Australian ballet dancer, chore�  ographer, actor, and director. After dancing and acting in Australia, in  1933 he went to London to study, joining the Vic-Wells Ballet (later Royal  Ballet), where he became a regular partner of Margot Fonteyn. His own  ballets included Hamlet (1942), Miracle in the Gorbals (1944), and Adam  Zero (1946). He danced in the films The Red Shoes and Tales of Hoff�  mann, acted in many Shakespeare plays, and also directed several plays.  He was artistic codirector of the Australian Ballet (1965-76).</p><p>Helsinki Swedish Helsingfors City (pop., 2002 est.: city, 559,718;  metro, area, 964,953), capital of Finland. Located in southern Finland on a  peninsula with natural harbours, it is the country�s leading seaport. Often  called the �white city of the north� because many of its buildings are made  of a local light-coloured granite, it was founded by Sweden in 1550 and  moved to its present site in 1640. With Finland it came under Russian rule  in 1808. Under Russian Tsar Alexander I, Helsinki became the capital of the  grand duchy of Finland in 1812, and it remained as the capital of the coun�  try. In 1917 Finland declared independence from Russia, and a brief but  bloody civil war ensued in the capital. In subsequent decades it developed  into an important trade centre. It was damaged by Russian bombing during  World War II (see Russo- Finnish War) but was rebuilt. It was the site of a  1975 international diplomatic conference (see Helsinki Accords). Helsinki  has theatres, an opera and ballet company, and several symphony orches�  tras, and it hosted the 1952 Olympic Summer Games.</p><p>Helsinki Accords International agreement signed in 1975, designed to  reduce tension between the Soviet and Western blocs. It was an attempt  to secure common acceptance of the post-World War II status quo in  Europe, including the division of Germany. The accords, signed by all the  countries of Europe (except Albania) as well as the U.S. and Canada, were  nonbinding and lacked treaty status. They were sought by the Soviet  Union to gain implicit recognition of its postwar hegemony in eastern  Europe. In return, the U.S. and its western European allies pressed for  respect for human rights and cooperation in economic, scientific, and  other humanitarian areas. Follow-up meetings in Belgrade (1977-78),  Madrid (1980-83), and Ottawa (1985) were marked by strong criticism  of Soviet human-rights abuses and by Soviet counteraccusations. A 1990  conference in Paris formally ended the Cold War and recognized German  reunification.</p><p>Helvetic Republic Republic founded in March 1798, constituting the  greater part of Switzerland, after it had been conquered by France in the  French Revolutionary Wars. The government was patterned after that of  the Directory in France. Delegates called on Napoleon to mediate in fac�  tional disputes, and in 1803 he substituted a new Swiss Confederation for  the republic, forcing it into close association with France.</p><p>Helvetius \el-vas-'yiEs\, Claude-Adrien (b. Jan. 26, 1715, Paris,  France�d. Dec. 26, 1771, Vore, Collines des Perches) French philoso�  pher, controversialist, and patron of the philosophes. He is remembered for  his hedonism, his criticism of the religious foundations of ethics, and his  educational theory. His On the Mind (1758) immediately became notori�  ous for its attack on all forms of morality based on religion. He held that  all men are equally capable of learning�a belief that led him to argue  against the position taken by Jean-Jacques Rousseau in his work Emile �  and that through education all human problems could be solved.</p><p>Hemacandra N.ha-mo-'chon-droV orig. Candradeva (b. 1088,  Dhandhuka, Gujarat, India�d. 1172, Gujarat) Sage of Jainism. His birth is  said to have been attended by auspicious omens, and he was educated by  Jain priests. Ordained in 1110, he became an adviser to King Kumarapala  in 1125, and by converting the king he firmly entrenched Jainism in  Gujarat. His many writings include works on almost every branch of Indian  philosophy and the sciences as well as literary writings such as his Sanskrit  epic, Lives of the Jain Elders. In accordance with Jain tradition, he fasted  to death.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>860 I hemangioma &#x25BA; hemp</p><p>hemangioma V.he-.man-je-'o-msN Congenital benign tumour made of  blood vessels in the skin. Capillary hemangioma (nevus flammeus, port-  wine stain), an abnormal mass of capillaries on the head, neck, or face, is  pink to dark bluish-red and even with the skin. Size and shape vary. It  becomes less noticeable or disappears with age. Immature hemangioma  (hemangioma simplex, strawberry mark), a reddish nub of dilated small  blood vessels, enlarges in the first six months and may become ulcerated  but usually recedes after the first year. Cavernous hemangioma, a rare, red-  blue, raised mass of larger blood vessels, can occur in skin or in mucous  membranes, the brain, or the viscera. Fully developed at birth, it is rarely  malignant. Hemangiomas can often be removed by cosmetic surgery.</p><p>hematite Vhe-mo-.tltV or haematite Heavy and relatively hard oxide  mineral, ferric oxide (Fe 2 0 3 ), that constitutes the most important iron ore  because of its high iron content and its abundance. Much hematite (from  the Greek word meaning �blood,� for its red colour) occurs in a soft, fine�  grained, earthy form called red ocher or ruddle. Red ocher is used as a  paint pigment; a purified form, rouge, is used to polish plate glass. The  world�s largest production comes from the Hamersley Range in western  Australia.</p><p>hematology \ l he-m3-'ta-l3-je\ Branch of medicine concerned with the  nature, function, and diseases of the blood. It covers the cellular and serum  composition of blood, the coagulation process, blood-cell formation,  hemoglobin synthesis, and disorders of all these. Marcello Malpighi, in the  17th century, was the first to examine red blood cells (erythrocytes). In the  18th century, the British physiologist William Hewson (1739-74) exam�  ined the lymphatic system and blood clotting. In the 19th century, the bone  marrow was recognized as the site of blood-cell formation, and diseases  of the blood such as anemia and leukemia were identified. In the early 20th  century, the ABO blood-group system was discovered and the role of nutri�  tion in blood formation was studied. Post-World War II studies have  delved further into the nature of blood diseases and improved treatments  and have examined hemoglobin synthesis and the role of platelets in blood  coagulation.</p><p>hematuria \,he-m3- , tur-e-9\ Blood in the urine. It usually indicates  injury or disease of the kidney or another structure of the urinary system  or possibly, in males, the reproductive system. It may result from infec�  tion, inflammation, tumours, kidney stones, or other disorders. How the  blood looks and when it appears in the urine stream reflect whether it  originates in the urethra, the bladder, or the kidney.</p><p>Hemingway, Ernest (Miller) (b. July 21, 1899, Cicero [now in Oak  Park], Ill., U.S.�d. July 2, 1961,</p><p>Ketchum, Idaho) U.S. writer. He  began work as a journalist after high  school. He was wounded while serv�  ing as an ambulance driver in World  War I. One of a well-known group of  expatriate writers in Paris, he soon  embarked on a life of travel, skiing,  fishing, and hunting that would be  reflected in his work. His story col�  lection In Our Time (1925) was fol�  lowed by the novel The Sun Also  Rises (1926). Later novels include A  Farewell to Arms (1929) and To  Have and Have Not (1937). His life�  long love for Spain (including a fas�  cination with bullfighting) led to his  working as a correspondent during  the Spanish Civil War, which  resulted in the novel For Whom the  Bell Tolls (1940). Other short-story  collections include Men Without  Women (1927), Winner Take Nothing  (1933), and The Fifth Column  (1938). He lived primarily in Cuba  from c. 1940, the locale of his novella The Old Man and the Sea (1952,  Pulitzer Prize). He was awarded the Nobel Prize for Literature in 1954.  He left Cuba shortly after its 1959 revolution; a year later, depressed and  ill, he shot himself. The succinct and concentrated prose style of his early  works strongly influenced many British and American writers for decades.</p><p>hemispheric asymmetry See laterality</p><p>hemlock Any of 10 species of coniferous evergreen trees that make up  the genus Tsuga, in the pine family, native to North America and central  and eastern Asia. Some are important timber trees, and many are popular  ornamentals. Other plants commonly called hemlock include ground hem�  lock (see yew) and poison hemlock and water hemlock (parsley family). A  true hemlock is a tall, pyramidal tree with purplish or reddish-brown bark,  slender horizontal or drooping branches, and short, blunt leaves that grow  from woody cushionlike structures on the twigs.</p><p>hemodialysis See dialysis</p><p>hemoglobin Vhe-mo-.glo-bonV Protein in the blood of many animals  (in vertebrates it is in red blood cells) that transports oxygen from the lungs  to the tissues. It is bright red when combined with oxygen and purple-  blue in the deoxygenated state. Each molecule is made up of a globin (a  type of protein) and four heme groups. Heme, a complex heterocyclic  compound, is an organic molecule derived from porphyrin with an iron atom  at the centre.

Lack of factor VIII causes classic  hemophilia; other types are caused by deficiency of factor IX or XI. The  first two are transmitted by sex-linked heredity; the third has dominant  inheritance and occurs in females as well as males. Spontaneous bleed�  ing may occur. Even trivial injury can cause life-threatening blood loss.  Drugs can be given to stop bleeding. Heavy blood loss requires blood  transfusions.</p><p>hemorrhage Vhe-mo-rijV Escape of blood from blood vessels into sur�  rounding tissue. When a vessel is injured, hemorrhage continues as long  as the vessel remains open and the pressure in it exceeds the pressure  outside of it. Normally, coagulation closes the vessel and stops the bleed�  ing. Uncontrolled hemorrhage can result from anticoagulant therapy,  hemophilia, or severe blood-vessel damage, leading to excessive blood loss  and shock.</p><p>hemorrhagic X.he-ms-Ta-jikV fever Disease with high fever and hem�  orrhage of internal organs and into the skin. It is caused by several kinds  of virus (of which Ebola, dengue, and yellow fever are the best known),  some carried by ticks, mosquitoes, or animals. Initial symptoms may  include head, muscle, joint, and abdominal pain; nausea and vomiting;  sweating and thirst; and coldlike symptoms. It comes on suddenly and  can cause severe kidney damage.

It is bounded by Shanxi, Hebei,  Shandong, Anhui, Hubei, and Shaanxi. It has an area of 64,500 sq mi  (167,000 sq km), and its capital is Zhengzhou. An early civilization there  gave rise to the Shang dynasty (18th�12th centuries bc). Kaifeng was the  capital of several dynasties in the 10th century ad before becoming the  capital of the Bei (Northern) Song dynasty (960-1127); Zhengzhou then  became the provincial capital. Henan�s principal crop is wheat. Henan has  large deposits of coal, petroleum, and natural gas, which fuel the econo�  mies of its major cities. It is also a railroad transportation hub.</p><p>henbane Plant ( Hyoscyamus niger ) of the nightshade family, native to  Britain and found growing wild in poor soil and on rubbish heaps. It also  occurs in central and southern Europe and from western Asia to India and  Siberia and has long been naturalized in the U.S. The whole plant has a  powerful nauseating odour. Commercial henbane, which consists of the  dried leaves of H. niger and sometimes of H. muticus, of Egypt, yields  three drugs: atropine, hyoscyamine, and scopolamine. Isolated and puri�  fied, these drugs are remedies for spasmodic muscular contractions, ner�  vous irritation, and hysteria.</p><p>Henderson, (James) Fletcher (b. Dec. 18, 1898, Cuthbert, Ga.,  U.S.�d. Dec. 29, 1952, New York, N.Y.) U.S. pianist, arranger, and leader  of one of the most influential big bands in jazz. Henderson formed a dance  band in New York in 1923. The band soon distinguished itself in two  ways: the engagement of Louis Armstrong as principal soloist placed  greater emphasis on swinging improvisation and the arrangements by  Henderson and Don Redman (1900-64) codified the roles of the sections  within the ensemble to replace the collective improvisation of early jazz  groups. Nearly all big bands subsequently followed their example. A poor  businessman, he was forced to dissolve his band several times, but his  arrangements played a key role in the success of Benny Goodman in the  late 1930s and provided a template for much of the music of the swing  era.</p><p>Henderson, Rickey in full Rickey Henley Henderson (b. Dec.  25, 1958, Chicago, Ill., U.S.) U.S. baseball player. Henderson made his  major league debut in 1979 with the Oakland Athletics. The following  year he became one of only three players to steal 100 bases. It was the  first of seven consecutive seasons in which Henderson led the American  League in stolen bases, and his 130 in 1982 set a major league record.  Considered one of the game�s greatest leadoff hitters, he was named the  American League�s Most Valuable Player in 1990. The following year he  stole the 939th base of his career to top Lou Brock�s mark. With the San  Diego Padres in 2001, he broke Babe Ruth�s lifetime record for walks  (2,062) and Ty Cobb�s career record for runs (2,245). Henderson helped  the Athletics and the Toronto Blue Jays win World Series in 1989 and  1993, respectively.</p><p>Hendricks, Thomas A(ndrews) (b. Sept. 7, 1819, near Zanesville,  Ohio, U.S.�d.

He  practiced law in Indiana before serving in the U.S. House of Represen�  tatives (1851-55) and Senate (1863-69); he was later governor (1873�  77). Though loyal to the Union, he opposed many aspects of the Union�s  military effort during the American Civil War; he also opposed the Recon�  struction program imposed on the South after the war. He favoured  leniency toward white supremacists in the South and opposed all legis�  lation aimed at assisting freedmen. He was the Democratic Party nomi�  nee for vice president in 1876 (as the running mate of Samuel Tilden) and  again in 1884, when he was elected with Grover Cleveland. He died shortly  after taking office.</p><p>Hendrix, Jimi byname of James Marshall Hendrix (b. Nov. 27,  1942, Seattle, Wash., U.S.�d. Sept. 18, 1970, London, Eng.)

He served as an army paratrooper and later toured as gui�  tarist for Little Richard and others. In 1966 he moved to London and formed  a trio, The Jimi Hendrix Experience, which rapidly became popular in  Europe. His sensational appearance at the Monterey Pop Festival in 1967  and the success that year of the album Are You Experienced? lifted him</p><p>to instant stardom, and his subsequent albums were among the most influ�  ential of the 1960s.

After a  revolt broke out in the Sudetenland in 1938, the government suspended  his party for treasonable activities, and Henlein fled to Germany. After  the Munich agreement ceded the Sudetenland to Germany, he was  appointed commissioner for the territory.

As a portrait painter he dem�  onstrated facile brushwork, lively colours, and an ability to catch fleeting  gestures and expressions. He is best remembered as a teacher, principally  at New York�s Art Students League (1915-28), where he became one of  the most influential art teachers in the U.S. and a powerful force in turn�  ing young artists away from academicism and toward the rich subject  matter of modern city life.

Sept. 10, 1669, Chateau de Colombes, near Paris) French-bom  English queen, wife of Charles I and mother of Charles II and James II. The  daughter of Henry IV of France and Marie de Medicis, she was no stranger  to political intrigue. By openly practicing Roman Catholicism at court,  she alienated many of Charles�s subjects. As the English Civil Wars  approached, she sought without success to instigate a military coup to  overthrow the Parliamentarians. Her further efforts to enlist support for  Charles from the pope, the French, and the Dutch infuriated many  Englishmen. Deterioration of the Royalist position caused her to flee to  France in 1644, and she never again saw her husband, who was executed  in 1649.</p><p>Henry I known as Henry Beauclerc \'bo-kler\ (French: "Good  Scholar") (b. 1069�d. Dec. 1, 1135, Lyons-la-Foret, Normandy) King  of England (1100-35) and ruler of Normandy (1106-35). The youngest  son of William I, he became king on the death of William II. His eldest  brother, Robert Curthose (Robert II), returned from the First Crusade to  claim the English throne in 1101; Henry placated him by giving him Nor�  mandy, but Robert ruled it badly, and in 1106 Henry seized Normandy  and imprisoned his brother. Henry quarreled with Anselm of Canterbury  over the issue of investiture (see Investiture Controversy), but they were  reconciled in 1107. He maintained control of Normandy, despite attacks  by Robert�s son, and named his daughter Matilda his heir.</p><p>Henry II known as Henry of Anjou Van-jii\ or Henry Plan-  tagenet \plan-'ta-j3-n3t\ (b. 1133, Le Mans, Maine�d. July 6, 1189,  near Tours) Duke of Normandy (from 1150), count of Anjou (from 1151),  duke of Aquitaine (from 1152), and king of England (from 1154). The son  of Matilda and grandson of Henry I, he gained vast territories in France  by marrying Eleanor of Aquitaine (1152). He invaded England, and, in  settlement of the war, King Stephen named Henry as heir (1153). As king,  Henry extended his holdings in northern England and western France,  strengthened royal administration, and reformed the court system. His  attempt to assert royal authority at the expense of the church (see Con�  stitutions of Clarendon) led to a quarrel with the archbishop of Canter�  bury, his former close friend St. Thomas Becket, which ended with  Becket�s murder and Henry�s subsequent penance at Canterbury (1174).  His reign was plagued by disputes among family members, especially  struggles for precedence among his sons, including Richard I (the Lion-  heart) and John (Lackland). Richard allied with Philip II of France to drive  Henry from the throne in 1189.</p><p>Henry II French Henri \a n -'re\ orig. due (duke) d'Orleans (b.</p><p>March 31, 1519, Saint-Germain-en-Laye, near Paris, Fr.�d.

The second son of Francis I, he  had strong differences with his father, accentuated by the rivalry between  their mistresses and by Henry�s support of the constable Anne, due de  Montmorency (1493-1567). Though he continued many of his father�s  policies, Henry raised the Catholic House of Guise to favour, and he vig�  orously suppressed Protestantism within his kingdom. He made a num�  ber of administrative reforms. In foreign affairs Henry continued his  father�s warfare against Emperor Charles V until 1559, when he signed  the Treaty of Cateau-Cambresis. The treaty was to be cemented by the mar�  riage of Henry�s daughter to Philip II of Spain; during the festivities he was  hit in the head by a lance, and he died from the wound.</p><p>Henry II or St. Henry German Heinrich (b.

He alienated the barons by his indifference to tradition and his  agreement to supply Innocent IV with funds in exchange for the Sicilian  crown. The barons forced him to accept the Provisions of Oxford, but  Henry renounced the agreement in 1261. His former favourite, Simon de  Montfort, led a rebellion in 1264, defeating and capturing the king. Hen�  ry�s son Edward (later Edward I) turned the tables a year later, and Henry,  weak and senile, allowed Edward to take charge of the government.</p><p>Henry III French Henri orig. duke d'Anjou (b. Sept. 19, 1551,  Fontainebleau, France�d. Aug. 2, 1589, Saint-Cloud) King of France  (1574-89). The third son of Henry II and Catherine de Medicis, he com�  manded the royal army against the Huguenots in the Wars of Religion. He  was crowned king after the death of his brother Charles IX. During the  continuing civil wars he made concessions to the Huguenots, causing the  Roman Catholics to form the Holy League. The Catholics were further  alarmed in 1584 when the Protestant Henry of Navarra (later Henry IV)  became heir to the throne. Henry III tried to placate the Holy League, but  he was forced by a mob to flee Paris. In 1588 he had the Catholic leaders  Henry, 3rd duke de Guise, and Cardinal Louis II de Lorraine assassinated.  In 1589 Henry was himself assassinated by a fanatical Jacobin friar.</p><p>Henry III German Heinrich (b. Oct. 28, 1017�d. Oct. 5, 1056, Pfalz  Bodfeld, near Goslar, Saxony) Duke of Bavaria (as Henry VI, 1027�41),  duke of Swabia (as Henry I, 1038�45), German king (1039-56), and  emperor (1046-56). He gained sovereignty over Bohemia and Moravia  and arranged the election of Pope Clement II, who crowned him emperor.  The last emperor to dominate the papacy, Henry appointed three more  popes in succeeding years. He championed the church reform advocated  by the monasteries of Cluny and Gorze. He was nearly deposed in a revolt  (1054-55), and in his later years his influence faltered in northeastern  Germany, Hungary, southern Italy, and Lorraine.</p><p>Henry IV orig. Henry Bolingbroke (b. April? 1366, Bolingbroke  Castle, Lincolnshire, Eng.�d. March 20, 1413, London) King of England  (1399-1413), first of three 15th-century monarchs of the house of Lan�  caster. Son of John of Gaunt, he initially supported Richard II against the  duke of Gloucester but turned against him after being banished in 1398.  He invaded England in 1399, forcing Richard�s surrender and abdication.  Having gained the crown by usurpation, he successfully consolidated his  power in the face of repeated uprisings of powerful nobles. However, he  failed to subdue the Welsh under Owen Glendower, was defeated by the  Scots, and was unable to overcome the fiscal and administrative weak�  nesses that contributed to the eventual downfall of the Lancastrian  dynasty. He was succeeded by his son, Henry V.</p><p>Henry IV or Henry of Navarra French Henri de Navarre (b.</p><p>Dec. 13, 1553, Pau, Bearn, Navarra�d. May 14, 1610, Paris) First Bour�  bon king of France (1589-1610) and king of Navarra (as Henry III, 1572�  89), one of the most popular figures in French history. Henry was brought  up as a Protestant and received his military training from the Huguenot  leader Gaspard II de Coligny in the Wars of Religion. He married Margaret  of Valois in 1572; the marriage provided the opportunity for the Massa�  cre of Saint Bartholomew's Day six days later. Henry was held at the French  court from 1572 to 1576, when he escaped to join the forces against Henry  III. He fought the War of the Three Henrys and prevailed as unrivaled leader.  He became king after Henry III was assassinated in 1589, but was forced  to fight the Holy League for nine years to secure his kingdom. In 1593 he  converted to Roman Catholicism to remove all pretext for resistance to  his rule. He entered Paris amid cheers in 1594, but he had to wage war  (1595-98) against Spain, which supported the remaining resistance to him  in France. Henry signed the Edict of Nantes in 1598, ending 40 years of  civil war. With the aid of his ministers, including the duke de Sully, Henry  brought order and new prosperity to France. His earlier marriage was  annulled, and in 1600 he married Marie de Medicis. In 1610 he was assas�  sinated by a fanatical Roman Catholic.</p><p>Henry IV German Heinrich (b. Nov. 11, 1050, Goslar?, Saxony�d.  Aug. 7, 1106, Liege, Lorraine) Duke of Bavaria (1055-61), German king  (1054-1106), and emperor (1084-1105/6). He succeeded to the German</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Henry V &gt; Henry I 863</p><p>throne at age six; his pious and unworldly mother was regent until 1062,  and Henry gained control of the government upon reaching his majority  in 1065. His reassertion of royal rights provoked rebellion in Saxony  (1073-75). He engaged in a long struggle with Pope Gregory VII over the  issues of obedience to papal commands and lay investiture (see Investiture  Controversy). Gregory excommunicated him and absolved his subjects of  their oaths of loyalty. Seeking absolution, Henry was forced to cross the  Alps in winter and, according to tradition, stand barefoot in the snow three  days before the castle at Canossa, where the pope was staying, before the  latter would rescind his order. The German princes deserted Henry (1077)  and elected Rudolf I as king. In 1080 Gregory excommunicated Henry  again and recognized Rudolf. Henry responded by conquering Rome  (1084) and installing the antipope Clement III. In his last years his sons  Conrad and Henry led rebellions against his rule.</p><p>Henry V (b. Sept. 16?, 1387, Monmouth, Monmouthshire, Wales�d.  Aug. 31, 1422, Bois de Vincennes, Fr.) King of England (1413�22) of the  House of Lancaster. The eldest son of Henry IV, he fought Welsh rebels  (1403-08). As king he harshly suppressed a Lollard uprising (1414) and  a Yorkist conspiracy (1415). He claimed extensive lands in France and  launched an invasion (1415), and his stunning victory at the Battle of  Agincourt made England one of the greatest powers in Europe. His con�  tinuing victories forced the French to sign the Treaty of Troyes (1420),  in which Henry was named heir to the French throne and regent of France.  He married Catherine, daughter of the French king, but died of camp fever  before he could return home.</p><p>Henry VI (b. Dec. 6, 1421, Windsor, Berkshire, Eng.�d. May 21/22,  1471, London) King of England (1422-61, 1470-71). Son of Henry V, he  became king as an infant, and grew up a pious and studious recluse, who  suffered episodes of mental instability. England�s political affairs were  dominated by the rivalries of a series of overpowerful ministers of the  houses of Lancaster and York, and Henry�s incapacity for government  became one of the causes of the Wars of the Roses. In 1461 a Yorkist was  proclaimed Edward IV. Henry fled, but he returned in 1464 in an unsuc�  cessful Lancastrian rising and was eventually captured and imprisoned.  After a quarrel in the York faction, he was restored to the throne in 1470.  Edward fled but soon returned to defeat and kill the earl of Warwick and  regain the throne. The death in battle of Prince Edward, Henry�s heir,  sealed Henry�s fate, and he was murdered in the Tower of London soon  afterward.</p><p>Henry VI German Heinrich (b. autumn 1165, Nijmegen, Neth.�d.  Sept. 28, 1197, Messina, Italy) German king (1169-97) and Holy Roman  emperor (1191-97) of the Hohenstaufen dynasty who acquired the king�  dom of Sicily by marriage. Crowned king in 1169, Henry took over gov�  ernment of the Holy Roman Empire when his father, Frederick I  Barbarossa, embarked on a Crusade to the Holy Land in 1189. Soon after  his coronation he faced revolts by Henry the Lion in Germany and Tan-  cred in Sicily, but he succeeded in making peace in 1194. His efforts to  make the imperial crown hereditary were unsuccessful, but his son Fre�  derick II would become emperor after the death of Henry�s eventual suc�  cessor, the Welf ruler, Otto IV.</p><p>Henry VII orig. Henry Tudor, earl of Richmond (b. Jan. 28,  1457, Pembroke Castle, Pembrokeshire, Wales�d. April 21, 1509, Rich�  mond, Surrey, Eng.) King of England (1485-1509) and founder of the  Tudor dynasty. As earl of Richmond and a kinsman in the House of Lan�  caster, he fled to Brittany after the triumph of the Yorkist forces in 1471.  He later returned to England, rallied the opponents of Richard III, and  defeated him at the Battle of Bosworth Field (1485). He married Elizabeth  of York and ended the Wars of the Roses, though Yorkist plots continued.  He made peace with France (1492), the Netherlands (1496), and Scotland  (1499) and used his children�s marriages to build European alliances. His  commercial treaties and promotion of trade made England wealthy and  powerful. He was succeeded by his son Henry VIII.</p><p>Henry VII German Heinrich (b. c. 1269/74, Valenciennes,  Hainaut�d. Aug. 24, 1313, Buonconvento, near Siena, Italy) Count of  Luxembourg (as Henry IV), German king (1308-13), and Holy Roman  Emperor (1312-13). The first German king of the House of Luxembourg,  he strengthened the position of his family by obtaining the throne of  Bohemia for his son. He became ruler of Lombardy (1311) but faced con�  flicts between Guelphs and Ghibellines. Though crowned emperor at Rome,  he was unable to subdue Florence or Naples, and he failed in his attempt  to bind Italy firmly to the empire.</p><p>Henry VIII (b. June 28,1491, Greenwich, near London, Eng.�d. Jan. 28,  1547, London) King of England  (1509-47). Son of Henry VII, Henry  married his brother�s widow, Cathe�  rine of Aragon (the mother of Mary I),  soon after his accession in 1509. His  first chief minister, Thomas Cardinal  Wolsey, exercised nearly complete  control over policy in 1515-27. In  1527 Henry pursued a divorce from  Catherine to marry Anne Boleyn, but  Pope Clement VII denied him an  annulment. Wolsey, unable to help  Henry, was ousted. The new minister,</p><p>Thomas Cromwell, in 1532 initiated a  revolution when he decided that the  English church should separate from  Rome, allowing Henry to marry  Anne in 1533. A new archbishop,</p><p>Thomas Cranmer, declared the first  marriage annulled. A daughter, Eliza�  beth I, was bom to Anne soon after.</p><p>Becoming head of the Church of  England represented Henry�s major  achievement, but it had wide-ranging  consequences. Henry, once pro�  foundly devoted to the papacy and  rewarded with the title Defender of  the Faith, was excommunicated, and  he was obliged to settle the nature of  the newly independent church. In the  1530s his power was greatly  enlarged, especially by transferring  to the crown the wealth of the monasteries and by new clerical taxes, but his  earlier reputation as a man of learning became buried under his enduring  fame as a man of blood. Many, including St. Thomas More, were killed  because they refused to accept the new order. The king grew tired of Anne,  and in 1536 she was executed for adultery. He immediately married Jane  Seymour, who bore him a son, Edward VI, but died in childbirth. Three  years later, at Cromwell�s instigation, he married Anne of Cleves, but he  hated her and demanded a quick divorce; he had Cromwell beheaded in  1540. By now Henry was becoming paranoid, as well as enormously fat  and unhealthy. In 1540 he married Catherine Howard, but he had her  beheaded for adultery in 1542. In 1542 he waged a financially ruinous war  against Scotland. In 1543 he married Catherine Parr, who survived him. He  was succeeded on his death by his son, Edward.</p><p>Henry, Cape Promontory, at the southern entrance to Chesapeake Bay,  southeastern Virginia, U.S. Located in Virginia Beach city, it is opposite  Cape Charles, to which it is connected by the Chesapeake Bay Bridge  Tunnel.

He observed electromagnetic induc�  tion a year before Michael Faraday announced its discovery. He made  improvements to electromagnets, discovered the laws on which the trans�  former is based, investigated electric discharge, and demonstrated that  sunspots radiate less heat than the general solar surface. In 1846 he  became the first secretary and director of the Smithsonian Institution,  where he organized a corps of volunteer weather observers that led to cre�  ation of the U.S. Weather Bureau. He was a chief technical adviser to  Abraham Lincoln during the Civil War and a primary organizer of the  National Academy of Science.

His  skill as an orator was displayed in the Parson's Cause trial (1763). Elected  to the Virginia House of Burgesses in 1765, he opposed the Stamp Act;  during the next decade he became a leader of the radical opposition to  British rule. He was a founding member of the Committees of Correspon�  dence and a delegate to the Continental Congress. At a Virginia assembly  in 1775 he delivered his famous speech in defense of liberty, which con�  cluded with the words �Give me liberty or give me death.� He helped  draft the state�s first constitution in 1776 and was elected governor the  same year (1776-79, 1784-86). As wartime governor, he ably supported  Gen. George Washington; during his second term, he authorized the expe�  dition of George Rogers Clark to invade the Illinois country. In 1788 he  opposed ratification of the U.S. Constitution, which he felt did not suf�  ficiently secure the rights of states and individuals.

After an early association with  the avant-garde at Darmstadt under Leibowitz�s influence, the more tradi�  tional grounding received from Fortner reasserted itself. He moved perma�  nently to Italy in 1953. He is best known for his operas, which include Der  Konig Hirsch (1955), Elegy for Young Lovers (1961), Der junge Lord  (1964), and The Bassarids (1965). He also wrote numerous major sympho�  nies and concertos. His longtime commitment to Marxism expressed itself  in many of his works.

It was discovered  in 1922 and originally used to prevent clotting in blood taken for labo�  ratory tests.</p><p>hepatitis Inflammation of the liver. There are seven known types of viral  hepatitis (A-G). Types A, spread mainly through food contaminated with  feces, and B, transmitted sexually or by injection, cause jaundice and flu�  like symptoms. The hepatitis C virus spreads mostly by shared needles  in intravenous drug use and can cause liver cirrhosis and cancer after a  long latent period. Until recently there was no test to detect it in blood,  and many people were exposed through blood transfusions. Hepatitis D  becomes active only in the presence of type B; it causes severe chronic  liver disease. Type E, like Type A, is transmitted by contaminated food  or water; its symptoms are more severe than Type A�s and can result in  death. The hepatitis F virus (HFV), which was first reported in 1994, is  spread like Type A and E. The hepatitis G virus (HGV), isolated in 1996,  is believed to be responsible for many sexually transmitted and blood-  borne cases of hepatitis. Vaccines exist for types A and B (the second also  prevents type D). Drug treatment for B and C is not always effective. The  other types may not need drug treatment. Chronic active hepatitis causes  spidery and striated skin markings, acne, and abnormal hair growth. It  results in liver tissue death (necrosis) progressing to cirrhosis. Alcoholic  hepatitis, from long-term overconsumption of alcohol, can be reversed  and cirrhosis prevented by early treatment including quitting or sharply  reducing drinking. Other drugs can also cause noninfectious hepatitis. An  autoimmune hepatitis affects mainly young women and is treated with  corticosteroids to relieve symptoms.</p><p>Hepburn, Audrey orig.

In his cosmology, fire forms the basic material  principle of an orderly universe: he called the world order an �ever-living  fire kindling in measures and being extinguished in measures,� and he  extended fire�s manifestations to include the ether in the upper atmosphere.  The persistence of unity despite change is illustrated by his famous analogy  of the river: �Upon those who step into the same rivers, different and ever  different waters flow down.� Plato later took Heracleitus to mean that all  things are in constant flux, regardless of how they appeal - to the senses.</p><p>Heracles \ , her-9-,klez\ Latin Hercules Legendary hero of ancient  Greece and Rome.

He grew up to marry a princess, then killed her in a fit of rage sent by  Hera and was forced to become the servant of Eurystheus, ruler of Greece.  Eurystheus obliged Heracles to perform the famous 12 labors, including  cleansing the Augean stables, fetching the golden apples of the Hes-  perides, and descending into Hades to bring back the three-headed dog  Cerberus. He married Deianeira, who later sent him a shirt smeared with  poison, which she mistakenly believed was a love potion.

April 3,</p><p>1593, Montgomery Castle,</p><p>Wales�d. March 1, 1633, Bemerton, Wiltshire, Eng.) British Metaphysi�  cal poet. He was elected orator of Cambridge University in 1620, a posi�  tion that involved him with the royal court. He was later ordained and  became a rector at a rural parish, to which he devoted himself unstint-  ingly until his death. His poems, published only after his death in The  Temple (1633), concern personal, doctrinal, and ritual matters, and they  are noted for their mastery of metrical form, use of allegory and analogy,  and religious devotion. Some are pattern poems, the lines forming a shape  suggestive of the subject. (See also Metaphysical poetry.)</p><p>Herbert, Victor (August) (b. Feb. 1, 1859, Dublin, Ire.�d. May 26,  1924, New York, N.Y., U.S.) Irish-born U.S. composer. After his widowed  mother married a German doctor, he was raised in Stuttgart, and he stud�  ied at its conservatory. He married the soprano Therese Forrester in 1886,  and they moved to the U.S., she to sing and he to play in the orchestra at  the new Metropolitan Opera. He was soon active as a conductor, cellist,  composer, and teacher. His solid training, orchestrating skill, and melodic  gift found natural expression in more than 40 operettas, including Babes  in Toyland (1903), Mile Modiste (1905), The Red Mill (1906), and  Naughty Marietta (1910).</p><p>Watercolour illustration from the Badi-  anus Manuscript, an Aztec herbal in  Latin by Juan Badianus and Martinus  de la Cruz, 1552; in the Vatican  Library</p><p>COURTESY OF THE VATICAN LIBRARY, VATICAN CITY</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>866 I Herbert &#x25BA; hermeneutics</p><p>Herbert, Zbigniew (b. Oct. 29, 1924, Lwow, Pol.�d. July 28, 1998,  Warsaw) Polish poet and essayist. Herbert started writing at age 17 but  published little before 1956. His poetry expresses an ironic morahsm in  free verse laden with classical and other historical allusions. His most dis�  tinguished collection of poetry, Elegy for an Exit, was published in 1990.  His essays, published in volumes such as Barbarian in the Garden (1962)  and The King of the Ants (1999), are also memorable.</p><p>herbicide Agent, usually chemical, for killing or inhibiting the growth  of unwanted plants (weeds). Modern weed killers are put in two catego�  ries, selective (affecting specific plant species) and nonselective (affect�  ing plants generally). These in turn are classified as foliage-applied and  soil herbicides. Contact herbicides (e.g., sulfuric acid, diquat, paraquat) kill  only the plant organs with which they are in contact. Translocated her�  bicides (e.g., amitrole, picloram, 2,4-D) are effective against roots or other  organs, to which they are transported from aboveground treated surfaces  (soil). See also defoliant.</p><p>herbivore Var-bo-.vorV Animal adapted to subsist solely on plant tissues.  Herbivores range from insects (e.g., aphids) to large mammals (e.g.,  elephants), but the term is most often applied to ungulates. Adaptations for  a herbivorous diet include the four-chambered stomach of ruminants, the  ever-growing incisor teeth of rodents, and the specialized grinding molars  of cattle, sheep, and goats. Certain herbivores eat only one type of food  (e.g., the koala), but most have at least moderate variety in their diet.</p><p>Herblock orig. Herbert Lawrence Block (b. Oct. 13, 1909, Chi�  cago, Ill., U.S.�d. Oct. 7, 2001, Washington, D.C.) U.S. editorial car�  toonist. He first published his cartoons in the Chicago Daily News (1929).  Later he worked for the Newspaper Enterprise Association (1933�43) and  the Washington Post (from 1946). A leading spokesman for liberalism, he  attacked injustices in politics, big business, industry, labour, and econom�  ics throughout his 70-year career. He is best known for his 1950s car�  toons attacking Senator Joseph McCarthy. The winner of three Pulitzer  Prizes (1942, 1954, 1979), Herblock received the Presidential Medal of  Freedom in 1994.</p><p>Herculaneum \,h9r-kyu- , la-ne-9m\ Ancient city, Campania, Italy.  Located at the northwestern foot of Vesuvius, it was destroyed, together  with Pompeii and Stabiae, by the eruption of ad 79. It was buried under a  mass of tufa about 50 to 60 ft (15 to 18 m) deep, which made excavation  difficult but preserved many fragile items. Excavation began in the 18th  century and uncovered numerous artifacts, including paintings and furni�  ture.

Dec. 18, 1803, Weimar, Saxe-Weimar) German critic and  philosopher. Trained in theology and literature, he initially worked as a  teacher and preacher at Riga. As court preacher at Biickeburg, he pro�  duced works, including Plastik (1778) and Essay on the Origin of Lan�  guage (1772), that made him the leading figure of the Sturm und Drang  literary movement. In 1770 he met Johann Wolfgang von Goethe, who  would be his associate for many years and with whom he would help lay  the groundwork for German Romanticism. With Goethe�s help, he received  an appointment at Weimar in 1776; his Sporadic Papers (1785-97) and  the unfinished Outlines of a Philosophy of the History of Man (1784-91),  attempting to show that nature and history obey one system of laws, mark  him as an innovator in the philosophy of history and an early proponent  of the idea that a common culture, rather than political boundaries, defines  a people. His later estrangement from Goethe resulted in a bitter enmity  toward the whole Classical movement in German poetry and philosophy.</p><p>heredity Transmission of physical and mental traits from parents to  offspring through genes. From his studies in the late 19th century, Gre�  gor Mendel derived certain basic concepts of heredity, which eventually  became the foundation for the modem science of genetics. Each member  of the parental generation transmits only half its genes to the offspring,  and different offspring of the same parents receive different combinations  of genes. Many characteristics are polygenic (i.e., influenced by more than  one gene). Many genes exist in numerous variations (alleles) throughout  a population. The polygenic and multiple allelic nature of many traits  gives a vast potential for variability among hereditary characteristics.  While the genotype (an individual�s total hereditary makeup) determines  the broad limits of features an individual may develop, the actual features</p><p>that do develop (the phenotype) are dependent on complex interactions  between genes and their environment. See also variation.</p><p>Hereford Vhsr-fordV Popular breed of beef cattle, the product of gen�  erations of breeding in the English county of Herefordshire. The charac�  teristic colour, red with a white face and white markings, has been fixed  for only a comparatively short time. The outstanding characteristics are  uniformity of colour, early maturity, and ability to thrive under adverse  conditions. Introduced into the U.S. in 1817, it has become the predomi�  nant breed in the range areas of North America from Canada to Mexico.</p><p>Herero \ho-'rer-o\ Group of closely related Bantu-speaking peoples of  southern Africa (central Namibia, eastern Botswana, southern Angola).  The Herero formerly subsisted mainly on the milk and meat of their cattle,  but after European contact in the mid 19th century many came to depend  on horticulture as well. A series of uprisings against German colonial  encroachment (1904-07) led to the extermination of some four-fifths of  their population and the resettlement of survivors in the mostly inhospi�  table sand veld of the western Kalahari. Contemporary estimates number  the Herero at more than 200,000.</p><p>heresy \'her-o-se\ Doctrine rejected as false by religious authorities. In  Christianity, the orthodox theology of the church is thought to be based on  divine revelation, and heretics are viewed as perversely rejecting the guid�  ance of the church. Numerous Christian heresies appeared from the 2nd  century onwards. Early heresies included Arianism, the Monophysite heresy,  Pelagianism, and Donatism. Some heresies, such as Montanism, expressed  faith in a new prophet who added to the body of Christian revelation. Some  types of Gnosticism were heretical branches of Christianity. The major  means of combating heretics in the early church was excommunication. In  the 12th�13th century, the Inquisition was established to combat heresy, and  heretics who refused to recant were often executed. In the 16th century the  Protestant Reformation brought an end to the doctrinal unity of Western  Christendom, and the concept of heresy became less important in the vari�  ous Christian churches, though it continues to exist. The concept of heresy  also exists in Judaism, Buddhism, Hinduism, and Islam.</p><p>herm In Greek religion, a sacred stone object connected with the worship  of Hermes. Herms were used as cult objects, for milestones, and for bound�  ary markers. In time, these stones were replaced by pillars topped with a  likeness of the head of Hermes or by statues of the god. In Roman sculp�  ture the heads of Jupiter or the forest god Silvanus were often substituted.</p><p>Herman, Jerry orig. Gerald Herman (b. July 10, 1933, New York,  N.Y., U.S.) U.S. songwriter.

Known as �The Band  That Plays the Blues,� the group had a hit in 1939 with the riff tune  �Woodchopper�s Ball.� His 1940s bands, the Thundering Herds, evolved  into powerful and colourful ensembles that combined a light rhythm-  section sound with explosive, forward-looking arrangements. He led his  bands almost continuously for more than 50 years, and in them many  notable jazz musicians gained early professional exposure.</p><p>hermaphroditism Mior-'ma-frs-.dl-.ti-zomV Condition of having both  male and female reproductive organs (see reproductive system). It is nor�  mal in most flowering plants and in some invertebrate animals. True  human hermaphrodites are extremely rare. Tissue of the ovary and testes  may occur separately or be combined, external genitals may show traits  of both sexes, and XY and XX sex chromosome pairs are present. If the  condition is detected at birth, the child�s sex can be chosen, usually on  the basis of which sex organs dominate; those of the other sex are removed  surgically. Individuals raised as members of one sex who develop char�  acteristics of the other at puberty may be treated with surgery, and sex  hormones may help them continue to live according to the sexual iden�  tity to which they are accustomed.</p><p>hermeneutics \ 1 hor-m3- , nu-tiks\ Study of the general principles of bib�  lical interpretation.

More recently the word has come to  refer to all �deep� reading of literary and philosophical texts.</p><p>Hermes Vhor-.mezX Greek god, son of Zeus and Maia. The earliest cen�  ter of his cult was probably Arcadia,  where he was worshiped as a god of  fertility. He was also associated with  the protection of cattle and sheep. In  Homer�s Odyssey he appears as the  messenger of the gods and the con�  ductor of the dead to Hades. As a  messenger he also became the god of  roads and doorways and the protec�  tor of travelers. He was also the god  of dreams. His Roman counterpart  was Mercury.</p><p>Hermetic writings Occult texts  on philosophical or theological sub�  jects ascribed to Hermes Trismegis-  tos (�Hermes the Thrice-Greatest�),  identical to the Egyptian god Thoth,  who was credited with inventing  writing. The collection, written in  Greek and Latin, was probably put  together in the lst-3rd century ad.</p><p>Written in the form of dialogues, it  synthesizes Near Eastern religion, Platonism, Stoicism, and other philoso�  phies. It also reflects ideas and beliefs widely held in the early Roman  empire on astrology, alchemy, and magic.

Works produced within the movement are characterized by unor�  thodox structure, illogical sequences, and highly subjective language. Its  formalistic devices were partly derived from Futurism, but the cryptic brev�  ity, obscurity, and involution of the Hermetics was forced on them by fas�  cist censors. Giuseppe Ungaretti, Salvatore Quasimodo, and Eugenio  Montale were the principal exponents of the movement, which was named  for Hermes Trismegistos, a reputed author of occult symbolic works (see  Hermetic writings).</p><p>hermit or eremite Individual who shuns society to live in solitude,  often for religious reasons. The first Christian hermits appeared in Egypt in  the 3rd century ad, escaping persecution by withdrawing to the desert and  leading a life of prayer and penance. The first hermit was probably Paul of  Thebes c. ad 250. Other famous hermits included St. Anthony of Egypt, who  established an early form of Christian monasticism in the 4th century, and  the pillar hermit Simeon Stylites. The communal life of monasteries even�  tually tempered the austerities of the hermit�s life. In Western Christianity  the eremitic life died out, but it has persisted in Eastern Christianity.</p><p>hermit crab Any crab (families Paguridae and Coenobitidae) that uses  empty shells or other hollow objects  as a shelter for partial containment  and protection of the body. They are  found worldwide in sandy- or  muddy-bottomed waters and occa�  sionally on land and in trees. They  have two pairs of antennae and four  pairs of legs; the first pair of legs is  modified to form pincers, shaped to  cover the shell entrance when the  animal is inside. As the crab grows,  it periodically leaves its shell and  finds a larger one to occupy. The red�  dish brown large hermit crab ( Pagu-  rus pollicaris ; 4-5 in., or 10-12 cm,  long) and the small hermit crab ( P. ! longicarpus) are found in North Ameri�  can Atlantic coastal waters.</p><p>Hermitage (museum) \er-mi-'tazh,\ English Vhor-ms-tijN Largest  museum in Russia and one of the most important in the world. Located  in St. Petersburg, it derives its name from the �Hermitage� pavilion  adjoining the Winter Palace, built in 1764-67 for Catherine II (the Great)  as a private gallery for her treasured collections. On her death in 1796,  the imperial collections were estimated to total 4,000 pictures. After the  Winter Palace was destroyed by fire in 1837, the Hermitage was recon�  structed and opened to the public by Nicholas I in 1852. After the Bol�  shevik Revolution, the collections were transferred to public ownership.  The museum is now housed in five interconnected buildings, including  the Winter Palace and the Small, Old, and New Hermitages. Along with  thousands of art objects from Central Asia, India, China, Egypt, the pre-  Columbian Americas, Greece, and Rome, the Hermitage houses outstand�  ing collections of Western painting.

Located west of  Damascus and rising to 9,232 ft (2,814 m), it is the highest point on the  eastern coast of the Mediterranean Sea and is sometimes considered the  southernmost extension of the Anti-Lebanon Mountains. A sacred land�  mark in Hittite, Palestinian, and Roman times, it represented the north�  western limit of Israelite conquest under Moses and Joshua.

U.S. playwright. He worked as  a traveling actor before achieving success with his first play, Hearts of  Oak (1879; written with David Belasco). Margaret Fleming (1890) is con�  sidered his major achievement, though Shore Acres (1892) was his most  popular play. He helped bridge the gap between 19th-century melodrama  and the 20th-century drama of ideas.</p><p>hernia Protrusion of any organ or tissue from its normal cavity. The  term usually refers to an abdominal hernia, which may be a congenital  disorder or acquired after birth. Tissue may protrude through the abdomi�  nal muscle at the groin (inguinal), upper thigh (femoral), or navel (umbili�  cal); its circulation can become cut off, leading to inflammation, infection,  and gangrene. If the tissue cannot be pushed back into place and kept  there by a truss, surgery may be necessary. Other common hernias are  hiatal hernia (protrusion of part or all of the stomach above the diaphragm)  and herniated disk (protrusion of tissue from a disk in the vertebral col�  umn through its outer layer).</p><p>hero Mythological or legendary figure, often of divine descent, who is  endowed with great strength or ability, like the heroes celebrated in early  epics such as Cilgamesh, The Iliad, Beowulf, or the Chanson de Roland.  Usually illustrious warriors or adventurers, heroes are often represented  as fulfilling a quest (e.g., Aeneas, in Virgil�s Aeneid, founding the Roman  state, or Beowulf ridding his people of the monstrous Grendel and his  mother). Heroes often possess special qualities such as unusual beauty,  precocity, and skills in many crafts. Often inclined to boasting and fool�  hardiness, they defy pain and death to live fully, creating a moment�s glory  that survives in the memory of their descendants.</p><p>Hero and Leander \le-'an-dar\ Lovers celebrated in Greek legend.  Hero, a virgin priestess of Aphrodite, was seen by Leander of Abydos dur�  ing a festival, and the two fell in love. He swam the Hellespont nightly  to be with her, guided by a light from her tower. One stormy night the  lamp was extinguished, and Leander drowned. When Hero saw his body  on the shore, she threw herself from the tower into the sea.

March/April, 4 bc,  Jericho, Judaea) Roman-appointed king of Judaea (37-4 bc). A practicing  Jew, he was of Arab origin. He was critical to imperial control of Judaea,  despite his earlier support of Mark Antony, and the Roman emperor  increased his territory. Judaea prospered under his early reign, during  which he increased trade and built fortresses, aqueducts, and theatres, but  he could not give full rein to his desire to build and thrive because he  feared the Pharisees, Judaism�s controlling faction, who viewed him as a  foreigner. He lost favour through increasing cruelty, manifest in the mur�  der of his wife, her sons, and other relatives. His grip on his kingdom  weakened as he became increasingly mentally unstable and physically  debilitated. He killed his eldest son, and he slew the infants of Bethlehem  (see Jesus). He died shortly after a bungled suicide attempt.</p><p>Herod Agrippa I \9-'grip-3\ orig. Marcus Julius Agrippa (b. c.</p><p>10 bc� d. ad 44) King of Judaea (ad 41-44). Grandson of Herod the Great  and nephew of Herod Antipas, he became friends in Rome with the  emperor Tiberius and Caligula. Caligula made him king of his uncle�s realm  in northeastern Palestine and of Galilee, and after Caligula�s death  Herod�s support of Claudius earned him the kingdom of Judaea, where he  won the support of the Jews and repressed Jewish Christians. He built  public buildings in Beirut and hosted games at Caesarea to honour Clau�  dius. He died suddenly during the games.</p><p>Herod Antipas \'an-ti-pos\ (b. 21 bc � d. ad 39) Son of Herod the Great  and tetrarch of Galilee (4 bc-ad 39) throughout Jesus� ministry. He was  responsible for the death of John the Baptist (demanded by his wife,  Herodias, and stepdaughter, Salome) but later refused to cooperate when  Pontius Pilate pressed him to conduct the trial of Jesus. He was caught up  in the intrigue between the Syrians and Nabataeans. After denouncing  Herod Agrippa I, he was banished by Caligula to Gaul. He built the city of  Tiberias.</p><p>Herodotus Mio-'ra-do-tosX (b. 484?, Helicamassus, Asia Minor�d. 430/  420 bc) Greek historian. He resided in Athens and then in Thurii in south�  ern Italy. His travels covered a large part of the Persian empire. He is the  author of the first great narrative history produced in the ancient world,  the History of the Persian Wars. It is a unified artistic masterpiece, with  many illuminating digressions and anecdotes skillfully worked into the  narrative. Despite many inaccuracies, it remains the leading source of  original information about Greece between 550 and 479 bc, as well as  that of much of western Asia and Egypt.</p><p>heroin Heterocyclic compound, a highly addictive alkaloid derivative of  morphine (chemically, it is diacetylmorphine) that makes up a large por�  tion of illicit narcotics traffic. Easily made from morphine, it was devel�  oped and first used as an analgesic, but its undesirable effects outweighed  its value, and it is illegal in most countries. Injection brings an ecstatic,  warm, glowing sensation, followed by relaxation and contentment. Within  half a day withdrawal symptoms set in, with a craving for more. Devel�  opment of tolerance, requiring ever greater amounts for the same effects,  leads to drug addiction. Illegal street heroin is usually only 2-5% pure;  unwitting injection of relatively pure heroin is a major cause of overdose,  resulting in depressed respiration, coma, and death.</p><p>heron Any of about 60 species of long-legged wading birds in the same  family (Ardeidae) as egrets and bitterns. They are found worldwide but  are most common in the tropics. They wade in the shallow waters of pools,  marshes, and swamps, catching frogs, fishes, and other aquatic animals.  They nest on rough stick platforms in bushes or trees near water. Herons  commonly stand with their neck bent in an southern shape and fly with  their legs trailing and their head held back. They have broad wings and a  long, straight, shaip-pointed bill. They are subdivided into typical herons  (including the 50-in., or 130-cm, great blue heron of North America),  night herons, and tiger herons.</p><p>Heron of Alexandria or Hero of Alexandria (fl. c. ad 62, Alex�  andria, Egypt) Greek mathematician and inventor. He is remembered for  his formula for the area of a triangle and for inventing the aeolipile, the  first steam engine, which, in his design, was a forerunner of the jet engine.  Of his many treatises, one contains a method for approximating the square  root of a number. His writings on mechanics include discussions of the  five simple machines, mechanical problems of daily life, and the construc�  tion of many kinds of engines.</p><p>Heron's Vhir-,anz\ formula Formula for finding the area of a triangle  in terms of the lengths of its sides.

He per�  formed public dissections on human corpses; studied the cavities of the  brain, which he regarded as the centre of the nervous system; traced the  sinuses of the dura mater to their junction (the torcular Herophili); and  classified nerve trunks as motor and sensory, distinguishing them from  tendons and blood vessels. He described the eye, liver, salivary glands,  pancreas, genitals, duodenum, and prostate gland (naming the last two)  and was the first to measure the pulse. A student of Hippocrates� doctrine,  he emphasized the curative powers of drugs, diet, and gymnastics. He  wrote at least nine works, including a commentary on Hippocrates and a  book for midwives, all lost in the destruction of the library of Alexandria.</p><p>herpes Vhor-.pezV simplex Infection caused by herpes simplex virus.  Type I typically produces a cluster of small blisters (cold sores, or fever  blisters), usually on the lips or face; it can also infect the eyes. Type II,  transmitted mostly through sexual contact, causes genital blisters, which  rupture, becoming very painful. Oral sex can give either type the chance  to infect the usual site of the other. In both types, the virus remains after  symptoms end and can reactivate, causing blisters to reappear. Babies  born to mothers with active herpes can become infected during birth; this  can be prevented by cesarean section. There is no cure, but drugs can  reduce severity and risk of transmission.</p><p>herpes zoster See shingles</p><p>Herrera (h)o-'rer-3\, Francisco, the Elder (b. c. 1576, Sevilla,  Spain�d. 1656, Madrid) Spanish painter.

Around 1650 he moved to Madrid. His last documented work, a  painting of St. Joseph (1648) influenced by Anthony Van Dyck, features  elongated forms and elaborate draperies.

He grew up  in California and �passed� as white, along with his Creole parents. He  started cartooning after a fall from a scaffold prevented him from work�  ing as a house painter. His first comic strip. Lariat Pete , appeared in 1903  in the San Francisco Chronicle ; it was followed by several others. His  best-known strip, Krazy Kat, appeared in 1910 and settled in for a run of  more than 30 years in the William Randolph Hearst newspapers. Krazy  Kat�s fantasy, drawing, and dialogue were of such high quality that some  people consider it the finest comic strip ever published.</p><p>herring Either the Atlantic or the Pacific subspecies of Clupea haren-  gus (once considered two separate species), slab-sided, northern fishes  that are small-headed and streamlined, with silvery iridescent sides and a  deep-blue, metallic-hued back. The name also refers to some other mem�  bers of the family Clupeidae. Adults range in length from 8 to 15 in.  (20-38 cm). One of the most abundant species of fish, herring travel in  enormous schools. They eat planktonic crustaceans and fish larvae. In  Europe they are processed and sold as kippered herring; in eastern Canada  and the northeastern U.S., most of the herring used are young fishes  canned as sardines. Herring taken in the Pacific are used mainly to make  fish oil and meal.</p><p>herring gull Most common of the Atlantic gulls in the Northern Hemi�  sphere. The herring gull (Larus argentatus) has a gray mantle, flesh-  coloured legs and feet, and black-and-white-spotted wing tips. Herring  gulls are primarily scavengers; their populations are generally increasing  because of expanding food supplies, chiefly garbage and sewage in or near  coastal waters.</p><p>Herriot V.er-e-'oX, Edouard (b. July 5,1872, Troyes, France�d. March  26, 1957, Lyon) French politician and writer. He became mayor of Lyon  in 1905 and kept the post for most of his life. Elected as a member of the  Radical Party to the Chamber of Deputies (1919), he led the opposition  to the Bloc National as head of the Cartel des Gauches (1924). As prime  minister (1924-25) he forced the resignation of the president, Alexandre  Millerand and led France to accept the Dawes Plan and to recognize the  Soviet Union. In 1926 he was prime minister for three days and held the  position again in 1932. He abstained from voting when the National  Assembly gave full powers to Philippe Petain at Vichy in 1940 and then was  arrested and deported to Germany (1942-45). He returned to France and  served as president of the National Assembly from 1947 to 1954. In his  long career he served in nine different cabinets.</p><p>Herriot \'her-e-ot\, James orig. James Alfred Wight (b. Oct. 3,  1916, Glasgow, Scot.�d. Feb. 23, 1995, Thirlby, nearThirsk, Yorkshire,  Eng.) British veterinarian and writer. Wight joined the practice of two  veterinarian brothers working in the Yorkshire Dales and at age 50 was  persuaded by his wife to write down his collection of anecdotes. His  humorous, fictionalized reminiscences were published under the name  James Herriot in If Only They Could Talk (1970) and It Shouldn�t Hap�  pen to a Vet (1972), which were issued in the U.S. as All Creatures Great  and Small (1972). The instant best-seller inaugurated a series of highly  popular books, which was adapted for two films and a long-running tele�  vision series.</p><p>Herrmann, Bernard (b. June 29, 1911, New York, N.Y., U.S.�d.  Dec. 24, 1975, Los Angeles, Calif.) U.S. composer. He studied at New  York University and Juilliard and was one of a group of young compos�  ers associated with Charles Ives in the 1930s. Active in radio from 1930,  he worked with Orson Welles, which led to a career in film. He wrote  scores for Welles�s Citizen Kane (1941) and The Magnificent Ambersons  (1942); other films include All That Money Can Buy (1941, Academy  Award). He wrote the scores for eight of Alfred Hitchcock�s films, includ�  ing Vertigo (1958), North by Northwest (1959), and Psycho (1960).</p><p>Herschel Vhsr-shalX family Family of British astronomers. The  German-bom William Herschel (1738-1822) immigrated to England in  1757 and initially supported himself through music. In order to study dis�  tant celestial objects, he ground his own mirrors, producing the best tele�  scopes of the day. His discovery of Uranus catapulted him to fame at age  43. He hypothesized that nebulae (those objects now known to be galax�</p><p>ies) are composed of stars and developed a theory of stellar evolution. He  also discovered infrared radiation. He was knighted in 1816. His sister,  Caroline Lucretia Herschel (1750-1848), contributed to her brother�s  researches, carrying out many of the necessary calculations. She also  detected by telescope three nebulae and eight comets. In 1787 the king  gave her an annual pension in recognition of her work. She continued to  work for decades after William�s death. William�s son John (1792-1871)  studied mathematics at the University of Cambridge and from 1816  assisted his father. He later undertook a journey to the Southern Hemi�  sphere to survey its skies; he returned in 1838, having recorded the loca�  tions of 68,948 stars. Also an accomplished chemist, he invented  (independently of William Henry Fox Talbot) the process of photography on  sensitized paper. He was knighted in 1831. His sons Alexander Stewart  (1836-1907) and John (1837-1921) also became astronomers.</p><p>Hersey, John (Richard) (b. June 17, 1914, Tianjin, China�d. March  24, 1993, Key West, Fla., U.S.) Chinese-born U.S. novelist and journal�  ist. Born to missionaries, he worked as a correspondent in East Asia, Italy,  and the Soviet Union in the years 1937-46. His novel A Bell for Adano  (1944, Pulitzer Prize) depicts the Allied occupation of a Sicilian town.  Hiroshima (1946), about the experiences of atomic-blast survivors, and  The Wall (1950), about the Warsaw ghetto uprisings, combine fact and  fiction. His later novels encompassed a wide variety of subjects from con�  temporary issues to moral parables set in the future.</p><p>Hersh, Seymour (Myron) (b. April 8, 1937, Chicago, Ill., U.S.) U.S.  journalist. He graduated from the University of Chicago in 1954. He  began his journalistic career in 1959 as a police reporter, and he later  worked for UPI and The New York Times and as a national correspondent  for The Atlantic Monthly. His report on the My Lai incident won him a 1970  Pulitzer Prize; he also wrote about domestic spying by the CIA and pro�  duced many other investigative reports. His The Dark Side of Camelot  (1997) was a controversial, negative look at John F. Kennedy; Against All  Enemies (1998) discussed the ailments suffered by Persian Gulf War vet�  erans.</p><p>Hershey, A(lfred) D(ay) (b. Dec. 4, 1908, Owosso, Mich., U.S.�d.  May 22, 1997, Syosset, N.Y.) U.S. biologist. He worked principally at the  Carnegie Institution in Washington, D.C. He and Salvador Luria indepen�  dently demonstrated the occurrence of spontaneous mutation in both bac�  teriophages and hosts. Later, Hershey and Max DelbrOck independently  discovered the occurrence of genetic recombination in phages. Delbriick  incorrectly interpreted his results, but Hershey proved that the results he  had obtained were recombinations by showing that the genetic processes  in question correspond with the crossing-over of parts of similar chro�  mosomes observed in cells of higher organisms. He showed that phage  DNA is the main component entering the host cell during infection and  that DNA, rather than protein, is the phage�s genetic material. In 1969 he  shared a Nobel Prize with Luria and Delbriick.</p><p>Hertford \'har-ford\ Town (pop., 1995 est.: 23,000), East Hertfordshire  district, administrative and historic county of Hertfordshire, southeastern  England. Located on the northern periphery of London, Hertford was first  recorded as the scene of a general synod led by Theodore of Tarsus in ad  672. The oldest buildings extant are 15th-century timber-framed houses.  The town has light engineering industries and many agricultural connec�  tions. It is the county�s administrative centre.</p><p>Hertfordshire Vhar-ford-.shirX Administrative (pop. 2001: 1,033,977)  and historic county, southern England. It adjoins London on that city�s  northern side; its county seat is Hertford. It includes the two early �gar�  den cities��Letchworth (1903) and Welwyn Garden City (1920)�and  four of the eight new towns planned around London since World War II  (1939-45). With an array of direct road and rail links to London, it houses  light industries, offices, film studios, and thousands of exurbanites.</p><p>Hertz \'herts,\ English VhortsV Heinrich (Rudolf) (b. Feb. 22, 1857,  Hamburg, Ger.�d. Jan. 1, 1894, Bonn) German physicist. While a pro�  fessor at Karlsruhe Polytechnic (1885-89), he produced electromagnetic  waves in the laboratory and measured their length and velocity. He  showed that the nature of their vibration and their susceptibility to reflec�  tion and refraction were the same as those of light waves, and he proved  that light and heat are electromagnetic radiations. He was the first to  broadcast and receive radio waves. In 1889 he was appointed professor  at the University of Bonn, where he continued his research on the dis�  charge of electricity in rarefied gases. The hertz (Hz), a unit of frequency  in cycles per second, is named for him.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>870 I Hertzog &#x25BA; Hesse</p><p>Hertzog Vhert-.sokV, J(ames) B(arry) M(unnik) (b. April 3, 1866,  near Wellington, Cape Colony�d. Nov. 21, 1942, Pretoria, S.Af.) Prime  minister of the Union of South Africa (1924-39). His political principles  were �South Africa First� (i.e., ahead of the British Empire) and the �Two  Streams Policy,� under which British and Afrikaner would be free from  domination by each other. He served in the cabinet of Louis Botha (1910�  12), but he broke with Botha because of his nationalist sympathies and  formed the National Party. As prime minister, Hertzog gave South Africa  its flag, made Afrikaans an official language, promoted apartheid, and  affirmed the equality of British and Afrikaner rights. In 1933 he was forced  to accept a coalition with Jan Smuts, and in 1939 he resigned over the  issue of neutrality in World War II.</p><p>Hertzsprung-Russell Vhert-spriirj-'ro-soH diagram or H-R dia�  gram Graph in which the absolute magnitudes of stars are plotted against  their colours (a measure of their temperatures). Of great importance to  theories of stellar evolution, it evolved from charts begun independently  in 1911 by the Danish astronomer Ejnar Hertzsprung (1873-1967) and  the U.S. astronomer Henry Norris Russell (1877-1957). On the diagram,  stars are ranked from bottom to top in order of increasing brightness and  from right to left by increasing temperature. Stars tend to cluster in cer�  tain parts of the diagram, especially along a diagonal line, called the main  sequence, which is the locus of hydrogen-burning stars of different  masses.</p><p>Hervey Bay Inlet and city (pop., 2001: 41,890), southeastern Queens�  land, Australia. Named in 1770 by Capt. James Cook and surveyed in 1804,  the bay measures 55 by 40 mi (89 by 64 km). Hervey Bay city comprises  a complex of bayside resorts, which also serve a district of sugarcane and  pineapple plantations.</p><p>Herzegovina See Bosnia and Herzegovina</p><p>Herzen \'hert-son\, Aleksandr (Ivanovich) (b. April 6, 1812, Mos�  cow, Russia�d. Jan. 21, 1870, Paris, France) Russian writer and politi�  cal activist. As a student at the University of Moscow, he joined a socialist  group, for which he was exiled to work in the provincial bureaucracy  (1834�42). Returning to Moscow, he joined the Westemizers but then  turned to anarchist socialism. After inheriting a considerable fortune, he  left Russia. In Paris he proclaimed Western institutions �dead� and devel�  oped the theory of a unique Russian path to socialism known as peasant  populism. He moved to London in 1852 and founded the Free Russian  Press, as well as the influential newspaper Kolokol (�The Bell�) in 1857;  smuggled into Russia, the paper was read by both reformers and revolu�  tionaries. When the Emancipation Act was enacted in 1861, he denounced  it as a betrayal of the peasants. He then turned his energies to writing My  Past and Thoughts (1861-67), considered one of the greatest works of  Russian prose.</p><p>Herzl Vhert-s 3 l\, Theodor (b. May 2, 1860, Budapest, Hungary�d.  July 3, 1904, Edlach, Austria) Hungarian Zionist leader. Growing up Jew�  ish in Hungary, he believed that assimilation was the best strategy to deal  with the anti-Semitism he encountered. He became a Zionist while cov�  ering the Alfred Dreyfus affair as a journalist in Paris. In 1897 he orga�  nized a world congress of Zionism, which was attended by about 200  delegates, and he became the first president of the World Zionist Orga�  nization, established by the congress. Herzl�s indefatigable organizing,  propagandizing, and diplomacy had much to do with making Zionism a  political movement of worldwide significance. Though he died more than  40 years before the establishment of the state of Israel, his remains were  moved to Jerusalem in 1949 and entombed on a hill now known as Mount  Herzl.</p><p>Herzog Vhert-sok\, Werner orig. Werner H. Stipetic (b. Sept. 5,  1942, Munich, Ger.) German filmmaker. He won two awards for his first  feature film, Signs of Life (1967), which introduced the theme of a descent  into madness that was to reappear in his later films, most powerfully in  Aguirre, the Wrath of God (1972), Nosferatu (1979), and Fitzcarraldo  (1982). He documented his tumultuous friendship with actor Klaus Kin�  ski in the film My Best Fiend (1999). His surreal and exotic films were  among the best of the highly praised postwar West German cinema.</p><p>Heschel Vhe-shoL, Abraham Joshua (b. 1907, Warsaw, Pol., Rus�  sian Empire�d. Dec. 23, 1972, New York, N.Y., U.S.) Polish-born U.S.  Jewish philosopher and theologian. He studied at the University of Ber�  lin and taught Jewish studies in Germany until he was deported by the  Nazis in 1938. After coming to the U.S., he taught at Hebrew Union Col�</p><p>lege and later at Jewish Theological Seminary. His goal was to devise a  modern philosophy of religion based on ancient and medieval Judaic tra�  ditions, and he emphasized Judaism�s prophetic and mystical aspects.  Emphasizing social action as an expression of pious ethical concerns, he  worked for black civil rights and against the Vietnam War. His writings  include Man Is Not Alone (1951) and God in Search of Man (1956).</p><p>Heshen or Ho-shen (b. 1750, China�d. Feb. 22, 1799, Beijing) Infa�  mous Chinese courtier who abused his influence with the Qianlong  emperor to assume high ministerial positions and control revenue disburse�  ments and personnel recruiting. His embezzlement of funds intended for  suppressing the White Lotus rebellion prolonged the fighting and drove  the imperial troops to looting, consequently undermining the authority of  the Qing dynasty. He was arrested by the Qianlong emperor�s successor  and forced to commit suicide.</p><p>Hesiod Vhe-se-od, 'he-se-od\ (fl. c. 700 bc) Greek poet. One of the ear�  liest Greek poets, he is often called the father of Greek didactic poetry. A  native of Boeotia, in central Greece, he may have been a professional  reciter of poetry. Two complete epics have survived: the Theogony, relat�  ing stories of the gods, and the Works and Days, describing peasant life  and expressing his views on the proper conduct of men. His works reveal  his essentially serious outlook on life and portray a less glamorous world  than Homer�s. His poems won renown during his lifetime, and the power  of his name was such that epics by others were later attributed to him.</p><p>Hess, (Walter Richard) Rudolf (b. April 26, 1894, Alexandria,  Egypt�d. Aug. 17, 1987, West Berlin, W.Ger.) German Nazi leader. He  joined the fledgling Nazi Party in 1920 and soon became Adolf Hitler�s  friend. After participating in the Beer Hall Putsch (1923), he escaped but  returned voluntarily to prison, where he took down dictation for Hitler�s  Mein Kampf He became Hitler�s private secretary and, in 1933, deputy  party leader. In the early days of World War II his power waned. In 1941  he created an international sensation when he secretly landed by para�  chute in Scotland on an abortive mission to negotiate peace between Brit�  ain and Germany. The British government held him as a prisoner of war,  and his peace initiative was rejected by Hitler. He was given a life sen�  tence at the NOrnberg trials, and from 1966 he was the sole inmate at  Spandau prison.</p><p>Hess, Victor Francis (b. June 24, 1883, Waldstein, Styria, Austria�d.  Dec. 17, 1964, Mount Vernon, N.Y., U.S.) Austrian-born U.S. physicist.  He received his doctorate from the University of Vienna in 1906. His  research dealt chiefly with radioactivity and atmospheric electricity. His  experiments proved what had long been suspected: an extremely pen�  etrating radiation of extraterrestrial origin permeates the atmosphere (see  cosmic ray). Further investigation of this radiation, named cosmic rays in  1925, led Carl D. Anderson (1905-91) to discover the positron and opened  up new fields of research in modern physics. For this work, Hess and  Anderson shared a Nobel Prize in 1936.</p><p>Hess, Walter Rudolf (b. March 17,1881, Frauenfeld, Switz.�d. Aug.  12, 1973, Locarno) Swiss physiologist. He worked at the University of  Zurich (1917-51). His interests centred on the nerves that control auto�  matic functions such as digestion and excretion and that also trigger the  activities of a group of organs that respond to complex stimuli, such as  stress. Using fine electrodes to stimulate or destroy specific areas of the  brain in cats and dogs, Hess mapped the control centres for each func�  tion to such a degree that he could bring about the physical behaviour  pattern of a cat confronted by a dog simply by stimulating the proper  points on the cat�s hypothalamus. He shared a 1949 Nobel Prize with  Antonio Egas Moniz.</p><p>Hesse \'hes\ German Hessen State (pop., 2002 est.: 6,077,826), west-  central Germany. It occupies an area of 8,152 sq mi (21,114 sq km). Its  capital is Wiesbaden. It was formed in 1945 through the amalgamation of  former Prussian provincial units. The Hessians are thought to be  descended from the Frankish tribe of the Chatti, who were Christianized  by St. Boniface in the early 8th century ad. Hesse was twice partitioned  in the 15th century, but Philip of Hesse reunited the territory. The area has  small farms, and the state�s industries are centred in the Rhine-Main area.  The ruins of many castles and old churches and palaces are on the banks  of the Weser River.</p><p>Hesse Vhes-oX, Eva (b. Jan. 11, 1936, Hamburg, Ger.�d.

She attended</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Hesse &#x25BA; Heydrich I 871</p><p>the Pratt Institute, Cooper Union, and Yale University. In 1964 she mar�  ried and moved briefly to Germany and began making sculpture, devel�  oping a style featuring sensuous shapes and unconventional materials  (including rubber tubing, synthetic resins, cord, cloth, and wire). In the  1960s she exhibited throughout the U.S. and achieved critical acclaim;  her work was sometimes asssociated with Minimalism. In 1969 she under�  went the first of three unsuccessful operations for a brain tumour. Her  influence since her death has been widespread.</p><p>Hesse Vhes-oX, Hermann (b. July 2, 1877, Calw, Ger.�d. Aug. 9,  1962, Montagnola, Switz.) German  novelist and poet. He left the semi�  nary because of his inability to adapt  to the life there. His first novel was  Peter Camenzind (1904); it was fol�  lowed by Beneath the Wheel (1906),</p><p>Gertrud (1910), and Rosshalde  (1914). An opponent of militarism,  he settled permanently in Switzer�  land at the outbreak of World War I  (1914-18). His later works deal with  the individual�s search for spiritual  fulfillment, often through mysticism.</p><p>Demian (1919), influenced by his  experience with psychoanalysis,  made him famous. Siddhartha  (1922), about the early life of Bud�  dha, reflects his interest in Eastern  spiritualism. Steppenwolf (1927),  which examines the conflict between  bourgeois acceptance and spiritual  self-realization, was highly influen�  tial in its time and brought him cult status among the young of more than  one generation. Narcissus and Goldmund (1930) and The Glass Bead  Game (1943; also published as Magister Ludi) concern duality and the  conflict between the contemplative and the active life. He won the Nobel  Prize for Literature in 1946. His mysticism and his interest in self-  realization kept him popular long after his death.</p><p>Hestia Greek goddess of the hearth and 1 of the 12 chief deities of Mount  Olympus. She was the daughter of Rhea and Cronus. When Apollo and  Poseidon became suitors for her hand, she swore to remain a maiden for�  ever, whereupon Zeus gave her the honour of presiding over all sacrifices.  Though mainly a goddess of the family hearth and domestic life, she was  sometimes also worshiped at the civic hearth in public buildings.</p><p>Heston, Charlton orig. John Charlton Carter (b. Oct. 4, 1924,  Evanston, Ill., U.S.) U.S. actor. He made his Broadway debut in Antony  and Cleopatra (1947) and his film debut in Dark City (1950). He became  a star in The Greatest Show on Earth (1952) and was a muscular and  dignified stalwart in epic films such as The Ten Commandments (1956),  Ben-Hur (1959, Academy Award), and The Agony and the Ecstasy { 1965).  He also starred in Touch of Evil (1958), Planet of the Apes (1968), and  The Three Musketeers (1973) and directed and acted in Antony and Cleo�  patra (1972) and Mother Lode (1982). He was president of the Screen  Actors Guild (1966-71) and the National Rifle Association (1998-2003).</p><p>Hesychius \h3-'si-ke-os\ of Alexandria (fl. 5th century ad) Greek  scholar and linguist. He compiled the Alphabetical Collection of All  Words, the most complete Greek lexicon known from antiquity. Though  preserved only in a 15th-century abridgment by a Venetian editor, it is  valued as a basic authority for the dialects and vocabularies of ancient  inscriptions and poetry as well as the sacred writings of the Greek Church  Fathers (see patristic literature).</p><p>heterocyclic \ l he-t3-ro-'sI-klik\ compound Any of a class of organic  compounds whose molecules contain one or more rings of atoms with at  least one atom (the heteroatom) being an element other than carbon, most  frequently oxygen, nitrogen, or sulfur. As in regular cyclic hydrocarbons,  such heterocyclic rings may include single, double, or triple bonds or be  aromatic (see covalent bond; aromatic compound), and the compound may  contain one or more single rings or have fused rings (in which adjoining  rings share two carbon atoms). Compounds having five-membered het�  erocyclic rings include chlorophyll, hemoglobin, indigo, tryptophan, and  certain polymers. Those with six-membered heterocyclic rings include  pyridine, pyridoxine (vitamin B 6 ; see vitamin B complex), vitamin E, quinine,</p><p>and the pyran nucleus, which is found in sugars and the anthocyanin pig�  ments. Nicotine and morphine have both five- and six-membered hetero�  cyclic rings; some antibiotics (e.g., penicillin) have two different  heteroatoms in their rings. Other important heterocyclic compounds are  pyrimidines, which occur in barbiturates, and purines, which occur in caffeine  and related compounds; pyrimidine and purine are the parent compounds  of the NUCLEIC ACIDS.</p><p>heterosis \,he-t9-'ro-s3s\ or hybrid vigor Increase in such charac�  teristics as size, growth rate, fertility, and yield of a hybrid organism over  those of its parents. Plant and animal breeders exploit heterosis by mat�  ing two different purebred lines that have desirable traits. The first-  generation offspring generally show, in greater measure, the desired  characteristics of both parents. Since this vigour may decrease if the  hybrids are actually mated together, the parental lines must be maintained  and crossed for each new crop or group desired.</p><p>heterozygote See homozygote and heterozygote</p><p>Heuss Vh6is\, Theodor (b.

A member of the German Democratic Party during the Weimar  Republic, he served in the Reichstag (1924-28, 1930-33). After Adolf Hit�  ler came to power, Heuss�s books on political science were burned as  �un-German.� After World War II (1939�45), he helped found the Free  Democratic Party and served (1948-49) on the parliamentary council that  wrote the West German constitution. He served as president of the new  state from 1949 until his retirement in 1959.</p><p>Hewish, Antony (b. May 11, 1924, Fowey, Cornwall, Eng.) British  astrophysicist. In 1967 Hewish determined that the regularly patterned  radio signals (pulses) that Jocelyn Bell Burnell had detected were not  caused by earthly interference or, as some speculated, by intelligent life-  forms trying to communicate with distant planets but were energy emis�  sions from certain stars. For this work in identifying pulsars as a new class  of stars, he shared a 1974 Nobel Prize with Martin Ryle.</p><p>Hewitt, Abram S(tevens) (b. July 31, 1822, Haverstraw, N.Y.,  U.S.�d. Jan. 18, 1903, Ringwood, N.J.) U.S. industrialist and politician.  A graduate of Columbia College (now part of Columbia University) in  1842, he formed an iron-making business with Edward and Peter Cooper  in New York City in 1845; he later helped establish the Cooper Union  school (1859). During the American Civil War, he produced gun-barrel iron  for the government without taking a profit. In 1870 he produced the first  commercial-grade steel in the U.S. In 1871 he helped Samuel Tilden oust  the �Tweed Ring� (see William Marcy Tweed) from control of the Tammany  Hall Democratic organization and the municipal government of New York  City. He later served in the U.S. House of Representatives (1875-79,  1881-86). As mayor of New York (1887-88), he initiated major reforms  that broke Tammany Hall�s influence.</p><p>Hewlett-Packard Co. U.S. manufacturer of computers, computer  printers, and measuring instruments. Founded in 1938 in Palo Alto, Calif.,  by William Hewlett (1913-2001) and David Packard (1912-96), the com�  pany grew along with the electronics sector of the U.S. defense industry  after World War II (1939-45). In 1966 it developed its first computer, and  in 1968 one of the earliest desktop electronic calculators. Hewlett-Packard  entered the personal-computer market in 1980, and its HP Laser Jet printer  dominated the market for computer printers in the 1980s. By the 1990s  the company was a leading maker of minicomputers used by businesses  and institutions and a leader in the field of laser and inkjet printers. In  2002 the company bought rival Compaq Computer for $25 billion.</p><p>hexachord Greek "six strings" In music, a group of six tones in a  specified pattern, specifically the interval pattern tone-tone-semitone-tone-  tone (as in G-A-B-C-D-E). The hexachord was apparently conceived in  the 11th century when theorist Guido d�Arezzo noticed that the scales of  the church modes could be seen to overlap in their interval patterns. His  system of solmization gave each hexachord the same syllables (ut-re-mi-  fa-sol-la), and by means of overlapping hexachords the theorist could  represent the complete �gamut� of pitches. Though counterintuitive to  modern musicians, who think in terms of octaves, the concept of hexa�  chords was fundamental to music theory throughout the Middle Ages and  Renaissance.</p><p>Heydrich \'hl-drik\, Reinhard (Tristan Eugen) (b.

In 1969 he sailed a  reconstruction of an ancient Egyp�  tian reed boat (the Ra ) from Morocco  to the Caribbean to show that the  Egyptians could have had contact  with the early peoples of Central and  South America. In 1977 he took the  reed craft Tigris from the Tigris  River in Iraq across the Arabian Sea  to Pakistan and back to the Red Sea  to demonstrate the possibility of  two-way trading journeys that could  have spread ancient Sumerian cul�  ture eastward.

March 15, 1830,  Berlin, Prussia�d. April 2, 1914, Munich, Ger.) German writer. An inde�  pendent scholar, he led a circle of writers in Munich who sought to pre�  serve traditional artistic values from the encroachment of political  radicalism, materialism, and realism. His admired short stories and novel�  las were collected in numerous volumes; he also published novels, includ�  ing Children of the World (1873) and Merlin (1892), and many  unsuccessful plays. Among his best works are his translations of Giacomo  Leopardi and other Italian and Spanish poets; many were set to music by  Hugo Wolf. His popularity was already declining when he was awarded  the Nobel Prize for Literature in 1910.</p><p>Heywood, John (b. 1497?, London, Eng.?�d. after 1575, Mechelen,  Belg.) British playwright. His witty, satirical verse interludes (dialogues  on a set subject) helped put English drama on the road to the fully devel�  oped comedy of the Elizabethans. His interludes, which replace biblical  allegory with representations of everyday life and manners, include The  Play of the Wether, A Play of Love, and Wytty and Wytless (all printed  1533), and The Playe Called the Foure PP: A Palmer, a Pardoner, a  Potycary, a Pedler (printed c. 1544). He also wrote epigrams, ballads,  and a verse allegory.

Founded in  southern Lebanon in 1982 as a response to Israel�s invasion there, its  original goals were to drive Israeli troops out of Lebanon and form a  Shl'ite Islamic republic similar to that created by the Iranian revolution  of 1979. Its political stance, in the main, has been anti-Western, and its  members have been implicated in many of the terrorist activities that were  perpetrated in Lebanon during the 1980s, including kidnappings, car  bombings, and airline hijackings, a number of which were directed at U.S.  citizens. It has purportedly received strong material support from Syria  and Iran and throughout the 1990s engaged in an intensive guerrilla cam�  paign against Israeli forces in southern Lebanon. At the same time,  Hezbollah actively aided the long disfranchised Shl'ite community in  Lebanon, providing social services not offered by the government. In the  1990s the party�s candidates won seats in Lebanon�s parliamentary elec�  tions, and the group�s leaders have since sought to soften its earlier image.  Despite a unilateral withdrawal of Israeli troops from Lebanon in 2000,</p><p>the party continued sporadic attacks across the Lebanese-Israeli border.

The dates of his reign are uncertain but are often given  as 715-686 bc. He was a reformer who tried to discourage foreign cults  and assert the religious traditions of Israel during a time of AssYRiAn  supremacy. The rebellion that broke out in Palestine c. 703 bc was prob�  ably led by Hezekiah. Though he fortified Jerusalem, other cities of Judah  fell, and the revolt was put down in 701 bc. The Assyrians demanded a  heavy tribute of gold, but tradition holds that a plague devastated the  Assyrian army and Jerusalem was spared.</p><p>Hialeah \,hI-3-'le-9\ City (pop., 2000: 226,419), southeastern Florida,  U.S. Settled in 1921 by aviation pioneer Glenn Curtiss and cattleman  James H.

His story  is told in Henry W. Longfellow�s popular poem Song of Hiawatha (1855),  though Longfellow perpetuated an error of Henry Rowe Schoolcraft�s that  placed Hiawatha in a Midwestern tribe.</p><p>hibernation State of greatly slowed metabolism and low body tempera�  ture in winter in certain animals. True hibernators include many cold�  blooded animals and a few mammals (e.g., bats, hedgehogs) that go into  a near-dead state with a near-freezing body temperature and very slow  breathing and heart rate. Mammals such as bears that sleep in dens with  only slightly lowered body temperature wake easily and are not consid�  ered true hibernators. Most hibernators build up a reserve of body fat or  store food ahead of time. They may wake and eat several times during  the winter. Cold-blooded animals must hibernate where the weather drops  below freezing. Hibernation�s warm-weather equivalent is estivation.</p><p>Hiberno-Saxon style Decorative style that resulted when Irish  (Hibernian) monks went to England in 635. It mingled the Celtic deco�  rative tradition�curvilinear and �trumpet� forms, scrolls, spirals, and a  double-curve motif�with the interlaced zoomorphic patterns and bright  coloration of the pagan Anglo-Saxons. Mediterranean art entered as an  element when St. Augustine of Canterbury�s mission arrived from Rome,  introducing the human figure in art objects, but the style�s basic charac�  teristics remained geometric, with interlaced designs and areas of bright  colour, as seen in the Lindisfarne Gospels and the Book of Kells. It was  taken to Europe by Irish and Saxon Christian missionaries and there  exerted strong influence on Carolingian art.

Causes include overdistended stomach, gastric irritation,  and nerve spasms. The many folk remedies for hiccups interrupt the  rhythm of the spasms. The most common and effective treatment is to  hold the breath as long as possible. Hiccups usually stop within minutes,  though they may last days, weeks, or longer.

About 15 spe�  cies are native to eastern North America and 3 to eastern Asia. The fruit  is an egg-shaped nut enclosed in a fleshy husk. Some species�principally  shagbark hickory (C. ovata ), shellbark hickory (C. laciniosa), mockemut  hickory (C. tomentosa ), and pecan �produce large, sweet-tasting, edible  nuts. The pecan, the most valuable species economically, is cultivated for  its flavourful nuts and its light-coloured wood.

It was  part of the state of Mexico until 1869, when it was established as a sepa�  rate state in honour of the revolutionary patriot Miguel Hidalgo. Contain�  ing some of the most mountainous areas in Mexico, it has extensive  mineral deposits, including silver and gold. In pre-Columbian times it was  the centre of the Toltec civilization; an archaeological site near Tula, west  of Pachuca, is the remains of the Toltec capital. The state has major met�  alworking factories as well as agricultural production.</p><p>Hidalgo \e-'dal-go\ (y Costilla), Miguel (b. May 8, 1753, near Pen-  jamo, Guanajuato, Mex.�d. July 30, 1811, Chihuahua) Mexican priest,  called the father of Mexican independence. Ordained in 1789, he had an  uneventful early career. In the town of Dolores (now Dolores Hidalgo),  he joined a group plotting independence from Spain in the light of Napo�  leon�s invasion of that country. On Sept. 16, 1810, when his group was  betrayed, he rang the church bell and addressed his parishioners with his  Grito de Dolores (�Cry of Dolores�), calling them to revolution. Thou�  sands of Indians and mestizos joined him, and he succeeded in capturing  Guanajuato and other cities in the region before reaching Mexico City,  where his hesitation led to their defeat and his execution. The martyred  Hidalgo became a potent symbol of the independence movement that  eventually succeeded, and each September 16�now celebrated as Mexi�  co�s Independence Day�the president shouts a version of the Grito de  Dolores from the National Palace balcony.</p><p>Hidatsa \hi-'dat-so\ North American Plains Indian people of Siouan  stock living mainly on Fort Berthold Reservation in North Dakota, U.S.  They speak a Siouan language. They were mistakenly identified as a group  known to French trappers as Gros Ventres, and sometimes they are called  Gros Ventres of the Missouri. Originally the Hidatsa (whose name means  �People of the Willow�) lived on the upper Missouri River in semiper�  manent villages. They raised corn, beans, and squash and hunted bison.  Hidatsa social organization included age-graded military societies; there  were also various clans based on maternal descent. The sun dance was the  major religious ceremony. Together with the Mandan, with whom they  had peaceful relations for more than 200 years, they exchanged traditional  goods with European traders for guns, knives, and other items. In the  mid-1800s disease and war with the Dakota (Sioux) sharply reduced their  number. Only some 625 people claimed sole Hidatsa descent in the 2000  U.S. census. Together the Mandan, the Arikara, and the Hidatsa form the  Three Affiliated Tribes.</p><p>Hideyoshi See Toyotomi Hideyoshi</p><p>Hierakonpolis X.hl-o-ro-'kan-pa-bsN Ancient city, Upper Egypt.  Located south of Thebes, it was the prehistoric residence of the kings of  Upper Egypt. Now an archaeological site, it reveals the beginning of  Egypt�s historical period. It was at its height from 3400 bc to the Old  Kingdom (c. 2575 bc). Thutmose III later completely rebuilt the Archaic  temple. During the New Kingdom, el-Kab, across the river, became eco�  nomically more important, but Hierakonpolis retained its place as a reli�  gious and historical centre.</p><p>Hierapolis \ l hI-9-'ra-p9-bs\ Ancient city, now in Syria.

The standardized orthography of the Middle Kingdom (2050-1750 bc)  employed about 750 hieroglyphs. In the early centuries ad, use of hiero�  glyphs declined�the last dated text is from ad 394 �and the meaning of  the signs was lost until their decipherment in the early 19th century (see  J.-F.

His main task was to display the sacred  objects during the celebration of the mysteries and explain their secret  meaning to initiates. The priest was usually an old, celibate man with a  forceful voice, chosen from the Eumolpids, one of the original clans of  Eleusis. Upon election, he cast aside his former name and was called only  hierophantes.</p><p>hieros gamos \ , he-3- l r6s- , ga- l mos\ (Greek: �sacred marriage�) Sexual  relations of fertility deities enacted in myths and rituals, characteristic of  societies based on cereal agriculture (e.g., Mesopotamia, Phoenicia, and  Canaan). At least once a year, people dressed as gods engaged in sexual  intercourse to guarantee the fertility of the land. The festival began with  a procession to the marriage celebration, which was followed by an  exchange of gifts, a purification rite, the wedding feast, preparation of the  wedding chamber, and a secret nocturnal act of intercourse.</p><p>Higgs particle or Higgs boson Carrier of an all-pervading funda�  mental field (Higgs field) that is hypothesized as a means of endowing mass  on some elementary particles through its interactions with them.

Conventional television transmits signals  in analog form. Digital HDTV systems, by contrast, transmit pictures and  sounds in the form of digital data. These numerical data are broadcast  using the same high radio frequencies that carry analog waves, and com�  puter processors in the digital television set then decode the data. Digital  HDTV can provide sharper, clearer pictures and sound with very little  interference or other imperfections. Of perhaps greater importance, digi�  tal television sets will potentially be able to send, store, and manipulate  images as well as receive them, thereby merging the functions of the tele�  vision set and the computer.</p><p>high-energy physics See particle physics</p><p>high jump Track-and-field event of jumping for height. The equipment  includes a semicircular runway allowing an approach run of at least 49 ft  (15 m), the raised bar and its vertical supports, and a cushioned landing  area. Jumpers must leave the ground from one foot. Three failed jumps  at a height result in disqualification. Early jumping styles, including the</p><p>near-erect scissors jump and the facedown Western roll-and-straddle, were  largely superseded from 1968 by the faceup �Fosbury flop,� named for  its leading proponent, the U.S. jumper Dick Fosbury.</p><p>high place Hebrew bama. In ancient Israel or Canaan, a shrine built  on an elevated site. For Canaanites the shrines were devoted to fertility  deities, to the Baals, or to the Semitic goddesses called the Asherot. The  shrines often included an altar and a sacred object such as a stone pillar  or wooden pole. One of the oldest known high places, dating from c. 2500  bc, is at Megiddo. The Israelites also associated elevated places with the  divine presence, and after conquering Canaan they used Canaanite high  places to worship Yahweh (God). Later the Temple of Jerusalem on Mount  Zion became the only accepted high place.</p><p>high-rise building Multistory building taller than the maximum  height people are willing to walk up, thus requiring vertical mechanical  transportation. The introduction of safe passenger elevators made practi�  cal the erection of buildings more than four or five stories tall. The first  high-rise buildings were constructed in the U.S. in the 1880s. Further  developments were made possible by the use of steel structural frames  and glass curtain-wall systems. High-rises are used for residential apart�  ments, hotels, offices, and sometimes retail, light manufacturing, and edu�  cational facilities.

Although by the late 20th century  hijacking most frequently involved the seizure of an airplane and its forc�  ible diversion to destinations chosen by the air pirates, when the term was  coined in the 1920s hijacking generally referred to in-transit thefts of  truckloads of illegally manufactured liquor or to the similar seizure of  rumrunners at sea. Airplane hijacking also is known as skyjacking. The  first reported case of such hijacking occurred in Peru in 1931. Between  1968 and 1970 alone there were nearly 200 hijackings. The participants  often were politically motivated Palestinians or other Arabs who com�  mandeered airplanes while in flight and threatened harm to the passen�  gers and crew unless certain of their comrades were released from jail in  Israel or some other location. Air hijackings continued in the 1980s and  �90s, though new airport security measures and international agreements  on terrorism probably deterred many more. The deadliest act of air piracy  to date occurred on Sept. 11, 2001 (see September 11 attacks), when sui�  cide terrorists simultaneously hijacked four airliners in the U.S. and flew  two of them into the World Trade Center complex in New York City and  one into the Pentagon near Washington, D.C.; the fourth crashed outside  Pittsburgh, Pa.

Having experienced visions since child�  hood, she was eventually permitted to write Scivias (1141-52), in which  she recorded 26 prophetic, symbolic, and apocalyptic visions; it was fol�  lowed by two more such collections. She founded a convent at Rupertsberg  c. 1147, where she continued to prophesy; she became known as the �Sibyl  of the Rhine,� and her advice was sought by the most powerful and eminent  figures of Europe. Her other works include a morality play, a book of saints�  lives, treatises on medicine and natural history, and extensive correspon�  dence. Her Symphonia armonie celestium revelationum consists of 77 lyri�  cal poems, all with monophonic melodies; she is apparently the first</p><p>woman composer in the Western tradition whose music is known. Though  long regarded as a saint, she has never been formally canonized.</p><p>Hill, David Octavius, and Robert Adamson (respectively b.  1802, Perth, Scot.�d. May 17, 1870, Newington; b. 1821, Berunside,  Scot.�d. Jan. 1848, St. Andrews) Scottish photographers. Hill, originally  a painter, was a founding member of the Royal Scottish Academy and its  secretary for 40 years. In 1843 he enlisted the help of Adamson, a chemist  experienced in photography, in photographing the delegates to the found�  ing convention of the Free Church of Scotland. They used the calotype pro�  cess, by which an image was developed from a paper negative. In these and  other portraits they demonstrated a masterly sense of form and composition  and a dramatic use of light and shade. Their five-year partnership resulted  in some 3,000 photographs, including many views of Edinburgh and small  fishing villages. Before Adamson died at age 27, they produced some of the  greatest photographic portraits of the 19th century.</p><p>Hill, James J(erome) (b. Sept. 16, 1838, near Guelph, Ont., Can.�d.  May 29, 1916, St. Paul, Minn., U.S.) Canadian-U.S. financier and rail�  road builder. He began his career in St. Paul overseeing steamboat trans�  portation. In 1873 he reorganized a bankrupt railroad as the St. Paul,  Minneapolis, and Manitoba Railway Co. and was named its president in  1882. The Great Northern Railway Co. absorbed the St. Paul line in 1890,  and Hill became its president (1893-1907) and chairman of the board  (1907-12). The Northern Pacific and the Chicago, Burlington and Quincy  railroads also came under Hill�s control; Edward Harriman�s attempt to  seize control of Northern Pacific from him (1901) triggered a Wall Street  panic. Hill�s banking activity as president of Northern Securities Co. was  declared in violation of the Sherman Antitrust Act in 1904.</p><p>Hill, Joe orig. Joel Emmanuel Hagglund (b. Oct. 7, 1879, Gavle,  Swed.�d. Nov. 19, 1915, Salt Lake City, Utah, U.S.) Swedish-U.S. song�  writer and organizer for the Industrial Workers of the World (IWW). Hill  immigrated to the U.S. c. 1902 and joined the IWW in 1910. His songs of  protest and solidarity�including �The Preacher and the Slave,� in which  he coined the phrase pie in the sky to mock the �reward� awaiting the meek  in the next world�became widely popular. In 1914 he was arrested in Salt  Lake City and charged with the murder of a grocer and his son during a  robbery. Convicted on circumstantial evidence despite mass demonstra�  tions on his behalf, Hill was executed by a firing squad. His death made him  a martyr in the eyes of the radical U.S. labour movement.</p><p>Hill painting See Pahari painting</p><p>Hillary, Sir Edmund (Percival) (b. July 20, 1919, Auckland, N.Z.)  New Zealand mountain climber and  explorer. Hillary was a professional  beekeeper but enjoyed climbing in  the New Zealand Alps. In 1951 he  joined a New Zealand party to the  central Himalayas and then went on  to help in a reconnaissance of the  southern flank of Everest. In 1953, as  a member of the British Everest  expedition, he and Tenzing Norgay  reached the summit on May 29,  becoming the first known climbers to  do so. The achievement brought Hil�  lary worldwide fame and he was  knighted that same year. In 1958 he  participated in the first crossing of  Antarctica by vehicle. From the  1960s he has helped build schools  and hospitals for the Sherpa people.</p><p>Hillel (fl. 1st century bc-c. first  quarter of the 1st century ad) Jewish  sage and architect of rabbinic Judaism. Born in Babylonia, he went to Pal�  estine to complete his studies under the Pharisees. He became the revered  head of the school known by his name, the House of Hillel, and his care�  fully applied method of exegesis came to be called the Seven Rules of  Hillel. He liberated texts from a slavish literal interpretation and sought  to make obedience to the Law feasible for all Jews. His legal writings  were very influential in the compilation of the Talmud, which also contains  many stories and legends about his life. He is remembered as a model  scholar and communal leader, whose brilliance, patience, and goodness  are to be emulated by all rabbis.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>876 I Hilliard &#x25BA; Hindemith</p><p>Hilliard Vhil-yardV Nicholas (b. 1547, Exeter, Eng.�d.

He produced many portraits of her and of  such members of her court as Francis Drake and Walter Raleigh. He  retained his appointment on the accession of James I (1603), while also  practicing as a goldsmith and jeweler. The first great native-born English  painter of the Renaissance, he raised the art of miniature painting to its high�  est point of development and influenced English portraiture through the  early 17th century.</p><p>Hillman, Sidney orig. Simcha Hillman (b. March 23, 1887,  Zagare, Lith.�d. July 10, 1946, Point Lookout, N.Y., U.S.) Lithuanian-  born U.S. labour leader. He immigrated to the U.S. in 1907, became a  garment worker, and was elected president of the Amalgamated Clothing  Workers of America in 1914. Under his leadership the union greatly  increased its membership, secured unemployment insurance, and orga�  nized two banks. He served in various New Deal labour organizations,  including the National Recovery Administration. Hillman also helped found  the Congress of Industrial Organizations and was active in it until his  death. See also AFL-CIO; John L. Lewis.</p><p>Hillquit, Morris orig. Morris Hillkowitz (b.

He  immigrated to the U.S. in 1886, joined the Socialist Labor Party, and  helped found the United Hebrew Trades in 1888. When the party split,  he led a moderate faction to help form the Social Democratic Party, which  in 1901 became the Socialist Party. As the party�s chief theoretician, he  defined its position of pacifism during World War I and defended many  socialists in court. He was twice the Socialist Party�s unsuccessful can�  didate for mayor of New York (1917, 1932).</p><p>Hilton, Conrad (Nicholson) (b. Dec. 25, 1887, San Antonio, N.M.,  U.S.�d. Jan. 3,1979, Santa Monica, Calif.) U.S. businessman, founder of  one of the world�s largest hotel organizations. As a boy he helped his father  turn the family�s adobe house into an inn for traveling salesmen. After his  father�s death in 1918 he bought several hotels in Texas, and by 1939 he  was building, leasing, and buying hotels in California, New York, Illinois,  and elsewhere. In 1946 the Hilton Hotels Corp. was organized; in 1948, as  the business expanded overseas, the company was renamed Hilton Inter�  national Co. Later diversification included a credit card company and a car-  rental firm. His son Barron succeeded him as president in 1966.</p><p>Hilton, James (Glen Trevor) (b.

Edu�  cated at Cambridge University, he later wrote numerous novels but is  principally remembered for three best-selling works that led to popular  films: Lost Horizon (1933; film, 1937), Good-Bye Mr. Chips (1934; film,  1939), and Random Harvest (1941; film, 1942). He eventually moved to  California to work as a screenwriter.</p><p>Himachal Pradesh Mio-'ma-chol-pro-'deslA State (pop., 2001 prelim.:  6,077,248), northern India. Located in the western Himalayas, it is bor�  dered by Tibet (China) and the states of Uttaranchal, Haryana, Punjab, and  Jammu and Kashmir and covers an area of 21,495 sq mi (55,673 sq km);  its capital is Shimla. The area�s history dates back to the Vedic period; later  the Aryans assimilated the indigenous peoples. It was exposed to succes�  sive invasions through the centuries, ending with British domination in  the 19th century. Between 1948 and the achievement of statehood in 1971,  the state underwent various changes in size and administrative status. It  is one of the least urbanized states in India, and most of the people are  subsistence-level farmers.</p><p>Himalayas ^hi-mo-Ta-oz, hi-'ma-b-yozV or Himalaya Mountain  system, southern Asia. It forms a barrier between the Plateau of Tibet to  the north and the plains of the Indian subcontinent to the south. It con�  stitutes the greatest mountain system on Earth and includes more than  110 peaks rising to elevations above 24,000 ft (7,300 m), including Mount  Everest. The system extends some 1,550 mi (2,500 km) from east to west  and covers about 230,000 sq mi (595,000 sq km). It is traditionally divided  into four parallel ranges: from north to south, the Tethys (or Tibetan)  Himalayas, the Great Himalayas (including the major peaks), the Lesser  Himalayas (including peaks of 12,000-15,000 ft [3,700-4,500 m]), and  the Outer Himalayas (including the lowest peaks). Between the eastern  and western extremities of the broad Himalayan arc lie several Indian  states and the kingdoms of Nepal and Bhutan. It acts as a great climatic  divide, causing heavy rain and snow on the Indian side but aridity in Tibet,</p><p>and represents at many points a virtually impassable barrier, even by air.  The mountains� glaciers and snows are the source of 19 major rivers,  including the Indus, Ganges (Ganga), and Brahmaputra.</p><p>Himera Vhi-m9-r9\ Ancient Greek city, northern coast of Sicily. It was  founded c. 649 bc by Syracusan exiles and Chalcidian inhabitants of Zan-  cle (see Messina). An unsuccessful Carthaginian invasion of Sicily ended  in the death of Hamilcar at the Battle of Himera in 480 bc. It was finally  destroyed in 409 bc by Hamilcar�s grandson Hannibal. Its only visible relic  is a Doric temple (480 bc); many of its lion-head spouts are exhibited in  the Palermo Museum.</p><p>Himmler, Heinrich (b. Oct. 7, 1900, Munich, Ger.�d. May 23, 1945,  Liineburg) German Nazi police  administrator who became the sec�  ond most powerful man in the Third  Reich. He joined the Nazi Party in  1925 and rose to become head of  Adolf Hitler�s SS. He was put in com�  mand of most German police units  after 1933, taking charge of the  Gestapo in 1934, and established the  Third Reich�s first concentration  camp, at Dachau. He soon built the  SS into a powerful network of state  terror, and by 1936 he commanded all  the Reich�s police forces. In World  War II he expanded the Waffen-SS  (Armed SS) until it rivaled the army;  after 1941 he organized the death  camps in eastern Europe. Shunted  aside by Hitler�s entourage, Him�  mler, hoping to succeed Hitler, had  negotiations with the Allies in the  final months of the war over Germa�  ny�s surrender or its alliance with the  Western Allies against the Soviet  Union. Hitler ordered his arrest, but when he attempted to escape he was  captured by the British and committed suicide by taking poison.</p><p>Hims \'hims\ or Homs \'homs\ ancient Emesa City (pop., 2004 est.:  800,400), central Syria. It is located near the Orontes River. As Emesa, it  contained a large temple to the sun god El Gebal and was the birthplace  of the priest-king Elagabalus, who became Roman emperor in ad 218. The  emperor Aurelian defeated Queen Zenobia of Palmyra there in 272. It was  taken in 636 by the Muslims, who renamed it Hims. In 1516 it passed into  Ottoman hands, where it remained (except for a brief period of Egyptian  control in the 1830s) until the creation of Syria after World War I (1914�  18). Hims is a thriving agricultural market centre and has oil and sugar  refineries. It is the central link between the interior cities and the Medi�  terranean Sea coast.</p><p>Hinayana V.he-no-'ya-noV Name given to the more conservative schools  of Buddhism. A Sanskrit word meaning �Lesser Vehicle� (because it is  concerned with the individual�s salvation), it was first applied pejoratively  to the established Buddhist schools by followers of the more liberal  Mahayana (�Greater Vehicle,� because it is concerned with universal sal�  vation) tradition. The ancient Hinayana schools continued to prosper after  the rise of the Mahayana in the 1st century ad, but Theravada Buddhism  was the only Hinayana school that maintained a strong position after the  collapse of Indian Buddhism in the 13th century.</p><p>Hincmar of Reims \ , hiqk-,mar... , remz\ (b. c. 806, northern  France?�d. Dec. 21, 882, Epernay, near Reims) French archbishop and  theologian. The most influential churchman of the 9th century, he advised  the Carolingian emperors Louis I and Charles II and was chosen archbishop  of Reims in 845. He maintained his influence despite the hostility of  Lothar I, whose divorce Hincmar staunchly opposed, and secured the suc�  cession of Charles to the throne of Lotharingia. Hincmar also rallied the  church to the defense of Charles when Louis the German invaded the  kingdom in 858. His theological writings included treatises on predesti�  nation, in which he argued that God does not damn a sinner in advance,  and a defense of the Christian opposition to divorce.</p><p>Hindemith Vhin-do-.mitV, Paul (b.

He became con-  certmaster of the Frankfurt Opera at age 20, and his compositions began  drawing attention at new-music festivals. Because his wife was Jewish  and his music was considered �degenerate� by the Nazis, he left Germany  in 1938, settling in the U.S. in 1940. Advocating Gebrauchsmusik (�use�  ful music�), he wrote solo sonatas and concertos for many of the standard  orchestral instruments. Mathis der Maler (1935) is the best known of his  six operas; the symphony based on it, and the Symphonic Metamorpho�  sis on Themes of Weber (1943), are widely performed.</p><p>Hindenburg, Paul von in full Paul Ludwig Hans Anton von  Beneckendorff und von Hin�  denburg (b.

Born to an aristo�  cratic family, he retired from the  Prussian army as a general in 1911.</p><p>Recalled to duty in World War I, he  commanded German forces in East  Prussia and became a national hero  after the Battle of Tannenberg (1914).</p><p>With Erich Ludendorff as his chief  aide, he nominally commanded all  German forces until the end of the  war, then retired again in 1919. Sup�  ported by conservative groups, he  was elected president of Germany in  1925. When the Great Depression led  to a political crisis, he was pressured  to make the government more inde�  pendent of parliamentary controls. In  1930 he allowed Chancellor Heinrich  Bruning to dissolve the Reichstag,  and in the new elections the Nazi Party emerged as the second largest  party. In 1932 Hindenburg was reelected president by opponents of the  Nazis; however, his advisers considered the Nazis useful, and in 1933 he  was persuaded to appoint Adolf Hitler chancellor.</p><p>Hindenburg disaster Explosion of the dirigible Hindenburg, the  largest rigid airship ever constructed. Launched in 1936 in Germany, it  started the first commercial air service across the North Atlantic and made  10 successful round trips. On May 6, 1937, as it was landing in Lake-  hurst, N.J., U.S., its hydrogen gas burst into flames, destroying the air�  ship and killing 36 of the 97 persons aboard. The disaster, recorded on  film and phonograph disk, effectively ended the use of rigid airships in  commercial transportation.</p><p>Hindi language Indo-Aryan ianguage of India, spoken or understood  by more than 30% of the country�s population. Modern Standard Hindi is  a lingua franca (as well as native language) of millions of people in North  India and the official language of the Indian Union. It is effectively a con�  tinuation of Hindustani, which developed from Khari Boli, the speech of  certain classes and districts in Delhi affiliated with the Mughal court in the  16th�18th centuries. A heavily Persianized variant of Khari Boli used by  Muslim authors formed the basis for Urdu. Hindustani was codified by the  British at Fort William College in Calcutta (now Kolkata). There Hindu  intellectuals promoted a Sanskritized form of Hindustani (see Sanskrit lan�  guage) written in the Devanagari script (see Indic writing systems) in the late  18th and early 19th centuries; it became the progenitor of modem literary  Hindi as used by Hindu authors. During the Indian independence move�  ment, Hindustani was regarded as a national unifying factor, but after the  partition in 1947 this attitude changed, and the name has practically  dropped from use in favour of either Hindi or Urdu. Linguists, particularly  George Abraham Grierson, have also used the term Hindi to refer collec�  tively to all the dialects and regional literary languages of the northern  Indian plain. Hindi has drastically simplified the complex grammar of Old  Indo-Aryan while preserving certain phonetic features.</p><p>Hindu-Arabic numerals Set of 10 symbols�1, 2, 3, 4, 5, 6, 7, 8, 9,  0�that represent numbers in the decimal number system. They originated  in India in the 6th or 7th century and were introduced to Europe through  Arab mathematicians around the 12th century (see al-Khwarizmi). They  represented a profound break with previous methods of counting, such as  the abacus, and paved the way for the development of algebra.</p><p>Hindu Kush Vhin-du-'kush\ Latin Caucasus Indicus Mountain sys�  tem, south-central Asia. Some 500 mi (800 km) long, it runs from the  Pamirs in the east near the Pakistan-China border through Pakistan to  western Afghanistan. The system forms a drainage divide between the  Amu Darya (ancient Oxus River) valley to the northwest and the Indus  River valley to the southeast. Its passes have historically been of great  military significance, providing access to the northern plains of the Indian  subcontinent. It includes about two dozen summits above 23,000 ft (7,000  m), including the highest, Tirich Mir, at 25,230 ft (7,690 m).</p><p>Hinduism Oldest of the world�s major religions. It evolved from the  Vedic religion of ancient India. The major branches of Hinduism are Vaish-  navism and Shaivism, each of which includes many different sects. Though  the various sects each rely on their own set of scriptures, they all revere  the ancient Vedas, which were brought to India by Aryan invaders after  1200 bce. The philosophical Vedic texts called the Upanishads explored  the search for knowledge that would allow mankind to escape the cycle  of reincarnation. Fundamental to Hinduism is the belief in a cosmic prin�  ciple of ultimate reality called Brahman and its identity with the individual  soul, or atman. All creatures go through a cycle of rebirth, or samsara,  which can be broken only by spiritual self-realization, after which libera�  tion, or moksha, is attained. The principle of karma determines a being�s  status within the cycle of rebirth. The greatest Hindu deities are Brahma,  Vishnu, and Shiva. The numerous other Hindu gods are mostly viewed as  incarnations or epiphanies of the main deities, though some are survivors  of the pre-Aryan era. The major sources of classical mythology are the  Mahabharata (which includes the Bhagavadgita, the most important reli�  gious text of Hinduism), the Ramayana, and the Puranas. The hierarchi�  cal social structure of the caste system is also important in Hinduism; it  is supported by the principle of dharma. In the 20th century Hinduism  blended with Indian nationalism to become a powerful political force in  Indian politics. In the early 21st century there were more than 850 mil�  lion Hindus worldwide.</p><p>Major Hindu Holidays</p><p>Date</p><p>Name</p><p>Significance</p><p>Caitra (Mar.-Apr.)

In 1911  he was hired by the National Child Labor Committee to record child  labour conditions. Traveling throughout the East, he produced appalling  pictures of exploited children. In World War I he worked as a photogra�  pher with the Red Cross. On returning to New York City, he photographed  the construction of the Empire State Building.

U.S. pianist and bandleader who had a  profound influence on the development of jazz piano. Known as �Fatha�  Hines, he was a pianist of amazing technical command and tireless energy.  Breaking with the stride tradition (in which regular two-beat left-hand  rhythms accompany the melody in the right hand), he emulated the single�  note instruments (e.g., trumpet) in creating melodic variations of the  melody with the right hand. Hines led a successful Chicago-based big  band from 1928 to 1948. He was influenced by Louis Armstrong, and the  two performed together frequently throughout their careers; their recorded  encounters from the late 1920s, particularly �Weather Bird,� are jazz clas�  sics.</p><p>hip-hop See rap</p><p>Hipparchus or Hipparchos \hi-'par-kos\ (b.

He discov�  ered the precession of the equinoxes (see equinoxes, precession of the), cal�  culated the length of the year to within 6.5 minutes, compiled the first  known star catalog, and made an early formulation of trigonometry. His  observations were painstaking and extremely accurate. He rejected all  astrology but also Sun-centred views of the universe; his views had a pro�  found influence on Ptolemy. His star catalog logged the positions of the  stars in terms of celestial coordinates, listed about 850 stars, and specified  their brightnesses by a system of six magnitudes similar to today�s. He  adequately accounted for the irregularities in the Moon�s motion that are  due to its elliptical orbit. His main contribution to geography was to apply  rigorous mathematical principles to the determination of places on Earth�s  surface, and he was the first to do so by specifying latitude and longitude.</p><p>Hippias (d. 490 bc) Tyrant of Athens (528/527-510). He succeeded his  father, Peisistratus, as tyrant. Hippias was a patron of poets and craftsmen,  and Athens prospered under his rule, but he became repressive after the  assassination of his brother Hipparchus (514). He was overthrown by the  Spartans (510) and went into exile in Asia Minor. He went with the Per�  sians to attack the Athenians, and it  was he who advised Darius I in 490  to land at Marathon, which resulted  in a major Persian defeat.</p><p>Hippocrates \hi-'pa-kr3-,tez\ (b.  c. 460 bc, island of Cos, Greece�d.  c. 377, Larissa, Thessaly) Greek  physician regarded as the father of  medicine.

It com�  monly reaches a length of 11.5 ft (3.5 m), a height of 5 ft (1.5 m) at the  shoulder, and a weight of 7,000 lb (3,200 kg). The skin is very thick,  nearly hairless, and grayish brown above, lighter and pinkish below. The  ears and nostrils protrude above water when the rest of the body is sub�  merged. Hippopotamuses live near rivers, lakes, swamps, or other per�  manent bodies of water, usually in groups of 7 to 15. During the day they  sleep and rest in or near the water. At night they go on land to feed on  grasses, which they crop with their hard-edged lips. In water they can  swim fast, walk along the bottom, and remain submerged (with ears and  nostrils closed) for five minutes or more. The rare pygmy hippopotamus  {Hexaprotodon liberiensis) is the only other species of the family Hippo-  potamidae. Living along streams and in wet forests and swamps of West  Africa, it is about the size of a domestic pig.</p><p>HIrah Yhir-oV Al- Ancient city, Middle East. Located near present-day  Al-Kufah in south-central Iraq, in the 5th-6th centuries ad it was the  capital of the Lakhmid dynasty, which itself was subordinate to the Sasa-  NlAN dynasty of Persia. The city was a diplomatic, political, and military  centre and an important station on the Persia-Arabia caravan route. Tra�  dition holds that the Arabic script was developed there. Also the seat of  a bishopric for Nestorian Christians, it promoted Christian monotheism  in the Arabian Peninsula. Al-Hlrah began to decline following the collapse  of the Lakhmids early in the 7th century, and in 633 the city was taken  by the Muslims.</p><p>Hirata Atsutane \,he- , ra-ta- 1 a-tsu- , ta-na\ (b. Sept. 25, 1776, Akita,  Japan�d. Oct. 4, 1843, Akita) Leader of the Japanese Restoration Shinto  school. He settled in Edo (modern Tokyo) at age 20 and became a dis�  ciple of Motoori Norinaga. Hirata sought to develop a Shinto theologi�  cal system offering principles for social and political action. He  proclaimed the natural superiority of Japan and championed the imperial  line. For criticizing the Tokugawa shogunate (see Tokugawa period), which  had reduced the emperor to a powerless symbol, he was punished by being  confined to his birthplace for the rest of his life. His theories helped bring  about the shogunate�s overthrow, and he influenced 20th-century Shinto  and Japanese nationalism.</p><p>Hirohito \,hir-o-'he-to\ or Showa \'sho-o\ emperor (b. April 29,  1901, Tokyo, Japan�d. Jan. 7, 1989, Tokyo) Longest-reigning of Japan�s  monarchs (1926-89). His rule coincided with Japan�s 20th-century mili�  tarism and its aggression against China and Southeast Asia and in the  Pacific Ocean during World War II. Though the Meiji Constitution invested  the emperor with supreme authority, in practice he merely ratified the  policies formulated by his ministers and advisers. Historians have debated  whether Hirohito could have diverted Japan from its militaristic path and  what responsibility he should bear for the actions of the government and  military during the war. In August 1945 he broke the precedent of impe�  rial silence when he made a national radio broadcast to announce Japan�s  surrender, and in 1946 he made a second broadcast to repudiate the tra�  ditional quasi-divine status of Japan�s emperors.

Oct. 12, 1858, Edo) Japanese artist and master of the colour  woodblock print. He became a pupil of the ukiyo-e master Utagawa Toy-  okuni in Edo (now Tokyo) c. 1811. In 1833-34 a series of 55 landscape  prints, Fifty-three Stages on the Tokaido, established him as one of the  most popular ukiyo-e artists of all time. Demand for his figure-with-  landscape designs became so great that overproduction diminished their  quality. He produced more than 5,000 prints, and 10,000 copies were  made from some of his woodcuts. His genius was first recognized in the  West by the Impressionists and Post-Impressionists, on whom he exerted  much influence.

In his Nineteen  Letters of Ben Uziel (1836), he expounded his system of Neo-Orthodoxy,  which helped make Orthodox Judaism viable in 19th-century Germany.  He advocated blending strict schooling in the Torah with modern secular  education, and he argued that Orthodox Jews should separate from the  larger Jewish community in defense of their traditions. His many works  include commentaries on the Pentateuch and an Orthodox textbook on  Judaism.</p><p>Hirschfeld, Al(bert) (b. June 21, 1903, St. Louis, Mo., U.S.�d. Jan.  20, 2003, New York, N.Y.) U.S. caricaturist. He lived mostly in New York  City. He studied art in Europe and traveled in East Asia, where Japanese  and Javanese art influenced his graphic style. He was especially known  for his stylish caricatures in the New York Times over many decades  (beginning 1929) portraying show-business personalities, in which read�  ers enjoyed hunting for the name of his daughter, Nina. Hirschfeld also  illustrated many books and produced watercolours, lithographs, etchings,  and sculptures.</p><p>His \'his\, Wilhelm (b. Dec. 29, 1863, Basel, Switz.�d.

His father, Wilhelm His (1831-1904), first  realized that each nerve fibre stems from a single neuron and invented the  microtome, a device used to slice thin tissue sections for microscopic  examination. The younger His discovered (1893) the specialized muscle  fibres (bundle of His) running along the septum between the heart�s left  and right chambers. He found that they help communicate a single rhythm  of contraction to all parts of the heart, and he was one of the first to rec�  ognize that the heartbeat originates in individual cells of heart muscle.</p><p>Hispaniola \,his-p3n-'yo-l9\ Spanish Espanola \,es-pa-'nyo-la\  Island, central West Indies. The second-largest West Indian island, it lies  east of Cuba. It is divided into Haiti to the west and the Dominican  Republic to the east. The island is some 400 mi (650 km) long and 150  mi (241 km) wide at its widest point. Christopher Columbus landed there  in 1492. The Spanish wiped out the natives and settled the island with  African slaves. In 1795 Spain ceded the eastern two-thirds of the island  to France. The slaves rebelled in the late 18th century; led by Toussaint-  Louverture and J.-J. Dessalines, they formed the independent Republic of  Haiti (1804) on the western part of the island. The eastern part was briefly  reunited with Spain; its road to eventual independence as the Dominican  Republic (1844) was initially blocked by Haitian dominance.</p><p>Hiss, Alger (b. Nov. 11, 1904, Baltimore, Md., U.S.�d. Nov. 15, 1996,  New York, N.Y.) U.S. government official. He attended Harvard Law  School and clerked for Oliver Wendell Holmes, Jr. He worked at the U.S.  State Department in the 1930s, attended the Yalta Conference (1945) as  an adviser to Pres. Franklin D. Roosevelt, was briefly secretary-general of  the fledgling UN, and served as head of the Carnegie Endowment for  International Peace (1946^-9). In 1948 Whittaker Chambers testified  before the House Un-American Activities Committee (HUAC) that Hiss had  been a fellow member of a communist spy ring in the 1930s. When  Chambers repeated the charge in public, unprotected by congressional</p><p>immunity, Hiss sued him for slander. In a federal grand-jury investigation  of the case, both Chambers and Hiss testified; Hiss was later indicted on  two charges of perjury. His first trial (1949) ended with a hung jury; at  his second trial (1950) he was found guilty. He was released from jail in  1954, still protesting his innocence. In 1996 the release of secret Soviet  cables intercepted by U.S. intelligence during World War II provided  strong evidence of Hiss�s guilt. The Hiss case seemed to lend substance  to charges by Sen. Joseph McCarthy of communist infiltration in the State  Department; it also brought national attention to Richard Nixon, whose  hostile questioning of Hiss during the HUAC hearings did much to estab�  lish his reputation as a fervent anticommunist.</p><p>histamine \ l his-t3- l men\ Organic compound found in nearly all animal  tissues, in microorganisms, and in some plants. Its release stimulates many  smooth muscles to contract, such as those in the gastrointestinal tract,  uterus, and the bronchi. It causes fine blood vessels to dilate and become  more permeable, causing the runny nose, watery eyes, and tissue swell�  ing of hay fever and some other allergies. Histamine appears to have a  physiological role in the body�s defenses against a hostile environment,  since it may be released when the body is subjected to trauma, infection,  or some drugs. Under extreme circumstances, the effects of histamine lead  to exaggerated responses with distressing results, as may occur in some  allergic conditions (see anaphylaxis). Stinging nettles and certain insect  venoms contain histamine. In humans, histamine is formed by removal of  a carboxyl group from histidine. Its effects are counteracted by antihista�  mines.</p><p>histidine Vhis-t3-,den\ One of the essential amino acids, first isolated in  1896.

Along with the pie chart, the histogram  is the most common format for representing statistical data. Its advantage  is that it not only clearly shows the largest and smallest categories but  gives an immediate impression of the distribution of the data. In fact, a  histogram is a representation of a frequency distribution.</p><p>histology \his-'ta-l3-je\ Branch of biology concerned with the compo�  sition and structure of plant and animal tissues in relation to their spe�  cialized functions.

Two major tendencies in history writing are evident from  the beginnings of the Western tradition: the concept of historiography as  the accumulation of records and the concept of history as storytelling,  filled with explanations of cause and effect. In the 5th century bc the Greek  historians Herodotus and, later, Thucydides emphasized firsthand inquiry in  their efforts to impose a narrative on contemporary events. The dominance  of Christian historiography by the 4th century introduced the idea of world  history as a result of divine intervention in human affairs, an idea that  prevailed throughout the Middle Ages in the work of such historians as  Bede. Humanism and the gradual secularization of critical thought influ�  enced early modern European historiography. The 19th and 20th centu�  ries saw the development of modem methods of historical investigation  based on the use of primary source materials. Modern historians, aiming  for a fuller picture of the past, have tried to reconstruct a record of ordi�  nary human activities and practices; the French Annales school has been  influential in this respect.</p><p>history, philosophy of Branch of philosophy concerned with ques�  tions about the meaningfulness of history and the nature of historical  explanation. Philosophy of history in the traditional sense is conceived to  be a first-order inquiry, its subject matter being the historical process as</p><p>Cenotaph in Peace Memorial Park,  Hiroshima, Japan; Atomic Bomb Dome  is visible through the arch.</p><p>BOB GLAZE�ARTSTREET</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>880 I history play &#x25BA; Hmong-Mien</p><p>a whole and its broad aim being to provide an overall elucidation of its  course.

Aug. 13, 1899, London, Eng.�d. April 29,  1980, Bel Air, Calif., U.S.) British-born film director. He worked in the  London office of a U.S. film company from 1920 and was promoted to  director in 1925. His film The Lodger (1926) concerned an ordinary per�  son caught in extraordinary events, a theme that was to recur in many of  his films. Fascinated with voyeurism and crime, he proved himself a mas�  ter of suspense with The Man Who Knew Too Much (1934; remade 1956),  The 39 Steps (1935), and The Lady Vanishes (1938). His first U.S. film,  Rebecca (1940), was a tense psychological drama. His virtuosity was evi�  dent in his later films Lifeboat (1944), Spellbound (1945), Notorious  (1946), Rear Window (1954), Vertigo (1958), North by Northwest (1959),  Psycho (1960), The Birds (1963), and Frenzy (1972).</p><p>Hitchings, George Herbert (b.

Over nearly 40 years, he and Gertrude  Elion designed a variety of new drugs that work by interfering with repli�  cation or other vital functions of specific disease-causing agents; these  drugs include those to treat leukemia, severe rheumatoid arthritis and other  autoimmune diseases (also useful for suppressing rejection after organ  transplants), gout, malaria, urinary and respiratory-tract infections, and  herpes simplex. In 1988 he shared a Nobel Prize with Elion and James Black.</p><p>Hitler, Adolf (b. April 20, 1889, Braunau am Inn, Austria�d. April 30,  1945, Berlin, Ger.) Dictator of Nazi Germany (1933^-5). As a soldier in  the German army in World War I, he was wounded and gassed. In 1920  he became head of propaganda for the renamed National Socialists (Nazi  Party) and in 1921 party leader. He set out to create a mass movement,  using unrelenting propaganda. The party�s rapid growth climaxed in the  Beer Hall Putsch (1923), for which he served nine months in prison; there  he started to write his virulent autobiography, Mein Kampf. Believing that  �races� were unequal and that this was part of the natural order, he exalted  the �Aryan race� while propounding anti-Semitism, anticommunism, and  extreme German nationalism. The economic slump of 1929 facilitated  Hitler�s rise to power. In the Reichstag elections of 1930 the Nazis became  the country�s second largest party and in 1932 the largest. Hitler ran for  president in 1932 and lost but entered into intrigues to gain power, and  in 1933 Paul von Hindenburg invited him to be chancellor. Adopting the  title of Ftihrer (�Leader�), Hitler gained dictatorial powers through the  Enabling Act and suppressed opposition with assistance from Heinrich Him�  mler and Joseph Goebbels. Hitler also began to enact anti-Jewish measures,  which culminated in the Holocaust. His aggressive foreign policy led to  the signing of the Munich Agreement with France, Britain, and Italy, which  permitted German annexation of Czechoslovakia�s Sudetenland. He  became allied with Benito Mussolini in the Rome-Berlin Axis. The  German-Soviet Nonaggression Pact (1939) enabled him to invade Poland,  precipitating World War II. As defeat grew imminent in 1945, he married  Eva Braun in an underground bunker in Berlin, and the next day they  committed suicide.</p><p>Hitler-Stalin Pact See German-Soviet Nonaggression Pact</p><p>Hitler Youth German Hitler-Jugend \,yii-gent\ Organization set up  by Adolf Hitler in 1933 for educating and training male youths aged 13-18  in Nazi principles.

Though compelled by the  government to ally itself with Shinto, Hito-no-michi continued its unortho�</p><p>dox teachings and gathered a following of more than 600,000 by 1934. It  was ordered disbanded in 1937; Tokuharu and his son Miki Tokuchika were  jailed, and Tokuharu died the next year. In 1945 Miki Tokuchika was  released, and he revived the sect under the name PL Kyodan.</p><p>Hitomaro See Kakinomoto no Hitomaro</p><p>Hittite \'hi-,tlt\ Any member of an Indo-European people whose empire  (Old Kingdom c. 1700-1500 bc, New Kingdom c. 1400-1180 bc) was  centred in Anatolia and northern Syria. Old Kingdom records detail Hit�  tite territorial expansion; New Kingdom documents contain accounts of  the Battle of Kadesh, one of the greatest conflicts of the ancient world,  which was fought against Egypt. Hittite kings had absolute power and  were viewed as deputies of the gods, at death becoming gods themselves.  Hittite society was feudal and agrarian; iron-working technology was  developed. The kingdom fell abruptly, possibly because of large-scale  migrations of Sea Peoples and Phrygians into parts of the empire.</p><p>HIV in full human immunodeficiency virus Retrovirus associated  with AIDS. HIV attacks and gradually destroys the immune system, leaving  the host unprotected against infection. It cannot be spread through casual  contact but instead is contracted mainly through exposure to blood and  blood products (e.g., by sharing hypodermic needles or by accidental  needle sticks), semen and female genital secretions, or breast milk. A  pregnant woman can pass the virus to her fetus across the placenta. The  virus first multiplies in lymph nodes near the site of infection. Once it  spreads through the body, usually about 10 years later, symptoms appear,  marking the onset of AIDS. Multidrug �cocktails� can delay onset, but  missing doses can lead to drug resistance. Like other viruses, HIV needs  a host cell to multiply. It attacks helper T cells and can infect other cells.  A rapid mutation rate helps it foil both the immune system and treatment  attempts. No vaccine or cure exists. Abstinence from sex, use of condoms  or other means to prevent sexual transmission of the disease, and avoid�  ance of needle sharing have reduced infection rates in some areas.</p><p>hives or urticaria X.ort-o-'kar-e-oV Allergic skin reaction in which  slightly raised, flat-topped, very itchy swellings appear suddenly. The  acute form, probably most often caused by food allergies, subsides in 6-24  hours, but the chronic form, believed to be due to emotional and mental  stress, lasts much longer. Acute hives may also be triggered by drugs,  especially penicillin, inhaled allergens or toxins, or diseases. Treatment  involves identifying and avoiding the allergen; epinephrine and antihista�  mines may help the acute skin symptoms.</p><p>Hiwassee \hl-'wa-se\ River River, southeastern U.S. Rising in the Blue  Ridge in northern Georgia, it flows 132 mi (213 km) into North Carolina  and southeastern Tennessee to join the Tennessee River at the Chickamauga  Reservoir.

In the after-  math of the Indochina wars that ended in 1975, many Hmong fled from  Laos to Thailand. Some were eventually resettled in the U.S., which now  has perhaps 150,000 Western dialect speakers. Mien (Yao) has three major  dialects; the largest of which, also called Mien, accounts for about 85%  of Mien speakers.

Son of a poor scholar, he was  brought up in a rural village. In 1911 he found work on a French steamer  and traveled the world, then spent six years in France, where he became a  socialist. In 1923 he went to the Soviet Union; the next year he went to  China, where he started organizing exiled Vietnamese. He founded the  Indochina Communist Party in 1930 and its successor, the Viet Minh, in  1941. In 1945 Japan overran Indochina, overthrowing its French colonial  rulers; when the Japanese surrendered to the Allies six months later, Ho and  his Viet Minh forces seized the opportunity, occupied Hanoi, and pro�  claimed Vietnamese independence. France refused to relinquish its former  colony, and the First Indochina War broke out in 1946. Ho�s forces defeated  the French in 1954 at Dien Bien Phu, after which the country was parti�  tioned into North and South Vietnam. Ho, who ruled in the north, was soon  embroiled with the U.S.-backed regime of Ngo Dinh Diem in the south in  what became known as the Vietnam War; North Vietnamese forces pre�  vailed over the south six years after Ho�s death.</p><p>Ho Chi Minh City formerly Saigon \'sl-,gan\ City (pop., 1999 est.:  4,549,000), southern Vietnam.

In 1862 the area, includ�  ing the town, was ceded to France. After World War II Vietnam declared  its independence, but French troops seized control and the First Indo�  china War began. The Geneva conference in 1954 divided the country,  and Saigon became the capital of South Vietnam.

Meyndert Lub-  bertsz(oon) (baptized Oct. 31, 1638, Amsterdam�d. Dec. 7, 1709,  Amsterdam) Dutch landscape painter. He worked principally in Amster�  dam, painting quiet rural scenes studded with trees, rustic buildings,  peaceful streams, and water mills. His idyllic landscapes are carefully  composed and feature meticulous renderings of twisted foliage and gentle  terrain. In 1689 he produced his masterpiece. The Avenue, Middelharnis.  Though he apparently had little success in his lifetime, his work became  popular and influential in England in the 19th century. In the 20th cen�  tury he was generally regarded as second only to Jacob van Ruisdael, a  pupil of his, among Dutch landscapists.</p><p>Hobbes Vhabz\, Thomas (b.

The son of  a vicar who abandoned his family,</p><p>Hobbes was raised by his uncle.</p><p>After graduating from the University  of Oxford he became a tutor and  traveled with his pupil in Europe,  where he engaged Galileo in philo�  sophical discussions on the nature of  motion. He later turned to political  theory, but his support for absolutism  put him at odds with the rising anti�  royalist sentiment of the time. He  fled to Paris in 1640, where he  tutored the future King Charles II of  England. In Paris he wrote his best-  known work, Leviathan (1651), in  which he attempted to justify the  absolute power of the sovereign on  the basis of a hypothetical social  contract in which individuals seek to  protect themselves from one another  by agreeing to obey the sovereign in all matters. Hobbes returned to Brit�  ain in 1651 after the death of Charles I. In 1666 Parliament threatened to  investigate him as an atheist. His works are considered important state�  ments of the nascent ideas of liberalism as well as of the longstanding  assumptions of absolutism characteristic of the times.</p><p>Hobby, Oveta Culp orig. Oveta Culp (b. Jan. 19, 1905, Killeen,  Texas, U.S.�d. Aug. 16, 1995, Houston, Texas) U.S. publisher and gov�  ernment official. A graduate of the University of Texas Law School, she  was parliamentarian of the Texas legislature from 1925 to 1931. In 1931  she married William P. Hobby, publisher of the Houston Post-Dispatch ,  and went to work for the newspaper, becoming its executive vice presi�  dent in 1938. From 1942 to 1945 she headed the Women�s Auxiliary Army  Corps (later Women's Army Corps). In 1953 she was appointed director of  the Federal Security Agency, which was reorganized as the Department  of Health, Education, and Welfare; as secretary of the department (1953�  55), she was only the second woman to hold a U.S. cabinet position.

He sought to correlate  social change with its contribution to the general advance of the commu�  nity, focusing especially on the intellectual, moral, and religious elements  of change. He joined the staff of the Manchester Guardian (1897) and  continued to write for the newspaper after leaving to teach sociology at  the London School of Economics (1904-29). Among his works are Mor�  als in Evolution (1906), The Rational Good (1921), and Elements of Social  Justice (1922).</p><p>Hockney, David (b. July 9, 1937, Bradford, Eng.) British painter,  draftsman, printmaker, photographer, and stage designer. He studied at  the Bradford College of Art and the Royal College of Art in London. In  the mid 1960s he taught at the Universities of Iowa, Colorado, and Cali�  fornia, and in 1978 he settled permanently in Los Angeles. His portraits,  self-portraits, still lifes, and quiet scenes of friends are characterized by  economy of technique, preoccupation with light, bright colours, and a  frank, mundane realism derived from Pop art and photography. The Cali�  fornia swimming pool became one of his favourite themes. A brilliant  draftsman and printmaker, he published series of etchings, including illus�  trations for Six Fairy Tales of the Brothers Grimm (1969). In the 1970s  he achieved prominence as a set designer for the opera and ballet. He  later experimented with photography and photocollage, and still later with  computer technology and printers.</p><p>Hodges, Johnny orig. John Cornelius Hodges (b.

U.S. saxo�  phonist, one of the greatest alto-saxophone stylists in jazz. �Rabbit�  Hodges was encouraged and influenced by Sidney Bechet in the mid-1920s.  He joined Duke Ellington�s band in 1928 and quickly became its most  prominent soloist. Except for a period when he led his own small group  (1951-55), Hodges would remain with Ellington for the rest of his career.  His peerless, soulful tone and rhythmic poise made him a master inter�  preter of both ballads and blues, and Ellington and Billy Strayhorn com�  posed many pieces expressly for him.</p><p>Hodgkin, Dorothy M(ary) orig. Dorothy Mary Crowfoot (b.</p><p>May 12, 1910, Cairo, Egypt�d. July 29, 1994, Shipston-on-Stour, War�  wickshire, Eng.) English chemist. After studying at Oxford and Cam�  bridge, she went to work at Oxford. From 1942 to 1949 she worked on a  structural analysis of penicillin. In 1948 she and her colleagues made the  first X-ray photograph of vitamin B 12 , one of the most complex nonpro�  tein compounds, and they eventually completely determined its atomic  arrangement. In 1969 she completed a similar three-dimensional analysis  of insulin. Her work won her a 1964 Nobel Prize. She was chancellor of  Bristol University (1970-88) and was known for her work for peace and  international scientific cooperation. In 1965 she became the second  woman ever awarded the Order of Merit.</p><p>Hodgkin disease or lymphoreticuloma Uim-fo-ri-.tik-yo-  'lo-m9\ Most common malignant lymphoma. It starts with local, painless  swelling of lymph nodes and sometimes of the spleen, liver, or other  organs, followed by weight loss and weakness. Diagnosis can be con�  firmed only by biopsy, usually from a lymph node. The cause remains  unknown. Treatment with chemotherapy, radiation, or both depends on  the stage of the disease.

Robert immigrated to the U.S. in 1803.  In New York City he cofounded a printing-equipment company and in  1827 introduced the cast-iron frame, which soon replaced the standard  wooden frames used for printing presses. His improved version of the  Napier cylinder printing press supplanted all English-made presses in the  U.S. Richard joined the company in 1827 and became its head when his  father died. He replaced the flatbed press with the first successful rotary  press (patented 1847). He followed this innovation with the web press  (1865) and the web perfecting press (1871), revolutionary improvements  that made the large-circulation daily newspaper possible.</p><p>Hoff \hof. Jacobus H(enricus) van't (b. Aug. 30, 1852, Rotter�  dam, Neth.�d. March 1, 1911, Berlin, Ger.) Dutch physical chemist. His  early work on stereochemistry explained optical activity in terms of the  tetrahedral bonding of carbon atoms in organic molecules (see configura�  tion). His later work outlined the principles of chemical kinetics, applied  the laws of thermodynamics to chemical equilibria, introduced modern  concepts of chemical affinity, and advanced understanding of electrolytes.  Equations relating osmotic pressure (see osmosis) to mole fraction of sol�  ute and relating the equilibrium constant to temperature bear his name.  In 1901 he was awarded the first Nobel Prize for Chemistry.</p><p>Hoffa, Jimmy orig. James Riddle Hoffa (b.

He moved with his family to Detroit in 1924,  left school at 14, and began work as a stockboy and warehouseman. He  became a labour organizer in the 1930s, rising in the Teamsters Union dur�  ing the next two decades until he reached the office of president, which  he held from 1957 to 1971. Known throughout the trucking industry as a  tough bargainer, he played a key role in forging the first national freight-  hauling agreement and helped make the Teamsters the largest labour union  in the U.S. Long associated with underworld figures, he was sent to prison  in 1967 for jury tampering, fraud, and conspiracy; his sentence was com�  muted by Pres. Richard Nixon in 1971. In 1975 he disappeared from a  restaurant near Detroit; he is believed to have been murdered to prevent  his retaking control of the union. His son, James Riddle Hoffa, Jr. (b.  1941), was elected president of the Teamsters in 1999.</p><p>Hoffman, Abbie orig. Abbott Hoffman (b. Nov. 30, 1936,  Worcester, Mass., U.S.�d. April 12, 1989, New Hope, Pa.) U.S. politi�  cal activist. He attended Brandeis University and the University of Cali�  fornia, Berkeley, and became active in the civil rights movement. In 1968  he organized the Youth International Party (Yippies), which protested the  Vietnam War and the U.S. political and economic system. He gained wide�  spread media attention for his courtroom antics as a defendant in the  so-called Chicago Seven trial (1969), in which he was convicted of cross�  ing state lines with intent to riot at the Democratic Party�s national con�  vention in Chicago in 1968; the conviction was later overturned. After he  was arrested on charges of selling cocaine (1973), he went underground,  undergoing plastic surgery and adopting the alias �Barry Freed� to work  as an environmentalist in New York state. He resurfaced in 1980 and  served a year in prison before resuming his environmental work. His  books include Revolution for the Hell of It (1968), Steal This Book (1971),  and an autobiography, Soon to Be a Major Motion Picture (1980).</p><p>Hoffman, Dustin (b.

He played a remarkable  range of characters in films such as Midnight Cowboy (1969), Little Big  Man (1970), All the President�s Men (1976), Kramer vs. Kramer (1979,  Academy Award), Tootsie (1982), Rain Man (1988, Academy Award), and  Wag the Dog (1997). He returned to the Broadway stage in a revival of  Death of a Salesman (1984), repeating the role for television (1985,  Emmy Award), and played Shy lock in The Merchant of Venice in Lon�  don (1989) and New York (1990).</p><p>Hoffman, Samuel (Kurtz) (b.

At North American Aviation (1949-70),  he vastly increased the power of rocket engines, and he completed the  prototype of the engine for the launch vehicles that orbited the first U.S.  satellite (Explorer 1) and placed the first U.S. astronauts in space. His work  was essential to the early development of intercontinental and  intermediate-range ballistic missiles (see ICBM). From 1958 he oversaw  development of the engines for Saturn launch vehicles, which eventually  carried U.S. astronauts to the Moon.</p><p>Hoffmann Vh6f-man\, E(rnst) T(heodor) A(madeus) orig.

He initially supported himself as a  legal official (the conflict between the ideal world of art and daily bureau�  cratic life is evident in many of his stories) and later turned to writing and  music, which he often pursued simultaneously. His story collection Fan�  tasy Pieces in the Style of Callot (1814-15) established his reputation as  a writer. His later popular collections Hoffmann�s Strange Stories (1817)  and The Serapion Brethren (1819-21) combine wild flights of imagina-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Hoffmann &#x25BA; HoheTauern I 883</p><p>tion with vivid examinations of human character.

He cofounded, and  for 30 years (1903-33) directed, the Wiener Werkstatte (Vienna Work�  shop), an important centre for arts and crafts. Stoclet House (1905) in  Brussels is considered his masterpiece; the exterior of this opulent struc�  ture achieved an elegance not often associated with design based on  straight lines and white squares and rectangles. He designed the Austrian  pavilions for the 1914 Deutscher Werkbund Exhibition in Cologne and  for the 1934 Venice Biennale. In 1920 he was appointed city architect of  Vienna.</p><p>Hofmann, Hans (b. March 21, 1880, Weissenberg, Ger.�d. Feb. 17,  1966, New York, N.Y., U.S.)</p><p>German-born U.S. painter and art  teacher. From 1898 he studied art in  Munich, and in 1904 he moved to  Paris, where he was inspired by the  work of Henri Matisse and Robert  Delaunay.

Born into an aristocratic banking family, he made  his reputation with lyric poems (the first published when he was 16) and  verse plays, including The Death of Titian (1892) and Death and the Fool  (1893). He renounced lyrical poetry in a 1902 essay and thereafter turned  to theatre; his later plays include Christina's Journey Home (1910),  Everyman (1911), The Difficult Man (1921), and The Tower (1925). In  1906 he began a celebrated collaboration with the composer Richard  Strauss; their remarkable first opera, Elektra (1908), was followed by Der  Rosenkavalier (1910), Ariadne auf Naxos (1912, revised 1916), Die Frau  ohne Schatten (1919), and others. In 1920 he cofounded the Salzburg  Festival with Max Reinhardt.</p><p>hog Heavy, fat-producing domesticated pig developed in the U.S. in the  late 19th and early 20th century. As the growing use of cheaper vegetable  oils decreased the importance of lard as a source of fat, meatpackers  sought hogs yielding more lean meat and less fat, and breeders (mostly  European) began crossbreeding programs to obtain lean meat and vigor�  ous animals.

The  pig moves reluctantly and staggers; later it cannot rise; coma follows.  Antiserum is rarely effective. Survivors become chronically ill and can</p><p>spread the virus. Illness must be reported, infected animals slaughtered,  and quarantine instituted. A vaccine can control it.

Oct. 26, 1764,  London) British painter and  engraver. Apprenticed at 15 to a sil�  versmith, he opened his own engrav�  ing and printing shop at 22. He took  private drawing lessons while earn�  ing a living as an engraver of book  illustrations. His first major work,  the satirical engraving Masquerades  and Operas, attacked contemporary  taste and questioned the art estab�  lishment, thus winning him many  enemies. In 1728 he embarked on a  painting career with a work that  reveals his interest in theatre and  comic subject matter, A Scene from  �The Beggar's Opera�', he also  painted �conversation pieces� (infor�  mal group portraits) for wealthy cli�  ents. His engravings of modem  morality subjects, often in sequential  sets, were aimed at a wide public,  and their outstanding success estab�  lished his financial independence. To  safeguard his livelihood against  pirated editions, he fought for legislation protecting artists� copyright.  Britain�s first copyright act was passed in 1735, the year he published his  satirical eight-part series The Rake�s Progress. His other satirical series  include A Harlot�s Progress (1730-31) and Marriage a la Mode (1743�  45).

The talents of �the Ettrick Shepherd� were discov�  ered by Walter Scott when Hogg supplied material for Scott�s Minstrelsy  of the Scottish Border, and his popularity accompanied the ballad revival  of the early Romantic movement. Hogg�s other writings include the poetry  collection The Queen�s Wake (1813) and The Private Memoirs and Con�  fessions of a Justified Sinner (1824), a novel about religious mania with  a psychopathic hero that anticipates the modern psychological thriller.</p><p>Hoggar Mountains See Ahaggar</p><p>hognose snake Any of three or four species (genus Heterodon, fam�  ily Colubridae) of harmless North American snakes named for their  upturned snout, which is used for digging.

Active in  Bavarian politics from 1846, he served as minister president (1866-70)  after Prussia�s defeat of Bavaria in the Seven Weeks' War. He favoured a  unified Germany, and in 1871 he entered the service of the German  Empire. He was appointed German chancellor in 1894. His wide expe�  rience and fatherly relationship with Emperor William II failed to prevent  his sovereign�s demagogic excesses, and his influence largely ended in  1897 when Bernhard, prince von Bulow, became foreign secretary.</p><p>Hohenstaufen dynasty V.ho-on-'shtau-fonN German dynasty that  ruled the Holy Roman Empire (1138-1208, 1212-54). It was founded by  Count Frederick (died 1105), who built Staufen Castle and was appointed  duke of Swabia as Frederick I (1079). Hohenstaufen emperors included  Frederick I Barbarossa (r. 1155-90), Henry VI (r. 1191-97), and Frederick II  (r. 1220-50).

The first recorded  ancestor, Burchard I, was count of Zollern in the 11th century. Two main  branches were formed: the Franconian line (including burgraves of Niirn-  berg, electors of Brandenburg, kings of Prussia, and German emperors)  and the Swabian line (including counts of Zollern, princes of  Hohenzollem-Sigmaringen, and princes and then kings of Romania). The  Franconian branch became Lutheran at the Reformation but turned to Cal�  vinism in 1613 and acquired considerable territory in the 15th�17th cen�  turies. Both Prussian and German sovereignties were lost at the end of  World War I (1914-18). The Swabian line remained Catholic at the Ref�  ormation and ruled in Romania until 1947.

The Hohokam Indians  developed intricate networks of canals for irrigation, an agricultural engi�  neering feat unsurpassed in pre-Columbian North America. Some 14th-  century canals have been restored for use. Corn was the major crop; beans  and squash were added after contact with the Anasazi. For unknown rea�  sons, Hohokam culture disintegrated in the early 15th century. The Pima  and Papago peoples are probably direct descendants.</p><p>Hojo family Family of hereditary regents to the shogunate of Japan  who exercised actual power from 1199 to 1333. Hojo Tokimasa (1138�  1215) joined the cause of Minamoto Yoritomo against Taira Kiyomori, then  ruler of Japan. Together they prevailed, and Yoritomo became Japan�s new  ruler, taking the title of shogun. Tokimasa� s daughter married Yoritomo,  and when Yoritomo died in 1199 Tokimasa became regent to Yoritomo�s  heir, his own grandson. The position of shogunal regent became heredi�  tary; this office oversaw the constables and tax collectors that the shogu�  nate placed in each province. The system worked well through the first  half of the 13th century; its decline came about after resources had been  depleted defending Japan against two Mongol invasions and because of  the personal failings of the last Hojo regent. Hojo rule ended when Ash-  ikaga Takauji captured Kyoto in the name of the emperor Go-Daigo and  the Ashikaga family assumed the title of shogun.

Katsushika Hokusai (b. Oct. 1760, Edo,  Japan�d. May 10, 1849, Edo) Japanese painter, draftsman, printmaker,  and book illustrator. Apprenticed to a woodcut engraver at 15, he became  a student of the leading ukiyo-e master, Katsukawa Shunsho, in 1778. His  first published works, prints of kabuki actors, appeared the following year.  He soon turned to historical and landscape subjects and prints of children.  He developed an eclectic style and achieved success with book illustra�  tions and surimono prints (�printed things� for special occasions, such as  cards and announcements), picture books and novelettes, erotic books and  album prints, paintings, and ink sketches. He experimented with Western-  style perspective and use of colour and later concentrated on samurai  themes and Chinese subjects. His Thirty-six Views of Mount Fuji (1826�  33), a series of prints, marked a summit in the history of the Japanese  landscape print; in grandeur of concept and skill of execution there was  little approaching it before and nothing to surpass it later. He had numer�  ous followers, though none had his power or versatility.</p><p>Holbein \'hol- 1 bIn\, Hans, the Younger (b. 1497/98, Augsburg,  Bishopric of Augsburg�d. 1543, London, Eng.) German painter, drafts�  man, and designer renowned for the precise rendering of his drawings  and the compelling realism of his portraits, particularly those recording  the court of Henry VIII of England. His father, Hans Holbein the Elder,  and his uncle Sigmund were renowned for their somewhat conservative  examples of late Gothic painting in Germany. Holbein the Younger no  doubt studied with his father in Augsburg. He moved to Basel c. 1515,  entered the painters� corporation in 1519, and was executing important  murals by 1521. He also designed book illustrations and woodcuts for  publishers, notably a series of more than 40 scenes illustrating the medi�  eval allegory of the �dance of death� (1523-26). His portraits, including  that of Desiderius Erasmus (1523), featured rich colour, psychological  depth, detailed accessories, and dramatic silhouette. In 1526 he went to  England, where he painted portraits of German merchants and court per�  sonalities, and by 1536 he had entered the service of Henry VIII. In his  last 10 years he produced some 150 life-size and miniature portraits of  the royalty and nobility. He also designed fashions for the court and state  robes for the king. He was one of the greatest portraitists of all time.</p><p>Holberg \'hol-berg\, Ludvig, Baron (b. Dec. 3, 1684, Bergen,  Nor.�d. Jan. 28, 1754, Copenhagen, Den.) Norwegian-Danish man of  letters. Educated in Denmark and England, he traveled in various Euro�  pean countries before becoming a professor at the University of Copen�  hagen; while there he began to create a new class of humorous literature.  His seriocomic epic Peder Paars (1719), a parody of Virgil�s Aeneid, is  the earliest classic of the Danish language. Holberg was soon producing  a steady flow of stage comedies, including The Political Tinker (1723),  The Weathercock (1723), Jean de France (1723), Jeppe of the Hill (1723),  The Fussy Man (1731), and Erasmus Montanus (1731), many of which  are still produced. The outstanding Scandinavian literary figure of the  Enlightenment, Holberg is claimed by both Norway and Denmark as a  founder of their literatures.</p><p>Holderlin Vhcel-dor-.lenV (Johann Christian) Friedrich (b. March  20, 1770, Lauffen am Neckar, Wiirttemberg�d. June 7, 1843, Tubingen)  German poet. He qualified for ordination but found himself more drawn  to Greek mythology than to Christian dogma. In 1793 he was befriended  by Friedrich Schiller, who helped him publish his early poetry. He produced  works of passionate, expressive intensity, including his only novel, Hype-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>holding company &#x25BA; Hollerith I 885</p><p>rion (1797-99), the unfinished trag�  edy The Death of Empedocles, and a  number of odes, elegies, and verse  translations. In these works he natu�  ralized the forms of Classical Greek  verse in German and lamented the  loss of an idealized Classical Greek  world. His behaviour became erratic,  and in 1805 he succumbed irretriev�  ably to schizophrenia; he spent his  last 36 years in a carpenter�s house  under the shadow of insanity. Little  recognized in his lifetime, he was  forgotten until the 20th century,  when he came to be ranked among  the finest of German lyric poets.</p><p>holding company Corporation  that owns enough voting stock in one  or more other companies to exercise  control over them. A holding com�  pany provides a means of concen�  trating control of several companies  with a minimum of investment; other  means of gaining control, such as  mergers or consolidations, are more  complicated legally and more expensive. A holding company can reap the  benefits of a subsidiary�s goodwill and reputation while limiting its liabil�  ity to the proportion of the subsidiary�s stock that it owns. The parent  company in a conglomerate corporation is usually a holding company.</p><p>Holi Vho-le\ Hindu spring festival. It is held on the full-moon day of  Phalguna (February-March) and celebrated with reckless abandon. All  distinctions of caste, age, sex, and status are disregarded. Participants  throw coloured powders on each other, and street celebrations are noisy  and riotous. The festival is especially associated with the worship of  Krishna, and it is considered an imitation of his play with the wives and  daughters of the cowherds.</p><p>Holiday, Billie orig. Eleanora Fagan (b. April 7, 1915, Baltimore,  Md., U.S.�d. July 17, 1959, New  York, N.Y.) U.S. jazz singer. She was  �discovered� while she was singing  in a Harlem nightclub in 1933.</p><p>Recordings with Benny Goodman  and Duke Ellington led to a series of  outstanding small-group records  (1935�42) featuring musicians such  as Lester Young (who gave her the  sobriquet Lady Day) and Teddy Wil�  son. Exposure with the big bands of  Count Basie (1937) and Artie Shaw  (1938) brought her greater public  attention; for the rest of her life she  would remain one of the best known  of jazz singers. Among the songs  identified with her were �Strange  Fruit� and �God Bless the Child.� Personal crises and drug and alcohol  addiction plagued her career, and she was incarcerated in 1947 on nar�  cotics charges. Her voice could reveal a sweet, often sensual expressive�  ness or disturbing bitterness in the service of a lyric: her clear projection  of emotion represents a landmark of personal expression.</p><p>Holiness movement Fundamentalist religious movement that arose  in the 19th century among Protestant churches in the U.S. It was charac�  terized by the doctrine of sanctification, according to which believers were  enabled to live a perfect life after a conversion experience. It originated  in the teachings of John Wesley, founder of Methodism, who issued a call  for Christian �perfection� (the transformation of a sinner into a saint  through God�s intercession). In 1843 a group of Holiness ministers  founded the Wesleyan Methodist Church of America, which became  popular in the rural Midwest and South; another Holiness church of this  era was the Free Methodist Church of North America, founded in 1860.  Between 1880 and World War I a new set of Holiness groups appeared,  including the Church of the Nazarene, established to minister to the urban  poor, and the Church of God.</p><p>Holinshed \'ha-bn-,shed\, Raphael (d. c. 1580) English chronicler.  From c. 1560 Holinshed lived in London, where he was employed as a  translator by Reginald Wolfe, who was preparing a universal history.  Holinshed is remembered for his Chronicles of England, Scotlande, and  Irelande (1577), an abridged history he published after Wolfe�s death,  compiled largely uncritically from many sources of varying degrees of  trustworthiness. It enjoyed great popularity and was quarried by Elizabe�  than dramatists, especially William Shakespeare, who drew on its second  edition (1587) for Macbeth, King Lear, Cymbeline, and many of his his�  torical plays.</p><p>holism Vho-.li-zomX In the philosophy of the social sciences, the view  that denies that all large-scale social events and conditions are ultimately  explicable in terms of the individuals who participated in, enjoyed, or  suffered them. Methodological holism maintains that at least some social  phenomena must be studied at their own autonomous, macroscopic level  of analysis, that at least some social �wholes� are not reducible to or  completely explicable in terms of individuals� behaviour (see emergence).  Semantic holism denies the claim that all meaningful statements about  large-scale social phenomena (e.g., �The industrial revolution resulted in  urbanization�) can be translated without residue into statements about the  actions, attitudes, relations, and circumstances of individuals.</p><p>holistic \ho-'lis-tik\ medicine Doctrine of prevention and treatment  that emphasizes looking at the whole person�body, mind, emotions, and  environment�rather than a single function or organ. It promotes use of  a wide range of health practices and therapies, including acupuncture,  homeopathy, and nutrition, stressing �self-care� with traditional common-  sense essentials. In the extreme, it may accord equal validity to a wide  range of health-care approaches, some incompatible and not all scientific.  It does not ignore mainstream Western medical practices but does not see  them as the only effective therapies.

It originated in the early 12th century as  a fief of the Holy Roman Empire. In 1299 Holland was united with Hain-  aut. Members of the house of Wittelsbach served as counts of Holland,  Zeeland, and Hainaut until 1433, when they ceded the titles to Philip III  (the Good), duke of Burgundy. It passed to the Habsburgs in 1482 and  became a centre of the revolt against Spain in 1572. Holland and six other  northern Netherlands provinces declared their independence from Spain  in 1579, proclaiming the United Provinces of the Netherlands. Its capi�  tal, Amsterdam, became Europe�s foremost commercial centre in the 18th  century. The Napoleonic kingdom of Holland occupied the territory  (1806-10). In 1840 it was divided into the provinces of North Holland  and South Holland.</p><p>Holland, Brian and Eddie orig. Edward Holland (respectively  b. Feb. 15, 1941, Detroit, Mich., U.S.; b.

In 1962 the brothers formed a team  with Lamont Dozier (b. 1941), which subsequently created a series of hits  for almost every artist on the Motown label and helped define its char�  acteristic sound through blending elements of gospel music and rhythm and  blues with elaborate arrangements. Their songs include �Baby Love,�  �Stop! In the Name of Love� (two of the seven hits they wrote for the  Supremes), �Heat Wave,� �Baby, I Need Your Loving,� and dozens of other  hits for artists such as Marvin Gaye and the Temptations.</p><p>Holland (of Foxley and of Holland), Henry Richard Vas-  sall Fox, 3rd Baron (b.

As lord privy seal in George Grenville�s �Ministry of  All the Talents� coalition (1806-07), he helped secure the abolition of the  slave trade in the British colonies. He later served as chancellor of the  duchy of Lancaster (1830-34, 1835-40).</p><p>Hollerith, Herman (b. Feb. 29, 1860, Buffalo, N.Y., U.S.�d. Nov.  17, 1929, Washington, D.C.) U.S. inventor. He attended Columbia Uni�  versity�s School of Mines and later assisted in the 1880 U.S. census. By  the time of the 1890 census, he had invented machines to record statis�  tics by electrically reading and sorting punched cards, and the census  results were consequently obtained in one-third the time required in 1880.  In 1896 he founded the Tabulating Machine Co., which later became IBM  Corp.

Holley and others showed that transfer RNA was  involved in the assembly of amino acids into proteins. He was the first to  determine the sequence of nucleotides in a nucleic acid, a process that  required digesting the molecule with enzymes, identifying the pieces, and  then figuring out how they fit together. It has since been shown that all  transfer RNA has a similar structure. He shared a 1968 Nobel Prize with  Marshall Warren Nirenberg and Har Gobind Khorana.</p><p>Holliday, Doc orig.

After graduating from dental school in 1872, he  moved to the drier climate of the West to help treat his tuberculosis. After  practicing dentistry briefly in Dallas, Texas, he took up gambling, and he  began drifting throughout the West, finally settling in Tombstone, Ariz.,  in 1880. There he joined Wyatt Earp and his brothers in the famous gun-  fight at the O.K. Corral (1881). Having earned a reputation as a gunman,  he resumed his drifting; five years later he died of tuberculosis at age 35.</p><p>Hollweg, Theobald von Bethmann See Theobald von Bethmann  Hollweg</p><p>holly Any of approximately 400 species of red- or black-berried orna�  mental shrubs and trees that make up  the genus Ilex (family Aquifoli-  aceae), including the popular Christ�  mas hollies.

He prac�  ticed law in Boston from 1867, eventually serving as an associate justice  (1882-99) and then chief justice (1899-1902) of the state supreme court.  In The Common Law (1881), he advanced the notion of law as accumu�  lated experience rather than science. Appointed to the Supreme Court of  the United States by Pres. Theodore Roosevelt in 1902, Holmes advocated  judicial restraint, maintaining that lawmaking was the business of legis�  lative bodies rather than the courts. In Schenk v.

Under the  Nurnberg Laws (1935), Jews lost their citizenship. About 7,500 Jewish  businesses were gutted and some 1,000 synagogues burned or damaged  in the Kristallnacht pogrom in 1938, and thereafter Jews were imprisoned  in concentration camps or forced into ghettos. German victories early in  World War II (1939�45) brought most European Jews under the control  of the Nazis and their satellites. As German armies moved into Poland,  the Balkans, and the Soviet Union, special mobile killing units, the Ein-  satzgruppen, rounded up and killed Jews, Roma (Gypsies), communists,  political leaders, and intellectuals. Other groups targeted by the Nazis  included homosexuals and the mentally retarded, physically disabled, and  emotionally disturbed. At the Wannsee Conference (1942), a �final solu�  tion� was formulated for the extermination of European Jewry, and there�  after Jews from all over Nazi-occupied Europe were systematically  evacuated to concentration and extermination camps, where they were  either killed or forced into slave labour. Underground resistance move�  ments arose in several countries, and Jewish risings took place against  overwhelming odds in the ghettos of Poland (see Warsaw Ghetto Upris�  ing). Individuals such as Raoul Wallenberg saved thousands by their  efforts; whether the Allied governments and the Vatican could have done  more to aid Jews has long been a matter of controversy. By the end of  the war, an estimated six million Jews and millions of others had been  killed by Nazi Germany and its collaborators.</p><p>Holocaust Remembrance days International commemoration of  the millions of victims of Nazi Germany�s exterminationist policies. The  commemoration, observed on different days in different countries, often  marks the victims� efforts at resistance and concentrates on contemporary  efforts to battle hatred and anti-Semitism. From 1951 Jews have observed  Holocaust Remembrance Day on the 27th of Nisan, shortly after Pass-  over, in the Jewish calendar. The Israeli parliament declared that day Yom  Hashoah ve Hagevurah (Holocaust Remembrance and Heroism Day),  marking not only destruction but resistance.</p><p>Holocene Vho-l3-,sen\ Epoch formerly Recent Epoch Latest inter�  val of the Earth�s geologic history, dating from 10,000 years ago to the  present.

To create a hologram, a beam of coher�  ent light (a laser) is split; half the beam falls on a recording medium (such  as a photographic plate) unaltered, and the other half is first reflected off  the object to be imaged. The two beams together produce an interference  pattern of stripes and whorls on the plate. The developed plate is the holo�  gram. When light is shone on the hologram, a three-dimensional image  of the original object is produced by the recorded interference pattern.  Some holograms require laser light to reproduce the image; others may  be viewed in ordinary white light. Holography was invented in 1947 by  the Hungarian-British physicist Dennis Gabor (1900-1979), who won a  1971 Nobel Prize for his invention.</p><p>Holst, Gustav(us Theodore von) (b.

After Bismarck�s dismissal in 1890, Holstein advised  against the renewal of the Reinsurance Treaty.

To put an end to the league,  which challenged his authority, Henry III had the duke de Guise assassi�  nated (1588), an act that, rather than destroying the League, led to Henry�s  own assassination in 1589.

Traditionally believed to have been established by Charlemagne, who was  crowned emperor by Pope Leo III in 800, the empire lasted until the  renunciation of the imperial title by Francis II in 1806. The reign of the  German Otto I (the Great; r. 962-973), who revived the imperial title after  Carolingian decline, is also sometimes regarded as the beginning of the  empire. The name Holy Roman Empire (not adopted until the reign of  Frederick I Barbarossa) reflected Charlemagne�s claim that his empire was  the successor to the Roman Empire and that this temporal power was  augmented by his status as God�s principal vicar in the temporal realm  (parallel to the pope�s in the spiritual realm). The empire�s core consisted  of Germany, Austria, Bohemia, and Moravia. Switzerland, the Nether�  lands, and northern Italy sometimes formed part of it; France, Poland,  Hungary, and Denmark were initially included, and Britain and Spain  were nominal components. From the mid-11th century the emperors  engaged in a great struggle with the papacy for dominance, and, particu�  larly under the powerful Hohenstaufen dynasty (1138-1208, 1212-54),  they fought with the popes over control of Italy. Rudolf I became the first  Habsburg emperor in 1273, and from 1438 the Habsburg dynasty held the  throne for centuries. Until 1356 the emperor was chosen by the German  princes; thereafter he was formally elected by the electors. Outside their  personal hereditary domains, emperors shared power with the imperial  diet. During the Reformation the German princes largely defected to the  Protestant camp, opposing the Catholic emperor. At the end of the Thirty  Years' War, the Peace of Westphalia (1648) recognized the individual sov�  ereignty of the empire�s states; the empire thereafter became a loose fed�  eration of states and the title of emperor principally honorific. In the 18th  century, issues of imperial succession resulted in the War of the Austrian  Succession and the Seven Years' War. The greatly weakened empire was  brought to an end by the victories of Napoleon. See also Guelphs and Ghi-  bellines; Investiture Controversy; Concordat of Worms.

Though references to the spirit of Yahweh (God)  abound in the Old Testament, Christian teaching about the Holy Spirit is  derived mainly from the Gospels. The Holy Spirit descended on Jesus at  his baptism, and outpourings of the Spirit are mentioned in the Acts of  the Apostles, in which healing, prophecy, exorcism, and speaking in  tongues are associated with its activity. The Holy Spirit also came to the  disciples during Pentecost. The definition of the Holy Spirit as a divine  person equal in substance to the Father and the Son was made at the  Council of Constantinople (ad 381).</p><p>Holy Synod Ysi-nad\ Ecclesiastical governing body created by Tsar  Peter I in 1721 to head the Russian Orthodox Church, replacing the patri�  archate of Moscow. Peter created the Synod, made up of representatives  of the hierarchy obedient to his will, to subject the church to the state, and  appointed a secular official, the chief procurator, to supervise its activi�  ties. The Synod persecuted all dissenters and censored publications, and  Peter disposed of church property and revenues for state purposes at his  own discretion. In 1917 a church council reestablished the patriarchate,  but the new Soviet government soon nationalized all church-held lands.</p><p>holy war Any war fought by divine command or for a primarily reli�  gious purpose. The concept is found in the Bible (e.g., the Book of Joshua)</p><p>and has played a role in many religions. The Crusades are Europe�s best-  known example. In Islam, the concept is called jihad. Wars in which reli�  gion plays a secondary or exacerbating role are not generally called holy  wars.</p><p>Holyfield, Evander (b. Oct. 19, 1962, Atmore, Ala., U.S.) U.S. boxer.  Holyfield is the only boxer to win a version of the heavyweight cham�  pionship four separate times (Muhammad Au won the heavyweight cham�  pionship three times). Holyfield�s first title win was against James  �Buster� Douglas in 1990 and he won the unified title at that time. He  lost the title to Riddick Bowe in 1992, recaptured it in 1993, and lost it  to Michael Moorer in 1994. When he fought Mike Tyson in 1996, he  regained only the WBA (World Boxing Association) portion of the title.  In 1997 he won the IBF (International Boxing Federation) heavyweight  title from Moorer. In Holyfield�s title defense against Tyson in 1997,  Tyson was disqualified for biting Holyfield�s ear. Holyfield lost the IBF  and WBA titles to the WBC (World Boxing Council) heavyweight cham�  pion Lennox Lewis in 1999, but Lewis later was stripped of the WBA por�  tion of his title, and when Holyfield beat John Ruiz in the subsequent  WBA title bout in 2000, he became the first man to win a championship  in the heavyweight division for the fourth time.</p><p>Holzer Vholt-sarX, Jenny (b. July 29, 1950, Gallipolis, Ohio, U.S.) U.S.  conceptual artist. She studied at Duke University, the University of Chi�  cago, and the Rhode Island School of Design. In the late 1970s she became  involved with conceptual art and with artists known for their �word art,�  which involved the display of words and text instead of visual images.  In the late 1970s she began to display her �truisms,� slogans and brief  confrontational statements, usually containing political or social critique,  that she printed on posters and flyers and posted throughout Manhattan.  In the 1980s and �90s she displayed her messages on LED (light-emitting  diode) signs, the medium with which she is most associated, in venues  such as Times Square. Like most of her oeuvre, these works were meant  to confront the viewer and elicit debate or discussion.</p><p>Home, Alec Douglas- See Sir Alec Douglas-Home  home page See Web site</p><p>Home Rule, Irish Movement to secure internal autonomy for Ireland  within the British Empire. The slogan �Home Rule� was popularized in  1870 when the Home Government Association (later the Home Rule  League) called for an Irish parliament. It was led from 1878 by Charles  Stewart Parnell, whose obstructionist tactics in the British Parliament pub�  licized his country�s grievances. The Home Rule bills introduced by Prime  Minister William E. Gladstone in 1885 and 1893 were defeated. A third  bill became law in 1914 but was militantly opposed by Ulster unionists  and republicans in Ireland. A system akin to home rule was established  in the six counties of Ulster (Northern Ireland) in 1920. In 1921 the  remaining 26 counties in the south achieved dominion status, but the link  with the British Commonwealth was severed in 1949.</p><p>Homel See Homyel</p><p>homeopathy V.ho-me-'a-po-theV System of therapeutics founded in  1796 by Samuel Hahnemann on the principle that �like cures like.� That  is, substances that in healthy persons would produce the symptoms from  which the patient suffers are used to treat the patient. Hahnemann further  stated that the potency of a curative agent increases as the substance is  diluted. When it was introduced, homeopathy was a mild, welcome alter�  native to heavy-handed therapies such as bleeding, but it has since been  criticized for focusing on symptoms rather than causes. With the rise of  alternative medicine, it has seen a resurgence.</p><p>homeostasis X.ho-me-o-'sta-sosX Any self-regulating process by which  a biological or mechanical system maintains stability while adjusting to  changing conditions. Systems in dynamic equilibrium reach a balance in  which internal change continuously compensates for external change in  a feedback control process to keep conditions relatively uniform. An  example is temperature regulation�mechanically in a room by a thermo�  stat or biologically in the body by a complex system controlled by the  hypothalamus, which adjusts breathing and metabolic rates, blood-vessel  dilation, and blood-sugar level in response to changes caused by factors  including ambient temperature, hormones, and disease.</p><p>Homer (fl. 9th or 8th century bc, Ionia?) Greek poet, one of the great�  est and most influential writers of all time. Though almost nothing is  known of his life, tradition holds that he was blind. The ancient Greeks</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Homer &#x25BA; homology I 889</p><p>attributed to him the great epic poems The Iliad and The Odyssey. Mod�  em scholars generally agree that he composed (but probably did not lit�  erally write) The Iliad, most likely relying on oral traditions, and at least  inspired the composition of The Odyssey. The Iliad, set during the Trojan  War, tells the story of the wrath of Achilles; The Odyssey tells the story  of Odysseus as he travels home from the war. The two epics provided the  basis of Greek education and culture in the Classical age, and they have  remained among the most significant poems of the European tradition.</p><p>Homer, Winslow (b. Feb. 24, 1836, Boston, Mass., U.S.�d. Sept.  29, 1910, Prouts Neck, Maine) U.S. painter. He served an apprenticeship  with a Boston lithographer, then became a freelance illustrator in New  York City. He exhibited at the National Academy of Design in 1860 and  was elected a member in 1865. During a stay in France in 1866, he was  attracted to French naturalism and Japanese prints, but they had little  effect on his generally bright and happy work. He became a master of  watercolour and his ability as an oil painter matured; he focused increas�  ingly on solitary, withdrawn figures. He spent 1881-82 in the English vil�  lage of Tynemouth, on the North Sea, where the coastal atmosphere, the  sea, and the stoic people are the subjects of some of his most powerful  images. In 1883 he moved permanently to Prouts Neck, and his dominant  theme became the sea and the endless struggle against an uncaring nature.  In his later years he continued to paint vigorously and in near-total iso�  lation. Though he was recognized in his lifetime as a leading U.S. painter,  appreciation of his enormous achievement came only after his death.</p><p>Homestead Movement Mid-19th-century drive for free land in the  U.S. Midwest, Great Plains, and West. It began in the 1830s as labourers  and reformers joined farmers in calling for public land to be given free  to settlers. In 1848 the Free Soil Party advocated the homestead proposal.  Opposition from industrial employers and Southern slaveholders blocked  legislation until the 1860 election, when the winning Republican Party sup�  ported a homestead measure. In 1862 the Homestead Act was passed,  providing 160 acres of public land free to any adult citizen or head of  family who had lived on the land for five years. By 1900, 600,000 home�  steaders had claimed 80 million acres.</p><p>Homestead National Monument Memorial, southeastern  Nebraska, U.S. Established in 1936 as a memorial to the hardships of pio�  neer life, it is the site of the first claim under the Homestead Act of 1862  and has exhibits tracing the development of the Homestead Movement. It  occupies 163 acres (66 hectares) and includes a homestead log cabin.</p><p>Homestead Strike U.S. labour strike at Andrew Carnegie�s steelworks  in Homestead, Pa., in July 1892. When the Amalgamated Association of  Iron and Steel Workers went on strike following a wage cut, the compa�  ny�s manager, Henry Clay Frick, hired strikebreakers, with Pinkerton  Agency detectives to protect them. A gun battle resulted in which several  people were killed and many injured; the governor sent state militiamen  to support the company. The broken strike represented a major setback  to the union movement that was felt for decades.</p><p>homicide Killing of one human being by another. Homicide is a gen�  eral term; it includes murder, manslaughter, and other criminal homicides  as well as noncriminal killings. Murder is the crime of intentionally and  unjustifiably killing another. In the U.S., first-degree murder is a homi�  cide committed with premeditation or in the course of a serious felony  (e.g., kidnapping). Second- and third-degree murder involve lesser degrees  of intent. Manslaughter is commonly divided into voluntary (or first-  degree) and involuntary (or second- and third-degree) manslaughter. The  first type encompasses any homicide resulting from an intentional act  done without malice or premeditation and while in the heat of passion or  on sudden provocation; the second type is variously defined in different  jurisdictions but often includes an element of unlawful recklessness or  negligence. Noncriminal homicides include killings committed in defense  of oneself or another and deaths resulting from accidents caused by per�  sons engaged in lawful acts. See also felony and misdemeanour; self-defense.</p><p>hominid Vha-mo-.nidV Any member of the zoological family Hominidae  (order Primates), which consists of the great apes (orangutans, gorillas,  chimpanzees, and bonobos) as well as human beings. Formerly, only  humans (with their extinct forebears) were categorized as hominids, and  the great apes were categorized as pongids�that is, members of the pri�  mate family Pongidae. However, morphological and molecular studies  now indicate that humans are closely related to chimpanzees, while goril�  las are more distant and orangutans more distant still. As a result, it has</p><p>become more common among zoologists to consider humans and great  apes to be hominids. See also hominin.</p><p>hominin Vha-m3- l nin\ Any member of the zoological �tribe� Hominini  (family Hominidae, order Primates), of which only one species exists  today� Homo sapiens, or human beings. The term is used most often to  refer to extinct members of the human lineage, some of which are now  quite well known from fossil remains: Homo neanderthalensis (the Nean�  derthals), Homo erectus. Homo habilis, and various species of Australopith�  ecus. The primate group most closely related to Hominini today is  Gorillini (the African apes), comprising the gorilla, the chimpanzee, and  the bonobo. Gorillini and Hominini are part of the great ape family, Hom�  inidae. Some characteristics that have distinguished hominins from other  primates, living and extinct, are their erect posture, bipedal locomotion,  larger brains, and behavioral characteristics such as specialized tool use  and, in some cases, communication through language.</p><p>Homo Genus of the primate family Hominidae. Members of Homo are  characterized by a relatively large cranium (braincase), limb structure  adapted to erect posture and a two-footed gait, well-developed and fully  opposable thumbs, hands capable of power and precision grips, and the  ability to make precision tools. The genus includes modern humans  ( Homo sapiens), the extinct species Homo habilis. Homo erectus, and Homo  neanderthalensis (the Neanderthals), and the early form of H. sapiens  known as Cro-Magnon.</p><p>Homo erectus Latin "upright man" Extinct species of early hom�  inin, perhaps a direct ancestor of human beings ( Homo sapiens). Homo  erectus flourished from c. 1,700,000 to 200,000 years ago, ranging widely  from Africa (where the species probably originated) to Asia to parts of  Europe. Most of the anatomical differences between H. erectus and H.  sapiens concern the skull and teeth, H. erectus showing a low, thick  braincase (800-1,100 cc) with jutting browridges and a wide nose, pal�  ate, and jaw together with large teeth that are nevertheless hominin and  not apelike. The limb bones are similar to those of H. sapiens, indicating  that H. erectus was of medium stature and walked upright. The species is  associated with the Acheulean tool tradition and was the first hominin to  master fire and inhabit caves. See also human evolution; Java man; Zhouk-</p><p>OUDIAN.</p><p>Homo habilis V.ho-mo-'ha-bo-bsV Latin "handy man" Extinct spe�  cies of early hominin that is generally regarded as the earliest member of  the human genus, Homo. Homo habilis inhabited parts of sub-Saharan  Africa about 2-1.5 million years ago. Remains were first discovered in  1959 and 1960 at Olduvai Gorge in northern Tanzania; additional remains  have since been found in the Lake Turkana region of northern Kenya and,  arguably, at Sterkfontein in South Africa. The cranial capacity of H. habi�  lis ranged from 500 to 800 cc. Limb bones suggest that the species walked  upright efficiently, and the fossil of a hand suggests that H. habilis was  capable of precise manipulation of objects. Crude tools found along with  H. habilis remains provide further evidence that this species could shape  stone. See also human evolution; Oldowan industry.</p><p>Homo sapiens Latin "wise man" Species to which all modem  human beings belong. The oldest known fossil remains date to c. 120,000  years ago�or much earlier (c. 400,000 years ago) if evidence of certain  archaic varieties is included. Homo sapiens is distinguished from earlier  hominin species by characteristics and habits such as bipedal stance and  gait, brain capacity averaging about 1,350 cc, high forehead, small teeth  and jaw, defined chin, construction and use of tools, and ability to use  symbols. Most scholars believe that modern humans developed in Africa  c. 150,000 years ago and spread to the Middle East c. 100,000 years ago  and to other parts of Eurasia c. 40,000-50,000 years ago (this is known  as the �single-origin� model). Others contend that modern humans devel�  oped from various regional populations of archaic H. sapiens or even  other species of Homo in Eurasia beginning c. 250,000 years ago (the  �multiregional� model). In the first model the genetic differences that exist  between the peoples of the world would not be very old; in the second  model they would be significantly older. In any case, by c. 11,000 bc  modern H. sapiens had peopled virtually the entire globe.

Female homosexuality is frequently referred to as lesbianism; the  word gay is often used as an alternative for both �homosexual� and �les�  bian,� though it may refer specifically to male homosexuality. At differ�  ent times and in different cultures, homosexual behaviour has variously  been encouraged, approved of, tolerated, punished, and banned. Homo�  sexuality was not uncommon in ancient Greece and Rome, particularly  between adult and adolescent males. Jewish, Christian, and Muslim cul�  tures have generally viewed it as sinful, although many religious leaders  have said it is the act, and not the inclination, that their faiths proscribe.  Attitudes toward homosexuality are generally in flux, partly because of  increased political activism (see gay rights movement). Until the early  1970s many medical organizations, such as the American Psychiatric  Association, classified homosexuality as a mental illness, but that desig�  nation was widely dropped in subsequent years. Longstanding beliefs  about homosexuals (including the stereotype that gay men are weak and  effeminate and lesbians aggressive and masculine) have also largely  faded; some countries, cultures, and religious groups, however, continue  to view homosexuality as deviant. Homosexual orientation, like sexual�  ity in general, apparently results from a combination of hereditary factors  and social or environmental influences, and it tends to coexist with het�  erosexual feelings in varying degrees in different individuals.</p><p>homozygote and heterozygote Two genetic possibilities for a  fertilized egg. If the two sex cells (gametes) that fuse during fertilization  carry the same form of a gene for a specific trait, the organism is said to  be a homozygote for that trait. If the gametes carry differing forms of the  gene, the result is a heterozygote. Because genes may be either dominant  or recessive (see dominance and recessiveness), the genetic composition  (genotype) of an organism cannot always be determined by the organism�s  physical appearance (phenotype).</p><p>Homs See Hims</p><p>Homyel \ko-'myel\ Russian Homel \ho-'mel\ City (pop., 2001 est.:  490,000), capital of Homyel province, southeastern Belarus.

Honey has played  an important role in human nutrition since ancient times; until about 250  years ago, it was almost the sole sweetening agent. Honey is often pro�  duced on a commercial scale from clover ( Trifolium) or sweet clover  ( Melilotus ) by the domestic honeybee. The nectar is ripened into honey by  inversion of most of its sucrose into the sugars levulose (fructose) and  dextrose (glucose) and the removal of excess moisture. Honey is stored  in the beehive or nest in a honeycomb, a double layer of uniform hex�  agonal cells constructed of beeswax and propolis (a plant resin). The honey  is used in winter as food for the bee larvae and other members of the  colony. Honey extracted for human consumption is usually heated to  destroy fermentation-causing yeasts and then strained.

The term is usually  applied to one species, the domestic  honeybee (A. mellifera ), also known  as the European domestic bee or  western honeybee. The other Apis  species are confined to Asia. A. mel�  lifera is usually about 0.5 in. (1.2 cm)  long. All honeybees are social insects  that live in nests or hives.

In 1850  he began plotting a rebellion; the next year he declared himself Heavenly  King of the Heavenly Kingdom of Great Peace (Taiping Tianguo). His  army of more than a million men and women soldiers captured Nanjing,  which became Hong�s new capital.

In the  11th century, canals were constructed to make it part of a canal system  between Kaifeng and Zhuzhou, joining the lake to the Huai. In 1194 the  Huang He (Yellow River) changed course, forcing the waters of the Huai  into the lake, which then grew to its present size. In the 19th century,  flooding in the area was severe, and in the 1930s a new channel (improved  in the 1950s) was dug from the lake�s eastern shore directly to the sea.</p><p>Honiara \ l h6-ne- , ar-o\ Town (pop., 1999 est.: 49,107), capital of the  Solomon Islands, South Pacific Ocean.

Its area of 597 sq mi (1,545 sq  km) includes some outlying islets, which constitute the Hawaiian and  Pacific Islands National Wildlife Refuge. Honolulu has about 80% of the  state�s population. The area was settled from c. 1100, according to Hawai�  ian legends. During the 19th century Honolulu flourished as a trade cen�  tre, especially for whalers. In 1898 it passed with the rest of Hawaii to  U.S. control. In December 1941 the city and adjacent Pearl Harbor were  bombed by the Japanese.

During 10  years in Italy (c. 1610-20) he enjoyed the patronage of the nobility and  assimilated the Baroque style of Caravaggio. The dramatic effects of arti�  ficial light in his early paintings, as in such nocturnal scenes as Supper  Party (1620), earned him his nickname. He was court painter at The  Hague from 1637 to 1652. Some of Rembrandt�s early works were inspired  by his use of chiaroscuro.

In style and subject matter, his work is similar to that  of Johannes Vermeer; he was noted for his small interiors and sunny out�  door scenes, with figures engaged in humble, domestic activities in set�  tings of serene simplicity. In his best works, he was concerned with the  effect of enclosures on light intensity, tonal variations, and linear perspec�  tive. After he moved to Amsterdam (c. 1661), his paintings increased in  quantity but declined in quality.

His important law of elasticity, known as Hooke�s law (1660), states that  the stretching of a solid is proportional to the force applied to it. He was  one of the first to build and use a reflecting telescope. He suggested that  Jupiter rotates on its axis, and his detailed sketches of Mars were later  used to determine its rate of rotation. He suggested that a pendulum could  be used to measure gravitation, and he attempted to show that the Earth  and Moon follow an elliptical orbit around the Sun. He discovered dif�  fraction and proposed the wave theory of light to explain it. He was one  of the first proponents of the theory of evolution. He was the first to state  in general that all matter expands when heated and that air is made up of  particles separated from each other by relatively large distances. He  invented a marine barometer, contributed improvements to clocks, the  quadrant, and the universal joint, and anticipated the steam engine.</p><p>Hooker, Joseph (b.

After graduating from Stanford University (1895), he became a min�  ing engineer, administering engineering projects on four continents  (1895-1913). He then headed Allied relief operations in England and  Belgium. As U.S. national food administrator during World War I, he  instituted programs that furnished food to the Allies and to famine-  stricken areas of Europe. Appointed U.S. secretary of commerce (1921�  27), he reorganized the department, creating divisions to regulate  broadcasting and aviation. He oversaw commissions to build Boulder  (later Hoover) Dam and the St. Lawrence Seaway. In 1928, as the Repub�  lican presidential candidate, he soundly defeated Alfred E. Smith. His hopes  for a �New Day� program were quickly overwhelmed by the Great Depres�  sion. In response, he called business leaders to the White House to urge  them not to lay off workers or cut wages, and he urged state and local  governments to join private charities in caring for destitute Americans.  Believing that a dole would sap the will of Americans to provide for  themselves, he adamantly opposed direct federal relief payments to indi�  viduals, though in 1932 he finally allowed relief to farmers through the  Reconstruction Finance Corp. After his electoral defeat in 1932 by Fran�  klin D. Roosevelt, he regularly spoke out against what he considered the  radicalism of the New Deal and  Roosevelt�s attempts to involve the  U.S. in countering German and Japa�  nese aggression.

In the 1930s he successfully  publicized the FBI�s success in tracking down and capturing well-known  criminals. During this time, both the FBI�s size and its responsibilities  grew steadily. In the late 1930s Hoover received authorization to inves�  tigate foreign espionage in the U.S. and the activities of communists and  fascists alike. When the Cold War began in the late 1940s, the FBI under�  took intensive surveillance of communists and other left-wing activists in  the U.S. Hoover�s animus toward radicals of every kind led him to inves�  tigate both the Ku Klux Klan and Martin Luther King, Jr., as well as other  African American activists in the 1960s. At the same time, he maintained  a hands-off policy toward the Mafia, which was allowed to conduct its  operations nationwide practically free of FBI scrutiny or interference.  Hoover habitually used the FBI�s enormous surveillance and information�  gathering powers to collect damaging information on politicians through�  out the country, and apparently he was able to intimidate even sitting  presidents by threatening to leak damaging disclosures about them.

Most live on reservation lands in north�  eastern Arizona, U.S., surrounded by the Navajo Reservation. The name  Hopi means �Peaceful Ones.� They speak a language of the Uto-Aztecan  stock. Most of their traditional settlements were on high mesas and con�  sisted of terraced pueblo structures of stone and adobe. Their precise ori�  gin is unknown, though they are usually considered descendants of the  Anasazi peoples. Matrilineal descent was the rule. They supported them�  selves by growing corn, beans, squash, and melons and by sheepherding.  Hopi life was steeped in religious ceremony and involved secret rites held  in semi-underground kivas (pit-houses) and the use of masks and costumes  to impersonate kachinas (ancestral spirits). Some 11,100 people claimed  sole Hopi descent in the 2000 U.S. census.</p><p>Hopkins, Sir Anthony (b. Dec. 31, 1937, Port Talbot, West Gla�  morgan, Wales) British actor. He joined London�s National Theatre in  1965, where he starred in Shakespearean roles. A subtle actor able to con�  vey volcanic emotion with a small gesture, he made an acclaimed Broad�  way debut in Equus (1974). Hopkins stayed on in the U.S. for films such  as The Elephant Man (1980) and television productions such as The Bun�  ker (1981, Emmy Award). At the National Theatre he triumphed in King  Lear and Antony and Cleopatra. He won an Oscar for his chilling per�  formance as Hannibal Lecter in The Silence of the Lambs (1991), a role  he played in two sequels. He also starred in Howards End (1992), The  Remains of the Day (1993), and Amistad (1997).</p><p>Hopkins, Esek (b. April 26, 1718, Providence, R.I.�d. Feb. 26, 1802,  Providence, R.I., U.S.) American naval officer. He went to sea at age 20,  proving his ability as a seaman and a trader. A marriage into wealth put  him at the head of a large merchant fleet prior to the French and Indian  War (1754-63); his privateering during that conflict added to both his  fortune and his naval reputation. In 1775 he was appointed the first com�  mander of the Continental Navy. Instructed to attack the British fleet in  Chesapeake Bay, he sailed instead for the Bahamas, where he captured  the British post at New Providence. He returned to Rhode Island, where  the fleet became largely inactive. In 1776 an investigation by Congress  led to his censure for disobedience. The fleet�s continuing inactivity led  to his suspension from command (1777) and dismissal (1778).</p><p>Hopkins, Sir Frederick Gowland (b. June 20, 1861, Eastbourne,  East Sussex, Eng.�d. May 16, 1947, Cambridge, Cambridgeshire) Brit�  ish biochemist. He discovered the amino acid tryptophan (1901) and  showed that it and certain others are essential in the diet and cannot be  made in the body from other substances. For his discovery of vitamins, he  shared a 1929 Nobel Prize with Christiaan Eijkman. He demonstrated that  working muscles accumulate lactic acid and isolated the tripeptide (see  peptide) glutathione (1922) and showed that it is vital to utilization of oxy�  gen by cells. He was knighted in 1925.</p><p>Hopkins, Gerard Manley (b. July 28, 1844, Stratford, Essex,  Eng.�d. June 8, 1889, Dublin, Ire.) British poet. After studies at Oxford,  he converted to Roman Catholicism and eventually became a Jesuit priest.</p><p>He burned his youthful verses as inappropriate to his profession; he began  writing again in 1875 but was increasingly troubled by the tension  between his religious vocation and his delight in the sensuous world. One  of the most individual of Victorian writers, he is noted for intense  language, compressed syntax, and innovations in prosody, including  sprung rhythm. His best-known poems include �The Wreck of the Deut�  schland,� �Pied Beauty,� �God�s Grandeur,� and �The Windhover.� He  died of typhoid at age 44. His work, though not published in collected  form until 1918 (by his friend Robert Bridges), influenced many 20th-  century poets.</p><p>Hopkins, Harry L(loyd) (b. Aug. 17, 1890, Sioux City, Iowa,  U.S.� d. Jan. 29, 1946, New York, N.Y.) U.S. New Deal official. He was  a social worker in New York City through the 1920s. From 1931 to 1933  he directed the state�s emergency relief agency. After Franklin D. Roosevelt  became president in 1933, Hopkins was appointed head of the Federal  Emergency Relief Administration. In 1935 he created the Works Progress  Administration (WPA). After serving as U.S. commerce secretary (1938�  40), he made several trips for Roosevelt to London and later to Moscow  to discuss economic assistance and military strategy. In 1941 he was put  in charge of the lend-lease program. He was regarded as Roosevelt�s clos�  est personal adviser during World War II.</p><p>Hopkins, Johns (b. May 19, 1795, Anne Arundel county, Md.,  U.S.�d. Dec. 24, 1873, Baltimore, Md.) U.S. merchant and financier. He  worked with an uncle as a wholesale grocer before establishing Hopkins  Brothers wholesalers with his brothers in 1819. The firm soon prospered  in several states. It freely accepted payment for goods in whiskey, which  it then sold as Hopkins� Best. Hopkins retired in 1847 a wealthy man,  though he continued investing in Baltimore real estate and the Baltimore  and Ohio Railroad. In his will he left $7 million to fund the establishment  of Johns Hopkins University and Johns Hopkins Hospital; he also endowed  an orphanage for African American children.</p><p>Hopkins, Mark (b. Sept. 3, 1814, Richmond County, Va., U.S.�d.  March 29, 1878, Yuma, Arizona Territory) U.S. businessman who helped  build the Central Pacific (later the Southern Pacific) Railroad and for  whom San Francisco�s Mark Hopkins Hotel atop Nob Hill was named.  He was brought up in North Carolina. After an unprofitable attempt to  mine gold in California in 1851, he began selling groceries and estab�  lished one of the most prosperous mercantile houses in the state. With  three other merchants he planned a transcontinental railroad, and in 1861  they organized the Central Pacific Railroad. In 1869 the main line was  completed, meeting the Union Pacific at Promontory, Utah.</p><p>Hopkins, Pauline (Elizabeth) (b. 1859, Portland, Maine, U.S.�d.  Aug. 13, 1930, Cambridge, Mass.) U.S. novelist and playwright. She per�  formed with her family�s singing group before writing her first novel,  Contending Forces (1900). Later novels include Hagar�s Daughter  (1902), Winona (1902), Of One Blood (1903), and Topsy Templeton  (1916). The novels reflect the influence of W.E.B. Du Bois and pioneer in  using the traditional romance novel to explore racial and social themes.</p><p>Hopkins, Sarah Winnemucca or Sarah Hopkins Winne-  mucca or Thocmectony (b. c. 1844, Humboldt Sink, Mex.�d. Oct.  16, 1891, Monida, Mont., U.S.) U.S. educator, lecturer, tribal leader, and  writer. Born to a Northern Paiute family, she lived as a child with a white  family and attended a convent school, and later she served as an army  interpreter and scout. Her lecture tours in the East in the 1880s publicized  the plight of her tribe and protested government policies. Her writings,  of which Life Among the Piutes (1883) is the best known, are valuable  for their description of Indian life and their insights into the impact of  white settlement, and they are among the few contemporary Native  American works.</p><p>Hopkinson, Francis (b. Oct. 2, 1737, Philadelphia, Pa.�d. May 9,  1791, Philadelphia, Pa., U.S.) U.S. political leader and writer. After a brief  business career, he launched a successful legal practice in New Jersey. He  was appointed to the governor�s council in 1774, and in 1776 he repre�  sented New Jersey in the Continental Congress. He signed the Declara�  tion of Independence, and he later wrote articles that helped win ratification  of the U.S. Constitution. He served as judge of the admiralty court for  Pennsylvania (1779-89) and as U.S. district judge (1789-91). An accom�  plished harpsichordist and composer of religious and secular songs, he  was also known for his poetry and literary essays and for his design of  numerous governmental and organizational seals.</p><p>The Hope diamond; in the Smithsonian  Institution, Washington, D.C.</p><p>LEE BOLTIN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>hoplite &#x25BA; hornbill I 895</p><p>hoplite Vhop-.lhA Heavily armed foot soldier of ancient Greece whose  function was to fight in close formation.

They were equipped with new and heavier armour,  including a metal helmet, breastplate, and shield; each had a sword and a  6-ft (2-m) spear for thrusting rather than throwing. From then on, battles  were won not by individual champions but through the weight of massed  hoplite PHALANXes breaking through enemy ranks.

A master of carom technique, he became one of the most durable  of all sports champions, winning 51 world titles between 1906 and 1952.  In the 1940 tournament in Chicago he was undefeated in 20 matches. He  retired in 1952.</p><p>Hopper, Edward (b. July 22, 1882, Nyack, N.Y., U.S.�d. May 15,  1967, New York, N.Y.) U.S. painter. He was initially trained as an illus�  trator but later studied painting with Robert Henri. In 1913 he exhibited  in the Armory Show but spent much of his time on advertising art and  illustrative etchings. In the mid 1920s he turned to watercolours and oil  paintings of urban life. His House by the Railroad (1925) and Room in  Brooklyn (1932) depict still, anonymous figures within geometric build�  ing forms, producing the haunting sense of isolation that was to be his  hallmark. He used light to isolate figures and objects, as in Early Sunday  Morning (1930) and Night hawks (1942). His mature style was already  formed in the 1920s; his later development showed constant refinement  and an even greater mastery of light.</p><p>Hopper, Grace Murray orig. Grace Brewster Murray (b.

She received a Ph.D. from Yale Univer�  sity in 1934 and taught at Vassar College in 1931�44. As a U.S. Navy  officer (1943-86), she worked on Harvard�s Mark I (1944) and Mark II  (1945) computers, and in 1949 she helped design an improved compiler  for translating a programmer�s instructions into computer codes. She  helped devise UNI VAC I, the first U.S. commercial electronic computer  (1951), and wrote naval applications for COBOL. She received the  National Medal of Technology in 1991.</p><p>Horace orig. Quintus Horatius Flaccus (b. December 65,  Venusia�d. Nov. 27, 8 bc, Rome) Latin lyric poet and satirist. The son  of a former slave, he was educated in Rome. He fought in Brutus�s army  in the upheaval after Julius Caesar�s murder but gained the favour of  Octavian (later Augustus) and achieved virtually the status of poet laure�  ate. His early works include books of Satires and Epodes, but his fame  rests chiefly on his books of lyrical Odes and verse Epistles, including the  treatise Ars poetica, which sets down rules for the composition of poetry.  The Odes and Epistles, frequently on themes of love, friendship, and phi�  losophy, significantly influenced Western poetry from the Renaissance  through the 19th century.</p><p>Horbat Qesari See Caesarea  Horeb, Mount See Mount Sinai</p><p>horizon In pedology, a distinct layer of soil forming part of the vertical  sequence in a soil profile. Each horizon differs from the one above or  below it in colour, chemical composition, texture, and structure. The hori�  zons become differentiated during soil development because conditions  vary with depth. There are generally three major layers within any given  soil profile, and they are designated, from surface downward, as A, B,  and C horizons. The A horizon generally contains more organic matter  than the others; it is also the most weathered and leached. The B horizon  tends to be a zone of accumulation, since all or part of the mineral mat�  ter removed from the A horizon in solution may be deposited in it. The C  horizon consists chiefly of the materials from which the A and B layers  were derived; called parent materials, these are only slightly altered,  because they are in general not subjected to soil-forming processes.</p><p>horizontal bar Event in men�s gymnastics competition in which a  steel bar fixed about 8 ft (2.4 m) above the floor is used for swinging  exercises.

July 7, 1973,  Niimberg) German philosopher and social theorist. He received his Ph.D.  in philosophy at the University of Frankfurt in 1922. In 1930 he became  director of the university�s newly founded Institute for Social Research.  Under his leadership, the institute attracted an extraordinarily talented  array of philosophers and social scientists, including Theodor Adorno,  Erich Fromm, and Herbert Marcuse; collectively (with Horkheimer) they  became known as the Frankfurt school. When the Nazis came to power  in 1933, Horkheimer moved the institute to New York City, where he  directed it until 1941; he reestablished it in Frankfurt in 1950. In his 1937  essay �Traditional and Critical Theory,� he contrasted what he considered  the socially conformist orientation of traditional political philosophy and  social science to the brand of critical Marxism favoured by the institute,  an approach known as critical theory. His collaboration with Adorno, Dia�  lectic of Enlightenment (1947), is a pessimistic work that traces the ori�  gins of fascism and other forms of totalitarianism to the Enlightenment  concept of �instrumental� reason.</p><p>hormone Organic compound (often a steroid or peptide) that is produced  in one part of a multicellular organism and travels to another part to exert  its action. Hormones regulate physiological activities including growth,  reproduction, and homeostasis in vertebrates; molting and maintenance of  the larval state (see larva) in insects; and growth, bud dormancy, and leaf  shedding in plants. Most vertebrate hormones originate in specialized tis�  sues (see endocrine system; gland) and are carried to their targets through  the circulation. Among the many mammalian hormones are ACTH, sex  hormones, thyroxine, insulin, and epinephrine. Insect hormones include  ecdysone, thoracotropic hormone, and juvenile hormone. Plant hormones  include ethylene, abscisin, auxins, gibberellins, and cytokinins.</p><p>Hormoz or Hormuz \hor-'miizV formerly Ormuz \6r-'miiz\ Island  and town, Iran.

She starred in many  films, including Stormy Weather (1943) and The Wiz (1978). Her album  Lena Horne at the Waldorf-Astoria (1957) was a great success, as was her  appearance in the musical Jamaica (1957). Her one-woman show, Lena  Horne: The Lady and Her Music (1981), was hailed as her masterpiece.  She continued to perform and record into the 1990s.</p><p>Horne, Marilyn (b.

In 1954 Horne dubbed the  singing voice of Dorothy Dandridge in the film Carmen Jones , and that  same year, she made her opera debut with the Los Angeles Guild Opera.  Her long and influential association with the bel canto (a singing style  based on an exact control of the intensity of vocal tone) repertoire began  in 1962, and she played an important role in the revival of operas by  George Frideric Handel and Gioacchino Rossini. Her distinctive voice was  even throughout its remarkably wide range, and she had virtuoso control  of breath and pitch.

Its earliest ancestor was the dawn horse  (see Eohippus). The only living horse not descended from the domestic  horse is Przewalski's horse. The horse was apparently first domesticated by  nomadic peoples of Central Asia in the 3rd millennium bc. For many cen�  turies horses were primarily used in warfare. The saddle was introduced  in China in the first centuries ad. Horses were reintroduced to the New  World, after wild horses had become extinct there some 10,000 years ear�  lier, by the Spanish in the 16th century. A mature male is called a stallion  or, if used for breeding, a stud; mature females are called mares. A cas�  trated stallion is called a gelding. Young horses (foals) are also known as  colts (males) and fillies (females). A horse�s height is measured in 4-in.  (10.2-cm) units, or hands, from the highest point of the back (withers) to  the ground. Breeds are classified by size and build: draft (heavy) horses  (e.g., Belgian, Percheron) are heavy-limbed and up to 20 hands high;  ponies (e.g., Shetland, Iceland) are less than 14.2 hands high; and light  horses (e.g., Arabian, Thoroughbred) are intermediate, rarely taller than 17  hands.</p><p>the mid-18th century as well, as gambling came to be a standard part of  horse racing.

Thor�  oughbred racing, conducted on a flat, elliptical, mile-long track, attracts  the largest purses, followed by harness racing and quarter-horse racing.  The most important U.S. Thoroughbred races are the Kentucky Derby,  Preakness Stakes, and Belmont Stakes. See also steeplechase.</p><p>horsefly Any member of the dipteran genus Tabanus or, more generally,  of the family Tabanidae. These stout flies range from as small as a house�  fly to as large as a bumblebee. Sometimes called greenheaded monsters,  horseflies have metallic or iridescent eyes. Adults are fast, strong fliers  usually found around streams, marshes, and wooded areas. They may  carry animal diseases, including anthrax, tularemia, and trypanosomiasis.  The bites of the bloodsucking females can be painful, and a swarm may  suck more than 3 oz (about 90 ml) of blood a day from an animal. Males  feed on nectar, honeydew, and plant sap. Horseflies of the genus Chrysops,  usually called deerflies, are smaller and have dark markings on the wings.</p><p>horsehair worm or hairworm or gordian worm Any of about  250-300 species (class Nematomorpha, or Gordiacea; phylum Aschelm-  inthes) of long, thin worms. The young are parasites in arthropods; the  adults are free-living in the sea or in freshwater. The hairlike body some�  times grows to a length of about 39 in. (1 m).</p><p>horsemanship Art of training, riding, and handling horses. Good  horsemanship requires that a rider control the animal�s direction, gait, and  speed with maximum effectiveness and minimum effort. Natural aids are  a rider�s balance, hands, voice, and legs; artificial aids include bits, reins,  saddles, and spurs. Horsemanship was important to cavalrymen and cow�  boys, and is the fundamental element of dressage.</p><p>horsepower Common unit of power, the rate at which work is done.  In the English system, one horsepower equals 33,000 foot-pounds of work  per minute�that is, the power necessary to lift a total of 33,000 lbs a  distance of one foot in one minute. This value was adopted by James Watt  in the late 18th century after experiments with strong dray horses and is  actually about 50% more than the rate an average horse can sustain for a  working day. The electrical equivalent of one horsepower is 746 watts in  the International System of Units; the heat equivalent is 2,545 BTU per  hour. The metric horsepower (see metric system) equals 4,500 kg-m per  minute (32,549 foot-pounds per minute), or 0.9863 horsepower.</p><p>horseradish Hardy perennial plant ( Armoracia lapathifolia ) of the  mustard family, native to Mediterranean lands and grown throughout the  temperate zones. Its hotly pungent, fleshy root is used as a condiment and  is traditionally considered medicinal. In many cool, moist areas it has  become a troublesome weed. The plant bears small white flowers, small  oblong pods, and large, coarse, glossy-green basal leaves arising on long  stems from the crown atop the large white root.</p><p>pastern</p><p>of hip</p><p>croup  dock  tail  flank</p><p>�gaskin  � hock</p><p>forearm</p><p>knee</p><p>coronet</p><p>heel</p><p>forehead</p><p>cheek</p><p>muzzle  neck  jugular groove  shoulder  breast �</p><p>External features of a horse.</p><p>� MERRIAM-WEBSTER INC.</p><p>horse-chestnut family Family Hippocastanaceae, composed of the  buckeyes and the horse chestnuts (genus Aesculus), native to the northern  temperate zone.

The  Champs-Elysees in Paris is lined with rows of horse-chestnut trees.</p><p>horse racing Sport of running horses at speed. Typically, Thorough�  breds are raced with a rider astride and Standardbreds with the horse pull�  ing a conveyance with a driver. Though racing has an ancient lineage, the  first regularly organized national races were established in England under  Charles II (r. 1660-85), and the first in North America were held on Long  Island in 1665. These early races were match events between two or three  horses and were run in heats; a horse had to complete at least two heats  to be judged the winner. By the mid-18th century, larger fields of runners  and single-race �dash� events were the norm. Handicap racing emerged in</p><p>horseshoe pitching Game for two or four players in which a horse�  shoe is thrown so as to encircle or land as close as possible to a stake. A  horseshoe encircling the stake is called a ringer and counts for the high�  est score. The game may have derived from quoits, and it became espe�  cially popular in the U.S. and Canada. Regulation games are played to a  winning score of 50, informal games to 21.</p><p>horseshoe crab Any of four extant species of marine arthropods  (order Xiphosura, subphylum Cheli-  cerata), found on the eastern coasts  of Asia (three species) and North  America (one species). Despite the  name, horseshoe crabs are not crabs;  they are more closely related to scor�  pions. Fossil relatives date back 505  million years. They are most abun�  dant in estuarine waters. The North  American species, Limulus polyphe-  mus, can grow to more than 2 ft (60  cm) long. The body consists of three  parts hinged together: a broad,  horseshoe-shaped cephalothorax; a  much smaller, segmented abdomen;</p><p>and a long, sharp tail-spine, or telson. They spawn on sandy beaches in  spring and summer. Adults feed on marine worms; larvae feed on small  organisms.</p><p>Horseshoe crab (Limulus polyphemus).</p><p>RUNK/SCHOENBERGER FROM GRANT HEILMAN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>898 I horsetail &#x25BA; hot spot</p><p>horsetail also called scouring rush Any of the 30 species of rush-  like (see rush), conspicuously segmented, perennial herbaceous plants that  make up the genus Equisetum. They grow in moist, rich soils everywhere  except Australasia. Some are evergreen; others send up new shoots every  year. The stems contain abundant silicate minerals and other minerals. The  leaves are merely sheaths that encircle the shoots. An ancient plant, the  horsetail�s relatives date to the Carboniferous Period. The common horse�  tail ( E . arvense) is widespread along streambanks and in meadows in  North America and Eurasia. Though poisonous to livestock, horsetails are  used in folk medicines. Because of their abrasive stems, some species  have been used in polishing tools.</p><p>Horta, Victor, Baron (b. Jan. 6, 1861, Ghent, Belg.�d. Sept. 8,1947,  Brussels) Belgian architect. From 1892 he designed numerous buildings  in Brussels, becoming a leading exponent of the Art Nouveau style. His  Hotel Tassel (1892-93) was a pioneering example of the new style. His  chief work was the Maison du Peuple (1896-99), the first structure in  Belgium to have a largely iron-and-glass facade. From 1912 he directed  the Academie des Beaux-Arts, and he designed the Palais des Beaux-Arts</p><p>(1922-28).</p><p>Horthy \'hor-te\ Miklos (Nagybanyai) (b. June 18, 1868, Ken-  deres, Hung., Austria-Hungary�d. Feb. 9, 1957, Estoril, Port.) Hungarian  naval officer and regent (1920-44). He served with distinction as a naval  commander in World War I and was promoted to admiral in 1918. In 1919  he led an army against the communist regime of Kun Bela . In 1920 the  Hungarian parliament voted to restore the monarchy and elected Horthy  regent of Hungary, but he thwarted the efforts of Charles IV to recover his  throne. He supported Germany in World War II, though his efforts to extri�  cate Hungary from the war led to his forced abdication and abduction by  the Germans in 1944. Released in 1945, he retired to Portugal.</p><p>horticulture Branch of agriculture concerned with the cultivation of  garden plants�generally fruits, veg�  etables, flowers, and ornamentals  such as plants used for landscaping  (see landscape gardening). Propaga�  tion, the controlled perpetuation of  plants, is the most basic horticultural  practice. Its objectives are to  increase the numbers of a plant and  to preserve its essential characteris�  tics. Propagation may be achieved  sexually by use of seeds or asexually  by use of techniques such as cutting,  grafting (see graft), and tissue culture.</p><p>Successful horticulture depends on  extensive control of the environ�  ment, including light, water, tem�  perature, soil structure and fertility,  and pests. Two important horticul�  tural techniques are training (chang�  ing a plant�s orientation in space)  and pruning (judicious removal of  plant parts), used to improve the  appearance or usefulness of plants.</p><p>See also floriculture.</p><p>Horus Ancient Egyptian god with  the head of a falcon, whose eyes  were the sun and moon. The kings of  Egypt were called living incarna�  tions of Horus. During the 1st  dynasty Horus was known princi�  pally as an opponent of Seth, but  after 2350 bc he became associated  with the Osiris cult and was identi�  fied as the son of Osiris. He  destroyed Seth, the killer of Osiris,  and became ruler of all Egypt. His  left eye (the moon) was damaged by  Seth but was healed by Thoth. In the  Ptolemaic period, the victory of  Horus over Seth became a symbol of  Egypt triumphing over its occupiers.</p><p>Horyu Temple Japanese Horyu-ji Vhor-yu-je\ Buddhist complex  near Nara, Japan, comprising the oldest known wood buildings in the  world. The temple was founded by Prince Shotoku in 607 during the  Asuka period, destroyed by fire in 670, and reconstructed c. 680-708. It  retains the chu-mon (middle gate) of the roofed cloister enclosing the  rectangular temple precinct, a five-storied pagoda, and a kondd (main  hall).</p><p>Hosea Mio-'za-o, ho-'ze-3\ (fl. 8th century bc) First of the 12 Minor  Prophets in the Hebrew scriptures, traditional author of the book of Hosea.  (His prophecy is part of a larger book, The Twelve, in the Jewish canon.)  He began to prophesy during the reign of Jeroboam II and continued until  near the fall of the northern kingdom of Israel in 721 bc. The book is an  allegory in which the prophet is presented as a man married to a harlot  or an adulterous wife. This troubled relationship stands for the betrayal  of God by Israel, which has �played the harlot� by dallying with Canaan-  ite religion.</p><p>hosiery Knit or woven coverings for the feet and legs, worn inside  shoes. In the 8th century bc, Hesiod referred to linings for shoes; the  Romans wrapped their feet, ankles, and legs in long strips of leather or  woven cloth. Knitted socks were discovered in Egyptian tombs of the  3rd-6th century ad. The first knitting machine was invented in England in  the 16th century. Full-fashioned stockings were knitted flat, then shaped  and seamed up the back by hand. In the 19th century, seamless stockings,  mostly of cotton, were knitted on circular machines, but they did not fit  well; seamless hose did not become popular until the 1940s, when nylon  replaced silk for dress hose. Pantyhose were introduced in the 1960s.</p><p>hospice Home or hospital for relieving physical and emotional suffer�  ing of dying persons. In patients expected to live only months or weeks,  hospice care offers an alternative to aggressive life-prolonging measures,  which often only increase discomfort and isolation. Hospices provide a  sympathetic environment in which prevention (not just control) of physi�  cal pain has top priority, along with patients� emotional and spiritual  needs. Care may be provided in a health facility, on an outpatient basis,  or at home.</p><p>hospital Institution for diagnosing and treating the sick or injured, hous�  ing them during treatment, examining patients, and managing childbirth.  Outpatients, who can leave after treatment, come in for emergency care  or are referred for services not available in a private doctor�s office. Hos�  pitals may be public (government-owned) or private (profit-making or  not-for-profit); in most nations except the U.S., most are public. They may  also be general, accepting all types of medical or surgical cases, or spe�  cial (e.g., children�s hospitals, mental hospitals), limiting service to a  single type of patient or illness. However, general hospitals usually also  have specialized departments, and special hospitals tend to become affili�  ated with general hospitals.</p><p>Hospitallers See Knights of Malta, Teutonic Order</p><p>hosta Vha-sts, 'ho-staN Any of about 40 species of hardy herbaceous  perennials, also called plantain lily, of the genus Hosta , in the uly family,  native to eastern Asia. They prefer light shade but will grow under a vari�  ety of conditions. They are frequently grown for their conspicuous foli�  age, which may be light to dark green, yellow, blue, or variegated. The  ribbed leaves grow in a cluster at the base, and stalks bearing clusters of  tubular white or bluish-purple flowers emerge from the leaves.</p><p>hot rod Automobile rebuilt or modified for high speed, fast accelera�  tion, or sporty appearance. A wide range of automobiles may be called  hot rods, including some of those used in drag racing as well as those  used in recreational cruising. They may be composed of used or new parts.  Some are intended primarily for exhibition.</p><p>hot spot Region of the Earth�s upper mantle that up wells to melt through  the crust to form a volcanic feature. Most voLCANOes that cannot be  ascribed either to a subduction zone or to seafloor spreading at midocean  ridges are attributed to hot spots. The 5% of known world volcanoes not  closely related to such plate margins (see plate tectonics) are regarded as  hot-spot volcanoes. Hawaiian volcanoes are the best examples of this  type, occurring near the centre of the northern portion of the Pacific Plate.  A chain of extinct volcanoes or volcanic islands (and seamounts), such  as the Hawaiian chain, can form over millions of years where a lithos�  pheric plate moves over a hot spot. The active volcanoes all lie at one end  of the chain or ridge, and the ages of the islands or the ridge increase with  their distance from those sites of volcanic activity.</p><p>Horus offering a libation, bronze  statue, 22nd dynasty (c. 800 bc); in the  Louvre, Paris.</p><p>GIRAUDON/ART RESOURCE</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>hot spring &#x25BA; house mouse I 899</p><p>hot spring or thermal spring Spring that issues water at tempera�  tures substantially higher than the air temperature of the surrounding  region. Most hot springs result from the interaction of groundwater with  magma or with solid but still-hot igneous rocks. Some, however, are not  related to volcanic activity. In such cases, deep circulation of water is  thought to carry the water to the lower parts of the Earth�s crust, where  the temperature of the rocks is high.</p><p>Hot Springs National Park National park, central Arkansas, U.S.  Established in 1921, it occupies an area of 9 square mi (23 sq km). It is  centred on 47 thermal springs, from which more than 850,000 gallons  (3,200,000 litres) of water, with an average temperature of 143 �F (62  �C), flow daily. The springs, long used by the Indians and probably vis�  ited by Hernando de Soto in 1541, drew Spanish and French visitors in  search of health benefits in the 1700s. The city of Hot Springs (pop., 2000:  35,750), a health and tourist resort and boyhood home of U.S. Pres. Bill  Clinton, was settled in 1807 and incorporated in 1876.</p><p>hotel Building that provides lodging, meals, and other services to the  traveling public on a commercial basis. Inns have existed since ancient  times (e.g., along the Roman road system during the Roman Empire) to  serve merchants and other travelers. Medieval European monasteries  operated inns to guarantee haven for travelers in dangerous regions. The  spread of travel by stagecoach in the 18th century stimulated the devel�  opment of inns, as did the Industrial Revolution. The modem hotel was  largely the result of the railroads; when traveling for pleasure became  widely popular, large hotels were often built near railroad stations. In 1889  the Savoy Hotel in London set a new standard, with its own electricity  and a host of special services; the Statler Hotel in Buffalo, N.Y. (1908),  another landmark, catered to the growing class of business travelers. After  World War II, new hotels tended to be larger and were often built near  airports. Hotel chains became common, making purchasing, sales, and  reservations more efficient. Hotels fall into three categories: transient  hotels; resort hotels, intended primarily for vacationers; and residential  hotels, essentially apartment buildings offering room and meal service.

In Rome (1764-68)  he achieved immediate fame with an anatomical study of a standing man  (c. 1767), casts of which were widely used in art academies. He became  a member of the Royal Academy in Paris (1777) with his reclining Mor�  pheus. He produced numerous religious and mythological works that are  definitive expressions of the decorative 18th-century Rococo style of  sculpture. His greatest strength was in capturing the individuality of his  portrait subjects, including such luminaries as Denis Diderot, Catherine II  the Great, Benjamin Franklin, the Marquis de Lafayette, and Voltaire. In the  U.S. he made a marble statue of George Washington (1788).

He served as president of the Republic of Texas (1836-38, 1841�  44) and helped it to win statehood (1845); he then served in the U.S.  Senate (1846-59). He was elected governor in 1859, but his pro-Union  views were opposed by Democratic state leaders, who voted to secede in  1861. After he refused to swear allegiance to the Confederacy, he was  deposed. The city of Houston was named in his honour.</p><p>Sam Houston, photograph by Mathew  Brady</p><p>LIBRARY OF CONGRESS, WASHINGTON, D.C.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Hovenweep &#x25BA; Howe I 901</p><p>Hovenweep Vho-v3n-,wep\ National Monument National monu�  ment, southwestern Colorado and southeastern Utah, U.S. Established in  1923 and covering 785 acres (318 hectares), it consists of six groups of  pre-Columbian Indian ruins, whose towers are excellent examples of  Pueblo Indian architecture of the period ad 1100-1300.

A nephew of William Howe, he began work  as a mechanic. In 1846 he was granted a patent for the first practical sew�  ing machine. It attracted little attention, and he moved to England and  worked to perfect his machine for use with leather and similar materials.  When he returned the next year, he found that sewing machines were  being widely made and sold; he finally established his patent rights in  1854. His invention soon revolutionized the garment industry. See also  Isaac Merritt Singer.</p><p>Howe, Gordie in full Gordon Howe (b. March 31, 1928, Floral,  Sask., Can.)

As vice admiral (from 1775), he commanded in North America  (1776-78), defeating French attempts to take Newport, R.I. After return�  ing to England, he commanded the Channel fleet against the French and  Spaniards and served as first lord of the Admiralty (1783-88). In 1793 he  again commanded the Channel fleet. His victory against the French on  June 1, 1794, provided an example of tactical excellence for his succes�  sors, including Horatio Nelson.</p><p>Howe, William Howe, 5th Viscount (b.

In the American Revolution, he succeeded  Thomas Gage as supreme commander of British forces in North America  in 1776. He soon captured New York City and the surrounding area, and  in 1777 he led British troops to victories at the Battles of the Brandywine  and of Germantown. Moving his forces to Philadelphia, he left troops  under John Burgoyne vulnerable in New York state, thus contributing to  the British defeat at the Battles of Saratoga.

May 11, 1920, New York, N.Y.) U.S. novelist and critic. He  wrote a campaign biography of Abraham Lincoln (1860) and served as  consul in Venice during Lincoln�s administration. As editor of the Atlan�  tic Monthly (1871-81), he became a preeminent figure in late 19th-century  American letters. A champion of literary realism, he was one of the first  to recognize the genius of Mark Twain and Henry James. His own novels  (from 1872) depict America as it changed from a simple, egalitarian soci�  ety where luck and pluck were rewarded to one in which social and eco�  nomic gulfs were becoming unbridgeable. His best-known work, The Rise  of Silas Lapham (1885), is about a self-made man�s efforts to fit into Bos�  ton society. Howells risked his livelihood with his plea for clemency for  the anarchists involved in the Haymarket Riot, and his deepening disillu�  sionment with American society is reflected in the late novels Annie Kil-  burn (1888) and A Hazard of New Fortunes (1890).</p><p>howler monkey Any of several species of slow-moving tropical  American monkeys (genus Alouatta) noted for their roaring cries, which  carry over a distance of 2-3 mi (3-5 km).

He became prime minister (1944-54), and  in 1946 he forced King Zog to abdicate. Albania�s economy was revo�  lutionized under Hoxha�s rule, and he transformed the country from a  semifeudal relic of the Ottoman Empire into an industrialized economy.  To enforce his radical programs he resorted to brutal Stalinist tactics,  making Albania the most tightly controlled society in Europe.

Within the framework of Albert Einstein�s theory of relativ�  ity, Hoyle formulated a mathematical basis for the steady-state theory of  the universe, making the expansion of the universe and the creation of  matter interdependent. Controversy about the theory grew in the late  1950s and early �60s. New observations of distant galaxies and other phe�  nomena supported the big-bang model and weakened the steady-state  theory, which has since generally fallen out of favour. Though forced to  alter some of his conclusions, Hoyle persistently tried to make his theory  consistent with new evidence.

U.S. astronomer. He earned  a degree in mathematics and astronomy at the University of Chicago, then  made a brief foray into law before returning to astronomy. After earning  his Ph.D., he began working at Mount Wilson Observatory. In 1922-24  he discovered that certain nebulae contained Cepheid variable stars; he  determined that these were several hundred thousand light-years away  (outside the Milky Way Galaxy) and that the nebulae they were in were  actually other galaxies. In studying those galaxies, he made his second  remarkable discovery (1927): that the galaxies were receding from the  Milky Way at rates that increased with distance. This implied that the uni�  verse, long considered unchanging, was expanding (see expanding uni�  verse); even more remarkable, the ratio of the galaxies� speed to their  distance was a constant (see Hubble's constant). Hubble�s original calcu�  lation of the constant was incorrect; it made the Milky Way larger than</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>904 I Hubble Space Telescope &#x25BA; Hudson's Bay Co.</p><p>all other galaxies and the entire universe younger than the surmised age  of Earth. Later astronomers determined that galaxies were systematically  more distant, resolving the discrepancy.</p><p>Hubble Space Telescope (HST) Most sophisticated optical obser�  vatory ever placed into orbit around Earth. Because it is above Earth�s  obscuring atmosphere, it can obtain images much brighter, clearer, and  more detailed than ground-based telescopes can. Named for Edwin Hub�  ble, it was built under NASA supervision and deployed on a 1990 space-  shuttle mission. The reflector telescope�s mirror optics gather light from  celestial objects and direct it to an array of cameras and spectrographs  (see spectroscopy). A defect in the primary mirror initially caused it to pro�  duce fuzzy images; in 1993 another shuttle mission corrected this and  other problems. Subsequent missions to the HST have been for mainte�  nance, repairs, and instrument upgrades.</p><p>Hubble's constant Constant used to relate the velocities of remote  galaxies to their distances from Earth. Denoted H and named in honour  of Edwin Hubble, it expresses the rate of expansion of the universe. Its  actual value has been debated for decades; improved measurements have  naiTOwed the range in which it falls to about 10.5-14 mi/second (17-23  km/second) per million light-years. The reciprocal of H gives the time,  in seconds, since the galaxies began to separate from each other�i.e., the  approximate age of the universe. Hubble used the redshifts of distant gal�  axies measured by Vesto Slipher (1875-1969) and his own distance esti�  mates of those galaxies to establish the cosmological velocity-distance  law (Hubble law): velocity = H x distance, according to which the greater  a galaxy�s distance, the faster it is receding.

It has an area of 72,400  sq mi (187,500 sq km), and its capital is Wuhan. Part of the kingdom of  Chu (3rd century bc), it became part of the Qin dynasty after being sub�  jugated by Shihuangdi. Until the reign of Kangxi, Hubei and Hunan  formed one province; they were divided in the mid-17th century. The area  was the scene of battles after the 1850 Taiping Rebellion. The revolution of  1911/12 (see Nationalist Party) began in Hubei. The province was heavily  bombed during the Sino-Japanese War of 1937�45. Restoration began  after the communist Chinese takeover.

English navigator and explorer. Sailing for the Mus�  covy Company of London in search of the Northeast Passage to the Far  East, he was blocked by ice fields. In 1609 he set out in the Half Moon  to find a similar passage for the Dutch East India Company, but, when  stopped by storms, he instead sought the Northwest Passage, which he  had recently heard about from other explorers, and cruised along the  Atlantic coast and up the Hudson River. In 1610 he set out again for  America, this time on behalf of the Muscovy Company and the English</p><p>East India Company, and discovered Hudson Bay. Finding no outlet to the  Pacific and in the close confinement of an Arctic winter, Hudson�s crew  fell to quarreling, and on the homeward voyage they mutinied and set  Hudson adrift in a small boat, never to be found. His discoveries formed  the basis for Dutch colonization of the Hudson River and for English  claims to much of Canada.</p><p>Hudson, Rock orig. Roy Harold Scherer, Jr. (b.

His manly, wholesome good looks made him a popu�  lar star in Douglas Sirk melodramas such as Magnificent Obsession (1954)  and All That Heaven Allows (1955), and he displayed a flair for comedy  in a series of films with Doris Day, including Pillow Talk (1959), Come  September (1961), and Send Me No Flowers (1964). He later starred in  the television series McMillan and Wife (1971-77). His death from AIDS  greatly increased awareness of the disease.</p><p>Hudson Bay Inland sea, indenting east-central Canada. With an area  of 480,000 sq mi (1,243,000 sq km), it is bounded by Nunavut, Manitoba,  Ontario, and Quebec. It is connected with the Atlantic Ocean via the Hud�  son Strait and with the Arctic Ocean via the Foxe Channel. Named for  Henry Hudson, who navigated its eastern coast in 1610, the bay and the  surrounding area, known as Rupert's Land, were controlled by the Hud�  son's Bay Company (1821-69). Hudson Bay is shallow, with an average  depth of 330 ft (100 m); the coast is mainly a marshy lowland. The islands  it contains are administratively part of Nunavut. For conservation pur�  poses, the Canadian government has designated the whole Hudson Bay  basin a �mare clausum� (closed sea).</p><p>Hudson River River, New York, U.S. Originating in the Adirondack  Mountains and flowing for about 315 mi (507 km) to New York City, it  was named for Henry Hudson, who explored it in 1609. Dutch settlement  of the Hudson valley began in 1629. The river became a strategic water�  way during the American Revolution and was the scene of many battles.  Linked by canals with the Great Lakes and with the Delaware River and  lower St. Lawrence River valleys, the Hudson is now a major commercial  route; its southern end forms the New York-New Jersey boundary.</p><p>Hudson River school U.S. landscape painters of several generations,  active c. 1825-70. The first of them were inspired by the natural beauty  of New York�s Hudson River valley and Catskill Mountains. The leading  figures were Thomas Cole, Asher B. Durand, and Thomas Doughty (1793�  1856). Others, such as Frederic Edwin Church and George Inness, had stud�  ied in Europe and found inspiration in the grandiose landscapes of J.M.W.  Turner. By mid century they were widely admired for their depictions of  a common theme, the splendour of the untamed U.S. landscape. The name  Hudson River school, applied retrospectively, is extended to artists of the  same vision who painted imposing scenes of the Rocky Mountains, Grand  Canyon, and Yosemite Valley. The first native school of painting in the  U.S., it remained the dominant school of landscape painting throughout  the 19th century.</p><p>Hudson Strait Arm of the Atlantic Ocean between Baffin Island and  northern Quebec, northeastern Canada. Linking Hudson Bay and Foxe  Basin with the Labrador Sea, it is about 500 mi (800 km) long and 40-150  mi (65-240 km) wide. It is navigable only during late summer and early  autumn, but icebreakers make the passage most of the year. Partly  explored in 1578 by English navigator Martin Frobisher, it was fully navi�  gated by Henry Hudson in 1610 and became a main route for the Hudson's  Bay Company�s ships.</p><p>Hudson's Bay Co. Corporation prominent in Canadian economic and  political history. It was incorporated in England (May 2, 1670) to seek the  Northwest Passage to the Pacific, to occupy lands adjacent to Hudson Bay,  and to carry on commerce. The lands granted to the company, known as  Rupert's Land, extended from Labrador west to the Rocky Mountains and  from the headwaters of the Red River on the southern Canadian border  north to Chesterfield Inlet on Hudson Bay. The company first engaged in  the fur trade and established trading posts around Hudson Bay. By 1783  competitors had formed the North West Co., and armed clashes contin�  ued until the two companies merged in 1821. The company was given  exclusive fur-trade rights until 1858, when the monopoly was not renewed  and independent companies entered the fur trade. In 1870 the company  sold its territories to the government in exchange for �300,000 and min�  eral rights to lands around the posts and a fertile portion of western</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Hue &#x25BA; Hugh River I 905</p><p>Canada.

The  seat of the Chinese military authority in the kingdom of Nam Viet c. 200  bc, it passed to the Chams c. ad 200. In 1306 it was ceded to Dai Viet  (Vietnam). It is the site of the imperial citadel, from which the Nguyen  family reigned from the mid-16th to the mid-20th century. It was occu�  pied by the Japanese (1940�45). It became the seat of a committee of  noncommunist Vietnamese in April 1947 but lost this role in 1949, when  the newly declared state of Vietnam chose Saigon (see Ho Chi Minh City)  as its capital.

As head of  the conservative German National People's Party (from 1928), he contrib�  uted to Adolf Hitler�s rise to power. In 1931 he formed an alliance of  nationalist and conservative elements to topple the Weimar government;  though his effort failed, large contributions from German industrialists  aided the Nazi Party�s growth.

He found that using estrogen  to block male hormones could slow the growth of prostate cancer. He also  showed that removing the ovaries and adrenal glands, which produce  estrogen, could reverse tumour growth in some breast cancers. Drugs are  now used to block estrogen production in such cases. He shared a 1966  Nobel Prize with Peyton Rous (1879-1970).</p><p>Hugh Capet \'ka-pot\ (b. c. 938�d. Oct. 14, 996, Paris, Fr.) King of  France (987-996), the founder of the Capetian dynasty. The son of a  Frankish duke, he inherited vast estates in the regions of Paris and  Orleans, which made him one of the most powerful vassals in France and  a serious threat to the Carolingian king, Lothar. By 985 Hugh was the  ruler of France in all but name, and two years later he was elected king.  He immediately crowned his own son to ensure the line of succession, a  practice continued until the time of Louis VII. He mediated disputes among  French nobles and survived a conspiracy to betray him to Otto III.</p><p>Hugh of Saint-Victor (b. 1096�d. Feb. 11, 1141, Paris, Fr.)

His  two terms as governor of New York (1906-10) were marked by exten�  sive reform. He was appointed to the Supreme Court of the United States  in 1910 but resigned in 1916 to run as the Republican presidential can�  didate. After losing the election to Woodrow Wilson in a close race, he  returned to his law practice. As secretary of state (1921-25), he planned  and chaired the Washington Conference (1921-22). He served as a mem�  ber of the Hague Tribunal (1926-30) and the Permanent Court of Inter�  national Justice (1928-30) before being appointed chief justice of the U.S.  Supreme Court in 1930 by Pres. Herbert Hoover. He led the court through</p><p>the great controversies arising out the New Deal legislation of Pres. Frank�  lin Roosevelt. Although generally favouring the exercise of government  power, he spoke for the court in invalidating (in Schechter Poultry Corp.  v. U.S.) a principal New Deal statute, and he attacked Roosevelt�s court�  packing plan (1937). He wrote the opinion sustaining collective bargain�  ing under the Wagner Act. He served until 1941.</p><p>Hughes, Howard (Robard) (b. Dec. 24, 1905, Houston, Texas,  U.S.�d. April 5, 1976, in an airplane over southern Texas) U.S. manu�  facturer, aviator, and movie producer. He left college at age 17 to take  control of his late father�s Hughes Tool Company, which owned the patent  to an oil-drilling tool; the company would form the future basis for Hugh�  es�s vast fortune. In the early 1930s he founded Hughes Aircraft Com�  pany. In 1935 he set a speed record of 352 mph (567 km/hr) in a plane  he designed. In 1938 he flew around the world in a record 91 hours. In  1947 he built and piloted the only flight of a wooden eight-engine flying  boat unflatteringly nicknamed �the Spruce Goose.� In the 1930s he pro�  duced several movies in Hollywood, and he owned RKO Pictures in the  early 1950s. He held controlling stock in Trans World Airlines but was  forced to sell it in 1966 following legal action. After about 1950 he  became a famously eccentric recluse, and after his death his forged mem�  oirs and his several wills became a source of scandal.</p><p>Hughes, (James Mercer) Langston (b.

After Plath�s 1963  suicide he wrote little for three years, then began publishing prolifically,  often in collaboration with illustrators or photographers. His collections  include Wodwo (1967), Crow (1970), Cave Birds (1975), Gaudete (1977),  and Wolf Watching (1989). His most characteristic work emphasizes the  cunning and savagery of animal life in harsh, sometimes disjunctive lines.  He wrote many volumes for children (including The Iron Man, 1968) and  edited the journal Modern Poetry in Translation. In 1984 he became Brit�  ain�s poet laureate. Birthday Letters (1998), published shortly before his  death, consists of revealing poems about his relationship with Plath.</p><p>Hugli River or Hooghly River \'hii-gle\ River, northeastern India.

With his verse drama  Cromwell (1827), he emerged as an  important figure in Romanticism. The  production of his poetic tragedy Her-  nani (1830) was a victory for  Romantics over traditional classi�  cists in a well-known literary battle.</p><p>His later plays included Le Roi  s �amuse (1832) and Ruy Bias (1838).</p><p>His best-known novels are The  Hunchback of Notre Dame (1831),  an evocation of medieval life, and  Les Miserables (1862), the story of  the convict Jean Valjean; their huge  popularity made him at that time the  most successful writer in the world.</p><p>In later life he was a politician and  political writer. He spent the years  1851-70 in exile for his republican  views, producing his most extensive  and original works, including Les Chatiments (1853), poems of political  satire; Les Contemplations (1856); and the first installment of The Leg�  end of the Centuries (1859, 1877, 1883).

The first French  Huguenot community was founded in 1546, and the confession of faith  drawn up by the first synod in 1559 was influenced by the ideas of John  Calvin. Their numbers increased rapidly and they became a political force,  led by Gaspard II de Coligny. Conflicts with the Roman Catholic govern�  ment and others, including the House of Guise, led to the Wars of Religion  (1562-98). A Huguenot political party was formed in 1573 to fight for  religious and civil liberties. The powerful anti-Huguenot Holy League was  formed in 1576. Henry IV ended the civil wars by abjuring Protestantism  in 1593 and converting to Catholicism, but in 1598 he promulgated the  Edict of Nantes, granting rights to Protestants. Civil wars occurred again  in the 1620s, the Huguenots lost their political power, and they contin�  ued to be harassed and forcibly converted. In 1685 Louis XIV revoked the  Edict of Nantes; over the next several years, more than 400,000 French  Protestants left France.</p><p>Huhehot See Hohhot</p><p>Hui \'hii-e\ Muslim people of western China.

The rich Luzon plain  was farmed by a large tenant-farmer population working on vast estates,  a situation that led to periodic peasant revolts. The area became a focal  point for communist organizers in the 1930s. One communist organiza�  tion, the Hukbalahap (or Huks), was a successful anti-Japanese guerrilla  group during World War II (1939�45). By the war�s end it had also seized  most of the Luzon large estates, established a government, and was col�  lecting taxes. When the Philippines became independent in 1946, the Huks  began a rebellion after they were prevented from taking government seats  to which they had been elected. They were successful for four years and  in 1950 nearly seized Manila.

His major effort was  reserved for an intensive study of learning that produced the dominant  learning theory of the 1940s and �50s�that learning was based on �habit  strength.� His important Mathematico-Deductive Theory of Rote Learn�  ing (1940) was followed by his highly influential Principles of Behavior  (1943). Relying on the work of Edward L. Thorndike and John B. Watson,  he attempted to develop a rigorous theory of learning that would account  for all behaviours, human and animal. He and his followers produced  many experiments and theoretical concepts, and their work dominated the  experimental literature for more than two decades, but it eventually was  replaced by a more cognitive psychology that provided a role for mental  events.</p><p>Hull, Cordell (b.

He served  briefly in the U.S. Senate (1931-33). As secretary of state under Pres.  Franklin D. Roosevelt (1933-44), he worked for international agreements  to reduce high tariff barriers. He helped to improve U.S. relations with  Latin America through what came to be known as the Good Neighbor  Policy. In East Asia he rejected a proposed �Japanese Monroe Doctrine�  that would have given that country a free hand in China (1934). When  the U.S. entered World War II, Hull began to plan an international post�  war peacekeeping body.

He distin�  guished himself in the undeclared naval war with France at that time and  in the Tripolitan War (1801-1805). Early in the War of 1812 he engaged  the British frigate Guerriere and, after a fierce battle, rendered it a wreck.  He was recognized as one of the navy�s ablest commanders, and his ship  became known as �Old Ironsides.� He commanded the U.S. squadrons in  the Pacific (1824-27) and in the Mediterranean (1839^-1).</p><p>Hull, William (b.

In 1805  he was appointed governor of Michigan Territory. At the outbreak of the  War of 1812, he was appointed brigadier general and charged with  defending Michigan and attacking Canada. His poorly planned invasion  of Canada forced him to retreat to Detroit, where he surrendered without  a fight. He was court-martialed and convicted of cowardice and neglect  of duty; his death sentence was remitted by Pres. James Madison because  of his earlier service.</p><p>Hulse, Russell Alan (b.

Genetic evidence points to an evolu�  tionary divergence between the lineages of humans and the great apes on  the African continent 8-5 million years ago (mya). The earliest fossils  considered to be remains of hominins (members of the human lineage) date  to at least 4 mya in Africa; they are classified as genus Australopithecus.  The next major evolutionary stage, Homo habius, inhabited sub-Saharan  Africa about 2-1.5 mya. Homo habilis appears to have been supplanted  by a taller and more humanlike species, Homo erectus, which lived from  c. 1,700,000 to 200,000 years ago, gradually migrating into Asia and parts  of Europe. Between c. 600,000 and 200,000 years ago. Homo heidelber-  gensis, sometimes called archaic Homo sapiens, lived in Africa, Europe,  and perhaps parts of Asia. Having features resembling those of both H.</p><p>erectus and modern humans, H. heidelbergensis may have been an ances�  tor of modem humans and also of the Neanderthals ( H. neanderthalen-  sis), who inhabited Europe and western Asia from c. 200,000 to 28,000  years ago. Fully modem humans (H. sapiens) seem to have emerged in  Africa only c. 150,000 years ago, perhaps having descended directly from  H. erectus or from an intermediate species such as H. heidelbergensis.</p><p>human factors engineering See ergonomics</p><p>Human Genome Project U.S. research effort initiated in 1990 by  the U.S. Department of Energy and the National Institutes of Health to  analyze the DNA of human beings. The project, intended to be completed  in 15 years, proposed to identify the chromosomal location of every  human GENE, to determine each gene�s precise chemical structure in order  to show its function in health and disease, and to determine the precise  sequence of nucleotides of the entire set of genes (the genome). Another  project was to address the ethical, legal, and social implications of the  information obtained. The information gathered will be the basic refer�  ence for research in human biology and will provide fundamental insights  into the genetic basis of human disease. The new technologies developed  in the course of the project will be applicable in numerous biomedical  fields.

Theo�  ries about the nature of humankind form a part of every culture. In the  West, debate has traditionally centred on whether humans are selfish and  competitive (see Thomas Hobbes; John Locke) or social and altruistic (Karl  Marx, Emile Durkheim). Recent research in genetics, evolutionary biology,  and cultural anthropology suggests that humans may be both, and that  there is a complex interaction between genetically inherited factors  (�nature�) and developmental and social factors (�nurture�). Basic drives  shared with other primates include food, sex, security, play, and social sta�  tus. Gender differences include greater investment in reproduction and  child-rearing among females, hence less risk-taking; and concomitantly  less investment and greater risk-taking among males.

The term came into wide use after World War - II, replacing  the earlier phrase �natural rights,� which had been associated with the  Greco-Roman concept of natural law since the end of the Middle Ages.  As understood today, human rights refer to a wide variety of values and  capabilities reflecting the diversity of human circumstances and history.  They are conceived of as universal, applying to all human beings every�  where, and as fundamental, referring to essential or basic human needs.  Human rights have been classified historically in terms of the notion of  three �generations� of human rights. The first generation of civil and  political rights, associated with the Enlightenment and the English, Ameri�  can, and French revolutions, includes the rights to life and liberty and the  rights to freedom of speech and worship. The second generation of eco�  nomic, social, and cultural rights, associated with revolts against the pre�  dations of unregulated capitalism from the mid-19th century, includes the  right to work and the right to an education. Finally, the third generation  of solidarity rights, associated with the political and economic aspirations  of developing and newly decolonized countries after World War II,  includes the collective rights to political self-determination and economic  development. Since the adoption of the Universal Declaration of Human  Rights in 1948, many treaties and agreements for the protection of human  rights have been concluded through the auspices of the United Nations,  and several regional systems of human rights law have been established.  In the late 20th century ad hoc international criminal tribunals were con�  vened to prosecute serious human rights violations and other crimes in  the former Yugoslavia and Rwanda. The International Criminal Court,  which came into existence in 2002, is empowered to prosecute crimes  against humanity, crimes of genocide, and war crimes.</p><p>human sacrifice Offering of the life of a human being to a god.

It was especially com�  mon among agricultural people (e.g., in the ancient Near East), who  sought to guarantee the fertility of the soil. The Aztecs sacrificed thou�  sands of victims (often slaves or prisoners of war) annually to the sun,  and the Incas made human sacrifices on the accession of a ruler. In ancient  Egypt and elsewhere in Africa, human sacrifice was connected with ances�  tor worship, and slaves and servants were killed or buried alive along with  dead kings in order to provide service in the afterlife. A similar tradition  existed in China. The Celts and Germanic peoples are among the Euro�  pean peoples who practiced human sacrifice.</p><p>humanism In Renaissance Europe, a cultural impulse characterized by  a revival of classical letters, an individualistic and critical spirit, and a  shift of emphasis from religious to secular concerns. It dates to the 14th  century and the poet Petrarch, though earlier figures are sometimes  described as humanists. Its diffusion was facilitated by the universal use  of Latin and the invention of movable type.</p><p>humanistic psychology Twentieth-century movement in psychology,  developed largely in reaction against behaviourism and psychoanalysis, that  emphasizes the importance of values, intentions, and meaning in the com�  pass of the individual. The concept of the �self� is a central focus for  most humanistic psychologists. Architects of the humanistic approach  included Abraham H. Maslow, Carl R. Rogers, and Rollo May (1909-94).  Types of humanistic therapies have included sensory awareness, encoun�  ter groups, existential analysis, Gestalt therapy, logotherapy, and various  transpersonal, human-potential, holistic-health, and addiction-recovery  schools.</p><p>humanities Branches of knowledge that investigate human beings,  their culture, and their self-expression. Distinguished from the physical  and biological sciences and, sometimes, from the social sciences, the  humanities include the study of languages and literatures, the arts, his�  tory, and philosophy. The modem conception of the humanities has roots  in the classical Greek paideia, a course in general education dating from  the 5th century bc that prepared young men for citizenship. It also draws  on Cicero�s humanitas , a program of training for orators set forth in 55  bc. The Renaissance humanists contrasted studia humanitatis (�studies of  humanity�) with studies of the divine; by the 19th century the distinction  was instead drawn between the humanities and the sciences.</p><p>Humanities, National Endowment for the See National  Endowment for the Humanities</p><p>Humber, River ancient Abus River, North Sea inlet, on the eastern  coast of England.

During these journeys he discovered the connection  between the Amazon and Orinoco river systems and surmised that altitude  sickness was caused by lack of oxygen. He studied the oceanic current off  the western coast of South America; it became known as the Humboldt  Current (now the Peru Current). He returned to Europe in 1804. His  research helped lay the foundation for comparative climatology, drew a  connection between a region�s geography and its flora and fauna, and  added to an understanding of the development of the Earth�s crust. In Paris  he used his financial resources to help Louis Agassiz and others launch  careers. In 1829 he traveled to Russia and Siberia and made geographic,  geologic, and meteorologic observations of Central Asia. During the 1830s  he investigated magnetic storms. The last 25 years of his life were spent  writing Kosmos, an account of the structure of the universe as then known.</p><p>Humboldt, (Karl) Wilhelm, baron von (b.

As minister of education (1809), he  raised elementary education standards and was instrumental in founding  Friedrich Wilhelm University (now Humboldt University, or University  of Berlin) in Berlin. Humboldt also contributed greatly to the philosophy  of language, contending that its character and structure express the speak�  er�s culture and individuality and that humans perceive the world through  the medium of language.

May 7, 1711, Edinburgh, Scot.�d. Aug. 25, 1776,  Edinburgh) Scottish philosopher, historian, and economist. He conceived  of philosophy as the inductive, experimental science of human nature. His  first major work, A Treatise of Human Nature (1739-40), explains the ori�  gin of ideas, including the ideas of space, time, and causality, in sense  experience; presents an elaborate account of the affective, or emotional,  aspects of the mind and assigns a subordinate role to reason in this order  (�Reason is, and ought only to be, the slave of the passions�); and  describes moral goodness in terms of �feelings� of approval or disap�  proval that a person has when he considers human behaviour in the light  of the agreeable or disagreeable consequences either to himself or to oth�  ers. The Treatise was poorly received, and late in life Hume repudiated it  as juvenile. He revised Book I of the Treatise as An Enquiry Concerning  Human Understanding (1758); a revision of Book III was published as  An Enquiry Concerning the Principles of Morals (1751). His Dialogues  Concerning Natural Religion (1779), containing a refutation of the argu�  ment from design and a critique of the notion of miracles, was withheld  from publication during his lifetime at the urging of friends. From his  account of the origin of ideas Hume concluded that we have no knowl�  edge of a �self� as the enduring subject of experience; nor do we have  knowledge of any �necessary connection� between causally related  events. Immanuel Kant, who developed his critical philosophy in direct  reaction to Hume, said that Hume had awakened him from his �dogmatic  slumbers.� In Britain, Hume�s moral theory influenced Jeremy Bentham to  adopt utilitarianism. With John Locke and George Berkeley, Hume is  regarded as one of the great philosophers of empiricism.</p><p>Hume, John (b. Jan. 18, 1937, Londonderry, N.Ire.)

A schoolteacher, Hume became a Roman Catholic leader  in the Northern Ireland civil rights movement in the 1960s. He was elected  to the parliaments of Northern Ireland (1969), Europe (1979), and Brit�  ain (1983). A moderate, he condemned the use of violence by the Irish  Republican Army (IRA). In the late 1980s he attempted to persuade the IRA  to abandon the armed struggle against Britain and enter democratic poli�  tics. He risked his personal safety to engage in sometimes secret dialogues  with leaders of Sinn Fein, the IRA�s political wing, and he played a lead�  ing role in negotiating the Good Friday Agreement, the multiparty peace  accord between unionists and nationalists reached in April 1998.

One of the most variable  characteristics of the atmosphere, humidity is an important factor in cli�  mate and weather: it regulates air temperature by absorbing thermal radia�  tion both from the Sun and the Earth; it is directly proportional to the  latent energy available for the generation of storms; and it is the ultimate  source of all forms of condensation and precipitation. Humidity varies  because the water-holding capacity of air is determined by temperature.  When a volume of air at a given temperature holds the maximum amount  of water vapour possible, the air is said to be saturated. Relative humid�  ity is the water-vapour content of the air relative to its content at satura�  tion.

The  variant mixture of these humours in each person determined his �com�  plexion� or temperament and his mental and physical qualities. The ideal  person had the perfectly proportioned mixture of the four fluids; a dis�  proportionate amount of one humour created a personality dominated by  one set of related emotions (e.g., a choleric man was easily angered,  proud, ambitious, and vengeful).</p><p>humpback whale Long-finned baleen whale (.

They are black above, with some white below, and  have large knobs on the head and jaws. The humpback migrates between  polar waters in summer and tropical or subtropical breeding grounds in  winter. It feeds on shrimplike crustaceans, small fish, and plankton. It is  probably the most vocal of all whales (with �songs� of 5-35 minutes) and  one of the most acrobatic (capable of turning a somersault).

Appearing from central Asia after the mid-4th  century, they first overran the Alani, who occupied the plains between the  Volga and Don rivers, and then overthrew the Ostrogoths living between  the Don and Dniester rivers. About 376 they defeated the Visigoths living  in what is now approximately Romania and reached the Danubian fron�  tier of the Roman Empire. As warriors, they inspired almost unparalleled  fear throughout Europe; they were accurate mounted archers, and their  rapid, ferocious charges brought them overwhelming victories. They  extended their power over many of the Germanic peoples of central  Europe and allied themselves with the Romans. By 432 the leadership of  the various groups of Huns had been centralized under a single king, Rua  (Rugila). After his death (434), he was succeeded by his two nephews,  Bleda and Attila. By a peace treaty with the Eastern Roman Empire, the  Romans agreed to double the subsidies they had been paying the Huns;  when they apparently failed to pay the stipulated sums, Attila launched a  heavy assault on the Roman Danubian frontier (441), and other attacks  spread the Huns� control into Greece and Italy. After Attila�s death (453),  his many sons divided up his empire and began a series of costly struggles  with their subjects. The Huns were finally routed in 455 by an alliance of  Gepidae, Ostrogoths, Heruli, and others in a great battle in Pannonia. The  Eastern Roman government then closed the frontier to the Huns, who  gradually disintegrated as a social and political unit.</p><p>Hunan Vhii-'nanV or Hu-nan Province (pop., 2002 est.: 66,290,000),  central China.

It began when Edward III invaded Flanders  in 1337 in order to assert his claim to the French crown. Edward won a  major victory at the Battle of Crecy (1346); after his son Edward the Black  Prince managed to capture John II at the Battle of Poitiers (1356), the  French were obliged to surrender extensive lands under the treaties of  Bretigny and Calais (1360). When John II died in captivity, his son Charles  V refused to respect the treaties and reopened the conflict, putting the  English on the defensive. After Charles V�s death in 1380 both countries  were preoccupied with internal power struggles, and the war lapsed into  uncertain peace. In 1415, however, Henry V decided to take advantage of  civil war in France to press English claims to the French throne (see Battle  of Agincourt). By 1422, the English and their Burgundian allies controlled  Aquitaine and all France north of the Loire, including Paris. A turning  point came in 1429, when Joan of Arc raised the English siege of Orleans.  The French king Charles VII conquered Normandy and then retook Aquita�  ine in 1453, leaving the English in possession only of Calais. The war  laid waste to much of France and caused enormous suffering; it virtually  destroyed the feudal nobility and thereby brought about a new social  order. By ending England�s status as a power on the continent, it led the  English to expand their reach and power at sea.</p><p>Hung Hsiu-ch'uan See Hong Xiuquan  Hung-shan culture See Hongshan culture  Hung-shui River See Hongshui River  Hung T'ai-chi See Hongtaiji  Hung-tse Hu See Hongze Lake  Hung-wu emperor See Hongwu emperor</p><p>Hungarian language Finno-Ugric language of Hungary, with sub�  stantial minority populations in Slovakia, Transylvania in Romania, and  northern Serbia.

Religion: Christianity (mostly  Roman Catholic; also Protestant). Cur�  rency: forint. The Great Alfold (Great Hun�  garian Plain), with fertile agriculture land,  occupies nearly half of the country. Hunga�  ry�s two most important rivers are the Danube and the Tisza. Lake Bala�  ton, in the Transdanubian highlands, is the largest lake in central Europe.  Forests cover nearly one-fifth of the land. Hungary is one of the more  prosperous countries of eastern Europe and a major world producer of  bauxite. A conversion from a socialist to a free-market economy was  begun in the late 1980s. Hungary is a multiparty republic with one leg�  islative house; the chief of state is the president, and the head of govern�  ment is the prime minister. The western part of the country was  incorporated into the Roman Empire in 14 bc. The Magyars, a nomadic  people, settled in the Great Alfold in the late 9th century. Stephen I,  crowned in 1000, Christianized the country and organized it into a strong  and independent state. Invasions by the Mongols in the 13th century and  by the Ottoman Empire in the 15th century devastated the country, and  by 1568 the territory of modern Hungary was divided into three parts:  Royal Hungary had fallen to the Habsburgs; Transylvania had gained  autonomy in 1566 under the Ottoman Turks; and the central plain  remained under Ottoman control until the late 17th century, when the  Austrian Habsburgs took over. Hungary declared its independence from  Austria in 1849, and in 1867 the Dual Monarchy of Austria-Hungary was  established. Its defeat in World War I (1914-18) resulted in the dismem�  berment of Hungary, leaving it only those areas in which Magyars pre�  dominated. In an attempt to regain some of this lost territory, Hungary  cooperated with the Germans against the Soviet Union during World War  II (1939-45). After the war a pro-Soviet provisional government was  established, and in 1949 the Hungarian People�s Republic was formed.  Opposition to this Stalinist regime broke out in 1956 but was suppressed  (see Hungarian Revolution). Nevertheless, from 1956 to 1988 communist  Hungary grew to become the most tolerant of the Soviet-bloc nations of  Europe. It gained its independence in 1989 and soon attracted the largest  amount of direct foreign investment in eastern and central Europe. It  joined NATO in 1999 and the European Union in 2004.</p><p>Hunkar jskelesi. Treaty of (1833) Alliance between the Ottoman  Empire and Russia, signed at the village of Hunkar iskelesi (Unkiar Ske-  lessi), near Istanbul. In return for Russian military aid, the Ottoman sul�  tan, Mahmud II, agreed to a secret article in their mutual defense treaty  that closed the Dardanelles Strait to any foreign vessels of war except  those of Russia. The treaty made the Ottoman Empire a virtual protector�  ate of Russia. When other countries became suspicious of the agreement,  Russia abandoned its Dardanelles privileges in 1841.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Hunkers and Barnburners &#x25BA; Huntington I 911</p><p>Hunkers and Barnburners Two factions of the New York state  Democratic Party in the 19th century. The party split over slavery in the  1840s. The conservative Hunkers (so called by their opponents as those  who �hunkered� or �hankered� after political office), led by William  Marcy, favoured the annexation of Texas and denounced antislavery agi�  tation. The radical and reformist Barnburners (so called by their oppo�  nents as those who burned the bam to get rid of the rats), led by Martin  Van Buren, opposed slavery�s extension into new territories. At the 1848  Democratic national convention, the Barnburners joined the Free Soil  Party, nominating Van Buren for president. In the 1850s some Barnburn�  ers returned to the Democratic Party while others joined the new Repub�  lican Party.</p><p>Hunt, H(aroldson) L(afayette) (b. Feb. 17, 1889, Ramsey, Ill.,  U.S.�d. Nov. 29, 1974, Dallas, Texas) U.S. oilman. Hunt purchased a  tract of land in eastern Texas in 1930 that became one of the richest oil�  fields in the U.S. He continued his shrewd investments through his Hunt  Oil Co. (founded 1936), which grew into the largest independent oil and  gas producer in the country. In the 1960s his company exploited vast oil  deposits in Libya. He also invested in publishing, cosmetics, pecan farm�  ing, and health food. He promoted his ultraconservative views on his own  radio programs and newspaper column in the 1950s. Two of his sons, N.  Bunker and W. Herbert, tried unsuccessfully to corner the world silver  market in 1980, causing its near collapse.</p><p>Hunt, R. Timothy (b. Feb. 19, 1943, Neston, Cheshire, Eng.) British  scientist. After receiving a Ph.D. from the University of Cambridge in  1968, he conducted research at the Albert Einstein College of Medicine  in New York and in 1990 joined the Imperial Cancer Research Fund (now  Cancer Research UK) in London. In the early 1980s, using sea urchins,  he discovered cyclins, proteins that play a key role in regulating different  phases of the cell cycle. His work led to the discovery of cyclins in humans  and proved important in the field of tumour diagnostics. Hunt shared a  Nobel Prize with Leland H. Hartwell and Sir Paul M. Nurse in 2001.</p><p>Hunt, Richard Morris (b. Oct. 31, 1827, Brattleboro, Vt., U.S.�d.  July 31, 1895, Rewport, R.I.) U.S. architect. He studied in Europe from  1843 to 1854, becoming the first U.S. architecture student at the Ecole  des Beaux-Arts in Paris. He returned to the U.S. to establish the Beaux-  Arts style there. His work was eclectic, ranging from ornate early French  Renaissance to monumental Classicism to a picturesque villa style. He  worked on the extension of the U.S. Capitol and designed the Tribune  building in New York City (1873; since destroyed) and the facade of the  Metropolitan Museum of Art (1900-02), also in New York. Among the  mansions he designed for the new commercial aristocracy is the Break�  ers in Newport, R.I. (1892-95), which was created in an opulent Renais�  sance style for the Vanderbilts. Hunt was a founder of the American  Institute of Architects.</p><p>Hunt, William Holman (b. April 2, 1827, London, Eng.�d. Sept. 7,  1910, London) British painter and cofounder of the Pre-Raphaelite Broth�  erhood. He attended the Royal Academy schools and achieved his first  public success with The Light of the World (1854). His paintings are char�  acterized by hard colour, minute detail, and an emphasis on moral or social  symbolism; their moral earnestness made them extemely popular in Vic�  torian England. He spent two years in Syria and Palestine painting bib�  lical scenes, such as The Scapegoat (1855), depicting the outcast animal  on the shores of the Dead Sea. His autobiographical Pre-Raphaelitism and  the Pre-Raphaelite Brotherhood (1905) is the basic sourcebook of the  movement.</p><p>Hunter, John (b. Feb. 13, 1728, Long Calderwood, Lanarkshire,  Scot.�d. Oct. 16, 1793, London, Eng.) British surgeon. He never  attempted to become a medical doctor but assisted in the preparation of  dissections for a course of anatomy taught by his brother William Hunter.  In the early 1770s he began giving his own lectures on surgery, and in  1776 he was named surgeon extraordinary to George III. He carried out  many highly diverse and important studies in comparative biology,  anatomy, physiology, and pathology and is considered the founder of  pathological anatomy in Britain. He was an important influence on Edward  Jenner.</p><p>Hunter, William (b. May 23, 1718, Long Calderwood, Lanarkshire,  Scot.�d. March 30, 1783, London, Eng.) British obstetrician, educator,  and medical writer. The brother of John Hunter, he studied medicine at  the University of Glasgow and became a licensed physician in London  in 1756. He introduced the French practice of providing individual medi�</p><p>cal students with cadavers for dissection to Britain. After 1756 his medi�  cal practice was devoted principally to obstetrics; he became the most  successful specialist of his day and was made physician extraordinary to  Queen Charlotte in 1762. His work did much to remove obstetrics from  the purview of midwives and establish it as an accepted branch of medi�  cine.</p><p>Hunter River River, eastern New South Wales, Australia. Rising in the  Mount Royal Range of the Eastern Highlands, it flows southwest through  the Glenbawn Reservoir and past Denman. There, joined by its major  tributary, the Goulburn River, the Hunter turns southeast, entering the Tas�  man Sea at Newcastle after a course of 287 mi (462 km). Its estuary forms  one of the state�s largest harbours.</p><p>Hunters' Lodges Secret organization of Canadian rebels and U.S.  adventurers dedicated to freeing Canada from British colonial rule. It was  formed after the failure of the 1837 rebellion and was concentrated in the  northern U.S. border states. In 1838 two attempts to invade Upper Canada  (now Ontario) were stopped by local British Canadian militia. Minor bor�  der raids continued until Pres. Martin Van Buren ordered the lodges dis�  banded in accordance with U.S. neutrality laws.</p><p>hunting Pursuit of game animals, principally as sport. To early humans  hunting was a necessity, and it remained so in many societies until  recently. The development of agriculture made hunting less necessary as  a sole life support, but game was still pursued in order to protect crops,  flocks, or herds, as well as for food. Weapons now commonly used in  hunting include the rifle, shotgun, and the bow and arrow, and methods  include stalking, still-hunting (lying in wait), tracking, driving, and call�  ing. Dogs are sometimes employed to track, flush, or capture prey. In  Europe much of the land once hunted upon was owned by the aristocracy,  and gamekeepers were employed to regulate the amount of game that  could be hunted in a given area. By the 1800s the land hunted upon was  not or had never been privately owned, and there began to develop a  �tragedy of the commons,� in that no one hunter had any motive to limit  the number of animals killed; certain species were hunted to, or very close  to, extinction. To counter this development, ethical codes were established  that give the quarry a fair chance to escape; attempts were made to mini�  mize the suffering of wounded game; and game laws, licensing, and lim�  ited hunting seasons were established to protect game stocks. For instance,  a modem license may authorize a hunter to kill only two deer during the  brief season for deer, and he or she must present a kill to a game warden  who will then document and tag the animal. There are often penalties and  fines for being found with an animal that is not so marked.</p><p>hunting and gathering society Any human society that depends  on hunting, fishing, or the gathering of wild plants for subsistence. Until  c. 8,000 years ago, all peoples were foragers of wild food. Many forag�  ing peoples continued to practice their traditional way of life into the 20th  century, but today all such peoples have developed extensive contacts with  settled groups. In the traditional hunting-and-gathering society, social  groups were small, usually made up of either individual family units or a  number of related families collected together in a band. The diet was well  balanced and ample, and food was shared. The men usually did the hunt�  ing while the women gathered plants and did most domestic chores. The  remainder of the time was spent on social and religious activities.</p><p>Huntington, Collis P(otter) (b. Oct. 22, 1821, Harwinton, Conn.,  U.S.�d. Aug. 13, 1900, Raquette Lake, N.Y.) U.S. railroad magnate. He  worked as a peddler before becoming a prosperous merchant in Oneonta,  N.Y. In the gold rush year of 1849, he moved to Sacramento, Calif., and  joined Mark Hopkins in a firm that specialized in miners� supplies. In the  late 1850s he became interested in a plan to link California with the east�  ern U.S. by rail. In 1861 he joined Hopkins, Leland Stanford, and Charles  Crocker (1822-1888)�a group later known as the �Big Four��to form  the Central Pacific Railroad. During its construction (1863-69), Hunting-  ton lobbied for the company in the east, securing financing and favour�  able legislation from the federal government. In 1865 the Big Four formed  the Southern Pacific Railroad. In 1869 Huntington bought the Chesapeake  and Ohio Railway, which he later extended to link with the Southern  Pacific, forming the first transcontinental railroad. He became president  of the Southern Pacific-Central Pacific system in 1890.</p><p>Huntington, Samuel P(hillips) (b. April 18, 1927, New York, N.Y.,  U.S.) U.S. political scientist.

Its major economic assets are oil  wells and refineries.</p><p>Huntington chorea Relatively rare, hereditary neurological disease  that is characterized by irregular and involuntary movements of the  muscles. Huntington chorea is caused by a genetic mutation that causes  degeneration of neurons in a part of the brain that controls movement.  Symptoms usually appear between ages 35 and 50. They begin with occa�  sional jerking or writhing movements, which are absent during sleep, and  progress to random, uncontrollable, and often violent twitchings and jerks.  Symptoms of mental deterioration begin later and include memory loss,  dementia, bipolar disorder, or schizophrenia. There is no effective therapy  or cure, and the disease invariably proves fatal. A child of a person with  Huntington chorea has a 50% chance of developing the disease.</p><p>Huntsman, Benjamin (b. 1704, Holland�d. June 21, 1776, Shef�  field, Yorkshire, Eng.)

His new pro�  cess yielded cast steel more uniform in composition and freer from impu�  rities than any previously produced. Sheffield steelmakers used the  crucible process to achieve worldwide dominance in the production of  tool and other high-quality steels.</p><p>Huntsville City (pop., 2000: 158,216), northern Alabama, U.S. Origi�  nally called Twickenham, it was the first community in Alabama to be  granted a city charter, in 1811.

With aid from Venice and the pope, he mounted a campaign against  the Turks (1441-43) that broke the Ottoman Empire�s hold on the Bal�  kan states, though he was defeated in a Turkish counterattack at the Battle  of Varna (1444). In 1446 he was elected regent for the young king, Las-  zlo V, and he served as governor of the kingdom of Hungary 1446-52.  In 1456 he raised the Turkish siege of Belgrade before dying of disease.  For stopping the supposedly invincible Turkish armies, he is considered  a Hungarian national hero.</p><p>Huon \'hyu-3n\ River River, southern Tasmania, Australia.

Runners must remain in assigned lanes throughout a race,  and, though they may knock hurdles down while running over them, they  may do so only with a leg or foot, not a hand. Modern hurdlers use a  sprinting style between hurdles, display an exaggerated forward lean  while clearing the hurdle, and then bring the trailing leg through at nearly  a right angle to the body, which enables them to continue forward with�</p><p>out breaking stride after clearing the hurdle.

As rector of the university from 1402, he became leader of a  reform movement that criticized the corruption of the Roman Catholic  clergy. The movement was threatened when Wycliffe�s teachings were  condemned by the church, and Hus�s position was further undermined by  his stand in the power struggles among rival popes. He was excommu�  nicated in 1411 but continued to preach. Renewed sale of indulgences by  the antipope John XXIII earned Hus�s criticism, which in turn led to a  revival of the case of heresy against him. He was invited to the Council  of Constance to explain his views; though promised safe conduct, he was  arrested, tried for heresy, and burned at the stake.

Several hussar regiments of the British army were con�  verted from light dragoons in the 19th century; they survive today as  armoured units.</p><p>Hussein \hu-'san\ in full Hussein ibn Talal (b. Nov. 14, 1935,  Amman, Transjordan�d. Feb. 7,</p><p>1999, Amman, Jordan) King of Jor�  dan (1952-99). Educated in Britain,  he succeeded his father, King Talal,  while still in his teens. His country�s  precarious geographic and economic  position and the many Palestinians  living there (whom he, unlike other  Arab rulers, offered citizenship and  a passport) forced him to chart a cau�  tious course in international rela�  tions. Though he earned on secret  talks with all Israeli leaders except  Menachem Begin, he joined other  Arab nations against Israel in the Six-  Day War (1967). When the Jordan-  based Palestine Liberation Organiza�  tion (PLO) threatened his reign after  defeat in that conflict, Hussein  expelled it (1971). Thereafter he  sought to repair relations with the  PLO without unduly antagonizing  Israel or the U.S. He surrendered Jor�  dan�s claim to the West Bank in 1988, ceding it to the PLO. He consid�  ered his 1994 peace treaty with Israel his crowning achievement.</p><p>Husserl Vhu-so-roL, Edmund (b. April 8, 1859, Prossnitz, Moravia,  Austrian Empire�d. April 27, 1938,</p><p>Freiburg im Breisgau, Ger.) German  philosopher, founder of phenomenol�  ogy. He received a doctoral degree in  mathematics at the University of  Vienna in 1882. From 1883 to 1886  he studied with Franz Brentano,  whose descriptive psychology  prompted Husserl to reflect on the  psychological sources of basic math�  ematical concepts. He lectured at the  University of Halle from 1887 to  1901. His Logical Investigations  (1901) employed a method he called  �phenomenological,� consisting of  an analysis of experienced reality  exactly as it presents itself to con�  sciousness. He developed the  method in Ideas (1913) and other  works written while teaching at the  University of Gottingen (1901-16);  its fundamental methodological principle was what he called phenomeno�  logical, or �eidetic,� reduction, which focuses the philosopher�s attention  on uninterpreted experience and the quest, thereby, for the essences of  things. Because it is also reflection on the functions by which essences  become conscious, the reduction reveals the ego for which everything has  meaning. In 1916 Husserl accepted a professorship at the University of  Freiburg, where Martin Heidegger was one of his students; when Husserl  retired in 1928, Heidegger succeeded to his chair. After 1933, when the</p><p>Edmund Husserl, c. 1930.</p><p>ARCHIV FUR KUNST UND GESCHICHTE, BERUN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>914 I Hussite &#x25BA; Huxley</p><p>Nazis seized power in Germany, Husserl was excluded from the univer�  sity because of his Jewishness. His work was enormously influential in  the subsequent development of Continental philosophy and in other fields,  including the social sciences and psychoanalytic theory.</p><p>Hussite Vho-.slt, 'hu-,slt\ Member of a group of 15th-century Bohemian  religious reformers, followers of Jan Hus. After Hus�s death in 1415, the  Hussites broke with Rome. In addition to giving communion in both bread  and wine, they supported freedom of preaching, poverty of the clergy,  civil punishment of notorious sinners, and expropriation of church prop�  erty. Many were nobles and knights, and a papal crusade against them  failed in 1431. During peace negotiations in 1433 the Hussites split into  two factions, the moderate Utraquists and the radical Taborites. The  Utraquists joined the Catholics and defeated the Taborites at the battle of  Lipany in 1434; they survived schisms until 1620, when they were  absorbed by the Catholics. Another segment of Hussites, Unitas Fratrum,  set up an independent organization in 1467 and lasted until the Counter-  Reformation. In 1722 a group of Hussites fled Moravia and settled on the  estate of Count Nikolaus Ludwig von Zinzendorf (1700-1760) in Sax�  ony, establishing the community of Herrnhut and founding the Moravian  CHURCH.</p><p>Huston Vhyii-stonV, John (b. Aug. 5, 1906, Nevada, Mo., U.S�d. Aug.  28, 1987, Middletown, R.I.) U.S. film director and screenwriter. The son  of Walter Huston, he was briefly a boxer, a Mexican cavalry officer, and  a reporter before becoming a scriptwriter. His first work as a director, The  Maltese Falcon (1941), began an illustrious career studded with film clas�  sics: The Treasure of the Sierra Madre (1948, Academy Awards for best  director and screenplay), Key Largo (1948), The Asphalt Jungle (1950),  The African Queen (1951), Moulin Rouge (1952), The Night of the Iguana  (1964), The Man Who Would Be King (1975), Prizzi�s Honor (1985), and  The Dead (1987). He wrote screenplays for many of his own films and  for others such as Jezebel (1938), Juarez (1939), and High Sierra (1941).  He also worked as an actor, notably in Chinatown (1974). His daughter  Anjelica (b. 1951) was an accomplished actress, earning an Academy  Award for her performance in Prizzi�s Honor (1985).</p><p>Huston, Walter orig. Walter Houghston (b. April 6, 1884, Tor�  onto, Ont., Can.�d. April 7, 1950, Beverly Hills, Calif., U.S.) Canadian-  born U.S. actor. He made his stage debut in his native Toronto in 1902  and his New York debut in 1905. He and his second wife were a popular  vaudeville song-and-dance team (1909-24). On Broadway he won praise  in Desire Under the Elms (1924), Dodsworth (1934; film, 1936), and  Knickerbocker Holiday (1938), in which he sang �September Song.� He  appeared in over 50 films, including Abraham Lincoln (1930), Rain  (1932), and The Treasure of the Sierra Madre (1948, Academy Award),  directed by his son John Huston.</p><p>Hutchins, Robert Maynard (b. Jan. 17, 1899, Brooklyn, N.Y.,  U.S.�d. May 17, 1977, Santa Barbara, Calif.) U.S. educator and foun�  dation president. He attended Oberlin College and graduated from Yale  University (A.B., 1921) and Yale Law School (LL.B., 1925), becoming  dean of Yale Law School in 1927. At the University of Chicago as presi�  dent (1929-45) and chancellor (1945-51), he encouraged liberal educa�  tion based on the study of the great books of the Western tradition,  deplored any tendency toward vocationalism, and dismantled the inter�  collegiate athletic program. Hutchins later headed various foundations,  including the Ford Foundation. He served as chairman of the board of  editors of Encyclopedia Britannica (1943-74) and edited the 54-volume  Great Books of the Western World (1952). He expounded his views on  education in Higher Learning in America (1936).</p><p>Hutchinson, Anne orig. Anne Marbury (baptized July 20, 1591,  Alford, Lincolnshire, Eng.�d. August or September 1643, Pelham Bay,  N.Y.) Anglo-American religious leader. In 1612 she married William  Hutchinson, and they followed John Cotton to the Massachusetts Bay  Colony in 1634. She organized weekly meetings of Boston women to dis�  cuss recent sermons and to express their own theological views. Before  long, ministers and magistrates were attracted to her sessions, at which  she criticized the narrow Puritan orthodoxy and espoused a �covenant of  grace.� Her opponents accused her of believing that God�s grace had freed  Christians from the need to observe established moral precepts. Tried for  �traducing the ministers,� she was sentenced to banishment; refusing to  recant, she was excommunicated. In 1638 she and her husband established  a colony at Aquidneck Island, which became part of Rhode Island.</p><p>Hutchinson, Thomas (b. Sept. 9, 1711, Boston, Mass.�d. June 3,  1780, London, Eng.) American colonial administrator. The son of a  wealthy Boston merchant, he pursued business ventures before serving in  local and provincial legislatures (1737�49) and as a delegate to the Albany  Congress. He served as lieutenant governor (1758-71) and as chief jus�  tice of the state Superior Court (1760-69). As governor (1771-74), he  strictly enforced British rule. After he was accused of initiating the hated  Stamp Act, a mob attacked his home, and he barely escaped with his life.  His insistence that a shipment of tea be landed in Boston led to the Bos�  ton Tea Party. He was replaced as governor by Gen. Thomas Gage.</p><p>Hutchinson Family U.S. singing group, significant figures in the  development of a native popular music tradition. Bom and raised in Mil�  ford, N.H., the Hutchinson brothers Judson (1817-59), John (1821-1908),  and Asa (1823-84) and sister Abby (1829-92) formed a quartet and began  giving concerts around New England in 1841. In contrast to the prevail�  ing sentimental and minstrel songs of the period, their songs embraced  political causes, including woman suffrage, prohibition of alcohol, and  opposition to the Mexican War. They sang at many antislavery rallies,  including a Boston rally that drew 20,000 people. With some members  replaced by other family members, the family continued to tour into the  1880s.</p><p>Hutterite \ , h3-t3- l rlt\ Member of the Hutterite Brethren, an Anabaptist  sect that takes its name from its Austrian founder, Jakob Hutter, who was  burned as a heretic in 1536. His followers modeled themselves on the  early church in Jerusalem by holding their goods in common. Persecuted  in Moravia and the Tirol, they moved eastward to Hungary and the  Ukraine. In the 1870s many emigrated to the U.S. and settled in South  Dakota. The society still exists in the western U.S. and Canada, where it  has colonies of 60-150 members, who operate collective farms. Hutter-  ites are pacifists who take no part in politics and remain separate from  outside society.</p><p>Hutton, James (b. June 3, 1726, Edinburgh, Scot.�d. March 26, 1797,  Edinburgh) Scottish geologist, chemist, and naturalist. After short careers  in law and medicine, he followed his interest in chemistry and developed  an inexpensive manufacturing process for sal ammoniac. He settled in  Edinburgh (1768) to pursue a life of science. In two papers presented in  Edinburgh in 1785 (published 1788), he elaborated his theory of unifor-  mitarianism. Its ability to explain the Earth�s geologic processes without  reference to the Bible and its emphasis on an immensely long, cyclical  process of erosion, deposition, sedimentation, and volcanic upthrust were  revolutionary.</p><p>Hutu Bantu-speaking people of Rwanda and Burundi, with a large refu�  gee population in Congo (Kinshasa). Numbering about 9.5 million, the  Hutu comprise the vast majority in both Rwanda and Burundi but were  traditionally subject to the Tutsi, who under German and Belgian colonial  regimes succeeded in cultivating a lord-vassal relationship. The two cul�  tures are deeply intertwined; both speak Rwanda and Rundi and adhere  to similar religious beliefs (traditional and Christian). The Tutsi remained  dominant in Rwanda until 1961, when the Hutu expelled most of them  and took over the government. After an unsuccessful Hutu coup attempt  in Burundi in 1965, that country�s Hutu remained subordinate under a  Tutsi-dominated military government. Violent clashes occurred in  Burundi in 1972, 1988, and 1993 and in Rwanda in 1990 and 1994-96,  the later including a Hutu-initiated  genocidal campaign in which more  than a million people were killed and  1-2 million fled to refugee camps in  Zaire (now Congo) and Tanzania.</p><p>Huxley, Aldous (Leonard) (b.</p><p>July 26, 1894, Godaiming, Surrey,</p><p>Eng.�d.

June 22, 1887, London, Eng.�d. Feb.  14, 1975, London) British biologist, philosopher, and author. He was a  grandson of T.H. Huxley and brother of Aldous Huxley. His research on  hormones, developmental processes, ornithology, and ethology influenced  the modern development of embryology, classification, and studies of  behaviour and evolution. He applied his scientific knowledge to social  and political problems, formulating an ethical theory of �evolutionary  humanism.� His many books written for the general public, including The  Science of Life (1931; with H.G. Wells), were widely read. He served as  the first director-general of UNESCO (1946-48).</p><p>Huxley, T(homas) H(enry) (b. May 4, 1825, Ealing, Middlesex,  Eng.�d. June 29, 1895, Eastbourne, Sussex) British biologist. The son  of a schoolmaster, he earned a medical degree. After working as a sur�  geon on a surveying expedition in the South Pacific (1846-50), during  which he carried out extensive studies of marine organisms, he taught for  many years at the Royal School of Mines in London (1854-85). In the  1850s he established his reputation with his important papers on animal  individuality, certain mollusks, the methods of paleontology, the methods  and principles of science and science education, the structure and func�  tions of nerves, and the vertebrate skull. He was one of the earliest and  strongest supporters of Darwinism; his 1860 debate with Bishop Samuel  Wilberforce gained widespread attention. In the 1860s Huxley did valu�  able work in paleontology and classification, especially classification of  birds. Later in life he turned to theology; he is said to have coined the  word agnostic to describe his views.</p><p>Few scientists have been as influen�  tial over such a wide field of scien�  tific development and as effective in  the total movement of thought and  action within their own generation.</p><p>Huygens Vhl-ganz, 'hoi-gonzV  Christiaan or Christian  Huyghens (b.

It formed the  basis for training an elite society of young warriors known as the hwarang,  who were instrumental in unifying Korea under the Silla dynasty (668-  935). Their moral code, derived from Buddhism and Confucianism, empha�  sized loyalty to the king, filial piety, faithfulness to friends, courage in  battle, and the evil of indiscriminate killing. The hwarang were disbanded  during the Choson dynasty (1392-1910), but interest in the code revived  in the late 20th century with a style of Korean martial arts known as  hwarangdo.</p><p>hyacinth Any of the approximately 30 species of bulbous ornamental  herbaceous plants that make up the genus Hyacinthus (lily family), native  primarily to the Mediterranean region and tropical Africa. The common  garden hyacinths are derived from H. orientalis. Most species have nar�  row, untoothed leaves at the base of the plant and fragrant flowers (usu�  ally blue, but sometimes pink, white, or other colors in cultivated  varieties) borne in a cluster at the top of the leafless stems. See also grape  HYACINTH.</p><p>Hyacinthus V.hl-o-'sin-thosX In Greek mythology, a young man of great  beauty who attracted the love of Apollo.

The parents may be of two different species, genera, or  (rarely) families. The terms �mongrel� and �crossbreed� refer usually to  animals or plants resulting from a cross between two races, breeds, strains,  or varieties of the same species. Because of basic biological incompat�  ibilities, sterile hybrids (those that cannot produce living young) such as  the mule (a hybrid between a jackass and a mare) commonly result from  crosses between species. Some species hybrids, however, are fertile and  can be sources for the formation of new species. Many economically or  aesthetically important cultivated plants (e.g., bananas, coffee, peanuts,  dahlias, roses, bread wheats, alfalfa, etc.) originated through natural or  artificially induced hybridization. Hybridization is important biologically  because it increases necessary genetic variation within a species.</p><p>Hyde, Edward See Earl of Clarendon</p><p>Hyder Ali Vhl-dor-a-'leV (b. 1722, Budikote, Mysore, India�d.

Originally part of the kingdom of Golconda, it was brought into the  Mughal Empire in 1687. The independent kingdom of Hyderabad was  founded by Nizam ul-Mulk in 1724. In 1798 it was placed under British  protection, although the nizams (rulers) continued to rule over their  princely state. At Indian partition in 1947, the nizam chose to resume  Hyderabad�s independent status, but India invaded the state (1948) and  took control. The area is now divided among the states of Andhra Pradesh,  Karnataka, and Maharashtra.</p><p>hydra Any of 20-30 species of freshwater cnidarians (genus Hydra).  The POLYP-type body is a thin, usually translucent tube that measures up  to slightly more than 1 in. (25 mm) long. Food is ingested and wastes are  ejected from the open, tentacled end. Individuals are usually hermaphro�  ditic (see hermaphroditism). Reproduction by budding is also common. Spe�  cies differ in colour, tentacle length and number, and gonad position and  size. All hydras feed on other small invertebrates (e.g., crustaceans).</p><p>hydrangea \hl-'dran-j3\ Any of approximately 23 species of erect or  climbing woody shrubs that make up the genus Hydrangea (family  Hydrangeaceae). It is native to the Western Hemisphere and eastern Asia.  Several species are grown in greenhouses and gardens for their showy,  usually ball-like flower clusters. Cultivated varieties of the French hydran�  gea, or hortensia H. macrophylla, bear large globular flower clusters in  various colours; they are the florist�s hydrangeas.</p><p>hydraulic jump Sudden change in water level, analogous to a shock  wave, commonly seen below weirs and sluice gates where a smooth  stream of water suddenly rises at a foaming front. The fact that the speed  of water waves varies with wavelength and with amplitude leads to a wide  variety of effects. Tidal bores, which may be observed on some estuar�  ies, are large-scale examples. See also Bernoulli's principle.</p><p>hydraulic press Machine consisting of a cylinder fitted with a piston  (see piston and cylinder) that uses liquid under pressure to exert a com�  pressive force upon a stationary anvil or baseplate. The liquid is forced  into the cylinder by a pump. The hydraulic press is widely used in indus�  try for forming metals and for other tasks where a large force is required.  It is manufactured in a wide variety of styles and sizes and in capacities  ranging from 1 ton (0.9 metric ton) or less to 10,000 tons (9,000 metric  tons) or more. See also punch press.</p><p>hydraulics Branch of science concerned with the practical applications  of fluids, primarily liquids, in motion. It is related to fluid mechanics, which  in large part provides its theoretical foundation. Hydraulics deals with  such matters as the flow of liquids in pipes, rivers, and channels and their  confinement by dams and tanks. Some of its principles apply also to gases,  usually when variations in density are relatively small. The scope of  hydraulics extends to such mechanical devices as actuators and control  systems. See also Bernoulli's principle, Pascal's law, pump.</p><p>hydride Vhl-.dridV Inorganic compound of hydrogen with another ele�  ment. Three common types are differentiated by their bonding. In saline  (ionic) hydrides (see ionic bond), the hydrogen is an anion, H - , and  behaves like a halogen. Saline hydrides such as sodium hydride (NaH)  and calcium hydride (CaH 2 ) react vigorously with water, giving off hydro�  gen gas (H 2 ), and are used as portable sources of it. Metallic hydrides,  such as titanium hydride (TiH 2 ), are alloylike materials (see alloy) with  some properties of metals, such as luster and electrical conductivity. Cova�  lent hydrides (see covalent bond) are mostly compounds of hydrogen and  nonmetallic elements; they include water, ammonia, hydrogen sulfide  (H 2 S), and methane. In polymeric hydrides, the hydrogen forms bridges</p><p>between other atoms (e.g., hydrides of boron and aluminum). Those  hydrides give off large amounts of energy when burned and may be use�  ful as rocket fuels.</p><p>hydrocarbon Any of a class of organic compounds composed only of  carbon and hydrogen. The carbon atoms form the framework, and the  hydrogen atoms attach to them. Hydrocarbons, the principal constituents  of petroleum and natural gas, serve as fuels, lubricants, and raw materials  for production of plastics, fibres, rubbers, solvents, explosives, and indus�  trial chemicals. All burn to carbon dioxide and water with enough oxygen  or to carbon monoxide without it. The two major categories are aliphatic,  with the carbon atoms in straight or branched chains or in nonaromatic  rings, and aromatic (see aromatic compound). Aliphatic compounds may  be saturated (paraffins) or, if any carbon atoms are joined by double or  triple bonds, unsaturated (e.g., olefins, alkenes, alkynes). All but the sim�  plest hydrocarbons have isomers (see isomerism). Ethylene, methane, acety�  lene, benzene, toluene, and naphthalene are hydrocarbons.</p><p>hydrocephalus N.hl-dro-'se-fo-losV Accumulation of cerebrospinal fluid  (CSF) in the ventricles (cavities) of the brain. Hydrocephalus is caused  by overproduction of CSF, congenital blockage that prevents drainage (see  neural tube defect), or complications of head injuries or infections. Nor�  mally, CSF circulates through the brain and spinal cord and drains into  the circulation. In infants and young children, hydrocephalus causes the  brain and skull to enlarge because the fontanels have not yet closed.  Without surgery to divert the excess fluid into the blood or abdomen,  accumulating fluid eventually compresses the brain, causing convulsions,  mental retardation, and death.</p><p>hydrochemistry See chemical hydrology</p><p>hydrochloric acid or muriatic acid Solution in water of hydrogen  chloride (HC1), a gaseous inorganic compound. It is a strong acid, virtu�  ally completely dissociated (see dissociation) into hydronium cations  (H 3 0 + ) and chloride anions (Cl - ), and is corrosive and irritating. The acid  reacts with most metals, to produce hydrogen and the metal�s chloride,  and with oxides, hydroxides, and many salts. It is used extensively in indus�  trial processing of metals and concentrating of some ores; in boiler scale  removal, food processing, metal cleaning, and pickling; and as a chemi�  cal intermediate, laboratory reagent, and alcohol denaturant (see ethanol).  Hydrochloric acid is present in the stomach�s gastric juice and is involved  in the devlopment of peptic ulcers.</p><p>hydroelectric power Electricity produced from generators driven by  water turbines that convert the energy in falling or fast-flowing water to  mechanical energy. Water at a higher elevation flows downward through  large pipes or tunnels (penstocks). The falling water rotates turbines,  which drive the generators, which convert the turbines� mechanical energy  into electricity. The advantages of hydroelectric power over such other  sources as fossil fuels and nuclear fission are that it is continually renew�  able and produces no pollution. Norway, Sweden, Canada, and Switzer�  land rely heavily on hydroelectricity because they have industrialized  areas close to mountainous regions with heavy rainfall. The U.S., Russia,  China, India, and Brazil get a much smaller proportion of their electric  power from hydroelectric generation. See also tidal power. See illustration  opposite on following page.</p><p>hydrogen Lightest chemical element, chemical symbol H, atomic num�  ber 1. A colourless, odourless, tasteless, flammable gas, it occurs as the  diatomic molecule H 2 . Its atom consists of one proton (the nucleus) and  one electron; the isotopes deuterium and tritium have an additional one and  two nuclear neutrons, respectively. Though only the ninth most abundant  element on Earth, it represents about 75% of all matter in the universe.  Hydrogen was formerly used to fill airships; nonflammable helium has  replaced it. It is used to synthesize ammonia, ethanol, aniline, and metha�  nol; to treat petroleum fuels; as a reducing agent (see reduction) and to  supply a reducing atmosphere; to make hydrogen chloride (see hydro�  chloric acid) and hydrogen bromide; and in hydrogenation (e.g., of fats).  Liquid hydrogen (boiling point -423 �F [-252.8 �C]) is used in scientific  and commercial applications to produce extremely low temperatures and  as a rocket propellant and a fuel for fuel cells. Combustion of hydrogen  with oxygen gives water as the sole product. The properties of most acids,  especially in water solutions, arise from the hydrogen ion (H + , also  referred to as the hydronium ion, H 3 0 + , the form in which H + is found  in a water environment).

The high temperatures required for the fusion reaction  are produced by detonating an atomic bomb (which draws its energy from  nuclear fission). The bomb�s explosion produces a blast that can destroy  structures within a radius of several miles, an intense white light that can  cause blindness, and heat fierce enough to set off firestorms. It also cre�  ates radioactive fallout that can poison living creatures and contaminate  air, water, and soil. Hydrogen bombs, which may be thousands of times  more powerful than atomic bombs, can be made small enough to fit in the  warhead of a ballistic missile (see ICBM) or even in an artillery shell (see  neutron bomb). Edward Teller and other U.S. scientists developed the first  H-bomb and tested it at Enewetak atoll (Nov. 1, 1952). The Soviet Union  first tested an H-bomb in 1953, followed by Britain (1957), China (1967),  and France (1968). Most modern nuclear weapons employ both fusion and  fission.</p><p>hydrogen bonding Interaction involving a hydrogen atom located  between a pair of other atoms having a high affinity for electrons; such a  bond is weaker than an ionic bond or covalent bond but stronger than van  der Waals forces. Hydrogen bonds can exist between atoms in different  molecules or in parts of the same molecule. One atom of the pair (the  donor), generally a fluorine, nitrogen, or oxygen atom, is covalently  bonded to a hydrogen atom (�FH, �NH, or �OH), whose electrons it  shares unequally; its high electron affinity causes the hydrogen to take on  a slight positive charge. The other atom of the pair, also typically F, N,  or O, has an unshared electron pair, which gives it a slight negative charge.  Mainly through electrostatic attraction, the donor atom effectively shares  its hydrogen with the acceptor atom, forming a bond. Because of its  extensive hydrogen bonding, water (H 2 0) is liquid over a far greater range  of temperatures that would be expected for a molecule of its size. Water  is also a good solvent for ionic compounds and many others because it  readily forms hydrogen bonds with the solute. Hydrogen bonding between  amino acids in a linear protein molecule determines the way it folds up into  its functional configuration. Hydrogen bonds between nitrogenous bases  in nucleotides on the two strands of DNA (guanine pairs with cytosine,  adenine with thymine) give rise to the double-helix structure that is crucial  to the transmission of genetic information.</p><p>reservoir</p><p>A hydro station generates power by the controlled release of water from the reser�  voir of a dammed river. The flowing water turns a turbine, which powers a genera�  tor, creating electricity.

It may involve adding hydrogen at the sites of  double or triple bonds (see bonding) to make them single bonds (i.e., to  saturate an unsaturated compound; see saturation), or to aromatic com�  pounds to make them cyclic hydrocarbons. Edible oils with unsaturated  fatty acids are liquid at room temperature; food manufacturers use hydro�  genation to convert a fraction to saturated fatty acids to make the product  more solid. A second type of hydrogenation involves breaking up a com�  pound (hydrogenolysis, or destructive hydrogenation) and is of great  importance in the petroleum industry. Numerous processes in gasoline and  petrochemical manufacturing are based on it.</p><p>hydrologic \,hl-dr3-'la-jik\ cycle Cycle that involves the continuous  circulation of water in the Earth-atmosphere system. Water is transferred  from the oceans through the atmosphere to the continents and back to the  oceans by means of evaporation, transpiration, precipitation, interception,  infiltration, subterranean percolation, overland flow, runoff, and other  complex processes. Although the total amount of water within the cycle  remains essentially constant, its distribution among the various processes  is continually changing.</p><p>hydrology Scientific discipline concerned with the waters of the Earth,  including their occurrence, distribution, circulation via the hydrologic  cycle, and interactions with living things. It also deals with the chemical  and physical properties of water in all its phases.</p><p>hydrolysis \hl-'dra-ta-s9s\ Chemical reaction in which water (H 2 0 or  HOH) and another reactant exchange functional groups to form two prod�  ucts, one containing the H and the other the OH. In most hydrolyses  involving organic compounds, the other reactants and products are neu�  tral; for example, an ester can be hydrolyzed to form a carboxylic acid and  an alcohol. Such reactions are often accelerated by enzymes (as in much  of digestion and metabolism in general) or other catalysts. In hydrolyses of  compounds with ionic bonds, the nonwater reactants are salts, acids, or  bases, participating in dissociation reactions.</p><p>hydrometallurgy Extraction of metal from ore by dissolving the metal  (as one of its salts) and then recovering it from the solution. The opera�  tions usually involved are leaching (dissolving in water), commonly with  additional agents; separating the waste and purifying the leach solution;  and precipitating the metal or one of its pure compounds from the leach  solution by chemical or electrolytic means. Though hydro metallurgy  originated in the 16th century, its principal development took place in the  20th century. The development of ion exchange, solvent extraction, and  other processes now permits more than 70 metallic elements to be pro�  duced by hydrometallurgy, including most gold, much silver, and large  tonnages of copper and zinc.</p><p>hydroponics Cultivation of plants in nutrient-enriched water, with or  without the mechanical support of an inert medium such as sand or gravel.  Fertilizer solution is pumped through the system periodically. As the  plants grow, concentration of the solution and frequency of pumping are  increased. A wide variety of vegetables and florist crops can be grown  satisfactorily in gravel. Automatic watering and fertilizing saves on labor,  but installation costs are high and fertilizer solution must be tested fre�  quently. Yields are about the same as for soil-grown crops.</p><p>hydrosphere Discontinuous layer of water at or near the Earth�s sur�  face. It includes all liquid and frozen surface waters, groundwater held in  soil and rock, and atmospheric water vapour. Virtually all of these waters  are in constant circulation through the hydrologic cycle. Although the com�  ponents of the hydrosphere are undergoing continuous change of state and  location, the total water budget remains in balance. The components of  the hydrosphere have been seriously affected by the water-polluting activi�  ties of modern society.</p><p>hydrostatics Branch of physics that deals with the characteristics of flu�  ids at rest, particularly with the pressure in a fluid or exerted by a fluid  (gas or liquid) on an immersed body. In applications, the principles of  hydrostatics are used for problems relating to pressure in deep water  (pressure increases with depth) and high in the atmosphere (pressure less�  ens with altitude).</p><p>hydrotherapy External use of water for medical treatment. Wet heat  helps relieve pain, improves circulation, and promotes relaxation. Wet  cold causes blood vessels to close, reducing swelling and pain after injury.  Underwater exercise helps strengthen weak muscles, restore joint motion  after injury, clean and heal burned flesh, aid muscle function after stroke,  and treat arthritic deformity and pain. Whirlpool baths and showers are  also used. Hydrotherapy is usually employed by specialists in physical  MEDICINE AND REHABILITATION.</p><p>hydrothermal ore deposit Any concentration of metallic minerals  formed by the release of solids from hot mineral-laden water (hydrother�  mal solution). The solutions are thought to arise in most cases from the  action of deeply circulating water heated by magma. Another source of  heating that may be involved includes energy released by radioactive  decay.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>918 I hydroxide &#x25BA; hypertext</p><p>hydroxide Any compound with one or more functional groups made  up of one atom each of hydrogen and oxygen, bonded together and acting  as the hydroxide anion (OH - ). Hydroxides include the familiar alkalies of  laboratory and industrial processes. Those of the alkali metals (lithium,  sodium, potassium, rubidium, and cesium), the strongest bases, are the most  stable and soluble; those of the alkaline earth metals (calcium, barium, and  strontium), also soluble strong bases, are less stable. The hydroxides of  most other metals are only slightly soluble but neutralize acids; some are  �amphoteric,� reacting with both acids and bases. In compounds in which  OH is un-ionized and covalently bonded (e.g., in methanol, CH 3 OH), it  is known as a hydroxyl group.</p><p>hyena Any of three species of coarse-furred, doglike carnivores (fam�  ily Hyaenidae) found in Asia and Africa. Actually more closely related to  cats than to dogs, they have four toes on each foot, long forelegs, non-  retractile claws, and enormously strong jaws and teeth. They live alone  or in packs and may be active by night or day. Hyenas are noted for scav�  enging but will also attack live prey. The spotted, or laughing, hyena,  whose calls alternately resemble wailing and maniacal laughter, ranges  through much of sub-Saharan Africa. Yellowish or grayish with dark  spots, it is about 6.5 ft (1.8 m) long, including the 12-in. (30-cm) tail, and  weighs up to 175 lbs (80 kg). It has been known to attack people and even  carry off young children.</p><p>Hyksos \'hik-,s6s\ Group of mixed Semitic-Asiatics who settled in  northern Egypt in the 18th century bc. They seized power c. 1630 bc and  ruled Egypt for 108 years thereafter. They were superficially Egyptian-  ized and did not interfere with Egyptian culture. Their chief deity was  Seth, whom they identified with an Asiatic storm god. The Hyksos intro�  duced the horse and chariot, the compound bow, improved battle-axes,  and advanced fortification techniques. Hyksos pharaohs tried to halt the  spread of a Theban revolt, but their dynasty fell to Ahmose in 1521 bc.</p><p>hylomorphism \ l hl-b- , m6r- l fiz-9m\ Metaphysical view according to  which every natural body consists of two intrinsic principles, one poten�  tial (namely, primary matter) and one actual (namely, substantial form).  It was the central doctrine of Aristotle�s philosophy of nature. He based  his argument for hylomorphism chiefly on the analysis of change. If a  being changes (e.g., from being cold to being hot), something permanent  must exist that remains throughout the change; in addition, there must be  an actual principle that differentiates the earlier from the later state. The  permanent principle is matter, the actual principle form.</p><p>hylozoism \ l hI-b- , zo- l iz-3m\ View that all matter is alive, either in itself  or by participation in the operation of a world soul or some similar prin�  ciple. Hylozoism is logically distinct both from early forms of animism,  which personify nature, and from panpsychism, which attributes some  form of consciousness or sensation to all matter. The word was coined in  the 17th century by Ralph Cudworth, who with Henry More (1614-1687)  spoke of �plastic nature,� an unconscious, incorporeal substance that con�  trols and organizes matter and thus produces natural events as a divine  instrument of change.</p><p>Hymen Greek god of marriage. He was usually thought to be a son of  Apollo by one of the Muses, perhaps Calliope. Other accounts called him  the son of Dionysus and Aphrodite. In Attic legend he was a beautiful youth  who rescued a group of young women, including his beloved, from a gang  of pirates. He obtained the girl in marriage, and their happy life was  invoked in many wedding songs.</p><p>hymn Song used in Christian worship, usually sung by the congrega�  tion and written in stanzas with rhyme and metre. The term comes from  the Greek hymnos (�song of praise�), but songs in honour of God or the  gods exist in all civilizations. Christian hymnody grew out of the singing  of psalms in the Temple of Jerusalem. The earliest known Christian hymn  dates from c. ad 200. Hymns were prominent in the Byzantine liturgy  from early times, and in the Western church they were sung by congre�  gations until the Middle Ages, when choirs took over hymn singing. Con�  gregational singing was reestablished during the Reformation. Martin  Luther and his followers were great hymn writers, while the Calvinists  preferred setting psalms to music. The compositions of Isaac Watts and  John Wesley were notable in English hymnody. The Counter-Reformation  led to the composition of many Roman Catholic hymns, and the Roman  Catholic church restored congregational singing of hymns after the Sec�  ond Vatican Council in the 1960s.</p><p>Hyndman Vhlnd-msnV Henry M(ayers) (b. March 7, 1842, Lon�  don, Eng.�d. Nov. 22, 1921, London) British Marxist political leader.  Educated at the University of Cambridge, he worked as a journalist before  founding the socialist Democratic Federation, and in England for All  (1881), the first English socialist book in almost 50 years, he expounded  the ideas of Karl Marx. He steered many British socialists toward Marx�  ism, but Friedrich Engels, who disliked Hyndman, encouraged many to  break away and form the Socialist League. During World War I Hyndman  took a patriotic and pro-French line, causing his ouster from the Socialist  Party, whereupon he formed the National Socialist Party (1916), later  renamed the Social Democratic Federation.</p><p>hyperactivity See attention deficit disorder</p><p>hyperbaric chamber \,hl-p9r-'bar-ik\ 0 / decompression cham�  ber or recompression chamber Sealed chamber supplying a high-  pressure atmosphere. Breathing air at high pressure increases the oxygen  level in tissues. This is used to inhibit growth of anaerobic bacteria (as in  tetanus or gas gangrene); to increase the chance that babies with certain  heart malformations will survive heart surgery; or to cause air bubbles (as  in air embolism or decompression sickness) to be redissolved, carried to the  lungs, and exhaled as pressure is gradually returned to normal.</p><p>hyperbola \hl-'p9r-b3-la\ Curve with two separate branches, one of the  conic sections. In Euclidean geometry, the intersection of a double right cir�  cular cone and a plane at an angle that is less than the cone�s generating  angle (the angle its sides make with its central axis) forms the hyperbo�  la�s two branches (one on each nappe, or single cone). In analytic geom�  etry, the standard equation of a hyperbola is x 2 /^ 2 - y 2 / b 2 = 1. Hyperbolas  have many important physical attributes that make them useful in the  design of LENSes and antennas.</p><p>hyperbolic \,hl-p3r-'ba-lik\ function In mathematics, one of a set of  functions related to the hyperbola in the same way the trigonometric func�  tions relate to the circle. They are the hyperbolic sine, cosine, tangent,  secant, cotangent, and cosecant (written �sinh,� �cosh,� etc.). The hyper�  bolic equivalent of the fundamental trigonometric identity is cosh 2 z -  sinh 2 z = 1. The hyperbolic sine and cosine, particularly useful for finding  special types of integrals, can be defined in terms of exponential functions:  sinhx = (e<emphasis> � e ~ x ) 4- 2 and coshx = (e</emphasis> + e ~ x ) -4 2</p><p>hyperbolic geometry Non-Euclidean geometry, useful in modeling  interstellar space, that rejects the parallel postulate, proposing instead that  at least two lines through any point not on a given line are parallel to that  line.

Over time, it damages the kidneys, brain, eyes,  and heart. Hypertension accelerates atherosclerosis, increasing the risk of  heart attack, stroke, and kidney failure. More common in the elderly and  blacks, it usually has no symptoms but can be detected by a routine blood-  pressure test. Secondary hypertension, caused by another disorder (most  often kidney disease or hormone imbalance), accounts for 10% of cases.  The other 90% have no specific cause (essential hypertension). A low-salt  diet, weight loss, smoking cessation, limited alcohol intake, and exercise  can prevent or treat hypertension or reduce medication if drug therapy  proves necessary. Malignant hypertension, a severe, rapidly progressing  form, requires emergency treatment with drugs to dilate the blood vessels.</p><p>hypertext or hyperlink Linking of related information by electronic  connections in order to allow a user easy access between them. Concep�  tualized by Vannevar Bush (1945) and invented by Douglas Engelbart in  the 1960s, hypertext is a feature of some computer programs that allows  the user to select a word and receive additional information, such as a  definition or related material. In Internet browsers, hypertext links (hot-  links) are usually denoted by highlighting a word or phrase with a dif�  ferent font or colour. Hypertext links create a branching or network  structure that permits direct, unmediated jumps to related information.  Hypertext has been used most successfully as an essential feature of the  World Wide Web (see HTML; HTTP).

The hyp�  notized individual seems to respond in an uncritical, automatic fashion,  ignoring aspects of the environment (e.g., sights, sounds) not pointed out  by the hypnotist. Even the subject�s memory and awareness of self may  be altered by suggestion, and the effects of the suggestions may be  extended (posthypnotically) into the subject�s subsequent waking activ�  ity. The history of hypnotism is as old as that of sorcery and magic. It was  popularized in the 18th century by Franz Anton Mesmer (as �mesmerism�)  and was studied in the 19th century by the Scottish surgeon James Braid  (1795-1860). Sigmund Freud relied on it in exploring the unconscious, and  it eventually came to be recognized in medicine and psychology as useful  in helping to calm or anesthetize patients, modify unwanted behaviours,  and uncover repressed memories. There remains no generally acceptable  explanation for hypnosis, though one prominent theory focuses on the  possibility of discrete dissociative states affecting portions of conscious�  ness.</p><p>hypochondriasis N.hl-ps-kon-'dri-o-sosV Mental disorder in which an  individual is excessively preoccupied with his own health and inclined to  treat insignificant physical signs or symptoms as evidence of a serious  disease. The hypochondriac may become convinced that he is ill even  though he has no symptoms at all, or may exaggerate the importance of  minor aches and pains, becoming obsessed with the fear of a life-  threatening illness. A doctor�s reassurances often have only a slight or  temporary effect on the hypochondriac�s anxieties. Hypochondriasis usu�  ally first manifests itself in early adulthood and is equally common among  males and females. In some cases it may represent a psychological cop�  ing mechanism that the individual resorts to in order to deal with stress�  ful life situations.</p><p>hypoglycemia X.hl-pd-gll-'se-me-oX Below-normal levels of blood  glucose, quickly reversed by administration of oral or intravenous glu�  cose. Even brief episodes can produce severe brain dysfunction. Fasting  hypoglycemia can be life-threatening; it occurs most often in patients with  diabetes mellitus who mistime insulin therapy or miss meals. It also results  from insulin-producing tumours, starvation, or metabolic disorders. Reac�  tive hypoglycemia occurs when the body produces too much insulin in  response to sugar intake. Symptoms range from irritability to confusion  and seizures, leading to coma and death in severe cases.</p><p>hypophosphatemia V.hl-po-.fas-fa-'te-me-oX Low phosphate levels in  blood. It usually occurs in conjunction with other metabolic disturbances,  disrupting energy metabolism and impairing delivery of oxygen to tis�  sues. Acute hypophosphatemia causes neurological symptoms (weakness,  tremors, and confusion). Chronic hypophosphatemia, from long-term  deficiency, causes general weakness and appetite loss. Treatment involves  correcting the metabolic problem and giving phosphate supplements.  Familial hypophosphatemia, an inherited disorder, is a major cause of  rickets in developed nations.

The design allows for the construc�  tion of large spaces without arches. It was used extensively in ancient  Egypt (e.g.. Temple of Amon at Karnak) and Persia. The elaborately  carved pillars consumed much of the floor space and therefore assumed  great importance. Hypostyles are rarely seen in more recent architecture  because of more effective means of roof support.</p><p>hypotension or low blood pressure Condition in which blood  pressure is abnormally low. It may result from reduced blood volume (e.g.,  from heavy bleeding or plasma loss after severe burns) or increased blood�  vessel capacity (e.g., in syncope). Orthostatic hypotension�drop in blood  pressure on standing�results from failure of the reflexes that contract  muscles and constrict blood vessels in the legs to offset gravity as one  rises. Hypotension is also a factor in poliomyelitis, shock, and barbiturate  poisoning.</p><p>hypothalamus V.hl-po-'tha-lo-mosX Region of the brain containing a  control centre for many autonomic-nervous-system functions. Its complex  interaction with the pituitary gland makes it an important part of the endo�  crine system. As a critical link between the body�s two control systems, the</p><p>hypothalamus regulates homeostasis. Nervous and hormonal pathways  connect it with the pituitary, which it stimulates to release various hor�  mones. The hypothalamus influences food intake, weight regulation, fluid  intake and balance, thirst, body heat, and the sleep cycle. Disorders can  produce pituitary dysfunction, diabetes insipidus, insomnia, and temperature  fluctuations.</p><p>hypothermia Abnormally low body temperature, with slowing of  physiological activity. It is artificially induced (usually with ice baths) for  certain surgical procedures and cancer treatments. Accidental hypother�  mia can result from falling into cold water or overexposure in cold  weather. Underlying conditions such as cerebrovascular disease or intoxi�  cation increase the risk from exposure. Hypothermia is serious when body  temperature is below 95 �F (35 �C) and an emergency below 90 �F (32.2  �C), at which point shivering stops. Pulse, respiration, and blood pressure  are depressed. Even when the victim appears dead, revival may be pos�  sible with very gradual passive rewarming (e.g., with blankets). See also  FROSTBITE.</p><p>hypothesis testing In statistics, a method for testing how accurately  a mathematical model based on one set of data predicts the nature of other  data sets generated by the same process. Hypothesis testing grew out of  quality control, in which whole batches of manufactured items are  accepted or rejected based on testing relatively small samples. An initial  hypothesis (null hypothesis) might predict, for example, that the widths  of a precision part manufactured in batches will conform to a normal dis�  tribution with a given mean (see mean, median, and mode).

First settled by the Egba, the modern city probably grew from  a camp set up by Yoruba armies from Ife, Ijebu, and Oyo; it was taken  by the British in 1893. An important commercial centre, it contains six  parks, the most important of which is Agodi Garden. It is the seat of the  University of Ibadan (1948) as well as a polytechnic and other special�  ized institutions. Two major stadiums and television studios are also  located there.</p><p>Ibague \,e-ba-'ga\ City (pop., 1999 est.: 393,664), central Colombia. It  is located on the eastern slopes of the Cordillera Central of the Andes  Mountains. Founded in 1550 on the site of an Indian village, it was moved  to its present location for protection from Indian attacks. It was the  nation�s capital briefly in 1854. Its location on a road linking the cities  of Armenia and Bogota has made it a busy commercial centre. It is the  seat of Tolima University.</p><p>Ibanez \e-'ban-yas\ (del Campo), Carlos (b. Nov. 3, 1877, Chilian,  Chile�d. April 28, 1960, Santiago) Chilean soldier and president (1927-  31, 1952-58). After a 30-year military career, he helped overthrow Pres.  Arturo Alessandri Palma in 1924 and effectively controlled Chile until  1931. Backed by the army, he exiled or jailed all opponents, but he failed  in his attempt to rescue the ailing nitrate industry despite the help of U.S.  capital. As the economy crumbled, discontent with Ibanez�s authoritari�  anism became overt, and he fled the country. After twice attempting to  regain power with the help of Chilean fascists, he won the 1952 presi�  dential election by appealing to depressed workers and proved to be a  more democratic leader than expected.

In 1918 she published an article using her pseudonym (�The  Passionflower�), and in 1920 she joined the new Communist Party of  Spain. After a turbulent career, she emerged as a deputy in the Republi�  can parliament. By the outbreak of the Spanish Civil War in 1936 she had  won fame as a fiery and even violent street orator, and she coined the  Republican battle cry, �No pasaran!� (�They shall not pass!�). With Fran�  cisco Franco�s victory in 1939 she fled to the Soviet Union; she returned  in 1977 after his death and the party�s relegalization. Reelected to parlia�  ment, she resigned because of ill health, but she remained  honourary president of the party until her death.</p><p>Iberian Any member of a prehistoric people of southern and east�  ern Spain. They were largely untouched by the migrations of Celtic  peoples to northern and central Spain beginning in the 8th century  bc. Culturally they were influenced by Greek and Phoenician trad�  ing colonies. On the eastern coast, tribes seem to have formed inde�  pendent city-states; in the south, they formed monarchies. Their  economy was based on agriculture, mining, and metallurgy. Their  non-Indo-European language continued into Roman times.</p><p>Iberian Peninsula or Iberia Peninsula, southwestern Europe,  occupied by Spain and Portugal. Its name derives from its ancient  inhabitants whom the Greeks called Iberians, probably after the Ebro  (Iberus) River, the peninsula�s second longest river. The Pyrenees form  a land barrier in the northeast from the rest of Europe, and in  the south at Gibraltar the peninsula is separated from North  Africa by a narrow strait. Its western and northern coasts are  bordered by the Atlantic Ocean, and its eastern coast by the  Mediterranean Sea.

Referred to as Shaytan (Satan) in this context, it was he who purportedly  tempted Adam and Eve in the Garden of Eden and caused the Fall. Iblls  has long been a figure of speculation among Muslim scholars because of  his ambiguous identification in the Qur�an as either an angel or a jinni.</p><p>IBM Corp. in full International Business Machines Corpora�  tion Leading U.S. computer manufacturer, headquartered in Armonk,  N.Y. It was incorporated in 1911 as the Computing-Tabulating-Recording  Co., a consolidation of three office-products companies. It adopted its  present name in 1924 under the leadership of Thomas J. Watson, Sr., who  built it into the major U.S. manufacturer of punch card tabulators. IBM  bought an electric typewriter company in 1933 and soon secured a large  share of that market. In the early 1950s it entered the computer industry,  investing heavily in development, and in the 1960s it produced 70% of the  world�s computers. Its initial specialty was mainframe computers, but in  1981 it produced its first personal computer, the IBM PC. IBM quickly  became a leader in this field, but fierce competition undermined its market  share and forced the company to retrench in the 1990s.

After retiring from politics in 1375, he  wrote his masterpiece, the Muqaddimah (�Introduction�), in which he  examined the nature of society and social change and developed one of  the earliest rational philosophies of history. He also wrote a definitive his�  tory of Muslim North Africa, Kitab al-lbar. In 1382 he went to Cairo,  where he was appointed professor of law and religious judge. In 1400 he  was trapped in Damascus during that city�s siege by Timur, spending seven  weeks in the Central Asian conqueror�s camp before securing his own  release and that of a number of colleagues.

His administration was relatively enlightened; he created a  consultative council and suppressed the feudal regime. Sultan Mahmud II  (r. 1808-39) then sent an Ottoman army to invade Syria, and Ibrahim won  his greatest victory in 1839 when the Ottoman fleet deserted to Egypt.

Below 32 �F (0 �C),  liquid water forms a hard solid and water vapour forms frost on surfaces  and snowflakes (see snow) in clouds. Unlike most liquids, water expands  on freezing, so ice is less dense than liquid water and therefore floats. It  consists of compact aggregates of many crystals (with hexagonal sym�  metry), although ice formed from the bulk liquid does not normally have  crystal faces. Molecules in the crystal are held together by hydrogen bonds  (see hydrogen bonding). With a very high dielectric constant, ice conducts  electricity much better than most nonmetallic crystals.

Icebergs are typically found in open seas,  especially around Greenland and Antarctica. They form mostly during  each hemisphere�s spring and summer, when warmer weather increases  the rate of calving (separation) of icebergs at the boundaries of the Green�  land and Antarctic ice sheets and smaller outlying glaciers. In the North�  ern Hemisphere, about 10,000 icebergs are produced each year from the  Greenland glaciers, and an average of 375 flow into the North Atlantic  shipping lanes, where they are a hazard to navigation, especially because  only about 10% of an iceberg is exposed above the surface of the sea.</p><p>Iceland officially Republic of Iceland Island country, northern  Atlantic Ocean, between Norway and Greenland.

Reli�  gion: Christianity (Evangelical Lutheran [official]). Currency: krona. One  of the most active volcanic regions in the world, Iceland contains about  200 volcanoes and accounts for one-third of Earth�s total lava flow. One-  tenth of the area is covered by cooled lava beds and glaciers, including  Vatnajokull. Iceland�s rugged coastline is more than 3,000 mi (4,800 km)  long. The economy is based heavily on fishing and fish products but also  includes hydropower production, livestock, and aluminum processing.  Iceland is a republic with one legislative house; its chief of state is the  president, and the head of government is the prime minister. Iceland was  settled by Norwegian seafarers in the 9th century and was Christianized  by 1000. Its legislature, the Althingi, founded in 930, is one of the oldest  legislative assemblies in the world. Iceland united with Norway in 1262  and with Denmark in 1380. It became an independent state of Denmark  in 1918, but it severed those ties to become an independent republic in  1944. Vigdis Finnbogadottir, the first woman in the world to be elected a  head of state, served four terms as the republic�s president (1980-96).

His  other equipment included a copper ax, a flint dagger, a yew bow, and a  deerskin quiver holding expertly finished arrows. Although it was initially  believed that he had died of freezing, X-ray examination in 2001 showed  that an arrowhead was lodged in his left shoulder, suggesting that he had  likely bled to death after being shot.</p><p>Ichikawa \,e-che-'ka-wa\ Kon (b. Nov. 20, 1915, Ise, Japan) Japanese  film director. After working in the animation department of the Toho film  studio, he directed his first film, The Girl at Dojo Temple (1946). He  introduced sophisticated Western-style comedy to Japan in films such as  The Woman Who Touched Legs (1952) and Mr. Pu (1953). He gained  international acclaim for his antiwar films The Burmese Harp (1956) and  Fires on the Plain (1959) and the documentary Tokyo Olympiad (1965).  His other major films include Conflagration (1958), My Enemy the Sea  (1963), and An Actor�s Revenge (1963).</p><p>ICI See Imperial Chemical Industries PLC</p><p>icon In Eastern Orthodoxy, the representation of sacred persons or events  in murals, mosaics, or paintings on  wood. After the Iconoclastic Contro�  versy of the 8th-9th century, which  disputed the religious function and  meaning of icons (see iconoclasm),  the Eastern churches formulated an  official doctrine that approved their  use, stating that since God had  assumed material form in the person  of Jesus, he and other sacred person�  ages could be represented in works  of art. Usually depicting Jesus or  Mary but also sometimes saints,  icons are relied on as objects of ven�  eration and as tools for instruction.</p><p>iconoclasm Destruction of reli�  gious images. In Christianity and  Islam, iconoclasm was based on the  Mosaic prohibition against making  graven images, which were associ�  ated with idolatry. The making of  portraits of Christ and the saints was  opposed in the early Christian  church, but icons had become popu�  lar in Christian worship by the end of the 6th century, and defenders of  icon worship emphasized the symbolic nature of the images. Opposition  to icons by the Byzantine emperor Leo III in 726 led to the Iconoclastic  Controversy, which continued in the Eastern church for more than a cen�  tury before icons were again accepted. Statues and portraits of saints and  religious figures were also common in the Western church, though some  Protestant sects eventually rejected them. Islam still bans all icons, and  iconoclasm has played a role in the conflicts between Muslims and Hin�  dus in India.</p><p>iconostasis Vj-ko-'nas-to-sosV In Eastern Christian churches of Byzan�  tine tradition, a solid screen of stone, wood, or metal separating the sanc�  tuary from the nave. It has a royal door in the center and two smaller  doors on either side. Covered with panel icons, it always includes the icon  of the Incarnation (mother with child) on the left and the second coming  of Christ on the right; icons of the four Evangelists, the Annunciation,  and the Last Supper cover the royal doors themselves.</p><p>id In Freudian psychoanalytic theory, one of the three aspects of the  human personality, along with the ego and superego. The id is the source  of instinctual impulses such as sex and aggression as well as primitive  needs that exist at birth. It is entirely nonrational and functions accord�  ing to the pleasure-pain principle, seeking immediate fulfillment of its  impulses whenever possible. Its working processes are completely uncon�</p><p>scious in the adult, but it supplies the energy for conscious mental life,  and it plays an especially important role in modes of expression that have  a nonrational element, such as the making of art. The primary methods  for unmasking its content, according to Sigmund Freud, are dream analy�  sis and free association.</p><p>Ida, Mount Name of two separate mountains, one in Anatolia and the  other on the island of Crete. The Anatolian mountain is located near the  site of ancient Troy and once held a Classical shrine where Paris is said  to have judged the beauty of three Greek goddesses. From its highest  point, about 5,800 ft (1,800 m), the gods are said to have witnessed the  Trojan War. The second mountain, in west-central Crete, is the island�s  highest point, reaching 8,058 ft (2,456 m). It also held a Classical shrine,  which included the cave where Zeus, the father of the Greek pantheon,  was said to have been reared.</p><p>Idaho State (pop., 2000: 1,293,953), northwestern U.S. It is bordered by  Canada and the U.S. states of Montana, Wyoming, Utah, Nevada, Oregon,  and Washington. It covers 83,574 sq mi (216,456 sq km). Its capital is  Boise. Idaho is dominated by the Rocky Mountains, which extend from the  Canadian border to south-central Idaho and along the Wyoming border.  Its most extensive valley surrounds the Snake River, which flows through  Hells Canyon, the deepest gorge in North America. First occupied by  American Indians, the region was explored by the Lewis and Clark Expe�  dition in 1805. It was part of the disputed Oregon Country that passed to  the U.S. when Britain relinquished its claims by treaty in 1846. Discov�  ery of gold in 1860 brought an influx of settlers. It became Idaho Terri�  tory in 1863 and was admitted to the Union as the 43rd state in 1890.  Labour protests during 1890-1910 involving the Industrial Workers of the  World erupted frequently. During the late 20th century, Idaho developed  its agriculture and industry and promoted its natural wilderness.</p><p>ideal gas See perfect gas</p><p>idealism In metaphysics, the view that stresses the central role of the ideal  or the spiritual in the constitution of the world and in mankind�s interpre�  tation of experience. Idealism may hold that the world or reality exists  essentially as spirit or consciousness, that abstractions and laws are more  fundamental in reality than sensory things, or, at least, that whatever exists  is known to mankind in dimensions that are chiefly mental�that is,  through and as ideas. Metaphysical idealism asserts the ideality of reality;  epistemological idealism holds that in the knowledge process the mind  can grasp only its own contents. Metaphysical idealism is thus directly  opposed to materialism, and epistemological idealism is opposed to realism.  Absolute idealism (see G. W. F. Hegel) includes the following principles:  (1) the everyday world of things and persons is not the world as it really  is but merely as it appears in terms of uncriticized categories; (2) the best  reflection of the world is in terms of a self-conscious mind; (3) thought is  the relation of each particular experience with the infinite whole of which  it is an expression; and (4) truth consists in relationships of coherence  between thoughts, rather than in a correspondence between thoughts and  external realities (see coherentism).

After studies in Germany he served as a synagogue cantor  there (from 1903) before moving to Johannesburg and then to Jerusalem  in 1905. Later he moved to the U.S., but after a stroke in 1934 he returned  to Johannesburg. His monumental comparative studies of Jewish music  in many parts of the world established that the tradition had remained  relatively unchanged over time and also suggested connections between  Jewish chant and the origins of Gregorian chant. He composed the first  Hebrew opera, Yiftah (1922), and the song �Hava nagila.�</p><p>Identity Christianity North American Christian movement that iden�  tifies Anglo-Saxon and other European peoples with the lost tribes of  Israel. Anti-Semitic and racist, Identity Christianity posits that God�s cov�  enant was actually with the European peoples and that the Jews are the  offspring of Eve and Satan, and it characterizes blacks as subhuman.  Though it has been largely unsuccessful in persuading �white Israelites�  of their purported identity, small churches are active (mainly in the north�  western U.S.) and the movement proselytizes through publications,  recordings, and the Internet.</p><p>identity of indiscernibles Principle enunciated by G.W.

More  formally, the principle states that if x is not identical to y, then there is  some non-relational property P such that P holds of x and does not hold  of y, or that P holds of y and does not hold of x. Equivalently, if x and y  share all their non-relational properties, then x is identical to y. Its con�  verse, the principle of the indiscemibility of identicals (also known as  Leibniz�s Law), asserts that if x is identical to y, then every non-relational  property of x is a property of y, and vice versa.</p><p>identity theory In the philosophy of mind, the doctrine that mental  events are identical to physico-chemical events in the brain. So-called  �type� identity theory asserts that each type of mental event, such as pain,  is identical to some type of event in the brain, such as the firing of c-fibres.  In response to objections based on the assumed �multiple realizability�  of mental states, �token� identity theory makes the weaker claim that each  token of a mental event, such as a particular pain, is identical to some  token of a brain event of some type. See also mind-body problem.</p><p>ideology Form of social or political philosophy in which practical ele�  ments are as prominent as theoretical ones. The term was coined in 1796  by the French writer Antoine-Louis-Claude, Comte Destutt de Tracy (b.  1754�d. 1836), as a label for his �science of ideas.� Certain character�  istics of his thought proved generally true of ideologies, including a more  or less comprehensive theory of society, a political program, anticipation  of a struggle to implement that program (thus requiring committed fol�  lowers), and intellectual leadership. Destutt de Tracy�s ideas were adopted  by the French Revolutionary government in building its version of a  democratic, rational, and scientific society (see Directory). Napoleon first  gave the term a negative connotation with his scorn for what he called  ideologues. Ideology is often contrasted unfavourably with pragmatism.  The significance of ideology follows from the fact that power is rarely  exercised without some ideas or beliefs that justify support.</p><p>Iditarod \,I- , dit-3- l rad\ Trail Sled Dog Race U.S. dogsled race. It is  held each March and run over a route between Anchorage and Nome,  Alaska. It originated in 1967 as a race 56 mi (90 km) long, but by 1973  it had evolved into the current race, a 1,152-mi (1,855-km) trek roughly  tracing an old mail route established in 1910. The race also commemo�  rates an emergency mission to get medical supplies to Nome during a  diphtheria epidemic in 1925. It typically takes 9-14 days to complete the  race. See also dogsled racing.</p><p>idol Image or statue of a deity used as an object of worship. In Judaism, the  making of any representation of God is strictly forbidden, as is the fash�  ioning of any �graven image.� Islam has also adhered to this rule. In Chris�  tianity, there has been a general acceptance of pictorial or sculpted images  of Jesus and the saints and, on occasion, God, and Christianity has thus  always faced the danger that such representations could be venerated  superstitiously as idols. In Jainism, Hinduism, and Buddhism images of  gods and saints are common; they are often the object of veneration. In Hin�  duism, a statue may be treated as a god as an act of devotion but loses its  special status when the act of devotion is finished (see Durga-puja, puja).</p><p>Idris \id-'res\ I in full SIdl Muhammad Idris al-Mahdl  al-SanusT (b.

He succeeded his father  in 1902 as leader of Cyrenaica but did not rule in his own name until 1916.  Negotiations with Italy, which held the Libyan coast, resulted in agree�  ments that confirmed Idris�s authority (1917) and established a parliament  (1919). His refusal to disarm his tribal supporters, however, led to Italy�s  invasion of Tripolitania in 1922, and Idris went into exile until after World  War II (1939�45). In 1949 Cyrenaica and the other two Libyan provinces  united under a constitutional monarchy headed by Idris. Independence  was declared in 1951. He was overthrown by Col. Muammar al-Qaddafi  in a military coup in 1969.</p><p>Idrlsid \'id-ri-sid\ dynasty Arab Muslim dynasty that ruled Berber  areas of Morocco (789-921). The founder, Idris I (r. 789-791), established  the shariflan tradition in Morocco, by which the claim to descent from  Muhammad was established as the principle for monarchic rule. His son  Idris II (r. 803-828) founded Fez (modern Fes) in 808. The dynasty was  the first to incorporate both Berbers and Arabs. It broke up into rival prin�  cipalities, paving the way for another Berber group, the Almoravid dynasty.</p><p>idyll or idyl Vl-dal, 'i-dal\ In literature, a simple descriptive work in  poetry or prose that deals with rustic life or pastoral scenes or suggests a  mood of peace and contentment.

Flourishing in the  fertile uplands, it was established through the conquests of a 13th-century  ruler known as Walashma. It served as a buffer between the kingdom of  Damot and the Christian kingdom of Ethiopia. Ifat was conquered by the  Ethiopian king Amda Tseyon in 1328 and made tributary to Ethiopia. After  a long series of revolts, it was destroyed in 1415 when it was annexed to  Ethiopia.</p><p>Ifni \'if-ne\ Region, southwestern Morocco. Located on the coast of the  Atlantic Ocean, it has an area of some 580 sq mi (1500 sq km). It was  settled in 1476 by Diego Garcia de Herrera, lord of the Canaries, as a  Spanish fishing, slaving, and trading locality. Abandoned in 1524 because  of disease and the hostility of the local population, Spain reclaimed it fol�  lowing a treaty with Morocco in 1860. Effective Spanish reoccupation  began in 1934, and it became part of Spanish West Africa in 1946. Ifni  was ceded to Morocco in 1969.</p><p>IG Farben World�s largest chemical cartel from its founding in Germany  until its dissolution by the Allies after World War II. It grew out of a com�  plex merger of German manufacturers of chemicals, pharmaceuticals, and  dyestuffs {Farben). Its major members were the companies known today as  BASF AG, Bayer AG, Hoechst AG, Agfa-Gevaert Group, and Cassella AG.  They formed a loose association in 1916 and were formally united in 1925,  with headquarters in Frankfurt. IG Farben expanded internationally in the  late 1920s and the 1930s. During World War II, it established a synthetic oil  and rubber plant at Auschwitz to take advantage of slave labour by the death  camp�s inmates, on whom it also conducted drug experiments. After the  war, several company officials were convicted of war crimes, and IG Farben  was broken up into three independent companies.</p><p>Igbo \'ig-bo\ or Ibo Ve-bo\ People of southeastern Nigeria. The Igbo  speak dialects of Igbo, a Benue-Congo language of the Niger-Congo fam�  ily (see Niger-Congo languages). Before European colonization the Igbo  lived in autonomous local communities, but by the mid 20th century they  had developed a strong sense of ethnic identity. During conflicts in 1966  many Igbo in northern Nigeria were killed or forced into their traditional  homelands in the east. In 1967 the Eastern region tried to secede from  Nigeria as the independent nation of Biafra; hundreds of thousands of Igbo  were killed or died of starvation. Today they number some 20 million.  Many are farmers, but trading, crafts, and wage labour are also important,  and many have become civil servants and business entrepreneurs.</p><p>igloo Temporary dome-shaped winter home or hunting-ground dwelling  of Canadian and Greenland Inuit (Eskimos), made from blocks of snow.  The builder chooses a deep snowdrift of fine-grained, compact snow and  cuts it into blocks.

Additional blocks are added to the spiral to draw it inward until a  dome is completed, leaving a ventilation hole at the top.</p><p>Ignarro, Louis J(oseph) (b. May 31,1941, Brooklyn, N.Y., U.S.) U.S.  pharmacologist. He earned a Ph.D. from the University of Minnesota.  Along with Robert F. Furchgott and Ferid Murad, Ignarro was awarded a  1998 Nobel Prize for the discovery that nitric oxide acts as a signaling mol�  ecule in the cardiovascular system. Ignarro concluded that the factor that  Furchgott had named endothelium-derived relaxing factor was nitric oxide.  This work uncovered an entirely new mechanism by which blood vessels  in the body relax and widen. It was the first discovery that a gas could act  as a signaling molecule in a living organism. The principle behind the drug  Viagra, used to treat impotence, was based upon this research.</p><p>Ignatius of Antioch \ig-'na-sh3s\, Saint (d. c. 110, Rome; Western  feast day October 17; Eastern feast day December 20) Early Christian  martyr. Probably of Syrian origin, he may have been a pagan who per�  secuted Christians before his conversion. He succeeded St. Peter the  Apostle as bishop of Antioch. During the reign of Trajan, Roman authori�  ties arrested Ignatius and sent him to Rome, where he was tried and  executed. He wrote a series of famous letters on the journey to Rome,  attempting to encourage his fellow Christians during their persecution.  The letters condemn two sets of heretics: the Judaizers, who insisted that  Christians continue to follow Jewish law, and the Docetists, who main�  tained that Jesus only appeared to suffer and die on the cross.</p><p>Ignatyev \ig-'nat-yiA, Nikolay (Pavlovich), Count (b.

Appointed head of the foreign ministry�s Asian depart�  ment, he gained jurisdiction over Russia�s relations with the Ottoman  Empire as well, and in 1864 he became ambassador to Constantinople.  An advocate of Pan-Slavism, he encouraged Serbia and Bulgaria in a revolt  that proved unsuccessful. In 1878, after Russia�s victory in the Russo-  Turkish War, he negotiated the favourable Treaty of San Stefano. The  western European powers replaced it with the Treaty of Berlin, far less  favourable to Russia, and he was forced to resign.</p><p>igneous rock Any of various crystalline or glassy, noncrystalline rocks  formed by the cooling and solidification of molten earth material (magma).  Igneous rocks comprise one of the three principal classes of rocks, the  others being metamorphic and sedimentary rocks. Though they vary widely  in composition, most igneous rocks consist of quartz, feldspars,  pyroxenes, amphiboles, micas, olivines, nepheline, leucite, and apatite.  They may be classified as intrusive or extrusive rocks.</p><p>ignition system In a gasoline engine, the means used for producing an  electric spark to ignite the fuel-air mixture in the cylinders to produce the  motive force. The ignition system consists of a storage battery recharged  by a generator, an induction coil, a device to produce timed high-voltage  discharges from the induction coil, a distributor, and a set of spark plugs.  The battery provides an electric current of low voltage, usually 12 volts,  that is converted by the system to some 40,000 volts. The distributor  routes the successive bursts of high-voltage current to each spark plug in  the proper firing order.</p><p>iguana \i-'gwa-n3\ Any of about 13 of the larger members of the lizard  family Iguanidae. Best known is the common iguana {Iguana iguana ),  which ranges from Mexico southward to Brazil. It reaches a maximum  length of 6 ft (1.8 m). It lives in trees, especially trees overhanging water,  into which it will plunge if disturbed. It is greenish, with brown bands  that form regular rings on the tail. It primarily eats tender leaves and fruits  but will also eat small birds and crustaceans. Species of the southwestern  U.S. and Mexico include the chuckwalla {Sauromalus obesus) and desert  iguana {Dipsosaurus dorsalis).</p><p>Iguazu Falls or Iguacu \,e-gw3-'su\ FaWs, formerly Victoria Falls</p><p>A series of cataracts on the Iguazu River near the border between Argen�  tina and Brazil.

In response to Commodore Matthew Perry�s  demand that Japan end its centuries-old policy of isolation, Ii favoured  developing relations. The Tokugawa shogun signed the Perry Convention  (1854), which opened two ports to U.S. ships, exposing the country to  Western influence, and began negotiations with Townsend Harris over  trade. In an unusual move, the shogunate had sought the emperor�s con�  sent to the treaty; when antitreaty forces blocked approval, Ii, as head of  the shogunal governing body, authorized the signing. This outraged many  daimyo; when Ii silenced them, he was beheaded by assassins. See also  Tokugawa period; Meiji Restoration.</p><p>lio Sogi Vso-ge\ or Sogi (b. 1421, Japan�d.

It was intro�  duced in Japan in the 6th century by Chinese Buddhist missionaries, who  had formalized the ritual of offering flowers to the Buddha. The first school  of flower arranging in Japan was founded in the early 7th century. The  art is based on harmony of simple linear construction and appreciation of  the subtle beauty of flowers and natural material (branches, stems). Sev�  eral major schools, with differing histories and theories of artistic style,  exist to this day. In its highest form, ikebana is spiritual and philosophi�  cal in nature, but in modern Japan it is more often practiced as a sign of  refinement by marriageable young women or older matrons.</p><p>Ikhwan \ik-'wan\ Arabic "Brethren" Religious and military broth�  erhood that helped I BN Sa'ud unite the Arabian Peninsula. First organized  in 1912, its members were settled in colonies around oases in an effort to  break down tribal loyalties and force the Bedouin to abandon their nomadic  way of life. They also embraced the arch-traditionalist Islamic principles  of Muhammad ibn �Abd al-WAHHAB. From 1919 they won many victories  in Arabia and Iraq, with conquests including Mecca and Medina. By 1926  the Ikhwan were becoming uncontrollable, attacking Ibn Sa'ud for inno�  vations such as telephones and automobiles. They staged a bloody revolt,  which was not put down until 1930, and then only with British help.

Though the welfare of the city dweller improved during Tokugawa (Edo)  times, the welfare of poor peasants worsened: excessive taxation and ris�  ing numbers of famines drove them first to peaceful and then to violent  demonstrations. They sometimes received redress for particular hardships,  but their spokesmen would forfeit their lives for their audacity.</p><p>II Rosso See Giovanni Battista Rosso  ilang-ilang See ylang-ylang</p><p>ileitis \,i-le-'i-t3s\ Chronic inflammation of part of the small intestine or  large intestine (strictly, of the ileum). A more serious type, regional ileitis  (Crohn disease), involves both small and large intestines. Ileitis symp�  toms include chronic or intermittent, sometimes bloody, diarrhea and  abdominal cramps. Fever, weight loss, and anemia may occur. Crohn dis�  ease may involve progressive deterioration. Obstructions or abnormal  connections between loops of intestine may develop. Simple ileitis has  short-term causes, and many patients recover completely. In Crohn dis�  ease, which may result from an autoimmune defect, remissions and  relapses continue for years, causing the intestine�s wall to thicken, its  channel to narrow, and its lining to ulcerate. X-ray films or colonoscopy  showing these features are diagnostic. Drug treatment may help, but there  is no known cure, and the disease often requires removal of part of the  intestine.</p></section><section><p>ileum Vi-le-amV Final and longest segment of the small intestine. It is the  site of absorption of vitamin B 12 (see vitamin B complex) and reabsorption  of about 90% of conjugated bile salts. It extends about 13 ft (4 m), from</p><p>the jejunum (middle section of the small intestine) to the ileocecal valve,  where it joins the large intestine. Disorders produce vitamin B 12 deficiency  and extensive diarrhea (since bile salts in the large intestine interfere with  water absorption).</p><p>Iliamna \,i-le-'am-n3\ Lake Lake, Alaska, U.S. The largest lake in  Alaska and the second largest freshwater lake entirely within the U.S., it  is 80 mi (129 km) long and 25 mi (40 km) wide and covers an area of  1,000 sq mi (2,600 sq km). Located west of Cook Inlet in southwestern  Alaska, it drains southwest into Bristol Bay and the Bering Sea. The active  Iliamna Volcano, 10,016 ft (3,053 m) high, lies northeast of the lake. It  was named by Tanaina Indians, whose mythology held that it was inhab�  ited by a giant blackfish capable of biting holes in canoes.</p><p>Ilium See Troy</p><p>Illinois State (pop., 2000: 12,419,293), midwestem U.S. Bordered by  Wisconsin, Indiana, Kentucky, Missouri, and Iowa, it covers 57,918 sq  mi (150,008 sq km). Its capital is Springfield. The Mississippi River forms the  state�s western boundary, the Ohio River and Wabash River form its south�  eastern border, and the Illinois River traverses the state; Lake Michigan lies  to the northeast. Located on its northeastern border is Chicago, the  nation�s third largest city. Indian settlement dates from 8000 bc. The Mis�  sissippi culture was centred at Cahokia c. ad 1300; all the tribes inhab�  iting the area at the time of European settlement were of Algonquian stock.  The French explorers Jacques Marquette and Louis Jolliet entered the ter�  ritory in 1673. France controlled it until 1763, when it passed to Britain  after the French and Indian War. It became part of the Northwest Terri�  tory in 1783 and part of Indiana Territory in 1800; Illinois Territory was  formed in 1809, and it became the 21st state in 1818. Although politically  divided during the American Civil War, Illinois remained part of the Union.  In the 20th century, intense party rivalry (between Republicans and Demo�  crats) and the state�s large electoral vote made it a major battleground in  presidential elections (see Republican Party; Democratic Party). It is one of  the largest U.S. industrial centres and a top manufacturer of nonelectrical  machinery. It is also a major insurance centre.</p><p>Illinois Central Gulf Railroad Co. (1C) U.S. railroad formed by the  merger of the Illinois Central Railroad Co. and the Gulf, Mobile, and Ohio  Railroad Co. The Illinois Central was chartered in 1851, and its first line  was built from Galena to Cairo, Ill. A spur line to Chicago was built as  part of the acquisition of a federal land grant. It eventually absorbed more  than 100 smaller railroads across the Midwest and south to the Gulf of  Mexico. After merging with the Gulf, Mobile, and Ohio in 1972, the rail�  road operated in 13 states. In 1985 it sold its line extending from Chicago  to Iowa and Nebraska. The IC ships freight and operates passenger trains  for Amtrak. It was a subsidiary of IC Industries, Inc. (later Whitman  Corp.), a holding company formed in 1962. The railroad was privatized in  1989 and merged with Canadian National Railway Co. (CN) in 1999.</p><p>Illinois River River, northeastern Illinois, U.S. Formed by the junction  of the Des Plaines River and Kankakee River in Illinois, it flows southwest  across the state, joining the Mississippi River after a course of 273 mi (440  km).

Imag�  ism influenced the works of Conrad Aiken, T. S. Eliot, Marianne Moore,  D. H. Lawrence, Wallace Stevens, and others.</p><p>imam \i-'mam\ Head of the Muslim community. In Sunnite Islam the  imam was identical with the caliph, designating the political successor of  Muhammad. The Sunnites held the imam to be a man capable of error but  deserving obedience provided he maintained the ordinances of Islam. In  ShTite Islam the imam became a figure of absolute religious authority,  possessed of unique insights into the Qur�an and divinely appointed and  preserved from sin. With the historical disappearance of the last imam,  there arose a belief in the hidden imam, who is identified with the mahdi.  The term imam is also given to Muslims who lead prayers in mosques  and has been used as an honorary title.</p><p>Imam Bondjol Vbon-joL (b. 1772, Kampung Tandjung Bunga,  Sumatra�d. Nov. 6, 1864, Manado, Celebes) Leader in a religious war  that divided the Minangkabau people of Sumatra. A convert to reformist  Wahhabi Islam, known in Sumatra as the Padri sect, he established the  fortified community of Bondjol, from which he took his name, as a cen�  tre from which to wage holy war. The secular government called on the  Dutch to help, but the Dutch were preoccupied with the Java War (1825�  30), and Imam Bondjol�s forces expanded the area under their control.  The Dutch eventually turned their attention to the Padris and defeated  them; Imam Bondjol surrendered (1837), and the Minangkabau territory  was added to the Dutch colonial holdings.</p><p>imamis See Ithna Ashariya</p><p>Imeni Ismail Samani Peak formerly Communism Peak or  Stalin Peak Peak, western Pamirs, northeastern Tajikistan.

Dei�  fied around the time of the Persian conquest in 525 bc, he was said to be  the son of Ptah and the war goddess Sekhmet. The cult of Imhotep reached  its zenith in Greco-Roman times, when sick people slept in his temples  with the hope that the god would reveal remedies to them in dreams.</p><p>Immaculate Conception In Roman Catholicism, the dogma that Mary  was not tainted by original sin. Early exponents included St. Justin Mar�  tyr and St. Irenaeus; St. Bonaventure and St. Thomas Aquinas were among  those who opposed it. In 1439 the Council of Basel stated that the belief  was in accordance with Catholic faith, and in 1709 Pope Clement XI made  the feast of the Immaculate Conception a holy day of obligation. In 1854  Pius IX issued a papal bull making it official church dogma.

Immunity is based on the system�s  ability to launch a defense against such invaders. For the system to func�  tion properly, it must be able to distinguish between the material of its  own body (self) and material that originates outside of it (nonself). Fail�  ure to make this distinction can result in autoimmune diseases. An exagger�  ated or inappropriate response by the immune system to nonharmful  substances (e.g., pollen, animal dander) can result in allergies. The sys�  tem�s principal cells include lymphocytes that recognize antigens and</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>930 I immunity &#x25BA; impala</p><p>related accessory cells (such as phagocytic macrophages, which engulf  and destroy foreign material). Lymphocytes arise in the bone marrow from  stem cells, with T lymphocytes (T cells) migrating to the thymus to mature  and B lymphocytes (B cells) maturing in the bone marrow. Mature lym�  phocytes enter the bloodstream, and many become lodged, along with  accessory cells, in various body tissues, including the spleen, lymph nodes,  tonsils, and intestinal lining. Organs or tissues containing such concen�  trations are termed lymphoid. Within these organs and tissues the lym�  phocytes are confined within a delicate network of connective tissue that  channels them so they come into contact with antigens. T cells and B cells  can mature and multiply further in lymphoid tissue when suitably stimu�  lated. Fluid (lymph) draining from lymphoid tissues is conveyed to the  blood through lymphatic vessels. Lymph nodes distributed along these  vessels filter the lymph, exposing macrophages and lymphocytes con�  tained within to any antigen present. The spleen plays a similar role, sam�  pling the blood for the presence of antigens. The capability of  lymphocytes to pass between lymphoid tissue, the blood, and lymph is an  important element in the system�s functioning.

One part of acquired immunity, humoral immunity, involves the production of anti�  bodies by B cells. The other part, cell-mediated immunity, involves the actions of T  cells. When an antigen (such as a bacterium) enters the body, it is attacked and  engulfed by macrophages, which process and display parts of it on their cell sur�  face. A helper T cell, recognizing the antigen displayed, initiates maturation and  proliferation of other T cells. Cytotoxic (killer) T cells develop and attack foreign and  infected cells. B cells stimulated by the presence of antigen are activated by helper T  cells to divide and form antibody-producing cells (plasma cells). Released antibody  binds to antigen, marking the cell for destruction. Helper T cells also induce the  development of memory T and B cells needed to mount future immune responses on  reinfection with the same pathogen.</p><p>� MERRIAM-WEBSTER INC.</p><p>immunity Ability to resist attack or overcome infection by invading  microbes or larger parasites. Immunity is based on the proper function�  ing of the body�s immune system. In natural or innate immunity, immune  mechanisms present at birth work against a wide variety of microbes  whether or not they have been encountered before. Acquired immune  responses, tailored to act against a specific microbe or its products, are  stimulated by the prior presence of that microbe. Previous infection with  a particular pathogen, as well as vaccines, produce this type of immunity.  The mechanisms of innate immunity include physical barriers (including</p><p>the skin) and chemical barriers (such as bactericidal enzymes present in  saliva). Microbes that penetrate the body�s natural barriers encounter sub�  stances (such as interferon) that inhibit their growth or reproduction.  Phagocytes (particle-engulfing cells) surround and destroy invading  microbes, and natural killer cells pierce the microbe�s outer membrane.  Innate immunity does not confer lasting resistance, or immunity, to the  body. Acquired immunity is based on the recognition of antigen by B CELLS  and T cells and is activated when innate mechanisms are insufficient to  stem further invasion by pathogens. Killer or cytotoxic T cells destroy  infected and foreign cells. Helper T cells induce B cells stimulated by the  presence of antigen to proliferate into antibody-secreting cells, or plasma  cells. Antibodies produced by plasma cells bind to antigen-bearing cells,  marking them for destruction. Acquired immunity relies on the long-term  survival of sensitized T and B memory cells, which can proliferate quickly  upon reinfection by the same pathogen. See also immunodeficiency; immu�  nology; leukocyte; reticuloendothelial system.</p><p>immunity In law, exemption or freedom from liability. Under interna�  tional treaty, a diplomatic representative is exempt from local laws, both  civil and criminal. In many countries, judges, legislators, and government  officials, including the heads of state, enjoy limited or absolute immunity  at home to protect them from personal liability for wrongful acts or omis�  sions that arise from the performance of their duties. A public prosecutor  may grant immunity from prosecution to a witness who is suspected of  criminal activity in return for testimony against other suspected criminals.</p><p>immunodeficiency Defect in immunity that impairs the body�s ability  to resist infection. The immune system may fail to function for many rea�  sons. Immune disorders caused by a genetic defect are usually evident  early in life. Others can be acquired at any age through infections (e.g.,  AIDS) or immunosuppression. Aspects of the immune response that may be  affected include lymphocytes, other leukocytes, antibodies, and complement.  Severe combined immunodeficiency (SCID), which arises from several  different genetic defects, disrupts all of these. Depending on the cause,  treatment for immunodeficiency may be administration of immunoglob�  ulins, bone-marrow transplant, or therapy for the underlying disease.</p><p>immunology Science dealing with the body�s defenses against disease-  causing microorganisms and disorders of those defenses. Starting with  Edward Jenner�s use of a vaccine against smallpox in 1796, immunology  has arrived at a comprehensive and sophisticated understanding of the role  of microorganisms in disease and of the formation, mobilization, action,  and interaction of antibodies and antigen-reactive cells. It covers treatment  of allergies, immunosuppression after organ transplants to prevent rejection,  and study of autoimmune diseases and immunodeficiencies. AIDS has stimu�  lated intensive research in the last of these.</p><p>immunosuppression Suppression of immunity with drugs, usually to  prevent rejection of an organ transplant. Its aim is to allow the recipient  to accept the organ permanently with no unpleasant side effects. In some  cases the dosage can be reduced or even stopped without causing rejec�  tion. Other uses are in the treatment of certain autoimmune diseases and for  prevention of erythroblastosis fetalis. Its main drawback is the increased  risk of infection for the duration of treatment and of lymphoma in the case  of long-term immunosuppression.</p><p>impact test Test of the ability of a material to withstand impact, used  by engineers to predict its behaviour under actual conditions.

In the U.S. the president, vice president, and other  federal officers, including judges, may be impeached by the U.S. House of  Representatives. The House draws up articles of impeachment that itemize  the charges and their factual bases. Once approved by a majority of House  members, the articles are submitted to the Senate, which holds a trial. At its  conclusion, each member votes for or against conviction on each article;  conviction requires a two-thirds majority. A convicted official can be  removed from office. The Constitution of the United States specifies that an  officer is to be impeached for �high crimes and misdemeanors�; experts  agree that impeachment is permitted for noncriminal misconduct (e.g., vio�  lation of the Constitution). Two U.S. presidents, Andrew Johnson and Bill  Clinton, were impeached; both were acquitted. In 1974, articles of  impeachment were drawn up against Pres. Richard Nixon, who resigned  before formal proceedings could begin. In Britain, where the House of  Commons prosecutes and the House of Lords judges impeachment proceed�  ings, impeachment was formerly a means by which Parliament could get  rid of unpopular ministers, usually court favourites protected by the mon�  arch. The procedure fell into disuse in the early 19th century, when cabinet  ministers became responsible to Parliament rather than to the sovereign.</p><p>Imperial Chemical Industries PLC (ICI) Major British chemical  corporation. It was founded in 1926 as Imperial Chemical Industries Ltd.  to amalgamate four major British chemical companies. Between World  Wars I and II, ICI was a major competitor of IG Farben.

ICI�s headquarters are in London.</p><p>Imperial Conferences Periodic meetings held between 1907 and  1937 by the dominions within the British Empire and later the Common�  wealth. Convened to discuss mutual defense and economic issues, they  passed nonbinding resolutions. However, the Statute of Westminster imple�  mented decisions made at the 1926 and 1930 conferences that described  the self-governing dominions (Canada, Australia, New Zealand, South  Africa, Ireland, and Newfoundland) as �autonomous communities within  the British empire.� After World War II, meetings between the countries�  prime ministers replaced the conferences.</p><p>Imperial Valley Valley extending from southeastern California, U.S.,  to Mexico. It forms part of the Colorado Desert. Intensive irrigation began  in 1901 with the opening of the Imperial Canal, which diverted water from  the Colorado River.

With 3,000 mi (4,800 km) of irrigation  canals, it contains 500,000 acres (200,000 hectares) of cultivated land.</p><p>imperialism State policy, practice, or advocacy of extending power and  dominion, especially by direct territorial acquisition or by gaining political  and economic control of other areas. Because imperialism always involves  the use of power, often in the form of military force, it is widely considered  morally objectionable, and the term accordingly has been used by states to  denounce and discredit the foreign policies of their opponents. Imperialism  in ancient times is clear in the unending succession of empires in China,  western Asia, and the Mediterranean. Between the 15th century and the  middle of the 18th, England, France, the Netherlands, Portugal, and Spain  built empires in the Americas, India, and the East Indies. Russia, Italy, Ger�  many, the United States, and Japan became imperial powers in the period  from the middle of the 19th century to World War I. The imperial designs  of Japan, fascist Italy, and Nazi Germany in the 1930s culminated in the  outbreak of World War II. After the war the Soviet Union consolidated its  military and political control of the states of eastern Europe (see Iron Cur�</p><p>tain). From the early 20th century the U.S. was accused of imperialism for  intervening in the affairs of developing countries in order to protect the  interests of U.S.-owned international corporations (see United Fruit Co.).  Economists and political theorists have debated whether imperialism ben�  efits the states that practice it and whether such benefits or other reasons  ever justify a state in pursuing imperialist polices. Some theorists, such as  Niccolo Machiavelli, have argued that imperialism is the justified result of  the natural struggle for survival among peoples. Others have asserted that  it is necessary in order to ensure national security. A third justification for  imperialism, offered only infrequently after World War II, is that it is a  means of liberating peoples from tyrannical rule or bringing them the bless�  ings of a superior way of life.

It was the seat of the kings of Manipur before the region came under Brit�  ish rule. In 1944 it was the site of a victory for the Anglo-Indian forces  over the Japanese on the Burmese front. Imphal is a major trade centre,  noted for its weaving, brass ware, and bronze ware.</p><p>implication In logic, a relation that holds between two propositions  when they are linked as antecedent and consequent of a true conditional  proposition. Logicians distinguish two main types of implication, mate�  rial and strict. Proposition p materially implies proposition q if and only  if the material conditional p z&gt; q (read �if p then q �) is true. A proposi�  tion of the form p q is false whenever p is true and q is false; it is true  in the other three possible cases (i.e., p true and q true; p false and q true;  p false and q false). It follows that whenever p is false, p z&gt; q is auto�  matically true: this is a peculiarity that makes the material conditional  inadequate as an interpretation of the meaning of conditional sentences  in ordinary English. On the other hand, proposition p strictly implies  proposition q if and only if it is impossible for p to be true without q also  being true (i.e., if the conjunction of p and not-# is impossible).</p><p>impotence Vim-po-tonsV Inability to achieve or maintain erection of the  penis; hence, inability to participate fully in sexual intercourse. Erectile  impotence (failure to achieve erection) may have either physical causes  (e.g., alcoholism, endocrine disease) or psychological ones (e.g., anxiety,  hostility toward the partner). Ejaculatory impotence (inability to reach  orgasm, sometimes with an erection maintained for a long time) nearly  always has an emotional cause. See also Viagra.</p><p>Impressionism Movement in art that developed in France in the late  19th century. In painting it included works produced c. 1867-86 by a  group of artists who shared approaches, techniques, and discontent with  academic teaching, originally including Claude Monet, Pierre-Auguste  Renoir, Camille Pissarro, Alfred Sisley, and Berthe Morisot. Later Edouard  Manet, whose earlier style had strongly influenced several of them, Mary  Cassatt, Edgar Degas, Paul Cezanne and others joined them. The identi�  fying feature of their work was an attempt to record a scene accurately  and objectively, capturing the transient effects of light on colour and tex�  ture. To this end they abandoned the traditional muted browns, grays, and  greens in favour of a lighter, more brilliant palette; stopped using grays  and blacks for shadows; built up forms out of discrete flecks and dabs of  colour; and often painted out of doors, rather than in the studio. They  abandoned traditional formal compositions in favour of a more casual and  less contrived disposition of objects within the picture frame, and their  subject matter included landscapes, trees, houses, and even urban street  scenes and railroad stations. After the French Academy�s Salon consis�  tently rejected most of their works, they held their own exhibition in 1874;  seven others followed. A critic described them derisively as �impression�  ists,� and they adopted the name as an accurate description of their intent.  Before dissolving in the late 1880s, the group had revolutionized West�  ern painting. See also Post-Impressionism; Salon des Independants.</p><p>Impressionism In music, a style initiated by French composer Claude  Debussy at the end of the 19th century. The term, which is somewhat vague  in reference to music, was introduced by analogy with contemporaneous</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>932 I impressment &#x25BA; incest</p><p>French painting; it was disliked by Debussy himself. Elements often  termed impressionistic include static harmony, emphasis on instrumental  timbres that creates a shimmering interplay of �colours,� melodies that  lack directed motion, surface ornamentation that obscures or substitutes  for melody, and an avoidance of traditional musical form. Impressionism  can be seen as a reaction against the rhetoric of Romanticism, disrupting  the forward motion of standard harmonic progressions. The other com�  poser most often associated with Impressionism is Maurice Ravel. Impres�  sionistic passages are common in earlier music by Frederic Chopin, Franz  Liszt, and Richard Wagner, and in music by later composers such as Charles  Ives, Bela Bartok, and George Gershwin.</p><p>impressment Enforcement of military or naval service on unwilling  men. Until the early 19th century, it flourished in port towns everywhere,  as �recruiters� searched through waterfront boardinghouses, brothels, and  taverns. They often chose vagabonds or prisoners. Impressed men were  forced into service through violence or coercion and were held to their  duty by brutal discipline. In the early 19th century, Royal Navy ships halt�  ing U.S. vessels to search for British deserters frequently impressed natu�  ralized U.S. citizens, one cause of the War of 1812. Impressment  declined in the 19th century as states adopted more systematic recruiting  methods. See also conscription.</p><p>imprinting Form of learning wherein a very young animal fixes its  attention on the first object with which it has visual, auditory, or tactile  experience and thereafter follows that object. In nature, the object is  almost always a parent; in experiments, other animals and inanimate  objects have been used. Imprinting has been studied extensively only in  birds, but a comparable form of learning apparently takes place among  many mammals and some fishes and insects. Ducklings and chicks, which  can imprint in a few hours, lose receptivity to imprinting stimuli within  30 hours of hatching.</p><p>improvisation Creation of music in real time. Improvisation usually  involves some preparation beforehand, particularly when there is more  than one performer. Despite the central place of notated music in the  Western tradition, improvisation has often played a role, from the earli�  est organum through the use of continuo (partially improvised accompa�  niment played on a bass line) in the 17th and 18th centuries. It has taken  forms such as creation of a melody over a bass line for dancing, elabo�  rate ornamentation added to a repeated section in an aria, keyboard varia�  tions on popular songs, concerto cadenzas, and free solo fantasias. Perhaps  at its lowest ebb in the 19th century, improvisation returned to concert  music in �experimental� compositions and in �authentic� performances  of older music. Its most important contemporary Western form is jazz. It  is also a defining feature of the raga.</p><p>in vitro fertilization (IVF) \in-'ve-tro\ or test-tube conception</p><p>Procedure, used to overcome infertility, in which eggs are removed from  a woman, fertilized with sperm outside the body, and inserted into the uterus  of the same or another woman. The first child thus conceived was bom  in 1978. IVF includes extraction of eggs, collection of sperm, fertiliza�  tion in culture, and introduction into  the uterus at the eight-cell stage. In  a successful procedure, the embryo  is implanted in the uterine wall, and  pregnancy begins. The most com�  mon problem is failed implantation.</p><p>IVF has been a source of moral, ethi�  cal, and religious controversy since  its development.</p><p>Inari \e-'na-re\ In Japanese mythol�  ogy, the patron god of rice cultiva�  tion and prosperity. He was  worshiped especially by merchants  and tradesmen, and he also served as  patron deity of swordsmiths, broth�  els, and entertainers. Inari was vari�  ously depicted as a bearded old man  riding a fox or as a woman with long  hair, carrying sheaves of rice. The  fox is sometimes identified as his  messenger. The god�s most popular  shrine is the Fushimi Inari Shrine  near Kyoto.</p><p>inbreeding Mating of closely related individuals. The opposite is out-  breeding, the mating of unrelated organisms. Inbreeding is useful in keep�  ing desirable characteristics or eliminating undesirable ones, but it often  results in decreased vigour, size, and fertility of the offspring because of  the combined effect of harmful genes that were recessive in both parents  (see recessiveness). The closest type of inbreeding is self-fertilization. In  linebreeding, mates are selected on the basis of their relationships to a  certain superior ancestor. The backcross (crossing a first-generation  hybrid with one of the parental types) is a common method of inbreed�  ing.</p><p>Inca Group of South American Indians who ruled an empire that  extended along the Pacific coast and Andes Mountains from what is now  northern Ecuador to central Chile. According to tradition (the Inca left no  written records), the founder of the Incan dynasty led the tribe to Cuzco,  which became their capital. Under the fourth emperor, they began to  expand, and under the eighth they began a program of permanent con�  quest by establishing garrisons among the conquered peoples. Under Topa  Inca Yupanqui and his successor, the empire reached its southernmost and  northernmost extent. By the early 16th century the Inca controlled an  empire of some 12 million subjects. They constructed a vast network of  roads, their architecture was highly developed, and the remains of their  irrigation systems, palaces, temples, and fortifications are still in evidence  throughout the Andes. Incan society was highly stratified and featured an  aristocratic bureaucracy. Their pantheon, worshiped in a highly organized  state religion, included a sun god, a creator god, and a rain god. The Incan  empire was overthrown in 1532 by the Spanish coNQUiSTADORes, who made  great use of the Incan road system during their conquests. The Inca�s  descendants are the Quechua-speaking peasants of the Andes (see Que-  chua). In Peru nearly half the population is of Incan descent. They are  primarily farmers and herders living in close-knit communities. Their  Roman Catholicism is infused with belief in pagan spirits and divinities.

In an electric incandes�  cent lamp, or lightbulb, a filament is enclosed in a glass shell that is either  evacuated or filled with an inert gas. The filament gives off light when  heated by an electric current. The first practical electric incandescent  lamps were independently produced in the late 1870s by Joseph Swan and  Thomas Alva Edison. Edison has received the major credit because of his  development of the power lines and other equipment needed for a light�  ing system. Inefficient in comparison with fluorescent lamps and electric  discharge lamps, incandescent lighting is today reserved mainly for domes�  tic use. See also halogen lamp.</p><p>Incarnation Central Christian doctrine that God became man in the  form of Jesus, the son of God and the second person of the Holy Trinity.  In Jesus the divine and human nature are joined but neither is changed or  diminished. This difficult doctrine gave rise to a variety of heresies, some  denying Jesus�s divine nature, others his human nature. For orthodox  believers the conflict was settled at the Councils of Nicaea (ad 325) and  Chalcedon (ad 451).</p><p>incense Grains of resins (sometimes mixed with spices) that burn with  a fragrant odor, widely used as religious offerings. Historically, the chief  substances used as incense have been resins such as frankincense and  myrrh, along with fragrant wood and bark, seeds, roots, and flowers.</p><p>incest Sexual relations between persons who, because of the nature of  their kinship ties, are prohibited by law or custom from intermarrying. The  incest taboo is generally universal, although it is imposed differently in  different societies. Usually, the closer the genetic relationship between  two people, the stronger and more highly charged is the taboo prohibit�  ing or discouraging sexual relations. Some sociobiologists consider that  inbred populations have diminished reproductive success and become  gene pools for hereditary disorders. Some cultural anthropologists argue  instead that the incest prohibition, with the corresponding rules of  exogamy, acts to require males to seek sexual and marital partners outside  the group, thereby establishing useful alliances. Other theories emphasize  the need to control sexual jealousies within the family or to prepare chil�  dren to function with restraint in adult society. No single explanation  seems satisfactory, causing some to question whether incest should be  treated as a unitary subject. Most cases of incest that come before crimi�  nal courts concern sexual intercourse between fathers and relatively young  daughters (see child abuse).</p><p>Inari, wood figurine, Tokugawa period  (1603-1867); in the Musee Guimet,  Paris</p><p>COURTESY OF THE MUSEE GUIMET, PARIS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>inch &#x25BA; India I 933</p><p>inch Unit of measure equal to 1/36 yard and since 1959 defined officially  as 2.54 cm (see metre).

The practice  dates back to ritualistic Greek drama, and it is thus connected to the use  of music in other kinds of ritual. Sometimes limited to the role of intro�  duction or interlude (setting a mood or a historical period, for example),  it may also accompany spoken dialogue (see melodrama). Film and tele�  vision music is sometimes considered incidental music.</p><p>Inclan, Ramon Maria del Valle- See Ramon Maria del Valle-InclAn</p><p>income statement In accounting, the activity-oriented financial state�  ment issued by businesses. Covering a specified time, such as three  months or one year, the income statement is a summary of revenues and  expenses. It also lists gains and losses from other transactions, such as the  sale of assets or the repayment of debt. Standard accounting rules govern  the procedures for recording each item.</p><p>income tax Levy imposed by public authority on the incomes of per�  sons or corporations within its jurisdiction. In nations with an advanced  system of private enterprise, income taxes represent the chief source of  government revenue. Income tax levied on individuals or family units is  known as personal income tax. In 1799 Britain enacted a general income  tax to finance the Napoleonic Wars. In the U.S. an income tax was first  tried during the Civil War; the Supreme Court held it to be constitutional  in 1881 but declared another income tax unconstitutional in 1894. In 1913  the 16th Amendment to the Constitution made the personal income tax  permanent. The fairness of personal income taxation is based on the  premise that one�s income is the best single index of one�s ability to con�  tribute to the support of the government; most personal income taxes are  conceived on the theory that when people�s financial circumstances dif�  fer, their tax liabilities should also differ. Thus U.S. income taxes are pro�  gressive TAXes, falling more heavily on those who earn more money, and  individual income tax deductions are allowed for items such as interest  paid on home mortgage debt, unusual medical expenses, philanthropic  contributions, and state and local income and property taxes. Enforcement  has been facilitated by withholding the tax from wages and salaries. See  also CAPITAL GAINS TAX; CAPITAL LEVY; CORPORATE INCOME TAX; REGRESSIVE TAX; SALES</p><p>tax; value-added tax.</p><p>incomes policy Collective governmental effort to control the incomes  of labour and capital, usually by limiting increases in wages and prices. The  term often refers to policies directed at the control of inflation, but it may  also indicate efforts to alter the distribution of income among workers,  industries, locations, or occupational groups. See also wage-price control.</p><p>incontinence Inability to control excretion. Starting and stopping uri�  nation relies on normal function in pelvic and abdominal muscles, dia�  phragm, and control nerves. Babies� nervous systems are too immature  for urinary control. Later incontinence may reflect disorders (e.g., neural  tube defect causing �neurogenic bladder�), paralysis of urinary system  muscles, long-term bladder distension, or certain urogenital malforma�  tions. Weak pelvic muscles can allow small urine losses on coughing or  sneezing (�stress incontinence�). Uncontrolled defecation can result from  spinal or bodily injuries, old age, extreme fear, or severe diarrhea.

In fiscal policy, index�  ation is used as a means of offsetting the effect of inflation or deflation  on social security payments and taxes by measuring the real value of money  from a fixed point of reference, usually a price index. Without indexing,  recipients of social security benefits, for example, would suffer during  times of inflation if their benefits remained at a fixed rate. Indexation is  used in some countries to offset �bracket creep,� which occurs in any pro�  gressive tax system when inflation pushes taxpayers into higher tax brack�  ets.

India has  been inhabited for thousands of  years. Agriculture in India dates to  the 7th millennium bc, and an urban  civilization, that of the Indus valley,  was established by 2600 bc. Buddhism  and Jainism arose in the 6th century  bc in reaction to the caste-based soci�  ety created by the Vedic religion and  its successor, Hinduism. Muslim  invasions began c. ad 1000, estab�  lishing the long-lived Delhi sultanate  in 1206 and the Mughal dynasty in  1526. Vasco da Gama�s voyage to  India in 1498 initiated several centuries of commercial rivalry between  the Portuguese, Dutch, English, and French. British conquests in the 18th  and 19th centuries led to the rule of the British East India Co., and direct  administration by the British Empire began in 1858. After Mohandas K.  Gandhi helped end British rule in 1947, Jawaharlal Nehru became India�s  first prime minister, and Nehru, his daughter Indira Gandhi, and his grand�  son Rajiv Gandhi guided the nation�s destiny for all but a few years until  1991. The subcontinent was partitioned into two countries�India, with  a Hindu majority, and Pakistan, with a Muslim majority�in 1947. A later  clash with Pakistan resulted in the creation of Bangladesh in 1971. In the  1980s and �90s, Sikhs sought to establish an independent state in Punjab,  and ethnic and religious conflicts took place in other parts of the country  as well.

They were shackled and imprisoned, but their outraged  comrades shot their British officers and marched on Delhi. The ensuing  fighting was ferocious on both sides and ended in defeat for the muti�  neers. Its immediate result was that the East India Company was abol�  ished in favour of direct rule of India by the British government; in  addition, the British government began a policy of consultation with Indi�  ans.

During World War II, the party  announced that India would not support the war until granted complete  independence. In 1947 an Indian independence bill became law, and in  1950 the constitution took effect. Jawaharlal Nehru dominated the party  from 1951 to 1964.

The history of Indian philosophy may be divided  into three periods: the prelogical (to the beginning of the Christian era),  the logical (lst-llth century), and the ultralogical (11th�18th century).  What Dasgupta calls the prelogical stage covers the pre-Mauryan and the  Mauryan periods (c. 321-185 bc) in Indian history. The logical period  begins roughly with the Kusanas (1 st-2nd century ad) and was developed  most fully in the Gupta era (3rd-5th century) and in the age of imperial  Kanauj (7th century). In the 19th century, newly founded universities  introduced Indian intellectuals to Western thought, particularly British  empiricism and utilitarianism. Indian philosophy in the early 20th century was  influenced by German idealism. Later Indian philosophers made significant  contributions to analytic philosophy.</p><p>Indian pipe Nongreen herbaceous plant (Monotropa uniflora ) that is  saprophytic (living on the remains of dead plants).

It gave Indians the power to manage their inter�  nal affairs and established a revolving credit fund for tribal land purchases  and educational assistance. It remains the basic legislation concerning  Indian affairs.</p><p>Indian Territory Former territory, U.S. West, including most of mod�  em Oklahoma. The Choctaw, Creek, Seminole, Cherokee, and Chickasaw  tribes were forcibly moved to this area between 1830 and 1843, and an  1834 act set aside the land as Indian country. In 1866 its western half was  ceded to the U.S.; this portion was opened to white settlers in 1889 and  became the Territory of Oklahoma in 1890.

Its capital is Indianapolis. The Wabash River and the Ohio River  define its southwestern and southern borders, respectively; Lake Michi�  gan lies to the northwest. Indiana was originally inhabited by Indians  speaking Algonquian languages, including the Miami, Potawatomi, and  Delaware peoples. The French explorer La Salle explored the region in  1679 and claimed it for France. It passed to Britain in 1763 and then to  the U.S. in 1783, and it became a territory in 1800. In 1811 U.S. forces  won a final victory over the Indians at the Battle of Tippecanoe. After it</p><p>was admitted to the Union as the 19th state in 1816, its population began  to grow. From 1850 its agriculture expanded, as did industrialization after  the American Civil War. For much of the 20th century, steelmaking (see  Gary) was important economically.</p><p>Indiana, Robert orig. Robert Clark (b. Sept. 13,1928, New Castle,  Ind., U.S.) U.S. painter, sculptor, and graphic artist. After studies at the  Art Institute of Chicago, he settled in New York City and became a lead�  ing exponent of Pop art. He achieved wide recognition for paintings and  prints featuring geometric shapes emblazoned with lettering and vivid  colours. In 1964 he collaborated with Andy Warhol on the film Eat and  was commissioned to produce an EAT sign for the New York pavilion at  the New York World�s Fair. His most famous image, LOVE, first lettered  on canvas in 1965, became a universal symbol for the hippie generation.</p><p>Indiana Dunes State park and national lakeshore, southern shore of  Lake Michigan, northern Indiana, U.S. The state park (founded 1925)  comprises 2,182 acres (883 hectares) of shoreline, marshland, dunes, and  forests. At the Big Blowout in the eastern end of the park, lake winds drift  sands over a wooded area, creating a �graveyard of trees�; the dunes may  reach heights of 200 ft (60 m). The national lakeshore (founded 1966)  encloses the state park on three sides.

It is a hub of road, rail, and  air transportation. It is a leading grain market and an industrial centre,  with manufactures including pharmaceuticals, machinery, and transpor�  tation and electrical equipment.

Aside from  the Kharoshthi (Kharosthi) script, used c. 4th century BC-3rd century ad,  all extant writing of the region descends from the Brahmi script, first  attested in the Middle Indo-Aryan rock inscriptions of Ashoka (3rd cen�  tury bc). In the first six centuries after Ashoka, Brahmi appears to have  diversified into northern and southern variants. The northern types gave  rise to the so-called Gupta scripts (4th-5th centuries), which are ultimately  the progenitors of the Devanagari script (now used to write Sanskrit, Hindi,  Marathi, and Nepali), the Bengali and Oriya scripts, and Gurmukhi, the  script of the Sikh scriptures, used also for modern Punjabi in India. The  southern types gave rise to the Sinhalese, Telugu, and Kannada scripts on  the one hand, and to the Pallava script on the other. The latter formed the  basis of numerous other scripts, including those of the Tamil and Malay-  alam languages, a host of Southeast Asian scripts (e.g., those used to write  Mon, Burmese, Khmer, Thai, and Lao), and a number of Austronesian lan�  guages.</p><p>indicator, economic See economic indicator</p><p>indictment In criminal law, a formal written accusation of a crime  affirmed by a grand jury and handed up to the court for trial of the accused.

Its adherents draw a sharp distinction between Indi�  ans and people of European ancestry, who have dominated the Indian  majorities since the 16th-century Spanish and Portuguese conquest. The  movement became influential in Mexico with the revolution of 1910-20;  it was particularly strong during the presidency of Lazaro Cardenas (1934�  40), who made serious efforts to reconstitute the country in accordance  with its Indian heritage. In Peru it is associated with the APRA move�  ment.</p><p>indigo \'in-di-,go\ Blue vat dye, obtained until about 1900 entirely from  some species of the indigo plant. Extraction of the dye was important to  the economy of colonial America and remained so in India until the early  20th century. Synthetic indigo has replaced the natural dye; it is reduced  chemically to the soluble yellow compound leucoindigo, in which form  it is applied to textile fibres and reoxidized to indigo (see oxidation-  reduction).</p><p>indigo plant Any shrub or herb in the genus Indigofera of the pea  family (see legume). Most occur in warm climates and are silky or hairy.  The leaves are usually divided into smaller leaflets. Small rose, purple,  or white flowers are borne in spikes or clusters. The fruit is a pod.

The largest snake in  the U.S., it has a record length of 9.2 ft (2.8 m). In the U.S. it is blue-  black; southward it may have brown foreparts, and in the tropics it is often  called brown snake. It kills small vertebrates, including venomous snakes,  by crushing with its jaws and the weight of its coils, but is not a con�  strictor. In defense it hisses and vibrates its tail but rarely strikes. It may  share a burrow with a gopher tortoise, for which it is often called gopher  snake.

Of a brilliant, silvery-white lustre, it is so soft that it can be scratched  with a fingernail. Its most common isotope, indium-115, is very weakly  radioactive, with a half-life measured in billions of years. Like tin, the pure  metal emits a high-pitched �cry� when bent, and, like gallium, molten  indium wets glass and other surfaces, which makes it valuable for pro�  ducing seals between glass, metals, quartz, ceramics, and marble. The  metal is used in coating high-performance engine bearings and is an ingre�  dient in low-melting-point alloys for sprinkler heads, fire-door links, and  fusible plugs. In various combinations with elements such as gallium,  phosphorus, and arsenic, it forms compounds having semiconductor prop�  erties useful in electronics, including solid-state light-emitting devices.  Transparent electrodes made from an oxide of indium and tin are widely  employed in liquid crystal displays.</p><p>individualism Political and social philosophy that emphasizes indi�  vidual freedom. Modern individualism emerged in Britain with the ideas  of Adam Smith and Jeremy Bentham, and the concept was described by Alexis  de Tocqueville as fundamental to the American temper. Individualism</p><p>encompasses a value system, a theory of human nature, and a belief in  certain political, economic, social, and religious arrangements. According  to the individualist, all values are human-centred, the individual is of  supreme importance, and all individuals are morally equal. Individualism  places great value on self-reliance, on privacy, and on mutual respect.  Negatively, it embraces opposition to authority and to all manner of con�  trols over the individual, especially when exercised by the state. As a  theory of human nature, individualism holds that the interests of the nor�  mal adult are best served by allowing him maximum freedom and respon�  sibility for choosing his objectives and the means for obtaining them. The  institutional embodiment of individualism follows from these principles.  All individualists believe that government should keep its interference in  the lives of individuals at a minimum, confining itself largely to main�  taining law and order, preventing individuals from interfering with oth�  ers, and enforcing agreements (contracts) voluntarily arrived at.  Individualism also implies a property system according to which each  person or family enjoys the maximum of opportunity to acquire property  and to manage and dispose of it as he or they see fit. Although economic  individualism and political individualism in the form of democracy  advanced together for a while, in the course of the 19th century they  eventually proved incompatible, as newly enfranchised voters came to  demand governmental intervention in the economic process. Individual�  istic ideas lost ground in the later 19th and early 20th century with the  rise of large-scale social organization and the emergence of political theo�  ries opposed to individualism, particularly communism and fascism. They  reemerged in the latter half of the 20th century with the defeat of fascism,  the fall of communism in the Soviet Union and eastern Europe, and the  worldwide spread of representative democracy. See also libertarianism.</p><p>individuation Determination that an individual identified in one way  is numerically identical with or distinct from an individual identified in  another way (e.g., Venus, known as �the morning star� in the morning  and �the evening star� in the evening). Since the concept of an individual  seems to require that it be recognizable as such in several possible situ�  ations, the problem of individuation is of great importance in ontology  and logic. The problem of identifying an individual existing at two dif�  ferent times (transtemporal identity) is one of many forms that the prob�  lem of individuation can take: What makes that caterpillar identical with  this butterfly? What makes the person you are now identical with the per�  son you were a decade ago? In modal logic, the problem of transworld  individuation (or transworld identity) is of importance because the stan�  dard model of theoretic semantics for systems of modal logic assumes  that it makes sense to speak of the same individual existing in more than  one possible world.</p><p>Indo-Aryan languages or Indie languages Major subgroup of  the Indo-Iranian branch of the Indo-European language family. Indo-Aryan  languages are spoken by more than 800 million people, principally in  India, Nepal, Pakistan, Bangladesh, and Sri Lanka. The Old Indo-Aryan  period is represented by Sanskrit. Middle Indo-Aryan (c. 600 bc-ad 1000)  consists principally of the Prakrit dialects, including Pali. Modern Indo-  Aryan speech is largely a single dialect continuum spread over an undi�  vided geographical space, so demarcations between languages and  dialects are somewhat artificial. Complicating the situation are compet�  ing distinctions between languages with an old literary tradition, local  language identification by native speakers (as in censuses), supraregional  languages such as Modern Standard Hindi and Urdu, and labels introduced  by linguists, particularly those of George Abraham Grierson. In the centre  of the Indo-Aryan speech area (the �Hindi zone�), covering northern India  and extending south as far as Madhya Pradesh, the most common lan�  guage of administration and education is Modem Standard Hindi. Impor�  tant regional languages in the northern Indian plain are Haryanvi, Kauravi,  Braj, Awadhi, Chhattisgarhi, Bhojpuri, Magahi, and Maithili. Regional  languages in Rajasthan include Marwari, Dhundhari, Harauti, and Malvi.  In the Himalayan foothills of Himachal Pradesh are Grierson�s Pahari  languages. Surrounding the Hindi zone, the most significant languages  are, moving clockwise, Nepali (East Pahari), Assamese, Bengali, Oriya,  Marathi, Gujarati, Sindhi, the speech of southern, northwestern, and  northern Punjab province in Pakistan (called West Punjabi or Lahnda by  Grierson), Punjabi, and Dogri. In Jammu and Kashmir and the far north of  Pakistan are the Dardic languages; the most important are Kashmiri,  Kohistani, Shina, and Khowar. The Nuristani languages of northwestern  Afghanistan are sometimes considered a separate branch of Indo-Iranian.  Sinhalese (spoken in Sri Lanka), Divehi (spoken in the Maidive Islands),  and Romany are also Indo-Aryan languages.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Indo-European languages &#x25BA; induction I 937</p><p>Indo-European languages Family of languages with the greatest  number of speakers, spoken in most of Europe and areas of European  settlement and in much of southwestern and southern Asia. They are  descended from a single unrecorded language believed to have been spo�  ken more than 5,000 years ago in the steppe regions north of the Black  Sea and to have split into a number of dialects by 3000 bc. Carried by  migrating tribes to Europe and Asia, these developed over time into sepa�  rate languages. The main branches are Anatolian, Indo-Iranian (including  Indo-Aryan and Iranian), Greek, Itauc, Germanic, Armenian, Celtic, Alba�  nian, the extinct Tocharian languages, Baltic, and Slavic. The study of  Indo-European began in 1786 with Sir William Jones�s proposal that  Greek, Latin, Sanskrit, Germanic, and Celtic were all derived from a  �common source.� In the 19th century linguists added other languages to  the Indo-European family, and scholars such as Rasmus Rask established  a system of sound correspondences. Proto-Indo-European has since been  partially reconstructed via identification of roots common to its descen�  dants and analysis of shared grammatical patterns.</p><p>Indo-Gangetic Plain See Gangetic Plain</p><p>Indochina or Indochinese Peninsula Region of mainland South�  east Asia. The term, now largely superseded by the name Southeast Asia,  was used mainly by Westerners to describe the intermingling of Indian  and Chinese cultural influences in the region.

The first conflict (1946-54; often called the French Indochina War)  involved France, which had ruled Vietnam as its colony (French Indoch�  ina), and the newly independent Democratic Republic of Vietnam under  Ho Chi Minh; the war ended in Vietnamese victory in 1954. Vietnam was  then divided into the communist-dominated north and the U.S.-supported  south; war soon broke out between the two. North Vietnam won the war  (the Vietnam War) despite heavy U.S. involvement, and the country was  reunited in 1976. Cambodia experienced its own civil war between com�  munists and noncommunists during that period, which was won by the  communist Khmer Rouge in 1975. After several years of horrifying atroci�  ties under Pol Pot, the Vietnamese invaded in 1979 and installed a pup�  pet government. Fighting between the Khmer Rouge and the Vietnamese  continued throughout the 1980s; Vietnam withdrew its troops by 1989. In  1993 UN-mediated elections established an interim government, and  Cambodia�s monarchy was reestablished. In Laos, North Vietnam�s vic�  tory over South Vietnam brought the communist Pathet Lao into com�  plete control in Laos.</p><p>Indonesia officially Republic of Indonesia formerly Nether�  lands East Indies Archipelago country, located off the coast of main�  land Southeast Asia. It comprises some 17,500 islands, of which about  6,000 are uninhabited. Area: 730,024 square miles (1,890,754 square km).  Population (2005 est.): 222,781,000. Capital: Jakarta (on Java). Indone�  sia has more than 300 ethnic groups, which in the western islands fall into  three broad divisions: the inland rice-growing peoples of Java and neigh�  bouring islands; the Muslim coastal peoples, including the Malays of  Sumatra; and the Dayak and other tribal groups. In the east the distinc�  tion is between coastal and interior peoples. Languages: Bahasa Indone�  sia (official), some 250 languages from different ethnic groups. Religions:  Islam; also Christianity, Hinduism, traditional beliefs. Currency: rupiah.  The Indonesian archipelago stretches 3,200 miles (5,100 km) from west  to east. Major islands include Sumatra, Java (with more than half of Indo�  nesia�s population), Bali, Lombok, Sumbawa, about three-fourths of Borneo  (Kalimantan), Celebes (Sulawesi), the Moluccas, and the western portions  of Timor and New Guinea. The islands are characterized by rugged vol�  canic mountains and tropical rainforests. Geologically unstable, Indone�  sia has frequent earthquakes and 220 active volcanoes, including Krakatoa  (Krakatau). Roughly one-fifth of its land is arable, and rice is the staple  crop. Petroleum, natural gas, timber products, garments, and rubber are  major exports. Indonesia is a republic with two legislative houses; its head  of state and government is the president.</p><p>Austronesian-speaking peoples began migrating to Indonesia about the  3rd millennium bc. Commercial relations were established with Africa  about the 1st century ad, and Hindu and Buddhist cultural influences from  India began to take hold. Indian traders also brought Islam to the islands,  and by the 13th century it was spreading throughout the islands�except  Bali, which retained its Hindu religion and culture. Indonesia now has the</p><p>largest Muslim population of any country. European influence began in  the 16th century, and the Dutch gradually established control of Indone�  sia from the late 17th century until 1942, when the Japanese invaded.  Sukarno declared Indonesia�s independence in 1945, which the Dutch  granted, with nominal union to The Netherlands, in 1949; Indonesia dis�  solved this union in 1954. The suppression of an alleged coup attempt in  1965 resulted in the deaths of hundreds of thousands of people the gov�  ernment claimed to be communists, and by 1968 Gen. Suharto had taken  power. His government forcibly incorporated East Timor into Indonesia in  1975-76, with much loss of life. In the 1990s the country was beset by  political, economic, and environmental problems, and Suharto was  deposed in 1998. Muslim leader Abdurrahman Wahid was elected presi�  dent in 1999 but was replaced in 2001 by his vice president, Megawati  Sukarnoputri, the eldest daughter of Sukarno. In 2004 she was succeeded  by Susilo Bambang Yudhoyono. In 1999 the people of East Timor voted  for independence from Indonesia, which was granted; after a period under  UN supervision, it achieved full sovereignty in 2002. In 2004 a large tsu�  nami generated by an earthquake off the western coast of Sumatra caused  widespread death and destruction.

A steadily changing electric current produces a  varying magnetic field, which induces an emf in a conductor that is present  in the field. The magnitude of this voltage is proportional to the rate of  change of the current. The inductance is the proportionality factor. The  unit of inductance is the henry, named after Joseph Henry; one henry is  equivalent to one volt divided by one ampere per second.</p><p>induction In logic, a type of nonvalid inference or argument in which  the premises provide some reason for believing that the conclusion is true.  Typical forms of inductive argument include reasoning from a part to a  whole, from the particular to the general, and from a sample to an entire  population.

(1) If we were asked why we believe  that the sun will rise tomorrow, we would say that in the past the Earth  turned on its axis every 24 hours (more or less), and that there is a uni�  formity in nature that guarantees that such events always happen in the  same way. But how do we know that nature is uniform in this sense? We  might answer that, in the past, nature has always exhibited this kind of  uniformity, and so it will continue to be uniform in the future.

How do  we justify this assumption? We might say  that in the past, the future turned out to  resemble the past, and so in the future, the future will again turn out to  resemble the past. The inference is obviously circular: it succeeds only  by tacitly assuming what it sets out to prove, namely that the future will  resemble the past. (2) If we are asked why we believe we will feel heat  when we approach a fire, we would say that fire causes heat�i.e., there  is a �necessary connection� between fire and heat, such that whenever  one occurs, the other must follow. But, Hume asks, what is this �neces�  sary connection�? Do we observe it when we see the fire or feel the heat?  If not, what evidence do we have that it exists? All we have is our obser�  vation, in the past, of a �constant conjunction� of instances of fire being  followed by instances of heat. This observation does not show that, in the  future, instances of fire will continue to be followed by instances of heat;  to say that it does is to assume that the future must resemble the past. But  if our observation is consistent with the possibility that fire may not be  followed by heat in the future, then it cannot show that there is a neces�  sary connection between the two that makes heat follow fire whenever  fire occurs. Thus we are not justified in believing that (1) the sun will rise  tomorrow or that (2) we will feel heat when we approach a fire. It is  important to note that Hume did not deny that he or anyone else formed  beliefs about the future on the basis of induction; he denied only that we  could know with certainty that these beliefs are true. Philosophers have  responded to the problem of induction in a variety of ways, though none  has gained wide acceptance.</p><p>induction heating Method of raising the temperature of an electri�  cally conductive material by subjecting it to an alternating electromagnetic  field. Energy in the electric currents induced in the object is dissipated as  heat. Induction heating is used in metalworking to heat metals for solder�  ing, tempering, and annealing, and in induction furnaces for melting and  processing metals. The principle of the induction-heating process  resembles that of the transformer. A water-cooled coil (inductor), acting  as the primary winding of a transformer, surrounds the material to be  heated (the workpiece), which acts as the secondary winding. Alternating  current flowing in the primary coil induces eddy currents in the work-  piece, causing it to become heated. The depth to which the eddy currents  penetrate, and therefore the distribution of heat within the object, depend</p><p>on the frequency of the primary alternating current and the magnetic per�  meability, as well as the resistivity, of the material.</p><p>indulgence In Roman Catholicism, the remission of temporal punish�  ment for a sin after the sin has been forgiven through the sacrament of  penance. The theology of indulgences is based on the concept that, even  though the sin and its eternal punishment are forgiven through penance,  divine justice demands that the sinner pay for the crime either in this life  or in purgatory. The first indulgences were intended to shorten times of  penance by substituting periods of fasting, private prayers, almsgiving,  and monetary payments that were to be used for religious purposes. Pope  Urban II granted the first plenary, or absolute, indulgence to participants  in the First Crusade, and subsequent popes offered indulgences on the  occasion of the later Crusades. After the 12th century they were more  widely used, and abuses became common as indulgences were put up for  sale to earn money for the church or to enrich unscrupulous clerics. Jan  Hus opposed them, and Martin Luther�s Ninety-five Theses (1517) were in  part a protest against indulgences. In 1562 the Council of Trent put an end  to the abuses but not to the doctrine itself.</p><p>Indus civilization (c. 2500-c. 1700 bc) Earliest known urban culture  of the Indian subcontinent and the most extensive of the world�s three  earliest civilizations.

It is  known to have included two large cities, Harappa and Mohenjo Daro (in  what is now Pakistan), whose large size suggests centralization in two  large states or one state with two capitals. Alternatively, Harappa may  have succeeded Mohenjo Daro. It was a literate civilization; the language  has been tentatively identified as Dravidian. Wheat and barley were  grown, many animals (including cats, dogs, and cattle) were domesticated,  and cotton was cultivated. The best-known artifacts are seals depicting  real and imaginary animals.

After crossing into the Kashmir region, it continues northwest�  ward through the Indian- and Pakistani-administered areas and then turns  south into Pakistan. Swelled by tributaries from the Punjab region, includ�  ing the Jhelum, Chenab, Ravi, Beas, and Sutlej rivers, it widens and flows  more slowly. It has supplied water for irrigation on the plains of Pakistan  since early times.</p><p>industrial and organizational relations or organizational  relations Study of human behaviour in the workplace, focusing espe�  cially on the influence such relations have on an organization�s produc�  tivity. Classical economics viewed workers as instruments of production,  subject to the laws of supply and demand. Industrial relations did not  become the subject of scholarly attention until the late 1920s, when Elton  Mayo (1880-1949) studied productivity at Western Electric Co.�s Haw�  thorne Works. Concluding that merely being chosen to participate in the  study improved workers� productivity (the �Hawthorne effect�), Mayo  became the first scholar to show workers responding to psychosocial  stimuli. Other aspects of industrial and organizational relations include  human resources management, which involves the development of job  descriptions and organizational structures; recruiting, training, and gen�  eral oversight of employees; negotiating terms of employment, planning  for the future, and the study of managerial styles.</p><p>industrial design Design of products made by large-scale industry  for mass distribution. Among the considerations for such products are  structure, operation, appearance, and conformance to production, distri�  bution, and selling procedures; appearance is the principal consideration  in industrial design. The International Council of Societies of Industrial  Design was founded in London in 1957 and within 25 years had mem�  bers in more than 40 countries. Two significant trends have persisted:  streamlining, a design principle pioneered by Raymond Loewy and others  in the 1930s; and planned obsolescence, design changes that tempt own�  ers to replace goods with new purchases more frequently than would nor�  mally be necessary.</p><p>industrial ecology Discipline that traces the flow of energy and mate�  rials from their natural resources through manufacture, the use of prod�  ucts, and their final recycling or disposal. Research in industrial ecology  began in the early 1990s. Life-cycle analysis traces the flow of materials;  design for the environment works to minimize energy use, pollution, and  waste. Industrial ecologists aim to create industries in which every waste  is a raw material for another product.</p><p>industrial engineering Application of engineering principles and  techniques of scientific management to the maintenance of high levels of  productivity at optimum cost in industrial enterprises. Frederick W. Taylor  pioneered in the scientific measurement of work, and Frank (1868-1924)  and Lillian (1878-1972) Gilbreth refined it with time-and-motion studies.  As a result, production processes were simplified, enabling workers to  increase production. The industrial engineer selects tools and materials  for production that are most efficient and least costly to the company. The  engineer may also determine the sequence of production and the design  of plant facilities or factories. See also ergonomics.</p><p>industrial espionage Acquisition of trade secrets from business  competitors. Industrial spying is a reaction to the efforts of many busi�  nesses to keep secret their designs, formulas, manufacturing processes,  research, and future plans. Trade secrets may find their way into the open  market through disloyal employees or through various other means. Pen�  alties against those found guilty range from an injunction against further  use of the knowledge to substantial damages. See also patent.</p><p>industrial medicine or occupational medicine Branch of medi�  cine dealing with workers� health and the prevention and treatment of  diseases and injuries in the workplace. Workplace hazards include expo�  sure to dangerous materials including asbestos and coal dust, radiation  exposure, and machinery capable of causing injuries ranging from minor  to life-threatening. Industrial medical programs mandate protective  devices around machines� moving parts, proper ventilation of work areas,  use of less toxic materials, containment of production processes, and pro�  tective equipment and clothing. Good industrial medical programs  improve labour-management relations, increase workers� overall health  and productivity, and reduce insurance costs.</p><p>industrial melanism Vme-lo-.ni-zonA Darkness of the skin, feathers,  or fur developed by a population of animals living in an industrial region  where the environment is soot-darkened. The melanization of a popula�</p><p>tion increases the probability that its members will survive and reproduce  because it offers protection in the form of camouflage; it takes place over  the course of many generations as the result of natural selection of the  lighter, more conspicuous animals by predators.</p><p>industrial-organizational psychology or 1-0 psychology</p><p>Application of the concepts and methods of experimental, clinical, and social  psychology to the workplace. 1-0 psychologists are concerned with such  matters as personnel evaluation and placement, job analysis, worker-  management relations (including morale and job satisfaction), workforce  training and development (including leadership training), and productiv�  ity improvement. They may work closely with business managers, indus�  trial engineers, and human-resources professionals.</p><p>Industrial Revolution Process of change from an agrarian, handicraft  economy to one dominated by industry and machine manufacture. It  began in England in the 18th century. Technological changes included the  use of iron and steel, new energy sources, the invention of new machines  that increased production (including the steam engine and the spinning  jenny), the development of the factory system, and important develop�  ments in transportation and communication (including the railroad and  the telegraph). The Industrial Revolution was largely confined to Britain  from 1760 to 1830 and then spread to Belgium and France. Other nations  lagged behind, but, once Germany, the U.S., and Japan achieved indus�  trial power, they outstripped Britain�s initial successes. Eastern European  countries lagged into the 20th century, and not until the mid-20th century  did the Industrial Revolution spread to such countries as China and India.  Industrialization effected changes in economic, political, and social orga�  nization. These included a wider distribution of wealth and increased  international trade; political changes resulting from the shift in economic  power; sweeping social changes that included the rise of working-class  movements, the development of managerial hierarchies to oversee the  division of labour, and the emergence of new patterns of authority; and  struggles against externalities such as industrial pollution and urban  crowding.</p><p>Industrial Workers of the World (IWW) known as the Wob-  blies Radical labour organization founded in Chicago in 1905. The  founders, who opposed the moderate policies of the AFL (see AFL-CIO),  included William Haywood of the Western Federation of Miners, Daniel De  Leon of the Socialist Labor Party, and Eugene V. Debs. In 1908 the IWW  split, and a militant group led by Haywood prevailed. To reach its goal  of worker control of the means of production, it advocated general strikes,  boycotts, and sabotage. Its tactics led to arrests and adverse publicity,  though it made gains through strikes in the mining and lumber industries.  It opposed U.S. participation in World War I, and some of its leaders were  prosecuted. By the 1920s membership had dwindled greatly.</p><p>industrialization Process of converting to a socioeconomic order in  which industry is dominant. The changes that took place in Britain dur�  ing the Industrial Revolution of the late 18th and 19th century led the way  for the early industrializing nations of western Europe and North America.  Industrialization entailed both technology and profound social develop�  ments. The freeing of labourers from feudal and customary obligations  created a free market in labour, with a pivotal role for the entrepreneur.  Cities attracted large numbers of people, massing workers in new indus�  trial towns and factories. Later industrializers attempted to manipulate  some of the elements: the Soviet Union eliminated the entrepreneur; Japan  stimulated and sustained the entrepreneur�s role; Denmark and New  Zealand industrialized primarily by commercializing and mechanizing  agriculture.</p><p>industry Group of productive organizations that produce or supply  goods, services, or sources of income. In economics, industries are cus�  tomarily classified as primary, secondary, and tertiary; secondary industries  are further classified as heavy and light. Primary industry includes agricul�  ture, forestry, fishing, mining, quarrying, and extracting minerals. Second�  ary or manufacturing industry processes the raw materials supplied by  primary industries into consumer goods, or further processes goods from  other secondary industries, or builds capital goods used to manufacture  consumer and nonconsumer goods; secondary industry also includes  energy-producing industries and the construction industry. Tertiary or ser�  vice industry includes banking, finance, insurance, investment, and real  estate services; wholesale, retail, and resale trade; transportation, informa�  tion, and communications services; professional, consulting, legal, and  personal services; tourism, hotels, restaurants, and entertainment; repair</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>940 I Indy &#x25BA; inflation</p><p>and maintenance services; education and teaching; and health, social wel�  fare, administrative, police, security, and defense services.</p><p>Indy \a n -'de\, (Paul-Marie-Theodore-) Vincent d' (b. March 27,  1851, Paris, France�d. Dec. 1, 1931, Paris) French composer and teacher.  Trained in organ and composition, he rejected the prevailing French style  as frivolous by comparison with the German musical tradition. He wrote  several important stage works, including Fervaal (1895) and The Legend  of Saint Christopher (1915), but orchestral works such as Symphony on  a French Mountain Air (1886), Summer Day in the Mountains (1905),  and Istar (1896) remain better known. In 1894 he cofounded the music  academy called the Schola Cantorum in Paris, where many of France�s  foremost composers and musicians would be trained.</p><p>inequality In mathematics, a statement of an order relationship�  greater than, greater than or equal to, less than, or less than or equal  to�between two numbers or algebraic expressions. Inequalities can be  posed either as questions, much like equations, and solved by similar  techniques, or as statements of fact in the form of theorems. For example,  the triangle inequality states that the sum of the lengths of any two sides  of a triangle is greater than or equal to the length of the remaining side.  Mathematical analysis relies on many such inequalities (e.g., the Cauchy-  Schwarz inequality) in the proofs of its most important theorems.</p><p>inert gas See noble gas</p><p>inertia U-'nor-shoV Inherent property of a body that makes it oppose any  force that would cause a change in its motion. A body at rest and a body  in motion both oppose forces that might cause acceleration. The inertia  of a body can be measured by its mass, which governs its resistance to  the action of a force, or by its moment of inertia about a specified axis,  which measures its resistance to the action of a torque about the same  axis.</p><p>inertia, moment of Quantitative measure of the rotational inertia of  a body. As a rotating body spins about an external or internal axis (either  fixed or unfixed), it opposes any change in the body�s speed of rotation  that may be caused by a torque. It is defined as the sum of the products  obtained by multiplying the mass of each particle of matter in a given  body by the square of its distance from the axis of rotation.</p><p>inertial guidance system An electronic system that continuously  monitors the position, velocity, and acceleration of a vehicle, usually a  submarine, missile, or airplane, and thus provides navigational data or  control. The basic components of an inertial guidance system are gyro�  scopes, accelerometers, and a computer.</p><p>infancy In humans, the period of life between birth and the acquisition  of language usually one to two years later. The average newborn infant  weighs 7.5 lbs (3.4 kg) and is about 20 in (51 cm) long. At birth, infants  display a set of inherited reflexes involving such acts as sucking, blink�  ing, and grasping. They are sensitive to light-dark visual contrasts and  movements and show a noticeable preference for gazing at the human  face; they also begin to recognize the human voice. By 4 months of age  most babies are able to sit up, and most begin crawling in 7-10 months;  by 12 months most are able to start walking. Virtually all infants begin  to comprehend some words several months before they themselves speak  their first meaningful words.</p><p>infanticide Killing of the newborn. Infanticide has often been inter�  preted as a primitive method of birth control and a means of ridding a  group of its weak or undesirable children; but most societies actively wel�  come children and put them to death (or allow them to die) only under  exceptional circumstances�e.g., when there is little or no likelihood of  being able to provide support. As late as the 18th century in European  countries unwanted infants were disposed of by abandonment and expo�  sure. Firstborn sacrifice, or the offering of one�s most precious possession  to the deities, is known from the Bible and from the histories of Egypt,  Greece, Rome, and India.</p><p>infantile paralysis See poliomyelitis</p><p>infantry Troops who fight on foot. The term applies both to soldiers  armed with hand weapons such as the spear and sword in ancient times  and to troops armed with automatic rifles and rocket launchers in mod�  ern times. Their objective has always been to seize and hold ground and,  when necessary, to occupy enemy territory. Apart from the temporary  dominance of cavalry in the feudal period, it has been the largest single  element in Western armies since ancient times.</p><p>infection Invasion of the body by various agents�including bacteria,  fungi (see fungus), protozoans, viruses, and worms �and its reaction to  them or their toxins. Infections are called subclinical until they percepti�  bly affect health, when they become infectious diseases. Infection can be  local (e.g., an abscess), confined to one body system (e.g., pneumonia in  the lungs), or generalized (e.g., septicemia). Infectious agents can enter the  body by inhalation, ingestion, sexual transmission, passage to a fetus dur�  ing pregnancy or birth, wound contamination, or animal or insect bites.  The body responds with an attack on the invader by leukocytes, produc�  tion of antibodies or antitoxins, and often a rise in temperature. The anti�  bodies may result in short-term or lifelong immunity. Despite significant  progress in preventing and treating infectious diseases, they remain a  major cause of illness and death, particularly in regions of poor sanita�  tion, poor nutrition, and crowding.</p><p>inferiority complex Acute sense of personal inferiority, often result�  ing in either timidity or (through overcompensation) exaggerated aggres�  siveness. Though once a standard psychological concept, particularly  among followers of Alfred Adler, it has lost much of its usefulness through  imprecise popular misuse.</p><p>infertility Inability of a couple to conceive and reproduce. It is defined  as failure to conceive after one year of regular intercourse without con�  traception. Inability to conceive when desired can result from a defect at  any of the stages required for fertility (see reproductive system). About one  in every eight couples is infertile. Most cases involve the female partner,  30^40% involve the male, and 10% are caused by unknown factors. In  women, causes include ovulation or hormone problems, fallopian-tube  disorders, and a chemical balance that is hostile to sperm; in men, causes  include impotence, low sperm count, and sperm abnormalities. Either part�  ner can have a blockage of the pathways the sperm must travel, often  treatable by surgery. Emotional factors may contribute; return of normal  fertility may require only counseling. Fertility drugs can stimulate the  release of eggs (often more than one, leading to multiple births). Low sperm  count may be overcome by limiting intercourse to the time of ovulation,  the most fertile period. If these methods are unsuccessful, couples may  try ARTIFICIAL insemination, in vitro fertilization, or SURROGATE motherhood, or  they may choose adoption instead.</p><p>infinite series In mathematics, the sum of infinitely many numbers,  whose relationship can typically be expressed as a formula or a function.  An infinite series that results in a finite sum is said to converge (see con�  vergence). One that does not, diverges. Mathematical analysis is largely  taken up with studying the conditions under which a given function will  result in a convergent infinite series. Such series (e.g., the Fourier series)  are particularly useful in solving differential equations.</p><p>infinity In mathematics, the useful concept of a process with no end. As  represented by the symbol �&gt;, it is often mistakenly thought to be the largest  number or a place on the real number line. Instead, it is the idea of a limit,  as in the expression x �&gt; ��, which suggests that the variable x increases  without bound. For example, the function/(x) = l/x, or the reciprocal of x,  tends toward 0 as x approaches infinity as a limit. This process of approach�  ing is crucial to the definition of the derivative and the integral in calculus,  as well as to many other concepts of mathematical analysis.</p><p>inflammation Local reaction of living tissues to injury or illness,  including burns, pneumonia, leprosy, tuberculosis, and rheumatoid arthri�  tis. Its major signs are heat, redness, swelling, and pain. The process  begins with brief contraction of nearby arterioles (see arteries). Dilation  follows, flushing the capillaries with blood, from which fluid, plasma pro�  teins, and leukocytes pass into the injured tissues, causing swelling as they  attack the cause of injury. Initial acute inflammation can have any of four  outcomes: resolution (return to normal), organization (new tissue buildup;  see scar), suppuration (pus formation; see abscess), or chronic inflamma�  tion. Sometimes treatment�including antibiotics for bacteria, or surgical  removal of an irritating foreign body�can eliminate the cause. If not,  anti-inflammatory drugs (e.g., cortisone or aspirin) may be given, or simple  remedies (e.g., hot or cold compresses) may be applied.</p><p>inflation In cosmology, a hypothesized period of exponential expansion  of the universe, shortly after the big bang, which may account for some  of the universe�s observed properties, such as the distribution of energy  and matter. Grand unified theories of the forces of nature suggest that infla�  tion could have occurred during the first 10 -32 second after the universe  began, when the strong force was decoupling from the weak and electro�  magnetic forces. During this time, the universe would have expanded by</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>inflation &#x25BA; Ingres I 941</p><p>more than 100 orders of magnitude. Interpreted in the context of general  relativity, inflation occurred while the universe existed in a state of non�  zero energy density (false vacuum).</p><p>inflation In economics, increases in the level of prices. Inflation is gen�  erally thought of as an inordinate rise in the general level of prices. Four  theories are commonly used to explain inflation. The first and oldest, the  quantity theory, promoted in the 18th century by David Hume, assumes that  prices will rise as the supply of money increases. Milton Friedman refined  the quantity theory in the mid-20th century, arguing that the prescription  for stable prices is to increase the money supply at a rate equal to that at  which the economy is expanding. A second approach is John Maynard  Keynes�s theory of income determination, which assumes that inflation  occurs when the demand for goods and services is greater than the sup�  ply. It calls for the government to control inflation by adjusting levels of  spending and taxation and by raising or lowering interest rates. A third  approach is the cost-push theory. It traces inflation to a phenomenon  known as the price-wage spiral, in which workers� demands for wage  increases lead employers to increase prices to reflect their higher costs,  thereby sowing the seeds of a further round of wage demands. A fourth  approach is the structural theory, which emphasizes structural maladjust�  ments in the economy, as when in developing countries imports tend to  increase faster than exports, pushing down the international value of the  developing country�s currency and causing prices to rise internally. See  also DEFLATION, PRICE INDEX.</p><p>inflorescence \,in-fl9-'re-s 3 ns\ Cluster of flowers on one or a series of  branches, which together make a large showy blossom. Categories depend  on the arrangement of flowers on an elongated main axis (peduncle) or  on sub-branches from the main axis, and on the timing and position of  flowering. In determinate inflorescences, the youngest flowers are at the  bottom or outside (e.g., onion flowers). In indeterminate inflorescences,  the youngest flowers are at the top or in the center (e.g., snapdragon, lily  of the valley, and Astilbe flowers). Other indeterminate inflorescences are  the dangling male and female catkins of oak trees, the spike of barley, and  the flat head (capitulum) of the dandelion.</p><p>influenza or flu or grippe Acute viral infection of the upper or lower  respiratory tract. Influenza viRUSes A (the most common), B, and C pro�  duce similar symptoms, but infection with or vaccination against one does  not give immunity against the others. Chills, fatigue, and muscle aches  begin abruptly. The temperature soon reaches 38-40 �C (101-104 �F).  Head, muscle, abdominal, and joint aches may be accompanied by sore  throat. Recovery starts in three to four days, and respiratory symptoms  become more prominent. Bed rest, high fluid intake, and aspirin or other  antifever drugs are standard treatment. Influenza A tends to occur in wave�  like annual pandemics. Mortality is usually low, but in rare outbreaks (see  influenza epidemic of 1918-19) it reaches immense proportions. Most  deaths result from pneumonia or bronchitis.</p><p>influenza epidemic of 1918-19 or Spanish influenza epi�  demic Most severe influenza outbreak of the 20th century. It apparently  started as a fairly mild strain in a U.S. army camp in early March 1918.  Troops sent to fight in World War I spread the virus to western Europe.  Outbreaks occurred in nearly every inhabited part of the world, spread�  ing from ports to cities along transportation routes. Pneumonia often devel�  oped quickly and killed within two days. Among the most deadly  epidemics in history, it left an estimated 25 million dead; unusually, half  the deaths were among 20- to 40-year-olds.</p><p>information processing Acquisition, recording, organization,  retrieval, display, and dissemination of information. Today the term usu�  ally refers to computer-based operations. Information processing consists  of locating and capturing information, using software to manipulate it into  a desired form, and outputting the data. An Internet search engine is an  example of an information-processing tool, as is any sophisticated  INFORMATION-RETRIEVAL system. See also DATA PROCESSING.</p><p>information retrieval Recovery of information, especially in a data�  base stored in a computer. Two main approaches are matching words in  the query against the database index (keyword searching) and traversing  the database using hypertext or hypermedia links. Keyword searching has  been the dominant approach to text retrieval since the early 1960s; hyper�  text has so far been confined largely to personal or corporate information-  retrieval applications. Evolving information-retrieval techniques,  exemplified by developments with modern Internet search engines, com�  bine natural language, hyperlinks, and keyword searching. Other tech�</p><p>niques that seek higher levels of retrieval precision are studied by  researchers involved with artificial intelligence.</p><p>information science Discipline that deals with the processes of stor�  ing and transferring information. It attempts to bring together concepts  and methods from such varied disciplines as library science, computer  science and engineering, linguistics, and psychology to develop tech�  niques and devices to aid in the handling of information. In its early stages  in the 1960s, information science was concerned primarily with applying  the then-new computer technology to the processing and managing of  documents. The applied computer technologies and theoretical studies of  information science have since permeated many other disciplines. Com�  puter science and engineering still tend to absorb its theory- and  technology-oriented subjects, and management science tends to absorb  information-systems subjects.</p><p>information theory See communication theory</p><p>infrared V.in-fro-'redX astronomy Study of astronomical objects by  observing the infrared radiation they emit. Its techniques enable examina�  tion of many celestial objects that give off energy at wavelengths in the  infrared region of the electromagnetic spectrum but that cannot otherwise be  seen from Earth because they do not emit much visible light or because  that light is blocked by dust clouds, which infrared radiation can penetrate.  Infrared astronomy originated in the early 19th century with the work of  William Herschel (see Herschel family), who discovered infrared radiation  while studying sunlight. The first systematic infrared observations of other  stars were made in the 1920s; modem techniques, such as the use of inter�  ference filters for ground-based telescopes, were introduced in the early  1960s. Because atmospheric water vapour absorbs many infrared wave�  lengths, observations are carried out with telescopes sited on high moun-  taintops and from airborne and space-based observatories. Infrared  astronomy allows studies of the dust-obscured core of the Milky Way Gal�  axy and the hearts of star-forming regions and has led to many discoveries  including brown dwarf candidates and disks of matter around certain stars.</p><p>infrared radiation Portion of the electromagnetic spectrum that extends  from the microwave range to the red end of the visible light range. Its wave�  lengths vary from about 0.7 to 1,000 micrometres. Most of the radiation  emitted by a moderately heated surface is infrared, and it forms a continu�  ous spectrum. Molecular excitation produces extensive infrared radiation  but in a discrete spectrum of lines or bands. Infrared wavelengths are useful  for night-vision equipment, heat-seeking missiles, molecular spectroscopy,  and infrared astronomy, among other things. The trapping of infrared radia�  tion by atmospheric gases is also the basis of the greenhouse effect.</p><p>Inge \'inj\, William (Motter) (b. May 3, 1913, Independence, Kan.,  U.S.�d.

His first play. Far�  ther Off from Heaven (1947), was revised for Broadway as The Dark at  the Top of the Stairs (1957; film, 1960). He is best known for his plays  Come Back, Little Sheba (1950; film, 1952), Picnic (1953, Pulitzer Prize;  film, 1956), and Bus Stop (1955; film, 1956), and for his original screen�  play for Splendor in the Grass (1961, Academy Award).

He studied  with Jacques- Louis David in Paris before attending the Ecole des Beaux-  Arts (1799-1801), where he won a Prix de Rome scholarship. Critics  condemned one of his first public works, the awe-inspiring portrait Napo�  leon on His Imperial Throne (1806), as stiff and archaic, but its style was  one he developed intentionally. In Italy (1806-24) he prospered with por�  traits and history paintings. His small-scale portrait drawings are meticu-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>942 I inheritance &#x25BA; Innes</p><p>lously rendered. Back in Paris he  received critical acclaim at last and  won admission to the academy with  The Vow of Louis XIII (1824). He  succeeded David as the leader of  French Neoclassical painting, a style  that was the antithesis of the lush  Romanticism of contemporary artists  such as Eugene Delacroix, Ingres�s  chief rival. In 1825 he opened a  teaching studio, which became one  of the largest in Paris. By the mid  1840s he was France�s most sought-  after society portraitist. Some of his  most notable later works are female  nudes, which are often notable for  their elongated distortion. None of  his many students attained distinc�  tion, but his influence is seen in the  work of Edgar Degas, Pierre-Auguste  Renoir, and Pablo Picasso.</p><p>inheritance Devolution of prop�  erty on an heir or heirs upon the  death of its owner. In civil law juris�  dictions it is called succession. The  concept depends on a common acceptance of the notion of private own�  ership of goods and property. Under some systems, land is considered  communal property and rights to it are redistributed, rather than  bequeathed, on the death of a community member. In many countries, a  minimum portion of the decedent�s estate must be assigned to the sur�  viving spouse and often to the progeny as well. Intestacy laws, which  govern the inheritance of estates whose distribution is not directed by a  will, universally view kinship between the decedent and the beneficiary  as a primary consideration. Inheritance usually entails payment of an  inheritance tax. See also inheritance tax; intestate succession; probate.</p><p>inheritance tax Levy on the property accruing to each beneficiary of  the estate of a deceased person. Inheritance tax may be more difficult to  administer than estate tax because the value passing to each beneficiary  must be fixed, and this often requires complex actuarial calculations.  Inheritance taxes date back to the Roman Empire. In the U.S. inheritance  taxes have always been collected by the individual states, while the fed�  eral government has imposed an estate tax. The first state inheritance tax  was imposed by Pennsylvania in 1826.</p><p>inhibition In enzymology, a phenomenon in which a compound (an  inhibitor), usually similar in structure to the substance on which an enzyme  acts (substrate), interacts with the enzyme so that the resulting complex  cannot undergo the usual reaction or cannot form the usual product. The  inhibitor may function by combining with the enzyme at the site at which  the reaction usually occurs (competitive inhibition) or at another site (non�  competitive inhibition). See also allosteric control, feedback inhibition,</p><p>REPRESSION.</p><p>inhibition In psychology, the conscious or unconscious suppression of  free or spontaneous thought or behaviour through the operation of psycho�  logical impediments, including internalized social controls. Inhibition  serves useful social functions such as protecting oneself and others from  harm and enabling the delay of gratification from pleasurable activities.  Both extreme lack of inhibition and excessive inhibition can be personally  destructive. Inhibition also plays an important role in learning, since an  organism must learn to restrain certain instinctual behaviours or previously  learned patterns in order to master new patterns. In physiological psychol�  ogy, inhibition refers to the suppression of neural electrical activity.</p><p>initiation See rite of passage, secret society</p><p>injunction In civil proceedings, a court order compelling a party to do  or to refrain from doing a specified act. It is an equitable remedy for harm  for which no adequate remedy exists in law. Thus it is used to prevent a  future harmful action (e.g., disclosing confidential information, institut�  ing a national labour strike, or violating a group�s civil rights) rather than  to compensate for an injury that has already occurred. It also provides  relief from harm for which an award of money damages is not a satisfac�  tory solution. A defendant who violates an injunction may be cited for  contempt.

Modern writing  inks usually contain ferrous sulfate (see iron) with a small amount of an  acid; on paper, they darken and bond, becoming permanent. Coloured and  washable inks usually contain soluble synthetic dyes.

It originated in 1924 as a cultural move�  ment under King Dinizulu. His grandson, Mangosuthu G. Buthelezi,  revived it in 1974 as a political party after breaking with the African  National Congress (ANC). Under Buthelezi, Inkatha advocated a struggle  against apartheid but a willingness to accept power-sharing arrangements  short of majority rule. From the late 1980s Inkatha and ANC followers  were regularly involved in bloody clashes with strong ethnic (Zulu v.  non-Zulu) overtones. In 1991 the white South African government admit�  ted that it had secretly subsidized Inkatha.</p><p>Inland Passage See Inside Passage</p><p>Inn River Major tributary of the Danube River. It rises in Switzerland and  flows 317 mi (510 km) northeast across western Austria and southern  Germany. Its Swiss section is called the Engadin. In Austria it travels past  Innsbruck and along the Bavarian Alps, entering Germany in Bavaria,  where it flows northeast. It forms part of the Austro-German border as it  joins the Danube at Passau.</p><p>inner ear or labyrinth of the ear Part of the ear containing organs  of hearing and equilibrium. The bony labyrinth has three sections (semi�  circular canals, vestibule, and cochlea); within each structure is a corre�  sponding part of the membranous labyrinth (semicircular ducts, two  saclike structures in the vestibule, and cochlear duct). Sound vibrations  are transmitted from the middle ear through the membrane-covered oval  window to fluid in the snail-shell-shaped cochlea, whose motion stimu�  lates hair cells in the cochlea. The hair cells trigger nerve impulses that  travel to the brain, which interprets them as sound. The vestibule and  semicircular canals also have organs with hair cells. Those in the vesti�  bule indicate the head�s position with respect to the rest of the body (see  proprioception). The three semicircular canals, at right angles to each other,  signal motion of the head in three-dimensional space. Continued stimu�  lation after motion stops causes a mismatch with visual input, experienced  as dizziness or motion sickness.</p><p>Inner Mongolia Chinese Nei Mongol Vna-'muq-'goB or Nei-  meng-ku Vna-'moq-'gtA Autonomous region (pop., 2002 est.:  23,790,000), China. Stretching some 1,800 mi (2,900 km) across north-  northeastern China, it has an area of 454,600 sq mi (1,177,500 sq km);  its capital is Hohhot. Mongols and Chinese make up the bulk of the popu�  lation, most of which is concentrated in the agricultural belt near the  Huang He (Yellow River). Inner Mongolia is an inland plateau lying at  an elevation of about 3,300 ft (1,000 m); it is fringed by mountains and  valleys. Its northern portion lies within the Gobi Desert, and its southern  border is partly marked by the Great Wall. Inner Mongolia was separated  from Mongolia (Outer Mongolia) in 1912 and was established as an  autonomous region in 1947. Its harsh climate restricts intensive agricul�  ture; some industrial development has occurred there.</p><p>inner product space In mathematics, a vector space or function space  in which an operation for combining two vectors or functions (whose  result is called an inner product) is defined and has certain properties. Such  spaces, an essential tool of functional analysis and vector theory, allow  analysis of classes of functions rather than individual functions. In math�  ematical analysis, an inner product space of particular importance is a Hil�  bert space, a generalization of ordinary space to an infinite number of  dimensions. A point in a Hilbert space can be represented as an infinite  sequence of coordinates or as a vector with infinitely many components.  The inner product of two such vectors is the sum of the products of cor�  responding coordinates. When such an inner product is zero, the vectors  are said to be orthogonal (see orthogonality). Hilbert spaces are an essen�  tial tool of mathematical physics. See also David Hilbert.</p><p>Innes, Michael See J.I.M.

His early paintings were influenced by the Hudson  River school. He spent much time in Europe studying the works of the  Barbizon school, and from c. 1855 to 1874 he developed the luminous,  atmospheric quality for which his landscapes are known. The influence  of Camille Corot is evident in his intimately rendered images of far-  reaching expanses. His later works are marked by the ascendancy of  colour over form. His sense of mysticism intensified over time, and the  pictures tended to dissolve into shimmering colour with no outlines or  formal construction.

July 16, 1216, Perugia) Pope (1198-  1216). Innocent, who was trained in both theology and law, brought the  medieval papacy to the height of its prestige and power. He crowned Otto  IV as Holy Roman emperor, but Otto�s determination to unite Germany  and Sicily angered him, and in 1212 he gave his support to the Hohen-  staufen candidate, Frederick II. After Innocent excommunicated King John  of England for refusing to recognize Stephen Langton as archbishop of  Canterbury, John was obliged to submit and to declare England a fief of  the Holy See (1213). Innocent launched the Fourth Crusade, which cap�  tured Constantinople, and the Albigensian Crusade, which attempted to  suppress heresy in southern France. He approved the Mendicant orders  founded by St. Dominic and St. Francis of Assisi, and he convoked the  fourth Lateran Council, which promulgated the doctrine of transubstantia-  tion and endorsed annual confession for all Christians.</p><p>Innocent IV orig. Sinibaldo Fieschi (b. 12th century, Genoa�d.  Dec. 7, 1254, Naples) Pope (1243-54). His clash with Holy Roman  Emperor Frederick II formed an important chapter in the conflict between  papacy and empire. Frederick wanted the newly elected pope to lift his  excommunication, but Innocent interrupted the negotiations and fled  Rome for France (1244); he later condemned Frederick and urged the  election of a new emperor. Concerned with the evangelization of the East,  he persuaded Louis IX to lead a Crusade and sent a mission to the Mon�  gols. He returned to Rome in 1253 and gave the Sicilian throne to  Edmund, son of Henry III of England, but the papal army was defeated by  Manfred, Frederick�s son, in 1254.</p><p>innovation In technology, an improvement to something already exist�  ing. Distinguishing an element of novelty in an invention remains a con�  cern of patent law. The Renaissance was a period of unusual innovation:  Leonardo da Vinci produced ingenious designs for submarines, airplanes,  and helicopters and drawings of elaborate trains of gears and of the pat�  terns of flow in liquids. Technology provided science with instruments  that greatly enhanced its powers, such as Galileo�s telescope. New sci�  ences have also contributed to technology, as in the theoretical prepara�  tion for the invention of the steam engine. In the 20th century, innovations  in semiconductor technology increased the performance and decreased the  cost of electronic materials and devices by a factor of a million, an  achievement unparalleled in the history of any technology.</p><p>Inns of Court Four societies of British students and practitioners of  law that have the exclusive right to admit people to practice. The four are  Lincoln�s Inn, Gray�s Inn, Inner Temple, and Middle Temple. All are  located in London and trace their origins to the Middle Ages. Until the  17 th century, when the Inn of Chancery developed (for training in the  framing of writs and other legal documents used in the courts of chan�  cery, or equity courts), the Inns of Court had a monopoly over legal edu�  cation. By the 19th century, modem law schools had emerged.</p><p>Innsbruck City (pop., 2001: 113,392), on the Inn River in western Aus�  tria, southwest of Salzburg. A small market town in the 12th century, it  was located beside a bridge ( Briicke) over the Inn. It was chartered in  1239, passed to the Habsburgs in 1363, and in 1420 became the capital of  Tirol. Napoleon gave the city to Bavaria in 1806, and in 1809 it was the  site of an uprising of Tirolian patriots against the Bavarians and the  French. The old town has narrow streets lined with medieval houses and  arcades. A winter sports centre, Innsbruck was the site of the Winter  Olympic Games in 1964 and 1976.</p><p>Inonu \i-nce-'mE\ A Ismet (b. Sept. 24, 1884, Smyrna, Ottoman  Empire�d.

He became prime minister in 1923, and presi�  dent and permanent chairman of the Republican People�s Party in 1938  on Mustafa Kemal AtatOrk�s death. In 1950 he was replaced as president  by Celal Bayar and led the opposition, assuming the role of defender of  democracy. Following a 1960 coup d�etat, he formed three coalition gov�  ernments, but in the 1965 and 1969 elections his party suffered over�  whelming defeats.</p><p>inorganic compound Any substance in which two or more chemi�  cal elements other than carbon are combined, nearly always in definite  proportions (see bonding), as well as some compounds containing carbon  but lacking carbon-carbon bonds (e.g., carbonates, cyanides). Inorganic  compounds may be classified by the elements or groups they contain (e.g.,  oxides, sulfates). The major classes of inorganic polymers are silicones,  silanes, silicates, and borates. Coordination compounds (or complexes),  an important subclass of inorganic compounds, consist of molecules with  a central metal atom (usually a transition element) bonded to one or more  nonmetallic ligands (inorganic, organic, or both) and are often intensely  coloured. See also organic compound.</p><p>inosilicate Un-o-'si-b-kot, .I-no-'si-ta-koA or chain silicate Any of  a class of inorganic compounds that have structures characterized by sili�  cate tetrahedrons (a central silicon atom surrounded by four oxygen atoms  at the corners of a tetrahedron) arranged in chains. Two of the oxygen  atoms of each tetrahedron are shared with other tetrahedrons, forming a  chain that is potentially infinite in length. Mineral examples include the  pyroxenes and the amphiboles.</p><p>Inoue Enryd Ve-'no-ii-e-'en-'ryoX (b. March 18, 1858, Echigo province,  Japan�d.

He opposed the  Westernization of Japan and the conversion of officials to Christianity. He  founded the Philosophical Institute in 1887 to promote the study of Bud�  dhism. As part of his campaign to rid Japan of superstitions associated with  folklore and mythology, he established the Ghost Lore Institute in Tokyo.</p><p>input-output analysis Economic analysis developed by Wassily  Leontief, in which the interdependence of an economy�s various productive  sectors is observed by viewing the product of each industry both as a com�  modity for consumption and as a factor in the production of itself and other  goods. For example, input-output analysis will break down a nation�s total  production of trucks, showing that some trucks are used in the production  of more trucks, some in farming, some in the production of houses, and so  on. An input-output analysis is usually summarized in a gridlike table  showing what various industries buy from and sell to one another.</p><p>Inquisition In the Middle Ages, a judicial procedure that was used to  combat heresy; in early modern times, a formal Roman Catholic judicial  institution. Inquisito, a Latin term meaning investigation or inquest, was  a legal procedure that involved the assemblage of evidence and the pros�  ecution of a criminal trial. Use of the procedure against the heresies of  the Cathari and Waldenses was approved by Pope Gregory IX in 1231.  Suspected heretics were arrested, interrogated, and tried; the use of tor�  ture was approved by Innocent IV in 1252. Penalties ranged from prayer  and fasting to imprisonment; convicted heretics who refused to recant  could be executed by lay authorities. Medieval inquisitors functioned  widely in northern Italy and southern France. The Spanish Inquisition was  authorized by Sixtus IV in 1478; the pope later tried to limit its powers but  was opposed by the Spanish crown. The auto-da-fe, the public ceremony  at which sentences were pronounced, was an elaborate celebration, and  the grand inquisitor Tomas de Torquemada was responsible for burning  about 2,000 heretics at the stake. The Spanish Inquisition was also intro�  duced into Mexico, Peru, Sicily (1517), and the Netherlands (1522), and  it was not entirely suppressed in Spain until the early 19th century.</p><p>insanity In criminal law, a disease, defect, or condition of the mind that  renders one unable to understand the nature of a criminal act or the fact that  it is wrong. Tests of insanity are not intended as medical diagnoses but  rather only as determinations of whether a person may be held criminally  responsible for his or her actions. The most enduring definition of insanity  in Anglo-American law was that proposed by Alexander Cockburn (1843).  Many U.S. states and several courts have adopted a standard under which  the accused must lack �substantial capacity either to appreciate the crimi�  nality of his conduct or to conform his conduct to the requirements of the  law.� Some states have abolished the insanity plea, and others allow a find�  ing of �guilty but mentally ill.� See also diminished responsibility.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>944 I insect &#x25BA; Institutional Revolutionary Party</p><p>insect Any member of the class Insecta, the largest arthropod class,  including nearly 1 million known species (about three-fourths of all ani�  mals) and an estimated 5-10 million undescribed species. Insect bodies  have three segments: head, thorax (which bears three pairs of legs and usu�  ally two pairs of wings), and many-segmented abdomen. Many species  undergo complete metamorphosis. There are two subclasses: Apterygota  (primitive, wingless forms, including silverfish and bristletails) and Ptery-  gota (more advanced, winged or secondarily wingless forms). The approxi�  mately 27 orders of Pterygota are generally classified by wing form: e.g.,  Coleoptera (beetles), Diptera (dipterans), Heteroptera (bugs). Insects are  found in almost all terrestrial and freshwater and some marine habitats.</p></section><section><p>Body plan of a generalized insect. The body is usually divided into a head, thorax,  and abdomen. The head bears appendages modified into mouthparts and anten�  nae bearing sense organs. Mouthparts include the toothed mandibles and bladelike  maxillae found behind the "upper lip," or labrum. A second pair of maxillae, partly  fused, form the "lower lip," or labium. An adult usually has both simple eyes (ocelli)  and more-complex faceted compound eyes, as well as a pair of wings on the tho�  rax. The tarsal segment of the jointed leg often has claws with adhesive pads,  enabling the insect to hold onto smooth surfaces. In some insects (including crickets  and cockroaches), a pair of feelers (cerci) bearing sense organs are located at the  rear of the abdomen. Tiny openings (spiracles) on the thorax and abdomen allow  passage of oxygen to and release of carbon dioxide from internal air-filled tubules  or tracheae. Sperm from the male is stored in the female's spermatheca until an  egg released from the ovary passes through the oviduct. The female may have an  ovipositor for depositing eggs.</p><p>� MERRIAM-WEBSTER INC.</p><p>insecticide Any of a large group of substances used to kill insects. Such  substances are mainly used to control pests that infest cultivated plants  and crops or to eliminate disease-carrying insects in specific areas. Inor�  ganic insecticides include arsenic, lead, and copper compounds. Some  organic insecticides are natural, such as rotenone, pyrethrins, and nicotine  (see toxin). Others are synthetic, such as chlorinated hydrocarbons (e.g.,  DDT, dieldrin, lindane); carbamates, related to urea (e.g., carbaryl, carbo-  furan); and parathions, organic phosphorus esters. Insect hormones may be  included as a class. Insecticides may affect the nervous system, inhibit  essential enzymes, or prevent larvae from maturing (e.g., juvenile hor�  mone). Some are stomach poisons, some inhalation poisons, and others  contact poisons. Agents such as inert oils act mechanically, simply block�  ing the breathing pores. Insecticides vary widely not only in effectiveness  against target insects (which may develop resistance) but also in toxicity  to nontarget species (including humans) and environmental effects; many  of the worst (e.g., DDT) have been banned or their use curtailed.</p><p>insectivore Un-'sek-to-.voA Any member of the mammalian order  (Insectivora) that includes the hedgehogs, moles, and sometimes shrews  (some of which are considered primates by some authorities), or, more  generally, any animal that eats mainly insects. The mammalian insecti-  vores are generally small, active, and nocturnal. They are found in most  parts of the world except Antarctica, Australia, and South America. Most  species are solitary (except during the breeding season) and short-lived.</p><p>insei Japanese "cloistered government" Rule by retired emper�  ors who have taken Buddhist vows and retired to cloisters. During the  late 11th and the 12th century, governmental control of Japan passed from  the Fujiwara family, which had maintained power through marriages to the  imperial family, to cloistered emperors. By abdicating, these emperors  escaped the control of Fujiwara regents and chancellors; once inside a  temple or monastary, they surrounded themselves with capable non-  Fujiwara aristocrats. It was the edicts of the cloistered emperor, not the</p><p>reigning one, that were obeyed, insofar as any orders were obeyed in a  period of increasing collapse of central authority. The practice came to an  end with the reign of the emperor Go-Daigo (1318-39).

In the context of equity, insolvency is the inability to pay debts as  they become due; insolvency under the balance-sheet approach means that  total liabilities exceed total assets.</p><p>insomnia Inability to sleep adequately. The causes may include poor  sleeping conditions, circulatory or brain disorders, breathing disorders  (e.g., sleep apnea), mental distress (e.g., tension or depression), or physi�  cal discomfort. Mild insomnia may be treated by improving sleeping con�  ditions or through traditional remedies such as warm baths, milk, or  systematic relaxation. Apnea and its associated insomnia may be treated  surgically or mechanically with breathing apparatus. Severe or chronic  insomnia may necessitate the temporary use of barbiturates or tranquil�  izers, but such drugs are often addictive and may be decreasingly effec�  tive as the body builds up tolerance. Other methods of treatment include  PSYCHOTHERAPY and HYPNOSIS.</p><p>instinct Involuntary response by an animal, resulting in a predictable  and relatively fixed behaviour pattern. Instinctive behaviour is an inher�  ited mechanism that serves to promote the survival of an animal or spe�  cies. It is most apparent in fighting and sexual activity. The simplest form  is the reflex. All animals have instinct, but, in general, the higher the ani�  mal form, the more flexible the behaviour. Among mammals, learned  behaviour often prevails over instinctive behaviour.</p><p>Institut Canadien \a n -ste-'tiE-ka-nad- , ya n \ Literary and scientific soci�  ety that came into conflict with the Catholic Church in 19th-century  French Canada.

It criticized the institutionalism of the church in Quebec and dis�  played books considered undesirable. Church leaders, including Ignace  Bourget, bishop of Montreal (1840-76), attacked the institute, which  appealed to Rome for support. In 1869 the church condemned the move�  ment, and most members withdrew.</p><p>institutional economics School of economics that flourished in the  U.S. in the 1920s and �30s, which viewed the evolution of economic insti�  tutions as part of the broader process of cultural development. Thorstein  Veblen laid the foundation for institutionalism with his criticism of tradi�  tional economic theory. He tried to replace the concept of people as the  makers of economic decisions with a more realistic image of people as  influenced by changing customs and institutions. John R.

Dewey favored these terms over the term pragmatism to label  the philosophy on which his views of education rested. His school claimed  that cognition has evolved not for speculative or metaphysical purposes  but for the practical purpose of successful adjustment. Ideas are conceived  as instruments for transforming the uneasiness arising from facing a prob�  lem into the satisfaction of solving it.</p><p>instrumentation In technology, the development and use of precise  measuring, analysis, and control equipment. Among the oldest known  instruments of measurement was the armillary sphere, an astronomical  instrument used in ancient China and Greece. The compass was a striking  advance in navigational instrumentation made about the 11th century.  Theodolites made accurate determination of locations possible in the 18th  century. Instrumentation developed rapidly in the Industrial Revolution.  Manufacturing required precision instruments, such as the screw microme�  ter, which could measure 0.0001 in. (0.0025 mm). The industrial appli�  cation of electricity required instruments to measure current, voltage, and  resistance. Today most manufacturing processes rely on instrumentation  for monitoring chemical, physical, and environmental properties. Instru�  ments used in medicine and biomedical research are just as varied as those  in industry. See also analysis.</p><p>insulator Substance that blocks or retards the flow of electric current or  heat. An insulator is a poor conductor because it has a high resistance to  such flow. Electrical insulators are commonly used to hold conductors in  place, separating them from one another and from surrounding structures  to form a barrier between energized parts of an electric circuit and con�  fine the flow of current to wires or other conducting paths. Electrical  insulators include rubber, plastic, porcelain, and mica. Thermal insulators,  which break up the heat-flow path by absorbing radiant heat, include  fiberglass, cork, and rock wool.</p><p>insulin Polypeptide hormone (see peptide) that regulates blood glucose  levels. Secreted by the islets of Langerhans (see Langerhans, islets of) in  the pancreas when blood glucose rises, as after a meal, it helps transfer  the glucose into the body�s cells to be oxidized (see oxidation-reduction)  for energy or converted and stored as fatty acids or glycogen. When blood  glucose falls, insulin secretion stops and the liver releases more glucose  into the blood. Insulin has various related functions in the liver, muscles,  and other tissues, controlling the balance of glucose with related com�  pounds. Insulin-related disorders include diabetes mellitus and hypoglycemia.  Frederick Banting and J.J.R. Macleod won a Nobel Prize in 1923 for dis�  covering insulin, and Frederick Sanger won one in 1958 for determining  its amino acid sequence.</p><p>Insull Vin-solX, Samuel (b. Nov. 11, 1859, London, Eng.�d. July 19,  1938, Paris, France) British-born U.S. public-utilities magnate. He moved  to the U.S. in 1881 to become the private secretary of Thomas Alva Edi�  son and rose to become president of the Chicago Edison Co. in 1892. By  1907 he had taken control of Chicago�s transit system. By 1912 his vast  electric-power system, enlarged by various mergers, was operating sev�  eral hundred power plants. He vigorously promoted the stock of his hold�  ing companies. When they collapsed in 1932, he fled to Europe; extradited  in 1934, he was tried three times for fraud, violation of bankruptcy laws,  and embezzlement but was acquitted each time.</p><p>insurance Contract that, by redistributing risk among a large number of  people, reduces losses from accidents incurred by an individual. In return  for a specified payment (premium), the insurer undertakes to pay the  insured or his beneficiary a specified amount of money in the event that  the insured suffers loss through the occurrence of an event covered by the  insurance contract (policy). By pooling both the financial contributions  and the risks of a large number of policyholders, the insurer is able to  absorb losses much more easily than is the uninsured individual. Insurers  may offer insurance to any individual able to pay, or they may contract  with members of a group (e.g., employees of a firm) to offer special rates  for group insurance. Marine insurance, covering ships and voyages, is the  oldest form of insurance; it originated in ancient times with loans to ship�</p><p>owners that were repayable only on safe completion of a voyage, and it  was formalized in medieval Europe. Fire insurance arose in the 17th cen�  tury, and other forms of property insurance became common with the  spread of industrialization in the 19th century. It is now possible to insure  almost any kind of property, including homes, businesses, motor vehicles,  and goods in transit. See also casualty insurance; health insurance; liability  insurance; life insurance.</p><p>intaglio \in-'tal-yo\ Engraved or incised work on gemstones, glass,  ceramics, stone, or similar material in which the design is sunk beneath the  surface, the opposite of cameo and relief. It is the most ancient form of gem  engraving; the earliest known Babylonian cylinder seals date from c. 4000  bc. The term intaglio is also used to describe printmaking processes in  which the design is cut, scratched, or etched into a printing surface of cop�  per, zinc, or aluminum; ink is then rubbed into the incisions or grooves, the  surface is wiped clean, and the paper is embossed into the incised lines with  pressure from a roller press. Intaglio processes are the most versatile of  printmaking methods, as they can produce a wide range of effects.</p><p>intarsia \in-'tar-se-9\ Form of wood inlay. Italian intarsia, or inlaid  mosaic of wood, which probably derived from East Asian ivory and wood  inlay, found its richest expression during the Renaissance in Italy (c.  1400-1600). It was often used in panels over the backs of choir stalls and  in private studies and chapels of princes.</p><p>integer Whole-valued positive or negative number or 0. The integers  are generated from the set of counting numbers 1, 2, 3,... and the opera�  tion of subtraction. When a counting number is subtracted from itself, the  result is zero. When a larger number is subtracted from a smaller num�  ber, the result is a negative whole number. In this way, every integer can  be derived from the counting numbers, resulting in a set of numbers closed  under the operation of subtraction (see group theory).</p><p>integral Fundamental concept of calculus related to areas and other  quantities modeled by functions. A definite integral gives the area between  the graph of a function and the horizontal axis between vertical lines at  the endpoints of an interval. It also calculates the net change in a system  over an interval, thus leading to formulas for the work done by a varying  force or the distance traveled by an object moving at varying speeds.  When only the function is given, with no interval, it is known as an  indefinite integral. The process of solving either a definite or an indefi�  nite integral is called integration. According to the fundamental theorem of  calculus, a definite integral can be calculated by using its antiderivative  (a function whose rate of change, or derivative, equals the function being  integrated). Integrals extend to higher dimensions through multiple inte�  grals. See also line integral; surface integral.</p><p>integral, line See line integral  integral, surface See surface integral</p><p>integral calculus Branch of calculus concerned with the theory and  applications of integrals. While differential calculus focuses on rates of  change, such as slopes of tangent lines and velocities, integral calculus  deals with total size or value, such as lengths, areas, and volumes. The  two branches are connected by the fundamental theorem of calculus, which  shows how a definite integral is calculated by using its antiderivative (a  function whose rate of change, or derivative, equals the function being  integrated). For example, integrating a velocity function yields a distance  function, which enables the distance traveled by an object over an inter�  val of time to be calculated. As a result, much of integral calculus deals  with the derivation of formulas for finding antiderivatives. The great util�  ity of the subject emanates from its use in solving differential equations.</p><p>integral equation In mathematics, an equation with an unknown  function within an integral.

Early ICs  of the late 1950s consisted of about 10 components on a chip 0.12 in. (3  mm) square. Very large-scale integration (VLSI) vastly increased circuit  density, giving rise to the microprocessor. The first commercially success�  ful IC chip (Intel, 1974) had 4,800 transistors; Intel�s Pentium (1993) had  3.2 million, and more than a billion are now achievable.</p><p>integrated pest management Technique for agricultural disease-  and PEST-control in which as many pest-control methods as possible are  used in an ecologically harmonious manner to keep infestation within  manageable limits. Integrated pest management addresses the serious eco�  logical problems created by the extensive use of powerful chemical pes�  ticides. It minimizes their use and combines them with biological methods  of pest control, including the breeding of pest-resistant crop varieties, the  development of crop culture methods that inhibit pest proliferation, the  release of predators or parasites of the pest species, and the placement of  traps baited with the pest�s own sex attractants (pheromones). Chemical  insecticides generally are applied only as a last resort.</p><p>Integrated Services Digital Network See ISDN</p><p>integration In calculus, the process of finding a function whose deriva�  tive is a given function. The term, sometimes used interchangeably with  �antidifferentiation,� is indicated symbolically with the integral sign J.  (The differential dx usually follows to indicate x as the variable.) The basic  rules of integration are: (1) j(f + g)dx = \fdx + \gdx (where/and g are  functions of the variable x), (2) J kfdx = k)fdx (k is a constant), and (3)</p><p>(C is a constant). Note that any constant value may be added onto an  indefinite integral without changing its derivative. Thus, the indefinite  integral of 2x is x + C, where C can be any real number. A definite inte�  gral is an indefinite integral evaluated over an interval. The result is not  affected by the choice for the value of C. See also differentiation.</p><p>integument Un-'teg-yu-monA Covering of the body, which protects it  from the outside world and from drying out. In humans and other mam�  mals it consists of the skin (including outer epidermis and inner dermis)  and its related structures, including hair, nails, and sebaceous and sweat  glands.</p><p>Intel Corp. U.S. manufacturer of semiconductor computer circuits. Intel  was founded in 1968 as NM Electronics by Robert Noyce and Gordon  Moore, inventors of the integrated circuit, to manufacture large-scale inte�  grated (LSI) circuits. In the early 1970s it introduced the most powerful  semiconductor chips then known, which soon replaced the magnetic cores  previously used in computer memories. IBM chose to use Intel�s 8088  microprocessor (introduced 1978) in its first personal computer (the IBM  PC), and Intel microprocessors became standard for all PC-type machines.  Although other manufacturers eventually developed Intel-compatible  microprocessors, Intel continued to power more than 75% of PCs at the  beginning of the 21st century.</p><p>intellectual property Property that derives from the work of an indi�  vidual�s mind or intellect. Early copyright law aimed to protect the eco�  nomic interests of book publishers rather than the intellectual rights of  authors. Modem copyright law protects the labour of elaborating an idea,  but not the idea itself. The concept of discovery also plays a role in intel�  lectual property rights: a patent is awarded to one who can demonstrate  that he or she has invented something not previously known. The World  Trade Organization requires members to establish and enforce minimum  levels of copyright, patent, and trademark protection within their jurisdic�  tions. The World Intellectual Property Organization, which began opera�  tions in 1970, promotes the worldwide protection of both industrial  property (inventions, trademarks, and designs) and copyrighted materials  (literary, musical, photographic, and other artistic works).</p><p>intelligence In education, the ability to leam or understand or to deal  with new or challenging situations. In psychology, the term may more  specifically denote the ability to apply knowledge to manipulate one�s  environment or to think abstractly as measured by objective criteria (such  as the IQ test). Intelligence is usually thought of as deriving from a com�  bination of inherited characteristics and environmental (developmental  and social) factors. The subject remains hotly debated, and many have  tried to show that either biology (especially genes) or environment (espe�  cially conditions reflecting socioeconomic class) are more or less exclu�  sively responsible for producing differences in intelligence. Particularly  contested have been studies purporting to show links between ethnic heri�  tage and intelligence, most of which have not been accepted in the sci�  entific community. General intelligence is often said to comprise various  specific abilities (verbal ability, ability to apply logic in solving problems,  etc.), but critics contend that such compartments fail to reflect the nature  of cognition and that other models, perhaps based on information process�  ing, are needed. High intelligence (as measured by tests) is sometimes  shown to correlate with social achievement, but most experts believe other  factors are important and that intelligence is no guarantor of success (and  its lack is no guarantor of failure). See also artificial intelligence; creativity.</p><p>intelligence In government and military operations, evaluated informa�  tion concerning the strength, activities, and probable courses of action of  international actors that are usually, though not always, enemies or oppo�  nents. The term also refers to the collection, analysis, and distribution of  such information and to the secret intervention in the political or economic  affairs of other countries, an activity commonly known as �covert action.�  Intelligence is an important component of national power and a funda�  mental element in decision making regarding national security, defense,  and foreign policies. It is conducted on three levels: strategic, tactical, and  counterintelligence. Despite the public image of intelligence operatives as  cloak-and-dagger secret agents, much intelligence work involves an  undramatic search of �open� sources, such as radio broadcasts and various  publications. Among covert sources of intelligence are imagery intelli�  gence, which includes aerial and space reconnaissance, signals intelli�  gence, which includes electronic eavesdropping and code breaking, and  human intelligence, which involves the secret agent working at the classic  spy trade. Leading national intelligence organizations are the Central Intel�  ligence Agency (CIA) in the U.S.; the Federal Security Service in Russia;  MI5 and MI6 in Britain; and the Mossad in Israel.</p><p>intelligence quotient See IQ</p><p>intelligent design Argument intended to demonstrate that living  organisms were created in more or less their present forms by an �intelli�  gent designer.� Intelligent design was formulated in the 1990s, primarily in  the United States, as an explicit refutation of the Darwinian theory of bio�  logical evolution. Building on a version of the argument from design for the  existence of God, proponents of intelligent design observed that the func�  tional parts and systems of living organisms are �irreducibly complex� in  the sense that none of their component parts can be removed without caus�  ing the whole system to cease functioning. From this premise they inferred  that no such system could have come about through the gradual alteration  of functioning precursor systems by means of random mutation and natural  selection, as the standard evolutionary account maintains; therefore, living  organisms must have been created all at once by an intelligent designer.  Proponents of intelligent design generally avoided identifying the designer  with the God of Christianity or other monotheistic religions, in part because  they wished the doctrine to be taught as a legitimate scientific alternative to  evolution in public schools in the United States, where the government is  constitutionally prohibited from promoting religion. Critics of intelligent  design argued that it rests on a fundamental misunderstanding of natural  selection, that it ignores the existence of precursor systems in the evolu�  tionary history of numerous organisms, and that it is ultimately untestable  and therefore not scientific.

In knowing,  the mind is said to �intend� or �tend toward� its object, and a thing as</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>intentionality &#x25BA; intermediate goods I 947</p><p>known, or in the knowing mind, has �intentional being,� as with squar�  ing the circle, which, though impossible, can be an object of intention. In  action theory, intention is taken in a different but related sense, as in act�  ing with the intention of accomplishing a specific purpose. An important  question in action theory is that of the relation between having a specific  intention in doing something and doing the same thing intentionally. Is  an intention necessary for intentional action and, if so, is it a cause of  such action or some other kind of ground of it?</p><p>intentionality Property of being directed toward an object. Intention�  ality is exhibited in various mental phenomena. Thus, if a person expe�  riences an emotion toward an object, he has an intentional attitude toward  it. Other examples of intentional attitudes toward an object are, looking  for, believing in, and thinking about. Intentional attitudes also include  propositional attitudes. One characteristic of intentionality is �inexistence�:  A person may be intentionally related to an object that does not exist.  Thus, what a person looks for (and intentionally seeks) may not exist, and  an event he believes to occur may not occur at all. Another characteristic  is referential opacity: A sentence truly ascribing an intentional state to a  person may become false when some alternative description of the object  of that state is substituted for it. Suppose that his pen is the millionth pen  produced this year, so that �his pen� and �the millionth pen produced this  year� have the same reference. It may be true to say that he is in the inten�  tional state of searching for his pen but false to say that he is in the inten�  tional state of searching for the millionth pen produced this year; similarly,  he may believe that this is his pen and yet not believe this is the millionth  pen produced this year.</p><p>interaction, fundamental See fundamental interaction</p><p>interactionism In sociology, a theoretical perspective that derives  social processes (such as conflict, cooperation, identity formation) from  human interaction. It was Georg Simmel who first stated that �society is  merely the name for a number of individuals connected by interaction.�  In the U.S., John Dewey, Charles H. Cooley, and especially George Her�  bert Mead developed symbolic interactionism, the theory that mind and  self are not part of the innate human equipment but arise through social  interaction�i.e., communication with others using symbols. For symbolic  interactionists, the individual is always engaged in socialization or the  modification of one�s mind, role, and behaviour through contact with oth�  ers. Other theorists, such as Alfred Schutz, drew on phenomenology to  extend interactionism, an effort that led to the creation of fields such as  sociolinguistics and ethnomethodology, the study of people�s sense�  making activities. See also Erving Goffman.</p><p>interactionism In philosophy of mind, a species of mind-body dualism  that holds that mind and body, though separate and distinct substances,  causally interact. Interactionists assert that a mental event (as when a per�  son forms the intention to put his hand in a fire) can be the cause of a  physical action. Conversely, the physical event (his hand coming into  contact with the fire) can be the cause of a mental event (his feeling an  intense pain). The classical formulation of interactionism is due to Rene  Descartes, who could not satisfactorily explain how the interaction takes  place, apart from the speculation that it occurs in the pineal gland. This  problem led some philosophers to deny that mind and body really inter�  act and to explain appearances to the contrary by appealing to divine  intervention to create mental or physical effects for physical or mental  causes (see occasionalism) or to a divinely ordained �preestablished har�  mony� between the courses of mental and physical events. Benedict de  Spinoza argued for a monistic theory on which mind and body were both  attributes of a single underlying substance.

The system conveniently  expressed the measurement of a unit of space whose size varied from  building to building according to the Classical order used.</p><p>intercontinental ballistic missile See ICBM</p><p>interest Price paid for the use of credit or money. It is usually figured as  a percentage of the money borrowed and is computed annually. Interest  is charged by the lender as payment for the loss of his or her money for  a period of time. The interest rate reflects the risk of lending and is higher  for loans that are considered higher-risk, a relationship known as the risk/  return tradeoff. Like the prices of goods and services, interest rates are  responsive to supply and demand. Theories explaining the need for interest  include the time-preference theory, according to which interest is the  inducement to engage in time-consuming but more productive activities,  and the liquidity-preference theory of John Maynard Keynes, according to  which interest is the inducement to sacrifice a desired degree of liquidity  for a nonliquid contractual obligation. Interest rates may also be used as  a tool for implementing monetary policy (see discount rate). High interest  rates may dampen the economy by making it difficult for consumers,  businesses, and home buyers to secure loans, while lower rates tend to  stimulate the economy and encourage both investment and consumption.</p><p>interference In physics, the net effect of combining two or more wave  trains moving on intersecting or coincident paths. Constructive interfer�  ence occurs if two components have the same frequency and phase; the  wave amplitudes are reinforced. Destructive interference occurs when the  two waves are out of phase by one-half period (see periodic motion); if the  waves are of equal amplitude, they cancel each other. Two waves mov�  ing in the same direction but having slightly different frequencies inter�  fere constructively at regular intervals, resulting in a pulsating frequency  called a beat. Two waves traveling in opposite directions but having equal  frequencies interfere constructively in some places and destructively in  others, resulting in a standing wave.</p><p>interferon V.in-tor-'fir-.anN Any of several related proteins produced by  all vertebrates and possibly some invertebrates. They play an important  role in resistance to infection. The body�s most rapidly produced and  important defense against viruses, they can also combat bacteria and para�  sites (see parasitism), inhibit cell division, and promote or impede cell dif�  ferentiation. Interferon�s effect is indirect�it reacts with susceptible cells,  which then resist virus multiplication�in contrast to antibodies, which act  by combining directly with a specific virus. Various types of interferons  are distinguished by their characteristics as proteins and by which cells  produce them. Some are now produced by genetic engineering. Initial hopes  that interferon would be a wonder drug for a wide variety of diseases were  deflated by its serious side effects, but a few rare conditions respond to it.</p><p>interior design Design of interior spaces, closely related to architec�  ture and sometimes including interior decoration. The designer�s goal is  to produce a coordinated and harmonious whole in which the architec�  ture, site, function, and visual aspects of the interior are unified, pleasing  to mind and body, and appropriate to the activities to be pursued there.  Design criteria include harmony of colour, texture, lighting, scale, and  proportion. Furnishings must be in proportion to the space they occupy  and to the needs and lifestyles of the residents. The design of such non-  residential spaces as offices, hospitals, stores, and schools places clear  organization of functions ahead of purely aesthetic concerns.</p><p>interleukin N.in-tor-'lii-konX Any of a class of naturally occurring pro�  teins important in regulation of lymphocyte function.

They are commonly divided into continuous-combustion  engines and intermittent-combustion engines. In the first type (e.g., jet  engines) fuel and air flow steadily into the engine, where a stable flame  is maintained for continuous combustion.

Some have multiple worldwide or  regional purposes (e.g., the European Union), and some have single pur�  poses (e.g., the World Intellectual Property Organization). One effect of  their proliferation is a stronger sense of interdependence among states,  which in turn has stimulated recognition of the need for cooperation to  address international and global problems.</p><p>International Organization for Standardization (ISO) Orga�  nization for determining standards in most technical and nontechnical  fields. Founded in Geneva in 1947, its membership includes more than  100 countries. An appropriate national body represents each country; for  example, the U.S. member is the American National Standards Institute  (ANSI). Standardization affects units of measurement, alphabetization  and transliteration, and specifications for parts, materials, surfaces, pro�  cesses, tools, methods of testing, and machines. The ISO publishes the  results of its work as �International Standards� (IS). ISO standards are  optimally reviewed every five years.</p><p>international payment Payment made between countries, whether  in settlement of a trade debt, as a unilateral transfer of funds, for capital  investment, or for some other purpose. The reasons for such payments  and the methods of making them and accounting for them are matters of  concern to economists and national governments. International debts are  settled either from accumulated balances of foreign currency or claims on  foreign currency, or by loans from creditor to debtor, or by drawing on  the International Monetary Fund, or by movements of gold. How a coun�  try balances its international accounts is one of the most important deci�  sions for its BALANCE OF PAYMENTS.</p><p>International Phonetic Alphabet (IPA) Set of symbols intended  as a universal system for transcribing speech sounds. The promulgation  and updating of the IPA has been a principal aim of the International Pho�  netic Association (Association Phonetique Internationale), founded in  Paris in 1886. The first IPA chart was published in 1888. IPA symbols are  based on an extended version of the Latin alphabet, with modifications of  some letters and the use of additional symbols, some of which had been  used in earlier phonetic alphabets. Diacritics are used primarily to show  various kinds of secondary articulation.</p><p>International Refugee Organization (IRO) Temporary special�  ized agency of the United Nations system (1946-52). The IRO assisted  refugees and displaced persons in Europe and Asia who could not or  would not return home after World War II. Taking over the work of its  principal predecessor, the United Nations Relief and Rehabilitation Adminis�  tration, it also assumed responsibility for the legal protection and resettle�  ment of refugees previously carried out by the Intergovernmental  Committee on Refugees. It was succeeded by the Office of the United  Nations High Commissioner for Refugees.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>950 I international relations &#x25BA; Internet</p><p>international relations Study of the relations of states with each  other and with international organizations and certain subnational entities  (e.g., bureaucracies and political parties). It is related to a number of other  academic disciplines, including political science, geography, history, eco�  nomics, law, sociology, psychology, and philosophy. The field emerged at  the beginning of the 20th century largely in the West and particularly in  the U.S. as that country grew in power and influence. The study of inter�  national relations has always been heavily influenced by normative con�  siderations, such as the goal of reducing armed conflict and increasing  international cooperation. At the beginning of the 21st century, research  focused on issues such as terrorism, religious and ethnic conflict, the emer�  gence of substate and nonstate entities, the spread of weapons of mass  destruction and efforts to counter nuclear proliferation, and the develop�  ment of international institutions.</p><p>International Space Station (ISS) Space station assembled from  modules in Earth orbit largely by the U.S. and Russia, with assistance and  components from a multinational consortium. The project, which began  as a U.S. effort, was long delayed by funding and technical problems.  Originally called Freedom in the 1980s, it was redesigned in the 1990s  to reduce costs and expand international involvement, at which time it  was renamed. In-orbit construction started in late 1998 with the launches  of a Russian control module and a U.S.-built connecting node, which were  linked in orbit by space shuttle astronauts. In mid 2000 a habitat and  control-centre module was added, and later in the year the ISS received  its first resident crew, comprising two Russians and an American. Other  elements were subsequently joined to the station, with the overall plan  calling for a complex of laboratories and habitats crossed by a long truss  supporting four large solar power arrays. Station construction involved at  least 16 countries, including Canada, Japan, Brazil, and 11 members of  the European Space Agency. Much of the early work aboard the ISS would  focus on long-term life-sciences and material-sciences research in the  weightless environment. It was expected to serve as the basis for human  operations in Earth orbit for at least the first quarter of the 21st century.</p><p>International Standard Book Number (ISBN) Ten-digit num�  ber assigned before publication to a book or edition thereof. The ISBN  identifies various elements of the work, grouping it within a national,  geographic, language, or other convenient category and revealing its pub�  lisher, title, edition, and volume number. The ISBN is part of the Inter�  national Standard Bibliographic Description (ISBD), which was  prescribed by the International Organization for Standardization; del�  egates adopted the numbering system in 1969. The numbers are assigned  by publishers and administered by designated national standard book  numbering agencies such as the R.R. Bowker Co. in the U.S. and the  Standard Book Numbering Agency Ltd. in Britain.</p><p>International Style Architectural style that developed in Europe and  the U.S. in the 1920s and �30s and dominated Western architecture in the  mid 20th century. The term was first used in 1932 by Henry-Russell  Hitchcock and Philip Johnson in their essay �The International Style:  Architecture Since 1922.� The style�s most common characteristics are  rectilinear forms, open interior spaces, large expanses of glass, steel, and  reinforced-concrete construction, and light, taut plane surfaces devoid of</p><p>Savoye House, Poissy, Fr., an International Style residence by Le Corbusier,</p><p>1929-30</p><p>PIERRE BELZEAUX�RAPHO/PHOTO RESEARCHERS</p><p>applied ornamentation.

Adopted by the 11th General Conference on  Weights and Measures in 1960, it was developed to eliminate overlapping  but different systems of units of measures fostered by rapid advances in  science and technology in the 19th-20th centuries. Its fundamental units  include the metre (m) for length, the kilogram (kg) for mass, and the sec�  ond (sec) for time. Derived units include those for force (newton, N),  energy (joule, J), and power (watt, W). See table on opposite page.</p><p>International Telecommunication Union (ITU) United Nations  agency headquartered in Geneva. Its roots can be traced to 1865, when  the International Telegraph Union was established to coordinate interna�  tional development of the telegraph. It acquired its present name in 1934  and became a UN specialized agency in 1947. Its activities include regu�  lating allocation of radio frequencies, setting standards on technical and  operational matters, and assisting countries in developing their own tele�  communications systems.</p><p>International Telephone and Telegraph Corp. (ITT) Former  U.S. telecommunications company. It was founded in 1920 by Sosthenes  and Hemand Behn as a holding company for their Caribbean-based tele�  phone and telegraph companies. It expanded into the European market  and became a major telecommunications manufacturer. In the 1960s and  �70s ITT became a conglomerate, acquiring firms including the Sheraton  Corp. and the Hartford Fire Insurance Co. It divested its telecommunica�  tions businesses in 1987, and in 1995 it split into three companies: ITT  Hartford Group Inc. (insurance); ITT Industries Inc. (defense electronics  and auto parts); and a �new� ITT Corp., which merged with Starwood  Lodgings in 1997.</p><p>international unit Any of several precision standards used in mea�  suring physical quantities, such as mass, length, and time (see Interna�  tional System of Units), and also lighting systems, radiation processes, and  pharmacology. The luminous intensity or candlepower of a light is  expressed in candelas. The second is based on the frequency of radiation  emitted by cesium-133 atoms. In radioactive decay, the international unit  is the number of disintegrations per second in a sample. In pharmacol�  ogy, the international unit is the quantity of a substance (vitamin, hor�  mone, or toxin) that produces a specified effect when tested according to  an internationally accepted procedure.</p><p>International Whaling Commission (IWC) An intergovernmen�  tal organization created in 1946 to control the rapid escalation of whal�  ing. The original purpose of the IWC was to preserve whale stocks for  commercial whalers. Whale populations, however, continued to decline,  and in 1986 the IWC instituted a moratorium on commercial whaling that  remains in effect. At the beginning of the 21st century, 40 countries  belonged to the commission, but membership has fluctuated over the  years. The commission�s success has been limited by governments leav�  ing the IWC, ignoring its policies, or breaching regulations.</p><p>Internet Publicly accessible computer network connecting many smaller  networks from around the world. It grew out of a U.S. Defense Department  program called ARPANET (Advanced Research Projects Agency Net�  work), established in 1969 with connections between computers at the Uni�  versity of California at Los Angeles, Stanford Research Institute, the  University of California-Santa Barbara, and the University of Utah. ARPA�  NET�S purpose was to conduct research into computer networking in order  to provide a secure and survivable communications system in case of war.  As the network quickly expanded, academics and researchers in other  fields began to use it as well. In 1971 the first program for sending e-mail  over a distributed network was developed; by 1973, the year international  connections to ARPANET were made (from Britain and Norway), e-mail  represented most of the traffic on ARPANET. The 1970s also saw the devel�  opment of mailing lists, newsgroups and bulletin-board systems, and the  TCP/IP communications protocols, which were adopted as standard pro�  tocols for ARPANET in 1982-83, leading to the widespread use of the term  Internet. In 1984 the domain name addressing system was introduced. In  1986 the National Science Foundation established the NSFNET, a distrib�  uted network of networks capable of handling far greater traffic, and within  a year more than 10,000 hosts were connected to the Internet.

In 1990 ARPANET ceased to  exist, leaving behind the NSFNET, and the first commercial dial-up access  to the Internet became available. In 1991 the World Wide Web was released  to the public (via FTP). The Mosaic browser was released in 1993, and its  popularity led to the proliferation of World Wide Web sites and users. In  1995 the NSFNET reverted to the role of a research network, leaving Inter�  net traffic to be routed through network providers rather than NSF super�  computers. That year the Web became the most popular part of the Internet,  surpassing the FTP protocols in traffic volume. By 1997 there were more  than 10 million hosts on the Internet and more than 1 million registered  domain names. Internet access can now be gained via radio signals, cable-  television lines, satellites, and fibre-optic connections, though most traffic  still uses a part of the public telecommunications (telephone) network. The  Internet is widely regarded as a development of vast significance that will  affect nearly every aspect of human culture and commerce in ways still  only dimly discernible.</p><p>Internet Protocol address See IP address</p><p>Internet service provider (ISP) Company that provides Internet  connections and services to individuals and organizations.

Interpol promotes the widest possible mutual assistance between  the criminal police authorities of affiliated countries and seeks to estab�  lish and develop all institutions likely to contribute effectively to the pre�  vention and suppression of ordinary crime. The organization traces its</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>952 I interpolation &#x25BA; intonation</p><p>history to 1914, when a congress of international criminal police, attended  by delegates from 14 countries, was held in Monaco. Interpol was for�  mally founded in Austria in 1923 with 20 member countries; after World  War II its headquarters moved to Paris and, in 1989, to Lyon, France. By  the early 21st century, its membership exceeded 180 countries. Interpol  pursues criminals who operate in more than one country (e.g., smugglers),  those who stay in one country but whose crimes affect other countries  (e.g., counterfeiters of foreign currency), and those who commit a crime  in one country and flee to another.</p><p>interpolation In mathematics, estimation of a value between two known  data points. A simple example is calculating the mean (see mean, median,  and mode) of two population counts made 10 years apart to estimate the  population in the fifth year. Estimating outside the data points (e.g., pre�  dicting the population five years after the second population count) is  called extrapolation. If more than two data points are available, a curve  may fit the data better than a line. The simplest curve that fits is a poly�  nomial curve. Exactly one polynomial of any given degree�an interpo�  lating polynomial�passes through any number of data points.</p><p>interrogation In criminal law, process of formally and systematically  questioning a suspect in order to elicit incriminating responses. The pro�  cess is largely outside the governance of law, though in the U.S. relatively  elaborate safeguards have been placed on police interrogatory powers in  order to protect the rights of the accused.</p><p>interstate commerce In the U.S., any commercial transaction or traf�  fic that crosses state boundaries or that involves more than one state. Gov�  ernment regulation of interstate commerce is founded on the commerce  clause of the Constitution (Article I, section 8), which authorizes Congress  �To regulate Commerce with foreign Nations, and among the several  States, and with Indian Tribes.� The Interstate Commerce Commission, estab�  lished in 1887, was originally intended to regulate the railroad industry; its  jurisdiction was later expanded to include trucks, ships, freight forwarders,  and other interstate carriers. The Sherman Act (1890), followed by the  Clayton Act (1914), made illegal any act that tended to interfere with free  competition between and among industries, businesses, and any interstate  commercial venture. The Federal Trade Commission (FTC) was estab�  lished by the Federal Trade Commission Act of 1914, which gave the FTC  powers�judicial, legislative, and executive�to administer the Sherman  and Clayton acts. The Federal Communications Commission (FCC) was  created to protect the right of the public to the airwaves through licensing  and oversight of the practices of broadcasters in radio and television. In the  20th century, court decisions tended to interpret interstate commerce  broadly, thus allowing Congress to regulate a wide variety of activities by  which interstate commerce could be affected, even if they took place within  the borders of a single state. One such decision was Heart of Atlanta Motel  v. U.S. (1964), in which the Supreme Court upheld the prohibition of dis�  crimination in public accommodations contained in the 1964 Civil Rights  Act on the ground that the discriminatory practices of a business operating  in only one state could affect interstate commerce.</p><p>Interstate Commerce Commission (ICC) (1887-1995) First regu�  latory agency established in the U.S. and a prototype for independent  government regulatory bodies. An agency of the U.S. Department of  Transportation, it was responsible for the economic regulation of inter�  state surface transportation, including railroads, trucking companies, and  buslines. It certified carriers, regulated rates, oversaw mergers, and  approved railroad construction. The ICC was dissolved in 1995.</p><p>interstellar medium Content of the region between the stars, includ�  ing vast, diffuse clouds of gases and minute solid particles. Such tenuous  matter in the Milky Way Galaxy accounts for about 5% of its total mass.  By no means a complete vacuum, the interstellar medium contains mainly  hydrogen gas, with a smaller amount of helium and sizable quantities of  dust particles of uncertain composition. Primary cosmic rays also travel  through interstellar space, and magnetic fields extend across much of it.  Most interstellar matter occurs in cloudlike concentrations, which can  condense to form stars. Stars, in turn, continually lose mass through stel�  lar winds (see solar wind). Supernovas and planetary NEBULAe also feed mass  back to the interstellar medium, where it mixes with matter that has not  yet formed stars (see Populations I and II).</p><p>interval In music, the inclusive distance between one tone and another,  whether sounded successively (melodic interval) or simultaneously (har�  monic interval). In Western music, intervals are generally named accord�  ing to the number of scale-steps within a given key that they embrace;</p><p>thus, the ascent from C to G (C-D-E-F-G) is called a fifth because the  interval embraces five scale degrees. There are four perfect intervals:  prime, or unison; octave; fourth; and fifth. The other intervals (seconds,  thirds, sixths, sevenths) have major and minor forms that differ in size by  a half step (semitone). Both perfect and major intervals may be aug�  mented, or enlarged by a half tone. Perfect and minor intervals may be  diminished, or narrowed by a half tone.</p><p>oo A-� -e-� ^ -o-^ ^ -o-</p><p>unison | third | fifth | seventh |</p><p>second fourth sixth octave</p><p>Examples of simple musical intervals.</p><p>� MERRIAM-WEBSTER INC.</p><p>intestate succession In the law of inheritance, transmission of prop�  erty or property interests of a decedent as provided by statute, as distin�  guished from transfer according to the decedent�s will. Modern laws of  intestacy, though they vary widely, share the common principle that the  estate should devolve upon persons standing in some kinship relation with  the decedent; modern practice tends to favour the rights of the surviving  spouse.</p><p>intestinal gas Volatile material (mostly swallowed air, partly digestive  by-products) in the digestive tract, which normally contains 150-500 cc  of gas. Air in the stomach is either belched out or passed to the intestines.  Some of its oxygen is absorbed into the blood along the way. Carbon  dioxide produced by digestion is added. Nitrogen, the major component,  is inert and usually passed on. Obstructions in the small intestine can trap  gas in distended pockets, causing severe pain. In the large intestine, bac�  terial fermentation products are added�mostly hydrogen but also meth�  ane, hydrogen sulfide, ammonia, and sulfur-containing mercaptans.  Excess gas in the colon is eventually expelled from the body.</p><p>intestinal obstruction Blockage of the small intestine or large intes�  tine, resulting from either lack of peristalsis or mechanical obstruction (e.g.,  by narrowing, foreign objects, or HERNIA). Obstruction near the start of the  small intestine often causes vomiting. Near the end or in the large intes�  tine, backed-up waste and swallowed air cause intestinal distention; the  resulting pressure may cause necrosis (death of intestinal wall tissue).  Waste products may escape into the bloodstream. Symptoms and treat�  ment depend on the obstruction�s nature and location.</p><p>intestine See large intestine, small intestine</p><p>intifadah \,in-ti-'fa-d3\ Arabic "shaking off" Palestinian revolt  (1987-93, 2000- ) against the Israeli occupation in the Gaza Strip and  West Bank. Initially a spontaneous reaction to 20 years of occupation and  worsening economic conditions, it was soon taken over by the Palestine  Liberation Organization (PLO). Its tactics included strikes, boycotts, and  confrontations with Israeli troops. The International Red Cross estimated  that some 800 Palestinians, more than 200 under the age of 16, had been  killed by Israeli security forces by 1990. Several dozen Israelis were killed  during the same period. Intifadah pressure is credited with helping make  possible the 1993 Israeli-PLO agreement on Palestinian self-rule. A break�  down in further negotiations in late 2000 led to another outburst of vio�  lence, which quickly became known as the Aqsa intifadah, named for the  Aqsa Mosque in Jerusalem, where the fighting began. See also Yasir  'Arafat; Fatah; Hamas.</p><p>Intolerable Acts or Coercive Acts (1774) Four punitive measures  enacted by the British Parliament against the American colonies. Boston�s  harbour was closed until restitution was made for the tea destroyed in the  Boston Tea Party; the Massachusetts colony�s charter was annulled and a  military governor installed; British officials charged with capital offenses  could go to England for trial; and arrangement for housing British troops  in American houses was revived. The Quebec Act added to these oppres�  sive measures. The acts, called �intolerable� by the colonists, led to a  convening of the Continental Congress.</p><p>intonation In phonetics, the melodic pattern of an utterance. Intonation  is primarily a matter of variation in the pitch level of the voice (see tone),  but in languages such as English, stress and rhythm are also involved.  Intonation conveys differences of expressive meaning (e.g., surprise.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>introvert and extravert &#x25BA; investment bank I 953</p><p>doubtfulness). In many languages, including English, intonation serves a  grammatical function, distinguishing one type of phrase or sentence from  another. Thus, �it�s gone� is an assertion when spoken with a drop in pitch  at the end, but a question when spoken with a rise in pitch at the end.</p><p>introvert and extravert Basic personality types, according to the  theories of Carl Gustav Jung. The introvert, who directs thoughts and  feelings inward, is often shy, contemplative, and reserved. The extravert,  who directs attention toward other people and the outside world, is usu�  ally outgoing, responsive, and aggressive. This typology is now regarded  as simplistic because almost no one can be described as wholly introverted  or extraverted.</p><p>intrusive rock Igneous rock formed from magma forced into older rocks  at depths within the Earth�s crust, which then slowly solidifies below the  Earth�s surface, though it may later be exposed by erosion. Igneous intru�  sions form a variety of rock types. See also extrusive rock.</p><p>intuition In philosophy, the power of obtaining knowledge that is not  or cannot be acquired either by inference or observation. As such, intu�  ition is thought of as an original, independent source of knowledge, since  it is designed to account for just those kinds of knowledge that other  sources do not provide. Knowledge of some necessary truths and basic  moral principles is sometimes explained in this way. A technical sense of  intuition, deriving from Immanuel Kant, refers to immediate acquaintance  with individual entities; intuition ( Anschauung ) in this sense may be  empirical (e.g., consciousness of sense-data) or pure (e.g., consciousness  of space and time a priori as forms of all empirical intuitions). As con�  ceived by Benedict de Spinoza and Henri Bergson, intuition is taken to be  concrete knowledge of the world as an interconnected whole, as con�  trasted with the piecemeal, �abstract� knowledge obtained by science and  observation.</p><p>intuitionism School of mathematical thought introduced by the Dutch  mathematician Luitzen Egbertus Jan Brouwer (1881-1966). In contrast  with mathematical Platonism, which holds that mathematical concepts  exist independent of any human realization of them, intuitionism holds  that only those mathematical concepts that can be demonstrated, or con�  structed, following a finite number of steps are legitimate. Few mathema�  ticians have been willing to abandon the vast realms of mathematics built  with nonconstructive proofs.</p><p>intuitionism In metaethics, a form of cognitivism that holds that moral  statements can be known to be true or false immediately through a kind  of rational intuition. In the 17th and 18th centuries, intuitionism was  defended by Ralph Cudworth, Henry More (1614-87), Samuel Clarke  (1675-1729), and Richard Price (1723-91); in the 20th century its sup�  porters included H.A Prichard (1871-1947), G.E. Moore, and David Ross.  Intuitionists have differed over the kinds of moral truths that are ame�  nable to direct apprehension. For example, whereas Moore thought that  it is self-evident that certain things are morally valuable, Ross thought  that we know immediately that it is our duty to do acts of a certain type.</p><p>Inuit See Eskimo</p><p>Invar Trademark name for an alloy of iron (64% iron, 36% nickel) that  expands very little when heated. Invar was formerly used for absolute  standards of length measurement and is now used for surveying tapes and  in watches and various other temperature-sensitive devices. The name  expresses the invariability of its dimensions. It was developed by Charles-  Edouard Guillaume (1861-1938), winner of the 1920 Nobel Prize for  Physics.</p><p>inventory In business, any item of property held in stock by a firm,  including finished goods held for sale, goods in the process of production,  raw materials, and items that will be consumed in the process of produc�  ing salable goods. Inventories appear on a company�s balance sheet as  assets. Inventory turnover, which indicates the rate at which goods are  converted into cash, is a key factor in appraising a firm�s financial con�  dition. For financial statements, inventories may be priced either at cost  or at market value.</p><p>Inverness \,in-v9r-'nes\ Royal burgh (pop., 2001: 44,084), Highland  council area, in the historic county of Inverness-shire, northwestern Scot�  land. Located on the River Ness and the Caledonian Canal, it has long  been the centre of the Scottish Highlands. In the 6th century it was the  capital of the Pictish king Brude. By the 12th century it had become a  burgh near the castle of Malcolm III Canmore. Inverness is now an edu�</p><p>cational and tourist centre. Its manufacturing has expanded in conjunc�  tion with the growth of offshore oil production.</p><p>inverse function Mathematical function that undoes the effect of  another function. For example, the inverse function of the formula that  converts Celsius temperature to Fahrenheit temperature is the formula that  converts Fahrenheit to Celsius. Applying one formula and then the other  yields the original temperature. Inverse procedures are essential to solv�  ing equations because they allow mathematical operations to be reversed  (e.g. logarithms, the inverses of exponential functions, are used to solve  exponential equations). Whenever a mathematical procedure is intro�  duced, one of the most important questions is how to invert it. Thus, for  example, the trigonometric functions gave rise to the inverse trigonomet�  ric functions.</p><p>invertebrate Any animal that lacks a vertebral column, or backbone.  They include the protozoans, annelids, cnidarians, echinoderms, flatworms,  nematodes, mollusks, and arthropods. More than 90% of living animals are  invertebrates. Worldwide in distribution, they range in size from minute  protozoans to giant squids. Apart from the absence of a vertebral column,  invertebrates have little in common. They are generally soft-bodied and  have an external skeleton for muscle attachment and protection. See also  VERTEBRATE.</p><p>Investiture Controversy Struggle between the papacy and the secu�  lar rulers of Europe over the latter�s presentation of the symbols of office  to churchmen. Pope Gregory VII condemned lay investiture in 1078 as an  unjustified assertion of secular authority over the church; the issue was  pivotal in his dispute with King Henry IV and in the larger struggle over  Henry�s refusal to obey papal commands. Henry successfully drove Gre�  gory from Rome and installed an antipope, but it would be Gregory�s  rejection of lay investiture that would ultimately prevail. Henry I of  England renounced lay investiture (1106) in return for the guarantee that  homage would be paid to the king before consecration, and the Concor�  dat of Worms (1122) forged a similar compromise between Henry V and  Calixtus II.</p><p>investment Process of exchanging income for an asset that is expected  to produce earnings at a later time. An investor refrains from consumption  in the present in hopes of a greater return in the future. Investment may  be influenced by rates of interest, with the rate of investment rising as  interest rates fall, but other factors more difficult to measure may also be  important�for example, the business community�s expectations about  future demand and profit, technical changes in production methods, and  expected relative costs of labour and capital. Investment cannot occur  without saving, which provides funding. Because investment increases an  economy�s capacity to produce, it is a factor contributing to economic  growth.</p><p>investment bank Firm that originates, underwrites, and distributes  new security issues of corporations and government agencies. The Banking</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>954 I investment casting &#x25BA; Ionian</p><p>Act of 1933 required the separation of investment banking and commercial  BANKing functions. Investment banks operate by purchasing all the new  securities issued by a corporation at one price and selling fractions of the  new issue to the investing public at prices high enough to yield a profit. The  investment bank is responsible for setting the public offering price, which  it bases on probable demand and assessments of the economic climate. A  syndicate of investment banking firms underwrites and distributes most  security issues in order to divide the risk of the new issue. An initial public  offering (IPO) refers to the issuance of the first public shares of a formerly  nonpublic company. See also bank; central bank; savings bank; security.</p><p>investment casting Precision casting for forming metal shapes with  minutely precise details. Casting bronze or precious metals typically  involves several steps, including forming a mold around the sculptured  form; detaching the mold (in two or more sections); coating its inside with  wax; forming a second mold, of heat-resisting clay, around the wax shell,  and filling the interior with a clay core; baking the assembly (hardening  the clay and melting the wax, which escapes through openings in the outer  mold); pouring molten bronze into the space vacated by the wax; and  breaking the mold to expose the cast form. In modern foundries, plastics,  or occasionally frozen mercury, are used instead of wax. See also lost-  wax CASTING, DIE CASTING.</p><p>investment credit or investment tax credit Tax incentive that  permits companies or individuals to deduct a specified percentage of cer�  tain investment costs from their tax liability in addition to the normal  allowances for depreciation. Investment credits are similar to investment  allowances, which permit investors or businesses to deduct a specified  percentage of certain capital costs from taxable income. Both investment  credits and investment allowances differ from accelerated depreciation by  offering a percentage deduction at the time an asset is purchased. In effect,  the credits are subsidies for investment. Investment credits and investment  allowances were adopted by the U.S. in 1962 in order to protect domes�  tic business from foreign competition but have since been applied toward  the support of energy conservation, pollution control, or various forms of  desirable economic development.</p><p>investment trust or closed-end trust Financial organization that  pools the funds of its shareholders and invests them in a diversified port�  folio of securities. It differs from a mutual fund, which issues units repre�  senting diversified holdings rather than shares in the company itself.  Investment trusts have a fixed number of shares for sale; their price  depends on the market value of the underlying securities and on the  demand for and supply of shares. The first modern investment trusts were  formed in England and Scotland as early as 1860. Many early U.S. invest�  ment trusts failed with the collapse of the stock market in 1929, but oth�  ers have since prospered under stricter federal regulation.</p><p>lo \'I-o\ In Greek mythology, the daughter of the river god Argos. Io drew  Hera�s jealousy when Zeus fell in love with her. Zeus changed her into a  white heifer to protect her. Hera sent the many-eyed creature Argus to  watch over the heifer, but Zeus sent Hermes to lull Argus to sleep and kill  him. Hera then sent a gadfly to pursue Io, who fled across Europe and  crossed the bodies of water later named the Ionian Sea and the Bosporus  (�Ford of the Cow�) in her honour. When she arrived in Egypt she resumed  her original form. She was later identified with the Egyptian goddess Isis.</p><p>iodine Nonmetallic chemical element, chemical symbol I, atomic num�  ber 53. The heaviest nonradioactive halogen, it is a nearly black crystal�  line solid (diatomic molecule I 2 ) that sublimes (see sublimation) to a deep  violet, irritating vapour. It is never found in nature uncombined. Its  sources (mostly in brines and seaweeds) and compounds are usually  iodides; iodates (small amounts in saltpeter) and periodates also occur.  Dietary iodine is essential for thyroid gland function; in areas of the world  where food contains insufficient iodine, an iodine compound such as  potassium iodide (KI) is added to table salt (sodium chloride) to prevent  iodine deficiency. Elemental iodine is used in medicine, in synthesizing  some organic chemicals, in manufacturing dyes, in analytical chemistry  (see analysis) to measure fat saturation (see hydrogenation) and to detect  starch, and in photography. The radioactive isotope iodine-131 (see radio�  activity), with an eight-day half-life, is very useful in medicine (see nuclear  medicine) and other applications.</p><p>iodine deficiency Inadequate intake or metabolism of iodine. It  directly affects thyroid secretions, which influence heart action, nerve  response, growth rate, and metabolism. Simple goitre, the most frequent  result, is most common in areas without access to salt water and is rare</p><p>along seacoasts. Severe, prolonged deficiency can cause hypothyroidism.  Eating seafood regularly or using iodized table salt will prevent iodine  deficiency. Some countries have made dietary iodine additives mandatory.</p><p>ion Atom or group of atoms with one or more positive or negative elec�  tric charges. Positively charged ions are cations, negatively charged ones  anions. Ions are formed when electrons are added to or removed from  neutral molecules or other ions, as sodium (Na) and chlorine (Cl) atoms  react to form Na + and Cl - ; when ions combine with other particles, as  hydrogen cations (H + ) and ammonia (NH 3 ) combine to form ammonium  cations (NH 4 + ); or when a covalent bond between two atoms is ruptured  in such a way that the resulting particles are charged, as water (H 2 0) dis�  sociates (see dissociation) into hydrogen and hydroxide ions (H + and  OH - ). Many crystalline substances (see crystal) are composed of ions held  in regular geometric patterns by the attraction of oppositely charged par�  ticles for each other. Ions migrate to the electrode of opposite charge in  an electric field and are the conductors of current in electrolytic cells (see  electrolysis). Compounds that form ions are called electrolytes. Ions are  also formed in gases when heated to very high temperatures or when an  electrical discharge passes through them (see plasma).</p><p>ion-exchange resin Any of a wide variety of synthetic polymers con�  taining positively or negatively charged sites that can interact with or bind  to an ion of opposite charge from a surrounding solution. Light, porous  solids in granules, beads, or sheets, they absorb the solution and swell as  they attract the target ions; when exhausted, they are removed from use  and regenerated by an inexpensive brine or carbonate solution. A solid  support of styrene-divinylbenzene copolymer to which are attached sul�  fonic or carboxylic acid groups is often used to attract and exchange cat�  ions (e.g., ions of hydrogen or metals). Quaternary ammonium groups on  the solid matrix are used to attract anions (e.g., ions of chlorine). Indus�  trially, the resins are used to soften hard water, purify sugar, and concen�  trate valuable elements (gold, silver, uranium) from their ores. In the  laboratory they are used to separate and concentrate substances and some�  times as catalysts. Zeolites are minerals with ion-exchange properties.</p><p>Ionesco \yo-nes-'ko\ / Eugene orig. Eugen lonescu (b. Nov. 26,  1909, Slatina, Rom.�d. March 28,</p><p>1994, Paris, France) Romanian-born  French playwright. He studied in  Bucharest and Paris, where he lived  from 1945. His first one-act �anti�  play,� The Bald Soprano (1950),  inspired a revolution in dramatic  techniques and helped inaugurate the  Theatre of the Absurd. He followed it  with other one-act plays in which  illogical events create an atmosphere  both comic and grotesque, including  The Lesson (1951), The Chairs  (1952), and The New Tenant (1955).</p><p>His most popular full-length play,</p><p>Rhinoceros (1959), concerns a pro�  vincial French town in which all the  citizens are metamorphosing into  rhinoceroses.

He was elected to the  Academie Fran�aise in 1970.</p><p>Ionia M-'o-nyoV Ancient region, western coast of Asia Minor (modem  Turkey) bordering the Aegean Sea. It consisted of a coastal strip that  extended from the mouth of the Hermus River to the Halicarnassus Pen�  insula, a distance of 100 mi (160 km). In the 8th century bc there were 12  major Greek cities in the region, including Phocaea, Erythrae, Colophon,  and Miletus on the mainland, and the islands Chios and Samos. It was very  prosperous, and until 500 bc Ionic philosophy and architecture and the  Ionic dialect were highly influential in Greece. In the mid-6th century bc  it fell to Lydia and then to the Persians. After a brief period of independence  beginning in 334 bc, it became part of the Seleucid kingdom. In 133 bc it  passed to the Romans and became part of the Roman province of Asia. It  was devastated during the Turkish conquest of Asia Minor.</p><p>Ionian Any ancient Greek inhabitant of Ionia, from the time of the col�  lapse of Mycenae. Ionian cities colonized southern Italy and opened up  the Black Sea from c. 700 bc. Their contributions to Greek culture</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Ionian &#x25BA; IQ I 955</p><p>included the epics of Homer and the earliest elegiac and iambic poetry.  They began the study of geography, philosophy, and historiography in the  6th century. After Alexander the Great their literary language was the basis  of Koine, or �common speech,� the language of practically all Greek writ�  ing to the present day.</p><p>Ionian \I-'o-ne-3n\ Islands ancient Heptanesos Group of seven  Greek islands (pop., 2001: 214,274) in the Ionian Sea. They include  Corfu, Cephalonia, Zacynthus, Leucas, Ithaca, Cythera, and Paxos and  have a combined land area of 891 sq mi (2,307 sq km). Controlled by  Venice in the 15th and 16th centuries, they were taken by Russian and  Turkish forces in 1799. In 1815 the Treaty of Paris placed them under the  control of Britain; the British ceded them to Greece in 1864.</p><p>Ionian revolt Uprising (499-494 bc) of some of the Ionian cities of  Asia Minor against their Persian overlords. The cities deposed their own  tyrants and, with help from Athens, tried unsuccessfully to throw off Per�  sian domination. Darius I of Persia used Athens�s involvement as a pre�  text for his invasion of Greece in 490, initiating the Persian Wars, which  resulted in a stronger Athenian influence in western Anatolia.</p><p>Ionian school School of Greek philosophers of the 6th-5th century bc,  including Thales, Anaximander, Anaximenes, Heracleitus, Anaxagoras, Dio�  genes of Apollonia, Archelaus, and Hippon. Though Ionia was the origi�  nal center of their activity, they differed so greatly from one another in  their conclusions that they cannot truly be said to represent a specific  school of philosophy, but their common concern to explain phenomena  in terms of matter or physical forces distinguished them from later think�  ers.</p><p>Ionian Sea Part of the Mediterranean Sea lying between Greece, Sic�  ily, and Italy. Though once considered part of the Adriatic Sea, to which  it connects by the Strait of Otranto, it is now considered a separate body.  The Mediterranean reaches its greatest depth (16,000 ft or 4,900 m) in the  Ionian south of Greece. Along its eastern shore are the Ionian Islands.</p><p>ionic bond Electrostatic attraction between oppositely charged ions in  a chemical compound. Such a bond forms when one or more electrons are  transferred from one neutral atom (typically a metal, which becomes a  cation) to another (typically a nonmetallic element or group, which  becomes an anion). The two types of ion are held together by electrostatic  forces in a solid that does not comprise neutral molecules as such; rather,  each ion has neighbours of the opposite charge in an ordered overall crys�  talline structure. When, for example, crystals of common salt (sodium  chloride, NaCl) are dissolved in water, they dissociate (see dissociation)  into two kinds of ions in equal numbers, sodium cations (Na + ) and chlo�  ride anions (Cl - ). See also bonding; covalent bond.</p><p>ionization Process by which electrically neutral atoms or molecules are  converted to electrically charged atoms or molecules (ions) by the removal  or addition of negatively charged electrons. It is one of the principal ways  in which radiation transfers energy to matter, and hence of detecting radia�  tion. In general, ionization occurs whenever sufficiently energetic charged  particles or radiant energy travels through gases, liquids, or solids. A cer�  tain minimal level of ionization is present in the earth�s atmosphere  because of continuous absorption of cosmic rays from space and ultravio�  let radiation from the sun.</p><p>ionization potential or ionization energy Amount of energy  required to remove an electron from an isolated atom or molecule. There  is an ionization potential for each successive electron removed, though  that associated with removing the first (most loosely held) electron is most  commonly used. The ionization potential of an element is a measure of its  ability to enter into chemical reactions requiring ion formation or dona�  tion of electrons and is related to the nature of the chemical bonding in  the compounds formed by elements. See also binding energy, ionization.</p><p>ionosphere M-'an-a-.sfirX Region of the Earth�s atmosphere in which  the number of ions, or electrically charged particles, is large enough to  affect the propagation of radio waves. The ionosphere begins at an alti�  tude of about 30 mi (50 km) but is most distinct above about 50 mi (80  km). The ionization is caused mainly by solar radiation at X-ray and ultra�  violet wavelengths. The ionosphere is responsible for the long-distance  propagation, by reflection, of radio signals in the shortwave and broad�  cast bands.</p><p>Iowa State (pop., 2000: 2,926,324), midwestem U.S. Bordered by Min�  nesota, Wisconsin, Illinois, Missouri, Nebraska, and South Dakota, it cov�</p><p>ers 56,276 sq mi (145,755 sq km). Its capital is Des Moines. The Des  Moines River flows across the state from northwest to southeast. The Mis�  sissippi River forms its eastern boundary, while the Missouri River and the  Big Sioux River define portions of its western boundary. The Sauk, Fox,  Iowa, and Sioux Indians lived in the region when French explorers Louis  Jolliet and Jacques Marquette arrived in 1673. The U.S. acquired Iowa as  part of the Louisiana Purchase in 1803. Following the Black Hawk War  and purchase of eastern Iowa from the Sauk and Fox Indians in the 1830s,  white settlement advanced rapidly. Iowa became a territory in 1838 and  was made the 29th state in 1846. After the Civil War, railroad expansion  drew large waves of immigrants from the east and from Europe. After  World War I population growth slowed. Its economy is based on agricul�  ture, and Iowa is a leader in the U.S. production of livestock.</p><p>IP address in full Internet Protocol address Number that  uniquely identifies each computer on the Internet. A computer�s IP address  may be permanently assigned or supplied each time that it connects to the  Internet by an Internet service provider.

When the  Achaean fleet was becalmed at Aulis, Iphigeneia�s father sacrificed her to  Artemis in order to secure favourable winds to carry the ships to Troy. Her  mother later avenged her death by murdering Agamemnon. Iphigeneia�s  story is treated in plays by Aeschylus, Sophocles, and Euripides. According  to Euripides, she did not die but was saved by Artemis; she went to the  land of Tauris, where she became a priestess, and she saved Orestes from  madness and death when he fled there after killing their mother.</p><p>Ipoh \'e-po\ City (pop., 2000 prelim.: 566,211), western Malaysia. Its  name comes from a local tree, whose poisonous resin was once used by  indigenous people for hunting. The modern city dates from the 1890s,  when British tin-mining companies were set up. Immigrant Chinese were  brought in to work the tin deposits, and their descendants now dominate  the city.

It is now an agricultural  market and service centre. Its landmarks include the 16th-century  Christchurch mansion and the Great White Horse coaching inn mentioned  in Charles Dickens�s The Pickwick Papers. It was the birthplace of Tho�  mas Cardinal Wolsey.</p><p>IQ in full intelligence quotient Number intended to represent a mea�  sure of relative intelligence as determined by the subject�s responses to a  series of test problems. The IQ was originally computed as the ratio of a  person�s mental age to his or her chronological (physical) age, multiplied  by 100, but use of the concept of mental age has been largely discontin�  ued, and IQ is now generally assessed on the basis of the statistical dis�  tribution of scores. The most widely used intelligence tests are the  Stanford-Binet test (1916), for children, and the Wechsler test (1939),  originally for adults but now also for children. A score above 130 is con�  sidered to reflect �giftedness,� while a score below 70 is considered to  reflect mental impairment or mental retardation. Intelligence tests have  provoked great controversy, particularly about what kinds of mental abil�  ity constitute intelligence and whether IQ adequately represents these  abilities, and about cultural and class bias in test construction and stan�  dardization procedures.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>956 I Iqaluit &#x25BA; Iranian languages</p><p>Iqaluit \e-'ka-lu-it\ formerly Frobisher Bay Town (pop., 2001:  5,236), capital of Nunavut territory, Canada.

Iran occupies a high plateau,  rising higher than 1,500 ft (460 m) above sea level, and is surrounded  largely by mountains. More than half of its surface area consists of salt  deserts and other wasteland. About one-tenth of its land is arable, and  another one-fourth is suitable for grazing. Iran�s rich petroleum reserves  account for about one-tenth of world reserves and are the basis of its  economy. It is an Islamic republic with one legislative house and several</p><p>oversight bodies dominated by clergy. The head of state and government  is the president, but supreme authority rests with the rahbar, a ranking  cleric. Human habitation in Iran dates to some 100,000 years ago, but  recorded history began with the Elamites c. 3000 bc. The Medes flour�  ished from c. 728 but were overthrown in 550 by the Persians, who were  in turn conquered by Alexander the Great in the 4th century bc. The  Parthians (see Parthia) created an empire that lasted from 247 bc to ad  226, when control passed to the Sasanian dynasty. Various Muslim dynas�  ties ruled from the 7th century. In 1501 the Safavid dynasty was estab�  lished and lasted until 1736. The Qajar dynasty ruled from 1796, but in  the 19th century the country was economically controlled by the Russian  and British empires. Reza Khan (see Reza Shah Pahlavi) seized power in  a coup (1921). His son Mohammad Reza Shah Pahlavi alienated religious  leaders with a program of modernization and Westernization and was  overthrown in 1979; ShTite cleric Ruhollah Khomeini then set up an Islamic  republic, and Western influence was suppressed. The destructive Iran-Iraq  War of the 1980s ended in a stalemate. Since the 1990s the government  has gradually moved to a more liberal conduct of state affairs.</p><p>Iran-Contra Affair U.S. political scandal. In 1985 Robert McFarlane,  head of the National Security Council (NSC), authorized sales of weap�  ons to Iran in an attempt to secure the release of U.S. hostages held in  Lebanon by pro-Iranian terrorist groups. The deal contravened stated  policy regarding both dealings with terrorists and military aid to Iran. At  the instigation of Oliver North, a NSC staff member, and with the approval  of John M. Poindexter, part of the $48 million paid by Iran for the arms  was diverted to the Nicaraguan contras, in direct violation of a 1984 law  banning such assistance. A Senate investigation resulted in the conviction  of North and Poindexter on charges of obstructing justice and related  offenses, though their convictions were later overturned on the ground  that testimony given at their trials had been influenced by information  they had supplied to Congress under a limited grant of immunity. Pres.  Ronald Reagan accepted responsibility for the arms-for-hostages deal but  denied any knowledge of the diversion.</p><p>Iran hostage crisis (1979-81) Political crisis involving Iran�s deten�  tion of U.S. diplomats. Anti-American sentiment in Iran�fueled in part  by close ties between the U.S. and the unpopular leader Mohammad Reza  Shah Pahlavi �peaked when Pahlavi fled Iran during the 1979 Iranian  revolution. When the monarch entered the U.S. for medical treatment later  that year, Islamic militants stormed the U.S. embassy in Tehran and seized  66 Americans. The hostage-takers, who enjoyed the tacit support of the  new Iranian regime of Ruhollah Khomeini, demanded the shah�s extradi�  tion to Iran, but Pres. Jimmy Carter refused and froze all Iranian assets in  the U.S. The Iranians released 13 women and African Americans on Nov.  19-20, 1979, and another hostage was released in July 1980. A rescue  attempt in April 1980 failed. Negotiations for the hostages� return began  after the shah died in July 1980, but the remaining 52 hostages were kept  in captivity until Jan. 20, 1981, when they were released moments after  the inauguration of Ronald Reagan. The crisis contributed to Carter�s fail�  ure to win reelection.

Following the 1979 Iranian  revolution, the Iraqi leadership sought to exploit Iran�s military and politi�  cal chaos in order to resolve border disputes, gain control of Iran�s oil-  rich western (largely Arab) province, and achieve hegemony in the Persian  Gulf. Iraq was successful early (1980-82) but began to lose ground and  sought to negotiate peace. Iran refused, and the war turned into a bloody  stalemate that included the first use of chemical warfare since World War  I (1914-18). After additional Iraqi advances, Iran agreed to a cease-fire  in 1988. Peace was concluded only when Iraq invaded another neighbour,  Kuwait, in 1990.

Nearly all the Modern Iranian languages have been written�if at  all�in adaptations of the Arabic alphabet.</p><p>Iranian religions Ancient religions of the peoples of the Iranian pla�  teau. The Medes and Persians were dominated by a powerful priestly tribe,  the magi. The magi were responsible for chanting accounts of the origin  and descent of the gods, and they were probably the source of the dualism  that later characterized Zoroastrianism, the best known of the Iranian reli�  gions. The chief god of the pre-Zoroastrian pantheon was Ahura Mazda,  the creator of the universe and the one who maintains the cosmic and  social order. Mithra was the second most important deity and the protec�  tor of covenants. Other major deities included Anahita, the war goddess;  Rashnu, the god of justice; and astral deities such as Tishtrya, identified  with the star Sirius. The ancient Iranians did not build temples or make  images of their gods, preferring to worship in the open. The central ritual  was the ycizna, which consisted of a festive meal at which the worshipers  made animal sacrifices and invited the deity to attend as a guest. Fire was  regarded as a sacred element. The sacred drink hauma, which contained  a mind-altering drug, was used to inspire worshipers with insight into truth  and to stimulate warriors going into battle.</p><p>Iraq officially Republic of Iraq Country, Middle East, southwestern  Asia, northwest of the Persian Gulf. Area: 167,618 sq mi (434,128 sq km).  Population (2005 est.): 27,818,000. Capital: Baghdad. The population con�</p><p>sists mainly of an Arab majority and a Kur-  Dish minority. Language: Arabic (official).  Religions: Islam (official; mostly Shfite);  also Christianity. Currency: dinar. The  country can be divided into four major  regions: the Tigris-Euphrates alluvial plains in central and southeastern  Iraq; Al-Jazlrah, an upland region in the north between the Tigris and  Euphrates rivers; deserts in the west and south, covering about two-fifths  of the country; and highlands in the northeast. Iraq has the world�s sec�  ond largest proven reserves of petroleum, and it has substantial reserves  of natural gas. Agriculture is also a major component of the economy.  Iraq has a transitional government with one legislative house; its head of  state is the president. Called Mesopotamia in Classical times, the region  gave rise to the world�s earliest civilizations, including those of Sumer,  Akkad, and Babylon. Conquered by Alexander the Great in 331 bc, the area  later became a battleground between Romans and Parthians, then between  Sasanians and Byzantines. Arab Muslims conquered it in the 7th century  ad, and various Muslim dynasties ruled until the Mongols took over in</p><p>The Ottoman Empire took control in the 16th century and ruled until  the British occupied the country during World War I (1914-18). The Brit�  ish created the kingdom of Iraq in 1921 and occupied Iraq again during  World War II (1939-45). The monarchy was restored following the war,  but a revolution caused its downfall in 1958. Following a series of mili�  tary coups, the socialist Ba'th Party, eventually led by Saddam Hussein, took  control and established totalitarian rule in 1968. The I ran-Iraq War in the  1980s and the First Persian Gulf War in 1990-91 caused extensive death  and destruction. The economy languished under a UN economic embargo  imposed on Iraq in the 1990s. The embargo began to erode by the early  21st century, and in 2003, during the Second Persian Gulf War, the Ba'th  Party was driven from power.</p><p>Irbid Town (pop., 1994: 208,329), northern Jordan.

His family immigrated to North  Carolina, where he was appointed comptroller of the customhouse at age  17. He helped draft and revise the laws of the new state of North Carolina  and served as state attorney general (1779-81). He led the state�s Federal�  ists in supporting ratification of the U.S. Constitution, and his letters in its  defense (signed �Marcus�) are said to have prompted Pres. George Wash�  ington to appoint him to the U.S. Supreme Court (1790). He wrote several  notable dissents, including those for Chisholm v. Georgia (1793; affirming  the subordination of the states to the federal government) and Ware v. Hyl�  ton (1796; upholding the primacy of U.S. treaties over state statutes).

High technology, tour�  ism, and other service industries are pivotal to the Irish economy, while  mining, manufacturing, and construction also remain important. Ireland is  a republic with two legislative houses; its chief of state is the president, and  the head of government is the prime minister. Human settlement in Ireland  began c. 6000 bc, and Celtic migration dates from c. 300 bc. St. Patrick is  credited with having Christianized the country in the 5th century. Norse  domination began in 795 and ended in 1014, when the Norse were defeated  by Brian Boru. Gaelic Ireland�s independence ended in 1175 when Roderic  O�Connor, Ireland�s high king, accepted English King Henry II as his over-  lord. Beginning in the 16th century, Irish Catholic landowners fled reli�  gious persecution by the English and were replaced by English and Scottish  Protestant migrants. The United Kingdom of Great Britain and Ireland was  established in 1801. The Irish Potato Famine of the 1840s led as many as  1.5 million people to emigrate, and the British government�s grudging and  ineffective relief measures built momentum for Irish Home Rule. The Easter  Rising (1916) was followed by virtual civil war (1919-21), during which  the Irish Republican Army used guerrilla tactics to force the British gov�  ernment to negotiate. The Catholic majority in southern Ireland favoured  complete independence, and the Protestant majority in the north preferred  continued union with Britain. Southern Ireland was granted dominion sta�  tus and became the Irish Free State in 1921, and in 1937 it adopted the name  Eire (Ireland) and became a sovereign independent country. It remained  neutral during World War II. Britain recognized the status of Ireland in  1949 but declared that cession of the northern six counties (Northern Ire�  land) could not occur without the consent of the Parliament of Northern  Ireland. In 1973 Ireland joined the European Economic Community (later  the European Community); it is now a member of the European Union. The  last decades of the 20th century were dominated by sectarian hostilities  between the island�s Catholics and Protestants over the status of Northern  Ireland. The Irish government played a pivotal role in negotiating and win�  ning public support for the Belfast Agreement (1998), which gave the  country a consultative role in the affairs of Northern Ireland and modified  Ireland�s constitution to remove its claim to the territory of the entire  island.</p><p>Ireland, Northern See Northern Ireland</p><p>Irenaeus V.i-ro-'ne-os, J-ro-'na-ssV Saint (b. c. 120/140, Asia  Minor�d. c. 200/203, probably Lyon; Western feast day June 28; East�  ern feast day August 23) Bishop and theologian. Bom of Greek parents,  he was a missionary to Gaul before being named bishop of Lugdunum  (modern Lyon, France). All his major works, including Against Heresies,  were written in opposition to Gnosticism. To counteract Gnostic influence,  he promoted the development of an authoritative canon of the New Tes�  tament. His defense of the belief that the Christian God and the God of  the Old Testament were identical led to the development of the Apostles�  Creed. His writings against the Gnostics also supported the authority of  the bishops, and he claimed that the bishops of various cities were known  as far back as the Apostles (see apostolic succession). His works have  proved a valuable source of information on the Gnostics, because he gave  accurate summaries of their beliefs before refuting them.</p><p>Ireton \'Ir-t 3 n\, Henry (b. 1611, Attenborough, Nottinghamshire,  Eng.�d.

Join�  ing the Parliamentary army at the outbreak of war, he was involved in  many victories. He was elected to Parliament in 1645 and married Oliver  Cromwell�s daughter in 1646. In 1647 he proposed a scheme for a con�  stitutional monarchy; after its rejection by Charles I, Ireton provided the  ideological foundations for the assault on the monarchy. He helped bring  Charles to trial and was one of the signers of his death warrant.

A very rare, precious, sil�  very white, hai'd, brittle metal that resists most acids, it is one of the densest  substances known on Earth. It probably does not occur uncombined in  nature but is found in natural alloys with other noble (i.e., chemically  inactive or inert) metals. The pure metal is too hard to work with to have  any significant uses; alloys with platinum are used in jewelry, pen points,  surgical pins and pivots, electrical contacts and sparking points, and extru�  sion dies. The international prototype kilogram, the primary standard (see  weights and measures) for weight, is made of an alloy comprising 90%  platinum and 10% iridium. The discovery of abnormally high amounts of  iridium in rocks dating to the boundary between the Cretaceous and Ter�  tiary periods led to a much-debated hypothesis that an iridium-containing  asteroid striking Earth led to a catastrophic chain of events including the  extinction of dinosaurs and many other forms of life.</p><p>Irigaray \e-re-ga-'ra,\ English Vir-i-.gar-eX, Luce (b. 19327, Belgium)  French feminist psychoanalyst and philosopher.

Working  relentlessly for electoral reform, he succeeded in 1912 in securing a  secret-ballot vote. When he was elected president in 1916, he passed  measures regulating labour conditions but failed to enforce them, and a  serious strike was violently broken in 1919. Corruption and the failure to  implement democratic reforms cost him support after his return to power  in 1928, and he was further weakened by the Great Depression. A nearly  bloodless military coup ended his career.</p><p>iris family Family Iridaceae, composed of about 1,700 species of peren�  nial herbaceous plants, as well as a few shrubs, in some 80 genera. It is  known for ornamentals such as irises (genus Iris), gladioli (see gladiolus),  CROCUSes, and freesias. Irises have swordlike, smooth leaves and bear  showy flowers in a great variety of colours and sizes on a smooth stem.  Most abundant and diverse in Africa, they are found nearly worldwide  across temperate, subtropical, and tropical zones. The underground stems  may be rhizomes (e.g.. New World Iris species), bulbs (e.g., southwestern  European Iris species), or corms (e.g., Gladiolus).</p><p>Irish elk Any member of a genus ( Megaloceros) of extinct giant deer  commonly found as fossils in Pleistocene deposits (1.8 million-10,000  years ago) in Europe and Asia.

Irish is conventionally divided into three periods: Old Irish (600-c.  950), Middle Irish (c. 950-1200), and Modern Irish (from c. 1200).  Ogham writing predates Old Irish. Old and Middle Irish are the vehicles  of a rich literature of prose tales and verse. Classical Modern Irish was  the exclusive literary medium in Ireland and Scottish Gaeldom into mod�  em times (see Scottish Gaelic language). Literacy in Irish declined under  English rule; by 1800 it was all but an unwritten language. The deaths  and emigration resulting from the Irish Potato Famine and a massive shift  to English afterward drastically reduced the number of Irish-speakers.  Irish was revived as a literary language in the late 19th and early 20th  centuries, and with Irish independence (1921) it was made official.  Though it is a true community language only for a small number of people  on Ireland�s western coast in what are called Gaeltachts, hundreds of  thousands of Irish citizens and people of Irish descent have some com�  petence in Irish.</p><p>Irish literary renaissance Flowering of Irish literary talent in the  late 19th and early 20th century.

Other factors in the renaissance were the retelling of  ancient heroic legends in books such as Standish O�Grady�s History of  Ireland (1878, 1880) and Douglas Hyde�s A Literary History of Ireland  (1899), and the Gaelic League, formed in 1893 to revive the Irish lan�  guage and culture. It developed into a vigorous literary force centred on  William Butler Yeats; other important figures were Augusta Gregory, John  Millington Synge, and Sean O'Casey. See also Abbey Theatre.</p><p>Irish Potato Famine (1845-49) Famine that occurred in Ireland when  the potato crop failed in successive years. By the early 1840s almost half  the Irish population, particularly the rural poor, was depending almost  entirely on the potato for nourishment. A reliance on only one or two  high-yielding varieties made the crop vulnerable to disease, including the  late blight fungus, which ruined the crop. The British government pro�  vided minimal relief to the starving Irish, limited to loans and soup kitch�  ens. The famine was a watershed in Ireland�s demographic history: more  than a million people died from starvation or famine-related diseases, and  perhaps as many as 1.5 million emigrated to North America and Britain.  Population continued to decline thereafter, and by independence in 1921  the Irish population was barely half of the 8.4 million it had been before  the famine.</p><p>Irish Rebellion See Easter Rising</p><p>Irish Republican Army (IRA) Republican paramilitary organization,  founded in 1919, seeking the end of British rule in Northern Ireland and  the unification of the province with the republic of Ireland. The IRA used  armed force to achieve the same objectives as Sinn Fein, though the two  always operated independently. After the establishment of the Irish Free  State (1922), the IRA refused to accept a separate Northern Ireland, and  the violence continued. The IRA was declared illegal in 1931, and the  Irish legislature provided for internment without trial for its members. It  gained popular support in the 1960s when Roman Catholics in Northern  Ireland began a civil rights campaign against discrimination by the domi�  nant Protestant majority. In 1969 the IRA split into the Marxist Official  wing, which eschewed violence, and the Provisionals (Provos), Ulster  Catholics committed to the use of terror tactics against Ulster Protestants  and the British military, tactics that included the 1979 assassination of  Lord Mountbaiten and the killing of some 1,800 people by the early 1990s.  In 1994 the IRA declared a cease-fire, and its political representatives  were included in multiparty talks beginning in 1997. Negotiations pro�  duced the Good Friday Agreement (1998), in which the IRA agreed to  decommission (disarm). In the ensuing years the IRA destroyed some of  its weapons but resisted decommissioning its entire armoury, hampering  implementation of the peace agreement. In July 2005, however, the IRA  announced that it was ending its armed campaign and instead would pur�  sue only peaceful means to achieve its objectives.</p><p>Irish Sea Arm of the North Atlantic Ocean that separates Ireland from  Great Britain.

An industrial and cultural  centre, it is the seat of Irkutsk State University and the Siberian branch  of the Academy of Sciences.</p><p>iron Metallic chemical element, one of the transition elements, chemical  symbol Fe, atomic number 26. Iron is the most used and cheapest metal,  the second most abundant metal and fourth most abundant element in  Earth�s crust. It occurs rarely as a free metal, occasionally in natural alloys  (especially in meteorites), and in hundreds of minerals and ores, including  hematite, magnetite, limonite, and siderite. The human body contains about  one-sixth of an ounce (4.5 g) of iron, mostly in hemoglobin and its pre�  cursors; iron in the diet is essential to health. Iron is ferromagnetic (see  ferromagnetism) at ordinary temperatures and is the only metal that can be  tempered (see tempering). Its uses in steels of various types, as well as in  cast and wrought iron (collectively, �ferrous metals�), are numerous.  Alteration of its properties by impurities, especially carbon, is the basis  of steelmaking. Iron in compounds usually has valence 2 (ferrous) or 3  (ferric). Ferrous and ferric oxides (FeO and Fe 2 0 3 , respectively) are used  as pigments and the latter as jewelers� rouge. Rust is ferric oxide con�  taining water; ferric oxide is widely used as a magnetic recording mate�  rial in computer data-storage devices and magnetic tapes. Ferrous and  ferric sulfates and chlorides are all of industrial importance as mordants,  reducing agents, flocculating agents, or raw materials and in inks and fer�  tilizers.</p><p>Iron Act (1750) Measure by the British Parliament to restrict the Ameri�  can colonial iron industry. Pig iron and iron bar could be exported to  England duty-free to meet British needs. Further development of colonial  manufacturing to produce finished iron goods was prohibited, as was the  export of iron to other countries.</p><p>Iron Age Final technological and cultural stage in the Stone-Bronze-  Iron-Age sequence (or Three-Age System) in which iron largely replaced  bronze in implements and weapons. The start of the Iron Age varied geo�  graphically, beginning in the Middle East and southeastern Europe c. 1200  bc but in China not until c. 600 bc. Though the large-scale production of  iron implements brought new patterns of more permanent settlement, use  of iron for weapons put arms in the hands of the masses for the first time  and set off a series of large-scale movements and conquests that did not  end for 2,000 years and that changed the face of Europe and Asia. See  also Bronze Age.</p><p>Iron Curtain Political, military, and ideological barrier erected by the  Soviet Union after World War II to seal off itself and its dependent east�  ern European allies from open contact with the West and other noncom�  munist areas. Winston Churchill employed the term in a speech in Fulton,  Mo., U.S., about the division of Europe in 1946. The restrictions and the  rigidity of the Iron Curtain eased slightly after Joseph Stalin�s death in  1953, though the construction of the Berlin Wall in 1961 restored them.  The Iron Curtain largely ceased to exist in 1989-90 with the communists�  abandonment of one-party rule in eastern Europe.</p><p>iron-deficiency anemia Most common type of anemia, which may  develop in times of high iron loss and depletion of iron stores (e.g., rapid  growth, pregnancy, menstruation) or in settings of low dietary iron intake  or inefficient iron uptake (e.g., starvation, intestinal parasites, gastrec�  tomy). Much of the world�s population is iron-deficient to some degree.  Symptoms include low energy level and sometimes paleness, shortness of  breath, cold extremities, sore tongue, or dry skin. In advanced cases, red  blood cells are small, pale, and low in hemoglobin, blood iron levels are  reduced, and body iron stores are depleted.

Aside from  the languages of the Iroquois Confederacy (Mohawk, Oneida, Onondaga,  Cayuga, and Seneca, all originally spoken in New York, along with Tus-  carora, originally spoken in North Carolina) and Cherokee (originally  spoken in the southern Appalachians), the Iroquoian languages are extinct,  and with the exception of Huron and Wyandot, the extinct languages are  poorly documented. Iroquoian languages are remarkable for their gram�  matical intricacy. Much of a sentence�s semantic content is bound around  a verbal base, so a single very long word may constitute a fairly complex  utterance.</p><p>Iroquois \'ir-3-,kw6i\ Any of six North American members of the Iro�  quois Confederacy living mostly in southern Ontario and Quebec, Can.,  and in New York, Wisconsin, Ohio, and Oklahoma, U.S. The name Iro�  quois is a French derivation of Irinakhoiw, meaning �Rattlesnakes,� their  Algonquian enemy�s epithet. They call themselves Hodenosaunee, mean�  ing �People of the Longhouse.� The Iroquois were semi sedentary, prac�  ticed agriculture, palisaded their villages, and dwelled in longhouses that  lodged many families. Women worked the fields and, when they became  clan elders, helped determine the makeup of village councils. Men built  houses, hunted, fished, and made war. Iroquoian mythology was largely  preoccupied with supernatural aggression and cruelty, sorcery, torture, and  cannibalism. Their formal religion consisted of agricultural festivals. War�  fare was ingrained in Iroquois society, and war captives were often tor�  tured for days or made permanent slaves. All together the various Iroquois  tribes number about 70,000 members, with the Mohawk making up more  than half that figure.</p><p>Iroquois Confederacy or League of the Iroquois Confedera�  tion of five (later six) Indian tribes across upper New York that in the  17th�18th century played a strategic role in the struggle between the  French and British for supremacy in North America. The five original  nations were the Mohawk, Oneida, Onondaga, Cayuga, and Seneca; the  Tuscarora, a non-voting member, joined in 1722. According to tradition,  the confederacy was founded between 1570 and 1600 by Dekanawidah,  bom a Huron (see Wyandot), carrying out the earlier ideas of Hiawatha,  an Onondaga. Cemented mainly by their desire to stand together against  invasion, the tribes united in a common council composed of 50 sachems;  each original tribe had one vote, and unanimity was the rule. At first the  confederacy barely withstood attacks from the Huron and Mahican, but  by 1628 the Mohawk had defeated the Mahican and established them�  selves as the region�s dominant tribe. When the Iroquois destroyed the  Huron in 1648-50, they were attacked by the Huron�s French allies. Dur�  ing the American Revolution, the Oneida and Tuscarora sided with the  American colonists while the rest of the league, led by Joseph Brant, fought  for the British. The loyalist Iroquois were defeated in 1779 near Elmira,  N.Y., and the confederacy came to an end.</p><p>irrational number Among the real numbers, any of those that cannot  be represented as quotients of integers.

Chief ports  are Mandalay, Chauk, Prome (Pye), and Henzada.</p><p>irrigation Artificial supply of water to land, to maintain or increase  yields of food crops, a critical element of modern agriculture. Irrigation  can compensate for the naturally variable rate and volume of rain. Water  is pumped from natural ponds, lakes, streams, and wells; basin systems  and dams hold back larger streams and annual floods. Below the dam,  gates to concrete-lined canals are opened, conveying the water over the  land through gravity flow. More elaborate, expensive canals flow from  huge constructed reservoirs, which hold a year-round water supply. Today  portable irrigation systems of lightweight aluminum pipe are in wide use.  Drip irrigation, a newer method, uses narrow tubing to supply water  directly to the base of each plant.

He toured for 10 years with a stock company before  making his London debut in 1866. With his success in The Bells (1871), he  became a leading actor in H.L. Bateman�s company (1871-77). As actor-  manager of the Lyceum Theatre (from 1878), he made it London�s most  successful theatre. He formed a celebrated acting partnership with Ellen  Terry that lasted until the company dissolved in 1902. They were noted for  their Shakespearean roles, and their theatrical qualities complemented each  other: he the brooding introvert, she the spontaneous charmer.</p><p>Irving, John (Winslow) (b.

His best-selling The World According to Garp  (1978; film, 1982) is notable, like his other works, for its engaging story  line, colourful characterizations, macabre humour, and examination of  contemporary issues. Later novels  include The Hotel New Hampshire  (1981; film, 1984), The Cider House  Rules (1985; film, 1999), and A  Prayer for Owen Meany (1989).</p><p>Irving, Washington (b.

As court  composer to Emperor Maximilian I (from 1497), he was allowed to travel. He  had many students, including Ludwig Senfl, and his historical importance  in Germany is as the main disseminator of the progressive Northern style  there.

Isaiah�s call to prophesy came c. 742 bc, when  Assyria was beginning the westward expansion that later overran Israel.  A contemporary of Amos, Isaiah denounced economic and social injus�  tice among the Israelites and urged them to obey the Law or risk cancel�  lation of God�s covenant. He correctly predicted the destruction of  Samaria, or northern Israel, in 722 bc, and he declared the Assyrians to  be the instrument of God�s wrath.

The Arabic word islam means �submission��specifically,  submission to the will of the one God, called Allah in Arabic. Islam is a  strictly monotheistic religion, and its adherents, called Muslims, regard  the Prophet Muhammad as the last and most perfect of God�s messen�  gers, who include Adam, Abraham, Moses, Jesus, and others. The sacred  scripture of Islam is the Qur�an, which contains God�s revelations to  Muhammad. The sayings and deeds of the Prophet recounted in the sunna  are also an important source of belief and practice in Islam. The religious  obligations of all Muslims are summed up in the Five Pillars of Islam,  which include belief in God and his Prophet and obligations of prayer,  charity, pilgrimage, and fasting. The fundamental concept in Islam is the  SHARfAH, or Law, which embraces the total way of life commanded by  God. Observant Muslims pray five times a day and join in community  worship on Fridays at the mosque, where worship is led by an imam. Every  believer is required to make a pilgrimage to Mecca, the holiest city, at  least once in a lifetime, barring poverty or physical incapacity. The month  of Ramadan is set aside for fasting. Alcohol and pork are always forbid�  den, as are gambling, usury, fraud, slander, and the making of images. In  addition to celebrating the breaking of the fast of Ramadan, Muslims cel�  ebrate Muhammad�s birthday (see mawlid) and his ascension into heaven  (see mi'raj). The Td al-Adha festival inaugurates the season of pilgrimage  to Mecca. Muslims are enjoined to defend Islam against unbelievers  through jihad. Divisions occurred early in Islam, brought about by dis�  putes over the succession to the caliphate (see caliph). About 90% of Mus�  lims belong to the Sunnite branch. The ShUtes broke away in the 7th  century and later gave rise to other sects, including the IsmATus. Another  significant element in Islam is the mysticism known as Sufism. Since the  19th century the concept of the Islamic community has inspired Muslim  peoples to cast off Western colonial rule, and in the late 20th century fun�  damentalist movements (see Islamic fundamentalism) threatened or toppled  a number of secular Middle Eastern governments. In the early 21st cen�  tury, there were more than 1.2 billion Muslims in the world.</p><p>Islam, Nation of See Nation of Islam</p><p>Islam, Pillars of Five duties incumbent on every Muslim.

He was executed following a public trial.</p><p>Islamic arts Visual, literary, and performing arts of the populations that  adopted Islam from the 7th century. Islamic visual arts are decorative,  colourful, and, in religious art, nonrepresentational; the characteristic  Islamic decoration is the arabesque. From ad 750 to the mid 11th century,  ceramics, glass, metalwork, textiles, illuminated manuscripts, and wood�  work flourished; lustred glass became the greatest Islamic contribution to  ceramics. Manuscript illumination became an important and greatly  respected art, and miniature painting flourished in Iran after the Mongol  invasions (1220-60). Calligraphy, an essential aspect of written Arabic,  developed in manuscripts and architectural decoration. Islamic architec�  ture finds its highest expression in the mosque and related religious build�  ings. Early Islamic religious architecture drew upon Christian  architectural features such as domes, columnar arches, and mosaics, but  also included large courtyards for congregational prayer. Religious archi�  tecture came into its own in the period of the caliphates with the creation  of the hypostyle mosque in Iraq and Egypt. Islamic literature is written  in four main languages: Arabic, Persian, Turkish, and Urdu. Arabic is of  overwhelming importance as the language of the revelation of Islam and  of the Qur�an. The Persians used the genres, forms, and rules of Arabic  poetry in their own language but elaborated on them. They also devel�  oped a new genre, the masnavl, composed of a series of rhyming cou�  plets, which they employed for epic poetry. Persian literature in turn  influenced both Urdu and Turkish literature, especially with regard to  vocabulary and metres. In the realm of popular literature, the best-known  work is The Arabian Nights� Entertainment, a rich collection of fairy tales  from different parts of the Muslim world. Islamic music is monophonic,  devoid of harmony, and characterized by distinctive systems of rhythms  and melodies, extensive ornamentation of the single melodic line, and  virtuoso improvisation. It is usually performed by a small ensemble�a  singer and several instrumentalists who alternate solo vocal and instru�  mental passages. While the theatre has not flourished as a major art under  Islam�indeed, conservative Muslims have consistently disapproved of  the theatre�there are traditions of folk dance, dance as an entertainment  spectacle, and dance as an art form in most Islamic countries. One note�  worthy form of devotional dance is that of the dervish.

Their development can be traced to the  caste system of Hinduism and the tendency of Muslim converts from  Hinduism to maintain social differences. The highest status is reserved  for Muslim Arab immigrants, called ashraf. This level is itself divided  into subgroups. The highest subgroup claims descent from Muhammad  through his daughter, Fatima. The non-ashraf Muslim castes consist of  three levels: converts from high Hindu castes, artisan castes, and the  UNTOUCHABLES.</p><p>Islamic law See Sharia</p><p>Islamic philosophy See Arabic philosophy</p><p>Islamic Resistance Movement See Hamas</p><p>Islamic Salvation Front French Front Islamique du Salut  (FIS) Algerian Islamist political party.

Bom into a Shl'ite family with close ties to the Sunnite Sufi tra�  dition, he became head of a Shl'ite military force, the Kizilbash, at age  14. He captured Tabriz in 1501 and proclaimed himself shah of Iran,  bringing the whole country and portions of modern-day Iraq under his  control. In 1510 his troops defeated the Sunnite Uzbeks. His proclama�  tion of Shl'ism as the official creed prompted the staunchly Sunnite sul�  tan of the Ottoman Empire to order an invasion of Iran in 1514. Isma'Il lost  the Battle of Chaldiran, but mutiny among the Ottoman troops forced their  withdrawal.

After an education in Paris and dip�  lomatic missions in other parts of Europe, he was appointed viceroy and  became involved with work on the Suez Canal (1859-69). His plan to  unify the Nile valley by creating a new southern Egyptian province in the  Sudan failed. The sultan dismissed him because of his fiscal mismanage�  ment; the enormous debt he brought on the country led the British to  occupy Egypt in 1882.</p><p>IsmaTl? \,is-ma-'e-le\ Member of a sect of the ShCite branch of Islam. It  came into existence after the death of the sixth imam, Ja'far ibn Muhammad,  in 765. His son Isma'Il was accepted as successor only by a minority, who  became known as Isma'IlItes. Their doctrine, formulated in the late 8th  and early 9th century, made a distinction between ordinary Muslim believ�  ers and the elect, who shared a secret wisdom. The Qaramitah subsect  was popular in Iraq, Yemen, and Bahrain in the 9th�11th centuries, and  the Fatimid subsect conquered Egypt in 969 and established the Fajimid  dynasty. A subgroup of the Fatimids was the Nizarls, who gained control  of fortresses in Iran and Syria in the late 11th century and were known  as Assassins. The major Nizarl line survived into modem times under the  leadership of the Aga Khan, moving from Iran to India in 1840. The Druze  separated from the Isma'IlIs early in the 11th century and formed a closed  society of their own.</p><p>Ismay Viz-ma\ (of Wormington), Hastings Lionel Ismay,  Baron (b.

Isolationism has been a recurrent  theme in U.S. history. It was given expression in the Farewell Address of  Pres. George Washington and in the early 19th-century Monroe Doctrine.  The term is most often applied to the political atmosphere in the U.S. in  the 1930s. The failure of Pres. Woodrow Wilson�s internationalism, lib�  eral opposition to war as an instrument of policy, and the rigours of the  Great Depression were among the reasons for Americans� reluctance to  concern themselves with the growth of fascism in Europe. The Johnson  Act (1934) and the Neutrality acts (1935) effectively prevented economic  or military aid to any country involved in the European disputes that were  to escalate into World War II. U.S. isolationism encouraged the British in  their policy of appeasement and contributed to French paralysis in the face  of the growing threat posed by Nazi Germany.

It is used in medicine and biochemical research  and as a nutritional supplement.</p><p>isomer Vl-so-morX One of two or more substances with identical molecu�  lar formulas but different configurations, differing only in the arrangement  of their component atoms. It usually refers to stereoisomers (rather than  constitutional isomers or tautomers; see isomerism, tautomerism), of which  there are two types. Optical isomers, or enantiomers (see optical activity),  occur in mirror-image pairs. Geometric isomers are often the result of  rigidity in the molecular structure; in organic compounds, this is usually  due to a double bond (see bonding) or a ring structure. In the case of a  double bond between two carbon atoms, if each has two other groups  bonded to it and all are rigidly in the same plane, the corresponding groups  can be on the same side (cis) of the C=C bond or across the C=C bond  (trans) from each other. An analogous distinction can be made for ring  structures that are all in a plane, between isomers whose substituent  groups are on the same side and isomers whose substituent groups are on  both sides of the plane. Diastereomers that are not enantiomers also fall  into this category. Most cis-trans isomers are organic compounds.</p><p>isomerism U-'sa-mo-.ri-zonA Existence of sets of two or more sub�  stances with identical molecular formulas (see chemical formula) but dif�  ferent configurations and hence different properties. Jons Jacob Berzelius  was the first to recognize and name it (1830). In constitutional (structural)  isomerism, the molecular formula and molecular weight of the substances  are the same, but their bonding differs. For example, C 2 H 6 0 is the molecu�  lar formula for both ethanol (CH 3 CH 2 OH) and methyl ether (CH 3 OCH 3 ).  Constitutional isomers that can be readily converted from one to another</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Isonzo &#x25BA; Israel I 965</p><p>are called tautomers (see tautomerism).

The Isonzo River, running just inside Austria, is flanked by rugged peaks  that the Austrians had fortified before Italy�s entry into the war in 1915.  Luigi Cadoma (1850-1928) led all the attacks against Austria, but the Ital�  ians could not penetrate the formidable natural barriers. Finally they  struck with 51 divisions and dislodged the Austrians, but the Germans sent  reinforcements and took the offensive, ending in the Battle of Caporetto.</p><p>isoprenoid Vj-so-'pre-.noidV or terpene Class of organic compounds  made up of two or more structural units derived from isoprene. Isoprene  is a five-carbon hydrocarbon with a branched-chain structure, two double  bonds (see bonding), and the molecular formula C 5 H 8 . In isoprenoids,  isoprene units (with one or neither of their double bonds) are linked into  larger molecules having from two to thousands of five-carbon units that  can take the form of both linear structures and rings. Many of these mol�  ecules play a wide variety of roles in plant and animal physiological pro�  cesses and as intermediates in the biological synthesis of other important  molecules. They contribute greatly to the flavours and fragrances of essen�  tial oils and other plant-derived substances. Geraniol (a contributor to rose  perfumes; from geranium oil), menthol (from peppermint oil), citral (from  lemongrass oil), limonene (from lemon and orange oils), pinene (from  turpentine), and camphor each have two isoprene units. Examples with  more units include phytol, a precursor of chlorophyll; squalene, the pre�  cursor of cholesterol and other steroids; lycopene, the red pigment in  tomatoes and an important phytochemical; and carotene, the pigment in  carrots and a precursor of vitamin A. Natural rubber and the related gutta�  percha are polyisoprenes comprising many thousands of isoprene units.</p><p>isospin Vl-sd-,spin\ or isobaric spin or isotopic spin Property  characteristic of families of related subatomic particles differing mainly in  the values of their electric charge. The families are known as isospin mul-  tiplets.

They are considered different versions of the same object,  called a nucleon.

In this theory, a mass above sea level is supported below sea level,  so high mountains must be regions where the crust is very thick, with  deep roots extending into the mantle. This is analogous to an iceberg  floating on water, in which the greater part of the iceberg is under water.</p><p>isotope Vl-s3-,top\ One of two or more species of atoms of a chemical  element having nuclei with the same number of protons but different num�  bers of neutrons. They have the same atomic number and hence nearly  identical chemical behaviour but different atomic MASSes. Most elements  found in nature are mixtures of several isotopes; tin, for example, has 10  isotopes. In most cases, only stable isotopes of elements are found in  nature. The radioactive forms break down spontaneously into different  elements (see radioactivity). Isotopes of all elements heavier than bismuth  are radioactive; some occur naturally because they have long half-lives.</p><p>Isozaki \,e-so-'za-ke\ A rata (b.

Its major drainage system is the interior basin formed by the Jor�  dan River; Lake Tiberias (Sea of Galilee) provides water to much of the  country�s agricultural land. Israel has a mixed economy based largely on  services and manufacturing; exports include machinery and electronics,  diamonds, chemicals, citrus fruits, vegetables, and textiles. Its population  is nine-tenths urban and is concentrated largely in the Mediterranean  coastal plain and around Jerusalem. It is a republic with one legislative  house, the Knesset; its chief of state is the president, and the head of gov�  ernment is the prime minister. The record of human habitation in Israel  (see Palestine) dates to the Paleolithic Period. Efforts by Jews to establish  a national state there began in the late 19th century. Britain supported  Zionism and in 1923 assumed political responsibility for what was then  called Palestine. Migration of Jews to Palestine, which increased during  the period of Nazi persecution, led to deteriorating relations with Arabs.  In 1947 the UN voted to partition the region into separate Jewish and Arab  states. The State of Israel was proclaimed in 1948, and Egypt, Transjor�  dan (later Jordan), Syria, Lebanon, and Iraq immediately declared war on  it. Israel won that war (see Arab-Israeli wars) as well as the 1967 Six-Day  War, in which it occupied the West Bank, Gaza Strip, Golan Heights, and  east Jerusalem. (Subsequent claims of Jerusalem as Israel�s capital have  not received wide international recognition.) Another war with its Arab  neighbours followed in 1973, but the Camp David Accords led to a peace  treaty between Israel and Egypt in 1979. Israel invaded Lebanon in 1982  to expel the Palestine Liberation Organization (PLO) from that country, and  in late 1987 an uprising broke out among Palestinians of the occupied ter�  ritories of the West Bank and Gaza Strip (see intifadah). Peace negotia�  tions between Israel and the Arab states and Palestinians began in 1991.  Israel and the PLO agreed in 1993 to a five-year plan to extend self-  government to the Palestinians of the occupied territories. Israel signed a  peace treaty with Jordan in 1994. Israeli soldiers and a Lebanese militia,  Hezbollah, clashed throughout the 1990s. Israeli troops withdrew from  Lebanon in 2000, and negotiations between Israel and the Palestinians  broke down amid violence that claimed hundreds of lives. In an effort to  stem the fighting, Israel in 2005 withdrew its soldiers and settlers from  parts of the West Bank and from all of the Gaza Strip, which came under  Palestinian control.</p><p>Israel, tribes of In the Bible, the 12 clans of the ancient Hebrew people,  which were named for the sons of Jacob (Reuben, Simeon, Levi, Judah,  Issachar, Zebulun, Joseph, Benjamin, Gad, Asher, Dan, and Naphtali) and  his wives, Leah and Rachel, and concubines, Bilhah and Zilpah.

In Israel�s later history, the tribes of Judah and Benjamin formed a south�  ern kingdom called Judah with its capital at Jerusalem, while the 10 north�  ern tribes formed the kingdom of Israel. After being conquered by Assyria  in 721 bc, the northern tribes were exiled from the kingdom and were  assimilated by other peoples. Disappearing from history, they became  known as the 10 lost tribes of Israel and remained part of Jewish folklore  and eschatological beliefs.

The  ancient people of Israel created the law of the Torah and the Mishna (the  latter was later incorporated into the Talmud). Contemporary Israeli law  reflects a dual legal heritage: it is based on historic Jewish law and the  laws of countries in which the Jews had for generations been living. It is  derived from Ottoman and British legislation and precedents, religious  court opinion, and Israeli parliamentary enactments. Courts are composed  of professional judges only; juries are not used.

Byzantium was  founded as a Greek colony in the 8th century bc. Passing to the Persian  Achaemenian dynasty in 512 bc and then to Alexander the Great, it became  a free city under the Romans in the 1st century ad. The emperor Con�  stantine I made the city the seat of the Eastern Roman Empire in 330, later  naming it Constantinople. It remained the capital of the subsequent Byz�  antine Empire after the fall of Rome in the late 5th century. In the 6th-13th  centuries it was frequently besieged by Persians, Arabs, Bulgars, and  Russians. It was captured by the Fourth Crusade (1203) and turned over  to Latin Christian rule. It was returned to Byzantine rule in 1261. In 1453  it was captured by the Ottoman Empire and made the Ottoman capital.  When the Republic of Turkey was founded in 1923, the capital was moved  to Ankara, and Constantinople was officially renamed Istanbul in 1930.

After  Italy�s surrender in World War II, former party leaders, along with Catholic  organizations, founded the Christian Democratic Party, which held power  in Italy (usually in coalition with other parties) for most of the postwar era.  In 1992-93 it was rocked by the involvement of some of its leading mem�  bers in financial scandals and political corruption. In 1993 the struggling  party reverted to its original name, but in the 1994 parliamentary elections  it fell from power and was reduced to a minor party.

In 1998 the Italian Socialists merged with two other left�  ist parties to form the Italian Democratic Socialists. In the early 21st cen�  tury, the party contested elections as part of the Olive Tree coalition.</p><p>Italian Somaliland Former Italian colony, eastern Africa. It extended  south from Cape Asir to the boundary of Kenya, occupying an area of  178,218 sq mi (461,585 sq km). Italy obtained control of it in 1889 and  it was incorporated as a state in Italian East Africa in 1936. Britain invaded  in 1941 and retained control until it became a UN trust territory under  Italian administration in 1950. In 1960 it was united with British Somali�  land to form the independent Republic of Somalia.</p><p>Italian Wars (1494-1559) Series of violent wars for control of Italy.  Fought largely by France and Spain but involving much of Europe, they  resulted in the Spanish Habsburgs dominating Italy and shifted power  from Italy to northwestern Europe and its Atlantic world. The wars began  with the invasion of Italy by the French king Charles VIII in 1494. He took  Naples, but an alliance between Maximilian I, Spain, and the pope drove  him out of Italy. In 1499 Louis XII invaded Italy and took Milan, Genoa,  and Naples, but he was driven out of Naples in 1503 by Spain under Fer�  dinand V. Pope Julius II organized the League of Cambrai (1508) to attack  Venice, then organized the Holy League (1511) to drive Louis out of  Milan. In 1515 Francis I was victorious at the battle of Marignano, and in  1516 a peace was concluded by which France held onto Milan and Spain  kept Naples. Fighting began in 1521 between Emperor Charles V and  Francis I. Francis was captured and forced to sign the Treaty of Madrid  (1526), by which he renounced all claims in Italy, but, once freed, he  repudiated the treaty and formed a new alliance with Henry VIII of  England, Pope Clement VII, Venice, and Florence. Charles sacked Rome  in 1527 and forced the pope to come to terms, and Francis gave up all  claims to Italy in the Treaty of Cambrai (1529). By the Treaty of Cateau-  Cambresis (1559), the wars finally ended.</p><p>Italic \i-'ta-lik\ languages Indo-European languages spoken in the  Apennine Peninsula (Italy) during the 1st millennium bc, after which only  Latin survived. Traditionally thought to be a subfamily of related languages,  these languages include Latin, Faliscan, Osco-Umbrian, South Picene, and  Venetic. Latin, the language of Latium and Rome, began to emerge as the  predominant language as early as the 3rd century bc. By ad 100 it had  replaced all dialects (except Greek) between Sicily and the Alps. Until  then, Oscan dialects were most widely spoken; Umbrian, in central Italy,  was closely related to Oscan. Venetic was spoken in the region of Venice.  These languages were written in various alphabets, including the Greek and  Latin alphabets and modified versions of the Etruscan.</p><p>Italic War See Social War</p><p>Italo-Turkish War (1911-12) War undertaken by Italy to gain colo�  nies in North Africa by conquering the Turkish provinces of Tripolitana  and Cyrenaica (modern Libya).

Population (2005 est.):  57,989,000. Capital: Rome. The people are  overwhelmingly Italian. Language: Italian  (official). Religion: Christianity (predomi�  nantly Roman Catholic). Currency: euro.  More than three-fourths of Italy is mountainous or highland country. The  Alps stretch from east to west along Italy�s northern boundary, and the  Apennines stretch southward the length of the peninsula. Most of the coun�  try�s lowlands lie in the valley of its major river, the Po. Three tectonic  plates converge in southern Italy and Sicily, creating intense geologic  activity; southern Italy�s four active volcanoes include Mount Vesuvius and  Mount Etna. The economy is based largely on services and manufacturing;  exports include machinery and transport equipment, chemicals, textiles,  clothing and shoes, and food products (olive oil, wine, fruit, and tomatoes).  Italy is a republic with two legislative houses. The chief of state is the presi�  dent, and the head of government is the prime minister. Italy has been  inhabited since Paleolithic times. The Etruscan civilization arose in the 9th  century bc and was overthrown by the Romans in the 4th-3rd centuries bc  (see Roman Republic and Empire). Barbarian invasions of the 4th-5th centu�  ries ad destroyed the Western Roman Empire. Italy�s political fragmenta�  tion lasted for centuries but did not diminish its impact on European  culture, notably during the Renaissance. From the 15th to the 18th century,  Italian lands were ruled by France, the Holy Roman Empire, Spain, and Aus�  tria. When Napoleonic rule ended in 1815, Italy was again a grouping of  independent states. The Risorgimento successfully united most of Italy,  including Sicily and Sardinia by 1861, and the unification of peninsular  Italy was completed by 1870. Italy joined the Allies during World War I,  but social unrest in the 1920s brought to power the Fascist movement of  Benito Mussolini, and Italy allied itself with Nazi Germany in World War II.  Defeated by the Allies in 1943, Italy proclaimed itself a republic in 1946.  It was a charter member of NATO (1949) and of the European Community  (now embedded in the European Union). It completed the process of setting  up regional legislatures with limited autonomy in 1970s. After World War  II it experienced rapid changes of government but remained socially stable.</p><p>Itami \e-'ta-me\, Juzo orig. Yoshihiro Ikeuchi (b. May 15, 1933,  Kyoto, Japan�d.

Oct. 14, 1841, Suo province,  Japan�d. Oct. 26, 1909, Harbin, Manchuria, China) Japanese statesman,  prime minister, and writer of the Meiji Constitution. He played a minor  role in the Meiji_ Restoration, through which he came in contact with Kido  Takayoshi and Okubo Toshimichi. When Okubo was assassinated in 1878,  Ito succeeded him as home minister. He persuaded the government to  adopt a constitution, then traveled abroad to research constitutions. In  1889 the emperor promulgated the resultant document. Later, as prime  minister, Ito negotiated an end to extraterritoriality with Britain; other  Western nations followed suit, signaling that the West was beginning to  treat Japan as an equal. Frustrated with the ability of the political parties  to impede passage of government programs in the Diet, in 1900 Ito  founded his own party, the Rikken SeiyOkai. This foray cost him control of  the genro (elder statesmen) but made cooperation between high-ranking  bureaucrats and party politicians acceptable. In 1906 Ito became resident  general in Korea; he was assassinated in 1909 by a Korean nationalist.</p><p>Ito Jinsai Ve-to-'jen-.sA (b. Aug. 30, 1627, Kyoto, Japan�d.

An army officer when  the independence movement emerged in 1810, he fought for the royalists,  but in 1820, in reaction to a liberal coup in Spain, the conservatives did  an about-face and advocated immediate independence. Iturbide joined  forces with the insurgents and won Mexico�s independence in 1821. In  1822 he crowned himself emperor, but his arbitrary and extravagant ways  cost him support. His abdication in 1823 did not save him from execu�  tion.

He took the throne after overthrowing and blinding his cousin  Boril. A good soldier and administrator, Ivan restored order, controlled  the boyars, and acquired much of Albania, Serbia, Macedonia, and Epi�  rus (1230). He forged alliances through the marriages of his daughters,  but a treaty to make him regent of the Latin empire was repudiated by  Latins fearful of Bulgaria�s growing power, and he afterward separated  the Bulgarian church from Rome.</p><p>Ivan Vi-v9n\ III known as Ivan the Great (b.

Determined to enlarge the territory he inherited from his father,  Ivan led successful military campaigns against the Tatars in the south  (1458) and east (1467-69). He subdued Novgorod (1478) and gained  control of most of the remainder of Great Russia by 1485. He also  renounced Moscow�s subjection to the khan of the Golden Horde (1480)  and won a final victory over the khan�s sons in 1502. Stripping the boyars  of much of their authority, he laid the administrative foundations of a cen�  tralized Russian state.

Crowned tsar in 1547  after a long regency (1533-46), he  embarked on wide-ranging reforms,  including a centralized administra�  tion, church councils that system�  atized the church�s affairs, and the  first national assembly (1549). He  also instituted reforms to limit the  powers of the boyars. After conquer�  ing Kazan (1552) and Astrakhan  (1556), he engaged in an unsuccess�  ful war to control Livonia, fighting  against Sweden and Poland (1558�</p><p>83). After the defeat and the sus�  pected treason of several Russian  boyars, Ivan formed an oprichnina, a territory separate from the rest of  the state and under his personal control. With a large bodyguard, he with�  drew into his own entourage and left Russia�s management to others. At  the same time, he instituted a reign of terror, executing thousands of  boyars and ravaging the city of Novgorod.

He left college to hitchhike around  the U.S., collecting songs from hoboes and drifters. Soon after his post�  war concert debut in New York City, he was hailed by Carl Sandburg as  �the mightiest ballad singer of this or any other century.� He recorded  more than 100 albums and had hits with �I Know an Old Lady (Who  Swallowed a Fly),� �The Blue Tail Fly,� �Big Rock Candy Mountain,�  �Frosty the Snowman,� and �A Little Bitty Tear.� He appeared in many  films�including East of Eden (1955), Desire Under the Elms (1958), Cat  on a Hot Tin Roof( 1958), and The Big Country (1958, Academy Award)�  and on Broadway.</p><p>Ives, Charles E(dward) (b.

Ives claimed to be the  product of training by his father, George, a highly imaginative former  Union Army bandmaster. He received a solid classical grounding and  began composing and performing at an early age. At Yale University he  studied with the academic composer Horatio Parker (1863-1919) and  composed his first symphony. Under the influence of Transcendentalism,  he decided to forgo a music career, and in 1907 he founded a successful  insurance firm. With music as a �sideline,� he felt free to pursue his  unusual interests, though he suffered from his amateur status and a lack  of intelligent critiques. A heart attack in 1918 curtailed all activities, and  he stopped composing c. 1926. His music is tonal despite much disso�  nance, atmospheric, and nostalgic, and it runs the gamut from sentimen�  tal or quirkily humorous songs to exciting tone poems ( The Fourth of July,  1913) and weighty meditations ( Concord Sonata, 1915). He apparently  made many remarkable tonal innovations, though questions have been  raised about whether he later predated his works to give a misleading  impression. His music was rediscovered late in his life; the third of his  four symphonies won a Pulitzer Prize in 1947.</p><p>IVF See IN VITRO FERTILIZATION</p><p>ivory Hard white substance, a variety of dentin, that makes up the tusks  of such animals as elephants, walruses, and preserved mammoths.

Most ivory used  commercially once came from Africa; sales of ivory declined in the 20th  century as the populations of African elephants shrank, and worldwide  concern about endangered elephant populations have led to bans on the  export and import of ivory.

In  2005, however, researchers  announced that it had been sighted in  eastern Arkansas. The species�  decline coincided with the logging of  virgin forest, where it subsisted on  deadwood insects. A subspecies, the  Cuban ivory-billed woodpecker, is  also believed to be extinct. A related  species, the imperial woodpecker of  Mexico, is critically endangered.

It has flourished since prehistoric  times. Most Stone Age carvings have  been found in southern France, in the  forms of small nude female figures  and animals. A masterpiece of early  Egyptian carving is an ivory statuette  of Khufu, builder of the Great Pyra�  mid. In China ivory carvings have  been found in the tombs of the Shang  dynasty (18th�12th century bc). The  major artistic use of ivory in Japan  was for netsukes, toggles used as fas�  teners on men�s clothing.

Most of its  present buildings were constructed in the 19th century.</p><p>Izvestiya \iz-'ves-te-o\ formerly in full Izvestiya Sovetov Depu-  tatov Trudyashchikhsya SSSR (Russian: �News of the Councils  of Working People�s Deputies of the U.S.S.R.�) Russian daily newspaper  published in Moscow, the official national publication of the Soviet gov�  ernment until 1991. Founded in 1917, it grew rapidly in circulation.  Restrictions during World War II and under Joseph Stalin slowed its  growth, but it was transformed into a lively, readable daily under the edi�  torship of Alexei Adzhubei, Nikita Khrushchev�s son-in-law, while remain�  ing an instrument of the state. Following the Soviet Union�s breakup, it  became an independent, employee-owned publication whose liberal edi�  torial policy often put it at odds with both unreconstructed communists  and Russian nationalists.</p><p>Izvolsky \iz-'v6l-ske\, Aleksandr (Petrovich), Count (b. March  18, 1856, Moscow, Russia�d. Aug. 16, 1919, Paris, France) Russian dip�  lomat. He became minister of foreign affairs in 1906. In 1908 he secured  Austria�s support for the right of Russian warships to use the Dardanelles  strait in return for his reluctant support of Austria�s annexation of Bosnia  and Herzegovina. While Austria succeeded in its annexation (see Bosnian  crisis), Russia failed to gain access to the Dardanelles; Izvolsky�s respon�  sibility for Russia�s diplomatic defeat increased tensions with Austria-  Hungary prior to World War I. Dismissed in 1910, he served as  ambassador to France until 1917.</p><p>U.S. Marines raising the American flag  over Mount Suribachi, Iwo Jima, in  February 1945.</p><p>JOE ROSENTHAL-AP/WIDE WORLD</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Jabal al-Shaykh &#x25BA; Jackson I 971</p><p>Jabal al-Shaykh See Mount Hermon</p><p>Jabal River or Bahr al-Jabal \,bar-el-'je-bel\ River, south-central  Sudan.

Jacarandas are grown widely in warm parts of the world  and in greenhouses for their showy blue or violet flowers and attractive,  oppositely paired, compound leaves. The genus includes about 50 spe�  cies native to Central and South America and the West Indies. The name  is also applied to several tree species of the genera Machaerium and  Dcilbergia in the pea family (see legume), the sources of commercial  rosewood.</p><p>jack In practical mechanics, portable hand-operated device  for raising heavy weights through short distances, exert�  ing great pressures, or holding assembled work firmly in  position.

Though body size and shape vary greatly, many species have small scales  that create a smooth appearance, a laterally compressed body, rows of  large spiky scales along the side near the tail fin, and a deeply forked tail.  Many have a bluish green, silvery, or yellowish sheen. Jacks are impor�  tant commercially and are favoured sport fishes. See also amberjack.</p><p>jack-in-the-pulpit North American plant ( Arisaema triphyllum) of the  arum family, noted for the unusual shape of its flower. One of the best-  known perennial wildflowers of late spring in the eastern U.S. and  Canada, it grows in wet woodlands and thickets from Nova Scotia to  Minnesota and south to Florida and Texas. Three-part leaves on each of  two long stalks overshadow the flower, which consists of a conspicuous  green- and purple-striped structure called a spathe (�pulpit�) that rises on  a separate stalk. The spathe curves in a hood over a club-shaped spadix  (�jack�) that, at its base, bears minute flowers. In late summer the plant  produces a cluster of brilliant red berries that are poisonous to humans  but are eaten by many wild animals.</p><p>Jack the Ripper Pseudonymous murderer of at least five women, all  prostitutes, in or near London�s Whitechapel district, from Aug. 7 to Nov.  10, 1888. The throat of each victim was cut, and usually the body was  mutilated in a manner indicating the murderer had considerable knowl�  edge of human anatomy. Authorities received a series of taunting notes  from a person calling himself Jack the Ripper and purporting to be the  murderer. Although strenuous efforts were made to identify and trap the  killer, he remained unknown. The unsolved case retained its hold on the  popular imagination, becoming the subject of several motion pictures and  more than 100 books, as well as a macabre tourist industry in London.</p><p>jackal Any of three canine species of the genus Canis. They inhabit open  country and live alone, in pairs, or in packs. They hunt at night, feeding  on small animals, plant material, or carrion. A pack can bring down larger  prey.

Settled in  1792 by Louis Le Fleur, a French Canadian trader, it was a trading post  called Le Fleur�s Bluff until settlers began arriving in 1820. It was made  the state capital in 1822 and was named for Andrew Jackson. During the  American Civil War it was burned by Union forces (1863). The state�s  largest city, it is a railroad and distribution centre. It is the seat of Jack-  son State University (1877) and other educational institutions.</p><p>Jackson, A(lexander) Y(oung) (b. Oct. 3, 1882, Montreal, Que.,  Can.�d. April 5, 1974, Kleinburg, Ont.) Canadian landscape painter. He  traveled to every region of Canada, including the Arctic; from 1921 on,  he returned every spring to a favourite spot on the St. Lawrence River,  where he produced sketches that he later executed in paint. Over a long  career he became a leading artistic figure in his country. His easy style,  featuring rolling rhythms and rich, full colour, exerted a strong influence  on Canadian landscape painting.</p><p>Jackson, Andrew (b. March 15,1767, Waxhaws region, S.C.�d. June  8, 1845, the Hermitage, near Nash�  ville, Tenn., U.S.) Seventh president  of the U.S. (1829-37). He fought  briefly in the American Revolution  near his frontier home, where his  family was killed in the conflict. In  1788 he was appointed prosecuting  attorney for western North Carolina.</p><p>When the region became the state of  Tennessee, he was elected to the U.S.</p><p>House of Representatives (1796-97)  and the Senate (1797-98). He served  on the state supreme court (1798�</p><p>1804) and in 1802 was elected major  general of the Tennessee militia.</p><p>When the War of 1812 began, he  offered the U.S. the services of his  50,000-man volunteer militia.

A decisive victory at the Battle of New Orleans made him a national  hero; he was dubbed �Old Hickory� by the press. After the U.S. acquired  Florida, Jackson was named governor of the territory (1821). One of four  candidates in the 1824 presidential election, he won an electoral-vote plu�  rality, but the House of Representative instead selected John Quincy Adams  as president. Jackson�s victory over Adams in the 1828 presidential elec�  tion is commonly regarded as a turning point in U.S. history. Jackson was  the first president from west of the Appalachian Mountains, the first to be  born in poverty, and the first to be elected through a direct appeal to the  mass of voters rather than through the support of a recognized political  organization. The era of his presidency has come to be known as �Jackso�  nian Democracy.� Upon taking office he replaced many federal officials  with his political supporters, a practice that became known as the spoils sys�  tem. His administration acquiesced in the illegal seizure of Cherokee land in  Georgia and then forcibly expelled the Indians who refused to leave (see  Trail of Tears). When South Carolina claimed a right to nullify a federally  imposed tariff, Jackson asked for and received Congressional authority to  use the military to enforce federal laws in the state (see nullification). His  reelection in 1832 was partially the result of his controversial veto of a bill  to recharter the Bank of the United States, which was unpopular with many  of his supporters (see Bank War). The intensity of the political struggles  during his tenure led to the strengthening of the Democratic Party and to the  further development of the two-party system.</p><p>Jackson, Charles Thomas (b. June 21, 1805, Plymouth, Mass.,  U.S.�d. Aug. 28, 1880, Somerville, Mass.) U.S. physician, chemist,  geologist, and mineralogist. He graduated from Harvard Medical School  in 1829. Known for his contentiousness and litigiousness, he took credit  for the first demonstration of surgical anesthesia with ether by a dental  surgeon he had advised on it, and he claimed to have told Samuel F.B.  Morse the basic principles of the telegraph. He worked many years as a  geologist for the U.S. Geological Survey.</p><p>Jackson, Glenda (b. May 9, 1936, Birkenhead, Cheshire, Eng.)

She became known for her tense portrayals of complex women,  gaining international acclaim in the film Women in Love (1969, Academy  Award) and later successes such as Sunday Bloody Sunday (1971), A  Touch of Class (1973, Academy Award), and the television series Eliza�  beth R. Her screen career continued until 1992, when she won a seat in  the House of Commons.</p><p>Jackson, Jesse (Louis) orig. Jesse Louis Burns (b.

In 1965 he went to  Selma, Ala., to march with Martin  Luther King, Jr., and began working  for King�s Southern Christian Leader�  ship Conference (SCLC). In 1966 he  helped found the Chicago branch of  Operation Breadbasket, the SCLC�s  economic arm; he was its national  director from 1967 to 1971.</p><p>Ordained a Baptist minister in 1968,  he founded Operation PUSH (People  United to Save Humanity) in 1971.</p><p>In 1983 he led a voter-registration  drive in Chicago that helped elect the  city�s first African American mayor,</p><p>Harold Washington. In 1984 and  1988 Jackson entered the Demo�  cratic presidential primary, becom�  ing the first African American man to  make a serious bid for the U.S. presidency; he received 6.7 million votes  in 1988. In 1989 he moved to Washington, D.C. and was elected the city�s  unpaid �statehood senator� to lobby Congress for statehood. From the late  1970s Jackson gained wide attention through his attempts to mediate in  various international disputes, including in the Middle East. In the late  1990s he faced allegations of financial misconduct, and in 2001 he admit�  ted fathering a child out of wedlock.</p><p>Jackson, Joe in full Joseph Jefferson Jackson known as Sho�  eless Joe Jackson (b.

An outstand�  ing hitter, his career batting average of .356 is the third-highest (after Ty  Cobb and Rogers Hornsby) in baseball history. Jackson was involved in  the 1919 Black Sox scandal; though acquitted in 1921, he was banned from  baseball for life by baseball commissioner Kenesaw Mountain Landis.</p><p>Jackson, John Hughlings (b. April 4, 1835, Green Hammerton,  Yorkshire, Eng.�d. Oct. 7, 1911, London) British neurologist. He showed  that most right-handed persons with aphasia had disease on the left side  of the brain, confirming Paul Broca�s findings. In 1863 he discovered  Jacksonian epilepsy (spasms progressing through the body), tracing it to  motor region damage. Electroencephalography has confirmed his 1873  definition of epilepsy as �a sudden, excessive, and rapid discharge� of  electricity by brain cells.</p><p>Jackson, Mahalia (b. Oct. 26, 1911, New Orleans, La., U.S.�d. Jan.  27, 1972, Evergreen Park, Ill.) U.S.  gospel music singer. As a child, Jack-  son sang in the choir of the New  Orleans church where her father  preached. She learned sacred songs  but was also exposed to blues record�  ings by Bessie Smith and Ida Cox. In  Chicago she worked at odd jobs  while singing with a touring gospel  quintet, and she opened several small  businesses. Her warm, powerful  voice first came to wide public atten�  tion in the 1930s, when she partici�  pated in a cross-country tour singing  songs such as �He�s Got the Whole  World in His Hands.� Closely asso�  ciated with Thomas A. Dorsey, she  sang many of his songs. �Move on  up a Little Higher� (1948) sold more  than a million copies, and she  became one of the most popular  singers of the 1950s and �60s. She  first appeared at Carnegie Hall in 1950. Active in the civil rights move�  ment from 1955, she sang at the epochal 1963 civil rights march on  Washington.</p><p>Jackson, Michael (Joseph) (b. Aug. 29, 1958, Gary, Ind., U.S.) U.S.  singer and songwriter. The nine-year-old Jackson became the lead singer  of The Jackson Five, a family group formed by his father. Their hits on  the Motown label included �I Want You Back� and �ABC.� Though  Michael remained a member of the group until 1984, he began recording  under his own name in 1971. His album Off the Wall (1979) sold millions;  his next solo album, Thriller (1982), sold more than 40 million copies,  becoming the best-selling album in history. The emerging format of the  music video was an important aspect of Jackson�s work; his videos for  �Beat It� and �Billie Jean� (both 1983) featured his highly influential  dancing style (notably his trademark �moonwalk�). He later released the  albums Bad (1987), Dangerous (1991), and HIStory (1995). Despite his  many efforts to speak out on social issues, Jackson�s eccentric, secluded  lifestyle stirred controversy in the early 1990s. His reputation was seri�  ously damaged in 1993 when he was accused of child molestation by a  13-year-old boy. Several of his siblings, notably his sister Janet (b. 1966),  have also enjoyed solo success.</p><p>Jackson, Reggie in full Reginald Martinez Jackson (b. May</p><p>18, 1946, Wyncote, Pa., U.S.) U.S. baseball player. Jackson excelled in  track, football, and baseball in high school.

He served as U.S. solicitor general (1938�  39) and attorney general (1940-41). In 1941 he was appointed by Pres.  Franklin Roosevelt to the U.S. Supreme Court, where he served until 1954.  He infused his well-worded opinions with a blend of liberalism and nation�  alism. In 1945�46 he served as chief U.S. prosecutor in the NOrnberg trials.</p><p>Jackson, Shirley (Hardie) (b.

She is best known for her story �The Lottery� (1948), a chill�  ing tale that provoked outrage when first published, and The Haunting of  Hill House (1959; film, 1963, 1999). These and her other five novels,  including We Have Always Lived in the Castle (1962), confirmed her  reputation as a master of gothic horror and psychological suspense.</p><p>Jackson, Stonewall orig. Thomas Jonathan Jackson (b. Jan.  21, 1824, Clarksburg, Va., U.S.�d. May 10, 1863, Guinea Station, Va.)  U.S. and Confederate army officer. Despite little formal education, he  secured an appointment to West Point. He served with distinction in the  Mexican War. At the start of the American Civil War, he organized Virginia  volunteers into an effective brigade. At the first Battle of Bull Run, he sta�  tioned his brigade in a strong line and withstood a Union assault, a feat  that earned him a promotion to major general and the nickname �Stone�  wall.� In 1862 he won campaigns in the Shenandoah Valley and later in  the Seven Days� Battles. Robert E. Lee used Jackson�s troops to encircle  the Union forces to win the second Battle of Bull Run, and Jackson  assisted Lee at Antietam and Fredericksburg. In April 1863, while mov�  ing his troops around the flank of the Union army at Chancellorsville, he  was accidentally shot and mortally wounded by his own men.</p><p>Jackson, William Henry (b.

After the American Civil War he  went west and opened a studio in Omaha. He was the official photogra�  pher for the U.S. Geological and Geographical Survey of the Territories  (1870-78), and his photographs were instrumental in the establishment of  Yellowstone National Park.</p><p>Jacksonville City (pop., 2000: 735,617), northeastern Florida, U.S. It  is the site of Florida�s first European (French Huguenot) settlement  (1564). Named for Andrew Jackson, it was laid out in 1822 and incorpo�  rated in 1832. It was largely destroyed by fire in 1901. In 1968 it was  consolidated with most of Duval county; it covers 841 sq mi (2,178 sq  km), making it one of the largest U.S. cities in terms of land area. A deep�  water port with major shipyards, it is Florida�s chief transportation and  commercial centre. It is the site of Jacksonville University, the Univer�  sity of North Florida, and Jones College.</p><p>Jacob Hebrew patriarch, son of Isaac and grandson of Abraham, and the  traditional ancestor of the people of Israel. His story is told in the Book  of Genesis. The younger twin brother of Esau, he used trickery to gain  Isaac�s blessing and Esau�s birthright. On a journey to Canaan he wrestled  all night with an angel, who blessed him and gave him the name Israel.  Jacob had 13 children, 10 of whom founded tribes of Israel. His favorite  son, Joseph, was sold into slavery in Egypt by his brothers, but the family  was later reunited when a famine forced the brothers to go to Egypt to  seek grain.</p><p>Jacob \zha-'kob\, Francois (b. June 17, 1920, Nancy, France) French  biologist. After receiving his doctorate, he went to work at the Pasteur  Institute in Paris. Beginning in 1958, he worked with Jacques Monod  studying the regulation of bacterial enzyme synthesis. They discovered  regulator genes, so called because they control the activities of other  genes. Jacob and Monod also proposed the existence of an RNA messen�  ger, a partial copy of DNA that carries genetic information to other parts  of the cell. The two men shared a 1965 Nobel Prize with Andre Lwoff.</p><p>Jacob ben Asher (b. 1269?, Cologne?�d. 1340?, Toledo, Castile)  Jewish legal scholar. He emigrated to Spain with his family in 1303, and  his father became chief rabbi in Toledo. Jacob is believed to have made  his living as a moneylender. He divided Jewish law into categories by  subject, producing a codification known as Tur, which became a popular  Jewish theological work of the 15th century. The basis for many rabbinic  decisions, it was considered standard until superseded by the work of  Joseph ben Ephraim Karo in the 16th century.</p><p>Jacobean \ ja-ko-'be-onV age Period in the visual and literary arts dur�  ing the reign of James I (Latin Jacobus) of England (r. 1603-25). Jacobean  architecture combines motifs from the late Gothic period with Classical  details and Tudor pointed arches and interior paneling. Jacobean furni�  ture, made of oak, featured heavy forms and bulbous legs. Inigo Jones,  following the theories and works of Andrea Palladio, introduced the Clas�  sical style of Renaissance architecture into England. Most Jacobean por�  traitists and sculptors were foreign-bom or foreign-influenced, and their  efforts faded when such Flemish painters as Peter Paul Rubens and Anthony  Van Dyck worked in England for James�s successor, Charles I. See also  Jacobean literature.</p><p>Jacobean \ ja-ko-'be-onV literature Body of works written during the  reign of James I of England (1603-25). The successor to Elizabethan litera�  ture, Jacobean literature was often dark in mood, questioning the stabil�  ity of the social order; some of William Shakespeare�s greatest tragedies  may date from the beginning of the period, and other dramatists, includ�  ing John Webster, were often preoccupied with the problem of evil. The  era�s comedy included the acid satire of Ben Jonson and the varied works  of Francis Beaumont and John Fletcher. Jacobean poetry included the  graceful verse of Jonson and the Cavalier poets but also the intellectual  complexity of the Metaphysical poetry of John Donne and others. In prose,  writers such as Francis Bacon and Robert Burton showed a new toughness  and flexibility of style. The era�s monumental prose achievement was the  King James Version of the Bible (1611).</p><p>Jacobin Vja-ko-bonV Club or Jacobins Political group of the French  Revolution, identified with extreme radicalism and violence. Formed in  1789 as the Society of the Friends of the Constitution, it was known as the  Jacobin Club because it met in a former convent of the Dominicans (known  in Paris as Jacobins). It was originally formed by deputies of the National  Assembly to protect the Revolution�s gains against a possible aristocratic  reaction. Although it did not have a direct role in overthrowing the mon�  archy in 1792, the club later changed its name to Society of the Jacobins,  Friends of Liberty and Equality. It admitted leftist Montagnard deputies of  the National Convention and agitated for the king�s execution and the over�  throw of the Girondins. In 1793, with about 8,000 clubs and 500,000 mem�  bers, the Jacobins became instruments of the Reign of Terror. The Parisian  club supported Maximilien Robespierre, but it closed after his fall in 1794.  Although officially banned, some local clubs lasted until 1800.</p><p>Jacobite In British history, a supporter of the exiled Stuart king James  II (in Latin, Jacobus) and his descendants after the Glorious Revolution of  1688. The movement was strong in Scotland, Wales, and Ireland, and it  included Catholics and Anglican Tories. The Jacobites, especially under  William III and Queen Anne, could offer a feasible alternative title to the  crown, and several attempts were made to restore the Stuarts. In 1689  James II landed in Ireland, but his army was defeated at the Battle of the  Boyne. In the Fifteen Rebellion (1715), led by John Erskine, 6th earl of  Mar (1675-1732), Jacobites tried to seize the crown for James Edward, the  Old Pretender. In the Forty-five Rebellion (1745) Charles Edward, the  Young Pretender, took Scotland, but the Jacobite army was crushed at the  Battle of Culloden (1746).</p><p>Jacobs, Helen Hull (1908 -1997) U.S. tennis player.Jacobs was the  national junior tennis champion in 1924-25. She was first defeated by  Helen Wills, who would prove to be her longtime rival, in the 1928 finals  at Forest Hills, N.Y. Though Wills was virtually always victorious, Jacobs  was a popular favourite. Her only victory over Wills came by default.  Though often in Wills�s shadow, Jacobs won four U.S. Open singles  (1932-35), three doubles (1932 and 1934-35), and mixed doubles (1934)  championships. She was ranked in the world�s top 10 from 1928 to 1940.  In 1933 she became the first woman to break with tradition by wearing  man-tailored shorts at Wimbledon. Her autobiography.

Jacopo  di Piero di Angelo (b. c. 1374, Siena�d. Oct. 20, 1438, Bologna,  Papal States) Italian sculptor active in Siena. He was the son of a gold�  smith and wood carver. His earliest major work is the tomb of Ilaria del  Carretto in Lucca Cathedral (c. 1406-08). His most important commis�  sion for Siena was the fountain known as Fonte Gaia (1408-19) in the  Piazza del Campo. He worked with Donatello and Lorenzo Ghiberti on  reliefs for the baptismal font in the Baptistery in Siena (1417-30). His  last and greatest work was the sculptural reliefs around the portal of San  Petronio in Bologna (1425-30). In 1435 he was appointed supervising  architect of Siena Cathedral. He elevated Sienese sculpture to a place of  prominence and influenced subsequent Sienese painters. The greatest non-  Florentine sculptor of the 15th century, he was a major influence on the  young Michelangelo.</p><p>Jacquard \zha-'kar,\ English \'ja-,kard\, Joseph-Marie (b. July 7,  1752, Lyon, Fr.�d. Aug. 7, 1834, Oullins) French inventor. In 1801 he  demonstrated an automatic loom incorporating revolutionary new tech�  nology; it was declared public property in 1806, and Jacquard was  rewarded with a pension and a royalty on each machine. His loom uti�  lized interchangeable punched cards that controlled the weaving of the  cloth so that any desired pattern could be obtained automatically. The  Jacquard loom�s technology became the basis of the modem automatic  loom and a precursor of the modern computer. His punched cards were  adapted by Charles Babbage as an input/output medium for his proposed  analytical engine and by Herman Hollerith to feed data to his census  machine, and punched cards were used for inputting data into early digi�  tal computers.</p><p>Jacquard \'ja-,kard\ loom Loom incorporating a special device to con�  trol individual warp yarns. It enabled production of fabrics with intricate  woven patterns such as tapestry, brocade, and damask, and has also been  adapted to the production of patterned knitted fabrics. Developed in  France by J.-M. Jacquard in 1804-05, it used interchangeable punched  cards that controlled the weaving of the cloth so that any desired pattern  could be obtained automatically. It aroused bitter hostility among weav�  ers, who feared that its labour-saving capabilities would deprive them of  jobs; the weavers of Lyon not only burned the machines but attacked Jac�  quard as well. Eventually the loom�s advantages led to its general accep�  tance, and by 1812 there were 11,000 in use in France. Use of the loom  spread to England in the 1820s and from there virtually worldwide.</p><p>Jacui \zha-'kwe\ River River, southern Brazil.

They  resemble dark gulls with a forward-  set black cap and projecting central  tail feathers. Jaegers have two colour  phases: all brown or (more com�  monly) brown above and white  below. They nest in the Arctic tundra  and then go to sea, many as far as  Australia and New Zealand. At sea  they catch fish on their own, but,  while nesting along coasts, they  force terns and kittiwakes to disgorge  their food, destroy the eggs and  young of other seabirds, and capture  land birds and rodents. The species range from 14 to 20 in. (35 to 50 cm)  long.

He was the great-  grandson of 'All As a possible claimant to the caliphate, Ja'far was viewed  as a threat to both the Umayyad and 'Abbasid dynasties. He traveled to  Baghdad in 762 to prove to the caliph that he was not seeking power, then  returned to his native Medina, where his pupils included Abu HanTfah.  After his death the Shl'ites began to splinter. One sect, the Isma'iliyyah,  became followers of his son, Ismail.

It was founded by  Jogaila, grand duke of Lithuania, who became Wladyslaw II Jagiello of  Poland after marriage to Queen Jadwiga (13737-99) in 1386. Wladyslaw  III Wamenczyk (1424-44) extended the dynasty by also assuming the  throne of Hungary (1440). He was succeeded by Casimir IV, who placed  his son on the thrones of Bohemia (1471) and Hungary. During the reigns  of Casimir�s sons John Albert (1459-1501) and Alexander (1461-1506),  the Jagiellon rulers lost much of their power in Poland to the nobility.  When Sigismund I succeeded Alexander in 1506, he strengthened the gov�  ernment and saw the Teutonic Order convert its lands into the secular  duchy of Prussia (1525), a Polish fief. In 1526 the death of Louis II ended  Jagiellon rule in Bohemia and Hungary. In 1561 Sigismund II Augustus  incorporated Livonia into Poland, but when he died, leaving no heirs, the  Jagiellon dynasty ended (1572).</p><p>jagirdar \j3-'gir-,dar\ system Form of land tenancy introduced in  India by the early sultans of Delhi in the early 13th century.

The land reverted to the government on the official�s  death, but heirs could renew the land assignment by paying a fee. Feu�  dalists in character, the jagirdar system tended to enfeeble the central  government by setting up quasi-independent baronies. Periodically abol�  ished, it was always renewed.

Though designated heir apparent, the impatient Jahangir  revolted in 1599; his father, Akbar, nevertheless confirmed him as his suc�  cessor. Like Akbar, Jahangir managed diplomatic relations on the Indian  subcontinent adroitly, was tolerant of non-Muslims, and was a great patron  of the arts.

As a teacher in Berlin from 1809, he began a pro�  gram of outdoor exercise for students. He invented the parallel bars, rings,  balance beam, horse, and horizontal bar, all of which have become stan�  dard equipment for gymnastics. In 1819 he came under suspicion for his  fervent nationalism and strong influence on youth. He was arrested and  imprisoned for almost a year; his gymnastic club closed, and a national  ban was placed on gymnastics (lifted in 1842). He was awarded the Iron  Cross for military bravery (1840) and served in the national parliament</p><p>(1848-49).</p><p>jahrzeit See yahrzeit</p><p>jai alai VhI-,11, .hl-o-'ll \ Basque "merry festival" Court game resem�  bling handball. Of Basque origin, it developed from pelota and was given  its present name when it was imported to Cuba in 1900. It is played  between two or four players with a ball and a hurling device consisting  of a long, curved wicker basket strapped to the wrist. The use of this hurl�  ing device, called a cesta, allows the ball to reach speeds up to 240 km/hr  (150 mph). The court, 53.3 m (58.3 yards) long, is three-walled. The  object of the game is to bounce the ball off the front wall with such speed  and spin that the opponent is unable to return it.

The first five are the mahavratas, or �great vows�:  nonviolence, truthfulness, not stealing, sexual purity, and renunciation of  possessions. These are interpreted more moderately for lay members than  for monks; for example, lay members need only remain sexually faithful  to their spouses, while monks must practice celibacy. The remaining vows  are designed to help in keeping the first five. The final vow is the prom�  ise to die in meditation during self-starvation when observance of the  other vows is no longer possible.</p><p>Jainism Vjl-.ni-zomV Religion of India established in the 6th century bce.  It was founded by Vardhamana, who was called Mahavira, as a reaction  against the Vedic religion, which required animal sacrifices. Jainism�s core  belief is AHIMSA, or noninjury to all living things. Jainism has no belief in  a creator god, though there are a number of lesser deities for various  aspects of life. Jains believe their religion is eternal and hold that it was  revealed in stages by a number of Conquerors, of whom Mahavira was  the 24th. Living as an ascetic, Mahavira preached the need for rigorous  penance and self-denial as the means of perfecting human nature, escap�  ing the cycle of rebirth, and attaining moksha, or liberation. Jains view  karma as an invisible material substance that interferes with liberation and  can be dissolved only through asceticism. By the end of the 1st century  ce the Jains had split into two sects, each of which later developed its own  canon of sacred writings: the Digambaras, who held that an adherent  should own nothing, not even clothes, and that women must be reborn as  men before they can attain moksha; and the more moderate Svetambaras,  who retained a few possessions such as a robe, an alms bowl, a whisk</p><p>broom, and a mukhavastrika (a piece of cloth held over the mouth to pro�  tect against the ingestion and killing of small insects). In keeping with  their principle of reverence for life, Jains are known for their charitable  works, including building shelters for animals. Jainism preaches univer�  sal tolerance and does not seek to make converts. In the early 21st cen�  tury Jainism had some 4.5 million followers.</p><p>Jaipur \'jl-,pur\ Capital (pop., 2001 prelim.: 2,324,319) of Rajasthan  state, northwestern India. A walled town surrounded by hills (except to  the south), it was founded in 1727 by Maharaja Sawai Jai Singh to replace  Amber as the capital of the princely state of Jaipur. The city, known for  its beauty, is unique in its straight-line planning; its buildings are mostly  rose-coloured, and it is sometimes called the �pink city.� It is a popular  tourist destination; historic structures include the city palace, the Hall of  Winds, Ram Bagh palace, and Nahargarh, or Tiger Fort.</p><p>Jakarta \p-kar-te\ formerly (1949-72) Djakarta Capital (pop., 1999  est.: 9,604,900) and largest city of Indonesia.

Born and educated in Moscow, Jakobson moved to Prague  in 1920; the European political situation forced him to flee to Scandina�  via in 1938 and to the U.S. in 1941. He taught at Harvard University  (1949-67). His interests ranged from folk epics and the cultural history  of the Slavs to general phonology, the morphology of the Slavic languages,  and speech acquisition. His preoccupation with contrast and opposition is  reflected in his analysis of the Russian case system (1938), a brilliant  analysis of the Russian verbal system (1948), and preeminently in his  work on distinctive features in phonology.</p><p>Jalal al-DIn al-Rum?

The Sierra Madre region is  largely volcanic, and earthquakes are frequent. The state�s many lakes  include Chapala, Mexico�s largest. First invaded by Spaniards in 1526,  Jalisco was incorporated into Nueva Galicia. In 1889 its area was much  reduced by the separation of the territory of Tepic (now Nayarit state) from  its coastal zone. Its economy is based on agriculture, livestock raising,  forest products, and mining.</p><p>jam See jelly and jam</p><p>Jamaica Island country, West Indies, located south of Cuba.

He is thought to have adopted the name Afghani to conceal the  fact that he was of Persian Shfite origin. He lived in Afghanistan from  1866, and a year later he became counselor to the khan. Displaced after  a change of rulers, he went to Istanbul and then to Cairo in 1871. After  becoming known as a rabble-rouser and heretic, he was deported from  Egypt in 1879. By 1883 he was in Paris, where he championed Islamic  civilization in the face of European domination. In Russia (1887-89) he  seems to have worked as an anti-British agitator. His next stop was Iran,  from which he was deported as a heretic in 1892; four years later he  avenged himself by instigating the shah�s murder.

His study of Toussaint-  Louverture, The Black Jacobins (1938), was a seminal work. During  James�s first stay in the U.S. (1938-53), he became friends with Paul  Robeson. Eventually deported to Britain because of his Marxism and  labour activism, James wrote on cricket for The Guardian. His Beyond  the Boundary (1963) mixes autobiography with commentary on politics  and sports.

He joined Benny Goodman�s band in  1937, becoming one of its principal soloists before forming his own group  in late 1938. The band achieved commercial success through recordings  featuring Frank Sinatra, virtuoso set pieces, and ballads performed with  James�s trademark wide vibrato. He married actress Betty Grable in 1943  and appeared in several films. An accomplished and technically brilliant  improviser, his music from the late 1940s reflected his renewed interest  in jazz, and he continued to perform with his band for more than 40 years.</p><p>James, Henry (b. April 15, 1843, New York, N.Y., U.S.�d. Feb. 28,  1916, London, Eng.) U.S.-British  novelist. Born to a distinguished  family, the brother of William James,  he was privately educated. He trav�  eled frequently to Europe from  childhood on; after 1876 he lived pri�  marily in England. His fundamental  theme was to be the innocence and  exuberance of the New World in con�  flict with the corruption and wisdom  of the Old. Daisy Miller (1879) won  him international renown; it was fol�  lowed by The Europeans (1879),</p><p>Washington Square (1880), and The  Portrait of a Lady (1881). In The  Bostonians (1886) and The Princess  Casamassima (1886), his subjects  were social reformers and revolu�  tionaries. In The Spoils of Poynton  (1897), What Maisie Knew (1897),  and The Turn of the Screw (1898), he  made use of complex moral and psy�  chological ambiguity. The Wings of  the Dove (1902), The Ambassadors  (1903), and The Golden Bowl (1904) were his great final novels. His  intense concern with the novel as an art form is reflected in the essay  �The Art of Fiction� (1884), his prefaces to the volumes of his collected  works, and his many literary essays. Perhaps his chief technical innova�  tion was his strong focus on the individual consciousness of his central  characters, which reflected his sense of the decline of public and collec�  tive values in his time.</p><p>James, Jesse and James, Frank in full Jesse Woodson  James and Alexander Franklin James (respectively b.

Brothers who were among the most notorious outlaws of the Ameri�  can West. Jesse and Frank both fought as Confederate guerrillas in the  American Civil War. In 1866 they and eight other men robbed a bank in  Liberty, Mo. Joined by other outlaws in subsequent years, the James gang  robbed banks from Iowa to Alabama and Texas. In 1873 the bandits began  robbing trains; they also preyed upon stagecoaches, stores, and individu�  als. In 1876 Jesse led a failed attempt to rob a bank in Northfield, Minn.;  though the brothers escaped, the rest of the gang was killed or captured.  After assembling a new gang in 1879 the brothers resumed robbing, and  in 1881 the governor of Missouri offered a $10,000 reward for the broth�  ers� capture, dead or alive. In 1882 Jesse was shot in the back of the head  and killed instantly by Robert Ford, a gang member, who claimed the  reward. A few months later, Frank gave himself up. Tried and acquitted  three times, he retired to a quiet life on his family�s farm.

His most famous  work is The Varieties of Religious  Experience (1902). In Pragmatism  (1907), he generalized the theories of  Charles Sanders Peirce to assert that  the meaning of any idea must be ana�  lyzed in terms of the succession of  experiential consequences to which it  leads and that truth and error depend  solely on these consequences (see  pragmatism). He applied this doctrine  to the analysis of change and chance,  freedom, variety, pluralism, and nov�  elty. His pragmatism was also the  basis for his polemic against monism,  the idealistic doctrine of internal rela�  tions, and all views that presented  reality as a static whole. He was also  a leader of the psychological move�  ment known as functionalism.</p><p>James I Spanish Jaime known as James the Conqueror (b. Feb.  2, 1208, Montpellier, County of Toulouse�d. July 27, 1276) King of  Aragon and Catalonia (1214-76). The most renowned of the medieval  kings of Aragon, he was educated by the Knights Templar, and his great-  uncle ruled as regent until 1218. James helped to subdue rebellious nobles  and took over the government of his kingdoms in 1227. He reconquered  the Balearic Islands (1229-35) and Valencia (1233-38) but renounced his  claims to lands in southern France. He also helped Alfonso X to suppress  a Moorish rebellion in Murcia (1266), and he undertook an unsuccessful  Crusade to the Holy Land (1269).</p><p>James I (b. June 19, 1566, Edinburgh Castle, Edinburgh, Scot.�d.  March 27, 1625, Theobalds, Hertfordshire, Eng.) King of Scotland, as  James VI (1567-1625), and first Stuart king of England (1603-25). He was  the son of Mary, Queen of Scots, and Lord Darnley, and at age one James  succeeded his mother to the Scottish throne. Controlled by a succession of  regents, he became the puppet of contending intriguers�Roman Catho�  lics, who sought to bring his mother back to the throne, and Protestants. In  1583 he began to pursue his own policies as king, allying himself with  England. On the death of Elizabeth I, he succeeded to the English throne as  great-great-grandson of Henry VII. He quickly achieved peace and prosper�  ity by ending England�s war with Spain (1604). He presided over the  Hampton Court Conference (1604), rejecting most of the Puritans�  demands for reform of the Church of England but permitting preparation of  a new translation of the Bible, the King James Version. His policies toward  Catholics led to the Gunpowder Plot, and his growing belief in royal abso�  lutism and his conflicts with an increasingly self-assertive Parliament led to  his dissolution of Parliament from 1611 to 1621. With the death of Robert  Cecil, he came under the influence of incompetent favourites.</p><p>James I (b. 1394�d. Feb. 20/21, 1437, Perth, Perth, Scot.) King of the  Scots (1406-37). The son and heir of Robert III, he was captured by the  English in 1406 and held prisoner in London until 1424. During the 13  years in which he truly ruled Scotland (1424-37), he established the first  strong monarchy the Scots had known in nearly a century. He weakened  the nobility but did not entirely subdue the Highland lords, and he greatly  improved the administration of justice for the common people. His mur�  der in a Dominican friary by a group of rival nobles led to a popular  uprising in favour of his widow and six-year-old son, who succeeded him  as James II.</p><p>James II Spanish Jaime known as James the Just (b. c. 1264�d.  Nov. 3, 1327, Barcelona, Aragon) King of Aragon (1295-1327) and king  of Sicily (as James I, 1285-95). He inherited the Sicilian crown on the  death of his father (1285); when his brother died (1291) he inherited Ara�  gon. He resigned Sicily (1295) and married the daughter of the king of  Naples in order to make peace with the Angevins. Sardinia and Corsica  were given to him in compensation for Sicily, but he was able to occupy  only Sardinia (1324).</p><p>James II (b. Oct. 14, 1633, London, Eng.�d. Sept. 16/17, 1701, Saint-  Germain, France) King of Great Britain (1685-88). He was brother and</p><p>successor to Charles II. In the English Civil Wars he escaped to the Neth�  erlands (1648). After the Restoration (1660) he returned to England and  became lord high admiral in the Anglo-Dutch Wars. He converted to  Catholicism c. 1668, and he resigned in 1673 rather than take the Test Act  oath. By 1678 his Catholicism had created a climate of hysteria about a  Popish Plot to assassinate Charles and put James on the throne, and suc�  cessive Parliaments sought to exclude him from succession. By the time  Charles died (1685), James came to the throne with little opposition and  strong support from the Anglicans. Rebellions caused him to fill the army  and high offices with Roman Catholics and suspend a hostile Parliament.  The birth of his son, a possible Catholic heir, brought about the Glorious  Revolution in 1688, and he fled to France. In 1689 he landed in Ireland to  regain his throne, but his army was defeated at the Battle of the Boyne,  and he returned to exile in France.</p><p>James II (b. Oct. 16, 1430, Edinburgh, Scot.�d. Aug. 3, 1460, Rox�  burgh Castle, Roxburgh) King of Scotland (1437-60). He succeeded to  the throne on the assassination of his father, James I of Scotland. Because  he was so young, the strong central authority his father had established  quickly collapsed, and his first adult task was the restoration of monar�  chical authority. He strove to dominate the powerful Douglas family, and  in 1452 he stabbed to death William, earl of Douglas, at Stirling Castle.  He established a strong central government and improved the adminis�  tration of justice. Turning his attention to the English, who had renewed  their claims to rule Scotland, he attacked English outposts in Scotland  and was killed during a siege of Roxburgh Castle.</p><p>James III (b. May 1452�d. June 11, 1488, near Stirling, Stirling, Scot.)  King of Scotland (1460-88). He succeeded his father, James II. Unlike the  latter, he was unable to restore strong central government after his long  minority. A weak monarch, he was confronted with two major rebellions.  He evidently offended his nobles by his interest in the arts and by taking  artists for his favourites. In 1488 two powerful border families raised a  rebellion and won to their cause his son, the future James IV; James III  was captured and killed at age 36.</p><p>James IV (b. March 17, 1473�d. Sept. 9, 1513, near Branxton,  Northumberland, Eng.) King of Scotland (1488-1513). He unified his  country, gaining control over all northern and western Scotland by 1493.  He fought border skirmishes with England (1495-97) in support of a pre�  tender to the English throne. His marriage (1503) to Margaret Tudor,  daughter of Henry VII, helped stabilize relations between the two coun�  tries, but in 1512 he allied with France against England. He invaded  England in support of the French in 1513; his army was defeated at the  Battle of Flodden, and James was killed.</p><p>James Bay Extension of Hudson Bay, located between northern Ontario  and Quebec, Can. Generally less than 200 ft (60 m) deep, it is 275 mi (443  km) long and 135 mi (217 km) wide. It contains numerous islands, of which  the largest is Akimiski Island. The many rivers that empty into the bay,  including the Moose, are the cause of its low salinity. Visited by Henry Hud�  son in 1610, it is named for Capt. Thomas James, who explored it in 1631.</p><p>James Edward, the Old Pretender orig. James Francis  Edward Stuart (b. June 10, 1688, London, Eng.�d. Jan. 1, 1766,  Rome, Papal States) Claimant to the English and Scottish thrones. Son of  the exiled James II of England, he was raised in France as a Catholic. On  the death of his father (1701), he was proclaimed king of England by the  French king Louis XIV, but the English Parliament passed a bill of attain�  der against him. He served with the French army in the War of the Span�  ish Succession. In the Jacobite uprising (1715), James landed in Scotland,  but within two months the uprising collapsed and he returned to France.  He lived thereafter in Rome under the pope�s patronage. He became  known as the �Old Pretender� to distinguish him from his son, Charles  Edward, the Young Pretender.</p><p>James River or Dakota River River in the U.S. rising in central  North Dakota and flowing southeast across South Dakota. It joins the  Missouri River about 5 mi (8 km) below Yankton after a course of 710 mi  (1,140 km). Major cities along the river include Jamestown, N.D., and  Huron, S.D.</p><p>James River River, Virginia, U.S. Formed by the junction of the Jack-  son and Cowpasture rivers, it flows east across the Blue Ridge and past  Richmond, then southeast to enter Chesapeake Bay through Hampton Roads  after a course of 340 mi (550 km).

Feb. 9, 1853, Edinburgh, Scot.�d.  Nov. 26, 1917, London, Eng.) British administrator in southern Africa. As  Cecil Rhodes�s representative, Jameson successfully negotiated mineral  concessions in Matabeleland and Mashonaland (present-day Zimbabwe)  before becoming the first administrator of the new colony of Rhodesia in  1893. In 1895 Rhodes and Jameson plotted with Uitlander (British) lead�  ers in the Transvaal to overthrow the Boer government of Paul Kruger; the  original plan was postponed, but Jameson carried out his own invasion  and was quickly captured with all his men. After imprisonment in  England, he returned to participate in South African politics.</p><p>Jamestown Colony First permanent English settlement in North  America. It was founded in May 1607 on a peninsula in the James River  of Virginia. Named after King James I, Jamestown began cultivating  tobacco and established the continent�s first representative government  (1619); the colony, its leader John Smith, and the Indian Pocahontas�  who, according to lore, saved Smith�s life�have been the subject of  numerous novels, dramas, and films, many of them highly fanciful. When  nearby Williamsburg replaced it as the capital of colonial Virginia in 1699,  it fell into decline. By the mid-19th century, erosion had transformed the  peninsula into Jamestown Island. In 1936 the site was incorporated into  the Colonial National Historical Park.</p><p>JamiVjo-.meW/g. Mawlana Nural-DIn 'Abd al-Rahman ibn  Ahmad (b. Nov. 7, 1414, district of Jam�d. Nov. 9, 1492, Herat, Timu-  rid Afghanistan) Persian scholar, mystic, and poet. Despite offers of  patronage by many Islamic rulers, he led a simple life, mostly in Herat.  His prose ranges from Qur�anic commentaries to treatises on Sufism and  music. His poetry expresses ethical and philosophical views in fresh,  graceful language. His best known poetry collection is The Seven Thrones  (or Ursa Major). He is often called the last great mystical poet of Iran.</p><p>Jamison, Judith (b.

In 1965 she joined Alvin Ailey�s American  Dance Theater; she became celebrated for her energetic grace and rivet�  ing stage presence and inspired many of Ailey�s new dances, most nota�  bly Cry (1971). She left the company in 1980 to star in the Broadway  musical Sophisticated Ladies. She toured worldwide in the 1980s and  choreographed for various companies. In 1988 she founded her own  troupe, the Jamison Project, but, after Ailey�s death in 1989, she returned  to the Ailey troupe as artistic director, becoming the first African Ameri�  can woman to direct a major modern dance company.</p><p>Jammu Vjo-miA City (pop., 2001 prelim.: 378,431) and winter capital  of Jammu and Kashmir state, northwestern India. It lies along the Tawi  River, south of Srinagar. Once the capital of the Dogra Rajput dynasty, it  became part of Ranjit Singh�s domain in the 19th century. It is now a  railroad and manufacturing centre. Sites of interest include a fort, a pal�  ace of the rajas, and the University of Jammu (founded 1969).</p><p>Jammu and Kashmir State (pop., 2001: 10,143,700), northern India.  With an area of 39,146 sq mi (101,387 sq km), it occupies the southern  portion of the Kashmir region of the northwestern Indian subcontinent and  is bordered by the portions of Kashmir administered by Pakistan and China  and by the Indian states of Himachal Pradesh and Punjab. The land is pre�  dominantly mountainous and includes segments of the Karakoram and  Himalaya ranges. Much of Kashmir�s Ladakh region is included in the state.  There are two major lowland areas: the Jammu plain and the fertile and  heavily populated Vale of Kashmir. The majority of the state�s people are  Muslims, although Hindus predominate in the southeastern Jammu area,  and northeastern Ladakh is largely Buddhist. Formerly a princely state cre�  ated in the 1840s, Jammu and Kashmir became an Indian state in 1947,  even as India and Pakistan were fighting for control of the entire Kashmir  region. A cease-fire line, established in 1949, has since served as the state�s  boundary with the Pakistan-administered area. Tension has remained high  in the region, and there have been periodic outbreaks of border fighting.</p><p>Janacek Vya-no-.chekV Leos (Eugen) (b. July 3, 1854, Hukvaldy,  Moravia, Austrian Empire�d. Aug. 12, 1928, Ostrava, Czech.) Czech  (Moravian) composer. Son of a church musician, he worked as a teacher  and choral conductor until age 40. When his marriage ended in 1887, he  began his first opera and spent the next year collecting folk songs. In 1894  he began his first mature opera, Jenufa, in a folk-influenced style; com�  pleted nearly a decade later, it had a successful premiere in Brno (1904),</p><p>and he retired to compose full-time,  becoming music�s most extraordi�  nary late bloomer. Major works of his  last two decades include the  Glagolitic Mass (1927) and the  operas Kat�a Kabanova (1921), The  Cunning Little Vixen (1924), The  Makropulos Affair (1925), and From  the House of the Dead (1928). A late  love affair inspired the Kreutzer and  Intimate Pages string quartets (1923,</p><p>1928).</p><p>Jane Seymour (b. 1509?,</p><p>England�d.

A lady-in-  waiting to Henry�s wives Catherine  of Aragon and Anne Boleyn, she  first attracted Henry�s attention c.</p><p>1535 but refused to be his mistress.</p><p>This probably hastened Anne  Boleyn�s downfall and execution (1536), after which Jane and Henry were  married privately. She restored Henry�s daughter Mary (later Mary I) to  his favour and gave birth to his only male heir, the future Edward VI, but  she died 12 days later, to Henry�s genuine sorrow.</p><p>Janissary Vja-no-.ser-eX also spelled Janizary Vja-n3-,zer-e\ Turkish  Yeniceri ("New Troop") Elite corps of the Ottoman Empire�s army  from the late 14th to the early 19th century. Its original soldiers were pris�  oners of war, but a system soon was developed (the devsirme ) wherein  Christian youths were levied from Balkan vassals, converted to Islam,  and�though paid a regular salary�inducted into the ranks of the sul�  tan�s slaves. They were, for the most part, infantry troops conscripted to  replace the often-unreliable Turkish tribal cavalry (spahi). Strict early  rules of behaviour, including celibacy, were later abandoned, and the Jan�  issaries became active in court politics. In 1826 they rebelled rather than  accept the reform of the army along European lines. The revolt was vio�  lently put down, and most of the Janissaries were killed.</p><p>Jansen Vyan-S3n,\ English Vjan-S3n\, Cornelius Otto (b. Oct. 28,  1585, Acquoi, near Leerdam, Holland�d. May 6, 1638, Ypres, Flanders,  Spanish Neth.) Flemish leader of the Roman Catholic reform movement  known as Jansenism. He studied at the University of Louvain, where he  absorbed the teachings of St. Augustine, especially those concerning origi�  nal sin and the need for grace. He spent 1611-14 in Bayonne, France,  where he directed the episcopal college. After studying theology three  more years, he returned to Louvain. He became rector of the university  in 1635 and a year later was appointed bishop of Ypres. In 1638 he died  of the plague. His major work, the Augustinus, was published in 1640; in  1642 Pope Urban VIII forbade the reading of the book.</p><p>Jansenism Roman Catholic reform movement inspired by the writings  of Cornelius Jansen. Influenced by the works of St. Augustine and espe�  cially by Augustine�s attacks on Pelagianism and the doctrine of free will,  Jansen adopted Augustine�s doctrines of predestination and the necessity  of God�s grace, a stance considered uncomfortably close to Calvinism by  Roman Catholic authorities, who banned his book the Augustinus in 1642.  After Jansen�s death in 1638, his followers made their base at the abbey  in Port-Royal, France. Blaise Pascal, the most famous Jansenist, defended  their teachings in his Provincial Letters (1656-57). In 1709 Louis XIV  ordered the Port Royal abbey demolished. Followers of Jansen started a  Jansenist church in 1723, which endured into the late 20th century.</p><p>Jansky, Karl (Guthe) (b. Oct. 22,1905, Norman, Okla., U.S.�d. Feb.  14,1950, Red Bank, N.J.) U.S. engineer. He graduated from the University  of Wisconsin and went to work for Bell Telephone Laboratories. Assigned  to track down sources of static that could interfere with radiotelephone  communication, he discovered (1931) the first extraterrestrial source of  radio waves, emanating from the constellation Sagittarius in the direction  of the Milky Way Galaxy�s centre. The discovery proved that celestial bod�  ies could emit radio waves and marked the beginning of radio astronomy.</p><p>Janus \'ja-nos\ Roman god of doorways and archways, after whom the  month of January is named.

It is separated  from the Asian mainland by the Sea  of Japan (East Sea). Area: 145,903 sq  mi (377,887 sq km). Population  (2005 est.): 128,085,000. Capital:</p><p>Tokyo. The Japanese overwhelm�  ingly are a single Asian ethnic group. Language: Japanese (official). Reli�  gions: Shinto, Buddhism; also Christianity. Currency: yen. Situated in one  of Earth�s most geologically active zones, Japan experiences volcanic  eruptions and earthquakes. Mountain ranges cover some four-fifths of its  land surface; its highest mountain is Mount Fuji. The economy, one of the  world�s biggest, is based largely on manufacturing and services; exports  include electronic and electrical equipment, motor vehicles, chemicals,  and iron and steel products. The government�s involvement in banking  results in unique cooperation between the public and private sectors. Japan  is one of the world�s principal seagoing nations, with an important marine  fishing sector. It is a constitutional monarchy with two legislative houses;  its symbol of state is the emperor, and the head of government is the prime  minister. Human habitation in Japan is thought to date to at least 30,000  years ago. The Yamato court established the first unified Japanese state  in the 4th-5th century ad; during that period, Buddhism arrived in Japan  by way of Korea. For centuries Japan borrowed heavily from Chinese  culture, but it began to sever its links with the mainland by the 9th cen�  tury. The Fujiwara family were dominant through the 11th century. In 1192  Minamoto Yoritomo established Japan�s first bakufu, or shogunate (see  Kamakura period). The Muromachi period (1338-1573) was marked by war�  fare among powerful families. Unification was achieved in the late 16th  and early 17th centuries under the leadership of Oda Nobunaga, Toyo-  tomi Hideyoshi, and Tokugawa Ieyasu. During the Edo (Tokugawa) period  (1603-1867), the government imposed a policy of isolation. Under the  leadership of the emperor Meiji (1867-1912), it adopted a constitution  (1889) and began a program of modernization and Westernization. Japa�  nese imperialism led to war with China (1894-95) and Russia (1904-05)  as well as to the annexation of Korea (1910) and Manchuria (1931). Dur�  ing World War II Japan attacked U.S. forces in Hawaii and the Philip�  pines (December 1941) and occupied European colonial possessions in  Southeast Asia. In 1945 the U.S. dropped atomic bombs on Hiroshima and  Nagasaki, and Japan surrendered to the Allies. A new democratic consti�  tution was drafted (1947) during the U.S. postwar occupation. Japan also  began rebuilding its ruined industrial base using new technology. A tre�  mendous economic recovery followed, and Japan became one of the  world�s wealthiest countries. It was able to maintain a favourable balance  of trade despite a long-term economic recession. See map on following  page.</p><p>Japan, Sea of or East Sea Branch of the western Pacific Ocean,  bounded by Japan, by Sakhalin Island, and by Russia and Korea on the  Asian mainland. It has a surface area of about 377,600 sq mi (978,000  sq km), a mean depth of 5,748 ft (1,752 m), and a maximum depth of  12,276 ft (3,742 m). Its relatively warm waters contribute greatly to the  mild climate of Japan. The growing trade among East Asian countries has  increased its use as a commercial waterway.</p><p>Japanese beetle Scarab beetle (Popillia japonica) that is a major pest  of plants. Introduced accidentally from Japan into the U.S. in 1916, Japa�  nese beetles are known to feed on more than 200 species of plant. Their  larvae feed underground on roots; adults feed on flowers, fruit, and foli�  age. They range from Maine to South Carolina, and infestations have  occurred in other parts of North America. The adult, about 0.4 in. (10  mm) long, is bright metallic green with coppery-brown wing covers. Con�  trol efforts include the use of poisonous sprays and a disease-inducing  bacterium and introduction of the beetle�s natural enemies (certain para�  sitic wasp and fly species).</p><p>Japanese crab See king crab</p><p>Japanese language Language spoken by about 125 million people  on the islands of Japan, including the Ryukyus. The only other language  of the Japanese archipelago is Ainu (see Ainu), now spoken by only a  handful of people on Hokkaido, though once much more widespread.  Japanese is not closely related to any other language, though a distant  genetic kinship to Korean is now thought probable by some scholars, and  an even more remote relationship to the Altaic languages is possible.  Japanese is first attested in the 8th century ad, when Middle Chinese char�  acters were utilized solely for their phonetic value to write native Japa�  nese words. Japanese retains a huge stock of loanwords from Middle  Chinese, long adapted to native phonetics.</p><p>Japanese law Law as it has developed in Japan as a consequence of  the combination of two cultural and legal traditions, one indigenous Japa�  nese, the other Western. In the 8th century Japan borrowed and adapted  the legal system of the Chinese Tang dynasty. With the rise of the warrior  class, clan codes governing the behaviour and actions of warrior families  were developed. After the Meiji Restoration (1868), Japan began to bor�  row heavily from European legal systems, particularly the German Civil  Code. After World War II, largely as a result of the country�s occupation  by the U.S. military and later contacts with U.S. legal scholars, Japan  incorporated aspects of the U.S. legal system, including various civil pro�  cedures and elements of labour and business law. Traditional extralegal  dispute-resolution methods remain strong, and litigation plays a less per�  vasive role than in the U.S.</p><p>Japanese philosophy Conceptual expression of Japanese culture  since early 6th century ad. Japanese philosophy is not generally indig�  enous; Japanese thinkers have always skillfully assimilated alien philo�  sophical categories in developing their own systems. One of the two  principal schools of Japanese thought arose from Buddhism and was highly  tinged with a religious and often somewhat metaphysical character. The  second school arose from Confucianism and was essentially a system of  moral philosophy. Since the Meiji Restoration (1868), Western philosophy  has been abundantly introduced into Japan. At first British and American  philosophies predominated, but in the 20th century the influence of Ger�  man philosophy became increasingly strong; leading Japanese philoso�  phers were especially influenced by German idealism, phenomenology, and  existentialism. To distinguish Western philosophy from Buddhist and Chi�  nese thought, the term tetsugaku (�wise learning�) was coined and has  come into common use.</p><p>Japanese writing system System of modified Chinese characters  used for writing the Japanese language. The Japanese developed a mixed  system, partly logographic (based on the Chinese writing system) and partly  syllabic. In the 9th or 10th century two sets of syllabic signs evolved:  hiragana, simplified cursive versions of Chinese characters; and kata-  kana, based on elements of Chinese characters. Modem Japanese is writ�  ten with the two syllabaries and Chinese characters.</p><p>Japura \,zha-pu-'ra\ River River, northwestern South America.

Afterward it flows through southeastern Colom�  bia and is joined by the Apaporis River at the Brazilian border, where it  takes the name Japura and flows eastward to join the Amazon River. Its  total length, including the Caqueta, is about 1,750 mi (2,820 km). It has  a strong current and is navigable by small boats in Brazil.</p><p>Jaques-Dalcroze Vzhak-.dal-'krozV Emile (b.

He studied composition with Anton Bruckner, Gabriel Faure, and  Leo Delibes, and in 1892 he became professor of harmony at the Geneva  Conservatory. In the early 20th century he experimented with new meth�  ods of music education, which evolved into eurythmics, a system in which  bodily movements are used to represent musical rhythms. In 1914, hav�  ing left the conservatory, he founded the Institut Jaques-Dalcroze in  Geneva to teach and promulgate his new method.</p><p>Jari River or Jary \zha-'re\ River River, northern Brazil.

He  played with Art Blakey (1965-66) and  with Miles Davis�s jazz-rock group  (1970-71) before making a series of  solo recordings that won him broad  popularity. His trio (from 1966) with  bassist Charlie Haden (b. 1937) and  drummer Paul Motian (b. 1931), later  expanded to a quartet (1971-76), was  highly regarded. By the 1980s his  public performance had turned  mainly to classical recitals.</p><p>Jarry \zha-'re\, Alfred (b. Sept. 8,</p><p>1873, Laval, France�d. Nov. 1,</p><p>1907, Paris) French writer. He went  to Paris to live on his inheritance at  age 18; after exhausting it, he led a  life of calculated buffoonery. His  farce Ubu Roi (1896), considered a  forerunner of theatre of the absurd  and of Surrealism, featured the gro�  tesque Pere Ubu, who becomes king  of Poland. Jarry followed it with two sequels, one of which was published  posthumously. The brilliant imagery and wit of his stories, novels, and  poems usually lapse into incoherence and unintelligible symbolism. A  heavy drinker, he died at 34.</p><p>Jaruzelski \,yar-u-'zel-ske\, Wojciech (Witold) (b. July 6, 1923,  Kurow, Pol.) Polish army general and chief of state (1981-89) and presi�  dent (1989-90) of Poland. He rose through the ranks of the army and the  Communist Party to be elected premier and first secretary of the party in  1981 as Poland came under increasing pressure from the Solidarity move�  ment. He declared martial law (1981-83), carrying out mass arrests of  dissidents. Unable to restore Poland�s stagnant economy, he began nego�  tiations in 1988 with Solidarity, culminating in agreements to reform  Poland�s political system. Elected president in 1989, he resigned his posts  in the Communist Party. In 1990 Lech  Walesa was elected president, and  Jaruzelski relinquished the last of  communist power in Poland.</p><p>jasmine Vjaz-monN Any of about  300 tropical and subtropical species  of fragrant, flowering, woody, climb�  ing shrubs that make up the genus  Jasminum of the olive family, native  to all continents except North  America.

As a research psychiatrist, he helped establish psychopathol�  ogy on a rigorous, scientifically descriptive basis, especially in his Gen�  eral Psychopathology (1913). He taught philosophy at the University of  Heidelberg from 1921 until 1937, when the Nazi regime forbade him to  work. From 1948 he lived in Switzerland, teaching at the University of  Basel. In his magnum opus. Philosophy (3 vol., 1969), he argued that the  aim of philosophy is practical; its purpose is the fulfillment of human  existence ( Existenz ). For Jaspers, philosophical illumination is achieved  in the experience of limit situations, such as conflict, guilt, and suffering,  that define the human condition. In its confrontation with these extremes  mankind achieves its existential humanity. He is one of the most impor�  tant figures of EXISTENTIALISM.</p><p>Jassy See Iasi</p><p>Jassy \'ya-se.

After 1899 the  socialists split into two groups, and  Jaures headed the French Socialist  Party, advocating reconciliation with  the state. In the newspaper  L�Humanite, which he cofounded in  1904, he espoused democratic  socialism, but when the Second Inter�  national (1904) rejected his position  he acquiesced. In 1905 the two  French socialist parties united, and  his authority continued to grow. On  the eve of World War I, he espoused  peace through arbitration and cham�  pioned Franco-German rapproche�  ment, which earned him the hatred of  French nationalists, and he was assassinated in 1914 by a young nation�  alist fanatic. He wrote several books, including the influential Socialist  History of the French Revolution (1901-07).</p><p>Java \'ja-va\ Indonesian Djawa Island (pop., 2000 prelim.:  121,352,608), Indonesia. Lying southeast of Sumatra, it is Indonesia�s  fourth largest island, and it contains more than half of the country�s popu�  lation. Its area, including offshore Madura Island, is 49,228 sq mi  (127,499 sq km). The capital of Java and of Indonesia is Jakarta. The  island�s highest point is Mount Semeru, an active volcano measuring  12,060 ft (3,676 m) high. It is inhabited by three major ethnic groups: the  Javanese (who constitute 70% of the population), the Sundanese, and the  Madurese. The fossilized remains of Homo erectus, or �Java man,� indi�  cate that the island was occupied some 800,000 years ago. Indian traders  began arriving in the 1st century ad, bringing Hindu influences. The  Majapahit dynasty was founded in eastern Java in 1293; it fell early in  the 16th century when Muslim kingdoms arose. In 1619 the Dutch East  India Company took control of Batavia (Jakarta) and extended its influ�  ence. Ruled by the Dutch until the 1940s when it was occupied by Japan,  it became part of newly independent Indonesia in 1950.</p><p>Java Modular object-oriented programming language developed by Sun  Microsystems in 1995 specifically for the Internet.

The most visible  examples of Java software are the interactive programs called �applets�  that animate sites on the World Wide Web, where Java is a standard cre�  ative tool. Java provides an interface to HTML.</p><p>Java man Common name of fossilized Homo erectus remains found in  1891 at Trinil, Java. The remains, a skullcap and thighbone, represent the  first known fossils of H. erectus (though originally assigned to Pithecan�  thropus erectus ) and, together with numerous other finds along the Solo  River, suggest that H. erectus was present in eastern Asia some 1,000,000  years ago and persisted there for at least 500,000 years and possibly as  long as 800,000 years. Java man predates the finds at Zhoukoudian (Peking  Man) in China and is considered somewhat more primitive.</p><p>Java Sea Part of the western Pacific Ocean between Java and Borneo  islands. Measuring 900 mi (1,450 km) long by 260 mi (420 km) wide, it  occupies a total area of 167,000 sq mi (433,000 sq km). A shallow sea, it  has a mean depth of 151 ft (46 m). It was the scene of a World War II  naval battle (1942) that resulted in an Allied defeat and Japan�s invasion  of Java.</p><p>Javanese Any member of the largest ethnic group on the island of Java,  Indonesia. They speak an Austronesian language. The Javanese are Mus�  lim, though relatively few are strictly observant. Traditional Javanese  social organization varied in structure from relatively egalitarian villages  to the highly stratified society of the cities; these differences find expres�  sion in the many Javanese styles of speech still in use. Javanese villages  are compact groups of single-family houses, generally built of bamboo,  surrounding a central square. Rice is the main food crop. The growth of  large cities in Java has produced an urban underclass who live in make�  shift huts in enclosed neighbourhoods.</p><p>JavaScript Computer programming language developed by Netscape in  1995 for use in HTML pages.

In France in 1905 he worked with Henri Matisse. Back in  Munich he produced works featuring flat areas of vibrant Fauve colour  outlined with simple, thick contours. In Switzerland during World War I  he painted a series of �variations� on the view from his window. Their  meditative mood culminated in such semiabstract faces as Looking Within  Night (1923), whose mystical intensity is reminiscent of Russian icon  painting. In 1924 he joined Vasily Kandinsky, Paul Klee, and Lyonel Fein-  inger to form Der Blaue Vier (�The Blue Four�); they exhibited together  until arthritis forced Jawlensky to abandon painting.</p><p>Jean Jaures.</p><p>H.

May 17, 1829, New  Bedford, N.Y., U.S.) U.S. jurist, first  chief justice of the Supreme Court of  the United States. He practiced law in  New York City. Though he initially  deplored the growing conflict  between Britain and the colonies, he  became a staunch supporter of inde�  pendence once the revolution was  launched. He helped assure the approval of the Declaration of Indepen�  dence (1776) in New York, where he was a member of the provincial  Congress. The following year he helped draft New York�s first constitu�  tion and was elected the state�s first chief justice, and in 1778 he was  chosen president of the Continental Congress. In 1782 he joined Benjamin  Franklin in Paris to negotiate terms of peace with Britain. On his return  from abroad, Jay found that Congress had elected him secretary for for�  eign affairs (1784�90). Convinced of the need for a stronger centralized  government, he urged ratification of the U.S. Constitution. Under the  pseudonym Publius, he wrote five of the essays that later became known  as the Federalist papers (the others were written by James Madison and  Alexander Hamilton); published in New York newspapers in 1787-88, the  essays were a masterly defense of the Constitution and republican gov�  ernment. As the first chief justice of the Supreme Court (1789-95), he set  legal precedent by affirming the subordination of the states to the federal  government. In 1794 he was sent to Britain to negotiate a treaty dealing  with numerous commercial disputes. The Jay Treaty helped avert war, but  critics contended that it was too favourable to Britain. Jay resigned from  the court and was elected governor of New York (1795-1801).</p><p>Java, Mount Indonesian Puncak Jaya formerly Mount  Sukarno Peak, Papua (Irian Jaya) province, Indonesia.

Born into  the royal family of Angkor, he settled in the Champa kingdom (present-day  central Vietnam) in his young adulthood and engaged in military cam�  paigns. In his late fifties he led his people in a struggle for independence  after their subjugation by the Cham. He was crowned king of a reconsti�  tuted Khmer empire at 61. He ruled more than 30 years and brought the  empire to its zenith in terms both of territorial extent and of royal archi�  tecture and construction. Champa, southern Laos, and portions of the  Malay Peninsula and Myanmar (Burma) came under his control. He built  temples, hospitals, and rest houses, and rebuilt the city of Angkor (now  called Angkor Thom).

Though its specific origins are not known, the music developed  principally as an amalgam in the late-19th- and early 20th-century musi�  cal culture of New Orleans. Elements of the blues and ragtime in particu�  lar combined to form harmonic and rhythmic structures upon which to  improvise. Social functions of music played a role in this convergence:  whether for dancing or marching, celebration or ceremony, music was tai�  lored to suit the occasion. Instrumental technique combined Western tonal  values with emulation of the human voice. Emerging from the collective  routines of New Orleans jazz (see Dixieland), trumpeter Louis Armstrong  became the first great soloist in jazz; the music thereafter became prima�  rily a vehicle for profoundly personal expression through improvisation and  composition. Elaboration of the role of the soloist in both small and large  ensembles occurred during the swing era (c. 1930-45), the music of pia�  nist and bandleader Duke Ellington in particular demonstrating the com�  bination of composed and improvised elements. In the mid-1940s  saxophonist Charlie Parker pioneered the technical complexities of bebop  as an outgrowth of the refinement of swing: his extremes of tempo and  harmonic sophistication challenged both performer and listener. The trum�  peter Miles Davis led groups that established the relaxed aesthetic and lyri�  cal phrasing that came to be known as cool jazz in the 1950s, later  incorporating modal and electronic elements. Saxophonist John Col-  trane�s music explored many of the directions jazz would take in the  1960s, including the extension of bebop�s chord progressions and experi�  mental free improvisation.</p><p>Jeans, Sir James (Hopwood) (b.

His lyrics  express contempt for humanity and love of the harsh, eternal beauties of  nature, notably the California coast near Carmel, where he moved in 1916.  His third book, Tamar and Other Poems (1924), cemented his reputation  and revealed the unique style and eccentric ideas he later developed in  Cawdor (1928), Thurso�s Landing (1932), and Be Angry at the Sun (1941).</p><p>Jefferson, Thomas (b.

A delegate  to the Second Continental Congress, he was appointed to the committee to  draft the Declaration of Independence and became its primary author. He was  elected governor of Virginia (1779-81) but was unable to organize effec�  tive opposition when British forces invaded the colony (1780-81). Criti�  cized for his conduct, he retired, vowing to remain a private citizen. Again  a member of the Continental Congress (1783-85), he drafted the first of the  Northwest Ordinances for dividing and settling the Northwest Territory. In  1785 he succeeded Benjamin Franklin as U.S. minister to France. Appointed  the first secretary of state (1790-93) by George Washington, he soon  became embroiled in a bitter conflict with Alexander Hamilton over the  country�s foreign policy and their opposing interpretations of the Consti�  tution. Their divisions gave rise to political factions and eventually to  political parties. Jefferson served as vice president (1797-1801) under John  Adams but opposed Adams�s signing of the Alien and Sedition Acts (1798);  the Virginia and Kentucky Resolutions, adopted by the legislatures of those  states in 1798 and 1799 as a protest against the Acts, were written by Jef�  ferson and James Madison. In the presidential election of 1800 Jefferson and  Aaron Burr received the same number of votes in the electoral college; the  decision was thrown to the U.S. House of Representatives, which chose  Jefferson on the 36th ballot. As president, Jefferson attempted to reduce the  powers of the embryonic federal government and to eliminate the national  debt; he also dispensed with a great deal of the ceremony and formality that  had attended the office of president to that time. In 1803 he oversaw the  Louisiana Purchase, which doubled the land area of the country, and he  authorized the Lewis and Clark Expedition. In an effort to force Britain and  France to cease their molestation of U.S. merchant ships during the Napo�  leonic Wars, he signed the Embargo Act. In 1809 he retired to his plantation,  Monticello, where he pursued his interests in science, philosophy, and  architecture. He served as president of the American Philosophical Society  (1797-1815), and in 1819 he founded and designed the University of Vir�  ginia. In 1812, after a long estrangement, he and Adams were reconciled  and began a lengthy correspondence that illuminated their opposing politi�  cal philosophies. They died within hours of each other on July 4, 1826, the  50th anniversary of the signing of the Declaration of Independence.  Though a lifelong slaveholder, Jefferson was an anomaly among the Vir�  ginia planter class for his support of gradual emancipation. In January 2000  the Thomas Jefferson Memorial Foundation accepted the conclusion, sup�  ported by DNA evidence, that Jefferson had fathered at least one child with  Sally Hemings, one of his house slaves.</p><p>Jefferson City City (pop., 2000: 39,636), capital of Missouri, U.S.  Located on the Missouri River near the centre of the state, it was selected  as the site of the state capital in 1821.

The  Capitol, completed in 1918, contains murals by Thomas Hart Benton. It is  the trading centre for surrounding farmlands and has diversified manu�  facturing.

In geophysics, he investigated the thermal history  of the Earth, was coauthor (1940) of the standard tables of travel times  for earthquake waves, and was the first to hypothesize that the Earth�s  core is liquid.

The Witnesses are a millennialist group whose beliefs are  based primarily on the apocalyptic sections of the Bible, notably Daniel  and the Book of Revelation. They refuse to perform military service or  salute the flag, actions which have brought them into direct conflict with  governments around the world. They are famous for their door-to-door</p><p>evangelizing and for refusing blood transfusions; they believe there is  scriptural justification for all their actions and beliefs. Their goal is the  establishment of God�s kingdom on earth, and they hold that Jesus �who  is believed to be God�s first creation rather than one person in a trinity�is  God�s agent in this plan. Their national headquarters is in Brooklyn, N.Y.;  their major publications, the Watchtower and Awake!, are published in  about 80 languages. See also millennialism.</p><p>Jekyll, Gertrude (b. Nov. 29, 1843, London, Eng.�d. Dec. 8, 1932,  London) British landscape architect. She pursued painting until 1891,  when she turned to garden design. She helped the landscape designer  William Robinson (1838-1935) in his writings about the natural garden  and wrote several successful books on her own, including Wood and Gar�  den (1899) and Home and Garden (1900). Her taste was for the simplic�  ity and orderly disorder of cottage gardens. She later worked closely with  Edwin L. Lutyens, developing a modem, informal style of garden marked  by a rhythmic use of colour and form.</p><p>Jelinek, Elfriede (b. Oct. 20, 1946, Miirzzuschlag, Austria) Austrian  novelist and playwright. At age 17 she suffered an emotional breakdown,  and during her recovery she turned to writing as a form of self-expression  and introspection. A polemical feminist, Jelinek often wrote about gen�  der oppression and female sexuality. She also rejected the conventions of  literary tradition in favour of linguistic and thematic experimentation.  Among her notable novels are Wonderful, Wonderful Times (1980), The  Piano Teacher (1983; filmed 2001), and Lust (1989). She also wrote a  number of plays, including Clara S. (1984) and Bambiland (2003). In  2004 Jelinek won the Nobel Prize for Literature.</p><p>Jellicoe, John Rushworth Jellicoe, 1st Earl (b. Dec. 5, 1859,  Southampton, Hampshire, Eng.�d. Nov. 20, 1935, London) British admi�  ral. He entered the Royal Navy in 1872 and rose through the ranks to  become commander of the fleet during World War I (1914-16). He won  a crucial victory in the Battle of Jutland (1916), after which he was pro�  moted to first sea lord of the Admiralty (1916-17) and admiral of the fleet  (1919). He served as governor of New Zealand (1920-24).</p><p>Jellinek Vje-li-,nek\, Elvin M(orton) (b. Aug. 15, 1890, New York,  N.Y., U.S.�d. Oct. 22, 1963, Palo Alto, Calif.) U.S. physiologist. He  studied at the University of Leipzig and worked in Budapest, Sierra  Leone, and Honduras before returning to the U.S., where he studied alco�  holism. He was an early proponent of the theory that alcoholism should  be treated as a disease. He gathered and summarized his and others�  research in the authoritative Alcohol Explored (1942) and The Disease  Concept of Alcoholism (1960).</p><p>jelly and jam Thick preserves made from fruit and sugar. Jelly is  semitransparent, consisting of the strained juice of various fruits (occa�  sionally vegetables), singly or in combination, that is sweetened, slowly  simmered, and congealed, often with the aid of pectin or gelatin. Jam dif�  fers from jelly in its inclusion of fruit pulp or whole fruit; whole-fruit jam  is sometimes called preserve. Fruit jellies and jams are eaten on break�  fast breads and in sandwiches and accompany the scones and other baked  goods of the British tea meal. Vegetable and herb jellies traditionally  complement lamb and other meat dishes.</p><p>jellyfish Any of about 200 described species of free-swimming marine  cnidarians (in the classes Scyphozoa and Cubozoa), many of which have  a bell-shaped body. The term is also frequently applied to other similar  cnidarians (e.g., Portuguese man-of-war) and some unrelated forms (e.g.,  ctenophores and salps). In scyphozoan jellyfish, the free-swimming medusa  form is the dominant stage, with the sessile polyp form found only during  larval development. Jellyfish live in all oceans and include the familiar  disk-shaped animals that are often found drifting along the shoreline. Most  species are 1-16 in. (2-40 cm) in diameter; some are 6 ft (1.8 m) in diam�  eter, with tentacles more than 100 feet (30 m) long. Though some jelly�  fish simply filter-feed, most feed on small animals (e.g., crustaceans) that  they catch in their tentacles, whose stinging cells immobilize the prey;  contact can be irritating and sometimes dangerous to humans. The cubo-  zoan jellyfish comprise 50 species of box jellies (the rather spherical body  is squared off at the edges), which are usually 1-2 in. (2-4 cm) in diam�  eter.

In 1806 Frederick William III of Prussia signed  a secret alliance with Russia and joined the Third Coalition against Napo�  leon. As the Prussian army moved through Saxony to meet its Russian  allies, it was forced to face a French attack from the rear. The Prussians  split their forces between Auerstedt and Jena, and on October 14 Napo�  leon swept the Prussian troops off the field at Jena. At the same time, a  secondary French force under Louis Davout defeated a Prussian army more  than twice its size at Auerstedt.

In high  school Jenkins excelled in amateur baseball, basketball, and hockey. He  began his major league career with the Philadelphia Phillies in the early  1960s, before playing for the Chicago Cubs, the Texas Rangers, and the  Boston Red Sox, winning at least 20 games in each of six consecutive  seasons (1967-72) and setting several season records. He was awarded  the Cy Young award in 1971 for his 24-13 won-lost record and 2.77  earned run average.</p><p>Jenkins (of Hillhead), Roy (Harris) Jenkins, Baron (b.

A strong supporter of  NATO and the European Community, he was president of the executive  branch of the latter (1976-81). He resigned from the Labour Party, and  in 1981, with other Labour dissidents, he formed the Social Democratic  Party, which he led in 1982-83. After accepting a life peerage (1987), he</p><p>became leader of the Social and Liberal Democratic Party in the House  of Lords. He subsequently became chancellor of the University of Oxford.</p><p>Jenkins' Ear, War of War between Britain and Spain that began in  1739 and eventually merged into the War of the Austrian Succession. In  1738 Capt. Robert Jenkins appeared before a committee of the House of  Commons and exhibited his own amputated ear, which he alleged was cut  off by Spanish coast guards who boarded his ship in the West Indies in  1731. Public opinion had already been aroused by other Spanish outrages  on British ships, and the incident was exploited by members of Parlia�  ment who opposed the government of Robert Walpole.</p><p>Jenner, Edward (b.

He was appren�  ticed to a surgeon at 13, and at 21 he  became the house pupil of John  Hunter, who gave him further train�  ing and stressed the need for experi�  mentation and observation. Jenner  had noticed as a youth that people  who had been sick with the relatively  harmless disease cowpox did not  contract smallpox. In 1796 he inocu�  lated a young boy with matter taken  from a dairymaid�s fresh cowpox  lesions. The boy caught cowpox and,  when subsequently inoculated with  smallpox, did not contract it. Despite  early difficulties, the procedure  spread and the death rate from small�  pox fell. Jenner received worldwide  recognition (though he was also sub�  ject to attacks and slander). He retired from public life in 1815 after the  death of his wife.</p><p>Jensen \'yen-son\, Georg (b. Aug. 31, 1866, Raadvad, Den.�d. Oct.  2, 1935, Copenhagen) Danish silversmith and designer. At age 14 he was  apprenticed to a goldsmith, and in 1904 he opened his own workshop in  Copenhagen. Exhibiting his silverware and jewelry at major foreign exhi�  bitions, he quickly built a reputation as an outstanding and original sil�  versmith. He was the first to realize a profit from the manufacture of  modern silverware and among the first to fashion steel into handsome,  serviceable cutlery. By 1935 his firm had stores all over the world and  carried more than 3,000 patterns. After his death the business was con�  tinued by his son, Spren Georg Jensen (b. 1917).</p><p>Jensen \'yen-son\, Johannes V(ilhelm) (b. Jan. 20, 1873, Farsp,  Den.�d.

He first made  an impression as a writer of tales, including the more than 100 published  under the recurring title Myths. His early writings also include a histori�  cal trilogy. The Fall of the King (1900-01), about Christian II of Denmark.  His best-known work is The Long Journey (1908-22), a series of six nov�  els that chronicles humanity�s rise from primitive times to the time of  Christopher Columbus�s arrival in the Americas. He received the Nobel  Prize for Literature in 1944.</p><p>Jephtha \'jef-tho\ One of the judges in ancient Israel. According to the  Book of Judges, he was the son of a Gileadite and a prostitute. After being  cast out by his father�s legitimate sons, he joined a band of brigands. When  the Gileadites were oppressed by an Ammonite army, they asked Jephtha  to aid them. He led them to victory, having first promised God a sacrifice  of whatever he first saw when he left his house; his first sight happened  to be his daughter. His significance in the Book of Judges is as an exem�  plar of Israel�s fidelity to God.</p><p>Jeremiah (b. probably after 650, Anathoth, Judah�d. c. 570 bc, Egypt)  Hebrew prophet and reformer, author of the book of Jeremiah.

Incor�  porated into Jordan in 1950, it  became the site of two huge camps  of Arab refugees following the first  Arab-Israeli war (1948). In the Six-  Day War (1967), the town was occu�  pied by Israel, and much of the  refugee population was dispersed. In  1994 it was turned over to the Palestinian Authority under an Israeli-  Palestinian self-rule agreement.</p><p>Jerome, Chauncey (b. June 10, 1793, Canaan, Conn., U.S.�d. April  20, 1868, New Haven, Conn.) U.S. inventor and clockmaker. In 1824 he  designed a popular bronze looking-glass clock, and he formed a company  that soon became the leading U.S. clockmaker. He invented the one-day  brass movement, an improvement over the wood clock. Applying mass-  production techniques, he flooded the U.S. with low-priced brass clocks,  which quickly spread to Europe and so astonished the English that �Yan�  kee ingenuity� became a byword.</p><p>Jerome, Saint' (b. c. 347, Stridon, Dalmatia�d. 419/420, Bethlehem,  Palestine) Church Father and biblical translator. Born into a wealthy  Christian family in Dalmatia, he was educated there and in Rome. Bap�  tized c. 366, he spent most of the next 20 years in travel. He lived two  years as a hermit in the desert of Chalcis. From 377 to 379 Jerome was  in Antioch, where he studied biblical texts and translated the works of  Origen and Eusebius. He lived in Rome (382-85), but theological contro�  versy and opposition to his ascetic views led him to depart for the Holy  Land, and he settled in Bethlehem, where he lived until his death. Tra�  ditionally regarded as the most learned of the Latin Fathers, he wrote  numerous biblical commentaries and theological tracts on Pelagianism and  other heresies. In 406 he completed his translation of the Bible into Latin,  including his own translation of the Old Testament from Hebrew; Jer�  ome�s Latin Bible is known as the Vulgate.</p><p>Jersey Largest and southernmost of the Channel Islands, in the English  Channel. Area: 44.9 sq mi (116.2 sq km). Population (2002 est.): 87,400.  Capital: St. Helier (pop., 2001: 28,310). Separated from Normandy in  1204, it kept its Norman law and local customs but was administered for  the British king by a warden. It was given legislative authority in 1771.  It is now governed by a popularly elected assembly, which is presided  over by a royally appointed bailiff. There is also a lieutenant governor,  who represents the British monarch. Jersey fabric and Jersey cattle take  their names from the island.</p><p>Jersey Breed of small, short-horned dairy cattle that originated on Jer�  sey in the English Channel. They are believed to have descended from  French cattle. Jerseys are usually fawn- or cream-coulored, but darker  shades are common. They were introduced in large numbers into England  c. 1811 and into the U.S. in 1850. Adaptable to a wide range of condi�  tions, the Jersey is found worldwide. Its milk is remarkably high in but-  terfat, and it is an important breed wherever butter is produced (including  New Zealand and Denmark).</p><p>Jersey City City (pop., 2000: 240,055), northeastern New Jersey, U.S.  It lies opposite New York City. First settled by Dutch trappers (1618) and  known as Paulus Hook, it was purchased from the Delaware Indians and  established as a permanent settlement by 1660. In 1779, during the Ameri�  can Revolution, Henry Lee won a victory there over the British. Renamed  Jersey City in 1820, it is a manufacturing centre.</p><p>Jerusalem Hebrew Yerushalayim \ye- 1 rii-sha- , ll-im\ Arabic  Al-Quds \al-'kiits\ City (pop., 2005 est.: 704,900), capital of Israel (see  below). Located in the heart of historic Palestine, it is nestled between the  West Bank and Israel. The Old City is a typical walled Middle Eastern  enclosure; the modern city is an urban agglomeration of high-rises and  housing complexes. It is holy to Judaism as the site of the Temple of Jerus�  alem, to Christianity because of its association with Jesus, and to Islam  because of its connection with the Mi'raj (the Prophet Muhammad�s  ascension to heaven). Jewish shrines include the Western Wall. Islamic  holy places include the Dome of the Rock. In 1000 bc David made it the  capital of Israel. Razed by the Babylonians in the 6th century bc, it there�  after enjoyed only brief periods of independence. The Romans devastated  it in the 1st and 2nd centuries ad, banishing the Jewish population. From  638 it was ruled by various Muslim dynasties, except for short periods  during the Crusades when it was controlled by Christians. Rule by the  Ottoman Empire ended in 1917, and the city became the capital of the Brit�  ish mandate of Palestine. It was thereafter the subject of competing Zion�  ist and Palestinian national aspirations. Israel claimed the city as its capital  after the Arab-Israeli War in 1948 and took the entire city during the Six-  Day War of 1967. Its status as Israel�s capital has remained a point of  contention: official recognition by the international community has largely  been withheld pending final settlement of regional territorial rights.</p><p>Jerusalem, Council of Conference of the Christian Apostles at Jerus�  alem c. ad 50, which decreed that Gentile Christians did not have to  observe the Mosaic law of the Jews. It was occasioned by the controversy  over whether circumcision was necessary for Gentile converts to Chris�  tianity. Led by Sts. Peter the Apostle and James, the council decided the  issue in favor of St. Paul and the Gentile Christians, thus helping to sepa�  rate early Christianity from Judaism.</p><p>Jerusalem, Temple of Either of two temples that were at the centre  of worship and national identity in ancient Israel. When David captured  Jerusalem, he moved the Ark of the Covenant there. As the site for a  temple, he selected Mount Moriah, or the Temple Mount, where it was  believed that Abraham had built his altar to sacrifice Isaac. The First  Temple was constructed under David�s son Solomon and was completed  in 957 bc. It contained three rooms: a vestibule, the main room for reli�  gious services, and the Holy of Holies. From the time of Josiah, it was  designated as the only place for sacrifice in Judah. It was destroyed dur�  ing the Babylonian conquest in 586 bc. When the Jews returned from exile  in 538, they built the Second Temple (finished 515). Its desecration by  Antiochus IV in 167 bc set off the Maccabees� revolt, after which it was  cleansed and rededicated. In 54 bc Marcus Licinius Crassus plundered the  Temple. It was rebuilt and enlarged by Herod the Great; construction  lasted 46 years. The Jewish rebellion in ad 66 led to its destruction by  Roman legions in ad 70. All that remains is part of the Western Wall, a  site of pilgrimage. The Temple Mount is now occupied by a Muslim  mosque, Al-Aqsa, and the Dome of the Rock.</p><p>Jerusalem artichoke Sunflower {Helianthus tuberosus ) native to  North America and grown for its edible tubers. The aboveground part of  the plant is a coarse, usually multibranched, frost-tender perennial, 7-10  ft (2-3 m) tall. The numerous showy flower heads have yellow ray flow�  ers and yellow, brownish, or purplish disk flowers. The underground  tubers vary in shape, size, and colour. Jerusalem artichoke is popular as  a cooked vegetable in Europe and has long been cultivated in France as  livestock feed. In the U.S. it is rarely cultivated.</p><p>Jervis Bay Inlet of the Tasman Sea, southeastern New South Wales,  Australia. It is about 10 mi (16 km) long and 6 mi (10 km) wide. It was  discovered in 1770 and named Long Nose by Capt. James Cook, but in  1791 it was renamed for Adm. John Jervis. In 1915 it was transferred  from the jurisdiction of New South Wales to the Australian Common�  wealth to provide the Australian Capital Territory with access to the sea.

First organized by St. Ignatius of Loyola in  1534 at the University of Paris, the order was approved by Pope Paul III  in 1540. It discontinued many practices of medieval religious life, such  as obligatory penances and fasts and a common uniform, and instead  focused on military-style mobility and adaptability. Its organization was  characterized by centralized authority, probation lasting many years  before final vows, and special obedience to the pope. The Jesuits served  as a preaching, teaching, and missionary society, actively promoting the  Counter-Reformation, and by the time of Ignatius�s death in 1556 their  efforts were already worldwide. The success of their enterprise and their  championship of the pope earned them much hostility from both religious  and political foes. Under pressure from France, Spain, and Portugal, Pope  Clement XIV abolished the order in 1773, but it was restored by Pius VII  in 1814. The Jesuits have since become the largest male religious order.</p><p>Jesuit Estates Controversy Canadian dispute between Protestants  and Roman Catholics after reestablishment of the Jesuit order. After the  pope suppressed the Jesuits in 1773, their landholdings in Canada were  transferred to the British government. The pope restored the order in 1814,  and some Jesuits returned to Canada in 1842. Restitution for their land  was discussed, and the Jesuits� Estates Act (1888) gave $400,000 in com�  pensation.</p><p>Jesus In Christianity, the son of God and the second person of the Holy  Trinity. Christian doctrine holds that by his crucifixion and resurrection he  paid for the sins of all mankind. His life and ministry are recounted in  the four Gospels of the New Testament. He was born a Jew in Bethlehem  before the death of Herod the Great in 4 bc, and he died while Pontius  Pilate was Roman governor of Judaea (ad 28-30). His mother, Mary, was  married to Joseph, a carpenter of Nazareth (see St. Joseph). Of his child�  hood after the birth narratives in Matthew and Luke, nothing is known,  except for one visit to Jerusalem with his parents. He began his ministry  about age 30, becoming a preacher, teacher, and healer. He gathered dis�  ciples in the region of Galilee, including the 12 Apostles, and preached the  imminent arrival of the Kingdom of God. His moral teachings, outlined in  the Sermon on the Mount, and his reported miracles won him a growing  number of followers, who believed that he was the promised MESSIAH. On  Passover he entered Jerusalem on a donkey, where he shared the Last  Supper with his disciples and was betrayed to the Roman authorities by  Judas Iscariot. Arrested and tried, he was condemned to death as a politi�  cal agitator and was crucified and buried. Three days later visitors to his  tomb found it empty. According to the Gospels, he appeared several times  to his disciples before ascending into heaven.</p><p>jet engine Any of a class of internal-combustion engines that propel air�  craft by means of the rearward discharge of a jet of fluid, usually hot  exhaust gases generated by burning fuel with air drawn in from the atmo�  sphere. Jets rely on the third of Newton's laws of motion (action and reac�  tion are equal and opposite). The first jet-powered airplane was introduced  in 1939 in Germany. The jet engine, consisting of a gas-turbine system,  significantly simplified propulsion and enabled substantial increases in  aircraft speed, size, and operating altitudes. Modem types of jet engines  include turbojets, turbofans, turboprops, turboshafts, and ramjets. See air�  plane. See also drag; gasoline engine; lift.</p><p>jet lag Period of adjustment of biological rhythm after moving from one  time zone to another, experienced as fatigue and lowered efficiency. It  reflects a delay in the synchronization of changes in the level of blood  cortisol, the major steroid produced by the adrenal cortex (see adrenal  gland), with the local day-night cycle. Duration and severity depend on  how much distance is covered in how little time. Travel by jet, after which  the phenomenon may persist for some days, first made it noticeable,  accounting for the name.</p><p>jet stream Any of several long, narrow, high-speed air currents that  flow eastward in a generally horizontal zone in the stratosphere or upper  troposphere. Jet streams are characterized by wind motions that generate  strong vertical shearing action, considered largely responsible for the  clear-air turbulence experienced by aircraft. They also have an effect on  weather patterns. Jet streams circle the Earth in meandering paths, shift�</p><p>ing position as well as speed with the seasons. In the winter they are nearer  the Equator and their speeds are higher than in the summer. There are  often two, sometimes three, jet-stream systems in each hemisphere.</p><p>Jew Any person whose religion is Judaism. In a wider sense the term  refers to any member of a worldwide ethnic and cultural group descended  from the ancient Hebrews who traditionally practiced the Jewish religion.  The Hebrew term Yehudi, translated as Judaeus in Latin and Jew in  English, originally referred to a member of the tribe of Judah. In Jewish  tradition, any child born of a Jewish mother is considered a Jew; in Reform  Judaism a child is considered a Jew if either parent is Jewish.</p><p>Jewel Cave National Monument National monument, southwest�  ern South Dakota, U.S. Established in 1908, it occupies an area of 2 sq mi  (5 sq km).

Jewelry evolved  from shells, animal teeth, and other objects used as adornment in prehis�  toric times. Over the centuries it came to be a sign of social or religious  rank. In Renaissance Italy, jewelry making reached the status of a fine art;  many Italian sculptors trained as goldsmiths. From the 17th century the  decorative function of jewelry again came to the fore, overshadowing its  symbolic significance. By the 19th century, industrialization brought jew�  elry within the reach of the middle class. Firms opened by jewelers such  as Carl Faberge and Louis Comfort Tiffany achieved great success by mak�  ing fine jewelry for the wealthy.</p><p>Jewett, (Theodora) Sarah Orne (b.

In the Middle Ages, this  meant any methodical and disciplined thought pursued by Jews, whether  on specifically Judaic themes or not; in modern times, philosophers who  do not discuss Judaism are not ordinarily classified as Jewish philoso�  phers. Philosophy arose in Judaism under Greek influence, though a philo�  sophical approach may be discerned in early Jewish religious works  apparently uninfluenced by the Greeks. From the Bible, the books of Job  and Ecclesiastes were favourite works of medieval philosophers; the book  of Proverbs introduces the concept of Wisdom ( Hokhma ), which was to  have primordial significance for Jewish philosophical thought; and the  Wisdom of Solomon had considerable influence on Christian theology.  Major figures of Jewish philosophy include Philo Judaeus, Saadia ben  Joseph, Moses Maimonides, and Benedict de Spinoza.</p><p>Jezebel Yje-za-,bel\ (d. c. 843 bc) In the Hebrew scriptures, the wife of  King Ahab of Israel. The daughter of the priest-king Ethbaal of Tyre and  Sidon, she persuaded Ahab to introduce the worship of the Tyrian god  Baal-Melkart into Israel, thus interfering with the exclusive worship of  Yahweh. The book of 1 Kings tells how she was opposed by Elijah. After  Ahab�s death Jezebel�s son Jehoram became king of Israel, but Elisha  encouraged a general, Jehu, to revolt. Jehoram was killed, and Jezebel  was thrown from a window to her death. Dogs consumed most of her  body, fulfilling a prophecy by Elijah. In history and literature she became  the archetype of the wicked woman.</p><p>Jhabvala Vjab-va-b\, Ruth Prawer orig. Ruth Prawer (b. May</p><p>7, 1927, Cologne, Ger.)

He taught Roman  law at Giessen (1852-68), at Gottingen (from 1872), and at four other  universities (including the University of Vienna) for briefer periods. He  examined the relationship between law and social change in The Spirit of  Roman Law (1852-65) and between individual and social interests in Law  as a Means to an End (1877-83). He maintained that the purpose of law  is to protect individual and societal interests by coordinating them and  thus minimizing occasions for conflict. He is sometimes called the father  of sociological jurisprudence.</p><p>Jia Xian (fl. c. 1050, China) Mathematician and astronomer active at  the beginning of the greatest period of traditional Chinese mathematics.  He held a relatively low military office during the reign (1022/23-1063/  64) of Emperor Renzong of the Song dynasty. He was a pupil of math�  ematician and astronomer Chu Yan, who contributed to the revision of the  Chongtian calendar in 1023, and he served in the Imperial Astronomical  Bureau. Jia�s name was mainly quoted in connection with his method of  extracting roots (solutions) of polynomials of degree higher than three and  with the related Jia Xian triangle, which contains the binomial coefficients  for equations up to the sixth degree (see binomial theorem).

He started his career in Shang�  hai as an engineer, received training abroad, and gradually rose through  the ranks of the CCR He was named mayor of Shanghai in 1985 and  chairman of China�s Central Military Commission in 1989. It is thought  that Jiang was a compromise candidate to replace Zhao Ziyang as gen�  eral secretary in June 1989 following the Tiananmen Square incident. He  combined a commitment to continued free-market reform with a deter�  mination to preserve the CCP�s monopoly on political power.

With an area of 39,600 sq mi (102,600 sq km), it is one  of the smallest and most densely populated provinces of China, and it is  also one of the wealthiest. Its capital is Nanjing (Nanking). It occupies a  wide alluvial plain that is divided into two sections by the estuary of the  Yangtze River (Chang Jiang). Once a part of the ancient state of Wu, the  region was part of the Nanjing province under the Ming dynasty (1368�  1644). It became a separate province in 1667 and served as the headquar�  ters (1853-64) for the Taiping Rebellion. It was an important base for  China�s Nationalist Party, which made Nanjing the nation�s capital from  1928 to 1937 and again from 1946 to 1949. The province was occupied  by Japan during the Sino-Japanese War (1937-45) and came under com�  munist control in 1949.

The term, taken from a minstrel-show rou�  tine, became a derogatory epithet for African Americans. After Reconstruc�  tion, Southern legislatures passed laws requiring segregation of whites and  �persons of colour� on public transportation. These later extended to  schools, restaurants, and other public places. In 1954 the U.S. Supreme  Court declared segregation in public schools unconstitutional in Brown v.

The dynasty had two distinct phases: the  Western Jin (ad 265-317) and the Eastern Jin (ad 317^420). The latter is  considered one of the Six Dynasties that ruled China between the fall of  the Han (ad 220) and the establishment of the Sui (581). China was  reunited under Sima Yan (Ssu-ma Yen), first of the Jin emperors, but after  his death the empire rapidly crumbled. The XlONGNU nomads of the north  overran the Jin capital of Luoyang and later defeated the Jin again at  Chang'AN. For the next two centuries China was divided into two soci�  eties, northern (plagued by barbarian invasions) and southern. The East�  ern Jin, founded by another Sima prince at Nanjing, suffered revolts, court  intrigues, and frontier wars, but also saw the flourishing of Buddhism in  China and the birth of China�s first great painter, Gu Kaizhi (344-4067).

Nearby Mount Tai was one of  China�s greatest holy mountains; many Buddhist cave temples were built  in the hills south of the city in the 4th-7th centuries ad. It was made the  capital of Shandong under the Ming dynasty (1368-1644). Opened to for�  eign commerce in 1904, it developed further after becoming a railroad  junction in 1912. It is now a major administrative and industrial centre  and Shandong�s chief cultural centre, with agricultural, medical, and engi�  neering colleges and a large university (1926).</p><p>jingxi or ching-hsi, also called Beijing opera or Peking opera  Chinese "opera of the capital" Traditional Chinese theatre, origi�  nally devised in 1790 as part of the Qianlong emperor�s birthday celebra�  tion. Highly conventionalized and symbolic, it combines orchestral music,  speech, song, dance, and acrobatics. The performers enact dramas based  on historical epics, legend, and myth. The characters� roles and social  ranks are conveyed through elaborate costumes and stylized makeup. The  actor Mei Lanfang brought its influence to the West through his tours of  Russia and the U.S. in the 1930s. Jingxi traditionally employed an all�  male cast with female impersonators, but in the late 20th century it  expanded its scope to admit female actors.</p><p>jinja In the Shinto religion, a place where a god is enshrined or to which  it is summoned.

After  returning to India, he practiced law and was elected to India�s Imperial  Legislative Council in 1910. Committed to home rule for India and to  maintaining Hindu-Muslim unity, he joined the Muslim League in 1913 and  worked to ensure its collaboration with the Indian National Congress. He  was opposed to Mohandas K. Gandhi�s noncooperation movement and  withdrew from the Congress. In the late 1920s and early �30s, he was  seen as too moderate by some Muslims but too Muslim by the Congress  Party. From 1937, when the Congress Party refused to form coalition  governments with the Muslim League in the provinces, Jinnah began to  work for the partitioning of India and on creating a Muslim state. Paki�  stan emerged as an independent country in 1947, and Jinnah became its  first head of state. He died in 1948, revered as the father of the nation.</p><p>jinni or genie plural jinn In Arabic mythology, any of the supernatu�  ral spirits less powerful than angels or devils.

A prodigy, he began study as a child in Pest,  continuing later in Vienna and Leipzig, where he was associated with Felix  Mendelssohn. He was concertmaster at Weimar under Franz Liszt (1850-  52), but their tastes in music diverged radically. He became close to  Johannes Brahms, who sought Joachim�s advice about his violin concerto.  Joachim wrote cadenzas that are still used for a number of concertos.

He retired into the  mountains to follow a contemplative life in 1191, and in 1196 he founded  the order of San Giovanni in Fiore. His Book of Harmony of the New and  Old Testaments outlined a theory of history and traced correspondences in  the Old and New Testaments. In his Exposition of the Apocalypse he exam�  ined the symbols of the Antichrist, and in Psaltery of Ten Strings he  expounded his doctrine of the Holy Trinity.

Suspected of her husband�s murder, she fled  to Avignon (1348). She sold Avignon to the papacy in return for being  cleared of the crime, then went back to Naples in 1352. She recognized  the antipope Clement VII in 1378, and Pope Urban VI crowned Charles  of Durazzo king of Naples in 1381. When Charles captured Naples, he  imprisoned Joan and had her killed.</p><p>Joan, Pope Legendary female pontiff who supposedly reigned, as Pope  John VIII, for about 25 months from 855 to 858.

After acquiring great learn�  ing she moved to Rome, where she became cardinal and then pope. In the  earliest version of the story, she was pregnant at the time of her election  and gave birth during the procession to the Lateran, whereupon she was  dragged out of Rome and stoned to death.

Michael, Cathe�  rine, and Margaret. When she was about 16, her voices began urging her</p><p>to aid France�s Dauphin (crown prince) and save France from the English  attempt at conquest in the Hundred Years' War. Dressed in men�s clothes,  she visited the Dauphin and convinced him, his advisers, and the church  authorities to support her. With her inspiring conviction, she rallied the  French troops and raised the English siege of Orleans in 1429. She soon  defeated the English again at Patay. The Dauphin was crowned king at  Reims as Charles VII, with Joan beside him. Her siege of Paris was unsuc�  cessful, and in 1430 she was captured by the Burgundians and sold to the  English. Abandoned by Charles, she was turned over to the ecclesiastical  court at Rouen, controlled by French clerics who supported the English,  and tried for witchcraft and heresy (1431). She fiercely defended herself  but finally recanted and was sentenced to life imprisonment; when she  again asserted that she had been divinely inspired, she was burned at the  stake. She was not canonized until 1920.</p><p>Job Vjob\ Central character of the Book of Job in the Old Testament,  known for his faithfulness to God despite his many afflictions. At the  beginning.

Soon  Job is desolate, covered with boils, his wealth gone and his family dead.  Three friends arrive to comfort him; he disputes with them, denying he  has done anything to deserve this misery but maintaining his faith in God.  At the end, in a confrontation with God, the power and mystery of the  deity are memorably reasserted, but the problem of why the innocent suf�  fer is left unresolved.

In 1959 he and Luis  Bonfa composed the score for the film Black Orpheus, and his worldwide  success soon followed. He transformed samba music into bossa nova  (�new wrinkle� or �new wave�), a fusion of understated samba pulse  (quiet percussion, unamplified guitars playing subtly complex rhythms),  gentle singing, and the melodic and sophisticated harmonies of cool jazz;  the style found a long-lasting niche in popular music. He collaborated with  Frank Sinatra, Stan Getz, and Astrud Gilberto, and he also composed clas�  sical works and film scores. His more than 400 songs include �One-Note  Samba,� �Meditation,� and �The Girl from Ipanema.�</p><p>Jobs, Steven Paul (b. Feb. 24, 1955, San Francisco, Cal., U.S.) U.S.  businessman. Adopted in infancy, he grew up in Los Altos. He dropped  out of Reed College and went to work for Atari Corp. designing video  games. In 1976 he cofounded (with Stephen Wozniak) Apple Computer,  Inc. The first Apple computer, created when Jobs was only 21, changed  the public�s idea of a computer from a huge machine for scientific use to  a home appliance that could be used by anyone. Apple�s Macintosh com�  puter, which appeared in 1984, introduced a graphical user interface and  mouse technology that became the standard for all applications interfaces.  In 1980 Apple became a public corporation, and Jobs became the com�  pany�s chairman. Management conflicts led him to leave Apple in 1985  to form NeXT Computer Inc., but he returned to Apple in 1996 and  became CEO in 1997. The striking new iMac computer (1998) revived  the company�s flagging fortunes.</p><p>Jocho \'j6-,cho\ (d. 1057, Japan) Japanese Buddhist sculptor. The son  and pupil of a sculptor, he worked primarily for the Fujiwara family. He  was awarded unprecedented honours for sculptures executed for Kyoto�s  Hojo Temple and for the Fujiwara family temple in Nara. He was instru�  mental in improving the social standing of Buddhist sculptors by orga�  nizing a guild, and he perfected the so-called kiyoseho, or joined-wood  technique. His only extant work is a carved Amida (Buddha) figure (c.  1053) in the Byodo Temple at Uji.</p><p>Joel Second of the 12 Minor Prophets in the Hebrew scriptures, author  of the book of Joel. (His prophecy is part of a larger book, The Twelve,  in the Jewish canon.) He lived sometime during the period of the Second  Temple of Jerusalem (516 bc-ad 70), but nothing is known of his life. He  opens his prophecy by describing a plague of locusts, an allegory of the  disasters to come upon a faithless people. His message is simple: salva�  tion will come to Judah only when the people truly turn to Yahweh. The  end of the book looks forward to the final days, when all Israel will share  in the knowledge of God.</p><p>Joffre VzhofrA, Joseph (-Jacques-Cesaire) (b. Jan. 12, 1852,  Rivesaltes, France�d.

As commander  in chief (1915-16), he ordered the  French armies to burst through the  German positions, at ruinous cost.</p><p>His prestige waned, and, because of  the lack of French preparation for the  Battle of Verdun (1916), he was  stripped of his direct command and  resigned.

He was the son of an Afghan  father and an Italian-born mother. He studied dance in Seattle and later  in New York, opened a ballet school in 1953, and in 1954 formed the first  of several groups. In 1956 he founded the Robert Joffrey (later simply  Joffrey) Ballet with Gerald Arpino (b. 1928). The company gained inter�  national fame and toured widely. In 1965 it became affiliated with the  New York City Center. Joffrey�s ballets include Persephone (1952),  Astarte (1967), Remembrances (1973), and Postcards (1980). After Jof�  frey�s death, Arpino became director; in 1995 he moved the company to  Chicago, renaming it the Joffrey Ballet of Chicago.</p><p>Jogan \'j6-,gan\ style Japanese sculptural style of the early Heian period,  seen primarily but not exclusively in Buddhist sculptures. The massive  figures, carved from single blocks of wood, are columnar, erect, and sym�  metrical and have large round faces, large lips, wide noses, and wide eyes,  almost geometrically simplified. The drapery, composed of alternating  series of small and large waves, is its most distinguishing feature. The  technique was first seen on the drapery of the colossal image of the Bud�  dha at Barman, Afg.; Chinese and Japanese pilgrims brought back holy  images and used them as prototypes for their own sacred images.</p><p>jogging Aerobic exercise involving running at an easy pace. Jogging  (1967) by Bill Bowerman and W.E. Harris boosted jogging�s popularity  for fitness, weight loss, and stress relief. Many medical authorities endorse  jogging, but others warn of risks to feet, shins, knees, and backs. Jogging  only every other day, warming up properly, and using well-designed shoes  and proper technique can reduce risks.</p><p>Johanan ben Zakkai yjo-'ha-non-ben-'za-ka-.lV (fl. 1st century ad)  Palestinian Jewish sage. A leading representative of the Pharisees, he  helped preserve and develop Judaism in the years after the destruction of  the Second Temple of Jerusalem (ad 70). He is said to have been smuggled  out of the besieged city in a coffin and to have visited the Roman camp  and persuaded the future emperor Vespasian to allow him to set up an  academy at Jamnia near the Judaean coast. He established an authorita�  tive rabbinic body there and was revered as a great teacher and scholar.</p><p>Johannesburg City (pop., 2001: metro, area, 3,225,810), northeastern  South Africa. The capital of Gauteng province and one of the country�s  largest cities, it bestrides a highland region called the Witwatersrand. It  was founded in 1886 after the discovery of gold nearby and was occu�  pied by the British during the South African War in 1900. It was a legally  segregated city until 1991; non whites were restricted to living in outly�  ing areas called townships, including Soweto. Greater Johannesburg  extends more than 600 sq mi (1,600 sq km) and includes more than 500  suburbs and townships. It is a leading industrial and financial centre.

Feb. 3, 1857, Copenhagen,  Den.�d. Nov. 11, 1927, Copenhagen) Danish botanist and geneticist. He  supported Hugo de Vries�s discovery that variation in genotype can occur  by mutation; the new character, while independent of natural selection in</p><p>its initial occurrence, is then subject to natural selection. Johannsen�s Ele�  ments of Heredity (1909) became an influential text, and his terms phe�  notype and genotype are now a part of the language of genetics.</p><p>Johansson, (Per) Christian (b.

He was engaged at  the Imperial Russian Ballet in 1841. In his prime his innate nobility and  grace were unsurpassed. In 1860 he turned his attention to teaching at the  Imperial Ballet School. Over the next four decades he brought a new pol�  ish to the Russian style, providing it with a firm base in the French method  that he had learned from Bournonville.</p><p>John known as John Lackland (b. Dec. 24, 1167, Oxford, Eng.�d.  Oct. 18/19, 1216, Newark, Nottinghamshire) King of England (1199�  1216). The youngest son of Henry II, he joined his brother Richard (later  Richard I) in a rebellion against Henry (1189). John became lord of Ire�  land, and, when Richard was imprisoned in Germany on his way back  from the Third Crusade, he tried to seize control of England (1193). On  Richard�s return, John was banished (1194), but the two were later rec�  onciled. Crowned king in 1199, John lost Normandy (1204) and most of  his other French lands in a war with Philip II (Philip Augustus). After Inno�  cent III excommunicated him for refusing to recognize Stephen Langton as  archbishop of Canterbury, John was obliged to declare England a fief of  the Holy See (1213). He launched a military campaign against France in  1214 but made no lasting gains. His heavy taxes and aggressive assertion  of feudal privileges led to the outbreak of civil war (1215). The barons  forced him to sign the Magna Carta, but the civil war continued until his  death.</p><p>John or John de Balliol (b. c. 1250�d. April 1313, Chateau Gal-  liard, Normandy, Fr.) King of Scotland (1292-96). He was one of 13  claimants to the throne but won by primogeniture. John paid homage to  Edward 1 of England but soon refused his request for military aid in Gas�  cony and instead signed a treaty with the French. When Edward invaded  Gascony in 1296, the Scots raided northern England. Within months  Edward* s army had captured strategic castles in Scotland, and John was  forced to resign his kingdom to Edward. He was held in the Tower of  London until 1299.</p><p>John I Portuguese Joao known as John of Aviz \a-'vezh\ (b. April  11, 1357, Lisbon�d. Aug. 14, 1433, Lisbon) King of Portugal (1385�  1433) and founder of the Aviz dynasty. The illegitimate son of Pedro I,  he was elected king in 1385 despite the rivalry of Castilian candidates.  He fought off a Castilian invasion (1385) and preserved Portugal�s inde�  pendence. He made an alliance with England (1386), but a joint invasion  of Leon was unsuccessful. John signed a 10-year truce with Castile in  1389, but frontier warfare was intermittent until 1411. He and his sons  (including the youngest, later Henry the Navigator) captured Ceuta in  Morocco in 1415, thus beginning the era of Portuguese expansion.</p><p>John II French Jean known as John the Good (b. April 16, 1319,  near Le Mans, France�d. April 8, 1364, London, Eng.) King of France  (1350-64). At odds with England and Navarre, he tried to make peace  with the Navarrese king Charles II, then had him imprisoned in 1356.  Edward the Black Prince, son of Edward III of England, led an invasion of  southern France, defeating and capturing John at the Battle of Poitiers  (1356). John was forced to sign the treaties of Bretigny and Calais (1360),  which fixed an extravagant ransom and surrendered most of southwest�  ern France to the English. See also Hundred Years' War.</p><p>John II Comnenus \kam-'ne-nos\ (b. Sept. 13, 1087�d. April 8,1143)  Byzantine emperor (1118�43). The son of Alexius I Comnenus, he made it  his mission to reconquer Byzantine territory lost to the Arabs, Turks, and  Crusaders. He cancelled Venetian trading privileges in the empire but was  forced to restore them after the Venetians launched a fleet to retaliate  against him. John allied himself with the German emperor against Roger  II of Sicily (1130). He reconquered Cilicia (1137) and won homage from  Antioch, but he failed to defeat the Syrian Turks.</p><p>John III Ducas Vatatzes Vdyu-kos-vo-'tat-sezV (b. c. 1193�d.

Two  years later he triumphed over Latin forces loyal to his rivals and gained  control of Asia Minor. He allied with Ivan Asen II against Epirus (1230)  and besieged Constantinople (1235), prompting Asen to go to war with  him (1235-37).

June 17,</p><p>1696, Wilanow) Elective king of  Poland (1674-96). Named com�  mander in chief of the Polish army  (1668), he distinguished himself by  victories over the Cossacks and  Turks. His reputation was so great  that he was elected king in preference  to the Habsburgs� candidate. In 1683  he concluded a treaty with Emperor  Leopold I against the Ottoman Turks.</p><p>When a Turkish army approached  Vienna later that year, he rushed there  with troops, took command of the  entire relief force, and achieved a  brilliant victory, briefly restoring the  kingdom of Poland-Lithuania to  greatness for the last time. He was  unsuccessful in a Hungarian cam�  paign (1683-91) to liberate Moldavia  and Walachia from Ottoman rule.</p><p>Later rebellion within his own family, with nobles fighting each other  rather than the Turks, led finally to Poland�s downfall in the 18th century.</p><p>John V Palaeologus \,pa-le-'a-l3-g3s\ (b.

The son of Andronicus III Palaeologus, he inherited the throne  at age nine; John VI Cantacuzenus served as his regent and coemperor  (1347-54). After the Ottoman Turks gained control of Galliopoli and  threatened Constantinople, John V appealed to the West for help, propos�  ing to end the schism between the Byzantine and Latin churches. Impov�  erished by war, he was detained as a debtor when he visited Venice (1369).  In 1371 he was forced to recognize Turkish overlords, who later helped  him to regain the throne (1379) after he was deposed by his son.</p><p>John VI Cantacuzenus \ l kan-t3-kyu- , ze-nos\ (b. c. 1292�d. June 15,  1383, Mistra, Byzantine Empire) Byzantine emperor (1347-54). As chief  adviser (1328-41) to Andronicus III Paiaeologus, he directed both domes�  tic and foreign policy. He fought to serve as regent for the young John V  Palaeologus, triumphing over John�s mother, Anna of Savoy, only by  enlisting Turkish aid. From 1347 he ruled as coemperor with John V, but  in 1354 he crowned his own son coemperor. With Venetian aid, John V  then forced him to abdicate, and Cantacuzenus retired to a monastery,  where he wrote his memoirs.</p><p>John VIII Palaeologus \,pa-le-'a-l3-g9s\ (b. Dec. 17/18, 1392�d.  Oct. 31, 1448, Constantinople) Byzantine emperor (1421-48). The son of  Manuel II Palaeologus, he was crowned coemperor with his father in 1408  and took effective control of the empire in 1421. He became sole emperor  after his father�s death in 1425. Of the diminished and fragmented empire,  he ruled only Constantinople and the surrounding area. The city was  besieged by the Ottoman Turks (1422), and, when Thessaloniki fell to  Turkish forces (1430), John appealed to the West for help. He united the  Byzantine and Latin churches (1439), but joint efforts against the Turks  failed, and the Byzantines refused to submit to the pope. John died amid  intrigues over succession.</p><p>John XXII orig. Jacques Duese (b. Cahors, France�d. Dec. 4,1334,  Avignon) Second Avignon pope (1316-34). The successor to Clement V,  he established the papal court at Avignon on a permanent basis (see Avi�  gnon papacy). He condemned the Spiritual Franciscans� interpretation of  the poverty of Christ and his Apostles and upheld papal authority over  imperial elections against the opposition of the emperor, Louis IV. When  John excommunicated Louis, the emperor retaliated by declaring him  deposed (1328) and sponsoring the election of an antipope. John�s views  on the beatific vision provoked accusations of heresy (1331-32). He is  remembered for centralizing church administration and adding to the body  of canon law.</p><p>John XXIII orig. Angelo Giuseppe Roncalli (b. Nov. 25, 1881,  Sotto il Monte, Italy�d. June 3, 1963, Rome; beatified Sept. 3, 2000;  feast day October 11) Pope (1958-63). He studied theology in Rome, was</p><p>ordained a priest in 1904, and held a  variety of church offices. In 1944 he  was named papal nuncio to newly  liberated France, where he success�  fully revived sympathy for the Vati�  can. Made a cardinal in 1953, he was  elected pope after the death of Pius XII  (1939-58). Because of his advanced  age, he was expected to be little more  than a caretaker in the office, but  instead he became the major reform�  ing pope of the century. Eager to lead  the church into the modem era, he  called the Second Vatican Council in  1962, inviting Eastern Orthodox and  Protestant observers to join Catholic  delegates. He also sought to repair  relations with the Jews. The council  went on to make major reforms in  Catholic liturgy and administration,  though John died before its conclusion. An energetic advocate of world  peace, he was one of the most popular popes in history. In 2000 he was  beatified by John Paul II (1978-2005).</p><p>John, Augustus (Edwin) (b.

By the age of 20 he had won a repu�  tation for his brilliant drawing technique. A colourful personality, he  roamed Britain, living with Roma and learning their customs and lan�  guage; the painting Encampment on Dartmoor (1906) is based on these  experiences. He is best known for his portraits of leading European per�  sonalities, including those of James Joyce and George Bernard Shaw.</p><p>John, Sir Elton (Hercules) orig.

John served as a commander in the Hun�  dred Years� War against France, then returned to become an important  influence in his father�s last years as king and in the reign of his nephew  Richard II. Through his first wife, John acquired the duchy of Lancaster  in 1362, and he was the immediate ancestor of the three 15th-century  monarchs of the house of Lancaster: Henry IV, Henry V, and Henry VI.</p><p>John of Paris or Jean de Paris Vzha n -d3-pa-'re\ or John the  Deaf or John Quidort \ke-'dor\ (b. c. 1255, Paris, France�d.

He served as secretary to Theobald and St. Thomas Becket, archbishops  of Canterbury. He wrote Historiapontificalis (c. 1163) and the Policraticus  and the Metalogicon (both 1159) His defense of Becket and of ecclesias�  tical liberties led Henry II to exile him to France (1163). He returned to  England after the reconciliation of Henry and Becket and was in Canter�  bury Cathedral when Becket was assassinated.

He  became a Carmelite monk at Medina del Campo and was ordained a priest  in 1567. Joining St. Teresa of Avila in her effort to restore the Carmelites  to their original austerity, he cofounded the Discalced Carmelite order in  1568. He opened the first Discalced Carmelite monastery at Duruelo a  year later, but reform caused friction within the order and led to his  imprisonment at Toledo. He escaped in 1578 and later won high office in  the order.

April 2, 2005, Vatican City) Pope (1978-2005), the bishop of  Rome and head of the Roman Catholic church, the first non-Italian pope in</p><p>455 years and the first ever from a  Slavic country. He studied for the  priesthood at an underground semi�  nary in Krakow during World War II  and was ordained in 1946. He earned  a doctorate in philosophy in Rome  (1948) and returned home to serve in  a parish, earning a second doctorate  (also 1948), in sacred theology, from  the Jagiellonian University. He  became archbishop of Krakow in  1964 and cardinal in 1967. Elected  pope after the 33-day pontificate of  John Paul I (b. 1912�-d. 1978), he  became known for his energy, cha�  risma, and intellect as well as for his  conservative theological views and  fervent anticommunism. In 1981  John Paul was shot in St. Peter�s  Square by a Turkish gunman, but he  recovered, resumed his work, and  forgave his would-be assassin. His  trips abroad attracted some of the largest crowds ever assembled. His non�  violent activism spurred movements that contributed to the peaceful dis�  solution of the Soviet Union in 1991. He championed economic and  political justice in developing nations. In naming 44 cardinals from five  continents (February 2001), John Paul reached out to cultures around the  world. He also canonized more saints, from more parts of the world, than  had any other pope. His ecumenical efforts, including meetings with Jew�  ish, Muslim, and Eastern Orthodox religious leaders, were widely praised,  but he often drew criticism for his traditionalist views on issues of gender  and sexuality. Although afflicted with Parkinson disease since the early  1990s, John Paul remained active and made a historic trip to Jerusalem in  March 2000, during which he sought to improve relations between the  Roman Catholic church and Jews.</p><p>John the Apostle, Saint or St. John the Evangelist or St.  John the Divine (fl. 1st century ad) One of the original Twelve Apostles  of Jesus, traditionally credited with writing the fourth Gospel and three  New Testament epistles.

John and his brother  James (see St. James) were among the first disciples called by Jesus, and  John appears to have held a position of authority in the early church after  the resurrection. Later accounts of his life are based on legend. He is said  to have died in Ephesus, and his tomb became a site of pilgrimage. John�s  Gospel, unlike the other three, presents a well-developed theological point  of view, on a level with the letters of St. Paul. After a prologue in which  he identifies God with the Word (Logos), he offers selected episodes from  Jesus� life and ministry. His explications of theological issues such as the  significance of the Son of God greatly influenced the development of  Christian doctrine.</p><p>John the Baptist, Saint (b. 1st century ad) Jewish prophet revered in  Christianity as the forerunner of Jesus. Sources for his life are the four  Gospels, the Acts of the Apostles, and the historian Josephus. His mother,  Elizabeth, was perhaps a relative of Mary; his father was the priest Zecha-  riah. As a young man John lived in the Judaean desert, either as a hermit  or as part of a Jewish monastic community such as the Essenes. He  attracted much public notice c. ad 28 as a prophet in the Jordan Valley.  He preached the imminent wrathful judgment of God and called on his  hearers to repent and be baptized. Jesus himself came to be baptized by  John and shortly afterward began his own mission. John was imprisoned  for criticizing the illegal marriage of Herod Antipas and was executed after  Herod�s stepdaughter, Salome, demanded his head as a reward for danc�  ing for the king�s guests.</p><p>John the Deaf See John of Paris  John the Good See John II (France)</p><p>Johns Hopkins University Private university in Baltimore, Mary�  land, U.S. It was founded as a graduate school in 1876 through an endow�  ment supplied by the Baltimore merchant Johns Hopkins (1795-1873).

May 15, 1930, Augusta, Ga., U.S.) U.S. painter,  sculptor, and printmaker. He began his career as a commercial artist, pro�  ducing displays for New York City shop windows. In 1958 he had his first  one-man exhibition, a rousing success. The paintings Johns went on to  produce depict commonplace, two-dimensional subjects such as flags,  targets, maps, numbers, and letters of the alphabet. He was able to raise  these objects to the level of icons through his paint handling and manipu�  lation of surface texture, which he obtained through the encaustic tech�  nique. In their willful and ironic banality and their rejection of emotional  expression, these early works were a radical departure from the then-  dominant Abstract Expressionist style. Johns�s unabashed depiction of com�  monplace emblems and objects was emulated by many Pop art artists.  From 1961 he began to attach real objects to his canvases. In the 1970s  he produced paintings composed of clusters of parallel lines that he called  �crosshatchings�; in the 1980s he experimented with figuration.</p><p>Johnson, Andrew (b. Dec. 29, 1808, Raleigh, N.C., U.S.�d. July  31, 1875, near Carter Station, Tenn.)</p><p>17th president of the U.S. (1865-69).</p><p>Born in poverty, he never attended  school, and he taught himself to read  and write. After a short apprentice�  ship as a tailor, he moved with his  family to Greeneville, Tenn., where  he opened his own tailor shop.</p><p>Before he was 21 he organized a  workingman�s party. Elected to the  state legislature (1835^-3), he  became a spokesman for small farm�  ers. He then served in the U.S. House  of Representatives (1843-53) and as  governor of Tennessee (1853-57).</p><p>Elected to the U.S. Senate (1857�</p><p>62), he opposed antislavery agita�  tion, but, in 1860, after the election  of Pres. Abraham Lincoln, he vehe�  mently rejected Southern secession,  a position he maintained even after  Tennessee seceded in 1861. During the American Civil War he was the  only Southern senator who refused to join the Confederacy. In 1862 he  was appointed military governor of Tennessee, then under Union control.  In 1864 he was selected to run for vice president with President Lincoln;  he assumed the presidency after Lincoln�s assassination. During Recon�  struction he favoured a moderate policy of readmitting former Confeder�  ate states to the Union with few provisions for reform or civil rights for  freedmen. In 1867, Johnson�s vetoes of legislation to establish a Freed-  men's Bureau and other civil rights measures angered moderate as well as  Radical Repubucans; in response, they united to pass the Tenure of Office  Act (1867), which forbade the president from removing civil officers  without senatorial consent. In 1868, in defiance of the act, Johnson dis�  missed secretary of war Edwin M. Stanton, an ally of the Radicals. The  House then voted to impeach the president�the first such occurrence in  U.S. history. In the subsequent Senate trial, the charges proved weak, and  the necessary two-thirds vote needed for conviction failed by one vote.  Johnson remained in office until 1869, but he had lost the ability to lead.  He returned to Tennessee, where he won reelection to the Senate shortly  before he died.</p><p>Johnson \'yon-s6n\, Eyvind (b. July 29, 1900, Svartbjornsbyn, near  Boden, Swed.�d. Aug. 25, 1976, Stockholm) Swedish novelist. He  endured a grim boyhood of hard labour. His early novels evince feelings  of frustration; Bobinack (1932) is an expose of the machinations of mod�  ern capitalism, and Rain at Daybreak (1933) is an attack on modern office  drudgery. Return to Ithaca (1946) and The Days of His Grace ( 1960) have  been widely translated. Johnson�s working-class novels experimented  with new forms and techniques; they also introduced new themes to Swed�  ish literature. He shared the 1974 Nobel Prize for Literature with Harry  Martinson.</p><p>Johnson, Frank (Minis), Jr. (b. Oct. 30, 1918, Halyeville, Ala.�d.  July 23, 1999, Montgomery, Ala.) U.S. judge. After graduating at the top  of his law-school class at the University of Alabama in 1943, he joined</p><p>the army, becoming an infantry lieutenant. After the war he returned to  Alabama to practice law. Appointed to the federal district court for middle  Alabama in 1955, he became widely known for his decisions in support  of the civil rights movement. In 1955 he voted with the majority to strike  down the bus-segregation law challenged by Rosa Parks, and in 1965 he  issued the order that allowed Martin Luther King, Jr., to lead a historic civil  rights march from Selma to Montgomery. He also ordered the desegre�  gation of various public facilities in Alabama, and he was the first fed�  eral judge to dictate legislative reapportionment. He served on the U.S.  District Court of Appeals from 1979 to 1992. In 1995 he received the  Presidential Medal of Freedom.</p><p>Johnson, Jack in full John Arthur Johnson (b. Mar. 31, 1878,  Galveston, Tex., U.S.�d. June 10,</p><p>1946, Raleigh, N.C.) U.S. boxer, the  first black to hold the title for the  heavyweight championship of the  world. Johnson�s career was marked  from the beginning by racial dis�  crimination; until his match with  Tommy Burns, he had a difficult time  getting fights. Johnson won the  heavyweight crown in 1908 by  knocking out Burns and kept it until  1915, when he was knocked out by  Jess Willard in 26 rounds. At the  height of his career, Johnson was  excoriated by the press for having twice married white women, and he  further offended white supremacists by knocking out former champion  James J. Jeffries, who was induced to come out of retirement as a �Great  White Hope.� In 1912 Johnson was convicted of violating the Mann Act  for transporting his wife-to-be across state lines before their marriage. He  was sentenced to a year in prison and was released on bond; he fled to  Canada, made his way to Europe, and was a fugitive for seven years. He  defended the championship three times in Paris before agreeing to fight  Willard in Havana, Cuba. Some observers thought that Johnson, mistak�  enly believing that the charge against him would be dropped if he yielded  the championship to a white man, deliberately lost to Willard. Johnson  surrendered to U.S. authorities in 1920 to serve a one-year sentence. From  1897 to 1928, Johnson had 114 bouts, winning 80, 45 by knockouts.</p><p>Johnson, James P(rice) (b. Feb. 1, 1894, New Brunswick, N.J.,  U.S.�d. Nov. 17, 1955, New York, N.Y.) U.S. pianist and composer, a  chief figure in the transition of ragtime to jazz. Johnson was performing  in saloons and at parties in New York City�s African American commu�  nity while still in his teens. He created the stride piano technique, a devel�  opment of ragtime that used two-beat left-hand rhythms to accompany  wide-ranging right-hand lines, in pieces such as �Carolina Shout� and  �Harlem Strut.� He composed and orchestrated music for stage revues,  including Keep Shufflin� (1928) with his student Fats Waller. His songs  include �The Charleston� (largely responsible for the 1920s dance craze)  and �Old Fashioned Love�; his large-scale works include the Harlem  Symphony (1932).</p><p>Johnson, James Weldon (b. June 17, 1871, Jacksonville, Fla.,  U.S.�d. June 26, 1938, Wiscasset, Maine) U.S. writer. He practiced law  in Florida before moving with his brother, the composer J. Rosamond  Johnson (1873-1954), to New York; there the two collaborated on some  200 songs for the Broadway stage. Johnson held diplomatic posts in Ven�  ezuela and Nicaragua and served as executive secretary of the NAACP  (1920-30). From 1930 he taught at Fisk University. His writings include  the novel Autobiography of an Ex-Colored Man (1912), Fifty Years and  Other Poems (1917), and his best-known work, God�s Trombones (1927),  a group of dialect sermons in verse. The brothers collaborated on the pio�  neering anthologies Book of American Negro Poetry (1922) and Ameri�  can Negro Spirituals (1925, 1926). Their most famous original song, �Lift  Every Voice and Sing,� became an anthem of the civil rights movement.</p><p>Johnson Vjan-son\, John H(arold) (b. Jan. 19, 1918, Arkansas City,  Ark., U.S.�d.

Aug. 27, 1908, Gillespie county,  Texas, U.S.�d. Jan. 22, 1973, San Antonio, Texas) 36th president of the  U.S. (1963-69). He taught school in Houston, Texas, before going to  Washington, D.C., in 1932 as a congressional aide. In Washington he was  befriended by Sam Rayburn, speaker of the House of Representatives, and  his political career blossomed. He won a seat in the U.S. House (1937�  49) as a supporter of the New Deal, which was under conservative attack.  His loyalty impressed Pres. Franklin D. Roosevelt, who made Johnson his  protege. He won election to the U.S. Senate in 1949 in a vicious cam�  paign that involved fraud on both sides. As Democratic whip (1951-55)  and majority leader (1955-61), he developed a talent for consensus build�  ing through methods both tactful and ruthless. He was largely responsible  for passage of the civil rights bills of 1957 and 1960, the first in the 20th  century. In 1960 he was elected vice president under John F. Kennedy; he  became president after Kennedy�s assassination in 1963. In his first few  months in office he won passage of the Civil Rights Act of 1964, the most  comprehensive and far-reaching legislation of its kind in American his�  tory. Later that year he announced his Great Society program of social-  welfare and civil rights legislation. His attention to domestic matters,  however, was diverted by the country�s escalating involvement in the  Vietnam War (see Gulf of Tonkin Resolution), which provoked large stu�  dent demonstrations and other protests, beginning in the late 1960s. Mean�  while, discontent and alienation among the young and racial minorities  increased as the promises of the Great Society failed to materialize. By  1967 Johnson�s popularity had declined steeply, and in early 1968 he  announced that he would not seek reelection. He retired to his Texas ranch.</p><p>Johnson, Magic orig. Earvin Johnson, Jr. (b. Aug. 14, 1959,  Lansing, Mich., U.S.) U.S. basketball player. He led Michigan State Uni�  versity to the collegiate championship in 1979 and led the NBA Los  Angeles Lakers to five championships in the 1980s. Standing 6 ft 9 in.  (2.06 m) tall, he was exceptionally tall for a point guard and was able to  use his size to rebound and score inside. However, he was best known for  his creative passing and expert floor leadership. He was named Most  Valuable Player three times (1987, 1989, 1990). He retired after being  diagnosed with HIV in 1991, though he returned to the Lakers for brief  stints as a player and as a coach.</p><p>Johnson, Michael (Duane) (b. Sept. 13, 1967, Dallas, Texas, U.S.)  U.S. sprinter. For much of the 1990s he was virtually unbeaten in the  200-m and 400-m races. He shared an Olympic gold medal in 1992 on  the world-record-setting 4 x 400-m relay team, and at the 1996 Olympics  he became the first man to win gold medals in both the 200 m and 400  m, setting a world record of 19.32 seconds in the 200 m. In 1999 he set  a new world record of 43.18 seconds in the 400 m. In the 2000 Olym�  pics he again won two gold medals.</p><p>Johnson, Philip C(ortelyou) (b. July 8, 1906, Cleveland, Ohio,  U.S.�d.

He gained fame with  his own Glass House (1949), which  struck a balance between the influ�  ence of Ludwig Mies van der Rohe  (later his collaborator on the Seagram  Building) and Classical allusion. His  style took a striking turn with the  AT&amp;T headquarters, New York  (1984), a controversial postmodern�  ist landmark.

As a colonel in the War of 1 812, he was wounded in the  Battle of the Thames, where he reputedly killed Tecumseh. He returned to  his congressional seat and later was elected to the Senate (1819-29). He  was a loyal supporter of Pres. Andrew Jackson, who chose him as Martin  Van Buren�s running mate in the 1836 election. None of the four vice-  presidential candidates won an electoral-vote majority, and the outcome  was decided by the Senate, the only such occurrence in U.S. history.  Johnson served one term in the office.</p><p>Johnson, Robert (b. c. 1911, Hazlehurst, Miss., U.S.�d. Aug. 16,  1938, near Greenwood, Miss.) U.S. blues guitarist, singer, and songwriter.  Born to a sharecropping family, he learned harmonica and guitar, prob�  ably influenced by personal contact with Delta bluesmen such as Eddie  �Son� House and Charley Patton. He traveled widely throughout the  South and as far north as Chicago and New York City, playing at house  parties, juke joints, and lumber camps. In 1936-37 he recorded songs by  House and others, as well as originals such as �Me and the Devil Blues,�  �Hellhound on My Trail,� and �Love in Vain.� He is said to have died, at  age 27, after drinking strychnine-laced whiskey (possibly the work of a  jealous husband) in a juke joint. His eerie falsetto and masterly slide gui�  tar influenced many later blues and rock musicians.</p><p>Johnson, Robert Wood (b. Feb. 15, 1845, Carbondale, Pa., U.S.�d.

In 1885 he founded medical sup�  ply company Johnson &amp; Johnson with his brothers, and he served as its  president until his death. An early proponent of the teachings of Joseph  Lister, Johnson worked to make his products as germ-free as possible, and  the firm�s high-quality and inexpensive medical supplies, including anti�  septic bandages and dressings, proved of great value to surgery.

Dec. 13, 1784, London) British man of  letters, one of the outstanding figures of 18th-century England. The son  of a poor bookseller, he briefly attended Oxford University. He moved to  London after the failure of a school he and his wife had started. He wrote  for periodicals and was hired to catalog the great library of the earl of  Oxford. In 1755, after eight years of labour, he produced his monumen�  tal Dictionary of the English Language (1755), the first great English dic�  tionary, which brought him fame. He continued to write for such  periodicals as The Gentleman�s Magazine and The Universal Chronicle ,  and he almost single-handedly wrote and edited the biweekly The Ram�  bler (1750-52). He also wrote plays, none of which succeeded on the  stage. In 1765 he produced a critical edition of William Shakespeare with a  famous preface that did much to establish Shakespeare as the centre of  the literary canon. His travel writings include A Journey to the Western  Islands of Scotland (1775). His Lives of the Most Eminent English Poets,  10 vol. (1779-81), was a significant critical work. A brilliant conversa�  tionalist, he helped found the Literary Club (c. 1763), which became  famous for its members of distinction, including David Garrick, Edmund  Burke, Oliver Goldsmith, and Joshua Reynolds. His aphorisms helped make  him one of the most frequently quoted of English writers. The biography  of Johnson written by his contemporary James Boswell is one of the most  admired biographies of all time.</p><p>Johnson, Virginia See William Masters and Virginia E(shelman)  Johnson</p><p>Johnson, Walter (Perry) (b.

A right-handed  thrower with a sidearm delivery who batted right as well, Johnson pitched  for the Washington Senators of the American League from 1907 through  1927. He holds the all-time record for most shutouts (110), ranks second  to Cy Young in wins (416), and established the record for his time for  most strikeouts (3,508; broken in 1983).

He purchased his first tract of land two years later, thus  beginning the acquisitions that eventually made him one of the largest  landholders and wealthiest settlers in British America. He fostered  friendly relations with the Indians; his ties with them were further  cemented when, following the death of his first wife, he married succes�  sively two Mohawk women. In 1746 he was appointed colonel of the Iro�  quois Confederacy. In the French and Indian War he defeated French forces  at Lake George, N.Y. (1755), and captured Fort Niagara (1759). He was  appointed superintendent of the Six Iroquois Nations (1756-74), helped  subdue the Indian uprising called Pontiac�s War (1763-64), and negoti�  ated the first Treaty of Fort Stanwix (1768).</p><p>Johnston, Joseph E(ggleston) (b.

At the start of the  American Civil War he resigned his commission to serve the Confederacy.  Appointed brigadier general, he won the first Confederate victory at the  Battle of Bull Run. He was promoted to general but remained at odds with  Confederate Pres. Jefferson Davis. He defended Richmond in the Penin�  sular Campaign and was badly wounded at the Battle of Fair Oaks (1862).  In 1863 he was sent to conduct the Vicksburg Campaign. His order to  evacuate the city was countermanded by Davis, but Johnston was blamed  for the city�s fall. As commander of the Army of the Tennessee, he avoided  defeat as the Union advanced toward Atlanta, Ga., but he was removed  from command for failing to defeat the invaders. Restored to duty in 1865,  he was forced to surrender to William T. Sherman.</p><p>Johnstown Flood Disastrous flood (1889) in the town of Johnstown,  Pa., U.S. Johnstown lies at the confluence of the Conemaugh River and  Stony Creek; at the time of the flood it was a leading U.S. steelmaking  centre.

Present in nearly all surface rocks, joints  extend in various directions, generally more vertical than horizontal.  Joints may have smooth, clean surfaces, or they may be scarred by slick-  ensides, or striations. Jointing does not extend very far into the Earth�s  crust, because at about 7.5 mi (12 km) even rigid rocks tend to flow plas�  tically in response to stress.</p><p>joint Structure connecting two or more bones.

Jolson�s family arrived in the U.S. in  1893 and settled in Washington, D.C., where Jolson made his first stage  appearance in 1899, performing in vaudeville before joining a minstrel  troupe (see minstrel show) in 1909. In New York City he was featured in  musicals such as La Belle Paree (1911), Honeymoon Express (1913), and  Big Boy (1925). In Sinbad (1918) he transformed the unsuccessful George  Gershwin song �Swanee� into his trademark number. In Bombo (1921) he  introduced �My Mammy,� �Toot, Toot, Tootsie,� and �California, Here I  Come.� In 1927 he starred in The Jazz Singer, the first feature film with  synchronized speech as well as music and sound effects.

(1805). He was appointed staff colonel in 1805 by Napoleon I, who had  read his book. He was created a baron after the Treaties of Tilsit (1807).  He rose to the post of chief of staff, but unjust treatment by his superiors  prompted him to resign (1813), and thereafter he fought for France�s  enemy, Russia. Of his numerous later works on military history and strat�  egy, the best known are Principles of Strategy (1818) and Summary of the  Art of War (1838). He was the first to fix divisions between strategy, tac�  tics, and logistics, and his systematic attempt to define the principles of  warfare made him a founder of modern military thought.</p><p>Jomon \'j6-,man\ culture (c. 7500-c. 250 bc) Mesolithic culture char�  acterized by pottery decorated with cord patterns (jomon).

They used chipped-stone and later polished-stone tools and  made clothing of bark. Though their pottery was technically primitive, it  demonstrated diverse forms and imaginative designs and decorations.  Many contemporary Ainu believe themselves to be descended from the  Jomon people.

(His narrative is part of a larger  book, The Twelve, in the Jewish canon, and he is first mentioned in the  book of Kings.) God orders Jonah to prophesy against the wickedness of  Nineveh, but Jonah refuses to believe that the people of this hated foreign  city deserve salvation, and he sails away on a ship in the opposite direc�  tion. When a great storm threatens to destroy the ship, he confesses his  fault and asks the crew to throw him overboard. A great fish swallows  him, but he prays for deliverance and the fish spews him out on dry  ground. He goes on to Nineveh and preaches God�s message; its sinful  people repent and are saved by God. Jonah is angered over the salvation  of the Ninevites and hopes that the city will be destroyed, for which God  rebukes him. The book, which opposes the narrow Jewish nationalism of  the time, was probably written in the 5th or 4th century bc.</p><p>Jonathan In the Hebrew scriptures, the eldest son of King Saul and  friend of David. A warrior in the Israelite army, he is first mentioned as  victor over the Philistines at Geba. After David joined Saul�s household,  he and Jonathan became close friends.

When the  two met for the last time, they planned that David would be the next king  of Israel and Jonathan his prime minister, but Saul and Jonathan were  killed in battle at Mount Gilboa.</p><p>Jones, Bill T. orig.

He wrote several masques for the court of James I and created the �anti�  masque� to precede the masque proper. His classic plays Volpone (1605-  06), The Alchemist (1610), and Bartholomew Fair (1614) use satire to  expose the follies and vices of his age, attacking greed, charlatanism, and  religious hypocrisy as well as mocking the fools who fall victim to them.  Regarded as the era�s leading dramatist after William Shakespeare, Jonson  influenced later playwrights, notably in the dramatic characterization of  Restoration comedies (see Restoration literature).

Jordan�s economy is based largely on manu�  facturing and services (including tourism); exports include phosphate, pot�  ash, pharmaceuticals, fruits and vegetables, and fertilizers. Jordan is a  constitutional monarchy with two legislative houses; the head of state and  government is the king, assisted by the prime minister. Jordan shares much  of its history with Israel, since both occupy parts of the area known his�  torically as Palestine. Much of present-day Jordan was once part of the king�  dom of Israel under David and Solomon (c. 1000 bc). It fell to the Seleucids  in 330 bc and to Muslim Arabs in the 7th century ad. The Crusaders  extended the kingdom of Jerusalem east of the Jordan River in 1099. The  region became part of the Ottoman Empire during the 16th century. In 1920  the area comprising Jordan (then known as Transjordan) was established  within the British mandate of Palestine. Britain recognized Transjordan�s  partial independence in 1923, although the British mandate did not end  until 1948. In 1950, after the end of hostilities with the new State of Israel,  Jordan annexed the West Bank and east Jerusalem, administering the terri�  tory until Israel gained control of it in the Six-Day War of 1967. In 1970-71  Jordan was wracked by fighting between the government and guerrillas of  the Palestine Liberation Organization (PLO), a struggle that ended with the  PLO being expelled from Jordan. In 1988 King Hussein renounced all Jor�  danian claims to the West Bank in favour of the PLO. In 1994 Jordan and  Israel signed a full peace agreement.</p><p>Jordan, Barbara C(harline) (b.

In Christianity it is known  as the place where John the Baptist baptized Jesus.</p><p>joruri See bunraku</p><p>Jose Bonifacio See Jose Bonifacio de Andrada e Silva</p><p>Joseph In the Old Testament, the son of the patriarch Jacob and his wife,  Rachel. He was favoured by his father, and his brothers became bitterly  jealous when he was given a resplendent �coat of many colors� (literally,</p><p>coat with flowing sleeves). They sold him into slavery in Egypt, telling  Jacob he had been killed by a wild beast. In Egypt Joseph gained favour  with the pharaoh and rose to high office, owing to his ability to interpret  dreams, and his acquisition of grain supplies enabled Egypt to withstand  a famine. When famine forced Jacob to send his sons to Egypt to buy  grain, the family was reconciled with Joseph and settled there. The story  of Joseph, told in Genesis 37-50, depicts the preservation of Israel and  begins the history of the Israelites in Egypt that is continued in Exodus.</p><p>Joseph II (b. March 13, 1741, Vienna�d. Feb. 20, 1790, Vienna) Holy  Roman emperor (1765-90). He suc�  ceeded his father, Francis I, and ini�  tially coruled with his mother, Maria  Theresa (1765-80). After his mother�s  death he tried to continue her work of  reform. Considered a practicioner of  �enlightened despotism,� he abol�  ished serfdom, established religious  equality before the law, granted free�  dom of the press, and emancipated  the Jews. He came into conflict with  the Roman Catholic church by  attempting to impose state controls  over it, and traditional countries such  as the Austrian Netherlands and Hun�  gary resisted his far-reaching  reforms. His foreign policies were  generally failures; he tried to  exchange the Austrian Netherlands  for Bavaria but was stopped by Prus�  sia. An alliance with Catherine II of  Russia engaged Austrian troops in a  war with Turkey, but Joseph had to  return home to head off revolutionary unrest in Hungary and the Austrian  Netherlands.</p><p>Joseph, Chief (b. c. 1840, Wallowa Valley, Ore.Terr.�d. Sept. 21,  1904, Colville Reservation, Wash., U.S.) Nez Perce chief. In 1877 the U.S.  attempted to force the Nez Perce to move to a reservation in Idaho. Chief  Joseph at first agreed but later decided instead to lead his followers on a  trek to Canada. During the three-month, 1,000-mile journey, he outma-  neuvered and outfought federal troops, and his humane conduct won the  admiration of many whites. His group was finally surrounded near the  Canadian border and subsequently removed to Indian Territory (Okla�  homa). In 1885 they were relocated to a reservation in Washington.</p><p>Joseph, Father orig. Francois-Joseph le Clerc du Tremblay</p><p>(b. Nov. 4, 1577, Paris, France�d. Dec. 18, 1638, Rueil) French mystic  and religious reformer. He joined the Capuchins in 1599. His fervent  ambition to convert European Protestants to Roman Catholicism coin�  cided with cardinal de Richelieu�s plans for French domination of Europe,  and he became Richelieu�s secretary in 1611. He became known as the  �Gray Eminence� (for his gray Capuchin cloak), and his close collabo�  ration with Richelieu (the �Red Eminence�) gave him powers akin to  those of a foreign minister, especially during Richelieu�s campaign to  finance France�s participation in the Thirty Years' War, which Joseph�s  policies did much to bring about.</p><p>Joseph, Saint (fl. 1st century ad, Nazareth, Galilee region of Pales�  tine; principle feast day March 19; Feast of St. Joseph the Worker May  1) In the New Testament, the husband of Mary and the earthly father of  Jesus. Descended from the house of David, he was a carpenter in Naza�  reth. Betrothed to Mary when he found her already pregnant, an angel  appeared to him in a vision and told him the expected child was the son  of God. He and Mary journeyed to Bethlehem to be counted in the Roman  census, and while they were there the child was born.

A leader of Paris  society, she married Napoleon in a  civil ceremony in 1796. She was an  indifferent and extravagant wife, but  during the Consulate she used her  social position to advance her hus�  band�s political fortunes. After he  became emperor (1804), she per�  suaded him to marry her again, with  religious rites. She proved unable to  give him a son, and in 1810 he  arranged for their marriage to be nul�  lified so that he could make a politi�  cally convenient marriage with  Marie-Louise.</p><p>Josephson, Brian D(avid) (b. Jan. 4, 1940, Cardiff, Wales) British  physicist. He received a Ph.D. from the University of Cambridge and  began building on earlier work done by Leo Esaki of IBM and Ivar Giae-  ver (b. 1929) of General Electric. For his discovery of what is now called  the Josephson effect in superconductivity, he shared a Nobel Prize with  Esaki and Giaever in 1973. He was elected a fellow of the Royal Society  in 1970 and was named a professor at Cambridge in 1974.</p><p>Josephson effect Flow of electric current between two pieces of  superconducting material (see superconductivity) separated by a thin layer  of insulating material. This flow was predicted by the British physicist  Brian Josephson in 1962, based on the BCS theory (see John Bardeen).  According to Josephson, pairs of electrons can move from one supercon�  ductor to the other across the insulating layer (tunneling). The locus of  this action is called a Josephson junction. The Josephson current flows  only if no battery is connected across the two conductors. A major appli�  cation of this discovery is in superfast switching devices used in comput�  ers, which can be 100 times faster than ordinary semiconducting circuits.</p><p>Josephus Vjo-'se-fssV Flavius orig. Joseph Ben Matthias (b. ad</p><p>37/38, Jerusalem�d. c. 100, Rome) Jewish priest, scholar, and historian.  Born of a priestly family, Josephus joined the Pharisees. While on a dip�  lomatic mission he was impressed by the culture and sophistication of  Rome, and in the Jewish revolt of ad 66-70 he eventually attached him�  self to the Roman cause. Favoured in the courts of emperors Vespasian,  Titus, and Domitian, he wrote valuable historical works. His History of the  Jewish War (79) is the principal source on the revolt and includes much  on Roman tactics and strategy. The Antiquities of the Jews (93), his great�  est work, traces Judaism from creation up to the revolt. Against Apion  defends Judaism against Hellenism.</p><p>Joshua Leader of the Israelite tribes after the death of Moses. Accord�  ing to the biblical book of Joshua, Joshua led the people of Israel west�  ward across the Jordan River to invade Canaan. Under his leadership the  Israelites conquered the Canaanites and gained control of the Promised  Land. The book begins by recounting the battles, including the famous  demolition of the walls of Jericho. Joshua then divides Canaan among the  12 tribes of Israel, makes his farewell speech, and dies. The book was  compiled much later than the events described, perhaps during the Baby�  lonian Exile in the 6th century bc.</p><p>Joshua Tree National Park National park, southeastern California,  U.S. Situated on the border between the Mojave and Colorado deserts, it  has an area of 1,241 sq mi (3,214 sq km). It was designated a national  monument in 1936 and a national park in 1994. It is noted for its variety  of desert plant life, including the Joshua tree, creosote bush, and Mojave  yucca. Its fauna include coyotes, bobcats, and tarantulas.</p><p>Josiah \jo-'sI-3\ (b. c. 640 bc �d. 609 bc) King of Judah and religious  reformer. He became king at age 8 after the assassination of his father,  Amon. As the Assyrian empire crumbled, Judah gained a measure of  independence, and in 621 bc Josiah began a program of national renewal.  He drove out foreign cults, abolished local sanctuaries, and centred the  worship of Yahweh in the Temple of Jerusalem. As his reforms were under  way, parts of the book of Deuteronomy were discovered in the Temple,</p><p>giving added impetus to his efforts to revive observance of Mosaic law.  Josiah hoped to reunify Judah and Israel, but he was killed in a battle  against the Egyptians.</p><p>Jospin, Lionel (b.

He joined  the foreign service and later taught economics at the University Institute  of Technology of Paris-Sceaux. He was elected to the National Assem�  bly in 1977 and later was appointed head of the party by Pres. Francois  Mitterrand. He served as minister of education and narrowly lost the presi�  dential election in 1995 to Jacques Chirac. After the Socialists and their  allies won a majority in the National Assembly in 1997, he was appointed  prime minister by Chirac. He resigned in 2002 after an unsuccessful presi�  dential bid.</p><p>Josquin des Prez \zh6s-'ka n -de-'pra\ (b. c. 1445, Conde-sur-l�Escaut?,  Burgundian Hainaut�d. Aug. 27,</p><p>1521, Conde-sur-l�Escaut) Northern  French composer. Perhaps a student  of Johannes Ockeghem, he spent his  life working as a singer, moving  from post to post in Italy, including  the Milan Cathedral (1459-72) and  the Papal Chapel (1486-94), before  returning to Conde in 1504, where he  would spend the rest of his life. Jos�  quin was able to balance complexity  of imitative counterpoint with an  inexhaustible melodic gift. He left  over 60 motets (including Absalon,  fill mi), some 18 complete masses  (including Missa Pange lingua), and  many superb secular songs in the  chordal �Italian� style (including �El  grillo�). The first music printer, Ottaviano Petrucci, devoted an entire vol�  ume to Josquin�s works, an honour accorded to no other composer. His  posthumous reputation, as attested by Martin Luther and others, was the  greatest of any composer up to his time, and his works were closely imi�  tated throughout the 16th century.</p><p>Jotunheim \'yo-t 3 n-,ham\ Mountains Mountain range, south-central  Norway.

The mountains are mentioned in early  Norse sagas, but they were not fully explored until the early 19th century.</p><p>Joule VjiilV James (Prescott) (b. Dec. 24, 1818, Salford, Lancash�  ire, Eng.�d. Oct. 11, 1889, Sale, Cheshire) English physicist. After study�  ing under John Dalton, in 1840 he described �Joule�s law,� which stated  that the heat produced in a wire by an electric current is proportional to  the product of the resistance of the wire and the square of the current. In  1843 he published his value for the amount of work required to produce  a unit of heat, called the mechanical equivalent of heat, and established  that heat is a form of energy. He established that the various forms of  energy are basically the same and can be changed from one into another,  a discovery that formed the basis of the law of conservation of energy,  the first law of thermodynamics. In his honour, the value of the mechani�  cal equivalent of heat is usually represented by the letter J, and a stan�  dard unit of work is called the joule.</p><p>journalism Collection, preparation, and distribution of news and  related commentary and feature materials through media such as pam�  phlets, newsletters, newspapers, magazines, radio, film, television, and  books. The term was originally applied to the reportage of current events  in printed form, specifically newspapers, but in the late 20th century it  came to include electronic media as well. It is sometimes used to refer to  writing characterized by a direct presentation of facts or description of  events without an attempt at interpretation. Colleges and universities con�  fer degrees in journalism and sponsor research in related fields such as  media studies and journalism ethics.</p><p>jousting Medieval Western European mock battle between two horse�  men who charged at each other with leveled lances in an attempt to unseat  the other.

Feb. 2, 1882, Dublin,  Ire.�d. Jan. 13, 1941, Zurich,</p><p>Switz.) Irish novelist. Educated at a  Jesuit school (though he soon  rejected Catholicism) and at Univer�  sity College, Dublin, he decided  early to become a writer. In 1902 he  moved to Paris, which would  become his principal home after  years spent in Trieste and Zurich. His  life was difficult, marked by financial  troubles, chronic eye diseases that  occasionally left him totally blind,  censorship problems, and his daugh�  ter Lucia�s mental illness. The  remarkable story collection The  Dubliners (1914) and the autobio�  graphical novel Portrait of the Artist  as a Young Man (1916), his early  prose volumes, were powerful  examples of his gift for storytelling  and his great intelligence. With  financial help from friends and sup�  porters, including Ezra Pound, Sylvia  Beach (1887-1962), and Harriet Shaw Weaver (1876-1961), he spent  seven years writing Ulysses (1922), the controversial masterpiece (ini�  tially banned in the U.S. and Britain) now widely regarded by many as  the greatest English-language novel of the 20th century. It embodies a  highly experimental use of language and exploration of such new liter�  ary methods as interior monologue and stream-of-consciousness narrative.  He spent 17 years on his final work, the extraordinary Finnegans Wake  (1939), famous for its complex and demanding linguistic virtuosity.</p><p>Joyner, Florence Griffith See Florence Griffith Joyner</p><p>Joyner-Kersee, Jackie orig.

After Francisco  Franco abolished the republic and declared Spain a representative mon�  archy, he prepared Juan Carlos for his future role, paying particular atten�  tion to his military education. In 1969 Juan Carlos was designated prince;  he acceded to the Spanish throne two days after Franco�s death. Although  he had sworn loyalty to Franco�s National Movement, he proved to be</p><p>relatively liberal and helped restore parliamentary democracy. In 1981 he  deflated a potential military coup and preserved the democracy. He  became the first Spanish king to visit the Americas and was the first  crowned monarch to make an official visit to China.

After  Charles�s death, Philip gave him the name Don Juan de Austria (1559).  He served as a Spanish military commander, and in 1571 he was appointed  head of naval forces of the Holy League against the Ottoman Turks,  achieving victory in the Battle of Lepanto. In 1576 he was appointed  governor-general of the Netherlands, then in open revolt against Spanish  authority.

He led La Reforma, a liberal  political and social revolution in  Mexico, and, when liberal forces  gained control of the national gov�  ernment in 1855, he was able to  implement his ideas. In 1857 he was  elected head of the Supreme Court,  which, under a new constitution,  placed him first in the order of presi�  dential succession. In 1858 a coup by  conservative forces sent Mexico�s  president into exile, but Juarez suc�  ceeded him and headed a liberal gov�  ernment that opposed the regime installed by the conservatives. After  three years of civil war, the liberals prevailed. Juarez was elected presi�  dent in 1861 and twice reelected. Early in his first term, the French under  Napoleon III invaded and occupied Mexico, putting Maximilian of Austria  in power in 1864.

It covered much of Inner Asia and all of northern China. Like the Liao,  an earlier Inner Asian dynasty, the Juchen maintained a Chinese-style  bureaucracy to rule over the southern part of their conquests and a tribal  state to rule in Inner Asia. Very conscious of preserving their ethnic iden�  tity, they maintained their language, developed their own script, and  banned Chinese clothes and customs from their army.</p><p>Judaea or Judea \ju-'de-3\ Southern division of ancient Palestine suc�  cessively under Persian, Greek, and Roman rule. It was bounded on the  north by Samaria and on the west by the Mediterranan Sea. It succeeded  the Hebrew kingdom of Judah, which was destroyed by the Babylonians.  The revived kingdom of Judaea was established by the Maccabees, who  resisted the suppression of Judaism under foreign rule. Family disputes  led to Roman intervention in 63 bc. Under Roman control, Herod (the  Great) was made king of Judaea in 37 bc. After Herod�s death the coun�  try was ruled alternately by his descendants (see Herod Antipas; Herod  Agrippa I) and by Roman procurators. As a result of the Jewish revolt in  ad 66, the city of Jerusalem was destroyed (ad 70). The name Judaea is  used by Israelis to describe approximately the same area in the modem  West Bank territory.</p><p>Judah One of the 12 tribes of Israel, descended from Judah, the fourth son  of Jacob. The tribe of Judah entered Canaan with the other Israelites after  the escape from Egypt and settled in the region south of Jerusalem. It even�  tually became the most powerful tribe, producing the kings David and  Solomon, and it was prophesied that the Messiah would come from among  its members. After the 10 northern tribes were dispersed by the Assyrian  conquest of 721 bc, the tribes of Judah and Benjamin were left as the sole  inheritors of the Mosaic covenant. Judah flourished until 586 bc, when it  was overrun by the Babylonians and many of its people were carried into  exile. Cyrus II allowed them to return in 538 bc, and the Temple of Jerusalem  was rebuilt. The history of Judah from that time forward is the history of the  Jews and Judaism. The kingdom of Judah was succeeded by Judaea.</p><p>Judah ben Samuel (d. 1217) Jewish mystic and scholar. He was a  member of the Kalonymos family, which provided medieval Germany with  many Jewish mystics and spiritual leaders. Around 1195 he settled in  Regensburg, where he founded a yeshiva and gathered disciples such as  Eleazar ben Judah of Worms. He was the founder of 12th-century German  Hasidism, an ultrapious movement not directly related to 18th-century  Hasidism. Book of the Pious , a compilation of the writings of Judah, his  father, and Eleazar of Worms, offers a detailed manual of conduct for obser�  vant Jews; it is one of the most important documents of medieval Judaism.</p><p>Judah ha-Nasi Vjii-ds-.ha-na-'seX (b. ad 135�d. c. 220) Palestinian  Jewish scholar. A descendant of the great sage Hillel, he was patriarch of  the Jewish community in Palestine and head of its Sanhedrin, and he  became an important figure in early rabbinic Judaism. He spent over 50  years studying the oral law and is said to have compiled it into six sec�  tions divided by subject matter, thus creating the Mishna. His exact role  in the Mishna�s redaction is not known; other scholars such as Meir and  Akiba ben Joseph were probably also involved.</p><p>Judaism Vjti-ds-.i-zsm, 'jii-de-.i-zomX Religious beliefs and practices of  the Jews. One of the three great monotheistic world religions, Judaism  began as the faith of the ancient Hebrews, and its sacred text is the Hebrew  Bible, particularly the Torah. Fundamental to Judaism is the belief that the  people of Israel are God�s chosen people, who must serve as a light for  other nations. God made a covenant first with Abraham and then renewed  it with Isaac, Jacob, and Moses. The worship of Yahweh (God) was cen�  tred in Jerusalem from the time of David. The destruction of the First  Temple of Jerusalem by the Babylonians (586 bce) and the subsequent exile  of the Jews led to hopes for national restoration under the leadership of  a Messiah. The Jews were later allowed to return by the Persians, but an  unsuccessful rebellion against Roman rule led to the destruction of the</p><p>Second Temple in 70 ce and the Jews� dispersal throughout the world in  the Jewish Diaspora. Rabbinic Judaism emerged to replace the beliefs and  practices associated with the Temple at Jerusalem, as the Jews carried on  their culture and religion through a tradition of scholarship and strict  observance. The great body of oral law and commentaries were commit�  ted to writing in the Talmud and Mishna. The religion was maintained  despite severe persecutions by many nations.</p><p>Two branches of Judaism emerged in the Middle Ages: the Sephardic,  centred in Spain and culturally linked with the Babylonian Jews; and the  Ashkenazic, centred in France and Germany and linked with the Jewish  culture of Palestine and Rome. Elements of mysticism also appeared, nota�  bly the esoteric writings of the Kabbala and, in the 18th century, the move�  ment known as Hasidism. The 18th century was also the time of the Jewish  Enlightenment (Haskala). Conservative and Reform Judaism emerged in  19th-century Germany as an effort to modify the strictness of Orthodox  Judaism. By the end of the 19th century Zionism had appeared as an out�  growth of reform. European Judaism suffered terribly during the Holo�  caust, when millions were put to death by the Nazis, and the rising flow  of Jewish emigrants to Palestine led to the declaration of the State of Israel  in 1948. In the early 21st century there were nearly 15 million Jews  worldwide.</p><p>Jewish Festivals</p><p>Tishri (Sept.-Oct.)</p><p>1-2</p><p>Rosh Hashanah (New Year)</p><p>3</p><p>Fast of Gedaliah</p><p>10</p><p>Yom Kippur (Day of Atonement)</p><p>15-21</p><p>Sukkot (Tabernacles)</p><p>22</p><p>Shemini Atzereth (Eighth Day of Solemn  Assembly)</p><p>23</p><p>Simhath Torah (Rejoicing of the Law)</p><p>Kislev (Nov.-Dee.)</p><p>25</p><p>Hanukkah (Festival of Lights) begins</p><p>Tebet (Dec-Jan.)</p><p>2 or 3</p><p>Hanukkah ends</p><p>10</p><p>Fast</p><p>Shebat (Jan.-Feb.)</p><p>15</p><p>New Year for Trees</p><p>Adar (Feb.-Mar.)</p><p>13</p><p>Fast of Esther</p><p>14-15</p><p>Purim (Feast of Lots)</p><p>Second Adar (Adar Sheni) or Veadar (intercalated month); Adar holidays fall in</p><p>Veadar during leap years.</p><p>Nisan (Mar.-Apr.)</p><p>15-22</p><p>Pesach (Passover)</p><p>lyar (Apr.-May)</p><p>5</p><p>Israel Independence Day</p><p>18</p><p>Lag b'Omer (33rd Day of the Omer Counting)</p><p>Sivan (May-June)</p><p>6-7</p><p>Shabuoth (Feast of Weeks, or Pentecost)</p><p>Tammuz (June-July)</p><p>17</p><p>Fast</p><p>Ab (July-Aug.)</p><p>9</p><p>Fast</p><p>Judas Iscariot (d. c. ad 30) Disciple who betrayed Jesus. He was one  of the original 12 disciples. Judas made a deal with the Jewish authori�  ties to betray Jesus into their custody; in return for 30 pieces of silver, he  brought the armed guard to the Garden of Gethsemane and identified Jesus  with a kiss. He later regretted his deed and committed suicide; according  to Matthew 27, he returned the money to the priests before hanging him�  self. His surname may mean �man of Kerioth,� or it may link him to the  Sicarii, a band of radical Jewish terrorists.</p><p>Judas Maccabaeus V.ma-ko-'be-osV (d. 161/160 bc) Leader of a Jew�  ish rebellion against the Syrians. The son of an aged priest who took to  the mountains in rebellion when Antiochus IV Ephiphanes tried to impose  the Greek religion on the Jews, Judas became leader of the rebels on his  father�s death and won a series of victories over the Syrians in 166-164  bc. In 166 he purified the Temple of Jerusalem, an event celebrated at  Hanukkah. On Antiochus�s death in 164, the Seleucids offered the Jews  freedom of worship, but Judas continued the war, hoping to gain politi�  cal freedom. He was killed soon thereafter, but his brothers carried on the  struggle. The history of the dynasty is told in the two books of Macca�  bees in the Apocrypha.</p><p>Judd, Donald (b. June 3, 1928, Excelsior Springs, Mo., U.S.�d. Feb.  12, 1994, New York, N.Y.) U.S. sculptor. He studied at Columbia Uni�  versity and the Art Students League. He had his first one-man exhibition  in 1957. In 1959 he began writing reviews for Art News and Arts Maga�  zine. In 1960-62 he made the transition from painting to sculpture and  became a leading exponent of Minimalism. Much of his work consists of  simple cubes or other geometric units that stand on the floor or are can�  tilevered from the wall, often in stacks or horizontal progressions. His</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Judea &#x25BA; Julian I 1003</p><p>materials included painted steel, Plexiglas, iron, wood, and concrete.

In jury cases, the judge pre�  sides over the selection of the panel and instructs it concerning pertinent  law. The judge may also rule on motions made before or during a trial.  In the U.S., judges are elected or appointed. Most federal judges are  appointed for life by the president with the advice and consent of the Sen�  ate. The highest-ranking judge in the U.S. legal system is the chief justice  of the Supreme Court. See also judgment, judiciary, magistrate's court, Mis�  souri Plan.</p><p>judgment In law, a formal decision or determination on a matter or  case by a court. Judgments are classified as in personam , in rem, and quasi  in rem. A judgment in personam determines the rights and liabilities of a  particular person. A judgment in rem affects the status of a particular thing  (e.g., an item of property). The designation quasi in rem describes a judg�  ment in which a person�s property is subject to court control to satisfy a  claim against the person. The court has at its disposal the power to pun�  ish for contempt any party that does not adhere to its orders. See also appeal;  DECLARATORY JUDGMENT; DEMURRER.</p><p>Judgment, Day of In Christianity, the final judgment of God on all  people at the end of history. It will occur at the second coming of Christ,  when the dead are resurrected. It is especially important in millennialist  denominations (see millennialism). In Islam, the Day of Judgment is  described in the Quran and the Hadith. Religions that include reincarna�  tion (e.g., Hinduism) lack a Day of Judgment; the determination of how an  individual is to be reborn being a particular judgment on the merit of the  life just lived (see karma).</p><p>judgment tale See dilemma tale</p><p>judicial review Examination by a country�s courts of the actions of  the legislative, executive, and administrative branches of government to  ensure that those actions conform to the provisions of the constitution.  Actions that do not conform are unconstitutional and therefore null and  void. The practice is usually considered to have begun with the ruling by  the Supreme Court of the United States in Marbury v. Madison (1803). Sev�  eral constitutions drafted in Europe and Asia after World War II incorpo�  rated judicial review. Especially subject to scrutiny in the U.S. have been  actions bearing on civil rights (or civil liberty), due process of law, equal  protection under the law, freedom of religion, freedom of speech, and rights  of privacy. See also checks and balances.</p><p>judiciary Branch of government in which judicial power is vested. The  principal work of any judiciary is the adjudication of disputes or contro�  versies. Regulations govern what parties are allowed before a judicial  assembly, or court, what evidence will be admitted, what trial procedure  will be followed, and what types of judgments may be rendered. Typically  present in court are the presiding judge, the parties to the matter (sometimes  called litigants), the lawyers representing the parties, and other individuals  including witnesses, clerks, bailiffs, and jurors when the proceeding  involves a jury. Though the courts� stated function is to administer justice  according to rules enacted by the legislative branch, courts also unavoid�  ably make law. In deciding, for example, how legislative provisions are to  be applied to specific cases, the courts in effect make law by laying down  rules for future cases; this is known as the doctrine of precedent. In some  jurisdictions, courts have the power of judicial review, enabling them to  declare unconstitutional legislation or acts of the executive.</p><p>Judith Legendary Jewish heroine, the central character in the Book of  Judith in the Apocrypha. (The book is excluded from the Hebrew Bible.)  A beautiful Jewish widow whose city is besieged by the Assyrians under  their general, Holofemes, Judith leaves the city in pretended flight and  foretells victory to Holofernes. Invited into his tent, she cuts off his head  as he lies in a drunken sleep, and the Jews defeat the leaderless Assyri�  ans. Probably fictional, the story may have been written in the 2nd cen�  tury bc, after the end of the Maccabean revolt.</p><p>judo Martial art that emphasizes the use of quick movement and lever�  age to throw an opponent. Its techniques are generally intended to turn  an opponent�s force to one�s own advantage rather than to oppose it  directly. The opponent must be thrown cleanly, pinned, or mastered</p><p>through the application of pressure to arm joints or the neck. Judo is now  practiced primarily as sport. It became an Olympic sport in 1964; wom�  en�s judo was added in 1992. The sport evolved out of jujitsu in late-19th-  century Japan.</p><p>juge d'instruction \'zhmzh-da n -strLek-syo n \ French "judge of in�  quiry" In France, a magistrate responsible for conducting the investi�  gative hearing that precedes a criminal trial. In this hearing the major  evidence is presented, witnesses are heard, and depositions are taken. If  at the end of the hearing the magistrate is not convinced that the evidence  of guilt is sufficient to warrant a trial, no trial occurs. This process differs  from the grand jury hearing in the Anglo-American system.</p><p>Jugendstil Vyti-gont-.shtelX Artistic style that arose near the end of the  19th century in Germany and Austria. Its name was derived from the  Munich magazine Die Jugend (�Youth�), founded in 1896, which featured  Art Nouveau designs. Its early phase, primarily floral in character, was  rooted in English Art Nouveau and Japanese prints; a more abstract phase  emerged after 1900. Primarily a style in architecture and the decorative  arts, it also included the great Austrian painter Gustav Klimt.</p><p>juggler Entertainer who keeps several plates, knives, balls, or other  objects in the air at once by tossing and catching them. The art of jug�  gling has been practiced since antiquity. Through the 18th century jug�  glers performed at fairs and marketplaces, and in the 19th century they  found larger audiences in ciRCUSes and music halls. In these training grounds  the art advanced in technical perfection, producing outstanding perform�  ers such as Enrico Rastelli, who could juggle 10 balls. Modern jugglers  introduced variations such as performing while blindfolded on horseback,  on a high wire, or on a unicycle.</p><p>Jugurtha \ju-'g9r-th3\ (b. c. 160 bc �d. 104, Rome) Ruler of the North  African kingdom of Numidia under the Romans (118-105 bc). After the  death of his uncle Micipsa, then ruler of Numidia, Jugurtha shared rule  with his two cousins. He had one killed and captured the capital city of  the other. Rome intervened with troops, which Jugurtha successfully out�  witted until he was captured in 105 bc.

Juilliard (1840-  1919). It is now the professional educational arm of the Lincoln Center for  the Performing Arts. It offers bachelor�s degrees in music, dance, and  drama and postgraduate degrees in music. The Juilliard String Quartet  (founded 1946) was important to the development of chamber music in  the U.S.</p><p>jujitsu \ju-'jit-sii\ Martial art that employs holds, throws, and paralyz�  ing blows to subdue or disable an opponent. It evolved among the samu�  rai warrior class in Japan from about the 17th century. A ruthless form of  fighting, its techniques included the use of hard or tough parts of the body  (e.g., knuckles, fists, elbows, and knees) against an enemy�s vulnerable  points. Jujitsu declined in the mid-19th century, but many of its concepts  and methods were incorporated into judo, karate, and aikido.</p><p>Julia (b. 39 bc �d. ad 14, Rhegium) Only child of Augustus. She wed  Marcellus, who died in 23 bc, then Agrippa (21), Augustus�s chief lieuten�  ant. Their two eldest sons were adopted by Augustus (17) and became his  heirs. When Agrippa died (12 bc), Augustus�s second wife persuaded him  to favour her sons (his stepsons), Tiberius and Drusus, as heirs. Augustus  forced Tiberius to divorce his wife and marry Julia (11 bc). The unhappy  Julia became promiscuous, and Tiberius went into self-imposed exile.  When Augustus discovered Julia�s behaviour, he banished her to an island  off Campania (2 bc), then to Rhegium. On becoming emperor, Tiberius  withheld her allowance, and she starved to death.</p><p>Julian or Julian the Apostate Latin Julianus Apostata orig.  Flavius Claudius Julianus (b. ad 331/332, Constantinople�d. June  26/27, 363, Ctesiphon, Mesopotamia) Roman emperor (361-363), noted  scholar and military leader. The nephew of Constantine I, he was raised a  Christian but converted to mystical paganism. As caesar (subemperor) in  the west, he restored the Rhine frontier and was proclaimed Augustus  (senior emperor) by his armies. Though Constantius II initially objected  to Julian as his successor, he accepted him on his deathbed (361). As  emperor Julian proclaimed freedom of worship for pagans and Christians  in 361; he nevertheless promoted paganism over Christianity, against</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1004 I Julian &#x25BA; June beetle</p><p>which he committed acts of violence  and persecution.

By the mid-1840s he was a  Whig member of the Indiana state  legislature and a frequent author of  antislavery newspaper articles.</p><p>Elected to the U.S. House of Repre�  sentatives as a member of the Free  Soil Party in 1848, he was that par�  ty�s vice-presidential candidate in  1852. In 1856 he helped form the Republican Party. Again serving in the  House (1861-71), he played an important role in making emancipation a  Northern war aim in the American Civil War. In 1867 he helped prepare  articles of impeachment against Pres. Andrew Johnson. He later wrote  books and articles on reform causes, including women�s suffrage.</p><p>Julian Alps Range of the eastern Alps.

Prince Bernhard, remained with Queen Wilhelmina� s govern�  ment, which had relocated to London. Returning to The Netherlands in  1945, Juliana acted as regent during her mother�s illness and became  queen when Wilhelmina abdicated. In 1980 she abdicated in favour of her  daughter Beatrix.</p><p>Julio-Claudian dynasty (ad 14-68) Successors of Augustus, the first  Roman emperor: Tiberius, Caligula, Claudius, and Nero. It was a loosely  defined set of kin relations rather than a direct bloodline. Tiberius�s rule  was competent, with notable accomplishments, but it ended in cruel tyr�  anny. The insane Caligula was wild and capricious. Under Claudius,  Rome experienced marked development. Under Nero the empire pros�  pered, but he was given to excesses, and his reign ended amid rebellion  and civil war.</p><p>Julius II orig. Giuliano della Rovere (b. Dec. 5, 1443, Albisola,  republic of Genoa�d. Feb. 21, 1513, Rome) Pope (1503-13). The  nephew of Sixtus IV, he fled Rome in 1494 to escape assassination by  Alexander VI. Elected pope in 1503, Julius set out to restore the Papal  States, subjugating Perugia and Bologna (1508) and defeating Venice  (1509) with the aid of the League of Cambrai. His first effort to expel the  French from northern Italy failed, but a popular revolt drove them out in  1512, and Parma and Piacenza were added to the Papal States. The great�  est art patron of all the popes, Julius was a close friend of Michelangelo,  from whom he commissioned the sculpture of Moses and the paintings  in the Sistine Chapel. He also commissioned Raphael�s Vatican frescoes.</p><p>Julius Caesar See Julius Caesar</p><p>July Days (1917) Period in the Russian Revolution of 1917 during which  Petrograd workers and soldiers staged armed demonstrations against the  provisional government that resulted in a temporary decline of Bolshevik  influence and in the formation of a new provisional government headed  by Aleksandr Kerensky. To undermine Bolshevik popularity, the govern�  ment produced evidence that Vladimir Ilich Lenin had ties with the German  government. The public reacted against the Bolsheviks, Lenin fled to Fin�</p><p>land, and Leon Trotsky and other leaders were jailed.

According to plan, Col. Claus von Stauffenberg (1907-  44) left a bomb in a briefcase in a conference room at the field headquar�  ters at Rastenburg, East Prussia, where Hitler was meeting with top  military aides. But the briefcase was pushed behind a table support, and  Hitler survived the blast with minor injuries. Meanwhile, the other con�  spirators in Berlin failed to act. The chief conspirators, including Stauffen�  berg, Gen. Ludwig Beck, Gen. Erwin Rommel, and other top officers, were  promptly shot or forced to commit suicide. In subsequent days, Hitler�s  police rounded up about 200 conspirators, who were shot, hanged, or  viciously strangled.</p><p>July Revolution (1830) Insurrection that brought Louis-Philippe to the  throne of France. It was precipitated on July 26 by Charles X�s publica�  tion of restrictive ordinances contrary to the spirit of the Charter of 1814.  Demonstrations were followed by three days of fighting (July 27-29),  Charles�s abdication, and the proclamation of Louis-Philippe as king. The  bourgeoisie secured a political and social ascendancy that was to charac�  terize the subsequent July Monarchy.</p><p>jump rope or skip rope Children�s game in which players hold a  rope (jump rope) at each end and twirl it in a circle, while one or more  players jump over it each time it reaches its lowest point. Dating from the  19th century, it is traditionally a girl�s sidewalk or playground game that  usually involves the chanting of a counting rhyme (e.g., �One, two, touch  my shoe�). There are many types of jumps, including single, double, and  backward; in �double Dutch,� two ropes are twirled simultaneously in  opposite directions. Single-rope jumping, or rope skipping, is popular  with boxers to develop the lungs and legs and improve coordination and  footwork.</p><p>JunaycJ Xju-'nldV Shaykh (b. 1430, Iranian Azerbaijan?�d. March 4,  1460, near the Kura River) Fourth head of the Safavid order of Sufi mys�  tics. He became head of the order on his father�s death in 1447 and set  out to turn a society known for piety and learning into a political force.  The arming of his followers led to a conflict with Jahan Shah (died 1467),  ruler of Iranian Azerbaijan, and resulted in the expulsion of Junayd and  his followers from Ardabll, the traditional centre of the Safavid order, in  1448. He continued his military adventurism in the lands of present-day  Syria and Turkey and was finally killed in battle against a force of Chris�  tian Circassians. His policies were carried on by his son, Haydar, and  eventually culminated in the found�  ing of the Safavid dynasty under  Junayd�s grandson, Isma'Tl I, assuring  the dominance of ShT'ite Islam in Iran.</p><p>junco Any of several species of  finchlike birds (genus Junco , family  Fringillidae), about 6 in.

The new  government instituted numerous radical reforms, but the new assembly,  composed mainly of moderate and conservative candidates, was deter�  mined to cut costs and end risky experiments such as public works pro�  grams to provide for the unemployed. Thousands of Parisian workers�  suddenly cut off from the state payroll�were joined by radical  sympathizers and took to the streets in spontaneous protest. The assem�  bly gave Gen. Louis- Eugene Cavaignac authority to suppress the uprising,  and he brought up artillery against the protesters� barricades.

Mining was important until the  Alaska-Juneau gold mine closed in 1944. Juneau was made the state capital  in 1959. Fishing, forestry, and government activities are important, as is  tourism. In 1970 Juneau merged with Douglas, on an island across the  channel, to form the largest U.S. city in area (3,108 sq mi [8,050 sq km]).</p><p>Jung VyuqV Carl (Gustav) (b. July 26, 1875, Kesswil, Switz.�d.  June 6, 1961, Kusnacht) Swiss psychiatrist. As a youth he read widely in  philosophy and theology. After taking his medical degree (1902), he  worked in Zurich with Eugen Bleuler on studies of mental illness. From  this research emerged Jung�s notion of the complex, or cluster of emo�  tionally charged (and largely unconscious) associations. Between 1907  and 1912 he was Sigmund Freud�s close collaborator and most likely suc�  cessor, but he broke with Freud over the latter�s insistence on the sexual  basis of neuroses. In the succeeding years Jung founded the field of ana�  lytic psychology, a response to Freud�s psychoanalysis. Jung advanced the  concepts of the introvert and extravert personality, archetypes, and the  collective unconscious (the pool of human experience passed from gen�  eration to generation). He went on to formulate new psychotherapeutic  techniques designed to reacquaint the person with his unique �myth� or  place in the collective unconscious, as expressed in dream and imagina�  tion. Sometimes dismissed as disguised religion and criticized for its lack  of verifiability, Jung�s perspective nonetheless remains influential in reli�  gion and literature as well as psychiatry. His important works include The  Psychology of the Unconscious (1912; revised as Symbols of Transfor�  mation), Psychological Types (1921), Psychology and Religion (1938),  and Memories, Dreams, Reflections (1962).</p><p>jungle fowl Any of four species of Asian birds (genus Gallus) that dif�  fer from other species in the pheasant family in having, in the male, a  fleshy comb, lobed wattles hanging below the bill, and a high-arched tail.

The cock has shining  silky plumage, red on the head and back and green-black elsewhere; the  hen is rusty brown with speckled neck and minimal comb.</p><p>junior college or community college Educational institution that  provides up to two years of COLLEGE-Ievel academic, technical, and voca�  tional instruction with emphasis on career preparation. Roots of the jun�  ior college may be traced to the Chautauqua movement and other adult-  education programs created after the American Civil War. The first junior  college opened in Joliet, Ill., in 1901. The vast majority of junior colleges  are publicly supported; called community colleges, they offer a variety of  flexible programs that are often nontraditional in style and content. They  have pioneered in offering part-time study, evening sessions, instruction  by television, weekend workshops, and other services for members of  their communities. Students rarely live on campus. Graduates of junior or  community colleges ordinarily earn  an associate�s degree. They then  transfer to a four-year college or  enter the workforce.

Juvenile leaves are needle�</p><p>like; mature leaves are awl-shaped, spreading, and arranged in pairs or in  whorls of three. Common juniper (7. communis ) is a sprawling shrub  whose fragrant, spicy-smelling berries are used to flavour foods and alco�  holic beverages, particularly gin. The fragrant wood of eastern red cedar  (7. virginiana ) is made into cabinets, fence posts, and pencils. 7. horizon�  talis is a popular U.S. ornamental creeping juniper, and wood of the  Mediterranean Phoenician juniper (7. phoenicea ) is burned as incense.</p><p>junk Classic Chinese sailing vessel of ancient unknown origin, still in  wide use.

Junk  bonds can be identified through the  lower grades assigned by rating ser�  vices (e.g., BBB instead of AAA for  the highest quality bonds). Because  the possibility of default is great,  junk bonds are usually considered  too risky for investment by the large institutional investors (savings and  loan associations, pension funds, insurance companies, and mutual funds)  that provide U.S. corporations with much of their investment capital. Junk  bonds are often issued by smaller, newer companies.</p><p>Juno In Roman religion, the chief goddess and female counterpart of Jupi�  ter. She was identified with the  Greek goddess Hera. With Jupiter  and Minerva she was a member of  the Capitoline triad of deities tradi�  tionally introduced into Rome by the  Etruscans. She was connected with  all aspects of the lives of women,  particularly marriage. Individual�  ized, she became a female guardian  spirit; as every man had his genius,  so every woman had her juno. Her  temple in Rome eventually housed  the Roman mint, and she was  invoked as the savior of the state.</p><p>Her sacred bird was the peacock.</p><p>Jupiter or Jove Chief god of  ancient Rome and Italy. Like his  Greek counterpart, Zeus, he was wor�  shiped as a sky god. With Juno and  Minerva he was a member of the  triad of deities traditionally believed  to have been introduced into Rome  by the Etruscans. Jupiter was associ�  ated with treaties, alliances, and  oaths; he was the protecting deity of  the republic and later of the reigning  emperor. His oldest temple was on  the Capitoline Hill in Rome. He was  worshiped on the summits of hills  throughout Italy, and all places  struck by lightning became his prop�  erty.

Jupiter has more than 60 moons (see Galilean satellite) and a dif�  fuse ring system discovered in 1979 by the Voyager spacecraft. The planet  is a gas giant, composed mainly of hydrogen and helium in proportions  near those of the Sun, which it orbits every 11.9 years at an average dis�  tance of 483 million mi (778 million km). Its rapid rotation (9 hr 55.5  min) acts on electric currents to give it the largest magnetic field of any  of the planets and causes intense storms, including one that has lasted  hundreds of years (the Great Red Spot). Little is known of its interior, but  it is presumed to have a deep layer of metallic hydrogen and a dense core.  Its central temperature is estimated to be 45,000 �F (25,000 �C); it radi�  ates twice as much heat as it receives from the Sun, probably largely heat  left over from its formation.</p><p>Jupiter Dolichenus \,do-li-'ka-n3s\ God of a Roman mystery cult. He  was originally a Hittite-Hurrian god of fertility and thunder worshiped at  Doliche in Anatolia. He also became identified with the Zoroastrian god  Ahura Mazda as a lord of the universe. Returning legions carried his cult  to Rome, where it became popular in the 2nd-3rd century ad. In Roman  mystery religion he was believed to control military success and safety. He  was usually represented standing on a bull holding a double ax and thun�  derbolt.</p><p>Jura Mountains Mountain range, central Europe. It extends 225 mi  (360 km) along the boundary of France and Switzerland. Its highest peak  is Mount Neige, some 5,650 ft (1,700 m) high, located in France. Its  western slopes are the source of the Doubs and Ain rivers in France.</p><p>Jurassic Period Interval of geologic time, 206-144 million years ago,  that is one of the three major divisions of the Mesozoic Era, preceded by  the Triassic Period and followed by the Cretaceous. During the Jurassic,  Pangea began to break up into the present-day continents. Marine inver�  tebrates flourished, and large reptiles dominated many marine habitats.  On land, ferns. Mosses, cycads, and conifers thrived, some developing  flowerlike structures in place of cones. The dinosaurs rose to supremacy  on land, and by the end of the Jurassic the largest species had evolved.  Archaeopteryx, the first primitive bird, appeared before the end of the  period. Early mammals, tiny shrewlike creatures that appeared near the  close of the preceding Triassic, managed to survive and evolve.</p><p>Jurchen dynasty See Juchen dynasty</p><p>jurisdiction Authority of a court to hear and determine cases. This  authority is constitutionally based. Examples of judicial jurisdiction are:  appellate jurisdiction, in which a superior court has power to correct legal  errors made in a lower court; concurrent jurisdiction, in which a suit might  be brought to any of two or more courts; and federal jurisdiction. A court  may also have authority to operate within a certain territory. Summary  jurisdiction, in which a magistrate or judge has power to conduct pro�  ceedings resulting in a conviction without jury trial, is limited in the U.S.  to petty offenses.</p><p>jurisprudence Science or philosophy of law. Jurisprudence may be  divided into three branches: analytical, sociological, and theoretical. The  analytical branch articulates axioms, defines terms, and prescribes the  methods that best enable one to view the legal order as an internally con�  sistent, logical system. The sociological branch examines the actual effects  of the law within society and the influence of social phenomena on the sub�  stantive and procedural aspects of law. The theoretical branch evaluates  and criticizes law in terms of the ideals or goals postulated for it.</p><p>jury In law, a body of individuals selected and sworn to inquire into a  question of fact and to render a verdict according to the evidence. Juries  may deal with questions of law in addition to questions of fact, though  federal juries in the U.S. are usually limited to dealing with questions of  fact. The modem jury can vary in size depending on the proceeding but  usually has either 6 or 12 members. By U.S. law, federal grand juries and  petit juries must be �selected at random from a fair cross-section of the  community in the district or division wherein the court convenes.� State  jury selection varies somewhat. The Supreme Court of the United States has  stated in a series of decisions that a jury is to be composed of �peers and  equals� and that systematic exclusion from a jury of a particular class of  people (e.g., on the basis of sex, skin colour, or ancestry) violates the  equal-protection clause of the 14th Amendment to the Constitution of the  United States and the defendant�s right to a jury trial. A defendant is not,  however, entitled to a jury of any particular composition. See also grand  jury; petit jury; voir dire.</p><p>just-in-time manufacturing (JIT) Production-control system,  developed by Toyota Motor Corp. and imported to the West, that has  revolutionized manufacturing methods in some industries. By relying on  daily deliveries of most supplies, it eliminates waste due to overproduc�  tion and lowers warehousing costs. Supplies are closely monitored and  quickly altered to meet changing demands, and small and accurate resup�  ply deliveries must be made just as they are needed. Because there are  no spares, the components must be free of defects. Plants wholly dedi�  cated to the JIT concept require a logistics staff to schedule production,  balancing product demand with plant capacity and availability of inputs.  JIT has worked most effectively for large automobile manufacturers,  which may have several thousand suppliers feeding parts into 100 facto�  ries that assemble components for 20 assembly lines.</p><p>just war theory Set of conditions under which a resort to war is mor�  ally legitimate (jus ad bellum ); also, rules for the moral conduct of war  (jus in bello ). Among the proposed conditions for the just resort to war  are that the cause be just (e.g., self-defense against an attack or the threat  of imminent attack), that the authority undertaking the war be competent,  that all peaceful alternatives be exhausted, and that there be a reasonable  hope of success. Two of the most important conditions for the just con�  duct of war are that the force used be �proportional� to the just cause the  war is supposed to serve (in the sense that the evil created by the war  must not outweigh the good represented by the just cause) and that mili�  tary personnel be discriminated from innocents (noncombatant civilians),  who may not be killed. The concept of just war was developed in the  early Christian church; it was discussed by St. Augustine in the 4th cen�  tury and was still accepted by Hugo Grotius in the 17th century. Interest  in the concept thereafter declined, though it was revived in the 20th cen�  tury in connection with the development of nuclear weapons (the use of  which, according to some, would violate the conditions of proportional�  ity and discrimination) and the advent of �humanitarian intervention� to  put an end to acts of genocide and other crimes committed within the  borders of a single state.</p><p>justice In philosophy, the concept of a proper proportion between a per�  son�s deserts (what is merited) and the good and bad things that befall or  are allotted to him or her. Aristotle�s discussion of the virtue of justice has  been the starting point for almost all Western accounts. For him, the key  element of justice is treating like cases alike, an idea that has set later  thinkers the task of working out which similarities (need, desert, talent)  are relevant. Aristotle distinguishes between justice in the distribution of  wealth or other goods (distributive justice) and justice in reparation, as,  for example, in punishing someone for a wrong he has done (retributive  justice). The notion of justice is also essential in that of the just state, a  central concept in political philosophy. See also law.</p><p>justice of the peace In Anglo-American legal systems, a local mag�  istrate empowered chiefly to administer justice in minor cases. In the U.S.,  justices of the peace are elected or appointed and hear minor civil mat�  ters and petty criminal cases. They may also officiate at weddings, issue  arrest warrants, deal with traffic offenses, and hold inquests.</p><p>justification In Christian theology, the passage of an individual from  sin to a state of grace. Some theologians use the term to refer to the act  of God in extending grace to the sinner, while others use it to define the  change in the condition of a sinner who has received grace. St. Paul used  the term to explain how people moved from sin to grace through the death  and resurrection of Jesus and not through any human effort. St. Augustine  saw it as an act of God that makes sinners righteous, while Martin Luther  stressed justification through faith alone.</p><p>Justin II (d. Oct. 4, 578) Byzantine emperor (565-78). He tolerated the  Monophysite heresy until 571, then began to persecute its followers. Despite  an alliance with the Franks, Justin lost parts of Italy to the Lombards after  568. He also suffered defeats at the hands of the Avars, to whom he  promised to pay tribute (574), and the Western Turks, who seized lands  in the Crimea. He invaded Persia in 572, but the Persians repulsed his  army and invaded Byzantine territory, capturing Dara in 573. He became  insane, and his general Tiberius (his adopted son) was effective ruler of  the empire after 574.</p><p>Justin Martyr, Saint (b. c. 100, Flavia Neapolis, Palestine�d. c. 165,  Rome; feast day June 1) Early Christian Apologist and theologian. A  pagan bom in Palestine, he studied philosophy before becoming a Chris�  tian in 132, probably at Ephesus. He then spent years as an itinerant  preacher and teacher. One of the earliest Christian Apologists, he was the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Justinian I &#x25BA; juvenile court I 1007</p><p>first to blend Greek philosophy and Christian doctrine. He wrote two  Apologies addressed to Roman emperors, which asserted that Christian  faith can be in harmony with human reason and that Christianity is a purer  form of the truth glimpsed in pagan philosophy. In his Dialogue with Try-  pho he tried to prove the truth of Christianity to a scholarly Jew named  Trypho. While living in Rome, he was denounced as subversive and con�  demned to death.</p><p>Justinian I orig. Petrus Sabbatius (b. 483, Tauresium,  Dardania�d. Nov. 14, 565, Con�  stantinople) Byzantine emperor  (527-565). Determined to regain  former Roman provinces lost to bar�  barian invaders, Justinian conquered  the Vandals in northern Africa in 534  and enjoyed an initial victory over  the Ostrogoths in Italy in 540. War  with the Goths, however, lasted  another two decades and brought  great devastation before Justinian  gained control of the whole of Italy  in 562 . He was unable to prevent  Bulgars, Slavs, Huns, and Avars  from carrying out raids along the  empire�s northern frontier. He also  carried on an intermittent war with  Persia until 561. He reorganized the  imperial government and commis�  sioned the reform and codification of  the great body of Roman law known  as the Code of Justinian. His efforts to root out corruption triggered a revolt  in Constantinople in 532 that nearly toppled his government; his wife,  Theodora, helped him put down the revolt. Like all Roman emperors, Jus�  tinian was an active builder, and his many public works projects included  the reconstruction of cities and the construction of the church of Hagia  Sophia, one of the finest and most famous buildings in the world.</p><p>Justinian, Code of Collections of laws and legal interpretations devel�  oped under the sponsorship of the Byzantine emperor Justinian I from 529  to 565. Strictly speaking, they did not constitute a new legal code. Rather,  Justinian�s committees of jurists provided basically two reference works  that contained collections of past laws and extracts of the opinions of the  great Roman jurists. Also included were an elementary outline of the law  and a collection of Justinian�s new laws.</p><p>jute Either of two herbaceous annuals ( Corchorus capsularis and C. oli-  torius, in the linden family), or their fibre. The plants grow 10-12 ft (3^4</p><p>m) high and have long, serrated, tapered, light green leaves and small yel�  low flowers. Jute has been grown and processed in the Bengal area of  India and Bangladesh since ancient times. Its biggest use is in burlap sacks  and bags, which are used to ship and store many agricultural products.  High-quality jute cloths are used as backing for tufted carpets and hooked  rugs. Coarser jute fibres are made into twines, rough cordage, and door�  mats.</p><p>Jutland Danish Jylland Vyue-JanV Peninsula, northern Europe. Form�  ing the Danish mainland and the German state of Schleswig-Holstein, it is  bounded to the west and north by the North Sea. Politically, its name  applies only to the mainland of Denmark. It has an area of 11 ,496 sq mi  (29,775 sq km) and is divided into several administrative regions. In  World War I, the Battle of Jutland was fought off its coast.</p><p>Jutland, Battle of (May 31-June 1, 1916) Only major encounter  between the British and German fleets in World War I, fought in the  Skagerrak, an arm of the North Sea off the coast of Jutland (Denmark).  The battle came to an indecisive end, and both sides claimed victory. Ger�  many destroyed and crippled more ships and men, but Britain retained  control of the North Sea. The tactics of the British admiral John R. Jelli-  coe were criticized at the time, but his strategic victory left the German  high-seas fleet ineffective for the rest of the war.</p><p>Juvenal Vjii-vs-naA orig. Decimus Junius Juvenalis (b. c. ad</p><p>55�d. 130) Roman poet. He is believed to have been born into a wealthy  family, to have become an army officer, and to have grown embittered by  his failure to receive a promotion. He is chiefly known for his 16 Satires,  indignant attacks on human brutality and folly, particularly the corruption  of Roman society under Domitian and his more humane successors Nerva,  Trajan, and Hadrian. Juvenal�s verses are technically fine, vivid, and often  ruthless, and they have been admired and imitated since the 5th century.  Many of his phrases and epigrams (�bread and circuses,� �who will guard  the guards themselves?� etc.) have entered common parlance.</p><p>juvenile court Special court handling problems of delinquent,  neglected, or abused children. Two types of cases are processed by a  juvenile court: civil matters, often concerning care of an abandoned or  impoverished child, and criminal matters, arising from antisocial behav�  iour by the child. Most statutes provide that all persons under a given age  (often 18 years) must first be processed by the juvenile court, which can  then, at its discretion, assign the case to an ordinary court. Before the cre�  ation of the first juvenile court, in Chicago in 1899, and the subsequent  creation of other such courts in the United States and other countries (e.g.,  Canada in 1908; England in 1908; France in 1912; Russia in 1918; Poland  in 1919; Japan in 1922; and Germany in 1923), juveniles were tried in  the same courts as adults.</p><p>Justinian I, detail of a mosaic, 6th cen�  tury; in the Basilica of San Vitale,  Ravenna</p><p>AUNARI-GIRAUDON FROM ART RESOURCE</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1008 I K2 &#x25BA; kachina</p><p>K2 or Dapsang \,dap-'sang\ Mountain in the Karakoram Range.

It was discovered and measured in 1856 by Col. T.G. Montgom�  erie and was given the symbol K2 because it was the second peak mea�  sured in the Karakoram Range. In 1954 the Italians Achille Compagnoni  and Lino Lacedelli became the first climbers to reach its summit.</p><p>Ka'bah Most sacred Muslim shrine, located near the centre of the Great  Mosque in Mecca. All Muslims face toward it in their daily prayers. The  cube-shaped structure, made of gray stone and marble, has its corners  roughly oriented to the points of the compass; the interior contains only  pillars and silver and gold lamps. Pilgrims to  Mecca walk around the Ka'bah seven times and  on its eastern side touch the Black Stone of Mecca,  which may date from the pre-Islamic religion of the  Arabs. Tradition holds that the Ka'bah was built by  Abraham and Ishmael. In 630 Muhammad purged the  place of its pagan idols and rededicated it to Islam.</p><p>Kabalega National Park \,ka-ba-Ta-ga\ National  park, northwestern Uganda. Established in 1952, it  occupies 1,483 sq mi (3,840 sq km) of rolling grass�  land. Its central feature is the Kabalega Falls on the  lower Victoria Nile River. The falls are about 20 ft (6  m) wide and drop 130 ft (40 m) in the first of three  cascades.</p><p>Kabbala or Cabbala \ka-'ba-b\ Jewish mysticism as  it developed in the 12th century and after. Essen�  tially an oral tradition, it laid claim to secret wis�  dom of the unwritten Torah communicated by  God to Adam and Moses. It provided Jews with a direct approach to God,  a notion regarded as heretical and pantheistic by Orthodox Judaism. A  major text was the 12th-century Book of Brightness, which introduced the  doctrine of transmigration of souls to Judaism and provided Kabbala with  extensive mythical symbolism. In 13th-century Spain the tradition  included the Book of the Image, which asserted that each cycle of history  had its own Torah, and the Book of Splendour, which dealt with the mys�  tery of creation. In the 16th century the centre of Kabbala was Safed,  Galilee, where it was based on the esoteric teachings of the greatest of  all Kabbalists, Isaac ben Solomon Luria. The doctrines of Lurianic Kab�  bala, which called for Jews to achieve a cosmic restoration (Hebrew:  tiqquri) through an intense mystical life and an unceasing struggle against  evil, were influential in the development of modern Hasidism.</p><p>Kabila Xks-'be-loV Laurent (Desire) (b. 1939, Jadotville, Belgian  Congo�d. Jan. 18?, 2001, en route to Harare, Zimb.) Rebel leader and  president (1997-2001) of Congo (Kinshasa). He attended schools abroad,  including military school in China, before participating in several  Marxist-inspired uprisings in Zaire in the 1960s and �70s. He later became  a trader in precious minerals and ivory. In the Rwandan civil war, Kabila  collaborated with Paul Kagame in attacking Hutu guerrilla groups in Zaire  as well as Zairean government forces. His troops ousted Mobutu Sese Seko  in 1997, and Kabila proclaimed himself president and renamed the coun�  try. His repressive policies soon led to a new and larger war, in which  many African states sent troops and aid to both sides. His assassination  was apparently engineered by his own officers; his son Joseph (b. 1971)  succeeded him.</p><p>Kabir \ko-'bir\ (b. 1440, Varanasi, Jaunpur, India�d. 1518, Maghar)  Indian mystic and poet. A weaver who lived in Benares, he preached the  essential oneness of all religions and was critical of both Hinduism and  Islam for meaningless rites and mindless repetition. From Hinduism he  accepted the ideas of reincarnation and the law of karma but rejected  idolatry, asceticism, and the caste system. From Islam he accepted the  idea of one God and the equality of all men. Revered by both Hindus and  Muslims, he is also considered a forerunner of Sikhism, and some of his  poetry was incorporated into the Adi Granth. His ideas led to the found�  ing of several sects, including the Kabir Panth, which regards Kabir as  its principal guru or as a divinity.</p><p>kabuki \ka-'bii-ke\ Popular Japanese entertainment that combines  music, dance, and mime in highly stylized performances. The word is  written using three Japanese characters �ka (�song�), bu (�dance�), and  ki (�skill�). Kabuki dates from the end of the 16th century, when it devel�  oped from the nobility�s NO theatre and became the theatre of townspeople.</p><p>In its early years it had a licentious reputation, its actors often being pros�  titutes; women and young boys were consequently forbidden to perform,  and kabuki is today performed by an adult all-male cast. Its texts, unlike  no texts, are easily understood by its audience. The lyrical but fast-moving  and acrobatic plays, noted for their spectacular staging, elaborate cos�  tumes, and striking makeup in place of masks, are vehicles in which the  actors demonstrate a wide range of skills. Kabuki employs two musical  ensembles, one onstage and the other offstage. It shares much of its rep�  ertoire with bunraku, a traditional puppet theatre.</p><p>Kabul \'ka-bol\ City (pop., 1993 est.: 700,000), capital of Afghanistan.  Located on the Kabul River in a valley strategically located between moun�  tain passes, it has existed for some 3,500 years. It  became the capital of the Mughal dynasty in the  16th century, and it remained under Mughal rule  until 1738, when it was captured by the Iranian con�  queror Nadir Shah. Kabul has been the capital of Afghanistan  since 1776. When the Soviet Union invaded Afghanistan in  1979, it established a military command in Kabul. After the Soviet  withdrawal in 1989, factional fighting among Afghan guerrillas con�  tinued intermittently and the city suffered widespread destruction.  In 1996 the Taliban captured Kabul and imposed an austere form  of Islamic rule.

For  much of its course, the river is tapped for irrigation.</p><p>Kabyle \k9-'bil\ Berber people of northeastern Algeria. Most are Mus�  lim, though a few are Christian. They are predominantly agricultural,  growing grains and olives and herding goats. Village government is run  by an assembly of adult males.

Great  Rann, occupies an area of 7,000 sq mi (18,000 sq km) in Gujarat state,  India. The eastern section, Little  Rann, occupies 2,000 sq mi (5,100  sq km) of Gujarat. Originally an  extension of the Arabian Sea, it has  been closed off by centuries of silt�  ing.

He attended Har�  vard University and earned a doctorate in mathematics from the Univer�  sity of Michigan. He taught at the University of Califomia-Berkeley  (1967-69) then abruptly left for rural Montana, where he lived in a tiny,  isolated shack. Over a period of 17 years, he sent mail bombs to people  he perceived as enemies of humanity, most of them professors and  researchers in science and technology, killing 3 people and injuring 23.  His manifesto excoriating industrial society was published widely in  1995.

He joined the then-illegal Communist Party in 1931 and entered  the Hungarian Politburo in 1945. In 1950 he came into conflict with the  Stalinists and was expelled from the party and jailed (1951-53). Reha�  bilitated in 1954, he joined the short-lived government of Nagy Imre.  After Soviet troops took over the country in 1956, Kadar formed a new  government with Soviet backing and quelled a popular revolt. He later  convinced the Soviet Union to withdraw its troops and allow Hungary a  modicum of internal independence.</p><p>Kadare, Ismail (b. Jan. 28, 1936, Gjirokaster, Alb.) Albanian novelist  and poet. The son of a post-office worker, Kadare became a journalist.  Unhappy with the political environment in Albania, he eventually made  his home in Paris. Among his better-known works are the novels The  General of the Dead Army (1963), about post-World War II Albania, and  The Castle (1970), which explores Albanian nationalism. The stories in  Elegy for Kosovo (1999) concern a 14th-century battle between Balkan  leaders and the Ottoman Empire. He was the only Albanian writer to have  an international following in the 20th century.</p><p>Kaddish Vka-dish\ Jewish doxology (hymn of praise to God) that is  usually recited in Aramaic at the end of principal sections of all synagogue  services. Originally recited in the rabbinical academies, it later became a  regular feature of the synagogue service. The prayer expresses, in addi�  tion to the praise of God, the plea for the speedy realization of the mes�  sianic age. The prayer�s association with the arrival of the messiah and  the resurrection of the dead led to its becoming the prayer of mourners.  There are four other forms of the Kaddish used in worship services.</p></section><section><p>Kadesh Vka-,desh\ Ancient city, western Syria. Located just southwest  of modern Hims, it was seized by the Egyptian king Thutmose III in the  15th century bc. It remained an outpost of Egypt until it came under Hit-  tite rule in the mid-14th century bc. The Egyptian king Seti I captured the  city, and in 1275 bc it was the scene of a battle between Ramses II and the  Hittite Muwatallis.

Kafka�s posthumous reputation and influence have been enor�  mous, and he is regarded as one of the great European writers of the 20th  century.</p><p>Kafue \ka-'fii-a\ National Park National park, south-central Zam�  bia. Located west of Lusaka, it was established in 1950. It occupies an  area of 8,650 sq mi (22,400 sq km) and consists of a vast plateau, situ�  ated along the middle reaches of the Kafue River. The park is noted for its  lush vegetation and abundant wildlife, including hippopotamuses, zebras,  elephants, black rhinoceroses, and lions.

It is one of Zambia�s major rivers, and its waters are  used for irrigation and hydroelectric power.</p><p>Kagame \ka-'ga-ma\, Paul (b. October 1957, Rwanda) President of  Rwanda from 2000. An ethnic Tutsi, Kagame grew up in exile in Uganda,  where in 1986 he helped overthrow Milton Obote in favour of Yoweri  Museveni. In 1990 he helped direct an unsuccessful coup in Rwanda, and  following the 1994 genocide that left almost one million Rwandans dead  (most of them Tutsi), he assumed control of the joint Tutsi-Hutu opposition  forces that soon controlled all of Rwanda. In July 1994 he was named vice  president and minister of defense under Hutu president Pasteur Bizimungu.  After Bizimungu resigned in 2000, Kagame was named president. In 1997  he was instrumental in the overthrow of Mobutu Sese Seko in neighbouring  Zaire (Congo) and the installation of Laurent Kabila as president.</p><p>Kaganovich \k9-g9-'no-vich\, Lazar (Moiseyevich) (b. Nov. 22,  1893, Kabany, near Kiev, Ukraine, Russian Empire�d. July 25, 1991,  Moscow, Russia, U.S.S.R.) Soviet political leader. He joined the Bolshe�  viks in 1911 and became head of the Soviet government of Tashkent in  1920. As head of the Moscow party organization (1930-35), he brought  it firmly under Joseph Stalin�s control and with Vyacheslav Molotov formed  the core of Stalin�s �post-purge� Politburo (see purge trials). Until 1953  he was largely responsible for heavy industry in the Soviet Union. Under  Nikita Khrushchev, he held administrative posts, but he opposed  de-Stalinization and joined the unsuccessful attempt to depose Khrush�  chev in 1957, as a result of which he lost all his offices.</p><p>Kagera River \ka-'ga-ra\ River, northwestern Tanzania.

Kagura dances dedicated to native deities  are a reenactment of the propitiatory dance that lured the sun goddess  Amaterasu from her cave in ancient myth. Largely unchanged for the past  1,500 years, the dances are performed to the accompaniment of chants,  drums, brass gongs, and flutes. The music is of two types: one to praise  the spirits or seek their aid, the other to entertain the gods.</p><p>Kahlo Vka-lo\ (y Calderon de Rivera), (Magdalena Carmen)  Frida (b. July 6, 1907, Coyoacan,</p><p>Mex.�d. July 13, 1954, Coyoacan)</p><p>Mexican painter. The daughter of a  German Jewish photographer, she  had polio as a child and at 18 suffered  a serious bus accident. She subse�  quently underwent some 35 opera�  tions; during her recovery, she taught  herself to paint. She is noted for her  intense self-portraits, many reflecting  her physical ordeal. Like many artists  working in post-revolutionary  Mexico, Kahlo was influenced by  Mexican folk art; this is apparent in  her use of fantastical elements and  bold use of colour, and in her depic�  tions of herself wearing traditional  Mexican, rather than European-style,  dress. Her marriage to painter Diego  Rivera (from 1929) was tumultuous  but artistically rewarding. The Surre�  alists Andre Breton and Marcel Du�  champ helped arrange exhibits of her  work in the U.S. and Europe, and  though she denied the connection, the  dreamlike quality of her work has  often led historians to identify her as a Surrealist. She died at 47. Her house  in Coyoacan is now the Frida Kahlo Museum.</p><p>Kahn, Albert (b. March 21, 1869, Rhaunen, Westphalia�d. Dec. 8,  1942, Detroit, Mich., U.S.) German-bom U.S. industrial architect. In 1904  he received a commission for the Packard Motor Car Co. auto factory; his  design, with its reinforced concrete frame, represented an innovative  departure from traditional masonry factory construction. Kahn was the  principal architect for most of the large American automobile companies  for 30 years. His firm designed more than a thousand projects for Ford,  among them the fabrication and assembly plant in River Rouge, Mich.,  which was one of the largest industrial complexes in the world. By 1937 his  firm was producing 19% of all architect-designed industrial buildings in  the U.S., and he received commissions for factories, foundries, and ware�  houses from all continents. Kahn�s firm designed 521 factories in the  U.S.S.R. and trained more than a thousand Soviet engineers during the  1930s.</p><p>Kahn, Herman (b. Feb. 15,1922, Bayonne, N.J., U.S.�d. July 7,1983,  Chappaqua, N.Y.) U.S. physicist and strategist. He studied at the California  Institute of Technology and joined the RAND Corp., where he studied the  application to military strategy of new analytic techniques such as game  theory, operations research, and systems analysis. He won public notice  with On Thermonuclear War (1960), in which he contended that thermo�  nuclear war differs only in degree from conventional war and ought to be  analyzed and planned in the same way. In 1961 he established the Hudson  Institute for research into matters of national security and public policy.</p><p>Kahn, Louis l(sadore) (b. Feb. 20, 1901, Osel, Estonia, Russian  Empire�d. March 17, 1974, New York, N.Y., U.S.) Estonian-born U.S.  architect. He came to the U.S. as a child and graduated from the Univer�  sity of Pennsylvania. One of the century�s most original architects, Kahn  turned from the International Style to a timeless, elegant Brutalism evoca�  tive of ancient ruins. His Richards Medical Research Building (1960-65)  at the University of Pennsylvania isolated �servant� spaces (stairwells,  elevators, vents, and pipes) in four towers distinct from �served� spaces  (laboratories and offices). His fortresslike National Assembly Building in  Dhaka, Bangl. (1962-74), utilized geometric shapes to admit light to its</p><p>inner domed mosque. Like R. Buckminster Fuller, Kahn was concerned  about wasteful use of natural resources; his urban-planning schemes pro�  posed geodesic skyscrapers and huge car �silos.� He taught at Yale Uni�  versity (1947-57) and the University of Pennsylvania (1957-74), where  appreciation for his intellect gained him a cult status.</p><p>Kahneman, Daniel (b. March 5, 1934, Tel Aviv, Israel) Israeli-born  psychologist. He attended Hebrew University (B.A., 1954) in Jerusalem  and the University of California, Berkeley (Ph.D., 1961). He later taught at  such institutions as Princeton University and was on the editorial board of  several academic journals. In the late 1960s he began conducting research  to increase understanding of how people make economic decisions. His  work with Amos Tversky on decision making under uncertainty resulted in  the formulation of a new branch of economics, prospect theory. Using sur�  veys and experiments, Kahneman showed that people were incapable of  analyzing complex decision situations when the future consequences were  uncertain. Instead, they relied on heuristic, or rule-of-thumb, shortcuts. In  2002 he shared the Nobel Prize for Economics with Vernon L. Smith.</p><p>Kaibara Ekiken \'kl-ba-ra-e-'ke- 1 ken\ (b. Dec. 17, 1630, Fukuoka,  Japan�d. Oct. 5, 1714, Japan) Japanese philosopher, travel writer, and  pioneer botanist. Trained as a physician, he left the medical profession in  1657 to study the Neo-Confucian writings of Zhu Xi. He wrote about 100  philosophical works, which stressed the hierarchical nature of society and  translated Confucian doctrine into terms understood by Japanese of all  social classes. His writings include The Great Learning for Women , a tract  on obedience long considered the most important ethical text for Japa�  nese women. He is regarded as the father of botany in Japan.</p><p>Kaieteur VkI-9-,tur\ Falls Cataract on the Potaro River, west-central  Guyana.

In the 4th century bc it became the capital of  the state of Wei, and the first of its canals was built. It was destroyed by  the Qin dynasty in the late 3rd century bc, and until the 5th century ad it  was only a market town. It became an important commercial centre in the  7th century, enriched by traffic along the Grand Canal, and it was the  capital of the Five Dynasties and the Song dynasty. Kaifeng was the site of  China�s only well-documented Jewish community (12th-16th centuries).</p><p>Kaikei Vkl-,ka\ (fl. 1183-1236, Japan) Japanese sculptor who helped  establish the traditional pattern of Buddhist sculpture. His technique,  known as the Anami style, is noted for its gentleness and grace. Together  with his teacher, Kokei, and his colleague Unkei, he made statues for the  temples of Kofuku and Todai in Nara, Japan�s ancient capital. He later  became a monk and assumed the name Anami Butsu.</p><p>Kairouan \ker-'wan\ or Al-Qayrawan City (pop., 1994: 102,600),  northeastern Tunisia. A religious centre of Islam, it was founded in 670 by  the Arab general Sid! �Uqbah and became the first Arab city in the Ma�  ghrib. It was chosen as the Maghrib capital by the Aghlabid dynasty c. 800.  It served as an administrative, commercial, religious, and intellectual cen�  tre under the Fatimid and Zlrid dynasties. The rise of Tunis, the new capi�  tal, led to Kairouan�s decline and its devastation by Bedouin in the 11th  century. It is the site of the 9th-century Great Mosque of the Qayrawan,  one of the city�s 150 mosques.</p><p>Kaiser Vkl-zoiA, Henry J(ohn) (b. May 9, 1882, Sprout Brook, N.Y.,  U.S.�d. Aug. 24, 1967, Honolulu, Hawaii) U.S. industrialist and founder  of more than 100 companies, including Kaiser Aluminum, Kaiser Steel,  and Kaiser Cement and Gypsum. He undertook his first public-works  projects beginning in 1914, eventually building dams in California, levees  on the Mississippi River, and highways in Cuba. Between 1931 and 1945  he organized combinations of construction companies to build the Hoover,  Bonneville, and Grand Coulee dams and other large public projects. Dur�  ing World War II he ran seven shipyards, making steel in an integrated  steel mill and using assembly-line production to build ships in less than  five days. He established the first health maintenance organization, the  Kaiser plan, for his shipyard employees; it served more than a million  people and became a model for later federal programs. In the postwar era  he dealt profitably in aluminum, steel, and automobiles.</p><p>Kakinomoto Hitomaro Vka-ke-no-.mo-to- 'he-t6-,ma-r6\ known as  Hitomaro (d. 708, Japan) Japanese poet.

Apart from the dynastic name and per�  haps a belief in common ancestry, there is little in known sources to con�  nect them. The earliest known Kalacuri family ruled c. 550-620 in central  and western India; its power ended with the rise of one branch of the  Calukyas. The rise of another Kalacuri dynasty (1156-81), centred in Kar�  nataka, coincided with the rise of the Lingayat, or Virashaiva, Hindu sect.  The best-known Kalacuri family ruled in central India with its base at the  ancient city of Tripuri (modern Tewar); it originated in the 8th century,  expanded significantly in the 11th century, and declined in the 12th�13th  centuries.</p><p>Kalahari Desert \,ka-la-'ha-re\ Desert region, southern Africa. It cov�  ers an area of 360,000 sq mi (930,000 sq km) and lies mostly in Botswana  but also occupies portions of Namibia and South Africa. It was crossed  by the British explorers David Livingstone and William C. Oswell in 1849.  Although the region has no permanent surface water apart from the Boteti  River, it supports trees, low scrub, and grasses as well as abundant wild�  life. It includes the Kalahari Gemsbok National Park and the Gemsbok  National Park.</p><p>kalam \k3-'lam\ Islamic speculative theology. It arose during the  Umayyad dynasty over varying interpretations of the Qur�an and over ques�  tions the Qur�an provoked, including those on predestination, free will,  and the nature of God. The most prominent early school was the 8th-  century Mu'tazilah, which asserted the supremacy of reason, championed  free will, and rejected an anthropomorphic characterization of God. The  10th-century school of Ash'ariyyah moved kalam back toward traditional  faith, accepting, for example, the eternal, uncreated nature of the Qur�an  and its literal truth. The school also represented the successful adaptation  of Hellenistic philosophical reasoning to Muslim orthodox theology.</p><p>Kalamukha See Kapalika and Kalamukha</p><p>kalanchoe \,ka-l9n-'ko-e\ Any of several species of succulent plants  that make up the genus Kalanchoe in</p><p>the stonecrop family(Crassulaceae).  popular for their easy indoor culture.</p><p>Potted K. blossjcliliana plants are  marketed widely for their winter-</p><p>blooming bright red and orange (� ^ j *</p><p>llowers. which may remain fresh for j�r $7 �&#x25A0; *'&#x25A0;</p><p>as long as eight weeks.

He served in a German  regiment of the French infantry from 1743. In 1768 the French sent him  on a secret mission to the American colonies to determine their attitude  toward Britain. In 1776 he obtained a commission in the Continental  Army. He reached Philadelphia in July 1777 and was eventually appointed  a major general by the Continental Congress. He became a strong admirer  of Gen. George Washington and served with him at Valley Forge. In 1780</p><p>he joined Gen. Horatio Gates at Camden, S.C., in an abortive attack on  British forces.

Common (or Scotch) and  Buda kale have stems up to 2 ft (60  cm) long that carry a rosette of elon�  gated, dark bluish green, wavy or  frilled leaves. Grown mainly for  autumn and winter harvest because  cold weather improves the quality of  this hardy vegetable, kale is usually  served cooked. It is highly nutritious.</p><p>See also coliard.</p><p>kaleidoscope Optical device  consisting of mirrors that reflect  images of bits of coloured glass or  other objects in a symmetrical geo�  metric design through a viewer. The  design may be changed endlessly by  rotating the section containing the  loose fragments. A simple kaleido�  scope consists of two thin, wedge-  shaped mirror strips touching along  a common edge. The mirrors are  enclosed in a tube with a viewing  eyehole at one end. At the other end  is a thin, flat box that can be rotated; it is made from two glass disks, the  outer one ground to act as a diffusing screen. In this box are pieces of  coloured glass, beads, etc. When the box is turned, the objects inside  tumble into an arbitrary grouping, and when the diffusing screen is illu�  minated, the sixfold or eightfold multiplication creates a striking sym�  metrical pattern. The kaleidoscope was invented by Sir David Brewster  c. 1816.</p><p>Ka leva la Yka-la-,va-la\ Finnish national epic. It was compiled by Elias  Lonnrot from the songs and ballads of Finland�s oral tradition and pub�  lished in complete form in 1849. Kalevala, the dwelling place for the  poem�s chief characters, is also a poetic name for Finland, meaning �land  of heroes.� The epic contains a creation story and adventures of legend�  ary heroes. The main character is Vainamoinen, a musician and seer of  supernatural origins. Other characters include Ilmarinen, a smith who  forged the lids of heaven; Lemminkainen, a warrior-adventurer and  charmer of women; and Louhi, the female ruler of a land in the north.  Though the Kalevala depicts conditions during the pre-Christian era, it  also seems to foretell the decline of the old religions.</p><p>Kalf \'kalf\, Willem or Willem Kalff (b. Nov. 3, 1619, Rotterdam,  Neth.�d. July 31, 1693, Amsterdam) Dutch painter. He is among the  best-known Dutch painters of still lifes. His early works depict kitchen  interiors, with such elements as  gourds and pots strewn on the floor.</p><p>His later paintings feature luxurious,  expensive objects such as Venetian  glass and Chinese porcelain, painted  with restraint and richness of texture.</p><p>Though his still lifes followed an  established formula, Kalf greatly  enriched the genre with his use of  simple composition, dark back�  ground, and acutely perceived high�  lights. In restraint and richness of  texture, Kalf�s still lifes were sel�  dom, if ever, matched. Works such as  Still Life with a Nautilus Cup (c.</p><p>1660) were popular among Amster�  dam�s wealthy.</p><p>Kali Destructive and devouring  Hindu goddess.

Noted  for killing the demon Raktavija, she is usually depicted as a hideous,  black-faced hag smeared with blood. In her four hands she holds, vari�  ously, a sword, a shield, the severed head of a giant, or a noose for stran�  gling. Nearly naked, she wears a garland of skulls and a girdle of severed  hands. She is often shown standing or dancing on her husband, Shiva. Until  the 19th century the thugs of India worshiped Kali and offered their vic�  tims to her. In the late 20th century she became a symbol of feminine  empowerment in some circles.</p><p>Kalidasa \,ka-le-'da-sa\ (fl. c. 5th century) Indian poet and dramatist.  Little is known about him; his poems suggest that he was a Brahman  (priest). Many works are traditionally ascribed to him, but scholars have  identified only six as genuine and one more as likely. The Sanskrit drama  The Recognition of Shakuntala, his most famous creation, is traditionally  judged the major Indian literary effort of any period, and Kalidasa is  regarded as perhaps the greatest of all Indian writers.</p><p>Kalinga Ancient kingdom, northeastern India. It corresponds to the area  of modem northern Andhra Pradesh, most of Orissa, and a portion of  Chhattisgarh. It was conquered by Mahapadma, the founder of the Nanda  dynasty, in the 4th century bc. Beginning in the mid-11th century ad, the  Eastern Ganga dynasty assumed control. The temple of the sun-god at  Konarak was built in the 13th century by Narasimha I. The dynasty col�  lapsed when the sultan of Delhi invaded Kalinga from the south in 1324.</p><p>Kalinin Vko-'le-nyonV Mikhail (Ivanovich) (b. Nov. 19, 1875,  Verkhnyaya Troitsa, Russia�d.

After the Russian Revolution of 1917 he served as mayor of Petro-  grad (St. Petersburg). In 1919 he became chair of the central executive  committee of the All-Russian Congress of Soviets, and thus titular head  of the Soviet state, a position he kept until his death. From 1925 he was  a member of the Politburo and supported Joseph Stalin in crucial votes,  thus retaining his high party office.</p><p>Kaliningrad \k3-'le-nin-,grat \formerly Konigsberg Vkoe-niks-.berkV  City (pop., 1999 est.: 427,200), western Russia, situated on the Pregolya  River.

Virtually destroyed by Soviet forces  during World War II, it came under the sovereignty of the U.S.S.R. and  was rebuilt in 1946 as Kaliningrad. It is the seat of the University of  Kaliningrad and the birthplace of Immanuel Kant.</p><p>Kalliope See Calliope</p><p>Kalmar \'kal-,mar\ Union (1397-1523) Scandinavian union that joined  the kingdoms of Norway, Sweden, and Denmark under the rule of a single  monarch. Margaret I had become regent of the three kingdoms by 1388;  she chose her grandnephew Erik of Pomerania to become their king, and  he was crowned at Kalmar, Swed., in 1397. Each country kept its own  laws, customs, and administration. Sweden rebelled and claimed inde�  pendence under Gustav I Vasa in 1523, and Norway became a Danish  province in 1536.</p><p>Kaloyan \'ka-lo-yan\ or Kalojan (d. Oct. 1207, near Thessaloniki)  Tsar of Bulgaria (1197-1207). The younger brother of the founders of the  Second Bulgarian Empire, Kaloyan sought to maintain Bulgarian inde�  pendence. Although he recognized papal authority and was crowned by  papal legates in 1204, Kaloyan reverted to Orthodoxy not long after his  coronation. He proposed an alliance with the armies of the Fourth Cru�  sade but then led a Bulgarian-Greek uprising in the Balkan Peninsula that  defeated the Crusaders at Adrianople (1205) and resulted in the capture  of Baldwin I, the Latin emperor. Kaloyan�s success against the Crusaders  contributed to the ultimate demise of the Latin empire of Constantinople.  He died besieging Thessaloniki during his continuing struggle to  expanded the empire.</p><p>Kama In Indian mythology, the god of love. In the Vedic age he per�  sonified cosmic desire or the creative impulse, and he was called the first�  born of primeval chaos. He was later often depicted as a handsome youth  attended by heavenly nymphs, who shot love-producing flower arrows  from a sugarcane bow. He was once killed by Shiva, who was enraged  when Kama disturbed his meditation on a mountaintop, but the great god  later relented and brought Kama back to life.</p><p>Kama River River, west-central Russia. The largest tributary of the  Volga River, it rises in Udmurtiya and flows for 1,122 mi (1,805 km) until  it enters the Volga below Kazan. Navigation is possible for about 955 mi  (1,535 km). It is one of the most important rivers of Russia, historically  as the route to the Urals and Siberia and economically as part of the vast  Volga system of waterways.</p><p>Kamakura \,ka-ma-'kur-a\ period (1192-1333) Period of Japanese  history marked by the country�s first era of military government. The  Kamakura shogunate was established by Minamoto Yoritomo after his  1185 defeat of a rival warrior family, the Taira (see Taira Kiyomori); its  headquarters was in Kamakura. To assert his authority, Yoritomo had jito  (stewards) assigned to all the estates ( shOen ) in the land to collect taxes,  and shugo (protectors) assigned to one or more provinces to lead them in  times of war. This system was improved by the Hojo family, which took  control of the shogunate on Yoritomo�s death. The creation of the  Kamakura shogunate marks the start of Japan�s medieval or feudal period,  characterized by a warrior ethic of duty, loyalty, and stoicism. Many ele�  ments of Japanese culture that Westerners now associate with the  country�including Zen Buddhism, samurai (warriors), seppuku (ritual dis-  embowelment), and the tea ceremony �date from this period. The True  Pure Land and Nichiren sects of Buddhism, which emphasized salvation  through faith alone, provided solace to the masses, while tales of warrior  exploits provided them with entertainment.

A member of the Bol�  sheviks from 1903, he worked with Vladimir Ilich Lenin in Europe (1909-14),  then returned to Russia, where he was arrested and sent to Siberia. After the  Russian Revolution of 1917, he served as head of the Moscow soviet (1919�  25). When Lenin became seriously ill in 1922, Kamenev joined Joseph Sta�  lin and Grigory Y. Zinovyev to form the ruling triumvirate, attacking Leon  Trotsky. In 1925 Stalin shifted his attack to Kamenev and Zinovyev,  removng Kamenev as Moscow party head. In 1926 Kamenev was expelled  from the party after conspiring with Zinovyev and Trotsky against Stalin.  In 1936 he was tried in the first of the purge trials and confessed to fabricated  charges, hoping to save his family. He was executed, and his wife,  Trotsky�s sister, perished in the Gulag.</p><p>Kamerlingh Onnes N.ka-mor-liq-'o-nosX, Heike (b. Sept. 21, 1853,  Groningen, Neth.�d.

He taught  at the University of Leiden (1882-1923), and in 1884 he founded the  Cryogenic Laboratory (now known by his name) that established Leiden  as the world�s principal research centre for low-temperature physics. He  was the first to produce liquid helium (1908), and he discovered super�  conductivity. He also investigated the equations describing the states of  matter and the general thermodynamic properties of fluids over a wide  range of temperatures and pressures. He was awarded the 1913 Nobel  Prize for Physics.</p><p>kamikaze \,ka-mi-'ka-ze\ Any of the Japanese pilots in World War II  who made deliberate suicidal crashes into enemy targets, usually ships.  The word means �divine wind,� a reference to a typhoon that dispersed a  Mongol invasion fleet threatening Japan from the west in 1281. The prac�  tice was most prevalent in the final year of the war. Most kamikaze planes  were ordinary fighter aircraft or light bombers, usually loaded with bombs  or extra gasoline tanks before their suicidal dive. Such attacks sank 34  ships and damaged hundreds of others; at Okinawa they inflicted the  greatest losses ever suffered by the U.S. Navy in a single battle, killing  almost 5,000 men.

Kan-  del�s research revealed the role of synaptic transmission in learning and  memory. He showed that weak stimuli give rise to certain chemical  changes in synapses, forming the basis for short-term memory, and that  stronger stimuli cause different synaptic changes, which result in a form  of long-term memory. Along with Paul Greengard and Arvid Carlsson,  Kandel was awarded a Nobel Prize in 2000.

Dec. 4, 1866,  Moscow, Russia�d. Dec. 13, 1944, Neuilly-sur-Seine, France) Russian  painter, a pioneer of pure abstraction in modern painting. Trained in the  law and offered a law professorship, he chose painting instead and set out  for Germany. After art studies in Munich, by 1909 he began his lifelong  pursuit: a kind of painting in which colours, lines, and shapes, freed from  the distracting business of depicting recognizable objects, might evolve  into a visual �language� capable of expressing general ideas and evoking  deep emotions. In his book Concerning the Spiritual in Art (1912) he set  forth these ideas, comparing the expressiveness of forms and colour to  qualities in music. In 1911 he and Franz Marc founded an informally  organized group of like-minded artists called Der Blaue Reiter (�The Blue  Rider�). From 1921 to 1933 he taught at the influential Bauhaus in Weimar;  during this period Kandinsky continued to evolve in the general direction  of geometric abstraction, but with a dynamism and a taste for detail. When  the Nazis closed the Bauhaus, he immigrated to Paris. During this final  period his painting became a synthesis of the organic manner of the  Munich period and the geometric manner of the Bauhaus period. The  visual language that he had been aiming at since at least 1910 turned into  collections of signs that look like almost-decipherable messages written  in pictographs and hieroglyphs. His influence on 20th-century art and  abstract art in general was profound.</p><p>Kandler \'ken-dler\, Johann  Joachim (b. 1706, Fischbach,</p><p>Saxony�d.

He worked mainly in Toronto but traveled as far as the Pacific  coast depicting landscapes, Native American subjects, fur traders, and  missionaries; he published an account of his adventures in Wanderings of  an Artist (1859). Half of his paintings are portraits, works of great his�  torical value in which he recorded the dress and ornaments of his subjects  in accurate detail. He excelled at composing large figurative groups in a  style similar to contemporary European genre painting.</p><p>Kanem-Bornu Yka- I nem- , bor-nu\ Former African empire around Lake  Chad. It was ruled by the Sef dynasty in the 9th-19th century. Its terri�  tory at various times included what is now southern Chad, northern Cam�  eroon, northeastern Nigeria, eastern Niger, and southern Libya. Probably  founded in the mid-9th century, it became an Islamic state at the end of  the 11th century. Its location made it a trading hub between North Africa,  the Nile Valley, and the sub-Saharan region. From the 16th century  Kanem-Bornu, sometimes called simply Bornu, was extended and con�  solidated. The Sef dynasty died out in 1846.</p><p>Kang Vkaq-'yo-'waV Youwei or K'ang Yu-wei (b. March 19, 1858,  Guangdong province, China�d. March 31, 1927, Qingdao, Shandong)  Chinese scholar, a key figure in the intellectual development of modem  China. In 1895 Kang led hundreds of provincial graduates to protest the  humiliating terms of China�s treaty with Japan after the Sino-Japanese War  and to petition for reforms to strengthen the nation. In 1898 the Qing  emperor launched a reform program that included streamlining the gov�  ernment, strengthening the armed services, promoting local self-  government, and opening Beijing University. The empress Cixi annulled  the reforms and had six reform leaders executed, and Kang had to flee the  country. In exile, he opposed revolution; instead, he favoured rebuilding  China through science, technology, and industry. He returned in 1914 and  participated in an abortive restoration of the emperor. His fears of a  divided country led him to oppose the government of Sun Yat-sen in  southern China. Kang is also known for his reappraisal of Confucius,  whom he saw as a reformer.</p><p>kangaroo Most specifically, any of six large Australasian marsupials of  the family Macropodidae. The term  is also used to refer to any of the  family�s 54 species. Most kangaroos  graze on the Australian plains, but  tree kangaroos are arboreal; they  climb trees and leap from branch to  branch. Kangaroos generally have  long, powerful hind legs and feet and  a long tail, thickened at the base. The  hind legs enable their spectacular  leaps and are also useful for self-  defense; the tail is used for balance.</p><p>The head is small, the ears large and  rounded, and the fur soft and woolly.</p><p>Females have one young (called a  joey) annually; it is suckled in its  mother�s pouch for six months and  often returns to be carried in the  pouch later as well. The gray kanga�  roo, the best-known and second-  largest species, can leap more than  30 ft (9 m). The red kangaroo is the  largest species; the male may stand 6  ft (1.8 m) tall and weigh 200 lbs (90  kg). Millions are killed annually for  their meat and hides and because they compete with livestock for forage.  See also wallaby; wallaroo.</p><p>Kangaroo Island Island (pop., 1996: 4,118), South Australia. Located  at the entrance to the Gulf St. Vincent, southwest of Adelaide, Kangaroo  Island is 90 mi (145 km) long with an area of 1,680 sq mi (4,350 sq km).  Visited in 1802 by the English explorer Matthew Funders, it was named  for its many kangaroos.

May 4,</p><p>1654, Beijing, China�d. Dec. 20, 1722, Beijing) Second emperor of the  Qing dynasty. His personal name was Xuanye. One of China�s most  capable rulers, Kangxi (r. 1661-1722 ) laid the foundation for a long  period of political stability and prosperity. Under his reign, the Treaty of  Nerchinsk was signed with Russia, parts of Outer Mongolia were added  to China�s territory, and control was extended over Tibet. Domestically,  Kangxi�s reign was a time of large-scale public works, such as repairing  the Grand Canal to permit transportation of rice to feed the northern  population, and dredging and banking the Huang He (Yellow River) to  prevent destructive flooding. Kangxi reduced taxes many times and  opened four ports to foreign ships for trade. Though an ardent proponent  of Neo-Confucianism, he also welcomed Jesuit missionaries, whose  accomplishments led him to permit the propagation of Roman Catholi�  cism in China. He commissioned many books, including the Kangxi dic�  tionary and a history of the Ming dynasty.

He is thought to have taken the throne between ad 78 and 144 and  to have ruled for 23 years. Kaniska is noted for having convened a Bud�  dhist council that marked the beginnings of Mahayana Buddhism. He was  a tolerant king who honoured the Zoroastrian, Greek, and Brahmanic dei�  ties as well as Buddha. During his reign, trade with the Roman Empire  increased significantly, and contact between him and the Chinese in Cen�  tral Asia may have inspired the transmission of Buddhism to China.</p><p>Kannada Vka-no-doV language formerly Kanarese \,ka-n3-'rez\  language Dravidian language, the official language of the Indian state  of Karnataka.

The British acquired it in 1801  and made it one of their frontier stations. In 1857, during the Indian Mutiny,  it was the site of the massacre of British troops and civilians by native  forces. One of the largest cities in India, it is a hub of road and rail trans�  portation and a major commercial and industrial centre. Its educational  institutions include a university and the Indian Institute of Technology.</p><p>Kansas State (pop., 2000: 2,688,418), central U.S. Bordered by  Nebraska, Missouri, Oklahoma, and Colorado, it covers 82,282 sq mi  (213,110 sq km); its capital is Topeka. It is located on the Great Plains,  rising more than 3,000 ft (915 m) from its eastern prairies to the high  plains of the west. The region was occupied by the Kansa, Osage, Paw�  nee, and Wichita Indians before European settlement. The first European  explorer was Francisco Vazquez de Coronado, who came from Mexico  in 1541 in search of gold. La Salle claimed the region for France in 1682.  Kansas was acquired by the U.S. as part of the Louisiana Purchase in 1803.  In the early 19th century the federal government relocated displaced east�  ern Indians to Kansas. The Kansas-Nebraska Act of 1854 created the Kan�  sas Territory and opened it to white settlement. It was the site of conflicts  over slavery, including one spurred by John Brown (see Bleeding Kansas).  It entered the Union as the 34th state in 1861. After the Civil War, the  coming of the railroads promoted the growth of cow towns; Texas cattle�  men drove herds to Wichita and Abilene to reach the railheads. Agricul�  ture became important as farmers worked on the Great Plains. During and  following World War II, airplane production expanded, and farm products  remained strong.</p><p>Kansas, Bleeding See Bleeding Kansas</p><p>Kansas City City (pop., 2000: 441,545), western Missouri, U.S., on  the Missouri River. The city is contiguous with Kansas City, Kan. First  settled by French fur traders in 1821, it was known as Westport, prosper�  ing as a river port and as the terminus for the Santa Fe Trail and the Oregon  Trail. Chartered in 1850 as the town of Kansas and as a city in 1853, it  was renamed Kansas City in 1889 to distinguish it from the territory. The  state�s largest city, it is an important marketing and shipping centre for a  vast agricultural region and has extensive grain-storage and food�  processing facilities. It is the seat of the University of Missouri at Kan�  sas City and the world headquarters for the Church of the Nazarene.</p><p>Kansas-Nebraska Act (1854) Legislation that organized the terri�  tories of Kansas and Nebraska according to the doctrine of popular sov�  ereignty. Introduced by Sen. Stephen A. Douglas to stop the sectional  division over slavery, the act was criticized by antislavery groups as a  capitulation to proslavery advocates. Groups on both sides rushed to settle  Kansas Territory with their adherents, leading to the chaotic Bleeding Kan�  sas period. Passage of the act led to the formation of the Republican Party  as a political organization opposed to the expansion of slavery to any U.S.  territory.</p><p>Kansas River or Kaw River River, northeastern Kansas, U.S. It  flows east and empties into the Missouri River at Kansas City.

April 22, 1724, Konigsberg, Prussia�d.  Feb. 12, 1804, Konigsberg) German philosopher, one of the foremost  thinkers of the Enlightenment. The son of a saddler, he studied at the uni�  versity in Konigsberg and taught there as privatdocent (1755-70) and later  as professor of logic and metaphysics (1770-97). His life was unevent�  ful. His Critique of Pure Reason (1781) discusses the nature of knowl�  edge in mathematics and physics and demonstrates the impossibility of</p><p>knowledge in metaphysics as it was traditionally conceived. Kant argued  that the propositions of mathematics and physics, but not those of meta�  physics, are �synthetic a priori,� in the sense that they are about objects  of possible experience (synthetic) but at the same time knowable prior to,  or independently of, experience (a priori), thus making them also neces�  sarily true, rather than merely contingently true (see necessity). Mathemat�  ics is synthetic and a priori because it deals with space and time, both of  which are forms of human sensibility that condition whatever is appre�  hended through the senses. Similarly, physics is synthetic and a priori  because in its ordering of experience it uses concepts (�categories�) whose  function is to prescribe the general form that sensible experience must  take. Metaphysics in the traditional sense, understood as knowledge of  the existence of God, the freedom of the will, and the immortality of the  soul, is impossible, because these questions transcend any possible sense  experience. But though they cannot be objects of knowledge, they are  nevertheless justified as essential postulates of a moral life. Kant�s eth�  ics, which he expounded in the Critique of Practical Reason (1788) and  the earlier Groundwork of the Metaphysics of Morals (1785), was based  on the principle known as the �categorical imperative,� one formulation  of which is, �Act only on that maxim through which you can at the same  time will that it should become a universal law.� His last great work, The  Critique of Judgment (1790), concerns the nature of aesthetic judgment  and the existence of teleology, or purposiveness, in nature. Kant�s thought  represents a turning point in the history of philosophy. In his own words,  he effected a Copernican revolution: just as the founder of modern  astronomy, Nicolaus Copernicus, had explained the apparent movements  of the stars by ascribing them partly to the movement of the observers,  so Kant had accounted for the existence of a priori synthetic knowledge  by demonstrating that in knowing, it is not the mind that conforms to  things but instead things that conform to the mind.

Kantianism comprises diverse philosophies  that share Kant�s concern to explore the nature and limits of human  knowledge in the hope of raising philosophy to the level of a science.  Each submovement of Kantianism has tended to focus on its own selec�  tion and reading of Kant�s many concerns. In the 1790s there emerged in  Germany the so-called semi-Kantians, who altered features of Kant�s sys�  tem they viewed as inadequate, unclear, or even wrong; its members  included Friedrich Schiller, Friedrich Bouterwek (1766-1828), and Jakob  Friedrich Fries (1773-1843). The period from 1790 to 1835 was the age  of the post-Kantian idealists (see idealism). A major revival of interest in  Kantian philosophy began c. 1860. See also Johann Gottlieb Fichte; G.W.F.

Soviet math�  ematician and economist. A professor at Leningrad State University  (1934-60), he developed the linear prograaaming model as a tool of eco�  nomic planning. He used mathematical techniques to show how decen�  tralization of decision making in a planned economy ultimately depends  on a system in which prices are based on the relative scarcity of resources.  His nondogmatic critical analyses of Soviet economic policy often clashed  with the views of his orthodox Marxist colleagues. His most notable work  is The Best Use of Economic Resources (1959). In 1975 he and Tjalling  Koopmans (1910-85) shared the Nobel Prize for their work on optimal  allocation of scarce resources.</p><p>Kanuri \k9-'nur-e\ People of northeastern Nigeria and southeastern  Niger, with smaller numbers in Chad, Cameroon, and Sudan.

They were an offshoot of the Shaivites (see Shaivism),  who worshiped Shiva, and their notorious practices included human sac�  rifice. After sacrificing a Brahman or other high-ranking person, they  embraced a 12-year vow of self-abnegation that included eating and drink�  ing from the skull of the sacrificed person and following tantric practices  such as going about naked, eating the flesh of the dead, and smearing  themselves with the ashes of corpses.

Ordained at the  Jewish Theological Seminary, he later taught there for 50 years. In 1916  he organized the Jewish Center in New York as a secular community  organization with a synagogue as its nucleus. In 1922 he founded the  Society for the Advancement of Judaism, which became the core of  Reconstructionism. Denying the literal accuracy of the Bible, he called for  a new conception of God in an attempt to adapt Judaism to the modem  world. He founded the journal The Reconstructionist in 1935; his books  include Judaism as a Civilization (1934) and Judaism without Supersti�  tion (1958).</p><p>kapok \'ka-,pak\ Fibre obtained from the large, tropical silk cotton, or  kapok, tree ( Ceiba pentandra, family Bombacaceae), which bears hun�  dreds of seedpods filled with fibrous seeds. The tree is grown chiefly in  Asia and Indonesia. Sometimes called silk cotton or Java cotton, this  moisture-resistant, quick-drying, resilient, buoyant fibre has been used in  life preservers and other water-safety equipment. Kapok is also used to  stuff pillows, mattresses, and upholstery, as insulation, and as a cotton  substitute in surgery. However, it is highly flammable, and the fibres are  too brittle for spinning. Its importance has decreased with the develop�  ment of foam rubber, plastics, and man-made fibres.</p><p>Kapoor, Raj (b. Dec. 14, 1924, Peshawar, India�d.

In 1950 he  formed his own Bombay (now Mumbai) film studio, RK, and the next  year he achieved romantic stardom in Awara (1951; �The Vagabond�).  He wrote, produced, directed, and starred in many successful films.  Although he portrayed romantic leads in his early movies, his best-known  characters were based on Charlie Chaplin�s tramp. His use of sexual imag�  ery often challenged traditionally strict Indian film standards, and many  of his film songs became musical hits.</p><p>Kaposi \'ka-po-se\ sarcoma Usually lethal cancer appearing as red-  purple or blue-brown spots on the skin and other organs.

The accumulated  moral energy of a person�s life determines his or her character, class sta�  tus, and disposition in the next life. The process is automatic, and no  interference by the gods is possible. In the course of a chain of lives,  people can perfect themselves and reach the level of Brahma, or they can  degrade themselves to the extent that they return to life as animals.

Jews observing  kashruth may eat only fish with scales and fins and animals that chew the  cud and have cloven feet; shellfish and pork are thus forbidden. Animals  and birds must be slaughtered according to ritual and with prayer. Meat  and dairy products must be strictly separated; they may not be eaten at  the same meal or from the same set of dishes. No restrictions apply to the  use of fruits and vegetables.

The true katydids of eastern  North America are considered great  singers; each species has its own  repetitive song, which is produced  only at night.</p><p>Katyn \ka-'tin\ Massacre Mass killing of Polish military officers by  the Soviet Union in World War II. After the German-Soviet Nonaggres�  sion Pact (1939) and Germany�s defeat of Poland, Soviet forces occupied  eastern Poland and interned thousands of Polish military personnel. After  the German invasion of the Soviet Union (1941), the Polish government-  in-exile agreed to cooperate with the Soviets against Germany, and the  Polish general forming the new army asked to have the Polish prisoners  placed under his command, but the Soviet government informed him in  December 1941 that most of those prisoners had escaped to Manchuria  and could not be located. In 1943 the Germans discovered mass graves  in the Katyn forest in western Russia. A total of 4,443 corpses were  recovered; the victims had apparently been shot from behind and then  piled in stacks and buried. The Soviet government claimed the invading  German army had killed them, but it refused Polish requests to have the  Red Cross investigate. In 1992 the Russian government released docu�  ments proving that the Soviet secret police were responsible for the execu�  tions and cover-up.</p><p>Kauffmann \'kauf-,man\ / (Ma�  ria Anna) Angelica (Catha�  rine) (b.

After graduating from Princeton University in 1925, he entered the U.S.  foreign service, studied Russian language and culture at the University of  Berlin (1929-31), and was assigned to the U.S. embassy in Moscow  (1933-35). He served in Vienna, Prague, Berlin, and Lisbon, returning to  Moscow during and after World War II. His concept of containment was  presented in a highly influential article, signed �X,� that appeared in For�  eign Affairs magazine in July 1947. Kennan questioned the wisdom of  conciliatory U.S. policy toward the Soviet Union, which he considered  appeasement, and advocated instead U.S. counterpressure wherever the  Soviets threatened to expand; this approach became the basis of U.S.  policy toward the Soviet Union during the first decades of the Cold War.  After brief service as an adviser to the State Department, he joined the  Institute for Advanced Study at Princeton as professor of historical stud�  ies (1956-74); his tenure there was interrupted by a stint as U.S. ambas�  sador to Yugoslavia (1961-63).

A graduate of Harvard Law School, he practiced law in  San Francisco and Sacramento before being appointed to the U.S. Circuit  Court of Appeals in 1975. He was nominated to the U.S. Supreme Court  in 1988 by Pres. Ronald Reagan. His record generally reflected his con�  servative outlook, and he consistently voted against policies such as affir�  mative action and abortion rights. His episodic departure from conservative  jurisprudence stemmed from his civil libertarian perspective on certain  individual rights.</p><p>Kennedy, Edward M(oore) known as Ted Kennedy (b. Feb. 22,  1932, Brookline, Mass., U.S.) U.S. senator. He is the youngest son of  Joseph P. Kennedy and the brother of John F. Kennedy and Robert F. Kennedy.  He graduated from Harvard University in 1956 and received a law degree  from the University of Virginia in 1959. In 1962 he was elected to the  former U.S. Senate seat of his brother John, who became president in  1960. Elected Democratic majority whip in 1969, he was considered a  front-runner for the 1972 Democratic presidential nomination. In 1970 he  was involved in a car accident on Chappaquiddick Island, near Martha�s  Vineyard, Mass., in which a companion in his car was drowned. Kennedy</p><p>was found guilty of leaving the scene of an accident. Though he was  reelected to the Senate in 1970, he decided against seeking the presidency  in 1972. He won a third full term in 1976 and was again a serious con�  tender for the Democratic nomination in 1980, but he withdrew during  the convention. In subsequent years his presidential prospects were lim�  ited by memories of the Chappaquiddick incident and by his somewhat  raffish personal life. In the 1980s and �90s he continued to represent Mas�  sachusetts in the Senate, where he was a forceful spokesman for liberal  causes, including civil rights, consumer protection, and national health  insurance.</p><p>Kennedy, John F(itzgerald) (b. May 29, 1917, Brookline, Mass.,  U.S.�d. Nov. 22, 1963, Dallas,</p><p>Texas) 35th president of the U.S.</p><p>(1961-63). The son of Joseph P.</p><p>Kennedy, he graduated from Harvard  University in 1940 and joined the  navy the following year. He com�  manded a patrol torpedo (PT) boat in  World War II and was gravely  injured in an attack by a Japanese  destroyer; he was later decorated for  heroism. Elected to the U.S. House  of Representatives in 1946 and the  U.S. Senate in 1952, he supported  social-welfare legislation and  became increasingly committed to  civil rights; in foreign affairs, he sup�  ported the Cold War policies of the  Truman administration. In 1960 he  won the Democratic nomination for  president, beating out Lyndon B.</p><p>Johnson, who became his running mate. In his acceptance speech  Kennedy declared, �We stand on the edge of a New Frontier�; thereafter  the phrase �New Frontier� was associated with his programs. After a vig�  orous campaign managed by his brother Robert F. Kennedy and aided finan�  cially by his father, he narrowly defeated the Republican candidate,  Richard Nixon. He was the youngest person and the first Roman Catholic  elected president. In his inaugural address he called on Americans to �ask  not what your country can do for you, ask what you can do for your coun�  try.� His legislative program, including massive income-tax cuts and a  sweeping civil-rights measure, received little support in the Congress,  though he did win approval of the Peace Corps and the Alliance for  Progress. In 1961 he committed the U.S. to land a man on the Moon by  the end of the decade. In foreign affairs he approved a plan drawn up  during the Eisenhower administration to land an invasion force of Cuban  exiles on their homeland, but the Bay of Pigs invasion (1961) was a fiasco.  Determined to combat the spread of communism in Asia, he sent military  advisers and other assistance to South Vietnam. During the Cuban missile  crisis (1962) he imposed a naval blockade on Cuba and demanded that the  Soviet Union remove its nuclear missiles from the island. In 1963 he suc�  cessfully concluded the Nuclear Test-Ban Treaty with Britain and the Soviet  Union. In November 1963, while riding in a motorcade in Dallas, he was  assassinated by a sniper, allegedly Lee Harvey Oswald. The killing is con�  sidered the most notorious political murder of the 20th century. Kennedy�s  youth, energy, and charming family brought him world adulation and  sparked the idealism of a generation, for whom the Kennedy White House  became known as �Camelot.� Revelations about his powerful family and  his personal life, especially concerning his extramarital affairs, tainted his  image in later years.

He graduated from Harvard University in 1912. He was a bank  president by age 25 and a millionaire at age 30. He became a shipbuilder,  a motion-picture tycoon, and a large contributor to the Democratic Party.  During the 1920s he acquired a large fortune by speculating in the stock  market; he is also alleged to have traded in bootleg liquor during Prohi�  bition. Later, as chairman of the Securities and Exchange Commission  (1934-35), he outlawed the speculative practices, including insider trad�  ing and stock manipulation, that had made him rich.

He man�  aged the U.S. Senate campaign of his brother John F. Kennedy in 1952. In  1957 he became chief counsel to the Senate committee investigating  labour racketeering; he resigned the post in 1960 to manage his brother�s  presidential campaign. As U.S. attorney general (1961�64), he led a drive  against organized crime that resulted in the conviction of labour leader  Jimmy Hoffa. In 1964 he was elected to the U.S. Senate from New York.  He became a spokesman for liberal Democrats and a critic of the Viet�  nam policy of Lyndon B. Johnson.

Among its geographical  features are the Appalachian Mountains of the east, the interior lowlands,  including the Bluegrass region, and the rich lowlands along the Mississippi  River. Before the arrival of white settlers, the region was a hunting ground  for Indian tribes, including the Shawnee, Iroquois, and Cherokee. Daniel  Boone, among the first white settlers, arrived in 1769; a wave of immi�  gration followed the American Revolution. Settlements began as part of a  district of Virginia, but in 1792 Kentucky entered the Union as the 15th  state. It was a border state during the American Civil War, remaining in  the Union but providing troops to both sides. The opening of rail lines  into the eastern coal country and the introduction of a tobacco economy  spurred growth in the late 19th century. In the 1970s a nationwide energy  shortage created a demand for coal, from which Kentucky prospered, but  demand dropped in the 1980s and many jobs were lost. Manufacturing is  the leading source of income, while tobacco is the chief crop.

Area:  224,961 sq mi (582,646 sq km). Population (2005 est.): 33,830,000. Capi�  tal: Nairobi. With a small group of European settlers� descendants, there  are dozens of ethnic groups, including the Kikuyu, Luhya, Luo, Kamba,  Kalenjin, and Masai. Languages: Swahili, English (both official), Kikuyu,  Luhya, Luo, others. Religions: Christianity (Roman Catholic, Protestant,  other Christians); also traditional beliefs, Islam. Currency: Kenya shilling.  Kenya can be divided into five regions: the Lake Victoria basin in the  southwest; the vast plateau of eastern Kenya; the 250-mi- (400-km-) long  coastal belt along the Indian Ocean; the highlands of the Mau Escarpment  on the western side of the Great Rift Valley in western Kenya; and the  highlands and mountains of the Aberdare Range on the eastern side of the  Rift Valley, including Mount Kenya. It is noted for such wildlife as lions,  leopards, elephants, buffalo, rhinoceroses, zebras, hippopotamuses, and  crocodiles. About one-tenth of the land is arable, and more than one-third  is used for grazing cattle, goats, and sheep. Agriculture employs much of  the workforce, and tea and coffee are the leading exports. Kenya is a  republic with one legislative house; its head of state and government is  the president. The coastal region was dominated by Arabs until it was  seized by the Portuguese in the 16th century. The Masai people held sway  in the north and moved into central Kenya in the 18th century, while the  Kikuyu expanded from their home region in south-central Kenya. The  interior was explored by European missionaries in the 19th century. After  the British took control, Kenya was established as a British protectorate  (1895) and a crown colony (1920).

Of Kikuyu  descent, Kenyatta left the East Afri�  can highlands c. 1920 to become a  civil servant and political activist in  Nairobi. He opposed a union of the  British colonial territories of Kenya,</p><p>Uganda, and Tanganyika. In 1945 he  helped organize the sixth Pan-  African Congress, attended by such  figures as W.E.B. Du Bois and Kwame  Nkrumah (see Pan-African move�  ment). In 1953 he was sentenced to a  seven-year prison term for directing  the Mau Mau rebellion, though he  denied the charges. In 1962 he nego�  tiated the constitutional terms lead�  ing to Kenya�s independence. As its  leader he headed a strong central  government, rejected calls to nation�  alize property, and made Kenya one  of the most stable and economically  dynamic African states. Critics com�  plained of the dominance of his Kenya African National Union (KANU)  party and the creation of a political and economic elite.

Many Indians, witnessing the showering of gifts and honours on  Keokuk by U.S. Indian agents and military leaders, turned to him for  leadership. In 1832 Black Hawk led a short-lived resistance effort against  white encroachments; Keokuk counseled peace and surrender, and he  even provided advance warning to the U.S. of Black Hawk�s intentions.  For this assistance, the U.S. government named Keokuk leader of the Sauk  nation in 1837. Keokuk responded by ceding the Illinois lands of his tribe  and moving his people to Iowa. He continued to give away tribal land  until his people were forced to settle on a reservation in Kansas, where  he died in disgrace, despite the wealth and power he had accumulated.</p><p>Kepler, Johannes (b.

He received  an M.A. in 1594, after which he became a mathematics teacher in Aus�  tria. He developed a mystical theory that the cosmos was constructed of  the five regular polyhedrons, enclosed in a sphere, with a planet between  each pair. He sent his paper on the subject to Tycho Brahe, who invited  Kepler to join his research staff. In attempting to understand atmospheric  refraction of light, he became the first to explain accurately how light  behaves within the eye, how eyeglasses improve vision, and what hap�  pens to light in a telescope. In 1609 he published his finding that the orbit  of Mars was an ellipse and not the perfect circle hitherto presumed to be  the orbit of every celestial body. This fact became the basis of the first of  Kepler�s three laws of planetary motion. He also determined that planets  move faster as they near the Sun (second law), and in 1619 he showed  that a simple mathematical formula related the planets� orbital periods to  their distance from the Sun (third law). In 1620 he defended his mother  from charges of witchcraft, thereby preserving his own reputation as well.</p><p>Kerala \'ker-3-b\ State (pop., 2001 prelim.: 31,838,619), southwestern  India.

At Columbia  he met Allen Ginsberg and other kindred spirits, and he became a spokes�  man of what would be dubbed the Beat movement (a term he coined). He  celebrated its code of poverty and freedom in On the Road (1957); his best-  known novel, and the first written in the nonstop, unedited style that he  advocated, it enjoyed a huge success among young people, for whom Ker�  ouac became a romantic hero. All his novels, including The Dharma Bums  (1958), The Subterraneans (1958), and Desolation Angels (1965), are auto�  biographical. His death at age 47 resulted from alcoholism.</p><p>Kerr Vkar, 'kor\, Deborah orig. Deborah Jane Kerr-Trimmer</p><p>(b. Sept. 30, 1921, Helensburgh, Dunbartonshire, Scot.) Scottish actress.  After performing in British films such as Major Barbara (1940) and Black  Narcissus (1947), she moved to Hollywood, where she was often cast in  prim roles, though her part in From Here to Eternity (1953) was a depar�  ture from her ladylike image. Known for the poise and serenity she exhib�  ited in portraying complex characters, she appeared in later films  including The King and I (1956), Tea and Sympathy (1956), Heaven</p><p>Knows, Mr. Allison (1957), Separate Tables (1958), The Sundowners  (1960), and The Night of the Iguana (1964). She retired from the screen  in 1969. She received a special Academy Award in 1994.</p><p>13th century, Java) Last king</p><p>Kertanagara X.ker-to-'na-go-roN (fl  (1268-92) of Tumapel (Singhasari)  in Java. His birth reunited the two  halves of the Javanese kingdom, and  his name means �Order in the  Realm.� To bolster his kingdom  against Kublai Khan, he expanded it,  marrying a princess of Champa (cen�  tral Vietnam), sending envoys to  Malayu (Sumatra), and conquering  Bali. He refused to pay homage to  Kublai Khan but was killed by a vas�  sal before Kublai�s armed forces  arrived to punish him. Two early Jav�  anese chronicles give contradictory  pictures of the king: one describes  him as drunken and incompetent; the  other depicts him as a wise king and  zealous follower of Tantric Bud�  dhism. He is still venerated as one of  Java�s greatest rulers.</p><p>Kertesz \ker-'tesh\, Andre (b.</p><p>July 2, 1894, Budapest, Austro-  Hungarian Empire�d. Sept. 27,</p><p>1985, New York, N.Y., U.S.)</p><p>Hungarian-born U.S. photographer  and photojournalist. He moved from  Budapest to Paris in 1925 in search  of opportunity and became a major  contributor to European illustrated  periodicals. He became friendly with  many influential artists, including  Marc Chagall and Piet Mondrian; his  access to such figures allowed him to  create a definitive portrait of the  Parisian cultural milieu of the period.</p><p>In 1928 he bought a Leica, a small</p><p>handheld camera. The lightweight camera gave him the freedom to move  about the streets of Paris and capture spontaneous moments of urban life,  a subject that would fascinate him throughout his career. He arrived in  New York City in 1936 intending to work for a commercial studio for a  year, but stayed on, doing largely fashion photography for major U.S.  magazines. He returned to his pursuit of urban life c. 1962, and in 1964 the  Museum of Modem Art gave an exhibition of his works. His spontaneous,  unposed pictures exerted a strong influence on magazine photography.</p><p>Stone sculpture thought to be Kertana�  gara in the form of hari-hara ardha-  nari, c. early 14th century; acquired by  the Museum fur Volker Kunde, Berlin,  in 1865.</p><p>ENCYCLOPEDIA BRITANNICA, INC.</p><p>kerygma and catechesis Vko-'rig-mo, , kir-ig-m3...,ka-t3- , ke-s3s\ In  Christian theology, literally, preaching and teaching. Kerygma means the  proclamation of the Gospel, especially by the Apostles as recorded in the  New Testament. In the early church, catechesis referred to the oral instruc�  tion (geared to the general absence of literacy) given before baptism to  those who had accepted the message of salvation. As the practice of infant  baptism spread, a shift took place to teaching the already baptized in  preparation for full adult membership, and churches developed statements  of basic doctrine called catechisms.</p><p>Kesey Vke-ze\, Ken (Elton) (b. Sept. 17, 1935, La Junta, Colo.,  U.S.�d. Nov. 10, 2001, Eugene, Ore.) U.S. writer. He attended Stanford  University and later served as an experimental subject and aide in a hos�  pital, an experience that led to his novel One Flew over the Cuckoo�s Nest  (1962; film, 1975), which in the U.S. became one of the most widely read  books of the 1960s. It was followed by Sometimes a Great Notion (1964)  and several works of nonfiction that detailed Kesey�s transformation from  novelist to guru of the hippie generation. They recount psychedelic, fancy-  free travels on a brightly painted bus with a group of friends, relatives,  and fans who called themselves the Merry Pranksters. Their story is  recounted in Tom Wolfe�s Electric Kool-Aid Acid Test (1968), itself a  minor classic of the era.</p><p>Kesselring, Albert (b. Nov. 20, 1885, Marktstedt, Bavaria, Ger.�d.

In 1941 he was appointed  commander in chief, south, to bolster Italy�s efforts in North Africa and  against Malta. He codirected the Axis campaign in North Africa with  Erwin Rommel. After the Allied invasions of Sicily and Italy in 1943, he  fought an effective defensive action that prevented an Allied victory in  that theatre until 1944. Appointed commander in chief, west, in 1945, he  was unable to stop the Allies� drive into Germany and surrendered the  southern half of the German forces in May 1945. He was imprisoned for  war crimes (1947-52).</p><p>kestrel Vkes-troA Any of several birds of prey (genus Falco) known for  hovering while hunting. Kestrels  prey on large insects, birds, and  small mammals. The male is more  colourful than the female. Kestrels  are mainly Old World birds, but one  species, the American kestrel ( F.  sparverius), often called the sparrow  hawk in the U.S., is common  throughout North and South  America. It is about 12 in. (30 cm)  long, white or yellowish below, and  reddish brown and slate-gray above  with colourful markings on the head.</p><p>The common kestrel ( F. tinnunculus )  of the Old World is larger and less  colourful.

Ketones can participate in many chemical reactions, though to a  lesser extent than the related aldehydes. Many more complex organic com�  pounds have ketones as building blocks. Their chief industrial use is as  solvents and in the manufacture of explosives, lacquers, paints, and tex�  tiles. Acetone is the most important ketone; several sugars and some natu�  ral and synthetic steroids are ketones. In ketosis, ketones produced by lipid  metabolism accumulate in the blood and urine in abnormal amounts, usu�  ally because of starvation or a metabolic disease such as diabetes mellitus.</p><p>Kettering, Charles F(ranklin) (b. Aug. 29, 1876, Loudonville,  Ohio, U.S.�d. Nov. 25, 1958, Dayton, Ohio) U.S. engineer. In 1904 he  developed the first electric cash register. With Edward Deeds he founded  Delco c.. 1910; in 1916 Delco became a subsidiary of General Motors  Corp., and Kettering served as vice president and director of research for  GM (1920-47). Many of his inventions were instrumental in the evolu�  tion of the modem automobile, including the first electric starter (1912),  antiknock fuels, leaded gasoline, quick-drying lacquer finishes (with Tho�  mas Midgley, Jr.), the high-speed, two-cycle diesel engine, and a revolu�  tionary high-compression engine (1951).

Kevlar can be made  into strong, tough, stiff, high-melting fibres, five times stronger per weight  than steel; it is used in radial tires, heat- or flame-resistant fabrics, bul�  letproof clothing, and fibre-reinforced composite materials for aircraft  panels, boat hulls, golf-club shafts, and lightweight bicycles.</p><p>Kevorkian, Jack (b. May 26, 1928, Pontiac, Mich., U.S.) U.S.  pathologist, advocate and practitioner of physician-assisted suicide. He  expressed early interest in experimentation on death-row inmates who had  been rendered unconscious rather than executed; his ideas negatively  affected his medical career. In the 1980s he devised his �suicide machine,�  with which a person could commit suicide by merely pushing a button,  and in the 1990s he assisted in the deaths of over 100 terminally ill per�  sons. His actions provoked furious controversy and led to legislation and  referenda; he was tried, convicted twice, and jailed, and his medical  license was revoked. In 1998 he was convicted of murder for adminis�  tering a lethal injection himself and was sentenced to 10-25 years in jail.</p><p>Kew Gardens officially Royal Botanic Gardens, Kew Botanic  garden located at Kew, site of a former royal estate in the London bor�  ough of Richmond upon Thames. In 1759 Augusta, dowager princess of  Wales and mother of George III, laid out a portion of her estate as a botanic  garden. It became an eminent scientific institution under the unofficial  directorship of Joseph Banks. In 1840 the gardens were donated to the  nation. Under Sir William Jackson Hooker (1785-1865), they became the  world�s leading botanical institution. Today they are home to 50,000 dif�  ferent types of plants, a herbarium of more than 5 million dried specimens,  and a library of more than 130,000 volumes. The three museums at Kew  are devoted largely to economic plant products and a laboratory of plant  genetics and classification.</p><p>key In music, system of PiTCHes and harmonies generated from a scale of  seven tones, one of which is predominantly important. Keys are a basic  element of tonality and represent an outgrowth of modal music (see church  mode). When a given piece is �in C,� C is its �tonic,� or central tone. Most  Western music after c. 1600 is written in either a major or a minor key.  The major scale consists of the interval pattern tone-tone-semitone-tone-  tone-tone-semitone. The minor scale consistently differs from it by begin�  ning with the pattern tone-semitone-tone, producing a minor third rather  than a major third above the tonic.</p><p>key, cryptographic Secret value used by a computer together with a  complex algorithm to encrypt and decrypt messages. Since confidential  messages might be intercepted during transmission or travel over public  networks, they require encryption so that they will be meaningless to third  parties in order to maintain confidentiality. The intended recipient, and  only the recipient, must also be able to decrypt them. If someone encrypts  a message with a key, only someone else with a matching key should be  able to decrypt the message. See also data encryption.</p><p>Key, David M(cKendree) (b. Jan. 27, 1824, Greene county, Tenn.,  U.S.�d. Feb. 3, 1900, Chattanooga, Tenn.) U.S. politician. Admitted to  the bar in 1850, he practiced law in Chattanooga and became active in  Democratic Party politics. He opposed secession by the South but served  in the Confederate army during the American Civil War, rising to the rank  of lieutenant colonel. After the war he worked to heal sectional griev�  ances and restore the Union. He was appointed to the U.S. Senate (1875),  succeeding former president Andrew Johnson, but two years later was  defeated in a bid to retain the seat. When the disputed 1876 presidential  election was turned over to a special Electoral Commission, the Republi�  can candidate, Rutherford B. Hayes, secured the support of Southern  Democrats by promising, among other things, to appoint a Southerner to  his cabinet. Key was thus appointed postmaster general in 1877. From  1880 to 1894 Key was a U.S. district judge in Tennessee.</p><p>Key, Francis Scott (b. Aug. 1, 1779, Frederick county, Md., U.S.�d.  Jan. 11, 1843, Baltimore, Md.) U.S. lawyer, author of �The Star Spangled  Banner.� After the burning of Washington, D.C., in the War of 181 2 he  was sent to secure the release of a friend from a British ship in Chesa�  peake Bay. He watched the British shelling of Fort McHenry during the  night of Sept. 13-14, 1814; when he saw the U.S. flag still flying the next  morning, he wrote the poem �Defense of Fort M�Henry.� Published in the  Baltimore Patriot, it was later set to the tune of an English drinking song,  �To Anacreon in Heaven.� The song was adopted as the U.S. national  anthem in 1931.</p><p>Key West City (pop., 2000: 25,478), southwestern Florida, U.S. The  southernmost city of the continental U.S., it lies on an island about 4 mi  (6.5 km) long and 1.5 mi (2.4 km) wide in the western Florida Keys. The  name is an English corruption of Cayo Hueso (�Bone Islet�), as it was  called by Spanish explorers who found human bones there. In 1822 a U.S.  naval depot was set up on Key West as a base of operations against pirates.  Now a winter resort, Key West is also a tourist destination.

It  refuted laissez-faire economic theo�  ries, arguing that the treatment for  economic depression was either to  enlarge private investment or to cre�  ate public substitutes for private  investment. Keynes argued that in  mild economic downturns, monetary  policy in the form of easier credit and  lower interest rates might stimulate  investment. More severe crises called  for deliberate public deficits (see defi�  cit financing), either in the shape of  public works or subsidies to the poor  and unemployed. Keynes�s theories  were put into practice by many West�  ern democracies, notably by the U.S. in the New Deal. Interested in the  design of new international financial institutions at the end of World War II,  Keynes was active at the Bretton Woods Conference in 1944.</p><p>John Maynard Keynes, detail of a  watercolour by Gwen Raverat, about  1908; in the National Portrait Gallery,  London.</p><p>Kgalagadi Transfrontier Park Nature conservation area in the  Kalahari Desert.

Its wildlife includes gemsboks, gnu (wilde�  beests), springbok, lions, jackals, and ostriches. It was officially estab�  lished in 2000 by merging Kalahari Gemsbok National Park in South  Africa with Gemsbok National Park in Botswana.

It was the descendant of  earlier agencies. The Cheka was established in 1917 to investigate coun�  terrevolution and sabotage. Its successor, the GPU (later OGPU), was the  new Soviet Union�s first secret-police agency (1923); it also administered  corrective labor camps and oversaw the forcible collectivization of Rus�  sia�s farms. By 1931 it had its own army and its spies and informers were  ubiquitous. In 1934 it was absorbed into the NKVD, which carried out  extensive purges. In 1941 the state-security and espionage functions were  combined in the MGB. In 1954 the KGB was created. At its peak, it was  the world�s largest secret-police and espionage organization. It lost power  under Mikhail Gorbachev, especially after leading a failed coup d�etat  (1991). It was renamed after the dissolution of the Soviet Union, and its  internal-security functions were segregated from its espionage and coun�  terespionage operations.</p><p>Khabur Vka-,bur\ River Turkish Habur River, southeastern Turkey  and northeastern Syria.

He gained international  notice when Sergey Prokofiev recommended one of his pieces for a Paris  concert. Active in the composer�s union, Khachaturian (along with Dmitry  Shostakovich and Prokofiev) was criticized by the government in 1948 for  �formalist tendencies,� though his music was in fact always conservative  and accessible. After Joseph Stalin�s death (1953), Khachaturian published  a call for greater artistic freedom. His ballet scores include Masquerade  (1944) and Spartacus (1954); Gayane (1943) contains the well-known  �Sabre Dance.� Other popular pieces include his piano and violin con�  certos.</p><p>Khadafy, Muammar al- See Muammar al-QADDAFi  Khafaje See Tutub  Khalil, Al- See Hebron  Khalkis See Chalkis</p><p>Khama III (b. c. 1837, Mushu, Bechuanaland�d.

They later caused further disruptions for the Umayyad  caliphs. Their constant attacks on Muslim governments were based on  their belief that the caliph should be chosen by the entire Muslim com�  munity.

By questioning him, Musa forfeits his patronage. Arab com�  mentators embellished the story, giving him the name Khidr (�Green�)  and claiming that he turned green upon diving into the spring of life.

Khnum  also had an important cult at Esna, south of Thebes.</p><p>Khoekhoe \ , koi-,koi\ or Khoikhoi formerly Hottentot (pejora�  tive) Group of peoples, speaking closely related Khoisan languages, who  were among the first indigenous southern Africans encountered by Euro�  peans. The precontact Khoekhoe were pastoralists who tended large herds  of cattle and sheep. By 1800 Khoekhoe societies south of the Orange  River in Cape Colony had been largely destroyed by disease and warfare,  with the remnants either serving as bonded labourers for white farmers  or blending into frontier communities of mixed descent, such as the Gri-  qua. North of the Orange River in Namibia, the Nama are the largest  Khoekhoe ethnic group, numbering about 230,000.</p><p>Khoisan Vkoi-.sanX languages Group of more than 20 languages  presently spoken by perhaps several hundred thousand Khoekhoe and San  peoples of southern Africa. A number of Khoisan languages are now either  extinct or spoken by very few people. Their most distinctive linguistic  characteristic is the original and extensive use of click consonants. The  genetic unity of the Khoisan languages remains disputed.</p><p>Khomeini \ko-'ma-ne\, Ruhollah orig. Ruhollah Musavi (b. May</p><p>17, 1900?, Khomeyn, Iran�d. June 3, 1989, Tehran) Shfite cleric and  leader of Iran (1979-89). He received a traditional religious education and  settled in Qom c. 1922, where he became a Shfite scholar of some repute  and an outspoken opponent first of Iran�s ruler, Reza Shah Pahlavi (r. 1926�  41), and then of his son, Mohammad Reza Shah Pahlavi (r. 1941-79). Popu�  larly recognized as a grand ayatollah in the early 1960s, he was  imprisoned and then exiled (1964) for his criticism of the government. He  settled first in Iraq�where he taught at the shrine city of Al-Najaf for  some years�and then, in 1978, near Paris, where he continued to speak  out against the shah. During that time he also refined his theory of  velayat-e faqih (�government of the jurist�), in which the Shfite clergy�  traditionally politically quiescent in Iran�would govern the state. Iranian  unrest increased until the shah fled in 1979; Khomeini returned shortly  thereafter and was eventually named Iran�s political and religious leader  (rcihbar). He ruled over a system in which the clergy dominated the gov�  ernment, and his foreign policies were both anti-Western and anticom�  munist. During the first year of his leadership, Iranian militants seized the  U.S. embassy in Tehran�greatly exacerbating tensions with the U.S.�  and the devastating Iran-Iraq War (1980-90) began.</p><p>Khons \'kons\ or Khensu \'ken-su\ or Chons \'kons\ Ancient Egyp�  tian moon god. He was the son of the god Amon and the goddess Mut.  He was usually depicted as a young man wearing a lunar disk and a rear�  ing cobra on his head. He was also associated with baboons and was  sometimes equated with Thoth, another moon god. In the late New King�  dom (c. 1100 bc) a major temple was built for Khons in the Karnak com�  plex at Thebes.</p><p>Khorana Xko-'ra-noV Har Gobind (b. Jan. 9, 1922, Raipur, India)  Indian-born U.S. biochemist. He received his Ph.D. from the University  of Liverpool and later taught in Canada and the U.S., from 1970 at MIT.  He shared a 1968 Nobel Prize with Marshall Warren Nirenberg and Rob�  ert William Holley for research that helped show how the genetic compo�  nents of the cell nucleus control the synthesis of proteins. His contribution  was to synthesize small nucleic acid molecules whose exact structure was  known. Combined with the proper materials, his synthetic nucleic acids  caused protein synthesis, just as in the cell; comparing these proteins with  the nucleic acid showed which portions of the nucleic acid were the codes  for each part of the protein. In 1970 he prepared the first artificial copy  of a yeast gene.</p><p>Khorasan \,k6r-a-'san\ or Khurasan \,kur-a-'san\ Province (pop.,  1996: 6,048,000), northeastern Iran. Its capital is Mashhad.

Under Arab  rule, it encompassed a vast territory including what is now southern Turk�  menistan and northern Afghanistan. It was conquered c. 1220 by Genghis  Khan and c. 1380 by Timur. Its current frontiers, as a province of Iran,  were defined in 1881. Its population is composed of many ethnic groups  as a result of numerous migrations and invasions over the centuries. The  languages spoken are Turkish, Persian, and Kurdish. The province gives  its name to the handcrafted Khorasan carpet.</p><p>Khorram-dman \k6r-,ram-de-'nan\ or Khorramiyyeh</p><p>\k6r-,ra-me-'yeh\ Islamic sect that flourished in the 9th-11th centuries.  Though they were Muslims, some members of this sect believed in trans�  migration of souls and in the Zoroastrian dualism of good and evil deities.  Like the ShT'ites, they were partisans of c Au in the succession of the caliph�  ate, and they held that Islam should be led by descendants of Muhammad.  They differed from the Shfites in insisting that the leadership should be  hereditary in the person of AbO Muslim. Claiming to be a descendant of  Abu, their leader Babak led a rebellion against the Abbasid Caliphate of  Baghdad, which ended with his capture and execution in 838. The sect  died out in the 11th century.</p><p>Khosrow \kos-'rau\ I or Khosrow AnushTrvan (d. 579) Persian  king (r. 531-579) of the Sasanian dynasty. He reformed taxation, reorga�  nized the army, and launched military campaigns against the Hephthalites  (a Central Asian people) and in Armenia, the Caucasus, and Yemen. He  is said to have had Sanskrit texts imported for translation. Under his reign,  chess was introduced from India, and astronomy, astrology, medicine, and  philosophy flourished. The Avesta was purportedly codified under his  reign, and in later eras his name became legend. Almost any pre-Islamic  structure in Iran whose origin is unknown is credited to him.</p><p>Khosrow II or Khosrow ParvTz (d. 628) King of the Sasanian  dynasty (r. 590-628) whose military exploits extended the empire to its  furthest extent. He came to the throne�assisted by Maurice, the emperor  of the Byzantine Empire �in troubled times. When a new Byzantine emperor  took the throne, however, Khosrow launched a war against the empire,  seizing Armenia and central Anatolia. In 613 his forces took Damascus,  and Jerusalem fell in 614. His fortunes suffered a reverse when Byzan�  tine forces recaptured lost ground and killed his ablest generals. Revolu�  tion within the royal family followed, and Khosrow was executed. Under  his reign, silverwork and carpet weaving reached a peak, and there is evi�  dence of a renaissance in rock sculpture. After his death the empire rap�  idly declined, falling to the Arabs during the Islamic conquests in 640.</p><p>Khrushchev \krush-'chof,\ English \'krush-chef\, Nikita  (Sergeyevich) (b.

In 1934 he was  elected to its Central Committee, and  in 1935 he became first secretary of  the Moscow party organization. He  participated in Joseph Stalin�s purges  of party leaders. In 1938 he became  head of the Ukrainian party and in  1939 was made a member of the  Politburo. After Stalin�s death in  1953, he emerged from a bitter  power struggle as the party�s first  secretary, and Nikolay Bulganin  became premier. In 1955, on his first  trip outside the Soviet Union,</p><p>Khrushchev showed his flexibility  and the brash, extraverted style of  diplomacy that would become his  trademark. At the party�s Twentieth  Congress in 1956, he delivered a secret speech denouncing Stalin for his  �intolerance, his brutality, his abuse of power.� Thousands of political  prisoners were released. Poland and Hungary used de-Stalinization to  reform their regimes; Khrushchev allowed the Poles relative freedom, but  he crushed the Hungarian Revolution by force (1956) when Imre Nagy  attempted to withdraw from the Warsaw Pact. Opposition within the party  crystallized in 1957, but Khrushchev secured the dismissal of his enemies</p><p>and in 1958 assumed the premiership himself. Asserting a doctrine of  peaceful coexistence with capitalist nations, he toured the U.S. in 1959,  but a planned Paris summit with Pres. Dwight D. Eisenhower in 1960 was  canceled after the U-2 Affair. In 1962 he attempted to place Soviet mis�  siles in Cuba; in the ensuing Cuban missile crisis, he retreated. Ideological  differences and the signing of the Nuclear Test-Ban Treaty (1963) led to a  split with the Chinese. Agricultural failures that necessitated importation  of wheat from the West, the China quarrel, and his often arbitrary admin�  istrative methods led to his forced retirement in 1964.</p><p>Khuddaka Nikaya Vku-do-ko-'ne-ko-yoX (Pali: �Short Collection�)  Collection of Buddhist texts.

He himself turned pirate on the voyage, took sev�  eral ships, and mortally wounded his gunner, William Moore. He surren�  dered in New York in 1699, having been promised a pardon. Sent to  England for trial, he was found guilty of Moore�s murder and five piracy  counts, and he was hanged. Some of his treasure was recovered from  Gardiners Island (off Long Island), but much has apparently never been  found.

Kidder  received his Ph.D. from Harvard University (1914) for developing the first  effective pottery typology relating to the prehistory of the southwestern  U.S. He later extended these interests to a classic study (1924) of the  development of the Pueblo cultures and to the creation (1927) of a widely  used archaeological classification system (the Pecos system) for the  Southwest. In 1929 he also organized an interdisciplinary program that  resulted in a far-reaching survey of cultural history in the Old and New  Maya empires of Mexico and Central America. He taught at Phillips  (Andover) Academy (1915-35) and at Harvard University (1939-50) and  oversaw various programs at the Carnegie Institution (1927-50).

In the second of the  Moroccan crises (1911), he refused conciliatory offers by the French gov�  ernment and excluded Britain from negotiations. Although German  expansionists denounced the peace treaty as too lenient, Kiderlen�s  brusque and forceful posturing during the crisis significantly aggravated  the international tensions that led to World War I.</p><p>kidnapping Crime of seizing, confining, abducting, or carrying away  a person by force or fraud, often to subject him or her to involuntary ser�  vitude, in an attempt to demand a ransom, or in furtherance of another  crime. Most countries consider it a grave offense punishable by a long  prison sentence or death.</p><p>kidney One of a pair of organs that maintain water balance and expel  metabolic wastes. Human kidneys are bean-shaped organs about 4 in. (10  cm) long, in the small of the back. They filter the entire 5-quart (about  4.5-liter) water content of the blood every 45 minutes. Glucose, miner�  als, and needed water are returned to the blood by reabsorption. The  remaining fluid and wastes pass into collecting ducts, flowing to the ure�  ter and bladder as urine. Each kidney has over 1 million functional units  (nephrons) involved in the process of filtration and reabsorption. The kid�  neys also secrete renin, an enzyme involved in blood pressure regulation.  Disorders include kidney failure, kidney stones, and nephritis. See also uri�  nary system. See illustration on following page.</p><p>kidney failure or renal failure Partial or complete loss of kidney  function. Acute failure causes reduced urine output and blood chemical  imbalance, including uremia. Most patients recover within six weeks. Dam�  age to various kidney structures can result from chemical exposure, major  blood loss, crush injury, hypertension, severe burns, severe kidney infections,  diabetes mellitus, renal artery or urinary tract blockage, and liver diseases.  Complications include heart failure, pulmonary edema, and high potassium  levels. Chronic failure usually results from long-term kidney diseases. The  blood becomes too acidic, bones can lose calcium, and nerves can degen�  erate. The kidneys can sustain life until they lose about 90% of their func�  tion. If one is removed, the other increases in size and function to  compensate. Failure of both usually requires dialysis or kidney transplant.</p><p>kidney stone or renal calculus Mass of minerals and organic mat�  ter that may form in a kidney. Urine contains many salts in solution, and  low fluid volume or high mineral concentration can cause these salts to  precipitate and grow, forming stones. Large stones can block urine flow,  be a focus for infection, or cause renal colic (painful spasms). They can  obstruct the urinary system at various points. Treatment deals with any  underlying problem (e.g., infection or obstruction), tries to dissolve stones  with drugs or ultrasound (lithotripsy), or removes large ones surgically.</p><p>kidney transplant or renal transplant Replacement of a diseased  or damaged kidney with one from a living relative or a legally dead donor.  The former�s tissue type is more likely to match, reducing the chance of  rejection; but removal puts the donor at risk, and a kidney from a dead  donor is more likely to be available. The new kidney is implanted and its  blood vessels and ureter sewn in place. A near-normal life may be resumed  within two months, but the drugs that prevent rejection leave the patient  vulnerable to infection.

Located in the middle of the country, it was a trading centre during the  German colonial administration (after 1895) and a regional centre during  the Belgian colonial period (1919-62). It became the capital of indepen�  dent Rwanda in 1962. The fast-growing city was adversely affected by  the country�s political turmoil in the 1990s.</p><p>Kikuyu \ki-'ku-yu\ or Gikuyu Bantu-speaking people who live in the  highland area of south-central Kenya, near Mount Kenya. Numbering  some six million, they are the largest ethnic group in Kenya. They tra�  ditionally lived in separate domestic family homesteads, but during the  Mau Mau rebellion the British colonial government moved them into vil�  lages for security purposes, and this arrangement became permanent.  Their traditional economy rested on intensive hoe cultivation of millet and  other crops; the main modem cash crops are coffee, corn, and fruits and  vegetables. Many Kikuyu serve in government posts.</p><p>Kilauea V.ke-lau-'a-oX Crater, eastern side of Mauna Loa, Hawaii Volca�  noes National Park, U.S. The world�s largest active volcanic crater, it is  about 3 mi (5 km) long, 2 mi (3.2 km) wide, and 500 ft (150 m) deep,  lying at an altitude of 4,090 ft (1,250 m). In its floor is the vent known  as Halemaumau Pit, legendary home of the fire goddess Pele. Its frequent  eruptions are usually contained within the vent as a boiling lake of lava,  but occasionally the lava escapes; since 1983 a series of emptions pro�  duced lava that reached the sea 30 mi (48 km) away.</p><p>Kilburn, Tom (b. Aug. 11, 1921, Dewsbury, Yorkshire, Eng.�d. Jan.  17, 2001, Manchester) British computer scientist. His book A Storage  System for Use with Binary Digital Computing Machines (1947) influ�  enced several U.S. and Russian organizations to adopt his techniques.  With Frederic C. Williams (1911-77) he designed and built the Manches�  ter Mark I (1949), the first stored-program computer, which led to the first  commercial computer, the Ferranti Mark I (1949). In 1964 he formed  Britain�s first university computer science department and became its first  professor. See also stored-program concept.</p><p>Kilby, Jack (St. Clair) (b.

In 1958 he joined Texas Instruments; there he built the first  integrated circuit, a device in which all of a circuit�s components are inte�  grated on a single semiconductor surface. He also coinvented a handheld  calculator with a thermal printer that is used in portable data terminals.  The owner of more than 60 patents, he received the National Medal of  Science (1970), the Kyoto Prize (1993), and the Nobel Prize for Physics  (2000), shared with Herbert Kroemer and Zhores Alferov.</p><p>kilim \ke-'lem\ Pileless floor covering handwoven by tapestry techniques  in Anatolia, the Balkans, and parts of Iran. The name is also given to a  variety of brocaded, embroidered, warp-faced, and other flat-woven rugs  and bags. A common characteristic is a slit that occurs wherever two  colours meet along a vertical line in the pattern. The finest examples are  silk 16th-17th-century pieces from Kashan, Iran. The largest kilims are  produced in Turkey, as are smaller examples and prayer kilims (prayer  rugs); Turkish weavers often use cotton for the white areas, and small  details may be brocaded. The kilims of the southern Balkans, originally  copies of Turkish types, gradually developed individual styles. Kilims  become progressively less Asian in colour and pattern as the distance from  Turkey increases.</p><p>Kilimanjaro V.ki-b-msn-'ja-roV  Volcanic mountain, northeastern  Tanzania. Situated in Kilimanjaro  National Park (established 1973), it  includes the peaks of three extinct  volcanoes: Kibo, Mawensi, and  Shira. Its highest peak is Kibo, which  rises to 19,340 ft (5,895 m) and is the  highest point in Africa. The first  Europeans to see Kilimanjaro were  German missionaries (1848). Kibo  was first scaled in 1889 and Mawensi  (16,896 ft [5,150 m]) in 1912.</p><p>killdeer Bird ( Charadrius vocif-  erus ) that frequents grassy mudflats.</p><p>pastures, and fields. Its name is suggestive of its loud, insistent whistle.  It is about 10 in. (25 cm) long and has a brown back, a white belly, and  two black breast bands. Killdeers breed throughout North America and in  northwestern South America. They migrate only to escape snow, return�  ing before most songbirds. They eat beetles, grasshoppers, dragonflies,  and other insects. To protect their young from predators, killdeers will  feign injury and flutter awkwardly away from the nest, luring predators  with the promise of an easy kill.</p><p>killer whale or orca A species ( Orcinus orca ) of toothed whale found  in all seas from the Arctic to the Ant�  arctic. Largest of the dolphins, the  male may be 30 ft (9 m) long and  weigh over 10,000 lbs (4,500 kg).</p><p>The killer whale is black, with white  on the underparts, above each eye,  and on each flank. The snout is blunt,  and the strong jaws have 40-50  large, sharp, conical teeth. Killer  whales live in groups of a few to  about 50 individuals. They feed on  fishes, cephalopods, penguins, and  marine mammals; though they are  fierce predators of seals and even  other whales, there is no recorded  instance of a killer whale attacking a  human. They are often kept in cap�  tivity and trained as performers in  marine shows.</p><p>killifish Any of a few hundred species of egg-laying topminnows (see  guppy) in the family Cyprinodon-  tidae. They are found worldwide in  brackish, salt, and fresh water,  including desert hot springs. Some  species grow to 6 in.

He became  the European champion in 1965, and in 1966 he won the world combined  championship (downhill, slalom, and giant slalom). In 1967 he won the  first World Cup for men, repeating this triumph in 1968. In the 1968 Win�  ter Olympics he became the second skier in history to sweep the Alpine  events (after Austria�s Toni Sailer in 1956). He retired in 1968 but returned  as a professional in 1972.</p><p>kiln Vkiln, 'kil\ Oven for firing, drying, baking, hardening, or burning a  substance, particularly clay products but originally also grain and meal.

It is made of permanently  pleated wool and wrapped around the wearer�s waist so that the pleats are  in the back and the flat ends overlap in front. It is usually worn with the  plaid, a rectangular length of cloth draped over the left shoulder. Both kilt  and plaid are woven with a tartan pattern. The ensemble, which devel�  oped in the 17th century, is worn for ordinary purposes as well as for  special occasions. Highland dress is the uniform of Scottish regiments in  the British army; kilts were worn into battle as recently as World War II.</p><p>Kilwa (Kisiwani) \'kel-wa\ Historical Islamic city-state, located on an  island off the coast of what is now southern Tanzania.

Jan. 6, 1924, Hayi-do, Korea) South  Korean politician and the first opposition leader to become president. He  first entered politics in 1954, opposing the policies of Syngman Rhee, but  did not win a seat in government until 1961. After being arrested several  times in the 1970s, Kim was sentenced to death on charges of sedition  and conspiracy; that sentence was commuted to 20 years in prison. In  1985, after a brief exile in the U.S., he resumed his role as a leader of  the political opposition. In 1997 he was elected president of South Korea,  serving from 1998 to 2003. In 2000 he received the Nobel Prize for Peace.</p><p>Kim ll-sung Vkim-'il-'surjV (b. April 15, 1912, Man�gyondae, Korea�d.  July 8, 1994, P�yongyang) Communist leader of North Korea from 1948  until his death. When Korea was effectively divided between a Soviet-  occupied northern half and a U.S.-supported southern half at the end of  World War II, Kim Il-sung helped establish a communist provisional gov�  ernment and became its first premier. He invaded South Korea in an  attempt to reunify the country, but the subsequent Korean War ended  without reunification. After the war, Kim introduced a philosophy of self-  reliance ( juche ) under which North Korea tried to develop its economy  with little help from foreign countries. His omnipresent personality cult  enabled him to rule unchallenged for 46 years in one of the world�s most  isolated and repressive societies.</p><p>Kim Jong ll Vkim-'chaq-'iH or Kim Chong II (b. Feb. 16, 1941, Sibe�  ria, Russia, U.S.S.R.) Son of Kim Il-sung. He was designated his father�s  successor in 1980 and became North Korea�s de facto leader on his  father�s death in 1994. Known in North Korea as the Dear Leader, he  makes few public appearances. After the onset of a severe famine (1995�  98), he began to relax his country�s extreme isolationism.</p><p>Kim Young Sam Vkim-'yoq-'samX (b. Dec. 20, 1927, Koje Island [near  Pusan], Korea) South Korean moderate opposition leader who served as  president (1993-98) after his party merged with the ruling party. First  elected to South Korea�s National Assembly in 1954, he served there until  his expulsion in 1979 by Pres. Park Chung Hee, which touched off riots  and demonstrations that preceded Park�s assassination. After the military  takeover by Gen. Chun Doo Hwan in 1980, Kim was put under house  arrest until 1983. In 1990 he merged his party with the ruling Democratic  Justice Party, a move that helped him win the presidency in 1992. He  enacted reforms to end political corruption, and his term was one of ris�  ing prosperity for Korea until 1997, when Korea became caught up in an  Asian financial crisis.</p><p>Kimberley City (pop., 2005 est.: urban area, 185,000), South Africa.  It is the capital of Northern Cape province. Founded in 1871 shortly after  the discovery of diamonds in the area, it was the capital of Griqualand  West (1873-80) before it became part of Cape Colony. It was besieged  by the Boers for four months (1899-1900) during the South African War.  Kimberley is home to several historical memorials and museums that  honour its diamond-mining past. It is still a centre for mining and cutting  diamonds. Its outskirts are marked by immense pits and heaps of earth,  the aftermath of mining operations. The now-defunct Kimberley mine  (now called the Big Hole) is nearby.</p><p>kimberlite or blue ground Dark, heavy, often fragmented igneous  rock that may contain diamonds in the rock matrix. Kimberlite is a mica  peridotite, an ultrabasic rock type with a complex and often highly altered  mineral composition.

The essential kimono is an ankle-  length gown with long, full sleeves and a V-neck. It is lapped left over  right across the chest and secured at the waist by a broad sash known as  an obi. The contemporary wide obi dates only from the 18th century.  Though the kimono is originally of Chinese origin, its great beauty is  attributable to 17th- and 18th-century Japanese designers.</p><p>kindergarten School or class intended for children age four to six as  a prominent part of preschool education. The kindergarten originated in  the early 19th century as an outgrowth of the ideas and practices of Rob�</p><p>ert Owen in Britain, Johann Heinrich Pestalozzi in Switzerland and his pupil  Friedrich Froebel (who coined the term) in Germany, and Maria Montessori  in Italy. Kindergartens generally stress the social and emotional growth  of the child, encouraging self-understanding through play activities and  creative expression.</p><p>Kindi, al- in full Yakub ibn Ishaq al-Sabah al-Kindi (died c.  870) First prominent Islamic philosopher. He worked in Iraq under the  caliphs al-MAMUN and al-Mutasim. One of the first Arab students of the  Greek philosophers, he translated important Greek works into Arabic and  tried to combine the views of Plato and Aristotle into a new system. His  short treatises considered the philosophical questions set forth by Neo�  platonism. He also wrote over 270 scientific treatises on such subjects as  astrology, Indian arithmetic, sword manufacturing, and cooking.</p><p>kinematics \ l ki-n3-'ma-tiks\ Branch of physics concerned with the geo�  metrically possible motion of a body or system of bodies, without con�  sideration of the forces involved. It describes the spatial position of bodies  or systems, their velocities, and their acceleration. See also dynamics.</p><p>kinesiology \ki-,ne-ze-'a-l3-je\ Study of the mechanics and anatomy  of human movement and their roles in promoting health and reducing dis�  ease. Kinesiology has direct applications to fitness and health, including  developing exercise programs for people with and without disabilities,  preserving the independence of older people, preventing disease due to  trauma and neglect, and rehabilitating people after disease or injury. Kine�  siologists also develop more accessible furniture and environments for  people with limited movement and find ways to enhance individual and  team efficiency. Kinesiology research encompasses the biochemistry of  muscle contraction and tissue fluids, bone mineralization, responses to  exercise, how physical skills are developed, work efficiency, and the  anthropology of play.</p><p>kinetic energy \ko-'net-ik\ Form of energy that an object has by rea�  son of its motion. The kind of motion may be translation (motion along  a path from one place to another), rotation about an axis, vibration, or any  combination of motions. The total kinetic energy of a body or system is  equal to the sum of the kinetic energies resulting from each type of  motion. The kinetic energy of an object depends on its mass and velocity.  For instance, the amount of kinetic energy KE of an object in translational  motion is equal to one-half the product of its mass m and the square of  its velocity v, or KE = Vimv 2 , provided the speed is low relative to the  speed of light. At higher speeds, relativity changes the relationship.</p><p>kinetic sculpture Sculpture in which movement (as of a motor-driven  part or a changing electronic image) is a basic element. Actual movement  became an important aspect of sculpture in the 20th century. Pioneers such  as Naum Gabo, Marcel Duchamp, Laszlo Moholy-Nagy, and Alexander  Calder produced movement by such means as water, mechanical devices,  and air currents (as in Calder�s mobiles). Neo-Dadaist works such as Jean  Tinguely�s self-destructing Homage to New York (1960) embody the con�  cept of a sculpture that functions as both an object and an event�a �hap�  pening.�</p><p>kinetic theory of gases Theory based on a simple description of a  gas, from which many properties of gases can be derived. Established pri�  marily by James Clerk Maxwell and Ludwig Boltzmann, the theory is one of  the most important concepts in modern science. The simplest kinetic  model is based on the assumptions that (1) a gas is composed of a large  number of identical molecules moving in random directions, separated by  distances that are large compared to their size; (2) the molecules undergo  perfectly elastic (no energy loss) collisions with each other and with the  walls of the container; and (3) the transfer of kinetic energy between mol�  ecules is heat. This model describes a perfect gas but is a reasonable  approximation to a real gas. Using the kinetic theory, scientists can relate  the independent motion of molecules of gases to their pressure, volume,  temperature, viscosity, and heat conductivity.</p><p>king Male sovereign over a nation or territory, of higher rank than any  other ruler except an emperor. A king�s female counterpart is a queen.  Some kings have been elected, as in medieval Germany, but most inherit  the position. The community may concentrate all spiritual and political  power in the sovereign, or power may be shared constitutionally with  other government institutions. Some kings are heads of state but not heads  of government. In the past, some were regarded as semidivine represen�  tatives of God on Earth; others were viewed as gods in their own right or  supernatural beings who became gods after death (see divine kingship).</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>King &#x25BA; king crab I 1037</p><p>Since the 17th century the power held by monarchs, particularly those in  western Europe, has been widely regarded as deriving from the people.

Jan. 15, 1929, Atlanta, Ga., U.S.�d.  April 4, 1968, Memphis, Tenn.) U.S.  civil-rights leader. The son and  grandson of Baptist preachers. King  became an adherent of nonviolence  while in college. Ordained a Baptist  minister himself in 1954, he became  pastor of a church in Montgomery,</p><p>Ala.; the following year he received  a doctorate from Boston University.</p><p>He was selected to head the Mont�  gomery Improvement Association,  whose boycott efforts eventually  ended the city�s policies of racial seg�  regation on public transportation. In  1957 he formed the Southern Chris�</p><p>tian Leadership Conference and began lecturing nationwide, urging active  nonviolence to achieve civil rights for African Americans. In 1960 he  returned to Atlanta to become copastor with his father of Ebenezer Bap�  tist Church. He was arrested and jailed for protesting segregation at a  lunch counter; the case drew national attention, and presidential candi�  date John F. Kennedy interceded to obtain his release. In 1963 King helped  organize the March on Washington, an assembly of more than 200,000  protestors at which he made his famous �I have a dream� speech. The  march influenced the passage of the Civil Rights Act of 1964, and King  was awarded the 1964 Nobel Prize for Peace. In 1965 he was criticized  from within the civil-rights movement for yielding to state troopers at a  march in Selma, Ala., and for failing in the effort to change Chicago�s  housing segregation policies. Thereafter he broadened his advocacy,  addressing the plight of the poor of all races and opposing the Vietnam  War. In 1968 he went to Memphis, Tenn., to support a strike by sanita�  tion workers; there on April 4, he was assassinated by James Earl Ray. A  U.S. national holiday is celebrated in King�s honour on the third Mon�  day in January.</p><p>King, Rufus (b. March 24, 1755, Scarborough, Mass.�d.

Upon his return,  he moved to Alabama and became one of the state�s first U.S. senators  (1819-44, 1848-52). As minister to France from 1844 to 1846, he con�  vinced the French government not to interfere with the U.S. annexation  of Texas. In 1852 he was elected U.S. vice president under Franklin Pierce,  but he died shortly after taking the oath of office.</p><p>King Cotton Phrase used before the American Civil War to denote the  economic importance of Southern cotton production. The concept first  appeared in the book Cotton Is King (1855) and was echoed by Southern  politicians, who believed that cotton�s economic and political power  would bring victory if secession led to war. The South expected support  from Britain, a major cotton importer, but Britain instead developed alter�  native sources of cotton within its empire.

By 1660 colonial  settlers, no longer dependent on Indians for survival, had pushed into  Indian territory in Massachusetts, Connecticut, and Rhode Island. To pro�  tect their lands, the Wampanoag chief King Philip (Metacom) organized  a federation of tribes, which in 1675 destroyed several frontier settle�  ments. In retaliation the colonial militia burned Indian villages and crops.  After Philip�s death in 1676, Indian resistance collapsed. An estimated  600 settlers and 3,000 Indians were killed in the conflict.</p><p>king salmon See chinook salmon</p><p>king snake Any of seven species of snake (genus Lampropeltis, fam�  ily Colubridae) found in numerous  habitats from southeastern Canada to  Ecuador. They kill by constriction;  named for their practice of eating  other snakes, they also take small  mammals, amphibians, birds, and  birds� eggs. They are mainly terres�  trial and relatively slow-moving.</p><p>Strikingly marked and smooth-  scaled, they have a small head and  are usually less than 4 ft (1.2 m)  long, though some specimens may  approach 7 ft (2 m). The common  king snake, found throughout the  U.S. and in northern Mexico, is usu�  ally black or dark brown, variously  blotched, ringed, or speckled with  yellow or white.</p><p>King William's War (1689-97) Battle for North American territory  between Britain, under King William III, and France. The war, which was  the North American extension of the War of the Grand Alliance, involved  French Canadians and New England colonists and their Indian allies. The  British captured Port Royal, Acadia (later Nova Scotia), but failed to take  Quebec. The French, under the count de Frontenac, won skirmishes at  Schenectady, N.Y., and in New England but failed to take Boston. The  war ended with the Treaty of Rijswijk (1697). See also French and Indian  War.</p><p>kingdom of God or kingdom of heaven In Christianity, the spiri�  tual realm over which God reigns as king, or the eventual fulfillment of  God�s will on earth. Although rare in pre-Christian Jewish literature, the  idea of God as king was fundamental to Judaism, and Jewish ideas on the  kingdom of God most likely shaped New Testament usage. The term is  often used in the New Testament, and it was a central theme in the preach�  ing of John the Baptist and Jesus. Theologians differ as to whether Jesus  implied that the kingdom had arrived in his person or whether it was  expected as a future event. Christian orthodoxy now holds that the king�  dom has been partially realized by the presence of the church in the world  and that it will be fully realized after the Last Judgment.</p><p>kingfish Any of various fishes, among them certain species of mackerel  and a drum. The king mackerel, or kingfish ( Scomberomorus cavalla), is  a western Atlantic fish about 67 in. (170 cm) long and weighing 79 lbs  (36 kg) or more. The kingfish, or whiting ( Menticirrhus saxatilis ), of the  Atlantic, is notable among drums in that it lacks an air bladder.</p><p>kingfisher Any of about 90 species of birds (family Alcedinidae), many  of which fish for their food. Solitary birds, kingfishers are found world�  wide but are chiefly tropical. They have a large head, long and usually  narrow bill, compact body, small feet, and usually a short or medium-  length tail. Species range from 4 to 18 in. (10�45 cm) long; most have  bright, boldly patterned plumage, and many are crested. They utter rat�  tling or piping calls, and they plunge into the water for small fish and  other aquatic animals. The only widespread North American species, the  belted kingfisher ( Megaceryle alcyon), is bluish gray above and white  below. The forest kingfishers (e.g., kookaburra) have a broader bill.</p><p>Kings, Valley of the Narrow gorge. Upper Egypt, near the ancient city  of Thebes. It is the burial site of nearly all of the kings (pharaohs) of the  18th-20th dynasties (1539-1075 bc), from Thutmose I to Ramses X. The  valley contains 62 tombs, virtually all of which were robbed in antiquity.  Only the tomb of Tutankhamen escaped pillage; after its excavation in the  1920s, its treasures were placed in the Egyptian Museum in Cairo. The  longest tomb belongs to Queen Hatshepsut, whose burial chamber is nearly  700 ft (215 m) from the entrance. The largest tomb, built for the sons of  Ramses II, contains scores of burial chambers. The valley is part of a  UNESCO World Heritage site (designated 1979) centred on Thebes.</p><p>Kings Canyon National Park National park, Sierra Nevadas, south-  central California, U.S. Occupying an area of 722 sq mi (1,870 sq km), it  is administered along with the adjacent Sequoia National Park.

Its most spectacular feature is Kings  Canyon on the Kings River, which was carved by glacial action.</p><p>Kings Mountain, Battle of (Oct. 7, 1780) Battle in the American  Revolution between American revolutionaries and loyalists. About 2,000  frontiersmen were assembled to resist the British advance into North  Carolina; they surrounded the 1,100 soldiers, mainly loyalists from New  York and South Carolina, on Kings Mountain, S.C., near the border with  North Carolina. The frontiersmen killed or captured almost all the loyal�  ists, and the battle marked the beginning of the war�s turn against the  British.</p><p>kingship, divine See divine kingship</p><p>Kingsley, Charles (b.

After studies at Cambridge, he became a parish priest and later  chaplain to Queen Victoria, professor of modern history at Cambridge,  and canon of Westminster. An enthusiastic advocate of Christian socialism,  he published several novels about social problems before writing the very  successful historical novels Hypatia (1853), Westward Ho! (1855), and  Hereward the Wake (1866). Fearing the Anglican church�s trend in the  direction of Catholicism, he engaged in a famous controversy with John  Henry Newman. His wholehearted acceptance of Charles Darwin�s theory  of evolution inspired his popular children�s book The Water-Babies</p><p>(1863).</p><p>Kingston City (pop., 1999 est.: metro, area, 655,000), capital and chief  port of Jamaica. Located on the southeastern coast of the island, it was  founded in 1692 after Port Royal was destroyed by an earthquake. It soon  became the commercial centre of Jamaica and was made the political  capital in 1872. Historic buildings include a 17th-century church, a  moated fortress, and the 18th-century Headquarters House. It is the seat  of the University of the West Indies.</p><p>Kingston, Maxine Hong orig.

Her widely admired The Woman Warrior (1976) and  China Men (1980) blend fact and fantasy to tell aspects of her family�s  history.</p><p>Kingston upon Hull or Hull City and unitary authority (pop., 2001:  243,595), geographic county of East Riding of Yorkshire, historic county  of Yorkshire, England. It lies on the northern bank of the River Humber at  its junction with the River Hull, 22 mi (35 km) from the North Sea. Hull  was a medieval wool port that passed from the monks of Meaux Abbey  to Edward I in 1293. For more than 400 years it was the chief shipping  port for the inland waterways converging on the River Humber. Granted  city status in 1897, it is a major national seaport, accommodating large  oceangoing vessels. The medieval part of the city retains a number of his�  toric buildings; its grammar school was founded in 1486.</p><p>Common king snake (Lampropeltis get-  ula).</p><p>JACK DERMID</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Kingstown &#x25BA; Kiribati I 1039</p><p>Kingstown Capital (pop., 1999 est.: 16,175), chief port of Saint Vin�  cent and the Grenadines, West Indies.

March 28, 1942, Tredegar, Monmouth�  shire, Wales) British politician. Elected to Parliament in 1970, he rose in  the Labour Party ranks and was named to its national executive commit�  tee in 1978. After the party suffered its heaviest defeat in 48 years in 1983,  he was elected party leader, the youngest in its history. By 1989 he had  persuaded the party to abandon its radical policies on disarmament and  large-scale nationalization. Although the party increased its numbers in  Parliament, it lost the 1992 general election to the Conservatives, and  Kinnock resigned as party leader. He became a vice president of the  European Commission of the European Union in 1999.</p><p>Kinsey Vkin-zeV Alfred (Charles) (b. June 23, 1894, Hoboken, N.J.,  U.S.�d. Aug. 25, 1956, Bloomington, Ind.) U.S. zoologist and expert on  human sexual behaviour. After earning a Ph.D. from Harvard University  in 1920, he taught zoology at Indiana University, where he became the  founder-director, in 1942, of the university�s Institute for Sex Research  (renamed the Kinsey Institute for Sex Research, Inc., in 1981). His inquir�  ies into human sexuality led him to publish Sexual Behavior in the Human  Male (1948) and Sexual Behavior in the Human Female (1953). These  reports, based on 18,500 personal interviews, received extraordinary pub�  licity for their conclusions about contemporary sexual mores and behav�  iour. Kinsey�s methodologies and statistical samplings, however, have  been highly questioned and criticized in recent years.</p><p>Kinsha River See Jinsha River</p><p>Kinshasa \kin-sh'a-SQ\formerly Leopoldville Capital and largest city  (pop., 1994 est.: 4,655,313), Democratic Republic of the Congo.

After World War II it emerged as the largest city in  sub-Saharan Africa and became the capital of the independent republic in  1960. It was given its present name in 1966. A major river port and a  commercial centre, it is the seat of the University of Kinshasa (1954).</p><p>kinship Socially recognized relationship between people who are or are  held to be biologically related or who are given the status of relatives by  marriage, adoption, or other ritual. Kinship is the broad term for all the  relationships that people are born into or create later in life that are con�  sidered binding in the eyes of society. Every person belongs to a family  of orientation (e.g., mother, father, brothers, and sisters); many adults also  belong to a family of procreation (which includes a spouse or spouses and  children). Familial bonds of descent and marriage may be traced through  a genealogy, a written or oral statement of the names of individuals and  their kin relations to one another. Inheritance and succession (the trans�  mission of power and position in society) usually follow kinship lines.  See also exogamy and endogamy; incest.</p><p>kiosk \'ke-ask\ Originally, in Islamic architecture, an open circular pavil�  ion consisting of a roof supported by pillars.

Their  language is of Kiowa-Tanoan language stock. The name Kiowa may be a  variant of their name for themselves, Kai-i-gwu, meaning �Principal  People.� The Kiowa moved southward from western Montana and adopted  the lifestyle of the Pains Indians. They hunted buffalo on horseback and  lived in large three-poled tepees. They had warrior societies, the members of  which attained rank according to their exploits in war. They believed that  dreams and visions gave them supernatural power, and they participated in  the sun dance ceremony. They were also noted for their pictographic por�  trayals, or �calendar histories,� of important tribal events. They were  among the last of the Plains peoples to capitulate to the U.S. Some 8,600  peoples claimed sole Kiowa descent in the 2000 U.S. census.</p><p>Kipling, (Joseph) Rudyard (b. Dec. 30, 1865, Bombay, India�d.  Jan. 18, 1936, London, Eng.) Indian-born British novelist, short-story  writer, and poet. The son of a museum curator, he was reared in England</p><p>but returned to India as a journalist.</p><p>He soon became famous for volumes  of stories, beginning with Plain Tales  from the Hills (1888; including �The  Man Who Would Be King�), and  later for the poetry collection  Barrack-Room Ballads (1892;  including �Gunga Din� and �Manda�  lay�). His poems, often strongly  rhythmic, are frequently narrative  ballads. During a residence in the  U.S., he published a novel, The Light  That Failed (1890); the two Jungle  Book s (1894, 1895), stories of the  wild boy Mowgli in the Indian jungle  that have become children�s classics;  the adventure story Captains Coura�  geous (1897); and Kim (1901), one  of the great novels of India. He wrote  six other volumes of short stories and  several other verse collections. His Rudyard Kipling.</p><p>children�s books include the famous ELLIOTTANDFRY _</p><p>Just So Stories (1902) and the fairy�  tale collection Puck of Pook�s Hill (1906).

His extraordinary popularity in his own time  declined as his reputation suffered after World War I because of his wide�  spread image as a jingoistic imperialist.</p><p>Kirchhoff \'kirk-hof\, Gustav Robert (b. March 12, 1824, Konigs-  berg, Prussia�d. Oct. 17, 1887, Berlin, Ger.) German physicist. Kirch�  hoff�s laws (1845) allow calculation of the currents, voltages, and  resistances of electrical networks (he was the first to show that current  flows through a conductor at the speed of light) and generalized the equa�  tions describing current flow to three dimensions. With Robert Bunsen, he  demonstrated that every element emits coloured light when heated at wave�  lengths specific to it, a fact that is the basis of spectrum analysis. They  used this new research tool to discover cesium (1860) and rubidium (1861),  and began a new era in astronomy when they applied it to the spectrum of  the sun.</p><p>Kirchhoff's circuit rules Vkir-,k6fs\ or Kirchhoff's laws Two</p><p>statements, developed by Gustav Kirchhoff, about complex circuits that  embody the laws of conservation (see conservation aw) of electric charge  and energy. They are used to determine the value of the electric current in  each branch of the circuit. The first law states that the sum of the currents  into a junction in the circuit equals the sum of the currents out of the  junction. The second law states that around each loop in an electric cir�  cuit, the sum of the electromotive force is equal to the sum of all the poten�  tial drops (changes in voltage) across components in the loop. Using these  rules, algebraic equations can be formulated to determine the value of  currents in different loops in a circuit.</p><p>Kirchner Vkirk-norV Ernst Lud�  wig (b.

Kirchner� s  highly personal style, influenced by  Albrecht Durer, Edvard Munch, and  African and Polynesian art, was  noted for its psychological tension  and eroticism. He used simple, pow�  erfully drawn forms and often garish  colours to create intense, sometimes  threatening works, such as his two  versions of Street, Berlin (1907,</p><p>1913). Highly strung and often  depressed, he took his own life when  the Nazis declared his work �degen�  erate.�</p><p>Kiribati X.kir-o-'ba-te, ,kir-i-'bas,</p><p>'kir-i-,bas\ officially Republic of  Kiribati Island country, central</p><p>Street, Berlin, oil on canvas by Ernst  Ludwig Kirchner, 1913; in the Museum  of Modern Art, New York City.</p><p>COURTESY OF THE MUSEUM OF MODERN ART, NEW YORK  CITY</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1040 I Kirin &#x25BA; Kitakami Mountains</p><p>Pacific Ocean. It consists of 33 islands. The three major island groups are  the Gilbert, Phoenix, and Line islands (excluding the three Line Islands that  are U.S. territories); Kiribati also includes Banaba Island, the former capi�  tal of the Gilbert and Ellice Islands colony. Area (land): 313 sq mi (811 sq  km). Population (2005 est.): 95,300. Capital: Bairiki, on Tarawa Atoll. The  indigenous people are mostly Micronesians. Languages: English (official),  Gilbertese. Religions: Christianity (mostly Roman Catholic; also Protes�  tant); also Baha�i. Currency: Australian dollar. With the exception of  Banaba (which is a coral island and higher in elevation), all the islands  of Kiribati are low-lying coral atolls built on a submerged volcanic chain  and encircled by reefs. Only about 20 of the islands are inhabited; nearly  all of the population of Kiribati live in the Gilbert Islands. The economy  is based on subsistence farming and fishing. Kiribati is a republic with  one legislative house; its head of state and government is the president.  The islands were settled by Austronesian-speaking people before the 1st  century ad. Fijians and Tongans arrived c. the 14th century. In 1765 the  British commodore John Byron discovered the island of Nikunau; the first  permanent European settlers arrived in 1837. In 1916 the Gilbert and  Ellice Islands and Banaba became a crown colony of Britain; the Phoe�  nix Islands joined the colony in 1937. Most of the Line Islands joined the  colony in 1972, but in 1976 the Ellice Islands were separated and in 1978  formed the country of Tuvalu. The colony became self-governing in 1977,  and in 1979 it became the Republic of Kiribati.</p><p>Kirin See Jilin</p><p>Kiriwina Islands See Trobriand Islands</p><p>Kirkland, (Joseph) Lane (b.

After  joining the Bolsheviks, he extended the Communist Party�s control in Trans�  caucasia, and in 1926 Joseph Stalin appointed him head of the Leningrad  party organization (1926). He modernized the city�s industries, was  elected to the Politburo (1930), and acquired power that nearly rivaled  Stalin�s. In 1934 he was assassinated by a young party member, Leonid  Nikolayev, who was later shot, along with 13 suspected accomplices. Sta�  lin, claiming that a widespread conspiracy of anti-Stalinist communists  planned to assassinate the entire Soviet leadership, used the assassination  as a pretext to institute the Purge trials.

Trained as a military engineer, Kitchener served  in posts in the Middle East and Sudan before being appointed commander  in chief of the Egyptian army in 1892. In 1898 he crushed the rebellious  Mahdist movement in the Battle of Omdurman and forced concessions from  France in the Fashoda Incident. He entered the South African War as chief  of staff in 1899, becoming commander in chief a year later. In the last 18  months of the war, he resorted to brutal methods, burning Boer farms and  herding Boer women and children into concentration camps. He was later  sent to India to reorganize the army there. A clash with Lord Curzon over  control of the army resulted in Curzon�s resignation in 1905. In 1911  Kitchener returned to Khartoum as proconsul of Egypt and the Sudan. As  secretary of state for war during World War I, he organized armies on a  scale unprecedented in British history and became a symbol of the  national will to victory. He died on a mission to Russia when his ship was  sunk by a German mine.</p><p>kite Light frame covered with paper or cloth, often provided with a bal�  ancing tail, and designed to be flown in the air at the end of a long string;  it is held aloft by wind. Its name comes from the kite, a member of the  hawk family. Kites have been in use in Asia from time immemorial, and  religious significance is still connected to some ceremonial kite-flying  there. In a famous experiment in 1752, Benjamin Franklin hung a metal  key from a kite line during a storm to attract electricity. Kites were used  to carry weather-recording devices aloft before the advent of balloons and  airplanes. Types of kite commonly in use today include the hexagonal (or  three-sticker), the malay (modified diamond), and the box kite, invented  in the 1890s. Newer wing-like kites, with pairs of controlling strings for  superior maneuverability, are also flown.</p><p>kite Any of numerous lightly built birds of prey that have a small head,  partly bare face, short beak, and  long, narrow wings and tail. They are  found worldwide in warm regions.</p><p>Some live on insects; others are pri�  marily scavengers but also eat  rodents and reptiles; a few eat only  snails. In flight, kites slowly flap and  then glide with wings angled back.</p><p>Kites belong to three subfamilies of  the family Accipitridae: Milvinae  (true kites and snail kites), Elaninae  (including the white-tailed kite, one  of the few North American raptors  increasing in number), and Perninae  (including the swallow-tailed kite of  the New World). See also hawk.</p><p>kithara Vki-tho-roX Large lyre of Classical antiquity, the principal  stringed instrument of the Greeks and later of the Romans. It had a box�  shaped resonating body from which extended two parallel arms connected  by a crossbar to which 3-12 strings were attached. It was held vertically  and plucked with a plectrum; the left hand was used to stop and damp the  strings. It was played by singers of the Greek epics, as well as by later  professional accompanists and soloists.</p><p>kittiwake or black-legged kittiwake White oceanic gull (Rissa  tridactyla ) with pearl-gray mantle, black-tipped wings, black feet, and  yellow bill. Kittiwakes nest on narrow cliff ledges along the North and  South Atlantic coasts. The red-legged kittiwake ( R. brevirostris ) is found  in the Bering Sea region.</p><p>kiva \'ke-v9\ Underground chamber of the Pueblo Indian villages of the  southwestern U.S., notable for the murals that decorate its walls. A small  hole in its floor, the sipapu, serves as the symbolic place of origin of the  tribe. Though the kiva�s primary purpose is for ritual ceremonies, men  also use it for political meetings or casual gatherings. Women are almost  always excluded from the kiva. The traditional round slope of the earli�  est kiva, in contrast to the otherwise square or rectangular Pueblo archi�  tecture, recalls the circular pit houses of the prehistoric basket-weaving  culture from which these tribes, primarily Hopi and Zuni, descend.</p><p>Kivu \ke-vu\, Lake Lake, central East Africa. Located between Rwanda  and the Democratic Republic of the Congo (Zaire), it occupies 1,040 sq  mi (2,700 sq km), is 55 mi (90 km) long and 30 mi (48 km) wide, and  has a maximum depth of 1,558 ft (475 m). Containing many islands, it  was part of a larger body of water until volcanic outpourings along its  northern shore created a dam that separated it from Lake Edward.</p><p>kiwi Any of three species (genus Apteryx ) of chicken-sized, grayish  brown ratite birds, found in New  Zealand. Their Maori name refers to  the male�s shrill call. Kiwis have  vestigial wings hidden within the  plumage; nostrils at the tip (rather  than the base) of the long flexible  bill; soft, hairlike feathers; and stout,  muscular legs. Each of the four toes  has a large claw. Kiwis live in for�  ests, where they sleep by day and  forage for worms, insects and their  larvae, and berries at night. They run  swiftly and use their claws in defense  when cornered.</p><p>kiwi fruit Edible fruit of the vine Actinidia chinensis (family Actinid-  iaceae), native to China and Taiwan and grown commercially in New  Zealand and California. It became popular in the nouvelle cuisine of the  1970s. It has a slightly acid taste and is high in vitamin C. Kiwi can be  eaten raw or cooked, and the juice is sometimes used as a meat tender-  izer.</p><p>Kiyomori See Taira Kiyomori</p><p>KiziI \ki-'zil\ River ancient Halys River River, central and north-  central Turkey.

It lies on the channel that connects the  Neman River with the Baltic Sea. A fortress built on the site in the early  13th century was destroyed in 1252 by the Teutonic Order, who built a  new fortress called Memelburg. It came under Prussian control in the 17th  century, and the town (Memel) was settled by Germans. In 1923 Memel  became part of Lithuania and was renamed Klaipeda. Seized by Germany  in 1939, it passed to the Soviet Union in 1945. Klaipeda became part of  the newly independent Lithuania in 1991. The modem city has major  shipbuilding yards and is the base for a large deep-sea fishing fleet.</p><p>Klamath Vkla-mothX North American Plateau Indian people living  mainly in Oregon, U.S. The name Klamath may be a variant of their name  for the region (spelled Clemmat or Tlamath); it is the name by which they  were known to the Chinook. They called themselves Maqlaq, meaning  �The People,� usually with an adjective (such as Ewksikni, �of the Lake�).  They were primarily fishers and hunters of waterfowl. The Klamath were  divided into relatively autonomous villages, each with its own leaders and  medicine man; the villages would ally for war, and members of different  villages often intermarried. Families lived in earth-covered lodges in win�  ter and domed houses of poles and matting in summer. Sweat lodges</p><p>Swallow-tailed kite (Elanoides forfica-  tus).</p><p>JAMES A.

Dec. 18, 1879, Miinchenbuchsee, Switz.�d. June  29, 1940, Muralto) Swiss painter.</p><p>After studies in Germany and Italy,  he settled in Munich, where he  became associated with Der Blaue  Reiter (1911). He taught at the Bau-  haus (1920�31), then at the Diissel-  dorf Academy. He lost his post when  the Nazis came to power in 1933 and  returned to Switzerland. One of the  foremost artists of the 20th century,  he belonged to no movement, yet he  assimilated and even anticipated  some of the major artistic tendencies  of his time. Using both representa�  tional and abstract approaches, he  produced some 9,000 paintings,  drawings, and watercolours in a  great variety of styles. His works,  which tend to be small in scale, are remarkable for their delicate nuances  of line, colour, and tonality. In Klee�s highly sophisticated art, irony and  a sense of the absurd are joined to an intense evocation of the mystery  and beauty of nature. Music figures prominently in his work�in his many  images of opera and musicians, and to some extent as a model for his  compositions. But literature had the greater pull on him; his art is steeped  in poetic and mythic allusion, and the titles he gave to his pictures tend  to charge them with additional meanings. His late paintings, anticipating  his approaching death, are among his most memorable.</p><p>Kleiber Vkli-borV, Erich (b. Aug. 5, 1890, Vienna, Austria�d. Jan. 27,  1956, Zurich, Switz.) Austro-Hungarian conductor. After his Prague debut  in 1911, he held a series of posts that led him to the Berlin State Opera,  where he was music director from 1923 to 1934. There he premiered  important works such as Alban Berg�s Wozzeck (1925). When the Nazis  forbade the premiere of Berg�s Lulu (1934), he managed to program the  suite from the opera for his last concert. After moving to Buenos Aires,  he was head of the German Opera at the Teatro Colon (1937�49). His son  Carlos (b. 1930) also became an internationally celebrated conductor,  especially of opera, with a reputation for perfectionism equal to his  father�s.</p><p>Klein, Calvin (Richard) (b. Nov. 19, 1942, New York, N.Y., U.S.)  U.S. fashion designer. He attended the Fashion Institute of Technology.  He opened his own company in 1968, when casual, hippie-style clothing  was in fashion, but took a different direction by designing simple, under�  stated, elegant clothing. Though noted at first for suits and coats, he gradu�  ally placed more emphasis on sportswear, particularly interchangeable  separates. He was the first designer to win three consecutive Coty Awards  for womenswear (1973-75). Over the course of the 1980s and �90s he  became known for his clothing, cosmetics, linens, and other designer col�  lections, as well as for his erotic advertising photographs, some of which  have drawn public protest. His achievements represented the maturation  of the American fashion industry.</p><p>Klein, Melanie orig. Melanie Reizes (b. March 30, 1882, Vienna,  Austria�d. Sept. 22, 1960, London, Eng.) Austrian-British psychoana�  lyst. She married at age 21 and had three children before undergoing psy�</p><p>choanalysis with Ferenczi SAndor in Budapest, Hung. She studied the  psychoanalysis of young children, joining the Berlin Psychoanalytic Insti�  tute (1921-26) and later moving to London. In works such as The Psy�  choanalysis of Children (1932) and Narrative of a Child Analysis (1961),  she asserted that children�s play was a symbolic way of controlling anxi�  ety and that observation of free play with toys could serve as a means of  determining early psychological impulses.</p><p>Klein, Yves (b. April 28, 1928, Nice, Fr.�d. June 6, 1962, Paris) French  painter, sculptor, and performance artist. With no formal artistic training,  he began in the mid 1950s to exhibit nonobjective paintings in which a  canvas was uniformly covered in a single colour, usually blue; he also  used the technique for sculptural figures and reliefs. In 1958 he produced  a near-riot with an �exhibition of emptiness,� an empty gallery painted  white, titled The Void. He used a variety of unorthodox methods to pro�  duce pictures, such as imprints of the human body on paper or canvas  (i anthropometries ). His work was deliberately extreme and experimental.  A member of Fluxus, he greatly influenced the development of Minimal�  ism.</p><p>Kleist \'klist\, (Bernd) Heinrich (Wilhelm) von (b. Oct. 18, 1777,  Frankfurt an der Oder, Brandenburg�d. Nov. 21, 1811, Wannsee, near  Berlin) German writer. He served seven years in the Prussian army, and  his work first attracted attention when he was in prison accused as a spy.  The grim and intense drama Penthesilea (1808) contains some of his most  powerful poetry, and The Broken Pitcher (1808) is a masterpiece of dra�  matic comedy; they were followed by Katherine ofHeilbronn (1810), Die  Hermannsschlacht (1821), and The Prince of Homburg (1821). In 1811  he published a collection of eight masterly novellas, including Michael  Kohlhaas, The Earthquake in Chile, and The Marquise of O. Embittered  by a lack of recognition, he ended his unhappy life in a joint suicide with  a young woman at age 34. He is now considered the first of the great  19th-century German dramatists, and his disturbing and densely written  fictions are widely admired by writers.</p><p>Kleitias See Cleitias</p><p>Klemperer, Otto (b. May 14, 1885, Breslau, Ger.�d. July 6, 1973,  ZUrich, Switz.) German conductor. After studying composition with Hans  Pfitzner (1869-1949), in 1905 he met Gustav Mahler, who recommended  him for several positions, including chief conductor at the Hamburg Opera  (1910). At the short-lived Kroll Opera (1927-31) he conducted the Ber�  lin premieres of many important works by contemporary composers. In  1933 he fled Germany for the U.S., conducting in Los Angeles (1933-39)  and studying with Arnold Schoenberg. A brain tumour in 1939 left him  partly paralyzed. From the 1950s, though seated on the podium, he cre�  ated a much-admired recorded legacy with London�s Philharmonia  Orchestra.</p><p>Kleophrades Painter See Cleophrades Painter</p><p>klezmer music Yiddish "vessel of song" Traditional music played  by professional musicians (klezmorim) in the Jewish ghettos of eastern  Europe, especially for weddings and other ceremonies. The klezmer tra�  dition has its roots in medieval Europe. By the 19th century its style was  well-developed, influenced not only by the liturgical music of the syna�  gogue (which allows only unaccompanied singing), but also that of the  local non-Jewish cultures. It is primarily lively dance music. Klezmer  ensembles have varied considerably; in the U.S., where a klezmer revival  began in the 1980s, a typical band consists of four to six musicians play�  ing some combination of violin, clarinet, trumpet, trombone, tuba, accor�  dion, double bass, and percussion.</p><p>Klimt, Gustav (b. July 14, 1862, Vienna, Austria�d. Feb. 6, 1918,  Vienna) Austrian painter. In 1897, after a period as an academic mural-  ist, his mature style emerged. Revolting against academic art in favour of  a decorative style similar to Art Nouveau, he founded the Vienna Sez-  ession. His most successful works include The Kiss (1908) and a series  of portraits of fashionable Vienna matrons. In these works he treated the  human figure without shadow, conveying the sensuality of skin by sur�  rounding it with areas of flat, highly ornamental areas of decoration. His  later murals are characterized by precisely linear drawing and flat, deco�  rative patterns of colour and gold leaf. He greatly influenced Oskar Koko�  schka and Egon Schiele.

Testosterone is low  and pituitary reproductive hormones high. Intelligence is usually normal,  but social adjustment can be difficult. Rarer variants cause additional  abnormalities, including mental retardation. In the XX male syndrome, Y  chromosome material has been transferred to another chromosome, caus�  ing changes typical of Klinefelter syndrome.

He is known for  his use of symbol, fantasy, and dreamlike situations, reflecting a late-  19th-century awareness of psychological depths. His vivid, frequently  morbid imaginings and his interest in the gruesome and grotesque can be  seen in his Goyaesque etchings. He is best known for a series of pen-  and-ink drawings called Series upon the Theme of Christ and Fantasies  upon the Finding of a Glove, which tells a strange parable of a hapless  young man and his obsessive involvement with a woman�s elbow-length  glove. He also created controversial treatments of religious themes. In his  later years he worked primarily in sculpture. He had a deep influence on  many artists, including Edvard Munch, Kathe Kollwitz, Max Ernst, and  Giorgio de Chirico.</p><p>Klondike gold rush Canadian gold rush of the late 1890s. Gold was  discovered on Aug. 17, 1896, near the confluence of the Klondike and  Yukon rivers in western Yukon Territory. The news spread quickly, and by  late 1898 more than 30,000 prospectors had arrived. Annual production  peaked at $22 million worth of gold in 1900, and soon prospectors began  moving on to Alaska. By the time mining ended in 1966, the area had  yielded $250 million in gold.</p><p>Kluane \klu-'6-ne\ National Park National park, southwestern  Yukon, Canada.

Major U.S.  retail chain, marketing general merchandise primarily through discount  and variety stores. It originated with a pair of 5-and-10-cent stores estab�  lished in 1897 by S.S. Kresge and a partner. Kresge�s at first restricted the  price of its merchandise to not more than 10 cents, but eventually to not  more than one dollar. In 1962 Kresge�s entered the large-scale discount  retail market with construction of the first Kmart outside Detroit, Mich.  With its success, the company expanded aggressively, erecting an aver�  age of 85 discount stores per year over the next two decades. In 1977 it  became the second largest U.S. retailer. After introducing Martha Stew�  art as its spokesperson in 1987, Kmart became the exclusive retailer for  the Martha Stewart Everyday brand in 1997. Kmart declared bankruptcy,  however, in 2002 after years of increasingly damaging competition from  the world�s largest retailer, Wal-Mart, and other discount stores. It merged  with Sears, Roebuck and Co. in 2005, becoming part of Sears Holdings  Corporation.</p><p>Knesset \k9-'nes-3t\ (Hebrew: �Assembly�) Unicameral national legis�  lature of Israel.

He taught  at the University of Chicago from 1927 to 1952; Milton Friedman was one  of the many students he influenced. His book Risk, Uncertainty and Profit  (1921) distinguished between insurable and uninsurable risks and asserted  that profit was the reward entrepreneurs earned for bearing uninsurable  risk.

To pro�  tect its members from employers� reprisals, it originally maintained  secrecy. Under Terence V. Powderly (1879-93) it favoured open arbitration  with management and discouraged strikes. National membership reached  700,000 in 1886. Strikes by militant groups and the Haymarket Riot caused  an antiunion reaction that rapidly reduced the organization�s influence.

The Hospitallers acquired wealth and lands and began to combine the task  of tending the sick with waging war on Islam, eventually becoming a  major military force in the Crusades. After the fall of the crusader states,  they moved their headquarters to Cyprus and later to Rhodes (1309). They  ruled Rhodes until it fell to the Turks in 1523; thereupon they moved to  Malta, where they ruled until their defeat by Napoleon I in 1798.

The party�s precursor organization, the secret Order of the  Star-Spangled Banner, was formed in New York City in 1849 from the  anti-immigrant and anti-Roman Catholic movement, and lodges were  soon established in other major cities. Members were instructed to reply  to queries about their group with �I know nothing.� As its membership  and importance grew in the 1850s, the group slowly shed its clandestine  character and took the official name American Party. The party called for  restrictions on immigration and on naturalized citizenship. Many local and  state candidates won offices in the 1852 election, and by 1855 there were  43 Know-Nothing members of Congress. At its 1856 convention the party  split over the slavery issue; proslavery advocates left to join the Demo�  crats and antislavery adherents joined the Republicans.

Probably trained for  the priesthood at the University of  St. Andrews, he was ordained in  1540. He joined a group of Protes�  tants who fortified St. Andrews  Castle, but they were captured by  French Catholics and carried away  into slavery in 1547. Released  through English intervention in  1549, he spent four years preaching  in England, where he influenced  developments in the Church of  England. With the accession of the  Catholic Mary I, he fled to the Con�  tinent. He served as pastor at Frank�  furt am Main and Geneva until his  return to Scotland in 1559. In  England, Elizabeth I made common  cause with the Scottish Presbyteri�  ans, lest the French gain control of  Scotland to support its Catholic  monarch, Mary, Queen of Scots.

He was elected to the  U.S. Congress in 1968, and in 1978 he was elected to the first of three</p><p>terms as mayor of New York City. Koch is credited with bringing fiscal  stability to the insolvent city and with instituting merit selection of city  judges. His brash forthrightness made him an entertaining and popular  figure, but his demeanour and his rhetoric increasingly came to be seen  as unkind and divisive and eventually resulted in his defeat. He later  became a columnist and talk-show host.</p><p>Koch \'kok,\ English Vkok\, (Heinrich Hermann) Robert (b. Dec.  11, 1843, Clausthal, Hannover�d. May 27, 1910, Baden-Baden, Ger.)  German physician. As the first to isolate the anthrax bacillus, observe its  life cycle, and develop a preventive inoculation for it, he was the first to  prove a causal relationship between a bacillus and a disease. He perfected  pure-culture techniques, based on Louis Pasteur�s concept. He isolated the  tuberculosis organism and established its role in the disease (1882). In 1883  he discovered the causal organism for cholera and how it is transmitted  and also developed a vaccination for rinderpest. Koch�s postulates remain  fundamental to pathology: the organism should always be found in sick  animals and never in healthy ones; it must be grown in pure culture; the  cultured organism must make a healthy animal sick; and it must be reiso�  lated from the newly sick animal and recultured and still be the same.

He was the first surgeon to remove  the thyroid gland to treat goitre (1876). He later found that total removal  could cause a state resembling cretinism, but that leaving part of the gland  in place made this temporary. He introduced a surgical method for reduc�  ing shoulder dislocations, as well as many new surgical techniques, instru�  ments, and appliances. A type of forceps and a gallbladder surgery incision  named for him are still used. He adopted Joseph Lister�s principles of com�  plete asepsis in surgery.

With Bela Bartok, a lifelong friend, he compiled the  important Hungarian Folk Songs (1906), and he continued to make field  recordings until World War I made it impossible. He came to international  attention with his Psalmus hungaricus (1923) and the opera Hary Janos  (1926). Kodaly created an individual style that was derived from Hun�  garian folk music, contemporary French music, and the religious music  of the Italian Renaissance. He devoted much of his energy to developing  a school music curriculum that would develop children�s musicality, and  the �Kodaly method� remains in wide use.</p><p>Kodiak Island Island (pop., 2000: 13,913), Alaska, U.S. Lying in the  Gulf of Alaska, it is 100 mi (160 km) long and 10-60 mi (16-96 km)  wide and has an area of 3,588 sq mi (9,293 sq km). The Kodiak National  Wildlife Refuge covers 75% of the island and is the habitat of the Kodiak  bear. Discovered in 1763 by a Russian fur trader, the island, known as  Kikhtak, became the site in 1784 of the first Russian colony in America.  Russian control ended in 1867; the island was renamed Kodiak in 1901.

April 3, 1930, Ludwigshafen am Rhein, Ger.)  Chancellor of West Germany (1982-90) and of reunified Germany (1990-  98). After earning a doctorate at the University of Heidelberg, he was  elected to the Rhineland-Palatinate legislature and became the state�s min�  ister president (1969). In 1973 he was elected chair of the Christian Demo�  cratic Union, and in 1982 he became Germany�s chancellor. Kohl�s  centrist policies included modest cuts in government spending and strong  support for West German commitments to NATO. After the fall of the  Berlin Wall in 1989, Kohl concluded a treaty with East Germany that uni�  fied the two countries� economic systems. Absorption of the moribund  East German economy proved difficult, and Kohl�s government had to  increase taxes and cut government spending after unification. In 1998 his  coalition government with the Free Democratic Party was defeated by the  Social Democrats under Gerhard Schroder. Revelations of serious finan�  cial irregularities during Kohl�s chancellorship soon emerged, tainting his  reputation and weakening his party.</p><p>Kohler, Kaufmann (b.

He was brought  up in Orthodox Judaism but soon came under the influence of Reform  leader Abraham Geiger. His early writings approached biblical texts criti�  cally and led to his exclusion from the German rabbinate. He emigrated  to the U.S. in 1869 and served Reform congregations in Detroit, Chicago,  and New York City. In 1885 he was the driving force in formulating the  Pittsburgh Platform. He served as president of Hebrew Union College in  Cincinnati 1903-21. His chief work was Jewish Theology (1918).</p><p>Kohler Vkoe-brV Wolfgang (b.

His studies of problem solving by chimpanzees ( The Mentality  of Apes, 1917), in which he examined learning and perception as struc�  tured wholes, led to a radical revision of existing theory, and Kohler  became a key figure in the development of Gestalt psychology. He con�  tinued his research during the 1920s and early �30s at the University of  Berlin, publishing Gestalt Psychology (1929, rev. 1947), but emigrated  from Germany to the U.S. after the Nazi takeover and taught at Swarth-  more College (1935-55).

The classical example of a koine (as well as the  source of the term) is Hellenistic Greek, which developed from Attic Greek  through replacement of the most distinctively Attic features by features  of Ionic or other dialects. A koine may serve as a lingua franca and often  forms the basis of a new standard language.</p><p>Koizumi Jun'ichird (b.

He ran unsuccessfully for his father�s seat after the latter�s death  in 1969 but was elected in 1971. He held ministerial posts in 1988-89,  1992-93, and 1996-98. After unsuccessful bids for the presidency of the  Liberal-Democratic Party in 1995 and 1998, he won in April 2001 and was  soon confirmed as prime minister.

March 1, 1886, Pochlam,  Austria�d. Feb. 22,1980, Villeneuve, Switz.) Austrian painter and writer.  He studied and taught at the Vienna School of Arts and Crafts but was  dissatisfied because the school omitted study of the human figure, his pri�  mary artistic interest. His early paintings were rendered in delicate, agi�  tated lines and relatively naturalistic colours. After c. 1912 he became a  leading exponent of Expressionism; his portraits came to be painted with  increasingly broader strokes of more varied colour and heavier outlines.  While recovering from a wound received in World War I, he wrote, pro�  duced, and staged three plays; his Orpheus and Eurydice (1918) became  an opera by Ernst Krenek (1926). The landscapes he produced during 10  years of teaching and travel mark the second peak of his career. Shortly  before World War II he fled to London, where his paintings became  increasingly political and antifascist. He continued his political art after  moving to Switzerland in 1953.</p><p>Kol Nidre Vk61-'ni-dra\ Prayer sung in Jewish synagogues at the start  of services on the eve of Yom Kippur.

The British established a trading centre at the  site in 1690, which grew and became the seat of the Bengal presidency  in 1707. It was captured by the nawab of Bengal, who in 1756 impris�  oned the British there (in a prison that was later known as the Black Hole);  the city was retaken by the British under Robert Clive. It was an extremely  busy 19th-century commercial centre, but it began to decline with the  removal of the colonial capital to Delhi in 1912. The decline continued  when Bengal was partitioned between India and Pakistan in 1947 and  when Bangladesh was created in 1971. The flood of refugees from those  political upheavals boosted the city�s population but also significantly  added to its widespread poverty. Despite its problems, Kolkata remains  the dominant urban area of eastern India and a major educational and cul�  tural centre.</p><p>Kollontay \,ka-l3n-'tl\, Aleksandra (Mikhaylovna) orig.

She gained firsthand knowledge of the  miserable conditions of the urban poor when her physician husband  opened a clinic in Berlin. She became the last great practitioner of Ger�  man Expressionism and an outstanding artist of social protest. Two early  series of prints, Weavers� Revolt (1895-98) and Peasants� War (1902-</p><p>08), portray the plight of the  oppressed with the powerfully sim�  plified, boldly accentuated forms that  became her trademark.

In the 1920s he helped develop the first Soviet Five-Year Plan, for  which he analyzed factors that would stimulate Soviet economic growth.  After criticizing Joseph Stalin�s plan for the total collectivization of agri�  culture, he was dismissed from his post as director of the Institute for the  Study of Business Activity in 1928. He was arrested in 1930 and sen�  tenced to prison; his sentence was reviewed in 1938, and he received the  death penalty, which was likely carried out the same year.

Carved from marble and originally painted, the kore is a  draped female figure standing erect with feet together or one foot slightly  advanced. One arm is often extended, holding an offering; the other is  lowered, usually clasping a fold of drapery. As in all Greek art, the kore  evolved from a highly stylized form to a more naturalistic one. Its pro�  totypes are found in Egyptian and Mesopotamian art.</p><p>Korea Korean Chosdn \'cho-son\ or Taehan Former kingdom, a  peninsula (Korean peninsula) on the eastern coast of Asia. In 1948 it was  partitioned into two republics, North Korea and South Korea. According  to tradition, the ancient kingdom of Choson was established in the north�  ern part of the peninsula probably by peoples from northern China in the  3rd millennium bc. Conquered by China in 108 bc, it later developed into  the Three Kingdoms of Silla, Koguryo, and Paekche. Silla conquered the  other two in the 7th century ad and ruled until 936, when the Paekche  dynasty became prominent. Invaded by the Mongols in 1231, the king�  dom of Choson, with its capital at Seoul, was ruled by the Choson (Yi)  dynasty (see Yi Song-gye) from 1392 to 1910. From c. 1636 it shut out  foreign contacts but was forced after 1873 to open ports to Japan. Rivalry  over Korea brought on the Russo-Japanese War (1904-05), after which  Korea became a Japanese protectorate. Formally annexed to Japan in  1910, it was freed from Japanese control in 1945 at the end of World War  II. After the war it was divided into two zones of occupation, Soviet in  the north and U.S. in the south; the two republics were established in 1948.

North Korea�s land area largely consists of moun�  tain ranges and uplands; its highest peak is the volcanic Mount Paektu  (9,022 ft [2,750 m]). North Korea has a centrally planned economy based  on heavy industry (iron and steel, machinery, chemicals, and textiles) and  agriculture. Cooperative farms raise crops such as rice, corn, barley, and  vegetables. The country is rich in mineral resources, including coal, iron  ore, and magnesite. It is a republic with one legislature; the head of state  and government is the chairman of the National Defense Commission.  For early history, see Korea. After the Japanese were defeated in World  War II, the Soviet Union occupied Korea north of latitude 38� N; there  the Democratic People�s Republic of Korea was established as a com�  munist state in 1948. Seeking to unify the peninsula by force, it launched  an invasion of South Korea in 1950, initiating the Korean War. UN troops  intervened on the side of South Korea, and Chinese soldiers reinforced  the North Korean army in the war, which ended with an armistice in 1953.  Led by Kim Il-sung, North Korea became one of the most harshly regi�  mented societies in the world, with a state-owned economy that failed to  produce adequate supplies of food and consumer goods for its citizens.  Under his son and successor, Kim Jong II, the country endured periods of  severe food shortages from the late 1990s that caused widespread fam�  ine. Hopes that North Korea was seeking to end its long isolation�  notably through meetings between Kim and the leaders of South Korea  (2000) and Japan (2002)�have been tempered by concerns over its  nuclear weapons program.</p><p>Korea, South officially Republic of Korea Country, East Asia,  occupying the southern half of the Korean peninsula.

For  early history, see Korea. The Republic of  Korea was established in 1948 in the por�  tion of the Korean peninsula south of latitude 38� N, which had been  occupied by the U.S. after World War II. In 1950 North Korean troops  invaded South Korea, precipitating the Korean War. UN forces intervened  on the side of South Korea, while Chinese troops backed North Korea in  the war, which ended with an armistice in 1953. The devastated country  was rebuilt with U.S. aid, and South Korea prospered in the postwar era,  developing a strong export-oriented economy. It experienced an economic  downturn beginning in the mid-1990s that affected many countries in the  area. Efforts at reconciliation between North and South Korea, including  the first-ever summit between their leaders (2000) and reunions between  families from both countries, were accompanied by periods of continu�  ing tension.</p><p>Korea Strait Channel between South Korea and southwestern Japan.  Connecting the East China Sea with the Sea of Japan (East Sea), it is 120  mi (195 km) wide and is divided by the Tsushima islands at its centre.  Its passage to the east is known as Tsushima Strait, site of the Battle of  Tsushima (1905); to the west it is called the Western Channel.</p><p>Korean language Official language of North Korea and South Korea,  spoken by more than 75 million people, including substantial communi�  ties of ethnic Koreans living elsewhere. Korean is not closely related to  any other language, though a distant genetic kinship to Japanese is now  thought probable by some scholars, and an even more remote relationship  to the Altaic languages is possible. Korean was written with Chinese char�  acters to stand in various ways for Korean meanings and sounds as early  as the 12th century, though substantial documentation is not evident until  the invention of a unique phonetic script for it in 1443. This script, now  called Hangul, represents syllables by arranging simple symbols for each  phoneme into a square form like that of a Chinese character. Grammati�  cally, Korean has a basic subject-object-verb word order and places modi�  fiers before the elements they modify.</p><p>Korean War (1950-53) Conflict arising after the post-World War II  division of Korea, at latitude 38� N, into North Korea and South Korea.  At the end of World War II, Soviet forces accepted the surrender of Japa�  nese forces north of that line, as U.S. forces accepted Japanese surrender  south of it. Negotiations failed to reunify the two halves, the northern half  being a Soviet client state and the southern half being backed by the U.S.  In 1950 North Korea invaded South Korea, and U.S. Pres. Harry Truman  ordered troops to assist South Korea. The UN Security Council, minus  the absent Soviet delegate, passed a resolution calling for the assistance</p><p>of all UN members in halting the invasion. At first North Korean troops  drove the South Korean and U.S. forces down to the southern tip of the  Korean peninsula, but a brilliant amphibious landing at Inch�on, con�  ceived by Gen. Douglas MacArthur, turned the tide in favour of the UN  troops, who advanced near the border of North Korea and China. The  Chinese then entered the war and drove the UN forces back south; the  front line stabilized at the 38th parallel. MacArthur insisted on voicing  his objections to U.S. war aims in a public manner and was relieved of  his command by Truman. U.S. Pres. Dwight D. Eisenhower participated in  the conclusion of an armistice that accepted the front line as the de facto  boundary between the two Koreas. The war resulted in the deaths of  approximately 2,000,000 Koreans, 600,000 Chinese, 37,000 Americans,  and 3,000 Turks, Britons, and other nationals in the UN forces.</p><p>Kornberg, Arthur (b. March 3, 1918, Brooklyn, N.Y., U.S.) U.S. bio�  chemist and physician. He studied at the University of Rochester. In 1959  he joined the faculty at Stanford University. While studying how living  organisms manufacture nucleotides, his research led him to the problem of  how nucleotides are strung together to form DNA molecules. Adding radio�  active nucleotides to an enzyme mixture prepared from cultures of E. cou,  he found evidence of a reaction catalyzed by the enzyme that adds nucle�  otides to a preexisting DNA chain. He was the first to accomplish the cell-  free synthesis of DNA. He shared a 1959 Nobel Prize with Severo Ochoa.</p><p>Korngold, Erich Wolfgang (b. May 29, 1897, Briinn, Austria-  Hungary�d.

He solidified his  reputation with his operatic masterpiece, Die tote Stadt (1920). In 1934  he moved to Hollywood, and he became best known for his film scores,  his broadly Romantic style proving very suitable to swashbuckling sto�  ries such as Anthony Adverse (1936, Academy Award) and The Adven�  tures of Robin Hood (1938, Academy Award), as well as 17 others.

After the Russian Revolution  of 1917, he was appointed army commander in chief by Aleksandr Ker�  ensky. Conflicts developed because of their opposing views on politics and  the role of the army, and, when Kornilov sent troops toward Petrograd,  Kerensky interpreted the move as an attempted coup and dismissed him.

During this period Korea began to form a distinctively  Korean cultural tradition. The dynasty was formed by Gen. Wang Kon of  Later Koguryo, who defeated the kingdoms of Silla and of Later Paekche  to create a unified Korean peninsula in 936. In the late 10th century, a  centralized bureaucratic system replaced the old aristocratic tribal system.  The kingdom saw a flowering of the arts, particularly ceramics (Koryo  celadon), and Buddhism and Confucianism were influential. In the 13th  century Koryo endured a series of Mongol invasions, and in 1392 Yl  Song-gye overthrew the shaky dynasty and founded the Choson dynasty.</p><p>Kosala Vko-S3-l3\ Ancient kingdom, northern India.

He helped build fortifications in Philadelphia, Pa., and at  West Point, N.Y. As chief of engineers, he twice rescued the army of Gen.  Nathanael Greene by directing river crossings. He also directed the block�  ade of Charleston, S.C. At the war�s end he was awarded U.S. citizenship  and made a brigadier general. He returned to Poland in 1784 and became a  major general in the Polish army. In 1794 he led a rebellion against occu�  pying Russian and Prussian forces, during which he defended Warsaw for  two months, directing residents to build earthworks. He was jailed in Rus�  sia from 1794 to 1796, returned to the U.S. in 1797, and then left for France,  where he continued efforts to secure Polish independence.</p><p>kosher See kashruth</p><p>Kosi River \'ko-se\ River, Nepal and northern India.

He  claimed that his horrific experiences as a Jew in World War II Poland and  Russia caused him to be mute for much of his childhood. He studied politi�  cal science and became a professor of sociology before immigrating to the  U.S. in 1957. His novel The Painted Bird (1965) is a graphic, surrealistic  tale of the horrors surrounding the war. Other successful novels were Steps  (1968) and the satiric fable Being There (1970; film, 1979).

It occu�  pies an area of 4,203 sq mi (10,887 sq km); its administrative capital is  Pristina. Before 1999, ethnic Albanians, most of whom are Muslims, made  up about four-fifths of its population, with Serbs (mostly Christian)  accounting for the bulk of the remainder. Kosovo was an autonomous  region until 1989, when Serbia took control of Kosovo�s administration,</p><p>prompting protests from the region�s Albanian population, which in 1990  voted to secede from Yugoslavia. Serbia responded by tightening its con�  trol of Kosovo, which led to the Kosovo conflict. From 1999 the region  was administered by the UN.</p><p>Kosovo Vko-so-.voV Battle of Either of two battles fought in the Ser�  bian province of Kosovo. The first (June 13, 1389), between the Serbs  under Prince Lazar and the Ottoman Empire led by Sultan Murad I,  ended�despite Murad�s death�in the defeat of Serbia and the encircle�  ment of the crumbling Byzantine Empire by Ottoman armies. The battle,  which led to three centuries of Serbian vassalage, has remained a central  event in Serbian history. In the second battle (Oct. 17-20, 1448), between  the Ottomans led by Murad II and a Hungarian-Walachian coalition under  Hunyadi Janos, halted the last major effort by Christian Crusaders to free  the Balkans from Ottoman rule.</p><p>Kosovo conflict (1998-99) Ethnic war in Kosovo, Yugoslavia. In 1989  the Serbian president, Slobodan Milosevic, abrogated the constitutional  autonomy of Kosovo. He and the minority of Serbs in Kosovo had long  bristled at the fact that Muslim Albanians were in demographic control  of an area considered sacred to Serbs (Kosovo was the seat of the Ser�  bian Orthodox church, the inspiration for Serbian epic poetry, and the site  of the Turkish defeat of the Serbs in 1389 and Serbian victory over the  Turks in 1912). In response, the Albanian Kosovars began a campaign of  nonviolent resistance. Growing tensions led in 1998 to armed clashes  between Serbs and the Kosovo Liberation Army (KLA), which had begun  killing Serbian police and politicians. The Contact Group (U.S., Britain,  Germany, France, Italy, and Russia) demanded a cease-fire, the uncondi�  tional withdrawal of Serbian forces, the return of refugees, and unlimited  access for international monitors. Although Milosevic agreed to meet  most of the demands, he failed to implement them. The KLA regrouped  and rearmed during the cease-fire and renewed its offensive. The Serbs  responded with a ruthless counteroffensive, inducing the UN Security  Council to condemn the Serbs� excessive use of force, including ethnic  cleansing (killing and expulsion), and to impose an arms embargo, but the  violence continued. After diplomatic negotiations at Rambouillet, France,  broke down, Serbia renewed its assault, and NATO responded with an  11-week bombing campaign that extended to Belgrade, accidentally  destroyed the Chinese embassy, and significantly damaged Serbia�s infra�  structure. The bombing was halted after NATO and Yugoslavia signed an  accord in June 1999 outlining Serbian troop withdrawal and the return of  nearly 1,000,000 ethnic Albanian refugees as well as 500,000 displaced  within the province; there were sporadic reprisals again Serbs who  remained in Kosovo.</p><p>Kossuth Vk6-,shut,\ English Yka-.siithV Lajos (b.

Intrigued by Arnold Schoenberg�s 12-tone method (see seri-  alism), he devised his own version�which involved �rotation� of the set�s  order�for the opera Karl V (1933), the first 12-tone opera. He immigrated  to the U.S. in 1937 and taught at several institutions, but his large body  of work remained more highly esteemed in Europe.</p><p>Kresge \'krez-ge\, S(ebastian) S(pering) (b. July 31, 1867, Bald  Mount, Pa., U.S.�d. Oct. 18, 1966, East Stroudsburg, Pa.) U.S. merchant.  He worked as a traveling salesman before becoming a partner in 5-and-  10-cent stores in Memphis, Tenn., and Detroit, Mich., in 1897. He opened  several others in major Midwest cities, founding the S.S. Kresge Co. in  1907 (incorporated 1912). After World War II the firm expanded into large  discount stores in the U.S., Puerto Rico, and Canada, which eventually  numbered nearly 1,000. Kresge established a major charitable foundation  in 1924. His retail empire became the foundation of the Kmart Corp.</p><p>Kretschmer Vkrech-moA, Ernst (b. Oct. 8, 1888, Wiistenrot, Ger.�d.  Feb. 8, 1964, Tubingen, W.Ger.) German psychiatrist. In his best-known  work, Physique and Character (1921), he attempted to correlate body  build and physical constitution with character and mental illness, identi�  fying three physical types�the pyknic (rotund), the athletic (muscular),  and the asthenic (tall and thin)�and claiming that different psychiatric  disorders were associated with each. His system was later adapted by the  American psychologist William H. Sheldon (1899-1977), who renamed  the types endomorph, mesomorph, and ectomorph and focused on their  associated personality traits. Both theorists� work entered into popular  culture and generated further research.</p><p>Kriemhild \'krem-,hilt\ or Gudrun In the Nibelungenued, the gentle  princess courted by Siegfried.

The name also refers to the  genus Euphausia within the suborder and sometimes to a single species,  E. superba. The described species, numbering more than 80, range in size  from about 0.25 to 2 in. (8-60 mm). Most have bioluminescent organs on  the lower side, making them visible at night. They are an important source  of food for various fishes, birds, and whales, particularly blue and fin  whales. Krill may occur in vast swarms at the ocean surface, where they  feed at night, and at depths greater than about 6,000 ft (2,000 m). Because  of their vast numbers and nutritive qualities (they are an especially rich  source of vitamin A), krill have been regarded as a potential source of  food for humans.</p><p>Krishna One of the most widely venerated Hindu gods, worshiped as  the eighth incarnation of Vishnu and as the supreme deity. Many BUishna  legends are drawn from the Mahabharata and the Puranas. His earliest  appearance is in the Mahabharata as the divine charioteer of Arjuna,  whom Krishna convinces that the war Arjuna is about to fight is just (see  Bhagavadgita). In later works Krishna was a slayer of demons, a secret  lover of all devotees, and a devoted son and father. He also lifted the  sacred hill of Govardhana on one finger to protect his devotees from  Indra�s wrath. In art Krishna is often depicted with blue-black skin, wear�  ing a loincloth and a crown of peacock feathers. As a divine lover, he is  shown playing the flute, surrounded by adoring females.</p><p>Krishna River formerly Kistna River River, southern India.

He was educated in theosophy by Annie Besant, who pro�  claimed him the coming �World Teacher,� a messiah-like figure who  would bring about world enlightenment. He became a teacher and writer,  and from the 1920s he spent much time in the U.S. and Europe. He broke  with formal theosophy in 1929 and renounced any claims to being a World  Teacher, but he continued to be a popular lecturer. His desire, he said, was  to set people free, a goal that could only be achieved through unflinching  self-awareness. He established a number of Krishnamurti foundations in  the U.S., Britain, and India to further his aims. His books include The  Songs of Life (1931) and Commentaries on Living (1956-60).</p><p>Kristallnacht \kres-'tal-,nakt\ or Crystal Night or Night of Bro�  ken Glass Night of violence against Jews, carried out by members of  the German Nazi Party on Nov. 9-10, 1938, so called because of the bro�  ken glass left in its aftermath. The violence, instigated by Joseph Goeb-  bels, left 91 Jews dead and hundreds seriously injured. About 7,500 Jewish  businesses were gutted and some 1,000 synagogues burned or damaged.  The Gestapo arrested 30,000 Jewish males, offering to release them only  if they emigrated and surrendered their wealth. The incident marked a  major escalation in the Nazi program of Jewish persecution, foreshadow�  ing the Holocaust.</p><p>Kristeva \kre-sta-'va,\ English \kri-'sta-V3\, Julia (b.

He was working as a blender salesman when he discovered  a restaurant in San Bernardino, Calif., owned by Maurice and Richard  McDonald, who used an assembly-line format to prepare and sell a large  volume of hamburgers, french fries, and milk shakes. Beginning in 1955  Kroc opened his first McDonald�s drive-in restaurant in Des Plaines, Ill.,  paying the brothers a percentage of the receipts. He soon began selling</p><p>franchises for new restaurants, and  he instituted a training program for  owner-managers that emphasized  automation and standardization.

Trained  under Franz Boas (Ph.D., 1901), he  later taught at the University of Cali�  fornia at Berkeley. Kroeber�s career  nearly coincided with the emergence  of academic, professionalized anthro�  pology in the U.S. and contributed  significantly to its development. He  made valuable contributions to  American Indian ethnology, New  World archaeology, and the study of  linguistics, folklore, kinship, and culture. His most influential books are  considered to be Anthropology (1923) and The Nature of Culture (1952).  His daughter, Ursula K. Le Guin (b. 1929), was a noted science fiction and  fantasy writer.</p><p>Kroemer, Herbert (b. Aug. 25, 1928, Weimar, Ger.) German physi�  cist. He received a Ph.D. (1952) from Georg August University in Got�  tingen and later moved to the U.S., where he taught at several institutions.  In 1957 he carried out theoretical calculations showing that a heterostruc�  ture transistor, which is made from several materials, would be superior  to a conventional transistor, which is made from only one kind of mate�  rial. His theory was later confirmed and led to the development of numer�  ous electronic components that had a significant influence on  communications technology and computers. He shared the 2000 Nobel  Prize for Physics with Zhores Alferov and Jack S. Kilby.</p><p>Kronos See Cronus</p><p>Kronshtadt \'kron-,shtat\ Rebellion (1921) Internal uprising against  Soviet rule in Russia after the Russian Civil War, conducted by sailors from  the Kronshtadt naval base. The sailors had supported the Bolsheviks in the  Russian Revolution of 1917, but disillusionment with the government and  inadequate food supplies after the civil war led them to demand economic  and labour reform and political freedoms. The rebels were crushed by a  force led by Leon Trotsky and Mikhayl Tukhachevsky, and the survivors were  shot or imprisoned. By dramatically demonstrating popular dissatisfac�  tion with communist policies, the rebellion, along with several other major  internal uprisings, led to the adoption of the New Economic Policy.</p><p>Kronstadt See Brasov</p><p>Kropotkin Vkro-'pot-ksnV Peter  (Alekseyevich) (b.

South African soldier and statesman, noted as the builder of the  Afrikaner nation. As a boy of 10, Kruger took part in the Great Trek and  was impressed by the ability of the Boers to defend themselves against  hostile African peoples and to establish an orderly government. When the  British annexed the Transvaal in 1877, Kuger became the recognized  champion of his people in the struggle to regain independence. After  leading a series of armed attacks, he succeeded in obtaining limited inde�  pendence and was elected president of the restored republic (1883-1902).  In 1895 he fended off an attempt by Cecil Rhodes and Leander Starr Jame�  son to end Boer control of the republic. His age prevented his participa�  tion in the South African War and he retreated to the Netherlands; he died  in Switzerland and was buried (December 1904) in Pretoria, S.Af.</p><p>Kruger National Park National park, South Africa. Located in the  northeastern part of the country on the Mozambique border, it was cre�  ated as a game sanctuary in 1898 and in 1926 became a national park  named for Paul Kuger. It covers an area of 7,523 sq mi (19,485 sq km)  and contains six rivers. It has a wide variety of wildlife, including  elephants, lions, and cheetahs. In December 2002 it became part of Afri�  ca�s largest game park when Kuger National Park was joined with Lim�  popo National Park in Mozambique and Gonarezhou National Park in  Zimbabwe to form the Great Limpopo Transfrontier Park.</p><p>Krupa, Gene (b.

Krupa had worked with Eddie Condon (1905-73) in Chicago before mov�  ing to New York City in 1929 and joining Benny Goodman�s big band in  1935. He quickly became the best-known drummer of his day, famous for  the showmanship and technique displayed in extended drum solos such  as that in �Sing, Sing, Sing.� He formed his own successful band in 1938,  featuring trumpeter Roy Eldridge and singer Anita O�Day (b. 1919). Ku-  pa�s energetic playing became the model for many drummers of the swing  era.</p><p>Krupp Vkrup\ family German steel-manufacturing dynasty. Friedrich  Kupp (1787-1826) founded a steel factory in Essen in 1811. On his death  his son Alfred (1812-1887) took full charge of the faltering concern at  age 14. He made a fortune supplying steel to the railways and manufac�  turing cannons; the performance of Kupp guns in the Franco-Prussian  War of 1870-71 led to the firm�s being called �the Arsenal of the Reich.�  At Alfred�s death he had armed 46 nations. The rise of the German navy  and the need for armour plates further enriched the company under his  son Friedrich Alfred (1854-1902). By the time Friedrich Alfred�s elder  daughter, Bertha (1886-1957), inherited control of the firm, it employed  more than 40,000 people. Her husband, Gustav von Bohlen (1870-1950),  affixed Kupp to the beginning of his name; an ardent Nazi, he ran the  Kupp empire until 1943, when he was succeeded by their son Alfried  Kupp (1907-1967). The Kupp works used slave labour during World  War II and were a major part of the Nazi war machine; Alfried was later  convicted of war crimes at Niimberg. An Allied order to break up the  company in 1953 languished for lack of a buyer, and Alfried eventually  restored the Kupp fortune.

In ancient times before the caste system was completely  defined, they were considered first in rank, placed higher than the Brah�  mans, or priestly class. The legend that they were degraded by an incar�  nation of Vishnu as a punishment for their tyranny may reflect a historical  struggle for supremacy between priests and rulers. In modem times the  Kshatriya varna includes members from a variety of castes, united by their  status in government or the military or their land ownership.</p><p>Ksitigarbha Vkshi-ti-'gor-boV Buddhist bodhisattva widely revered in  China and Japan. Known in India from the 4th century bc, he became  popular in China as Dicang and in Japan as Jizo. He is the patron of the  oppressed or dying, and he seeks to save the souls of the dead condemned  to hell. In China he is the overlord of hell, and in Japan he is known for  his kindness to the departed, particularly to dead children. Usually  depicted as a monk with a nimbus around his shaved head, he carries a  staff to force open the gates of hell and a flaming pearl to light up the  darkness.</p><p>Ku Klux Klan (KKK) Either of two racist terrorist organizations in the  U.S. The first was organized by veterans of the Confederate army, first  as a social club and then as a secret means of resisting Reconstruction and  restoring white domination over newly enfranchised blacks. Dressed in  white robes and sheets, Klansmen whipped and killed freedmen and their  white supporters in nighttime raids (see lynching). It had largely accom�  plished its goals by the 1870s before gradually fading away. The second  KKK arose in 1915, partly out of nostalgia for the Old South and partly  out of fear of the rise of communism in Russia and the changing ethnic  character of U.S. society. It counted Catholics, Jews, foreigners, and  labour unions among its enemies. Its membership peaked in the 1920s at  more than four million, but during the Great Depression the organization  gradually declined. It became active again during the civil rights movement  of the 1960s, attacking blacks and white civil rights workers with bomb�  ings, whippings, and shootings. By the end of the 20th century, growing  racial tolerance had reduced its numbers to a few thousand.</p><p>Kuala Lumpur \'kwa-lo-Tum- l pur\ City (pop., 2000 prelim.:  1,297,526), capital of Malaysia.

As presi�  dent he promoted rapid development of the hydroelectric, steel, and other  heavy industries and built 11,000 mi (18,000 km) of roads. He moved the  government from Rio de Janeiro to Brasilia, 600 mi (1,000 km) inland, to  accelerate the settlement of Brazil�s vast interior. One price of his ambi�  tious development was rapid and persistent inflation, exacerbated by the  need to spend large sums to aid the drought-stricken northeastern region.  The military government that took power in 1964 forced him into exile  (1965-67). On returning to Brazil, he became a banker.</p><p>Kublai Khan Vkii-bb-'kanV (b. 1215�d. 1294) Grandson of Genghis  Khan who conquered China and  established the Yuan, or Mongol,  dynasty. When Kublai was in his  30s, his brother, the emperor  Mongke, gave him the task of con�  quering and administering Song-  dynasty China. Recognizing the  superiority of Chinese thought, he  gathered around himself Confucian  advisers who convinced him of the  importance of clemency toward the  conquered. In subduing China and  establishing himself there, he alien�  ated other Mongol princes; his claim  to the title of khan was also disputed.</p><p>Though he could no longer control  the steppe aristocracy effectively, he  succeeded in reunifying China, sub�  duing first the north and then the  south by 1279. To restore China�s  prestige, Kublai engaged in wars on its periphery with Myanmar, Java,  Japan, and the nations of eastern Southeast Asia, suffering some disas�  trous defeats. At home, he set up a four-tiered society, with the Mongols  and other Central Asian peoples forming the top two tiers, the inhabitants  of northern China ranking next, and those of southern China on the bot�  tom. Posts of importance were allotted to foreigners, including Marco  Polo. Kublai repaired the Grand Canal and public granaries and made  Buddhism the state religion. Although his reign was one of great prosper�  ity, his politics were pursued less successfully by his followers.</p><p>Kubrick \'kyu-brik\, Stanley (b. July 26, 1928, New York, N.Y.,  U.S.�d.

He directed two documentary films before  directing his first feature film, Fear and Desire (1953). He won fame with  Paths of Glory (1957), Spartacus (1960), Lolita (1962), Dr. Strangelove  (1964), and the internationally acclaimed 2001: A Space Odyssey (1968),  which earned an Academy Award for special visual effects. His later mov�  ies include A Clockwork Orange (1971), Barry Lyndon (1975), The Shin�  ing (1980), Full Metal Jacket (1987), and Eyes Wide Shut (1999). His  films are characterized by a cool visual style, meticulous attention to  detail, and a detached, often ironic pessimism.</p><p>Kiicuk Kaynarca, Treaty of (1774) Pact signed after the Russo-  Turkish War of 1768-74, in Kii^iik Kaynarca (now Kaynardzha), Bulg.,  ending undisputed Ottoman control of the Black Sea.

Transplanted from its native China and Japan to North America  in the 1870s as an attractive ornamental that could be planted on steep  soil banks to prevent erosion, kudzu has become a rampant weed in much  of the southeastern U.S, where it readily spreads to form great canopies  over trees, shrubs, and exposed soil. Roots survive even northern winters,  and the hairy vine grows to a length of 60 ft (18 m) in one season. It has  large leaves, late-blooming reddish-purple flowers, and flat, hairy seed-  pods. In its native range kudzu is grown for its edible, starchy roots and  for a fiber made from its stems.

In his highly  influential work The Structure of Scientific Revolutions (1962), he ques�  tioned the previously accepted view of scientific progress as a gradual  accumulation of knowledge based on universally valid experimental  methods and results, claiming that progress was often achieved by far-  reaching �paradigm shifts.� His other works include The Copernican  Revolution (1957), The Essential Tension (1977), and Black-Body Theory  and the Quantum Discontinuity (1978).</p><p>Kuiper Vkl-p9r\ belt or Edgeworth-Kuiper belt Disk-shaped belt  of billions of small, icy bodies orbiting the Sun beyond the orbit of Nep�  tune, mostly at distances 30-50 times Earth�s distance from the Sun. Ger�  ard Peter Kuiper (1905-73) proposed the existence of this large flattened  distribution of objects in 1951 in connection with his theory of the origin  of the solar system (see solar nebula). Kenneth Edgeworth (1880-1972)  independently had made similar proposals in 1943 and 1949. Whether the  belt extends thinly as far as the Oort cloud is not known. Gravitational  disturbances by Neptune of objects in the belt are thought to be the ori�  gin of most short-period comets. The first Kuiper belt object was discov�  ered in 1992, although the orbit, icy composition, and diminutive size of  Pluto appear to qualify this body, traditionally considered a planet, as a  giant Kuiper belt object.</p><p>Kukai Yku-.kA or Kobo Daishi (b.

Born into an aristocratic family, Kukai  was given a Confucian education but soon converted to Buddhism. After  studying in China (804-806) with Huiguo (746-805), he returned home  to spread his doctrines, which emphasized magic formulas, ceremonials,  and services for the dead. In 816 he built a temple on Mount Koya, and  he helped to establish the Shingon sect as one of the most popular forms  of Japanese Buddhism.

Bismarck, a staunch Protestant, doubted the loyalty of  Catholics in his new German Empire and became concerned by the Vat�  ican Council�s 1870 proclamation on papal infallibility. In 1872 the state  dissolved the Jesuit order in Germany. The May, or Falk, Laws of 1873  (applying only to Prussia) limited church powers, and in 1875 the state  mandated civil marriage services. Bismarck retreated in the face of strong  Catholic resistance, especially by the Center Party.

Except for Al-Jahra� oasis,  at the western end of Kuwait Bay, and a few fertile patches in the south�  eastern and coastal areas, it is largely desert; annual precipitation totals  1-7 in. (25-180 mm). Kuwait has almost no arable land, but there is a  small amount of pastureland for livestock. Its extensive petroleum and  natural gas deposits are the basis of its economy. Its estimated reserves  of petroleum represent roughly one-tenth of global reserves, ranking  Kuwait third, behind Iraq and Saudi Arabia. It is a constitutional monar�  chy with one legislative body; the head of state and government is the  emir, assisted by the prime minister. Traces of civilization on Faylakah,  an island in Kuwait Bay, date to the 3rd millennium bc. These flourished  until c. 1200 bc, when they disappeared from the historical record.

It was created in 1966 by Maulana Karenga, a black-studies  professor at California State University at Long Beach, as a nonreligious  celebration of family and community. The name was taken from the Swa�  hili phrase matunda ya kwanzaa (�first fruits�). Each day is dedicated to  one of seven principles: unity, self-determination, collective responsibil�  ity, cooperative economics, purpose, creativity, and faith. Each evening,  family members gather to light one of the candles in the kinara, a seven-  branched candelabra; often gifts are exchanged. On December 31 com�  munity members gather for a feast, the karamu. Kwanzaa is now observed  by more than 15 million people.</p><p>kwashiorkor X.kwa-she-'or-koiA Condition caused by severe protein  deficiency. It is common in tropical and subtropical regions in young chil�  dren weaned on a diet chiefly of starchy foods such as grains, cassava,  plantain, and sweet potato. It causes potbelly, edema, weakness, irritabil�  ity, dry skin with rash, reddish-orange hair discoloration, diarrhea, anemia,  and fat deposits in the liver. Mental development may be stunted. Adults  who had the disease in childhood may be at risk of diseases such as cir�  rhosis. Treatment is protein supplementation, often in the form of dried  skim milk. For long-term prevention, development of high-protein plant  mixtures based on local food preferences and availability is encouraged.  Nondietary causes include inadequate absorption of nutrients by the intes�  tines, chronic alcoholism, kidney disease, and trauma (e.g., infection,  bums) causing abnormal protein loss.</p><p>Kweichow See Guizhou  Kworra River See Niger River</p><p>kyanite Vkl-o-.nfiA or cyanite VsI-o-.nflA or disthene \'dis-,then\ Sili�  cate mineral, one of several phases in the aluminum silicate (Al 2 Si0 5 ) sys�  tem.

December  1594, London) English dramatist. With The Spanish Tragedie (1592), he  initiated the revenge tragedy, a favourite dramatic form in the Elizabethan  and Jacobean eras in which the main motivation was revenge. One of the  most popular plays of its time, it prepared the way for William Shake�  speare�s Hamlet and other plays. The only other play certainly by Kyd is  Cornelia (1594). He was arrested and tortured in 1593 after �atheistical�  documents were found in his room; he claimed the papers belonged to  Christopher Marlowe, with whom he had shared lodgings. His reputation  ruined, he died the next year at age 36.</p><p>Kydland, Finn E. (b. December 1943, Algard, near Stavanger, Nor.)  Norwegian economist. Kydland was educated at the Norwegian School  of Economics and Business Administration (B.S., 1968) and Carnegie  Mellon University in Pittsburgh, Pa. (Ph.D., 1973), where Edward C. Pres�  cott advised him on his doctorate. Kydland, working with Prescott, dem�  onstrated how a declared commitment to a low inflation rate by policy</p><p>makers might create expectations of low inflation and unemployments  rates. They also established the microeconomic foundation for business  cycle analyses, showing that technology changes or supply shocks, such  as oil price hikes, could be reflected in investment and relative price  movements and thereby create short-term fluctuations around the long�  term economic growth path. In 2004 Kydland shared the Nobel Prize for  Economics with Prescott.</p><p>Kynewulf See Cynewulf</p><p>Kyoga Lake Lake, south-central Uganda.

He explored the Ohio River region  (1669) and then worked with the count de Frontenac to extend French  influence. He helped establish Fort Frontenac on Lake Ontario, where as  seigneur he controlled the fur trade. He obtained authority from Louis  XIV to explore the western frontier of New France and build new forts.  He sailed down the Illinois River and with Henri de Tonty (16507-1704)  canoed down the Mississippi River to the Gulf of Mexico. There in 1682  La Salle claimed the entire Mississippi Basin for France, naming it Loui�  siana after Louis XIV. Back in France, he received authority to build a  fort at the mouth of the Mississippi. Beset by losses of men and ships, he  mistakenly landed at Matagorda Bay, Texas. After fruitless attempts to  locate the Mississippi, he was killed by mutineers.</p><p>La Sea la Opera house in Milan, Italy.

The name by extension  applies to a late Iron Age culture of  European Celts. La Tene culture  originated in the mid-5th century bc,  when the Celts came into contact  with Greeks and Etruscans. It passed  through several phases and regional  variations during the next 400 years,  as the Celts populated northern  Europe and the British Isles, and  ended in the mid-1st century bc,  when most of the Celts came under  Roman control. Objects of the early  period are characterized by orna�  mental S-shapes, spirals, and round  patterns. The middle period is  notable for long iron swords, heavy  knives, and burial in coffins or under stone heaps; findings with a later  date, but still of the middle period, include decorated scabbards, broad-  bladed spearheads, and wooden shields with iron supports. The final  period, showing Roman influence, is distinguished by peasant�s imple�  ments, such as iron sickles, scythes, axes, saws, and plowshares.</p><p>La Tour \l9-'tur\, Georges de (b.

He was well  known in his lifetime, especially for his depictions of candlelit subjects,  then was forgotten until the 20th century, when the identification of works  previously misattributed established his reputation as a giant of French  painting. His early works were painted in a realistic manner and influ�</p><p>enced by the dramatic chiaroscuro of  Caravaggio. The paintings of La  Tour�s maturity are marked by a star�  tling geometric simplification of the  human form and by the depiction of  interior scenes lit only by the glare  of candles or torches. His religious  paintings done in this manner have a  monumental simplicity and a still�  ness that expresses both contempla�  tive quiet and wonder. Little is  known of his life, and only four or  five of his paintings are dated.

He served in the French  army before becoming a fur trader in  the region north of Lake Superior (1726). From the Indians he learned of  a river that might lead to the Pacific Ocean, and with his sons he built a  string of fur-trading posts from Ontario to Manitoba (1731-38). Two sons  sent farther west became the first Europeans to explore areas of present-  day Nebraska, Montana, and Wyoming, and they claimed South Dakota  for France.

After studying dance in Paris, he opened his Choreographic Institute in  Zurich, Switz., in 1915 and later founded branches in Italy, France, and  central Europe. From 1919 to 1937 he worked in Germany, where in  1930-34 he was ballet director of the Berlin State Opera. In 1928 he pub�  lished his method for recording all forms of human motion, which enabled  choreographers to record the dancer�s steps and other body movements,  including their rhythm. In 1938 he joined his former pupil Kurt Jooss and  taught dance in England, where he later formed the Art of Movement Stu�  dio.

In classical eco�  nomics, labour is one of the three factors of production, along with capital  and land. Labour can also be used to describe work performed, including  any valuable service rendered by a human agent in the production of  wealth, other than accumulating and providing capital. Labour is per�  formed for the sake of its product or, in modern economic life, for the  sake of a share of the aggregate product of the community�s industry. The  price per unit of time, or wage rate, commanded by a particular kind of  labour in the market depends on a number of variables, such as the tech�  nical efficiency of the worker, the demand for that person�s particular  skills, and the supply of similarly skilled workers. Other variables include  training, experience, intelligence, social status, prospects for advance�  ment, and relative difficulty of the work. All these factors make it impos�  sible for economists to assign a standard value to labour. Instead,  economists often quantify labour hours according to the quantity and  value of the goods or services produced.</p><p>labour See parturition</p><p>labour economics Study of how workers are allocated among jobs,  how their rates of pay are determined, and how their efficiency is affected  by various factors.

Many factors influence how workers are utilized and how  much they are paid, including qualities of the labour force itself (such as  health, level of education, distribution of special training and skills, and  degree of mobility), structural characteristics of the economy (e.g., pro�  portions of heavy manufacturing, technology, and service industries), and  institutional factors (including the extent and power of labour unions and  employers� associations and the presence of minimum-wage laws). Mis�  cellaneous factors such as custom and variations in the business cycle are  also considered. Certain general trends are widely accepted by labour  economists; for instance, wage levels tend to be higher in jobs that involve  high risk, in industries that require higher levels of education or training,  in economies that have high proportions of such industries, and in indus�  tries that are heavily unionized.</p><p>labour law Body of law that applies to matters such as employment,  wages, conditions of work, labour unions, and labour-management rela�  tions. Laws intended to protect workers, including children, from abusive  employment practices were not enacted in significant numbers until the  late 19th century in Europe and slightly later in the U.S. In Asia and  Africa, labour legislation did not emerge until the 1940s and �50s.  Employment laws cover matters such as hiring, training, advancement,  and unemployment compensation. Wage laws cover the forms and methods  of payment, pay rates, social security, pensions, and other matters. Legis�  lation on working conditions regulates hours, rest periods, vacations, child  labour, equality in the workplace, and health and safety. Laws on trade  unions and labour-management relations address the status of unions, the  rights and obligations of workers� and employers� organizations, collec�  tive bargaining agreements, and rules for settling strikes and other disputes.  See also arbitration; mediation.</p><p>Labour Party British political party whose historic links with trade  unions have led it to promote an active role for the state in the creation  of economic prosperity and the provision of social services. In opposition  to the Conservative Party, it has been Britain�s major democratic socialist  party since the early 20th century. In 1900 the Trades Union Congress  and the Independent Labour Party (founded 1893) established the Labour  Representation Committee, which took the name Labour Party in 1906.  In 1918 it became a socialist party with a democratic constitution, and by  1922 it had supplanted the Liberal Party as the official opposition party. In  1924 James Ramsay MacDonald formed the first Labour government, with  Liberal support. The party was out of power from 1935 until a spectacu�  lar recovery in 1945 brought in Clement R. Attlee�s government (until  1951), which introduced a system of social welfare, including a national  health service, and extensive nationalization of industry. Labour regained  power under Harold Wilson (1964-70) and later James Callaghan (1974-  79), but it foundered because of economic problems and worsening rela�</p><p>tions with its trade-union allies. In 1983 Michael Foot�s radical program  resulted in a massive Labour defeat. Neil Kinnock moved the party toward  the centre, but only in 1997 did Tony Blair and his �New Labour� agenda  succeed in returning Labour to power.</p><p>labour union Association of workers in a particular trade, industry, or  plant, formed to obtain improvements in pay, benefits, and working con�  ditions through collective action. The first fraternal and self-help asso�  ciations of labourers appeared in Britain in the 18th century, and the era  of modern labour unions began in Britain, Europe, and the U.S. in the  19th century. The movement met with hostility from employers and gov�  ernments, and union organizers were regularly prosecuted. British union�  ism received its legal foundation in the Trade-Union Act of 1871. In the  U.S. the same effect was achieved more slowly through a series of court  decisions that whittled away at the use of injunctions and conspiracy laws  against unions. The founding of the American Federation of Labor (AFL)  in 1886 marked the beginning of a successful, large-scale labour move�  ment in the U.S. The unions brought together in the AFL were craft  unions, which represented workers skilled in a particular craft or trade.  Only a few early labour organizers argued in favour of industrial unions,  which would represent all workers, skilled or unskilled, in a single indus�  try. The Congress of Industrial Organizations (CIO) was founded by  unions expelled from the AFL for attempting to organize unskilled work�  ers, and by 1941 it had assured the success of industrial unionism by  organizing the steel and automotive industries (see AFL-CIO). The use of  collective bargaining to settle wages, working conditions, and disputes is  standard in all noncommunist industrial countries, though union organi�  zation varies from country to country. In Britain, labour unions displayed  a strong inclination to political activity that culminated in the formation  of the Labour Party in 1906. In France, too, the major unions became  highly politicized; the Confederation Generate du Travail (formed in  1895) was allied with the Communist Party for many years, while the  Confederation Frangaise Democratique du Travail is more moderate  politically. Japan developed a form of union organization known as enter�  prise unionism, which represents workers in a single plant or multiplant  enterprise rather than within a craft or industry.</p><p>Labov Mo-'bovV William (b. Dec. 4, 1927, Rutherford, N.J., U.S.) U.S.  linguist. After working for many years as an industrial chemist, Labov  began graduate work in 1961, focusing on regional and class differences  in English pronunciation on Martha�s Vineyard, Mass., and in New York  City, and ways to quantify phonetic change and variation. Most of his  later research dealt with the same issues in increasingly sophisticated  ways, culminating in his monumental Principles of Linguistic Change  (1994). The discovery that American English pronunciation was becom�  ing regionally more rather than less divergent countered popular belief  and attracted the attention of many outside his field.</p><p>Labrador Large peninsula, northeastern Canada. Divided between the  provinces of Quebec and Newfoundland and Labrador, it occupies an area  of about 625,000 sq mi (1,620,000 sq km). Its highest mountains are over  5,000 ft (1,520 m), and its coast is lined with islands. It forms the east�  ernmost portion of the plateau known as the Canadian Shield. Politically,  Labrador refers to the Newfoundland and Labrador portion of the penin�  sula; the Quebec portion is Ungava Peninsula. Political control of the  region was disputed by the two provinces until the Quebec-Newfoundland  border was established in 1927.</p><p>Labrador Current Surface oceanic current flowing southward along  the western side of the Labrador Sea. Originating at the Davis Strait, the  current is a combination of the West Greenland Current, the Baffin Island  Current, and inflow from Hudson Bay. It maintains temperatures of less  than 32�F (0�C) and has a low salinity. The current is limited to the con�  tinental shelf and reaches depths only slightly greater than 2,000 ft (600  m). It carries several thousand icebergs southward each year.</p><p>labradorite Vla-bro-.dor-.fiA Type of feldspar mineral in the plagioclase  series that is often valued as a gemstone and as ornamental material for  its red, blue, or green iridescence.

A practicing psy�  chiatrist in Paris for much of his career, Lacan emphasized the primacy of  language as the mirror of the unconscious mind and introduced the study  of language into psychoanalytic theory. His major achievement was his  reinterpretation of Sigmund Freud�s work in terms of structural linguistics.  He became a celebrity in France with Ecrits (1966; The Language of the  Self) and in the 1970s was a dominant figure in French cultural life as well  as a strong influence on American psychoanalytic and literary theory.</p><p>Lacandon \,la-kan-'don\ MAYAn Indians who live in a rich tropical rain�  forest on the border of Mexico and Guatemala. Largely isolated, they  maintained a traditional way of life until modern times, fishing, hunting,  and growing vegetables and fruits.

Their total number has declined, and only  several hundred remain.</p><p>lace Ornamental openwork fabric formed by the looping, interlacing,  braiding, or twisting of threads, originally primarily of linen. Almost all  high-quality artistic lace is made by one of two techniques: needle lace  involves a difficult technique that originated in Italy; bobbin lace is a more  widespread craft that originated in Flanders. The art of lace is a European  achievement. Fully developed lace did not appear before the Renaissance.  By 1600 lace had become a fabric of luxury and an important article of  commerce. The Industrial Revolution in the 19th century led to the use  of machines to produce less-expensive lace made of cotton, and lace  gradually disappeared from both men�s and women�s fashions. By 1920  the industry was dying. Fine handmade lace is still made in Belgium, Slo�  venia, and elsewhere, but chiefly as souvenirs.</p><p>Lacedaemon See Sparta</p><p>lacemaking Methods of producing lace. The popularity of handmade  laces led to the invention of lacemaking machines in the 19th century (see  John Heathcoat). Early models required intricate engineering mecha�  nisms. Later improvements included Nottingham-lace machines, prima�  rily for coarse lace, and Barmens machines. Schiffli lace, a type of  embroidery, is made by modern machines, evolved from a hand version,  using needles with points at each end. Many types of machine-made laces  are produced, frequently with geometrically shaped nets forming their  backgrounds. The high strength and comparatively low cost of man-made  fibre yams have made sheer laces widely available.</p><p>lacewing Any of numerous species of insects in the order Neuroptera,  especially those in the green lace�  wing and brown lacewing families.</p><p>The green lacewing has long, deli�  cate antennae, a slender greenish  body, golden- or copper-coloured  eyes, and two pairs of veined wings.</p><p>It is found worldwide and flies near  grasses and shrubs. It is also known  as a stinkfly because it emits a dis�  agreeable odour. The larva, with  prominent sucking mouthparts,  drains body fluids from aphids and  other soft-bodied insects. The brown  lacewing resembles the green lacewing but is smaller and brown.</p><p>Lachaise Ma-'shezV, Gaston (b. March 19, 1882, Paris, Fr.�d. Oct.  18, 1935, New York, N.Y., U.S.) French-born U.S. sculptor. Son of a  cabinetmaker, he was trained in the decorative arts and studied sculpture  at the Ecole des Beaux-Arts (1898-1904). He was a designer of Art Nou�  veau decorative objects for Rene Lauque before immigrating to the U.S. in  1906. His most famous work, Standing Woman (1912-27), a female nude  with ample breasts and thighs and sinuous, tapered limbs, typifies the  image he worked and reworked throughout his career. He is also known  for his portrait busts of John Marin, Marianne Moore, E.E. Cummings, and  others.

He is chiefly remembered for  Dangerous Liasions (1782), one of  the earliest psychological novels.  The epistolary novel of a noble  seducer and his female accomplice  who take unscrupulous delight in  their victims� misery, it caused an  immediate sensation and was banned  for years. Laclos later returned to the  army and ultimately rose to the rank  of general under Napoleon. His book  retained its popularity into the 21st  century, by which time it had been  adapted several times, for film and  for television.</p><p>Laconia \b-'ko-ne-9\, Gulf of  Inlet, southern Ionian Sea southern  coast of the Peloponnese, Greece.

He won the Wimbledon (1925, 1928) and French  (1925, 1927, 1929) singles titles and became the first foreigner to win the  U.S. championship twice (1926, 1927), the second time beating Bill Til-  den. He also won various doubles matches. Nicknamed �the Crocodile,�  he retired in 1929 to form a sportswear company that featured a croco�  dile (later an alligator) emblem on its clothes.</p><p>lacquerwork Any of a variety of decorative objects or surfaces, usu�  ally of wood, to which a coloured, highly polished, and opaque type of  varnish called lacquer has been applied. True lacquerwork is Chinese or  Japanese in origin. The technique was copied in Europe, where it was  known as �japanning,� but European lacquerwork lacks the hardness and  brilliance of Asian lacquer. True lacquer is the purified and dehydrated  sap of the Rhus vernicifera tree, native to China and cultivated in Japan.  Lacquer becomes extremely hard but not brittle on exposure to air and  takes a high polish. Many thin layers are applied, allowed to dry, and  smoothed before the surface is ready for decoration by carving, engrav�  ing, or inlay.</p><p>lacrosse (French: �the crosier�) Outdoor goal-scoring sport played with  sticks called crosses. A crosse has a long handle and a triangular head  with a mesh pouch for catching, carrying, and throwing a hard rubber  ball. The object of the game is to sling the ball into an opponent�s goal  (for one point). French settlers in Canada adapted the modem game from  an ancient American Indian activity (baggataway) that was at once sport,  combat training, and mystical ceremony. It became an organized sport in  the late 19th century. Modern teams have 10 players. The game is divided  into four periods of 15 minutes each. Lacrosse is especially popular as a  collegiate sport and is played by both men and women.

Mature milk sup�  plies nutrients, hormones, and substances that provide the infant with  immunity against infectious agents. Most physicians recommend that babies  be fed mother�s milk exclusively for the first six months and that nursing  continue through the first year. As the child is weaned, lactation tapers  off; while nursing continues, fertility is reduced. Problems with lactation  may involve hormones, suckling pattern, physical difficulties, or emo�  tional factors. Mothers taking certain drugs or with some diseases (e.g.,  AIDS) should not nurse, because of risks to the baby.</p><p>lactic acid Carboxylic acid found in certain plant juices, in blood and  muscle, and in soil. In blood it occurs in the form of its salts (lactates)  when glycogen is broken down in muscle; it can be reconverted to gly�  cogen in the liver. Stiffness and soreness after prolonged heavy exercise  are due to accumulated lactic acid in the muscles. The end product of  bacterial fermentation, lactic acid is the most common acidic constituent  of fermented milk products (e.g., sour milk and cream, cheese, butter�  milk, yogurt). It is used in other foods as a flavouring or preservative and  industrially in tanning leather and dyeing wool and as a raw material or  catalyst in many chemical processes.</p><p>lactobacillus Uak-to-bo-'si-losV Any of the rod-shaped, gram-positive  (see gram stain) bacteria that make up the genus Lactobacillus. They are  widely distributed in animal feeds, manure, and milk and milk products.  Various species are used commercially in the production of sour milks,  cheeses, and yogurt. Lactobacilli also play an important role in the manu�  facture of fermented vegetables (pickles and sauerkraut), beverages (beer,  wine, and juices), sourdough breads, and some sausages. They inhabit but  do not damage animal and human intestinal tracts. Commercial prepara�  tions of lactobacilli are used to restore normal intestinal flora after anti�  biotic therapy.</p><p>lactose Slightly sweet sugar (disaccharide) composed of two monosac�  charides, glucose and galactose, linked together. Lactose-intolerant adults,  and more rarely infants, cannot digest lactose because they lack the enzyme  (lactase) that splits it into simpler sugars and suffer diarrhea and bloating  when they eat foods containing it. Lactose, which makes up 2-8% of the  milk of mammals, is the only common sugar of animal origin. Commer�  cial lactose is obtained from whey, a liquid by-product of cheese. It is  used in foods, in pharmaceuticals, and in nutrient broths used to produce  penicillin, yeast, and riboflavin, and other products.</p><p>Ladakh \b-'dak\ Region, eastern Kashmir region, northwestern Indian  subcontinent.

India and Paki�  stan fought over it before peace negotiations in 1949 gave its southern por�  tion to India (which is part of the Indian state of Jammu and Kashmir) and  the rest to Pakistan. In the Sino-Indian War of 1962 China gained a portion  of northeastern Ladakh. The region�s boundaries are still in dispute.</p><p>Ladd-Franklin, Christine orig. Christine Ladd (b. Dec. 1, 1847,  Windsor, Conn., U.S.�d. March 5, 1930, New York, N.Y.) U.S. scientist</p><p>and logician. She fulfilled Ph.D.  requirements at Johns Hopkins Uni�  versity in the 1880s, but, because  women candidates were not recog�  nized, she was not awarded her  degree until 1926. In symbolic logic,  she reduced syllogistic reasoning to  an inconsistent triad with the intro�  duction of the antilogism, a form  that made the testing of deductions  easier. The Ladd-Franklin theory of  colour vision stressed increasing  colour differentiation with evolution  and assumed a photochemical model  for the visual system. Her principal  works are The Algebra of Logic  (1883), The Nature of Color Sensa�  tion (1925), and Color and Color  Theories (1929).</p><p>Ladies' Home Journal U.S.  monthly magazine, one of the oldest  in the country and long the trendset�  ter among women�s magazines.  Founded in 1883 as a supplement to the Tribune and Farmer (1879-85),  it began an independent publication in 1884. Under the editorship (1889�  1919) of Edward Bok, its circulation surpassed that of any other U.S. pub�  lication. Bok revolutionized the women�s magazine field by offering high-  quality fiction and nonfiction, establishing service departments that  answered letters from readers, and conveying a sense of intimacy. After  the mid-20th century Ladies � Home Journal was overtaken in circulation  by its rival, McCall�s.

Born to an ancient noble family  of great wealth, he was a courtier at the court of Louis XVI but sought</p><p>glory as a soldier. In 1777 he went to America, was appointed a major  general, became a close friend of George Washington, and fought with  distinction at the Battle of the Brandywine. He returned to France in 1779,  persuaded Louis to send a 6,000-man force to aid the colonists, and  returned to America in 1780 to command an army in Virginia and help  win the Siege of Yorktown. Hailed as �the Hero of Two Worlds,� he  returned to France in 1782, became a leader of liberal aristocrats, and was  elected to the Estates General in 1789. He presented the Declaration of the  Rights of Man and of the Citizen to the National Assembly. Elected com�  mander of the national guard of Paris, he sought to protect the king,  favouring a constitutional monarchy. When his guards fired on a crowd  of petitioners in the Champ de Mars (1791), he lost popularity and  resigned his position. He commanded the army against Austria (1792),  then defected to the Austrians, who held him captive until 1797. Return�  ing to France, Lafayette became a gentleman farmer.

He then  offered his aid to Gen. Andrew Jack-  son, who accepted Laffite�s help in  the Battle of New Orleans. After the  war Laffite returned to privateering  against the Spanish.</p><p>Laffitte \la-'fet\, Jacques (b. Oct.</p><p>24, 1767, Bayonne, France�d.

He was involved early in life with socialism and soon began to  support literary and artistic radicalism. Though his early works are char�  acterized by extreme pessimism, he declared his faith in humanity with  his great prose monologue The Triumph over Life (1927). In the 1930s  and �40s his writings protested fascism and brutality. The novel The Dwarf  (1944) was his first best-seller and his first undisputed critical success. He  won world recognition with the novel Barabbas (1950). He was awarded  the Nobel Prize for Literature in 1951.</p><p>Lagerlof Vla-gor-.lcefV Selma (Ottiliana Lovisa) (b.

At the southern edge of the Atlas Mountains, it was  built on two hills that are extensions of Mount Tizigarine. It was settled  in the 11th century and came under Moroccan and Ottoman control.  Seized by the French in 1852, it reverted to Algeria in 1962.</p><p>lagoon Area of relatively shallow, quiet water with access to the sea but  separated from it by sandbars, barrier islands, or coral reefs. Coastal  lagoons have low to moderate tides and constitute about 13% of the  world�s coastline. Their water is colder than the sea in winter and warmer  in summer. In warm regions, evaporation may more than balance any  freshwater input and may result in hypersaline water and even the buildup  of thick salt deposits. Coral-reef lagoons occur on marginal reefs such as  the Great Barrier Reef, but the most spectacular examples, some more  than 30 mi (50 km) across, are associated with Pacific atolls.</p><p>Lagos Vla-.gas, 'la-gos\ City (pop., 1999: urban agglomeration,  12,763,000) and chief port, Nigeria.

Its population is centered on  Lagos Island, on the Bight of Benin. Part of the kingdom of Benin in the  16th century, it was inhabited largely by the Yoruba. Beginning in 1808, as  Britain attempted to end the slave trade, Lagos came into increasingly  greater contact with the British. It was ceded to Britain in 1861, became a  crown colony, and was governed from Sierra Leone (1866-74) and as part  of the Gold Coast colony (1874-86). Joined with the protectorate of  Southern Nigeria in 1906, it was made the capital of the colony of Nigeria  in 1914. It was the capital (1960-91) of independent Nigeria until Abuja  became the new capital. It is a major trade and industrial centre.</p><p>Lagrange \la-'gra n zh\, Joseph-Louis later count de L'Empire (b.</p><p>Jan. 25, 1736, Turin, Sardinia-Piedmont�d.

In his widely  read and highly controversial book The Divided Self (196 0), his analysis  of schizophrenia led him to theorize that insecurity about one�s existence  prompts a defensive reaction in which the self splits into separate com�  ponents, generating psychotic symptoms, and he opposed standard schizo�  phrenia treatments such as hospitalization and electroshock. He even  opposed the concept of mental illness, viewing it as induced by family  relationships and society, and radically reconceived the role of the psy�  chiatrist. He later modified some of his controversial positions.</p><p>laissez-faire \,le-sa-'fer\ French "allow to do" Policy dictating a  minimum of governmental interference in the economic affairs of indi�  viduals and society. It was promoted by the physiocrats and strongly sup�  ported by Adam Smith and John Stuart Mill. Widely accepted in the 19th  century, laissez-faire assumed that the individual who pursues his own  desires contributes most successfully to society as a whole. The function  of the state is to maintain order and avoid interfering with individual ini�  tiative. The popularity of the laissez-faire doctrine waned in the late 19th  century, when it proved inadequate to deal with the social and economic  problems caused by industrialization.

The primary sources of lake water are melting  ice and snow, springs, rivers, runoff from the land surface, and direct pre�  cipitation. In the upper part of lakes there is a good supply of light, heat,  oxygen, and nutrients, well distributed by currents and turbulence. As a  result, a large number of diverse aquatic organisms can be found there.  The most abundant forms are plankton (chiefly diatoms), algae, and flagel�  lates. In the lower levels and in the sediments, the main forms of life are  bacteria.

Its  total area is 3,653,000 acres (1,478,300 hectares). Lake Clark, more than  40 mi (65 km) long, is the largest of its glacial lakes; it feeds rivers that  provide the most important spawning ground for red salmon in North  America. The park includes glaciers, waterfalls, and active volcanoes.</p><p>Lake District Mountainous region, administrative county of Cumbria,  northwestern England. Roughly coextensive with Lake District National  Park, the country�s largest, it occupies an area of 866 sq mi (2,243 sq  km). It contains numerous lakes, including Windermere (England�s larg�  est), Grasmere, and Coniston Water, as well as England�s highest moun�  tains, the loftiest being Scafell Pike, which rises to 3,210 ft (978 m). The  district was home to several English poets, including William Wordsworth,  Robert Southey, and Samuel Taylor Coleridge, who celebrated its landscape.  It became a national park in 1951.</p><p>Lake Dwellings Remains of various pre- and post-BRONZE Age settle�  ments within the margins of lakes in southern Germany, Switzerland,  France, and Italy. The dwellings appeal� to have been built on platforms  supported by piles above the water surface or above swampy areas along  the water�s edge. The platforms supported one- or two-room rectangular  huts with beaten clay floors. Cattle and sheep were raised in some of the  structures. Most dwellings seem to have burned, either by accident or by  attack. Because the Lake Dwellers usually rebuilt new villages on the  remains of the old, archaeologists were able to work out a cultural  sequence confirming that the Bronze Age immediately followed the Stone  Age.

The site  was settled in 1800, but it was abandoned after crop failures. Resettled  during the 1840s, it was promoted in 1850 as a summer resort, and Melvil  Dewey founded the Lake Placid Club there in 1895. It is a year-round rec�  reation area with numerous hotels, golf courses, ski resorts, and moun�  tain scenery.

They are greenish gray and covered  with pale spots. In spring, 5-lb (2.3-kg) lake trout are caught in shallow  water; in summer, fish of up to 100 lbs (45 kg) are trolled in deep water.  Lake trout were virtually eliminated from the Great Lakes by the sea lam�  prey, which entered through the Welland Canal in the 1930s. They have  been introduced in the western U.S., South America, Europe, and New  Zealand.</p><p>Lake Turkana remains Collection of hominin fossils found along the  shores of Lake Turkana (Lake Rudolf) in northwestern Kenya. The Koobi  Fora site, excavated by the Leakey family and others, has proved to be the  richest trove of hominin remains anywhere in the world, yielding fossils  that represent perhaps 230 individuals, including members of Homo habi-  lis, Homo erectus, and Australopithecus. On the western shore was found a  remarkably well-preserved skeleton of an 11-year-old boy (�Turkana  Boy�) later classified as H. ergaster or H. erectus and dated to c. 1.8 mil�  lion years ago. This surprisingly human specimen suggests that H.  ergaster may have been the direct ancestor of the hominins that left Africa  for Eurasia c. 1 million years ago.

Reacting against machine-produced jewelry featuring  precious gems, he designed elegant and fantastic jewelry with less con�  ventional gemstones (tourmaline, cornelian, etc.) and materials such as  horn. His designs contributed significantly to the Art Nouveau movement  and later the Art Deco movement.

Some lamas are considered  to be reincarnations of their predecessors; others have won respect for  their high level of spiritual development. The most honored of the rein�  carnate lamas is the Dalai Lama; second in spiritual authority is the Panchen  Lama. The process of discovering the new incarnation of a lama, espe�  cially the Dalai Lama, is elaborate and exacting. Oracular messages,  unusual signs during the lama�s death or during a birth thereafter, and  examinations of candidates identify a successor. The child thus identified  as the lama�s incarnation is given extensive monastic training from an  early age.</p><p>Lamar \b-'mar\, Mirabeau Buonaparte (b. Aug. 16, 1798, Lou�  isville, Ga., U.S.�d.

After an unsuccessful career as a merchant in Alabama, he served as sec�  retary to the governor of Georgia and later became editor of a newspaper  favouring states� rights. He then moved to Texas, where he became  involved in the independence struggle against Mexico. As a cavalry com�  mander, he helped win the Battle of San Jacinto (1836) and was later  appointed secretary of war in the provisional Texas government. He was  elected vice president of the Republic of Texas under Sam Houston, whom  he succeeded as president (1838�41).

He was one of the originators of the modem concept of the  museum collection, an array of objects whose arrangement constitutes a  classification under institutional sponsorship, maintained and kept up-to-  date by knowledgeable specialists. He seems to have been the first to relate  fossils to the living organisms to which they corresponded most closely.  His notion that acquired traits could be inherited (called Lamarckism) was  discredited after the 1930s by most geneticists except in the Soviet Union,  where it dominated Russian genetics until the 1960s (see Trofim Lysenko).

After brief  military service under Louis XVIII, he turned to literature, writing verse  tragedies and elegies. He is chiefly remembered for his successful first  collection of poetry, the musical, evocative Meditations poetiques (1820),  which established him as a key figure in French Romanticism. From 1830  he was active in politics, speaking for the working classes. After France�s  Second Republic was proclaimed in 1848, he briefly headed the provisional  government until the revolution was crushed.

From 1796 he was guardian of his sister, the writer  Mary Lamb (1764-1847), who, in a fit of madness (which proved recur�  rent), had killed their mother. He is best known for the often autobio�  graphical essays he wrote under the pseudonym Elia for London  Magazine, collected in Essays of Elia (1823) and The Last Essays of Elia  (1833).

With his brother Jean, he sketched a program of church  reform in Reflections on the State of the Church (1808) and in 1814 pro�  duced a defense of ultramontanism (papal authority). Ordained a priest in  1816, he wrote the acclaimed Essay on Indifference Toward Religion  (1817-23), which argued for the necessity of religion. After the July Revo�  lution (1830), he cofounded the journal L�Avenir to advocate democratic  principles and church-state separation. Its principles were condemned by  the pope in 1832. Lamennais�s The Words of a Believer (1834), written  in response, provoked another papal encyclical and led to Lamennais�s  severance from the church.

After an apprenticeship with a London goldsmith, he  registered his mark and opened a shop in 1713. Early in his career he  made simple vessels such as tankards and teapots in an unadorned Queen  Anne style; later he used more ornamentation.

The administrative  county comprises 12 districts. In the early Middle Ages it was a province  of the Anglo-Saxon kingdom of Northumbria. The region included the  ancestral lands of the house of Lancaster. In the Industrial Revolution it  became an important manufacturing region and a centre of the textile  industry. Lancaster and Preston are its major market and industrial cities;  it also has resort towns, including Blackpool, on the Irish Sea.</p><p>Lancaster, Burt(on Stephen) (b. Nov. 2, 1913, New York, N.Y.,  U.S.�d. Oct. 20, 1994, Century City, Calif.) U.S. film actor. He toured  with circuses as an acrobat in the 1930s and served in North Africa and  Italy during World War II. He first appeared in movie houses in The Kill�  ers (1946), which made him a star. He was noted for his portrayals of  physically tough, emotionally sensitive characters. Lancaster�s many  films include Come Back, Little Sheba (1952), From Here to Eternity  (1953), The Rose Tattoo (1955), Sweet Smell of Success (1957), Elmer  Gantry (1960, Academy Award), The Birdman of Alcatraz (1962), The  Leopard (1963), Atlantic City (1981), Local Hero (1983), and Field of  Dreams (1989).</p><p>Lancaster, house of Cadet branch of the house of Plantagenet that pro�  vided three kings of England in the 15th century (Henry IV, Henry V, Henry  VI). The family name first appeared in 1267, when the title of earl of Lan�  caster was granted to Henry Ill�s son Edmund (1245-96). Edmund�s grand�  son Henry (d. 1361) became the 1st duke of Lancaster, and the inheritance  fell to his youngest daughter, Blanche, and to her husband, John of Gaunt.  His son, Henry of Lancaster, became King Henry IV, and the duchy of Lan�  caster was merged in the crown. The Lancaster dynasty ended after the  defeat of Henry VI by Edward IV of the house of York (see Wars of the  Roses), and the Lancaster claims were passed on to the house of Tudor.</p><p>lancelet See amphioxus</p><p>Lancelot or Launcelot Vlan-so-.lat, , lan-s9- i lst\ One of the greatest  knights in Arthurian legend, the lover of Guinevere and the father of  Galahad. He first appeared in a 12th-century romance by Chretien de  Troyes, and he is a major character in Sir Thomas Malory�s Morte Dart-  hur. His full name, Sir Lancelot du Lac, refers to his upbringing by the  Lady of the Lake, the enchantress who carried him off in infancy and  trained him to be a model of chivalry before sending him to Arthur�s court.  There he became the favorite of King Arthur and the lover of Queen  Guinevere. His adultery with Guinevere caused him to fail in the quest  for the grail and set in motion the events that led to the destruction of  Camelot. He was displaced as the model knight by Galahad, his son by  the grailkeeper�s daughter Elaine.</p><p>Lancet, The British medical journal established in 1823, published  weekly from New York and London. Its founder and first editor, Thomas  Wakley, considered at the time a radical reformer, stated that the intent  of the new journal was to report on hospital lectures and describe impor�  tant cases of the day. It has since played a significant role in medical and  hospital reform movements in Britain and has become a highly presti�  gious medical journal around the world.</p><p>Lanchester Vlan-chos-torN, Frederick William (b.

Lanchester produced the first British  automobile, a one-cylinder, five-horsepower model, in 1896. After he  successfully produced improved models, financial backing enabled him  to produce several hundred cars over the next few years, vehicles notable  for a relative freedom from vibration, a graceful appearance, and a lug�  gage rack. He published an important paper (1897) on the principles of  heavier-than-air flight and later major texts on aeronautics.</p><p>Lancisi \lan-'che-ze\, Giovanni Maria (b.

He related the prevalence of malaria in swampy areas to the presence  of mosquitoes and recommended swamp drainage to prevent it. He linked  an increase in sudden deaths in Rome to causes such as hemorrhagic  stroke, cardiac enlargement and dilation, and growths on heart valves and  explored causes of heart enlargement. He also provided the first descrip�  tion of syphilitic aneurysms.</p><p>land In economics, the resource that encompasses the natural resources  used in production. In classical economics, the three factors of production  are land, labour, and capital. Land was considered to be the �original and  inexhaustible gift of nature.� In modern economics, it is broadly defined to  include all that nature provides, including minerals, forest products, and  water and land resources. While many of these are renewable resources,  no one considers them �inexhaustible.� The payment to land is called rent.  Like land, its definition has been broadened over time to include payment  to any productive resource with a relatively fixed supply.</p><p>Land, Edwin (Herbert) (b. May 7, 1909, Bridgeport, Conn., U.S.�d.  March 1, 1991, Cambridge, Mass.) U.S. inventor and physicist. After  briefly attending Harvard University, he cofounded the Land-Wheelwright  Laboratories in Boston in 1932. Interested in light polarization, in 1932  he developed the polarizer (which he called the Polaroid J sheet), for  which he envisioned numerous uses. By 1936, Land began to use types  of Polaroid material in sunglasses and other optical devices. It was later  used in camera filters and other optical equipment. In 1937 Land founded  the Polaroid Corp. in Cambridge, Mass. In 1947 he demonstrated the  revolutionary Polaroid Land Camera, which produced a finished print in  60 seconds; he introduced colour Polaroid film in 1963. His interest in  light and colour resulted in a new theory of colour perception. He received  more than 500 patents.</p><p>Land-Grant College Act of 1862 or Morrill Act Act of the U.S.  Congress (1862) that provided grants of land to states to finance the  establishment of colleges specializing in �agriculture and the mechanic  arts.� Named for its sponsor, Vermont Congressman Justin Smith Morrill  (1810-98), it granted each state 30,000 acres (12,140 hectares) for each  of its congressional seats. Funds from the sale of the land were used by  some states to establish new schools; other states turned the money over  to existing state or private colleges to create schools of agriculture and  mechanic arts (known as �A&amp;M� colleges). The military training required  in the curriculum of all land-grant schools led to the establishment of the  Reserve Officers Training Corps, an educational program for future army,  navy, and air force officers. The second Morrill Act (1890) initiated regu�  lar appropriations to support land-grant colleges, which came to include  17 predominantly African American colleges and 30 American Indian  colleges.</p><p>land mine Explosive charge buried just below the surface of the earth,  used in military operations against troops and vehicles. It may be fired by  the weight of vehicles or troops on it, the passage of time, or remote con�  trol. Though improvised land mines (buried artillery shells) were used in  World War I, they only became important in warfare during World War  II and have been widely used since. Most early mines had metal cases;  later models were sometimes made of other materials to prevent magnetic  detection. They are typically used to disrupt or prevent the massed attack  of tanks or infantry, but in post-World War II conflicts they have also  been used to render land useless to enemy civilian populations. A treaty  banning land mines�not signed by the U.S., Russia, and China�went  into effect in 1997. See also submarine mine.</p><p>land reform Deliberate change in the way agricultural land is held or  owned, the methods of its cultivation, or the relation of agriculture to the  rest of the economy. The most common political objective of land reform  is to abolish feudal or colonial forms of landownership, often by taking  land away from large landowners and redistributing it to landless peas-</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1072 I land tenure &#x25BA; landscape gardening</p><p>L_</p><p>N</p><p>ants. Other goals include improving the social status of peasants and  coordinating agricultural production with industrialization programs. The  earliest record of land reform is from 6th-century-BC Athens, where Solon  abolished the debt system that forced peasants to mortgage their land and  labour. The concentration of land in the hands of large landowners became  the rule in the ancient world, however, and remained so through the  Middle Ages and the Renaissance. The French Revolution brought land  reform to France and established the small family farm as the cornerstone  of French democracy. Serfdom was abolished throughout most of Europe  in the 19th century. The Russian serfs were emancipated in 1861, and the  Russian Revolution of 1917 introduced collectivization of agriculture,  attended by loss of capital and devastating famines. Land reform was  instituted in a number of other countries where communists came to  power, notably China. It remains a potent political issue in many parts of  the world.

After establishing herself as  a pianist and devoting much energy to musicological research, she had a  harpsichord made for her by Pleyel in Paris. She first performed on this  instrument at the Breslau Bach Festival in 1912, thus beginning the 20th-  century revival of the instrument and sparking a new international inter�  est in authentic performance practice. Her many recordings include the  first recording of Johann Sebastian Bach�s Goldberg Variations, and she  commissioned works such as Manuel de Falla�s Harpsichord Concerto and  Francis Poulenc�s Concert champetre.

She married  the socially prominent Edward  Langtry in 1874 and later became  known as the �Jersey Lily.� A famous  beauty, she caused a sensation when  she became the first society woman  to go on the stage, starring in She  Stoops to Conquer (1881). She  played to enthusiastic audiences in  England and the U.S., notably in As  You Like It.

A lan�  guage both reflects and affects a  culture�s way of thinking, and changes in a culture influence the devel�  opment of its language. Related languages become more differentiated  when their speakers are isolated from each other. When speech commu�  nities come into contact (e.g., through trade or conquest), their languages  influence each other. Most existing languages are grouped with other lan�  guages descended �genetically� from a common ancestral language (see  historical linguistics). The broadest grouping of languages is the language  family. For example, all the Romance languages are derived from Latin,  which in turn belongs to the Italic branch of the Indo-European language  family, descended from the ancient parent language, Proto-Indo-  European. Other major families include, in Asia, Sino-Tibetan, Austrone-  sian, Dravidian, Altaic, and Austroasiatic; in Africa, Niger-Congo, Afro-  Asiatic, and Nilo-Saharan; and in the Americas, Uto-Aztecan, AAaya,  Otomanguean, and Tupian. Relationships between languages are traced by  comparing grammar and syntax and especially by looking for cognates  (related words) in different languages. Language has a complex structure  that can be analyzed and systematically presented (see linguistics). All lan�  guages begin as speech, and many go on to develop writing systems. All  can employ different sentence structures to convey mood. They use their  resources differently for this but seem to be equally flexible structurally.  The principal resources are word order, word form, syntactic structure,  and, in speech, intonation. Different languages keep indicators of num�  ber, person, gender, tense, mood, and other categories separate from the  root word or attach them to it. The innate human capacity to learn lan�  guage fades with age, and languages learned after about age 10 are usu�  ally not spoken as well as those learned earlier.

It encompasses the philosophical study of linguistic mean�  ing (see semantics), the philosophical study of language use in communi�  cation (see pragmatics), and philosophical reflection on the nature and  scientific status of linguistic theories, known as the philosophy of linguis�  tics. Major areas of investigation have included the theory of reference  and the theory of truth. It was the dominant field in analytic philosophy for  most the 20th century.</p><p>Languedoc \la n g-'dok\ Historical and cultural region, south-central  France. Languedoc�s name is derived from the traditional language of  southern France, in which the word oc means �yes� (see Occitan lan�  guage). From 121 bc the region was part of the Roman province of Gal�  lia Narbonensis. With the fall of the Roman Empire, it was controlled by  the Visigoths in the 5th century. During the Middle Ages it came under  the counts of Toulouse. Religious wars (see Albigensian Crusade) in the  13th century brought it under the French crown. From the 16th to 18th  centuries Languedoc was the scene of Protestant persecution that culmi�  nated in the war of the Camisards. Protestant revolt led to its division into  departments.</p><p>Lanier \b-'nir\, Willie (Edward) (b. Aug. 21,1945, Clover, Va., U.S.)  U.S. gridiron football player.

As a member of the  House of Commons (1910-12, 1922^40), he became known as a social�  ist and poor-law reformer, and he led the British Labour Party from 1931  to 1935. Pacifist in his leanings, he was unwilling to call for economic  sanctions against Italy for its aggression in Ethiopia (1935), fearing it  might lead to war, and lost his party leadership post. In 1937 he visited  Adolf Hitler and Benito Mussolini in the vain hope that his personal influ�  ence could stop the movement toward war.</p><p>Lansdowne, Henry Charles Keith Petty-Fitzmaurice, 5th  marquess of (b.

Gladstone�s Liberal administration. In 1885, as governor-general of  Canada (1883-88), he helped settle the rebellion led by Louis Riel. As  viceroy of India (1888-94) under a Conservative government, he reorga�  nized the police, reconstituted legislative councils, closed Indian mints to  the free coinage of silver, and extended railway and irrigation works. As  secretary of war (1895-1900), he was blamed for British unpreparedness  in the South African War.

Jan. 15, 1983, Miami Beach, Fla., U.S.) Russian-born  U.S. gangster. His family immigrated to New York in 1911. As a young  man he joined Bugsy Siegel in auto theft, burglary, and liquor smuggling.  In 1931 he allegedly organized the murder of crime boss Joe Masseria  and joined Lucky Luciano in forming a national crime syndicate. By 1936  he had developed gambling operations in Cuba and the U.S., putting Sie�  gel in charge of Las Vegas. In the 1960s he extended his gambling empire  to the Bahamas and elsewhere in the Caribbean while continuing to run  narcotics-smuggling, prostitution, labour-racketeering, and extortion  rackets. His holdings in 1970 were estimated at $300 million. In 1979 the  House of Representatives Assassinations Committee linked Lansky with  Jack Ruby, the nightclub owner who killed Lee Harvey Oswald, the assas�  sin of Pres. John F. Kennedy. Though convicted of income-tax evasion in  1973, he remained free on appeals.</p><p>lantana \lan-'ta-n3\ Any of more than 150 shrubs that make up the  genus Lantana in the verbena family, native to the New World and Afri�  can tropics.

It became the seat of Lanzhou prefecture under the Sui dynasty (581-618  ad) and the capital of Gansu province in 1666. It was badly damaged dur�  ing the Muslim uprisings in 1864-75. A centre of Soviet influence in  northwestern China in the early 20th century, it was the terminus of the  2,000-mi (3,200-km) Chinese-Soviet highway that was used during the  Sino-Japanese War (1937�45) for the transport of Soviet supplies. It  developed as an industrial and cultural centre after World War II. It is the  seat of Lanzhou University.</p><p>Lao She Ylau-'sha\ orig. Shu Qingchun or Shu Sheyu (b.

Area: 91,429 sq mi (236,800 sq km). Population  (2005 est.): 5,924,000. Capital: Vientiane. Major ethnic groups include the  Lao-Lum (valley Lao), who make up about half of the population; the  Lao-Tai, a highland tribal people; the Lao-Theung (Mon-Khmer), descen�  dants of the region�s earliest inhabitants; and the Lao-Soung group,  including the Hmong and Man. Languages: Lao (official), English, Viet�  namese, French. Religions: Buddhism, traditional beliefs. Currency: kip.  Laos is largely mountainous, especially in the north; its highest point is  Mount Bia (9,245 ft [2,818 m]). Tropical forests cover more than half of  the country�s total land area; only a tiny portion of its total area is suitable  for agriculture. The floodplains of the Mekong River provide the country�s  only lowlands and its major wet-rice fields. Laos has a centrally planned  economy based primarily on agriculture (including rice, sweet potatoes,  sugarcane, cassava, and opium poppies) and international aid. It is a peo�  ple�s republic with one legislative house; its chief of state is the president,  and its head of government is the prime minister. The Lao people migrated  into Laos from southern China after the 8th century ad, displacing indig�  enous peoples. In the 14th century Fa Ngum founded the first Laotian  state, Lan Xang. Except for a period of rule by Myanmar (Burma; 1574-  1637), the Lan Xang kingdom ruled Laos until 1713, when it split into  three kingdoms�Vien Chan, Champassak, and Luang Prabang. During  the 18th century the rulers of the three Laotian kingdoms became vassals  of Siam (Thailand). France gained control of the region in 1893, and Laos  became a French protectorate. In 1945 Japan seized control and declared  Laos independent. The area reverted to French rule after World War II. By  the end of the First Indochina War, the leftist Pathet Lao movement con�  trolled two provinces of the country. The Geneva Conference of 1954 uni�  fied and granted independence to Laos.

He is traditionally named as the author of the  Daodejing, though modern scholars hold that the work had more than one  author. Legends about his life abound, but little or no certain information  survives. The historical Laozi, if he existed, may have been a scholar and  caretaker of sacred books at the royal court of the Zhou dynasty. Accord�  ing to legend, he was carried 72 years in his mother�s womb, and he met  Confucius as a young man. He is venerated as a philosopher by the Con-  fucianists, as a saint or god by the common people of China, and as a  divinity and the representative of the dao by Daoists.</p><p>laparoscopy \,la-p3-'ras-k9-pe\ or peritoneoscopy \,per-3t- 3 n-,e-  'as-k9-pe\ Procedure for inspecting the abdominal cavity using a laparo�  scope; also surgery requiring use of a laparoscope. Laparoscopes use  fibre-optic lights and small video cameras to show tissues and organs on  a monitor. Laparoscopic surgical procedures include gallbladder, appen�  dix, and tumour removal; tubal ligation; and hysterectomy. After carbon  dioxide is pumped in to expand the space for the instruments, small inci�  sions are made and the laparoscope and instruments inserted. Less inva�  sive than traditional (open) surgery, laparoscopy reduces postoperative  pain, recovery time, and length of hospital stay.</p><p>Lapidus Ma-'pi-dosN, Morris (b.

March 23,1749,  Beaumount-en-Auge, France�d. March 5, 1827, Paris) French mathema�  tician, astronomer, and physicist. He is best known for his investigations  into the stability of the solar system and the theory of magnetic, electri�  cal, and heat wave propagation. In his major lifework he applied New�  tonian gravitational theory to the solar system to explain deviations of the  planets from the orbits predicted by the theory (1773). Newton believed  that only divine intervention could explain the solar system�s equilibrium,  but Laplace established a mathematical basis for it, the most important  advance in physical astronomy since Newton. He continued to work on  elucidating planetary perturbations through the 1780s. A work published  in 1796 included his nebular hypothesis, which attributed the origin of the  solar system to the cooling and contracting of a gaseous nebula, a theory  that strongly influenced future thought on planetary origins.

The Laplace transform of a function is found  by integrating the product of that function and the exponential function  e~ pt over the interval from zero to infinity. The Laplace transform�s appli�  cations include solving linear differential equations with constant coeffi�  cients and solving boundary value problems, which arise in calculations  relating to physical systems.</p><p>Laplace's equation In mathematics, a partial differential equation  whose solutions (harmonic functions) are useful in investigating physical  problems in three dimensions involving gravitational, electrical, and mag�  netic fields, and certain types of fluid motion. Named for Pierre-Simon  Laplace, the equation states that the sum of the second partial derivatives  (the Laplace operator, or Laplacian) of an unknown function is zero. It can  apply to functions of two or three variables, and can be written in terms of  a differential operator as A F = 0, where A is the Laplace operator.</p><p>Lapland Region, northern Europe.</p><p>Located within the Arctic Circle, it  stretches across northern Norway,</p><p>Sweden, and Finland and into Rus�  sia�s Kola Peninsula.

The  district�s economy is largely based on tourism and agriculture.</p><p>Larousse \l9-'riis\, Pierre (Athanase) (b. Oct. 23, 1817, Toucy,  France�d. Jan. 3, 1875, Paris) French publisher, lexicographer, and ency�  clopaedist. Son of a blacksmith, he received a scholarship to study in Ver�  sailles. He founded his publishing house, Librairie Larousse, in Paris in  1852. It published textbooks, grammar books, and dictionaries, but his  major work, reflecting his desire �to teach everyone about everything,�  was the combined dictionary and encyclopaedia Grand dictionnaire uni-  versel du XIXe siecle, 17 vol. (1866-76). Librairie Larousse continues to  publish a multivolume encyclopaedia as well as dictionaries and smaller  encyclopaedias.</p><p>Larsa biblical Ellasar Ancient capital of Babylonia, located on the Eu�  phrates River in present-day southern Iraq. It was founded in prehistoric  times and flourished in a period of Sumerian decline (c. 2000-c. 1760  bc), when long-distance trade connected the Euphrates with the Indus  River valley. Hammurabi of Babylon gained control of the area in 1763 bc.</p><p>Larsen Ice Shelf Ice shelf in the northwestern Weddell Sea, adjoining  the eastern coast of the Antarctic Peninsula. It is named for Capt. Carl A.  Larsen, who explored the ice front by boat in 1893. The shelf originally  covered an area of 33,000 sq mi (86,000 sq km), excluding the numer�  ous small islands within it, but, as air temperatures over the Antarctic  Peninsula warmed slightly in the second half of the 20th century, the shelf  shrank dramatically. By the early 21st century, it covered only 40 percent  of its former area.</p><p>Lartigue \lar-'teg\, Jacques-Henri (-Charles-Auguste) (b. June  13, 1894, Courbevoie, Fr.�d. Sept. 12, 1986, Nice) French painter and  photographer. Born into a prosperous family, he was given a Brownie  camera at age seven. From the beginning, his photographs were invari�  ably informal shots of everyday subjects. In the 1910s and �20s Lartigue  enthusiastically photographed subjects such as automobile races, fashion�  able ladies at the seashore and the park, and kite flying. These photographs  reveal his free spirit and love of life, rather than a concern for photo�  graphic technique and craft, and often capture a sense of movement. When  his work was discovered in the 1960s, it was acclaimed for its departure  from formal, posed portraits and for its ingenuous charm and beguiling  spontaneity.</p><p>larva Active, feeding stage in the development of many animals, occur�  ring after birth or hatching and before the adult form is reached. Larvae  are structurally different from adults and often are adapted to a different  environment. Some species have free-living larvae but sessile (affixed)  adults, the moving larvae thus helping to spread the species; others have  aquatic larvae but terrestrial adults. Most larvae are tiny; many are dis�  persed by entering a host�s body, where the adult form of the parasite  emerges. Many invertebrates (e.g., cnidarians) have simple larvae. Flukes  have several larval stages, and annelids, mollusks, and crustaceans have  various larval forms. Insect larvae are called caterpillars, grubs, maggots,  or worms; the larval stage of many insects may last much longer than the  adult stage (e.g., some cicadas live 17 years as larvae and a week as  adults). Echinoderms also have larval forms. The larvae of frogs and toads  are called tadpoles. See also metamorphosis, pupa.</p><p>laryngeal Ms-'rin-joL cancer Malignant tumour of the larynx. The  larynx is affected by both benign and malignant tumours. Squamous-cell  carcinoma, the most common laryngeal malignancy, is associated with  smoking and alcohol consumption; it is more common in men. Prolonged  hoarseness without pain is the major symptom and should always be  investigated. Radiation therapy or surgery may be used to treat tumours.</p><p>laryngitis \,lar-9n-'jl-t9s\ Inflammation of the larynx, causing hoarse�  ness. Simple laryngitis usually occurs with infections such as the com�  mon cold. Other causes include inhalation of irritants. The larynx�s lining  becomes swollen and secretes mucus. In chronic laryngitis, caused by  excessive smoking, drinking, or vocal-cord use, the larynx is dry and has  polyps. Other types are caused by diphtheria spreading from the upper  throat, tuberculosis bacteria spreading from the lungs, and advanced syphi�  lis. The last can produce severe scarring and permanent hoarseness.</p><p>larynx \'lar-inks\ or voice box Hollow, tubular structure connecting  the pharynx with the trachea, through which air passes on the way to the  lungs. The larynx consists of a framework of cartilage plates, with a ridge  in front (Adam�s apple); the epiglottis, a flaplike projection up into the  throat that covers the airway during swallowing to keep food and liquid  from entering; and the vocal cords, whose vibration produces the sound  of the voice (see speech).

He devoted his life to protesting the mistreat�  ment of the Indians, with whom he worked in Guatemala, Peru, Cuba,  Nicaragua, and Mexico. His call for an end to the encomienda system  aroused implacable opposition.

The largest city  and chief port of the Canary Islands, it was founded in 1478 and served  as a base for the Spanish conquest of Tenerife and La Palma islands. It  grew after the port was constructed in 1883. It is a year-round resort; his�  toric sites include a 15th-century cathedral and the house of Christopher  Columbus.</p><p>Las Vegas City (pop., 2000: 478,434), southeastern Nevada, U.S. It is  famous for its luxury hotels, casinos, and nightclubs, located in the area  known as �the Strip.� Mormons from Utah settled the site in 1855 and  abandoned it in 1857. It became a railroad town in 1905 and was incor�  porated in 1911. Gambling was legalized in 1931, and Las Vegas  expanded rapidly after 1940. Its connections to crime syndicates began  in 1946, when Bugsy Siegel opened the Flamingo Hotel. By the early 21st  century it was one of the country�s fastest-growing metropolitan areas,  attracting a year-round population as well as tourists.</p><p>Lascaux \la-'sko\ Grotto Cave near Montignac, Fr., that contains per�  haps the most outstanding known display of prehistoric art. Discovered  in 1940, it consists of a main cavern and several steep galleries, all mag�  nificently decorated with engraved, drawn, and painted animals, some of  them portrayed in a �twisted perspective.� Among the most notable  images are four great aurochs bulls, a curious unicorn-type animal that  may represent a mythical creature, and a rare narrative composition  involving a bird-man figure and a speared bison. About 1,500 bone</p><p>engravings have also been found at the site, which has been dated to the  late Aurignacian period (c. 15,000 bc). Because of heavy tourist traffic,  the cave was closed to the public in 1963, but a full-scale facsimile, Las�  caux II, was opened in 1983. See also rock art.</p><p>laser Device that produces an intense beam of coherent light (light com�  posed of waves having a constant difference in phase). Its name, an acro�  nym derived from �light amplification by stimulated emission of  radiation,� describes how its beam is produced. The first laser, constructed  in 1960 by Theodore Maiman (born 1927) based on earlier work by  Charles H. Townes, used a rod of ruby. Light of a suitable wavelength from  a flashlight excited (see excitation) the ruby atoms to higher energy lev�  els. The excited atoms decayed swiftly to slightly lower energies (through  phonon reactions) and then fell more slowly to the ground state, emitting  light at a specific wavelength. The light tended to bounce back and forth  between the polished ends of the rod, stimulating further emission. The  laser has found valuable applications in microsurgery, compact-disc play�  ers, communications, and holography, as well as for drilling holes in hard  materials, alignment in tunnel drilling, long-distance measurement, and  mapping fine details.</p><p>Lashley, Karl S(pencer) (b.

He taught at the Univer�  sities of Minnesota (1920-29) and Chicago (1929-35) and at Harvard  University (1935-55). In Brain Mechanisms and Intelligence (1929), he  demonstrated that certain types of learning are mediated by the cerebral  cortex as a whole, refuting the view that every psychological function is  localized at a specific place on the cortex, and he showed that some parts  of the brain system (e.g., the visual system) can take over the functions  of other parts. He also studied the cortical basis of motor activities and  the relation between brain mass and learning ability. His paper �The Prob�  lem of Serial Order in Behavior� (1951) played a major supporting role  in the revolt against simple associative psychology.</p><p>Lasker, Emanuel (b. Dec. 24, 1868, Berlinchen, Prussia�d. Jan. 11,  1941, New York, N.Y., U.S.) German chess master and mathematician.  He first won the world chess championship in 1894 and retained the title  until his defeat by Jose Capablanca in 1921; his term remains the longest  reign as champion. As the first chess master to demand high fees, he  helped strengthen the financial status of chess professionals. He wrote the  classic Common Sense in Chess (1896) as well as books on mathematics  and philosophy. As a Jew, he was forced to leave Nazi Germany in 1933.  With the loss of his property, he ended his eight-year retirement from  chess, once again competing at the highest level.</p><p>Laski, Harold J(oseph) (b. June 30, 1893, Manchester, Eng.�d.

Educated at the University of Oxford, he taught at McGill Univer�  sity and Harvard University before returning to Britain to work for the  Labour Party. He later taught at the London School of Economics (1926-  50). He argued in works such as The State in Theory and Practice (1935)  that the economic difficulties of capitalism might lead to the destruction of  political democracy, and he came to view socialism as the only alternative  to fascism. He was an assistant to Clement R. Attlee during World War II.</p><p>Lassalle \la-'sal\, Ferdinand orig. Ferdinand Lasal (b. April 11,  1825, Breslau, Prussia�d.

He took part in  the revolution of 1848-49 and estab�  lished contact with Karl Marx and  Friedrich Engels. In 1859 he settled in  Berlin and became a political jour�  nalist. His advocacy of an evolution�  ary approach to socialism through a  democratic constitutional state based  on universal suffrage led to his  gradual estrangement from Marx. He  helped form the General German  Workers� Association (1863) and  was elected its president, but associ�  ates rebelled against his authoritarian  leadership. In 1864 he went to Swit�  zerland for a rest, fell passionately in love, and was killed at age 39 in a  duel with the woman�s former fiance.</p><p>Lassalle, c. 1860</p><p>ARCHIV FUR KUNST UND GESCHICHTE, BERLIN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Lassen Peak &#x25BA; Latin alphabet I 1079</p><p>Lassen Peak or Mount Lassen Volcano, southern end of the Cascade  Range, northeastern California, U.S. It erupted on May 30, 1914, and inter�  mittently thereafter until 1921.

He began as a choirboy (with such a  beautiful voice that he is said to have been kidnapped to sing elsewhere),  and his first known position was in service to the Gonzaga family in Italy  (1544). After 1556 he was based in Munich as kapellmeister to the duke  of Bavaria, but he pursued an international career, traveling in Italy, Ger�  many, Flanders, and France. He wrote more than 1,200 works, in every  contemporary style and genre, sacred (including some 60 masses and 500  motets) and secular (including hundreds of madrigals and chansons), his  attention to the correspondence of music and words being especially  remarkable. Because of his range of styles (he always kept up with fash�  ion) and because his works were printed widely during and after his life�  time, he influenced many composers and is regarded as one of the greatest  masters of his century.</p><p>Last Mountain Lake Lake, southern central Saskatchewan, Canada.

Heat of fusion is the latent heat associated with melting a  solid or freezing a liquid. Heat of vaporization is the latent heat associ�  ated with vapourizing a liquid or condensing (see condensation) a vapour.  For example, when water reaches its boiling point and is kept boiling, it  remains at that temperature until it has all evaporated; all the heat added  to the water is absorbed as latent heat of vaporization and is carried away  by the escaping vapour molecules.</p><p>Later Le \'le\ dynasty (1428-1788) Greatest and longest-lasting  dynasty of traditional Vietnam. Its founder, Le Loi, drove the Chinese out  of Vietnam and began the process of recovering the southern portion of  the region from the kingdom of Champa. In 1471 the dynasty�s greatest  ruler, Le Thanh Tong (d. 1497), completed that work. He divided the  country into provinces patterned on the Chinese model and established a  triennial Confucian civil-service examination. After 1533 the Le rulers  were only theoretically supreme, real power being held by the Trinh and  Nguyen families. In 1771 a peasant uprising toppled the dynasty.</p><p>laterality or hemispheric asymmetry Characteristic of the  human brain in which certain functions (such as language comprehension)  are localized on one side in preference to the other. One example is hand�  edness (the tendency to use one hand or the other to perform activities):  Since the left and right cerebral hemispheres control the right and left  sides of the body, respectively, right-handed people are typically left-  dominant in terms of hemispheric control of various motor functions and  also with respect to seeing (right-eyed) and language comprehension. Paul  Broca first identified the brain centre for articulate speech in what is now  called Broca�s area. Later researchers discovered that functions involving  logical or sequential analysis generally reside in the left hemisphere, while  the right hemisphere seems to control processing of spatio-visual infor�  mation and musical relations. More left-handers than right-handers dis�  play a reversal of hemispheric specialization or a more even distribution  of functions between the two hemispheres. There is no general agreement  about whether laterality is genetically transmitted, developed during ges�  tation, or learned.</p><p>Lateran Council Any of five ecumenical councils of the Roman Catho�  lic church held in the Lateran Palace in Rome. The First Lateran Council  (1123), held during the papacy of Calixtus II, reiterated decrees of earlier  ecumenical councils (condemning simony, forbidding clergymen to marry,  etc.). The Second Lateran Council (1139) was called by Innocent II to end  the schism created by the election of a rival pope. The Third Lateran  Council (1179), held during the papacy of Alexander III, established a two-  thirds majority of the College of Cardinals as a requirement for papal elec�  tion and condemned the heresies of the Cathari. Innocent III called the  Fourth Lateran Council (1215) in an effort to reform the church; its  decrees obliged Catholics to make a yearly confession, sanctioned the doc�  trine of transubstantiation, and made preparations for a new Crusade. The  Fifth Lateran Council (1512-17), convoked by Julius II, affirmed the  immortality of the soul and restored peace among warring Christian rulers.</p><p>Lateran Treaty or Lateran Pact (1929) Pact of mutual recognition  between Italy and the Vatican, signed in the Lateran Palace, Rome. The  Vatican agreed to recognize the state of Italy, with Rome as its capital, in  exchange for formal establishment of Roman Catholicism as the state reli�  gion of Italy, institution of religious instruction in the public schools, the  banning of divorce, and recognition of papal sovereignty over Vatican  City and the complete independence of the pope. A second concordat in  1985 ended Catholicism�s status as the state religion and discontinued  compulsory religious education.</p><p>laterite Vla-to-.rfiA Soil layer rich in iron oxide and sometimes aluminum,  derived from a wide variety of rocks by leaching.

Laterite is blackish brown  to reddish and has been used as an iron ore and, in Cuba, as a source of  nickel.</p><p>latex Any of several natural or synthetic colloidal suspensions (see col�  loid). Some latexes occur naturally in the cells of plants such as chicle and  rubber trees. They are complex mixtures of organic compounds, including  various gum resins, fats, or waxes and, in some instances, poisonous com�  pounds, suspended in a watery medium with dissolved salts, sugars, tan�  nins, alkaloids, enzymes, and other substances from which the latex (or  natural rubber, the only available rubber until 1926) can be concentrated,  coagulated, and vulcanized. Synthetic latexes (e.g., neoprene), made by  emulsion polymerization from styrene-butadiene copolymer, acrylate resins,  polyvinyl acetate, or other materials, are used as paints and coatings; the  plastic, dispersed in the water, forms films by fusion as the water evapo�  rates.</p><p>lathe Vlath\ Machine tool that performs turning operations in which  unwanted material is removed from a workpiece rotated against a cutting  tool. Lathes are among the oldest and most important machine tools, used  in France from 1569 and important in the Industrial Revolution in England,  when they were adapted for metal cutting (see Henry Maudslay). Lathes  (usually called engine lathes) today have a power-driven, variable-speed  horizontal spindle to which the workholding device is attached. Opera�  tions include turning straight or tapered cylindrical shapes, grooves,  shoulders, and screw threads and facing flat surfaces on the ends of cylin�  drical parts. Internal cylindrical operations include most of the common  hole-machining operations, such as drilling, boring, reaming, counterbor�  ing, countersinking, and threading with a single-point tool or tap.

The son of a prosperous  yeoman farmer, he was educated at the University of Cambridge, where  he came into contact with the doctrines of Martin Luther and converted to  Protestantism. He supported Henry VIII�s attempt to obtain a marriage  annulment but was later excommunicated for refusing to accept the exist�  ence of purgatory or the need to venerate saints. He made a complete sub�  mission and briefly served as bishop of Worcester (1535-39). Again  imprisoned on suspicion of heresy, he was freed with the accession of  Edward VI, during whose brief reign he preached extensively. On Mary  I�s accession and the subsequent reversion to Catholicism, he was arrested  for treason and burned at the stake.</p><p>Latin alphabet or Roman alphabet Most widely used alphabet,  the standard script of most languages that originated in Europe.

The colonial era in Latin America began in the 15th-  16th centuries when explorers such as Christopher Columbus and Amerigo  Vespucci made voyages of discovery to the New World. The conquistado-  Res who followed, including Hernan Cortes and Francisco Pizarro, brought  Spanish rule to much of the region. In 1532 the first Portuguese settle�  ment was made in Brazil. The Roman Catholic church soon established  many missions in Latin America. Roman Catholicism is still the chief reli�  gion in most Latin American countries, though the number of Protestants  and Evangelicals has grown. Spanish and Portuguese colonists arrived in  increasing numbers; they enslaved the native Indian population, which  was soon decimated by ill treatment and disease, and then imported Afri�  can slaves to replace them. A series of movements for independence, led  by Jose de San Martin, Simon Bolivar, and others, swept Latin America  in the early 19th century. Federal republics were promulgated across the  region, but many of the new countries collapsed into political chaos and  were taken over by dictators or military juntas, a situation that persisted  into the 20th century. In the 1990s a trend toward democratic rule  reemerged; in socialist-run countries many state-owned industries were  privatized, and efforts toward regional economic integration were accel�  erated.</p><p>Latin American arts Visual, performing, and literary arts that devel�  oped in Mesoamerica, Central America, South America, and the Carib�  bean after contact with the Spanish and Portuguese beginning in 1492  and 1500, respectively. When Europeans arrived, they came with artistic  traditions dating back to antiquity. For centuries, indigenous American  peoples had similarly formed civilizations with their own unique artistic  practices (see Native American arts). The importation of African slaves led  to the presence of long-standing African arts in the region as well (see  African arts). At the time of colonization, the architecture of many native  centres was destroyed and replaced with European-style churches and  buildings. During this period, a combination of European and indigenous  imagery led to unique religious sculptural and decorative art forms. As  more European artists immigrated to the new land, Iberian artists brought  with them elements of the styles that were current in Europe�such as the  Renaissance, Baroque, and Rococo�to art and architecture. The most  notable regional style of the 18th century was known as Churrigueresque,  an elaborately decorative style used in architecture, sculpture, and deco�  rative arts. Throughout the 19th and 20th centuries, Latin American art�  ists and architects continued to experiment with a variety of Western  styles�including Romanticism, Neoclassicism, Modernism, and postmod�  ernism �but increasingly adapted them to reflect Latin American themes  and, often, political concerns. Indigenous music was varied before colo�  nization. The main instruments seem to have been rattles or shakers (e.g.,  maracas) and flutes of numerous kinds, including panpipes. Under Euro�  pean influence, harps, violins, and guitars were adopted (see mariachi).  Indigenous scales were three- or five-tone, and choral singing in parallel  lines was common in some areas. Spanish and Portuguese music contrib�  uted verse forms and self-accompanied solo singing. African influences  on rhythm have included the use of repetitive patterns to accompany  extended improvisation and the prevalence of two- and four-beat patterns,  particularly in Caribbean music; the African tradition can also be seen in  the use of drums and of syncopation. Iberian dance rhythms and features,  such as hand clapping and the use of scarves and handkerchiefs, carried  over into many hybrid forms of music and dance. Especially in the 20th  century, forms of popular music and dance�such as salsa, tango, samba,  and bossa nova�represented a blending of native and Western traditions.  During the colonial period, Latin American literature reflected trends in  Spanish and Portuguese literature, and it consisted mostly of chronicles  of conquest. As the colonies developed their own character and moved  towards independence, patriotic writings became prominent. In the mid-  19th century, the cuadro de costumbres, or sketch of contemporary cus�  toms, developed into a realistic novel of manners. Beginning in the late  19th century, authors in the Modernismo movement focused on �art for  art�s sake.� Latin American literature came into its own in the 20th cen�  tury, with movements such as magic realism gaining international promi�</p><p>nence.

At its  founding in 1960 LAFTA included Argentina, Brazil, Chile, Mexico, Para�  guay, Peru, and Uruguay; by 1970 Ecuador, Colombia, Venezuela, and  Bolivia had joined. The organization aimed to remove all trade barriers  over 12 years, but its members� geographic and economic diversity made  that goal impossible. LAFTA was superseded in 1980 by the LAIA, which  established bilateral trading agreements between members, which were  divided into three groups according to their level of economic develop�  ment. Cuba was admitted with observer status in 1986, and it became a  full member in 1999.

Originally spoken by small groups of  people living along the lower Tiber River, Latin spread with the growth of  Roman political power, first throughout Italy and then through most of  western and southern Europe and the central and western Mediterranean  coastal regions of Africa. The earliest known Latin inscriptions date from  the 7th century bc; Latin literature dates from the 3rd century bc. A gap  soon appeared between literary (classical) Latin and the popular spoken  language, Vulgar Latin. The Romance languages developed from dialects  of the latter. During the Middle Ages and much of the Renaissance, Latin  was the language most widely employed in the West for scholarly and  literary purposes. Until the latter part of the 20th century, its use was  required in the liturgy of the Roman Catholic church.</p><p>latite \Ta-,tIt\ or trachyandesite \tra-ke-'an-d3-,zlt\ Type of igneous  rock that is abundant in western North America.

The combination of merid�  ians of longitude and parallels of latitude establishes a grid by which exact  positions can be determined: for example, a point described as 40� N, 30�  W is located 40� of arc north of the Equator and 30� of arc west of the  Greenwich meridian.</p><p>Latium \'la-she-om\ Ancient area, west-central Italy, on the Tyrrhenian  Sea. The Latins (or Latini) came from Indo-European tribes that settled  in the Italian peninsula during the 2nd millennium bc. By 500 bc the cit�  ies of Latium had formed the Latin League. War erupted between Rome  and the Latins in 340 bc and ended in 338 bc with the defeat of the Lat�  ins and the dissolution of the league.</p><p>Lafreille \la-'tray\, Pierre-Andre (b. Nov. 29, 1762, Brive-la-  Gaillarde, Fr.�d. Feb. 6, 1833, Paris) French zoologist, regarded as the  father of entomology. An ordained priest, in 1796 he published his Sum�  mary of the Generic Characteristics of Insects, Arranged in a Natural  Order, which led to his becoming head of entomology at the National  Museum of Natural History. His principal later work was his Compre�  hensive Natural History of Crustaceans and Insects (14 vol., 1802�05).  The two works, representing the first detailed classification of insects and  crustaceans, mark the beginnings of modern entomology. In 1829 he took  the professorial chair vacated by Jean-Baptiste Lamarck.</p><p>Latrobe \b-'trob\, Benjamin Henry (b. May 1, 1764, Fulneck, York�  shire, Eng.�d. Sept. 3, 1820, New Orleans, La., U.S.) British-U.S. archi�  tect and civil engineer. He immigrated to the U.S. in 1795. His first  important building was the State Penitentiary in Richmond, Va. In 1798,  in Philadelphia, he designed the Bank of Pennsylvania, considered the first  U.S. monument of the Greek Revival style. Pres. Thomas Jefferson  appointed him surveyor of public buildings. Latrobe inherited the task of  completing the U.S. Capitol, and later rebuilt it after its destruction by the  British. In Baltimore he designed the country�s first cathedral (1818).

An infantry division com�  mander in World War II, he was imprisoned by the Germans (1940^13),  but he escaped to North Africa. In 1944 he led the French army in the  Allied landing operations in southern France and in the drive across  France into southern Germany and Austria. He represented France at the  signing of the German capitulation (1945). In 1950�51 he commanded  French troops in the First Indochina War against the Viet Minh. He was  made a marshal of France posthumously.</p><p>Latvia officially Republic of Latvia Country, northeastern Europe,  along the shores of the Baltic Sea and the Gulf of Riga. Area: 24,938 sq mi  (64,589 sq km). Population (2005 est.): 2,299,000. Capital: Riga. Less than</p><p>three-fifths of the population are Latvians,  or Letts, who speak Latvian, one of two sur�  viving Baltic languages. Russians make up  about one-third of the population. Lan�  guages: Latvian (official), Russian. Reli�  gion: Christianity (Protestant, Roman Catholic, Eastern Orthodox).  Currency: lats. The landscape is an undulating plain, with fairly flat low�  lands alternating with hills. Latvia is a fully industrialized country. Heavy  industry (notably the production of metals, ships, and railcars) once was  more important than it is today; now leading manufactures include alco�  holic beverages, wood products, foodstuffs, and textiles. Latvia is a mul�  tiparty republic with one legislative body; its chief of state is the president,  and the head of government is the prime minister. It was settled by the  Balts in ancient times. They came under the overlordship of the Varan�  gians, or Vikings, in the 9th century and were later dominated by their  German-speaking neighbours to the west, who Christianized Latvia in the  12th�13th century. The Order of the Brothers of the Sword conquered  Latvia by 1230 and established German rule. From the mid-16th to the  early 18th century the region was split between Poland and Sweden, but  by the end of the 18th century all of Latvia had been annexed by Russia.  Latvia declared its independence after the Russian Revolution of 1917. In  1939 it was forced to grant military bases to the Soviet Union, and in 1940  the Soviet Red Army invaded. Held by Nazi Germany (1941-44), the  country was recaptured by the Soviets and incorporated into the Soviet</p><p>Union. With the breakup of the Soviet Union, Latvia gained its indepen�  dence in 1991. Subsequently it sought to privatize the economy and build  ties with western Europe (becoming a member of the European Union in  2004), as well as to improve uneasy relations with Russia.</p><p>Latvian language or Lettish language East Baltic language spo�  ken by some two million people in the Republic of Latvia and in diaspora  communities, including about 85,000 speakers in North America. Like  Lithuanian, it is sparsely attested until the first printed books in Latvian  appear in 1585-86. The essentials of the present orthography, which  employs the Latin alphabet with a number of diacritics, were adopted in  1908. Literary Latvian is based on the dialect spoken in Riga, Latvia�s  capital, though in recent years there has been a resurgence of literature in  High Latvian (Latgalian), the dialect of eastern Latvia. Relative to Lithua�  nian, Latvian has undergone a number of striking sound changes, though  the grammatical structures of the two languages are similar.</p><p>Laud, William (b. Oct. 7, 1573, Reading, Berkshire, Eng.�d. Jan. 10,  1645, London) Archbishop of Canterbury (1633-45) and religious adviser  to Charles I. He became a privy councillor in 1627 and bishop of London  in 1628, devoting himself to combating Puritanism and enforcing strict  Anglican ritual. By the time he became archbishop of Canterbury, he had  extended his authority over the whole country. He attacked the Puritan  practice of preaching as dangerous, and he had Puritan writers such as  William Prynne mutilated and imprisoned. Aided by his close ally the 1st  earl of Strafford, Thomas Wentworth, Laud used his influence over the  king to influence government social policy. By 1637, opposition to Lau-  dian reppression had grown, and Laud�s attempts to impose Anglican  forms of worship in Scotland provoked fierce resistance. In 1640 the Long  Parliament met, and Laud was accused of high treason. His trial, which  began in 1644 and was managed by Prynne, resulted in Laud�s convic�  tion and beheading.</p><p>Lauder Vlo-dorX, Estee orig. Josephine Esther Mentzer (b.

Their innovative marketing techniques led to huge success from  the 1960s on. Her son Leonard was named chief executive officer in 1982.  The company�s fragrance and cosmetics products, including Clinique cos�  metics, Aramis men�s products, as well as specialty lines such as Bobbi  Brown, Origins, and Aveda, are sold in more than 130 countries. By the  early 21st century the company was worth about $10 billion.</p><p>Laue \'lau-9. Max (Theodor Felix) von (b. Oct. 9, 1879, Pfaffen-  dorf, near Koblenz, Ger.�d. April 23, 1960, Berlin, W.Ger.) German  physicist. He taught at the University of Berlin (1919-43). He was the  first to use a crystal to diffract X-rays, demonstrating that X-rays are elec�  tromagnetic radiation similar to light and that the molecular structure of  crystals is a regularly repeating arrangement. For his work in crystallog�  raphy he received the 1914 Nobel Prize for Physics. He championed Albert  Einstein�s theory of relativity and studied the quantum theory, the Comp�  ton effect, and the disintegration of atoms.</p><p>Lauenburg Vlau-on-.burkV Region and former duchy, northern Ger�  many. It was established as a duchy under the Ascanian dynasty in the  13th century. In 1728 George Louis, elector of Hanover, became its ruler,  thereby attaching it to Hanover. It came under Prussia after the Danish-  Prussian War of 1864. The duchy was abolished in 1918, and the region  has been part of the state of Schleswig-Holstein since 1946.</p><p>laughing gas See nitrous oxide</p><p>laughing jackass See kookaburra</p><p>Laughlin \Tak-lin\, James (b.

Bom to a wealthy  family, Laughlin founded New Directions press in 1936 after graduating  from Harvard. He established the company initially to publish ignored yet  influential writers, including William Carlos Williams and Ezra Pound, a  friend and major influence on his life and work. New Directions editions of  such authors as Dylan Thomas, Tennessee Williams, and Hermann Hesse (one  of the many foreign authors it published in translation) eventually made the  house, despite its small size, one of the most distinguished literary pub�  lishers in the U.S. Its inexpensive pocket-sized volumes had distinctive  black-and-white covers that made them recognizable in any bookstore.</p><p>Laughton Vlo-tYA, Charles (b.

With his bulky frame and ordinary face Laughton defied Holly�  wood typecasting and emerged as one of the most versatile performers of  his generation. He played a wide range of character roles in films such as  Mutiny on the Bounty (1935), Ruggles of Red Gap (1935), The Hunch�  back of Notre Dame (1939), Witness for the Prosecution (1957), and  Advise and Consent (1962). He directed the memorable The Night of the  Hunter (1955).</p><p>lauma \'lau-ma\ In Baltic folklore, a fairy who appeared as a beautiful  naked maiden with long blond hair. Laumas lived in the forest near water  or stones. They yearned for children, and as they were unable to give birth,  they often kidnapped babies to rear as their own. Sometimes they mar�  ried mortal men and became excellent wives, perfectly skilled in domes�  tic work. Highly temperamental, laumas were seen as benevolent,  motherly beings, helpful to orphans and poor girls but extremely vindic�  tive when angered, particularly by disrespectful men. In Latvia and  Lithuania in recent centuries, lauma has come to refer to a witch or hag.</p><p>Launcelot See Lancelot</p><p>Launceston \T6n-s9-ston\ formerly Patersonia City (pop., 2001:  57,685) and port, northeastern Tasmania, Australia.

An export  hub for a fertile agricultural region, it also has industries, including  machine-making factories. One of the world�s first hydroelectric stations  (built in 1895) lies within the city on the South Esk River.</p><p>launch vehicle Rocket system that boosts a spacecraft into Earth orbit  or beyond Earth�s gravitational pull. A wide variety of launch vehicles  have been used to lift payloads ranging from satellites weighing a few  pounds (or kilograms) to large modular components of space stations.  Most launch vehicles are expendable (one-use) systems; many early ones  were derived from intercontinental ballistic missiles (see ICBM). The Sat�  urn V, which launched the spacecraft that carried humans to the Moon  (see Apollo), had three stages (see staged rocket). The U.S. space shuttle  system (from 1981) represents a significant departure from expendable  launch vehicles in that it is partially reusable�its manned orbiting com�  ponent is designed for numerous flights, and its solid rocket boosters can  be recovered and refurbished.</p><p>Laurana \lau-'ra-na\, Francesco (b. c. 1430, Vrana, Dalmatia, repub�  lic of Venice�d. before March 12,</p><p>1502, Avignon, Fr.) Italian sculptor  and medalist. His early life is  obscure. In 1453 he was commis�  sioned to work on the Castel Nuovo  in Naples. From 1461 to 1466 he was  in Provence at the court of the duke  of Anjou, for whom he executed a  series of medals. His other docu�  mented works include Madonnas  and bas-reliefs in Italy (chiefly Sic�  ily and Naples) and France, as well  as tombs and architectural sculptures  in France. He is best known for his  portrait busts of women, character�  ized by serene, detached dignity and  aristocratic elegance.</p><p>Laurasia Hypothetical former  supercontinent in the Southern  Hemisphere, which included modern  North America, Europe, and Asia  (except peninsular India). The con�  cept that the continents were at one  time joined was first set forth in  detail by Alfred Wegener in 1912. He  envisioned a single great landmass, Pangaea, which supposedly began to  separate in the Late Triassic Epoch (227-206 million years ago). Subse�  quent research distinguished between a northern landmass, Laurasia, and  Gondwana. Laurasia is thought to have fragmented into the present con�  tinents largely during the Mesozoic Era.

Laurel performed in circuses and vaudeville before settling in  the U.S. (1910), where he began appearing in silent movies. Hardy, son  of a Georgia lawyer, owned a movie house and acted in silent comedy  films from 1913. They joined Hal Roach�s studio in 1926 and began per�  forming together in early short films such as Putting Pants on Philip  (1927). They made more than 100 comedies, including Leave �em Laugh�  ing (1928), The Music Box (1932), Sons of the Desert (1933), and Way  Out West (1937), and are considered Hollywood�s first great comedy team.

Another genus, Cinnamomum,  includes the camphor tree and cinnamon. Also included in this family are  the AVOCADO, MOUNTAIN LAUREL, and SASSAFRAS.</p><p>Lauren, Ralph orig. Ralph Lifshitz (b. Oct. 14, 1939, New York,  N.Y., U.S.) U.S. fashion designer. Lauren grew up in the Bronx, in New  York City. While working for a tie company, he was inspired to begin  designing his own neckwear, and in 1967 he went into business for him�  self. From the inception of his brand, Lauren�s creations were character�  ized by a moneyed style that evoked the look of English aristocracy, as  adapted by the sporty, East-Coast American elite. His first menswear line  in 1968 featured classic tweed suits, and his first womens wear line in 1971  continued his explorations of classic tailoring and good taste, but with a  feminine twist. In 1972 Lauren debuted what would become his signature  piece: the mesh sport shirt, available in a variety of colours and featuring  his trademark emblem, the polo player. Throughout the following decades  he explored new ideas�including Southwestern themes and safari  looks�but maintained his central focus on classic American clothing. At  the turn of the 21st century, the presence of both his shops and his brand  name had become global.</p><p>Laurence, Margaret orig. Jean Margaret Wemyss (b. July 18,  1926, Neepawa, Man., Can.�d.

Mafic lavas, such as  basalt, form flows known by the Hawaiian names pahoehoe and aa.  Pahoehoe is smooth and gently undulating; the lava moves through natu�  ral pipes known as lava tubes. Aa is very rough, covered with a layer of  loose, irregular fragments called clinker, and flows in open channels. Lava  that starts out as pahoehoe may turn into aa as it cools. Lavas of interme�  diate composition form a block lava flow, which also has a top consisting  largely of loose rubble, but the fragments are fairly regular in shape,  mostly polygons with relatively smooth sides.

A Laval  reaction turbine attained a speed of 42,000 revolutions per minute. By  1896 he was operating a complete power plant using an initial steam  pressure of 3,400 lbs per sq in. He invented and developed the divergent  nozzle to deliver steam to the turbine blades.

In 1940, as min�  ister of state in Philippe Petain�s government (see Vichy France), he began  negotiations with the Germans on his own initiative, which aroused sus�  picion. Petain soon dismissed him, but in 1942 he returned as head of the  government.

Aug. 26, 1743,  Paris, France�d. May 8, 1794, Paris) French chemist, regarded as the  father of modern chemistry. His work on combustion, oxidation (see  oxidation-reduction), and GASes (especially those in air) overthrew the phlo�  giston doctrine, which held that a component of matter (phlogiston) was  given off by a substance in the process of combustion. That theory had  held sway for a century. He formulated the principle of the conservation  of mass (i.e., that the weights of the reactants must add up to the weights  of the products) in chemical reactions, clarified the distinction between ele�  ments and compounds, and was instrumental in devising the modern sys�  tem of chemical nomenclature (naming oxygen, hydrogen, and carbon).  He was among the first to use quantitative procedures in chemical inves�  tigations, and his experimental ingenuity, exact methods, and cogent rea�  soning, along with the resultant discoveries, revolutionized chemistry. He  also worked on physical problems, especially heat, and on fermentation,  respiration, and animals. Independently wealthy, he had a simultaneous  career as a public servant of remarkable versatility in areas including  finance, economics, agriculture, education, and social welfare. A reformer  and political liberal, he was active in the French Revolution but came under  increasing attack from extremists and was guillotined.</p><p>Lavrovsky \lav-Tof-ske\, Leonid (Mikhaylovich) (b.

The old�  est extant fragments of a law code are tablets from the ancient city of  Ebla dating to c. 2400 bc. The best-known ancient code is that of Ham�  murabi. Roman legal records began in the 5th century bc, though the first  formal codification, ordered by Justinian I, was not undertaken until the  6th century ad. In the Middle Ages and into the modern era, only local  or provincial compilations were attempted. The first major national code  was the Napoleonic Code, followed by the German, Swiss, and Japanese  codes. In common-law countries such as England and the U.S., law codes  have traditionally been less important than the record of judicial decisions,  though major codifications were completed in the U.S. in the 20th cen�  tury (e.g., the U.S. Code, the Uniform Commercial Code).

Henry became  the leading English songwriter of his time; some 435 of his songs survive.  His theatrical music includes that to John Milton�s masque Comus (1634).  William wrote a large quantity of instrumental music, mostly for string  consorts. His music for some 25 dramatic productions, including works by  Ben Jonson and William Davenant, made him the principal English theat�  rical composer before Henry Purcell.

Sept. 11, 1885, Eastwood, Not�  tinghamshire, Eng.�d. March 2, 1930, Vence, France) English novelist,  short-story writer, poet, and essayist. The son of a Midlands coal miner  and an educated mother, he began to write in 1905 and earned a teaching</p><p>certificate in 1908. Ford Madox Ford published much of Lawrence�s early  work in the English Review and helped place his first novel. The White  Peacock (1911). Lawrence often drew his themes from his own life and  relationships. Sons and Lovers (1913) is a clearly autobiographical novel  about working-class family life. In 1914 he married a German woman,  Frieda Weekley. The object of hostility and suspicion during World War  I because of his pacifism and her origins, the couple lived in various  countries after 1919, never returning to England. The Rainbow (1915) and  its sequel. Women in Love (1920), trace the sickness of modem civiliza�  tion to the effects of industrialization upon the human psyche. Kangaroo  (1923) describes the persecution he experienced during the war. The  Plumed Serpent (1926) was inspired by his fascination with Aztec cul�  ture. Lawrence�s writing is notable for its intensity and its erotic sensu�  ality; several of his works, including Lady Chatterley�s Lover (1928),  were banned as obscene.

In 1929 he developed the cyclotron, with which he  accelerated protons to speeds high enough to cause nuclear disintegra�  tion. He later produced radioactive isotopes for medical use, instituted the  use of neutron beams to treat cancer, and invented a colour-television pic�  ture tube. He worked with the Manhattan Project, converting the Berke�  ley cyclotron to separate uranium-235 by mass spectrometry. For his  invention of the cyclotron, he was awarded a 1939 Nobel Prize, and in  1957 he received the Enrico Fermi Award.

His best-known works are his series on historical and  social themes, such as Life in Harlem (1942) and War (1947). His later  works include a powerful series on the struggles of desegregation.

He studied at Oxford, submitting a thesis on Crusader castles. He learned  Arabic on an archaeological expedition (1911-14). During World War I  (1914-18) he conceived the plan of supporting Arab rebellion against the  Ottoman Empire as a way of undermining Germany�s eastern ally, and he  led Arab forces in a guerrilla campaign behind the lines, tying up many  Ottoman troops. In 1917 his forces had their first major victory, captur�  ing the port town of Al-'Aqabah. He was captured later that year, but he  escaped. His troops reached Damascus in 1918, but Arab factionalism and  Anglo-French decisions to divide the area into British- and French-  controlled mandates prevented the Arabs from forming a unified nation  despite their victory. Lawrence retired, declining royal decorations. Under  the name Ross, and later Shaw, he enlisted in the Royal Air Force (and  briefly the Royal Tank Corps). He finished his autobiography.

It occurs naturally for drooping black raspberry or forsythia  stems, whose trailing tips root where they come in contact with the soil.  They then send up new shoots from the newly rooted portion of the plant.  For soil layering, lower stems are bent to the ground and covered with  moist soil of good quality. For air layering, a branch is deeply slit and the  wound is covered with a ball of earth or moss and kept moist until roots  develop; the branch is then severed and transplanted. Layering was prac�  ticed by the ancient Egyptians and Greeks. See also cutting.</p><p>Lazarus In the New Testament, two apparently different people.

The principle, invaluable in the  chemical industry in developing the most efficient and profitable chemi�  cal processes, may be stated thus: A system at equilibrium, when subjected  to a perturbation, responds in a way that tends to minimize its effect.

Born in a  small Swiss town, he left home as a young man and developed many of  his ideas during his travels through Europe (1907-11). After settling in  Paris, Le Corbusier (his assumed name, from the surname of an ances�  tor) and the painter Amedee Ozenfant (1886-1966) formulated the ideas  of Purism, an aesthetic based on the pure, simple geometric forms of  everyday objects. His early work included theoretical plans for skyscraper  cities and mass-produced housing; in one of his many essays on archi�  tecture from the period, he declared that �a house is a machine for living  in.� Works from the 1920s such as the Villa Savoye at Poissy, France  (1929-30), with its structure raised on slender concrete pillars, open floor  plan, long strip windows, and roof terrace, established him as a major  proponent of the International Style. He and other architects working in  this style aspired to clean. Modernist lines, yet Le Corbusier was the first  architect to make a studied use of rough-cast concrete, a technique that  gave his work a distinctly sculptural, expressive quality. His later works  include the Unite d' Habitation and the lyrical chapel of Notre-Dame-du-  Haut at Ronchamp, France (1950-55). His government buildings at Chan�  digarh, India (begun 1950), with their enormous concrete sunshades,  sculptural facades, and swooping rooflines, represent the first large-scale  application of his city-planning principles.

The party emphasized  the threat to France posed by immigration, particularly of Arabs from  France�s former North African colonies. The party also opposed Euro�  pean integration, favoured the reintroduction of capital punishment, and  sought prohibitions on the building of additional mosques in France. Le  Pen ran several times for the presidency; though he captured less than 1%  of the vote in 1974, in 1988 and 1995 he won some 15%. In the presi�  dential election of 2002 Le Pen finished second in the first round of vot�  ing, winning 18%, though he was easily defeated in the second round by  Jacques Chirac.

In such areas rapid bacterial action  results in the absence of humus in the soil, because fallen plant material  is oxidized and the products are leached away.</p><p>Leacock, Stephen (Butler) (b. Dec. 30, 1869, Swanmore, Hamp�  shire, Eng.�d. March 28, 1944, Tor�  onto, Ont., Can.) British-born  Canadian writer and lecturer. He  immigrated to Canada with his par�  ents at age six. Though he taught  economics and political science at  McGill University (1903-36) and  wrote extensively on history and  political economy, his true calling  was humour. His fame rests on his  many books of lighthearted sketches  and essays, beginning with Literary  Lapses (1910) and Nonsense Novels  (1911). His humour is typically  based on a comic perception of  social foibles and the incongruity  between appearance and reality in  human conduct.</p><p>lead Metallic chemical element,  chemical symbol Pb, atomic number  82. Lead is a soft, silvery white or  grayish, malleable, ductile, dense metal that conducts electricity poorly.  Its stable isotopes are all end products of radioactive decay of uranium and  other heavy elements. Known since ancient times, lead is so durable and  resistant to corrosion that Roman lead pipes are still usable. Lead is used  in roofing, as cable coverings, and in pipes, conduits, and structures. Other  uses are in storage batteries, ammunition, and low-melting-point alloys  (e.g., solder, pewter) and as shielding against sound, vibrations, and radia�  tion. Lead is rarely found free in nature; its major ore is the sulfide GALENA  (PbS). Because it and its compounds are poisons (see lead poisoning),  lead-based paints and gasoline additives have been phased out in many  countries. Lead in compounds has valence 2 and 4; an oxide (litharge, PbO)  is the most widely used. Lead compounds are added to lead crystal (see  glass), glazes, and ceramics and are used as pigments, drying agents for  paints and varnishes, insecticides and herbicides, and fireproofing agents  and in matches, explosives, and pyrotechnics. Almost half of all lead is  recovered from recycled scrap. The �lead� in pencils is graphite.</p><p>lead-2 T 0 dating Method of dating that makes use of the ratio of the  amount of the radioactive isotope lead-210 to that of the stable isotope  lead-206. The method has been applied to the ores of uranium. Lead-210  dating is particularly useful for determining the ages of relatively recent  marine sediments and so has been applied to studies concerned with the  impact of human activity on the aquatic environment.</p><p>lead glance See galena</p><p>lead poisoning or plumbism Poisoning by accumulation of lead in  the body. Large doses cause gastroenteritis in adults and brain disorders  in children. Anemia, constipation and abdominal spasm, confusion, a pro�  gressive paralysis, and sometimes brain cancer result from chronic expo�  sure. Children are particularly susceptible to nerve and brain damage;  sensitive tests show that even low levels of lead can harm children and  are linked to behavioral problems. Sources in the home include lead-based  paint, lead drinking-water pipes, and lead-glazed tableware. Babies, who  put things in their mouths, are at highest risk. Working where lead is used  and exposure to some insecticides are other risk factors. The U.S. phase�  out of lead in gasoline was completed in 1996; similar bans are being  implemented worldwide. Treatment involves giving antidotes that bind  (see chelate) the lead in the tissues.</p><p>Leadbelly orig. Huddie William Ledbetter (b. c. Jan. 21, 1885?,  Mooringsport, La., U.S.�d. Dec. 6, 1949, New York, N.Y.) U.S. folk  blues singer and songwriter. As a child he learned to play many instru�  ments; he later worked as an itinerant musician with Blind Lemon Jef�  ferson. In 1918 he was imprisoned for murder; he was pardoned in 1925  by the governor of Texas, who had visited the prison and heard him sing.  Resuming a life of drifting, he was imprisoned for attempted murder in</p><p>1930; he was discovered in 1933 by folklorist John Lomax, who secured  his release. Under Lomax�s guidance he embarked on a concert tour, pub�  lished 48 songs with commentary about Depression-era conditions of  African Americans (1936), and recorded extensively. He worked with  Woody Guthrie in the group the Headline Singers. Leadbelly died penni�  less, but several of his songs, including �Goodnight, Irene,� �The Mid�  night Special,� and �Rock Island Line,� soon became standards.</p><p>leaf Any flattened, green outgrowth from the stem of a vascular plant.  Leaves manufacture oxygen and glucose, which nourishes and sustains  both plants and animals. Leaves and stem tissue grow from the same api�  cal bud. A typical leaf has a broad, expanded blade (lamina), attached to  the stem by a stalklike petiole. The leaf may be simple (a single blade),  compound (separate leaflets), or reduced to a spine or scale. The edge  (margin) may be smooth or jagged. Veins transport materials to and from  the leaf tissues, radiating from the petiole through the blade. They are  arranged in a netlike pattern in dicot leaves and are parallel in monocot  leaves (see cotyledon). The leafs outer layer (epidermis) protects the  interior (mesophyll), whose soft-walled, unspecialized green cells (paren�  chyma) produce carbohydrate food by photosynthesis. In autumn the green  chlorophyll pigments of deciduous leaves break down, revealing other  pigment colors (yellow to red), and the leaves drop off the tree. Leaf scars  that form during wound healing after the leaves drop are useful for iden�  tifying winter twigs. In conifers, evergreen needles, which are a type of  leaf, persist for two or three years.</p><p>Structures of a leaf. The epidermis is often covered with a waxy protective cuticle  that helps prevent water loss from inside the leaf. Oxygen, carbon dioxide, and  water enter and exit the leaf through pores (stomata) scattered mostly along the  lower epidermis. The stomata are opened and closed by the contraction and  expansion of surrounding guard cells. The vascular, or conducting, tissues are  known as xylem and phloem; water and minerals travel up to the leaves from the  roots through the xylem, and sugars made by photosynthesis are transported to  other parts of the plant through the phloem. Photosynthesis occurs within the  chloroplast-containing mesophyll layer.</p><p>� MERRIAM-WEBSTER INC.</p><p>leaf-footed bug See squash bug</p><p>leaf insect or walking leaf Any of about 25 species of flat green  insects (family Phylliidae) with a leaflike appearance. Leaf insects, which  range from India to the Fiji Islands, are about 2.3 in. (60 mm) long. The  female has large leathery forewings (tegmina) that lie edge to edge on the  abdomen and resemble, in their vein pattern, the midrib and veins in a  leaf. The hind wings have no function. The male has small tegmina and  ample, non-leaflike, functional hind wings. The newly hatched young are  reddish, but become green after feeding on leaves.</p><p>Leacock, photograph by Yousuf Karsh</p><p>� KARSH FROM RAPHO/PHOTO RESEARCHERS-EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1088 I leaf miner &#x25BA; learning</p><p>L_</p><p>N</p><p>leaf miner Any of various insect larvae that live and feed within a leaf,  including caterpillars, sawfly larvae, beetle and weevil grubs, and dipteran  maggots. Most leaf-miner burrows or tunnels are either thin, winding,  whitish trails or broad, whitish or brownish blotches. Though leaf miners  do not usually cause injury, they mar the appearance of ornamental trees  and shrubs. One method of control is to remove and bum infested leaves;  spraying with nicotine solutions or dusting with insecticides is effective  only when the adults are emerging.</p><p>leafhopper Any of the small, slender, often beautifully coloured and  marked sap-sucking insects of the  large family Cicadellidae. There is a  leafhopper species for almost every  type of plant. Most are less than 0.5  in. (12 mm) long. Leafhoppers can  be serious economic pests. Their  feeding may remove sap, destroy  chlorophyll, transmit disease, or curl  leaves; they also puncture the host  plant while laying eggs. Hopperburn  is a diseased condition caused by  their injection of a toxin into the  plant as they feed.</p><p>League of Arab States See</p><p>Arab League</p><p>League of Nations Organization for international cooperation estab�  lished by the Allied Powers at the end of World War I. A league covenant,  embodying the principles of collective security and providing for an  assembly, a council, and a secretariat, was formulated at the Paris Peace  Conference (1919) and contained in the Treaty of Versailles. The covenant  also set up a system of colonial mandates. Headquartered at Geneva, the  League was weakened by the failure of the U.S., which had not ratified the  Treaty of Versailles, to join the organization. Discredited by its failure to  prevent Japanese expansion in Manchuria and China, Italy�s conquest of  Ethiopia, and Germany�s seizure of Austria, the League ceased its activities  during World War II. It was replaced in 1946 by the United Nations.</p><p>Leahy \'la-he\, William D(aniel) (b. May 6, 1875, Hampton, Iowa,  U.S.�d. July 20, 1959, Bethesda, Md.) U.S. naval officer. After gradu�  ating from the U.S. Naval Academy, he served in the Spanish-American  War, the Philippine insurrection, and the Boxer Rebellion. He commanded  a navy transport during World War I, when he began a friendship with  Franklin D. Roosevelt, then assistant secretary of the navy. He served as  chief of naval operations (1937-39), as governor of Puerto Rico (1939),  and as U.S. ambassador to France (1940). He was Roosevelt�s chief of  staff during World War II and continued in that post under Harry S. Tru�  man.

Louis S.B. Leakey (b. 1903�d. 1972), born of British missionary  parents, grew up in Kenya, was educated at Cambridge University, and  eventually (1931) began field research at Olduvai Gorge in Tanzania. He  was joined there by his wife, Mary D. Leakey (b. 1913�d. 1996), who in  1959 uncovered remains of a form of Australopithecus. The couple later  uncovered the first known remains of Homo habilis, as well as those of Ken-  yapithecus, a possible common ancestor of humans and apes that lived c.  14 million years ago. L.S.B. Leakey commissioned Jane Goodall, Birute  Galdikas, and Dian Fossey to undertake pioneering studies of chimpanzees,  orangutans, and gorillas, respectively. Mary Leakey continued to make  important discoveries, including the Laetoli footprints, after her husband�s  death. Their son, Richard Leakey (b. 1944), is known for his work at the  Koobi Fora site on the shores of Lake Turkana in Kenya, where he uncovered  evidence of H. habilis dated as early as 2.5 million years ago. His wife,  zoologist Meave Leakey (b. 1942), discovered two new hominin species.</p><p>Leal, Juan de Valdes See Juan de Valdes Leal</p><p>Lean, Sir David (b. March 25, 1908, Croydon, Surrey, Eng.�d.

Begun in 1173 as  the third and final structure of the city�s cathedral complex, it was  designed to stand 185 ft (56 m) high. Work was suspended several times  as engineers sought solutions; the tower, still leaning, was completed in  the 14th century. Subsiding at the rate of 0.03 in (1.2 mm) a year, the  structure was in danger of collapse, and in 1990 it was closed as engi�  neers undertook a strengthening project that decreased the lean by 17 in  (44 cm) to about 13.5 ft (4.1 m).

In 1963 Lear formed  Lear Jet, Inc., which produced small private and corporate jet aircraft. In  1964 he developed the stereo eight-track player for automobiles.</p><p>learned helplessness In psychology, a mental state in which a labo�  ratory subject forced to bear aversive stimuli becomes unable or unwill�  ing to avoid subsequent applications, even if they are �escapable,�  presumably through having learned that situational control is generally  out of one�s hands. Experiments, first on dogs and later on humans, led  some researchers, including Martin E.P. Seligman (b. 1942) in Helpless�  ness (1975), to believe that chronic failure, depression, and similar con�  ditions are forms of learned helplessness. Critics have argued that different  conclusions can be drawn from such tests and that broad generalizations  are unwarranted.</p><p>learning Process of acquiring modifications in existing knowledge,  skills, habits, or tendencies through experience, practice, or exercise.  Learning includes associative processes (see association; conditioning),  discrimination of sense-data, psychomotor and perceptual learning (see per�  ception), imitation, concept formation, problem solving, and insight learning.  Animal learning has been studied by ethologists and comparative psy�  chologists, the latter often drawing explicit parallels to human learning (see  comparative psychology; ethology).

More recently, cognitive  scientists have explored learning as a form of information processing, while  some brain researchers, such as Gerald Maurice Edelman, have proposed  that thinking and learning involve an ongoing process of cerebral pathway  building.

Though their causes and nature are still not fully understood, it is widely  agreed that the presence of a learning disability does not indicate subnor�  mal intelligence. Rather it is thought that the learning-disabled have a  neurologically based difficulty in processing language or figures, which  must be compensated for with special learning strategies or with extra  effort and tutoring. Examples of learning disabilities include difficulty in  reading (dyslexia), writing (dysgraphia), and mathematics (dyscalcula).  Learning disabilities may be diagnosed through testing, and children may  be enrolled in programs offering special help; left unrecognized, learning  disabilities may result not only in poor classroom performance but also  in low self-esteem and disruptive behaviour.</p><p>least squares method Statistical method for finding a line or  curve�the line of best fit�that best represents a correspondence between  two measured quantities (e.g., height and weight of a group of college  students).

The method uses calculus techniques to  find the minimum of the sum of the squares of the vertical distances of each  data point from the proposed line. More generally, the process is called  regression or, when the fitted curve is a line, linear regression.</p><p>leather Animal skins and hides treated to preserve them and make them  suitable for use.

In 1975 Lebanon�s Muslims and leftists sup�  ported the PLO and sought more political power; its Christians, seeking  to maintain their political dominance, opposed the PLO. The factions  fought fiercely through early 1976, and Lebanon became effectively par�  titioned, with the Christians in power in the north and the Muslims in the  south. Fearing an expanded war, both Israel and Syria intervened on the  side of the Christians, who had begun to lose ground. Fighting continued  at a lower level of intensity until 1982, when Israel invaded southern  Lebanon to destroy Palestinian guerrilla bases; PLO forces were driven  out of Beirut, and by 1985 Israel had withdrawn from most of Lebanon,  which by then was split internally over whether to accept Syria�s lead�  ership. In 1989 the Christian leader General Michel Aoun attempted to  drive Syria from Lebanon but was defeated, and the Arab League medi�  ated a peace deal; his removal from power in 1990 eliminated the largest  obstacle to implementing a 1989 peace accord. In southern Lebanon,  fighting between Israeli and Hezbollah forces continued even after Israel�s  final withdrawal from Lebanese territory in 2000.</p><p>Lebanese National Pact Power-sharing arrangement established in  1943 between Lebanese Christians and Muslims whereby the president is  always a Christian and the prime minister a Sunnite Muslim.

Languages: Arabic (official),</p><p>French, English. Religions: Islam, Chris�  tianity, Druze. Currency: Lebanese pound.</p><p>Uplands include the Lebanon Mountains in the central region and the  Anti-Lebanon and Hermon ranges along the eastern border; a low coastal  plain stretches along the Mediterranean. The Litani River flows southward  through the fertile AI-Biqa* (Beqaa) valley region. Originally, much of the  country was forested�the cedars of Lebanon were famous in antiquity�  but woodlands now cover only a tiny fraction of the country. Lebanon is  not agriculturally self-sufficient and must rely on food imports. Its tradi�  tional role as the financial centre of the Middle East has been undermined  since the outbreak of the Lebanese civil war (1975-76). It is a republic with  one legislative house; its chief of state is the president, and the head of  government is the prime minister. Much of present-day Lebanon corre�  sponds to ancient Phoenicia, which was settled c. 3000 bc. In the 6th cen�  tury ad, Christians fleeing Syrian persecution settled in northern Lebanon  and founded the Maronite Church. Arab tribal peoples settled in southern  Lebanon, and by the 11th century religious refugees from Egypt had  founded the Druze faith. Part of the medieval Crusader states, Lebanon  was later ruled by the Mamluk dynasty. In 1516 the Ottoman Empire  seized control; the Ottomans, who first ruled by proxy, ended the local  rule of the Druze Shihab princes in 1842. Deteriorating relations between  religious groups resulted in the massacre of Maronites by Druze in 1860.  France intervened, forcing the Ottomans to form an autonomous province  for an area known as Mount Lebanon under a Christian governor. Fol�  lowing World War I (1914-18), the whole of Lebanon was administered  by the French military as part of a French mandate; the country was fully  independent by 1946. After the Arab-Israeli war of 1948-49, tens of thou�  sands of Palestinian refugees settled in southern Lebanon. In 1970 the  Palestine Liberation Organization (PLO) moved its headquarters to Leba�  non and began raids into northern Israel. The Christian-dominated Leba�  nese government tried to curb them, and in response the PLO sided with  Lebanon�s Muslims in their conflict with Christians, fueling the descent</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1090 I Lebanon Mountains &#x25BA; Lee</p><p>L_</p><p>N</p><p>into a civil war that split the country into numerous political and religious  factions. In 1976-82 Syrian and UN troops tried to maintain a cease-fire.  In 1982 Israeli forces invaded in an effort to drive Palestinian forces out  of southern Lebanon; Israeli troops withdrew from all but a narrow buffer  zone in the south by 1985. Thereafter, guerrillas from the Lebanese Shfite  militia Hezbollah clashed with Israeli troops regularly.

In the mid 1770s he planned a new saltworks and surround�  ing town at the Salines de Chaux, Arc-et-Senans; the design, in which  rings of workers� dwellings enclosed a central factory, was designed both  to facilitate production and ensure healthy conditions for the workers. His  theatre at Besangon (1771-73) was revolutionary in its provision of seats  for the general public as well as the upper classes. The elaborate barrieres  (tollhouses) he designed for Paris (1785-89) were ruinously expensive,  and Ledoux was removed from the project. Arrested during the French  Revolution, he did not practice architecture after his release.</p><p>Ledru-Rollin Uo-'driE-ro-TaA, Alexandre-Auguste (b. Feb. 2,  1807, Paris, France�d. Dec. 31, 1874, Fontenay-aux-Roses) French radi�  cal politician. He was elected to the Chamber of Deputies in 1839, but  his insistence on the need for a republican government isolated him from  other leftists. Following the February Revolution, through his influence as  minister of the interior in the provisional government (1848), elections  for a new legislature were held for the first time under universal manhood  suffrage. In 1849 he demanded the impeachment of Louis-Napoleon (later  Napoleon III) and led an unsuccessful insurrection. He fled to England but  returned to France after the amnesty of 1870.</p><p>Lee, Ann (b. Feb. 29, 1736, Manchester, Eng.�d. Sept. 8, 1784, Water-  vliet, N.Y., U.S.) British-American religious leader. A factory worker in  her youth in Manchester, she joined the Shakers in 1758 and was acknowl�  edged as their leader in 1770. Persecuted by the English authorities and  compelled by what she believed was a vision, she immigrated to America  in 1774. With a band of followers, she founded a settlement at Niskeyuna  (present-day Watervliet), N.Y., in 1776, and thereafter her movement  spread rapidly. Mother Ann, as she came to be known, was said to have  performed miracles, including healing the sick by touch. She was impris�  oned briefly for treason because of her pacifist doctrines and refusal to  sign an oath of allegiance.</p><p>Lee, Bruce orig. Lee Yuen Kam (b. Nov. 27, 1940, San Francisco,  Calif., U.S.�d. July 20, 1973, Hong Kong) U.S. film actor. The son of a  touring Chinese opera star, he spent  his childhood in Hong Kong, where  he acted in several movies. He  returned to the U.S., and in 1966 he  landed a role in the television series  The Green Hornet. In the early 1970s  he became a popular star of martial-  arts action films, including Fist of  Fury (1972) and Enter the Dragon  (1973), which gained an interna�  tional cult following. His career was  cut short by his sudden death at 33  from a brain edema suffered after  taking a pain killer. Nevertheless, his  films remained popular and became  widely imitated. His son Brandon  Lee (1965-93) was emerging as an  action-movie star when he died in a  shooting accident on a movie set.</p><p>Lee, Gypsy Rose orig. Rose  Louise Hovick (b.

An editor helped her  transform a series of short stories into the novel To Kill a Mockingbird  (1960). Lee�s only novel, it was nationally acclaimed, winning a Pulitzer  Prize in 1961, and was adapted into a memorable film in 1962. The novel�s  hero is the white lawyer Atticus Finch, whose just and compassionate acts  include an unpopular defense of a black man falsely accused of raping a  white girl. The book continued to resonate into the 21st century.</p><p>Lee, Henry (b. Jan. 29, 1756, Prince William county, Va.�d.

In the American Revolution he rose to cavalry commander (earning the nick�  name �Light-Horse Harry�) and led victories at Paulus Hook, N.J., and in  the South. As governor of Virginia (1791-94), he commanded the army that  suppressed the Whiskey Rebellion (1794). In the U.S. House of Representa�  tives (1799-1801), he wrote the resolution eulogizing George Washington  as �first in war, first in peace, and first in the hearts of his countrymen.�  After 1800 Lee failed in several land and financial speculations and was  twice imprisoned for debt. He was the father of Robert E. Lee.</p><p>Lee, Ivy Ledbetter (b. July 16, 1877, Cedartown, Ga., U.S.�d. Nov.  9, 1934, New York, N.Y.) U.S. public relations pioneer. He worked as a  newspaper reporter before becoming press representative for a group of  coal miners in 1906 and for the Pennsylvania Railroad Co. in 1912. His  success in improving their public images brought him many powerful cli�  ents, including the Rockefeller interests. His greatest innovation was his  frankness with the press, which he took care to notify of newsworthy  developments at the companies he represented.</p><p>Lee, Peggy orig. Norma Deloris Egstrom (b.

Singing with a group in Chicago, she was engaged by Benny Goodman  as his principal singer in 1941. She began singing on her own in 1943 and  also began collaborating on songs, often with her husband, Dave Barbour,  including �Fever,� �Manana,� and several songs for Walt Disney�s Lady  and the Tramp (1955). With her smooth, lightly husky voice, usually  backed by jazz-influenced arrangements, she produced other hits such as  �Lover� and �Is That All There Is?�</p><p>Lee, Richard Henry (b. Jan. 20, 1732, Stratford, Va.�d. June 19,  1794, Chantilly, Va., U.S.) U.S. statesman. As a member of the Virginia  House of Burgesses (1758-75), he opposed the Stamp Act and the Town-  shend Acts. He helped initiate the Committees of Correspondence and was  active in the First and Second Continental Congress. On June 7, 1776, he  introduced a resolution calling for independence from Britain. Its adoption  led to the Declaration of Independence, which he signed, as he did the  Articles of Confederation. He again served in Congress from 1784 to 1787,  acting as its president in 1784. He opposed ratification of the Constitution</p><p>of the United States because it lacked a  bill of rights. He later served in the  first U.S. Senate (1789-92).</p><p>Lee, Robert E(dward) (b. Jan.  19, 1807, Stratford, Westmoreland  county, Va., U.S.�d. Oct. 12, 1870,  Lexington, Va.) U.S. and Confeder�  ate military leader. He was the son of  Henry Lee. After graduating from  West Point, he served in the engi�  neering corps and in the Mexican  War under Winfield Scon. He trans�  ferred to the cavalry in 1855 and  commanded frontier forces in Texas  (1856-57). In 1859 he led U.S.  troops against the slave insurrection  attempted by John Brown at Harpers  Ferry. In 1861 he was offered com�  mand of a new army being formed</p><p>Robert E. Lee, 1865.</p><p>LIBRARY OF CONGRESS, WASHINGTON, D.C.</p><p>to force the seceded Southern states back into the Union. Though opposed  to secession, he refused. After his home state of Virginia seceded, he  became commander of Virginia�s forces in the American Civil War and  adviser to Jefferson Davis, president of the Confederacy. Taking command  of the Army of Northern Virginia (1862) after Joseph Johnston was  wounded, Lee repulsed the Union forces in the Seven Days' Battles. He  won victories at Bull Run, Fredericksburg, and Chancellorsville. His attempts  to draw Union forces out of Virginia by invading the North resulted in  failures at Antietam and Gettysburg. In 1864-65 he conducted defensive  campaigns against Union forces under Ulysses S. Grant that caused heavy  Union casualties. Lee ended his retreat behind fortifications built at Peters�  burg and Richmond (see Petersburg Campaign). By April 1865 dwindling  forces and supplies forced Lee, now general of all Confederate armies,  to surrender at Appomattox Court House. After several months of recu�  peration, he accepted the post of president of Washington College (later  Washington and Lee University), where he served until his death.</p><p>Lee, Spike orig. Shelton Jackson Lee (b. March 20, 1957, Atlanta,  Ga., U.S.) U.S. film director. He grew up in Brooklyn, N.Y., and earned a  master�s degree in film at New York University. The comedy She�s Gotta  Have It (l 986) brought him attention, but it was Do the Right Thing (1989),  a portrait of racial tensions in Brooklyn, that brought him widespread  acclaim. Many of his films focused on aspects of African American life,  including School Daze (1988), Jungle Fever( 1991), Crooklyn (1994), and  He Got Game (1998). The epic Malcolm X (1992) and the documentary  Four Little Girls (1997) showed Lee�s versatility as a director.</p><p>Lee, William (b. 1550?, Calverton, Nottinghamshire, Eng.�d. 1610?,  Paris, France) British inventor of the first knitting machine.

He  worked as a legal adviser to labour  unions and won election to Sin�  gapore�s legislative council in 1955,  while the country was still a British  crown colony. He helped Singapore  achieve self-government and, run�  ning as an anticolonialist and anti�  communist, was elected prime  minister in 1959. His numerous  reforms included the emancipation  of women. He briefly entered Sin�  gapore in the Federation of Malaysia  (1963-65); on its withdrawal, Sin�  gapore became a sovereign state.

Leaves of many members appear feathery, and  flowers are almost universally showy. In economic importance, this order  is surpassed only by the grass and sedge order (Cyperales). In the pro�  duction of food, the legume family is the most important of any family.  The pods are part of the diet of nearly all humans and supply most dietary  protein in regions of high population density. In addition, legumes per�  form the invaluable act of nitrogen fixation. Because they contain many  of the essential amino acids, legume seeds can balance the deficiencies of  cereal protein. Legumes also provide edible oils, gums, fibers, and raw  material for plastics, and some are ornamentals.

In the 1890s he was a military bandmaster like  his father; by the end of the decade he had moved to Vienna, where he</p><p>became a popular composer of marches and waltzes. After 1901 he con�  centrated on orchestra conducting and on composing, notably his 40 witty  and melodic operettas that embody the prewar Viennese spirit, including  the popular The Merry Widow (1905), The Countess of Luxembourg  (1909), and The Land of Smiles (1929).</p><p>Lehmbruck Vlam-briik\, Wilhelm (b.

In 1950,  while still in their teens, Leiber and Stoller became a songwriting and  production team, among the first to produce recordings that combined pop  music with rhythm and blues. Their first successful collaboration came with  �Hound Dog,� recorded by Big Mama Thornton (1952) and later by Elvis  Presley, who would record more than 20 of their songs. They wrote numer�  ous songs for the Coasters, including �Yakety Yak.� Other hits include  �There Goes My Baby,� �Stand by Me,� and �Love Potion Number Nine.�  Their songs were recorded by the Beatles, Aretha Franklin, James Brown,  and Ben E.

Nov. 14, 1716, Hannover, Hanover) German philosopher, mathematician,  inventor, jurist, historian, diplomat, and political adviser. He obtained a  doctorate in law at age 20. In 1667 he began working for the elector of  Mainz, in which position he codified the laws of the city, among other  important tasks. He served the dukes of Braunschweig-Luneburg as librar�  ian and councillor (1676-1716). In 1700 he helped found the German  Academy of Sciences in Berlin and became its first president. Though he  wrote voluminously, he published little during his lifetime. In metaphys�  ics he is known for his doctrine of the monad, according to which reality  is ultimately constituted of simple substances (monads), each consisting  of nothing but perception and appetite. Though each state of a monad is  the cause of its succeeding state and the effect of its preceding one, there  are no causal relations between monads; the appearance of causal rela�  tions between substances is accounted for by the supposition of a �pre-  established harmony� between the perceptual states of different monads.  His principle of the identity of indiscemibles states that an individual x  and an individual y are identical if and only if they share all the same  intrinsic, non-relational properties. His Theodicy (1710) sought to recon�  cile the goodness of God with the existence of evil in the world by assert�  ing that only God is perfect and that the actual world is the �best of all  possible worlds.� This view was famously mocked by Voltaire in his  comic novel Candide. In mathematics, Leibniz explored the idea of a uni�  versal mathematical-logical language based on the binary number system  (De arte combinatoria [1666]), though all the calculating devices that he  later built used the decimal system. He discovered the fundamental theo�  rem of calculus independently of Isaac Newton; the acrimonious dispute  over priority left England mathematically backward for more than a gen�  eration before Leibniz�s superior notation and methods were adopted. He  also made important contributions to optics and mechanics. He is con�  sidered the last great polymath of Western civilization.</p><p>Leibovitz, Annie orig. Anna-Lou Leibovitz (b.

Handsome and ambitious, he won Elizabeth�s  affection upon her accession (1558) and was made a privy councillor in  1559. When his wife died in 1560, it was rumoured that he had murdered  her in order to marry Elizabeth. He became an active suitor of Elizabeth;  though he failed to win the queen�s hand, they remained close friends.

April  22, 1870, Simbirsk, Russia�d. Jan. 21, 1924, Gorki, near Moscow)  Founder of the Russian Communist Party, leader of the Russian Revolu�  tion of 1917, and architect and builder of the Soviet state. Born to a  middle-class family, he was strongly influenced by his eldest brother,  Aleksandr, who was hanged in 1887 for conspiring to assassinate the tsar.  He studied law and became a Marxist in 1889 while practicing law. He  was arrested as a subversive in 1895 and exiled to Siberia, where he mar�  ried Nadezhda Krupskaya. They lived in western Europe after 1900. At the  1903 meeting in London of the Russian Social-Democratic Workers' Party,  he emerged as the leader of the Bolshevik faction. In several revolution�  ary newspapers that he founded and edited, he put forth his theory of the  party as the vanguard of the proletariat, a centralized body organized  around a core of professional revolutionaries; his ideas, later known as  Leninism, would be joined with Karl Marx�s theories to form Marxism-  Leninism, which became the communist worldview. With the outbreak of  the Russian Revolution of 1905, he returned to Russia, but he resumed his  exile in 1907 and continued his energetic agitation for the next 10 years.  He saw World War I as an opportunity to turn a war of nations into a war  of classes, and he returned to Russia with the Russian Revolution of 1917  to lead the Bolshevik coup that overthrew the provisional government of  Aleksandr Kerensky. As revolutionary dictator of the Soviet state, he signed  the Treaty of Brest-Litovsk with Germany (1918) and repulsed counter�  revolutionary threats in the Russian Civil War. He founded the Comintern  in 1919. His policy of War Communism prevailed until 1921, and to fore�  stall economic disaster he launched the New Economic Policy. In ill health  from 1922, he died of a stroke in 1924.</p><p>Leningrad See Saint Petersburg</p><p>Leningrad, Siege of (Sept. 8, 1941-Jan. 27, 1944) Prolonged siege  of the city of Leningrad (now St. Petersburg) by German forces in World  War II. German forces invaded the Soviet Union in June 1941 and  approached Leningrad from the west and south while Germany�s Finnish  allies came from the north. By November 1941 the city was almost com�  pletely encircled and its supply lines to the Soviet interior cut off. In 1942  alone, in excess of 650,000 of Leningrad�s citizens died from starvation,  disease, and shelling from distant German artillery. Sparse food and fuel  supplies reached the city by barge in the summer and by sled in winter  across Lake Ladoga. The supplies kept the city�s arms factories operat�  ing and its two million inhabitants barely alive, while another one mil�  lion children and sick and elderly people were evacuated. Soviet  offensives in 1943 partially broke the German encirclement and were fol�  lowed in January 1944 by a successful Soviet attack that drove the Ger�  mans westward from the city�s outskirts, ending the siege.</p><p>Leninism Principles expounded by Vladimir Ilich Lenin to guide the tran�  sition of society from capitalism to communism. The tenets of Marxism,  which Lenin embraced, provided no concrete guidelines for the transi�  tion. Lenin believed that a small, disciplined, professional group of revo�  lutionaries was needed to violently overthrow the capitalist system, and  that a �dictatorship of the proletariat� must guide society until the day  when the state would wither away. That day never came, and Leninism  in practice meant state control of all aspects of life by the Communist Party  and the creation of the first modern totalitarian state.

Their political activism and social ideals were reflected in much of  Lennon�s early solo work, including the hit �Imagine,� and attracted the  attention of the U.S. government, which sought to have him deported. After  1975 he withdrew from public life; he and Ono returned with the album  Double Fantasy shortly before his murder by a deranged fan.

Because of the curvature of its surface, different rays of light are  refracted (see refraction) through different angles. A convex lens causes  rays to converge on a single point, the focal point. A concave lens causes  rays to diverge as though they are coming from a focal point. Both types  cause the rays to form a visual image of the object.

After Weill�s death, she lent her inimitably  husky voice to revivals throughout the 1950s, including a long-running  production of The Threepenny Opera, and she later performed in Brecht  on Brecht (1962), Mother Courage and Her Children (1965), and Caba�  ret (1966), as well as in films.</p><p>Leo (Latin: �Lion�) In astronomy, the constellation lying between Can�  cer and Virgo; in astrology, the fifth sign of the zodiac, governing approxi�  mately the period July 23-August 22. Its symbol, a lion, has been  associated with the Nemean lion slain by Heracles. The Nemean lion was  considered invulnerable because its skin was impervious to arrows, but  Heracles battered it to death with a club. Zeus put the lion in the sky as a  constellation.</p><p>Leo I, Saint known as Leo the Great (b. 4th century, Tuscany?�d.  Nov. 10, 461, Rome; Western feast day November 10, Eastern feast day  February 18) Pope (440-461). He was a champion of orthodoxy and a Doc�  tor of the Church. When the monk Eutyches of Constantinople asserted that  Jesus Christ had only a single divine nature, Leo wrote the Tome, which  established the coexistence of Christ�s human and divine natures. Leo�s  teachings were embraced by the Council of Chalcedon (451), which also  accepted his teaching as the �voice of Peter.� Leo dealt capably with the  invasions of barbaric tribes, persuading the Huns not to attack Rome (452)</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Leo III &#x25BA; Leoncavallo I 1097</p><p>and the Vandals not to sack the city (455). Leo was also an exponent of the  precept of papal primacy, and his personal example and letters and sermons  contributed greatly to the growth of papal authority.</p><p>Leo III known as Leo the I saurian \I-'sor-e-3n\ (b. c. 675, Germanicia,  Commagene, Syria�d. June 18, 742, Constantinople) Byzantine emperor  (717-41), founder of the Isaurian dynasty. A high-ranking military com�  mander, he seized the throne with the help of Arab armies who hoped to  subjugate the Byzantine Empire. He then successfully defended Constan�  tinople against the Arabs (717-718). Having crowned his son Constantine  V coemperor (720), Leo used his son�s marriage to cement an alliance with  the Khazars. Victory over the Arabs at Akroi'nos (740) was crucial in pre�  venting their conquest of Asia Minor. Leo issued an important legal code,  the Ecloga (726). His policy of iconoclasm (730), which banned the use of  sacred images in churches, engendered a century of conflict within the  empire and further strained relations with the pope in Rome.</p><p>Leo IX, Saint orig. Bruno, count von Egisheim und Dags-  burg (b. 1002, Egisheim, Alsace, Upper Lorraine�d. April 19, 1054,  Rome; feast day April 19) Pope (1049-54). He was consecrated bishop  of Toul in 1027. He was named pope by Emperor Henry III but insisted  on election by the clergy and people of Rome. His efforts to strengthen  the papacy and eradicate clerical marriage and simony laid the foundation  for the Gregorian reform movement. His assertion of papal primacy and  his military campaign against the Normans in Sicily (1053) alienated the  Eastern church. His representatives excommunicated the patriarch of Con�  stantinople. Though Leo had already died, their act triggered the Schism  of 1054.</p><p>Leo X orig. Giovanni de' Medici (b. Dec. 1, 1475, Florence�d.  Dec. 1, 1521, Rome) Pope (1513-21), one of the most extravagant of the  Renaissance pontiffs. The second son of Lorenzo de' Medici, he was edu�  cated at his father�s court in Florence and at the University of Pisa. He  was named a cardinal in 1492, and in 1494 he was exiled from Florence  by the revolt of Girolamo Savonarola. He returned in 1500 and soon con�  solidated Medici control of the city. As pope, he became a patron of the  arts, accelerating construction of St. Peter's Basilica. He strengthened the  papacy�s political power in Europe, but his lavish spending depleted his  treasury. He discouraged reforms at the fifth Lateran Council, and he  responded inadequately to the Reformation, excommunicating Martin  Luther in 1521 and failing to address the need for change, a lapse that  signaled the end of the unified Western church.</p><p>Leo XIII orig. Vincenzo Gioacchino Pecci (b. March 2, 1810,  Carpineto Romano, Papal States�d.</p><p>July 20, 1903, Rome) Pope (1878�</p><p>1903). Bom into the Italian nobility,  he was ordained a priest in 1837 and  entered the diplomatic service of the  Papal States. He was appointed  bishop of Perugia in 1846 and was  named a cardinal in 1853. He was  elected pope in 1878, and, despite his  advanced age and frail health, he  directed the church for a quarter of a  century. Like his predecessor, Pius IX,  he opposed Freemasonry and secular  liberalism, but he brought a new  spirit to the papacy by adopting a  conciliatory attitude toward civil  governments and taking a more posi�  tive view of scientific progress.</p><p>Leochares \le-'a-k9-,rez\ (fl. 4th  century bc, Greece) Greek sculptor to  whom the Apollo Belvedere is often  attributed. He worked for Philip II of Macedonia and his son, Alexander the  Great, and was commissioned to produce gold and ivory statues of the  royal family. He is said to have worked with Scopas on the Mausoleum at  Halicarnassus, one of the Seven Wonders of the World, c. 350 bc.</p><p>Leon \la-'on\ City (pop., 2001: 130,916), northwestern Spain. The city  began as the camp of a Roman legion; its name is derived from the Latin  legio. Held by the Goths during the 6th and 7th centuries, it then fell to  the Moors, who ruled it until 850. In the 10th century, it became the capi�  tal of the kingdom of Leon. An industrial as well as a tourist centre, its  site includes medieval churches.</p><p>Leon City (pop., 1995: 123,865), western Nicaragua. The second largest  city in Nicaragua, it is the country�s political and intellectual centre. It  was founded by the Spanish on the edge of Lake Managua in 1524; it was  later destroyed by an earthquake and rebuilt in 1610 near the Pacific coast,  northwest of Managua. Leon was the capital of Nicaragua until 1855. It  has had a long political and commercial rivalry with the city of Granada.  It is the burial place of poet and diplomat Ruben Dario and the seat of the  University of Leon.</p><p>Leon Medieval kingdom, northwestern Spain. Leon proper included the  cities of Leon, Salamanca, and Zamora�the adjacent areas of Vallodolid  and Palencia being disputed with Castile, originally its eastern frontier. It  began as a Christian kingdom in the early 10th century when Garcia I  established his court on a former Roman legion campsite. Its rulers lost  ground to the Moors during the 10th century but reconquered much ter�  ritory in the 11th century. From 1037 to 1157 it was united with the king�  dom of Castile, but it then regained its independence and was ruled by  its own kings. It was permanently reunited with Castile in 1230. The  modern autonomous community of Castile-Leon covers roughly the same  area.</p><p>Leon, Arthur Saint- See Arthur Saint-Leon</p><p>Leonard, Buck orig. Walter Fenner Leonard (b.

With his teammate Josh Gibson, he led the Homestead  Grays to nine consecutive championships from 1937 through 1945.  Known as a formidable home-run hitter and an outstanding first baseman,  he was selected to the Negro leagues� East-West All-Star game a record  11 times.</p><p>Leonard, Sugar Ray orig. Ray Charles Leonard (b. May 17,</p><p>1956, Rocky Mount, N.C., U.S.) U.S. welterweight and middleweight  boxer. Leonard was an outstanding amateur, winning 145 of 150 bouts,  including a 1976 Olympic championship. He turned professional in 1977  and gained the world welterweight title in 1979 by defeating Wilfred  Benitez. He lost the title to Roberto Duran in 1980 but recaptured it from  him later that year. He retired in the early 1980s with a detached retina  but made a comeback in 1984. In 1987 he went into the ring as a middle�  weight to defeat Marvin Hagler in one of boxing�s great matches. He  retired again in 1991. He was resoundingly defeated in a final comeback  attempt in 1997. Known for his agility and finesse, he won 36 of his 39  professional matches. He later became a television commentator.</p><p>Leonardo da Vinci \'vin-che\ (b. April 15, 1452, Anchiano, Republic  of Florence�d. May 2, 1519, Cloux, France) Italian Renaissance painter,  sculptor, draftsman, architect, engineer, and scientist. The son of a land-  owner and a peasant, he received training in painting, sculpture, and  mechanical arts as an apprentice to Andrea del Verrocchio. In 1482, hav�  ing made a name for himself in Florence, he entered the service of the  duke of Milan as �painter and engineer.� In Milan his artistic and creative  genius unfolded. About 1490 he began his project of writing treatises on  the �science of painting,� architecture, mechanics, and anatomy. His theo�  ries were based on the belief that the painter, with his powers of percep�  tion and ability to pictorialize his observations, was uniquely qualified to  probe nature�s secrets. His numerous surviving manuscripts are noted for  being written in a backward script that requires a mirror to be read. In  1502-03, as military architect and engineer for Cesare Borgia, he helped  lay the groundwork for modern cartography. After five years of painting  and scientific study back in Florence (1503-08), he returned to Milan,  where his scientific work flourished. In 1516, after an interlude under  Medici patronage in Rome, he entered the service of Francis I of France;  he never returned to Italy. Though only some 17 completed paintings sur�  vive, they are universally seen as masterpieces. The power of The Last  Supper (1495-97) comes in part from its masterly composition. In the  Mona Lisa (c. 1503-06) the features and symbolic overtones of the sub�  ject achieve a complete synthesis. The unique fame that Leonardo enjoyed  in his lifetime and that, filtered by historical criticism, has remained  undimmed to the present day rests largely on his unlimited desire for  knowledge, a trait that guided all his thinking and behaviour.</p><p>Leoncavallo \la-,on-ka- , val-lo\ / Ruggero (b.

Giacomo Puccini�s rejection of Leoncavallo�s help with Manon Lescaut  and Ricordi�s rejection of his own projects caused him in anger to write  the verismo one-act opera Pagliacci (1892) for Ricordi�s rival. Though  he wrote several other operas and operettas, Pagliacci was his only endur�  ing success.</p><p>Leone \la-'o-na\, Sergio (b. Jan. 3, 1929?, Rome, Italy�d. April 30,  1989, Rome) Italian film director. After working as an assistant to Italian  and U.S. directors, he made his directing debut with The Colossus of  Rhodes (1961). He won a wide audience with A Fistful of Dollars (1964),  the first of the violent Italian-made �spaghetti westerns�; the equally  popular For a Few Dollars More (1965) and The Good, the Bad, and the  Ugly (1966) also starred Cunt Eastwood. Among his other films are the  epics Once upon a Time in the West (1968) and Once upon a Time in  America (1984). Many of his films were at first poorly received by crit�  ics, but Leone was eventually recognized for his meticulous care for his�  torical accuracy and his powerful sense of visual composition.</p><p>Leonidas Ue-'a-no-dosX (d. 480 bc, Thermopylae, Locris [Greece]) King  of Sparta (c. 490^180 bc). He is noted for his heroic stand against the  Persians at the Battle of Thermopylae in 480. Seeing the hopelessness of  the situation, he sent most of his troops in retreat and with his 300-man  royal guard withstood the Persian army for two days, battling valiantly  to the last man. He became the object of a hero cult at Sparta, and he  stands as the epitome of bravery against overwhelming odds. The legend  that Spartans never surrender derived from this episode.</p><p>Leonov Me-'a-noA, Aleksey (Arkhipovich) (b. May 30, 1934, near  Kemerovo, Russia, U.S.S.R.) Soviet cosmonaut. He joined the Soviet air  force in 1953 and was selected for cosmonaut training in 1959. In 1965  he became the first person to perform a spacewalk. After exiting the  spacecraft (Voskhod 2) and while tethered to the ship, Leonov made obser�  vations, took motion pictures, and practiced maneuvering in free fall  before reentering the ship. A decade later he commanded the Soyuz craft  that linked in orbit with the U.S. Apollo craft in July 1975.</p><p>Leontief Vle-'an-te-.eA, Wassily (b. Aug. 5, 1906, St. Petersburg,  Russia�d.

At Harvard University  (1931-75) he articulated his input-output analysis. He also described what  is known as the Leontief Paradox: that capital, not labour, is the scarce  factor of production in the U.S. He was awarded the 1973 Nobel Prize.  From 1975 until his death he taught at New York University.</p><p>leopard or panther Big cat {Panthera pardus) of the bush and for�  est, found throughout sub-Saharan Africa, in North Africa, and in Asia.

The dark spots arranged in rosettes over much of  the body lack a central spot, unlike those of the jaguar. The leopard is  solitary and mainly nocturnal. An agile climber, it frequently stores the  remains of its kills in tree branches. It generally preys on antelope and  deer. It also hunts dogs and, in Africa, baboons. It sometimes takes live�  stock and may attack humans. The leopard is considered an endangered  species by the U.S. but not by the IUCN (International Union for Con�  servation of Nature).

Named for its black-spotted gray coat, it attains  a maximum length and weight (greater in the female) of about 12 ft (3.5  m) and 840 lbs (380 kg). It has a reputation for ferocity but is not known  to make unprovoked attacks on humans.</p><p>Leopardi \,la-o-'par-de\, Giacomo (b. June 29, 1798, Recanati, Papal  States�d. June 14, 1837, Naples) Italian poet, scholar, and philosopher.  Congenitally deformed, he suffered throughout his life from chronic ail�  ments and frustrated hopes. His usually pessimistic poetry is admired for  its brilliance, intensity, and effortless musicality. His verse collections  include Canzoni (1824), Versi (1826), and I canti (1831). His finest poems  are probably the lyrics called �Idillii� in early editions of his poetry.  Operette morali (1827; �Minor Moral Works�) is an influential philo�  sophical exposition, mainly in dialogue form, of his doctrine of despair.  He is considered among the great Italian writers of the 19th century.</p><p>Leopold I orig. Leopold-Georges-Chretien-Frederic (b. Dec.  16, 1790, Coburg, Saxe-Coburg-Saalfeld�d. Dec. 10, 1865, Laeken,  Belg.) First king of the Belgians (1831-65). The son of Francis, duke of  Saxe-Coburg-Saalfeld, he married Charlotte, daughter of the future  English king George IV in 1816. After her death in 1817 Leopold contin�  ued to live in England until elected king of the newly formed Belgium.  He helped strengthen the country�s new parliamentary system and scru�  pulously maintained Belgian neutrality. Highly influential in European  diplomacy, he used marriages to strengthen his ties. In 1832 he married  the daughter of Louis- Philippe. In 1840 he helped arrange the marriage of  his niece, Victoria, to his nephew. Prince Albert of Saxe-Coburg-Gotha.  In 1857 he arranged the marriage of his daughter to Maximilian, archduke  of Austria.</p><p>Leopold I (b. June 9, 1640 Vienna, Austria�d. May 5, 1705, Vienna)  Holy Roman emperor (1658-1705). Son of Ferdinand III, Leopold was a  devout Catholic destined for the church, but, when his elder brother died  unexpectedly (1654), he became heir apparent to the Austrian Habsburg  lands. He was crowned successively king of Hungary (1655) and of Bohe�  mia (1656), and with his father�s death Leopold became emperor in 1658.  During his lengthy reign Austria emerged from a series of struggles to  become a great European power. In 1683 the Turks besieged Vienna and  were repulsed; war continued until the Turks were defeated and ceded  control of Hungary in the Treaty of Carlowitz (1699). Leopold also entered  into the War of the Grand Alliance, but the unfavourable peace treaty  ceded Strasbourg to France. He was drawn into the War of the Spanish  Succession, and he died before its end. His third marriage, to Eleonore of  Palatinate-Neuburg, was a happy union that produced 10 children, includ�  ing the future emperors Joseph I and Charles VI.</p><p>Leopold II orig. Leopold-Louis-Philippe-Marie-Victor (b. April  9, 1835, Brussels, Belg.�d. Dec. 17, 1909, Laeken) King of the Belgians  (1865-1909). Succeeding his father, Leopold I, he led the first European  efforts to develop the Congo River basin. In 1876 he founded an associa�  tion to explore the Congo area, with Henry Morton Stanley as his main  agent. Leopold formed the Congo Free State in 1885 and ruled as its sov�  ereign. Under Leopold, the Congo became the scene of barbarous cruelty  by the colonial masters; when news of the conditions there broke c. 1905,  it provoked an international scandal. Under British and U.S. pressure, the  region was removed from Leopold�s personal rule and annexed to Bel�  gium in 1908 as the Belgian Congo. Leopold was succeeded by his  nephew, Albert I.</p><p>Leopold II (b. May 5, 1747, Vienna�d. March 1, 1792, Vienna) Holy  Roman emperor (1790-92). Son of Maria Theresa and Emperor Francis I,  he became duke of Tuscany in 1765. A practitioner of what has been</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Leopold III &#x25BA; Lermontov I 1099</p><p>termed enlightened despotism, he built an efficient state government and  encouraged representative institutions. In 1790 he succeeded his brother  Joseph II as emperor and retained many of Joseph�s reforms. In 1792 he  allied with Prussia against revolutionary France, precipitating the French  Revolutionary Wars.</p><p>Leopold III orig. Leopold-Philippe-Charles-Albert-Meinrad-  Hubertus-Marie-Miguel (b. Nov. 3, 1901, Brussels, Belg.�d. Sept.  25, 1983, Brussels) King of the Belgians (1934-51). He succeeded his  father, Albert I, and favoured an independent foreign policy but not strict  neutrality. In World War II he assumed command of the Belgian army, but  he surrendered his encircled forces 18 days after the German invasion in  May 1940. The Belgian government repudiated his decision to surrender  and remain with his forces rather than join the government-in-exile in  London. Under house arrest through the war, he later went to Switzerland  (1945-50) to await resolution of the controversy. Though 58% of voters  voted for his return to the throne, he abdicated in 1951 in favour of his  son Baudouin.</p><p>Leopold, (Rand) Aldo (b. Jan. 11, 1887, Burlington, Iowa, U.S.�d.  April 24, 1948, near Madison, Wis.) U.S. environmentalist. After attend�  ing Yale University, he worked for the U.S. Forest Service (1909-28),  mainly in the Southwest. In 1924 the country�s first national wilderness  area (Gila Wilderness Area in New Mexico) was created at Leopold�s  urging. From 1933 to 1948 he taught at the University of Wisconsin. A  fervent campaigner for the preservation of wildlife and wilderness areas,  he was a director of the Audubon Society from 1935 and became a founder  of the Wilderness Society in the same year. His Game Management (1933)  was followed in 1949 by the posthumous A Sand County Almanac, which  eloquently called for the preservation of ecosystems. Read by millions, it  strongly influenced the budding environmental movement.</p><p>Leopold of Hohenzollern-Sigmaringen X.ho-ont-'sol-om-'zek-  ma-,riq-3n. Prince (b.

He was  a member of the Swabian line of the Hohenzollern dynasty and the brother  of Carol I of Romania. Chancellor Otto von Bismarck and Spain�s de facto  leader, Juan Prim (1814-70), persuaded the reluctant Leopold to accept  the Spanish throne, left vacant in 1868. Under French diplomatic pres�  sure, Leopold�s candidacy was withdrawn, but Prussia refused to bow to  French demands that it never be renewed.

After four hours of fighting off the coast of Lepanto,  Greece, the allies, under Juan de Austria, were victorious, capturing 117  galleys and thousands of men. The battle was of little practical value, since  Venice would surrender Cyprus to the Turks in 1573, but it had a great  impact on European morale and was the subject of paintings by Titian,  Tintoretto, and Veronese.</p><p>lepidopteran \,le-p9-'dap-t3-r3n\ Any of the more than 100,000 species  constituting the order Lepidoptera (Greek: �scaly wing�): butterflies, moths,  and skippers. The name refers to the dusting of minute scales that covers the  wings and bodies of these insects. A slender proboscis is used for sucking.  Nearly all lepidopterans are plant eaters, and species are found on every  continent except Antarctica. Females may lay from a few to a thousand or  more eggs at a time. All lepidopterans undergo complete metamorphosis.  Many types move from one region to another, sometimes crossing thou�  sands of miles of ocean, but the only species that truly migrates�the same  individuals making a two-way flight�is the monarch butterfly.</p><p>Lepidus Vle-po-dosN, Marcus Aemilius (d. 13/12 bc) Roman consul  (46, 42 bc) and triumvir (43-36). After the death of Julius Caesar, Lep�  idus controlled parts of Gaul, Spain, and Africa and wielded great influ�  ence. He and Mark Antony opposed the republican conspirators and in  43 formed the Second Triumvirate with Octavian (later Augustus). He  acquired a second Spanish province but lost Spain and Gaul to Antony  and Octavian, keeping only Africa. After helping defeat Sextus Pompeius  (36), he challenged Octavian, but his soldiers defected and he was forced  to retire.</p><p>Lepontine Ui-'pan-.tlnV Alps Segment of the central Alps along the  Italian-Swiss border.

Solitary by nature,  leprechauns lived in remote places  and worked as shoemakers. Each  was believed to possess a hidden  crock of gold. If captured and threat�  ened, a leprechaun might reveal the  gold�s hiding place, provided his  captor never took his eyes off him.</p><p>Usually the captor was tricked into  glancing away, and the leprechaun  vanished. The word derives from the  Old Irish luchorpan (�little body�).</p><p>leprosy or Hansen disease Chronic disease of the skin, peripheral  nerves, and mucous membranes of the nose, throat, and eyes, caused by  the bacterium Mycobacterium leprae. In tuberculoid leprosy, cells of the  immune system crowd into infected areas of the skin, forming hard nod�  ules, or tubercles, that spread along nerve fibres. This type of reaction  commonly leads to claw hand, gross deformity of the foot, and paralysis  of muscles of the face, eye, and neck. In the lepromatous type, bacilli  multiply freely in deep layers of the skin and spread widely through lym�  phatic channels and along nerve fibres, causing thickening and corruga�  tion of the skin, raising soft nodules on the ears, nose, and cheeks, and  sometimes destroying the septum of the nose and the palate. Leprosy has  a long history. Until the 20th century, infected people were ostracized  from society or at best segregated and cared for in isolated leper colonies.  Today the disease is entirely curable through multidrug therapy, though  tissue damage caused before drug treatment cannot be reversed. Some  600,000 new cases arise every year, mostly in Asia, Africa, Central and  South America, and the Pacific Islands. About 60 percent of new cases  occur in India.</p><p>Leptis Magna modern Labdah Largest city of ancient Tripous, located  near modem Al-Khums, Libya. Founded by the Phoenicians in the 6th  century bc, it passed to Numidia in 202 bc but broke away in 111 bc to  become an ally of Rome. The emperor Trajan made it a Roman colony.  The waning of the Roman Empire caused its decline, and it was largely  abandoned after the Arab conquest of ad 642. It has some of the best-  preserved Roman ruins in North Africa.</p><p>lepton Vlep-tan\ Any member of a class of fermions that respond only  to electromagnetic, weak, and gravitational forces and do not take part in  strong interactions. Leptons have a half-integral spin and obey the Pauli  exclusion principle. They can either carry one unit of electric charge or be  neutral. The charged leptons are the electrons, muons, and taus. Each has  a negative charge and a distinct mass. Each charged lepton has an asso�  ciated neutral partner, or neutrino, which has no electric charge and very  little if any mass.</p><p>Lerma River River, west-central Mexico. It rises southeast of Toluca  and flows northwest and then south for 350 mi (560 km) to empty into  Lake Chapala.

With its major tributaries, it constitutes Mexico�s largest river  system.</p><p>Lermontov VPer-mon-toA, Mikhail (Yuryevich) (b. Oct. 15, 1814,  Moscow, Russia�d. July 27, 1841, Pyatigorsk) Russian poet and novel�  ist. His first volume of verse, Spring, was published in 1830, the year he  entered Moscow University. He left the university two years later to enter  cadet school. A guards officer after graduating in 1834, he was twice  exiled to regiments in the Caucasus because of his passionately libertar�  ian verse. He became popular for having suffered for his poetry, which  combined civic and philosophical themes with deeply personal motifs. His  mature poems include �Mtsyri� (1840) and �Demon� (1841). His novel  A Hero of Our Time (1840), a reflection on contemporary society and the  fortunes of his generation, is written in superb prose, and the portrait of  its alienated hero profoundly influenced later Russian writers. Like Ale�  ksandr Pushkin, to whom he is often compared, he died in a duel. He is  remembered as his country�s leading Romantic poet.</p><p>Leprechaun, from the Irish Fairy Book,  by Alfred Perceval Crave, 1909.</p><p>COURTESY OF THE FOLKLORE SOCIETY LIBRARY, UNIVERSITY  COLLEGE, LONDON; PHOTOGRAPH, R.B.

June  14, 1986, New York City) U.S. librettist and lyricist. Born to a prosper�  ous retailing family, he studied at Juilliard and Harvard. He wrote more  than 500 radio scripts between 1940 and 1942, the year he met the com�  poser Frederick Loewe. The two began collaborating, and their first Broad�  way success came with Brigadoon (1947; film, 1954). It was followed by  Paint Your Wagon (1951; film, 1969). My Fair Lady (1956) was an  unprecedented triumph, setting a record for the longest original run of  any musical; the film version (1964) won seven Academy Awards. Their  film musical Gigi (1958) received nine Academy Awards. Camelot fol�  lowed in 1960 (film, 1967). Lerner also collaborated with Kurt Weill ( Love  Life , 1948) and Burton Lane (On a Clear Day You Can See Forever , 1965;  film, 1970), among others. His film scripts include An American in Paris  (1951, Academy Award).</p><p>Lerwick Town (pop., 1991: 7,336), administrative centre of the Shet�  land Islands, northern Scotland. It is on the eastern coast of the island of  Mainland. Britain�s northernmost town, it originated as a fishing village  and is notable for its herring catch. The North Sea oil boom of the 1970s  increased port traffic, and Lerwick became an oil supply and service base.

Nov. 17, 1747, Boulogne) French novelist and playwright. He  studied law in Paris but later abandoned his clerkship to devote himself  to literature. His classic The Adventures of Gil Bias of Sant Wane (1715�  35), one of the earliest realistic novels, was influential in making the  picaresque novel a European literary fashion. A prolific satirical dramatist,  he adapted Spanish models for his early plays, including the highly suc�  cessful comedy Crispin, Rival of His Master (1707). He also composed  more than 100 comedies-vaudevilles in the tradition of Moliere.</p><p>Lesage \l9-'sazh\, Jean (b. June 10, 1912, Montreal, Que., Can.�d.  Dec. 12, 1980, near Quebec, Que.) Canadian politician. He served as  Canadian minister of resources and development from 1953 to 1957. In  1958 he became leader of Quebec�s Liberal Party. When the Liberals won  the 1960 provincial elections, he became Quebec�s premier. He called for  social and cultural reform, appointing the first minister of education and  modernizing the school system and the civil service. He developed close  cultural ties between Quebec and France. After the Liberals were defeated  in 1966, he served as opposition leader until 1970.</p><p>lesbianism also called sapphism or female homosexuality,</p><p>the quality or state of intense emotional and usually erotic attraction of a  woman to another woman. First used in the late 16th century, the word  �lesbian� referred to the Greek island of Lesbos. The connotation of female  homosexuality was added in the late 19th century, when an association  was made with the poetry of Lesbian poet Sappho (c. 610-c. 580 bc). At  the turn of the 21st century, issues of concern to lesbians in Europe and  North America included legal recognition for same-sex unions, child-  rearing rights, women�s health-care, taxes, inheritance, and the sharing of  medical benefits with a partner.</p><p>Lesbos \'lez-,bas\ or Mytilene \,mit- 3 l- , e-ne\ or Mitilini</p><p>\,me-te-'le-ne\ Third largest island (pop., 1991: 87,151) in the Aegean Sea.  It occupies an area of 630 sq mi (1,630 sq km), and with two other islands  it forms a Greek department. Its main town is Mytilene. Lesbos was the  birthplace of the poet Sappho and is the source of the term lesbian. Inhab�  ited since c. 3000 bc, it was settled in c. 1050 bc by the Aetolians. After  being under Persian rule (527-479 bc), it joined the Delian League. In the  Peloponnesian War, it fell to Sparta (405 bc), but then it was recovered  for Athens (389 bc). It later flourished under Byzantium. It was ruled by  the Ottoman Empire (1462-1911) before being annexed by Greece.

In addition to performing, he became the most  celebrated piano teacher of his time, first at the conservatory in St. Peters�  burg (1852-78) and thereafter in Vienna. His students included many of  the most renowned pianists of their era, including Ignacy Paderewski and  Artur Schnabel.</p><p>leshy \'l y e-sh9y\ In Slavic mythology, a forest spirit. The leshy is an antic  spirit who enjoys playing tricks on people, though when angered he can  be treacherous. He is seldom seen, but his voice can be heard in the for�  est laughing, whistling, or singing. He often takes the shape of a man, but  his eyebrows, eyelashes, and right ear are missing, his head is pointed,  and he lacks a hat and belt. In his native forest, the leshy is as tall as the  trees, but the moment he steps beyond it, he shrinks to the size of grass.  The leshy is familiar to most Slavs living in heavily forested areas.</p><p>Leslie, Frank orig. Henry Carter (b. March 29, 1821, Ipswich, Suf�  folk, Eng.�d. Jan. 10, 1880, New York, N.Y., U.S.) British-U.S. illustra�  tor and journalist. The Illustrated London News published his early  sketches. He moved to the U.S. in 1848. There he founded numerous  newspapers and journals, including the New York Journal (1854), Frank  Leslie�s Illustrated Newspaper (1855)�having changed his name in  1857�and Frank Leslie�s Boys� and Girls� Weekly (1866). His illustra�  tions from Civil War battlefields earned him his greatest profits. His sec�  ond wife, Miriam Florence Leslie (1836-1914), legally changed her name  to Frank Leslie after his death and continued his business after his death,  twice rescuing it from debt. When she died a wealthy woman, she left  most of her estate to the feminist Carrie Chapman Catt in the service of  the suffragist cause.</p><p>Lesniewski \lesh-'nyef-ske\, Stanistaw or Stanisiaw Lesh-  niewski (b.

As a professor at the Uni�  versity of Warsaw (1919-39), he became a cofounder and leading repre�  sentative of the Warsaw school of logic. His distinctive contribution was  the construction of three interrelated formal systems, to which he gave the  Greek-derived names of protothetic, ontology, and mereology.</p><p>Lesotho \b-'su-,tu, b-'so-.toV officially Kingdom of Lesotho for�  merly Basutoland Country, southern Africa, an enclave lying within  the Republic of South Africa.

About two-thirds of the total area is mountainous; the highest point  is Mount Ntlenyana (11,424 ft [3,482 m]). The Maloti Mountains in the  central northwest are the source of two of South Africa�s largest rivers,  the Tugela and the Orange. Mineral resources are scant. Agriculture  employs nearly two-fifths of the workforce; the chief farm products are  com, sorghum, and wheat. Livestock provides exports (cattle, wool,</p><p>SOUTH AFRICA</p><p>LESOTHO</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Lesse River &#x25BA; leucite I 1101</p><p>mohair). Industries focus mainly on light manufacturing (textiles and  apparel, furniture, jewelry). Lesotho is a constitutional monarchy with two  legislative houses; its chief of state is the king, and the head of govern�  ment is the prime minister. Bantu-speaking farmers began to settle the  area in the 16th century, and a number of chiefdoms arose. The most  powerful of them organized the Basotho in 1824 and obtained British  protection in 1843 as tension between the Basotho and the South African  Boers increased. It became a British territory in 1868 and was annexed  to the Cape Colony in 1871. The colony�s effort to disarm the Basotho  resulted in revolt in 1880, and four years later it separated from the colony  and became a British High Commission Territory. It became independent  in 1966. A new constitution, effective in 1993, ended seven years of mili�  tary rule. At the beginning of the 21st century, Lesotho suffered from  internal political problems and a deteriorating economy.</p><p>Lesse River Vies, 'Ie-S9\ River, southeastern Belgium. It rises in the  Ardennes and meanders northwest for 52 mi (84 km), emptying into the  Meuse River.

A career diplomat, he held  posts in Egypt and elsewhere until  1849. In 1854 he was authorized by  the viceroy of Egypt to build a canal  across the isthmus of the Suez. He  organized a company in 1858, with  half its capital from French people,  and construction began at Port Said  in 1859. The Suez Canal was offi�  cially inaugurated in 1869. In 1879  Lesseps organized another company  to build a Panama canal, but he gave  up the project because of political  and economic difficulties. He was  prosecuted but cleared of charges of  misappropriating funds, though  French government members were  accused of bribe taking.</p><p>Lesser Armenia See Little Armenia</p><p>Lesser Slave Lake Lake, central Alberta, Canada. Located northwest  of Edmonton and south of Great Slave Lake, it occupies an area of 451 sq  mi (1,168 sq km) and drains into the Athabasca River via the Lesser Slave  River.

Oct. 22, 1919,  Kermanshah, Iran) British novelist and short-story writer. She lived on a  farm in Southern Rhodesia (now Zimbabwe) 1924^49 before settling in  England and beginning her writing career. Her works, which have often  reflected her leftist political activism, are largely concerned with people  caught in social and political upheavals. Children of Violence (1952-69),  a semiautobiographical five-novel series featuring Martha Quest, reflects  her African experience and is generally considered her most substantial  work. The Golden Notebook (1962), her most widely read novel, is a  feminist classic. Her masterful short stories are published in several col�  lections. Other works include a science-fiction novel sequence, two nov�  els published under an assumed name (Jane Somers), and  autobiographical works, including Under My Skin (1994).</p><p>Lessing, Gotthold Ephraim (b. Jan. 22, 1729, Kamenz, Upper Lus-  atia, Saxony�d. Feb. 15, 1781, Braunschweig, Brunswick) German play�  wright and critic. After writing several light comedies, he became a theatre  critic in Berlin in 1748. His play Miss Sara Sampson (1755) was the first  German domestic tragedy. After studying philosophy and aesthetics in  Breslau, he wrote the influential treatise Laocoon: An Essay on the Lim�  its of Painting and Poetry (1766). Minna von Barnhelm (1767), his fin�  est play, marks the beginning of classical German comedy. He was adviser  to the first Hamburg national theatre and published his reviews as essays  on the principles of drama in Hamburg Dramaturgy (1767-69). His  Wolfenbiittel Fragments (1774-78) attacked orthodox Christianity, arous�</p><p>ing great controversy. He also wrote the tragedy Emilia Galotti (1772)  and the famous dramatic poem Nathan the Wise (1779).</p><p>Lethe \'le-the\ Ancient Greek personification of oblivion. She was the  daughter of Eris (Strife). Her name was also applied to a river or plain in  the realm of the dead. In the Orphic mysteries it was believed that the  newly dead who drank from the River Lethe would lose all memory of  their past existence. The initiated were taught to drink instead from Mne�  mosyne, the river of Memory.</p><p>Leto Vle-to\ In classical mythology, the mother of Apollo and Artemis.  She was made pregnant by Zeus, and she wandered in search of a place  to give birth until she found the barren island of Delos. The island was a  floating rock borne about by the waves, but it was fixed to the bottom of  the sea for the birth of Apollo and Artemis. In some versions, Leto�s wan�  derings are ascribed to the jealousy of Zeus�s wife, Hera.</p><p>Letterman, David (b. April 12, 1947, Indianapolis, Ind., U.S.) U.S.  television talk-show host. He began his career as a stand-up comedian and  was a guest host of Johnny Carson�s Tonight Show from 1979. He hosted  NBC�s post-midnight Late Night with David Letterman (1982-93), win�  ning six Emmy Awards and great popularity with his ironic, abrasive, flip�  pant style of interviewing, which critics viewed as a parody of talk shows.  Since 1993 he hosted The Late Show with David Letterman on CBS.</p><p>letterpress printing or relief printing or typographic print�  ing In commercial printing, process by which many copies are produced  by repeated direct impression of an inked, raised surface against sheets  or a continuous roll of paper. Letterpress is the oldest traditional printing  technique, the only important one from the time of Johannes Gutenberg  ( c. 1450) until lithography (late 18th century) and especially offset print�  ing (early 20th century). The ink-bearing surface for a page of text was  originally assembled letter by letter and line by line. The Monotype and  Linotype were the first keyboard-activated typesetting machines. Letterpress  can produce high-quality work at high speed, but requires much time to  prepare and adjust the press. For the sake of speed, newspapers are now  printed by the offset process.</p><p>Lettish language See Latvian language</p><p>lettre de cachet \ , letr 3 -d3-ka- , sha\ (French: �letter with a seal�) Let�  ter bearing an official seal, signed by the king and countersigned by a  secretary of state, used primarily to authorize someone�s imprisonment  without trial. An important instrument of administration under the ancien  regime in France, lettres de cachet were greatly abused in the 17th�18th  century. Their use was abolished in 1790.</p><p>lettuce Cultivated annual salad plant ( Lactuca sativa ) that produces clus�  ters of crisp, water-filled leaves. The  best-known varieties are head, or  cabbage, lettuce (variety capitata)',  leaf, or curled, lettuce (variety  crispa)�, cos, or romaine, lettuce  (variety longifolia)', and asparagus  lettuce (variety asparagina). Head  lettuce is further divided into butter  heads and crisp heads (e.g., iceberg  lettuce). In the U.S, large-scale farms  grow mainly crisp-head varieties,  shipping them nationwide. Small-  scale, local farmers raise leaf and  butter-head varieties. Lettuce is an  early annual crop that grows best in  cool weather and with ample water.</p><p>Though usually consumed in salads, it may also be cooked.</p><p>leucine Vlu-,sen\ One of the essential amino acids, present in most com�  mon proteins and particularly abundant in hemoglobin.

A  dolphin carried Melicertes� body to  the Isthmus of Corinth, and the Isth�  mian Games were instituted in his  honour.</p><p>leukemia Cancer of blood-  forming tissues with high levels of  leukocytes. Radiation exposure and  hereditary susceptibility are factors  in some cases. In acute leukemias,  anemia, fever, bleeding, and lymph-  node swelling develop rapidly. Acute  lymphocytic leukemia, found mostly  in children, was once over 90% fatal in six months. Drug therapy can now  cure more than half these children. Acute myelogenous (granulocytic) leu�  kemia, found mostly in adults, has frequent remissions and recurrences,  and few patients survive long. Chronic myelogenous leukemia most often  begins in the 40s; weight loss, low fever, weakness, and other symptoms  may not develop immediately. Chemotherapy helps the symptoms but may  not prolong life. Chronic lymphocytic leukemia, mostly in the elderly, may  be inactive for years. Survival rates are better than in myelogenous leuke�  mia; most deaths are caused by infection or hemorrhage.</p><p>leukocyte \ l lu-ko- l sIt\ or white blood cell or white corpuscle</p><p>Any of several types of blood cells that help defend the body from infec�  tion. The different mature forms�granulocytes, including neutrophils  (heterophils), basophils, and eosinophils; monocytes, including macroph�  ages; and lymphocytes �have different functions, including ingesting bac�  teria, protozoans, or infected or dead body cells; producing antibodies; and  regulating the action of other leukocytes. They act mostly in the tissues  and are in the bloodstream only for transport. Blood normally contains  5,000-10,000 leukocytes per cu mm.</p><p>leukoderma See vitiligo</p><p>Levant \b-'vant\ Historical name for the countries along the shores of  the eastern Mediterranean Sea. It was applied to the coastlands of Anato�  lia and Syria, sometimes extending from Greece to Egypt. The term was  often associated with Venetian trading ventures. It was also used as a syn�  onym for the Middle or Near East. In the 16th�17th centuries the term  High Levant referred to the Far East (East Asia). The name Levant States  was given to the French mandate of Syria and Lebanon after World War  I (1914-18).</p><p>level Device for establishing a horizontal plane. It consists of a small,  sealed glass tube containing liquid and an air bubble; the tube is fixed  horizontally in a block or frame with a smooth lower surface. When the  bubble is in the middle of the glass tube, the device is on a level surface;  adjustment to the horizontal is indicated by movement of the bubble. The  glass tube is slightly bowed, and the level�s sensitivity is proportional to  the radius of curvature.</p><p>Leveler Member of a republican faction in England during the English  Civil Wars and Commonwealth. The name was coined by the movement�s  enemies to suggest that its supporters wished to �level men�s estates.�  The movement began in 1645-46 and demanded that sovereignty rest with  the House of Commons (to the exclusion of king and lords), believing  that manhood suffrage would make Parliament truly representative. The  Levelers dominated the New Model Army, but the Putney debates in the  army council discussing the Levelers� new social contract (1647) ended  in deadlock. The generals restored army discipline by force, ending the  Levelers� political power.</p><p>Leven Vle-vonX, Loch Lake, east-central Scotland. Roughly 3 mi (5 km)  in diameter, it is one of the shallowest of the Scottish lochs, having an</p><p>average depth of 15 ft (4.5 m). It contains a subspecies of brown trout  known as Loch Leven trout. Castle Island, one of the lake�s seven islands,  has the ruins of a 14th-century castle where Mary, Queen of Scots, was  imprisoned (1567-68).</p><p>lever Simple machine used to amplify physical force. All early people  used the lever in some form, for moving heavy stones or as digging sticks  for land cultivation. Balance beams for weighing were probably used in  Egypt c. 5000 bc; they consist of a bar pivoted at its center with weights  on one end balancing the object on the other. As early as 1500 bc people  were raising water and lifting soldiers over battlements using the swape  or shadoof, a long lever pivoted near one end with a platform or container  hanging from the short arm and counterweights attached to the long arm.</p><p>Lever Bros. \1e-var\ British soap and detergent manufacturer. Lever  Bros, was founded in 1885 by William Hesketh Lever, later Viscount  Leverhulme (1851-1925), and his brother, James Darcy Lever, to make  and sell soap. The first company to market wrapped bars of soap made  from vegetable oil instead of tallow, Lever Bros, expanded internation�  ally with the help of energetic advertising slogans. It built a model indus�  trial village at Port Sunlight in 1888 and offered employee benefits such  as profit sharing and free insurance. William was elected to Parliament in  1906 and became a viscount in 1922. In 1929, Lever Bros, joined an  association of European companies to form Unilever.</p><p>Levertov, Denise (b.

She  married an American writer after the war and moved to the U.S., where  she was associated with the Black Mountain group, which included the  poets Charles Olson and Robert Duncan. Influenced by the deliberate  simplicity of William Carlos Williams�s poetry, she wrote deceptively  matter-of-fact verse on both personal and political themes. Among her  poetry collections are Here and Now (1957), The Sorrow Dance (1967),  and The Freeing of the Dust (1975).</p><p>Levesque \la-'vek\, Rene (b. Aug. 24, 1922, New Carlisle, Que.,  Can.�d.

He joined  the Canadian Broadcasting Corporation in 1946, became a war corre�  spondent in Korea in 1952, and was a television commentator from 1956  to 1959. Elected to the Quebec legislature in 1960, he joined the admin�  istration of Jean Lesage. In 1967 he cofounded a separatist group that com�  bined with others to form the Parti Quebecois. In 1976 his party won  control of the Quebec assembly, and he became premier. He proposed an  independent Quebec in economic union with the rest of Canada, an  arrangement he called �sovereignty-association.� In 1980 his plan was  rejected by the Quebec electorate. He resigned in 1985 because of fail�  ing health.</p><p>Levi \'le-,vl\ In ancient Israel, the third son of the patriarch Jacob. Levi  became head of the clans of religious functionaries known as Levites.  Unlike the 12 tribes of Israel, the Levites were given no allotment of land  when Canaan was conquered.

Two years after obtaining a degree in  chemistry, Levi, who was Jewish, was captured by the Nazis and sent to  Auschwitz as a slave labourer. His autobiographical works �If This Is a  Man, or Survival in Auschwitz (1947), The Reawakening (1963), and The  Drowned and the Saved (1986)�are restrained and moving accounts of  and reflections on survival in the Nazi camps. His best-known work, The  Periodic Table (1975), is a collection of 21 meditations, each named for  a chemical element. The lingering effects of his wartime trauma may have  led to his suicide.</p><p>Levi \la-'ve\, Sylvain (b. March 26, 1863, Paris, France�d. Oct. 30,  1935, France) French scholar of Eastern religion, literature, and history. He  taught at the Sorbonne (1889-94) and later for many years at the College de  France (1894-1935). In 1929, with Takakusu Junjiro, he published a clas�  sic dictionary of Buddhism. His other writings include the standard treatise  The Indian Theater (1890), Nepal (1905-08), and India and the World  (1926); he also carried out pioneering studies of the Tocharian languages.</p><p>Levi-Strauss \'la-ve-'straus\, Claude (b.

At  the New School for Social Research  in New York City (1941^15) he came  under the influence of the linguist  Roman Jakobson; he came to view  culture as a system of communica�  tion, analogous to a language, and  constructed models based on struc�  tural linguistics, information theory,  and cybernetics to interpret them. He  attempted to identify universal struc�  tures of the mind as reflected in myths,  cultural symbols, and social organiza�  tion. From 1950 to 1974 he was  director of studies at the Ecole Pra�  tique des Hautes Etudes, and in 1959  he joined the faculty of the College  de France. Among his major works are The Elementary Structures of Kin�  ship (1949), Tristes tropiques (1955), Structural Anthropology (1961, vol.  2, 1973), and the four-volume Mythologiques (1964�71).</p><p>Levi Strauss &amp; Co. Leading U.S. manufacturer of casual and active  clothing, noted especially for its blue denim jeans. The company traces  its origin to Levi Strauss (1829-1902), a Bavarian immigrant who sold  dry goods to miners during the California gold rush. Hearing of the min�  ers� need for durable pants, he hired a tailor to make garments out of tent  canvas, later substituting denim. In 1873 he and an associate received a  patent for the copper riveting they used to strengthen their pants. The  company�s most spectacular growth occurred after 1946, with the deci�  sion to concentrate wholly on manufacturing clothing under its own label.

The company went public in 1971 and was  returned to private control (by Strauss�s descendants) in 1985.</p><p>Levinas, Emmanuel (b. Dec. 30, 1905 [Jan. 12, 1906, Old Style],  Kaunas, Lith.�d. Dec. 25, 1995, Paris, France) French philosopher. He  studied at the Universities of Strasbourg and Freiburg and received a doc�  torate in philosophy from the Institut de France in 1928. His philosophi�  cal work in the 1930s helped to introduce the phenomenology of Edmund  Husserl and Martin Heidegger to France. Levinas�s best-known work,  Totality and Infinity (1961), is a highly original phenomenological inves�  tigation of ethics and the self that takes as its starting point the face-to-  face encounter between the �I� and the �Other.� Extensively developed  in Otherwise Than Being; or, Beyond Essence (1974) and other writings,  this analysis challenged Western philosophical tradition by treating eth�  ics rather than ontology as �first philosophy.� Levinas was also the author  of religious studies, including Difficult Freedom: Essays on Judaism  (1963) and Nine Talmudic Readings (1990).</p><p>Levine \b-'vln\, James (Lawrence) (b. June 23, 1943, Cincinnati,  Ohio, U.S.) U.S. conductor. He debuted as a pianist at age 10 with the  Cincinnati Symphony Orchestra. At Juilliard he studied piano with Ros-  ina Lhevinne (1880-1976) and conducting with Jean Morel (1903-75).  He was assistant conductor of the Cleveland Orchestra from 1964 to 1970.  A guest appearance conducting Tosca (1971) led to his appointment as  principal conductor (1973) and later music director (1975) and artistic  director (1986) of the Metropolitan Opera. He built the flagging Met  orchestra into a virtuoso ensemble and became recognized as one of the  world�s greatest conductors. He served as director of Chicago�s Ravinia  Festival from 1973 to 1993.</p><p>Levinson, Barry (b. April 6, 1942, Baltimore, Md., U.S.) U.S. film  director. He worked as a comedy writer for Carol Burnett and Mel Brooks  in the 1970s, then made his directorial debut with Diner (1982), the first  of several movies set in his native city. He followed it with The Natural  (1984), Young Sherlock Holmes (1985), Tin Men (1987), and Good Morn�  ing, Vietnam (1987). Noted for his directorial versatility, ranging from  drama and crime stories to political satire, he also created the highly  popular Rain Man (1988, Academy Award), Avalon (1990), Bugsy (1991),  Sleepers (1996), Wag the Dog (1997), and The Perfect Storm (2000).</p><p>levirate and sororate \ , le-vo-r3t... , s6r-3-r3t\ Customs or laws regu�  lating marriage following the death of a spouse, or in some cases during</p><p>the lifetime of the spouse. The levirate decrees a dead man�s brother to  be the widow�s preferred marriage partner. In ancient Hebrew society, this  practice served to perpetuate the line of a man who died childless. Often,  the brother who marries his sister-in-law is a proxy for the deceased and  no new marriage is contracted, since all progeny are acknowledged as the  seed of the dead man. The sororate decrees the marriage of a man to his  deceased wife�s sister or, under so-called sororal polygyny, to the wife�s  younger sisters as they come of age. The latter was practiced by some  American Indian tribes in the 19th century and continues among the Aus�  tralian Aborigines.</p><p>Leviticus Rabbah \li-'vi-ti-k3s-ra-'ba\ (c. ad 450) Compilation of 37  compositions on topics suggested by the Old Testament Book of Leviti�  cus. Their message is that the laws of history focus on the holy life of  Israel (the Jewish people). If the Jews obey the laws of society aimed at  Israel�s sanctification, then the foreordained history will unfold as Israel  hopes. Israel, for its part, can affect its own destiny. Thus salvation at the  end of history depends on sanctification in the here and now.</p><p>Levitt, Helen (b. Aug. 31, 1913, New York, N.Y., U.S.) U.S. photog-  rapher. She began her career in photography at age 18. Her first show,  �Photographs of Children,� was held at the Museum of Modern Art in  New York in 1943. It featured the subject matter�children, especially the  underprivileged�and humanity that characterize much of her work. In  the mid 1940s Levitt collaborated with the novelist James Agee, filmmaker  Sidney Meyers, and painter Janice Loeb on The Quiet One, a prizewin�  ning documentary about a young African American boy. For most of the  1960s she concentrated on film editing and directing. Levitt resumed her  pursuit of photography in the 1970s.</p><p>Levittown Extensive suburban housing development in Hempstead,  Long Island, N.Y. Developed 1946-51 by the firm of Levitt and Sons,  Inc., it was an early example of a completely preplanned and mass-  produced housing complex. It contained thousands of low-cost homes  (with accompanying shopping centers, playgrounds, swimming pools,  community halls, and schools). Levitt repeated the formula in Bucks  County, Pa. (1951-55). The name Levittown became equated with simi�  lar developments built across the country in the postwar building boom.  Though once widely deplored, his towns differ from other, usually  monotonous, middle-class speculative developments in their meandering  roads and lush plantings.</p><p>levodopa or L-dopa Organic compound (L-3,4-dihydroxyphenylala-  nine) from which the body makes dopamine, a neurotransmitter deficient  in persons with parkinsonism.

After training and  teaching in Berlin, he immigrated to the U.S., where he taught at the Uni�  versity of Iowa (1935�45) and later became director of a group dynam�  ics research centre at the Massachusetts Institute of Technology (1945-  47). He is best known for his field theory of behaviour, which holds that  human behaviour is a function of an individual�s psychological environ�  ment. To fully understand and predict human behaviour, according to  Lewin, one must view the totality of events in a person�s psychological  field, or �lifespace.� His works include A Dynamic Theory of Personality  (1935) and Field Theory in Social Science (1951).</p><p>Lewis, C(larence) l(rving) (b.

Irish-born British scholar and writer.  Lewis taught first at Oxford (1925-54) and later at Cambridge (1954-63).  An early volume, the critical Allegory of Love (1936) on medieval and  Renaissance literature, is often considered his finest scholarly work. He  became known in England and the U.S. for several series of BBC radio  broadcasts during the war years on the subject of Christianity. Many of  his books embrace Christian apologetics; the best known is The Screwtape  Letters (1942), a satirical epistolary novel in which an experienced devil  instructs his young charge in the art of temptation. Also well known are  The Chronicles of Narnia (1950-56), a series of seven children�s stories  (including The Lion, the Witch, and the Wardrobe , 1950) that have become  classics of fantasy; and a science-fiction trilogy, known mostly for its first  volume, Out of the Silent Planet (1938).</p><p>Lewis, (Frederick) Carl(ton) (b. July 1, 1961, Birmingham, Ala.,  U.S.) U.S. track-and-field athlete. He qualified for the 1980 Olympics but  did not participate, because of the U.S. boycott of the Moscow games. At  the 1984 Olympics he won the 100-m and 200-m races, the long jump,  and the 4 x 100-m relay. At the 1988 Olympics he won the long jump  (becoming the first athlete ever to win that event consecutively) and the  100-m race and received a silver medal in the 200-m. In 1992 he again  won the long jump and anchored the winning U.S. 4 x 100-m relay team,  and in 1996 he astounded observers by winning a fourth consecutive  long-jump title.</p><p>Lewis, David (Kellogg) (b. Sept. 28, 1941, Oberlin, Ohio, U.S.�d.  Oct. 14, 2001, Princeton, N.J.) U.S. philosopher. He taught at the Uni�  versity of California at Los Angeles from 1966 to 1970 and thereafter at  Princeton University. A wide-ranging thinker, Lewis made important�in  some cases groundbreaking�contributions to a number of fields. He was  best known for his extreme realism regarding possible worlds; his defense  of the IDENTITY THEORY in the PHILOSOPHY OF MIND (see also MIND-BODY PROBLEM);  and his doctrine of �Humean supervenience� (named for the Enlighten�  ment philosopher David Hume), according to which all truths about any  possible world are determined by the distribution of properties attribut�  able to specific points in space and time in that world (see supervenience).  At the time of his death, he was widely considered the leading figure in  ANALYTIC PHILOSOPHY.</p><p>Lewis, Edward B. (b. May 20, 1918, Wilkes-Barre, Pa., U.S.�d. July  21, 2004, Pasadena, Calif.) U.S. geneticist. He received a Ph.D. (1942)  in genetics from the California Institute of Technology, where he taught  from 1946 to 1988. By crossbreeding thousands of fruit flies, he discov�  ered that genes are arranged on the chromosome in the order correspond�  ing to body segments, an orderliness now known as the colinearity  principle. Lewis�s work helped explain mechanisms of general biologi�  cal development, including the causes of deformities present at birth in  humans. With Christiane Niisslein-Volhard and Eric F. Wieschaus, he was  awarded a 1995 Nobel Prize.</p><p>Lewis, Jerry orig. Joseph Levitch (b. March 16, 1926, Newark,  N.J., U.S.) U.S. actor, director, and producer. In 1946 he developed a  nightclub comedy routine with Dean Martin (1917-95), who played the  suave crooner to Lewis�s zany clown, and they appeared together in 16  movies, including My Friend Irma (1949) and Pardners (1956), before  ending their partnership in 1956. Lewis then directed, produced, and acted  in movies such as The Bellboy (1960) and The Nutty Professor (1963).  These films, along with his collaborations with director Frank Tashlin, led  many critics (especially in Europe) to regard Lewis as the comic heir to  Charlie Chaplin and Buster Keaton. Since 1966 Lewis has hosted the U.S.  annual Muscular Dystrophy Telethon.</p><p>Lewis, Jerry Lee (b. Sept. 29, 1935, Ferriday, La., U.S.) U.S. rock-  and-roll musician. He began playing piano in his childhood, influenced  by blues and gospel musicians. He attended Bible school in Texas but  was expelled. Returning to Louisiana, he played in several bands, per�  fecting his signature �pumping� piano technique (the left hand maintain�  ing a driving boogie pattern while the right played flashy ornamentation).  His first hits came in 1957 with �Whole Lotta Shakin� Goin� On� and  �Great Balls of Fire.� In 1958 it was discovered that he had married a  13-year-old relative, and his record sales dropped. Though he had a few  more hits, he concentrated on his famously energetic and uninhibited live  performances. His career continued to be plagued by controversy.</p><p>Lewis, John L(lewellyn) (b. Feb. 12, 1880, near Lucas, Iowa,  U.S.�d. June 11, 1969, Washington,</p><p>D.C.) U.S. labour leader. The son of  Welsh immigrants, he became a coal  miner at age 15. He rose through the  ranks of the United Mine Workers of  America (UMWA) and from 1911  was also an organizer of the Ameri�  can Federation of Labor (AFL), with  which the miners� union was affili�  ated. As president of the UMWA  (1920-60), Lewis joined several  other AFL union leaders in forming  the Committee for Industrial Organi�  zation (1935) to organize workers in  mass-production industries. On  breaking with the AFL (see AFL-  CIO), Lewis and other dissident  union heads founded the Congress of  Industrial Organizations. As its  president (1936-40), Lewis presided  over the often-violent struggle to  introduce unionism into previously unorganized industries such as steel  and automobiles.

His professional career began in 1989 in  England. He won the World Boxing Council (WBC) heavyweight title in  1992, lost it in 1994, and recaptured it in 1997. In 1999 he faced Ameri�  can Evander Holyfield, who held the heavyweight titles of the World Box�  ing Association (WBA) and the International Boxing Federation (IBF). In  a controversial decision, the fight was called a draw. In the rematch that  same year Lewis emerged as the undisputed champion, thereby unifying  the heavyweight title. (The IBF and WBA portions of the title were later  taken from Lewis because of disputes concerning mandatory fights, but  he retained the WBC title and was still considered the undisputed cham�  pion by many in boxing.) In his 2002 bout with American Mike Tyson,  Lewis knocked Tyson out in the eighth round.</p><p>Lewis, Matthew Gregory (b. July 9, 1775, London, Eng.�d. May  4, 1818, at sea) English novelist and dramatist. The sensational success  of his gothic novel The Monk (1796) earned him the nickname �Monk�  Lewis. Its horror, violence, and eroticism brought it a wide readership,  though it was universally condemned. Lewis also wrote a popular music  drama in the same vein, The Castle Spectre (1798). After inheriting a large  fortune in Jamaica in 1812, he sailed twice to the island to inquire about  the treatment of slaves on his estates there, and he died at sea. Journal of  a West India Proprietor (1834) attests to his humane and liberal attitudes.</p><p>Lewis, Meriwether (b. Aug. 18, 1774, near Charlottesville, Va.�d.  Oct. 11, 1809, near Nashville, Tenn., U.S.) U.S. explorer. After serving  in the militia during the Whiskey Rebellion (1794) in western Pennsyl�  vania, he transferred into the regular army. In 1801 he became private  secretary to Pres. Thomas Jefferson, who selected him to lead the first  overland expedition to the Pacific Northwest, including the area of the  Louisiana Purchase. At Lewis�s request, William Clark was appointed to  share the command. The success of the Lewis and Clark Expedition (1804-  06) was greatly due to Lewis�s  preparation and skill. At its conclu�  sion, he and Clark each received  1,600 acres of land as a reward.</p><p>Lewis was named governor of Loui�  siana Territory in 1808.

He won the 1930 Nobel Prize for Literature, the first  given to an American. His later novels include Cass Timberlaine (1945).  Lewis�s reputation declined in later years, and he lived abroad much of  the time. He was married to Dorothy Thompson from 1928 to 1942.</p><p>Lewis, (Percy) Wyndham (b. Nov. 18, 1882, on a yacht near  Amherst, Nova Scotia, Can.�d. March 7, 1957, London, Eng.) English  artist and writer. The founder and principal exponent of Vorticism, Lewis  began a short-lived Vorticist review titled Blast in 1914. His first novel,  Tarr, appeared in 1918. The Childermass (1928) was followed by the huge  satirical novel The Apes of God (1930) and The Revenge for Love (1937).  In the 1930s he produced some of his most noted paintings, including The  Surrender of Barcelona (1936). He also wrote essays, short stories, and  two admired memoirs. Notorious in the 1930s for championing fascism,  he later recanted those beliefs.</p><p>Lewis and Clark Expedition (1804-06) First overland expedition  to the U.S. Pacific coast and back, led by Meriwether Lewis and William  Clark. Initiated by Pres. Thomas Jefferson, the expedition set out to find  an overland route to the Pacific, documenting its exploration through the  new Louisiana Purchase. About 40 men, skilled in various trades, left St.  Louis in 1804. They traveled up the Missouri River into present-day North  Dakota, where they built Fort Mandan (later Bismarck) and wintered  among the Mandan Sioux. They left the next spring, hiring Toussaint  Charbonneau and his Indian wife, Sacagawea, who served as guide and  interpreter. They traveled through Montana and by horse over the Con�  tinental Divide to the headwaters of the Clearwater River. They built  canoes to carry them to the Snake River and then to the mouth of the  Columbia River, where they built Fort Clatsop (later Astoria, Ore.) and  spent the winter. On the journey back the group divided, then reunited to  canoe down the Missouri to St. Louis, arriving to great acclaim in Sep�  tember 1806. All but one member of the expedition survived. The jour�  nals kept by Lewis and others documented Indian tribes, wildlife, and  geography and did much to dispel the myth of an easy water route to the  Pacific.</p><p>Lexington City (pop., 2000: 260,512), north-central Kentucky, U.S.  Named in 1775 for Lexington, Mass., after the Battles of Lexington and  Concord, it was chartered in 1782 and was the site of the first session of  the Kentucky legislature (1792). Incorporated as a city in 1831, it merged  with Fayette county in 1974 to create an urban county government. It is  the seat of Transylvania University (founded 1780) and the University of  Kentucky, and it is also the headquarters of the American Thoroughbred  Breeders Association.</p><p>Lexington and Concord, Battles of (April 19, 1775) Initial skir�  mishes between British soldiers and American colonists that marked the  beginning of the American Revolution. En route from Boston to seize the  colonists� military stores at Concord, Mass., the British force of 700 was  met at Lexington by 77 local minutemen (see minuteman) alerted by Paul  Revere and others. Which side fired the first shot is unclear, and resistance  soon ended. The British moved on to nearby Concord, where they were  met by more than 300 American patriots and were forced to withdraw. On  their march back to Boston, they were continually harried by colonists  firing from behind bams, trees, and roadside walls. Deaths totaled 273  British and 95 Americans.</p><p>Leyden See Leiden</p><p>Leyden, Lucas van See Lucas van Leyden</p><p>Leyster Vla-storV Judith (b. July 28, 1609, Haarlem, Neth.�d.

Many of her known  works, primarily portraits, genre paintings, and still lifes, were formerly  attributed to her male contemporaries. Though the influence of Frans Hals  is clear, she was also interested in the Baroque style of the Utrecht school.  She embraced a greater range of subjects than other Dutch painters of the  era and was one of the first to depict domestic scenes.</p><p>Leyte \'la-te\ Island (pop., 2000: 1,952,496) of the Visayan group, east�  ern Philippines.

After the U.S.  amphibious landing on the Philippine island of Leyte (Oct. 20), the Japa�  nese reacted with a plan to decoy the U.S. fleet north while moving three  attack forces into Leyte Gulf. The U.S. discovery of one of the forces as  it moved into position set off three days of continuous surface and air  clashes. In the largest naval battle of the war, U.S. forces crippled the  Japanese fleet and forced it to withdraw, allowing the U.S. to complete  its invasion of the Philippines.</p><p>Lezama Lima \la-'za-ma-Te-ma\, Jose (b.

After  studying law in Havana, Lezama was associated with several literary  reviews and later with a literary group that published the work of young  poets who revolutionized Cuban letters. Among his works are the poetry  volumes Muerte de Narciso (1937) and La fijeza (1949) and the essay  collections Analecta del reloj (1953) and La expresion americana (1957).  The novel Paradiso (1966), considered his masterpiece, reaffirms his faith  in his art and his own aestheticism in the face of the 1959 revolution, of  which he largely disapproved.</p><p>Lhasa Vla-soV Capital (pop., 2003 est.: 129,490), Tibet Autonomous  Region, China. Located at an elevation of 11,975 ft (3,650 m) in the  Tibetan Himalayas near the Lhasa River, it has served as the religious cen�  tre of Tibet since at least the 9th century ad. Lhasa became Tibet�s capi�  tal in 1642 and remained so after the Chinese communists asserted control  of the region in 1951; it was designated capital of the Tibet Autonomous  Region in 1965. The 7th-century temple of Gtsug-lag-khang is consid�  ered the holiest in Tibet. Other landmarks include the temple of Klu-  khang; the Potala Palace, the Dalai Lama�s former winter residence; and  monasteries.

It states that  when the limit of f(x)/g(x) is indeterminate, under certain conditions it  can be obtained by evaluating the limit of the quotient of the derivatives  of /and g (i .e., f'(x)/g'(x)). If this result is indeterminate, the procedure  can be repeated. It is named for the French mathematician Guillaume de  L�Hopital (1661-1704), who purchased the formula from his teacher the  Swiss mathematician Johann Bernoulli (1667-1748).</p><p>Lhotse \'lot-'sa\ Peak in the Himalayas. Located on the Nepal-Tibet  boundary and reaching 27,890 ft (8,501 m), it is one of the world�s highest  mountains. It is sometimes considered part of Mount Everest�s massif  because it is joined to that peak by a 25,000-ft (7,600-m) ridge. The Swiss  climbers Fritz Luchsinger and Ernest Reiss made the first ascent of the  mountain in 1956.

He participated in the compilation of the official his�  tories of the Jin (265^120) and Sui (581-618) dynasties, writing the chap�  ters containing historical outlines of Chinese astronomy, astrology,  metrology, and a mathematical theory of music. In 648 he became the  director of the Imperial Astronomical Bureau, and he coedited a collec�  tion of mathematical treatises used as manuals in the Mathematical Col�  lege of the State University. Later he prepared the Linde calendar, which  was promulgated in 665 and used until 728.</p><p>Li Vle-'da-'jatA Dazhao or Li Ta-chao (b. Oct. 6, 1888, Hebei prov�  ince, China�d. April 28, 1927, Beijing) Cofounder with Chen Duxiu of  the Chinese Communist Party (CCP). Chief librarian and professor of his�  tory at Beijing University, Li became inspired by the success of the Rus�  sian Revolution and began to study and lecture on Marxism. In 1921 the  study groups Li had created formally became the CCP. Li helped the new  party carry out the policy of the Communist International (see Comintern)  and cooperated with the Nationalist Party of Sun Yat-sen. His career was  cut short when he was seized and hanged by the warlord Zhang Zuolin,  but his ideas of a revolution of the impoverished peasantry were brought  to fruition by Mao Zedong.</p><p>Li Vle-'hurj-'jaqN Hongzhang or Li Hung-chang (b. Feb. 15, 1823,  Hefei, Anhui province, China�d. Nov. 7, 1901, Beijing) Chinese states�  man who represented China in the series of humiliating negotiations at  the end of the Sino-French War (1883�85), Sino-Japanese War (1894-95),  and Boxer Rebellion (1900). Much earlier in his career, Li had helped with  the suppression of the Taiping Rebellion (1850-64) and had put down the  Nian Rebellion (c. 1852-68). At that time, he came in contact with West�  erners (notably England�s Charles George Gordon) and Western weapons  and became convinced that China needed Western-style firepower if it  wanted to protect its sovereignty. In 1870, when Li was appointed  governor-general of the capital province, Zhili, he was able to build arse�  nals, found a military academy, establish two modern naval bases, pur�  chase warships, and undertake other �self-strengthening� measures.  Through modernization he hoped to preserve traditional China, but within  traditional China Li�s innovations could not develop fully, and he was  fatally hampered by the system he was trying to protect.</p><p>Li Keran or Li K'o-jan orig. Li Yongshun alias Sanqi (b. March  26, 1907, Xuzhou, Jiangsu province, China�d. Dec. 5, 1989, Beijing)  Chinese painter and art educator. While studying at the Shanghai Art Col�  lege he was influenced by Kang Youwei, who advocated merging Eastern  and Western art to create a new century in Chinese painting. At the Hang�  zhou National Art College (1929-32) Li studied with the French teacher  Andre Claoudit and developed an abstract and structural painting style  that showed the influence of German Expressionism. In 1932 he became a  member of the leftist Yiba Art Society. In the 1940s he began to paint  cowboys and water buffalo, revitalizing this traditional subject matter with  an innovative technique of splashed ink. He joined the faculty of the  Beijing National Art College in 1946. While he emulated ancient Chinese  calligraphy, his training in oil painting also taught him to apply Western  elements, such as chiaroscuro, to his work. In his later years, Li attracted  many students and followers, who formed the �Li School� of the 1980s.</p><p>Li Po See Li Bai</p><p>Li Rui (b. Jan. 15, 1769, Yuanhe, China�d. Aug. 12, 1817, Yuanhe) Chi�  nese mathematician and astronomer who made notable contributions to  the revival of traditional Chinese mathematics and astronomy and to the</p><p>development of the theory of equations. Having failed the Chinese civil  service examinations several times, he could obtain no official position  and had to make a poor living as an assistant to various mandarins. From  about 1800 he began to study the works of the 13th-century mathemati�  cians Li Ye and Qin Jiushao. He found that traditional Chinese methods of  solving higher-degree equations had several advantages over algebraic  methods that had been recently imported from the West. His Kaifang shuo  (1820; �On the Method of Extraction�) contains his work on the theory  of equations: a rule of signs, a discussion of multiple roots and negative  roots, and the rule that nonreal roots of an algebraic equation must exist  in pairs.</p><p>Li Shanlan also known as Li Renshu or Li Qiuren (b. Jan. 2, 1811,  Haining, Zhejiang province, China�d. Dec. 9, 1882, China) Chinese  mathematician. He mastered both traditional Chinese and available West�  ern mathematical treatises at a precocious age. In Shanghai in 1852, he  met Alexander Wylie of the London Missionary Society and agreed to  collaborate on the translation of Western works. Along with his near con�  temporary Hua Hengfang, Li left a permanent impression on Chinese  mathematical nomenclature and exposition. From 1869 Li was professor  of mathematics at the Tongwen Guan college, the first Chinese person to  hold such a Western-style position in mathematics.</p><p>Li Shaojun Vle-'shau-'juuA (fl. 2nd century bc, China) Chinese alche�  mist. He was the first person to assert that the Daoist�s ultimate goal was  to achieve the status of xian, immortal sage, and he was responsible for  much of the mystical content of popular Daoist thought. Claiming to be  several centuries old, he gained the confidence of the great Han emperor  Wudi and persuaded him that he could become immortal by praying to  Zao Jun, a mythical Chinese figure who produced gold dinnerware that  conferred immortality, and by eating from a vessel that had been trans�  muted into gold. Because of Li�s influence, prayers to Zao Jun became  established in Daoist ritual, and Zao Jun came to be considered the first  great Daoist divinity.</p><p>Li Si \'le-'su\ or Li Ssu (b. 280 bc?, Chu state, central China�d. 208 bc,  Xianyang, Shaanxi province) Minister of the Qin dynasty in China who  utilized the ideas of Hanfeizi to make the Qin the first centralized Chinese  empire. His ordering of the �Qin bibliocaust��the burning of all books�  earned him the opprobrium of future generations of Confucian scholars.</p><p>Li Sixun or Li Ssu-hsun (b. 651�d. 716) Chinese painter. Li, who  was related to the Tang imperial family, led an active political life and  was given the honorary rank of general. His son, Li Zhaodao, was also a  famous painter, and thus the father is sometimes called Big General Li  and the son Little General Li. While no genuine works survive, both Li  Sixun and Li Zhaodao are known to have painted in a highly decorative  and meticulous fashion, employing the precise line technique derived  from earlier artists such as Gu Kaizhi and Zhan Ziqian. Li is considered  the chief exponent of a decoratively coloured landscape style of the Tang  dynasty and the founder of the so-called Northern school of professional  painters.</p><p>Li Ta-chao See Li Dazhao</p><p>Li Tang or Li T'ang (b. c. 1050�d. c. 1130) Chinese painter. He earned  the highest rank in the academy of painting of Emperor Huizong, and after  the North fell to the Mongols he went to the South and entered the acad�  emy of Emperor Song Gaozong. His landscapes serve as a vital link  between the earlier, and essentially Northern, variety of monumental land�  scape, and the more lyrical Southern style of the Ma-Xia school (based  on the work of Ma Yuan and Xia Gui). Li perfected the brushstroke tex�  ture known as the �ax stroke,� which gives a tactile sense to painted rocks  and suggests the precise and comprehensive reality that Southern Song  artists sought to give their landscapes.</p><p>Li Ye literary name iingzhai (b. 1192, Luangcheng, Hebei province,  China�d. 1279, Yuanshi) Chinese mathematician and scholar-official  who contributed to the solution of polynomial equations in one variable.  When the Mongols invaded his home district in 1233, Li wandered home�  less in Shanxi, Shandong, and Henan provinces. During this period he  composed his main work, Ceyuan haijing (1248; �Sea Mirror of Circle  Measurements�), which contains 170 problems based on one geometric  diagram of a circular city wall circumscribed by a right-angled triangle.  Although the problems are highly contrived, they enabled Li to list some  692 algebraic formulas for triangular areas and segment lengths. In 1264  Li was appointed to the Hanlin Academy by Kublai Khan.

Nov. 1, 1630, Beijing) Chi�  nese mathematician, astronomer, and geographer whose translations of  European scientific books greatly contributed to the spread of Western  science in China. In 1601 he met the Italian Jesuit Matteo Ricci, who bap�  tized him in 1610. By engraving and printing numerous copies of Ricci�s  world map, Li altered many Chinese views of world geography. Li and  Ricci translated Christopher Clavius�s arithmetic primer Epitome arith-  meticae practicae (1585; �Selected Arithmetic Methods�) as Tongwen  suanzhi (1614). This book systematically introduced European-style  mathematical notation, while Li included complementary elements from  traditional Chinese mathematics. He also brought together and published  a series of books composed by the Jesuits with Chinese help, Tianxue  chuhan (1629; �First Collection of Writings on Heavenly Learning�), that  included 20 Western scientific and religious titles.</p><p>Li Zicheng Vle-'dzii-'choqX or Li Tzu-ch'eng (b. Oct. 3, 1605?, Mizhi,  Shaanxi province, China�d. 1645, Hubei province) Rebel leader who  brought about the fall of China�s Ming dynasty (1368-1644). A former  postal worker, he joined the rebel cause in 1631 following a great famine  in the northern part of the country. In 1644 he proclaimed himself the first  emperor of a new dynasty and marched on Beijing, which he took easily.  His victory was short-lived; Wu Sangui, a general loyal to the Ming, called  on the Manchu tribes to drive him out, and he fled north, where he was  probably killed by local villagers.

The policy  covers losses resulting from acts or omissions that are legally deemed to  be negligent and that result in damage to the person, property, or legiti�  mate interests of others. It was principally the introduction of the auto�  mobile that spurred the rapid growth of this form of insurance, which now  extends to a great many activities in addition to driving, including mal�  practice insurance for doctors and other professionals, marine liability for  boat owners and operators, and product liability for manufacturers of  consumer goods. See also casualty insurance, consumer protection.</p><p>liana \le-�a-n3\ or liane \le-�an\ Any of various long-stemmed, woody  vines, especially of tropical rain forests, that are rooted in the soil and  climb or twine around other plants as they grow upward. Lianas often  form a tangled network, up to 330 ft (100 m) high, around and among the  trees that support them.</p><p>Liao dynasty Vlyau\ (907-1125) Dynasty formed by the nomadic Khi-  tan tribes in much of present-day Manchuria, Mongolia, and the north�  eastern corner of China proper. The Chinese portion of the empire was  governed on the Tang pattern, while the northern part was set up on a  tribal basis. After the establishment of the Song dynasty (960-1279), the  Liao carried out a border war for control of northern China. Eventually  the Song agreed to pay the Liao an annual tribute. The Juchen, former  subjects of the Liao, destroyed the dynasty in 1125 but adopted most of  its governmental system. The name �Cathay� for China derives from  Khitay, another name for the Khitan.</p><p>Liao Vlyau\ River River, Liaoning province and Inner Mongolia autono�  mous region, China. The East Liao rises in the mountains of Jilin prov�  ince and the West Liao in southeastern Inner Mongolia. They merge and  flow southwest as the Liao to empty into the Gulf of Liaodong, after a  course of 836 mi (1,345 km). The river�s drainage basin occupies 83,000  sq mi (215,000 sq km). It is navigable by small boats for about 400 mi  (645 km) from its mouth.</p><p>Liaodong Vlyau-'duq\ Peninsula or Liao-tung Peninsula Pen�  insula, extending from the southern coastline of Liaoning province, north�  eastern China. It partly separates the Bo Hai (Gulf of Chihli) on the west  from Korea Bay on the east. It forms part of a mountain belt that con�  tinues in the Changbai Mountains; on the peninsula the range is known  as the Qian Mountains. Near the southern tip of the peninsula lies the port  of Dalian.</p><p>Liaoning \'lyau-'niq\ formerly (1903-28) Fengtian or Feng-t'ien  Yfoq-�tyenV Province (pop., 2002 est.: 42,030,000), northeastern China. It  lies on the Yellow Sea and is bordered by North Korea, Jilin and Hebei  provinces, and Inner Mongolia. With an area of 58,300 sq mi (151,000 sq</p><p>km), it is the southernmost of the three provinces that form the region of  Manchuria. Its capital is Shenyang. It has four main topographical regions:  the central plains, the Liaodong Peninsula, the western highlands, and the  eastern mountain zone. In 1932�45 it was part of the Japanese puppet  state of Manchukuo. Shenyang was taken by the Chinese communists in  1948. Liaoning is China�s most industrialized province, producing steel,  cement, crude oil, and electrical power.</p><p>liar paradox Paradox derived from the statement attributed to the  Cretan prophet Epimenides (6th century bc) that all Cretans are liars. If  Epimenides� statement is taken to imply that all statements made by Cret�  ans are false, then since Epimenides was a Cretan, his statement is false  (i.e., not all Cretans are liars). The paradox�s simplest form arises from  considering the sentence �This sentence is false.� If it is true, then it is  false, and if it is false, then it is true. Consideration of such semantic para-  Doxes led logicians to distinguish between object language and metalan�  guage and to conclude that no language can consistently contain a  complete semantic theory for its own sentences.</p><p>Liard River Vle-ord\ River, northwestern Canada. Rising in the Yukon  Territory, it flows southeast through British Columbia. It then turns north�  east and empties into the Mackenzie River in the Northwest Territories, after  a course of 693 mi (1,115 km). Its upper course has rapids and canyons;  its lower course is navigable for small boats. It is named for the liards  (poplar trees) along its course.</p><p>Libby, Willard (Frank) (b.

In Classical antiq�  uity, the term designated the education proper to a freeman (Latin liber,  �free�) as opposed to a slave. In the medieval Western university, the  seven liberal arts were grammar, rhetoric, and logic (the trivium ) and  geometry, arithmetic, music, and astronomy (the quadrivium). In modem  colleges and universities, the liberal arts include the study of literature,  languages, philosophy, history, mathematics, and science.</p><p>Liberal-Democratic Party (LDP) Japan�s largest political party,  which held power almost continuously from its formation in 1955 until  1993. It was created through the amalgamation and transformation of vari�  ous factions of the prewar Rikken SeiyOkai and Minseito parties. The conser�  vative LDP appeared threatened in the 1970s but survived; the end of the  1980s boom years (the �bubble economy�), financial crises, and political  scandals finally caused the party to lose its majority in the Diet in 1993. It  came back to power in a coalition government in 1994, and since then LDP  prime ministers have included Obuchi Keizo and Koizumi Jun'ichiro.</p><p>Liberal Parly British political party that emerged in the mid-19th cen�  tury as the successor to the Whigs. It was the major party in opposition  to the Conservative Party until 1918, after which it was supplanted by the  Labour Party. It was initially supported by the middle class that was enfran�  chised by the Reform Bill of 1832. Earl Russell�s administration in 1846  is sometimes regarded as the first Liberal government, but the first  unequivocally Liberal government was formed in 1868 by William E.</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1108 I Liberal Party of Canada &#x25BA; libertarianism</p><p>L_</p><p>N</p><p>Gladstone.

It championed individualism, pri�  vate enterprise, human rights, and promotion of social justice; wary of  imperial expansion, it was pacific and internationalist. During World War  I it split into two camps, centred on H.H. Asquith and David Lloyd George.  It continued as a minor party until 1988, when it merged with the Social  Democratic Party to form the Liberal Democratic Party.</p><p>Liberal Party of Canada One of the two major Canadian political  parties. It originated in two reformist opposition groups, Rouges and Clear  Grits, that emerged in the mid-19th century in what are now the provinces  of Quebec and Ontario, respectively. The first Liberal government was  headed by Alexander Mackenzie (1873-78). The party regained power  under Wilfred Laurier (1896-1911) and was the ruling party for much of  the 20th century under such prime ministers as W.L. Mackenzie King, Louis  Saint Laurent, Lester Pearson, Pierre Trudeau, and Jean Chretien. Like the  Conservative Party (later the Progressive Conservative Party), the Liberal  Party comprises diverse regional, ethnic, religious, and class interests.</p><p>liberalism Political and economic doctrine that emphasizes the rights  and freedoms of the individual and the need to limit the powers of gov�  ernment. Liberalism originated as a defensive reaction to the horrors of  the European wars of religion of the 16th century (see Thirty Years' War).  Its basic ideas were given formal expression in works by Thomas Hobbes  and John Locke, both of whom argued that the power of the sovereign is  ultimately justified by the consent of the governed, given in a hypotheti�  cal social contract rather than by divine right (see divine kingship). In the  economic realm, liberals in the 19th century urged the end of state inter�  ference in the economic life of society. Following Adam Smith, they argued  that economic systems based on free markets are more efficient and gen�  erate more prosperity than those that are partly state-controlled. In  response to the great inequalities of wealth and other social problems cre�  ated by the Industrial Revolution in Europe and North America, liberals in  the late 19th and early 20th centuries advocated limited state intervention  in the market and the creation of state-funded social services, such as free  public education and health insurance. In the U.S. the New Deal program  undertaken by Pres. Franklin D. Roosevelt typified modern liberalism in its  vast expansion of the scope of governmental activities and its increased  regulation of business. After World War II a further expansion of social  welfare programs occurred in Britain, Scandinavia, and the U.S. Eco�  nomic stagnation beginning in the late 1970s led to a revival of classical  liberal positions favouring free markets, especially among political con�  servatives in Britain and the U.S. Contemporary liberalism remains com�  mitted to social reform, including reducing inequality and expanding  individual rights. See also conservatism; individualism.</p><p>liberalism, theological School of religious thought characterized by  concern with inner motivation as opposed to external controls. It was set  in motion in the 17th century by Rene Descartes, who expressed faith in  human reason, and it was influenced by such philosophers as Benedict de  Spinoza, G. W. Leibniz, and John Locke. Its second stage, which coincided  with the Romantic movement of the late 18th and 19th century, was  marked by an appreciation of individual creativity, expressed in the writ�  ings of philosophers such as Jean-Jacques Rousseau and Immanuel Kant as  well as of the theologian Friedrich Schleiermacher. The third stage, from the  mid-19th century through the 1920s, emphasized the idea of progress.  Stimulated by the Industrial Revolution and by Charles Darwin�s Origin of  Species (1859), thinkers such as T. H. Huxley and Herbert Spencer in  England and William James and John Dewey in the U.S. focused on the  psychological study of religious experience, the sociological study of reli�  gious institutions, and philosophical inquiry into religious values.</p><p>liberation theology Roman Catholic movement that originated in the  late 20th century in Latin America and seeks to express religious faith by  helping the poor and working for political and social change. It began in  1968, when bishops attending the Latin American Bishops� Conference  in Medellin, Colom., affirmed the rights of the poor and asserted that  industrialized nations were enriching themselves at the expense of the  Third World. The movement�s central text, A Theology of Liberation  (1971), was written by the Peruvian priest Gustavo Gutierrez (b. 1928).  Liberation theologians have sometimes been criticized as purveyors of  Marxism, and the Vatican has sought to curb their influence by appointing  more conservative prelates.</p><p>Liberation Tigers of Tamil Eelam or Tamil Tigers Guerrilla  organization seeking to establish an independent Tamil state in northern</p><p>and eastern Sri Lanka. Formed in 1972, it is considered one of the world�s  most sophisticated and tightly organized insurgent groups. By 1985 it con�  trolled the port of Jaffna and most of the Jaffna Peninsula in northern Sri  Lanka. After losing control of Jaffna in 1987, it carried out several attacks,  including the assassinations of the Sri Lankan president and the former  Indian prime minister and a suicide bombing that killed 100 people in the  capital of Colombo. Negotiations between the Tigers and the government  broke down in the mid-1990s, and fighting subsequently intensified until  February 2002 when a permanent cease-fire agreement was signed.</p><p>Liberia officially Republic of Liberia Republic, western Africa.  Area: 37,743 sq mi (97,754 sq km). Population (2005 est.): 2,900,000.  Capital: Monrovia. Liberia�s ethnic groups include the Americo-</p><p>Liberians, descendants of the black freed-  men who emigrated from the U.S. in the  19th century; and 16 indigenous peoples of  the Mande, Kwa, and Mel linguistic  groups. Languages: English (official),  indigenous languages. Religions: traditional beliefs, Christianity, Islam.  Currency: Liberian dollar. Liberia has coastal lowlands extending 350 mi  (560 km) along the Atlantic; farther inland are hills and low mountains.  Roughly one-fifth of Liberia consists of tropical rainforest. Agriculture is  the main component of the economy, but only a portion of the arable land  is cultivated. The country also has rich iron-ore reserves, which are a  major source of exports. The principal cash crops are rubber, coffee, and  cacao; the staple crops are rice and cassava. Constitutionally, Liberia is a  republic with two legislative houses, and its head of state and government  is the president; however, since 2003 it has been under a transitional gov�  ernment with a chairman. Africa�s oldest republic, Liberia was established  on land acquired for freed U.S. slaves by the American Colonization  Society, which founded a colony at Cape Mesurado in 1821. In 1822  Jehudi Ashmun, a Methodist minister, became the director of the settle�  ment and Liberia�s real founder. In 1824 the territory was named Liberia,  and its main settlement was named Monrovia. Joseph Jenkins Roberts  proclaimed Liberian independence in 1847 and expanded its boundaries.  Border disputes with the French and British lasted until 1892, when its  boundaries were officially established. In 1980 a coup led by Gen. Sam�  uel K. Doe marked the end of the Americo-Liberians� long political domi�  nance over the indigenous Africans. A rebellion in 1989 escalated into a  destructive civil war in the 1990s. A peace agreement was reached in  1996, but fighting broke out again in 1999 and lasted until 2003, when a  transitional government was installed, backed by UN peacekeepers.</p><p>libertarianism Political philosophy that stresses personal liberty.

Among the thinkers embraced by libertarians are  Henry David Thoreau and Ayn Rand.</p><p>Liberty, Sons of Organization of American colonists formed in 1765  to oppose the Stamp Act. The name was taken from a speech by Isaac  Barre in the British Parliament that referred to American colonials who  opposed unjust British measures as �sons of liberty.� The group agitated  for colonial resistance and helped prevent enforcement of the Stamp Act.  After the act�s repeal, the organization continued to oppose British mea�  sures against the colonists.</p><p>Liberty Party (1840-48) U.S. political party formed by a splinter group  of abolitionists. It was created by Arthur Tappan and Theodore Weld in  opposition to William Lloyd Garrison, who scorned political action as a  futile way to end slavery. At its first party convention in 1840, James Bir-  ney was nominated for U.S. president. By 1844 the party had influenced  undecided legislators in many local elections to adopt antislavery stands.  In 1848 it dissolved when many of its members joined the Barnburners  (see Hunkers and Barnburners) to form the Free Soil Party.</p><p>libido \b-�be-do\ Physiological and emotional energy associated with  the sex drive. The concept was originated by Sigmund Freud, who saw the  libido as linked not only with sexual desire but with all constructive  human activity.

The word  derives from the Latin liber (�book�). The origin of libraries lies in the  keeping of written records, a practice that dates at least to the 3rd mil�  lennium bc in Babylonia. The first libraries as repositories of books were  those of the Greek temples and those established in conjunction with the  Greek schools of philosophy in the 4th century bc. Today�s libraries fre�  quently contain periodicals, microfilms, tapes, videos, compact discs, and  other materials in addition to books. The growth of on-line communica�  tions networks has enabled library users to search electronically linked  databases worldwide.

Classifications  may be natural (e.g., by subject), artificial (e.g., by alphabet, form, or  numerical order), or accidental (e.g., chronological or geographic). They  also vary in degree; some have minute subdivisions while others are  broader. Widely used systems include the Dewey Decimal Classification, the  Library of Congress Classification, the Bliss Classification, and the Colon  Classification; special libraries may devise their own unique systems.</p><p>Library of Alexandria See Library of Alexandria</p><p>Library of Congress U.S. library, the largest and one of the greatest of  what may be considered national libraries.

In addition to  serving as a reference source for members of Congress and other govern�  ment officers, it is outstanding among the learned institutions of the world,  with magnificent collections of books, manuscripts, music, prints, and  maps. It contains some 18 million books, 2.5 million recordings, 12 million  photographs, 4.5 million maps, and more than 54 million manuscripts.</p><p>Library of Congress Classification or LC Classification Sys�  tem of library organization developed during the reorganization of the U.S.  Library of Congress.

It divides</p><p>the field of knowledge into 20 large classes and an additional class for gen�  eral works. Each main class has a synopsis that also serves as a guide.

Pongoue people first  settled the region after the 16th century, followed by the Fang in the 19th  century. The French built a fort on the estuary�s northern bank in 1843,  and in 1849 a settlement of freed slaves and a group of Pongoue villages  were given the name Libreville. In 1850 France abandoned its fort and  resettled on the plateau, now the commercial and administrative centre of  the city. It is well industrialized and is Gabon�s educational centre. Libre�  ville was the capital of French Equatorial Africa from 1888 to 1904.</p><p>Libya officially Socialist People's Libyan Arab Jamahiriya</p><p>\ja-m3-hi-'re-y3\ Country, North Africa. Area: 679,362 sq mi (1,759,540  sq km). Population (2005 est.): 5,853,000. Capital: Tripoli. Berbers, once</p><p>the major ethnic group, have been largely  assimilated into the predominant Arab cul�  ture; sub-Saharan Africans are among the  other ethnic groups. Languages: Arabic  (official), Berber (Amazigh). Religions:  Islam (official; predominantly Sunni); also Christianity. Currency: Libyan  dinar. All but two tiny fractions of Libya are covered by the Sahara: Tri-  politania in the northwest and Cyrenaica in the northeast. Tripolitania is  Libya�s most important agricultural region and its most populated area.  The production and export of petroleum are the basis of Libya�s economy;  other resources include natural gas, manganese, and gypsum. Livestock  raising, including sheep and goats, is important in the north. Libya is a  socialist state with one policy-making body; the head of government is  the prime minister, but Muammar al-Qaddafi has been the de facto head  of state and real power in Libya since 1970. The early history is that of  Fezzan, Cyrenaica, and Tripolitania, which the Ottoman Empire combined  under one regency in Tripoli in the 16th century.

The scene of much fighting in the war, it  became an independent state in 1951 and a member of the Arab League in  1953. The discovery of petroleum in 1959 brought wealth to Libya. A  decade later, a group of army officers led by al-Qaddafi deposed the king  and made the country an Islamic republic. Under al-Qaddafi, Libya sup�  ported the Palestinian Liberation Organization (PLO) and allegedly pro�  vided aid for international terrorist groups. Intermittent warfare with Chad  that had begun in the 1970s ended with Libya�s defeat in 1987. A U.S.  trade embargo (endorsed by the UN), imposed on Libya in the 1990s for  its purported connection to terrorism, began to be lifted in 2003.</p><p>Libyan Desert Northeastern portion of the Sahara, extending from  eastern Libya through southwestern Egypt into northwestern Sudan.

These extremely hardy, slow growers often are pio�  neer species in sparse environments such as mountaintops and the far  North. Fungal cells, anchored to the substrate with hairlike growths  (rhizines), form the base. In the body (thallus), numerous algal cells are  distributed among fewer fungal cells. Through photosynthesis the algal  cells provide simple sugars and vitamins for both partners in this symbi�  otic association. The fungal cells protect the algal cells from environmen�  tal extremes. Lichens may form a thin, crustlike, tightly bound covering  over their substrate (e.g., cracks in rocks), or they may be small and leafy,  with loose attachments to the substrate. Their colours range from brown  to bright orange or yellow. In far northern Europe and Asia, lichens pro�  vide two-thirds of caribou and reindeer food. They have been the source  of medicines and dyes.</p><p>Lichtenstein Vlik-ton-.stln, 'lik-ton-.stenV, Roy (b. Oct. 27, 1923, New  York, N.Y., U.S.�d.

Especially  popular are his brilliantly coloured paintings in the style of large-scale  comic strips, such as Whaam (1963). In the mid 1960s he began making  Pop versions of well-known paintings by artists such as Claude Monet,  Pablo Picasso, and Henri Matisse. In the 1970s he also made sculptures, in  which he reproduced Art Deco forms. In the 1980s he painted a five-  story-high mural in a New York City office building.</p><p>Licinius \b-'si-ne-9s\ orig. Valerius Licinianus Licinius (d. 325)  Roman emperor (308-324). Bom of Illyrian peasant stock, he advanced  in the army and in 308 was appointed augustus by his friend the emperor  Galerius. Because the empire was split up among several emperors at that  time (see tetrarch), his domain was confined to Pannonia. After the death  of Galerius in 311, he allied with Constantine I, defeated his competitor  Maximinus in Asia Minor, and partitioned the empire (313). Although  reputedly converted to Christianity, he grew alienated and launched a  campaign of mild persecution against the Christians c. 320. Constantine  soon drove him from power and had him executed.</p><p>Licking River River, eastern Kentucky, U.S. It flows about 320 mi (515  km) generally northwest to enter the Ohio River at Covington, Ky., oppo�  site Cincinnati, Ohio.

Later novels include The Barque �Future � (1872), One of  Life's Slaves (1883), and the classic The Family at Gilje (1883), which  deals with the position of women. He sought to reflect in his writings the  nature, folk life, and social spirit of his country.

Educated  in law at the University of Kristiania (Oslo), Lie was active in the Nor�  wegian Labour Party before being appointed foreign minister of Norway�s  government-in-exile during World War II. As a member of the Norwegian  delegation to the UN Conference on International Organization (1945),  he helped draft the provisions for the United Nations Security Council. As  secretary-general, he helped to secure the removal of Soviet troops from  Iran; he also dealt with the first Arab-Israeli war and the India-Pakistan  conflict over Kashmir. The Soviet Union ceased to cooperate with him after  he supported UN intervention in the Korean War, and his effectiveness  was further hampered by charges from anticommunist politicians in the  U.S. that his secretariat had employed subversives. He resigned in 1952.</p><p>lie detector or polygraph Instrument for recording physiological  phenomena (including blood pressure, pulse rate, and respiration) of a human  subject as he or she answers questions asked by an operator. These data  (recorded as graphs) are used as the basis for judging whether the sub�  ject is lying. The phenomena usually chosen for recording are those not  easily controlled voluntarily. The types of questions asked, their wording,  and the mode of presentation have a tremendous effect on the results and  their reliability. Used in police interrogation and investigation since 1924,  the lie detector is still controversial among psychologists and not always  accepted as evidence in courts.</p><p>Liebermann Vle-bor-.manN, Max (b.

He was the first to demonstrate the existence  of free radicals and did much to clarify the properties of acids. He devel�  oped simple analytical methods (see analysis) that greatly aided his work,  analyzed many tissues and body fluids, and showed that plants use car�  bon dioxide, water, and ammonia.

It is located between Switzerland and  Austria. Area: 62 sq mi (160 sq km). Population (2005 est.): 34,800.  Capital: Vaduz. The Liechtensteiners are descended from the Alemanni  tribe that came into the region after ad 500. Languages: German (official),  Alemanni dialect, Walser dialect. Religions: Christianity (predominantly  Roman Catholic; also Protestant); also Islam. Currency: Swiss franc. The  eastern two-thirds of Liechtenstein�s small territory is composed of the  foothills of the Rhatikon Massif, part of the central Alps. The western sec�  tion of the country is occupied by the Rhine River floodplain. Liechtenstein  has no natural resources of commercial value, and virtually all raw mate�  rials, including wood, have to be imported. Manufacturing includes met-</p><p>cal situation and its absolute bank secrecy.  It is a constitutional monarchy with one legislative house; its chief of state  is the prince, and the head of government is the prime minister. The Rhine  plain was occupied for centuries by two independent lordships of the Holy  Roman Empire, Vaduz and Schellenberg. The principality of Liechtenstein,  consisting of these two lordships, was founded in 1719 and remained part  of the Holy Roman Empire. It was included in the German Confederation  (1815-66). In 1866 it became independent, recognizing Vaduz and Schel�  lenberg as unique regions forming separate electoral districts. In 1921 it  adopted Swiss currency, and in 1923 it joined the Swiss customs union.  A coalition that ruled Liechtenstein for almost 60 years dissolved in 1997.  Into the early 21st century Prince Hans Adam II continued his long�  standing battle for constitutional changes that would increase his powers.</p><p>lied Vlet\ German song, particularly an art song for voice and piano of  the late 18th or the 19th century. The Romantic movement fostered seri�  ous popular poetry by poets such as Johann Wolfgang von Goethe. Com�  posers often set such poetry to folk-influenced music, but the lied could  also be highly sophisticated and even experimental. At first generally per�  formed at private social gatherings, it eventually moved into the concert-  hall repertoire. The most influential and prolific lied composer was Franz  Schubert, who wrote more than 600; Robert Schumann, Felix Mendelssohn,  Johannes Brahms, Hugo Wolf, Gustav Mahler, and Richard Strauss are most  prominent in the bed�s subsequent history.</p><p>Liege Vlyezh\ Flemish Luik Vloik\ City (pop., 2000 est.: 185,639), east�  ern Belgium.

It became a town when St. Hubert transferred his see there in 721,  and it was noted as a centre of learning in the Middle Ages. Annexed to  France in 1795, it was later assigned with the rest of Belgium to The  Netherlands in 1815. A centre of the successful revolt for Belgian inde�  pendence in 1830, it is now an industrial research centre and a major port.</p><p>liege \lej\ In European feudal society, an unconditional bond between a  man and his overlord.

Though Liezi is traditionally  named as its author, in its present form it probably dates from the 3rd or  4th century ad. Like earlier Daoist classics, it emphasizes the mysterious  dao (way). The �Yang Zhu� chapter acknowledges the futility of chal�  lenging the dao and asserts that all one can look forward to in life is sex,  music, physical beauty, and material abundance.

One of the most popular and  widely imitated of U.S. magazines, it was founded by Henry R. Luce and  quickly became a cornerstone of Time-Life Publications. From the start  it emphasized photography, with gripping, superbly chosen news photo�  graphs, photographic features, and photo-essays by the best photogra�  phers; gradually more writing was added. Its war coverage�particularly  that of World War II�was notably vivid, authentic, and moving. Life  ceased publication largely because its costs outstripped revenues.

Life insurance is most developed in wealthy  countries, where it has become a major channel of saving and investing.  There are three basic types of life-insurance contract. Term insurance is  issued for a specified number of years; protection expires at the end of  the period and there is no cash value remaining. Whole-life contracts run  for the whole of the insured�s life and also accumulate a cash value, which  is paid when the contract matures or is surrendered; the cash value is less  than the policy�s face value. Endowment contracts run for a specified time  period and pay their full face value at the end of the period.</p><p>life span Time between birth and death. It ranges from a mayfly�s day  to certain trees� thousands of years. Its limit appears to depend on hered�  ity, but such factors as (in humans) disease, natural disasters, war, diet,</p><p>and habits such as smoking reduce it. Maximum life span is theoretical;  more meaningful is average life span, which life-insurance companies and  actuaries analyze and tabulate. Long-lived progenitors tend to beget long-  lived descendants. A very-low-calorie diet appeal�s to prolong life.  Reduced infant mortality and improved sanitation and nutrition account  for much of the increase since c. 1800�from about 35 to over 70 years  in most industrialized countries.

An aircraft in flight  experiences an upward lift force, as well as the thrust of the engine, the  force of its own weight, and a drag force. The lift force arises because  the speed at which the displaced air moves over the top of the airfoil (and  over the top of the attached boundary layer) is greater than the speed at  which it moves over the bottom and because the pressure acting on the  airfoil from below is therefore greater than the pressure from above.</p><p>lift-slab construction Technique whereby concrete floor slabs are  poured on the ground, one on top of the other, and then lifted into place  on top of columns by hydraulic jacks.

Common ligands  include the neutral molecules water (H 2 0), ammonia (NH 3 ), and carbon  monoxide (CO) and the anions cyanide (CN - ), chloride (Cl - ), and hydrox�  ide (OH - ). Rarely, ligands are cations and electron-pair acceptors (elec�  trophiles). Organic ligands include EDTA (see chelate) and nitrilotriacetic  acid. Biological systems rely on ligands such as the porphyrin in hemoglo�  bin and chlorophyll, and numerous cofactors are ligands. In chelates, the  ligand attaches at more than one point, sharing more than one electron  pair, and is called bidentate or polydentate�having two or many �teeth.�  The ligands in a complex may be the same or different.</p><p>Ligeti \le-'ga-te\, Gyorgy (Sandor) (b.

By 1950  he was teaching at the Budapest Academy, but not until he met Karlheinz  Stockhausen and others in Vienna in 1956 did he find his compositional  path. After a brief interest in electronic music, he gained international  recognition for his avant-garde pieces for performers; these works dealt  principally with shifting masses of sound and tone colours. His most  famous work, Atmospheres (1961), was used in the film 2001: A Space  Odyssey (1968).

Like all electromagnetic radiation, it travels through  empty space at a speed of about 186,000 mi/sec (300,000 km/sec). In the  mid- 19th century, light was described by James Clerk Maxwell in terms  of electromagnetic waves, but 20th-century physicists showed that it  exhibits properties of particles as well; its carrier particle is the photon.

In platform framing, each floor is framed  separately, as contrasted with balloon framing, in which the studs (verti�  cal members) extend the full height of the building. Freed from the heavy  timbers of the post-and-beam system, platform framing offers ease of con�  struction. Carpenters first fabricate a floor, which consists of wood joists  and subflooring. The floor often serves as a working platform on which  the stud wall frames are fabricated in sections and then lifted into place.  On top of this is placed a second floor or the roof. The roof is formed of  rafters (sloping joists) or wood trusses. The standard interior wall sheath�  ing is gypsum board (drywall), which provides fire-resistance, stability,  and a surface ready for finishing. Framed structures traditionally were  constructed individually at each house site; today many of the framing  elements are mass-produced elsewhere and assembled on-site.</p><p>light quantum See photon</p><p>light-year Distance traveled by light moving in a vacuum in one year,  at its accepted speed of 186,282 mi/second (299,792 km/second).

The first known light�  house was the Pharos of Alexandria. The modern lighthouse dates only  from the early 18th century. Initially made of wood, these towers were  often washed away in severe storms. The first lighthouse made of inter�  locking masonry blocks was built on the treacherous Eddystone Rocks  reef, off Plymouth, England (1759). Interlocking masonry blocks  remained the principal material of lighthouse construction until they were  replaced by concrete and steel in the 20th century. Modern construction  methods have facilitated the building of offshore lighthouses. The most  common illuminant is the electric-filament lamp. Refinements in lenses  (e.g., the Fresnel lens) and reflectors made it possible to substantially  increase the light�s intensity. Radio and satellite-based navigation systems  have greatly reduced the need for large lighthouses in sighting land.</p><p>lighting Use of an artificial source of light for illumination. It is a key  element of architecture and interior design. Residential lighting uses  mainly either incandescent lamps or fluorescent lamps and often depends  heavily on movable fixtures plugged into outlets; built-in lighting is typi�  cally found in kitchens, bathrooms, and corridors and in the form of hang�  ing pendants in dining rooms and sometimes recessed fixtures in living  rooms. Lighting in nonresidential buildings is predominantly fluorescent.  High-pressure sodium-vapor lamps (see electric discharge lamp) have higher  efficiency and are used in industrial applications. Halogen lamps have resi�  dential, industrial, and photographic applications. Depending on their fix�  tures, lamps (bulbs) produce a variety of lighting conditions. Incandescent  lamps placed in translucent glass globes create diffuse effects; in recessed  ceiling-mounted fixtures with reflectors, they can light walls or floors  evenly. Fluorescent fixtures are typically recessed and rectangular, with  prismatic lenses, but other types including indirect cove lights (see coving)  and luminous ceilings, in which lamps are placed above suspended trans�  lucent panels. Mercury-vapor and high-pressure sodium-vapor lamps are  placed in simple reflectors in industrial spaces, in pole-mounted streetlight  fixtures, and in indirect up-lighting fixtures for commercial applications.</p><p>lightning Visible discharge of electricity when part of the atmosphere  acquires enough electrical charge to overcome the resistance of the air.  During a thunderstorm, lightning flashes can occur within clouds, between</p><p>clouds, between clouds and air, or from clouds to the ground. Lightning  is usually associated with cumulonimbus clouds (thunderclouds) but also  occurs in nimbostratus clouds, in snowstorms and dust storms, and some�  times in the dust and gases emitted by a volcano. A typical lightning flash  involves a potential difference between cloud and ground of several hun�  dred million volts. Temperatures in the lightning channel are on the order  of 30,000 K (50,000 �F). A cloud-to-ground flash comprises at least two  strokes: a pale leader stroke that strikes the ground and a highly luminous  return stroke. The leader stroke reaches the ground in about 20 millisec�  onds; the return stroke reaches the cloud in about 70 microseconds. The  thunder associated with lightning is caused by rapid heating of air along  the length of the lightning channel. The heated air expands at supersonic  speeds. The shock wave decays within a metre or two into a sound wave,  which, modified by the intervening air and topography, produces a series  of rumbles and claps.

After cellulose, it is the most  abundant organic material on Earth, making up one-fourth to one-third of  the dry weight of wood, where it is concentrated in the cell walls.  Removed from wood pulp in the manufacture of paper, it is used as a binder  in particleboard and similar products and as a soil conditioner, filler in  certain plastics, adhesive ingredient, and raw material for chemicals  including dimethyl sulfoxide and vanillin (synthetic vanilla flavouring).</p><p>lignite Yellow to dark brown, rarely black, coal that has been formed  from PEAT under moderate pressure; it is one of the first products of coal-  ification and is intermediate between peat and subbituminous coal. Dry lig�  nite contains about 60-70% carbon. Almost half of the world�s total coal  reserves contain lignite and subbituminous coal, but lignite has not been  exploited to any great extent because lignite is inferior to higher-rank  coals (e.g., bituminous coal) in heating value, ease of handling, and stor�  age stability. In some areas, however, the scarcity of fuel has led to exten�  sive developments.</p><p>Liguria Region (pop., 2001 prelim.: 1,560,748), northwestern Italy. Cov�  ering 2,092 sq mi (5,418 sq km) and located on the Ligurian Sea between  France and Tuscany, it has its capital at Genoa. Under Roman rule from  the 1 st century bc, the region was briefly controlled by the Lombards and  Franks during the Middle Ages. The city of Genoa emerged as a leading  power as early as the 11th century, and by 1400 the entire region ben�  efited from its maritime and commercial powers. In 1815 the Congress  of Vienna gave Liguria to the kingdom of Piedmont-Sardinia. It contrib�  uted significantly to the union of Italy in 1861. Its economy is based on  agriculture, tourism, and industries centred on its major cities, including  Genoa. La Spezia is a major naval base.</p><p>likelihood or chance In mathematics, a subjective assessment of pos�  sibility that, when assigned a numerical value on a scale between impos�  sibility (0) and absolute certainty (1), becomes a probability (see probability  theory). Thus, the numerical assignment of a probability depends on the  notion of likelihood. If, for example, an experiment (e.g., a die toss) can  result in six equally likely possible outcomes, the probability of each is V6.</p><p>Likud \li-'kud\ Coalition of Israeli right-wing political parties. It was  created by the 1973 merger of the Herut Party (1948) and the Liberal Party  (1961), which itself was a merger of the General Zionists and the Pro�  gressives. From the late 1970s Likud alternated in power with the Israel  Labour Party. Likud generally was considered more skeptical than Labour  of the peace process with the Palestinians and Israel�s Arab neighbours,  but when in power some Likud prime ministers made dramatic conces�  sions on both fronts. Party leaders have included Menachem Begin, Yitzhak  Shamir, and Ariel Sharon.

Lilacs have deep  green leaves and large, oval clusters of compound blooms coloured deep  purple, lavender, blue, red, pink, white, or creamy yellow; they are often  highly fragrant. The common lilac (S. vulgaris ) reaches 20 ft (6 m) in  height and produces many suckers (shoots from the stem or root). The  name syringa was formerly used for the mock orange of the saxifrage  family, and the butterfly bush (see buddleia) is commonly called �summer  lilac.�</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1114 I Lilburne &gt; limbo</p><p>L_</p><p>N</p><p>Lilburne, John (b. 1614?, Greenwich, near London, Eng.�d.

His grammar, which actually consisted of  two books, one in English and the other in Latin, first appeared about 18  years after his death. Its use by royal order in all English grammar schools  won it the name �the King�s Grammar.� With corrections and revisions,  it continued to be used as late as the 19th century and influenced genera�  tions of English people�s views of all languages, including English.</p><p>lily family Family Liliaceae (order Liliales), which contains about  4,000 species of flowering herbs and shrubs in 280 genera. The genus  Lilium includes the true lilies. Native primarily to temperate and subtropi�  cal regions, these monocots (see cotyledon) usually have six-segmented  flowers, three-chambered capsular fruits, and leaves with parallel veins.  Among the oldest cultivated plants, true lilies are erect perennials with  leafy stems, scaly bulbs, usually narrow leaves, and solitary or clustered  flowers, some quite fragrant, in a variety of colours. Most species store  nutrients underground in a bulb, corm, or tuber. Important garden orna�  mentals and houseplants in the family include aloe, bluebell, crocus, day-  lily, hosta, Solomon's seal, and tulip. Food-producing members include  ONION, GARLIC, and ASPARAGUS.</p><p>lily of the valley Fragrant perennial herb and sole species ( Conval-  laria majalis ) of the genus Convallaria (lily family), native to Eurasia and  eastern North America.

It is located inland from the Pacific Ocean  port of Callao and near the Andes Mountains. Its nickname, El Pulpo  (�The Octopus�), refers to its sprawling metropolitan area. It was founded  by Francisco Pizarro in 1535 on the feast of the Epiphany, prompting the  name Ciudad de los Reyes (�City of Kings�), but the name never took.  Lima later became the capital of the Viceroyalty of Peru. The city was  destroyed by an earthquake in 1746 but was rebuilt. It grew rapidly dur�  ing the 20th century and now accounts for nearly one-third of Peru�s total  population. It is the country�s economic and cultural centre.

The district is primarily agricultural.</p><p>limb darkening In astrophysics, the gradual decrease in observed  brightness of the disk of a star from its centre to its edge (limb). This  phenomenon, readily apparent in photographs of the Sun, occurs because  the solar atmosphere�s temperature increases with depth. Looking at the  Sun�s centre, an observer sees the deepest, hottest layers, which emit the  most light. At the limb, only the upper, cooler layers, which produce less  light, are visible. Observations of solar limb darkening are used to deter�  mine the temperature structure of the Sun�s atmosphere.</p><p>limbo In Roman Catholicism, a region between heaven and hell, the dwell�  ing place of souls not condemned to punishment but deprived of the joy  of existence with God in heaven.

MOO-  1416) Flemish illuminators. Sons of a sculptor, the three brothers�Pol,  Herman, and Jehanequin de Limbourg�learned the goldsmith�s art in  Paris and entered the service of the duke de Berry, for whom they pro�  duced one of the most famous of all illuminated manuscripts, a book of hours  (private prayer book) known as the Tres riches heures du due de Berry  (c. 1410-16). Since the brothers worked together, it is difficult to distin�  guish individual styles. They synthesized the achievements of their con�  temporaries into a style characterized by tall, aristocratic figures with  lavish, curvilinear draperies and by highly naturalistic seasonal landscapes  and scenes of peasant life. Their art did much to determine the course of  early Netherlandish art. Their deaths in the same year suggest that they  died of plague.</p><p>lime Small shrublike tree ( Citrus aurantifolia ), widely grown in tropi�  cal and subtropical areas, and its  edible acidic fruits. Stiff branches  and twigs leave the thorny stem at  irregular intervals and end in green  leaves. Clusters of small white flow�  ers produce small oval fruits with a  thin, pale greenish yellow rind. The  juicy pulp is more acidic and sweet  than that of the lemon. Limes are  used to flavour many foods. High in  vitamin C, they were formerly used  in the British navy to prevent scurvy;  hence the nickname �Limey� for  British sailors.</p><p>lime or quicklime or calcium  oxide Inorganic compound, white  or grayish white solid, chemical for�  mula CaO, made by roasting limestone (calcium carbonate, CaC0 3 ) until  all the carbon dioxide (C0 2 ) is driven off. One of the four most impor�  tant basic chemical commodities, it is used as a refractory, as a flux in  steel manufacture, as a C0 2 absorbent, to remove contaminants from stack  gases, to neutralize various acids, in pulp and paper, in insecticides and  fungicides, in sewage treatment, and in the manufacture of glass, calcium  carbide, and sodium carbonate. Adding water to lime yields calcium  hydroxide (slaked lime, calcium hydrate, hydrated lime, or caustic lime),  which is used in mortar, plasters, cements, whitewash, hide dehairing, and  water softening and purification and as a source of other calcium salts.</p><p>limelight Early form of theatrical lighting. The incandescent calcium  light invented by Thomas Drummond in 1816 was first employed in a  theatre in 1837 and was widely used by the 1860s. Its soft, brilliant light  enabled it to be focused for spotlighting and to create effects such as sun�  light and moonlight. The expression �in the limelight� referred to the most  desirable acting area on the stage, the front and centre, which was illu�  minated by limelights. Electric lighting replaced limelight in the late 19th  century.</p><p>limerick Popular form of short, humorous verse, often nonsensical and  frequently ribald. It consists of five lines, rhyming aabba, and the domi�  nant metre is anapestic, with two feet in the third and fourth lines and  three feet in the others. The origin of the term is obscure, but a group of  poets in County Limerick, Ire., wrote limericks in Irish in the 18th cen�  tury. The first collections in English date from c. 1820. Among the most  famous are those in Edward Lear�s Book of Nonsense (1846).</p><p>limes Vle-mas\ plural limites Latin "path" In ancient Rome, a strip  of open land along which troops advanced into unfriendly territory. It  came to mean a Roman military road, fortified with watchtowers and forts.  An example of this construction was the continuous system of fortifica�  tions and barriers extending 345 mi (555 km) along the Roman frontier  in Germany and Raetia. Hadrian's Wall also served as a limes. Though not  impenetrable, the limites allowed the Romans to control communications  along frontiers and deterred raiding parties. In the eastern and southern  empire, limites were often used to guard caravan routes.</p><p>limestone Sedimentary rock composed mainly of calcium carbonate  (CaC0 3 ), usually in the form of calcite and, less commonly, aragonite. It  may contain considerable amounts of magnesium carbonate (dolomite) as  well. Most limestones have a granular texture; in many cases, the grains  are tiny fragments of fossil animal shells. Much knowledge of the Earth�s  history has been derived from the study of fossils embedded in limestone  and other carbonate rocks. Limestone is used as a soil conditioner, in the  manufacture of glass, and in agriculture. Ornamental varieties are used  for flooring, exterior and interior facings of buildings, and monuments.</p><p>Limfjorden Vlem-.fyor-donN Strait across northern Jutland, Denmark,  connecting the North Sea and the Kattegat. It is 110 mi (180 km) long  and is actually a series of fjords dotted with islands. In 1825 the North  Sea broke through the western part, and the Thybor0n Kanal was cut to  keep the outlet open.</p><p>limit Mathematical concept based on the idea of closeness, used mainly  in studying the behaviour of functions close to values at which they are  undefined. For example, the function \/x is not defined at x = 0. For posi�  tive values of x, as x is chosen closer and closer to 0, the value of l/x  begins to grow rapidly, approaching infinity as a limit. This interplay of  action and reaction as the independent variable moves closer to a given  value is the essence of the idea of a limit. Limits provide the means of  defining the derivative and integral of a function.</p><p>limitations, statute of Legislative act restricting the time within  which legal proceedings may be brought, usually to a fixed period after  the occurrence of the events that gave rise to the cause of action. Such  statutes are enacted to protect persons against claims made after evidence  has been lost, memories have faded, or witnesses have disappeared. The  periods prescribed for different actions in different jurisdictions vary con�  siderably.</p><p>limited liability Condition under which the loss that an owner (share�  holder) of a business may incur is limited to the capital invested in the  business and does not extend to personal assets. The forerunners of  limited-liability companies were limited partnerships, which were com�  mon in Europe and the U.S. in the 18th and early 19th centuries. In lim�  ited partnerships, one partner is entirely liable for losses and the other  partners are liable only for the amounts they invested in the business. After  the Joint-Stock Companies Act (1844) in England made incorporation  easier, joint-stock companies with limited liability for all members  became widespread. The development of the limited-liability company  was crucial to the rise of large-scale industry in the late 19th and 20th  centuries, since it enabled businesses to mobilize capital from a variety of  investors who were unwilling to risk their entire personal fortunes in their  investments.

Faience of undistinguished quality was pro�  duced there from 1736, but the manufacture of hard-paste, or true, por�  celain dates only from 1771. In 1784 the factory was acquired as an  adjunct of the royal factory at Sevres (see Sevres porcelain), and the deco�  rations of the two wares became similar.

The capital is  Limoges (pop., 1999: 133,960). Originally inhabited by the ancient Gal�  lic tribe of Lemovices, the region was conquered by Rome c. 50 bc. Under  the Carolingians, it was part of Aquitaine. On Eleanor of Aquitaine�s mar�  riage to King Henry II of England in 1152, it passed to English control.

The daughter of intellectuals who had fled China in 1948, she  achieved fame in 1981 when her class assignment at Yale University won  the nationwide Vietnam Veterans Memorial competition. Lin�s award�  winning design consisted of a polished black granite V-shaped wall  inscribed with the names of the approximately 58,000 men and women  who were killed or missing in action; the abstract nature of the design  aroused a great deal of controversy. Her subsequent, vastly different</p><p>European limpets (Patella vulgata) with  acorn barnacles (Balanus balanoides)</p><p>NEVILLE FOX-DAVIES�BRUCE COLEMAN INC./EB INC.</p><p>designs include the major commissions for the Civil Rights Memorial in  Montgomery, Ala.

Sept. 13, 1971?, Mongolia?) Chinese military leader  and government official who played a prominent role in the Cultural Revo�  lution. He joined the Socialist Youth League in 1925 and Chiang Kai-shek�s  Northern Expedition in 1926. When Chiang turned on the communists in  1927, Lin fled to join Mao. During the Long March Lin became legend�  ary for never losing a battle, and he prevailed against the Japanese in the  1930s and the Nationalists in the 1940s. In the early 1960s his reforma�  tion and indoctrination of the army in accordance with Mao�s teachings  became a model for the rest of society, and during the Cultural Revolu�  tion he was designated Mao�s successor. Subsequent events are unclear,  but in September 1971 the Chinese government reported that Lin died in  a plane crash in Mongolia in an attempt to flee China; his death has  remained a mystery.</p><p>Lin Yutang or Lin Yu-t'ang (b. Oct. 10, 1895, Longxi, Fujian prov�  ince, China�d. March 26, 1976, Hong Kong) Chinese writer. The son of  a Presbyterian minister, he studied in the U.S. and Europe. In 1932 he  established a highly successful Western-style satirical magazine of a type  totally new to China; soon he introduced two other publications. A pro�  lific writer of works in Chinese and English, he produced his first English-  language book. My Country and My People, in 1935. From 1936 he lived  chiefly in the U.S. His other works include The Wisdom of China and  India (1942), books on Chinese history and philosophy, and highly  acclaimed English translations of Chinese literary masterpieces.</p><p>Lin Zexu Vlin-'dzo-'shiA or Lin Tse-hsu (b.

Lin passed the highest examination in the Chinese  examination system and entered the Hanun Academy and government.  Having suggested to the emperor ways to suppress the opium trade, Lin  found himself appointed imperial commissioner and dispatched to Guang�  zhou (Canton) to deal with the problem directly. He was so successful that,  in retaliation for his destruction of their opium stocks, the British ravaged  large parts of southern China, and Lin was quickly dismissed. He served  loyally at his post of exile and was soon called back to important service.  He died on his way to help suppress the Taping Rebellion.</p><p>linac See linear accelerator</p><p>Linacre Vli-ni-korV Thomas (b. c. 1460, Canterbury, Kent, Eng.�d.

It is a market centre for an agricultural region and also possesses  some manufacturing. It has many medieval buildings, including the cathe�  dral (begun c. 1075).</p><p>Lincoln, Abraham (b. Feb. 12, 1809, near Hodgenville, Ky., U.S.�d.  April 15, 1865, Washington, D.C.) 16th president of the U.S. (1861-65).  Born in a Kentucky log cabin, he moved to Indiana in 1816 and to Illi�  nois in 1830. After working as a storekeeper, a rail-splitter, a postmaster,  and a surveyor, he enlisted as a volunteer in the Black Hawk War (1832)  and was elected captain of his company. He taught himself law and, hav�  ing passed the bar examination, began practicing in Springfield, Ill., in  1836. As a successful circuit-riding lawyer from 1837, he was noted for  his shrewdness, common sense, and honesty (earning the nickname �Hon�  est Abe�). From 1834 to 1840 he served in the Illinois state legislature,  and in 1847 he was elected as a Whig to the U.S. House of Representa�  tives. In 1856 he joined the Republican Party, which nominated him as  its candidate in the 1858 Senate election. In a series of seven debates with  Stephen A. Douglas (the Lincoln-Douglas Debates), he argued against the  extension of slavery into the territories. Though morally opposed to sla�  very, he was not an abolitionist; indeed, he attempted to rebut Douglas�s  charge that he was a dangerous radical, by reassuring audiences that he  did not favour political equality for blacks. Despite his loss in the elec�  tion, the debates brought him national attention. In the 1860 presidential  election, he ran against Douglas again and won by a large margin in the  electoral college, though he received only two-fifths of the popular vote.  The South opposed his position on slavery in the territories, and before  his inauguration seven Southern states had seceeded from the Union. The  ensuing American Civil War completely consumed Lincoln�s administra�  tion. He excelled as a wartime leader, creating a high command for direct�  ing all the country�s energies and resources toward the war effort and  combining statecraft and overall command of the armies with what some  have called military genius. However, his abrogation of some civil liber�  ties, especially the writ of habeas corpus, and the closing of several news�  papers by his generals disturbed both Democrats and Republicans,  including some members of his own cabinet. To unite the North and  influence foreign opinion, he issued the Emancipation Proclamation (1863);  his Gettysburg Address (1863) further ennobled the war�s purpose. The  continuing war affected some Northerners� resolve and his reelection was  not assured, but strategic battle victories turned the tide, and he easily  defeated George B. McClellan in 1864. His platform included passage of  the 13th Amendment outlawing slavery (ratified 1865). At his second  inaugural, with victory in sight, he spoke of moderation in reconstruct�  ing the South and building a harmonious Union. On April 14, five days  after the war ended, he was shot and mortally wounded by John Wilkes  Booth.</p><p>Lincoln, Benjamin (b. Jan. 24, 1733, Hingham, Mass.�d. May 9,  1810, Boston) American Revolutionary officer. After serving in the Mas�  sachusetts militia (1755-76), he was appointed major general in the Con�  tinental Army. As commander of forces in the South in 1780, he was  forced to surrender with 7,000 troops after the British victory at Charles�  ton, S.C. Released in a prisoner exchange, he served in the Yorktown  campaign in 1781. From 1781 to 1783 he served as secretary of war, and  in 1787 he commanded the militia forces that suppressed Shays' Rebellion.  From 1789 to 1809 he was collector for the port of Boston.</p><p>Lincoln Center for the Performing Arts Travertine-clad cultural  complex on the western side of Manhattan (1962-68), built by a board of  architects headed by Wallace K. Harrison (1895-1981). The buildings,  situated around a plaza with a fountain, are the home of the Metropolitan  Opera, the New York City Opera, the New York Philharmonic, the New  York City Ballet, and the Juilliard School. Harrison himself designed the  Metropolitan Opera building, and Eero Saarinen designed the Vivian Beau�  mont Theater. Philip Johnson�s New York State Theater incorporates a Clas�  sical facade and a four-story lobby. Johnson also rebuilt Avery Fisher Hall  (home of the New York Philharmonic), originally designed by Max Abra-  movitz, to correct acoustic deficiencies and improve the lobby spaces.</p><p>Lincoln-Douglas Debates Series of seven debates between Repub�  lican candidate Abraham Lincoln and Democratic Sen. Stephen A. Douglas  in the 1858 Illinois senatorial campaign. They focused on slavery and its  extension into the western territories. Lincoln criticized Douglas for his</p><p>support of popular sovereignty and the Kansas-Nebraska Act, while Dou�  glas accused Lincoln of advocating racial equality and disruption of the  Union. Douglas won reelection, but Lincoln�s antislavery position and  oratorical brilliance made him a national figure in the young Republican  Party.</p><p>Lincolnshire Vliq-kon-.shM Administrative (pop., 2001: 646,646), geo�  graphic, and historic county, eastern England. It lies along the North Sea  from the Humber estuary to the Wash. Among its most important towns  is Lincoln. Inhabited in prehistoric times, it developed as an area of Roman  settlement. Anglo-Saxons later established the kingdom of Lindsey. Dan�  ish influence was also widespread through villages established by Danes.  Geographically isolated, it remains primarily an agricultural region. Along  the coast, tourism has grown.</p><p>Lind, James (b. 1716, Edinburgh, Scot.�d. July 13, 1794, Gosport,  Hampshire, Eng.) Scottish naval surgeon and physician. Having observed  thousands of scurvy, typhus, and dysentery cases and the shipboard condi�  tions that caused them, he published A Treatise on Scurvy in 1754, a time  when scurvy killed more British sailors than combat. He recommended  giving citrus fruits and juices (sources of vitamin C) to sailors on long  voyages, a practice known to the Dutch for nearly two centuries. When  the practice was fully instituted in 1795, scurvy disappeared from the  ranks �as if by magic.� Lind also suggested shipboard delousing and use  of hospital ships, and he arranged for distillation of seawater for drink�  ing.</p><p>Lind, Jenny orig. Johanna Maria Lind (b. Oct. 6, 1820, Stock�  holm, Swed.�d. Nov. 2, 1887, Malvern, Worcestershire, Eng.) Swedish  soprano. She became prima donna at the Royal Opera in Stockholm at  age 18. Study with Manuel Garcia (1805-1906) in 1841 averted damage  from vocal strain. Her career expanded to Germany, then to Vienna and  London, where she created a sensation. Her European fame caught the  eye of P.T. Barnum, who arranged a U.S. tour (dubbing her �the Swedish  Nightingale�) that launched many modern publicity techniques. She left  Barnum in 1851 and resumed singing in Europe, though much less fre�  quently. In her later years she lived and taught in England.</p><p>Lindbergh, Charles A(ugustus) (b. Feb. 4, 1902, Detroit, Mich.,  U.S.�d. Aug. 26, 1974, Maui,</p><p>Hawaii) Aviator who made the first  nonstop solo flight across the Atlan�  tic Ocean. He left college to enroll in  army flying schools and became an  airmail pilot in 1926. He obtained  backing from St. Louis businessmen  to compete for a prize for flying from  New York to Paris, and in 1927 in the  monoplane Spirit of St. Louis he  made the flight in 33.5 hours, becom�  ing an instant hero in the U.S. and  Europe. In 1929 he married the  writer Anne Morrow (1906-2001),  who would later serve as his copilot  and navigator. In 1932 their child  was kidnapped and murdered, a  crime that received worldwide atten�  tion. They moved to England to  escape the publicity, returning to the  U.S. in 1940 to criticism over his speeches calling for U.S. neutrality in  World War II. During the war Lindbergh was an adviser to Ford Motor  Company and United Aircraft Corporation. After the war he was a con�  sultant to Pan American Airways and the U.S. Department of Defense  and served on many aeronautical boards and committees. In 1953 he wrote  the Pulitzer Prize-winning The Spirit of St. Louis.</p><p>linden Any of about 30 species of trees that make up the genus Tilia  (family Tiliaceae), native to the Northern Hemisphere.

U.S. playwright, actor, and producer known  for his collaboration with Russel Crouse (1893-1966). Lindsay began his  career as an actor, director, and playwright, and Crouse was a journalist  before they were paired by producer Vinton Freedley to write librettos for  the successful Cole Porter musicals Anything Goes (1934) and Red, Hot  and Blue (1936). Their most popular play, Life with Father (1939), ran  for over seven years and starred Lindsay as Father. They produced Arsenic  and Old Lace (1940) and later wrote librettos for musicals such as State  of the Union (1945, Pulitzer Prize) and The Sound of Music (1959).</p><p>Lindsay, (Nicholas) Vachel (b. Nov. 10, 1879, Springfield, Ill.,  U.S.�d. Dec. 5, 1931, Springfield) U.S. poet. In his youth, he began  traveling the country reciting his poems in return for food and shelter, in  an attempt to revive poetry as an oral art form of the common people. He  first received widespread recognition for �General William Booth Enters  into Heaven� (1913), about the founder of the Salvation Army. His works  are full of powerful rhythms, vivid imagery, and bold rhymes and express  an ardent patriotism, a passion for progressive democracy, and a roman�  tic view of nature. His collections include Rhymes to Be Traded for Bread  (1912), The Congo (1914), and The Chinese Nightingale (1917). He was  responsible for discovering the work of Langston Hughes. Depressed and  unstable in later years, he committed suicide by drinking poison.</p><p>line Basic element of Euclidean geometry. Euclid defined a line as an inter�  val between two points and claimed it could be extended indefinitely in  either direction. Such an extension in both directions is now thought of  as a line, while Euclid�s original definition is considered a line segment.  A ray is part of a line extending indefinitely from a point on the line in  only one direction. In a coordinate system on a plane, a line can be rep�  resented by the linear equation ax + by + c = 0. This is often written in  the slope-intercept form as y = mx + b, in which m is the slope and b is  the value where the line crosses the y-axis. Because geometrical objects  whose edges are line segments are completely understood, mathemati�  cians frequently try to reduce more complex structures into simpler ones  made up of connected line segments.</p><p>line integral In mathematics, the integral of a function of several vari�  ables defined on a line or curve that has been expressed in terms of arc  length (see length of a curve). An ordinary definite integral is defined over  a line segment, whereas a line integral may use a more general path, such  as a parabola or a circle. Line integrals are used extensively in the theory  of functions of a complex variable.</p><p>Line Islands Chain of islands, central Pacific Ocean, south of the  Hawaiian Islands.

Kiribati also holds  the central group (Malden and Starbuck islands) and the southern group  (Vostok and Flint islands and Caroline Atoll).</p><p>Linear A and Linear B Linear forms of writing used by Aegean civi�  lizations during the 2nd millennium bc. Examples of Linear A, a syllabary  (a writing system in which one character represents a whole syllable)  written from left to right, date from 1850 bc to 1400 bc. The language  written in Linear A remains unknown. Linear B, adapted from Linear A,  was borrowed from the Minoan civilization by the Mycenaean Greeks,  probably c. 1600 bc, and used to write the Mycenaean Greek dialect.  Examples of Linear B script have been found on clay tablets and vases</p><p>from c. 1400-1200 bc. These texts represent the oldest known form of  Greek. Linear B was deciphered as Greek in 1952 by Michael Ventris and  John Chadwick.</p><p>linear accelerator or linac Type of particle accelerator that imparts  a series of relatively small increases in energy to subatomic particles as  they pass through a sequence of alternating electric fields set up in a lin�  ear structure. The small accelerations add together to give the particles a  greater energy than could be achieved by the voltage used in one section  alone. One of the world�s longest linacs is the 2-mi (3.2-km) machine at  the Stanford Linear Accelerator Center, which can accelerate electrons to  energies of 50 billion electron volts. Much smaller linacs, both proton and  electron types, have important practical applications in medicine and  industry.</p><p>linear algebra Branch of algebra concerned with methods of solving  systems of linear equations; more generally, the mathematics of linear  transformations and vector spaces. �Linear� refers to the form of the equa�  tions involved�in two dimensions, ax + by = c. Geometrically, this rep�  resents a line. If the variables are replaced by vectors, functions, or  derivatives, the equation becomes a linear transformation. A system of equa�  tions of this type is a system of linear transformations. Because it shows  when such a system has a solution and how to find it, linear algebra is  essential to the theory of mathematical analysis and differential equations.  Its applications extend beyond the physical sciences into, for example,  biology and economics.</p><p>linear approximation In mathematics, the process of finding a  straight line that closely fits a curve (function) at some location. Expressed  as the linear equation y = ax + b, the values of a and b are chosen so that  the line meets the curve at the chosen location, or value of x, and the slope  of the line equals the rate of change of the curve (derivative of the func�  tion) at that location. For most curves, linear approximations are good  only very close to the chosen x. Yet much of the theory of calculus,  including the fundamental theorem of calculus and the mean-value theorem  for derivatives, is based on such approximations.</p><p>linear programming Mathematical modeling technique useful for  guiding quantitative decisions in business, industrial engineering, and to  a lesser extent the social and physical sciences. Solving a linear program�  ming problem can be reduced to finding the optimum value (see optimi�  zation) of a linear equation (called an objective function), subject to a set  of constraints expressed as inequalities. The number of inequalities and  variables depends on the complexity of the problem, whose solution is  found by solving the system of inequalities like a system of equations. The  extensive use of linear programming during World War II to deal with  transportation, scheduling and allocations of resources under constraints  like cost and priority gave the subject an impetus that carried it into the  postwar era. The number of equations and variables needed to model  real-life situations accurately is large, and the solution process can be  time-consuming even with computers. See also simplex method.</p><p>linear transformation In mathematics, a rule for changing one geo�  metric figure (or matrix or vector) into another using a formula with a  specified format. The format must be a linear combination, in which the  original components (e.g., the x and y coordinates of each point of the  original figure) are changed via the formula ax + by to produce the coor�  dinates of the transformed figure. Examples include flipping the figure  over the x or y axis, stretching or compressing it, and rotating it. Every  such transformation has an inverse, which undoes its effect.</p><p>linen Fibre, yarn, and fabric made from the flax plant. Flax is one of the  oldest textile fibres used by humans; evidence of its use has been found in  Switzerland�s prehistoric lake dwellings. Fine linen fabrics have been  discovered in ancient Egyptian tombs. The fibre is obtained by subject�  ing plant stalks to a series of operations, including retting (a fermentation  process), drying, crushing, and beating. Linen is stronger than cotton,  dries more quickly, and is more slowly affected by exposure to sunlight.  Low elasticity, imparting a hard, smooth texture, makes linen subject to  wrinkling. Because linen absorbs and releases moisture quickly and is a  good conductor of heat, linen garments feel cool to wearers. Fine grades  of linen are made into woven fabrics and laces for apparel and household  furnishings.</p><p>linga or I ingam In Hinduism, the symbol of the god Shiva and of gen�  erative power.

Historically, the linga was  a representation of the phallus, as  sculptures from the lst-2nd century  ad, the earliest dates of linga wor�  ship, make clear, and most modern  Hindus think of it in these terms. The  stylization of the linga as a smooth  cylindrical mass asserts an aniconic  meaning. A sexual dimension  remains in the most common form in  which the linga appears today. The  yoni, symbol of the female sex organ,  often forms the base of the linga, a  reminder that the male and female  principles together represent the  totality of existence. The linga is  worshiped with offerings of flowers,  water, fruit, leaves, and rice; the  purity of the materials and the clean�  liness of the worshiper are particu�  larly stressed.</p><p>Lingayat Vliq-gg-yotX Member of  a Hindu sect that worships Shiva as  the only deity. It has a wide follow�  ing in southern India. Its followers  take their name (�linga-wearers�)  from the small UNGAS that both men  and women wear on a cord around  the neck. The Lingayats� belief in a  single deity and their concept of  bhakti (devotion) as an intuitive and  loving knowledge of God show the  influence of Ramanuja. They reject  Brahma and the authority of the  Vedas; their opposition to child mar�  riage and the ill-treatment of widows  anticipated the social reform move�  ments of the 19th century.</p><p>Lingayen Uiq-ga-'yenX Gulf  Inlet, South China Sea, northwestern  coast of Luzon, Philippines.

A lingua franca may also be a  pidgin, like Melanesian Pidgin, widely used in the southern Pacific. The  term lingua franca (Latin: �Frankish language�) was first applied to a pid�  gin based on French and Italian developed in the Mediterranean. See also  CREOLE.</p><p>linguistics Study of the nature and structure of language. It tradition�  ally encompasses semantics, syntax, and phonology. Synchronic linguistic  studies aim to describe a language as it exists at a given time; diachronic  studies trace a language�s historical development. Greek philosophers in  the 5th century bc who debated the origins of human language were the  first in the West to be concerned with linguistic theory. The first complete  Greek grammar, written by Dionysus Thrax in the 1st century bc, was a  model for Roman grammarians, whose work led to the medieval and  Renaissance vernacular grammars.</p><p>With the rise of historical linguistics in the 19th century, linguistics  became a science. In the late 19th and early 20th centuries Ferdinand de  Saussure established the structuralist school of linguistics (see structural�  ism), which analyzed actual speech to learn about the underlying structure  of language. In the 1950s Noam Chomsky challenged the structuralist pro�  gram, arguing that linguistics should study native speakers� unconscious  knowledge of their language (competence), not the language they actu�  ally produce (performance). His general approach, known as transforma�  tional generative grammar, was extensively revised in subsequent decades  as the extended standard theory, the principles-and-parameters  (government-binding) approach, and the minimalist program. Other gram�  matical theories developed from the 1960s were generalized phrase struc�  ture grammar, lexical-functional grammar, relational grammar, and  cognitive grammar. Chomsky�s emphasis on linguistic competence  greatly stimulated the development of the related disciplines of psychol�  inguistics and neurolinguistics. Other related fields are anthropological  linguistics, computational unguistics, mathematical linguistics, sociolinguis�  tics, and the philosophy of language.</p><p>linguistics, historical Branch of linguistics concerned with examin�  ing changes in phonology, grammar, and semantics during a language�s  evolution, reconstructing earlier stages, and uncovering evidence of the  influence of other languages. Its roots are in Classical and medieval writ�  ings on etymology and in the comparative study of Greek and Latin dur�  ing the Renaissance. Only in the 19th century did more scientific  language-analysis methods lead to the development of historical linguis�  tics as a scholarly discipline. The Neogrammarians, a group of German  linguists who formulated sound correspondences in the Indo-European  languages, were especially influential. In the 20th century the methods of  historical linguistics were extended to other language groups.</p><p>linkage In mechanical engineering, a system of solid, usually metallic,  links (bars) connected to two or more other links by pin joints (hinges),  sliding joints, or ball-and-socket joints to form a closed chain or a series  of closed chains. When one link is fixed, the possible movements of the  other links relative to the fixed link and to one another depend on the  number of links and the number and types of joints. With four pin-  connected links, for example, the links all move in parallel planes, and  regardless of which link is fixed, the others move in a fixed way relative  to the fixed link. With various relative lengths of the links, this four-bar  linkage becomes a useful mechanism for converting uniform rotary to  non-uniform rotary motion or continuous rotary to oscillatory motion. It  is the most commonly used linkage mechanism in machine construction.</p><p>linkage group All the genes on a single chromosome. They are inher�  ited as a group; during cell division they act and move as a unit rather  than independently. Variations in linkage groups can occur if a chromo�  some breaks, and the sections join with the partner chromosome if it has  broken in the same places. This exchange of genes between chromosomes,  called crossing-over, usually occurs during meiosis. Sex linkage is the ten�  dency of a characteristic to be linked to one sex; sex-linked traits in  humans include red-green colour blindness and hemophilia.</p><p>Linkletter, Artfhur Gordon) (b.

It was pat�  ented in 1884 by Ottmar Mergenthaler. It has now been almost entirely  supplanted by photocomposition. In Linotype, a keyboard is manipulated  to compose each line of text. The slugs produced by the machine are rect�  angular solids of type metal (an alloy of lead, antimony, and tin) with  raised characters that are a mirror image of the desired printed line. After  hot-metal casting, the slug of type, air-cooled briefly, is placed in a �stick�  for insertion in the proper position into the press form being made up.

In 1991 Linus Torvalds of Finland began asking for volunteer pro�  grammers over the Internet to collaborate on the development of a UNIX-  like OS for personal computers; the �1.0� release of Linux was in 1994. A  true multiuser, multitasking system, Linux contained features (e.g., vir�  tual memory, shared libraries, memory management, and TCP/IP net�  working) formerly only found on mainframe computers. With its source  code freely available, thousands of volunteers, as well as several compa�  nies that sell prepackaged Linux products, have contributed to the OS.

Lions inhabit grassy  plains and open savanna. The male  is 6-7 ft (1.8-2.1 m) long, excluding  the 3-ft (1-m) tail, stands about 4 ft  (1.2 m) high at the shoulder, and  weighs 370-500 lbs (170-230 kg).</p><p>The female, or lioness, is consider�  ably smaller. The male�s coat is usu�</p><p>ally buff yellow or orange-brown; lionesses are more consistently tawny  or sandy. The male�s outstanding characteristic is his mane. Lions are  unique among cats in that they live in a group, or pride, often consisting  of about 15 individuals. Lionesses are the chief hunters. They prey on  animals of all sizes, including hippopotamuses, but prefer wildebeests,  antelopes, and zebras. After eating, a lion may rest for a week.</p><p>Lion, Gulf of Gulf of the Mediterranean Sea, extending along the coast  of southern France from the Spanish border to Toulon.

Lionfish  have enlarged pectoral fins and elongated dorsal fin spines, and each spe�  cies bears a particular pattern of bold stripes. When disturbed, the fish  spread and display their fins, and, if further pressed, present and attack  with the dorsal spines. Pterois volitans, sometimes kept by fish fanciers,  is striped with red, brown, and white and grows to about 12 in. (30 cm)  long. Several smaller Indo-Pacific species of the genus Dendrochirus are  also known as lionfish.</p><p>Lions Clubs, International Association of Civilian service club.

One of the three large  classes of substances in foods and living cells, lipids contain more than  twice as much energy (calories) per unit of weight as the other two (pro�  teins and carbohydrates). They include the fats and edible oils (e.g., but�  ter, olive oil, corn oil), which are primarily triglycerides; phospholipids  (e.g., lecithin), which are important in cell structure and metabolism; WAXes  of animal or plant origin; and sphingolipids, complex substances found  in various tissues of the brain and nervous system. Since insolubility is  the defining characteristic, cholesterol and related steroids, carotenoids  (see carotene), prostaglandins, and various other compounds are also clas�  sifiable as lipids.</p><p>lipid storage disease Any of a group of relatively rare hereditary  disorders of fat metabolism in which enzyme defects cause distinctive types  of lipids to accumulate.

It lay between the Teutoburg Forest  and the Weser River, and its capital was Detmold. A lordship in medieval  times, it became a county in the 16th century. Dynastic divisions in the  early 17th century resulted in two counties, Lippe and Schaumburg-Lippe.  In 1720 it was made a principality. A member of the German Confedera�  tion in 1815, it became part of the German Empire in 1871 and of the  Weimar Republic in 1918. In 1947 it was incorporated into North Rhine-  Westphalia.</p><p>Lippe River River, western Germany. Rising on the western edge of the  Teutoburg Forest, it follows a westerly course of 155 mi (250 km) and  enters the Rhine River near Wesel.

April 18,  1504, Florence) Italian painter. After the death of his father, Fra Filippo  Lippi, when Filippino was 12, he entered the workshop of Sandro Botticelli  and absorbed many aspects of his style. One of his most important assign�  ments was the completion of the frescoes in the Brancacci Chapel in Flo�  rence�s Santa Maria del Carmine (c. 1485-87), left unfinished when  Masaccio died. His most popular painting is the Vision of St. Bernard  altarpiece (c. 1480). His highly decorative frescoes in the Carafa Chapel  in Santa Maria sopra Minerva, Rome (1488-93), and those in the Strozzi  Chapel in Santa Maria Novella, Florence (completed 1502), anticipated  Tuscan Mannerism of the 16th century.</p><p>Lippi, Fra Filippo (b. c. 1406, Florence�d. Oct. 8/10, 1469, Spoleto,  Papal States) Italian painter. In 1421  he became a Carmelite monk at  Santa Maria del Carmine in Flo�  rence, where Masaccio was soon  decorating the Brancacci Chapel  with frescoes. Lippi himself painted  frescoes in the church, much influ�  enced by Masaccio�s, then disap�  peared from the monastery in 1432.</p><p>In 1434 he was in Padua, but in 1437  he returned to Florence under the  protection of the Medici family and  was commissioned to execute sev�  eral works for convents and  churches. His Madonna and Child  (1437) and Annunciation (c. 1442)  show a maturing style characterized  by warm colouring and attention to  decorative effects. Later critics have  recognized in Lippi a �narrative�  spirit that reflected the life of his  time and translated into everyday  terms the ideals of the early Renais�  sance. In 1456, while painting in a  convent in Prato, he fled with one of  the nuns, Lucrezia Buti. The couple was later released from their indi�  vidual vows and permitted to marry, and from that union was born the  illustrious Filippino Lippi. The former friar returned often to Prato, and his  frescoes in the cathedral there stand among his finest achievements.</p><p>Lippmann, Walter (b. Sept. 23, 1889, New York, N.Y., U.S.�d.

Alcohol content ranges from  24% to 60% by volume, and flavourings include fruits, nuts, herbs, spices,  and such ingredients as coffee and chocolate. Liqueurs were probably first  produced commercially by medieval monks and alchemists. Sweet and  containing ingredients that promote digestion, they are popular as after-  dinner drinks and are also used in mixed drinks and dessert dishes. Vari�  eties include apricot liqueur, creme de menthe (mint-flavoured), Curasao  (with green orange peel, from Curasao), and proprietary brands such as  Benedictine (an herb liqueur), Grand Marnier (an orange liqueur from  France�s Cognac region), Irish Mist (flavoured with Irish whiskey and  honey), and Kahlua (coffee-flavoured).</p><p>liquid One of the three principal states of matter, intermediate between  a gas and a solid. A liquid has neither the orderliness of a solid nor the  randomness of a gas. Liquids have the ability to flow under the action of  very small shear STRESSes. Liquids in contact with their own vapour or air  have a surface tension that causes the interface to assume the configura�  tion of minimum area (i.e., spherical). Surfaces between liquids and sol�  ids have interfacial tensions that determine whether the liquid will wet  the other material. With the exception of liquid metals, molten salts, and  solutions of salts, the electrical conductivities of liquids are small.</p><p>liquid crystal Substance that flows like a liquid but maintains some of  the ordered structure characteristic of a crystal. Some organic substances  do not melt directly when heated but instead turn from a crystalline solid  to a liquid crystalline state. When heated further, a true liquid is formed.  Liquid crystals have unique properties. The structures are easily affected  by changes in mechanical stress, electromagnetic fields, temperature, and  chemical environment. See also liquid crystal display.</p><p>liquid crystal display (LCD) Optoelectronic device used in displays  for watches, calculators, notebook computers, and other electronic  devices. Current passed through specific portions of the liquid crystal solu�  tion causes the crystals to align, blocking the passage of light. Doing so  in a controlled and organized manner produces visual images on the dis�  play screen. The advantage of LCDs is that they are much lighter and  consume less power than other display technologies (e.g., cathode-ray  tubes). These characteristics make them an ideal choice for flat-panel dis�  plays, as in portable laptop and notebook computers.</p><p>liquidity preference In economics, the premium that holders of  wealth demand for exchanging ready money or bank deposits for safe,  nonliquid assets such as government bonds.

Aug. 6, 1789, Reutlingen, Wiirttemberg,  Ger.�d. Nov. 30, 1846, Kufstein, Austria) German-born U.S. economist.  He first gained prominence as the founder of an association of German  industrialists that favoured abolishing tariff barriers between the German  states. Exiled in 1825 for his liberal views, he went to the U.S. In his Out�  lines of American Political Economy (1827) he maintained that a national  economy in an early stage of industrialization required tariff protection to  stimulate development. After becoming a U.S. citizen, he returned to Ger�  many as U.S. consul at Baden (1831�34) and Leipzig (1834-37). His best-  known work was The National System of Political Economy (1841).  Financial and other difficulties eventually drove him to suicide.</p><p>Lister, Joseph later Baron Lister (of Lyme Regis) (b. April 5,  1827, Upton, Essex, Eng.�d.

He received a medical degree from Oxford in  1852 and became an assistant to James Syme, the greatest surgical teacher  of the day. In 1861 he was appointed surgeon to the Glasgow Royal Infir�  mary, where he observed that 45-50% of amputation patients died from  sepsis (infection). Initially he theorized that airborne dust might cause  sepsis, but in 1865 he learned of Louis Pasteur�s theory that microorgan�  isms cause infection.

July 31, 1886,</p><p>Bayreuth, Ger.) Hungarian composer  and pianist. Encouraged by his  father, who was a talented amateur  musician, Liszt developed an early  interest in music and began compos�  ing at age eight. He studied piano  with Karl Czerny and composition  with Antonio Salieri in Vienna, mak�  ing his debut there in 1822. After a  Paris success in 1823, he toured  Europe, but his father�s early death  (1828) and a disastrous love affair  led to a desire to give up music for  the priesthood. Hearing violinist Nic-  colo Paganini perform in 1831, Liszt  was inspired to develop his own  technique to the utmost and to com�  pose his first mature pieces, includ�  ing the Transcendental Etudes (1837) and Paganini Etudes (1839). An  affair with Countess Marie d�Agoult resulted in the birth of his daughter,  Cosima (1837-1930), who would marry his friend, the composer Richard  Wagner. Liszt�s brilliance and success were at their peak during the  1840s, when he toured Europe as a virtuoso, earning great adulation for  his panache and his astounding technique. He ceased concertizing in the  late 1840s to devote himself to composition and furthering the work of  progressive composers. In the 1850s he wrote many of his most ambi�  tious works, including A Faust Symphony (1854) and the Piano Sonata  in B Minor ( 1853). In 1865 he took minor Roman Catholic church orders,  though he never became a priest. His later output is remarkable in antici�  pating many 20th-century developments; for instance, his development of  chromatic harmony influenced atonal music.</p><p>Litani \li-'ta-ne\ River River, southern Lebanon.

In ancient civilizations such as those of the Sumerians and  Babylonians, literacy was the province of an elite group of scholars and  priests. Though more prevalent in classical Greece and Rome, it was often  limited to members of the upper classes. The spread of literacy in Europe  in the Middle Ages was evidenced by the use of writing for functions  once conducted orally, such as the indenture of servants and the notation  of evidence at trials. The rise of literacy in Europe was closely tied to  great social transformations, notably the Protestant Reformation, which  brought individual study of the Bible, and the development of modern  science. The spread of literacy during the Reformation and the Renais�  sance was greatly facilitated by the development of printing from movable  type and by the adoption of vernacular languages in place of Latin. Com�  pulsory schooling, established in Britain, Europe, and the U.S. in the 19th  century, has led to high rates of literacy in the modern industrialized  world.</p><p>literary criticism Discipline concerned with philosophical, descrip�  tive, and evaluative inquiries about literature, including what literature is,  what it does, and what it is worth. The Western critical tradition began  with Plato�s Republic (4th century bc). A generation later, Aristotle, in his  Poetics, developed a set of principles of composition that had a lasting  influence. European criticism since the Renaissance has primarily focused  on the moral worth of literature and the nature of its relationship to real�  ity. At the end of the 16th century, Sir Philip Sidney argued that it is the  special property of literature to offer an imagined world that is in some  respects superior to the real one. A century later John Dryden proposed  the less idealistic view that literature must primarily offer an accurate rep�  resentation of the world for �the delight and instruction of mankind,� an  assumption that underlies the great critical works of Alexander Pope and  Samuel Johnson. A departure from these ideas appeared in the criticism  of the Romantic period, epitomized by William Wordsworth�s assertion  that the object of poetry is �truth...carried alive into the heart by pas�  sion.� The later 19th century saw two divergent developments: an aes�  thetic theory of �art for art�s sake,� and the view (expressed by Matthew  Arnold) that literature must assume the moral and philosophical functions  previously filled by religion. The volume of literary criticism increased  greatly in the 20th century, and its later years saw a radical reappraisal of  traditional critical modes and the development of a multiplicity of criti�  cal factions (see deconstruction; poststructuralism; structuralism).</p><p>literati Scholars in China and Japan whose poetry, calligraphy, and  paintings were supposed primarily to reveal their cultivation and express  their personal feelings rather than demonstrate professional skill. The  concept of literati painters was first formulated in China in the Northern  Song dynasty but was enduringly codified in the Ming dynasty by Dong  Qichang. In the 18th�19th century, literati painting became popular with  the Japanese, who exaggerated elements of Chinese composition and  brushwork.

Cementation is one of the main processes involved, par�  ticularly for sandstones and conglomerates. In addition, reactions take  place within a sediment between various minerals and between minerals  and the fluids trapped in the pores; these reactions may form new min�  erals or add to others already present in the sediment.</p><p>lithium Chemical element, lightest alkali metal, chemical symbol Li,  atomic number 3. It is soft, white, lustrous, and very reactive, forming  compounds in which it has valence 1. The metal is used in certain alloys,  as a coolant in nuclear reactors, and (because of its reactivity) as a reagent,  scavenger, and rocket fuel. Lithium hydride is used as a source of hydro�  gen; lithium hydroxide is used as an additive in storage batteries and to  absorb carbon dioxide. Halides (see halogen) of lithium are used as mois�  ture absorbents, and lithium soaps are used as thickeners in lubricating  greases. Lithium carbonate is an important drug for treating depression and  BIPOLAR DISORDER.</p><p>litho-offset See offset printing</p><p>lithography \li-'tha-gr3-fe\ Printing process that makes use of the  immiscibility of grease and water. Aloys Senefelder of Prague (1771�  1834) exploited the properties of a stone with a calcium carbonate base  and a fine, porous surface, and perfected his printing process in 1798. In  Senefelder�s process, the stone, with a design drawn on it with crayon or  greasy ink, was wetted with water; after various etching and protecting  steps, it was brushed with oily ink; it retained the ink only on the design.</p><p>This inked surface was then printed�either directly on paper, by a spe�  cial press (as in most fine-art printmaking), or onto a rubber cylinder and  thence onto paper (as in commercial printing). The method of preparing  stones for hand printing, still the lithographic method preferred by artists,  has hardly changed. Commercial lithographic printing on a modern rotary  OFFSET printing press can produce high-quality, finely detailed impressions  at high speed, reproducing any material that can be photographed in the  platemaking process. It now accounts for more than 40% of all printing,  packaging, and publishing, more than twice the percentage produced by  any other single printing process.</p><p>lithosphere Rigid, rocky outer layer of the Earth, consisting of the crust  and the solid outermost layer of the upper mantle. It extends to a depth of  about 60 mi (100 km). It is broken into about a dozen separate, rigid  blocks, or plates (see plate tectonics). Slow convection currents deep  within the mantle, generated by radioactive heating of the interior, are  believed to cause the lateral movements of the plates (and the continents  that rest on top of them) at a rate of several inches per year.</p><p>Lithuania officially Republic of Lithuania Country, northeastern  Europe.

Lan�  guages: Lithuanian (official), Russian, Pol�  ish, Belarusian. Religion: Christianity  (predominantly Roman Catholic; also  Eastern Orthodox). Currency: litas. The country consists of low-lying  plains alternating with hilly uplands, watered by rivers that meander west�  ward to the Baltic Sea. Manufacturing, including metalworking, wood�  working, and textile production, is especially important in the east and  south. Agriculture focuses on livestock breeding, especially dairy farm�  ing and pigs, and the cultivation of cereals, flax, sugar beets, potatoes,  and fodder crops. Lithuania is a multiparty republic with one legislative  house; its head of state is the president, and the head of government is  the prime minister. Lithuanian tribes united in the mid-13th century to  oppose the Teutonic Knights. Gediminas, one of the grand dukes, expanded  Lithuania into an empire that dominated much of eastern Europe in the  14th�16th centuries. In 1386 the Lithuanian grand duke became the king  of Poland, and the two countries remained closely associated for the next  400 years. Lithuania was acquired by Russia in the Third Partition of  Poland in 1795 and joined in the Polish revolt in 1863. Occupied by Ger�  many during World War I, it declared its independence in 1918. In 1940  the Soviet Red Army gained control of Lithuania, which was soon incor�  porated into the Soviet Union. Germany occupied Lithuania again from  1941, but the Red Army regained control in 1944.

Lithuanian is sparsely  attested until 1547, when the first book in the language was printed. Efforts  to develop a standard language in the late 19th century were dominated by  speakers of the West High dialect spoken in German-ruled East Prussia.  Among them was Jonas Jablonskis (1860-1930), whose orthography  (based on the Latin alphabet with numerous diacritics) and grammar (1901)  won official acceptance when Lithuania became independent. Lithuanian is  renowned for its archaism among living Indo-European languages.</p><p>litmus \Tit-mos\ Mixture of coloured organic compounds obtained from  several species of lichens. In the form of a water solution or as litmus  paper, it is the oldest and most-used indicator of whether a substance is  an acid or a base. It turns red or pink in acid solutions and blue or purple-  blue in alkaline solutions.</p><p>Little Armenia or Lesser Armenia Ancient kingdom, southeastern  coast of Anatolia. After initial struggles with the Byzantine Empire, it was  established in Cilicia by the Armenian Rubenid dynasty in the 12th cen�  tury and developed contacts with the West. It was influenced by cultural  contacts with Crusaders and with Venetian and Genoese merchants. It was  conquered by the Muslim Mamluk dynasty in 1375.</p><p>Little Bighorn, Battle of the or Custer's Last Stand (June 25,  1876) Battle at the Little Bighorn River, Montana Territory, U.S., between  federal troops led by Lt. Col. George Armstrong Custer and a band of  Sioux and Cheyenne Indians. The U.S. government had ordered the north�  ern Plains tribes to return to designated reservations and had sent troops  under Gen. Alfred H. Terry to enforce the order. Terry hoped to surround  an Indian encampment at the mouth of the Little Bighorn, but a party of  some 200 soldiers led by Custer launched an early attack and was slaugh�  tered. Government troops subsequently flooded into the area and forced  the Indians to surrender.</p><p>Little Entente \an-'tant\ Mutual defense arrangement formed in  1920-21 between Czechoslovakia, Yugoslavia, and Romania, with French  support. It was directed against German and Hungarian domination in the  Danube River basin and toward protection of its members� territorial  integrity. It was successful in the 1920s, but after Adolf Hitler�s rise to  power (1933) its members adopted increasingly independent foreign poli�  cies. The entente collapsed after Germany annexed the Czech Sudeten-  land (1938).</p><p>Little League International baseball organization for children and  youth, started in 1939 in Williamsport, Pa., by Carl E. Stotz and brothers  Bert and George Bebble. The league originally included boys aged 8-12;  girls were admitted in 1974. It now includes two upper divisions for  youths aged 13-15 and 16-18. In the junior division the game is played  on a field two-thirds the size of a professional baseball diamond. A sea�  son comprises about 15 games. The organization expanded rapidly after  World War II; by the 1990s there were about 2.5 million players in some  30 countries. The Little League World Series is held in Williamsport each  year in August.</p><p>little magazine Any of various small, usually avant-garde periodicals  devoted to serious literary writings. The name signifies most of all a usu�  ally noncommercial manner of editing, managing, and financing. They  were published from c. 1880 through much of the 20th century and flour�  ished in the U.S. and England, though French and German writers also  benefited from them. Foremost among them were two U.S. periodicals,  Poetry and the more erratic and often more sensational Little Review  (1914-29); the English Egoist (1914-19) and Blast (1914-15); and the  French transition (1927-38).</p><p>Little Missouri River River, northwestern U.S. It rises in northeast�  ern Wyoming and flows northeast across the southeastern comer of Mon�  tana and the northwestern comer of South Dakota. It continues north into  North Dakota, turning east to empty into the Missouri River after a course  of 560 mi (900 km). The Theodore Roosevelt National Park lies along its  shores in North Dakota.</p><p>Little Richard orig. Richard Wayne Penniman (b. Dec. 5, 1932,  Macon, Ga., U.S.) U.S. rhythm and blues singer and pianist. Born into a</p><p>strict religious family, he sang and played piano in church but was later  ejected from his home by his father, reportedly for homosexual behav�  iour. He performed in nightclubs, traveled with a medicine show, and  recorded as a blues artist from the early 1950s. His first big hit came with  �Tutti Frutti� (1956), an energetic performance that, with his penchant for  the outrageous, set a standard for the emerging rock idiom. Similar hits  followed, including �Long Tall Sally,� �Lucille,� and �Good Golly, Miss  Molly.� In 1957 he underwent a religious conversion and was later  ordained a minister. He soon returned to music, becoming a regular attrac�  tion in Las Vegas, and he continued to tour and appeal - in films with much  success. He was an original inductee into the Rock and Roll Hall of Fame.</p><p>Little Rock City (pop., 2000: 183,133), capital of Arkansas, U.S.,  located on the Arkansas River. In 1722 Bernard de la Harpe, a French  explorer, named the site La Petite Roche for a rock formation on the  riverbank. It became the capital of Arkansas in 1821. It was strongly anti-  Union at the outbreak of the American Civil War; Federal troops occupied  the city in 1863. It grew as the commercial centre of a farming region and  as a hub of railway and river transportation. In 1957 federal troops were  sent there to prevent state authorities from interfering with desegregation  at Central High School. The state�s largest city, it has many institutions  of higher learning, including the University of Arkansas at Little Rock</p><p>(1927).</p><p>Little St. Bernard Pass Mountain pass, Savoy Alps. Situated south�  west of the Italian border in southeastern France, it connects Bourg-St.-  Maurice, France, with La Thuile, Italy. Hannibal probably led the  Carthaginian army over the pass on his way toward Rome in 218 bc. It  was the principal route across the Alps into Gallia Comata, a province of  Gaul, until Montgenevre Pass was opened in 77 bc. Beside the pass is a  hospice founded in the 11th century by St. Bernard of Menthon.</p><p>little theatre Movement in U.S. theatre to free dramatic forms and  methods of production from the limitations of the large commercial the�  atres by establishing small experimental centres of drama. Young drama�  tists, stage designers, and actors influenced by the vital European theatre  of the late 19th century, especially by the theories of Max Reinhardt, estab�  lished community playhouses such as the Little Theatre, New York City  (1912), the Little Theatre, Chicago (1912), and the Toy Theatre, Boston  (1912). A few became important commercial producers; the Washington  Square Players (1915), for example, later became the Theatre Guild  (1918). Playwrights such as Eugene O'Neill, George S. Kaufman, and Max�  well Anderson found their early opportunities in the little theatres.</p><p>Little Turtle (b. c. 1752, near Fort Wayne, Ind.�d. July 14, 1812, Fort  Wayne, Ind., U.S.) American Indian leader. Chief of the Miami tribe, he  led raids on settlements in the Northwest Territory in the early 1790s.  Defeated by Gen. Anthony Wayne at the Battle of Fallen Timbers (1794),  he was obliged to sign the Treaty of Greenville (1795), which ceded to  the U.S. much of Ohio and parts of Illinois, Indiana, and Michigan. He  then advocated peace and prevented the Miami from joining the Shaw�  nee confederacy of Tecumseh.</p><p>Littleton, Sir Thomas (b. 1422, probably at Frankley, Worcestershire,  Eng.�d. Aug. 23, 1481, Frankley) British jurist. In a turbulent period he  held several high offices, including judge of the Court of Common Pleas  (from 1466). His Littleton on Tenures (1481 or 1482) was the earliest  treatise on English law ever printed. It long remained the principal author�  ity on English real property law.</p><p>liturgical drama Play acted in or near the church in the Middle Ages.  The form probably dated from the 10th century, when the �Quern quaeri-  tis� (�Whom do you seek�) section of the Easter mass was performed as  a small scene in the service. The plays gradually increased in length, with  themes derived from biblical stories (particularly those of Easter and  Christmas), and they flourished in the 12th�13th centuries. Their Latin  dialogue was frequently chanted to simple melodies. They continued to  be written into the 16th century, but the connection with the church even�  tually ended as the plays came under secular sponsorship and were acted  in the vernacular. See also miracle play; morality play; mystery play.</p><p>Liturgical movement 19th- and 20th-century effort to encourage the  active participation of the laity in the liturgy of the Christian churches by  creating simpler rites more attuned to early Christian traditions and more  relevant to modern life.

Meir  Walach (b. July 17, 1876, Bialystok, Pol.�d. Dec. 31, 1951, Moscow,  Russia, U.S.S.R.) Soviet diplomat and commissar of foreign affairs  (1930-39). He joined the Russian Social-Democratic Workers' Party  (1898), was arrested for revolutionary activity (1901), and fled to Britain.  In 1917-18 he represented the Soviet government in London, then  returned to Russia, where he joined the Commissariat for Foreign Affairs  and led Soviet delegations to disarmament conferences. As commissar for  foreign affairs, he established diplomatic relations with the U.S. (1934),  negotiated anti-German treaties with France and Czechoslovakia (1935),  and urged the League of Nations to resist Germany (1934-38). He was  dismissed before the signing of the German-Soviet Nonaggression Pact  (1939). He served as ambassador to the U.S. (1941-43).</p><p>Liu Bang See Gaozu</p><p>Liu Shaoqi Ue-'ii-'shau-'cheN or Liu Shao-ch'i (b. Nov. 24, 1898,  Ningxiang district, Hunan province, China�d.

An activist  communist background from the 1920s helped Liu�s rise within the CCP  in the 1930s and �40s, while his excellent education and studies in the  Soviet Union made him an effective spokesman for the new government  in China. When Mao resigned as chairman after the failure of his Great  Leap Forward, Liu assumed the title. His policies for revitalizing agricul�  ture by permitting peasants to cultivate private plots and giving them  monetary incentives were ones to which Mao later strongly objected. In</p><p>1968 Liu was purged from power for being a �capitalist roader� and Lin  Biao was appointed Mao�s successor. Not until 1974 was Liu�s death in</p><p>1969 made public.</p><p>Liu Songnian or Liu Sung-nien (b. 1174�d. 1224, Qiantang, Zhe�  jiang province, China) Chinese figure and landscape painter. Liu entered  the Southern Song Painting Academy as a student in the Chunxi period  (1174-89) and went on to become a daizhao (�painter-in-attendance�) in  the Shaoxi period (1190-94). During the reign of the emperor Ningzong  (1195-1224) he was awarded the prestigious Golden Belt. Liu followed  the tradition of Li Tang. Typically his works featured relatively large fig�  ures executed in a detailed manner and placed close to the spectator in  the picture plane. The facial expressions of his figures are vivid, and the  patterns in which their clothing drapes are very intricate. His most impor�  tant landscape paintings depict a human in harmony with nature. Liu  paved the way for an academic style that would be further developed by  his contemporaries Ma Yuan and Xia Gui.</p><p>live oak Any of several North American ornamental and timber trees  in the red-oak group of the genus Quercus in the beech family. The south�  ern live oak ( Q. virginiana ) is a massive (50 ft, or 15 m, tall), durable  evergreen tree. The trunk divides near the ground into several limbs that  extend horizontally as much as two to three times the height of the tree.  The elliptical leaves are dark green and glossy above, whitish and hairy  below. A valuable timber tree, the southern live oak is also planted as a  shade and avenue tree in the southern U.S. The oldest trees are 200-300  years old.</p><p>liver Largest gland in the body, with several lobes. It secretes bile;  metabolizes proteins, carbohydrates, and fats; stores glycogen, vitamins, and  other substances; synthesizes coagulation factors; removes wastes and  toxic matter from the blood; regulates blood volume; and destroys old red  blood cells. The portal vein carries blood from the gastrointestinal tract,  gallbladder, pancreas, and spleen to the liver to be processed. A duct sys�  tem carries bile from the liver to the duodenum and the gallbladder. Liver  tissue consists of a mass of cells tunneled with bile ducts and blood ves�  sels. About 60% are hepatic cells, which have more metabolic functions  than any other cells. A second type, Kupffer cells, play a role in blood�  cell formation, antibody production, and ingestion of foreign particles and  cell debris. The liver manufactures plasma proteins, including albumin and  clotting factors, and synthesizes enzymes that modify substances such as  nutrients and toxins, filtered from the blood.

It forms the nucleus of the metropolitan county of  Merseyside in the historic county of Lancashire. King John granted its char�  ter in 1207. Its growth was slow until the 18th century, when it expanded  rapidly as a result of trade with the Americas and the West Indies, becoming  Britain�s most important port after London. The Liverpool and Manchester  Railway (opened 1830) was the first in England to link two major cities.  Heavily damaged in World War II, it declined in importance as a port and  an industrial centre in the postwar era. The birthplace of the Beatles, it is  also the seat of the University of Liverpool (1903).</p><p>Liverpool, Robert Banks Jenkinson, 2nd earl of (b. June 7,  1770, London, Eng.�d. Dec. 4, 1828, Fife House, Whitehall, London)  British prime minister (1812-27). He entered the House of Commons in  1790 and became a leading Tory, serving as foreign secretary (1801-04),  home secretary (1804-06, 1807-09), and secretary for war and the colo�  nies (1809-12). The War of 1812 with the U.S. and the final campaigns  of the Napoleonic Wars were fought during his premiership. He urged  abolition of the slave trade at the Congress of Vienna (1814-15). Although  sometimes overshadowed by his colleagues and by the duke of Welling�  ton�s military prowess, he conducted a sound administration.</p><p>liverwort Any of more than 8,000 species of small, nonvascular, spore-  producing land plants that make up the class Hepatopsida (or Hepaticae)  of bryophytes, found worldwide but mostly in the tropics. Thallose liver�  worts commonly grow on moist soil or damp rocks; leafy liverworts are  found in similar habitats and on tree trunks in damp woods. Sexual (game-  tophyte) and asexual (sporophyte) generations alternate in the life cycle (see  alternation of generations). The thallus of thallose liverworts, resembling  a lobed liver, gives liverworts their name. Though not economically  important to humans, liverworts provide food for animals, facilitate the  decay of logs, and aid in the disintegration of rocks by their ability to  retain moisture.</p><p>livestock Farm animals, with the exception of poultry. In Western coun�  tries the category encompasses primarily cattle, sheep, pigs, goats, horses,  donkeys, and mules; other animals (e.g., buffalo, oxen, or camels) may pre�  dominate in other areas.

It was  formed in New York City in 1947 by Julian Beck (1925-85) and Judith  Malina (b. 1926) to produce experimental plays, often on radical themes.  Its first big success was Jack Gelber�s The Connection (1959), a drama  of drug addiction. After problems with U.S. tax authorities, the company  was relocated to Europe (1964-68). It returned to New York City to  present the confrontational Paradise Now (1968), a production intended  to spark revolution. In the 1970s the group presented a cycle of plays in  public spaces and nontraditional venues (Pittsburgh steel mills, Brazilian  prisons, the streets of Palermo, Italy) under the collective title The Legacy  of Cain. Thereafter the company performed again in theatres, continuing  to examine new dramatic techniques. After 1999 The Living Theatre  divided its time between headquarters in Italy and New York City.</p><p>living will Document specifying  medical measures to be taken or  withheld in the event the writer is  disabled. Advances in medical tech�  nology now allow the body to be  kept alive in circumstances that  would normally result in death (e.g.,  inability to eat, breathe, or maintain  the heartbeat), but many people do  not want to be kept alive if there is  no chance of recovery. Because it is  impossible to express one�s wishes  when in a vegetative state, a living  will allows them to be stated in  advance. Such a document usually  specifies conditions under which a  do-not-resuscitate (DNR) order is to  take effect and authorizes another  person to make decisions on the  patient�s behalf.</p><p>Livingston, Robert R.

George Wash�  ington (1789). From 1781 to 1783 he was U.S. secretary of foreign affairs.  As minister to France from 1801 to 1804, he helped effect the Louisiana  Purchase. In partnership with Robert Fulton, he later received a steamboat  monopoly for New York waters; the first vessel to operate on the Hudson  River (1807) was named the Clermont, after his ancestral home.</p><p>Livingston, William (b. Nov. 30, 1723, Albany, N.Y.�d. July 25,  1790, Elizabeth, N.J.) American politician. He served in the New York  legislature (1759-60), wrote political pamphlets and newspaper articles,  and helped prepare a digest of New York laws for the period 1691 to 1756.  He moved to New Jersey in 1772 and represented the colony in the Con�  tinental Congress (1774-76). As New Jersey�s first governor (1776-90),  he was a delegate to the Constitutional Convention and led his state to an  early ratification of the U.S. Constitution.</p><p>Livingstone, David (b.

Of working-class origins,</p><p>Livingstone studied theology and  medicine in Glasgow before being  ordained (1840) and deciding to  work in Africa to open up the inte�  rior for colonization, extend the Gos�  pel, and abolish the slave trade. By  1842 he had already penetrated far�  ther north of the Cape Colony fron�  tier than any other white man. He  was the first European to reach Lake  Ngami (1849) and the first to reach  Luanda from the interior (1854). He  encountered and named Victoria Falls  (1855), journeyed across the conti�  nent to eastern Mozambique (1856,</p><p>1862), explored the Lake Malawi  region (1861-63), came across  Lakes Mweru and Bangweulu (1867),  and penetrated to points farther east  of Lake Tanganyika than any previ�  ous expedition had managed (1871). His attempt to find the source of the  Nile (1867-71) failed. When he was found by Henry Morton Stanley in  1871, his health was failing; he refused to leave, and in 1873 he was found  dead by African aides. Livingstone produced a complex body of  knowledge�geographic, technical, medical, and social�that took  decades to mine. In his lifetime he stirred the imagination of English-  speaking peoples everywhere and was celebrated as one of the great fig�  ures of British civilization.</p><p>Livonia Region, eastern coast of Baltic Sea, north of Lithuania. Origi�  nally inhabited by the Livs, a Finno-Ugric people, it eventually expanded  to include nearly all of modem Latvia and Estonia. In the 13th century it  was conquered and Christianized by the Order of the Brothers of the  Sword and organized into the Livonian confederation. A Russian invasion  set off the Livonian War (1558-82), in which Russia, Poland, and Swe�  den seized portions of it. Sweden eventually gained control of most of it  but ceded the region to Russia in 1721. In 1918 the northern portion  became part of independent Estonia and the southern portion joined inde�  pendent Latvia.</p><p>Livorno English Leghorn City (pop., 2001 prelim.: 148,143), Tuscany  region, central Italy, on the Ligurian Sea. Originally a fishing village, it  came under Florentine rule in 1421. Cosimo I began construction of the  Medici Harbour in the 16th century, and under Ferdinand I of Tuscany  (1549-1609) the city became a haven for refugees. In the 18th century  Leopold II enlarged the harbour and gave privileges to foreign merchants.  Livorno became part of the Kingdom of Italy in 1860. One of Italy�s larg�  est ports, it has extensive commercial activities and a large shipbuilding  yard. Historic sites include a cathedral and a 16th-century fort.</p><p>Livy \Ti-ve\ orig. Titus Livius (b. 59/64 bc, Patavium, Venetia�d. ad  17, Patavium) Roman historian. Little is known of his life, most of which  must have been spent in Rome. His lifework was a history of the city,  written in 142 books; Books 11-20 and 46-142 have been lost, and those</p><p>after Book 45 are known only from fragments and later summaries. Unlike  earlier Roman historians, Livy played no part in politics, and as a result  he presented history not as partisan politics but in terms of character and  morality. The Latin prose style he developed suited his subject matter. His  history, a classic in his lifetime, profoundly influenced the style and phi�  losophy of historical writing down to the 18th century.</p><p>lizard Any of about 3,000 species of reptiles constituting the suborder  Sauria. They are most diverse and abundant in the tropics but are found  from the Arctic Circle (one species) to southern Africa, South America,  and Australia. Like snakes, lizards have scales, paired male copulatory  organs, and a flexible skull. Typical lizards have a moderately cylindrical  body, four well-developed legs (although some lizards are legless), a tail  slightly longer than the head and body combined, and movable lower  eyelids. They range in size from 1-in. (3-cm) geckos to the 10-ft (3-m)  Komodo dragon, but most are about 12 in. (30 cm) long. Ornamentation  includes crests on the head, back, or tail; spines; brightly coloured throat  fans; and throat frills. Most species feed on insects and rodents, but some,  such as the iguana, eat plants. See also Gila monster; horned toad.</p><p>Ljubljana Me-.u-ble-'a-noV City (pop., 2002 prelim.: 257,338), capital of  Slovenia. Located on the Ljubljanica River, it is surrounded by the north�  ern Dinaric Alps. The site of the Roman city of Emona in the 1st century  bc, it was destroyed in the 5th century ad and rebuilt by the Slavs as Luvi-  gana. It passed to Carniola in the 12th century and came under Habsburg  rule in 1277. Taken by the French in 1809, it was the administrative seat  of the Illyrian Provinces until 1813 and the capital of the kingdom of Illyria  from 1816 to 1849. It was the centre of Slovene nationalism under Aus�  trian rule, and in 1918 it became part of the Kingdom of Serbs, Croats,  and Slovenes (later Yugoslavia). It remained the Slovene capital after Slo�  venia�s independence in 1992. A railroad and commercial centre, it is the  site of the University of Ljubljana (founded 1595).</p><p>llama \'la-mo\ Domesticated South American lamoid (see alpaca), main�  tained in herds in Bolivia, Peru, Ecuador, Chile, and Argentina. The llama  {Lama glama) is used primarily as a pack animal but also as a source of  food, wool, hides, tallow for candles, and dried dung for fuel. A 250-lb  (113-kg) llama can carry a load of 100-130 lb (45-60 kg) and travel 15-20  mi (25-30 km) a day. It can subsist on little water and a wide variety of  plant materials. Though usually white, it may be solid black or brown, or  white with black or brown markings. It is usually gentle, but when over�  loaded or mistreated it will lie down, hiss, spit and kick, and refuse to  move. Not known to exist in the wild state, it appears to have been bred  from guanacos during or before the Inca civilization.</p><p>Llandrindod Uilan-'drin-.dadX Wells Town (pop., 1991: 4,362),  administrative centre of Powys county, historic county of Radnorshire,  eastern Wales. Its medicinal waters were first discovered c. 1696, and in  the 19th century it became a popular spa. The spa declined after World  War II and closed in the 1960s but reopened in 1983. To the northwest  lie the remains of a Roman fort.</p><p>Llano Estacado Vla-no-.es-to-'ka-doX or Staked Plain Plateau,  southeastern New Mexico and western Texas, U.S. Occupying an area of  about 30,000 sq mi (78,000 sq km), it is a semiarid plain with occasional  pools of rainwater. Its soil supports grazing, dryland farming of grains,  and irrigated cotton production. Production of petroleum and natural gas  is also important. Lubbock and Amarillo, Texas, are its most important cit�  ies.</p><p>Llanquihue \laq-'ke-w9. Lake Lake, south-central Chile.

March 26, 1945, Ty-newydd, near  Llanystumdwy, Caernarvonshire, Wales) British prime minister (1916�  22). He entered Parliament in 1890 as a Liberal and retained his seat for  55 years. He served as president of the Board of Trade (1905-08), then  as chancellor of the Exchequer (1908-15). Rejection of his controversial  �People�s Budget� (to raise taxes for social programs) in 1909 by the  House of Lords led to a constitutional crisis and passage of the Parliament  Act of 1911. He devised the National Insurance Act of 1911, which laid  the foundation of the British welfare state. As minister of munitions (1915-  lb), he used unorthodox methods to ensure that war supplies were forth�  coming during World War I. He replaced H.H. Asquith as prime minister  in 1916, with Conservative support in his coalition government. His small  war cabinet ensured speedy decisions. Distrustful of the competence of  the British high command, he was constantly at odds with Gen. Douglas  Haig. In the 1918 elections his decision to continue a coalition govern�  ment further split the Liberal Party. He was one of the three great states�  men responsible for the Treaty of Versailles at the Paris Peace Conference.  He began the negotiations that culminated in the Anglo-Irish treaty of  1921. He resigned in 1922 and headed an ailing Liberal Party (1926-31).</p><p>Lloyd Webber, Andrew later Baron Lloyd Webber (b. March  22, 1948, London, Eng.) British composer. He studied at Oxford and at  the Royal College of Music. His first collaboration with lyricist Tim Rice  (b. 1944), Joseph and the Amazing Technicolor Dreamcoat (1968), was  followed by the �rock opera� Jesus Christ Superstar (1971), which  blended classical forms with rock music. Their last major collaboration  was Evita (1978). Lloyd Webber�s eclectic, rock-based works helped revi�  talize musical theatre. In both London and New York City, his musical  Cats (1981), based on poems by T.S. Eliot, became the longest-running  musical in history. He later collaborated on Starlight Express (1984),  Phantom of the Opera (1986), and Sunset Boulevard (1993), among other  stage works. He was knighted in 1992 and ennobled in 1996.</p><p>Lloyd's of London Insurance marketing association in London, spe�  cializing in high-risk insurance services. Its history dates to 1688, when  Edward Lloyd kept a London coffeehouse where merchants, seafarers, and  marine-insurance underwriters met to transact business. The underwriters  at Lloyd�s eventually formed a marine-insurance association (incorpo�  rated 1871); it expanded to include other forms of insurance in 1911. After  a series of financial scandals, the corporation was reorganized under the  Lloyd�s Act of 1982. Today Lloyd�s consists of more than 20,000 indi�  vidual members organized in several hundred syndicates, which are rep�  resented at Lloyd�s by underwriting agents. Individual syndicate  members, rather than the corporation, are liable for losses. Until record  losses in the 1980s and �90s bankrupted some syndicate members, they  had unlimited liability for business transacted for them; in 1993 that liabil�  ity was limited.

He was reared at die court of Majorca,  where he wrote lyrical troubadour poetry. He later traveled widely,  attempting to convert Muslims to Christianity; he is said to have been  stoned to death at Bejai'a. As a philosopher, he is best known as the inven�  tor of an �art of finding truth.� Primarily intended to support the church  in its missionary work, it was also designed to unify all branches of  knowledge. In his principal work, Ars magna (1305-08), he tried to depict  all forms of knowledge, including theology, philosophy, and the natural  sciences, as mutually analogous and manifestations of the godhead in the  universe. His writings influenced Neoplatonic mysticism throughout  medieval and early modern Europe. In Catalan culture, his allegorical  novels Blanquerna (c. 1284) and Felix (c. 1288) enjoy wide popularity;  he is also known for his treatise on chivalry, his animal fables, and an  encyclopaedia of medieval thought.</p><p>Llyr Vhlir\ In Celtic religion, the leader of one of the two warring fami�  lies of the gods. According to one interpretation, the Children of Llyr were  the powers of darkness, constantly in conflict with the Children of Don,  the powers of light. In Welsh tradition, Llyr and his son Manawydan were  associated with the sea. Llyr�s other children included Bran, Creidylad,  and Branwen, wife of the sun god Matholwch, king of Ireland.</p><p>Llywelyn ap Gruffudd Milo-'we-lin-ap-'gri-fithX (d. Dec. 11, 1282,  near Builth, Powys, Wales) Prince of Wales (1258-77). As prince of  Gwynedd in northern Wales from 1255, he sought to extend his rule  throughout his native country, and he proclaimed himself prince of Wales  in 1258. He fought the English lords of southern Wales (1262) and allied  himself with Henry Ill�s opponent, Simon de Montfort. After Montfort�s  death, however, he signed a treaty recognizing Henry as overlord (1267).  Llywelyn rebelled against Edward I but was defeated by him in 1277. He  was killed in a final rebellion in 1282, and Wales soon fell entirely under  English rule.</p><p>Llywelyn ap lorwerth Milo-'we-lin-ap-'yor-wertlA known as Lly-  welyn the Great (d. April 11, 1240, Aberconway, Gwynedd, Wales)  Welsh prince. The grandson of a powerful Welsh prince, he was exiled  as a child from Gwynedd in northern Wales but returned in 1194 and  deposed his uncle, gaining control of most of northern Wales by 1202.  Though Llywelyn married King John�s daughter, the English king invaded  Wales when Llywelyn�s authority reached too far (1211). Llywelyn soon  recovered his lands and allied with John�s baronial opponents. Henry III  acknowledged his rule in most of Wales (1218), but by 1223 Llywelyn  was forced to withdraw to the north.</p><p>Lo-lang See Nangnang</p><p>load-bearing wall See bearing wall</p><p>loam Rich, friable (crumbly) soil with nearly equal parts of sand and  silt, and somewhat less clay.

In 1829 he published his ground�  breaking theory, a geometry that rejected Euclid�s parallel postulate. It was  the final solution to a problem that had baffled mathematicians for 2,000  years. Lobachevsky also did distinguished work in the theory of infinite  series, especially trigonometric series, as well as in integral calculus, alge�  bra, and probability. He was largely ignored during his lifetime; acceptance  of his new geometry came a decade after his death, though much of the  credit went to others. With Bolyai Janos of Hungary (1802-60),  Lobachevsky is considered the founder of non-Euclidean geometry.</p><p>Lobamba Town (pop., 1995 est.: 10,000), legislative capital of Swazi�  land. Located near Mbabane, it is in a densely populated rural area. It is,  according to traditional Swazi customs, the residence of the Queen Mother  and is thereby the spiritual home of the Swazi nation. It is the site of par�  liamentary buildings and an official residence of the king.</p><p>lobbying Any attempt by a group or individual to influence the decisions  of government. The term originated in 19th-century efforts to influence the  votes of legislators, generally in the lobby outside a legislative chamber.  The effort may be a direct appeal to a decision maker in either the executive  or legislative branches, or it may be indirect (e.g., through attempts to influ�  ence public opinion). It may include oral or written efforts of persuasion,  campaign contributions, public-relations campaigns, research supplied to  legislative committees, and formal testimony before such committees. A  lobbyist may be a member of a special-interest group, a professional will�  ing to represent any group, or a private individual. In the U.S., the Lederal  Regulation of Lobbying Act (1946) requires that lobbyists and the groups  they represent register and report contributions and expenditures.</p><p>lobelia family Uo-'bel-yoX Lamily Lobeliaceae, which contains about  750 species of flowering plants in 25 genera. Some are grown for their  attractive, two-lipped flowers. Postlike and shaggy-tree forms are found  on mountains in Africa. The family includes the cardinal flower, great blue  lobelia (L. siphilitica), and Indian tobacco (L. inflata). Once used for  smoking and for the vomit-inducing alkaloid in its roots, lobelia is now  regarded as poisonous.</p><p>Lobengula V.lo-beq-'gyii-loV (b. c. 1836, Mosega, Transvaal�d.

Intro�  duced in 1935 by Antonio Egas Moniz and Almeida Lima, it came to be  used to help grossly disturbed patients. Favoured for patients who did not  respond to shock therapy, it did reduce agitation but often caused increased  apathy and passivity, inability to concentrate, and decreased emotional  response. It was widely performed until c. 1956, when drugs that were  more effective in calming patients became available. Lobotomies are no  longer performed; however, psychosurgery, the surgical removal of spe�  cific regions of the brain, is occasionally used to treat patients whose  symptoms have resisted all other treatments.</p><p>lobster Any of numerous species of marine shrimplike decapods that are  bottom-dwellers and mostly noctur�  nal. Lobsters scavenge for dead ani�  mals but also eat live fish, small  mollusks and other bottom-dwelling  invertebrates, and seaweed. One or  more pairs of legs are often modified  into pincers, usually larger on one  side than the other. True lobsters  have a distinct snout on the upper  body shell. The American lobster  (Homarus americanus) and SCAMPI  are the most commercially impor�  tant, being highly prized as food. The  American lobster, found from Labra�  dor to North Carolina, weighs about  1 lb (0.5 kg) and is about 10 in. (25  cm) long when caught in shallow water. Most deepwater specimens weigh  about 5.5 lbs (2.5 kg); some may weigh 40 lbs (20 kg).

Individual users can share data or files on a LAN as if the data  or files resided on their respective computers; a central computer used for  this purpose is called a server. Laser printers and other peripheral equip�  ment can be connected to a LAN for common use. Coaxial and fibre-optic  cables are popular communication lines for LANs because they provide  fast data transmission and are easy to install.

Nothing is</p><p>known of his early life, but he may have studied in The Netherlands before  settling in Cologne c. 1430, for Flemish influence is evident in his atten�  tion to minute details. Jan van Eyck�s influence is seen in The Adoration  of the Magi, his altarpiece for Cologne�s great cathedral, but Lochner adds  his own naturalistic observation and masterly sense of colour and design.  Known for his highly mystical religious paintings, he is considered the  greatest representative of the school of Cologne.</p><p>lock Mechanical or electronic device for securing a door or receptacle  so that it cannot be opened except by a key or a code. The lock originated  in the Middle East; the oldest known example was found near Nineveh.  Possibly 4,000 years old, it is of the pin tumbler type, otherwise known  as an Egyptian lock. The Romans were the first to use metal locks and to  make small keys for them. They also invented wards, projections in the  keyhole that prevent a key from turning unless it has slots that avoid the  projections. Probably the most familiar lock today is the cylinder lock, a  pin tumbler lock opened by a flat key with a serrated edge; the serrations  raise pins in the cylinder to the proper heights, allowing the cylinder to  turn. Also common are the unit lock, housed within a rectangular notch  cut into the edge of a door, and the mortise lock, housed in a mortise cut  into the door edge, the lock mechanism being covered on both sides. Other  types include lever and combination locks. Electronic locks that open with  a magnetic card key are popular for banks, hotel rooms, and offices.</p><p>A cylinder lock's tumbler consists of a series of pins arranged in pairs. The pins are  spring-loaded to press against the contours of the inserted key. A wrong key will  cause one or more of the pins to block the cylinder from turning; only when the tops  of all the lower pins line up with the edge of the cylinder can the cylinder turn.</p><p>� MERRIAM-WEBSTER INC.</p><p>Locke, John (b. Aug. 29, 1632, Wrington, Somerset, Eng.�d. Oct. 28,  1704, Oates, Essex) English philosopher. Educated at Oxford, principally  in medicine and science, he later became physician and adviser to the  future 3rd earl of Shaftesbury (1667-72). He moved to France, but after  Shaftesbury�s fall in 1683 he fled to the Netherlands, where he supported  the future William III. Locke returned to England after the Glorious Revo�  lution (1688) to become commissioner of appeals, a post he held until his  death. In his major philosophical work, Essay Concerning Human Under�  standing (1690), he argued that knowledge begins in sensation or intro�  spection rather than in innate ideas, as the philosophers of rationalism held.  From sensation and reflection the mind receives �ideas,� which are the  material of knowledge. Some ideas represent actual qualities of objects  (such as size, shape, or weight) and others perceived qualities, which do  not exist in objects except as they affect observers (such as colour, taste,  or smell); Locke called the former qualities �primary� and the latter �sec�  ondary.� Ideas that are given directly in sensation or reflection are simple,  and simple ideas may be �compounded� to form complex ideas. Locke  did not succeed in giving a clear account of the origin of the idea of sub�  stance (it is �a something-I-know-not-what�) or the idea of the �self,�  though his account of personal identity in terms of memory was influen�  tial.

U.S. diversified company that is one of the  world�s largest aerospace manufacturers. It was established in 1995  through the merger of Lockheed Corp. (formed 1926 as Lockheed Air�  craft Co.) and Martin Marietta Corp. (formed 1961 from the merger of  Martin Co. and American-Marietta Co.). During World War II, Lockheed  established a secret division (�Skunk Works�) that became the leading  U.S. developer of military aircraft (e.g., F-104 fighter, U-2 and SR-71 spy  planes, and F-117A stealth fighter). In the early 1970s its financially  troubled production of the L-1011 TriStar commercial jetliner necessitated  its rescue from bankruptcy by massive U.S. government aid. Lockheed�s  work in missile development resulted in the Polaris, Poseidon, and Trident  submarine-launched ballistic missile systems; in the space sector its  activities included the construction and systems integration of the Hubble  Space Telescope. In the early 1990s, in partnership with Boeing Co., it con�  tracted to build the F-22 Raptor stealth fighter (first flown 1997). Martin  Co.�s major business after World War II was the development of rockets  (e.g., Titan) and electronics systems for the U.S. government. Later, as  Martin Marietta, it constructed the Viking Mars landers and the Magellan  spacecraft to Venus and designed and produced the external fuel tank for  the space shuttle. In the mid-1990s Lockheed Martin formed a joint ven�  ture, International Launch Services, with the Russian firms Energia and  Khrunichev to market commercial space launch services.</p><p>lockjaw See tetanus</p><p>lockout Tactic used by employers in labour disputes, in which employ�  ees are locked out of the workplace or otherwise denied employment. In  the 1880s and �90s, factory owners in the U.S. often used lockouts against  the Knights of Labor, which was struggling to organize industries such as  meatpacking and cigar making. The lockout has been used less frequently  in modern times, usually as part of a pact among members of employers�  associations to frustrate labour unions by closing work facilities in  response to strikes.</p><p>Locofoco \,lo-ko-'fo-ko\ Party Radical wing of the Democratic Party  organized in New York City in 1835. Made up largely of workingmen and  reformers, the party opposed state banks, monopolies, tariffs, and special  interests. Its name derives from the friction matches, known as locofocos,  that radicals used to light candles when Democratic Party regulars tried  to oust them from a Tammany Hall meeting by turning out the gas lights.  Never a national party, the Locofocos reached the height of their influ�  ence when Congress passed the Independent Treasury Act (1840), which  effected the primary Locofoco aim of complete separation of government  and banking. The party was reabsorbed into the Democratic Party in the  1840s.</p><p>locomotion Any of various animal movements that result in progres�  sion from one place to another. Locomotion is classified as either appen�  dicular (accomplished by special appendages) or axial (achieved by  changing the body shape). Aquatic protozoans move by ciliary or flagel�  lar appendages or by pseudopods, footlike appendages. Other forms of  aquatic locomotion include walking on legs (some arthropods), crawling  (by contracting the body muscles, anchoring to the substrate, and extend�  ing), and swimming by either hydraulic propulsion (e.g., jellyfish) or undu�  lation (fishes). Terrestrial arthropods and vertebrates move by means of  jointed appendages, the legs. Snakes and other limbless vertebrates crawl  by means of muscular thrusts against the substrate. Flight is achieved by  the forward thrust of wings.</p><p>locomotive Self-propelled vehicle used for hauling railroad cars on  tracks. Early experimental steam locomotives were built in Wales and  England by Richard Trevithick from 1803. The first practical steam loco�  motive, the Rocket, was developed in 1829 by George Stephenson, in  whose �steam blast� system the steam from a multitube boiler drove pis�  tons connected to a pair of flanged driving wheels. The first U.S. steam  locomotive was built by John Stevens in 1825, and the first commercially  usable locomotive, the Tom Thumb, by Peter Cooper in Baltimore in 1830.  Later improvements enabled a locomotive to move up to 200 freight cars  at 75 mph (120 kph). Steam from wood or coal fuel was the main source</p><p>of power until the mid-20th century, though electric power had been used  from the early 20th century, especially in Europe. After World War II die�  sel power replaced steam because of its higher efficiency and lower cost,  though diesel-electric and gas turbine-electric combinations were also  used.</p><p>locoweed Any of several species of poisonous plants of the genera  Astragalus and Oxytropis, in the pea family (see legume), native to the  prairies of north-central and western North America. These low-growing  plants (up to 1.5 ft [45 cm] high) have variably hairy, fernlike leaves and  spikes of pealike flowers. They pose a danger to grazing animals because  they contain a toxin that affects muscle control, producing frenzied behav�  iour, impaired vision, and sometimes death. Because they taste bad, live�  stock usually eat them only when other forage is scarce. Decaying  locoweeds release toxins into the soil that are sometimes absorbed by  otherwise harmless forage crops.</p><p>Locri Epizephyrii \ , lo- l kri- l e-pi-z9- , fir-e- l i\ Ancient city in Magna  Graecia, on the eastern coast of Italy�s southwestern extremity. Founded  by Greeks c. 680 bc, it was the first Greek community to have a written  code of laws, the Locrian code (c. 660 bc). It founded colonies and resisted  Athenian intervention during the Peloponnesian War. Fickle in its alle�  giance, it was captured by Rome in 205 bc and destroyed by Sicilian  Muslims in 915.</p><p>locust In botany, any of about 20 tree species in the genus Robinia of  the pea family (see legume), all native  to eastern North America and  Mexico. Best-known is the black  locust (R. pseudoacacia ), often  called false acacia or yellow locust.</p><p>Widely cultivated in Europe as an  ornamental, it grows 80 ft (24 m)  high and bears long, compound  leaves. The fragrant white flowers  hang in loose clusters. There are  many varieties, some thornless. The  black locust has long been used for  erosion control and as a timber tree.</p><p>The so-called honey locust ( Gledit -  sia triacanthos), also of the pea family, is a North American tree com�  monly used as an ornamental and often found in hedges.</p><p>locust Any of several species of grasshoppers (family Acrididae) that  undergo population explosions and migrate long distances in destructive  swarms. In North America the names locust and grasshopper are inter-  changable and used for any acridid; cicadas are sometimes called locusts.  In Europe, locust refers to large species and grasshopper to small ones.  Locusts are found worldwide. Sporadic locust swarms may be explained  by the theory that swarming species have a solitary phase (the normal  state) and a gregarious phase. Nymphs that mature in the presence of many  other locusts develop into the gregarious type; thus migratory swarms  form as a result of overcrowding. Swarms may be almost unimaginably  large, towering 5,000 ft (1,500 m) high; in 1889 a Red Sea swarm was  estimated to cover 2,000 sq mi (5,000 sq km). Locust plagues can be  extremely destructive of crops.</p><p>lodestone See magnetite</p><p>lodge Originally an insubstantial dwelling, or one erected for a tempo�  rary occupational purpose (e.g., woodcutting or masonry) or for use dur�  ing the hunting season. The lodge became a more permanent type of house  as the lands around European mansions were developed as parks. The  lodge was often the cottage of the gamekeeper, caretaker, gatekeeper, or  gardener, or it could be a larger building for occupation by a higher�  ranking person. Today the word suggests a rustic dwelling or inn in a  natural setting, often one used seasonally (e.g., a ski lodge).</p><p>Lodge, Henry Cabot (b. May 12,1850, Boston, Mass., U.S.�d.

In 1960 he was the  Republican vice presidential candidate under Richard Nixon. During the  1960s he served as U.S. ambassador to South Vietnam and as ambassa�  dor to West Germany. In 1969 he was the chief U.S. negotiator at the  Paris peace talks with North Vietnam. He later served as special envoy  to the Vatican.</p><p>Lodi \'lo-de\, Peace of (1454) Treaty between Venice and Milan end�  ing the war of succession to the Milanese duchy in favor of Francesco  Sforza. It recognized Sforza as ruler of Milan and restored Venice�s ter�  ritories in northern Italy, including Brescia and Bergamo. It also provided  for a 25-year mutual defensive pact to maintain existing boundaries and  established an Italian League. The treaty created a balance of power  among Venice, Milan, Naples, Florence, and the Papal States, and it began  a 40-year period of relative peace.</p><p>Lodz Vwiich,\ English \'lodz\ City (pop., 2001 prelim.: 793,217), cen�  tral Poland. Located southwest of Warsaw, it was a village in the 14th  century and gained municipal rights in 1798. The Russian-ruled Congress  Kingdom of Poland established it as a centre of the textile industry in  1820, and by the late 19th century it was Poland�s leader in the produc�  tion of cotton textiles. It was occupied by the Germans during World Wars  I and II. It is now a cultural centre and Poland�s second largest city.</p><p>loess Vies, 'lo-3s\ Unstratified, geologically recent deposit of silty or  loamy material that is usually buff or yellowish brown and is deposited  chiefly by the wind. Loess is a sedimentary deposit composed largely of  silt-sized grains that are loosely cemented by calcium carbonate. It is usu�  ally homogeneous and highly porous and is traversed by vertical capil�  laries that permit the sediment to fracture and form vertical bluffs.</p><p>Loesser Vle-sorX, Frank (Henry) (b. June 29, 1910, New York, N.Y.,  U.S.�d. July 28, 1969, New York City) U.S. composer, librettist, and  lyricist. The son of a piano teacher, in 1936 he moved to Hollywood,  where he worked with Burton Lane, Jule Styne, Jimmy McHugh, and Hoagy  Carmichael. His wartime songs include �Praise the Lord and Pass the  Ammunition� and �What Do You Do in the Infantry?�; postwar hits  include �On a Slow Boat to China� and �Baby It�s Cold Outside� (Acad�  emy Award, 1949). His first Broadway musical was Where�s Charley?  (1948; film, 1952). In 1950 he produced Guys and Dolls (film, 1955), one  of the greatest American musicals. It was followed by The Most Happy  Fella (1956) and How to Succeed in Business Without Really Trying  (1962, Pulitzer Prize). His work for film includes the score for Hans  Christian Andersen (1952).</p><p>Loewe Vlo\, Frederick (b. June 10, 1901, Berlin, Ger.�d. Feb. 14,  1988, Palm Springs, Calif., U.S.) German-born U.S. songwriter. Son of a  Viennese tenor, Loewe was a piano prodigy; at age 13 he became the  youngest soloist ever to appear with the Berlin Philharmonic Orchestra.  He studied with Ferruccio Busoni and Eugene d�Albert. His song �Kat�  rina,� written at age 15, sold more than a million copies. Arriving in the  U.S. in 1924, he contributed music to Broadway revues. In 1942 he met  Alan Jay Lerner; their 18-year collaboration would produce five classic  musicals. Personal differences ended their partnership after Camelot  (1960), but they reunited to adapt their film Gigi (1958) for the stage  (1973) and to write songs for the film The Little Prince (1974).</p><p>Loewy \'lo-e\, Raymond (Fernand) (b. Nov. 5, 1893, Paris, Fr.�d.  July 14, 1986, Monaco) French-bom U.S. industrial designer. After  obtaining an advanced degree in electrical engineering, he immigrated in  1919 to New York City, where he worked as a fashion illustrator and  designer of department store window displays. He opened his own design  firm in 1929, and in the 1930s and �40s he designed a variety of house�  hold products with rounded corners and simplified, �streamlined� out�  lines. A refrigerator he designed for Sears, Roebuck &amp; Co. (1934) won first  prize at the 1937 Paris International Exposition. In later years his highly  functional designs for everything from locomotives to soda dispensers  helped shape U.S. industrial design.</p><p>Loffler Vlcef-lorV Friedrich (August Johannes) (b. June 24, 1852,  Frankfurt an der Oder, Prussia�d. April 9, 1915, Berlin, Ger.) German</p><p>bacteriologist. In 1884, with Edwin Klebs (1834-1913), he discovered the  organism that causes diphtheria. Simultaneously with Emile Roux (1853�  1933) and Alexandre Yersin (1863-1943), he indicated the existence of a  diphtheria toxin. His demonstration that some animals are immune to  diphtheria was basic to Emil von Behring�s work in developing antitox�  ins. Loffler also discovered the cause of some swine diseases and iden�  tified, with Wilhelm Schtitz, the organism that causes the horse disease  glanders. With Paul Frosch he found that foot-and-mouth disease is caused  by a virus (the first time a virus was found to be the agent of an animal  disease) and developed a serum against it.</p><p>loft Upper space within a building, often open on one side, used for stor�  age or other purposes (e.g., sleeping loft, hayloft). The term also refers  to one of the upper floors in a factory or warehouse, typically undivided  by partitions and now often converted to other uses, such as residences  or artists� studios. In churches the rood loft is a display gallery above the  rood screen (see cathedral), and a choir or organ loft is a gallery reserved  for church singers and musicians. In theaters, the loft is the area above  and behind the proscenium.</p><p>Lofting, Hugh (John) (b. Jan. 14, 1886, Maidenhead, Berkshire,  Eng.�d. Sept. 26, 1947, Santa Monica, Calif., U.S.) British-bom U.S.  author and illustrator. He lived principally in the U.S. from 1912. He is  known for his classic children�s books about Doctor Dolittle, a chubby,  gentle, eccentric physician to animals who learns their language the bet�  ter to treat them. He originally created the character to entertain his chil�  dren in letters he sent from the front during World War I. The Story of  Dr. Dolittle (1920) won instant success; it was followed by The Voyages  of Dr. Dolittle (1922, Newbery Medal), Dr. Dolittle in the Moon (1928),  and Dr. Dolittle�s Return (1933), among many other volumes.</p><p>log cabin Small, one-room house built of logs notched at the ends and  laid one upon another with the  spaces filled with plaster, moss, mor�  tar, mud, or dried manure. In North  America they were built by early set�  tlers, hunters, loggers, and other wil�  derness dwellers. They have also  been built in Europe, particularly  Scandinavia. Though designs vary, a  common style features a sloping,  single-gabled timbered roof and  small windows. Modern summer  cottages may be built of logs (or  given log-cabin siding) to achieve a  rustic effect.</p><p>Logan, James orig. Tah-gah-  jute (b. c. 1725, probably at  Shamokin, Pa.�d. 1780, near Lake  Erie) American Indian leader. He  was the son of the Oneida chief  Shikellamy, who was a friend of the  secretary of the Pennsylvania colony, James Logan (1674-1751). He  moved to the Ohio River valley, where he became friendly with Indians  and white settlers. After his family was massacred by a frontier trader in  1774, he led Indian raids on white settlements in Lord Dunmore's War. He  refused to participate in peace negotiations, sending his grievances in a  message known as �Logan�s Lament.� He was allied with the British in  the American Revolution.</p><p>Logan, Mount Peak, St. Elias Mountains, southwestern Yukon Terri�  tory, Canada, near the Alaskan boundary. Reaching 19,524 ft (5,951 m),  it is the highest mountain in Canada and is second in North America only  to Mount McKinley. It is located in Kluane National Park, which occupies  8,500 sq mi (22,000 sq km). The summit was first reached in 1925. The  peak was named for William Logan, founder of the Geological Survey of  Canada.</p><p>loganberry Bramble plant ( Rubus loganobaccus ) of the rose family. It  originated in Santa Cruz, Calif., in 1881, apparently as a natural hybrid  between the wild blackberry of the Pacific coast and the red raspberry. It is  grown in large quantities in Oregon and Washington and is cultivated in  Britain and Tasmania. The loganberry is a vigorous, nearly trailing,  blackberry-like plant with compound leaves and prickly canes. Its wine-  red, tart berries are canned, frozen, used in preserves or pies, or made into  wine.</p><p>Log cabin, Abraham Lincoln's boyhood  home, Knob Creek, Kentucky, origi�  nally built early 19th century.</p><p>WETTACH/SHOSTAL</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>logarithm &#x25BA; Loki I 1131</p><p>logarithm In mathematics, the power to which a base must be raised  to yield a given number (e.g., the logarithm to the base 3 of 9, or log 3 9,  is 2, because 3 2 = 9). A common logarithm is a logarithm to the base 10.  Thus, the common logarithm of 100 (log 100) is 2, because 10 2 = 100.  Logarithms to the base e, in which e = 2.71828..., called natural loga�  rithms (In), are especially useful in calculus. Logarithms were invented  to simplify cumbersome calculations, since exponents can be added or  subtracted to multiply or divide their bases. These processes have been  further simplified by the incorporation of logarithmic functions into digi�  tal calculators and computers. See also John Napier.</p><p>loggia \'lo-je-9\ Hall, gallery, or porch open to the air on one or more  sides. It evolved in the Mediterranean region as an open sitting room with  protection from the sun. It is often a roofed, arcaded open gallery on an  upper story overlooking a court, though it can also be a separate arcaded  or colonnaded structure. In medieval and Renaissance Italy, it was often  used in conjunction with a public square, as in Florence�s Loggia dei  Lanzi (begun 1376).</p><p>logic Study of inference and argument. Inferences are rule-governed  steps from one or more propositions, known as premises, to another  proposition, called the conclusion. A deductive inference is one that is  intended to be valid, where a valid inference is one in which the conclu�  sion must be true if the premises are true (see deduction; validity). All other  inferences are called inductive (see induction). In a narrow sense, logic is  the study of deductive inferences. In a still narrower sense, it is the study  of inferences that depend on concepts that are expressed by the �logical  constants,� including: (1) propositional connectives such as �not,� (sym�  bolized as � i), �and� (symbolized as a), �or� (symbolized as v), and �if-  then� (symbolized as z&gt;), (2) the existential and universal quantifiers,  �(3x)� and �(Vx),� often rendered in English as �There is an x such that  ...� and �For any (all) x, respectively, (3) the concept of identity  (expressed by �=�), and (4) some notion of predication. The study of the  logical constants in (1) alone is known as the propositional calculus; the  study of (1) through (4) is called first-order predicate calculus with iden�  tity. The logical form of a proposition is the entity obtained by replacing  all nonlogical concepts in the proposition by variables. The study of the  relations between such uninterpreted formulas is called formal logic. See  also deontic logic; modal logic.</p><p>logic, many-valued Formal system in which the well-formed formu�  lae are interpreted as being able to take on values other than the two clas�  sical values of truth or falsity. The number of values possible for well-  formed formulae in systems of many-valued logic ranges from three to  uncountably many.</p><p>logic, philosophy of Philosophical study of the nature and scope of  logic. Examples of questions raised in the philosophy of logic are: �In  virtue of what features of reality are the laws of logic true?�; �How do  we know the truths of logic?�; and �Could the laws of logic ever be fal�  sified by experience?� The subject matter of logic has been variously  characterized as the laws of thought, �the rules of right reasoning,� �the  principles of valid argumentation,� �the use of certain words called logi�  cal constants,� and �truths based solely on the meanings of the terms they  contain.�</p><p>logic design Basic organization of the circuitry of a digital computer.  All digital computers are based on a two-valued logic system�1/0, on/off,  yes/no (see binary code). Computers perform calculations using compo�  nents called logic gates, which are made up of integrated circuits that  receive an input signal, process it, and change it into an output signal. The  components of the gates pass or block a clock pulse as it travels through  them, and the output bits of the gates control other gates or output the  result. There are three basic kinds of logic gates, called �and,� �or,� and  �not.� By connecting logic gates together, a device can be constructed  that can perform basic arithmetic functions.</p><p>logical positivism Early school of analytic philosophy, inspired by  David Hume, the mathematical logic of Bertrand Russell and Alfred North  Whitehead, and Ludwig Wittgenstein�s Tractatus (1921). The school, for�  mally instituted at the University of Vienna in a seminar of Moritz Schlick  (1882-1936) in 1922, continued there as the Vienna Circle until 1938. It  proposed several revolutionary theses: (1) All meaningful discourse con�  sists either of (a) the formal sentences of logic and mathematics or (b) the  factual propositions of the special sciences; (2) Any assertion that claims  to be factual has meaning only if it is possible to say how it might be  verified; (3) Metaphysical assertions, including the pronouncements of</p><p>religion, belong to neither of the two classes of (1) and are therefore  meaningless. Some logical positivists, notably A.J. Ayer, held that asser�  tions in ethics (e.g., �It is wrong to steal�) do not function logically as  statements of fact but only as expressions of the speaker�s feelings of  approval or disapproval toward some action. See also Rudolf Carnap;  emotivism; verifiability principle.</p><p>logicism Vla-ji-.si-zomN In the philosophy of mathematics, the thesis that  all mathematical propositions are expressible as or derivable from the  propositions of pure logic. Gottlob Frege attempted to establish the thesis  in his Die Grundlagen der Arithmetik (1884) and other works; Bertrand  Russell argued for logicism in The Principles of Mathematics (1903) and  attempted a formal proof with Alfred North Whitehead in Principia Math-  ematica (1910-13).</p><p>logistic system See formal system</p><p>logistics \lo-'jis-tiks, b-'jis-tiks\ In military science, all the activities of  armed-force units in support of combat units, including transport, supply,  communications, and medical aid. The term, first used by Henri Jomini,  Alfred Thayer Mahan, and others, was adopted by the U.S. military in  World War I and gained currency in other nations in World War II. Its  importance grew in the 20th century with the increasing complexity of  modern warfare. The ability to mobilize large populations has escalated  military demands for supplies and provisions, and sophisticated technol�  ogy has added to the cost and intricacy of weapons, communications sys�  tems, and medical care, creating the need for a vast network of support  systems. In World War II, for instance, only about three in 10 U.S. sol�  diers served in a combat role.</p><p>Logone \lo-'gon\ River River, north-central Africa. The chief tributary  of the Chari River of the Lake Chad basin in equatorial Africa, it drains  northeastern Cameroon and Chad. It flows 240 mi (390 km) northwest to  join the Chari at N'Djamena, Chad. It is seasonally navigable for small  steamers below Bongor.</p><p>logos (Greek: �word,� �reason,� �plan�) In Greek philosophy and the�  ology, the divine reason that orders the cosmos and gives it form and  meaning. The concept is found in the writings of Heracleitus (6th century  bc) and in Persian, Indian, and Egyptian philosophical and theological  systems as well. It is particularly significant in Christian theology, where  it is used to describe the role of Jesus as the principle of God active in  the creation and ordering of the cosmos and in the revelation of the divine  plan of salvation. This is most clearly stated in the Gospel of John the  Apostle, which identifies Christ as the Word (Logos) made flesh.</p><p>Logrono \lo-'gro-nyo\ City (2001: 133,058), capital of La Rioja autono�  mous community, Spain. Originating in Roman times, it owed its growth  during the Middle Ages to its position on the pilgrimage route to Santi�  ago de Compostela. An ancient walled town, it is a trade centre in an agri�  cultural region and is known for its Rioja wine.</p><p>Lohengrin \'\d-dn-,gren,\ English Vlo-on-.grinV Hero-knight of medieval  Germanic legends. He was called the knight of the swan because he  arrived in a boat drawn by a swan to help a noble lady in distress. He  married her but forbade her to ask his origin; when she forgot this prom�  ise, he left her, never to return. The first version of his legend appeared  c. 1210 in Wolfram von Eschenbach�s Parzival, in which the swan knight  was the son and heir of Parzival (Perceval).

The longest river in  France, it flows north and west for 634 mi (1,020 km) to the Bay of Bis�  cay, which it enters through a wide estuary below Saint-Nazaire. Embank�  ments were built as early as the 12th century, and in subsequent centuries  it was used extensively for the transport of goods. A canal system built  in the 17th and 18th centuries is inadequate for modem vessels.</p><p>loka \'lo-ko\ In Hinduism, the universe or any particular division of it.  The most common division of the universe is the tri-loka, or three worlds  (heaven, earth, and atmosphere, or heaven, world, and netherworld), each  of which is divided into seven regions. Sometimes, instead of the tri-loka,  14 worlds are envisioned, seven above the earth and seven below. What�  ever the division, it illustrates the basic Hindu concept of hierarchically  ordered worlds.</p><p>Loki Vlo-ke\ In Norse mythology, a trickster who was able to change his  shape and sex.

Loki created a  female, Angerboda, with whom he produced three evil progeny: Hel, the  goddess of death; Jormungand, the evil serpent surrounding the world;  and Fenrir, the wolf.</p><p>Lollards Followers of John Wycliffe in late medieval England. The pejo�  rative name (from Middle Dutch lollaert, �mumbler�) had been applied  earlier to European groups suspected of heresy. The first Lollard group  centred on some of Wycliffe�s colleagues at Oxford led by Nicholas of  Hereford. In 1382 the archbishop of Canterbury forced some of the  Oxford Lollards to renounce their views, but the sect continued to mul�  tiply. The accession of Henry IV in 1399 signaled a wave of repression.  In 1414 a Lollard rising was quickly defeated by Henry V; it brought  severe reprisals and marked the end of the Lollards� overt political influ�  ence. A Lollard revival began c. 1500, and by 1530 the old Lollard and  the new Protestant forces had begun to merge. The Lollard tradition pre�  disposed opinion in favor of Henry VIII �s anticlerical legislation. The Lol�  lards were responsible for a translation of the Bible by Nicholas of  Hereford, and their core teachings included an emphasis on personal faith  and the authority of the Bible and the rejection of clerical celibacy, tran-  SUBSTANTIATION , and INDULGENCES.</p><p>Lomax Vlo- l maks\ / John (b. Sept. 23, 1867, Goodman, Miss., U.S.�d.  Jan. 26, 1948, Greenville, Miss.) U.S. ethnomusicologist. He attended  Harvard University and soon thereafter began publishing collections of  cowboy songs. In the 1930s he and his teenage son Alan (1915-2002)  collected folk songs of the Southwest and Midwest. Jelly Roll Morton,  Leadbelly, and Muddy Waters were perhaps the most significant of their  many important discoveries; the Lomaxes� archive of Morton�s perfor�  mance and storytelling was of particular significance. Both men did  important work at the Library of Congress�s Archive of Folk Music. Their  many books and anthologies spurred the folk music revival of the 1950s  and �60s.</p><p>Lombard Any member of a Germanic people who from 568 to 774 ruled  a kingdom in the region of Lombardy. Originally a pastoral tribe from  northwestern Germany, the Lombards migrated southward and adopted  an imperial military system. In the 6th century they moved into northern  Italy, conquering the cities that had been left defenseless after the over�  throw of the Ostrogoths by the Byzantine Empire. In the 8th century Liud-  prand, probably the greatest of the Lombard kings, steadily reduced the  area of Italy still under Byzantine rule. When the Lombard kings invaded  papal territories. Pope Adrian I sought aid from Charlemagne. In 773 the  Franks besieged the Lombard capital, capturing Desiderius, the Lombard  king; Charlemagne became king of the Lombards as well as of the Franks,  and Lombard rule in Italy ended.</p><p>Lombard, Carole orig.

She made her screen debut in A Perfect Crime (1921) and  appeared in comedy shorts from 1925. She starred in the classic screw�  ball comedy Twentieth Century (1934), which showcased her unique  blend of sophisticated glamour and earthy audacity and established her as  a leading comic actress. She appeared in a series of popular comedies,  including My Man Godfrey (1936), Nothing Sacred (1937), Mr. and Mrs.  Smith (1941), and To Be or Not to Be (1942). She married Clark Gable in  1939.

Founded in 1167, it was backed  by Pope Alexander III, who saw it as an ally against Emperor Frederick I  Barbarossa. After several military setbacks at the hands of the league,  Frederick was forced to grant the Lombard cities communal liberties and  jurisdiction under the Peace of Constance. The league again was renewed  in 1226 and resisted Frederick ll's attempt to reassert imperial power in  northern Italy.</p><p>Lombardi, Vince(nt Thomas) (b. June 11, 1913, Brooklyn, N.Y.,  U.S.�d.

June 19, 1902, London, Ont., Can.�d.  Nov. 5, 1977, Houston, Texas, U.S.) Canadian-born U.S. bandleader. He  trained as a violinist and in 1917 formed his band, the Royal Canadians.  They began broadcasting nationally from Chicago in 1927, and from 1929  he was the winter attraction at New York City�s Roosevelt Grill, a book�  ing repeated for more than 30 years. He later moved to the Waldorf-  Astoria Hotel, continuing the famous New Year�s Eve broadcasts, begun  in 1954, that climaxed with �Auld Lang Syne.� Though derided by crit�  ics as the �king of com,� Lombardo gained long-lasting popularity by  conducting what was billed as �the sweetest music this side of heaven.�</p><p>Lombardy \Tam-bor-de\ Region (pop., 2003 est.: 9,108,645), northern  Italy. Bounded on the north by Switzerland, it contains many Alpine peaks  as well as the fertile valley of the Po River. Its capital is Milan. Inhabited  by Celtic peoples from the 5th century bc, it was conquered by Rome  after the Second Punic War and became part of Cisalpine Gaul. In ad  568-774 it was the centre of the kingdom of the Lombards. During the  Middle Ages several of its towns became self-governing municipalities;  they formed the Lombard League in the 12th century and won autonomy  by defeating Frederick I Barbarossa in 1176. The area was later ruled by  Spain (1535-1713), Austria (1713-96), and France (1796-1814). In 1859  Lombardy joined the newly unified Italy. Italy�s most populous region, it  is a thriving commercial area centred on Milan.</p><p>Lombok Vlom-.bokV Island, Indonesia. It is one of the Lesser Sunda  Islands, separated from Bali by the Lombok Strait and from Sumbawa by  the Alas Strait. It is 70 mi (115 km) long and 50 mi (80 km) wide and  occupies an area of 2,098 sq mi (5,435 sq km). It is divided by two moun�  tain chains; its northern range includes Mount Rindjani (12,224 ft [3,726  m]), Indonesia�s tallest mountain. It was ruled by the sultan of Makasar  in 1640. The Balinese later seized control and established four kingdoms  there; the Dutch ruled the kingdom of Mataram from 1843 and gained  control of the entire island by the late 19th century. Following World War  II, it became part of Indonesia.</p><p>Lome \lo-'ma\ City (pop., 2003 est.: 676,400; urban agglom.: 749,700),  capital of Togo. Located on the Gulf of Guinea in southwestern Togo, it  was chosen as the capital of German Togoland in 1897 and developed as  an administrative and commercial centre. Its port was modernized in the  1960s, and its deepwater harbour is a major shipping centre. It is the site  of the University of Benin (1965).</p><p>Lomenie de Brienne Mo-ma-'ne-do-bre-'enV Etienne Charles de</p><p>(b. Oct. 9, 1727, Paris, France�d.

Unable to cope with the worsening financial crisis, he resigned in favour  of Jacques Necker. Made archbishop of Sens and then cardinal (1788), he  was one of the few prelates who took the oath to the Civil Constitution of  the Clergy (1790). He died in prison during the Reign of Terror.</p><p>Lomond Vlo-monV Loch Lake, Scotland. Located at the southern edge  of the Highlands, it is the country�s largest lake 24 mi (39 km) long and  0.75 to 5 mi (1.2 to 8 km) wide, with an area of 27 sq mi (70 sq km). It  drains by the short River Leven into the Firth of Clyde at Dumbarton.

April 15, 1765, St. Petersburg) Rus�  sian scientist, poet, and grammarian, considered the first great Russian  linguistic reformer. Educated in Russia and Germany, he established what  became the standards for Russian verse in the Letter Concerning the Rules  of Russian Versification. In 1745 he joined the faculty at the St. Peters�  burg Imperial Academy of Sciences, where he made substantial contri�  butions to the physical sciences. He later wrote a Russian grammar and  worked to systematize the Russian literary language, which had been an  amalgam of Church Slavonic and Russian vernacular. He also reorganized  the academy, founded Moscow State University (which now bears his  name), and created the first coloured-glass mosaics in Russia.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Lon Nol &#x25BA; Long I 1133</p><p>Lon Nol (b.

A magistrate  in the French colonial service, he became successively head of the  national police (1951), army chief of staff (1955), and commander in chief  (1960). He was twice premier (1966-67, 1969-70) under Norodom Sih�  anouk. In 1970 he was the chief architect of the U.S.-supported coup that  deposed Sihanouk. He abandoned Sihanouk�s policy of neutrality in the  Vietnam War and threw Cambodia�s support behind the U.S. and South  Vietnam. In 1972 he assumed total power in Cambodia; he fled to the  U.S. in 1975 when the Khmer Rouge takeover was imminent.</p><p>London officially Greater London Capital and largest city (pop.,  2001: 7,172,036) of the United Kingdom, situated in southeastern  England on the River Thames. It is the political, industrial, cultural, and  financial centre of the country. Formally known as the metropolitan  county of Greater London (established 1965), it has an area of 659 sq mi  (1,706 sq km) and consists of two regions: Inner London comprises 14  of London�s 33 boroughs (including the original City of London), and  Outer London encompasses the other 19 boroughs. Greater London is an  administrative entity, with an elected mayor and assembly. Founded by  the Romans as Londinium in the 1st century ad, it passed to the Saxons  in the 5th-6th century. The Danes invaded England and London in 865.  Following the Norman Conquest (1066), William I (the Conqueror) estab�  lished the central stronghold of the fortress known as the Tower of Lon�  don. Norman kings selected Westminster as their seat of government. The  church known as Westminster Abbey had been built earlier by Edward the  Confessor. The largest city in Europe north of the Alps by 1085, it was  struck by the Black Death in 1348�49. Trade grew significantly in the  mid-16th century, fueled by the establishment of Britain�s overseas  empire. In 1664-65 the plague killed about 70,000 Londoners, and in  1666 the Great Fire of London consumed five-sixths of the City of Lon�  don; it was afterward rebuilt (see Christopher Wren). London was the cen�  tre of world trade from the late 18th century to 1914. It opened the world�s  first electric underground railway in 1890. Severely damaged by German  bombs in the Battle of Britain during World War II, it was again rebuilt  and grew rapidly in the postwar period. Among its sites of interest are  Buckingham Palace, the Tate galleries, the National Gallery, the British  Museum, and the Victoria and Albert Museum.</p><p>London City (pop., 2001: metro area, 432,451), southeastern Ontario.  It lies on the Thames River, near several of the Great Lakes. Its name and  site were chosen in 1792 for the location of a capital of Upper Canada,  but the plans failed to materialize. First settled in 1826, it was incorpo�  rated as a city in 1855. It became an important transportation and indus�  trial centre as a result of its interlake location. It is the seat of the  University of Western Ontario.</p><p>London, Great Fire of See Great Fire of London  London, Great Plague of See Great Plague of London</p><p>London, Jack orig. John Griffith Chaney (b. Jan. 12, 1876, San  Francisco, Calif., U.S.�d. Nov. 22,</p><p>1916, Glen Ellen, Calif.) U.S. nov�  elist and short-story writer. Born to  poverty, the largely self-educated  London became a sailor, hobo, Alas�  kan gold miner, and militant social�  ist. He gained a wide audience with  his first book, The Son of the Wolf  (1900), and the story �To Build a  Fire� (1908). Thereafter he wrote  steadily; his 50 books of fiction and  nonfiction, including many romantic  depictions of elemental struggles for  survival as well as socialist tracts,  include The Call of the Wild (1903),</p><p>The Sea-Wolf (1904), White Fang  (1906), The Iron Heel (1907), Mar�  tin Eden (1909), and Burning Day�  light (1910). Though his work  brought him wealth and fame, his suicide at age 40 was the result of alco�  holism and mounting debt.</p><p>London, Treaty of (April 1915) Secret treaty between neutral Italy  and the Allied forces of France, Britain, and Russia to bring Italy into  World War I. The Allies wanted Italy�s participation because of its bor�</p><p>der with Austria. Italy was promised Trieste, southern Tyrol, northern  Dalmatia, and other territories in return for a pledge to enter the war within  a month. Despite the opposition of most Italians, who favoured neutral�  ity, Italy joined the war against Austria-Hungary in May.</p><p>London, University of Federation of more than 50 British institu�  tions of higher learning, located primarily in London, England. It was  established by liberals and religious dissenters in 1828, and it accepted  for enrollment Roman Catholics, Jews, and other non-Anglicans. The first  two colleges were University College and King�s College. From 1849 a  student enrolled in any university in the British Empire could be awarded  a University of London degree after examination. By the early 20th cen�  tury many institutions had become affiliated with the university, includ�  ing Bedford College, the first British university to grant degrees to  women; the London School of Economics and Political Science, now an  internationally renowned centre for the social sciences; and three other  institutions that later became the Imperial College of Science and Tech�  nology.</p><p>London Bridge Any of several successive structures spanning the  River Thames. The Old London Bridge of nursery-rhyme fame was built  by Peter of Colechurch between 1176 and 1209, replacing an earlier tim�  ber bridge. Because of obstructions encountered in building the coffer�  dams, the arch spans varied from 15 to 34 ft (4.6-10.4 m); the uneven  construction resulted in frequent need for repair, but the bridge survived  more than 600 years. Its roadway was loaded with a jumble of houses and  shops, many projecting out over the river. It was demolished and replaced  in the 1820s by New London Bridge, designed and built by John Rennie,  Sr. (1761-1821), and his son John Rennie, Jr. (1794-1874). In the 1960s  it was again replaced; the old masonry facing was dismantled and  reerected at Lake Havasu City, Ariz., as a tourist attraction.</p><p>London Naval Conference (Jan. 21-April 22, 1930) Conference  held in London to discuss naval disarmament and review the treaties of  the Washington Conference. Representatives of Britain, the U.S., France,  Italy, and Japan agreed to regulate submarine warfare and to place limits  on new construction of cruisers, destroyers, submarines, and other war�  ships. A treaty limiting battleship size was not signed, and the treaties  renewed in 1935 were canceled on the outbreak of World War II.</p><p>London Stock Exchange London marketplace for securities. It was  formed in 1773 by a group of stockbrokers who had been doing business  informally in local coffeehouses. In 1801 its members raised money for  construction of a building in Bartholomew Lane; they established rules  for the exchange the following year. In 1973 the London Stock Exchange  merged with several regional British stock exchanges. In 1991 the  exchange replaced its governing council with a board of directors, and it  became a public limited company.</p><p>Londonderry locally and historically Derry District (pop., 2001:  105,066), northwestern Northern Ireland. It is also the name of a former  traditional county, colonized by the English in 1609; the 1973 adminis�  trative reorganization broke up the county into several districts, includ�  ing Londonderry. Bordered by the Irish republic and Lough Foyle, it is  centred around the seaport city of Londonderry. In 1969 the old city and  the adjacent area were merged administratively, and in 1973 it became  one of Northern Ireland�s 26 districts.</p><p>Londonderry locally and historically Derry Seaport (pop., 1995 est.:  77,000) and district seat of Londonderry, Northern Ireland. St. Columba  established a monastery there in the 6th century, but the settlement was  repeatedly destroyed by Norse invaders. In 1600 an English force seized  the city; shortly thereafter James I of England granted the city to the citi�  zens of London, who brought in Protestant settlers, and it was then that  it became officially known as Londonderry. Growth of the modern city  dates from the 1850s, when linen shirt making became important, and  clothing manufacture remains a major industry. Home to two cathedrals,  Anglican and Roman Catholic, it has been the site of terrorist violence.  Steeped in the region�s political turmoil, controversy surrounds the city�s  name. The British government officially refers to the city and district as  Londonderry City, but since 1984 the nationalist-controlled city council  has called itself the Derry City Council.</p><p>Long, Huey (Pierce) (b.

Laid out as Willmore City in 1880 and  incorporated in 1888, it was renamed for its 8.5-mi (13.5-km) beach. The  discovery of oil nearby in 1921 led to rapid growth. An earthquake in  1933 caused extensive damage. It is connected to the Los Angeles harbour  by the Cerritos Channel. The British ocean liner Queen Mary has been  moored in the harbour since 1969.</p><p>long-distance running In track and field, any foot race over 5,000  m in length. Marathons and cross-country running are also considered  long-distance events. Women rarely ran in races beyond 3,000 m until the  late 20th century.</p><p>Long Island Island (pop., 2000: 7,448,618), southeastern New York,  U.S., lying between Long Island Sound and the Atlantic Ocean. It has four  counties: Kings, Queens, Nassau, and Suffolk. Kings County (the borough  of Brooklyn) and Queens County (the borough of Queens) form part of  New York City. At its western end it is separated from the Bronx and Man�  hattan by the East River and from Staten Island by the Narrows. It is 118  mi (190 km) long, 12-23 mi (19-37 km) wide, and has an area of 1,401  sq mi (3,629 sq km). Its eastern portion has many beaches; it serves as a  recreation area for New York City. Its southern shore, lined by sand spits  (see Fire Island), shelters several bays, including Jamaica Bay. Originally  inhabited by Indians (mostly Delaware), it was included in a grant to the  Plymouth Co. It was settled by Dutch and English, but the whole island  became part of the British colony of New York in 1664. It was the site of  the Battle of Long Island (Aug. 27, 1776), an American defeat in the  American Revolution.</p><p>Long Island Sound Body of water between the southern shore of  Connecticut and the northern shore of Long Island, New York, U.S. It  connects with the East River and with Block Island Sound. Covering  1,180 sq mi (3,056 sq km), it is 90 mi (145 km) long and 3-20 mi (5-32  km) wide. Its shores have many residential communities and summer  resorts.</p><p>long jump or broad jump Track-and-field sport consisting of a hori�  zontal jump for distance. It was formerly performed from both standing  and running starts, as separate events, but the standing long jump is no  longer included in major competitions. The running long jump was an  event in the Olympic Games of 708 bc and in the modern Games from 1896.  In 1948 the women�s long jump became an Olympic event.</p><p>Long March (1934-35) Trek of 6,000 mi (10,000 km) by Chinese  Communists, resulting in the relocation of their revolutionary base from  southeastern China to northwestern China and the emergence of Mao  Zedong as their undisputed leader. Having withstood four of Chiang Kai-  shek�s campaigns against their base area, the Communists were nearly  defeated by his fifth attack. The remaining 85,000 troops broke through  Nationalist lines and fled first westward under Zhu De and then north under  Mao. By the time Mao arrived at Shaanxi, he was followed by only about  8,000 survivors, most of the rest having been killed by fighting, disease,  and starvation (among the casualties were Mao�s two children and a</p><p>brother). At their new base the Communists were able to build up their  strength at a safe remove from the Nationalists in preparation for their  eventual victory in 1949.</p><p>Long Parliament Session of the English Parliament summoned in  November 1640 by Charles I, so named to distinguish it from the Short  Parliament of April-May 1640. Charles called the session to raise the  money needed for his war against the Scots. Resistant to Charles�s  demands, the Parliament caused the king�s advisers to resign and passed  an act forbidding its own dissolution without its members� consent. Ten�  sion between the king and Parliament increased until the English Civil War  broke out in 1642. After the king�s defeat (1646), the army, led by Tho�  mas Pride, exercised political power and in 1648 expelled all but 60 mem�  bers of the Long Parliament. The remaining group, called the Rump,  brought Charles to trial and execution (1649); it was forcibly ejected in  1653. In 1659, after the end of Oliver Cromwell�s protectorate, the Parlia�  ment was reestablished; those who were excluded in 1648 were restored  to membership. The Parliament dissolved itself in 1660.</p><p>longbow Leading missile weapon of the English from the 14th century  into the 16th century. Probably of Welsh origin, it was usually 6 ft (2 m)  tall and shot arrows more than a yard long. The best were made of yew,  might require a force of 100 lbs (45 kg) to draw, and had an effective  range of 200 yards (180 m). English archers used longbows in the Hun�  dred Years' War, and the weapon played an important role in the battles  of Crecy, Poitiers, and Agincourt. See also bow and arrow, crossbow.</p><p>(b.

His Voices of the  Night (1839), containing �The Psalm  of Life� and �The Light of the Stars,�  first won him popularity. Ballads and  Other Poems (1841), including �The  Wreck of the Hesperus� and �The  Village Blacksmith,� swept the  nation, as did his long poem Evan�  geline (1847). With Hiawatha  (1855), The Courtship of Miles  Standish (1858), and Tales of a Way-  side Inn (1863), including �Paul  Revere�s Ride,� he became the best�  loved American poet of the 19th cen�  tury. He later translated Dante�s  Divine Comedy (1867) and published his intended masterpiece, Christus,  a trilogy on Christianity (1872).

Popular for their  charm and seeming naivete, his paintings have a Rococo sense of the inti�  mate and manifest the interest in social observation characteristic of the  Enlightenment. He also painted landscapes and portraits.</p><p>longhouse Traditional communal dwelling of the Iroquois Indians until  the 19th century. The longhouse was a rectangular box built out of poles,  with doors at each end and saplings stretched over the top to form the  roof, the whole structure being covered with bark. It was about 20 ft (6  m) wide and could be more than 200 ft (60 m) in length, depending on  the number of families living in it. Down the middle of the house were  fires, which were shared by families on either side. The term is also  applied today to an Iroquois building designated as church and meeting  hall, though its form is entirely different.

Construction began late in the Northern Wei dynasty (ad  386-535) and continued sporadically through the 6th century and the Tang  dynasty. Delicately crafted to create ethereal effects in stone, the temples  contain images of the Buddha clothed as a Chinese scholar. Work at Long-  men culminated in 672-675 with the construction of a monumental shrine  known as Fengxian Si, which includes a seated Buddha more than 35 ft  (10.7 m) high.</p><p>Longshan culture or Lung-shan culture (2500-1900 bc)  Neolithic culture of China�s Huang He (Yellow River) valley. Large sites  with rammed-earth walls have been found. Characteristic Longshan pot�  tery has thin walls and is well crafted; there are tall-stemmed black cups  with eggshell-thin walls as well as polished black beakers. Oracle bones  were used for divination. There is evidence of differentiation in social sta�  tus, and jade artifacts and traces of metallurgy have been found.</p><p>longship or Viking ship Sail-and-oar vessel widely used in northern  Europe for more than 1,500 years. It was a 45-75-ft (14-23-m) galley  with up to 10 oars on a side, a square sail, and a 50-60-man capacity.  Double-ended and built with overlapped planks, it was exceptionally  sturdy in high seas. Examples have been found from as early as 300 bc.  It carried the Vikings on their piratical raids of the 9th century and bore  Leif Eriksson to America in 1000. Dutch, French, English, and German  merchants and warriors also used it.</p><p>Longstreet, James (b. Jan. 8, 1821, Edgefield District, S.C., U.S.�d.  Jan. 2, 1904, Gainesville, Ga.) U.S. army officer. He graduated from West  Point but resigned from the U.S. Army when South Carolina seceded.  Appointed brigadier general in the Confederate army, he fought in the  battles of Bull Run, Antietam, and Fredericksburg. He was second in com�  mand to Robert E. Lee at the Battle of Gettysburg, where his delay in  attacking contributed to the Confederate defeat. He later directed the Con�  federate attack at Chickamauga. He was badly wounded in the Battle of  the Wilderness but later resumed his command. He surrendered with Lee  at Appomattox Court House. He later served as U.S. minister to Turkey  (1880-81) and commissioner of Pacific railways (1898-1904).</p><p>Lonnrot \Tcen-rutV Elias (b. April 9, 1802, Sammatti, Swedish  Finland�d. March 19, 1884, Sammatti, Russian Finland) Finnish folk�  lorist and philologist. While serving as a medical officer for 20 years in  a remote part of eastern Finland, Lonnrot collected linguistic information  and folk poetry from the region�s inhabitants. Believing that the short  poems were fragments of a continuous epic, he added connective mate�  rial of his own and assembled them into the Kalevala (1835, enlarged  1849), which became the Finnish national epic. He also published Old  Songs and Ballads of the Finnish People (1840�41) and other collections.</p><p>Lonsdale, Dame Kathleen orig. Kathleen Yardley (b. Jan. 28,  1903, Newbridge, County Kildare, Ire.�d. April 1, 1971, London, Eng.)  Irish-born British crystallographer. In 1929 her X-ray crystallography  techniques established the regular hexagonal arrangement of carbon atoms  in molecules of benzene compounds. She developed a technique with  which she measured (to seven figures) the distance between carbon atoms  in diamond. She also applied crystallographic techniques to medical prob�  lems, in particular the study of bladder stones and certain drugs. In 1945  she became the first woman elected to the Royal Society of London, and  in 1956 she was created Dame of the British Empire.</p><p>loofah or luff a \Tii-fa\ Any of six species of annual climbing vines,  also called vegetable sponge or sponge gourd, that make up the genus  Luff a in the gourd family, native to the Old World tropics. Two species  cultivated in temperate areas (L. acutangula and L. aegyptiaca ) produce  1 -ft (30-cm) cucumber-shaped fruits. Edible and greenish when young,  these fruits become straw-coloured with age. On removal of the skin, pulp,  and seeds, there remains a complex of closely netted vascular bundles  (food- and water-carrying tubes) that resembles a sponge in texture. This  spongelike product is used for bathing, for washing dishes, and as an  industrial fibre.</p><p>loom Machine for weaving cloth. The earliest looms, from the 5th mil�  lennium bc, consisted of bars or beams forming a frame to hold a num�  ber of parallel threads in two alternating sets. By raising one set of these  threads (which together formed the warp), it was possible to run a cross  thread (a weft, or filling) between them. A shuttle carried the filling strand</p><p>through the warp. The fundamental operation of the loom remained  unchanged, but over centuries many improvements were introduced in  both Asia and Europe. The drawloom, probably invented in Asia for silk  weaving, provided a means for raising warp threads in groups as required  by a pattern. In the 18th century Jacques de Vaucanson and J.-M. Jacquard  mechanized this function by the ingenious use of punched cards; the cards  programmed the mechanical drawboy, saving labour and eliminating  errors (see Jacquard loom). In England the inventions of John Kay (flying  shuttle), Edmund Cartwright (power drive), and others contributed to the  Industrial Revolution, in which the loom and other textile machinery played  a central role.</p><p>weft</p><p>cross</p><p>beam</p><p>breast  beam</p><p>motion handle crosspiece</p><p>head roller</p><p>upright</p><p>beater</p><p>back</p><p>beam</p><p>beater</p><p>handtree</p><p>shuttle</p><p>cloth</p><p>roller</p><p>warp</p><p>roller</p><p>handle</p></section><section><p>ratchet</p><p>ratchet</p><p>wheel</p><p>Principal parts of a traditional hand loom.</p><p>� MERRIAM-WEBSTER INC.</p><p>loon or diver Any of four species (genus Gavia ) of diving birds of  North America and Eurasia. Loons  range in length from 2 to 3 ft (60-90  cm). They have small pointed wings,  webs between the front three toes,  legs placed far back on the body,  making walking awkward, and thick  plumage that is mainly black or gray  above and white below. They feed  mainly on fishes, crustaceans, and  insects. Almost wholly aquatic, they  can swim long distances underwater  and can dive to a depth of 200 ft (60  m). They are generally found singly  or in pairs, but some species winter  or migrate in flocks. They are known  for their eerie, �laughing� cries.</p><p>looper or cankerworm or inch worm Larva of any member of a  large, widespread group (mostly in the family Geometridae, with some in  the family Noctuidae) of moths.

Opposed to both Art Nou�  veau and Beaux-Arts historicism, he announced as early as 1898 his inten�  tion to avoid the use of unnecessary ornament. His Steiner House in  Vienna (1910) has been referred to by some architectural historians as the  first completely modem dwelling; the main (rear) facade is a symmetri�  cal, skillfully balanced composition of rectangles.

U.S. novelist and screenwriter. She was a child  actress; at an early age she also began contributing sketches and articles  to various periodicals. By age 20 she was a professional screenwriter for  silent films. Her first novel, Gentlemen Prefer Blondes (1925), brought  fame to Loos and her central character, the naive gold digger Lorelei Lee;  a musical version (1949) starred Carol Channing (b. 1921), and a film  (1953) starred Marilyn Monroe. Loos�s later film scripts included Blos�  soms in the Dust (1941) and I Married an Angel (1942). She also wrote  two memoirs, A Girl Like I (1966) and Kiss Hollywood Good-Bye (1974).</p><p>loosestrife Any ornamental plant of the family Lythraceae, especially  in the genera Lythrum and Decodon , and two genera of the primrose fam�  ily (.

Its branched stem bears whorls of narrow, pointed, stalkless  leaves and ends in tall, tapering spikes of red-purple flowers. Introduced  into North America early in the 19th century, it has become a noxious  weed in many parts of the U.S. and Canada because its dense growth out-  competes native wetland vegetation that provides food and habitat for  wildlife.</p><p>Lopez (Michelsen), Alfonso (b.

As president, he emphasized  attraction of foreign investment, tax concessions to stimulate industrial  development, creation of nonagricultural jobs, and exploitation of oil and  natural gas. His most significant political reform was to increase partici�  pation of minority parties, facilitating later challenges to the Institutional  Revolutionary Party. Most of the wealth that flowed from expanded oil  exports was squandered or pocketed by government and union officials.  His administration was discredited by the huge foreign debt it amassed  and charges of corruption.

From  the 13th and 14th centuries it was the house of the aristocracy. Until 1999  its membership included clergy, hereditary peers, life peers (peers  appointed by the prime minister since 1958), and the judges of the  Supreme Court of Judicature (Britain�s final court of appeal). Though it  predates the House of Commons and dominated it for centuries, its power  has gradually diminished. Its power to affect revenue bills was constrained  by the Parliament Act of 1911, and in 1949 its power to delay by more  than a year the enactment of any bill passed by the Commons was  revoked. In 1999 the hereditary peers lost their right to sit in the House  of Lords, though an interim reform retains their voice in a more limited  fashion.

In 1875 he refined James  Clerk Maxwell�s theory of electro�  magnetic radiation so that it  explained the reflection and refrac�  tion of light. Aiming to devise a  single theory to explain the relation�  ship of electricity, magnetism, and  light, he later suggested that atoms  might consist of charged particles  that oscillate and produce light. In  1896 his student Pieter Zeeman (1865-1943) demonstrated this phenom�  enon (see Zeeman effect), and in 1902 the two men were awarded the sec�  ond Nobel Prize for Physics. In 1904 Lorentz developed the Lorentz  transformations (including the so-called Fitzgerald-Lorentz contraction),  mathematical formulas that relate space and time measurements of one  observer to those of a second observer moving relative to the first. These  formed the basis of Albert Einstein�s special theory of relativity.</p><p>Lorentz-FitzGerald contraction or space contraction In rela�  tivity physics, the shortening of an object along the direction of its motion  relative to an observer. Dimensions in other directions are not contracted.  This concept was proposed by the Irish physicist George F. FitzGerald  (1851-1901) in 1889 and later independently developed by Hendrik  Antoon Lorentz. Significant at speeds approaching that of light, the con�  traction results from the properties of space and time, not from compres�  sion, cooling, or any similar physical disturbance. See also time dilation.</p><p>Lorentz transformations Set of equations in relativity physics that  relate the space and time coordinates of two systems moving at a constant  speed relative to each other, developed in 1904 by Hendrik Antoon  Lorentz. Required to describe phenomena approaching the speed of light,  these transformations express the concepts that space and time are not  absolute; that length, time, and mass depend on the observer�s relative  motion; and that the speed of light in a vacuum is constant and indepen�  dent of the motion of the observer or the source.</p><p>Lorenz, Edward (Norton) (b. May 23, 1917, West Hartford, Conn.,  U.S.) U.S. meteorologist. Following degrees from Dartmouth College and  Harvard University in mathematics, he turned to weather forecasting in  1942 with the U.S. Army Air Corps. After World War II he joined MIT  as a researcher, earned a doctorate in meteorology (1948), and stayed on  as a professor. In the early 1960s, he discovered that the weather exhibits  a nonlinear phenomenon known as sensitive dependence on initial con�  ditions (see chaos theory). He explained this phenomenon, which makes  long-range weather forecasting impossible, to the public as the �butterfly  effect�: in China a butterfly flaps its wings, leading to unpredictable  changes in U.S. weather a few days later.</p><p>Lorenz \'lor-ents\, Konrad (Zacharias) (b.

In 1935 he first elucidated and demonstrated  the phenomenon of imprinting in ducklings and goslings. He later exam�  ined the roots of human aggression (in the best-selling On Aggression,  1963) and the nature of human thought.

Both broth�  ers were possibly pupils of Duccio di Buoninsegna, whose influence is  seen in Pietro�s altarpiece in the Pieve di Santa Maria at Arezzo and in  Ambrogio�s early works. Ambrogio�s works reveal an individualistic real�  ism and preoccupation with three-dimensional space and form, most evi�</p><p>dent in his fresco series in Siena�s Palazzo Pubblico (1338-39). These  most important of Sienese frescoes reveal him to be an explorer of per�  spective and a political and moral philosopher. Pietro�s dramatic frescoes  in the lower church of San Francesco at Assisi (c. 1315) show his rela�  tion to the art of Giotto, though he departs from Giotto in his attention  to detail. His Birth of the Virgin and Ambrogio�s Presentation in the  Temple, for Siena Cathedral (1342), are notable for their handling of per�  spective.

His work combined the graceful lines and decorative feeling of the  Sienese school with the traditions of the Florentine school. His Corona�  tion of the Virgin (1413) reveals his predilection for swirling draperies  and rhythmic, curvilinear forms and his understanding of light.

Among his recurring motifs are love,  death, and despair at the passing of sensuous life. He reveals his com�  passion in such works as The Book of Pity and of Death (1890). His  themes anticipated some of the preoccupations of French literature  between the world wars.</p><p>lottery Drawing of lots in which prizes are distributed to the winners  among persons buying a chance. A form of gambling, lottery in its mod�  em form may be traced to 15th-century Europe. The Continental Con�  gress in 1776 voted to establish a lottery to raise funds for the American  Revolution. By the mid-19th century, in the wake of abuses by private  organizers, U.S. states began passing antilottery laws. An 1878 Supreme  Court opinion held that lotteries had �a demoralizing influence upon the  people,� and by the 1890s most had been eliminated. A revival began in  the mid-1960s; many state governments seeking revenues instituted offi�  cially sanctioned, independently audited lotteries. In most such opera�  tions, the bettor buys a numbered receipt or writes down his or her number  choices, a drawing is held, and the winners identify themselves. The value  of the prizes is the amount remaining after expenses and the state�s share  are deducted from the pool. Winnings are usually subject to taxes. The  top prize can grow into the tens of millions, usually causing a buying  frenzy as it increases, but the odds against winning remain astronomical.</p><p>Lotto, Lorenzo (b. c. 1480, Venice�d. 1556, Loreto, Papal States)  Italian painter.

The lotus of the Greeks is Ziziphus  lotus (family Rhamnaceae), a shrub native to southern Europe; wine made  from its fruit was thought to produce contentment and forgetfulness. The  Egyptian lotus is a white water uly ( Nymphaea lotus). The sacred lotus of  the Hindus is an aquatic plant (Nelumbo nucifera ) with white or delicate  pink flowers; the lotus of eastern North America is Nelumbo pentapetala,  a similar plant with yellow blossoms. Lotus is also a genus of the pea  family (see legume), containing about 100 species found in temperate  regions of Europe, Asia, Africa, and North America; the 20 or more spe�  cies in North America are grazed by animals. The lotus is a common  ornament in architecture, and since ancient times it has symbolized fer�  tility, purity, sexuality, birth, and rebirth of the dead.</p><p>Lotus Sutra Text central to the Japanese Tendai (Chinese Tiantai) and  Nichiren sects of Mahayana Buddhism.

The son of  Charlemagne, he was crowned coemperor with his father in 813 and  became emperor in 814 on his father�s death. As emperor, Louis imple�  mented important religious and cultural reforms and formalized Carolin-  gian relations with the pope. He also introduced a plan of succession that  sought to preserve the integrity of the empire while respecting the Ger�  manic tradition of dividing the realm among all heirs. The birth of the  future Charles II (Charles the Bald) to his second wife, Judith, and alter�  ation of the plan of succession provided Louis�s older sons and a number  of bishops with an excuse for rebellion. Twice deposed by his sons, he  recovered the throne each time (830, 834), but at his death his surviving  sons indulged in a bloody civil war that left the Carolingian empire in  disarray.</p><p>Louis I or Ludwig Vliit-vik\ I (b.

The son of Maximilian II of  Bavaria, he supported Prussia in the Franco-Prussian War (1870-71). He  brought his territories into the newly founded German Empire in 1871  but concerned himself only intermittently with affairs of state, preferring  a life of increasingly morbid seclusion. A lifelong patron of the composer  Richard Wagner, he developed a mania for extravagant building projects;  the most fantastic, Neuschwanstein, was a fairy-tale castle decorated with  scenes from Wagner�s operas. He drowned himself three days after he  was formally declared insane.</p><p>Louis IV or Ludwig IV known as Louis the Bavarian (b. 1283,  Munich, Ger.�d.

As the Luxembourg candi�  date for emperor, he was opposed by the Habsburg candidate Frederick  III of Austria. Both men were elected and crowned king in 1314, and  Louis�s forces defeated Frederick�s army in 1322. A conflict with Pope  John XXII over the appointment of the imperial vicar in Italy led to his  excommunication (1324). To placate his opponents, Louis agreed to rule  jointly with Frederick, an arrangement that continued until Frederick�s  death (1330). He accepted the imperial crown from the Roman people  instead of from the pope (1328) and backed the appointment of an anti�  pope. In 1346 Pope Clement VI secured the election of a rival king, Charles  of Moravia, and Louis died of a heart attack before finishing his prepa�  rations for war.</p><p>Louis VI known as Louis the Fat (b. 1081�d.

Doubtful of her fidelity, he had the marriage annulled  in 1152 and, after the death of his second wife, married Alix of Cham�  pagne, who bore him his son and heir, Philip II Augustus. Eleanor married  the future Henry II of England, who took control of Aquitaine and carried  on a long rivalry with Louis (1152-74) marked by recurrent warfare and  constant intrigue. Louis was joined by Conrad III in leading the Second  Crusade (1147-49), which failed in all its objectives.</p><p>Louis IX or St. Louis (b. April 25, 1214, Poissy, France�d. Aug. 25,  1279, near Tunis, Tun.; canonized Aug. 11, 1297; feast day August 25)  King of France (1226-70). He inherited the throne at age 12. His mother  served as regent until 1234, helping to subdue rebellious barons and Albi-  gensian heretics (see Cathari). Louis led a Crusade (1248-50) in hopes of  regaining Jerusalem and Damascus, but his troops were badly defeated by  the Egyptians. On his return he reorganized the royal administrative sys�  tem and standardized coinage. He built the extraordinary Sainte-Chapelle  to house a religious relic believed to be Jesus� crown of thorns. Louis  made peace with the English in the Treaty of Paris (1259), allowing Henry  III to keep Aquitaine and neighboring lands but obliging him to declare  himself Louis�s vassal. He died of plague during a Crusade. The most  popular of the Capetian kings, his reputation for justness and piety led the  French to venerate him as a saint even before his canonization in 1297.</p><p>Louis XI (b. July 3, 1423, Bourges, France�d. Aug. 30, 1483, Plessis-  les-Tours) King of France (1461-83). He plotted against his father,  Charles VII, and was exiled to Dauphine (1445), which he ruled as a sov�  ereign state until Charles approached its borders with an army (1456).  Louis then fled to the Netherlands, returning to France to become king  on his father�s death in 1461. He fought rebellious French princes (1465)  and made concessions to Charles the Bold (1468). Seeking to strengthen  and unify France, he destroyed the power of the Burgundians in 1477. He  regained control of Boulonnais, Picardy, and Burgundy, took possession  of Franche-Comte and Artois (1482), annexed Anjou (1471), and inher�  ited Maine and Provence (1481).</p><p>Louis XII (b. June 27, 1462, Blois, France�d. Jan. 1, 1515, Paris) King  of France (1498-1515). He became king on the death of his cousin Charles  VIII. He annulled his marriage to marry Charles�s widow, Anne of Britt�  any, and to reinforce the union of her duchy with France. He continued  France�s part in the Italian Wars, often with disastrous results. He con�  quered Milan in 1499, then lost it, but was later recognized as duke of  Milan by Emperor Maximilian 1. He concluded a treaty with Ferdinand V  that partitioned Naples (1500), but the two kings went to war and Louis  lost all of Naples (1504). In 1508 he consolidated the League of Cambrai,  but when the league fell apart in 1510 its members joined England in a  Holy League against France, invading it several times. Despite his fail�  ures, Louis was highly popular with the French, who called him the  �Father of the People.�</p><p>Louis XIII (b. Sept. 27, 1601, Fontainebleau, France�d. May 14, 1643,  Saint-Germain-en-Laye) King of France (1610�43). He was the son of  Henry IV and Marie de Medicis. His mother was regent until 1614 but  continued to govern until 1617; she arranged Louis�s marriage to the  Spanish Anne of Austria in 1615. Resentful of his mother�s power, Louis  exiled her, but Cardinal de Richelieu, her principal adviser, reconciled them  in 1620. In 1624 Louis made Richelieu his principal minister, and the two  cooperated closely to make France a leading European power, consoli�  dating royal authority in France and fighting to break the dominant rule  of the Spanish and Austrian Habsburgs in the Thirty Years' War. Pro-  Spanish Catholic zealots led by Marie de Medicis appealed to Louis to  reject Richelieu�s policy of supporting the Protestant states, but Louis  stood by his minister and his mother withdrew into exile. France declared  war on Spain in 1635 and had won substantial victories by the time Rich�  elieu died in 1642. Louis was succeeded by his son Louis XIV.</p><p>Louis XIII style Style of the visual arts produced in France during the  reign of Louis XIII, including the regency of his mother, Marie de Medicis,  who introduced much of the art of her native Italy. The Mannerism of Italy  and Flanders was so influential that a true French style did not develop  until the mid-17th century, when the influence of Caravaggio was assimi�  lated by Georges de La Tour and the Le Nain brothers, and the influence of</p><p>the Carracci brothers was extended by Simon Vouet, who trained the aca�  demic painters of the next generation. The sculpture of the period was  undistinguished. The most prolific area of the arts was architecture. Here,  too, the Italian influence is seen, as in the Palais de Justice at Rennes and  the Luxembourg Palace in Paris, both designed by Salomon de Brosse,  and the chapel of the Sorbonne in Paris, designed by Jacques Lemercier.  The furniture of the period is typically massive and solidly built and com�  monly decorated with cherubs, ornate scrollwork, fruit-and-flower swags,  and grotesque masks.</p><p>Louis XIV known as the Sun King (b. Sept. 5, 1638, Saint-Germain-  en-Laye, France�d. Sept. 1, 1715, Versailles) King of France (1643�  1715), ruler during one of France�s most brilliant periods and the symbol  of absolute monarchy of the Neoclassical age. He succeeded his father,  Louis XIII, at age four, under the regency of his mother, Anne of Austria.  In 1648 the nobles and the Paris Parlement, who hated the prime minis�  ter, Cardinal Mazarin, rose against the crown and started the Fronde. In  1653, victorious over the rebels, Mazarin gained absolute power, though  the king was of age. In 1660 Louis married Marie-Therese of Austria  (1638-83), daughter of Philip IV of Spain. When Mazarin died in 1661,  Louis astonished his ministers by informing them that he intended to  assume responsibility for ruling the kingdom. A believer in dictatorship  by divine right, he viewed himself as God�s representative on earth. He  was assisted by his able ministers, Jean-Baptiste Colbert and the marquis  de Louvois. Louis weakened the nobles� power by making them depen�  dent on the crown. A patron of the arts, he protected writers and devoted  himself to building splendid palaces, including the extravagant Versailles,  where he kept most of the nobility under his watchful eye. In 1667 he  invaded the Spanish Netherlands in the War of Devolution (1667-68) and  again in 1672 in the Third Dutch War. The Sun King was at his zenith;  he had extended France�s northern and eastern borders and was adored  at his court. In 1680 a scandal involving his mistress, the marchioness de  Montespan (1641-1707), made him fearful for his reputation, and he  openly renounced pleasure. The queen died in 1683, and he secretly mar�  ried the pious marchioness de Maintenon. After trying to convert French  Protestants by force, he revoked the Edict of Nantes in 1685. Fear of his  expansionism led to alliances against France during the War of the Grand  Alliance (1688-97) and the War of the Spanish Succession (1701-14).  Louis died at age 77 at the end of the longest reign in European history.</p><p>Louis XIV style Style of the visual arts produced in France during the  reign of Louis XIV. In 1648 Charles Le Brun founded the Royal Academy  of Painting and Sculpture, which rigidly dictated styles for the rest of the  reign. The most influential painter was Nicolas Poussin, who forged the  way for French Classicism (see Classicism and Neoclassicism). Sculpture  reached a new zenith with the works of Francois Girardon and Pierre Puget.  A national style in the decorative arts evolved through the Gobelin fac�  tory (see Gobelin family). Furniture was veneered, inlaid, heavily gilded,  and commonly decorated with shells, satyrs, garlands, mythological  heroes, and dolphins; the style is particularly associated with Andre-  Charles Boulle. In architecture, Jean-Baptiste Colbert rigidly controlled the  renovation of the Palace of Versailles, with landscaping by Andre Le Notre.</p><p>Louis XV (b. Feb. 15, 1710, Versailles, France�d. May 10, 1774, Ver�  sailles) King of France (1715-74). An orphan from age three, Louis suc�  ceeded to the throne on the death of his great-grandfather Louis XIV (1715),  under the regency of Philippe II, duke d�Orleans (1674-1723). His mar�  riage to Princess Marie Leszczynska of Poland (1703-68) in 1725 led to  France�s involvement in the War of the Polish Succession (1733-38). He  chose Andre-Hercule de Fleury as his chief minister in 1726, and his own  influence became perceptible only after Fleury�s death in 1744. Louis�s  mistresses, particularly the marchioness de Pompadour, held considerable  political influence. Louis brought France into the War of the Austrian Suc�  cession (1740^-8) and the Seven Years' War (1756-63), by which France  lost to Britain almost all its colonial possessions. As the crown�s moral  and political authority declined, the Parlements gained in power, prevent�  ing fiscal reform.

Jan. 21, 1793, Paris)  Last king of France (1774-92) in the Bourbon line preceding the French  Revolution. In 1770 he married Marie-Antoinette, and in 1774 he suc�  ceeded to the throne on the death of his grandfather, Louis XV. Immature  and lacking in strength of character, he was unable to give the necessary  support to his ministers, including Anne-Robert-Jacques Turgot and  Jacques Necker, in their efforts to stabilize France�s tottering finances.  Restoration of the Parlements in 1774 shifted power to the aristocracy.  Aristocratic opposition to the economic reforms of Charles-Alexandre de  Calonne forced the king to summon the Estates-General in 1788, setting  the Revolution in motion. Dominated by the reactionary court faction, he  defended the privileges of the clergy and nobility. He dismissed Necker  in 1789 and refused to sanction the achievements of the National Assem�  bly. His resistance to popular demands was one cause for the royal fami�  ly�s forcible transfer from Versailles to the Tuileries palace in Paris. He  lost credibility further when he attempted to escape the capital in 1791  and was caught at Varennes and returned to Paris. Thereafter he was  dominated by the queen, who encouraged him to a policy of subterfuge  instead of implementing the Constitution of 1791, which he had sworn  to maintain. In 1792 the Tuileries was captured by the people and mili�  tia, and the First French Republic was proclaimed. When proof of his  counterrevolutionary intrigues with foreigners was found, he was tried for  treason. Condemned to death, he went to the guillotine in 1793. His dig�  nity during his trial and execution only somewhat redeemed his reputa�  tion.</p><p>Louis XVI style Style of the visual arts produced in France from c.  1760 to the French Revolution. The predominant style in painting, archi�  tecture, sculpture, and the decorative arts was Neoclassicism�a reaction  against the excesses of the Rococo style and a response to Jean-Jacques  Rousseau�s call for �natural� virtue, as well as a response to the excava�  tions at Pompeii and Herculaneum. The most prominent painter was Jacques-  Louis David, whose severe compositions recalled the style of Nicolas  Poussin. The foremost sculptor of the day was Jean-Antoine Houdon. The  style in furniture was classical, yet workmanship was more complex than  in any earlier period. Jean-Henri Riesener and other German craftsmen were  among the most prominent cabinetmakers.

In 1792 he was imprisoned with the rest of the royal family. When his  father was beheaded in 1793, the French emigre nobility proclaimed Louis-  Charles king. He died in prison at age 10, but the secrecy surrounding his  last months gave rise to rumours that he was not dead, and over the next  few decades more than 30 persons claimed to be Louis XVII.

He fled the  country in 1791, during the French Revolution, and issued counterrevo�  lutionary manifestos and organized emigre-nobility associations. He became  regent for his nephew Louis XVII after the 1793 execution of Louis XVI, and  at the dauphin�s death in 1795 he proclaimed himself king. When the  allied armies entered Paris in 1814, Charles-Maurice de Talleyrand negoti�  ated the Bourbon Restoration and Louis was received with jubilation. He  promised a constitutional monarchy, and the Charter of 1814 was  adopted; after the interruption of the Hundred Days, when Napoleon  returned from Elba, he resumed his constitutional monarchy. The legis�  lature included a strong right-wing majority, and though Louis opposed  the extremism of the ultras, they exercised increasing control and thwarted  his attempts to heal the wounds left by the Revolution. He was succeeded  at his death by his brother, Charles X.</p><p>Louis, Joe in full Joseph Louis Barrow (b. May 13, 1914, Lafay�  ette, Ala., U.S.�d. April 12, 1981, Las Vegas, Nev.) U.S. boxer.

Nicknamed �the Brown Bomber,� Louis gained the world heavy�  weight championship by defeating Braddock in 1937 and held the title  until 1949. Two of Louis�s most famous bouts, those with the German  boxer Max Schmeling, were invested with nationalist and racial implica�  tions, as Schmeling was seen, unfairly, as the embodiment of Aryanism  and the Nazi party. Louis lost to Schmeling in 1936 but defeated him in  one round in 1938, causing much jubilation among Americans, and espe�  cially African Americans. He successfully defended his title 25 times (21  by knockout) before retiring in 1949. His service in the U.S. Army dur�  ing World War II no doubt prevented him from defending his title many  more times. He made unsuccessful comeback attempts against Ezzard  Charles in 1950 and Rocky Marciano in 1951.</p><p>Louis, Morris orig. Morris Louis Bernstein (b. Nov. 24, 1912,  Baltimore, Md., U.S.�d.

Inspired by Helen Frankenthaler�s  colour stain technique, in 1954 he began a series of paintings titled Veils,  featuring stained vertical waves of colour; these works had an impersonal,  nonpainterly quality. During this period he became associated with the  New York school of Abstract Expressionism.

Eldest son of the duke d� Orleans, he supported the new gov�  ernment at the outbreak of the French Revolution and joined the Revo�  lutionary army in 1792 but deserted during the war with Austria (1793)  and lived in exile in Switzerland, the U.S., and England. He returned to  France on the restoration of Louis XVIII and joined the liberal opposition.  Following the July Revolution (1830) and Charles X�s abdication, he was  proclaimed the �Citizen King� by Adolphe Thiers and elected by the leg�  islature. During the subsequent July Monarchy, he consolidated his power  by steering a middle course between the right-wing monarchists and the  socialists and other republicans but resorted to repressive measures  because of numerous rebellions and attempts on his life. He strengthened  France�s position in Europe and cooperated with the British in forcing the  Dutch to recognize Belgian independence. Mounting middle-class oppo�  sition to his arbritrary rule and his inability to win allegiance from the  new industrial classes caused his abdication during the February Revolu�  tion of 1848.</p><p>Louis the Bavarian See Louis IV  Louis the Fat See Louis VI  Louis the Pious See Louis I  Louis the Younger See Louis VII</p><p>Louisiade \lu-,e-ze-'ad\ Archipelago Island group, Papua New  Guinea, southeast of New Guinea.

The  city of New Orleans was founded in 1718, and Louisiana became a French  crown colony in 1731. Colonization increased in the 1760s with the arrival  of French-speaking Acadians (Cajuns) from Nova Scotia. Spain controlled  the territory from 1762 to 1800; then it passed back to the French.

Louisiana became the 18th U.S. state in 1812. It seceded from the Union in  1861 at the start of the American Civil War and was readmitted in 1868. The  plantation economy continued with the farmer class denied land owner�  ship, which contributed to the rise of the populist Huey Long in the 1920s.  After World War II Louisiana experienced more rapid development with  the rise of offshore oil and gas drilling. Soybeans are a major agricultural  crop; tree farming and shrimp fishing are also important. Petroleum and  natural gas are the chief mineral resources. In 2005 hurricanes devastated  New Orleans and surrounding communities.</p><p>Louisiana Purchase Territory purchased by the U.S. from France in  1803 for $15 million. It extended from the Mississippi River to the Rocky  Mountains and from the Gulf of Mexico to British America (Canada). In  1762 France had ceded Louisiana west of the Mississippi River to Spain,  but Spain returned it to French control in 1800. Alarmed by this poten�  tial increase in French power. Pres. Thomas Jefferson threatened to form  an alliance with Britain. Napoleon then sold the U.S. the entire Louisi�  ana Territory, although its boundaries remained unclear; its northwestern  and southwestern limits were not established until 1818-19. The purchase  doubled the area of the U.S.</p><p>Louisville Vlu-i-,vil\ City (pop., 2000: 256,231), north-central Kentucky,  U.S., located on the Ohio River. Settled in 1778 on Corn Island, it  expanded the next year when the settlers moved ashore. Named for Louis  XVI of France, it became an important river trading centre and was char�  tered as a city in 1828. During the American Civil War it served as a Union  military headquarters and supply depot. The largest city in Kentucky, it  is a leading producer of bonded bourbon whiskey and cigarettes. It is  home to the University of Louisville (founded 1798) and Churchill  Downs, the site of the Kentucky Derby.</p><p>Loup \Tiip\ River River, east-central Nebraska, U.S. It flows east to join  the Platte River. It is 300 mi (485 km) long and is harnessed to produce  hydroelectric power. Its name is derived from the French name (meaning  �wolf�) for the Skidi Indians.</p><p>Lourdes Pilgrimage site in southwestern France, situated southwest of  Toulouse at the foot of the Pyrenees. The town and its fortress formed a  strategic stronghold in medieval times, but its modern significance dates  from 1858, when a 14-year-old girl had repeated visions of the Virgin  Mary (see Bernadette of Lourdes). The visions were declared authentic by  Pope Pius IX in 1862. The underground spring in the grotto where Berna�  dette had her visions was declared to have miraculous qualities, and Lour�  des has since become one of the foremost destinations for Roman Catholic  pilgrims. Nearly 3 million visit annually, many of them sick or disabled  people hoping to be healed. A basilica was built above the grotto in 1876,  and a vast underground church was added in 1958.</p><p>Lourenco Marques See Maputo</p><p>louse Any of some 3,300 species of small, wingless, parasitic insects of  the order Phthiraptera. The order consists mainly of biting, or chewing,  lice (parasites of birds and mam�  mals) and sucking lice (see sucking  louse). The louse�s body is flattened.</p><p>The eggs, or nits, are cemented to the  hair or plumage of the host, and most  species spend their entire lives on the  bodies of host animals. Heavy infes�  tations cause much irritation and  may lead to secondary infections. In  moving from host to host, lice may  spread many diseases, including  tapeworm infestation in dogs and  murine typhus in rats.</p><p>louse, human Any of three types  of sucking louse that infest humans.</p><p>The body louse (mainly Pediculus  humanus humanus, also called  human louse or cootie) and head  louse (P. h. capitis) are spread by  person-to-person contact and  through shared clothing, bedding,  combs, and other personal items.</p><p>Body lice carry the organisms that cause relapsing fever, trench fever, and  typhus. Head lice may cause impetigo. Both are readily spread under con�  ditions of overcrowding, especially among children. The crab louse, or  pubic louse ( Phthirus pubis ) infests primarily the pubic region and occa�  sionally other hairy regions. Its first pair of legs is smaller than the other  two pairs, making it look like a crab. Crab lice are transmitted primarily  through sexual intercourse. Lice infestations can be quickly cured with  shampoos, soaps, and lotions containing benzene hexachloride, along with  the thorough washing of bedding and clothing.</p><p>lousewort Any of about 500 species of herbaceous plants that make  up the genus Pedicularis in the snap�  dragon family. The lousewort is  found throughout the Northern  Hemisphere but especially on the  mountains of central and eastern  Asia. The bilaterally symmetrical  flowers sometimes have very  unusual shapes. The flowers of the  little elephant (P. groenlandica), for  example, resemble the head, trunk,  and ears of an elephant. Louseworts  are semiparasitic on the roots of  other plants.</p><p>Louvain \lu-'va n \, Catholic Uni�  versity of Either of two Belgian  universities established in 1970, both  descended from a renowned univer�  sity founded in 1425 in Louvain. The  original university included on its  faculty in the early 1500s Desiderius  Erasmus, Justus Lipsius, and Gerar�  dus Mercator. The modern university was reorganized into separate units  following student riots and government upheavals in 1969. At the Katho-  lieke Universiteit te Leuven, the language of instruction is Dutch.

The son of Michel Le Tellier (1603-85),  one of the most powerful officials in France, he was groomed by his father  to replace him as war secretary. A brilliant administrator, Louvois brought  his father�s military reforms to fruition, making the French army one of  the most formidable in Europe. He was complicit in the military policy  that led up to the revocation of the Edict of Nantes (1685), and was also  responsible for the destruction of the Palatinate (1688), which led to the  War of the Grand Alliance.</p><p>Louvre VliivrA Museum National museum and art gallery of France,  in Paris. It was built as a royal residence, begun under Francis I in 1546  on the site of a 12th-century fortress. It ceased to be used as a palace  when the court moved to Versailles in 1682, and plans were made in the  18th century to turn it into a public museum. In 1793 the revolutionary  government opened the Grand Gallery; Napoleon built the northern wing;  and two major western wings were completed and opened by Napoleon  III. The completed Louvre included a vast complex of buildings forming  two main quadrilaterals and enclosing two large courtyards. A controver�  sial steel-and-glass pyramid entrance designed by I.M. Pei opened in 1989.  The painting collection is one of the richest in the world, representing all  periods of European art up to Impressionism; its collection of French 15th�  19th-century paintings is unsurpassed.</p><p>lovage \'b-vij\ Herb ( Levisticum officinale ) of the parsley family, native  to southern Europe. It is cultivated for its stalks and foliage, which are  used for tea, as a vegetable, and to flavour foods. Its rhizomes are used as  a carminative, and the seeds are used for flavouring desserts.

In 1835  she married William King, 8th Baron King; when he was created an earl  in 1838, she became countess of Lovelace. Having studied with the  famous mathematician-logician Augustus De Morgan, she was introduced  to Charles Babbage�s Difference Engine (calculator) and studied plans for  his Analytical Engine (computer) as early as 1833. In 1843 she translated  and annotated an article about the Analytical Engine by Italian mathema�  tician Luigi Federico Menabrea. In correspondence with Babbage, she  also described how the Analytical Engine could be �programmed� to cal�  culate certain numbers; this work has been called the first computer pro�  gram, and in consequence she has been called the first computer  programmer. Ada, a computer programming language, is named for her.</p><p>Lovell Vta-volV Sir (Alfred Charles) Bernard (b. Aug. 31, 1913,  Oldland Common, Gloucestershire, Eng.) British radio astronomer.

It was renamed for industrial�</p><p>ist Francis Lowell and was incorporated as a town in 1826. In the 20th  century it began losing textile manufacturing to southern states, and it  diversified into other industries.

Born into the prominent Lowell  family of Boston, she devoted herself to poetry at age 28 but published  nothing until 1910. Her first volume, A Dome of Many-Coloured Glass  (1912), was succeeded by Sword Blades and Poppy Seed (1914), which  included her first poems in free verse and what she called �polyphonic  prose.� She became a leader of Imagism and was noted for her vivid and  powerful personality and her scorn of conventional behaviour. Her other  works include Six French Poets (1915), Tendencies in Modern American  Poetry (1917), and John Keats, 2 vol. (1925).</p><p>Lowell, Francis Cabot (b.

Born into a promi�  nent Massachusetts family, Lowell closely studied the British textile  industry while visiting Britain. With Paul Moody he devised an efficient  power loom and spinning apparatus. His Boston Manufacturing Co. in  Waltham (1812-14) was apparently the world�s first mill in which were  performed all operations converting raw cotton into finished cloth. His  example greatly stimulated the growth of New England industry. Lowell,  Mass., is named for him.</p><p>Lowell, James Russell (b. Feb. 22, 1819, Cambridge, Mass.,  U.S.�d.

In  the 1840s he wrote extensively  against slavery, including the Biglow  Papers (1848), satirical verses in  Yankee dialect. His other most  important works are The Vision of Sir  Launfal (1848), a long poem on the  brotherhood of mankind; and A  Fable for Critics (1848), a witty  evaluation of contemporary authors.</p><p>After his wife�s death in 1853, he  wrote mainly essays on literature,  history, and politics.

In the 1890s he built a private observatory in  Flagstaff, Ariz., to study Mars. He championed the now-abandoned theory  that intelligent inhabitants of a dying Mars had constructed a planetwide  system of irrigation. He thought that the so-called canals of Mars (see  Mars, canals of) were bands of cultivated vegetation dependent on this  irrigation. Lowell�s theory, long vigorously opposed, was finally put to  rest by images received from the U.S. Mariner spacecraft. His prediction  of a planet beyond Neptune was vindicated when Pluto was discovered  in 1930.</p><p>Lowell, Robert orig. Robert Traill Spence Lowell, Jr. (b. March  1, 1917, Boston, Mass., U.S.�d.

Though he turned away from his  Puritan heritage, it forms the subject of much of his poetry. His first major  work, Lord Weary�s Castle (1946, Pulitzer Prize), contains �The Quaker  Graveyard in Nantucket.� Life Studies (1959) contains an autobiographi�  cal essay and 15 complex, confessional poems largely based on his fam�  ily history and personal life, which included time in mental institutions.

In his youth Lowry rebelled against his conven�  tional upbringing and shipped to China as a cabin boy; he later lived in  France, the U.S., Mexico, Canada, and Italy. His reputation rests on the  novel Under the Volcano (1947), about the last desperate day of a dispir�  ited alcoholic and former British consul in Mexico. Its juxtaposition of  images of social decay and self-destructiveness was seen as a symbolic  vision of Europe on the verge of World War II. Though critically praised,  it received popular recognition only after Lowry�s death at age 47, prob�  ably the result of alcoholism.</p><p>Loy, Myrna orig. Myrna Williams (b.

She  played bit parts in Hollywood movies before being cast as the exotic mis�  tress in the 1925 production of Ben-Hur, which established her early film  persona as a foreign vamp. She earned praise as the wittily sophisticated  Nora Charles in The Thin Man (1934) and its sequels and in other movies  such as The Best Years of Our Lives (1946), Mr. Blandings Builds His  Dream House (1948), Cheaper by the Dozen (1950), and Lonely hearts  (1958). Dubbed the �Queen of Hollywood� during her heyday, she evinced  equality in a male-dominated world, and her combination of beauty and  brains made male audiences regard her as the ideal mate. She worked for  the American Red Cross in World War II and later for UNESCO.</p><p>loyalist American colonist loyal to Britain in the American Revolution.  About one-third of American colonists were loyalists, including office�  holders who served the British crown, large landholders, wealthy mer�  chants, Anglican clergy and their parishioners, and Quakers. Loyalists  were most numerous in the South, New York, and Pennsylvania, but they  did not constitute a majority in any colony. At first they urged modera�  tion in the struggle for colonial rights; when denounced by radical patri�  ots, they became active partisans. Some joined the British army, including  23,000 from New York; when captured in battle, they were treated as trai�  tors. All states passed laws against them, confiscating or heavily taxing  their property. Beginning in 1776, about 100,000 loyalists fled into exile,  many to Canada. Public sentiment against them diminished after 1789,  and punitive state laws were repealed by 1814.</p><p>Loyola, Saint Ignatius of orig. Inigo de Onaz y Loyola (b.</p><p>1491, Loyola, Castile�d.

While convalesc�  ing from wounds inflicted by a French cannonball in 1521, he experienced  a religious conversion. After a pilgrimage to Jerusalem, he pursued reli�  gious studies in Spain and France. In Paris he gathered about him the  companions (including St. Francis Xavier) who were to join him in found�  ing the Jesuits. He was ordained a priest in 1537 and established the Soci�  ety of Jesus in 1539. The new order received papal approval in 1540, and  Loyola served as its general until his death, by which time it had branches  in Italy, Spain, Germany, France, Portugal, India, and Brazil. Loyola  described his mystical vision of prayer in The Spiritual Exercises. In his  last years he laid the foundations of a system of Jesuit schools.</p><p>Lozi \'lo-ze\ or Barotse \bo-'rat-s9\ Complex of 25 Bantu-speaking  peoples divided into six cultural groups centring on the area formerly  known as Barotseland in western Zambia.

He moved to Hollywood in 1923 and  developed a style of sophisticated wit and unerring narrative timing �the  famous �Lubitsch touch��in successful comedies such as The Marriage  Circle (1924), The Love Parade (1929), Trouble in Paradise (1932),  Ninotchka (1939), The Shop Around the Corner (1940), To Be or Not to  Be (1942), and Heaven Can Wait (1943).</p><p>Lublin \'lu-blin\ City (pop., 2000 est.: 355,803), eastern Poland, situated  on the Bystrzyca River. Founded as a stronghold in the late 9th century,  the settlement received town rights in 1317. In 1795 it passed to Austria  and in 1815 to Russia. In 1918 the first independent temporary Polish  government was proclaimed in Lublin. In World War II the Nazi concen�  tration camp Majdanek was established in one of its suburbs. After the  war Lublin served briefly as the seat of the national government. It is now  an industrial and cultural centre for southeastern Poland.</p><p>lubrication Introduction of any of various substances between sliding  surfaces to reduce wear and friction. Lubricants may secondarily control  corrosion, regulate temperature, electrically insulate, remove contami�  nants, or damp shock. Prehistoric peoples used mud and reeds to lubri�  cate sledges, timbers, or rocks. Animal fat lubricated the axles of the first  wagons and continued in wide use until crude oil became the chief source  of lubricants. Crude oil has been the basis of products designed for the  specific lubricating needs of automobiles, aircraft, locomotives, turbojets,  and all other power machinery. There are three basic varieties of lubri�  cation: fluid-film (in which a fluid film completely separates sliding sur�  faces), boundary (in which the friction between surfaces is determined by  the properties of the surfaces and properties of the lubricant other than  viscosity), and solid (used when liquid lubricants lack adequate resistance  to load or temperature extremes). The principal lubricants are liquid, oily  materials (petroleum-based or synthetic, and including greases); solids  (such as graphite, molybdenum disulfide, soft metals, waxes, and plas�  tics); and gases.</p><p>Lubumbashi V.lii-biim-'ba-sh e\ formerly (until 1966) Elisabethville  City (pop., 1994 est.: 851,381), Democratic Republic of the Congo. It was  established by Belgian colonists in 1910 near the border with Zambia and  grew to become the centre of one of the world�s largest copper mining  and smelting operations. It was the centre of Katanga province�s seces�  sion movement in the early 1960s.</p><p>Luca da Cortona See Luca Signorelli</p><p>Lucas, George (b.

His first feature film, THX 1138 (1971), was followed by the  surprise success American Graffiti (1973). He wrote and directed the  immensely popular science-fiction movie Star Wars (1977), which made  innovative use of computerized special effects. He formed the production  company Lucasfilms (1978) and its special-effects division Industrial  Light and Magic and produced the Star Wars sequels �The Empire Strikes  Back (1980) and The Return of the Jedi (1993)�as well as Steven Spiel�  berg�s Raiders of the Lost Ark (1981) and its sequels. He returned to  directing with the first Star Wars prequel, The Phantom Menace (1999),  which was followed by the other prequels Attack of the Clones (2002)  and Revenge of the Sith (2005).</p><p>Lucas, Robert E., Jr. (b. Sept. 15, 1937, Yakima, Wash., U.S.) U.S.  economist. He studied at the University of Chicago and began teaching  there in 1975. He questioned the influence of John Maynard Keynes in  macroeconomics and the efficacy of government intervention in domestic  affairs. He criticized the Phillips curve for failing to provide for the damp�  ened expectations of companies and workers in an inflationary economy.  His theory of rational expectations, which suggests that individuals may  alter the expected results of national fiscal policy by making private eco�  nomic decisions based on anticipated results, won him the 1995 Nobel  Prize.

He was trained by his father, a painter, but his great talent  was as an engraver. Even such youthful prints as Muhammad and the  Monk Sergius (1508) show great technical skill. In 1510, under the influ�  ence of Albrecht Durer, he produced two masterpieces of engraving, The  Milkmaid and Ecce Homo, the latter much admired by Rembrandt. He is  thought to have developed the technique of etching on copper (instead of  iron) plates; the softness of copper permitted him to combine etching and  line engraving in the same print. He was also among the first to employ  aerial perspective in prints. Though his paintings seldom attain the power  of his engravings, he was an outstanding Netherlandish painter of his  period; The Last Judgment (1526-27) is his most celebrated painting.</p><p>Luce, Clare Boothe orig.

As a young man he acquired a Greek literary  education while traveling through western Asia Minor. He became a pub�  lic speaker before turning to writing essays. His works, outstanding for  their mordant wit, are a sophisticated critique of the shams and follies of  the literature, philosophy, and intellectual life of his day. In such works  as Charon, Dialogues of the Dead, True History, and Nigrinus, he sati�  rized nearly every aspect of human behaviour. His best work of literary  criticism is How to Write History.</p><p>Luciano Hu-'cha-noV Lucky orig. Salvatore Lucania later  Charles Luciano (b. Nov. 11, 1896, Lercara Friddi, Sicily, Italy�d.

In 1916 he conspired with Frank Costello, Meyer Lansky, and  other young gangsters, earning the nickname �Lucky� by evading arrest  and winning at craps. He joined the crime gang of Joe Masseria in 1920  and was soon directing Masseria�s bootlegging, narcotics, and prostitu�  tion rackets. In 1931 he had both Masseria and rival boss Salvatore Maran-  zano murdered; by 1934 he was �boss of all bosses� in a national crime  syndicate. Jailed for extortion in 1936, he continued to direct criminal  operations from his prison cell. In 1946 his sentence was commuted, and  he was deported to Italy, where he directed drug traffic and the smuggling  of aliens into the U.S.</p><p>Lucifer In classical mythology, the morning star (the planet Venus at  dawn), personified as a male figure. Lucifer (Latin: �Light-Bearer�) car�  ried a torch and served as herald of the dawn.

He commanded the  legions that drove Mithradates from Bithynia and Pontus to Armenia and  later invaded Armenia and defeated its king, Tigranes. Mutinies prevented  his complete victory, and Lucullus was replaced by Pompey, whom he  opposed in the Senate. His legendary hedonism and extravagance made  the word Lucullan a synonym of �lavish.�</p><p>Lucy Nickname for a remarkably complete (40% intact) hominin skeleton  found by Donald Johanson at Hadar, Eth., in 1974 and dated to 3.2 million  years ago. The specimen is usually classified as Australopithecus afarensis  and suggests�by having long arms, short legs, an apelike chest and jaw,  and a small brain but a relatively humanlike pelvis�that bipedal locomo�  tion preceded the development of a larger (more humanlike) brain in hom�  inin evolution.

He effectively used the prevalent anti-  Semitic and German nationalist currents in Vienna to advance his politi�  cal objectives. He was elected mayor of Vienna in 1895 and transformed  the Austrian capital into a modem city, bringing streetcars, electricity, and  gas under city government control.

In History and Class Consciousness (1923), he developed a Marxist phi�  losophy of history and laid the basis for his literary criticism by linking  the development of form in art with the history of the class struggle. A  major figure during the 1956 Hungarian uprising, he was deported but  was allowed to return in 1957. His works include the essay collection Soul  and Form (1911) and The Historical Novel (1955).

There he  learned guitar, organ, violin, and dancing and came to know the composer  Michel Lambert (1610-96), who introduced him to society and later  became his father-in-law. Lully became a dancer and musician for the king  and at age 30 was put in charge of all royal music. In the 1660s he com�  posed the incidental music for Moliere�s plays as well as those of France�s  great tragedians. In the early 1670s he obtained the sole patent to present  opera and produced the series of �lyric tragedies��most with librettos by  Philippe Quinault (1635-88)�for which he is known, including Alceste  (1674), Atys (1676), and Armide (1686). The orchestra he developed was  an important forerunner of the modern orchestra. A self-inflicted injury  to his toe with his heavy conducting stick led to his death. His style of  composition was imitated throughout Europe.</p><p>Lully, Raymond See Ramon Llull</p><p>lumber Collective term for harvested wood, whether cut into logs, heavy  timbers, or members used in light-frame construction. Lumber is classi�</p><p>fied as hardwood or softwood (see wood). The term often refers specifi�  cally to the products derived from logs in a sawmill. Conversion of logs  to sawed lumber involves debarking, sawing into boards or slabs, resaw�  ing into thinner boards of varying sizes, edging, crosscutting to square the  ends and remove defects, grading according to strength and appearance,  and drying in the open air or in kilns. Drying below the fiber-saturation  point results in shrinkage and generally greater strength, stiffness, and  density and better prepares the wood for finishing. Preservatives are often  applied to protect the wood from deterioration and decay.</p><p>Lumet \Tu-mot\, Sidney (b. June 25, 1924, Philadelphia, Pa., U.S.)  U.S. television and film director. He worked as a child actor in the Yid�  dish theatre and on Broadway. After serving in World War II, he directed  plays and taught acting. He directed more than 200 television dramas for  CBS (1951-57), including Playhouse 90 and Studio One productions,  before making his debut as a movie director with the acclaimed Twelve  Angry Men (1957). He went on to direct commercially successful psy�  chological dramas such as The Fugitive Kind (1960), Fail Safe (1964),  Serpico (1973), Dog Day Afternoon (1975), Network (1976), The Verdict  (1982), and Night Falls on Manhattan (1997).</p><p>Lumiere \ltE-'myer\, Auguste and Louis (respectively b.

In 1882  Louis developed a method of mak�  ing photographic plates, and by 1894  the brothers� factory was producing  15 million plates a year. They  worked on improving Thomas Alva  Edison�s Kinetoscope and patented  their combination movie camera and  projector, the Cinematographe, in  1895. Their film La Sortie des ouvri-  ers de I�usine Lumiere (�Workers  Leaving the Lumiere Factory�),  which they showed to a paying audi�  ence in Paris in 1895, is considered  the first motion picture. In 1896 the brothers, led by Louis, made more  than 40 films recording everyday French life. They made the first news�  reels, sending crews all over the world to shoot new material and show  their films. In addition to the films he directed, Louis served as producer  for some 2,000 films. The brothers also made basic innovations in colour  photography.</p><p>luminaire or light fixture Complete lighting unit, consisting of one  or more lamps (bulbs or tubes that emit light), along with the socket and  other parts that hold the lamp in place and protect it, wiring that connects  the lamp to a power source, and a reflector that helps direct and distrib�  ute the light. Fluorescent fixtures usually have lenses or louvers to shield  the lamp (thus reducing glare) and redirect the light emitted. Luminaires  include both portable and ceiling- or wall-mounted fixtures.</p><p>luminescence Process by which an excited material emits light in a  process not caused solely by a rise in temperature. The excitation is usu�  ally achieved with ultraviolet radiation, X rays, electrons, alpha particles,  electric fields, or chemical energy. The colour, or wavelength, of the light  emitted is determined by the material, while the intensity depends on both  the material and the input energy. Examples of luminescence include light  emissions from neon lamps, luminescent watch dials, television and com�  puter screens, fluorescent lamps, and fireflies. See also bioluminescence;  fluorescence; phosphorescence.</p><p>luminism Painting style that emphasizes a particular clarity of light. It  is characteristic of the works of a group of U.S. painters of the late 19th  century, influenced by the Hudson River school. Typically landscapes or  seascapes, with sky occupying nearly half the composition, luminist  works are distinguished by cool, clear colours and meticulously detailed  objects modeled by light. The most prominent luminist painters were John  Frederick Kensett, Martin Johnson Heade, and Fitz Hugh Lane.</p><p>Lumumba Uo-'mum-boV, Patrice (Hemery) (b. July 2, 1925,  Onalua, Belgian Congo�d.

That same  year his militant nationalism at a  major Pan-African conference in  Accra, Ghana, brought him to promi�  nence. During negotiations in Bel�  gium in 1960, he was asked to form  the first independent Congolese gov�  ernment. His rival Moise Tshombe  immediately announced the seces�  sion of Katanga province. When Bel�  gian troops arrived to sustain the  secession, Lumumba appealed first  to the UN and then to the Soviet  Union. He was dismissed by Pres.</p><p>Joseph Kasavubu and, a short time  later, assassinated by Tshombe loy�  alists. His death caused a scandal  throughout Africa, where he was looked on as a leader of Pan-Africanism.</p><p>Luna Any of a series of unmanned Soviet lunar probes, launched  between 1959 and 1976, responsible for various lunar �firsts.� Luna 2  (1959) was the first spacecraft to strike the Moon; Luna 3 (1959) was the  first to circle the Moon and took the first photographs of its far side. Luna  9 (1966) made the first successful lunar soft landing. Luna 16 (1970) was  the first unmanned spacecraft to carry lunar soil samples back to Earth.  Luna 17 (1970) soft-landed a robot vehicle for exploration; it also con�  tained television equipment and sent live pictures of several miles of the  Moon�s surface.

He worked  in Virginia and Ohio, where he organized the Union Humane Society  (1815), one of the first antislavery societies. In 1821 he founded a news�  paper, the Genius of Universal Emancipation, which he edited in various  places until 1835, when he began publishing another paper, the National  Enquirer (later the Pennsylvania Freeman), in Philadelphia. He traveled  in search of places for former slaves to settle, including Canada and Haiti.</p><p>lung Either of two light, spongy, elastic organs in the chest, used for  breathing. Each is enclosed in a membrane (pleura). Contraction of the  diaphragm and the muscles between the ribs draw air into the lungs through  the trachea, which splits into two primary bronchi, one per lung. Each  bronchus branches into secondary bronchi (one per lobe of lung), tertiary  bronchi (one per segment of lung), and many bronchioles leading to the  pulmonary alveoli. There oxygen in the inspired gas is exchanged for car�  bon dioxide from the blood in the surrounding capillaries. Adequate tissue</p><p>oxygen supply depends on sufficient distribution of air (ventilation) and  blood (perfusion) in the lungs. Lung injuries or diseases (e.g., emphysema,  embolism, pneumonia) can affect either or both.</p><p>lung cancer Malignant tumour of the lung. Four major types  (squamous-cell carcinoma, adenocarcinoma, large-cell carcinoma, and  small-cell carcinoma) have roughly equal prevalence. Most cases are due  to long-term cigarette smoking. Heavy smoking and starting smoking ear�  lier in life increase the risk. Passive inhalation (�secondhand smoke�) is  linked to lung cancer in nonsmokers. Other risk factors include exposure  to radon or asbestos. Symptoms, including coughing (sometimes with  blood), chest pain, and shortness of breath, seldom appeal - until lung can�  cer is advanced, when treatment with surgery, chemotherapy, and radia�  tion or some combination of the three is less effective. Most patients die  within a year of diagnosis.</p><p>lung congestion Distention of blood vessels in the lungs and filling  of the pulmonary alveou with blood. It results from infection, hypertension,  or inadequate heart function (e.g., left-sided heart failure). Congestion  seriously impairs gas exchange, leading to breathing difficulty, bloody  discharge in sputum, and bluish skin tint.</p><p>Lung-men caves See Longmen caves  Lung-shan culture See Longshan culture</p><p>Luni River \'lu-ne\ River, Rajasthan state, western India.

U.S. acting team. Lunt made his acting debut in Boston in  1912 and starred in Clarence on Broadway (1919). Fontanne made her  acting debut in London in 1909 and in New York City in 1910. She and  Lunt married in 1922 and performed with the Theatre Guild from 1924 to  1929. They acted together in more than 25 plays, including The Guards�  men (1924) and Design for Living (1933), the latter of which Noel Cow�  ard wrote for them. Considered the foremost acting couple of the U.S.  theatre, they were acclaimed for the subtlety and effortless cooperation of  their performances, especially in comedies by Coward and George Ber�  nard Shaw.</p><p>Lunyu \Tun-'yiB\ English Analects One of four Confucian texts that,  when published together in 1190 by Zhu Xi, made up the Four Books.  Scholars consider Lunyu the most reliable source of the doctrine of Con�  fucius. It covers almost all the basic ethical concepts of Confucianism�  for example, ren (benevolence), junzi (the superior man), Tian (Heaven),  zhong yong (doctrine of the mean), li (proper conduct), and zheng ming  (rectification of names). It also contains many direct quotations from  Confucius and personal glimpses of the sage as recorded by his disciples.

Its origins are uncertain, but the likely derivation of its name from  lupus (Latin: �wolf�) may signal a connection with a primitive deity who  protected herds from wolves or with the legendary she-wolf who nursed  Romulus and Remus. Each Lupercalia began with the sacrifice of goats and  a dog; two of its priests (Luperci) were then led to the altar and their fore�  heads were anointed with blood. After all had feasted, the Luperci cut  thongs from the skins of the sacrificed animals and ran around the Palatine  hill, striking at any woman who came near them; a blow from the thong  was supposed to bestow fertility.</p><p>lupine or lupin \Tu-pon\ Any of about 200 species of herbaceous and  partly woody plants that make up the genus Lupinus in the pea family  (see legume), found throughout the Mediterranean and especially on the  prairies of western North America.

Herba�  ceous lupines, which grow up to 4 ft (1.25 m) tall, have low, divided leaves  and an upright flower spike, and many are hybridized for gardens. The  name comes from the Latin for �wolf� because these plants were once  thought to deplete, or �wolf,� minerals from the soil; in actuality some  species aid soil fertility through nitrogen fixation.</p><p>Lupino \lu-'pe-no\ family British theatrical family. The earliest mem�  ber, Signor Luppino, flourished c. 1610, probably in Italy. His descendant  George William Luppino (1632-93), a puppet master, immigrated to  England as a political refugee. A later descendant, the scenic artist and  dancer Thomas Frederick Lupino (1749-1845), changed the spelling of  the family name. Another family member, George Hook Lupino (1820-  1902), had 16 children, 10 of whom were dancers. His eldest son, George  Lupino (1853-1932), was a famous clown; George�s son Barry Lupino  (1884-1962) excelled in pantomime and musical comedy; another son,  Stanley Lupino (1894-1942), performed in comedy revues. Stanley�s  nephew Henry Lupino (1892-1959), a Cockney comedian known as  Lupino Lane, created the �Lambeth walk� dance in the musical Me and  My Girl (1937). Stanley�s daughter Ida Lupino (1916-95) moved in 1934  to the U.S., where she starred in movies such as They Drive by Night  (1940), The Sea Wolf (1941), and The Hard Way (1942). One of the first  female film directors, she was noted for The Hitch-Hiker (1953) and The  Bigamist (1953), and she also directed several dramas for television.</p><p>lupus erythematosus Vlii-pos-.er-o-.the-mo-'to-sosV Either of two  inflammatory autoimmune diseases, both more common in women. In the  discoid type, a skin disease, red patches with grayish brown scales appear  on the upper cheeks and nose (often in a butterfly pattern), scalp, lips,  and/or inner cheeks. Sunlight worsens it. Antimalarial drugs may help.  The second type, systemic (disseminated) lupus erythematosus (SLE),  may affect any organ or structure, especially the skin (with marks like  those of the discoid type), kidneys, heart, nervous system, serous  (moisture-forming) membranes (e.g., in synovial joints or lining the abdo�  men), and lymph nodes, with acute episodes and remissions. Symptoms  vary widely. Kidney and central-nervous-system involvement can be life-  threatening. Treatment includes pain relief, control of inflammation, and  trying to limit damage to vital organs.</p><p>Luria, A(leksandr) R(omanovich) (b. July 3, 1902, Kazan,  Russia�d. 1977) Soviet neuropsychologist. After earning degrees in psy�  chology, education, and medicine, he became professor of psychology at  Moscow State University and later head of its department of neuropsy�  chology. Influenced by his former teacher L.S. Vygotsky, he studied lan�  guage disorders and the role of speech in mental development and  retardation. During World War II Luria made advances in brain surgery  and in the restoration of brain functions after trauma. He also developed  theories concerning the functioning of the frontal lobe and the existence  of zones of brain cells working in concert. His books include Higher Cor�  tical Functions in Man (1966), The Working Brain (1973), and Basic  Problems of Neurolinguistics (1976).</p><p>Luria \'lur-ya\, Isaac ben Solomon (b. 1534, Jerusalem�d. Aug. 5,  1572, Safed, Syria) Jewish mystic and founder of a school of Kabbala. He  was brought up in Egypt, where he pursued rabbinic studies. He dedi�  cated himself to the study of the Kabbala with messianic fervour, and in  1570 he journeyed to a centre of the movement in Galilee. He died two  years later in an epidemic, having written little. The Lurianic Kabbala, a  collection of Luria�s doctrines recorded after his death by a pupil, had  great influence on later Jewish mysticism and on Hasidism. It propounds a  theory of the creation and later degeneration of the world and calls for  restoration of the original harmony through ritual meditation and secret  combinations of words.</p><p>Luria \'lur-e-3\, Salvador (Edward) (b. Aug. 13, 1912, Turin,  Italy�d. Feb. 6, 1991, Lexington, Mass., U.S.) Italian-born U.S. biolo�  gist. He fled Italy for France in 1938, arriving in the U.S. in 1940. In 1942  he obtained an electron micrograph of phage particles that confirmed ear�  lier descriptions of them as consisting of a round head and a thin tail. In  1943 he and Max DelbrOck showed that viruses can undergo permanent  changes in their hereditary material. He also proved that the simultaneous  existence of phage-resistant bacteria with phage-sensitive bacteria in the  same culture was a result of the selection of spontaneous bacterial  mutants. In 1945 he and A.D. Hershey demonstrated the existence not only  of such bacterial mutants but also of spontaneous phage mutants. The  three men shared a 1969 Nobel Prize.</p><p>Luristan Bronze Vlur-o-.stanV or Lorestan Bronze \'16r-3-,stan\  Objects excavated since the late 1920s in the valleys of the Zagros Moun�  tains in the Luristan region of western Iran. Dating from c. 1500 to c. 500  bc, they consist of utensils, weapons, jewelry, horse trappings, belt buck�  les, and ritual and votive objects. They are believed to have been pro�  duced either by the Cimmerians or by Indo-European peoples of Media or  Persia.</p><p>Lusaka \lu-'sa-ka\ City (pop., 1999 est.: metro, area, 1,577,000), capi�  tal of Zambia. In the 1890s the area was taken by the British South Africa  Company during the formation of Northern Rhodesia; it became the capi�  tal in 1935. After the federation of Northern and Southern Rhodesia in  1953, it was a centre of the civil disobedience movement that led to the  creation of the independent state of Zambia in 1960, with Lusaka as its  capital. Possessing some light industry, it is also a commercial centre for  the surrounding agricultural region. The University of Zambia (founded  1965) is located nearby.</p><p>Lushun VliB-'shuM or Lu-shun formerly Port Arthur Former city,  since 1950 a district of Dalian city, Liaoning province, northeastern China.  Situated at the southern tip of the Liaodong Peninsula, it was used as a  staging post as early as the 2nd century bc. Fortified under the Ming  dynasty, it was captured by the Manchus in 1633 and served as the seat  of a defense unit under the Qing dynasty. In 1878 it became the chief base  for China�s first modem naval force. Leased to Russia in 1898, it was  captured by Japan (1905) during the Russo-Japanese War and was made  the seat of a provincial government. Under a 1945 treaty it became a  Sino-Soviet military base; the Soviet forces withdrew in 1955.</p><p>Lusitania British ocean liner sunk by a German submarine off the coast  of Ireland on May 7, 1915. The British Admiralty had warned the Lusi�  tania to avoid the area and to use the evasive tactic of zigzagging, but the  crew ignored these recommendations. Though unarmed, the ship was car�  rying munitions for the Allies, and the Germans had circulated warnings  that the ship would be sunk. The loss of life�1,198 people drowned,  including 128 U.S. citizens�outraged public opinion. The U.S. protested  Germany�s action, and Germany limited its submarine campaign against  Britain.

In 1893 Louis  Comfort Tiffany founded the Stourbridge Glass Co. to produce lustred  drinking glasses, bowls, vases, lamps, and jewelry. His lustred glass, pro�  duced by metallic pigments applied to opaque glass, produced a pearly  sheen, whereas that produced in  Europe in the 1870s used transparent  glass, which resulted in a mirrorlike  surface.

Nov. 10, 1483, Eisleben, Saxony�d. Feb. 18, 1546,  Eisleben) German priest who sparked the Reformation. The son of a miner,  he studied philosophy and law before entering an Augustinian monastery  in 1505. He was ordained two years later and continued his theological  studies at the University of Wittenberg, where he became a professor of  biblical studies. He was shocked by the corruption of the clergy on a trip  to Rome in 1510 and was later troubled by doubts centring on fear of  divine retributive justice. His spiritual crisis was resolved when he hit on  the idea of justification by faith, the doctrine that salvation is granted as a  gift through God�s grace. He urged reform of the Roman Catholic church,  protesting the sale of indulgences and other abuses, and in 1517 he dis�  tributed to the archbishop of Mainz and several friends his Ninety-Five  Theses (according to legend, Luther nailed the theses to the door of the  castle church in Wittenberg); the theses questioned Roman Catholic teach�  ing and called for reform. In 1521 he was excommunicated by Pope Leo  IX and declared an outlaw at the Diet of Worms (see Worms, Diet of).  Under the protection of the elector of Saxony, Luther took refuge in Wart-  burg. There he translated the Bible into German; his superbly vigorous  translation has long been regarded as the greatest landmark in the history  of the German ianguage. He later returned to Wittenberg, and in 1525 he  married the former nun Katherina von Bora, with whom he raised six  children. Though his preaching was the principal spark that set off the  Peasants' War (1524-25), his vehement denunciation of the peasants con�  tributed to their defeat. His break with Rome led to the founding of the  Lutheran Church (see Lutheranism); the Lutheran confession of faith or,  Augsburg Confession, was produced with Luther�s sanction by Philipp  Melanchthon in 1530. Luther�s writings included hymns, a liturgy, and  many theological works.</p><p>Lutheranism Protestant movement founded on the principles of Mar�  tin Luther. Lutheranism arose at the start of the Reformation, after Luther  posted his Ninety-five Theses in Wittenberg. It spread through much of Ger�  many and into Scandinavia, where it was established by law. It was  brought to the New World by the colonists of New Netherland and New  Sweden and spread through the U.S. Middle Atlantic states in the 18th  century and the Midwest in the 19th century. Its doctrines are contained  in the catechisms of Luther and in the Augsburg Confession. Lutheran  doctrine emphasizes salvation by faith alone and the primacy of the Bible  as the church�s authority. The Lutheran ministry is one of service�not  special status�and is described as the priesthood of all believers. Luth�  erans accept two sacraments (baptism and the Eucharist) and believe in  predestination to salvation. The Lutheran World Federation is based in  Geneva.

Lan�  guages: Luxembourgian, French, German.</p><p>Religion: Christianity (predominantly Roman Catholic). Currency: euro.  The country has a maximum length of 51 mi (82 km) and a maximum width  of 35 mi (56 km). It is divided into two regions: the Oesling, an extension  of the Ardennes Mountains in the northern third of the country consisting  of a high plateau dissected by river valleys; and the Bon Pays, or Gutland,  a rolling plateau that occupies the rest of the land. Luxembourg�s economy  is largely based on heavy industry and international trade and banking, and  its per capita income is among the highest in the world. It is a constitutional  monarchy with two legislative houses; its chief of state is the grand duke,  and the head of government is the prime minister. At the time of Roman  conquest (53 bc), the area was inhabited by two Belgic tribes, the Treveri  and the Mediomatrici. After ad 400, Germanic tribes invaded the region. It  later came into Charlemagne�s empire. Made a duchy in 1354, it was ceded  to the house of Burgundy in 1443 and to the Habsburgs in 1477. In the mid-  16th century it became part of the Spanish Netherlands. The Congress of  Vienna in 1815 made it a grand duchy and awarded it to The Netherlands.  After an uprising in 1830, its western portion became part of Belgium,  while the remainder was held by The Netherlands. In 1867 the European  powers guaranteed the neutrality and independence of Luxembourg. In the  late 19th century it built a great steel industry by exploiting its extensive  iron ore deposits. It was invaded and occupied by Germany in both world  wars. Following World War II, it abandoned its neutrality by joining NATO  in 1949. It joined the Benelux Economic Union in 1944 and the European  Coal and Steel Community, a forerunner of the European Union, in 1952.  Luxembourg ratified the Maastricht Treaty on European Union in 1992 and  adopted the euro as its official monetary unit in 1999.</p><p>Luxembourg City (pop., 2001 prelim.: 76,833), capital of Luxembourg.

Its name has been given to the southern half of the ruins of  Thebes. It is centred on the Great Temple of Amon, which was built on the  eastern bank of the Nile River by King Amenhotep III in the 14th century  bc. Tutankhamen and Horemheb completed the temple, and Ramses II added  to it. Ruins include pillars and courts of the original temple as well as the  remains of Coptic churches and a mosque. The modern city serves as a  tourist centre and as a market for the surrounding agricultural district. See  also Karnak.</p><p>luxury tax Excise levy on goods or services considered to be luxuries  rather than necessities (e.g., jewelry and perfume). Luxury taxes may be  levied with the intent of taxing the rich or in a deliberate effort to alter  consumption patterns, either for moral reasons or in times of national  emergency. Today revenue productivity generally overshadows the moral  argument.</p><p>Luyia See Luhya</p><p>Luzon \lii-'z6n\ Island (pop., 2000: 37,909,589), Philippines.

It was taken by the  Cossacks in 1648 and by the Swedes in 1704. Given to Austria in 1772,  it became the capital of the Austrian province of Galicia. It passed to  Poland in 1919, after an unsuccessful attempt by Ukrainians to set up a  republic (1918). It was seized by the Soviet Union in 1939 and, after Ger�  man occupation, annexed by the Soviets in 1945. It is now a centre for  Ukrainian culture and the seat of a university (founded 1661).</p><p>Lvov \l3-'v6f\, Georgy (Yevgenyevich), Prince (b. Nov. 2, 1861,  Popovka, near Tula, Russia�d.

In 1905 he joined the liberal Constitutional  Democratic Party and was elected to the first Duma (1906). He became  chairman of the All-Russian Union of Zemstvos (1914) and won the  respect of political liberals and army commanders. In March 1917 he  became premier but was unable to satisfy the increasingly radical  demands of the populace. He resigned in July, after a major left-wing  demonstration, in favour of Aleksandr Kerensky.

Situated  north of the Taurus Mountains in present-day Turkey, in ancient times it  was bounded by the regions of Caria and Pamphylia. It was ruled by Alex�  ander the Great, the Seleucids, the Attalids, and, finally, the Romans. Under  Rome it was attached to Galatia and Cappadocia. From Seleucid times on,  Iconium (modem Konya) served as its capital. It was visited by St. Paul  and by the 4th century had developed an organized ecclesiastical system.</p><p>lyceum Ml-'se-omV movement Form of adult education popular in the  U.S. during the mid-19th century. The lyceums were voluntary local asso�  ciations that sponsored lectures and debates on topics of current interest.  The first was founded in 1826, and by 1834 there were approximately  3,000 in the Northeast and Midwest. They attracted such speakers as Ralph  Waldo Emerson, Frederick Douglass, Henry David Thoreau, Daniel Webster,  Nathaniel Hawthorne, and Susan B. Anthony. The movement began to  decline with the outbreak of the Civil War and eventually blended into the  postbellum Chautauqua movement. In their heyday the lyceums contrib�  uted to the broadening of the school curricula and the development of  local museums and libraries.</p><p>lychee See litchi</p><p>Lycia Vli-shoV Ancient district, southwestern Anatolia.

Legendary founder of the  legal institutions of ancient Sparta. Because ancient sources give differ�  ing accounts of his career, some scholars conclude that he was not a his�  torical person, but many believe that a man named Lycurgus instituted  drastic reforms in Sparta after the revolt of the helots in the 7th century  bc. Lycurgus is thought to have devised the militarized communal system  that made Sparta unique among Greek city-states and to have determined  the powers of the council and the assembly.</p><p>Lycurgus (b. c. 390� d. 324 bc) Athenian orator and statesman. He sup�  ported Demosthenes in opposing Macedonia. As controller of state finances  (338-326), he was noted for his efficient administration and vigorous  prosecution of corrupt officials. He reconstituted the army and remodeled  the fleet, carried on a major building program that included reconstruc�  tion of the theatre of Dionysus, produced the official edition of the dra�  mas of Aeschylus, Sophocles, and Euripides, and worked to restore Athenian  cults and festivals.</p><p>Lydia Ancient land, western Anatolia.

Nov. 14, 1797, Kinnordy, Forfarshire,  Scot.�d. Feb. 22, 1875, London,</p><p>Eng.) Scottish geologist. While  studying law at the University of  Oxford, he became interested in  geology and later met such notable  geologists as Alexander von Humboldt  and Georges Cuvier. Lyell came to  believe that there were natural (as  opposed to supernatural) explana�  tions for all geologic phenomena, a  position he supported with many  examples in his three-volume Prin�  ciples of Geology (1830�33). A rec�  ognized leader in his field, he gained  the friendship of other well-known  men of science, including the Her-  SCHEL FAMILY and CHARLES DARWIN,  whose Origin of Species (1859) per�  suaded Lyell to accept evolution.</p><p>Lyell was largely responsible for the  general acceptance of the concept of  uniformitarianism in geology.</p><p>Lyly \'li-le\, John (b. 1554?, Kent,</p><p>Eng.�d. November 1606, London) English writer. Educated at Oxford,  Lyly gained fame in London with two prose romances, Euphues (1578)  and Euphues and His England (1580). The novels inspired euphuism, an  elegant, extravagant Elizabethan literary style, and made Lyly the first  English prose stylist to leave an enduring impression on the language. As  a dramatist he also contributed to the development of prose dialogue in  English comedy, a genre to which he devoted himself almost exclusively  after 1580. Endimion (performed 1588) is considered his finest play.</p><p>Lyme disease Tick-borne bacterial disease. It was identified in 1975  and named for Old Lyme, Conn. It is caused by a spirochete, Borrelia  burgdorferi, transmitted by ticks, which pick it up in the blood of infected  animals, mostly deer. Humans can be bitten by ticks in tall grass or fallen  leaves. Lyme disease has three stages: a target-shaped rash, often with  flulike symptoms; migrating arthritic pain and neurological symptoms  (disturbances to memory, vision, or locomotion); and crippling arthritis  with symptoms like those of multiple sclerosis and sometimes with facial  paralysis, meningitis, or memory loss. Most cases do not progress beyond  the first stage, but those that do reach the third stage within two years.  Prevention involves avoiding tick bites. Diagnosis can be difficult, espe�  cially if the initial rash is not noticed. Early antibiotic treatment can pre�  vent progression. Advanced cases need more powerful antibiotics, and  symptoms may recur.</p><p>lymph Pale fluid that bathes tissues, maintaining fluid balance and  removing bacteria. It enters the blood system at a vein under the collar�  bone that it reaches via channels and ducts, being driven through them  mainly by surrounding muscle activity. The lymphatic organs (spleen and  thymus) and lymph nodes filter out bacteria and other particles the lymph  takes up from body tissues. Lymph contains lymphocytes and macrophages,  the primary cells of the immune system. See also lymphatic system.</p><p>lymph node Small, rounded mass of lymphoid tissue contained in con�  nective tissue. They occur all along lymphatic vessels, with clusters in cer�  tain areas (e.g., neck, groin, armpits). They filter bacteria and other foreign  materials out of lymph and expose them to lymphocytes and macrophages  that can engulf them; these cells multiply in response to accumulation of  such materials, which is why lymph nodes swell during infections. The  nodes also produce lymphocytes and antibodies, to be carried by lymph  throughout the lymphatic system. In Hodgkin disease and other lymphomas,  malignant lymph cells proliferate, causing lymph node enlargement. Other  cancers often invade lymphatic vessels, which can carry cells from the</p><p>tumour to lymph nodes, where they are trapped and grow into secondary  tumours. Lymph nodes are therefore removed in cancer surgery to detect  or prevent tumour spread.</p><p>lymphatic system System of lymph nodes, vessels, and nodules and lym�  phoid tissue, including the thymus, spleen, tonsils, and bone marrow, through  which lymph circulates and is filtered. Its primary function is to return pro�  teins, waste products, and fluids to the blood; molecules too big to enter the  capillaries pass through the more permeable walls of lymphatic vessels.  Valves keep lymph flowing in one direction, more slowly than blood and at  a lower pressure. The lymphatic system also has a role in the immune system.  Nodes filter bacteria and foreign matter from lymph. Smaller nodules,  which often produce lymphocytes, form in areas more exposed to such mate�  rials. They can merge and become permanent, as in the tonsils. Blockage of  a lymph vessel may cause fluid to collect in the tissues, producing lymphe�  dema (tissue swelling). Other lymphatic system disorders include lympho�  cytic LEUKEMIAS and LYMPHOMA. See also RETICULOENDOTHELIAL SYSTEM.</p><p>lymphocyte Type of leukocyte fundamental to the immune system, regu�  lating and participating in acquired  immunity. Each has receptor mol�  ecules on its surface that bind to a  specific antigen. The two primary  types, B cells and T cells, originate  from stem cells in bone aaarrow and  travel to lymphoid tissues. When a B  cell binds to an antigen, it multiplies  to form a clone of identical cells.</p><p>Some of these, acted on by helper T  cells, differentiate into plasma cells  that produce antibodies against the  antigen. Others (memory cells) mul�  tiply, providing long-term immunity to  the antigen.</p><p>lymphoid tissue Cells, tissues, and organs composing the immune sys�  tem, including the bone aaarrow, thymus, spleen, and lymph nodes. The most  highly organized components are the thymus and lymph nodes, and the  least organized are the cells that wander in the loose connective-tissue  spaces under membranes lining most body systems, where they can estab�  lish lymph nodules (local lymphocyte production centre) in response to  antigens. The most common lymphoid tissue cell is the lymphocyte. Oth�  ers are macrophages, which engulf foreign materials and probably alter  them to initiate the immune response, and reticular cells, which produce  and maintain thin networks of fibres as a framework for most lymphoid  organs. See also immunity; lymphatic system.</p><p>lymphoma \lim-'fo-m9\ Any of a group of malignant diseases (see  cancer) that usually start in the lymph nodes or lymphoid tissues. The two  major types, Hodgkin disease and non-Hodgkin lymphoma, each have sev�  eral subtypes. Diagnosis of either type requires biopsy, usually from the  lymph nodes. Non-Hodgkin lymphomas may be diffuse (widespread) or  nodular (concentrated in nodules); nodular lymphomas generally develop  more slowly.</p><p>Lynch, David (b. Jan. 20, 1946, Missoula, Mont., U.S.) U.S. director.  Trained as an artist, he studied in Europe and began experimenting with  film in the late 1960s. In 1977 he made his first feature, Eraserhead, a  grotesque and nightmarish film that became a cult favourite. He directed  the critically acclaimed The Elephant Man (1980), the science-fiction  Dune (1984), and the bizarre mystery Blue Velvet (1986). He was noted  for his disturbing and dark view of life. His later films include Wild at  Heart (1990, Golden Palm), Lost Highway (1997), The Straight Story  (1999), and Mulholland Drive (2001). He also created the offbeat televi�  sion series Twin Peaks (1990-91).</p><p>lynching Execution of a presumed offender by a mob without trial,  under the pretense of administering justice. It sometimes involves tortur�  ing the victim and mutilating the body. Lynching has often occurred under  unsettled social conditions. The term derives from the name of Charles  Lynch, a Virginian who headed an irregular court to persecute loyalists  during the American Revolution. In the United States, lynching was widely  used in the post-Reconstruction South against blacks, often to intimidate  other blacks from exercising their civil rights.</p><p>Lynd Vlind\, Robert (Stoughton); and Lynd, Helen orig.

The North American lynx  {Lynx canadensis) is regarded as distinct from the Eurasian and Spanish  (Iberian) species. The lynx has long legs, large paws, tufted ears, hairy  soles, and a broad, short head. Its coat, which forms a bushy ruff on the  neck, is tawny to cream-coloured and mottled with brown and black. Its  dense, soft winter fur has been used for trimming garments. Lynx are  approximately 3CM10 in. (80-100 cm) long, without the 4-8-in. (10-20-  cm) tail, and stand about 24 in. (60 cm) high at the shoulder. They weigh  20�45 lb (10-20 kg). Nocturnal and silent except during mating season,  lynx live alone or in small groups. They climb and swim well and feed  on birds, small mammals, and occasionally deer. Some regional popula�  tions of lynx are considered endangered.</p><p>Lyon \'lyo n \ English Lyons Ylyo n , 'll-3nz\ City (pop., 1999: city,  445,452; metro, area, 1,348,932), east-central France.

Lyrelike instruments existed in Sumer before 2000 bc.  Greek lyres were of two types, the kithara and the lyra. The latter had a  rounded body and a curved back�often a tortoiseshell�and a skin belly.  It was the instrument of the amateur; professionals used the more elabo�  rate kithara. In ancient Greece the lyre was an attribute of Apollo and  symbolized wisdom and moderation. In medieval Europe new varieties of  lyre emerged that, like the kithara, were box lyres, although their precise</p><p>relation to the lyres of Classical  antiquity is not known. The lyres of  modern East Africa probably reflect  ancient diffusion of the instrument  via Egypt.</p><p>lyrebird Either of two species of  insectivorous suboscine passerines  (family Menuridae) named for the  shape of their extremely long tail  when spread in courtship display.</p><p>Found in forests in southeastern Aus�  tralia, lyrebirds are ground dwellers  with chickenlike bodies. About 40  in. (1 m) in total length, the male  superb lyrebird is the longest of the  passerines. He displays in a small  clearing, bringing his tail forward so  that the beautiful white plumes form  a canopy over his head and the lyre�  like feathers stand out to the side. In  this position, while prancing in  rhythm, he sings far-carrying melo�  dious notes interspersed with perfect  mimicry of other creatures and even  of mechanical sounds.</p><p>lyric Verse or poem that can, or supposedly can, be sung to musical  accompaniment (in ancient times, usually a lyre) or that expresses intense  personal emotion in a manner suggestive of a song. Lyric poetry expresses  the thoughts and feelings of the poet and is sometimes contrasted with  narrative poetry and verse drama, which relate events in the form of a  story. The elegy, ode, and sonnet are important forms of lyric poetry.</p><p>Lysander Ul-'san-dorV (d. 395 bc, Haliartus, Boeotia) Spartan leader in  the Peloponnesian War. In his first year as admiral he won the support of  the Persian king Cyrus the Younger. He defeated the Athenian fleet at  Notium (406), causing the dismissal of Alcibiades. In 405 he destroyed the  Athenian fleet at the Battle of Aegospotami; this action closed the grain  route and starved the city into surrender. Lysander installed the Thirty  Tyrants and made his friends governors of Athens�s former empire. He  suffered a defeat when Sparta allowed the restoration of democracy in  Athens (403). Having led an army of Sparta�s northern allies into Boeo�  tia, he was killed while attacking Haliartus.</p><p>Lysenko Uo-'seq-koV Trofim (Denisovich) (b. 1898, Karlovka,  Ukraine, Russian Empire�d.

As director of the  Soviet Academy of Sciences� Insti�  tute of Genetics (1940-65), he  became the controversial �dictator�  of Stalinist biology. Claiming,  among other things, that wheat  plants raised in the appropriate envi�  ronment would produce seeds of rye,  he promised greater, more rapid, and  less costly increases in crop yields  than other biologists believed pos�  sible.

He ranks with Antiphon as  a writer of clear, simple prose of  great effectiveness, and his style  became one model for Attic Greek  prose. Many of his writings survive.</p><p>lysine \'ll-,sen\ One of the essential  amino acids, present in many com�  mon proteins. Its proportion in the  proteins of some important food  plants (including wheat and com) is  so small that populations dependent  on these grains as the sole source of  dietary protein suffer from lysine  deficiency, affecting growth in chil�  dren and general well-being in  adults. It is used in biochemical and  nutritional research, in pharmaceuti�  cals, in fortified foods, and as a nutri�  tional supplement and feed additive.</p><p>Lysippus \ll-'si-p3s\ or Lysippos</p><p>(fl. 4th century bc, Sicyon, Greece)</p><p>Greek sculptor. He was famous for the new and slender proportions of his  figures and for their lifelike naturalism. He reportedly made more than  1,500 works, most in bronze. None survive, but some copies may be reli�  ably ascribed to him, including Apoxyomenos, a young athlete scraping  oil from his skin. Another key work is the colossal Heracles at Sicyon.  He made many portrait busts of Alexander the Great from boyhood on; it  was said that Alexander would have no other sculptor portray him.</p><p>lysogeny Ml-'sa-jo-neX Type of life cycle that takes place in a bacte�  riophage after it infects certain types of bacteria. The bacteriophage�s  genome (entire collection of genes) enters the chromosome of the host  bacterium and replicates together with it. No offspring viruses are pro�  duced; instead, the infecting virus lies dormant within the host�s chro�  mosome until the host is exposed to certain stimuli, such as ultraviolet  light. At that point, the virus genome is removed from the host chromo�  some and begins to multiply, forming new viruses. Finally, the bacterial  host is destroyed (lysed), releasing virus particles into the environment to  infect new bacterial cells.</p><p>lysosome \H-s3-,som\ Membrane-enclosed organelle found in all  eukaryotic cells (see eukaryote) that is responsible for the cell�s digestion  of macromolecules, old cell parts, and microorganisms.

Bom into a family of court painters, Ma Yuan  began his career under the emperor Xiaozong, became daizhao (�painter-  in-attendance�) under Emperor Guangzong, and received the highest  honour, the Golden Belt, under Emperor Ningzong. Apart from these  facts, little is known about Ma�s life. He occasionally painted flowers and  figure subjects, but it was in landscape painting that his genius lay. He  executed a number of large landscape screens, all of which are now lost.  He also painted tall hanging scrolls depicting steep mountains with  streams, waterfalls, and vigorously yet elegantly rendered pine trees. In  many of his works, the mountains are pushed to one side, creating a �one  comer� composition; between the distant mountains and the foreground  rocks, where a scholar may be sitting, lies an expanse of empty space with  a suggestion of mist or water. Ma�s style was popular with late Song paint�  ers, and it is often difficult to distinguish his works from those of his fol�  lowers. The romantic landscape style of Ma and his contemporary Xia Gui  inspired a school of painting that came to be known as the Ma-Xia school,  characterized by asymmetrical compositions with simplified ink tones and  angular brushstrokes.</p></section><section><p>maa-alused Vma- , a-lu- l sed\ In Estonian folk religion, mysterious elves  living under the earth. These small folk had suitably tiny possessions, and  their world was differently oriented from the mortal world above them  (up was down and right was left).

He worked as a reporter in Chicago and New York City  (1914-26) before collaborating with Edward Shelden on the play Lulu  Belle (1926). With Ben Hecht he wrote the Broadway hits The Front Page  (1928; film, 1931) and Twentieth Century (1932; film, 1934) and several  later plays noted for their graphic, crisp dialogue. Their screenplays  included the film adaptations of their own plays and Wuthering Heights  (1939), and they wrote and directed movies such as Crime Without Pas�  sion (1934), The Scoundrel (1935), and Soak the Rich (1936).

In 1932 he commanded the troops that  evicted the Bonus Army. In 1937 he took over command of the Philippine  military. At the outbreak of World War II he was recalled to active duty;  he led the combined Philippine-U.S. forces in the Philippines until it was  overrun by the Japanese (1942). From Australia, he commanded U.S.  forces in the South Pacific and directed the recapture of strategic islands,  returning as promised (�I shall return�) to liberate the Philippines in 1944.  Promoted to general of the army, he received Japan�s surrender on Sept.  2, 1945. As Allied commander of the postwar occupation of Japan (1945-  51), he directed the restoration of the country�s economy and the draft�  ing of a democratic constitution. As commander of UN forces in the  Korean War in 1950, he stemmed the advance of North Korean troops.  His request for authority to bomb China was rejected by Pres. Harry Tru�  man; when MacArthur made the dispute public, Truman relieved him of  his command, for insubordination. He returned to the U.S. to a hero�s  welcome, though many deplored his egotism.

They believed that the effect of a  painting on the spectator should derive from the painted surface itself,  rather than from any ideological message or narrative. The Macchiaioli  used a sketch technique to record their initial impressions of nature�often  as seen from a distance�by means of colour and light. Their theory,  similar to that of the French Impressionists, was even more concerned with  the experimental use of colour. The most outstanding artist of the group  was the Florentine Giovanni Fattori.</p><p>MacDiarmid, Alan G. (b. April 14, 1927, Masterson, N.Z.) U.S.  chemist.

Located on a high plateau studded with mountains, Macedonia is  one of the poorest countries in Europe. Although its importance has dimin�  ished recently, agriculture remains central to the economy, with tobacco,  fruit, vegetables, and wine notable. Sheepherding is also significant. The  manufacturing base includes iron and steel, textiles, and chemicals and  chemical products. Macedonia is a republic with one legislative house; its  head of state is the president, and the head of government is the prime  minister. The Macedonian region has been inhabited since before 7000  bc. Under Roman rule, part of the region was incorporated into the prov�  ince of Moesia in ad 29. It was settled by Slavic tribes by the mid-6th  century and was Christianized during the 9th century. Seized by the Bul�  garians in 1185, it was ruled by the Ottoman Empire from 1371 to 1912.  The north and centre of the region were annexed by Serbia in 1913 and  became part of the Kingdom of Serbs, Croats, and Slovenes (later Yugo�  slavia) in 1918. When Yugoslavia was partitioned by the Axis Powers in  1941, Yugoslav Macedonia was occupied principally by Bulgaria. Mace�  donia once again became a republic of Yugoslavia in 1946. After Croatia  and Slovenia seceded from Yugoslavia, fear of Serbian dominance  prompted Macedonia to declare its independence in 1991. In deference to  Greece, which also has an area traditionally known as Macedonia, the  country joined the United Nations in 1993 under the name The Former  Yugoslav Republic of Macedonia and normalized relations with Greece  in 1995.

Another conflict, fought in 149-148, may be considered a  fourth Macedonian War; it resulted in a decisive Roman victory, and in  its aftermath Macedonia became the empire�s first province.</p><p>Macfadden, Bernarr orig. Bernard Adolphus McFadden (b.</p><p>Aug. 16, 1868, near Mill Spring, Mo., U.S.�d. Oct. 12,1955, Jersey City,  N.J.) U.S. publisher and champion of physical health. A sickly orphan by  age 11, he began in his teens to increase his strength as an act of defi�  ance. In 1899 he began publishing Physical Culture magazine, and in later  decades he built up a publishing empire, bringing out the first confession  magazine, True Story (1919), followed by True Romances (1923), True  Detective Mystery Magazine (1924), and other periodicals. Macfadden  also toured widely to promote his message of vigorous physical exercise  and to preach about the dangers of alcohol, drugs, gluttony, corsets, prud�  ishness, tea, coffee, and white bread. Shocking to Victorian sentiments  were his advocacy of a diet consisting of carrots, beans, nuts, and raw  eggs and his encouragement of sleeping on the floor, nudity, and �physi�  cal love.� To promote such �love,� he encouraged openness about sexual  matters and invented a device to enlarge men�s penises. To exemplify fit�  ness, he walked five miles daily to his office in Manhattan in bare feet  while carrying a 40-pound bag of sand. He also staged the first physique  (bodybuilding) contest in America (1903) and fostered the rise of fitness  icon Charles Atlas. Macfadden� s bids for the presidency, U.S. Senate, and  governorship of Florida all failed. Physically fit into old age, he para�  chuted into Paris on his 84th birthday.</p><p>Mach Vmak,\ English VmakX, Ernst (b. Feb. 18, 1838, Chirlitz-Turas,  Moravia�d. Feb. 19, 1916, Haar, Ger.) Austrian physicist and philoso�  pher. After earning a doctorate in physics in 1860, he taught at the Uni�  versities of Vienna and Graz as well as Charles University in Prague.  Interested in the psychology and physiology of sensation, in the 1860s he  discovered the physiological phenomenon known as Mach�s bands, the  tendency of the human eye to see bright or dark bands near the bound�  aries between areas of sharply dif�  fering illumination. He later studied  movement and acceleration and  developed optical and photographic  techniques for measuring sound  waves and wave propagation. In  1887 he established the principles of  supersonics and the Mach number,  the ratio of the velocity of an object  to the velocity of sound. He also pro�  posed the theory of inertia known as  Mach�s principle. In Contributions  to the Analysis of the Sensations  (1886), he asserted that all knowl�  edge is derived from sensory expe�  rience or observation.</p><p>Machado de Assis \ma-'sha-do-  de-a-'sesV, Joaquim Maria (b.</p><p>June 21, 1839, Rio de Janeiro,</p><p>Braz.�d. Sept. 29, 1908, Rio de Jan�  eiro) Brazilian poet, novelist, and  short-story writer. Machado began to  write in his spare time while work�  ing as a printer�s apprentice. By  1869 he was a successful man of let�  ters. His witty, pessimistic works,  rooted in European cultural tradi�  tions, include the eccentric first-  person narrative Epitaph of a Small  Winner (1881) and the novels Phi�  losopher or Dog? (1891) and Dom  Casmurro (1899), the latter his mas�  terpiece. Considered the classic mas�  ter of Brazilian literature, he became  the first president of the Brazilian  Academy of Letters in 1896.</p><p>Machaut \ma-'sho\ / Guillaume  de or Guillaume de Machault</p><p>(b. c. 1300, Machault, France�d.</p><p>1377, Reims) French poet and com�</p><p>poser. After possibly receiving a university education and taking holy  orders, he traveled throughout Europe as secretary to the king of Bohe�  mia. He was appointed canon of Reims cathedral in 1337. After the king�s  death, Machaut was supported by several royal patrons, including the  duke de Berry, and King Charles V. Beside 14 narrative poems incorpo�  rating short lyrics, he wrote more than 400 separate lyric poems. He wrote  dozens of musical compositions in each of the genres of formes fixes. He  also composed the first complete setting of the mass for four voices, and  he was the outstanding figure of the Ars Nova. His poetry is noted chiefly  for its technical innovations. Geoffrey Chaucer�s Book of the Duchesse  shows the influence of Machaut.</p><p>Machiavelli V.ma-ke-o-'vel-eV Niccolo (b. May 3, 1469, Florence�d.  June 21, 1527, Florence) Italian  statesman, historian, and political  theorist. He rose to power after the  overthrow of Girolamo Savonarola  in 1498. Working as a diplomat for  14 years, he came in contact with the  most powerful figures in Europe. He  was dismissed when the Medici fam�  ily returned to power in 1512, and  during the next year he was arrested  and tortured for conspiracy. Though  soon released, he was not permitted  to return to public office. His famous  treatise The Prince (1513, published  1532) is a handbook for rulers;  though dedicated to Lorenzo de' Med�  ici, ruler of Florence from 1513, it  failed to win Machiavelli his favour.</p><p>Machiavelli viewed The Prince as an  objective description of political  reality. Because he viewed human  nature as venal, grasping, and thor�  oughly self-serving, he suggested that ruthless cunning is appropriate to  the conduct of government. Though admired for its incisive brilliance, the  book also has been widely condemned as cynical and amoral, and  �Machiavellian� has come to mean deceitful, unscrupulous, and manipu�  lative. His other works include a set of discourses on Livy (completed c.  1518), the comedy The Mandrake (completed c. 1518), The Art of War  (published 1521), and the Florentine Histories (completed c. 1525).</p><p>machine Device that amplifies or replaces human or animal effort to  accomplish a physical task. A machine may be further defined as a device  consisting of two or more parts that transmit or modify force and motion  in order to do work. The five simple machines are the lever, the wedge, the  wheel and axle, the pulley, and the screw; all complex machines are com�  binations of these basic devices. The operation of a machine may involve  the transformation of chemical, thermal, electrical, or nuclear energy into  mechanical energy, or vice versa. All machines have an input, an output,  and a transforming or modifying and transmitting device. Machines that  receive their input energy from a natural source (such as air currents, mov�  ing water, coal, petroleum, or uranium) and transform it into mechanical  energy are known as prime movers; examples include windmills, water�  wheels, TURBINES, STEAM ENGINES, and INTERNAL-COMBUSTION ENGINES.</p><p>machine gun Automatic weapon capable of rapid, sustained fire, usu�  ally 500-1,000 rounds per minute. Developed in the late 19th century by  such inventors as Hiram Maxim, it profoundly altered modem warfare. The  World War I battlefield was dominated by the belt-fed machine gun, which  remained little changed into World War II. Modem machine guns are clas�  sified into three groups: the squad automatic weapon, chambered for small-  calibre assault-rifle ammunition and operated by one soldier; the general-  purpose machine gun, firing full-power rifle ammunition and operated by  two; and the heavy machine gun, firing rounds of 12.7 mm (.5 in) or higher  and often mounted on an armoured vehicle. See also submachine gun.</p><p>machine language or machine code Elemental language of com�  puters, consisting of a string of 0s and Is. Because machine language is  the lowest-level computer language and the only language that comput�  ers directly understand, a program written in a more sophisticated lan�  guage (e.g., C, Pascal) must be converted to machine language prior to  execution. This is done via a compiler or assembler. The resulting binary  file (also called an executable file) can then be executed by the CPU.

Machine tools date from the  invention of the steam engine in the 18th century; most common machine  tools were designed by the middle of the 19th century. Today dozens of  different machine tools are used in the workshops of home and industry.  They are frequently classified into seven types: turning machines such as  lathes; shapers and planers; power drills or drill presses; milling machines;  grinding machines; power saws; and presses (e.g., punch presses).</p><p>machismo \ma-'chez-mo\ Exaggerated pride in masculinity, perceived  as power, often coupled with a minimal sense of responsibility and dis�  regard of consequences. In machismo there is supreme valuation of char�  acteristics culturally associated with the masculine and a denigration of  characteristics associated with the feminine. It has for centuries been a  strong current in Latin American politics and society. Caudillos (military  dictators), prominent in the history of Latin America, have typified  machismo with their bold and authoritarian approach to government and  their willingness to employ violence to achieve their ends.</p><p>Mach's principle Vmaks\ Hypothesis that the inertial forces acting on  a body in accelerated motion are determined by the quantity and distri�  bution of matter in the universe. Albert Einstein found its suggested con�  nection between geometry and matter helpful in formulating his theory of  general relativity; unaware that George Berkeley had proposed similar views  in the 18th century, he attributed the idea to Ernst Mach. He abandoned  the principle when he realized that inertia is assumed in the geodesic  equation of motion (see geodesy) and need not depend on the existence  of matter elsewhere in the universe.</p><p>Machu Picchu \�ma-chu- , pek-chu\ Ancient fortress city of the Incas in  the Andes Mountains, south-central  Peru. Perched near Cuzco in a narrow  saddle between two sharp peaks, at  an elevation of 7,710 ft (2,350 m), it  escaped detection by the Spaniards,  and its existence was made known  only in 1911 by U.S. explorer Hiram  Bingham. One of the few pre-  Columbian urban centres found  nearly intact, it is about 5 sq mi (13 sq  km) in area and includes a temple and  a citadel. The period of occupancy is  uncertain.

He believed in the compatibility of individualism and social  organization and saw societies as evolving from highly communal states  to states in which individual functions and group affiliations were  extremely specialized. His works included The Modern State (1926),  Leviathan and the People (1939), and The Web of Government (1947).</p><p>Mack, Connie orig.

Scottish-born Cana�  dian politician, first Liberal prime minister of Canada (1873-78). He emi�  grated to Canada West (now Ontario) in 1842. In 1852 he became editor  of a local Liberal newspaper and befriended George Brown, leader of the  Reform Party. When the Dominion of Canada was created in 1867, Mack�  enzie was elected to the House of Commons, where he led the Liberal</p><p>opposition. As prime minister, his efforts at renewed reciprocity with the  U.S. failed to address economic concerns, and his government was  defeated in 1878.

In 1788 he set up a trading post,  Fort Chipewyan, on Lake Athabasca. From there he began an expedition  (1789) that followed the Mackenzie River from Great Slave Lake to the  Arctic Ocean. In 1793 he journeyed from Fort Chipewyan through the  Rocky Mountains to the Pacific coast, thereby becoming the first Euro�  pean to complete a transcontinental crossing north of Mexico.</p><p>Mackenzie, Sir (Edward Montague) Compton (b.

Educated at Oxford University, he  gave up legal studies to finish his first play, The Gentleman in Grey (1906).  During World War I he directed the Aegean Intelligence Service in Syria;  when he wrote about those experiences in Greek Memories (1932), he  was prosecuted under Britain�s Official Secrets Act. He founded Gramo�  phone magazine in 1923 and edited it until 1962. He served as rector of  Glasgow University (1931-34) and as literary critic for the London Daily  Mail ; his more than 100 novels, plays, and biographies include 10 vol�  umes of memoirs.</p><p>Mackenzie, Sir James (b.

His classic The Study  of the Pulse (1902) described an instrument called a polygraph, which  simultaneously recorded arterial and venous pulses so that they could be  correlated with the heartbeat to distinguish harmless from dangerous  irregularities. A pioneer in the study of cardiac arrhythmia, he also proved  the efficacy of digitalis for its treatment.</p><p>Mackenzie, William Lyon (b. March 12, 1795, Springfield, Angus,  Scot.�d. Aug. 28, 1861, Toronto) Scottish-born Canadian journalist and  political agitator. He immigrated to Canada in 1820 and became a mer�  chant in Upper Canada (later Ontario). In 1824 he founded a newspaper  in Queenston, the Colonial Advocate, in which he criticized the ruling  oligarchy in Upper Canada. Elected to the province�s assembly (1828�  36), he was expelled six times by the conservative majority for his news�  paper� s invectives against the government. A list of Canadian grievances  against British colonial rule that he published led to the recall of the prov�  ince�s governor. In 1837 he led 800 followers in an unsuccessful attempt  to overthrow the provincial government. After attempting to rally his  forces on Navy Island in the Niagara River, N.Y., he was jailed for vio�  lating U.S. neutrality laws. He returned to Canada in 1849 and later served  in the Canadian Parliament (1851-58).</p><p>Mackenzie River River system, Northwest Territories, Canada.

He grew  up in Nashville, where his parents ran a hotel that catered to traveling  performers. He was in the mule business for 20 years; after the trucking  industry put him out of business, he became a professional musician. Per�  forming as Uncle Dave Macon, he entertained audiences with his jovial  folk tunes, such as �Go Long Mule,� and energetic showmanship. He is  considered the first individual to become a star of the Grand Ole Opry,  and he was an Opry regular from the mid-1920s until his death.</p><p>Macon, Nathaniel (b. Dec. 17, 1758, Edgecombe, N.C.�d. June 29,  1837, Warren county, N.C., U.S.) U.S. politician. He fought in the Ameri�  can Revolution and served in the North Carolina legislature (1781-85).  Elected to the U.S. House of Representatives (1791-1815), he served as  speaker (1801-07) and was a leading Anti-Federalist. In the Senate (1815�  28) he continued to support states' rights and opposed legislation to  strengthen the central government.</p><p>Macphail, Agnes Campbell (b.

In 1921, the first year women could vote in national elections in Canada,  she was elected to the Canadian House of Commons as its first female  member; she served until 1940. She advocated prison reform and wom�  en�s rights as well as a protective tariff. She was the first female Canadian  delegate to the League of Nations. Elected to the Ontario legislature (1943-  45, 1948-51), she sponsored the province�s first equal-pay legislation.</p><p>Macquarie \mo-'kwar-e\, Lachlan (b. Jan. 31, 1761, Ulva,  Argyllshire, Scot.�d. July 1, 1824, London, Eng.) British soldier and  colonial governor. He served with the British army in North America,  Europe, the West Indies, and India; in 1809 he was appointed governor  of New South Wales, Australia, where he replaced the corrupt military  corps that had overthrown the previous governor, William Bligh. He began  a program of public works construction and town planning that gave  opportunities to Emancipists (freed convicts), established the colony�s  currency, and encouraged exploration and settlement. His policy favour�  ing Emancipist agriculture angered the large landowners and sheep farm�  ers (Exclusionists), and he was recalled in 1821.</p><p>Macquarie Harbour \m9-'kwar-e\ Inlet of the Indian Ocean, west�  ern Tasmania, Australia. It is 20 mi (32 km) long and 5 mi (8 km) wide.  Visited in 1815 by Capt. James Kelly, it was named after Lachlan Mac�  quarie, governor of New South Wales. Its coast was the site of a penal  colony 1821-33.</p><p>Macready \m9-'kre-de\ / William (Charles) (b. March 3,1793, Lon�  don, Eng.�d. April 27, 1873, Cheltenham, Gloucestershire) English  actor-manager. He made his debut in 1810, and by 1820 he was famous  for his performances as Hamlet, Lear, and Macbeth. As theatre manager  of London�s Covent Garden (1837�39) and Drury Lane (1841^43), he  introduced reforms such as full rehearsals, historically accurate costumes  and sets, and a reversion to the original Shakespeare texts. He toured the  U.S. in 1826, 1843, and 1848-49; his last tour ended with the Astor Place  riot, caused by partisans of Edwin Forrest. He retired from the stage in  1851. His diary provides a view of 19th-century theatrical life.</p><p>macrobiotics Dietary practice based on the Chinese philosophy of bal�  ancing yin and yang (see yin-yang). It stresses avoiding foods that are  classified as strongly yin (e.g., alcoholic beverages) or yang (e.g., meat)  and relying mainly on near-neutral foods such as grains. In addition, foods</p><p>that grow naturally in one�s climate should be the mainstay of one�s diet.  Macrobiotics was first articulated in Asia in the 1930s and swept Europe  and the U.S. in the late 1960s. Adherents maintain that not only can the  quality of life be enhanced but that serious ailments such as cancer can  be healed; critics counter that uninformed attempts to practice such a diet  can lead to malnutrition.</p><p>macroeconomics Study of the entire economy in terms of the total  amount of goods and services produced, total income earned, level of  employment of productive resources, and general behaviour of prices.  Until the 1930s, most economic analysis focused on specific firms and  industries. The aftermath of the Great Depression and the development of  national income and production statistics brought new interest to the field  of macroeconomics. The goals of macroeconomic policy include economic  growth, price stability, and full employment. See also microeconomics;</p><p>NATIONAL INCOME ACCOUNTING.</p><p>macromolecule Any very large molecule, composed of much larger  numbers (hundreds or thousands) of atoms than ordinary molecules. Some  macromolecules are individual entities that cannot be subdivided without  losing their identity (e.g., certain proteins, with molecular weights into the  millions). Others (polymers) are multiples of a repeating building block  (monomer) in chains or networks (e.g., plastics, cellulose). Most macro�  molecules are in the size range typical of colloids.</p><p>macular degeneration Degeneration of the macula (central part of  the retina), with corresponding visual-field defect. It is the leading cause of  blindness in old age. Probably due to reduced blood circulation, it is now  known to have a genetic component. It is twice as common in smokers  as in nonsmokers, and it is also correlated with lifelong sun exposure.  Peripheral vision usually remains, but loss of central visual acuity makes  reading or fine work difficult or impossible, even with special magnify�  ing eyeglasses. Some forms of macular degeneration can be halted (but  not reversed) by laser surgery.</p><p>Macumba Vmo-'kum-boX Afro-Brazilian religion characterized by the  syncretism of traditional African religions, Brazilian spiritualism, and Roman  Catholicism. Of the several Macumba sects in Brazil, the most important  are Candomble and Umbanda. African elements include an outdoor cer�  emonial site, the sacrifice of animals (e.g., cocks), spirit offerings (e.g.,  candles and flowers), and dances. Macumba rites are led by mediums,  who fall prostrate in trances and communicate with holy spirits. Roman  Catholic elements include the cross and the worship of saints, who are  given African names.</p><p>Macy &amp; Co. in full R.H. Macy &amp; Co., Inc. Major U.S. department-  store chain. Its main outlet, the 11-story store that occupies a city block  in New York City�s Herald Square, was for many years the largest single  store in the country. Rowland H. Macy (18227-1877) established the  business in 1858; its red star trademark was derived from a tattoo he bore.  The Straus family acquired part interest in the company in 1887, took full  control in 1896, and expanded the business by purchasing or building  branch stores around the country. Forced into bankruptcy in 1992, Macy�s  agreed to a merger with Federated Department Stores, Inc. in 1994.</p><p>mad cow disease or bovine spongiform encephalopathy  (BSE) Vspon-ji-.form-in-.-sef-o-Tap-o-theN Fatal neurodegenerative dis�  ease of cattle. Symptoms include behavioral changes (e.g., agitation),  gradual loss of coordination and locomotive function, and, in advanced  stages, weight loss, fine muscular contractions, and abnormal gait. Brain  tissue becomes pitted with holes and spongy. Death usually follows within  a year. The disease is similar to the neurodegenerative disease of sheep  called scrapie. No treatment is known. A BSE epidemic in Britain that  began in the mid-1980s is believed to have been caused by the use of  cattle feed containing supplements made from ruminant carcasses and  trimmings. Hundreds of thousands of infected cattle were slaughtered and  the use of animal-derived protein supplements ended. The cause of both  BSE and scrapie is attributed to an infectious aberrant protein called a  prion. The unusual occurrence of Creutzfeldt-Jakob disease, another prion-  related illness, in young people beginning in the mid-1990s may be linked  to eating meat from cattle with BSE.</p><p>Madagascar officially Republic of Madagascar Country, occu�  pying the island of Madagascar, in the western Indian Ocean off the south�  east coast of Africa.

Mada�  gascar�s high central plateau rises to 9,436 ft (2,876 m) at the volcanic  Tsaratanana massif; the island was once heavily forested, and forests still  cover one-fifth of the land area. Agriculture dominates the economy;  staple crops include rice and cassava, and cash crops include coffee,  cloves, and vanilla. Madagascar is a republic with two legislative houses;  its chief of state and head of government is the president, assisted by the  prime minister. Indonesians migrated to Madagascar c. ad 700. The first  European to visit the island was Portuguese navigator Diogo Dias in 1500.  Trade in arms and slaves allowed the Malagasy kingdoms to develop at the  beginning of the 17th century. In the 18th century the Merina kingdom  became dominant; with British assistance, it gained control of a large part  of Madagascar in the early 19th century. In 1868 Merina signed a treaty  granting France commercial access to the northwestern coast, and in 1895  French troops took the island. Madagascar became a French overseas ter�  ritory in 1946. In 1958 France agreed to let the territory decide its own  fate; as the Malagasy Republic, it gained independence in 1960 and sev�  ered ties with France in the 1970s, taking its present name in 1975. A new  constitution was adopted in 1998.</p><p>Madani \'ma-da-ne\, Abbasi al- (b. 1931, Sid! TJqbah, Alg.)  Cofounder, with Ali Belhadj, of the Algerian Islamic Salvation Front (FIS).  After earning a doctorate in London, he returned to Algeria to teach at the  University of Algiers, where he became a leader of religious students. He  traveled with other itinerant preachers around the country, exchanging  ideas and preaching the outlines of a religious political movement. He was  arrested after the first round of voting in the 1991-92 legislative elections.  In 1999 he endorsed a peace agreement put forward by Algeria�s presi�  dent, Abdelaziz Bouteflika, between the FIS and the Algerian government.</p><p>Madariaga y Rojo ^ma-do-re-'a-go-e-'ro-hoV Salvador de (b.</p><p>July 23, 1886, La Coruna, Spain�d.

Madeira, the largest of the Madeira Islands, is the site of the region�s  capital, Funchal. Madeira Island is 34 mi (55 km) long and 14 mi (22 km)  wide and has deep ravines and rugged mountains. Possibly known to  ancient Phoenicians, it was rediscovered by the Portuguese navigator Joao  Gonsalves Zarco, who founded Funchal in 1421. It allegedly had the  world�s first sugarcane plantation. Its Madeira wine has been an impor�  tant export since the 17th century. Tourism is also important.</p><p>Madeira River River, western Brazil. A major tributary of the Ama�  zon River, it is formed by the junction of the Mamore and Beni rivers in  Bolivia and flows north along the border between Bolivia and Brazil.

Son of a  wealthy landowner, in 1908 he called  for honest, participatory elections  and an end to the long dictatorship  of Porfirio Diaz. Jailed for sedition  but released on bail, he incited an  armed insurrection that led to Diaz�s  resignation. He was elected president  in 1911. Handicapped by political  inexperience and excessive idealism,  he was quickly overwhelmed by  conflicting pressures from conserva�  tives and revolutionaries, and his  administration ended in personal and  national disaster when he was assas�  sinated in 1913.

Founded in 1836 and named for James Madison, it  became the capital of Wisconsin Territory the same year. It was incorpo�  rated as a village in 1846 and as a city in 1856. Steady development fol�  lowed the 1854 arrival of the railroad. Noted for its parks and wooded  lakeshore, it is the commercial centre of an agricultural region. Educa�  tional and governmental services are economically important; it is the seat  of the University of Wisconsin�s main campus.</p><p>Madison, James (b. March 16, 1751, Port Conway, Va.�d. June 28,  1836, Montpelier, Va., U.S.) Fourth president of the U.S. (1809-17). After  graduating from the College of New Jersey (now Princeton University),  he served in the Virginia state legislature (1776-80, 1784-86). At the  Constitutional Convention (1787), his Virginia, or large-state. Plan fur�  nished the Constitution�s basic framework and guiding principles, earn�  ing him the title �father of the Constitution.� To promote its ratification,  he collaborated with Alexander Hamilton and John Jay on the Federalist  papers, a series of articles on the Constitution and republican government  published in newspapers in 1787-88 (Madison wrote 29 of the 85  articles). In the U.S. House of Representatives (1789-97), he sponsored  the Bill of Rights. He split with Hamilton over the existence of an implied  congressional power to create a national bank; Madison denied such a  power, though later, as president, he requested a national bank from Con�  gress. In protest of the Alien and Sedition Acts, he drafted one of the Vir�  ginia and Kentucky Resolutions in 1798 (Thomas Jefferson drafted the other).  From 1801 to 1809 he was Jefferson�s secretary of state. Elected presi�  dent in 1808, he immediately faced the problem of British interference  with neutral U.S. merchant vessels, which Jefferson�s Embargo Act (1807)  had failed to discourage. Believing that Britain was bent on permanent  suppression of American commerce, Madison proclaimed nonintercourse  with Britain in 1810 and signed a declaration of war in 1812. During the  ensuing War of 1 81 2 (1812-14), Madison and his family were forced to  flee Washington, D.C., as advancing British troops burned the executive  mansion and other public buildings. During Madison�s second term  (1813-17) the second Bank of the United States was chartered and the first  U.S. protective tariff was imposed. He retired to his Virginia estate, Mont�  pelier, with his wife, Dolley (1768-1849), whose political acumen he had  long prized. He participated in Jefferson�s creation of the University of  Virginia, later serving as its rector (1826-36), and produced numerous  articles and letters on political topics.</p><p>Madonna In Christian art, a  depiction of the Virgin Mary.</p><p>Though often shown with the infant  Jesus, the Madonna (Italian: �My  lady�) may also be represented  alone. Byzantine art was the first to  develop a set of Madonna types�the  Madonna and child enthroned, the  Madonna as intercessor, the  Madonna nursing the child, and so  on. Western art adapted and added to  the Byzantine types during the  Middle Ages, producing images of  the Virgin that sought to inspire piety  through beauty and tenderness. In  the Renaissance and Baroque peri�  ods, the most popular image of the  Madonna foreshadowed the crucifix�  ion, showing the Virgin looking  gravely away from the playful child.</p><p>Madonna orig.

Her first hit single, �Holiday� (1983), forged an  upbeat dance-club sound that sold 70 million albums by 1991, including  Like a Virgin (1984). In music videos and in concert, she captivated fans  and scandalized critics with provocatively sexual showmanship. Ever atop  the latest trend, she incorporated TECHNO in Music (2000). Her films  include Desperately Seeking Susan (1985), Dick Tracy (1990), and Evita  (1996).

The Syrian madrasahs in Damascus  tended to follow a standardized plan: An elaborate facade led into a domed  hallway and then into a courtyard where instruction took place, with at  least one eyvan (vaulted hall) opening onto it. The madrasah at the Qalaun  Mosque in Cairo (1283-85) has a unique cruciform eyvan on the richly  carved qibla (wall facing Mecca) side and a smaller eyvan opposite.

The original town grew up around the  Moorish alcazar (castle), overlooking the Manzanares River. King  Alfonso VI captured the town from the Muslims in 1083. Philip II moved  the Spanish court to Madrid in 1561, and in 1607 Philip III made it the  official capital. It was occupied by French troops during the Napoleonic  Wars but returned to Spanish control in 1812. During the Spanish Civil  War (1936-39), Madrid was held by those loyal to the Republic.

The texts  were almost always about love; most prominent among the poets whose  works were set to music are Petrarch, Torquato Tasso, and Battista Guarini.  In Italy, Orlande de Lassus, Luca Marenzio, Don Carlo Gesualdo, and Clau�  dio Monteverdi were among the greatest of the madrigalists; Thomas Mor-  ley, Thomas Weelkes, and John Wilbye created a distinguished body of  English madrigals.</p><p>Madura \ma-'dur-3\ Dutch Madoera Island, Jawa Timur province,  Indonesia, off northeastern Java.

In early works, such as Hina-  moto Hall (1936) and the Dairen  Town Hall (1938), he tried to coun�  teract the pompous style of the Japa�  nese imperialist regime. In the 1950s  he continued to work primarily in the  Brutalist style of Le Corbusier (see  Brutalism). Buildings such as the  Educational Centre in Fukushima (1955) and the Harumi flats and the  Setagaya Community Centre, both in Tokyo (1959), reflect his efforts to  use concrete in a manner appropriate to the material. His community cen�  tres influenced Tange Kenzo, who started out in Maekawa�s office.</p><p>maenads and bacchantes Vme- I nadz...b3- , kants, bo-kan-tez\  Female followers of the Greek wine-god Dionysus. The word maenad  comes from the Greek, meaning �mad� or �demented.� During the orgi�  astic rites of Dionysus, maenads roamed the mountains and forests per�  forming frenzied, ecstatic dances, and were believed to be possessed by  the god. While under his influence they were supposed to have unusual  strength; it was said they could tear animals or people to pieces (the fate  met by Orpheus). As bacchantes they were named for Bacchus, the Roman  counterpart of Dionysus.</p><p>Maes VmasV Nicolaes (b. 1634, Dordrecht, Neth.�d. Nov. 24, 1693,  Amsterdam) Dutch painter. A native of Dordrecht, he went to Amsterdam  c. 1650 to study with Rembrandt, from whom he learned the Baroque style.  Before his return to Dordrecht in 1653 he painted a few life-size Rem-  brandtesque genre scenes. From 1655 to 1660 he painted smaller domes�  tic scenes, usually of women spinning, eavesdropping, reading the Bible,  or cooking. In 1673 he moved permanently to Amsterdam and devoted  himself to portraiture, abandoning intimacy and the deep glowing colours  characteristic of Rembrandt for elegance and cooler tones reminiscent of  Anthony Van Dyck. He was a prolific painter, and he achieved great suc�  cess with his portraits.</p><p>Maeterlinck Vma-tor-.liqkV Maurice (Polydore-Marie-  Bernard) later Comte Maeterlinck (b. Aug. 29, 1862, Ghent,  Belg.�d. May 6, 1949, Nice, France) Belgian playwright and poet. He  studied law in Ghent but soon turned to writing poems and plays. His  Pelleas et Melisande (1892), considered the masterpiece of Symbolist  drama (see Symbolist movement), was the basis of Claude Debussy�s opera  (1902). In his Symbolist plays, Maeterlinck used poetic speech, gesture,  lighting, setting, and ritual to create images that reflect his protagonists�  moods and dilemmas. His other writings include a collection of Symbol�  ist poems (. Hothouses , 1899) and plays such as Monna Vanna (1902), The</p><p>Blue Bird (1908), and The Burgomaster ofStilmonde (1918). He was also  noted for his popular treatments of scientific subjects, including The Life  of the Bee (1901) and The Intelligence of Flowers (1907). Maeterlinck  was awarded the Nobel Prize for Literature in 1911.</p><p>Maffei \ma-'fa\ I and II Two galaxies relatively close to the Milky Way  Galaxy, first detected in the late 1960s by the Italian astronomer Paolo  Maffei.

At a distance of about 10 million light-years, they  appear to be major members of one of the nearest galaxy groups outside  the Local Group.</p><p>Mafia Society of criminals of primarily Italian or Sicilian origin. The  Mafia arose in Sicily in the late Middle Ages, possibly as a secret orga�  nization to overthrow the rule of foreign conquerors. It drew its members  from the small private armies, or mafie, hired by landlords to protect their  estates. By 1900 the Mafia �families� of western Sicily controlled their  local economies. In the 1920s Benito Mussolini jailed most of the members,  but they were released by the Allies after World War II and resumed their  activities. In the 1970s their control of the heroin trade led to fierce rivalry  among the clans, followed in the 1980s by renewed governmental efforts  to imprison the Mafia leadership. In the U.S., Sicilian immigrants included  former Mafia members who set up similar criminal operations. Their  operations expanded from bootlegging in the 1920s to gambling, narcot�  ics, and prostitution, and the Mafia, or Cosa Nostra, became the largest  U.S. syndicated crime organization. About 24 Mafia groups or �families�  controlled operations in the U.S.; the heads (or �dons�) of the largest fami�  lies formed a commission whose main function was judicial and could  override a don�s authority. At the beginning of the 21st century the Mafia�s  power was greatly diminished through convictions of top officials, defec�  tions, and murderous internal disputes.

Modem magazines have roots in early printed pamphlets, broadsides,  chapbooks, and almanacs. One of the first magazines was the German  Erbauliche Monaths-Unterredungen (�Edifying Monthly Discussions�),  issued from 1663 to 1668. In the early 18th century Joseph Addison and  Richard Steele brought out the influential periodicals The Tatler and The  Spectator; other critical reviews began in the mid 1700s. By the 19th cen�  tury, magazines catering to specialized audiences had developed, includ�  ing the women�s weekly, the religious and missionary review, and the  illustrated magazine. One of the greatest benefits to magazine publishing  in the late 19th and early 20th centuries was the addition of advertise�  ments as a means of financial support. Subsequent developments included  more illustrations and vastly greater specialization. With the computer  age, magazines (�e-zines�) also became available over the Internet.</p><p>Gaius Maecenas, marble bust; in the  Palazzo dei Conservatori, Rome</p><p>AUNARI�ART RESOURCE/EB INC.</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1166 I Magdalen Islands &#x25BA; magic</p><p>Magdalen Ymag-ds-tanX Islands French Ties de la Madeleine</p><p>X.el-do-lo-mad-TenX Island group of eastern Quebec, Canada.

It was named after the type  site, La Madeleine in southwestern France. The Magdalenians lived some  11,000-17,000 years ago, at a time when reindeer, wild horses, and bison  formed large herds. They appear to have lived a semi-settled life sur�  rounded by abundant food. They killed animals with spears, snares, and  traps and lived in caves, rock shelters, and tents. Magdalenian stone tools  include blades, burins (chisel-like tools), scrapers, borers, and projectile  points. Their bone tools�often engraved with animal images�include  adzes, hammers, spearheads, harpoons, and eyed needles. Cave art in the  early period is characterized by coarse black drawings, while that of the  later period includes beautifully rendered realistic figures in polychrome,  such as those at Altamira, Spain. Magdalenian culture disappeared as the  climate warmed at the end of the fourth (Wiirm) glacial period (c. 10,000  bc) and herd animals became scarce.</p><p>Magdeburg Vmag-do-.burkV City (pop., 2002 est.: 229,755), capital of  Saxony-Anhalt state, east-central Germany.

Examples include electrons  circulating around atomic nuclei, rotating atomic nuclei, and single sub�  atomic particles with spin. On a large scale, these effects may add together,  as in iron atoms, to make magnetic compass needles and bar magnets,  which are macroscopic magnetic dipoles. The strength of a magnetic  dipole, its magnetic moment, is a measure of its ability to turn itself into  alignment with a given external magnetic field. When free to rotate, dipoles  align themselves so that their moments point predominantly in the direc�  tion of the magnetic field. The SI unit for dipole moment is the ampere-  square metre.</p><p>magnetic field Region around a magnet, electric current, or changing  electric field in which magnetic forces are observable. The field around a  permanent magnet or wire carrying a steady direct current is stationary,  while that around an alternating current or changing direct current is con�  tinuously changing. Magnetic fields are commonly represented by con�  tinuous lines of force, or magnetic flux, that emerge from north-seeking  magnetic poles and enter south-seeking poles. The density of the lines  indicates the magnitude of the field, the lines being crowded together  where the magnetic field is strong. The SI unit for magnetic flux is the  weber.</p><p>magnetic force Attraction or repulsion that arises between electrically  charged particles that are in motion. While only electric forces exist  among stationary electric charges, both electric and magnetic forces exist  among moving electric charges. The magnetic force between two mov�  ing charges is the force exerted on one charge by a magnetic field created  by the other. This force is zero if the second charge is traveling in the  direction of the magnetic field due to the first and is greatest if it travels  at right angles to the magnetic field. Magnetic force is responsible for the  action of electric motors and the attraction between magnets and iron.</p><p>magnetic permeability Relative increase or decrease in the magnetic  field inside a material compared with the magnetic field in which the  material is located. In empty space the magnetic permeability is 1, because  there is no matter to modify the field. Materials may be classified by the  value of their magnetic permeability. Diamagnetic materials (see diamag�  netism) have constant relative permeabilities of slightly less than 1. Para�  magnetic materials (see paramagnetism) have constant relative  permeabilities of slightly more than 1. The relative permeability of fer�  romagnetic materials (see ferromagnetism) increases as the magnetizing  field increases, reaches a maximum, and then decreases.

The structural and biochemical infor�  mation it provides is helpful in the diagnosis of abnormalities without the  possibly harmful effects of X rays or gamma rays. It is invaluable in detect�  ing and delineating tumours and in providing images of the brain, the  heart, and other soft-tissue organs. MRI may produce anxiety because the  patient must often lie quietly inside a narrow tube. Another disadvantage  is that it requires a longer scanning time than other computer-assisted  forms of scanning, which makes it more sensitive to motion and of less  value in scanning the chest or abdomen. However, MRI images provide  better contrast between normal and diseased tissue than those produced  by other computer-assisted imagery.</p><p>magnetism Phenomenon associated with magnetic fields, the effects of  such fields, and the motion of electric charges. Some types of magnetism  are diamagnetism, paramagnetism, ferromagnetism, and ferrimagnetism. Mag�  netic fields exert forces on moving electric charges.

Magnetite with an intrinsic magnetic  field (a natural magnet) is known as lodestone.</p><p>magneto \mag-'ne-to\ Permanent-magnet alternating generator used  mainly to produce electrical current for the ignition system in various types  of internal-combustion engines, such as aircraft, marine, tractor, and motor�  cycle engines. The main parts of a magneto are a permanent-magnet rotor,  a primary winding of a small number of turns of coarse wire, a second�  ary winding with a large number of turns of fine wire, a cam-type circuit  breaker, and a capacitor. As the rotor turns, it produces a current in the  primary winding, charging the capacitor. The cam breaks the circuit, and  the magnetic field around the primary winding collapses. The capacitor  releases its stored current into the primary winding, causing a reversed  magnetic field. The collapse and reversal of the magnetic field produce a  current in the secondary winding that is sent to the spark plugs.</p><p>magnetosphere Region around a planet (such as Earth) or a natural  satellite that possesses a magnetic field (see geomagnetic field) where mag�  netic phenomena and the high atmospheric conductivity caused by ion�  ization strongly influence the behaviour of charged particles (see electric  charge). A planet or moon�s magnetic field, like its gravitational field,  becomes weaker with distance from the body. The solar wind sweeps a  body�s magnetosphere out away from the Sun in a �tail� trailing well  beyond it.</p><p>magnitude In astronomy, the measure of the brightness of a star or  other celestial body. The brighter the object, the lower the number  assigned as a magnitude. In ancient times six magnitude classes were  used, the first containing the brightest stars (see Hipparchus). In the present</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>magnolia &#x25BA; Maharashtra I 1169</p><p>system a difference of one magnitude is defined as a ratio of brightness  of 2.512 times. Thus, a difference of five magnitudes corresponds to a  brightness ratio of 100 to 1. Apparent magnitude is an object�s brightness  as seen from Earth (e.g., -26.7 for the Sun, about -11 for the Moon).  Absolute magnitude is an object�s brightness as it would be seen at a dis�  tance of 10 parsecs (32.6 light-years; e.g., 4.8 for the Sun). See also albedo;  PHOTOMETRY.</p><p>magnolia Any of about 80 species of trees and shrubs in the genus  Magnolia , native to North and Central America, the Himalayas, and East  Asia. They are valued for their fragrant flowers and handsome leaves.  Magnolia is one of 12 genera in the family Magnoliaceae, which contains  210 species. Magnolias are among the most primitive of flowering plants;  their primitive features include long floral axes, spiral arrangement of  flower parts, and simple water-conducting cells.</p><p>Magnus II Eriksson (b. 1316, Norway�d. Dec. 1, 1374, Sweden)  King of Sweden (1319-63, as Magnus II) and Norway (1319-55, as Mag�  nus VII). Grandson of Norway�s Haakon V and nephew of the Swedish  king, Magnus became ruler of both countries. Since he spent almost all  his time in Sweden, Norwegian nobles arranged for his son Haakon�s  succession, and Magnus abdicated in 1355. He antagonized many Swed�  ish nobles, raising taxes and curbing the economic power of the church  and nobility. In 1356 he was forced to cede half his Swedish kingdom to  his son Erik, and he began making concessions to the nobility. When he  renewed his efforts to control the Swedish nobles, they deposed him.</p><p>Magnus effect Generation of a sidewise force on a spinning cylindri�  cal or spherical solid immersed in a fluid (liquid or gas) when there is  relative motion between the spinning body and the fluid. Named after  Heinrich Gustav Magnus (1802-1870), who first investigated the effect  experimentally in 1853, it is responsible for the curved trajectory of a ten�  nis or golf ball and affects the path of an artillery shell.</p><p>Magnus Pius, Sextus Pompeius See Sextus Pompeius Magnus Pius</p><p>magpie Any of several genera of long-tailed songbirds of the crow  family (Corvidae). The black-billed magpie (Pica pica) is 18 in. (45 cm)  long and strikingly pied (black-and-white), with an iridescent blue-green  tail. It is found in North Africa, across Eurasia, and in western North  America. A bird of farmlands and tree-studded open country, it eats  insects, seeds, small vertebrates, the eggs and young of other birds, and  fresh carrion. It makes a large, round nest of twigs cemented with mud,  and is known for hoarding small, bright objects. Other species (in the  genera Cyanopica, Cissa, and Urocissa) include the brilliant blue or green  magpies of Asia.</p><p>Magritte \ma-'gret\, Rene (-Francois-Ghislain) (b. Nov. 21,1898,  Lessines, Belg.�d. Aug. 15, 1967, Brussels) Belgian painter. After study  at the Belgian Academy of Fine Arts (1916-18), he designed wallpaper  and did advertising sketches until the support of a Brussels art gallery  enabled him to become a full-time painter. His early works were in the  Cubist and Futurist styles, but in 1922 he discovered the work of Gior�  gio de Chirico and embraced Surrealism with The Menaced Assassin (1927).  Certain images appear over and over again in Magritte�s works�the sea,  wide skies, the female torso, the bourgeois �little man� in a bowler hat,  rocks that hover overhead�and dislocations of space, time, and scale  were common elements in his enigmatic and illogical paintings.</p><p>Magsaysay \mag-'sl-,sl\ / Ramon (b. Aug. 31, 1907, Iba, Phil.�d.  March 17, 1957, near Cebu) President of the Philippines (1953-57). Son  of a Malay artisan, he was a schoolteacher before becoming a guerrilla  leader during World War II. In 1950, as secretary of defense, he launched  one of the most successful antiguerrilla campaigns in modern history,  against insurgents of the Hukbalahap Rebellion. He deprived them of popu�  lar support by offering peasants land and tools and insisting that the army  treat them with respect. By 1953 the Huks were no longer a threat, and  Magsaysay was elected president. His efforts at reform were frustrated by  a conservative Congress. He was killed in a plane crash before the end  of his term.</p><p>maguey See century plant</p><p>magus \'ma-gos\ Member of an ancient Persian clan specializing in cul-  tic activities. The magi were a priestly caste during the Seleucid, Parthian,  and Sasanian dynasties, and parts of the Avesta are probably derived from  them. Their priesthood is believed to have served several religions, includ�  ing Zoroastrianism. From the 1st century ad onward, the word magus in</p><p>its Syriac form ( magusai ) was applied to magicians and soothsayers,  chiefly from Babylonia. As long as the Persian empire lasted there was a  distinction between the Persian magi, credited with profound religious  knowledge, and the Babylonian magi, often considered outright impost�  ers. See also Magi.</p><p>Magyar Vmag-.yar, 'ma-Jar\ Any member of the dominant ethnic group  in Hungary. Speakers of a Finno-Ugric language, they migrated from their  early home in the region of present-day Bashkortostan in eastern Euro�  pean Russia across the southern Russian and Ukrainian steppes into the  northern Balkans in the 9th century. After collisions with neighbouring  peoples, the Magyars crossed the Carpathians and settled in the middle  basin of the Danube River in the late 9th century, subjugating Slavs and  other peoples there. Skilled and fierce horsemen, they raided deep into  the heart of Europe in the 10th century and were greatly feared until their  defeat by Otto I at the Battle of Lechfeld in 955. They adopted Christian�  ity in the 11th century under King Stephen I, the founder of Hungary, who  made the kingdom part of the European community.</p><p>Mah-jongg \,ma-'zhai]\ Game of Chinese origin usually played by four  persons with 144 domino-like tiles that are drawn and discarded until one  player secures a winning hand. The object of play is similar to that of the  rummy card games. It is probably of 19th-century origin. The name was  coined by J. P. Babcock, who introduced the game to the West after World  War I. The mah-jongg set includes a pair of dice, a quantity of tokens or  chips used for scorekeeping, and a rack for keeping tiles upright and  keeping their faces hidden from other players.</p><p>Mahabharata \mo- l ha- , ba-r3-t9\ One of the two major Sanskrit epics  of India, valued for its literary merit and its religious inspiration. It tells  of the struggle for supremacy between two groups of cousins, the Kau-  ravas and the Pandavas. Many myths and legends are woven into the  poem, along with didactic material on topics such as the proper conduct  of a warrior and the way to attain emancipation from rebirth. Together  with the second major epic, the Ramayana, it is an important source of  information about the evolution of Hinduism. Contained within the Mahab�  harata is the Bhagavadgita, Hinduism�s single most important religious  text. The sage Vyasa (fl. c. 5th century bc) is traditionally named as the  Mahabharata� s author, but he probably compiled existing material.

In The Influence of Sea  Power upon the French Revolution  and Empire, 1793-1812 (1892), he  stressed the interdependence of mili�  tary and commercial control of the  sea. Avidly read in Britain and Ger�  many, both books greatly influenced  the buildup of naval forces before  World War I.</p><p>Maharashtra V.ma-ho-'rash-troV  State (pop., 2001 prelim.: 96,752,247), west-central India. It lies on the  Arabian Sea and is bordered by the states of Gujarat, Madhya Pradesh,  Chhattisgarh, Andhra Pradesh, Karnataka, and Goa and the union territory  of Dadra and Nagar Haveli; its capital is Mumbai (Bombay). Occupying an  area of 118,800 sq mi (307,690 sq km), it covers much of the Deccan  plateau, containing the valleys of the Krishna, Bhima, and Godavari rivers.  The population is a mixture of ethnic groups; Marathi is the state lan�  guage. The region was divided into Hindu kingdoms in the 8th�13th cen�  turies; they were followed by a series of Muslim dynasties. A Maratha  kingdom ruled by 1674, and by the 18th century a Maratha empire had  been established.

Mahad Prasad Varma (b.</p><p>1911?, India) Indian religious leader, founder of Transcendental Medita�  tion (TM). He took a degree in physics before going to the Himalayas to  study the Advaita school of Vedanta religious thought with the yogi Guru  Dev for 13 years. He arrived in the U.S. in 1959, preaching the virtues  of TM; in the 1960s the Beatles were perhaps his most celebrated follow�  ers. The Maharishi (the title means �Great Sage�) returned to India in the  late 1970s and moved to The Netherlands in 1990. His organization,  which includes real estate holdings, schools, and clinics, was worth more  than $3 billion in the late 1990s.</p><p>Mahasanghika Xmo-.ha-'sorj-gi-koX Early Buddhist school in India  that anticipated the Mahayana tradition. Its emergence in the 4th century  bc, about 100 years after the Buddha�s death, represented the first major  schism in the Buddhist community. Though accounts of the second Bud�  dhist council attribute the split to a dispute over rules, later texts empha�  size differences between the Mahasanghikas and the Theravadins (see  Theravada) regarding the nature of the Buddha and sainthood. The  Mahasanghikas believed in a plurality of buddhas and held that the Bud�  dha in his earthly existence was only an apparition.</p><p>Mahathir bin Mohamad Xma-'ha-ter-bin-mo-'ha-modV in full  Datuk Seri Mahathir bin Mohamad (b. Dec. 20,1925, Alor Setar,  Kedah, Malay states) Malaysian politician, prime minister (1981-2003).  The son of a schoolmaster, Mahathir studied medicine and worked as a  government medical officer before entering parliament in 1964, where he  became a forceful advocate of policies to ensure economic success for  ethnic Malays. Once prime minister, he was reelected repeatedly; under  his leadership Malaysia achieved one of the most prosperous economies  in Southeast Asia, rising literacy rates, and increased life expectancies.  An economic downturn in the late 1990s precipitated a split between  Mahathir and his deputy prime minister, Anwar Ibrahim, whom Mahathir  dismissed in 1998; opposition to this action and other policies was sup�  pressed. Following the September 1 1 attacks of 2001 in the U.S., he offered  his support in the global war against terrorism, but he opposed the U.S.-  led invasion of Iraq in 2003 and was noted for his frequent criticisms of  the West.</p><p>Mahavira \m9- l ha- , ve-ro\ orig.

Born into the warrior caste,  he renounced the world at age 30 for  a life of extreme asceticism. He had  no possessions, not even rags to  cover his body or a bowl for alms or  food, and after 12 years he attained  kevala, the highest stage of percep�  tion. An advocate of nonviolence and  vegetarianism, he revived and reor�  ganized Jain doctrine and established  rules for its monastic order.

Though  the mahdi is not mentioned in the Qur�an and is questioned by Sunnite  theologians, he is important in ShTite doctrine. The doctrine of the mahdi  gained currency during the religious and political upheavals of early Islam  (7th-8th century) and received new emphasis in periods of crisis (e.g.,  after most of Spain was reconquered by Christians in 1212, and during  Napoleon�s invasion of Egypt). The title has been claimed by Islamic  revolutionaries, notably in North Africa (see al-MAHDl; Mahdist movement).</p><p>Mahdi, al- orig. Muhammad Ahmad ibn al-Sayyid ( Abd  Allah (b. Aug. 12, 1844�d. June 22, 1885, Omdurman, Sudan)  Sudanese religious and political leader. The son of a shipbuilder in Nubia,  he was brought up near Khartoum. After orthodox religious study, he  turned to a mystical interpretation of Islam in the Sufi tradition, joined a  religious brotherhood, and in 1870 moved to a hermitage with his dis�  ciples. In 1881 he proclaimed a divine mission to purify Islam and the  governments that defiled it, targeting the Turkish ruler of Egypt and its  dependency, Sudan. In 1885, after he defeated Charles George Gordon to  capture Khartoum, he established a theocratic state, but he died the same  year, probably of typhus. See also mahdi; Mahdist movement; Sufism.</p><p>Mahdist Vma-d9st\ movement Religious and political movement  founded by the Sudanese prophet al-MAHDi. He adopted the name al-Mahdl  (meaning �Divinely Inspired One�) because of his conviction that he had  been divinely chosen to lead a holy war (jihad) against Sudan�s Egyptian  ruling class, who he believed had deserted the Islamic faith. His uprising  began in 1881, and within four years he had conquered almost all the  territory formerly occupied by Egypt, his crowning victory being the cap�  ture of Khartoum from Gen. Charles George Gordon in 1885. Establish�  ing a new capital at Omdurman, he became head of an armed theocracy.  When he died from illness, his disciple �Abd Allah succeeded him. Fol�  lowing initial victories, �Abd Allah�s forces were gradually hunted down  by Anglo-Egyptian armies under H.H. Kitchener and almost entirely  destroyed in the Battle of Omdurman. The movement sustained a small  following through the next century, but its political import had been  destroyed.</p><p>Mahfouz \ma-'fuz\, Naguib (b. Dec. 11, 1911, Cairo, Egypt) Egyp�  tian writer. He worked in the cultural section of the Egyptian civil ser�  vice from 1934 to 1971. His major work, the Cairo Trilogy (1956-57)�  including the novels Palace Walk, Palace of Desire, and Sukkariyah �  represents a penetrating overview of 20th-century Egyptian society.  Subsequent works offer critical views of the Egyptian monarchy, colo�  nialism, and contemporary Egypt. Other well-known novels include  Midaq Alley (1947), Children of Gebelawi (1959), and Miramar (1967).  He also wrote short-story collections, more than 30 screenplays, and sev�  eral stage plays. In 1988 he became the first Arabic writer to win the Nobel  Prize for Literature.</p><p>Mahican See Mohican</p><p>Mahilyow Russian Mogilyov City (pop., 2001 est.: 361,000), east-  central Belarus, on the Dnieper (Dnyapro) River.

He wrote his first significant work, the cantata  Das Klagende Lied (1880), as he was eking out an existence by giving  lessons. In 1880 he became a conductor, and though his dictatorial man�  ner was disliked and critics found his interpretations extreme, by 1886 he  had achieved success in Prague. He also began the first of his 10 sym�  phonies (1888-1910), his main compositional legacy.

In the American Civil War he was appointed quartermaster general of the  Confederacy but served with the army of northern Virginia, rising to major  general. After the war he resumed railroading, becoming president of the  Atlantic, Mississippi, and Ohio (later Norfolk &amp; Western) Railroad  (1867). He built a political base through railroad patronage but lost con�  trol of the railroad in the 1870s. Unable to win the Democratic Party  nomination for governor (1877), he organized a coalition of African  Americans and poor whites to form a political party, the Readjusters  (1879), which succeeded in enacting reforms.

The Appalachian Mountains cross the state,  rising to 5,268 ft (1,606 m) at Mount Katahdin; Maine�s upland region  has many lakes and valleys, and its Atlantic coast is rocky and scenic.  Algonquian Indians were the earliest known inhabitants of the area. Euro�  pean settlers found the Penobscot and Passamaquoddy tribes living along  the river valleys and coasts. The French included Maine as part of the  province of Acadia in 1603, and Britain included it in territory granted to  the Plymouth Co. in 1606. During the 17th century Britain established  scattered settlements, but the area was a constant battleground until the  British conquered the French in eastern Canada in 1763. Maine was gov�  erned as a district of Massachusetts from 1652 until it was admitted as the  23rd state of the Union under the Missouri Compromise in 1820.

The earliest known Roman majus�  cule letters are in the style known as square capitals, distinguished by  downstrokes that are heavier than upstrokes and by serifs (short strokes  at right angles to the top and bottom of a letter). Square capitals were  used mainly in inscriptions on Roman imperial monuments. Rustic capi�  tals, used in books and official documents, formed a freer, more elliptical  script. Roman cursive capitals, a running-hand script used for notes and  letters, were a forerunner of the minuscule scripts that appeared later.</p><p>Makalu Vmo-ko-.liA Peak in the Himaayas, on the Nepalese-Tibetan bor�  der.

Not needed in Greek  and Roman theatre because of the use of masks, makeup was used in the  religious plays of medieval Europe, in which the angels� faces were  painted red and those of God and Christ white or gold. In Elizabethan  England, crude makeup methods included powdering the face with chalk  (to play ghosts and murderers) or blackening it with burnt cork (to play  Moors). As stage lighting improved in the 19th century, theatrical makeup  became more artistic; stick greasepaint, invented by Ludwig Leichner in  the 1860s, enabled actors to create more subtle characterizations. Stage  makeup proved too heavy for motion pictures; in 1910 Max Factor cre�  ated semiliquid greasepaint makeup suitable for early filmmaking, and in  1928 he created panchromatic makeup to keep pace with the develop�  ment of incandescent lighting and more sensitive film. Makeup was later  further modified for colour filmmaking and for television.

Known since before the 5th century bc, it occurs in tropical and  subtropical regions near swamps. The roles of the mosquito and the para�  site were proved in the early 20th century. Annual cases worldwide are  estimated at 250 million and deaths at 2 million. Malaria from different  Plasmodium species differs in severity, mortality, and geographic distri�  bution. The parasites have an extremely complex life cycle; in one stage  they develop synchronously inside red blood cells. Their mass fissions at  48- or 72-hour intervals cause attacks lasting 4-10 hours. Shaking and  chills are followed by fever of up to 105 �F (40.6 �C), with severe head�  ache and then profuse sweating as temperature returns to normal. Patients  often have anemia, spleen enlargement, and general weakness. Compli�  cations can be fatal. Malaria is diagnosed by detecting the parasites in  blood. Quinine was long used to alleviate the fevers. Synthetic drugs, such  as chloroquine, destroy the parasites in blood cells, but many strains are  now resistant. Carriers of a gene for a hemoglobinopathy have natural  resistance. Malaria prevention requires preventing mosquito bites: elimi�  nating mosquito breeding places and using insecticides or natural preda�  tors, window screens, netting, and insect repellent.

In northern Malawi the Ngonde people established a kingdom c. 1600,  and in the 18th century the Chikulamayembe state was founded. The slave  trade flourished during the 18th�19th century; Islam and Christianity  arrived in the region c. 1860. Britain established colonial authority in  1891, creating the Nyasaland Districts Protectorate. It became the British  Central Africa Protectorate in 1893 and Nyasaland in 1907. The colonies  of Northern and Southern Rhodesia and Nyasaland formed a federation  (1951-53), which was dissolved in 1963. The next year Malawi achieved  independence as a member of the British Commonwealth. In 1966 it  became a republic, with Hastings Banda as president. In 1971 he was des�  ignated president for life, and he ruled for three decades before being  defeated in multiparty presidential elections in 1994. A new constitution  was adopted in 1995.</p><p>Malawi, Lake or Lake Nyasa \nl-'a-s9\ Lake, southern Africa,  bounded on the west and south by Malawi, on the east by Mozambique,  and on the north by Tanzania. It is the southernmost and third largest of  the Great Rift Valley lakes. It is about 360 mi (580 km) long with an aver�  age width of 25 mi (40 km); it covers an area of 11,430 sq mi (29,604 sq  km). It contains Likoma Island, site of an Anglican cathedral completed  in 1911. On the heavily populated Malawi shore there are several gov�  ernment stations. The lake is fed by 14 rivers, and its sole outlet is the  Shire River. There are about 200 recorded species of fish in the lake.</p><p>Malay \ms-Ta, 'ma-,la\ Any member of an ethnic group that probably  originated in Borneo and expanded into Sumatra and the Malay Penin�  sula. They constitute more than half the population of Peninsular Malay�  sia. They are mainly a rural people, growing rice for food and rubber as  a cash crop. Heavily influenced by India, they were Hinduized before  converting to Islam in the 15th century. Their culture has also been influ�  enced by the cultures of the Thai, Javanese, and Sumatrans. Malay soci�  ety has traditionally been somewhat feudal; class distinctions are still  marked, and marriages have traditionally been arranged by parents and  governed by Islamic law.</p><p>Malay Archipelago Largest group of islands in the world, located  off the southeastern coast of Asia between the Indian and Pacific oceans.  It consists of the more than 13,000 islands of Indonesia and some 7,000  islands of the Philippines. Formerly called the East Indies, the archipelago  extends along the Equator for more than 3,800 mi (6,100 km). Principal  islands include the Greater Sunda Islands (Sumatra, Java, Borneo, and  Celebes), the Lesser Sundas, the Moluccas, New Guinea, Luzon, Mindanao,  and the Visayan Islands.</p><p>Malay \mo-Ta, 'ma-,la\ language Austronesian language with some  33 million first-language speakers in the Malay Peninsula, Sumatra,  Borneo, and other parts of Indonesia and Malaysia. Because Malay was  spoken on both sides of the Strait of Malacca, a crucial trade route  between India and China, Malay-speaking groups were drawn into inter�  national commerce centuries before European penetration of the region,  and Malay became a lingua franca in Indonesian ports, giving rise to a  range of pidgins and creoles known as Bazaar Malay (Melayu Pasar). In  20th-century Indonesia, a standardized form of Malay was adopted as the  national language, Indonesian; written in Latin letters, it is now spoken  or understood by about 70% of the population. Similar standardizations  of Malay comprise the national languages of Malaysia and Brunei. The  oldest known Malay texts are 7th-century inscriptions from southern  Sumatra in an Indie script (see Indic writing system); a continuous Malay  literary tradition did not begin until the Islamization of the Malay Pen�  insula in the 14th century.</p><p>Malay Peninsula Peninsula, Southeast Asia. Comprising the main�  land portion of Malaysia and southwestern Thailand, it occupies an area  of 70,000 sq mi (181,300 sq km), has a width of 200 mi (322 km), and  extends south for 700 mi (1,127 km) to Cape Balai, the southernmost point  of the Asian continent; the island country of Singapore lies just south  across the Johore Strait. Its central mountain range, rising to 7,175 ft  (2,187 m) at Mount Tahan, divides the peninsula lengthwise and is the  source of many rivers. Both its western and eastern coasts are exposed to  monsoons. It has large tracts of tropical rainforest and is a major producer  of rubber and tin.</p><p>Malayalam \,ma-b-'ya-bm\ language Dravidian language spoken  by more than 36 million people mainly in the Indian state of Kerala.  Malayalam is closely related to Tamil, from which it is estimated to have  separated about the 10th century ad. The earliest literary composition in  the language is from the 13th century. Like other major Dravidian lan�  guages, Malayalam has a number of regional dialects, social dialects that  reflect differences in caste and religion, and marked distinctions in for�  mal and informal usage. Literacy among Malayalam speakers is believed  to be higher than literacy among speakers of any other Indian language.</p><p>Malayan Emergency (1948-60) Period of unrest following the cre�  ation of the Federation of Malaya (precursor of Malaysia) in 1948. The  Communist Party of Malaya, which was mostly Chinese, was alarmed at  the special guarantees of rights for Malays (including the position of sul�  tans) and began a guerrilla insurgency, which was supported by only a  minority of the Chinese. British efforts to suppress the insurgency mili�  tarily were unpopular, especially their relocation of rural Chinese into  tightly controlled �New Villages�; when the British addressed political  and economic grievances, the rebels became increasingly isolated, and the  emergency ended. See also Tunku Abdul Rahman Putra Alhaj; Malayan  People's Anti-Japanese Army.</p><p>Malayan People's Anti-Japanese Army (MPAJA) Guerrilla  movement formed to oppose the Japanese occupation of Malaya (Penin�  sular Malaysia) during World War II. The British military, foreseeing a  Japanese invasion, trained small groups of Malayans as guerrilla troops;  these became the MPAJA. Members of the MPAJA, who were primarily  Chinese communists, emerged as heroes from the war and attempted to  seize power before the British military returned. Its leadership then went  underground until 1948, when they initiated the uprising called the  Malayan Emergency.</p><p>Malayo-Polynesian languages See Austronesian languages</p><p>Malaysia Country, Southeast Asia.

West Malaysia is  largely mountainous; East Malaysia has coastal plains rising to hills and  then to a mountainous core. Much of Malaysia is covered by rainforest.  Tree crops, notably rubber and palm oil, are the most important cash  crops; rice is the chief staple crop. Petroleum drilling and production and  tin mining are important, as is the manufacture of electronic products,  rubber goods, cement, and iron and steel products. Malaysia is a consti�  tutional monarchy with two legislative houses; the chief of state is the  paramount ruler, and the head of government is the prime minister.  Malaya has been inhabited for 6,000-8,000 years. Small kingdoms existed  in the 2nd-3rd century ad when adventurers from India first arrived.  Sumatran exiles founded the city-state of Malacca c. 1400, and it flour�  ished as a trading and Islamic religious centre until its capture by the Por�  tuguese in 1511. Malacca passed to the Dutch in 1641. The British  founded a settlement on Singapore Island in 1819, and by 1867 they had  established the Straits Settlements, including Malacca, Singapore, and Pen�  ang. During the late 19th century, Chinese began to migrate to Malaya.  Japan invaded Malaya in 1941 and captured Singapore in 1942. After  Japan�s defeat in 1945, opposition to British rule led to the creation of the  United Malays National Organization (UMNO) in 1946, and in 1948 the  peninsula was federated with Penang. Malaya gained independence from  Britain in 1957, and the Federation of Malaysia was established in 1963.  Its economy expanded greatly from the late 1970s, though it experienced  the regional economic slump of the mid- to late 1990s; the economy sub�  sequently recovered.</p><p>Malcolm II (b. c. 954�d. Nov. 25, 1034) King of Scotland (1005-34).  He acquired the throne after killing Kenneth III and defeating a Northum�  brian army at Carham (c. 1016). He became the first king to reign over  territory roughly equivalent to modem Scotland. He tried to eliminate  rivals to his grandson Duncan I, but Macbeth survived to challenge the  succession.</p><p>Malcolm III Canmore (b. c. 1031�d. Nov. 13, 1093, near Alnick,  Northumberland, Eng.) King of Scotland (1058-93). The son of King  Duncan I, he lived in exile in England after Macbeth murdered his father.  He defeated and killed Macbeth in 1057 and was crowned king, found�  ing a dynasty that consolidated royal power in Scotland. He gave refuge</p><p>to the Anglo-Saxon prince Edgar the Aetheling in 1066. Though he rec�  ognized William I as overlord in 1072, Malcolm made five raids into  England, during the last of which he was killed.</p><p>Malcolm X orig.

He was raised in  Michigan, where the family house  was burned by the Ku Klux Klan; his  father was later murdered and his  mother was institutionalized. He  moved to Boston, drifted into petty  crime, and was sent to prison for bur�  glary in 1946. He converted to the  Black Muslim faith (Nation of Islam)  the same year. On his release in  1952, he changed his last name to X  to signify his rejection of his �slave  name.� Soon after meeting the  Nation of Islam�s leader, Elijah  Muhammad, he became the sect�s  most effective speaker and organizer.</p><p>He spoke with bitter eloquence  against white exploitation of blacks and derided the civil rights move�  ment and integration, calling instead for black separatism, black pride,  and the use of violence for self-protection. Differences with Elijah  Muhammad prompted Malcolm to leave the Nation of Islam in 1964. A  pilgrimage to Mecca led him to acknowledge the possibility of world  brotherhood and to convert to orthodox Islam. Rival Black Muslims made  threats against his life, and he was shot to death at a rally in a Harlem  ballroom. His celebrated autobiography (1965) was written by Alex Haley  on the basis of numerous interviews conducted shortly before Malcolm�s  death.</p><p>Maldives Vmol-.devzX officially Republic of Maldives Archipelago  country, north-central Indian Ocean southwest of Sri Lanka.

All the islands are low-lying, none rising more than 6  ft (1.8 m) above sea level. The atolls have sandy beaches, lagoons, and a  luxuriant growth of coconut palms, together with breadfruit trees and  tropical bushes. One of the world�s poorest countries, the Maldives has a  developing economy based on fishing, tourism, boatbuilding, and boat  repairing. It is a republic with one legislative house; its head of state and  government is the president. The archipelago was settled in the 5th cen�  tury bc by Buddhists probably from Sri Lanka and southern India; accord�  ing to tradition, Islam was adopted in 1153. The Portuguese held sway in  Male in 1558-73. The islands were a sultanate under the Dutch rulers of  Ceylon (Sri Lanka) during the 17th century. After the British gained con�  trol of Ceylon in 1796, the area became a British protectorate, a status  formalized in 1887. The islands won full independence from Britain in  1965, and in 1968 a republic was founded and the sultanate abolished.  The Maldives joined the British Commonwealth in 1982. Its economy has  gradually improved, aided by the growth of tourism.

He joined the  Communist Party in 1920 and rose swiftly through the ranks as a close  associate of Joseph Stalin. In 1946 he became a full member of the Polit�  buro and deputy prime minister. After Stalin�s death (1953), he was forced  to yield his post as senior party secretary to Nikita Khrushchev, but as prime  minister Malenkov worked to reduce arms appropriations, increase the  production of consumer goods, and provide more incentives for collec�  tive farm workers. His programs were opposed by other party leaders,  and he was forced to resign as prime minister (1955). Involved in the  unsuccessful effort to depose Khrushchev, he was expelled from his other  posts (1957) and from the party (1961) and was exiled to central Asia to  manage a hydroelectric plant.</p><p>Malesherbes \mal-'erb\, Chretien Guillaume de Lamoignon</p><p>de (b.

As director of the press (1750-63), he allowed  publication of many works by the philosophes, including Denis Diderot�s  Encyclopedic. In 1775 he became secretary of state for the royal house�  hold and instituted prison and legal reforms, including ending the misuse  of lettres de cachet, and supported the economic reforms of the comptrol�  ler general, Anne-Robert-Jacques Turgot. He failed to win the king�s sup�  port for his projects and resigned in 1776. In the French Revolution, he  helped conduct the defense of Louis XVI (1792).

In 1915 he exhibited paintings more  abstractly geometrical than any seen before, consisting of simple geo�  metrical forms painted in a limited palette, a style he called Suprematism.  In 1917-18 he created his well-known White on White series, austere  images of a white square floating on a white background. In 1919 he  joined Marc Chagall at his revolutionary art school in Vitebsk, where he</p><p>exerted a strong influence on El Lissitzky. In the 1920s he returned to rep�  resentational painting but could not accede to the government�s demand  for Socialist Realism.

Mali�s terrain is largely flat, and in the  north its plains stretch into the Sahara. The upper Niger River basin is in the  south; nearly one-third of the total length of the Niger River flows through  Mali. Only a tiny fraction of Mali�s total land area is considered arable.  Mineral reserves, which are largely unexploited, include iron ore, bauxite,  gold, and copper. Agriculture constitutes the major economic activity.  Staple crops include millet, sorghum, com, and rice; cash crops include  cotton and peanuts. Mali is a republic with one legislative house; its chief  of state is the president, and the head of government is the prime minister.  Inhabited since prehistoric times, the region was on a trans-Saharan cara�  van route. The Malinke empire of Mali was founded in the 12th century on  the upper and middle Niger. In the 15th century the Songhai empire in the  Timbuktu-Gao region gained control. Morocco invaded the area in 1591,  and Timbuktu gradually declined in importance. In the mid-19th century  the French conquered the area, which became part of French West Africa.  In 1946 the area, known as the French Sudan, became an overseas territory  of the French Union. In 1958 it was proclaimed the Sudanese Republic,  and it joined with Senegal (1959-60) to form the Mali Federation. Senegal  seceded, and in 1960 the independent Republic of Mali was formed. The  government was overthrown by military coups in 1968 and 1991. Elec�  tions were held twice in the 1990s and again in 2002.

After taking degrees in phi�  losophy, physics, and mathematics in  Poland, Malinowski happened upon  James George Frazer�s The Golden  Bough and went to study anthropol�  ogy at the London School of Eco�  nomics and Political Science (1910�</p><p>16). Doing research in the Trobriand  Islands, he lived in a tent among the  people (see Trobriander), spoke the  vernacular fluently, recorded �texts�  freely on the scene as well as in set  interviews, and observed reactions  with an acute clinical eye. He was  thus able to present a dynamic pic�  ture of social institutions that clearly separated ideal norms from actual  behaviour and in doing so laid much of the basis for modem anthropo�  logical field research. He taught at the London School of Economics  (1922-38) and Yale University (1938-42). He wrote several works that  are now considered classics of anthropology, including Argonauts of the  Western Pacific (1922) and Magic, Science and Religion (1948).</p><p>Malla era Period of Nepal�s history when the Kathmandu Valley was  ruled by the Malla dynasty (10th�18th century).

Malle gained commercial success with The  Lovers (1958), starring Jeanne Moreau, and he became a leading figure in  the French New Wave. In The Fire Within (1963), Thief of Paris (1967),  Murmur of the Heart (1971), and Lacombe, Lucien (1973), he achieved  emotional realism and stylistic simplicity. In 1975 he moved to the U.S.,  where he directed films such as Pretty Baby (1978), Atlantic City (1980),  My Dinner with Andre (1981), Au revoir les enfants (1987), and Vanya  on 42nd Street (1994).</p><p>Mallet, Robert (b. June 3, 1810, Dublin, Ire.�d. Nov. 5, 1881, Lon�  don, Eng.) Irish civil engineer and scientific investigator. He studied at  Trinity College and in 1831 took charge of his father�s Victoria foundry,  which he expanded into the dominant foundry in Ireland. His commis�  sions included the construction of railroad terminals, the Nore viaduct,  the Fastnet Rock lighthouse, and several swivel bridges over the Shan�  non. His major innovation in bridge technology was buckled-plate floor�  ing. He built an early form of seismograph and advanced the technique  of making large castings of iron, such as heavy cannon.</p><p>Mallorca See Majorca</p><p>mallow family Family Malvaceae (order Malvales), which contains  about 95 genera of herbs, shrubs, and small trees. Mallow species occur  in all but the coldest parts of the world, but they are most numerous in  the tropics. Hairs that branch into starlike patterns commonly cover some  or most vegetative (nonflower) parts of these plants. The flowers are  regular and often showy. Cotton is the most important member of the  family economically. The green fruits of okra are edible. Many species  are valued as ornamentals, including hollyhock and rose of Sharon.</p><p>Malmo \'mal-,moe\ Port city (pop., 2000 est.: city, 259,579; metro, area,  522,857), southern Sweden, located across the Sound from Copenhagen.  Originally known as Malmhaug, it was chartered in the late 13th century.  Following its union with Sweden in 1658, it suffered an economic decline,  partly because of the loss of trade. The building of the harbour in 1775  and the arrival of the railroad after 1800 stimulated economic develop�  ment. Sweden�s third largest city, it is an important commercial centre.  Its economy is based on export products, shipbuilding, and textile manu�  factures. Its historic buildings include a 16th-century fortress, the town  hall, and the 14th-century St. Peter�s Church.</p><p>malnutrition Condition resulting from inadequate diet or from inabil�  ity to absorb or metabolize nutrients.

Even in the 16th century Malory�s identity  was unknown, but he is tentatively identified as a Welshman and knight  who was imprisoned at various times. Le Morte Darthur (completed c.  1470) was the first account of Arthurian legend in English prose. Though  based on French romances, it differs from its models in its emphasis on  the brotherhood of the knights rather than on courtly love and on the con�  flicts of loyalty that destroy the fellowship. Only one extant manuscript  predates its printing by William Caxton in 1485.</p><p>Malpighi \mal-'pe-ge\, Marcello (b. March 10, 1628, Crevalcore,  near Bologna, Papal States�d. Nov. 30, 1694, Rome) Italian physician  and biologist. In 1661 he identified the pulmonary capillary network,  proving William Harvey�s theory on blood circulation. He discovered the  taste buds and was the first to see red blood cells and realize that they  gave blood its colour. He studied subdivisions of the liver, brain, spleen,  kidneys, bone, and deeper skin layers (Malpighian layers), concluding that  even the largest organs are composed of minute glands. Malpighi also  studied insect larvae (especially the silkworm), chick embryology, and  plant anatomy, seeing an analogy between plant and animal organization.  He is regarded as the founder of microscopic anatomy and may be  regarded as the first histologist.</p><p>malpractice Negligence, misconduct, lack of ordinary skill, or breach  of duty in the performance of a professional service (e.g., in medicine)  that results in injury or loss. The plaintiff must usually demonstrate a fail�  ure by the professional to perform according to the field�s accepted stan�  dards. Physicians, lawyers, accountants, and other professionals have  increasingly been subject to malpractice suits in the U.S., causing a dra�  matic increase in malpractice insurance rates.</p><p>Malraux \mal-'ro\, Andre (-Georges) (b. Nov. 3, 1901, Paris,  France�d. Nov. 23, 1976, Paris) French novelist, art historian, and states�  man. Imprisoned at age 21 by French colonial authorities while on an  archaeological expedition in Cambodia, Malraux grew to be a fervent  anticolonialist and advocate for social change. He became involved with  revolutionary movements in Indochina and later fought in the Spanish  Civil War and with the French Resistance during World War II. He was  Charles de Gaulle�s minister of cultural affairs (1958-68). His novels,  which often draw on his experiences, include The Conquerors (1928);  Man�s Fate (1933, Prix Goncourt), his masterpiece; and Man�s Hope  (1937). After 1945 he abandoned fiction for art history and criticism; The  Voices of Silence (1951) is his major work of the period.</p><p>malt Grain product used in beverages and foods. Malt provides a basis  for fermentation and adds flavour and nutrients. It is made by steeping  grain, usually barley, in water and allowing partial germination to occur.  The flavour of beer primarily results from the malt from which it is made.  The enzymes produced within the bailey seed during germination break  down starch into malt sugar, or maltose, which is then fermented by yeast  to yield alcohol and carbon dioxide. Whiskey likewise is made with malt.</p><p>Malta Island country, south of Sicily in the Mediterranean Sea. It con�  sists of the three inhabited islands Malta (the largest), Gozo, and Comino  and the two uninhabited islets Comminotto and Filfla. Area: 122 sq mi  (315 sq km). Population (2005 est.): 404,000. Capital: Valletta. Malta�s  population, nearly all native-born, has a mixture of Italian, Arab, British,  and Phoenician heritage. Languages: Maltese, English (both official).  Religion: Christianity (predominantly Roman Catholic [official]). Cur�  rency: Maltese lira. Although about one-third of its total land area is  arable, Malta imports most of its food; tourism is its major industry. It is  a republic with one legislative house; its chief of state is the president,  and its head of government is the prime minister. Malta was inhabited as  early as 3800 bc. Although there is limited evidence of a Phoenician pres�  ence, it seems clearer that the Carthaginians had arrived in Malta by the  6th century bc, and the island came under Roman control in 218 bc. In  ad 60 St. Paul the Apostle was shipwrecked on the island and converted  the inhabitants to Christianity. It was under Byzantine rule until the Arabs  seized control in 870. In 1091 the Normans defeated the Arabs, and Malta  was ruled by a succession of feudal lords until the early 16th century. In  1530 it came under the control of the Hospitallers; Napoleon seized con-</p><p>Nadur</p><p>Ker6em Xewkiia * Q A</p><p>^ *' V\^ MEDITERRANEAN</p><p>y v- � � \ SEA</p><p>.Xewkija *Q a | a</p><p>C0MIN0</p><p>KEMMUNETT d . ....</p><p>Point Ta 1 -Anrax</p><p>Point Il-Qammieh^l^ !</p><p>Mellietia �</p><p>. #* d</p><p>Point 11-Wahx b aJD* MALTA</p><p>SlVARO 1 .-'' Gtiargtiur.

The 1802 Treaty of Amiens returned the  islands to the Hospitallers; however, the  Maltese protested and acknowledged Brit�  ish sovereignty, which was ratified in the  1814 Treaty of Paris. Malta became self-governing in 1921 but reverted  to a colonial regime in 1936. Malta was heavily bombed by Germany and  Italy during World War II, and in 1942 it received Britain�s George Cross  for �heroism and devotion,� the first time that this medal was not con�  ferred to an individual. In 1964 Malta gained independence within the  Commonwealth, and it became a republic in 1974. When its alliance with  Britain ended in 1979, Malta proclaimed its neutral status. In 2004 it  joined the European Union.</p><p>Malta, Knights of See Knights of Malta</p><p>Maltese Breed of toy dog named for the island of Malta, where it may  have originated about 2,800 years ago.

Feb. 14/17, 1766, Rookery,  near Dorking, Surrey, Eng.�d. Dec. 23, 1834, St. Catherine, near Bath,  Somerset) British economist and demographer. Born into a prosperous  family, he studied at the University of Cambridge and was elected a fellow  of Jesus College in 1793. In 1798 he published An Essay on the Principle  of Population, in which he argued that population will always tend to out�  run the food supply�that the increase of population will take place, if  unchecked, in a geometrical progression, while the means of subsistence  will increase only in an arithmetical progression. He believed population  would expand to the limit of subsistence and would be held there by fam�  ine, war, and ill health. He enlarged on his ideas in later editions of his work  (to 1826). He argued that relief measures for the poor should be strictly  limited since they tended to encourage the growth of excess population. His  theories, though largely disproven, had great influence on contemporary  social policy and on such economists as David Ricardo.</p><p>Malvinas, Islas See Falkland Isands</p><p>mamba Ymam-bsN Any of four or five species of slender, agile elapid  snakes (genus Dendroaspis, or Dendraspis ) having large scales and long</p><p>l_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1180 I Mamet &#x25BA; Mamoulian</p><p>L_</p><p>N</p><p>front teeth.

He won wide notice with Sexual  Perversity in Chicago (1974) and followed it with plays such as Ameri�  can Buffalo (1977) and Glengarry Glen Ross (1983, Pulitzer Prize). He  became known for rapid-fire dialogue studded with obscenities and for  his preoccupation with power relationships and corporate corruption.  Mamet used the rhythms and rhetoric of everyday speech to delineate  character, describe intricate relationships, and drive dramatic develop�  ment. His later plays include Speed-the-Plow (1987), Oleanna (1992), and  The Cryptogram (1994); his screenplays include The Verdict (1980) and  The Untouchables (1986). He also wrote and directed films such as House  of Games (1987) and State and Main (2000).</p><p>Mamluk Vmam-.lukV dynasty or Mamluke Vmam-o-.liflA  dynasty (1250-1517) Rulers of Syria and Egypt. The term mamluk is  an Arabic word for slave. Slave soldiers had been used in the Islamic  world since the 9th century, and they often exploited the military power  vested in them to seize control from the legitimate political authorities.  In 1250 a group of mamluk generals seized the throne of the AyyObid  dynasty on the death of the sultan Al-Malik al-Salih Ayyub (r. 1240-49).  The resulting dynasty legitimized its rule by reconstituting the caliphate  of the �Abbasid dynasty (destroyed by the Mongols in 1258) and by acting  as patrons to the rulers of Mecca and Medina. Under Mamluk rule the  remaining crusaders were expelled from the eastern Mediterranean coast,  and the Mongols were driven back from Palestine and Syria. Culturally,  historical writing and architecture flourished during their rule. A shift in  their ethnic makeup from Turkish to Circassian corresponded with their  slow decline; their failure to adopt field artillery as weapons (except in  siege waif are) contributed to their defeat by the Ottoman Empire in 1517.  They afterward remained intact as a social class, however, and continued  to exercise a high degree of political autonomy, though they were only  one of several forces influencing Egyptian political life. Their power was  finally broken by the Albanian-Egyptian officer Muhammad c Au in a mas�  sacre in 1811. See also Baybars I.</p><p>mammal Any member of the class (Mammalia) of warm-blooded ver�  tebrates having four limbs (except for some aquatic species) and distin�  guished from other chordate classes by the female�s milk-secreting glands  and the presence of hair at some stage of development. Other unique  characteristics include a jaw hinged directly to the skull, hearing through  bones in the middle ear, a muscular diaphragm separating the pectoral  and abdominal cavities, and nonnucleated mature red blood cells. Mam�  mals range in size from the tiny shrew to the enormous blue whale.  Monotremes (platypus and echidna) lay eggs; all other mammals bear live  young. Marsupial newborns complete their development outside the  womb, sometimes in a pouchlike structure. Placental mammals (see pla�  centa) are bom at a relatively advanced stage of development. The ear�</p><p>liest mammals date from the late Triassic Period (which ended 206 million  years ago); their immediate ancestors were the reptilian therapsids. For  70 million years mammals have been the dominant animals in terrestrial  ecosystems, a consequence of two principal factors: the great behavioral  adaptability provided by the ability of mammalian young to learn from  their elders (a consequence of their dependence on their mothers for nour�  ishment) and the physical adaptability to a wide range of climates and  conditions provided by their warm-bloodedness. See also carnivore; ceta�  cean; herbivore; insectivore; omnivore; primate; rodent.</p><p>mammary gland Vmam-o-reV Milk-producing gland of female mam�  mals, usually present but undeveloped and nonfunctional in males. Regu�  lated by the endocrine system, it is derived from a modification of sweat  glands. The mammary gland of a woman who has not borne children con�  sists of a conical disk of glandular tissue, encased in fat that gives the  breast its shape. The gland is made up of lobes drained by separate ducts  that meet at the nipple. Pregnancy causes the cells lining the lobes to mul�  tiply, and lactation begins in response to hormones released starting at the  time of birth. At the end of lactation, the glands return almost to their  state before pregnancy. After menopause, they atrophy and are largely  replaced by connective tissue and fat.</p><p>mammoth Any of several species (genus Mammuthus ) of extinct  elephants whose fossils have been found in Pleistocene deposits (begin�  ning 1.8 million years ago) on every continent except Australia and South  America. The woolly. Northern, or Siberian mammoth (M. primigenius)  is the best-known species because the Siberian permafrost preserved  numerous carcasses intact. Most species were about the size of modern  elephants; some were much smaller. The North American imperial mam�  moth (M. imperator) grew to a shoulder height of 14 ft (4 m). Many spe�  cies had a short, woolly undercoat and a long, coarse outer coat.  Mammoths had a high, domelike skull and small ears. Their long,  downward-pointing tusks sometimes curved over each other. Cave paint�  ings show them traveling in herds. Mammoths survived until about 10,000  years ago; hunting by humans may have been a cause of their extinction.

In 1972 a passage was discovered linking the Mam�  moth Cave and the Flint Ridge Cave System; the explored underground  passages have a combined length of some 329 mi (530 km). The caves  are inhabited by various animals that have undergone evolutionary adap�  tation to the dark, including cave crickets, blindfish, and blind crayfish.  Mummified Indian bodies, possibly of pre-Columbian origin, have been  found in the caves.</p><p>Mamore \ l ma-mo- , ra\ River River, north-central Bolivia.

August 833, Tar�  sus, Cilicia) Seventh caliph (r. 813-833) of the �Abbasid dynasty. He was  the son of the celebrated Harun al-Rashid and after his father�s death (809)  defeated his brother al-Amln in a civil war (813) to assume the caliph�  ate. Attempting to reconcile Sunnite and Shl'ite Muslims, he designated  as his heir a Shl'ite, 'All al-Rida, which failed to satisfy Shl'ite extrem�  ists and angered Sunnites. In any event, al-Ma�mun was predeceased by  his heir. He became a supporter of the Mu'taziutes, a theological school  whose opinions on such issues as the nature of God and man�s free will  were at variance with accepted doctrine and found little popular support.  His sponsorship of translations of Greek philosophical and scientific  works and his building of observatories and libraries proved a more last�  ing legacy.</p><p>Man, Isle of Island, in the Irish Sea off the northwestern coast of  England.

He grew up in New York City, where he studied  architecture, engineering, and art. With Marcel Duchamp he formed the  New York Dada group in 1917 and produced ready-mades. In 1921 he  moved to Paris and became associated with the Surrealists. He rediscov�  ered the technique for making �cameraless� pictures (photograms), which  he called �rayographs,� by placing objects on light-sensitive paper; he also  experimented with the technique of solarization, which renders part of the  image negative and part positive by exposing a print or negative to a flash  of light during development. He turned to portrait and fashion photogra�  phy and made a virtually complete record of the celebrities of Parisian  cultural life of the 1920s and �30s. He also made important contributions  as an avant-garde filmmaker in the 1920s.</p><p>mana Vma-noN Among Polynesian and Melanesian peoples, a super�  natural force or power that may be ascribed to persons, spirits, or inani�  mate objects. Mana may be either good or evil, beneficial or dangerous,  but it is not impersonal; it is never spoken of except in connection with  powerful beings or things. The term was first used in the 19th century in  the West in connection with religion, but mana is now regarded as a sym�  bolic way of expressing the special qualities attributed to persons of sta�  tus in a hierarchical society, of providing sanction for their actions, and  of explaining their failures.

The basic con�  cepts are drawn from microeconomic theory, but new tools of analysis have  been added. Statistical methods, for example, are increasingly important  in estimating current and future demand for products. The methods of  operations research and programming provide scientific criteria for maxi�  mizing profit, minimizing cost, and selecting the most profitable combi�  nation of products. Decision-making theory and game theory, which  recognize the conditions of uncertainty and imperfect knowledge under  which business managers operate, have contributed to systematic meth�  ods of assessing investment opportunities.</p><p>Managua \ma-'na-gwa\ City (pop., 1995: 864,201), capital of Nicara�  gua.

A com�  mercial and financial centre enriched by Bahrain�s oil wealth, it is linked  by causeway with the nearby island city of Muharraq. First mentioned in  Islamic chronicles c. 1345, it was taken by the Portuguese in 1521 and  by the Safavid Persians in 1602. It has been held, with brief interruptions,  by the Khallfah dynasty since 1783.

Adults are 8-15 ft (2.5-4.5 m) long and weigh up to  1,500 lbs (700 kg). Manatees live singly or in small herds and are pro�  tected by law in most areas. The manatee or its relative, the dugong, may  have given rise to the folklore of mermaids. See also sea cow.</p><p>Manaus \ma-'naus\ City (pop., 2003 est.: 1,517,500), northwestern Bra�  zil.

Lying northwest of London and east of Liverpool, it was the site of a Roman  fort (ad 78-86) but was abandoned after the 4th century. By 919 the town  of Manchester had sprung up nearby. In the 16th century it was impor�  tant in the wool trade, and with the onset of the Industrial Revolution in  the 18th century it became an important manufacturing city known for its  textile production. The world�s first modem railroad, the Liverpool and  Manchester, opened in 1830. The city was beset by urban and industrial  problems in the second half of the 20th century; thereafter it was rede�  veloped, ushering in a cultural renaissance. Its many educational institu�  tions include the University of Manchester.</p><p>Manchester City (pop., 2000: 107,006), southern New Hampshire,  U.S. Located on the Merrimack River, it is the state�s largest city. It was  settled in 1722-23 and incorporated as the town of Derryfield in 1751.  One of America�s first textile mills was built there in 1805, beginning a  period of rapid industrial growth. Renamed Manchester in 1810, it was  incorporated as a city in 1846. Canal systems built in the early 19th cen�  tury opened navigation to Boston. The textile industry�s decline in the  1930s spurred industrial diversification. It is the seat of St. Anselm Col�  lege, Notre Dame College, and New Hampshire College.</p><p>Manchester, (Victoria) University of Public university in  Manchester, England. It has its origins in a nonsectarian college for men  founded in 1851. It became a university in 1880, having established col�  leges in Leeds and Liverpool which later (1903) became universities in  their own right. Ernest Rutherford conducted important research on atomic  physics at Manchester, and one of the first modem computers was built  there in the late 1940s. The university grants undergraduate and advanced  academic and professional degrees in a broad range of subjects.</p><p>Manchester school Political and economic school of thought led by  Richard Cobden and John Bright that originated in meetings of the  Manchester Chamber of Commerce in 1820 and dominated the British  Liberal Party in the mid-19th century. Its followers believed in laissez-faire  economic policies, including free trade, free competition, and freedom of  contract, and were isolationist in foreign affairs. Its adherents tended to  be businessmen, not theorists.</p><p>Manchu People, many of Juchen ancestry, who acquired a Manchu iden�  tity in the 17th century before conquering China and forming the Qing  dynasty (1644-1911/12). Though official policy aimed to maintain the  Manchus as a distinct people, this did not prevent considerable intermar�  riage and adoption of Chinese customs in areas of maximum contact with  Chinese. China today recognizes the Manchu as a distinct ethnic group  with over 10 million members living mainly in northeastern China.</p><p>Manchu dynasty See Qing dynasty</p><p>Manchu-Tungus V.man-'chii-tuq-'guzX languages or Tungusic  languages Family of about 10 Altaic languages spoken by fewer than  55,000 people in Siberia, Mongolia, and northern China. All the languages  have been losing ground for centuries as their speakers switch to the lan�  guages of surrounding populations�Russian and Yakut in Siberia, and  Chinese, Turkic, and Mongolian languages in China. Evenki has about  10,000 speakers in Siberia and far northeastern China. Even has fewer</p><p>than 6,000 speakers in northeastern Siberia and the Kamchatka Peninsula.  Nanai has fewer than 7,000 speakers near the lower Amur River. Juchen,  the tribal language of the founders of the Juchen dynasty, is now extinct,  and Manchu is spoken by fewer than 100 people, though some 10 mil�  lion inhabitants of northeastern China count themselves as ethnically  Manchu. Effectively a dialect of Manchu is Xibe, spoken by 10,000  descendants of Manchu-speaking soldiers garrisoned at 18th-century mili�  tary outposts.</p><p>Manchukuo Vman-'chii-'gwoX or Manchuguo Puppet state created  in 1932 by Japan out of the three historic provinces of Manchuria. After  the Russo-Japanese War (1895), Japan gained control of the Russian-built  South Manchurian Railway, and its army established a presence in the  area; expansion in Manchuria was seen as necessary for Japan�s status as  an emerging world power. In 1931 the Japanese army created an excuse  to attack Chinese troops there, and in 1932 Manchukuo was proclaimed  an independent state. The last Qing emperor was brought out of retire�  ment and made Manchukuo�s ruler, but the state was actually rigidly con�  trolled by the Japanese, who used it as their base for expansion into Asia.  An underground guerrilla movement composed of Manchurian soldiers,  armed civilians, and Chinese communists opposed the occupying Japa�  nese, many of whom had come over to settle in the new colony. After  Japan�s defeat in 1945 the settlers were repatriated.</p><p>Manchuria \man-'chur-e-o\ or Northeast Chinese Dongbei or</p><p>Tung-pei \'duq-'ba\ Historical region, northeastern China. It consists of  the modem provinces of Liaoning, Jilin, and Heilongjiang; the northeast�  ern portion of Inner Mongolia autonomous region is sometimes also  included. Throughout the early Chinese dynasties, China had only limited  control over Manchuria. In 1211 Genghis Khan invaded and occupied  Manchuria. Chinese rebellions overthrew the Yuan dynasty of the Mon�  gols in 1368, and the Ming dynasty was established. The Qing (Manchu)  dynasty originated there (early 17th century) and eventually spread over  China. Russia and Japan fought each other for a foothold in the region  during the Russo-Japanese War (1904-05); after its defeat, Russia ceded  southern Manchuria to Japan. The Japanese occupied all of Manchuria in  1931 and created the puppet state of Manchukuo in 1932. The Soviets  captured Manchuria in 1945, and Chinese communist guerrillas soon  came to power. In 1953 Beijing divided the region into its three current  provinces. It is now one of China�s most important industrial areas.</p><p>Mancini, Henry orig. Enrico Nicola Mancini (b.

He first gained wide attention with his jazz-inflected music for the  television series Peter Gunn (1958), but he is perhaps best known for his  humorous scores for Blake Edwards�s Pink Panther movies. He worked  extensively with Edwards throughout his career. He wrote scores for more  than 80 films and won four Academy Awards for two songs��Moon  River� and �Days of Wine and Roses��and for the film scores for Break�  fast at Tiffany�s (1961) and Victor/Victoria (1982).

Nieces of Jules Cardinal Mazarin, they moved  to France at an early age. Laure Mancini, duchess de Mercoeur (1636�  57), married Louis de Vendome, duke de Mercoeur and grandson of King  Henry IV. Olympe Mancini, countess de Soissons (1639-1708), was a  mistress of Louis XIV. She was involved with her sister, Marie Anne, in  the notorious �Affair of the Poisons� and was also accused of poisoning  her husband; she was the mother of Prince Eugene of Savoy. Marie Man�  cini, princess de Colonna (1640-1715), was also a mistress of Louis XIV;  Mazarin intrigued to prevent their marriage, and she spent most of her  life in Spain. Hortense Mancini, duchess de Mazarin (1646-99), married  Armand Charles de la Porte, who assumed the Mazarin title. After leav�  ing her husband, she became a famous beauty at the English court of  Charles II.

Mandalas may be painted on paper or cloth, drawn on the  ground, or fashioned of bronze or stone. Two types of mandalas repre�  sent different aspects of the universe: the garbha-dhatu (�womb world�),  in which the movement is from one to the many, and the vajra-dhatu  (�diamond world�), from the many into one.</p><p>Mandalay City (pop., 2004 est.: 1,176,900), central Myanmar (Burma).

The last capital of the Myanmar kingdom, it fell to Britain  in 1885. It was nearly destroyed during the Japanese occupation in World  War II. An important Buddhist religious centre, it is the site of the famous  Mahamuni pagoda and of 730 pagodas that house marble tablets inscribed  with Buddhist scriptures.</p><p>Mandan \'man-,dan\ North American Plains Indian people living mostly  in North Dakota, U.S. Their name is probably of French derivation. The  Mandan language, which is Siouan, is nearly extinct. The Mandan, who  lived in dome-shaped, earth-covered lodges clustered in stockaded vil�  lages, planted corn, beans, pumpkins, and sunflowers, hunted buffalo, and  made pottery and baskets. They held elaborate ceremonies, including the  sun dance and the bear ceremony, a healing and war-preparation rite. They  had age-graded warrior societies as well as shamanistic and women�s  societies. Artists depicted heroic deeds on buffalo robes. George Catlin  portrayed Mandan life and people in a series of paintings. According to  him, they called themselves Seepohskahnumahkahkee, meaning �People  of the Pheasant.� By the mid-19th century the Mandan, reduced by small�  pox, were removed to North Dakota�s Fort Berthold Reservation, where  they live with the Hidatsa and the Arikara as the Three Affiliated Tribes.  Some 350 people claimed sole Mandan descent in the 2000 U.S. census.</p><p>Mandarin In imperial China, a public official drawn from the ranks of  the lesser officeholders who had achieved success in the Chinese examina�  tion system. The word comes from the Portuguese version of the Malay  term for a minister of state.

Substantial numbers are also found in Guinea-  Bissau, Guinea, and Burkina Faso; and there are very much smaller, iso�  lated pockets in the region. The most significant subgroup is the  Mandekan complex�a continuum of languages and dialects, including  those spoken by the Bambara, Malinke, Maninka, and Dyula�spoken from  Senegal, The Gambia, and Guinea east through Mali to Burkina Faso.  Mande, spoken in Sierra Leone, also has more than a million speakers.  Several independent writing systems based on the syllable were devel�  oped by speakers of Mande languages.

It is played with a plec�  trum; each pair of strings is strummed rapidly back and forth to produce  a characteristic tremolo.</p><p>mandrake Any of six plant species of the genus Mandragora (night�  shade family), native to the Mediterranean and the Himalayas. The best-  known species, M. officinarum, has a short stem bearing a tuft of ovate  flowers, with a thick, fleshy, often forked root. The mandrake has long  been known for its poisonous properties. In ancient times it was used as  a narcotic and an aphrodisiac, and it was believed to have magical pow�  ers. When pulled from the ground, its forked root, supposed to resemble  the human form, was said to utter a shriek that killed or drove mad any�  one who heard it. Once pulled, however, the plant was said to provide  soothing sleep, heal wounds, induce love, and facilitate pregnancy. In  North America, the name �mandrake� is often used for the mayapple  {Podophyllum peltatum ), a spring forest wildflower.</p><p>mandrill Diurnal monkey (family Cercopithecidae, usually genus Man-  drillus ) of equatorial African rainfor�  ests, known for its striking  colouring.

After  having a few paintings accepted by the Salon, in 1863 the jury of the Salon  rejected his Dejeuner sur I�herbe, and so Manet instead exhibited it at the  Salon des Refuses (established to exhibit the many works rejected by the  official Salon). This large canvas aroused loud disapproval from critics,  who were offended by the presence of a naked woman in the company of  two young men clothed in contemporary dress. At the Salon of 1865, his  painting Olympia, created two years earlier, also caused a scandal: the  painting�s reclining female nude gazes brazenly at the viewer and is  depicted in a harsh, brilliant light that obliterates traditional modeling and  turns her into an almost two-dimensional figure.

In 1882 he created the paint�  ing A Bar at the Folies-Bergere (1882), a daring, controversial composition  that was radical in its obliteration of the boundary between the viewer and  what is viewed. The critical resistance to Manet�s work did not abate until  near the end of his career; it was not until the 20th century that his repu�  tation was secured by art historians and critics.

It is a silvery  white, hard, brittle metal, widely distributed in Earth�s crust in combina�  tion with other elements. Nodules rich in manganese occur in huge quan�  tities on the seafloor, but no economical way to mine them has been  devised. More than 95% of the manganese produced is used in iron and  steel alloys and much of the rest in nonferrous aluminum and magnesium  alloys to improve their corrosion resistance and mechanical properties.  Manganese compounds, in which it has various valences, are used in fer�  tilizers and textile printing and as reagents and raw materials. Potassium  permanganate is used for disinfecting, deodorizing, and bleaching and as  a reagent in analysis. Manganese is essential to plants for growth and to  higher animals to promote the action of many enzymes.</p><p>mango Evergreen tree and fruit {Mangifera indica ) of the sumac, or  cashew, family, one of the most important and widely cultivated fruits of  the tropical world.

The term also applies to the thickets and forests of such  plants. Mangroves characteristically have prop roots (exposed, support�  ing roots). In addition, in many species respiratory, or knee, roots project  above the mud and have small openings through which air enters, pass�  ing through the soft, spongy tissue to the roots beneath the mud. Man�  grove fruits put out an embryonic root before they fall from the tree; the  root may fix itself in the mud before the fruit separates from the parent.  Likewise, branches and trunks put out adventitious roots which, once they  are secure in the mud, send up new shoots. The common mangrove  (Rhizophora mangle) grows to about 30 ft (9 m) tall and bears short, thick,  leathery leaves on short stems, and pale-yellow flowers.

Among its many points of interest are Central Park, the Empire  State Building, the site of the former World Trade Center, the United Nations  headquarters, Wall Street, the Metropolitan Museum of Art, the Museum of  Modern Art, Lincoln Center for the Performing Arts, Carnegie Hall, Colum�  bia University, the Juiluard School, and New York University.</p><p>Manhattan Project (1942-45) U.S. government research project that  produced the first atomic bomb. In 1939 U.S. scientists urged Pres. Fran�  klin D. Roosevelt to establish a program to study the potential military use  of fission, and $6,000 was appropriated. By 1942 the project was code-  named Manhattan, after the site of Columbia University, where much of  the early research was done. Research also was carried out at the Univer�  sity of California and the University of Chicago. In 1943 a laboratory to  construct the bomb was established at Los Alamos, N.M., and staffed by  scientists headed by J. Robert Oppenheimer. Production also was carried out  at Oak Ridge, Tenn., and Hanford, Wash. The first bomb was exploded  in a test at Alamogordo air base in southern New Mexico. By its end the  project had cost some $2 billion and had involved 125,000 people.</p><p>Mani \ma-'ne\ or Manes \ma-'ne, 'ma-nez\ or Manichaeus  V.ma-no-'ke-osV (b.

He had his first vision of an angel  in his boyhood, and when he was 24 the angel reappeared and called him  to preach a new religion. He traveled to India and made converts there.  The Persian king Shapur I permitted him to preach in the Persian empire,  but, during the reign of Bahram I, Mani was attacked by Zoroastrian  priests. After a 26-day trial he was sentenced to prison, where he died.</p><p>manic-depressive psychosis See bipolar disorder</p><p>Manichaeism Vma-no-.ke-.i-zom, .ma-no-'ke-.i-zoirA Dualistic religion  founded by Mani in Persia in the 3rd century ad. Inspired by a vision of  an angel, Mani viewed himself as the last in a line of prophets that  included Adam, Buddha, Zoroaster, and Jesus. His writings, now mostly  lost, formed the Manichaean scriptures. Manichaeism held that the world  was a fusion of spirit and matter, the original principles of good and evil,  and that the fallen soul was trapped in the evil, material world and could  reach the transcendent world only by way of the spirit. Zealous mission�  aries spread its doctrine through the Roman empire and the East. Vigor�  ously attacked by both the Christian church and the Roman state, it  disappeared almost entirely from Western Europe by the end of the 5th  century but survived in Asia until the 14th century.

Located on Luzon island on the eastern shore of Mania  Bay, it is the chief port and the economic, political, and cultural centre of  the Philippines. The walled Muslim settlement originally built on the site  was destroyed by Spanish conquistadors, who founded the fortress city  of Intramuros in 1571. It was briefly held by the British (1762-63) dur�  ing the Seven Years' War. During the Spanish-American War, U.S. forces  gained control of Manila in 1898. Occupied by the Japanese in 1942, it  was widely damaged during the fight for its recapture by U.S. forces in  1945. In 1946 it became the capital of the newly independent Republic  of the Philippines, and was rebuilt. Quezon City became the capital in  1948, but Manila regained that position in 1976. In addition to its diver�  sified industries, including shipbuilding and food processing, it is the seat  of several universities.</p><p>Manila Bay Inlet of the South China Sea extending into southwestern  Luzon island, Philippines. Considered one of the world�s great harbours,  it forms a nearly landlocked body of water with an area of 770 sq mi  (2,000 sq km). It measures 36 mi (58 km) across at its widest point. The  decisive Battle of Mania Bay, in the Spanish-American War, took place  there in 1898. The Japanese gained control of the bay in 1942 during  World War II, but it was recaptured by U.S. forces in 1945. Corregidor  Island, the scene of intense fighting in the war, divides the bay�s entrance  into the South Channel and the North Channel.</p><p>Manila Bay, Battle of (May 1, 1898) Naval engagement in the  Spanish-American War. The U.S. Asiatic Squadron under George Dewey  was ordered to sail from its Hong Kong base to destroy the Spanish fleet  then in the Philippines. In one morning the guns of Dewey�s squadron  completely destroyed the Spanish ships anchored in Manila Bay. The  Spanish suffered 381 casualties, the Americans fewer than 10. Manila later  surrendered and was occupied by U.S. troops in August. The battle estab�  lished the U.S. as a major naval power.</p><p>Manin \ma-�nen\, Daniele (b. May 13, 1804, Venice�d.

He was freed following the rebel�  lion that year and became president of the Venetian republic, reluctantly  accepting union with the kingdom of Piedmont-Sardinia in the name of  Italian unification. He led a heroic defense of Venice against an Austrian  siege, but he was forced to surrender in 1849. Banished, he lived in Paris  the rest of his life, but in 1868 his body was returned to liberated Venice  for a state funeral.</p><p>manioc See cassava</p><p>Manipur Vmo-ni-.pCuA State (pop., 2001 prelim.: 2,388,634), northeast�  ern India.

It is bounded by Nunavut, Hudson Bay, Ontario, Saskatchewan,  and by the U.S.; its capital is Winnipeg. Three-fifths of its territory is cov�  ered by the Canadian Shield, an area of rocks, forests, and rivers. The  region was first inhabited by the Inuit (Eskimo) and by the Cree, Assiniboin,  and Ojibwa peoples. The Hudson's Bay Co. opened Manitoba to European  influence, and the region became a focus of French and British compe�  tition for Canadian fur trade dominance; it was ceded by France to Brit�  ain in 1763. The Metis rebellion led to the passage of the Manitoba Act  in 1870, making it the fifth province of the Dominion of Canada. Steam�  boat and rail transportation opened the province to settlers from Europe  in the late 19th century. Though much of the economy is based on farm�  ing, lumbering, and mining, heavy industry has become important to an  expanding Winnipeg.</p><p>Manitoba, Lake Lake, south-central Manitoba, Canada.

All About Eve (1950, Academy  Awards for best picture, director, and screenplay), and The Barefoot Con-  tessa (1954), and directed Julius Caesar (1953), Suddenly Last Summer  (1959), and the disastrously expensive Cleopatra (1963). His older  brother, Herman (1897-1953), was a screenwriter and a famous wit, best  remembered as the principal author of Citizen Kane (1941, Academy  Award).</p><p>Manley, Michael (Norman) (b. Dec. 10, 1924, St. Andrew,  Jam.�d. March 6, 1997, Kingston) Jamaican political leader. Son of a  prime minister of Jamaica and a sculptor, Manley was a leader of the Peo�  ple�s National Party and the National Worker�s Union before becoming  prime minister in 1972. His leftist government made significant improve�  ments in housing, education, and health care, but a dramatic rise in oil  prices precipitated an economic crisis. Much of the middle class fled the  country, unemployment rose to 30%, and violence broke out in the run-up  to the 1980 election, in which he was defeated. He was reelected in 1989,  this time as a moderate; he stepped down in 1992 for health reasons.</p><p>Mann, Horace (b. May 4, 1796, Franklin, Mass., U.S.�d. Aug. 2,  1859, Yellow Springs, Ohio) U.S.  educator, the first great American  advocate of public education. Raised  in poverty, Mann educated himself at  the Franklin, Mass., town library and  gained admission to Brown Univer�  sity. He later studied law and was  elected to the state legislature. As  state secretary of education he vig�  orously espoused educational  reform, arguing that in a democratic  society education should be free and  universal, nonsectarian, and reliant  on well-trained, professional teach�  ers. In his later years he served in the  U.S. Congress (1848-53) and as first  president of Antioch College, (1853�</p><p>59) and he worked resolutely to end  SLAVERY.</p><p>Mann Vman\, Thomas (b. June 6,</p><p>1875, Liibeck, Ger.�d. Aug. 12,</p><p>1955, near Zurich, Switz.) German novelist and essayist, considered the  greatest German novelist of the 20th century. After a brief period of office  work, Mann devoted himself to writing, as had his elder brother Heinrich  (1871-1950). Buddenbrooks (1901), his first novel, was an elegy for old  bourgeois virtues. In the novella Death in Venice (1912), a sombre mas�  terpiece, he took up the tragic dilemma of the artist in a collapsing soci�  ety. Though ardently patriotic at the start of World War I, after 1919 he  slowly revised his views of the authoritarian German state. His great novel  The Magic Mountain (1924) clarified his growing espousal of Enlighten�  ment principles as one strand of a complex and multifaceted whole. An  outspoken opponent of Nazism, he fled to Switzerland on Adolf Hitler�s  accession; he settled in the U.S. in 1938 but returned to Switzerland in  1952. His tetralogy Joseph and His Brothers (1933-43) concerns the bib�  lical Joseph. Doctor Faustus (1947), his most directly political novel,  analyzes the darker aspects of the German soul. The often hilarious Felix  Krull, Confidence Man (1954) remained unfinished. He is noted for his  finely wrought style enriched by humour, irony, and parody and for his  subtle, many-layered narratives of vast intellectual scope. His essays  examined such figures as Leo Tolstoy, Sigmund Freud, Johann Wolfgang  von Goethe, Friedrich Nietzsche, Anton Chekhov, and Friedrich Schiller. He  received the Nobel Prize for Literature in 1929.</p><p>Mannerheim Vma-nor-.hamV, Carl Gustaf (Emil) (b. June 4, 1867,  Villnas, Fin.�d. Jan. 27, 1951, Lausanne, Switz.)

A career officer in the Russian imperial  army (1889-1917), he commanded the anti-Bolshevik forces (1918) in  the Finnish Civil War and expelled the Soviet forces. He served as regent  of Finland (1918-19) until the new republic was declared. As chairman  of the national defense council (1931-39) he oversaw construction of the  Mannerheim line of fortifications across the Karelian Isthmus. As com�  mander in chief of Finnish forces (1939-40, 1941�44), he won initial  successes against greatly superior Soviet forces in the Russo-Finnish War  (1939-40). Named president of the Finnish republic in 1944, he negoti�  ated a peace agreement with the Soviets.</p><p>Mannerism Artistic style that predominated in Italy from the end of  the High Renaissance in the 1520s to the beginnings of the Baroque period  c. 1590.

The  deep, linear perspectival space of High Renaissance painting is flattened  and obscured so that the figures appear as a decorative arrangement of  forms in front of a flat background of indeterminate dimensions. Man�  nerists sought a continuous refinement of form and concept, pushing exag�  geration and contrast to great limits. After being superseded by the  Baroque style, it was seen as decadent and degenerative. By the 20th cen�  tury it was appreciated anew for its technical bravura and elegance. Major  artists who practiced the style include Parmigianino, Federico Zuccaro, and  II Bronzino.</p><p>Mannheim City (pop., 2002: city, 308,385; metro, area, 1,568,679),  southwestern Germany.

It was a village in the  8th century, fortified by Elector Frederick IV, and chartered in 1607. The  town was twice destroyed in wars during the 17th century and was rebuilt  when the Palatine electors (see Palatinate) moved their residence there in  1720.

A  member of the Oxford movement, he became a Catholic in 1851 and was  ordained a priest later that year. He rose rapidly in rank, being appointed  archbishop of Westminster in 1865 and cardinal in 1875. He favoured the  centralization of authority in the church (Ultramontanism) and supported  stronger wording on papal infallibility than was eventually adopted by the  First Vatican Council. He established many schools and was highly  regarded for his concern for social welfare.</p><p>manorialism or seignorialism Vsan-'yor-e-ol-i-zomV Political, eco�  nomic, and social system by which the peasants of medieval Europe were  tied to their land and their lord through serfdom. The basic unit was the  manor, a self-sufficient landed estate, or fief, under the control of a lord.  Free tenants paid rent or provided military service in exchange for the use  of the land. Peasants farmed small plots of land and owed rent and labor  to their lord, and most were not free to leave the estate. The manorial  system was flourishing in Western Europe by the 8th century and had  begun to decline by the 13th century, while in Eastern Europe it achieved  its greatest strength after the 15th century.</p><p>Mansa Musa See Musa</p><p>Mansfield, Katherine orig.</p><p>Kathleen Mansfield Beau�  champ (b.

As chief justice of the King�s  Bench (1756-88), he conducted several scrupulously fair trials of persons  accused of treason and seditious libel. He reduced an unwieldy mass of  outmoded commercial law to a coherent body of rules, refined the law of  contracts, and made major contributions to maritime law. He was a mem�  ber of the cabinet three times, entrusting the great seal of his office to a  committee so that he could retain the chief justiceship and still exert  political power.

By  1968, he had become the leader of the �Family,� a communal religious  cult in Los Angeles dedicated to studying and implementing his eccen�  tric religious teachings. In 1969 he sent Family members to a house rented  by the actress Sharon Tate and her husband Roman Polanski; there they  murdered Tate and five friends, and elsewhere they killed three others.  The trials of Manson and four of his followers in 1971 attracted national  attention. Their death sentences were commuted to life imprisonment  when California abolished the death penalty in 1972.

At about 17 he established his own workshop and  received an important commission for an altarpiece, now lost. His fres�  coes in Padua�s Eremitani Church (1448-57), with their monumental fig�  ures and detailed treatment of Classical architecture, show that he had  fully mastered perspective and foreshortening and was successfully  experimenting with illusionistic effects, best seen in his frescoes of the  Gonzaga family (completed 1474) in the Palazzo Ducale�s Camera degli  Sposi (Bridal Chamber) in Mantua, which transform the small interior  room into an open-air pavilion. He was the first artist in northern Italy to  work fully in the Renaissance style. He married a daughter of the Bellini  family in 1453 but did not join the Bellini studio. He later became court  painter to Ludovico Gonzaga. His humanistic approach to antiquity and  his spatial illusionism were to have far-reaching influence.</p><p>Mantineia V.man-to-'m-oX or Mantinea Ancient Greek city of Arca�  dia, situated north of modern Tripolis.

Between 1954 and 1961  �the Mick� led the American League four times in home runs, six times  in runs, and once in RBIs, the latter occurring in the year (1956) that he  won the triple crown for home runs, RBI, and batting average (.353). In  1961 he hit 54 home runs, finishing second in the home-run race behind  his teammate Roger Maris, who broke Babe Ruth�s season record that same  year. Mantle had to play with his legs heavily taped for much of his career  because of injuries to his ankles and knees. He retired in 1968 with a  lifetime total of 536 home runs.</p><p>mantra In Hinduism and Buddhism, a sacred utterance (syllable, word, or  verse) believed to possess mystical or spiritual power. Mantras may be  spoken aloud or uttered in thought, and they may be either repeated or  sounded only once. Most have no apparent verbal meaning, but they are  thought to have profound significance and to serve as distillations of  spiritual wisdom. Repetition of a mantra can induce a trancelike state and  can lead the participant to a higher level of spiritual awareness. Widely  used mantras include om in Hinduism and om mani padme hum in Tibetan  Buddhism.</p><p>Manu Vmo-niA In the mythology of India, the first man and the legend�  ary author of the Manu-smrti. Manu appears in the Vedas as the performer  of the first sacrifice. He is also known as the first king, and most rulers  of medieval India claimed him as an ancestor. In the story of the great  flood, Manu combines the characteristics of Noah and Adam. He built a  boat after being warned of the flood by a fish. His boat came to rest on a  mountaintop, and as the flood receded Manu poured out an oblation of  milk and butter. A year later a woman calling herself the �daughter of  Manu� was born from the waters, and these two became the parents of a  new human race to replenish the earth.</p><p>Manu-smrti Vmo-nii-'smri-teV officially Manava-dharma-  shastra Most authoritative of the books of the Hindu law code  {Dharma-shastra). It is attributed to the legendary first man and lawgiver,  Manu. In its present form it dates from the 1st century bc. It prescribes  the dharma of each Hindu, stating the obligations attached to his or her  social class and stage of life. Making no distinction between religious and  secular law, it deals with cosmogony, sacraments, and other religious top�  ics as well as with marriage, hospitality, dietary restrictions, the conduct  of women, and the law of kings.</p><p>Manual of Discipline or Rule of the Community Major docu�  ment produced by the Essene community of Jews.

May 31,</p><p>1469, Alcochete, Port.�d. December 1521, Lisbon) King of Portugal  (1495-1521). He opened trade with India and Brazil, sending Pedro Alva-  res Cabral on a voyage to East Asia (1500), and gained riches from Vasco  da Gama�s voyage around Africa. Manuel�s claims to the newly discov�  ered lands were confirmed by the pope and recognized by Spain. In order  to marry the daughter of Ferdinand V and Isabella, he agreed to expel Jews  and Muslims from Portugal (1496). His reign saw the founding of Por�  tuguese outposts in India and the Malay Peninsula, and his explorers</p><p>reached China in 1513. Manuel also centralized Portuguese administra�  tion, reformed the courts, and revised the legal code.</p><p>Manuel I Comnenus \ , man-yu-ol...kam- , ne-n9s\ (b. Nov. 28,  1118�d. Sept. 24, 1180) Byzantine emperor (1143-80). The son of John  II Comnenus, he renewed alliances in the West against the Normans in Sic�  ily and Antioch. He took Apulia briefly (1155) but was defeated at Brin�  disi (1156) by a joint force of Germans, Venetians, and Normans, ending  Byzantine control in Italy. He reasserted his authority over the Crusader  states (1158-59) and extended his influence among the Hungarians and  Serbs, adding Dalmatia, Croatia, and Bosnia to the empire in 1167. He  launched a campaign against the Seljuq Turks (1176), and his defeat  showed the waning of Byzantine power and ended his plan of restoring  the Roman Empire.</p><p>Manuel II Palaeologus \ , man-yu-3l...,pa-le- , a-l9-g9s\ (b. July 27,  1350�d. July 21, 1425) Byzantine emperor (1391-1425). He was  crowned coemperor with his father, John V Palaeologus, in 1373; his  brother Andronicus IV seized the throne in 1376, but Manuel and his  father regained it with Turkish aid in 1379. They were obliged to pay trib�  ute to the sultan, who later helped them quash a rebellion by Androni�  cus�s son (1390). Manuel was forced to live as a vassal at the Turkish  court but escaped after his father�s death (1391). A treaty in 1403 kept  peace with the Turks until 1421, when Manuel�s son and coemperor John  VIII meddled in Turkish affairs. After the Turks besieged Constantinople  (1422) and took southern Greece (1423), Manuel signed a humiliating  treaty and entered a monastery.</p><p>manufacturing Any industry that makes products from raw materials  by the use of manual labour or machines and that is usually carried out  systematically with a division of labour. In a more limited sense, manu�  facturing is the fabrication or assembly of components into finished prod�  ucts on a fairly large scale. Among the most important manufacturing  industries are those that produce aircraft, automobiles, chemicals, cloth�  ing, computers, consumer electronics, electrical equipment, furniture,  heavy machinery, refined petroleum products, ships, steel, and tools. See  also factory; mass production.</p><p>manure Organic material that is used to fertilize land, usually consist�  ing of the feces and urine of domestic livestock, with or without litter such  as straw, hay, or bedding. Some countries also use human excrement  (�night soil�). Though livestock manure is less rich in nitrogen, phospho�  rus, and potash than synthetic fertilizers and therefore must be applied in  much greater quantities, it is rich in organic matter, or HUMUS, and thus  improves the capacity of the soil to absorb and store water, thereby pre�  venting erosion. Because manure must be carefully stored and spread in  order to derive the most benefit, some farmers decline to expend the nec�  essary time and effort. Manufactured chemical fertilizers, though more  concentrated and efficient, are also more costly and more likely to cause  excess runoff and pollution. See also green manure.</p><p>Manutius \m3- l nu-shos\, Aldus, the Elder Italian Aldo Manuzio  il Vecchio (b. 1449, Bassiano, Papal States�d. Feb. 6, 1515, Venice)  Italian printer, the leading figure of his time in printing, publishing, and  typography. In 1490 he settled in Venice and gathered around him a group  of compositors and Greek scholars. He produced the first printed editions  of many Greek and Latin classics and is particularly associated with the  production of small, carefully edited pocket-size books printed in inex�  pensive editions. The Hypnerotomachia Poliphili (1499) of Francesco  Colonna, with outstanding woodcuts, was his most famous book. After his  death, the Aldine Press, which he founded, was taken over by members of  his family, who probably printed 1,000 editions between 1495 and 1595.</p><p>Manx cat Breed of domestic cat believed to have come from the Isle of  Man.

Sacred Hymns (1815), and  later two historical tragedies influ�  enced by William Shakespeare, II  conte di Carmagnola (1820) and  Adelchi (performed 1822). He is best  known for the novel The Betrothed,</p><p>3 vol. (1827), a masterpiece of world  literature and the most famous Ital�  ian novel of its century, in which,  prompted by a patriotic urge to forge  a language accessible to a wide read�  ership, he employed a clear, expres�  sive prose that became a model for  many subsequent Italian writers.</p><p>Manzoni�s advocacy of a united Italy  made him a hero of the Risorgimento;  his death prompted Giuseppe Verdi�s  great Requiem.</p><p>Manzu Vmand-ztiV Giacomo orig.

Yang  Xi was visited by a group of perfected immortals ( zhenren ) from the heaven  of Shangqing (Supreme Purity), who gave him a new set of scriptures and  instructions on the coming apocalypse, during which the good were to take  refuge in luminous caverns beneath such sacred mountains as Mao Shan.  The Mao Shan revelations incorporated elements of Buddhism into Daoist  thought and proposed reforms of Daoism, including rejection of its sexual  rites in favour of a spiritualized union with a celestial partner.</p><p>Mao Zedong Vmau-dzs-'duqN or Mao Tse-tung (b. Dec. 26, 1893,  Shaoshan, Hunan province, China�d. Sept. 9, 1976, Beijing) Chinese</p><p>Marxist theorist, soldier, and statesman who led China�s communist revo�  lution and served as chairman of the People�s Republic of China (1949�  59) and chairman of the Chinese Communist Party (CCP; 1931-76). The  son of a peasant, Mao joined the revolutionary army that overthrew the  Qing dynasty but, after six months as a soldier, left to acquire more edu�  cation. At Beijing University he met L Dazhao and Chen Duxiu, founders  of the CCP, and in 1921 he committed himself to Marxism. At that time,  Marxist thought held that revolution lay in the hands of urban workers,  but in 1925 Mao concluded that in China it was the peasantry, not the  urban proletariat, that had to be mobilized. He became chairman of a Chi�  nese Soviet Republic formed in rural Jiangxi province; its Red Army  withstood repeated attacks from Chiang Kai-shek�s Nationalist army but at  last undertook the Long March to a more secure position in northwestern  China. There Mao became the undisputed head of the CCP. Guerrilla war�  fare tactics, appeals to the local population�s nationalist sentiments, and  Mao�s agrarian policies gained the party military advantages against their  Nationalist and Japanese enemies and broad support among the peasantry.  Mao�s agrarian Marxism differed from the Soviet model, but, when the  communists succeeded in taking power in China in 1949, the Soviet Union  agreed to provide the new state with technical assistance. However, Mao�s  Great Leap Forward and his criticism of �new bourgeois elements� in the  Soviet Union and China alienated the Soviet Union irrevocably; Soviet  aid was withdrawn in 1960. Mao followed the failed Great Leap Forward  with the Cultural Revolution, also considered to have been a disastrous  mistake. After Mao�s death, Deng Xiaoping introduced social and eco�  nomic reforms that began reversing the policies put in place by Mao. See  also Jiang Qing; Liu Shaoqi; Maoism.</p><p>Maoism Vmau-.i-zomX Variation of Marxism and Leninism developed by  Mao Zedong. It diverged from its antecedents in its agrarian focus: Mao  substituted the dormant power of the peasantry (discounted by traditional  Marxists) for the urban proletariat that China largely lacked. The Maoist  faith in revolutionary enthusiasm and the positive value of the peasants�  lack of sophistication as opposed to technological or intellectual elites  fueled the Great Leap Forward of the 1950s and the Cultural Revolution of  the 1960s and �70s. The disastrous consequences of both upheavals led  Mao�s successors to abandon Maoism as counterproductive to economic  growth and social order. Maoism was embraced by insurgent guerrilla  groups worldwide; under the Khmer Rouge it became Cambodia�s national  ideology.</p><p>Maori Vmau-re\ Any member of a Polynesian people of New Zealand.  Maori traditional history describes their origins in terms of waves of  migration from a mythical land between the 12th and 14th centuries, but  archaeologists have dated habitations in New Zealand back to at least ad  800. Their first European contact was with Abel Janszoon Tasman (1642),  who did battle with a group of Maori. Later Europeans were initially wel�  comed, but the arrival of muskets, disease, Western agricultural methods,  and missionaries corroded Maori culture and social structure, and con�  flicts arose. The British assumed formal control of New Zealand in 1840;  war over land broke out repeatedly over the next three decades. By 1872  all fighting had ended and great tracts of Maori land had been confis�  cated. Today about 9% of New Zealanders are classified as Maori; nearly  all have some European ancestry. Though largely integrated into modern  urban life, many Maori keep alive traditional cultural practices and  struggle to retain control of their ancestral lands.</p><p>map Graphic representation, drawn to scale and usually on a flat sur�  face, of features�usually geographic, geologic, or geopolitical�of an  area of the Earth or of any celestial body.

March 9, 1989, Boston, Mass.) U.S. photographer. He  attended the Pratt Institute (1963-70). By the mid 1970s he was pursu�  ing what were to remain his favourite subjects throughout his career: still  lifes, flowers, portraits of friends and celebrities, and homoerotic explo�  rations of the male body. His compositions were generally stark, with his  combination of cold studio light and precise focus creating dramatic tonal  contrasts. His muscular male models were generally framed against plain  backdrops, sometimes engaged in sexual activity or posed with sadomas�  ochistic props such as leather and chains. His clear, unflinching style  challenged viewers to confront this imagery. Moreover, the combination  of his choice of subject matter with the photographs� formal beauty and  grounding in art-historical traditions created what many saw as a tension  between pornography and art. A posthumous retrospective exhibition of  his work in 1990, funded partly by the National Endowment for the Arts  (NEA), stirred a debate about government subsidies of �obscene� art and  provoked Congress to enact restrictions on future NEA grants.</p><p>mappo Vmap-.poN In Japanese Buddhism, the age in which the Buddha�s  law will degenerate.

A new period,  in which true faith will again flower, will then be ushered in by the bodhi-  sattva Maitreya (Japanese Miroku). Japanese Buddhists calculate that the  age of mappo began in ad 1052.

The victory was overwhelming: 6,400 Persians but only 192 Athenians  died. It is said that a messenger ran about 25 mi (40 km) back to Athens,  where he announced the victory before dying of exhaustion (see mara�  thon). In another version, an Athenian runner was sent to Sparta before  the battle to ask for help, running 150 mi (240 km) in two days; Sparta  refused, so Athens fought with help only from Plataea.</p><p>Maravi confederacy Vma-ro-veX Centralized system of government  established in southern Africa c. 1480. It was created by members of  related ethnolinguistic groups who had migrated from the north into what</p><p>is now central and southern Malawi. Its seat was southwest of Lake  Malawi, and at its peak in the 17th century it ruled an area stretching from  the Zambezi River to the Mozambique coast. Its leaders traded with the  Portuguese and Arabs in ivory, slaves, and iron. By 1720 it split into sev�  eral autonomous factions.</p><p>marble Granular limestone or dolomite that has recrystallized under the  influence of heat, pressure, and aqueous solutions. The main mineral in  marble is calcite. Commercially, �marble� includes all decorative calcium-  rich rocks that can be polished, as well as some serpentines.

Madison (1803) First decision of the Supreme Court of  the United States to declare an act of Congress unconstitutional, thus estab�  lishing the doctrine of judicial review. In 1801 newly elected Pres. Thomas  Jefferson ordered Secretary of State James Madison to withhold from Wil�  liam Marbury the commission of his appointment by former Pres. John  Adams as justice of the peace in the District of Columbia. Marbury then  requested that the Supreme Court compel Madison to deliver his com�  mission. In denying his request, the court held that it lacked jurisdiction  because the section of the Judiciary Act passed by Congress in 1789 that  authorized the Court to issue such a writ was unconstitutional and thus  invalid. Chief Justice John Marshall, writing for the Court, declared that  the Constitution must always take precedence in any conflict between it  and a law passed by Congress.</p><p>Marc, Franz (b.

His early works were aca�  demic, but exposure to Impressionism and Jugendstil lightened his style, and  in 1911, with Vasily Kandinsky and other abstract painters, he became a  founding member of the Blaue Reiter group. He believed that spiritual  essence is best revealed through abstraction and was passionately inter�  ested in the art of �primitive� peoples, children, and the mentally ill.

Development of the  European march may have been stimulated by the Ottoman invasions of  the 14th-16th centuries. Marches were not notated until the late 16th cen�  tury; until then, time was generally kept by percussion alone, often with  improvised fife embellishment. With the extensive development of brass  instruments, especially in the 19th century, marches became widely popu�  lar and were often elaborately orchestrated. Composers such as Wolfgang  Amadeus Mozart, Ludwig van Beethoven, and Gustav Mahler wrote marches,  often incorporating them into their operas, sonatas, or symphonies. The  later popularity of John Philip Sousa�s band marches was unmatched.</p><p>March, Frederic orig. Frederick Ernest McIntyre Bickel (b.</p><p>Aug. 31, 1897, Racine, Wis., U.S.�d.

He began acting on Broadway, and his parody of John Bar�  rymore in a touring production of The Royal Family earned him a five-  year contract with Paramount Pictures; he reprised the role in the retitled  screen adaptation, The Royal Family of Broadway (1930). He subse�  quently appeared in more than 65 films, including Dr. Jekyll and Mr. Hyde  (1932, Academy Award), A Star Is Born (1937), The Best Years of Our  Lives (1946, Academy Award), Death of a Salesman (1951), and Inherit  the Wind (1960). He starred on the stage, often with his wife, Florence  Eldridge, in plays such as The Skin of Our Teeth (1942) and Long Day�s  Journey into Night (1956, Tony Award). A versatile stage and film actor,  his cerebral approach occasionally resulted in stolid, emotionally uncon�  vincing performances, but it more often produced compelling, complex  characterizations.</p><p>March Laws Reform measures enacted by the Hungarian Diet in 1848  (see Revolutions of 1848) that sought to create a modem national Mag�  yar state. The program, presented to the Diet by Kossuth Lajos, provided  for internal Hungarian control of its own national guard, budget, and for�  eign policy. The laws were constitutionally confirmed by Emperor Ferdi�  nand I in April 1848. Austria denied the validity of the laws after the  revolution was defeated (1849), but Hungary continued to insist on their  legality.

Originally inhabited by Gauls and Picenes, it came  under Roman rule by ad 292. During the early Middle Ages the southern  part was ruled by the Lombards and the northern part by the Byzantines.  Conflicts arose in 12th and 13th centuries with powerful feudal families  and the attempt of the popes to reestablish their temporal authority; this  culminated in 1631, when the duchy of Urbino was incorporated into the  Papal States.

In his first term he made progress  in agriculture, industry, and education, but in 1972 he imposed martial  law, and his later years in power were noted for rampant government cor�  ruption, economic stagnation, political repression, and the steady growth  of a communist insurgency. Following public outcry over the assassina�  tion of the opposition leader Benigno Aquino (1932-83) and Marcos�s  apparently fraudulent electoral victory over Aquino�s widow, Corazon  Aquino, Marcos was forced into exile in Hawaii, U.S. There he and his  wife, Imelda, were indicted on racketeering charges related to embezzling  billions of dollars from the Philippine economy.

His reign was  marked by numerous military crises,  all the major frontiers being threat�  ened by invasion.

After working in U.S. intelligence in World War II, he taught at  several universities, principally Brandeis University (1954-65) and the  University of California at San Diego (1965-76). In his best known and  most influential work, One-Dimensional Man (1964), Marcuse argued that  society under advanced capitalism is unfree and repressive and that mod�  ern man has become intellectually and spiritually complacent through his  psychological dependence on the blandishments of consumer society, a  phenomenon he termed �repressive desublimation.� He was also hostile  to the Soviet system.

This excess pro�  vides the lender a �margin� of safety over and above the collateral offered  and thus makes extending a loan a more attractive proposition. The size  of the margin varies with the type of collateral, the stability of its market  price, and the credit standing of the borrower. The term margin is also  used in reference to securities transactions. When securities are purchased  �on margin,� the buyer supplies a percentage of the purchase price in cash,  pledges the security as collateral, and borrows the remainder from the  broker. The U.S. Federal Reserve Board (see Federal Reserve System) sets  minimum margin requirements on loans made for the purpose of buying  securities, so as to prevent excessive use of credit for speculation in stocks,  as happened before the stock-market crash of 1929.</p><p>marginal-cost pricing In economics, the practice of setting a prod�  uct�s price equal to the additional (marginal) cost of producing one more  unit of output. The producer charges an amount equal to the cost of the  additional economic resources. The policy is used to maintain a low sell�  ing price or to keep a business operating during a period of poor sales.  Because fixed costs such as rent and building maintenance must be paid  whether a company produces or not, a firm experiencing temporary dif�  ficulties may decide to remain in production and sell the product at mar�  ginal cost, since its losses will be no greater than if it ceased production.</p><p>marginal productivity theory In economics, the theory that firms  will pay a productive agent only what he or she adds to the financial earn�  ings of the firm. Developed by writers such as John Bates Clark and Philip  Henry Wicksteed at the end of the 19th century, marginal productivity  theory holds that it is unprofitable to buy, for example, a man-hour of  labour if it costs more than it contributes to its buyer�s income. The  amount in excess of costs that a productive input yields is the value of  its marginal product; the theory posits that every type of input should be  paid the value of its marginal product.</p><p>marginal utility In economics, the additional satisfaction or benefit  (utility) that a consumer derives from buying an additional unit of a com�  modity or service. The law of diminishing utility implies that utility or  benefit is inversely related to the number of units already owned. For  example, the marginal utility of one slice of bread offered to a family that  has five slices will be great, since the family will be less hungry and the  difference between five and six is proportionally significant. An extra slice  offered to a family that has 30 slices will have less marginal utility, since  the difference between 30 and 31 is proportionally smaller and the fami�  ly�s appetite may be satisfied by what it already has. The concept grew  out of attempts by 19th-century economists to explain the fundamental  economic reality of price.</p><p>marguerite V.mar-go-'reA Any of several genera of golden daisylike  flowers in the composite family. Yellow or white ray flowers and yellow  disk flowers are borne in the compact flower heads.

It originated in Kenya in 1963 when two Catholics of the Luo  group, Simeon Ondeto and Gaundencia Aoko, claimed to have undergone  prophetic experiences. The church, which offers healing by prayer and  exorcism of evil spirits, adds features of Pentecostalism to Catholic wor�  ship and hierarchy. In its first year it gained about 90,000 adherents, but  membership had dropped to 50,000 by the end of the decade. It rejects  Western and traditional medicines, alcohol, tobacco, and dancing but  accepts polygamy and is strongly nationalistic.</p><p>Maria Theresa \to-'ra-s9\ German Maria Theresia (b.

She was the eldest  daughter of Emperor Charles VI, who promulgated the Pragmatic Sanction  to allow her to succeed to the Habsburg domains. Opposition to her suc�  cession led in 1740 to the War of the Austrian Succession. After Emperor  Charles VII died (1745), she obtained the imperial crown for her husband,  who became Francis I.

She criticized many of his actions but agreed  to the partition of Poland (1772). A key figure in the power politics of  18th-century Europe, Maria Theresa brought unity to the Habsburg mon�  archy and was considered one of its most capable rulers. Her 16 children  also included Marie-Antoinette and Leopold II.</p><p>mariachi \,mar-e-'a-che\ Traditional Mexican street ensemble. In the  19th century, mariachis consisted solely of stringed instruments, includ�  ing violin, guitar, guitarron, vihuela, mandolin, and double bass; since the  1920s they have generally included trumpets and often other wind instru�  ments as well.

In  1919 he was sent to study in Italy, where he met leading socialists of the  day, including Maxim Gorky. At first a strong supporter of APRA, he split  with that movement to form the Peruvian Communist Party in 1928.  While emphasizing the economic aspects of Marxism in his writings, he  recognized the value of religion and myth in his treatment of the Indians  and advocated a greater social and political role for them. His influence  is seen in the Maoist Shining Path revolutionary movement.</p><p>Ma�rib Vmar-ib\ Ancient city ruins, north-central Yemen.

After he became  king (1774), she was criticized for  her extravagance and frivolous circle  of court favourites. She was unjustly  implicated in the Affair of the Dia�  mond Necklace (1786), which dis�  credited the monarchy. After the  French Revolution began, she influ�  enced Louis to resist attempts by the  National Assembly to restrict the  royal prerogative. She became the</p><p>Marie-Antoinette, detail of a portrait  by Elisabeth Vigee-Lebrun; in the Cha�  teau de Versailles.</p><p>CUCHE MUSEES NATIONAUX</p><p>target of agitators, who attributed to her the celebrated remark, after being  told the people had no bread, �Let them eat cake!� She tried to save the  crown by negotiating secretly with monarchist factions and with her  brother, Emperor Leopold II. News of her intrigues further enraged the  French and led to the overthrow of the monarchy (1792). After a year in  prison, she was tried and guillotined in 1793.</p><p>Marie de France (fl. 12th century) French poet, the earliest known  woman poet of France. She wrote verse narratives on romantic and magi�  cal themes and may have inspired the musical lais of the later trouba�  dours. She probably wrote in England and may have based her fables on  an English source; her verses were dedicated to a �noble� king, either  Henry II of England or his son. She also wrote a collection of fables, the  Ysopet.</p><p>Marie de Medicis Xdo-ma-de-'sesX Italian Maria de' Medici (b.</p><p>April 26, 1573, Florence�d. July 3, 1642, Cologne) Queen consort of  Henry IV of France. The daughter of Francesco de� Medici, of the noted  Medici family, she was married in 1600 to Henry as his second wife. On  his assassination in 1610, she became regent for their son, Louis XIII.  Guided by the unscrupulous marquess d�Ancre, she squandered state rev�  enues and bought the loyalty of rebellious nobles. After Ancre was assas�  sinated, Louis assumed the throne (1617) and exiled Marie to Blois. She  tried to raise a revolt and won favourable peace terms through her adviser,  the future cardinal de Richelieu. Restored to the king�s council (1622), she  obtained a cardinal�s hat for Richelieu and persuaded Louis to make him  chief minister. Richelieu gradually withdrew from Marie�s influence and  by 1628 was opposing her policies. She attempted to have him dismissed,  but Louis rejected her plot and banished Marie from court. In 1631 she  fled to Brussels, where she later died in poverty.</p><p>Marie-Louise German Maria-  Luise (b. Dec. 12, 1791, Vienna,</p><p>Austria�d.

Ballet was not  performed there until 1880 and was presented regularly only after 1889,  when the Imperial Russian Ballet became its resident company and  acquired the Mariinsky name. The theatre�s name was changed to the State  Academic Theatre (1917-35) and later to the Kirov (for Sergey Kirov)  State Academic Theatre for Opera and Ballet (1935-91); it reverted to its  original name in 1991. Its resident ballet company, the celebrated Mari�  insky (or Kirov) Ballet, tours worldwide.</p><p>marijuana V.mar-o-'wa-noX Indian hemp plant (Cannabis sativa ) or the  crude drug made of its dried and crushed leaves or flowers. The active  ingredient is tetrahydrocannabinol (THC). Also called pot, grass, and  weed, the drug has long been used as a sedative or analgesic; it was in  use in China by the 3rd millennium bc and had reached Europe by ad  500. Today it is used worldwide, though it has been generally illegal at  least since the International Opium Convention of 1925. Its psychologi�  cal and physical effects, including mild euphoria and alterations in vision  and judgment, vary with strength and amount consumed, the setting, and  the user�s experience. Chronic use is not physically habit-forming but may  be mildly psychologically habit-forming. Marijuana has been shown to  be medically therapeutic for patients with glaucoma, AIDS, and the side  effects of chemotherapy; in 2001 Canada became the first country to legal�  ize the use of marijuana by people with terminal illnesses and chronic  conditions. Supporters of legalization claim that it is a more benign drug  than alcohol; opponents contend that it is addictive and leads to use of  more serious drugs. A resin from the plant is the source of hashish.</p><p>marimba Xylophone with resonators under each bar. The original Afri�  can instrument uses tuned calabash resonators.

He worked  as an architectural draftsman before studying painting. After exposure to  Cubism and German Expressionism, he developed a personal form of expres�  sionism, consisting of semiabstract images based on objective reality.  While watercolour usually produces delicate, transparent effects, Marin�s  command of the medium allowed him to use it to render the monumental  power of New York City and the relentless surge of the sea.</p><p>"Maine Islands," watercolour by John Marin, 1922; in the Phillips Collection,  Washington, D.C.</p><p>COURTESY OF THE PHILLIPS COLLECTION, WASHINGTON, D.C.</p><p>Marin, Luis Munoz See Luis Munoz Marin</p><p>Marina See Espirito Santo</p><p>Marina, Saint See Saint Margaret of Antioch</p><p>marine Member of a military force trained for service at sea and in land  operations related to naval campaigns.

In the Middle Ages ordinary soldiers were often  assigned to shipboard duty; not until the naval wars of the 17th century  was the distinct role of marines rediscovered almost simultaneously by  the British and the Dutch, who raised the first two modern marine corps,  the Royal Marine (1664) and the Koninklijke Nederlandse Corps  Mariniers (1665). See also U.S. Marine Corps.</p><p>marine biology Science that deals with the animals and plants of the  sea and estuaries and with airborne and terrestrial organisms that depend  directly on bodies of saltwater for food and other necessities. Marine  biologists study the relations between ocean phenomena and the distri�  bution and adaptations of organisms. Of particular interest are adaptations  to the chemical and physical properties of seawater, the movements and  currents of the ocean, the availability of light at various depths, and the  composition of the sea floor. Other important areas of study are marine  food chains, the distribution of economically important fish and crusta�  ceans, and the effects of pollution. In the later 19th century, the emphasis  was on collecting and cataloging marine organisms, for which special  nets, dredges, and trawls were developed. In the 20th century, improved  diving equipment, submersible craft, and underwater cameras and televi�  sion have made direct observation possible.</p><p>marine geology or geologic oceanography Scientific disci�  pline concerned with all geologic aspects of the continental shelves and  slopes and the ocean basins. Marine geology originally focused on marine  sedimentation and the interpretation of bottom samples. The advent of the  concept of seafloor spreading, however, broadened its scope. Many inves�  tigations of the oceanic ridge system, the magnetism of rocks on the sea�  floor, geochemical analyses of deep brine pools, and seafloor spreading  and continental drift may be considered within the general realm of marine  geology.</p><p>marine geophysics Subdiscipline of geophysics that is concerned with  ocean phenomena. The main techniques and areas of study include heat-  flow data, seismic reflection and refraction techniques, geomagnetics, and  gravity studies. The principal concepts in marine geophysics are seafloor  SPREADING, CONTINENTAL DRIFT, and PLATE tectonics.</p><p>marine sediment Any deposit of insoluble material, primarily rock  and soil particles, transported from land areas to the ocean by wind, ice,  and rivers, as well as the remains of marine organisms, products of sub�  marine volcanic activity, and chemical precipitates from seawater that  accumulate on the seafloor.</p><p>Mariner Vmar-o-norf Any of a series of unmanned U.S. space probes  sent near Venus, Mars, and Mercury.

Mariners 4 (1965), 6 and 7 (1969), and 9 (1971-72) obtained  striking photographs of the surface of Mars and analyzed its atmosphere  and magnetic field. Mariner 10 is the only spacecraft ever to have visited  Mercury (1974-75).</p><p>Marinetti X.ma-re-'nat-teV Filippo Tommaso (Emilio) (b. Dec. 22,  1876, Alexandria, Egypt�d. Dec. 2, 1944, Bellagio, Italy) Italian-French  writer, the ideological founder of Futurism. In early poetry such as Destruc�  tion (1904), he showed the vigour and anarchic experimentation with form  that would characterize his later work. Futurism officially began with the  1909 publication of his manifesto in the Paris newspaper Le Figaro. His  ideas were quickly adopted in Italy, and he later elaborated on his theory  in a novel and several dramatic works. Arguing that fascism was Futur�  ism�s natural extension, he became an active fascist and lost most of his  following in the 1920s.</p><p>Marini, Marino (b. Feb. 27, 1901, Pistoia, Italy�d. Aug. 6, 1980,  Viareggio) Italian sculptor and painter. Working primarily in bronze, he  concentrated on two major images: the earthbound woman and the horse  and rider. His sensitivity to form and surface owes much to Etruscan and  Roman works, but the inner tension of his bold, straining figures reflects  an Expressionist sensibility. His portrait busts, as of Igor Stravinsky  (1950), capture the spiritual substratum of his subjects. In the 1940s he  turned to painting nearly abstract works.</p><p>Marinid Vmar-i- l nid\ dynasty Berber dynasty that followed the Almo-  had dynasty in North Africa in the 13th�15th centuries.

In 1984  he became the first quarterback to pass for more than 5,000 yards in a  single season (5,084) and the first to complete over 40 touchdown passes  (48) in a season.</p><p>Marino, Giambattista (b. Oct. 18, 1569, Naples�d. March 25,  1625, Naples) Italian poet, founder of the school of Marinism (later secen-  tismo), which dominated 17th-century Italian poetry. Trained as a lawyer,  Marino chose not to practice and instead found immense success with  poetry that he managed to get published despite censorship. His most  important work, a labour of 20 years, is Adonis (1623), an enormous poem  (45,000 lines) that relates, with many digressions, the love story of Venus  and Adonis. His work, praised throughout Europe, far surpassed that of  his imitators, who carried his complicated wordplay and elaborate con�  ceits and metaphors to such extremes that Marinism became a pejorative  term.</p><p>Mariology \,mar-e-'a-l3-je\ Study of doctrines concerning Mary, the  mother of Jesus, or the content of those doctrines. The New Testament  contains little information about Mary, though the tradition that she  remained a virgin despite giving birth to Jesus was accepted in the early  church. Various feast days in her honour were established in both the  Eastern and Western liturgical traditions, and she became an especially  important figure in Roman Catholicism. Pius IX proclaimed the doctrine of  the Immaculate Conception in 1854. Mary is seen as the spiritual mother  and heavenly intercessor of every Catholic and as a partner with Jesus in  the redemption of human beings. In 1950 Pius XII proclaimed the doctrine  that at her death Mary was bodily assumed into heaven.</p><p>Marion, Francis known as The Swamp Fox (b. c. 1732, Winyah,  S.C.�d.

In the American Revolution he  commanded troops in South Carolina. After the surrender of Gen. Ben�  jamin Lincoln to the British at Charleston, S.C. (1780), he slipped away to  the swamps, gathered together his band of guerrillas, and began leading  bold raids on British positions. For a daring rescue of American troops  surrounded by the British at Parkers Ferry, S.C. (1781), he received the  thanks of Congress. He was then appointed a brigadier general.</p><p>marionette Puppet figure manipulated from above by strings attached  to a wooden cross or control. The figure, also called a string puppet, is  usually manipulated by nine strings, attached to each leg, hand, shoulder,  and ear and at the base of the spine. Additional strings give more sensi�  tive control of movement, and some marionettes can be made to imitate  almost every human and animal action. Early marionettes were controlled  by an iron rod instead of strings, a form that survived in Sicily. In the 18th  century, marionette operas were extremely popular, and they are still per�  formed today in Salzburg to Mozart�s music.

Maris�s family moved from Minnesota to North Dakota  when he was 10, and there he excelled in high school sports, playing  American Legion baseball in Fargo in the summer. An outfielder and left-  handed hitter, he played for the Cleveland Indians, the New York Yan�  kees, and the St. Louis Cardinals. In 1961 his one-season total of 61 home  runs broke Babe Ruth�s long-standing record of 60, edging out his Yankee  teammate Mickey Mantle.

His thought, which is based on  Aristotelianism and Thomism, incorporates ideas of other Classical and  modern philosophers and draws upon anthropology, sociology, and psy�</p><p>chology. Among the dominant themes in his work are: that science, phi�  losophy, poetry, and mysticism are among many legitimate ways of  knowing reality; that the individual person transcends the political com�  munity; that natural law expresses not only what is natural in the world  but also what is known naturally by human beings; that moral philoso�  phy must take into account other branches of human knowledge; and that  people holding different beliefs must cooperate in the formation and main�  tenance of salutary political institutions. Among his major works are Art  and Scholasticism (1920), The Degrees of Knowledge (1932), Art and  Poetry (1935), Man and the State (1951), and Moral Philosophy (1960).</p><p>maritime law or admiralty law or admiralty Body of legal  rules that governs ships and shipping. One early compilation of maritime  regulations is the 6th-century Digest of Justinian. Roman maritime law  and the 13th-century Consolat de Mar (�Consulate of the Sea�) both  brought temporary uniformity of maritime law to the Mediterranean, but  nationalism led many countries to develop their own maritime codes.  Maritime law deals mainly with the eventualities of loss of a ship (e.g.,  through collision) or cargo, with insurance and liability relating to those  eventualities, and with collision compensation and salvage rights. There  has been an increasing tendency to make maritime laws uniform; the chief  organization overseeing maritime law is the International Maritime Com�  mittee, composed of the maritime law associations of several countries.</p><p>Maritime Provinces Canadian provinces of New Brunswick, Nova  Scotia, and Prince Edward Island.

At Rome he held unconstitutional suc�  cessive consulships (104-100) while it was threatened by the Cimbri and  the Teutones, whom he fought and defeated. He held a command during  the Social War and was awarded another in 88 to replace Sulla as Asian  commander and confront Mithradates.

The loss of his fortune in 1720 and  the death of his young wife a few years later prompted him to embark on  a serious literary career. He wrote his first plays, including the tragedy  Annibal (1720), for the Comedie-Francaise, but he preferred to write for  the Italian commedia dell'arte theatre in Paris, for which he produced Har�  lequin Brightened by Love (1723) and The Game of Love and Chance  (1730). His nuanced feeling and clever wordplay became known as  marivaudage.

The commodity exchanges in London and New York,  for example, are international markets in which dealers communicate by  telephone and computer links as well as through direct contact. Markets  trade not only in tangible commodities such as grain and livestock but  also in financial instruments such as securities and currencies. Classical  economists developed the theory of perfect competition, in which they  imagined free markets as places where large numbers of buyers and sell�  ers communicated easily with each other and traded in commodities that  were readily transferable; prices in such markets were determined only  by supply and demand. Since the 1930s, economists have focused more  often on the theory of imperfect competition, in which supply and demand  are not the only factors that influence the operations of the market. In  imperfect competition the number of sellers or buyers is limited, rival  products are differentiated (by design, quality, brand name, etc.), and  various obstacles hinder new producers� entry into the market.</p><p>market research Study of the requirements of specific markets, the  acceptability of products, and methods of developing and exploiting new  markets. Various strategies are used for market research: past sales may  be projected forward; surveys may be made of consumer attitudes and  product preferences; and new or altered products may be introduced  experimentally into designated test-market areas. Formal market research  dates back to the 1920s in Germany and the 1930s in Sweden and France.  After World War II, U.S. firms led in the use and refinement of market-  research techniques, which spread throughout much of Western Europe  and Japan.</p><p>marketing Activities that direct the flow of goods and services from  producers to consumers. In advanced industrial economies, marketing  considerations play a major role in determining corporate policy. Once  primarily concerned with increasing sales through advertising and other  promotional techniques, corporate marketing departments now focus on  credit policies (see credit), product development, customer support, dis�  tribution, and corporate communications. Marketers may look for outlets  through which to sell the company�s products, including retail stores,  direct-mail marketing, and wholesaling. They may make psychological and  demographic studies of a potential market, experiment with various mar�  keting strategies, and conduct informal interviews with target audiences.  Marketing is used both to increase sales of an existing product and to  introduce new products. See also merchandising.</p><p>marketing board Organization set up by a government to regulate  the buying and selling of a certain commodity within a specified area.  The simplest type of board is designed to carry out market research, pro�  mote sales, and furnish information; it is usually financed by a fee levied  on all sales of the product concerned. Examples include the Sri Lanka Tea  Board and the Ghana Cocoa Board. Other boards are empowered to regu�  late terms and conditions of sale, usually by establishing packing stan�  dards and quality analysis. The primary goal of most marketing boards is  to stabilize prices, especially of products intended for the export market,  where price fluctuations are often extreme. The boards may raise average  prices through manipulation of commodity flows, with the objective of  maintaining reasonably high levels of demand at all times. Marketing  boards such as the Washington State Apple Commission are used for  products whose perishability requires that outlets be set up in advance.

May 26, 1650,</p><p>Ashe, Devon, Eng.�d. June 16, _</p><p>1722, Windsor, near London) British  military commander. He served with  distinction at Maastricht (1673), was  promoted rapidly, and advanced at  court, in part because his wife (see  Sarah Jennings, duchess of Marlbor�  ough) was a confidant of Princess  (later Queen) Anne. On the accession  of James II in 1685, Churchill was  made a lieutenant general and effec�  tive commander in chief. In 1688 he  transferred his allegiance to William  III, who rewarded him with the earl�  dom of Marlborough and a succes�  sion of commands in Flanders and  Ireland. His relationship with Will�  iam deteriorated in the 1690s. Queen  Anne appointed him commander of  English and Dutch forces in the War  of the Spanish Succession, and for his  successes he was created duke of  Marlborough (1702). His victory at  the Battle of Blenheim (1704) helped change the balance of power in  Europe. In gratitude, he was granted a royal manor, where Blenheim Pal�  ace was built. His outstanding military tactics continued to produce vic�  tories, notably at Ramillies (1706) and Oudenaarde (1708). His influence  with Queen Anne and financial backing for the war were undermined by  intrigue between Tories and Whigs. After his Whig allies lost the election  of 1710, he was dismissed on charges of misuse of public money.

Born in the hill country of Jamaica to a white father  and a black mother, Marley was living in the Kingston slum known as  Trench Town in the early 1960s when he formed the Wailers with Peter  Tosh and Bunny Livingston (Bunny Wailer). Mixing the Jamaican musi�  cal forms of ska and rock steady with rock, they helped to pioneer reg�  gae and became its first international stars with releases such as Catch a  Fire (1973), Exodus (1977), and Uprising (1980).

May 30, 1593, Deptford, near London) British poet and play�  wright. The son of a Canterbury shoemaker, he earned a degree from  Cambridge University. From 1587 he wrote plays for London theatres,  starting with Tamburlaine the Great (published 1590), in which he estab�  lished dramatic blank verse. Tamburlaine was followed by Dido, Queen of  Carthage (published 1594), cowritten with Thomas Nashe; The Massacre  at Paris (c. 1594); and Edward II (1594). His most famous play is The  Tragicall History of Doctor Faustus (published 1604), which uses the  dramatic framework of a morality play in its presentation of a story of  temptation, fall, and damnation. The Jew of Malta (published 1633) may  have been his final work. His poetry includes the unfinished long poem  Hero and Leander. Known for leading a disreputable life, he died a vio�  lent death at age 29 in a tavern brawl; he may have been assassinated  because of his service as a government spy. His brilliant, though short,  career makes him William Shakespeare�s most important contemporary in  English drama.</p><p>Marmara Vmar-ma-roV Sea of Inland sea lying between the Asian  and European parts of Turkey. It is connected with the Black Sea through  the Bosporus, and with the Aegean Sea through the Dardanelles. It is 175  mi (280 km) long and nearly 50 mi (80 km) wide, and it occupies an area  of 4,382 sq mi (11,350 sq km). The sea has two distinct island groups.  The Kizil Islands in the northeast are primarily resort areas. The Marmara  Islands in the southwest are rich in granite, slate, and marble, which have  been quarried since antiquity.</p><p>marmoset Any species of arboreal, diurnal, long-tailed South Ameri�  can monkey (family Callitrichidae) classified in two groups: eight species  with short tusks (lower canine teeth), called marmosets, and 25 with long  tusks, called tamarins. Marmosets move in a quick, jerky manner and eat  insects and sometimes fruit and small animals. Members of the common  marmoset genus Callithrix are 6-10 in. (15-25 cm) long, excluding the  10-16-in.

After the invading German  forces had moved to within 30 mi (50 km) of Paris at the Marne River,  Joseph-Jacques-Cesaire Joffre counterattacked and halted the German  advance. French reinforcements were driven to the front by 600 Paris  taxis, the first automotive transport of troops. French and British troops  forced the Germans to retreat north of the Aisne River, where they dug  in to conduct the trench warfare of the next three years.

As part of its final offensive to split the French  forces, German troops under Erich Ludendorff crossed the Marne River  but were met by strong French resistance under Ferdinand Foch. Allied  counterattacks, especially at the Marne salient, forced the Germans to  retreat to their former position along the Aisne and Vesle rivers.</p><p>Marne \'marn\ River River, northeastern France. It flows northwest into  the Seine River near Paris. It is navigable for 220 mi (350 km) of its total  length of 326 mi (525 km) and has extensive canals.

Its  upper course is known as the Litani in Suriname or Itany in French Gui�  ana; its middle course is called the Lawa or Aoua. Shallow-draft vessels  can navigate about 60 mi (100 km) upstream from the river�s mouth.</p><p>Maronite Church Vmar-o-.nltX Eastern-rite community centered in  Lebanon (see Eastern Rite Church). It traces its origin to St. Maron, a Syr�  ian hermit of the 4th-5th century ad, and St. John Maron, under whom  the invading Byzantine forces were defeated in 684. For several centu�  ries the Maronites were considered heretics, followers of Sergius, patri�  arch of Constantinople, who taught that Jesus had only a divine will and  not a human will. No permanent affiliation with Rome took place until  the 16th century. A hardy mountain people, the Maronites preserved their  freedom in Lebanon during the Muslim caliphate. In 1860 the Ottoman  government incited a massacre of the Maronites by the Druze, an event  that led to the establishment of Maronite autonomy within the Ottoman  empire. The Maronites obtained self-rule under French protection in the  early 20th century. Since the establishment of a fully independent Leba�  non in 1943, they have constituted a major religious group in the coun�  try. Their spiritual leader (after the pope) is the patriarch of Antioch, and  the church retains the ancient West Syrian liturgy.</p><p>Marot \ma-'ro\, Clement (b. 1496?, Cahors, France�d. September  1544, Turin, Savoy) French poet. While imprisoned in 1526 for defying  Lenten abstinence regulations, he wrote some of his best-known works,  including �The Inferno,� an allegorical satire on justice. He held several  court posts; his long service to Francis I was only briefly interrupted. One  of the greatest poets of the French Renaissance, he markedly influenced  the style of his successors with his use of the forms and imagery of Latin  poetry. When not writing official court poems, he spent most of his time  translating the Psalms.</p><p>Marquesas \mar-'ka-s3z\ Islands Island group (pop., 1996: 8,064),  French Polynesia.

In  1673 he accompanied Louis Jolliet on his exploration of the Mississippi  River, traveling south to the mouth of the Arkansas River. They returned  via the Illinois River to Green Bay on Lake Michigan, where Marquette  remained. In 1674 he set out to found a mission among the Illinois Indi�  ans, reaching the site of present-day Chicago.

It fell  to the Almohad dynasty in 1147, passed to the Marinid dynasty in 1269, and  was the capital under the Sa'did dynasty in the 16th century. In the pre�  modern era, it was one of Islam�s great cities. In 1912 it was captured by  the French, who dominated the city until 1956. Now a popular tourist  destination, it has many historical buildings and a well-known souk within  its ancient city centre (designated a UNESCO World Heritage site in 1985).</p><p>Marrano \ma-'ra-no\ Spanish Jew who converted to Christianity to  escape persecution but continued to practice Judaism secretly. During  fierce persecutions in the late 14th century, many Jews died rather than  renounce their faith, but at least 100,000 converted to Christianity in order  to survive. In time the Marranos came to form a compact society within  Spain, growing rich and gaining political power. They were viewed with  suspicion, and the name Marrano was originally a term of abuse. Resent�  ment against them led to riots and massacres in 1473. In 1480 the Inqui�  sition intensified the persecution, and thousands of Marranos lost their  lives. In 1492 a royal edict ordered the expulsion of all Jews who refused  to renounce their faith. Many Marranos settled in North Africa and West�  ern Europe. By the 18th century, emigration and assimilation had led to  the disappearance of the Marranos in Spain.</p><p>marriage Legally and socially sanctioned union, usually between a  man and a woman, that is regulated by laws, rules, customs, beliefs, and  attitudes that prescribe the rights and duties of the partners and accords  status to their offspring (if any). The universality of marriage is attributed  to the many basic social and personal functions it performs, such as pro�  creation, regulation of sexual behaviour, care of children and their edu�  cation and socialization, regulation of lines of descent, division of labour  between the sexes, economic production and consumption, and satisfac�  tion of personal needs for social status, affection, and companionship.  Until modern times marriage was rarely a matter of free choice, and it</p><p>was rarely motivated by romantic love. In most eras and most societies,  permissible marriage partners have been carefully regulated. In societies  in which the extended family remains the basic unit, marriages are usually  arranged by the family. The assumption is that love between the partners  comes after marriage, and much thought is given to the socioeconomic  advantages accruing to the larger family from the match. Some form of  dowry or bridewealth is almost universal in societies that use arranged  marriages. The rituals and ceremonies surrounding marriage are associ�  ated primarily with religion and fertility and validate the importance of  marriage for the continuation of a family, clan, tribe, or society. In recent  years the definition of marriage as a union between members of opposite  sexes has been challenged, and in 2000 The Netherlands became the first  country to legalize same-sex marriages. See also bridewealth; divorce;  dowry; exogamy and endogamy; polygamy.</p><p>marriage chest See cassone</p><p>marriage law Body of legal specifications and requirements and other  laws that regulate the initiation, continuation, and validity of marriages.  In western Europe most marriage law derives from Roman Catholic canon  law. Although the church regards marriage as a sacred, indissoluble union,  modern western European and U.S. marriage law treats it as a civil trans�  action. Marriage law allows only monogamous unions; partners must be  above a certain age and not within prohibited degrees of blood relation�  ship; and they must be free to marry and give consent to the marriage.  Divorce is now almost universally allowed. Although Islamic law regards  marriage as a contract between the two spouses for the �legalization of  intercourse and the procreation of children,� it is also considered a gift  from God or a kind of service to God; the Islamic practice of polygamy  was always limited and has waned. Polygamous marriages are permitted  under customary laws in many African countries, though there has been  a growing trend toward monogamy. Marriage law in present-day China  and Japan resembles that in the West. Although most jurisdictions restrict  marriage to a union between a man and a woman, same-sex marriages  have been legalized in The Netherlands, Belgium, Spain, and Canada.  Civil unions or domestic partnerships between persons of the same sex,  which entail many of the rights and obligations assumed by married  couples, are recognized in numerous other jurisdictions, including several  European countries and some U.S. states. Other U.S. jurisdictions, while  not recognizing civil unions or domestic partnerships, grant a range of  legal rights to same-sex couples.</p><p>Marriott Vmar-e-.atX, J(ohn) Willard (b.

He then began a series of adventure novels�including The King�s  Own (1830), Peter Simple (1834), and Poor Jack (1840)�marked by a  lucid, direct narrative style, humour, and incidents drawn from his varied  experience at sea. His Children of the New Forest (1847), set during the  English Civil Wars, is a classic of children�s literature.</p><p>Mars Ancient Roman god of war and protector of Rome, second only  to Jupiter in importance. His festivals occurred in the spring (March) and  fall (October). Until the time of Augustus, Mars had only two temples in  Rome. His sacred spears were kept in a sanctuary; on the outbreak of war,  the consul had to shake the spears, saying �Mars vigila!� (�Mars, awake!�)  Under Augustus, Mars became not only the guardian of Rome in its mili�  tary affairs but the emperor�s personal guardian. He was identified with  the Greek god Ares.</p><p>Mars Fourth planet from the Sun, named after the Roman god of war.  Its mean distance from the Sun is 141 million mi (227 million km). Its  day is 24.6 Earth hours and its year about 687 Earth days. It has two small  moons, Phobos and Deimos. Mars�s equatorial diameter is 4,220 mi  (6,792 km), about half that of Earth, and it is less dense than Earth. Its</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Mars &#x25BA; Marshall I 1201</p><p>mass is about one-tenth of Earth�s and its surface gravity about one-third  as strong. No magnetic field has been detected on Mars, suggesting, as  does its low density, the absence of a substantial metallic core. Like Earth,  it has seasons and an atmosphere, but its average daytime surface tem�  perature is only -10 �F (-20 �C). Mars�s thin atmosphere is mainly car�  bon dioxide, with some nitrogen and argon and traces of water vapour.  Spacecraft images show a cratered surface, with volcanoes, lava plains,  flood channels, and canyons, many large by Earth standards; Olympus  Mons, for example, is the largest known volcano in the solar system. Wind  is an important element on Mars, sculpting features such as dunes and  occasionally causing global dust storms. In the distant past Mars appears  to have had a denser, warmer atmosphere and much more water than at  present. Images from the Mars Global Surveyor spacecraft suggest that  some liquid water may have flowed near the planet�s surface in relatively  recent times. No life has been detected on the planet.</p><p>Mars, canals of Apparent systems of straight-line markings on the  surface of Mars, now known to be an illusion caused by the chance align�  ment of large craters and other surface features. Giovanni Virginio Schi�  aparelli (1835-1910) observed about 100 of what he described as  channels. Percival Lowell called them canals and believed them to be evi�  dence of intelligent life. Most astronomers could not see them, and many  doubted their reality. The controversy was finally resolved only when pic�  tures from Mariner spacecraft showed nothing resembling a network of  channels.</p><p>Mars Pathfinder First spacecraft to land on Mars since the Viking 1976  missions. Launched in 1996 by NASA, Pathfinder descended to the Mar�  tian surface in July 1997 using parachutes, rockets, and air bags.

Marsalis was a trumpet prodigy and  was recognized as an important soloist in both the classical and jazz tra�  ditions at an early age. He joined Art Blakey�s Jazz Messengers (1980-  82) before leading his own groups. As a composer he has written ballet  and concert works, and he won the 1997 Pulitzer Prize for his oratorio  Blood on the Fields. He also worked on Ken Burns�s Jazz miniseries and  was a catalyst in the revival of broad interest in jazz.</p><p>Marseille or Marseilles \mar-'sa\ City (pop., 1999: city, 797,486;  metro, area, 1,349,772), southeastern France. One of the Mediterranean�s  major seaports and the second largest city in France, it is located on the  Gulf of Lion, west of the French Riviera. It was settled by Greeks during the  7th century bc and was annexed by the Romans, who called it Massilia, in  49 bc. It declined along with the Roman Empire but revived as a commer�  cial port during the Crusades era; it passed to the French crown in 1481. The  plague of 1720 killed half of its population. In the 19th century the devel�  opment of France�s colonial empire added to the city�s importance. Fol�  lowing World War II, rapid industrial growth took place around the port  complex at Fos-sur-Mer and in suburbs such as Marignane and Vitrolles.</p><p>marsh Freshwater or marine wetland ecosystem characterized by poorly  drained mineral soils and by plant life dominated by grasses. Fewer plant  species grow in marshes than on well-watered but not waterlogged land;  grasses, sedges, and reeds or rushes are most common. Commercially, rice  is by far the most important freshwater marsh plant: it supplies a major  portion of the world�s grain. Salt marshes are formed on intertidal land  by seawater flooding and draining, and salt-marsh grasses will not grow  on permanently flooded flats. See also swamp.</p><p>Marsh, Dame (Edith) Ngaio (b.

As  chief of staff of the U.S. Army (1939�45), he directed army operations  throughout World War II. After his retirement in 1945, Pres. Harry Tru�  man sent him to China to mediate the civil war there. As secretary of state  (1947�49), Marshall proposed the European aid program known as the  Marshall Plan and initiated discussions that led to the formation of NATO.  He resigned because of ill health but was called back by Truman to  become secretary of defense (1950-51) and to prepare the armed forces  for the Korean War.

Her short  story �Reena� (1962) was one of the first pieces of fiction to feature a  college-educated, politically active black woman as its protagonist. Her  most eloquent statement of her belief in black Americans� need to redis�  cover their African heritage is the novel Praisesongfor the Widow (1983).

He became the first vice president in nearly 100 years to serve  two terms (1913-21). When Wilson suffered a stroke that partially para�  lyzed him in 1919, Marshall refused to assume the powers of the presi�  dency without a congressional resolution and written requests from first  lady Edith Wilson and the president�s doctor. A popular public official, he  was heard to remark during a tedious debate, �What this country needs  is a really good five-cent cigar.�</p><p>Marshall, Thurgood (b.

From 1936 he worked  for the NAACP, becoming its chief counsel in 1940. He won 29 of the  32 cases he argued before the Supreme Court of the United States, includ�  ing the landmark Brown v. Board of Education (1954) and others that  established equal protection for African Americans in housing, voting,  employment, and education. He served as U.S. solicitor general (1965�  67) before being appointed in 1967 to the Supreme Court by Pres. Lyn�  don B. Johnson, becoming the first African American Supreme Court  justice. Marshall was a steadfast liberal during his tenure on the Court,  and he maintained his previous views concerning the need for equitable  and just treatment of the nation�s minorities by the state and federal gov�  ernments. He retired in 1991.</p><p>Marshall Islands officially Republic of the Marshall Islands</p><p>Island country, central Pacific Ocean. It is composed of two parallel chains  of low-lying coral atolls: the Ratak, or Sunrise, to the east and the Ralik, or  Sunset, to the west. The chains lie 125 mi (200 km) apart and extend some  800 mi (1,290 km) northwest to southeast. The islands and islets number  more than 1,200. Area: 70 sq mi (181 sq km). Population (2005 est.):  56,300. Capital: Majuro. The indigenous people are Micronesian. Lan�  guages: Marshallese, English (both official). Religion: Christianity (Prot�  estant, Roman Catholic, other Christians). Currency: U.S. dollar. The  largest atoll is Kwajalein, consisting of about 90 islets, with a total land area  of 6 sq mi (16 sq km). Much of Kwajalein is used as a missile-testing range  by the U.S. military, which provides a major source of revenue to the Mar�  shall Islands. Subsistence farming, fishing, and the raising of pigs and poul�  try are the principal economic activities. The Marshall Islands is a republic  with two legislative houses; its head of state and government is thejjresi-  dent. The islands were sighted in 1529 by the Spanish navigator Alvaro  Saavedra (or de Saavedra). Germany purchased the islands from Spain in  1885 and declared them a protectorate the following year. Japan seized  them in 1914 and after 1919 administered them as a League of Nations  mandate. During World War II the U.S. seized Kwajalein and Enewetak,  and the Marshall Islands were made part of the UN Trust Territory of the  Pacific Islands under U.S. jurisdiction in 1947. Bikini and Enewetak atolls  served as testing grounds for U.S. nuclear weapons from 1946 to 1958. The  Marshall Islands became an internally self-governing republic in 1979. It  signed the compact of free association with the U.S. in 1982 and became  fully self-governing in 1986. The compact was amended in 2004.</p><p>Marshall Plan (1948-51) U.S.-sponsored program to provide eco�  nomic aid to European countries after World War II. The idea of a Euro�  pean self-help plan financed by the U.S. was proposed by George Marshall  in 1947 and was authorized by Congress as the European Recovery Pro�  gram. It provided almost $13 billion in grants and loans to 17 countries</p><p>and was a key factor in reviving their economies and stabilizing their  political structures.

He helped declare Pope  John XXII a heretic, install Nicholas V as antipope, and crown Louis  emperor (1328).

One of the most vigorous sati�  rists of his era, he wrote all his plays before taking holy orders in 1609.  His best-known work is the tragicomedy The Malcontent (1604), which  rails at the iniquities of a lascivious court. Also notable is The Dutch  Courtezan (produced 1603-04), one of the cleverest comedies of its time.

He later lived in various countries, spending most of 1881-95 in  New York City. He organized and unified the movement for Cuban inde�  pendence and died in battle. As a writer, he is noted for his personal prose  and deceptively simple verse on themes of a free and united America.

He is the national hero of Cuba.</p><p>Martial Vmar-shoR Latin Marcus Valerius Martialis (b. c. ad</p><p>38/41, Bilbilis, Hispania�d. c. 103) Roman poet. Born in a Roman  colony in what is now Spain, Martial went to Rome as a young man. There  he associated with such figures as Seneca, Lucan, and Juvenal and enjoyed  the patronage of the emperors Titus and Domitian. His early poetry, some  marred by gross adulation of Titus, was undistinguished. He is renowned  for his 12 books of epigrams (86-1027), a form he virtually created. Pointed  and often obscene, they provide a picture of Roman society during the  early empire that is remarkable both for its completeness and for its accu�  rate portrayal of human foibles.</p><p>martial art Any of several arts of combat and self-defense that are  widely practiced as sport. There are armed and unarmed varieties, most  based on traditional fighting methods used in East Asia. In modem times,  derivatives of armed martial arts include kendo (fencing with wooden  swords) and kyudo (archery). Unarmed varieties include aikido, judo,  karate, kung fu, and tae kwon do. Because of the influence of Taoism and  Zen Buddhism, there is a strong emphasis in all the martial arts on the  practitioner�s mental and spiritual state. A hierarchy of expertise, ranging  from the novice (�white belt�) to the master (�black belt�), is usually rec�  ognized. See also Y ai chi ch'uan; jujitsu.</p><p>martial law Temporary rule of a designated area by military authori�  ties in time of emergency when the civil authorities are deemed unable  to function. Under martial law, civil rights are usually suspended, and the  activities of civil courts are restricted or supplanted entirely by military  tribunals.

Martin rejected French efforts to persuade  him to live at Avignon (see Avignon papacy). Instead he returned to Rome  (1420), where he helped to rebuild the ruined city. He also tried to recover  control of the Papal States. He mediated in the Hundred Years' War and  organized crusades against the Hussites, and he asserted the rights of the  church against the crown.</p><p>martin Any of several species of songbirds in the family Hirundinidae.

She studied at Colum�  bia University and taught at the University of New Mexico. In 1958 she  had her first solo exhibition. Martin was a prominent exponent of geo�  metric abstraction, and, for her, a gray grid of intersecting penciled lines  became the ultimate geometric composition. Her gridlike abstractions  were also noted for their light-soaked appearance and quiet effect. In the  1970s she produced printed equivalents of her paintings; a notable series  of silkscreens, On a Clear Day (1973), was produced after her math�  ematically annotated sketches. Martin was one of the leading practitio�  ners of Abstract Expressionism in the 20th century.</p><p>Martin, Mary (Virginia) (b. Dec. 1, 1913, Weatherford, Texas,  U.S.�d.

He first attracted attention with the novel Jean Barois (1913),  the story of an intellectual tom between the Roman Catholic faith of his  childhood and the scientific materialism of his maturity. He is best known  for the eight-novel cycle Les Thibault (1922^10), the record of a fami�  ly�s development that chronicles the social and moral issues facing the  French bourgeoisie in the pre-World War I era. He received the 1937  Nobel Prize for Literature.</p><p>Martin of Tours Vtur\, Saint (b. c. 316, Sabaria, Pannonia�d.

He was forced to join the Roman army but asked  to be released because service was incompatible with his Christianity.  After imprisonment he settled in Poitiers and then became a missionary  on the Balkan Peninsula. He returned to Poitiers in 360 and founded the  first monastery in Gaul. In 371 he was made bishop of Tours. A second  monastery he founded, at Mormoutier, became a great monastic complex.

Its capital is Fort-de-France. Tourism is the basis of its economy.  Carib Indians, who had ousted earlier Arawak inhabitants, resided on the  island when Christopher Columbus visited it in 1502. In 1635 a Frenchman  established a colony there, and in 1674 it passed to the French crown. The  British captured and held the island from 1762 to 1763 and occupied it  again during the Napoleonic Wars, but each time it was returned to France.  Made a department of France in 1946, it remained under French rule  despite a communist-led independence movement in the 1970s.</p><p>Martins, Peter (b. Oct. 27, 1946, Copenhagen, Den.) Danish-born U.S.  dancer, choreographer, and director of the New York City Ballet. He trained  at the Royal Danish Ballet School and became a member of its company  in 1965. He joined the New York City Ballet in 1969 as a principal dancer  and created roles in ballets such as Jerome Robbins�s Goldberg Variations  (1971) and George Balanchine�s Duo Concertante (1972). He began cho�  reographing for the company in 1977 with Calcium Light Night. After  Balanchine�s death in 1983, Martins became codirector (until 1990) and  then sole director of the company.</p><p>Martinson, Harry (Edmund) (b. May 6, 1904, Jamshog, Swed.�d.  Feb. 11, 1978, Stockholm) Swedish novelist and poet. He spent his child�  hood in foster homes and his young adulthood as a merchant seaman,  labourer, and vagrant. He described his early experiences in two autobio�  graphical novels. Flowering Nettle (1935) and The Way Out (1936), and  in travel sketches. Among his best-known works are the poetry collection  Trade Wind (1945), the novel The Road (1948), and the epic poem Ani-  ara (1956). In 1949 he became the first self-taught working-class writer  ever elected to the Swedish Academy.

Czech (Bohemian) com�  poser. He started composing at age 10 but was expelled from the conser�  vatory for neglecting his studies. His early pieces combined the influences  of Czech folk music and French composer Claude Debussy�s music. In Paris  (1923^40) he gained a reputation for his colourful ballet scores and  experimented with Neoclassicism, jazz, and ragtime. He composed many  works, including six symphonies, operas (including Julietta, 1938), and  large choral works (including The Epic of Gilgamesh, 1955), but he did  little to promote his music.</p><p>Martov Vmar-.tofX, L. orig. Yuly Osipovich Tsederbaum (b. Nov.  24, 1873, Constantinople, Ottoman Empire�d. April 4, 1923, Berlin,  Ger.) Russian revolutionary. He first lived in Vilna, where he belonged to  the Bund, a Jewish socialist group. In 1895 he and Vladimir Ilich Lenin  formed the St. Petersburg Union of Struggle for the Liberation of the  Working Class. After his arrest and exile to Siberia (1896-99), he joined  Lenin in Switzerland as an editor of Iskra. From 1903 Martov supported  the Menshevik faction of the Russian Social-Democratic Workers' Party and  became its leader (1905-07). After the Russian Revolution of 1917, he  supported the Bolshevik government in the Russian Civil War but later  opposed many of its dictatorial measures. He left Russia in 1920 and  edited the Socialist Courier in Berlin.</p><p>martyr Person who voluntarily suffers death rather than deny his or her  religion. Readiness for martyrdom was a collective ideal in ancient Juda�</p><p>ism, notably in the era of the Maccabees, and its importance has contin�  ued into modern times. Roman Catholicism sees the suffering of martyrs  as a test of their faith. Many saints of the early church underwent mar�  tyrdom during the persecutions of the Roman emperors. Martyrs need not  perform miracles to be canonized. In Islam, martyrs are thought to com�  prise two groups of the faithful: those killed in jihad and those killed  unjustly. In Buddhism, a bodhisattva is regarded as a martyr because he  voluntarily postpones enlightenment to alleviate the suffering of others.</p><p>Marvell Vmar-volV Andrew (b.

He  was employed as a tutor, including to Oliver Cromwell�s ward, before  becoming an assistant to John Milton in the foreign office in 1657. From  1659 he held a seat in Parliament. His reputation as one of the finest secu�  lar Metaphysical poets (see Metaphysical poetry) is based on a small body  of brilliant lyric verse, notably �To His Coy Mistress� (1681) and �The  Garden.� Among his other works are classical odes, such as �An Hora-  tian Ode upon Cromwell�s Return from Ireland� (1650); political verse  satires opposing the government after the Restoration, such as Last  Instructions to a Painter (1667); and prose satires.</p><p>Marx, Karl (Heinrich) (b. May 5, 1818, Trier, Rhine province, Prus�  sia [Ger.]�d. March 14, 1883, London, Eng.) German political philoso�  pher, economic theorist, and revolutionary. He studied humanities at the  University of Bonn (1835) and law and philosophy at the University of  Berlin (1836�41), where he was exposed to the works of G.W.F. Hegel.  Working as a writer in Cologne and Paris (1842^15), he became active  in leftist politics. In Paris he met Friedrich Engels, who would become his  lifelong collaborator. Expelled from France in 1845, he moved to Brus�  sels, where his political orientation matured and he and Engels made  names for themselves through their writings. Marx was invited to join a  secret left-wing group in London, for which he and Engels wrote the  Communist Manifesto (1848). In that same year, Marx organized the first  Rhineland Democratic Congress in Germany and opposed the king of  Prussia when he dissolved the Prussian Assembly. Exiled, he moved to  London in 1849, where he spent the rest of his life. He worked part-time  as a European correspondent for the New York Tribune (1851-62) while  writing his major critique of capitalism, Das Kapital (3 vol., 1867-94). He  was a leading figure in the First International from 1864 until the defec�  tion of Mikhail Bakunin in 1872.

Zeppo left the act in 1934, and the act disbanded in 1949. Grou�  cho later hosted the television quiz program You Bet Your Life (1950-61).</p><p>Marxism Ideology and socioeconomic theory developed by Karl Marx  and Friedrich Engels. The fundamental ideology of communism, it holds that  all people are entitled to enjoy the fruits of their labour but are prevented  from doing so in a capitalist economic system, which divides society into  two classes: nonowning workers and non working owners. Marx called  the resulting situation �alienation,� and he said that when the workers  repossessed the fruits of their labour, alienation would be overcome and  class divisions would cease. The Marxist theory of history posits class  struggle as history�s driving force, and it sees capitalism as the most recent  and most critical historical stage�most critical because at this stage the  proletariat will at last arise united. The failure of the European Revolutions  of 1 848 and an increasing need to elaborate on Marxist theory, whose  orientation is more analytical than practical, led to adaptations such as  Leninism and Maoism; in the late 20th century the collapse of the Soviet  Union and China�s adoption of many elements of a free-market economy  seemed to mark the end of Marxism as an applicable economic or gov�  ernmental theory, though it retains interest as a critique of market capi�  talism and a theory of historical change.

According to the Gospels, she was betrothed to St.  Joseph when the archangel Gabriel appeared to her to announce the com�  ing birth of Jesus. Other incidents in the Gospels in which she appears  include the visit to Elizabeth, mother of John the Baptist; the birth of Jesus  and his presentation in the Temple; the coming of the Magi and the flight  to Egypt; the marriage at Cana in Galilee; the attempt to see Jesus while  he was teaching; and watching at the cross. Eastern Orthodoxy, Roman  Catholicism, and most Protestant denominations hold Jesus to have been  divinely conceived and Mary to have remained a virgin. The Roman  Catholic church also holds to the doctrine of her Immaculate Conception  and her bodily assumption into heaven. Catholics pray to Mary as an  intercessor.

The  daughter of King Henry VIII and Catherine of Aragon, she was declared  illegitimate after Henry�s divorce and new marriage to Anne Boleyn  (1533). In 1544 Mary was restored to court and granted succession to the  throne. After becoming queen (1553), she married Philip II of Spain,  restored Roman Catholicism, and revived the laws against heresy. The  resulting persecution of Protestant rebels and the execution of some 300  heretics earned her the hatred of her subjects and the nickname �Bloody  Mary.� She waged an unsuccessful war against France that in 1558  resulted in the loss of Calais, England�s last foothold on the Continent.</p><p>Mary II (b. April 30, 1662, London, Eng.�d. Dec. 28, 1694, London)  Queen of England (1689-94). The daughter of King James II, a Catholic  convert, she was reared as a Protestant and in 1677 married to her cousin,  William of Orange. They lived in Holland until English nobles opposed  to James�s pro-Catholic policies invited William and Mary to assume the  English throne. After William landed with a Dutch force (1688), James  fled, and Mary and William (as King William III) became corulers of  England (1689). Mary enjoyed great popularity, and her Dutch tastes had  an influence on English pottery, landscape gardening, and interior design.  She died of smallpox at age 32.</p><p>Mary, Queen of Scots orig. Mary Stuart (b. Dec. 8, 1542, Lin�  lithgow Palace, West Lothian, Scot.�d. Feb. 8, 1587, Fotheringhay  Castle, Northamptonshire, Eng.) Queen of Scotland (1542-67). She  became queen when her father, James V (1512-42), died six days after  her birth. She was sent by her mother, Mary of Guise, to be raised at the  court of the French king Henry II and was married in 1558 to his son Fran�  cis II. After Francis�s brief rule as king (1559-60) ended with his prema�  ture death, Mary returned to Scotland (1561), where she was distrusted</p><p>because of her Catholic upbringing. In 1565 the red-haired queen married  her ambitious cousin Henry Stewart, Lord Darnley, and became a victim  of intrigues among the Scottish nobles. Darnley conspired with them to  murder her confidant David Riccio. After the birth of her son James (later  James I of England) in 1566, Mary was estranged from Darnley, who was  murdered in 1567. Ignoring objections by the jealous Scottish nobility,  she married James Hepburn, earl of Bothwell (15357-78), a suspect in  Darnley�s murder. The rebellious nobles deserted her army at Carberry  Hill and forced her to abdicate in favour of her son (1567). After failed  attempts to win back the throne, she sought refuge in England with her  cousin Elizabeth I, who arranged to keep her in captivity. Several uprisings  by English Catholics in Mary�s favour convinced Elizabeth to have Mary  tried and condemned; she was beheaded at Fotheringhay Castle in 1587.</p><p>Mary Magdalene, Saint (fl. 1st century, Palestine; feast day July  22) Follower of Jesus and the first person to see the resurrected Christ.

On Easter morning she went with two other women to  anoint the corpse, but the tomb was empty. Christ later appeared to her  and instructed her to tell the Apostles that he was ascending to God. Popu�  lar tradition has long associated her with the repentant prostitute who  anointed Christ�s feet.</p><p>Maryinsky Theatre See Mariinsky Theatre</p><p>Maryland State (pop., 2000: 5,296,486), eastern U.S. A Middle Atlan�  tic state, it is deeply indented by Chesapeake Bay and is bordered by Penn�  sylvania, Delaware, Virginia, the District of Columbia, and West Virginia.  It covers 10,460 sq mi (27,091 sq km); its capital is Annapolis. The state�s  main geographic regions are the coastal plain along Chesapeake Bay, the  rich farming country of the Piedmont plateau, and the Appalachian Moun�  tains. First occupied by late Ice Age hunters c. 10,000 bc, the area was  later inhabited by the Nanticoke and Piscataway tribes. Capt. John Smith  charted the Chesapeake Bay region in 1608. Maryland was included in a  charter given by the British king to Cecil Calvert, Lord Baltimore.  Leonard Calvert, his brother, founded the first settlement in 1634 at St.  Marys City. Maryland became the first American colony to establish reli�  gious freedom. Its boundary dispute with Pennsylvania was settled in the  1760s with the drawing of the Mason-Dixon Line. In 1788 Maryland  became the seventh state to ratify the U.S. Constitution. The state ceded  the District of Columbia as the site for a new federal capital in 1791. It was  involved in the War of 1812 (see Fort McHenry). The U.S. Naval Acad�  emy was founded at Annapolis in 1845. Maryland remained in the Union  during the American Civil War, but strong Southern sentiments resulted in  the imposition of martial law. After the war, it prospered as an important  entrepot for consumer goods to the South and Midwest. During the 20th  century its proximity to the national capital spurred population growth.  Its economy is based primarily on government services and manufactur�  ing.</p><p>Masaccio \m3- , za-che-,o\ orig. Tommaso di Giovanni di  Simone Guidi (b.

He went to  Rome in 1428 and died there so suddenly that some people suspected he  had been poisoned. The rationality, realism, and humanity of the art he  created in his brief six years of work inspired the major Florentine Renais�  sance painters of the mid-15th century and ultimately influenced the  course of Western painting.</p><p>Masada \m9-'sa-d3\ Ancient mountain fortress, southeastern Israel. It  occupies the entire top of a mesa, which is 1,424 ft (434 m) tall and has an  area of 18 acres (7 hectares). Its fortifications were built by Herod the Great  in the 1st century bc; it was captured by the Zealots, a Jewish sect, in their  revolt against Rome in ad 66. After the fall of Jerusalem, Masada, the last  remnant of Jewish rule in Palestine, refused to surrender. In 73, after a  lengthy siege, it was finally taken by the Romans, who found that nearly all  of the some 1,000 Zealots there had committed suicide rather than be cap�  tured. In the 20th century, the fortress became a symbol of Jewish national  heroism; it is now one of Israel�s most visited tourist attractions.</p><p>Masai or Maasai \ma-'sl\ Nomadic herders of southern Kenya and  northern Tanzania.

After receiving a doctorate from the  University of Vienna, he taught philosophy at the Czech University of  Prague (1882) and wrote on the Czech Reformation; his most important  works were a study of Marxism (1898) and Russia and Europe (1913).  In the Austrian Reichsrat (1891-93, 1907-14), he supported democratic  policies and criticized Austria-Hungary�s alliance with Germany. In 1915  he went to western Europe, where he organized the Czech national coun�  cil, which in 1918 gained recognition as the de facto government of the  future Czechoslovakia. He negotiated its liberation as one of the Fourteen  Points in the projected post-World War I peace settlement.

May 15, 1909,</p><p>Huddersfield, Yorkshire, Eng.�d.</p><p>July 27, 1984, Lausanne, Switz.)</p><p>British film actor. After studying architecture at the University of Cam�  bridge, he made his screen debut in Late Extra (1935) and soon became  a star in British films such as The Man in Grey (1943), The Seventh Veil  (1945), and Odd Man Out (1947). He moved to Hollywood in the late  1940s but continued to make films in Britain as well. Noted for his urbane  characterizations of flawed individuals, he appeared in more than 100  movies, including Madame Bovary (1949), A Star Is Born (1954), North  by Northwest (1959), Lolita (1962), Georgy Girl (1966), The Boys from  Brazil (1978), and The Verdict (1982).</p><p>Mason, James Murray (b. Nov. 3, 1798, Fairfax county, Va.,  U.S.�d. April 28, 1871, Alexandria, Va.) U.S. politician. A grandson of  George Mason, he practiced law in his native Virginia from 1820. He  served in the state legislature (1826, 1828-32), the U.S. House of Rep�  resentatives (1837-39), and the U.S. Senate (1847-61). An advocate of  secession, he resigned his Senate seat in 1861. Appointed Confederate  commissioner to England, he was captured at sea with John Slidell aboard  the Trent and imprisoned for two months (see Trent Affair). Released in  1862, he remained in England until 1865 but was unable to win support  for the Confederate cause.</p><p>Mason-Dixon Line Originally, the boundary between Maryland and  Pennsylvania. The 233-mi (375-km) line was surveyed by Charles Mason  and Jeremiah Dixon in 1765-68 to define the disputed boundaries between  the land grants of the Penns, proprietors of Pennsylvania, and the Balti-  mores, proprietors of Maryland. The term was first used in congressional  debates leading to the Missouri Compromise (1820) to describe the divid�</p><p>ing line between the slave states to its south and the free-soil states to its  north. It is still used as the figurative dividing line between the North and  South.</p><p>masonry Craft of building in stone, brick, or block. By 4000 bc, Egypt  had developed an elaborate cut-stone technique. In Crete, Italy, and  Greece, cyclopean work overcame material weaknesses by using enor�  mous irregularly shaped stones without mortal', thereby reducing the num�  ber of joints. African stonemasons also were skilled at mortarless work,  and Japanese mortarless castle walls resisted collapse during earthquakes.  The Roman inventions of concrete and mortar permitted the development  of the arch into one of the basic construction forms and gave rise to a  number of variations in the facing used for walls: squared stone blocks,  concrete studded with rough stones, concrete with diagonal stone courses,  brick- and tile-faced concrete, and mixed brick and stone. The Assyrian  and Persian empires, which lacked stone outcroppings, used sun-dried  clay bricks. Stone and clay were the primary masonry materials in the  Middle Ages and later. Precast-concrete blocks, often used as infill in  modern steel framing, did not effectively compete with brick until the 20th  century. Brick and block are often combined or used in cavity walls. Glass-  block walls, which utilize steel rods to reinforce the mortar joints, admit  light and afford greater protection against intruders and vandals than ordi�  nary glass.

It  originated in the folk ceremony known as mummery (see mumming play)  and evolved into elaborate court spectacles in the 16th-17th centuries. A  masque presented an allegorical theme using speeches, dances, and songs,  in a performance often embellished with rich costumes and spectacular  scenery. The genre reached its height in 17th-century England when the  court poet, Ben Jonson, collaborating with Inigo Jones on many notable  masques (1605-34), gave it literary force. The masque later developed  into OPERA.</p><p>mass Quantitative measure of inertia, or the resistance of a body to a  change in motion. The greater the mass, the smaller is the change pro�  duced by an applied force. Unlike weight, the mass of an object remains  constant regardless of its location. Thus, as a satellite moves away from  the gravitational pull of the Earth, its weight decreases but its mass  remains the same. In ordinary, classical chemical reactions, mass can be  neither created nor destroyed. The sum of the masses of the reactants is  always equal to the sum of the masses of the products. For example, the  mass of wood and oxygen that disappears in combustion is equal to the  mass of water vapour, carbon dioxide, smoke, and ash that appears. How�  ever, Albert Einstein�s special theory of relativity shows that mass and  energy are equivalent, so mass can be converted into energy and vice  versa. Mass is converted into energy in nuclear fusion and nuclear fission.  In these instances, conservation of mass is seen as a special case of a  more general conservation of mass-energy. See also critical mass.</p><p>mass Celebration of the Eucharist in the Roman Catholic church. It is  considered a sacramental reenactment of the death and resurrection of  Jesus as well as a true sacrifice in which the body and blood of Jesus (the  bread and wine) are offered to God. It is also seen as a sacred meal that  unifies and nourishes the community of believers. The mass includes  readings from Scripture, a sermon, an offertory, a eucharistic prayer, and  communion. The rite was greatly changed after the Second Vatican Coun�  cil, notably in the adoption of vernacular languages in place of Latin. See  also SACRAMENT, TRANSUBSTANTIATION.</p><p>mass action, law of Fundamental law of chemical kinetics (the study  of rates of chemical reactions), formulated in 1864-79 by the Norwegian  scientists Cato M. Guldberg (1836-1902) and Peter Waage (1833-1900).  The law states that the reaction rate of any simple chemical reaction is  proportional to the product of the molar concentrations of the reacting  substances, each raised to the power corresponding to the number of mol�  ecules of that substance in the reaction.</p><p>mass-energy equation See Einstein's mass-energy relation</p><p>mass flow or convection In physiology, the mechanism responsible  for movement of air from the atmosphere into the lungs and for move�  ment of blood between the lungs and the tissues.

The term mass wasting refers only to gravity-driven pro�  cesses that move large masses of earthen material from one place to  another. The term mass movement includes the sinking of confined areas.</p><p>mass production Application of the principles of specialization, divi�  sion of labour, and standardization of parts to the manufacturing of goods  on a large scale. Modem mass-production methods have led to such  improvements in the cost, quality, quantity, and variety of goods available  that the largest global population in history is now sustained at the high�  est general standard of living ever. The requirements for mass production  of a particular product include the existence of a market large enough to  justify a large investment; a product design that can use standardized parts  (see interchangeable parts) and processes; a physical layout that minimizes  materials handling; division of labour into simple, short, repetitive steps  (see time-and-motion study); continuous flow of work; and tools designed  specifically for the tasks to be performed. See also assembly line.</p><p>mass spectrometry or mass spectroscopy Analytic technique  by which chemical substances are identified by sorting gaseous ions by  mass using electric and magnetic fields. A mass spectrometer uses electri�  cal means to detect the sorted ions, while a mass spectrograph uses pho�  tographic or other nonelectrical means; either device is a mass  spectroscope. The process is widely used to measure masses and relative  abundances of different isotopes, to analyze products of a separation by  liquid or gas chromatography, to test vacuum integrity in high-vacuum  equipment, and to measure the geological age of minerals.</p><p>mass transit Transportation systems, usually publicly but sometimes  privately owned and operated, designed to move large numbers of people  in various types of vehicles in cities, suburbs, and large metropolitan  areas. Modern mass transit is an outgrowth of industrialization and urban�  ization. In the 1830s early mass transit in New York City included horse-  drawn buses, which were soon replaced by fixed-rail horse-drawn trolleys.  By 1900 motorized Buses had appeared in Europe and America. With the  advent of electricity, streetcars and subways were introduced in many large  cities. In the 20th century the automobile�s increasing popularity under�  mined mass transit development; fixed-rail streetcar systems were widely  removed to provide space for cars. Concern over air pollution has revived  interest in light-rail transit and has led to regional mass transit systems.</p><p>Massachusetts officially Commonwealth of Massachusetts</p><p>State (pop., 2000: 6,349,097), northeastern U.S. One of the New England  states, it lies on the Atlantic Ocean and is bordered by Vermont, New  Hampshire, Rhode Island, Connecticut, and New York. It covers 8,262 sq  mi (21,399 sq km); its capital is Boston. The state�s soils are poor and  rocky, and agriculture plays a limited role in the economy, although cran�  berry farming is important. The region was inhabited by Algonquian  Indian peoples when the first English settler, Bartholomew Gosnold,  arrived in 1602. Plymouth was settled by the Pilgrims, who arrived on the  Mayflower in 1620. The Massachusetts Bay Colony was founded and gov�  erned by the Massachusetts Bay Co., spurring Puritan settlement. It joined  the New England Confederation in 1643 and acquired Maine in 1652. The  southeastern and central settlements in the state experienced King Philip's  War in 1675. After losing its first charter in 1684, it became part of the  Dominion of New England in 1686. Its second charter in 1691 granted  the colony jurisdiction over Maine and Plymouth. In the 18th century  Massachusetts became a centre of resistance to British colonial policy; it  was the scene of the Boston Tea Party and of uprisings at the Battles of  Lexington and Concord that marked the beginning of the American Revo�  lution. In 1788, it became the sixth state to ratify the U.S. Constitution. It  was in the forefront of the 19th century Industrial Revolution and was  known for its textile mills. Today its major industries are electronics, high  technology, and communications. It is well-known as the location of many  institutions of higher learning. Tourism is important especially in the Cape  Cod region and the Berkshires.</p><p>Massachusetts Bay Colony Early English colony in Massachusetts.  It was settled in 1630 by a group of 1,000 Puritan refugees from England  (see Puritanism). In 1629 the Massachusetts Bay Co. had obtained an  English charter allowing it to trade and colonize in New England. Puri�  tan stockholders envisioned the colony as a refuge from religious perse�</p><p>cution in England, and they transferred control of the company to the  emigrants in Massachusetts. Led by John Winthrop, the colonists founded  their colony on the Charles River at what would become Boston. In 1684  England annulled the company�s charter and in 1691 established royal  government under a new charter, which merged Plymouth colony and  Maine into the Massachusetts Bay Colony.</p><p>Massachusetts Institute of Technology (MIT) U.S. private uni�  versity in Cambridge, famous for its scientific and technological training  and research. Founded in 1861, MIT has schools of architecture and plan�  ning, engineering, humanities and social sciences, management (the Sloan  School), and science and a college of health sciences and technology.  Though it is best known for its programs in engineering and the physical  sciences, other areas such as economics, political science, urban studies,  linguistics, and philosophy are also strong. Among its facilities are a  nuclear reactor, a computation centre, geophysical and astrophysical  observatories, a linear accelerator, a space research centre, supersonic  wind tunnels, an artificial-intelligence laboratory, a centre for cognitive  science, and an international-studies centre.</p><p>massage \m9-'sazh\ Systematic, scientific manipulation of body tissues  with the hands to relieve pain and reduce swelling, relax muscles, and  speed healing after strains and sprains. It has been used for more than  3,000 years by the Chinese. Early in the 19th century, the Swedish phy�  sician Per Henrik Ling (1776-1839) devised a massage system for joint  and muscle ailments, which was later extended to relieve deformities of  arthritis and re-educate muscles following paralysis. Manipulations  include light or hard stroking, compression (kneading, squeezing, and  friction), and percussion (striking with the edges of the hands in rapid  alternation). In acupressure, a style of massage derived from China, pres�  sure is exerted on Chinese acupuncture points for healing effects.

In campaigns  against the Austrians in Italy, he became Napoleon�s most trusted officer;  he then commanded the French army in Switzerland, defeating the Rus�  sians at Zurich (1799). Sent by Napoleon to restore the demoralized army  of Italy, he successfully defended Genoa against Austrian besiegers and  enabled the French victory at the Battle of Marengo. He was made a mar�  shal in 1804 and duke de Rivoli in 1808. He displayed heroism against  the Austrians, notably at Aspem-Essling and the Battle of Wagram (1809),  and Napoleon made him prince d�Essling (1810). In command of the  French forces in Portugal and Spain (1810-11), he was defeated by the  British under the duke of Wellington.

When his fam�  ily left Paris in 1854, he ran away to continue his studies, playing piano  and drums and teaching to support himself. His hard work paid off when  he won the Prix de Rome in 1863, and he began writing operas in 1867.  His reputation was established with his oratorio Marie-Magdeleine  (1873), and his Le Roi de Lahore was performed at the Paris Opera in  1877. There followed the series of successes for which he is chiefly  known, including Herodiade (1881), Manon (1884), Le Cid (1885),  Esclarmonde (1889), Werther (1892), Thai's (1894), and Don Quichotte</p><p>(1910).</p><p>Massey, (Charles) Vincent (b.

He joined  the Surrealist movement in 1924 and became the leading practitioner of  automatism. In the late 1920s and �30s he produced turbulent images of  violence, psychic pain, eroticism, and physical metamorphosis, using  sinuous lines to delineate abstract biomorphic forms. He lived in Spain  (1934-36) and later the U.S. (1941�45), where he became an important  link between Surrealism and Abstract Expressionism.

Most of the techniques used by modern matadors were estab�  lished in the 1910s by Juan Belmonte (b. 1894-d. 1962) of Spain. The  matador�s traditional costume, which offers no protection, is known as</p><p>the �suit of lights.� The audience judges the matador according to his skill,  grace, and daring. Almost every matador is gored at least once a season  with varying degrees of severity, and many have received fatal wounds  in the ring.</p><p>Matamba \ma-'tam-b3\ Historic African kingdom of the Mbundu  people, located northeast of Luanda, Angola. A strong state in the early  16th century, it came into conflict with the Portuguese colonists of Angola.  About 1630 it was conquered by Nzinga, ex-ruler of Ndongo, who  strengthened it and stopped Angola�s eastward expansion in the 1670s. A  1684 treaty remained in effect until the Portuguese seized part of Mata�  mba�s territory in 1744. The rest of it, assigned to Angola by European  treaties of 1870-1900, remained a self-governing kingdom until it was  occupied by Portuguese troops in the early 20th century.</p><p>Matamoros City (pop., 2000: 376,279), northern Tamaulipas state,  Mexico. It is situated on the southern bank of the Rio Grande, across from  Brownsville, Texas, U.S. Founded in 1824, it was the scene of bitter fight�  ing in the Mexican War and was occupied by U.S. troops in 1846. It is now  one of Mexico�s chief ports of entry for tourists and a trade centre.</p><p>Matapedia X.ma-to-'pe-de-oX Valley Valley of the Notre Dame Moun�  tains, Gaspe Peninsula, eastern Quebec province, Canada. Extending for  some 60 mi (100 km), it forms a direct lowland route through the moun�  tains from the St. Lawrence River to the Atlantic coast. It serves as an  important transportation route between the Maritime Provinces and the  Canadian mainland. It is drained by the Matapedia River, which flows 50  mi (80 km) to join the Restigouche River.</p><p>Mata ram Xmo-'ta-ronA Historic kingdom, Java. Originally a vassal state  of Pajang, it became powerful under Senapati, who became its first king  in the late 16th century. Its territory expanded in the early 17th century,  but the kingdom later began to decline. In the mid-18th century it lost  both power and territory to the Dutch East India Co., and was a vassal  state of the company by 1749. Wars of succession in 1755 led to its divi�  sion into the regions of Surakarta and Yogyakarta.</p><p>matchlock Device for igniting gunpowder, invented in the 15th cen�  tury.

In the philosophy of mind, one form of material�  ism, sometimes called central-state materialism, asserts that states of the  mind are identical to states of the human brain. In order to account for  the possible existence of mental states in creatures that do not share the  human nervous system (e.g., octopuses and Martians), proponents of func�  tionalism identified particular mental states with the functional or causal  roles those states play with respect to other physical and mental states of  the organism; this allows for the �multiple realizability� of the same men�  tal state in different physical states. (Strictly speaking, functionalism is  compatible with both materialism and non-materialism, though most func�  tionalists are materialists.) As a form of materialism, functionalism is  �nonreductive,� because it holds that mental states cannot be completely  explained in terms that refer only to what is physical. Though not iden�  tical with physical states, mental states are said to �supervene� on them,  in the sense that there can be no change in the former without some change  in the latter. �Eliminative� materialism rejects any aspect of the mental  that cannot be explained wholly in physical terms; in particular, it denies  the existence of the familiar categories of mental state presupposed in folk  psychology. See also identity theory; mind-body problem.</p><p>materials science Study of the properties of solid materials and how  those properties are determined by the material�s composition and struc�  ture, both macroscopic and microscopic. Materials science grew out of  solid-state physics, metallurgy, ceramics, and chemistry, since the numer�  ous properties of materials cannot be understood within the context of  any single discipline. With a basic understanding of the origins of prop�  erties, materials can be selected or designed for an enormous variety of  applications, from structural steels to computer microchips. Materials sci�  ence is therefore important to many engineering fields, including electron�  ics, aerospace, telecommunications, information processing, nuclear  power, and energy conversion. See also mechanics, metallography, strength  OF MATERIALS, TESTING MACHINE.</p><p>mathematical physics Branch of mathematical analysis that empha�  sizes tools and techniques of particular use to physicists and engineers. It  focuses on vector spaces, matrix algebra, differential equations (especially  for boundary value problems), integral equations, integral transforms, infi�  nite series, and complex variables. Its approach can be tailored to applica�  tions in electromagnetism, classical mechanics, and quantum mechanics.</p><p>mathematical programming Application of mathematical and  computer programming techniques to the construction of deterministic  models, principally for business and economics. For models that only  require linear algebraic equations, the techniques are called linear pro�  gramming; for models that require more complex equations, it is called  nonlinear programming. In either case, models frequently involve hun�  dreds or thousands of equations. The discipline emerged during World  War II to solve large-scale military logistics problems. Mathematical pro�  gramming is also used in planning civilian production and transportation  schedules and in calculating economic growth.</p><p>mathematics Science of structure, order, and relation that has evolved  from counting, measuring, and describing the shapes of objects. It deals  with logical reasoning and quantitative calculation. Since the 17th cen�  tury it has been an indispensable adjunct to the physical sciences and  technology, to the extent that it is considered the underlying language of  science. Among the principal branches of mathematics are algebra, analy�  sis, arithmetic, combinatorics, Euclidean and non-Euclidean geometries, game</p><p>THEORY, NUMBER THEORY, NUMERICAL ANALYSIS, OPTIMIZATION, PROBABILITY, SET THEORY,  STATISTICS, TOPOLOGY, and TRIGONOMETRY.</p><p>mathematics, foundations of Scientific inquiry into the nature of  mathematical theories and the scope of mathematical methods. It began  with Euclid�s Elements as an inquiry into the logical and philosophical basis  of mathematics�in essence, whether the axioms of any system (be it Euclid�  ean geometry or calculus) can ensure its completeness and consistency. In  the modern era, this debate for a time divided into three schools of thought:  logicism, formalism, and intuitionism. Logicists supposed that abstract math�  ematical objects can be entirely developed starting from basic ideas of sets  and rational, or logical, thought; a variant of logicism, known as math�  ematical Platonism, views these objects as existing external to and indepen�  dent of an observer. Formalists believed mathematics to be the  manipulation of configurations of symbols according to prescribed rules, a  �game� independent of any physical interpretation of the symbols. Intu-  itionists rejected certain concepts of logic and the notion that the axiomatic</p><p>method would suffice to explain all of mathematics, instead seeing math�  ematics as an intellectual activity dealing with mental constructions (see  constructivism) independent of language and any external reality. In the  20th century, Godel's theorem ended any hope of finding an axiomatic basis  of mathematics that was both complete and free from contradictions.</p><p>mathematics, philosophy of Branch of philosophy concerned with  the epistemology and ontology of mathematics. Early in the 20th century,  three main schools of thought�called logicism, formalism, and  intuitionism �arose to account for and resolve the crisis in the foundations  of mathematics. Logicism argues that all mathematical notions are reduc�  ible to laws of pure thought, or logical principles; a variant known as math�  ematical Platonism holds that mathematical notions are transcendent Ideals,  or Forms, independent of human consciousness. Formalism holds that  mathematics consists simply of the manipulation of finite configurations of  symbols according to prescribed rules; a �game� independent of any physi�  cal interpretation of the symbols. Intuitionism is characterized by its rejec�  tion of any knowledge- or evidence-transcendent notion of truth. Hence,  only objects that can be constructed (see constructivism) in a finite number  of steps are admitted, while actual infinities and the law of the excluded  middle (see laws of thought) are rejected. These three schools of thought  were principally led, respectively, by Bertrand Russell, David Hilbert, and the  Dutch mathematician Luitzen Egbertus Jan Brouwer (1881-1966).</p><p>Mather Vma-thorV Cotton (b.

Her brother�s death in  1120 left her as Henry I�s sole legiti�  mate heir, and Henry named her as  his successor in 1127. Stephen of  Blois, Henry�s nephew, seized the  throne on the king�s death in 1135,  and his army defeated Matilda�s sup�  porters in 1141.

A close friend of Pope  Gregory VII, she backed him in his  struggle against King Henry IV (see  Investiture Controversy), and it was at  her castle at Canossa that the king  performed his barefoot penance  before Gregory (1077). After Hen�  ry�s second excommunication, she  was intermittently at war with him  until his death (1106), sometimes donning armour to lead her own troops,  and she helped finance the pope�s military operations and encouraged  Henry�s son Conrad to rebel against his father (1093).

Dec. 31, 1869, Le  Cateau, Picardy, Fr.�d. Nov. 2, 1954, Nice) French painter, sculptor, and  graphic artist. He was a law clerk when he became interested in art. After  study with Gustave Moreau at the Ecole des Beaux-Arts, he exhibited four</p><p>paintings at the Salon and scored a triumph when the government bought  his Woman Reading (1895). Self-confident and venturesome, he experi�  mented with pointillism but eventually abandoned it in favour of the swirls  of spontaneous brushwork and riots of colour that became known as Fau-  vism. Though his subjects were largely domestic and figurative, his works  exhibit a distinctive Mediterranean verve. He also took up sculpture and  would produce some 60 pieces during his lifetime. The Armory Show  exhibited 13 of his paintings. In 1917 he moved to the French Riviera,  where his paintings became less daring but his output remained prodigious.  After 1939 he became increasingly active as a graphic artist and in 1947  published Jazz, a book of reflections on art and life with brilliantly coloured  illustrations made by �drawing with scissors�: the motifs were pasted  together after being cut out of sheets of coloured paper. He was ill during  most of his last 13 years; he designed the magnificent Chapelle du Rosaire  at Vence (1948�51) as a gift to the Dominican nuns who cared for him.

In 1748  Mato Grosso became an independent captaincy, in 1822 a province of the  empire, and in 1889 a state of the federal union. One of the few great  frontier regions still in existence, it consists of grassland, dense forest,  and highland plains, with some areas that remain largely unexplored.</p><p>matriarchy \'ma-tre-,ar-ke\ Social system in which familial and politi�  cal authority is wielded by women. Under the influence of Charles Dar�  win�s theories of evolution and, particularly, the work of the Swiss  anthropologist Johann Jakob Bachofen (b. 1815, Basel, Switz.�d. 1887,  Basel), some 19th-century scholars believed that matriarchy followed a  stage of general promiscuity and preceded male ascendancy (patriarchy)  in human society�s evolutionary sequence. Like other elements of the  evolutionist view of culture, the notion of matriarchy as a universal stage  of development is now generally discredited, and the modern consensus  is that a strictly matriarchal society has never existed. Nevertheless, in  those societies in which matrilineal descent occurs, access to socially pow�  erful positions is mediated through the maternal line of kin.

Its outlying territories are Rodrigues  Island to the east, the Cargados Carajos  Shoals to the northeast, and the Agalega  Islands to the north. Area: 788 sq mi (2,040  sq km). Population (2005 est.): 1,245,000. Capital: Port Louis. About two-  thirds of the population are of South Asian descent, and most of the rest  are of mixed European, South Asian, and African ancestry. Languages:  English (official), Creole (lingua franca), various ethnic languages. Reli�  gions: Hinduism, Christianity, Islam. Currency: Mauritian rupee. Volca�  nic in origin and almost surrounded by coastal reefs, Mauritius rises to  2,710 ft (826 m) at Petite Riviere Noire Peak. The chief water source is  Lake Vacoas. About half of the land is arable; sugarcane is the major crop,  though the government has sponsored agricultural diversification. The  country depends heavily on food imports, mainly rice. The population  density is one of the highest in the world. The island was visited, but not  settled, by the Portuguese in the early 16th century. The Dutch took pos�  session (1598-1710), called it Mauritius for the governor Maurice of  Nassau, and attempted to settle it (1638-58, 1664-1710) before abandon�</p><p>ing it to pirates. The French East India Company occupied it, renamed it  lie de France in 1721, and governed it until the French Ministry of Marine  took over its administration in 1767. Sugar planting was the main eco�  nomic activity, and the colony prospered. The British captured the island  in 1810 and were granted formal control of it under the Treaty of Paris in  1814; the name Mauritius was reinstated and slavery abolished. In the  late 19th century, competition from beet sugar caused an economic  decline, compounded by the opening of the Suez Canal in 1869. After  World War II Mauritius adopted political and economic reforms, and in  1968 it became an independent state within the Commonwealth. In 1992  it became a republic. It has successfully diversified its economy, notably  into clothing manufacturing.</p><p>Maurois \mbr-'wa\, Andre orig. Emile Herzog (b. July 26, 1885,  Elbeuf, France�d.

Suc�  ceeding his father as duke, he restored the duchy to solvency, revised the  law code, and built an effective army. Opposed to the Protestant cause,  he established the Catholic League (1610). In the Thirty Years' War he gave  military aid to Austria against the Palatine elector Frederick V and, with  military victories by count von Tilly, obtained both territory and the elec�  torship of Bavaria (1623).

Forced by Austria  to enter the war against France, he signed a separate peace in 1801. Dis�  trustful of Austria, he supported the French war effort (1805-09) through  Bavaria�s membership in the Confederation of the Rhine. He received ter�</p><p>ritories by which he crowned himself king of B avaria (1806). After 1813 he  allied with Austria to guarantee the integrity of his kingdom and gave up  sections of western Austria in return for territories on the western bank of  the Rhine. Aided by his chief minister, count von Montgelas (1759-1838),  Maximilian made Bavaria into an efficient, liberal state under a new con�  stitution (1808) and charter (1818) that established a bicameral parliament.</p><p>Maximilian I (b.

He retook  most of the Habsburg lands in Austria from the Hungarians by 1490, and,  after being crowned Holy Roman emperor, he drove the Turks from the  empire�s southeastern borders. He fought a series of wars against the  French, helping to force them out of Italy in 1496 but losing Milan to  them in 1515. He lost Switzerland as well but acquired the Tirol peace�  fully.

He proposed a league of  smaller states as a �third force� in German affairs but was opposed by the  dominant states of Austria and Prussia.

He became king of Bohemia in 1562  and succeeded to the imperial throne in 1564. He extended religious tol�  erance and worked for reform of the Roman Catholic church.

Salinger, Eudora Welty, and Mavis Gallant. He himself was  the author of spare, evocative short stories and novels. Perhaps his best-  known work is The Folded Leaf (1945), about the friendship of two  small-town boys. Among his other works are the novels The Chateau  (1961) and So Long, See You Tomorrow (1980) and the short-story col�  lection All the Days and Nights (1995).</p><p>Maxwell's equations Four equations, formulated by James Clerk  Maxwell, that together form a complete description of the production and  interrelation of electric and magnetic fields. The statements of these four  equations are (1) electric field diverges from electric charge, (2) there are  no isolated magnetic poles, (3) electric fields are produced by changing  magnetic fields, and (4) circulating magnetic fields are produced by  changing electric fields and by electric currents. Maxwell based his  description of electromagnetic fields on these four statements.</p><p>May beetle See June beetle</p><p>May Day In Europe, the day (May 1) for traditional springtime cel�  ebrations. It probably originated in pre-Christian agricultural rituals. Cel�  ebrations included a May king and queen, a Maypole, and people carrying  trees, green branches, or garlands. May Day was designated an interna�  tional labour day by the International Socialist Congress of 1899, and it  remains the standard Labour Day worldwide, with a few exceptions,  including Canada and the U.S. A major holiday in the Soviet Union and  other communist countries, it was the occasion for important political  demonstrations.</p><p>May Fourth Movement Chinese intellectual revolution and socio�  political reform movement (1917-21). In 1915 young intellectuals  inspired by Chen Duxiu began agitating for the reform and strengthening  of Chinese society through acceptance of Western science, democracy,  and schools of thought, one objective being to make China strong enough  to resist Western imperialism. On May 4, 1919, reformist zeal found focus  in a protest by Beijing�s students against the Versailles Peace Confer�  ence�s decision to transfer former German concessions in China to Japan.  After more than a month of demonstrations, strikes, and boycotts of Japa�  nese goods, the government gave way and refused to sign the peace treaty  with Germany. The movement spurred the successful reorganization of  the Nationalist Party and gave birth to the Chinese Communist Party. See  also Treaty of Versailles.</p><p>maya Vml-oX In Hinduism, a powerful force that creates the cosmic illu�  sion that the phenomenal world is real. The word maya originally referred  to the wizardry with which a god can make human beings believe in what  turns out to be an illusion, and its philosophical sense is an extension of  this meaning. The concept is especially important in the Advaita school  of the orthodox system of Vedanta, which sees maya as the cosmic force  that presents the infinite Brahman as the finite phenomenal world.</p><p>Maya \'mI-9\ Group of Mesoamerican Indians who between ad 250 and  900 developed one of the Western Hemisphere�s greatest civilizations. By  ad 200 they had developed cities containing palaces, temples, plazas, and  ball courts. They used stone tools to quarry the immense quantities of  stone needed for those structures; their sculpture and relief carving were  also highly developed. Mayan hieroglyphic writing survives in books and  inscriptions. Mayan mathematics featured positional notation and the use  of the zero; Mayan astronomy used an accurately determined solar year  and precise tables of the positions of Venus and the Moon. Calendrical</p><p>accuracy was important for the elaborate rituals and ceremonies of the  Mayan religion, which was based on a pantheon of gods. Ritual blood�  letting, torture, and human sacrifice were employed in an attempt to pro�  pitiate the gods, ensure fertility, and stave off cosmic chaos. At the height  of its Classic period, Mayan civilization included more than 40 cities of  5,000-50,000 people. After 900 the civilization declined rapidly for  unknown reasons. Descendants of the Maya are now subsistence farmers  in southern Mexico and Guatemala.

They are made of fig-bark paper folded like an accor�  dion, with covers of jaguar skin. Though most Mayan books were  destroyed as pagan by Spanish priests, four are known to have survived:  the Dresden Codex, probably dating from the 11th or 12th century, a copy  of earlier texts of the 5th-9th century; the Madrid Codex, dating from the  15th century; the Paris Codex, slightly older than the Madrid Codex; and  the Grolier Codex, discovered in 1971 and dated to the 13th century. They  deal with astronomical calculations, divination, and ritual.</p><p>Maya languages or Mayan languages Family of about 30  American Indian languages and language complexes, spoken by more  than three million people, mainly in southern Mexico and Guatemala.  While some have few remaining speakers, Yucatec in Mexico and K�iche  (Quiche), Kaqchikel (Cakchiquel), Mam, and Q�eqchi� (Kekchf) in Gua�  temala count speakers in the hundreds of thousands. Maya languages were  recorded in an indigenous script (see Maya Codices; Mayan hieroglyphic  writing), as well as in colonial documents in a Spanish-based orthogra�  phy, including the Popol Vuh and the Yucatec prophetic texts known as the  Books of Chilam Balam.</p><p>Mayakovsky \m3- I y3-'k6f-ske\, Vladimir (Vladimirovich) (b.</p><p>July 19, 1893, Bagdadi, Georgia, Russian Empire�d. April 14, 1930,  Moscow, Russia, U.S.S.R.) Russian poet. Repeatedly jailed for subver�  sive activity, he began writing poetry during solitary confinement in 1909.  On his release he became the spokesman for Futurism in Russia, and his  poetry became conspicuously self-assertive and defiant. He was the lead�  ing poet of the Russian Revolution of 1917 and the early Soviet period,  producing declamatory works saturated with politics and aimed at mass  audiences, including �Ode to Revolution� (1918) and �Left March�  (1919) and the drama Mystery Bouffe (performed 1921). Disappointed in  love, increasingly alienated from Soviet reality, and denied a visa to travel  abroad, he committed suicide at age 36.</p><p>Mayan VmI-on\ hieroglyphic writing System of writing used by  people of the Maya civilization from about the 3rd century ad to the 17th  century. Of the various scripts developed in pre-Columbian Mesoamer-  ica, Mayan writing is by far the most elaborate and abundantly attested:  about 800 signs have been inventoried in more than 5,000 instances (see  Maya Codices). Signs�some representational, some quite abstract�are  either logographic, representing words, or syllabic, representing  consonant-vowel sequences. Typically, up to five signs are fit into tight  square or rectangular clusters, which are further arranged into rows or  grids. The language of Classic Period writing (c. ad 250-900) is gener�  ally thought to be Cholan, ancestral to several modern Maya languages;  later inscriptions were in Yucatec. By the 1990s scholars had an accurate  grasp of 60-70% of Mayan inscriptions, with some texts almost com�  pletely readable and some still quite opaque. Most inscriptions record sig�  nificant events and dates in the lives of Mayan rulers.</p><p>Mayer, Louis B(urt) orig. Eliezer Mayer or Lazar Mayer (b.</p><p>July 4, 1885, Minsk, Russian Empire�d.

He bought a small nickelodeon near Boston in 1907,  and by 1918 he owned the largest chain of movie theatres in New England.  He founded a film production company in Hollywood in 1917 and merged  it with other companies to form MGM in 1925. Under his leadership,  MGM became Hollywood�s largest and most prestigious studio, aided by  his artistic director, Irving Thalberg. Mayer had under contract many of the  outstanding screen stars of the day, including Greta Garbo, Clark Gable,  and Judy Garland. He was considered the most powerful Hollywood  executive until his forced retirement in 1951.

Together with Sam  Gooden (bass) and Fred Cash (low tenor), Mayfield (high tenor) devised  a much imitated vocal style. Mayfield was a self-taught guitarist, and  when he tuned his instrument to a natural chord, he achieved a subtle  lyricism that was also influential. Mayfield�s songs, including �It�s All  Right� (1963), �People Get Ready� (1965), and �Choice of Colors�  (1969), were inspirational and humanistic. The high point of his solo  career (from 1970) was the influential soundtrack to Superfly (1972), and  he became a major force in the development of the musical style known  as funk. He was paralyzed when a lighting tower fell on him during a  concert in 1990.</p><p>mayflower See trailing arbutus</p><p>Mayflower Compact (1620) Document signed by 41 male passen�  gers on the Mayflower before landing at Plymouth (Massachusetts).

The approximately 2,000 species are up to 1.6 in. (4 cm) long,  have triangular membranous forewings, smaller round hind wings, and  two or three long, threadlike tails. Wings are held vertically when at rest.  Chewing mouthparts in the aquatic larvae are vestigial in the adult, which  lives just long enough to mate and reproduce. Males �dance� in large  swarms to attract females. The adult�s entire life span is usually only a  few hours (though at least one species lives as long as two days), and  poets have used the mayfly as a symbol of life�s ephemeral nature.</p><p>mayhem Crime of willfully and permanently crippling, mutilating, or  disfiguring any part of another�s body.

It is popular with climbers and campers and is the  centre of Mayon Volcano National Park, which occupies 21 sq mi (55 sq  km). It has erupted more than 30 times since 1616; an eruption in 1993  killed 75 people. Its most destructive eruption was in 1814, when the town  of Cagsawa was buried.</p><p>mayor Political leader of a municipal corporation. Mayors are either  appointed or elected for a limited term. In Europe until the mid-19th cen�  tury, most mayors were appointed by the central government; in France,  they are still agents of the central government. In the U.S., they are either  directly elected by the populace or chosen by an elected council. Some  fulfill only ceremonial functions, executive power being held by a pro�  fessional manager hired by the legislature. A mayor�s powers may include  the power to make appointments, veto legislation, administer budgets, and  manage administrative functions.

Most of its people are of  Malagasy origin. Originally inhabited by descendants of Bantu and  Malayo-Indonesian peoples, it was converted to Islam by Arab invaders  in the 15th century. Taken by Malagasy people from Madagascar at the  end of the 18th century, it came under French control in 1843. Together  with the other Comoros islands and Madagascar, it became part of a single  French overseas territory in the early 20th century. It has been adminis�  tered separately since 1975, when the three northernmost islands of the  Comoros declared independence.</p><p>maypole Tall wooden pole garlanded with flowers and greenery and  often hung with ribbons that are woven into complex patterns by dancers  in a ceremonial folk dance. The custom probably originated in ancient  fertility rites that involved dancing around a living tree in the springtime.

He worked for French inter�  ests in the papal court, then entered  the service of France and became a  naturalized French citizen (1639)  and a cardinal (1641). After the  deaths of Richelieu (1642) and Louis  XIII (1643), Mazarin was appointed  first minister of France by Anne of  Austria, regent for Louis XIV, and he  directed Louis�s education. A highly  influential adviser to the young king,  he helped train a staff of able administrators. His foreign policy estab�  lished France�s supremacy among the European powers, effecting the  Peace of Westphalia (1648) and the Treaty of the Pyrenees (1659).

Feb. 1, 1941, Washington, D.C.) U.S. public official.  In 1892 he moved to New York, where he organized the Hudson and  Manhattan Railway companies (later consolidated), which built tunnels  under the Hudson River. A prominent supporter of Woodrow Wilson in  the 1912 presidential campaign, he was appointed secretary of the trea�  sury by Wilson in 1913; he married Wilson�s daughter in 1914. During  World War I he directed fund-raising drives that yielded $18 billion for  the war effort. He was later director general of U.S. railroads (1917-19)  and U.S. senator from California (1933-38).</p><p>McCarthy, Cormac orig. Charles McCarthy, Jr. (b. July 20,1933,  Providence, R.I., U.S.) U.S. novelist. He grew up in Tennessee and  dropped out of the University of Tennessee to join the Air Force. He began  writing in 1959. His novels, known for their natural observation, morbid  realism, and violence, are in the Southern gothic tradition. They include  The Orchard Keeper (1965), Outer Dark (1968), Blood Meridian (1985),  and the widely read Border Trilogy (. All the Pretty Little Horses, 1992;  The Crossing, 1994; Cities of the Plain, 1999).</p><p>McCarthy, Eugene J(oseph) (b. March 29, 1916, Watkins, Minn.,  U.S.�d. Dec. 10, 2005, Washington, D.C.) U.S. politician. He taught at  the College of St. Thomas in St. Paul, Minn., before being elected to the  U.S. House of Representatives (1949-59) and later the Senate (1959-71).  A liberal Democrat, he became an outspoken critic of the Vietnam War.  In 1968 he ran for the Democratic Party presidential nomination. His ini�  tial successes convinced Pres. Lyndon B. Johnson not to seek reelection.  After losing the nomination to Hubert H. Humphrey, McCarthy decided not  to run for reelection to the Senate. He made another unsuccessful attempt  at the Democratic nomination in 1972 and ran unsuccessfully for presi�  dent as an independent in 1976. His presidential bids in 1988 and 1992  also failed.</p><p>McCarthy, John (b. Sept. 4, 1927, Boston, Mass., U.S.) U.S. computer  scientist. He received his Ph.D. from Princeton University.

He also devel�</p><p>oped ideas about the processing characteristics of trees (as used in com�  puting), as distinct from nets. He is a recipient of the Turing Award (1971),  the Kyoto Prize (1988), and the National Medal of Science (1990).</p><p>McCarthy, Joseph R(aymond) (b. Nov. 14, 1908, near Appleton,  Wis., U.S.�d. May 2, 1957, Bethesda, Md.) U.S. politician. He was a  Wisconsin circuit judge (1940^42) before enlisting in the Marine Corps  in World War II. In 1946 he upset Robert La Follette, Jr., to win election  to the U.S. Senate. He remained little known until 1950, when he pub�  licly charged that 205 communists had infiltrated the U.S. State Depart�  ment. Reelected in 1952, he obtained the chairmanship of the Senate�s  permanent subcommittee on investigations, and for the next two years he  investigated various government departments and questioned innumerable  witnesses about their suspected communist affiliations. To his supporters,  McCarthy was a dedicated patriot and a guardian of genuine American�  ism; to his detractors, he was an irresponsible witch-hunter who was  undermining the nation�s traditions of civil liberties. The persecution of  innocent persons on the charge of being communists and the forced con�  formity that this practice engendered in American public life came to be  known as McCarthyism. His influence waned after 1954, when exposure  of his truculent interrogative tactics in nationally televised hearings helped  to turn public opinion against him. Later that year he was censured by the  Senate for conduct �contrary to Senate traditions.�</p><p>McCarthy, Mary (Therese) (b. June 21, 1912, Seattle, Wash.,  U.S.�d. Oct. 25, 1989, New York, N.Y.)

Her work is noted for bitingly satiric commentaries on marriage,  the impotence of intellectuals, and the role of women in contemporary  urban America. Her novels include The Company She Keeps (1942); The  Group (1963), her most popular work; Birds of America (1971); and Can�  nibals and Missionaries (1979). She also wrote two autobiographies.

Bom to a working-class family, he learned  piano but switched to guitar after hearing American rock-and-roll record�  ings. In the mid-1950s he met John Lennon, with whom he formed the  Quarrymen, which evolved into the Beatles. He and Lennon cowrote  scores of songs, including some of the most popular songs of the 20th  century. He released his first solo album in 1970. With his wife, the pho�  tographer Linda Eastman (1941-98), he formed the group Wings; their  hit albums include Band on the Run (1973) and Wings at the Speed of  Sound (1976). After the band dissolved, McCartney had a string of hits  in the 1980s. In Rio de Janeiro in 1990, he set a world record by per�  forming before a paying audience of more than 184,000.

MacLeod he provided the first experimental evidence that the genetic  material of living cells is composed of DNA. In their classic experiments  (1944), the introduction of certain material from one type of pneumococ�  cus bacteria into another type transformed the receiving bacteria into the  type from which the material had been taken.

After graduat�  ing from West Point, he served in the Mexican War and then returned to  West Point to teach military engineering. In 1855-56 he undertook a mis�  sion to the Crimea to study European methods of warfare. In 1857 he  resigned his commission to become chief of engineering for the Illinois  Central Railroad (1857); he became president of the Ohio and Mississippi  Railroad in 1860. At the outbreak of the American Civil War he was com�  missioned in the regular army and placed in command of the department  of the Ohio. Appointed general in chief of the army by Abraham Lincoln  in 1861, he organized the army into an efficient fighting force but refused  to take the offensive in the fall of that year, prompting Lincoln to issue  his General War Order (1862) calling for forward movement of all armies.  McClellan cautiously conducted the Peninsular Campaign but failed to  take Richmond, and he fought indecisively in the Seven Days' Battles. At  the Battle of Antietam he failed to destroy Robert E.

U.S. geneticist. She received her doc�  torate from Cornell University. In the 1940s and �50s, her experiments  with variations in the coloration of kernels of com revealed that genetic  information is not stationary. She isolated two control elements in genetic  material and found not only that they moved but that the change in posi�  tion affected the behaviour of neighbouring genes, and she suggested that  these elements were responsible for the diversity in cells during an organ�  ism�s development. Her pioneering research, whose importance was not  recognized for many years, eventually resulted in her being awarded a  1983 Nobel Prize.</p><p>McClung, Clarence E(rwin) (b.

His study of the mechanisms of  heredity led to his hypothesis (1901) that an extra, or accessory, chromo�  some determined sex. The discovery of the sex-determining chromosome  provided some of the earliest evidence that a given chromosome carries  a definable set of hereditary traits. McClung also studied how the behav�  iour of chromosomes in the sex cells of different organisms affects their  heredity.</p><p>McClung, Nellie orig. Nellie Mooney (b.

It was formed in the 1967 merger of  the McDonnell Aircraft Co. (founded 1939) and the Douglas Co. (1921).  During World War II, Douglas contributed 29,000 warplanes, one-sixth of  the U.S. airborne fleet. After the war, it dominated commercial air routes  with its DC-6 and DC-7. With the development of commercial jets, Dou�  glas began to lag behind Boeing Co. and sought a merger with McDon�  nell, which had grown quickly during World War II and had continued to  be a major defense supplier, designing the first carrier-based jet fighter.  After the merger McDonnell Douglas produced widely used jet fighters  (including the F-4 Phantom, A-4 Skyhawk, F-l 5 Eagle, and F-18 Hornet)  as well as launch vehicles and cruise missiles.

His  elementary school series, starting  with The Eclectic First Reader, was  published between 1836 and 1857. Collections of didactic tales, apho�  risms, and excerpts from great books, the readers reflect McGuffey�s view  that the proper education of young people required their introduction to a  wide variety of topics and practical matters. They became standard texts  in nearly all states for the next 50 years and sold more than 125 million  copies. In these years McGuffey also served as president of Cincinnati  College (1836�39) and of Ohio University, Athens (1839^13). He was a  founder of the common school system of Ohio.

His 49 home runs hit during his first season in the  majors set a record, and he was named the American League�s Rookie of  the Year. In 1989 his .343 postseason batting average guided Oakland to  the World Series championship. Injuries plagued him in 1993-95. Traded  to the St. Louis Cardinals in 1997, he hit 58 homers. In 1998 he topped  Roger Maris�s 37-year-old season record of 61 home runs. He and Sammy  Sosa thrilled fans with their home-run competition, and McGwire  achieved the new record with 70; the record was broken in 2001 by Barry  Bonds (73). In 1999 McGwire hit 65 home runs.

Fiore, 1967).</p><p>McMahon Line Frontier between Tibet and Assam in British India,  negotiated between Tibet and Britain at the end of the Shimla (Simla)  Conference in 1913-14. It was named for the chief British negotiator, Sir  Henry McMahon. China refused to recognize the boundary on the grounds  that Tibet, being subordinate to China, could not make treaties. A conflict  in 1962 between India and China failed to resolve the border dispute;  China still considers the boundary illegal.</p><p>McMaster University Privately endowed university in Hamilton,  Ontario, Canada. It was founded in 1887 through a gift from Sen. Wil�  liam McMaster (1811-87). It offers undergraduate and graduate degree  programs in the sciences, humanities, social sciences, business, engineer�  ing, and other fields. Campus resources include a nuclear reactor, educa�  tion research facilities, and the Bertrand Russell Archives.</p><p>McMurdo Sound Bay, western extension of the Ross Sea, Antarctica.  Lying at the edge of the Ross Ice Shelf, the channel is 92 mi (148 km) long  and up to 46 mi (74 km) wide; it has been a major centre for Antarctic  explorations. First discovered in 1841 by Scottish explorer James C. Ross,  it served as one of the main access routes to the Antarctic continent. Ross  Island, on the shores of the sound, was the site of headquarters for Brit�  ish explorers Robert Falcon Scon and Ernest Shackleton.</p><p>McMurtry, Larry (Jeff) (b. June 3, 1936, Wichita Falls, Texas, U.S.)  U.S. novelist. The son of a rancher, he is noted for novels set in the  American West, often in Texas. The Last Picture Show (1966) examines  the isolation of small-town life. Lonesome Dove (1985, Pulitzer Prize) is  part of an epic frontier series that also includes Streets of Laredo (1993),  Dead Man�s Walk (1995), and Comanche Moon (1997). His other novels  include Horseman, Pass By (1961), Terms of Endearment (1975), and  Buffalo Girls (1990). Many of his novels were adapted for film or tele�  vision.</p><p>McNally, Terrence (b. Nov. 3, 1939, St. Petersburg, Fla., U.S.) U.S.  dramatist. He worked as a newspaper reporter, as tutor for the children  of John Steinbeck, and as stage manager at the Actors Studio. His plays,  which often explore relationships and are characterized by dark humour,  include Bad Habits (1971), Master Class (1995), Love! Valour! Compas�  sion! (1995, Tony Award; film, 1997), and the controversial Corpus  Christi (1998, Tony Award). He wrote the book for the musical Kiss of  the Spider Woman (1993).</p><p>McNamara Vmak-no-mar-oV, Robert S(trange) (b. June 9, 1916,  San Francisco, Calif., U.S.) U.S. secretary of defense (1961-68). He  graduated from the University of California at Berkeley (1937), earned a  graduate degree at the Harvard Business School (1939), and later joined  the Harvard faculty. He developed logistical and statistical systems for  the military during World War II. After the war, he was one of the �Whiz  Kids� hired to revitalize the Ford Motor Company, and in 1960 he became  the first president of the company who was not a member of the Ford  family. In 1961 he was appointed secretary of defense by John F. Kennedy.  Though initially a supporter of U.S. involvement in the Vietnam War, by  1967 he advocated peace negotiations; his opposition to the bombing of  North Vietnam caused him to lose influence with Pres. Lyndon B. Johnson.  He resigned in 1968 to become president of the World Bank (1968-81).</p><p>McNeill, Don (b. Dec. 23, 1907, Galena, Ill., U.S.�d. May 7, 1996,  Evanston, Ill.) U.S. radio entertainer. He entered radio in the 1920s as  part of a singing team. In 1933 he took over as host of an NBC morning  program in Chicago and created The Breakfast Club. Usually unscripted,  it relied on listeners� comments, poems, and folksy humour. It was the  longest-running show in radio network history when it ended in 1968.</p><p>McPhee, John (Angus) (b. March 8,1931, Princeton, N.J., U.S.) U.S.  journalist and nonfiction writer. He attended Princeton University. After  working as an associate editor at Time (1957-64), he became a staff writer  at The New Yorker in 1965. His nonfiction covers a wide variety of top�  ics. His first book was on Bill Bradley; places he has written about include  New Jersey, Alaska, the American West (several books), and Switzerland;  other topics include the citrus industry, aeronautical engineering, the  birch-bark canoe, and nuclear terrorism. He has taught journalism at  Princeton since 1975. His later works include Annals of the Former World  (1998, Pulitzer Prize).</p><p>McPherson, Aimee Semple orig. Aimee Elizabeth Kennedy</p><p>(b. Oct. 9, 1890, near Ingersoll, Ont., Can.�d. Sept. 27, 1944, Oakland,  Calif., U.S.) Canadian-born U.S. Pentecostal evangelist. Bom on a farm,  she began preaching at age 17, and in 1908 she went as a missionary to  China with her husband, Robert Semple. After his death she came to the  U.S., where her second marriage, to Harold McPherson, ended in 1918  when she became an itinerant evangelist and healer. She settled in Los  Angeles and founded the International Church of the Foursquare Gospel.  For nearly 20 years she preached to large audiences at her Angelus  Temple; she also built a radio station, wrote books and pamphlets, and  established about 200 missions. In 1926 she disappeared mysteriously for  five weeks; on her reappearance her tale of kidnapping was greeted with  skepticism. A third marriage ended in divorce, and she faced numerous  trials for financial irregularities. She died from an accidental overdose of  sleeping pills.</p><p>McQueen, (Terence) Steve(n) (b. March 24, 1930, Beech Grove,  Ind., U.S.�d. Nov. 7, 1980, Juarez, Mex.) U.S. film actor. He served time  in a reform school and a stint in the U.S. Marines before studying acting  in New York City. He won notice on Broadway in A Hatful of Rain (1955)  and made his screen debut in Somebody up There Likes Me (1956), then  starred in the television series Wanted: Dead or Alive (1958-61). Cool  and stoical, his loner heroes spoke through actions and rarely with words  in films such as The Great Escape (1963), The Sand Pebbles (1966), Bul�  litt (1968), The Thomas Crown Affair (1968), Papillon (1973), and The  Towering Inferno (1974).</p><p>McRae, Carmen (b. April 8, 1920, New York, N.Y., U.S.�d. Nov. 10,  1994, Beverly Hills, Calif.) U.S. singer and pianist. McRae was influ�  enced by Billie Holiday and Sarah Vaughan. She began her career in 1943  singing at Minton�s Playhouse in Harlem, absorbing the innovations of  the first bebop musicians. Working as a soloist from the mid-1950s, McRae  became one of the most accomplished scat singers and ballad interpret�  ers in jazz.</p><p>Me 109 See Messerschmitt 109  Me Nam River See Chao Phraya River</p><p>mead Alcoholic beverage fermented from honey and water. It can be  light or rich, sweet or dry, or even sparkling. Alcoholic drinks made from  honey were common in ancient Scandinavia, Gaul, Teutonic Europe, and  Greece; they were particularly common in northern Europe, where grape�  vines do not flourish. By the 14th century, ale and sweetened wine were  surpassing mead in popularity. Today mead is made as a sweet or dry  wine of low alcoholic strength.

Feb. 27, 1863, South Hadley, Mass.,  U.S.�d. April 26, 1931, Chicago, Ill.) U.S. philosopher, sociologist, and  social psychologist prominent in the development of pragmatism. He stud�  ied at Oberlin College, graduated from Harvard University (B.A., 1888),  and went on to study philosophy and psychology at the Universities of  Leipzig and Berlin (1888-91). Mead then taught philosophy and psychol�  ogy at the University of Michigan (1891-94) with John Dewey and Charles  Horton Cooley. In 1894 he joined Dewey in moving to the University of  Chicago and taught there the rest of his life. Mead�s focus was the rela�  tionship between the self and society, particularly the emergence of the  human self in the process of social interaction. His works include The  Philosophy of the Present (1932) and Mind, Self, and Society (1934). See  also INTERACTIONS.</p><p>Mead, Lake Reservoir of the Hoover Dam, on the Arizona-Nevada bor�  der in the U.S. One of the largest man-made lakes in the world, it was  formed by the damming of the Colorado River. Lake Mead is 115 mi (185  km) long and 1-10 mi (1.6-16 km) wide; it has a capacity of over 31  million acre ft (38 billion cubic m), with a surface area of 229 sq mi (593  sq km). It was named after Elwood Mead, commissioner of reclamation.  Lake Mead National Recreation Area (established 1936) has an area of  2,338 sq mi (6,055 sq km) and extends 240 mi (386 km) along the river.</p><p>Mead, Margaret (b. Dec. 16, 1901, Philadelphia, Pa., U.S.�d. Nov.  15, 1978, New York, N.Y.) U.S. anthropologist. She studied under Franz  Boas and Ruth Benedict at Columbia University and did fieldwork in Samoa  before completing her Ph.D. (1929). The first and most famous of her 23  books, Coming of Age in Samoa (1928), presents evidence in support of  cultural determinism with respect to the formation of personality or tem�  perament. Her other books include Sex and Temperament in Three Primi�  tive Societies (1935), Male and Female (1949), and Culture and  Commitment (1970). Her theories caused later 20th-century anthropolo�  gists to question both the accuracy of her observations and the soundness  of her conclusions. In her later years she became a prominent voice on  such wide-ranging issues as women�s rights and nuclear proliferation, and  her great fame owed as much to the force of her personality and her out�  spokenness as to the quality of her scientific work. She served in cura�  torial positions at the American Museum of Natural History for over 50  years.</p><p>Meade, George G(ordon) (b. Dec. 31, 1815, Cadiz, Spain�d. Nov.  6, 1872, Philadelphia, Pa., U.S.) U.S. general in the American Civil War.  He was the son of a U.S. naval agent in Spain. After graduating from West  Point in 1835, he worked as a surveyor. He reentered the army in 1842 and  in 1861 was commissioned brigadier general in the Pennsylvania volun�  teers. He fought at Bull Run, Antietam, and Chancellorsville. Three days  before the Battle of Gettysburg, he replaced Joseph Hooker as commander  of the Army of the Potomac. At Gettysburg he repulsed the Confederate  attack but was criticized for failing to pursue Robert E. Lee�s forces. From  1864 he was subordinate to Gen. Ulysses S. Grant, whom he served loy�  ally. After the war he commanded several military departments.</p><p>meadowlark Any sharp-billed, plump songbird of the genus Sturnella  (family Icteridae), 8-11 in. (20-28 cm) long. The two North American  species are streaked brown above and have a yellow breast crossed by a  black V; the short tail has distinctive white outer feathers. The eastern, or  common, meadowlark ( S. magna), from eastern Canada to Brazil, has a  simple four-note whistle; the western meadowlark ( S. neglecta ), from  western Canada to Mexico, has an intricate fluting song. Meadowlarks  eat insects in summer and seeds in fall and winter. Their nests are grass  domes hidden in fields.</p><p>mealybug Any insect of the family Pseudococcidae (order  Homoptera). Not a true bug, the mealybug is covered by a white sticky  powder resembling cornmeal. The females, about 0.4 in. (1 cm) long, and  �crawlers� (the active young) cluster along the veins and undersides of  leaves, especially of citrus trees and potted plants; the males are active  two-winged fliers. Common species are the citrus mealybug ( Pseudococ�  cus citri) and the citrophilus mealybug (P gahani).</p><p>mean life In radioactivity, the average lifetime of all the nuclei of a par�  ticular unstable atomic species. This time interval is the sum of the life�  times of all the individual unstable nuclei in a sample, divided by the total  number of unstable nuclei present. It is the reciprocal of the decay con�  stant. For a given isotope, the mean life is always 1.443 times its half-  life. For example, lead-209 decays to bismuth-209 with a half-life of 3.25  hours and a mean life of 4.69 hours.</p><p>mean, median, and mode In mathematics, the three principal ways  of designating the average value of a list of numbers. The arithmetic mean  is found by adding the numbers and dividing the sum by the number of  numbers in the list. This is what is most often meant by an average. The  median is the middle value in a list ordered from smallest to largest. The  mode is the most frequently occurring value on the list. There are other  types of means. A geometric mean is found by multiplying all values in  a list and then taking the root of that product equal to the number of val�  ues (e.g., the square root if there are two numbers). The geometric mean  is typically used in cases of exponential growth or decline (see exponen�  tial function). In statistics, the mean of a random variable is its expected  value�i. e., the theoretical long-run arithmetic mean of the outcomes of  repeated trials, such as a large number of tosses of a die.</p><p>mean-value theorems In mathematics, two theorems, one associ�  ated with differential calculus and one with integral calculus. The first pro�  poses that any differentiable function defined on an interval has a mean  value, at which a tangent line is parallel to the line connecting the end�  points of the function�s graph on that interval. For example, if a car cov�  ers a mile from a dead stop in one minute, it must have been traveling  exactly a mile a minute at some point along that mile. In integral calcu�  lus, the mean value of a function on an interval is, in essence, the arith�  metic mean (see mean, median and mode) of its values over the interval.  Because the number of values is infinite, a true arithmetic mean is not  possible. The theorem shows how to find the mean value using a definite  integral. See also Rolle's theorem.</p><p>meander \me-'an-d9r\ Extreme U-bend in a stream, usually occurring  in a series, that is caused by flow  characteristics of the water. Mean�  ders form in stream-deposited sedi�  ments and may stack up upstream of  an obstruction, resulting in a goose�  neck or extremely bowed meander. A  cutoff may form through the goose�  neck and allow the former meander  bend to be sealed off as an oxbow  lake. Silt deposits may eventually fill  the lake to form a marsh or a mean�  der scar.</p><p>meaning In philosophy and lin�  guistics, the sense of a linguistic  expression, sometimes understood in  contrast to its referent. For example,  the expressions �the morning star�  and �the evening star� have different  meanings, though their referent  (Venus) is the same. Some expres�  sions have meanings but no referents  (�the present king of France�) or ref�  erents but no meanings (�that�). The  literal or conventional meaning of an  expression may differ from what a  speaker of that expression means by uttering it on a particular occasion;  this is the case with similes, statements uttered ironically, and statements  that convey various �conversational implicatures,� as in the following  examples: �She entered the house and shot him� implicates that she shot  him in the house after she entered it, though this is not part of the sen�  tence�s literal meaning; �John has three sons� implicates that John has no  more than three sons, though again the sentence does not literally say this.  Other non-literal aspects of meaning include the potential for carrying out  various �speech acts� (see speech act theory); e.g., uttered in the appropri�  ate circumstances, the sentence �I christen thee the Joseph Stalin ,� con�  stitutes the act of naming a ship, and the sentence �I am cold� constitutes  a request to close the window.

A plumber by trade, he joined  the United Association of Plumbers and Steam Fitters in 1915 and rose  through the ranks as a union official. He was elected secretary-treasurer  of the American Federation of Labor (AFL) in 1939 and became its presi�  dent in 1952. He led the merger of the AFL and the Congress of Indus�  trial Organizations (CIO) in 1955, helping reconcile the two federations  despite their competitiveness and long-standing differences. Conservative  and anticommunist, as president of the AFL-CIO (1955-79) he steered the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>measles &#x25BA; Mecherino I 1225</p><p>U.S. labour movement away from radicalism.

Meany wielded considerable influence in the Democratic Party through  the 1970s.</p><p>measles or rubeola V.ru-be-'o-ls, rii-'be-'o-loX Highly contagious viral  childhood disease. It initially resembles a severe cold with red eyes and  fever; a blotchy rash and higher fever later develop. After recovery,  patients have lifelong immunity. Adult patients tend to have more severe  cases. Antibiotics now prevent death from secondary infections. Measles  itself, for which there is no drug, requires only bed rest, eye protection,  and steam for bronchial irritation. A vaccine developed in the 1960s  proved not to give permanent immunity and is too heat-sensitive for use  in tropical areas. The worldwide incidence of measles continues to rise.  Research is currently directed toward development of a more stable vac�  cine. See also rubella.</p><p>measure theory In mathematics, a generalization of the concepts of  length and area (see length, area, and volume) to arbitrary sets of points  not composed of line segments or rectangles. A measure is any rule for  associating a number with a set. The result must be nonnegative and also  additive, meaning that the measure of two nonoverlapping sets equals the  sum of their individual measures. This is simple enough for sets consist�  ing of line segments or rectangles, but the measure of sets such as curved  regions or intervals with missing points requires more abstract methods,  including limits and upper and lower bounds.</p><p>measurement Association of numbers with physical quantities and  natural phenomena by comparing an unknown quantity with a known  quantity of the same kind. Weights and measures are standard quantities  with which such comparisons are made. The earliest ones measured mass  (weight), volume (liquid or dry measure), length, and area using units  mostly based on dimensions of the human body. The cubit, representing  the distance from elbow to fingertips, was the most widespread unit of  measure in the ancient world. As such units were standardized, more were  added, including units of temperature, luminosity, pressure, and electric  current. Measurements made by the senses instead of by measurement  devices are called estimates (see estimation).</p><p>meat Flesh and other edible parts of animals, particularly mammals, used  for food. Not only the muscles and fat but also organs such as the liver,  kidney, and heart are consumed as meat. Meat is valued as a complete-  protein food, containing all the amino acids necessary for the human body.  It is digested slowly, largely because of the presence of fats. Worldwide,  pork is the most widely consumed meat; beef is second. Mutton and lamb,  goat, venison, and rabbit are other common meats. The U.S. produces and  consumes about a third of the world�s meat, while much of the world�s  population eats little if any meat, though it is generally prized.</p><p>Mecca Arabic Al-Makkah V.al-'ma-koV City (pop., 1992: 965,697),  western Saudi Arabia. The holiest city of Islam, it was the birthplace of  the Prophet Muhammad. It was his home until ad 622, when he was forced  to flee to Medina (see also Hijrah); he returned and captured the city in  630. It came under the control of the Egyptian MamlGk dynasty in 1269  and of the Ottoman Empire in 1517. King Ibn Sa'Od occupied it in 1925,  and it became part of the Kingdom of Saudi Arabia. It is a religious cen�  tre to which Muslims must attempt a pilgrimage (see hajj) once during a  lifetime; only Muslims may enter Mecca. Services related to pilgrimages  are the main economic activity. It is the site of the Haram Mosque, which  contains the Ka'bah.</p><p>mechanical advantage Force-amplifying effectiveness of a simple  machine (lever, wedge, wheel and axle, pulley, or screw). The theoretical  mechanical advantage of a system is the ratio of the force that performs  the useful work to the force applied, assuming there is no friction in the  system. In practice, the actual mechanical advantage will be less than the  theoretical value by an amount determined by the amount of friction.</p><p>mechanical efficiency See efficiency</p><p>mechanical energy Sum of a system�s kinetic energy (KE) and poten�  tial energy (PE). Mechanical energy is constant in a system that experi�  ences no dissipative forces such as friction or air resistance. For example,  a swinging pendulum that experiences only gravitation has greatest KE  and least PE at the lowest point on the path of its swing, where its speed  is greatest and its height least. It has least KE and greatest PE at the  extremities of its swing, where its speed is zero and its height is greatest.</p><p>As it moves, energy is continuously passing back and forth between the  two forms. Neglecting friction and air resistance, the pendulum�s  mechanical energy is constant.</p><p>mechanical engineering Branch of engineering concerned with the  design, manufacture, installation, and operation of engines, machines, and  manufacturing processes. Mechanical engineering involves application of  the principles of dynamics, control, thermodynamics and heat transfer, fluid  MECHANICS, STRENGTH OF MATERIALS, MATERIALS SCIENCE, ELECTRONICS, and MATHEMAT�  ICS. It is concerned with machine tools, motor vehicles, textile machinery,  packaging machines, printing machinery, metalworking machines, weld�  ing, air conditioning, refrigerators, agricultural machinery, and many other  machines and processes essential to an industrial economy.</p><p>mechanical system Any building service using machines. They  include plumbing, elevators, escalators, and heating and air-conditioning  systems. The introduction of mechanization in buildings in the early 20th  century brought about major adjustments; the new equipment demanded  floor space, and the design team began to include electrical and HVAC  (heating, ventilating, and air-conditioning) engineers. Heating and cooling  changed dramatically. Modern buildings, with their large heat gains,  turned central heating into little more than a supplement. Heat removal  is a much more serious burden, especially in warm weather. The roofs of  high-rises are occupied by cooling towers and mechanical penthouses;  entire floors are often dedicated to the containment of blowers, compres�  sors, water chillers, boilers, pumps, and generators.</p><p>mechanics Science of the action of forces on material bodies. It forms  a central part of all physical science and engineering. Beginning with  Newton's laws of motion in the 17th century, the theory has since been  modified and expanded by the theories of quantum mechanics and relativ�  ity. Newton�s theory of mechanics, known as classical mechanics, accu�  rately represented the effects of forces under all conditions known in his  time. It can be divided into statics, the study of equilibrium, and dynamics,  the study of motion caused by forces. Though classical mechanics fails  on the scale of atoms and molecules, it remains the framework for much  of modem science and technology.</p><p>mechanism In mechanical construction, the means of transmitting and  modifying motion in a machine or an assembly of mechanical parts. The  chief characteristic of the mechanism of a machine is that all members  have constrained motion; that is, the parts can move only in certain ways  in relation to each other. Despite its complexity, the mechanism of a  machine can always be analyzed as a group of simple basic mechanisms,  each of which contains members that transmit motion from one moving  link to another. In general, motion is transmitted in one of three ways: by  a wrapping connector such as a chain drive or belt drive, by direct contact  as in a cam or gear, or by a pin-connected linkage.</p><p>mechanism Form of materialism that holds that all natural processes can  be explained in terms of laws of matter in motion. Upholders of mecha�  nism were mainly concerned with eliminating from science all occult  entities, such as substantial form, that could not be empirically observed  or mathematically treated. It thus opposed the use of teleological assump�  tions as explanatory principles in natural science (see teleology). See also  ATOMISM.</p><p>mechanization Use of machines, either wholly or in part, to replace  human or animal labour. Unlike automation, which may not depend at all  on a human operator, mechanization requires human participation to pro�  vide information or instruction. Mechanization began with human-  operated machines to replace the handwork of craftspeople; today  computers are frequently used to control mechanized processes.</p><p>mechanoreception X.me-ko-no-ri-'sep-shonN Ability to detect and  respond to mechanical stimuli in one�s environment. A slight deformation  of a mechanoreceptive neuron causes an electric charge at its surface,  activating a response. Mechanoreceptors in �pain spots� (pressure points)  in the skin (probably clusters of nerve endings) vary in sensitivity. They  respond to a wide range of stimuli, sometimes with a reflex (e.g., a pricked  finger pulled away before the brain registers pain). The structures that  respond to sound (see ear), sense orientation with respect to gravity (see  inner ear), or detect the position and movement of limbs (see propriocep�  tion) are mechanoreceptors. Some animals have mechanoreceptors that  detect water motion or air currents.

Oct. 2, 1987, London, Eng.) Brazilian-born British  zoologist. Educated at Oxford, he began transplant research in 1949. His  finding (1953) that adult animals injected with foreign cells early in life  accept skin grafts from the original donor or its twin lent support to Mac-  farlane Burnet�s hypothesis that cells learn, during and just after birth, to  distinguish �own� from �foreign.� He found that nonidentical cattle twins  accept skin grafts from each other, proving that antigens �leak� between  the embryos� yolk sacs, and showed with mice that each cell contains  genetic antigens important to immunity. His work deflected immunology  from dealing with the fully developed immunity mechanism to attempt�  ing to alter the mechanism itself (e.g., suppression of transplant rejection).  He and Burnet shared a 1960 Nobel Prize.</p><p>Medea Nmo-'de-oX In Greek mythology, the daughter of King Aeetes of  Colchis.

Medicare covers most people 65 or older and those with long-term  disabilities. Part A, a hospital insurance plan, also pays for home health  visits and hospice care. Part B, a supplementary plan, pays for doctors�  services, tests, and other services. Requirements and benefits are com�  plex. Patients pay deductibles and copayments. Medicaid, a joint federal-  state program, covers low-income people under age 65 and those who  have exhausted Medicare benefits. It pays for hospital care, doctors� ser�  vices, nursing-home care, home health services, family planning, and  screening. Participating states must offer Medicaid to all persons on pub�  lic assistance but decide their own eligibility guidelines. Many physicians  refuse to treat Medicaid patients because of low reimbursement levels.</p><p>Medici, Alessandro de' (b. 1510/11, Florence�d. Jan. 5-6, 1537,  Florence) First duke of Florence (1532-37). A member of the elder branch  of the Medici family, he was probably the illegitimate son of Cardinal Giulio  de� Medici (later Pope Clement VII). The pope made Cardinal Passerini  regent in Florence for Alessandro, but they were forced to flee when the  unpopular regency provoked a revolt in 1527. An agreement between the  pope and Emperor Charles V restored the Medici in Florence (1530), and  Alessandro was declared a hereditary duke (1532). A tyrannical ruler, he  sought to solidify his control by marrying Charles V�s daughter, Marga�  ret of Austria, in 1536.

The son of the Flo�  rentine banker Giovanni di Bicci de�Medici (1360-1429), Cosimo repre�  sented the Medici bank and handled papal finances, becoming the  wealthiest man of his time. Another leading family, the Albizzi, had him  imprisoned (1433) and tried to assassinate him, but a year later the Med�  ici regained power in Florence, and Cosimo triumphantly returned. He  was the architect of the Peace of Lodi (1454). An alliance with the Sfor-  zas of Milan provided him with troops to crush a coup d�etat in 1458,  after which he created a Senate composed of 100 loyal supporters (the  Cento). He was a patron of scholarship and the arts, including such fig�  ures as Donatello and Filippo Brunelleschi.</p><p>Medici, Cosimo I de' See Cosimo I</p><p>Medici, Giovanni de' orig. Lodovico (b.

In 1494 his brother, Piero de�  Medici, was ousted as ruler of Florence by the republicans, aided by the  French. In 1512 Pope Julius II demanded that Florence enter his Holy  League against France and allow the exiled Medici to return to Florence.  Giuliano returned as ruler (Piero having died in 1503) and used harsh  measures to suppress a conspiracy. In 1513, after another brother became  Pope Leo X, he went to Rome as a cardinal. In 1515 he received the French  title of duke de Nemours.</p><p>Medici, Lorenzo de' known as Lorenzo the Magnificent (b. Jan.  1, 1449, Florence�d. April 9, 1492,</p><p>Careggi, near Florence) Florentine  statesman and patron of arts and let�  ters. The grandson of Cosimo  de'Medici, he was the most brilliant of  the Medici family. He ruled Florence  with his younger brother, Giuliano,  from 1469. Giuliano was assassi�  nated in 1478 by the Pazzi, a leading  Florentine banking family, which  was in league with Pope Sixtus IV  (who did not support the assassina�  tion) and the king of Naples. Loren�  zo�s direct appeal to the king allowed  him to regain power in Florence, and  he was sole ruler of the city until his  death. His 13-year-old son Giovanni  was created a cardinal by Pope Inno�  cent VIII and later became pope as  Leo X. Lorenzo used the Medici  riches to patronize many artists,  including Sandro Botticelli, Leonardo  da Vinci, and Michelangelo, and he  remains perhaps the most famous patron of all time. His policies bank�  rupted the Medici bank, but the political power of the Medici remained  strong in Florence and Tuscany.</p><p>Medici family Italian bourgeois family that ruled Florence and later  Tuscany from c. 1430 to 1737. The family, noted for its often tyrannical  rulers and its beneficent patrons of the arts, also provided the church with  four popes (Leo X, Clement VII, Pius IV, and Leo XI) and married into the  royal families of Europe, notably in France (Catherine de Medicis and  Marie de Medicis). The effective founder of the family was Giovanni di  Bicci de� Medici (1360-1429), a merchant who amassed great wealth in  trade and was the virtual ruler of Florence from 1421 to 1429. From his  two sons derived the major branches of the family. The so-called elder  branch began with Cosimo de� Medici. His grandson, Lorenzo de� Medici,  or Lorenzo the Magnificent, greatly expanded the family�s power. His son  Giuliano de� Medici became duke de Nemours. Another son, Giovanni,  became Pope Leo X. Lorenzo�s great-granddaughter was Catherine de  Medicis. Another of Cosimo�s grandsons, Giulio de� Medici (1478-1534)  became pope as Clement VII. His probable illegitimate son, Alessandro  de� Medici, a tyrant, was the last of the direct male line of the elder branch.  The so-called younger branch of the family began with Giovanni�s  younger son Lorenzo de� Medici. His son Giovanni married Caterina  Sforza of the powerful Sforza family, and their son Giovanni de� Medici  became a noted general. His son Cosimo I became duke of Florence, and  Cosimo�s son Francesco de� Medici (1541-87) was the father of Marie  de Medicis. Cosimo I�s grandson Cosimo II (1590-1621) gave up the  family practice of banking and commerce. Cosimo II�s grandson Cosimo  III (1642-1723) was a weak ruler, under whom Tuscany�s power declined.  His son Gian Gastone de� Medici (1671-1737), who died without issue,  was the last grand duke of Tuscany.</p><p>medicine Set of scientific fields related to prevention, diagnosis, and  treatment of disease and maintenance of health, practiced in doctors�  offices, health maintenance organization facilities, hospitals, and clinics.

The practice has existed in all religions  since ancient times. In Hinduism it has been systematized in the school  of Yoga. One aspect of Yoga, dhyana (Sanskrit: �concentrated medita�  tion�), gave rise to a school of its own among the Buddhists, becoming  the basis of Zen. In many religions, meditation involves verbal or mental  repetition of a single syllable, word, or text (e.g., a mantra). Visual images  (e.g., a mandala) or mechanical devices such as prayer wheels or rosaries  can be useful in focusing concentration. In the 20th century, movements  such as Transcendental Meditation emerged to teach meditation techniques  outside a religious context.</p><p>Mediterranean fruit fly or Med fly Fruit fly ( Ceratitis capitata)  proven to be particularly destructive to citrus crops, at great economic  cost.

It is a burrowing carnivore found in south�  western Africa that differs from mongooses in having four (rather than  five) toes on each foot. Meerkats are noted for their constant vigilance for  predators. This sentinel behaviour involves one member of the group  finding an elevated position, standing on its hind legs, and alerting the  group of danger when it is seen. The meerkat grows to a total length of  17-24 in. (43-60 cm). Insects and other small animals constitute most of  its diet, but bulbous roots are also eaten for the water they contain. It is  diurnal and easily tamed as a pet. The yellow mongoose ( Cynictis peni-  cillata) is sometimes called the red meerkat.</p><p>meerschaum Vmir-shom, , mir- l shom\ Fibrous hydrated magnesium  silicate that is opaque and white, gray, or cream in colour. Also called  sepiolite, meerschaum (German: �sea foam�) is easily fashioned, and has  been used in jewelry and for tobacco pipes. It is soft when first extracted,  but it hardens on drying. Meerschaum is an alteration product of serpen�  tine.

During the Peloponnesian War (431-404 bc) it was subjugated by  Athens and forced into financial ruin. In the 4th century ad it recovered  some prosperity, but in 1500 it was depopulated by the Venetians. It was the  birthplace of Eucleides, founder of the Megarian school of philosophy.</p><p>Megarian school \me-'gar-e-3n\ or Megarics School of philosophy  founded in Greece in the early 4th century bc by Eucleides of Megara  (died c. 380 bc). It is noted more for its criticism of Aristotle and its influ�  ence on Stoic logic (see Stoicism) than for its doctrines. Among Eucleides�  successors was Eubulides of Miletus, who criticized Aristotle�s doctrines  of categories, movement, and potentiality. Other Megarians were  Diodorus Cronus (fl. 4th century bc) and Stilpo (fl.c. 380-300 bc); Stilpo  taught Zeno of Citium, and Menedemus (339?-c. 265 bc).

In 1713 he joined the Mengyangzhai (imperial bureau created to  synthesize Western and Chinese scientific knowledge) as one of the chief  editors of Liili yuanyuan (c. 1723; �Source of Mathematical Harmonics  and Astronomy�)- Purely a work of Chinese authorship, the Liili yuanyuan  reapportioned credit to Chinese scholars for many discoveries that earlier  Jesuit-Chinese compendiums had credited to Europeans. Studying West�  ern algebra enabled Mei to decipher Chinese mathematical treatises from  the Song (920-1279) and Yuan (1206-1368) dynasties whose methods  had been lost; this led him to expound a theory of the Chinese origin of  Western knowledge. While now acknowledged as grossly overstated,  Mei�s views helped to revive interest in traditional Chinese mathematics  and remained highly influential for many decades.</p><p>Mei Wending (b. 1633, Xuangcheng, Anhui province, China�d. 1721,  China) Chinese writer on astronomy and mathematics whose work rep�  resented an association of Chinese and Western knowledge.

Early in his career he executed a series of spectacular private  residences. These houses typically feature refinements of and variations on  classic Modernist principles�pure geometry, open space, and an emphasis  on light�and they often display a crisp whiteness that contrasts sharply  with the natural setting; the Douglas House, Harbor Springs, Mich. (1973),  is a dramatically sited example. Building upon the success of his resi�  dences, beginning in the mid 1970s Meier began to receive large public  commissions. These structures are characterized by geometric clarity and  order, which is often punctuated by curving ramps and railings, and by a  contrast between the light-filled, transparent surfaces of public spaces and  the solid white surfaces of interior, private spaces. His Getty Center in Los  Angeles (1984-97), with its terraced gardens, is a resplendent acropolis in  travertine stone.

After the Meiji Restoration (1868), Japan�s leaders sought to create a con�  stitution that would define Japan as a capable, modern nation deserving  of Western respect while preserving their own power. The resultant docu�  ment called for a bicameral parliament (the Diet) with an elected lower</p><p>house and a prime minister and cabinet appointed by the emperor. The  emperor was granted supreme control of the army and navy. A privy  council composed of the Meiji leaders (see genro), created prior to the  constitution, advised the emperor and wielded actual power. Voting  restrictions, which limited the electorate to about 5% of the adult male  population, were loosened over the next 25 years, resulting in universal  male suffrage. Political parties made the most of their limited power in  the 1920s, but in the 1930s the military was able to exert control without  violating the constitution. After World War II, a U.S.-approved constitu�  tion stating that �sovereign power resides with the people� replaced the  Meiji Constitution. See also Ito Hirobumi.</p><p>Meiji emperor orig. Mutsuhito (b. Nov. 3, 1852, Kyoto, Japan�d.  July 30, 1912, Tokyo) Emperor of Japan during whose reign (1867-1912)  the Tokugawa shogunate was overthrown, Japan was transformed into a  world power, and the imperial throne came to the forefront of the politi�  cal scene after centuries of being overshadowed by shogunal rule. He  believed in the need to modernize Japan along Western lines. Under the  Meiji emperor the domains (ban) and old class system were abolished, a  new school system was introduced, and the Meiji Constitution was pro�  mulgated. Also during his reign Taiwan was annexed after the SlNO-  Japanese War (1894-95), Korea was annexed (1910), and Japan defeated  Russia in the Russo-Japanese War (1904-05). See also Tokugawa period;  Meiji period; Meiji Restoration.</p><p>Meiji period (1868-1912) Period in Japanese history beginning with  the enthronment of the Meiji emperor and ending with his death. It was a  time of rapid modernization and westernization. Feudal domains were  abolished and replaced with prefectures; daimyo and samurai were relieved  of their special privileges. Not all samurai were happy with the changes,  and there were numerous rebellions, notably that of Saigo Takamori. To  secure a strong central government, a national army was formed and uni�  versal conscription was enacted. A new agricultural tax was instituted to  finance the new government, and a decimal currency was introduced.  Eager to encourage economic growth, the government aided the textile  industry, established railways and shipping lines, and founded an iron�  works. Education was also reformed, and compulsory coeducational  elementary schools were introduced. By 1912 the goals of the reforming  movement called the Meiji Restoration had been largely accomplished: the  unequal treaties with Western powers had been revised, the country was  developing well economically, and its military power had won the respect  of the West. See also Charter Oath; Meiji Constitution.</p><p>Meiji Restoration Overthrow of Japan�s Tokugawa shogunate (see  Tokugawa period) and restoration of direct imperial rule (through the Meiji  emperor) in 1868. In the 19th century the shogunate�s policy of isolation  was challenged by Russia, England, and the U.S., making Japanese feu�  dal leaders aware of Japan�s vulnerability to superior Western firepower.  After the visit of Commodore Matthew Perry, the country was forced to  sign a series of unequal treaties, which, as in China, gave Western nations  special privileges in Japan. In response, young samurai from feudal  domains historically hostile to the Tokugawa regime took up arms against  the government. In January 1868 they announced the restoration of the  emperor to power, and in May 1869 the last Tokugawa forces surrendered.  The revolutionaries had the emperor issue the Charter Oath, which prom�  ised a break with the feudal class restrictions of the past and a search for  knowledge that could transform Japan into a �rich country with a strong  military.� The restoration ushered in the Meiji period, a time of rapid mod�  ernization and Westernization.

He argued that any attempt to  account for linguistic change must recognize that language is a social phe�  nomenon. His Introduction to the Comparative Study of the Indo-European  Languages (1903) explained the relationships of the Indo-European lan�  guages to each other and to their parent tongue. Meillet suggested that lan�  guages that develop farther from a centre of common origin are less  disturbed by changes at the point of origin and more likely to retain archaic  characteristics. He produced authoritative grammars of classical Armenian  and Old Iranian and made notable contributions to Slavic studies.</p><p>Meinhof \ , mIn- l hof\ / Carl (b.

Like his teacher Franz Brentano, Meinong considered intentionality, or  object-directedness, to be the basic feature of mental states. He maintained  that objects of thought have a kind of character or nature ( Sosein ; some�  times rendered �subsistence�) that is distinct from being, or existence  (Sein), which they may lack; thus the golden mountain or the round square  �subsist� as objects of thought, though they do not exist in the world of  sense experience. Meinong�s view briefly influenced Bertrand Russell. His  major writings include On Possibility and Probability (1915) and On  Emotional Presentation (1917).</p><p>meiosis \mI-'o-s3s\ or reduction division Division of a gamete-  producing cell in which the nucleus splits twice, resulting in four sex cells  (gametes, or eggs and sperm), each possessing half the number of chro�  mosomes of the original cell. Meiosis is characteristic of organisms that  reproduce sexually and have a diploid set of nuclear chromosomes (see  ploidy). Before meiosis, chromosomes replicate and consist of joined sis�  ter strands (chromatids). Meiosis begins as homologous paternal and  maternal chromosomes line up along the midline of the cell. The chro�  mosomes exchange genetic material by the process of crossing-over (see  linkage group), in which chromatid strands from homologous pairs  entangle and exchange segments to produce chromatids containing  genetic material from both parents. The pairs then separate and are pulled  to opposite ends of the cell, which then pinches in half to form two  daughter cells, each containing a haploid set (half the usual number) of  double-stranded chromosomes. In the second round of meiotic division,  the double-stranded chromosomes of each daughter cell are pulled apart,  resulting in four haploid gametes. When two gametes unite during fer�  tilization, each contributes its haploid set of chromosomes to the new  individual, restoring the diploid number.

At a laboratory that she set up with Otto  Hahn, the two isolated the radioactive isotope protactinium-231. In the  1930s, with Hahn and Fritz Strassmann (1902-80), she investigated the  products of neutron bombardment of uranium. She left Germany in 1938  for Sweden. After Hahn and Strassmann demonstrated that barium  appears in neutron-bombarded uranium, she and her nephew Otto Frisch  (1904-79) explained the physical characteristics of this division and in  1939 proposed the term fission for the process. She shared the 1966 Enrico  Fermi Award with Hahn and Strassmann. Element 109, meitnerium, is  named in her honour.</p><p>Mekhilta Vmo-'kil-tsX Hebrew commentary on the Book of Exodus.

In 1841 he sailed on a whaler bound for the South Seas; the next  year he jumped ship in the Marquesas Islands. His adventures in Polyne�  sia were the basis of his successful first novels, Typee (1846) and Omoo  (1847). After his allegorical fantasy Mardi (1849) failed, he quickly wrote  Redburn (1849) and White-Jacket (1850), about the rough life of sailors.  Moby-Dick (1851), his masterpiece, is both an intense whaling narrative  and a symbolic examination of the problems and possibilities of Ameri�  can democracy; it brought him neither acclaim nor reward when pub�  lished. Increasingly reclusive and despairing, he wrote Pierre (1852),  which, intended as a piece of domestic �ladies� fiction, became a parody  of that popular genre, Israel Potter (1855), The Confidence-Man (1857),  and magazine stories, including �Bartleby the Scrivener� (1853) and  �Benito Cereno� (1855). After 1857 he wrote verse. In 1866 a customs-  inspector position finally brought him a secure income. He returned to  prose for his last work, the novel Billy Budd, Foretopman, which remained  unpublished until 1924. Neglected for much of his career, Melville came  to be regarded by modern critics as one of the greatest American writers.</p><p>Melville Island One of the largest of the Parry Islands, in the Arctic  Ocean, Canada. Located north of Victoria Island, it is 200 mi (320 km)  long and 30-130 mi (50-210 km) wide, with an area of 16,274 sq mi  (42,149 sq km). It has no human inhabitants, but it supports MUSK OXEN  and has natural-gas deposits. It was discovered in 1819 by William Parry.</p><p>Melville Island Island in the Timor Sea, off the coast of Northern Ter�  ritory, Australia. It is 80 miles (130 km) long and 55 mi (88 km) wide,  with an area of 2,240 sq mi (5,800 sq km). It was sighted by the Dutch  in 1644; the British built Fort Dundas there in 1824. Melville Island,  known to Aboriginals as Yermalner, is one of the few areas in Australia  still occupied by its original Aboriginal peoples, the Tiwi, and in 1978  ownership of the island passed from the Australian government to the Tiwi  Land Council.</p><p>Melville Sound See Viscount Melville Sound</p><p>membrane In biology, the thin layer that forms the outer boundary of  a living cell or of an internal cell compartment. The outer boundary is the  plasma membrane, and the compartments enclosed by internal membranes  are called organelles. Biological membranes have a dual function: sepa�  ration of vital but incompatible metabolic processes conducted in the  organelles; and passage of nutrients, wastes, and metabolic products  between organelles and between the cell and the outside environment.  Membranes consist largely of a double layer of lipids in which are embed�  ded large proteins, many of which transport ions and water-soluble mol�  ecules across the membrane.

Located on the  Baltic Sea north of the Memel River, the area was mainly inhabited by  Lithuanians. In 1919 at the Paris Peace Conference, the newly formed state  of Lithuania requested annexation of the area. A commission recom�  mended formation of a free state, but Lithuanian inhabitants of the region  took over the government in 1923. Protests by the Allied Powers resulted  in the signing of the Memel Statute to establish Memelland as an autono�  mous region within Lithuania.</p><p>Memling Vmem-liq\, Hans or Hans Memlinc Vmem-liqk\ (b. c.  1430/35, Seligenstadt, near Frank�  furt am Main�d. Aug. 11, 1494,</p><p>Bruges) Flemish painter. He settled  in Bruges in 1465 and established a  large workshop that became very  successful and made him one of the  city�s wealthiest citizens. Though  somewhat derivative of the works of  contemporary Flemish painters (Jan  van Eyck, Dirck Bouts, Hugo van der  Goes, and particularly Rogier van der  Weyden), his art has great charm and  a distinctive character. Memling�s  religious paintings and portraits of  wealthy patrons (e.g., Tommaso Por-  tinari and His Wife, c. 1468) were,  and remain, enormously popular.</p><p>Memminger Vme-mon-jorV  Christopher G(ustavus) (b.</p><p>Jan. 9, 1803, Nayhingen, Wiirttem-  berg�d.

After  South Carolina seceded from the Union (1860), he helped draft the pro�  visional constitution of the Confederacy and was appointed its secretary  of the treasury (1861-64). To raise money, he issued increasing amounts  of paper currency, which depreciated greatly by 1863. Held responsible  for the collapse of Confederate credit, he resigned in 1864. After receiv�  ing a presidential pardon, he returned to the practice of law.</p><p>Memnon In Greek mythology, a king of the Ethiopians. The son of  Tithonus (of the Trojan royal house) and Eos (Dawn), he fought bravely  for his uncle Priam against the Greeks, and was slain by Achilles. Moved  by the tears of Eos, Zeus granted him immortality. His companions,  changed into birds, came every year to fight and lament over his grave.  In Egypt his name was connected with the colossal stone statues of Amen-  hotep III near Thebes; the harplike sounds these statues emitted when  touched by the rays of the rising sun were believed to be the voice of  Memnon responding to the greeting of his mother, Eos.</p><p>memoir History or record composed from personal observation and  experience. Closely related to autobiography, a memoir differs chiefly in  the degree of emphasis on external events. Unlike writers of autobiogra�  phy, who are concerned primarily with themselves as subject matter, writ�  ers of memoir usually have played roles in, or have closely observed,  historical events, and their main purpose is describing or interpreting those  events.</p><p>Memorial Day or Decoration Day U.S. holiday. Originally held  (1868) in commemoration of soldiers killed in the American Civil War, its  observance later extended to all U.S. war dead. Most states conform to  the federal practice of observing it on the last Monday in May, but some  retain the traditional day of celebration, May 30. National observance is  marked by the placing of a wreath on the Tomb of the Unknowns in  Arlington National Cemetery. Flags, insignia, and flowers are placed on  the graves of veterans in local cemeteries.</p><p>Memorial University of Newfoundland Canadian public uni�  versity in St. John�s, founded in 1925.

Cam�  pus facilities include centres for research in ocean resources, maritime  history, and political economy.</p><p>memory In digital computers, a physical device used to store such infor�  mation as data or programs on a temporary or permanent basis. Most  digital computer systems have two types of memory, the main memory  and one or more auxiliary storage units. In most cases, the main memory  is a high-speed RAM. Auxiliary storage units include hard disks, floppy  disks, and magnetic tape drives. Besides main and auxiliary memories,  other forms of memory include ROM and optical storage media such as  videodiscs and compact discs (see CD-ROM).</p><p>memory Power or process of recalling or reproducing what has been  learned or experienced. Research indicates that the ability to retain infor�  mation is fairly uniform among normal individuals; what differs is the  degree to which persons learn or take account of something to begin with  and the kind and amount of detail that is retained. Attention, motivation,  and especially association facilitate this process. Visual images are gen�  erally better remembered than are other forms of sense-data. Memory  prodigies, or people with �photographic� or �eidetic� memories, often  draw heavily on visual associations, including mnemonics. Many psy�  chologists distinguish between short- and long-term memory. The former  (variously said to last 10 seconds to 3 minutes) is less subject to inter�  ference and distortion than the latter. Long-term memory is sometimes  divided into episodic (i.e., event-centred) and semantic (i.e., knowledge-  centred) memory. Various models of memory have been proposed, from  the Enlightenment notion of impressions made on brain tissues (restyled  as �memory molecules� or coded �engrams� in the 20th century) to B.F.  Skinner�s �black box� to more recent ideas concerning information pro�  cessing or the formation of neuronal groups. Disorders of or involving  memory include Alzheimer disease, amnesia, Korsakoff syndrome, post-  traumatic stress disorder, and senile dementia.

Founded c. 2925 bc by Menes, it was by the 3rd dynasty a flour�  ishing community. Despite the rivalry of Heracleopolis and Thebes, it  remained important, particularly in the worship of Ptah. Beginning in the  8th century bc, it fell successively to Nubia, Assyria, Persia, and Mace�  donia under Alexander the Great. Its importance as a religious centre was  undermined by the rise of Christianity and then of Islam. It was aban�  doned after the Muslim conquest of Egypt in ad 640. Its ruins include the  great temple of Ptah, royal palaces, and an extensive necropolis. Nearby  are the pyramids of Saqqara and those at Giza.</p><p>Memphis City (pop., 2000: 650,100), southwestern Tennessee, U.S.  Situated above the Mississippi River where the borders of Arkansas, Mis�  sissippi, and Tennessee meet, it was founded in 1819 on the site of a  Chickasaw Indian village and a U.S. fort. It was incorporated as a city in  1826. A Confederate military centre at the start of the American Civil War,  it was captured by Union forces in 1862. In the 1870s yellow fever killed  more than 5,000 residents, and the city was forced into bankruptcy.  Rechartered in 1893, it was the state�s largest city by 1900. Sites of inter�  est include Beale Street, made famous by W.C. Handy as the birthplace  of the blues; and Graceland, the mansion of Elvis Presley. It is the seat of  several educational institutions, including the University of Memphis.</p><p>Memphremagog V.mem-fri-'ma-.gagV Lake Lake that crosses the  U.S.-Canadian border.

He produced his first play in 321 bc, and in 316 he won a festival prize with  Dyscolus (�The Misanthrope�), the only one of his plays for which a com�  plete text still exists. By the end of his career he had written more than 100  plays and had won eight victories at Athenian dramatic festivals. Menander  was considered by ancient critics the supreme poet of Greek New Comedy.  He excelled at presenting characters such as stem fathers, young lovers,  and intriguing slaves. As adapted by the Romans Plautus and Terence, his  plays influenced the later development of Renaissance comedy.</p><p>"Diptych with Madonna and Martin  van Nieuwenhove" (left wing), oil on  panel by Hans Memling, 1487; in the  Memling-Museum, Brugge, Bel.</p><p>COURTESY OF THE MEMLING-MUSEUM, BRUGGE, BEL.,  PHOTOGRAPH, � A.C.L, BRUSSELS</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1234 I Mencius &#x25BA; Mendenhall Glacier</p><p>L_</p><p>N</p><p>Mencius \'men-she-3s\ Chinese Mengzi or Meng-tzu \'m9q-'ts3\  orig.

Mencken  worked on the staff of the Baltimore  Sun for much of his life. With  George Jean Nathan (1882-1958),  he coedited The Smart Set (1914-23)  and cofounded and edited (1924-33)  the American Mercury , both impor�  tant literary magazines. Probably the  most influential U.S. literary critic in  the 1920s, he often used criticism to  jeer at the nation�s social and cultural  weaknesses. Prejudices (1919-27)  collects many of his reviews and  essays. In The American Language  (1919; supplements 1945, 1948) he  brought together American expres�  sions and idioms; by the time of his  death he was perhaps the leading authority on the language of the U.S.</p><p>Mendel Vmen-dalV Gregor (Johann) (b. July 22, 1822, Heinzen-  dorf, Austria�d. Jan. 6, 1884, Briinn, Austria-Hungary) Austrian botanist  and plant experimenter. He became an Augustinian monk in 1843 and later  studied at the University of Vienna. In 1856, working in his monastery�s  garden, he began the experiments that led to his formulation of the basic  principle of heredity. He crossed varieties of the garden pea that had  maintained constant differences in such single alternative traits as tallness  and dwarfishness, flower colour, and pod form. He theorized that the  occurrence of the visible alternative traits of the plants, in the constant  varieties and in their descendants, was due to the occurrence of paired  elementary units of heredity, now known as genes. What was new in  Mendel�s interpretation of his data was his recognition that genes obey  simple statistical laws. His system proved to be of general application and  is one of the basic principles of biology. He achieved fame only after his  death, through the work of Carl Erich Correns, Erich Tschermak von Sey-  senegg, and Hugo de Vries, who independently obtained similar results and  found that both the experimental data and the general theory had been  published 34 years previously.</p><p>Mendele Moykher Sforim Vmen-ds-lo-mo-'ker-sfa-'remX or Men-  dele Mokher Sefarim X.sef-o-'renA orig.

He  lived much of his life in Ukraine, becoming a rabbi and head of a tradi�  tional school (Talmud Torah) at Odessa. His stories, written with lively  humour and gentle satire, are invaluable in the study of Jewish life in  Eastern Europe at the time when its traditional structure was giving way.  His greatest work is The Travels and Adventures of Benjamin the Third  (1875), a panorama of Jewish life in Russia. He is considered the founder  of both modem Yiddish and modern Hebrew narrative literature and the  creator of modem literary Yiddish.</p><p>Mendeleyev X.men-da-'la-ofV, Dmitry (Ivanovich) Mendeleyev</p><p>also spelled Mendeleev (b.

He taught at the Univer�  sity of St. Petersburg (1867-90) and later served as director of Russia�s  bureau of weights and measures. He made a fundamental contribution to  chemistry by establishing in 1869 the principle of periodicity of the ele�  ments. His first periodic table was based on arranging the elements in  ascending order of atomic weight and grouping them by similarity of prop�  erties. Mendeleyev�s theory allowed him to predict the existence and  atomic weights of several elements not discovered until years later.</p><p>Mendelsohn Vmen-dols-.zonV Erich (b. March 21, 1887, Allenstein,  Ger.�d. Sept. 15, 1953, San Francisco, Calif., U.S.) German architect.  While studying architecture in Munich, he was influenced by the Blaue  Reiter group of Expressionist artists. Mendelsohn�s Einstein Tower, Pots�  dam (1919-21), a highly sculptural structure, reflects his early preoccupa�  tion with science fiction. In the 1920s he designed a number of imaginative  structures, including the Schocken stores in Stuttgart (1927) and Chemnitz  (1928), notable for their prominent use of glass in strongly horizontal com�  positions. He fled the Nazis in 1933 and eventually settled in the U.S.; his  American works include the Maimonides Hospital, San Francisco (1946).</p><p>Mendelssohn (-Bartholdy), (Jakob Ludwig) Felix (b. Feb. 3,  1809, Hamburg�d. Nov. 4, 1847, Leipzig) German composer. Grandson  of the philosopher Moses Mendelssohn, he grew up in a wealthy Jewish  family that had converted to Protestantism. He began to compose at age 11;  at 16 he wrote his first masterpiece, the String Octet in E Flat Major (1825),  followed by the Overture to A Midsummer Night�s Dream (1826). In 1829  he conducted the first performance in 100 years of Johann Sebastian Bach�s  St. Matthew Passion, greatly contributing to the Bach revival. He wrote the  first of a series of elegant piano works, Songs Without Words, in 1830. His  Reformation (1832) and Italian (1833) symphonies date from this period.  He observed Classical models and practices while initiating key aspects of  Romanticism, which exalted emotions and the imagination above rigid  forms and traditions. After serving as music director of the Catholic city of  Dusseldorf (1833-35), he took the parallel position in Protestant Leipzig.  There he built up the Gewandhaus Orchestra, making Leipzig the musical  capital of Germany. In his last decade he produced great works such as the  Scottish Symphony ( 1842), the violin concerto (1844), and the oratorio Eli�  jah (1846). His beloved sister, Fanny Mendelssohn Hensel (1805-47), had  been considered his equal in musical talent as a girl, but she was discour�  aged from composing until her marriage to the painter Wilhelm Hensel  (1794-1861); she eventually wrote more than 500 works. Her death was a  severe shock to Mendelssohn; years of overwork simultaneously caught up  with him, and he died six months after her.</p><p>Mendelssohn, Moses orig. Moses ben Menachem (b. Sept. 26,  1729, Dessau, Anhalt�d. Jan. 4, 1786, Berlin, Prussia) German Jewish  philosopher and scholar. The son of an impoverished scribe, he began his  career as a tutor but eventually won fame for his philosophical writings,  which would become influential among the 19th-century U.S. Transcen-  dentalists. He combined Judaism with the rationalism of the Enlighten�  ment, becoming one of the principal figures in the Haskala, which helped  bring Jews into the mainstream of European culture. His works include  Phadon (1767), a defense of the immortality of the soul, and Jerusalem  (1783), on the relationship of religion and the state. His friend Gotthold  Lessing based the protagonist of his celebrated drama Nathan the Wise on  Mendelssohn. He was the grandfather of the composer Felix Mendelssohn.</p><p>Mendenhall Glacier Blue ice sheet, 12 mi (19 km) long, 1.5 mi (2.4  km) wide, and more than 100 ft (30 m) high.

In World War II he was imprisoned by  the Vichy government but escaped to London, where he joined the Free  French air force and served in finance posts in Charles de Gaulle�s pro�  visional government. As a legislator in postwar France (1946-58), he  criticized government policies on economics and the wars in Indochina  and North Africa. In 1954 he became premier; he ended France�s involve�  ment in Indochina and also helped effect autonomy for Tunisia. His pro�  posed economic reforms led to his defeat in 1955. He sought without  success to make the Radical-Socialist Party the centre of the noncommu�  nist left and opposed de Gaulle�s presidency.</p><p>Menelaus \,me-n9-'la-9s\ In Greek mythology, the king of Sparta and  the younger son of Atreus.

At the war�s end he recovered Helen and brought her back to Sparta  instead of killing her as he had intended. Having forgotten to appease the  gods of defeated Troy, he endured a hard voyage home, and many of his  ships were lost.</p><p>Menem Vme-nem\, Carlos (Saul) (b. July 2, 1930, Anillaco, Arg.)  President of Argentina (1989-99). The son of Syrian immigrants, he con�  verted to Roman Catholicism and joined the Peronist movement in 1956.  He held typical Peronist views, favouring nationalism, expansion of the  government, large raises for wage earners, and tax breaks for businesses.  By the time he took office, however, inflation had risen to 28,000% and  Argentina was in crisis; he consequently abandoned his party orthodoxy  in favour of a fiscally conservative policy and succeeded in stabilizing the  economy. A flamboyant figure, he enjoyed great popularity despite his  controversial pardoning of convicted human-rights violators connected  with the period of military rule. In 2001 Menem was placed under house  arrest after he was indicted for illegal arms dealing, but he was released  in 2002.</p><p>Menendez de Aviles Xmo-'nen-dos-da-.a-vo-'lasV Pedro (b.

He was sent to Florida to establish a colony and remove a potential  threat to Spain�s American possessions posed by a French settlement on  the St. Johns River. In 1565 he entered the bay of St. Augustine, where  he built a fort. He attacked the French colony at Fort Caroline and mas�  sacred its entire population, calling its members heretics.

Back in Rome in the late 1740s and again in the early  1750s, he developed an enthusiasm for Classical antiquity. His fresco  Parnassus (1760-61) at the Villa Albani helped establish the ascendancy  of Neoclassical painting. He also worked extensively for the Spanish court  in Madrid.

Menhaden have a deep body,  sharp-edged belly, large head, and tooth-edged scales. Adults are about 15  in. (38 cm) long and weigh 1 lb (0.5 kg) or less. Dense schools of menhaden  range from Canada to South America. When feeding, they swim with  mouth agape and gill openings widespread to strain out plankton.</p><p>menhir Vmen-.hirX Type of ancient megalithic stone monument (see  megalith). Menhirs were simple upright stones, sometimes of great size,  erected chiefly in Western Europe. Arrangements of menhirs often form  vast circles, semicircles, or ellipses. Many were built in Britain, the best-  known sites being Stonehenge and Avebury in Wiltshire. Menhirs were  also placed in parallel rows, called alignments, the most famous being the  Carnac alignments in northwestern France, with 2,935 menhirs. These  were probably used for ritual processions.</p><p>Menilek II Vmen-9-,lek\ orig. Sahle Miriam (b. Aug. 17, 1844,  Ankober, Shewa, Eth.�d.

Captured and  imprisoned for 10 years after his  father, King Malakot of Shewa, was  deposed by Tewodros II. he escaped  in 1865 and returned to Shewa to  assume the title of negus (king). On  the death of Emperor Yohannes IV (r.</p><p>1872-89), he ascended to the Ethio�  pian throne, taking his crown name  from Menilek I, legendary son of  Solomon and the queen of Sheba.</p><p>When Italy sought to make Ethiopia  a protectorate, Menilek roundly  defeated its forces at the Battle of  Adwa (1896).

The pia mater,  a very thin membrane, adheres to the surface of the brain and spinal cord.  The subarachnoid space, containing cerebrospinal fluid, separates the pia  mater from a second membrane, the arachnoid. Around the brain, fine  filaments connect these two membranes, which are believed to be imper�  meable to fluid. The third membrane, the dura mater, is strong, thick, and  dense. It envelops the arachnoid, covers the inside of the skull, and sur�  rounds and supports the large venous channels carrying blood from the  brain. Several septa divide it and support different parts of the brain. In  the spine, the dura mater and the arachnoid mater are separated by the  subdural space; the arachnoid and pia mater are separated by the sub�  arachnoid space. The extradural space (between the dura mater and the  wall of the vertebral canal) is the site of epidural anesthesia (see anesthe�  siology).</p><p>meningitis N.me-non-'jl-tosV Inflammation of the meninges. Bacteria  (including meningococcus, among others), often from infection elsewhere,  produce the most dangerous forms. Symptoms develop rapidly: vomiting,  then severe bursting headache, then stiff neck. Young children may have  convulsions. The patient may die within hours. Pus in cerebrospinal fluid  can block brain passages and spinal spaces, leading to life-threatening  hydrocephalus. Speedy diagnosis (by lumbar puncture) and treatment (with  antibiotics) can prevent brain damage and death. Viral meningitis usually  has a short course and requires no therapy.</p><p>meningococcus Xmo-.niq-go-'ka-kosV Neisseria meningitidis, the bac�  terium that causes meningococcal meningitis in humans, the only natural  hosts in which it causes disease. Meningococci are spherical, frequently  occur in pairs, and are strongly gram-negative (see gram stain). They enter  the nasal passage and may cause no symptoms (up to 30% of the popu�  lation may harbour them between epidemics), or they may enter the blood�  stream and produce the symptoms of meningitis.</p><p>Menninger Vmen-irj-oiA family U.S. physicians and pioneers in psy�  chiatric treatment. Charles Frederick Menninger (1862-1953) was bom  in Tell City, Ind., and began practicing medicine in Topeka, Kan., in 1889.  He saw the benefit of group medical practice after visiting the Mayo fami�  ly�s clinic in 1908. His son Karl (1893-1990) was bom in Topeka and  received psychiatric training in Boston. In 1919 the two founded the  Menninger Diagnostic Clinic for the practice of general medicine and  psychiatry. With Charles�s youngest son, William (1899-1966), they  established the Menninger Sanitarium and Psychopathic Hospital (1925).  Their belief that the mentally ill should be treated, not merely institution�  alized, attracted attention and other scientists, and they made significant  strides in establishing psychiatry as a legitimate science. In 1931 the sani�  tarium became the first training facility for nurses specializing in psychi�  atric care, and in 1933 it opened a neuropsychiatric residency program for  physicians. They formed the Menninger Foundation in 1941 and the Men�  ninger School of Psychiatry in  Topeka four years later.</p><p>Menno Simonsz. Vsl-monz,</p><p>'se-mons\ or Menno Simons (b.</p><p>1496, Witmarsum, Friesland�d.</p><p>Jan. 31, 1561, near Liibeck, Hol�  stein) Dutch Anabaptist leader. Born  into a peasant family, he was  ordained a Roman Catholic priest,  but, doubting the doctrine of transub-  stantiation, he came under the influ�  ence of Lutheranism and withdrew  from the church in 1536. Convinced  that infant baptism was wrong and  that only people of mature faith were  eligible for membership in the  church, he became a leader in the  peaceful wing of the Anabaptist  movement in 1537. Pronounced a  heretic, he was in constant danger of</p><p>arrest for the rest of his life but continued to organize Anabaptist groups.  He wrote and printed many theological works, and his followers founded  the Mennonite Church.</p><p>Mennonite Vme-no-.nflA Member of a Protestant church named for  Menno Simonsz. They trace their origins to the Swiss Brethren (established  1525), nonconformists who rejected infant baptism and stressed the sepa�  ration of church and state. Persecution scattered them across Europe; they  found political freedom first in the Netherlands and northern Poland, and  from there moved to Ukraine and Russia. They first emigrated to North  America in 1663. Many Russian Mennonites emigrated to the U.S. Mid�  west and to Canada in the 1870s when they lost their exemption from  Russian military service. Today Mennonites are found in many parts of  the world, especially in North and South America. Their creed stresses  the authority of the Scriptures, the example of the early church, and bap�  tism as a confession of faith. They value simplicity of life, and many  refuse to swear oaths or serve in the military. The various Mennonite  groups include the strictly observant Amish and Hutterites as well as the  more moderate Mennonite church.</p><p>Menominee Vmo-'na-mo-.neV North American Indian people who live  mostly in northeastern Wisconsin, U.S., in a small portion of their tradi�  tional territory along the Menominee River at the present-day Wisconsin-  Michigan border. Their name is derived from an Ojibwa word meaning  �person of the wild rice.� Their language is a member of the Algonquian  language family. At the time of first contact, the Menominee lived in vil�  lages of dome-shaped houses and collected wild plants, fished, and hunted  to obtain food. Originally organized into clans, their social organization  changed as a result of the fur trade, when they scattered in mobile bands.  In 1852 the U.S. government moved most of the tribe to a reservation in  Wisconsin. Sporadic uprisings occurred into the early 20th century, and  political opposition was renewed in the 1960s and �70s. There are about  8,000 enrolled members of the Menominee.</p><p>menopause Final cessation of menstruation, ending female fertility. It  usually begins between ages 45 and 55. A gradual decline in function of  the ovaries reduces estrogen production. Ovulation becomes irregular and  gradually ceases. The length of the menstrual cycle and periods may vary;  flow may lessen or increase. Adjustment of the endocrine system to estro�  gen reduction causes hot flashes, often at night, with a warm sensation,  flushing, and sweating; other symptoms, such as irritability and head�  aches, may be related more to reactions to aging. Removal or destruction  of the ovaries to treat disease causes artificial menopause, with similar  but more sudden effects. Changes in hormone balance usually cause no  physical or mental disturbances. However, the protective effect of estro�  gen against osteoporosis and atherosclerosis is lost, and risks of fracture  and coronary heart disease increase.</p><p>menorah \m3-'nor-3\ Multibranched candelabra used by Jews during  the festival of Hanukkah. It holds  nine candles (or has nine receptacles  for oil). Eight of the candles stand for  the eight days of Hanukkah�one is  lit the first day, two the second, and  so on. The ninth candle, or sham-  mash (�servant�) light�usually set  in the centre and raised above the  others�is used to light the others.</p><p>The menorah is an imitation of the  seven-branched golden candelabra  of the Tabernacle, which signified the  seven days of creation.

The group evolved in 1903  when L. Martov called for a mass party modeled after western European  groups, as opposed to Vladimir Iuch Lenin�s plan to restrict the party to pro�  fessional revolutionaries. When Lenin�s followers obtained a majority on  the party central committee, they called themselves Bolsheviks (�those of  the majority�), and Martov and his group became the Mensheviks (�those  of the minority�). The Mensheviks played active roles in the Russian  Revolution of 1905 and in the St. Petersburg soviet, but they became  divided over World War I and later by the Russian Revolution of 1917.  They attempted to form a legal opposition party but in 1922 were perma�  nently suppressed.</p><p>Menshikov Ymyen-shi-kdfX, Aleksandr (Danilovich) (b. Nov. 16,  1673, Moscow, Russia�d. Nov. 23, 1729, Berezov, Siberia, Russian  Empire) Russian soldier and administrator. In 1686 he became an orderly  for Peter I and soon was the tsar�s favourite. Menshikov led troops to vic�  tories in the Second Northern War, including the Battle of Poltava, after  which he received the title of field marshal (1709). As an administrator  from 1714, he was criticized for corrupt practices as he amassed power  and wealth. After Peter�s death in 1725, Menshikov succeeded in having  his ally Catherine I proclaimed empress, making him the virtual ruler of  Russia. After her death in 1727, he arranged to have his daughter marry  the young Tsar Peter II, but his enemies turned Peter against him and forced  Menshikov�s exile to Siberia.</p><p>menstruation Periodic discharge from the vagina of blood, secretions,  and shed mucous lining of the uterus (endometrium). The endometrium  prepares to receive a fertilized egg by thickening and producing secre�  tions. If the egg released by the ovary is not fertilized, the endometrium  breaks down and is expelled by contractions of the uterus. The first men�  struation (menarche) occurs after other changes of puberty, usually at  11-13 years of age, apparently triggered by the passing of a weight thresh�  old. Bleeding may be irregular or heavy at first. In adult women, men�  strual periods begin at an average interval of 28 days and last about five  days; some variation among women and in the same woman is normal.  Uterine contractions are felt as cramps. The amount of blood lost is usu�  ally less than 1.7 oz (50 ml). Menstruation ends with menopause. Men�  strual disorders include dysmenorrhea (painful menstruation) and  amenorrhea (no bleeding), heavy or light bleeding, and uterine bleeding. See  also PREMENSTRUAL SYNDROME.</p><p>mental disorder Any illness with a psychological origin, manifested  either in symptoms of emotional distress or in abnormal behaviour. Most  mental disorders can be broadly classified as either psychoses or neuro�  ses (see neurosis; psychosis). Psychoses (e.g., schizophrenia and bipolar dis�  order) are major mental illnesses characterized by severe symptoms such  as delusions, hallucinations, and an inability to evaluate reality in an objec�  tive manner. Neuroses are less severe and more treatable illnesses, includ�  ing DEPRESSION, ANXIETY, and PARANOIA as well as OBSESSIVE-COMPULSIVE DISORDERS</p><p>and post-traumatic stress disorders. Some mental disorders, such as Alzhe�  imer disease, are clearly caused by organic disease of the brain, but the  causes of most others are either unknown or not yet verified. Schizophre�  nia appears to be partly caused by inherited genetic factors. Some mood  disorders, such as mania and depression, may be caused by imbalances  of certain neurotransmitters in the brain; they are treatable by drugs that  act to correct these imbalances (see psychopharmacology). Neuroses often  appear to be caused by psychological factors such as emotional depriva�  tion, frustration, or abuse during childhood, and they may be treated  through psychotherapy. Certain neuroses, particularly the anxiety disorders  known as phobias, may represent maladaptive responses built up into the  human equivalent of conditioned reflexes.</p><p>mental hygiene Science of maintaining mental health and preventing  disorders to help people function at their full mental potential. It includes  all measures taken to promote and preserve mental health: rehabilitation  of the mentally disturbed, prevention of mental illness, and aid in coping  in a stressful world. Community mental health acknowledges the relation</p><p>between mental health, population pressures, and social unrest. It also  deals with social problems, from drug addiction to suicide prevention.  Treatment of the mentally ill through the ages has ranged from neglect,  ill treatment, and isolation to active treatment and integration into the  community, often in response to crusading reformers. Prevention of men�  tal illness includes prenatal care, child-abuse awareness programs, and  counseling for crime victims. Treatment includes psychotherapy, drug  therapy, and support groups. One of the most important efforts is public  education to combat the stigma still attached to mental illness and encour�  age those affected to seek treatment.</p><p>mental retardation Subaverage intellectual ability that is present  from birth or infancy and is manifested by abnormal development, learn�  ing difficulties, and problems in social adjustment. A standardized intel�  ligence test is a common method of identification. Individuals with IQ  scores of 53-70 are usually classified as mildly retarded and are able to  learn academic and pre-vocational skills with some special education.  Those with scores of 36-52 are classified as moderately retarded and are  able to learn functional academic skills and undertake semiskilled work  under supervised conditions. Those in the severe (21-35) and profound  (below 21) ranges require progressively more supervision or full-time  custodial care. Mental retardation can be caused by genetic disorders  (such as Down's syndrome), infectious diseases (such as meningitis), meta�  bolic disorders, poisoning from lead, radiation, or other toxic agents, inju�  ries to the head, and malnutrition.</p><p>menthol Crystalline organic compound of the isoprenoid family. It has  a strong, minty, cooling odour and taste. It is obtained from the oil of the  Japanese mint or made synthetically and is used in cigarettes, cosmetics,  chest rubs, cough drops, toothpastes, and flavourings. Of its two optical  isomers (see optical activity; isomerism), only 1-menthol has the desirable  cooling effect.</p><p>Menuhin Vmen-yo-wonX, Yehudi, Lord Menuhin of Stoke  d'Abernon (b.

In 1927 he studied with  George Enescu (1881-1955) in Paris; he returned to perform to tremen�  dous acclaim in New York the same year and went on to astound audi�  ences worldwide with his precocious depth and proficiency. From 1959  he lived in London, but he did not become a British citizen until 1985.  He directed the Bath Festival (1958-68) and the Gstaad Festival from  1956. In 1958 he founded his own chamber orchestra.

A successful lawyer, he  served as Australia�s attorney general (1934-39). Leader of the United  Australia Party, he served as prime minister (1939�41). He organized the  Liberal Party in 1944 and again became premier in 1949. In the 1950s he  fostered industrial growth in Australia and immigration from Europe. He  strengthened military ties with the U.S. and encouraged the ANZUS Pact  and Australia�s membership in the Southeast Asia Treaty Organization. He  retired in 1966 after the longest ministry in Australian history.</p><p>mer \'mer\ Among the Cheremi and Udmurt peoples of Russia, a sacred  grove where people of several villages gathered periodically to hold reli�  gious festivals and sacrifice animals to nature gods.

Mer festivals were infrequent; five years or more might  elapse between them.</p><p>mercantile agency Specialized organization that supplies informa�  tion on the creditworthiness and financial strength of business firms. The  first such agency, the Mercantile Agency, was founded in New York City  in 1841. It provided information to businesses that were expanding nation�  ally and were unable to assess the credit history of prospective custom�  ers in distant locations. It changed its name to R. G. Dun &amp; Co. after  1859 and merged with the Bradstreet Co. in 1933 to form Dun &amp; Brad-  street, Inc., the best-known mercantile agency. Mercantile agencies may  provide information on all types of business firms or may limit their  investigations to firms in a particular line of trade or a particular region.  Most agencies provide both general and special reports.

Though the theory existed earlier, the term was not coined until  the 18th century; it was given currency by Adam Smith in his Wealth of  Nations (1776). Mercantilism�s emphasis on the importance of gold and  silver holdings as a sign of a nation�s wealth and power led to policies  designed to obtain precious metals through trade by ensuring �favourable�  trade balances (see balance of trade), meaning an excess of exports over  imports, especially if a nation did not possess mines or have access to  them. In a favourable trade balance, payments for the goods or services  had to be made with gold or silver. Colonial possessions were to serve as  markets for exports and as suppliers of raw materials to the mother coun�  try, a policy that created conflict between the European colonial powers  and their colonies, in particular fanning resentment of Britain in the North  American colonies and helping bring about the American Revolution.  Mercantilism favoured a large population to supply labourers, purchasers  of goods, and soldiers. Thrift and saving were emphasized as virtues  because they made possible the creation of capital. Mercantilism provided  a favourable climate for the early development of capitalism but was later  severely criticized, especially by advocates of laissez-faire, who argued that  all trade was beneficial and that strict government controls were counter�  productive.</p><p>Mercator Vmsr-'ka-toA, Gerardus orig. Gerard Kremer (b.</p><p>March 5, 1512, Rupelmonde, Flanders�d. Dec. 2, 1594, Duisburg,  Duchy of Cleve) Flemish cartographer. He received a master�s degree in  1532 from the University of Louvain (Belgium), where he settled. By 24  he was a skilled engraver, calligrapher, and scientific-instrument maker.  He and his colleagues made Louvain a centre for construction of maps,  globes (terrestrial and celestial), and astronomical instruments. He was  appointed court cosmographer to Duke Wilhelm of Cleve in 1564, and in  1569 he perfected what has become known as the Mercator projection,  in which parallels and meridians are rendered as straight lines spaced so  as to produce at any point an accurate ratio of latitude to longitude. It  permitted mariners to steer a course over long distances, plotting straight  lines without continually adjusting compass readings. While the merid�  ians are equally spaced parallel vertical lines, the lines of latitude are  spaced farther and farther apart as their distance from the Equator  increases; on world maps the projection greatly enlarges areas distant from  the Equator.</p><p>mercenary Vmor-s^-.er-eV Hired professional soldier who fights for  any state or nation without regard to political principles. From the earli�  est days of organized warfare, governments supplemented their military  forces with mercenaries. After the Hundred Years� War (1337-1453),  Swiss soldiers were hired out all over Europe by their own cantonal gov�  ernments and won a high reputation. Rulers of the German state of Hesse  also hired out their soldiers, and Hessian troops fought for the British in  the American Revolution. Since the late 18th century, most mercenaries  have been individual soldiers of fortune.</p><p>Mercer, Johnny orig. John Herndon Mercer (b. Nov. 18, 1909,  Savannah, Ga., U.S.�d. June 25, 1976, Bel Air, Calif.) U.S. songwriter.  After moving to New York City in the late 1920s, Mercer began to write  lyrics while supporting himself as an actor. He later joined Paul White-  man�s orchestra as singer and master of ceremonies. In 1939 he joined  Benny Goodman�s Camel Caravan radio show. In 1942 Mercer cofounded  Capitol Records. On Broadway, he collaborated with Harold Arlen on St.  Louis Woman (1946) and Saratoga (1959) and also provided lyrics for  Seven Brides for Seven Brothers (1954), Li�l Abner (1956), and Foxy  (1964). His songs for films won four Academy Awards. He collaborated  with composers such as Hoagy Carmichael, Henry Mancini, Jerome Kern,  and Jimmy Van Heusen and is credited with more than 1,000 lyrics, includ�  ing those for �Ac-cent-tchu-ate the Positive,� �One for My Baby,�  �Autumn Leaves,� and �Moon River.�</p><p>mercerization X.mor-ss-ro-'za-shonX Chemical treatment applied to  cotton fibres or fabrics to make them permanently able to accept dyes  and various chemical finishes more easily. The method, patented in 1850  by the English calico printer John Mercer, also gives cotton cloth</p><p>increased tensile strength and greater absorptive properties. Higher-quality  cotton goods are usually mercerized. The treatment consists of dipping  the yam or fibre in a solution of sodium hydroxide and then treating the  material with water or acid to neutralize the sodium hydroxide.</p><p>merchandising Element of marketing concerned especially with the  sale of goods and services to customers. One aspect of merchandising is  advertising, which aims to capture the interest of the segment of the popu�  lation most likely to buy the product. Merchandising also involves prod�  uct display; companies provide retailers with display and promotional  materials and negotiate shelf space for their products. The development  of sales strategies includes the determination of pricing, discounts, and  special offers; the invention of sales pitches; and the identification of  avenues for sales, including store-based retailing and alternative means  such as direct-mail marketing, telemarketing, commercial Web sites, vend�  ing machines, and door-to-door sales.</p><p>Merchant, Ismail See James Ivory</p><p>merchant marine Commercial ships of a nation, whether privately or  publicly owned, and the personnel who operate such ships, as distinct  from the personnel of naval vessels.

One of the Anglo-  Saxon kingdoms of the Heptarchy, it comprised the border areas, corre�  sponding to modern Staffordshire, Derbyshire, Nottinghamshire, and  northern West Midlands and Warwickshire. Offa, who ruled from 757 to  796, created a single state from the River Humber to the English Chan�  nel. After Offa�s death, Mercia declined, overshadowed by Wessex. In 877  the Danes divided Mercia into English and Danish sections. After the  reconquest of the Danish lands in the early 10th century, it came under  the rule of Wessex.</p><p>Mercury In Roman religion, the god of merchants, commonly identified  with the Greek messenger of the gods, Hermes. His temple on Rome�s  Aventine Hill was dedicated in 495 bc. The goddess Maia was identified  as his mother, and the two were honoured in a festival on May 15. Mer�  cury is sometimes depicted holding a purse, symbolic of his business  functions. More often he is given the attributes of Hermes and portrayed  wearing winged sandals or a winged cap and carrying a caduceus.</p><p>mercury or quicksilver Metallic chemical element, chemical symbol  Hg, atomic number 80. Mercury is the only elemental metal that is liquid  at ordinary temperatures, with a freezing point of -38 �F (-39 �C) and a  boiling point of 674 �F (356.9 �C). Silvery white, dense, toxic (see mer�  cury poisoning), and a good conductor of electricity, mercury is occasion�  ally found free in nature but usually occurs as the red sulfide ore, cinnabar  (HgS). It has many uses�in dental and industrial amalgams, as a catalyst,  in electrical and measuring apparatus and instruments (e.g., thermom�  eters), as the cathode in electrolytic cells, in mercury-vapour lamps, and  as a coolant and neutron absorber in nuclear power plants. Many of mer�  cury�s compounds, in which it has valence 1 or 2, are pigments, pesti�  cides, and medicinals. It is a dangerous pollutant because it concentrates  in animal tissues in increasing amounts up the food chain.</p><p>Mercury Innermost planet of the solar system. Its average distance from  the Sun is about 36 million mi (58 million km), but its highly elliptical  orbit carries it 7.5 million mi (12 million km) nearer to and farther from  the Sun. It is the second-smallest major planet (after Pluto), having a  diameter of about 3,030 mi (4,880 km) and a mass about one-eighteenth  of Earth�s. With the shortest period of revolution (only 88 Earth days)  and the highest average orbital speed (30 mi/second, or 48 km/second) of  any planet, it is aptly named after the fleet-footed Roman messenger god.  It spins very slowly, making one complete rotation relative to the stars  every 59 Earth days, while its solar day (from one sunrise to the next) is  176 Earth days, owing to its revolution around the Sun. Its surface is  heavily cratered. Its most impressive feature is perhaps the 800-mi (1,300-  km) Caloris Basin, formed by a huge meteorite impact. Mercury also has  steep cliffs that extend for hundreds of miles. The discovery of a mag�  netic field in its vicinity suggests it has a large iron core, which would  account for a mean density almost as high as Earth�s. Its atmosphere is</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Mercury &#x25BA; Merimee I 1239</p><p>negligible; its surface gravity, about one-third that of Earth�s, holds an  exceedingly tenuous layer of gases. Temperatures at its surface change  dramatically, ranging from a high that can exceed 800 �F (425 �C) on the  sunward side to a low of about -290 �F (-180 �C) at the end of its night.</p><p>Mercury First series of U.S. manned spaceflights (1961-63), which  began about three weeks after Yury A. Gagarin became the first human  in space. In May 1961 Alan B. Shepard rode the first Mercury space cap�  sule, Freedom 7, on a 15-minute, 302-mi (486-km) suborbital flight,  attaining a maximum altitude of 116 mi (186 km). The first U.S. manned  flight in orbit was that of the Friendship 7, carrying John H. Glenn, Jr.,  in February 1962; it completed three orbits. The last Mercury flight, Faith  7, launched in May 1963, was the longest, making 22 orbits in about 34  hours.</p><p>mercury poisoning Harmful effects of mercury compounds. Manu�  facture of paints, various household items, and pesticides uses mercury;  the finished product and the waste products released into air and water  may contain mercury. The aquatic food chain can concentrate organic  mercury compounds in fish and seafood, which, if eaten by humans, can  affect the central nervous system, impairing muscle, vision, and cerebral  function, leading to paralysis and sometimes death (see Minamata disease).  Acute mercury poisoning causes severe digestive-tract inflammation.  Mercury accumulates in the kidneys, causing uremia and death. Chronic  poisoning, from occupational inhalation or skin absorption, causes metal�  lic taste, oral inflammation, blue gum line, extremity pain and tremor,  weight loss, and mental changes (depression and withdrawal). Drugs con�  taining mercury can cause sensitivity reactions, sometimes fatal. In young  children, acrodynia (pink disease) is probably caused by an organic mer�  cury compound in house paints.</p><p>Meredith, George (b. Feb. 1  Eng.�d. May 18, 1909, Box Hill,  Surrey) English novelist and poet.  Though ostensibly launched on a law  career at age 18, he concentrated  instead on writing poems and articles  and making translations. Because  they brought in little money, he  turned to writing prose. The novel  The Ordeal of Richard Feverel  (1859) is typical of his best work,  rich in allusion, metaphor, lyrical  prose, witty dialogue, and psycho�  logical insight. It failed to make him  wealthy, and he was forced to begin  reading manuscripts for a publisher.  Writing in his spare time, he pro�  duced a comedy, Evan Harrington  (1860), and a volume of poems,  Modern Love (1862). He finally won  critical and popular acclaim with the  novels The Egoist (1879) and Diana  of the Crossways (1885).

He won a legal battle to  be admitted, but federal troops and Justice Department officials had to be  brought in to enforce the court order. While participating in a voter-  registration drive after his graduation from �Ole Miss,� he was shot and  wounded by a white supremacist.</p><p>merengue \mo-'req-ga\ Couple dance from the Dominican Republic or  Haiti, danced throughout Latin America. Originally a folk dance, it has  become a ballroom dance, where it is danced with a limping step, the  weight always on the same foot. Varieties include the jaleo and juango-  mero. Dominican merengue music became widely popular in the late 20th  century.</p><p>mereology \,mir-e-'a-l3-je\ Branch of logic, founded by Stanislaw  Lesniewski, that studies class expressions and the relations between parts  and wholes. It rejects the hierarchy of sets generated in set theory through  the member-of relation and instead proposes a part-whole relationship. It</p><p>has attracted philosophers of logic and mathematics who are nominalists  (see universal), those who suspect set theory of being inherently Platonis-  tic, and those who are otherwise suspicious of the complex entities pro�  posed by, and the complicated assumptions needed for, set theory.</p><p>merganser or fish duck Any species of the diving duck genus Mer-  gus. Essentially freshwater birds, they are classified as a sea duck (tribe  Mergini). Mergansers have a long body and a narrow, serrated, hooked  bill for catching fish. The males of all but the common merganser, or  goosander (M. merganser), are crested. The common merganser, the  hooded merganser (M cucullatus), the red-breasted merganser (M. ser-  rator ), and the smew (M. albellus), a small, compact merganser with a  short bill, live in northern regions; the only southern species is the Bra�  zilian merganser (M. octosetaceus ). Mergansers are called trash ducks  because their flesh is rank. See also shelduck.</p><p>Mergenthaler Vmor-gon-.tha-brV Ottmar (b. May 11, 1854, Hach-  tel, Wtirttemberg�d. Oct. 28, 1899, Baltimore, Md., U.S.) German-U.S.  inventor. He immigrated to the U.S. in 1872. While working in a Balti�  more machine shop he began experimenting with type molds, and in 1884  he patented the Linotype typesetting machine. The reduced costs achieved  by thus speeding up the typesetting process led to a dramatic expansion  of all kinds of publishing.</p><p>merger Combination of two or more independent business corporations  into a single enterprise, usually involving the absorption of one or more  firms by a dominant firm. The dominant firm may purchase the other  firm�s assets with cash or securities, purchase the other firm�s stock, or  issue its own stock to the other firm�s stockholders in exchange for their  shares in the acquired firm (thus acquiring the other company�s assets and  liabilities). In horizontal mergers, both firms produce the same commod�  ity or service for the same market. In vertical mergers, a firm acquires  either a supplier or a customer. If the merged business is not related to  that of the acquiring firm, the new corporation is called a conglomerate.  The reasons for mergers are various: the acquiring firm may seek to  eliminate a competitor, to increase its efficiency, to diversify its products,  services, and markets, or to reduce its taxes.</p><p>Mergui Archipelago \m3r-'gwe\ Group of more than 200 islands in  the Andaman Sea off the coast of southeastern Myanmar.

It lies near the northwestern tip of the Yucatan Peninsula,  south of Progreso; its port is on the Gulf of Mexico. It was founded in  1542 on the site of the ancient Maya city of T�ho. It has numerous colo�  nial buildings and a 16th-century cathedral. Yucatan University and the  Regional Technical Institute of Merida are located there. It serves as a  tourist base for trips to nearby Maya cities, including Chichen ItzA, Dzi-  bilchaltun, Uxmal, and Kabah.</p><p>Merida Vma-re-tha\ ancient Emerita Augusta Town (pop., 2001:  50,271), capital of the autonomous community of Extremadura, western  Spain. Situated on the northern bank of the Guadiana River, it was  founded by the Romans in 25 bc. It served as the capital of the province  of Lusitania and became one of the most important towns in Iberia. Occu�  pied in ad 713 by the Moors, it was recaptured in 1228 by Alfonso IX of  Leon, who granted it to the Knights of Santiago. It is known for its Roman  ruins, including a bridge, an amphitheatre, and an aqueduct. The modern  town�s economy is based on agricultural trade and tourism.</p><p>Merimee \ma-re-'ma. Prosper (b.

In youth  a student of languages and literatures, he wrote his first play, Cromwell  (1922), at age 19. His passions were mysticism, history, and the unusual.  His stories, often mysteries, were inspired mainly by Spanish and Rus�  sian sources, notably Aleksandr Pushkin; they include Mateo Falcone  (1829), the collection Mosaique (1833), and the novellas Colombo (1840)  and Carmen (1845), the basis of Georges Bizet�s opera. He also wrote  works of history and archaeology, historical fiction, and literary criticism  and carried on correspondences that were published posthumously.

Angela Dorothea Kasner (b. July 17,  1954, Hamburg, W.Ger.) German politician and prime minister (2005- ).  Merkel, who grew up in East Germany, earned a doctorate in physics at  the University of Leipzig (1978) and later settled in East Berlin, where  she worked as a quantum chemist. In 1990, shortly before Germany�s  reunification, she joined the Christian Democratic Union (CDU). Elected  as a Bundestag deputy later that year, she became the protege of German  Chancellor Helmut Kohl, who appointed her to several ministerial posi�  tions. In 1999 a finance scandal hit the CDU, and Merkel drew attention  for her criticism of Kohl. The following year she was elected CDU leader.  In 2005 the CDU and its sister party, the Christian Social Union, won the  general election but failed to capture a majority. A deal was reached that  gave Merkel the chancellorship in a coalition government. She was sworn  in on Nov. 22, 2005, becoming the first woman to hold the office.</p><p>Merleau-Ponty \mer-lo-p6 n -'te\, Maurice (b. March 14, 1908,  Rochefort, France�d.

He was the  leading exponent of phenomenology in France. Though greatly influenced  by Edmund Husserl, he rejected Husserl�s theory of our knowledge of other  persons, grounding his own view instead in bodily behaviour and per�  ception. He defended Soviet communism until the Korean War, when he  became disillusioned.</p><p>Merlin Magician and wise man in Arthurian legend. In Geoffrey of Mon�  mouth�s History of the Kings of England, Merlin was an adviser to King  Arthur, with magical powers that recalled his Celtic origins. Later narra�  tives made him a prophet of the grail and gave him credit for the idea of  the Round Table. In Sir Thomas Malory�s Morte Darthur he brought Arthur  to the throne and served as his mentor throughout his reign. His down�  fall was linked to his infatuation for an enchantress, who imprisoned him  after learning the magic arts from him.</p><p>merlin or pigeon hawk Small blue-gray falcon ( Falco columbarius,  family Falconidae), with a narrowly white-banded tail, found at high lati�  tudes in Canada, the western U.S. south to Colorado, the British Isles,  Scandinavia, and Iceland.

Merman, who had  never taken voice lessons, worked as a secretary before her first profes�  sional singing engagement in 1929. She made her stage debut in George  and Ira Gershwin�s Girl Crazy (1930) (see George Gershwin; Ira Gersh�  win). Her brassy, ebullient style and powerful voice made her a favoured  performer for Irving Berlin, Cole Porter, and others. In the mid-1930s Mer�  man made her first Hollywood appearance, and she later starred on her  own radio show. Her many Broadway successes include Anything Goes  (1934), Red, Hot and Blue (1936), Annie Get Your Gun (1946), Call Me  Madam (1950), and Gypsy (1959).</p><p>Meroe \'mer-o-,we\ City, ancient Kush, northeastern Africa. Situated on  the eastern bank of the Nile River, north of modem Kabushiyyah, Sudan,  it was the southern administrative centre for the kingdom of Kush, begin�  ning c. 750 bc. After the sack of Napata (c. 590), it became the capital of  the kingdom. It included the region between the Nile and Atbara rivers,  where the Meroitic language developed. It survived a Roman invasion  but fell to Aksumite armies in the 4th century ad. The ruins of its temples  and palaces still exist near Kabushiyyah.</p><p>Merovingian X.mer-o-'vin-jonX art Visual arts produced under the  Merovingian dynasty of the 5th-8th centuries ad. They consisted mainly  of small-scale metalwork, little of which has survived, and several impor�  tant manuscripts. The style blends Roman Classical style with native  Germanic-Frankish traditions, which favoured abstraction and geometric  patterning. The human figure was rarely attempted; artists were concerned  primarily with surface design. Though modest, Merovingian art was influ�  ential long after the end of the dynasty.</p><p>Merovingian dynasty (476-750) Frankish dynasty considered the  first French royal house. It was named for Merovech (fl. c. 450), whose  son Childeric I (d. 482?) ruled a tribe of Salian Franks from his capital at  Tournai. His son, Clovis I, united nearly all of Gaul in the late 5th cen�  tury except Burgundy and present-day Provence. On his death the realm  was divided among his sons, but by 558 it was united under his last sur�  viving son, Chlotar I. The pattern of dividing and then reuniting the realm  continued for generations. After the reign of Dagobert I (623-639), the  authority of the Merovingian kings declined, and real power gradually  came to rest in the hands of the mayors of the palace. In 751 the last  Merovingian king, Childeric III, was deposed by Pippin III. the first of the  Carolingian dynasty.

Though his theories were eventually discredited, his abil�  ity to induce trance states in his patients made him the forerunner of the  modern use of hypnosis.</p><p>Mesoamerican civilization Complex of aboriginal cultures that  developed in parts of Mexico and Central America before the Spanish  conquest in the 16th century. This civilization and the Andean civilization  in South America constituted a New World counterpart to those of ancient  Egypt, Mesopotamia, and China. Humans have been present in  Mesoamerica from as early as 21,000 bc; a shift from hunting and gath�  ering to agriculture, which began c. 7000 bc as the climate warmed with  the end of the Ice Age, was completed by c. 1500 bc. The earliest great  Mesoamerican civilization, the Olmec, dates to c. 1150 bc. The Middle  Formative period (900-300 bc) was a time of increased cultural region�  alism and the rise of the Zapotec people. Civilizations of the Late Forma�  tive and Classic periods (lasting until c. ad 900) include the Maya and the  civilization centred at Teotihuacan; later societies include the Toltec and  the Aztec. See also Chichen Itza; Mixtec; Monte Alban; Nahua; Nahuatl  language; Tenochtitlan; Tikal.</p><p>Mesoamerican religions Religions of the pre-Columbian cultures  of Mexico and Central America, notably the Olmec, Maya, Toltec, and  Aztec. All religions of Mesoamerica were polytheistic. The gods had to  be constantly propitiated with offerings and sacrifices. The religions also  shared a belief in a multilevel universe that had gone through five cre�  ations and four destructions by the time of the Spanish conquest.  Mesoamerican religions heavily emphasized the astral bodies, particularly  the sun, the moon, and Venus, and the observations of their movements  by astronomer-priests were extraordinarily detailed and accurate. The  Aztecs approached the supernatural through a complex calendar of cer�  emonies that included songs, dances, acts of self-mortification, and human  sacrifices performed by a professional priesthood, in the belief that the  welfare of the universe depended on offerings of blood and hearts as  nourishment for the sun. The Mayan religion likewise called for human  sacrifices, though on a smaller scale. Information on the astronomical cal�  culations, divination, and ritual of the Mayan priests has been gathered  from the Maya Codices. See also Mesoamerican civilization.</p><p>Mesolithic \,me-z3-'li-thik\ Period or Middle Stone Age Ancient  technological and cultural stage (c. 8000-2700 bc) between the Paleolithic  and Neolithic periods in northwestern Europe. Mesolithic hunters, using  a tool kit of chipped and polished stone together with bone, antler, and  wooden tools, achieved a greater efficiency than their predecessors and  were able to exploit a wider range of animal and vegetable food sources.  Immigrant Neolithic farmers probably absorbed many indigenous  Mesolithic hunters and fishers. There is no direct counterpart to the  Mesolithic outside Europe, and the term is no longer used to reflect a  hypothetical worldwide sequence of sociocultural evolution.</p><p>meson \'me-,zan\ Any member of a family of subatomic particles com�  posed of a quark and an antiquark (see antimatter). Mesons are sensitive  to the strong force, have integral spin, and vary widely in mass. Though  unstable, many mesons last a few billionths of a second, long enough to  be observed with particle detectors. They are readily produced in the col�  lisions of high-energy subatomic particles (e.g., in cosmic rays).</p><p>Mesopotamia Region between the Tigris and Euphrates rivers in the  Middle East, constituting the greater part of modern Iraq. The region�s  location and fertility gave rise to settlements from c. 10,000 bc, and it  became the cradle of some of the world�s earliest civilizations and the  birthplace of writing. It was first settled by the Sumerians, who were suc�  ceeded by the Akkadians and later by the Babylonians. Successive peoples  came to dominate the region until the rise of the Persian Achaemenian  dynasty in the 6th century bc. The Achaemenids were overthrown by  Alexander the Great in the early 4th century bc, and Mesopotamia was  ruled by the Seleucid dynasty from c. 312 bc until the mid-2nd century bc,  when it became part of the Parthian empire. In the 7th century ad the  region was conquered by Muslim Arabs. The region�s importance  declined after the Mongol invasion in 1258. Rule by the Ottoman Empire  over most of the region began in the 16th century. The area became a  British mandate in 1920; the following year Iraq was established there.</p><p>Mesopotamian religions V.me-so-po-'ta-me-onV Religious beliefs  and practices of the Sumerians and Akkadians, and later of their succes�  sors, the Babylonians and Assyrians, who inhabited ancient Mesopotamia.  The deities of Sumer were usually associated with aspects of nature, such  as fertility of the fields and livestock. The gods of Assyria and Babylonia,  rather than displacing those of Sumer and Akkad, were gradually assimi�  lated into the older system. Among the most important of the many Meso�  potamian gods were Anu, the god of heaven; Enki, the god of water; and  Enlil, the earth god. Deities were often associated with particular cities.  Astral deities such as Shamash and Sin were also worshiped. The Meso�  potamians were skilled astrologers who studied the movements of the  heavenly bodies. Priests also determined the will of the gods through the  observation of omens, especially by reading the entrails of sacrificed ani�  mals. The king functioned as the chief priest, presiding at the new-year  festival held in spring, when the kingship was renewed and the triumph  of the deity over the powers of chaos was celebrated.</p><p>Mesozoic N.me-zo-'zo-ikV Era Second of the Earth�s three major geo�  logic eras and the interval during which the continental landmasses as  known today were separated from the supercontinents Laurasia and Gond-  wana by continental drift. It lasted from c. 248 to c. 65 million years ago  and includes the Triassic, Jurassic, and Cretaceous periods. The Mesozoic  saw the evolution of widely diversified and advanced flora and fauna,  quite different from those that had developed earlier during the Paleozoic  Era or that would develop later during the Cenozoic Era.</p><p>mesquite \m3-'sket\ Any of the spiny, deep-rooted shrubs or small trees  that make up the genus Prosopis of the pea family (see legume). Mesquites  form extensive thickets in areas from South America to the southwestern  U.S. Two races occur: one of tall trees (50 ft [15 m]), the other low and  far-reaching, called running mesquite. Water-seeking roots grow as deep  as 70 ft (20 m). Stems bear compound olive-green to white hairy leaves,  then dense, cream-coloured catkins of flowers, followed by clusters of  long, narrow, pale yellow beans. In warmer parts of the U.S., mesquites  are considered pests and are eradicated. Cattle eat the beans, which con�  tain a sweet pulp. The wood, formerly used in railroad ties, now has value  only for unusual furniture and trinkets and as aromatic firewood.</p><p>Mesrob Vmes-'ropV Saint or Saint Mesrop Mashtots \mash-'tots\  (b. c. 360, Hatsik, Armenia�d. Feb. 17, 440; Armenian feast day, Feb�  ruary 19) Armenian theologian and linguist. A scholar of classical lan�  guages, he became a monk c. 395 and eventually founded several  monasteries, spreading the Gospel in remote areas of Armenia. He sys�  tematized or invented the Armenian alphabet and sponsored the first trans�  lation of the Bible into Armenian (c. 410). He also wrote biblical  commentaries and translated other theological works, and he helped estab�  lish Armenia�s golden age of Christian literature. See also Armenian lan�  guage.</p><p>Messene \me-'sa-na, mo-'se-ne\ Ancient city, southwestern Peloponnese,  Greece. It is located north of the modem city of the same name. Founded  c. 369 bc as the site of the new capital of Messenia, Messene formed a  strategic bander against Sparta, along with Megalopolis, Mantinea, and  Argos. It survived several Macedonian and Spartan sieges but fell to Philip  II of Macedonia in 338 bc. Nothing is known of its history after the 2nd  century bc.</p><p>Messenia \m3-'se-ne-3\, Gulf of Gulf of the Ionian Sea, on the coast  of the southwestern Peloponnese, Greece. On the west side of the gulf is  the port of Koroni, originally settled by Argives after the First Messenian  War (c. 735-715 bc) and reoccupied during the Middle Ages by refugees  from the north. The French landed at the Gulf of Messenia in 1828 dur�  ing the War of Greek Independence to drive the Turks from the Peloponnese.</p><p>Messerschmitt, Willy (b. June 26, 1898, Frankfurt am Main, Ger�  man Empire�d. Sept. 17, 1978, Munich, W.Ger.) German aircraft  designer. From 1926 he was chief designer and engineer at the Bayerische  Flugzeugwerke in Augsburg, Ger., which in 1938 became Messerschmitt  AG. In 1939 his first military aircraft, the Messerschmitt 109 (Me 109),  set a speed record of 481 mph (775 km/hr). In World War II his factory  produced 35,000 Me 109�s for the German air force, as well as the Me  110 bomber, the Me 163 rocket-propelled plane, and the Me 262, the first  combat jet. Under a postwar ban on aircraft production, his firm made  prefab housing and sewing machines until 1958.</p><p>Messerschmitt 109 (Me 109) Fighter aircraft of Nazi Germany.

(BFW), it was also known as the Bf 109. Modified after see�  ing action in the Spanish Civil War, it became Germany�s premier fighter  for much of World War II. The model used in the Battle of Britain was a  single-seat, single-engine monoplane with a top speed of 350 mph (570  kph) and a ceiling of 35,000 ft (10,500 m). It was faster in a dive than  the British Spitfire but was limited in range by a small fuel capacity. By  1944 improved Allied fighters such as the P-51 had outstripped it.</p><p>Messiaen \mes-'ya n \, Olivier (-Eugene-Prosper-Charles) (b.</p><p>Dec. 10, 1908, Avignon, France�d.</p><p>April 27, 1992, Clichy, near Paris)</p><p>French composer. At age 11 he  entered the Paris Conservatoire,  where he won five first prizes. In  1931 he became principal organist at  the church of the Sainte-Trinite,  where he would remain for 40 years.</p><p>He wrote his Quartet for the End of  Time in a German POW camp. After  the war, he taught at the Conserva�  toire (1947-78), where his students  included Pierre Boulez, Karlheinz  Stockhausen, and Iannis Xenakis. His  main source of inspiration was his  quasi-mystical devout Catholic faith.</p><p>His love of nature is evident in his  many works inspired by birdsong.</p><p>He also was influenced rhythmically  by his study of Indian music, and he systematically explored nontonal  harmonic materials.

The term used for the messiah in the Greek New Testament, christos, was  applied to Jesus, who is accepted by Christians as the promised redeemer.  Messiah figures also appear in various other religions and cultures; Shiite  Muslims, for example, look for a restorer of the faith known as the mahdi,  and Maitreya is a redeeming figure in Buddhism.</p><p>Messier \mas-'ya,\ English \'me-se-,a\ catalog List of about 109 star  clusters, NEBULAe, and galaxies compiled by the French astronomer Charles  Messier (1730-1817), who discovered many of them.

Founded by Greeks in the 8th century bc, it was  destroyed by Carthaginians in 397 bc. The Romans took the rebuilt city  in 264 bc, precipitating the First Punic War. After the war it became a free  city allied with Rome. It was taken successively by the Goths, Byzan�  tines, Arabs, Normans, Spaniards, and finally (in 1860) Italians. Heavily  bombed during World War II, it was rebuilt. It is now an important Ital�  ian port.

It is 2 to 10 mi (3 to 16 km) wide.  The city of Messina lies on its bank in Sicily, opposite Reggio di Calabria.  Ferry service across the strait links Messina with the Italian mainland.</p><p>Mesta River See Nestos River</p><p>mestizo \mes-'te-zo\ Any person of mixed blood. In Spanish America  the term denotes a person of combined Indian and European extraction.  In some countries, such as Ecuador, it has acquired social and cultural  connotations: a pure-blooded Indian who has adopted European dress and  customs is called a mestizo (or cholo ). In Mexico the term�s meaning has  varied so greatly that it has been abandoned in census reports. In the Phil�  ippines it denotes a person of mixed foreign (e.g., Chinese) and native  ancestry. See also ladino.</p><p>metabolism \m3-'ta-b3- l li-z3m\ Sum of all the chemical reactions that  take place in every cell of a living organism, providing energy for the  processes of life and synthesizing new cellular material. The term inter�  mediary metabolism refers to the vast web of interconnected chemical  reactions by which all the cell�s constituents, many rarely found outside  it, are created and destroyed. Anabolic reactions use energy to build com�  plex molecules from simpler organic compounds (e.g., proteins from amino  acids, carbohydrates from sugars, fats from fatty acids and glycerol); cata-  bolic reactions break complex molecules down into simpler ones, releas�  ing chemical energy. For most organisms, the energy comes ultimately  from the Sun, whether they obtain it by photosynthesis and store it in  organic compounds or by consuming those organisms that do so. In some  bacteria in special environments such as deep-sea vents, the energy comes  from chemical reactions instead. Energy is transferred within the cell and  the organism by ATP; anabolic reactions consume it, and catabolic reac�  tions generate it. Every cellular chemical reaction is mediated by a spe�  cific enzyme. The process that breaks down a substance is usually not the  reverse of the process that makes it, using a different enzyme. See also  digestion; fermentation; glycolysis; tricarboxylic acid cycle.</p><p>Metabolist Vms-'ta-bo-listV school Japanese architectural movement  of the 1960s. Tange Kenzo launched the movement with his Boston Har�  bor Project design (1959), which included two gigantic A-frames hung  with �shelving� for homes and other buildings. Led by Tange, Isozaki  Arata, Kikutake Kiyonori (b. 1928), and Kurokawa Kisho (b. 1934), the  Metabolists focused on structures that combined high-tech imagery, Bru-  talism, and megastructures (multifunctional complexes that verge on self�  containment). The Metabolist manifestos put out at the World Design  Conference in 1960 paved the way for such later projects as Paolo Sol-  eri�s Arcosanti. Their advocacy of such devices as artificial land platforms  above cities, which grew out of a desire for economy of land use, revo�  lutionized architectural thinking.</p><p>Metacom Vme-ts-.kamX or Metacomet or King Philip (b. 1638,  Massachusetts�d. Aug. 12, 1676, Rhode Island) Wampanoag Indian  sachem (head of a confederation of Algonquian tribes). His father, Mas-  sasoit, had negotiated peace with the Pilgrims in 1621. Embittered by the  subsequent humiliations to which he and his people were continually sub�  jected by whites, Metacom in June 1675 led a confederation of  Wampanoag, Narragansett, Abenaki, Nipmuck, and Mohawk warriors into  battle. Known as King Philip�s War, the ensuing conflict was the most  brutal Indian war in New England history. After considerable loss of life  and property on both sides, the confederation began to disintegrate, and  food became scarce. Metacom returned to his ancestral home, where he  was betrayed and killed in 1676 by an Indian informant allied with the  colonists. He was beheaded and quartered, and his head was displayed on  a pole for 25 years at Plymouth.</p><p>metal Any of a class of substances with, to some degree, the following  properties: good heat and electricity conduction, malleability, ductility,  high light reflectivity, and capacity to form positive ions in solution and  hydroxides rather than acids when their oxides meet water. About three-  quarters of the elements are metals; these are usually fairly hard and strong  crystalline (see crystal) solids with high chemical reactivity that readily  form alloys with each other. Metallic properties increase from lighter to  heavier elements in each vertical group of the periodic table and from right  to left in each row. The most abundant metals are aluminum, iron, cal�  cium, sodium, potassium, and magnesium. The vast majority are found  as ores rather than free. The cohesiveness of metals in a crystalline struc�  ture is attributed to metallic bonding: The atoms are packed close together,  with their very mobile outermost electrons all shared throughout the struc�  ture. Metals fall into the following classifications (not mutually exclusive  and most not rigidly defined): alkali metals, alkaline earth metals, transition  elements, noble (precious) metals, platinum metals, lanthanide (rare earth)  metals, actinide metals, light metals, and heavy metals. Many have essen�  tial roles in nutrition or other biochemical functions, often in trace  amounts, and many are toxic as both elements and compounds (see mer�  cury POISONING, LEAD POISONING).</p><p>metal fatigue Weakened condition of metal parts of machines, vehicles,  or structures caused by repeated stresses or loadings, ultimately resulting  in fracture under a stress much weaker than that necessary to cause frac�  ture in a single application. Fatigue-resistant metals have been developed  and their performance improved by surface treatments, and fatigue  stresses have been significantly reduced in aircraft and other applications  by designing to avoid stress concentrations.</p><p>Olivier Messiaen.</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1244 I metal point &#x25BA; metasomatic replacement</p><p>L_</p><p>N</p><p>metal point or silverpoint Method of drawing with a small sharp�  ened metal rod�of lead, copper,  gold, or most commonly silver�on  specially prepared paper or parch�  ment. Silverpoint produces a fine  gray line that oxidizes to a light  brown; the technique is best suited  for small-scale work. It first  appeared in medieval Italy and  achieved great popularity in the 15th  century. Albrecht Durer and Leonardo  da Vinci were its greatest exponents.</p><p>It went out of fashion in the 17 th cen�  tury with the rise of the graphite pen�  cil but was revived in the 18th  century by the miniaturists and in the  20th century by Joseph Stella.</p><p>metallography \,me-t 3 l-'a-gr3-  fe\ Study of the structure of metals  and alloys, particularly using micro�  scopic and X-ray diffraction tech�  niques. Visual and optical  microscopic observation of metal  surfaces and fractures can reveal  valuable information about the crys�  talline, chemical, and mechanical  makeup of the material. In electron  microscopes a beam of electrons instead of a beam of light is directed onto  the specimen. The development of transmission electron microscopes has  made it possible to examine internal details of very thin metal foils. X-ray  diffraction techniques are used to study phenomena related to the grouping  of the atoms themselves. See also materials science, Henry C. Sorby.</p><p>metallurgy \'me-t a l- l 9r-je\ Art and science of extracting metals from  their ores and modifying the metals for use. Metallurgy usually refers to  commercial rather than laboratory methods. It also concerns the chemi�  cal, physical, and atomic properties and structures of metals and the prin�  ciples by which metals are combined to form alloys. Metals are extracted  from crude ore in two phases, mineral processing (also known as ore dress�  ing) and process metallurgy. In mineral processing, the ore is broken down  to isolate the desired metallic elements from the crude ore. In process  metallurgy, the resulting minerals are reduced to metal, alloyed, and made  available for use. See also blast furnace; powder metallurgy; smelting.</p><p>m eta logic Vme-to-.la-jikX Study of the syntax and the semantics of for�  mal languages and formal systems. It is related to, but does not include,  the formal treatment of natural languages (e.g., English, Russian, etc.).  Metalogic has led to a great deal of work of a mathematical nature in  axiomatic set theory, model theory, and recursion theory (in which func�  tions that are computable in a finite number of steps are studied).</p><p>metalwork Useful and decorative objects fashioned of various metals.  The oldest technique is hammering. After c. 2500 bc, casting was also  used, molten metal being poured into a mold and allowed to cool. Vari�  ous decorative techniques are used. Gold and silver have been worked  since ancient times. Gold and silver objects were in such demand in the  12th century that gold- and silversmiths organized guilds. High-quality  gold and silver objects were produced in pre-Columbian America. Copper  was worked in ancient Egypt and was widely used for household utensils  in 17th-18th-century Europe. Both bronze and brass were widely used in  ancient Greece. Pewter plates and tankards were made in the Middle Ages  and remained popular until they were superseded by cheaper earthenware  and porcelain in the 18th century. Wrought iron has been used for deco�  rative hinges, gates, and railings since the 16th century. Lead has tradi�  tionally been used for roof coverings.</p><p>metamorphic rock Any of a class of rocks that result from the alter�  ation of preexisting rocks in response to changing geological conditions,  including variations in temperature, pressure, and mechanical stress. The  preexisting rocks may be igneous, sedimentary, or other metamorphic  rocks. The structure and mineralogy reflect the particular type of meta�  morphism that produced the rock and the composition of the parent rock.  Metamorphic rocks are commonly classified by type of facies, predict�  able mineral assemblages associated with certain temperature and pres�  sure conditions (see, e.g., granulite facies).</p><p>metamorphism Mineralogic and structural changes in solid rocks  caused by physical conditions different from those under which the rocks  originally formed. Changes produced by surface conditions such as com�  paction are usually excluded. The most important agents of metamor�  phism are temperature (from 300�-2,200�F, or 150�-1200�C), pressure  (from 10 to several hundred kilobars, or 150,000 to several million lbs.  per sq in.), and stress. Dynamic metamorphism results from mechanical  deformation with little long-term temperature change. Contact metamor�  phism results from increases in temperature with minor differential stress,  is highly localized, and may occur relatively quickly. Regional metamor�  phism results from the general increase, usually correlated, of tempera�  ture and pressure over a large area and a long period of time, as in  mountain-building processes. See also metamorphic rock.</p><p>metamorphosis In biology, any striking developmental change of an  animal�s form or structure, accompanied by physiological, biochemical,  and behavioral changes. The best-known examples occur among insects,  which may exhibit complete or incomplete metamorphosis (see nymph).  The complete metamorphosis of butterflies, moths, and some other insects  involves four stages: egg, larva (caterpillar), pupa (chrysalis or cocoon),  and adult. The change from tadpole to frog is an example of metamor�  phosis among amphibians; some echinoderms, crustaceans, mollusks, and  tunicates also undergo metamorphosis.</p><p>metaphor Figure of speech in which a word or phrase denoting one kind  of object or action is used in place of another to suggest a likeness or  analogy between them (as in �the ship plows the seas� or �a volley of  oaths�). A metaphor is an implied comparison (as in �a marble brow�),  in contrast to the explicit comparison of the simile (�a brow white as  marble�). Metaphor is common at all levels of language and is funda�  mental in poetry, in which its varied functions range from merely noting  a likeness to serving as a central concept and controlling image.</p><p>Metaphysical painting Italian Pittura Metafisica Style of paint�  ing that flourished c. 1910-20 in the works of the Italian painters Gior�  gio de Chirico and Carlo Carra (1881-1966). The movement began with  Chirico, whose dreamlike works with sharp contrasts of light and shadow  often had a vaguely threatening, mysterious quality. Chirico, his younger  brother Alberto Savinio, and Carra formally established the school and its  principles in 1917. Their representational but bizarre and incongruous  imagery produces disquieting effects and had a strong influence on Sur�  realism in the 1920s.</p><p>Metaphysical poetry Highly intellectualized poetry written chiefly  in 17th-century England. Less concerned with expressing feeling than  with analyzing it, Metaphysical poetry is marked by bold and ingenious  conceits (e.g., metaphors drawing sometimes forced parallels between  apparently dissimilar ideas or things), complex and subtle thought, fre�  quent use of paradox, and a dramatic directness of language, the rhythm  of which derives from living speech. John Donne was the leading Meta�  physical poet; others include George Herbert, Henry Vaughan, Andrew  Marvell, and Abraham Cowley.</p><p>metaphysics Branch of philosophy that studies the ultimate structure  and constitution of reality�i.e., of that which is real, insofar as it is real.  The term, which means literally �what comes after physics,� was used to  refer to the treatise by Aristotle on what he himself called �first philoso�  phy.� In the history of Western philosophy, metaphysics has been under�  stood in various ways: as an inquiry into what basic categories of things  there are (e.g., the mental and the physical); as the study of reality, as  opposed to appearance; as the study of the world as a whole; and as a theory  of first principles. Some basic problems in the history of metaphysics are  the problem of universals �i.e., the problem of the nature of universals and  their relation to so-called particulars; the existence of God; the mind-body  problem; and the problem of the nature of material, or external, objects.  Major types of metaphysical theory include Platonism, Aristotelianism,  Thomism, Cartesianism (see also dualism), idealism, realism, and materialism.</p><p>metasomatic X.me-to-so-'ma-tikV replacement Process of simulta�  neous solution and deposition in which one mineral replaces another. It  is the method by which wood is petrified (silica replaces the wood fibres),  minerals form pseudomorphs (new minerals that preserve the character�  istic outward form of the earlier mineral that was replaced), or an ore  mineral assemblage takes the place of an earlier rock type. Replacement  minerals may themselves be replaced, and definite mineral successions  have been established. Replacement deposits may be highly valuable ore  deposits.</p><p>"Study of Hands/' silverpoint height�  ened with white on pink grounded  paper by Leonardo da Vinci; in Wind�  sor Castle/ Berkshire, Eng.</p><p>REPRODUCED BY GRACIOUS PERMISSION OF HER MAJESTY  QUEEN ELIZABETH II</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>metastable state &#x25BA; methanol I 1245</p><p>metastable V.me-to-'sta-boU state Excited state (see excitation) of an  atom, nucleus, or other system that has a longer lifetime than the ordinary  excited states and generally has a shorter lifetime than the ground state.

Antonio Domenico  Bonaventura Trapassi (b. Jan. 3, 1698, Rome�d. April 12, 1782,  Vienna) Italian poet and opera librettist. His name was changed by his  adoptive father, who left the youth enough money to embark on a career  as a poet. His first libretto, Didone abbandonata (1724), was so success�  ful that he was soon known throughout Italy. Important librettos such as  Enzio (1728) and Semiramide (1729) soon followed. He was invited to  Vienna as court poet by Charles VI. His 27 three-act librettos were set in  more than 800 operas in the 18th and early 19th century by composers  such as Antonio Vivaldi, George Handel, Christoph Gluck, Joseph Haydn,  Wolfgang Amadeus Mozart, and Luigi Cherubini.</p><p>Metaxas \,met-ak-'sas\ / loannis (b.

An ardent  monarchist, he left Greece when King Constantine I was deposed in 1917,  but he returned in 1920. After the monarchy�s fall in 1923, he led an  opposition ultraroyalist party until the monarchy was restored in 1935.  He was appointed premier in 1936 and, with royal authority, established  a dictatorship. He suppressed political opposition, carried out some ben�  eficial economic and social reforms, and brought a united country into the  Western alliance in World War II.</p><p>Metchnikoff \ , mech-ni- 1 kof\, Elie orig.

Most meteor showers come from matter released during passage  of a comet close to the Sun, and they recur annually as Earth crosses the  comet�s orbital path. Meteor showers are usually named for a constella�  tion (e.g., Leonid for Leo) or star in their direction of origin. Most show�  ers are visible as a few dozen meteors per hour, but occasionally Earth  crosses an especially dense concentration of meteoroids, as in the great  Leonid meteor shower of 1833, in which hundreds of thousands of mete�  ors were seen in one night all over North America.</p><p>meteorite Any interplanetary particle or chunk of stony or metallic  matter (meteoroid) that survives passage through Earth�s atmosphere and  strikes the ground or that reaches the surface of another planet or moon.

It has been widely used in heroin-  addiction programs in the U.S. since the 1960s. Though addictive itself,  it is easier to stop using than heroin. It also causes no euphoric effects and  does not lead to development of tolerance, so increasing doses are not  required.

The simplest member of the paraffin hydrocarbons,  methane burns readily, forming carbon dioxide and water if supplied with  enough oxygen for complete combustion or carbon monoxide if the oxy�  gen is insufficient. Mixtures of 5-14% methane in air are explosive and  have caused many mine disasters. The chief source of methane is natural  gas, but it can also be produced from coal. Abundant, cheap, and clean,  methane is used widely as a fuel in homes, commercial establishments,  and factories; as a safety measure, it is mixed with trace amounts of an  odorant to allow its detection.

Wesley, an Anglican clergyman, underwent an  epiphany in 1738 in which he felt an assurance of personal salvation, and  he soon began open-air preaching. Methodism began as a movement to  revitalize the Church of England and did not formally break with the  church until 1795. The Methodists� well-organized system of church gov�  ernment combined a strong central authority with effective local organi�  zation and the employment of lay preachers. Especially successful among  the working class in industrial areas, the movement expanded rapidly in  the 19th century. The Methodist Episcopal Church was founded in the  U.S. in 1784, and Methodist circuit riders won many followers on the  frontier. British and U.S. missionaries have since spread Methodism  throughout the world. Methodist doctrine emphasizes the power of the  Holy Spirit, the need for a personal relationship with God, simplicity of  worship, and concern for the underprivileged.</p><p>Methodius, St. See Sts.

For a small tax they enjoyed the protection of  the law and most of a citizen�s duties, including supporting public funds,  financing festivals, and serving in the military, but they could neither  marry a citizen nor own land. They were found in most states, Sparta being  an exception. In Athens they represented one-third of the free population.</p><p>Metis \ma-'tes\ In Canadian history, a person of mixed Indian and French  or Scottish ancestry. The first Metis were the offspring of local Indian  women and European fur traders in the Red River area of what is now  southern Manitoba. They call themselves the Forgotten People. Their lan�  guage, Michif, is a French and Cree trade language. Only a small per�  centage of people can speak Michif, although attempts are being made to  preserve it. For more than half a century the Metis cultivated a distinc�  tive way of life and came to think of themselves as a nation. The Metis  culture, particularly clothing, artwork, music, and dance, can be charac�  terized as colourful and unique. They resisted the Canadian takeover of  the Northwest in 1869, established a provisional government under the  leadership of Louis Riel, and in 1870 negotiated a union with Canada that  resulted in the establishment of the province of Manitoba. In 2003 Canada  granted the Metis legal recognition as a native group, with the same broad  hunting rights as full-status Indians. By the early 21st century the esti�  mated number of Metis in western Canada was more than 550,000.</p><p>metre Basic unit of length in the metric system and the International Sys�  tem of Units. In 1983 the General Conference on Weights and Measures  decided that the accepted value for the speed of light would be exactly  299,792,458 metres per second, so the metre is now defined as the dis�  tance traveled by light in a vacuum in 1/299,792,458 second. One metre  is equal to about 39.37 in. in the U.S. Customary System.</p><p>metre In poetry, the rhythmic pattern of a poetic line. Various principles  have been devised to organize poetic lines into rhythmic units. Quanti�  tative verse, the metre of Classical Greek and Latin poetry, measures the  length of time required to pronounce syllables, regardless of their stress;  combinations of long and short syllables form the basic rhythmic units.  Syllabic verse is most common in languages that are not strongly  accented, such as French or Japanese; it is based on a fixed number of  syllables within a line. Accentual verse occurs in strongly stressed lan�  guages, such as the Germanic; only stressed syllables within a line are  counted. Accentual-syllabic verse is the usual form in English poetry; it</p><p>combines syllable counting and stress counting. The most common  English metre, iambic pentameter, is a line of 10 syllables, or 5 iambic  feet; each foot contains an unstressed syllable followed by a stressed syl�  lable. Free verse does not follow regular metrical patterns. See also prosody.</p><p>metre See rhythm and metre</p><p>metric space In mathematics, a set of objects equipped with a concept  of distance. The objects can be thought of as points in space, with the  distance between points given by a distance formula, such that: (1) the dis�  tance from point A to point B is zero if and only if A and B are identical,  (2) the distance from A to B is the same as from B to A, and (3) the dis�  tance from A to B plus that from B to C is greater than or equal to the  distance from A to C (the triangle inequality). Two- and three-dimensional  Euclidean spaces are metric spaces, as are inner product spaces, vector spaces,  and certain topological spaces (see topology).</p><p>metric system International decimal system of weights and measures,  based on the metre (m) for length and the kilogram (kg) for mass, origi�  nally adopted in France in 1795. All other metric units were derived from  the metre, including the gram (g) for weight (1 cc of water at its maxi�  mum density) and the litre (1, or L) for capacity (0.001 cu m). In the 20th  century, the metric system became the basis for the International System  of Units, which is now used officially almost worldwide.</p><p>metrical foot See metrical foot</p><p>Metro-Goldwyn-Mayer, Inc.

A unit is an abstract idea,  defined either by reference to a randomly chosen material standard or to  a natural phenomenon. For example, the metre, the standard of length in  the metric system, was formerly defined (1889-1960) by the separation of  two lines on a particular metal bar, but it is now defined as the distance  traveled by light in a vacuum in 1/299,792,458 second.

Francisco Madero, Pancho Villa, Pascual  Orozco, and Emiliano Zapata amassed supporters, and in 1911 Madero was  declared president, but his slow-paced reforms alienated both former allies  and foes. He was deposed by Gen. Victoriano Huerta, whose own drunken  and despotic dictatorship quickly fell to Villa, Venustiano Carranza, and  Alvaro Obregon. Carranza declared himself president in 1914 over Villa�s  objections and, after further bloodshed, prevailed. He oversaw the writing  of the liberal constitution of 1917 but did little to implement its key pro�  visions; in 1920 he was killed while fleeing a rebellion.

It grew from a border dispute after the U.S.  annexed Texas in 1845; Mexico claimed that the southern border of Texas  was the Nueces River, while the U.S. claimed it was the Rio Grande. A  secret mission by John Slidell to negotiate the dispute and purchase New  Mexico and California for up to $30 million was aborted when Mexico  refused to receive him. In response to the snub, Pres. James Polk sent troops  under Zachary Taylor to occupy the disputed land between the two rivers.  In April 1846 Mexican troops crossed the Rio Grande and attacked Tay�  lor�s troops; Congress approved a declaration of war in May. Ordered to  invade Mexico, Taylor captured Monterrey and defeated a large Mexican  force under Antonio Santa Anna at the Battle of Buena Vista in February  1847. Polk then ordered Gen. Winfield Scott to move his army by sea to  Veracruz, capture the city, and march inland to Mexico City. Scott fol�  lowed the plan, meeting resistance at Cerro Gordo and Contreras, and  entered Mexico City in September. Under the Treaty of Guadalupe  Hidalgo, Mexico ceded to the U.S. nearly all of present New Mexico,  Utah, Nevada, Arizona, California, Texas, and Colorado for $15,000,000  and U.S. assumption of its citizens� claims against Mexico. Casualties  included about 13,000 American deaths, all but 1,700 of which were  caused by disease. The war, which made a national hero of Taylor,  reopened the slavery-extension issue supposedly settled by the Missouri  Compromise.</p><p>Mexico officially United Mexican States Country, southern North  America. The Rio Grande forms part of its northeastern border with the  U.S. Area: 758,449 sq mi (1,964,375 sq km). Population (2005 est.):  107,029,000. Capital: Mexico City. More than three-fifths of Mexico�s  people are mestizos, about one-fifth are American Indians, and the bulk of  the rest are of European ancestry. Languages: Spanish (official); more than  50 Indian languages are spoken. Religion: Christianity (predominantly  Roman Catholic; also Protestant). Currency: Mexican peso. Mexico has  two major peninsulas, the Yucatan in the southeast and Baja California in  the northwest. The high Mexican Plateau forms the core of the country  and is enclosed by mountain ranges: the Sierra Madre Occidental, the  Sierra Madre Oriental, and the Cordillera Neo-Volcanica. The last has the  country�s highest peak, the volcano Citlaltepetl, which reaches 18,406 ft  (5,610 m). Mexico has a mixed economy based on agriculture, manufac�  turing, and the extraction of petroleum and natural gas. About one-eighth  of the land is arable; major crops include com, wheat, rice, beans, cof�  fee, cotton, fruits, and vegetables. Mexico is the world�s largest producer  of silver, bismuth, and celestite. It has significant reserves of oil and natu�  ral gas. Manufactures include processed foods, chemicals, transport  vehicles, and electrical machinery. It is a republic with two legislative  houses; its head of state and government is the president. Humans may  have inhabited Mexico for more than 20,000 years, and the area produced  a string of great early civilizations, including the Olmec, Toltec, and Maya.  The Aztec empire, another important civilization located in Mexico, was  conquered in 1521 by Spanish explorer Hernan Cortes, who established  Mexico City on the site of the Aztec capital, TenochtitlAn.

Located at an elevation of 7,350 ft (2,240  m), it is officially coterminous with the Federal District, which occupies  571 sq mi (1,477 sq km). Mexico City is one of the world�s largest cities  and one of the world�s fastest-growing metropolitan areas. It generates  about one-third of Mexico�s industrial production. It lies on an ancient  lake bed, the site of the Aztec capital, Tenochtitlan, which was taken by  the Spanish explorer Hernan Cortes in 1521. It was the seat of the Vice�  royalty of New Spain throughout the colonial period. Captured by Mexi�  can revolutionaries under Gen. Agustfn de Iturbide in 1821, it was seized  by the U.S. in 1847 during the Mexican War and by the French (1863�  67) under Maximilian. It was greatly improved during the rule of Porfirio  Diaz (1876-80, 1884-1911). In 1985 it was struck by a severe earthquake  that killed at least 7,000 people. The old city centre, the Zocalo, has many  historic buildings, including the Metropolitan Cathedral (built on the site  of an Aztec temple) and the National Palace (built on the ruins of the  palace of Montezuma II). Its educational institutions include the National  Autonomous University of Mexico (founded 1551), the College of  Mexico, and the Ibero-American University. The city was designated a  UNESCO World Heritage Site in 1987.</p><p>Meyer Vml-orV Adolf (b. Sept. 13, 1866, Niederweningen, Switz.�d.  March 17, 1950, Baltimore, Md., U.S.) Swiss-born U.S. psychiatrist. He  immigrated to the U.S. in 1892 and taught principally at Johns Hopkins  University (1910-41). He developed a concept of human behaviour�  ergasiology, or psychobiology�that sought to integrate psychological and  biological study. Meyer emphasized accurate case histories, suggested a  role of childhood sexual feelings in mental problems in the years preced�  ing wide recognition of Sigmund Freud�s theories, and decided that men�  tal illness results essentially from personality dysfunction rather than brain  pathology. He became aware of the importance of social environment in  mental disorders, and his wife interviewed patients� families in what is  considered the first psychiatric social work.</p><p>Meyerbeer Vml-sr-.barX, Giacomo orig. Jakob Liebmann  Meyer Beer (b. Sept. 5, 1791, Tasdorf, near Berlin, Ger.�d. May 2,  1864, Paris, Fr.) German composer. Brother of the astronomer Wilhelm  Beer and the playwright Michael Beer, he achieved early success as a  pianist. After he studied vocal writing in Italy, his Italian operas were well  received. In Paris from c. 1825, he undertook work on a libretto by Eugene  Scribe, and his Robert le Diable (1831) was one of opera�s greatest tri�  umphs from its premiere. Three later grand operas also became part of the  international repertoire: Les Huguenots (1836), Le Prophete (1849), and  L�Africaine (1864). Richard Wagner�s criticism of Meyerbeer�s �deser�  tion� of German music, tainted by jealousy and anti-Semitism, led to  neglect of his music for many years, but Meyerbeer exercised unmistak�  able influence on both Giuseppe Verdi and Wagner himself.</p><p>Meyerhof VmI-9r- 1 hof\, Otto (b.

Feb. 2, 1940, Moscow) Russian theatrical pro�  ducer and director. He acted with the Moscow Art Theatre in 1898 and  formulated his avant-garde theories of symbolic theatre. Opposed to the  naturalism of Konstantin Stanislavsky, he directed plays in a nonrepresen-  tational style that became known as biomechanics. After 1908 he staged  plays in St. Petersburg that drew from commedia dell'arte and Asian the�  atre. He was noted for his direction of The Magnificent Cuckold (1920)  and for his controversial production of The Queen of Spades (1935). Con�  demned by Soviet critics for his artistic individuality and opposition to  Socialist Realism, he was arrested and imprisoned in 1939 and was prob�  ably executed.</p><p>mezzotint \'met-so-,tint\ (from Italian mezza tinta, �halftone�) Engrav�  ing produced by pricking the surface of a metal plate with innumerable  small holes that will hold ink. When the engraving is printed, the ink pro�  duces large areas of tone with soft, subtle gradations. Engraved or etched  lines are often introduced to give the design greater definition. Mezzotint  was invented in Holland by German-born Ludwig von Siegen in the 17th  century but thereafter was practiced primarily in England. Its adaptabil�  ity to making colour prints made it ideal for the reproduction of paintings.  After the invention of photography, it was rarely used. In recent years the  technique has been revived, especially by U.S. and Japanese printmakers.</p><p>Mfecane \em-fe-'ka-na\ (�The Crushing�) Series of Zulu and other  Nguni wars and forced migrations in the early 19th century that changed  the demographic, social, and political configuration of southern and cen�  tral Africa. Set in motion by the rise of the Zulu military kingdom under  Shaka, it took place in the context of drought, social unrest, and compe�  tition for trade. Ethnic group was set against ethnic group in an ever-  increasing radius, resulting in the creation of large refugee populations as  well as the establishment of new kingdoms under the Basuto, Gaza, Nde-  bele, and Swazi peoples.</p><p>MGM in full Metro-Goldwyn-Mayer, Inc. U.S. corporation and  film studio. It was formed when the film distributor Marcus Loew, who  bought Metro Pictures in 1920, merged it with the Goldwyn production  company in 1924 and with Louis B. Mayer Pictures in 1925. Louis B.  Mayer was executive head of the studio for 25 years, assisted by produc�  tion manager Irving Thalberg. It reached its peak in the 1930s and �40s,  when it had most of Hollywood�s famous stars under contract. It produced  such hits as Grand Hotel (1932), The Philadelphia Story (1940), Gaslight  (1944), Ben-Hur (1959), Doctor Zhivago (1965), and 2001: A Space  Odyssey (1968). It was especially celebrated for its lavish musicals,  including The Wizard of Oz (1939), On the Town (1949), An American in  Paris (1951), Singin� in the Rain (1952), and Gigi (1958). MGM began  to decline in the 1950s and sold off many of its assets in the 1970s. It  diversified into hotels and casinos and later merged with United Artists  Corp. as MGM/UA Entertainment. In 1986 it was bought by Ted Turner,  who resold the production and distribution units. Various transfers of  ownership led to its purchase in 1992 by Credit Lyonnais, which restored  the name MGM Inc. It was subsequently bought by Tracinda Corp.</p><p>MI5 in full Military Intelligence (Unit 5) British Security Service.  Originally organized in 1909 to counter German espionage, in 1931 it  assumed wider responsibility for assessing threats to national security,  including communist subversion and subsequently fascism. Today the  Security Service Act (1989) forms its statutory basis. As Britain�s  domestic-security intelligence agency, its purpose is to protect the coun�  try against threats such as terrorism, espionage, and subversion. Since the  passing of the Security Service Act (1996), its role has been expanded to  include supporting law-enforcement agencies in the field of organized  crime.</p><p>Miami North American Indian people who live mostly in Oklahoma and  Indiana, U.S. They call themselves Twit wee (Twatwa), which to them  represents the call of the crane.

The southernmost large  city in the continental U.S., it has a beach 7 mi (11 km) long. A Spanish  mission was founded near the site in 1567, but permanent settlement did  not begin until 1835, when U.S. forces built Fort Dallas for the removal  of Seminole Indians to the West. The arrival of the railway in 1896 spurred  development, and Miami was incorporated the same year. The city has  been damaged by occasional hurricanes, notably in 1926 and 1935. Nearly  300,000 Cuban refugees have arrived since 1959 (see Cuba), establishing  �Little Havana� within the city. It is a major resort and retirement centre,  and its port handles the world�s largest number of cruise-ship passengers.  It is also a banking centre. Educational institutions include the University  of Miami and Florida International University.</p><p>Miami Beach City (pop., 2000: 87,933), southeastern Florida, U.S. It  is situated on an island across Biscayne Bay from Miami. Until 1912 the site  was a mangrove swamp. John S. Collins and Carl F. Fisher pioneered real  estate development and built a bridge across the bay; the area was dredged  to form an island measuring 7.4 sq mi (19 sq km), with an 8-mi (13-km)  beach. The city, incorporated in 1915, is now a luxury resort and con�  vention centre. It is connected with Miami by several causeways and is  noted for its Art Deco architecture.</p><p>Miao See Hmong</p><p>Miao-Yao languages See Hmong-Mien languages</p><p>mica Vml-koV Any of a group of hydrous potassium, aluminum silicate  minerals that exhibit a two-dimensional sheet, or layer, structure. A very  abundant variety of mica is muscovite; two other common varieties are  biotite and phlogopite. Micas have various industrial uses. The varieties  that contain little iron are used as thermal or electrical insulators in appli�  ances and in such electrical devices as capacitors. In ground form, micas  are used in the manufacture of wallpaper, roofing paper, and paint. Ground  micas also serve as lubricants, absorbents, and packing material.</p><p>mica, black See biotite</p><p>Micah Vml-koX (fl. 8th century bc) One of the 12 Minor Prophets in the  Bible, traditional author of the book of Micah. (His prophecy is part of a  larger book, The Twelve, in the Jewish canon.) He probably began to  prophesy before the fall of the northern kingdom of Israel in 721 bc.  Modern scholars usually attribute the book�s first three chapters, which  predict judgment from God on idolaters and unjust leaders, to Micah.  Much of the rest, which promises the establishment of a kingdom of peace  in Zion, probably dates from several centuries later.</p><p>Michael In the Bible and the Qur�an, one of the archangels. The captain  of the heavenly hosts, he was invoked by early Christian armies against  the heathen. In Christian tradition he is thought to escort the soul into the  presence of God at the time of death. In art he is depicted as a warrior,  sword in hand, in triumph over a dragon. His feast day, known in England  as Michaelmas, is September 29. See also MikaIl.</p><p>Michael (b. Oct. 25, 1921, Sinaia, Rom.) King of Romania. After his  father, the future king Carol II, had been excluded from the royal succes�  sion (1926), Michael was proclaimed king under a three-member regency.  Carol reclaimed the throne in 1930, and Michael was reduced to crown  prince. With Carol�s abdication in 1940, Michael again became king but  was in effect a prisoner of the military dictator Ion Antonescu. In 1944  he helped lead the coup that overthrew the military regime and severed  Romania�s ties with the Axis powers. He strongly opposed the commu�  nists� subsequent rise to power, but was forced to abdicate in 1947. He  went into exile in Switzerland and became an executive with a U.S. bro�  kerage firm. In 1997 his Romanian citizenship was restored; he subse�  quently visited the country and sought the return of property holdings that  were confiscated.</p><p>Michael or Michael Romanov Nro-'ma-nof, 'ro-mo-.nafX Russian</p><p>Mikhail Fyodorovich Romanov (b.

A young nobleman elected as tsar after the chaotic Time of  Troubles, he allowed his mother�s relatives to direct the government early  in his reign. They restored order to Russia and made peace with Sweden</p><p>(1617) and Poland (1618). In 1619 his father, released from captivity in  Poland, returned to Russia and became coruler. Michael�s father domi�  nated the government, increasing contact with western Europe and  strengthening central authority and serfdom. After his death in 1633,  Michael�s maternal relatives once again held sway.</p><p>Michael VIII Palaeologus \,pa-le-'al-9-g9s\ (b. 1224 or 1225�d.  Dec. 11, 1282, Thrace) Nicaean emperor (1259-61) and Byzantine  emperor (1261-82), founder of the Palaeologan dynasty. Appointed regent  for the six-year-old son of Theodore II (1258), he seized the throne and  blinded the rightful heir. He recovered Constantinople from the Latins  (1261) and allied with the pope against his rivals, briefly reuniting Greek  and Roman churches in 1274 (see Councils of Lyon). In 1281 the new  pope, Martin IV, excommunicated him and declared Charles of Anjou�s  planned campaign against Byzantium to be a holy Crusade against the  schismatic Greeks. The Sicilian Vespers prevented Charles�s expedition and  thus saved Byzantium from a second occupation by the Latins.</p><p>Michael Cerularius X.ker-u-'lar-e-osN (b. c. 1000, Constantinople�d.  Jan. 21, 1059, Madytus, near Constantinople) Greek Orthodox patriarch  of Constantinople (1043-58). He thwarted Constantine IX�s efforts to ally  the Byzantine and Roman empires against the Normans, and he closed  Latin churches in Constantinople that refused to use the Greek language  and liturgy (1052). When negotiations broke down between Michael and  the papal legates sent by Leo IX, each side excommunicated the other, ini�  tiating the Schism of 1054. Michael forced Constantine to support the  schism, but in 1058 he was exiled by Constantine�s successor.</p><p>Michelangelo (di Lodovico Buonarroti) (b. March 6, 1475,  Caprese, Republic of Florence�d. Feb. 18, 1564, Rome, Papal States)  Italian sculptor, painter, architect, and poet. He served a brief apprentice�  ship with Domenico Ghirlandaio in Florence before beginning the first of  several sculptures for Lorenzo de'Medici. After Lorenzo�s death in 1492,  he left for Bologna and then for Rome. There his Bacchus (1496-97)  established his fame and led to a commission for the Pieta (now in St.  Peter's Basilica), the masterpiece of his early years, in which he demon�  strated his unique ability to extract two distinct figures from one marble  block. His David (1501-04), commissioned for the cathedral of Florence,  is still considered the prime example of the Renaissance ideal of perfect  humanity. On the side, he produced several Madonnas for private patrons  and his only universally accepted easel painting, The Holy Family (known  as the Doni Tondo). Attracted to ambitious sculptural projects, which he  did not always complete, he reluctantly agreed to paint the ceiling of the  Sistine Chapel (1508-12). The first scenes, depicting the story of Noah, are  relatively stable and on a small scale, but his confidence grew as he pro�  ceeded, and the later scenes evince boldness and complexity. His figures  for the tombs in Florence�s Medici Chapel (1519-33), which he designed,  are among his most accomplished creations. He devoted his last 30 years  largely to the Last Judgment fresco in the Sistine Chapel, to writing poetry  (he left more than 300 sonnets and madrigals), and to architecture. He  was commissioned to complete St. Peter�s Basilica, begun in 1506 and  little advanced since 1514. Though it was not quite finished at Michelan�  gelo�s death, its exterior owes more to him than to any other architect.  He is regarded today as among the  most exalted of artists.</p><p>Michelet \mesh-Te\, Jules (b.</p><p>Aug. 21, 1798, Paris, France�d.</p><p>Feb. 9, 1874, Heyres) French nation�  alist historian.

His time there  provided him with unique resources  for his life�s work, the 17-volume  Histoire de France (1833-67). His  method, an attempt to resurrect the  past by immersing his own person�  ality in his narrative, resulted in a  historical synthesis of great dramatic  power, though the 11 volumes that  appeared from 1855 to 1867 are dis�  torted by his hatred of priests and  kings, hasty or abusive treatment of  documents, and mania for symbolic  interpretation.

It introduced pneumatic tires for automobiles  in the 1890s and soon became one of the major European tire producers.  Michelin opened its first foreign plant in Turin in 1906 and has since  expanded production in many countries; it was reorganized as a holding  company in 1951.

May 9, 1931, Pasadena, Calif., U.S.) Prussian-born  U.S. physicist. His family immigrated to the U.S. in 1854. He studied at  the U.S. Naval Academy and in Europe and later taught principally at the  University of Chicago (1892-1931), where he headed the physics depart�  ment. He invented the interferometer, with which he used light to make  extremely precise measurements. He is best remembered for the  Michelson-Morley experiment, undertaken with Edward W. Morley (1838�  1923), which established that the speed of light is a fundamental constant.  Using a more refined interferometer, Michelson measured the diameter of  the star Betelgeuse, the first substantially accurate determination of the  size of a star. In 1907 he became the first American scientist to receive a  Nobel Prize.</p><p>Michelson-Morley experiment Attempt to detect the velocity of  the Earth with respect to ether, a hypothetical medium in space formerly  proposed to carry light waves. It was first performed in Berlin in 1881 by  A.A. Michelson and refined in the U.S. in 1887 by Michelson and Edward  W. Morley (1838-1923). The procedure assumed that if the speed of light  were constant with respect to the ether, the motion of the Earth could be  detected by comparing the speed of light in the direction of the Earth�s  motion and the speed of light at right angles to the Earth�s motion. No  difference was found, and the result discredited the ether theory. As a  result, Albert Einstein proposed in 1905 that the speed of light is a univer�  sal constant.</p><p>Michener Vmich-noA, James A(lbert) (b. Feb. 3, 1907?, New York,  N.Y., U.S.�d.

From 1944 to 1946 he was a naval historian in  the South Pacific, the setting of his early fiction; his Tales of the South  Pacific (1947, Pulitzer Prize) was adapted as the Broadway musical South  Pacific (1949; film, 1958). He is best known for epic and detailed novels  drawing on extensive research, including Hawaii (1959; film, 1966), Ibe�  ria (1968), Centennial (1974), Chesapeake (1978), Space (1982), and  Mexico (1992).</p><p>Michigan State (pop., 2000: 9,938,444), midwestern U.S. Surrounded  almost entirely by the Great Lakes, it is divided into two large land seg�  ments: the Upper and Lower peninsulas. The Lower Peninsula is bordered  to the south by Indiana and Ohio; the Upper Peninsula is bounded by  Wisconsin to the west. Michigan, including the Great Lakes, covers  96,716 sq mi (250,493 sq km); its capital is Lansing. The western region  of the Upper Peninsula is a rugged upland rich in minerals, and the  remainder of the state consists of lowlands and rolling hills. The area was  originally inhabited by ALGONQUiAN-speaking Indians. The French arrived  in the 17th century, founding Sault Ste. AAarie in 1668 and Detroit in 1701;  fur trading was their primary activity. The English gained control of  Michigan in 1763 following the French and Indian War, and it passed to  the U.S. in 1783. It was included in the Northwest Territory in 1787 and  in Indiana Territory in 1800. Michigan Territory was organized on the  Lower Peninsula in 1805. Though surrendered to the British in the War  of 1812, U.S. rule was restored in 1813 by the victory of Oliver Hazard  Perry at the Battle of Lake Erie. A boundary dispute with Ohio, known as  the Toledo War, was settled by U.S. President Andrew Jackson, with  Michigan receiving the Upper Peninsula and statehood as compensation.  In 1837 it became the 26th U.S. state. Throughout the American Civil War,  it made major contributions to the Union cause. In the 20th century its  economy was dominated by the automotive industry.</p><p>Michigan, Lake Third largest of the five Great Lakes and the only one  lying wholly within the U.S. Bordered by the states of Michigan, Wis�</p><p>consin, Illinois, and Indiana, it connects with Lake Huron through the  Straits of Mackinac in the north.

U.S. government grants constitute the main source of revenue; subsistence  farming and fishing are the principal economic activities. Micronesia is a  republic in free association with the U.S.; it has one legislative house, and  its head of state and government is the president. The islands were prob�  ably settled by people from eastern Melanesia some 3,500 years ago. They  were colonized by Spain in 1886 and came under Japanese rule after  World War I. They were captured by U.S. forces during World War II, and  in 1947 they became part of the UN Trust Territory of the Pacific Islands,  administered by the U.S. The islands became an internally self-governing  federation in 1979. In 1982 it signed a compact of free association with  the U.S., which is responsible for Micronesia�s defense.</p><p>microphone Device for converting sound waves into electric power  that has wave characteristics essentially similar to those of the sound. By  proper design, a microphone may be given directional characteristics so  that it will pick up sound primarily from a single direction, from two  directions, or more or less uniformly from all directions. In addition to  their use in telephone transmitters, microphones are most widely applied  in hearing aids, sound-recording systems (principally magnetic and digi�  tal tape recorders), and public-address systems.</p><p>In a moving-coil microphone, sound waves cause the diaphragm to vibrate, and  this oscillating motion causes a wire voice coil to move back and forth through a  magnetic field, generating a current that varies in proportion to the original sound  wave.

Microsoft, head�  quartered in Redmond, Wash., also publishes books and multimedia titles  and manufactures hardware. It was founded in 1975 by Bill Gates and Paul  G. Allen (b. 1954), who adapted BASIC for use on personal computers.  They licensed versions of it to various companies, developed other pro�  gramming languages, and in 1981 released MS-DOS for the IBM PC. The  subsequent adoption of MS-DOS by most other personal-computer manu�  facturers generated vast revenues for Microsoft, which became a publicly  owned corporation in 1986. It issued the first version of Microsoft Word,  its popular word-processing program, in 1983, and Microsoft Windows,  a graphical user interface for MS-DOS-based computers, in 1985.

Microwaves have wavelengths  ranging from 30 cm to 1 mm, corresponding to frequencies from about 1  gigahertz (10 9 Hz) to 1 terahertz (10 12 Hz). They are the principal car�  riers of television, telephone, and data transmissions between stations on  Earth and between the Earth and satellites. Radar beams are short pulses  of microwaves used to locate ships and planes, track weather systems,  and determine the speeds of moving objects. Microwaves are absorbed by  water and fat in foodstuffs and produce heat from the inside (see micro-  wave oven). Materials such as glass and ceramics do not absorb micro-  waves, and metals reflect them.

A microwave oven is a relatively  small, boxlike oven that raises the temperature of food by subjecting it  to a high-frequency electromagnetic field. The microwaves are absorbed by  water, fats, sugars, and certain other molecules, whose resulting vibra�  tions produce heat. The heating thus occurs inside the food, without warm�  ing the surrounding air.

In the 5th cen�  tury the Western Roman Empire endured declines in population, economic  vitality, and the size and prominence of cities. It also was greatly affected  by a dramatic migration of peoples that began in the 3rd century. In the  5th century these peoples, often called barbarians, carved new kingdoms  out of the decrepit Western Empire. Over the next several centuries these  kingdoms oversaw the gradual amalgamation of barbarian, Christian, and  Roman cultural and political traditions. The longest-lasting of these king�  doms, that of the Franks, laid the foundation for later European states. It  also produced Charlemagne, the greatest ruler of the Middle Ages, whose  reign was a model for centuries to come. The collapse of Charlemagne�s  empire and a fresh wave of invasions led to a restructuring of medieval  society. The 11th�13th centuries mark the high point of medieval civili�  zation. The church underwent reform that strengthened the place of the  pope in church and society but led to clashes between the pope and  emperor. Population growth, the flourishing of towns and farms, the emer�  gence of merchant classes, and the development of governmental bureau�  cracies were part of cultural and economic revival during this period.  Meanwhile, thousands of knights followed the call of the church to join  the Crusades. Medieval civilization reached its apex in the 13th century  with the emergence of Gothic architecture, the appearance of new reli�  gious orders, and the expansion of learning and the university. The church  dominated intellectual life, producing the Scholasticism of St. Thomas  Aquinas. The decline of the Middle Ages resulted from the breakdown of  medieval national governments, the great papal schism, the critique of  medieval theology and philosophy, and economic and population collapse  brought on by famine and disease.</p><p>Middle Congo See Republic of the Congo</p><p>Middle East or Mideast or Near East Geographic region where  Europe, Africa, and Asia meet.

U.S. intelligence had broken the Japanese naval code,  and the U.S. prepared for the assault by mobilizing about 115 land-based  aircraft as well as three aircraft carriers. On June 3 its bombers began  striking Japan�s carrier force. Japan was unable to match the U.S. air  power and, after heavy losses, abandoned efforts to land on Midway.

The company originated in 1939 within another Soviet design bureau  as a department under Artem Mikoyan and his deputy, Mikhail Gurevich.  Three years later it became the independent bureau OKB-155. Its first  design, a single-engine interceptor (first flown 1940), eventually bore the  name MiG-1 (�MiG� being an acronym based on �Mikoyan� and �Gure�</p><p>vich�). After World War II it produced the first Soviet jet fighter, the  MiG-9 (1946), and followed on with some of the U.S.S.R.�s most notable  high-speed aircraft (see MiG [fighter aircraft]). The last major fighters  designed under Mikoyan (died 1970) were the variable-wing MiG-23  (entered service 1972), and the MiG-25 (introduced 1970; capable of  about Mach 3). The organization later produced several new designs,  including the MiG-29 and MiG-31 (both first flown in the 1970s). In the  late 1980s its formal name became ANPK imeni A.I. Mikoyana. In the  1990s, after the breakup of the Soviet Union, MiG was consolidated with  several other major firms into the giant state-owned aerospace complex  VPK MAPO.

Some migraine patients have warning symptoms (an �aura�) before  the headache, including visual disturbance, weakness, numbness, or diz�  ziness. If a stimulus (e.g., a particular food or drink) is found to trigger  attacks, avoidance can prevent them. Drugs may be taken as an attack  begins (to abort it) or daily by patients with very frequent attacks (to pre�  vent them or reduce their severity).</p><p>migrant labour Semiskilled or unskilled workers who move from one  region to another, offering their services on a temporary, usually seasonal,  basis. In North America, migrant labour is generally employed in agri�  culture and moves seasonally from south to north following the harvest.  In Europe and the Middle East, migrant labour usually involves urban  rather than agricultural employment and calls for longer periods of resi�  dence. The migrant labour market is often disorganized and exploitative.  Many workers are supervised by middlemen such as labour contractors  and crew leaders, who recruit and transport them and dispense their pay.  Labourers commonly endure long hours, low wages, poor working con�  ditions, and substandard housing. In some countries, child labour is wide�  spread among migrant labourers, and even in the U.S. those children who  do not work often do not go to school, since schools are usually open  only to local residents. Workers willing to accept employment on these  terms are usually driven by even worse conditions in their home coun�  tries. Labour organizing is made difficult by mobility and by low rates of  literacy and political participation, though some migrant labourers in the  U.S. have been unionized. See also Cesar Chavez.</p><p>migration, human Permanent change of residence by an individual  or group, excluding such movements as nomadism and migrant labour.  Migrations may be classed as internal or international and as voluntary  or forced. Voluntary migration is usually undertaken in search of a better  life; forced migrations include expulsions during war and the transporta�  tion of slaves or prisoners. The earliest humans migrated from Africa to  all the continents except Antarctica within about 50,000 years. Other mass  migrations include the forced migration of 20 million people as slaves  from Africa to North America in the 16th-19th centuries and the Great  Atlantic Migration of 37 million people from Europe to North America  between 1820 and 1980. War-related forced migrations and refugee flows  continue to be very large, as are voluntary migrations from developing  nations to industrialized ones. Internal migrations have tended to be from  rural areas to urban centers.</p><p>mihrab \'me-rob\ Arabic mihrab Semicircular prayer niche in the  qiblah wall (the wall facing Mecca) of a MOSQUE, reserved for the prayer  leader {imam). The mihrab originated in the reign of the Umayyad caliph  al-Walld I (705-715), when the famous mosques at Medina, Jerusalem,  and Damascus were built. It was adapted from the prayer niches common  in Coptic Christian monasteries. Mihrabs are usually ornately decorated.</p><p>MTka�Tl \mi-'kal\ In Islam, the counterpart of the biblical archangel  Michael.

His support of Joseph Stalin earned him a post on the  Communist Central Committee (1923). He was commissar of trade from  1926, a member of the Politburo from 1935, and deputy premier (1946-  64), directing the country�s trade.

The area was settled  by the Gauls c. 600 bc. Known as Mediolanum, it was conquered by the  Romans in 222 bc. Attacked in ad 452 by Attila and in 539 by the Goths,  it fell to Charlemagne in 774. Milan�s power grew in the 11th century, but  it was destroyed by the Holy Roman Empire in 1162. Rebuilt as part of the  Lombard League in 1167, Milan achieved independence in 1183. In 1450  Francesco Sforza founded a new dynasty there; after 1499 it was ruled  alternately by the French and the Sforza family until 1535, when the Hab-  sburgs obtained it. Napoleon took power in 1796, and in 1805 it became  the capital of his kingdom of Italy. It was incorporated into unified Italy  in 1860. Milan was heavily damaged during World War II but was rebuilt.  It is Italy�s most important economic centre, with industrial development  and textile manufacturing. It is noted for its fashion industry and produc�  tion of electronic goods and is also Italy�s financial centre. Its historic  sites include the medieval Duomo, Europe�s third largest cathedral; the  Palazzo di Brera (1651); the 15th-century monastery that houses Leonardo  da Vinci�s Last Supper, and La Scala opera house.</p><p>Milan Decree (Dec. 17, 1807) Economic policy in the Napoleonic  Wars.

Before 500  bc it was the greatest Greek city in the east. Distinguished as a commer�  cial and colonial power, it was also known for its intellectual figures,  including Thales, Anaximander, Anaximenes, and Hecataeus. Ruled by  Greek tyrants, it later passed successively under the control of Lydia and  the Persian Achaemenian dynasty. About 499 bc Miletus led the Ionian  revolt that sparked the Persian Wars, and it was destroyed by the Persians  in 494 bc. After the Greeks defeated the Persians, it joined the Delian  League. It fell to Alexander the Great in 334 bc but retained its commer�  cial importance. By the 6th century ad its two harbours had silted up, and  it was eventually abandoned. Now an archaeological site, it is located near  the mouth of the Menderes River.</p><p>Milford Sound Inlet of the Tasman Sea, southwestern coast of South  Island, New Zealand. About 2 mi (3 km) wide, the sound extends inland  for 12 mi (19 km). It was named by a whaler in the 1820s for its resem�  blance to Milford Haven in Wales. It is the northernmost fjord in Fiord�  land National Park and is the site of Milford Sound town, one of the  region�s few permanently inhabited places.</p><p>Milhaud \me-'y6\, Darius (b. Sept. 4, 1892, Aix-en-Provence,  France�d. June 22, 1974, Geneva, Switz.) French composer. Milhaud  studied at the Paris Conservatoire, then at the Schola Cantorum with Vin�  cent d'Indy. He became known as one of Les Six, a group of young French  composers. His music is characterized by polytonality (simultaneous use  of different keys), as in Saudades do Brazil (1921); though dissonant, his  compositions retain a lyrical quality. The influence of jazz is audible in  his best-known work, the ballet The Creation of the World (1923). He  wrote many ballets, operas, and film scores in the 1920s, culminating in  the grand opera Christophe Colomb (1928). Milhaud had a longtime asso�  ciation with the Aspen Music Festival, which he helped found in 1949.</p><p>miliaria V.mi-le-'ar-e-oX Inflammatory skin disorder, with multiple small  sites at sweat pores. Blockage of ducts causes sweat to escape into vari�  ous levels of the skin and produce different inflammatory reactions. The  most common type, known as prickly heat, results when sweat escapes  into the epidermis. Pinhead blisters or pimplelike bumps occur mostly on  the trunk and limbs and cause itching and burning. It mainly affects infants  in tropical climates. See also perspiration, sweat gland.</p><p>Military Academy, U.S. See United States Military Academy</p><p>military engineering Art and practice of designing and building  military works and of building and maintaining lines of military transport  and communications. It includes both tactical support (see tactics) on the  battlefield, including construction of fortifications and demolition of  enemy installations, and strategic support (see strategy) away from the  front lines, such as construction or maintenance of airfields, ports, roads,  railroads, bridges, and hospitals. Its most notable feat in ancient times was  the Great Wall of China. The preeminent military engineers of the ancient  Western world were the Romans, who maintained their power by con�  structing not only forts and garrisons but roads, bridges, aqueducts, har�  bors, and lighthouses. See also civil engineering.</p><p>military government Administration of territory by an occupying  power. The definition does not cover military forces stationed in neutral  or friendly territory that share administrative responsibilities with local  civil authorities. Military government must also be distinguished from  military law and martial law. Its control lasts until it either gives up power  voluntarily or is overthrown. The term is popularly used for rule of a  country by its own military, whether it comes to power through a COUP  d'etat or is the legitimate governing body.</p><p>military law Law prescribed by statute for governing the armed forces  and their civilian employees. It in no way relieves military personnel of  their obligations to their country�s civil code or to the codes of interna�  tional law. Mutiny, insubordination, desertion, misconduct, and other  offenses injurious to military discipline constitute violations of military  law; offenders may be subject to court-martial. Lesser offenses may be  penalized summarily by a commanding officer (e.g., through the with�  drawal of privileges or the cancellation of liberty).</p><p>military unit Group of a prescribed size with a specific combat role  within a larger military organization. The chief units in the ancient world</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>militia &#x25BA; Mill I 1257</p><p>were the Greek phalanx and the Roman legion. Modern units originated  in the 16th�18th century, when professional armies reemerged in Europe  after the end of the Middle Ages. Since then the basic units�company,  battalion, brigade, and division�have remained in use. The smallest unit  today is the squad, which has 7-14 soldiers and is led by a sergeant. Three  or four squads make up a platoon, and two or more platoons make up a  company, which has 100-250 soldiers and is commanded by a captain or  a major. Two or more companies make up a battalion, and several bat�  talions form a brigade. Two or more brigades, along with various spe�  cialized battalions, make up a division, which has 7,000-22,000 troops  and is commanded by a major general. Two to seven divisions make up  an army corps, commanded by a lieutenant general, which with 50,000-  300,000 troops is the largest regular army formation, though in wartime  two or more corps may be combined to form a field army (commanded  by a general), and field armies in turn may be combined to form an army  group.</p><p>militia \m3-'li-sh3\ Military organization of citizens with limited mili�  tary training who are available for emergency service, usually for local  defense. In many countries the militia is of ancient origin. The Anglo-  Saxons required every able-bodied free male to serve. In colonial America  it was the only defense against hostile Indians when regular British forces  were not available. In the American Revolution the militia, called the Min-  utemen, provided the bulk of the American forces. Militias played a simi�  lar role in the War of 1812 and the American Civil War. State-controlled  volunteer militias in the U.S. became the National Guard. British militia  units, begun in the 16th century for home defense and answerable to the  county sheriff or lord lieutenant, were absorbed into the regular army in  the 20th century. Today various paramilitary organizations, from U.S.  white supremacists to revolutionaries in the developing world, use the  term militia to accentuate their populist origins.</p><p>milk Liquid secreted by the mammary glands of female mammals to  nourish their young. The milk of domesticated animals is also an impor�  tant food source for humans. Most milk consumed in Western countries  is from cows; other important sources include sheep, goats, water buffalo,  and camels. Milk is essentially an emulsion of fat and protein in water,  along with dissolved sugar, minerals (including calcium and phosphorus),  and vitamins, particularly vitamin B complex. Commercially processed cow�s  milk is commonly enriched with vitamins A and D. Many countries  require pasteurization to protect against naturally occurring and artificially  introduced microorganisms. Cooling further prevents spoilage (souring  and curdling). Fat from whole milk (about 3.5% fat content) can be  removed in a separator to produce cream and leave low-fat milk (1-2%  fat) or skim milk (0.5% fat). Milk is usually homogenized, forced under  high pressure through small openings to distribute the fat evenly. It may  also be condensed, evaporated, or dehydrated for preservation and ease  of transport. Other dairy products include butter, cheese, and yogurt.</p><p>Milk, Harvey (Bernard) orig. Glimpy Milch (b. May 22, 1930,  Woodmere, Long Island, N.Y., U.S.�d. Nov. 27, 1978, San Francisco,  Calif.) U.S. political leader. After graduating from college, he served in  the U.S. Navy and was discharged in 1955 (although Milk claimed that  he was dishonourably discharged due to his homosexuality, military  records do not support the allegation). He later settled in San Francisco  and soon gained a following as a leader of the city�s gay community. In  1977 he was elected to the city�s Board of Supervisors, becoming one of  the first openly gay elected officials in U.S. history. In 1978 Milk and the  city�s mayor, George Moscone (1929-78), were shot and killed in City  Hall by Dan White, a conservative former city supervisor. At White�s  murder trial, his attorneys argued that his judgment had been impaired by  eating junk food (a tactic later derided as the �Twinkie defense�); his con�  viction on the less serious charge of voluntary manslaughter sparked riots  in the city. Milk was the subject of numerous books and movies, includ�  ing the 1984 documentary The Times of Harvey Milk, which received an  Academy Award.</p><p>Milken, Michael R. (b. July 4, 1946, Encino, Calif., U.S.) U.S. fin-  ancier and entrepreneur. He studied at the University of Pennsylvania�s  Wharton School and went to work in 1969 for what was to become Drexel  Burnham Lambert Inc., an investment-banking company. In 1971 he  became head of its bond-trading department. He persuaded many of his  clients to invest in junk bonds issued by new or financially troubled com�  panies; the capital he raised financed a new class of �corporate raiders�  who carried out numerous mergers, acquisitions, hostile takeovers, and  leveraged buyouts in the 1980s. By the end of the decade, the junk-bond</p><p>market was worth $150 billion, and Drexel was a leading financial firm.  In 1986 its client Ivan Boesky, convicted of insider trading, implicated  Milken and the firm in his dealings. Charged with securities fraud and  heavily fined, Drexel declared bankruptcy in 1990 when the junk-bond  market collapsed. Milken pled guilty to securities fraud the same year and  was sentenced to 10 years in prison and a $600-million fine; released after  22 months, he since made a second fortune.</p><p>milkweed family Family Asclepiadaceae, composed of about 2,000  species of flowering herbaceous plants or shrubby climbers in more than  280 genera. Most family members have milky juice, podlike fruits, and  tufted silky-haired seeds that drift on wind currents to new locations for  sprouting. Common milkweed (Asclepias syriaca) and bloodflower {A.  curassavica) often are cultivated as ornamentals. Hoya carnosa, com�  monly called wax plant because of its waxy white flowers, is often grown  indoors as a potted plant. The family also includes some succulents, some  PITCHER PLANTS, and BUTTERFLY WEED.</p><p>Milky Way Galaxy Large spiral galaxy (roughly 150,000 light-years  in diameter) that contains Earth�s soiar system. It includes the multitude  of stars whose light is seen as the Milky Way, the irregular luminous band  that encircles the sky defining the plane of the galactic disk. The Milky  Way system contains hundreds of billions of stars and large amounts of  interstellar gas and dust. Because the dust obscures astronomers� view of  many of its stars, large areas could not be studied before the development  of infrared astronomy and radio astronomy (see radio and radar  astronomy). Its precise constituents, shape, and true size and mass are still  not known; it is believed to contain large amounts of dark matter and a  massive black hole at its core. The Sun lies in one of the Galaxy�s spiral  arms, about 27,000 light-years from the centre.</p><p>Mill, James (b. April 6, 1773, Northwater Bridge, Forfarshire,  Scot.�d. June 23, 1836, London, Eng.) Scottish philosopher, historian,  and economist. After studying at the University of Edinburgh and teach�  ing, he went to London in 1802, where he met Jeremy Bentham and became  a major promulgator of Bentham�s utilitarianism. He wrote for several  journals, including the Edinburgh Review (1808-13), and contributed  articles on government and education to the Encyclopaedia Britannica.  He helped found London University in 1825. After completing his His�  tory of British India (3 vol., 1817), he was appointed an official in India  House (1819) and later became head of the examiner�s office (1830). His  criticism of British rule led to changes in the government of India. His  Elements of Political Economy (1821) summarized the views of David  Ricardo, and his Analysis of the Phenomena of the Human Mind (1829)  associated psychology with utilitarianism, a doctrine continued by his son,  John Stuart Mill. Mill is considered the founder of philosophical radical�  ism.</p><p>Mill, John Stuart (b. May 20, 1806, London, Eng.�d. May 8, 1873,  Avignon, France) British philosopher and economist, the leading exposi�  tor of utilitarianism. He was educated exclusively and exhaustively by his  father, James Mill. By age 8 he had read in the original Greek Aesop�s  Fables, Xenophon�s Anabasis, and all of Herodotus, and he had begun a  study of Euclid�s geometry; at age 12 he began a thorough study of scho�  lastic logic. In 1823 he cofounded the Utilitarian Society with Jeremy  Bentham, though he would later significantly modify the utilitarianism he  inherited from Bentham and his father to meet the criticisms it encoun�  tered. In 1826 he and Bentham cofounded London University (now Uni�  versity College). From 1828 to 1856 he was an assistant examiner in India  House, where from 1836 he was in charge of the East India Company�s  relations with the Indian states. In the 1840s he published his great sys�  tematic works in logic and political economy, chiefly A System of Logic  (2 vol., 1843) and Principles of Political Economy (2 vol., 1848). As head  of the examiner�s office in India House from 1856 to 1858 he wrote a  defense of the company�s government of India when the transfer of its  powers was proposed. In 1859 he published On Liberty, a trenchant  defense of individual freedom. His Utilitarianism (1863) is a closely rea�  soned attempt to answer objections to his ethical theory and to address  misconceptions about it; he was especially insistent that �utility� include  the pleasures of the imagination and the gratification of the higher emo�  tions and that his system include a place for settled rules of conduct. In  1869 he published The Subjection of Women (written 1861), now the clas�  sical theoretical statement of the case for woman suffrage. Prominent as  a publicist in the reforming age of the 19th century, he remains of lasting  interest as a logician and ethical theorist.

In the  1920s, when she lived in Greenwich Village, she came to personify the  romantic rebellion and bravado of youth. Among her volumes are Rena�  scence (1917); A Few Figs from Thistles (1920); The Harp Weaver (1923,  Pulitzer Prize); The Buck in the Snow (1928), which introduced a more  sombre tone; the sonnet sequence Fatal Interview (1931); and Wine from  These Grapes (1934).</p><p>Mi lie, Agnes de See Agnes de Mille</p><p>millefleurs tapestry \mel-'fbrz\ French "thousand flowers"</p><p>Tapestry characterized by a background motif of many small flowers.

There are two expressions of millennialism. Premil-  lennialism holds that the Second Coming of Christ will occur before the  millennium and will initiate the final battle between good and evil, which  will be followed by the establishment of the 1,000-year kingdom on earth  or in heaven. Postmillennialism maintains that Jesus will return after the  creation of the millennial kingdom of peace and righteousness, which  prepares the way for the Second Coming. Throughout the Christian era,  periods of social change or crisis have tended to lead to a resurgence in  millennialism. The legend of the last emperor and the writings of Joachim  of Fiore are important examples of medieval millennialism, and, during  the Reformation, Anabaptists, Bohemian Brethren, and other groups held  millennial beliefs. It is now associated especially with such Protestant  denominations as the Adventists, Jehovah's WiTNESSes, and Mormons. In a  broader sense, many non-Christian traditions, including Pure Land Bud�  dhism and the Ghost Dance religion, are understood as millennialist.</p><p>millennium Period of 1,000 years. The Gregorian calendar, put forth  in 1582 and subsequently adopted by most countries, did not include a  year 0 in the transition from bc (years before Christ) to ad (those since  his birth). Thus, the 1st millennium is defined as spanning years 1-1000</p><p>and the 2nd years 1001-2000.

Both larvae and adults of most species feed at night. Adults feed on fruits,  sap, and nectar. The larvae of many species are agricultural pests (e.g.,  cutworm, bollworm) that feed on foliage and seeds, bore into stems and  fruits, and eat or sever roots. A few species prey on scale insects.</p><p>Miller, Arthur (b. Oct. 17, 1915, New York, N.Y., U.S.�d. Feb. 10,  2005, Roxbury, Conn.) U.S. playwright.

His first important play, All My  Sons (1947), was followed by his most famous work, Death of a Sales�  man (1949, Pulitzer Prize), the tragedy of a man destroyed by false val�  ues that are in large part the values of his society. Noted for combining  social awareness with a searching concern for his characters� inner lives.

In Plans and the Structure  of Behavior (with Eugene Galanter and Karl Pribram, 1960), Miller exam�  ined how knowledge is accumulated and organized into a practical  �image� or plan. His other works, including Language and Communica�  tion (1951) and The Science of Words (1991), focus on the psychology of  language and communication. He received the National Medal of Science  in 1991.</p><p>Miller, (Alton) Glenn (b. March 1, 1904, Clarinda, Iowa, U.S.�d.  Dec. 16, 1944, at sea) U.S. trombonist and leader of one of the most  popular dance bands of the swing era. Miller formed his band in 1937.  His music was characterized by the precise execution of arrangements that  featured a clarinet leading the saxophone section. Miller disbanded in  1942 to join the war effort by leading a military band. He was traveling  from London to Paris by plane when the craft disappeared over the  English Channel and was never recovered. His recordings of numbers  such as �Moonlight Sonata,� �Chattanooga Choo-Choo,� �In the Mood,�  and �String of Pearls� are classics of the era.</p><p>Miller, Henry (Valentine) (b. Dec. 26, 1891, New York, N.Y.,  U.S.�d. June 7, 1980, Pacific Pali�  sades, Calif.) U.S. writer and peren�  nial bohemian. Miller wrote about  his Brooklyn, N.Y., childhood in  Black Spring (1936). Tropic of Can�  cer (1934), a monologue about his  life as an impoverished expatriate in  Paris, and Tropic of Capricorn  (1939), which draws on his earlier  New York phase, were banned as  obscene in the U.S. and Britain until  the 1960s. The Air-Conditioned  Nightmare (1945) is a critical  account of a tour of the U.S. He  settled on the California coast, where  he became the centre of a colony of  admirers and wrote his Rosy Cruci�  fixion trilogy, Sexus, Plexus, and  Nexus (U.S. ed., 1965).</p><p>Miller, Jonathan (Wolfe) (b.</p><p>July 21, 1934, London, Eng.)

U.S. psychologist. He earned his Ph.D.  from Yale University and remained at Yale�s Institute of Human Rela�  tions to continue his experiments on learning. In Social Learning and  Imitation (1941) and Personality and Psychotherapy (1950), he and John  Dollard presented a theory of motivation based on the satisfaction of psy�  chosocial drives, combining elements of earlier reinforcement theories of  behaviour and learning. Miller suggested that behaviour patterns were  produced through the modification of biologically or socially derived  drives by conditioning and reinforcement. He taught at Rockefeller Uni�  versity (1966-81).</p><p>Millerand \mel-'ra n \, Alexandre (b. Feb. 10, 1859, Paris, France�d.  April 7, 1943, Versailles) French politician. He was an editor of socialist  journals (1883-98) and served in the Chamber of Deputies from 1885 to  1920. He implemented reforms while serving in various governments as  minister of commerce (1899-1901), public works (1909-10), and war  (1912-15). He became premier in 1920, and, as leader of a moderate coa�  lition, was elected president of France (1920-24). After advocating a  revision of the constitution to strengthen the power of the presidency, he  was forced to resign by the Cartel des Gauches. He served in the Senate  from 1927 to 1940.</p><p>millet Any of various grasses (family Poaceae, or Gramineae), that pro�  duce small edible seeds used as forage crops and as food cereals. Most  millets range in height from 1 to 4 ft (0.3 to 1.3 m). Except for pearl mil�  let ( Pennisetum glaucum , or P. americanum), seeds remain enclosed in  hulls after threshing. Cultivated in China since at least the 3rd millennium  bc, millets are today an important food staple in much of Asia, Russia,  and western Africa. High in carbohydrates, they are somewhat strong in  taste and cannot be made into leavened bread, so they are consumed  mainly in flatbreads and porridges or prepared and eaten much like rice.  In the U.S. and western Europe they are used chiefly for pasture or to  produce hay.</p><p>millet \mo-Tet\ Turkish term referring to an autonomous religious com�  munity under the Ottoman Empire (c. 1300-1923). Each millet was respon�  sible to the central government for obligations such as taxes and internal  security and also had responsibility for social and administrative func�  tions not provided by the state. Beginning in 1856, a series of secular  legal reforms known as the Tanzimat (�Reorganization�) eroded much of  their administrative autonomy.</p><p>Millet \me-'ya,\ English \mi-'la\, Jean-Francois (b. Oct. 4, 1814,  Gruchy, France�d. Jan. 20, 1875, Barbizon) French painter. Born to a  peasant family, he studied with a painter in Paris, but when one of his two  submissions to the Salon was rejected (1840), he returned to Cherbourg,  where initially he painted mostly portraits. His first success came with  The Milkmaid (1844), and in 1848 another peasant scene. The Winnower,  was shown at the Salon. In 1849 he settled in the village of Barbizon.  Because he continued to exhibit peasant scenes that emphasized the  labours of rustic life, he was accused of being a socialist, but his aims  were not political. His Angelus (1859) became one of the most popular  paintings of the 19th century. In his later life he was linked with the Bar�  bizon SCHOOL.</p><p>Millikan, Robert (Andrews) (b. March 22, 1868, Morrison, HI.,  U.S.�d. Dec. 19, 1953, San Marino, Calif.) U.S. physicist. He received  his doctorate from Columbia University and taught physics at the Uni�  versity of Chicago (1896-1921) and the California Institute of Technol�  ogy (from 1921). To measure electric charge, he devised the Millikan oil-  drop experiment. He verified Albert Einstein�s photoelectric equation and  obtained a precise value for the Planck constant. He was awarded a 1923  Nobel Prize.</p><p>Millikan oil-drop experiment Vmil-s-konX First method for direct  measurement of the electric charge of a single electron, originally per�  formed in 1909 by Robert Millikan. He used a microscope to measure the  rate of descent of tiny oil droplets directed through the top of a box. By  halting the descent of droplets carrying their own electric charge by means  of precisely adjusting the voltage between the box�s metal top and bot�</p><p>tom, he discovered that the electric charges on the drops were all whole-  number multiples of a lowest value, the elementary electric charge itself,  and thus that electric charge exists in basic natural units.</p><p>milling See fulling</p><p>milling machine Machine tool that rotates a circular tool with numer�  ous cutting edges arranged symmetrically about its axis, called a milling  cutter. The metal workpiece is usually held in a vise clamped to a table  that can move in three perpendicular directions. Cutters of many shapes  and sizes are available for a wide variety of milling operations. Milling  machines cut flat surfaces, grooves, shoulders, inclined surfaces, dove�  tails, and T-slots. Various form-tooth cutters are used for cutting concave  forms and convex grooves, for rounding comers, and for cutting gear  teeth.</p><p>millipede Any of about 10,000 species of the arthropod class  Diplopoda, found worldwide. Most species live in and eat decaying plant  matter. Some injure living plants, and a few are predators and scavengers.  Millipedes are 1�11 in. (2.5-28 cm) long and have from 11 to more than  100 diplosomites, double segments formed from the fusion of two seg�  ments. The head is legless; the next three segments have one pair of legs  each; and the remaining segments have two pairs each. In defense, mil�  lipedes do not bite; most species tuck headfirst into a tight coil, and many  secrete a pungent, toxic liquid or gas.</p><p>Mills, Billy in full William Mervin Mills (b. June 30, 1938, Pine  Ridge, S.D., U.S.) U.S. athlete. Part Oglala Sioux, he spent his early years  on a reservation in Pine Ridge and was orphaned at age 12. At the Uni�  versity of Kansas he excelled in track. He became the first American to  win an Olympic gold medal in the 10,000-m race (1964), in an electri�  fying upset victory over Australian Ron Clarke. In 1965 he set an outdoor  world record in the 6-mi run and U.S. records in the 10,000-m and indoor  3-mi races.</p><p>Mills, C(harles) Wright (b. Aug. 28, 1916, Waco, Texas, U.S.�d.  March 20, 1962, Nyack, N.Y.) U.S. sociologist. After studying at the Uni�  versity of Texas (B.A., M.A., 1939) and the University of Wisconsin  (Ph.D., 1941), Mills joined the faculty of Columbia University; there he  became associated with the theories of Max Weber and with issues regard�  ing the role of intellectuals in modern life, and he contributed to the  development of a critical sociology in the U.S. and abroad. Mills believed  social scientists should shun �abstracted empiricism� and become activ�  ists on behalf of social change. His radical analysis of U.S. business and  society appeared in White Collar (1951) and The Power Elite (1956);  other works include The Causes of World War Three (1958) and The  Sociological Imagination (1959). A colourful public figure, he wore black  leather and rode a motorcycle. His death at 45 resulted from heart dis�  ease.</p><p>Mill's methods Five methods of experimental reasoning distinguished  by John Stuart Mill in his System of Logic (1843). Suppose one is inter�  ested in determining what factors play a role in causing a specific effect,  E, under a specific set of circumstances. The method of agreement tells  us to look for factors present on all occasions when E occurs. The method  of difference tells us to look for some factor present on some occasion  when E occurs and absent on an otherwise similar occasion when it does  not. The joint method of agreement and difference combines the two pre�  vious methods. The method of residues applies when part of E is expli�  cable by reference to known factors, and tells us to attribute the �residue�  to the remaining circumstances under which E occurs. The method of  concomitant variation is used when E can be present in various degrees;  if we identify a factor F, such as temperature, whose variations are posi�  tively or negatively correlated with variations in E, for instance, size, then  we can infer that F is causally connected with E.</p><p>millstone Either of two flat, round stones used for grinding grain to  make flour. The stationary bottom stone is carved with shallow grooved  channels that radiate from the centre. The upper stone rotates horizon�  tally, and has a central hole through which grain is poured. The channels  of the bottom stone lead the grain onto the flat grinding section, called  the land, and to the edge, where it emerges as flour. The best millstones  are made from French buhrstone, quarried near Paris. In the U.S., quartz  conglomerate, quartzite, sandstone, or granite is used. Stone-ground flour  accounts for only a small proportion of milled flour today.</p><p>Milne Vmiln\, A(lan) A(lexander) (b. Jan. 18, 1882, London,  Eng.�d.

A Spanish  explorer charted the bay in 1606; it was named by the British for Adm.  Alexander Milne in 1873. European interest in it increased during the  1889-99 gold rush. Samarai, an island in the China Strait, became a  boomtown from which prospectors spread through the islands of Milne  Bay and to the mainland. As a Japanese base of operations in World War  II, Milne Bay was the scene of Japan�s first major setback in 1942, and  it served as an Allied base for the remainder of the war.</p><p>Milner, Alfred later Viscount Milner (of St. James's and  Cape Town) (b. March 23, 1854, Giessen, Hesse-Darmstadt�d. May  13, 1925, Sturry Court, near Canterbury, Kent, Eng.) British high com�  missioner in South Africa (1897-1905). At the crucial Bloemfontein Con�  ference with Pres. Paul Kruger (1899), Milner advocated granting full  citizenship to the Uitlanders (British residents in the Transvaal) after five  years� residence. Kruger opposed the policy but was prepared to make  concessions. Milner was not, claiming that �war has got to come�; Boer  forces invaded Natal four months later, marking the beginning of the  South African War. Milner later served as secretary for war (1916-19)  and colonial secretary (1919-21).</p><p>Milon Vmi- I lan\ of Croton or Milo of Croton (fl. late 6th century  bc) Ancient Greek athlete.

Aug. 29, 1941, Pozarevac,  Serbia, Yugos.�found dead March 11, 2006, The Hague, Neth.) Serbian  nationalist politician and president of Serbia (1989-97). He joined the  Communist Party at age 18 and later became head of the state-owned gas  company and president of a major Belgrade bank. Advised by his wife, a  communist ideologue, he became head of the Communist Party in Bel�  grade (1984) and later in Serbia (1987). He replaced party leaders with  his supporters, and in 1989 the Serbian assembly named him president of  the republic. He maintained his power by repression and control of the  mass media. He abrogated the constitutional autonomy of the Albanian  province of Kosovo in 1989, which contributed to the secessionist move�  ments in Slovenia, Croatia, and Macedonia and the breakup of Yugosla�  via in 1991. He then supported Serbian militias fighting Muslims in  Bosnia and Croatia (see Bosnian conflict) but later signed a peace agree�  ment (1995) on behalf of the Bosnian Serbs. In 1999, after pro�  independence insurgents began killing Serbian police and politicians, he  retaliated with ruthless attacks on the province (see Kosovo conflict).  NATO responded with a massive bombing campaign of Serbian targets.  The subsequent ethnic cleansing of the province by troops under  Milosevic�s command drove hundreds of thousands of Albanian Koso�  vars to other countries as refugees and earned him worldwide loathing as  a war criminal. In 2000 he was defeated in national elections. The fol�  lowing year he was arrested and extradited to The Netherlands to stand  trial for genocide, war crimes, and crimes against humanity. The trial  began in February 2002 but was frequently delayed because of  Milosevic�s poor health. On March 11, 2006, he was found dead in his  prison cell.</p><p>Milosz Vme-loshN, Czeslaw (b. June 30, 1911, Sateiniai, Lith., Rus�  sian Empire�d. Aug. 14, 2004, Krakow, Pol.) Polish-U.S. author, trans�  lator, and critic. Milosz was a socialist by the time he published his first  book of verse at age 21. During the Nazi occupation of Poland, he was  active in the resistance. After serving briefly as a diplomat for commu�  nist Poland, he immigrated to the U.S., where he taught for decades at the  University of California at Berkeley; he became a naturalized U.S. citi�  zen in 1970. His poetry, including such collections as Bells in Winter  (1978), is noted for its classical style and preoccupation with philosophi�  cal and political issues. His well-known essay collection The Captive  Mind (1953) condemned the accommodation of many Polish intellectu�  als to communism. U.S. critic Helen Vendler wrote that Milosz�s Trea�  tise on Poetry (1957) seemed to her �the most comprehensive and moving  poem� of the latter half of the 20th century. He was awarded the Nobel  Prize for Literature in 1980.</p><p>Milstein Vmil-.stln, 'mil-.stenV Cesar (b. Oct. 8, 1927, Bahia Blanca,  Arg.�d.

In 1975 Milstein and Georges  Kohler (1946-95) fused short-lived, highly specific lymphocytes with the  cells of a myeloma, a type of tumour that can reproduce indefinitely. The  hybrid cells, like lymphocytes, secreted antibody to a single antigen and,  like myeloma cells, perpetuated themselves. This enabled production of  large quantities of pure antibodies against single antigenic characteristics  (monoclonal antibodies). Milstein, Kohler, and Niels K. Jeme (1911-94)  shared the Nobel Prize in 1984.</p><p>Miltiades Vmil-'tl-o-.dezX the Younger (b. c. 554, Athens�d. prob�  ably 489 bc, Athens) Athenian general. He was sent by Hippias to  strengthen Athenian control of the sea routes from the Black Sea and made  himself a petty tyrant there. He fought the Scythians with Darius I in 513  and supported the Persians until the Ionian revolt (499-494). When the  revolt failed, he fled to Athens and led the Athenian army to victory at  the Battle of Marathon (490). He was put on trial and fined the next year  for a failed naval expedition meant to punish Paros for collaborating with  Persia; he died in prison soon after from a gangrenous wound.</p><p>Milton, John (b. Dec. 9, 1608, London, Eng.�d. Nov. 8, 1674, Chal-  font St. Giles, Buckinghamshire) English poet. A brilliant youth, Milton  attended Cambridge University (1625-32), where he wrote poems in  Latin, Italian, and English; these included �L�Allegro� and �II Penseroso�,  both published later in Poems (1645). During 1632-38 he engaged in pri�  vate study�writing the masque Comus (1637) and the extraordinary  elegy �Lycidas� (1638)�and toured Italy. Concerned with the Puritan  cause in England, he spent much of 1641-60 pamphleteering for civil and  religious liberty and serving in Oliver Cromwell�s government. His best-  known prose is in the pamphlets Areopagitica (1644), on freedom of the  press, and Of Education (1644). He lost his sight c. 1651, and thereafter  dictated his works. His disastrous first marriage ended with his wife�s  death in 1652; two later marriages were more successful. After the Res�  toration he was arrested as a noted defender of the Commonwealth but  was soon released. In Paradise Lost (1667), his epic masterpiece on the  Fall of Man written in blank verse, he uses his sublime �grand style� with  superb power; his characterization of Satan is a supreme achievement. He  further expressed his purified faith in God and the regenerative strength  of the individual soul in Paradise Regained (1671), an epic in which  Christ overcomes Satan the tempter, and Samson Agonistes (1671), a  tragedy in which the Old Testament figure conquers self-pity and despair  to become God�s champion. Considered second only to William Shakes�  peare in the history of English-language poetry, Milton had an immense  influence on later literature; though attacked early in the 20th century, he  had regained his place in the Western canon by mid century.</p><p>Milwaukee City (pop., 2000: 596,974) and lake port, southeastern  Wisconsin, U.S. The state�s largest city, it is situated on Lake Michigan.  Visited by French missionaries and fur traders in the 17th century, it was  called Mahn-a-waukee Seepe (�Gathering Place by the River�) by local  Indians. Although settled in 1800, the town did not develop until the Indi�  ans relinquished their claims in 1831-33. Milwaukee was formed in 1839  and incorporated in 1846. It was a centre of German immigration until c.  1900. It is a major Great Lakes port, shipping especially grain; it also pro�  duces electrical machinery. It has several educational institutions, includ�  ing Marquette University and the University of Wisconsin-Milwaukee.</p><p>Milyukov \m y il-yu-'k6f\, Pavel (Nikolayevich) (b.

A liberal who admired the political values of democratic countries, he  cofounded the progressive Constitutional Democratic Party in 1905 and led  the party in the Duma (1907-17). In 1917 he helped form the provisional  government under Prince Georgy Y. Lvov and served briefly as minister  of foreign affairs. He tried to form a moderate coalition against the Bol�  sheviks but was forced to leave Russia and eventually settled in Paris.</p><p>Mimamsa \me-'mam-sa\ Probably the earliest of the six orthodox sys�  tems (darshans) of Indian philosophy. Mimamsa is fundamental to  Vedanta and has deeply influenced Hindu law. Its aim is to give rules for  the interpretation of the Vedas and to provide a philosophical justification  for the observance of Vedic ritual. The earliest work of the system, the  Mimamsa-sutra of Jaimini (c. 4th century bc), was followed by the writ�  ings of a long line of interpreters and teachers, notably Kumarila Bhatta  and Prabhakara Mishra (8th century). Kumarila is credited with using  Mimamsa to defeat Buddhism in India; Prabhakara was a realist who  believed that sense perceptions were true.</p><p>Mimana See Kaya</p><p>mime and pantomime Dramatic performance in which a story is  told solely by expressive body  movement. Mime appeared in  Greece in the 5th century bc as a  comic entertainment that stressed  mimetic action but included song  and spoken dialogue. A separate  Roman form developed from c. 100  bc and centred on crude and licen�  tious subjects. Roman pantomime  differed from Roman mime by its  loftier themes and its use of masks,  which called for expression through  posture and hand gestures. Mime  was also important in Asian drama  from ancient times, and it is an ele�  ment in major Chinese and Japanese  dramatic forms (e.g., no theatre). The  Roman tradition of pantomime was  modified in the 16th-century comme-  dia dell'arte, which in turn influenced  the 18th-century French and English  comic interludes that developed into  19th-century pantomime, a chil�  dren�s entertainment emphasizing  spectacle. Modern Western mime  developed into a purely silent art in  which meanings are conveyed  through gesture, movement, and  expression. Famous mimes include  Jean-Gaspard Deburau, Etienne  Decroux (who developed a system�  atic language of gesture), and Mar�  cel Marceau. Charlie Chaplin was an accomplished mime, as were Sid  Caesar and the circus clown Emmett Kelly.</p><p>mimicry Similarity between organisms that confers a survival advan�  tage on one. In Batesian mimicry, an organism lacking defenses mimics  a species that does have defenses. In Mullerian mimicry, all species in a  group are similar even though all individually have defenses. In aggres�  sive mimicry, a predatory species mimics a benign species so that it can  approach its prey without alarming it, or a parasitic species mimics its  host. Some plant species mimic the colour patterns and scents of animals  for the purposes of pollination and dispersal. Mimicry differs from cam�  ouflage in that camouflage hides the organism, whereas mimicry benefits  the organism only if the organism is detected.</p><p>Mimir Vme-mir\ In Norse mythology, the wisest of the gods of the tribe  Aesir. He was also believed to be a water spirit. Mimir was sent by the  Aesir as a hostage to the rival gods (the Vanir), but he was decapitated  and his head was returned to the Aesir. Odin preserved the head in herbs  and gained knowledge from it. Other tales claim that Mimir lived by a  well beneath the roots of Yggdrasill, the world tree, and that he was a  smith who taught the hero Siegfried his craft.</p><p>mimosa Vmo-'mo-soV Any member of the more than 450 species that  make up the genus Mimosa in the family Mimosaceae, native to tropical  and subtropical areas throughout both hemispheres. Most are herbaceous  plants or undershrubs; some are woody climbers; a few are small trees.  They are often prickly. Mimosas are widely cultivated for the beauty of  their foliage and for their interesting response to light and mechanical  stimuli: the leaves of some species droop in response to darkness and close  up their leaflets when touched. The name comes from this �mimicking�  of animal sensibility. The roots of some species are poisonous; others  contain skin irritants. Many acacias are commonly but incorrectly called  mimosas. See also sensitive plant.</p><p>Min River River, central Fujian province, southeastern China. Rising in  the mountains near the Fujian-Jiangxi border, it flows southeast to empty  into the China Sea after a course of 358 mi (577 km). The arrival of a  railway system in 1957 increased its use for navigation, and there are  transshipment points along it.</p><p>Min River River, Sichuan province, south-central China. Rising in the  Min Mountains of northern Sichuan, it flows southward along the west�  ern side of the Sichuan Basin and empties into the Yangtze River (Chang  Jiang) at Yibin. It is navigable for most of its 350-mi (560-km) course.</p><p>Minamata disease X.mi-no-'ma-toV Disease first identified in 1956 in  Minamata, Japan. A fishing port, Minamata was also the home of Nippon  Chisso Hiryo Co., a manufacturer of chemical fertilizer, carbide, and vinyl  chloride. Methyl mercury discharged from the factory contaminated fish  and shellfish, which in turn caused illness in the local inhabitants who  consumed them and birth defects in their children. The sometimes fatal  disease was the first whose cause was recognized as industrial pollution  of seawater. It aroused worldwide concern and stimulated the develop�  ment of the environmental movement.</p><p>Minamoto Yoritomo \ 1 me-na- , mo-t6- l y6-re- , t6-mo\ (b. 1147,</p><p>Japan�d. Feb. 9, 1199, Kamakura) Founder of the Kamakura shogunate,  or bakufu. A member of the Minamoto warrior clan, Yoritomo was banished  in his youth as a consequence of his father�s revolt against the reigning  Taira family. In exile Yoritomo found support for his cause in Hojo Toki-  masa (see Hojo family), and in 1185 he defeated the Taira. In 1192 the clois�  tered emperor (see insei) granted him the title of shogun, which made him  the supreme authority over all military forces in the country. He established  his own governors ( shugo) and stewards ( jito ) throughout Japan, thereby  creating a governmental infrastructure in competition with, and gradually  superseding, that of the imperial court. He was thus able to rule without  actually overthrowing the emperor, a pattern that was to be emulated by  future shogunates. See also Kamakura period; Gempei War.</p><p>Minamoto Yoshitsune N.me-na-'mo-to-.yo-shet-'sun-aV (b. 1159,  Japan�d. June 15, 1189, Fort Koromogawa, Mutsu province, Japan)  Charismatic half brother of Minamoto Yoritomo who helped bring him  victory against the Taira family (see Taira Kiyomori). He was raised in a  monastery but ran away at 15 to join Yoritomo. On Yoritomo�s orders,  Yoshitsune seized Kyoto and then attacked and defeated the remaining  Taira forces along Japan�s Inland Sea. Yoritomo became jealous of Yoshit�  sune and, though Yoshitsune eluded him for several years, eventually was  able to have him killed. The Japanese have long considered Yoshitsune  to be the epitome of the underdog hero; many legends, stories, kabuki  plays, and even films celebrate his adventures with his faithful follower,  the monk Benkei.

Traditionally, the wife remained with her maternal  relatives after marriage; her husband continued to live with his mother  but visited his wife. The domestic unit, a community house, held a head  woman, her sisters, their daughters, and their children and visiting hus�  bands. Today that kinship structure has declined, and more men have left  their villages to establish their own households with wives and children.  Traditional Minangkabau are farmers, and their crafts include wood carv�  ing, metalwork, and weaving. Some migrated to Malaya (Peninsular  Malaysia) in the 1850s to participate in the rapid expansion of Malayan  tin mining; over time immigrants switched to farming, and in the 20th  century they came to control most of Malaya�s retail trade. The Minang�  kabau number two to five million.</p><p>Minas Basin Vml-nosV Eastern inlet of the Bay of Fundy, into central  Nova Scotia.

It is distinguished from empirical studies of the mind (e.g., psychology,  biology, physiology, sociology, and anthropology) by its method, which  emphasizes the analysis and clarification of concepts. See also cognitive  SCIENCE.</p><p>mind-body problem Metaphysical problem of the relationship  between mind and body. The modern problem stems from the thought of  Rene Descartes, who is responsible for the classical formulation of dual�  ism. Descartes�s interactionism had many critics even in his own day. Tho�  mas Hobbes denied the existence of mental substance. Materialism of a sort  was also supported by Descartes�s correspondent Pierre Gassendi (1592-  1655). Benedict de Spinoza posited a single substance of which the mental  and the material are attributes; his theory is known as psycho-physical  parallelism. More recent views include the double-aspect theory, identity  theory, eliminative materialism (which denies the reality of the familiar  categories of mental state posited in so-called folk psychology), and theo�  ries Of SUPERVENIENCE.</p><p>Mindanao V.min-do-'na-.o, .min-do-'nauV Island (pop., 2000:  16,136,921), southern Philippines. The second largest island in the Phil�  ippines, it has an area of 36,537 sq mi (94,630 sq km); it is 324 mi (521  km) long and 293 mi (471 km) wide. It is mountainous and contains active  volcanoes, including Mount Apo, the highest peak in the Philippines. The  rare monkey-eating eagle is unique to the island. Islam spread through�  out Mindanao in the 16th century. It was visited by Ferdinand Magellan  in 1521. It was later claimed by Spain, but the resistance of its Muslim  inhabitants kept it largely independent of Spanish authority. The autono�  mous region of Muslim Mindanao, in the western and southwestern por�  tions of the island, was created in 1990.</p><p>Mindanao River formerly Cotabato River \,ko-ta-'ba-to\ Main  river of central Mindanao, Philippines.

He was unable to persuade the Brit�  ish to return Pegu (in southern Myanmar) and was also forced to make  large economic concessions. Domestically, his reign was a time of numer�  ous reforms and great cultural and religious flowering. In 1857 he built  the new capital, Mandalay, with palaces and monasteries that are master�  pieces of traditional Myanmar architecture. He held the Fifth Buddhist  Council there in 1871 in an effort to revise and purify the Pali scriptures.</p><p>Mindoro Island (pop., 2000: 1,062,068), west-central Philippines.

He was appointed  primate of Hungary in 1945 and made a cardinal in 1946. Refusing to  permit Hungary�s Roman Catholic schools to be secularized by the com�  munists, he was arrested in 1948 and convicted of treason the next year.  Sentenced to life imprisonment, he was freed in the Hungarian Revolu�  tion (1956). When the communists regained control, he sought asylum in  the U.S. embassy in Budapest and lived there for 15 years, refusing Vat�</p><p>ican requests to leave Hungary. He relented in 1971, settled in Vienna,  and was retired as primate of Hungary in 1974.</p><p>mine See land mine, submarine mine</p><p>Miner, Jack orig. John Thomas Miner (b.

After moving to Canada in 1878, he established a bird sanc�  tuary in 1904 on his farm in Kingsville, Ont. Banding more than 50,000  ducks between 1910 and 1915, he made the first complete banding records  of North American birds. In 1931 his friends established the Jack Miner  Migratory Bird Foundation to ensure the continuation of his work. He  received the Order of the British Empire in 1943.</p><p>mineral Any naturally occurring homogeneous solid that has a definite  (but not fixed) chemical composition and a distinctive internal crystal  structure. Minerals are usually formed by inorganic processes. Synthetic  equivalents of various minerals, such as emeralds and diamonds, are  manufactured for commercial purposes. Although most minerals are  chemical compounds, a small number (e.g., sulfur, copper, gold) are ele�  ments. Minerals combine with each other to form rocks. For example,  granite consists of the minerals feldspar, quartz, mica, and amphibole in  varying amounts. Rocks are generally, therefore, an intergrowth of vari�  ous minerals.</p><p>mineral processing or ore dressing Mechanical treatment of  crude ores to separate the valuable minerals. Mineral processing was at  first applied only to ores of precious metals but later came to be used to  recover other metals and nonmetallic minerals. It is also used during coal  preparation to enrich the value of raw coal. The primary operations are  comminution and concentration. Comminution is carried out by large jaw  crushers and by smaller cylindrical grinding mills. Common methods of  concentration are gravity separation and flotation separation. Gravity  methods include jigging (ground ore is fed into a pulsating body of water  so that the heavier mineral fractions settle out, leaving lighter wastes at  the top) or washing the ore down inclined planes, spirals, or shaking tables  so that mineral and waste fractions settle in different areas. See also ben�  efication; MINING.</p><p>mineralogy Scientific study of minerals, including their physical prop�  erties, chemical composition, internal crystal structure, occurrence and  distribution in nature, and origins or conditions of formation. Mineralogic  studies range from description and classification of new or rare minerals  to analysis of crystal structure and laboratory or industrial synthesis of  mineral species. The methods employed include physical and chemical  identification tests, determination of crystal symmetry and structure, opti�  cal examination, X-ray diffraction, and isotope analysis.</p><p>Minerva In Roman reugion, the goddess of handicrafts, the professions,  the arts, and, later, war. She was commonly identified with the Greek  Athena. Some scholars believe that worship of Minerva began when Ath�  ena� s cult was introduced at Rome from Etruria. Minerva was one of the  Capitoline triad, along with Jupiter and Juno, and her shrine in Rome was  a meeting place for craftsmen�s guilds. The worship of Minerva attained  its greatest vogue under the emperor Domitian, who claimed her special  protection.</p><p>minesweeper Naval vessel used to clear submarine mines from an  expanse of water. In naval warfare, they are used to clear mines from sea-  lanes to protect merchant shipping as well as to clear paths for warships  to engage in battle or amphibious warfare. The earliest examples used  sweeping wires with sawlike projections to cut the cables anchoring sub�  marine mines and allow them to rise to the surface, where they would be  destroyed by gunfire. The wide use of magnetic mines (set off by the  magnetic field of steel ships) in the Korean War led to wood-hulled mine�  sweepers.</p><p>Ming dynasty (1368-1644) Chinese dynasty that provided an interval  of native rule between eras of Mongol and Manchu dominance. The Ming,  one of the most stable but autocratic of dynasties, extended Chinese influ�  ence farther than did any other native rulers of China. Under the Ming,  the capital of China was moved from Nanjing to Beijing, and the Forbid�  den City was constructed. Naval expeditions led by Zheng He paved the  way for trade with Southeast Asia, India, and eastern Africa. During the  Ming dynasty, novels were written in the vernacular, while philosophy  benefited from the work of Wang Yangming in Neo-Confucianism. Ming  monochrome porcelain became famous throughout the world, with imi�  tations created in Vietnam, Japan, and Europe.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Minggantu &#x25BA; minnesinger I 1263</p><p>Minggantu Chinese Ming Antu, Mongolian Minganto (b. ?�d.</p><p>c. 1763) Chinese astronomer and mathematician.

He spent his whole career there, at a time when Jesuit mission�  aries were in charge of calendar reforms. He took part in the compilation  of the imperially commissioned Liili yuanyuan (c. 1723; �Source of Math�  ematical Harmonics and Astronomy�), and from 1737 to 1742 he worked  with the Jesuits on the revision of its astronomical section. In 1759 he  became director of the Imperial Astronomical Bureau. He left an unfin�  ished mathematical manuscript, the Geyuan milii jiefa (�Quick Methods  for the Circle�s Division and Precise Ratio�), which his student Chen Jixin  completed in 1774.</p><p>Mingus, Charles (b.

Mingus played in the groups of Lionel Hampton, Duke Ellington, and Red  Norvo, ultimately working with many of the innovators of bebop. In 1953  he organized the Jazz Workshop ensemble, which played a spirited com�  bination of loosely arranged passages and improvisation, incorporating  elements of the blues and free jazz. As a pioneering bandleader and vir�  tuoso bassist, Mingus remained an uncompromising and innovative force  in jazz for the rest of his career. He was one of the most important and  colourful figures in modem jazz.</p><p>Min how See Fuzhou</p><p>miniature painting Small, detailed painting, usually a portrait,  executed in watercolour on vellum (parchment), prepared card, copper, or  ivory that can be held in the hand or worn as a piece of jewelry. The name  derives from the minium, or red lead, used to emphasize initial letters in  medieval illuminated manuscripts. Combining the traditions of illumina�  tion and the Renaissance medal, it flourished from the early 16th to the  mid-19th century. The earliest datable examples were painted in France  by Jean Clouet the Younger at the court of Francis I; in England H. Hol�  bein the Younger produced masterpieces in miniature under Henry VIII and  inspired a long tradition of the practice, known as �limning.� Nicholas  Hilliard served as miniature painter to Elizabeth I for more than 30 years.  In the 17th�18th centuries, painting in enamel on metal became popular  in France. In Italy Rosalba Carriera introduced the use of ivory (c. 1700)  as a luminous surface for transparent pigments, stimulating a great revival  of the medium in the late 18th century. By the mid-19th century minia�  ture paintings were regarded as luxury items and rendered obsolete by the  new medium of photography.</p><p>Minimalism Twentieth-century movements in art and music character�  ized by extreme simplicity of form and rejection of emotional content. In  the visual arts, Minimalism originated in New York City in the 1950s as  a form of abstract art and became a major trend in the 1960s and �70s.  The Minimalists believed that a work of art should be entirely self-  referential; personal elements were stripped away to reveal the objective,  purely visual elements. Leading Minimalist sculptors include Carl Andre  and Donald Judd; Minimalist painters include Ellsworth Kelly and Agnes  Martin. In music, Minimalism arose in the 1960s. It employs a steady  pulsing beat, incessant repetition of tones and chords with only gradual  changes in their components, a slow rate of harmonic change, and little  or no counterpoint. Its principal antecedents are the musics of India and  Southeast Asia. Its most important early practitioners include La Monte  Young (b. 1935), Terry Riley (b. 1935), whose In C (1964) is perhaps its  most seminal work, Steve Reich, Philip Glass, and John Adams.</p><p>minimum In mathematics, a point at which the value of a function is  lowest. If the value is less than or equal to all other function values, it is  an absolute minimum. If it is merely less than at any nearby point, it is a  relative, or local, minimum. In calculus, the derivative equals zero or does  not exist at a function�s minimum point. See also maximum, optimization.</p><p>minimum wage Wage rate established by collective bargaining or by  government regulation, specifying the lowest rate at which workers may  be employed. A legal minimum wage is one mandated by government for  all workers in an economy, with few exceptions. Privately negotiated  minimum wages determined by collective bargaining apply to a specific  group of workers in the economy, usually in specific trades or industries.  The modern minimum wage, combined with compulsory arbitration of  labour disputes, first appeared in Australia and New Zealand in the 1890s.  In 1909 Britain established trade boards to set minimum wage rates in  certain trades and industries. The first minimum wage in the U.S. (which</p><p>applied only to women) was enacted by Massachusetts in 1912. Mini�  mum wage laws or agreements now exist in most nations.</p><p>mining Excavation of materials from the Earth�s crust, including those  of organic origin, such as coal and petroleum. Modern mining is costly  and complicated. First, a mineral vein that can likely produce enough of  the desired substance to justify the cost of extraction must be located.  Then the size of the vein or deposit is determined, and mining engineers  decide the best way to mine it. Most of the world�s yearly mineral pro�  duction is extracted by surface mining, which includes open-pit mining,  strip mining, and quarrying. For ore bodies that lie a considerable dis�  tance below the surface, underground mining must be considered. In both  techniques, excavating and extracting mineral substances involve costly  combinations of drilling, blasting, hoisting, and hauling, as well as mea�  sures for health and safety and reduction of environmental impact.</p><p>mink Either of two species of nocturnal, semiaquatic carnivores in the  weasel family (Mustelidae) that are  trapped and raised commercially for  their pelts.

While researching diabetes mellitus in 1884,  he found that beta-hydroxybutyric acid and a decrease in blood bicarbon�  ate cause diabetic acidosis (low blood pH) and that diabetic coma is  accompanied by decreased blood carbon dioxide and can be treated by  alkali therapy. Experiments on dogs with Joseph von Mering (1849-1908)  led Minkowski to propose that the pancreas is the source of an �antidi�  abetic� substance, now known to be insulin. He also demonstrated that  the liver produces bile pigments and uric acid.</p><p>Minneapolis City (pop., 2000: 382,618), eastern Minnesota, U.S. The  state�s largest city, it is situated on the Mississippi River near the mouth of the  Minnesota River. With St. Paul across the river it forms the Twin Cities met�  ropolitan area. Visited by French missionary Louis Hennepin in 1680, the  area developed as a military outpost. On the eastern bank was the village of  St. Anthony (inc. 1855), on the western bank, Minneapolis village (inc.  1856). In 1872 the two merged as the city of Minneapolis, which developed  as a centre of the lumber and flour-milling industries. Still a grain market  for the surrounding agricultural region, it is also a manufacturing centre. Its  educational institutions include the University of Minnesota.</p><p>Minnelli, Vincente (b.

The most northerly of the 48 contiguous U.S. states, it has exten�  sive woodlands, fertile prairies, and numerous lakes. Before European  settlement, the region was inhabited by the Ojibwa (Chippewa) and the  Dakota (Sioux) tribes. French explorers arrived in search of the Northwest  Passage in the mid 17th century. The northeastern portion passed to the  British in 1763 and then to the U.S. in 1783, becoming part of the North�  west Territories in 1787. The southwestern portion was acquired by the  U.S. in 1803 as part of the Louisiana Purchase, and the northwestern por�  tion was ceded to the U.S. by the British by treaty in 1818. The first per�  manent U.S. settlement was made in 1819, when Fort Snelling was  founded. The Minnesota Territory, established in 1849, included present-  day Minnesota and the eastern sections of North and South Dakota. Min�  nesota became the 32nd U.S. state in 1858. The Sioux Uprising in  southern Minnesota in 1862 resulted in the death of 500 civilians, sol�  diers, and Indians. Commercial iron-ore production began in 1884, and  after the huge iron reserves of the Mesabi Range were discovered in 1890,  the population at Duluth and Superior grew rapidly.

The sea was the basis of their economy and power. Their sophisti�  cated culture, based at Knossos, was named for the legendary King Minos.  It represented the first high civilization in the Aegean area. The Minoans  exerted great influence on the Mycenaean culture of the Greek islands and  mainland. Minoan culture reached its peak c. 1600 bc and was noted for  its cities and palaces, extended trade contacts, and use of writing (see Lin�  ear A and Linear B). Its art included elaborate seals, pottery, and, notably,  the vibrant frescoes decorating palace walls, which depicted both religious  and secular scenes, including goddesses reflective of a matriarchal reli�  gion. Palace ruins show evidence of paved streets and piped water. Famil�  ial - Minoan art motifs are the snake (symbol of the goddess) and the bull  and leaping dancer, also of mystical significance.</p><p>Minos Vml-n3s\ In Greek legend, a king of Crete, the son of Zeus and  Europa. He gained the throne with the aid of Poseidon and also became  ruler of the Aegean islands. His wife Pasiphae fell in love with a bull and  gave birth to the Minotaur, which was imprisoned in the Labyrinth. Minos  waged war against Athens and exacted a tribute of youths and maidens  to feed the Minotaur until Theseus killed the monster with the aid of  Minos�s daughter Ariadne. Minos was killed in Sicily when boiling water  was poured over him as he was taking a bath.

He reversed anemia in dogs  (induced by excessive bleeding) with a diet of raw liver; subsequently he  and William Murphy (1894-1987) found that eating raw liver reversed  pernicious anemia in humans. They shared a Nobel Prize in 1934 with  George Whipple for their treatment of the previously invariably fatal dis�  ease. He and Edwin Joseph Cohn prepared liver extracts that, taken orally,  were the main treatment for pernicious anemia until 1948, when vitamin  B 12 was isolated.</p><p>Minotaur Vmi-no-.toA In Greek mythology, a monster of Crete with the  body of a man and the head of a bull.

When Minos kept it instead, the god punished him by making his  wife fall in love with the bull. The Minotaur (whose name means �Minos  bull�) was imprisoned in the Labyrinth built by Daedalus. After defeating  Athens in a war, Minos forced the Athenians to send human tribute to be  devoured by the Minotaur. The third year the tribute was sent, Theseus vol�  unteered to go, and with the help of Ariadne he killed the monster.</p><p>Minsk Capital (pop., 2001 est.: 1,699,000) and largest city of Belarus.

Blackfaced white minstrel troupes were  particularly popular in the U.S. and England in 1840-80 and included  groups such as the Christy Minstrels, who played on Broadway for 10  years and had songs composed for them by Stephen Foster. The minstrel  show included an opening chorus and frequent exchanges of jokes  between the emcee, Mr. Interlocutor, and the end men, Mr. Tambo (who  played the tambourine) and Mr. Bones (who rattled the bones), inter�  spersed with ballads, comic songs, and instrumental numbers (usually on  the banjo and violin), as well as individual acts, soft-shoe dances, and  specialty numbers. Minstrel troupes composed of African Americans were  formed after the Civil War; in general, minstrel shows were the only the�  atrical medium in which black performers of the period could support  themselves. Minstrel shows had effectively disappeared by the early 20th  century, but the effects of their racial stereotyping persisted in perfor�  mance mediums well into mid century.</p><p>mint' In botany, any strong-scented herb of the genus Mentha , composed  of about 25 species of perennial herbs, and certain related genera of the  mint family (Lamiaceae, or Labiatae), which contains about 3,500 spe�  cies of flowering plants in about 160 genera.

Small flowers usually pale purple, pink, or white, are arranged in clus�  ters, either forming separate whorls or crowded together in a terminal  spike. All Mentha species contain volatile oil in resinous dots in the leaves  and stems. Included in this genus are peppermint, spearmint, marjoram, rose�  mary, and thyme; other members of the mint family include lavender, hys�  sop, and catnip.</p><p>mint In economics, a place where coins are made according to exact  compositions, weights, and dimensions, usually specified by law. The first  state mint was probably established by the Lydians in the 7th century bc.  The art spread through the Aegean Islands into Italy and other Mediter�  ranean countries, as well as to Persia and India. The Romans laid the  foundations of modern minting standards. Coining originated indepen�  dently in China in the 7th century bc and spread to Japan and Korea. In  medieval Europe, mints proliferated as every feudal authority�kings,  counts, bishops, and free cities�exercised the mint privilege; the wide  variation in coinage that resulted often handicapped commerce. Most  countries now operate only one mint, though the U.S. has two active  mints, in Philadelphia and Denver. Proof sets of coins for coin collectors  are minted in San Francisco. Countries not large or prosperous enough to  establish a national mint have their coins struck in foreign mints. Many  mints perform functions other than minting, notably refining precious  metals and manufacturing medals and seals.

Using small, slow steps to music in 3 A time, dancers often performed  choreographed figures combined with stylized bows and curtsies. The  most popular dance of the 18th-century aristocracy, it fell from favour  after the French Revolution in 1789. It was of great importance in art  music; commonly incorporated into the suite c. 1650-1775, it was the only  dance form retained in the symphony, sonata, string quartet, and other  multimovement art-music genres up to c. 1800.</p><p>Minuit Vmin-yo-wotV Peter (b. c. 1589, Wesel, Kleve�d. June 1638,  Caribbean Sea) Dutch colonial governor of New Netherland. In 1626 the  Dutch West India Co. named him director general of the colony on Man�  hattan Island. According to legend, to legitimize Dutch occupation of the  island he persuaded the Indians to sell it for a handful of trinkets worth  about 60 guilders ($24). At the island�s southern tip he founded New  Amsterdam. He was recalled to Holland (1631) and later was sent to  establish the colony of New Sweden on Delaware Bay, where he again  purchased land from the Indians and built Fort Christina (later Wilming�  ton, Del.) in 1638.</p><p>minuscule Vmi-nos-.kyiil, mi-'nos-.kyulV Lowercase letters in calligra�  phy, in contrast to majuscule, or uppercase letters. Unlike majuscules,  minuscules are not fully contained between two real or hypothetical lines;  their stems can go above or below the line. Developed by Alcuin in the  8th century, it allowed the division of writing into sentences and para�  graphs by beginning sentences with capital letters and ending them with  periods. The script was originally rounded, but gradually the strokes  became heavier until it became what is now known as Gothic or black  letter script.</p><p>minuteman Colonial soldier of the American Revolution. Minutemen  were first organized in Massachusetts in September 1774, when revolu�  tionary leaders sought to eliminate Tories, or British sympathizers, from  the militia by replacing all officers. One-third of the members of each new  regiment was to be ready for military duty �at a minute�s warning.� Their  first great test took place at the Battles of Lexington and Concord. On July  18 the Continental Congress recommended that other colonies organize  minuteman units.</p><p>Minuteman missile U.S. ICBM first deployed in 1962. Its three  generations�the Minuteman I (1962-73), the Minuteman II (1966-95),  and the Minuteman III (from 1970)�have constituted most of the land-  based nuclear arsenal of the U.S. since the 1960s. They were the first U.S.  ICBMs to be based in underground silos, use solid fuel, and be fitted with  multiple independently targeted reentry vehicles (see MIRV). Under the  terms of the Strategic Arms Reduction Talks, the Minuteman II force was  dismantled and the Minuteman III scheduled for downgrading to a single  warhead.</p><p>Miocene Vml-o-.senX Epoch Major division of the Tertiary Period, from  23.8 to 5.3 million years ago.

Miocene mammals were essentially  modern, and half of the known modern families are present in the Miocene  record. The horse evolved, mainly in North America, and advanced pri�  mates, including apes, were present in southern Europe. Some interchange  of faunas occurred in the Northern Hemisphere between the Old and New  Worlds.

It consists of a core module launched in 1986  and five additional modules launched separately over the next decade and  attached to the core unit to create a large, versatile space laboratory. The  third generation of Russian space stations (see Salyut), Mir featured six  docking ports for modules and other spacecraft, expanded living quarters,  more power, and modernized research equipment. It supported human  habitation between 1986 and 2000, including an uninterrupted stretch of  occupancy of almost 10 years, and it hosted a series of U.S. astronauts in  1995-98 as part of a Mir-SPACE shuttle cooperative endeavour. In 1995,  Valery Polyakov (b. 1942) set a world endurance record of nearly 438  days in space aboard Mir. In March 2001 the abandoned station was  brought down in a controlled reentry, with the surviving pieces falling  into the Pacific Ocean.</p><p>MTr Sayyid �All (fl. 16th century) Persian miniature painter. Born in  Tabriz, he went to India about 1545. He and fellow countryman �Abd  al-Samad instructed the artists of the imperial atelier, most of them Indi�  ans, and thereby helped to found the school of Mughal painting. He super�  vised part of the production of the illustrations to the Mughal manuscript  Dastan-e Amir Hamzeh (�Stories of Amir Hamzeh�). The few paintings  by him that have survived reveal that he was a highly gifted painter,  wielding a delicate brushstroke and great powers of observation.</p><p>Mira Bai Vme-ra-'ba-eV (b. 1450?, Kudaki, India�d. 1547?, Dwarka,  Gujarat) Rajput princess and Hindu mystic whose songs are popular in  northern India. According to legend, Mirabai dedicated her life to Krishna  after her husband�s death. She received sadhus and pilgrims at her pri�  vate temple dedicated to Krishna and composed songs of devotion to him,  unorthodox pursuits for a widow. Her poems allude to two attempts on  her life, both foiled miraculously. When a delegation of Brahmans sought  to return her to her husband�s kingdom, she disappeared. Only two poems  bearing her signature can be dated before the 18th century, but her story  is the most familiar among those of northern Indian saints.</p><p>Mirabeau \me-ra-'bo\, Honore-Gabriel Riqueti, count de orig.  Honore-Gabriel Riqueti (b. March 9, 1749, Bignon, near Nemours,  France�d. April 2, 1791, Paris) French politician and orator. Son of the  economist Victor Riqueti (1715-89), he suffered his father�s disfavour;  often imprisoned for intrigues and wild behaviour (1774-80), he wrote  several essays on prison life. In 1789 he was elected to the Estates Gen�  eral from the Third Estate. A skilled orator, he was popular with the people  and was influential in the early years of the French Revolution. He advo�  cated a constitutional monarchy and tried to mediate between the abso�  lute monarchists and the revolutionaries. He was elected president of the  National Assembly in 1791, but he died shortly thereafter.</p><p>Mirabello, Gulf of Gulf of the Aegean Sea on the northern coast of  Crete, Greece.

Belief  in miracles exists in all cultures and nearly all religions. The Upanishads  assert that the experience of religious insight and transformation is the  only �miracle� worth considering, but popular Hinduism attributes miracu�  lous powers to the ascetic yogis. Confucianism had little room for miracles.  Daoism, however, mingled with Chinese folk religion to produce a rich  crop of miracles. Though Buddha Gautama deprecated his own miracu�  lous powers as devoid of spiritual significance, accounts of his miracu�  lous birth and life were later woven into his legend and into those of later  Buddhist saints. Miracles are taken for granted throughout the Hebrew  scriptures and were fairly common in the Greco-Roman world. The New  Testament records miracles of healing and other wonders performed by  Jesus. Miracles also attest to the holiness of Christian saints. Muhammad  renounced miracles as a matter of principle (the Qur�an was the great</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1266 I miracle play &#x25BA; Mishima</p><p>L_</p><p>N</p><p>miracle), but his life was later invested with miraculous details. Muslim  popular religion, particularly under the influence of Sufism, abounds in  miracles and wonder-working saints.</p><p>miracle play Type of vernacular drama performed in the Middle Ages,  presenting a real or fictitious account of the life, miracles, or martyrdom  of a saint. The genre evolved from the liturgical dramas of the 10th- 11th  centuries, which were intended to enhance church calendar festivals. By  the 13th century the plays were separated from church services and per�  formed at public festivals by members of craft guilds and other amateur  actors. Most miracle plays concerned either the Virgin Mary or St. Nicho�  las, both of whom had active cults in the Middle Ages. See also morality  play; mystery play.</p><p>mirage \m3-'razh\ In optics, the deceptive appearance of a distant object  caused by the bending of light rays (refraction) in layers of air of vary�  ing density. Under certain conditions, such as over a stretch of pavement  or desert air heated by intense sunshine, the air cools rapidly with eleva�  tion and therefore increases in density and refractive power. Sunlight  reflected down from the upper portion of an object will be directed  through the cool air in the normal way; although the light would not be  seen ordinarily because of the angle, it curves upward after it enters the  rarefied hot air near the ground, thus being refracted to the observer�s eye  as though it had originated below the heated surface. When the sky is the  object of the mirage, the land is mistaken for a lake or sheet of water.</p><p>mi'raj \'mi-raj\ In Islamic tradition, the ascension of Muhammad into  heaven. One night, according to the tradition, Muhammad was visited by  two archangels, who opened his body and purified his heart of all doubt,  error, and paganism. He was carried to heaven, where he ascended the  seven levels to reach the throne of God. Along the way he and the arch�  angel JibrTl met the prophets Adam, Yahya (John the Apostle), ( Isa (Jesus),  Yusuf (Joseph), Idris, Harun (Aaron), Musa (Moses), and Ibrahim (Abra�  ham) and visited hell and paradise. He learned that he was more highly  regarded by God than all the other prophets.

In the 1930s she was the  most popular recording artist in Brazil, where she appeared in five films.  Recruited by a Broadway producer, she starred in The Streets of Paris  (1939), then made her U.S. film debut in Down Argentine Way (1940).  Typecast as the �Brazilian Bombshell� and given such caricatural roles  as �The Lady in the Tutti-Frutti Hat� in The Gang�s All Here (1943), she  became the highest-paid female performer in the U.S. during World War  II.

He joined the Span�  ish army but fled to the U.S. in 1783, where he met leaders of the Ameri�  can Revolution and formed plans for the liberation of South America,  which he envisioned ruled by an Incan emperor and a bicameral legisla�  ture. He launched an unsuccessful invasion of Venezuela in 1806 and  returned at the request of Simon Bolivar to fight again in 1810. He assumed  dictatorial powers in 1811 when independence was declared but suc�  cumbed to a Spanish counterattack and signed an armistice. Fellow revo�  lutionaries, viewing his surrender as traitorous, thwarted his attempt to  escape. He died in a Spanish prison cell.</p><p>Miranda v. Arizona (1966) U.S. Supreme Court decision that speci�  fied a code of conduct for police during interrogations of criminal sus�  pects. Miranda established that the police are required to inform arrested  persons that they have the right to remain silent, that anything they say  may be used against them, and that they have the right to an attorney. The  case involved a claim by the plaintiff that the state of Arizona, by obtain�  ing a confession from him without having informed him of his right to  have a lawyer present, had violated his rights under the Fifth Amendment  regarding self-incrimination. The 5-to-4 decision shocked the law-  enforcement community; several later decisions limited the scope of the  Miranda safeguards.

He attended a com�  mercial school and worked as an  office clerk until a mental breakdown  persuaded his artisan father to permit  him to study art. From the beginning  he sought to express concepts of  nature metaphorically. From 1919 on  he lived alternately in Spain and  Paris, where he came under the influ�  ence of Dadaism and Surrealism. The  influence of Paul Klee is apparent in  his �dream pictures� and �imaginary  landscapes� of the late 1920s, in  which linear configurations and  patches of colour look almost as  though they had been set down ran�  domly. His mature style evolved  from the tension between this fanci�  ful, poetic impulse and his vision of  the harshness of modern life. He  worked extensively in lithography  and produced numerous murals, tapestries, and sculptures for public  spaces.</p><p>MIRV \'marv\ in full multiple independently targeted reentry  vehicle Any of several nuclear warheads carried on the front end of a  ballistic missile. The technique allows separately targeted nuclear war�  heads to be released from the missile on different trajectories, thus attack�  ing several targets from only one launcher. MIRVed ballistic missiles were  first deployed by the U.S. and then the Soviet Union in the 1970s, fol�  lowed by Britain and France in the 1980s and possibly China in the 1990s.  Because multiple warheads represent a significant increase in firepower,  they have often been an issue in arms control negotations. The Strategic  Arms Reduction Talks commit both the U.S. and Russia to limit the num�  ber of MIRVs on some missiles.</p><p>miscarriage or spontaneous abortion Spontaneous expulsion of  an embryo or fetus from the uterus before it can live outside the mother.  More than 60% are caused by an inherited defect in the fetus, which might  result in a fatal abnormality. Other causes may include acute infectious  disease, especially if it reduces the fetus�s oxygen supply; abnormalities  of the uterus that have physical or hormonal origins; and death of the fetus  from umbilical-cord knotting. The main sign of impending miscarriage is  vaginal bleeding.</p><p>misdemeanour See felony and misdemeanour</p><p>Mises Vme-zes\, Ludwig (Edler) von (b. Sept. 29, 1881, Lemberg,  Austria-Hungary�d.

He taught at the University of Vienna (1913-38) before immi�  grating to the U.S. and joining the New York University faculty (1945�  69). In The Anti-Capitalistic Mentality (1956), an examination of U.S.  socialism, he dealt with the opposition to the free market by intellectu�  als, who, in his view, bear an unwarranted resentment toward mass  demand, which is the basis of prosperity in big business.</p><p>Mishima \'me-she-ma\ Yukio orig. Hiraoka Kimitake (b. Jan. 14,  1925, Tokyo, Japan�d. Nov. 25, 1970, Tokyo) Japanese writer. Having  failed to qualify physically for military service in World War II, Mishima  worked in a Tokyo factory and after the war studied law. He won acclaim  with his first novel. Confessions of a Mask (1949). Many of his charac�  ters are obsessed with unattainable ideals and erotic desires, as in The  Temple of the Golden Pavilion (1956). His epic The Sea of Fertility, 4  vol. (1965-70), is perhaps his most lasting achievement. He strongly  opposed Japan�s close ties to the West in the postwar era (notably the new  constitution that forbade rearmament) and yearned to preserve Japan�s  martial spirit and reverence for the emperor. In a symbolic gesture of these  beliefs, he died by committing seppuku (ritual disembowelment) after seiz�  ing a military headquarters. He is often considered one of Japan�s most  important 20th-century novelists.</p><p>Joan Miro, photograph by Yousuf  Karsh, 1966.</p><p>KARSH/WOODFIN CAMP AND ASSOCIATES</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Mishna &#x25BA; Mississippi I 1267</p><p>Mishna or Mishnah \mesh-'na, 'mish-noN Oldest authoritative collec�  tion of Jewish oral law, supplementing the written laws in the Hebrew  Scriptures.

Missiles vary from small tactical  weapons effective out to only a few hundred feet to much larger strategic  weapons with ranges of several thousand miles. They were not developed  in any significant way until after World War II. Almost all contain some  form of guidance and control mechanism and are therefore often called  guided missiles. An unguided military missile, as well as any launch vehicle  used to penetrate the upper atmosphere or place a satellite in space, is  usually called a rocket. A propeller-driven underwater missile is called a  torpedo, and a guided missile powered along a low, level flight path by  an air-breathing jet engine is called a cruise missile.

The advance of  Christianity slowed with the disintegration of the Roman Empire after ad  500 and the growth of Arab power in the 7th-8th century, but Irish and  Anglo-Saxon missionaries continued to spread the faith in western and  northern Europe, while missionaries of the Greek church in Constantino�  ple worked in eastern Europe and Russia. Missions to Islamic areas and  Asia began in the medieval period, and when Spain, Portugal, and France  established overseas empires in the 16th century, the Roman Catholic  church sent missionaries to the Americas and the Philippines. A renewed  wave of Roman Catholic missionary work in the 19th century focused on  Africa and Asia. Protestant churches were slower to undertake foreign  missions, but in the 19th and early 20th century there was a great upsurge  in Protestant missionary activity.

It covers 47,695 sq mi (123,530 sq km); its capital is Jackson.  Its landscape ranges from hills and pine woods to plains and river low�  lands. Before European settlement, the area was inhabited by several  Indian tribes, including the Choctaw, Natchez, and Chickasaw. It became  part of French-controlled Louisiana, and Biloxi was settled in 1699. The  northern portion was ceded to the U.S. in 1783; the southern portion was  included in the Mississippi Territory (created 1798), which expanded in  1804 to include most of the present-day state. Mississippi became the 20th  U.S. state in 1817. A plantation-based economy using slave labour devel�  oped in the 1820s. It seceded from the Union in 1861 and gave the Con�  federacy its president, Jefferson Davis. The Union capture of Vicksburg in  1863 proved a turning point in the American Civil War.

It enters  the Gulf southeast of New Orleans, after a course of 2,350 mi (3,780 km).  It is the largest river in North America, and with its tributaries it drains an  area of 1.2 million sq mi (3.1 million sq km). Spanish explorer Hernando  de Soto was the first European to discover the river in 1541. French explor�  ers Louis Jolliet and Jacques Marquette traveled down it in 1673 as far as the  Arkansas River. French explorer La Salle reached the delta in 1682 and  claimed the entire Mississippi region for France, as Louisiana. France kept  control over the upper river, but the lower portion passed to Spain in 1769.  It was designated the western boundary of the U.S. in 1783. France sold it  to the U.S. in 1803 as part of the Louisiana Purchase. During the American  Civil War, Union forces captured Vicksburg, Miss., in 1863, breaking the  Confederate hold on the river. As the central river artery of the U.S., it is  one of the busiest commercial waterways in the world.</p><p>Mississippian culture Last major prehistoric cultural development  in North America, c. ad 800-1550. It spread over much of the southeast  and the mid-continent, especially in the major river valleys. It was based  on intensive cultivation of corn, beans, squash, and other crops. Each large  town dominated a group of satellite villages. Each had a central ceremo�  nial plaza with one or more pyramidal or oval earthen mounds surmounted  by a temple, a pattern indicating a connection to Central America. The  immense Cahokia Mounds near present-day Collinsville, Ill., U.S., was  the culture�s largest urban centre. Craftwork was executed in copper, shell,  stone, wood, and clay.

The Missouri River runs from west to east across the state. The area  north of it has rolling hills and fertile plains, the area south has deep valleys  and swift streams. The region was originally inhabited by various Indian  peoples, one of which, the Missouri, gave the state its name. The first per�  manent European settlement was made in 1735 at Ste. Genevieve by  French hunters and lead miners. St. Louis was founded in 1764. The U.S.  gained control of the region in 1803 as part of the Louisiana Purchase. It was  part of Louisiana Territory in 1805 and Missouri Territory in 1812. An  influx of U.S. settlers occurred after the War of 181 2. Missouri became the  24th state in 1821, but only after the Missouri Compromise allowed its admis�  sion as a slave state. It suffered much tension between slaveholders and  abolitionists, evidenced in the Dred Scott decision in 1857. Missouri  remained in the Union during the American Civil War, though its citizens  fought on both sides. After the war, its economic growth expanded and was  celebrated in the St. Louis Exhibition of 1904. After World War II, its  economy shifted from agriculture to manufacturing. It leads the nation in  lead production, based mainly in the Ozarks region.</p><p>Missouri Compromise (1820) Act passed by the U.S. Congress  admitting Missouri to the Union as the 24th state. After the territory  requested statehood without slavery restrictions, Northern congressmen  tried unsuccessfully to attach amendments restricting further slaveholding.  When Maine (originally part of Massachusetts) requested statehood, a  compromise led by Henry Clay allowed Missouri admission as a slave state  and Maine as a free state, with slavery prohibited from then on in territories  north of Missouri�s southern border. Clay�s compromise appeared to settle  the slavery-extension issue but highlighted the sectional division.</p><p>Missouri Plan Method of selecting judges that originated in the state  of Missouri and was later adopted elsewhere. Designed to overcome the  weaknesses of the elective system, the plan permits the governor to select  a judge from a list of nominees recommended by a special commission,  but requires that the judge be approved in a public referendum after serv�  ing a period of time.</p><p>Missouri River River, central U.S. The longest tributary of the Mississippi  River, it rises in the Rocky Mountains of southwestern Montana. It flows east  to central North Dakota and south across South Dakota, forming sections of  the South Dakota-Nebraska boundary, the Nebraska-Iowa boundary, the  Nebraska-Missouri boundary, and the Kansas-Missouri boundary. It then  meanders east across central Missouri to join the Mississippi River north of  St. Louis, after a total course of 2,315 mi (3,726 km). It has been nicknamed  �Big Muddy� because of the amount of silt that it carries. The first Euro�  peans to visit its mouth were French explorers Jacques Marquette and Louis  Jolliet in 1673. The first exploration of the river from its mouth to its head�  waters was made in 1 804�05 by the Lewis and Clark Expedition. Since the  mid 20th century, programs have been instituted along its banks to check its  turbulent flooding and to harness it for irrigation.</p><p>Missouri River, Little See Little Missouri River</p><p>Misti \'mes-te\ Volcano Spanish Volcan Misti Volcano, Andes  Mountains, southern Peru.

Strictly applied, the term  describes the duplication and distribution of chromosomes. Prior to mito�  sis, each chromosome is replicated, producing two strands (chromatids)  attached at a centromere. During mitosis, the membrane around the cell�s  nucleus dissolves and the chromatids of each chromosome are separated  and pulled to each end of the cell. As the nuclear membrane re-forms  around each set of chromosomes, the cytoplasm of the parent cell begins  to divide to form two daughter cells. Following mitosis, the cell mem�  brane pinches in to separate the daughter cells. Mitosis is essential to life  because it provides new cells for growth and for replacement of worn-out  cells. It may take minutes or hours, depending on the kind of cells and  species of organisms. It is influenced by time of day, temperature, and  chemicals.

A. Prophase. Replicated chromosomes, consisting of two daugh�  ter strands (chromatids) attached by a centromere, coil and contract. Two pairs of  specialized organelles (centrioles) begin to move apart, forming a bridge of hollow  protein cylinders known as microtubules (spindle fibres) between them. Microtu�  bules also extend in a radial array (aster) from the centrioles to the poles of the cell.  B. Late prophase. As the centrioles move apart, the nuclear membrane breaks  down and microtubules extend from each centromere to opposite sides or poles of  the cell. C. Metaphase. The centromeres align in a plane midway between the poles  known as the equator, or metaphase plate. During late metaphase, each cen�  tromere divides into two, freeing sister chromatids from each other. D. Anaphase.  Sister chromatids are drawn to opposite ends as centromeric microtubules shorten  and polar microtubules lengthen, causing the poles to move farther apart. E. Telo�  phase. Chromosomes uncoil, microtubules disappear, and the nuclear membrane  re-forms around each set of daughter chromosomes.

March 12, 1851, Edo) Chief adviser to the 12th  Tokugawa shogun, Tokugawa Ieyoshi (r. 1837-53). In the face of social  and economic decline, Mizuno tried to implement a series of reforms that  would return late Tokugawa-period Japan to the martial simplicity of the  early days of the shogunate. He enacted sumptuary laws, canceled samu�  rai debts, decreed a price and wage cut, and tried to force unauthorized  peasant migrants to leave the cities and return to the countryside. These  so-called Tempo Reforms failed, and Mizuno was removed from office.</p><p>Mjollnir Vmycel-nir, 'myol-nir\ In Norse myth, the hammer of Thor and  the symbol of his power. Forged by dwarfs, the hammer never failed Thor  as a weapon or as an instrument of sanctification. It had many magical  qualities, including the ability to return to Thor�s hand after it had been  thrown. It was stolen by the giant Thrym, who asked as ransom the hand  of Freyja. When Freyja refused to go to Thrym, Thor, masquerading as  Freyja, managed to seize the hammer, which had been brought out to con�  secrate Freyja as Thrym�s bride, and slaughtered Thrym and the other  giants.</p><p>Mjosa Vmce-sa\, Lake Lake, southeastern Norway.

Species ranged from turkey-sized to 10 ft (3  m) high. Moas were swift runners that defended themselves by kicking.  They were hunted for their flesh (eaten as food), bones (used as weapons  and ornaments), and eggs (used for water vessels). The larger moas were  probably extinct by the late 17th century; a few smaller species may have  survived into the 19th century. Moas browsed and grazed on seeds, fruits,  leaves, and grasses. They laid a single large egg in a hollow in the ground.</p><p>Moab \'mo-,ab\ Kingdom, ancient Palestine. Located east of the Dead  Sea in what is now southwestern Jordan, it was bounded by Edom and the  land of the Amorites. The Moabites were closely related to the Israelites  but were sometimes at war with them and sometimes allied to them. The  Moabite Stone, found at Dibon, recorded the 9th-century-BC victories of  the Moab king Mesha, especially those over Israel.

Though their language, religion, and culture  were closely related to those of the Israelites, the Moabites were not part  of the Israelite community. David�s great-grandmother Ruth was a  Moabite. The Moabite Stone, a stela discovered in 1868, is the only writ�  ten document of any length that survives from Moab; it tells of King Omri  of Israel�s reconquest of Moabite lands, which the Moabites ascribed to  the anger of their god, Chemosh.

Former name of one of the largest U.S. holding compa�  nies, primarily engaged in petroleum operations but with major interests  in chemical products and retailing. Mobil�s roots are in two 19th-century  oil companies, Vacuum Oil Co. (founded 1866) and Standard Oil Co. of  New York (or Socony, 1882). Their 1931 merger created Socony-Vacuum  Corp., which became Socony Mobil Oil Corp. (1955) and then Mobil Oil  Corp. (1966). In 1974 Mobil Corp., the holding company, was created  when Mobil Oil Corp. bought Marcor Inc. in an effort to diversify. By  1988 Mobil had sold Marcor�s major non-oil-related portions, including  Montgomery Ward, to refocus on petroleum products. Mobil Oil Corp.  developed a full range of petroleum operations from exploration to mar�  keting, with major production in the Gulf of Mexico, California, the Atlan�  tic coast, Alaska, the North Sea, and Saudi Arabia. It merged with Exxon  Corp. to become Exxon Mobil Corp. in 1999.</p><p>Mobile Vmo-.bel, mo-'bel\ City (pop., 2000: 198,915), southwestern  Alabama, U.S. Situated on Mobile Bay at the mouth of the Mobile River,  the site was explored by Spaniards in 1519. French colonists built a fort  near the river�s mouth in 1702. It served as the capital of French Loui�  siana until about 1719. It was ceded to the British in 1763 and captured  by the Spanish during the American Revolution. It was seized by the U.S.  during the War of 1812 and incorporated as a town in 1819. During the  American Civil War it was an important Confederate port, but Federal  forces won the Battle of Mobile Bay and captured the city. The state�s only  seaport, it is a major industrial and manufacturing centre and the site of  several institutions of higher education.</p><p>mobile \'mo-,bel\ Abstract sculpture that has moving parts, driven either  by motors or by the natural force of  air currents.

He began teaching at the Uni�  versity of Leipzig in 1815, and established his reputation with many pub�  lications. His mathematical papers are chiefly concerned with geometry.  He introduced homogeneous coordinates into analytic geometry and dealt  with geometric transformations, in particular projective transformations.  He was a pioneer in topology; in a memoir discovered after his death he  discussed the properties of one-sided surfaces, including the famous  Mobius strip.</p><p>Mobutu Sese Seko Vma-'bii-tu-'sa-sa-'sa-koV orig.

Mobutu served in the Belgian Congolese army and as  a journalist before joining Patrice Lumumba in independence negotiations  in Brussels in 1960. When independence was achieved, the coalition gov�  ernment of Pres. Joseph Kasavubu and Premier Lumumba put Mobutu in  charge of defense. In a rift between Kasavubu and Lumumba, Mobutu  helped Kasavubu seize control. Four years later, in a power struggle  between Pres. Kasavubu and then Premier Moise Tshombe, Mobutu  removed Kasavubu in a coup and assumed the presidency. He established  single-party rule and Africanized all European names, changing his own  to Mobutu Sese Seko (�All-Powerful Warrior�). His repressive regime  failed to spur economic growth; corruption, mismanagement, and neglect  led to decline, while Mobutu himself amassed one of the largest personal  fortunes in the world. He was overthrown by Laurent Kabila in 1997 and  died in exile in Morocco.</p><p>mocambo See quilombo</p><p>moccasin Either of two species of pit viper: the water moccasin or the  Mexican moccasin {Agkistrodon bilineatus).

The most straightforward way of con�  structing a modal logic is to add to some standard nonmodal logical  system a new primitive operator intended to represent one of the modali�  ties, to define other modal operators in terms of it, and to add axioms  and/or transformation rules involving those modal operators. For example,  one may add the symbol L, which means �It is necessary that,� to clas�  sical propositional calculus; thus, Lp is read as �It is necessary that p.� The  possibility operator M (�It is possible that�) may be defined in terms of  L as Mp = �iL�ip (where �i means �not�). In addition to the axioms and  rules of inference of classical propositional logic, such a system might  have two axioms and one rule of inference of its own. Some character�  istic axioms of modal logic are: (Al) Lp z&gt; p and (A2) L(p o q) z&gt; (Lp z&gt;  Lq). The new rule of inference in this system is the Rule of Necessita-  tion: If p is a theorem of the system, then so is Lp. Stronger systems of  modal logic can be obtained by adding additional axioms. Some add the  axiom Lp z&gt; LLp; others add the axiom Mp z&gt; LMp.</p><p>mode In music, any of a variety of concepts used to classify scales and  melodies. In Western music, the term is particularly used for the medieval  church modes. Keys in tonal music are normally said to be in either major or  minor mode, depending particularly on the third degree of the scale. Indian  ragas can be regarded as modes. The concept of mode may involve much  more than simply a classification of scales, extending to embrace an entire  vocabulary of melodic formulas and perhaps other aspects of music that  traditionally occur in tandem with a given set of formulas. The term mode  has also been used for purely rhythmic patterns such as those of the Ars  Antiqua, which were based on ancient Greek poetic metres.</p><p>mode See mean, median, and mode</p><p>Model T Automobile built by the Ford Motor Co. from 1908 until 1927,  the first widely affordable mass-produced car.

Over 15 mil�  lion Model T�s were built. The car was offered in several body styles, all  mounted on a standard chassis. Various colors were initially available, but  after 1913 its sole color was black.

It lies between the Secchia and Panaro  rivers, northwest of Bologna. An ancient Etruscan city, it was made a  Roman colony in 183 bc. It was attacked and pillaged by the Huns under  Attila and later by the Lombards. It passed to the house of Este in 1288.  It was taken by France in 1796 and made part of Napoleon�s kingdom of  Italy in 1805. It reverted to Este rule in 1815 before joining unified Italy  in 1860. The automobile industry is important to its economy; it is also  an agricultural market centre. Sites of interest include the 11th-century  cathedral and the university (founded 1175).</p><p>modern dance Theatrical dance that developed in the U.S. and Europe  in the 20th century as a reaction to traditional ballet. Precursors included  Loie Fuller and Isadora Duncan. Formal teaching of modern dance began</p><p>with the establishment of the Denishawn schools by Ruth St. Denis and Ted  Shawn in 1915. Many of their students, principally Doris Humphrey and  Martha Graham, further contributed to modem dance�s definition as a  technique based on principles of fall and recovery (Humphrey) and of  contraction and release (Graham). Movement often stressed the expres�  sion of emotional intensity and contemporary subjects rather than focus�  ing on the formal, classical, and often narrative aspects of ballet. Later  developments included a revolt in the 1950s against Graham�s expres�  sionism, led by Merce Cunningham, whose choreography included ballet  technique and the element of chance.

It was founded  in 1951 by pianist John Lewis (1920-2001), vibraphonist Milt Jackson  (1923-99), drummer Kenny Clarke (1914-85), and bassist Ray Brown  (1926-2002). They originally worked together as the rhythm section for  Dizzy Gillespie�s big band in 1946. The quartet established a reserved and  subtle approach to the modern jazz innovations of the mid-1940s, incor�  porating elements of classical chamber music with original compositions  and jazz standards. Percy Heath (1923-2005) replaced Brown in 1952,  and Connie Kay (1927-94) replaced Clarke in 1955. The group disbanded  in 1974 but reunited for annual tours beginning in the 1980s. Upon Kay�s  death, Percy�s brother Albert (�Tootie�) Heath (b. 1935) joined the group.</p><p>Modernism In the arts, a radical break with the past and concurrent  search for new forms of expression. Modernism fostered a period of  experimentation in the arts from the late 19th to the mid-20th century,  particularly in the years following World War I. In an era characterized  by industrialization, rapid social change, advances in science and the  social sciences (e.g., Darwinism, Freudian theory), Modernists felt a grow�  ing alienation incompatible with Victorian morality, optimism, and con�  vention. The Modernist impulse is fueled in various literatures by  industrialization and urbanization, by the search for an authentic response  to a much-changed world. Among English-language writers, the best-  known Modernists are T.S. Eliot, James Joyce, Gertrude Stein, and Virginia  Woolf. Composers, including Arnold Schoenberg, Igor Stravinsky, and  Anton Webern, sought new solutions within new forms and used as-yet-  untried approaches to tonality. In dance a rebellion against both balletic  and interpretive traditions had its roots in the work of Emile Jaques-  Delcroze, Rudolf Laban, and Loie Fuller. Each of them examined a specific  aspect of dance�such as the elements of the human form in motion or  the impact of theatrical context�and helped bring about the era of mod�  ern dance. In the visual arts the roots of Modernism are often traced back  to painter Edouard Manet, who beginning in the 1860s broke away from  inherited notions of perspective, modeling, and subject matter. The avant-  garde movements that followed�including Impressionism, Post-  Impressionism, Cubism, Futurism, Expressionism, Constructivism, De Stul, and  Abstract Expressionism �are generally defined as Modernist. Over the span  of these movements, artists increasingly focused on the intrinsic qualities  of their media�e.g., line, form, and colour�and moved away from inher�  ited notions of art. By the beginning of the 20th century, architects also  had increasingly abandoned past styles and conventions in favour of a  form of architecture based on essential functional concerns. In the period  after World War I these tendencies became codified as the International  style, which utilized simple, geometric shapes and unadorned facades and  which abandoned any use of historical reference; the buildings of Lud�  wig Mies van der Rohe and Le Corbusier embodied this style. After World  War II the style manifested itself in clean-lined, unadorned glass sky�  scrapers and mass housing projects.</p><p>Modernismo Spanish-language literary movement of the late 19th�  early 20th century, founded by Ruben Dario. Reacting against the senti�  mental romantic writers then popular in Latin America, modernistas wrote  on exotic themes and often about artificial worlds�the ancient past, the  distant Orient, and the lands of childhood fancy and sheer creation. With  �art for art�s sake� as their creed, they brought about the greatest revital�  ization of language and poetic technique in Spanish since the 17th cen�  tury. Its adherents included Peru�s Jose Santos Chocano (1875-1934) and  Cuba�s Jose Marti. Though the movement was over by 1920, its influence  continued well into the 20th century.</p><p>modernization Transformation of a society from a rural and agrarian  condition to a secular, urban, and industrial one.

After studying art in Italy, he  settled in Paris (1906), where he  exhibited several paintings at the  Salon des Independants in 1908. Fol�  lowing the advice of Constantin  Brancusi, he studied African sculp�  ture and in 1912 exhibited 12 stone  heads whose simplified and elon�  gated forms reflect African influence.  When he returned to painting, his  portraits and nudes�characterized  by asymmetry of composition, elon�  gation of the figure, and a simplifica�  tion of outline�reflected the style of  his sculpture. By almost eliminating  chiaroscuro, he achieved a sculptural  quality by the strength of his contours  and the richness of juxtaposed  colours. In 1917 he began painting a  series of female nudes that, with their  warm, glowing colours and sensu�  ous, rounded forms, are among his  best works. His work reflects his life�  long admiration for Italian Renais�  sance masters, as well as the  influence of Paul Cezanne and Bran�  cusi.

His work on personal savings  prompted him to formulate the life-cycle theory, which asserts that indi�  viduals build up savings during their younger working lives for use dur�  ing their own old age and not as an inheritance for their descendants. In  order to analyze financial markets, he invented a technique for calculat�  ing the value of a company�s expected future earnings that became a basic  tool in corporate decision making and finance.

Their economy was based on hunting and gathering, and they lived  much like their closely related neighbours the Klamath. In 1864 the U.S.  government forced the Modoc to live on Klamath lands, giving rise to the  Modoc War of 1872-73. About 80 families retreated to the California  Lava Beds but eventually surrendered and were removed to Oklahoma.  Survivors were permitted to return to Oregon in 1909. Together with the  Klamath and the Yahooskin band of Snake Indians, they form an entity  known as the Klamath Tribes.

There are various forms of modulation, each designed to alter a  particular characteristic of the carrier wave. The most commonly altered  characteristics include amplitude (see AM), frequency (see FM), phase,  pulse sequence, and pulse duration.</p><p>modulation In music, the transition from one mode or key to another.  There are three principal methods of modulation in classical harmony:  diatonic, in which a pivot chord is common to both keys; chromatic, in  which the notes of the pivot chord are altered by a semitone; and enhar�  monic, in which the notes of the pivot chord, while retaining their origi�  nal tones, simply assume different names. Modulation may be transitory,  as in the course of thematic development, or structural, contributing to  the harmonic definition of the form.</p><p>module \'ma-jiil\ In architecture, a unit adopted to regulate the dimen�  sions, proportions, or construction of the parts of a building. Modules  based on the diameter of a column were used in Classical architecture. In  Japanese architecture, room sizes were determined by combinations of  standard rice mats called tatami. Both Frank Lloyd Wright and Le Corbusier  used modular proportioning systems. Standardized modular design  reduces waste, lowers costs, and offers ease of erection, flexible arrange�  ment, and variety of use; however, most architects and producers of build�  ing materials continue to use modules based on their own special needs  and interests.</p><p>modulus, bulk See bulk modulus</p><p>modus ponens and modus tollens Vm6-d3s-'po-n9nz... , t6-bns\  (Latin: �method of affirming� and �method of denying�) In LOGIC, two  types of inference that can be drawn using a hypothetical proposition�  i.e., from a proposition of the form �If p, then q� (symbolically p z&gt; q).

The first pottery in the Southwest was  made by the Mogollon; its high quality from the beginning suggests that  the craft may have been imported from Mexico. The early economy was  based on gathering wild plant foods and hunting small game. Corn cul�  tivation emerged c. ad 500. At this time houses also became more elabo�  rate, being constructed of stone masonry. In the final, or Mimbres, period  (1050-1200), new patterns of house design (multilevel pueblos centred on  a plaza) and pottery (crisp black-on-white designs of animals or geomet�  ric lines) emerged, suggesting contact with the Anasazi peoples to the  north.

The traditional territory of the people was the  Mojave Desert along the lower Colorado River. This valley was a patch  of green surrounded by barren desert. In addition to farming, the Mojave  fished, hunted, and gathered wild plants. The essential social unit was the  patrilineal family. There were no settled villages; wherever there was  suitable floodland for farming, the Mojave built scattered houses. They  believed in a supreme creator and attached great significance to dreams,  considered the source of all special powers.

The surface of a molding may be plain or modeled with recesses and  reliefs, which either maintain a constant profile along its length or are set  in rhythmically repeated patterns. Types of flat or angular moldings are  the fascia, chamfer (or bevel), and fillet (narrow band). Single curved  moldings include the cavetto (concave, with a quarter-circle profile),  scotia (deep concave), flute (grooved), ovolo (convex, with a quarter-  circle profile), torus (semicircular convex), roll (rounded convex), and  astragal (narrow semicircular convex). Among the most common com�  pound moldings are the projecting, double-curved cyma recta or ogee,  often used as a crown molding, and the cyma reversa, used for crown or  base. The profiles of moldings are traditionally enhanced by flower or leaf  forms, geometric motifs, or spirals.

For any substance, the num�  ber of atoms or molecules in a mole is Avogadro's number (6.02 x 10 23 )  of particles. Defined exactly, it is the amount of pure substance contain�  ing the same number of chemical units that there are in exactly 12 g of  carbon- 12. For each substance, a mole is its atomic weight, molecular  weight, or formula weight in grams. The number of moles of a solute in a  litre of solution is its molarity (M); the number of moles of solute in 1,000  g of solvent is its molality (m). The two measures differ slightly and have  different uses. See also stoichiometry.</p><p>mole Any burrowing, often blind insectivore in the family Talpidae  (including 42 species of true moles) or Chrysochloridae (18 species of  golden moles). Most species have short legs and tail, a pointed head, vel�  vety grayish fur, no external ears, and a strong odour. They range from  3.5 to 8 in. (9 to 20 cm) long. The forelimbs are rotated outward like oars  and have broad or pointed claws on the toes. Moles are active day and  night, digging surface tunnels in search of earthworms, grubs, and other  invertebrates and excavating deep (10 ft [3 m]), vented burrows (mole�  hills) for occupancy. The star-nosed mole (Condylura cristata) of north�  eastern North America has 22 pink, tentacle-like touch organs radiating  from its muzzle.</p><p>mole Pigmented flat or fleshy skin mark, made up mostly of cells that  produce melanin, which gives moles their light to dark brown or black  colour and, in the dermis, a bluish cast. Thicker moles also contain nerve  elements and connective tissue. Moles often begin in childhood, usually  as flat spots between the dermis and epidermis. Those that remain there  are more likely to become malignant. Most move into the dermis and  become slightly raised. In children, moles may undergo changes resem�  bling cancer but are benign. Malignant melanoma can begin in moles but  almost never before puberty. During pregnancy, moles may enlarge and  new ones may appear. Moles sometimes disappear with age. The term  nevus refers to a congenital skin mark, whereas a mole may develop after  birth. Epidermal nevi are usually the same colour as the surrounding skin.</p><p>molecular biology Field of science concerned with the chemical  structures and processes of biological phenomena at the molecular level.  Having developed out of the related fields of biochemistry, genetics, and  biophysics, the discipline is particularly concerned with the study of pro�  teins, nucleic acids, and enzymes. In the early 1950s, growing knowledge of  the structure of proteins enabled the structure of DNA to be described.  The discovery in the 1970s of certain types of enzymes that can cut and  recombine segments of DNA (see recombination) in the chromosomes of  certain bacteria made recombinant-DNA technology possible. Molecular  biologists use that technology to isolate and modify specific genes (see  GENETIC ENGINEERING).</p><p>molecular weight Mass of a molecule of a substance, based on 12  as the atomic weight of carbon- 12. It is calculated in practice by sum�  ming the atomic weights of the atoms making up the substance�s molecu�  lar formula. The molecular weight of a hydrogen molecule (chemical  formula H 2 ) is 2 (after rounding off); for many complex organic molecules  (e.g., proteins, polymers) it may be in the millions.</p><p>molecule Smallest identifiable unit into which a pure substance can be  divided and retain its composition and chemical properties. Division into  still smaller parts, eventually atoms, involves destroying the bonding that  holds the molecule together. For noble gases, the molecule is a single atom;  all other substances have two (diatomic) or more (polyatomic) atoms in  a molecule. The atoms are the same in elements, such as hydrogen (H 2 ),  and different in compounds, such as glucose (C 6 H 12 0 6 ). Atoms always  combine into molecules in fixed proportions. Molecules of different sub�  stances can have the same constituent atoms, either in different propor�  tions, as in carbon monoxide (CO) and carbon dioxide (C0 2 ), or bonded  in different ways (see isomer). The covalent bonds in molecules give them  their shapes and most of their properties. (The concept of molecules has  no significance in solids with ionic bonds.) Analysis with modern tech�  niques and computers can determine and display the size, shape, and con�  figuration of molecules, the positions of their nuclei and electron clouds,  the lengths and angles of their bonds, and other details. Electron micros�  copy can even produce images of individual molecules and atoms. See  also molecular weight.

For aromatic  compounds, the Kekule structure is common, in which each bond is represented by  a dash, carbon atoms are implied where two or more lines meet, and hydrogen  atoms are usually omitted. Bond-line formulas, similar to the Kekule structure, are  often used for complex nonaromatic organic compounds.

Tusk shells, or scapho-  pods, are burrowing mollusks with a shell open at both ends; with the larger end  buried in the sand, they feed on microorganisms captured by the tentacles. The  whelks, like most gastropods (univalves), have a single shell, which is usually coiled;  when threatened, the body can be pulled into the shell, which is closed by a plate  (operculum). Cephalopods have a well-developed head and a foot divided into  numerous tentacles. The two long tentacles of the squid are used to capture prey,  and the short arms transfer food to the mouth.

Area: 0.75 sq mi (1.95 sq km). Population (2005 est.):  32,700. Nearly half of Monaco�s population are French citizens; minori�  ties include Italians and Britons; less than one-fifth of the population are  of Monegasque descent. Language: French (official). Religions: Chris�  tianity (predominantly Roman Catholic [official]); also Judaism. Cur�  rency: euro. Inhabited since prehistoric times, the area was known to the  Phoenicians, Greeks, Carthaginians, and Romans. In 1191 the Genoese  took possession of it. In 1297 the reign of the Grimaldi family began. The  Grimaldis allied themselves with France except for the period from 1524  to 1641, when they were under the protection of Spain. France annexed  Monaco in 1793, and it remained under French control until the fall of  Napoleon, when the Grimaldis returned. In 1815 it was put under the pro�  tection of Sardinia. A treaty in 1861 called for the sale of the towns of  Menton and Roquebrune to France and the establishment of Monaco�s  independence. Monaco, situated along the Cote d'Azur, is one of Europe�s  most luxurious resorts, known for its Monte-Carlo gambling centre, inter�  national sports-car races, and beaches.

The term is now used to refer to countries with  hereditary sovereigns. The monarch was the ideal head of the new nation�  states of the 16th and 17th centuries; his powers were nearly unlimited  (see absolutism), though in Britain Parliament was able to restrict the sov�  ereign�s freedom of action, particularly through the Magna Carta (1215)  and the Bill of Rights (1689). The old idea that the monarch represented  (within the limits of his dominions) the rule of God over all things cul�  minated in the 17th century in the doctrine of the divine right of kings  (see divine kingship), exemplified by Louis XIV. Monarchical absolutism  adapted to the Enlightenment by evolving into �benevolent despotism,� as  typified by the rule of Catherine II of Russia. The French Revolution dealt  absolute monarchy a crushing blow, and World War I effectively destroyed  what remained of it, the rulers of Russia, Germany, and Austria-Hungary  being held responsible for the war and postwar misery. The institution  developed into the constitutional monarchy in western Europe, though  absolute (or near-absolute) monarchies continue to exist in the Middle  East.</p><p>monarchy, constitutional See constitutional monarchy</p><p>monastery Local community or residence of a religious order, particu�  larly an order of monks. Christian monasteries originally developed in  Egypt, where the monks first lived as isolated hermits and then began to  coalesce in communal groups. Monasteries were later found throughout  the Christian world and often included a central space for church, chap�  els, fountain, and dining hall. In the Middle Ages they served as centres  of worship and learning and often played an important role for various  European rulers. The vihara was an early type of Buddhist monastery,  consisting of an open court surrounded by open cells accessible through  an entrance porch. Originally built in India to shelter monks during the  rainy season, viharas took on a sacred character when small stupas and  images of the Buddha were installed in the central court. In western India,  viharas were often excavated into rock cliffs.

The earliest Christian monastic communities were founded in  the deserts of Egypt, most notably by the hermit St. Anthony of Egypt  (251-356). It was given its more familiar cenobitic form by St. Pacho-  mius (c. 290-346). St. Basil the Great composed a very influential rule for  the eastern church, and John Cassian (360-465) helped spread monasti-  cism to western Europe. The Benedictine order, founded by St. Benedict of  Nursia in the 6th century, called for moderation of ascetic practices and  established worship services at regular hours. Throughout the Middle  Ages, monasticism played a vital role not only in spreading Christianity  but also in preserving and adding to literature and learning. It underwent  periodic reforms, notably by the Cluniacs in the 10th century and the Cis�  tercians in the 12th century, and saw the founding of mendicant orders  such as the Dominicans and Franciscans. Monasticism has also been  important in Eastern religions. In early Hindu times (c. 600-200 bc) there  were hermits who lived in groups (ashrams), though they did not lead a  strictly organized communal life. Jainism may be the first religion to have  had an organized monastic life, which was characterized by extreme  asceticism. Buddhist monks observe a moderate rule that avoids extremes  of self-indulgence and self-mortification.</p><p>Monck YmaqkV George, 1st duke of Albermarle (b.

His first paintings were exhibited in 1893;</p><p>his early work reflected the influence of avant-garde trends such as Post-  Impressionism and Cubism. In 1917 Mondrian and three other painters  founded the art periodical and the movement known as De Stijl. The group  advocated a style called �neoplasticism,� which entailed complete rejec�  tion of visually perceived reality as subject matter and the restriction of  a pictorial language to its most basic elements of the straight line, pri�  mary colours, and the neutrals of black, white, and gray. He painted in  this style for the next 20 years, until he fled war-tom Paris for London  and then New York City in 1940. Inspired by the city�s pulsating life and  the new rhythms of musical forms such as jazz, he replaced his austere  patterns with a series of small squares and rectangles that coalesced into  a flow of colourful vertical and horizontal lines. His late masterpieces  (e.g., Broadway Boogie-Woogie , 1942-43) express this new vivacity. The  consistent development of Mondrian�s art toward complete abstraction  was an outstanding feat in the history of modern art, and his work fore�  shadowed the rise of abstract art in the 1940s and �50s.</p><p>moneran See bacteria, prokaryote</p><p>Monet Vmo-'naV Claude (b. Nov. 14, 1840, Paris, France�d. Dec. 5,  1926, Givemy) French landscape painter. Monet spent his early years in  Le Havre, where his first teacher, Eugene Boudin, taught him to paint in  the open air. Moving to Paris, he formed lifelong friendships with other  young painters, including Pierre-Auguste Renoir, Alfred Sisley, and Paul  Cezanne. Beginning in the mid 1860s, Monet pursued a new style; rather  than trying to reproduce faithfully the scene before him in detail, he  recorded on the spot the impression that relaxed, momentary vision might  receive. In 1874 he helped organize an independent exhibition, apart from  the official Salon, of work he and his friends produced in this style. One  of Monet�s works at the exhibition, Impression: Sunrise (1872), inspired  the journalist Louis Leroy to give the group its name. Throughout the  1870s, Monet and the other Impressionists explored this style and exhib�  ited together. By 1881 the original group had begun to disintegrate; only  Monet continued with the same fervour to carry on the scrutiny of nature.  In his mature works Monet developed his method of producing a series  of several studies of the same motif (e.g., haystacks, 1891, and Rouen  Cathedral, 1894), changing canvases as the light or his interest shifted. In  1893, in the garden at his home in Giverny, Monet created the water-lily  pond that inspired his most famous works, the lyrical Nympheas (water-  lilies) paintings. Wildly popular retrospective exhibitions of his work  toured the world during the last decades of the 20th century and estab�  lished his unparalleled public appeal, sustaining his reputation as one of  the most significant and popular figures in the modern Western painting  tradition.</p><p>monetarism School of economic thought that maintains that the money  supply is the chief determinant of economic activity. Milton Friedman and  his followers promoted monetarism as an alternative to Keynesian eco�  nomics (see John Maynard Keynes); their economic theories became influ�  ential in the 1970s and early 1980s. Monetarism holds that a change in  the money supply directly affects and determines production, employ�  ment, and price levels, though its influence is evident only over a long  and often variable period of time. Fundamental to the monetarist approach  is the rejection of fiscal policy in favour of �monetary rule.� Friedman and  others asserted that fiscal measures such as tax-policy changes or  increased government spending have little significant effect on the fluc�  tuations of the business cycle. They argued that government intervention in  the economy should be kept to a minimum and asserted that economic  conditions would change before specific policy measures designed to  address them could take effect. Steady, moderate growth of the money  supply, in their view, offered the best hope of assuring a constant rate of  economic growth with low inflation. U.S. economic performance in the  1980s cast doubts on monetarism, and the proliferation of new types of  bank deposits made it difficult to calculate the money supply.</p><p>monetary policy Measures employed by governments to influence  economic activity, specifically by manipulating the money supply and inter�  est rates. Monetary and fiscal policy are two ways in which governments  attempt to achieve or maintain high levels of employment, price stabil�  ity, and economic growth. Monetary policy is directed by a nation�s cen�  tral bank. In the U.S., monetary policy is the responsibility of the Federal  Reserve System, which uses three main instruments: open-market operations,  the discount rate, and reserve requirements. In the post-World War II era,  economists reached a consensus that, in the long run, inflation results  when the money supply grows at too rapid a rate.

It is the medium in which prices and values are expressed;  it circulates from person to person and country to country, thus facilitat�  ing trade. Throughout history various commodities have been used as  money, including seashells, beads, and cattle, but since the 17th century  the most common forms have been metal coins, paper notes, and book�  keeping entries. In standard economic theory, money is held to have four  functions: to serve as a medium of exchange universally accepted in return  for goods and services; to act as a measure of value, making possible the  operation of the price system and the calculation of cost, profit, and loss;  to serve as a standard of deferred payments, the unit in which loans are  made and future transactions are fixed; and to provide a means of storing  wealth not immediately required for use. Metals, especially gold and sil�  ver, have been used for money for at least 4,000 years; standardized coins  have been minted for perhaps 2,600 years. In the late 18th and early 19th  century, banks began to issue notes redeemable in gold or silver, which  became the principal money of industrial economies. Temporarily during  World War I and permanently from the 1930s, most nations abandoned  the gold standard. To most individuals today, money consists of coins,  notes, and bank deposits. In terms of the economy, however, the total  money supply is several times as large as the sum total of individual money  holdings so defined, since most of the deposits placed in banks are loaned  out, thus multiplying the money supply several times over. See also soft  MONEY.</p><p>money, quantity theory of Economic theory relating changes in  the price level to changes in the quantity of money. It has often been used  to analyze the factors underlying inflation and deflation. The quantity  theory was developed in the 17th and 18th centuries by philosophers such  as John Locke and David Hume and was intended as a weapon against mer�  cantilism. Drawing a distinction between money and wealth, advocates of  the quantity theory argued that if the accumulation of money by a nation  merely raised prices, the mercantilist emphasis on a favourable balance of  trade would only increase the supply of money without increasing wealth.  The theory contributed to the ascendancy of free trade over protectionism.  In the 19th-20th centuries it played a part in the analysis of business cycles  and in the theory of rates of foreign exchange.</p><p>money market Set of institutions, conventions, and practices whose  aim is to facilitate the lending and borrowing of money on a short-term  basis. The money market is, therefore, different from the capital market,  which is concerned with medium- and long-term credit. The transactions  that occur on the money market involve not only banknotes but assets  that can be turned into cash at short notice, such as short-term govern�  ment securities and bills of exchange. Though the details and mechanism of  the money market vary greatly from country to country, in all cases its  basic function is to enable those with surplus short-term funds to lend and  those with the need for short-term credit to borrow. This function is  accomplished through middlemen who provide their services for a profit.  In most countries the government plays a major role in the money mar�  ket, acting both as a lender and borrower and often using its position to  influence the money supply and interest rates according to its monetary policy.  The U.S. money market covers financial instruments ranging from bills  of exchange and government securities to funds from clearinghouses and  certificates of deposit. In addition, the Federal Reserve System provides con�  siderable short-term credit directly to the banking system. The interna�  tional money market facilitates the borrowing, lending, and exchange of  currencies between countries.</p><p>money order Certificate requiring the issuer to pay a certain sum of  money on demand to a specific person or organization. Money orders pro�  vide a fast, safe, and convenient means of transferring small sums of  money. They are issued by governments (usually through postal authori�  ties), banks, and other qualified institutions to buyers who pay the issuer  the face amount of the money order plus a service charge. Because they  are exchangeable for cash on demand, they are a generally accepted means  of payment. The American Express Co. began issuing money orders in  1882; the company also created the first traveler�s checks nine years later.  See also currency.</p><p>money supply Liquid assets held by individuals and banks. The  money supply includes coins, currency, and demand deposits (checking  accounts). Some economists consider time and savings deposits to be part  of the money supply because such deposits can be managed by govern�  mental action and are nearly as liquid as currency and demand deposits.  Other economists believe that deposits in mutual savings banks, savings</p><p>and loan associations, and credit unions should be counted as part of the  money supply. Central banks regulate the money supply to stabilize their  national economies. See also monetary policy.</p><p>Mongke \'moq-ka\ (b. 1208, Mongolia�d. 1259, Sichuan province,  China) Mongol leader. Grandson of Genghis Khan and brother of Kublai  Khan, he was elected great khan in 1251. Under Mongke, the Mongols  conquered Iran, Iraq, and Syria as well as the Thai kingdom of Nan-chao  and the area of present-day Vietnam. He died before the Mongols could  complete the conquest of China, which happened under the reign of  Kublai.</p><p>Mongkut X.moq-'kiitV or Phrachomklao N.pra-.kom-'klauV or  Rama IV (b. Oct. 18, 1804, Bangkok, Siam�d. Oct. 15, 1868, Bangkok)  King of Siam (Thailand; r. 1851-68). The 43rd child of King Rama II,  he was a Buddhist monk and scholar before he ascended the throne. His  reformed Buddhism grew into the Thammayut order, which today occu�  pies the intellectual centre of Thai Buddhism. Mongkut�s intellectual pur�  suits also brought him into contact with Western thought. As king, he fully  opened Siam to Western commerce and combined tolerance and shrewd�  ness to help ensure its survival as an independent nation. The reminis�  cences of an English governess employed in his household became the  basis for the musical comedy The King and I.</p><p>Mongo Any of several peoples living in the African equatorial forest.  They speak a dialect of a common language, Mongo or Nkundo, which  belongs to the Niger-Congo language family. The Mongo traditionally  cultivated cassava and bananas in addition to hunting, fishing, and gath�  ering. Mongo religion emphasizes ancestor worship and nature spirits; it  also features magic and witchcraft. Their art has been mainly oral, and  they have a rich talking-drum and song literature. They number some five  million.</p><p>Mongol Member of an Asian people originally from the Mongolian pla�  teau who share a common language and a nomadic tradition of herding  sheep, cattle, goats, and horses. In the 10th�12th centuries the Khitans  (see Liao dynasty), Juchen (Chin dynasty), and Tatars, all Mongol peoples,  ruled in Mongolia, but Mongol power was greatest in the 13th century,  when Genghis Khan, his sons (including Ogodei), and his grandsons Batu  and Kublai Khan, created one of the world�s largest empires. It declined  greatly in the 14th century, when China was lost to the Ming dynasty, and  the Golden Horde was defeated by Muscovy. Ming incursions effectively  ended Mongol unity, and by the 15th-16th centuries only a loose federa�  tion existed. Today the plateau is divided between independent Mongolia  and Chinese-controlled Inner Mongolia. Other Mongols live in Siberia.  Tibetan Buddhism is the principal Mongol religion.</p><p>Mongol dynasty See Yuan dynasty</p><p>Mongolia or Outer Mongolia Country, north-central Asia, between  Russia and China. Area: 603,909 sq mi (1,564,116 sq km). Population  (2005 est.): 2,550,000. Capital: Ulaanbaatar. Some four-fifths of the popu�  lation are Mongols; minorities consist of Kazakhs, Russians, and Chinese.  Languages: Khalkha Mongolian, Turkic languages, Russian, Chinese.  Religions: traditional beliefs. Buddhism, Islam. Currency: tugrik. Mon�  golia has an average elevation of about 5,200 ft (1,580 m) above sea level.  Three mountain ranges stretch across the north and west: the Altai, the  Hangayn (Khangai), and the Hentiyn (Khentei). The south and east are  occupied by the Gobi Desert. Livestock raising, especially sheepherding,  accounts for nearly three-fourths of the total value of agricultural pro�  duction; wheat is the major crop. Mongolia�s rich mineral resources  include coal, iron ore, and copper. Mongolia is a republic with one leg�  islative house; its chief of state is the president, and the head of govern�  ment is the prime minister. In Neolithic times it was inhabited by small  groups of hunters and nomads. During the 3rd century bc it became the  centre of the Xiongnu tribal league. Turkic-speaking peoples held sway  in the 4th-10th centuries ad. In the early 13th century Genghis Khan united  the Mongol tribes and conquered Central Asia. His successor, Ogodei,  conquered the Jin dynasty of China in 1234. Kublai Khan established the  Yuan (Mongol) dynasty in China in 1279. The Mongols were confined to  their original homeland in the steppes after the 14th century. Ligdan Khan  (ruled 1604-34) attempted to unite Mongol tribes against the Manchu,  but after his death the Mongols became part of the Chinese Qing dynasty.  After the fall of the Qing in 1912, Mongol princes, supported by Russia,  declared Mongolia�s independence from China, and in 1921 the Soviet  Red Army helped drive off Chinese and Russian forces.

The country adopted a new constitution in  1992 and shortened its name to Mongolia.</p><p>Mongolian languages Family of</p><p>about eight Altaic languages spoken by five to seven million people in  central Eurasia. All Mongolian languages are relatively closely related;  those languages whose speakers left the core area in Mongolia the ear�  liest tend to be the most divergent. The most remote language is Mo-  gholi (Moghul, Mongol), now spoken by fewer than 200 people in western  Afghanistan. Less divergent are the languages of several ethnic groups in  northwestern China, eastern Qinghai, and adjacent parts of Gansu and  Inner Mongolia, altogether spoken by fewer than 500,000 people. The  core languages are Mongolian proper, the dominant dialect in the Repub�  lic of Mongolia and the basis of Modern Standard Mongolian, and a group  of peripheral dialects. The core group of Mongolian speakers tradition�  ally have used Classical Mongolian as their literary language; it is writ�  ten in a vertical alphabetic script borrowed from the Uighurs (see Turkic  languages). Modern Mongolian was written in this script until 1946, when  the People�s Republic of Mongolia introduced a script using a modified  Cyrillic alphabet. With political democratization in the 1990s, the old script  has been revived. In Inner Mongolia it has been in continuous use.</p><p>Mongoloid See race</p><p>mongoose Any of the 37 species of carnivores constituting the family  Herpestidae, found in Africa, Asia, and southern Europe. Rudyard Kipling�s  famous �Rikki-tikki-tavi� was an Indian, or gray, mongoose ( Herpestes  edwardsiiy, the meerkat is also a member of the mongoose family. Species  range from 7 to 35 in. (17 to 90 cm) long, excluding the furry 6-12-in.  (15-30-cm) tail. Mongooses have short legs, a pointed nose, and small  ears. Most species are active during the day. The gray to brown fur may  have light flecks or dark markings. Mongooses live in burrows, alone, in  pairs, or in large groups, and they eat small mammals, birds, reptiles, eggs,  and fruit. A few species are semiaquatic. Though not immune to venom,  some species attack and kill poisonous snakes by cracking the skull with  a powerful bite.</p><p>monism Vmo-.ni-zomV In metaphysics, the doctrine that the world is  essentially one substance or contains only one kind of substance. Monism  is opposed both to dualism and to pluralism. Examples of monism include  materialism, pantheism, and metaphysical idealism. See also Benedict de  Spinoza.</p><p>monitor Ironclad warship originally designed for use in shallow har�  bours and rivers to blockade the Confederate states in the American Civil  War. The original ironclad, built by John Ericsson, was named Monitor  Its innovative design included minimal exposure above the waterline, a</p><p>heavily armoured deck and hull, and a revolving gun turret. The incon�  clusive Battle of the Monitor and Merrimack (1862) was the first between  ironclad warships. Never seaworthy, the Monitor sank during a gale off  Cape Hatteras that same year, but the U.S. Navy built many improved  monitors during the war. The British navy kept its monitors in service as  late as World War II.</p><p>Monitor and Merrimack, Battle of the (March 9, 1862) Naval  engagement in the American Civil War at Hampton Roads, Va. The Merri�  mack, originally a federal frigate, had been salvaged by the Confederates,  fitted with iron armor, and renamed the Virginia. It sank several wooden  Union warships before meeting the Union�s Monitor. After a four-hour  battle, both ships were damaged, but each side claimed victory. Both ships  were destroyed later in 1862, the Virginia by its crew to avoid capture and  the Monitor in a storm. The battle is notable as history�s first duel between  ironclad warships and as the beginning of a new era in naval warfare.</p><p>monitor lizard Any of about 30 species of lizards (genus Varanus,  family Varanidae), found in the Old World tropics and subtropics. Most  have an elongated head and neck, a heavy body, a long tail, and well-  developed legs. The smallest monitor grows to 8 in. (20 cm), but several  species (e.g., the Komodo dragon) are very large. The two-banded, or  water, monitor (V salvator), of South Asia, grows to 9 ft (2.7 m). The  perenty ( V. giganteus ), of Australia, grows to 8 ft (2.4 m). The so-called  earless monitor ( Lanthanotus borneensis), a rare lizard of Borneo and the  only species of the family Lanthanotidae, grows to 16 in. (40 cm) long.</p><p>monk See monasticism</p><p>Monk, Meredith (Jane) (b. Nov. 20, 1942, Lima, Peru) Peruvian-  born U.S. composer and performance artist. She was raised in Connecti�  cut and New York and attended Sarah Lawrence College. She soon formed  her first group, The House (1968), to explore extended vocal techniques  (many learned from study of other cultures) in combination with dance,  film, theatre, and other elements, in genre-defying works such as Juice  (1969). One of the original creators of performance art, she has remained  unique and unclassifiable.</p><p>Monk, Thelonious (Sphere) (b. Oct. 10, 1917, Rocky Mount, N.C.,  U.S.�d. Feb. 17, 1982, Englewood, N.J.) U.S. jazz pianist and composer.  Monk grew up in New York City. He worked as the house pianist at Mint�  on�s Playhouse in New York (1940^-3), where the expanding harmonic  vocabulary of bebop was developed. He performed with Coleman Hawk�  ins, Cootie Williams (19087-85), and Dizzy Gillespie before making record�  ings under his own name beginning in 1947. His highly idiosyncratic,  percussive playing made frequent use of sharp dissonances and insistent  rhythms unusual in jazz. His best-known composition, ��Round Mid�  night,� has become a jazz standard.</p><p>monkey Any member of two tropical anthropoid primate groups: Old  World monkeys and New World monkeys. Almost all species are tropi�  cal or subtropical, and almost all are diurnal. Most species are arboreal,  using all four limbs to leap from tree to tree. They can sit upright and  stand erect. Most species run along branches rather than swinging arm  over arm like the apes. Monkeys are highly social omnivores, organized  in clans as large as several hundred individuals headed by an old male.  Sexually mature males of all species are always potent, and all nonpreg�  nant females have a monthly menstrual cycle. Most species bear a single  young, which is reared by the mother for years.</p><p>monkey puzzle tree Evergreen  ornamental and timber conifer  (Araucaria araucana ) of the family  Araucariaceae, native to the Andes  Mountains of South America.

The monkeypox virus is usually found in primates  and rodents in Central and West Africa but has spread to other parts of  the world through the export of infected small mammals. It can be trans�  mitted to humans through an animal bite and from person to person  through prolonged close contact. Symptoms of the disease include fever,  headache, general malaise and fatigue, and swollen lymph nodes. A rash  of raised bumps appears on the infected person�s face and body. Treat�  ment is limited to alleviating symptoms. Outbreaks are contained by iso�  lating patients and controlling the trade of animals.</p><p>monkfish Any of 10-12 species (genus Squatinci, family Squatinidae)  of sharks having a flattened head and body, with winglike pectoral and  pelvic fins that make them resemble rays. The tail bears two dorsal fins,  and behind each eye is a prominent spiracle. Monkfish grow up to 6.25  ft (2.5 m) long. They inhabit tropical and warm temperate waters of con�  tinental shelves worldwide. The angelfish, or angel shark ( S. squatina ),  is often caught for food in European waters. The term monkfish is also  used for the unrelated food species of the genus Lophius, bottom-dwelling  goosefish with enormous mouths and �fishing rod� lures extending from  their heads.</p><p>Monmouth Vman-mothX, James Scott, duke of orig. James  Fitzroy or James Crofts (b.</p><p>April 9, 1649, Rotterdam, Neth.�d.  July 15, 1685, London, Eng.) British  military leader. The illegitimate son  of Charles II of England, he lived in  Paris with his mother. In 1662 he was  brought to England as a favourite of  the king, who created him duke of  Monmouth. He married the Scottish  heiress Anne Scott, duchess of Buc-  cleuch, and took her surname. A  member of the king�s guard from  1668, he commanded troops in the  Anglo-Dutch War and against Scot�  tish rebels in 1679. He was champi�  oned for the royal succession by the  anti-Catholic Whigs, but after the  unsuccessful Rye House Plot he took</p><p>refuge in the Netherlands (1684).  Returning after Charles�s death to  challenge James II, he and his army of  peasants were defeated, and he was  captured and beheaded.</p><p>Duke of Monmouth, oil painting after  W.

In World War II he chaired a Franco-British economic commit�  tee and proposed a Franco-British union. In 1947 he created and directed  the successful Monnet Plan to rebuild and modernize France�s economy.  In 1950, with Robert Schuman, he proposed the plan for the European Coal  and Steel Community, predecessor of the European Economic Community and  the European Union, and served as its first president (1952-55).

Feb. 9, 1910, Paris,  France�d. May 31, 1976, Cannes) French biochemist. In 1961 he and  Francois Jacob proposed the existence of messenger RNA (mRNA), theo�  rizing that the messenger carries the information encoded in the base  sequence to the ribosomes, where the sequence of bases of the messenger  RNA is translated into the sequence of amino acids of a protein. In advanc�  ing the concept of gene complexes that they called operons, they suggested  the existence of a class of genes that regulate the function of other genes  by regulating the synthesis of mRNA. The two shared a 1965 Nobel Prize  with Andre Lwoff (1902-94).</p><p>monody \'ma-no-de\ Accompanied solo song style of the early 17th  century. It represented a reaction against the contrapuntal style (based on  the combination of simultaneous melodic lines) of the 16th-century mad�  rigal and motet. Ostensibly in an attempt to emulate ancient Greek music,  composers placed renewed emphasis on proper articulation as well as  expressive interpretation of texts, and they thus replaced counterpoint with</p><p>simply accompanied recitative. This resulted in a decisive distinction  between melody and accompaniment, which coincides with the early  appearance of basso continuo. A collection of songs published by Giuuo  Caccini in 1602 exemplifies early monody. See also opera; recitative.</p><p>monogram Originally a cipher consisting of a single letter, later a  design or mark consisting of two or more letters intertwined. The letters  thus interlaced may be either all the letters of a name or the initial letters  of the given names and surname of a person for use on notepaper, seals,  or elsewhere. Many early Greek and Roman coins bear the monograms  of rulers or towns. Most famous is the sacred monogram, which is formed  by the conjunction of the first two Greek letters of XPIETOE (Christ),  usually with the a (alpha) and co (omega) of the Apocalypse on each side  of it. The Middle Ages were extremely prolific in inventing ciphers for  ecclesiastical, artistic, and commercial use. Related devices are the colo�  phons used for identification by publishers and printers, the hallmarks of  goldsmiths and silversmiths, and the logos adopted by corporations.</p><p>monomer Vma-no-marX Molecule of any of a class of mostly organic  compounds that can react with other molecules of the same or other com�  pounds to form very large molecules (polymers). The essential feature of  monomer molecules is the ability to form chemical bonds (see bonding)  with at least two other monomer molecules (polyfunctionality). Those  able to react with two others can form only chainlike polymers; those able  to react with three or more can form cross-linked, network polymers.  Examples of monomers (and their polymers) are styrene (polystyrene),  ETHYLENE (POLYETHYLENE), and AMINO ACIDS (PROTEINS).</p><p>Monongahela \m9-,nan-g9- , he-b\ River River, northern West Vir�  ginia, U.S. It flows north past Morgantown into Pennsylvania and joins  the Allegheny River at Pittsburgh to form the Ohio River, after a total course  of 128 mi (206 km). In its upper reaches it is used for hydroelectric power.  Made navigable by means of locks for 106 mi (170 km), it serves as a  major barge route.</p><p>mononucleosis X.ma-no-.nii-kle-'o-sosV infectious or glandular  fever Common infection, caused by Epstein-Barr virus. It occurs most  often at ages 10-35. Infected young children usually have little or no ill�  ness but become immune. Popularly called �the kissing disease,� it is  spread mostly by oral contact with exchange of saliva. It usually lasts 7-14  days. The most common symptoms are malaise, sore throat, fever, and  lymph-node enlargement. Liver involvement is usual but rarely severe.  The spleen often enlarges and in rare cases ruptures fatally. Less frequent  features include rash, pneumonia, encephalitis (sometimes fatal), meningitis,  and peripheral neuritis. Relapse and second attacks are rare. Diagnosis may  require blood analysis. There is no specific therapy.</p><p>monophony Xmo-'na-fo-neV Music consisting of a single unaccompa�  nied melodic line. The concept often also includes melody that is accom�  panied by a drone or by drumming. Gregorian chant and Byzantine chant  constitute the oldest written examples of monophonic repertory.</p><p>Monophysite heresy \m3-'na-f9- l sit\ (5th-6th century ad) Doctrine  that emphasized the single nature (the term means literally �of one nature�)  of Christ, as a wholly divine being rather than part-divine and part-human.  Monophysitism began to appear in the 5th century; though condemned as  a heresy at the Council of Chalcedon (451), it was tolerated by such Byz�  antine leaders as Justin II, Theodora, and Zeno, resulting in a full-fledged  schism between East and West. Several Monophysite churches, including  the Coptic Orthodox Church, were founded in the 6th century.</p><p>monopolistic competition Market situation in which many inde�  pendent buyers and sellers may exist but competition is limited by spe�  cific market conditions. The theory was developed almost simultaneously  by Edward Hastings Chamberlin in his Theory of Monopolistic Compe�  tition (1933) and Joan V. Robinson in her Economics of Imperfect Com�  petition (1933). It assumes product differentiation, a situation in which  each seller�s goods have some unique properties, thereby giving the seller  some monopoly power. See also monopoly; oligopoly.</p><p>monopoly Exclusive possession of a market by a supplier of a prod�  uct or service for which there is no substitute. In the absence of compe�  tition, the supplier usually restricts output and increases price in order to  maximize profits. The concept of pure monopoly is useful for theoretical  discussion but is rarely encountered in actuality. In situations where hav�  ing more than one supplier is inefficient (e.g., for electricity, gas, or water),  economists refer to �natural monopoly� (see public utility). For monopoly  to exist there must be a barrier to the entry of competing firms. In the case</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>monoprint &#x25BA; Monroe I 1285</p><p>of natural monopolies, the government creates that barrier. Either local  government provides the service itself, or it awards a franchise to a pri�  vate company and regulates it. In some cases the barrier is attributable to  an effective patent. In other cases the barrier that eliminates competing  firms is technological. Large-scale, integrated operations that increase  efficiency and reduce production costs confer a benefit on firms that adopt  them and may confer a benefit on consumers if the lower costs lead to  lower product prices. In many cases the barrier is a result of anticompet�  itive behaviour on the part of the firm. Most free-enterprise economies  have adopted laws to protect consumers from the abuse of monopoly  power. The U.S. antitrust laws are the oldest examples of this type of  monopoly-control legislation; public-utility law is an outgrowth of the  English common law as it pertains to natural monopolies. Antitrust law  prohibits mergers and acquisitions that lessen competition. The question  asked is whether consumers will benefit from increased efficiency or be  penalized with a lower output and a higher price. See also oligopoly.</p><p>monoprint See monotype</p><p>monopsony \m3-'nap-s9-ne\ In economic theory, market situation in  which there is only one buyer. An example of pure monopsony is a firm  that is the only buyer of labour in an isolated town; such a firm would be  able to pay lower wages to its employees than it would if other firms were  present. Though cases of pure monopsony are rare, monopsonistic ele�  ments are found wherever there are many sellers and few purchasers.</p><p>monorail Electric railway that runs on a single rail either above or under  the railway cars. The first systems were introduced in the early 20th cen�  tury; the earliest probably opened in 1901 in Wuppertal, Germany. Short-  run monorails have since been built in such cities as Tokyo and Seattle.  Because of higher costs and slower speeds than conventional rail systems,  the monorail has not gained wide support. High-speed monorail vehicles  that use magnetic levitation have been undergoing research for many  years.</p><p>monosaccharide \ l ma-n3- , sa-k3- l nd\ Any of the simple sugars that  serve as building blocks for carbohydrates. They are classified based on  their backbone of carbon (C) atoms: Trioses have three carbon atoms,  tetroses four, pentoses five, hexoses six, and heptoses seven. The carbon  atoms are bonded to hydrogen atoms (�H), hydroxyl groups (�OH; see  functional group), and carbonyl groups (�C=0), whose combinations,  order, and configurations allow a large number of stereoisomers (see iso�  mer) to exist. Pentoses include xylose, found in woody materials; arabi-  nose, found in gums from conifers; ribose, a component of RNA and  several vitamins; and deoxyribose, a component of DNA. Important hex�  oses include glucose, galactose, and fructose. Monosaccharides combine  with each other and other groups to form a variety of disaccharides,  polysaccharides, and other carbohydrates.</p><p>monosodium glutamate (MSG) White crystalline substance, a  sodium salt of the amino acid glutamic acid. MSG is used to intensify the  natural flavour of meats and vegetables. It elicits a unique taste, called in  Japan umami, different from the four basic tastes. Originally derived from  seaweed and first used in Japan in 1908, it has become a common ingre�  dient in Chinese and Japanese cooking. MSG in large amounts may have  physical effects, including an allergic reaction commonly called �Chinese  restaurant syndrome.�</p><p>monotheism Vma-no-.the-.i-zonA Belief in the existence of one god.  It is distinguished from polytheism. The earliest known instance of mono�  theism dates to the reign of Akhenaton of Egypt in the 14th century bc.  Monotheism is characteristic of Judaism, Christianity, and Islam, all of  which view God as the creator of the world, who oversees and intervenes  in human events, and as a beneficent and holy being, the source of the  highest good. The monotheism that characterizes Judaism began in  ancient Israel with the adoption of Yahweh as the single object of wor�  ship and the rejection of the gods of other tribes and nations without, ini�  tially, denying their existence. Islam is clear in confessing one, eternal,  unbegotten, unequaled God, while Christianity holds that a single God is  reflected in the three persons of the Holy Trinity.</p></section><section><p>monotreme Vma-no-.tremX Any of three living species of egg-laying  maaamals (order Monotremata): the platypus and two species of echidna.  Monotremes are found only in Australia, Tasmania, and New Guinea.  Except for their egg laying, they have mammalian characteristics, such as  mammary glands, hair, and a complete diaphragm. They lack teats; the  young suck milk through pores on the mother�s skin. The earliest fossil</p><p>monotremes, found in Australia, are only about 2 million years old and  differ little from present species. Monotremes probably originated from a  line of mammal-like reptiles different from the line that gave rise to pla�  cental mammals and marsupials.</p><p>monotype or monoprint In art printmaking, a technique prized  because of its unique textural qualities. Monotypes are made by drawing  with printer�s ink or oil paint onto glass or a plate of metal or stone. The  drawing is then pressed by hand onto a sheet of absorbent paper or printed  on an etching press. The pigment remaining on the plate is usually insuf�  ficient to make another print unless the original design is reinforced. Sub�  sequent prints invariably differ from the first, because variations in  repainting and printing are inevitable. In the 19th century, William Blake  and Edgar Degas experimented with the technique.</p><p>Monro family Family of Scottish physicians. Three generations of the  family made the University of Edinburgh an international centre of medi�  cal teaching, holding the chair of anatomy for 126 years (1720-1846)  without interruption. Alexander primus (b. Sept. 8, 1697, London,  Eng.�d. July 10, 1767, Edinburgh, Scot.) lectured in anatomy and sur�  gery; his anatomical preparations were outstanding, and, though not a  surgeon, he advanced many new ideas for instruments and dressings. His  son Alexander secundus (b. May 22, 1733, Edinburgh�d. Oct. 2, 1817,  Edinburgh) began lecturing in his second year of medical study; of the  three, he is judged the greatest teacher and anatomist, and his research  also covered pathology and physiology. Alexander tertius (b. Nov. 5,  1773, Edinburgh�d. March 10, 1859, Craiglockheart, near Edinburgh)  relied largely on the notes handed down to him.</p><p>Monroe, Bill orig. William Smith Monroe (b.

Monroe began to play professionally in 1927 and later toured with  his brother Charlie. They made their first recordings in 1936 and recorded  60 songs over the next two years. He formed the Blue Grass Boys in 1939.  His bluegrass sound emerged fully in 1945, when banjoist Earl Scruggs  (b. 1924) and guitarist Lester Flatt joined his band. The Blue Grass Boys  established the classic makeup of a bluegrass group�mandolin, fiddle,  guitar, banjo, and upright bass�and bequeathed its name to the genre  itself. Monroe continued to perform until shortly before his death.</p><p>Monroe, Harriet (b. Dec. 23, 1860, Chicago, Ill., U.S.�d. Sept. 26,  1936, Arequipa, Peru) U.S. editor. She worked on various newspapers in  the city as an art and drama critic while privately writing verse and verse  plays. In 1912 she founded Poetry magazine, securing the backing of  wealthy patrons and inviting contributions from a wide range of poets.  Monroe�s open-minded editorial policy and awareness of the importance  of the Modernist revolution in contemporary poetry made her a major  influence in its development.</p><p>Monroe, James (b.

After serving in the American  Revolution, he studied law under  Thomas Jefferson, then governor of  Virginia. From 1783 to 1786 he  served in the Congress under the  Articles of Confederation. In 1790 he  was elected to the U.S. Senate,  where he opposed the adminstration  of George Washington.

Her vulnerability and sen�  suousness combined with her death raised her to the status of an Ameri�  can cultural icon.</p><p>Monroe Doctrine U.S. foreign-policy statement first enunciated by  Pres. James Monroe on Dec. 2, 1823, declaring the Western Hemisphere  off-limits to European colonization. Concerned that the European powers  would attempt to restore Spain�s former colonies, he declared, inter alia,  that any attempt by a European power to control any nation in the West�  ern Hemisphere would be viewed as a hostile act against the U.S. It was  reiterated in 1845 and 1848 by Pres. James K. Polk to discourage Spain  and Britain from establishing footholds in Oregon, California, or on Mexi�  co�s Yucatan Peninsula. In 1865 the U.S. massed troops on the Rio Grande  to back up demands that France withdraw from Mexico. In 1904 Pres.  Theodore Roosevelt added the Roosevelt Corollary, stating that in the event  of flagrant wrongdoing by a Latin AMERiCAn state, the U.S. had the right  to intervene in its internal affairs. As the U.S. became a world power, the  Monroe Doctrine came to define the Western Hemisphere as a U.S. sphere  of influence.

The most prominent examples occur in Africa and southern  Asia. The primary cause of monsoons is the difference between annual  temperature trends over land and sea. Seasonal changes in temperature  are large over land but small over oceans. A monsoon blows from cold  toward warm regions: from sea toward land in summer and from land</p><p>toward sea in winter.

Over the cen�  turies it has been a pilgrimage center, fortress, and prison. The fine abbey  church has an imposing 11th-century Romanesque nave and an elegant  Flamboyant-style Gothic choir. The exterior walls of the Gothic monastery  building combine the power of a military fortress and the simplicity of a  religious building. Some of the houses bordering the island�s narrow,  winding streets date back to the 15 th century.</p><p>montage \man-'tazh\ French "mounting" Pictorial technique in  which cut-out illustrations, or fragments of them, are arranged together  and mounted on a support, producing a composite picture made from sev�  eral different pictures. It differs from collage in using only ready-made  images chosen for their subject or message. The technique is widely used  in advertising. Photomontage uses photographs only. In motion pictures,  montage is the sequential assembling of separate pieces of thematically  related film by the director, film editor, and visual and sound technicians,  who cut and fit each part with the others to produce visual juxtapositions  and complex audio patterns.</p><p>Montagnais and Naskapi \ l man-t3n-'ya... , nas-k3-pe\ Two related  North American Indian peoples living in Quebec and Labrador, Can. They  speak almost identical Algonquian dialects. The Montagnais, whose name  is French, meaning �Mountaineers,� traditionally occupied a large for�  ested area above the northern shores of the Gulf of St. Lawrence. They  lived in birch-bark wigwams and subsisted on moose, salmon, eel, and  seal. The Naskapi, whose name is derived from a Montagnais word mean�  ing �savage,� lived farther north on the Labrador plateau, where they  hunted caribou and fished. Both groups used canoes in summer and sleds  and snowshoes in winter. Religious belief centred on manitou, or super�  natural power; much importance was attached to nature and animal spir�  its. The basic social unit was the nomadic band. Both groups now call  themselves Innu�not to be confused with Inuit (see Eskimo) �meaning  �People.� Together the Montagnais and Naskapi total some 20,000, the  vast majority of whom are Montagnais.</p><p>Montagnard \ 1 mo n -,tan- , yar\ French "Mountain Man" Radical  deputy in the National Convention during the French Revolution.

On their return, they introduced the Middle East�  ern practice of smallpox vaccination into England. Also a poet, essayist,  feminist, and eccentric, she was a friend of John Gay and Alexander Pope,  who later turned against and satirized her.

Born  into the minor nobility, Montaigne received an excellent Classical educa�  tion (speaking only Latin up to age 6) before studying law and serving  as counselor at the Bordeaux Parliament. There he met the lawyer Eti�  enne de La Boetie, with whom he formed an extraordinary friendship; the  void left by La Boetie�s death in 1563 likely led Montaigne to begin his  writing career.

Montale began his literary activities after World War I, cofounding a jour�  nal, writing for other journals, and serving as a library director in Flo�  rence. His first book of poems. Cuttlefish Bones (1925), expressed the  bitter pessimism of the postwar period. He was identified with Hermeticism  in the 1930s and �40s, and his works became progressively introverted  and obscure. With The Storm and Other Poems (1956) his writing showed  the increasing skill, warmth, and directness characteristic of his late  period.

A champion of civil and religious liberties, he  opposed Napoleon Ill�s policies after 1851. He wrote such historical works  as The Catholic Interest in the 19th Century (1852), The Political Future  of England (1856), and Monks of the West (1863-77).</p><p>Montana State (pop., 2000: 902,195), northwestern U.S. Bordered by  Canada and the U.S. states of North Dakota, South Dakota, Wyoming,  and Idaho, it covers 147,046 sq mi (380,849 sq km); its capital is Helena.  Montana straddles the Great Plains to the east and the Rocky Mountains  to the west. Unique among the states, its rivers flow into three of the con�  tinent�s primary watersheds: the Pacific, the Gulf of Mexico, and Hud�  son Bay. At the time of European settlement the region was inhabited by  various Indian tribes, including the Cheyenne, Blackfoot, Nez Perce, and  Crow. Most of Montana was obtained by the U.S. through the Louisiana  Purchase of 1803. The western part was disputed until 1846, when Brit�  ain relinquished its claim to the area. The Lewis and Clark Expedition  explored Montana in 1804-06. St. Mary�s Mission, established in 1841  by Roman Catholic missionaries, became the first permanent town as  Stevensville. Gold was discovered in the early 1860s; grazing of cattle  and sheep was introduced later that decade, leading to bitter battles with  the Indians, whose hunting grounds were destroyed. Montana Territory  was established in 1864. Though the U.S. troops of George Armstrong  Custer were defeated and slain at the Battle of the Little Bighorn in 1876,  the Indians ceased fighting in 1877 and were placed on reservations.  Montana became the 41st state in 1889. Vast deposits of copper were  found in the 1890s, and mining was the economic mainstay for almost a  century. The state�s economy now emphasizes tourism.</p><p>Montana, Joe in full Joseph Clifford Montana, Jr. (b. June 11,  1956, New Eagle, Pa., U.S.) U.S. football quarterback.

Playing with the San Francisco 49ers from 1979 to 1993, he led  the team to Super Bowl championships in 1982, 1985, 1989, and 1990.  He maintained one of the highest passing-completion rates in the NFL,  with a career average of 63.2. His career totals for passes completed  (3,409), yards passing (40,551), and touchdown passes (273) are among  the highest on record.

International renown came with his appear�  ance in the film Wages of Fear (1953). In Hollywood he starred opposite  Marilyn Monroe in Let�s Make Love (1960), and their romantic affair was  widely publicized. His later films included Z (1969), Jean de Florette,  and Manon of the Spring (both 1987). For most of his life he was known  as a supporter of left-wing causes.

He became known as el dios de la madera (�the god of wood�)  because of his great skill at wood carving. His output and influence over  50 years were enormous. Montanes is remembered for his wood altars  and altar figures covered with polished gold and coloured paint, which  are realistic yet idealized. His work influenced not only the sculptors and  altar makers of Spain and Latin America but also the Spanish painters of  his century.</p><p>Montanism Vman-to-.ni-zonA Heretical Christian movement founded  in ad 156 by Montanus.

The Montanists held that the Holy Spirit  was speaking through Montanus and that the Second Coming was immi�  nent. The bishops of Asia Minor excommunicated the Montanists (c. 177),  but the movement continued in the East as a separate sect; it also flour�  ished in Carthage, where its most illustrious convert was Tertullian.

In 1756 he was placed in command of French troops in North  America, but his commission excluded most military resources in Canada.  He forced the British to surrender their post at Oswego and captured Fort  William Henry (1757). At the Battle of Ticonderoga (1758), he repulsed  an attack by 15,000 British troops with a force of just 3,800 men. Pro�  moted to lieutenant general, he received authority over military affairs in  Canada. In 1759 a British force of 8,500 troops under Gen.

The republic�s name (�Black Mountain�) refers  to its ancient stronghold near the Adriatic Sea, Mount Lovcen, which rises  to 5,738 ft (1,749 m). Montenegro�s landscape ranges from arid hills to  forests and fertile valleys. The majority of its population are Montene�  grins who follow the Eastern Orthodox Church; there are sizable Muslim  and Albanian minorities. Under the Roman Empire the region was part  of the province of Illyricum. Settled by Slavs in the 7th century, it was  incorporated in the Serbian empire in the late 12th century. It retained its  independence following the defeat of the Serbians by the Ottoman Empire  in 1389 at the Battle of Kosovo. Often at war with the Ottomans and  Albanians, it began an alliance with Russia early in the 18th century. In  the Balkan Wars of 1912-13, it cooperated against the Ottoman Empire.  It supported Serbia during and after World War I. It was then absorbed  into Serbia; the union became part of the Kingdom of Serbs, Croats, and  Slovenes (from 1929, Yugoslavia). During World War II Montenegro was  occupied by the Italians and was the scene of heavy fighting. In 1946 the  federal constitution of the new Yugoslavia made Montenegro one of Yugo�  slavia�s six nominally autonomous federated units. In 1992, one year after  the breakup of Yugoslavia, Montenegro and Serbia combined as the new  Federal Republic of Yugoslavia. In 2003, following agitation for indepen�  dence in Montenegro, the Serbian, Montenegrin, and Yugoslav parlia�  ments ratified a new constitutional agreement that maintained the  federation; the accord renamed the country Serbia and Montenegro and  gave Montenegro significant autonomy over its own affairs.</p><p>Monterrey City (pop., 2000: 1,110,997), capital of Nuevo Leon state,  northern Mexico.

His satirical Persian Letters (1721) was hugely successful. From  1726 he traveled widely to study social and political institutions. His  magnum opus, the enormous The Spirit of the Laws (1750), contained an  original classification of governments by their manner of conducting  policy, an argument for the separation of the legislative, judicial, and  executive powers, and a celebrated but less influential theory of the politi�  cal influence of climate. The work profoundly influenced European and  American political thought and was relied on by the framers of the U.S.  Constitution.

Montessori took a degree in medicine (1894) and worked in a  clinic for retarded children before going on to teach at the University of  Rome. In 1907 she opened her first children�s school, and for the next 40  years she traveled throughout Europe, India, and the U.S., lecturing, writ�  ing, and setting up Montessori schools. Today there are hundreds of such  schools in the U.S. and Canada alone; their principal focus is on preschool  education, but some provide elementary education to grade 6. The Mont�  essori system is based on belief in children�s creative potential, their drive  to learn, and their right to be treated as individuals.

He visited the court of the Gonza-  gas in Mantua, and his next book (1592) shows freer use of dissonance  and close coordination of music and words. He married in 1599 and settled  in Mantua. Attacked in 1600 for the even freer dissonance in his newest  works, he replied that music now had two �practices,� the stricter first  practice for sacred works and the more expressive second practice for  secular music. It was his first opera, Orfeo, performed in 1607, that finally  established him as a composer of large-scale music rather than of exquis�  ite miniature works. In 1610 he completed his great Vespers. Having long</p><p>tried to obtain his release from Mantua, he was finally granted it in 1612,  and the next year he was put in charge of music at San Marco Basilica,  Venice. After the first opera house opened in Venice (1637), he wrote his  last three operas, including II ritorno d�Ulisse in patria (1640) and the  remarkable Incoronazione di Poppea (1643).

In  1502 he inherited from his uncle an empire of five to six million people  that stretched from present-day Mexico to Nicaragua. Aztec belief in the  prophesied return of the god Quetzalcoatl, whose description the con�  quistador Hernan Cortes resembled, contributed to his downfall. Cortes,  who had made alliances with tribes eager to be rid of Aztec domination,  held Montezuma prisoner in Tenochtitlan, and he died in custody.</p><p>Montezuma Castle National Monument National monument,  central Arizona, U.S. Situated in the Verde River valley, it occupies an  area of 2.6 sq mi (6.7 sq km). Declared a national monument in 1906, it  is the site of the country�s best-preserved pre-Columbian Pueblo Indian  cliff dwellings. The �castle� is a five-story, 20-room adobe brick struc�  ture, dating from c. ad 1100, built into the cliff face about 80 ft (24 m)  above the valley floor.

From 1209 he led  a Crusade against the Cathari heretics, and he became governor of the  lands he conquered in southern France. The fourth Lateran Council gave  him Toulouse (1215), but Raymond VI, count of Toulouse, refused to accept  defeat, and Montfort was killed while besieging the city. His eldest son  ceded the Montfort lands in southern France to King Louis VIII.</p><p>Montfort, Simon de later Earl of Leicester (b. c. 1208, Montfort,  Ile-de-France, France�d.

His mar�  riage to Henry Ill�s sister (1238) offended the barons and led to his tem�  porary exile. Simon distinguished himself on a Crusade to the Holy Land  (1240-42) and joined Henry�s failed invasion of France (1242). Sent to  pacify Gascony (1248), he was censured for his harsh methods there and  recalled. He joined the other leading barons in forcing Henry to accept  the Provisions of Oxford. When Louis IX annulled the Provisions, Simon  defeated and captured Henry (1264) and summoned (1265) what became  the beginning of the modern Parliament. He governed England for less  than a year before being defeated and killed by Henry�s son Edward.</p><p>Montgolfier \mo n -gol-'fya\, Joseph-Michel; and Montgolfier,  Jacques-Etienne (respectively b.

About  1717 the French built Fort Toulouse on the river above the present site of  Montgomery. The city was founded in 1819 and named for Gen. Richard  Montgomery; it became the state capital in 1846. In 1861, during the  American Civil War, it served briefly as the capital of the Confederacy; it  was captured by Union troops in 1865. It was a centre of the civil rights  movement, notably the protests organized by Martin Luther King, Jr. Located  southeast of Birmingham, it serves as the commercial centre of an agricul�  tural region, trading in cotton and livestock and producing fertilizer. It is  the seat of Alabama State University and several other institutions of  higher education.</p><p>Montgomery (of Alamein), Bernard Law Montgomery, 1 st  Viscount (b.

Educated at  Sandhurst, he distinguished himself in World War I and remained in the  army, becoming known as a tough and efficient leader. In World War II  he commanded the British army in the North Africa Campaign and forced  the German retreat from Egypt after the Battle of El Alamein (1942). He  commanded troops in the Allied invasion of Sicily and Italy (1943) and  in the Normandy Campaign, leading the British-Canadian army group  across northern France and into northern Germany. Promoted to field  marshal, he became chief of the imperial staff (1946-48) and later deputy  commander of NATO (1951-58).

He began playing guitar in his teens, and his principal early  inspiration was the late-swing guitarist Charlie Christian. Montgomery was  a member of Lionel Hampton�s band (1948-50) before forming a small  group with his brothers. His finest recordings are small-group efforts made  after 1959, although he achieved commercial success using accompany�  ing orchestras in the 1960s. His unconventional technique, using his  thumb rather than a plectrum, made possible his frequent use of octaves  and chords in solos. He was probably the most influential guitar impro�  viser in modem jazz.</p><p>Montgomery Ward &amp; Co, Former U.S. retail merchandising com�  pany.

It occupies about one-third of lie de Montreal (Mon�  treal Island), near the confluence of the Ottawa and St. Lawrence rivers.  The metropolitan area encompasses Montreal and other islands, as well  as both shores of the St. Lawrence. It is built on the slopes of a moun�  tain, Mont-Royal, from which the city�s name is derived. English and  French are spoken throughout the city, which is the chief centre of French-  Canadian industry and culture. The site was occupied by the Huron Indian  settlement of Hochelaga when visited by French explorer Jacques Cartier  in 1535. The first European settlement was founded by the French in 1642  and was given the name Ville-Marie de Montreal. Rapid colonization  based on the fur trade began in the first half of the 18th century, and the  city soon grew beyond its walls. It surrendered to British forces in 1760  and, with all of New France, became part of the British North American  empire in 1763. Montreal served as the capital of Canada from 1844 to  1849. It is one of Canada�s chief ports for both oceangoing and inland  shipping. It is Canada�s second-largest city and a major cultural centre,  with a complex of theatre and concert halls and several museums.

Situated in the eastern Caribbean Sea, it occupies an area of  40 sq mi (102 sq km); it is 11 mi (18 km) long and 7 mi (11 km) wide.  It was visited and named by Christopher Columbus in 1493 and was colo�  nized by the British and Irish in 1632. France later held it briefly, but  from 1783 it remained British. Its colonial economy was based on cotton  and sugar plantations that used African slave labour. It was part of the  colony of Leeward Islands from 1871 to 1956 and then of the Federation  of the West Indies from 1958 to 1962. It was rebuilt after a devastating  hurricane in 1989. A major eruption of the Soufriere Hills volcano in 1996  led to the evacuation of the southern half of the island and the abandon�  ment of its capital, Plymouth. By 1998 more than two-thirds of its mid-  1990s population had left the island.</p><p>Monty Python('s Flying Circus) British comedy troupe.

He gave up business in 1860 and engaged in  missionary work with the YMCA (1861-73). He founded Moody Church  and preached in the slums, emphasizing literal interpretation of the Bible  and the need to prepare for the Second Coming. In 1870 he teamed up  with the hymn writer Ira D.

It is less than one-  third the size of Earth (diameter about 2,160 mi, or 3,476 km, at its equa�  tor), about one-eightieth as massive, and about two-thirds as dense. Its  surface gravity is about one-sixth that of Earth, and its gravitational pull  is largely responsible for Earth�s tides. The Moon shines by reflected sun�  light, but its albedo is only 7.3%. It rotates on its axis in about 29.5 days,  in exactly the time it takes to orbit Earth, and it therefore always presents  the same face to Earth. However, that face is lit by the Sun at different  angles as the Moon revolves around Earth, causing it to display different  phases over the month, from new to full. Most astronomers believe the  Moon formed from a cloud of fragments ejected into Earth orbit when a  MARS-sized body struck the proto-Earth early in the solar system�s his�  tory. Its surface has been studied by telescope since Galileo first observed  it in 1609 and firsthand by a total of 12 U.S. astronauts during the six  successful lunar landing missions of the Apollo program. The dominant  process affecting the surface has been impacts, both from micrometeorite  bombardment, which grinds rock fragments into fine dust, and from mete�  orite strikes, which produced the craters profusely scattered over its sur�  face mostly early in its history, over four billion years ago. The maria (see  mare) are huge, ancient lava flows. In the late 1990s unmanned spacecraft  found possible signs of water ice near the Moon�s poles.

After  being imprisoned by North Korean authorities, he escaped or was released  and went to South Korea, where he founded the Unification Church in 1954  and built a multimillion-dollar business empire. In 1973 he moved his  headquarters to Tarrytown, N.Y., U.S., where he became the focus of con�  troversies over fund-raising techniques, tax evasion, and the indoctrina�  tion of followers (popularly called Moonies). In 1982 Moon was  convicted of tax evasion, sentenced to 18 months in prison, and fined  $25,000. He has also suffered from a damaging expose by his daughter-  in-law.

He  is best known for his first novel, The Lonely Passion of Judith Hearne  (1955; film, 1987), about an aging spinster whose pretensions to gentil�  ity are gradually dissolved in alcoholism. His later novels include The  Luck of Ginger Coffey (1960), The Emperor of Ice Cream (1965), The  Doctor�s Wife (1976), and The Magician�s Wife (1998).

Oct.  24, 1958, Cambridge, Cambridgeshire) British philosopher, one of the  founders of analytic philosophy. While a fellow at the University of Cam�  bridge (1898-1904), he published two influential papers, �The Nature of  Judgment� (1899) and �The Refutation of Idealism� (1903), that did much  to break the hold of absolute idealism on British philosophy. Also published  during this period was his major ethical work, Principia Ethica (1903), in  which he argued that �good� is a simple and unanalyzable quality that is  knowable by direct apprehension. His intuitionism was the dominant meta-  ethical position in Britain for the next 30 years, and it exerted considerable  influence within the Bloomsbury group of artists and intellectuals. In epis�  temology, Moore is remembered for his �common sense� philosophy,  according to which human beings know to be true many propositions about  themselves and the world that are inconsistent with idealist and skeptical  doctrines (e.g., �The Earth has existed for many years�). His general posi�  tion was that, because no argument for idealism or skepticism is as certain  as the commonsense view, idealism and skepticism can be rejected out of  hand. He was professor of philosophy at Cambridge from 1925 to 1939.  From 1921 to 1947 he edited the journal Mind.</p><p>Moore, Henry (b. July 30, 1898, Castleford, Eng.�d.

The son of a coal  miner, he was enabled to study at the Royal College of Art by a rehabili�  tation grant after being wounded in World War I. His early works were  strongly influenced by the Mayan sculpture he saw in a Paris museum.  From c. 1931 on he experimented with abstract art, combining abstract  shapes with the human figure and at times leaving the human figure behind</p><p>altogether. When materials grew scarce during World War II, he concen�  trated on drawings of Londoners sheltering from bombs in Underground  stations. Commissions for a Madonna and Child and a family group  turned his style from abstraction to the more humanistic approach that  became the basis of his international reputation. He returned to experi�  mentation in the 1950s with angular, pierced standing figures in bronze.  Much of his work is monumental, and he is particularly well known for  a series of reclining nudes. Among his major commissions were sculp�  tures for UNESCO�s Paris headquarters (1957-58), Lincoln Center  (1963-65), and the National Gallery of Art (1978).</p><p>Moore, Marianne (Craig) (b.

In her highly disciplined  poems she distilled moral and intel�  lectual insights from close observa�  tion of objective detail, especially in  the animal world, often in innovative  stanzaic forms. In her much-  anthologized �Poetry� (1921) she  called for poems that present �imagi�  nary gardens with real toads in them.� In her late years the winningly  eccentric Moore, in her cape and tricomered hat, became an icon of  sprightly gentility.</p><p>Moore, Mary Tyler (b.

She achieved even  greater success as the star of The Mary Tyler Moore Show (1970-77; four  Emmy Awards), which became the most popular situation comedy of the  1970s. She also won an Emmy for her role in the television miniseries  Stolen Babies (1993). Her films include Ordinary People (1980) and Flirt�  ing with Disaster (1996).</p><p>Moore, Stanford (b. Sept. 4, 1913, Chicago, Ill., U.S.�d. Aug. 23,  1982, New York, N.Y.) U.S. biochemist. He shared a 1972 Nobel Prize  with Christian Anfinsen (1916-95) and William Stein (1911-80) for  research on the molecular structures of proteins. He is best known for his  applications of chromatography to the analysis of amino acids and peptides  obtained from proteins and biological fluids and for the use of those  analyses in determining the structure of the enzyme ribonuclease.</p><p>Moore, Thomas (b. May 28, 1779, Dublin, Ire.�d. Feb. 25, 1852,  Wiltshire, Eng.) Irish poet, satirist, composer, and singer. Moore gradu�  ated from Trinity College and studied law in London, where he became  a close friend of Lord Byron and Percy Bysshe Shelley. His collections Irish  Melodies and National Airs (1807-34) consist of 130 original poems set  to folk melodies, including �The Minstrel Boy,� �Believe Me, if All Those  Endearing Young Charms,� and �The Last Rose of Summer.� Performed  by Moore for London�s aristocracy, they aroused sympathy and support  for Irish nationalists. His reputation among his contemporaries rivaled that  of Byron and Walter Scott. His poem Lalla Rookh (1817), a romantic  Oriental fantasy, became the most translated poem of its time. In 1824 he  was entrusted with Byron�s memoirs; he burned them, presumably to pro�  tect Byron. He later published biographies of Byron and others, as well  as a History of Ireland (1827).</p><p>moorhen or common gallinule Bird of the migratory gallinule spe�  cies ( Gallinula chloropus, family Rallidae) of Europe, Africa, and east�  ern North America.

The U.S. psychologist Lawrence  Kohlberg hypothesized that people�s development of moral standards  passes through several levels. At the early level, that of preconventional  moral reasoning, the child uses external and physical events (such as  pleasure or pain) as the source for moral decisions; his standards are based  strictly on what will avoid punishment or bring pleasure. At the interme�  diate level, that of conventional moral reasoning, the child or adolescent  views moral standards as a way of maintaining the approval of authority  figures, chiefly his parents, and acts in accordance with their precepts. At  the third level, that of postconventional moral reasoning, the adult bases  his moral standards on principles that he himself has evaluated and accepts  as inherently valid, regardless of society�s opinion. Beginning in the  1970s Kohlberg�s work was criticized by psychologists and philosophers  influenced by feminism. According to Carol Gilligan, Kohlberg�s stages  are inherently sexist, because they equate moral maturity with an orien�  tation toward moral problems that is socially instilled in males but not in  females. Whereas the male �ethic of rights and justice� treats morality in  terms of abstract principles and conceives of moral agents as essentially  autonomous, acting independently of their social situations according to  general rules, the female �ethic of care� treats morality in terms of con�  crete bonds to particular individuals based on feelings of care and respon�</p><p>sibility and conceives of moral agents as connected and interdependent  through their feelings of care and responsibility for each other.</p><p>Morales \mo-'ra-las\ / Luis de (b. c. 1509, Badajoz, Spain�d.

He  is considered Spain�s greatest Man�  nerist painter and is known especially  for his emotional religious paintings.</p><p>He always worked on panels, often  depicting such subjects as the Ecce  Homo, the Pieta, and the Virgin and  Child. His paintings show the influ�  ence of Leonardo da Vinci and Raphael  and are marked by detailed execu�  tion and the anguished asceticism of  16th-century Spain.</p><p>morality play Allegorical drama  of 15th-16th-century Europe. The  plays� characters personified moral  qualities (such as charity or vice) or  abstractions (such as death or youth).</p><p>One of the main types of vernacular  drama of its time, it provided a tran�  sition from liturgical drama to profes�  sional secular drama. The plays were  short works, usually performed by  semiprofessional acting troupes that relied on public support. Everyman  (c. 1495), featuring Everyman�s summons by Death and his journey to  the grave, is considered the greatest morality play. See also miracle play;  MYSTERY PLAY.</p><p>Morandi Xmo-'ran-deV Giorgio (b. July 20, 1890, Bologna, Italy�d.  June 18, 1964, Bologna) Italian painter and etcher. He first exhibited his  paintings with the Futurists and was closely associated with the Metaphysi�  cal painters, but he is identified with neither school. He repeatedly returned  to the subject matter of simple, geometric still lifes of bottles, jars, and  boxes; by returning to the same subject matter, he was able to move past  content to an exploration of pure form (i.e., line, colour, shape). His con�  templative approach gave his landscapes and still lifes a delicacy of tone  and subtlety of design. As instructor of etching at Bologna�s Academy of  Fine Arts (1930-56), he had a profound influence on Italian graphic artists.</p><p>Morava River \'mo-ra-va\ German March \'mark\ River, eastern  Czech Republic.

It gives its name to Moravia, the area  around it.</p><p>Morava River River, Serbia, Serbia and Montenegro. Formed by the  confluence of the South (Juzna) Morava and West (Zapadna) Morava riv�  ers, it flows north to enter the Danube River, after a course of 137 mi (221  km). The total area of the Morava River basin is 14,457 sq mi (37,444 sq  km), corresponding almost to the political definition of Serbia.</p><p>Moravia \ma-'ra-ve-9\ Region, central Europe. Bounded by Bohemia,  Silesia, Slovakia, and northeastern Austria and crossed by the Morava  River, it was inhabited from the 4th century bc. It was dominated by the  Avars in the 6th and 7th centuries ad and later settled by Slavic tribes,  and in the 9th century it became the state of Great Moravia and included  Bohemia as well as parts of modem Poland and Hungary. It was destroyed  by the Magyars in 906. In 1526 it came under Habsburg rule. After the  Revolution of 1848 Moravia became an Austrian crown land with its  capital at Brno. In 1918 it was incorporated into the new state of Czecho�  slovakia. Germany annexed parts of it in 1938; after World War II they  were restored to Czechoslovakia.

It traces its origins to the Unity of Brethren, a 15th-century Hussite  movement in Bohemia and Moravia. The original Brethren movement was  eroded by persecution, but it was renewed in 1722 at Hermhut, a theo�  cratic community established in Saxony. In America the Moravians  founded Bethlehem, Pa. (1740), and several other settlements, and carried  out missionary work among the Indians. The Moravians ordain bishops  but are governed by synods of elected representatives; they are guided by  the Bible as their only rule of faith and worship.</p><p>moray Vmo-'ra, 'm6r-,a\ Any of about 80 species (family Muraenidae)  of shallow-water eels inhabiting all  tropical and subtropical seas. They  live among reefs and rocks and hide  in crevices. Their skin is thick,  smooth, scaleless, and usually viv�  idly marked or coloured. Most spe�  cies lack pectoral fins. Morays have  a wide mouth and strong, sharp teeth  for seizing and holding prey (chiefly  other fishes). They attack humans  only when disturbed. Most species  are less than 5 ft (1.5 m) long, but  Thyrsoidea macrurus, of the Pacific  Ocean, may grow to more than 11 ft (3.5 m). Morays are sometimes eaten,  but their flesh may be toxic and can cause illness or death if consumed.</p><p>Moray Firth Vmsr-eV Inlet of the North Sea, northeastern Scotland.

He served as an undersheriff of London (1510-18) and endeared  himself to Londoners as a fair judge and consultant. He wrote the notable  History of King Richard III (1513-18) and the renowned Utopia (1516),  which was an immediate success with humanists, including Desiderius  Erasmus. In 1517 More was named to the king�s council, and he became  Henry VIII�s secretary and confidant. In 1523 he was elected speaker of  the House of Commons. He wrote A Dialogue Concerning Heresies  (1529) to refute heretical writings. After the fall of Cardinal Wolsey  (1529), More succeeded him as lord chancellor, but he resigned in 1532  when he could not affirm Henry�s divorce from Catherine. He also refused  to accept the Act of Supremacy. In 1534 More was charged with high trea�  son and imprisoned in the Tower of London, where he wrote his Dialogue  of Comfort Against Tribulation. In 1535 he was tried and sentenced to  death by hanging, which the king commuted to beheading.</p><p>Moreau \m6-'ro\, Gustave (b. April 6, 1826, Paris, France�d.

Such works as Oedipus and the Sphinx (1864)  and Dance of Salome (1876) have often been described as decadent. He  made a number of technical experiments, including scraping his canvases;  his nonfigurative paintings, done in a loose manner with thick impasto,  have led some to call him a herald of Abstract Expressionism.</p><p>Moreau, Jeanne (b.

Though not  conventionally beautiful, she became noted for her sensuality and sophis�  tication. She starred in Moderato cantabile (1960), La notte (1961), and  Jules et Jim (1961), playing a woman loved by two men in the movie that  established her as an international star, and later in The Trial (1962), Diary  of a Chambermaid (1964), and The Bride Wore Black (1968).

Most species of Gyromitra are poisonous.</p><p>Morelia \mo-'ral-ya\ City (pop., 2000: 549,996), capital of Michoacan  state, west-central Mexico. It was founded in 1541 as Valladolid, at the  site of a Tarascan Indian settlement. It replaced Patzcuaro as the provin�  cial capital in 1582. During the Mexican wars for independence it served  briefly as the base of operations for the revolution; in 1828 its name was  changed from Valladolid to Morelia in honor of revolutionary leader Jose  Marfa Morelos. It is the commercial centre of an agricultural region. Its  educational institutions include the University of Michoacan and the Cole-  gio San Nicolas (1540), Mexico�s oldest institution of higher learning.</p><p>Morelos \mo-'ra-los\ State (pop., 2000: 1,555,296), central Mexico.

The �Jus�  tin Morgan horse,� a blend of Thoroughbred, Arabian, and other elements,  was a compact, heavily muscled, short-legged horse of great style, energy,  and endurance. Because he alone founded the breed, he is the world�s  best example of prepotency (ability to pass one�s traits to one�s offspring).  Modem Morgans are used mostly for riding. They are 14.1-15.2 hands  (57-61 in., 145-155 cm) high, weigh 900-1,100 lbs (400-500 kg), and  resemble the Arabian in conformation and endurance.</p><p>Morgan, Daniel (b. 1736, Hunterdon county, N.J.�d.

March 31, 1913, Rome, Italy) U.S. financier. The son of a fin�  ancier, he began his career as an accountant in 1857 and became an agent  for his father�s banking company in 1861. In 1871 he was named a part�  ner in the firm of Drexel, Morgan, which became the chief source of U.S.  government financing. In 1895 it became J.R Morgan and Co. In the 1880s  and �90s Morgan reorganized several major railroads, notably the Erie  Railroad and the Northern Pacific. He was instrumental in achieving rail�  road rate stability and discouraging overly chaotic competition, and he  became one of the world�s most powerful railroad magnates, controlling  about 5,000 mi (8,000 km) of railway by 1902. After the panic of 1893,  Morgan formed a syndicate to supply the U.S. Treasury�s depleted gold  reserves. He led the financial community in averting a general financial  collapse following the stock-market panic of 1907. He financed a series  of giant industrial consolidations, organizing the mergers that formed  General Electric, United States Steel Corp., and International Harvester Co.  (see Navistar International Corp.). A noted art collector, he donated many  artworks to the Metropolitan Museum of Art; his book collection and the  building that housed it became the Pierpont Morgan Library in New York  City.</p><p>Morgan, J(ohn) P(ierpont), Jr. (b. Sept. 7, 1867, Irvington, N.Y.,  U.S.�d. March 13, 1943, Boca Grande, Fla.) U.S. banker and financier.  He joined J.P. Morgan and Co. in 1892 and took control of it in 1913 on  the death of his father, J.R Morgan. In World War I he served as pur�  chasing agent in the U.S. for the British and French governments and  organized the underwriting of more than $1.5 billion in Allied bonds. He  pooled funds with other bankers in an unsuccessful attempt to prevent the  crash of 1929. The Banking Act of 1933 compelled his firm to separate  its investment-banking and commercial-banking activities. Morgan, Stan�  ley and Co. became a new investment-banking firm, while Morgan him�  self remained head of J.P. Morgan &amp; Co., which was from then on strictly  a commercial-banking firm.</p><p>Morgan, Joe in full Joseph Leonard Morgan (b. Sept. 19, 1943,  Bonham, Texas, U.S.) U.S. baseball player. Morgan was named Rookie  of the Year in 1965, his first full season with the Houston Astros. During  each of his eight seasons with the Cincinnati Reds (1972-79) he made the  All-Star team as second baseman. He was named the National League�s  Most Valuable Player in 1975 and 1976, when he led the Reds to con�  secutive World Series championships. He broke Rogers Hornsby�s record  for home runs by a second baseman, with 266 (later broken by Ryne  Sandberg with 277). In 1990 Morgan was inducted into the Baseball Hall  of Fame.</p><p>Morgan, John (b. June 10, 1735, Philadelphia, Pa., U.S.�d. Oct. 15,  1789, Philadelphia) U.S. medical educator. He studied medicine in Europe  before returning to the American colonies to found their first medical  school in 1765 at the University of Pennsylvania. As North America�s  first professor of medicine, he required a liberal education of his students  and separated medicine, surgery, and pharmacology into distinct disci�  plines, policies widely opposed by colonial physicians. He was made head  of the army�s medical system in 1775; however, the Continental Congress  did not let him organize the system and dismissed him in 1777, holding  him responsible for the war�s high death rate. Though absolved in 1779,  he never recovered, and he died an impoverished recluse.</p><p>Morgan, Julia (b. Jan. 20, 1872, San Francisco, Calif., U.S.�d. Feb.  2, 1957, San Francisco) U.S. architect. She received an engineering degree  from the University of California at Berkeley. The first female architec�  ture student at the Ecole des Beaux-Arts in Paris (1898), she later became  California�s first licensed woman architect. Morgan then commenced 40  years of architectural work that resulted in some 800 buildings, most of  them in California, particularly in San Francisco. She opened her own  architectural office in 1904, and the devastation of the San Francisco  earthquake of 1906 provided her with the opportunity to design hundreds  of homes and many churches, office buildings, and educational buildings  in the Bay area. She is best remembered for designing William Randolph  Hearst�s private castle at San Simeon (1919-38).</p><p>Morgan, Lewis Henry (b. Nov. 21, 1818, near Aurora, N.Y.,  U.S.�d. Dec. 17, 1881, Rochester, N.Y.) U.S. ethnologist and a princi�  pal founder of scientific anthropology. Morgan developed a deep interest</p><p>in the American Indians and in 1846 was eventually adopted by the Sen�  eca. His Systems of Consanguinity and Affinity of the Human Family  (1871) was a world survey of kinship systems that sought to establish con�  nections between cultures and particularly to establish the Asiatic origin  of the American Indians. This work led to a comprehensive theory of  sociocultural evolution, set forth in Ancient Society (1877). He claimed  that advances in social organization arose primarily from changes in food  production and that society had progressed from a hunting-and-gathering  stage (�savagery�) to one of settled agriculture (�barbarism�) to modem  �civilization.� This theory, with the related theory that society originated  in a state of sexual promiscuity and advanced through various forms of  family life before culminating in monogamy, is now obsolete. For many  years, however, Morgan was the dean of American anthropology, and his  pioneering ideas influenced the theories of Karl Marx and Friedrich Engels,  among others.</p><p>Morgan, Thomas Hunt (b. Sept. 25, 1866, Lexington, Ky., U.S.�d.  Dec. 4, 1945, Pasadena, Calif.) U.S. zoologist and geneticist. He received  his doctorate from Johns Hopkins University. As a professor at Colum�  bia University (1904-28) and California Institute of Technology (1928�  45), he conducted important research on heredity. Like many of his  contemporaries, Morgan found Charles Darwin�s theory of natural selec�  tion implausible because it could not be tested experimentally, and he  objected to Mendelian and chromosome theories, arguing that no single  chromosome could carry specific hereditary traits. His opinion changed  as a result of his studies of Drosophila. He developed the hypothesis of  sex-linked traits. He adopted the term gene and concluded that genes were  possibly arranged in a linear fashion on chromosomes. He was awarded  the Nobel Prize in 1933.

His small literary output includes the novel Maler Nolten (1832), fairy  tales, and Mozart on the Way to Prague (1856), a humorous examination  of the problems of artists in a world uncongenial to art. His best works  are his exquisite lyrics, notably the �Peregrina� poems, which immortal�  ize a youthful love, and sonnets to a onetime betrothed; many were set  to music by Hugo Wolf.</p><p>Morison, Samuel Eliot (b. July 9,1887, Boston, Mass., U.S.�d. May  15, 1976, Boston) U.S. biographer and historian. He taught at Harvard  University for 40 years. To give authenticity to his writings on maritime  history, he undertook numerous voyages and during wartime served on  12 ships as a commissioned officer in the U.S. Naval Reserve. His works  include Admiral of the Ocean Sea (1942, Pulitzer Prize), on Christopher  Columbus; John Paul Jones (1959, Pulitzer Prize); the monumental His�  tory of U.S. Naval Operations in World War II, 15 vol. (1947-62); and  The Oxford History of the American People (1965).</p><p>Morison, Stanley (b. May 6, 1889, Wanstead, Essex, Eng.�d.

He served as editor of the influential typographic  journal The Fleuron (1926-30). He worked for The Times (London) in  various capacities, including editor of The Times Literary Supplement  (1929-60). He is best known as the designer of Times New Roman, which  was adopted as The Times 's basic typeface in 1932, and went on to  become the most successful new typeface of the 20th century.</p><p>Morisot \m6-re-'zo\/ Berthe (b. Jan. 14, 1841, Bourges, France�d.  March 2, 1895, Paris) French painter and printmaker. Granddaughter of  Jean-Honore Fragonard, she, studied with Camille Corot, but the major  influence over her work was Edouard Manet, whose brother she later mar�  ried. She exhibited regularly with the Impressionists. None of her exhibits  proved commercially successful, but she outsold Claude Monet, Pierre-  Auguste Renoir, and Alfred Sisley. Her colouring was delicate and subtle,  often with a subdued emerald glow, and her subjects were often members  of her family. She is best known for her extremely loose brushwork and  for the sensitivity she brought to her female subjects.</p><p>Morita \m6-'re-t3\, Akio (b. Jan. 26, 1921, Nagoya, Japan�d. Oct. 3,  1999, Tokyo) Japanese entrepreneur, cofounder of Sony Corp. The son of  an old sake-brewing family, Morita was trained as a physicist. In 1946 he  and Ibuka Masaru cofounded the Tokyo Telecommunications Engineer�  ing Corp., which changed its name to Sony Corp. in 1958. Primarily  responsible for finances and marketing, Morita adopted U.S. advertising  techniques and established Sony�s first U.S. plant in 1972. He became  chief executive officer in 1971 and chairman of the board in 1976, in  which post he served until 1994. Under his direction Sony became a  world-renowned manufacturer of consumer electronics.</p><p>Morley (of Blackburn), John Morley, Viscount (b. Dec. 24,  1838, Blackburn, Eng.�d. Sept. 23, 1923, Wimbledon, London) English  politician and historian. He worked as a journalist in London from 1860,  mainly as editor of the liberal Fortnightly Review (1867-82). A supporter  of William E. Gladstone, Morley served in the House of Commons (1883�  95, 1896-1908). As chief secretary for Ireland (1886, 1892-95), he helped  prepare the Irish Home Rule bills. As secretary for India (1905-10), he  brought elected Indian representation into the government. He also wrote  acclaimed historical works, including biographies of Gladstone, Voltaire,  Jean-Jacques Rousseau, and Oliver Cromwell.</p><p>Morley, Thomas (b. 1557/58, Norwich, Norfolk, Eng.�d. October  1602, London) English composer, organist, and music theorist. He was  educated at Oxford and studied with William Byrd. Though he composed  a number of anthems and psalms, he is best known for his secular songs,  including those published in the First Booke of Ayres (1600), and for the  treatise A Plaine and Easie Introduction to Practicall Musick (1597). By  editing and printing several anthologies of Italian music (often reworked),  he was instrumental in bringing the Italian madrigal to England. He also  edited The Triumphes of Oriana (published 1603), the most significant  collection of English madrigals.</p><p>Mormon Member of the Church of Jesus Christ of Latter-day Saints or  of a sect closely related to it (e.g., the Community of Christ). The Mormon  religion was founded by Joseph Smith, who claimed to have received an  angelic vision telling him of the location of golden plates containing  God�s revelation; this he published in 1830 as the Book of Mormon. Smith  and his followers accepted the Bible as well as the Mormon sacred scrip�  tures but diverged significantly from orthodox Christianity, especially in  their assertion that God exists in three distinct entities as Father, Son, and  Holy Spirit. Mormons also believe that faithful members of the church  will inherit eternal life as gods. Other unique doctrines include the belief  in preexisting souls waiting to be born and in salvation of the dead through  retroactive baptism. The church became notorious for its practice of  polygamy, though it was officially sanctioned only between 1852 and 1890.  Smith and his followers migrated from Palmyra, N.Y., to Ohio, Missouri,  and finally Illinois, where Smith was killed by a mob in 1844. In 1846-  47, under Brigham Young, the Mormons made a 1,100-mi (1,800-km) trek  to Utah, where they founded Salt Lake City. In the early 21st century, the  church had a worldwide membership of nearly 10 million, swelled yearly  by the missionary work that church members, both men and women, are  encouraged to perform.</p><p>Mormon, Book of Holy scripture of the Mormons, supplemental to  the Bible. First published in 1830, it is held by all branches of Mormon-  ism to be a divinely inspired work translated by the founder of their reli�  gion, Joseph Smith. It relates the history of a tribe of Hebrews who migrated</p><p>from Jerusalem to America c. 600 bc. They eventually split into two  groups: the Lamanites, who were ancestors of the American Indians; and  the Nephites, who were instructed by Jesus before being destroyed by the  Lamanites. The prophet Mormon recorded their history on gold tablets,  which were buried and remained hidden for centuries. Moroni, Mormon�s  son, appeared to Smith in angelic form and revealed their location.</p><p>morning-glory family Family Convolvulaceae, composed of about  1,400 species of flowering plants in 50 genera, widely cultivated for their  colourful, funnel-shaped flowers. Most are twining and erect herbaceous  plants; a few are woody vines, trees, or shrubs. The family is widespread  in both tropical and temperate areas. Most popular morning glories are of  the genus Ipomoea, as is the sweet potato. Several species of bindweeds are  agricultural pests. The seeds of two species, Rivea corymbosa and I. vio-  lacea, contain hallucinogenic compounds of historical interest.</p><p>Morny \m6r-'ne\, Charles-Auguste-Louis-Joseph, duke de</p><p>(b. Oct. 21, 1811, Paris, France�d. March 10, 1865, Paris) French poli�  tician. Half brother of Louis-Napoleon (later Napoleon III), Morny devoted  himself to Parisian society and to making a fortune before serving in the  Chamber of Deputies (1842-48, 1849). Appointed minister of the interior  in 1851, he organized the plebiscite that made Louis-Napoleon dictator.  As president of the legislature (1856-65), he tried unsuccessfully to per�  suade Napoleon III to give France more liberty.</p><p>Moro Any member of several Muslim peoples living in the southern  Philippines. The Moros, who constitute about 5% of the Philippine popu�  lation, are not ethnically different from other Filipinos, but, with a sepa�  rate Islamic faith and local cultures, they have been the object of prejudice  and neglect. They have a centuries-long history of conflict with ruling  powers: first with Roman Catholic Spanish colonialists (16th-19th cen�  tury), later with U.S. occupation troops, and finally with the independent  Philippine government. Although the Moro National Liberation Front�  which espoused Moro separatism and led a violent insurgency in the late  1960s and �70s�split into factions at the end of the 1970s, the insurgency  continued. Provisions for the expansion of the Autonomous Region of  Muslim Mindanao, established in the late 1980s, were included in a 1996  treaty, but some separatists continue to hold out for complete indepen�  dence.</p><p>Moro, Aldo (b. Sept. 23, 1916, Maglie, Italy�d. May 9, 1978, near or  in Rome) Italian politician and premier of Italy (1963-64,1964-66, 1966-  68, 1974-76, 1976). A professor of law at the University of Bari, he was  elected to the legislature in 1946. He served in several cabinet posts, then  became secretary of the Christian Democrat Party (1959-63). As premier  of Italy, he included socialists in his coalition governments. In 1976 he  became president of the Christian Democrats and remained influential in  Italian politics. In 1978 he was kidnapped in Rome by the Red Brigades;  after the government refused to release Red Brigades members on trial  in Turin, he was murdered by his captors.</p><p>Moroccan crises (1905-06, 1911) Two European incidents centring  on Germany�s attempt to block France�s control of Morocco and to restrict  French power. While visiting Tangier in 1905, the German emperor Wil�  liam II issued a statement of support for Moroccan independence, which  caused international panic. The crisis was resolved at the Algeciras Con�  ference (1906), which recognized France�s special political interests in  Morocco. The second crisis occurred in 1911 when a German gunboat  arrived in Agadir, ostensibly to protect German economic interests dur�  ing a local uprising. The French objected and made preparations for war,  as did Britain, but a settlement was negotiated that gave France rights to  a protectorship over Morocco. In return, Germany acquired part of the  French Congo.</p><p>Morocco officially Kingdom of Morocco Country, North Africa.  Area: 177,117 sq mi (458,730 sq km). Population (2005 est.): 31,478,000.  Capital: Rabat. Arabized Berbers (Amazigh) are the country�s largest eth-  nolinguistic group; there are French, Spanish, and Bedouin minorities.  Languages: Arabic (official), Berber, French. Religion: Islam (official;  mostly Sunni). Currency: dirham. Morocco is a mountainous country with  an average elevation of 2,600 ft (800 m) above sea level. A mountain chain  known as the Rif runs along the northern coast; the Atlas Mountains rise  in the country�s centre and include Mount Toubkal (13,665 ft [4,165 m]),  Morocco�s highest peak. The area is a zone of severe seismic activity, and  earthquakes are frequent. Fertile lowlands support agriculture; major  crops include barley, wheat, and sugar beets. Morocco is one of the  world�s largest suppliers of phosphate. Its industrial centre is Casablanca,</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1296 I Moroni &#x25BA; Morris</p><p>L_</p><p>N</p><p>'15�</p><empty-line/><p>SPAIN</p><p>PORTUGAL</p><p>-J</p><p>ofvV</p><p>/Gibraltar (u.k.)</p><p>CEUTA(SPAIN)</p><p>*Tetouan</p><p>ATLANTIC</p><p>OCEAN</p><p>Tangier^</p><p>Lara^he� 11 * .

It is a constitutional mon�  archy with two legislative houses; its chief  of state and head of government is the king,  assisted by the prime minister. The Berbers  entered Morocco near the end of the 2nd</p><p>millennium bc. Phoenicians established trading posts along the Mediter�  ranean coast during the 12th century bc, and Carthage had settlements  along the Atlantic coast in the 5th century bc. After the fall of Carthage,  the region�s leaders became loyal allies of Rome, and in ad 42 it was  annexed by the Romans as part of the province of Mauretania. It was  invaded by Muslims in the 7th century. The Almoravid dynasty conquered  it and the Muslim areas of Spain in the mid-11th century; the Almohad  dynasty overthrew the Almoravids in the 12th century and in turn were  conquered by the Marin id dynasty in the 13th century. After the fall of the  Marinids in the mid-15th century, the Sa'di dynasty ruled for a century,  beginning c. 1550. Attacks by Barbary Coast pirates compelled Europe�  ans to enter the area; the French fought Morocco over the boundary with  Algeria, Europeans obtained trading rights in 1856, and the Spanish seized  part of Moroccan territory in 1859. Morocco was a French protectorate  from 1912 until its independence in 1956. In the 1970s it reasserted claim  to the Spanish Sahara (see Western Sahara), and in 1976 Spanish troops  withdrew from the region, leaving behind the Algerian-supported Saharan  guerrillas of the Polisario movement. Relations with Mauritania and Alge�  ria deteriorated, and fighting over the region continued. Attempts at  mediation have been made by the international community.</p><p>Moroni Town (pop., 1995: 340,168), capital of the Comoros Islands,  located on Grande Comore (Njazidja) island in the Indian Ocean. Founded  by Arabic-speaking settlers, it is the largest settlement of the Comoros  and has served as the capital since 1958. The port of Moroni consists of  a small quay in a natural cove. The town retains an Arabic character and  has several mosques, including Chiounda, a pilgrimage centre.</p><p>morpheme In linguistics, the smallest grammatical unit of speech. It  may be an entire word (cat) or an element of a word (re- and -ed in reap�  peared). In so-called isolating languages, like Vietnamese, each word  contains a single morpheme; in languages such as English, words often  contain multiple morphemes. The study of morphemes is included in  MORPHOLOGY.</p><p>Morpheus In Greek and Roman mythology, the god of dreams. He was  one of the sons of Hypnos (Somnus), god of sleep. Morpheus sent human  shapes of all kinds to the dreamer, while his brothers Phobetor and Phan-  tasus sent the forms of animals and inanimate objects.</p><p>morphine Heterocyclic compound, narcotic analgesic alkaloid originally  isolated from opium. It is among the most powerful naturally occurring</p><p>compounds in its ability to reduce pain and distress; its calming effect  protects the system against exhaustion in traumatic shock, internal hem�  orrhage, congestive heart failure, and other debilitating conditions. Mor�  phine is usually given by injection but may be taken by mouth. Its most  serious drawback is its addictiveness; many doctors are reluctant to use  amounts adequate to relieve severe pain, even though short-term use in  such cases rarely leads to drug addiction. This remains controversial even  in terminal cases, when addiction is arguably irrelevant; another issue in  such cases is that large doses depress respiration and may thus hasten  death.</p><p>morpho Any species of New World tropical brush-footed butterflies in  the genus Morpho (family Nympha-  lidae). Microscopic ridges on the  wing scales break up and reflect  light, producing the iridescent blue  of the males of some species. The  generally duller-coloured females  have broader, less graceful wings.</p><p>The hairy larvae feed on plants and  live and pupate in a communal web.</p><p>Some species have poisonous hairs  that can cause a rash on human skin.</p><p>Morphos are raised commercially in  South America for use in jewelry,  lamp shades, pictures, and tray inlays.</p><p>Morpho butterfly (Morpho nestira).</p><p>APPEL COLOR PHOTOGRAPHY</p><p>morphology \m6r-'fa-l3-je\ In biology, the study of the size, shape,  and structure of organisms in relation to some principle or generalization.  Whereas anatomy describes the structure of organisms, morphology  explains the shapes and arrangement of parts of organisms in terms of  such general principles as evolutionary relations, function, and develop�  ment.</p><p>morphology In linguistics, the internal construction system of words  and its study. Languages vary widely in the number of morphemes a word  can have. English has many words with multiple moiphemes (e.g.,  replacement is composed of re-, place, and -ment). Many American Indian  languages have a highly complex morphology; other languages, such as  Chinese, have a simple one. Morphology includes the grammatical pro�  cesses of inflection, marking categories like person, tense, and case (e.g.,  the -s in jumps marks the third-person singular in the present tense), and  derivation, the formation of new words from existing words (e.g., accept�  able from accept).</p><p>Morrill Act See Land-Grant College Act of 1862</p><p>Morris, Gouverneur (b. Jan. 31, 1752, Morrisania house,  Manhattan�d. Nov. 6, 1816, Morrisania house) American statesman and  financial expert. He was admitted to the bar (1771) and served in the New  York Provincial Congress (1775-77) and the Continental Congress  (1778-79). He distrusted the democratic tendencies of colonists who  wanted to break with England, but his belief in independence led him to  join their ranks. As assistant superintendent of finance (1781-85), he pro�  posed the decimal coinage system that became the basis for U.S. currency.  A delegate to the Constitutional Convention, he helped write the final draft  of the Constitution of the United States. He served as minister to France  (1792-94) and as a U.S. Senator (1800-03), and he was the first chair�  man of the Erie Canal commission (1810-16).</p><p>Morris, Mark (b. Aug. 29, 1956, Seattle, Wash., U.S.) U.S. dancer and  choreographer. He formed the Mark Morris Dance Group in 1980. It was  the resident company at the Theatre Royal de la Monnaie in Brussels  (1988-91), returned to the U.S. in 1991, and made its permanent home  in Brooklyn in 2001. Known for his daring style, he has choreographed  many works for his own company as well as for opera productions and  television performances, including The Hard Nut (1991), his modernized  version of The Nutcracker.</p><p>Morris, Robert (b. Jan. 31, 1734, Liverpool, Merseyside, Eng.�d.  May 8, 1806, Philadelphia, Pa., U.S.) British-born American financier and  politician. He immigrated to join his father in Maryland in 1747 and  entered a Philadelphia mercantile firm the following year. As a member  of the Continental Congress in the American Revolution, he practically  controlled the financial operations of the war from 1776 to 1778, bor�  rowing money from the French, requisitioning from the states, and even  advancing money from his own pocket. He established the Bank of North</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Morris &#x25BA; mortar I 1297</p><p>America (1781) and served as U.S. superintendent of finance (1781-84)  under the Articles of Confederation. He was a delegate to the Annapolis  Convention and the Constitutional Convention and served in the U.S.  Senate (1789-95). After investing heavily in land speculation, he went  bankrupt and spent more than three years in a debtors� prison before his  release in 1801.</p><p>Morris, Robert (b. Feb. 9, 1931, Kansas City, Mo., U.S.) U.S. artist.  His first one-man exhibition of paintings was held in San Francisco in  1957. In 1960, while living in New York City, he began producing large,  monochromatic geometric sculptures, groups of which he exhibited in  specific spatial relationships. His work of this period greatly affected the  Minimalist movement, which sought to reduce art to its essence by elimi�  nating personal expression and historical allusion. From the late 1960s,  however, Morris moved toward a more spontaneous, if anonymous,  expressiveness. He experimented in a wide variety of forms, including  the �happening�; �dispersal pieces,� in which materials were strewn in  apparent randomness on the gallery floor; and environmental projects. His  work of the 1970s showed a preoccupation with paradoxes of mental and  physical imprisonment.</p><p>Morris, William (b. March 24, 1834, Walthamstow, near London,  Eng.�d. Oct. 3, 1896, Hammer�  smith) British painter, designer,  craftsman, poet, and social reformer,  founder of the Arts and Crafts Move�  ment. Born into a wealthy family, he  studied medieval architecture at  Oxford. He was apprenticed to an  architect, but visits to Europe turned  him toward painting. In 1861, with  Dante Gabriel Rossetti, Edward Burne-  Jones, Ford Madox Brown, and oth�  ers, he founded Morris, Marshall,</p><p>Faulkner &amp; Co., an association of  �fine art workmen� based on the  medieval guild. They produced fur�  niture, tapestry, stained glass, fab�  rics, carpets, and most notably  wallpaper designs. In 1891 Morris  founded the Kelmscott Press, and  over the next seven years it produced  53 titles in 66 volumes; its Works of Geoffrey Chaucer is one of the great�  est examples of the art of the printed book. Though he sought to produce  fine art objects for the masses, only the rich could afford his expensive  handmade products. A utopian socialist, he did much to develop British  socialism; in 1884 he formed the Socialist League. In 1877 he founded  the Society for the Protection of Ancient Buildings, one of the world�s  first preservationist groups. He wrote several volumes of poetry and many  prose romances, as well as the four-volume epic Sigurd the Volsung  (1876). His works and writings revolutionized Victorian taste, and he  ranks as one of the largest cultural figures of 19th-century Britain.</p><p>Morris dance Ritual folk dance mainly danced in rural England from  about the 15th century. The name, a variant of �Moorish,� possibly arose  in reference to the dancers� blacking their faces as part of the ritual dis�  guise. It is principally a fertility dance, performed especially in the spring.  Danced by groups of men often dressed in white and wearing bells on  their legs, the steps are varied and intricate and are maintained in a jog�  trot while handkerchiefs are waved in both hands. It calls for individual  characters such as a hobbyhorse and a fool.</p><p>Morris Jesup, Cape Cape, in the Peary Land region, northern Green�  land, on the Arctic Ocean. Situated 440 mi (710 km) from the North Pole,  it is one of the world�s most northerly points of land. Robert E. Peary was  the first explorer to reach it in 1900; it was named for Morris K. Jesup,  a merchant-banker who financed polar expeditions.</p><p>Morrison, Jim orig. James Douglas Morrison (b. Dec. 8, 1943,  Melbourne, Fla., U.S.�d. July 3, 1971, Paris, France) U.S. rock singer  and songwriter. He studied film at the University of California in Los  Angeles, where he met Ray Manzarek (b. 1935); with Robbie Krieger (b.  1946) and John Densmore (b. 1945), they formed the psychedelic rock  group the Doors, taking their name from Aldous Huxley�s book on mes�  caline, The Doors of Perception. The dark-edged eroticism of Morrison�s  baritone voice and pseudo-poetic lyrics helped make the band one of</p><p>rock�s most potent, controversial, and theatrical acts. Their popular hits  of the 1960s included �Light My Fire� and �Hello I Love You.� Morri�  son was known for his drinking and drug use and outrageous stage behav�  iour. In 1971 he left the Doors to write poetry and moved to Paris, where  he died of heart failure.</p><p>Morrison, Toni orig. Chloe Anthony Wofford (b. Feb. 18, 1931,  Lorain, Ohio, U.S.) U.S. writer. She studied at Howard and Cornell uni�  versities, taught at various universities, and worked as an editor before  publishing The Bluest Eye (1970), a novel dealing with some of the shock�  ing realities of the lives of poor blacks, and Sula (1973). The brilliant  Song of Solomon (1977) brought her national attention. Her later novels  include Tar Baby (1981), Beloved (1987, Pulitzer Prize), Jazz (1992), and  Paradise (1998). The African American experience, particularly that of  women, is the principal theme of her fiction. Her use of fantasy, her sinu�  ous poetic style, and her interweaving of mythic elements give her sto�  ries texture and great power. She was awarded the Nobel Prize for  Literature in 1993.</p><p>Morristown National Historical Park Historical park, Morris�  town, N.J., U.S. In the American Revolution the Continental army under  George Washington had its main winter campsite there in 1776-77 and  1779-80.

Morgan &amp; Co. (1914�  27) and organized the Kennecott Copper Corp. During World War I he  was an adviser to the Allied Maritime Transport Council, and after the  war he helped devise a national aviation policy. He served as ambassa�  dor to Mexico (1927-30). He briefly served in the U.S. Senate (1931)  before his death. His daughter Anne married Charles A. Lindbergh.</p><p>Morse, Carlton E. (b. June 4, 1901, Jennings, La., U.S.�d. May 24,  1993, Sacramento, Calif.) U.S. radio writer and producer. He worked as  a newspaper reporter before joining NBC radio as a writer in 1930. Morse  wrote, directed, and produced many radio programs, including the highly  popular soap opera One Man�s Family (1932-59; television, 1949-52),  the drama I Love a Mystery (1939�44, 1949-52), and the soap opera The  Woman in My House (1951�59).</p><p>Morse, Samuel F(inley) B(reese) (b. April 27, 1791, Charlestown,  Mass., U.S.�d. April 2, 1872, New York, N.Y.) U.S. painter and inven�  tor. The son of a distinguished geographer, he attended Yale University  and studied painting in England (1811-15). He returned home to work as  an itinerant painter; his portraits still rank among the finest produced in  the U.S. He cofounded the National Academy of Design and served as its  first president (1826�45). Independent of similar efforts in Europe, he  developed an electric telegraph (1832-35), believing his to be the first. He  developed the system of dots and dashes that became known internation�  ally as Morse code (1838). Though denied support from Congress for a  transatlantic telegraph line, he received congressional support for the first  U.S. telegraph line, from Baltimore to Washington; on its completion in  1844 he sent the message �What hath God wrought!� His patents brought  him fame and wealth.</p><p>Morse code System for representing letters, numerals, and punctuation  marks by a sequence of dots, dashes, and spaces. It is transmitted as elec�  trical pulses of varied lengths or analogous mechanical or visual signals,  such as flashing lights. The original system was invented by Samuel F.B.  Morse in 1838 for his telegraph; the International Morse Code, a simpler  and more precise variant with codes for letters with diacritic marks, was  devised in 1851. With minor changes, this code has remained in use for  certain types of radiotelegraphy, including amateur radio.</p><p>mortar Short-range artillery piece with a short barrel and low muzzle  velocity that fires an explosive projectile in a high-arched trajectory. Large  mortars were used against fortifications and in siege operations from  medieval times through World War I. Since 1915, small portable models  have been standard infantry weapons, especially for mountain or trench  warfare. Medium mortars, with a caliber of about 3^4 in. (70-90 mm), a  range of up to about 2.5 mi (4 km), and a bomb weight of up to 11 lbs (5  kg), are now widely used.</p><p>William Morris, drawing by C.M.

The ancient Romans are credited with  its invention. Mortar consists of sand mixed with cement and water. The  resulting substance must be sufficiently flexible to flow slightly but not  collapse under the weight of the masonry units. Before the 19th-century  invention of Portland cement, masons used thin joints of lime mortar,  which required greater precision than the thicker joints of portland-cement  mortar and were not as strong. For tilework, a very thin mortar called  grout is used. Pointing is the process of finishing a masonry joint.</p><p>mortgage In Anglo-American law, the method by which a debtor  (mortgagor) conveys an interest in property to a creditor (mortgagee) as  security for the payment of a money debt. The modern mortgage has its  roots in medieval Europe. Originally, the mortgagor gave the mortgagee  ownership of the land on the condition that the mortgagee would return  it once the mortgagor�s debt was paid off. Over time, it became the prac�  tice to let the mortgagor remain in possession of the land; it then became  the mortgagor�s right to remain in possession of the land so long as there  was no default on the debt.</p><p>Morton, James Douglas, 4th earl of (b. c. 1516�d. June 2,1581,  Edinburgh, Scot.) Scottish nobleman. Appointed chancellor by Mary,  Queen of Scots, in 1563, he conspired with other Protestant nobles to  murder Mary�s adviser David Riccio and probably was involved in the  murder of Lord Darnley. He led the nobles that drove Mary�s husband,  the earl of Bothwell, from Scotland and forced her to abdicate in favour  of her infant son, James (later James I of England). He became regent for  James in 1572 and restored the rule of law to Scotland. Resented by the  other nobles, he was forced to resign in 1578; he was later charged with  complicity in Darnley�s murder and executed.</p><p>Morton, Jelly Roll orig. Ferdinand Joseph La Menthe (b. Oct.  20, 1890, New Orleans, La., U.S.�d. July 10, 1941, Los Angeles, Calif.)  U.S. pianist and the first important composer in jazz. In his youth Mor�  ton was apparently active as a gambler, pool shark, and procurer. A pio�  neer ragtime piano player, he toured the country as a pianist from 1904,  making his first recordings in Chicago in 1923 with his ensemble the Red  Hot Peppers. An exponent of the New Orleans tradition, Morton achieved  success integrating elements of ragtime with improvised and arranged  ensemble passages, often on his own compositions such as �King Porter  Stomp.� By the early 1930s Morton�s fame had been overshadowed by  that of Louis Armstrong and other emerging innovators.</p><p>Mosaddeq Vmos-ad-.dekX, Mohammad (b. 1880, Tehran, Safavid  Persia�d. March 5, 1967, Tehran, Iran) Iranian politician and nationalist  leader. After law school in Switzerland, he served in the government until  Reza Khan became shah (1925). After Reza Shah was deposed in 1941,  Mosaddeq was reelected to the parliament (1944). Following Mosaddeq�s  successful nationalization of the British-owned Anglo-Iranian Oil Com�  pany, Mohammad Reza Shah Pahlavi (r. 1941-79) was virtually forced to  appoint him premier (1951). Tension between the monarch and the pre�  mier crested, however, and the shah attempted to dismiss him in 1953.  The resulting unrest forced the shah to flee the country until a coup,  backed by British and U.S. intelligence services, drove Mosaddeq from  power. Convicted of treason, he spent three years in prison and the rest  of his life under house arrest.</p><p>mosaic Surface decoration of small coloured components�such as  stone, glass, tile, or shell�closely set into an adhesive ground. Mosaic  pieces, or tesserae, are usually small squares, triangles, or other regular  shapes. Mosaics cannot create the variations of light and shadow that  paintings can, but glass tesserae can achieve a greater brilliance, espe�  cially those to which gold and silver foil have been applied. This tech�  nique was responsible for the great shimmering mosaics of the Byzantine  period. The earliest known mosaics date from the 8th century bc and were  made of pebbles, a technique refined by the Greeks in the 5th century.  The Romans used mosaics widely, particularly for floors. Pre-Columbian  Americans favoured mosaics of garnet, turquoise, and mother-of-pearl,  which usually encrusted shields, masks, and cult statues.</p><p>Mosby Vmoz-beV John Singleton (b. Dec. 6, 1833, Edgemont, Va.,  U.S.�d. May 30, 1916, Washington, D.C.) U.S. guerrilla leader. He  joined the Confederate cavalry in the American Civil War and was a scout  with Jeb Stuart�s troops. He led guerrilla units, called Mosby�s Rangers,  on raids on Union outposts in northern Virginia and Maryland, disrupt�  ing supply and communication lines. His capture of a Union general and  100 of his men behind federal lines (1863) earned him promotion to colo�</p><p>nel. After the war he resumed his law practice, and he later served as U.S.  consul to Hong Kong (1878-85) and as assistant attorney in the U.S. Jus�  tice Department (1904-10).</p><p>Mosca Vmo-skaV Gaetano (b.

Educated at the University of Palermo, he taught constitutional  law there (1885-88) and at the Universities of Rome (1888-96) and Turin  (1896-1908). A member of the Italian chamber of deputies from 1908, he  was made senator for life by Victor Emmanuel III in 1919. In works such  as The Ruling Class (1896) he argued that, historically and properly, soci�  ety has been governed by minorities, whether military, religious, oligar�  chic, or aristocratic.</p><p>Mosconi, Willie in full William Joseph Mosconi (b.

The son of a billiards parlor owner, Mosconi  began playing professionally in the early 1930s. Known for his accurate  rapid-fire shooting, he was world champion 15 times between 1941 and  1957 and once had a run of 526 consecutive balls.</p><p>Moscow Vmas-ko, 'mas-kau\ Russian Moskva \mas-'kva\ Capital and  largest city (pop., 2001 est.: 8,546,000) of Russia. It is located on both sides  of the Moskva River in western Russia, about 400 mi (640 km) southeast of  St. Petersburg and about 600 mi (970 km) east of Poland. Inhabited since  Neolithic times, the site was first mentioned as a village in 1147 and  became the capital of the principality of Moscow (Muscovy) in the late  13th century. It expanded in the 15th and 16th centuries under its grand  dukes Ivan III and Ivan IV and became the capital of a united Russia (1547-  1712). In 1812 it was occupied by the French under Napoleon and was  almost entirely destroyed by fire. In 1918 it became the capital of the Union  of Soviet Socialist Republics and expanded greatly. It suffered much damage  from German bombing in World War II. In 1993 it was the scene of armed  conflict between opposing government factions after the dissolution of par�  liament by Boris Yeltsin. The spiritual home of the Russian Orthodox church  for more than 600 years, it is a political, industrial, transportation, and cul�  tural centre. Its most notable structure is the Kremlin, a medieval fortress on  the Moskva with Red Square along its eastern wall. The Lenin Mausoleum  is nearby, and St. Basil�s Cathedral is at the southern end of the square.  Moscow is also home to the Bolshoi Theatre, Moscow State University, and  many other institutions of higher education.</p><p>Moscow Art Theatre Russian theatre specializing in theatrical natu�  ralism. It was founded in 1898 by Konstantin Stanislavsky (as artistic  director) and Vladimir Nemirovich-Danchenko (administrative director)  with the goal of replacing old-fashioned histrionic acting and heavy-  handed staging with a simpler and truer style. It opened with Aleksey Tol�  stoy�s Tsar Fyodor Ioannovich and won its first major success with Anton  Chekhov�s The Seagull. Along with other plays by Chekhov, the theatre  mounted new works by writers such as Maksim Gorky and Maurice Maeter�  linck. Its company received acclaim on European and U.S. tours in 1922  and influenced later theatrical development worldwide. Since 1939 it has  been known as the Moscow Academic Art Theatre.</p><p>Moscow River See Moskva River</p><p>Moscow school School of late  medieval Russian icon and mural  painting.

Rising in northeastern  France, it flows north, forming part of the border between Germany and  Luxembourg, then northeast into the Rhine River at Koblenz, Ger. In this  part of the valley are the vineyards that produce the famous Moselle  wines. The river, which is navigable for most of its course, passes Nancy,  Metz, and Thionville in France and Trier in Germany. Among its chief  tributaries are the Orne and the Saar.</p><p>Moser-Proll Vmo-zor-'proA, Annemarie orig. Annemarie Proll</p><p>(b. March 27, 1953, Kleinarl, Austria) Austrian downhill skier.

She holds the all-  time record of six women�s World Cup championships, including five in  succession (1971-75). She established a career record for both men and  women in individual World Cup races won (59).</p><p>Moses (fl. 14th�13th century bc) Prophet of Judaism. According to the  Book of Exodus, he was bom in Egypt to Hebrew parents, who set him  afloat on the Nile in a reed basket to save him from an edict calling for  the death of all newborn Hebrew males. Found by the pharaoh�s daugh�  ter, he was reared in the Egyptian court. After killing a brutal Egyptian  taskmaster, he fled to Midian, where Yahweh (God) revealed himself in a  burning bush and called Moses to deliver the Israelites from Egypt. With  the help of his brother Aaron, Moses pleaded with the pharaoh for the  Israelites� release. The pharaoh let them go after Yahweh had visited a  series of plagues on Egypt, but then sent his army after them. Yahweh  parted the waters of the Red Sea to allow the Israelites to pass, then  drowned the pursuing Egyptians. Yahweh made a covenant with the Isra�  elites at Mount Sinai and delivered the Ten Commandments to Moses, who  continued to lead his people through 40 years of wandering in the wil�  derness until they reached the edge of Canaan. He died before he could  enter the Promised Land. Authorship of the first five books of the Bible  (see Torah) is traditionally ascribed to him.</p><p>Moses, Edwin (b.

When arthritis impaired her embroidering, she turned to paint�  ing. She had her first exhibition in a drugstore in 1938 at age 78. She  went on to produce more than 1,000 nostalgic, naively executed scenes  of turn-of-the-century rural life (e.g., Catching the Thanksgiving Turkey,  Over the River to Grandma�s House). By 1939 her pictures were being  exhibited internationally, and from 1946 they were regularly reproduced  on holiday greeting cards.</p><p>Moses, Robert (b. Dec. 18,1888, New Haven, Conn., U.S.�d. July 29,  1981, West Islip, N.Y.) U.S. public official. He began his long career in pub�  lic service in New York City�s bureau of municipal research. In 1919 Gov.  Alfred E. Smith appointed him chief of staff of the New York state recon�  struction commission and, in 1924, head of both the New York and Long  Island state park commissions. For 40 years in these and related positions,  Moses supervised the vast expansion of the park system and the construc�  tion of numerous roads, bridges, tunnels, and housing projects in and  around the city, reshaping it on a grand scale in often controversial ways.</p><p>Moses de Leon orig. Moses ben Shem Tov (b. c. 1240, Leon�d.  1305, Arevalo) Reputed author of the Sefer ha-zohar, the most important  work of Jewish mysticism. Little is known of his life, though he is  believed to have lived in Guadalajara (the centre for Spanish adherents  of the Kabbala) until 1290 and later to have traveled widely. He repre�  sented the Zohar as an ancient book that he had discovered, but it is more  likely a work of his own authorship.</p><p>moshav \mo-'shav\ (Hebrew: �settlement�) Israeli cooperative com�  munity that combines privately farmed land and communal marketing,  sometimes with light industry as well. The land on a moshav belongs to  the state or the Jewish National Fund. The first successful moshavim were  organized in the 1920s. New immigrants were directed to these settle�  ments in the early years of the State of Israel.

In the 1830s and �40s he carefully  played off British and Boer interests against one another. Involved in a  series of wars, he proved a skillful tactician. In 1868 the British annexed  Sotho, and Moshoeshoe�s power waned. His descendant Moshoeshoe II  (1938-96) was the first king of independent Lesotho.</p><p>Moskva \mas-'kva\ River or Moscow River River, flowing through  Moscow province and part of Smolensk province, western Russia. The  river is 312 mi (502 km) long and drains an area of 6,800 sq mi (17,600  sq km). It runs through the city of Moscow to join the Oka River just below  Kolomna. The river flows southeast through the Volga basin. It is navi�  gable from Moscow and is an important source of the city�s water sup-  ply.</p><p>Mosley, Sir Oswald (Ernald), 6th Baronet (b. Nov. 16. 1896,  London, Eng.�d. Dec. 3, 1980, Orsay, near Paris, France) English poli�  tician and fascist. He served in the House of Commons (1918-31) as,  successively, a Conservative, an Independent, and a Labourite. After a  visit to Italy, he founded the British Union of Fascists in 1932. With his  followers, he distributed anti-Semitic propaganda, conducted hostile dem�  onstrations in the Jewish sections of eastern London, and wore Nazi-style  uniforms. During World War II he was interned (1940-43) with his wife,  Diana Guinness, a sister of Jessica and Nancy Mitford and friend of Adolf  Hitler. In 1948 Mosley founded the Union Movement, an amalgam of  right-wing book clubs.</p><p>mosque Islamic public place of prayer. The masjid jami\ or �congre�  gational mosque,� is the centre of community worship and the site of Fri�  day prayer services. Though the mosque�originally a sacred plot of  ground�has been influenced by local architectural styles, the building  has remained essentially an open space, usually roofed, with a minaret  sometimes attached. Statues and pictures are not permitted as decoration.  The minbar, a seat at the top of steps placed at the right of the mihrab, is  used by the preacher ( khatlb ) as a pulpit. Occasionally there is also a  maqsurah, a box or wooden screen originally used to shield a worship�  ing ruler from assassins. The minaret, originally any elevated place but  now usually a tower, is used by the muezzin (crier) to proclaim the call  to worship five times each day. During prayer, Muslims orient themselves  toward the qiblah wall, which is invariably oriented toward the Ka'bah in  Mecca. The mosque has traditionally been the centre of social, political,  and educational life in Islamic societies.</p><p>Mosque of Omar See Dome of the Rock</p><p>mosquito Any of 2,500 dipteran species in the family Culicidae.

It comprises a lowland about 40 mi (65 km)  wide that skirts the Caribbean Sea for about 225 mi (360 km). It was vis�  ited by Christopher Columbus in 1502, but Europeans had little contact with  the area until the rise of the buccaneers in the 17th century, after which  England established a protectorate there. It is named for the Miskito Indi�  ans. Spain, Nicaragua, and the U.S. disputed England�s protectorate until  the Clayton-Bulwer Treaty (1850). In 1894 the region was incorporated into  Nicaragua, but the northern part was granted to Honduras in 1960 by the  International Court of Justice. The chief town is Bluefields, at the mouth  of the Escondido River in Nicaragua.</p><p>moss Any of at least 12,000 species of small, spore-bearing land plants  in the bryophyte division, found worldwide except in salt water. Mosses  are simple and ancient plants that have survived nearly unchanged since  the Permian Period (290-248 million years ago). Commonly found in  moist, shady locations (e.g., forest floors), mosses may range in size from  microscopic to more than 40 in. (1 m) long. They prevent erosion and  release nutrients from the substrates on which they grow. The life cycle  shows clear alternation of generations between the sexual gametophyte,  with stemlike and leaflike structures that produce eggs and swimming  sperm, and the sporophyte, a raised stalk that ends in a spore case (spo�  rangium). Mosses also reproduce asexually by branching. The economi�  cally important genus Sphagnum forms peat. Many so-called mosses are  not bryophytes, including Irish moss (a red form of algae); beard moss,  Iceland moss, oak moss, and reindeer moss (all lichens); Spanish moss (a  name used variously for a lichen or an air plant of the pineapple family);  and club moss (an evergreen herb of the family Lycopodiaceae).</p><p>Moss, Stirling (b.

He won his first event in 1950 in England and went on to  win scores of races, including the British Grand Prix and the Monaco  Grand Prix (three times). In 1962 an accident ended his career. In all he  won 16 Grand Prix events and is considered the greatest driver never to  win a world championship.</p><p>Mossad \mo-'sad\ Hebrew Mossad Merkazi le-Modiin  U-letafkidim Meyuhadim ("Central Institute for Intelli�  gence and Security") Most important of Israel�s major intelligence  agencies. The Mossad carries out foreign espionage and covert political  and paramilitary operations. Its director reports directly to the prime min�  ister. It has enjoyed considerable success in operations against the coun�  try�s Arab neighbours and Palestinian organizations, and it has an  excellent reputation internationally for its effectiveness. Its secret agents  are credited with the apprehension of Adolf Eichmann in Argentina, the  execution of the killers of Israeli athletes at the 1972 Olympics, and the  rescue of Israeli hostages in the Entebbe incident. In the late 20th and early  21st centuries, the Mossad was criticized for its treatment of detainees,  many of whom were allegedly tortured and killed while in custody, and  for its efforts to assassinate some Palestinian political leaders.</p><p>Mossi \'mo-se\ People of Burkina Faso and other parts of western Africa,  mainly Mali and Togo. They speak Moore, a Gur language of the Niger-  Congo family. Mossi society, organized as in the former Mossi states (c.  1500-1895), is divided into royalty, nobles, commoners, and formerly  slaves. The morho naba (�big lord�) occupies a court in Ouagadougou.  In the colonial era the Mossi acted as trading intermediaries between the  forest states and the cities of the Niger. Today most of the nearly six mil�  lion Mossi are sedentary farmers.</p><p>Mossi states Complex of independent western African kingdoms (c.  1500-1895) around the headwaters of the Volta River, within present-day  Burkina Faso and Ghana. Though tradition held that their ancestors came  from the east, perhaps in the 13th century, the kingdoms� origins are  obscure. The Mossi people harassed the empires of Mali and Songhai and  vied for control of the Niger River. From c. 1400 the states acted as trading  intermediaries between the forest states and the cities of the Niger. They  remained independent until the French invasions of the late 19th century.</p><p>most-favoured-nation treatment Guarantee of same trading  opportunities (i.e., tariff concessions) already granted to the most favoured</p><p>nation (MFN). It is a method of establishing equal trading opportunities  among states by making originally bilateral agreements multilateral.  Attempts to guarantee equal trading opportunities were incorporated into  commercial treaties as far back as the early 17th century. The Anglo-  French treaty signed in 1860 became the model for many later trade  agreements, establishing a set of interlocking tariff concessions (see tar�  iff) later extended worldwide by most-favoured-nation treatment. MFN  treatment has always applied primarily to the duties charged on imports,  but specific provisions have extended the principle to other areas of eco�  nomic contact, including property rights, patents, and copyrights.

Sept. 8, 1977, Philadelphia, Pa.) U.S.  actor. He initially worked both on Broadway and in film, but after being  blacklisted in Hollywood after 1955, he worked principally in theatre in  New York City. He gave acclaimed performances in Ulysses in Nighttown  (1958) and Rhinoceros (1961), and he had lead roles in the musicals A  Funny Thing Happened on the Way to the Forum (1962) and Fiddler on  the Roof (1964). His later films included Mel Brooks�s The Producers  (1968) and The Front (1976), a film about the blacklisting era.

Located across the Tigris River  from the ruins of ancient Nineveh, which it succeeded, Mosul prospered  until 1258, when it was ravaged by the Mongols. It was a centre of the  Ottoman Empire (c. 1534-1918). After World War I (1914-18) it was occu�  pied by the British and in 1926 was ceded to Iraq. The country�s second  largest city and a chief commercial centre in the northwest, it has manu�  facturing (cement, textiles) and an oil refinery and nearby oil fields. It has  many ancient buildings, some dating from the 13th century, including the  Great Mosque and the Red Mosque.</p><p>Motagua \mo-'ta-gwa\ River River, eastern Guatemala. It is the coun�  try�s longest river, flowing about 250 mi (400 km) east and northeast into  the Gulf of Honduras near the Honduran border. Locally the river is called  the Silbapec near its source and the Rio Grande farther downstream. It is  a major transportation artery for bananas, coffee, and other crops raised  in its eastern valleys.</p><p>motel Hotel designed for persons traveling by automobile, with conve�  nient parking space provided (the name blends the words �motor hotel�).  Originally usually consisting of a series of separate or attached roadside  cabins, motels serve commercial and business travelers and persons  attending conventions and business meetings as well as vacationers and  tourists. By 1950 the automobile was the principal mode of travel in the  U.S., and motels were built near large highways, just as hotels had been  built near railroad stations.</p><p>motet Latin choral composition, generally in one movement. Its origins  are in the 13th century, when words (French mots) began to be added to  originally wordless polyphonic lines in settings of plainchant. It grew  directly out of the clausula, a polyphonic decoration of a portion of  organum, but it soon split off to become a separate composition, while  retaining a meaningless fragment of chant text and melody in the tenor  part. The upper texts often became a confusing mixture of sacred and  secular�and even anticlerical�poems, indicating its intended perfor�  mance in courtly as well as ecclesiastical settings. The motet was the most  important musical genre of the 13th century and an essential vehicle for  the development of polyphony. In the Renaissance, sacred motets, now  employing a single text, were written by composers such as Josquin des  Prez, Orlande de Lassus, and William Byrd, though it remains unclear how  often they were performed in church settings. In the 17th�18th centuries,  motets were written by Jean-Baptiste Lully, Marc-Antoine Charpentier, Hein�  rich Schutz, and Johann Sebastian Bach. After c. 1750 the genre declined,  and its distinguishing characteristics became diffuse.</p><p>moth Any of several thousand lepidopteran species, found in all but polar  habitats. Moths are chiefly nocturnal and have a stouter body, duller  colouring, and proportionately smaller wings than butterflies. They have  distinctive feathery antennae and, when at rest, fold their wings, wrap  them around the body, or hold them extended at their sides. Wingspans  range from less than 1 in.

Often  pictured as a beak-nosed, sharp-chinned old woman riding on the back of  a flying gander, she was first associated with nursery rhymes in Mother  Goose�s Melody (1781), published by the successors of John Newbery. The  name apparently derived from the title of Charles Perrault�s collection of  fairy tales Ma Mere I�oye (1697; �My Mother Goose�). The persistent  rumour that Mother Goose was an actual Boston woman is false.</p><p>Mother Jones See Mary Harris Jones</p><p>Mother Lode Country Former gold-rush belt, Sierra Nevada foothills,  central California, U.S. It was about 150 mi (240 km) long but only a few  miles wide. The gold rush was sparked by the 1848 discovery of placer  gold on John Sutter�s property. The term mother lode evolved from the  miners� concept of one main quartz vein with subsidiary offshoot veins.  Exhaustion of the main gold streaks and a government-enforced price  structure for gold caused mining operations to cease there in the 1930s.  The area is dotted with scores of ghost camps and old mining towns.</p><p>Mother's Day and Father's Day Holidays. In the U.S. a nation�  wide observance of Mother�s Day was suggested by Anna Jarvis of  Grafton, W.Va., and in 1908 formal observances were held in churches  in Grafton and Philadelphia. By 1911 every state celebrated the occasion  on the second Sunday in May. It was formalized by Congress in 1914. In  Britain, Mother�s Day is celebrated in mid-Lent as Mothering Sunday.  During the Middle Ages a custom developed of allowing those who had  moved away to visit their home parishes and their mothers on Laetare  Sunday, the fourth Sunday of Lent. Many other countries also celebrate  the holiday on this date, while some mark the observance at other times  of the year. Father�s Day was first celebrated in 1910 in Spokane, Wash.,  through efforts of Sonora Dodd and the YMCA. Celebrated on the third  Sunday in June, it became a legal holiday in 1972. Both days were origi�  nally largely religious holidays but have been commercialized with the  sending of greeting cards and the giving of gifts.</p><p>Motherwell, Robert (b. Jan. 24, 1915, Aberdeen, Wash., U.S.�d.  July 16, 1991, Provincetown, Mass.)</p><p>U.S. painter, writer, and teacher. He  received an art scholarship at 11, but  he earned degrees from Stanford and  Harvard before deciding to become  a serious painter. He espoused  Abstract Expressionism from the  beginning of his career, and his eru�  dite writings were largely respon�  sible for the intellectual tone of the  movement. In his Elegy to the Span�  ish Republic painting series, begun  in 1949 and continued over three  decades, he developed a limited rep�  ertory of simple, serene black forms  that were applied to the picture plane  in a way that created a sense of slow,  solemn movement. Though he  worked in various styles, his reputa�  tion rests on his pioneering work as  a founder and principal exponent of  Abstract Expressionism.</p><p>Motherwell, photograph by Arnold  Newman, 1959</p><p>�ARNOLD NEWMAN</p><p>motion Change in position of a body relative to another body or with  respect to a frame of reference or coordinate system. Motion occurs along  a definite path, the nature of which determines the character of the motion.  Translational motion occurs if all points in a body have similar paths rela�  tive to another body. Rotational motion occurs when any line on a body  changes its orientation relative to a line on another body. Motion relative  to a moving body, such as motion on a moving train, is called relative  motion. Indeed, all motions are relative, but motions relative to the Earth  or to any body fixed to the Earth are often assumed to be absolute, as the  effects of the Earth�s motion are usually negligible. See also Brownian  MOTION; PERIODIC MOTION; SIMPLE HARMONIC MOTION; SIMPLE MOTION; UNIFORM CIR�  CULAR MOTION.</p><p>motion, equation of Mathematical formula that describes the motion  of a body relative to a given frame of reference, in terms of the position,  velocity, or acceleration of the body. In classical mechanics, the basic equa�  tion of motion is Newton�s second law (see Newton's laws of motion),  which relates the force on a body to its mass and acceleration. When the  force is described in terms of the time interval over which it is applied,  the velocity and position of the body can be derived. Other equations of  motion include the position-time equation, the velocity-time equation, and  the acceleration-time equation of a moving body.</p><p>motion picture or movie Series of still photographs on film, pro�  jected in rapid succession onto a screen. Motion pictures are filmed with  a movie camera, which makes rapid exposures of people or objects in  motion, and shown with a movie projector, which reproduces sound syn�  chronized with the images. The principal inventors of motion-picture  machines were Thomas Alva Edison in the U.S. and the Lumiere brothers in  France. Film production was centred in France in the early 20th century,  but by 1920 the U.S. had become dominant. As directors and stars moved  to Hollywood, movie studios expanded, reaching their zenith in the 1930s  and �40s, when they also typically owned extensive theatre chains. Mov�  iemaking was marked by a new internationalism in the 1950s and �60s,  which also saw the rise of the independent filmmaker. The sophistication  of special effects increased greatly from the 1970s. The U.S. film indus�  try, with its immense technical resources, has continued to dominate the  world market to the present day. See also Columbia Pictures; MGM; Para�  mount Communications; RKO; United Artists; Warner Brothers.</p><p>motion sickness Sickness caused by contradiction between external  data from the eyes and internal cues from the balance centre in the inner  ear. For example, in seasickness the inner ear senses the ship�s motion,  but the eyes see the still cabin. This stimulates stress hormones and accel�  erates stomach muscle contraction, leading to dizziness, pallor, cold  sweat, and nausea and vomiting. Minimizing changes of speed and direc�  tion may help, as may reclining, not turning the head, closing the eyes,  or focusing on distant objects. Drugs can prevent or relieve motion sick�  ness but may have side effects. Pressing an acupuncture point on the wrist  helps some people.</p><p>motion study See time-and-motion study</p><p>motivation Factors within a human being or animal that arouse and  direct goal-oriented behaviour. Motivation has long been a central sub�  ject of study in psychology. Early researchers, influenced by Charles Dar�  win, ascribed much of animal and human behaviour to instinct. Sigmund  Freud believed that much of human behaviour was also based on irratio�  nal instinctive urges or unconscious motives. Walter B. Cannon proposed  that basic human drives served homeostatic functions by directing ener�  gies toward the reduction of physiological tensions. Behavioral psycholo�  gists, in contrast, stress the importance of external goals in prompting  action, while humanistic psychologists examine the role of felt needs.  Cognitive psychologists have found that a motive sensitizes a person to  information relating to that motive: a hungry subject, for example, will  perceive food stimuli as larger than other stimuli.

The  critical methods he used in his commentaries on Japanese classics pro�  vided the theoretical foundation of the modern Shinto revival. Rejecting  Buddhist and Confucian interpretations, he traced the genuine spirit of  Shinto to Japanese myths and sacred traditions. He reaffirmed the ancient  Japanese concept of musubi (the mysterious power of all creation and  growth), which has become one of the main tenets of modern Shinto.</p><p>motorcycle Bicycle or tricycle propelled by an internal combustion  engine. The first motor tricycle was built in 1884 in England, and the first  gasoline-engine motorcycle was built by Gottlieb Daimler in 1885. Motor�  cycles were widely used after 1910, especially by the armed forces in  World War I. After 1950 a larger, heavier motorcycle was used mainly for  touring and sport competitions. The moped, a light, low-speed motor  bicycle that can also be pedaled, was developed mainly in Europe, and  the sturdier Italian-made motor scooter also became popular for its  economy.</p><p>motorcycle racing Sport of running motorcycles on tracks, closed  circuits, or natural terrain. The main types are (1) road racing, conducted  on a course made up wholly or partly of public roads; (2) trials, conducted  both on and off the highway; (3) speedway racing, conducted on a short,  flat, oval dirt track; (4) drag racing, conducted on a straight quarter-mile  strip of pavement; (5) hill climbs, conducted on a large dirt mound; and  (6) motocross. The first international road race took place in Douran,  France, in 1905. The most famous race is the Tourist Trophy, established  on Britain�s Isle of Man in 1907. Motorcycle racing in North America  began in 1903; since 1937 the Daytona 200-mi (320-km) race has been  the leading U.S. race.</p><p>Motorola, Inc. U.S. manufacturer of wireless communications, elec�  tronic systems, and semiconductors. The company was founded in 1928  in Chicago by brothers Paul and Joseph Galvin as the Galvin Manufac�  turing Corp. In 1930 Galvin introduced a low-cost automobile radio under  the brand name Motorola, later adding Motorola police radios, home  radios, phonographs, two-way radios, and television sets. The company  changed its name to Motorola in 1947. Foreseeing a future demand for  transistors, Motorola became a leading manufacturer of them in 1958,  after licensing a transistor design from Bell Laboratories. Transistor  technology led to the development of microprocessors, which Motorola  marketed to computer makers in 1974. Although the company worked  with IBM Corp. and Apple Computer in 1993 to develop the first con�  sumer RISC (reduced-instruction-set computing) chip, Motorola realized  greater success as a producer of embedded microprocessors�ubiquitous  in kitchen appliances, pagers, video games, and handheld personal  computers. Motorola was also a leader in the development of cellular  telephone systems, and many of its cell phone designs became status  symbols.</p><p>Motown U.S. recording company that gave its name to the hugely  popular style of soul music that it created in the 1960s. It was founded in  Detroit, Mich., in 1959 by the songwriter Berry Gordy, Jr. (b. 1929).  (Motown, a contraction of �Motor Town,� refers to Detroit�s automotive  industry.) It scored its first nationwide hits with �Shop Around� (1960)  by the Miracles (see Smokey Robinson) and �Please Mr. Postman� (1961)  by the Marvelettes. Its roster soon included the Temptations, the Four  Tops, the Supremes, Marvin Gaye, and Stevie Wonder. The songwriting team  Holland-Dozier-Holland (see Brian and Eddie Holland) helped create the  �Motown sound,� which typically featured lyrical ballads sung to an  infectiously rhythmic accompaniment. Motown became one of the most  successful black-owned businesses and one of the most influential inde�  pendent record companies in U.S. history. Later Motown names included  the Isley Brothers, Gladys Knight and the Pips, and, in 1969, the Jackson  5 (see Michael Jackson). Motown continued to produce best-selling  recordings by new artists such as Lionel Richie into the 1980s. Gordy  moved the company headquarters to Los Angeles in 1971, and he finally  sold the label to MCA in 1988.</p><p>Mott, Lucretia orig. Lucretia Coffin (b. Jan. 3, 1793, Nantucket,  Mass., U.S.�d.

In 1811 she married a fellow  teacher, James Mott, and she became an official Quaker minister in 1821.  The Motts were active in the antislavery campaign, and Lucretia lectured  widely on social reform. In 1848 she and Elizabeth Cady Stanton orga�  nized the Seneca Falls Convention, and she thereafter devoted her atten�  tion primarily to women�s rights, writing articles and lecturing widely.  After the American Civil War, she also worked for voting rights for freed-  men. See also abolitionism; woman suffrage.</p><p>Moultrie Ymiil-tre, 'mol-treV William (b.

Mountains are considered  larger than hills, but the term has no standardized geologic meaning.  Mountains are formed by the folding, faulting, or upwarping of the Earth�s  surface due to the movement of plates (see plate tectonics) or by the  emplacement of volcanic rock onto the surface. For example, the Hima�  layan Mountains where India meets the Eurasian Plate were formed by a  collision between plates that caused extreme compressional folding and  the uplifting of large areas. The mountain ranges around the Pacific basin  are attributed to the sinking of one plate beneath another.

The pleasures of mountaineering lie not only in the con�  quest of the peak but also in the physical and spiritual satisfactions  brought about through intense personal effort, ever-increasing proficiency,  and contact with natural grandeur. The greater rewards do not come with�  out considerable risk and danger. The first great peak ascended in mod�  em times was Mont Blanc, in 1786. Other Alpine peaks followed, capped  by the ascent of the Matterhorn in 1865. By the 1910s, most peaks of the  Andes, the Rockies, and other Western Hemisphere ranges had been  climbed, including Mount McKinley (1913). Beginning in the 1930s a  series of successful ascents of mountains in the Himalayas occurred; the  summits of many of the Himalayan mountains were not reached until the  1950s, however. Of these climbs, the best known is the 1953 ascent of  Mount Everest by Edmund Hillary and Tenzing Norgay. In the 1960s moun�  taineering became an increasingly technical sport, emphasizing the use of  specialized anchoring, tethering, and grappling gear in the ascent of ver�  tical rock or ice faces.</p><p>Mountbatten (of Burma), Louis Mountbatten, 1 st Earl orig.

Mozambique is a republic with one legislature;  its head of state and government is the president. Inhabited in prehistoric  times, it was settled by Bantu peoples c. the 3rd century ad. Arab traders  occupied the coastal region from the 14th century, and the Portuguese  controlled the area from the early 16th century. The slave trade later  became an important part of the economy and, although outlawed in the  mid-18th century, continued illegally. In the late 19th century, private  trading companies began to administer parts of the inland areas. It became  an overseas province of Portugal in 1951. An independence movement  became active in the 1960s, and, after years of war, Mozambique was  granted independence in 1975. A single-party state under Frelimo (the  Mozambique Liberation Front), it was wracked by civil war in the 1970s  and �80s. In 1990 a new constitution ended its Marxist collectivism and  introduced privatization, a market economy, and multiparty government.  A peace treaty was signed with the rebels in 1992.</p><p>Mozambique Channel Strait, western Indian Ocean. Located  between Madagascar and Mozambique, it is about 950 mi (1,530 km)  long, 250-625 mi (400-1,000 km) wide, and has a maximum depth of  10,000 ft (3,000 m). An important shipping route for eastern Africa, it  receives all major Madagascar rivers and fronts the ports of Mahajanga  and Toliara in Madagascar. Along the Mozambican coast are the mouth  of the Zambezi River and the ports of Maputo and Beira.</p><p>Mozarabic \mo-'zar-3-bik\ art Architecture and religious arts of the  Mozarabs, Christians who lived in the Iberian Peninsula after the Arab  invasion of 711. Exposure of the conquered Christians to Islamic culture  and art forms proved influential, and their art became a synthesis of the  two traditions. The subject matter is Christian, but the style shows the  assimilation of Islamic decorative motifs and forms. Islamic influence is  seen especially in Mozarabic architecture, with its horseshoe-shaped  arches and ribbed domes. Through the emigration of Mozarabs, Islamic  influence in the arts spread northward into the rest of Europe.</p><p>Mozart Vmot-.sartV Wolfgang Amadeus orig. Johannes Chry-  sostomus Wolfgangus Theophilus Mozart (b. Jan. 27, 1756,  Salzburg, Archbishopric of Salzburg�d. Dec. 5, 1791, Vienna) Austrian  composer. Son of the violinist and composer Leopold Mozart (1719-87),  he was born the year of the publication of Leopold�s best-selling treatise  on violin playing. He and his older sister, Maria Anna (1751-1829), were  prodigies; at age five he began to compose and gave his first public per�  formance. From 1762 Leopold toured throughout Europe with his chil�  dren, showing off the �miracle that God allowed to be born in Salzburg.�  The first round of touring (1762-69) took them as far as France and  England, where Wolfgang met Johann Christian Bach and wrote his first  symphonies (1764). Tours of Italy followed (1769-74); there he first saw  the string quartets of Joseph Haydn and wrote his own first Italian opera.  In 1775-77 he composed his violin concertos and his first piano sonatas.  His mother died in 1779. He returned to Salzburg as cathedral organist  and in 1781 wrote his opera seria Idomeneo. Chafing under the archbish�  op�s rule, he was released from his position in 1781; he moved in with  his friends the Weber family and began his independent career in Vienna.  He married Constanze Weber, gave piano lessons, and wrote The Abduc�  tion from the Seraglio (1782) and many of his great piano concertos. The  later 1780s were the height of his success, with the string quartets dedi�  cated to Haydn (who called Mozart the greatest living composer), the  three great operas on Lorenzo Da Ponte�s librettos� The Marriage of  Figaro (1786), Don Giovanni (1787), and Cost fan tutte (1790)�and his  superb late symphonies. In his last year he composed the opera The Magic  Flute and his great Requiem (left unfinished). Despite his success, he  always lacked money (possibly because of gambling debts and a fond�  ness for fine clothes) and had to borrow heavily from friends. His death  at age 35 may have resulted from a kidney infection. No other composer  left such an extraordinary legacy in so short a lifetime.</p><p>Mozi or Mo-tzu Ymo-'dzM (b. 470?, China�d. 391? bc, China) Chi�  nese philosopher. Originally a follower of Confucius, Mozi evolved a  doctrine of universal love that gave rise to a religious movement called  Mohism. Like Confucius, he spent much of his life traveling from one  feudal state to another in search of a prince who would allow him to put  his teachings into practice. The Mozi, the principal Mohist work, con�  demned offensive war and urged people to lead a simple life harmful to  none. Mohism won a considerable body of followers, but it died out after  the 2nd century bc.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>MP3 &#x25BA; mudorsuan I 1305</p><p>MP3 abbreviation o/MPEG-l, audio layer 3 Standard technology  and format for the compression of audio signals into very small computer  files.

April/May 680, Damascus, Syria) First caliph (661-680) of the Umayyad  dynasty. Born into a clan that initially rejected Muhammad�s preaching, he  accepted Islam only after Muhammad had conquered Mecca. As gover�  nor of Damascus he built up the Syrian army until it was strong enough  to resist attacks of the Byzantine Empire. He opposed the leadership of c Au,  the fourth caliph, and eventually took the field against him. He claimed  the caliphate after 'All�s death. To win the loyalty of non-Syrian Arabs,  he introduced methods by which the tribes could keep the caliph informed  of their interests. He channeled tribal aggressiveness into anti-Byzantine  campaigns and in North Africa sent forces that captured Tripolitania and</p><p>Ifriqiyyah. To administer his large  empire, he adopted Roman and Byz�  antine procedures, employing Chris�  tian bureaucrats whose families had  served in Byzantine governments.  By securing his son as his successor,  he established hereditary rule.  Though disparaged by later Muslim  historians for deviating from  Muhammad�s leadership style and  by Shl'ites for his role in usurping  the authority of 'All and his family,  he is often portrayed in the Arabic  literary tradition as the ideal ruler.</p><p>Mubarak \mu-'ba-rak\, HosnT  (b.

The Mughal period marked a striking revival of Islamic architecture in  northern India, where Persian, Indian, and various provincial styles were  fused to produce works of great refinement. White marble and red sand�  stone were favoured materials. Most of the early Mughal buildings used  arches only sparingly, relying on post-and-beam construction. The use of  the double dome, a recessed archway inside a rectangular fronton (arena),  and parklike surroundings are typical of the Shah Jahan period (1628�  58), when Mughal design reached its zenith. Symmetry and balance  between the parts of a building were stressed, as was delicate ornamental  detail. Important Mughal undertakings include the Taj Mahal and the  palace-fortress at Delhi (begun 1638).</p><p>Mughal Vmu-goP dynasty or Mogul Vmo-goA dynasty Muslim  dynasty that ruled most of northern India from the early 16th to the mid-  18th century. The dynasty�s rulers, descended from Timur and Genghis  Khan, included unusually talented rulers over the course of seven genera�  tions, and the dynasty was further distinguished by its emperors� efforts to  integrate Hindus and Muslims into a united Indian state. Prominent among  the Mughal rulers were the founder, Babur (r. 1526-30); his grandson Akbar  (r. 1556-1605); and Shah Jahan. Under Aurangzeb (r. 1658-1707) the  empire reached its greatest extent, but his intolerance sowed the seeds for  its decline. It broke up under pressure from factional rivalries, dynastic  warfare, and the invasion of northern India in 1739 by Nadir Shah.</p><p>Mughal painting Style of painting, confined mainly to book illustra�  tions and miniatures, that evolved in India during the Mughal dynasty</p><p>(16th-19th centuries).

According to tradition, in 610 he was visited by the  angel Gabriel, who informed Muhammad that he was the messenger of  God. His revelations and teachings, recorded in the Qur�an, are the basis  of Islam. He began to preach publicly c. 613, urging the rich to give to  the poor and calling for the destruction of idols. He gained disciples but  also acquired enemies, whose plan to murder Muhammad forced him to  flee Mecca for Medina in 622. This flight, known as the Hijrah, marks the  beginning of the Islamic era. Muhammad�s followers defeated a Meccan  force in 624; they suffered reverses in 625 but repelled a Meccan siege  of Medina in 627. He won control of Mecca by 629 and of all Arabia by  630. He made his last journey to Mecca in 632, establishing the rites of  the HAJJ, or pilgrimage to Mecca. He died later that year and was buried  at Medina.

On his father�s death, he was appointed sultan of  French-ruled Morocco over his two brothers, largely because the French  expected him to be more compliant. His nationalist feelings were subtly  expressed throughout his rule. He protected Moroccan Jews from the  Vichy occupation in World War II (1939-45).

He reorganized Egyptian society in the aftermath of the Napoleonic occu�  pation, eliminating the remnants of the Mamluks (see MamlOk dynasty),  restricting native merchants and artisans, and stamping out peasant rebel�  lions. He nationalized most land, introduced the cultivation of cash crops,  and attempted to develop modern industry, but his efforts were under�  mined by a lack of trained workers, the deleterious effects of excessive  taxation, and a common disaffection with peasant conscription.

Its Arabic singular, mujahid, was  not an uncommon personal name from the early Islamic period onward.  However, the term did not gain popular currency as a collective or plural  noun referring to �holy warriors� until the 18th century in India, where it  became associated with Muslim revivalism. In the 20th century the term  was used most commonly in Iran and Afghanistan. In Iran the  Mojahedin-e Khalq (�Mujahideen of the People�), a group combining  Islamic and Marxist ideologies, engaged in a long-term guerrilla war  against the leadership of the Islamic republic. The name was most closely  associated, however, with members of a number of guerrilla groups oper�  ating in Afghanistan that opposed invading Soviet forces and eventually  toppled the Afghan communist government during the Afghan War  (1979-92). Rival factions thereafter fell out among themselves precipi�  tating the rise of one faction, the Taliban.

Silk�  worms (see silkworm moth) feed almost exclusively on the leaves of the  white mulberry (M. alba). Among the ornamentals in the family are the  paper mulberry and the Osage orange ( Maclura pomifera). Other species  include the India rubber tree, which is often placed in office lobbies, and  the wide-spreading banyan tree.</p><p>mule Offspring of a male ass and a  female horse. The less common cross  of a female ass and a male horse is  called a hinny. Most mules are ster�  ile. The mule resembles the horse in  height and in shape of neck and  croup (rump); it resembles the ass in  its long ears, small hooves, and short  mane. The coat is usually brown or  bay. Mules are 12-17.5 hands  (50-70 in., 120-180 cm) high and  weigh 600-1,500 lbs (275-700 kg).</p><p>They have been used as pack animals  for at least 3,000 years because of  their ability to withstand hardships.</p><p>mule deer Large-eared deer  (Odocoileus hemionus) of western</p><p>Mule deer buck (Odocoileus hemio�  nus).</p><p>HARRY ENGELS FROM THE NATIONAL AUDUBON SOCIETY  COLLECTION/PHOTO RESEARCHERS</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1308 I mullah &#x25BA; multiple sclerosis</p><p>L_</p><p>N</p><p>North America that lives alone or in small groups at high altitudes in  summer and lower altitudes in winter.

It means �lord�  and has also been used in North Africa as an honorific attached to the  name of a king, sultan, or member of the nobility. The title is now given  to a variety of religious leaders, including teachers in religious schools,  scholars of canon law, leaders of prayer in the mosques (imams), and recit�  ers of the Qur�an (qurra�). The word can also refer to the entire class that  upholds the traditional interpretation of Islam.</p><p>Muller Vmo-brX, Hermann Joseph (b. Dec. 21, 1890, New York,  N.Y., U.S.�d. April 5, 1967, Indianapolis, Ind.) U.S. geneticist. He  attended Columbia University. The possibility of consciously guiding  human evolution provided the initial motivation for his research, leading  him to work in the Soviet Union�s Institute of Genetics. He later assisted  the Republican forces in the Spanish Civil War before returning to the  U.S. in 1940; he thereafter taught principally at Indiana University (1945-  67). In 1926 he first induced genetic mutations through the use of X rays,  and he demonstrated that mutations are the result of breakages in chro�  mosomes and of changes in individual genes. His receipt of the Nobel  Prize in 1946 increased his opportunities to publicize the dangers posed  by accumulating spontaneous mutations in the human gene pool as a result  of industrial processes and radiation, and he devoted much energy to  increasing public awareness of the genetic dangers of radiation.</p><p>Muller VmiE-brV Johannes Peter (b. July 14, 1801, Koblenz,  France�d. April 28, 1858, Berlin, Ger.) German physiologist, compara�  tive anatomist, and natural philosopher. He studied at the Universities of  Bonn and Berlin and later taught at both. His discovery that each sense  organ responds to stimuli differently implied that external events are per�  ceived only by the changes they produce in sensory systems. His investi�  gations in physiology, evolution, and comparative anatomy contributed to  knowledge of reflexes, the secretion and coagulation processes, the com�  position of blood and lymph, vision, and hearing. His studies of tumour cell  structure began to establish pathological histology as a branch of science.</p><p>mullet Any of fewer than 100 species (family Mugilidae) of abundant,  commercially valuable schooling fishes found in brackish or fresh waters  throughout tropical and temperate regions. Mullets frequent shallow,  inshore areas, searching the sand or mud for microscopic plants and small  animals. They are silvery and 1-3 ft (30-90 cm) long, with large scales,  a short snout, a cigar-shaped body, a forked tail, and two distinct dorsal  fins, the first containing four stiff spines. The common, or striped, mullet  (Mugil cephalus ), cultivated in some areas, is a well-known species found  worldwide.</p><p>Mulligan, Gerry orig. Gerald Joseph Mulligan (b.

He worked as staff arranger for Gene Krupa�s band in 1946, later writing  arrangements and playing for the Miles Davis nonet�s Birth of the Cool  recordings (1949). Mulligan became one of the best-known exponents of  cool jazz (see bebop). In 1952 he formed a pianoless quartet featuring  trumpeter Chet Baker.</p><p>Mullis, Kary B(anks) (b. Dec. 28, 1944, Lenoir, N.C., U.S.) U.S. bio�  chemist. He received his doctorate from the University of California at  Berkeley. In 1983 he invented the polymerase chain reaction, with which  scientists can determine the order of nucleotides in a gene, use genetic  fingerprinting to identify individuals by their DNA patterns, study evo�  lution, and make medical diagnoses. He did his prize winning research at  Cetus Corp. and later became a freelance consultant. He shared a 1993  Nobel Prize with Michael Smith (b. 1932). He is known for his free�  wheeling personal style and his iconoclastic opinions and writings, includ�  ing Dancing Naked in the Mind Field (1998).</p><p>Mulroney \m3l-'ru-ne\, (Martin) Brian (b.

An ancient  city, it was taken by Alexander the Great in 326 bc. It fell to the Muslims  c. ad 712. For three centuries it remained the outpost of Islam in what was  then India. It was subject to the Delhi sultanate and the Mughal Empire  and was captured by the Afghans (1779) and the Sikhs (1818) before being  subjugated by the British (1849-1947). It is a commercial and industrial  centre, with textile mills, glass factories, and cottage industries, includ�  ing pottery and camelskin work. It is the site of many Muslim shrines and  an ancient Hindu temple.</p><p>multimedia Computer-delivered electronic system that allows the user  to control, combine, and manipulate different types of media, such as text,  sound, video, computer graphics, and animation. The most common mul�  timedia machine consists of a personal computer with a sound card, modem,  digital speaker unit, and CD-ROM. Interactive multimedia systems under  commercial development include cable television services with computer  interfaces that enable viewers to interact with TV programs; high-speed  interactive audiovisual communications systems, including video game  consoles, that rely on digital data from fibre-optic lines or digitized wire�  less transmission; and virtual reality systems that create small-scale arti�  ficial sensory environments.</p><p>multinational corporation Any corporation registered and operat�  ing in more than one country at a time, usually with its headquarters in a  single country. A firm�s advantages in establishing itself multinationally  include both vertical and horizontal economies of scale (reductions in cost  that result from an expanded level of output). Critics usually regard the  multinational corporation as destructive of local economies abroad and as  prone to monopolistic practices. See also conglomerate.</p><p>multiple birth Birth of more than one child from one pregnancy. Twins  are most common, born in 1 of about every 80 pregnancies. Identical twins  develop from a single fertilized egg, which splits into two genetically  identical embryos (though physical traits may be modified during their  development); they occur randomly but are more likely in older mothers.  Incomplete or late division results in conjoined twins. Fraternal twins  develop from two eggs fertilized by two sperm and are no more geneti�  cally alike than are other siblings. Most common among persons of Afri�  can ancestry and least common among those of Asian ancestry, fraternal  twins seem to run in families. Repeated twinning produces triplets, qua�  druplets, and so on; these multiples may be identical, fraternal, or a com�  bination. The use of fertility drugs has increased the number of high-order  multiple births. Medical and psychological �twin studies� compare fra�  ternal and identical twins to learn about genetic influences on various  characteristics and diseases.</p><p>multiple integral In calculus, the integral of a function of more than  one variable. As the integral of a function of one variable over an inter�  val results in an area, the double integral of a function of two variables  calculated over a region results in a volume. Functions of three variables  have triple integrals, and so on. Like the single integral, such construc�  tions are useful in calculating the net change in a function that results  from changes in its input values.</p><p>multiple personality disorder See dissociative identity disorder</p><p>multiple sclerosis \skl3-'ro-s9s\ Disease of the brain and spinal cord  in which gradual, patchy destruction of the myelin sheath of nerve fibres</p><p>Brian Mulroney, 1993.</p><p>RICK FRIEDMAN/BLACK STAR</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>multiplexing &#x25BA; Munch I 1309</p><p>causes interruption or disordered transmission of nerve impulses. Its early  symptoms may include limb weakness or trembling, visual problems,  sensory disturbances, unsteady walking, and defective bladder control,  which come and go irregularly. Attacks grow more severe, and some  symptoms become permanent, sometimes with eventual complete paraly�  sis. Average survival from onset is about 25 years, but a rare acute form  progresses over months. The cause remains uncertain and treatment unsat�  isfactory. Corticosteroids may ease symptoms. MS may be due to a  delayed immune response that attacks the myelin sheaths; suggested  causes include various common viruses. Dietary causes have also been  suggested.</p><p>multiplexing Process of transmitting multiple (but separate) signals  simultaneously over a single channel or line. Because the signals are sent  in one complex transmission, the receiving end has to separate the indi�  vidual signals. The two main types of multiplexing methods are time-  division multiplexing (TDM) and frequency-division multiplexing  (FDM). In TDM (typically used for digital signals) a device is given a  specific time slot during which it can use the channel. In FDM (typically  used for analog signals) the channel is subdivided into subchannels, each  with a different frequency width that is assigned to a specific signal.  Optical-fibre networks can use DWDM (dense wavelength-division mul�  tiplexing), in which different data signals are sent in different wavelengths  of light in the fibre-optic medium.</p><p>multiplier In economics, a numerical coefficient showing the effect of  a change in one economic variable on another. One macroeconomic mul�  tiplier, the autonomous expenditures multiplier, relates the impact of a  change in total national investment on the nation�s total income; it equals  the ratio of the change in total income to the change in investment. If, for  example, the total investment in an economy is increased by $1 million,  a chain reaction of increases in consumption is set off. Producers of raw  materials used in the investment projects and workers employed in the  projects gain $1 million in income. If they spend on average three-fifths  of that income, $600,000 will be added to the incomes of others. The  makers of the goods they buy will in turn spend three-fifths of their new  income on consumption. The process continues such that the amount by  which total income increases may be computed by an algebraic formula.  In this case, the multiplier equals 1/(1 - 3/5), or 2.5. This means that a  $1 million increase in investment creates a $2.5 million increase in total  income. Other multipliers include the money multiplier, which measures  money creation resulting from a change in monetary policy; the govern�  ment spending multiplier, which measures the change in national income  resulting from changes in fiscal policy; and the tax multiplier, which mea�  sures the changes in national income resulting from a change in taxes.  The concept of the multiplier process was popularized in the 1930s by  John Maynard Keynes as a means of measuring the effect of government  spending.</p><p>multiprocessing Mode of computer operation in which two or more  processors (see CPU) are connected and are active at the same time. In  such a system, each processor is executing a different program or set of  instructions, thus increasing computation speed over a system that has  only one processor (which means only one program can be executed at a  time). Because the processors must sometimes access the same resource  (as when two processors must write to the same disk), a system program  called the task manager has to coordinate the processors� activities.</p><p>multitasking Mode of computer operation in which the computer works  on multiple tasks at the same time. A task is a computer program (or part  of a program) that can be run as a separate entity. On a single-processor  system, the CPU can perform preemptive (also called time slicing or time  sharing) multitasking, where it executes part of one program, then  switches to another program, and then returns to the first one. On multi�  processing systems, each processor can handle a separate task.</p><p>Mumbai Vmom-.bl \ formerly Bombay City (pop., 2001 prelim.: city,  11,914,398; metro, area, 16,368,084), capital of Maharashtra state, west�  ern India. Located partly on Mumbai Island, it is flanked by Mumbai Har�  bour and the Arabian Sea. It is India�s principal port on that sea and one  of the largest and most densely populated cities in the world. The town  was acquired by the Portuguese in 1534. It was ceded to the English as  part of the dowry of Catherine of Braganza, who married Charles II in 1661.  Granted to the British East India Company in 1668, it became the compa�  ny�s headquarters in 1672, and in 1708 it was made the centre of British  authority in India. After the opening of the Suez Canal in 1869, Mumbai</p><p>grew to be the largest distributing entrepot in India. It remains India�s  economic hub and the heart of financial and commercial activity, its cul�  tural and education centre, and headquarters of its film industry.</p><p>Mumford, Lewis (b. Oct. 19, 1895, Flushing, N.Y., U.S.�d. Jan. 26,  1990, Amenia, N.Y.) U.S. architectural critic, urban planner, and cultural  historian. After studying at the City College of New York and at the New  School for Social Research, he taught at various universities and wrote  for The New Yorker, The Dial, and other magazines. In works such as  Technics and Civilization (1934), The City in History (1961), and The  Myth of the Machine (3 vol., 1967-70), Mumford analyzed the effects of  technology and urbanization on human societies, criticizing the dehuman�  izing tendencies of modern technological society and urging that it be  brought into harmony with humanistic goals and aspirations.

Mumming plays, which feature the death of a champion who is  restored to life by a doctor, are still performed in a few villages of England  and Northern Ireland. Originally mummers were bands of masked persons  who during winter festivals in Europe paraded through the streets and  entered houses to dance or play dice in silence. Thus the name has been  connected with words such as mumble and mute and non-English words  meaning �mask.� Mumming plays probably have links with primitive cer�  emonies marking important stages in the agricultural year.</p><p>mummy Body embalmed or preserved for burial in the manner of the  ancient Egyptians. The process varied from age to age in Egypt, but it  always involved removing the internal organs, treating the body with  resin, and wrapping it in linen bandages. (In later Egyptian times, the  organs were replaced after treatment.) Among the many other peoples who  practiced mummification were those of the Torres Strait, near Papua New  Guinea, and the Incas.</p><p>mumps or epidemic parotitis \,par-9-'tIt-9s\ Acute contagious viral  disease with inflammatory swelling of the salivary glands. Epidemics often  occur, mostly among 5- to 15-year-olds. Cold symptoms with low fever  are followed by swelling and stiffening in front of the ear, often on both  sides. This rapidly spreads toward the neck and under the jaw. Pain is  seldom severe, with little redness, but chewing and swallowing are dif�  ficult. During recovery in patients past puberty, other glands may be  affected, but usually not seriously. The testes may atrophy, but sterility is  very rare. While inflammation of the brain and meninges is fairly com�  mon, chances of recovery are good. Mumps needs no special treatment,  and patients usually develop immunity. Vaccination can prevent it.</p></section><section><p>Muna Vmii-noN Island Island, east-central Indonesia.

Located along the Isar River, it was founded c. 1158 at the site of an  ancient monastery. It became the capital of Bavaria under the ruling Wit-  telsbach family. The city developed as a centre of music and theatre  through the 19th century. After World War I it became a centre of right-  wing political ferment; it was the site of the 1923 Beer Hall Putsch, Adolf  Hitler�s attempted rising against the Bavarian government, and subsequent  Nazi Party activities. It was the site for the signing of the 1938 Munich  agreement. In World War II it suffered heavily from Allied bombing. Some  medieval structures survived, including the cathedral and town hall.

Though Czechoslovakia had defense  treaties with France and the Soviet Union, both countries agreed that areas  in the Sudetenland with majority German populations should be returned.  Hitler demanded that all Czechoslovaks in those areas depart; when  Czechoslovakia refused, Britain�s Neville Chamberlain negotiated an agree�  ment permitting Germany to occupy the areas but promising that all future  differences would be resolved through consultation.

His belief in the inner light of the Holy Spirit as opposed  to the authority of the Bible alienated the Lutherans. He preached widely,  championing the common people, and in 1525 he organized the working  classes of Miihlhausen. He led the Peasants' Revolt in Thuringia in 1524-  25; after the defeat of his forces, he was tortured, tried, and executed.</p><p>muqarnas See stalactite work</p><p>Muqi Fachang or Mu-hsi Fa-ch'ang (fl. 13th century, Sichuan  province, China) Chinese Chan (Japanese: Zen) Buddhist painter. Toward  the end of the Southern Song dynasty (1127-1279), Muqi fled to a mon�  astery near Hangzhou. He painted a variety of subjects�including land�  scapes, flowers, still lifes, and more orthodox iconographic subjects. The  most famous paintings associated with Muqi include Six Persimmons and  a triptych with a white-robed Guanyin flanked on either side by a scroll  of monkeys and a crane. The paintings vary in style and subject matter,  but there is throughout a sense of immediate vision and a totally respon�  sive hand, expressed with broad and evocative washes of ink. His paint�  ings on Chan themes stimulated many copies in Japan.</p><p>Murabitun, al- See Almoravid dynasty</p><p>Murad, Ferid (b. Sept. 14, 1936, Whiting, Ind., U.S.) U.S. pharma�  cologist. He received his M.D. and Ph.D. from Western Reserve Univer�  sity (later Case Western Reserve University). Murad showed that  nitroglycerin and related heart drugs induce the formation of nitric oxide,  a gas that increases the diameter of blood vessels. Along with Robert F.  Furchgott and Louis J. Ignarro, he was awarded a 1998 Nobel Prize for  the discovery that nitric oxide acts as a signaling molecule in the cardio�  vascular system. Their combined work uncovered an entirely new mecha�  nism for how blood vessels relax and widen. This discovery led to the  development of the drug Viagra, which is used to treat erectile dysfunc�  tion.</p><p>mural Painting applied to and made integral with the surface of a wall  or ceiling. Its roots can be found in the universal desire that led prehis�  toric peoples to create cave paintings�the desire to decorate their sur�  roundings and express their ideas and beliefs. The Romans produced large  numbers of murals in Pompeii and Ostia, but mural painting (not syn�  onymous with fresco) reached its highest degree of creative achievement  in Europe with the work of such Renaissance masters as Masaccio, Fra  Angelico, Leonardo da Vinci, Michelangelo, and Raphael. In the 20th cen�  tury, the mural was embraced by artists of the Cubist and Fauve move�  ments in Paris, revolutionary painters in Mexico (e.g., Diego Rivera, Jose  Clemente Orozco, David Alfaro Siqueiros), and Depression-era artists under  the sponsorship of the U.S. government (e.g., Ben Shahn, Thomas Hart  Benton).</p><p>Murasaki Shikibu \mu-Va-sa-ke-'she-ke-bu\ (b. c. 978, Kyoto, Japan)  Japanese writer. Her real name is unknown, and the primary source of  knowledge about her life is a diary she kept (1007-10). Her Tale ofGenji  (completed c. 1010) is a long and complex tale, concerned mostly with  the loves of Prince Genji and the women in his life. Supremely sensitive  to human emotions and the beauties of nature, it provides delightful  glimpses of life at the court of the empress Joto mon�in, whom Murasaki  served. It is generally considered the greatest work of Japanese literature  and perhaps the world�s first novel.</p><p>Murat \rmE-'ra\, Joachim (b. March 25, 1767, La Bastide-Fortuniere,  France�d.

He served in Italy and Egypt as a daring cavalry com�  mander, and later he aided Napoleon in his coup d�etat (1799) and mar�  ried Napoleon�s sister Caroline Bonaparte. He helped win the Battle of  Marengo (1800). Appointed governor of Paris, he was promoted to mar�  shal in 1804. After victories at the Battles of Austerlitz (1805) and Jena</p><p>(1806), he was made king of Naples  (1808), where he carried out admin�  istrative and economic reforms and  encouraged Italian nationalism. He  led troops in Napoleon�s Russian  campaign at the Battle of Borodino  (1812) but left the army during its  retreat from Moscow. He supported  Napoleon again during the Hundred  Days in 1815, but he was defeated  with his Neapolitan forces at the  Battle of Tolentino and was later  taken prisoner and shot.</p><p>Murchison River River, Western  Australia, Australia.

April 3, 1682, Sevilla) Spanish  painter. The most popular Baroque religious painter of 17th-century  Spain, he is noted for his idealized figures, most of them painted for reli�  gious orders and the confraternities of his native Sevilla (Seville). His  early works were executed in the naturalistic style of Francisco de Zur-  baran, but with the development of his mature style in the 1650s he soon  surpassed the older master in fame and popularity. The softly modeled  forms, rich colours, and broad brushwork of the later paintings, such as  the Immaculate Conception of 1652 (his favourite subject), reveal the  influence of 16th-century Venetian and Flemish Baroque painters.  Murillo�s works were copied and imitated throughout Spain and its  empire, and he was the first Spanish painter to achieve fame outside the  Spanish world.</p><p>Murji�ah \'mur-je-o\ One of the earliest sects of Islam to believe in the  postponement of judgment on those who have committed serious sins,  recognizing that God alone is able to decide whether a Muslim has lost  his faith. The Murji�ah flourished during the 7th-8th century, a period of  strife in the Muslim community. Unlike the Kharijites, a militant sect that  wanted to oust serious sinners from the community and declare jihad  against them, the Murji�ah, who advocated leaving great sinners to God,  claimed that no one who had professed Islam could be declared an infi�  del. When the Kharijites revolted against the Umayyad dynasty, the  Murji�ah declared that revolt against a Muslim ruler could not be justi�  fied under any circumstances. The Murji�ah were moderates who empha�  sized the love and goodness of God.</p><p>Murmansk Seaport (pop., 1999 est.: 382,700), northwestern Russia.

He directed his  first feature in 1919 and won international acclaim for Nosferatu (1922),  which is regarded by many as the most effective screen adaptation of Bram  Stoker�s Dracula, and The Last Laugh (1924). In 1927 he moved to Hol�  lywood, where he made films such as Sunrise (1927), his masterpiece,  and Tabu (1931; with Robert Flaherty).

It  can be classified as striated, cardiac, and smooth or as phasic and tonic  (responding quickly or gradually to stimulation, respectively). Striated  muscle, whose fibres appeal' striped under a microscope, is responsible</p><p>for voluntary movement. Most of these muscles are phasic. They are  attached to the skeleton and move the body by contracting in response to  signals from the central nervous system; contraction is achieved by the  sliding of thin filaments (of actin) between thick ones (of myosin); stretch  receptors in the tissue provide feedback, allowing smooth motion and fine  motor control. The branched fibres of cardiac muscle give it a netlike  structure; contraction originates in the heart�s muscle tissue itself with a  signal from the natural pacemaker; vagus and sympathetic nerves control  heart rate. Smooth muscle, the muscle of internal organs and blood ves�  sels, is generally involuntary and tonic; its cells can operate either col�  lectively or individually (in response to separate nerve endings) and have  different shapes. Disorders of voluntary muscle cause weakening, atro�  phy, pain, and twitching. Some systemic diseases (e.g., dermatomyositis,  polymyositis) can cause muscle inflammation.

Its low iron content makes it a good  electrical and thermal insulator.</p><p>muscular dystrophy \'dis-tra-fe\ Inherited disease that causes pro�  gressive weakness in the skeletal (and occasionally heart) muscle. Muscle  tissue degenerates and regenerates randomly and is replaced by scar tis�  sue and fat. There is no specific treatment. Physical therapy, braces, and  corrective surgery may help. Duchenne muscular dystrophy, the most  common, strikes only males. Symptoms, including frequent falls and dif�  ficulty in standing up, start in boys 3-7 years old; muscle wasting  progresses from the legs to the arms and then the diaphragm. Pulmonary  infection or respiratory failure usually causes death before age 20. The  gene can now be detected in female carriers and male fetuses. Becker  dystrophy, also sex-linked, is less severe and begins later. Patients remain  able to walk and usually survive into their 30s and 40s. Myotonic mus�  cular dystrophy affects adults of both sexes, with myotonia and degenera�  tion two to three years later, along with cataracts, baldness, and gonadal  atrophy. Limb-girdle dystrophy affects the pelvic or shoulder muscles in  both sexes. Facioscapulohumeral (face, shoulder-blade, and upper-arm)  dystrophy starts in childhood or adolescence and affects both sexes; after  initial symptoms of difficulty raising the arms, the legs and pelvic muscles  can be affected; the main facial effect is difficulty in closing the eyes.

Types of  museums include general (multidisciplinary) museums, natural-history  museums, science and technology museums, history museums, and art  museums. In Roman times the word referred to a place devoted to schol�  arly occupation (see Museum of Alexandria). The public museum as it is  known today did not develop until the 17th�18th century. The first orga�  nized body to receive a private collection, erect a building to house it, and  make it publicly available was the University of Oxford; the resulting  Ashmolean Museum opened in 1683. The 18th century saw the opening  of great museums such as the British Museum, Louvre, and Uffizi Gallery.  By the early 19th century the granting of public access to formerly pri�  vate collections had become common. What followed for the next 100  years was the worldwide founding of museums intended for the public.  In the 20th century, museums have broadened their roles as educational  facilities, sources of leisure activity, and information centres. Many sites  of historical or scientific significance have been developed as museums.  Museum attendance has increased greatly, often attracted by �block�  buster� exhibitions, though museums have had to become more finan�  cially resourceful due to constraints in public funding.</p><p>Museum of Modern Art (MOMA) Museum in New York City, the  world�s most comprehensive collection of U.S. and European art from</p><p>the late 19th century to the present. It was founded in 1929 by a group of  private collectors. The original building on 53rd St. opened in 1939; a  later addition and sculpture garden were designed by Philip Johnson  (1953). A condominium tower and western wing, doubling the exhibition  space, were completed in 1984. Its collections of Cubist, Surrealist, and  Abstract Expressionist paintings are extensive; other holdings include  sculpture, graphic arts, industrial design, architecture, photography, and  film. Through its permanent collections, exhibitions, and many publica�  tions, it exerts a strong influence on public taste and artistic production.</p><p>Museveni Xmu-'so-ven-.eX, Yoweri (Kaguta) (b. 1944, Mbarra dis�  trict, Uganda) President of Uganda (from 1986). As a university student  he led a group allied with African liberation movements. When Idi Amin  came to power in 1971, Museveni went into exile. He founded the Front  for National Salvation, which helped topple Amin in 1979. He replaced  Milton Obote as president in 1986, winning election to the post in 1996.  Though he rejected multiparty democracy, he allowed a free press and  private enterprise. He is credited with bringing stability and economic  growth to Uganda, though his support for rebels in other African coun�  tries has been controversial.</p><p>Musgrave, Thea (b. May 27, 1928, Barnton, Edinburgh, Scot.) Scot�  tish composer. She studied with Nadia Boulanger and Aaron Copland, and  she later taught at the University of California at Santa Barbara (1970-  78) and elsewhere in the U.S. She has written a number of dramatic con�  certos, some of which reflect her interest in music�s spatial dimension,  but she is best known for her operas, including The Voice of Ariadne  (1973), Mary, Queen of Scots (1977), and Simon Bolivar (1995).</p><p>Mushet Vmosh-otV, Robert Forester (b. 1811, Coleford, Gloucester�  shire, Eng.�d. January 1891, Coleford) British steelmaker. He was the  son of the ironmaster David Mushet (1772-1847). Robert�s discovery in  1868 that adding tungsten to steel greatly increases its hardness even after  air cooling produced the first commercial steel alloy, a material that  formed the basis for the development of tool steels for the machining of  metals. Mushet also discovered that the addition of manganese to steel  produced by the Bessemer process improved the steel�s ability to withstand  rolling and forging at high temperatures.</p><p>mushroom Fleshy spore-bearing structure of certain fungi (see fungus),  typically of the class Basidiomycetes. It arises from the mycelium, which  may live hundreds of years or a few months, depending on its food sup�  ply. Some species grow cellular strands (hyphae) in all directions, form�  ing a circular mat with a �fairy ring� of fruiting bodies around the outside.  Popularly, �mushroom� refers to the edible sporophores, while �toad�  stool� refers to inedible or poisonous sporophores, but there is no scien�  tific distinction between the two names. Mushrooms are classified by cap  shape. Umbrella-shaped sporophores with spore-shedding gills on the  undersurface are found chiefly in the agaric family (Agaricaceae). Mush�  rooms that bear spores in an easily detachable layer on the underside of  the cap belong to the family Boletaceae. Together the agarics and boletes  include most of the forms known as mushrooms. The highly prized edible  chanterelle is a bolete. The morels (class Ascomycetes) are popularly  included with the true mushrooms because of their shape and fleshy struc�  ture. Since some poisonous mushrooms closely resemble edible ones,  mushrooms intended for eating must be accurately identified. Mushroom  poisoning can cause nausea, diarrhea, vomiting, cramps, hallucinations,  coma, and sometimes death. See illustration opposite.</p><p>mushroom poisoning or toadstool poisoning Sometimes fatal  effect of eating any of the 70-80 species of poisonous mushrooms, or  toadstools. Many contain toxic alkaloids. The most deadly, Amanita phal-  loides (�death cup�), causes violent abdominal pain, vomiting, and bloody  diarrhea. Severe liver, kidney, and central-nervous-system damage lead to  coma. Over half the victims die. Treatment with thioctic acid, glucose,  and penicillin or by filtering the blood with charcoal may be effective. A.  muscaria causes vomiting, diarrhea, excessive perspiration, and confu�  sion, with recovery within 24 hours. Gyromitra esculenta toxin is usually  destroyed by cooking, but in susceptible people it affects the central ner�  vous system and breaks down blood cells, causing jaundice. Some poi�  sonous mushrooms resemble harmless ones, so extreme caution is needed  in wild-mushroom gathering.</p><p>Musial Vmyii-ze-olV Stanley Frank) (b.

The melody will usually be in a certain key or  mode, and in Western music it will often suggest harmony that may be  made explicit as accompanying chords or counterpoint. Music is an art  that, in one guise or another, permeates every human society. It is used  for such varied social purposes as ritual, worship, coordination of move�  ment, communication, and entertainment.</p><p>music box Mechanical musical instrument in which projecting pins on  a revolving brass cylinder or disk, encoding a piece of music, pluck tuned</p><p>Musial</p><p>PICTORIAL PARADE-EB INC.</p><p>king bolete or cep yellow morel</p><p>(Boletus edulis) (Morchella esculenta)</p><p>chanterelle</p><p>(Cantharellus cibarius)</p><p>cap (pileus)</p><p>.remains of universal veil</p><p>ring  (annulus)</p><p>basidiospores</p><p>meadow mushroom  (Agaricus campestris)</p><p>shaggy mane  (Coprinus comatus)</p><p>A mushroom typically consists of a stalk (stipe) and a cap (pileus). As the mushroom  develops from an underground mycelium and pushes upward, it is protected by a  thin membrane (universal veil), which eventually ruptures, leaving fragments on the  cap. Another membrane, attaching the cap to the stalk, also ruptures, allowing the  cap to expand and leaving a remnant ring (annulus) on the stalk. Radiating rows of  gills are found on the cap's undersurface; these bear the club-shaped reproductive  structures (basidia) which form minute spores known as basidiospores, of which a  single mushroom may produce millions.</p><p>� MERRIAM-WEBSTER INC.</p><p>steel tongues.

The  form derived from the taproom con�  certs given in city taverns in England  in the 18th�19th centuries. To meet  the demand for entertainment for the working class, tavern owners often  annexed nearby buildings as music halls, where drinking and smoking  were permitted. The originator of the English music hall as such was  Charles Morton, who built Morton�s Canterbury Hall (1852) and Oxford  Hall (1861) in London. Leading performers included Lillie Langtry, Harry  Lauder (1870-1950), and Gracie Fields. Music halls evolved into larger,  more respectable variety theatres, such as London�s Hippodrome and the  Coliseum. Variety acts combined music, comedy acts, and one-act plays  and featured celebrities such as Sarah Bernhardt and Herbert Tree. See also</p><p>VAUDEVILLE.</p><p>musica ficta Latin "feigned music" In medieval and Renaissance  music, the practice of inserting unnotated chromatic notes (see chromati�  cism) during performances. According to treatises of the times, it was left to  the performers to �correct� certain intervals. Which intervals were to be  changed, and how and under what circumstances, varied over time. This  practice was responsible for the introduction of accidentals (sharps, flats,  naturals) into musical notation. It also influenced the evolution of the major  and minor keys on which most Western music came to be based, for it modi�  fied the medieval church modes to resemble the major and minor scales.</p><p>musical or musical comedy Theatrical production that is charac�  teristically sentimental and amusing in nature, having a simple but dis�  tinctive plot and offering music, dancing, and dialogue. Its roots can be  traced to 18th- and 19th-century genres such as ballad opera, singspiel, and  opera comique. The Black Crook (1866), often called the first musical  comedy, attracted patrons of opera and serious drama as well as those of  burlesque shows. European composers such as Sigmund Romberg brought  to the U.S. a form of operetta that was the generic source for musical  comedy. George M. Cohan ushered in the genre�s heyday, and in the 1920s  and �30s it entered its richest period with the works of Jerome Kern, George  Gershwin and Ira Gershwin, Cole Porter, Richard Rodgers, and Oscar Ham-  merstein. Kern and Hammerstein�s Show Boat (1927) was perhaps the first  musical to employ music thoroughly integrated with the narrative. The  genre flourished in the 1950s with works by composers such as Leonard  Bernstein, but it began to decline in the late 1960s, by which time musi�  cals had begun to diverge in many different directions, incorporating ele�  ments such as rock music, operatic styling, extravagant lighting and  staging, social comment, nostalgia, and pure spectacle. Later notable  musical composers included Stephen Sondheim and Andrew Lloyd Webber.</p><p>musical notation Written, printed, or other visual representation of  music. There are two basic approaches to notating music. Tablature (such  as guitar chord diagrams) depicts the actions a performer is to take (in  particular, showing where to put the fingers to produce a given sound).  Symbolic notation describes the sounds themselves and includes methods  that vary from assigning pitches different letters of the alphabet to rep�  resenting a given combination of notes by a graphic sign. The Western  notation system combines rhythmic notation (the appearance of a note  indicates its duration) with pitch notation (the line or space on a staff  where a note is placed indicates its pitch). Thus, a single symbol shows  both pitch and duration, and a string of these symbols notates both melody  and rhythm. See illustration on following page.</p><p>musicology Scholarly and scientific study of music. In the late 18th  and early 19th centuries, such study was done by amateurs such as Lud�  wig von Kochel. As interest in earlier music grew, greater professionalism  was required, including the ability to decipher and assess musical manu�  scripts and historical documents. Musicology�s first great monument was  the first edition of Johann Sebastian Bach�s complete works (1851-99).  The scope of musicology may be summarized as covering the study of  the history and phenomena of music, including (1) form and notation, (2)</p><p>German music box, with disk in play�  ing position, from Leipzig, c. 1900</p><p>COURTESY OF THE MUSICAL WONDER HOUSE, WISCASSET,  MAINE; PHOTOGRAPH, JOHN SPINKS</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1316 I muskox &#x25BA; Muslim Brotherhood</p><p>L_</p><p>N</p><p>staff and bar lines</p><p>time signatures</p><p>staff</p><p>bar line</p><p>measure, or bar</p><p>3 /4 t</p><p>C 4 /4 I</p><p>0 2 / 2 *</p><p>clefs</p><p>accidentals</p><p>&amp;</p><p>treble, or G, clef</p><p>bass, or F, clef</p><p>alto, or C, clef</p><p>ft sharp  l7 flat  ^ natural  X double sharp  double flat</p><p>rests</p><p>O whole note</p><p>J.</p><p>J</p><p>J</p><p>J)</p><p>dotted half note</p><p>half note</p><p>quarter note  eighth note</p><p>sixteenth note</p><p>whole rest</p><p>half rest</p><p>^ quarter rest  7 eighth rest  *1 sixteenth rest</p><p>Common symbols used in modern musical notation.</p><p>� MERRIAM-WEBSTER INC.</p><p>biography, (3) the development of musical instruments, (4) music theory  (harmony, melody, modes, etc.), and (5) aesthetics, acoustics, and physi�  ology of the voice, ear, and hand.

The neck, legs, and tail are short.  Males stand 5 ft (1.5 m) tall and may weigh almost 900 lb (400 kg). Both  sexes have horns. The broad-based horns of males, up to 2 ft (60 cm)  long, start at the middle of the head, dip downward along the sides, and  then curve upward. The shaggy, dark brown coat reaches nearly to the  feet. Eskimos make a fine cashmerelike cloth from the thick wool under�  coat, which is shed in summer.

Designed as a larger version of the harquebus, muskets were fired  with matchlocks until flintlocks were developed in the 17th century; flint�  locks were replaced by percussion locks in the early 19th century. Early  muskets were often handled by two persons and fired from a portable rest.  Typically 5.5 ft (1.7 m) long and weighing about 20 lbs (9 kg), they fired  a ball about 175 yards (160 m) with little accuracy. Later types were  smaller, lighter, and accurate enough to hit a person at 80-100 yards  (75-90 m). The musket was replaced in the mid-19th century by the  breech-loading rifle.</p><p>Muskogean \m3s-'ko-je-9n\ languages Family of about eight North  American Indian languages spoken or formerly spoken across much of  what is now the southeastern U.S. In the 16th century Koasati (Coush-  atta) and Alabama were probably spoken in what is now northern Ala�  bama, Creek (Muskogee) and Hitchiti in Alabama and Georgia, and  Apalachee in the Florida Panhandle. To the west were Chickasaw in north�  ern Mississippi and western Tennessee and Choctaw in central Missis�  sippi. By the mid-19th century Apalachee was long extinct, and the forced  removals of the 1830s (see Trail of Tears) had pushed most of the remain�  ing Muskogean-speakers either west of the Mississippi or into Florida,  where the Seminole continue to speak a dialect of Creek in central Florida  and Mikasuki (Miccosukee) in the Everglades. The extant Muskogean  languages continue to be spoken, at least by adults, with Choctaw (in  Oklahoma and Mississippi) having the most speakers.</p><p>muskrat Either of two semiaquatic, brown rodent species (family Crice-  tidae) native to marshes, shallow  lakes, and streams of North America  and introduced into Europe. The  compact, heavy-bodied muskrat, or  musquash ( Ondatra zibethica ), is  about 12 in. (30 cm) long, not includ�  ing the long, scaly, flat tail. The par�  tially webbed hind feet have a stiff,  bristly fringe. Anal sacs produce a  musky secretion. The commercially  valuable fur consists of long, stiff,  glossy guard hairs overlying a dense,  soft underfur. Muskrats live in either  a burrow dug into the bank or a reed-and-rush mound built in the water.  They eat sedges, reeds, roots, and an occasional aquatic animal. The  round-tailed muskrat, or Florida water rat (Neofiber alleni ), is smaller.</p><p>Muslim Brotherhood Arabic Al-lkhwan al-Muslimun Religio-  political organization founded in Egypt in 1928 by Hasan al-Banna (1906-  49) that promoted the Qur�an and HadIth as the proper basis for society.

Marine  mussels are usually wedge-shaped or  pear-shaped and 2-6 in. (5-15 cm)  long. They may be smooth or ribbed  and often have a hairy covering. The  shells of many species are dark blue  or greenish brown on the outside and  pearly on the inside. Mussels attach  themselves to solid objects or to one  another, often forming dense clus�  ters.

A  member of a noble family, Musset came under the influence of Roman�  ticism in adolescence and produced his first work, Stories of Spain and  of Italy, in 1830. After an early play failed, he published historical trag�  edies and comedies but refused to let them be performed. He is best  remembered for his poetry, including light satirical pieces and poems of  dazzling technical virtuosity, as well as passionate, eloquent lyrics such  as �La Nuit d�octobre� (1837). A fitful love affair with George Sand  inspired some of his finest work.</p><p>Mussolini, Benito (Amilcare Andrea) known as II Duce</p><p>\il-'du-cha\ (b. July 29, 1883, Pre-  dappio, Italy�d. April 28, 1945,  near Dongo) Italian dictator (1922-  43). An unruly but intelligent youth,  he became an ardent socialist and  served as editor of the party newspa�  per, Avanti! (1912-14). When he  reversed his opposition to World War  I, he was ousted by the party. He  founded the pro-war II Popolo  d�Italia, served with the Italian army  (1915-17), then returned to his edi�  torship. Advocating government by  dictatorship, he formed a political  group in 1919 that marked the begin�  ning of fascism. A dynamic and cap�  tivating orator at rallies, he  organized the March on Rome (1922)  to prevent a socialist-led general strike. After the government fell, he was  appointed prime minister, the youngest in Italian history. He obtained a  law to establish the fascists as the majority party and became known as  II Duce (�The Leader�). He restored order to the country and introduced  social reforms and public works improvements that won widespread  popular support. His dreams of empire led to the invasion of Abyssinia  (later Ethiopia) in 1935. Supported in his fascist schemes by Adolf Hitler  but wary of German power, Mussolini agreed to the Rome-Berlin Axis  and declared war on the Allies in 1940. Italian military defeats in Greece  and North Africa led to growing disillusionment with Mussolini. After the  Allied invasion of Sicily (1943), the Fascist Grand Council dismissed him</p><p>from office. He was arrested and imprisoned but rescued by German com�  mandos, then became head of the Hitler-installed puppet government at  Salo in northern Italy.

Composing without training in his teens, he met several of the  composers with whom he later made up The Five, a group with the com�  mon goal of creating a nationalist school of Russian music. He received  his first composition lessons from Mily Balakirev in 1857; he soon resigned  from his military regiment to devote himself to music. He held a series  of government jobs, but his worsening alcoholism eventually made him  unemployable. His personal decline was accompanied by maturity as a  composer, and he wrote his major works, including the symphonic poem  Night on Bald Mountain (1867), the great opera Boris Godunov (1868),  and the famous piano cycle Pictures at an Exhibition (1874). His 65 songs  describe vivid scenes of Russian life and realistically reproduce the inflec�  tions of the spoken Russian language. After Mussorgsky�s death, his  works were published in drastically edited form, purged of their distinc�  tive starkness and unorthodox harmonies; the original versions were made  available in 1928.</p><p>Mustafa Kemal See Mustafa Kemal Ataturk</p><p>Mustang See P-51</p><p>mustard family Family Brassicaceae (or Cruciferae), composed of 350  genera of mostly herbaceous plants with peppery-flavored leaves.

Mut  may have originated either in the Nile River delta or in Middle Egypt.  During the 18th dynasty (1539-1292 bc), she became the companion of  the god Amon at Thebes. Amon, Mut, and the young god Khons (said to  be her son) formed the Theban triad. The name Mut means �mother,� and  her role was that of an older woman among the gods. She was usually  represented as a woman wearing a double crown; she was also sometimes  depicted with the head of a lioness.</p><p>mutagen Vmyii-to-jonV Any agent capable of altering a cell�s genetic  makeup by changing the structure of the hereditary material, DNA. Many  forms of electromagnetic radiation (e.g., cosmic rays, X rays, ultraviolet  light) are mutagenic, as are various chemical compounds. The effects of  some mutagens are increased or suppressed in some organisms by the  presence of certain other, nonmutagenic substances; oxygen, for example,  makes cells more sensitive to the mutagenic effects of X rays.</p><p>Mutanabb?

Al-MutanabbI received an education, unusual for his time and rank,  because of his poetic talent. He lived among the Bedouin and, claiming to  be a prophet, led an unsuccessful Muslim revolt in Syria. After two years�  imprisonment he recanted and became a wandering poet, eventually leav�  ing Syria for Egypt and Iran. He primarily wrote panegyrics in a flowery,  bombastic style marked by improbable metaphors. His poetic voice is  proud and arrogant in tone, and his verse is crafted with consummate skill  and artistry. His powerful influence on Arabic poetry persisted into mod�  ern times.</p><p>mutation Alteration in the genetic material of a cell that is transmitted  to the cell�s offspring. Mutations may be spontaneous or induced by out�  side factors (mutagens). They take place in the genes, occurring when one  base is substituted for another in the sequence of bases that determines  the genetic code, or when one or more bases are inserted or deleted from  a gene. Many mutations are harmless, often masked by the presence of a  dominant normal gene (see dominance). Some have serious consequences;  for example, a particular mutation inherited from both parents results in  sickle-cell anemia. Only mutations that occur in the sex cells (eggs or</p><p>Atlantic ribbed mussels (Modiolus  demissus)</p><p>WALTER DAWN</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1318 I Mu'tazilah &#x25BA; myasthenia gravis</p><p>L_</p><p>N</p><p>sperm) can be transmitted to the individual�s offspring. Alterations caused  by these mutations are usually harmful. In the rare instances in which a  mutation produces a beneficial change, the percentage of organisms with  this gene will tend to increase until the mutated gene becomes the norm  in the population. In this way, beneficial mutations serve as the raw mate�  rial of EVOLUTION.</p><p>Mu'tazilah \mu-'ta-zi-b\ In Islam, one of two early religious groups. The  term applies primarily to members of a theological school that flourished in  Al- Basrah and Baghdad in the 8th-10th century. These Mu'tazilah were the  first Muslims to employ systematically the categories and methods of Hel�  lenistic philosophy to derive their dogma. The tenets of their faith included  belief in the oneness of God ( tawhid ), advocation of human free will (the  ability to choose between good and evil), and the fundamental belief in  God�s fairness (i.e., God will punish only those deserving of punishment).  Their doctrine of a created Qur�an (the eternal nature of which was advo�  cated by their opponents) held sway in the caliphal court briefly in the early  9th century and was the first instance in the Muslim world in which politi�  cal authorities attempted to enforce any form of doctrinal rigour; the  Mu'tazilah theological program soon lost political sway, however, and had  faded by the 13th century. Though it was ultimately abandoned by Sunnite  Muslims (the group�s methods came to be accepted by some ShTite groups),  its true importance lay in the fact that it forced other theological groups to  embrace a more rigorous dialectical method (see kalam).</p><p>mutiny Any concerted resistance to lawful military authority. Mutiny  was formerly regarded as a most serious offense, especially aboard ships  at sea. Wide disciplinary powers were given the commanding officer,  including the power to inflict capital punishment without a court-martial.  With the development of radio communications, the threat diminished and  harsh punishment was prohibited in the absence of a court-martial.</p><p>Mutsuhito See Meiji emperor</p><p>mutual fund or unit trust or open-end trust Company that  invests the funds of its subscribers in diversified securities and issues units  representing shares in those holdings. It differs from an investment trust,  which issues shares in the company itself.

Edward James Mug-  geridge (b. April 9, 1830, Kingston upon Thames, Surrey, Eng.�d.  May 8, 1904, Kingston upon Thames) English photographer. He immi�  grated to the U.S. from England as a young man, and in 1868 his photos  of Yosemite Valley made him famous. Hired by Leland Stanford to pho�  tograph a trotting horse in motion, to test Stanford�s contention that it  lifted all four legs simultaneously, he developed a special fast shutter for  his battery of 12 to 24 cameras, and in 1877 he proved Stanford right. He  lectured widely on animal locomotion, illustrating his lectures with his  zoopraxiscope, a predecessor of the movie projector. His extensive pho�  tographic studies of human movement (1884-87) have been useful to art�  ists and scientists.</p><p>Mwene Mata pa Vmwa-na-ma-'ta-poX Title borne by a line of kings  ruling a South African territory between the Zambezi and Limpopo riv�  ers, in what is now Zimbabwe and Mozambique, from the 14th to the  17th century.

It is located on the boundary between southeastern Demo�  cratic Republic of the Congo (Zaire) and Zambia, west of the southern  tip of Lake Tanganyika. Part of the Congo River system, it is 76 mi (122  km) long and has a surface area of 1,900 sq mi (4,920 sq km). The Lua-  pula River, a headstream of the Congo River, flows through it. The Bang-  weulu Swamps adjoin the lake.</p><p>My Lai \'me-Tl\ Massacre (March 16, 1968) Mass killing of as many  as 500 unarmed villagers by U.S. soldiers in the hamlet of My Lai dur�  ing the Vietnam War. A company of U.S. soldiers on a search-and-destroy  mission against the hamlet found no armed Viet Cong there but nonethe�  less killed all the elderly men, women, and children they could find; few</p><p>villagers survived. The incident was initially covered up by high-ranking  army officers, but it was later made public by former soldiers. In the ensu�  ing courts-martial, platoon leader Lt. William Calley was accused of  directing the killings and was convicted of premeditated murder and sen�  tenced to life in prison; but Pres. Richard Nixon intervened on his behalf,  and he was paroled after three years. The massacre and other atrocities  revealed during the trial divided the U.S. public and contributed to grow�  ing disillusionment with the war.</p><p>Myanmar \'myan-,mar\ or Burma officially Union of Myanmar</p><p>Country, Southeast Asia, on the Bay of Bengal and the Andaman Sea. Area:  261,228 sq mi (676,577 sq km). Population (2005 est.): 46,997,000. Capi�  tals: Yangon (Rangoon)/Pyinmana. Inhabitants are chiefly Burman; oth�  ers include Chin, Shan, and Karen. Languages: Burmese (official), many</p><p>indigenous languages. Religions: Bud�  dhism, traditional beliefs, Christianity,  Islam, Hinduism. Currency: kyat. Myan�  mar may be divided into five main regions:  the northern mountains, the western  ranges, the coastal plains, the central lowlands, and the Shan Plateau in  the east. Major rivers are the Irrawaddy and the Salween. The tropical cli�  mate is greatly influenced by the monsoons of southern Asia. Only about  one-sixth of this largely mountainous land is arable. It has a centrally  planned, developing economy that is largely nationalized and based on  agriculture and trade. Rice is the most important crop and principal export;  teak is also important. Myanmar is ruled by a military regime; its head  of state and government is the chairman of the State Peace and Devel�  opment Council, assisted by the prime minister. The area was long inhab�  ited, with the Mon and Pyu states dominant from the 1 st century bc to the  9th century ad. It was united in the 11th century under a Burmese dynasty  that was overthrown by the Mongols in the 13th century. The Portuguese,  Dutch, and English traded there in the 16th�17th century. The modem  Myanmar (Burmese) state was founded in the 18th century by Alaung-  paya. Conflict with the British over Assam resulted in a series of wars, and  Myanmar fell to the British in 1885. Under British control, it became  Burma, a province of India. It was occupied by Japan in World War II and  became independent in 1948. The military took power in a coup in 1962  and nationalized major economic sectors. Civilian unrest in the 1980s led  to antigovernment rioting that was suppressed by force. In 1990 opposi�  tion parties won in national elections, but the army continued in control.  Trying to negotiate for a freer government amid the unrest, Aung San Suu  Kyi was awarded the Nobel Peace Prize in 1991.</p><p>Bay of  Bengal</p><p>Cape</p><p>Negrais</p><p>myasthenia gravis V.ml-os-'the-ne-o-'gra-vosV Chronic autoimmune  disease causing muscle weakness.

The pattern varies, but usually muscles used in  eye movements, facial expressions, chewing, swallowing, and respiration  are affected first, then neck, trunk, and limb muscles. Severe cases impede  breathing. Anticholinesterase drugs stimulate nerve-impulse transmission,  and corticosteroids may help. Removal of the thymus has improved severe  cases. Remission lasting several years may occur.</p><p>mycelium \ml-'se-le-3m\ Mass of branched, tubular filaments (hyphae)  of fungi (see fungus) that penetrate soil, wood, and other organic matter.  The mycelium makes up the thallus (undifferentiated body) of a typical  fungus. The mass may be microscopic in size or developed into visible  structures, such as brackets, mushrooms, puffballs, or truffles. The myce�  lium produces spores, directly or through special fruiting bodies.</p><p>Mycenae \ml-'se-ne\ Prehistoric city, northeastern Peloponnese, Greece.  A natural rock citadel, it was the legendary capital of Agamemnon. It  flourished during the Bronze Age, building the distinctive Mycenaean civi�  lization. It was at its height in the Aegean c. 1400 bc and declined c. 1100  bc with the invasion of the Dorians from the north. Excavations at Myce�  nae began in 1840, but the most celebrated discoveries there were those  by Heinrich Schliemann c. 1876. Ruins include the Lion Gate, acropolis,  granary, and several royal beehive tombs and shaft graves.</p><p>Mycenaean \ l ml-s9- , ne-9n\ Any member of a group of warlike Indo-  European peoples who entered Greece from the north starting c. 1900 bc  and established a Bronze Age culture on the mainland and nearby islands.  Their culture was dependent on that of the Minoans of Crete, who for a  time politically dominated them. They threw off Minoan control c. 1400  and were dominant in the Aegean until they themselves were over�  whelmed by the next wave of invaders c. 1150. Mycenae continued to exist  as a city-state into the period of Greek dominance, but by the 2nd cen�  tury ad it was in ruins. Mycenaean myths and legends lived on through  oral transmission into later stages of Greek civilization and form the basis  of Homeric epic and Greek tragedy. Their language is believed to be the  most ancient form of Greek.</p><p>mycobacterium \ l mI-ko-bak-'tir-e-3m\ Any of the rod-shaped bacte�  ria that make up the genus Mycobacterium. The two most important spe�  cies cause tuberculosis and leprosy in humans; another species causes  tuberculosis in both cattle and humans. Some mycobacteria live on decay�  ing organic matter; others are parasites. Most are found in soil and water  in a free-living form or in diseased tissue of animals. Various antibiotics  have had some success against mycobacterium infections.</p><p>mycology \ml-'ka-l3-je\ Study of fungi (see fungus), including mush�  rooms and yeasts. Many fungi are useful in medicine and industry. Myco-  logical research has led to the development of such antibiotic drugs as  penicillin, streptomycin, and tetracycline. Mycology also has important appli�  cations in the dairy, wine, and baking industries and in the production of  dyes and inks. Medical mycology is the study of fungus organisms that  cause disease in humans.</p><p>mycoplasma V.ml-ko-'plaz-moX Any of the bacteria that make up the  genus Mycoplasma. They are among the smallest of bacterial organisms.  The cell varies from a spherical or pear shape to that of a slender branched  filament. Mycoplasma species are gram-negative (see gram stain) and do  not require oxygen. They are colonial microorganisms that lack cell walls.  They are parasites of joints and the mucous membranes lining the respi�  ratory, genital, or digestive tracts of cud-chewing animals, carnivores,  rodents, and humans. Toxic by-products excreted by the bacteria accu�  mulate in the host�s tissues, causing damage. One species causes a wide�  spread but rarely fatal pneumonia in humans.</p><p>mycorrhiza V.mi-ko-'ri-zoN Product of close association between the  branched, tubular filaments (hyphae) of a fungus and the roots of higher  plants. The association usually enhances the nutrition of both the host  plant and the fungal symbiont. The establishment and growth of certain  plants (e.g., citrus plants, orchids, pines) depends on mycorrhizae; other  plants survive but do not flourish without their fungal symbionts.</p><p>mycoses See fungal diseases</p><p>mycotoxin Toxin produced by a fungus. Numerous and varied, myc-  otoxins can cause hallucinations, skin inflammation, liver damage, hem�  orrhages, miscarriage, convulsions, neurological disturbances, and/or  death in livestock and humans. The best-known mycotoxins are aflatoxin,  ergot toxin, and the agents of mushroom poisoning.</p><p>Myerson, Goldie See Golda Meir</p><p>mynah or myna \'mI-no\ Any of several Asian songbird species of the  starling family (Stumidae). The hill mynah ( Gracula religiosa) of southern  Asia, called the grackle in India, is about 10 in. (25 cm) long and glossy  black with white wing patches, yellow wattles, and orange bill and legs. In  the wild, it chuckles and shrieks; caged, it learns to imitate human speech  far better than its chief rival, the gray parrot. The common, or Indian,  mynah ( Acridotheres tristis ) was introduced into Australia, New Zealand,  and Hawaii. The crested mynah (A. cristatellus ), native to China and Indo�  nesia, was introduced into British Columbia, Canada, but has not spread.</p><p>myositis V.ml-o-'sI-tosV Inflammation of muscle tissue, often from bacte�  rial, viral, or parasitic infection but sometimes of unknown origin. Most  types destroy muscle and surrounding tissue. Bacteria may directly infect  muscle (usually after injury) or produce substances toxic to it. Some  chronic diseases (e.g., tuberculosis, third-stage syphilis) can involve the  muscles. Parasites (e.g., tapeworms, protozoans) in contaminated food  enter the bloodstream from the intestines and lodge in muscle.</p><p>myotonia V.ml-o-'to-ne-oN Disorder causing difficulty relaxing con�  tracted voluntary muscles. All or only a few may be affected. Myotonia  seems to originate in the muscles (myopathy) rather than the nervous sys�  tem. Certain toxins can cause it. A hereditary form, myotonia congenita  (Thomsen disease), can affect eyelid and eye motion, swallowing, or talk�  ing. Quick movements cause muscle stiffening. There is also a myotonic  form of muscular dystrophy. Analgesics, anesthetics, and anticonvulsant  drugs can alleviate the symptoms.</p><p>Myra Vml-roX Ancient city, Lycia, southern coast of Anatolia. Its loca�  tion was near the modern city of Kale in southwestern Turkey. Ancient  ruins dating from the 5th to 3rd centuries bc include an acropolis, a mag�  nificent theatre, and several rock-cut tombs that resemble wooden houses  and shrines. St. Paul is known to have visited Myra in the 1st century ad,  and St. Nicholas was bishop of the city in the 4th century. It was the capi�  tal of Byzantine Lycia until it fell to the �Abbasids in 808.</p><p>Myrdal \'mi�r- l dal,\ English Vmir-.dalV (Karl) Gunnar (b. Dec. 6,  1898, Gustafs, Dalarna, Swed.�d. May 17, 1987, Stockholm) Swedish  economist and sociologist. He received his Ph.D. from Stockholm Univer�  sity and taught there from 1933 until 1967. His early work emphasized pure  theory, but he later focused on applied economics and social problems. He  explored the social and economic problems of African Americans in the  U.S. (1938-40) and in 1944 published the classic study An American  Dilemma, in which he presented his theory that poverty breeds poverty. In  regard to development economics, he argued that rich and poor countries,  rather than converging economically, might well diverge, the poor coun�  tries becoming poorer as the rich countries enjoyed economies of scale and  the poor ones were forced to rely on primary products. In 1974 he shared  the Nobel Prize with Friedrich von Hayek. His wife, Alva Myrdal (1902-  86), was a sociologist, diplomat, UN administrator, and antiwar activist;  she shared the 1982 Nobel Peace Prize with Alfonso Garcia Robles.</p><p>Myron Vml-rsnV (b. c. 480 bc, Greece�d. 440 bc) Greek sculptor.

Situated midway between the Kaveri and Kab-  bani rivers, the site was inhabited before the 3rd century bc. The city was  the capital of the princely state of Mysore (1799-1831), then it was occu�  pied by the British. The state�s second largest city, it is an important  industrial centre producing textiles, chemicals, and foodstuffs. Sites of  interest include the 17th-century British residency, the maharaja�s palace,  and the University of Mysore (founded 1916). Nearby Chamundi Hill has  a monolith representing Nandi, the sacred bull of the Hindu deity Shiva.</p><p>Mysore See Karnataka</p><p>mystery play Vernacular drama of the Middle Ages. It developed from  the liturgical drama and usually represented a biblical subject. In the 13th  century, craft guilds began producing mystery plays at sites removed from  the church, adding apocryphal and satirical elements to the dramas. In  England groups of 25-50 plays were later organized into lengthy cycles,  such as the Chester plays and the Wakefield plays. In England the plays  were often performed on moveable pageant wagons, while in France and  Italy they were acted on stages with scenery representing heaven, earth,  and hell. Technical flourishes such as flying angels and fire-spouting dev�  ils kept the spectators� attention. The genre of the mystery play declined  by 1600. See also miracle play; morality play.</p><p>mystery religion Any of various secret cults of the Greco-Roman  world. Derived from primitive tribal ceremonies, mystery religions  reached their peak of popularity in Greece in the first three centuries ad.  Their members met secretly to share meals and take part in dances and  ceremonies, especially initiation rites. The cult of Demeter produced the  most famous of the mystery religions, the Eleusinian Mysteries, as well as  the Andania mysteries. Dionysus was worshiped in festivals that included  wine, choral singing, sexual activity, and mime. The Orphic cult, by con�  trast, based on sacred writings attributed to Orpheus, required chastity and  abstinence from meat and wine. Mystery cults also attached to Arris, Isis,  and Jupiter Dolichenus, among others.</p><p>mystery story Work of fiction in which the evidence related to a crime  or to a mysterious event is so presented that the reader has an opportu�  nity to consider solutions to the problem, the author�s solution being the  final phase of the piece. The mystery story is an age-old popular genre  and is related to several other forms. Elements of mystery may be present  in narratives of horror or terror, pseudoscientific fantasies, crime stories,  accounts of diplomatic intrigue, affairs of codes and ciphers and secret  societies, or any situation involving an enigma. See also detective story;  GOTHIC NOVEL.</p><p>mysticism Spiritual quest for union with the divine. Forms of mysti�  cism are found in all major religions. Hinduism, with its goal of absorp�</p><p>tion of the soul in the All, is inherently predisposed to mystical experience.  Buddhism emphasizes meditation as a means of moving toward nirvana. In  Islam, Sufism employs metaphors of intoxication and of the love between  bride and bridegroom to express the desire for union with the divine. In  Judaism, the foundations of mysticism were laid in the visions of the bib�  lical prophets and were later developed in the Kabbala and in Hasidism.  Mysticism has appeared intermittently in Christianity, notably in the writ�  ings of St. Augustine and St. Teresa of Avila, and in the works of Meister  Eckhart and his 14th-century successors.</p><p>myth Traditional story of ostensibly historical events that serves to  unfold part of the worldview of a people or explain a practice, belief, or  natural phenomenon. Myths relate the events, conditions, and deeds of  gods or superhuman beings that are outside ordinary human life and yet  basic to it. These events are set in a time altogether different from his�  torical time, often at the beginning of creation or at an early stage of pre�  history. A culture�s myths are usually closely related to its religious beliefs  and rituals. The modem study of myth arose with early 19th-century  Romanticism. Wilhelm Mannhardt, James George Frazer, and others later  employed a more comparative approach. Sigmund Freud viewed myth as  an expression of repressed ideas, a view later expanded by Carl Gustav  Jung in his theory of the �collective unconscious� and the mythical arche�  types that arise out of it. Bronislaw Malinowski emphasized how myth ful�  fills common social functions, providing a model or �charter� for human  behaviour. Claude Levi-Strauss discerned underlying structures in the for�  mal relations and patterns of myths throughout the world. Mircea Eliade  and Rudolf Otto held that myth is to be understood solely as a religious  phenomenon. Features of myth are shared by other kinds of literature.  Origin tales explain the source or causes of various aspects of nature or  human society and life. Fairy tales deal with extraordinary beings and  events but lack the authority of myth. Sagas and epics claim authority and  truth but reflect specific historical settings.</p><p>myxedema V.mik-so-'de-moX Physiological reaction to low levels of  thyroid hormone in adults, either due to thyroid-gland removal, lack of  function, or atrophy, or secondary to a pituitary-gland disorder. Gradual  changes include enlarged tongue, thick, puffy skin, drowsiness, cardiac  enlargement, and slow metabolism.

March 21, 1910, Paris) French photographer, caricatur�  ist, and writer. When his father�s bankruptcy forced him  to leave medical school in 1838, he settled in Paris and  began selling caricatures to humour magazines. By  1853 he had become an expert photographer and had  opened a portrait studio. His studies of prominent Pari�  sians such as Charles Baudelaire (1855) and Eugene Dela�  croix (1855) were exceptional in their naturalness, in  contrast to the stiff formality of most portraits of the  time. His studio became a favourite meeting place of  the Paris intelligentsia and was the site of the first Impres�  sionist exhibit. A tireless innovator, in 1855 he patented  the idea of using aerial photographs in mapmaking and  surveying, and in 1858 he himself made the first suc�  cessful aerial photograph, from a balloon. He also wrote  novels, essays, satires, and autobiographical works.</p><p>Nader, Ralph (b. Feb. 27, 1934, Winsted, Conn., U.S.) U.S. lawyer  and consumer advocate. The son of Lebanese immigrants, he attended  Princeton University and Harvard Law School. In 1963 he left his private  law practice in Hartford, Conn., to hitchhike to Washington, D.C., where  he began public interest work. His concern about unsafe car designs  resulted in the best-selling book Unsafe at Any Speed (1965), which led  directly to the passage of national auto-safety standards. Since then he  and his associates, known as �Nader�s Raiders,� have performed numer�  ous studies on consumer health, safety, and financial issues and have lob�  bied for greater government regulation of business and industry in a  variety of areas. He was instrumental in the passage of the Freedom of  Information Act (1966) and in establishing the Occupational Safety and  Health Administration (OSHA), the  Consumer Product Safety Commis�  sion, and the Environmental Protec�  tion Agency. He also founded the  consumer organization Public Citi�  zen and the U.S. Public Interest  Research Group, an umbrella orga�  nization for other public interest  research groups.

There he taught and studied the works of Zhu Xi, but eventually  he abandoned Zhu�s philosophy for the idealist thought of Wang Yang-  ming. Like Wang, he believed truth was to be discovered through intu�  ition and reflection rather than empirical investigation and that the  universe�s unifying principle exists in the human mind, not in the exter�  nal world.

Located on the southeastern bank of the Yangtze River (Chang  Jiang) northwest of Shanghai, the site has been inhabited for thousands  of years. The present city was founded in 1368 by the Ming dynasty, which  had its capital there (1368-1421). It was taken by the British in the Opium  Wars of 1842 and was largely destroyed in 1864 after having served (since  1853) as the capital of the Taiping revolutionaries. Nanjing was opened as  a treaty port in 1899 and was the Nationalist capital from 1928 to 1937;  it was then taken by the Japanese, and it was the site of the Nanjing Mas�  sacre in the Sino-Japanese War of 1937�45. It was occupied by commu�  nist forces in 1949 and became the provincial capital in 1952. Nanjing is  a port city and a major industrial and communications centre with a num�  ber of universities and colleges.

Aug. 15, 1769, Ajaccio, Corsica�d. May 5,  1821, St. Helena Island) French general and emperor (1804-15). Bom to  parents of Italian ancestry, he was educated in France and became an army  officer in 1785. He fought in the French Revolutionary Wars and was pro�</p><p>moted to brigadier general in 1793. After victories against the Austrians  in northern Italy, he negotiated the Treaty of Campo Formio (1797). He  attempted to conquer Egypt (1798-99) but was defeated by the British  under Horatio Nelson in the Battle of the Nile. The Coup of 18-19 Bru-  maire brought him to power in 1799, and he installed a military dictator�  ship, with himself as First Consul. He introduced numerous reforms in  government, including the Napoleonic Code, and reconstructed the French  education system. He negotiated the Concordat of 1801 with the pope.  After victory against the Austrians at the Battle of Marengo (1800), he  embarked on the Napoleonic Wars. The formation of coalitions of Euro�  pean countries against him led Napoleon to declare France a hereditary  empire and to crown himself emperor in 1804. He won his greatest mili�  tary victory at the Battle of Austerlitz against Austria and Russia in 1805.  He defeated Prussia at the Battles of Jena and Auerstedt (1806) and Rus�  sia at the Battle of Friedland (1807). He then imposed the Treaty of Tilsit  on Russia, ending the fourth coalition of countries against France. Despite  his loss to Britain at the Battle of Trafalgar, he sought to weaken British  commerce and established the Continental System of port blockades. He  consolidated his European empire until 1810 but became embroiled in the  Peninsular War (1808-14). He led the French army into Austria and  defeated the Austrians at the Battle of Wagram (1809), signing the Treaty  of Vienna. To enforce the Treaty of Tilsit, he led an army of about 600,000  into Russia in 1812, winning the Battle of Borodino, but was forced to  retreat from Moscow with disastrous losses. His army greatly weakened,  he was met by a strong coalition of allied powers, who defeated him at  the Battle of Leipzig (1813). After Paris was taken by the allied coalition,  Napoleon was forced to abdicate in 1814 and was exiled to the island of  Elba. In 1815 he mustered a force and returned to France to reestablish  himself as emperor for the Hundred Days, but he was decisively defeated  at the Battle of Waterloo. He was sent into exile on the remote island of  St. Helena, where he died six years later. One of the most celebrated fig�  ures in history, Napoleon revolutionized military organization and train�  ing and brought about reforms that permanently influenced civil  institutions in France and throughout Europe.</p><p>Napoleon II, duke von Reichstadt orig.

Emperor Francis II, rather than allow him  to remain in France as the focus of resistance as Napoleon II. Given the  Austrian title of duke of Reichstadt, he was controlled by Klemens, prince  von Metternich.

The  nephew of Napoleon, he spent his  youth in exile in Switzerland and  Germany (1815-30). With the death  in 1832 of Napoleon�s son,</p><p>Napoleon-Fran^ois-Charles-Joseph  Bonaparte, duke von Reichstadt, he  became the claimant to the French  throne. After an abortive coup d�etat,  he was exiled by King Louis- Philippe  to the U.S. After another attempted  coup (1840), he was arrested, tried,  and imprisoned. He escaped to  England (1846) and returned to Paris  (1848), where he was elected to the  national assembly. He evoked the  legend of Napoleon to win the popu�  lar vote as president of the Second  Republic. Attempting to expand his power, he staged a coup in 1851 and  made himself dictator; in 1852, as Napoleon III, he became emperor of  the Second Empire. Seeking to reestablish French power, he led France into  the Crimean War and helped negotiate the treaty at the Congress of Paris  (1856). He sided with Sicily against Austria (1859) and was victorious at  the Battle of Solferino.

He kept France neutral in the Austro-Prussian  War (1866), but in 1870 Otto von Bismarck contrived to involve France  in the disastrous Franco-Prussian War.

See also law code.</p><p>Napoleonic Wars (1799-1815) Series of wars that ranged France  against shifting alliances of European powers. Originally an attempt to  maintain French strength established by the French Revolutionary Wars,  they became efforts by Napoleon to affirm his supremacy in the balance  of European power. A victory over Austria at the Battle of Marengo (1800)  left France the dominant power on the continent. Only Britain remained  strong, and its victory at the Battle of Trafalgar (1805) ended Napoleon�s  threat to invade England. Napoleon won major victories in the Battles of  Ulm and Austerutz (1805), Jena and Auerstedt (1806), and Friedland (1807)  against an alliance of Russia, Austria, and Prussia. The resulting Treaties  of Tilsit (1807) and the Treaty of Schonbrunn (1809) left most of Europe  from the English Channel to the Russian border either part of the French  Empire, controlled by France, or allied to it by treaty. Napoleon�s suc�  cesses resulted from a strategy of moving his army rapidly, attacking  quickly, and defeating each of the disconnected enemy units. His enemies�  responding strategy was to avoid engagement while withdrawing, forcing  Napoleon�s supply lines to be overextended; the strategy was successfully  used against him by the duke of Wellington in the Peninsular War and by  Mikhail, Prince Barclay de Tolly, in Russia. In 1813 the Quadruple Alliance  formed to oppose Napoleon and amassed armies that outnumbered his.  Defeated at the Battle of Leipzig, he was forced to withdraw west of the  Rhine River, and after the invasion of France (1814) he abdicated. He  rallied a new army to return in the Hundred Days (1815), but a revived  Quadruple Alliance opposed him. His final defeat at the Battle of Water�  loo was caused by his inability to surprise and to prevent the two armies,  led by Wellington and Gebhard von Blucher, from joining forces to defeat  him. With his second abdication and exile, the era of the Napoleonic Wars  ended.</p><p>nappe \'nap\ In geology, a large body or sheet of rock that has been  moved by faulting or folding a distance of about 1 mi (1.5 km) or more  from its original position.

First identified by Havelock Ellis in  1898, the disorder is named for the mythological Narcissus, who fell in  love with his own reflection. In addition to an inflated self-image and  addiction to fantasy, narcissism is characterized by an unusual coolness  and composure, which is shaken only when the narcissistic confidence is  threatened, and by the tendency to take others for granted or to exploit  them. According to Sigmund Freud, narcissism is a normal stage in chil�  dren�s development, but it is considered a disorder when it occurs after  puberty.</p><p>Narcissus \nar-'si-sos\ In Greek mythology, a beautiful youth who fell  in love with his own reflection.

The  stem usually bears one large blos�  som. The central crown of each yel�  low, white, or pink flower ranges in  shape from the form of a trumpet, as  in the daffodil, to a ringlike cup, as in  the poet�s narcissus. Rushlike or flat�  tened leaves arise from the base of the  plant. Though poisonous, the bulbs were once used in medicines.</p><p>narcolepsy Sleep disorder with sudden, uncontrollable spells of day�  time sleep and disturbances of nighttime sleep.

Called Namade by the Greek geog�  rapher Ptolemy in the 2nd century ad, it has always been an important route  between the Arabian Sea and the Ganges River valley. It is a pilgrimage  route for Hindus who regard it their most sacred river after the Ganges.</p><p>Narodnik \na- , rod- l nik\ Russian Populist Member of a 19th-century  socialist movement in Russia. In the 1860s and �70s the movement  attracted intellectuals who believed that political propaganda among the  peasants {narod, �people�) would lead to their revolt and the liberaliza�  tion of the tsarist regime. Attempts to arouse the peasants produced police  persecution and arrests, which drove the socialists to more radical meth�  ods, including terrorism. The revolutionary group Land and Freedom, led  by Georgy Plekhanov, was formed in the mid-1870s and continued to work  among the peasantry until it split in 1879. The movement�s populist ide�  ology was revived in the 20th century by the Socialist Revolutionary Party.</p><p>Narragansett \,nar-3-'gan-s9t\ Bay Inlet of the Atlantic Ocean, south�  eastern Rhode Island, U.S. It extends north for 28 mi (45 km) into the  state, almost dividing it into two parts.

Since colonial times it has been an active  shipping centre; its chief ports are Providence and Newport. Much of the  bay�s area is devoted to fishing and recreation.</p><p>Narses \'nar-,sez\ (b. c. 480, Armenia�d. 574, probably Rome or Con�  stantinople) Byzantine general under Justinian I. A eunuch, he commanded  the imperial bodyguard and rose to become grand chamberlain. He helped  to quell a riot in 532 and save Justinian�s throne; his loyalty to the emperor  brought him into the confidence of the emperor�s wife Theodora. In 538  Narses was sent on a military expedition to retake Italy, but his inability  to cooperate with the commander allowed the Ostrogoths to triumph. He  returned to Italy in 551 and conquered the Ostrogothic kingdom. He held  power in Italy until removed by Justinian�s successor (567). It was  rumoured that Narses had invited the Lombards, who conquered much of  Italy, into the peninsula in retaliation for his dismissal.</p><p>narthex Long, narrow porch, usually colonnaded or arcaded, crossing  the entire width of a church at its entrance.

Narwhals are  mottled gray, attain a length of 11.5-16 ft (3.5-5 m), and have no dorsal  fin. They have only two teeth, at the upper jaw tip. The male�s left tooth  is a straight, protruding tusk, up to 8.9 ft (2.7 m) long, that is grooved on  the surface in a left-handed spiral. It was prized in medieval times as the  unicorn horn. The tusk is thought to have evolved as a sexual display.  Narwhals eat fishes, cephalopods, and crustaceans. They are hunted by  humans for their tusks and meat.

Its goals include improving human understanding of  the universe, the solar system, and Earth and establishing a permanent  human presence in space. NASA, previously the National Advisory Com�  mittee for Aeronautics (NACA), was created largely in response to the  Soviet Union�s launch of Sputnik in 1957. Its organization was well under  way in 1961, when Pres. John F. Kennedy proposed that the U.S. put a man</p><p>on the Moon by the end of the 1960s (see Apollo). Later unmanned pro�  grams (e.g., Viking, Mariner, Voyager, Galileo) explored other planets and  interplanetary space, and orbiting observatories (e.g., the Hubble Space  Telescope) have studied the cosmos. NASA also developed and launched  various satellites with Earth applications, such as Landsat and communi�  cations and weather satellites. It planned and developed the space shuttle  and led the development and construction of the International Space Sta�  tion.</p><p>NASDAQ Vnaz-dak\ in full National Association of Securities  Dealers Automated Quotations U.S. market for over-the-counter  securities. Established in 1971 by the National Association of Securities  Dealers (NASD), NASDAQ is an automated quotation system that reports  on the trading of domestic securities not listed on the regular stock  exchanges. It publishes two composite price indexes daily as well as bank,  insurance, transportation, utilities, and industrial indexes. By the 1990s it  had surpassed the American Stock Exchange (AMEX) to become the sec�  ond largest U.S. securities market, in terms of market capitalization, after  the New York Stock Exchange. Members register with the Securities and  Exchange Commission and meet requirements for assets, capital, public  shares, and shareholders. In 1999 it merged with AMEX to form the  Nasdaq-Amex Market Group, and in 2000 NASD sold nearly half its  interest in NASDAQ to private investors.

The two armies met near Naseby, south of  Leicester, and deployed along parallel ridges. The 10,000-man royalist  force under Prince Rupert drove back part of the Parliamentary cavalry  but then engaged in wild pursuit, leaving the royalist infantry exposed.  The more disciplined Parliamentary force under Oliver Cromwell  regrouped and counterattacked, routing the royalists and taking 4,000  prisoners. With the loss of his best soldiers, Charles could no longer meet  the New Model Army in open battle and effectively lost the war.</p><p>Naser od-DTn Shah See Nasir al-DIn Shah</p><p>Nash, John (b. 1752, London?, Eng.�d. May 13, 1835, Cowes, Isle  of Wight) British architect and city planner. From 1798 Nash was  employed by the Prince of Wales. Acquiring considerable wealth, he built  for himself East Cowes Castle, Isle of Wight (1798), which had much  influence on Gothic Revival architecture. He subsequently dotted England  and Ireland with castles, houses, and cottages in the Gothic or Italianate  style. Regent�s Park, London (1811), comprises a canal, lake, wooded  area, botanical garden, and, on the periphery, shopping arcades and pic�  turesque groupings of residences. In 1821 he began to reconstruct Buck�  ingham House, London, as a royal palace; dismissed before completing  the project, he faced an inquiry into its cost and structural soundness.  Nash�s East and West Park Villages, London (completed after his death  by his chief assistant, James Pennethome), served as models for �garden  suburbs� of separate houses informally arranged.</p><p>Nash, John Forbes (b.

In 1931  he published Hard Lines, the first of 20 collections that include The Bad  Parents� Garden of Verse (1936), I�m a Stranger Here Myself { 1938), and  Everyone but Thee and Me (1962). His audacious, quotable verse employs  delightfully impossible rhymes, puns, and ragged stanzas, often inter�  rupted by digressions. He wrote several children�s books and the lyrics  for the musicals One Touch of Venus (1943) and Two�s Company (1952).</p><p>Nashe \'nash\, Thomas (b. 1567, Lowestoft, Suffolk, Eng.�d. c.  1601, Yarmouth, Norfolk?)

During the American Civil War, it was occupied by  Federal troops (1862). The war�s last major battle (1864) took place outside  the city. It is a financial and commercial centre, producing shoes, clothing,  glass, and tires. Important industries include printing, publishing, and  recording. Well known for country and western music, it is the site of Opry-  land U.S.A. and the Country Music Hall of Fame and Museum.

Delegates from nine Southern states met in June 1850; though  extremists favoured secession, moderate Whigs and Democrats prevailed.  The group adopted 28 resolutions defending slavery but was willing to  allow an extension to the Pacific of the boundary established in the Mis�  souri Compromise. After the Compromise of 1850, a smaller group of del�  egates met in November; dominated by extremists, it denounced the  compromise and called again for secession.</p><p>Nasi, Lake or Lake Nasijarvi \'na-se-,yar-ve\ Lake, southwestern  Finland.

May 1, 1896, Tehran) Qajar dynasty  shah of Iran (1848-96) who began his reign as a reformer but became  increasingly conservative. Domestically, he curbed the power of the  clergy in secular affairs, introduced telegraph and postal services, built  roads, opened the first school offering education along Western lines, and  launched Iran�s first newspaper. Later in his rule, however, he steadfastly  refused to deal with the growing pressure for reforms. He granted a series  of concessionary rights to foreigners in return for large payments. Fore�  most among these was a 50-year concession given in 1890 on the pur�  chase, sale, and processing of all tobacco in the country, which led to a  national boycott of tobacco and the withdrawal of the concession the fol�  lowing year.

In 1045 he made a pilgrimage to Mecca and then traveled to Palestine and  Egypt, which was then ruled by the Shfite Fajimid dynasty. He returned to  his homeland to serve as a missionary for the Fatimid�s Isma'TlT sect of  Shl'ites, but his efforts aroused the hostility of the majority Sunnites and  he was obliged to flee.

The area was occupied for centuries by BANTU-speaking peoples. It was  given the name Natal by Vasco da Gama when he sighted the harbour of  Port Natal (now Durban) on Christmas Day (Portuguese Natal) in 1497.  The first European settlers arrived in 1824. In 1837 Afrikaners arrived in  the interior and, after they defeated the Zulu there, established the Repub�  lic of Natal. Annexed by the British in 1843, it was extended by numer�  ous acquisitions. During the South African War, Natal was invaded by  Afrikaner forces, which were checked by the British. In 1910 it became  a province of the Union of South Africa and in 1961 of the Republic of  South Africa. The fragmented, nonindependent black state, or homeland,  of KwaZulu was later created within Natal, which was the scene of clashes  by rival black factions (see African National Congress; Inkatha Freedom  Party).

It was  founded in 1931 by Wallace D. Fard, who established its first mosque in  Detroit, Mich. Fard retired into obscurity and his assistant Elijah Muham�  mad, who founded a second temple in Chicago, took over in 1934. He  asserted the moral and cultural superiority of Africans over whites and  urged African Americans to renounce Christianity as a tool of the oppres�  sors. His teachings also included the traditional Islamic tenets of mono�  theism, submission to God, and strong family life. The Nation of Islam  grew quickly after World War II, and in the early 1960s it achieved  national prominence through the work of Malcolm X. Leadership disputes  led Malcolm to form a separate organization and finally to his assassina�  tion in 1965. In the 1970s Elijah Muhammad was succeeded by his son,  Wallace D.

It was used again when the National Assembly of  1871-75 drafted a new constitution. In the Third Republic (1875-1940), the  name designated the two houses of parliament, the Senate and the Cham�  ber of Deputies. In the Fourth Republic (1946-58) and Fifth Republic (from  1958), the name was applied only to the lower house (the former Cham�  ber of Deputies).

National banks were created during the Civil War under the National Bank  Act of 1863 to combat financial instability caused by state banks and to  help finance the war effort. When these banks purchased federal bonds  and deposited them with the comptroller of the currency, they were per�  mitted to circulate national bank notes, thereby creating a stable, uniform  national currency. After the Civil War, the government began to retire the  bonds issued during the war, which reduced the number of national bank  notes that could be issued. Concern over the inflexibility of national bank  notes led to the formation of the Federal Reserve System in 1913, which all  national banks were required to join. The U.S. Treasury assumed the obli�  gation of issuing national bank notes in 1935, effectively ending the issue  of money by private commercial banks.</p><p>National Basketball Association (NBA) U.S. professional bas�  ketball league.

The West�</p><p>ern Conference consists of the Northwest Division (Denver Nuggets, Min�  nesota Timberwolves, Portland Trail Blazers, Seattle SuperSonics, Utah  Jazz), the Pacific Division (Golden State Warriors, Los Angeles Clippers,  Los Angeles Lakers, Phoenix Suns, Sacramento Kings), and the South�  west Division (Dallas Mavericks, Houston Rockets, Memphis Grizzlies,  New Orleans Hornets, San Antonio Spurs).</p><p>National Broadcasting Company See NBC</p><p>National Collegiate Athletic Association (NCAA) Organiza�  tion that administers U.S. intercollegiate athletics. It was formed in 1906  but did not acquire significant powers to enforce its rules until 1942.  Headquartered at Indianapolis, Ind., it functions as a general legislative  and administrative authority, formulating and enforcing rules of play for  various sports and eligibility criteria for athletes. It has about 1,200 mem�  ber schools and conducts about 80 national championships in a total of  about 20 sports.</p><p>National Convention French Convention Nationale Govern�  ing assembly (1792-95) of the French Revolution. Comprising 749 depu�  ties elected after the overthrow of the monarchy (1792), it sought to  provide a new constitution for France. The struggle between the radical  Montagnards and the moderate Girondins dominated the Convention until  the Girondins were purged in 1793. The democratic constitution already  approved by the Convention was not put into effect while the Monta�  gnards controlled the assembly (1793-94). After the Thermidorian Reac�  tion (1794), the balance of power in the Convention was held by members  of the Plain. The Girondins were recalled, and the Constitution of 1795  was approved for the Directory regime that replaced the Convention.</p><p>national debt or public debt Total indebtedness of a government,  especially as evidenced by securities issued to investors. The national debt  grows whenever the government operates a budget deficit�that is, when  government spending exceeds government revenues in a year. To finance  its debt, the government can issue securities such as bonds or treasury bills.  The level of national debt varies from country to country, from less than  10% of the gross domestic PRODUCT (GDP) to more than double it. Public  borrowing is thought to have an inflationary effect on the economy and  thus is often used during recessions to stimulate consumption, investment,  and employment. See also deficit financing; John Maynard Keynes.</p><p>National Education Association (NEA) Voluntary association of  U.S. teachers, administrators, and other educators associated with elemen�  tary and secondary schools and colleges and universities. Founded in 1857  as the National Teachers Assn., it is among the world�s largest profes�  sional organizations. Operating much like a labour union, it represents its  members through numerous state and local affiliates. It seeks to improve  the schools and working conditions, advance the cause of public educa�  tion, promote federal legislation, and sponsor research.</p><p>National Endowment for the Arts (NEA) Independent agency of  the U.S. government that supports the creation, dissemination, and per�  formance of the arts. It was created by the U.S. Congress in 1965 and  funds projects in literature, music, theatre, film, dance, fine arts, sculp�  ture, and crafts. The majority of NEA grants go directly to institutions  such as art museums, not-for-profit theatres, and symphony orchestras; to  arts programs in schools; and to support events such as folk arts festivals.  Some individual artists are funded for specific projects as well. Grants are  often awarded by the NEA in cooperation with state and local arts agen�  cies. NEA funding dropped in the 1990s, as Congressional opposition  arose in response to certain NEA-supported projects.</p><p>National Endowment for the Humanities (NEH) U.S. inde�  pendent agency. Founded in 1965, it supports research, education, pres�  ervation, and public programs in the humanities. It provides grants to  museums, libraries, archives, television programs, historic sites, transla�  tion and editorial projects by academic presses, educational and research  institutions, and individuals.</p><p>National Film Board of Canada (NFB) Canadian department of  film production. It was established in 1939 and directed by John Grier�  son (1898-1972), who developed the studio into a leading producer of  documentaries, including the World War II propaganda films Canada Car�  ries On and The World in Action. The studio also made high-quality ani�  mated movies by Norman McLaren (1914-87) and others, and it later  expanded to produce feature films, including The Luck of Ginger Coffey  (1964), The Apprenticeship of Duddy Kravitz (1974), and The Company  of Strangers (1990).</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1332 I National Football League &#x25BA; National League</p></section><section><p>L_</p><p>N</p><p>National Football League (NFL) Major professional football orga�  nization in the U.S. It was founded in 1920 at Canton, Ohio; its first presi�  dent was Jim Thorpe. In 1970 it merged with the rival American Football  League (founded 1959). Beginning with the 2002 season, it was divided  into two conferences, each with four divisions. The National Conference  consists of the East Division (Dallas Cowboys, New York Giants, Phila�  delphia Eagles, and Washington Redskins), the South Division (Atlanta  Falcons, Carolina Panthers, New Orleans Saints, and Tampa Bay Bucca�  neers), the North Division (Chicago Bears, Detroit Lions, Green Bay  Packers, and Minnesota Vikings), and the West Division (Arizona Cardi�  nals, St. Louis Rams, San Francisco Forty-Niners, and Seattle Seahawks).  The American Conference consists of the East Division (Buffalo Bills,  Miami Dolphins, New England Patriots, and New York Jets), the South  Division (Houston Texans, Indianapolis Colts, Jacksonville Jaguars, and  Tennessee Titans), the North Division (Baltimore Ravens, Cincinnati Ben-  gals, Cleveland Browns, and Pittsburgh Steelers), and the West Division  (Denver Broncos, Kansas City Chiefs, Oakland Raiders, and San Diego  Chargers). The league season culminates with the Super Bowl, the annual  championship game between the winners of the National and American  conferences.</p><p>national forest In the U.S., any of numerous forest areas under fed�  eral supervision for the purposes of conserving water, timber, wildlife,  fish, and other renewable resources and providing public recreation areas.  Administered by the U.S. Department of Agriculture�s Forest Service, in  the early 21st century the forests numbered 155 and occupied 352,000 sq  mi (911,700 sq km) in 40 states and Puerto Rico. They were founded in  1891 as a system of forest reserves and were renamed national forests in  1907.

Mellon  donated his collection of European paintings to the U.S. He also donated  funds to construct the gallery�s Neoclassical building, opened in 1941.  Now known as the West Building, it is connected by plaza and under�  ground concourse to the East Building, designed by I.M. Pei (completed  1978). The museum houses an extensive collection of U.S. and European  paintings, sculpture, decorative arts, and graphic arts from the 12th to 21st  centuries; especially well represented are works by Italian Renaissance,  17th-century Dutch, and 18th- and 19th-century French artists.</p><p>National Gallery of Canada National art museum founded in  Ottawa in 1880. Its holdings include extensive collections of Canadian art  as well as important European works. Its nucleus was formed with the  donation of diploma works by members of the Royal Canadian Academy.  In 1911 the drawing collection was formed (1913-24) with important  works by Albrecht DOrer and Rembrandt, and the photography collection  was begun in 1967. A new building opened in 1988; the Canadian Cen�  tre for the Visual Arts opened in 1991 and a multimedia learning centre  in 1996. The museum circulates several hundred exhibitions to other cit�  ies throughout the country each year.</p><p>National Geographic Society U.S. scientific society founded in  1888 in Washington, D.C., by a small group of eminent explorers and  scientists �for the increase and diffusion of geographic knowledge.� At  the turn of the 21st century it had approximately nine million members.  It has supported more than 7,000 major scientific projects and expedi�  tions, including those of Robert E. Peary, Richard E. Byrd, the Leakey family,  Jacques-Yves Cousteau, Jane Goodall, and Dian Fossey. It has published  numerous books, atlases, and bulletins and has created hundreds of tele�  vision documentaries. National Geographic Magazine is a monthly maga�  zine of geography, archaeology, anthropology, and exploration. It became  a leader in reproducing colour photographs and printing photographs of  undersea life, views from the stratosphere, and animals in their natural  habitats. It also became famous for articles containing substantial infor�  mation on environmental, social, and cultural aspects of the regions cov�  ered.

Every state and territory of the U.S. has a National Guard,  which can be called on by state governors during emergencies such as  riots and natural disasters. Guard units may also be ordered into active  duty for up to two years by the U.S. president in the event of a national  emergency. Enlistment in the National Guard is voluntary.</p><p>National Health Service (NHS) Comprehensive government  public-health service in Britain covering virtually the entire population,</p><p>established in 1946. Financed primarily by general taxes, most services  are free. General practitioners and dentists are paid per patient registered  with them and may also have private patients. Hospital and specialist ser�  vices are provided in government hospitals and other facilities by sala�  ried professionals. Local health authority services provide maternity and  child welfare, home nursing, and other preventive services. The NHS has  provided generally good health care at relatively low cost, but the increas�  ing expense of hospital stays has caused financial strain.</p><p>National Hockey League (NHL) Organization of professional  North American ice-hockey teams. The league was formed in 1917 by  five Canadian teams; the first U.S. team, the Boston Bruins, was added  in 1924. It today consists of 30 teams in two conferences and six divi�  sions. The Eastern Conference includes the Atlantic Division (New Jer�  sey Devils, New York Islanders, New York Rangers, Philadelphia Flyers,  and Pittsburgh Penguins), the Northeast Division (Boston Bruins, Buffalo  Sabres, Montreal Canadiens, Ottawa Senators, and Toronto Maple Leafs),  and the Southeast Division (Atlanta Thrashers, Carolina Hurricanes,  Florida Panthers, Tampa Bay Lightning, and Washington Capitals). The  Western Conference includes the Central Division (Chicago Blackhawks,  Columbus Blue Jackets, Detroit Red Wings, Nashville Predators, and St.  Louis Blues), the Northwest Division (Calgary Flames, Colorado Ava�  lanche, Edmonton Oilers, Minnesota Wild, and Vancouver Canucks), and  the Pacific Division (Mighty Ducks of Anaheim, Dallas Stars, Los Ange�  les Kings, Phoenix Coyotes, and San Jose Sharks). At the end of the regu�  lar winter season, the top teams in each division engage in a play-off for  the Stanley Cup.</p><p>national income accounting Set of principles and methods used to  measure a country�s income and production. There are two ways of mea�  suring national economic activity: the expenditure approach, which mea�  sures the money value of the total output of goods and services in a given  period (usually a year); and the income approach, which measures the  total income derived from economic activity after allowing for capital  consumption. The most commonly used indicator of national output is the  gross domestic product (GDP). National income may be derived from gross  national product (GNP) by making allowances for certain non-income  costs included in the GNP, such as indirect taxes, subsidies, and deprecia�  tion. National income thus calculated represents the aggregate income of  the owners of the factors of production; it is the sum of wages, salaries,  profits, interest, dividends, rent, and so on. The data accumulated for cal�  culating the GDP and national income may be manipulated in various  ways to show various relationships in the economy. Common uses of the  data include breakdowns of GDP according to type of product, break�  downs of national income by type of income, and analyses of the sources  of financing (e.g., personal savings, company funds, or national deficits).</p><p>National Institutes of Health (NIH) U.S. government agency that  conducts or supports biomedical research. It is made up of numerous spe�  cialized institutes (e.g.. National Cancer Institute; National Heart, Lung,  and Blood Institute; National Institute on Aging; National Institute of  Child Health and Human Development; and National Institute of Mental  Health). Part of the Department of Health and Human Services, it also  trains health researchers; disseminates information; and maintains other  offices and divisions, the National Library of Medicine (the foremost  source of medical information in the U.S.), and several research centres.</p><p>National Labor Relations Act See Wagner Act</p><p>National Labor Relations Board (NLRB) U.S. government  agency charged with administering the National Labor Relations Act  (1935). The three-member NLRB, appointed by the president, organizes  elections to determine whether employees wish to be represented by a  labour union in COLLECTIVE bargaining and monitors labour practices by  employers and unions. It does not initiate investigations; its involvement  must be sought by employers, individuals, or unions. Though it lacks  enforcement power for its orders, it can prosecute cases in court.</p><p>National League (NL) Oldest existing U.S. major-league profes�  sional baseball organization. The league was founded in 1876. Its  supremacy was challenged by several rival organizations over the years,  of which only the American League has survived; beginning in 1903, the  champions of the two leagues have engaged in an annual World Series  competition. Today the National League consists of 16 teams aligned in  three divisions. In the Eastern Division are the Atlanta Braves, Florida  Marlins (Miami), New York Mets, Philadelphia Phillies, and Washington  (D.C.) Nationals. In the Central Division are the Chicago Cubs, Cincin-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>National Liberal Party &#x25BA; National Socialism I 1333</p><p>nati Reds, Houston Astros, Milwaukee Brewers, Pittsburgh Pirates, and  St. Louis Cardinals. In the Western Division are the Arizona Diamond-  backs (Phoenix), Colorado Rockies (Denver), Los Angeles Dodgers, San  Diego Padres, and San Francisco Giants.</p><p>National Liberal Party German Nationalliberale Partei</p><p>Political party that was active first in Prussia and the North German Con�  federation from 1867, then in Germany in 1871-1918. From 1871 until  1879 the National Liberals, under the leadership of Rudolf von Bennig-  sen and Johannes von Miquel, enthusiastically supported Chancellor Otto  von Bismarck in the Reichstag (parliament) and constituted a virtual gov�  ernment party, winning more seats than any other party. After losing many  seats in the election of 1879, the party split over the issue of giving the  Reichstag control over revenues. It formed a coalition with the Conser�  vatives in 1890, but its influence waned thereafter.</p><p>National Liberation Front Title used by nationalist, usually social�  ist, movements in various countries since World War II. In Greece, the  National Liberation Front-National Popular Liberation Army was a  communist-sponsored resistance group that operated in occupied Greece  during the war. In Vietnam, the National Front for the Liberation of the  South was formed in 1960 to overthrow the South Vietnamese govern�  ment (see Viet Minh). In Algeria, the National Liberation Front, successor  to the body that directed Algeria�s war of independence (1954-62), was  the only constitutionally legal party from 1962 to 1989. In Uruguay, the  leftist guerrilla Tupamaro National Liberation Front (1963) battled police  and the army from 1967 to 1972; it later became a legal political party.  In the Philippines, the Moro National Liberation Front (1968) espoused  separatism for the Moros; during the last three decades of the 20th cen�  tury, its insurgency resulted in about 100,000 deaths. The Corsican  National Liberation Front (1976), the largest and most violent Corsican  nationalist movement, remained active into the 21st century. See also  Sandinistas.</p><p>national monument In the U.S., any of numerous areas reserved by  the federal government for the protection of objects or places of histori�  cal, scientific, or prehistoric interest. They include natural physical fea�  tures, remains of Indian cultures, and places of historical importance. In  1906 Pres. Theodore Roosevelt established the first national monument,  Devils Tower, in Wyoming. They are administered by the National Park  Service of the U.S. Department of the Interior.</p><p>National Organization for Women (NOW) U.S. women�s  rights organization. It was founded in 1966 by Betty Friedan to promote  equal rights for women, particularly in the area of employment. With some  500,000 members (both women and men) and 550 chapters, it addresses,  through lobbying and litigation, issues such as child care, pregnancy  leave, and abortion and pension rights. In the 1970s its major concern  was passage of the Equal Rights Amendment to the Constitution, though  the amendment failed in 1982. NOW has been more successful at the state  level, where it has lobbied for state equal rights amendments and  comparable-worth (equal pay for equal work) legislation.</p><p>national park Area set aside by a national government for the pres�  ervation of its natural environment. Most national parks are kept in their  natural state. Those in the U.S. and Canada emphasize land and wildlife  preservation, those in Britain focus mainly on the land, and those in Afri�  can nations focus primarily on animals. The world�s first national park,  Yellowstone, was established in the U.S. by Pres. Ulysses S. Grant in 1872.  Canada�s first national park, Banff, was established in 1885. Japan and  Mexico established their first national parks in the 1930s; Britain�s  national parks date to 1949. The U.S. National Park Service, established  in 1916, now also manages national monuments, preserves, recreation  areas, and seashores, as well as lakeshores, historic sites, parkways, sce�  nic trails, and battlefields. See also national forest.</p><p>National Party in full National Party of South Africa South  African political party that ruled the country in 1948-94. Its following  included most Afrikaners and many English-speaking whites. It was  founded in 1914 by J.B.M. Hertzog as the National Party of South Africa  and sought to rally Afrikaners against the Anglicizing policies of the gov�  ernment of Louis Botha and Jan Smuts. After winning the 1948 elections,  the party enacted a mass of racial legislation, a policy that the party named  apartheid. In 1961 it severed ties with the Commonwealth and made South  Africa a republic. In the 1990s, under F.W. de Klerk of the National Party,  the government began to repeal racially discriminatory laws. The National  Party was defeated in South Africa�s first universal elections in 1994 but</p><p>participated in a coalition government with its longtime rival, the African  National Congress. With the enactment of a new constitution in 1996, the  Nationalists resigned from the government in protest, marking their first  time out of government since 1948. In 1998 the party changed its name  to the New National Party. After several years of declining popularity, in  2005 the party�s federal council voted in favour of disbanding the party.

It was  established by the Corporation for Public Broadcasting in 1970 to pro�  vide programming to U.S. noncommercial and educational radio stations.  While initially providing programs on the arts, after 1983 the network  focused largely on news programming. It features the daily programs  Morning Edition and All Things Considered, as well as the interview pro�  grams Fresh Air and Talk of the Nation.</p><p>National Recovery Administration (NRA) (1933-35) U.S. gov�  ernment agency established to stimulate business recovery during the  Great Depression. As part of the National Industrial Recovery Act (1933),  the NRA established codes to eliminate unfair trade practices, reduce  unemployment, and set minimum wages and maximum hours. The U.S.  Supreme Court invalidated the act in 1935 because it gave quasi�  legislative powers to the executive branch. Many of its provisions  appeared in subsequent legislation.</p><p>National Republican Parly U.S. political party formed after the  Jeffersonian Republicans split in 1825. The National Republicans  included followers of John Quincy Adams and Henry Clay and opponents  of Andrew Jackson. Adams, the incumbent president, ran as the party�s  unsuccessful candidate in the 1828 presidential election. Its 1832 presi�  dential nominee was Clay, whose platform endorsing a high tariff, inter�  nal improvements, and the Bank of the United States (see Bank War). After  losing again to Jackson, the party joined with conservatives and other  anti-Jackson forces to form the Whig Party.</p><p>National Rifle Association (NRA) Governing organization for the  sport of shooting with rifles and pistols. It was founded in Britain in 1860.  The U.S. organization, formed in 1871, has a membership of some four  million. Both the British and the U.S. groups sponsor regional and  national shooting competitions and offer gun safety programs. The U.S.  NRA, one of the most powerful political lobbies in the country, has vig�  orously opposed many legislative proposals for the control of firearms.</p><p>National Security Agency (NSA) U.S. intelligence agency respon�  sible for cryptographic and communications intelligence and security.  Established in 1952 by a presidential directive (not by law), it has oper�  ated largely without Congressional oversight. Its director has always been  a general or an admiral. Its mission includes the protection and formu�  lation of codes, ciphers, and other cryptology as well as the interception,  analysis, and solution of coded transmissions. It conducts research into  all forms of electronic transmission and operates listening posts around  the world for the interception of signals. A target for penetration by for�  eign intelligence services, until recently it maintained no contact with the  public or the press. Though its budget and the number of its employees  is secret, the NSA is acknowledged to be far larger than the Central Intel�  ligence Agency, possessing financial resources that rival those of the  world�s largest companies.</p><p>National Security Council (NSC) U.S. agency that advises the  president on domestic, foreign, and military policies related to national  security. With the Central Intelligence Agency, it was established by the  1947 National Security Act. It provides the White House with a foreign-  policy-making instrument independent of the State Department. It has  four members�the president, vice president, and secretaries of state and  defense�and its staff is headed by the national security adviser.</p><p>National Socialism or Nazism Totalitarian movement led by Adolf  Hitler as head of Germany�s Nazi Party (1920-45). Its roots lay in the tra�  dition of Prussian militarism and discipline and German Romanticism,  which celebrated a mythic past and proclaimed the rights of the excep�  tional individual over all rules and laws. Its ideology was shaped by Hit�  ler�s beliefs in German racial superiority and the dangers of communism.  It rejected liberalism, democracy, the rule of law, and human rights, stress�  ing instead the subordination of the individual to the state and the neces�  sity of strict obedience to leaders. It emphasized the inequality of  individuals and �races� and the right of the strong to rule the weak.

Before  the era of the nation-state, the primary allegiance of most people was to  their immediate locality or religious group. The rise of large, centralized  states weakened local authority, and society�s increasing secularization  weakened loyalty to religious groups, though shared religion�along with  common ethnicity, political heritage, and history�is one of the factors  that draws people together in nationalist movements. Early nationalist  movements in 18th- and early 19th-century Europe were liberal and inter�  nationalist, but they gradually became more conservative and parochial.  Nationalism is considered a major contributing cause of World War I,  World War II, and many other wars of the modern era. In Africa and Asia  in the 20th century, nationalist movements often arose in opposition to  colonialism. After the fall of the Soviet Union, powerful nationalist sen�  timents in eastern Europe and the former Soviet republics contributed to  ethnic conflicts, such as those in the territories of the former Yugoslavia.</p><p>Nationalist Party or Kuomintang or Guomindang</p><p>Vgwo-'min-'darjV Political party that governed all or part of mainland  China from 1928 to 1949 and subsequently ruled Taiwan. Founded by  Song Jiaoren (1882-1913) and led by Sun Yat-sen, it evolved from a revo�  lutionary league working to overthrow the Qing dynasty into a political  party. In the early 1920s the party received guidance from the Soviet Bol�  shevik party; until 1927 it collaborated with the Chinese Communist Party.  Sun�s program, which stressed nationalism, democracy, and people�s live�  lihood, was ineffectively implemented by his successor, Chiang Kai-shek,  who became increasingly conservative and dictatorial. During World War  II, Chiang focused on suppressing the Chinese communists at the expense  of defending the country from the Japanese; in 1949 the Nationalists were  driven from the mainland to Taiwan. There they maintained a monopoly  on political power until 1989, when the first legal opposition party won  seats in the legislature. The first non-Nationalist president was elected in  2000. See also Wang Jingwei.</p><p>nationality Affiliation with a particular nation or sovereign state.  People, business coiporations, ships, and aircraft all have nationalities.  Nationality is inferior to citizenship, insofar as the latter implies a full set  of political privileges and the former does not. Countries have limited  rights to determine which of their inhabitants will be their nationals.  People generally acquire a nationality by birth within a particular coun�  try�s territory, by inheritance from one or both parents, or by naturaliza�  tion. It may change or be augmented or taken away if a country cedes  control of the territory where one lives to another country.</p><p>Nations, Battle of the See Battle of Leipzig  Native American See American Indian</p><p>Native American arts Literary, performing, and visual arts of the  indigenous peoples of the Western Hemisphere. Folktales have long been  a part of the social and cultural life of diverse groups of American Indian  and Inuit peoples. These tales were passed on orally by storytellers whose  presentation could shape the power of a story. One technique they fre�  quently employed was the repetition of incidents. Elements of  mythology�which vary from region to region�are also central. Any  definition of a Native American musical style is complicated by the vari�  ety between tribes and within tribal repertoires. An evident feature of  much music is male dominance. Equally evident is its limitation to a single  singer, who performs without harmonization and with percussion accom�  paniment. The singing voice is well supported from the diaphragm and  has a pulsating quality caused by the rhythmic expulsion of breath. Melo�  dies are generally sparse, sometimes even monotone; only rarely do songs  expand beyond the notes of the pentatonic (five-tone) scale. Among the  instruments used are drums, rattles, and sometimes wind instruments such  as the panpipe. The dances of Native American peoples represent forms  passed down over centuries and modified through interaction with foreign  and other Indian cultures. Their origins lie in religious rites; in attempts  to invoke magic and thus cure illness or assure success in food produc�  tion, hunting, and warfare; and in such life-passage rites as birth, puberty,  and death. Patterns within the dance reflect complex relations of rank and  gender, and the dancers themselves often represent different religious  symbols. Characteristic of Indian dancers is a slightly forward-tilted pos�  ture, forward raising of the knee, flat-footed stamp or toe-heeled action,  and tendencies towards muscular restraint and relaxation in gesture.</p><p>Native American visual arts also vary widely from tribe to tribe and region  to region. The particular utilitarian form that Native American art took on  often reflected the social organization of the cultures involved; for  example, political and military societies found their major art forms in  weaponry, pageantry of costume, and panoply. Working with the materi�  als natural to their respective homelands, the various Indian cultures also  produced art that reflected their environment; for example, those living  in forested regions became gifted sculptors in wood. Some of the best  Native American artwork was applied to those objects intended to please  a deity, soothe the angry gods, and placate or frighten evil spirits. Among  the many media explored by Native American cultures are weaving, pot�  tery, basketry, wooden sculpture, clay ware, quillwork, embroidery, beadwork,  totem poles, murals, and masks. Architectural achievements are also varied  and include the monumental stone cliff dwellings of the American South�  west and the enormous Pyramid of Quetzalcoatl at Cholula in Mexico.

Peyote was first  used to induce supernatural visions in Mexico in pre-Columbian times;  its use extended north into the Great Plains in the 19th century, and pey�  otism is now practiced among more than 50 tribes. Peyotist beliefs, which  combine Indian and Christian elements, vary from tribe to tribe. They  involve worship of the Great Spirit, a supreme deity who deals with  humans through various other spirits. In many tribes peyote is personi�  fied as Peyote Spirit and is associated with Jesus. The rite often begins on  Saturday evening and continues through the night. The Peyote Road is a  way of life calling for brotherly love, family care, self-support through  work, and avoidance of alcohol.</p><p>Native Dancer (foaled 1950) U.S. Thoroughbred racehorse.

He won 21 of 22  total starts, achieving widespread popularity as the first horse whose major  victories were seen on national television.</p><p>native element Any of the 19 chemical elements that occur as min�  erals and are found in nature uncombined with other elements. They are  commonly divided into three groups: metals (platinum, iridium, osmium,  iron, zinc, tin, gold, silver, copper, mercury, lead, chromium); semimet�  als (bismuth, antimony, arsenic, tellurium, selenium); and nonmetals (sul�  fur, carbon). Members of the group of native elements form under widely  varying physicochemical conditions and in very different rock types.  Many deposits are sufficiently abundant to be commercially important.</p><p>NATO in full North Atlantic Treaty Organization International  military alliance created to defend western Europe against a possible  Soviet invasion. A 1948 collective-defense alliance between Britain,  France, The Netherlands, Belgium, and Luxembourg was recognized as  inadequate to deter Soviet aggression, and in 1949 the U.S. and Canada  agreed to join their European allies in an enlarged alliance. A centralized  administrative structure was set up, and three major commands were  established, focused on Europe, the Atlantic, and the English Channel  (disbanded in 1994). The admission of West Germany in 1955 led to the  Soviet Union�s creation of the opposing Warsaw Treaty Organization, or  Warsaw Pact. France withdrew from military participation in 1966. Since  NATO ground forces were smaller than those of the Warsaw Pact, the  balance of power was maintained by superior weaponry, including  intermediate-range nuclear weapons. After the Warsaw Pact�s dissolution  and the end of the Cold War in 1991, NATO withdrew its nuclear weap�  ons and attempted to transform its mission. It involved itself in the Bal�  kan conflicts of the 1990s. Article 5 of the North Atlantic Treaty stated  that an attack on one signatory would be regarded as an attack on the rest.  This article was first invoked in 2001 in response to the terrorist Septem�  ber 11 attacks against the U.S. Additional countries joined NATO in 1999  and 2004 to bring the number of full members to 26.</p><p>Natsume Soseki Yna-tsu-'ma-'so-.se-keN known as Soseki orig.  Natsume Kinnosuke (b. Feb. 9, 1867, Edo, Japan�d. Dec. 9, 1916,  Tokyo) Japanese novelist. Originally a teacher, Natsume made his liter�  ary reputation with two very successful comic novels, I Am a Cat (1905-  06) and Botchan (1906). After 1907 he gave up teaching and produced  sombre works dealing with human attempts to escape from loneliness,  including The Wayfarer (1912-13), The Gate (1910), Kokoro (1914), and</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>natural bridge &#x25BA; Naucratis I 1335</p><p>Grass on the Wayside (1915).

Most are erosion features that occur in sandstone or  limestone. Some are formed by the collapse of part of a cavern roof. Oth�  ers may be produced by entrenched rivers eroding through meander necks  to form cutoffs. Still others are produced by exfoliation (separation of  successive thin shells) and may be enlarged by wind erosion.</p><p>Natural Bridges National Monument National monument,  southeastern Utah, U.S. Comprising three large natural bridges carved by  two winding streams, it was established in 1908. The largest bridge,  Sipapu, is 222 ft (68 m) high and spans 261 ft (80 m). Pictographs were  carved on another of the bridges, Kachina, by early cliff dwellers.</p><p>natural childbirth Any of the systems (e.g., the Lamaze method) of  managing birth without drugs or surgery. All begin with classes to teach  pregnant women about the birth process, including when to push and what  breathing and relaxation techniques to use at which stage. The goal is to  reduce fear and muscle tension, which can increase the pain of labour,  and to make the mother an active participant in the process. The father  or another partner usually attends the classes with the mother and coaches  her during the birth. See also midwifery; obstetrics and gynecology.</p><p>natural gas Colourless, highly flammable gaseous hydrocarbon con�  sisting primarily of methane and ethane. It may also contain heavier  hydrocarbons, carbon dioxide, hydrogen, hydrogen sulfide, nitrogen,  helium, and argon. It commonly occurs in association with crude oil (see  petroleum). Natural gas is extracted from wells drilled into the Earth. Some  natural gas can be used as it comes from the well, without any refining,  but most requires processing. It is transported either in its natural gaseous  state by pipeline or, after liquefaction by cooling, by tankers. Liquefied  natural gas occupies only about 1/600 of the volume of the gas. It has  grown steadily as a source of energy since the 1930s.</p><p>natural law In jurisprudence and political philosophy, a system of right  or justice common to all humankind and derived from nature rather than  from the rules of society, or positive law. The concept can be traced to  Aristotle, who held that what was �just by nature� was not always the  same as what was �just by law.� In one form or another, the existence of  natural law was asserted by the Stoics (see Stoicism), Cicero, the Roman  jurists, St. Paul, St. Augustine, Gratian, St. Thomas Aquinas, John Duns  Scotus, William of Ockham, and Francisco SuArez. In the modern period,  Hugo Grotius insisted on the validity of natural law even on the assump�  tion that God does not exist, and Thomas Hobbes defined a law of nature  as �a precept of general rule found out by reason, by which a man is for�  bidden to do that which is destructive of his life.� Hobbes attempted to  construct an edifice of law by rational deduction from a hypothetical �state  of nature� and a social contract of consent between rulers and subjects.  John Locke departed from Hobbes in describing the state of nature as an  early society in which free and equal men observe the natural law. Jean-  Jacques Rousseau postulated a savage who was virtuous in isolation and  actuated by two principles �prior to reason�: self-preservation and com�  passion. The authors of the U.S. Declaration of Independence refer only  briefly to �the Laws of Nature� before citing equality and other �unalien�  able� rights as �self-evident.� The French Declaration of the Rights of AAan  and of the Citizen asserts liberty, property, security, and resistance to  oppression as �imprescriptible natural rights.� Interest in the concept of  natural law declined dramatically in the 19th century, partly as a result  of skeptical attacks by Jeremy Bentham and other proponents of utilitarian�  ism; it was revived in the mid-20th century in light of the crimes commit�  ted by the Nazi regime during World War II. Skepticism of natural law  and natural rights remained strong, however, and later writers almost  invariably talked of human rights rather than natural rights.</p><p>natural selection Process that results in adaptation of an organism to  its environment by means of selectively reproducing changes in its geno�  type. Variations that increase an organism�s chances of survival and pro�  creation are preserved and multiplied from generation to generation at the  expense of less advantageous variations. As proposed by Charles Darwin,  natural selection is the mechanism by which evolution occurs. It may arise  from differences in survival, fertility, rate of development, mating suc�  cess, or any other aspect of the life cycle. Mutation, gene flow, and genetic  drift, all of which are random processes, also alter gene abundance. Natu�  ral selection moderates the effects of these processes because it multiplies</p><p>the incidence of beneficial mutations over generations and eliminates  harmful ones, since the organisms that carry them leave few or no descen�  dants. See also selection.</p><p>naturalism Aesthetic movement of the late 19th to early 20th century.  The movement was inspired by the principles and methods of natural sci�  ence, especially Darwinism, which were adapted to literature and art. In  literature, naturalism extended the tradition of realism, aiming at an even  more faithful, pseudoscientific representation of reality, presented with�  out moral judgment. Characters in naturalistic literature typically illus�  trate the deterministic role of heredity and environment on human life.  The movement originated in France, where its leading exponent was Emile  Zola. In America it is associated with the work of writers such as Stephen  Crane and Theodore Dreiser. Visual artists associated with naturalism chose  themes from life, capturing subjects unposed and not idealized, thus giv�  ing their works an unstudied air. Following the lead of the Realist painter  Gustave Courbet, painters chose themes from contemporary life, and many  deserted the studio for the open air, finding subjects among peasants and  tradespeople, capturing them as they found them. As a result, finished  canvases had the freshness and immediacy of sketches. Zola, the spokes�  man for literary naturalism, was also the first to champion Edouard Manet  and the Impressionists (see Impressionism). While naturalism was short�  lived as a historical movement, it contributed to art an enrichment of real�  ism, new areas of subject matter, and a largeness and formlessness that  was closer to life than to art. Its multiplicity of impressions conveyed the  sense of a world in constant flux.</p><p>naturalism In philosophy, the theory that affirms that all beings and  events in the universe are natural and therefore can be fully known by the  methods of scientific investigation. Though naturalism has often been  equated with materialism, it is much broader in scope. Strictly speaking,  naturalism has no ontological bias toward any particular set of categories  of reality: dualism and monism, atheism and theism, idealism and materialism  are all compatible with it. Naturalism was most influential in the 1930s  and �40s, chiefly in the U.S. among philosophers such as F.J.E. Wood-  bridge (1867-1940), Morris R. Cohen (1880-1947), John Dewey, Ernest  Nagel (1901-85), Sidney Hook (1902-89), and W.V.O. Quine.</p><p>naturalistic fallacy Fallacy of treating the term �good� (or any  equivalent term) as if it were the name of a natural property. In 1903 G.E.  Moore presented in Principia Ethica his �open-question argument�  against what he called the naturalistic fallacy, with the aim of proving that  �good� is the name of a simple, unanalyzable quality, incapable of being  defined in terms of some natural quality of the world, whether it be �plea�  surable� (John Stuart Mill) or �highly evolved� (Herbert Spencer). Since  Moore�s argument applied to any attempt to define good in terms of  something else, including something supernatural such as �what God  wills,� the term �naturalistic fallacy� is not apt. The open-question argu�  ment turns any proposed definition of good into a question (e.g., �Good  means pleasurable� becomes �Is everything pleasurable good?�)�  Moore�s point being that the proposed definition cannot be correct,  because if it were the question would be meaningless.</p><p>naturalization Process of granting nationality or citizenship to an alien. It  may be granted after voluntary application or through legislation, marriage  to a citizen, or parental action. Involuntary naturalization occurs when  one�s home territory is annexed by a foreign state. Qualifications for natu�  ralization may include a minimum residency period, a minimum age, law-  abiding character, good health, self-sufficiency, satisfactory knowledge of  the new country, and willingness to give up one�s former nationality.</p><p>Nature Conservancy Nonprofit organization dedicated to environ�  mental conservation and the preservation of biodiversity, founded in 1951,  that operates the largest private system of nature sanctuaries in the world.  It owns and manages more than 1,500 preserves throughout the U.S.,  comprising more than 9 million acres (3.8 million hectares) of ecologi�  cally significant land, and has expanded into Latin America and the  Pacific. Government-administered programs identify the relative abun�  dance of plant and animal species and the habitats they need to survive,  and the Conservancy then acquires�through gifts, exchanges, easements,  debt-for-nature swaps, purchases, and other nonconfrontational  arrangements�areas that are home to threatened species.</p><p>nature/nurture controversy See behaviour genetics</p><p>Naucratis Vno-kro-tosX Ancient Greek settlement, in Egypt�s Nile River  delta.

Area: 8 sq mi (21 sq km).  Population (2005): 10,200. Capital: Yaren (district). About two-thirds of  the population are indigenous Nauruans. Languages: Nauruan, English.  Religion: Christianity (mostly Protestant; also Roman Catholic). Currency:  Australian dollar. Nauru is a coral island with a central plateau 100-200 ft  (30-60 m) high. A thin strip of fertile land encircling the island is the major  zone of human settlement. It lacks harbours; ships must anchor to buoys  beyond a reef. Nauru once had the world�s largest concentration of phos�  phate, and its economy was based on phosphate mining and processing;  however, the deposits have been depleted, and the economy has been con�  verting to fishing and other ventures. Nauru is a republic with one legisla�  tive house; its head of state and government is the president. It was  inhabited by Pacific Islanders when the first British explorers arrived in  1798 and named it Pleasant Island because of their friendly welcome.  Annexed by Germany in 1888, it was occupied by Australia at the start of  World War I, and in 1919 it was placed under a joint mandate of Britain,  Australia, and New Zealand. During World War II it was occupied by the  Japanese. Made a UN trust territory under Australian administration in  1947, Nauru gained complete independence in 1968 and became a full  member of the Commonwealth and the UN in 1999.</p><p>nausea Discomfort in the pit of the stomach associated with disgust for  food and a feeling that vomiting will follow, as it often does. Nausea results  from irritation of nerve endings in the stomach or duodenum, which  stimulate brain centres that control nausea and vomiting. Nausea can be  a symptom of minor or serious disorders. Common causes include indi�  gestion (from eating too fast or from stress around mealtime), food poi�  soning, motion sickness, and pregnancy (morning sickness). Nausea may  also arise from any cause of abnormal lack of appetite (e.g., shock, pain,  influenza, badly fitting dentures, liver or kidney disease). Simple nausea  often is relieved by vomiting.</p><p>nautilus \'no-t 3 l-3s\ Either of two genera of cephalopods. The pearly, or  chambered, nautilus (genus Nauti�  lus) lives in the outermost chamber  of its smooth, coiled, usually  36-chambered shell, about 10 in. (25  cm) in diameter. A connecting tube  adjusts the gases in the chambers,  allowing the shell to act as a float.</p><p>Nautiluses search the ocean bottom  for shrimp or other prey, which they  capture with up to 94 small, sucker�  less, contractile tentacles. The paper  nautilus (genus Argonauta) feeds on  plankton near the surface of tropical  and subtropical seas. The female  resembles an octopus but has a thin,  unchambered, coiled shell, 12-16 in.</p><p>(30-40 cm) in diameter. The much  smaller male has no shell.</p><p>Nautilus Any of at least three his�  toric submarines. Robert Fulton built one of the earliest submersible craft  in 1800 in France; his Nautilus had a collapsible mast and sail for sur�  face propulsion and a hand-turned propeller for power. Andrew Campbell  and James Ash of Britain built a Nautilus submarine driven by battery-  powered electric motors in 1886. The name was also chosen for the  world�s first nuclear-powered submarine, launched by the U.S. Navy in  1954. Capable of longer submersion than any previous submarine, it made  a historic trip under the ice cap of the North Pole from Point Barrow,  Alaska, to the Greenland Sea in 1958.</p><p>Navajo Vna-v3-,ho\ or Navaho North American Indian people living  mostly in northwestern New Mexico, Arizona, and southeastern Utah,  U.S. The Navajo speak an Athabaskan language related to that of the  Apache. The Navajo and Apache migrated from Canada to the Southwest  c. ad 900-1200, after which the Navajo came under the influence of the  Pueblo Indians. Painted pottery and the famous Navajo rugs, as well as  sandpainting, are products of this influence. The craft of silversmithing</p><p>probably came from Mexico in the mid-19th century. The traditional  economy was based on farming and later herding of sheep, goats, and  cattle. The basic social unit was the band. Religion focused on the emer�  gence of the first people from worlds beneath the Earth�s surface. In 1863  the U.S. government ordered Col. Kit Carson to put an end to Navajo and  Apache raiding; his offensives resulted in the incarceration of about 8,000  Navajo and the destruction of crops and herds. Today many Navajo live  on or near the Navajo Reservation (24,000 sq mi [64,000 sq km] in New  Mexico, Arizona, and Utah); thousands earn their living as transient work�  ers. Their language has been tenaciously preserved; they used it to great  effect during World War II by transmitting coded messages in Navajo.  The Navajo are the most populous Native American group in the U.S.,  with about 270,000 individuals claiming sole Navajo descent in the 2000  U.S. census.</p><p>Navajo National Monument National monument, northern Ari�  zona, U.S. Covering 360 acres (146 hectares), it comprises three historic  cliff dwellings: Betatakin (Navajo: �Ledge House�), Keet Seel (�Broken  Pottery�), and Inscription House, among the best-preserved and most  elaborate cliff dwellings known. The largest, Keet Seel, was first discov�  ered by whites in 1895; the three sites were made a national monument  in 1909. The dwellings were the principal home of the Kayenta Anasazi  c. 1250-1300. The 135 rooms of Betatakin are tucked into a cliffside  alcove 452 ft (138 m) high and 370 ft (113 m) wide. Also situated in a  cliff alcove are the 160 rooms and 6 kivas (ceremonial houses) of Keet  Seel. Inscription House (closed to the public) has 74 rooms.</p><p>Navajo weaving Blankets and rugs made by the Navajo, considered  among the best-made textiles produced by Native Americans of the U.S.  By 1500 the Navajo were well established in what is now the southwest�  ern U.S., where they began to practice weaving when they turned from a  seminomadic life to agriculture. From the Hopi they learned how to make  looms and weave fabrics on a large scale; but whereas the Hopi limited  their designs to striped patterns, the Navajo introduced geometric shapes,  diamonds, lozenges, and zigzags. Traditionally Navajo blankets were  made of natural-coloured wool or wool in dark colours produced by dyes  made from roots, herbs, and minerals. After the introduction of aniline  dyes in the late 19th century, Navajo weavers began using brighter wools  and a broader range of decorative motifs.</p><p>Naval Academy, U.S. See United States Naval Academy</p><p>Naval Limitation, International Conference on See Washing�  ton Conference</p><p>naval warfare Military operations conducted on, under, or over the  sea and waged against other seagoing vessels or targets on land or in the  air. The earliest naval attacks were raids by the armed men of a tribe or  town using fishing boats or merchant ships. The first warships were gal�  leys, replaced in the 16th and 17th centuries by sail-driven warships  equipped with cannons. The British victory over the Spanish Armada  (1588) marked a major development: British galleons refused to allow  the Spanish ships to get close enough for boarding and hand-to-hand  combat and instead pounded them with guns of superior firing capability.  Ships of the line and cruisers emerged in the 17th and 18th centuries. In the  later 19th century, steam replaced sail propulsion, and ironclads offered  greater protection against the increasing power of guns. The battleship,  developed in these years, reigned until World War II, when the Pearl Har�  bor attack proved that bombers launched from aircraft carriers could sink  any and all surface ships. Since then, naval air power� missiles as well as  carrier-based planes�has been the primary weapon of the world�s fleets.  Submarines also play a major role in naval warfare.</p><p>navaratra In Hinduism, a 9-day festival followed on the 10th day by the  dasehra celebration. The festival includes feasting, visiting, public con�  certs, plays, and fairs. Among the goddess Durga�s followers, who are  especially numerous in Bengal and Assam, the Durga-puja is celebrated  during this period; in other parts of India, dasehra is associated with the  victory of Rama over Ravana, acted out in a pageant climaxed by the  burning of effigies of demons.</p><p>Navarino X.na-va-'re-noV, Battle of (Oct. 20, 1827) Naval engage�  ment in the War of Greek Independence against Turkey.

It  encompassed the modern autonomous community of Navarra and part of  the modern French department of Pyrenees-Atlantiques. It was conquered  by the Romans, then the Visigoths, and Charlemagne. It became an inde�  pendent kingdom in the 10th century. A succession of French dynasties  ruled Navarra after 1234. Incorporated into Castile in 1515, it was united  to the French crown when Henry of Navarre became King Henry IV of  France in 1589.</p><p>Navarro \na-'va-ro. Fats orig. Theodore Navarro (b. Sept. 24,  1923, Key West, Fla., U.S.�d. July 7, 1950, New York, N.Y.) U.S. jazz  trumpeter. Navarro replaced Dizzy Gillespie in the big band of Billy Eckstine  in 1946, acquiring a reputation as a virtuoso player capable of executing  complex phrases with rare grace. He participated in the burgeoning jazz  milieu based around 52nd St. in New York City in the late 1940s, work�  ing with bebop innovators such as Bud Powell, Charlie Parker, and Tadd  Dameron (1917-65). Addiction to heroin curtailed his activity, and he died  of tuberculosis.</p><p>Navas de Tolosa, Battle of Las See Battle of Las Navas de Tolosa</p><p>nave Main part of a Christian church, extending from the entrance (the  narthex) to the transept or chancel  (area around the altar). In a basilican  church (see basilica), which has side  aisles, nave refers only to the central  section. Medieval naves were gener�  ally divided into many bays, produc�  ing the effect of great length. During  the Renaissance, the nave format  became more flexible, and the nave  was divided into fewer compart�  ments, giving a feeling of spacious�  ness and balanced proportion among  the height, length, and width, as in  St. Paul's Cathedral.</p><p>navigation Science of directing a  craft by determining its position,  course, and distance traveled. Early  mariners followed landmarks visible  on shore and studied prevailing  winds for clues to direction. The  Phoenicians and Polynesians sailed out of sight of land and used the stars  to set their course. The compass (first used by the Chinese c. 1100) was  the first navigational aid that gave a constant reference point, though its  accuracy was limited, especially in heavy seas. Modem compasses are  stabilized by gyroscopes and housed in binnacles that compensate for the  craft�s motion. Ship speed was first calculated by dropping overboard a  log attached to a reel of line knotted at regular intervals; the number of  knots exposed while the log drifted and a sandglass emptied gave the ves�  sel�s speed in knots (nautical mph). Charts are another essential naviga�  tional tool. Fixing a position requires charts detailing known locations,  together with instruments that calculate a vessel�s bearing relative to them.  The earliest instrument for determining latitude was the quadrant, which  measured the altitude of the polestar or the noonday sun. Other early  instruments included the sextant and the astrolabe. Longitude (used for  navigation with increasing success in the 17th-18th century) was fixed  using chronometers and tables showing positions of celestial bodies  throughout the year. In the 20th century, radio beacons and satellite net�  works allowed aircraft and ships to determine their position. Dead reck�  oning uses an accurate history of a vessel�s headings and speeds drawn  from gyroscopes and from computerized measurements of the craft�s  acceleration. See also Global Positioning System.</p><p>Navigation Acts English laws in the 17th�18th centuries that required  the use of English or colonial ships to carry English trade. The laws were  designed to encourage English shipbuilding and restrict trade competition  from England�s commercial rivals, especially the Dutch. The acts of the  18th century gradually restricted trade by the American colonies and con�  tributed to growing colonial resentment with the imposition of additional  duties on sugar, tobacco, and molasses.</p><p>Navistar International Corp. Leading U.S. truck manufacturer. It  originated as International Harvester Co., which was incorporated in  1902, merging McCormick Harvesting Machine Co. (founded by Cyrus  H.

It began producing tractors  in the 1930s and soon became a major manufacturer of earth-moving  equipment. Facing economic difficulties in the early 1980s, it sold most  of its U.S. construction-equipment business and disposed of its farm-  equipment line to concentrate almost entirely on trucks, and in 1986 the  company changed its name to Navistar International.</p><p>Navratilova \,nav-r3-ti- , lo-v3\ A Martina (b.

In 1982 she won 90 of 93 matches, and in 1983  she won 86 of 87 matches. In 1984 she was honoured for winning the  grand slam but later was denied the title on a technicality. By 1987 she  had won 37 individual grand-slam championships, and by 1994 she had  won 56, ranking second only to Margaret Smith Court. By 1992 she had  accumulated more championships (158) than any other player, male or  female, in tennis history, and she retired in 1994 with 167 titles. In 2000  she returned to professional play, competing in several doubles events. In  2003 she won the mixed doubles at Wimbledon, tying Billie Jean King for  most Wimbledon titles (20). With the victory, Navratilova, who was 46,  became the oldest player to win at Wimbledon.</p><p>navy Warships and craft of every kind maintained by a nation for fight�  ing on, under, or over the sea. A large modem navy includes aircraft car�  riers, cruisers, destroyers, frigates, submarines, minesweepers and minelayers,  gunboats, and various types of support, supply, and repair ships, as well  as naval bases and ports. Naval ships are the chief means by which a  nation extends sea power. Their two chief functions are to achieve sea  control and sea denial. Control of the sea enables a nation and its allies  to carry on maritime commerce, amphibious assaults, and other seaborne  operations that may be essential in wartime. Denial of the sea deprives  enemy merchant vessels and warships of safe navigation. See also U.S.  Navy.</p><p>Naxos Vnak-sas\ Largest island (pop., 1991: 14,838) of the Cyclades,  Greece.

The capital and chief port, Naxos, on the western  coast, is on the site of the island�s ancient and medieval capitals. In ancient  times, it was famous for its wines and the worship of Dionysus. In mythol�  ogy, it is where Theseus abandoned Ariadne. In the 7th-6th centuries bc a  deep-grained white marble was exported for statuary. It was captured by  the Persians in 490 bc and by Athens in 471 bc. A Venetian duchy ruled from  1207 to 1566; it was later ruled by the Turks. In 1830 it joined the Greek  kingdom.

They admired medieval and early  Renaissance painters and rejected most subsequent painting, believing it  abandoned religious ideals in favour of artistic virtuosity. Members lived  and worked together in a semimonastic existence, trying to imitate the  teaching situation of the medieval workshop. The leading members were  Friedrich Overbeck (1789-1869), Franz Pforr (1788-1812), and Peter von  Cornelius (1783-1867).</p><p>Nazareth Hebrew Nazerat \,na-z3-'rat\ Arabic Al-Nasirah</p><p>\en-'na-se-,ra\ Town (pop., 2000 est.: 69,604), northern Israel, southeast  of Haifa. It is Israel�s largest Arab city. In the New Testament, it is the  childhood home of Jesus. It contains many Christian churches and is a  pilgrimage centre. Captured by Christians several times during the Cru�  sades, it was taken by the Ottoman Empire in 1517. It was part of British-  mandate Palestine from 1918 and part of Israel from 1948. Christian Arabs  form the majority of the population.</p><p>Nazi Party German political party of National Socialism. Founded in  1919 as the German Workers� Party, it changed its name to the National  Socialist German Workers� Party when Adolf Hitler became leader (1920-  21). The nickname Nazi was taken from the first word of its full name,  Nationalsozialistische Deutsche Arbeiter-Partei. The party grew from its  home base in Bavaria and attracted members from disaffected elements  throughout Germany. It organized strong-arm groups (later the SA) to  protect its rallies. Though the failed Beer Hall Putsch diminished the par�  ty�s influence, the effects of the Great Depression brought millions of new  members, and in 1932 the party became the largest bloc in the Reichstag.  After Hitler was named chancellor in 1933, he obtained passage of the  Enabling Act, and his government declared the Nazi party to be the only  political party in Germany and required bureaucrats to become members.  The party controlled virtually all activities in Germany until Germany�s  defeat in World War II (1945), after which the party was banned.</p><p>NBA See National Basketball Assn.</p><p>NBC in full National Broadcasting Co. Major U.S. commercial  broadcasting company. It was formed in 1926 by RCA Corp., General  Electric Co. (GE), and Westinghouse and was the first U.S. company to  operate a broadcast network. Directed by RCA�s president David Sarnoff,  it became wholly owned by RCA in 1930. NBC was initially divided into  the semi-independent Blue Network, based on station WJZ, and the Red  Network, based on WEAF, each with links to stations in other cities. By  1938 the Red Network carried 75% of NBC�s programs. The Blue Net�  work was sold in 1941 and became the American Broadcasting Co. (ABC).  NBC entered television broadcasting in a weakened position, and by 1952  it trailed CBS in audience ratings, though it gradually regained its lead�  ing position. In 1986 RCA was sold to GE; in 1987 NBC sold its radio  networks. In the 1990s NBC expanded its cable television programming,  creating MSNBC (an alliance with Microsoft) and CNBC (an alliance  with Dow Jones).</p><p>NCAA See National Collegiate Athletic Assn.</p><p>NCR Corp. U.S. manufacturer of cash registers, computers, and  information-processing systems. It was founded in 1884 as National Cash  Register Co. by John H. Patterson, who bought a failing maker of cash  registers in Dayton, Ohio. He improved the design, sent out an aggres�  sive sales force, and hired repairmen to service his products after sale.  The company expanded in the 20th century, introducing accounting  machines in the 1920s, electronic products during World War II, com�  puter hardware and software in the 1960s, and microelectronics in the  1970s. In 1991 it was purchased by AT&amp;T Corp. and renamed AT&amp;T Glo�  bal Information Solutions. When AT&amp;T split into three companies in  1996, NCR Corp. was spun off and assumed its former name.</p><p>Ndebele \en-d9-'ba-la\ formerly Matabele \,mad-3-'ba-la\ Bantu�  speaking people who live primarily around the city of Bulawayo, Zimb.,  but also in Botswana.

During World War II he initially  served in the Japanese-sponsored army but later helped organize under�  ground resistance to the Japanese. In 1962 he ousted the elected prime  minister U Nu; his subsequent regime combined military dictatorship with  a socialist economic program. Burma became isolated and impoverished  under Ne Win, and he resigned in 1988.

The name derives from the discovery in  1856 of remains in a cave above Germany�s Neander Valley. Some schol�  ars designate the species as Homo neanderthalensis and do not consider  Neanderthals direct ancestors of modern humans {Homo sapiens). Others  regard them as a late archaic form of H. sapiens that was absorbed into  modern human populations in some areas while simply dying out in oth�  ers. Neanderthals were short, stout, and powerful. Cranial capacity  equaled or surpassed that of modem humans, though their braincases were  long, low, and wide. Their limbs were heavy, but they seem to have  walked fully erect and had hands as capable as those of modem humans.  They were cave dwellers who used fire, wielded stone tools and wooden  spears to hunt animals, buried their dead, and cared for their sick or  injured. They may have used language and may have practiced a primi�  tive form of religion.

The near�  death experience varies with each individual, but characteristics fre�  quently include hearing oneself declared dead, feelings of peacefulness,  the sense of leaving one�s body, the sense of moving through a dark tun�  nel toward a bright light, a life review, the crossing of a border, and meet�  ings with other spiritual beings, often deceased friends and relatives. Near�  death experiences are reported by about one-third of those who come close  to death. Cultural and physiological explanations have been offered, but  the causes remain uncertain. Typical aftereffects include greater spiritu�  ality and decreased fear of death.</p><p>Near East See Middle East</p><p>Nebraska State (pop., 2000: 1,711,263), west-central U.S. Bordered  by South Dakota, Iowa, Missouri, Kansas, Colorado, and Wyoming, it  covers 77,353 sq mi (200,343 sq km); its capital is Lincoln.

Indian tribes living in the  area include Pawnee, Oto, and Omaha in the east and centre, as well as  Oglala, Sioux, Arapaho, and Comanche in the west. The U.S. bought the  territory from France as part of the Louisiana Purchase in 1803. In 1804  the Lewis and Clark Expedition visited the Nebraska side of the Missouri  River. It became part of Nebraska Territory with the Kansas-Nebraska Act  of 1854. Nebraska was admitted to the Union as the 37th state in 1867.  Soon after, the population increased, and as Indian resistance on the fron�  tier was broken, settlement extended to Nebraska�s panhandle. At the turn  of the 20th century, it experienced a short but influential Populist move�  ment. In 1937 it established a unicameral legislature, the only one in the  country. Most of the state is agricultural; its industries include food pro�  cessing and machinery. Petroleum is the principal mineral resource.

A proposition is logically necessary if it instantiates a law of logic or can  be made to instantiate a law of logic through substitution of definition-  ally equivalent terms. Examples are �It is raining now or it is not raining  now� and �All men are human beings� (assuming �men� can be replaced  with �male human beings�). Necessary propositions are sometimes said  to be true or false (as the case may be) in all possible worlds. A contin�  gently true or false proposition is thus one that is true in some possible  worlds and false in others (e.g., �France is a democracy�). All true logi�  cally necessary propositions are analytic (see analytic-synthetic distinction)  and knowable A priori. Some philosophers recognize a second category of  �metaphysically� necessary propositions that are not analytic and gener�  ally not a priori; examples include identity statements such as �Water is  H 2 0.�</p><p>Nechako \ni-'cha-ko\ River River, central British Columbia, Canada.

April 9, 1804, Coppet) Swiss-born French financier and  director-general of finance under Louis XVI. He became a banker in Paris,  and, after becoming wealthy from speculating during the Seven Years�  War, he was appointed minister of Geneva in Paris (1768). He retired from  banking in 1772 and became France�s director-general of finance in 1777.  Despite his cautious reforms, he was forced to resign in 1781 over oppo�  sition to his scheme to help finance the American Revolution. He was  recalled in 1788 to rescue the almost bankrupt France, and he proposed  financial and political reforms that included a limited constitutional mon�  archy. Opposition from the royal court led to Necker�s dismissal on July  11, 1789, an event that provoked the storming of the Bastille. After serv�  ing again briefly (1789-90), he retired to Geneva. Germaine de Stael was  his daughter.</p><p>necropolis \ni-'kra-p3-bs\ (Greek: �city of the dead�) Extensive and  elaborate burial place serving an ancient city.

He was a Roman  Catholic priest, whose reading about  microscopic organisms led him to  study natural history in London and  Paris (1746-49). He became a strong  supporter of the theory that life arose  from inorganic matter (spontaneous generation) and that life processes  cannot be explained by the laws of chemistry and physics (vitalism). In  1750 he presented his theory of spontaneous generation and attempted to  offer scientific evidence supporting it.</p><p>needle Basic implement used in sewing or embroidering and, in vari�  ant forms, for knitting and crocheting. The sewing needle is small, slen�  der, and rodlike. One end is sharply pointed to make passing it through  fabric easy; the other end has a slot (called an eye) to carry a thread. Mod�  ern sewing needles are made of steel. Crocheting needles are eyeless and  have a hook on one end; they are usually of steel or plastic. Knitting  needles are long, made of various materials, and bluntly pointed at one  or both ends, sometimes with a knob at the end opposite the point.</p><p>needlefish Any of about 60 species (family Belonidae) of primarily  marine, edible, carnivorous fishes found throughout temperate and tropi�  cal waters.

It may  render one civilly and sometimes criminally liable for resulting injuries.  The doctrine of negligence does not require the elimination of all risk, but  rather only foreseeable and unreasonable risk.

It began among French-speaking African and Caribbean writers liv�  ing in Paris as a protest against French colonial rule and the policy of  assimilation. Its leading figures� Leopold Senghor of Senegal, Aime Cesaire  of Martinique, and Leon Damas (1912-78) of French Guiana�began to  examine Western values critically and to reassess African culture. The  group believed that the value and dignity of African traditions and peoples  must be asserted, that Africans must look to their own heritage for val�  ues and traditions, and that writers should use African subject matter and  poetic traditions. The movement faded in the early 1960s after its objec�  tives had been achieved in most African countries.</p><p>Negro leagues Associations of teams of black baseball players active  largely between 1920 and the late 1940s.

The most noted teams  included the Homestead (Pa.) Grays, who won nine pennants in the years  1937�45 and included the great hitters Cool Papa Bell, Buck Leonard, and  Josh Gibson. In the mid 1930s the Pittsburgh Crawfords included Satchel</p><p>Paige and the clutch-hitter William Julius �Judy� Johnson.

His story is told in the biblical book of  Nehemiah. He was cupbearer to the Persian ruler Artaxerxes I soon after  the end of the Babylonian Exile, when the Temple of Jerusalem had been  rebuilt but the Jewish community was still weak and fragmented. Around  444 bc he was put in charge of Jerusalem�s reconstruction, and he orga�  nized the rebuilding of the city walls. He also revived adherence to Mosaic  law and forbade intermarriage with non-Jews. His work as a reformer was  later continued by Ezra.</p><p>Nehru \'na-ru\, Jawaharlal (b. Nov. 14, 1889, Allahabad, India�d.  May 27, 1964, New Delhi) First  prime minister of independent India  (1947-64). Son of the independence  advocate Motilal Nehru (1861�</p><p>1931), Nehru was educated at home  and in Britain and became a lawyer in  1912. More interested in politics than  law, he was impressed by Mohandas  K. Gandhi�s approach to Indian inde�  pendence. His close association with  the Indian National Congress began  in 1919; in 1929 he became its presi�  dent, presiding over the historic  Lahore session that proclaimed com�  plete independence (rather than  dominion status) as India�s political  goal. He was imprisoned nine times  between 1921 and 1945 for his politi�  cal activity. When India was granted  limited self-government in 1935, the  Congress Party under Nehru refused  to form coalition governments with  the Muslim League in some provinces; the hardening of relations between  Hindus and Muslims that followed ultimately led to the partition of India  and the creation of Pakistan. Shortly before Gandhi�s assassination in  1948, Nehru became the first prime minister of independent India. He  attempted a foreign policy of nonalignment during the Cold War, drawing  harsh criticism if he appeared to favour either camp. During his tenure,  India clashed with Pakistan over the Kashmir region and with China over  the Brahmaputra River valley. He wrested Goa from the Portuguese.  Domestically, he promoted democracy, socialism, secularism, and unity,  adapting modern values to Indian conditions. His daughter, Indira Gandhi,  became prime minister two years after his death.</p><p>Nei Monggol See Inner Mongolia</p><p>Nefertiti, painted limestone bust, about  1350 bc; in the Egyptian Museum, Ber-</p><p>BILDARCHIV PREUSSISCHER KULTURBESITZ, AGYPTISCHES  MUSEUM, STAATUCHE MUSEEN ZU BERUN-PREUSSISCHER  KULTURBESITZ, BERLIN; PHOTOGRAPH, JURGEN LIEPE</p><p>Jawaharlal Nehru, photograph by  Yousuf Karsh, 1956.</p><p>� KARSH-RAPHO/PHOTO RESEARCHERS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Neilson &#x25BA; nene I 1341</p><p>Neilson Vnel-ssnV James Beaumont (b.

He  won the U.S. Open (1939), the Masters (1937, 1942), and the PGA cham�  pionship (1940, 1945), setting records in 1945 when he won 18 out of 30  tournaments, 11 in succession.</p><p>Nelson, Horatio Nelson, Viscount known as Lord Nelson (b.</p><p>Sept. 29, 1758, Burnham Thorpe, Norfolk, Eng.�d. Oct. 21, 1805, at sea,  off Cape Trafalgar, Spain) British naval commander. He entered the navy  in 1770 and served in the West Indies from 1777 to 1783. In 1793 he was  sent to support the British allies against the French in the Mediterranean.  After the British victory against the Spanish and French in the Battle of  Cape St. Vincent (1797), he was promoted to rear admiral. In 1798 he  pursued Napoleon�s fleet to Egypt, where he won the decisive Battle of  the Nile. During a prolonged stay in Naples for his ships� repairs, he pur�  sued a love affair with Emma, Lady Hamilton. For helping restore the  Neapolitan king Ferdinand I to power (1799), he was created duke di  Bronte. As second in command of an expedition to attack Denmark, he  skillfully won the Battle of Copenhagen (1801) and was appointed com�  mander in chief of the navy. In 1805 he was sent to the Mediterranean to  meet the threat posed by the French fleet in Napoleon�s scheme to invade  England. In the ensuing Battle of Trafalgar, Nelson, aboard his flagship  Victory, was shot by a French sniper from the Redoutable and died just  as the British fleet secured its victory. His death was widely mourned, and  he became England�s most popular hero. His brilliant tactical command  assured British naval supremacy for over 100 years.</p><p>Nelson, Willie (b. April 30, 1933, Fort Worth, Texas, U.S.) U.S. coun�  try music singer and songwriter. His grandfather taught him to play gui�  tar, and by age 10 he was performing at local dances. After working as a  disc jockey, in 1961 he moved to Nashville, Tenn., where he wrote hit  songs for dozens of country, rhythm-and-blues, and pop singers; these  songs include �Hello Walls,� �Night Life,� and �Crazy.� Returning to  Texas, he released the hit album Red Headed Stranger (1975); it was fol�  lowed by Wanted: The Outlaws, which outsold every country album that  had preceded it, and Stardust (1978), with songs by Hoagy Carmichael and  Irving Berlin. He has recorded with at least 75 other singers, including  Waylon Jennings (b. 1937). In the 1980s he organized annual Farm Aid  festivals to raise money for farmers. His later albums include the criti�  cally acclaimed Teatro (1998).</p><p>Nelson River River, north-central Manitoba, Canada. Flowing out of  northern Lake Winnipeg into Hudson Bay, it is 400 mi (644 km) long. It  was discovered in 1612 by the English explorer Thomas Button, and a  trading post of the Hudson's Bay Company was established there c. 1670.  Fur traders used the river as an inland route.

He  attended Harvard University and served as a pilot in World War II before  teaching at various colleges, including Bennington. His verse, marked by  irony and self-deprecatory wit, is often about nature; it appeal�s in several  volumes beginning with The Image and the Law (1947) and including  Collected Poems (1977, Pulitzer Prize, National Book Award). His fiction  includes The Homecoming Game (1957) and A Commodity of Dreams and  Other Stories (1960). He was poet laureate of the U.S. (1988-90). His  sister Diane Arbus was a notable photographer.</p><p>Nemesis Vne-mo-sosN Greek goddess of retribution. In the earliest  Greek religion she was worshiped as a fertility goddess. Later legends  told how Zeus, in the form of a swan, coupled with her in the form of a  goose. Nemesis then laid the egg from which Helen of Troy was born (in  other versions Leda was said to be Helen�s mother). Nemesis dealt out  punishments that expressed the gods� disapproval of human presumption.  Her cult was also popular in Rome, particularly among soldiers.</p><p>Nemi Vna-me\, Lake ancient Lacus Nemorensis Crater lake in the  Alban Hills, southeast of Rome, Italy.

After criticizing the Fas�  cist Party and Benito Mussolini, he was arrested and fled to Paris (1926). In  the Spanish Civil War, he cofounded the Garibaldi Brigade. He was impris�  oned in Germany and Italy in World War II, then became leader of the PSI;  he led the left wing in alliance with the Communist Party until 1956. In  1963 he allied the PSI with the Christian Democrats and served as vice pre�  mier in three successive cabinets and as foreign minister (1968-69).</p><p>Neo-Confucianism In China, a rationalistic revival of Confucianism  in the 11th century that influenced Chinese thought for 800 years. The  movement sought to reestablish the supremacy of the Confucian heritage  over the increasingly popular Buddhism and Daoism. Its two principal  schools of thought were the Lixue (School of Principle), whose chief phi�  losopher was Zhu Xi, and the Xinxue (School of Mind), represented by Lu  Xiangshan and Wang Yangming. Neo-Confucianism was introduced into  Japan by Zen Buddhists and became the guiding philosophy of the  Tokugawa period (1603-1867), providing a heavenly sanction for the exist�  ing social order. Its emphasis on classical literature led to renewed inter�  est in the Japanese classics and a revival of Shinto studies.</p><p>neo-Darwinism Theory of evolution that represents a synthesis of  Charles Darwin�s theory in terms of natural selection and modern popu�  lation genetics. The term was first used after 1896 to describe the theo�  ries of August Weismann (1834-1914), who asserted that his germ-plasm  theory made impossible the inheritance of acquired characteristics and  supported natural selection as the only major process that would account  for biological evolution.</p><p>Neo-Expressionism Art movement, chiefly of painters, that domi�  nated the European and American art market in the early to mid-1980s.  It was controversial both in the quality of its production and in the highly  commercialized aspects of its presentation. Its practitioners, including  Julian Schnabel and Anselm Kiefer, reacted to the highly intellectualized  abstract art of the 1970s by creating dramatic, gestural paintings that  incorporated some figurative elements and recognizable symbols. Their  art was characterized by a tense yet playful presentation of objects in a  �primitivist� manner, vivid colour harmonies, large scale, and a sense of  inner tension and alienation. See also Expressionism.</p><p>Neo-Impressionism Movement in French painting of the late 19th  century, in reaction against the realism of Impressionism. The Neo-  Impressionists, led by Georges Seurat and Paul Signac, applied paint to  canvas in dots of contrasting pigments, scientifically chosen so that adja�  cent dots would blend from a distance into a single colour. The technique  is known as pointillism. Whereas the Impressionists captured the fugitive  effects of colour and light, the Neo-Impressionists crystallized them into  immobile monumentality.</p><p>Neo-Kantianism Revival of Kantianism in German universities that  began c. 1860. At first primarily an epistemological movement, Neo-  Kantianism slowly extended over the whole domain of philosophy. The  first decisive impetus toward reviving Immanuel Kant�s ideas came from  natural scientists. Hermann von Helmholtz applied physiological studies of  the senses to the question of the epistemological significance of spatial  perception raised by The Critique of Pure Reason (1781). Neo-Kantianism  reached its apex in the early 20th-century Marburg school, which included  Hermann Cohen (1842-1918) and Paul Natorp (1854-1924). They repu�  diated Helmholtz�s naturalism and reaffirmed the importance of the tran�  scendental method. Ernst Cassirer, another Marburg-school figure, brought  Kantian principles to bear on the whole realm of cultural phenomena.  Wilhelm Windelband (1848-1915) and Heinrich Rickert (1863-1936)  introduced Kantianism into the philosophy of history. Neo-Kantianism  also influenced the phenomenology of Edmund Husserl and of the early  works of Martin Heidegger.</p><p>Neo-Paganism Any of several movements that attempt to revive the  polytheistic religions of Europe and the Middle East. Largely a product</p><p>of the 1960s, contemporary Neo-Paganism has flourished particularly in  the U.S., Britain, and Scandinavia. Its adherents often have deep ecologi�  cal concerns and an attachment to nature; many worship an earth-mother  goddess and center their rituals on the change of the seasons. Since the  late 1970s, Neo-Paganism has also attracted feminists open to female per�  sonifications of the deity. Major Neo-Pagan groups include the Church of  All Worlds, Feraferia, Pagan Way, the Reformed Druids of North America,  the Church of the Eternal Source, and the Viking Brotherhood. See also  Wicca.</p><p>Neo-Thomism X.ne-o-'ta-.mi-zonA Modern revival of the philosophi�  cal and theological system developed by St. Thomas Aquinas and his later  commentators. Neo-Thomism follows Aquinas in distinguishing between  the realms of nature (in which reason and philosophy hold sway) and  supemature (in which faith and theology are dominant). Aquinas�s  thought was presented in philosophy and theology courses or manuals,  especially in the Dominican Order, through the 17th and 18th centuries,  though most manuals of this period were watered with the opinions of  other Schoolmen and remained remote from modern concerns. The mod�  ern revival of authentic Thomism began in the 19th century under the  influence of the Jesuits and the papacy, who sought a sound philosophi�  cal foundation on which to develop responses to contemporary intellec�  tual and social problems. After the mid-20th century neo-Thomists  attempted to develop an adequate philosophy of science, to take into  account the findings of phenomenology and psychiatry, and to evaluate the  ontologies of existentialism and naturalism.

The movement concerned itself with  the logic of entire Classical volumes, unlike Classical revivalism (see  Greek Revival), which tended to reuse Classical parts. Neoclassical archi�  tecture is characterized by grandeur of scale; simplicity of geometric  forms; Greek, especially Doric (see order), or Roman detail; dramatic use  of columns; and a preference for blank walls. The new taste for antique  simplicity represented a general reaction to the excesses of the Rococo  style. Neoclassicism thrived in the U.S. and Europe, with examples occur�  ring in almost every major city. Russia�s Catherine II transformed St.  Petersburg into an unparalleled collection of Neoclassical buildings as  advanced as any contemporary French and English work. By 1800 nearly  all new British architecture reflected the Neoclassical spirit (see Robert  Adam; John Soane). France�s boldest innovator was Claude-Nicolas  Ledoux, who had a central role in the evolution of Neoclassical architec�  ture. In the U.S. Neoclassicism continued to flourish throughout the 19th  century, as many architects looked to make the analogy between the young  country and imperial Rome when designing major government buildings.  The style also spread to colonial Latin America.</p><p>Neoclassicism See Classicism and Neoclassicism</p><p>neoconservatism U.S. political movement. It originated in the 1960s  among conservatives and some liberals who were repelled by or disillu�  sioned with what they viewed as the political and cultural trends of the  time, including leftist political radicalism, lack of respect for authority  and tradition, and hedonistic and immoral lifestyles. Neoconservatives  generally advocate a free-market economy with minimum taxation and  government economic regulation; strict limits on government-provided  social-welfare programs; and a strong military supported by large defense  budgets. Neoconservatives also believe that government policy should  respect the importance of traditional institutions such as religion and the  family. Unlike most conservatives of earlier generations, neoconserva�  tives maintain that the United States should take an active role in world  affairs, though they are generally suspicious of international institutions,  such as the United Nations and the World Court, whose authority could  intrude upon American sovereignty or limit the country�s freedom to act  in its own interests.

It is a component of important alloys, among them misch  metal (15% neodymium), used in lighter flints and various metallurgical  processes. Alloyed with iron and boron, neodymium is the basis for pow�  erful permanent magnets used in computer hard drives, lightweight ear�  phones, and numerous other applications. Neodymium compounds are  employed as ceramics glazes. The crude oxide counteracts the greenish  cast imparted to glass by iron contaminants, and a very pure oxide is used  to make a vivid purple glass.

Like earlier fascist movements,  neofascism advocated extreme nationalism, opposed liberal individual�  ism, attacked Marxist and other left-wing ideologies, indulged in racist  and xenophobic scapegoating, and promoted populist right-wing eco�  nomic programs. Unlike the fascists, however, neofascists placed more  blame for their countries� problems on non-European immigrants than on  leftists and Jews, displayed little interest in taking lebensraum (German:  �living space�) through the military conquest of other states, and made  concerted efforts to portray themselves as democratic and �mainstream.�  The National Front in France, led by Jean-Marie Le Pen, and the Liberal-  Democratic Party in Russia, led by Vladimir Zhirinovsky, are often cited  as neofascist.</p><p>Neolithic \,ne-9-'li-thik\ Period or New Stone Age Final stage of  technological development or cultural evolution among prehistoric  humans. It is characterized by the use of stone tools shaped by polishing  or grinding, the domestication of plants or animals, the establishment of  permanent villages, and the practice of such crafts as pottery and weav�  ing. The Neolithic followed the Paleolithic Period (and in northwestern  Europe the Mesolithic) and preceded the Bronze Age. Its beginning is  associated with the villages that emerged in South Asia c. 9000 bc and  flourished in the Tigris and Euphrates river valleys from c. 7000 bc. Farm�  ing spread northward throughout Eurasia, reaching Britain and Scandi�  navia only after 3000 bc. Neolithic technologies also spread to the Indus  River valley of India by 5000 bc and to the Huang Ho valley of China  by c. 3500 bc. The term is not applied to the New World, though Neolithic  modes of life were achieved independently there by c. 2500 bc.</p><p>neon Chemical element, chemical symbol Ne, atomic number 10. One of  the noble GASes, neon is colourless, odourless, tasteless, and completely  unreactive. It occurs in minute amounts in the atmosphere and is obtained  by fractional distillation of liquefied air. When under low pressure, it glows  a bright orange-red if an electric current is passed through it. It was dis�  covered in 1898, and since the 1920s its chief use has been in luminous  tubes and bulbs.</p><p>neoplasm See tumor</p><p>Neoplatonism Form of Platonism developed by Plotinus in the 3rd  century ad and modified by his successors. It came to dominate the Greek  philosophical schools and remained predominant until the teaching of  philosophy by pagans ended in the late 6th century. It postulated an all-  sufficient unity, the One, from which emanated the Divine Mind, or LOGOS,  and below that, the World Soul. Those transcendent realities were thought  to support the visible world. All things emanated from the One, and indi�  vidual souls could rise to mystical union with the One through contem�  plation. Though Plotinus�s thought in some respects resembles Gnosticism,  he was passionately opposed to that doctrine.</p><p>neoprene \'ne-3-,pren\ Any of a class of elastomers (rubberlike syn�  thetic organic compounds of high molecular weight) made by polymeriza�  tion of the monomer 2-chloro-1,3-butadiene and vulcanized (cross-linked,  like rubber), by sulfur, metallic oxides, or other agents. These synthetic  rubbers, discovered in 1931 (see W.H. Carothers), are generally too  expensive to use in making tires, but their resistance to chemicals and  oxidation (see oxidation-reduction) makes them valuable in specialized  applications, including shoe soles, hoses, adhesives, gaskets, seals, and  foamed articles.</p><p>Neorealism or neorealismo Italian aesthetic movement that flour�  ished especially after World War II. It sought to deal realistically with the  events leading up to the war and with their resulting social problems.  Rooted in the 1920s, it was similar to the verismo (�realism�) movement,  from which it originated, but differed in that its upsurge resulted from the  intense feelings inspired by fascist repression, the Resistance, and the war.  Neorealist writers include Italo Calvino, Alberto Moravia, and Cesare  Pavese. During the fascist years many Neorealist writers went into hiding,  were imprisoned or exiled, or joined the Resistance. The movement  reemerged in full strength after the war. Neorealism in film embraced a  documentary-like objectivity; actors were often amatuers, and the action  centred on commonplace situations. Often crudely and hastily made, Neo�  realist productions stood in stark contrast to traditional escapist feature</p><p>films. Two notable examples of Neorealist films are Roberto Rossellini�s  Open City (1945) and Vittorio De Sica�s The Bicycle Thief { 1948).</p><p>Neosho \ne-'o-sho\ River or Grand River River, southeastern Kan�  sas and northeastern Oklahoma, U.S. It rises in east-central Kansas and  flows into Oklahoma, where it is also known as the Grand, to join the  Arkansas River near Fort Gibson.

Languages:</p><p>Nepali (official), English, various others.</p><p>Religions: Hinduism (official); also Bud�  dhism, Islam. Currency: Nepalese rupee.</p><p>Nepal contains some of the most rugged mountainous terrain in the world.  The Great Himalayas, including Mount Everest, are in its central and north�  ern parts. As a result of its years of geographic and self-imposed isola�  tion, it is one of the world�s least-developed countries. Its market economy  is mostly based on agriculture, including livestock raising; tourism is also  important. Nepal is a constitutional monarchy with a bicameral parlia�  ment; its chief of state is the king, and the head of government is the  prime minister. The region developed under early Buddhist influence, and  dynastic rule dates from about the 4th century ad. It was formed into a  single kingdom in 1769 and fought border wars with China, Tibet, and  British India in the 18th�19th centuries. Its independence was recognized  by Britain in 1923. A new constitution in 1990 restricted royal authority  and accepted a democratically elected parliamentary government. Nepal  signed trade agreements with India in 1997. The country was stunned in  2001 when the crown prince killed most members of the royal family,  including himself.</p><p>nepheline \'ne-f3-,len\ or nephelite Most common feldspathoid min�  eral, an aluminosilicate of sodium and potassium (Na 3 KAl 4 Si 4 0 16 ).

There are numerous  kinds, involving different kidney tissues. The most common type is Bright  disease. Symptoms vary with the type of nephritis; severe cases can result  in kidney failure. Causes include infection, allergy or autoimmune disease,  blockage in the urinary system, and hereditary diseases. Treatment  addresses the cause where possible.</p><p>nephrology \ni-'fra-b-je\ Branch of medicine dealing with kidney func�  tion and diseases. An understanding of kidney physiology is important  not only in treating kidney disease but in knowing the effect of drugs,  diet, and hypertension on kidney disease, and vice versa. The first scien�  tific observations of the kidney were made in the mid-17th century by  Lorenzo Bellini (1643-1704) and Marcello Malpighi; Carl Ludwig was the  first to elaborate on their true physiological function (1844). A key devel�  opment in nephrology was the permanent arteriovenous shunt (1960),  which made repeated hemodialysis feasible, instantly changing the out�  look for chronic-renal-disease patients from certain death to 90% survival.  See also dialysis, kidney failure, kidney stone, kidney transplant, nephron.</p><p>nephron Functional unit of the kidney that removes waste and excess  substances from the blood to produce urine. Each of the million or so  nephrons in each kidney is a tubule 1.2-2.2 in. (30-55 mm) long. At one  end it is closed, expanded, and folded into a double-walled cuplike struc�  ture (Bowman�s capsule) enclosing a cluster of capillaries (glomerulus).  Fluid forced out of the blood through the capillary walls of the glomer�  ulus into Bowman�s capsule flows into the adjacent renal tubule, where  water and nutrients are selectively reabsorbed from the fluid back into the  blood, and electrolytes such as sodium and potassium are balanced in sev�  eral distinct sections along its length. The final concentrated product is  urine. See also urinary system.</p><p>Neptune Eighth planet from the Sun, discovered in 1846 and named for  the Roman god of the sea. It has an average distance from the Sun of 2.8  billion mi (4.5 billion km), taking nearly 164 years to complete one orbit  and rotating every 16.11 hours. Neptune has more than 17 times Earth�s  mass, 58 times its volume, and 12% stronger gravity at the top of its  atmosphere. It has an equatorial diameter of 30,775 mi (49,528 km). Nep�  tune consists largely of hydrogen and helium. It has no solid surface; its  interior is believed to consist of a fluid mixture of rock, ices, and gas. Its  atmosphere contains substantial amounts of methane gas, whose absorp�  tion of red light causes Neptune�s  deep blue-green colour. The Voyager  2 space probe in 1989 discovered  winds of over 1,570 mi/hour (700  m/second), the fastest known for any  of the Sun�s planets, and dark spots  that appear to be storms similar to  Jupiter�s Great Red Spot. Neptune  receives little solar radiation, but it  radiates substantially more energy  than it receives, which indicates an  internal heat source. Neptune�s weak  magnetic field traps charged par�  ticles in a belt around the planet.</p><p>Neptune has a system of rings, made  up largely of dust-size particles, and  at least 13 moons; the largest is Tri�  ton, almost as big as Earth�s Moon.</p><p>Neptune In Roman religion, the god  of water. Neptune was originally the  god of fresh water, but by 399 bc he  was identified with the Greek god  Poseidon and thus became a deity of  the sea. His female counterpart, Sala-  cia, probably began as a goddess of  spring water but was later equated  with the Greek goddess Amphitrite.</p><p>Neptune�s festival (Neptunalia) took  place in the heat of summer (July 23),</p><p>when fresh water was scarcest.

In the 1st millennium bc he  was described as a benefactor who  hears prayers, restores the dead to  life, and protects agriculture and flocks. Later he was called a �destroy�  ing flame� and was depicted as a god of pestilence, hunger, and devas�  tation. The other sphere of Nergal�s power was the underworld, where he  ruled as king and where the goddess Ereshkigal was his queen.</p><p>Neri \'na-re. Saint Philip (b. July 21, 1515, Florence�d.

In 1548 he  cofounded a society of laymen dedicated to the care of pilgrims, the poor,  and the sick. After his ordination in 1551 he moved to the community of  San Girolamo della Carita in Rome. From 1564 to 1575 he was rector of  the church of San Giovanni, and in 1575 Gregory XIII granted him Santa  Maria in Vallicella, where he established his Congregation of the Oratory,  a group of priests and clerics engaged in devotion and charitable activi�  ties. One of the outstanding mystics of the Counter-Reformation, he was  noted for his eloquence as a preacher.</p><p>Nernst Vnemst\, Walther Hermann (b. June 25, 1864, Briesen,  Prussia�d. Nov. 18, 1941, Muskau, Ger.) German scientist, one of the  founders of modern physical chemistry. He taught at the Universities of  Gottingen and Berlin until forced to retire in 1933 by the Nazi regime.  Nernst�s researches on the theory of electric cells (see battery), the ther�  modynamics of chemical equilibrium, the properties of vapours at high  temperatures and of solids at low temperatures, and the mechanism of  photochemistry have had important applications. His formulation of the  third law of thermodynamics gained him a 1920 Nobel Prize. He also  invented an improved electric light and an electronically amplified piano.</p><p>Nero in full Nero Claudius Caesar Augustus (or Drusus)  Germanicus orig. Lucius Domitius Ahenobarbus (b.

He was adopted by Claudius when the emperor married Nero�s mother,  Agrippina the Younger, and took the throne after Claudius died. He was  guided by his tutor, Seneca, and by Agrippina until he murdered her and  broke free of his advisers. By respecting the Senate and leaving imperial  administration alone, he became popular in the east, but Boudicca�s revolt  in Britain (61), unemployment, and contempt for his frivolousness and  excesses caused dissatisfaction.

He began  writing poetry at age 10, and at 20  he published his most widely read  work, Twenty Love Poems and a  Song of Despair (1924), inspired by  an unhappy love affair. In 1927 he  was named an honorary consul, and  he later represented Chile in several  Asian and Latin American countries;  late in life he was ambassador to  France. While in Asia he began Resi�  dence on Earth (1933, 1935, 1947),  a verse cycle remarkable for its  examination of social decay and per�  sonal isolation. In 1945 he was  elected senator and joined the Com�  munist Party; he later spent years in  exile when the government turned  toward the right. Canto General  (1950), his great epic poem about the  American continents, was deeply  influenced by Walt Whitman and is  the culminating expression of his political beliefs. Elemental Odes (1954)  celebrates common, everyday objects. He was awarded the Nobel Prize  for Literature in 1971.</p><p>Nerva Vnor-voV in full Nerva Caesar Augustus orig.

After an undistinguished  career, he was chosen to succeed Domitian because of his age, dignity, and  lack of children who would succeed him. He rejected Domitian�s autocratic  tyranny but completed Domitian�s building projects and instituted his  administrative and financial reforms. He adopted Trajan as his heir.</p><p>nerve See neuron</p><p>nerve gas Weapon of chemical warfare that affects the transmission of  nerve impulses through the nervous system. The organophosphorus nerve  agents Tabun, Sarin, and Soman were developed by Germany during  World War II but not used. They and a newer agent, VX, were produced  in huge quantities by the U.S. and Soviet Union during the Cold War;  their stockpiling and use during war are now banned by the Chemical  Weapons Convention of 1993. A single droplet of VX or Sarin, if inhaled  or in contact with the skin, can be absorbed into the bloodstream and  paralyze the nervous system, leading to respiratory failure and immedi�  ate death. Sarin was used in 1995 in a lethal attack in the Tokyo subways  by members of AUM Shinrikyo.</p><p>Nervi Vner-ve\, Pier Luigi (b. June 21, 1891, Sondrio, Italy�d. Jan.  9, 1979, Rome) Italian engineer and building contractor. He became inter�  nationally renowned for his invention of ferro-cement, a material of his  own invention composed of dense concrete heavily reinforced with evenly  distributed steel mesh that together give it both lightness and strength.  His first significant projects included a series of airplane hangars in Italy  (1935-41) conceived as concrete vaults with huge spans. In addition to  designing buildings, he succeeded in building a sailboat with a ferro-  cement hull only 0.5 in. (1.25 cm) thick. Ferro-cement was vital to his  complex for the Turin Exhibition (1949-50), a prefabricated, corrugated  cylindrical 309-ft (93-m) arch. Nervi worked on the UNESCO headquar�  ters in Paris (1950) with Marcel Breuer and helped design Italy�s first sky�  scraper, the Pirelli Building in Milan (1955-59). Although Nervi�s  primary concern was never aesthetic, many of his works nonetheless  achieved remarkable expressive force.</p><p>nervous system System of specialized cells (neurons, or nerve cells)  that conduct stimuli from a sensory receptor through a neuron network  to the site (e.g., a gland or muscle) where the response occurs. In humans,  it consists of the central and peripheral nervous systems, the former con�  sisting of the brain and spinal cord and the latter of the nerves, which carry  impulses to and from the central nervous system. The cranial nerves  handle head and neck sensory and motor activities, except the vagus  nerve, which conducts signals to visceral organs. Each spinal nerve is  attached to the spinal cord by a sensory and a motor root. These exit  between the vertebrae and merge to form a large mixed nerve, which  branches to supply a defined area of the body. Disorders include amyo�  trophic LATERAL SCLEROSIS, CHOREA, EPILEPSY, MYASTHENIA GRAVIS, NEURAL TUBE DEFECT,  parkinsonism, and poliomyelitis. Effects of disorders range from transient tics  and minor personality changes to major personality disruptions, seizures,  paralysis, and death.</p><p>Nesiotes See Critius and Nesiotes</p><p>Ness, Eliot (b.

He was 26 years old when he was hired  as a special agent of the U.S. Department of Justice to head its Chicago  Prohibition bureau, with the express purpose of breaking up the bootleg�  ging network of Al Capone. He formed a nine-man team of extremely  dedicated and unbribable officers, �the Untouchables�; the evidence they  collected helped send Capone to prison for income-tax evasion in 1931.  After Prohibition was ended in 1933, Ness headed the alcohol-tax unit of  the U.S. Treasury department (1933-35); he was later director of public  safety in Cleveland (1935�41) and director of a division of the Federal  Security Agency (1941-45).</p><p>Ness, Loch Lake, Highland council area, Scotland.

Headquar�  tered in Vevey, Switz., it operates  branches and subsidiaries in more  than 70 countries. Its products  include condensed and powdered milk, baby foods, chocolate, cheese,  instant coffee and tea, condiments, and frozen foods. Its history dates to  1866, when two Swiss firms were established, the Anglo-Swiss Con�  densed Milk Co. and a company founded by Henri Nestle to manufacture  the first infant formula. In 1905 they merged to become the Nestle and  Anglo-Swiss Condensed Milk Co. Nestle created the first milk chocolate  and in 1937 the first instant coffee, which it produced under the name  Nescafe. It acquired various other firms, including Crosse &amp; Blackwell  in 1960, Stouffer Corp. in 1973, Carnation Co. in 1984, and Ralston Purina  pet foods in 2001. Acquisitions have helped the company maintain its  ranking as the world�s largest food company. Nestle adopted its present  name in 1977.</p><p>Nestor In Greek legend, the king of Pylos in Eus. All his brothers were  killed by Heracles, but Nestor survived. In Homer�s Iliad he appeared as  an elder statesman who entertained the warriors with tales of his youth�  ful exploits.

As bishop of Constantinople from 428, he aroused controversy when he  objected to Cyril of Alexandria�s granting Mary the title of Theotokos  (�God-Bearer�), which he believed compromised Christ�s full humanity.  In 431 the Council of Ephesus condemned his teaching as heresy on the  ground that he denied the reality of Christ�s incarnation, and Nestorius  went into exile, first in the Libyan desert and then in Upper Egypt.

The Netherlands� southern  and eastern region consists mostly of plains and a few high ridges; its  western and northern region is lower and includes polders on the site of  the Zuiderzee and the common delta of the Rhine, Meuse, and Schelde riv�  ers. Coastal areas are almost completely below sea level and are protected  by dunes and artificial dikes. Although densely populated, the country has  a low birthrate. Its developed market economy is based largely on finan�  cial services, light and heavy industries, and trade. It is a constitutional  monarchy with a parliament comprising two legislative houses; its chief  of state is the monarch, and the head of government is the prime minis�  ter. Celtic and Germanic tribes inhabited the region at the time of the  Roman conquest. Under the Romans trade and industry flourished, but by  the mid-3rd century ad Roman power had waned, eroded by resurgent  Germanic tribes and the encroachment of the sea. A Germanic invasion  (406^107) ended Roman control. The Merovingian dynasty followed the  Romans but was supplanted in the 7th century by the Carolingian dynasty,  which converted the area to Christianity. After Charlemagne�s death in  814, the area was increasingly the target of Viking attacks. It became part  of the medieval kingdom of Lotharingia (see Lorraine), which avoided  incorporation into the Holy Roman Empire by investing its bishops and  abbots with secular powers, leading to the establishment of an Imperial  Church. Beginning in the 12th century, much land was reclaimed from  the sea as dike building occurred on a large scale; Flanders developed as  a textiles centre. The dukes of Burgundy gained control in the late 14th  century. By the early 16th century the Low Countries came to be ruled  by the Spanish Habsburgs. The Dutch had taken the lead in fishing and  shipbuilding, which laid the foundation for Holland�s remarkable 17th-  century prosperity. Culturally, this was the period of Jan van Eyck, Tho�  mas a Kempis, and Desiderius Erasmus. Calvinism and Anabaptist doctrines  attracted many followers. In 1581 the seven northern provinces, led by  Calvinists, declared their independence from Spain, and in 1648, follow�  ing the Thirty Years' War, Spain recognized Dutch independence. The 17th  century was the golden age of Dutch civilization. Benedict de Spinoza and  Rene Descartes enjoyed the intellectual freedom, and Rembrandt and  Johannes Vermeer painted their masterpieces.

The Netherlands remained neu�  tral in World War I and declared neutrality in World War II but was  occupied by Germany. After the war it lost the Netherlands Indies (Indo�  nesia from 1949) and Netherlands New Guinea (in 1962; now Irian Jaya).  It joined NATO in 1949 and was a founding member of the European Eco�  nomic Community (later renamed the European Community and now  embedded in the European Union).

Area: 308 sq mi (800 sq km). It  consists of two widely separated groups of islands: Sint Eustatius, the  southern section of St. Martin, and Saba making up the northern group,  at the northern end of the Leeward Islands; and Curacao and Bonaire (and  also Aruba until 1986) constituting the southern group, about 500 mi (800  km) to the southwest, off the coast of Venezuela. The capital, on Curasao,  is Willemstad. Originally inhabited by Arawak and Carib Indians, the  islands were encountered in the late 15th century and claimed for Spain.  In the 17th century the Dutch gained control, and in 1845 the islands  became the Netherlands Antilles. In 1954 they became an integral part of  The Netherlands, with full autonomy in domestic affairs. Aruba seceded  from the federation in 1986.</p><p>Neto Vna-tu\, (Antonio) Agostinho (b.

In 1948 Neto joined a movement  aimed at rediscovering indigenous Angolan culture. He studied medicine  in Lisbon and returned to Angola in 1959 as a doctor. In 1960 he was  arrested in the presence of his patients by colonial authorities, who opened  fire when the patients protested. He was imprisoned in Portugal for two  years before escaping to join the Marxist Movimento Popular de Liber-  ta^ao de Angola (MPLA), whose president he became in 1962.

One of Neumann�s best works was the pilgrimage  church at Vierzehnheiligen (1743-53). A master of the late Baroque style,  he made ingenious use of domes and barrel vaults to create sequences of  round and oval spaces possessing an airy elegance lit by huge windows;  the lively interplay of these elements was accented by lavish use of deco�  rative plasterwork, gilding, statuary, and murals.</p><p>Neumann, John von See John von Neumann</p><p>neural network Type of parallel computation in which computing  elements are modeled on the network of neurons that constitute animal  nervous systems. This model, intended to simulate the way the brain pro�  cesses information, enables the computer to �learn� to a certain degree.  A neural network typically consists of a number of interconnected pro�  cessors, or nodes. Each handles a designated sphere of knowledge, and  has several inputs and one output to the network. Based on the inputs it  gets, a node can �learn� about the relationships between sets of data,  sometimes using the principles of fuzzy logic. For example, a backgam�  mon program can store and grade results from moves in a game; in the  next game, it can play a move based on its stored result and can regrade  the stored result if the move is unsuccessful. Neural networks have been  used in pattern recognition, speech analysis, oil exploration, weather pre�  diction, and the modeling of thinking and consciousness.</p><p>neural tube defect Congenital defect of the brain or spinal cord from  abnormal growth of their precursor, the neural tube (see embryology), usu-</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1348 I neuralgia &#x25BA; Neuschwanstein Castle</p><p>L_</p><p>N</p><p>ally with spine or skull defects. The tube may fail to close properly, have  parts missing, or have a blockage (see hydrocephalus). In spina bifida, ver�  tebrae are open over the back of the spinal cord, usually at the base. This  may not affect function if no further defects (local absence of skin or  meninges, protrusion of tissue, defect opening into the spinal cord) exist.  The more serious forms can cause paralysis and impair bladder and bowel  function. In encephalocele, a meningeal sac containing brain tissue pro�  trudes from the skull. The effects depend on the amount of tissue involved.  Adequate folic-acid intake by women of childbearing age reduces the risk  of neural tube defects. Early surgery can prevent or minimize disability.</p><p>neuralgia \nyu-'ral-jo\ Pain of unknown cause in the area covered by  a peripheral sensory nerve. In trigeminal neuralgia (tic douloureux), brief  attacks of severe shooting pain along a branch of the trigeminal nerve (in  front of the ear) usually begin after middle age, more often in women.  Initially weeks or months apart, they become more frequent and easily  triggered by touching the affected area, talking, eating, or cold. Analge�  sics help, but permanent cure requires surgery. Glossopharyngeal neural�  gia causes recurring severe pain, most often in men over 40. Excruciating  pains begin in the throat and radiate to the ears or down the neck, with  or without a trigger (e.g., sneezing, yawning, chewing). Usually separated  by long intervals, attacks subside before analgesics take effect. Surgery  may help in extreme cases. See also neuritis.</p><p>Neurath Vnoi-ratA, Konstantin, baron von (b. Feb. 2, 1873,  Klein-Glattbach, Ger.�d. Aug. 14, 1956, Enzweihingen, W.Ger.) German  diplomat. He entered the diplomatic service in 1903 and served as min�  ister to Denmark (1919-22), ambassador to Italy (1922-30), and ambas�  sador to Britain (1930-32). As Germany�s foreign minister (1932-38), he  lent respectability to Adolf Hitler�s expansionist foreign policy. As �pro�  tector� of Bohemia and Moravia (1939�41), he was accused of being too  lenient and was replaced by Reinhard Heydrich. After World War II, he was  tried and imprisoned for war crimes (1946-54).</p><p>neuritis \nyu-'ri-tos\ Inflammation of one or several nerves. The cause  may be mechanical, vascular, allergic, toxic, metabolic, or viral.  Symptoms�tingling, burning, or stabbing pains with sensory nerves and  anything from muscle weakness to paralysis with motor nerves�are usu�  ally confined to the part of the body served by the inflamed nerve. In Bell  palsy, facial nerve inflammation causes a characteristic facial muscle dis�  tortion. Analgesics can relieve the pain. Once the underlying cause is  treated, recovery is usually rapid but may be incomplete in severe cases,  with residual motor and sensory disturbances. See also neuralgia.</p><p>neurology Medical specialty concerned with nervous system function  and disorders. Clinical neurology began in the mid-19th century, when  mapping of the functional areas of the brain first began and understand�  ing of the causes of conditions such as epilepsy improved. The develop�  ment of electroencephalography in the 1920s aided in the diagnosis of  neurological disease, as did the development of computed axial tomogra�  phy in the 1970s and nuclear magnetic resonance imaging in the 1980s. In  addition to dealing with physical disorders (e.g., tumours, trauma), neu�  rology is unique among medical specialties in its intersection with psy�  chiatry. Greater understanding of the brain chemistry of disorders such as  schizophrenia and depression has led to a wide array of effective drugs that  nevertheless work best in conjunction with psychotherapy. Side effects of  drug or surgical therapy can be serious, and many nervous system disor�  ders have no effective treatment.</p><p>neuron or nerve cell Any of the cells of the nervous system. Sensory  neurons relay information from sense organs, motor neurons carry  impulses to muscles and glands, and intemeurons transmit impulses  between sensory and motor neurons. A typical neuron consists of den�  drites (fibres that receive stimuli and conduct them inward), a cell body  (a nucleated body that receives input from dendrites), and an axon (a fibre  that conducts the nerve impulse from the cell body outward to the axon  terminals). Both axons and dendrites may be referred to as nerve fibres.  Impulses are relayed by neurotransmitter chemicals released by the axon  terminals across the synapses (junctions between neurons or between a  neuron and an effector cell, such as a muscle cell) or, in some cases, pass  directly from one neuron to the next. Large axons are insulated by a mye�  lin sheath formed by fatty cells called Schwann cells. Bundles of fibres  from neurons held together by connective tissue form nerves. See illustra�  tion opposite.</p><p>neuropathy \nu-'ra-po-the\ Disorder of the peripheral nervous system.  It may be genetic or acquired, progress quickly or slowly, involve motor,</p><p>sensory, and/or autonomic (see autonomic nervous system) nerves, and  affect only certain nerves or all of them. It can cause pain or loss of sen�  sation, weakness, paralysis, loss of REFLEXes, muscle atrophy, or, in auto�  nomic neuropathies, disturbances of blood pressure, heart rate, or bladder  and bowel control; impotence; and inability to focus the eyes. Some types  damage the neuron itself, others the myelin sheath that insulates it.  Examples include carpal tunnel syndrome, amyotrophic lateral sclerosis,  poliomyelitis, and shingles. Causes include diseases (e.g., diabetes melutus,  leprosy, syphilis), injury, toxins, and vitamin deficiency (e.g., beriberi). See  also neuralgia; neuritis.</p><p>neuropsychology Science concerned with the integration of psycho�  logical observations on behaviour with neurological observations on the  central nervous system (CNS), including the brain. The field emerged  through the work of Paul Broca and Carl Wernicke (1848-1905), both of  whom identified sites on the cerebral cortex involved in the production or  comprehension of language. Great strides have since been made in  describing neuroanatomical systems and their relation to higher mental  processes. The related field of neuropsychiatry addresses itself to disor�  ders such as aphasia, Korsakoff syndrome, Tourette syndrome, and other  CNS abnormalities. See also laterality.</p><p>neurosis Mental and emotional disorder that affects only part of the per�  sonality, is accompanied by a less distorted perception of reality than in  a psychosis, and is characterized by various physiological and mental dis�  turbances (such as visceral symptoms and impaired concentration). The  neuroses include anxiety attacks, certain forms of depression, hypochondri�  asis, hysterical reactions, obsessive-compulsive disorders, phobias, various  sexual dysfunctions, and some tics. They have traditionally been thought  to be based on emotional conflict in which a blocked impulse seeks  expression in a disguised response or symptom. Behavioral psychologists  regard them as learned, inappropriate responses to stress, which can be  unlearned.</p><p>neurotransmitter Chemical released by neurons to stimulate neigh�  bouring neurons, allowing impulses to be passed from one cell to the next  throughout the nervous system. A nerve impulse arriving at the axon ter�  minal of one neuron stimulates release of a neurotransmitter, which  crosses the microscopic gap (see synapse) in milliseconds to the adjoin�  ing neuron�s dendrite. Many chemicals are believed to act as neurotrans�  mitters. The few that have been identified include acetylcholine, dopamine,  and serotonin. Some neurotransmitters activate neurons; others inhibit  them. Some mind-altering drugs act by changing synaptic activity.</p><p>Neuschwanstein Vnoi-'shvan-.shtlnV Castle Elaborate castle built on  a rock ledge over the Pollat Gorge in the Bavarian Alps, near Fiissen, Ger.  Begun in 1869 at the behest of Bavaria�s Louis II, this lavish stronghold is  an eccentric romantic reconstruction of a medieval castle, complete with</p><p>Structure of a neuron. Dendrites, usually branching fibres, receive and conduct  impulses to the cell body, where inputs arriving from various dendrites are inte�  grated. Nerve impulses are conducted along the axon. When an impulse reaches  the axon terminals, neurotransmitter chemicals are released into a gap (synapse)  between the neuron and a neighbouring cell, and the impulse is transmitted to an  adjacent neuron or effector cell (as of a muscle or gland). Schwann cells surround  large axons, forming an insulating sheath. Spaces (nodes of Ranvier) between  Schwann cells serve to conduct the nerve impulse quickly along the axon.</p><p>� MERRIAM-WEBSTER INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Neusiedler Lake &#x25BA; Neville I 1349</p><p>a walled courtyard, indoor garden, towers, and an artificial cave.

The eastern kingdom was Austrasia. Neustria corresponded roughly to the  area of present-day France west of the Meuse River and north of the Loire  River. The name later denoted a much smaller area; by the 11th�12th cen�  turies it was sometimes used synonymously with Normandy.</p><p>neutering See castration</p><p>Neutra Vnoi-tra,\ English Vnii-troX, Richard (Joseph) (b. April 8,  1892, Vienna, Austria�d. April 16, 1970, Wuppertal, W.Ger.) Austrian-  born U.S. architect. Educated in Vienna and Zurich, Neutra moved to the  U.S. in 1923. His most important early work was the Lovell House, Los  Angeles (1927-29), which features glass expanses and cable-suspended  balconies. Shortly after World War II, Neutra created his most memorable  works: the Kaufmann Desert House, Palm Springs, Calif. (1946-47), and  the Tremaine House, Santa Barbara, Calif. (1947�48). Elegant and pre�  cise, these houses are considered exceptionally fine examples of the Inter�  national Style, which Neutra helped introduce into the U.S. Carefully  placed in the landscape, Neutra�s houses often have patios or porches that  make the outdoors seem part of the house. He believed that architecture  should be a means of bringing man back into harmony with nature and  with himself and was particularly concerned that his houses reflect the  way of life of the owner. His later works included office buildings,  churches, housing projects, and cultural centres. His many writings  include Survival Through Design (1954).</p><p>neutralism See nonaligned movement</p><p>neutrality Legal status of a country arising from its abstention from all  participation in a war between other countries, the maintenance of an atti�  tude of impartiality toward the belligerents, and the recognition by the  belligerents of this abstention and impartiality. Historically, the rights of  neutral countries typically included freedom from use or occupation of  their territory by any warring party, maintenance of diplomatic relations  with other neutrals and belligerents, freedom of their citizens to go about  their business, and respect for their intent to be neutral. In both World  War I and World War II, many of the basic concepts of neutrality ceased  to be respected, and by the late 20th century the freedom of the neutral  had been sharply reduced.</p><p>neutrino \nii-'tre-no\ Fundamental particle with no electric charge, little  mass, and a spin value of Vi. Neutrinos belong to the lepton family of sub�  atomic particles. There are three types of neutrino, each associated with a  charged lepton: the electron, the muon, and the tau. Neutrinos are the most  penetrating of subatomic particles because they react with matter only by  the weak force. They do not cause ionization, because they are not elec�  trically charged. All types of neutrino have masses much smaller than their  charged partners.</p><p>neutrino \nu-'tre-no\ problem, solar Shortfall in the expected num�  ber of neutrinos produced by the Sun that are detected on Earth. Long-  running experiments begun in the 1960s found only one-third to two-  thirds the number of neutrinos predicted by theory to arrive from the Sun,  where they are emitted as a result of nuclear fusion in the solar core. The  discrepancy implied either that the theory of solar energy production was  wrong or that neutrinos transformed en route to Earth in a way that made  some of them seem to vanish. By the early 2000s strong evidence had  been gathered in support of the latter explanation�that neutrinos �oscil�  late� in flight among their different types, not all of which could be  detected in the experiments. For this to occur, neutrinos must have at least  a tiny mass, though the specific values remained to be determined.</p><p>neutron One of the constituent particles of every atomic nucleus except  ordinary hydrogen. Discovered in 1932 by James Chadwick (1891-1974),  it has no electric charge and has nearly 1,840 times the mass of the elec�</p><p>tron. Free neutrons undergo beta decay with a half-life of about 10 min�  utes. Thus, they are not readily found in nature, except in cosmic rays.  They are a penetrating form of radiation. When bombarded with neutrons,  various elements undergo nuclear fission and release more free neutrons.  If enough free neutrons are produced, a chain reaction can be sustained.  This process led to the development of nuclear power as well as the atomic  bomb. Neutron beams produced in cyclotrons and nuclear reactors are  important probes of matter, revealing details of structure in both organic  and inorganic susbtances.</p><p>neutron bomb or enhanced radiation warhead Small ther�  monuclear weapon that produces minimal blast and heat but releases large  amounts of lethal radiation. The blast and heat are confined to a radius of  only a few hundred yards; within a somewhat larger area, the bomb throws  off a massive wave of neutron and gamma radiation, which is extremely  destructive to living tissue. Such a bomb could be used with deadly effi�  ciency against tank and infantry formations on the battlefield without  endangering towns or cities only a few miles away. It can be carried in a  missile or delivered by a howitzer or even an attack aircraft.</p><p>neutron star Any of a class of extremely dense, compact stars thought  to be composed mainly of neutrons with a thin outer atmosphere of pri�  marily iron atoms and electrons and protons. Though typically about 12  mi (20 km) in diameter, they have a mass roughly twice the Sun�s and  thus extremely high densities (about 100 trillion times that of water).  Neutron stars have very strong magnetic fields. A solid surface differenti�  ates them from black holes. Below the surface, the pressure is much too  high for individual atoms to exist; protons and electrons are compacted  together into neutrons. The discovery of pulsars in 1967 provided the first  evidence of the existence of neutron stars, predicted in the early 1930s  and believed by most investigators to be formed in supernova explosions.  See also white dwarf star.</p><p>Neva \nye-'va\ River River, northwestern Russia. It flows 46 mi (74  km) from Lake Ladoga west to the Gulf of Finland in the Baltic Sea.

Its banks were the scene of a  battle in 1240 in which Alexander Nevsky, prince of Novgorod, defeated  the Swedes.</p><p>Nevada State (pop., 2000: 1,998,257), western U.S. Bordered by  Oregon, Idaho, Utah, Arizona, and California, it covers 110,567 sq mi  (286,368 sq km); its capital is Carson City. The Black Rock Desert is in  the northwest; the Colorado River forms its extreme southeastern bound�  ary. Human settlement in the area has spanned more than 20,000 years,  and evidence of prehistoric inhabitants include dwelling remains and rock  art. Early inhabitants included the Shoshone and Paiute Indians. Spanish  missionaries in the 18th century and fur traders in the 1820s arrived before  major exploration and mapping were done by John C. Fremont and Kit  Carson (1843�45). Nevada was part of the land ceded to the U.S. by  Mexico in 1848 and was included in the Utah Territory (1850-61). Settle�  ments increased after the discovery of the Comstock Lode, a rich silver  deposit, at Virginia City in 1859. It became the Territory of Nevada in  1861 and the 36th U.S. state in 1864. It began its transition to a modern  economy during the Great Depression when gambling was legalized. Con�  struction of the Hoover Dam aided the economy of southern Nevada. In  the 1950s the state became the main testing site for atomic-energy experi�  ments. The traditional bases of its economy, mining and agriculture, are  overshadowed by government activity and tourism, the latter centred on  Us Vegas, Reno, and Lake Tahoe.</p><p>Nevelson, Louise orig.

She studied at New York�s Art Students League and with Hans Hofmann  in Munich (1931). Her early figurative sculptures feature blockish, inter�  locking masses and found objects that anticipate her mature style. By the  1950s she was working almost exclusively in abstract forms. She is best  known for the large, monochromatic abstract sculptures of this period,  consisting of open-faced wooden boxes stacked to make freestanding  walls. Within the boxes are highly suggestive collections of abstract�  shaped objects mingled with pieces of architectural debris and other found  objects skillfully arranged to produce a sense of mystery and then painted  a single colour, usually black.

Bordered by the U.S. and the Cana�  dian province of Quebec, it lies on the Gulf of St. Lawrence and the  Northumberland Strait (east) and the Bay of Fundy (south); it is connected  with Nova Scotia by the Isthmus of Chignecto. Its capital, Fredericton, is  home to the University of New Brunswick (founded 1785; Canada�s old�  est university). New Brunswick was part of the original Acadia; it was  colonized by the French in the 18th century, then captured by the British,  who expelled the French-speaking Acadians in 1755 and incorporated the  area into Nova Scotia. After the American Revolution, some 14,000 loy�  alists from the U.S. settled there. As a result of this large influx, it was  separated from Nova Scotia, and the province of New Brunswick was  established in 1784. In 1867 it became an original member of the Domin�  ion of Canada. Forests cover 90% of the province, whose major cities  include Saint John and Moncton. Forestry and lumbering are the largest  industries, followed by commercial fishing.</p><p>New Brunswick, University of Canadian public university in Fre�  dericton, founded in 1785.

It consists of the islands of New Cale�  donia and Walpole, the Isle of Pines, and several other island groups. Its  capital is Noumea. The main island, New Caledonia, has rich deposits of  nickel that are among the largest in the world. Archaeological excava�  tions indicate an Austronesian presence in the area c. 2000-1000 bc. The  islands were visited by Capt. James Cook in 1774 and by various naviga�  tors and traders in the 18th�19th century. They were occupied by France  in 1853 and were a penal colony from 1864 to 1897. New Caledonians  joined the Free French cause of Charles de Gaulle in 1940; the islands were  the site of Allied bases during the Pacific war. They became a French  overseas territory in 1946. In 1987 residents voted by referendum to  remain part of France.</p><p>New Church or Swedenborgians Church whose members follow  the teachings of Emanuel Swedenborg. Swedenborg did not himself found  a church, but he believed that his writings would be the basis of a �new  church,� which he associated with the �new Jerusalem� mentioned in the  Book of Revelation. In 1788, soon after his death, a group of his follow�  ers established a church in London. The first Swedenborgian society in</p><p>the U.S. was organized in Baltimore in 1792. Baptism and the Lord�s  Supper are the two sacraments of the church, and New Church Day (June  19) is added to the established Christian festivals. There are three New  Church groups: the General Conference of the New Church, the General  Convention of the New Jerusalem in the U.S.A., and the General Church  of the New Jerusalem.</p><p>New Comedy Greek drama from c. 320 bc to the mid-3rd century bc  that offers a mildly satiric view of contemporary Athenian society. Unlike  Old Comedy, which parodies public figures and events (see Aristophanes),  New Comedy features fictional average citizens in domestic life. The  chorus, the representative of forces larger than life, is reduced to a small  band of musicians and dancers. Plays usually involve the conventional�  ized situation of thwarted lovers and contain stock characters. Menander  introduced the New Comedy and became its most famous exponent; Plau�  tus and Terence translated its plays for the Roman stage. Elements of New  Comedy influenced European drama down to the 18th century.</p><p>New Criticism or formalism Post-World War I school of Anglo-  American literary theory that insisted on the intrinsic value of a work of  art and focused attention on the individual work alone as an independent  unit of meaning. New Critics were opposed to the practice of bringing  historical or biographical data to bear on the interpretation of a work. The  primary critical technique was analytic (or �close�) reading of the text,  concentrating on its language, imagery, and emotional or intellectual ten�  sions. Critics associated with the movement include I. A. Richards, Wil�  liam Empson, John Crowe Ransom, and R. P. Blackmur (1904-1965).</p><p>New Deal U.S. domestic program of Pres. Franklin Roosevelt to bring  economic relief (1933-39). The term was taken from Roosevelt�s speech  accepting the 1932 presidential nomination, in which he promised �a new  deal for the American people.� New Deal legislation was enacted mainly  in the first three months of 1933 (Roosevelt�s �hundred days�) and estab�  lished such agencies as the Civil Works Administration and the Civilian  Conservation Corps to alleviate unemployment, the National Recovery  Administration to revive industrial production, the Federal Deposit Insurance  Corp. and the Securities and Exchange Commission to regulate financial  institutions, the Agricultural Adjustment Administration to support farm  production, and the Tennessee Valley Authority to provide public power and  flood control. A second period of legislation (1935�36), often called the  second New Deal, established the National Labor Relations Board, the  Works Progress Administration, and the social security system. Some leg�  islation was declared unconstitutional by the U.S. Supreme Court, and  some programs did not accomplish their aims, but many reforms were  continued by later administrations and permanently changed the role of  government.

Formed in 1961 from the Co-operative Commonwealth Federation, it favours  a mixed public-private economy, broadened social benefits, and an inter�  nationalist foreign policy. It formed governments in Saskatchewan, Man�  itoba, and British Columbia intermittently from the 1940s to the 1990s, in  the Yukon Territory from the 1980s, and in Ontario in the 1990s. At the  national level, however, it has enjoyed only marginal success. The NDP  draws much of its support from the farmers of Manitoba and Saskatchewan  and the urban workers of British Columbia and Ontario.</p><p>New Economic Policy (NEP) Economic policy of the Soviet Union  (1921-28). A temporary retreat from the failed War Communism policy of  extreme centralization and doctrinaire socialism, the new measures  included the return of most agriculture, retail trade, and light industry to  private ownership (though the state retained control of heavy industry,  banking, transport, and foreign trade) and the reintroduction of money into  the economy. The policy allowed the economy to recover from years of  war. In 1928 chronic grain shortages prompted Joseph Stalin to begin to  eliminate private ownership of farmland and to collectivize agriculture  under state control, effectively ending the NEP. By 1931 state control was  reimposed over all industry and commerce.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>New England &#x25BA; New Mexico I 1351</p><p>New England Region, northeastern U.S. It consists of the states of  Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Con�  necticut and has an area of 66,667 sq mi (172,668 sq km).

With  the explorations by Samuel de Champlain, Jacques Marquette, La Salle, Louis  Jolliet, and others, the boundaries of New France expanded beyond the  lower St. Lawrence River to include the Great Lakes and the Mississippi  Valley. From 1689 rivalry between England and France affected their  possessions in North America. The French and Indian War (1754-63)  resulted in the cession of Canada and the territory east of the Mississippi  River to England and the territory west of the Mississippi to Spain, with  France keeping only the islands of St.-Pierre and Miquelon off the coast  of Newfoundland.</p><p>New Goa See Panaji</p><p>New Granada, Viceroyalty of Spanish viceroyalty in northwest�  ern South America during colonial times. The region was conquered by  the Spanish in the 16th century and was initially subject to the Viceroy�  alty of Peru. It became a separate viceroyalty�first established tempo�  rarily in 1717, and later permanently in 1739�that included the modem  countries of Colombia, Panama, Venezuela, and Ecuador. Its capital was  Santa Fe (modern Bogota). It was liberated from Spain in 1823.</p><p>New Guinea Indonesian Irian \,ir-e-'an\ Island, eastern Maay Archi-  peago, western Pacific Ocean, north of Australia. Divided roughly in half  between Indonesia (west) and Papua New Guinea (east), New Guinea is the  second largest island in the world (after Greenand). It is about 1,500 mi  (2,400 km) long and 400 mi (650 km) wide at its widest point, with an  area of about 309,000 sq mi (800,000 sq km). The terrain ranges from  lowland rainforest to fertile highlands and a rugged mountainous spine;  its climate is tropical. Copper and gold are its chief mineral resources.  The majority of the people of New Guinea are subsistence farmers.</p><p>New Hampshire State (pop., 2000: 1,235,786), northeastern U.S. One  of the New Eng and states, it is bordered by Canada and the U.S. states  of Maine, Massachusetts, and Vermont; the Atlantic Ocean lies to the  southeast. New Hampshire covers 9,283 sq mi (24,043 sq km); its capi�  tal is Concord. The Connecticut River forms its western boundary with  Vermont. The White Mountains in its central part contain Mount Wash�  ington. The region was inhabited by Algonquin Indians (see Algonquian  anguages) when the first English people settled near Portsmouth in 1623.  The area came under the jurisdiction of Massachusetts in 1641 and  became a separate crown colony in 1679. It was the first colony to declare  its independence from Britain in 1776. Following the nation�s establish�  ment, the state grew rapidly. Agriculture flourished and manufacturing  developed along the rivers. Portsmouth became a major shipbuilding cen�  tre. The economy is now based primarily on manufacturing and tourism,</p><p>although dairy farming and granite quarrying are also important. Because  it holds the nation�s earliest presidential primary, it has furnished the first  testing ground for many candidacies. Dartmouth and the University of  New Hampshire are two of the state�s prominent educational institutions.</p><p>New Haven City (pop., 2000: 123,626), south-central Connecticut,  U.S. A port of entry on Long Island Sound, it was originally settled in 1638  and became part of the colony of Connecticut in 1665. It was the co-capital  with Hartford until 1875. New Haven was sacked by loyalist forces during  the American Revolution (1779), and during the American Civil War it was a  centre of abolitionist activity (see abolitionism). A number of famous inven�  tors made the city a centre of industrial technology, including Charles  Goodyear, Eu Whitney, and Samuel F.B. Morse. It is the home of Yale Uni�  versity and several other educational and cultural institutions.</p><p>New Hebrides See Vanuatu</p><p>New Ireland formerly Neu-Mecklenburg \n6i- , me-kl3n-,berg\  Island and province (pop., 1999 est.: 111,906), Bismarck Archipeago,  Papua New Guinea. The island has an area of 3,340 sq mi (8,651 sq km)  and is about 200 mi (320 km) long. The terrain is largely mountainous.  The province includes many nearby smaller islands. It was discovered by  Dutch navigators in 1616 but was little known before 1884, when it  became part of a German protectorate. After World War I it was mandated  to Australia. The island was occupied by the Japanese in World War II.  When Papua New Guinea gained independence in 1975, it became part  of that country. Most of the inhabitants live in the north. Copra produc�  tion dominates commercial development.</p><p>New Jersey State (pop., 2000: 8,414,350), eastern U.S. Lying on the  Atlantic Ocean, it is bordered by New York, Delaware, and Pennsylva�  nia. It covers 7,790 sq mi (20,176 sq km); its capital is Trenton. The Hud�  son River forms its northeastern boundary; the De aware River, its western  boundary. Before European colonization, the region was inhabited by  Deaware Indian tribes. Although it was sighted by Giovanni Verrazzano  and Henry Hudson, it was first settled by Dutch and Swedish traders. It  was the site of numerous battles during the American Revolution, includ�  ing one led by Gen. George Washington in 1776, after crossing the Dela�  ware (see Battles of Trenton and Princeton). It was the third state to ratify  the U.S. Constitution in 1787. Between the Revolutionary and Civil wars,  it underwent tremendous industrialization, abetted by the construction of  canals and, later, railways. Although known as the �Garden State,� a name  influenced by its 18th-century agricultural fertility, its economy is based  primarily on manufacturing, and it has many research facilities and labo�  ratories. Tourism, led by Atantic City, is also important. Chief cities  include Newark, Jersey City, Paterson, and Elizabeth.</p><p>New Mexico State (pop., 2000: 1,819,046), southwestern U.S. Bor�  dered by Mexico and the U.S. states of Colorado, Oklahoma, Texas, and  Arizona, it covers 121,598 sq mi (314,939 sq km); its capital is Santa Fe.

Human settlement in the area has probably spanned 10,000 years.  Before the Navajo and Apache arrived in the 15th century, an agricultural  Indian civilization had developed irrigation systems, pueblos, and cuff  dwellings, whose ruins still dot the state. Spaniards from Mexico claimed  the area for Spain in the 16th century, and in 1540 Francisco Vazquez de  Coronado explored it. The first settlement was at Santa Fe in 1610. Mis�  sionaries were active in the 1600s. It became part of Mexico in 1821 and  was ceded to the U.S. in 1848 at the end of the Mexican War. The Ter�  ritory of New Mexico was established by Congress in 1850. It became  the 47th U.S. state in 1912 and retained its frontier image. World War II  spurred economic and social change, bringing research facilities, includ�  ing that at Los Alamos. The economy today is largely dependent on the  export of raw materials and on federal government expenditures; oil and  natural gas are also important. The University of New Mexico and a fine  arts community are in Albuquerque.</p><p>New Model Army (1645) Army that won the English Civil Wars for  Parliament. It was formed to provide a well-trained force drawn from all  parts of England instead of the limited local militias. The new army also  replaced the private armies raised by individual generals that lacked a  unified command. Under Baron Fairfax and Oliver Cromwell, the New  Model Army won the Battle of Naseby and effectively ended the first phase  of the Civil Wars.</p><p>New Nationalism American political policy espoused by Theodore  Roosevelt. Influenced by Herbert Croly�s The Promise of American Life  (1910), Roosevelt used the phrase in a speech in which he tried to reconcile  the liberal and conservative wings of the Republican Party. New Nation�  alism called for federal intervention to promote social justice and the eco�  nomic welfare of the underprivileged. In 1912, as the presidential  candidate of the Progressive Party, Roosevelt ran unsuccessfully on a plat�  form based on the precepts of New Nationalism.

Founded in 1718 by French  colonist Jean-Baptiste Le Moyne de Bienville, it was ceded to Spain in 1763.  In 1800 it was ceded back to France and three years later sold to the U.S.  by Napoleon. Incorporated in 1805, it was the state capital from 1812 to  1849. During the American Civil War the city was captured and occupied  by Union forces (1862). A notable tourist centre, its attractions include  Mardi Gras and the French Quarter, a popular tourist area noted for its  nightclubs and Creole architecture and cuisine. It is also a medical, indus�  trial, and educational centre. It was devastated by Hurricane Katrina in  August 2005, when the levees protecting the city were breached and  nearly all the city was flooded.</p><p>New Orleans, Battle of (1815) Battle between the U.S. and Britain  during the War of 1812. Late in 1814 a British fleet of more than 50  ships commanded by Gen. Edward Pakenham (1778-1815) sailed into the  Gulf of Mexico and prepared to attack New Orleans. Gen. Andrew Jack-  son, commander of the U.S. Army of the Southwest, which consisted  chiefly of militiamen and volunteers, fought the British regulars who  stormed their position on Jan. 8, 1815. His troops were so effectively  entrenched behind earthworks and the British troops so exposed that the  fighting was brief, ending in a decisive U.S. victory, a British withdrawal,  and the death of Gen. Pakenham. The battle was without military value,  since the Treaty of Ghent ending the war had been signed in December,  but the news had been slow to arrive. The victory nevertheless raised  national morale, enhancing Jackson�s reputation as a hero and preparing  his way to the presidency.</p><p>New Orleans, Battle of (April 24-25, 1862) Naval action in the  American Civil War. A Union squadron of 43 ships led by David Farragut  entered the Mississippi River below New Orleans and breached the chain  cables stretched across the river as a defense. The 3,000 Confederate  troops under Mansfield Lovell withdrew northward and the city fell. The  Union army under Benjamin Butler entered the city on May 1 and began  an occupation that lasted until the end of the war. The loss of New Orleans  was a major blow to the Confederacy.</p><p>New Orleans jazz See Dixieland</p><p>New Realism Early 20th-century movement in metaphysics and episte�  mology that opposed the idealism dominant in British and U.S. universi�  ties. Early leaders included William James, Bertrand Russell, and G. E.</p><p>Moore, who adopted the term realism to signal their opposition to ideal�  ism. In 1910 William Pepperel Montague, Ralph Barton Perry, and oth�  ers signed an article entitled �The Program and First Platform of Six  Realists,� and followed it with a cooperative volume, The New Realism  (1912). In defending the independence of known things. New Realism  affirmed that in cognition �the content of knowledge, that which lies in  or before the mind when knowledge takes place, is numerically identical  with the thing known� (a form of direct realism). To some realists, this  epistemological monism seemed unable to give a satisfactory explanation  of the mind�s proneness to error.</p><p>new religious movement (NRM) Any religion originating in  recent centuries having characteristic traits including eclecticism and syn�  cretism, a leader who claims extraordinary powers, and a �countercul�  tural� aspect. Regarded as outside the mainstream of society, NRMs in  the West are extremely diverse but include millennialist movements (e.g.,  the Jehovah's Witnesses), Westernized Hindu or Buddhist movements (e.g.,  the Hare Krishna movement), so-called �scientific� groups (e.g., Scientol�  ogy), and nature religions (see Neo-Paganism). In the East they include  China�s 19th-century Taiping movement (see Taiping rebellion) and present-  day Falun Gong movement, Japan�s Tenrikyo and PL Kyodan, and Korea�s  Ch'ondogyo and Unification Church. Some NRMs fade away or meet  tragic ends; others, such as the Mormon church, eventually become  accepted as mainstream.</p><p>New Republic, The Weekly journal of opinion, founded in 1914 by  Willard Straight, with Herbert Croly as editor. Long one of the most  influential liberal magazines in the U.S., it early reflected the progressive  movement and sought reforms in U.S. government and society. Its popu�  larity declined in the 1920s when liberalism was out of favour but revived  in the 1930s. After initially opposing Pres. Franklin D. Roosevelt�s admin�  istration, it supported Roosevelt�s New Deal. After becoming editor in  1946, former U.S. vice president Henry Wallace moved the magazine fur�  ther left until he was forced to resign. In the early 1980s the magazine  began to display an array of commentary reflecting the resurgence of con�  servatism in U.S. politics.</p><p>New River River, southwestern Virginia and southern West Virginia,  U.S. It is formed in North Carolina and flows north across Virginia into  West Virginia, where it joins the Gauley River to form the Kanawha River.  It is about 255 mi (410 km) long and is spanned by one of the longest  steel-arch bridges in the world, the New River Gorge bridge near Fay�  etteville, W.Va., whose main span is 1,700 ft (518 m).</p><p>New School University formerly New School for Social  Research Private university in New York City. It was established in  1919 as an informal centre for adult education and soon became the first  American university to specialize in continuing education. In 1934 it estab�  lished a graduate faculty of political and social sciences, staffed mainly  by refugee academics from Nazi Germany. It also includes a liberal arts  college, a graduate school of management and urban policy, the Mannes  College of Music, and the Parsons School of Design.</p><p>New Siberian Islands Island group, Arctic Ocean, northeastern Rus�  sia, north of eastern Siberia. The islands divide the Laptev Sea from the  East Siberian Sea. They are separated from the Siberian mainland by  Dmitry Laptev Strait. With an area of about 14,500 sq mi (38,000 sq km),  they are snow-covered for more than nine months of the year. Arctic fox,  northern deer, lemming, and many species of birds inhabit the islands.</p><p>New South Wales State (pop., 2001: 6,609,304), southeastern Aus�  tralia. Bounded by Queensland, the Pacific Ocean, Victoria, and South Aus�  tralia, it has an area of 309,130 sq mi (800,640 sq km); the capital is Sydney.  The dominant geographic feature is the Great Dividing Range. Inhabited  from prehistoric times. New South Wales was claimed for Britain by Capt.  James Cook in 1770. The colony included the entire continent except for  Western Australia. The interior was explored throughout the 19th century  and colonies were set up there, separate from New South Wales. In 1901 it  became part of the Commonwealth of Australia. The state ceded the area of  the Australian Capital Territory in 1911. New South Wales is the centre of  commercial farming, industry, and culture in Australia.</p><p>New Spain, Viceroyalty of Former Spanish viceroyalty (1535�  1821), principally in North America. At various times it included what is  now the southwestern U.S. (as well as Florida and parts of the coast of  the Gulf of Mexico), Mexico, Central America north of Panama, much of  the West Indies, and the Philippines. Mexico City was the seat of the gov-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>New Sweden &#x25BA; New York City I 1353</p><p>ernment, which also had jurisdiction over Spain�s Caribbean possessions.

It was established by the New Sweden Co. led by  Peter Minuit in 1638, when Fort Christina was built at what is now Wilm�  ington, Del. It was captured by the Dutch in 1655 under Peter Stuyvesant.  The Swedish colonists were allowed to keep their lands and continue their  customs under Dutch rule.</p><p>New Testament Second of the two major divisions of the Christian  Bible. Christians see the New Testament as the fulfillment of the promise  of the Old Testament. It recounts the life and ministry of Jesus and inter�  prets their meaning for the early church, focusing especially on the new  covenant created between God and the followers of Jesus. There are 27  books in the New Testament: four Gospels, or stories of the life and teach�  ings of Christ; the Acts of the Apostles, a historical narrative of the first  years of the Christian church; 21 epistles, or letters of advice and instruc�  tion to early Christians; and the Book of Revelation, a description of the  coming apocalypse. Most were written in the later 1st century ad, though  none can be dated precisely. Only two authors are known for certain: St.  Paul, credited with 13 epistles; and St. Luke, writer of the third gospel and  the Book of Acts. Attributions of other authors range from highly likely  (for the other three gospels) to completely unknown (for the Epistle to the  Hebrews). These documents circulated among the early churches and  were used as preaching and teaching sources. The earliest known list of  the current New Testament canon dates from ad 367 in a work by St.  Athanasius. A church council of 382 gave final approval to the list.</p><p>New Thought Mind-healing movement that originated in the U.S. in  the 19th century. Its earliest proponent, Phineas P. Quimby (1802-66),  was a mesmerist who taught that illness is mental. New Thought was  influenced by philosophers ranging from Plato to Emanuel Swedenborg,  Georg Wilhelm Friedrich Hegel, and Ralph Waldo Emerson and in turn  influenced Mary Baker Eddy�s Christian Science. The International New  Thought Alliance (formed 1914) asserts that sin and illness stem from  incorrect thinking. New Thought groups emphasize Jesus as a teacher and  healer and proclaim his kingdom as being within each person.</p><p>new town Form of urban planning designed to relocate populations  away from large cities by grouping homes, hospitals, industry and cul�  tural, recreational, and shopping centers to form entirely new, relatively  autonomous communities. The new-town movement was anticipated by  the Utopian Ebenezer Howard in the early 20th century (see garden city).  The first official new towns were proposed in Britain�s New Towns Act  of 1946. The idea found favor in other countries, especially in the U.S.,  Western Europe, and Soviet Siberia. New towns outside Britain often  failed to incorporate enough of the mixed-use atmosphere that gives a  town vitality. A dramatic increase in commuting and use of the car obvi�  ated the need for new towns to be so self-contained.</p><p>New Wave French nouvelle vague Group of individualistic  French film directors of the late 1950s, including Claude Chabrol, Francois  Truffaut, Jean-Luc Godard, Louis Malle, Eric Rohmer, Alain Resnais, and oth�  ers. Most of the New Wave directors were associated with the important  film magazine Cahiers du Cinema, in which they developed the highly  influential auteur theory, calling for films to express the director�s per�  sonal vision. Their films were characterized by a brilliance of technique  that sometimes overshadowed the subject matter. Among the most impor�  tant New Wave films were Godard�s Breathless (1959), Truffaut�s The 400  Blows (1959), and Resnais�s Hiroshima mon amour (1959).</p><p>New World monkey Any of some 100 species of monkeys (the platyr-  rhine [�flat-nosed�] monkeys) that inhabit tropical Central and South  America. Platyrrhines have a broad nose, with a wide septum separating  the outwardly directed nostrils, and relatively unopposable thumbs. Most  species have a long tail, which in a few species is prehensile. They are  divided by zoologists into five families: the marmosets and tamarins; the  titis, sakis, and uakaris; the spider monkeys and woolly monkeys; the capu�  chin monkeys and squirrel monkeys; and the durukulis. See also Old World</p><p>MONKEY.</p><p>New Year's Day First day of the new year, celebrated with religious,  cultural, and social observances around the world. It is usually marked by</p><p>rites and ceremonies that symbolize casting off the old year and rejoicing  in the new. Most of the world recognizes January 1 as the start of a new  year because the Gregorian calendar, from its papal origin in 1582, has  become the international reference for treaties, corporate contracts, and  other legal documents. Nevertheless, numerous religious and national cal�  endars have been retained. For example, in the Persian calendar (used in  Iran and Afghanistan) New Year�s Day falls on the spring equinox (March  20 or 21 in the Gregorian calendar). The more widely employed Islamic  (Hijrl) calendar is based on 12 lunar months of 29 or 30 days; thus, the  Islamic New Year�s Day gradually regresses through the longer Grego�  rian calendar. The Hindu new year starts on the day following the first  new moon on or after the spring equinox. The Chinese new year begins  at sunset on the new moon in the sign of Aquarius (late January or early  February). The Hebrew calendar is based on 12 lunar months (13 in cer�  tain years) of 29 or 30 days; the Jewish New Year�s Day, or Rosh Ha-  shanah, can fall anytime from September 6 to October 5 in the Gregorian  calendar.</p><p>New York State (pop., 2000: 18,976,457), eastern U.S. It is bordered  by Canada and the U.S. states of Vermont, Massachusetts, Connecticut,  New Jersey, and Pennsylvania; Lake Erie and Lake Ontario are to the west  and the Atlantic Ocean to the southeast. New York covers 53,013 sq mi  (137,304 sq km); its capital is Albany. The Hudson, St. Lawrence, Dela�  ware, and Niagara rivers all form parts of its boundaries. The Adirondack  Mountains are in the northeast; the Catskills are in the east. Before  European colonization, Algonquins (see Algonquian languages) and Iro�  quois inhabited the area. In 1524 Giovanni Verrazzano visited New York  Bay. The 1609 explorations of Henry Hudson and Samuel de Champlain led  to settlement. In 1664 the Dutch colony, New Netherland, led by Peter  Stuyvesant, surrendered to the British and was renamed New York. The  French and Indian War resulted in skirmishes in northern and central New  York; its conclusion confirmed English dominance in the region. In the  American Revolution, it was the scene of many battles, including those of  Ticonderoga and Saratoga, and of Benedict Arnold�s treason at West Point.  New York adopted the first state constitution (1777). The capital moved  from New York City to Albany in 1797. The opening of the Erie Canal in  1825 spurred development of the western part of the state. In the 19th  century the growing influence in New York City of Tammany Hall caused  tension between the city and the state. The economy was once based  largely on manufacturing in cities, including Buffalo, Rochester, and Syra�  cuse. It is now dominated by service industries, concentrated in New York  City.</p><p>New York, State University of (SUNY) Largest university sys�  tem in the U.S. Founded in 1948, it consists of university centres in  Albany, Binghamton, Buffalo, and Stony Brook; colleges of arts and sci�  ences in Brockport, Buffalo, Cortland, Fredonia, Geneseo, New Paltz, Old  Westbury, Oneonta, Oswego, Plattsburgh, Potsdam, and Purchase; three  medical centres (two in New York City and one in Syracuse); several  two-year agricultural and technical colleges; a nonresidential continuing-  education program (Empire State College); over 30 community colleges;  and various other specialized units.</p><p>New York Central Railroad Major U.S. railroad. It was founded in  1853 to consolidate 10 railroads that paralleled the Erie Canal between  Albany and Buffalo, the oldest being the Mohawk and Hudson, New York  state�s first railway (established 1831). Cornelius Vanderbilt won control  of the New York Central in 1867 and combined it with his New York and  Hudson railroads running from Manhattan to Albany. The system grew  until it had 10,000 mi (16,000 km) of track linking New York with Bos�  ton, Montreal, Chicago, and St. Louis. The New York Central began to  decline after World War II, and in 1968 it merged with its chief competi�  tor, the Pennsylvania Railroad Co., to form the Penn Central Transporta�  tion Co. The merger failed, and the railroad was forced into bankruptcy  in 1970. Its passenger services were taken over by Amtrak in 1971, and  its other railroad assets were transferred to Conrail in 1976.</p><p>New York City City (pop., 2000: 8,008,278), southeastern New York,  at the mouth of the Hudson River. The largest city in the U.S. and an  important seaport, it consists of five boroughs: the Bronx, Brooklyn, Man�  hattan, Queens, and Staten Island. The site of a Dutch trading post on  Manhattan Island, it was colonized as New Amsterdam by Dutch direc�  tor general Peter Minuit, who bought it from the Indians in 1626. The  colony surrendered to the British in 1664 and was renamed New York. It  was the capital of the state (1784-97) and of the U.S. (1789-90).

In 1898 the five boroughs were merged into  a single city. Long a magnet for immigrants to the U.S., it is a centre of  world trade and finance, media, art, entertainment, and fashion. Because  of its prominence and its central role in world commerce, the city was a  target for acts of terrorism. In September 2001, hijackers intentionally flew  airliners into the twin towers of the World Trade Center, destroying them  and destroying or damaging several adjacent buildings; the attacks killed  some 2,800 people.

The company  is descended from the American Ballet, which was founded by George  Balanchine and Lincoln Kirstein in 1935 and revived as the Ballet Society  in 1946; it assumed its current name in 1948. Under Balanchine�s artistic  direction, the company became the leading U.S. ballet troupe, combining  European classical ballet with American characterization and innovation  and exerting enormous influence on American dance. It moved to its per�  manent home, the New York State Theater at Lincoln Center, in 1964.  Later artistic directors Jerome Robbins and Peter Martins contributed numer�  ous works to its repertoire. Its leading dancers have included Maria  Tallchief, Edward Villella, Jacques d'Amboise, and Suzanne Farrell.</p><p>New York Daily News Morning daily tabloid newspaper published  in New York City. It was founded in 1919 by Joseph Medill Patterson and  his cousin Robert McCormick as a subsidiary of the Tribune Co. of  Chicago. The first successful tabloid-format newspaper in the U.S., it  quickly attracted a large readership with sensational coverage of crime,  scandal, and violence; it also included lurid photographs, cartoons, and  entertainment features. It was an early user of wirephotos and developed  a large staff of photographers. In 1993 it was bought by Mortimer B.  Zuckerman.</p><p>New York Public Library Largest city public library in the U.S. and  one of the great libraries of the world. It was established in 1895, and its  central building opened in 1911. Its holdings include more than 10 mil�  lion books and more than 10 million manuscripts, as well as large col�  lections of pictures, maps, books for the blind, films, and microfilms.</p><p>New York school Painters who participated in the development of  contemporary art, particularly Abstract Expressionism, in or around New  York City in the 1940s and �50s. During and after World War II, leader�  ship in avant-garde art shifted from war-tom Europe to New York, and  the New York school maintained a dominant position in world art into the  1980s. Abstract Expressionism, Minimalism, Pop art, and the new realist  styles of the late 1960s, among others, all had their beginnings in New  York.

The exchange began as an informal meeting of 24 men in  1792 on what is now Wall Street in New York City. It was formally con�  stituted as the New York Stock and Exchange Board in 1817, and its  present name was adopted in 1863. Since 1868 membership has been  obtained by purchasing a seat from an existing member; membership has  been limited to 1,366 since 1953. The exchange provided capital for the  industrialization of the U.S. in the 19th century. After the Panic of 1837  it began to demand that companies disclose information about their  finances to the public as a condition of offering stock. The stock-market  crash of 1929 led to regulation by the Securities and Exchange Commission.  To be listed on the NYSE, a company must earn $2.5 million before taxes,  have more than one million shares of stock outstanding, give common  stockholders voting rights, and publish periodic financial statements.

From its establishment in 1851 it has aimed to avoid sen�  sationalism and to appeal to cultured, intellectual readers. In 1896 it was  bought by Adolph Ochs, who built it into an internationally respected  daily. Its prestige was notably enhanced by its coverage of the sinking of  the Titanic and of the two world wars. In the 1970s it became involved in  controversy with its publication of the Pentagon Papers. Later in the  decade, under the direction of Ochs�s grandson, Arthur Ochs Sulzberger,  its organization and staff underwent sweeping changes, including the  introduction of a national edition printed at regional sites. Today it is per�  haps the most respected and influential newspaper in the world. It is the  flagship of The New York Times Co., whose interests include other news�  papers (including the Boston Globe), magazines, and broadcast and elec�  tronic media.</p><p>New Yorker, The U.S. weekly magazine, famous for its varied liter�  ary fare and humour. It was founded in 1925 by Harold Ross, who was its  editor until 1951. Initially focused on New York City�s amusements and  social and cultural life, it gradually acquired a broader scope, encompass�  ing literature, current affairs, and other topics. Aimed at a sophisticated,  liberal audience, it became renowned for its short fiction, cartoons, major  (occasionally book-length) nonfiction pieces, and detailed reviews in the  arts. It was sold in 1985 to Samuel I. Newhouse, Jr. (see Newhouse fam�  ily). Since Ross, its editors have been William Shawn (1952-87), Robert  Gottlieb (1987-92), Tina Brown (1992-98), and David Remnick (from</p><p>1998).</p><p>New Zealand Island country, South Pacific Ocean.

Cur�  rency: New Zealand dollar. New Zealand</p><p>consists of the North Island and the South Island, which are separated by  Cook Strait, and several smaller islands. Both main islands are bisected  by mountain ranges. New Zealand has a developing market economy  based largely on agriculture (dominated by sheep raising), small-scale  industries, and services. It is a constitutional monarchy with one legisla�  tive house; its chief of state is the British monarch represented by the  governor-general, and the head of government is the prime minister.  Polynesian occupation dates to c. ad 1000. First sighted by Dutch explorer  Abel Janszoon Tasman in 1642, the main islands were charted by Capt.  James Cook in 1769. Named a British crown colony in 1840, the area was  the scene of warfare between colonists and native Maori through the  1860s. The capital was moved from Auckland to Wellington in 1865, and  in 1907 the colony became the Dominion of New Zealand. It administered  Western Samoa from 1919 to 1962 and participated in both World Wars.  When Britain joined the European Economic Community in the early 1970s,  its influence led New Zealand to expand its export markets and diversify  its economy. New Zealand also became more independent in its foreign  relations and took a strong stand against nuclear proliferation. The literacy  rate is nearly 100%. The cultural milieu is predominantly European,  although there has been a revival of traditional Maori culture and art, and  Maori social and economic activism have been central to political devel�  opments in New Zealand since the late 20th century.</p><p>Newar \'na-'war\ People living in the Kathmandu Valley in Nepal.

The  Newar population of Nepal is estimated to be about 540,000.</p><p>Newark Vnu-orkA City (pop., 2000: 273,546) and port of entry, north�  eastern New Jersey, U.S., west of New York City. It was founded in 1666  by Puritans and was chartered as a township in 1693. It was the site of  the College of New Jersey (1748-56; now Princeton University). In 1776  the city served as a supply base for Gen. George Washington. It was  incorporated as a city in 1836. The largest city in the state, it was the  scene of major civil disturbances in 1967. It is a highly diversified indus�  trial, transportation, and insurance centre. It was the birthplace of Aaron  Burr and Stephen Crane.</p><p>Newbery, John (b. 1713, Waltham St. Lawrence, Berkshire, Eng.�d.  Dec. 22, 1767, London) English publisher. In 1744 he set up a bookshop  and publishing house in London, and it became one of the first to pub�  lish children�s books, including A Little Pretty Pocket-Book and Little  Goody Two-Shoes. In 1781 his firm published the first collection of nurs�  ery rhymes associated with Mother Goose. He is commemorated by the  Newbery Medal, awarded annually since 1922 by the American Library  Association for the most distinguished contribution to children�s litera�  ture in the U.S. It is presented along with the Caldecott Medal (see Ran�  dolph Caldecott), awarded for the best children�s picture book.</p><p>Newcastle (-under-Lyme), Thomas Pelham-Holles, 1st  duke of (b. July 21, 1693�d. Nov. 17, 1768, London, Eng.) British  politician. He inherited lands from his father and uncle that by 1714 made  him one of the wealthiest Whig landowners in England. He helped bring  about the succession of George I, for which he received the title of duke  (1715). Chosen by Robert Walpole as secretary of state, he served from  1724 to 1754, then succeeded his brother Henry Pelham as prime minister  (1754-56, 1757-62). Noted for his skill in distributing patronage to secure  parliamentary support for a particular ministry, Newcastle wielded great  political influence in the reigns of George I and George II.</p><p>Newcastle (-upon-Tyne), William Cavendish, 1 st duke of</p><p>(b. c. 1593�d. Dec. 25, 1676, Welbeck, Nottinghamshire, Eng.) British  Royalist commander in the English Civil Wars. Through inheritances and  royal favour, he became very wealthy. In 1642 he was given command  of the four northern English counties and raised the siege of York (1642).  After the Royalist defeat at the Battle of Marston Moor, he left England  for France and Holland. He returned at the Restoration and regained his  estates. A patron of poets and dramatists, he also wrote several comedies.</p><p>Newcastle upon Tyne or Newcastle City and metropolitan bor�  ough (pop., 2001: 259,573), metropolitan county of Tyne and Wear, his�  toric county of Northumberland, northeastern England, on the River Tyne.  It dates from the Roman period and derives its name from the Norman  castle built in 1080 by Robert II of Normandy, the oldest son of William I  (the Conqueror). At first an important wool trade centre, it became a major  mining area and coal-shipping port in the 16th century. It was among the  world�s largest ship-repairing facilities; its economy now rests on asso�  ciated marine and heavy engineering industries. The city is also an edu�  cational centre and features a 14th-century church.</p><p>Newcomen Vnii-ko-monV Thomas (b. Feb. 28, 1663, Dartmouth,  Devon, Eng.�d. Aug. 5, 1729, London) British engineer. In 1712 he built  his atmospheric steam engine, a precursor of James Watt�s engine. In the  Newcomen engine, atmospheric pressure pushed the piston down after  the condensation of steam had created a vacuum in the cylinder. New�  comen engines were used for some years in the draining of mines and in  raising water to power waterwheels.</p><p>Newell, Allen (b. March 19, 1927, San Francisco, Calif., U.S.�d. July  19, 1992, Pittsburgh, Pa.) U.S. cognitive scientist. He taught at Carnegie  Mellon University from 1961 until his death. In the late 1950s and early  1960s he collaborated with Herbert Simon in constructing an influential  model of human problem solving (Human Problem Solving, 1972). His  later work was concerned with artificial intelligence, and he is known for  his development of computer models of human cognition and the devel�  opment of a unified theory of cognition (Unified Theories of Cognition,  1990). In 1992 he received the National Medal of Science.</p><p>Newfoundland Dog breed developed in Newfoundland, possibly  from crosses between native dogs and the Great Pyrenees dogs that  Basque fishermen introduced into North America in the 17th century.</p><p>Noted for sea rescues, the gentle, patient Newfoundland stands 26-28 in.  (66-71 cm) and weighs 110-150 lbs (50-68 kg). Powerful hindquarters,  a large lung capacity, large webbed feet, and a heavy, oily coat enable it  to swim in cold waters. It has also been used as a watchdog and draft  animal. The typical Newfoundland is solid black; the Landseer New�  foundland is usually black and white.</p><p>Newfoundland, Memorial University of See Memorial Univer�  sity of Newfoundland</p><p>Newfoundland Vnii-fond-londV and Labrador Province (pop.,  2001: 512,930), one of the four Atlantic provinces of Canada. Consisting  of the island of Newfoundland and Labrador on the mainland, and bounded  by Quebec, it extends into the North Atlantic Ocean and is the eastern�  most part of North America. Its capital is St. John's. It was originally  settled by Indians and Eskimos. Viking ruins from c. ad 1000 have been  found in the northern part of the island. John Cabot claimed the island for  England in 1497; the first colony was established at St. John�s in 1583.  France and England disputed possession of the area, and though England  retained control with the 1713 Peace of Utrecht, controversies over fish�  ing rights continued through the 19th century. A province since 1949, it  includes the Grand Banks fishing grounds. Fishing, mainly for cod, was  virtually the only industry until the early 20th century, when western  Labrador�s vast iron reserves began to be exploited.</p><p>Newhouse family Family that built a large publishing empire in the  U.S. in the late 20th century. The family�s fortunes began with Samuel  Irving Newhouse (1895-1979), who, as a clerk at age 17, made a failing  newspaper in Bayonne, N.J., profitable. From the early 1920s he bought  and turned around other papers; at his death his company, Advance Pub�  lications Inc., owned 31 newspapers, 7 magazines, 5 radio stations, 6 tele�  vision stations, and 15 cable television systems. Led by his sons Samuel  I. Newhouse, Jr. (b. 1928), and Donald E. Newhouse (b. 1930), Advance  Publications greatly expanded, buying several book publishers, including  Random House (sold to Bertelsmann AG in 1998), and becoming one of  the largest U.S. magazine publishers with titles such as The New Yorker,  Vanity Fair, Vogue, Glamour, Bride's, and Gourmet.</p><p>Newman, Arnold (Abner) (b. March 3,1918, New York, N.Y., U.S.)  U.S. photographer. He studied art at the University of Miami, then worked  in the photography studio of a Miami department store. In 1946 he opened  his own studio in New York City, where he specialized in portraits of well-  known people posed in settings associated with their work. His �environ�  mental portraiture� greatly influenced 20th-century portrait photography.  His best-known portraits include those of Max Ernst, Alfred Stieglitz, Geor�  gia O'Keeffe, Igor Stravinsky, Pablo Picasso, and Jean Cocteau.</p><p>Newman, Barnett orig. Baruch Newman (b. Jan. 29, 1905, New  York, N.Y., U.S.�d. July 3, 1970, New York City) U.S. painter. Bom to  Polish immigrant parents, he studied at the Art Students League and City  College. With Robert Motherwell and Mark Rothko, he cofounded the  school called �Subject of the Artist� (1948), which held open sessions  and lectures for other artists. He developed a style of mystical abstrac�  tion and achieved his breakthrough with Onement I (1948), in which a  single stripe (or �zip�) of orange vertically bisects a field of dark red. This  austerely geometric style became his trademark and had a great influence  on artists such as Ad Reinhardt and Frank Stella.</p><p>Newman, John Henry known as Cardinal Newman (b. Feb.  21, 1801, London, Eng.�d. Aug. 11, 1890, Birmingham, Warwick)  English churchman and man of letters. He attended the University of  Oxford, where in 1833 he became the leader of the Oxford Movement,  which stressed the Catholic elements in the English religious tradition and  sought to reform the Church of England. He was received into the Roman  Catholic church in 1845, but he came under suspicion among the more  rigorous clergy because of his quasi-liberal spirit. A challenge from  Charles Kingsley prompted him to write an eloquent exposition of his  spiritual history, the widely admired Apologia pro Vita Sua (1864). The  work assured his place in the church, and in 1879 he became a cardinal-  deacon. He also wrote theological works, religious poetry, and several  hymns, including �Lead, Kindly Light.�</p><p>Newman, Paul (b. Jan. 26, 1925, Cleveland, Ohio, U.S.) U.S. film  actor. He studied drama at Yale University and the Actors Studio and first  appeared on Broadway in Picnic (1953). In 1954 he made his screen debut  in the disastrous biblical epic The Silver Chalice.

He directed and produced films such  as Rachel, Rachel (1968) and The Glass Menagerie (1987), both of which  starred his wife, Joanne Woodward. In 1982 he launched the successful  �Newman�s Own� line of food products, with its profits going to a num�  ber of charitable causes.</p><p>Newport Town (pop., 1995 est.: 22,000), Isle of Wight, in the historic  county of Hampshire, England. It was probably the Roman settlement of  Medina; there is no trace of Saxon settlement. The first charter was  granted between 1177 and 1184, and the borough was incorporated in  1608. It is the Isle of Wight�s trade and agricultural centre.</p><p>Newport City (pop., 2000: 26,475) and port of entry, southeastern  Rhode Island, U.S., at the mouth of Narragansett Bay. Founded in 1639 by  colonists from Massachusetts, it became a haven for religious refugees.  With Providence, it was the joint capital of the state until 1900. Newport has  held many of the America's Cup yacht races, and it is a centre for naval edu�  cation. It also is the site of one of Cornelius Vanderbilt�s mansions (The  Breakers) and the Touro synagogue, which is the oldest in the U.S.</p><p>Newport Town, port, and county borough (pop., 2001 est.: 137,017),  historic county of Monmouthshire, Wales, at the Bristol Channel mouth of  the River Usk. By c. 1126 it was a medieval borough with a castle. The  city was chartered in 1385. It was industrialized in the 19th century and  was the scene of Chartist riots in 1839 (see Chartism). Industries include  steel and aluminum.</p><p>Newport News City (pop., 2000: 180,150) and port of entry, south�  eastern Virginia, U.S., at the mouth of the James River. The site was settled  in 1621 by 50 colonists from Ireland. It was incorporated as a city in 1896  and was an important embarkation point in both World Wars. With Nor�  folk and Portsmouth, it constitutes the Port of Hampton Roads. It is the site  of one of the largest shipyards in the world, producing luxury liners, air�  craft carriers, and nuclear-powered submarines.</p><p>Newry and Mourne District (pop., 2001: 87,058), southeastern  Northern Ireland. Bordered by the Irish Sea and the republic of Ireland,  it is divided in two by the Newry Canal, the first major canal in the Brit�  ish Isles, built 1730-41.

The administrative seat is at Newry.</p></section><section><p>news agency or news service or wire service Organization that  gathers, writes, and distributes news to newspapers, periodicals, radio and  television broadcasters, government agencies, and other users. It does not  publish news itself but supplies news to subscribers, who, by sharing  costs, obtain services they could not otherwise afford. All the mass media  depend on agencies for the bulk of the news they carry. Some agencies  focus on special subjects or on a local area or nation. Many news agen�  cies are cooperatives, with members providing news from their area to a  pool for general use. The largest news agencies are United Press Inter�  national, Associated Press, Reuters, and Agence France-Presse.</p><p>newscast Radio or television broadcast of news events. News gather�  ing and broadcasting by the radio networks began in the mid-1930s and  increased significantly during World War II. The television newscast  began in 1948 with 15-minute programs that resembled movie newsreels.  The current U.S. format employs a newscaster or anchorperson reading  news stories, with interpolated audiotape (for radio) or videotape (for  television) and live reports from remote journalists. Noted newscasters  have included Edward R. Murrow, Walter Cronkite, and David Brinkley.</p><p>Newsday Evening daily tabloid newspaper published in Long Island,  N.Y. It was established in 1940, as the residential suburbs in Nassau and  Suffolk counties began to expand. Following a liberal-independent policy,  it has specialized in reporting serious local news. The newspaper itself  has earned three Pulitzer Prizes for meritorious public service, and its  writers and reporters have earned many more. Newsday is owned by the  Tribune Co., which acquired the paper through its merger with the Times  Mirror Co.</p><p>newsgroup Internet forum for discussion of specific subjects. News-  groups are organized into subjects (e.g., automobiles); each typically has  several subgroups (e.g., classic cars. Formula One racing cars). A person  starts a threaded discussion by �posting� (uploading) an article; the</p><p>follow-up replies (including replies to replies) comprise the discussion. A  newsgroup name usually consists of an abbreviation (e.g., �rec� for the  recreation newsgroup) followed by subgroup names separated by dots  (e.g., �rec.music.jazz�). Viewing and posting messages requires a news  reader, a program that connects the user to an Internet news server. Most  newsgroups are connected via Usenet, a worldwide network that uses the  Network News Transfer Protocol (NNTP). See also bulletin-board system.</p><p>newspaper Publication usually issued daily, weekly, or at other regu�  lar times that provides news, views, features, and other information of  public interest and often carries advertising. Forerunners of the modern  newspaper appeared as early as ancient Rome (see Acta). More or less  regular papers printed from movable type appeared in Germany, Italy, and  the Netherlands in the early 17th century. The first English daily was The  Daily Courant (1702-35). Though preceded by official papers, James  Franklin�s New-England Courant (1721) was the first independent news�  paper in Britain�s North American colonies. By 1800 the principles of a  free press and a basic formula for both serious and popular papers were  taking root in much of Europe and the U.S. In the 19th century the num�  ber of U.S. papers and their circulations rose dramatically, owing to wider  literacy, broadening appeal, lower prices, and technological advances in  typesetting, printing, communications, and transport. By late in the cen�  tury, newspapers had achieved great power. Competition for readers often  led to sensationalism and, in the 20th century, gave rise to the so-called  tabloids (see yellow journalism). Since 1900 newspaper publishing world�  wide has expanded greatly; in large countries it has experienced consoli�  dation driven by media conglomerates or through the acquisitions of  smaller papers by larger ones.</p><p>Newsweek U.S. weekly newsmagazine, published in New York City.  Founded (as News-Week) in 1933 by Thomas J.C. Martyn, a former edi�  tor of Time, it merged with Today magazine in 1937. It initially offered a  rather drab survey of the news with columns of analysis. After World War  II it grew livelier, especially after its purchase by Philip Graham, pub�  lisher of The Washington Post, in 1961. It has a strong reputation for  accurate, brisk, and vivid reporting and, like Time , presents news in terse  summary form, organized by departments.</p><p>newt or eft Any of more than 40 salamander species (family Salaman-  dridae) prevalent in the southeastern  U.S. and Mexico and also found in  Asia and Great Britain. Aquatic spe�  cies are called newts; terrestrial spe�  cies are called efts. Newts have a  long, slender body, and the tail is  higher than it is wide. They eat earth�  worms, insects, snails, and other  small animals. Both aquatic and ter�  restrial species breed in ponds.

It is defined as the force neces�  sary to provide a mass of 1 kg with an acceleration of 1 m per second  per second. One newton is equal to a force of 100,000 dynes in the  centimetre-gram-second (CGS) system, or a force of about 0.2248 lb in  the foot-pound-second (English or U.S.) system. It is named for Isaac  Newton, whose second law of motion describes the changes a force can  produce in the motion of a body.</p><p>Newton, Huey P(ercy) (b. Feb. 17, 1942, Monroe, La., U.S.�d.

He met Bobby Seale (b. 1936) while attending  the San Francisco School of Law, and in 1966 they formed the Black Pan�  ther Party. In 1974 Newton was accused of murder and fled to Cuba; on  his return in 1977, he was freed after two trials ended in hung juries. In  1980 he received a doctorate in social philosophy from the University of  California at Santa Cruz.

Jan. 4, 1643, Woolsthorpe, Lincolnshire,  Eng.�d. March 31, 1727, London) English physicist and mathematician.  The son of a yeoman, he was raised by his grandmother. He was educated  at Cambridge University (1661-65), where he discovered the work of Rene  Descartes. His experiments passing sunlight through a prism led to the dis�  covery of the heterogeneous, corpuscular nature of white light and laid the  foundation of physical optics. He built the first reflecting telescope in 1668  and became a professor of mathematics at Cambridge in 1669. He worked  out the fundamentals of calculus, though this work went unpublished for  more than 30 years. His most famous publication, Principia Mathematica  (1687), grew out of correspondence with Edmond Halley. Describing his  works on the laws of motion (see Newton's laws of motion), orbital dynam�  ics, tidal theory, and the theory of universal gravitation, it is regarded as the  seminal work of modern science. He was elected president of the Royal  Society of London in 1703 and became the first scientist ever to be knighted  in 1705. During his career he engaged in heated arguments with several of  his colleagues, including Robert Hooke (over authorship of the inverse  square relation of gravitation) and G.W. Leibniz (over the authorship of cal�  culus). The battle with Leibniz dominated the last 25 years of his life; it is  now well established that Newton developed calculus first, but that Leibniz  was the first to publish on the subject. Newton is regarded as one of the  greatest scientists of all time.</p><p>Newton's law of gravitation Statement that any particle of mat�  ter in the universe attracts any other with a force ( F) that is proportional  to the product of their masses (m 1 and m 2 ) and inversely proportional to  the square of the distance ( R ) between them. In symbols: F = G(m l m 2 )/  R 2 , where G is the gravitational constant. Isaac Newton put forth the law  in 1687 and used it to explain the observed motions of the planets and  their moons, which had been reduced to mathematical form by Johannes  Kepler early in the 17th century.</p><p>Newton's laws of motion Relations between the forces acting on  a body and the motion of the body, formulated by Isaac Newton. The laws  describe only the motion of a body as a whole and are valid only for  motions relative to a reference frame. Usually, the reference frame is the  Earth. The first law, also called the law of inertia, states that if a body is  at rest or moving at constant speed in a straight line, it will continue to  do so unless it is acted upon by a force. The second law states that the  force F acting on a body is equal to the mass m of the body times its  acceleration a, or F = ma. The third law, also called the action-reaction  law, states that the actions of two bodies on each other are always equal  in magnitude and opposite in direction.</p><p>Newtown Saint Boswells Vnut- 3 n-s3nt-'baz-w3lz\ Village (pop.,  1991: 1,108), Scottish Borders council area, historic county of Roxburghs�  hire, southeastern Scotland.

Dec. 7, 1815, Paris) French army officer, the best-known of  Napoleon�s marshals. He distinguished himself in the French Revolution�  ary Wars and rose to general in 1799. A supporter of Napoleon, he was  created marshal of France in 1804 and duke d�Elchingen in 1808 after  victories in the Napoleonic Wars. He led French forces in the Battle of  Friedland (1807) and at the Battle of Borodino (1812). In the French retreat  from Moscow, he courageously commanded the exposed rear guard and  earned Napoleon�s praise as �the bravest of the brave.� After Napoleon�s  abdication, Ney favoured Louis XVIII but rallied to Napoleon�s support in</p><p>the Hundred Days and commanded troops at the unsuccessful Battle of  Waterloo. After the Bourbon Restoration, he was court-martialed and shot  by firing squad.</p><p>Neyshabur X.na-sha-'burX or NIshdpur \,ne-sh9-'pur\ Town (pop.,  1996: 158,847), northeastern Iran. Its name derives from its founder, the  Sasanian king Shapur I. One of the four great cities of the region of Kho-  rasan, it was the residence of the 5th-century Sasanian king Yazdegerd II.  It declined by the mid-7th century but flourished again under the Tahirid  (821-873) and Samanid (819-999) dynasties. It was the residence of the  Seljuq sultan Toghr'il Beg in the 11th century but again declined in the 12th  century. The tombs of the renowned poet and scholar Omar Khayyam and  the mystic poet Farid al-Dln 'Attar are nearby.</p><p>Nez Perce \'nez-'p9rs\ North American Indian people living mainly in  Idaho, U.S. Their language belongs to the Penutian language group, and  their traditional homeland is an area centring on the Snake River in central  Idaho, western Oregon, and western Washington. The name Nez Perce,  applied by French Canadian trappers, means �Pierced Noses�; they call  themselves Nimfipuu (Nee-me-poo), meaning �The Real People.� Their  culture was primarily that of the Plateau Indians, with some Plains Indian  influence. Their domestic life centred on small villages near streams with  abundant salmon; they also hunted small game and collected wild plant  foods. After acquiring horses, they began to hunt bison and became more  warlike, eventually becoming one of the dominant tribes in the region.  Through a series of treaties in the mid-1800s, their traditional territory was  severely reduced; the tragic Nez Perce War (1877), led by Chief Joseph, was  the result. At the turn of the 21st century, they numbered some 3,300.</p><p>Nezam? Vnez-.o-.meV or Nizam? orig. Ilyas Yusuf Nizam? Gan-  jaw? (b. c. 1141, Ganja, Seljuq empire�d. 1209, Ganja) Greatest roman�  tic epic poet in Persian literature. Little is known of his life, except that  he spent it in what is now Azerbaijan. Only a handful of his qasidahs  (odes) and ghazels have survived; his reputation rests on his great Kham-  seh (�The Quintuplet�), a group of five poems totaling 30,000 couplets,  in which he brought a colloquial and realistic style to the epic. The fourth  poem, The Seven Beauties, is considered his masterpiece.</p><p>NFL See National Football League</p><p>Ngami Voq-'ga-meV Lake Shallow lake, northwestern Botswana, north  of the Kalahari Desert.

Of noble birth, Diem was on  friendly terms with the Vietnamese imperial family and served as Emperor  Bao Dai�s minister of the interior (1933), but he resigned when the French  would not accept his legislative reforms. He turned down an invitation to  join Ho Chi Minh�s forces and lived in self-imposed exile until invited  back in 1954 by Bao Dai to serve as prime minister of South Vietnam. In  1955 he ousted the emperor and made himself president. He refused to  carry out elections mandated by the Geneva Accords of 1954, ruled auto�  cratically, and showed preference to fellow Roman Catholics in an over�  whelmingly Buddhist country.

Emperor  Gia Long (1762-1820), founder of the dynasty, conquered all of Vietnam  in 1802; his successors modeled their administration on the Chinese Qing  dynasty (1644-1911/12). The French invaded in 1858 and eventually took  control of the entire country.

Although Ni was born to wealth, he chose  not to serve the foreign Mongol dynasty of the Yuan and instead lived a  life of retirement and scholarship. He was characterized by his contem�  poraries as particularly quiet and fastidious, qualities that are found in his  art. In his paintings, usually landscapes, he used elements sparingly,  favoured ink monochrome, and left great areas of the paper untouched.  His works are characterized by a sombre quiet, and they often feature a  rustic hut, a few trees or other indications of plant life, and elemental  landforms.

It is preserved in  three main 13th-century manuscripts. Elements of great antiquity are dis�  cernible in the poem, traceable to Old Norse literature, stories in the Poetic  Edda, and Scandinavian sagas. The principal characters are Prince Sieg�  fried, Queen Brunhild, Princess Kriemhild, her brother King Gunther, and  his henchman Hagen; the story focuses on deceit, revenge, and slaughter.

Founded in 1204 by Theodore I Lascaris, it was the politi�  cal and cultural centre from which a restored Byzantium arose in the mid-  nth century under Michael VIII Palaeologus. It extended from the Black  Sea coast east of the Sangarius River southwest across western Anatolia  to Miletus and the Menderes (Maeander) River.

Capital: Managua. Most of the people are mestizos. Languages:  Spanish (official), indigenous Indian languages, English. Religion: Chris�  tianity (predominantly Roman Catholic; also Protestant). Currency: cor�  doba oro. Nicaragua�s western half consists of thickly forested mountain  ranges and fertile valleys. Parallel to the Pacific coast is a belt of about  40 dormant and active volcanoes. The eastern coastline along the Carib�  bean Sea is known as the Mosquito Coast. Earthquakes are common and  sometimes severe. Nicaragua has a developing market economy based  largely on agriculture, light industries, and trade. It is a republic with one  legislative house; its head of state and government is the president. The  area has been inhabited for thousands of years, most notably by the Maya.  Christopher Columbus arrived in 1502, and Spanish explorers discovered  Lake Nicaragua soon thereafter. Nicaragua was governed by Spain until  the early 1820s. It became a part of Mexico (1822-23) and then part of  the United Provinces of Central America until 1838, when full indepen�  dence was achieved. The U.S. intervened in political affairs by maintain�  ing troops there (1912-33). Ruled by the dictatorial Somoza family (1937�  79), Nicaragua was taken over by the Sandinista party after a popular  revolt. The Sandinistas were then opposed by armed insurgents, the U.S.-  backed Contras, from 1981. The Sandinista government nationalized sev�  eral sectors of the economy but lost national elections in 1990. The new  government reprivatized many public enterprises.

After an exhaustive study of all the major Buddhist  schools in Japan, he concluded in 1253 that the Lotus Sutra was the only  doctrine suitable for his age and predicted calamity for Japan if all other  sects were not abandoned. This pronouncement caused him to be ban�  ished from his monastery. He also claimed that Japan was the chosen  country of Buddhism, from which Buddhist salvation would spread to</p><p>other lands. He was later exiled to an island in the Sea of Japan, where  in 1272 he wrote his major work. Liberation from Blindness.</p><p>Nichiren Buddhism One of the largest schools of Japanese Buddhism,  founded by Nichiren. It believes that the essence of the Buddha�s teach�  ings are contained in the Lotus Sutra and that the beliefs of other Buddhist  schools are erroneous.

After Nichiren�s death the school  split into various subsects, notably Nichiren-shu, which controls the  temple founded by Nichiren at Mount Minobu, and Nichiren-sho-shu,  which is headquartered in a temple at the foot of Mount Fuji. Nichiren-  sho-shu has adherents in the U.S.; in Japan its lay organization is the  SOKA-GAKKAI.</p><p>Nicholas Russian Nikolay Nikolayevich (b. Nov. 18, 1856, St.  Petersburg, Russia�d.

As inspector general of cal�  vary (1895-1905), he introduced reforms in training and equipment. From  1905 he commanded the St. Petersburg military district, and in 1914 he  was appointed head of all Russian forces. A popular commander, he led  the army to early successes in World War I but was hampered by  shortages. Dismissed in 1915 by Nicholas II, he commanded in the Cau�  casus (1915-17). After the Russian Revolution of 1917 he moved to  France, where he led an organization to unite anticommunist Russian  emigres.</p><p>Nicholas, Saint or Santa Claus</p><p>Minor; feast day December 6) Minor  saint associated with Christmas.  Probably bishop of Myra, he is  reputed to have provided dowries for  three poor girls to save them from  prostitution and to have restored to  life three children who had been  chopped up by a butcher. He became  the patron saint of Russia and  Greece, of charitable fraternities and  guilds, and of children, sailors,  unmarried girls, merchants, and  pawnbrokers. After the Reformation  his cult disappeared in all the Prot�  estant countries of Europe except  Holland, where he was known as  Sinterklaas.

In 1825 he succeeded his brother Alexander I as emperor and sup�  pressed the Decembrist revolt. His reign came to represent autocracy, mili�  tarism, and bureaucracy. To enforce his policies, he created such agencies  as the Third Section (political police). In foreign policy, Nicholas quelled  an uprising in Poland (1830-31) and aided Austria against a Hungarian  uprising (1849). His designs on Constantinople led to war with Turkey  (1853) and drew other European powers into the Crimean War. He was  succeeded by his son Alexander II.</p><p>Nicholas II orig. Gerard of Burgundy (b. Lorraine�d. July 19/26,  1061, Florence) Pope (1058-61). Known as an advocate of reform, he  was bishop of Florence before being elected pope in opposition to the  antipope Benedict X. At the Lateran Council of 1059 he reformed the pro�  cess of papal election, placing it in the hands of the cardinals and limit�  ing the emperor�s role. The German bishops voided his decree (1061),  revealing growing tensions between empire and papacy. Nicholas brought  about a diplomatic revolution, which worsened relations with Germany  and its weak regent, when he sought an alliance with the Normans in  southern Italy and invested Robert Guiscard as duke of Apulia, Calabria,  and Sicily (1059). His legislation against clerical marriage and simony  was an important part of the Gregorian reform movement.</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1360 I Nicholas II &#x25BA; Nicolet</p><p>L_</p><p>N</p><p>Nicholas II Russian Nikolay Aleksandrovich (b. May 18, 1868,  Tsarskoye Selo, near St. Petersburg, Russia�d. July 16/17, 1918, Yeka�  terinburg) Tsar of Russia (1894-1917). Son of Alexander III, he received  a military education and succeeded his father as tsar in 1894. He was an  autocratic but indecisive ruler and was devoted to his wife, Alexandra,  who strongly influenced his rule. His interest in Asia led to construction  of the Trans-Siberian Railroad and also helped cause the disastrous Russo-  Japanese War (1904-05). After the Russian Revolution of 1905, he agreed  reluctantly to a representative Duma but restricted its powers and made  only token efforts to enact its measures. His prime minister, Pyotr Stolypin,  attempted reforms, but Nicholas, increasingly influenced by Alexandra  and Grigory Rasputin, opposed him. After Russia suffered setbacks in  World War I, Nicholas ousted the popular grand duke Nicholas as com�  mander in chief of Russian forces and assumed command himself, at the  bidding of Alexandra and Rasputin. His absence from Moscow and Alex�  andra�s mismanagement of the government caused increasing unrest and  culminated in the Russian Revolution of 1917. Nicholas abdicated in  March 1917 and was detained with his family by Georgy Y. Lvov�s pro�  visional government. Plans for the royal family to be sent to England were  overruled by the local Bolsheviks. Instead the family was sent to the city  of Yekaterinburg, where they were executed in July 1918.</p><p>Nicholas V orig. Tommaso Parentucelli (b. Nov. 15, 1397, Sar-  zana, Republic of Genoa�d. March 24, 1455, Rome) Pope (1447-55).  Soon after his election, he ended the schism caused by the rivalry between  popes and church councils. He restored peace to the Papal States, won  Poland�s allegiance, and gained the support of Austria by promising to  crown Frederick III as Holy Roman emperor. Nicholas initiated the Peace  of Lodi (1455) in order to end strife in Italy, and he tried to stamp out  simony and other corrupt practices in the church. A patron of art and  scholarship, he rebuilt many of Rome�s architectural treasures and  founded the Vatican Library. Although Nicholas was the first of the Renais�  sance popes, his failure to promote real religious reform helped bring  about the Reformation of the 16th century.</p><p>Nicholas Brothers U.S. tap-dancing duo.

July 3, 2000, New York, N.Y.) developed the  �classical tap� form, combining jazz dance, ballet, and acrobatics with  tap. They gained fame at a young age while dancing at Harlem�s Cotton  Club (1932-39); they went on to appear in films such as Stormy Weather  (1943), as well as on Broadway and later on television. They began their  careers at a time when opportunities were few and stereotyped roles the  norm for black entertainers, but they rose above this marginalization and  enhanced the art of tap with their elegance and sensational showmanship.</p><p>Nicholas of Cusa (b. 1401, Kues, Trier�d.

In On Catholic Concordance (1433), he supported  the supremacy of the general councils of the church over the papacy�s  authority (see conciliar movement). However, after witnessing the failure  of the Council of Basel to unify the church or enact reform, he reversed  his position and became an ardent supporter of the pope. Skilled in nearly  every branch of learning, he anticipated the work of Nicolaus Copernicus  by discerning a movement in the universe that did not centre on the Earth.  He also carried out botanical experiments and collected ancient manu�  scripts. In his discourse On Learned Ignorance (1440), he described the  learned man as one who is aware of his own ignorance.</p><p>Nicholas of Verdun (fl. c. 1150-1210, Flanders) French enamelist  and goldsmith, considered the greatest of his day.

He was  renowned for his enormous wealth. Seeking to end the Peloponnesian War  (431^-04), in 421 he negotiated a 50-year alliance (the Peace of Nicias),  which held for six years before the ambitions of Alcibiades led to renewed  warfare. In 415 Nicias reluctantly shared command of a Sicilian expedi�  tion with Lamachus and Alcibiades. When Alcibiades was recalled and  Lamachus died, Nicias, himself seriously ill, lost the advantage they had  achieved in the siege of Syracuse; when he tried to escape, his troops were  overwhelmed and he was captured and executed.</p><p>nickel Metallic chemical element, one of the transition elements, chemi�  cal symbol Ni, atomic number 28. Nickel is silvery white, tough, harder  than iron, ferromagnetic (see ferromagnetism), and highly resistant to rust�  ing and corrosion. It occasionally occurs free and is fairly common but  not often concentrated in igneous rocks. As pure metal, it is used to coat  other metals (see plating) and as a catalyst. In alloys, it is used in coins,  Monel metal, nickel silver, nickel-chrome and stainless steels, permanant  magnets, and cutlery. Its compounds, in which it most often has valence  2, have a variety of industrial uses, as catalysts and mordants (see dye)  and in electroplating.</p><p>Jan. 21, 1940, Columbus,</p><p>ft</p><p>Nicklaus \'nik-bs\, Jack (William) (b</p><p>Ohio, U.S.) U.S. golfer, one of the  greatest in the game�s history.

When the Ottoman Turks  besieged Constantinople (1395), Manuel II Palaeologus appealed to Europe  for help. The king of Hungary organized a crusade intended to expel the  Turks from the Balkans and then march to Jerusalem. The crusaders laid  siege to Nicopolis, the main Turkish stronghold on the Danube River, but  Turkish forces arrived from Constantinople and slaughtered most of the  crusaders. The battle ended international efforts to halt Turkish expansion  into the Balkans and central Europe.</p><p>Nicopolis \n3-'ka-p9-lis\ Actia Ancient city, northwestern Greece. Its  ruins lie about 4 mi (6 km) north of Preveza. It was founded in 31 bc by  Octavian (later Augustus) to commemorate his victory over Mark Antony  and Cleopatra at the Battle of Actium. It became the capital of the coastal  region, encompassing Acarnania and Epirus, and was famous for its build�  ings and for the Actian Games.

In 1810 he began a series of lectures at the Univer�  sity of Berlin that were the basis of his great work, the enormously influ�  ential History of Rome (1811-32). In it he introduced skepticism to  historical scholarship, showing how to analyze historical sources, discard  worthless material, and lay bare elements from which historical facts  could be reconstructed, and thereby initiating a new era in historiography.</p><p>Niebuhr Vne-.burX, Reinhold (b.

He was ordained in the Evangelical Synod of North</p><p>America in 1915 and served as pas�  tor of Bethel Evangelical Church in  Detroit, Mich., until 1928. His years  in that industrial city made him a  critic of capitalism and an advocate  of socialism. From 1928 to 1960 he  taught at New York�s Union Theo�  logical Seminary. His influential  writings, which forcefully criticized  liberal Protestant thought and  emphasized the persistence of evil in  human nature and social institutions,  include Moral Man and Immoral  Society (1932), The Nature and Des�  tiny of Man, 2 vol.

The  black sulfides are powdered, and after the engraved silver has been moist�  ened, the powder is spread on it. When the metal is heated, the niello  melts and runs into the engraved channels. After the excess niello is  scraped away, the surface is polished. The contrast of the black niello  against the bright surface produces an attractive decorative effect. During  the height of its popularity in the Renaissance, the technique was widely  used for embellishing liturgical as well as utilitarian objects. Nielli  (objects decorated with niello) were produced in ancient Rome and 9th-  century England. In Russia niello work is known as Tula work.</p><p>Nielsen, Carl (August) (b.

In 1890 he went to Germany to learn of newer developments and  met Johannes Brahms, whose music came to influence his own. His indi�  vidual style�still following classical forms but using intense chromati�  cism combined with a lyric, melodic strain�emerged after 1900. The last  five of his six symphonies (1902-25) are the core of his work, but he also  composed many short orchestra pieces, piano and chamber music, con�  certos for violin, flute, and clarinet, and a wind quintet.</p><p>Nielsen ratings National ratings of the popularity of U.S. television  shows. Developed by A.C. Nielsen in 1950, the system now samples tele�  vision viewing in about 5,000 homes. A meter attached to each television  set records the channel being watched and sends the data to a computer  centre; individual buttons record which person in each household is  watching a given program. Separate surveys are done for many large  media market areas. The ratings project each program�s total audience;  for example, a rating of 20 denotes that 20% of U.S. households tuned in  to a particular program. Commercial television networks use the ratings  to set advertising rates for each program as well as to determine which  programs to continue and to cancel.</p><p>Niemeyer Yne-.ml-arN (Soares Filho), Oscar (b. Dec. 15,1907, Rio  de Janeiro, Braz.) Brazilian architect. Beginning in 1934, he worked in  the office of Lucio Costa, an early exponent of the Modem movement in  Brazil. Niemeyer�s first major independent project was the plan for Pam-  pulha (1941), a suburb of Belo Horizonte. The project is notable for the  free-flowing forms used in many of its buildings. Other commissions fol�  lowed, and in 1947 Niemeyer represented Brazil in the planning of the  United Nations buildings in New York City. In 1956 Niemeyer was asked  to design the new capital city of Brasilia; he agreed to design the gov�  ernment buildings but suggested a national competition for the master  plan, a competition subsequently won by his mentor, Costa. Niemeyer  served as chief architect for NOVA-CAP, the government building author�  ity in Brasilia, from 1956 to 1961. Among the Brasilia buildings designed  by Niemeyer are the President�s Palace, the Brasilia Palace Hotel, the  presidential chapel, and the cathedral. Active into his nineties, he was  commissioned to design the mushroomlike Museum of Contemporary Art  in Niteroi, Braz. (1991). With its lyrical and sculptural forms, his work is  free-flowing and optimistic.

In 1813 he began experiments with  lithography. He is best remembered for his experiments with photogra�  phy, which he called heliography. In 1826-27, using a camera, he made  a view from his workroom window on a pewter plate�the first perma�  nently fixed image from nature. In 1829 he began a partnership with  L.-J.-M.

Oct. 15,1844,  Rocken, Saxony, Prussia�d. Aug. 25, 1900, Weimar, Thuringian States)  German-Swiss philosopher and writer, one of the most influential of mod�  ern thinkers. The son of a Lutheran pastor, he studied at Bonn and Leipzig  and at age 24 became professor of Classical philology at the University  of Basel. He became close to the older Richard Wagner, in whose operas  he saw the potential for the revival of Western civilization, but broke with  Wagner angrily in 1876. His Birth of Tragedy (1872) contained major  insights into ancient Greek drama; like Untimely Meditations (1873), it  is dominated by a Romantic perspective also influenced by Arthur  Schopenhauer. Mental and physical problems forced him to leave his posi�  tion in 1878, and he spent 10 years attempting to recover his health in  various resorts while continuing to write prolifically. His works from  Human, All Too Human (1878) to The Gay Science (1882) extol reason  and science, experiment with literary genres, and express his emancipa�  tion from his earlier Romanticism. His mature writings, particularly  Beyond Good and Evil (1886), A Genealogy of Morals (1887), and Thus  Spake Zarathustra (1883-92), were preoccupied with the origin and func�  tion of values in human life. If, as he believed, life neither possesses nor  lacks intrinsic value and yet is always being evaluated, then such evalu�  ations can usefully be read as symptoms of the evaluator�s condition. He  fulminated against Christianity and announced the death of God. His  major breakdown in 1889 marked the virtual end of his productive life.  He was revered by Adolf Hitler for his dislike of democracy and his heroic  ideal of the Ubermensch (Superman), though the Nazis perverted  Nietzsche�s thought and ignored much in it that was hostile to their aims.  His analyses of the root motives and values that underlie traditional West�  ern religion, morality, and philosophy affected generations of theologians,  philosophers, psychologists, poets, novelists, and playwrights.</p><p>Niger Vnl-jor, ne-'zher\ officially Republic of Niger Country, west�  ern Africa, on the southern edge of the Sahara.

Languages: French (official), Hausa, Arabic. Religions: Islam  (predominantly Sunni); also traditional beliefs. Currency: CFA franc. A  landlocked country, Niger is characterized by savanna in the south and  desert in the centre and north; most of the population lives in the south.  The Niger River dominates in the southwest and the Air Massif (a moun�  tainous region) in the north-central part of the country. Niger has a devel�  oping economy based largely on agriculture and mining. It is a republic  with one legislative body; its head of state and government is the presi�  dent, assisted by the prime minister. There is evidence of Neolithic cul�  ture in the region, and there were several precolonial kingdoms. First  explored by Europeans in the late 18th century, it became part of French  West Africa in 1904. It became an overseas territory of France in 1946  and gained independence in 1960. The first multiparty elections were held  in 1993. Ibrahim Bare Mainassara led a military coup in 1996, but after  his assassination in 1999 the country returned to democratic government.

Religions: Christianity (Protestant, other Christians, Roman  Catholic), Islam, traditional beliefs. Currency: naira. Nigeria consists of  plateaus and the lowlands between them, which are major river basins fed  especially by the Niger River. It has a developing mixed economy based  largely on petroleum production and agriculture; manufacturing is grow�  ing in importance. Services, trade, and transportation employ more than  two-fifths of the workforce. Nigeria is a federal republic with two legis�  lative bodies; its head of state and government is the president. Inhabited  for thousands of years, the region was the centre of the Nok culture from  500 bc to ad 200 and of several precolonial empires, including Kanem-  Bornu, Benin, and Oyo. The Hausa and Fulani also had states. Visited in  the 15th century by Europeans, it became a centre for the slave trade. The  area began to come under British control in 1861 and was made a British  colony in 1914. Nigeria gained independence in 1960 and became a  republic in 1963, with Nnamdi Azikiwe as president. Ethnic strife soon led  to military coups, and military groups ruled the country from 1966 to 1979  and from 1983 to 1999. Civil war between the federal government and  the former Eastern Region, Biafra (1967-70), ended in Biafra�s surrender  after the death by starvation of perhaps a million Biafrans.

The common nighthawk ( Chordeiles  minor), or bullbat, inhabits most of North America, migrating to South  America in winter. It is about 8-12 in. (20-30 cm) long and grayish  brown, with a white throat and wing patches. It has a sharp nasal call.  During courtship it dives swiftly, creating audible whirring sounds.</p><p>nightingale Any of several small Old World thrushes (family Turdi-  dae) renowned for their song. The  name refers in particular to the Eur�  asian nightingale ( Erithacus mega-  rhynchos), a brown bird, 6.5 in. (16  cm) long, with a rufous tail. It sings  day and night from perches in shub-  bery. Its strong and varied song, with  prominent crescendo effects, has  been regarded for centuries through�  out Europe and Asia as the most  beautiful of all birdsongs.

She  used her own finances to purchase supplies. She also spent many hours  in the wards; her night rounds giving personal care to the wounded estab�  lished her image as the �Lady with the Lamp.� Her efforts to improve  soldiers� welfare led to the Army Medical School and a Sanitary Depart�  ment in India. She started the first scientifically based nursing school, was  instrumental in setting up training for midwives and nurses in workhouse  infirmaries, and helped reform workhouses. She was the first woman  awarded the Order of Merit (1907).</p><p>nightjar or goatsucker Any of about 60-70 species of birds (family  Caprimulgidae) found almost worldwide in temperate to tropical regions.  The name is sometimes applied to all birds in the order Caprimulgiformes.  (The name goatsucker derives from an old belief that they sucked goat�s  milk at night.) Nightjars are gray, brown, or reddish brown. They eat fly�  ing insects at night. The common nightjar ( Caprimulgus europaeus ) has  a flat head; wide, bristle-fringed mouth; large eyes; and soft plumage that  results in noiseless flight. It is about 12 in. (30 cm) long. Its North Ameri�  can relatives include the nighthawk and whippoorwill.</p><p>nightshade family Family Solanaceae, composed of at least 2,400  species of flowering plants in about 95 genera. Though found worldwide,  the nightshades are most abundant in tropical Latin America. Many are  economically important as food or medicinal plants. Among the most  important are the potato, eggplant, tomato, garden pepper, tobacco, and  many garden ornamentals, including the petunia. The medicinally signifi�  cant nightshades are potent sources of such alkaloids as nicotine, atropine,  and scopolamine; they include deadly nightshade (belladonna), jimson-  weed ( Datura stramonium), henbane, and mandrake. The genus Solanum  contains almost half the species in the family. The species usually called  nightshade in North America and England is S. dulcamara, also called  bittersweet and woody nightshade.</p><p>nihilism Vnl-o-.li-zom, 'ne-o-.li-zomX Any of various philosophical posi�  tions that deny that there are objective foundations for human value sys�  tems. In 19th-century Russia the term was applied to a philosophy of  skepticism that opposed all forms of aestheticism and advocated utilitari�  anism and scientific rationalism; it was popularized through the figure of  Bazarov in Ivan Turgenev�s Fathers and Sons (1862). Rejecting the social  sciences, classical philosophical systems, and the established social order,  nihilism rejected the authority of the state, the church, and the family.

In 1912-13 he choreographed The Afternoon of a Faun,  Jeux, and The Rite of Spring, all of which caused scandals. His marriage  in 1913 led to his dismissal from the company by his mentor, Sergey  Diaghilev. He continued to perform but with less success. His intensify�  ing mental illness led to his retirement in 1919, and he lived mostly in  mental institutions in Switzerland, France, and England until his death.  His status as a legend is unequaled in the history of dance.</p><p>Nijmegen Vna-.ma-koV Treaties of (1678-79) Peace treaties that  ended the Franco-Dutch War. In the treaty between France and the Dutch  Republic, France agreed to return Maastricht and to suspend the anti-  Dutch tariff of 1667. In the treaty between France and Spain, Spain gave  up regions to France that gave it a protected northeastern border and  secured the safety of Paris. By negotiating separate treaties, France gained  advantages over its enemies in the war.</p><p>Nike Vnl-ke, 'ne-ka\ Greek goddess of victory. She was the daughter of  the giant Pallas and the river Styx.</p><p>Nike was originally an attribute of  both Athena and Zeus, represented as  a small figure carried in their hand.</p><p>She gradually came to be recognized  as a mediator between gods and mor�  tals, and was frequently shown car�  rying a palm branch, wreath, or staff  as the messenger of victory. When  depicted on her own, she was often  a winged figure hovering over the  victor in a competition. At Rome she  was worshiped as Victoria.</p><p>Nike Inc. U.S. sportswear com�  pany. It was founded in 1964 as Blue  Ribbon Sports by Bill Bowerman (b.</p><p>1911), a track-and-field coach at the  University of Oregon, and his former  student Phil Knight (b. 1938). They  opened their first retail outlet in 1966, launched the Nike brand shoe in  1972, and renamed the company Nike Inc. in 1978. In 1979 it claimed  50% of the U.S. running shoe market. In 1980 the company went public.  Part of Nike�s success is owed to endorsements by such athletes as John  McEnroe, Michael Jordan, and Mia Hamm. In the 1990s the company suf�  fered from revelations about conditions in its overseas factories, but it  remained a top producer of athletic shoes and clothing.</p><p>Nikon \'nye-kon\ orig. Nikita Minin (b. 1605, Veldemanovo,  Russia�d. Aug. 27, 1681, en route to Moscow) Leader of the Russian  Orthodox church. Born a peasant, he rose through the ranks of the priest�  hood to become patriarch of Moscow and all Russia in 1652. Granted  sovereign power during the absence of Tsar Alexis on military campaigns,  he purged Russian religious books and practices of what he considered</p><p>corruptions, and he exiled his opponents. His reforms troubled many  believers and led to a schism in the church (see Old Believers) as well as  to widespread disaffection (see Doukhobors), and his high-handedness  alienated Alexis. In 1666 a council of Greek patriarchs convened by  Alexis stripped Nikon of all priestly functions but retained his reforms.</p><p>Nile, Battle of the (Aug. 1, 1798) Battle between the British fleet  under Horatio Nelson and French Revolutionary forces at Abu Qlr Bay,  near Alexandria, Egypt. In a plan to constrict British trade routes by  invading Egypt, Napoleon ordered the French fleet to sail from its port  of Toulon to Alexandria. The French eluded the British fleet to reach Abu  Qlr Bay, where they anchored in a defensive line. Nelson discovered the  French at twilight and ordered an immediate attack. In an all-night battle,  the British destroyed or captured all but two of the 13 French ships. The  decisive victory isolated Napoleon�s army in Egypt and secured British  control of the Mediterranean.</p><p>Nile perch Large food and game fish (family Latidae) found in the Nile  and other African rivers and lakes. The Nile perch {hates niloticus ) has a  large mouth and is greenish or brownish above, silvery below. It grows  to about 6 ft (1.8 m) and weighs 300 lbs (140 kg). It has a slender body,  a protruding lower jaw, a rounded tail, and two dorsal fins. Other species  in the same family are found in African river systems and in Asian and  Australian estuaries and coastal waters. The members of the family are  sometimes classified with snooks (family Centropomidae).</p><p>Nile River Arabic Bahr al-NTl \bar-al-'nel\ River, eastern and north�  eastern Africa. The longest river in the world, it is about 4,132 mi (6,650  km) long from its remotest headstream (which flows into Lake Victoria)  to the Mediterranean Sea. After leaving the lake, it flows generally north  through Uganda, The Sudan, and Egypt. Its major tributaries�including  the Al-Ghazal (Gazelle) River, the Blue Nile, and the Atbara River �join  it before it enters Lake Nasser near the Egypt-Sudan border. Below the  Aswan High Dam, which impounds the lake, it continues northward to its  delta near Cairo, where it empties into the Mediterranean. The first use  of the Nile for irrigation in Egypt began when seeds were sown in the  mud left after its annual floodwaters had subsided. It has supported con�  tinuous human settlement for at least 5,000 years, and networks of canals  and waterworks have been built since the 19th century. The Aswan High  Dam, built in 1959-70, provides flood protection, hydroelectric power,  and a dependable water supply for both crops and humans. The Nile is  also a vital waterway for the transport of people and goods.</p><p>Nilo-Saharan \,nI-lo-s3-'ha-r3n\ languages Group of perhaps 115  African languages spoken by more than 27 million people from Mali to  Ethiopia and from southernmost Egypt to Tanzania. The concept of Nilo-  Saharan as a single stock combining a number of earlier groupings was  introduced in 1963 by Joseph H. Greenberg; most Africanists accepted it  as a working hypothesis, though shifts have taken place. In terms of num�  bers of speakers, the most significant divisions of Nilo-Saharan languages  include Central Sudanic, Fur, Nilotic, Nubian, Saharan, Songhai, and Sur-  mic. Songhai is spoken by more than 2 million people in Mali and Niger,  and Kanuri (a Saharan language) is spoken by about 4.5 million in north�  eastern Nigeria and adjacent Chad and Niger. Central Sudanic comprises  languages of southern Chad, southern Sudan, and northeastern Congo  (Kinshasa). Nubian languages (including the only Nilo-Saharan language  with an ancient written tradition) are spoken along the Nile in northern  Sudan and southern Egypt. The Nilotic languages are spoken by some 14  million people (see Nilotes), including the Dinka, Nuer, Luo, Turkana,  Kalenjin, and Masai.</p><p>Nilot plural Nilotes Any member of a cluster of east-central African  peoples living in southern Sudan, northern Uganda, and western Kenya.  The name refers to the region of the Upper Nile and its tributaries, where  most of them live. Nilotic languages belong to the Eastern Sudanic group  of the Nilo-Saharan family. A notable shared physical characteristic is  their average height, men commonly reaching 7 ft (210 cm). The Acholi,  Dinka, Luo, Masai, Nandi, Nuer, and Shilluk are classed as Nilotes. Alto�  gether they number about seven million.</p><p>Nilsson, Birgit orig. Marta Birgit Svensson (b. May 17, 1918,  Vastra Karup, Swed.�d. Dec. 25, 2005, Vastra Karup) Swedish soprano.

Little is known of his  life except that he was a Brahman and a notable astronomer. Like  Ramanuja, he believed that the creator god and the souls he created were  distinct but shared in the same substance, and he stressed devotion to  Krishna as the only means of liberation from the cycle of rebirth. The  Nimanda sect flourished in the 13th-14th century in eastern India.</p><p>Nimeiri \n3-'mer-e\, Gaafar Mohamed el- (b. Jan. 1, 1930, Wad  Nubawi, Omdurman, Sudan) President of The Sudan (1971-85). In 1969  he helped overthrow the civilian regime of Isma'Il al-Azharl. Nimeiri�s  own government was temporarily ousted in 1971, but he was returned to  office following a plebiscite. He granted autonomy to the Southern Sudan  in 1972, inaugurated one of the world�s largest sugar-refinery projects  (1981), and sought to develop agriculture. His attempts to impose Islamic  law were resisted by Christians and others in the south, which led to his  fall from power.</p><p>NTmes Vnem\ ancient Nemausus  ern France. It was the capital of a  Gaulish tribe that submitted to Rome  in 121 bc. Augustus founded a new  city there, and for five centuries it  was one of the principal cities of  Roman Gaul. It was plundered by the  Vandals and Visigoths in the 5th cen�  tury ad and occupied by Moors in  the 8th century. It passed to the  French crown in 1229. Damaged in  1815 during fighting between royal�  ists and Bonapartists, it returned to  prosperity with the coming of the  railways in the late 19th century. It is  noted for its Roman remains, includ�  ing an amphitheatre, an aqueduct,  and the Maison Caree (an ancient  temple restored in 1789).</p><p>Nimitz Vni-mitsV Chester W(illiam) (b.

He graduated from the U.S. Naval Academy in 1905 and  served in World War I with the U.S. Atlantic submarine force. He rose to  become chief of the navy�s bureau of navigation in 1939. After the Japa�  nese attack on Pearl Harbor, he was made commander in chief of the U.S.  Pacific fleet, which won the battles of Midway and the Coral Sea (1942).  In succeeding years, the historic battles of the Solomon Islands (1942-  43), the Gilbert Islands (1943), and Iwo Jima and Okinawa (1945) were  fought under his direction. The Japanese surrender was signed aboard his  flagship, the USS Missouri. From 1945 to 1947 he served as chief of naval  operations.</p><p>Nimrud See Calah</p><p>Nin Vnen, �ninV, AnaVs (b.

Daughter of the  Cuban composer Joaquin Nin (1878-1949), she began her literary career  in Paris in 1932. In the 1940s she moved to New York, where she pub�  lished novels and short stories at her own expense. Her writing, includ�  ing the novel Cities of the Interior, 5 vol. (1959), shows the influence of  Surrealism and psychoanalysis. She won late recognition in 1966 with the  publication of the first volume of her personal diaries; seven more vol�  umes followed. Her account of her long incestuous relationship with her  father was published posthumously.</p><p>Nina, La See La Nina</p><p>9-11 attacks See September 11 attacks</p><p>Ninety-five Theses Propositions for debate on the question of indul�  gences, written by Martin Luther and, according to legend, posted on the  door of the castle church in Wittenberg, Ger., on Oct. 31, 1517. This event  is now seen as the beginning of the Protestant Reformation. The theses  were written in response to the selling of indulgences to pay for the  rebuilding of St. Peter's Basilica in Rome. They represented an implicit</p><p>criticism of papal policy and stressed the spiritual, inward character of the  Christian faith. Widely circulated, they aroused much controversy. In 1518  Luther published a Latin manuscript with explanations of the theses.</p><p>Nineveh Vni-no-vaV Oldest and most populous city of ancient Assyria,  on the eastern bank of the Tigris River opposite modern Mosul, Iraq. Its  greatest development was under Sennacherib and Ashurbanipal in the 7th  century bc. It was captured and destroyed by Nabopolassar of Babylonia  and his allies, the Scythians and Medes, in 612 bc. Excavations made in  1845-51 revealed palaces, a library, city walls, and many gates and build�  ings.</p><p>Ningxia or Ningsia Vniq-'shya\ in full Hui Autonomous Region  of Ningxia Autonomous region (pop., 2002 est.: 5,720,000), northern  China. It is bounded by Shaanxi and Gansu provinces and Inner Mongo�  lia autonomous region and has an area of 25,600 sq mi (66,400 sq km).  China�s Great Wall runs along its northeastern boundary. The capital is  Yinchuan. It is nearly coextensive with the ancient kingdom of the Tan-  gut people, whose capital was captured by Genghis Khan in the early 13th  century. The region is mostly desert and is sparsely settled, but the vast  plain of the Huang He (Yellow River) in the north has been irrigated for  centuries; over the years many canals have been built.</p><p>Ninhursag \nin-'kur-,sag\ In Mesopotamian religion, the city goddess of  Adab and of Kish. Worshiped especially by the herders of northern Meso�  potamia, she was the goddess of the stony, rocky ground, and she had the  power to produce wildlife in the foothills and in the desert. A mother fig�  ure, she was the goddess of birth; she also appeared as a sorrowing mother  in her lament for her son, a young colt. Her husband was the god Shul-  pae, and among their children was Mululil, a dying god whose death was  mourned in yearly rites.</p><p>Nino, El See El Nino</p><p>Ninsun \'nin-,sun\ In Mesopotamian religion, the city goddess of Kullab.  Worshiped especially by herders in southern Mesopotamia, she was origi�  nally represented as a cow and was considered to be the divine power  behind all the qualities that herders wanted in their cattle. She was also  represented in human form and could give birth to human offspring. Her  son was the wild bull Dumuzi, whom she lamented in a yearly ritual, and  her husband was the legendary hero Lugalbanda. Her Sumerian counter�  parts included Ninhursag.</p><p>Ninurta \ni-'nur-ta\ In Mesopotamian religion, the city god of Girsu. The  son of Enlil and Ninlil, he was the god of thunder and of the spring rains  and floods as well as the god of the plow. His original name was Imdu-  gud (�Raincloud�), and his earliest form was that of the thundercloud rep�  resented as an enormous black bird roaring its thunder cry from a lion�s  head. Eventually Ninurta was given human form, and his original shape  was assigned to his ancient enemy. His festival marked the beginning of  the plowing season.</p><p>Niobe \nI-'o-be\ In Greek mythology, the prototype of the bereaved  mother. The daughter of Tantalus, she married King Amphion of Thebes  and bore him six sons and six daughters. She made the mistake of boast�  ing of her fertility to the Titaness Leto, who had only two children, Apollo  and Artemis. As punishment for her pride, Apollo killed all of Niobe� s sons  and Artemis all her daughters. Niobe was so overwhelmed with grief that  the gods turned her into a rock on  Mount Sipylus (near modern Izmir,</p><p>Turkey), which weeps endlessly as  the snow above it melts.</p><p>Niobid \nI-'o-bid\ Painter (fl. c.</p><p>475-450 bc, Greece) Greek vase  painter, named for a calyx krater  showing the death of the children of  Niobe.

A common laboratory reagent,  it is important in the manufacture of fertilizers and explosives (including  nitroglycerin), as well as in organic syntheses, metallurgy, ore flotation,  and reprocessing of spent nuclear fuel. A strong acid, it is toxic and can  cause severe bums. It attacks most metals and is used for etching steel  and photoengraving.</p><p>nitric oxide Colourless, toxic gas (NO), formed from nitrogen and  oxygen by the action of electric sparks or high temperatures or, more con�  veniently, by the action of dilute nitric acid on copper or mercury. First  prepared c. 1620 by Jan B. Helmont, it was first studied in 1772 by Joseph  Priestley, who called it �nitrous air.� An industrial procedure for the manu�  facture of hydroxylamine is based on the reaction of nitric oxide with  hydrogen in the presence of a catalyst. The formation of nitric oxide from  nitric acid and mercury is applied in a volumetric method of analysis for  nitric acid or its salts. The gas is synthesized via ENZYME-catalyzed reac�  tions in humans and other animals, where it serves as a signaling mol�  ecule. Among its numerous biological roles, it causes dilation of blood  vessels and as such is an important regulator of blood pressure. Nitric oxide  is one of the components of air pollution generated by internal-combustion  ENGINES.</p><p>nitrifying bacteria Vnl-tro-.fi-iqN Small group of oxygen-requiring  bacteria that use nitrogen as an energy source. These microorganisms are  important in the nitrogen cycle as converters of soil ammonia to nitrates,  compounds usable by plants. The nitrification process requires two dis�  tinct groups: bacteria that convert ammonia to nitrites, and bacteria that  convert nitrites to nitrates. In agriculture, irrigation with dilute solutions  of ammonia results in an increase in soil nitrates through the action of  nitrifying bacteria. See also denitrifying bacteria.</p><p>nitrite Vnl-.trfiA Any salt or ester of nitrous acid (HN0 2 ). The salts are  inorganic compounds with ionic bonds, containing the nitrite ion (N0 2 )  and any cation. The esters are organic compounds with covalent bonds,  having the structure R�O�N�O, in which R represents a carbon-  containing combining group and the bonding is from carbon to oxygen.  These covalent nitrites are constitutional isomers (see isomerism) of the nitro  compounds, nitric acid derivatives (R�N0 2 ), in which the bonding is from  carbon to nitrogen. Nitrites are used as food preservatives and color  enhancers, though they are so toxic they have caused deaths and combine  with amines to produce carcinogens. They are used in medicine to dilate  blood vessels.</p><p>nitro compound Vnl-.trcA Any of a class of chemical compounds in  which the nitro group (�N0 2 ) forms part of the molecular structure. The  most common examples are organic compounds, isomers of nitrite esters  in which a carbon atom is linked by a covalent bond to the nitro group�s  nitrogen atom. Many nitro compounds are commercially used as explo�  sives, solvents, or raw materials and chemical intermediates. They are  generally made by a reaction between nitric acid and an organic compound.</p><p>nitrogen Gaseous chemical element, chemical symbol N, atomic num�  ber 7. A colourless, odourless, tasteless gas, it makes up 78% of Earth�s  atmosphere and is a constituent of all living matter. As the nearly unre-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>nitrogen cycle &#x25BA; Nizhny Novgorod I 1367</p><p>active diatomic molecule N 2 , it is useful as an inert atmosphere or to dilute  other gases. Nitrogen is commercially produced by distillation of liquefied  air. Nitrogen fixation, achieved naturally by soil microbes and industrially  by the Haber-Bosch process, converts it to water-soluble compounds  (including ammonia and nitrates). Industrially, ammonia is the starting  material for most other nitrogen compounds (especially nitrates and  nitrites), whose main uses are in agricultural fertilizers and explosives. In  compounds, nitrogen usually has valence 3 or 5. It forms several oxides  including nitrous oxide (N 2 0; laughing gas), nitric oxide (NO), nitrogen  dioxide (N0 2 ), and other forms (such as N 2 0 3 and N 2 0 5 ). Some of the  nitrogen oxides, often referred to generically as NO A , are notorious as  contributors to urban air pollution. Other compounds include the nitrides,  exceptionally hard materials made from nitrogen and a metal; cyanides;  azides, used in detonators and percussion caps; and thousands of organic  compounds containing nitrogen in functional groups or in a linear or ring  structure (see heterocyclic compound). See also nitrogen cycle.</p><p>nitrogen cycle Circulation of nitrogen in various forms throughout  nature. Nitrogen is essential to life, but in the atmosphere it is in a form  (the diatomic molecule N 2 ) unavailable to most organisms. Nitrogen fixa�  tion by microbes turns this nitrogen into nitrates and other compounds,  which plants or algae assimilate into their tissues. Animals that eat plants  in turn incorporate the compounds into their own tissues. Microbes  decompose the remains and waste of all living things into ammonia  (ammonification); the ammonia may leave the soil through vaporization  into the air or leaching into water. Ammonia remaining in soil may be  transformed by bacteria into nitrates (nitrification), which then can be  reassimilated into living organisms, or into free nitrogen (denitrification),  which reenters the atmosphere. Hence, once fixed from air, some nitro�  gen goes through the cycle repeatedly without returning to the gaseous  state.</p><p>nitrogen fixation Any natural or industrial process that causes free  nitrogen in the air to combine chemically with other elements to form  more reactive nitrogen compounds such as ammonia, nitrates, or nitrites.  Soil microorganisms (e.g., Rhizobium bacteria living in root nodules of  legumes) are responsible for more than 90% of all nitrogen fixation.  Though nitrogen is part of all proteins and essential in both plant and ani�  mal metabolism, plants and animals cannot use elemental nitrogen such as  the nitrogen gas (N 2 ) that forms 80% of the atmosphere. Symbiotic  nitrogen-fixing bacteria invade the root hairs of host plants, where they  multiply and stimulate the formation of root nodules, enlargements of  plant cells and bacteria in close association. Within the nodules the bac�  teria convert free nitrogen to nitrates, which the host plant uses for its  development. Nitrogen fixation by bacteria associated with legumes is of  prime importance in agriculture. Before the use of synthetic fertilizers in  the industrial countries, usable nitrogen was supplied as manure and by  crop rotation that included a legume crop.</p><p>nitrogen narcosis or nitrogen euphoria or raptures of the  deep Effects of breathing nitrogen under increased pressure. In divers  breathing compressed air, nitrogen saturates the nervous system, causing  an intoxicating light-headed, numb feeling, then slowed reasoning and  dexterity, and then emotional instability and irrationality. Severe cases  progress to convulsions and blackout. Susceptibility varies, and severity  increases with depth, but there are no aftereffects. Physical function  remains normal, and divers may be unaware of the growing irrationality  that can cause them to rise too fast (see decompression sickness) or let their  air supply run out. Helium, which dissolves less easily in body tissues, is  substituted for nitrogen for deep dives.</p><p>nitroglycerin \ 1 nI-tro- , gli-s9-r9n\ or glyceryl trinitrate Organic  compound, powerful explosive and ingredient of most forms of dynamite.  It is a colourless, oily, somewhat toxic liquid with a sweet, burning taste.  Its safe use as a blasting explosive became possible after Alfred P. Nobel  developed dynamite in the 1860s with an inert porous material (modera�  tor) such as charcoal or diatomaceous earth. Nitroglycerin is also used in  a mixture in rocket propellants. In medicine, it is used to dilate blood ves�  sels, especially to ease angina pectoris.</p><p>nitrous oxide Vnl-tr9s\ or laughing gas Inorganic compound, one  of the oxides of nitrogen. A colourless gas with a pleasantly sweetish odour  and taste, it has an analgesic effect when inhaled; it is used as an anes�  thetic (often called just �gas�) in dentistry and surgery. This effect is pre�  ceded by mild hysteria, sometimes with laughter, hence the name laughing  gas. It is also used as a propellant in food aerosols and as a leak detector.</p><p>Nivernais \,ne-v3r-'na\ Historical region, central France. Originally  part of Burgundy, it became a county c. 10th century. Francis I of France  made it a duchy in 1539 for Francis of Cleves. In 1659 it was sold to  Cardinal Mazarin. His descendants possessed it until the French Revolu�  tion, when it was the last great fief to be reunited to the French crown.  During the ancien regime it was administered from Nevers.</p><p>Nixon, Richard M(ilhous) (b. Jan. 9, 1913, Yorba Linda, Calif.,  U.S.�d. April 22,1994, New York, N. Y.) 37th president of the U.S. (1969�  74). He studied law at Duke University and practiced in California (1937-  42). After serving in World War II, he was elected to the U.S. House of  Representatives (1946). As a member of the House Un-American Activi�  ties Committee, he received national attention for his hostile questioning of  Alger Hiss. In 1950 he was elected to the Senate following a bitter campaign  in which he unfairly portrayed his opponent as a communist sympathizer;  the epithet �Tricky Dick� dates from this period. He won the vice presi�  dency in 1952 as the running mate of Republican Dwight D. Eisenhower.  During the campaign he delivered a nationally televised address, the  �Checkers� speech (named for the dog he admitted receiving as a political  gift), to rebut charges of financial misconduct. He and Eisenhower were  reelected easily in 1956. As the Republican presidential candidate in 1960,  he lost narrowly to John F. Kennedy. After failing to win the 1962 California  gubernatorial race, he announced his retirement from politics and criticized  the press, declaring that it would not �have Dick Nixon to kick around any�  more.� He moved to New York to practice law. He reentered politics by  running for president in 1968, narrowly defeating Hubert H. Humphrey with  his �southern strategy� of seeking votes from southern and western con�  servatives in both parties. As president, he began to withdraw U.S. military  forces from South Vietnam while resuming the bombing of North Vietnam.  His expansion of the Vietnam War to Cambodia and Laos in 1970 provoked  widespread protests in the U.S. He established direct relations with China  and made a state visit there in 1972, the first by a U.S. president. On a visit  to the Soviet Union later that year, he signed agreements resulting from the  Strategic Arms Limitation Talks between the U.S. and the Soviet Union held  between 1969 and 1972, known as SALT I. In domestic affairs, Nixon  responded to persistent inflation and increasing unemployment by devalu�  ing the dollar and imposing unprecedented peacetime controls on wages  and prices. His administration increased funding for many federal civil-  rights agencies and proposed legislation that created the Occupational  Safety and Health Administration (OSHA) and the Environmental Protec�  tion Agency (EPA). In 1972 he won reelection with a landslide victory over  George McGovern. Assisted by Henry A. Kissinger, he concluded a peace  agreement with North Vietnam (1973), though the war did not come to an  end until 1975. His administration helped to undermine the coalition gov�  ernment of Chile�s Marxist Pres. Salvador Allende, leading to Allende�s  overthrow in a military coup in 1973. Nixon�s second term was overshad�  owed by the Watergate scandal, which stemmed from illegal activities by  Nixon and others related to the burglary and wiretapping of the headquar�  ters of the Democratic Party. After lengthy congressional investigations  and facing near-certain impeachment, Nixon resigned the presidency on  Aug. 8,1974, the first president to do so. Though never convicted of wrong�  doing, he was pardoned by his successor, Gerald Ford. In retirement, he  wrote his memoirs and several books on foreign policy, which modestly  rehabilitated his reputation and earned him a role as an elder statesman and  foreign-policy expert.</p><p>Nizam al-Mulk \ne-'zam-ul- , mulk\ orig.

He worked for the rulers of the  Ghaznavid dynasty before serving Alp-Arslan as governor of Khorasan. In  1063 he was made vizier, a position he occupied for 30 years, serving  Alp-Arslan�s son Malik-Shah from the latter�s ascension. Believing that  a ruler�s power should be absolute and that the ruler should preserve the  kingdom�s stability and traditions, he recorded his views in the Seyasat-  nameh (�Book of Government�). He is seen as the quintessential vizier  and as a staunch Sunnite Muslim. He promoted the madrasah as a centre  of learning, partly to combat ShTite propaganda. He was murdered, likely  by an Isma'Ili Assassin, after falling out of favour with Malik-Shah.</p><p>Nizam?

His aid was invoked in seafaring and hunting, and he was the god  of prosperity. He was the father of Freyr and Freyja by his sister. Njord�s  tribe, the Vanir, gave him as a hostage to the rival tribe of Aesir, and the  giantess Skadi chose him as her husband. The marriage failed because  Njord preferred to live in Noatun, his home by the sea, whereas Skadi  was happier in her father�s mountain dwelling place.

Nkomo helped lead the guerrilla war against white rule in Rhodesia, but  his forces played a less important role than those of Robert Mugabe. As  leader of the Zimbabwe African People�s Union (ZAPU), he became  Mugabe�s longtime rival. They participated in a coalition government in  1980-82, but Nkomo was removed following a breach between them.  ZAPU and Mugabe�s Zimbabwe African National Union (ZANU) merged  in 1987 to form ZANU-Patriotic Front, and Nkomo became a vice presi�  dent in Mugabe�s government in 1990.</p><p>Nkrumah Ven-'krii-moV Kwame (b. September 1909, Nkroful, Gold  Coast�d. April 27, 1972, Bucharest,</p><p>Rom.) Nationalist leader and presi�  dent of Ghana (1960-66). Nkrumah  worked as a teacher before going to  the U.S. to study literature and  socialism (1935-45). In 1949 he  formed the Convention People�s  Party, which advocated nonviolent  protests, strikes, and noncooperation  with the British authorities. Elected  prime minister of the Gold Coast  (1952-60) and then president of  independent Ghana, Nkrumah  advanced a policy of Africanization  and built new roads, schools, and  health facilities. After 1960 he  devoted much of his time to the Pan-  African movement, at the expense of  Ghana�s economy. Following an  attempted coup in 1962, he increased  authoritarian controls, withdrew  from public life, increased contacts  with communist countries, and wrote works on political philosophy. With  the country facing economic ruin, he was deposed in 1966 while visiting  Beijing.</p><p>no-till farming or till-less agriculture Cultivation technique in  which the soil is disturbed only along the slit or hole into which seeds are  planted. Reserved detritus from previous crops covers and protects the  seedbed. Primary benefits are a decreased rate of soil erosion; reduced  need for equipment, fuel, and fertilizer; and significantly less time  required for tending crops. The method also improves soil-aggregate for�  mation, microbial activity in the soil, and water infiltration and storage.  Conventional tillage controls weed growth by plowing and cultivating,  but no-till farming selectively uses herbicides to kill weeds and the remains  of the previous crop. No-till farming is one of several primitive farming  methods revived as conservation measures in the 20th century.</p><p>Noah Biblical character from Genesis. The son of Lamech and ninth in  descent from Adam, he was a man of blameless piety, who was chosen by  God to perpetuate the human race after his wicked contemporaries had per�  ished in the flood. On God�s instructions, Noah built an ark and took into  it one male and one female of each of the world�s animals. After the waters  receded, God set a rainbow in the sky as a guarantee of his promise never  again to curse the earth. Noah was the father of Shem, Ham, and Japheth,  from whom the entire human race is supposed to have descended. Noah is  also said to have been the originator of vineyard cultivation.</p><p>noaide \no-'I-de\ In Sami religion, a shaman who mediates between his  clients and various supernatural beings and forces. To aid people suffer�  ing from illness or other serious troubles, the noaide performs a dramatic  seance, which includes divination, trance, confrontation of supernatural  beings, and the ritual treatment of the patient. The noaides can accom�  plish both good and evil, and their powers were formerly much feared.</p><p>Nobel \,no-'bel\, Alfred (Bernhard) (b. Oct. 21, 1833, Stockholm,  Swed.�d. Dec. 10, 1896, San Remo, Italy) Swedish chemist, engineer,  and industrialist. His attempts to find a safe way to handle nitroglycerin  resulted in the invention of dynamite and the blasting cap. He built a net�  work of factories to manufacture dynamite and corporations to produce  and market his explosives. He went on to develop more powerful explo�  sives and to construct and perfect detonators for explosives that did not  explode on simple firing (e.g., when lit with a match). Nobel registered  more than 350 patents, many unrelated to explosives (e.g., artificial silk  and leather). A complex personality, both dynamic and reclusive, he was  a pacifist but was labeled the �merchant of death� for inventing explo�  sives used in war. Perhaps to counter this label, he left most of his  immense fortune, from worldwide explosives and oil interests, to estab�  lish the Nobel Prizes, which would become the most highly regarded of  all international awards.</p><p>Nobel Prize Any of the prizes awarded annually by four institutions  (three Swedish and one Norwegian) from a fund established under the  will of Alfred B. Nobel. The will specified that awards should be given �to  those who, during the preceding year, shall have conferred the greatest  benefit on mankind.� Since 1901, prizes have been awarded for physics,  chemistry, physiology or medicine, literature, and peace; since 1969, a  sixth prize, established by the Bank of Sweden, has been awarded in eco�  nomic sciences. The Nobel Prizes are regarded as the most prestigious  prizes in the world. See tables on opposite and following pages.</p><p>noble gas or inert gas Any of the six chemical elements that make  up the rightmost group of the periodic table as usually arranged: helium,  neon, argon, krypton, xenon, and radon. All are colourless, odourless, and  nonflammable and occur in tiny amounts in the atmosphere (though  helium is the most plentiful element in the universe). Their stable elec�  tronic configurations, with no unpaired electrons to share, make them  extremely unreactive�hence �noble� (i.e., aloof) or inert�though the  three heaviest, with outer electrons held less firmly, can form compounds  (mainly with fluorine). These gases absorb and give off electromagnetic  radiation in a much less complex way than other substances, a property  exploited in their use in fluorescent lighting devices and discharge lamps.  They glow with a characteristic colour when confined in a transparent  container at low pressure with an electric current passing through it. Their  very low boiling and melting points make them useful as refrigerants for  low-temperature research (see cryogenics).</p><p>nocturne Nineteenth-century character piece for piano. The name was  first used c. 1812 by the Scottish composer John Field (1782-1837) for  works employing a lyrical melody over an accompaniment of broken  chords.

He served as governor of Taiwan and fought in  the Russo-Japanese War. On the death of the  Meiji emperor, Nogi and his wife committed  ritual suicide by seppuku (self-disembowlment),  considered the ultimate samurai act of loyalty.  This action affected such Meiji-period writers  as Natsume Soseki and Mori Ogai (1862-1922)  and illuminated the contrast between Japan�s  feudal past and rapidly modernizing present.</p><p>Noguchi \no-'gu-che\, Isamu (b. Nov. 17,  1904, Los Angeles, Calif., U.S.�d. Dec. 30,  1988, New York, N.Y.) U.S. sculptor and  designer. He spent his early years in Japan.  After premedical studies at Columbia Univer�  sity, he became Constantin Brancusi�s assistant  in Paris. He was influenced as well by Alberto  Giacometti, Alexander Calder, Pablo Picasso, and  Joan Miro. His medical training suggested to  him the interrelatedness of bone and stone.  Much of his work consists of elegantly  abstracted, rounded forms in highly polished  stone. His long collaboration with Martha Gra�  ham resulted in stage sets for many ballets, and  he also designed many public sculptures, sculp�  tural gardens, and playgrounds, as well as fur�  niture.</p><p>Noh theatre or No theatre Classic Japa�  nese theatrical form. One of the world�s oldest  extant theatrical forms, Noh theatre has a heroic  theme, a chorus, and highly stylized action, cos�  tuming, and scenery. Its all-male performers are  storytellers who use their visual appearances  and movements to suggest their tale rather than  enact it. Noh (from Japanese no, meaning �tal�  ent� or �skill�) developed from ancient forms  of dance-drama and became a distinctive form  in the 14th century. The five types of Noh plays  are the kami (�god�) play, which involves a  sacred story of a Shinto shrine; the shura mono  (�fighting play�), which centres on warriors; the  katsura mono (�wig play�), which has a female  protagonist; the gendai mono (�present-day  play�) or kyojo mono (�madwoman play�),  which is varied in content; and the kiri or  kichiku (�final� or �demon�) play, which fea�  tures devils and strange beasts. Kan�ami (1333�  84) and his son Zeami (1363-1443) wrote many  of the most beautiful Noh texts; more than 200  remain in the modem Noh repertoire.</p><p>noise Undesired sound that is intrinsically  objectionable or that interferes with other  sounds being listened to. In electronics and  information theory, noise refers to those ran�  dom, unpredictable, and undesirable signals, or  changes in signals, that mask the desired infor�  mation content. In radio, this noise is called  static; in television, it is called snow. White  noise is a complex signal or sound covering the  entire range of component frequencies, or  tones, all of which possess equal intensity.</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1374 I Nok culture &#x25BA; nongovernmental organization</p><p>L_</p><p>N</p><p>Nok culture Ancient Iron Age African culture.

Australian artist. Early in his career he created  greatly simplified abstractions. In the mid 1940s he began to paint the  local desolate desert landscapes in a more representational style. In his  mature work he often applied unusual media�such as polyvinyl  acetate�to masonite, glass, or canvas. Apart from his landscapes, most  of his works dealt with Australian historical or legendary characters and  events�notably, the bushranger Ned Kelly.</p><p>Noland, Kenneth (b. April 10, 1924, Asheville, N.C., U.S.) U.S.  painter. Noland attended Black  Mountain College in North Carolina  and studied under the French sculp�  tor Ossip Zadkine in Paris (1948-  49). He and Morris Louis, influenced  by the work of Helen Frankenthaler,  worked together on the technique of  staining with thinned paints. This  method presented pure, saturated  colour as an integral part of the can�  vas. He employed his colours in con�  centric rings and parallels that were  shaped and proportioned in relation  to the shape of the canvas. Noland  taught at the Institute of Contempo�  rary Arts (1950-52) and at Catholic  University (1951-60), both in Wash�  ington, D.C., and at Bennington Col�  lege (1968) in Vermont.</p><p>Nolde Vnol-doX, Emil orig.

Bom to a  peasant family, he carved wood for a living and came late to painting.  Though briefly a member of Die BrOcke (1906-07), he was essentially a  solitary painter. Fervently religious and racked by a sense of sin, he cre�  ated such works as Dance Around the Golden Calf { 1910), in which the  figures� erotic frenzy and demonic faces are rendered with deliberately  crude draftsmanship and dissonant colours. On an ethnological expedi�  tion to the East Indies (1913-14), he was impressed by the power of the  art he saw there. Back in Europe, he produced brooding landscapes (e.g.,  Marsh Landscape, 1916) and colourful flowers. As a printmaker he was  noted especially for the stark black-and-white effect of his crudely incised  woodcuts. Although he was an early advocate of Germany�s National  Socialist Party, the party declared his art �degenerate� and forbade him  to paint. His late, postwar works reveal his disillusionment.</p><p>nomadism Way of life of peoples who do not live continually in the  same place but move cyclically or periodically. It is based on temporary  centres whose stability depends on the available food supply and the  technology for exploiting it. A hunting and gathering society is a type of  nomadic group. Pastoral nomads, who depend on domestic livestock,  migrate in an established territory to find pasture for their animals. Tinker  or trader nomads, such as the Roma (Gypsies; see Rom) and the Irish and  Scottish Travellers, are associated with a larger society but maintain their  mobile way of life. Nomadism declined in the 20th century as urban cen�  tres expanded and governments sought to regulate or eliminate it.</p><p>Nome Seaport (pop., 2000: 3,505), western Alaska, U.S., on the south�  ern side of the Seward Peninsula. Founded as a mining camp called Anvil</p><p>City after the discovery of gold at nearby Anvil Creek in 1898, it became  a centre of the Alaskan gold rush of 1899-1903. Its population, estimated  at 20,000 in 1900, had dwindled to 852 by 1920. Gold mining remained  the chief occupation until the dredge fields were closed in 1962. The fin�  ish line for the Iditarod trail sled race, it also serves as a supply centre for  northwestern Alaska.</p><p>non-Euclidean geometry Any theory of the nature of geometric  space differing from the traditional view held since Euclid�s time. These  geometries arose in the 19th century when several mathematicians work�  ing independently explored the possibility of rejecting Euclid�s parallel  postulate. Different assumptions about how many lines through a point  not on a given line could be parallel to that line resulted in hyperbolic  geometry and eluptic geometry. Mathematicians were forced to abandon the  idea of a single correct geometry; it became their task not to discover  mathematical systems but to create them by selecting consistent axioms  and studying the theorems that could be derived from them. The devel�  opment of these alternative geometries had a profound impact on the  notion of space and paved the way for the theory of relativity. See also  Nikolay Lobachevsky, Bernhard Riemann.</p><p>nonaligned movement In international politics, the group of states  sharing the peacetime policy of avoiding political or economic affiliations  with major power blocs. At its beginning the nonaligned movement con�  sisted primarily of Asian and African states that were once colonies of the  Western powers and were wary of being drawn into a new form of depen�  dence by the West or by the communist bloc. Founded by Jawaharlal  Nehru, Gamal Abdel Nasser, and others, the movement held its first offi�  cial meeting in 1961 in Bandung, Indon.; 25 countries attended. Meetings  have since been held on a three-year schedule. While the Soviet Union  existed, the movement tended to seek development assistance from both  the U.S. and the Soviet Union but to refrain from forming political or  military alliances with either country. Since the dissolution of the Soviet  Union in 1991, the nonaligned movement has been chiefly concerned with  debt forgiveness and with development of fairer trade relationships with  the West. By the early 21st century the movement had more than 110  members.</p><p>noncognitivism Denial of the characteristic cognitivist thesis that  moral sentences are used to express factual statements. Noncognitivists  have proposed various alternative theories of meaning for moral sen�  tences. In Language, Truth and Logic (1936), A. J. Ayer stated the emo-  tivist thesis that moral sentences are not statements at all (see emotivism).  In The Language of Morals (1952), Richard M. Hare (born 1919) agreed  that in making moral judgments we are not primarily seeking to describe  anything, but claimed that neither are we simply expressing our attitudes;  instead, he suggested that moral judgments prescribe�that is, are a form  of imperative sentence (see prescriptivism).</p><p>Nonconformist Any English Protestant who does not conform to the  doctrines or practices of the established Church of England. The term was  first used after the Restoration of the monarchy in 1660 to describe con�  gregations that had separated from the national church. Such congrega�  tions, also called Separatists or Dissenters, often rejected Anglican rites  and doctrines as being too close to Catholicism. In the late 19th century,  Nonconformists of various denominations joined together to form the Free  Church Federal Council. In England and Wales the term is generally  applied to all Protestant denominations outside Anglicanism, including  Baptists, Congregationalists, Unitarians, Presbyterians, Methodists,  Quakers, and Churches of Christ.</p><p>nondirective psychotherapy or client-centered therapy</p><p>Type of psychotherapy in which the counselor refrains from interpretation  or explanation but encourages the client to establish a person-to-person  relationship with him or her and to talk freely. It originated with Carl R.  Rogers and influenced later individual and group therapies. The goal is to  enable the client to see him- or herself more clearly and react more openly  with the therapist and others. The client determines the course, speed, and  duration of treatment.</p><p>nongovernmental organization (NGO) Organization that is not  part of any government. A key distinction is between not-for-profit groups  and for-profit corporations; the vast majority of NGOs are not-for-profit.  In some countries, particularly socialist ones, some NGOs are  government-organized. The purposes of NGOs cover the entire range of  human interests and may be domestic or international in scope. Many  NGOs are key sources of information for governments on issues such as</p><p>man, 1967</p><p>�ARNOLD NEWMAN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Nonni River &#x25BA; Norfolk I 1375</p><p>human rights abuses and environmental degradation.

A law student, he also studied music with Gian  Francesco Malipiero (1882-1973), Bruno Maderna (1920-73), and Her�  mann Scherchen (1891-1966). He came to public attention in 1950 with  his work Variazioni Canoniche, orchestral variations on a 12-tone theme  of Arnold Schoenberg, whose daughter Nuria he married in 1955. An  avowed communist, Nono often produced works of political substance,  many of which sparked controversy and reaction. He employed aleatory  (chance) techniques and SERIAUSM, sometimes fragmenting language and  using electronically manipulated sounds. His best-known work is the  opera Intolleranza (1961).</p><p>nonobjective art See abstract art</p><p>Nonpartisan League Alliance of U.S. farmers to gain protection  from wheat monopolies.

English noble prominent in the reign  of Henry VIII. Son of the 2nd duke of Norfolk, he was made lord high  admiral in 1513 and helped rout the Scots at the Battle of Flodden. Suc�  ceeding his father as duke (1524), he led the faction opposed to Cardinal  Wolsey, whom he replaced as president of the royal council in 1529. He  supported the marriage of his niece Anne Boleyn to Henry (1533), but  later (as lord high steward) he presided over her trial (1536). He skillfully  suppressed the Pilgrimage of Grace rebellion and by 1540 was the most  powerful of Henry�s councillors. His position weakened after his niece  Catherine Howard was put to death (1542) and his son Henry Howard  (1517-47) was executed for treason.

As pagan pirates from  Denmark, Norway, and Iceland, they raided the European coast in the 8th  century. They settled in the lower Seine valley by c. 900. In 911 they were  granted territory around what is now Rouen by King Charles III and then  extended their territory westward. They founded the duchy of Normandy,  governed by a line of rulers who called themselves counts or dukes of Nor�  mandy. Though the Normans converted to Christianity and adopted the  French language, they continued to display their Viking ancestors� reck�  lessness and appetite for conquest. In the 11th century they seized England  in the Norman Conquest and colonized southern Italy and Sicily. The Nor�</p><p>mans also participated in the reconquest of Spain and in the Crusades, and  the Normans of Italy and Sicily were rivals of the Byzantine emperors.</p><p>Norman, Greg(ory John) (b.

An  imposing stage presence with a vibrant and flexible voice, her operatic  and concert repertoire encompasses an exceptionally wide range.</p><p>Norman Conquest (1066) Military conquest of England by William,  duke of Normandy (later William I), mainly through his victory over  Harold II at the Battle of Hastings. Edward the Confessor had designated  William as his successor in 1051. When Harold, duke of Wessex, was  crowned king of England in 1066 instead, William assembled an invasion  force of 5,000 knights. After defeating Harold�s army near Hastings on  October 14 and advancing to London, he was crowned king in Westmin�  ster Abbey on Christmas Day, 1066. Native revolts continued until 1071,  notably in Northumbria. The Norman Conquest brought great social and  political changes to England, linking the country more closely with west�  ern Europe and replacing the old English aristocracy with a Norman aris�  tocracy. The English language was subjected to a long period of influence  by Anglo-French, which remained in literary and courtly use until the  reign of Edward III and in legal reporting until the 17th century.</p><p>Normandy French Normandie \nor-ma n -'de\ Historic and cultural  region, northwestern France. The capital was Rouen. It has been inhabited  since Paleolithic times. Its Celtic population was conquered by the Romans  c. 56 bc, when it became part of the province of Lugdunensis. Invaded by  Vikings in the 8th century ad, it was ceded to their chief, Rollo, in 911 by  Charles III (the Simple) of France. The Vikings became known as Nor�  mans, hence the region�s name. William, duke of Normandy, united Nor�  mandy and England (Norman Conquest, 1066) and became William I (the  Conqueror) of England. Normandy became a province of France in 1450  and was divided into several departments after the French Revolution. It  was the site of the World War II Allied invasion of German-occupied  France in 1944 (see Normandy Campaign). The region has retained its rural  character despite the growth of towns along the lower Seine valley.</p><p>Normandy Campaign Allied invasion of northern Europe in World  War II that began on June 6, 1944, with the largest amphibious landing  in history in Normandy, France. Also called Operation Overlord, the land�  ing transported 156,000 U.S., British, and Canadian troops across the  English Channel in over 5,000 ships and 10,000 planes. Commanded by  Gen. Dwight D. Eisenhower, the Allied forces landed at five beaches on the  Normandy coast and soon established lodgement areas, despite stiff Ger�  man resistance and heavy losses at the code-named Omaha Beach and  Juno Beach. Allied air supremacy prevented rapid German reinforce�  ments, and discord between Adolf Hitler and his generals stalled crucial  counterattacks. Though delayed by heavy fighting near Cherbourg and  around Caen, the Allied ground troops broke out of the beachheads in  mid-July and began a rapid advance across northern France. The Nor�  mandy Campaign is traditionally considered to have concluded with the  liberation of Paris on Aug. 25, 1944.</p><p>Norodom Vnor-o-doirA orig. Vody (b. 1834, Cambodia�d.

After  the death of Norodom�s father in 1860, the Siamese asserted sole dominion  over Cambodia by refusing to allow the Vietnamese to participate in Noro�  dom�s crowning. France opposed Siamese claims on the country and  forced Norodom to accept French protection.

During  the Vietnam War he steered a neutral course between the radical right and  left in both his foreign and internal policies. Overthrown by Lon Nol in  1970, he campaigned for the Khmer Rouge but was imprisoned after they  came to power, and most of his family was killed. Released in the face  of a Vietnamese invasion (1979), he denounced both the Vietnamese and  the Khmer Rouge. In 1982 he became president of a fragile coalition of  resistance groups. Following UN-sponsored elections in 1993, Cambo�  dia�s National Assembly voted to restore the monarchy, and Sihanouk  again became king.

As  prime minister, he gave vacillating support to both harsh and conciliatory  measures toward the American colonies before the American Revolution.  Although only a halfhearted supporter of the war, he was a pliant agent  of George III. He resigned on hearing the news of Charles Cornwallis�s  defeat at the Siege of Yorktown.

The third-largest con�  tinent on earth, it lies mostly between the Arctic Circle and the Tropic of  Cancer. It is almost completely surrounded by bodies of water, including  the Pacific Ocean, the Bering Strait, the Arctic Ocean, the Atlantic Ocean,  and the Caribbean Sea and Gulf of Mexico. Area: 9,361,791 sq mi  (24,247,039 sq km). Population (2001 est.): 454,225,000. Shaped like an  inverted triangle. North America was apparently the first continent to  achieve its current approximate size and shape. Its geologic structure is  built around a stable platform of Precambrian rock called the Canadian  Shield. To the southeast are the Appalachian Mountains and to the west are  the younger and much taller Cordilleras. These mountains extend the  length of the continent and occupy about one-third of the total land area.  The Rocky Mountains constitute the eastern Cordillera. The highest point is  Mount McKinley. The Mississippi River basin, including its major tributaries,  the Missouri and Ohio, occupies more than one-eighth of the continent�s  total area. Generally temperate climatic conditions prevail. Arable land  accounts for about one-eighth of the land area and forests for about one-  third. English, the primary language of the U.S., predominates, followed by  Spanish; French is spoken in parts of Canada. Most of the continent�s popu�  lation of European descent is found in the U.S. and Canada. Intermarriage  between whites and Indians was common in Mexico, and mestizos consti�  tute about three-fifths of the Mexican population. North America has a mix�  ture of developed, partly developed, and developing economies, adequate  reserves of most metallic resources, and the world�s largest reserves of cad�  mium, copper, lead, molybdenum, silver, and zinc. It is the world�s leading  food producer, largely because of mechanized and scientific farming in the  U.S. and Canada. Among the continent�s democratically governed states  are Canada, Mexico, Costa Rica, and the U.S. The nations of North  America have sought hemispheric unity as members of the Organization of  American States, which also includes South American countries. They also  sought stronger economic ties, and in 1992 Canada, the U.S., and Mexico  signed the North American Free Trade Agreement (NAFTA), which called for  the elimination of most tariffs and other trade barriers between the three  countries. The first inhabitants were American Indians, who migrated from  Asia about 20,000 years ago. The greatest pre-Columbian civilizations  were in Mesoamerica (see Mesoamerican civilization) and included the  Olmec, Maya, Toltec, and Aztec, who were conquered by the Spanish. The  continent long remained sparsely settled and undeveloped. Beginning in  the 17th century it underwent a profound transformation with the coming  of Europeans and the Africans they introduced as slaves. The style of life  became Latin American south of the Rio Grande and Anglo-American to  the north, with enclaves of French culture in Canada and Louisiana. Sla�  very, practiced in the 16th-19th centuries, added a significant minority cul�  ture of African origin, especially in the U.S. and the Caribbean (see West  Indies). The huge industrial economy of the U.S., its abundant resources,  and its military strength give the continent considerable global influence.

Several Indian peoples inhabited the area before Europeans  arrived. The coast was explored by Giovanni da Verrazzano in 1524, and  the first English settlement in the New World was established at Roanoke  Island in 1585. It formed part of the Carolina grant of 1663. A provincial  congress in 1776 gave the first explicit sanction of independence by an  American colony, and North Carolina was invaded by British troops in  1780.

The Ross  Lake National Recreation Area separates the park into two sections, the  northern unit extending to the Canadian border and the southern unit  adjoining the Lake Chelan National Recreation Area.</p><p>North Dakota State (pop., 2000: 642,200), U.S. Situated in the north-  central region, it is bordered by Canada and the U.S. states of Minnesota,  South Dakota, and Montana. It covers 70,704 sq mi (183,123 sq km); its  capital is Bismarck. The Missouri River crosses it; the Red River forms its  eastern boundary. There is evidence of prehistoric inhabitation through�  out the state. At the time of European contact, it was inhabited by vari�  ous tribes of Plains Indians. It became part of the U.S. with the Louisiana  Purchase of 1803. The northeastern corner was added by a treaty with  Great Britain in 1818. In 1804-05 the Lewis and Clark Expedition wintered  there among the Indians. In 1861 it became part of the Dakota Territory.  Separated from South Dakota, it was admitted to the Union in 1889 as  the 39th state. In the 20th century North Dakota�s history was marked by  the increasing mechanization of agriculture, the enlargement of farms, and  the loss of a rural population. In the 1950s it became an oil-producing  state, and in the 1960s air bases and missile sites were built there. Its larger  cities include Fargo, Grand Forks, and Minot.</p><p>Theodore Roosevelt National Park, North Dakota, U.S.</p><p>�ANNIE GRIFFITHS BELT</p><p>North Down District (pop., 2001: 76,323), eastern Northern Ireland.  Located on the southern shores of Belfast Lough, it was established in  1973, with Bangor as its administrative seat. Most of the working popu�  lation is employed in Belfast. Tourism flourishes, and Bangor is a popu�  lar seaside resort.</p><p>North German Confederation (1867-71) Union of the German  states north of the Main River, formed after Prussia�s victory in the Seven  Weeks' War. The confederation recognized the individual states� rights  but was effectively controlled by Prussia, whose king served as its presi�  dent and whose chancellor was Otto von Bismarck. Its constitution served  as a model for that of the German Empire, with which it merged in 1871.</p><p>North Island Island (pop., 2001 est.: 2,849,724), New Zealand. The  smaller of the country�s two principal islands, it is separated from South  Island by the Cook Strait. It has an area of 44,702 sq mi (115,777 sq km).  A growing majority of the population of New Zealand lives on North  Island, concentrated in the cities of Wellington and Auckland.</p><p>North Korea See North Korea</p><p>North Platte River River, Colorado, Wyoming, and Nebraska, U.S.  One of the two main arms of the Platte River, it rises in northern Colo�  rado, flows north into Wyoming, then turns east and southeast across the  Nebraska border to join the South Platte and form the Platte. It is 680 mi  (1,094 km) long and is part of an irrigation, power, and flood-control  project of the Missouri River basin. It has large reservoirs and dams.</p><p>North Pole Northern end of the Earth�s geographic axis, located at lati�  tude 90� N. It is the northern point from which all meridians of longitude  start. Lying in the Arctic Ocean and covered with drifting pack ice, it has  six months of constant sunlight and six months of total darkness each year.  Robert E. Peary claimed to have reached the pole by dogsled in 1909, but  that is now in dispute; Roald Amundsen and Richard E. Byrd claimed to  have reached it by air in 1926. The geographic pole does not coincide  with the magnetic North Pole, which in the early 21st century lay at about  82�45' N, 114�25' W, or with the geomagnetic North Pole, which is at  about 79�45'N, 71 �45'W.</p><p>North Sea ancient Mare Germanicum Arm of the Atlantic Ocean.  Extending south from the Norwegian Sea between Norway and the Brit�  ish Isles, it connects the Skagerrak (channel between Norway and Den�  mark) with the English Channel. It is about 600 mi (970 km) long and 350  mi (560 km) wide, with an average depth of 308 ft (94 m). Parts of the  sea feature deep trenches, while others have excellent fishing, renowned  fisheries, and extensive oil and natural gas deposits.</p><p>North Star See Polaris</p><p>North West Co. (1783 -1821) British-Canadian fur-trading company.  Its operations were centred around the Lake Superior region and the val�  leys of the Red, Assiniboine, and Saskatchewan rivers. It later spread  north and west to the Arctic and Pacific oceans. When its competitor, the  Hudson's Bay Co., established a colony on the Red River (1811-12), North  West workers destroyed the colony in the Seven Oaks Massacre. Hudson�s  Bay workers retaliated by destroying the North West post at Fort Gibral�  tar. The British government pressured the two companies to merge in 1821  as the Hudson�s Bay Co.</p><p>North York Former city (pop., 2001: 608,288), southeastern Ontario,  Canada. In 1998 it joined the cities of Etobicoke, Scarborough, Toronto,  and York and the borough of East York to become the City of Toronto.  North York became a borough in 1967 and a city in 1979. Planned indus�  trial and residential development protects more than 4,000 acres (1,620  hectares) of parks and open space. York University and the Black Creek  Pioneer Village are among its attractions.</p><p>North Yorkshire Administrative (pop., 2001: 569,660) and geo�  graphic county, part of the historic county of Yorkshire, northern England.  Its administrative seat is Northallerton. Prehistoric sites show evidence of  a military Roman occupation. In the Middle Ages it was a peripheral  region of England with numerous castles of the great landowning fami�  lies. Monastic orders, including the Cistercians, grew wealthy from sheep  farming. The area played a significant part in the Wars of the Roses and  the English Civil Wars. The modem economy is mainly agricultural.</p><p>Northampton Town and borough (pop., 2001: 194,477), administra�  tive and historic county of Northamptonshire, in the Midlands region,  England. Originating c. 1100 as a walled town with a castle, it was granted  its first charter in 1189. In 1460, during the Wars of the Roses, King Henry  VI was captured in Northampton by Yorkists. The town walls survived  until the Restoration, when they were torn down under King Charles II as  punishment for supporting the Parliamentarians. Now a retail and mar�  keting centre, it also supports light industry.</p><p>Northampton, Henry Howard, earl of (b. Feb. 25, 1540, Shot-  tesham, Norfolk, Eng.�d. June 15, 1614, London) English noble noted  for his intrigues in the reigns of Elizabeth I and James I. Younger brother of  the 4th duke of Norfolk, he was implicated in efforts to free Mary, Queen  of Scots. He successfully sought favour with the Scottish king James VI,  who, on his accession as James I of England, made Howard a privy coun�  cillor (1603) and earl of Northampton (1604). As a judge at the trials of  Walter Raleigh (1603) and Guy Fawkes (1605), he pressed for conviction.</p><p>Northamptonshire Xnor-'thamp-ton-.shhA Administrative (pop.,  2001: 629,676) and historic county of the East Midlands region, England.

July 15, 1865, Chapelizod, near Dublin, Ire.�d.  Aug. 14, 1922, London, Eng.) British newspaper publisher. After an  impoverished childhood and a few attempts to make a quick fortune, he  joined his brother, Harold Sidney Harmsworth (1868-1940), in publish�  ing popular periodicals that formed the basis of Amalgamated Press, at  the time the world�s largest periodical publishing empire. In 1896 he  started the Daily Mail, one of the first British newspapers to popularize  its coverage to appeal to a mass readership. He also founded the Daily  Mirror (1903) and bought The Times (1908), transforming it into a mod�  ern newspaper. His influence was greatest in shifting the press away from  its traditional informative role to that of the commercial exploiter and  entertainer of mass publics. He has been considered the most successful  publisher in the history of the British press.</p><p>Northeast Passage Maritime route along the northern coast of  Europe and Asia. It lies between the Atlantic and Pacific oceans mainly  off northern Siberia. Early explorers included Willem Barents, Olivier  Brunei, and Henry Hudson. In 1778 Capt. James Cook saw both sides of  the Bering Strait and demonstrated that Asia and North America are two  separate continents. The passage was first traversed by Adolf Erik Nor-  denskiold in 1878-79. Since the late 1960s it has been kept open in sum�  mer by icebreakers.</p><p>Northern Dvina \dve-'na\ River Russian Severnaya Vsye-  vyir-n9-yo\ Dvina River, northern Russia. Formed by the junction of the  Sukhona and Yug rivers, it is one of the largest and most important water�  ways of the northern European part of Russia. It flows northwest for 462  mi (744 km) and enters the Dvina inlet of the White Sea below the city  of Arkhangelsk. Navigable for most of its length, it was used by early fur  hunters and colonists, and monasteries and towns were established at  important confluences. It retains its economic importance and is linked  with the Volga-Baltic Waterway via the Sukhona River.</p><p>Northern Expedition (1926-27) Campaign of the Chinese Nation�  alist army, led by Chiang Kai-Shek, that advanced north from Guangzhou  (Canton) to the Yangtze River (Chang Jiang) battling warlord forces. The  Northern Expedition was aided by Soviet arms and advisers and by a pro�  paganda corps that preceded them. After defeating the warlords, the  Nationalist army turned on Britain as the chief imperialist power and pri�  mary enemy. In response, the British returned their concessions in Hankou  and Jiujiang but prepared to defend Shanghai. The alliance between the  communists and the Nationalists fell apart at that point: when communist-  led labour unions captured Shanghai for Chiang he attacked and sup�  pressed them, and when he set up his new government in Nanjing he  expelled the communists from it.

Area: 5,461 sq mi (14,144 sq km). Population (2001): 1,685,267.  Capital: Belfast. It is bounded by the republic of Ireland, the Irish Sea, the  North Channel, and the Atlantic Ocean. Northern Ireland is often referred  to as the province of Ulster. The people are descended from indigenous  Irish and immigrants from England and Scotland. Language: English  (official). Religions: Protestantism (the majority) and Roman Catholicism  (a minority). Currency: pound sterling. Northern Ireland�s industries  include engineering, shipbuilding (which has been in severe decline),  automobile manufacturing, textiles, food and beverage processing, and  clothing. The service industry employs about three-fourths of the work�  force, and manufacturing employs less than one-fifth of workers. Agri�  culture is important, with most farm income derived from livestock.  Northern Ireland shares most of its history with the republic of Ireland,  though Protestant English and Scots immigrating in the 16th-17th cen�  turies tended to settle in Ulster. In 1801 the Act of Union created the  United Kingdom, which united Great Britain and Ireland. In response to  mounting Irish sentiment in favour of Home Rule, the Government of Ire�  land Act was adopted in 1920, providing for two partially self-governing  units in Ireland: the northern six counties constituting Northern Ireland  and the southern counties now making up the republic of Ireland. In 1968  civil rights protests by Roman Catholics sparked violent conflicts with  Protestants and led to the occupation of the province by British troops in</p><p>the early 1970s. The Irish Republican Army (IRA) mounted a prolonged  campaign of violence in an effort to force the withdrawal of British troops  as a prelude to Northern Ireland�s unification with Ireland. In 1972 North�  ern Ireland�s constitution and parliament were suspended, bringing the  province under direct rule by the British. Violence continued for three  decades before dropping off in the mid-1990s. In 1998 talks between the  British government and the IRA resulted in a peace agreement that pro�  vided for extensive Home Rule in the province. In 1999 power was  devolved to an elected assembly, though the body was hampered by fac�  tional disagreements. Sporadic sectarian strife continued in the early 21st  century, as the IRA gradually carried out decommissioning (disarming).</p><p>Northern Mariana Islands Self-governing commonwealth (pop.,  2005 est.: 80,400) in political union with the U.S., in the western Pacific  Ocean. Composed of 22 islands north of Guam, the Northern Marianas  extend 450 mi (720 km) and have an area of 184 sq mi (477 sq km). The  capital, Chalan Kanoa, is on Saipan. Saipan, Tinian, and Rota are the prin�  cipal inhabited islands. Others include Alamagan and Agrihan; Pagan was  evacuated for a time after a 1981 volcanic eruption. The indigenous people  are Micronesian; other inhabitants are Chamorro and Filipino. The islands  were discovered by Ferdinand Magellan in 1521. They were colonized by  Spain in 1668. Sold by Spain to Germany in 1899, they were occupied  by Japan in 1914 and became a Japanese mandate from the League of  Nations after 1919. They were the scene of fierce fighting in World War  II; Tinian was the base for U.S. planes that dropped atomic bombs on  Hiroshima and Nagasaki. The Northern Marianas were granted to the U.S.  as a UN trust territory in 1947 and became self-governing in 1978 (when  the residents became U.S. citizens). The UN trusteeship ended in 1986.</p><p>Northern Pacific Railway Co. Major U.S. railroad that operated  between St. Paul and Seattle. It was chartered by Congress in 1864 to  build a line from Lake Superior to the Pacific coast. Financed by Jay Cooke  until 1873, it was later completed with Henry Villard�s backing. Finan�  cially troubled in the 1890s, it was reorganized by J. P. Morgan. He shared  control of it with James J. Hill, whose Great Northern Railway Co. was a  competitor and who sought to combine the two railroads with the Chi�  cago, Burlington and Quincy through the Northern Securities Co. This  arrangement was declared a violation of antitrust laws by the Supreme  Court in 1904, but the three railroads remained financially linked and in  1970 were permitted to merge as the Burlington Northern, Inc. Burling�  ton Northern acquired the St. Louis-San Francisco Railway Co. in 1980  and the Santa Fe Pacific Corp. in 1995.</p><p>Northern Rhodesia See Zambia</p><p>Northern Territory Territory (pop., 2001 prelim.: 200,019), northern  Australia. It covers an area of 520,900 sq mi (1,349,130 sq km). Its capital  is Darwin; the only other sizable town is Alice Springs. Most of the people  are of European descent; about one-fifth are Australian Aboriginals. It con�  sists mainly of tableland, with the Simpson Desert in the southeast and the  Arnhem Land plateau in the north. It was inhabited by Aboriginals for thou�  sands of years; they held Ayers Rock as central to their culture. The coast  was explored by the Dutch in the 17th century and surveyed in the early  19th century by Matthew Funders. First included as part of New South  Wales, it was annexed to South Australia in 1863. It reverted to being  under direct control of the Commonwealth of Australia in 1911. The  northern parts were bombed by the Japanese in World War II and occupied  by Allied troops. It was granted self-government within the Common�  wealth in 1978. It remains sparsely inhabited; its economy rests on cattle  farming, mining, government services, and a growing tourism industry.</p><p>Northern War, First (1655 -60) Final stage of the struggle over the  Polish-Swedish succession. In 1655 the Swedish king Charles X Gustav  declared war on Poland on the pretext that it refused to recognize him as  king. In alliance with Brandenburg, Sweden invaded Poland with initial  success, but when Russia, Denmark, and Austria declared war on Swe�  den, Brandenburg deserted to join the coalition. The Swedes were driven  from Poland but later twice invaded Denmark. The war ended with the  Polish sovereigns renouncing their claim to the Swedish throne and the  Swedes acquiring Skane from Denmark.</p><p>Northern War, Second or Great Northern War (1700-21)  Military conflict to challenge Sweden�s supremacy in the Baltic area.  Sweden�s expansion in the Baltic Sea coastlands antagonized Russia,  Denmark-Norway, and Saxony-Poland, which formed an anti-Swedish  coalition in 1698. They attacked Swedish-held regions in 1700, but Swe�  den�s Charles XII successfully countered the attacks and restored the sta-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Northern Wei dynasty &#x25BA; Norway I 1381</p><p>tus quo. The Russians eventually succeeded in establishing their power  on the eastern Baltic coast, and Peter I the Great founded his new capital  of St. Petersburg there in 1703. Sweden renewed its attack on Russia in  1707, but was defeated at the Battle of Poltava (1709). Despite an alli�  ance with Turkey against Russia (1710-11), Swedish forces suffered  defeats in its territories by the revived anti-Swedish coalition, which by  then included England and Prussia. Charles opened peace negotiations in  1717, but in 1718 he invaded southeastern Norway, where he was killed.  His successor, Frederick I (1676-1751), negotiated peace settlements in  1719-21, including the Treaty of Nystad, which ceded Estonia, Livonia,  and other territory to Russia. The war marked the decline of Swedish  influence and the emergence of Russia as a major power.</p><p>Northern Wei dynasty or Toba dynasty (ad 386-534/35)  Longest-lived and most powerful of the northern Chinese dynasties that  ruled after the Han dynasty fell and before the Sui and Tang dynasties  reunified China. Founded by Toba tribesmen, the Northern Wei defended  its territory against other northern nomads and by 439 had unified all of  northern China. The Wei lifestyle became more sedentary, and the Toba  people, impressed by Chinese culture, began to emulate the Chinese. To  bring into cultivation land abandoned during war, hundreds of thousands  of peasants were relocated and allocated land under the equal-field system  of land distribution. The rulers of the Northern Wei were great patrons of  Buddhism, and the period is noted for its Buddhist art, particularly at the  caves of Yungang. The one exception, the emperor Taiwu, persecuted  Buddhists and supported Daoism.</p><p>Northern Wei sculpture Chinese sculpture, dominated by simple  images of the Buddha, dating from the era of the Northern Wei dynasty  (ad 386-534/535). The art represents the first major influence of Buddhism  on China, and may be divided into two major periods. The first style (c.  452-494), an amalgam of foreign influences traceable to the Buddhist art  of India, is characterized by heavy stylization of blocky volumes. The  second style (c. 494-535) clothes the Buddha in the costume of the Chi�  nese scholar and emphasizes a sinuous cascade of drapery falling over an  increasingly flattened figure.</p><p>Northrop Vnor-thropV John Howard (b. July 5, 1891, Yonkers,  N.Y., U.S.�d. May 27, 1987, Wickenberg, Ariz.) U.S. biochemist. He  worked most of his career on the staff of New York City�s Rockefeller  Institute for Medical Research (1916-61). His early research on fermen�  tation processes led to a study of enzymes essential for digestion, respira�  tion, and general life processes. He established that enzymes obey the laws  of chemical reactions, and he crystallized pepsin, trypsin, and chymotrypsin  and their zymogens. With James Sumner and Wendell Meredith Stanley he  shared a 1946 Nobel Prize.</p><p>Northumberland Administrative (pop., 2001: 307,186) and historic  county, northeastern England. It includes several islands, including Lind-  isfame (Holy Island), and much of the ancient Anglo-Saxon kingdom of  Northumbria. The landscape is varied, with coastal plains in the east, the  rugged Cheviot Hills and moors in the west, and industrial areas in the  southern River Tyne valley. It was the site of prehistoric settlement before  the Roman domination began in ad 122, when Hadrian's Wall was built.  It was the scene of border warfare with Scotland until the union of Scot�  land with England in 1603. Good farmland is limited; industrial com�  plexes produce heavy machinery.</p><p>Northumberland, John Dudley, duke of (b. 1502�d. Aug. 22,  1553, London, Eng.) English politician. After serving as deputy governor  of English-occupied Calais (1538) and lord high admiral (1542), he fought  in the invasion of Scotland (1544) and captured the French city of Bou�  logne (1544). He was created earl of Warwick (1546) and in 1547 became  a member of the regency council that governed for the young Edward VI.  After engineering the fall of the duke of Somerset, Warwick assumed con�  trol of the regency (1550). He made himself duke of Northumberland in  1551 and ordered Somerset�s arrest and execution in 1552. He imposed  strict conformity to Protestant doctrine in support of the Reformation. In  1553 he persuaded the dying Edward VI to will the crown to Northum�  berland�s daughter-in-law, Lady Jane Grey; thwarted by supporters of  Mary Tudor (Mary I), he was arrested and executed for treason.</p><p>Northumbria Anglo-Saxon kingdom of Britain. Located between the  River Humber and the Firth of Forth, it extended from the Irish Sea to  the North Sea. Its religious, artistic, and intellectual achievements in the  7th-8th centuries were epitomized by such centres as Lindisfame and the  monasteries of Wearmouth and Jarrow. Jarrow, with its fine library, was</p><p>the home of the Venerable St. Bede. After Northumbria�s expansion in the  7th century, it became the most powerful of the Anglo-Saxon kingdoms  before being destroyed by the Danes, who captured York in 866. In 944  the last Scandinavian ruler of York was expelled, and Northumbria  became an earldom within the kingdom of England.</p><p>Northwest Coast Indian Any member of the North American Indian  peoples inhabiting a narrow but rich belt of coastland and offshore islands  from southeast Alaska to northwestern California. A signal feature of  Northwest Coast society was the emphasis on each individual�s heredi�  tary social rank. A person�s position within a local group depended on his  genealogical closeness to the legendary group ancestor. For food the  peoples of the area depended primarily on five species of salmon; her�  ring; oil-rich �candlefish,� or eulachon; smelt; cod; halibut; and  mollusks�all of which were abundant. Water transport was highly impor�  tant, and all groups made efficient dugout canoes. Northwest Coast wood�  working was facilitated by the natural abundance of easily worked  timbers, especially red cedar and redwood. Groups of the Northwest Coast  include, from north to south, Tlingit, Haida, Tsimshian, northern Kwakiutl  (Heiltsuq), Bella Coola, southern Kwakiutl, Nootka, Coast Salish, Chi�  nook, and a series of lesser divisions.</p><p>Northwest Ordinances (1784, 1785,1787) Measures enacted by the  U.S. Congress for the division and settlement of the Northwest Territory,  the frontier region extending north of the Ohio River to the Great Lakes  and west of Pennsylvania to the Mississippi River. The original ordinance,  written by Thomas Jefferson, divided the territory into self-governing dis�  tricts and set population requirements for statehood. The final ordinance,  written partly by Rufus King, set land-grant sizes and prices, provided  public land for schools, outlawed slavery, and guaranteed civil liberties.  It established the principle of admitting new states on equal terms with  the original 13 states.</p><p>Northwest Passage Sea passage between the Atlantic and Pacific  oceans along the northern coast of North America. The search for a com�  mercial sea route around the American land barrier dates from the end of  the 15th century and attracted explorers such as Jacques Cartier, Francis  Drake, Martin Frobisher, and Capt. James Cook. The passage was finally  navigated successfully in 1903-05 by Roald Amundsen. As a modern trade  route it has been only marginally useful, because of the difficulties in  navigating around the polar ice cap and the giant icebergs in the Atlantic  between Greenland and Baffin Island and in the Pacific in the Bering  Strait. The U.S. and Canadian governments have tried to encourage inter�  national commerce in the passage, noting how much it would shorten  many international shipping distances. However, the cost of strengthen�  ing ships against ice and potentially high insurance rates for vessels used  in Arctic service have been factors inhibiting the development of the  Northwest Passage as a trade route.</p><p>Northwest Territories Territory (pop., 2001 est.: 40,900), northern  Canada. Bounded by the Yukon Territory, Hudson Bay, and Nunavut, it  stretches across the roof of the North American continent, reaching into  the Arctic Circle. The capital is Yellowknife. It includes many islands,  including Victoria Island; the Mackenzie River; and Great Bear and Great  Slave lakes. More than half the people are Inuit (Eskimos) and American  Indians. In the 18th century the mainland was explored by Samuel Hearne  for the Hudson's Bay Company and by Alexander Mackenzie. European set�  tlers were mainly whalers, fur traders, and missionaries until the 1920s,  when oil was discovered and the territorial administration was formed.  Mining is the principal industry and centres on the petroleum and natural  gas fields in the western Arctic coastal regions.</p><p>Northwestern University Private university in Evanston, Illinois,  U.S., founded in 1851. It is a comprehensive research institution that  includes a college of arts and sciences and schools of music, education,  social policy, graduate studies, law, medicine, and dentistry. It also  includes the Medill School of Journalism, the McCormick School of Engi�  neering and Applied Science, and the Kellogg Graduate School of Man�  agement. Research facilities include centres for the study of learning,  urban affairs and policy, and superconductivity.</p><p>Norway officially Kingdom of Norway Country, western Scandi�  navian Peninsula, northern Europe.

It has a developed economy largely based on services, petroleum and  natural gas production, and light and heavy industries. Literacy is virtu�  ally 100%. Norway is a constitutional monarchy with one legislative  house; its chief of state is the king, and the head of government is the  prime minister. Several principalities were united into the kingdom of  Norway in the 11th century. It had the same king as Denmark from 1380  to 1814, when it was ceded to Sweden. The union with Sweden was dis�  solved in 1905, and Norway�s economy grew rapidly. It remained neu�  tral during World War I, although its shipping industry played a vital role  in the conflict. It declared its neutrality in World War II but was invaded  and occupied by German troops. Norway maintains a comprehensive wel�  fare system and is a member of NATO. Its citizens rejected membership  in the European Union in 1994.</p><p>Norway lobster See scampi</p><p>Norwegian language North Germanic language of the West Scan�  dinavian branch, spoken by some five million people in Norway and the  U.S. Old Norwegian became a separate language by the end of the 12th  century. Middle Norwegian became the tongue of most native speakers  about the 15th century. Modern Norwegian has two rival forms. Dano-  Norwegian (Bokmal, or Riksmal), the more popular, stems from written  Danish used during the union of Denmark and Norway (1380-1814; see  Kalmar Union). It is used in national newspapers and most literary works.  New Norwegian (Nynorsk), based on western rural dialects, was created  by Ivar Aasen (1813-96) in the mid-19th century to carry on the tradi�  tion of Old Norse. Both languages are used in government and education.  Plans to unite them gradually in a common language, Samnorsk, were  officially abandoned in 2002.</p><p>Norwegian Sea Open sea, Northern Hemisphere. It is bordered by  Greenland, Iceland, Spitsbergen, and Norway. A submarine ridge linking  Greenland, Iceland, the Faroe Islands, and northern Scotland separates the  Norwegian Sea from the Atlantic Ocean. The sea is crossed by the Arctic  Circle, but the warm Norway Current that flows northeast off the Norway  coast produces generally ice-free conditions. Colder currents mixing with  this warm water create excellent fishing grounds.</p><p>Norwich Vnor-ich\ City (pop., 2001: 121,553), administrative and his�  toric county, Norfolk, England. Located on the River Wensum northeast  of London, it had become an important market centre when it was sacked</p><p>and occupied by the Danes in the 11th century. It was among the most  prosperous English provincial towns for centuries; its economy was fos�  tered by Edward III, who induced Flemish weavers to settle there, and by  the influx of immigrants during the reign of Elizabeth I. One of England�s  largest centres of footwear manufacturing, it features a Norman castle and  cathedral. It is the traditional regional capital of East Anglia and the site  of a cathedral founded shortly after the Norman Conquest.</p><p>nose Prominent structure between and below the eyes. With the com�  plex nasal cavity behind it, it functions for breathing and smelling. Behind  the front section (vestibule), which includes the nostrils, it is divided ver�  tically by three convoluted ridges (conchae) into air passages. In the high�  est one, the olfactory region, a small segment of mucous membrane lining  contains neurons covered by a moisture layer, in which microscopic par�  ticles in inhaled air dissolve and stimulate the neurons. The rest of the  cavity warms and moistens inhaled air and filters particles and bacteria  out of it. Sinus cavities in the bone on both sides of the nose drain into  the air passages. During swallowing, the soft palate closes off the back of  the nose against food.</p><p>Nossob \'no-,sab\ River or Nosop Vno-,sap\ River River, southern  Africa. Rising in central Namibia, it flows southeast through the western  Kalahari Desert and forms part of the border between Botswana and South  Africa, bisecting the Kalahari Gemsbok National Park (now part of Kgal-  agadi Transfrontier Park). It joins the Auob River before emptying into  the Molopo River, which flows into the Atlantic Ocean. It is about 500  mi (800 km) long. Because of irregular rainfall, in the 20th century the  lower Nossob�s riverbed contained flowing water only a few times.</p><p>nostoc \'na-,stak\ Any of the cyanobacteria that make up the genus Nos-  toc. The cells are arranged in beadlike chains grouped together in a gelati�  nous mass. Ranging from microscopic to walnut-sized, nostoc masses  may be found on soil and floating in still water. A special thick-walled  cell has the ability to withstand drying for long periods of time. After 70  years of dry storage, cells of one species can germinate into filaments  when moistened. Like most other cyanobacteria, nostocs contain two pig�  ments and are capable of nitrogen fixation.</p><p>Nostradamus X.nas-tro-'da-mosV orig. Michel de Notredame (b.</p><p>Dec. 14, 1503, Saint-Remy, France�d. July 2, 1566, Salon) French  astrologer and physician known for his prophecies. He practiced medi�  cine in southern France from 1529 and gained a reputation for his inno�  vative treatment of plague victims in 1546-47. He began making  prophecies in 1547, and in 1555 they were published in a book titled Cen�  turies. He wrote them in rhymed quatrains, using a cryptic style that  mingled French, Latin, Spanish, and Hebrew. Catherine de Medicis invited  him to her court as an astrologer, and in 1560 he was appointed physi�  cian to Charles IX. His prophecies are still widely read; readers have dis�  covered apparent predictions of such world events as the French  Revolution and World War I.</p><p>Nostratic \no-'strat-ik\ hypothesis Proposal of an overarching north�  ern Eurasian language family, still of uncertain validity. Holger Pedersen  was the first to suggest that the Indo-European, Uralic, Altaic, Afroasiatic,  and other language families might belong in one broad category (Nos�  tratic). In the 1960s Vladislav Illich-Svitych made a detailed case in  favour of the hypothesis and added Kartvelian (see Caucasian languages)  and Dravidian to the list; he began reconstructing Proto-Nostratic but died  in 1966 before finishing. Important contributions to this theory were also  made by the Russian-born Israeli linguist Aron Dolgopolsky. The hypoth�  esis remains highly controversial.</p><p>notary or notary public Public officer who certifies and attests to  the authenticity of writings (e.g., deeds) and takes affidavits, depositions,  and protests of negotiable instruments. The notary is commissioned by the  state and may act only within the territory authorized by state statutes.  Most states set maximum fees for notarial services and require that a  notarial seal or stamp be impressed on documents authenticated by a  notary public. In the civil-law countries of western Europe and in Latin  American and French areas of North America, the role of the notary is  more significant, being roughly equivalent to that of a lawyer who spe�  cializes in real estate, sales, mortgages, and the settlement of estates but  who may not appeal� in court.</p><p>notation, musical See musical notation</p><p>Noto \'no-to\ Peninsula Peninsula, Honshu, Japan.

He may have devised the rhythmic notation (ligatures) that  made this possible or at least codified the important system of rhythmic  modes. His younger contemporary Perotin (fl. c. 1200) is said to have  edited, extended, and added parts to Leonin�s Magnus liber organi (�Great  Book of Organum�) and created the first three- and four-voice textures  known in world music.

Most appear to be close  binary stars, one of which is a white dwarf star drawing in matter from the  other until it becomes unstable, causing an outburst in which the outer  layer of material is shed. A nova reaches maximum luminosity within  hours after its outburst and may shine intensely for several days or even  a few weeks; it then slowly returns to its former level. The process can  repeat at intervals ranging from a few dozen to hundreds of thousands of  years. Stars that become novas are usually too faint to see with the unaided  eye until their sudden increase in luminosity, sometimes great enough to  make them readily visible in the night sky. To observers, such objects may  appeal* to be new stars; hence their name (Latin for �new�).

It comprises the peninsula of Nova Scotia,  Cape Breton Island, and a few small adjacent islands, and it is bounded  by the Northumberland Strait, the Gulf of St. Lawrence, the Atlantic  Ocean, the Bay of Fundy, and New Brunswick. Its capital is Halifax. The  region was first visited by Vikings c. ad 1000 and was inhabited by Mic-  mac Indians when John Cabot claimed it for England in 1497. French set�  tlers in 1605 adopted the Micmac name Acadia for the region. English  and Scottish colonists arrived by 1621. The conflict between France and  England over control of the area was ended by the 1713 Peace of Utrecht,  which awarded it to England. In the 1750s, the British expelled most of  the French settlers. Following the American Revolution, many loyalists  emigrated there.

The genre encompasses a wide range of types and styles, includ�  ing picaresque, epistolary, gothic, romantic, realist, and historical novels.  Though forerunners of the novel appeared in a number of places, includ�  ing Classical Rome and 11th-century Japan, the European novel is usu�  ally said to have begun with Miguel de Cervantes�s Don Quixote. The novel  was established as a literary form in England in the 18th century through  the work of Daniel Defoe, Samuel Richardson, and Henry Fielding. The typi�  cal elements of a conventional novel are plot, character, setting, narrative  method and point of view, scope, and myth or symbolism. These elements  have been subject to experimentation since the earliest appearance of the  novel. Compare antinovel. See also novella; short story.</p><p>novella Story with a compact and pointed plot, often realistic and satiric  in tone. Originating in Italy during the Middle Ages, it was often based  on local events; individual tales often were gathered into collections. The  novella developed into a psychologically subtle and structured short tale,  with writers frequently using a frame story to unify tales around a theme,  as in Giovanni Boccaccio�s Decameron. The term is also used to describe  a work of fiction intermediate in length�and sometimes complexity�  between a short story and a novel. Examples of novellas include Fyodor  Dostoyevsky�s Notes from the Underground (1864), Joseph Conrad�s Heart  of Darkness (1902), Thomas Mann�s Death in Venice (1912), and Henry  James�s The Aspern Papers (1888).</p><p>Noverre \no-'ver\, Jean-Georges (b.

This innovative approach�called ballet d�action, or  �ballet with a story��brought major reforms in ballet production. His  invention of ballet d�action was challenged by Gasparo Angiouni, who  had developed a simpler approach to the new form. In 1776 Noverre  became ballet master of the Paris Opera.</p></section><section><p>Novgorod Vnov-go-roA City (pop., 2002: 217,200), northwestern Rus�  sia. Located on the Volkhov River north of Lake Ilmen, it is one of the  oldest Russian cities. First mentioned in the chronicles of ad 859, it came  under Rurik c. 862. It was of great importance in the 11th to 15th centu�  ries, when it was the capital of the principality of Novgorod. It prospered  by trade with Central Asia, Byzantium, and the Hanseatic League. The  centre of the Novgorod school of painting, it was ruled by Alexander  Nevsky in the 13th century. It became a rival of Moscow, was destroyed  by Ivan IV in 1570, and declined with the rise of St. Petersburg. It was held  by the Germans in World War II and suffered heavy damage. Many his�  toric buildings were later restored, and these were designated a UNESCO  World Heritage site in 1992. The city is a centre of tourism.</p><p>Novgorod school Important school of Russian medieval icon and  mural painting that flourished around Novgorod in the 12th-16th centu�  ries. Novgorod, Russia�s cultural centre in the 13th�14th centuries, when  most of the rest of the country was occupied by the Mongols, preserved  the Byzantine traditions that formed the basis of Russian art but intro�  duced lighter and brighter colours, flatter forms, softening of facial types,  and increasing use of a graceful, rhythmic line to define form. Until the  early 14th century, artistic activity was dominated by mural painting. A</p><p>new artistic impetus was provided by  the introduction of the iconostasis.</p><p>When icons were displayed together  on the iconostasis rather than scat�  tered about the walls of the church,  they demanded a coherent overall  impression, which was achieved by  strong, rhythmic lines and colour  harmonies. Figures took on the elon�  gated shape that became standard in  Russian art.

His best-known work, Anarchy, State, and Uto�  pia (1974), is a closely argued and highly original defense of the liber�  tarian �minimal state� (a state whose powers are limited to those necessary  to protect citizens against violence, theft, and fraud) and a critique of the  social-democratic liberalism of his Harvard colleague John Rawls. Against  anarchism, Nozick argued that the minimal state is justified because it  would arise in a state of nature through transactions that would not vio�  late anyone�s natural rights (see natural law); against liberalism and ide�  ologies farther left, he argued that no more than the minimal state is  justified because any state with more extensive powers would violate the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>NPR &#x25BA; nuclear magnetic resonance I 1385</p><p>natural rights of its citizens.

For about 1,800 years in  ancient times it was politically dominated by Egypt, although Nubian  kings did sit on the Egyptian throne during the 25th dynasty. The king�  dom of Kush and its culture were centred in southern Nubia.

In 1919 Ernest Rutherford discovered that  alpha rays could split the nucleus of an atom. This led ultimately to the  discovery of the neutron and the release of huge amounts of energy by  the process of nuclear fission. Nuclear energy is also released as a result  of nuclear fusion. The release of nuclear energy can be controlled or  uncontrolled. Nuclear reactors carefully control the release of energy,  whereas the energy release of a nuclear weapon or resulting from a core  meltdown in a nuclear reactor is uncontrolled. See also chain reaction,  NUCLEAR POWER, RADIOACTIVITY.</p><p>nuclear fission Division of a heavy atomic nucleus into two fragments  of roughly equal mass, accompanied by the release of a large amount of  energy, the binding energy of the subatomic particles. The energy released  in the fission of one uranium nucleus is about 50 million times greater  than that released when a carbon atom combines with oxygen atoms in  the burning of coal. The energy appeal's as kinetic energy of the fragments,  which converts to thermal energy as the fragments collide in matter and  slow down. Fission also releases two or three free neutrons. The free neu�  trons can bombard other nuclei, leading to a series of fissions called a  chain reaction. The energy released from nuclear fission is used to gen�  erate electricity, to propel ships and submarines, and is a source of the  vast destructive power of nuclear weapons. See illustration opposite.</p><p>nuclear fusion Process by which nuclear reactions between light ele�  ments form heavier ones, releasing huge amounts of energy. In 1939 Hans</p><p>Bethe suggested that the energy output of the sun and other stars is a result  of fusion reactions among hydrogen nuclei. In the early 1950s American  scientists produced the hydrogen bomb by inducing fusion reactions in a  mixture of the hydrogen isotopes deuterium and tritium, forming a heavier  helium nucleus. Though fusion is common in the sun and other stars, it  is difficult to produce artificially and is very difficult to control. If con�  trolled nuclear fusion is achieved, it might provide an inexpensive energy  source because the primary fuel, deuterium, can be extracted from ordi�  nary water, and eight gallons of water could provide the energy equiva�  lent to 2,500 gallons of gasoline.

Nuclei that have at least one unpaired proton or  neutron act like tiny magnets. When a strong magnetic field acts on such  nuclei, it sets them into precession. When the natural frequency of the pre-  cessing nuclear magnets corresponds to the frequency of a weak external  radio wave striking the material, energy is absorbed by the nuclei at a  frequency called the resonant frequency. NMR is used to study the  molecular structure of various solids and liquids. Magnetic resonance  imaging, or MRI, is a version of NMR used in medicine to view soft tis�  sues of the human body in a hazard-free, noninvasive way.</p><p>nuclear medicine Medical specialty using radioactive elements or iso�  topes for diagnosis and treatment of disease. A radioisotope is introduced  into the body (usually by injection). The radiation it emits, detected by a  scanner and recorded, reflects its distribution in different tissues and can  reveal the presence, size, and shape of abnormalities in various organs.  The isotopes used have short half-lives and decay before radioactivity  causes any damage. Different isotopes tend to concentrate in particular  organs (e.g., iodine-131 in the thyroid). Radioactive substances are also  implanted to treat small, early-stage cancers. This yields a slow, continu�  ous dose that limits damage to normal cells while destroying tumour cells.

It was  signed by the U.S., Britain, the Soviet Union, and 59 other countries in  1968. The three major signatories agreed not to assist states lacking  nuclear weapons to obtain or produce them; the nonnuclear signatories  agreed not to attempt to obtain nuclear weapons in exchange for assis�  tance in developing nuclear power for peaceful purposes. France and  China, both nuclear powers, declined to ratify the treaty until 1992, and  some nuclear powers, including Israel and Pakistan, have never signed it.  In 1995, when the treaty was due to expire, it was extended indefinitely  by a consensus vote of 174 countries at the United Nations. See also  Nuclear Test-Ban Treaty.</p><p>nuclear physics Branch of physics dealing with the structure of the  atomic nucleus and radiation from unstable nuclei. A principal research  tool of nuclear physics is a high-energy beam of particles, such as pro�  tons or electrons, directed as projectiles against nuclear targets. By ana�  lyzing the directions and energies of the recoiling particles and any  resulting nuclear fragments, nuclear physicists can obtain details of  nuclear structure, the strong force that binds nuclear components together,  and the release of energy from the nucleus.</p><p>nuclear power Energy produced by nuclear fission of heavy atomic  nuclei. About one-third of all electric power worldwide now comes from  nuclear power plants. The navies of many countries include nuclear-  powered warships; almost half of U.S. combat warships are nuclear-  powered. Most commercial nuclear reactors are thermal reactors. Two  types of light-water reactors in use throughout the world are the boiling-  water reactor and the pressurized-water reactor. In the liquid-metal fast-  breeder reactor, fuel is utilized 60 times more effectively than in light-  water reactors. See also nuclear energy.</p><p>nuclear reactor Device that can initiate and control a self-sustaining  series of nuclear-fission reactions. Neutrons released in one fission reac�  tion may strike other heavy nuclei, causing them to fission. The rate of  this chain reaction is controlled by introducing materials, usually in the  form of rods, that readily absorb neutrons. Typically, control rods made  of cadmium or boron are gradually inserted into the core if the series of  fissions begins to proceed at too great a rate, which could lead to melt�  down of the core. The heat released by fission is removed from the reac�  tor core by a coolant circulated through the core. Some of the thermal  energy in the coolant is used to heat water and convert it to high-pressure  steam. This steam drives a turbine, and the turbine�s mechanical energy  is then converted into electricity by means of a generator. Besides pro�  viding a valuable source of electric power for commercial use, nuclear  reactors also serve to propel certain types of military surface vessels, sub�  marines, and some unmanned spacecraft. Another major application of  reactors is the production of radioactive isotopes that are used extensively  in scientific research, medical therapy, and industry.</p><p>Nuclear Regulatory Commission (NRC) U.S. independent regu�  latory agency that oversees the civilian use of nuclear energy. Established  in 1974 to replace the Atomic Energy Commission, the NRC licenses the</p><p>construction and operation of nuclear reactors and other facilities and the  ownership and use of nuclear materials. It issues standards, rules, and  regulations for the maintenance of licenses, and it regularly inspects  nuclear facilities to ensure compliance with public health and safety, envi�  ronmental quality, national security, and antitrust laws. The NRC also  investigates nuclear accidents, conducts public hearings, and reviews  power-plant operations. Its commissioners are appointed by the president  of the U.S.</p><p>nuclear species See nuclide</p><p>Nuclear Test-Ban Treaty officially Treaty Banning Nuclear  Weapons Tests in the Atmosphere, in Outer Space and  Under Water Treaty that prohibits all tests of nuclear weapons except  those conducted underground. U.S.-Soviet test-ban talks began after con�  cerns arose in the 1940s and �50s about the dangers of radioactive fallout  from above-ground nuclear tests. These talks made little progress until  the Cuban missile crisis of 1962. In the following year, Britain, the U.S.,  and the Soviet Union signed the treaty, and more than 100 other govern�  ments soon followed. France and China were notable nonsignatories. In  1996 the treaty was replaced by the Comprehensive Test-Ban Treaty,  which will not take effect until it is signed by all 44 countries with nuclear  power plants. India refuses to do so on the ground that the treaty lacks  disarmament provisions and permits nonexplosive testing. See also  Nuclear Non-proliferation Treaty.</p><p>nuclear weapon or atomic weapon or thermonuclear  weapon Bomb or other warhead that derives its force from nuclear fis�  sion, nuclear fusion, or both and is delivered by an aircraft, missile, or  other system. Fission weapons, commonly known as atomic bombs, release  energy by splitting the nuclei of uranium or plutonium atoms; fusion  weapons, known as hydrogen bombs or thermonuclear bombs, fuse nuclei  of the hydrogen isotopes tritium or deuterium. Most modern nuclear  weapons actually combine both processes. Nuclear weapons are the most  potent explosive devices ever invented. Their destructive effects include  not only a blast equivalent to thousands of tons of TNT but also blinding  light, searing heat, and lethal radioactive fallout. The number of nuclear  weapons reached its peak in the 1980s, when the U.S. had some 33,000  and the Soviet Union 38,000. Since the end of the Cold War both coun�  tries have decommissioned or dismantled thousands of warheads. Other  declared nuclear powers are the United Kingdom, France, China, India,  and Pakistan. Israel is widely assumed to possess nuclear weapons, and  North Korea, Iran, and Iraq often have been accused of seeking to build  them. Some countries, such as South Africa, Brazil, and Argentina, have  acknowledged pursuing nuclear weapons in the past but have abandoned  their programs. See also Nuclear Non-proliferation Treaty; Nuclear Test-  Ban Treaty.</p><p>nuclear winter Environmental devastation that some scientists con�  tend would result from a nuclear war. The basic cause, as hypothesized,  would be huge fireballs created by exploding nuclear warheads, which  would ignite great fires (firestorms). Smoke, soot, and dust would be lifted  to high altitudes and driven by winds to form a uniform belt encircling  the Northern Hemisphere. The clouds could block out all but a fraction  of the Sun�s light, and surface temperatures would plunge for as much as  several weeks. The semidarkness, killing frosts, and subfreezing tempera�  tures, combined with high doses of radiation, would interrupt plant pho�  tosynthesis and could thus destroy much of the Earth�s vegetation and  animal life. Other scientists dispute the results of the original calculations,  and, though such a nuclear war would undoubtedly be devastating, the  degree of damage to life on the Earth remains controversial.</p><p>nucleic \nu-'kle-ik, nu-�kla-ik\ acid Any of the organic compounds  making up the genetic material of living cells. Nucleic acids direct the  course of protein synthesis, thereby regulating all cell activities. Their  transmission from one generation to the next is the basis of heredity. The  two main types, DNA and RNA, are composed of similar materials but  differ in structure and function. Both are long chains of repeating nucle�  otides. The sequence of purines and pyrimidines (bases)� adenine (A), gua�  nine (G), cytosine (C), and either thymine (T; in DNA) or uracil (U; in  RNA)�in the nucleotides, in groups of three (triplets, or codons), con�  stitutes the genetic code.</p><p>nucleolus See nucleus</p><p>nucleophile \ , nu-kle-3- 1 fil\ Atom or molecule that contains an electron  pair available for bonding and in chemical reactions therefore seeks a posi-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>nudeoprotein &#x25BA; Nullarbor Plain I 1387</p><p>tive centre, such as the nucleus of an atom or the positive end of a polar  molecule (see covalent bond; electric dipole). In the Lewis electron theory  (see acid-base theory), advanced by the U.S. chemist Gilbert Lewis ( 1 875�  1946) in 1923, nucleophiles are by definition Lewis bases. Examples  include the hydroxide ion (OH - ), the ions of the halogens chlorine, bro�  mine, and iodine (Cl - , Br - , and I - , respectively), ammonia (NH 3 ), and  water (H 2 0). See also base; electrophile.</p><p>nudeoprotein V.nii-kle-o-'pro-.tenX Macromolecular complex consist�  ing of a protein linked to a nucleic acid, either DNA or RNA. The proteins  that combine with DNA are generally of characteristic types called his�  tones and protamines. The resulting nucleoproteins (deoxynucleoproteins)  make up the chromosomes of living cells. Many viRUSes are little more than  organized agglomerations of deoxynucleoproteins. Many specific RNA  nucleoproteins are also known; they have diverse cellular functions.</p><p>nucleoside \ , nu-kle-a- l sld\ Any of a class of organic compounds,  including structural subunits of nucleic acids. Each consists of a molecule  of a five-carbon sugar (ribose in RNA, deoxyribose in DNA) and a  nitrogen-containing base, either a purine or a pyrimidine. The base uracil  occurs in RNA, thymine in DNA, and adenine, guanine, and cytosine in both,  as part of the nucleosides uridine, deoxythymidine, adenosine or deoxy-  adenosine, guanosine or deoxyguanosine, and cytidine or deoxycytidine.  Nucleosides usually have a phosphate group attached, forming nucleotides.  Usually obtained by decomposition of nucleic acids, nucleosides are  important in physiological and medical research. Those that are not part  of nucleic acids include puromycin and certain other antibiotics produced  by fungi.</p><p>nucleosynthesis \ l nu-kle-o-'sin-th3-s3s\ Production on a cosmic scale  of all the chemical elements from one or perhaps two simple types of  atomic nuclei (see nucleus), those of hydrogen and helium. Elements differ  in the number of protons and isotopes of each element by the number of  neutrons in their nuclei. One type of nucleus can be transformed into  another by adding or removing protons, neutrons, or both, processes that  go on in stars. Many of the first 26 elements (up to iron) and their present  cosmic abundances can be accounted for by successive nuclear fusion  reactions, beginning with hydrogen, in stellar cores. Heavier elements are  believed to be created in the death of stars during supernova explosions,  by capture of successive neutrons by lighter nuclei and decay of some of  these neutrons into protons (with ejection of an electron and a neutrino  each time).</p><p>nucleotide Vnii-kle-o-.tldV Any of a class of organic compounds, includ�  ing the structural units of nucleic acids. Each consists of a nucleoside and  one or more phosphate groups. In nucleic acids, the phosphate of one  nucleotide joins to the sugar of the next to form the backbone. Important  nucleotides that are not part of nucleic acids include ATP, cyclic AMP  (needed in glycogen breakdown), and certain coenzymes.</p><p>nucleus Specialized structure occurring in most cells (except bacteria)  and separated from the rest of the cell by the nuclear membrane. This  membrane seems to be continuous with the cell�s endoplasmic reticulum and  has pores that permits the passage of large molecules. The nucleus con�  trols and regulates the cell�s activities (e.g., growth and metabolism) and  carries the genes. Nucleoli are small bodies often seen within the nucleus  that play an important part in the synthesis of RNA and protein. A cell  normally contains only one nucleus.</p><p>nucleus Central, positively charged core of an atom. It consists of posi�  tively charged protons and neutral neutrons, known collectively as nucle�  ons, held together by the strong force. The number of nucleons can range  from 1 to about 270, depending on the element. Isotopes are atoms of the  same element that have the same number of protons but different num�  bers of neutrons. Some nuclei, especially heavier ones, are unstable, or  radioactive (see radioactivity), emitting energy in the form of alpha rays  (see alpha decay), beta rays (see beta decay), or gamma rays. The nucleus  makes up nearly all the mass but only a minute fraction of the volume of  the atom.</p><p>nuclide or nuclear species Species of atom as characterized by the  number of protons, neutrons, and the energy state of the nucleus. A nuclide  is characterized by its mass number and its atomic number. To be regarded  as distinct, a nuclide must have an energy content sufficient for a mea�  surable lifetime, usually more than 10 -10 second. Nuclear isomers, which  have the same number of protons and neutrons but differ in energy con�  tent and radioactivity, are also distinct nuclides. Nuclides are associated</p><p>with radioactive decay and may be stable or unstable. There are about  1,700 known nuclides, of which about 300 are stable and the rest radio�  active.</p><p>nudibranch \ , n(y)u-d3-,brai]k\ or sea slug Any marine gastropod in  the order Nudibranchia. Most nudibranchs lack a shell, mantle cavity (see  mollusk), and gills, and breathe through the body surface. The delicately  colored body, up to 16 in. (43 cm) long, has bizarre defensive outgrowths,  called cerata, that discharge nematocysts ingested from cnidarian prey.  Antennalike organs arise from the head. Nudibranchs occur in shallow  waters of all oceans, where they feed chiefly on other invertebrates, par�  ticularly sea anemones. Some species can swim; others are bottom creep�  ers. The term sea slug sometimes refers to all members of the subclass  Opisthobranchia.</p><p>nuee ardente \nu-'a-ar- , dant\ French "fiery or glowing cloud"</p><p>Highly destructive, incandescent mass of gas-enveloped particles that is  associated with volcanic eruptions. These glowing avalanches, as they are  sometimes called, can move down even slight inclines at speeds as high  as 100 mph (160 kph). The temperature of the gases can reach 1,100�  1,300 �F (600-700 �C). Nuees ardentes are exceedingly destructive, kill�  ing all living things in their path. Most occur in the circum-Pacific region  known as the Ring of Fire. See also tuff.</p><p>Nuer Vnti-ar\ People of the marsh and savanna living on both banks of  the Nile River in southern Sudan. They speak an Eastern Sudanic lan�  guage of the Nilo-Saharan family. The Nuer are cattle-raising people who  also cultivate millet and spear fish. They spend the rainy season in per�  manent villages on the higher ground and the dry season in riverside  camps. Feuding between clans is common, as is warfare with the Dinka.  They number 1.5 million. See also Nilot.</p><p>Nuevo Leon \'nwa-v6-la-'6n\ State (pop., 2000: 3,834,141), northeast�  ern Mexico. It covers an area of 25,067 sq mi (64,924 sq km), and its  capital is Monterrey. The Sierra Madre Oriental crosses the state from  northwest to southeast. The region became a state in 1824 and was occu�  pied by U.S. troops during the Mexican War. Its iron and steel industries  were the first heavy industry in Latin America; the state also supports  agricultural and textile enterprises.</p><p>nuisance In law, an act, object, or practice that interferes with anoth�  er�s rights or interests by being offensive, annoying, dangerous, obstruc�  tive, or unhealthful. Such activities as obstructing a public road, polluting  air and water, operating a house of prostitution, or keeping explosives are  public nuisances and constitute criminal violations. A private nuisance is  an activity or condition (e.g., excessive noise, disagreeable odor) that  interferes with the use and enjoyment of one�s property and that may be  a cause of action in civil litigation. An attractive nuisance is something  on one�s property that poses a risk to children or others who may be  attracted to it.</p><p>Nujoma Vnu-'jo-moV Sam(uel Shafiihuma) (b.

In the late 1950s Nujoma helped found the Ovamboland Peo�  ple�s Organization, forerunner of the South West Africa People's Organi�  zation (SWAPO). He became SWAPO�s first president in 1960, and, after  years of petitioning the UN to compel South Africa to release control of  South West Africa, he authorized armed resistance (1966). In 1989, after  some 30 years in exile, he led SWAPO to victory in the UN-supervised  elections.</p><p>Nukualofa V.nu-kii-a-'lo-foX Town (pop., 1999 est.: 36,360), capital,  and chief port of Tonga. Located on the northern shore of Tongatapu  Island in the southern Pacific Ocean, it has a deep-draft harbour that is  protected by reefs. Commercial activities centre on the export of copra  and bananas. Landmarks include the 19th-century royal palace, a chapel,  and royal tombs.</p><p>Nullarbor Vno-lo-.boiA Plain Vast limestone plateau, southern Austra�  lia. It lies along the south coast of western South Australia and eastern  Western Australia, extending north from the Great Australian Bight to the  Great Victoria Desert. It occupies 100,000 sq mi (260,000 sq km) of gen�  erally flat surface in bedrock. The name Nullarbor is derived from the  Latin nullus arbor (�no tree�). The Nullarbor National Park preserves rare  vegetation and fauna. The plain has many limestone caves, including  Koonalda Cave, an archaeological site.

First enunciated in the Virginia  and Kentucky Resolutions (1798), it was expanded by John C. Calhoun in  response to the Tariff of 1828. Calhoun maintained that a state �interpo�  sition� could block enforcement of a federal law. The South Carolina leg�  islature agreed by passing the Ordinance of Nullification (1832),  threatening to secede if the federal government forced collection of the  1828 tariff duties. Pres. Andrew Jackson asserted the supremacy of the  federal government. The U.S. Congress passed a compromise tariff bill  reducing the duties but also passed the Force Bill, which authorized fed�  eral enforcement of the law. The South Carolina legislature rescinded its  ordinance, but the conflict highlighted the danger of nullification.</p><p>number Basic element of mathematics used for counting, measuring,  solving equations, and comparing quantities. They fall into several cat�  egories. The counting numbers are the familiar 1, 2, 3 ... ; whole num�  bers are the counting numbers and zero; integers are the whole numbers  and the negative counting numbers; and the rational numbers are all pos�  sible quotients formed by integers, including fractions. These numbers  can be symbolically represented by terminating or repeating decimals.  Irrational numbers cannot be represented by fractions of integers or repeat�  ing decimals and must be represented by special symbols such as V2, e,  and k. Together, the rational and irrational numbers constitute the real  numbers, which form an algebraic field (see field theory), as do the complex  numbers. While the counting numbers and rational numbers come about  as the means of counting, calculating, and measuring, the others arose as  means of solving equations. See also transcendental number.</p><p>number system Method of writing numerals to represent numbers.  The use of zero as a placeholder was the greatest advance in number sys�  tems. The most common system is the decimal system, in which 10 sym�  bols (the Hindu-Arabic numerals) denote multiples of powers of 10 by their  position relative to the decimal point. Computers have brought greater  awareness of the binary number system, in which two symbols, 0 and 1,  represent multiples of powers of 2.</p><p>number theory Branch of mathematics concerned with properties of  and relations among integers. It is a popular subject among amateur math�  ematicians and students because of the wealth of seemingly simple prob�  lems that can be posed. Answers are much harder to come up with. It has  been said that any unsolved mathematical problem of any interest more  than a century old belongs to number theory. One of the best examples,  recently solved, is Fermat's last theorem.</p><p>numerical analysis Branch of applied mathematics that studies meth�  ods for solving complicated equations using arithmetic operations, often  so complex that they require a computer, to approximate the processes of  analysis (i.e., calculus). The arithmetic model for such an approximation  is called an algorithm, the set of procedures the computer executes is called  a program, and the commands that carry out the procedures are called code.  An example is an algorithm for deriving n by calculating the perimeter  of a regular polygon as its number of sides becomes very large. Numeri�  cal analysis is concerned not just with the numerical result of such a pro�  cess but with determining whether the error at any stage is within  acceptable bounds.</p><p>numerical control (NC) Control of a system or device by direct input  of data in the form of numbers, letters, symbols, words, or a combination  of these forms. It is a principal element of computer-integrated manufac�  turing, particularly for controlling the operation of machine tools. NC is  also essential to the operation of modern industrial robots. The two basic  types of NC systems are point-to-point, in which a device is programmed  to perform a series of motions with fixed starting and stopping points, and  continuous-path, in which a point-to-point programmed device has suf�  ficient memory to be �aware� of its former actions and their results and  to act in accordance with this information.</p><p>numerology Use of numbers to interpret a person�s character or divine  the future. It is based on the assertion by Pythagoras that all things can be  expressed in numerical terms because they are ultimately reducible to num�  bers. Using a method analogous to that of the Greek and Hebrew alphabets  (in which each letter also represented a number), modern numerology  attaches a series of digits to an inquirer�s name and uses these, along with  the date of birth, to reveal the person�s true nature and prospects.</p><p>Numidia \nu-'mi-de-9\ Ancient country, North Africa, approximately  coextensive with modern Algeria. During the Second Punic War (see Punic</p><p>wars), its two great tribes divided, one supporting the Romans and the  other the Carthaginians. The tribal chief Masinissa was made king of  Numidia after the Roman victory in 201 bc. After the destruction of  Carthage, thousands fled to Numidia, which became a Roman province  in 46 bc. Its capital was Cirta, and the chief city was Hippo, which was  the see of St. Augustine. After its conquest by the Vandals in ad 429,  Roman civilization there declined rapidly; some pockets of native culture  survived, however, and even continued after the Arab conquest in the 8th  century.</p><p>Nun \'niin\ or Nu Oldest of the Egyptian gods and father of Re, the sun  god. Nun represented the dark, turbulent waters out of which the cosmos  was churned. Since it was believed that the primeval ocean continued to  surround the ordered cosmos, the creation myth was reenacted each day  as the sun rose from the waters. Nun was also thought to exist as subsoil  water and as the source of the annual flooding of the Nile.</p><p>Nun River \'nim\ River, southern Nigeria. Considered the direct con�  tinuation of the Niger River, it flows southwest to the Gulf of Guinea, at  Akassa. It was a trade route in the 19th century, when the Igbo kingdom  controlled commerce. Petroleum was discovered along the Nun in 1963,  and oil is piped from the oil fields along the Trans-Niger Pipeline.</p><p>Nunavut Vnii-no-.vihA Territory (pop., 2001: 26,745), north-central  Canada. Nunavut (Inuit: �Our Land�) is the result of Canada�s largest land  claim settlement, created to give the Inuit (see Eskimo), representing 85%  of its population, a greater voice in Canadian government. Occupying an  area of 772,000 sq mi (2,000,000 sq km), or one-fifth of Canada�s land-  mass, it comprises the central and eastern parts of the former Northwest  Territories, including Baffin and Ellesmere islands. Its capital is Iqaluit. The  area was settled by Inuit from 4500 bc to ad 1000. Vikings probably vis�  ited during the Middle Ages, but the first records of exploration are from  Martin Frobisher�s 1576 search for the Northwest Passage. The mainland  was explored by Englishman Samuel Heame in 1770-72. After passing  through British possession, it was transferred to Canada in 1870. In 1976  a political organization called for the creation of a territory to settle Inuit  claims in the Northwest Territories. The proposal was approved by the  Canadian government in 1993. Nunavut�s first elections were held in  February 1999, and the territory was inaugurated on April 1, 1999.</p><p>Nur al-HilmT Vnur-al-'hil-meV, Burhanuddin bin Muhammad</p><p>(b. 1911, Kota Bharu, Malaya�d.

The laws deprived Jews of German citizenship and forbade marriage or  sexual relations between Jews and �citizens of German or cognate blood.�  Supplementary decrees defined a Jew as a person with at least one Jew�  ish grandparent and declared that Jews could not vote or hold public office.</p><p>Nurnberg Rallies Massive rallies held by the Nazi Party in Nurnberg,  Ger., to showcase its power. After smaller rallies at party conventions in  1923 and 1927, the first large-scale rally was held in 1929 and featured  the nationalistic pageantry that marked subsequent annual rallies (1933�  38). Attended by hundreds of thousands of Nazis, the rallies were care�  fully staged to reinforce party enthusiasm with martial songs, massed  banners and flags, goose-step marches, torchlight processions, and lengthy  orations by Adolf Hitler and other Nazi leaders.</p><p>Nurnberg trials (1945�46) Trials of former Nazi Party leaders held in  Nurnberg, Ger. At the end of World War II, the International Military Tri�  bunal was established by the U.S., Britain, France, and the Soviet Union  to indict and try former Nazis as war criminals. The tribunal defined the  offenses as crimes against peace (planning and waging of war in viola�  tion of treaties), crimes against humanity (extermination, deportation, and  genocide), and war crimes. After 216 court sessions, 3 of the original 22  defendants were acquitted, 4 (including Karl Donitz and Albert Speer) were  sentenced to prison for terms of 10 to 20 years, 3 (including Rudolf Hess)</p><p>were sentenced to life imprisonment, and 12 (including Wilhelm Keitel,  Joachim von Ribbentrop, Alfred Rosenberg, Arthur Seyss-Inquart, and Julius  Streicher) were sentenced to death by hanging. Hermann Goring commit�  ted suicide before he could be executed, and Martin Bormann was con�  victed in absentia.</p><p>Nurse, Sir Paul M. (b. Jan. 25, 1949, Norwich, Norfolk, Eng.) Brit�  ish scientist. He earned a Ph.D. from the University of East Anglia in  1973 and was a professor at the University of Oxford from 1987 to 1993.  In 1996 he was named director general of the Imperial Cancer Research  Fund (now Cancer Research UK). In the mid-1970s he conducted research  on yeast and discovered the gene that regulates different phases of the cell  cycle. He later found the corresponding gene in humans. His work aided  in the understanding of cancer cell development. Nurse shared a Nobel  Prize with R. Timothy Hunt and Leland H. Hartwell in 2001.</p><p>nurse shark Only Atlantic species ( Ginglymostoma cirratum ) of 25  carpet shark species (family Orectolobidae). Yellow- or gray-brown,  sometimes with dark spots, it may grow to over 13 ft (4 m) long. It may  attack swimmers, especially when provoked, but is not related to the dan�  gerous gray nurse ( Odontaspis arenarius ), a sand shark.</p><p>nursery Place where plants are grown for transplanting, for use as  stocks for budding and grafting, or for sale. Nurseries produce and dis�  tribute woody and herbaceous plants, including ornamental trees, shrubs,  and bulb crops. While most nursery-grown plants are ornamental, the  nursery business also includes fruit plants and certain perennial vegetables  used in home gardens (e.g., asparagus, rhubarb). See also floriculture.</p><p>nursery rhyme Verse customarily told or sung to small children.  Though the oral tradition of nursery rhymes is ancient, the largest num�  ber date from the 16th, 17th, and (most frequently) 18th centuries. Appar�  ently most rhymes were originally composed for adults, many as popular  ballads and songs. The earliest known published collection is Tommy  Thumb�s (Pretty) Song Book (1744), including �Little Tom Tucker,� �Sing  a Song of Sixpence,� and �Who Killed Cock Robin?� The most influen�  tial collection was Mother Goose�s Melody (1781), including �Jack and  Jill,� �Ding Dong Bell,� and �Hush-a-bye Baby on the Tree Top.�</p><p>nursing Health-care profession providing physical and emotional care  to the sick and disabled and promoting health in all individuals through  activities including research, health education, and patient consultation.  Nursing gained recognition in the 19th century with the activities of Flo�  rence Nightingale. Many nurses have specialties (e.g., psychiatry, critical  care). Nurse-practitioners, clinical nurse specialists, nurse-anesthetists,  and nurse-midwives undertake tasks traditionally performed by physi�  cians. Nursing degrees go as high as the doctorate, and staff positions  include administration. In addition to health-care settings, nurses practice  in schools, the military, industry, and private homes. Community (public  health) nurses educate the public on topics such as nutrition and disease  prevention.</p><p>nursing home Facility for care (usually long-term) of patients who  are not sick enough to need hospital care but are not able to remain at  home. Historically, most residents were elderly or ill or had chronic irre�  versible and disabling disorders, and medical and nursing care was mini�  mal. Today nursing homes have a more active role in health care, helping  patients prepare to live at home or with a family member when possible.  They help conserve expensive hospital facilities for the acutely ill and  improve the prospects of the chronically disabled. However, quality of  care varies widely, and the potential for abuse exists.</p><p>Nusayriyyah See �Alawiyyah</p><p>Nut \'niit\ In Egyptian religion, a goddess of the sky. She represented the  vault of the heavens and was often depicted as a woman arched over the  earth god Geb. Nut was believed to swallow the sun in the evening and  to give birth to it again in the morning. She was sometimes portrayed as  a cow, the form she took to carry the sun god, Re, on her back to the sky.  On five days preceding the New Year, Nut gave birth successively to the  deities Osiris, Horus, Seth, Isis, and Nephthys.</p><p>nut Dry, hard, one-seeded fruit consisting of a kernel, usually oily, sur�  rounded by a hard or brittle shell that does not split open at maturity. Nuts  include chestnuts, filberts, and walnuts; but other so-called nuts are botani-  cally seeds (Brazil nut, pistachio), legumes (peanut), or drupes (almond and  coconut). Most edible nuts are well known as dessert nuts. Some nuts are  sources of oil or fat. Not all nuts are edible; some are used for ornament.</p><p>L_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1390 I nut &#x25BA; Nykvist</p><p>L_</p><p>N</p><p>nut In technology, a fastening device consisting of a square or hexago�  nal block, usually of metal, with a hole in the centre having internal, or  female, threads that fit on the male threads of an associated bolt or screw.

(9.5-19 cm)  long and have a short, square tail,  short neck, and thin, pointed bill.</p><p>Most are forest dwellers; some live in  rocky areas. Nuthatches search tree  trunks and rocks for insects, often  descending headfirst. They also eat  seeds, which they may store for win�  ter. The nest is a grass- or hair-lined  cavity. Nuthatches are most common  from Eurasia to Japan and south�  ward; four species occur in North  America. Most are bluish above and  white or reddish below; there may be a black eye stripe or a cap.</p><p>nutmeg Spice made from the seed of a tropical tree ( Myristica fra-  grans ), native to the Moluccas of  Indonesia. It has a distinctive pun�  gent fragrance and is used in cook�  ing and sachets and as incense. The  tree yields fruit eight years after sow�  ing, reaches its prime in 25 years,  and bears fruit for 60 years or longer.</p><p>The name nutmeg is also applied in  different countries to other fruits or  seeds, including the Brazilian nut�  meg ( Cryptocarya moschata ), the  Peruvian nutmeg ( Laurelia aromat-  ica ), and the California nutmeg ( Tor-  reya californica).</p><p>nutria or coypu Semiaquatic South American rodent {Myocastor coy-  pus) in the hutia family (Capromy-  idae). The nutria has small ears, a  long, rounded, scaly tail, partially  webbed hind feet, and broad orange  incisors. It is about 40 in. (1 m) long,  including the tail, and may weigh 18  lbs (8 kg). Its reddish brown fur con�  sists of coarse guard hairs overlying  a soft undercoat. The nutria lives in  a shallow burrow along a pond or  river and mainly eats aquatic plants.</p><p>Because their fur is valuable, nutrias  were introduced into North America  and Europe, and in some places have  become pests that damage crops and compete with other wildlife.</p><p>nutrition Processes of taking in and utilizing food substances. Food  generates energy and supplies materials used in body tissues and pro�  cesses. Calories are supplied by carbohydrates (sugars and STARCHes), fats,  and proteins. Other nutrients include minerals, vitamins, and dietary fibre.  Minerals are used in many ways� iron for hemoglobin; calcium for bones,  teeth, and cellular processes; sodium and potassium to regulate homeosta�  sis, iodine to produce thyroid hormones. Trace minerals have functions that  are less well-understood. Fibre is not broken down chemically in the body  but aids digestion, lowers blood cholesterol, and may help prevent some  cancers and hypertension. Diiferent amounts of these nutrients exist in dif�  ferent foods; a varied diet ensures an adequate supply. Nutritional supple�  ments, required by some people, do not compensate for an unhealthy diet.  Sufficient water is always essential. Inadequate nutrient intake or absorp�  tion leads to malnutrition and disease.</p><p>Nuuk \'niik\ or Godthab Vg6t-,h6p\ City (pop., 2000 est.: 13,838),  capital of Greenland. Located on the southwestern coast near the mouth  of Godthab Gulf, it is Greenland�s main port. The modern city dates from  1721, when a Norwegian missionary founded a colony near the site of  Vesterbygden, a 10th-century Norse settlement. It is the seat of the par�  liament and supreme court and has foreign consulates, a teachers� col�</p><p>lege, and research stations. Government administration, hunting, fishing,  and farming are the main occupations. Most transportation is by boat or  helicopter.</p><p>Nuwua or Nu Kua Vnui-'gwaV In Chinese mythology, the patroness  of matchmakers. As wife or sister of the legendary emperor Fuxi, she  helped establish norms for marriage (including the use of go-betweens)  and regulated conduct between the sexes. She is represented with a human  head and the body of a snake or fish. She repaired the pillars of the heav�  ens and the broken comers of the earth, which the rebel Gong Gong had  destroyed in a fit of anger, and her beautiful palace was said to be the  prototype for the walled cities of China.</p><p>Nyakyusa \nyak-'yu-s9\ or Ngonde \3q-'gon-da\ Bantu-speaking  people living north of Lake Malawi in Tanzania, and in Malawi. They  speak a Bantu language of the Niger-Congo family. Traditionally they  lived in unique age villages. All the boys of a district aged 11-13 would  leave their paternal homes and establish a new hamlet, eventually mar�  rying and bringing their wives there; their native village would die as its  founders died in old age. With modem land shortages, this practice has  largely stopped. The Nyakyusa, who are primarily hoe cultivators, num�  ber more than one million.</p><p>nyala \ne-'a-lo\ Slender antelope ( Tragelaphus angasi ) of South Africa  having a crest of hair along the back from head to tail and standing 3.5 ft  (110 cm). The male, which has loosely spiraled horns and a long fringe  on the throat and underparts, is dark brown with reddish brown on the  lower legs, white on the face and neck, and vertical white stripes on the  body. The female is reddish brown with more conspicuous striping.  Nyalas live alone or in small groups in forests. The rare mountain nyala  (T. buxtoni) of central Ethiopia is grayish brown.</p><p>Nyasa, Lake See Lake Malawi</p><p>Nyasaland See Malawi</p><p>Nyaya \'nya-ya\ One of the six darshans (orthodox systems) of Indian  philosophy, important for its analysis of logic and epistemology and for  its detailed model of the reasoning method of inference. Like other dar�  shans, Nyaya is both a philosophy and a religion; its ultimate concern is  to bring an end to human suffering, which results from ignorance of real�  ity. It recognizes four valid means of knowledge: perception, inference,  comparison, and testimony.</p><p>Nyerere \ni-'rar-e\ / Julius (Kambarage) (b. March 1922, Butiama,  Tanganyika�d. Oct. 14, 1999, Lon�  don, Eng.) First prime minister of  independent Tanganyika (1961), first  president of Tanzania (1964-85), and  the major force behind the Organiza�  tion of African Unity (OAU; now  African Union). He taught in Catho�  lic schools before studying history  and economics in Britain. As leader  of the Tanganyika African National  Union (TANU), he advocated peace�  ful change, social equality, and ethnic  harmony. In elections in 1958-60  TANU won many seats in the legis�  lature. As president he collectivized  village farmlands, carried out mass  literacy campaigns, and instituted  universal education. He sought to make Tanzania economically self-  sufficient, an effort that ultimately failed. In 1979 he authorized the inva�  sion of Uganda to overthrow Idi Amin. Within the OAU he advocated the  overthrow of white-suprematist governments in South Africa, Rhodesia,  and South West Africa. After retiring from politics in 1990, Nyerere  devoted the rest of his life to farming and diplomacy.</p><p>Nyiragongo V.nye-ra-'goq-goV, Mount Active volcano, Virunga  Mountains, east-central Africa. It lies in the volcano region of Virunga  National Park, eastern Congo (Kinshasa), near the border with Rwanda.

Best known for his subtle, luminous cam�  era work in a long series of Bergman films, he won Academy Awards for  Cries and Whispers (1972) and Fanny and Alexander (1983). With U.S.  directors, he shot movies such as The Unbearable Lightness of Being  (1988) and Crimes and Misdemeanors (1989).</p><p>nylon Any synthetic plastic material composed of polyamides of high  molecular weight and usually, but not always, manufactured as a fibre.  Nylons were developed by Du Pont in the 1930s. The successful produc�  tion of a useful fibre by chemical synthesis from compounds readily avail�  able from air, water, and coal or petroleum stimulated expansion of  research on polymers, leading to a rapidly growing family of synthetics.  Nylon can be made to form fibres, filaments, bristles, or sheets to be  manufactured into yarn, textiles, and cordage, and it can also be formed  into molded products. It has high resistance to wear, heat, and chemicals.  Most applications are in the form of filaments in such articles as hosiery,  parachutes, and outerwear. See also W. H. Carothers.</p><p>nymph In Greek mythology, any of a large class of minor female divini�  ties. Nymphs were usually associated with features of the natural world,  such as trees and water. Though not immortal, they were extremely long-  lived, and they tended to be well disposed toward humans. They were  grouped according to the sphere of nature with which they were con�  nected.</p><p>nymph In entomology, the sexually immature form of insects that  undergo incomplete metamorphosis (e.g., grasshoppers). The nymph is simi�  lar to the adult but differs in body proportions and (in winged species) has</p><p>only wing buds, which develop into wings after the first few molts (see  molting). During each successive growing stage (instar), the nymph begins  to resemble the adult more closely. The nymphs of aquatic species (also  called naiads), such as dragonflies, have gills and other modifications for  an aquatic existence. At maturity, they float to the surface or crawl out of  the water, undergo a final molt, and emerge as winged adults.</p><p>nymphaeum \nim-'fe-3m\ Ancient Greek and Roman sanctuary con�  secrated to water nymphs. Nymphaea also served as reservoirs and assem�  bly chambers for weddings. The name, originally denoting a natural grotto  with springs, later referred to an artificial grotto or building filled with  plants, sculpture, fountains, and paintings. Nymphaea existed at Corinth,  Antioch, and Constantinople, and remains have been found in Rome, Asia  Minor, Syria, and northern Africa.</p><p>Nymphenburg porcelain German hard-paste, or true, porcelain pro�  duced in Bavaria from the mid-18th century to the present day. Its fame  rests on its figures, particularly those in the Rococo style modeled between  1754 and 1763 by Franz Anton Bustelli (1723-1763). Tableware and  vases produced at the factory in Nymphenburg, on the outskirts of  Munich, often contain ozier, or basketwork, pattern borders.</p><p>Nyoro \'nyor-o\ or Bunyoro Bantu-speaking people of west-central  Uganda. Until the 18th century the Bunyoro kingdom included present-  day Uganda. It declined in the 18th and 19th century, surrendering its pre�  eminence to the Buganda kingdom. It was brought into the Uganda  Protectorate by the British. Today the Nyoro, numbering about 700,000,  live in scattered settlements and cultivate millet, sorghum, and plantains.</p><p>Nystad, Treaty of See Second Northern War</p><p>l_</p><p>M</p><p>N</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1392 I Oahu &#x25BA; obia</p><p>Oahu \6-'wa-hu\ Island (pop., 2000: 876,165) of Hawaii, U.S. Situated  between the islands of Kauai and Molokai, it occupies 607 sq mi (1,574  sq km) and is the third largest and most densely populated of the Hawai�  ian Islands. Of volcanic origin, it has two parallel mountain groups, the  Koolau Range and Waianae Ranges, which are connected by a central  plateau. It is the site of Honolulu, Pearl Harbor, and Waikiki. Military  installations, tourism, pineapples, and sugar are important to its economy.</p><p>oak Any of about 450 species of ornamental and timber trees and shrubs  that make up the genus Quercus in the beech family, found throughout  temperate climates. Oaks are deciduous trees that bear spring catkins (male  flowers) and spikes (female flowers) on the same tree. The leaves have  lobed, toothed, or smooth margins. The fruit is the acorn. They are  hardy and long-lived shade trees. White oaks have smooth  leaves and rapidly germinating sweet acorns; red, or black,  oaks have bristle-tipped leaves and bitter, hairy acorns.</p><p>Red- and white-oak lumber is used in construction,  flooring, furniture, millwork, barrel making, and the  production of crossties, structural timbers, and mine  props. The genus includes many ornamentals and  natural hybrids.</p><p>Oakland City (pop., 2000: 399,484), western  California, U.S., on the eastern side of San Fran�  cisco Bay. Settled by the Spanish in 1820, it was  incorporated as a city in 1854. In 1869 it was cho�  sen as the terminus of the first transcontinental rail�  road, which led to the development of its deepwater  port. It suffered damage and loss of life in the earth�  quake of 1989, which also damaged the Bay Bridge that  connects it with San Francisco. Lake Merritt, near the cen�  tral business district, is a wildfowl refuge surrounded by park�  land. Several colleges are located in Oakland.</p><p>Oakley, Annie orig. Phoebe Anne Moses (b. Aug. 13, 1860,  Darke county, Ohio, U.S.�d. Nov. 3, 1926, Greenville, Ohio) U.S. sharp�  shooter. As a child she won acclaim for her marksmanship. She later  toured vaudeville circuits with her marksman husband, Frank Butler. In  1885 they joined Buffalo Bill�s Wild West Show; she was one of the show�s  star attractions for most of the next 16 years. Oakley�s famous act included  shooting off the end of a cigarette held in Butler�s lips, hitting the thin  edge of a playing card from 30 paces, and shooting distant targets while  looking into a mirror. In 1887 she was presented to Queen Victoria, and  later in Berlin she performed her cigarette trick with, at his insistence.

Underground water sources account for most oases; their  springs and wells are supplied from sandstone aquifers whose intake areas  may be more than 500 mi (800 km) away. Two-thirds of the population  of the Sahara live in oases, where the date palm is the main source of food;  the palm also provides shade for growing citrus fruits, figs, peaches, apri�  cots, vegetables, and cereal grains.</p><p>Oates, Joyce Carol (b. June 16, 1938, Lockport, N.Y., U.S.) U.S.  writer. Oates taught at the University of Windsor (1967-78) and Prince�  ton University (from 1978). Beginning with the story collection By the  North Gate (1963) and the novel With Shuddering Fall (1964), she wrote  prolifically, often portraying people whose intensely experienced lives end  in bloodshed and self-destruction owing to forces beyond their control.  Her major novels include them (1969), Do with Me What You Will (1973),  Foxfire (1993), and Beasts (2002). Also significant is a parodic gothic  series including Bellefleur (1980), A Bloodsmoor Romance (1982), and  Mysteries of Winterthurn (1984).</p><p>Oates, Titus (b. Sept. 15, 1649, Oakham, Rutland, Eng.�d. July 12/13,  1705, London) English fabricator of the Popish Plot. Son of a Baptist  preacher, he was ordained in the Church of England. Although jailed for  perjury in 1674, he became chaplain to the Protestants in the household of  the Catholic 6th duke of Norfolk in 1677. In 1678, with the fanatically  anti-Catholic Israel Tonge, he invented the Popish Plot, a fictitious Jesuit  conspiracy to kill Charles II and place his Catholic brother James (later  James II) on the throne. Oates�s testimony caused some 35 persons to be</p><p>executed, but inconsistencies in his story emerged, and he was convicted  of perjury and imprisoned in 1685; released in 1688, he died in obscurity.</p><p>oats Hardy cereal plant (Avena sativa), cultivated in temperate regions,  that is able to live in poor soil. The edible starchy grain is used primarily  as livestock feed, but is also processed into rolled oats and oat flour for  human consumption.

It has faculties of arts, communica�  tions, foreign languages, law, letters, mathematics, psychology, public  service, science, and social sciences, as well as a music conservatory.</p><p>obesity Excessive body fat. It is usually caused by sedentary habits and  a diet high in fat, alcohol, or total calories. Calories consumed but not  used are stored as fat. Rare causes include glandular defects and excess  steroids (see Cushing syndrome). Obesity raises the risk of heart disease and  diabetes mellitus. Treatment, by reducing calorie intake and increasing exer�  cise, is best undertaken with a doctor�s advice.</p><p>obia or obeah Yo-be-a\ In West African folklore, a gigantic animal  that steals into villages by night to kidnap girls on behalf of witches.

It is a departure from traditional or proce�  dural programming. OOP languages incorporate objects that are self-  contained collections of computational procedures and data structures.  Programs can be written by assembling sets of these predefined objects  in far less time than is possible using conventional procedural languages.  OOP has become extremely popular because of its high programming  productivity. C++ and Objective-C (early 1980s) are object-oriented ver�  sions of C that have gained much popularity.

The bread and  wine offered for consecration in the Eucharist are oblations. In the Middle  Ages children dedicated to a monastery and left there to be brought up  were called oblates. Later, oblates were laity who lived at or in close con�  nection with a monastery but who did not take religious vows. Members  of certain Roman Catholic communities take the title oblate (e.g., the  Oblates Regular of St. Benedict).</p><p>oboe Double-reed woodwind instrument. The oboe developed out of the  more powerful shawm in the early 17th century. Intended (unlike the  shawm) for indoor use with stringed instruments, its tone was softer and  less brilliant. With its sweet but piercing sound, it was by the end of the  17th century the principal wind instrument of the orchestra and military  band and, after the violin, the leading solo instrument of the time. The  early oboe had only 2 keys, but in France by 1839 the number of keys  had gradually increased to 10. With the decline in popularity of the mili�  tary band, the oboe likewise declined somewhat in popularity. Today the  orchestra generally includes two oboes.

Little is known of his ori�  gins or education, but in 1484 he was appointed instructor of choirboys  at Cambrai cathedral and then held a position in Brugge. His composi�  tional style is notable for its warm, graceful melodies and clear harmo�  nies. Most outstanding are his 29 masses; he also wrote about 30 motets  and some secular music. Despite his contemporary renown, he had little</p><p>influence on later composers, since his works were not widely distributed  and his intellectual but exuberant music came to seem old-fashioned with  the advent of Josquin des Prez.</p><p>Obregon \,o-bra-'gon\, Alvaro (b.

A skillful  military leader who fought for the moderate presidents Francisco Madero  and Venustiano Carranza during the Mexican Revolution, he was largely  responsible for the liberal constitution of 1917. In response to Carranza�s  increasingly reactionary policies, Obregon took a leading role in the revolt  that deposed him and was himself elected president in 1920. He managed  to impose relative peace and prosperity on his war-torn country. He was  elected again in 1928 but was shot and killed before assuming office.</p><p>Obrenovic dynasty \6-'bren-3-,vet y \ Family that provided Serbia  with five rulers between 1815 and 1903.

The  Supreme Court of the United States has ruled that materials are obscene if  they appeal predominantly to a prurient interest in sexual conduct, depict  or describe sexual conduct in a patently offensive way, and lack serious  literary, artistic, political, or scientific value. Material deemed obscene  under this definition is not protected in the U.S. by the free-speech guar�  antee of the 1st Amendment.

Observatories can be classi�  fied by the part of the electromagnetic spectrum they can receive. Most are  optical, observing in and near the region of the visible spectrum. Some  are equipped to detect radio waves; others (space observatories) are Earth  satellites and other spacecraft that carry special telescopes and detectors  to study celestial sources of high-energy radiation (e.g., gamma rays, ultra�  violet radiation, X-rays) from above the atmosphere. Stonehenge may have  been an early predecessor of the optical observatory. Perhaps the first  observatory that used instruments to accurately measure the positions of  celestial objects was built c. 150 bc by Hipparchus. The first notable pre�  modern European observatory was that at Uraniborg, built for Tycho Brahe  in 1576. Observatory House, in Slough, Eng., built and operated by Wil�  liam Herschel (see Herschel family), was one of the technical wonders of  the 18th century. Today the world�s largest groupings of optical telescopes  are atop Mauna Kea, in Hawaii, and Cerro Tololo, in Chile. Other major  observatories include Arecibo Observatory; Mount Wilson Observatory;  Palomar Observatory; and Royal Greenwich Observatory.</p><p>obsessive-compulsive disorder Mental disorder in which an indi�  vidual experiences obsessions or compulsions, either singly or together.  An obsession is a persistent disturbing preoccupation with an unreason�  able idea or feeling (such as of being contaminated through shaking hands  with someone). A compulsion is an irresistible impulse to perform an irra�  tional act (such as repeatedly washing the hands). The two phenomena  are usually, but not always, linked in the obsessive-compulsive person.  Onset of the illness has been linked to malregulation of the neurotrans�  mitter serotonin as well as to the ill effects of high stress.</p><p>obsidian Natural glass of volcanic origin that is formed by the rapid  cooling of viscous lava. It has a glassy lustre and is slightly harder than  window glass. It is typically jet black, but the presence of hematite (iron  oxide) produces red and brown varieties, and tiny gas bubbles may cre�  ate a golden sheen. It is sometimes used as a semiprecious stone. Obsid�  ian was used by American Indians and others for weapons, implements,  tools, and ornaments, and by the ancient Aztecs and Greeks for mirrors.</p><p>obstetrics and gynecology \,gl-n9-'ka-l3-je\ Medical and surgical  specialty concerned with the management of pregnancy and childbirth and  with the health of the female reproductive system. Obstetrics, first practiced  by midwives, developed as a medical discipline in the 17th-19th centu�  ries, adopting the use of forceps in delivery, anesthetics, and antiseptic  methods. The last two made cesarean section possible. Obstetricians con�  firm pregnancy, diagnose ectopic pregnancy, conduct prenatal care, per�  form amniocentesis, deliver babies, and perform abortions. In the late 20th  century a backlash against the excessive medicalization of birth led to a  revival of midwifery and encouragement of natural childbirth. Gynecolo�  gists do routine pelvic exams, take samples for Pap smears, advise on and  prescribe birth control, and treat reproductive system disorders (e.g.,  endometriosis, hormonal imbalances, problems with menstruation and  menopause). They perform surgery to prevent conception (tubal ligation),  repair pelvic injuries, and remove cysts and tumours from the uterus, cer�  vix, and ovaries. Both specialties are involved in diagnosis and treatment  of INFERTILITY. See also HYSTERECTOMY.</p><p>Obuchi Vo-bu-cheV Keizo (b. June 25, 1937, Nakanojo, Japan�d.

March 30, 1880, Dublin,  Ire.�d. Sept. 18, 1964, Torquay, Devon, Eng.) Irish playwright. Born to</p><p>a poor Protestant family, he educated  himself and worked from age 14 at  manual labour. He embraced the  Irish nationalist cause, changed his  name to its Irish form, and became  active in the labour movement and  its paramilitary Irish Citizen Army.</p><p>By 1915 he had turned from politics  to writing realistic tragicomedies  about Dublin slum dwellers in war  and revolution. The Abbey Theatre  produced three of his earliest and  best plays� The Shadow of a Gun�  man (1923), Juno and the Paycock  (1924), and The Plough and the  Stars (1926)�which caused riots by  Irish patriots. When his antiwar play  The Silver Tassie was rejected by the  Abbey, O�Casey moved to England,  where it was produced in 1929. His  later plays include Red Roses for Me  (1946); he also published a six-volume autobiography (1939-56).</p><p>Occam, William of See William of Ockham  Occam's razor See Ockham's razor</p><p>occasionalism Type of mind-body dualism that maintains that appar�  ent interactions between mental and physical events are in reality the  result of God�s constant causal action. Starting from Descartes�s mind-  body dualism, the occasionalists, whose most prominent exponents were  Nicolas de Malebranche and Arnold Geulincx, drew the conclusions that  there can be no interaction between mind and body, and that all causality  is immanent, within one order or the other, and any appearance of mind  affecting body or of body affecting mind must be explained as the result  of a special intervention by God, who, on the occasion of changes in one  substance, produces corresponding changes in the other.</p><p>Occitan Vak-s9-,tan\ language or Provencal V.pro-.van-'sal,  ,pra-v3n-'sal\ language Romance language spoken in Occitania, a  region of southern France.

The term langue d�oc is based on the use of the word oc for �yes.�  The name Provengal originally referred to the dialects of the Provence  region, used by medieval troubadours and as a standard and literary lan�  guage in France and northern Spain in the 12th� 14th centuries. Today�s  major dialects are those of Limousin, Auvergnat, Provence, and Langue�  doc.

Occitan is  closely related to Catalan and, despite recent French influences, has more  in common with Spanish than with French.</p><p>occultism Theories, practices, and rituals based on esoteric knowledge  of the world of spirits and unknown forces. The wide range of occult  beliefs and practices includes astrology, alchemy, divination, magic, and  witchcraft and sorcery. Devotees of occultism seek to explore spiritual  mysteries through what they regard as higher powers of the mind. The  Western tradition of occultism has its roots in Hellenistic magic and  alchemy (especially the Hermetic writings ascribed to Thoth) and in the  Jewish mysticism associated with the Kabbala.</p><p>Occupation (of Japan) (1945-52) Military occupation of Japan by  the Allied Powers after its defeat in World War II. Theoretically an inter�  national occupation, in fact it was carried out almost entirely by the U.S.  under Gen. Douglas MacArthur. During the Occupation period, Japanese  soldiers and civilians from abroad were repatriated to Japan, arms indus�  tries were dismantled, and political prisoners were released. Wartime lead�  ers stood trial for war crimes, and seven were executed. A new constitution,  vesting power in the people, replaced the Meiji Constitution; in it Japan  renounced its right to wage war, the emperor was reduced to ceremonial  status, and women were given the right to vote. The Occupation admin�  istration also carried out land reform, reducing the number of farmers who  were tenants from 46% to 10%, and began the breakup of the zaibatsu  (business conglomerates). Labour unions were initially encouraged, but  as fears of leftist organizations grew with the advent of the Cold War,  stronger governmental control of labour was supported.

The Industrial Revolution�s long working hours, dim light, lack of fresh  air, and dangerous machinery fostered illness and injury in general, but  certain occupations (e.g., mining) carry particular risks (e.g., black lung,  a type of pneumoconiosis). Twentieth-century innovations (including use  of new chemicals and radioactive materials) caused an increase in certain  cancers (e.g.. leukemia and bone cancer in workers exposed to radiation)  and injuries. So-called �sick buildings� (in which pathogens grow in air  circulation systems) contribute to health problems among office workers.

Many were extraordinarily  luxurious. Among the most famous were Cunarders such as the Mauret�  ania and the Queen Mary, the German Vaterland (later renamed Levia�  than), for many years the largest ship afloat; the ill-fated Titanic, and the  United States. Their reign ended in the 1960s with the rise of jet travel,  but liners ranging from cruise ships to refrigerated cargo ships continued  to sail.</p><p>ocean perch See redfish</p><p>Oceania \,o-she-'a-ne-3\ Collective name for the islands scattered  throughout most of the Pacific Ocean. The term especially refers to islands  of the central and southern Pacific, including those of Micronesia, Melane�  sia, and Polynesia; New Zealand is often included and sometimes Austra�  lia. In its most restricted sense, excluding Australia but including Papua  New Guinea, Oceania includes more than 10,000 islands and has a land  area of about 317,000 sq mi (821,000 sq km). See map on following page.</p><p>Oceanic \,o-she-'a-nik\ arts Literary, performing, and visual arts of the  Pacific islands of Oceania, including Australia as well as Polynesia,  Melanesia, and Micronesia. Their isolation and wide range of environ�  mental conditions led to the development of a rich variety of artistic styles.  Religion and ritual strongly influence every aspect of Oceanic life, and  their association with the arts is especially close. Religious symbolism  infuses not only the objects, dances, and speeches used in ritual but also  the materials and tools used to create them. Oceanic literature includes  both complex oral traditions and a more modern body of works written  primarily in English. The traditional oral transmission of literature neces�  sitated rhythmic cadences and stock formulas to aid memory. Favoured  subjects are tales of the gods and spirits and creation myths. Musical styles  are multitudinous, though all regions, with some Melanesian exceptions,  emphasize vocals using instruments to produce supranormal voices. Con�  sequently most instruments are technically crude though often elaborately  decorated in keeping with their extramusical function as gifts and cult  objects.

In all the islands the significant movements are made with the  upper half of the body, while the feet merely keep time. The visual arts  display ingenious use of environmental possibilities: a staggering range  of materials are used, often in collage-style combination. Wood is the main  artistic medium; secondary materials included clay, shell, and stone.  Extant works include wooden masks, clubs, and religious effigies; carved  stone sculptures; feather cloaks and helmets; and bark cloth stenciled with  bold, dense geometric designs The most famous monuments of Oceanic  art are the gargantuan stone figures of Easter Island.

Tra�  ditional Melanesian religions, which are giving way under the pressures  of Christianity and capitalism, hold that ancestral ghosts and other spirits  are participants in daily life. Their presence and effects are manifested in  dreams, in divination, and in human successes and failures. Magic is  widely practiced, and sorcery is seen as the major cause of death and ill�  ness. The traditional religions of Micronesia, which have largely died out,  recognized several high gods and many other spirits, including the spirits  of ancestors and the dead. Magic played an important role. In Polynesia,  each of the gods, whether high or local, had its own ritual requirements,  and schools of priests were often required to carry them out. All things  were believed to possess mana, which had to be protected by complicated  rules and taboos. The Polynesians often offered human sacrifices on  important occasions, such as the formal investiture of a priest or chief.  With the introduction of modem goods, the peoples of all these islands  became susceptible to cargo cults.</p><p>oceanic ridge Continuous, submarine mountain chain extending  approximately 50,000 mi (80,000 km) through all the world�s oceans,  separating them into distinct basins.

Lateral ridges extend from islands on the axis of the  oceanic ridge to coasts of adjacent continents. The oceanic ridge system  is the largest feature of the Earth�s surface after the continents and the  ocean basins themselves; it is explained by the theory of plate tectonics  as a boundary between diverging plates where molten rock is brought up  from deep beneath the Earth�s crust.

May 15, 1847, Genoa, Kingdom of  Sardinia) Irish nationalist leader. A lawyer, he gradually became involved  in the struggle for Catholic Emancipation, organizing nationwide �aggre�  gate meetings� of Irish Catholics to petition for their legal rights. In 1823  he cofounded the Catholic Association, which won support from Irish  political and church leaders. After helping win passage of the 1829 Eman�  cipation Act, which allowed Irish Catholics to serve in the British Parlia�  ment, he was elected to the House of Commons. He supported the Whig  Party in return for Irish reform measures but became disenchanted with  the administration�s inaction. In 1839 he formed the Repeal Association  to dissolve the Anglo-Irish Act of Union. A series of illegal mass meet�  ings in Ireland led to his arrest for sedition in 1843. After his release in  1844, he faced dissension from William Smith O'Brien�s radical Young Ire�  land movement.</p><p>O'Connor, Feargus Edward (b. c. July 18, 1796, Connorville,  County Cork, Ire.�d.

He  turned to radical agitation in England and was active in the Chartist move�  ment as a popular public speaker. His journal Northern Star (1837) gave  his views wide circulation. He became the Chartists� leader in 1841 but  was unable to effect passage of the Chartist petition in 1848.

She spent most of  her life on her mother�s farm in Milledgeville, Ga. A devout Roman  Catholic, she usually set her works in the rural South and often examined  the relationship between the individual and God by putting her charac�  ters in grotesque and extreme situations. Her first novel. Wise Blood  (1952), combines a keen ear for common speech, a caustic religious  imagination, and a flair for the absurd that characterized all of her work.  With the story collections A Good Man Is Hard to Find (1955) and Every�  thing That Rises Must Converge (1965), she was acclaimed as a master  of the form. Her other work of fiction was the novel The Violent Bear It  Away (1960). Long crippled by lupus, she died at age 39.

He won popularity in the U.S. for short stories in which appar�  ently trivial incidents illuminate Irish life. They appeared in volumes  including Guests of the Nation (1931) and Crab Apple Jelly (1944) and  in The New Yorker magazine.

She served as an assistant state attorney general (1965-69) before  being elected in 1969 to the state senate, where she became the first  woman in the U.S. to hold the position of majority leader (1972-74). After  serving on the superior court of Maricopa county and the state court of  appeals, she was nominated in 1981 by Pres. Ronald Reagan to the Supreme  Court of the United States, becoming the first female justice in the court�s  history. Known for her dispassionate and meticulously researched opin�  ions, she proved to be a moderate and pragmatic conservative who some�  times sided with the court�s liberal minority on social issues (e.g., abortion  rights).

He brought the  domain of his birth, Owari, under his control and followed that success  by defeating the huge forces of a neighbouring daimyo. In 1562 he formed  an alliance with Ieyasu, and together they captured Kyoto, which  Nobunaga controlled from 1573, thereby ending the Ashikaga shogunate  (see Muromachi period). He then turned his attention to crushing the mili�  tant Tendai Buddhist monks of Enryaku temple, destroying their head�  quarters in 1571. He spent the next decade fighting the fanatically  religious Ikko sect, defeating their fortress-monastery in Osaka in 1580.  His efforts to weaken the strength of the Buddhist temples extended to  permitting Jesuit missionaries to build a church in Kyoto; his own inter�  est in Christianity was purely political. In 1582 he had conquered central  Japan and was attempting to extend his control over western Japan when  he was wounded by a discontented general and committed suicide.</p><p>ode Ceremonious lyric poem on an occasion of dignity in which per�  sonal emotion and universal themes are united.

He began writing longer operettas and had a string of hits, includ�  ing Orpheus in the Underworld (1858), La Belle Helene (1864), La Vie  Parisienne (1866), and The Grand Duchess of Gerolstein (1867). Offen�  bach is credited with writing in a fluent, elegant style and with a highly  developed sense of both characterization and satire.

With some 12,000 staff, the  OSS collected and analyzed information on areas of the world in which  U.S. military forces were operating. It used agents inside Nazi-occupied  Europe, including Berlin; carried out counterpropaganda and disinforma�  tion activities; produced analytical reports for policy makers; and staged  special operations (e.g., sabotage and demolition) behind enemy lines to  support guerrillas and resistance fighters.

The rubber cylinder gives great flexibility,  permitting printing on wood, cloth, metal, leather, and rough paper. In  offset printing the matter to be printed is neither raised above the surface  of the printing plate (as in letterpress printing) nor sunk below it (as in inta�  glio, or gravure, printing). Offset printing, a development of lithography,  is based on the principle that water and grease do not mix, so that a greasy  ink can be deposited on grease-treated printing areas of the plate, while  nonprinting areas, which hold water, reject the ink. The offset plate is  usually of zinc or aluminum or a combination of metals, with the surface  treated to render it porous and then coated with a photosensitive material.  Exposure to an image hardens the coating on printing areas; the coating  on nonprinting areas is washed away, leaving wetted metal that will reject  ink.

He spent a year in the U.S. learning American advertising techniques. In  1948, with Anderson Hewitt, he formed Hewitt, Ogilvy, Benson &amp;  Mather, which became one of the world�s largest advertising firms. He is  noted for reminding his colleagues that �the consumer is not a moron,�  and his ads for brands such as Schweppes and Rolls-Royce were admired  for their creativity.</p><p>Oglethorpe, James (Edward) (b.

After serving in the British army from 1712 to 1722, he entered Parlia�  ment, where he became interested in prison reform. In 1732 he secured a  charter for a colony in what became Georgia, where debtors could start a  new life and persecuted Protestants could practice freely. He accompa�  nied the first settlers to found Savannah (1733) and led the defense of the  territory against attacks by Spain (1739, 1742). He returned to England  in 1743.</p><p>Ogodei Vo-go-.daV (b. 1185, Mongolia�d. 1241, Karakorum) Son of  Genghis Khan who succeeded his father in 1229 and greatly expanded the  Mongol empire. He established his headquarters in central Mongolia and  built the capital city of Karakorum. Like his father, he carried out  simultaneous campaigns by relying on generals who acted independently  but were subject to his orders. Allying himself with China�s Southern  Song dynasty, Ogodei attacked the Juchen dynasty in northern China, tak�  ing its capital in 1234. Meanwhile, his nephew Batu defeated Russia while  other generals were attacking Iran and Iraq. Only Ogodei�s death (during  a drinking bout) prevented the Mongols from invading western Europe.

O�Hara developed the objective, straightforward style he used in his fic�  tion while working as a critic and reporter in New York City. His works  stand as a social history of upwardly mobile Americans of the 1920s  through the 1940s. Among them are the popular novels Appointment in  Samarra (1934); Butterfield 8 (1935; film, 1960); Pal Joey (1940),  adapted as a musical; Ten North Frederick (1955; film, 1958); and From  the Terrace (1958; film, 1960).</p><p>O'Higgins, Bernardo (b. probably Aug. 20, 1776/78, Chilian, Chile,  Viceroyalty of La Plata�d.

The illegitimate  son of a Spanish officer of Irish origin, he was educated in Peru, Spain, and  England, where his Chilean nationalism was awakened. When Napoleon  invaded Spain (1808) and Spanish control of Chile relaxed, he became a  member of Chile�s new congress. He led the defensive forces when Chile  was invaded by royalists from Peru in 1814; defeated, he fled to Argentina.  He returned in 1817 with Jose de San Martin and defeated the Spanish.  Elected supreme director of Chile, he established a working governmental  organization, but his reforms antagonized conservatives and he resigned.</p><p>Ohio State (pop., 2000: 11,353,140), U.S., north-central region. Bor�  dered by Michigan, Pennsylvania, West Virginia, Kentucky, and Indiana,  it covers 44,828 sq mi (116,104 sq km). Its capital is Columbus. Lake Erie  is on its northern boundary; the Ohio River forms part of its southeastern  and southern boundary. Ohio was originally inhabited by prehistoric</p><p>Hopewell mound builders, who disappeared c. ad 400. The earliest Euro�  pean explorers found the area occupied by Miami, Shawnee, and other  Indian peoples. The region was ceded to Britain by France after the French  and Indian War. In 1803 it became the 17th state and the first state carved  out of the Northwest Territory (see Northwest Ordinances). During the  19th century, it became one of the first great industrial states because of  its location, transport facilities, and natural resources, including coal,  petroleum, and natural gas. Although manufacturing is its most important  economic activity, nearly two-thirds of the state is still farmland. It was  the birthplace or residence of eight U.S. presidents� William H. Harrison,  Ulysses S. Grant, Rutherford B. Hayes, James Garfield, Benjamin Harrison,  William McKinley, William H. Taft, and Warren G. Harding. Its major cit�  ies include Columbus, Cleveland, Cincinnati, Toledo, Akron, and Dayton.</p><p>Ohio Co. Organization of Englishmen and Virginia colonists, estab�  lished in 1748 to promote trade with American Indians and secure Brit�  ish control of the Ohio River valley for settlement.

In 1827 Georg Simon  Ohm discovered that at constant temperature, the current I in a circuit is  directly proportional to the potential difference V, and inversely propor�  tional to the resistance R, or I = V/R. Resistance is generally measured in  ohms (�2). Ohm�s law may also be expressed in terms of the electromo�  tive force E of an electric energy source, such as a battery, or E = IR.

It may be a fixed (nonvolatile) oil, an essential oil, or a mineral oil  (see petroleum). Fixed oils and fats (derived from animals and plants) have  the same chemical composition�both are esters of glycerol and fatty acids.  These oils have a variety of industrial and food uses. Linseed, tung, and  other drying oils are highly unsaturated (see saturation); these and large  quantities of soybean, sunflower, and safflower oils (also constituents of  foods) are used in paints and varnishes. When exposed to air they absorb  oxygen and polymerize (see polymerization), forming a tough coating.  Some specialty oils and oil derivatives are also used in leather dressing  and textile manufacture.</p><p>oil-drop experiment See Millikan oil-drop experiment</p><p>oil painting Painting in oil colours, a medium consisting of pigments  suspended in drying oils. Oil paint enables both fusion of tones and crisp  effects and is unsurpassed for textural variation. The standard consistency  of oil paint is a smooth, buttery paste. It is applied with brushes or a thin  palette knife, usually onto a stretched linen canvas. Finished oil paintings  are often coated with varnish. Oil as a painting medium is recorded as  early as the 11th century, though the practice of easel painting with oil  colours stems directly from 15th-century techniques of painting with tem�  pera (see tempera painting). In the 16th century oil colour emerged as the  basic painting material in Venice; it has been the most widespread medium  for easel paintings ever since.</p><p>oil seal or shaft seal In machines, a device that prevents the passage  of fluids along a rotating shaft. Seals are necessary when a shaft extends  from a housing (enclosure) containing oil, such as a pump or a gearbox.  Leather, synthetic rubber, and silicones are among the materials used for  the sealing ring. See also bearing.</p><p>oil shale Any fine-grained sedimentary rock that contains solid organic  matter (kerogen) and yields significant quantities of oil when heated. This  shale oil is a potentially valuable fossil fuel, but the present methods of  mining and refining it are expensive, damage the land, pollute the water,  and produce carcinogenic wastes. Thus, oil shale will probably not be  exploited on a wide scale until other petroleum resources have been nearly  depleted.

The people�s name, spelled Ojibwe  in Canada and given as Chippewa in official U.S. documents, is derived  from an Algonquian word ojib-ubway, meaning �puckering,� probably  referring to a type of moccasin. They call themselves Anishinaabe or  Anishinabek, meaning �Spontaneously Created� or �Original Man.� They  formerly inhabited a region north of the Great Lakes but during the 17th�  18th centuries moved west to what is now northern Minnesota. Each  Ojibwa tribe was divided into migratory bands. In the autumn, bands  separated into family units for hunting; in summer, families gathered at  fishing sites. They grew corn and collected wild rice. The Midewiwin, or  Grand Medicine Society, was the major Ojibwa religious organization.  The Ojibwa are one of the largest Native American groups in North  America today, numbering about 50,000 in the U.S. and more than  100,000 in Canada. They are closely related to the Ottawa and Pota-  watomi.</p><p>Ojukwu \o-'juk-wii\, Odumegwu (b.

A member of the Igbo, Ojukwu was edu�  cated at Oxford University. He was appointed head of the traditional Igbo  homelands in the east following the overthrow of Nigeria�s civilian gov�  ernment by Igbo military leaders. He stayed on in that capacity even after  members of the opposition Hausa and Yoruba staged a successful coun�  tercoup.

The largest island in the Ryukyu chain, it  is about 70 mi (112 km) long and 7 mi (11 km) wide, with an area of 463  sq mi (1,199 sq km). It was the site of severe fighting between the U.S.  and Japan in World War II. In April 1945 U.S. troops made an amphibi�  ous landing on Okinawa, which was heavily defended by the Japanese.  In a three-month-long campaign, both sides sustained heavy casualties  before U.S. forces gained control of the island. In 1972 the United States  returned jurisdiction over Okinawa to Japan, though U.S. military instal�  lations remained.</p><p>Oklahoma State (pop., 2000: 3,450,654), southwest-central U.S. Bor�  dered by Colorado, Kansas, Missouri, Arkansas, Texas, and New Mexico,  it covers 69,898 sq mi (181,035 sq km). Its capital is Oklahoma City. The  Red River forms its southern boundary; the Arkansas River flows across  northeastern Oklahoma. Its highest point is Black Mesa (4,973 ft [1,516  m]), located in the Panhandle. Evidence of inhabitation by the Clovis and  Folsom cultures 15,000-10,000 years ago has been found. Until the expe�  dition of Francisco Vazquez de Coronado in 1541, the area was home to  representatives of at least three major Indian language groups. Spanish  control of the area lasted until 1800, when it passed to the French. In 1803  the area became part of the U.S. with the Louisiana Purchase. In 1828 the  U.S. Congress reserved Oklahoma for settlement by Indians, and it  became known as Indian Territory. In 1890 the western part was organized  as Oklahoma Territory. The two were merged and admitted to the union  as the 46th state in 1907. Cattle raising and farming are the mainstays of  the economy. Mineral products include natural gas, petroleum, coal, and  stone. The state�s heritage is reflected in Indian and cowboy museums.

It expanded rapidly  after the discovery of petroleum in the area in 1928. The largest city in  the state and its main commercial, financial, industrial, and transportation  centre, it is the chief marketing and processing point for the livestock  industry. It is home to the National  Cowboy Hall of Fame, Myriad Gar�  dens, and an annual rodeo competi�  tion. In 1995 it was the site of a  deadly act of domestic terrorism,  when the Alfred P.

It was rebuilt by Pisan colonists  in 1198 and named Terranova Pausania. Renamed Olbia in 1939, it is the  main passenger port for connections with the Italian mainland. It has  Phoenician and Roman ruins.</p><p>Old Believers Russian dissenters who refused to accept liturgical  reforms imposed on the Russian Orthodox Church by Nikon in 1652-58.  Numbering in the millions in the 17th century, the Old Believers endured  persecution for years, and several of their leaders were executed. They  split into a variety of sects, of which the two main groups were the Pop-  ovtsy (priestly sects) and Bezpopovtsy (priestless sects). In 1971 the coun�  cil of the Russian Orthodox Church rescinded all the anathemas of the  17th century and recognized the full validity of the old rites.</p><p>Old Catholic church Any of a group of Western Catholic churches  that separated from Rome after the First Vatican Council promulgated the  doctrine of papal infallibility (1869-70). Old Catholic churches in the Neth�  erlands, Germany, Switzerland, Austria, Poland, and elsewhere joined  together in 1889 to form the Union of Utrecht. The Old Catholics accept  the Bible, the Apostles� and Nicene creeds, and the seven sacraments. Their  chief authority in church government is the conference of bishops. They  have long used the vernacular in public worship; confession to a priest is  not obligatory, and in some Old Catholic churches the celibacy of the  clergy is optional.</p><p>Old Church Slavonic language or Old Church Slavic lan�  guage Oldest attested Siavic language, known from a small corpus of  10th- or 11th-century manuscripts, most written in the Glagolitic alpha�  bet (see Cyrillic alphabet). The Old Church Slavonic documents, all trans�  lations from Christian ecclesiastical texts, resulted from the mission to  the Moravian Slavs of Saints Cyril and Methodius, though all but one of  the surviving manuscripts were actually copied in South Slavic-speaking  areas. Beginning in the 11th century, the influence of the vernacular lan�  guages in cultural focal areas (Serbia, Bulgaria-Macedonia, Ukraine, and  Russia) led to regional variations in Church Slavonic. It remained the lit�</p><p>erary language of Eastern Orthodoxy in South Slavic and East Slavic lands  into modem times and is still the liturgical language of Slavic Orthodoxy  and the Slavic Eastern rite church.</p><p>Old English or Anglo-Saxon Language spoken and written in  England before ad 1100. It belongs to the Anglo-Frisian group of Ger�  manic languages. Four dialects are known: Northumbrian (in northern  England and southeastern Scotland), Mercian (central England), Kentish  (southeastern England), and West Saxon (southern and southwestern  England). Mercian and Northumbrian are often called the Anglian dia�  lects. Most extant Old English writings are in the West Saxon dialect. The  great epic poem of Old English is Beowulf ; the first period of extensive  literary activity occurred in the 9th century. Old English had three gen�  ders (masculine, feminine, neuter) for nouns and adjectives; nouns, pro�  nouns, and adjectives were also inflected for case. Old English had a  greater proportion of strong (irregular) verbs than does Modem English,  and its vocabulary was more heavily Germanic. See also Middle English;  Engush language.</p><p>Old English script See black letter script</p><p>Old English sheepdog Shaggy working dog developed in early 18th-  century England and used primarily to drive sheep and cattle to market.  It has a shuffling, bearlike gait and a dense, solid-coloured or white-  marked gray or blue-gray coat. It stands 21-26 in. (53-66 cm) tall and  weighs over 55 lb (25 kg). Its long, dense, weather-resistant coat covers  the eyes but does not obscure vision. The tail is usually removed soon  after birth.</p><p>Old Farmer's Almanac See Farmer's Almanac  Old Ironsides See USS Constitution</p><p>Old Norse language Classical Germanic language used c. 1150�  1350, the literary language of the Icelandic sagas, skaldic poetry, and  Eddas. The terms Old Norse and Old Icelandic are sometimes used inter�  changeably because Icelandic records of this period are more plentiful and  of greater literary value than those in the other Scandinavian languages,  but Old Norse also embraces the ancestors of modern Norwegian, Dan�  ish, Swedish, and Faroese.</p><p>Old Point Comfort Historic point and part of the city of Hampton,  southeastern Virginia, U.S. It is located at the entrance to Hampton Roads,  opposite Norfolk. Named by the colonists of Jamestown in 1607, it has  been the site of fortifications, including Fort George and Fort Monroe,  since 1609. The latter was a Union base during the American Civil War. It  was a popular seaside resort in the 19th and early 20th centuries.</p><p>Old Testament Sacred scriptures of Judaism and, with the New Testa�  ment, of Christianity. Written almost entirely in the Hebrew language  between 1200 and 100 bc, the Old Testament (also called the Hebrew  Bible or Tanakh) is an account of God�s dealings with the Hebrews as his  chosen people. In the Hebrew Bible, the first six books tell how the Isra�  elites became a people and settled in the Promised Land, the following  seven books describe the development of Israel�s monarchy and the mes�  sages of the prophets, and the last 11 books contain poetry, theology, and  some additional historical works. Christians divided some of the original  Hebrew books into two or more parts, specifically, Samuel, Kings, and  Chronicles (two parts each), Ezra-Nehemiah (two separate books), and  the Minor Prophets (12 separate books). The content of the Old Testa�  ment varies according to religious tradition, the Jewish, Roman Catholic,  and Protestant canons all differing from each other as to which books they  include. See also Apocrypha, Bible.</p><p>Old Vic London theatre company. The company�s theatre opened in  1818 as the Royal Coburg; renamed the Royal Victoria in 1833, it became  popularly known as the Old Vic. The company, managed by Lilian Baylis,  began a regular Shakespeare season in 1914. From the 1930s it was noted  for its memorable productions of Shakespeare�s plays and other classics,  with actors such as John Gielgud, Laurence Olivier, and Ralph Richardson.  The company was dissolved in 1963 and formed the nucleus of the new  National Theatre, which performed at the Old Vic theatre until moving to  a new building in 1976.</p><p>Old World monkey Any of some 100 species of monkeys (the catar-  rhine [�downward-nosed�] monkeys) that live in Africa, on the Red Sea  coast of Arabia, and in Asia from Afghanistan to Indonesia. Catarrhines  generally have a narrow nose, a narrow septum, close-set nostrils directed  forward or down, bony ear passages, two premolars in each half of each</p><p>Olaf V, 1973</p><p>KNUDSENS FOTOSENTER</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Oldenbarnevelt &#x25BA; Oliver I 1405</p><p>jaw, a nonprehensile tail (if any), and hard patches of bare skin (ischial  callosities) on the buttocks. Zoologists gather all Old World monkeys into  a single family, Cercopithecidae. There are two subfamilies: Cercopith-  ecinae, or monkeys with cheek pouches (macaques, baboons, vervets, man�  drills, and others); and Colobinae, or leaf monkeys (langurs, colobus  monkeys, proboscis monkeys, and others).

Dutch statesman and a founding father of Dutch independence. A  lawyer in the province of Holland, he helped William I negotiate the Union  of Utrecht (1579). Appointed �great pensionary� of Holland, he mobilized  Dutch resources for the military goals of Maurice of Nassau. As foreign  secretary of the Union�s seven provinces, he negotiated a triple alliance  with France and England against Spain (1596). He later concluded the  Twelve Years� Truce with Spain (1609), which reaffirmed Holland�s domi�  nant role in the republic. In 1617 he sided with the moderate Arminians  in religious strife against the stricter Calvinists (known as Counter-  Remonstrants) and Prince Maurice; he was arrested in 1618, convicted of  religious subversion, and beheaded.</p><p>Oldenburg Former German state, since 1946 part of Lower Saxony,  Germany. It was held by the counts of Oldenburg from c. 1100 until 1667,  when it passed to Denmark. In the late 18th century it was ruled by the  bishop of Liibeck, who was made duke of Oldenburg by Joseph II, the Holy  Roman emperor. It became a grand duchy in the early 19th century and  took Prussia�s side in the Austro-Prussian War of 1866. It joined the Ger�  man Empire in 1871. Its last grand duke abdicated in 1918. The 17th-  century grand-ducal palace in the city of Oldenburg (pop., 2002 est.:  155,908) is now a state museum of art and culture.</p><p>Oldenburg, Claes (Thure) (b. Jan. 28, 1929, Stockholm, Swed.)  Swedish-born U.S. Pop art sculptor. The son of a consular official, he spent  part of his early life in the U.S. He graduated from Yale University and  attended the Art Institute of Chicago before doing freelance illustrations  for magazines. He turned to sculpture after moving to New York City in  1956. Like other practitioners of Pop art, he chose banal subjects from  consumer culture, but for �soft sculptures� such as Giant Clothespin  (1976) and Giant Soft Shuttlecock (1995) he chose subjects with close  human associations. His frequent use of soft, yielding vinyl gave the  objects human, often sexual overtones.</p><p>Oldowan Yal-da-wsnX industry Stone-tool industry of the early Pale�  olithic (beginning c. 2.5 million years ago) characterized by crudely  worked pebble tools. Oldowan tools, made of quartz, quartzite, or basalt,  are chipped in two directions to form simple, rough implements for chop�  ping, scraping, or cutting. The industry is associated with early hominids,  such as Homo habius and possibly also Australopithecus robustus, and has  been found at Olduvai Gorge (from which its name derives), Lake Tur-  kana (see Lake Turkana remains), and the Afar region of Ethiopia. Oldowan  tools were made for nearly 1.5 million years before the emergence of the  Acheulean industry.</p><p>Olduvai Vol-do-.vl, 'ol-do-.waV Gorge Archaeological site on the east�  ern Serengeti Plain, northern Tanzania. It is a steep-sided ravine about 30  mi (48 km) long and 295 ft (90 m) deep. Deposits exposed in the sides  of the gorge cover a time span from c. 2,100,000 to 15,000 years ago and  have yielded the remains of more than 50 hominins as well as the most  complete sequence of stone tool industries. The site first came to public  notice in 1959 when Louis and Mary Leakey (see Leakey family) uncov�  ered the first specimens of Paranthropus, a hominin related to Australo�  pithecus. Remains of Homo habius. Homo erectus, and Homo sapiens have  since been found. These discoveries have strengthened the argument that  the human lineage originated in Africa. See also stone tool industry; Old�  owan INDUSTRY.</p><p>oleander Vo-le-.an-dsrV Any of the ornamental evergreen shrubs of the  genus Nerium (dogbane family), which have poisonous milky juice.  Numerous varieties of flower colour in the common oleander, or rosebay  ( N . oleander), have been introduced from greenhouse culture and are  grown outdoors in warmer climates. All parts of the plant are very toxic  if eaten, and contact with them may cause skin irritation.</p><p>oleaster family Vo-le-.as-torV Family Elaeagnaceae, composed of  three genera of hardy shrubs and small trees, found in the Northern Hemi�  sphere, especially in steppe and coastal regions. The plants� tiny, distinc�  tive scales give them a silvery or rust-coloured sheen. Many members of</p><p>the family perform nitrogen fixation. The berries of several species are  edible. Ornamental shrubs in this family include buffalo berry or silver-  berry ( Shepherdia argentea), oleaster or Russian olive {Elaeagnus angus-  tifolia), and sea buckthorn (Hippophae rhamnoides).</p><p>olefin Yo-la-fanV or alkene Any unsaturated hydrocarbon containing  one or more pairs of carbon atoms linked by a double bond (see covalent  bond, saturation). Olefins may be classified by whether the double bond  is in a ring (cyclic) or a chain (acyclic, or aliphatic) or by the number of  double bonds (monoolefin, diolefin, etc.). Rare in nature, olefins are  obtained by the cracking of petroleum fractions at high temperatures. The  simplest ones (ethylene, propylene, butylene, butadiene, and isoprene) are  the basis of the petrochemicals industry. They react by adding other chemi�  cal agents at the double bond to form derivatives or polymers.</p><p>Olga, Saint or Saint Helga (b. c. 890�d. 969, Kiev; feast day July  11) Princess of Kiev. The first recorded female ruler in Russia, she served  as regent of Kiev (945-964) after the assassination of her husband Igor I  (8777-945); she avenged his death by having his murderers scalded to  death. Probably baptized (c. 957) at Constantinople, she became the first  member of the ruling family of Kiev to adopt Christianity. She was can�  onized as the first Russian saint of the Orthodox church.</p><p>oligarchy Va-li-.gar-ke, 'o-li-.gar-keV Rule by the few, often seen as  having self-serving ends. Aristotle used the term pejoratively for unjust  rule by bad men, contrasting oligarchy with rule by an aristocracy. Most  classic oligarchies have resulted when governing elites were recruited  exclusively from a ruling class, which tends to exercise power in its own  interest. The term is considered outmoded today because �few� conveys  no information about the nature of the ruling group.</p><p>Oligocene Va-li-go-,sen\ Epoch Major division of the Tertiary Period,  from c. 33.7 to 23.8 million years ago. It follows the Eocene Epoch and  precedes the Miocene Epoch. The term (from the Greek for �few recent  forms�) refers to the small number of modem animals that originated dur�  ing this epoch. Oligocene climates appear to have been temperate, and  many regions were nearly tropical. Grasslands expanded, and forested  regions dwindled. The vertebrates of the northern continents had an essen�  tially modern aspect that is a result less of the appearance of new forms  than of the extinction of archaic vertebrates at the close of the Eocene.</p><p>oligopoly \,al-3-'ga-p3-le\ Market situation in which producers are so  few that the actions of each of them have an impact on price and on com�  petitors. Each producer must consider the effect of a price change on the  others. A cut in price by one may lead to an equal reduction by the oth�  ers, with the result that each firm will retain about the same share of the  market as before but with a lower profit margin. Competition in oligop�  olistic industries thus tends to manifest itself in nonprice forms such as  advertising and product differentiation. Oligopolies in the U.S. include  the steel, aluminum, and automobile industries. See also cartel, monopoly.</p><p>oligosaccharide \ 1 a-li-go- , sa-k9- 1 rId\ Any carbohydrate with a few  (between 3 and about 6 to 10) units of simple sugars (monosaccharides).  A wide variety of oligosaccharides are made by partially breaking down  polysaccharides. Most of the few naturally occurring oligosaccharides are  found in plants; those in animals tend to be combined in glycoproteins.</p><p>olive Subtropical, broad-leaved tree ( Olea europaea) or its edible fruit.  The olive was being grown on the island of Crete c. 3500 bc, and Semitic  peoples apparently were cultivating it as early as 3000 bc. Its cultivation  was important to the ancient Greeks and Romans and spread to all the  countries bordering the Mediterranean. Today olives are grown primarily  for olive oil, valued both for its distinctive taste and fragrance and for its  dietary benefits. Fresh olives must be treated to neutralize their extreme  bitterness before they can be eaten. The olive family (Oleaceae) comprises  about 900 species in 24 genera of woody plants. Native to forested  regions, members of the family grow worldwide except in the Arctic; they  are evergreen in tropical and warm temperate climes and deciduous in  colder zones. The family includes ash trees, which yield hardwood tim�  ber, and horticultural favourites such as the lilac, jasmine, privet, and for-  sythia. Many members of the family are cultivated for their beautiful and  fragrant flowers.</p><p>Oliver, King orig. Joseph Oliver (b. May 11, 1885, Abend, La.,  U.S.� d. April 8, 1938, Savannah, Ga.)

Frequently men�  tioned in the Bible, it is holy both in Judaism and in Christianity. Politi�  cally it is part of the municipality of Greater Jerusalem under Israeli  administration. Its slopes have been the most sacred burial ground in  Judaism for centuries. The peak generally regarded as the Mount of Olives  is 2,652 ft (808 m) in elevation. Nearby is the site held by tradition to be  the Garden of Gethsemane, which is associated with the betrayal and Cru�  cifixion of Jesus.</p><p>Olivetti &amp; C. SpA \,a-l9-'ve-te\ Historic Italian electronics and tele�  communications company. Founded in 1908 by Camillo Olivetti (1868�  1943), the firm began by making typewriters. Camillo�s son Adriano  studied manufacturing and plant management in the U.S. in the 1920s,  and as company president from 1938 made Olivetti into Europe�s prin�  cipal maker of business machines. The company later produced calcula�  tors, microcomputers, and copiers. In 1982 its U.S. subsidiary was  purchased by Docutel Corp. In the late 1990s Olivetti sold off its money�  losing computer business and remade itself as a telecommunications com�  pany with holdings in mobile and fixed-line telephones. It became a  subsidiary of Telecom Italia in 1993.</p><p>Olivier \3-'li-ve-,a\, Laurence (Kerr), Baron Olivier (of Brigh�  ton) (b. May 22, 1907, Dorking, Surrey, Eng.�d. July 11, 1989, near  London) British actor, director, and producer. He began his professional  career in 1926 and joined the Old Vic company in 1937, playing many  major Shakespearean roles. With Ralph Richardson he codirected the Old  Vic (1944-50), and he acted in some of its greatest productions, includ�  ing Richard III, Henry IV, and Oedipus Rex. He was knighted in 1947.  From 1950 he directed and acted under his own management; his notable  productions included Antony and Cleopatra and The Entertainer (1957).  He was the founding director of the National Theatre (1962-73), one of  whose theatres is now named for him. In 1970 he was created a life peer,  the first actor ever to be so honoured. His many films include Wuthering  Heights (1939), Rebecca (1940), Hamlet (1948, Academy Award), The  Entertainer (1960), and Othello (1965). He was married to the actresses  Vivien Leigh and (from 1961) Joan Plowright (b. 1929).</p><p>olivine Va-ta-.venX Any member of a group of common magnesium, iron  silicate minerals. Olivines occur in many igneous rocks and are a major  constituent of the Earth�s upper mantle. They also have been found in some  lunar rocks and in many meteorites. Olivine forms yellow to greenish yel�  low crystals and is sometimes used in making bricks. Transparent green  olivine (precious olivine) is called peridot.</p><p>Olmec \'al-,mek\ First elaborate pre-Columbian culture of Mesoamer-  ica. The Olmec lived in the lowland gulf coast of what is now southern  Mexico. Developing a wide trading network, their cultural influence  spread north to the Valley of Mexico and south to Central America; later  native religions and iconography throughout Mesoamerica have Olmec  roots. Their oldest known building site, San Lorenzo, which dates to c.  1150 bc, is remarkable for its colossal stone sculptures of human heads.  The dominant motif in Olmec art is the figure of a god that is a hybrid of  a jaguar and a human infant. Olmec buildings, monuments, and art style  all indicate a complex and nonegalitarian society.</p><p>Olmsted, Frederick Law (b. April 26, 1822, Hartford, Conn.,  U.S.�d. Aug. 28, 1903, Brookline, Mass.) U.S. landscape architect. He  traveled throughout the American South in the 1850s and won fame for  several books describing its slaveholding culture. During an extended  vacation in Europe, he became profoundly impressed with English land�  scaping, which he described in Walks and Talks of an American Farmer  in England (1852). In 1857 he was hired as superintendent of New York  City�s newly planned Central Park. With the architect Calvert Vaux (1824-  95), he won a competition to design the park, and he became its chief  architect in 1858. The result was a nature-lover�s paradise incorporating  lawns, woods, ponds, and meandering paths; it represented one of the first  attempts in the U.S. to apply art to the improvement of nature in a public  park. Other Olmsted parks include Prospect Park in Brooklyn, New York  City; a Niagara Falls, N.Y., park project; an extensive system of parks  and parkways in Boston; and the World�s Columbian Exposition (later  Jackson Park) in Chicago. As chairman of the first Yosemite commission,  he helped secure the area as a permanent public park.</p><p>Olmutz Vol-muits\, Punctation of (Nov. 29, 1850) Agreement signed  at Olmutz (now Olomouc, Cz.Rep.) between Prussia and Austria. In  response to an appeal from the elector of Hesse for help against rebellious  subjects, Prussia and Austria sent troops. They threatened to clash, and  when Russia sided with Austria, Prussia withdrew. In the Olmutz agree�  ment, Prussia gave up its plans to create a union of German states with�  out Austria and accepted Austria�s reconstitution of the German  Confederation. Prussia resented the diplomatic reverse and considered  itself humiliated.</p><p>Olney, Richard (b. Sept. 15, 1835, Oxford, Mass., U.S.�d. April 8,  1917, Boston, Mass.) U.S. statesman. As U.S. attorney general (1893-95)  under Pres. Grover Cleveland, he set a precedent by using an injunction  to break the Pullman Strike (1894). Appointed U.S. secretary of state in  1895, he was confronted with Venezuela�s request for support in its bor�  der dispute with Britain over the boundary between Venezuela and Brit�  ish Guiana. Olney�s aggressive note to Britain, known as the Olney  Corollary, demanded that Britain submit the dispute to arbitration and  reasserted U.S. sovereignty in the Western Hemisphere in accordance with  the Monroe Doctrine. The matter was in fact settled by arbitration two  years after Olney�s retirement in 1897.</p><p>Olt \'olt\ River River, southern Romania.

There are several resorts and spas along its course through the mountains.</p><p>Olympia Ancient sanctuary and site of the Olympic Games, northwest�  ern Peloponnese, southern Greece. Located 10 mi (16 km) inland from  the Ionian Sea, it was on the northern bank of the Alpheus River. A centre  of Greek religious worship, it held the primarily athletic contests in  honour of Zeus every four years, beginning in 776 bc. In the temple of  Zeus, built c. 460 bc, was the statue of Zeus by Phidias, one of the Seven  Wonders of the World. Excavations have uncovered many ruins, includ�  ing temples and the stadium.</p><p>Olympia City (pop., 2000: 42,514), capital of Washington state, U.S. It  lies at the southern end of Puget Sound, southwest of Tacoma. Originally  called Smithfield, it was renamed for the nearby Olympic Mountains and  incorporated as a city in 1859. It developed port facilities and a lumber-  based economy, supplemented by oyster farming and other industries. Its  harbour is the site of a large merchant reserve fleet. Located at the base of  the Olympic Peninsula, it is the gateway to Olympic National Park.</p><p>Olympic Games Sports festival.

The original Games included footraces, the  discus and javelin throws, the long jump, boxing, wrestling, the pentath�  lon, and chariot races. After the subjugation of Greece by Rome, the  Games declined; they were finally abolished about ad 400. They were  revived in the late 19th century through efforts led in part by Pierre, baron  de Coubertin; the first modern Games were held in Athens. The first Win�  ter Games were held in 1924. The direction of the modem Olympic move�  ment and the regulation of the Games are vested in the International  Olympic Committee, headquartered at Lausanne, Switz. Until the 1970s  the Games adhered to a strict code of amateurism, but since that time pro�  fessional players have also been allowed to participate.

The chief peaks are Mount Olympus, at 7,965 ft  (2,428 m), and Mount Constance, at 7,743 ft (2,360 m). There is heavy  rainfall, creating rainforests dominated by Douglas fir and Sitka spruce.  Some trees are nearly 300 ft (90 m) high and 8 ft (2.5 m) in diameter.</p><p>Olympic National Park National park, northwestern Washington,  U.S. Established in 1938 to preserve the Olympic Mountains and their for�  ests and wildlife, it covers 1,442 sq mi (3,735 sq km); it includes a strip  of Pacific Northwest shoreline geographically separated from the rest of  the park. There are more than 60 glaciers in the park. The western part  includes rainforests; the eastern slopes feature lakes; and the ocean shore  section contains scenic beaches and three Indian reservations.</p><p>Olympus, Mount Mountain peak, northeastern Greece. At 9,570 ft  (2,917 m), it is the highest mountain in Greece. It is part of the Olympus  range, lying on the border between Macedonia and Thessaly, near the Gulf  of Salonika. The summit is snowcapped and often has cloud cover. In  ancient Greece, it was regarded as the abode of the gods and the site of  the throne of Zeus.</p><p>Olympus Mons Large volcano on Mars, the largest known volcano in  the solar system. It consists of a central structure that ascends about 13 mi  (21 km) above Mars� s mean radius and is 335 mi (540 km) wide at the base;  it is surrounded by an outward-facing cliff rising as much 6 mi (10 km)  above the surrounding area. At the summit is a crater 53 mi (85 km) in  diameter. For comparison. Earth�s largest volcano, Mauna Loa, is 75 mi  (120 km) wide at the base and rises 5.6 mi (9 km) above the ocean floor.</p><p>Olynthus \o-'lin-thos\ Ancient Greek city, on the Chalcidice Peninsula,  northeastern Greece. From the late 5th century bc it was the head of a  strong confederacy of Greek towns known as the Chalcidian League. It  was destroyed by Philip II in 348 bc. Excavations have revealed the grid  plan of the ancient town and provided material for studying the relation�  ship between Classical and Hellenistic Greek art.</p><p>om \'om\ In Hinduism and other Indian religions, a sacred syllable con�  sidered the greatest of all mantras. The syllable om is composed of the  three sounds a-u-m (in the Sanskrit language, the vowels a and u join to  become o ), which represent three important triads: earth, atmosphere, and  heaven; the major Hindu gods, Brahma, Vishnu, and Shiva; and the sacred  Vedic scriptures, Rig, Yajur, and Sama (see Vedic religion). Thus om mys�  tically embodies the essence of the universe. It is uttered at the beginning  and end of Hindu prayers, chants, and meditation and is also freely used  in Buddhist and Jain rituals.</p><p>Omagh Vo-ma\ District (pop., 2001: 47,735) and town (pop., 1991:  18,000), Northern Ireland. Formerly in County Tyrone, the district was  established in 1973. The area was ruled by the ancient O�Neill family  (5th-16th centuries), passing to English rule after the flight of Hugh  O�Neill in 1607. It was the site of sectarian violence in 1998, when a car  bomb killed 29 people. Most of the land is grazed by dairy cattle or sheep,  and the rivers contain salmon and trout. Omagh town, the district seat, is  a market and light-manufacturing centre.</p><p>Omaha Vo-ms-.ho, , o-mo- 1 ha\ City (pop., 2000: 390,007), eastern  Nebraska, U.S., on the Missouri River, north of its junction with the Platte  River. The city�s name, meaning �upstream people,� referred to the  Omaha Indians. Omaha was founded in 1854 and incorporated as a city  in 1857. In 1863 it became the starting point for the Union Pacific Rail�  road Co.�s first transcontinental railroad and soon grew into a centre of  trade and industry. The largest city in the state, it is a major livestock and  grain market, as well as a railroad, meat-packing, and insurance centre.  It is home to the University of Nebraska and the Joslyn Art Museum.</p><p>O'Mahony, John (b. 1816, near Mitchelstown, County Cork, Ire.�d.  Feb. 6, 1877, New York, N.Y., U.S.) Irish-American founder of the U.S.  branch of the Fenian Brotherhood (see Fenian movement), an Irish secret  revolutionary society. An Irish resistance leader, he fled to New York in  1853, where he founded and led (1858-66) the Fenians. By 1865 the  American Fenian group had become large and prosperous and was send�  ing money and arms to Ireland. O�Mahony reluctantly backed the Irish  Fenians� decision to stage military raids in Canada against the British,  part of a scheme to hold Canada hostage for the cause of Irish freedom.  The raids failed and he resigned, but he was later called out of retirement  (1872-77).

The Hajar Mountains parallel the shore of  the Gulf of Oman, reaching an elevation of more than 10,000 ft (3,000 m).  A broad expanse of sandy desert covers much of the country. Oman has a  developing mixed economy, and the production and export of petroleum is  its largest sector. It is a hereditary monarchy, with an advisory council; its  head of state and government is the sultan. Human habitation dates to about  the 3rd millennium bc. The Omani tribal system dates to Arab migration  during the 2nd century ad. It was ruled by imams (Muslim religious lead�  ers) of the Ibad! sect from the early Islamic period (mid-8th century) until  the 12th century, when local rule was established. The Portuguese con�  trolled the coastal areas c. 1507-1650, when they were expelled. The Al Bu  SaTd, a dynasty founded in the mid-18th century, still rules Oman.

Educated  in the sciences and philosophy, he was renowned in his country and time  for his scientific achievements, but few of his prose writings survive. His  verses attracted little attention until his roba l Tyat (�quatrains�) were  loosely translated into English by Edward FitzGerald and published in  1859. Many of the quatrains (each of which was intended as an indepen�  dent poem) are of doubtful attribution; most scholars agree on the authen�  ticity of about 50, with controversy over some 200 others.</p><p>ombudsman Vam-.budz-msnV Swedish representative Represen�  tative assigned by a large organization or a government to investigate citi�  zen complaints and suggest solutions. An ombudsman�s office was  established by the Swedish constitution of 1809. The idea soon spread to  other Scandinavian countries and later to New Zealand, Britain, Germany,  Israel, and some states or provinces in the U.S., Australia, and Canada.  An ombudsman�s responsibility is to receive and investigate complaints  and to serve as an independent and impartial arbiter in recommending  what may be done to satisfy the complainant or in explaining why no  action is necessary. Ombudsmen are now used in universities, corpora�  tions, municipalities, and institutions such as hospitals.</p><p>Omdurman V.am-dor-'manN City (pop., 1993 est.: 1,267,000), east-  central Sudan. It is situated on the  left bank of the Nile River just below  the confluence of the Blue and White  Niles. It was an insignificant village  until the victory of al-MAHDi over the  British in 1885. It grew rapidly after  al-Mahdl and his successor, c Abd  Allah, made it their capital. It was  captured by Anglo-Egyptian forces  in 1898 but continued to develop into  the cultural, religious, and commer�  cial centre of The Sudan.

One of the nearer  globular clusters (about 17,000 light-  years away), it is estimated to con�  tain hundreds of thousands of stars, including several hundred variable  stars. John Herschel (see Herschel family) was the first to recognize it as a  star cluster and not a nebula.</p><p>omen Observed phenomenon that is interpreted as signifying good or  bad fortune. The many and varied omens that the ancients noted included  lightning, cloud movements, the flights of birds, and the paths of sacred  animals.

Founded in 1716 as a military stronghold, Omsk became a city in  1804. It remained the headquarters of the Siberian Cossacks until the late  19th century. In 1918-19 it was the seat of the anti-Bolshevik govern�  ment of Adm. Aleksandr Kolchak. Its growth was spurred by the building  of the Trans-Siberian Railroad in the 1890s and the onset of World War II.  Pipelines from the Volga-Urals and western Siberian oil fields supply the  refinery, and the petrochemical industry is also is important.</p><p>On See Heliopolis</p><p>Onassis, Aristotle (Socrates) (b.

The son of a tobacco dealer, he  started a tobacco-importing business in Buenos Aires, Arg. He was made  consul general after negotiating a trade agreement for the Greek govern�  ment. A millionaire by age 25, he bought his first freight ships in 1932.  In the 1940s and �50s his fleet grew until it was larger than the navies of  many countries. He acquired business interests in Monte Carlo, and from  1957 to 1974 he owned and operated Olympic Airways, the Greek  national airline. He conducted a long affair with Maria Callas, and in 1968  married Jacqueline Kennedy (see Jacqueline Kennedy Onassis).</p><p>Onassis, Jacqueline Kennedy orig.

After graduating from George  Washington University in 1951 she took a job as a reporter-photographer  at the Washington Times-Herald. In 1953 she married Sen. John F.  Kennedy, who became president in 1961. As first lady, she restored the  White House to its original Federal style and conducted a televised tour of  the residence. Her graciousness, elegance, and beauty endeared her to the  American public, and her broad culture and ease in speaking Spanish and  French impressed foreign leaders. After her husband�s assassination in  1963 she moved to New York with their children, Caroline (b. 1957) and  John, Jr. (1960-99). In 1968 she married Aristotle Onassis.

He sent  exploring parties throughout the American Southwest to search for gold  and led an expedition into present-day Kansas in 1601. Still searching for  gold, he explored the region west to the Colorado River and south to the  Gulf of California (1604). He resigned in 1607.

It is a sequence of  DNA that has been altered or mutated from its original form, the proto�  oncogene (see mutation). Proto-oncogenes promote the specialization and  division of normal cells. A change in their genetic sequence can result in  uncontrolled cell growth, ultimately causing the formation of a cancerous  tumour. In humans, proto-oncogenes can be transformed into oncogenes  in three ways: point mutation (alteration of a single nucleotide base pair),  translocation (in which a segment of the chromosome breaks off and  attaches to another chromosome), or amplification (increase in the num�  ber of copies of the proto-oncogene). Oncogenes were first discovered in  certain RETROViRUSes and were later identified as cancer-causing agents in  many animals. See also J.

They call themselves Oneyoteaka, meaning  �People of the Standing Stone.� The Oneida were semisedentary and  practiced com agriculture. Longhouses sheltered families related through  maternal descent and belonging to one of three clans. Bear, Turtle, or  Wolf. Each community had a local council that guided the chief or chiefs.  The Oneida supported the colonist cause in the American Revolution and  were attacked by the pro-British Iroquois under Joseph Brant. By the mid-  19th century most Oneida had dispersed. They number some 12,000.</p><p>Oneida Community Utopian religious community founded by John  H. Noyes in Oneida, N.Y., in 1848. Noyes, who believed that the Second  Coming of Jesus Christ had occurred in ad 70, and his disciples formed  their first religious society in Putney, Vt., in 1841 in order to establish the  millennial kingdom. Their practice of �complex marriage,� according to  which each adult community member was married to each adult of the  opposite sex, aroused the hostility of the townspeople, and they were  obliged to move to Oneida. The Oneida group lived communally and  flourished for 30 years, supporting itself by farming and manufacturing  steel traps, silverware, and other items. The community broke up in 1879,  and two years later the remaining members reorganized it as a commer�  cial enterprise, which is noted for the manufacture of silver plate.</p><p>O'Neill, Eugene (Gladstone) (b. Oct. 16, 1888, New York, N.Y.,  U.S.�d. Nov. 27, 1953, Boston, Mass.) U.S. playwright. The son of a  touring actor, he spent an itinerant youth as a seaman, heavy drinker, and  derelict, then began writing plays while recovering from tuberculosis  (1912). His one-act Bound East for Cardiff (1916) was produced by the  experimental Provincetown Payers, which also staged his other early plays  (1916-20). Beyond the Horizon was produced on Broadway in 1920,  earning him his first Pulitzer Prize. Enormously prolific, he often wrote  about tortured family relationships and the conflict between idealism and  materialism. Soon recognized as a major dramatist, he became widely  translated and produced. His many plays of the 1920s include The  Emperor Jones (1921), The Hairy Ape (1922), Anna Christie (1922;  Pulitzer Prize), Desire Under the Elms (1925), The Great God Brown  (1926), and Strange Interlude (1928; Pulitzer Prize). Among his later  plays are Mourning Becomes Electra (1931), Ah! Wilderness (1933; his  only comedy). The Iceman Cometh (1946), and the autobiographical Long  Day�s Journey into Night (produced 1956; Pulitzer Prize), considered his  masterpiece.

It covers 412,581 sq mi (1,068,580  sq km). Its capital is Toronto. Before European settlement, the area was  inhabited by Iroquois and Algonquin Indian tribes. In the 17th century it  was visited by French explorers and missionaries. It passed to the British  in 1763 after the French and Indian War. It was the scene of many battles  in the War of 1812. The area was known as Canada West from 1841  until 1867, when it became one of four provinces of the new Dominion  of Canada. Northern Ontario has a rocky and rugged terrain with thick  forests, bogs, lakes, and extensive mineral reserves. Southern Ontario is  an important farming and industrial region and is the centre of Canada�s  population and urban development.

The Niagara River is the lake�s main feeder. There are five islands  at its eastern end, where the lake discharges into the St. Lawrence River  near Kingston, Ont. The Welland Canal and the Niagara River connect it  to Lake Erie to the southwest. It was visited by Samuel de Champlain in  1615; its early French name was Lac Frontenac. Ports on the lake include  Toronto and Hamilton, Ont., and Rochester and Oswego, N.Y.</p><p>ontological argument Argument that proceeds from the idea of God  to the reality of God. It was first clearly formulated by St. Anselm in his  Proslogion (1077-78); a later famous version is given by Rene Descartes.  Anselm began with the concept of God as that than which nothing greater  can be conceived. To think of such a being as existing only in thought and  not also in reality involves a contradiction, since a being that lacks real  existence is not a being than which none greater can be conceived. A yet  greater being would be one with the further attribute of existence. Thus  the unsurpassably perfect being must exist; otherwise it would not be  unsurpassably perfect. This is among the most discussed and contested  arguments in the history of thought.</p><p>ontology Theory of being as such. It was originally called �first phi�  losophy� by Aristotle.

This view was later strongly  criticized by David Hume and Immanuel Kant. Ontology was revived in the  early 20th century by practitioners of phenomenology and existentialism,  notably Edmund Husserl and his student Martin Heidegger. In the English-  speaking world, interest in ontology was renewed in the mid-20th century  by W.V.O. Quine; by the end of the century it had become a central dis�  cipline of analytic philosophy.

They are sometimes called velvet worms for their  velvety skin. The common genus Peripatus occurs in the West Indies,  Central America, and northern South America. Onychophorans are slen�  der and segmented; each segment has a pair of short legs. Species range  from 0.6 to 6 in. (14-150 mm) long. They live in humid, hidden spots:  in forest litter, wood crevices, termite nests, or the soil, sometimes to a  depth of more than 3 ft (1 m). They use their jaws to open captured prey  (often small insects) and suck out the juices.</p><p>onyx \'a-niks\ Striped, semiprecious variety of the silica mineral agate  with white and black alternating bands. Other varieties include carnelian  onyx, with white and red bands, and sardonyx, with white and brown  bands. Its properties are the same as those of quartz. Onyx is used in  carved cameos and intaglios because its layers can be cut to show a colour  contrast between the design and the background. It is found worldwide,  but chiefly in India and South America.</p><p>Oort cloud Vast spherical cloud of small, icy bodies orbiting the Sun  at distances ranging from about 0.3 light-year to one light-year or more  that is probably the source of most long-period comets. In 1950 the Dutch  astronomer Jan Hendrik Oort (1900-92) noted that no comets have orbits  that would indicate an interstellar origin. He proposed that the Sun is sur�  rounded by billions of these objects, which are only occasionally detect�  able when they enter the inner solar system. The Oort cloud is believed  to be composed of primordial bodies dating from the formation of the  solar system (see solar nebula). Whether the Oort cloud merges, in its inner  region, into the disk-shaped Kuiper belt is not known.</p><p>Op art or Optical art Branch of mid-20th-century geometric abstract  art that deals with optical illusion. Op art painters devised complex opti�  cal spaces by manipulating repetitive forms such as parallel lines, check�  erboard patterns, and concentric circles or by creating chromatic tension  from the juxtaposition of complementary colours, thereby creating the  illusion of movement. Principal artists of the Op movement in the late  1950s and the �60s include Victor Vasarely, Bridget Riley (b. 1931), and  Larry Poons (b. 1937).</p><p>opal A hydrated, noncrystalline silica mineral used extensively as a gem�  stone. Its chemical composition is  similar to that of quartz but generally  with a variable water content. Pure  opal is colourless, but impurities  generally give it various dull colours  ranging from yellow and red to  black. Black opal is especially rare  and valuable. White opal and fire  opal, characterized by yellow,  orange, or red colour, are much more  common. Various forms of common  opal are widely used as abrasives,  insulation material, and ceramic  ingredients. Opal is most abundant in  volcanic rocks, especially in areas of  hot-spring activity. The finest gem  opals have been found in Australia;  other areas that yield gem material  include Japan, Mexico, Honduras,</p><p>India, New Zealand, and the U.S.</p><p>OPEC in full Organization of  the Petroleum Exporting  Countries Multinational organiza�  tion established in 1960 to coordinate the petroleum production and export  policies of its members. Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela  were the original members; they were joined by Qatar (1961), Indonesia  and Libya (1962), Abu Dhabi (1967; membership transferred to the United</p><p>Arab Emirates, 1974), Algeria (1967), and Nigeria (1971). Ecuador (1973)  and Gabon (1975) are no longer OPEC members. Policy decisions are  taken by consensus at its Vienna headquarters. In 1973 OPEC began a  series of oil price increases in retaliation for Western support of Israel in  the 1973 Arab-Israeli war, and OPEC members� income greatly increased  as a result. Internal dissent, the development of alternative energy sources  in the West, and Western exploitation of oil sources in non-OPEC coun�  tries subsequently combined to reduce the organization�s influence. OPEC  countries supply about two-fifths of the world�s oil consumption and pos�  sess about two-thirds of the world�s proven oil reserves.</p><p>open cluster or galactic cluster Any group of Population I (see  Populations I and II) stars with a common origin, held together by mutual  gravitation (not to be confused with a cluster of galaxies). Stars in open  clusters are much more scattered than those in globular clusters. All known  open clusters contain from about 10 to 1,000 or more stars (about half  contain fewer than 100) and have diameters of 5-75 light-years. More  than 1,000 have been discovered in the Milky Way Galaxy; well-known  examples include the Pleiades and the Hyades.</p><p>Open Door policy Statement of U.S. foreign policy toward China.  Issued by U.S. secretary of state John Hay (1899), the statement reaffirmed  the principle that all countries should have equal access to any Chinese  port open to trade. The U.S. sent notes to Britain, Germany, France, Italy,  Japan, and Russia explaining the policy to prevent them from establish�  ing separate spheres of influence in China. Their replies were evasive, but  the U.S. considered them acceptances of the policy. Japan�s violation of  the policy in 1937 led the U.S. to impose an oil embargo. The policy was  discontinued with the communist takeover of China in 1949.</p><p>open-heart surgery Any surgical procedure opening the heart and  exposing one or more of its chambers, most often to repair valve disease  or correct congenital heart malformations (see congenital heart disease).  Invention of the heart-lung machine (see artificial heart), which allows the  heart to be stopped during surgery, made it possible. The first successful  open-heart surgery was performed in the U.S. in 1953 by John H. Gib�  bon, Jr., to close an atrial septal defect.</p><p>open-hearth process or Siemens-Martin process Steelmaking  technique that for most of the 20th century accounted for most steel made  in the world. William Siemens made steel from pig iron in a reverberatory  furnace of his design in 1867. The same year the French manufacturer  Pierre-Emile Martin (1824-1915) used the idea to produce steel by melt�  ing wrought iron with steel scrap. Siemens used the waste heat given off  by the furnace: he directed the fumes from the furnace through a brick  checkerwork, heating it to a high temperature, and then used the same  path to introduce air into the furnace; the preheated air significantly  increased the flame temperature. The open-hearth process furnace (which  replaced the Bessemer process) has itself been replaced in most industrial�  ized countries by the basic oxygen process and the electric furnace. See also</p><p>REVERBERATORY FURNACE.</p><p>open market operation Any of the purchases and sales of govern�  ment securities and commercial paper by a central bank in an effort to  regulate the money supply and credit conditions. Open market operations  can also be used to stabilize the prices of government securities. When  the central bank buys securities on the open market, it increases the  reserves of commercial banks, making it possible for them to expand their  loans and investments. It also increases the price of government securi�  ties, equivalent to reducing their interest rates, and decreases interest rates  generally, thus encouraging investment. If the central bank sells securi�  ties, the effects are reversed. Open market operations are usually per�  formed with short-term government securities such as treasury bills.</p><p>opera Musical drama made up of vocal pieces with orchestral accom�  paniment, overtures, and interludes. Opera was invented at the end of the  16th century in an attempt by the Camerata (an academy of Florentine  poets, musicians, and scholars) to imitate ancient Greek drama, which was  known to have been largely sung or chanted. Since no actual Greek music  was known, composers had considerable freedom in reconceiving it. Imi�  tations of Greek pastoral poetry became the basis for early opera libretti.  The first operas, Dafne by Jacopo Peri (1561-1633) in 1598 and by Giuuo  Caccini about the same time, are now lost; the earliest surviving opera is  Peri�s Euridice (1600). They consisted of lightly accompanied vocal  melody closely imitating inflected speech. Claudio Monteverdi, the great�  est early operatic figure, composed the first masterpiece, Orfeo, in 1607;  unlike its predecessors, it is scored for a small orchestra. With this work,</p><p>Black opal from Australia; in the collec�  tion of the Department of Earth Sci�  ences, Washington University, St. Louis,  Mo.</p><p>JOHN H.

In France, Jean-Baptiste  Lully produced a prototype for courtly opera that influenced French opera  through the mid-18th century. Jean-Philippe Rameau, George Frideric Han�  del, and Christoph Willibald Gluck were the most significant opera com�  posers of the first two-thirds of the 18th century; their works were  surpassed by the brilliant operas of Wolfgang Amadeus Mozart. In the  early 19th century, Gioacchino Rossini and Gaetano Donizetti dominated  Italian opera. In the later 19th century the greatest works were those of  Giuseppe Verdi and Richard Wagner; the latter, with his bold innovations,  became the most influential operatic figure since Monteverdi. Richard  Strauss and Giacomo Puccini wrote the most popular late 19th- and early  20th-century operas. Though the death of Puccini in 1924 is often cited  as the end of grand opera, new and often experimental works�by com�  posers such as Alban Berg, Benjamin Britten, Gian Carlo Menotti, John  Adams, and Philip Glass �continued to be produced to critical acclaim.  Opera entered the 21st century as a vibrant and global art form.

Its roles include managing  the functioning of the computer hardware, running the applications pro�  grams, serving as an interface between the computer and the user, and  allocating computer resources to various functions. When several jobs  reside in the computer simultaneously and share resources (multitasking),  the OS allocates fixed amounts of CPU time and memory in turn or allows  one job to read data while another writes to a printer and still another  performs computations. Through a process called time-sharing, a large  computer can handle interaction with hundreds of users simultaneously,  giving each the perception of being the sole user. Modern computer oper�  ating systems are becoming increasingly machine-independent, capable  of running on any hardware platform; a widely used platform-independent  operating system in use today on mainframe computers is UNIX. Most per�  sonal computers run on Microsoft�s Windows operating system, which  grew out of and eventually replaced MS-DOS. See also Linux.</p><p>operationalism In the philosophy of science, the attempt to define all  scientific concepts in terms of specifically described operations of mea�  surement and observation. The length of a rod, for example, may be  defined as the number of times a certain stick can be laid end to end  alongside it. Propositions that are not amenable to verification through  measurement and observation are rejected as meaningless (see also logi�  cal positivism). Operationalists rejected the idea of nature as a thing-in-itself  existing behind the appearances observed in experimentation. Operation�  alism is closely associated with the work of the U.S. physicist Percy W.  Bridgman (1882-1961).</p><p>operations management See production management</p><p>operations research Application of scientific methods to manage�  ment and administration of military, government, commercial, and indus�  trial systems. It began during World War II in Britain when teams of  scientists worked with the Royal Air Force to improve radar detection of  enemy aircraft, leading to coordinated efforts to improve the entire sys�  tem of early warning, defense, and supply. It is characterized by a sys�  tems orientation, or systems engineering, in which interdisciplinary  research teams adapt scientific methods to large-scale problems that must  be modeled, since laboratory testing is impossible. Examples include  resource allocation and replacement, inventory control, and scheduling of  large-scale construction projects.</p><p>operator, differential See differential operator</p><p>operetta Musical drama similar to opera, usually with a romantically  sentimental plot, employing songs, dances, and orchestral interludes inter�  spersed with spoken dialogue. The modern tradition begins with Jacques  Offenbach, who wrote some 90 operettas and inspired a Viennese tradi�  tion that began with the works of Franz von Suppe and Johann Strauss.  In Britain most of the 14 comic operettas (1871-96) of W.S. Gilbert and  Arthur Sullivan have been enduringly popular. In the U.S. the works of  such European immigrant composers as Victor Herbert and Rudolf Friml  were widely popular in the early 20th century.

By provid�  ing a means to produce proteins only when and where they are required,  the operon allows the cell to conserve energy. A typical operon consists  of a group of structural genes that code for enzymes involved in a meta�  bolic pathway, such as the biosynthesis of an amino acid. A single unit  of messenger RNA is transcribed from the operon and is then translated  into separate proteins. Operons are controlled by various regulatory ele�  ments that respond to environmental cues. The operon system was first  proposed by Francois Jacob and Jacques Monod in the early 1960s.</p><p>Opet Vo- ,pet\ Ancient Egyptian festival of the New Year. In the celebra�  tion of Opet, statues of Amon and Mut and their son Khons were carried  down the Nile on barges in a ritual journey from their shrines at Karnak  to the temple of Luxor. There the statues remained about 24 days, a fes�  tival time for Luxor. The images were returned to Karnak by the same  route in a second public appearance that closed the festival.</p><p>Ophite Va-.fit, 'o-.fnA Member of any of several Gnostic sects that flour�  ished in the Roman empire in the 2nd century ad and for several centu�  ries thereafter. The sects shared a dualistic theology, opposing a beneficent  and entirely spiritual Supreme Being to a chaotic and evil material world.  To the Ophites, the human dilemma resulted from the mixture of these  conflicting spiritual and material elements in human nature. Only gnosis,  the esoteric knowledge of good and evil, could redeem one from the bonds  of matter. See also dualism, Gnosticism.</p><p>ophthalmology \ l af-th9l-'ma-b-je\ Medical specialty dealing with the  eyes, dating to 1805. Frans C. Donders�s 1864 advances in optics allowed  eyeglasses to be fitted to vision problems. The ophthalmoscope made it  possible to look inside the eye and relate eye defects to internal condi�  tions. More recent advances include eye exams, early treatment of con�  genital defects, and eye banks to store corneas for transplants.  Ophthalmologists test visual function and examine the eye for faulty  development, disease, injury, degeneration, aging, or refractive errors.  They prescribe treatment for eye disease and lenses for refraction and  perform surgery when needed. See also optometry, visual-field defect.</p><p>Ophuls Vo-ftelsX, Max orig. Max Oppenheimer (b. May 6, 1902,  Saarbriicken, Ger.�d. March 26, 1957, Hamburg, W.Ger.) German film  director. An actor, stage director, and producer in Germany and Austria  (1921-30), he gained renown as a film director with Liebelei (1933). He  left Nazi Germany and directed popular but undistinguished films in  France, Russia, Italy, and The Netherlands until 1940, when he moved to  the U.S. In Hollywood he directed The Exile (1947), Letter from an  Unknown Woman (1948), and The Reckless Moment (1949). He returned  to France to make The Roundabout (1950), House of Pleasure (1952),  and The Sins of Lola Montes (1955), considered his masterpiece. His son,  Marcel (b. 1927), worked in France principally as a maker of documen�  tary films, most notably The Sorrow and the Pity (1971), which examines  French conduct under German occupation.</p><p>Opie, Eugene Lindsay (b.

Early in his career, he correctly deduced  that degenerative changes in the islets of Langerhans caused diabetes mel-  litus and theorized that blockage of the junction of the bile and pancre�  atic ducts caused acute pancreatitis. He later showed that tuberculosis (TB)  was spread by contact, including from one family member to another. His  work led to use of X-ray films to detect asymptomatic TB, the sputum test  to predict the chance of its spread, and injection of heat-killed tubercle  bacilli to prevent infection.</p><p>opium Organic compound, a narcotic drug known since ancient Greek  times, obtained from exuded juice of immature fruit capsules of the opium  poppy. Opium has legitimate medical uses, as the source of the alkaloids  codeine and morphine and their derivatives. It is also used illicitly, either  raw or purified as alkaloids and their derivatives (including heroin).  Opium alkaloids of one type (e.g., morphine, codeine) act on the nervous  system, mimicking the effects of endorphins; they are analgesic, narcotic,  and potentially addicting (see drug addiction). Those of a second type,  including papaverine and noscapine, relieve smooth muscle spasms and  are not analgesic, narcotic, or addicting. Habitual opium use produces  physical and mental deterioration and shortens life. Overdose can cause  death by depressing respiration.</p><p>opium poppy Flowering plant ( Papaver somniferum) of the family  Papaveraceae, native to Turkey.

It is also grown for its tiny  nonnarcotic ripe seeds, which are kidney-shaped and grayish blue to dark  blue; the seeds are used in bakery products and for seasoning, oil, and  birdseed.</p><p>Opium Wars Two trading wars of the mid-19th century in China. The  first (1839-42 was between China and Britain, and the second (1856-60;  also called the Arrow War or Anglo-French War) was between China and  a British-French alliance. Trade developed between China and Western  countries from the late 16th century. The Chinese, accustomed to tribu�  tary relationships with others, required that Westerners pay for Chinese  goods with silver currency. To offset a growing negative flow of silver at  home, the British created a market for opium in China and began import�  ing it there illegally. As demand for opium grew, China tried to stop the  practice, and hostilities broke out. Britain quickly triumphed, and the  resultant Treaty of Nanjing (Nanking; 1842; the first of a series of unequal  treaties between China and Western countries and, eventually, Japan) was  a blow to China. The outbreak of the second war resulted in the Treaty  of Tianjin (Tientsin; 1858), which required further Chinese concessions.  When China refused to sign subsequent treaties, Beijing (Peking) was  captured and the emperor�s summer palace burned. The overall result of  these conflicts was to weaken the Chinese imperial system, greatly expand  Western influence in China, and pave the way for such uprisings as the  Taiping and Boxer rebellions.

He graduated from Harvard  University, did research at Cambridge University, and earned a doctorate  from Gottingen University. He returned to the U.S. to teach at the Cali�  fornia Institute of Technology (1929^47). His research focused on energy  processes of subatomic particles, and he trained a generation of Ameri�  can physicists. In World War II he was named director of the army�s  atomic-bomb project, later known as the Manhattan Project, and set up  the laboratory in Los Alamos, N.M., that remains a principal weapons-  research laboratory. He directed the Institute for Advanced Study in Prince�  ton (1947-66). He strongly opposed the development of the hydrogen  bomb, and in 1953 he was suspended from secret nuclear research as an  alleged communist sympathizer and a security risk; the case, which pit�  ted him against Edward Teller, became a worldwide cause celebre. In 1963  he was reinstated and awarded the Enrico Fermi Award.</p><p>opportunity cost In economic terms, the opportunities forgone in the  choice of one expenditure over others. For a consumer with a fixed  income, the opportunity cost of buying a new dishwasher might be the  value of a vacation trip never taken or several suits of clothes unbought.</p><p>The concept of opportunity cost allows economists to examine the rela�  tive monetary values of various goods and services.</p><p>opposition, square of Geometrical representation of the traditional  logical relations of opposition (contradictories, contraries, subalterns)  among the four types of propositions (universal affirmative or  A-proposition, universal negative or E, particular affirmative or I, particu�  lar negative or O) in the Aristotelian doctrine of the syllogism. At the top  left is the A; at the top right is the E; below the A is the I; and below the  E is the O. The A and the O, like the E and I, are contradictories (diago�  nal relations); the A and the E are contraries; and the I is subaltern to  (hence implied by) the A, the O subaltern to the E. Whereas contradic�  tories have opposite truth-values (one true, the other false), contraries  cannot both be true but can both be false.</p><p>optical activity Ability of a substance to rotate the plane of polarization  of a beam of light passed through it, either as crystals or in solution. Clock�  wise rotation as one faces the light source is �positive,� or dextrorotary;  counterclockwise rotation �negative,� or levorotary. Louis Pasteur was the  first to recognize that molecules with optical activity are stereoisomers (see  isomerism). Optical isomers occur in pairs that are nonsuperimposable mirror  images of one another. They have the same physical properties except for  their effect on polarized light; in chemical properties they differ only in  their interactions with other stereoisomers (see asymmetric synthesis).</p><p>optical character recognition See OCR  optical scanner See optical scanner</p><p>optics Science concerned with the production and propagation of light,  the changes it undergoes and produces, and closely related phenomena.  Physical optics deals with the nature and properties of light; geometric  optics deals with the formation of images by mirrors, lenses, and other  devices that use light. Optical data processing involves manipulation of  the information content of an image formed by coherent (one-wavelength)  optical systems. The study of optics has led to the development of devices  such as EYEGLASSES and CONTACT LENSeS, TELESCOPES, MICROSCOPES, CAMERAS, BIN�  OCULARS, lasers, and optical fibres (see fibre optics).</p><p>Optimates and Populares \,ap-ti- , ma-tez... 1 pap-y9- , lar-ez\ Ideo�  logical positions in ancient Rome that became defined in the early 1st  century bc. Both groups came from the wealthier classes. The Optimates  (Latin: �Best Ones,� �Aristocrats�) promoted the dominance of the Sen�  ate and the proper balance of the constitution. The Populares (�Dema�  gogues,� �Populists�) used and defended the powers of the popular  assemblies and the office of tribune and advocated such measures as land  distribution, debt cancellation, and subsidized grain allowances. Their  polarization led to civil wars�notably those between Julius Caesar and  Pompey and between Octavian (Augustus) and Mark Antony �and the fall  of the republic with Augustus�s accession.</p><p>optimization Field of applied mathematics whose principles and meth�  ods are used to solve quantitative problems in disciplines including phys�  ics, biology, engineering, and economics. Questions of maximizing or  minimizing functions arising in the various disciplines can be solved using  the same mathematical tools (see maximum; minimum). In a typical optimi�  zation problem, the goal is to find the values of controllable factors deter�  mining the behaviour of a system (e.g., a physical production process, an  investment scheme) that maximize productivity or minimize waste. The  simplest problems involve functions (systems) of a single variable (input  factor) and may be solved with differential calculus. Linear programming was  developed to solve optimization problems involving two or more input  variables. See also simplex method.</p><p>optometry \ap-'ta-ni3-tre\ Profession concerned with examining the  eyes for defects or faults of refraction. Optometrists prescribe optical aids  (e.g., eyeglasses, contact lenses), supervise eye exercise programs to treat  vision problems, and examine the eyes for disorders such as glaucoma  and cataracts. They are generally not licensed to prescribe drugs or trained  to perform surgery.

Its members seek personal Christian perfection, strive to imple�  ment Christian ideals in their chosen occupations, and promote Christian  values to society as a whole. Opus Dei, in full Prelature of the Holy Cross  and Opus Dei, was founded in 1928 in Spain by Josemarfa Escriva de  Balaguer y Alba (canonzied in 2002). It is theologically conservative and  accepts the teaching authority of the church without question. It was  granted special status as the first and only personal prelature in the church  by Pope John Paul II in 1982 and has established numerous vocational  schools and universities. It is also highly controversial, accused of secrecy,  using cult-like recruiting practices, and having grand political ambitions.  There are separate organizations for men and women, which, since 1982,  have been headed by a prelate elected by its members. At the beginning  of the 21st century priests constituted only a tiny percentage of the orga�  nization, numbering roughly 1,600 of the nearly 84,000 members living  in 80 countries.</p><p>oracle Source of a divine communication delivered in response to a  petitioner�s request. Ancient Greece and Rome had many oracles. The  most famous was that of Apollo at Delphi, where the medium was a woman  over 50 called the Pythia. After bathing in the Castalian spring, she appar�  ently would descend into a basement cell, mount a sacred tripod, and chew  the leaves of the laurel, sacred to Apollo. Her utterances, which were often  highly ambiguous, were interpreted by priests. Other oracles, including  those at Claros (Apollo), Amphicleia (Dionysus), Olympia (Zeus), and Epi-  daurus (Asclepius), were consulted through various other methods; for  example, the oldest of the oracles, that of Zeus at Dodona, spoke through  the whispering of the leaves of a sacred oak. At some shrines, the inquirer  would sleep in the holy precinct and receive an answer in a dream.</p><p>oral tradition Cultural information passed on from one generation to  the next by storytellers. The forms of oral tradition include poetry (often  chanted or sung), folktales, and proverbs as well as magical spells, reli�  gious instruction, and recollections of the past. Music and rhyme com�  monly serve as both entertainment and aids to memory. Epic poems  concerning the destiny of a society or summarizing its myths often begin  as oral tradition and are later written down. In oral cultures, oral tradi�  tion is the only means of communicating knowledge. The prevalence of  radio, television, and newspapers in Western culture has led to the decline  of oral tradition, though it survives among old people and some minority  groups as well as among children, whose games, counting rhymes, and  songs are transmitted orally from generation to generation.</p><p>Oran \o-'ran\City (pop., 1998: 692,516), northwestern Algeria. Situated  on the Mediterranean Sea, it is about midway between Tangier, Morocco,  and Algiers. With the adjacent Mers el-Kebir, it is the country�s second  largest port. Founded in the 10th century by Andalusians as a base for  trade with the northern African hinterland, it was held by the Spanish until  1708, when it fell to the Ottomans. It was devastated by an earthquake in  1790. In 1792 the Ottomans settled a Jewish community there. In 1831 it  was occupied by the French, who established a modem port and naval  base. In World War II (1939�45) it came under the control of the Allied  Powers. Most of its European inhabitants left after Algerian independence  in 1962. It is divided into a waterfront and the old and new city sections  built on terraces above it.</p><p>orange Any of several species of small trees or shrubs in the genus  Citrus of the rue (or citrus) family and their fruits. Grown in tropical and  subtropical regions, the nearly round fruits have leathery, oily rinds and  edible, juicy inner flesh rich in vitamin C. Key commercial species include  the China (sweet, or common) orange; the mandarin orange (including  tangerines); and seedless navel oranges. The tree has broad, glossy,  medium-size evergreen leaves, leafstalks with narrow wings, and very  fragrant flowers. It bears fruit abundantly for 50-80 years. Oranges do  not improve in quality off the tree, so they are picked when fully ripe. A  sizeable portion of the U.S. crop is processed for frozen concentrated  juice. By-products include essential oils, pectin, candied peel, orange mar�  malade, and stock feed.</p><p>Orange, house of Princely dynasty and royal family of The Nether�  lands.

In 1815 William VI became William I, king of The Neth�  erlands. Through his descendants, the male line of the royal dynasty</p><p>continued until 1890, when Wilhelmina, daughter of William III, became  queen. In 1908 she decreed that her descendants should be styled princes  and princesses of Orange-Nassau.</p><p>Orange Free State Former province, central South Africa. Before the  arrival of the Europeans, the area was the home of Bantu- speaking  peoples. Afrikaners came in large part during the Great Trek of the 1830s.  Britain administered the territory from 1848 to 1854; then the indepen�  dent Orange Free State was established. British rule was reimposed fol�  lowing the South African War in 1902, though self-government was later  restored. In 1910 it became the Orange Free State province of the Union  of South Africa (from 1961 the Republic of South Africa). After the South  African elections of 1994, it became the province of Free State. Blacks  make up about 80% of the population; most of the whites speak Afrikaans.  The province�s capital is Bloemfontein.</p><p>Orange River River, southern Africa. It rises in the Lesotho Highlands  as the Sinqu River and flows west as the Orange across South Africa. It  passes the southern edge of the Kalahari Desert and winds through the  Namib Desert before draining into the Atlantic Ocean in South Africa. It  forms the border between South Africa and Namibia. It is about 1,300 mi  (2,100 km) long. There are some irrigated sections along the river and  many dams but no large towns.</p><p>orangutan \d-'raq-9- l tar)\ or orang Species (Pongo pygmaeus , fam�  ily Hominidae) of arboreal great ape,  found only in the lowland swamp  forests of Borneo and Sumatra but  originally in the tropical forests of  South Asia as well. The orangutan  (Malaysian for �person of the for�  est�) has a short thick body, long  arms, short legs, and shaggy reddish  hair. Males are about 4.5 ft (137 cm)  tall and weigh about 185 lb (85 kg);  females are smaller. Orangutans are  placid, deliberate, ingenious, and  persistent. Males have flat, fatty  cheekpads and a baglike, pendulous  swelling at the throat. Orangutans  use all four limbs to walk and climb.</p><p>They eat mostly figs and other fruits  and some leaves, bark, and insects.</p><p>They sleep in trees on a platform  built of interwoven branches. Adults  are solitary and live far apart, com�  ing together only for a brief court�  ship. The mother carries and nurses the single young for almost three  years. Though generally silent, the adult male has a loud, roaring �long  call.� The orangutan is an endangered species.</p><p>Oranjestad Vo-'ran-yo-.statV Seaport and chief administrative town  (pop., 2000: 26,355), Aruba, Netherlands Antilles.

The term derives from the oratories, com�  munity prayer halls set up by St. Philip Neri in the mid 16th century in a  Counter-Reformation attempt to provide locales for religious edification  outside the church itself, and the oratorio remained a nonliturgical (and  non-Latin) form for moral musical entertainment. The first oratorio, really  a religious opera, was written in 1600 by Emilio del Cavaliere, and the ora�  torio�s development closely followed that of opera. Giacomo Carissimi pro�  duced an important body of Italian oratorios, and Marc-Antoine Charpentier  transferred the oratorio to France in the later 17th century. In Germany the  works of Heinrich Schutz anticipate the oratorio-like Passions of Johann  Sebastian Bach. The most celebrated oratorio composer was George Frideric  Handel; his great English works include the incomparable Messiah (1742).  Handel inspired Franz Joseph Haydn�s great Creation (1798) and exerted  great influence on the 19th-century oratorio, whose composers include  Hector Berlioz, Felix Mendelssohn, and Franz Liszt. Though the oratorio  thereafter declined, 20th-century oratorio composers included Edward  Elgar, Igor Stravinsky, Arthur Honegger, and Krzysztof Penderecki.</p><p>Orbison, Roy (b.

His career waned after the death of his wife in a motorcycle accident  (1966) and the death of two sons in a fire (1968). He made a comeback  in the 1980s; with Bob Dylan, George Harrison (1943-2001), and Tom  Petty (b. 1953) he formed the band the Traveling Wilburys.</p><p>orbital Mathematical expression, called a wave function, that describes  properties characteristic of no more than two electrons near an atomic  nucleus or molecule. An orbital can be considered a three-dimensional  region in which there is a 95% probability of finding an electron. Atomic  orbitals are designated by a combination of numerals and letters (e.g.. Is,  2 p, 3d, 4 f). The numerals are the principal quantum number and are related  to the atomic energy level and distance from the nucleus; the letters indi�  cate the orbital�s angular momentum and hence its shape. An s orbital  with zero net orbital angular momentum is spherical. A p orbital with one  fundamental unit of angular momentum, fi, is shaped somewhat like a  dumbbell ( fi is Planck�s constant, h, divided by 2k). The shapes of the  other orbitals are more complicated. Molecular orbitals have geometries  determined by the overlap of two or more atomic orbitals and are desig�  nated by Greek symbols, e.g., a and n.</p><p>orca See killer whale</p><p>Orcagna \or-'kan-ya\, Andrea orig.

Today the term orchestra usually refers to the traditional large Western  ensemble of bowed stringed instruments with brass, woodwind, and percus�  sion instruments, with several players to each string part. The develop�  ment of the orchestra coincides with the early history of opera. A major  antecedent of the modern orchestra was that of the mid-17th-century  French court, especially as employed by Jean-Baptiste Lully; it was domi�  nated by 24 bowed strings but also often included woodwind instruments.  Trumpets, horns, and timpani were often added in the early 18th century  p_ and were standard by the time of Franz Joseph Haydn. During the 19th</p><p>century there was a considerable expansion, particularly in the number  wm and variety of wind and percussion instruments; some works called for</p><p>ifl well over 100 musicians. The symphony orchestra changed little in the</p><p>20th century.

Once entirely dependent on what was available  or customary, composers began to explore the musical potential of instru�  mental combinations with the advent of the modern orchestra in the mid-  to late 18th century. The first great orchestration text was written by Hec�  tor Berlioz in 1844.</p><p>orchid Any of the 15,000-35,000 species in 400-800 genera of non-  woody perennial plants that make up  the family Orchidaceae.

The testicles�  rich blood and lymphatic supply block most infections in the absence of  severe injury. Usual symptoms are high fever, sudden pain in the testicle,  nausea and vomiting, and swelling, tightness, and tenderness of the gland.  Fluids with pus or blood may accumulate in the scrotum, which is gen�  erally red and thickened. Treatment may include antibiotics, bed rest,  support of the testes, compresses, and surgery or drainage.</p><p>Orchomenus \6r-'ka-m9-n9s\ Ancient city, northwestern Boeotia,  Greece. It was the northernmost fortified town in Mycenaean times and  controlled a large part of Boeotia. In c. 550 bc it became one of the first  cities to coin money, thereby gaining fame for its wealth. It was frequently  attacked and finally destroyed by Thebes in the 4th century bc.

After the Russian Revolution of  1917, he became chairman of the Caucasian bureau (1921) and helped the  Red Army conquer Georgia, forcing its merger with Armenia and Azer�  baijan into the Transcaucasian Federal Republic and then into the Soviet  Union. He became a member of the Politburo (1930) and commissar for  heavy industry (1932), but in the mid-1930s he opposed Joseph Stalin�s  industrial policy. His sudden death was ascribed to natural causes, but  Nikita Khrushchev later charged (1956) that Stalin had driven him to suicide.</p><p>ore Aggregate of economically important minerals that is sufficiently rich  to separate for a profit. Although more than 3,500 mineral species are</p><p>known, only about 100 are considered ore minerals. The term originally  applied only to metallic minerals (see native element) but now includes  such nonmetallic substances as sulfur, calcium fluoride (fluorite), and  barium sulfate (barite). Ore is always mixed with unwanted rocks and  minerals, known collectively as gangue. The ore and the gangue are mined  together and then separated. The desired element is then extracted from  the ore. The metal may be still further refined (purified) or alloyed with  other metals.</p><p>oregano Flavourful dried leaves and flowering tops of any of various  perennial herbs of the MINT family, particularly Origanum vulgare.

Lying  on the Pacific Ocean, it is bordered by Washington, Idaho, Nevada, and  California. It covers 97,073 sq mi (251,419 sq km). Its capital is Salem.  The Columbia River forms its northern boundary; the Snake River is its upper  eastern boundary. The Cascades Range, with Mount Hood, is in western  central Oregon. First sighted by Spanish explorers, it was visited by Fran�  cis Drake in 1579 and by James Cook in 1778. The area was inhabited by  many American Indian peoples when in 1792 Capt. Robert Gray explored  the Columbia River, giving the U.S. a claim to the region. The river�s mouth  was reached by the Lewis and Clark Expedition in 1805. The first white  settlement was founded at Astoria in 1811 by the fur trader John J. Astor.  Settlement of the area accelerated from c. 1843 with mass migration over  the Oregon Trail. It was part of the Oregon Territory and was admitted to  the Union as the 33rd state in 1859. The state�s economy is dependent on  its forests, farms, and livestock. Salmon and shellfish are the bases of the  fishing industry. Centres of population, arts, and education are Portland,  Eugene, and Medford.</p><p>Oregon Caves National Monument National monument, south�  western Oregon, U.S. It is a single cave comprising a series of chambers  joined by subterranean corridors on four levels.

The  simplest organs consist of a single  rank of pipes, each corresponding to  a single key. They are arranged over  a wind chest connected to the keys  by a set of valves and fed with a sup�  ply of air by electrically or mechani�  cally activated bellows. By pulling  out knobs, called stops, the player  engages new ranks of pipes. Two dis�  tinct types of pipes are used: flue  pipes (both open and stopped) pro�  duce sound by directing air against  the edge of an opening in the pipe,  whereas reed pipes sound by means  of a thin metal tongue inside the pipe  that vibrates against a fixed projec�  tion next to it. A large organ may  have five or more banked keyboards,  or manuals, each of which controls a distinctive group of pipes. Most  organs also have pedalboards played with the feet. A large organ�s pipes  may vary in length from about 1 in. to 32 ft (2.5 cm to 10 m), resulting  in a huge nine-octave range. The earliest organ (c. 250 bc) was the Greek  hydraulis, in which the wind was regulated by water pressure. The  bellows-fed organ appeared about the 7th century ad. The organ became  firmly associated with the church by the 10th century. As organs became  widespread, different regions pursued different modes of construction and  sought different tonal ideals. The Baroque German organ is ideally suited  to polyphony, while the French taste for variety of timbres eventuated in  Aristide Cavaille-Coll�s vast �orchestral� organs.

With an area of 330,689 acres (133,929 hectares), it preserves seg�  ments of the mountainous Sonoran Desert and is named for the organ-  pipe cactus. Wildlife includes Gila monsters, antelope, coyotes, and a  variety of birds.</p><p>organic compound Substance whose molecules contain one or more  (often many more) carbon atoms (excluding carbonates, cyanides, car�  bides, and a few others; see inorganic compound). Until 1828 (see urea),  scientists believed that organic compounds could be formed only by life  processes (hence the name). Since carbon has a far greater tendency to  form molecular chains and rings than do other elements, its compounds  are vastly more numerous (many millions have been described) than all  others known. Living organisms consist mostly of water and organic com�  pounds: PROTEINS, CARBOHYDRATES, FATS, NUCLEIC ACIDS, HORMONES, VITAMINS, and  a host of others. Natural and synthetic fibres and most fuels, drugs, and  plastics are organic. Hydrocarbons contain only carbon and hydrogen;  organic compounds with other functional groups include carboxylic acids,  alcohols, aldehydes, ketones, phenols, ethers, esters, and other, more com�  plex, molecules, including heterocyclic compounds, isoprenoids, and amino</p><p>ACIDS.</p><p>organic farming or organic gardening System of crop cultiva�  tion that uses biological methods of fertilization and pest control as sub�  stitutes for chemical fertilizers and pesticides, which are regarded by  supporters of organic methods as harmful to health and the environment  and unnecessary for successful cultivation. It was initiated as a conscious  rejection of modern agri-chemical techniques in the 1930s by the British  agronomist Sir Albert Howard. Miscellaneous organic materials, includ�  ing animal manure, compost, grass turf, straw, and other crop residues, are  applied to fields to improve both soil structure and moisture-holding  capacity and to nourish soil life, which in turn nourishes plants. (Chemi�  cal fertilizers, by contrast, feed plants directly.) Biological pest control is  achieved through preventive methods, including diversified farming, crop  rotation, the planting of pest-deterrent species, and the use of integrated</p><p>pest management techniques. Bioengineered strains are avoided. Since  organic farming is time-consuming, organically grown produce tends to  be expensive. Organic produce formerly accounted for a minuscule por�  tion of total American farm output, but it has seen a huge proportional  increase in sales in recent years.</p><p>Organization for Economic Cooperation and Develop�  ment See Organization for Economic Cooperation and Development</p><p>Organization of African Unity (OAU) See African Union</p><p>Organization of American States (OAS) International organiza�  tion formed in 1948 to replace the Pan-American Union.

Such asso�  ciations engage in offenses such as cargo theft, fraud, robbery, kidnapping  for ransom, and the demanding of �protection� payments. Their princi�  pal source of income derives from the supply of illegal goods and ser�  vices for which there is continuous public demand, such as drugs,  prostitution, �loan-sharking� (i.e., the lending of money at extremely high  interest rates), and gambling. They are characterized by a hierarchy of  ranks with assigned responsibilities; the coordination of activities among  subgroups; the division of geographic territory among different associa�  tions; a commitment to total secrecy; efforts to corrupt law-enforcement  authorities; and the use of extreme violence, including murder, against  rival associations, informers, and other enemies. International rings of  smugglers, jewel thieves, and drug traffickers have existed throughout  Europe and Asia, and Sicily and Japan have centuries-old criminal orga�  nizations. In the U.S., organized crime flourished in the 20th century,  especially during the Prohibition era.

The oldest written  organum (c. 900), which evidently reflects a prevailing improvisational  practice, consists of two lines moving simultaneously, note against note,  the added line often paralleling the chant line a fourth or a fifth below.  Later the added line acquired greater melodic individuality and indepen�  dence. Organum consisting of more than one note against each chant note  (florid or melismatic organum) appeared by the early 12th century.

Probably the son of a Christian martyr,  Origen studied philosophy in Alexandria and served as head of its cate�  chetical school for 20 years. He later settled in Palestine and founded a  school of philosophy and theology. He traveled widely as a preacher; he  was imprisoned and tortured during the persecutions of the emperor Decius  in 250 but survived to die several years later. His greatest work, the  Hexapla, is a synopsis of six versions of the Hebrew scriptures. His writ�  ings, influenced by Neoplatonism and Stoicism, stress that providence seeks  to restore all souls to their original blessedness and emphasize the cen�  trality of the Word (Logos) in the cosmos. He held that even Satan was  not beyond repentance and salvation, a view for which he was condemned.  Although attacked as a heretic, Origen remained an influential thinker  throughout late antiquity and the Middle Ages.</p><p>original sin In Christian doctrine, the condition or state of sin into  which each human being is bom, or its origin in Adam�s disobedience to  God when he ate the fruit of the tree of knowledge of good and evil. His  guilt was transmitted to his descendants. Though Genesis describes  Adam�s sufferings as the consequence of his disobedience, it does not  make Adam�s sin hereditary. The main scriptural basis of the doctrine is  found in the writings of St. Paul; St. Augustine helped make humanity�s  sinful nature a central element in orthodox Christian theology. Medieval  theologians continued to explore the issue, and Thomas Aquinas offered a  more optimistic view of human nature in his teachings on original sin  than had Augustine. Martin Luther and John Calvin accepted a more Augus-  tinian understanding, and modern evolutionary theory and biblical source  criticism raised new challenges for the definition of original sin.</p><p>Orinoco X.or-e-'no-koX River Major river, South America. It rises on the  western slopes of the Parima Mountains along the border between Venezu�  ela and Brazil. It flows in a giant arc through Venezuela for about 1,700 mi  (2,740 km) and enters the Atlantic Ocean near the island of Trinidad. It  forms part of the border between Colombia and Venezuela. With its tribu�  taries, it is the northernmost of South America�s four major river systems.  The aquatic fauna include the piranhas and the Orinoco crocodile. The  river basin is largely inhabited by indigenous Indian groups.</p><p>oriole Any songbird of 24 species in the Old World genus Oriolus (fam�  ily Oriolidae) or 30 species in the New World genus Icterus (family Ict-  eridae). Males typically are black and yellow or black and orange, with  some white. Females are less colourful. Orioles are not easily seen but  may be detected by their loud whistling and jarring notes. All are insect  eaters (several species also eat fruit) in woodlands and gardens, chiefly  in warm regions. The only European species is the 9.5-in. (24-cm) golden  oriole ( O . oriolus). Other Oriolus species are found in Africa, Asia, and  Australia. The Baltimore oriole (/. galbula) breeds in North America east  of the Rocky Mountains. See photograph above.</p><p>Orion Xo-'ri-onX In Greek mythology,  a powerful hunter. He was some�  times said to be the son of Poseidon.  He drove the wild beasts out of the  island of Chios and fell in love with  Merope, daughter of the island�s  king. Disapproving of Orion, the  king had him blinded, but his vision  was restored by the rays of the rising  sun. He later went to Crete to live  and hunt with Artemis. Some legends  hold that he was killed by Artemis or  Apollo out of jealousy; another tells  that he was fatally bitten by a scor�  pion. After his death the gods placed  him in the sky as a constellation.</p><p>Orion Xo-'rl-onX Nebula Bright nebula, faintly visible to the unaided  eye in the sword of the hunter�s figure in the constellation Orion. About  1,500 light-years from Earth, it contains hundreds of very hot young stars  clustered about a group of four massive stars known as the Trapezium.  Radiation primarily from these four stars excites the nebula to glow. Dis�  covered in the early 17th century, it was the first nebula to be photo�  graphed (1880).</p><p>Orissa State (pop., 2001 prelim: 36,706,920), eastern India. It lies on  the Bay of Bengal and is bordered by Andhra Pradesh, Chhattisgarh, Jhark�  hand, and West Bengal states. It occupies an area of 60,119 sq mi (155,707  sq km), and its capital is Bhubaneshwar; Cuttack is the largest city. Part  of the ancient kingdom of Kalinga, it was a stronghold of Hinduism before  its conquest by the Afghan rulers of Bengal in 1568, when it became part  of the Mughal Empire. It was ruled by Britain from 1803 until India�s  independence in 1947 and became a state in 1950. Situated in a tropical  savanna that is subject to cyclones, it has a largely rural population, which  is engaged mainly in agriculture. Crops include rice, oilseed, jute, and  sugarcane. It has a rich artistic heritage and contains some of the best  examples of Indian art and architecture.</p><p>Orizaba See Citlaltepetl  Orkhon River See Orhon River</p><p>Orkney Islands Island group (pop., 2001: 19,245), Scotland. Lying  north of the Scottish mainland, it comprises more than 70 islands and islets  and constitutes the Orkney council area. The Orkney Islands, only 20 of  which are inhabited, were the Orcades of ancient Classical literature.  There is much evidence of prehistoric inhabitants. Norse raiders arrived  in the late 8th century ad and colonized the islands in the 9th century.  Thereafter they were ruled by Norway and Denmark until Scotland  annexed them in 1472.

A cousin of Louis XVI, he disapproved of Marie-Antoinette and  lived away from the royal court at Versailles. In 1787 he was exiled to  his estates for challenging the king�s authority. In 1789 he was elected to  the Estates General and soon joined the Third Estate. After joining the  Jacobin Club (1791), he renounced his title of nobility (1792) and accepted  the name Philippe Egalite from the Paris Commune.

A violin prodigy, he became professor of  violin at the Budapest Royal Academy at age 17. In 1921 he went to New  York City, where he played in and conducted a theatre orchestra; he gained  national prominence as conductor of the Minneapolis Symphony Orches�  tra (1931-36). He shared conductorship of the Philadelphia Orchestra  with Leopold Stokowski for two years before becoming sole conductor in  1938, and he led the orchestra until he was made laureate in 1980.  Ormandy shaped the orchestra�s sound by developing the lush, velvety  string colour that became its trademark, and the orchestra made scores of  recordings under him.</p><p>ormolu Vor-mo-.liA (from French dorure d�or moulu, �gilding with gold  paste�) Gold-coloured alloy made up of copper, zinc, and sometimes tin  in various proportions but usually at least 50% copper. It is used in mounts  (ornaments on borders, edges, and as angle guards) for furniture and for  other decorative purposes. After the molten alloy has been poured into a  mold and allowed to cool, it is gilded with powdered gold mixed with  mercury. It is then fired at a temperature that evaporates the mercury,  leaving a gold surface. Ormolu was first produced in France in the mid-  nth century, and France remained its main centre of production. See  photograph opposite.</p><p>Ormonde, James Butler, 12th earl and 1st duke of (b.

In service to the English  crown in Ireland from 1633, he fought against the Catholic rebellion from  1641. He concluded a peace with the Catholic confederacy in 1649, then  rallied support for Charles II, but he was forced to flee when Oliver Crom�  well landed at Dublin. He was Charles�s adviser in exile (1650-60). After  the Restoration he was appointed lord lieutenant of Ireland (1662-69,  1677-84), where he encouraged Irish commerce and industry. He was  created a duke in 1682.</p><p>Ormuz See Hormuz</p><p>ornamentation In music, the addition of notes for expressive and  aesthetic purposes. For example, a long note may be ornamented by rep�  etition or by alternation with a neighboring note (�trill�); a skip to a non-  adjacent note can be filled in with the intervening notes; or the resolution  of a dissonance (see consonance and dissonance), because of its inevita�  bility, can be delayed.</p><p>ornamentation In architecture, applied embellishment in various  styles that is a distinguishing characteristic of buildings, furniture, and  household items. Ornamentation often occurs on entablatures, columns,  the tops of buildings, and around entryways and windows, especially in  the form of moldings. Throughout antiquity and into the Renaissance, and  later for religious buildings, applied ornament was very important, often  having symbolic meaning. The anthemion petal motif was especially  popular on the moldings of ancient Greek cornices. Other motifs from  antiquity include the Egyptian cartouche (oval), fretwork (banding) of  capitals, fluting and reeding of columns, bas-relief egg-and-dart moldings  (with alternating oval and pointed forms), and scrollwork such as that  found on Ionic capitals and in the running-dog pattern (or wave scroll).  Brattishing refers to the continuous embellishment around the top of a  wall, common in the Gothic period. The diaper motif, an allover pattern  of small repeated shapes, was also often used in this period. The use of  strapwork (interlaced scrollwork), which originated with Islamic metal�  work, is characteristic of Mannerist architecture and furniture.</p><p>Orne V6m\ River River, northwestern France.

Many species  had a toothless, horny beak and powerful cheek teeth. Omithischians  flourished from the Late Triassic to the Late Cretaceous Epoch (227-65  million years ago). Many species (in the suborder Cerapoda) were bipe�  dal and had ornate skull structures. Some were quadrupedal, with a mas�  sive head culminating in a great bony frill. Other quadrupeds (in the  suborder Thyreophora) had small heads and were heavily plated and  armoured along the back, and some had armour on the flanks and head  as well. See also protoceratops; saurischian; stegosaur; triceratops.</p><p>ornithology Branch of zoology dealing with the study of birds. Early  writings on birds were largely anecdotal (including folklore) or practical  (e.g., treatises on falconry and game-bird management). From the mid-  18th century on, ornithology progressed from the description and classi�  fication of new species discovered in scientific expeditions to the  examination of internal anatomy to the study of bird ecology and ethology.  Ornithology is one of the few scientific fields in which nonprofessionals  make substantial contributions; the field observations of birders provide</p><p>valuable information on behaviour,  ecology, distribution, and migration.  Other information is gained by  means of radar, radio transmitters,  portable audio equipment, and bird  banding, which provides information  on longevity and movements.</p><p>orogeny \6-'ra-jo-ne\ Mountain�  building event, generally one that  occurs in a geosyncline. Orogeny  tends to occur during a relatively  short geologic time frame. It is usu�  ally accompanied by folding and  faulting of strata and by the deposi�  tion of sediments in areas adjacent to  the orogenic belt. Orogenies may  result from continental collisions, the  underthrusting of continents by oce�  anic plates, the overriding of oceanic  ridges by continents, and other  causes.

Sept. 7, 1949, Mexico City) Mexican mural painter.  When he lost his left hand at 17, he abandoned architectural studies for  painting, pursuing Mexican themes. As a caricaturist for a revolutionary  paper, he explored Mexico City�s slums and painted a series of waterco�  lours, House of Tears, on the lives of prostitutes. The reaction of moral�  ists forced him to flee to the U.S. in 1917, but in 1919 the new government  of Alvaro Obregon welcomed him back, and he joined Diego Rivera and  David Alfaro Siqueiros in creating large-scale murals for public buildings,  in which he continued his radical social commentary. Again forced to  abandon Mexico in 1927, he worked until 1934 in the U.S., where his  style evolved and matured in murals from coast to coast. In 1934, his  international reputation firmly established, he returned to Mexico and  embarked on his most technically impressive and emotionally expressive  murals, including Catharsis (1934), in the Palacio de Bellas Artes. He  was a leader among those who raised Mexican art to a position of inter�  national eminence.</p><p>Orpheus Greek legendary hero who sang and played the lyre so beauti�  fully that animals, trees, and rocks danced around him. When his wife,  Eurydice, was killed by a snake, he went to the underworld in search of her,  and his music and grief so moved Hades that he agreed to let Orpheus take  Eurydice back to the land of the living on the condition that neither of them  look back as they left. On seeing the Sun, Orpheus turned to share his  delight with Eurydice, and she disappeared. Orpheus was later torn to  pieces by maenads, and his head, still singing, floated to Lesbos, where an  oracle of Orpheus was established. By the 5th century bc, a Hellenistic mys�  tery religion (the Orphic mysteries), based on Orpheus�s songs and teach�  ings, had arisen. His story became the subject of some of the earliest operas.</p><p>Orphic mysteries See mystery religions</p><p>Orphism Trend in Cubism that gave priority to colour.

Though influenced by Neo- Kantianism, he diverged from it in works such  as Adam in Paradise (1910), Quixote�s Meditations (1914), and Modern  Theme (1923). He saw individual life as the fundamental reality; for abso�  lute reason he substituted reason as a function of life; for absolute truth  he substituted the perspective of each individual. Sharing his generation�s  preoccupation with Spain�s problems, he founded the periodicals Espaha  (1915), El sol (1917), and Revista de Occidente (1923). Of his other  works, the best known are Invertebrate Spain (1922) and The Revolt of  the Masses (1929), which foreshadowed the Spanish Civil War.

His  most famous works are the anti-  Soviet satirical fable Animal Farm  (1945) and Nineteen Eighty-four  (1949), a dystopic vision of totali�  tarianism whose influence was  widely felt in the postwar decades.  His literary essays are also admired.</p><p>oryx Any of four species (genus  Oryx) of large stocky antelopes living  in herds on African and Arabian  deserts and plains. Oryxes are 40^-7  in. (102-120 cm) high. They have a  mane and a tufted tail. The coat is  grayish brown, whitish, or white,  depending on the species, with dark  patches on the face and forehead, a  dark streak on either side of the eye,</p><p>Arabian oryx (Oryx leucoryx)</p><p>ROD MOON-THE NATIONAL AUDUBON SOCIETY  COLLECTION/PHOTO RESEARCHERS</p><p>Osborne, John (James) (b. Dec. 12, 1929, London, Eng.�d. Dec.  24, 1994, Shropshire) British play�  wright and film producer. Initially an  actor, he cowrote his first play. The  Devil Inside Him (1950), with Stella  Linden. His Look Back in Anger  (1956; film, 1959) ushered in a spate  of vigorously realistic plays about  contemporary British working-class  life, making Osborne the first of the  postwar Angry Young Men. His next  play, The Entertainer (1957; film,</p><p>1960), told the story of a failing  music-hall comedian; it was com�  missioned by the actor Laurence Oliv�  ier, who starred in the stage and film  versions. Osborne wrote the screen�  play for the film Tom Jones (1963,</p><p>Academy Award), and his other  plays include Luther (1961) and  Inadmissible Evidence (1964).</p><p>Oscan \'as-kon\ language Italic  anguage formerly spoken in south�  ern and central Italy, related closely  to Umbrian and more distantly to  Latin. It was probably the native  tongue of the Samnite people of Ita�  ly�s central mountainous region.  Oscan was gradually displaced by  Latin and apparently became extinct  by the end of the 1st century ad.  Modem knowledge of it comes from  some 250 inscriptions written in a  colonial Latin alphabet, the Greek  alphabet, and an alphabet derived  from that used for Etruscan.</p><p>Osceola \,a-se-'6-l3\ (b. c. 1804,  Georgia, U.S.�d.

A pendulum is a simple mechanical oscillator that  swings with a constant amplitude, requiring the addition of energy at each  swing only to compensate for the energy lost because of air resistance or  friction. In electronic oscillators, electrons oscillate with a constant period  and also require the addition of energy to replace energy loss. Electronic  oscillators are used to generate alternating current and high-frequency  currents for carrier waves in radio broadcasting. They are incorporated in  a wide variety of electronic equipment.</p><p>oscilloscope \3-'si-l3-,skop\ or cathode-ray oscilloscope Elec�  tronic display device used to produce patterns on a screen that are the  graphical representations of electrical signals. Time is normally on the  horizontal axis, and a function of the voltage generated by the input sig�  nal to the oscilloscope on the vertical axis; four or more plots can be  simultaneously shown. Because almost any physical phenomenon can be  converted into a corresponding electric voltage, oscilloscopes find com�  mercial, engineering, and scientific applications in acoustic research,  television-production engineering, and electronics design.</p><p>Oshogbo \5-'shog-bo\ City (pop., 1996 est.: 476,800), Nigeria. Located  northeast of Ibadan, it lies along the Oshun River. Originally settled by  the Ilesha from Ibokun, it remained a small town until the early 19th cen�  tury when an influx of Yoruba fleeing from Fulani conquerors arrived. In  1840 it was the scene of a battle won by Ibadan that proved to be the  turning point in the Fulani-Yoruba wars. It was made part of Oyo state in  1976 and the capital of the newly created state of Osun in 1991. It is a  trade centre for cocoa and palm oil; weaving and dyeing cotton cloth and  growing tobacco are other local occupations.</p><p>Osiris \o-'sI-r3s\ Ancient Egyptian god of the underworld. Osiris was  slain by the god Seth, who tore apart the corpse and flung the pieces all  over Egypt. The goddess Isis, consort of Osiris, and her sister Nephthys  found the pieces and gave new life to Osiris, who became the ruler of the  underworld. Isis and Osiris then conceived Horus. In the Egyptian con�  cept of divine kingship, the king at death became Osiris and the new king  was identified with Horus. Osiris also represented the power that brought  life out of the earth. Festivals reenacting his fate were celebrated annu�  ally in towns throughout Egypt.</p><p>Osier Vos-lorV, Sir William (b. July 12, 1849, Bond Head, Canada  West, Can.�d. Dec. 29, 1919,</p><p>Oxford, Oxfordshire, Eng.) Cana�  dian physician and professor. He  became the first to identify blood  platelets (1873) and later taught at the  medical school at McGill University  (1875-84) and then at Johns Hop�  kins University�s medical school  (1889-1905). There he helped trans�  form clinical teaching; students stud�  ied patients in the wards and took  their problems to the lab, and experts  pooled their knowledge to benefit  both patient and student in public  teaching sessions. Osier�s Principles  and Practice of Medicine (1892)  became the most popular medical  textbook of its day. He was involved  in the formation of two physicians�  associations and the Quarterly Jour�  nal of Medicine. Osier nodes on the  hand are seen in some cardiac infec�  tions, and two blood disorders also  bear his name.</p><p>Oslo \'az-lo,\ Norwegian Vus-lu\  formerly (1624-1925) Christiania City and municipality (pop., 2002  est.: municipality, 512,589), capital of Norway. It lies at the northern end  of Oslo Fjord and constitutes a separate county. It was founded by King  Harald III Sigurdsson c. 1050. Haakon V built the Akershus fortress c.  1300. After it was destroyed by fire in 1624, King Christian II of Denmark-</p><p>Norway built a new town farther west and called it Christiania. It grew  in the 19th century, partly by absorbing neighbouring towns, and replaced  Bergen as Norway�s largest and most influential city. It was renamed Oslo  in 1925 and developed rapidly after World War II. It is the country�s prin�  cipal commercial, industrial, and transportation centre, and its harbour is  the largest and busiest in Norway.</p><p>osmosis \az-'mo-s3s\ Spontaneous passage or diffusion of water or other  solvent through a semipermeable membrane. If a solution is separated  from a pure solvent by a membrane that is permeable to the solvent but  not to the solute, the solution will tend to become more dilute by absorb�  ing solvent through the membrane. The pressure caused by the migration  of solvent through the membrane is called osmotic pressure.</p><p>osprey Vas-pre, 'as-pra\ or fish hawk Species (Pandion haliaetus ) of  long-winged hawk found along seacoasts and large interior waterways.  Ospreys are about 26 in. (65 cm) long and brown above and white below,  with some white on the head. An osprey flies over the water, hovers above  its prey, and then plunges feet first, seizing the fish in its long, curved  talons. Ospreys breed on all continents except South America, where they  live only in winter. They usually nest, singly or in colonies, high in trees  or on cliffs. Bioaccumulation of pesticides caused populations to dwindle  in the 20th century, but they are now recovering.</p><p>Osroene or Osrhoene \,az-r3-'we-ne\ Ancient kingdom, northwest�  ern Mesopotamia. Located between the Tigris and Euphrates rivers, it was  situated across the modem frontier of Turkey and Syria, with its capital  at Edessa (modem Sanliurfa, Tur.). Founded in c. 136 bc, it commanded  strategic trade and military routes (1st century BC-2nd century ad). At dif�  ferent times it was allied with either Parthia or Rome. The kingdom was  abolished by the Roman emperor Caracalla in ad 216. In the 4th-7th cen�  turies ad it was dominated by the wars between the Byzantine Empire and  the Persian Sasanian dynasty. Under various Arab dynasties, it became a  centre of reaction against Hellenism and the headquarters of Chaldean  Syriac literature and learning. It fell to the Muslims in 638.</p><p>OSS See Office of Strategic Services</p><p>Osservatore Romano yo-.ser-va-'to-ra-ro-'ma-noV 1/ Italian "The  Roman Observer" Daily newspaper published in Vatican City, one of  the most influential papers in Italy and the de facto voice of the Holy See.  Founded in 1861, it was subsidized by the Vatican from its start and was  bought outright in 1890 by Pope Leo XIII. It regularly details the pope�s  activities and prints the text of papal speeches as the Vatican newspaper  of record; it also reports and comments on political developments, stress�  ing editorials and commentary over news and noting the religious and  moral implications of events, institutions, and trends.</p><p>Ossian Vas-e-on, 'ash-on \ Gaelic Oisin Vosh-yin\ Irish warrior-poet of  the Fenian cycle of hero tales. The name Ossian became known throughout  Europe in 1762-63 when the Scottish poet James Macpherson (1736-96)  published the epics Fingal and Temora, which he represented as transla�  tions of works by the 3rd-century Gaelic poet Ossian. The poems were  widely acclaimed and influential in the Romantic movement, but their  authorship was later doubted, notably by Samuel Johnson (1775), and they  were eventually determined to have been written largely by Macpherson.</p><p>Ossianic ballads \,a-se-'a-nik, .a-she-'a-nikX Irish Gaelic and Scottish  lyric and narrative poems dealing with the legendary Finn MacCumhaill  and his war band. They are named for Oisfn (Ossian), the chief bard of  the Fenian cycle. Part of a common Scots-Irish Gaelic tradition, the bal�  lads consist of more than 80,000 lines dating from the 11th to the 18th  century. Unlike earlier Fenian literature, which reflected mutual respect  between pagan and Christian tradition, they are stubbornly pagan and  anticlerical, full of lament for past glories and contempt for the Christian  present. Most of the poetry claimed for Oisfn was in fact written by Scot�  tish poet James Macpherson (1736-1796).</p><p>Ossianic cycle See Fenian cycle</p><p>Ossory \'a-so-re\ Ancient kingdom, Ireland. It became a semi�  independent state within the kingdom of Leinster (c. 1st century ad). In  the 9th century its king, Cerball, allied himself with the Norse invaders.  His Irish descendants became known as the Fitzpatricks. The modem dio�  cese of Ossory, with its see at Kilkenny, approximates the size of the  ancient state.</p><p>Ostade \os-'ta-d3\, Adriaen van (b.

The most important influence on  his style was the work of Adriaen Brouwer. Like Brouwer, he delighted  in scenes such as tavern brawls, usually in dimly lit interiors, as in Carous�  ing Peasants in an Interior (c. 1638). He employed a broad, vigorous  technique in a subdued range of colours. After he adopted a brighter pal�  ette in the 1640s, his subjects became less ribald, and from the 1650s he  painted many of them in outdoor settings.</p><p>Ostend \a-�stend\ Manifesto (1854) Secret document written by U.S.  diplomats at Ostend, Belg., describing a plan to acquire Cuba from Spain.  On orders from U.S. secretary of state William Marcy, three U.S.  diplomats�minister to Britain James Buchanan, minister to France John  Y. Mason, and minister to Spain Pierre Soule�devised a plan to purchase  or, if necessary, seize Cuba for the U.S. Publication of the aggressively  worded document, and Soule�s advocacy of slavery, caused Marcy to  denounce it.</p><p>osteoarthritis V.as-te-o-ar-'thri-tosX or osteoarthrosis or degen�  erative joint disease Most common joint disorder, afflicting over  80% of those who reach age 70. It does not involve excessive inflamma�  tion and may have no symptoms, especially at first. Cartilage softens and  wears away, and bone grows in its place, distorting the joint�s surface and  causing pain, stiffness, and limited movement, usually in weight-bearing  joints (vertebrae, knees, hips). Treatment may include analgesics, rest,  weight loss, corticosteroids, and/or physical medicine and rehabilitation or an  exercise program. Hip or knee replacement or surgical removal of  unhealthy tissue may be needed.</p><p>osteogenesis imperfecta V.as-te-o-'je-no-sos-.im-por-'fek-toN Group  of connective-tissue diseases in which the bones are very fragile. Several  forms probably reflect different degrees of expression of the same disor�  der. Persons with osteogenesis imperfecta type I are normal at birth, but  fractures occur easily; in van der Hoeve syndrome the sclerae are bluish,  bone deformities in the skull cause deafness, double-jointedness occurs,  and skin is abnormally thin. Babies with osteogenesis imperfecta type II,  if not stillborn, are born with fractures, and fractures continue to occur,  causing severe crippling; survival to adulthood is rare.</p><p>osteopathy \,as-te-'a-p3-the\ Health-care profession founded by the  U.S. physician Andrew Taylor Still (1828-1917) as a reform movement  against the rather primitive 19th-century drugs and surgical techniques.  It emphasizes the relationship between musculoskeletal structure and  organ function. Osteopathic physicians learn to recognize and correct  structural problems through manipulative and other therapies. Osteopathic  hospitals provide general or specialized health care, including maternity  and emergency care.</p><p>osteoporosis \,as-te-6-p3-'ro-s9s\ Generalized loss of bone density,  causing skeletal weakness. Around age 40, the rate of bone resorption in  humans starts to exceed the rate of bone formation. Women experience  accelerated bone loss after menopause, when the estrogen level decreases.  When the amount of bone falls below a certain threshold, fractures occur  with little or no trauma. Prevention begins with adequate calcium intake  in youth, when bone mass is built, and then throughout life. Weight�  bearing exercise and vitamin D are important at all ages. Medications can  inhibit bone resorption or prevent bone loss in patients who are at risk for  developing osteoporosis.</p><p>Ostia \'a-ste-o\ Ancient Roman town. Originally at the mouth of the Tiber  River, it would now be about 4 mi (6 km) upstream. The modern seaside  resort of Ostia, Italy, is near the ancient city. It was probably founded in  the 4th century bc and developed as a naval station, major port, and cen�  tre of the grain trade. It reached the height of its prosperity in the 2nd  century ad, when it had a population of about 50,000. It suffered from the  decline of the Roman economy in the 3rd century and from barbarian raids  in the 5th century. Its Roman ruins were quarried for building materials  in the Middle Ages and for sculptors� marble during the Renaissance.  Excavations began in the 19th century, and about two-thirds of the Roman  town can now be seen.</p><p>ostomy Vas-t3-me\ Surgical opening in the body, or the operation cre�  ating it, usually to allow discharge of wastes through the abdominal wall.  It may be temporary, to relieve strain on damaged organs, or permanent,  to replace normal channels congenitally missing or surgically removed  (usually to treat cancer). A loop of bowel (the colon in colostomy and the  ileum in ileostomy) is cut and the end brought through to the abdominal</p><p>surface. Waste usually exits into a self-adhering bag worn over the open�  ing, or an internal pouch may be made from body tissue.</p><p>Ostpolitik Vost-po-li-.tekX (German: �Eastern Policy�) West German  foreign policy begun in the late 1960s. Initiated by Willy Brandt as for�  eign minister and then chancellor, the policy was one of detente with  Soviet-bloc countries, recognizing the East German government and  expanding commercial relations with other Soviet-bloc countries. Trea�  ties were concluded in 1970 with the Soviet Union, renouncing the use  of force in their relations, and with Poland, recognizing Germany�s 1945  losses east of the Oder-Neisse Line. The policy was continued by Chancel�  lor Helmut Schmidt.</p><p>Ostrasia See Austrasia</p><p>Ostrava Vo-stro-vsX City (pop., 2001 prelim.: 319,293), northeastern  Czech Republic, at the confluence of the Opava and Oder rivers near the  Moravian Gap. It was founded c. 1267 as a fortified town by Bruno,  bishop of Olomouc, to protect the entry to Moravia from the north. Its  castle was demolished in 1495. Historic buildings include a 13th-century  church.</p><p>ostrich Two-toed, long-necked ratite ( Struthio camelus, family  Struthionidae) found in Africa, the largest living bird. An adult male  ostrich may be nearly 9 ft (2.75 m) tall and weigh more than 330 lb (150  kg). Males are black, with white wing and tail plumes; females are brown.  Ostriches live in flocks of 5-50, usually among grazing animals, and eat  plants and an occasional small animal. Roaring, hissing males fight for  three to five hens, which lay 15-60 eggs in a communal nest scraped in  the ground. The male sits at night; the females take turns by day. One-  month-old chicks can run with adults, at 40 mph (65 km/hr). To escape  detection, an ostrich may lie on the ground with its neck outstretched, a  habit that may have given rise to the notion that ostriches bury their heads  in the sand.</p><p>Ostrogoth Vas-tro-.gathV Member of a division of the Goths (Ostrogoth  means �Eastern Goth�) who built an empire north of the Black Sea in the  3rd century and established a kingdom in Italy in the late 5th century. At its  zenith in the 4th century, the Ostrogoth empire stretched from the Don to  the Dniester (in present-day Ukraine) and from the Black Sea to southern  Belarus. The Ostrogoths were conquered by the Huns c. 370 and remained  part of the Huns� empire until the mid 5th century. When the Hun empire  collapsed (455), the Ostrogoths emerged as an independent people once  again. Their greatest ruler, Theodoric, led the Ostrogothic invasion of Italy  and declared himself king (493). Theodoric maintained good relations with  the native population, especially the senatorial class, throughout most of  his reign and promoted a cultural revival. The turmoil in Italy following his  death provided the Byzantine emperor Justinian I with the opportunity to  invade the peninsula. The ensuing war lasted almost 20 years (c. 535-54)  and ended the national existence of the Ostrogoths.</p><p>Ostrovsky V.o-'strof-skeV, Aleksandr (Nikolayevich) (b. April  12, 1823, Moscow, Russia�d. June 14, 1886, Shchelykovo) Russian  playwright. His second play, The Bankrupt (1850), exposed bogus bank�  ruptcy cases and led to his dismissal from the civil service. Most of his  plays treat characters from the Russian merchant class; they include the  comedies Poverty Is No Disgrace (1853), The Thunderstorm (1859), and  The Snow Maiden (1873), adapted as an opera by Nikolay Rimsky-  Korsakov. With his 47 plays Ostrovsky created a Russian national reper�  toire, and he is considered the greatest representative of the Russian  realistic period.</p><p>Ostwald \'6st-,valt\, (Friedrich) Wilhelm (b. Sept. 2, 1853, Riga,  Latvia�d. April 4, 1932, near Leipzig, Ger.) Russian-German physical  chemist. He moved to Germany in 1887. He wrote the influential Text�  book of General Chemistry, 2 vol. (1885-87). With Jacobus H. van't Hoff  in 1887 he founded the Zeitschrift fur physikalische Chemie, which  became for many years the most important journal in the field. His work  at the University of Leipzig (1887-1906) established it as a great school  of physical chemistry. In 1888 he discovered Ostwald�s law of dilution of  an electrolyte. He gave the first modem definition of a catalyst in 1894  and was awarded the Nobel Prize in 1909 for his work on catalysis. His  process for the conversion of ammonia to nitric acid proved of great  industrial importance. He is regarded as one of the founders of the field  of physical chemistry.</p><p>O'Sullivan, Timothy H. (b. c. 1840, New York, N.Y., U.S.�d. Jan.  14, 1882, Staten Island, N.Y.) U.S. photographer. He learned photogra-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Oswald &#x25BA; otter I 1423</p><p>phy in Mathew B. Brady�s studio in New York City, and during the Ameri�  can Civil War he photographed on many fronts as one of Brady�s team.  Perhaps his best-known picture is Harvest of Death (1863), showing Con�  federate dead at Gettysburg. O�Sullivan left Brady�s employ over the issue  of receiving proper credit for his work. After the war O�Sullivan often  portrayed vast landscapes. He took part in surveys in Panama as well as  in the western and southwestern U.S. and was appointed chief photogra�  pher for the Treasury Department in 1880.</p><p>Oswald, Lee Harvey (b. Oct. 18, 1939, New Orleans, La., U.S.�d.  Nov. 24, 1963, Dallas, Texas) Accused assassin of Pres. John F. Kennedy.  While serving in the U.S. Marines (1956-59) he began to express pro-  Soviet and politically radical views. Shortly after his discharge he moved  to the Soviet Union, where he unsuccessfully tried to become a Soviet  citizen. He returned to the U.S. in 1962 with his Russian wife and daugh�  ter but retained his radical political beliefs. In April 1963 he allegedly  shot at but missed Edwin Walker, an ultrarightist retired general. In Octo�  ber he took a job at the Texas School Book Depository in Dallas. On Nov.  22, 1963, from a window on its sixth floor, he allegedly fired three shots  that killed Kennedy and wounded Gov. John B. Connally while the two  men were riding in the president�s motorcade. Oswald killed a patrolman  who had detained him, but he was soon captured and arraigned. On  November 24, while being transferred to an interrogation office, he was  fatally shot by Jack Ruby, a nightclub owner.</p><p>other minds, problem of In epistemology, the problem of explain�  ing how it is possible for one person to know anything about the quality  of another person�s inner experience, or even that other people have inner  experiences at all. According to a standard example, because each per�  son�s pain sensation is private, one cannot really know that what another  person describes as pain is really qualitatively the same as what one  describes as pain oneself. Though the physical manifestations the other  person exhibits can be perceived, it seems that only the other person can  know the contents of his mind. The traditional justification for belief in  other minds, the argument from analogy, was given its classic formula�  tion by John Stuart Mill: because my body and outward behaviour are  observably similar to the bodies and behaviour of others, I am justified  by analogy in believing that others have feelings like my own and are not  simply automatons. In the mid-20th century the argument from analogy  was severely criticized by followers of the later Ludwig Wittgenstein. An  approach to the problem of other minds from the perspective of existen�  tialism is contained in Being and Nothingness (1943), by Jean-Paul Sartre.</p><p>Otis, Harrison Gray (b.

A nephew of James Otis, he  practiced law and served in the Massachusetts legislature (1796-97,  1802-05), the U.S. House of Representatives (1797-1801), the state sen�  ate (1805�13, 1814-17), and the U.S. Senate (1817-22). He was later  mayor of Boston (1829-32). A Federalist, he opposed the War of 1812  and was a leader of the Hartford Convention.</p><p>Otis, James (b. Feb. 5,1725, West Barnstable, Mass.�d. May 23,1783,  Andover, Mass., U.S.) American Revolutionary statesman. He argued  before the colonial court against the British-imposed writs of assistance  (1761), reportedly stating �Taxation without representation is tyranny.�� He  served in the provincial legislature (1761-69) and was a leading opponent,  along with Samuel Adams, of the Stamp Act. He wrote political pamphlets  upholding the colonists� cause, including The Rights of the British Colonies  Asserted and Proved (1764). Struck on the head in a scuffle with a British  official in 1769, he later became mentally unbalanced.</p><p>otitis \o-'tI-t9s\ Inflammation of the ear. Otitis externa is dermatitis, usu�  ally bacterial, of the auditory canal and sometimes the external ear. It can  cause a foul discharge, pain, fever, and sporadic deafness. Otitis media is  due to allergy or viral or bacterial infection of the middle ear. The bac�  terial form may be acute (causing earache, fever, and pus and requiring  antibiotics) or chronic. It can invade the bone (mastoiditis), requiring sur�  gery. Otitis in the inner ear (labyrinthitis) often arises from respiratory  infection, syphilis, or otitis media. Symptoms include vertigo, vomiting,  and hearing loss. Recovery is usually quick unless there is pus formation,  which can destroy the inner-ear structures, causing permanent deafness in  that ear.</p><p>otolaryngology V.o-to-.lar-on-'ga-lo-jeV or otorhinolaryngology</p><p>X.o-to-.rl-no-.lar-on-'ga-lo-jeV Medical specialty dealing with the ear, nose,  and throat (see larynx, pharynx). The connection of these structures became  known in the late 19th century. Otolaryngologists use an otoscope to</p><p>examine the eardrum and a laryngoscope (developed in 1855) to inspect  the larynx. They also test hearing and prescribe hearing aids. The oper�  ating microscope (developed in 1921) and flexible endoscopy now permit  them to operate on delicate internal structures.</p><p>Otomanguean \,o-t3-'maq-ga-3n\ languages Diverse family of  more than 20 American Indian languages and language clusters concen�  trated in central and southern Mexico, with more than a million speak�  ers. Several of the language clusters, such as Otomf (dispersed through  eastern central Mexico), Chinantecan, Mixtecan, and Zapotecan (all spo�  ken in the state of Oaxaca), are highly differentiated and may be consid�  ered language families in themselves.

He studied drama at the Royal Academy of Dra�  matic Art. He made his London debut in 1956 and played Hamlet in the  National Theatre�s inaugural production in 1963. His film debut came in  Kidnapped ( 1960), and he won international acclaim for Lawrence of Ara�  bia (1962), for which he won a British Academy Award. Noted for his wit  and intensity, he often played uncertain heroes or eccentrics, starring in  films such as Becket (1964), The Lion in Winter (1968), The Ruling Class  (1972), The Stunt Man (1980), My Favorite Year (1982), The Last Emperor  (1987), and Phantoms (1998). His acting range extends from classical  drama to contemporary farce. He received an Emmy Award for his perfor�  mance as Bishop Cauchon in the television miniseries Joan of Arc (1999).</p><p>otorhinolaryngology See otolaryngology</p><p>ottava rima Xo-'ta-vo-'re-moV Italian stanza form composed of eight  11-syllable lines, rhyming abababcc. It originated in the late 13th and  early 14th centuries and was established by Giovanni Boccaccio as the  standard form for Italian epic and narrative verse. When the form appeared  in English, the lines were shortened to 10 syllables. In the 17th�18th cen�  tury, English ottava rima was written in iambic pentameter and used for  heroic poetry. Notably effective in Lord Byron�s Beppo (1818) and Don  Juan (1819-24), it was also used by Edmund Spenser, John Milton, John  Keats, Percy B. Shelley, Robert Browning, and William Butler Yeats.</p><p>Ottawa Va-to-woV City (pop., 2001: 774,072), capital of Canada. It is  located in southeastern Ontario, on the Ottawa, Gatineau, and Rideau  rivers. The area was inhabited by American Indians when it was visited  by Samuel de Champlain in 1613, and the nearby rivers served traders and  explorers over the next two centuries. Its settlement developed after the  construction of the Rideau Canal in 1826. Originally named Bytown, it  was incorporated as the city of Ottawa in 1855. To resolve political dis�  putes between Toronto and Quebec City and between Montreal and Kings�  ton, it was selected as Canada�s capital by Queen Victoria in 1857. In  2001 the city�s population grew significantly after it was amalgamated  with several local municipalities. The federal government is the major  employer; many commercial and financial associations are also located  there. It is the site of several educational and cultural institutions, includ�  ing the National Arts Centre and the National Gallery of Canada.</p><p>Ottawa River River, eastern central Canada, the chief tributary of the  St. Lawrence River. It rises in the Laurentian plateau of western Quebec and  flows west to form the Quebec-Ontario border before joining the St.  Lawrence west of Montreal. It is 790 mi (1,271 km) long and forms innu�  merable lakes. Explored by Samuel de Champlain in 1613, it became a major  route for explorers, fur traders, and missionaries to the Great Lakes. In the  19th century the Rideau Canal was completed, linking Ottawa to Lake  Ontario, and lumbering became important.

May 7, 973,</p><p>Memleben, Thuringia) Duke of Sax�  ony (936-61), German king (936-  73), and emperor (962-73). He extended the frontiers of the German  kingdom, winning territory from the Slavs in the east, forcing the Bohe�  mians to pay tribute (950), and gaining influence in Denmark and Bur�  gundy. In 951 Otto became king of the Lombards and married the queen  of Italy. He quelled a rebellion by his son in 955 and defeated the Mag�  yars in the Battle of Lechfeld. Crowned emperor by Pope John XII in 962,  he deposed John in 963 and replaced him with Leo VIII. He returned to  Italy (966-72) to subdue Rome, and he betrothed his son, Otto II, to a  Byzantine princess (972). He also extended his authority over the church  and promoted missionary activity in lands he had conquered. By his death,  Otto had created the most powerful state in western Europe and laid the  foundation for the later Holy Roman Empire.</p><p>Otto III (b. July 980�d. Jan. 23, 1002, near Viterbo, Italy) German king  (983-1002) and emperor (996-1002). He was elected German king at age  3, and his mother and grandmother served as regents until he came of age  in 994. He went to Rome to put down a rebellion (996) and installed his  cousin as Gregory V, the first German pope. After returning in 997 to quell  another revolt, he made Rome the centre of his empire. He saw himself  as leader of world Christianity and hoped to revive the glory of ancient  Rome in a universal Christian state. When Rome rebelled against him  (1001), he requested help from Bavaria but died before it arrived.</p><p>Otto IV or Otto of Brunswick (b. 1175/1182�d. May 19, 1218,  Harzburg Castle, Lower Saxony) German king and Holy Roman emperor.  He was elected German king (1198) by the Guelph faction (see Guelphs  and Ghibellines) but was opposed by the Hohenstaufens, who elected Philip  of Swabia. The two factions were at war for several years, but after Phil�  ip�s murder in 1208 a new election gave the throne to Otto. He was  crowned emperor (1209) by Pope Innocent III after agreeing not to claim  Sicily. When he violated this pact and conquered southern Italy (1210),  the German princes invited Frederick II to replace him. With his uncle, John  of England, Otto invaded France, Frederick�s ally; defeated at the Battle  of Bouvines, he was deposed in 1215.</p><p>religion were influenced by his journeys to Africa and Asia to study non-  Christian faiths and by the writings of Immanuel Kant and Friedrich Schleier-  macher. In The Idea of the Holy (1917), Otto coined the term numinous  to designate the nonrational element of religious experience�the awe,  fascination, and blissful exultation inspired by the perception of the  divine. He believed that religion provided an understanding of the world  that was distinct from and beyond that of science. His other books include  Mysticism East and West (1926), India's Religion of Grace and Chris�  tianity (1930), and The Kingdom of God and Son of Man (1938).</p><p>Ottoman Empire Former empire centred in Anatolia. It was named  for Osman I (1259-1326), a Turkish Muslim prince in Bithynia who con�  quered neighbouring regions once held by the SeuOq dynasty and founded  his own ruling line c. 1300. Ottoman troops first invaded Europe in 1345,  sweeping through the Balkans. Though defeated by Timur in 1402, by 1453  the Ottomans, under Mehmed II (the Conquerer), had destroyed the Byzan�  tine Empire and captured its capital, Constantinople (now Istanbul), which  henceforth served as the Ottoman capital. Under Selim I (r. 1512-20) and  his son SOleyman I (the Magnificent; 1520-66), the Ottoman Empire  reached its greatest peak. Suleyman took control of parts of Persia, most  of Arabia, and large sections of Hungary and the Balkans. By the early  16th century the Ottomans had also defeated the MamlOk dynasty in Syria  and Egypt; and their navy under Barbarossa soon seized control of much  of the Barbary Coast. Beginning with Selim, the Ottoman sultans also held  the title of caliph, the spiritual head of Islam. Ottoman power began to  decline in the late 16th century. Ottoman forces repeatedly besieged  Vienna. After their final effort at taking the Austrian capital failed (1683),  that and subsequent losses led them to relinquish Hungary in 1699. Cor�  ruption and decadence gradually undermined the government. In the late  17th and 18th centuries the Russo-Turkish Wars and wars with Austria and  Poland further weakened the empire, which in the 19th century came to  be called the �sick man of Europe.� Most of its remaining European ter�  ritory was lost in the Balkan Wars (1912-13). It sided with Germany in  World War 1(1914-18); postwar treaties dissolved the empire, and in 1922  the sultanate was abolished by Mustafa Kemal AtatOrk, who proclaimed  the Republic of Turkey the following year.

Though it drew on the  heritage of Carolingian art, it developed a style of its own, particularly  in painting and sculpture. Manuscript illuminators of the period were less  concerned with naturalism than with expression through sober, dramatic  gesture and a heightened use of colour. Ottoman large-scale wooden cru�  cifixes and wooden reliquaries covered with gold leaf marked a return to  sculpture in the round. Bronze casting, an antique art practiced by the  Carolingians, flourished as well. Ottonian architecture was more regulated  than Carolingian, with simple interior spaces and a more systematic lay�  out. Ottonian architects provided impetus for the monumentality of  Romanesque architecture.</p><p>Otway, Thomas (b. March 3, 1652, Trotton, near Midhurst, Sussex,  Eng.�d. April 14, 1685, London) English dramatist and poet. A failed  actor, he turned to writing and had immense success with Don Carlos  (produced 1676), considered the best of his rhymed heroic plays. His other  plays include The Orphan (1680), a blank-verse domestic tragedy; The  Souldier�s Fortune (1680), a comedy; and his masterpiece, Venice  Preserv�d (1682), one of the greatest theatrical successes of the period.  A forerunner of sentimental drama, he is outstanding for his convincing  presentations of human emotions in an age of heroic but artificial trag�  edies. The Poet�s Complaint of His Muse (1680) is a powerful, gloomy  autobiographical poem.</p><p>Ouachita Vwa-sho-.toX River formerly Washita River River, south�  western Arkansas and eastern Louisiana, U.S. Rising in the Ouachita  Mountains, it flows southeast to join the Red River after a course of 605  mi (973 km).

He served in various official positions but  was repeatedly demoted or banished for his outspokenness. He called him�  self Zuiweng (�Old Drunkard�), built a pavilion of that name, and wrote an  essay about it that is one of the most celebrated works in Chinese literature.  Later put in charge of civil-service examinations, he favoured those who  wrote in the simple, ancient style known as guwen and failed those who  used literary embellishments, thus setting a new course in Chinese litera�  ture. His own writings in the guwen style, including Xintangshu (1060;  �New History of the Tang Dynasty�), became a model that was long emu�  lated. When the Xintangshu was finished, Ouyang was rapidly promoted to  the highest councils of state, leaving a remarkable record in social, finan�  cial, and military affairs. He was falsely accused of having an affair with his  daughter-in-law, a charge that injured his prestige. He repeatedly asked to  be relieved of his duties, but instead he was sent to be magistrate succes�  sively in Anhui, Shandong, and Henan. As the leader of the reform move�  ment of poetry and prose in the Northern Song dynasty, Ouyang established  a monumental reputation by his epoch-marking creative works, and he is  renowned as one of the Eight Great Masters of Tang and Song.</p></section><section><p>ouzel or ousel Vii-zolX Species ( Turdus torquatus) of songbird in the  thrush family, characterized by a  white crescent on the breast.

Human females have two ovaries, almond-shaped organs about  1.5 in. (4 cm) long. They contain hollow balls of cells (follicles) that hold  immature eggs. About 150,000-500,000 follicles usually are present at  birth; by young adulthood, only about 34,000 remain. The number con�  tinues to decrease until menopause, when the few remaining follicles decay  and the ovaries shrink and produce far less estrogen. Only 300-400 fol�  licles mature and release an egg, which develops into an embryo if fertil�  ized or, if not, passes from the body with menstruation. In botany, an ovary  is the enlarged base of a flower�s female organ (pistil). It contains ovules,  which develop into seeds when fertilized, and matures into a fruit.</p><p>over-the-counter market Trading in stocks and bonds that does not  take place on stock exchanges. Such trading occurs most often in the U.S.,  where requirements for listing stocks on the exchanges are strict. Sched�  ules of fees for buying and selling securities are not fixed in the over-the-  counter market, and dealers derive their profits from the markup of their  selling price over the price they paid.

A body producing a musical pitch�such as a taut string or  a column of air within the tubular body of a wind instrument�vibrates  not only as a unit but simultaneously also in sections, resulting in the  presence of a series of overtones within the fundamental tone (i.e., the  one identified as the actual pitch). Harmonics are a series of overtones  resulting when the partial vibrations are of equal sections (e.g., halves,  thirds, fourths). Partials are nonharmonic overtones�that is, tones the  frequencies of which lie outside the harmonic series. Overtones contrib�  ute greatly to the timbre of a given sound source, even though few listen�  ers are aware of hearing any pitch except the fundamental. There are a  few rare examples of the human voice creating overtones, notably in the  chants of the Tibetan monks and the songs of the Tuvan throat singers.  The latter can sometimes produce two overtones.</p><p>overture Musical introduction to a larger, often dramatic, work. Origi�  nating with Claudio Monteverdi�s Orfeo (1607), overtures served as open�  ings for operas. The large-scale two- or three-part �French overture�  invented by Jean-Baptiste Lully (1658) for his operas and ballets was widely  imitated for a century. The sinfonia, the standard Italian overture form in  the late 17th and 18th centuries, was a principal precursor of the three-  part sonata form and thus provided the model for the earliest symphonies,  which consisted of three movements. In the 19th century, overtures inde�  pendent of any larger work usually illustrated a literary or historical theme  (see symphonic poem). Overtures to operettas and musicals have tradition�  ally been medleys of their themes.</p><p>Ovett \o-'vet\, Steve in full Stephen Michael Ovett (b. Oct. 9,  1955, Brighton, Sussex, Eng.)

His first work, The Loves, was an imme�  diate success. It was followed by Epistles of the Heroines', The Art of  Beauty', The Art of Love, one of his best-known works; and Remedies for  Love, all reflecting the sophisticated, pleasure-seeking society in which  he moved. He was a well-established poet when he undertook perhaps his  greatest work. Metamorphoses, on legends of transformations of human  beings into nonhuman forms by gods; and Fasti (�Calendar�), an account  of the Roman year and its religious festivals. His verse had immense  influence because of its imaginative interpretations of classical myth and  its supreme technical accomplishment. For unclear reasons, in ad 8 Augus�  tus banished him to Tomis on the Black Sea; despite Ovid�s many pleas,  he was never allowed to return.

In  A New View of Society (1813) he contended that character is wholly  formed by one�s environment. By 1817 his work had evolved into ideas  presaging socialism and the cooperative movement, ideas he would spend  much of his life preaching. He sponsored several experimental utopian  communities of �Owenites� in Britain and the U.S., including one at New  Harmony, Ind.

A week before the armistice, he died in action at age 25. His  single volume of poems, published posthumously, is noted for its experi�  ments in assonance.

Because it forms soluble chelates with iron, some of the iron in these plants  is not available nutritionally. However, this property makes it useful for  removing blood and rust stains, cleaning metals other than iron, and flush�  ing car radiators. Oxalic acid and its salts (oxalates) are used in many  chemical processes.</p><p>oxalis \ak-'sa-l9s\ Any of about 850 species of small herbaceous plants  that make up the genus Oxalis, native mostly to southern Africa and  tropical and South America. Most members are familiar garden ornamen�  tals. The name (Greek for �acid�) reflects the plant�s sharp acidic taste.  The common wood sorrel ( O. acetosella ) of eastern North America and  Britain is a small, stemless plant with cloverlike three-part leaves, whose  leaflets fold back and droop at night. The flowers have five white, purple-  veined petals. After the fruit splits open, the fleshy coat of the seed curls  back elastically, ejecting the true seed.</p><p>oxbow lake Small lake located in a former meander loop of a river or  stream channel. It is generally formed as a river cuts through a meander  neck to shorten its course, blocks off the old channel, and then migrates  away from the lake. If only one loop is cut off, the lake is crescent-shaped;  if more than one loop is cut off, the lake is serpentine (winding). Even�  tually, oxbow lakes silt up to form marshes and finally meander scars.</p><p>Oxenstierna (af Sodermore) Vuk-sen-.sher-naV Axel  (Gustafsson), Count (b. June 16, 1583, Fano, near Uppsala,  Swed.�d. Aug. 28, 1654, Stockholm) Swedish statesman. Born into a  noble family, he became a member of the council of state and in 1612  was appointed chancellor by Gustav II Adolf. He worked with the king to  stabilize administrative reforms. As a diplomat, he negotiated peace trea�  ties with Denmark (1613) and Poland (1622). In the Thirty Years' War, he  was appointed governor-general of Prussia (1626) and military com�  mander in Germany (1631). He directed Swedish policy in Germany until  1636, when he returned to Sweden. As a regent during Queen Christina�s  minority (1636-44), he effectively ruled the country.</p><p>oxeye daisy Garden perennial plant (Chrysanthemum leucanthemum)  in the composite family.

It grows about 2 ft (60 cm) high and has oblong, notched leaves  and long petioles (leafstalks). Native to Europe and Asia, it has become  a common wild plant in the U.S. See also daisy.</p><p>Oxford ancient Oxonia City and administrative district (pop., 2001:  134,248), county seat of Oxfordshire, England. Situated on the River  Thames, the town is best known for the University of Oxford. First occu�  pied in Saxon times as a fording point, it became a burg, built to defend  the northern frontier of Wessex from Danish attack; it was first mentioned  in the Anglo-Saxon Chronicle of ad 912. Little remains of the town�s  Norman period of occupation. Oxford is generally known as the �City of  Spires� because of its skyline of Gothic towers and steeples. Most of these  15th-17th-century buildings belong to the university. The city was the  Royalist headquarters in the English Civil Wars. Its modem economy is  varied and includes, in addition to educational services, printing and pub�  lishing industries and automobile manufacturing.</p><p>Oxford, Earl of See Robert Harley</p><p>Oxford, Edward de Vere, 17th earl of orig. Edward de Vere</p><p>(b. April 12, 1550, Castle Hedingham, Essex, Eng.�d. June 24, 1604,  Newington, Middlesex) English lyric poet. A brilliantly gifted linguist and  one of the most dashing figures of his time, Oxford was also reckless,  hot-tempered, and disastrously spendthrift. He was the patron of an act�  ing company, Oxford�s Men, and possibly later of the Lord Chamberlain's  Men (as hereditary Lord Great Chamberlain of England), as well as of  such writers as John Lyly and Edmund Spenser. He wrote highly praised  poems and plays in his earlier years, though none of the plays are known  to have survived. A 1920 book by J. Thomas Looney made Oxford the</p><p>leading candidate, next to William Shakespeare himself, for the authorship  of Shakespeare�s plays, a theory supported by the coincidence that  Oxford�s literary output apparently ceased just before Shakespeare�s work  began to appear. A major difficulty in the Oxfordian theory, however, is  his death date (1604), because, according to standard chronology, 14 of  Shakespeare�s plays, including many of the most important ones, were  apparently written after that time. The debate, however, remained lively  into the 21st century.</p><p>Oxford, Provisions of (1258) Plan of reform accepted by Henry III  of England. On the verge of bankruptcy, Henry asked Parliament for a  grant of revenue and agreed in return to a program of reform drafted by  a royal commission. Regarded as England�s first written constitution, the  Provisions placed the government under the direction of the king and a  15-member baronial council, provided for Parliament to meet three times  a year, and reformed local administration. They were annulled by the  Dictum of Kenilworth (1266).</p><p>Oxford, University of Autonomous university at Oxford, Oxford�  shire, England. It was founded in the 12th century and modeled on the  University of Paris, with initial faculties of theology, law, medicine, and  the liberal arts. Of the earliest colleges. University College was founded  in 1249, Balliol c. 1263, and Merton in 1264. Early scholars of note  include Roger Bacon, John Duns Scotus, William of Ockham, and John  Wycliffe. In the Renaissance, Desiderius Erasmus and St. Thomas More  helped enhance its already considerable reputation. By then faculties of  physical science, political science, and other fields had been added. The  first women�s college. Lady Margaret Hall, was established in 1878. There  are 32 other colleges and collegial institutions. Oxford houses the Bodlei�  an Library and the Ashmolean Museum of Art and Archaeology. Oxford  University Press (1478) is the world�s oldest, largest, and most famous  university publisher. Oxford has been associated with many of the great�  est names in British history.</p><p>Oxford English Dictionary, The (OED) Definitive historical dic�  tionary of the English language. It was conceived by London�s Philologi�  cal Society in 1857, and sustained editorial work began in 1879 under  James Murray. Published in 10 volumes between 1884 and 1928, it first  appeared under its current name in 1933. Its definitions are arranged  mostly in order of historical occurrence and illustrated with dated quo�  tations from English-language literature and records. Its second edition  was published in 20 volumes in 1989.</p><p>Oxford movement or Praetorian movement (1833^45) Move�  ment within the Church of England that aimed to emphasize the church�s  Catholic inheritance as a source of legitimacy and deeper spirituality. Its  main intent was to defend the Church of England as a divine institution  against the threats of liberal theology, rationalism, and government inter�  ference. Though some in the movement (notably John Henry Newman and  Henry E. Manning) ended up converting to Catholicism, most did not.  Their concern for a higher standard of worship influenced not only the  Church of England but also other British Protestant sects. The movement  was also instrumental in the establishment of Anglican monasteries and  convents.</p><p>Oxfordshire Vaks-fsrd-.shhA Administrative (pop., 2001: 605,492) and  historic county, south-central England. It consists of two upland areas  divided by a broad vale. Evidence of inhabitation dates from the Paleo�  lithic, Mesolithic, and Neolithic periods. Dorchester was an important  Roman settlement; subsequent Saxon settlement was concentrated along  the Thames River valley. The county saw action during the English Civil  Wars. Oxfordshire�s economy is basically agricultural, with sheep farm�  ing and wool production. Cowley, a suburb of the county seat of Oxford,  is the major industrial centre.</p><p>oxidation-reduction or redox Any chemical reaction in which elec�  trons are transferred. Addition of hydrogen or electrons is reduction, and  removal of hydrogen or electrons is oxidation (originally applied to com�  bination with oxygen but now including transfer of hydrogen or electrons).  The processes always occur simultaneously: one substance is oxidized by  the other, which it reduces. The conditions of the substances before and  after are called oxidation states, to which numbers are given and with  which calculations can be made. (Valence is a similar but not identical  concept.) The chemical equation that describes the electron transfer can  be written as two separate half reactions that can in theory be carried out  in separate compartments of an electrolytic cell (see electrolysis), with  electrons flowing through a wire connecting the two. Strong oxidizing</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1428 I oxide &#x25BA; Ozma</p><p>agents include fluorine, ozone, and oxygen itself; strong reducing agents  include alkali metals such as sodium and lithium.</p><p>oxide Any of a large and important class of chemical compounds in  which oxygen is combined with another element. Metal oxides contain a  metal cation and the oxide anion (0 2 _ ); they typically react with water  to form bases or with acids to form salts. Oxides of nonmetallic elements  are volatile compounds in which a covalent bond joins the oxygen and the  nonmetal; they react with water to form acids or with bases to form salts.  A few substances (e.g., aluminum, zinc) form amphoteric oxides, which  form salts with both acids and bases. Certain organic compounds form  oxides in which the oxygen is covalently bonded to an atom of nitrogen  (amine oxides), phosphorus (phosphine oxides), or sulfur (sulfoxides) in  the organic molecule.</p><p>oxide mineral Any naturally occurring inorganic compound with a  structure based on close-packed oxygen atoms in which smaller, posi�  tively charged metal or other ions occur. Oxide minerals are common in  all rock types, whether igneous, sedimentary, or metamorphic.</p><p>Oxus River See Amu Darya</p><p>oxygen Gaseous chemical element, chemical symbol O, atomic number  8. It constitutes 21% (by volume) of air and more than 46% (by weight)  of Earth�s crust, where it is the most plentiful element. It is a colourless,  odourless, tasteless gas, occurring as the diatomic molecule 0 2 . In respi�  ration, it is taken up by animals and some bacteria (and by plants in the  dark), which give off carbon dioxide (C0 2 ). In photosynthesis, green plants  assimilate carbon dioxide in the presence of sunlight and give off oxygen.  The small amount of oxygen that dissolves in water is essential for the  respiration of fish and other aquatic life. Oxygen takes part in combus�  tion and in corrosion but does not itself burn. It has valence 2 in com�  pounds; the most important is water. It forms oxides and is part of many  other molecules and functional groups, including nitrate, sulfate, phosphate,  and carbonate; alcohols, aldehydes, carboxylic acids, and ketones; and per�  oxides. Obtained for industrial use by distillation of liquefied air, oxygen  is used in steelmaking and other metallurgical processes and in the chemi�  cal industry. Medical uses include respiratory therapy, incubators, and  inhaled anesthetics. Oxygen is part of all gas mixtures for manned space�  craft, scuba divers, workers in closed environments, and hyperbaric cham�  bers. It is also used in rocket engines as an oxidizer (in liquefied form)  and in water and waste treatment processes.</p><p>oxygen process, basic See basic oxygen process</p><p>Oxyrhynchus \,ak-si-Tiq-k3s\ Archaeological site, Egypt, on the west�  ern bank of the Nile River.

The  papyri, written mainly in Greek and Latin, contain both religious texts  and masterpieces of Greek classical literature. Some of these texts, once  considered lost, were by Pindar and Callimachus. The modem village of  Al-Bahnasa is located on the site.</p><p>Oyo empire Yoruba state in present-day southwestern Nigeria that  dominated the land between the Volta and Niger rivers in 1650-1750. Two  waves of immigrants probably entered the area c. ad 700-1000, and the  second wave formed a state at Oyo. This state became preeminent among  Yoruba states because of its good trading position, natural resources, and  industrious inhabitants. Though at first less powerful than its neighbours,  by the end of the 16th century its ruler, Orompoto, had used trade-derived  wealth to maintain a trained army. In the 18th century Oyo subjugated the  Dahomey kingdom and had begun  trading with European merchants at  Dahomey�s ports. Oyo�s wealth  increased, but Abiodun (r. c. 1770-  90) neglected the army and the pos�  sibilities for territorial expansion,  thus weakening central authority for  his successor. Soon after 1800 Oyo  was captured by Fuiani Muslims  from Hausaland.

After studying electrical engineering, he oversaw Turkey�s electrifi�  cation program in the 1950s and �60s. After working as a World Bank  economist for most of the 1970s, he was elected prime minister as head  of his own Motherland Party in 1983 and was reelected in 1987. In 1989  he persuaded the parliament to make him president, a traditionally non�  political position, and used the office to claim for Turkey an important  role in the Persian Gulf War (1990-91).</p><p>Ozark Mountains or Ozark Plateau Heavily forested highlands,  south-central U.S. Extending southwest from St. Louis to the Arkansas  River, they occupy an area of about 50,000 sq mi (130,000 sq km) in Mis�  souri, Arkansas, Illinois, and Kansas. Many of the highest peaks exceed  2,000 ft (600 m). Tourism is one of the region�s chief industries. Lake of  the Ozarks provides power and recreational facilities. The name Ozark  probably derives from the French trading post, Aux Arc, established in  the area in the 1700s.</p><p>Ozarks, Lake of the Lake, south-central Missouri, U.S. One of the  largest man-made lakes in the U.S., it is located in the scenic Ozark Moun�  tains.

Like  ordinary oxygen gas (0 2 ), it contains oxygen atoms, but the bonding of  three atoms per molecule gives it distinctive properties. It is formed in  electrical discharges and accounts for the distinctive odour of the air after  thunderstorms or near electrical equipment. Usually manufactured on the  spot by passing an electric discharge through oxygen or air, it is used in  water purification, deodorization, bleaching, and various chemical reac�  tions that require a strong oxidizing agent (see oxidation-reduction). Small  amounts that occur naturally in the stratospheric ozone layer absorb ultra�  violet (UV) radiation that otherwise could severely damage living organ�  isms. Near Earth�s surface, ozone contributes to air pollution, ozone  produced by auto emissions in the presence of sunlight being a deleteri�  ous component of smog, and also accelerates the deterioration of rubber.</p><p>ozone layer or ozonosphere Region in the upper atmosphere, about  6-30 mi (10-50 km) high, with significant concentrations of ozone,  formed by the effect of solar ultraviolet (UV) radiation on oxygen and also  present in trace quantities elsewhere in earth�s atmosphere. Ozone  strongly absorbs solar UV radiation, causing atmospheric temperature to  climb to about 30�F (0�C) at the top of the layer, and preventing much  of this radiation from reaching earth�s surface, where it would injure many</p><p>living things. Chlorofluorocarbons, or CFCs, and some other air pollut�  ants that diffuse into the ozone layer destroy ozone. In the mid-1980s,  scientists discovered that a �hole��an area where the ozone is up to 50%  thinner than normal�develops periodically in the ozone layer above Ant�  arctica. This severe regional depletion, explained as a natural seasonal  depletion, appears to have been exacerbated by the effects of CFCs, and  may have led to an increase in skin cancer caused by UV exposure.  Restrictions on the manufacture and use of CFCs and other ozone-  destroying pollutants were imposed in 1978.</p><p>Ozu \'o-zu\ Yasujiro (b. Dec. 15, 1903, Tokyo, Japan�d.

National  boundaries in the region were not definitively established prior to the  conflict, and in the 1870s Chile controlled nitrate fields claimed by Peru  and Bolivia. When demand for nitrates rose, war broke out over the ter�  ritory. Chile defeated both countries and took control of valuable mining  areas in each; Bolivia lost its entire Pacific coast. A 1904 treaty gave  Bolivia freedom of transit through Chilean territory, but Bolivia contin�  ued to try to escape its landlocked status (see Chaco War). Peru foun�  dered economically for decades after the war. A final accord between Peru  and Chile was reached only in 1929 through U.S. mediation.</p><p>Pacific Coast Ranges See Coast Ranges</p><p>Pacific Islands, Trust Territory of the Former United Nations trust�  eeship, administered by the U.S. from 1947 to 1986.

The first genuinely pacifist move�  ment was Buddhism, whose founder demanded from his followers absolute  abstention from any act of violence against their fellow creatures. The  ancient Greek conception of pacifism applied to individual conduct rather  than to the actions of peoples or kingdoms. The Romans conceived of  pax, or peace, as a covenant between states or kingdoms that creates a  �just� situation based on mutual recognition. This judicial approach was  applicable only to the �civilized world,� however. Though the spoken  words of Jesus as recorded in the New Testament could be interpreted as  a kind of pacifism (and in fact were so interpreted by many of his early  followers), from the early 3rd century through the Middle Ages the Chris�  tian church itself held that armies were necessary to combat nonbeliev�  ers or demons. In the 17th and 18th centuries, much pacifist thinking was  based on the idea that transferring power from sovereigns to the people  would result in peace, because, it was claimed, wars were a product of  sovereigns� ambitions and pride. In the 19th and 20th centuries, pacifism  inspired widespread interest in general disarmament and in the creation  of international organizations for the peaceful resolution of disputes, such  as the League of Nations and the United Nations. Pacifism as a national  policy, rather than as a standard of individual conduct, has yet to satis�  factorily address the problem of an aggressor that does not possess simi�  lar moral scruples. Individual pacifism may lead one to become a  conscientious objector. Historically important pacifists include Leo Tolstoy,  Mohandas K. Gandhi, and Martin Luther King, Jr.</p><p>Pacino Xps-'che-noV Al(fredo James) (b. April 25, 1940, New York,  N.Y., U.S.) U.S. actor.

Legend holds that it  was founded by the Trojan hero Antenor. First mentioned in 302 bc, it</p><p>prospered as a Roman city and was under Lombard rule in the 7th-8th  centuries. A leading Italian commune in the 11th�13th centuries, control  of Padua then passed to Venice from 1405 to 1797. Under Austrian rule  (1815-66) the city was active in the Risorgimento (movement for Italian  independence). Padua was heavily bombed in World War II but was  rebuilt. Its historic buildings contain works by many artists, including  Giotto, Titian, Donatello, and Mantegna. The University of Padua (1222),  the second oldest in Italy (after Bologna), had Galileo among its teachers  and Dante, Petrarch, and Tasso among its students. Padua�s botanical gar�  den (1545) is the oldest in Europe. The city is now a commercial and  industrial centre.</p><p>Paekche \'pak-,ch3\ One of three kingdoms into which Korea was  divided before ad 660.

In the 3rd century ad Paekche emerged  as a fully developed kingdom, and by the 4th century it had extended its  territory from the southwestern tip of the Korean peninsula to the whole  Han River basin in central Korea. By then it was a centralized aristocratic  state. Confucianism and Buddhism flourished, and Paekche�s visual arts  revealed technical maturity and warm human qualities. In the 5th century  it was pushed back south by the northern Korean kingdom of Koguryo,  and in 660 it fell to an alliance of the southern Korean state of Silla and  the Tang-dynasty China.</p><p>Paeonia \pe-'o-ne-o\ Ancient land, in what is now northern Greece, the  Republic of Macedonia, and western Bulgaria. Paeonia originally  included the whole Vardar River valley. The Paeonians were weakened  by the Persian invasion of 490 bc, and the tribes living along the Stry-  mon River fell under Thracian control. The growth of ancient Macedonia  forced the remaining tribes north, and they were defeated by Philip II in  358 bc. It became part of the Roman province of Macedonia; by ad 400  the Paeonians had lost their identity and Paeonia was merely a geographic  term.</p><p>Paestum Vpes-tom, 'pes-tomX Ancient city, southern Italy.

After an edu�  cation in Switzerland, he replaced his father, Reza Shah Pahlavi, as ruler  when the latter was forced into exile by the British. His rule was marked  by a power struggle with his premier, Mohammad Mosaddeq, who briefly  succeeded in deposing him in 1953; covert intervention by British and  U.S. intelligence services returned him to the throne the next year. His  program of rapid modernization and oil-field development initially  brought him popular support, but his autocratic style and suppression of  dissent, along with corruption and the unequal distribution of Iran�s new  oil wealth, increased opposition led by exiled cleric Ayatollah Ruhollah  Khomeini. In 1979 Pahlavi was forced into exile.</p><p>Pahlavi, Reza Shah (b. March 16, 1878, Alasht, Qajar Iran�d. July  26, 1944, Johannesburg, S.Af.) Shah of Iran (1926�41).

He sought to bring order and end Iran�s political chaos and its  domination by Britain and Soviet Russia following World War I (1914�  18). He constructed roads, schools, and hospitals, opened a university, and  built the Trans-Iranian Railway. He emancipated women, nationalized  several economic sectors, and reduced the clergy�s power. He often used  repressive methods, which eventually cost him his popularity. During  World War II (1939�45), fearing that Pahlavi might side with Germany,  the U.S. and Britain occupied Iran.

Pain,  in its simplest form, is a warning mechanism that helps protect an organ�  ism by influencing it to withdraw from harmful stimuli (such as a pin�  prick). In its more complex form, such as in the case of a chronic condition  accompanied by depression or anxiety, it can be difficult to isolate and  treat. Pain receptors, found in the skin and other tissues, are nerve fibres  that react to mechanical, thermal, and chemical stimuli. Pain impulses  enter the spinal cord and are transmitted to the brain stem and thalamus.  The perception of pain is highly variable among individuals; it is influ�  enced by previous experiences, cultural attitudes (including gender ste�  reotypes), and genetic makeup. Medication, rest, and emotional support  are the standard treatments. The most potent pain-relieving drugs are opium  and morphine, followed by less-addictive substances and non-narcotic  ANALGESICS Such as ASPIRIN and IBUPROFEN.</p><p>Paine, Robert Treat (b.

After a series of professional failures in England, he met Benjamin  Franklin, who advised him to immigrate to America. He arrived in Phila�  delphia in 1774 and helped edit the Pennsylvania Magazine. In January  1776 he wrote Common Sense, a 50-page pamphlet eloquently advocat�</p><p>ing independence; more than  500,000 copies were quickly sold,  and it greatly strengthened the colo�  nists� resolve. As a volunteer aide to  Gen. Nathanael Greene during the  American Revolution he wrote his 16  �Crisis� papers (1776-83), each  signed �Common Sense�; the first,  beginning �These are the times that  try men�s souls,� was read to the  troops at Valley Forge on George  Washington�s order. In 1787 Paine  traveled to England and became  involved in debate over the French  Revolution; his The Rights of Man  (1791-92) defended the revolution  and espoused republicanism. Viewed  as an attack on the monarchy, it was  banned, and Paine was declared an  outlaw in England. He then went to  France, where he was elected to the  National Convention (1792-93).</p><p>After he criticized the Reign of Ter�  ror, he was imprisoned by Maximiuen  Robespierre (1793-94).

Painting as an art form  dates back to prehistoric cave paintings. The early cultural traditions of  tribes, religions, guilds, royal courts, and states controlled the craft, form,  imagery, and subject matter of painting and determined its function (e.g.,  ritualistic, devotional, decorative). Painters were considered skilled arti�  sans rather than creative artists until eventually, in East Asia and Renais�  sance Europe, the fine artist emerged with the social status of a scholar  and courtier. Fine artists signed their work and decided its design and often  its subject and imagery. Over time painters have increasingly gained the  freedom to invent their own visual language and to experiment with new  forms and unconventional materials and techniques. In the early 20th  century painters began to experiment with nonrepresentational art in  which formal qualities such as line, colour, and form were explored rather  than subject matter. Throughout the century styles vacillated between  representational and nonrepresentational painting. In the late 20th century  some critics forecast the �death of painting� in the face of new media  such as video and intallation art, yet talented new artists repeatedly  brought painting back to the centre of artistic production.</p><p>pair production Formation of an electron and a positron from high-  energy electromagnetic radiation traveling through matter, usually in the  vicinity of an atomic nucleus. It is a direct conversion of radiant energy  into matter in accordance with the equation E = me 2 , where E is the  amount of energy, m is the mass, and c is the speed of light. It is one of  the principal ways in which high-energy gamma rays are absorbed in mat�  ter. The positrons quickly disappear by being reconverted into photons in  the process of annihilation with other electrons. Pair production may  sometimes refer to the formation of other particle/antiparticle pairs as  well.</p><p>Paisiello X.pa-ez-'ye-loV, Giovanni (b. May 9, 1740, Taranto, King�  dom of Naples�d.

He had his first  operatic success in Vienna in 1784 then returned to Naples to become  dramatic composer to Ferdinand IV. In 1802 Paisiello was invited by  Napoleon to work in Paris, but after two years he returned to Naples,  where, despite changes in regime, he retained his court post until 1815.  He composed more than 80 operas, including a very popular Barber of  Seville (1782).</p><p>Paisley, Ian (Richard Kyle) (b. April 6, 1926, Armagh, County  Armagh, N.Ire.) Protestant leader in Northern Ireland. After being ordained  in the Reformed Presbyterian church (1946), he cofounded a new sect, the  Free Presbyterian Church of Ulster (1951), which soon grew to more than  30 churches. In the 1960s he became the voice of extreme Protestant opin�  ion in the sectarian strife of Northern Ireland, opposed to any concessions  to the Catholics. He led demonstrations throughout Northern Ireland and  was repeatedly imprisoned for unlawful assembly. Elected to the House of  Commons in 1970, he cofounded the Democratic Unionist Party in 1971  and also organized a paramilitary group of Protestant fighters called the  Third Force. In 1998 he opposed the Good Friday Agreement, which called  for power sharing between Roman Catholics and Protestants.

The  Northern Paiute occupied east-central California, western Nevada, and  eastern Oregon. Both groups were primarily food collectors who subsisted  on wild plant foods supplemented by small game. They occupied tempo�  rary brush shelters, used rabbit-skin clothing, and made baskets for food  gathering. They were organized in loosely knit bands.

Pakistan may be divided into four regions: the  northern mountains, the Balochistan Plateau, the Indus Plain, and the  desert areas. The Himalayan and Trans-Himalayan ranges form the great  mountain areas of the northernmost part of the country; some of the high�  est peaks are K2 and Nanga Parbat. The country has a developing mixed  economy based largely on agriculture, light industries, and services.  Remittances from Pakistanis working abroad are a major source of foreign  exchange. Pakistan is a military-backed constitutional regime with two  legislative houses; its chief of state is the president, assisted by the prime  minister. The area has been inhabited since the 3rd millennium bc. From  the 3rd century bc to the 2nd century ad, it was part of the Mauryan and  Kushan kingdoms. The first Muslim conquests were in the 8th century ad.  The British East India Co. subdued the reigning Mughal dynasty in 1757.  During the period of British colonial rule, what is now (Muslim) Pakistan  was part of (Hindu) India. The new state of Pakistan came into existence  in 1947 by act of the British Parliament. The Kashmir region remained a  disputed territory between Pakistan and India, with tensions resulting in  military clashes and full-scale war in 1965. Civil war between East and  West Pakistan in 1971 resulted in independence for Bangladesh (formerly  East Pakistan) in 1972.

The word derives from Rome�s Palatine Hill, where the  emperors built their residences. The earliest known palaces are those of  the Egyptian kings at Thebes, with an outer wall enclosing a labyrinth of  rooms and courtyards. Other ancient cultures also built vast palaces (e.g.,  the Assyrian palaces at Nimrud, Khorsabad, and Nineveh; the Minoan  palace at Knossos; and the Persian palaces at Persepolis and Susa). In  Rome and Constantinople, palaces reached their peak as centres of power.  In Western Europe after the Middle Ages, palaces tended to be single  buildings. In Renaissance Italy every prince had his royal palace, usually  with an internal court surrounded by an arcade. The court of the Pitti Pal�  ace in Florence (1560) is an important example of Mannerist architecture.  French palaces include the Louvre and Versailles; Spanish palaces include  El Escorial and the Alhambra. In contrast to the typical Western format,  East Asian palaces, such as the imperial palaces of Japan and those in  Beijing�s Forbidden City, consist of many buildings (in these cases, low  pavilions mostly of highly decorated wood construction) within vast  walled gardens.</p><p>Palacky \'pa-lats-ke\, Frantisek (b.

His History of Bohemia (5 vol.,  1836-67) made him the founder of modern Czech historiography. Sup�  porting the concept of a federal Austria composed of nationalities with  equal rights, he was chairman of the 1848 Prague Slavic congress to pro�  mote Pan-Slavism.

From 1332 he was the chief defender of the school of  mysticism known as Hesychasm, which integrated repetitive prayer with  bodily postures and controlled breathing. His Apology for the Holy Hesy-  chasts (1338) is a justification for mystical experience that involves both  soul and body; his Book of Holiness (1344) is the fundamental textbook  of Byzantine mysticism. He was made bishop of Thessalonica in 1347,  and in 1368 he was acclaimed a saint and named Father and Doctor of  the Orthodox church.</p><p>palate \'pa-lst\ Roof of the mouth, separating the oral and nasal cavi�  ties. The front two-thirds, the hard palate, is a plate of bone covered by  mucous membrane. It gives the tongue a surface against which to make  speech sounds and shape food during chewing and keeps pressures in the  mouth from closing off the nasal passage. The flexible soft palate behind  it is made of muscle and connective tissue and ends in the uvula, a fleshy  projection. It rises to block the nasal cavity (see nose) and upper pharynx  off from the mouth and lower pharynx for swallowing or to create a  vacuum for drinking. Cleft palate, a congenital disorder involving a gap  in the palate, can be corrected surgically.</p><p>Palatinate \p3-'la-t 3 n-3t\ German Pfalz \'pfalts\ Historical region,  now part of Germany. The region was once under the jurisdiction of the  counts palatine (secular princes), who in the 14th century became electors  of the Holy Roman Empire. In the 16th and 17th centuries the Palatinate  was a stronghold of Protestantism. It was divided into two parts: the  Lower, or Rhenish, Palatinate, on both sides of the Rhine River in the area  south of the Main River; and the Upper Palatinate, in northern Bavaria  around Amberg and Regensburg. The boundaries of the Palatinate varied  with the political and dynastic fortunes of the counts palatine.</p><p>Palau \p3-'lau\ officially Republic of Palau Island country, western  Pacific Ocean. Area: 188 sq mi (488 sq km). Population (2005 est.):  21,100. Capital: Koror (acting); scheduled to move to the island of  Babelthuap in 2006. The population is of mixed Malay, Melanesian, Fili�  pino, and Polynesian ancestry. Languages: Palauan, Sonsorolese-Tobian,  English (all official). Religion: Christianity (mostly Roman Catholic; also  Protestant, other Christians). Currency: U.S. dollar. The islands of the  Palau group are fertile, with mangrove swamps along the coasts, backed</p><p>by savanna and palms rising to rainforests in the hills. The major source  of employment is government service. Subsistence farming and fishing  are the main occupations in the rural areas. Palau is a republic with two  legislative houses; its head of state and government is the president. The  islands had been under nominal Spanish ownership when they were sold  to Germany in 1899. They were seized by Japan in 1914 and taken by  Allied forces in 1944 during World War II. Palau became part of the U.S.  Trust Territory of the Pacific Islands in 1947 and became a sovereign state  in 1994; the U.S. provides economic assistance and maintains a military  presence in the islands.</p><p>Palawan \pa-'la-wan\ Island (pop., 2000: 713,539), southwestern Phil�  ippines. It is long and narrow and extends northeast to southwest between  the South China Sea and the Sulu Sea. It has a mountainous backbone that  runs its entire length, with the highest peak at Mount Mantalingajan (6,839  ft [2,085 m]). The capital is Puerto Princesa. The similarity of Palawan�s  vegetation with that of Borneo is explained by remnants of a Pleistocene  Epoch land bridge that connected the two islands. A coastal plain sup�  ports most of the population and is the main agricultural area of Palawan.  Scattered settlement and shifting agriculture predominate, with rice as the  main food crop. Oil drilling off the northern coast began in 1992.</p><p>pale District separated from the surrounding country by defined bound�  aries or set apart by a distinctive administrative and legal system.

The  simplest kind of paleogeography is a map showing the locations of ancient  lands and seas, but paleogeographic maps may also show the occurrence  and distribution of fossil, plant, and animal communities; environments  of sedimentation (e.g., deltas, reefs, deserts, or deep-sea basins); areas  undergoing uplift and erosion or subsidence and deposition; and major  climatic zones.</p><p>paleogeology or palaeogeology Geology of a region at any given  time in the distant past. Paleogeologic reconstructions in map form show  not only the ancient topography of a region but also the distribution of  rocks beneath the surface and such structural features as faults and folds.  Maps of this kind help investigators determine deformation events in a  region, stream-drainage patterns now buried under layers of sediment, and  the extent of ancient oceans and seas. They also provide a useful tool for  petroleum geologists, enabling them to identify geologic structures where  oil or natural gas may be trapped.</p><p>paleohydrology or palaeohydrology Scientific discipline con�  cerned with hydrologic systems as they existed during previous periods  of Earth history.

During the Lower Paleolithic (c. 2,500,000-200,000  years ago), simple pebble tools and crude stone choppers were made by  the earliest humans. About 700,000 years ago, the first rough hand ax  appeared; it was later refined and used with other tools in the Acheulean  industry. A flake-tool tradition emerged in the Middle Paleolithic, as exem�  plified by implements of the Mousterian industry. The Upper Paleolithic  (40,000-10,000 bc) saw the emergence of more complex, specialized, and  diverse regional stone-tool industries, such as the Aurignacian, Solutrean,  and Magdalenian. The two principal forms of Paleolithic art are small  sculptures�such as the so-called Venus figurines and various carved or  shaped animal and other figures�and monumental paintings, incised  designs, and reliefs on the walls of caves such as Altamira (in Spain) and  Lascaux Grotto (in France). The end of the Paleolithic is marked by the  emergence of the settled agricultural villages of the Neolithic Period.</p><p>paleomagnetism or palaeomagnetism or remanent mag�  netism Permanent magnetism in rocks, resulting from the orientation of  the Earth�s magnetic field at the time of rock formation in a past geologic  age. It is a source of information for the paleomagnetic studies of polar  WANDERING and PLATE TECTONICS.</p><p>paleontology or palaeontology Scientific study of life of the geo�  logic past, involving analysis of plant and animal fossils preserved in rocks.  It is concerned with all aspects of the biology of ancient life forms: their  shape and structure, evolutionary patterns, taxonomic relationships with  each other and with modern species, geographic distribution, and interre�  lationships with the environment. Paleontology has played a key role in  reconstructing the Earth�s history and has provided evidence to support the  theory of evolution. Data from paleontologic studies have also aided petro�  leum geologists in locating deposits of oil and natural gas, which are fre�  quently associated with the remains of certain ancient life forms.</p><p>Paleozoic V.pa-le-o-'zo-ikV Era or Palaeozoic Era Major interval of  geologic time, c. 543-248 million years ago. From the Greek for �ancient  life,� it is the first era of the Phanerozoic Eon and is followed by the  Mesozoic Era. It is divided into six periods: (from oldest to youngest) the  Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. Dur�  ing the early Paleozoic, much of North America was covered by a warm,  shallow sea with many coral reefs. Fossils from this time include marine</p><p>invertebrates and primitive fish; the plants were predominantly algae, with  some mosses and ferns. During the late Paleozoic, huge, swampy forest  regions covered much of the northern continents. Plant and animal life  flourished. Amphibians left the oceans to live on land, reptiles evolved as  fully terrestrial life forms, and insect life began. Ferns grew to tree size,  and precursors of the conifers appeared.</p><p>Palermo ancient Panormus City (pop., 2001: 686,722), seaport, and  capital of Sicily. Located on the Bay of Palermo, the city was founded by  Phoenician traders in the 8th century bc; it was later a Carthaginian settle�  ment. It was taken by the Romans in 254 bc. Conquered by the Arab troops  of the Aghlabid dynasty in 831, it flourished as a centre of trade with North  Africa. Palermo was thus quite prosperous when it fell to the Norman  adventurers Roger I and Robert Guiscard in 1072. The ensuing era of Nor�  man rule (1072-1194) was Palermo�s golden age, particularly after the  founding of the Norman kingdom of Sicily in 1130 by Roger II. In 1194  Germany�s Hohenstaufen ruler, Frederick II, took over. Palermo was con�  quered by the French under Charles of Anjou in 1266, but Angevin oppres�  sion was ended in 1282 by a popular uprising called the Sicilian Vespers.  After 1412 the crown of Sicily was united with that of Aragon and sub�  sequently with that of Spain. Palermo declined during this long period of  Spanish rule. The city was taken by Italian patriot Giuseppe de Garibaldi  in 1860 and made part of the kingdom of Italy. Heavily bombed during  World War II, it was captured by Allied forces in 1943. Notable build�  ings from the Norman and later periods include the cathedral that con�  tains the tombs of Roger II and Frederick II. Palermo is Sicily�s chief  port, and ship repair is an important industry.</p><p>Palestine biblical Canaan Region, at the eastern end of the Mediter�  ranean Sea. It extends east to the Jordan River, north to the border between  Israel and Lebanon, west to the Mediterranean, and south to the Negev  desert, reaching the Gulf of Aqaba. The political status and geographic area  designated by the term have changed considerably over the course of three  millennia. The eastern boundary has been particularly fluid, often under�  stood as lying east of the Jordan and extending at times to the edge of the  Arabian Desert. A land of sharp contrasts, Palestine includes the Dead Sea,  the lowest natural point of elevation on Earth, and mountain peaks higher  than 2,000 ft (610 m) above sea level. In the 20th and 21st centuries it has  been the object of conflicting claims by Jewish and Arab national move�  ments. The region is sacred to Judaism, Christianity, and Islam. Settled  since early prehistoric times, mainly by Semitic groups, it was occupied in  biblical times by the kingdoms of Israel, Judah, and Judaea. It was subse�  quently held by virtually every power of the Middle East, including the  Assyrians, Persians, Romans, Byzantines, Crusaders, and Ottomans. It was  governed by Britain under a League of Nations mandate from the end of  World War I (1914-18) until 1948, when the State of Israel was proclaimed.  Armies from Egypt, Transjordan, Syria, and Iraq attacked the next day.  They were defeated by the Israeli army.

It was formed in 1964 to centralize the leadership of various  groups. After the Six-Day War of 1967, the PLO promoted a distinctively  Palestinian agenda. In 1969 Yasir �Arafat, leader of Fatah, the PLO�s larg�  est faction, became its chairman. From the late 1960s the PLO engaged  in guerrilla attacks on Israel from bases in Jordan, from which it was  expelled in 1971. PLO headquarters moved to Lebanon. In 1974 'Arafat  advocated limiting PLO activity to direct attacks against Israel, and the  Arab community recognized the PLO as the sole legitimate representa�  tive of all Palestinians. It was admitted to the Arab League in 1976. In  1982 Israel invaded Lebanon and expelled PLO forces based there. In  1988 the PLO leadership, then based in Tunis, declared a Palestinian state  and the following year elected 'Arafat its president. It also recognized  Israel�s right to exist, though several militant factions dissented. In 1993  Israel recognized the PLO by signing an agreement with it granting Pal�  estinian self-rule in parts of the West Bank and Gaza Strip.

Nearby is the coastal city of Kolonia (pop., 2000:  5,681), the island�s other large town.</p><p>Palissy\pa-le-'se\, Bernard (b. 1509, St. Avit, France�d. 1590, Paris)  French potter and writer. Known for his decorated rustic ware, a type of  earthenware covered with coloured lead glazes, he was appointed �inven�  tor of rustic pottery to the king and the queen mother� in 1565. His pub�  lic lectures on natural history, published in 1580, revealed him to be a  writer and scientist and a pioneer of the scientific method. A Huguenot,  he was imprisoned in 1588 in the Bastille, where he died.</p><p>Palladio \pa-'lad-yo\, Andrea orig. Andrea di Pietro della  Gondola (b. Nov. 30, 1508, Padua, Republic of Venice�d. August  1580, Vicenza) Italian architect. While a young mason, he was noticed by  an Italian scholar and soon found himself studying mathematics, music,  philosophy, and Classical authors. From 1541 he made several trips to  Rome to study ancient ruins. His first palace design, the Palazzo Civena  (1540^46), was innovative for its use of an arcaded area behind the main</p><p>elevation, in imitation of a Roman forum. In his villas, Palladio tried to  re-create the Roman villa based on ancient descriptions. His first, Villa  Godi at Lonedo (c. 1540^-2), contained elements for which he is famous,  including symmetrical wings and a walled court. His most widely copied  villa was the Villa Rotonda (1550-51), near Vicenza. Palladio was the  first to systematize the plan of a house and to use the ancient Greco-  Roman temple front as a portico. His reconstruction of the Basilica (town  hall) in Vicenza (begun 1549) employs a two-story arcade with a motif  that came to be known as Palladian: rounded arches flanked by rectan�  gular openings. His facades for San Francesco della Vigna (c. 1565), San  Giorgio Maggiore (begun 1566), and II Redentore (begun 1576), all in  Venice, became prototypes for attaching Classical temple fronts to basil�  ican churches. Though Palladio absorbed contemporary Mannerist motifs,  his plans and elevations always retained a repose and order not associ�  ated with Mannerist architecture. His Four Books of Architecture was  possibly the most influential architectural pattern book ever printed. His  influence climaxed during the 18th-century Classical Revival; the result�  ing Palladianism spread through Europe and the U.S.</p><p>palladium Metallic chemical element, one of the transition elements,  chemical symbol Pd, atomic number 46. A precious, silver-white metal  that resembles platinum chemically, it is extremely ductile and easily  worked and can be beaten into thin leaf. It is an excellent catalyst for  chemical reactions involving hydrogen and oxygen, such as the hydroge�  nation of unsaturated organic compounds. Because it does not tarnish in  air at ordinary temperatures, palladium and its alloys serve as substitutes  for platinum in jewelry and in electrical contacts in telecommunications  equipment. Small amounts of palladium alloyed with gold yield the best  white gold. Palladium is used also in dental alloys. Because hydrogen  passes rapidly through the metal at high temperatures, heated palladium  tubes impervious to other gases function as semipermeable membranes  and are used for hydrogen purification.</p><p>palm Any of about 2,800 species of flowering, subtropical trees, shrubs,  and vines that make up the family  Arecaceae (or Palmae). Many are  economically important. Palms fur�  nish food, shelter, clothing, timber,  fuel, building materials, fibres,  starch, oils, waxes, and wines for  local populations in the tropics.</p><p>Many species have very limited  ranges; some grow only on single  islands. The fast growth and many  by-products of palms make exploita�  tion of the rainforest appealing to  agribusiness. The usually tall,  unbranched, columnar trunk is  crowned by a tuft of large, pleated,  fan- or feather-shaped leaves, with  often prickly petioles (leafstalks), the  bases of which remain after leaves  drop, often covering the trunk. Trunk  height and diameter, leaf length, and  seed size vary greatly. Small flowers  are produced in large clusters.</p><p>Among the most important palms are  the sugar palm ( Arenga pinnata, or A. saccharifera), coconut palm, date  palm, and cabbage palmetto.</p><p>palm PC Computer small enough to fit in a person�s palm. Palm PCs  (also called palmtops, handheld computers, or personal data assistants)  typically use pens instead of keyboards for data input. They have limited  memory and lack built-in peripheral devices (e.g., disk drives and  modems), though such devices can be plugged in through peripheral slots.  They run a limited set of application programs, such as calendars, address  books, and memo pads.</p><p>Palm Springs Resort city (pop., 2000: 42,807), southern California,  U.S. It is located in the Coachella Valley. Originally known as Agua Cal-  iente for its hot springs, it was a stagecoach stop by 1872. In 1884 John  G. McCallum established the Palm Valley Colony there.

It usually includes a procession of members of  the congregation carrying palms, representing the palm branches the  crowd scattered in front of Jesus as he rode into the city. The liturgy also  includes readings recounting the suffering and death of Jesus. Palm Sun�  day was celebrated in Jerusalem as early as the 4th century and in the  West by the 8th century.</p><p>Palma (de Mallorca) City (pop., 2001: 333,801), capital of the Bale�  aric Islands and of Majorca island, Spain. Palma lies on the southwestern  coast of Majorca on Palma Bay in the western Mediterranean Sea.  Romans conquered Majorca in 123 bc, and it was later ruled by Byzan�  tines and Arabs before being taken by James I of Aragon in 1229. The  city�s old sections have many notable homes built in the 16th and 18th  centuries. Historic buildings include the Gothic cathedral and Bellver  Castle.

After studying in Sweden and the U.S., he was  elected to the Swedish parliament (1958) and became a leader of the  Swedish Social Democratic Workers� Party. He served in ministerial posts  from 1963 and became prime minister in 1969. A strong pacifist, he  attacked U.S. policy in the Vietnam War and later acted as a UN special  envoy to mediate in the Iran-Iraq War. After his reelection in 1982, he  tried to reinstate socialist economic policies in Sweden. He was shot to  death by an assassin in 1986; his murder remains unsolved.</p><p>Palmer, A(lexander) Mitchell (b. May 4, 1872, Moosehead, Pa.,  U.S.�d. May 11, 1936, Washington, D.C.) U.S. politician. He served in  the U.S. House of Representatives from 1909 to 1915 and helped secure  the Democratic Party presidential nomination for Woodrow Wilson in  1912. Appointed U.S. attorney general (1919-21), Palmer used the espio�  nage and sedition acts (1917, 1918) to attack political radicals, dissidents,  and aliens in the �Red Scare� period following World War I. The  government-led roundup of suspected communists became known as the  �Palmer raids.� In 1920 he ran unsuccessfully for the presidential nomi�  nation of the Democratic Party.</p><p>Palmer, Arnold (Daniel) (b. Sept. 10, 1929, Latrobe, Pa., U.S.) U.S.  golfer. The son of a greenskeeper,</p><p>Palmer turned professional in 1954  after winning the U.S. Amateur  championship. He was the first  player to win the Masters Tournament  four times (1958, 1960, 1962, 1964);  his other major titles include the U.S.</p><p>Open (1960) and the British Open  (1961-62). From 1954 through 1975  he won 61 tournaments. He won the  PGA Senior Open in 1980 and 1981.</p><p>He was the first golfer to earn  $1,000,000 in tournament prize  money. His exciting play and ami�  able personality won him wide popu�  larity among fans, who became  known as �Amie�s Army.� Palmer  was also the first athlete to parlay  success on the playing field into  lucrative off-the-field contracts, and  thus he paved the way for athletes  who followed to earn substantial  sums from endorsement contracts.</p><p>Palmer, Samuel (b. Jan. 27,</p><p>1805, London, Eng.�d. May 24,</p><p>1881, Redhill, Surrey) British  painter and etcher. He began exhibiting conventional landscapes at the  Royal Academy by 14. After converting to a personal form of High Angli�  canism and discovering medieval art, he developed a visionary style, dis�  playing a mystical but precise depiction of nature and an overflowing</p><p>religious intensity, united by a vivid re-creation of the pastoral conven�  tions. In these works he was encouraged and influenced by William Blake.  As his religious fervour faded after 1830, the precarious balance between  realism and vision was lost.</p><p>Palmerston (of Palmerston), Henry John Temple, 3rd Vis�  count known as Lord Palmerston (b.

He entered Parliament  in 1807 as a Tory and served as secretary at war (1809-28). Associated  with the Whig Party from 1830, he served many years as foreign secre�  tary (1830-34, 1835^11, 1846-51) and supported British interests and  liberal causes abroad. He played a key role in establishing the indepen�  dence of Belgium (1830-31) and Greece (1832) and secured Turkey�s  integrity against France (1840). Appointed prime minister in 1855, he  brought an end to the Crimean War, approved the creation of the inde�  pendent Kingdom of Italy, and supported a policy of neutrality in the  American Civil War. Nicknamed �Pam,� he was a symbol of British  nationalism and one of Britain�s most popular leaders.</p><p>palmetto \pal-'me-to\ or cabbage palmetto Tree ( Sabalpalmetto)  of the palm family, occurring in the southeastern U.S. and the West Indies.  Commonly grown for shade and as ornamentals along avenues, palmet�  tos grow to about 80 ft (24 m) tall and have fan-shaped leaves. The water-  resistant trunk is used as wharf piling. Mats and baskets are sometimes  made from the leaves, and stiff brushes are made from the stems. The  buds are edible. S. texana, a similar species, occurs in the southwestern  U.S. and in Mexico.</p><p>palmistry Reading of an individual�s character and divination of the  future by interpreting lines on the palm of the hand. Palmistry may have  originated in ancient India, and it was probably from their original Indian  home that the traditional fortune-telling of the Gypsies was derived. It was  also practiced in China, Tibet, Persia, Mesopotamia, Egypt, and ancient  Greece. In medieval Europe it was used to discover witches, who were  thought to have pigmentation spots as signs of a pact with the devil.  Though palmistry is still practiced, there is no known scientific basis for  it.</p><p>Palmyra \pal-'ml-r3\ biblical Tadmor Ancient city, Syria, northeast  of Damascus, at the modem city of  Tadmur. Said to have been built by  King Solomon, it became prominent  in the 3rd century bc, when the Seleu-  cid dynasty made the road through  Palmyra one of the routes of east-  west trade. Under Roman control by  the reign of Tiberius, it briefly  regained autonomy in the 3rd cen�  tury ad under the Arab queen Zeno-  bia. The main military station on the  road that linked Damascus to the  Euphrates River, it was conquered by  the Muslims in 634.

The Argentine Pampas covers 295,000 sq mi (764,000 sq km) and  slopes gradually downward from northwest to southeast. The western  portion is dry and largely barren; the humid eastern portion is the nation�s  economic heart. Herds of wild cattle and horses, introduced by the Span�  iards and rounded up by Argentina�s famed gauchos, roamed the Pampas  until the later 19th century, when the land was fenced into huge estan-  cias (ranches). The region is prominent in Argentina�s gaucho literature  and musical folklore.</p><p>pamphlet Unbound printed publication with a paper cover or no cover.  Among the first printed materials, pamphlets were widely used in  England, France, and Germany from the early 16th century, often for reli�  gious or political propaganda; they sometimes rose to the level of litera�  ture or philosophical discourse. In North America, pre-Revolutionary War  agitation stimulated extensive pamphleteering; foremost among the writ�  ers of political pamphlets was Thomas Paine. By the 20th century, the  pamphlet was more often used for information than for controversy.</p><p>Pamplona Basque Iruna ancient Pompaelo City (pop., 2001:  183,964), capital of Navarra, northern Spain. According to tradition, it  was founded in 75 bc by Pompey the Great as a military settlement. It was  left almost derelict after Moorish and Frankish invasions in the 5th cen�  tury ad. It was captured from the Moors by Charlemagne in 778 and  became the capital of the kingdom of Navarra under Sancho III. In 1512  the armies of King Ferdinand of Aragon-Castile entered Pamplona, and  the portion of Navarra south of the Pyrenees was incorporated into Spain.  The citadel built by King Philip II of Spain in 1571 made it the most strongly  fortified town of the north. In 1841 it became the capital of the new  Navarra province. The chief tourist attraction is the Fiesta de San Fermfn  (honouring its first bishop), which is celebrated with bullfights and the  running of the bulls through the city streets. The fiesta is described in  Ernest Hemingway�s The Sun Also Rises.</p><p>Pan Greek fertility deity with a half-human, half-animal form. The  Romans associated him with Faunus. Pan was usually said to be the son  of Hermes. He was often represented as a vigorous and lustful figure with  the horns, legs, and ears of a goat; in later art his human parts were more  emphasized. Some Christian depictions of the Devil bear a striking resem�  blance to Pan. Pan haunted the high hills, where he was chiefly concerned  with flocks and herds. Like a shepherd, Pan was a piper, and he rested at  noon. He could inspire irrational terror in humans, and the word panic  comes from his name.</p><p>pan See playa</p><p>Pan-African movement Movement dedicated to establishing inde�  pendence for African nations and cultivating unity among black people  throughout the world. It originated in conferences held in London (1900,  1919, 1921, 1923) and other cities. W.E.B. Du Bois was a principal early  leader. The important sixth Pan-African conference (Manchester, 1945)  included Jomo Kenyatta and Kwame Nkrumah. The first truly intergovern�  mental conference was held in Accra, Ghana, in 1958, where Patrice  Lumumba was a key speaker. The Pan-Africanist Congress (PAC) was  founded by Robert M. Sobukwe and others in South Africa in 1959 as a  political alternative to the African National Congress, which was seen as  contaminated by non-African influences. The founding of the Organiza�  tion of African Unity (OAU; now the African Union) by Julius Nyerere and  others in 1963 was a milestone, and the OAU soon became the most  important Pan-Africanist organization.</p><p>Pan American (Sports) Games Quadrennial sports festival. The  games, conceived in 1940 as an event for the nations of the Western  Hemisphere, were first held in 1951. Patterned after the Olympic Games</p><p>and sanctioned by the International Olympic Committee, the games are  conducted by the Pan American Sports Organization (PASO), or Orga�  nization Deportiva Panamericana (ODEPA), headquartered in Mexico  City. All major international sports and several more specialized events  are included in the regular program. They are held the year preceding the  Olympics, in various host cities.</p><p>Pan-American Highway International highway system connecting  North and South America. Conceived in 1923 as a single route, the road  grew to include a number of designated highways in participating coun�  tries, including the Inter-American Highway from Nuevo Laredo, Mex.,  to Panama City, Pan. The whole system, extending from Alaska and  Canada to Chile, Argentina, and Brazil, totals nearly 30,000 mi (48,000  km). Only some 240 miles (400 km) in the Panama-Colombia border area  remain uncompleted.</p><p>Pan-American Union Organization formed in 1890 to promote coop�  eration among the countries of Latin America and the U.S. It was estab�  lished (as the International Union of American Republics) at the first Pan-  American conference, which was called by U.S. secretary of state James  Blaine in order to reach agreements on various common commercial and  juridical problems among the countries of the Americas. In 1948 it was  reconstituted as the Organization of American States.</p><p>Pan American World Airways, Inc. known as Pan Am Former  U.S. airline. It was founded in 1927 by former World War I pilot Juan  Trippe, who secured a contract to fly mail between Key West, Fla., and  Havana. In 1929 Pan Am established passenger service to the Caribbean  and Central America. It inaugurated the first transpacific flights (San Fran�  cisco to Manila) in 1936, the first transatlantic flights (New York City to  Lisbon) in 1939, and the first round-the-world flights in 1947, and it pio�  neered commercial jet travel in the 1950s. Its business declined in the  1960s and �70s, and its acquisition of National Airlines in 1980 failed to  improve its position. In 1988 a bomb planted aboard a Pan Am 747 caused  the airliner to crash near Lockerbie, Scot., killing 270 people. Despite  selling its Asian and South Pacific routes to United Airlines and its trans�  atlantic, European, and Middle Eastern routes to Delta Air Lines, it was  forced to declare bankruptcy in 1991. In the late 1990s another group  bought the rights to the Pan Am name and began operating flights as Pan  American Airways.</p><p>Pan-Arabism Nationalist notion of cultural and political unity among  Arab countries. Its origins lie in the late 19th and early 20th centuries,  when increased literacy led to a cultural and literary renaissance among  Arabs of the Middle East. This contributed to political agitation and led  to the independence of most Arab states from the Ottoman Empire (1918)  and from the European powers (by the mid-20th century). An important  event was the founding in 1943 of the Ba'th Party, which formed branches  in several countries and became the ruling party in Syria and Iraq. Another  was the founding of the Arab League in 1945. Pan-Arabism�s most char�  ismatic and effective proponent was Egypt�s Gamal Abdel Nasser. After  Nasser�s death, Syria�s Hafiz al-Assad, Iraq�s Saddam Hussein, and Libya�s  Muammar al-Qaddafi tried to assume the mantle of Arab leadership.</p><p>Pan-Germanism Movement to politically unify all German-speaking  people. The desire for German unification began in the early 19th century  and was advanced by Ernst Arndt and other early nationalists. The Pan-  German League was organized in 1894 by Ernst Hasse (1846-1908) to  heighten German nationalist awareness, especially among German�  speaking people outside Germany. The movement, which pressed for Ger�  man expansion in Europe, gained support after World War I under the  Weimar Republic and was actively promoted by Adolf Hitler and the Nazi  Party. After Germany�s defeat in 1945 and the expulsion of Germans from  formerly German areas of eastern Europe, the movement declined.</p><p>Pan Gu or P'an Ku Vpan-'gu\ In Chinese Daoist legend, the first man.  He came forth from Chaos (an egg) with two horns, two tusks, and a hairy  body. He used his knowledge of yin-yang to separate heaven and earth,  set the Sun, Moon, stars, and planets in place, and divide the four seas.  He also shaped the earth by chiseling out valleys and stacking up moun�  tains. Another legend says that the universe derived from Pan Gu�s gigan�  tic corpse. His eyes became the Sun and Moon, his blood formed rivers,  his hair grew into trees and plants, and the human race sprang from para�  sites that infested his body. In art, he is often shown as a dwarf clothed  with leaves.</p><p>Pan-p'o See Banpo</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1440 I Pan-Slavism &#x25BA; panchayat raj</p><p>Pan-Slavism Movement to unite Slav peoples of eastern and central  Europe. It began in the early 19th century when Slav intellectuals stud�  ied their common cultures. Political goals for Slavic unity increased in  1848, when a Slav congress organized by Frantisek PALACKy met in Prague  to press for equal rights under Austrian rule. In the 1860s the movement  became popular in Russia, to which Pan-Slavs looked for protection from  Turkish and Austro-Hungarian rule; this led Russia and Serbia into wars  against the Ottoman Empire in 1876-77. In the 20th century, nationalist  rivalries among the Slav peoples prevented their effective collaboration.</p><p>Pan-Turkism Political movement of the late 19th and early 20th cen�  turies, which had as its goal the political union of all Turkic-speaking  peoples in the Ottoman Empire, Russia, China, Iran, and Afghanistan. The  movement, which began among the Turks in the Crimea and on the Volga,  initially sought to unite the Turks of the Ottoman and Russian empires  against growing Russian domination. Mustafa Kemal Ataturk, the father of  the Republic of Turkey, later de-emphasized Pan-Turkism, encouraging  Turkish nationalism only within Turkey.

It is bounded by the Caribbean Sea to the north and the Pacific Ocean to  the south. Area: 28,973 sq mi (75,040 sq km). Population (2005 est.):</p><p>indigenous Indian languages. Religion:</p><p>Christianity (predominantly Roman Catholic; also other Christians). Cur�  rency: balboa. Panama consists of three distinct areas: the lowlands (�hot  lands�; nearly nine-tenths of the country), the temperate lands, and the  highlands (�cold lands�). It has a market economy based on services,  mostly transportation, communications, and storage connected with the  Panama Canal as well as international banking and tourism. It is a repub�  lic with one legislative house; its head of state and government is the  president, assisted by vice presidents. The land was inhabited by Indians  when the Spanish arrived in 1501. The first successful Spanish settlement  was founded by Vasco Nunez de Balboa in 1511. Panama was part of the  Viceroyalty of New Granada until it declared its independence from Spain</p><p>in 1821 to join Colombia. In 1903 it revolted against Colombia and was  recognized by the U.S., to whom it ceded the Canal Zone. The completed  canal was opened in 1914; control of the canal passed to a joint U.S.-  Panamanian commission in 1979. An invasion by U.S. troops in 1989  overthrew the de facto ruler, Gen. Manuel Noriega. In 1999 the country  elected its first female president, Mireya Moscoso, and later that year the  canal came under the full control of Panama.</p><p>Panama Canal Lock-type canal, Panama. Extending across the Isth�  mus of Panama, it connects the Atlantic and Pacific oceans. It is about 50  mi (82 km) long from deepwater to deepwater, with an average depth of  43 ft (13 m). The width varies between 500 to 1,000 ft (150 to 300 m).  In 1881 a French company began constructing the canal, but the enter�  prise collapsed in 1889. Under a 1903 treaty Panama granted the U.S. the  Panama Canal Zone and the rights to build and operate a canal. Work  began in 1904; facing enormous obstacles, George Washington Goethals  directed the construction from 1907, and the canal opened on Aug. 15,  1914. The canal enabled ships traveling between the two oceans to avoid  the lengthy circumnavigation of South America and was a boon to world  commerce. After disputes over sovereignty, a 1977 treaty provided for  Panama to take control of the canal by 2000; it did so in 1999. Except  for small craft, no vessel can pass through the canal under its own power.  Ships are towed by electric locomotives, and it generally takes 15-20  hours to complete the passage (including waiting time). Sets of double  locks enable ships to pass in opposite directions simultaneously.</p><p>Panama Canal Zone See Canal Zone</p><p>Panama City City (pop., 2000: 415,964), capital of Panama. Near the  Pacific Ocean entrance of the Panama Canal, on the Bay of Panama, the  site was originally an Indian fishing village. The old city was founded in  1519 but was completely destroyed by British buccaneer Henry Morgan  in 1671. It was rebuilt in 1674 just west of the old site. In 1751 the area  became part of the Viceroyalty of New Granada and later part of Colom�  bia. It was the centre of the Panamanian revolt against Colombia in 1903,  when it became the capital of Panama. After the canal opened in 1914,  the city developed rapidly, becoming the commercial and transportation  centre of the country. The economy depends largely on revenue from canal  traffic and associated services.</p><p>Panathenaea \ I pan- l a-th3- , ne-o\ In Greek religion, an Athenian festi�  val of great antiquity. Originally an annual event, it was eventually cel�  ebrated every fourth year, probably in deliberate rivalry to the Olympic  Games. It consisted of the sacrifices and rites proper to the season (mid-  August) in the cult of Athena, the city�s protectress. Representatives of  all the dependencies of Athens came to the Panathenaea. The great pro�  cession, made up of the heroes of the Battle of Marathon, is the subject  of the frieze of the Parthenon. The participants offered Athena an embroi�  dered robe and sacrificed animals; there were also poetry recitations (later  replaced by a musical contest) and athletic competitions.</p><p>Panay \p3-'nl\ Island (pop., 2000: 3,643,016), westernmost of the  Visayan group, central Philippines. It is surrounded by the Sibuyan,  Visayan, and Sulu seas, and the Guimaras Strait separates it from Negros  island. Roughly triangular in shape, it has an area of 4,446 sq mi (11,515  sq km). A rugged, almost unpopulated mountain range parallels its west�  ern coastline. Between the range and a hilly eastern portion, a densely  populated, intensely farmed fertile plain extends north to south. The  island�s chief city is Iloilo.</p><p>Panchatantra Vpon-cho-'ton-troX Sanskrit "Five Treatises" or</p><p>"Five Chapters" Collection of Indian beast fables written in Sanskrit  that has had extensive circulation throughout the world. The original  work, now lost, may have been written down between 100 bc and ad 500.  A textbook for instructing three sons of a king, it contained aphorisms  that glorify shrewdness and cleverness over altruism. As early as the 11th  century one version reached Europe, where it was known as The Fables  of Bidpai (for the narrator, an Indian sage).</p><p>panchayat \pon-'cha-y3t\ raj In India, government by the village  council, or panchayat.

A Panchen Lama installed by the Chinese Nationalist govern�  ment in 1949 later became an official under the Chinese communists. He  remained in Tibet after the 14th Dalai Lama fled into exile in 1959 but  was imprisoned in 1964 after criticizing the government. He was released  in the late 1970s and died in 1989. The Dalai Lama and government sub�  sequently chose different successors.</p><p>pancreas \'paq-kre-3s\ Compound gland functioning as both an exo�  crine (secreting through a duct) and an endocrine (ductless) gland. It con�  tinuously secretes pancreatic juice (containing water, bicarbonate, and  enzymes needed to digest carbohydrates, fat, and protein) through the  pancreatic duct to the duodenum. Scattered among the enzyme-producing  cells are the islets of Langerhans, which secrete insulin and glucagon  directly into the bloodstream. Disorders include inflammation (pancreati�  tis), infections, tumours, and cysts. If more than 80-90% of the pancreas  must be removed, the patient will need to take insulin and pancreatic  extracts. See also diabetes mellitus; hypoglycemia.</p><p>pancreatic cancer Malignant tumour of the pancreas. Risk factors  include smoking, a diet high in fat, exposure to certain industrial prod�  ucts, and diseases such as diabetes and chronic pancreatitis. Pancreatic  cancer is more common in men. Symptoms often do not appear until pan�  creatic cancer is advanced; they include abdominal pain, unexplained  weight loss, and difficulty digesting fatty foods. Surgery, radiation therapy,  chemotherapy, or some combination of these may be used to treat the dis�  ease.</p><p>pancreatitis Vpaq-kre-o-'tl-tosX Inflammation of the pancreas, associated  with alcohol, trauma, or pancreatic-duct obstruction. Activated enzymes  escaping into pancreatic tissues cause irritation and inflammation. If it  does not subside, bleeding, tissue death and scarring, pus formation, and  infection may occur. Symptoms include severe pain (worst when lying on  the back), low fever, nausea, and hypertension. Acute cases are treated by  controlling pain, preventing or relieving shock, inhibiting pancreatic-juice  secretion (including eliminating oral intake of food), avoiding infection,  and replacing lost fluids and salts. Chronic pancreatitis can destroy enough  of the pancreas to cause pancreatic-juice deficiency and diabetes mellitus.  Treatment may include a low-fat diet, avoiding overeating and alcohol,  pancreatic extracts, and insulin.</p><p>panda or giant panda Species (Ailuropoda melanoleuca, family  Ursidae) of white-and-black forest�  dwelling carnivore, found in central  China, that subsists almost exclu�  sively on bamboo. Because they can�  not digest cellulose, wild pandas (of  which there are about 1,600) spend  as much as 16 hours a day eating up  to 40 lb (18 kg) of bamboo leaves,  stems, and shoots to obtain needed  nutrients. More than 120 individuals  live in captivity, mostly in China.</p><p>Large males may attain 6 ft (1.8 m)  in length and weigh more than 220  lb (100 kg); females are usually  smaller. Giant pandas live alone except when breeding. They have a slow  reproductive cycle and are difficult to breed in captivity.</p><p>panda, lesser or cat bear or bear cat Long-tailed nocturnal rac�  coonlike carnivore (Ailurus julgens , family Procyonidae) that inhabits  high mountain forests in the Himalayas and adjacent eastern Asia. It is  20-26 in. (50-65 cm) long, excluding the 12-20-in. (30-50-cm) bushy,  faintly ringed tail. It weighs 6-10 lbs (3�4.5 kg) and has soft, thick, red�  dish brown fur. The face is white, with a red-brown stripe from the eyes  to the mouth. It eats plants, especially bamboo, and fruits and insects.  Though an agile climber, it mostly feeds while on the ground.</p><p>Pandora In Greek mythology, the first woman. After Prometheus stole  fire from heaven and bestowed it on mortals, Zeus decided to counteract  this blessing and commissioned Hephaestus to fashion a woman out of</p><p>earth, upon whom the gods bestowed their choicest gifts. After marrying  Prometheus�s brother, Pandora opened ajar containing all kinds of mis�  ery and evil, which escaped and flew out over the earth. In one version,  Hope alone remained inside, the lid having been shut before she could  escape.</p><p>panegyric \,pa-n3-'jir-ik\ Eulogistic oration or laudatory discourse. The  panegyric originally was a speech delivered at an ancient Greek general  assembly (panegyris ), such as the Olympic and Panathenaic festivals.  Speakers frequently advocated Hellenic unity by expounding on the  former glories of Greek cities; hence the elaborate and flowery connota�  tions of the term. Later Roman speakers praised and flattered eminent  persons, especially emperors, in panegyrics. The form was also used in  the European Middle Ages, Renaissance, and Baroque era.</p><p>Pangea \pan-'je-o\ or Pangaea Hypothetical protocontinent pro�  posed by Alfred Wegener in 1912 as part of his theory of continental drift.  Pangea (from Greek: pangaia, �all earth�) supposedly covered about half  the Earth and was completely surrounded by a world ocean called Pan-  thalassa. Late in the Triassic Period (248-206 million years ago), Pangea  began to break apart. Its segments, Laurasia (composed of all the present-  day northern continents) and Gondwana (the present-day southern con�  tinents) gradually receded, resulting in the formation of the Atlantic  Ocean.</p><p>Pangkor Engagement Vpaq-,k6r\ (1874) Treaty between the British  government and Malay chiefs, named for the island where it was signed.  In return for British backing in a complicated Perak succession dispute.  Raja Abdullah accepted a British resident (adviser) with broad powers at  his court, the first step in the establishment of British dominion over the  Malay states.</p><p>pangolin Vparj-go-lonV or scaly anteater Any of about eight spe�  cies of armoured placental mammals (genus Manis, order Pholidota) of  tropical Asia and Africa. Scales formed of cemented hairs cover the upper  body, legs, and tail. Pangolins are 2-6 ft (60-180 cm) long and weigh  10-60 lb (5-27 kg). They have a conical head, no teeth, a long tongue,  short legs, and a long prehensile tail. Some are arboreal; terrestrial spe�  cies live in burrows. Nocturnal animals, pangolins locate prey, mainly  termites, by smell and rip open nests with their front claws. When threat�  ened, the pangolin (Malayan for �rolling over�) curls up or emits an odor�  iferous secretion. See also anteater; echidna.</p><p>panic In economics, a severe financial disturbance, such as widespread  bank failures, feverish stock speculation followed by a market crash, or a  climate of fear caused by economic crisis or anticipation of such a crisis.  The term is applied only to the initial, violent stage of financial upheaval  rather than the whole decline in the business cycle (see depression and reces�  sion). Until the 19th century, economic fluctuations were largely con�  nected with shortages of goods, market expansion, and speculation (as in  the South Sea Bubble). Panics in the industrialized societies of the 19th�  20th centuries have reflected the increasing complexity of advanced  economies. The Panic of 1857 in the U.S. had its seeds in the railroads�  defaulting on their bonds and in the  decline in the value of railroad secu�  rities; its effects were complex,  including not only the closing of  many banks but also severe unem�  ployment in the U.S. and a money-  market panic in Europe. The Panic of  1873, which began with financial cri�  ses in Vienna and New York, marked  the start of a long-term contraction in  the world economy. The most infa�  mous panic began with the U.S.  stock-market crash of 1929 (see  Great Depression).</p><p>Panjabi language See Punjabi</p><p>LANGUAGE</p><p>Pankhurst, Emmeline orig.</p><p>Emmeline Goulden (b.

In  1903, after holding municipal offices in Manchester, she founded the  Women�s Social and Political Union (WSPU). From 1912 she advocated  extreme militancy, mainly in the form of arson, and was arrested 12 times  in one year. Weeks before her death in 1928, Britain passed a bill to give  voting rights to all women. Her daughter Christabel H. Pankhurst (1880-  1958)�later Dame Christabel�organized the militant tactics of the  WSPU and directed actions that included hunger strikes and huge out�  door rallies. She later became a religious evangelist and moved to the U.S.</p><p>Pannini \pan-'ne-ne\, Giovanni Paolo or Giovanni Paolo  Panini (b. 1691, Piacenza, Duchy of Parma and Piacenza�d. 1765,  Rome) Italian painter. After gaining fame for his fresco painting, he spe�  cialized in Roman topography and became the foremost artist in that field  in the 18th century. His real and imaginary views of ancient Roman ruins  embody precise observation and tender nostalgia and combine elements  of late classical Baroque art with incipient Romanticism. His work was  popular both with tourists and his peers: he was admitted to the Academie  Fran^aise in 1732 and became its professor of perspective.</p><p>Pannonia Province, Roman Empire, corresponding to modern western  Hungary and parts of eastern Austria, Slovenia, and northern Serbia and  Montenegro. The original inhabitants were mainly Illyrians, with some  Celts in the western part. Conquered by Rome beginning in 35 bc, the  people of Pannonia revolted in ad 6, posing the greatest threat to the  empire since Hannibal�s invasion. Pannonia was split in ad 106, and Pan�  nonia Superior became a centre of the Roman wars under Marcus Aure�  lius. The Romans withdrew from the area after 395.</p><p>Panofsky \p9-'n6f-ske\, Erwin (b. March 30, 1892, Hannover,  Ger.�d. March 14, 1968, Princeton, N.J., U.S.) German-born U.S. art  historian. A professor at the University of Hamburg (1926-33), he fled  Nazi Germany for the U.S. and in 1935 began teaching at Princeton�s  Institute for Advanced Study. He gained prominence for his studies in  iconography, the study of symbols and themes in works of art. His writ�  ings are distinguished by their variety of subjects, critical penetration,  erudition, and rich allusions to literature, philosophy, and history. Among  his major works are the groundbreaking Studies in Iconology (1939),  Albrecht Diirer (1943), and Early Netherlandish Painting (1953).</p><p>panorama Narrative scene or landscape painted to conform to a curved  or flat background, which surrounds or is unrolled before the viewer.  Popular in the late 18th and 19th centuries, it was an antecedent of the  stereopticon and motion pictures. The true panorama is exhibited on the  walls of a large cylinder, and the viewer stands on a platform in the cyl�  inder�s centre and turns around to see all points of the horizon. The first  panorama, a view of Edinburgh, was executed in 1788 by the Scottish  painter Robert Barker (1739-1806). In the mid-19th century the rolled  panorama became popular: a painting on canvas was wound between two  poles and slowly unrolled behind a frame or revealed in sections.</p><p>panpipe or syrinx Wind instrument consisting of pipes of different  lengths made of cane (less often  wood, clay, or metal) arranged in a  row. It is blown across the top, each  pipe producing a different note. The  panpipe dates from c. 2000 bc and is  found worldwide, especially in east�  ern Africa, South America, and  Melanesia.</p><p>p'ansori Korean "story sing�  ing" A form of sung folk narrative.</p><p>The form seems to have originated  during the reign of Sukchong (1675-1720). Once a narrative performance  that incorporated shamanistic chants, p �ansori became a vehicle for treat�  ing popular customs and everyday life. Six of the original 12 titles were  revised by the master p�ansori writer Sin Chaehyo, of which five are still  performed.</p><p>pansy Any of several popular cultivated violets (genus Viola). Pansies  have been grown for so long under such diverse conditions with such  striking variations in colour and form that their origin is uncertain. Prob�  ably the garden pansy (V. wittrockiana) is a cultivated form of V. tricolor,  a weed of European grainfields. Annuals or short-lived perennials, pan�</p><p>sies grow 6-12 in. (15-30 cm) tall  and have heart-shaped leaves at the  base and oblong leaves growing  from the stems. Velvety flowers  occur in combinations of blue, yel�  low, and white. The smaller, usually  purple, wild pansy is also known as  Johnny-jump-up, heartsease, and  love-in-idleness.</p><p>pantheism Doctrine that the uni�  verse is God and, conversely, that  there is no god apart from the sub�  stance, forces, and laws manifested  in the universe. Pantheism character�  izes many Buddhist and Hindu doc�  trines and can be seen in such Hindu  works as the Vedas and the Bhaga-  vadgita. Numerous Greek philoso�  phers contributed to the foundations  of Western pantheism. In the Middle  Ages and the Renaissance, the tradi�  tion was continued in Neoplatonism  and Judeo-Christian mysticism. In the 17th century Benedict de Spinoza for�  mulated the most thoroughly pantheistic philosophical system, arguing  that God and Nature are merely two names for one reality.</p><p>Pantheon Building in Rome begun 27 bc, probably as an ordinary rect�  angular Classical temple, and com�  pletely rebuilt by Hadrian (c. ad 118-  128).

The nature of the bound form was  clarified through the discovery and synthesis (1947-50) of the compound  pantetheine, which contains pantothenic acid combined with the com�  pound thioethanolamine. Pantetheine is part of two larger compounds  (coenzyme A and acyl-carrier protein) that promote a large number of  metabolic reactions essential for the growth and well-being of animals.

Bishops led the early church, the bishop of Rome being  accorded special respect by the end of the 1st century ad in part because  of the belief that St. Peter was the first bishop of that city. St. Cyprian chal�  lenged that position of honour in the 3rd century, and in the 4th-5th cen�  tury the power of the see of Constantinople rose to challenge that of Rome;  the rivalry would culminate in the Schism of 1054 between the Eastern  and Western churches. After the collapse of the Roman Empire, the papacy  found protection under the wing of Charlemagne and his successors; in  the 9th-10th century the German emperors controlled it. In 1059 Pope  Nicholas II responded by vesting the right to name a new pope exclusively  with the College of Cardinals. To establish the papacy�s supremacy in  Christian society, Gregory VII excommunicated Henry IV of Germany for  disobedience to papal commands and decreed that civil rulers could not  invest churchmen with temporal power (see Investiture Controversy). In  the next centuries, the papacy developed into one of the most important  and influential institutions in Europe, and Urban II, Innocent HI. and Gre�  gory IX were among the most significant popes of the period. The world�  liness and corruption of the papal court that emerged at the same time and  the �Babylonian Captivity� of the papacy at Avignon (see Avignon papacy)  led to the Western Schism and eventually to the Reformation. The Council  of Trent inaugurated the Counter-Reformation. In the 19th century the  papacy lost its remaining temporal powers when the Papal States were  incorporated into the new Kingdom of Italy. It maintained a conservative  religious position, proclaiming infallibility in doctrinal matters and  espousing the idea that the pope is the absolute ruler of the church. The  Second Vatican Council gave the bishops, clergy, and laity more voice.  See also Roman Catholicism.</p><p>Papago Vpa-p9-,go\ or Tohono O'odham North American Indian  people linving mostly in a region straddling the U.S.-Mexico border. Their  language belongs to the Uto-Aztecan language stock. They rejected the  name Papago, from a Piman word papahvi-o-otam meaning �bean eat�  ers,� in the 1980s; they call themselves Tohono O�odham, meaning  �Desert People.� Closely related to the Pima, they probably descend from  ancient Hohokam peoples. On their traditional territory, vast stretches of  desert regions of Arizona, U.S., and northern Sonora, Mex., the Papago  practiced food gathering and flash-flood farming. Because of the wide  dispersal of their fields, their largest viable political unit was a group of  temporarily related villages. They had less contact with whites than other  Indian groups and have retained elements of their traditional culture. They  number some 15,000.</p><p>Papal Curia See Roman Curia</p><p>papal infallibility In Roman Catholicism, the doctrine that the pope,  acting as supreme teacher and under certain conditions, as when he speaks  ex cathedra (�from the chair�), cannot err when he teaches in matters of  faith or morals. It is based on the belief that the church, entrusted with  the teaching mission of Jesus, will be guided by the Holy Spirit in remain�  ing faithful to that teaching. The First Vatican Council (1869-70) stated  the conditions under which a pope may be said to have spoken infallibly:  he must intend to demand irrevocable assent from the entire church in  some aspect of faith or morals. The doctrine remains a major obstacle to  ecumenical endeavours and is the subject of controversy even among  Roman Catholic theologians.</p><p>Papal Inquisition See Inquisition</p><p>Papal States Italian Stati Pontifici Vsta-te-pon-'te-fe-che\ Territo�  ries of central Italy over which the pope had sovereignty from 756 to 1870.  The extent of the territory and the degree of papal control varied over the  centuries. As early as the 4th century, the popes had acquired consider�  able property around Rome (called the Patrimony of St. Peter). From the  5th century, with the breakdown of Roman imperial authority in the West,  the popes� influence in central Italy increased as the people of the area  relied on them for protection against the barbarian invasions. When the  Lombards threatened to take over the whole peninsula in the 750s, Pope  Stephen II (or III) appealed for aid to the Frankish ruler Pippin III (the  Short). On intervening, Pippin �restored� the lands of central Italy to the  Roman see, ignoring the claim of the Byzantine (Eastern Roman) Empire  to sovereignty there. This Donation of Pippin (754) provided the basis for  the papal claim to temporal power. More land was gained when the papacy  acquired the duchy of Benevento in 1077, and Popes Innocent III and Julius  II further expanded the papal domain. The rise of communes and rule by  local families weakened papal authority in the towns, and by the 16th  century the papal territory was one of a number of petty Italian states.  They were an obstacle to Italian unity until 1870, when Rome was taken  by Italian forces and became the capital of Italy. In 1929 the Lateran Treaty  settled the pope�s relation to the Italian state and set up an independent  city-state (see Vatican City).</p><p>Papandreou V.pa-pan-'dra-iA, Andreas (Georgios) (b.

In 1935 he founded the Democratic Socialist Party,  then went into exile. He briefly headed a coalition government in 1944,  then held ministerial posts (1946-52). He merged his party with the Lib�  eral Party and formed the Centre Union in 1961. As prime minister in  1964 he introduced far-reaching social reforms, but he was dismissed by  the king in 1965.

The remaining water is removed by  evaporation, and the dry sheet is further compressed and often (depend�  ing on the intended use) coated or infused with other substances. Types  of paper in common use include bond paper, book paper, bristol (or bris-  tol board), groundwood and newsprint, kraft paper, paperboard, and sani�  tary paper (for towels, napkins, etc.). See also calendering; Fourdrinier  MACHINE; KRAFT PROCESS.</p><p>paper birch Ornamental, shade, and timber tree (Betula papyrifera) of  the birch family, native to northern and central North America. Also called  canoe birch, silver birch, or white birch, it is one of the best-known  birches. The smooth, varicolored or white bark of young trees peels hori�  zontally in thin sheets, which once were used as writing surfaces as well  as for roofing, canoes, and shoes. The water-impervious bark, which bums  even when wet, is a boon to campers and hikers.</p><p>paper chromatography (PC) Type of chromatography using filter  paper or other special paper as the stationary phase. Spots of sample and  reference materials are applied, usually as liquids, near one edge (or cor�  ner, for two-dimensional PC) of the paper. The edge of the paper is dipped  in a solvent, which travels along it by capillarity, moving the components  of the sample at rates depending on their relative solubilities in the sol�  vent. In two-dimensional PC, the paper is then turned 90� and the new  edge dipped in a different solvent. The components of the sample mix�  ture, visible as separated spots, are identified by comparing the distances  they have traveled with those of the known reference materials. PC is  especially useful for complex mixtures of amino acids, peptides, carbohy�  drates, steroids, and many other organic compounds and inorganic ions.</p><p>paper folding Japanese origami Art of folding objects out of paper  without cutting, pasting, or decorating. Its early history is unknown, but  it seems to have developed from the older art of folding cloth. Origami  has reached its greatest development in Japan, with hundreds of traditional  folds and an extensive literature dealing with the art. There are two types  of Japanese folds: figures used in ceremonial etiquette, and objects such  as animals, flowers, furniture, and human figures. Some objects have  amusing action features; best known is the bird that flaps its wings when  its tail is pulled. Paper folding has also flourished in Spain, South America,  and Germany.</p><p>Paphlagonia Ancient district, northern Anatolia, on the Black Sea. A  mountainous country, one of the oldest in Anatolia, it submitted to Alex�  ander the Great in 333 bc. In the 3rd-2nd century bc it was gradually  absorbed by the Pontic kingdom on its eastern border. In 65 bc the coastal  districts, including the capital, Sinope, were attached to Roman Bithynia.  The area was incorporated into the Roman province of Galatia in c. 6 bc;  the interior regions were left under native rulers. It was part of the Byz�  antine Empire, and all but its coastal regions were lost to invading Turk�  ish peoples after the Battle of Manzikert (1071).</p><p>papillomavirus X.pa-po-'lo-mo-.vI-rosX Any of a group of viRUSes that  cause warts and other harmless tumours in humans. More than 100 dis�  tinct types are known. Different types are responsible for warts of the  hands, plantar warts (of the feet), and throat warts. Genital warts are  caused by other types, which are spread by sexual intercourse. Some types  of papillomaviruses that cause genital infections have been linked with  various cancerous tumours, especially cervical cancers; their presence can  be detected through a Pap smear.</p><p>papillon \,pa-pe-'yo n \ Breed of toy dog known from the 16th century,  when it was called a dwarf spaniel. A favorite of Marie-Antoinette, it  appeared in paintings by Old Masters. It acquired its name (French for  �butterfly�) in the late 19th century, when a variety with large, flaring ears  became fashionable. Another variety has drooping ears. A slender, grace�  ful dog with a plumed tail, it stands 11 in. (28 cm) or less and weighs up  to 11 lbs (5 kg). The soft, full coat is usually white, with darker patches.</p><p>Papineau \pa-pe-'no\, Louis Joseph (b. Oct. 7, 1786, Montreal,  Que.�d. Sept. 23, 1871, Montebello, Que., Can.) Canadian politician. He  was elected to the legislative assembly of Lower Canada (now Quebec)  in 1808 and became its speaker in 1815. A leader of the French-Canadian  Party, he opposed the British-dominated government of Lower Canada.  In 1834 he helped draft the 92 Resolutions, a statement of French-  Canadian demands and grievances. When the British governor rejected  the resolutions, hostilities broke out. Papineau escaped to the U.S. and  then to France, where he lived from 1839 to 1844. He returned to Canada  under an amnesty in 1844 and served in the Canadian House of Com�  mons from 1848 to 1854, though he never regained his leadership of the  French-Canadians.</p><p>Papp, Joseph orig. Joseph Papirofsky (b. June 22, 1921, Brook�  lyn, N.Y., U.S.�d. Oct. 31, 1991, New York, N.Y.) U.S. theatrical pro�  ducer and director. He studied acting and directing and worked as a stage  manager for CBS television. In 1954 he founded the New York Shakes�  peare Festival, which gave free performances of Shakespeare�s plays in  city parks. He produced and directed most of the plays; in 1962 the Dela-  corte Theatre in Central Park was built as the company�s permanent home.  In 1967 he founded the New York Shakespeare Festival Public Theatre,  which concentrated on contemporary and experimental dramas. Several  productions traveled to Broadway, including Hair (1967) and A Chorus  Line (1975). Papp remained one of Off-Broadway� s most active produc�  ers into the 1980s. He served as artistic director of the Shakespeare Fes�  tival and the Public Theatre until his death.</p><p>Papua formerly Irian Jaya Province (pop., 2000 prelim.: 2,220,934),  Indonesia. It includes the western half of the island of New Guinea and  its offshore islands and the Schouten and Raja Ampat island groups. The  Maoke Mountains rise to 16,503 ft (5,030 m) at Puncak Jaya. First sighted  by the Portuguese in 1511, Papua was claimed by the Dutch in 1828. It  was transferred to Indonesia in 1963 and was made a province in 1969,  with its capital at Jayapura. Rebels led a separatist movement there in the  late 1990s, and Papua achieved greater autonomy in 2001.</p><p>Papua New Guinea Vpa-pyu-w3...'gi-ne\ officially Independent  State of Papua New Guinea Island country, southwestern Pacific  Ocean. Area: 178,704 sq mi (462,840 sq km). Population (2005 est.):  5,887,000. Capital: Port Moresby. Most of the people are Papuan (four-  fifths) and Melanesian; ethnic minorities are Polynesian, Chinese, and  European. Languages: English (official), Tok Pisin, Motu, indigenous lan�  guages. Religions: Christianity (Protestant, Roman Catholic); also tradi�  tional beliefs. Currency: kina. The island of New Guinea constitutes about  seven-eighths of the total land area of Papua New Guinea; the country  also includes Bougainville Island and the Bismarck Archipelago. The New  Guinea terrain ranges from swampy lowland plains in the south and north  to high central mountains (the highlands) in the northwest and southeast.  Much of the land is covered with tropical rainforest. Some of the outly�  ing islands are volcanic. The country has a developing mixed economy  based largely on subsistence agriculture and the export of minerals. It is  a constitutional monarchy with one legislative house; its chief of state is  the British monarch represented by the governor-general, and the head of  government is the prime minister. The area has been inhabited since pre�  historic times, and farming has been practiced since c. 7000 bc. The Por�  tuguese sighted the coast in 1511, and the first European landing was  about 1526-27. The first European colony was founded in 1793 by the  British. In 1828 the Dutch claimed the western half as part of the Dutch  East Indies. In 1884 Britain annexed the southeastern part and Germany</p><p>Papen</p><p>CAMERA PRESS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Papuan languages &#x25BA; Paraguana Peninsula I 1445</p><p>'140�</p><p>'150�</p><p>0�</p><p>Equator</p><p>NINIGO</p><p>GROUP</p><p>ADMIRALTY ISLANDS ^</p></section><section><p><strong>Lorengau</strong></p><p>PA CI FI C  OCEAN</p><p>Mt.

In 1906  the British part (renamed Papua) passed to  Australia, which also governed the Ger�  man sector after World War I. After World  War II, Australia governed both sectors as  the Territory of Papua and New Guinea. Dutch New Guinea was annexed  to Indonesia in 1969. Papua New Guinea achieved independence in 1975  and joined the British Commonwealth. By the mid-1990s the government  of Papua New Guinea was seeking to resolve a long-standing conflict with  Bougainville independence fighters, and in 2001 the two sides agreed on  a peace treaty; Bougainville became an autonomous region in 2005.</p><p>Papuan Vpa-pyo-wonV languages Group of about 750 languages  spoken by indigenous peoples of New Guinea and parts of some neigh�  bouring islands, including Alor, Bougainville, Halmahera, New Britain,  New Ireland, and Timor. Spoken by perhaps five million people, Papuan  languages belong to about 60 families, the higher genetic relationships of  which are still uncertain. This diversity, conjoined with the numerous  Austronesian languages spoken on smaller parts of New Guinea and on  adjacent islands, makes the region the most linguistically heterogeneous  area of the world. The vast majority of Papuan languages have fewer than  100,000 speakers; among those with more are Chimbu and Enga, spoken  in the highlands of Papua New Guinea.</p><p>papyrus \p3-'pl-r9s\ Writing material of ancient times and the plant  from which it comes, Cyperus papyrus (sedge family), also called paper  plant. This grasslike aquatic plant has woody, bluntly triangular stems and  grows to about 15 ft (4.6 m) high in quietly flowing water up to 3 ft (90  cm) deep. The ancient Egyptians used the stem of the plant to make sails,  cloth, mats, cords, and principally paper. Paper made from papyrus was  the chief writing material in ancient Egypt, Greece, and Rome. In the  8th-9th century ad, other plant fibres replaced papyrus in the manufac�  ture of paper. The plant is now often used as a pool ornamental in warm  areas or in conservatories.</p><p>Para \pa-'ra\ River Channel of the Amazon River. It passes to the south  and east of Marajo Island, in northeastern Para state, northern Brazil, and  is about 200 mi (320 km) long and 40 mi (64 km) wide at its mouth. It  carries a small part of the discharge of the Amazon east and north to the  Atlantic Ocean, and its entire length is navigable.</p><p>parabola Npo-'ra-bo-loV Open curve, one of the conic sections. It results  when a right circular cone intersects a plane that is parallel to an edge of  the cone. It is also the path of a point moving so that its distance from a  fixed line (directrix) is always equal to its distance from a fixed point  (focus). In analytic geometry its equation is y = ax 2 + bx + c (a second-  degree, or quadratic, polynomial function). Such a curve has the useful</p><p>property that any line parallel to its axis of symmetry reflects through its  focus, and vice versa. Rotating a parabola about its axis produces a sur�  face (paraboloid) with the same reflection property, making it an ideal  shape for satellite dishes and reflectors in headlights. Parabolas occur  naturally as the paths of projectiles. The shape is also seen in the design  of bridges and arches.</p><p>Paracel \,par-9-'sel\ Islands Chinese Xisha Qundao or Hsi-sha  Ch'un-tao Vshe-.sha-'chim-'daiA Vietnamese Quan Dao Hoang Sa  Vkwan-'dau-'hwaq-'saV Group of about 130 small coral islands and reefs.  South China Sea, east of central Vietnam and southeast of Hainan Island,  China. The low, barren islands, none of which exceeds 1 sq mi (2.5 sq  km) in area, lack fresh water, and there are no permanent human resi�  dents. In 1932 the islands were claimed by French Indochina, and Japan  occupied some of them during World War II. China, Taiwan, and Vietnam  all claim them. In 1974 China assumed control, and they have remained  a matter of contention.</p><p>Paracelsus \,par-3-'sel-s3s\ orig. Philippus Aureolus Theo�  phrastus Bombastus von Hohenheim (b. Nov. 11 or Dec. 17,  1493, Einsiedeln, Switz.�d. Sept. 24, 1541, Salzburg, Archbishopric of  Salzburg) German-born Swiss physician and alchemist. He claimed to  have received his doctoral degree at the University of Ferrara. He adopted  the name �para-Celsus��meaning �beyond Celsus� (the Roman author�  ity on medicine)�and wandered throughout Europe and the Middle East,  studying with alchemists. He valued the common sense of common people  more than the dry teachings of Aristotle, Galen, and Avicenna and stressed  nature�s healing power. All were welcome at his lectures (which he gave  in German, not Latin) at the University of Basel, but such broadminded�  ness scandalized the authorities, and eventually he was forced to flee the  city. His written works include Great Surgery Book (1536). He anticipated  by centuries the treatment of syphilis by mercury compounds, the real�  ization that inhaled dust causes miners� silicosis, and homeopathy, and he  was the first to connect goitre with minerals in drinking water.</p><p>parachute Umbrella-like device for slowing the descent of a body fall�  ing through the atmosphere. Separate panels sewn together form a canopy  attached by suspension lines to a harness worn by the user. Originally  designed to provide a safe escape from a disabled aircraft, parachutes are  also used for dropping supplies and for slowing returning space capsules.  The parachute was conceived by the 14th century, but practical demon�  strations began only in the 1780s in France, leading in 1797 to a 3,200-ft  (1,000-m) exhibition jump from a balloon by Andre-Jacques Garnerin  (1769-1823); in 1802 he made a jump of 8,000 ft (2,400 m). Early para�  chute material was canvas, which was later replaced by silk and then  nylon. See also skydiving.</p><p>Paraclete See Holy Spirit</p><p>paradox Apparently self-contradictory statement whose underlying  meaning is revealed only by careful scrutiny. Its purpose is to arrest atten�  tion and provoke fresh thought, as in the statement �Less is more.� In  poetry, paradox functions as a device encompassing the tensions of error  and truth simultaneously, not necessarily by startling juxtapositions but  by subtle and continuous qualifications of the ordinary meanings of words.  When a paradox is compressed into two words, as in �living death,� it is  called an oxymoron.</p><p>paradoxes of Zeno \'ze-,no\ Arguments by which Zeno of Elea  upheld the doctrine of Parmenides that real Being is unique and unchang�  ing. Zeno�s arguments were aimed at discrediting the beliefs in plurality  and motion that were inconsistent with Parmenides� doctrine. His best-  known arguments are those against the reality of motion. One argument  begins from the fact that a body in motion can reach a given point only  after having traversed half the distance. But before traversing half, it must  traverse half of this half, and so on ad infinitum; consequently, the goal  can never be reached.</p><p>paraffin Paraffin wax, a mixture of organic compounds traditionally  derived from petroleum but also obtained synthetically.

Area: 157,048 sq mi  (406,752 sq km). Population (2005 est.): 5,905,000. Capital: Asuncion.</p><p>Most Paraguayans are mestizos; there are  much smaller groups of American Indians  and people of African, European, and  Asian ancestry. Languages: Spanish and  Guarani (both official). Religion: Chris�  tianity (predominantly Roman Catholic; also Protestant). Currency:  guarani. Paraguay is a landlocked country of plains and swampland. The  Paraguay River, flowing from north to south, divides the country into two  geographic regions: the eastern region, which is an extension of the Bra�  zilian Plateau; and the western region, which forms the northern part of  the Gran Chaco plains. Paraguay has a developing market economy that  is based largely on agriculture, trade, and light industries. It is a republic  with two legislative houses; its head of state and government is the presi�  dent. Seminomadic tribes speaking Guarani were in the area long before  it was settled by Spain in the 16th-17th century. Paraguay was part of the  Viceroyalty of the Rio de la Plata until it became independent in 1811. It  suffered from dictatorial governments in the 19th century and was dev�  astated by the War of the Triple Alliance (1864, 1865-70), which it fought  against Brazil, Argentina, and Uruguay. The Chaco War (1932-35), with  Bolivia over territorial rights in the Gran Chaco, was settled primarily in  Paraguay�s favour by the peace treaty of 1938. Military governments,  including that of Alfredo Stroessner, predominated from the mid-20th  century until a civilian president, Juan Carlos Wasmosy, was elected in  1993. The country suffered from a financial crisis beginning in the late  1990s.</p><p>Paraguay River River, South America. The fifth largest river in South  America, it is 1,584 mi (2,550 km) long and the principal tributary of the  Parana River. Rising in the Mato Grosso region of Brazil about 980 ft  (300 m) above sea level, it crosses Paraguay to its confluence with the  Parana near the Argentine border. The Gran Chaco plain extends west  from the river.</p><p>Paraguayan War See War of the Triple Alliance</p><p>Paraiba do Sul X.pa-ra-'e-bo-dii-'suH River River, eastern Brazil. It  is formed by the confluence of the Paraitinga and Paraibuna rivers east  of Sao Paulo; it flows east-northeastward and forms part of the border  between Minas Gerais and Rio de Janeiro states before emptying into the</p><p>Atlantic Ocean after a course of about 700 mi (1,100 km). Its lower course  is navigable, and it plays a vital role in Brazil�s social and economic life.</p><p>parakeet Any of 115 species in 30 genera (subfamily Psittacinae) of  small, slender seed-eating parrots  with a long, tapering tail. Parakeets  are found worldwide in warm  regions. They typically form large  flocks. Most species lay four to eight  eggs in a tree hole. The most popu�  lar caged parakeet is the budgerigar  (Melopsittacus undulatus), mistak�  enly called lovebird; about 8 in. (19  cm) long, it may be any colour but  usually has cheek spots and close  barring on the upper parts.</p><p>parallax \'par-3-laks\ Difference  in the direction of a celestial object  as seen by observers from two  widely separated points, a measure�  ment used to find a body�s distance.</p><p>The two positions of the observers and that of the object form a triangle;  its apex angle (at the object) is twice the parallax, which becomes smaller  with increasing distance. Observations for calculating the Sun�s parallax  can be made simultaneously from two different places on Earth�s surface;  that value reaches a maximum of 8.794 seconds of arc for observers at  points separated by Earth�s diameter. Observing the difference in an  object�s position as seen from Earth at points six months apart in its orbit  (stellar, or annual, parallax) allows measurements of distances (e.g., of  stars) too large to be made from two places on Earth�s surface. The near�  est star system, Alpha Centauri, has a stellar parallax of 0.76 second of  arc. Highly precise parallaxes, and thus the positions, of more than  100,000 stars in the Sun�s vicinity were determined from data collected  by the European Space Agency�s Hipparcos satellite (launched 1989).</p><p>parallel bars Event in men�s gymnastics in which a pair of wooden  bars supported horizontally above  the floor at the same height is used  to perform acrobatic feats. Competi�  tors combine swings and vaults with  stationary positions requiring  strength and balance, though swings  and vaults must predominate. It has  been included as an Olympic gym�  nastics event since the modem  games began in 1896. See also  UNEVEN PARALLEL BARS.</p><p>parallel evolution Evolution of  geographically separated groups in  such a way that they show physical  resemblances. A notable example is  the similarity between the marsupial  mammals of Australia and placental  mammals elsewhere, which have  arrived at remarkably similar forms  through the separate courses of their  evolution.</p><p>parallel postulate One of the</p><p>five postulates, or axioms, of Euclid  underpinning Euclidean geometry. It  states that through any given point not on a line there passes exactly one  line parallel to that line in the same plane. Unlike Euclid�s other four pos�  tulates, it never seemed entirely self-evident, as attested by efforts to prove  it through the centuries. The uniqueness of Euclidean geometry, and the  absolute identification of mathematics with reality, was broken in the 19th  century when Nikolay Lobachevsky and Janos Bolyai (1802-60) indepen�  dently discovered that altering the parallel postulate resulted in perfectly  consistent non-Euclidean geometries.</p><p>paralysis or palsy Loss or impairment of voluntary use of one or more  muscles. It may be flaccid (with loss of muscle tone) or spastic (stiff).  Hemiplegia (one-sided paralysis) is usually caused by stroke or brain  tumour on the opposite side. Diplegia (two-sided paralysis, as in cerebral  palsy) results from generalized brain disease.

Poliomyelitis and polyneuritis  (neuritis of multiple nerves) result in paralysis with muscle wasting. Bell  palsy (a type of neuritis) paralyzes the muscles of one side of the face.  Muscular dystrophy causes paralysis by attacking muscle. Metabolic  causes include myasthenia gravis. Paralysis may also have psychiatric  causes (see hysteria).</p><p>paramagnetism Kind of magnetism that occurs in materials weakly  attracted by a strong magnet. Compounds containing iron, palladium,  platinum, and the rare-earth elements exhibit strong paramagnetism  because they have atoms with some incomplete inner electron shells. Their  unpaired electrons make the atoms behave like tiny permanent magnets  that align with and strengthen an applied magnetic field. As the tempera�  ture rises, strong paramagnetism decreases because of the greater random  motion of the atoms. Weak paramagnetism, found in many solid metallic  elements, is independent of temperature.</p><p>Paramaribo \,pa-ra-'ma-re-bo\ City (pop., 1999 est.: 233,000), sea�  port, and capital of Suriname. Located on the Suriname River near the  Atlantic Ocean, it was originally an Indian village before becoming a  French settlement (c. 1640). In 1651 it became a British colony but was  ceded to the Dutch in 1667. It is built on a shingle reef that stands 16 ft  (5 m) above the river at low tide. Much of the distinctive Dutch colonial  architecture and a canal system remain. Since 1945 the city has grown  considerably because of tourism and industries.</p><p>paramecium V.par-o-'me-se-onA Any of the free-living, single-celled  protozoans that make up the genus Paramecium. Most are about the size  of the period at the end of this sentence. They vary in shape and are sur�  rounded by a rigid protein layer (pellicle) covered with hundreds of cilia  that beat rhythmically to propel them and to direct bacteria and other food  particles into their oral groove. Food particles are collected into food vac�  uoles, where digestion takes place. Two (occasionally three) contractile  vacuoles close to the surface near the ends of the cell expand and con�  tract as they discharge metabolic wastes and excess fluid. Paramecia have  two kinds of nuclei: a large macronucleus (the centre of all metabolic  activities) and at least one small micronucleus (which stores the genetic  material necessary for sexual reproduction). See illustration opposite.</p><p>Paramount Communications Media and communications corpo�  ration. It was founded (as Paramount Pictures Corp.) by W. W. Hodkin-  son in 1914 as a film distributor. It became a motion-picture company  two years later and won attention with stars such as Mary Pickford, Glo�  ria Swanson, and Rudolph Valentino. In the late 1920s and 1930s the stu�  dio added Claudette Colbert, Gary Cooper, and Marlene Dietrich to its roster.  Forced to declare bankruptcy after its chain of theaters suffered losses  during the transition to sound, the company was reorganized two years  later as Paramount Pictures, Inc. Among its successes of the 1940s and  �50s were the films of Preston Sturges and Billy Wilder. In 1966 Gulf &amp;  Western Industries took control of Paramount, and the new company later  changed its name to Paramount Communications. In 1994 it was acquired  by Viacom Inc., which in 2000 merged with CBS.</p><p>Parana \,pa-ra-'na\ River River, South America. It is the continent�s  second longest river (after the Amazon River) and rises on the plateau of  southeast-central Brazil. It flows generally south 3,032 mi (4,880 km) to  join the Uruguay River and form the Rio de la Plata estuary on the Atlan�  tic Ocean. Its drainage basin includes most of southeastern Brazil, Para�  guay, eastern Bolivia, and northern Argentina. From its origin at the  confluence of the Grande and Paranafba rivers to its junction with the  Paraguay River, it is known as the Alto (Upper) Parana. Completion of the  Itaipii Dam between Paraguay and Brazil in the 1980s submerged the  massive Guafra Falls and created a large reservoir.</p><p>paranoia Mental disorder characterized by delusions of persecution or  grandeur, usually without hallucinations. Paranoia was formerly classified  as a distinct psychosis but is now generally treated as one of several vari�  eties of schizophrenia or, in milder cases, of personality disorder. The para�  noid person generally suffers from exaggerated self-reference, a tendency  to construe independent events and acts as pertaining to him- or herself.</p><p>parapsychology V.par-o-.sI-'ka-b-jeV Discipline concerned with  investigating events that cannot be accounted for by natural law and  knowledge that cannot have been obtained through the usual sensory</p><p>cytosome</p><p>(gullet)</p><p>food</p><p>vacuole</p><p>General features of a paramecium.</p><p>� MERRIAM-WEBSTER INC.</p><p>abilities. Parapsychology studies the cognitive phenomena often called  extrasensory perception, in which a person acquires knowledge of other  people�s thoughts or of future events through channels apparently beyond  the five senses. It also examines physical phenomena such as the levita�  tion of objects and the bending of metal through psychokinesis. Though  belief in such phenomena may be traced to earliest times, parapsychol�  ogy as a subject of serious research originated in the late 19th century,  partly in reaction to the growth of the spiritualist movement. The Society  of Psychical Research was established in London in 1882, and similar  societies were later founded in the U.S. and in many European countries.  In the 20th century research into parapsychology was also conducted at  some universities, notably at Duke University under J. B. Rhine.</p><p>parasitism Vpar-o-so-.ti-zomX Relationship between two species in  which one benefits at the expense of the other. Ectoparasites live on the  body surface of the host; endoparasites live in their hosts� organs, tissues,  or cells and often rely on a third organism (the carrier, or vector) to trans�  mit them to the host. The cuckoo and cowbird practice brood parasitism,  laying eggs in other birds� nests to be raised by the foster parents. In social  parasitism, one type of animal parasitizes animals of the same type (e.g.,  one ant species on different ant species). Hyperparasitism occurs when  parasites are parasitized (e.g., protozoans hyperparasitize a flea on a dog).  See also predation.</p><p>parathyroid gland Endocrine gland, two to eight of which are  embedded in each side of the thyroid gland. It secretes parathyroid hor�  mone, which regulates blood calcium and phosphorus levels. When cal�  cium in body fluids drops, increased hormone secretion releases calcium  from bone into the bloodstream (see calcium deficiency). The hormone also  increases excretion of phosphate in the urine, lowering blood concentra�  tions, and may play a role in magnesium metabolism. When thyroid  removal is required, the parathyroid glands must be separated out and left  in place. See also endocrine system.</p><p>parchment Processed skins of certain animals (chiefly sheep, goats,  and calves) that have been prepared for the purpose of writing on them.  Parchment was probably invented in Greece in the 2nd century bc. Skins  had been used for writing material even earlier (c. 2400 bc), but the new,  more thorough method of cleaning, stretching, and scraping made pos�  sible the use of both sides of a manuscript leaf, leading to the replace-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1448 I pardo &#x25BA; Paris</p><p>ment of the rolled manuscript by the bound book (codex). Especially fine  parchment is known as vellum. In modern usage, the terms �parchment�  and �vellum� are sometimes used for a type of high-quality paper.</p><p>pardo Spanish "brown" In Venezuela, a person of mixed African,  European, and Indian ancestry. In the colonial period, pardos, like all  nonwhites, were kept in a state of servitude, with no hope of gaining  wealth or political power. Nevertheless, most pardos remained royalists  during much of the war for independence because they relied on Spain  for protection in their conflicts with the Venezuelan-born whites, toward  whom the European Spaniards took a superior attitude. In Brazil a pardo  is a person of mixed European and African descent.</p><p>pardon In law, release from guilt or remission of punishment. The  power to pardon is generally exercised by the state�s chief executive  officer. A pardon may be full or conditional. A conditional pardon imposes  a lesser punishment or some other obligation. Some states still bar par�  doned offenders from holding public office or obtaining professional  licenses.</p><p>Pare \pa-'ra\, Ambroise (b. 1510, Bourg-Hersent, France�d. Dec. 20,  1590, Paris) French physician and surgeon. Employed as an army sur�  geon in 1537, Pare preferred measures less drastic than those of other sur�  geons at the time (whose techniques included castration in hernia surgery  and searing large arteries with hot irons during amputation) and operated  only when necessary. He introduced the implantation of gold and silver  teeth, artificial limbs, and artificial eyes (see prosthesis) and invented many  instruments, popularized the truss for hernias, and first suggested that  syphilis caused aneurysms. He published books on a wide variety of  medical matters; his surgical works were especially influential.</p><p>Pareto \pa-'re-to\, Vilfredo (b. July 15, 1848, Paris, France�d. Aug.  19, 1923, Geneva, Switz.) Italian economist and sociologist. Educated at  the University of Turin, he worked as an engineer and later served as a  director of a large Italian railway. He taught at the University of Lausanne  from 1893. His law of income distribution used a complex mathematical  formula to trace historical patterns in the distribution of wealth. In 1906  he laid the foundation of modern welfare economics with his Pareto Opti�  mum, which stated that a society�s resources are not optimally allocated  as long as it is possible to make at least one person better off while keep�  ing others as well off as before.</p><p>Parhae \'p6-'hl\ Chinese Pohai Vpo-'hA State established in the 8th  century ad in northern Manchuria and northern Korea. Founded by a  former Korean general, Tae Cho-yang, it was considered a successor state  to Koguryo, which had occupied much of the same territory before its con�  quest by Silla in 668. Like Silla, Parhae was a tributary state of Tang-dynasty  China. It traded with the nomadic tribes of the north and with China and  Japan. Parhae was conquered in 926 by the Khitan tribes almost 20 years  after their creation of the Liao dynasty on China�s northern borders.</p><p>pari-mutuel V.par-i-'myii-cho-woB Betting pool in which those who bet  on competitors finishing in the first three places share the total amount bet  minus a percentage for the management. First introduced in France c.  1870, it soon became one of the most popular methods of betting on horse  races internationally. Today computers calculate betting pools and current  odds on each horse and flash the figures to the public at regular intervals.  The system is used largely for off-track betting. Pari-mutuel betting is also  practiced in dog racing and jai alai.</p><p>Pari a \p3-'re-9\, Gulf of Inlet of the Caribbean Sea, between Venezu�  ela and Trinidad. Extending about 100 mi (160 km) from east to west and  40 mi (65 km) from north to south, it is linked with the Caribbean to the  north and the Atlantic Ocean to the south. Its ports, including Port-of-  Spain, Trinidad, handle shipments of petroleum, iron ore, and agricultural  products. In 1498, on his third voyage to the Western Hemisphere, Chris�  topher Columbus probably first sighted South America when he sailed into  the gulf.</p><p>Paricutin \pa-'re-ku-,ten\ Volcano, western Michoacan state, west-  central Mexico. It is about 9,210 ft (2,808 m) high and is one of the  youngest volcanoes on Earth. It began to erupt in an open field in 1943  and buried the village of Paricutin. The eruption finally ceased in 1952.</p><p>Parilia \p3-'ri-le-9\ Ancient Roman festival celebrated annually on April  21 in honor of the goddess Pales, protector of flocks and herds. It was  celebrated first by the early kings of Rome and later by the pontifex max-  imus. The Vestal Virgins opened the festival by distributing straw and the</p><p>ashes and blood of sacrificed animals. Ritual cleaning, anointing, and  adornment of herds and stalls followed. The celebrants jumped over a  bonfire three times to complete the rite of purification.</p><p>Paris In Greek mythology, a son of King Priam of Troy and his wife,  Hecuba. An evil portent prompted his parents to abandon him as an infant.  Unknown to them, he was raised as a shepherd, and as a young man he  was received home again after winning a boxing contest against Priam�s  other sons. Zeus chose him to determine which of three goddesses was  most beautiful� Hera, Athena, or Aphrodite. In the famous �judgment of  Paris,� he chose Aphrodite because she offered to help him win the most  beautiful woman alive. His seduction of Helen was the cause of the Tro�  jan War. Near the end of the war, Paris shot the arrow that killed Achilles  and soon afterward was himself killed.</p><p>Paris City (pop., 1999: 2,125,246; metro, area, 9,644,507), river port,  capital of France. It is now located on both banks of the Seine River. The  original settlement from which Paris evolved, Lutetia, was in existence  by the late 3rd century bc on an island in the Seine. Lutetia was captured  and fortified by the Romans in 52 bc. During the 1st century ad the city  spread to the left bank of the Seine. By the early 4th century it was known  as Paris. It withstood several Viking sieges (885-87) and became the  capital of France in 987, when Hugh Capet, the count of Paris, became  king. The city was improved during the reign of Philip II. who formally  recognized the University of Paris c. 1200. In the 14th-15th centuries its  development was hindered by the Black Death and the Hundred Years' War.  In the 17th�18th centuries it was improved and beautified. Leading events  of the French Revolution took place in Paris (1789-99). Napoleon III com�  missioned Georges-Eugene Haussmann to modernize the city�s infrastruc�  ture and add several new bridges over the Seine. The city was the site of  the Paris Peace Conference, which ended World War I. During World War  II Paris was occupied by German troops. It is now the financial, com�  mercial, transportation, artistic, and intellectual centre of France. The  city�s many attractions include the Eiffel Tower, Notre-Dame de Paris, the  Louvre, the Pantheon, Pompidou Centre, and the Paris Opera, as well as  boulevards, public parks, and gardens.</p><p>Paris, Congress of (1856) Conference in Paris to produce the treaty  that ended the Crimean War. The treaty was signed between Russia on  one side and France, Britain, Sardinia-Piedmont, and Turkey on the other.  It guaranteed the independence and territorial integrity of Turkey. Russia  was forced to surrender Bessarabia to Moldavia, warships of all nations  were barred from the Black Sea, and the Danube River was opened to  shipping of all countries. The congress also adopted the first codified law  of the sea, which banned privateering and defined a legal naval blockade.</p><p>Paris, Treaty of (1229) Treaty by which Raymond VII of Toulouse con�  ceded defeat to Louis IX of France after the Albigensian Crusade. It arranged  the marriage of Raymond�s daughter and Louis�s brother and provided  for the eventual return of Languedoc to the crown, thus destroying the  independence of the princes of the south.</p><p>Paris, Treaty of (1259) Peace treaty signed by Henry III of England  and Louis IX of France. It allowed the English to keep Aquitaine and nearby  territories but obliged Henry to acknowledge himself the vassal of the  French king. The agreement kept peace between England and France until  the outbreak of the Hundred Years' War in 1337.</p><p>Paris, Treaty of (1763) Treaty concluding the Seven Years' War  (including the French and Indian War). It was signed by Britain and  Hanover on one side and France and Spain on the other. France renounced  to Britain the mainland of North America east of the Mississippi, its con�  quests in India since 1749, and four West Indian islands. Britain restored  to France four other West Indian islands and the West African colony of  Goree (Senegal). In return for recovering Havana and Manila, Spain ceded  Florida to Britain and received Louisiana from the French.</p><p>Paris, Treaty of (1814) Treaty signed in Paris that ended the Napo�  leonic Wars between France and the Allies (Austria, Britain, Prussia, Rus�  sia, Spain, Sweden, and Portugal). The terms were generous to France,  since Napoleon had abdicated and the Bourbon dynasty was restored.  France was allowed to retain its boundaries of 1792 and ceded only sev�  eral islands to Britain. Other terms were left to be discussed later.</p><p>Paris, Treaty of (1815) Second treaty between France and the Allies,  following Napoleon�s Hundred Days and final defeat.

It grew out of the  cathedral schools of Notre-Dame and, with papal support, soon became  a great centre of Christian orthodox teaching. In the medieval period its  professors included St. Bonaventure, Albertus Magnus, and Thomas  Aquinas. Its most celebrated early college was the Sorbonne, founded c.  1257. The university declined somewhat under the impact of the Refor�  mation and Counter-Reformation. With the French Revolution and Napo�  leon�s reforms, teaching became more independent of religion and  politics. By the mid-20th century the university had again become a pre�  eminent scientific and intellectual centre. In May 1968 a Sorbonne stu�  dent protest grew into a serious national crisis. This led to decentralizing  reforms, the old university being replaced in 1970 by a system in Paris  and its suburbs called the Universities of Paris I-XIII.</p><p>Paris Commune or Commune of Paris (March 18-May 28, 1871)  Insurrection of Paris against the French government. After France�s defeat  in the Franco-Prussian War and the collapse of the Second Empire, the  republican Parisians feared that the conservative majority in the National  Assembly would restore the monarchy. On March 18 the National Guard in  Paris resisted orders to disarm, and after municipal elections were won by  the revolutionaries, they formed the Commune government. Factions  included the so-called Jacobins, who wanted the Paris Commune to control  the revolution (as its namesake had in the French Revolution); the Proud-  honists, socialist followers of Pierre-Joseph Proudhon who supported a fed�  eration of communes; and the Blanquistes, socialist followers of Auguste  Blanqui who demanded violent action. Government forces quickly sup�  pressed communes elsewhere in France, then entered Paris on May 21. In  a week of fierce fighting, they crushed the Communards, who had set up  barricades in the streets and burned public buildings, including the Tuile-  ries Palace. About 20,000 insurrectionists and 750 government troops were  killed. In the aftermath, the government took harsh repressive action;  38,000 suspects were arrested and more than 7,000 were deported.</p><p>Paris-Match \pa-re-'mach\ Weekly pictorial magazine published in  France since 1949 as the successor to L�Illustration (1843-1944). A popu�  lar news and current-events magazine aimed at the middle class, it fea�  tures picture-stories on such subjects as public affairs, entertainment,  fashion, and consumer products. Its format resembles that of Life, and it  is similarly noted for topicality and outstanding photography. Under the  ownership of Jean Prouvost (d. 1978), it achieved prestige and financial  success. It is now published by Hachette Filipacchi Medias, one of the  world�s largest magazine publishers.</p><p>Paris Opera or Opera Gamier \o-per-'a-garn-'ya\ also Theatre  Nationale de I/Opera Opera house in Paris designed by Charles  Gamier (1825-98). The extraordinarily lavish building, considered one of  the masterpieces of the Second Empire (Beaux-Arts style), was begun in  1861 and opened in 1875. The floor plan is as elaborate as the exterior.  The interior features generous circulation space, including a grand stair�  case and numerous richly decorated galleries, foyers, and corridors. The  designation also applies to the opera company in Paris that for more than  two centuries was the chief performer of serious operas and musical dra�  mas in the French language. One of the most venerable operatic institu�  tions in the world, it occupied Gamier�s building until 1990.</p><p>Paris Peace Conference (1919-20) Meeting that inaugurated the  international settlement after World War I. It opened on Jan. 12, 1919,  with representatives from more than 30 countries. The principal delegates  were France�s Georges Clemenceau, Britain�s David Lloyd George, the  U.S.�s Woodrow Wilson, and Italy�s Vittorio Emanuele Orlando, who with  their foreign ministers formed a Supreme Council. Commissions were  appointed to study specific financial and territorial questions, including  reparations. The major products of the conference were the League of  Nations; the Treaty of Versailles, presented to Germany; the Treaty of  Saint-Germain, presented to Austria; and the Treaty of Neuilly, presented  to Bulgaria. The inauguration of the League of Nations on Jan. 16, 1920,  brought the conference to a close. Treaties were subsequently concluded  with Hungary (Treaty of Trianon, 1920) and Turkey (Treaties of Sevres,  1920, and Lausanne, 1923).</p><p>parity In economics, equality in price, rate of exchange, purchasing  power, or wages. In international exchange, parity exists when the  exchange rate between two currencies makes the purchasing power of both</p><p>currencies equal. Adjustments to maintain parity can occur in the mar�  ketplace as prices change in response to supply and demand, or through the  intervention of national governments or international agencies such as the  International Monetary Fund. In U.S. agricultural economics, the term  parity is used for a system of regulating the prices of farm commodities,  usually by government price supports and production quotas, to guaran�  tee farmers the purchasing power they had in a past base period. Parity is  also used in personnel administration to establish equitable wage rates for  various classes of employees.</p><p>parity In physics, a property related to the symmetry of the wave func�  tion representing a system of fundamental particles. It plays an important  role in quantum mechanics in the description of a physical system. Parity  transformation replaces a system with a type of mirror image in which the  spatial coordinates describing the system are inverted, so that the coor�  dinates x, y, and z are replaced with -x, -y, and �z. If a system is iden�  tical to the original system after parity transformation, its parity is even.  If the image is the negative of the original, its parity is odd. In either case,  the physical observables of the system remain unchanged. In 1957 Chien-  Shiung Wu (1912-1997) and coworkers made the surprising discovery  that beta decay reactions do not conserve parity; in other words, the  inverted image of the process does not exist in nature. This is a general  property of the WEAK FORCE.</p><p>park Large outdoor area set aside for recreation. The earliest parks were  hunting grounds of the Persian kings; such reserves became shaped by  riding paths and shelters. A second type of park derived from the open-  air meeting places of Greece, where the functions of an area for exercise,  social concourse, and athletes� training ground were combined with ele�  ments of a sculpture gallery and religious centre. Parks of post-  Renaissance times featured extensive woods, raised galleries, and often  elaborate aviaries and cages for wild animals. What often differentiates  present-day parks from parks of the past is their accommodation for active  recreation; facilities may include outdoor theatres, zoos, concert shells,  concessions for dining and dancing, amusement areas, boating areas, and  areas for sports.

Park had traveled to the East Indies before  being chosen by the African Association to head an expedition to find the  source of the Niger River (1795-97). He lost most of his crew and sup�  plies, was imprisoned and tortured for four months by hostile Arabs, and  suffered severe illness, reaching Segou (now in Mali) but not the river�s  source. His Travels in the Interior Districts of Africa (1797) became a  great popular success.

U.S. sociologist. After 11 years as a newspaper  reporter, Park attended various universities and studied with scholars such  as John Dewey, William James, Josiah Royce, and Georg Simmel. He then  worked for Booker T. Washington and later taught at the University of  Chicago�where he was a leading figure in the �Chicago school� of soci�  ology, characterized by empirical research and the use of human ecology  models�and at Fisk University. He is noted for his work on ethnic groups,  particularly African Americans, and on human ecology, a term he has been  credited with coining. Park wrote Introduction to the Science of Sociology  (1921) and The City (1925) with Ernest W.

He  was appointed to the New York Supreme Court in 1885, the state Appeals  Court in 1889, and the appellate division of the state Supreme Court in  1896. From 1898 to 1904 he was chief justice of the New York court of  appeals. On the bench, he was noted for upholding the rights of labour.  As the Democratic Party presidential candidate in 1904, he represented  the eastern, pro-gold-standard wing of the party. Soundly defeated by  Pres.

It was first described in 1817 by British physician James  Parkinson (1755-1824). The cause of primary parkinsonism, or Parkin�  son disease, is unknown. The mean age of onset is about 57, but juvenile  parkinsonism is also known. Neurons in the brain that normally produce  dopamine deteriorate. When 60-80% are destroyed, signals suppressing  unintended movement are disrupted and symptoms appear, including  tremor at rest, muscle rigidity, trouble in starting movements, and loss of  balance. Known causes include sleeping sickness; certain poisons; repeated  blows to the head, as in boxing; and the drug MPTP. Environmental tox�  ins or genetic susceptibility may account for some cases. Drug therapy  requires careful scheduling and combinations to delay development of  tolerance and side effects. Surgical pallidotomy (destruction of the glo�  bus pallidus, a brain structure involved in motor control) and transplan�  tation of fetal dopamine-producing tissue remain experimental.</p><p>Parkman, Francis (b.

His first work of fiction was The Learning Tree  (1963), a novel about a black adolescent in Kansas in the 1920s. He com�  bined poetry and photography in collections such as A Poet and His Cam�  era (1968) and Glimpses Toward Infinity (1996). In 1968 he became the  first African American to direct a major motion picture with his film  adaptation of The Learning Tree. He later directed Shaft (1971), which  helped give rise to the genre of African American action films known as  �blaxploitation.� Parks also composed music.</p><p>Parks, Rosa orig.

She worked as a seamstress in Montgomery, Ala., where she joined  the NAACP in 1943. In 1955 she was arrested after refusing to give her  seat on a public bus to a white man. The resultant boycott of the city�s  bus system, organized by Martin Luther King, Jr., and others, brought the  civil rights movement to new prominence. In 1957 Parks moved to Detroit,  where she was a staff assistant (1965-88) to U.S. Rep. John Conyers. She  was awarded the Congressional Gold Medal in 1999.</p><p>Parlement Vpar-b-montN Supreme court under the ancien regime in  France. It developed out of the curia regis (�king�s court�) in which the  Capetian kings convened their chief vassals and prelates to consider feu�  dal and political issues. By the mid-13th century this judicial institution  was known as Parlement and served as a court of appeals against the  judgments of royal officials. Later Parlements also reviewed the king�s  edicts to determine whether they were just and lawful. The chief Parle�  ment was located in Paris, and others were established in the provinces.  The Parlements were abolished in the French Revolution.</p><p>Parliament Legislative assembly of Britain and of other governments  modeled after it. The British Parliament consists of the monarch, the  House of Lords, and the House of Commons, and traces its roots to the  union (c. 1300) of the Great Council and the King�s Court, two bodies  that treated with and advised the king. In the 14th century, Parliament  was split into two houses, with the lords spiritual and temporal (i.e., not  only the nobility but also high officials of the church) debating in one and  the knights and burgesses in the other. In the 14th century Parliament also  began to present petitions (�bills�) to the king, which with his assent  would become law. Robert Walpole was the first party leader to head the  government as prime minister (1721-42). See also parliamentary democracy.</p><p>Parliament, Canadian Legislature of Canada, created by the British  North America Act. The 301 members of its House of Commons are  elected for maximum terms of five years from the provinces on the prin�  ciple of representation by population. The 105 members of its Senate are  appointed by Canada�s governor-general from the regions of Canada and  serve until age 75. The parliament has authority over the armed forces,  regulates trade and commerce, levies taxes, and is in charge of banking,  credit, currency and bankruptcy, criminal law, postal services, fisheries,  patents and copyrights, the census, navigation and shipping, railways,  canals, and telegraphs. It also retains powers not specifically assigned to  provincial legislatures. The leader of the party winning the most seats in  a general election becomes prime minister and is called on by the  governor-general to form a government. He generally chooses elected  party colleagues to form the cabinet. The party winning the second-largest  number of seats in the House becomes the official opposition party.</p><p>Parliament Act of 1911 Act passed in the British Parliament that  deprived the House of Lords of its absolute power of veto on legislation.  Proposed by a Liberal majority in the House of Commons, the act stated  that any bill passed unchanged by the Commons in three separate ses�  sions over two years could be presented for the royal assent (necessary  for a bill to become law) without the Lords� consent. By subordinating  the Lords to the Commons, the act was seen as another step in making  the British Constitution more democratic.</p><p>parliamentary democracy Democratic form of government in  which the party (or a coalition of parties) with the greatest representation</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>parliamentary procedure &#x25BA; parrot I 1451</p><p>in the parliament (legislature) forms the government, its leader becoming  prime minister or chancellor.

Parliamentary democracy originated in Britain (see Par�  liament) and was adopted in several of its former colonies.</p><p>parliamentary procedure or rules of order Generally accepted  rules, precedents, and practices used in the governance of deliberative  assemblies. They are intended to maintain decorum, ascertain the will of  the majority, preserve the rights of the minority, and facilitate the orderly  transaction of business. Rules of parliamentary procedure originated in  Britain in the 16th and 17th centuries and were subsequently adopted by  legislatures around the world. Robert�s Rules of Order, codified in 1876  by U.S. Gen. Henry M. Robert (1837-1923) and regularly refined and  enlarged, is the standard set of rules used by legislatures in the U.S.</p><p>Parma City (pop, 2001 prelim.: 156,172), Emilia-Romagna region, north�  ern Italy. Located on the Parma River, the site was founded by the Romans  in 183 bc; it became an episcopal see in the 4th century ad. Parma was  destroyed by the Ostrogoths under Theodoric I but was rebuilt in the  Middle Ages. Made part of the duchy of Parma and Piacenza in 1545, it  was held by the Farnese family and later passed to the Austrians. In 1815  Napoleon gave the city to his second consort, Marie-Louise. In 1861 it  became part of united Italy. It was badly damaged during World War II  but was rebuilt. It is the commercial centre of an agricultural region and  is famous for its Parmesan cheese. Sites of interest include the 12th-  century Romanesque cathedral, the 13th-century baptistery, and the uni�  versity (founded in the 11th century).</p><p>Parmenides \par- , men-9-,dez\ (b. c. 515 bc) Greek philosopher, leader  of the Eleatics. His general teaching has been reconstructed from the few  surviving fragments of his lengthy verse composition On Nature. He held  that the multiplicity of existing things, their changing forms and motion,  are but an appearance of a single eternal reality, �Being.� This doctrine,  which was formulated as the principle that �all is one,� entails that all  claims of change or of non-Being are illogical. Because of his method of  basing claims about appearances on a logical concept of Being, he is con�  sidered a founder of metaphysics. Plato�s dialogue Parmenides discusses  his thought.</p><p>Parmigianino \,par-mi-ja-'ne-no\ orig. Girolamo Francesco  Maria Mazzola (b. Jan. 11, 1503, Parma, Duchy of Milan�d. Aug.  24, 1540, Casalmaggiore, Cremona) Italian painter and etcher. He painted  some of his early frescoes for San Giovanni Evangelista; they were influ�  enced by Correggio, who had recently worked in the same church. His  originality is seen in his Self-Portrait in a Convex Mirror (1524). His  Madonna of the Long Neck (1534) is typical of his later work, which is  characterized by ambiguity of spatial composition, elongation of the  human figure, and the pursuit of a rhythmical, sensuous beauty beyond  nature. Among the most remarkable portrait painters of his age, he was  one of the first artists to develop the elegant and sophisticated version of  Mannerism that influenced the next generation of painters and was one of  the first Italian artists to practice etching.</p><p>Parnaiba \,par-na- , e-b3\ River River, northeastern Brazil. It rises in  the Tabatinga Mountains and flows northeast for 1,056 mi (1,700 km) to  empty into the Atlantic Ocean, forming a delta at its mouth. The river has  great economic importance. It is navigable by shallow-draft vessels from  its mouth at least as far south as the junction of the Caninde River. The  port of Parnaiba, located near the river�s mouth, is a commercial centre.</p><p>Parnassian \par-'na-se-9n\ Members of a French school of poetry of  the second half of the 19th century that was headed by Charles-Marie-  Rene Leconte de Lisle (1818-94) and Th�ophile Gautier. The Parnassians  stressed restraint, objectivity, technical perfection, and precise description  as a reaction against the emotionalism and verbal excess of Romanticism.  Their name came from the anthology to which they contributed, Le Par-  nasse contemporain (1866, 1871, 1876). Their influence was evident in  movements such as Modernismo and led to experimentation in metres and  verse forms and the revival of the sonnet.</p><p>Parnassus \par-'na-sos\, Mt. Mountain in central Greece. Located in  the Pindus range, it rises to a height of 8,061 ft (2,457 m). In the ancient  world it was sacred to Apollo and the Corycian nymphs, probably because</p><p>of its proximity to Delphi and its oracle. For Roman poets the Castalian  spring on Parnassus was a source of inspiration, and the mountain was  regarded as the home of the Muses.</p><p>Parnell \par-'nel\, Charles Stewart (b. June 27, 1846, Avondale,  County Wicklow, Ire.�d. Oct. 6, 1891, Brighton, Sussex, Eng.) Irish  nationalist leader. After an education at the University of Cambridge, he  returned to Ireland and served in the British Parliament (1875-91), intro�  ducing obstructionist legislative tactics to call attention to Ireland�s needs.  In 1877 he became president of the Home Rule Confederation. He was  jailed for making violent speeches against the new land act (1881-82),  then released to curb an increase in terrorist acts. Reaction against the  Phoenix Park murders enabled him to unite factions in Ireland to win sup�  port for parliamentary measures, such as William E. Gladstone�s Home Rule  proposals. He remained popular in Ireland until he was named in the  divorce suit of his mistress, Katherine O�Shea (1890).</p><p>parochial education Education offered institutionally by a religious  group. The curriculum usually includes both religious and general stud�  ies. In the U.S. and Canada, parochial education has referred primarily to  elementary and secondary schools maintained by Roman Catholic par�  ishes, but it can also apply to schools operated by Protestant, Jewish,  Muslim, and Buddhist organizations, among others.</p><p>parody In literature, a work in which the style of an author is closely  imitated for comic effect or in ridicule. Differing from both burlesque (by  the depth of its technical penetration) and travesty (which treats dignified  subjects in a trivial manner), parody mercilessly exposes the tricks of  manner and thought of its victim and therefore cannot be written without  a thorough appreciation of the work it ridicules. Examples date from as  early as ancient Greece and occur in nearly all literatures and all periods.</p><p>parole Supervised conditional liberty from prison granted prior to the  expiration of a prisoner�s sentence. Modern use of parole stems from a  change in penal philosophy to emphasize rehabilitation rather than retri�  bution. In some jurisdictions, those convicted of certain crimes (e.g., rape  or murder) are not eligible for parole. Conditions of parole vary, but in  all cases their violation may constitute grounds for reincarceration. Parole  supervision ranges from little more than a periodic police check to inten�  sive supervision by trained personnel. See also probation.</p><p>Parr, Catherine See Catherine Parr</p><p>Parra, Nicanor (b. Sept. 5, 1914, San Fabian, Chile) Chilean poet. A  student of mathematics and physics, Parra began teaching theoretical  physics at the University of Chile in 1952. One of the most important  Latin American poets of the 20th century, he is known for originating  so-called antipoetry (poetry that opposes traditional poetic techniques or  styles). In Poems and Antipoems (1954), he sought to make poetry acces�  sible to the masses by treating everyday problems of a grotesque world  in clear language with black humour and ironic vision. In later works he  experimented with language, and he continued to use antipoetic tech�  niques.</p><p>Parrhasius \po-'ra-zh3s\ or Parrhasios (fl. 5th century bc, Athens,  Greece) Greek painter. He was praised by ancient critics as a master of  outline drawing. He apparently succeeded in portraying various psycho�  logical states in his depictions of the face. Many of his drawings on wood  and parchment were preserved and highly valued by later painters for  purposes of study. His picture of Theseus adorned the Capitol in Rome;  other works were chiefly mythological groups. No works or copies sur�  vive.</p><p>Parrish \'par-ish\, (Frederick) Maxfield (b. July 25, 1870, Phila�  delphia, Pa., U.S.�d. March 10, 1966, Plainfield, N.H.) U.S. illustrator  and painter. Trained at the Pennsylvania Academy of the Fine Arts and  Drexel Institute of Art, he was the highest-paid commercial artist and  muralist in the U.S. by the 1920s. He is best known for his depictions of  fantasy landscapes populated by attractive young women. He used  meticulously defined outlines and intricately detailed natural back�  grounds; his unusual colours, especially the luminous �Parrish blue,� give  his pictures a dreamlike quality. Though his popularity declined in the  late 1930s, appreciation of his work revived in the 1960s and �70s.</p><p>parrot Any of the 333 species of birds in the family Psittacidae. About  220 species of true parrots (subfamily Psittacinae) are found worldwide  in warm regions (see parakeet). Many are brilliantly coloured.

The African gray parrot  (Psittacus erithacus ), intelligent and  a particularly good talker, is about 13  in. (33 cm) long and is gray except  for a red tail and white face; it lives  up to 80 years. The 31 species of  Amazon parrots (genus Amazona),  also good mimics, are 10-16 in.</p><p>(25-40 cm) long and predominantly  green. Four other subfamilies are  found chiefly around New Zealand  and Australia, as are the cockatoos  and cockatiel (family Cacatuidae); these are often considered parrots as  well because they are classified with Psittacidae in the order Psittaci-  formes. See also kea; lovebird; macaw.</p><p>parrot fish Any of about 80 species (family Scaridae) of slender, blunt�  headed, deep-bodied fishes found on  tropical reefs. They are often  brightly coloured and have large  scales. The fused teeth form a �beak�  used to scrape algae and the soft part  of coral from reefs. Platelike teeth in  the throat grind the ingested food and  bits of coral. Some species grow to  4 ft (1.2 m) long and weigh 45 lb (20  kg). The Indo-Pacific surf, or rivu-  lated, parrot fish ( Callyodon fascia-  tus) grows to 18 in. (46 cm) or more.</p><p>The queen parrot fish ( Scarus vetula)  is an Atlantic species.</p><p>parsec Unit of measure used by  astronomers to express distances to stars and galaxies. It is the distance  at which the radius of Earth�s orbit would subtend an angle of one sec�  ond of arc, so an object one parsec away would have a parallax of one  second. An object�s distance in parsecs is the reciprocal of its parallax in  seconds of arc. For example, Alpha Centauri, with a parallax of 0.76 sec�  ond, is 1.33 parsecs from the Sun and Earth. One parsec equals 3.26 light-  years, or 19.2 trillion mi (30.9 trillion km).</p><p>Parshvanatha Vparsh-vo-'na-toV (fl. 8th century bc) In Jainism, the 23rd  Tirthankara, or saint, of the present age. He founded a religious order and  formulated four vows binding on its members (not to kill, steal, lie, or  own property; a vow of celibacy was added later by Mahavira). Accord�  ing to legend, Parshvanatha once saved a family of serpents trapped in a  log in an ascetic�s fire. One of the snakes, later reborn as Dharana, the  lord of the underworld kingdom of nagas (snakes), sheltered Parshvanatha  from a storm sent by an enemy demon. In sculpture and painting Parsh�  vanatha is depicted with a canopy of snake hoods over his head.</p><p>Parsi or Parsee Zoroastrian of India. The Parsis, whose name means  �Persians,� are descended from Persian Zoroastrians who immigrated to  India to escape persecution by Muslims. The migration occurred sometime  between the 8th and 10th century. The Parsis settled in Gujarat and became  a farming community. When the British East India Co. took control of the  region around Bombay (now Mumbai) in the late 17th century and estab�  lished religious freedom, many Parsis moved there, and by the 19th century  they had become a wealthy merchant class. The Parsis still live chiefly in  the Mumbai area, though other Parsi communities exist in Bangalore,  India, and Karachi, Pakistan.

The compound  leaves are used in cooking. The family Apiaceae, sometimes called the  parsley family, contains 300-400 genera of plants found in a wide vari�  ety of habitats, mostly in northern temperate regions. Most are aromatic  herbs with feathery leaves. The flowers are often arranged in a conspicu�  ous umbel (a flat-topped cluster). Many species are poisonous, including  poison hemlock. Popular members of the family include carrot, celery,  parsnip, and fennel. Species used as herbs and spices include anise, dill,  coriander, caraway, and cumin ( Cuminum cyminum).</p><p>parsnip Plant (. Pastinaca sativa) of the parsley family, cultivated for its  large, tapering, fleshy, edible white  root, which has a distinctive, sweet  flavour and is usually served as a  cooked vegetable. At the end of sum�  mer the solids of the root consist  largely of starch, but a period of low  temperature changes much of the  starch to sugar. The root is hardy and  not damaged by hard freezing of the  soil. Native to Britain, Europe, and  temperate Asia, the parsnip has  become extensively naturalized in  North America.</p><p>Parsons, Sir Charles Alger�  non (b. June 13, 1854, London,</p><p>Eng.�d. Feb. 11, 1931, Kingston  Harbour, Jam.) British mechanical  engineer. He began work at the Arm�  strong engineering works in New�  castle upon Tyne in 1877 and formed  his own company to manufacture  turbines and other heavy machinery  in 1889. He developed the multiple-  stage turbine in 1884 and had intro�  duced it in power plants to generate electricity by 1891. Modern steam  and nuclear power plants still use turbines of this type to turn their gen�  erators. He demonstrated his marine turbine in Turbinia, a vessel that  attained a speed of over 34 knots in 1897; Parsons turbines made high�  speed ocean liners possible.</p><p>Parsons, Elsie Clews orig. Elsie Worthington Clews (b. Nov.  27, 1875, New York, N.Y., U.S.�d. Dec. 19, 1941, New York City) U.S.  sociologist, anthropologist, and folklorist. She was trained in sociology.  Her early works, advocating women�s rights, included The Family (1906)  and The Old-Fashioned Woman (1913). She later turned to anthropology  under the influence of Franz Boas and Alfred L. Kroeber. Her Pueblo Indian  Religion (1936) and Mitla (1936) remain standard studies of Pueblo and  Zapotec Indian cultures. She also produced notable collections of West  Indian and African American folklore.</p><p>Parsons, Talcott (b. Dec. 13, 1902, Colorado Springs, Colo., U.S.�d.  May 8, 1979, Munich, W.Ger.) U.S. sociologist. Parsons taught at Har�  vard University from 1927 to 1973. He advocated a structural-functional  analysis, a study of the ways that interrelated and interacting units form�  ing the structures of a social system contribute to the system�s develop�  ment and maintenance. He was largely responsible for introducing the  work of Emile Durkheim and Max Weber to American sociologists. His major  work is The Structure of Social Action (1937). See also functionalism.</p><p>Parson's Cause Dispute involving English clergy in colonial Virginia  over payment of salaries. When the British vetoed colonial laws that sub�  stituted currency for tobacco as payment for clerical salaries (1759), the  clergy sued for back pay. In the most publicized case (1763), Patrick Henry  defended a colonial parish against a suit by a clergyman, citing interfer�  ence by the British and convincing a jury to return only one penny in  damages. The clergy soon gave up their protest.</p><p>Part, Arvo (b. Sept. 11, 1935, Paide, Est.) Estonian composer. After  years of experimentation, he began in the late 1970s to produce his own  distinctive music. A devoutly Orthodox Christian, he developed a style  based on the slow modulation of sounds such as those produced by bells  and pure voice tones, a technique reminiscent of the medieval Notre-Dame  school and the sacred music of Eastern Orthodoxy. His major works  include the violin concerto Tabula Rasa (1977), Cantus in Memory of  Benjamin Britten (1977), Magnificat-Antiphones (1988), and The Beati�  tudes (1991).</p><p>Partch, Harry (b. June 24, 1901, Oakland, Calif., U.S.�d. Sept. 3,  1974, San Diego, Calif.) U.S. composer and instrument maker. He grew  up in Arizona and was largely self-taught musically. During the Great  Depression, he traveled as a hobo, conceiving many of his musical ideas  while doing so. About 1930 he began building original percussion and  string instruments, tunable to 43 divisions of the octave. His works often  involve theatrical elements, reflecting his interest in African, Japanese,  and Native American ritual.

The parterre grew out of the knot garden, a medieval form of bed in which  various plant types were separated from each other by hedges. In the 16th  century, the hedges were replaced by wooden or leaden shapes or by lines  of shells or coal, and the areas between were filled with colored sand or  stone chips. The naturalistic English garden of the 18th century displaced  the elaborate parterre.</p><p>Parthenon Vpar-tho-.nanV Chief temple of Athena on the Acropolis at  Athens. Built 447-432 bc by Ictinus and Callicrates under Pericles, it is  considered the culmination of the Doric order. Though the white marble  temple has suffered damage over the centuries, including the loss of most  of its sculpture, its basic structure remains intact. The colonnade supports  an entablature consisting of a plain architrave, a frieze of alternating tri�  glyphs (grooved blocks) and metopes (plain blocks with relief sculpture)  and, at the two ends, a triangular pediment. The colonnade consists of  eight columns on the ends and 17 on the sides, enclosing a cella; the inte�  rior originally held a great gold-and-ivory statue by Phidias. Such archi�  tectural devices as entasis of the columns and an upward curvature of the  base are used to correct optical illusions. Its sculpture rivaled its archi�  tecture. The pediment sculptures represent the birth of Athena and her  battle with Poseidon; a continuous frieze shows the annual Panathenaic  procession of citizens honoring Athena. The entire work is a marvel of  harmony and clarity.

Corresponding roughly to  modern northeastern Iran, it formed a province of the Persian Achaeme-  nian dynasty and later of the empire of Alexander the Great. After the dis�  solution of the Seleucid dynasty c. 250 bc, a new Parthian kingdom was  founded by Arsaces. The Arsacid dynasty ruled until it was overthrown by  the Sasanian dynasty c. ad 226. At its height in the early 1st century bc, it  was known as the Parthian empire and included the area between the  Euphrates and Indus rivers and between the Amu Darya and the Arabian  Sea. It was weakened by internal disorder and by conflict with Rome in  the 1st century bc. One of its later capitals was Hecatompylos. The ruins  of Ctesiphon, another major Parthian city, are in modem Iraq, near Bagh�  dad. The Parthians were famous as horsemen and archers.</p><p>Parti Quebecois \par-te-ka-be-'kwa\ Provincial Canadian political  party founded in 1968 by Rene Levesque and other French-Canadian sepa�  ratists in the province of Quebec. In the 1976 provincial election it won  a majority in the Quebec assembly, which then decreed French as the  province�s only official language of government and business. After a  separatist referendum on independence failed (1980), the party lost mem�  bership. The party revived in the 1990s, winning the provincial election  in 1994. In 1995 the party held another referendum on secession, which  was narrowly defeated.</p><p>partial derivative In differential calculus, the derivative of a function  of several variables with respect to change in just one of its variables. Par�  tial derivatives are useful in analyzing surfaces for maximum and minimum  points and give rise to partial differential equations. As with ordinary  derivatives, a first partial derivative represents a rate of change or a slope</p><p>of a tangent line. For a three-dimensional surface, two first partial deriva�  tives represent the slope in each of two perpendicular directions. Second,  third, and higher partial derivatives give more information about how the  function changes at any point.</p><p>partial differential equation In mathematics, an equation that con�  tains partial derivatives, expressing a process of change that depends on  more than one independent variable. It can be read as a statement about  how a process evolves without specifying the formula defining the pro�  cess. Given the initial state of the process (such as its size at time zero)  and a description of how it is changing (i.e., the partial differential equa�  tion), its defining formula can be found by various methods, most based  on integration. Important partial differential equations include the heat  equation, the wave equation, and Laplace's equation, which are central to  MATHEMATICAL PHYSICS.</p><p>particle accelerator Device that accelerates a beam of fast-moving,  electrically charged atoms (ions) or subatomic particles. Accelerators are  used to study the structure of atomic nuclei (see atom) and the nature of  subatomic particles and their fundamental interactions. At speeds close to  that of light, particles collide with and disrupt atomic nuclei and sub�  atomic particles, allowing physicists to study nuclear components and to  make new kinds of subatomic particles. The cyclotron accelerates posi�  tively charged particles, while the betatron accelerates negatively charged  electrons. Synchrotrons and linear accelerators are used either with posi�  tively charged particles or electrons. Accelerators are also used for radio�  isotope production, cancer therapy, biological sterilization, and one form  of radiocarbon dating.</p><p>particle physics or high-energy physics Study of the fundamen�  tal subatomic particles, including both matter (and antimatter) and the car�  rier particles of the fundamental interactions as described by quantum field  theory. Particle physics is concerned with structure and forces at this level  of existence and below. Fundamental particles possess properties such as  electric charge, spin, mass, magnetism, and other complex characteristics, but  are regarded as pointlike. All theories in particle physics involve quan�  tum mechanics, in which symmetry is of primary importance.

Gold and silver are often extracted together from  the same ores or recovered as by-products from the extraction of other  metals. A solid mixture of the two, known as bullion or dore, can be parted  by boiling in nitric acid. The silver is dissolved as silver nitrate, leaving a  gold residue that is filtered off and washed; silver is precipitated out of  solution by adding ferrous sulfate. This is the traditional method used in  assaying the content of gold and silver samples.</p><p>partnership Association of two or more persons or entities that con�  duct a business for profit as co-owners. Except in the case of the limited  liability partnership, which shares with the corporation the characteristic of  being treated as a single entity whose members have limited personal  liability, a partnership is traditionally viewed as an association of indi�  viduals rather than an entity with a separate and independent existence.  A partnership cannot exist beyond the lives of the partners. The partners  are taxed as individuals and are personally liable for torts and contrac�  tual obligations. Each is viewed as the agent of the others, and tradition�  ally all are jointly and severally liable for the tortious acts of any partner.</p><p>partridge Any of certain species of Old World game bird in the fam�  ily Phasianidae. The European gray partridge {Perdix perdix), introduced  into North America, has a reddish face and tail, gray breast, barred sides,  and a dark U shape on the belly. Males may be 12 in. (30 cm) long. The  hen lays about 15 eggs in a grassy cup in grainfields or hedges. Family  groups (coveys) forage for seeds and insects. The five Asian and 35 Afri�  can species of francolins (genus Francolinus ) have leg spurs and are  10�16 in. (25-40 cm) long. The snow partridge (Lerwa lerwa ) inhabits  high Asian mountains. Partridges are larger than quail and have a stron�  ger bill and feet. Grouse and bobwhites are often erroneously called par�  tridge.</p><p>parturition or birth or childbirth or labour or delivery Process  of bringing forth a child from the uterus, ending pregnancy. It has three  stages. In dilation, uterine contractions lasting about 40 seconds begin  20-30 minutes apart and progress to severe labour pains about every 3  minutes. The opening of the cervix widens as contractions push the fetus.  Dilation averages 13-14 hours in first-time mothers, less if a woman has</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1454 I Party of God &#x25BA; Pascin</p><p>had previous babies. When the cervix dilates fully, expulsion begins. The  �water� (amniotic sac) breaks (if it has not already), and the woman may  actively push. Expulsion lasts 1-2 hours or less. Normally, the baby�s  head emerges first; other positions make birth more difficult and risky. In  the third stage, the placenta is expelled, usually within 15 minutes. Within  six to eight weeks, the mother�s reproductive system returns to nearly the  prepregnancy state.

Single-party systems are found in  countries that do not allow genuine political conflict. Multiparty and two-  party systems represent means of organizing political conflict within plu�  ralistic societies and are thus indicative of democracy. Multiparty systems  allow for greater representation of minority viewpoints; since the coali�  tions that minority parties must often form with other minority parties to  achieve a governing majority are often fragile, such systems may be  marked by instability.

It was made available to the public in 1974 and was used by  many universities for the next 15 years. Pascal strongly influenced lan�  guages developed later, such as Ada. Complex data structures and algo�  rithms can be described concisely by Pascal, and its programs are easy to  read and debug.</p><p>pascal Unit of pressure, abbreviated Pa, in the International System of  Units. Named for Blaise Pascal, the unit is a pressure of one newton per  square meter (1 N/m 2 ). It is inconveniently small for many purposes, and  the kilopascal (kPa), 1,000 N/m 2 , is more commonly used in engineering  work (1 lb per sq in. equals 6.895 kPa).</p><p>Pascal \pas-'kal\, Blaise (b. June 19, 1623, Clermont-Ferrand,  France�d. Aug. 19, 1662, Paris) French mathematician, physicist, and  religious philosopher. The son of a mathematician, he was a child prodigy,  earning the envy of Rene Descartes with an essay he wrote on conic sec�  tions in 1640. In the 1640s and �50s he made contributions to physics  (formulating Pascal's law) and mathematics (working on the arithmetic  triangle, inventing a calculating machine, and contributing to the advance  of differential calculus). For work done in his early years, he is regarded  as the founder of the modern theory of probability. At the same time, he  became increasingly involved with Jansenism. Les Provinciales were a  series of letters defending Jansenism and attacking the Jesuits. His great  work of Christian apologetics, Apologie de la religion chretienne, was  never finished, but he put together most of his notes and fragments  between 1657 and 1658; these were published posthumously as Pensees  (1670). He returned to scientific work, contributing to the Elements de  geometrie and publishing his findings on cycloid curves, but he soon  returned to devotional life and spent his last years helping the poor. The  pascal was named in his honour. See also Pascal's wager.</p><p>Pascal's law or Pascal's principle In fluid mechanics, the statement  that in a fluid at rest in a closed container, a pressure change in one part  is transmitted without loss to every portion of the fluid and to the walls  of the container. The principle was first stated by Blaise Pascal, who also  discovered that the pressure at a point in a fluid at rest is the same in all  directions, and that the pressure would be the same on all planes passing  through a specific point.</p><p>Pascal's wager Practical argument for belief in God formulated by  Blaise Pascal. In his Pensees (1657-58), Pascal posed the following argu�  ment to show that belief in the Christian religion is rational: If the Chris�  tian God does not exist, the agnostic loses little by believing in him and  gains correspondingly little by not believing. If the Christian God does  exist, the agnostic gains eternal life by believing in him and loses an infi�  nite good by not believing. William James objected to the argument that it  supported belief in any religion that promised an eternal afterlife. Others  have objected that though the argument does give one a reason for believ�  ing in the Christian God, it does not make that belief �rational� in the  proper sense.</p><p>Paschal \pas-'kal\ II orig. Raniero (b. Bieda di Galeata, near  Ravenna�d. Jan. 21, 1118) Pope (1099-1118). He fostered the First Cru�  sade and favoured Gregorian reforms, but his pontificate was dominated  by the Investiture Controversy. Paschal came to terms on the issue of lay  investiture with Henry I of England and Philip I of France (1107). His  negotiations with Emperors Henry IV and Henry V were unsuccessful, and  he was imprisoned by Henry V (1111). While a prisoner, he agreed to  royal investiture of bishops and crowned Henry emperor, but a church  council declared his concessions invalid, and the archbishop of Vienne  excommunicated the emperor.</p><p>Pascin \pas-'ka n \, Jules orig.

The Pashtun, who num�  ber about 7.5 million in Afghanistan and 14 million in Pakistan, constitute  the majority of the population of Afghanistan. Their origins are unclear:  Pashtun tradition asserts that they are descended from Afghana, grandson  of King Saul of Israel, but most scholars believe that they arose from an  intermingling of ancient Aryans from the north or west with subsequent  invaders. Each Pashtun tribe is divided into clans, subclans, and patriar�  chal families. Disputes among the Pashtun over property, women, and  personal injury often result in blood feuds between families and whole  clans. Most tribal people are sedentary farmers; some are migratory herd�  ers and caravaners. Large numbers of the Pashtun have always been  attracted to military service.</p><p>Pasic Vpa-shet y ,\ English Vpa-shichX, Nikola (b. Dec. 31, 1845, Zaje-  car, Serbia�d.

The editor of a socialist  newspaper in Serbia, he was elected  in 1878 to the legislature, where he  opposed the authoritarian monarchy  and advocated a parliamentary  democracy. In 1881 he helped found  the Radical Party, but he was forced  to flee to Bulgaria in 1883. Returning  to Serbia in 1889 under a new king,  he served as premier (1891-92) and  as ambassador to Russia (1893-94).</p><p>Forced into exile again because of his  political radicalism (1899-1903), he  returned to support the Karadjordjevic  dynasty and King Peter I. As leader of  the Radical Party, he served as pre�  mier of Serbia during most of the period (1904-18), then helped create the  new Kingdom of Serbs, Croats, and Slovenes (later Yugoslavia). As premier  (1921-26), he pushed for a unitary constitution that confirmed Serbia�s  dominance despite opposition from the historically separate regions.</p><p>Pasionaria, La See Dolores Ibarruri</p><p>Pasolini X.pa-so-'le-neV, Pier Paolo (b. March 5, 1922, Bologna,  Italy�d. Nov. 2, 1975, Ostia, near Rome) Italian film director, poet, and  novelist. He wrote novels about Rome�s slum life as well as a significant  body of poetry. Pasolini became a screenwriter in the mid-1950s, collabo�  rating most notably on Federico Fellini�s Nights of Cabiria (1956). His  directorial debut, Accattone (1961), was based on his novel A Violent Life  (1959). His best-known film, stylistically unorthodox and implicitly radi�  cal, is perhaps The Gospel According to Saint Matthew (1964). Later films  include Oedipus Rex (1967), Teorema (1968), Medea (1969), The Can�  terbury Tales (1972), and The Arabian Nights (1974), which won a spe�  cial jury prize at Cannes. His use of eroticism, violence, and depravity  were criticized by Italian religious authorities.</p><p>pasqueflower See anemone</p><p>passage, rite of Any of numerous ceremonial events, existing in all  societies, that mark the passage of an individual from one social or reli�  gious status to another. The term was coined by the French anthropolo�  gist Arnold van Gennep (1873-1957) in 1909. Many of the most important  rites are connected with the biological stages of life�birth, maturity,  reproduction, and death. Other rites celebrate changes that are wholly  cultural, such as initiation into special societies. In modem societies,  graduation from school is a rite of passage. Scholars often interpret rites  of passage as mechanisms by which society confronts and incorporates  change without disrupting the equilibrium necessary to social order.

Passenger pigeons  were about 13 in. (32 cm) long and  had a long pointed tail; the male was  pinkish, with a blue-gray head. Bil�  lions inhabited eastern North  America in the early 19th century;  migrating flocks darkened the skies  for days at a time. Gunners began to  slaughter them in huge numbers for  shipping by railway carloads for sale  in city meat markets. Martha, the last  known passenger pigeon, died in  1914 in the Cincinnati Zoo. The  bird�s extinction was largely respon�  sible for ending the marketing of  game birds and gave major impetus  to the conservation movement.</p><p>passerine Any perching bird. All  passerines belong to the largest order  of birds, Passeriformes, and have  feet specialized for holding onto a horizontal branch (perching). The pas�  serine foot has three forward-directed toes and one backward-directed toe.  Most passerines have moderately curved, sharp claws. Some ground�  dwelling species (e.g., larks, pipits) have flatter, longer feet. Species that  spend much time airborne (e.g., swallows) have small, weak feet. Species  that cling and climb (e.g., nuthatches) have strong, sharp, curved claws.  Passerines include about 4,000 species of oscines (songbirds; suborder  Passere, or Oscines) and 1,100 species of suboscines (suborders Eury-  laimi, called broadbills; Tyranni, including flycatchers; and Menurae,  including lyrebirds). Suboscines lack the syrinx of the songbirds or have  only a poorly developed one, but some can utter complex vocalizations.  All passerines are land birds, abundant worldwide except in Antarctica.  Most are insectivorous, solitary nesters that build a cup-shaped open nest.</p><p>Passion Musical setting of the suffering and crucifixion of Christ. The  early Passion consisted entirely of plainchant. Liturgical enactments of  Christ�s Passion date from the early Middle Ages, the characters� parts  being sung by individual celebrants and the crowd�s role by the congre�  gation. Polyphonic Passions began appearing in the 15th century. In the  German tradition exemplified by Heinrich Schutz, the Passion closely  resembles the dramatic oratorio, with solo arias and other ensembles  contrasting with choral sections; the alternative MOTET-style Passion lacked  solo sections and avoided dramatic oppositions. After the 18th century,  Passions ceased to be widely composed.</p><p>Passion play Religious drama of medieval origin dealing with the suf�  fering, death, and resurrection of Jesus. Early Passion plays were written  in Latin and consisted of Gospel readings alternating with poetic descrip�  tions of the events of Christ�s Passion (i.e., his sufferings between the  Last Supper and his death). Use of the vernacular for these poetic pas�  sages led to the development of independent vernacular plays. By the 16th  century many of the plays had been overtaken by secular influences and  had become mere popular entertainments. Some survived into the 21st  century, most notably the one performed by local villagers every 10 years  at Oberammergau, Ger.

Members of this family grow mostly in warm regions. Many species  produce edible fruits. Members of the largest genus, Passiflora, are highly  prized for their showy, unusual flowers. A pedestal-like structure in the  centre of the flower carries the reproductive parts of both sexes. The pas�  sionflower blossom is often used to symbolize events in the last hours  (Passion) of Jesus, which accounts for the name of the group.</p><p>passive resistance See civil disobedience, satyagraha</p><p>Passover In Judaism, the holiday commemorating the liberation of the  Hebrews from slavery in Egypt.

Pasta is traditionally associated with Italian cuisine, though it may  have entered Europe from Asia during the Mongol invasions of the 13th  century. In making pasta, semolina dough is rolled out and sliced or com�  pacted and forced through perforated plates (dies) that form it into the  desired shape. It is produced in the form of sheets, ribbons, cords, tubes,  and other shapes, each with its own name (e.g., spaghetti, macaroni). The  formed dough is then dried under controlled conditions. Pasta is boiled  and topped with a sauce or combined with other foods before serving.</p><p>pastel Drawing medium consisting of fragile, finger-size crayons called  pastels, made of powdered pigments combined with a minimum of non-  greasy binder (usually gum tragacanth or, from the mid-20th century,  methyl cellulose). Because pigment applied with pastel does not change  in colour value, the final effect can be seen immediately. Pastel remains  on the surface of the paper and thus can be easily obliterated unless pro�  tected by glass or a fixative spray of glue size or gum solution. When  pastel is applied in short strokes or linearly, it is usually classed as draw�  ing; when it is rubbed, smeared, and blended to achieve painterly effects,  it is often regarded as a painting medium.</p><p>Pasternak, Boris (Leonidovich) (b. Feb. 10, 1890, Moscow,  Russia�d. May 30, 1960, Peredelkino, near Moscow) Russian poet and  prose writer. He studied music and philosophy and after the Russian Revo�  lution of 1917 worked in the library of the Soviet commissariat of educa�  tion. His early poetry, though avant-garde, was successful, but in the 1930s  a gap widened between his work and officially approved literary modes,  and he supported himself by doing translations. The novel Doctor Zhivago  (1957; film, 1965), an epic of wandering, spiritual isolation, and love amid  the harshness of the revolution and its aftermath, was a best-seller in the  West but until 1987 circulated only in secrecy in the Soviet Union. Paster�  nak was awarded the Nobel Prize for Literature in 1958, but he was forced  to decline it because of Soviet opposition to his work.</p><p>Pasteur \pas-'t9r\, Louis (b. Dec. 27, 1822, Dole, France�d. Sept. 28,  1895, Saint-Cloud, near Paris) French chemist and microbiologist. Early  in his career, after studies at the Ecole Normale Superieure, he researched  the effects of polarized light on chemical compounds. In 1857 he became  director of scientific studies at the Ecole. His studies of fermentation of  alcohol and milk (souring) showed that yeast could reproduce without free  oxygen (the Pasteur effect); he deduced that fermentation and food spoil�  age were due to the activity of microorganisms and could be prevented  by excluding or destroying them. His work overturned the concept of  spontaneous generation (life arising from nonliving matter) and led to heat  pasteurization, allowing vinegar, wine, and beer to be produced and trans�  ported without spoiling. He saved the French silk industry by his work  on silkworm diseases. In 1881 he perfected a way to isolate and weaken  germs, and he went on to develop vaccines against anthrax in sheep and  cholera in chickens, following Edward Jenner�s example. He turned his  attention to researching rabies, and in 1885 his inoculating with a weak�  ened virus saved the life of a boy bitten by a rabid dog. In 1888 he founded  the Pasteur Institute for rabies research, prevention, and treatment.</p><p>Pasteurella X.pas-chs-'rel-oV Genus (named after Louis Pasteur) of rod�  shaped bacteria that cause several serious diseases in domestic animals and  milder infections in humans. Members are gram-negative (see gram stain),  do not move, and do not require oxygen. The widespread infections they  cause, referred to by the general term pasteurelloses, are transmitted by  direct contact and, in some cases, by ticks and fleas. Control by vaccine is  variable, as is treatment with penicillin and other antibiotics.</p><p>pasteurization Partial sterilization of a substance, especially milk or  other beverages, by using heat to destroy microorganisms while leaving  its chemical makeup unaltered. The process is named for Louis Pasteur, its</p><p>originator. Pasteurization of milk requires temperatures of about 145 �F  (63 �C) for about 30 minutes, or higher temperatures for shorter periods.  The treatment destroys any disease-causing organisms (principally Myco�  bacterium tuberculosis ) as well as organisms that cause spoilage.

Virgil�s Eclogues were influential as  well, as was Edmund Spenser�s Shepheardes Calender in the Renaissance.

Accusing the nobles,  clergy, and bourgeoisie of indifference to the king�s fate, they began pil�  laging churches and towns and attacking clerics, the rich, and Jews. The  second Pastoureaux converged on Paris in 1320 to punish Philip V for  failing to undertake a Crusade he had called.

Pasupata teachings were believed to have originated  with Shiva himself, reincarnated as the teacher Lakulin. The sect�s rise is  dated roughly between the 2nd century bc and the 2nd century ad. The  ascetic practices adopted by the Pasupatas included smearing their bod�  ies thrice-daily with ashes. Out of Pasupata doctrine developed two  extreme schools, Kapauka and Kalamukha, as well as one moderate sect,  Shaivism.</p><p>Patagonia Semiarid scrub plateau, southern Argentina.

Educated in India, he set up his own law office in  1900 and later studied law in Britain; he did not become involved in poli�  tics until 1917. Like Mohandas K. Gandhi (and unlike Jawaharlal Nehru),  he advocated dominion status within the British Commonwealth rather  than independence for India. He opposed armed struggle on practical  rather than moral grounds, and he was not interested in Hindu-Muslim  unity. Patel was repeatedly a candidate for the presidency of the Indian  National Congress, but his uncompromising attitude toward the Indian  Muslims cost him Gandhi�s support and, ultimately, the presidency. After  Indian independence (1947), he held several cabinet positions. He is  remembered for achieving the peaceful integration of the princely Indian  states into the Indian union and the political unification of India.</p><p>Patenier, Joachim de See Joachim Patinir</p><p>patent Government grant to an inventor of the exclusive right to make,  use, or sell an invention, usually for a specified term. It may be granted  for a process or method that is new, useful, and not obvious, or for a new  use of a known process, machine, or composition of matter or material,  including asexually reproduced plants and genetically engineered organ�  isms. It may also be granted for any new, original, and ornamental design  for an article of manufacture. The first recorded patent for an industrial  invention was granted in 1421 in Florence to the architect and engineer  Filippo Brunelleschi. Until recently there were wide variations in the patent  systems implemented by different countries. The duration of patents rec�  ognized generally ranged from 16 to 20 years. In some countries (e.g.,  France), some patents were given shorter terms because the inventions  had an overall general usefulness. In communist countries (e.g., the Soviet  Union), patents per se were not recognized; instead, certificates were  issued to inventors to ensure that they received some form of compensa�  tion for their work. The agreement establishing the World Trade Organi�  zation in the 1990s specifies a minimum set of exclusive rights that all  patentees must be accorded and mandates a minimum patent term of 20  years from the date an application is filed. Patents are considered personal  property and may be sold, assigned, or otherwise transferred.</p><p>Pater Vpa-torV, Walter (Horatio) (b. Aug. 4, 1839, Shadwell, Lon�  don, Eng.�d.

Elected a fellow at the University of Oxford in 1864,  Pater made his reputation as a scholar and aesthete with essays collected  in Studies in the History of the Renaissance (1873). Written in a delicate,  fastidious style, the essays introduced his influential advocacy of �art for  art�s sake,� which contrasted with the prevailing emphasis on art�s moral  or educational values and became a cardinal doctrine of Aestheticism. Mar�  ius the Epicurean (1885), a philosophical romance on the ideal life, is his  most substantial work.</p><p>Paterson City (pop., 2000: 149,222), northeastern New Jersey, U.S. It  is located on the Passaic River, north of Newark, N.J.

The successful enterprise, begun by Alexander Hamil�  ton, was known as the Society for Establishing Useful Manufactures. In  the 19th century it was a centre of cotton textile production, the silk  industry, and locomotive manufacturing. It received a city charter in 1851  and was the scene of many labour disputes.

At the Constitutional Convention he played a leading  role in the opposition of the small states to representation according to  population in the federal legislature, submitting the New Jersey (or small-  state) Plan, which called for an equal vote for all states, to counter the  Virginia (or large-state) Plan, which favoured larger states. He secured  ratification of the Constitution of the United States in New Jersey and was  elected one of the state�s first U.S. senators (1789-90).

In 1909 Pathe produced his first �long film,� Les Mis-  erables, a four-reel screen version of the novel by Victor Hugo, and  launched the Pathe Gazette , an internationally popular newsreel that ran  until 1956. In 1914 Pathe Freres released the first episodes of The Perils  of Pauline, one of the earliest screen serials. With facilities throughout the  world, Pathe Freres dominated the film market in the early 20th century,  and it remained a film distributor after Charles�s retirement in 1929.</p><p>pathology Medical specialty dealing with causes of disease and struc�  tural and functional changes in abnormal conditions. As autopsies, initially  prohibited for religious reasons, became more accepted in the late Middle  Ages, people learned more about the causes of death. In 1761 Giovanni  Battista Morgagni (1682-1771) published the first book to locate disease  in individual organs. In the mid-19th century the humoral theories of  infection were replaced first by cell-based theories (see Rudolf Virchow)  and then by the bacteriologic theories of Robert Koch and Louis Pasteur.  Today pathologists work mostly in the laboratory and consult with a  patient�s physician after examining specimens including surgically  removed body parts, blood and other fluids, urine, feces, and discharges.  Culturing of infectious organisms, staining, fibre-optic endoscopy, and  electron microscopy have greatly expanded the information available to  the pathologist.</p><p>patina See desert varnish</p><p>Patinir X.pa-to-'nhA, Joachim (de) or Joachim de Patinier or  Joachim de Patenier \,pa-t9-'ner\ (b. c. 1485, Bouvignes, Namur�d.  Oct. 5, 1524, Antwerp) Netherlandish painter. Nothing is known of his  early life, but his work reflects knowledge of the paintings of Gerard  David. He is the first Western artist known to have specialized in land�  scape painting, though his work has a nominal religious subject and he  never painted pure landscapes. His novelty lay in the fact that the reli�  gious motif in such works as Flight into Egypt (1515-20) was overshad�  owed by the phenomena of the natural world. He apparently made a  practice of supplying landscape settings for figure compositions painted  by other Flemish masters. His landscapes combine realistic detail with a  sense of fantasy that suggests his familiarity with the works of Hierony�  mus Bosch.</p><p>patio In Spanish and Latin American architecture, a courtyard open to  the sky within a building. A Spanish development of the Roman atrium, it  is comparable to the Italian cortile but provides more seclusion, possibly  due to Moorish custom.

The ore was crushed  and ground by mule power in arrastras, reducing it to a fine mud. This  was then spread over a courtyard or patio, sprinkled with mercury, salt,  and copper sulfate, and mixed by driving mules over it. Chemical reac�  tions caused the silver to dissolve in the mercury. When the amalgam�  ation was complete, the material was agitated with water in large tubs and  the mud run off. The amalgam at the bottom was collected and heated to  drive off the mercury. Used for much of the world�s silver production for  350 years, the process was replaced by the cyanide process early in the  20th century.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1458 I Patna &#x25BA; Paul III</p><p>Patna Vpot-noV City (pop., 2001 prelim.: 1,376,950), capital of Bihar  state, northeastern India, on the Ganges River.

They  attempted to hold on to magistracies, priesthoods, and legal and religious  knowledge, and the great civil struggle of the Roman republic was the effort  of the plebeians to achieve equality and break the patrician monopoly.  Gradually the patricians lost their monopoly�except in a few areas, such  as selected priesthoods and the office of interrex�and in the late repub�  lic (1st century bc) the distinction lost political importance.

Ordained a priest in 1519, he was unanimously  elected pope in 1534. Though loose in morals in earlier years (he had  three sons and a daughter), he became an efficient promoter of reform,  convening the Council of Trent in 1545 and initiating the Counter-  Reformation.

He was a church dip�  lomat for much of his career, until he was named archbishop of Milan in  1954. He became a cardinal in 1958, and in 1963 he was elected pope.  Paul VI presided over the final sessions of the Second Vatican Council  and appointed commissions to carry out its reforms, including revisions  in the mass. He also relaxed rules on fasting, removed a number of ques�  tionable saints from the church�s calendar, and enforced conservative  positions on birth control and clerical celibacy.

Saul (b. ad 10?, Tarsus in Cilicia�d. 67?, Rome)  Early Christian missionary and theologian, known as the Apostle to the  Gentiles. Born a Jew in Tarsus, Asia Minor, he was trained as a rabbi but  earned his living as a tentmaker. A zealous Pharisee, he persecuted the first  Christians until a vision of Jesus, experienced while on the road to Dam�  ascus, converted him to Christianity. Three years later he met St. Peter  and Jesus� brother James and was henceforth recognized as the 13th  Apostle. From his base in Antioch, he traveled widely, preaching to the  Gentiles. By asserting that non-Jewish disciples of Christ did not have to  observe Jewish law, he helped to establish Christianity as a separate reli�  gion rather than a Jewish sect. On a journey to Jerusalem, he aroused such  hostility among the Jews that a mob gathered, and he was arrested and  imprisoned for two years. The circumstances of his death are unknown.  Paul�s ministry and religious views are known largely from his letters, or  epistles, collected in the New Testament, which are the first Christian theo�  logical writing and the source of much Christian doctrine.

He  taught physics in Zurich (1928-40) and later at the Institute for Advanced  Study in Princeton, N.J. In 1924 he proposed that a spin quantum num�  ber, +Vi or -Vi, is necessary to specify electron energy states. In 1930 he  proposed that the energy and momentum apparently lost when an elec�  tron is emitted from an atomic nucleus in beta decay is carried away by  an almost massless, uncharged, and difficult-to-detect particle (the neu�  trino). He was awarded a 1945 Nobel Prize for his 1925 discovery of the  Pauli exclusion principle.</p><p>Pauli exclusion principle Assertion proposed by Wolfgang Pauli  that no two electrons in an atom can be in the same state or configuration  at the same time. It accounts for the observed patterns of light emission  from atoms. The principle has since been generalized to include the whole  class of particles called fermions. The spin of such particles is always an  odd whole-number multiple of Vi. For example, electrons have spin Vi,  and can occupy two distinct states with opposite spin directions. The Pauli  exclusion principle indicates, therefore, that only two electrons are  allowed in each atomic energy state, leading to the successive buildup of  orbitals around the nucleus. This prevents matter from collapsing to an  extremely dense state.</p><p>Pauling, Linus (Carl) (b. Feb. 28, 1901, Portland, Ore., U.S.�d. Aug.  19, 1994, Big Sur, Calif.) U.S. chemist.

He  regained the presidency in 1985 and instituted a program of economic  austerity that reduced the hyperinflation that had imperiled the Bolivian  economy.</p><p>Pazzi conspiracy Vpat-se\ (April 16, 1478) Unsuccessful plot to over�  throw the Medici rulers of Florence. It was led by the rival Pazzi family,  with the backing of Pope Sixtus IV, who wanted to consolidate papal rule  over northern central Italy. The conspirators tried to assassinate two Med�  ici brothers during mass at the Cathedral of Florence; they killed Giuliano  de� Medici, but Lorenzo de� Medici escaped. The people of Florence ral�  lied to the Medici and killed many of the conspirators, leaving Lorenzo  more powerful than before and setting off a two-year war with the papacy.</p><p>PBS in full Public Broadcasting Service Private, nonprofit U.S.  corporation of public television stations. PBS provides its member sta�  tions, which are supported by public funds and private contributions rather  than by commercials, with educational, cultural, news, and children�s  programs that are produced by its members and by independent produc�  ers worldwide. Its popular programs have included Sesame Street, Mas�  terpiece Theatre, Great Performances, NewsHour with Jim Lehrer, and  Nova. PBS was founded in 1969 to coordinate and provide services to its  member stations, which now number about 350. Funding is provided  mainly by viewers� contributions, state governments, and grants from  businesses and private foundations; the U.S. government, through the  Corporation for Public Broadcasting, supplies about 15%.</p><p>PC See PERSONAL COMPUTER</p><p>PCB in full polychlorinated biphenyl \bl-'fe-n 3 l, bi-'fe-n 3 l\ Any of  a class of highly stable organic compounds prepared by the reaction of  CHLORINE with biphenyl, a two-ring compound. The commercial product,  a mix of several PCB isomers, is a colourless, viscous liquid that is almost  insoluble in water, does not degrade under high temperatures, and is a  good electrical insulator (see dielectric). PCBs became widely used as  lubricants, heat-transfer fluids, and fire-resistant dielectric fluids in trans�  formers and capacitors in the 1930s and �40s. In the mid 1970s they were  found to cause liver dysfunction in humans and came under suspicion as  carcinogens; their manufacture and use were consequently restricted in  the U.S. and many other countries, though illegal dumping by manufac�  turers continued. They persist in the environment and have entered the  food chain, causing great harm especially to invertebrates and fish.</p><p>pea Any of several species, comprising hundreds of varieties, of herba�  ceous annual plants belonging to the  family Leguminosae (or Fabaceae,  also known as the pea family; see  legume), grown virtually worldwide  for their edible seeds. Pisum sativum  is the common garden pea of the  Western world, which Gregor Men�  del used for his pioneering studies of  heredity. While their origins have not  been definitely determined, it is  known that peas are one of the old�  est cultivated crops. Some varieties,  called sugar peas, snow peas, or  mange-touts, have edible pods and  are popular in East Asian cuisines.</p><p>See also sweet pea.</p><p>Peabody Vpe-bo-deX, Elizabeth  (Palmer) (b. May 16, 1804, Billerica, Mass., U.S.�d. Jan. 3, 1894,  Jamaica Plain, Mass.) U.S. educator and leader in the kindergarten move�  ment in America. She served as secretary to William Ellery Channing  (1825-34) and worked with Bronson Alcott in his Temple School. She  opened a Boston bookshop in 1839, which became a centre for Transcen-  dentalist activities. She published works by Margaret Fuller and Nathaniel  Hawthorne and also published and wrote articles for The Dial. Inspired  by the work of Friedrich Froebel, she opened the first English-language kin�  dergarten in the U.S. in 1860 and thereafter devoted herself to organiz�  ing public and private kindergartens. Her sisters married Horace Mann  and Nathaniel Hawthorne.</p><p>Peabody Vpe-.ba-deX, George (b. Feb. 18, 1795, South Danvers [now  Peabody], Mass., U.S.�d. Nov. 4, 1869, London, Eng.) U.S. merchant  and financier. Born in South Danvers, Mass, (renamed Peabody in his  honour), he earned an early fortune as a partner in a wholesale dry-goods  business and as president of the Eastern Railroad (from 1836). On a trip  to England, he negotiated an $8 million loan for the near-bankrupt state  of Maryland. In 1837 he moved to London permanently and founded a  merchant banking house specializing in foreign exchange; his banking  operations helped establish U.S. credit abroad. He spent most of his for�  tune on philanthropy to promote education and the arts; his gifts include  a natural history museum at Yale University, an archaeology museum at  Harvard University, and an Asian export art museum in Salem, Mass.</p><p>Peace Corps U.S. government agency of volunteers, formed in 1961  by Pres. John F. Kennedy. Its purpose is to assist other countries in their  development efforts by providing skilled workers in the fields of educa�  tion, agriculture, health, trade, technology, and community development.  Volunteers are expected to serve for two years as good neighbours in the  host country, to speak its language, and to live on a level comparable to  that of the local residents. By the early 21st century, more than 165,000  volunteers had served in the corps.</p><p>Peace of God Movement within the medieval Roman Catholic church  in response to the breakdown of public order. The movement began at a  council at Le Puy in 975, but other, more important councils occured in  southern and central France in the late 10th and early 11th centuries.  Regional lay and religious authorities attended the councils to ensure  God�s peace, and they were often joined by large crowds who came to  venerate the relics displayed at the meetings. The peace decrees forbade,  under pain of excommunication, private warfare or violence against  churches, clerics, pilgrims, merchants, women, peasants, and cattle. Par�  ticipants at the councils took oaths on sacred relics to uphold the deci�  sions made at those councils. The peace was also decreed at the councils  of Charoux (c. 989), Limoges (994 and 1031), Poitiers (c. 1000), and  Bourges (1038).</p><p>peace pipe See calumet</p><p>Peace River River, western Canada. Formed by the confluence of the  Finlay and Parsnip rivers in the Canadian Rockies of British Columbia,  it flows east across the border of Alberta to join the Slave River just north  of its outlet from Lake Athabasca. It is 1,195 mi (1,923 km) long. It was  explored by Alexander Mackenzie in 1792-93 and became a major fur�  trading route. It is an important source of hydroelectric power.</p><p>Peace River River, west-central Florida, U.S. It rises in Polk county  and flows south and southwest into Charlotte Harbor on the southwest�  ern coast. It is about 85 mi (135 km) long.</p><p>peach Small to medium-sized fruit tree ( Prunus persica) of the rose  family, grown throughout the  warmer temperate regions of both  hemispheres, and the fruit it pro�  duces. It probably originated in  China and spread westward. Peach  trees are intolerant of severe cold but  require winter chilling to induce  spring growth. The long, pointed  leaves are glossy green and lance�  shaped. Pink or white flowers grow  singly or clustered. The fleshy, juicy  exterior of the fruit is edible; the hard  interior is called the stone or pit. In  freestone types, stones separate eas�  ily from ripe flesh; in clingstone  types, the flesh adheres firmly to the  stone. Thousands of varieties have  been developed. Peach skin is downy  or fuzzy; smooth-skinned peaches are nectarines. Peaches are widely eaten  fresh and are baked in desserts. Canned peaches are a staple commodity  in many regions. Related plants include almond, plum, and cherry.</p><p>peacock Any of three species (family Phasianidae) of resplendent birds  of open lowland forests. Blue, or Indian (Pavo cristatus), and green, or  Javanese (P. muticus), peacock males are 35-50 in. (90-130 cm) long and  have a 60-in.

The blue and green male  Congo peacock {Afropavo congensis ) has a short rounded tail; the reddish  and brown hen has a topknot.</p><p>Peacock, Thomas Love (b. Oct. 18, 1785, Weymouth, Dorset,  Eng.�d. Jan. 23, 1866, Lower Halliford, Middlesex) English novelist and  poet. For most of his life Peacock worked for the East India Co. He was  a close friend of Percy B. Shelley, who greatly inspired his writing. His  best verse is interspersed in his novels, which are dominated by the con�  versations of their characters and satirize the intellectual currents of the  day. His best-known work, Nightmare Abbey (1818), satirizes romantic  melancholy and includes characters based on Shelley, Samuel Taylor Col�  eridge, and Lord Byron.</p><p>Peale, Charles Willson (b. April 15, 1741, Queen Anne's county,  Md.�d. Feb. 22, 1827, Philadelphia, Pa., U.S.) U.S. painter, inventor, and  naturalist. He began his career by exchanging a saddle for painting les�  sons. He later went to London to study with Benjamin West. On his return  he became the preeminent portrait painter of the middle colonies. He  damaged his professional career by entering enthusiastically into the revo�  lutionary movement. In 1786 he founded an institution in Philadelphia for  the study of natural law and display of natural history and technological  objects; the Peale Museum, the first major U.S. museum, was widely imi�  tated by other museums of the period and later by P.T. Barnum. Peale is  best remembered for his portraits of the leading figures of the American  Revolution.</p><p>Peale, Norman Vincent (b. May 31, 1898, Bowersville, Ohio,  U.S.�d. Dec. 24, 1993, Pawling, N.Y.) U.S. Protestant clergyman. The  son of a Methodist preacher, he attended Ohio Wesleyan University and  was ordained a pastor in the Methodist Episcopal church. After leading  congregations in Brooklyn and Syracuse, N.Y., in 1933 he became pastor  of Marble Collegiate Church in New York City, where he remained for  the rest of his career. In 1937 he cofounded the Religio-Psychiatric Clinic,  which combined religion and psychiatry in the interests of mental health.  He gained fame through radio and television sermons and through his  books, including the best-selling Power of Positive Thinking (1952). In  1969 he was elected president of the Reformed Church in America.</p><p>Peale, Rembrandt (b. Feb. 22, 1778, Bucks county, Pennsylvania,  U.S.�d. Oct. 3, 1860, Philadelphia, Penn.) U.S. painter and writer. A son  of Charles Willson Peale, he studied with his father at the Royal Academy  in London. In Paris 1808-10 he was offered the post of court painter to  Napoleon I. His early portrait of Thomas Jefferson (1805) was his master�  piece. Following his father�s example, he opened a museum and portrait  gallery in Baltimore, where he established the first illuminating gasworks.  When he resumed painting, he turned to formal subject pieces (e.g., The  Court of Death, 1820) before returning to portraiture, continuing a series  of portraits of George Washington.</p><p>peanut or groundnut Annual legume ( Arachis hypogaea) and its  edible seeds, which have the peculiar habit of ripening underground in  pods. Native to tropical South America, peanuts were introduced early  into the Old World tropics. Each pod contains one to three oblong seeds  with whitish to dark-purple seed coats. Pound for pound, peanuts have  more protein, minerals, and vitamins than beef liver, more fat than heavy  cream, and more calories than sugar. They are pressed for edible oil,  ground into peanut butter, eaten as snacks, and used in cooking. The plant  is fed to livestock.</p><p>pear Any of several species of trees  of the genus Pyrus, especially P  communis, of the rose family, which  is one of the most important fruit  trees in the world and is cultivated in  all temperate-zone countries of both  hemispheres. The thousands of vari�  eties include Bartlett (by far the most  widely grown), Beurre Bose, and  Beurre d'Anjou. In the U.S., much of  the crop is canned; in Europe, pears  are more commonly eaten fresh or  used for perry (fermented pear  juice). The tree is taller and more</p><p>upright than the apple tree; pear fruits are sweeter and softer than apples.  Hard cells (grit, or stone cells) dot the flesh.</p><p>pearl Concretion formed by a mollusk and consisting of the same mate�  rial (called nacre, or mother-of-  pearl) as the mollusk's shell. Long  treasured as gemstones, pearls are  valued for their translucence and lus�  tre and for the delicate play of sur�  face colour. The more perfect a  pearl�s shape and the deeper its lus�  tre, the greater its value. The colour  varies with the mollusk and its envi�  ronment. Jewelers of the 16th�17th  centuries often used irregularly  shaped (baroque) pearls, formed  from muscular tissue, to form the  bodies of animals and other figures.</p><p>In Europe and China, mother-of-  pearl has been used as an inlay mate�  rial for decorating furniture. The  discovery that a pearl could be cul�  tivated by insertion of a foreign  object inside the mollusk�s shell is  said to have been made in 13th-  century China.</p><p>Pearl Harbor Inlet, southern coast of Oahu island, Hawaii, U.S. It lies  6 mi (10 km) west of Honolulu, forming a landlocked harbour connected  with the Pacific Ocean. In 1887 Hawaii granted the U.S. the exclusive use  of the harbour as a coaling and repair station, and in 1908 a naval station  was established. In 1941 the harbour was attacked without warning by the  Japanese air force, causing great loss of life and precipitating U.S. entry  into World War II. It is now the headquarters of the U.S. Pacific Fleet.</p><p>Pearl Harbor attack (Dec. 7, 1941) Surprise aerial attack by the  Japanese on the U.S. naval base at Pearl Harbor on Oahu island, Hawaii,  that precipitated U.S. entry into World War II. In the decade preceding  the attack, U.S.-Japanese relations steadily worsened, especially after  Japan entered into an alliance with the Axis powers (Germany and Italy)  in 1940, and by late 1941 the U.S. had severed practically all commer�  cial and financial relations with Japan. On November 26 a Japanese fleet  sailed to a point some 275 mi (440 km) north of Hawaii, and from there  about 360 planes were launched. The first dive-bomber appeared over  Pearl Harbor at 7:55 am (local time) and was followed by waves of tor�  pedo planes, bombers, and fighters. Due to lax reconnaissance and the  fact that many vessels were undermanned since it was a Sunday morn�  ing, the base was unable to mount an effective defense. The Arizona was  completely destroyed; the Oklahoma capsized; the California, Nevada,  and West Virginia sank; more than 180 aircraft were destroyed; and numer�  ous vessels were damaged. In addition, more than 2,300 military person�  nel were killed. The �date which will live in infamy,� as U.S. Pres.  Franklin Roosevelt termed it, unified the American public and swept away  any earlier support of neutrality. On Dec. 8, 1941, Congress declared war  on Japan.</p><p>Pearl River River, central Mississippi, U.S. It flows southwest through  Jackson, then into Louisiana and the Gulf of Mexico. About 410 mi (660  km) long, it forms the boundary between Mississippi and Louisiana.

He was fired from the Baltimore Sun for  writing Washington Merry-Go-Round (1931, with Robert S. Allen), a gos�  sipy book about the scene in the U.S. capital. From 1932 he wrote an  influential syndicated column of the same name (with Allen until 1942;  from 1965 with Jack Anderson, who inherited it on Pearson�s death),  which specialized in muckraking.

He served in the Canadian House of Com�  mons from 1948 to 1968 and as minister of external affairs from 1948 to  1956. During the latter period he also led the Canadian delegation to the  UN; he was president of the UN General Assembly from 1952 to 1953.  In 1957 he received the Nobel Prize for Peace for his role in resolving  the Suez Crisis. He became head of the Liberal Party in 1958 and led it to  victory in elections in 1963. His government introduced a national pen�  sion plan and a family assistance program, broadened old-age security  benefits, and laid the groundwork for the National Free Medical Service.  In 1967 he rebuked visiting French Pres. Charles de Gaulle for his support  of separatism in Quebec. He retired in 1968.</p><p>Peary, Harold orig. Harrold Jese Pereira de Faria (b. July 25,  1908, San Leandro, Calif., U.S.�d. March 30, 1985, Torrance, Calif.)  U.S. actor. He created the colourful, arrogant character Throckmorton F.  Gildersleeve on the hit comedy series Fibber McGee and Molly in 1937.  He starred in his own popular radio serial, The Great Gildersleeve (1941�  50), considered the first spin-off created from another series. He later acted  in television series such as Blondie (1957) and Fibber McGee and Molly  (1959), and he appeared in the film Clambake (1967).

He joined the U.S. Navy in  1881 but was granted leaves of absence to pursue his Arctic expeditions.  He explored Greenland by dog sled in 1886 and 1891, finding evidence  that it was an island, and returned there in 1893-94, 1895, and 1896 to  transport large meteorites to the U.S. After announcing his intention to  reach the North Pole, he made several attempts between 1898 and 1905,  sailing on a specially built ship and sledding to within 175 mi (280 km)  of the pole. On April 6, 1909, accompanied by Matthew Henson (1866�  1955) and four Eskimo, he reached what he thought was the pole, and he  became widely acknowledged as the first explorer to attain that goal. (The  claim of his former colleague Frederick A. Cook to have reached the pole  in 1908 was later discredited.) In 1911 Peary retired from the navy with  the rank of rear admiral. Examination of Peary�s expedition diary and new  documents in the 1980s suggested that the point he reached may have  been 30-60 mi (50-100 km) short of the pole.</p><p>peasant Any member of a class that tills the soil as small landowners  or agricultural labourers. The peasant economy generally has a simple  technology and a division of labour by age and sex. The basic unit of pro�  duction is the family or household. Peasant families traditionally consume  what they produce, though a portion of their output may be sold in the  market or paid to a landlord. Productivity per worker and yields per unit  of land are usually low. Peasants as a class tend to disappear as a society  industrializes, though peasantlike social structures may persist under new  economic regimens. See also ejido; feudalism; hacienda; serfdom.</p><p>Peasants' Revolt or Wat Tyler's Rebellion (1381) First great  popular rebellion in English history. It was triggered by the poll tax of  1381, which angered labourers and artisans already resentful of the lim�  its on wages fixed by the Statute of Labourers (1351). Centred in south�  eastern England and East Anglia, the revolt was led by Wat Tyler (d.  1381), who marched into London with a band of Kentish rebels. They  captured the Tower of London and beheaded officials responsible for the  poll tax. Richard II promised reforms, but Tyler was killed in his presence  by the mayor of London. The last of the rebels were subdued in East  Anglia two weeks later.</p><p>Peasants' War (1524-25) Peasant uprising in Germany. Inspired by  reforms brought by the Reformation, peasants in western and southern  Germany invoked divine law to demand agrarian rights and freedom from  oppression by nobles and landlords. As the uprising spread, some peas�  ant groups organized armies. Although the revolt was supported by Hul-  drych Zwingli and Thomas MOntzer, its condemnation by Martin Luther  contributed to its defeat, principally by the army of the Swabian League.  Some 100,000 peasants were killed. Reprisals and increased restrictions  discouraged further attempts to improve the peasants� plight.</p><p>peat Organic fuel consisting of a light, spongy material formed in tem�  perate, humid environments by the accumulation and partial decomposi�  tion of vegetable remains under conditions of poor drainage. Peat  deposition is the first step in the formation of COAL. Dried peat bums</p><p>readily, with a smoky flame and a characteristic odour. It is used for  domestic heating and can be used to fire boilers. It is only a minor con�  tributor to the world energy supply, but large deposits occur in Canada,  China, Indonesia, Russia, Scandinavia, and the U.S. Major users include  Finland, Ireland, Russia, and Sweden.</p><p>peat moss or sphagnum moss Vsfag-nomN Any of more than 160  species of plants that make up the bryophyte genus Sphagnum, which  grow in dense clumps around ponds, in swamps and bogs, on moist, acid  cliffs, and on lakeshores from tropical to subpolar regions. These pale-  green to deep-red plants can hold 20 times their weight in water. As they  die and are compressed, they form organic peat, which is harvested and  dried as fuel, as seedbed cover, and as shipping packaging for plants and  live aquatic animals. Gardeners stir peat into soil to increase soil mois�  ture, porosity, and acidity and to reduce erosion.</p><p>pecan Nut and tree ( Carya illinoinensis) of the walnut family, native to  temperate North America.

He served in the U.S. Marines, studied drama at the University of  Southern California, and began working in television in the mid-1950s,  writing for and directing programs such as Gunsmoke and The Rifleman.  He made his debut as a film director with The Deadly Companions (1961),  which was followed by Ride the High Country (1962) and Major Dundee  (1965). Among his later films are The Wild Bunch (1969), considered his  finest, Straw Dogs (1971), Pat Garrett and Billy the Kid (1973), and Cross  of Iron (1977).

It empties into  the Rio Grande at the Amistad National Recreation Area. There are many  dams along the river, including the Alamogordo, Avalon, and Red Bluff  dams.</p><p>pectin Any of a class of carbohydrates found in certain plant cell walls  and tissues. They are principally composed of a galactose derivative,  galacturonic acid. In fruits, pectin keeps the walls of adjacent cells joined  together, helping them remain firm and hold their shape. As fruits become  overripe, the pectin breaks down to simple sugars that dissolve more  readily, so the fruits become soft and lose their shape. Because it forms a  thick, gel-like solution when added in small amounts to fruit acids, sugar,  and water, pectin is used to make jellies, jams, and marmalades. Its thick�  ening properties also make it useful in the confectionery, pharmaceutical,  and textile industries.</p><p>Pedersen Vpith-ar-sanV Holger (b. April 7, 1867, Gelballe, Den.�d.

(1909-13), he published works on Albanian, Armenian, Rus�  sian, and Indo-European dialects; on Lithuanian, Hittite, Tocharian, Czech,  and Turkish phonology; on the relationship of Indo-European languages to  the Semitic and Finno-Ugric languages; and on the origin of runes.</p><p>pedestal In Classical architecture, a support or base for a column, statue,  vase, or obelisk. It may be square, octagonal, or circular. A single pedestal  may also support a group of columns, or colonnade (see podium). The ped�  estal, which was first employed by Roman architects, consists (from bot�  tom to top) of three parts: the plinth, the dado (or die), and the cornice  (or cap).</p><p>pediatrics \,pe-de-'a-triks\ Medical specialty dealing with the develop�  ment, health, and diseases of children. It became a specialized area of  study in the 18th century, when the first children�s hospitals were founded.  Early pediatricians studied childhood diseases (see Thomas Sydenham) but  could do little to cure them. By the mid-20th century, when antibiotics and  vaccines had controlled most of these diseases in the developed world and  infant and child mortality had fallen, pediatrics changed its focus to nor�  mal growth and child development. Recently, behavioral and social  aspects of children�s health have been incorporated.</p><p>pedigree Record of ancestry or purity of breed. Pedigrees of domes�  ticated animals are maintained by governmental or private record asso�  ciations or breed organizations in many countries. In human genetics,  pedigree diagrams are used to trace the inheritance of a specific trait,  abnormality, or disease. Standard symbols are used to represent males,  females, mating (marriage), and offspring. The offspring symbols appear  from left to right in the order of birth and are connected to the marriage  line by a vertical line. Possession of the character under study is shown  by a solid or blackened symbol, and absence is shown by an open or clear  symbol.</p><p>pediment In Classical architecture, a triangular gable crowning a por�  tico or facade. The pediment was the crowning feature of the Greek temple  front. The pediment�s triangular wall surface, or tympanum, was often  decorated with sculpture. The Romans adapted the pediment as a purely  decorative form to finish doors, windows, and niches, sometimes using a</p><p>series of alternating triangular and segmentally curved pediments, a motif  revived in the Italian High Renaissance. Baroque-era designers developed  many varieties of broken, scrolled, and reverse-curved pediments.</p><p>pediment In geology, any relatively flat surface of bedrock (exposed  or lightly covered with soil or gravel) that occurs at the base of a moun�  tain or as a plain having no associated mountain. Pediments are most con�  spicuous in basin-and-range-type desert areas throughout the world, but  they also occur in humid areas. In the tropics, the surfaces tend to be cov�  ered with soil and obscured by vegetation. Many tropical river towns are  situated on pediments, which offer easier building sites than the steep  hillsides above or the river marshes below.</p><p>pedology \pi-'da-b-je\ A branch of soil science focusing on the for�  mation, morphology, and classification of soils as bodies within the natu�  ral landscape. Pedology seeks to understand how the properties and  distribution patterns of soils worldwide (collectively called the pedo-  sphere) have developed along with broader landforms, biogeochemical  environments, and habitats of living organisms. Through their understand�  ing of the causes and magnitudes of soil variations, pedologists help to  broaden knowledge of the surface of the Earth.</p><p>Pedrell \pa-'threl\, Felipe (b. Feb. 19, 1841, Tortosa, Spain�d. Aug.  19, 1922, Barcelona) Spanish musicologist and composer. He was largely  self-taught as a musician. A scholarship for study in Rome exposed him  to the great past of Spanish music preserved in archives there, and he set  about reviving the tradition by bringing to light both folk and older art  music and by promoting a national style of composition. His own works  include operas and orchestral and choral works. He is regarded as the  father of Spanish musical nationalism.</p><p>Pedro Vpa-dro, 'pa-drii\ I known as Dom Pedro (b. Oct. 12, 1798,  Lisbon, Port.�d. Sept. 24, 1834, Lisbon) First emperor of Brazil (1822�  31) and, briefly, king of Portugal. The son of John VI of Portugal, he  became regent of Brazil in 1821, but in 1822 he broke with Lisbon and  declared Brazil�s independence. The former colony became a constitu�  tional monarchy with Pedro its emperor. Strong opposition to his auto�  cratic manner and impatience with parliamentary procedure induced him  to abdicate in favour of his five-year-old son, Pedro II. When John VI died,  Pedro I became Portugal�s King Pedro IV, but he quickly abdicated in  favour of his daughter, the future Queen Maria II.

Second and last emperor of  Brazil (1831-89). He became emperor at age five when his father, Pedro  I, abdicated. After a period of regency, he was crowned in 1841. His con�  cern for his subjects, skill at arbitrating political disputes, and leadership  in economic matters brought stability to the country. He led Brazil into  the Paraguayan War, which brought Brazil prestige and territory. His  support eroded primarily over the issue of the imperial prerogatives.  Emancipation was proclaimed in 1888; in 1889 Pedro II was removed in  a military coup, and a republic was established.

July 2, 1850, London) Brit�  ish prime minister (1834-35, 1841�  46) and principal founder of the  Conservative Party. A member of Par�  liament from 1809, Peel served as  chief secretary for Ireland (1812-18)  and resisted efforts to admit Catho�  lics to Parliament. As home secretary  (1822-27, 1828-30), he reorganized  England�s criminal code.

He imposed an income tax, reorganized the  Bank of England, and initiated reforms in Ireland. Favouring reduced tar�  iffs on imports, he repealed the Corn Laws, which caused his government  to fall, but he continued to support free-trade principles in Parliament. He  was the chief architect of the mid-Victorian age of stability and prosper�  ity that he did not live to see.</p><p>Peel River River, northwestern Canada. It rises in western Yukon Ter�  ritory and flows east and then north into the Mackenzie River in the North�  west Territories, near Fort McPherson, a fur-trading post. It is 425 mi (684  km) long. Its upper course through Peel Plateau is characterized by can�  yons as deep as 1,000 ft (300 m). Its lower valley consists primarily of  nature preserves and game sanctuaries.</p><p>peerage Body of peers or titled nobility in Britain. The five ranks, in  descending order, are duke, marquess, earl (see count), viscount, and baron.  Until 1999, peers were entitled to sit in the House of Lords and exempted  from jury duty. Titles may be hereditary or granted for life.</p><p>Pegasus Vpe-go-sosV In Greek mythology, a winged horse. It sprang from  the blood of Medusa as she was beheaded by Perseus. Bellerophon captured  Pegasus and rode him in several of his exploits, including his fight with  the Chimera, but when he tried to ride the winged horse to heaven he was  unseated and killed, and Pegasus was placed in the sky as a constellation.  The flight of Pegasus is often regarded as a symbol of poetic inspiration.</p><p>pegmatite Vpeg-mo-.tltV Almost any wholly crystalline igneous rock  that is at least in part very coarse-grained, the major constituents of which  include minerals typically found in ordinary igneous rocks (such as gran�  ites) and in which extreme textural variations, especially in grain size, are  characteristic. Usually found as irregular dikes, lenses, or veins, pegma�  tite deposits occur in all parts of the world and are the chief source of  commercial feldspar, sheet mica, and beryllium, tantalum-niobium, and  lithium minerals.</p><p>Pei \'pa\, l(eoh) M(ing) (b. April 26, 1917, Canton, China) Chinese-  born U.S. architect. He immigrated to the U.S. in 1935 and studied at the  Massachusetts Institute of Technology and Harvard University. After  working for the architectural firm of Webb &amp; Knapp, he formed his own  partnership in 1955. Early in his career he created the building for the  National Center for Atmospheric Research, Boulder, Colo. (1968), which  mimics the broken silhouettes of the surrounding peaks. His innovative  East Building of the National Gallery of Art, Washington, D.C. (1978),  was hailed as one of his finest achievements. Other works include Bos�  ton�s John Hancock Tower (1973), Beijing�s Fragrant Hill Hotel (1982),  and a controversial glass pyramid for a courtyard at the Louvre Museum,  Paris (1989). Pei�s designs represent an elaboration on the rectangular  forms and irregular silhouettes of the International Style but with a  uniquely skillful arrangement of geometric shapes and a dramatic use of  varied materials, spaces, and surfaces; in his Miho Museum of Art, Shiga,  Japan (1997), for example, he achieved a harmony between the building,  much of it underground, and its mountain environment. In 1983 Pei  received the Pritzker Architecture Prize.</p><p>peine forte et dure Ypen-'fort-a-'dueA French "strong and hard  punishment" Formerly in English law, punishment inflicted on those  accused of a felony who refused to enter a plea. By a statute of 1275, the  peine was usually to imprison and starve the prisoner until he submitted;  in 1406 pressing by heavy weights was added to this. In one of the few  instances of its use in the American colonies, during the Salem witch tri�  als, 80-year-old Giles Corey, who had decided not to stand trial rather  than forfeit his family�s goods, was pressed to death by interrogators. The  practice was abolished in 1772.</p><p>Peipsi \'pap-se\, Lake Estonian Peipsi Jarv Lake, north-central  Europe, forming the boundary between Estonia and Russia. Lake Peipsi  is 60 mi (97 km) long and 31 mi (50 km) wide, and it is frozen for half  of the year. In 1242 the Russians, under Alexander Nevsky, defeated the  Teutonic Knights (see Teutonic Order) on the frozen lake in the �Battle on  the Ice,� forcing the order to relinquish claims to Russian lands.</p><p>Peipus, Lake See Lake Peipsi</p><p>Peirce Vpors, 'pirs\, Charles Sanders (b. Sept. 10, 1839, Cambridge,  Mass., U.S.�d. April 19, 1914, near Milford, Pa.) U.S. scientist, logi�</p><p>cian, and philosopher. He was the son of the mathematician and astrono�  mer Benjamin Peirce (1809-80). After attending Harvard University he  spent 30 years with the U.S. Coast Guard Survey (1861-91). As a scien�  tist, he is noted for his contributions to the theory of probability, the study  of gravity, and the logic of scientific methodology. He eventually aban�  doned the physical sciences to study logic, which in its widest sense he  identified with semiotics. He lectured on logic at Johns Hopkins Univer�  sity from 1879 to 1894, then spent the rest of his life writing in seclu�  sion. He is regarded as the founder of pragmatism. Though he made  eminent contributions to deductive logic, he was a student primarily of  �the logic of science��i.e., of induction and of �retroduction,� or �abduc�  tion,� the forming and accepting on probation of a hypothesis in order to  explain surprising facts. His lifelong ambition was to establish induction  and abduction as permanent branches of logic.</p><p>Peisistratus \pi-'sis-tro-t9s\ or Pisistratus (d. 527 bc) Tyrant of Ath�  ens (c. 560-559, 556-555, 546-527). Bom an aristocrat, he gained mili�  tary honours early. He first became tyrant in 560 after claiming an attempt  had been made on his life and appealing to the people to grant him a  bodyguard, which he used to help seize the Acropolis. His reign was  short-lived, but he gained power again briefly in 556, before being ousted  by Lycurgus and Megacles. After several years in exile, he returned with  an army in 546, took control, and remained in power until his death. A  patron of the arts, he executed many public works and tried to help small  farmers. His unification of Attica and improvement of Athens�s prosper�  ity helped make the city preeminent in Greece.</p><p>Peking See Beijing  Peking man See Zhoukoudian</p><p>Peking opera See jingxi</p><p>Peking University or Beijing University One of the oldest and  most important institutions of higher education in China. It was founded  as Capital College in 1898 and became a university in 1911. By 1920 it  had become a centre for progressive thought. During the Sino-Japanese  War (1937�45) it was temporarily relocated to Yunnan province. The first  disturbances of the Cultural Revolution began at Beijing University in  1966; education there ceased between 1966 and 1970. The university has  since reasserted its position as China�s foremost nontechnical university.  It has more than three dozen colleges and academic departments and  scores of research institutes.</p><p>Pekingese \,pe-k3-'nez\ Breed of long-haired toy dog developed in  ancient China, where it was held  sacred and was kept in Peking�s  Imperial Palace. Looting English  forces introduced the breed to the  West in 1860. Known as the �lion  dog� for its full mane but perhaps  also for its courage, it stands 6-9 in.</p><p>(15-23 cm) and weighs up to 14 lbs  (6.5 kg). It has hanging ears, a short,  wrinkled muzzle, and a black mask  across the face. The coat may be  solid or variegated. Chinese royalty  carried very small Pekingese, called �sleeve dogs,� in their sleeves.</p><p>Peko \'pa-ko\ In Estonian religion, an agricultural deity who aided the  growth of grain, especially barley. Peko was represented by a wax image  that was kept buried in the grain in the granary and brought out in early  spring for a ritual of agricultural fertility. At the end of a ceremonial feast,  leftovers were distributed among the poor, and the men competed in wres�  tling or fence jumping to determine who had the right to keep Peko in his  granary until the following year.</p><p>Pelagianism Npo-Ta-je-o-.ni-zomV Christian heresy of the 5th century  that emphasized free will and the goodness of human nature. Pelagius  (3547-after 418), a British monk who settled in Africa in 410, was eager  to raise moral standards among Christians. Rejecting the arguments of  those who attributed their sins to human weakness, he argued that God  made humans free to choose between good and evil and that sin is an  entirely voluntary act. His disciple Celestius denied the church�s doctrine  of original sin and the necessity of infant baptism. Pelagius and Celestius  were excommunicated in 418, but their views continued to find defend�  ers until the Council of Ephesus condemned Pelagianism in 431.</p><p>Pekingese</p><p>SALLY ANNE THOMPSON-EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1466 I Pele &#x25BA; pelvic inflammatory disease</p><p>Pele \'pa-,la\ orig. Edson Arantes do Nascimento (b. Oct. 23,  1940, Tres Cora^oes, Braz.) Brazil�  ian football (soccer) player, in his  time perhaps the most celebrated  athlete in the world. He joined the  Santos Football Club in 1956 and  helped lead that team to a world club  championship in 1962. He was part  of three Brazilian national teams that  won World Cup championships  (1958, 1962, 1970). In 1969, during  his 909th match, he scored his  1,000th goal. He combined kicking  power and accuracy with a remark�  able ability to anticipate other play�  ers� moves. In 1975 he joined the  New York Cosmos of the North American Soccer League (NASL); he  retired after leading the team to the league championship in 1977. He was  the 1978 recipient of the International Peace Award, and in 1980 he was  named Athlete of the Century.</p><p>Pelee \p9-'la\, Mount Active volcanic mountain, northern Martinique,  West Indies. It is northwest of Fort-de-France and is 4,583 ft (1,397 m)  high. A gently sloping cone, it supports luxuriant forests. A violent erup�  tion in 1902 destroyed the port of Saint-Pierre, killing about 30,000  people. A minor eruption occurred in 1929.</p><p>Pelew See Palau</p><p>Pelham, Henry (b. 1696�d. March 6, 1754, London, Eng.) British  prime minister (1743-54). He was elected to Parliament in 1717 and, as  a supporter of Robert Walpole, became secretary for war (1724) and pay�  master of the forces (1730). He succeeded Walpole as prime minister and  chancellor of the Exchequer in 1743 and led a stable Whig ministry with  parliamentary assistance from his brother, Thomas Pelham-Holles, duke  of Newcastle. Pelham resisted attempts to prolong the War of the Austrian  Succession and signed the Treaty of Aix-la-Chapelle (1748). After the war,  he introduced financial reforms, including lower military expenditures, a  reduced land tax, and a consolidation of the national debt.</p><p>Pelham-Holles, Thomas See Duke of Newcastle</p><p>pelican Any of about eight species constituting the genus Pelecanus  (family Pelecanidae), white or brown  birds distinguished by a large, elas�  tic throat pouch. Some species are 70  in. (180 cm) long, have a wingspan  of 10 ft (3 m), and weigh up to 30  lbs (13 kg). Most species drive fish  into shallow water and, using the  pouch as a dip net, scoop them up  and immediately swallow them.</p><p>Pelicans inhabit freshwaters and sea-  coasts in many parts of the world;  they breed in colonies on islands,  laying one to four eggs in a stick  nest. Chicks thrust their bills down  the parent�s gullet to obtain regurgi�  tated food.</p><p>Pella Ancient capital, Macedonia.</p><p>Located in northern Greece, north�  west of Thessaloniki, the city flour�  ished at the end of the 5 th century bc.</p><p>Originally known as Bounomos, it  developed rapidly under Philip II, but, after the Romans defeated the last  Macedonian king, it became a small provincial town. Archaeological  excavations began in 1957 and revealed large, well-built houses with  rooms with mosaic floors dating from the late 4th century bc. Pella was  the birthplace of Alexander the Great.</p><p>pellagra \p3-Ta-gro\ Nutritional disorder caused largely by a deficiency  of niacin, marked by skin lesions and digestive and neurological distur�  bances. Dermatitis usually appeal's first, with abnormal sensitivity to sun�  light. It may look like a severe sunburn, later becoming reddish brown,  rough, and scaly. Diarrhea usually alternates with constipation, along with  mouth and tongue inflammation and cracking and dry scaling of the lips.</p><p>Later, mental abnormalities may include nervousness, depression, and  delirium. Mild cases of niacin deficiency respond to a well-balanced diet  alone. Pellagra still occurs where diets consist mostly of corn, which is low  in both niacin and tryptophan (converted to niacin in the body), with little  or no protein-rich food. It can also be a side effect of chronic alcoholism.</p><p>Peloponnese Vpe-lo-po-.nezX Peninsula, forming the southern part of  mainland Greece. A large, mountainous body of land jutting south into  the Mediterranean Sea, the peninsula has an area of 8,278 sq mi (21,439  sq km) and is joined to the rest of mainland Greece by the Isthmus of  Corinth. The Mycenaean civilization flourished there in the 2nd millen�  nium bc at Mycenae and Pylos. Its chief cities during the classical period  were Corinth and Sparta. Under the Romans it was part of the province  of Achaea from 146 bc to c. 4th century ad. It was part of the Byzantine  Empire until it was taken by the Franks; they held it in the 13th�15th cen�  turies, when it was often known as Morea. The modern city of Patras  (pop., 2001: 163,446), in the north, is a commercial centre.</p><p>Peloponnesian League or Spartan Alliance Military coalition  of Greek city-states led by Sparta, formed in the 6th century bc. League  decisions about war, peace, or alliance were determined by congresses  summoned by the Spartans. The league was a major force in Greek affairs,  forming the core of resistance to the Persian invasions in 490 and 480 and  fighting Athens in the Peloponnesian War. Its power declined after its  defeat at Leuctra in 371, and the league disbanded in 366/365.</p><p>Peloponnesian War (431-404 bc) War fought between Athens and  Sparta, the leading city-states of ancient Greece, along with their allies,  which included nearly every other Greek city-state. Its principal cause was  a fear of Athenian imperialism. The Athenian alliance relied on its strong  navy, the Spartan alliance on its strong army. The war fell into two peri�  ods, separated by a six-year truce. Fighting broke out in 431, with Peri�  cles commanding the Athenians. In the first 10 years, Archidamus led the  Spartans to defeats. Plague struck Athens in 429, killing Pericles and much  of the army. In 428 Cleon almost convinced Athens to massacre the rebel�  lious citizens of Mytilene on Lesbos, but Athens rescinded the order. In  421 both states agreed to accept the Peace of Nicias. This lasted six years,  until Athens launched its disastrous Sicilian expedition. By 413 Athens�s  forces were demolished. In 411 an oligarchy briefly took power. When  democratic leaders were restored by the navy later that year, they refused  Spartan peace offers, and the war continued until 405, when the Athenian  navy was destroyed at the Battle of Aegospotami with Persian help. Under  blockade, Athens surrendered in 404. Its empire was dismantled, and the  Spartans installed the Thirty Tyrants.</p><p>Pelops Vpe-.laps, 'pe-,laps\ In Greek mythology, founder of the Pelopid  dynasty at Mycenae. Pelops was a grandson of Zeus. His father, Tantalus,  cooked and served Pelops to the gods at a banquet, and only Demeter,  mourning the loss of her daughter, Persephone, was distracted enough to  eat from the dish. The gods ordered the body restored, but the shoulder,  Demeter�s portion, was missing, and the boy was given a replacement of  ivory. In another story, Poseidon, helped Pelops gain the hand of Hippo-  damia, daughter of King Oenomaus of Pisa.</p><p>pelota \p3-'lo-t9\ (Spanish: �little ball�) Any of several games in which  players take turns, using a glove or implement, hitting a rubber ball either  directly at one another or off a wall. The latter version is related to hand�  ball and jai alai, which are played by two or four players on one-, two-, or  three-walled courts using gloves, rackets, or bats. In Spain and elsewhere,  pelota is a professional sport on which spectators wager.</p><p>Pelusium Xpo-'lii-she-omX Ancient Egyptian city. Located on what was  once the easternmost mouth of the Nile River, its ruins lay southeast of  modern Port Said. Beginning in the 26th dynasty (c. 7th century bc), it  was the main frontier fortress facing Palestine and was a customs post for  Asian goods. In 522 bc the Achaemenian Persians, under Cambyses II,  defeated the pharaoh Psamtik III there. In Roman times it was a station  on the trade route to the Red Sea; its ruins date from the Roman period.</p><p>pelvic inflammatory disease (PID) Acute inflammation of the pel�  vic cavity in women, caused by bacterial infection (usually gonorrhea or  CHLAMYDIA) of the REPRODUCTIVE SYSTEM. Usually a SEXUALLY TRANSMITTED DISEASE,  it occurs mainly in sexually active women under age 25, more often in  those using intrauterine devices (IUDs). PID can resemble gonorrhea,  with abdominal and lower pelvic pain, chills, nausea, fever, and thick,  foul-smelling vaginal discharge. Fallopian tube scarring can cause infer�  tility and ectopic pregnancy.

Lazaro Cardenas nationalized 17 foreign oil com�  panies to create Pemex, the largest Latin American petroleum company  and a major world exporter of fossil fuel. Pemex engages in exploration,  production, refining, transportation, storage, distribution, and sales of oil  and natural gas. In the 1970s promising oil discoveries gave rise to a  national spending spree, led by the flamboyant Pres. Jose Lopez Portillo  and financed by massive borrowing. Crude-oil production tripled, but  when the international price of oil collapsed in 1981, Lopez Portillo raised  Mexican oil prices. The country was virtually bankrupt within one year.  Economic reforms have since contributed to greater stability. At the turn  of the 21st century, Pemex accounted for nearly 40% of the Mexican gov�  ernment�s income.</p><p>pen drawing Artwork executed wholly or in part with pen and ink,  usually on paper. It is fundamentally a linear method of making images.  Artists who wish to suggest three-dimensional forms use hatching and  cross-hatching or washes of colour laid onto the drawing with a brush.  The three most common types of ink are black carbon ink, the finest type  being Chinese ink or the modern India ink; brown ink, which was popu�  lar with the Old Masters; and iron gall, a chemical ink. The three pen  types are quill, reed, and metal. Quill pens were most popular for their  flexibility and ability to be sharpened to extreme fineness. Steel became  the predominant pen type by the 20th century.</p><p>penal colony Distant or overseas settlement established to punish  criminals with forced labour and isolation from society. Such colonies  were developed mostly by the English, French, and Russians. Britain sent  criminals to its American colonies until the Revolutionary War; Australia  was principally a penal colony from its colonization until the mid-19th  century. French Guiana, site of a French penal colony, was infamous for  its inhumanity; Devil's Island was still operating during World War II.  Russian penal colonies were established in Siberia under the tsars but were  most widely used during the Stalin era. Notorious for their harsh punish�  ments and underfeeding, most penal colonies have now been abolished.</p><p>Penang \po-'naq\ Malay Pinang Island (pop., 2000 prelim.:  1,225,501), Malaysia, off the northwestern coast of the Malay Peninsula,  part of the state of Pulau Pinang. The capital and chief port is George  Town (pop., 2000 prelim.: 180,573), in the northeast. British colonization  began in 1786. In 1826 Penang (known until 1867 as Prince of Wales  Island) combined with Malacca and Singapore to form the Straits Settle�  ments. From the mid-19th century it was a market for tin and rubber. In  1948 it became part of the Federation of Malaya, later Malaysia. In the  late 20th century it became Malaysia�s prime tourist centre, with resort  hotels mainly on the northern coast at Batu Feringgi.</p><p>Penates \po-'na-tez, po-'na-tez\ Roman household gods. They were wor�  shiped privately as protectors of the household and also publicly as pro�  tectors of the Roman state. They were sometimes associated with other  deities of the house, such as Vesta, and their name was often used inter�  changeably with that of the Lares. Each house had a shrine with their  images, which were worshiped at the family meal and on special occa�  sions. Offerings were portions of the regular meal or of special cakes,  wine, honey, and incense. The number and precise identities of the Penates  were a puzzle even to the ancients.</p><p>pencil drawing Drawing executed with a pencil, an instrument made  of graphite enclosed in a wood casing. Though graphite was mined in the  16th century, its use by artists is not known before the 17th century. In  the 17th�18th century, graphite was used primarily to make preliminary  sketches for more elaborate work in another medium, seldom for finished  works. By the late 18th century, an ancestor of the modern pencil was  constructed by inserting a rod of natural graphite into a hollow cylinder  of wood. Pencil rods produced from mixtures of graphite and clays, true  prototypes of the modem graphite pencil, were introduced in 1795. This  improvement allowed for better control and encouraged wider use. The  great masters of pencil drawing kept the elements of a simple linearism  with limited shading, but many artists in the 18th�19th century created  elaborate effects of light and shade by rubbing the soft graphite particles  with a tightly rolled paper or chamois.</p><p>pendant or pendent In architecture, a sculpted ornament suspended  from a vault or ceiling, especially an elongated boss (carved keystone) at</p><p>the junction of the intersecting ribs of the fan vaulting associated with the  English Perpendicular style. In stone ceilings, the use of pendant vaulting  was a solution to the difficulty of adapting fan vaulting to very wide  church naves. Strong transverse arches were made to span the area, and  these in turn supported the elongated keystones. Intermediate rib and  panel vaults sprang from these pendants.</p><p>pendant Ornament suspended from a bracelet, earring, or necklace and  derived from the primitive practice  of wearing amulets or talismans  around the neck. The practice dates  from the Stone Age, when pendants  consisted of objects such as teeth,  stones, and shells. Commemorative  and decorative pendants were com�  mon in ancient Egypt, Greece, and  Rome. In the Middle Ages reliquar�  ies, or devotional pendants, and  crosses were created with jewels. By  the beginning of the 16th century,</p><p>Renaissance artists were creating  pendants for decorative rather than  religious use. The late 19th-century  Art Nouveau movement often fea�  tured women�s figures, butterflies, or  flowers on pendants.</p><p>pendentive In architecture, a tri�  angular segment of a spherical sur�  face that forms the transition between the circular plan of a dome and the  polygonal plan of its supporting structure. The problem of placing a round  dome on a square base assumed growing importance to Roman builders,  but it remained for Byzantine architects to recognize the possibilities of  the pendentive and fully develop it (see Hagia Sophia). One of the great  architectural inventions of all time, the pendentive became very impor�  tant in the Renaissance and Baroque periods. As a result of Byzantine  influence, pendentives are also frequent in Islamic architecture. The vault�  ing form in which the curve of the pendentive and dome is continuous is  known as a pendentive dome.</p><p>Penderecki \,pen-d3-'ret-ske\, Krzysztof (b. Nov. 23, 1933, Debica,  Pol.) Polish composer and conductor. He studied composition at the  Krakow Conservatory and would later serve as its director (1972-87). His  early music (1960-74) involved dense note clusters and unorthodox  sounds, and he developed his own musical notation to convey the desired  effects, resulting in vivid works that attracted international attention,  including Threnody for the Victims of Hiroshima (1960), Stabat Mater  (1962), the St. Luke Passion (1963-65), and the opera The Devils of Lou-  dun (1969). After 1975 he embraced a more traditional approach with  works such as the opera Paradise Lost (1978), concertos for violin (1977),  cello (1982), and viola (1983), and Lux aeterna (1983).</p><p>Pendergast, Thomas J(oseph) (b.

He was active in  municipal politics in Kansas City, Mo., and became the political boss of the  city�s Democrats by 1916. His political machine dominated city and state  politics for almost 25 years and influenced national Democratic conven�  tions. He helped Harry S. Truman in his early political career. Attacked by  opponents for allowing corrupt practices in Kansas City, he was convicted  of income-tax evasion in 1939 and served one year in prison.</p><p>Pendleton, George (Hunt) (b. July 29, 1825, Cincinnati, Ohio,  U.S.�d. Nov. 24, 1889, Brussels, Belg.) U.S. politician. He served in the  U.S. House of Representatives from 1857 to 1865 and was the unsuc�  cessful Democratic candidate for vice president (with George B. McClel�  lan) in 1864. A member of the Greenback movement, he advocated the Ohio  Idea for redeeming American Civil War bonds. From 1879 to 1885 he  served in the U.S. Senate, where he sponsored the Pendleton Civil Service  Act.

A simple pendulum consists of a  bob (weight) suspended at the end of a string. The periodic motion of a  pendulum is constant, but can be made longer or shorter by increasing or  decreasing the length of the string. A change in the mass of the bob alone  does not affect the period. Because of their constancy, pendulums were  long used to regulate the movement of clocks. Other, special kinds of  pendulums are used to measure the value of g, the acceleration due to  gravity, and to show that the earth rotates on its axis (see Foucault pen�  dulum).</p><p>peneplain Vpe-n3-,plan\ Gently undulating, almost featureless plain  near sea level. This would form, theoretically, by various erosional pro�  cesses that reduce areas of initially high relief produced by active uplift  to areas of virtually no relief. The lack of present-day peneplains tends  to discredit the theory, but some geomorphologists propose that large  areas of low relief at high altitude in some mountains are evidence of  uplifted peneplains. Others question whether the dynamic relationship  between erosion and rock type would ever allow the development of a  peneplain, even over very long timespans.</p><p>Peneus River See Pinios River</p><p>penguin Any of 17 species (order Sphenisciformes) of flightless sea�  birds that breed mainly on islands in subantarctic waters and on cool  coasts of Africa, Australia, New Zealand, and South America. A few spe�  cies inhabit temperate regions, and the Galapagos penguin (Spheniscus  mendiculus) lives in the equatorial tropics off South America. Species dif�  fer mainly in size and head pattern; all have a dark back and a white belly.  The smallest species, the little blue penguin {Eudyptula minor), is about  14 in. (35 cm) tall; the largest, the emperor penguin (Aptenodytes for-  steri), is almost 4 ft (120 cm) tall. At sea for weeks at a time, flocks feed  on fish, squid, and crustaceans.</p><p>penicillin Antibiotic derived from the Penicillium mold. It was discovered  in 1928 by Alexander Fleming; by 1940, Howard Walter Florey, Ernst Boris  Chain, and others had produced commercial quantities that proved vital  to the treatment of war casualties, making penicillin the first successful  antibiotic for human bacterial infections. Many natural and semisynthetic  (ampicillin, amoxicillin) variants have since been produced. All work by  inhibiting the enzymes responsible for bacterial cell wall synthesis (and  therefore do not work against microorganisms without cell walls or with  certain variant cell walls; e.g., the tuberculosis bacillus). Among the bac�  teria susceptible to penicillin are those causing strep throat, spinal men�  ingitis, gas gangrene, and syphilis. Overuse has led to drug resistance in some  strains. Penicillin�s chief side effect is allergy, which can be life-  W threatening.</p><p>wm Penicillium V.pe-ns-'si-le-omV Any blue or green mold in the genus Pen-</p><p>!&#x25A0; icillium (kingdom Fungi; see fungus).

After French forces occupied Portugal (1807) and  Napoleon installed his brother Joseph Bonaparte as king of Spain (1808),  a rebellion in Madrid began what was called in Spain �the War of Inde�  pendence,� and insurrections soon erupted in other cities. By 1810 the  French overcame the Spanish rebels in Madrid and elsewhere in Spain.  Meanwhile, the British under the future duke of Wellington landed in  Portugal (1808), where they fought the French in inconclusive campaigns  until 1812. After Napoleon withdrew French forces to bolster his invasion  of Russia, Wellington began his gradual advance into Spain. The British  victory at the Battle of Vitoria (1813) and their march into southwestern  France forced the French to withdraw from Spain and to reinstall Ferdi�  nand VII as king (1814).</p><p>penis Male sex organ, which also provides the channel for urine to leave  the body. Three long columns of tissue extend through its length, covered  by elastic tissue and a thin layer of skin. One expands at the tip into a  mushroom-shaped structure (glans penis) and contains the urethra (see  urinary system), which ends in a slitlike opening. In sexual arousal, blood  fills spaces in the tissue, and blood vessels constrict to hold it there,</p><p>enlarging and hardening the penis in an erection. The foreskin, a circular  fold of skin covering the glans, is often removed (see circumcision). See  also REPRODUCTIVE SYSTEM.</p><p>Penn, Irving (b. June 16, 1917, Plainfield, N.J., U.S.) U.S. photogra�  pher. He aspired to be a painter but at 26 took a job designing photo�  graphic covers for Vogue and soon was established as a fashion  photographer. His austere fashion images communicated elegance and  luxury through compositional refinement and clarity of line rather than  through the use of elaborate props and backdrops. He branched out into  portraiture after World War II and became much admired as a portraitist  of celebrities. In his portraits the subject is usually posed before a bare  backdrop and photographed in natural northern light. The resulting images  combine simplicity and directness with great formal sophistication.</p><p>Penn, William (b. Oct. 14, 1644, London, Eng.�d. July 30, 1718,  Buckinghamshire) English Quaker leader and founder of Pennsylvania.  Expelled from Oxford for his Puritan beliefs, he was sent to manage the  family estates in Ireland, where he joined the Society of Friends in 1667.  He was imprisoned four times for stating his Quaker beliefs in print and  in speech; one of his trials resulted in the precedent-setting Bushell�s  Case, which established the independence of juries. In The Great Case of  Liberty of Conscience (1670), Penn advocated religious toleration and  envisioned a colony based on religious and political freedom. On his  father�s death, he inherited his estates and his influence with Charles II,  who granted him a vast province on the Delaware River in payment for  debts owed his father. In 1682 he drafted a Frame of Government that  established freedom of worship in the settlement. Upon his arrival later  that year, he negotiated a series of treaties with the local Indians. In 1684  he traveled to England to defend his interests against claims by neigh�  bouring Maryland. With the accession of his friend the duke of York as  James II, he secured the release of imprisoned Quakers. He returned to  Pennsylvania in 1699, where he wrote the Charter of Privileges, which  allowed the assembly greater autonomy. The years after his return to  England in 1701 were clouded by debt and illness.</p><p>Penney, J(ames) C(ash) (b. Sept. 16, 1875, Hamilton, Mo., U.S.�d.  Feb. 12, 1971, New York, N.Y.) U.S. merchant. He became a partner in  a dry-goods store in Wyoming in 1902 and five years later bought out his  partners� shares to launch what became the J.C. Penney Co. His stores  offered a wide variety of inexpensive merchandise, and he offered profit-  sharing plans, first to managers and later to all employees. By 1929 the  company had 1,392 stores across the U.S., and at the time of Penney�s  death it was the second largest merchandiser in the country, behind Sears,  Roebuck and Co.</p><p>Pen nines Vpe-.nlnzX Upland mass, northern England.

The state is  bounded on the north by Lake Erie and New York; on the east by New  York and New Jersey; on the south by Delaware, Maryland, and West  Virginia; and on the west by the panhandle of West Virginia and by Ohio;  the Delaware River forms part of the eastern boundary. The Monongahela  River unites with the Allegheny River at Pittsburgh to form the Ohio River.  The area was inhabited by Indian peoples, including the Shawnee and  Delaware, when Europeans arrived in the 17th century. In 1664 the English  seized control of the region, and in 1681 the English king granted a char�  ter to William Penn, who established a Quaker colony based on religious  tolerance in 1682. Much of the fighting of the French and Indian War took  place there. The first and second Continental Congresses met in Philadel�  phia, and the Declaration of Independence was signed there in 1776. One  of the original states of the Union, it was the second state to ratify the  U.S. Constitution in 1787. During the American Civil War it was a centre  of military activity (see Battle of Gettysburg). The postwar period brought  great economic, industrial, and population growth, consolidating the  state�s position as a major commercial power. It is one of the most pros�  perous states, with an economy based on farming, mining, manufactur�  ing, and high technology.

With the founding of the first medical school  in North America (1765), it became a university. Today, in addition to its  college of arts and sciences and its medical school, it includes a college of  general studies and schools of business (the Wharton School), communi�  cation (the Annenberg School), education, engineering, fine arts, law, nurs�  ing, dentistry, veterinary medicine, and social work. Its institutes include  the Wistar Institute of Anatomy and Biology and the Phipps Institute of  Genetics and Community Diseases.

It was chartered  in 1846 by the Pennsylvania legislature to build a line between Harris�  burg and Pittsburgh, and its passenger service began two years later. By  purchasing the Pittsburgh, Fort Wayne and Chicago Railway in 1856, the  company extended its service to Chicago. After the Civil War it expanded  to St. Louis, Mo., and Cincinnati, Ohio, in the west and Norfolk, Va., in  the south, with 10,000 mi (16,000 km) of track at its greatest extent. It  began to lose money in the mid 20th century, and in 1968 it merged with  its competitor, the New York Central, to form the Penn Central Transpor�  tation Co. Penn Central declared bankruptcy in 1970; its passenger ser�  vice was taken over by Amtrak in 1971 and its assets by Conrail in 1976.  See also J.

Influential historical works  have included Cesare Beccaria�s On Crimes and Punishments (1764), Jer�  emy Bentham�s �Panopticon� scheme (c. 1800), Cesare Lombroso�s Crime  (1876), and Michel Foucault�s Discipline and Punish (1975).</p><p>pension Series of periodic money payments made to a person who  retires from employment because of age, disability, or the completion of  an agreed span of service. The payments generally continue for the rest  of the recipient�s natural life, and they are sometimes extended to a widow  or other survivor. Military pensions have existed for many centuries; pri�  vate pension plans originated in Europe in the 19th century. There are two  basic types of pension plans: defined contribution and defined benefit. A  defined contribution plan invests a defined amount each pay period. The  individual may have some discretion as to how the money is invested.  The benefit, the amount of the pension, depends on the success of those  investments. A defined benefit plan pays a known amount according to  some formula, but the amount invested in the fund may vary. Pensions</p><p>may be funded by making payments into a pension trust fund or by the  purchase of annuities from insurance companies. In plans known as mul�  tiemployer plans, various employers contribute to one central trust fund  administered by a joint board of trustees.</p><p>Pentagon Huge five-sided building (1941-43) in Arlington, Va., that is  the headquarters of the U.S. Department of Defense.

The disciples began to speak in the many languages of the  people assembled there, a sign that the disciples should spread the Chris�  tian message throughout the world. Jewish Pentecost was a thanksgiving  feast for the first fruits of the wheat harvest and was associated with  remembrance of God�s gift of the Law to Moses on Mount Sinai.

It is also the name of the Jewish celebration of Shavuot  (�Festival of Weeks�).</p><p>Pentecostalism Protestant religious movement that originated in the  U.S. in the 19th-20th century. It is characterized by a belief that all Chris�  tians should seek a postconversion religious experience called baptism with  the Holy Spirit. The experience corresponds to the descent of the Holy  Spirit on the twelve Apostles (Pentecost) and is evidenced by speaking in  tongues, prophesying, and healing. Pentecostalism grew out of the 19th-  century Holiness movement and shares its emphasis on biblical literalism,  conversion, and moral rigor. The charismatic movement in Roman Catho�  lic and mainstream Protestant denominations represents the same spirit.  Today there are many Pentecostalist denominations in the U.S. and around  the world, including the Assemblies of God. Penetcostalism has been espe�  cially successful in the Caribbean, Latin America, and Africa.</p><p>penthouse Enclosed area on top of a building. A penthouse can be an  apartment on the roof or top floor of a building or a structure on the roof  housing the top of an elevator shaft, air-conditioning equipment, or stairs  leading to the roof. A penthouse is usually set back from the vertical face  of a building, but as a real-estate term, penthouse may refer to any top  floor, regardless of setbacks. Though the word now often suggests a luxu�  rious apartment with a panoramic view, historically a penthouse was a  lean-to, shed, or other small structure attached to a comparatively large  building.</p><p>Pentium Family of microprocessors developed by Intel Corp.

The Penu�  tian hypothesis was proposed by Roland B. Dixon and Alfred L. Kroeber  in 1913 and refined by Edward Sapir in 1921. Like the Hokan hypothesis  (see Hokan languages), it attempted to reduce the number of unrelated  language families in one of the world�s most linguistically diverse areas.  At its core was a group of languages spoken along California�s central  coast and in the Central Valley, including Ohlone (Costanoan), Mi wok,  Wintuan, Maidu, and Yokuts. Sapir added Oregon Penutian (languages  once spoken in eastern Oregon), Chinookan (spoken along the lower  Columbia River), Plateau Penutian (languages of Plateau Indian peoples),  Tsimshian (spoken in western British Columbia), and Mexican Penutian  (spoken in southern Mexico). Aside from the Mexican group, all the lan�  guages are today either extinct or spoken almost exclusively by older  adults. Though the hypothesis remains unproven, at least some languages  of the group are probably related to each other.</p><p>Penzias \'pent-se-9s\, Arno (Allan) (b. April 26, 1933, Munich, Ger.)

In 1989 he was  awarded the Medal of Freedom.</p><p>peppermint Strongly aromatic perennial herb (. Mentha piperita, mint  family), source of a widely used flavouring. Native to Europe and Asia,  it has been naturalized in North America. The stalked, smooth, dark green  leaves and blunt, oblong clusters of pinkish lavender flowers are dried for  use as a flavouring agent. Oil of peppermint is widely used to flavour  confectionery, chewing gum, toothpastes, and medicines. The oil also  contains menthol, long used medicinally as a soothing balm.</p><p>PepsiCo, Inc. U.S. conglomerate. The soft drink Pepsi-Cola was cre�  ated by a pharmacist, Caleb D. Bradham, who gave his tonic its name  (from Greek pepsis, �digestion�) in 1898 and incorporated the Pepsi-Cola  Co. in 1902. After two bankruptcies and several reincorporations, the  Pepsi-Cola trademark and assets were bought in 1931 by Charles G. Guth,  who improved the formula and marketed a 12-ounce bottle for five cents  with huge success. Pepsi-Cola merged with the soda-fountain chain Loft,  Inc., in 1941, and in 1965 it merged with Frito-Lay, Inc., adopting its cur�  rent name, PepsiCo, Inc. In the 1970s and �80s PepsiCo bought restau�  rant chains such as Pizza Hut, Taco Bell, and Kentucky Fried Chicken,  but in 1997 it spun off its restaurant business into a separate company,  Tricon Global Restaurants. In 2001 the Quaker Oats Co. merged with  PepsiCo.</p><p>pepsin Powerful enzyme in gastric juice (see stomach) that partially  digests proteins in food. Glands in the stomach lining make pepsinogen,  a zymogen (enzyme precursor) converted to pepsin by the hydrochloric acid  in gastric juice. Pepsin is active only in the acid environment of the stom�  ach (pH 1.5-2.5 or less); it is ineffective in the intestine (pH 7, neutral).  It is used commercially in some cheese making, in the leather industry to  remove hair and residual tissue from hides, and in the recovery of silver  from discarded photographic films by digesting the gelatin layer that holds  the silver.</p><p>peptic ulcer Sore that develops in the mucous membrane of the stom�  ach (more frequent in women) or duodenum (accounting for 80% of ulcers  and more frequent in men) when its ability to resist acid in gastric juice  is reduced.

Peptide chains longer than a few dozen amino  acids are called proteins. Biosynthesis of peptides from a succession of  amino acids carried by transfer RNA molecules takes place on ribosomes  and is catalyzed and controlled by enzymes. Many hormones, antibiotics,  and other compounds that participate in life processes are peptides.</p><p>Pepys \'peps\, Samuel (b. Feb. 23, 1633, London, Eng.�d. May 26,  1703, London) English diarist and  public official. Born into a humble  family, Pepys was appointed about  1659 as a clerk in the office of the  Exchequer, where on Jan. 1, 1660, he  began the diary for which he is  chiefly known. He steadily improved  his position, in time becoming sec�  retary of the Admiralty, a member of  Parliament, president of the Royal  Society, trusted confidant of Charles  II and James II, and friend of the great  scholars of his age. His diary (pub�  lished 1825), which he kept through  1669, presents a fascinating picture  of the official and upper-class life in  Restoration London, with vivid, hon�  est accounts of ordinary as well as  great events, including the Plague  and the Great Fire of London.</p><p>Pequot \'pe-,kwat\ North Ameri�  can Indian people now living in east�  ern Connecticut, U.S. Pequot is an Algonquian language, and the name  is derived from an Algonquian word meaning �destroyers.� Pequot sub�  sistence was based on corn cultivation, hunting, and fishing. The people  were at one time united with the Mohegan. For a brief period the Pequot  lived amicably with the American colonists, but relations became strained  as land pressures grew. Puritan clergymen encouraged violence against  the Pequot as infidels, and in 1636 war broke out, resulting in large losses.  Further destruction resulted when the remaining Pequot were placed under  the control of other tribes. In 1655 the few remaining Pequot were  resettled on the Mystic River. The two groups of Pequot number about</p><p>1 , 000 .</p><p>Perahia \p3-'ri-3\, Murray (b. April 19, 1947, New York, N.Y., U.S.)  U.S. pianist. He was trained at the Mannes College of Music in New York  City. He won the Leeds International Piano Competition by unanimous  vote in 1972, and in 1975 he shared the first Avery Fisher Prize. From  1982 he was music director of the Aldeburgh Festival and made his home  in England. He is best known for his sensitive recordings of Wolfgang  Amadeus Mozart�s concertos, conducted from the keyboard.</p><p>Peranakan \,per-3-'na-k3n\ Any native-born Indonesian of mixed  Indonesian and foreign ancestry. The term often refers to the Peranakan  Chinese, the largest and most important Peranakan group, who formed a  stable community by the mid-19th century, partly adopting the indigenous  way of life and generally speaking the native tongue. By contrast, in the  early 20th century a large wave of Chinese immigration created a Totok  (foreign-bom) Chinese community. Unlike the Peranakans, the Totoks  retained their own Chinese dialects and remained China-oriented.</p><p>perception Process of registering sensory stimuli as meaningful expe�  rience. The differences between sensation and perception have varied  according to how the terms are defined. A common distinction is that sen�  sations are simple sensory experiences, while percepts are complex con�  structions of simple elements joined through association. Another is that  perception is more subject to the influence of learning. Though hearing,  smell, touch, and taste perceptions have all been explored, vision has  received the most attention. Structuralist researchers such as Edward Brad�</p><p>ford Titchener focused on the constituent elements of visual perceptions,  whereas Gestalt psychology has stressed the need to examine organized  wholes, believing humans are disposed to identifying patterns. Visual  objects tend to appear stable despite continually changing stimulus fea�  tures (such as ambient light, perspective, ground vs. figure arrangement),  which enables an observer to match a perceived object with the object as  it is understood to exist. Perceptions may be influenced by expectations,  needs, unconscious ideas, values, and conflicts.</p><p>Perceval Hero of Arthurian legend. His childlike innocence protected  him from worldly temptation. In Chretien de Troyes�s 12th-century Le  Conte du Graal, Perceval visits the castle of the wounded Fisher King  and sees the Grail, but he fails to ask about it and therefore fails to heal  the Fisher King. He subsequently sets out in search of the Grail and grows  spiritually. In later Grail legend he was displaced by Galahad as the hero  of the Grail quest but continued to play an important role. His story was  told in Wolfram von Eschenbach�s 13th-century Parzifal, which provided  the basis for Richard Wagner�s opera Parsifal (1882).</p><p>Perceval Vpar-ss-volX, Spencer (b. Nov. 1, 1762, London, Eng.�d.  May 11, 1812, London) British prime minister (1809-12). He entered  Parliament in 1796 and supported William Pitt�s policy of war with France.  He served as attorney general (1802-06) and as chancellor of the Exche�  quer (1807-09). As premier from 1809, he was noted as an efficient  administrator but also for his opposition to religious tolerance. He was  assassinated by a deranged man who had applied to him for redress of a  complaint against the government.</p><p>perch Either of two species (family Percidae, order Perciformes) of popu�  lar food and sport fishes: the Eurasian common perch {Perea fluviatilis) or  the North American yellow perch (P flavescens). Some consider the two a  single species. Both have one spiny and one soft-rayed dorsal fin. Perches  are carnivores of quiet ponds, lakes, streams, and rivers. The common  perch is greenish, with dark vertical bars on the sides and reddish in the  lower fins. It grows to 6 lbs (3 kg), rarely more. The yellow perch, similar  but yellower, grows to about 15 in. (40 cm) and weighs up to 2 lbs (1 kg);  it is a popular game fish. See also sauger, sea bass, walleye.</p><p>Percheron Vpor-cho-.ranN Heavy breed of draft horse that originated in  France�s Perche region. The breed probably stems from the medieval  Flemish �great horse,� which was modified by Oriental and draft-type  blood to produce animals for heavy farm work. Percherons became popu�  lar in the U.S. in the 1850s and influenced U.S. agriculture more than any  other draft breed. They average 16-17 hands (64-68 in. [163-173 cm])  high and weigh 1,900-2,100 lb (860-950 kg). Common colours are black  and gray. Agile and energetic for their size, they have a mild disposition.</p><p>percussion instrument A musical instrument that is struck (or some�  times shaken or scraped) to produce sound. This category includes instru�  ments whose own hard substance is made to vibrate (idiophones) and  instruments that include a tight membrane that vibrates (membrano-  phones). Percussion instruments may produce tones of definite or indefi�  nite pitch. Their primary function is often rhythmic, but many are used  as melody instruments. They include the bell, carillon, cymbal, drum, dul�  cimer, GAMELAN, GLOCKENSPIEL, MARIMBA, PIANO, STEEL DRUM, TABLA, TAMBOURINE,  TIMPANI, VIBRAPHONE, and XYLOPHONE.</p><p>Percy, John (b. March 23, 1817, Nottingham, Nottinghamshire,  Eng.�d. June 19, 1889, London) British metallurgist. He turned to met�  allurgy after obtaining a medical degree, and in 1848 he devised a pro�  cess for extracting silver from its ores, which soon came into widespread  use. He improved the Bessemer process for making steel, and he was the  first to survey British iron ores. At London�s Metropolitan School of Sci�  ences, he trained a generation of metallurgists. His multi volume Treatise  on Metallurgy (1861-80), though unfinished, quickly attained classic sta�  tus.</p><p>Percy, Walker (b. May 28, 1916, Birmingham, Ala., U.S.�d. May  10, 1990, Covington, La.) U.S. novelist. He was orphaned in late child�  hood and was raised by a cousin in Mississippi. While working as a  pathologist he contracted tuberculosis; during his recuperation he decided  on a writing career and converted to Roman Catholicism. His first and  best-known novel, The Moviegoer (1961), introduced his concept of mal�  aise, a sense of spiritual emptiness characteristic of the rootless modern  world. His other works, often about the search for faith and love in a New  South transformed by industry and technology, include Love in the Ruins  (1971), The Second Coming (1980), and The Thanatos Syndrome (1987).</p><p>Samuel Pepys, oil painting by John  Hayls, 1666; in the National Portrait  Gallery, London.</p><p>COURTESY OF THE NATIONAL PORTRAIT GALLERY,  LONDON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1472 I peregrine falcon &#x25BA; performance art</p><p>peregrine falcon Vper-o-groM or duck hawk Falcon species  (Falco peregrinus) found worldwide  but rare today because of bioaccumu�  lation of pesticides. Peregrines are  13-19 in. (33-48 cm) long and gray  above, with black-barred whitish  underparts. They fly high and dive at  tremendous speed (up to 175 mph, or  280 kph�the greatest speeds  attained by any bird), striking with  clenched talons and killing by  impact. They usually nest in a scrape  on a high cliff ledge near water,  where bird prey is plentiful. Breeding  programs have reintroduced the spe�  cies into the wild and introduced it  into urban areas, where it finds a cliff�  like habitat among skyscrapers and  preys chiefly on the rock dove (see  pigeon).

Per�  elman attended Brown University and soon began writing screenplays for  early Marx Brothers films such as Monkey Business (1931) and Horse  Feathers (1932). A master of wordplay, he regularly contributed essays  to The New Yorker, many were collected in books such as Westward Ha!  (1948) and The Road to Miltown (1957). He collaborated with Kurt Weill  on the musical One Touch of Venus (1943). His later screenplays include  Around the World in 80 Days (1956, Academy Award).</p><p>perennial Any plant that persists for several years, usually with new  herbaceous growth from a part that survives from season to season. Trees  and shrubs are perennial, as are some herbaceous flowers and vegetative  ground covers. Perennials have only a limited flowering period, but with  maintenance throughout the growing season, they provide a leafy pres�  ence and shape to the garden landscape. Popular flowering perennials  include bellflowers, chrysanthemums, columbines, lockspurs, hollyhocks,  phlox, pinks, poppies, and primroses. See also annual, biennial.</p><p>Peres \'per-es\, Shimon orig. Shimon Perski (b. Aug. 16, 1923,  Wotozyn, Pol.) Polish-born Israeli statesman. He immigrated to Palestine  _ with his family in 1934 and joined the Haganah organization in 1947. After</p><p>Israel achieved independence, he held a number of positions in the defense  jm establishment (1948-65). In 1968 he helped establish the Israel Labour</p><p>M Party. The indecisive 1984 election led to a power-sharing arrangement</p><p>with Likud candidate Yitzhak Shamir, the two men alternating as prime min�  ister. During Peres�s tenure (1984-86), Israel withdrew from most of Leba-  9 non. He was foreign minister under Yitzhak Rabin (1992-95); Peres, Rabin,</p><p>and Palestinian leader Yasir �Arafat shared the 1994 Nobel Prize for Peace.  Peres became prime minister again upon Rabin�s assassination in 1995 but  was narrowly defeated in his bid for reelection by Likud leader Benjamin  Netanyahu in 1996. Although Peres declined to seek reelection as leader of  the Labour Party in 1997, he later served as foreign minister (2001-02),  deputy prime minister (2001-02), and vice prime minister (2005) in the  national unity government led by Likud�s Ariel Sharon. In 2003 Peres  resumed the chair of the Labour Party but was unexpectedly defeated in the  party�s leadership election in 2005. He subsequently left the Labour Party.</p><p>perestroika \,per-3-'str6i-k9\ Russian "restructuring" Program  instituted in the Soviet Union by Mikhail Gorbachev in the mid-1980s to  restructure Soviet political and economic policy. Gorbachev proposed  reducing the direct involvement of the Communist Party leadership in the  country�s governance and increasing the local governments� authority.  Seeking to bring the Soviet Union up to economic par with capitalist  countries such as Germany, Japan, and the U.S., he decentralized eco�  nomic controls and encouraged enterprises to become self-financing. The  economic bureaucracy, fearing loss of its power and privileges, obstructed  much of his program.</p><p>Peretz \'per-ets\, l(saac) L(eib) or Yitskhok Leybush Perets (b.</p><p>May 18, 1852, or May 20, 1851, Zamosc, Pol., Russian Empire�d. April  3, 1915, Warsaw) Polish writer. Peretz wrote prolifically, mostly in Yid�  dish, bringing to the language both a new expressive force and modern�  izing influences from western European art and literature. His tales of  Hasidic lore (e.g., the Silent Souls series) are elegiac meditations on tra�  ditional values that draw material from the lives of impoverished eastern  European Jews. Among his works are story collections, including Folk�  tales (1908), the drama The Golden Chain (1909), and articles on many  subjects to encourage Jews toward wider secular knowledge.</p><p>Perez (Rodriguez), Carlos (Andres) (b. Oct. 27, 1922, Rubio,  Venez.) President of Venezuela (1974-79, 1989-93). He began his politi�  cal career at age 18. A founder of Democratic Action, he was elected  president in 1973 with the support of the liberal Romulo Betancourt. He  nationalized the oil industry while retaining experienced foreign person�  nel to ensure efficiency, slowed production to conserve resources, stimu�  lated small business and agriculture, and channeled petroleum income into  hydroelectric projects, education programs, and steel mills. Reelected in  1989, Perez promoted free-market economic reforms. After surviving two  attempted coups, he was imprisoned in 1993 on charges of embezzlement  and misuse of public funds.</p><p>Perez de Cuellar \'per-es-tha-'kwa-yar\, Javier (b. Jan. 19, 1920,  Lima, Peru) Fifth secretary-general of the United Nations (1982-91). He  joined the Peruvian foreign ministry in 1940 and its foreign service in  1944, serving in France, Britain, Bolivia, and Brazil. After serving as  ambassador to Switzerland and as Peru�s first ambassador to the Soviet  Union, he was appointed the country�s ambassador to the UN, a post he  held until he was appointed secretary-general. As secretary-general he  advocated the use of the United Nations Security Council for keeping the  peace and as a forum for negotiation. In his second term, he negotiated  the cease-fire that ended the Iran-Iraq War (1988). Perez de Cuellar later  served as prime minister of Peru (2000-01).</p><p>Perez Galdos \ , pa-rath-gal-'dos\, Benito (b. May 10, 1843, Las Pal�  mas, Canary Islands, Spain�d. Jan. 4, 1920, Madrid) Spanish novelist.  In the 1870s he began a cycle of 46 short historical novels, Episodios  nacionales (1873-1912), that earned him comparison with Honore de  Balzac and Charles Dickens. Some of his finest works chronicle contem�  porary Spain, including The Disinherited Lady (1881) and his master�  piece, Fortunata y Jacinta (1886-87), a study of two unhappily married  women. His earlier works show a reforming zeal and anticlericalism, but  after the 1880s he displayed greater sympathy for Spain and its idiosyn�  crasies, as in Nazarin (1895), Compassion (1897), and a series featuring  the character Torquemada. He also wrote plays, some very popular but of  less artistic value. He was regarded as Spain�s greatest novelist since  Miguel de Cervantes.</p><p>Perez Jimenez Vper-ez-he-'men-ezX, Marcos (b. April 25, 1914,  Michelena, Venez.�d. Sept. 20, 2001, Madrid, Spain) Soldier and presi�  dent of Venezuela (1953-58). He graduated from the Venezuelan Military  Academy and in 1945 and 1948 participated in coups d�etat. Appointed  to the presidency by the military and elected in 1953 by the constituent  assembly, which he controlled, he embarked on a program of vast public  works. He and his associates received commissions on every project. His  regime was marked by extravagance, corruption, police oppression,  unemployment, and high inflation. He was forced out of office in 1958  and later jailed for embezzling government funds. His repeated attempts  to reenter political life were thwarted.</p><p>perfect gas or ideal gas Gas whose physical behaviour conforms to  the general gas law, which states that for a given quantity of gas, the  product of the volume V and pressure P is proportional to the absolute  temperature T, or PV = kT, where k is a constant. A perfect gas is assumed  to consist of a large number of molecules in random motion, which obey  Newton's laws of motion. Their volume is assumed to be negligibly small,  and no forces are presumed to act on the molecules except during momen�  tary collisions. Though no gas has these properties, real gases at suffi�  ciently high temperatures and low pressures can be described this way.</p><p>performance art Art form that arose in Europe and the U.S. in the  1960s. The term describes an art that is live but operates outside the tra�  ditional conventions of theatre or music.

Perfumes are concocted by the art�  ful blending of certain fragrant substances in appropriate proportions. The  art of perfumery was apparently known to the ancient Chinese, Hindus,  Egyptians, Israelites, Carthaginians, Arabs, Greeks, and Romans; refer�  ences to perfumes are found in the Bible. Raw materials used in perfum�  ery include natural products, of plant or animal origin, and synthetic  materials. Fine perfumes may be blends of more than 100 ingredients.</p><p>perfume bottle Vessel made to hold scent. The earliest example is  Egyptian and dates to c. 1000 bc. The fashion for perfume later spread to  Greece, where terra-cotta and glass containers were made in a variety of  shapes such as animals and human heads. Romans made perfume bottles  out of molded and blown glass. The spread of Christianity marked a  decline in perfume production, as well as of glassmaking. The revival of  perfume making in France in the 12th century and the popularity of Vene�  tian gass in the 13th century revived the production of perfume bottles.</p><p>Pergamum Vpor-go-momX Greek Pergamon Vpsr-gs-mosV Ancient  Greek city, western Anatolia, near the modern town of Bergama, Turkey. It  existed from at least the 5th century bc but became important in the Helle�  nistic period when it was the residence of the Attalid dynasty and reached  its height (263-133 bc). Then it was bequeathed to Rome. After the fall of  Rome, it was ruled by the Byzantine Empire until it passed into Ottoman  hands in the early 14th century ad. It is one of the most outstanding  examples of city planning in antiquity, and its library was excelled only by  that at Alexandria, Egypt. Excavations begun in 1878 by the German  archaeologists unearthed many artistic treasures, including the great altar  of Zeus, which are now housed in Berlin�s Pergamon Museum.</p><p>pergola Vpsr-gs-lsN Garden walk or terrace typically formed by two  rows of columns or posts roofed with an open framework of beams and  cross rafters over which plants are trained. Its purpose is to provide a foun�  dation on which climbing plants can be viewed and to give shade.

They had a marked  revival during the Arts and Crafts Movement in Britain. See also arbor.</p><p>Pergolesi V.par-go-'la-zeV Giovanni Battista (b. Jan. 4, 1710, Jesi,  Italy�d. March 16, 1736, Pozzuoli) Italian composer. In 1732 he was  appointed chapel master to a Neapolitan prince. His comic opera Lofrate  �nnamorato (1732) was followed in 1733 by an opera seria, which had a  comic intermezzo that became his best-known work, La serva padrona.  His health failing, he moved into a Franciscan monastery (1736), where he  wrote his famous Stabat Mater and Salve Regina before dying at age 26.  Traveling opera troupes took up La serva padrona, and in 1752 the success  of a Paris production set off the controversy known as the guerre des bouf-  fons (�war of the buffoons�), with musical forgers vying to produce spu�  rious works of Pergolesi, leaving some uncertainty about the authenticity  of works attributed to him.</p><p>Periander \,per-e-'an-d9r\ (d. c.</p><p>587 bc) Second tyrant of Corinth (c.</p><p>627-587). He was the son of Cypse-  lus, founder of the Cypselid dynasty.</p><p>One of the most violent of the early  Greek tyrants, he killed his wife and  avenged the death of his son in Cor-  cyra by sending 300 Corcyran boys  to be castrated (they managed to  escape). He treated the nobility  harshly but built a strong, prosperous  Corinthian economy. His extensive  building program included construc�  tion of the Diolkos, a portage used to  transport ships across the Isthmus of  Corinth.</p><p>Pericles \'per-9-,klez\ (b. c. 495,</p><p>Athens�d. 429 bc, Athens) Athenian  general and statesman largely  responsible for the full development</p><p>of Athenian democracy and the Athe�  nian empire. Related to the influential  Alcmaeonid family, he was elected to  power sometime after 461, and he  quickly helped adopt essential demo�  cratic reforms. He asserted Athenian  control over the Delian League and  used the league�s treasury to rebuild  the Acropolis, which had been sacked  by the Persians. His influential con�  sort Aspasia bore him a son, who was  legitimated when his legitimate sons  died. In 447�446 Athens lost Megara,  giving Sparta direct access to Attica.</p><p>Though Athens and Sparta agreed on  a Thirty Years� Peace (446-445), Per�  icles had the Long Walls from Athens  to the port at Piraeus strengthened for  protection. When war broke out in  431, he relied on the navy to keep the  city supplied. Attica�s population  was brought inside the Long Walls,  leaving the countryside open to Spartan pillaging. When plague broke out,  killing one-fourth of the population, he was deposed and fined. He was  reelected, but he too died of the plague. His great funeral oration (c. 430)  remains one of the greatest defenses of democracy, and his era is remem�  bered as the Golden Age of Athens.</p><p>peridot \'per-9-.dat, 'per-9-,do\ or precious olivine Va-l9-,ven\ Gem-  quality, transparent green olivine. Very large crystals are found in Myan�  mar; peridots from the U.S. are seldom larger than two carats.

He  was elected to the French Chamber of Deputies (1817), where he opposed  Charles X. After the July Revolution of 1830 made Louis- Philippe king, Perier  became premier (1831) and quickly restored civic order in France. Active  in foreign affairs, he sent an army to defend Belgium against the Dutch  (1831) and ordered the occupation of Ancona to check Austrian predomi�  nance in the Papal States (1832). His authoritarian approach brought  attacks from both left and right and sometimes alienated the king.</p><p>Perigord \,pa-re-'g6r\ Historic and cultural region, southern France.

After it was  inherited by the crown of Navarra, Henry IV united it with the French  crown in 1607.</p><p>period In geology, the basic unit of the geologic time scale. During these  spans of time, specific systems of rocks were formed. Originally, the  method for defining the sequence of periods was relative; it was based on  stratigraphy and paleontology. Carbon- 14 dating and similar methods are  now used to determine absolute ages for various periods.</p><p>periodic motion Motion that is repeated in equal intervals of time.  The time of each interval is the period. Examples of periodic motion  include a rocking chair, a bouncing ball, a vibrating guitar string, a swing�  ing pendulum, and a water wave.

In the 20th century, when the structure  of atoms was understood, the table was seen to precisely reflect increas�  ing order of atomic number. Members of the same group in the table have  the same number of electrons in the outermost shells of their atoms and  form bonds of the same type, usually with the same valence; the noble  GAS es, with full outer shells, generally do not form bonds. The periodic  table has thus greatly deepened understanding of bonding and chemical  behaviour. It also allowed the prediction of new elements, many of which  were later discovered or synthesized. For an illustration of the periodic  table, see chemical element.</p><p>periodical Publication whose issues appear at fixed or regular inter�  vals. Periodicals generally are considered to include newspapers, which  usually have large, unfastened pages and contents with considerable  immediacy; and magazines, or journals, which have smaller pages, are  usually fastened or bound, and often have more specialized, less time-  dependent contents.</p><p>periodontitis V.per-e-o-.dan-'tl-tosX Inflammation of soft tissues around  the teeth (see tooth). Poor dental hygiene leads to deposition of bacterial  plaque on the teeth below the gum line, irritating and eroding nearby tis�  sues. If it is not treated, the gum margin recedes, exposing the roots of  the teeth. The process eventually involves the bone anchoring the teeth,  which loosen and may fall out. Removal of all plaque deposits and  affected soft tissues can arrest but not reverse bone deterioration.</p><p>periosteum V.per-e-'as-te-omN Dense membrane over bones. The outer  layer contains nerve fibres and many blood vessels, which supply cells in  the bone. The bone-producing cells of the inner layer are most prominent  in fetal life and early childhood, when bone formation is at its peak. In  adulthood they are less active but vital to continuous bone remodeling.  When bone is injured, they multiply profusely to produce new bone.</p><p>periscope Optical instrument (see optics) used in land and sea warfare,  submarine navigation, and elsewhere to enable an observer to see the sur�  roundings while remaining under cover, behind armour, or submerged. A  periscope includes two mirrors or reflecting prisms to change the direction  of the light coming from the scene observed: the first deflects it down  through a vertical tube, the second diverts it horizontally so that the scene  can be viewed conveniently.</p><p>peristalsis \,per-9-'st6l-s9s\ Progressive wavelike muscle contractions in  the esophagus, stomach, and intestines, and sometimes in the ureters and  other hollow tubes. The waves can be short, local reflexes or long, con�  tinuous contractions along the length of the organ. In the esophagus, peri�  staltic waves push food into the stomach. In the stomach, they help mix  stomach contents and propel food to the small intestine, where they expose  food to the intestinal wall for absorption and move it forward. Peristalsis  in the large intestine pushes waste toward the anal canal and is important  in removing gas and dislodging potential bacterial colonies.</p><p>I peritonitis \,per-3-t 3 n-'i-t3s\ Inflammation of the peritoneum (see abdomi-</p><p>m nal cavity), with pus accumulating between the parietal and the visceral</p><p>peritoneum, abdominal pain and distension, vomiting, and fever. It may  be acute or chronic, local or generalized. Acute peritonitis usually results  m from inflammation elsewhere (e.g., by spread of bacterial infection). Pri�  ll mary peritonitis often comes from a perforated gastrointestinal tract, as</p><p>with rupture in appendicitis. Control of the source problem may be fol�  lowed by remission, adhesions, or abscesses (much rarer since the devel�  opment of antibiotics).</p><p>periwinkle In botany, any of various plants of the genus Vinca of the  dogbane family. The lesser periwinkle (U minor), which has small lilac-  blue flowers, is a dependable, trailing, evergreen perennial that is native  to Europe and has become widespread over much of eastern North  America. The greater periwinkle (U major), with larger leaves and larger  purplish-blue flowers, is native to continental Europe and has become  naturalized in England. Alkaloids derived from the periwinkle plant have  had some success in inhibiting cancer growth.</p><p>periwinkle In zoology, any of some 80 species (family Littorinidae) of  widely distributed, chiefly herbivorous shore SNAILS. Periwinkles are usu�  ally found on rocks, stones, or pilings between high- and low-tide marks.  The common periwinkle ( Littorina littorea), the largest northern species,  may grow to 1.5 in. (4 cm) long. It is usually dark gray and has a solid  spiral shell. Introduced into North America c. 1857, it is now common on  Atlantic coasts. All periwinkle species are a favourite food of many shore-  birds. See photograph above.</p><p>Periyar \,per-i-'yar\ River River,  central Kerala state, southwestern  India. It is 140 mi (225 km) long and  rises in the Western Ghats range near  the border with Tamil Nadu state. It  flows north to Periyar Lake, an arti�  ficial reservoir created by damming  the river. A tunnel carries water from  the lake eastward through the moun�  tains to the Vaigai River, where it is  used for irrigation. From the lake it  flows northwest and empties into the  Arabian Sea.</p><p>perjury In law, act or crime of  knowingly making a false statement  while under oath. The statement  must be material to the issue of inquiry. Perjuries that have the effect of  obstructing the adjudication of a case may be given increased punishment  for that reason. A person who makes a false statement and later corrects  it is usually not considered to have committed perjury.</p><p>Perkins, Anthony (b. April 4, 1932, New York, N.Y., U.S.�d. Sept.  12, 1992, Hollywood, Calif.) U.S. film actor. He was the son of the actor  Osgood Perkins, and he studied at Columbia University. After making his  screen debut in The Actress (1953), he appeared in films such as Friendly  Persuasion (1956) and Fear Strikes Out (1957), but he was best known  as the murderous motel owner Norman Bates in Alfred Hitchcock�s Psy�  cho (1960). He later appeared in several films in Europe, including The  Trial (1963), The Champagne Murders (1967), and Ten Days� Wonder  (1972), and in U.S. films such as Pretty Poison (1968), Catch-22 (1970),  and WUSA (1970).

From 1929 to  1933 she served as state industrial commissioner under New York Gov.  Franklin D. Roosevelt. As president, Roosevelt appointed her U.S. secretary  of labor; she thereby became the first woman to hold a U.S. cabinet post. In  her long term of office (1933�45) she advocated reforms such as a minimum  wage, a maximum workweek, and unemployment compensation; she also  helped draft the Social Security Act and supervised the Fair Labor Standards  Act (1938). She was later a U.S. Civil Service commissioner (1945-53).</p><p>Perkins, Jacob (b. July 9, 1766, Newburyport, Mass., U.S.�d. July  30, 1849, London, Eng.) U.S. inventor. He built a machine to cut and  head nails in one operation c. 1790. He developed a method of engraving  paper money that made counterfeiting difficult; lack of interest in the U.S.  led him to set up a bank-note factory in England (1819). He experimented  with high-pressure steam boilers, built a horizontal steam engine (1827),  designed an improved paddle wheel (1829), and invented a means for the  free circulation of water in boilers (1831) that led to the design of mod�  ern water-tube boilers.</p><p>Perkins, Maxwell (Evarts) (b.

Despite a bout with polio at age four that left his legs para�  lyzed, he was a prodigy, and he made his U.S. television debut at age 13.  He studied with Ivan Galamian and Dorothy DeLay at Juilliard. Recog�  nition of his gifts led to a highly successful career as orchestral soloist  and chamber-music player, with scores of recordings. Blessed with a  popular touch, he appeared on television, played jazz and klezmer music,  and involved himself in educating young musicians.</p><p>permafrost Perennially frozen earth, with a temperature below 32 �F  (0 �C) continuously for two years or more. Permafrost is estimated to  underlie 20% of the Earth�s land surface and reaches depths of 5,000 ft  (1,500 m) in northern Siberia. It occurs in 85% of Alaska, more than half  of Russia and Canada, and probably all of Antarctica. Permafrost has a  significant effect on plant and animal life, and it presents special prob�  lems in engineering projects. All land use in permafrost environments  must take into account the terrain�s special sensitivity; if the delicate  natural balance is not maintained, extensive degradation and ecological  damage may result.</p><p>permeability, magnetic See magnetic permeability</p><p>Permian Period Interval of geologic time, 290-248 million years ago.  The last of the six periods of the Paleozoic Era, it follows the Carbonif�  erous Period. During the Permian, the continents joined to form a single  supercontinent, Pangea. Hot, dry conditions prevailed almost everywhere,  and deserts were widespread. Life evolved as a continuation of established  lines. Marine invertebrates evolved into several lineages. Marine and  freshwater fish and amphibians thrived. Reptiles evolved into three dis�  tinct groups: the cotylosaurs, the pelycosaurs, and the therapsids. Land  plants evolved from ferns and seed ferns to conifers and adapted to drier  and well-drained land conditions. Toward the close of the Permian, many  forms of life suffered mass extinction, whose causes are unknown.</p><p>permutations and combinations Number of ways a subset of  objects can be selected from a given set of objects. In a permutation, order  is important; in a combination, it is not. Thus, there are six permutations  of the letters A, B, C selected two at a time (AB, AC, BC, BA, CA, CB)  yet only three combinations (AB, AC, BC). The number of permutations  of r objects chosen from a set of n objects, expressed in factorial nota�  tion, is n\ -j- (n - r)! The number of combinations is n\ 4 [r(n - r)!]. The  (r + l)st coefficient in the binomial expansion of (x + y) n coincides with  the combination of n objects chosen r at a time (see binomial theorem).  Probability theory evolved from the study of gambling, including figuring  out combinations of playing cards or permutations of win-place-show  possibilities in a horse race, and such counting methods played an impor�  tant role in its development in the 17th century.</p><p>Pernambuco See Recife</p><p>pernicious anemia Slow-developing disease in which vitamin B 12  (see vitamin B complex) deficiency impairs red-blood-cell production.

Born into poverty, she was an actress  when she married Peron. She was instrumental in the success of his first  presidential campaign and won the adulation of the masses. Evita acted  as de facto minister of health and labour, awarding generous wage  increases to workers. With �voluntary� contributions from businesses.</p><p>labour unions, and the elite, she established thousands of hospitals,  schools, and orphanages.

They married  during his exile in 1961, and she became his running mate in the 1973  presidential election. She succeeded him when he died in 1974, inherit�  ing problems of inflation and political violence, which she tried�  ineffectively�to solve by printing money and imposing a state of siege.  She was deposed in 1976; after five years of house arrest, she was con�  victed of corruption but permitted to go into exile in Spain.</p><p>Peron, Juan (Domingo) (b. Oct. 8, 1895, Buenos Aires province,  Arg.�d. July 1, 1974, Buenos Aires) President of Argentina (1946-55,  1973-74). After attending military school, he served in the 1930s in Italy,  where he observed the successes of the Fascists. In 1943 he helped over�  throw Argentina�s ineffective civilian government. As secretary of labour  and social welfare, he built a loyal following among industrial workers,  who helped elect him president in 1946. Peron�s political views drew on  both the far left and the far right: while he showered workers with much-  needed benefits, he restricted civil liberties severely. The charisma of his  second wife, Eva Peron, greatly increased the regime�s standing with the  populace. He was reelected in 1951, but a disastrous economic decline  and increasing disaffection among many elements of Argentine society  led to his overthrow in 1955 by democratically inspired military officers.  He lived in exile in Spain for two decades but continued to influence  Argentine affairs. When the Peronist party was made legal, he was  reelected president in absentia; he died less than a year after returning to  Argentina and assuming the presidency.

He worked for IBM from 1957 to 1962,  when he formed his own company, Electronic Data Systems; he sold it  in 1984 to General Motors for $2.5 billion. In 1992 he became an inde�  pendent candidate for U.S. president. Appealing to voters dissatisfied with  traditional party politics, he won 19% of the popular vote, the best third-  party presidential showing since 1912. He ran again in 1996 but received  only 8% of the vote. His Reform Party, which he founded in 1995, gradu�  ally established its autonomy from him.</p><p>peroxide Any of a class of chemical compounds in which two oxygen  atoms are linked by a single covalent bond.

The style, con�  cerned with creating rich visual effects through decoration, was charac�  terized by a predominance of vertical lines in stone window tracery,  enlargement of windows to great proportions, and conversion of the inte�  rior stories into a single unified vertical expanse. Fan vaults, springing  from slender columns or pendants, became popular. The oldest surviving  example of the style is probably the choir of Gloucester Cathedral (begun  c. 1335). Other major monuments include King�s College Chapel, Cam�  bridge (1446-1515), and the chapel of Henry VII in Westminster Abbey. In  the 16th century, the grafting of Renaissance elements onto the Perpen�  dicular style resulted in the Tudor style.</p><p>Perpignan \,per-pe-'nya n \ City (pop., 1999: 105,115), southern France.

He led naval forces in the  Mexican War and assisted Winfield  Scon at Veracruz. In 1852 Pres. Mill�  ard Fillmore sent Perry to head a  naval expedition to induce Japan to  establish diplomatic relations with  the U.S. Concluding that the coun�  try�s centuries-old policy of isolation would be ended only by a show of  force, Perry led four ships into the fortified harbour of Uraga (1853) and  convinced the Japanese to accept his message. In 1854 he entered Edo  (now Tokyo) Bay with nine ships and concluded the first treaty between  Japan and the U.S., which granted the U.S. trading privileges and opened  the Far East to U.S. influence.</p><p>Jules Perrot, engraving after a draw�  ing.</p><p>Perry, Oliver Hazard (b.

The United States, fearing Iraq�s broader strategic intentions  and acting under UN auspices, eventually formed a broad coalition, which  included a number of Arab countries, and began massing troops in north�  ern Saudi Arabia. When Iraq ignored a UN Security Council deadline for  it to withdraw from Kuwait, the coalition began a large-scale air offen�  sive (Jan. 16-17, 1991). Saddam responded by launching ballistic mis�  siles against neighbouring coalition states as well as Israel. A ground  offensive by the coalition (February 24-28) quickly achieved victory.  Estimates of Iraqi military deaths range up to 100,000; coalition forces  lost about 300 troops. The war also caused extensive damage to the  region�s environment. The Iraqi regime subsequently faced widespread  popular uprisings, which it brutally suppressed. A UN trade embargo  remained in effect after the end of the conflict, pending Iraq�s compliance  with the terms of the armistice. The foremost term was that Iraq destroy  its nuclear-, biological-, and chemical-weapons programs. The embargo  continued into the 21st century and ceased only after the Second Persian  Gulf War.</p><p>Persian Gulf War, Second (2003) International conflict that took  place between Iraq and a combined force of troops from the United States  and Great Britain, with smaller contingents from several other countries.  The trade embargo and weapons-inspection process that the UN imposed  on Iraq following the First Persian Gulf War (1990-91) had partly fallen  into abeyance by 2001. U.S. Pres. George W. Bush argued that the Sep�  tember 11 attacks on the U.S. in that same year highlighted the threat to  U.S. security posed by hostile countries such as Iraq. Encouraged by Bush  and British Prime Minister Tony Blair, the UN issued Security Council  Resolution 1441 in November 2002, demanding that Iraq readmit weap�  ons inspectors and comply with all previous resolutions. Although Iraqi  did readmit inspectors, Bush and Blair declared in early 2003 (despite  objections by many world leaders) that Iraq was continuing to hinder UN  inspections and that it still retained proscribed weapons. On March 20,  seeking no further UN resolutions, the U.S. and Britain (with token rep�  resentation from other countries) launched a series of air attacks on Iraq,  and a ground invasion followed. Iraqi military and paramilitary forces  were rapidly defeated; on April 9 U.S. forces took control of the capital,  Baghdad, and British forces completed their occupation of the southern  city of AI-Basrah the same day. Within a few more days, all major cities  had fallen, and by May 1 major combat operations had been completed.  Guerrilla assaults on occupying forces continued thereafter, hindering  Iraq�s recovery.</p><p>Persian language or Farsi language Iranian language spoken by  more than 25 million people in Iran as a first language, and by millions  more as a second. Modern Persian is a koine developed from southwest�  ern dialects in the 7th-9th centuries, after the introduction of Islam  brought a massive infusion of loanwords from Arabic. Its standardization  and literary cultivation took place in northeastern Persia and Central Asia  in the 11 th� 12th centuries. Polities outside Persia itself (e.g., Mughal</p><p>India, Ottoman Turkey) have at times been major literary centres. Its sta�  tus in those countries led to a very strong Persian influence on Urdu and  Ottoman Turkish. Other Turkic and Indo-Aryan languages, Caucasian lan�  guages, and Iranian languages have also borrowed heavily from Persian.  It is written in a slightly modified form of the Arabic alphabet.</p><p>Persian Wars or Greco-Persian Wars (492-449 bc) Series of  wars between Greek states and Persia, particularly two invasions of  Greece by Persia (490, 480-479). When Darius I came to power in Persia  in 522, the Ionian Greek city-states in Anatolia were under Persian con�  trol. They rose up unsuccessfully in the Ionian revolt (499-494). The sup�  port lent by Athens provoked Darius to invade Greece (492). His fleet  was destroyed in a storm. In 490 he assembled a huge army on a plain  near Athens; his devastating defeat at the Battle of Marathon sent him  back to Persia. In 480 the Persians under Xerxes I again invaded Greece,  seeking to avenge the defeat. This time all Greece fought together, with  Sparta in charge of the army and Athens of the navy. A band of Spartans  under Leonidas was overcome at the Battle of Thermopylae, allowing the  Persian army to reach Athens, which they sacked (480). When the Per�  sian navy was soundly defeated at the Battle of Salamis, Xerxes withdrew  it to Persia. His army was defeated at the Battle of Plataea in 479 and  driven from Greece, and the navy met a similar fate at Mycale on the  Anatolian coast. Sporadic fighting went on for 30 more years, during  which Athens formed the Delian League to free the Ionians. The Peace of  Callias (449) ended the hostilities.</p><p>persimmon Either of two trees of  family, and their globular, edible  fruits.

A typical PC assemblage comprises a CPU; internal  memory consisting of RAM and ROM; data storage devices (including a  hard disc, a floppy disc, or CD-ROM); and input/output devices (including  a display screen, keyboard, mouse, and printer). The PC industry began in  1977 when Apple Computer introduced the Apple II. Radio Shack and  Commodore Business Machines also introduced PCs that year. IBM  entered the PC market in 1981. The IBM PC, with increased memory  capacity and backed by IBM�s large sales organization, quickly became  the industry standard. Apple�s Macintosh (1984) was particularly useful  for desktop publishing. Microsoft Corp. introduced MS Windows (1985), a  graphical user interface that gave PCs many of the capabilities of the  Macintosh, initially as an overlay of MS-DOS. Windows went on to  replace MS-DOS as the dominant operating system for personal comput�  ers. Uses of PCs multiplied as the machines became more powerful and  application software proliferated. Today, PCs are used for word process�  ing, Internet access, and many other daily tasks.</p><p>personal-liberty laws Laws passed by U.S. states in the North to  counter the Fugitive Slave Acts. Such states as Indiana (1824) and Con�  necticut (1828) enacted laws giving escaped slaves the right to jury trials  on appeal. Vermont and New York (1840) assured fugitives the right of  jury trial and provided them with attorneys. Other states forbade state  authorities to capture and return fugitives. After the Compromise of 1850,  most Northern states enacted further guarantees of jury trials and punish�  ment for illegal seizure. These laws were cited by proslavery interests as  assaults on states� rights and as justification for secession.</p><p>personal property See real and personal property</p><p>personalismo Spanish "personalism" In Latin America, the prac�  tice of glorifying a leader.

Personality embraces a person�s moods, attitudes, opinions,  motivations, and style of thinking, perceiving, speaking, and acting. It is  part of what makes each individual distinct. Theories of personality have  existed in most cultures and throughout most of recorded history. The  ancient Greeks used their ideas about physiology to account for differences  and similarities in temperament. In the 18th century Immanuel Kant, Charles-  Louis Montesquieu, and Giambattista Vico proposed ways of understanding  individual and group differences; in the early 20th century Ernst Kretschmer  and the psychoanalysts Sigmund Freud, Alfred Adler, and Carl Jung offered  competing personality theories. Freud�s model rested on the power of psy-  chosexual drives as mediated by the structural components of the ID, EGO,  and superego and the interplay of conscious and unconscious motives. Par�  ticularly important was the array of defense mechanisms an individual  employed. Jung, like Freud, emphasized unconscious motives but  de-emphasized sexuality and advanced a typal theory that classified people  as introverts and extraverts; he further claimed that an individual personal�  ity was a persona (i.e., social facade) drawn from the �collective uncon�  scious,� a pool of inherited memories. Later theories by Erik H. Erikson,  Gordon W. Allport, and Carl R. Rogers were also influential. Contempo�  rary personality studies tend to be empirical (based on the administration of  projective tests or personality inventories) and less theoretically sweeping  and tend to emphasize personal identity and development. Personality  traits are usually seen as the product of both genetic predisposition and  experience. See also personality disorder; psychological testing.</p><p>personality disorder Mental disorder that is marked by deeply  ingrained and lasting patterns of inflexible, maladaptive, or antisocial  behaviour to the degree that an individual�s social or occupational func�  tioning is impaired. Rather than being illnesses, personality disorders are  enduring and pervasive features of the personality that deviate markedly  from the cultural norm. They include the dependent, histrionic, narcissis�  tic, obsessive-compulsive, antisocial, avoidant, borderline (unstable),  paranoid, and schizoid types. The causes appear to be both hereditary and  environmental. The most effective treatment combines behavioral and  psychotherapeutic therapies (see behaviour therapy; psychotherapy).</p><p>personnel administration See industrial relations</p><p>perspective Depiction of three-dimensional objects and spatial rela�  tionships on a two-dimensional plane. In Western art, illusions of volume  and space are generally created by use of the linear perspective system,  based on the observation that objects appear to shrink and parallel lines  to converge at an infinitely distant vanishing point as they recede in space  from the viewer. The vanishing point may have been known to the Greeks  and Romans but had been lost until Filippo Brunelleschi rediscovered the  principles of linear or �mathematical� perspective early in the 15th cen�  tury. Linear perspective dominated Western painting until the late 19th  century, when Paul Cezanne flattened the conventional picture plane. The  Cubists and other 20th-century painters abandoned depiction of three-  dimensional space altogether.

Human eccrine sweat is  essentially a dilute solution of sodium chloride with trace amounts of other  plasma electrolytes. In extreme conditions, human beings may excrete  several litres of such sweat in an hour.</p><p>Perth City (pop., 2004 est.: 1,457,639), capital of Western Australia state,  Australia. Located on the Swan River 10 mi (16 km) from its mouth, Perth  was settled in 1829. It developed rapidly after the discovery of goldfields  around Kalgoonie in the early 1890s and the opening of Fremantle Har�  bour in 1897. It is now a major industrial centre with a rapidly expand�  ing economy.

Located on the  River Tay, northwest of Edinburgh, Perth was a Roman settlement; it  became a royal burgh in 1210. It was the capital of Scotland until 1437,  when King James I of Scotland was murdered there. At the Church of St.  John the Baptist in 1559, John Knox denounced idolatry; the result was  the plunder of Perth�s monasteries and altars. It was a Jacobite city dur�  ing the Scottish uprisings of 1715 and 1745. The economy is based on  whisky blending and distilling and on manufacturing. It is also an agri�  cultural market centre.</p><p>pertussis See whooping cough</p><p>Peru officially Republic of Peru Country, western South America.  Area: 496,225 sq mi (1,285,216 sq km).

Peru is the  third largest country in South America and may be divided into three geo�  graphic regions from west to east: the coast, which consists of a long,  narrow belt of desert lowlands; the Sierra (highlands), which is the Peru�  vian portion of the Andes Mountains; and the Montana, the vast, forested  eastern foothills and plains, consisting mainly of the tropical rainforests  of the Amazon River basin. Peru has a developing mixed economy based  largely on services, manufacturing, agriculture, and mining. Most indus�  tries, including the petroleum industry, were nationalized in the late 1960s  and early �70s, but many were privatized again in the 1990s. Peru is a  republic with one legislative house; its head of state and government is  the president. Peru was the centre of the Inca empire, whose capital,  Cuzco, was established in the 12th century. In 1533 the region was con�  quered by Spanish adventurer Francisco Pizarro and thereafter was domi�  nated by Spain for almost 300 years as the Viceroyalty of Peru. It declared  its independence in 1821, and freedom was achieved in 1824. Peru was  defeated by Chile in the War of the Pacific (1879-83). In 1941 a bound�  ary dispute with Ecuador erupted into war, which gave Peru control over  a larger part of the Amazon basin; further disputes ensued until the bor�  der was demarcated again in 1998. The government was overthrown by  a military junta in 1968; civilian rule was restored in 1980. The govern�  ment of Alberto Fujimori dissolved the legislature in 1992 and promulgated  a new constitution the following year. The government later successfully  combated the Shining Path and Tupac Amaru rebel movements.

Founded in 1543, it initially  included most of South America, but it lost jurisdiction over much of its  territory to other viceroyalties over time. Peru, with its wealth of silver,  was considered Spain�s most valuable possession in the Americas. By the  late 18th century, Indian rebellions had destabilized the region, and the  viceroyalty was unable to defend itself when the revolutionary forces of  Jose de San Martin entered Lima in 1821. It became part of Peru and Chile  in 1824.

Perugia lies north of Rome between the Tiber River  and Lake Trasimeno. Founded by the Umbrians, it became one of the 12  major cities of the Etruscans; it later was ruled by Rome (from 310 bc).  It became a Lombard duchy in ad 592. It was the centre of the great  Umbrian school of painting, which flourished in the 15th century (see  Perugino; Pinturicchio). Perugia played an active role in the Italian Risorg-  imento and became part of Italy in 1860. It is an agricultural trade centre  noted for its chocolate. There are notable remains of buildings and for�  tifications from Etruscan and medieval times.</p><p>Perugino \,per-3-'je-no\ orig.

Born near Perugia (the  source of his nickname), he was probably a pupil of Piero della Francesca  and Andrea del Verrocchio. One of his most famous frescoes. Giving of  the Keys to St. Peter (1481-82), in the Sistine Chapel, anticipated High  Renaissance ideals in its compositional clarity and sense of spaciousness.  He was at the height of his powers c. 1490-1500, when he painted the  Crucifixion fresco for the convent of Santa Maria Maddalena dei Pazzi  in Florence. Perugino�s art declined in his later years, and c. 1505 he left  the highly critical Florentine art scene to work in Umbria. In 1508 he  made a brief comeback by painting roundels on the ceiling of the Stanza  dell�Incendio in the Vatican. The commission for the wall frescoes went  to his pupil Raphael, who had already proved himself the greater artist.</p><p>Vision of St. Bernard, wood panel by Perugino, c. 1491-94; in the Alte Pi na-  kothek, Munich.</p><p>COURTESY OF THE ALTE PINAKOTHEK, MUNICH</p><p>Perun \p y i-'run\ In ancient Slavic religion, the thunder god.

Invertebrate pests  include some protozoans, flatworms, nematodes, mollusks, arachnids, and  especially insects. Mammals and birds can also be pests. Human activi�  ties, such as monocultural farming practices, use of broad-spectrum pes�  ticides, and introduction of exotic species, often result in the proliferation  of pest species.

His teaching method emphasized group rather than indi�  vidual recitation and focused on such participatory activities as drawing,  writing, singing, physical exercise, model making, collecting, mapmak�  ing, and field trips. Among his ideas, considered radically innovative at  the time, were making allowances for individual differences, grouping  students by ability rather than age, and encouraging formal teacher train�  ing.</p><p>pesticide Any toxic substance used to kill animals or plants that dam�  age crops or ornamental plants or that are hazardous to the health of  domestic animals or humans.

Dogs are known to have been kept as pets since prehistoric times; cats,  since the 16th century bc; and horses, since at least 2000 bc. Other com�  mon pets include birds, rabbits, rodents, raccoons, reptiles, amphibians,  and even insects. The trend toward making pets of exotic animals (e.g.,  monkeys and ocelots) is worrisome because owners can rarely provide  for their needs, and the animals� already precarious populations are fur�  ther depleted when members are sold for pets.</p><p>PET See positron emission tomography</p><p>Petain \pa-'ta n \, (Henri-) Philippe (b.

His suc�  cessful defense in the Battle of Verdun (1916) made him a national hero,  and in 1918 he became commander in chief and a marshal of France. After  the war he was appointed vice president of the Supreme War Council  (1920-30) and minister of war (1934). After the German invasion of  France (1940), Petain was appointed premier at age 84. He concluded an  armistice with Germany, and as head of Vichy France he attempted to  obtain concessions by cooperating with the Germans. In 1942 the Ger�  mans forced him to accept Pierre Laval as premier and he withdrew to a  nominal role as head of state. After the Allied invasion of France, he fled  to Germany.

Early in his reign, Peter faced revolts by his brothers, which were  suppressed, and he also endured raids by the Magyars, who crossed Bul�  garia on their way to the Byzantine Empire. His reign, however, was gen�  erally peaceful, and he made important gains against the Byzantines,  receiving the title emperor from them. He also forced the Byzantines to  recognize the independence of the Bulgarian church, and he married the  granddaughter of the Byzantine emperor Romanus I Lecapenus. In 965 war  broke out with the Byzantines; Peter subsequently suffered a stroke and</p><p>W retired to a monastery, where he died two years later.

Interested in progressive  influences from western Europe, he visited several countries there (1697-  98). After returning to Russia, he introduced Western technology, mod�  ernized the government and military system, and transferred the capital  to the new city of St. Petersburg (1703). He further increased the power  of the monarchy at the expense of the nobles and the Orthodox church.  Some of his reforms were implemented brutally, with considerable loss  of life. Suspecting that his son Alexis was conspiring against him, he had  Alexis tortured to death in 1718. He pursued foreign policies to give Rus�  sia access to the Baltic and Black seas, engaging in war with the Otto�  man Empire (1695-96) and with Sweden in the Second Northern War  (1700-21). His campaign against Persia (1722-23) secured for Russia the  southern and western shores of the Caspian Sea. In 1721 he was  proclaimed emperor; his wife succeeded him as the empress Catherine I.  For raising Russia to a recognized place among the great European pow�  ers, Peter is widely considered one of the outstanding rulers and reform�  ers in Russian history, but he has also been decried by nationalists for  discarding much of what was unique in Russian culture, and his legacy  has been seen as a model for Joseph Stalin�s brutal transformation of Rus�  sian life.</p><p>Peter I (b.

The son of Prince Alexander Karadjordjevic, who  was forced to abdicate in 1858, he lived with his family in exile. He fought  with the French army in the Franco-Prussian War and with the Serbian  revolt against the Turks (1875). After the assassination of Alexander  Obrenovic (1903), Peter was elected king of Serbia. He advocated a con�  stitutional government and won recognition for his liberal policies.

Peter�s regency was directed by Alek�  sandr Menshikov. He fell under the influence of the aristocratic Dolgoruky  family, which ousted Menshikov as regent, moved the capital to Moscow  (1728), and arranged Peter�s betrothal to one of its princesses.

After a coup deposed Paul (1941), Peter ruled for sev�  eral weeks until the German invasion forced him to flee to London. He  led a government-in-exile until the Yugoslav monarchy was abolished in  1945. He moved to the U.S., where he worked in public relations.</p><p>Peter III Spanish Pedro known as Peter the Great (b. 1239�d.  Nov. 11, 1285, Villafrance del Panades, Catalonia) King of Aragon (1276-  85) and of Sicily (as Pedro I, 1282-85). He married the Hohenstaufen  heiress of Sicily (1262) and ended the Sicilian revolt (1282), becoming  king despite Guelph and papal opposition (see Sicilian Vespers). Unhappy  with his Sicilian venture, nobles and municipalities in Aragon forced Peter  to confirm their legal rights and to diminish crown rights. In 1285 he  defeated Philip III of France, who had invaded Aragon in an effort to  dethrone him.</p><p>Peter III Russian Pyotr Fyodorovich orig. Karl Peter Ulrich,  duke von Holstein-Gottorp (b. Feb. 21, 1728, Kiel, Holstein-  Gottorp�d. July 18, 1762, Ropsha, near St. Petersburg, Russia) Tsar of  Russia (1762). Grandson of Peter I, the young duke was brought to Rus�  sia by his aunt Elizabeth when she became empress (1741). Proclaimed the  heir to the Russian throne, he was unpopular at court for his pro-Prussian  attitude. After he succeeded Elizabeth (1762), he reversed her foreign  policy, making peace with Prussia and withdrawing from the Seven Years'  War. He offended the Orthodox church by trying to force it to adopt  Lutheran practices. After six months he was forced to abdicate by a group  of nobles, in collusion with his own wife, Catherine (later Catherine II),  and Count Grigory Orlov, and was murdered while in the conspirators�  custody.</p><p>Peter IV Spanish Pedro known as Peter the Cruel (b. Sept. 5, 1319,  or Sept. 15, 1317, Balaguer, Catalonia�d. Jan. 5, 1387, Barcelona) King  of Aragon (1336-87). He took the Balearic Islands and Roussillon from  Majorca (1343-44), defeated the Aragonese nobles (1348), and became  duke of Athens and Neopatras (1380). He waged war against Castile  (1356-66) but failed to gain any territory; after 1369 France favoured  Castile over Aragon. Peter tried to maintain neutrality in the Hundred  Years' War, and he quarreled with his heir, the future John I, who became  the tool of French intrigues.</p><p>Peter, Saint See Saint Peter the Apostle</p><p>Peter Damian Vda-me-3n\, Saint (b. 1007, Ravenna�d. Feb. 22,  1072, Faenze; feast day February 21) Italian cardinal and Doctor of the  Church. He was prior of Fonte Avellana in the Apennines before being  named a cardinal in 1057. A leading monastic reformer and ascetic, he  played an important role in the promotion of apostolic poverty and in sup�  port of papal reformers who sought to enforce clerical celibacy and abolish  simony. He defended Pope Alexander II against the antipope Honorius II and  reconciled Alexander with the city of Ravenna. He was also sent as a papal  legate to resolve disputes in Milan and Cluny, Burgundy, and he played a  key role in the formulation of the papal election decree of 1059.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Peter Lombard &#x25BA; petition I 1481</p><p>Peter Lombard (b. c. 1100, Novara, Lombardy�d. Aug. 21/22, 1160,  Paris) French bishop and theologian. He studied in Bologna and taught the�  ology in the school of Notre-Dame, Paris. He was consecrated bishop of  Paris in 1159. His Four Books of Sentences (1148-51), a systematic col�  lection of teachings of the Church Fathers and opinions of medieval theo�  logians, served as the standard theological text of the Middle Ages. In it  Peter touched on every doctrinal issue, from God and the Trinity to the four  �last things� (death, judgment, hell, and heaven). He asserted that sacra�  ments are the cause and not merely the signal of grace and that human  actions may be judged good or bad according to their cause and intention.</p><p>Peter the Apostle, Saint orig. Simon (d. c. ad 64, Rome) Disciple  of Jesus, recognized as the leader of the Twelve Apostles. Jesus called him  Cephas (Aramaic for �Rock�; rendered in Greek as �Petros�) and said  �Upon this rock I will build my church� (Matthew 16:18). When Jesus  was arrested, according to the biblical account, Peter denied him three  times, as Jesus had foretold. Accounts of Peter�s life and ministry rely on  the four Gospels, the Acts of the Apostles, the epistles of Peter, and the  epistles of St. Paul. Peter worked with Paul in Antioch and later carried  on missionary work in Asia Minor. According to tradition, he eventually  went to Rome, where he suffered martyrdom by being crucified upside  down. Saint Peter's Basilica is said to have been built on the site of his  grave in Rome. In Roman Catholicism he is regarded as the first in the  unbroken succession of popes. Jesus� promise to give him the �keys of the  kingdom� led to the popular perception of Peter as the gatekeeper of  heaven. The Roman Catholic church celebrates five feast days in honour  of Peter, and in each the name of Paul is associated.</p><p>Peter the Cruel See Peter IV</p><p>Peter the Great See Peter I (Russia), Peter III (Aragon)</p><p>Peter the Great Bay Inlet, Sea of Japan (East Sea), northwestern  Pacific Ocean, in extreme southeastern Russia.

July 8, 1115, Huy,  Flanders) French ascetic and one of the most important preachers of the  First Crusade. A charismatic ascetic, he preached widely in Europe in sup�  port of the First Crusade and led his enthusiastic followers to Constan�  tinople in 1096. They advanced to Nicomedia, but Peter was unable to  maintain discipline; he returned to Constantinople to ask for help from  Alexius I, and in his absence his army was annihilated by the Turks. Peter  reached Jerusalem in 1099 and afterwards returned to France, where he  became prior of an Augustinian monastery.</p><p>Peter the Venerable (b. c. 1092, Montboissier, Auvergne, Arles�d.  Dec. 25, 1156, Cluny, Burgundy) French abbot of Cluny (from 1122). He  joined Bernard de Clairvaux in supporting Pope Innocent II and weakened  the position of the antipope Anacletus II. He befriended Peter Abelard and  reconciled him to Bernard and the pope. Peter�s reforms restored Cluny  to its prominence among the religious establishments of Europe. He also  wrote numerous letters and treatises against heresy, the Jews, and the  Muslims and commissioned the first Latin translation of the Qur�an.</p><p>Peterhof See Petrodvorets</p><p>Peterloo Massacre (Aug. 16,1819) Brutal dispersal of a meeting held  on St. Peter�s Fields in Manchester, Eng. Called to protest unemployment  and high food prices and demand parliamentary reform, the meeting drew  about 60,000 people, including many women and children. Alarmed by  its size, city officials ordered the city�s volunteer cavalry to arrest the  speakers. The untrained cavalry also attacked the peaceable crowd with  sabres, and professional soldiers were sent to join the attack. After a  10-minute rout, about 500 people lay injured and 11 were dead. The inci�  dent (likened to Waterloo) came to symbolize Tory tyranny.</p><p>Peters, Carl (b. Sept. 27, 1856, Neuhaus an der Elbe, Hanover�d.  Sept. 10, 1918, Bad Harzburg, Ger.) German explorer and colonizer in  East Africa. After studying British principles of colonization, he founded  the Society for German Colonization (1884) and made treaties with chiefs  in East Africa to cede their territories to him. He helped establish the Ger�  man East African protectorate of Tanganyika and formed the German East  Africa Company in 1885. He served as imperial high commissioner for  Kilimanjaro (1891�97) and explored the Zambezi River (1899-1901),  where he discovered relics of ancient cities and gold mines.</p><p>Peter's Pence In medieval England, an annual tax of a penny paid by  landowners to the papal treasury in Rome.

The rail centre of  Petersburg, Va., was a strategic defense point near the Confederate capi�  tal of Richmond. In June 1864 the Union army began a siege of both cit�  ies, and each side built fortifications 35 mi (56 km) long. Confederate  troops under Robert E. Lee held the cities, but supplies were scarce and  Lee�s 50,000 troops were immobilized by lack of horses. In April 1865  the 120,000 Union troops under Ulysses S. Grant drove the Confederates  behind Petersburg�s inner defenses, forcing the evacuation of both cities.  Soon thereafter the Confederates surrendered at Appomattox Court House.</p><p>Peterson, Oscar (Emmanuel) (b. Aug. 15, 1925, Montreal, Que.,  Can.) Canadian jazz pianist and composer. Peterson grew up in Montreal  and studied classical piano. His jazz playing, influenced by Art Tatum and  Nat King Cole, is characterized by cascades of notes and an effervescent  swing. After his Carnegie Hall debut in 1949 he became one of the busi�  est pianists in jazz, in demand as an accompanist, solo pianist, and leader  of his own trio. An outstanding, extroverted improviser and sensitive  accompanist, Peterson demonstrates in his performance his roots in swing  as well as bebop.</p><p>Peterson, Roger Tory (b. Aug. 28, 1908, Jamestown, N.Y., U.S.�d.  July 28, 1996, Old Lyme, Conn.) U.S. ornithologist. He started drawing  birds in high school. His Field Guide to the Birds (1934), illustrated with  paintings that stressed the features that best identified a species in the field,  greatly stimulated public interest in bird study in the U.S. and Europe.  Many other guides followed. More responsible than any other person for  fostering a widespread awareness of birds by the American public, he  received such awards as the American Ornithologists� Union�s Brewster  Medal (1944) and the World Wildlife Fund�s Gold Medal (1972).</p><p>Petipa \pa-te-�pa\, Marius (b.

He received his early training from his ballet-master  father and was a principal dancer in France, Belgium, and Spain before  joining the Imperial Theatre in St. Petersburg in 1847. There he also cre�  ated several ballets, including The Pharaoh�s Daughter, which led to his  appointment as chief choreographer in 1869. By his retirement in 1903,  he had produced more than 60 ballets for the imperial theatres in St.  Petersburg and Moscow�including Don Quixote (1869), La Camargo  (1872), Sleeping Beauty (1890), Swan Lake (1895), and The Seasons  (1900)�which formed the core of the classical Russian repertoire.</p><p>Petit \po-'te\, Roland (b. Jan. 13, 1924, Villemomble, Fr.) French  dancer and choreographer. He danced with the Paris Opera Ballet (1940-  44) and then formed several companies, with which he toured Europe and  the U.S. His dramatic ballets combined fantasy with elements of  contemporary realism and included The Strolling Players (1945), The  Young Man and Death (1946), and Carmen (1949). He choreographed  dances for films in the 1950s, and he later staged revues featuring his wife,  Zizi Jeanmaire. From 1973 to 1997 he was director of the Ballet de  Marseille.</p><p>petit Vpe-te\ jury or trial jury Group chosen from the citizens of a  district to try a question of fact at issue in a trial. Though petit juries in  England and the U.S. historically have contained 12 members, there is no  uniform number. Numerical requirements for a valid verdict vary (e.g.,  unanimity in most courts in the U.S., a majority in Scotland and Italy,  two-thirds in Portugal). The petit jury is the standard jury for civil and  criminal trials. It has less discretion than is often imagined. The trial judge  supervises it, rules on what evidence it may view and which laws are  applicable, and sometimes directs or, at the end of the trial, sets aside its  verdict. See also grand jury.</p><p>petition Written instrument directed to an individual, government offi�  cial, legislative body, or court in order to seek redress of grievances or to  request a favour. In some jurisdictions, petitions brought by a sufficient  number of people (represented by their signatures) are used to place a  candidate on a ballot, to submit an issue to the electorate (see referendum  and initiative), or to exert pressure on legislators to vote in a certain way.

Jan. 1, 1823, Kiskoros, Hung.�d. prob�  ably 1856, Siberia) Hungarian poet and revolutionary. He became famous  with his first poetry volume, Versek (1844). Before the revolution of 1848  he wrote poems that glowed with political passion; one of them, �Talpra  magyar� (�Rise, Hungarian�), became an anthem. He disappeared in battle  and was assumed dead in 1849, but archives opened in the 1980s revealed  that he was marched to Siberia and died there. His works are character�  ized by realism, humour, descriptive power, and a peculiar vigour and  have a direct style adapted from national folk songs. Janos vitez (1845),  an entrancing fairy tale, is his most popular epic.</p><p>Petra Vpe-tr q\ Arabic Batra Ancient city, Middle East.

After several centuries as a flourishing trade centre,  it declined with the shifting of trade routes away from the city. It was  captured by the Muslims in the 7th century. Its ruins were rediscovered  in 1812 by the Swiss traveler Johann L. Burckhardt. Excavations since  the mid-20th century have revealed many rock-cut monuments, including  tombs with elaborate facades carved in the rose, crimson, and purple  sandstone of the surrounding hills.

July  20, 1304, Arezzo, Tuscany�d. July 18/19, 1374, Arqua, near Padua, Car�  rara) Italian scholar, poet, and humanist. After 1326 he abandoned the study  of law for his true interests, literature and the religious life. He took minor  ecclesiastical orders and moved to Avignon, where in 1327 he first saw  Laura, the idealized subject of his chaste love and of his celebrated Italian  love lyrics; mainly sonnets and odes written over some 20 years, most were  included in his Canzoniere or Rime (1360). The greatest scholar of his age,  especially of Classical Latin, he traveled widely, visiting learned men,  searching out manuscripts, and undertaking diplomatic missions. He  strongly advocated the continuity between Classical culture and the Chris�  tian message; in combining the two ideals he is considered the founder and  a great representative of humanism. His Latin works, reflecting his religious  and philosophical interests, include On Illustrious Men (begun c. 1337), the  epic poem Africa (begun c. 1338), the autobiographical treatise Petrarch�s  Secret (written 1342-58), De vita solitaria (1345-47; �The Life of Soli�  tude�), and Epistolae metricae (begun c. 1345; �Metrical Letters�). After  1367 he lived in and near Padua. His influence on European literature was  enormous and lasting, and his deep consciousness of the Classical past as  a source of literary and philosophical meaning for the present was of great  importance in paving the way for the Renaissance.</p><p>petrel Any of numerous seabirds (order Procellariiformes, particularly  family Procellariidae), including 24 species (genera Pterodroma and Bul-  weria ) called gadfly petrels because of their fluttering flight. Most are dark  above and light below, with long wings and a short, wedge-shaped tail.  They nest in colonies on tropical and subtropical islands. Both parents  tend the single chick until it is almost fully fledged. During the nonbreed�  ing season, petrels roam the open ocean, eating squid and small fishes.  Species in the family Pelecanoididae are called diving petrels. See also  FULMAR, SHEARWATER, STORM PETREL.</p><p>Petrie Vpe-treV Sir (William Matthew) Flinders (b.

During excavations in Egypt in the mid 1880s  Petrie developed a sequence dating method, based on a comparison of  potsherds at various levels, that made possible the reconstruction of  ancient history from material remains. His excavations, together with  those of Heinrich Schliemann at Troy, marked the beginning of the exami�  nation of successive levels of a site, rather than the previously haphazard  digging. Petrie made many important discoveries in Egypt and Palestine.  His Methods and Aims in Archaeology (1904) was the definitive work of  its time.

It was founded in 1953 as a government-owned monopoly to prospect,  extract, and refine domestic petroleum and to transport that oil and its  derivatives. A government agency sets its policies and oversees its devel�  opment. Although mainly devoted to developing petroleum sources in  Brazil, Petrobras also has interests in the Middle East, North Africa, and  Colombia. In 1995, as part of a campaign to privatize state-owned indus�  tries, the Brazilian government ended the company�s monopoly and  allowed foreign competition. Petrobras subsequently developed joint ven�  tures with foreign businesses.</p><p>petrochemical Strictly, any of a large class of chemicals (as distinct  from fuels) derived from petroleum and natural gas. The category has been  broadened to include a much larger range of organic compounds and a  few inorganic compounds (including carbon black, sulfur, and ammonia).  Some materials cannot be classifed unequivocally because they have alter�  native sources (benzene from coal, ethanol from fermentation). Like crude  oil and natural gas, most petrochemicals consist mainly of carbon and  hydrogen and are called hydrocarbons. Petrochemicals used as raw mate�  rials (feedstocks) include ethylene, propylene, butadiene, benzene, toluene,  xylene, and naphthalene. Among the myriad petrochemical products are  plastics (e.g., polyethylene, polypropylene, polystyrene), soaps and deter�  gents, solvents, drugs, fertilizers, pesticides, explosives, synthetic fibres and  rubberss, paints, epoxies, flooring and insulating materials, luggage, and  recording disks and tapes.</p><p>Petrodvorets \,pyi-tr3-dva-'ryets\ formerly (until 1944) Peterhof  City (pop., 1995 est.: 82,000), northwestern Russia. Located near St.  Petersburg, it was founded by Peter I the Great as a country estate in 1709.  After visiting France in 1717, he decided to create a residence that would  rival the Palace of Versailles. The Baroque Grand Palace (1714-28) was  designed by Domenico Trezzini, and its gardens by Alexandre Le Blond  (1679-1719). It became the most lavish and popular of the Russian royal  summer residences. Today the Grand Palace (now a museum) and the vast  park, with 39 mi (63 km) of canals that connect the intricate system of  fountains, are part of the 2,500-acre (1,000-hectare) preserved area in the  city of Petrodvorets.</p><p>Petrograd See Saint Petersburg</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>petrol &#x25BA; peyote I 1483</p><p>petrol See gasoline</p><p>Petroleos de Venezuela ^pe-tro-'la-os-tha-.ve-nsz-'wa-lsV, SA  (PDVSA) State-owned Venezuelan energy company with interests in oil,  natural gas, coal, and petrochemicals. It was created in 1976 through the  nationalization of Venezuela�s petroleum industry, which had been con�  trolled by foreign companies since the end of World War I. Petroleos de  Venezuela engages in the exploration, refining, and marketing of oil, pet�  rochemicals, and natural gas in many parts of the world. Through its  acquisition of CITGO Petroleum in 1990, PDVSA became a leading sup�  plier of gasoline and other petroleum products in the U.S. Given the scale  of its operations, PDVSA usually earns the largest share of Venezuela�s  foreign currency.</p><p>petroleum or crude oil Complex mixture of hydrocarbons derived  from the geologic transformation and decomposition of plants and ani�  mals that lived hundreds of millions of years ago. As a technical term,  petroleum encompasses the liquid (crude oil), gaseous (natural gas), and  viscous or solid (bitumen, asphalt) forms of hydrocarbons that occur in the  Earth, but the meaning is often restricted to the liquid oil form. Crude oil  and natural gas are the most important primary fossil fuels. Asphalt has  been used since ancient times to caulk ships and pave roads. In the mid  1800s petroleum began to replace whale oil in lamps, and the first well  specifically to extract it was drilled in 1859. The development of the auto�  mobile gave petroleum a new role as the source of gasoline. Petroleum  and its products have since been used as fuels for heating, for land, air,  and sea transport, and for electric power generation and as petrochemical  sources and lubricants. Crude oil and natural gas, produced mostly in  Saudi Arabia, the U.S., and Russia, now account for about 60% of world  energy consumption; the U.S. is by far the largest consumer. At present  rates of consumption, the known supply will be exhausted by the mid 21st  century. Petroleum is recovered from drilled wells, transported by pipe�  line or tanker ship to refineries, and there converted to fuels and petro�  chemicals.</p><p>petroleum trap Subsurface reservoir of petroleum. The oil is always  accompanied by water and often by natural gas; all are confined in porous  rock. The natural gas, being lightest, occupies the top of the trap and is  underlain by the oil and then the water. A layer of impervious rock, called  the roof rock, prevents the escape of the petroleum. The part of the trap  that is actually occupied by the oil and gas is called the petroleum res�  ervoir.</p><p>petrology Scientific study of rocks, including their composition, tex�  ture, and structure; occurrence and distribution; and conditions of origin.  Petrology is concerned with all three major types of rocks: igneous, meta-  morphic, and sedimentary. The subdiscipline of experimental petrology  involves synthesizing rocks in the laboratory to ascertain the physical and  chemical conditions under which they form. The subdiscipline of petrog�  raphy is concerned primarily with the systematic study and description of  rocks using a petrographic microscope.</p><p>Petronas \pe-'tro-nos\ Towers Twin stainless-steel-clad skyscrapers,  linked by a skybridge, in Kuala Lumpur, Malaysia.

He  gave up a life at sea to study medicine, and taught anatomy at the Uni�  versity of Oxford. He founded mines, ironworks, and fisheries in Ireland.  He was also responsible for several inventions and was a founder of the  Royal Society. Petty was an originator of political arithmetic, which he  defined as the art of reasoning by figures upon things relating to govern�  ment. In his best-known work, Treatise of Taxes and Contributions (1662),  he favoured giving free rein to the forces of individual self-interest but  declared the maintenance of a high level of employment to be a duty of  the state. He also argued that the labour necessary for production was the  main determinant of exchange value.</p><p>petunia Any of many species of flowering plants in the genus Petunia ,  in the nightshade family, which originated in South America. The innumer�  able varieties of showy, trumpet-shaped flowers are immensely popular.  There are two types: the compact, erect sort seen in summer garden beds,  and the sprawling, long-stemmed sort seen in hanging baskets and win�  dow boxes. From early summer until frost, petunias bloom profusely with  single or double blossoms; crisped, fringed, or ruffled flowers; and spec�  tacular hues from pure white to deep crimson or purple, speckled or veined  in contrasting colours. Leaves are soft, flabby, and covered with fine,  sticky hairs. Technically perennials, petunias are most often grown as  annuals.</p><p>Pevsner \'pevz-nor\, Antoine orig.

He conceived and edited  the Pelican History of Art series (1953- ); many of these individual vol�  umes have become classics.</p><p>pewter Tin-based alloy used to make domestic utensils. Pewter dates  back at least 2,000 years, to Roman times. Ancient pewter contained about  70% tin and 30% lead. Such pewter, also called black metal, darkened  greatly with age, and the lead readily leached out in contact with acidic  foods. Pewter with little or no lead is of finer quality, and alloys that  include antimony and bismuth are more durable and shinier. Modem pew�  ter is about 91% tin, 7.5% antimony, and 1.5% copper; the absence of  lead makes it safe to use for foods and beverages. The surface of modem  pewter is bluish white with either a bright finish or a soft, satin sheen. It  resists tarnish, retaining its colour and finish indefinitely.</p><p>peyote \pa-'o-te\ Either of two species of the genus Lophophora in the  cactus family, native to North  America, almost exclusively to  Mexico. The body of the peyote cac�  tus is spineless, soft, usually blue-  green, and only 3 in. (8 cm) wide and  2 in. (5 cm) tall. The more common  species, mescal (L. williamsii), has  pink to white flowers. L. diffusa,  more primitive, has white to yellow  flowers and a yellow-green body.</p><p>Well known for its hallucinogenic  effects (primarily due to the alkaloid  mescaline), peyote figures promi�  nently in old and recent religious</p><p>Peyote (Lophophora williamsii )</p><p>DENNIS E.

It is defined as the negative common logarithm  of the concentration of hydrogen ions [H + ] in MOLEs/litre: pH = -log 10  [H + ]. The letters of its name are derived from the absolute value of the  power ip) of the hydrogen ion concentration ( H ). The product of the con�  centrations in water of H + and OH - (the hydroxide ion) is always about  10 -14 . The strongest acid solution has about 1 mole/litre of H + (and about  10 -14 of OH - ), for a pH of 1. The strongest basic solution has about 10 -14  moles/litre of H + (and about 1 of OH - ), for a pH of 14. A neutral solu�  tion has about 10 -7 moles/litre of both H + and OH - , for a pH of 7. The  pH value, measured by a pH meter, titration, or indicator (e.g., litmus)  strips, helps inform chemists of the nature, composition, or extent of reac�  tion of substances, biologists of the composition and environment of  organisms or their parts or fluids, physicians of the functioning of bodily  systems, and agronomists of the suitability of soils for crops and any  treatments needed. The pH is now defined in electrochemical terms (see  electrochemistry).</p><p>Phaedra Vfe-dro\ In Greek legend, the daughter of King Minos. She  became the second wife of Theseus after he abandoned her sister Ariadne.  She later fell in love with her stepson Hippolytus; rejected, she accused  him of rape. He was killed, and she hanged herself.</p><p>Phaedrus \'fe-dros\ (b. c. 15 bc, Thrace�d. c. ad 50, Italy) Roman  fabulist. A slave by birth, Phaedrus became a freedman in Augustus�s  household. He was the first writer to Latinize whole books of fables, pro�  ducing free versions in iambic metre of Greek prose fables that were then  circulating under the name of Aesop. Phaedrus� s renderings, noted for their  charm, brevity, and didacticism, became very popular in medieval Europe;  they include such favourites as �The Fox and the Sour Grapes� and �The  Wolf and the Lamb.�</p><p>Phaethon Vfa-s-thonN In Greek mythology, the son of Helios, the sun  god, and a nymph. Taunted as illegitimate, Phaethon asked for permission  to drive the chariot of the sun through the heavens for a single day in  order to prove that Helios was his father. He proved unable to control the  horses, and, after making a gash in the heavens that became the Milky  Way, he rode too close to earth and began to scorch it. To prevent further  damage, Zeus hurled a thunderbolt, killing him.</p><p>Phag-mo-gru family Vfag-mo-gru\ Tibetan family that in the 14th  century liberated Tibet from Mongol control. At that time Tibet was gov�  erned by lamas from the Sa-skya monastery who resided at the Mongol  (Yuan) court in China. Under Byang-chub rgyal-mtshan (1302-1364), the  Phag-mo-gru liberated central Tibet. For the next 100 years, a semblance  of central authority was reestablished in the country.</p><p>phage See bacteriophage</p><p>phalanger See possum</p><p>phalanx \'fa-,laqks\ Tactical formation consisting of a block of heavily  armed infantry standing shoulder to shoulder in files several ranks deep.  First used by the Sumerians and fully developed by the ancient Greeks,  it is viewed today as the beginning of European military development.  The Greek city-states adopted a phalanx eight men deep during the 7th  century bc. The spectacle of Greek hoplites marching forward in solid  ranks was frightening to the enemy, but the phalanx was difficult to  maneuver and easily thrown into confusion if its ranks were broken.</p><p>phalarope Vfa-l3- l rop\ Any of three species (genus Phalaropus, fam�  ily Scolopacidae) of slim-necked shorebirds, 6-10 in. (25-25 cm) long,  with lobed toes and a straight, slender bill. In summer, their gray-and-  white plumage has red markings. Females fight for nesting territory and  court the males; males, smaller and duller, do all the nesting duties and  lead the young south in autumn. Two species breed around the Arctic  Circle and winter on tropical oceans, where they are known as sea snipe.  Wilson�s phalarope (P. tricolor) breeds in western North America and  migrates to the Argentine pampas.</p><p>Phan Boi Chau Vpan-'boi-'chauX or Phan Giai San Vpan-'gyl-'sanV  orig. Phan Van San (b. 1867, Nghe An province, Viet.�d. Sept. 29,  1940, Hue) Vietnamese resistance figure. Son of a poor scholar, he</p><p>received a doctorate in 1900, by which time he was already a firm nation�  alist. Opposed to French rule in Vietnam, he organized efforts to place the  nationalist Prince Cuong De (1882-1951) on the throne. In 1905 he  moved his resistance movement to Japan, where he met Sun Yat-sen and  Phan Chau Trinh. His monarchist scheme failed, as did a plan to assassi�  nate the governor-general of French Indochina, and Chau was imprisoned  in 1914-17. Hundreds of Vietnamese protested when he was arrested  again in 1925; subsequently released, he spent his remaining years in quiet  retirement.</p><p>Phan Chau Trinh Vpan-'chii-'trinN (b. 1872, Tay Loc, Quang Nam  province, Viet.�d. March 24, 1926, Saigon) Vietnamese nationalist  leader and reformer. Trinh, who fought in the resistance movement against  the French even as a boy, came to believe that modernization was a pre�  requisite for developing an autonomous state, and he thus made modern�  ization his primary goal. He urged replacing the civil service system with  vocational schools and commercial firms, but his attempts to persuade the  French to undertake major reforms failed, and he was twice imprisoned.  He was mourned as a national hero after his death.

The  Phanerozoic, the eon of visible life, is divided into three major eras: the  Paleozoic, Mesozoic, and Cenozoic. Although life originated in Precambrian  time, it was in the Phanerozoic that many forms arose and evolved. The  Earth gradually assumed its present configuration and physical features  through such processes as plate tectonics, mountain building, and glacia�  tion.</p><p>pharaoh \'fer-o\ Epithet applied to Egyptian kings from c. 1500 to 343  bc. The term later evolved into a generic term for all ancient Egyptian  kings. Pharaohs were regarded as gods, retaining their divine status even  after death. A pharaoh�s will was supreme, and he governed by royal  decree, with the assistance of viziers. The common people nevertheless  judged a pharaoh by his deeds; many were criticized, plotted against, and  even deposed and killed. See also Akhenaton; Amenemhet I; Amenhotep II;  Amenhotep III; Ramses II; Thutmose III; Tutankhamen.</p><p>Pharisee \'far-3-,se\ Member of a Jewish religious party in Palestine  that emerged c. 160 bc in opposition to the Sadducees. The Pharisees held  that the Jewish oral tradition was as valid as the Torah. They struggled to  democratize the Jewish religion, arguing that the worship of God was not  confined to the Temple of Jerusalem and fostering the synagogue as an  institution of worship. Their belief that reason must be applied in the  interpretation of the Torah and its application to contemporary problems  is now basic to Jewish theology.</p><p>pharmaceutical industry Producers of pharmaceuticals, substances  used in the diagnosis, treatment, and prevention of disease and the modi�  fication of organic functions. The earliest records of medicinal plants and  minerals are those of the ancient Chinese, Hindu, and Mediterranean civi�  lizations. Medicines were prepared first by physicians and later by apoth�  ecary shops. The modern pharmaceutical industry began in the 19th  century with the discovery of highly active medicinal compounds that  could be manufactured most efficiently on a large scale. As these drugs  replaced the herbal medicines of earlier times, the occurrence and sever�  ity of such diseases as rheumatic fever, typhoid fever, pneumonia, polio�  myelitis, syphilis, and tuberculosis were greatly reduced. Many drugs are  extracted from plant substances; alkaloids such as quinine, cocaine, and  morphine are among the best-known examples. Others are made from  animal substances, such as the glandular extracts that are used to produce  insulin. Pharmaceutical industry research has greatly aided medical  progress, and many new drugs have been discovered and produced in  industrial laboratories. Increasing health-care costs, government regula�  tion, and research ethics are all issues of concern to the industry.</p><p>pharmacology V.far-mo-'kal-o-jeV Branch of medicine dealing with the  actions of drugs in the body�both therapeutic and toxic effects�and  development and testing of new drugs and new uses of existing ones.  Though the first Western pharmacological treatise (a listing of herbal  plants) was compiled in the 1st century ad, scientific pharmacology was  possible only from the 18th century on, when drugs could be purified and  standardized. Pharmacologists develop drugs from plant and animal  sources and create synthetic versions of these, along with new drugs based  on them or their chemical structure. They also test drugs, first in vitro (in  the laboratory) for biochemical activity and then in vivo (on animals,  human volunteers, and patients) for safety, effectiveness, side effects, and</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>pharmacy &#x25BA; phenylketonuria I 1485</p><p>interactions with other drugs and to find the best dose, timing, and route  (mouth, injection, etc.). Drug products are constantly tested for potency  and purity. See also drug poisoning; pharmacy; pharmaceutical industry.</p><p>pharmacy Science dealing with collection, preparation, and standard�  ization of drugs. Pharmacists, who must earn a qualifying degree, prepare  and dispense prescribed medications. They formerly mixed and measured  drug products from raw materials according to doctors� prescriptions, and  they are still responsible for formulating, storing, and providing correct  dosages of medicines, now usually produced by pharmaceutical compa�  nies as premeasured tablets or capsules. They also advise patients on the  use of both prescription and over-the-counter drugs. Laws regulating the  pharmaceutical industry are based on the national pharmacopoeia, which  outlines the purity and dosages of numerous medicinal products.</p><p>Pharsalus \far-'sa-bs\, Battle of (48 bc) Decisive engagement in the  Roman civil war between Julius Caesar and Pompey. Caesar had recently  been defeated by Pompey when the two met again in Greece. Though  Pompey had twice as many men, Caesar used unorthodox tactics to over�  whelm him. Pompey fled and about half his men surrendered; the rest  were killed or took flight.</p><p>pharyngitis \,far-3n-'jl-bs\ Inflammation and infection (usually bacte�  rial or viral) of the pharynx. Symptoms include pain (sore throat, worse  on swallowing), redness, swollen lymph nodes, and fever. Throat culture  may be the only way to distinguish infection with streptococcus bacteria  (strep throat), which can cause rheumatic fever if not treated in time with  antibiotics, from viral infections, which do not respond to antibiotics and  require only symptom relief.</p><p>pharynx Vfar-iqksV Inside of the throat, from the oral and nasal cavi�  ties (see mouth, nose) to the trachea and esophagus. It has three connected  sections: the nasopharynx, at the back of the nasal cavity; the oropharynx,  in the back of the oral cavity down to the epiglottis (a flap of tissue that  closes off the larynx during swallowing); and the laryngopharynx, from  the epiglottis to the esophagus. The oropharynx contains the palatine ton�  sils. The eustachian tubes connect the middle ears to the pharynx, allow�  ing air pressure on the eardrum to be equalized. Disorders include  pharyngitis, tonsillitis, and cancer.</p><p>phase In thermodynamics, a chemically and physically uniform quantity  of matter that can be separated mechanically from a nonhomogeneous  mixture. It may consist of a single substance or of a mixture of substances.  The three basic phases of matter are solid, liquid, and gas; other phases  that are considered to exist include crystalline (see crystal), colloidal (see  colloid), glass, amorphous, and plasma. The different phases of a pure sub�  stance are related to each other in terms of temperature and pressure. For  example, if the temperature of a solid is raised enough, or the pressure is  reduced enough, it will become a liquid.</p><p>phase In wave motion, the fraction of the time required to complete a  full cycle that a point completes after last passing through the reference  position. Two periodic motions are said to be in phase when correspond�  ing points of each reach maximum or minimum displacements at the same  time. If the crests of two waves pass the same point at the same time, they  are in phase for that position. If the crest of one and the trough of the  other pass the same point at the same time, the phase angles differ by  180� and the waves are said to be of opposite phase. Phase differences  are important in alternating electric current technology (see alternating  CURRENT).</p><p>Phazania See Fezzan</p><p>pheasant Any of about 50 specie  family Phasianidae (order Galli-  formes), chiefly Asian but natural�  ized elsewhere.

The simplest one, carbolic acid (C 6 H 5 OH),  is also called phenol; its most important reaction is with formaldehyde, with  which it forms widely used polymers called phenol-formaldehyde (phe�  nolic) resins. Phenols are similar to alcohols but form stronger hydrogen  bonds (see bonding), so they dissolve more readily in water and boil at  higher temperatures. They may be colourless liquids or white solids; many  have a sharp, spicy odour. Some are found in essential oils. Phenols with  higher molecular weights and phenol derivatives have supplanted phenol  itself as industrial antiseptics (germicidal cleaners). See also Leo Baekeland.</p><p>phenol See carbolic acid</p><p>phenomenalism View that statements about material objects are  reducible to statements about actual and possible sensations, or sense-data.  According to phenomenalists, a material object is not a mysterious some�  thing �behind� the appearances presented in sensation. If it were, the  material world would be unknowable; indeed, the term matter is unintel�  ligible unless it somehow can be defined by reference to sensations. In  speaking about a material object, then, reference must be made to a very  large system of possible sense-data, only some of which (if any) are ever  actualized. Thus the statement �There is a fire in the next room� would  be analyzed as a series of hypothetical statements such as �If one were  to enter the next room with one�s eyes open, one would see a bright light  of a yellowish orange colour.� Some philosophers have objected that it is  difficult to remove all references to material objects from the hypotheti�  cal statements to which material-object talk is supposedly reducible. See  also George Berkeley.</p><p>phenomenology Philosophical discipline originated by Edmund Hus�  serl. Husserl developed the phenomenological method to make possible  �a descriptive account of the essential structures of the directly given.�  Phenomenology emphasizes the immediacy of experience, the attempt to  isolate it and set it off from all assumptions of existence or causal influ�  ence and lay bare its essential structure. Phenomenology restricts the phi�  losopher�s attention to the pure data of consciousness, uncontaminated by  metaphysical theories or scientific assumptions. Husserl�s concept of the  life-world�as the individual�s personal world as directly experienced�  expressed this same idea of immediacy. With the appearance of the Annual  for Philosophical and Phenomenological Research (1913-30), under  Husserl�s editorship, his personal philosophizing flowered into an inter�  national movement. Its most notable adherents were Max Scheler and Mar�  tin Heidegger.</p><p>phenotype Vfe-n9-,tlp\ All the observable characteristics of an organ�  ism, such as shape, size, colour, and behaviour, that result from the inter�  action of its genotype (total genetic makeup) with the environment. The  phenotype may change throughout the life of an individual because of  environmental changes and the changes associated with aging. Different  environments can influence the development of inherited traits (e.g., size  is affected by available food supply) and can alter expression by similar  genotypes (e.g., twins brought up in dissimilar families may mature dif�  ferently). Furthermore, not all inherited possibilities in the genotype are  expressed in the phenotype, because some are the result of inactive, reces�  sive, or inhibited genes. See also variation.</p><p>phenylalanine V.fe-ffl-'a-b-.nen, ,fe-n 3 l-'a-b- l nen\ One of the essen�  tial amino acids, present in many common proteins, especially hemoglobin.

Central nervous system effects include  mental retardation and seizures (see epilepsy), with behavioral signs seen  at four to six months of age. Abnormal metabolism also leads to low mela�  nin levels, with light hair, eye, and skin colour. Tests detect this recessive  genetic disorder (see congenital disorder; recessiveness) in two-thirds of the  1 in 10,000 newborns born with high levels of phenylalanine.

Pregnant  women with PKU must resume the diet to prevent severe damage to the  unborn child.</p><p>pheromone \'fer-3- l mon\ Any chemical compound secreted by an  organism in minute amounts to elicit a particular reaction from other organ�  isms of the same species. Pheromones are widespread among insects and  vertebrates (except birds) and are present in some fungi, slime molds, and  algae. The chemicals may be secreted by special glands or incorporated  into other substances (e.g., urine), shed freely, or deposited in selected loca�  tions. Pheromones are used to bring creatures together (e.g., in termite, bee,  and ant colonies), lead them to food (e.g., in scent trails laid by ants), signal  danger (e.g., when released by wounded fish to alert others), attract a mate  and elicit sexual behaviour (numerous examples, possibly including  humans), and influence sexual development (in many mammals and certain  insects). Alarm pheromones often last a shorter time and travel a shorter  distance than other types. In vertebrates, chemical stimuli often influence  parent-young responses. Sex-attractant pheromones are used in certain  products to lure and trap unwanted or harmful insects.</p><p>Phi Beta Kappa Leading academic honour society in the U.S., which  draws its membership from college and university students. The oldest  Greek-letter society in the U.S., it was founded in 1776 as a secret liter�  ary and philosophical society at the College of William and Mary.

After military training in France, he helped organize the Promoters  Revolution of 1932, which ended absolute monarchy in what was then  Siam; in 1939 he changed the country�s name to Thailand. As premier  during World War II, he allied himself with Japan, but, as the war turned  against Japan, his government collapsed. The army seized power in 1947,  and he was reinstalled as premier in 1948. Opposed to communism, he  further allied Thailand to the West during the Cold War by helping estab�  lish the Southeast Asia Treaty Organization. He was ousted by his military  colleagues in 1957 and fled to Japan.</p><p>Phidias \'fid-e-os\ or Pheidias \'fi-de-9s\ (fl. c. 490^130 bc, Athens,  Greece) Greek sculptor. Placed in  charge of the great building program  initiated by Pericles in Athens, he  supervised and probably designed  the overall sculptural decoration of  the Parthenon. He also created its  most important religious images,  including the colossal statue of the  Athena Parthenos (438-436 bc).</p><p>Many of the Parthenon�s sculptures  (the Elgin Marbles) are now in the  British Museum. Ancient writers  considered his masterpiece to be the  statue of Zeus (c. 430 bc) for the  Temple of Zeus at Olympia.

The  site was occupied by the Delaware Indians before William Penn founded the  city in 1682. It was the capital of Pennsylvania 1683-1799 and the capital  of the U.S. between 1790 and 1800. It played a prominent role in opposing  British policies and was the site of the first and second Continental Con�  gresses, the signing of the Declaration of Independence, and the Constitu�  tional Convention. The population grew in the 18th century, with many  immigrants from Scotland, Ireland, and Germany. It was the largest and  most important city of the U.S. in the 19th century and a centre of the anti�  slavery movement. In 1876 it was the site of the U.S. Centennial Exposi�  tion. It is also the site of the U.S.�s oldest art museum (the Pennsylvania  Academy of the Fine Arts, founded in 1805) and the first U.S. hospital (the</p><p>Pennsylvania Hospital, founded in 1751). It is the largest city in the state  and a centre of commerce, finance, industry, and culture.

Philanthropic groups existed in the ancient civilizations of the  Middle East, Greece, and Rome: an endowment supported Plato�s Acad�  emy (c. 387 bc) for some 900 years; the Islamic waqf (religious endow�  ment) dates to the 7th century ad; and the medieval Christian church  administered trusts for benevolent purposes. Merchants in 17th- and 18th-  century western Europe founded organizations for worthy causes. Start�  ing in the late 19th century, large personal fortunes led to the creation of  private foundations that bequeathed gifts totaling millions and then bil�  lions in support of the arts, education, medical research, public policy,  social services, environmental causes, and other special interests.

In 1949 he was  sent to Washington, D.C., as top liaison officer between British and U.S.  intelligence services. He revealed top-secret information to the Soviets  and in 1951 warned Burgess and Donald Maclean (1913-83) that they  were under suspicion, enabling them to escape. Philby himself came under  suspicion and was dismissed from MI-6 in 1955. He worked as a jour�  nalist in Beirut, then in 1963 he fled to the Soviet Union, where he worked  for the KGB and rose to the rank of colonel.

He initially pro�  moted peace with his neighbours, using the time gained thereby to build  his forces and introducing innovations in arms, tactics, and training and  stabilizing his western frontier. His movements on the eastern frontier  provoked the Greeks into forming a coalition against him. He intervened  in the Sacred War to free Delphi from the Phocians, becoming the ally of  Thebes and the Thessalian League, whose president he became. Demos�  thenes turned Athens against him with his Philippics (346-342), and  Thebes also came to view Philip as a threat. He defeated both at the Battle  of Chaeronea, becoming leader of all Greece. He formed the Greek states  into the League of Corinth to attack Persia but was undone by family  politics. After he took a second wife, his first wife, Olympias, left him,  taking Alexander.

April 27, 1404, Halle, Brabant) Duke of Bur�  gundy (1363-1404). He was granted the duchy of Burgundy by his father,  John II, and by marriage and purchase he acquired additional lands in  northern and central France, Flanders, and the Netherlands. He shared the  government with his brothers during the minority of his nephew Charles  VI, ensuring friendly relations with England and Germany. When Charles  went insane (1392), Philip became virtual ruler of France. He formed an  alliance with England (1396) and withdrew his support of the Avignon  papacy (1398).</p><p>Philip II French Philippe known as Philip Augustus (b. Aug. 21,  1165, Paris�d. July 14, 1223, Mantes) French king (1179-1223). The first  of the great Capetian kings, he gradually reconquered the French territories  held by the kings of England. He joined with Richard I on the Third Crusade,  but the two kings soon quarreled. Philip returned to France (1191) and  attacked English possessions; imprisoned in Austria on his journey home,  Richard was freed in 1194 and promptly went to war with the French. When  Richard was killed (1199), his brother John signed a treaty with Philip  (1200), but within two years France and England were again at war. Philip  conquered Normandy (1204) and subdued Maine, Touraine, Anjou, and  most of Poitou (1204-05). John later organized a coalition against France,  but he was defeated by Philip at the Battle of Bouvines (1214). Philip also  expanded his territory into Flanders and Languedoc.</p><p>Philip II Spanish Felipe \fa-'le-pa\ (b. May 21, 1527, Valladolid,  Spain�d. Sept. 13, 1598, El Esco-  rial) King of Spain (1556-98) and of  Portugal (as Philip I, 1580-98). The  son of Emperor Charles V, Philip  received from his father the duchy of  Milan (1540), the kingdoms of  Naples and Sicily (1554), the Neth�  erlands (1555), and Spain and its  overseas empire (1556). He ruled  from the Netherlands from 1555 and  waged a successful war against  France in 1557. From 1559 he ruled  from Spain, where he built the pal�  ace of El Escorial and encouraged  Spain�s literary golden age. He was  a champion of the Counter-  Reformation but failed to put down  rebellions in the Netherlands (from  1568) and to conquer England, suf�  fering the defeat of the Spanish  Armada (1588). He gained a victory  in the Mediterranean with the defeat  of the Ottoman offensive at the Battle of Lepanto (1571) and unified the  Iberian Peninsula as king of Portugal from 1580. During his reign the  Spanish empire attained its greatest power, extent, and influence.</p><p>Philip III French Philippe known as Philip the Good (b. July 31,  1396, Dijon, Burgundy�-d. June 15, 1467, Bruges) Duke of Burgundy</p><p>(1419-67). The most important of the Valois dukes of Burgundy, he  founded the Burgundian state that rivaled France in the 15th century. He  confirmed his right to Burgundy by signing the Treaty of Troyes with  Henry V of England (1420), and he maintained an alliance with England,  breaking it only during his unsuccessful attempt to capture Calais (1435�  39). Philip avoided conflict with France and instead attacked his smaller  neighbors, conquering Hainaut, Brabant, Holland and Zeeland, and Lux�  embourg by 1443. A renowned patron of the arts, he presided over one  of Europe�s most extravagant courts.</p><p>Philip III Spanish Felipe (b. April 14, 1578, Madrid, Spain�d. March  31, 1621, Madrid) King of Spain and of Portugal (1598-1621). The son  of Philip II, he was an indifferent ruler and allowed royal favourites to gov�  ern in his place. From 1609 his government continued the policy of expel�  ling the Moriscos (Christians of Moorish ancestry), which caused serious  economic problems. The huge sums he spent on court entertainments  exacerbated Spain�s growing economic problems.</p><p>Philip IV French Philippe known as Philip the Fair (b. 1268, Fon�  tainebleau, France�d. Nov. 29, 1314, Fontainebleau) King of France  (1285-1314). On inheriting the French throne, he modeled himself on his  grandfather, Louis IX. He was also king of Navarre (as Philip I, 1284-  1305), ruling jointly with his wife, Joan I of Navarre. War with England  (1294-1303) ended with a peace treaty and the betrothal of his daughter  to the future Edward II. Philip forced a harsh treaty on Flanders in 1305.  He conducted a long struggle with Boniface VIII (1297-1303) that led to  the breakdown of the medieval papacy. He was pacified by succeeding  popes, including Clement V, who began the Avignon papacy. Philip  expelled the Jews from France (1306), and his persecution of the Knights  Templar in 1307 led to their suppression by the pope four years later.</p><p>Philip IV Spanish Felipe (b. April 8, 1605, Valladolid, Spain�d. Sept.  17, 1665, Madrid) King of Spain (1621-65) and of Portugal (as Philip II,  1621-40). He succeeded his father, Philip III. and left the administration of  his rule to his chief ministers, the duke de Olivares (1621-43) and the  duke�s nephew Luis Mendez de Haro (1643-61). Spain�s industry and  commerce declined, and wars against Holland, France, and Germany fur�  ther drained Spain�s economy. Portugal regained its independence (1640),  and Holland was lost by the Peace of Westphalia (1648). A poet and patron  of the arts, Philip was the friend and frequent subject of Diego VelAzquez.</p><p>Philip V (b. 238�d. 179 bc, Amphipolis, Macedonia) King of Mace�  donia (221-179). Son of Demetrius II, he succeeded Antigonus Doson.  He supported the Hellenic League against Sparta, Aetolia, and Elis (220-  217), allying himself with Hannibal in 215 and attacking Roman client  states in Illyria. Rome responded in the First Macedonian War. Intrigue  against Egypt and Philip�s unsuccessful sea battle with Rhodes and Per-  gamum led Rome to initiate the Second Macedonian War, in which it pre�  vailed at Cynoscephalae (197). Rome�s harsh terms eased after Philip  made common cause against its Greek foes. Fearing that Rome would  turn on him again, he attempted to expand by attacking the Balkans (184,  183, 181); he died on a fourth attempt in 179.</p><p>Philip V Spanish Felipe orig. Philippe, duke d'Anjou (b. Dec.  19, 1683, Versailles, France�d. July 9, 1746, Madrid, Spain) King of  Spain (1700-46). Grandson of Louis XIV of France and great-grandson of  Philip IV of Spain, Philip was named to succeed the childless Charles II as  king in 1700. Louis�s refusal to exclude Philip from the line of succes�  sion to the French throne led to the War of the Spanish Succession. The  resultant Peace of Utrecht (1713) deprived Philip of the Spanish Nether�  lands and parts of Italy, but it left him Spain and Spanish America. Ini�  tially influenced by his French advisers through his wife, Maria Luise of  Savoy, after her death (1714) he was influenced by his second wife, Eliza�  beth Farnese, and her Italian advisers. Attempts to secure territories in Italy  caused the formation of the Quadruple Alliance (1718) against Spain.  Philip later brought Spain into the War of the Austrian Succession. His  reign marked the beginning of the Bourbon dynasty in Spain (see house  of Bourbon).</p><p>Philip VI or Philip of Valois \val-'wa\ French Philippe de Valois</p><p>(b. 1293�d. Aug. 22, 1350, near Paris) First French king of the Valois  dynasty (1328-50). He continued Capetian efforts to centralize the state  but made concessions to the nobility, clergy, and bourgeoisie. His knights  killed thousands of rebellious Flemings at the Battle of Cassel (1328). His  disputes with Edward III of England led to the outbreak of the Hundred  Years' War (1337).

Son of  Prince Andrew of Greece and Denmark (1882-1944) and Princess Alice  (1885-1969), a great-granddaughter of Queen Victoria, he was reared in  Britain. In World War II he served in combat with the Royal Navy. In  1947 he became a British subject, taking his mother�s surname. Mount-  batten, and renouncing his right to the Greek and Danish thrones. He  married Princess Elizabeth in 1947 and continued on active service in the  navy until her accession to the throne in 1952.

Drawing on the name of Philip Morris, a London tobacconist  who opened shop in the mid 1800s, the company was incorporated in New  York in 1902 as a British-American venture; ownership shifted to Ameri�  can stockholders in 1919, when the company was renamed Philip Morris  &amp; Co. It became a principal maker of cigarettes in the 1930s and �40s,  and the popularity of its Marlboro cigarettes grew with its use of cowboy  imagery to advertise them in the mid 1950s. The company developed other  American cigarette brands such as Parliament, Virginia Slims, and Merit.  Overseas ventures in the manufacture and marketing of cigarettes led to  the formation of Philip Morris International, which by 1972 had estab�  lished sales in many parts of the world, including the former Soviet Union.  Its global brands include Chesterfield and Lark.</p><p>Philip of Hesse (b. Nov. 13,1504, Marburg, Hesse�d. March 31,1567,  Kassel, Ger.) German nobleman, landgrave of Hesse, and champion of the  Reformation. His skillful management made Hesse a sovereign state. Won to  the cause of Martin Luther, Philip became a Reformation leader in Ger�  many. In 1529 he founded the first Protestant university at Marburg (1529),  and in 1531 he united several princes and towns to form the Schmalkaldic  League. However, his folly in contracting a bigamous second marriage dam�  aged his reputation. After the emperor crushed the league, Philip was  imprisoned (1547-52). Long imprisonment undermined his influence and  his health, though he finally saw Lutheranism gain a position of legal equal�  ity with Catholicism in the Peace of Augsburg (1555). In the year of his  death, he divided Hesse among his four sons.</p><p>Philip of Macedonia See Philip II  Philip of Valois See Philip VI (France)</p><p>Philip the Bold See Philip II (Burgundy)</p><p>Philip the Fair See Philip IV (France)</p><p>Philip the Good See Philip ill (Burgundy)</p><p>Philipon \fe-le-'po n \, Charles (b.

La Carica�  ture, which he introduced in 1830, was suppressed in 1835; Le Charivari,  introduced in 1832, became the inspiration for Punch, subtitled The Lon�  don Charivari.

Many Christian ruins, especially  of the 5th-6th century ad, are spread over the site. St. Paul preached the  gospel to Christian converts there.</p><p>Philippine-American War or Philippine Insurrection (1899-  1902) War between the U.S. and Filipino revolutionaries, which may be  seen as a continuation of the Philippine Revolution against Spanish rule. The</p><p>Treaty of Paris (1898), which concluded the Spanish-American War, trans�  ferred Philippine sovereignty from Spain to the U.S.; but it was not rec�  ognized by Filipino leaders, whose troops controlled the entire  archipelago except the capital city of Manila. By 1902 U.S. troops had  defeated the insurgency, though sporadic fighting continued until 1906.  The U.S. retained possession of the islands (except for the Japanese occu�  pation during World War II) until 1946.</p><p>Philippine Revolution (1896-98) Filipino independence struggle  that failed to end Spanish colonial rule in the Philippines. There had been  numerous quasi-religious uprisings during the more than 300 years of  colonial rule, but the late 19th-century writings of Jose Rizal and others  helped stimulate a more broad-based movement for Philippine indepen�  dence. Spain was unwilling to reform its colonial government, and armed  rebellion broke out in 1896. Rizal, who had advocated reform but not  revolution, was shot for sedition; his martyrdom fueled the revolution.  The rebel forces of Emilio Aguinaldo were unable to defeat the Spanish,  but the Filipinos proclaimed their independence in the wake of Spain�s  defeat in the Spanish-American War (1898). The Treaty of Paris ceded the  Philippines to the U.S., however, and Aguinaldo continued the revolu�  tionary struggle, now against the U.S.; he gave up the struggle after being  arrested in 1901.

The country has a predominantly  market economy based largely on agriculture, light industries, and ser�  vices. The Philippines is a republic with two legislative houses; its chief  of state and head of government is the president. First visited by Ferdi�  nand Magellan in 1521, the islands were colonized by the Spanish, who  retained control until the Philippines were ceded to the U.S. in 1898 fol�  lowing the Spanish-American War. The Commonwealth of the Philippines  was established in 1935 to prepare the country for political and economic  independence, which was delayed by World War II and the invasion of  Japanese troops. The islands were liberated by U.S. forces in 1944-45,  and the Republic of the Philippines was proclaimed in 1946, with a gov�  ernment patterned on that of the U.S. In 1965 Ferdinand Marcos was  elected president. He declared martial law in 1972, which lasted until  1981. After 20 years of dictatorial rule, Marcos was driven from power  in 1986. Corazon Aquino became president and instituted a period of  democratic rule that continued with the elections of subsequent presidents.  The government has tried to come to terms with Muslim independence  fighters in the southern islands by establishing the Muslim Mindanao  autonomous region in southwestern Mindanao and nearby islands.</p><p>Philips Electronics NV in full Royal Philips Electronics NV  Dutch Koninklijke Philips Electronics NV Major Dutch manufac�  turer of consumer electronics, household appliances, lightbulbs, and imag�  ing equipment. It was founded by Dutch engineer Gerard Philips in 1891  to make incandescent lamps and incorporated in 1912 under the name NV  Philips Gloeilampenfabrieken (Dutch: Philips Incandescent Light Works).  Its strong research efforts were consolidated in 1914 in a separate orga�  nization that became the Philips Research Laboratories. It began manu�  facturing radios in the 1920s, and after World War II it marketed stereo  equipment, televisions, and other products under such brand names as  Philips, Magnavox, and Norelco. Philips helped create the compact disc,  the cassette tape, and the videocassette recorder, and it is a leading sup�  plier of diagnostic medical equipment. Renamed Philips Electronics NV  in 1991, the firm has manufacturing and marketing subsidiaries through�  out the world.</p><p>Philistine Member of a group of Aegean origin that settled on the south�  ern coast of Palestine. The Philistines first settled the region during the  12th century bc, about the time the Israelites arrived. They lived in five  cities (the Pentapolis) that together made up Philistia, from which the  Greeks derived the name Palestine. They first fought the Israelites in the  11th century bc. In the 10th century bc they were defeated by the Isra�  elite king David. They were later ruled by Assyria, Egypt, Babylonia, Per�  sia, Greece, and Rome. The group appears prominently in the Old  Testament�from which much of the information about them is derived�  though they left no written records of their own. It is from these many  and coloured biblical references that the term assumes its modern sig�  nificance in the English language.</p><p>Phillips, Irna (b. July 1, 1901, Chicago, Ill., U.S.�d. Dec. 22, 1973,  Chicago) U.S. radio producer and director. She worked as a teacher before  turning to writing for radio and creating the first soap opera, Painted</p><p>Dreams (1930). Later known as  �Queen of the Soaps,� she intro�  duced techniques such as the organ  bridge to give a smooth flow  between scenes and the cliff-hanger  ending to each episode. Her daytime  radio serials included Today�s Chil�  dren (1933-38, 1943-50); The Guid�  ing Light (1937-56; television,  1952-); Road of Life (1937-59); and  Women in White (1938-42, 1944-  48), the first hospital soap opera.

A wealthy graduate of  Harvard Law School, he sacrificed  social status and a prospective politi�  cal career in order to join the antisla�</p><p>Wendell Phillips</p><p>LIBRARY OF CONGRESS, WASHINGTON, D.C.</p><p>very movement. His reputation as an inspirational orator was established  with his address at an abolitionist meeting in 1837 to protest the murder  of Elijah Lovejoy. He became an associate of William Lloyd Garrison and  lectured widely at meetings of the American Anti-Slavery Society, serving  as its president from 1865 to 1870. He also advocated prohibition, woman  suffrage, prison reform, regulation of corporations, and labour reform.</p><p>Phillips curve Graphic representation of the inverse relationship  between the rate of unemployment and the rate of change in money wages.  In 1958 A. W. Phillips plotted British unemployment rates and rates of  change in money wages and found that when unemployment rates were  low, employers were more likely to bid wages up to lure good employ�  ees away from their competitors. He claimed that this was a stable rela�  tionship. In the 1960s macroeconomists substituted the rate of price  inflation for the rate of change in money wages and promulgated the curve  as a tool of economic policy, arguing that the simultaneous achievement  of low unemployment and low inflation was problematic. Monetarists,  including Milton Friedman, claimed the relationship was not stable.</p><p>Philo Judaeus \'fi-lo-ju-'de-9s\ or Philo of Alexandria (b. 10-15  bc, Alexandria�d. ad 45-50, Alexandria) Greek-speaking Jewish phi�  losopher. A leader of the Jewish community of Alexandria, he led a del�  egation to the emperor Caligula c. ad 40 to ask that Jews not be forced to  worship him. His writings provide the clearest view of this development  of Judaism in the Diaspora. His philosophy was influenced by Plato, Aris�  totle, the Neo-Pythagoreans, the Cynics, and Stoicism. In his view of God,  Philo was original in insisting on an individual Providence able to sus�  pend the laws of nature, in contrast to the prevailing Greek view of a  universal Providence which is itself subject to the laws of nature. As the  first to attempt to synthesize revealed faith and philosophic reason, he  occupies a unique position in the history of philosophy. He is regarded  as the most important representative of Hellenistic Judaism and a fore�  runner of Christian theology.</p><p>philodendron V.fi-b-'den-drsnX Any of about 200 species of climbing  herbaceous plants that make up the genus Philodendron in the arum fam�  ily, native to the New World tropics. Some are popular indoor foliage  plants in colder areas and landscape plants in warmer climates. The leaves  are often large and smooth-edged to variously lobed and cut. The inflo�  rescence is seldom produced indoors. Many forms are available in culti�  vation, foremost among them the common heart-leaf ( Philodendron  scandens oxycardium). Large varieties include the spade-leaf philoden�  dron {P. domesticum or P. hastatum ), with triangular leaves up to 2 ft (60  cm) long, and the selloum philodendron (P selloum ), with deeply cut  leaves up to 3 ft (1 m) long.</p><p>Philopoemen \ 1 fi-l3-'pe-m9n\ (b. c. 253, Megalopolis, Arcadia�d. 182  bc, Messene, Messenia) General of the Achaean League. Elected federal  cavalry commander (c. 210) and general of the league (208-207, 206-  205, 201-200), he won victories against the Aetolians and the Spartans,  using Macedonian armour and tactics. In his fourth generalship (193-192)  he failed against the Spartans by sea but crushed their army on land. The  Roman Flamininus stopped his capture of Sparta, but when the Spartan  leader was assassinated Philopoemen added that state to the confedera�  tion.

Inspired by the philosophy of Rene Descartes, the skepticism of the  libertines (or freethinkers), and the popularization of science by Bernard  de Fontenelle (1657-1757), they were dedicated to the advancement of  science and secular thought and to the open-mindedness of the Enlight�  enment. They included Voltaire, Montesquieu, Denis Diderot, Jean Le Rond  d� Alembert, and Jean-Jacques Rousseau. The philosophes compiled the  Encyclopedie, one of the great intellectual achievements of the century.</p><p>philosophical anthropology Study of human nature conducted by  the methods of philosophy.

Philosophy may also be defined as  reflection on the varieties of human experience, or as the rational,  methodical, and systematic consideration of the topics that are of great�  est concern to humanity. Philosophical inquiry is a central element in the  intellectual history of many civilizations. Difficulty in achieving a con�  sensus about the definition of the discipline partly reflects the fact that  philosophers have frequently come to it from different fields and have  preferred to reflect on different areas of experience. All the world�s great  religions have produced significant allied philosophical schools. Western  philosophers such as Thomas Aquinas, George Berkeley, and Soren Kierkeg�  aard regarded philosophy as a means of defending religion and dispelling  the antireligious errors of materialism and rationalism. Pythagoras, Rene  Descartes, and Bertrand Russell, among others, were primarily mathema�  ticians whose views of reality and knowledge were influenced by math�  ematics. Figures such as Thomas Hobbes, Jean-Jacques Rousseau, and John  Stuart Mill were mainly concerned with political philosophy, whereas  Socrates and Plato were occupied chiefly by questions in ethics. The Pre-  Socratics, Francis Bacon, and Alfred North Whitehead, among many oth�  ers, started from an interest in the physical composition of the natural  world. Other philosophical fields include aesthetics, epistemology, logic,  metaphysics, philosophy of mind, and philosophical anthropology.

It usually occurs in surface veins in the lower leg and can be  treated with pain relievers and bed rest, with mild exercise after inflam�  mation subsides. Phlebitis can last for years; in such cases, irritation of  the vein�s inner lining leads to blood-clot formation, a condition known  as thrombophlebitis (see thrombosis).

Phloem is composed of several types  of specialized cells, including sieve-tube cells and phloem fibers. Sieve  tubes (columns of sieve-tube cells), which have perforated areas in their  walls, provide the main channels in which food substances travel. Phloem  fibers are long, flexible cells that make up the soft fibers used commer�  cially (e.g., flax and hemp).</p><p>phlox Any of about 65 species of plants (genus Phlox), belonging to the  family Polemoniaceae, admired both  in gardens and in the wilds for their  clustered heads of flowers. All spe�  cies but one are native to North  America. Phlox is herbaceous, usu�  ally with oval or linear leaves; it has  heads of massed tubular flowers with  five flaring lobes. A few species are  woody, but most are herbaceous  annuals or perennials. Sizes range  from the 5-ft-high (1.5-m) summer  phlox ( P paniculata) to the 18-in.-  high (45-cm) woodland perennial  blue phlox ( P divaricata) to the low-  creeping, freely branching, ever�  green moss pink, or creeping phlox  (P. subulata).</p><p>Phnom Penh \p9-'n6m-'pen\ City (pop., 1999 est.: 938,000), capital of  Cambodia, at the junction of the Sab River (a tributary of the Tonle Sap)  with the Mekong River. Founded in 1434 as the capital of the Khmer king�  dom, it was abandoned several times before being reestablished in 1865.  It was a cultural centre, with many institutions of higher learning. When  the Khmer Rouge came to power in Cambodia in 1975, they forced the  city�s population into the countryside to work in the fields. The city was  repopulated beginning in 1979, and its educational institutions began a  difficult period of recovery from the virtual extermination of Cambodia�s  educated class. Although the city is 180 mi (290 km) from the sea, it is  a major port of the Mekong River valley; it is linked to the South China  Sea via a channel of the Mekong delta in Vietnam.</p><p>phobia Extreme and irrational fear of a particular object, class of objects,  or situation. A phobia is classified as a type of anxiety disorder (a neurosis),  since anxiety is its chief symptom. Phobias are generally believed to result  when fear produced by an original threatening situation (such as a near�  drowning in childhood) is transferred to other similar situations (such as  encounters with bodies of water), the original fear often being repressed or  forgotten. Behaviour therapy can be helpful in overcoming phobias, the pho�  bic person being gradually exposed to the anxiety-provoking object or situ�  ation in a way that demonstrates that no threat really exists.</p><p>Phocaea \fo-'se-o\ Ancient city on the Aegean Sea, northernmost of the  Ionian cities on the western coast of Asia Minor (now the Gulf of Izmir,  Turkey). An important maritime state c. 1000-550 bc, it founded a num�  ber of colonies, including Massilia (Marseille) in the western Mediterra�  nean. It declined after the Persian conquest c. 545 bc. The modem town  of Foga is located in an olive- and tobacco-growing region and attracts  tourists to the ancient city�s ruins.</p><p>Phocis \'fo-sis\ Ancient territory, central Greece. It extended north from  the Gulf of Corinth over the range of Mount Parnassus to the Locrian  Mountains, which formed the northern frontier. Its chief towns were  Elateia, Delphi, and Daulis. Mainly a pastoral region, its early history is  obscure. Traditionally, the Phocians controlled the sanctuary and oracle  at Delphi, but they lost control after a war with neighbouring Greek states  c. 590 bc. Phocis was allied with Sparta in the Peloponnesian War (431-  404 bc) and was conquered by Philip II of Macedon in 346 bc.</p><p>phoebe \'fe-be\ Any of three species (family Tyrannidae, suborder Tyr-  anni) of suboscine passerines with a habit of twitching their tail when  perching. The eastern phoebe (, Sayornis phoebe ) of North America is 7.5  in. (18 cm) long, plain brownish gray above, and paler below. Its call is  a brisk �fee-bee� uttered over and over. It makes a mossy nest, strength�  ened with mud, on a ledge, often under a bridge. Say�s phoebe ( S . saya),  a slightly larger bird with buff-hued underparts, occurs in open country  in western North America. The black phoebe (S�, nigricans), occurring  from the southwestern U.S. to Argentina, is dark above with a white belly.</p><p>Phoenicia \fi-'ne-sh9\ Ancient region, Middle East. Corresponding to  modern Lebanon, with adjoining parts of Syria and Israel, its chief cities  were Sidon, Tyre, and Berot (modern Beirut). The Phoenicians were notable  merchants, traders, and colonizers (see Carthage) of the Mediterranean  region in the 1st millennium bc. The area was conquered successively by  the Assyrians, Babylonians, Persians, and Macedonians under Alexander  the Great. In 64 bc it was incorporated into the Roman province of Syria.</p><p>Phoenician \fi-'ne-sh3n\ One of a people of ancient Phoenicia. They  were merchants, traders, and colonizers who probably arrived from the  Persian Gulf c. 3000 bc. By the 2nd millennium bc they had colonies in  the Levant, North Africa, Anatolia, and Cyprus. They traded wood, cloth,  dyes, embroideries, wine, and decorative objects; ivory and wood carv�  ing became their specialties, and the work of Phoenician goldsmiths and  metalsmiths was well known. Their alphabet became the basis of the  Greek alphabet.</p><p>Phoenix \'fe-niks\ City (pop., 2000: 1,321,045), capital of Arizona, U.S.  It is located on the Salt River. The river valley was occupied as early as  ad 1300 by prehistoric Indians, now known as the Hohokam culture, who  disappeared in the early 15th century. A village was founded on the site  in 1867 and incorporated as a city in 1881. It became the territorial capi�  tal in 1889 and state capital in 1912. There was widespread expansion  after World War II, with the population quadrupling between 1950 and  1960. Phoenix occupies a semiarid valley surrounded by mountains and  irrigated fields; its economy is based on farming, manufacturing, mining,  and tourism.</p><p>phoenix In ancient Egypt and in classical antiquity, a fabulous bird  associated with the worship of the sun. The Egyptian phoenix was said  to be as large as an eagle, with brilliant scarlet and gold plumage and a  melodious cry. Only one phoenix existed at a time, and it lived no less  than 500 years. As its end approached, it built a nest of aromatic boughs  and spices, set it on fire, and was consumed in the flames. From the pyre  was born a new phoenix, which sealed its predecessor�s ashes in an egg  of myrrh and flew to Heliopolis to deposit them on the altar of the sun god.  The phoenix thus symbolized immortality. See also fenghuang.</p><p>Phoenix Islands Group of eight small coral atolls, Kiribati.

Annexed  by Britain in 1889, they were joined to the Gilbert and Ellice Islands in  1937. They became part of independent Kiribati in 1979. Kanton is the  only inhabited atoll.</p><p>Phoenix Park murders (May 6, 1882) Assassination in Dublin of  British officials. The newly arrived chief secretary of Ireland, Lord Fre�  derick Cavendish, and his undersecretary, Thomas Burke, were walking  in Dublin�s Phoenix Park when they were stabbed to death by members  of the Invincibles, a radical Irish nationalist secret society. The murders  caused a revulsion against terrorism and enabled Charles Stewart Parnell  to subordinate the Irish National League to the more moderate Home Rule  Party in Parliament.</p><p>phoneme Smallest unit of speech distinguishing one word (or word  element) from another (e.g., the sound p in tap, which differentiates that  word from tab and tag). The term is usually restricted to vowels and con�  sonants, but some linguists include differences of pitch, stress, and  rhythm. A phoneme may have variants, called allophones, that differ pho�  netically without affecting meaning. Phonemes may be recorded with  special symbols, such as those of the International Phonetic Alphabet. In  transcription, linguists conventionally place symbols for phonemes  between slash marks: /p/.</p><p>phonetics Study of speech sounds. It deals with their articulation (artic�  ulatory phonetics), their acoustic properties (acoustic phonetics), and how  they combine to make syllables, words, and sentences (linguistic phonet�  ics). The first phoneticians were Indian scholars (c. 300 bc) who tried to  preserve the pronunciation of Sanskrit holy texts. The Classical Greeks  are credited as the first to base a writing system on a phonetic alphabet.  Modern phonetics began with Alexander Melville Bell (1819-1905),  whose Visible Speech (1867) introduced a system of precise notation for  writing down speech sounds. In the 20th century linguists focused on  developing a classification system that can permit comparison of all  human speech sounds. Another concern of modern phonetics is the men�  tal processes of speech perception.</p><p>phonics Vfa-niks\ Method of reading instruction that breaks language  down into its simplest components. Children learn the sounds of indi�  vidual letters first, then the sounds of letters in combination and in simple  words. Simple reading exercises with a controlled vocabulary reinforce  the process. Phonics-based instruction was challenged by proponents of  �whole-language� instruction, a process in which children are introduced  to whole words at a time, are taught using real literature rather than read�  ing exercises, and are encouraged to keep journals in which �creative�  spelling is permitted. A strong backlash against whole-language teaching  polarized these two approaches to reading instruction. Many schools have  since come to use a combination of the two techniques.</p><p>phonograph or record player Instrument for reproducing sounds.  A phonograph record stores a copy of sound waves as a series of undu�  lations in a wavy groove inscribed on its rotating surface by the record�  ing stylus. When the record is played back, another stylus (needle)  responds to the undulations, and its motions are then reconverted into  sound. Its invention is generally credited to Thomas Alva Edison (1877).  Stereophonic systems, with two separate channels of information in a  single groove, became a commercial reality in 1958. All modern phono�  graph systems had certain components in common: a turntable that rotated  the record; a stylus that tracked a groove in the record; a pickup that con�  verted the mechanical movements of the stylus into electrical impulses;  an amplifier that intensified these electrical impulses; and a loudspeaker  that converted the amplified signals back into sound. Phonographs and  records were the chief means of reproducing recorded sound at home until  the 1980s, when they were largely replaced by recorded cassettes (see  tape recorder) and compact discs.</p><p>phonology \f9-'na-l3-je\ Study of sound patterns within languages.  Diachronic (historical) phonology traces and analyzes changes in speech  sounds and sound systems over time (e.g., the process by which sea and  see, once pronounced with different vowel sounds, have come to be pro�  nounced alike). Synchronic (descriptive) phonology investigates sound  patterns at a single stage in a language�s development, to identify which  ones can occur and in what position (in English, for example, nt and rk  appear within or at the end of words but not at the beginning).</p><p>phonon \'fo-,nan\ In solid-state physics, a quantum of lattice vibrational  energy. In analogy to a photon (a quantum of light), a phonon is viewed</p><p>as a wave packet with particlelike properties (see wave-particle duality).  The way phonons behave determines or affects various properties of sol�  ids. Thermal conductivity, for instance, is explained by phonon interac�  tions. Phonons also provide the basis for understanding superconductivity  in certain metals.</p><p>Phony War (1939�40) Early months of World War II, marked by no  major hostilities. The term was coined by journalists to derisively describe  the six-month period (October 1939-March 1940) during which no land  operations were undertaken by the Allies or the Germans after the Ger�  man conquest of Poland in September 1939.</p><p>phosgene Vfaz- jen\ or carbonyl chloride Vkar-bs-.nilV Colourless,  highly toxic gas used in chemical warfare as well as in industrial processes  including the making of dyestuffs and polyurethane resins. Either alone  or in combination with chlorine, it was used against troops in World War  I. It smells like musty hay. Inhalation causes severe lung injury several  hours after exposure. First prepared in 1811, it is manufactured by the  reaction of carbon monoxide and chlorine in the presence of a catalyst.  Gaseous phosgene is usually stored and transported as a liquid under  pressure in steel cylinders or as a solution in toluene. Mixed with water,  it forms carbon dioxide and hydrochloric acid.</p><p>phosphate Any of numerous chemical compounds related to phospho�  ric acid (H3PO4). Phosphate salts are inorganic compounds containing the  phosphate ion (PO4 - ), the hydrogen phosphate ion (HPO4 - ), or the dihy�  drogen phosphate ion (H2PO4), along with any cation. Phosphate esters  are organic compounds in which the hydrogens of phosphoric acid are  replaced by organic groups (e.g., methyl, ethyl, phenyl), with one of their  carbon atoms bonding to an oxygen atom in the phosphate group. Nucleic  acids and ATP both contain phosphate; bones and teeth contain calcium  phosphate. Phosphate rock (mainly calcium phosphate) is one of the four  most important basic chemical commodities. Phosphates were formerly  used in detergents, which washed into rivers and lakes, causing water  blooms of algae and bacteria (see eutrophication); such use is now gener�  ally outlawed or regulated. Phosphates are still used in fertilizers, baking  powder, and toothpaste.</p><p>phospholipid \,fas-fo-Ti-p3d\ or phosphatide Any member of a  large class of fatlike organic compounds that in their molecular structure  resemble the triglycerides, except for the replacement of a fatty acid with  a PHOSPHATE-containing polar group. The polar end of the molecule is  soluble in water (hydrophilic) and water solutions (including cytoplasm);  the other, fatty-acid end is soluble in fats (hydrophobic). In a watery envi�  ronment phospholipids naturally combine to form a two-layer structure  (upid bilayer) with the fat-soluble ends sandwiched in the middle and the  water-soluble ends sticking out. Such lipid bilayers are the structural basis  of cell membranes. Phospholipids are the principal components of the mye�  lin sheaths of neurons. Examples of phospholipids include lecithin, ceph-  alins, phosphoinositides (in the brain), and cardiolipin (in the heart). See  also DETERGENT.</p><p>phosphorescence Emission of light from a substance exposed to  radiation and persisting as an afterglow after the exciting radiation has  been removed. Unlike fluorescence, in which the absorbed light is emit�  ted about 10 -8 second after excitation, in phosphorescence the extra  energy absorbed is stored in metastable states and reemitted later. Phos�  phorescence may last from about 10~ 3 second to days or even years. The  term phosphorescence is often applied to luminescence of living organisms,  as well.</p><p>phosphorite Vfas-for-.itV or phosphate rock Rock with a high con�  centration of phosphates in nodular or compact masses. The phosphates  may be derived from a variety of sources, including marine invertebrates  that secrete shells of calcium phosphate and the bones and excrement of  vertebrates. Typical phosphorite beds contain about 30% phosphorus pen-  toxide (P 2 0 5 ) and constitute the primary source of raw materials for phos�  phate fertilizers. Significant deposits in the U.S. include the Phosphoria  Formation in Idaho and the Monterey Formation in California. Major  deposits also occur in the Sechura Desert in Peru.</p><p>phosphorus Nonmetallic chemical element, chemical symbol P, atomic  number 15. The ordinary allotrope, called white phosphorus, is a poison�  ous, colourless, semitransparent, soft, waxy solid that glows in the dark  (see phosphorescence) and combusts spontaneously in air, producing dense  white fumes of the oxide P 4 0 10 ; it is used as a rodenticide and a military  smokescreen. Heat or sunlight converts it to the red phosphorus allotrope,</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1492 I Photian Schism &#x25BA; photometry</p><p>a violet-red powder that does not phosphoresce or ignite spontaneously.  Much less reactive and soluble than white phosphorus, it is used in manu�  facturing other phosphorus compounds and in semiconductors, fertilizers,  safety matches, and fireworks. Black phosphorus, made by heating the  white form under pressure, is flaky like graphite. Phosphorus seldom  occurs uncombined in nature. As the phosphate ion, it is abundant and  widely distributed, in apatite, phosphorite, and many other minerals. Phos�  phorus has valence 3 or 5 in compounds, which have many uses in indus�  try. Phosphine (PH 3 ) is a chemical raw material and a doping agent  (deliberately added impurity) for solid-state electronics components.  Organic phosphorus compounds are used as plasticizers, gasoline addi�  tives, insecticides (e.g., parathion), and nerve gases. In living organisms  the role of phosphorus is essential; it is a component of DNA and RNA,  ATP, and bone.</p><p>Photian Schism See Photian Schism</p><p>Photius \'fo-she-3s. Saint (b. c. 820, Constantinople�d. 10th century;  feast day February 6) Patriarch of Constantinople (858-867, 877-886). A  high-ranking civil servant, he was promoted swiftly through the ecclesi�  astical orders to become patriarch after the deposition of Ignatius, an  action that offended Pope Nicholas I. Photius added to the conflict by  refusing to restore dioceses earlier transferred from the Roman to the  Byzantine church. Angry that Nicholas would not recognize him, Photius  excommunicated the pope (867), thus beginning the Photian Schism. Pho�  tius was deposed the same year but restored in 877 after his successor  died. He and Pope John VIII agreed to return Bulgaria to the Roman  church but to allow Greek bishops to remain.</p><p>Photo-Realism Late 20th-century painting style based on photogra�  phy, in which realistic scenes are rendered in meticulous detail. An off�  shoot of Pop art, it became a trend in U.S. painting in the 1970s among  artists fascinated by camera images. Though photographs had been used  by 19th-century painters such as Eugene Delacroix as substitutes for real�  ity, the Photo-Realists relied on the photograph itself, replicating it in  large-scale detail as the reality on which to base an acrylic painting. Its  subjects often included reflecting surfaces (chrome-plated diners, motor�  cycles, glass-fronted buildings, etc.). Its awesome technical precision,  brilliant colour schemes, and visual complexity earned the style wide  popularity. Its most notable practitioners were Chuck Close, Don Eddy,  Richard Estes, and Audrey Flack.</p><p>Photo-Secession Group of U.S. photographers influenced by the Pic-  torialist movement. Founded in 1902 by Alfred Stieglitz, the Photo-  Secession sought recognition of photography as an art to be judged on its  own terms. It was akin to such groups as the Linked Ring in London, and  its name reflected that of the Sezession movement in Austria and Germany.  The group regularly showed its work at the Little Galleries of the Photo-  Secession, also known as �291� (its address on Fifth Avenue in New York  City), a gallery run by Stieglitz. While Stieglitz did not believe in retouch�  ing or manipulating negatives or prints, others of the group, such as  Edward Steichen, were adherents of the impressionistic soft-focus school  and the new techniques. By 1910 many members of the group left due to  different aesthetic visions. The record of the Photo-Secession is contained  in the quarterly Camera Work (1903-17).</p><p>photocell or photoelectric cell or electric eye Solid-state device  with a photosensitive cathode that emits electrons when illuminated and  an anode for collecting the emitted electrons. Illumination excites elec�  trons, which are attracted to the anode, producing current proportional to  the intensity of the illumination. In a photovoltaic cell, light is used to  produce voltage. In a photoconductive cell, light is used to regulate the  flow of current. Photocells are used in control systems, where interrupt�  ing a beam of light opens a circuit, actuating a relay that supplies power  to a mechanism to bring about a desired operation, such as opening a door  or setting off a burglar alarm. Photocells are also used in photometry and  SPECTROSCOPY.</p><p>photochemical reaction Chemical reaction initiated by absorption of  energy in the form of visible (light), ultraviolet, or infrared radiation. Pri�  mary photochemical processes occur as an immediate result, and second�  ary processes may follow. The most important example is photosynthesis.  Vision depends on photochemical reactions that occur in the eye (see  retina; rhodopsin). In photographic film and paper, light activates their sil�  ver salts to a state that is easy to reduce to metallic silver grains during  development. Bleaching of laundry, tanning of human skin, formation of  Earth�s ozone layer, and many industrial reactions are also photochemi�</p><p>cal. Certain air pollutants (see smog) become more reactive and form  noxious compounds in photochemical reactions.</p><p>photocopier Device for producing copies of text or graphic material  by the use of light, heat, chemicals, or electrostatic charge. Most modern  copiers use a method called xerography.</p><p>photoelectric effect Phenomenon in which charged particles are  released from a material when it absorbs radiant energy (see radiation). It is  often thought of as the ejection of electrons from the surface of a metal plate  when visible light falls on it. It can also occur if the radiation is in the wave�  length range of ultraviolet radiation, X rays, or gamma rays. The emitting sur�  face may be a solid, liquid, or gas, and the emitted particles may be  electrons or ions. The effect was discovered in 1887 by Heinrich Hertz and  explained by Albert Einstein in work for which he received the Nobel Prize.</p><p>photoengraving Any of several processes for producing printing  plates by photographic means (see photography). In general, a plate coated  with a photosensitive substance is exposed to an image, usually on film;  the plate is then treated in various ways, depending on the printing pro�  cess to be used. Photoengraving is particularly useful for reproducing  photographs via the halftone process. See also offset printing.</p><p>photography Method of recording permanent images by the action of  light projected by a lens in a camera onto a film or other light-sensitive  material. It was developed in the 19th century through the artistic aspi�  rations of two Frenchmen, Nicephore Niepce and Louis-Jacques-Mande  Daguerre, whose combined discoveries led to the invention of the first  commercially successful process, the daguerreotype (1837). In addition,  two Englishmen, Thomas Wedgwood and William Henry Fox Talbot, pat�  ented the negative-positive calotype process (1839) that became the fore�  runner of modern photographic technique. Photography was initially used  for portraiture and landscapes. In the 1850s and �60s, Mathew B. Brady  and Roger Fenton pioneered war photography and photojournalism. From  its inception, two views of photography predominated: one approach held  that the camera and its resulting images truthfully document the real  world, while the other considered the camera simply to be a tool, much  like a paintbrush, with which to create artistic statements. The latter  notion, known as Pictorialism, held sway from the late 1860s through the  first decade of the 20th century, as photographers manipulated their nega�  tives and prints to create hazy, elaborately staged images that resembled  paintings. By the 1920s and �30s, a new, more realistic style of photog�  raphy gained prominence, as photographers such as Paul Strand, Edward  Weston, and Ansel Adams began to pursue sharply focused, detailed  images. The Great Depression and two world wars inspired many pho�  tographers, including Walker Evans and Dorothea Lange, to pursue docu�  mentary, often socially conscious photography. Inspired by such work,  many photojournalists, including Alfred Eisenstaedt and Margaret Bourke-  White, also emerged during this period. In the second half of the 20th  century, the urban social scene became a subject of much interest to pho�  tographers, as did celebrity portraiture and fashion photography. At the  turn of the 21st century, photographers took advantage of digital capa�  bilities by experimenting with enormous formats and new manipulative  techniques. As technological advances improve photographic equipment,  materials, and techniques, the scope of photography continues to expand  enormously. See also digital camera.</p><p>photolysis \fo-'ta-l3-s9s\ Breakdown of molecules into smaller units via  absorption of light. Flash photolysis, an experimental technique developed  by Manfred Eigen, Ronald George Weyford Norrish, and George Porter,  studies short-lived chemical intermediates formed in many photochemical  reactions. An intense, brief flash of light splits molecules into short-lived  fragments, which are analyzed by spectrophotometry in a second, less  intense flash.</p><p>photometry \fo-'ta-m3-tre\ Precision measurement of the brightness,  colour, and spectrum of stars and other celestial objects to obtain data on  their structure, temperature, and composition. About 130 bc Hipparchus  used a system that divided the stars into six magnitudes, from brightest to  faintest. Beginning in the 17th century, use of the telescope led to the dis�  covery of many fainter stars, and the scale was extended. The use of pho�  tographic and, since the 1940s, photoelectric equipment has vastly  extended the sensitivity and wavelength range of astronomical photom�  etry. The main (UBVRI) classification system uses wave bands in the  ultraviolet, blue, visual, red, and infrared ranges. More elaborate systems  can distinguish giant and dwarf stars, detect metals in stars, and deter�  mine surface gravity.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>photon &#x25BA; Phraya Taksin I 1493</p><p>To Calvin cycle</p><p>or dark reaction</p><p>The light reaction of photosynthesis. The light reaction occurs in two photosystems (units of chlorophyll molecules). Light energy  (indicated by wavy arrows) absorbed by photosystem II causes the formation of high-energy electrons, which are transferred  along a series of acceptor molecules in an electron transport chain to photosystem I. Photosystem II obtains replacement elec�  trons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to  form molecular oxygen (0 2 ), which is released into the atmosphere. The hydrogen ions are released into the lumen. Additional  hydrogen ions are pumped into the lumen by electron acceptor molecules. This creates a high concentration of ions inside the  lumen. The flow of hydrogen ions back across the photosynthetic membrane provides the energy needed to drive the synthesis  of the energy-rich molecule ATP. High-energy electrons released as photosystem I absorbs light energy are used to drive the syn�  thesis of NADPH. Photosystem I obtains replacement electrons from the electron transport chain. ATP provides the energy and  NADPH provides the hydrogen atoms needed to drive the subsequent photosynthetic dark reaction, or Calvin cycle.</p><p>� MERRIAM-WEBSTER INC.</p><p>photon or light quantum Minute energy packet of electromagnetic  radiation. In 1900 Max Planck found that heat radiation is emitted and  absorbed in distinct units, which he called quanta. In 1905 Albert Einstein  explained the photoelectric effect, proposing the existence of discrete  energy packets in light. The term photon came into use for these packets  in 1926. The energies of photons range from high-energy gamma rays  and X rays to low-energy infrared and radio waves, though all travel at  the same speed, the speed of light. Photons have no electric charge or rest  mass and are the carriers of the electromagnetic field.</p><p>photoperiodism Response by an animal or plant to changes in daily,  seasonal, or yearly cycles of light and darkness. Among animals, sleep,  migration, reproduction, and the changing of coats or plumage are regu�  lated to some extent by day length. In the poultry industry, photoperio�  dism is commonly induced by artificial lighing to maximize egg laying  and body weight. Plant growth, seed setting, germination, flowering, and  fruiting are also affected by day length. Other environmental factors that  modify an organism�s responses include temperature and nutrition.</p><p>photoreception Biological responses to stimulation by light, most  often referring to the mechanism of vision. In one-celled organisms such  as the amoeba, the whole cell may be sensitive to light. Earthworms have  photoreceptive cells scattered over their bodies to help orient themselves  by comparison of light intensities in different directions. Most animals  have localized photoreceptors of varying complexity. In humans, photo�  reception relies on the chemical response of a light-sensitive pigment,  rhodopsin, in photoreceptor cells in the retina of the eye. Stimulation of  those cells results in a stimulus being conducted toward the nervous sys�  tem. Humans, like other vertebrates, have two types of photosensitive  cells, rod cells and cone cells. Rod cells are responsible for vision when  there is little light; cone cells mediate daylight vision and colour. Photo�  reception also refers to photosynthesis in plants. See also sense.</p><p>range from about 18,000 �F (10,000  �C) at the bottom to 8,000 �F (4,000  �C) at the top; its density is about  1/1,000 that of air at the surface of  Earth. Sunspots are photospheric  phenomena. The photosphere has a  granular structure. Each grain (cell),  a mass of hot gas several hundred  miles in diameter, rises from inside  the Sun, radiates energy, and sinks  back within minutes to be replaced  by others in a constantly changing  pattern.</p><p>photosynthesis Process by  which green plants and certain other  organisms transform light into  chemical energy. In green plants,  light energy is captured by chloro�  phyll in the chloroplasts of the leaves  and used to convert water, carbon  dioxide, and minerals into oxygen  and energy-rich organic compounds  (simple and complex sugars) that are  the basis of both plant and animal  life. Photosynthesis consists of a  number of photochemical and enzy�  matic reactions. It occurs in two  stages. During the light-dependent  stage (light reaction), chlorophyll  absorbs light energy, which excites  some electrons in the pigment mol�  ecules to higher energy levels; these  leave the chlorophyll and pass along  a series of molecules, generating for�  mation of NADPH (an enzyme) and  high-energy ATP molecules. Oxy�  gen, released as a by-product, passes  into the atmosphere through pores in  the leaves. NADPH and ATP drive  the second stage, the dark reaction  (or Calvin cycle, discovered by  Melvin Calvin), which does not require light. During this stage glucose is  generated using atmospheric carbon dioxide. Photosynthesis is crucial for  maintaining life on Earth; if it ceased, there would soon be little food or  other organic matter on the planet, and most types of organisms would  disappear.</p><p>phototube See photocell</p><p>photovoltaic effect Process in which two dissimilar materials in close  contact act as an electric cell when struck by light or other radiant energy.  In crystals of certain elements, such as silicon and germanium, the electrons  are usually not free to move from atom to atom. Light striking the crys�  tal provides the energy needed to free electrons from their bound condi�  tion. These electrons can cross the junction between two dissimilar  crystals more easily in one direction than another, so one side of the junc�  tion acquires a negative voltage with respect to the other. As long as light  falls on the two materials, the photovoltaic battery can continue to pro�  vide voltage and current.

Franz Joseph Gall stated the principle  that each of the innate mental faculties is based in a specific brain region  (�organ�), whose size reflects the faculty�s prominence in a person and is  reflected by the skull�s surface. He examined the skulls of persons with par�  ticular traits (including �criminal� traits) for a feature he could identify  with it. His followers Johann Kaspar Spurzheim (1776-1832) and George  Combe (1788-1858) divided the scalp into areas they labeled with traits  such as combativeness, cautiousness, and form perception. Though popu�  lar well into the 20th century, phrenology has been wholly discredited.</p><p>Phrygia Vfri-je-oN Ancient district, west-central Anatolia. It was named  for a people whom the Greeks called Phryges and who dominated Ana�  tolia between the Hittite collapse (12th century bc) and ascent of Lydia (7th  century bc). The Phrygians were possibly of Thracian origin (see Thrace)  and had their capital at Gordium. The kingdom of their legendary ruler,  Midas, ended c. 700 bc with the invasion of the Cimmerians, who burned  the capital. The Phrygians excelled in metalwork, wood carving, carpet  making, and embroidery. Their religious cult of the Great Mother of the  Gods was passed on to the Greeks. Excavations conducted since 1945  have uncovered carved stone tombs and shrines there.</p><p>Phumiphon Adunlayadet See Bhumibol Adulyadej</p><p>Phyfe \'fif\, Duncan orig.

The ancestor is in the tree trunk; organisms that have  arisen from it are placed at the ends of tree branches. The distance of one  group from the other groups indicates the degree of relationship; that is,  closely related groups are located on branches close to one another. Though  phylogenetic trees are speculative, they provide a convenient method for  studying phylogenetic relationships and evolution. See also phylogeny.</p><p>phytogeny \fi-'la-j3-ne\ History of the evolution of a species or group,  especially lines of descent and relationships among broad groups. The  fundamental proposition is that plants or animals of different species  descended from common ancestors. Because the evidence for such rela�  tionships is almost always incomplete, most judgments of phylogenicity  are based on indirect evidence and cautious speculation. Modern tax�  onomy, the science of classifying organisms, is based on phylogeny. Early  taxonomic systems had no theoretical basis; organisms were grouped  according to apparent similarity. Biologists who propose a phylogeny  obtain evidence from the fields of paleontology, comparative anatomy,  comparative embryology, biochemistry, and molecular biology. The data  and conclusions of phylogeny indicate that today�s living creatures are  the product of a historical process of evolution and that degrees of resem�  blance within and between groups correspond to degrees of relationship  by descent from common ancestors.

Research on  human evolution involves the discovery, analysis, and description of fos�  silized human remains. Two key goals are the identification of differences  between humans and their human and nonhuman ancestors, and the clari�  fication of the biological emergence of humankind. A variety of quanti�  tative methods are used, including the comparative analysis of genetic  codes. Research on biological variation among contemporary humans  once relied heavily on the concept of race, but today principles of genet�  ics and the analysis of such factors as blood type have largely eliminated  race as a scientific category.</p><p>physical chemistry Branch of chemistry concerned with interactions  and transformations of materials. Unlike other branches, it deals with the  principles of physics underlying all chemical interactions (e.g., gas laws),  seeking to measure, correlate, and explain the quantitative aspects of reac�  tions. Quantum mechanics has clarified much for physical chemistry by  modeling the smallest particles ordinarily dealt with in the field, atoms  and molecules, enabling theoretical chemists to use computers and sophis�  ticated mathematical techniques to understand the chemical behaviour of  matter. Chemical thermodynamics deals with the relationship between  heat and other forms of chemical energy, kinetics with chemical reaction  rates. Subdisciplines of physical chemistry include electrochemistry, pho�  tochemistry (see photochemical reaction), surface chemistry, and catalysis.</p><p>physical education Training in physical fitness and in skills requir�  ing or promoting it. In the U.S. it is required in most primary and sec�  ondary schools. It generally includes calisthenics, gymnastics, various  sports, and some study of health.

Physical medi�  cine may use diathermy, hydrotherapy, massage, exercise, and functional  training. The last can mean learning to work with a guide dog or a pros�  thesis or learning new ways to carry out everyday activities with a limb  missing, sometimes by using assistive devices.

The philosophy of  physics traditionally has been concerned with clarifying the logical struc�  ture, ontological commitments, and intertheoretic relations of fundamen�  tal physical theories, including relativity, quantum mechanics, and statistical  mechanics. The field also addresses various metaphysical and epistemo�  logical aspects of problems encountered in the foundations of theoretical  physics. Examples include the apparent �directed� nature of time, the  meaning of probabilistic descriptions of the initial state of the universe  in statistical mechanics, the measurement problem in quantum mechan�  ics (the problem of stating in precise terms the conditions in which proba�  bilistic as opposed to deterministic laws apply to the motion of an  elementary particle), and the problem of reconciling quantum mechanics  with special, and ultimately general, relativity. See also uncertainty prin�  ciple; UNIFIED FIELD THEORY.</p><p>physiocrat Member of a school of economics, founded in 18th-century  France, that held that government should not interfere with the operation of  natural economic laws. Generally regarded as the first scientific school of  economics, the physiocratic school (the name refers to the �rule of nature�)  was founded by Francois Quesnay, who demonstrated the economic rela�  tion between a workshop and a farm and asserted that the farm alone added  to a nation�s wealth. Land and agriculture were therefore believed to be the  source of all wealth. The physiocrats envisaged a society in which written  law would be in harmony with NATURAL law. They pictured a predominantly  agricultural society, attacking mercantilism for its emphasis on manufactur�  ing and foreign trade and its mass of economic regulations. Quesnay�s dis�  ciples included Victor Riqueti, count de Mirabeau, and Pierre Samuel du  Pont de Nemours (1739-1817). The school was in decline by 1768, and  after the dismissal of a sympathetic comptroller general in 1776 the leading  physiocrats were exiled. Though many of their theories, notably their  theory of wealth, were later demolished, their introduction of scientific  method to economics had a permanent effect on the discipline.</p><p>physiological psychology Study of the physiological basis of  behaviour. Traditional specializations in the field cover perception, moti�  vation, emotion, learning, memory, cognition, or mental disorders. Also con�  sidered are other physical factors that affect the nervous system, including  heredity, metabolism, hormones, disease, drug ingestion, and diet. An  experimental science, physiological psychology relies heavily on labora�  tory research and quantitative data.</p><p>physiology \,fi-ze-'a-l9-je\ Study of the functioning of living organ�  isms or their constituent tissues or cells. Physiology was usually consid�  ered separately from anatomy until the development of high-powered  microscopes made it clear that structure and function were inseparable at  the cellular and molecular level. An understanding of biochemistry is fun�  damental to physiology. Physiological processes are dynamic; cells  change their function in response to changes in the composition of their  local environment, and the organism responds to alterations in both its  internal and external environment. Many physiological reactions are  aimed at preserving a constant physical and chemical internal environ�  ment (homeostasis). See also cytology.</p><p>phytoflagellate \ .fi-to-'fla-j s-lst\ Any of several protozoans that have  flagella in addition to sharing many characteristics with typical algae,  especially the pigment chlorophyll and various other pigments.

Oceanic phytoplankton is the primary food source,  directly or indirectly, of all sea organisms. Composed of groups with  silica-containing skeletons, such as diatoms and dinoflagellates, phy�  toplankton varies seasonally in amount, increasing in spring and fall with  favourable light, temperature, and minerals.</p><p>pi In mathematics, the ratio of the circumference of a circle to its diameter.  An irrational number (see also transcendental number), it has an approximate  value of 3.14, but its exact value must be represented by a symbol, the  Greek letter 7t. Pi is used in calculations involving lengths, areas, and vol�</p><p>umes of circles, spheres, cylinders, and cones. It also arises frequently in  problems dealing with certain periodic phenomena (e.g., motion of pen�  dulums, alternating electric currents). By the end of the 20th century, com�  puters had calculated pi to more than 200 billion decimal places.</p><p>Piaf, Edith \'pyaf\ English \'pe-,af\ orig. Edith Giovanna Gassion</p><p>(b.

Her mother, a cafe singer, abandoned her at birth; Piaf  became blind at age three as a result of meningitis but recovered her sight  four years later. Her father, a circus acrobat, took her along on tours and  encouraged her to sing. She sang for years in the streets of Paris until  discovered by a cabaret owner who gave her her first nightclub job and  suggested she change her name to Piaf, Parisian slang for �sparrow.� She  was soon singing her chansons (ballads) in the large music halls of Paris.  During World War II she entertained French prisoners of war and aided  several in their escapes. She spent the postwar years touring, gaining  worldwide fame with her intense performances of songs such as �Non,  je ne regrette rien� (�No, I regret nothing�). Her throaty, expressive voice,  combined with her fragile appearance and a dramatic tight spotlight on  her face and hands, made her concerts memorable.</p><p>Piaget \pya-'zha\, Jean (b. Aug. 9, 1896, Neuchatel, Switz.�d. Sept.  17, 1980, Geneva) Swiss psychologist. Trained in zoology and philoso�  phy, Piaget later studied psychology in Zurich (from 1918) with Carl  Gustav Jung and Eugen Bleuler, and he was subsequently affiliated with  the University of Geneva from 1929 until his death. He developed a theory  of �genetic epistemology,� a natural timetable for the development of the  child�s ability to think in which he traced four stages�the sensorimotor  (ages 0-2), preoperational or symbolic (2-7), concrete operational (7-12),  and formal operational (through adulthood)�each marked by increased  cognitive sophistication and ability to use symbols. In 1955 Piaget  founded and became director (to 1980) of an international centre for  genetic epistemology in Geneva. His numerous books include The Lan�  guage and Thought of the Child (1923), Judgment and Reasoning in the  Child (1924), The Origin of Intelligence in Children (1948), and The Early  Growth of Logic in the Child (1964). He is regarded as the foremost  developmental psychologist of the 20th century.</p><p>piano or pianoforte Keyboard instrument with wire strings that  sound when struck by hammers operated by a keyboard. It was invented  in Florence by Bartolomeo Cristofori before 1720, with the particular aim  of permitting note-to-note dynamic variation (lacking in the harpsichord).  It differs from the older clavichord in that its hammers (rather than tan�  gents) are thrown at the strings and bounce back, permitting the struck  string to vibrate loudly. A cast-iron frame is needed to withstand the  strings� tremendous tension. Pianos have taken various shapes. The origi�  nal harpsichord (or wing) shape has survived in the modern grand piano;  the less-expensive square (actually rectangular) piano, standard in the  early 19th century, was replaced by the upright piano, in which the strings  are vertical. For at least 150 years the piano was the most important  instrument in Western music.

From 1944 he led his own groups. His interest in classical music led  to study with Nadia Boulanger (1954-55) and the development of his own  compositional style, infusing elements of jazz and modern music into  tango. Not always initially popular with tango fans, his music is now rec�  ognized as having revived the genre and greatly expanded its artistic  potential.</p><p>Picabia \pe-kab-'ya\, Francis (b.

After studying at the Ecole des Beaux-Arts and the Ecole des Arts Dec-  oratifs, he painted for a time in an Impressionist and then a Cubist style.  Picabia went on to combine the Cubist style with Orphic elements in such  paintings as I See Again in Memory My Dear Udnie (1913-14), to which  he gave proto-Dadaist names. About 1916 he began to paint the satiric,  machinelike contrivances that are his chief contribution to Dadaism. In  1915 in New York City, Picabia, Marcel Duchamp, and Man Ray together  founded an American Dadaist movement. In 1917 Picabia returned to  Europe and joined Dadaist movements in Barcelona, Paris, and Zurich.  After Dadaism broke up about 1921, he followed the poet Andre Breton  into the Surrealist movement. He subsequently painted in Surrealist,  abstract, and figurative styles.</p><p>Picardy Vpi-ksr-deX French Picardie \,pe-kar-'de\ Region (pop., 2003  est.: 1,869,386), encompassing the northern French departements of Oise,  Somme, and Aisne and roughly coextensive with the historical region of  Picardy. In the 13th century the historical region included the countships  of Amienois and Vermandois, which were united with the French crown  by Philip II from 1185. Picardy was joined to Burgundy in 1435 and attached  to France in 1477. The province of Picardy from the 16th century to the  end of the ancien regime in 1789 comprised the Somme River basin from  Saint-Quentin to the English Channel, the basins of the Serre and upper  Oise rivers, and Montreuil on the Canche beyond the Authie River. The  region was the scene of heavy fighting in both world wars, especially in  the First Battle of the Somme (1916). The capital of the French adminis�  trative region of Picardy is Amiens. Picardy has an area of 7,490 sq mi  (19,399 sq km).</p><p>picaresque novel Early form of the novel, usually a first-person nar�  rative, relating the episodic adventures of a rogue or lowborn adventurer  (Spanish, picaro ). The hero drifts from place to place and from one social  milieu to another in an effort to survive. The genre originated in Spain  and had its prototype in Mateo Aleman�s Guzman de Alfarache (1599). It  appeared in various European literatures until the mid-18th century, when  the growth of the realistic novel led to its decline. Because of the oppor�  tunities for satire they present, picaresque elements enriched many later  novels, such as Nikolay Gogol�s Dead Souls (1842), Mark Twain�s Huck�  leberry Finn (1884), and Thomas Mann�s Confessions of Felix Krull</p><p>(1954).</p><p>Picasso, Pablo (Ruiz y) (b. Oct. 25, 1881, Malaga, Spain�d. April  8, 1973, Mougins, France) Spanish-born French painter, sculptor, print-  maker, ceramicist, and stage designer. Trained by his father, a professor  of drawing, he exhibited his first works at 13. After moving permanently  to Paris in 1904, he replaced the predominantly blue tones of his so-called  Blue Period (1901-04) with those of pottery and flesh in his Rose Period  (1904-06). His first masterpiece, Les Demoiselles d Avignon (1907), was  controversial for its violent treatment of the female body and the mask�  like faces derived from his study of African art. From 1909 to 1912 Pi�  casso worked closely with Georges Braque �the only time Picasso ever  worked with another painter in this way�and they developed what came  to be known as Cubism. The artists presented a new kind of reality that  broke away from Renaissance tradition, especially from the use of per�  spective and illusion. Neither Braque nor Picasso desired to move into the  realm of total abstraction in their Cubist works, although they implicitly  accepted inconsistencies such as different points of view, different axes,  and different light sources in the same picture. By 1912 they had taken  Cubism further by gluing paper and other materials onto their canvases.  Between 1917 and 1924 Picasso designed stage sets for five ballets for  Sergey Diaghilev�s Ballets Russes. In the 1920s and �30s, the Surrealists  spurred him to explore new subject matter, particularly the image of the  Minotaur. The Spanish Civil War inspired perhaps his greatest work, the  enormous Guernica (1937), whose violent imagery condemned the use�  less destruction of life. After World War II he joined the Communist Party  and devoted his time to sculpture, ceramics, and lithography as well as  painting. In his late years he created variations on the works of earlier  artists, the most famous being a series of 58 pictures based on Las Meni-  nas of Diego Velazquez. For nearly 80 of his 91 years Picasso devoted  himself to an artistic production that contributed significantly to and par�  alleled the whole development of modern art in the 20th century.</p><p>Piccard \pe-'kar\, Auguste (b.

At the Battle of Gettysburg, he led the climactic attack known as Pickett�s  Charge, in which 4,300 men of his division constituted almost half the  attacking force under James Longstreet. The attempt to breach the Union  lines on Cemetery Ridge was repulsed with the loss of about 60% of his  men. Though criticized for his leadership, he retained his command.</p><p>Pickford, Mary orig. Gladys Mary Smith (b. April 9, 1893, Tor�  onto, Ont., Can.�d. May 28, 1979, Santa Monica, Calif., U.S.) Canadian-  born U.S. film actress. She acted with a stock company from age 5, went  on tour at 8, and was performing on Broadway by 18. She starred in D.W.  Griffith�s The Lonely Villa (1909) and by 1913 was acting in movies  exclusively. One of the first movie stars, she became a symbol of inno�  cence and was known as �America�s sweetheart.� Her silent films include  Tess of the Storm Country (1914), Rebecca of Sunnybrook Farm (1917),  Poor Little Rich Girl (1917), and Pollyanna (1920). A shrewd business�  woman, she formed United Artists Corp. (1919) with her second husband,  Douglas Fairbanks, and others. She received an Academy Award for her  first sound film, Coquette (1929). She retired from acting in 1933 and  received a special Academy Award in 1975.</p><p>Pico Bolivar See Bolivar Peak</p><p>Pico della Mirandola Vpe-ko-.dal-la-me-'ran-do-.laV Giovanni,  conte (count) di Concordia (b. Feb. 24, 1463, Mirandola, duchy of  Ferrara�d. Nov. 17, 1494, Florence) Italian scholar, philosopher, and  humanist. He settled in Florence in 1484 as a protege of Lorenzo de' Med�  ici and Marsilio Ficino. In 1486 he posted in Rome a list of 900 theses on  logic, mathematics, physics, and other subjects that he proposed to defend  against any opponent. His Oration on the Dignity of Man (1486), which  accompanied the posting, epitomizes Renaissance humanism. Accused of  heresy by the pope, he was later cleared, and he was later reconverted to  orthodoxy by Girolamo Savonarola. Pico was the first Christian scholar  to use Kabbalistic doctrine (see Kabbala) in support of Christian theology.  His other works include Heptaplus (a seven-point exposition of the Book  of Genesis) and a synoptic treatment of Plato and Aristotle, of which Of  Being and Unity is a portion. He died at age 31.</p><p>picornavirus \pe-,k6r-n9-'vl-r9s\ Any of a group of the smallest known  animal viruses.

The name (from Latin picti, �painted�) referred to  their body painting or tattooing. They were probably descended from pre-  Celtic peoples. They attacked Hadrian's Wall in 297 and warred constantly  with the Romans. They united their two kingdoms by the 7th century and  converted to Christianity, and in 843 Kenneth I, king of the Scots, included  them in the kingdom of Alba, later Scotland.</p><p>pictography \pik-�ta-gr9-fe\ Expression of words and ideas through  drawings (pictographs), considered a forerunner of true writing. Picto-  graphs are drawn in a standardized way, omitting unnecessary details. A  pictograph that stands for a specific idea or meaning is an ideogram; one  that stands for an individual word is a logogram.</p><p>picturesque Artistic concept and style of the late 18th and early 19th  century characterized by a preoccupation with architecture and landscape  in pictorial combination with each other. In Britain, the picturesque was  defined as an aesthetic quality marked by pleasing variety, irregularity,  asymmetry, and interesting textures; medieval ruins in a natural landscape  were thought to be picturesque. John Nash produced some of the most  exemplary works embodying the concept. See also folly.</p><p>Picus Vpl-k9s\ In Roman mythology, a woodpecker sacred to Mars. A  minor agricultural deity associated with the fertilization of the soil, Picus  was widely worshiped in ancient Italy. Later versions of the myth made  him an early king of Italy, whose bride, Circe, changed him into a wood�  pecker. In art he was shown as a woodpecker mounted on a pillar, and  later as a youth with a woodpecker on his head. The woodpecker was also  an important bird in augury.</p><p>pidgin Vpi-jsnV Language with a very limited vocabulary and a simpli�  fied grammar. Pidgins usually arise to permit communication between  groups with no language in common; if a pidgin becomes established as  the native language of a group, it is known as a creole. Pidgins such as  Chinese Pidgin English and Melanesian Pidgin English arose through  contact between English-speaking traders and inhabitants of East Asia and  the Pacific islands. Other pidgins appeared with the slave trade in Africa  and with the importation of West African slaves to Caribbean plantations.  Most of the small vocabulary of a pidgin language (Melanesian Pidgin  has only 2,000 words, Chinese Pidgin English only 700) is usually drawn  from a single language (Melanesian Pidgin, for example, has an English  word stock of more than 90%).</p><p>Piedmont \'ped-,mant\ Italian Piemonte \pya-'mon-ta\ Autonomous  region (pop., 2001 prelim.: 4,166,442), northwestern Italy. With its capi�  tal at Turin, Piedmont borders France and Switzerland; it has an area of  9,807 sq mi (25,399 sq km). In Roman times its passes connected Italy  with the transalpine provinces of Gaul. In the Middle Ages the house of  Savoy was the region�s most important power. It was a centre during the  19th-century Risorgimento that united Italy. Victor Emmanuel II, originally  king of Piedmont and Sardinia, became modern Italy�s first king in 1861.  Surrounded by mountains, Piedmont is centred on the Po River valley,  which contains some of Italy�s best farmland, producing wheat, rice, and  wines. Its hydroelectric plants supply energy for much of northern Italy.</p><p>Piedmont Geographic region, eastern U.S. Lying between the Appala�  chian Mountains and the Atlantic coastal plain, it is about 600 mi (950  km) long and stretches between the Hudson River and central Alabama.  A relatively low, rolling plateau crossed by many rivers, it is a fertile agri�  cultural region.</p><p>Pielinen \'pe-9-,le-n9n\, Lake Lake, southeastern Finland. Located  near the border with Russia, Lake Pielinen is 56 mi (90 km) long and has  an area of 422 sq mi (1,093 sq km). The lake has many islands and is  drained southward into Lake Saimaa by the Pielis River. It is surrounded  by dense forests, especially on its western shore. The shore is capped by  Koli hill, the centre of a winter sports area.</p><p>Pieman River VpI-msnV River, northwestern Tasmania, Australia. It is  formed near Tullah by the confluence of the Macintosh and Murchison riv�  ers. Rising on the western edge of the central highlands, it is about 70 mi  (115 km) long and flows west to the Indian Ocean. There was some gold  and tin mining in the area during the 1870s and 1890s.

In Romanesque and Gothic  architecture, a feature of the nave arcade is the compound pier, which is  cross-shaped in cross section, with shafts placed in the recesses.</p><p>Pierre \'pir\ City (pop., 2000: 13,876), capital of South Dakota, U.S. It  is located on the Missouri River, in the geographic centre of the state. The</p><p>area was originally inhabited by Arikara Indians. The city was founded  in 1880 as the western terminus of the Chicago and North Western Rail�  way, which spurred its growth as a mining and trade centre. It became the  state capital in 1889. It is the hub of a large, diversified agricultural area  with a significant tourist industry based on nearby lakes.</p><p>Pieta \pya-'ta\ Italian "Pity" Depiction of the Virgin Mary supporting  the body of the dead Christ. The  theme grew out of that of the Lam�  entation, the moment between the  Descent from the Cross and the  Entombment. It first appeared in  Germany in the early 14th century. It  enjoyed greater popularity in north�  ern Europe than in Italy through the  15 th century, yet the supreme repre�  sentation is Michelangelo�s sculpture  (1499) in St. Peter's Basilica. The  Pieta was widely represented in both  painting and sculpture. Michelange�  lo�s conception of Mary bearing  Jesus� body on her knees was stan�  dard until the 16th century, when art�  ists began to place Jesus at Mary�s  feet. Though most religious art  declined after the 17th century, the  Pieta retained its popularity through  the 19th century.</p><p>Pietism Vpi-a-.ti-zonA Reform  movement in German Lutheranism  that arose in the 17th century. Phil�  ipp Jakob Spener (1635-1705), a Lutheran pastor, originated the move�  ment when he organized an �assembly of piety,� a regular meeting of  Christians for devotional reading and spiritual exchange. Spener advo�  cated greater involvement of the laity in worship, more extensive study  of scripture, and ministerial training that emphasized piety and learning  rather than disputation. Under Spener�s successor, August Hermann  Francke (1663-1727), the University of Halle became a centre of the  movement. Pietism influenced the Moravian and Methodist churches (see  Methodism).</p><p>Pietro da Cortona orig. Pietro Berrettini (b. Nov. 1, 1596, Cor�  tona, Tuscany�d. May 16, 1669, Rome, Papal States) Italian painter,  architect, and decorator. The son of a stonemason, he was apprenticed to  a painter in Florence. His first major work, a series of frescoes in the small  church of Santa Bibiana in Rome (1624-26), was commissioned by Pope  Urban VIII, and the patronage of the pope�s family, the Barberinis,  advanced Pietro�s career. The rich exuberance of those Baroque frescoes  was a prelude to his best-known work, the large ceiling fresco Allegory  of Divine Providence and Barberini Power (1632-39) in the Barberini  Palace. Here he demonstrated his mastery of illusion, for the centre of the  vault appears open to the sky and the figures seem to hover in space. He  provided a series of frescoes for the Pitti Palace in Florence. Also a mas�  ter architect, his greatest architectural accomplishment is the church of  Santi Martina e Luca in Rome (1634), the first Baroque church built as a  unitary whole.</p><p>piezoelectricity Xpe-.a-zo-o-.lek-'tri-so-teX Appearance of an electric  field in certain nonconducting crystals as a result of the application of  mechanical pressure. Pressure polarizes some crystals, such as quartz, by  slightly separating the centers of positive and negative charge. The result�  ant electric field is detectable as a voltage. The converse effect also occurs:  an applied electric field produces mechanical deformation in the crystal.  Using this effect, a high-frequency alternating electric current (see alter�  nating current) can be converted to an ultrasonic wave of the same fre�  quency, while a mechanical vibration, such as sound, can be converted  into a corresponding electrical signal. Piezoelectricity is utilized in micro�  phones, phonograph pickups, and telephone communications systems.</p><p>pig Any wild or domestic even-toed ungulate (family Suidae) that is a  stout-bodied, short-legged omnivore, with thick, sparsely bristled skin, a  long mobile snout, small tail, and hooves with two functional and two  nonfunctional digits.

He served in  the U.S. House of Representatives  from 1833 to 1837 and in the Senate  from 1837 to 1842. At the dead�  locked Democratic Party convention  of 1852, he was nominated as a com�  promise presidential candidate;  though largely unknown nationally,  he unexpectedly trounced Winfield  Scott in the general election. For the  sake of harmony and business pros�  perity, he was inclined to oppose  antislavery agitation. His promotion  of U.S. territorial expansion resulted  in the diplomatic controversy of the  Ostend Manifesto. He reorganized  the diplomatic and consular service  and created the U.S. Court of  Claims. Pierce encouraged plans for  a transcontinental railroad and approved the Gadsden Purchase. To pro�  mote northwestern migration and conciliate sectional demands, he  approved the Kansas-Nebraska Act but was unable to settle the resultant  problems. Defeated for renomination by James Buchanan in 1856, he  retired from politics.</p><p>Franklin Pierce.</p><p>LIBRARY OF CONGRESS, WASHINGTON, D.C.</p><p>Piero della Francesca \fran-'ches-ko\ (b. c. 1420, Sansepolcro?,  Republic of Florence�d.

His fresco cycle for San  Francesco at Arezzo, The Legend of  the True Cross (1450s), exemplifies  his simplicity and clarity of struc�  ture, controlled use of perspective,  and aura of serenity. His famous dip�  tych portrait of his patrons, Count  Federico da Montefeltro and his wife  (c. 1470), is known for its unideal�  ized depiction of their features and  the use of landscape in the back�  ground. Though he had little influ�  ence on his contemporaries, Piero�s  important scientific and poetic con�  tributions to Renaissance painting are  now well recognized.

His  name derives from that of his master, Cosimo Rosselli, whom he assisted  on frescoes for the Sistine Chapel. His later mythological paintings exhibit  a bizarre Romantic style. Many are filled with fantastic hybrid human-  animal forms engaging in revels ( The Discovery of Honey, c. 1500) or  fights ( Battle of the Centaurs and the Lapiths, c. 1500). His art reflects his  eccentric personality.

Returning to France, he modeled the first version of his  famous Mercury Fastening His Sandals, which in a later version won him  admission to the Royal Academy (1744). The statue became so popular  that in 1748 Louis XV commissioned a life-size marble version to present  to Frederick II of Prussia. He was also noted for his portrait sculptures. His  Nude Voltaire (1776), an anatomically realistic rendering of the aged phi�  losopher, caused a furor when it was first shown.</p><p>pigeon Plump, small-billed, monogamous birds of the family Colum-  bidae, found almost worldwide and recognizable by their head-bobbing  strut.

Common street pigeons, or rock doves, are  descendants of the Eurasian rock dove ( Columba livia). From antiquity  pigeons were trained to carry messages over long distances. About 115  species of fruit pigeons occur in Africa, southern Asia, Australia, and the  Pacific islands.

They may be inorganic com�  pounds (usually brighter and longer-lasting) or organic compounds. Natu�  ral organic pigments have been used for centuries, but today most are  synthetic or inorganic. The primary white pigment is titanium dioxide. Car�  bon black is the most usual black pigment. Iron oxides give browns, rang�  ing from yellowish through orange to dark brown. Chromium compounds  yield chrome yellows, oranges, and greens; cadmium compounds brilliant  yellows, oranges, and reds. The most common blues, Prussian blue and  ultramarine, are also inorganic. Organic pigments, usually synthesized  from aromatic hydrocarbons, include the nitrogen-containing azo pigments  (red, orange, and yellow; see azo dyes) and the copper phthalocyanines (bril�  liant, strong blues and greens).

The chief attractions for pilgrims in the Middle Ages were  the Holy Land, Santiago de Compostela in Spain, and Rome, but there were  hundreds of local pilgrimage sites, including the tomb of St. Francis of  Assisi and that of St. Thomas Becket in Canterbury. More recent pilgrimage  sites include the shrine of Our Lady of Guadalupe in Mexico (1531),  Lourdes in France (1858), and Fatima in Portugal (1917). The tradition of  pilgrimage is also important in Buddhism, with sites including Bodh Gaya,  where the Buddha received enlightenment, and Varanasi, where he deliv�  ered his first sermon.

It may  grow to 2 ft (60 cm) but is usually about 14 in. (35 cm) long. Five to  seven distinctive vertical dark bands mark the bluish body. Pilot fishes  follow sharks and ships, apparently to feed on parasites and leftover  scraps. It was formerly thought that they were leading, or �piloting,� the  larger fishes to food.</p><p>pilot whale Any of one to three species (genus Globicephala, family  Delphinidae) of toothed whale found in all oceans except the Arctic and  Antarctic, also called caa�ing whale for a roaring sound it makes when  stranded. It is black, usually with a lighter splash on the throat and chest,  and has a round, bulging forehead, a short beaklike snout, and slender,  pointed flippers, and grows to 13-20 ft (4-6 m) long. Pilot whales live in  large schools, sometimes hundreds or thousands, feeding mainly on squid.  They have been kept in oceanariums and trained to perform.</p><p>Pitsudski \pil-'sut-ske, pil-'ziit-ske\, Jozef (Klemens) (b. Dec. 5,  1867, Zulow, Pol., Russian Empire�d. May 12, 1935, Warsaw, Pol.) Pol�  ish revolutionary leader. Reared with a hatred for Russian oppression, he  was politically active and was banished to Siberia for his socialist agita�  tion (1887-92), and he became a leader of the Polish Socialist Party on  his return. In 1908 he organized the secret Union of Military Action,  which fought in World War I under Austro-Hungarian command against  the Russians. In 1916 he demanded recognition of Poland�s independence,  which was granted in 1918. He served as Poland�s first head of state until  the constitution was established in 1922. After staging a coup in 1926, he  served as premier (1926-28) and minister of defense (1926-35) under  handpicked premiers, enabling him to rule as the dictator of Poland.</p><p>Piltdown hoax Forgery of human fossil remains that impeded early  20th-century progress in the study of human evolution. The apparently  fossilized skull found at Piltdown Common near Lewes, Eng., was first  proposed as a new species of prehistoric man (�Piltdown man�) in 1912.  Only in 1954 was the skull shown to consist of a human cranium skill�  fully joined to the jaw of an orangutan. The hoax may have been perpe�  trated by the skull�s discoverer, Charles Dawson, though evidence  discovered in the 1970s suggests a British Museum staff member, Martin  A.C. Hinton.</p><p>Pima Vpe-m3\ North American Indian people living mainly in Arizona,  U.S. The Pima language is of Uto-Aztecan language stock, and the name  Pima was given by the Spanish, who may have derived it from the phrase  pi-nyi-match, meaning �I don�t know.� They call themselves Akimel  O�odham, meaning �River People.� Their traditional lands are located in  the core area of the prehistoric Hohokam culture, from which they prob�  ably descend. The Pima originally were sedentary com farmers who lived  in one-room houses and used the Gila and Salt rivers for irrigation. Some  hunting and gathering were also done. Their villages were larger than  those of the related Papago Indians, and they possessed a stronger tribal</p><p>Pill bugs (Armadillidium vulgare)</p><p>E.S.

A common flavouring in Hungarian dishes, paprika is made  by grinding dried peppers. The term pimento sometimes refers to allspice  because early Spanish explorers of the West Indies and Central America  mistook the highly aromatic berries of the tropical allspice tree for a type  of pepper and called it pimenta.</p><p>pin (fastener) In mechanical and civil engineering, a peg or bar  designed to fasten machine and structural components together or to keep  them aligned. Dowel pins are used to keep machine components aligned,  sometimes without making a rigid joint (as in a pin-connected truss).  Taper pins are used to fix the hub of a gear or a pulley to a shaft. Split  cotter pins prevent nuts from turning on bolts and keep loosely fitting pins  in place. The clevis pin has a ridge at one end and is kept in place by a  cotter pin inserted through a hole in the other end. Many other types of  pins are used in various machines.</p><p>Pinatubo X.pe-na-'tii-boV, Mount Volcano, western Luzon, Philippines.  Located about 55 mi (90 km) northwest of Manila, it rose to a height of  about 4,800 ft (1,460 m) before its eruption in 1991 (for the first time in  600 years). Its explosions produced a column of smoke and ash more than  19 mi (30 km) high and left some 100,000 people homeless. The ashfalls  forced the evacuation and eventual closing of a nearby U.S. Air Force  base. The eruption was one of the largest of the 20th century.</p><p>Pinchback, Pinckney (Benton Stewart) (b. May 10, 1837,  Macon, Ga., U.S.�d. Dec. 21, 1921, Washington, D.C.) U.S. politician.  Born to a former slave and a white planter, he became a steward on river  steamboats. At the outbreak of the American Civil War, he reached Union-  held New Orleans, where he raised and led a company of black Union  volunteers called the Corps d�Afrique (1862-63). After the war he was  elected to the Louisiana senate (1868) and served as lieutenant governor  (1871). Elected to the U.S. House of Representatives (1872) and Senate  (1873), he was denied his seat in each body on unproved charges of elec�  tion fraud. He subsequently became a lawyer and moved to Washington,  D.C.</p><p>Pinchot Vpin-shoV, Gifford (b. Aug. 11, 1865, Simsbury, Conn.,  U.S.�d. Oct. 4, 1946, New York, N.Y.) U.S. forestry and conservation  pioneer. He graduated from Yale University and studied forestry in  Europe. In 1892 he became the first professional U.S. forester. In 1896  he joined the national forest commission of the National Academy of Sci�  ences and helped plan the U.S. system of forest reserves (later national  forests). As chief of the U.S. Forest Service (1898-1910), he established  the nation�s forest-service system. He founded the Yale School of For�  estry and taught there from 1903 to 1936. He served as governor of Penn�  sylvania from 1923 to 1927 and from 1931 to 1935.</p><p>Pinckney, Charles (b. Oct. 26, 1757, Charleston, S.C.�d. Oct. 29,  1824, Charleston, S.C., U.S.) U.S. statesman. A cousin of Charles C.  Pinckney and Thomas Pinckney, he fought in the American Revolution. From  1784 to 1787 he served in the Continental Congress, where he was instru�  mental in calling for the Constitutional Convention. As a delegate to the  convention from South Carolina, he proposed numerous provisions that  were incorporated in the final draft of the Constitution of the United States.  He helped write the South Carolina constitution and was also governor  of the state (1789-92, 1796-98, 1806-08). He served in the U.S. Senate  from 1798 to 1801 and as minister to Spain from 1801 to 1805.</p><p>Pinckney, Charles Cotesworth (b. Feb. 25, 1746, Charleston,  S.C.�d. Aug. 16, 1825, Charleston, S.C., U.S.) U.S. soldier, statesman,  and diplomat. A cousin of Charles Pinckney and the brother of Thomas  Pinckney, he was an aide to George Washington in the American Revolu�  tion, commanded at Savannah, Ga., and was promoted to brigadier gen�  eral in 1783. He was a delegate to the Constitutional Convention.  Appointed minister to France (1796), he was involved in negotiations that  ended in the XYZ Affair; when one of the group of French negotiators  suggested that the U.S. representatives offer a gift in order to gain a peace  treaty, Pinckney is said to have replied, �No! No! Not a sixpence!� He  was the unsuccessful Federalist candidate for vice president in 1800 and  for president in 1804 and 1808.</p><p>Pinckney, Eliza orig. Elizabeth Lucas (b. c.

The daughter of a British landowner in South Carolina,  she managed his plantations from 1739. Experimenting with various  crops, she succeeded in marketing the first American crop of indigo. After  her marriage to the lawyer Charles Pinckney (1744), she revived the cul�  tivation of silkworms and manufacture of silk on his plantation. She con�  tinued to manage their extensive landholdings after his death (1758).  Charles C. Pinckney and Thomas Pinckney were her sons.</p><p>Pinckney, Thomas (b. Oct. 23, 1750, Charleston, S.C.�d. Nov. 2,  1828, Charleston, S.C., U.S.) U.S. soldier, politician, and diplomat. The  brother of Charles C. Pinckney and a cousin of Charles Pinckney, he served  as governor of South Carolina (1787-89) and as minister to Britain (1792-  96). As special envoy to Spain (1795), he negotiated the Treaty of San  Lorenzo, also called Pinckney�s Treaty, which fixed the southern border  of the U.S. and granted the U.S. navigation rights on the Mississippi River  and the right of deposit (storage of goods) at New Orleans. He was a major  general in the War of 1812.</p><p>Pindar (b. 518/522, Cynoscephalae�d. c. 438 bc, Argos) Greek poet.  A Boeotian of aristocratic birth, Pindar was educated in neighbouring  Athens and lived much of his life in Thebes. Almost all his early poems  have been lost, but his reputation was probably established by his later  hymns in honour of the gods. He developed into the greatest lyric poet  of ancient Greece, respected throughout the Greek world. Of his 17 vol�  umes, comprising almost every genre of choral lyric, only four have sur�  vived complete, and those lack his musical settings. The extant poems,  probably representing his masterpieces, are odes (see Pindaric ode) com�  missioned to celebrate triumphs in various Hellenic athletic games. Lofty  and religious in tone, they are noted for their complexity, rich metaphors,  and intensely emotive language.</p><p>Pindaric ode Ceremonious poem in the manner of Pindar, who  employed a triadic, or three-part, structure consisting of a strophe (two  or more lines repeated as a unit) followed by a metrically harmonious  antistrophe and an epode (summary line) in a different metre. The three  parts correspond to movements onstage by the chorus in Greek drama.  After the 16th-century publication of Pindar�s choral odes in the epinicion  (celebratory) form, poets writing in various vernaculars created irregular  rhymed odes that suggest his style. Such odes in English are among the  greatest poems in the language, including John Dryden�s �Alexander�s  Feast,� William Wordsworth�s �Ode: Intimations of Immortality,� and  John Keats�s �Ode on a Grecian Urn.�</p><p>pine Any of 10 genera of coniferous trees (rarely shrubs) of the family  Pinaceae (see conifer), native to  northern temperate regions, espe�  cially about 90 species of ornamen�  tal and timber evergreen conifers of  the genus Pinus.

May 24, 1855, London,  Eng.�d. Nov. 23, 1934, London) British playwright. He entered the the�  atrical world as an actor with Henry Irving�s theatre company. His first  play, �200 a Year, was produced in 1877. He wrote a series of successful  farces such as The Magistrate (1885) before turning to dramas of social  issues. The Second Mrs. Tanqueray (1893), the first of his plays depict�  ing women confronting their situation in society, established his reputa�  tion, and he followed it with works such as The Notorious Mrs. Ebbsmith  (1895) and Trelawny of the � Wells � (1898), becoming the most success�  ful playwright of his time.</p><p>Ping Pong See table tennis</p><p>Pinilla, Gustavo Rojas See Gustavo Rojas Pinilla</p><p>pinion See gear, rack and pinion</p><p>Pinios River \,pe-ne-'6s\ or Peneus River \pi-'ne-os\ River, Thessaly,  north-central Greece.

In pre�  historic times it formed a great lake before it broke through the Vale of  Tempe. It is navigable in its lower course.</p><p>pink family Family Caryophyllaceae, composed of 2,070 species of  flowering plants in 89 genera found mainly in northern temperate regions.  The approximately 300 species of true pinks belong to the genus Dianthus\  relatively easy to grow, these are popular in rock gardens for their fragrant,  showy flowers. Though members of the pink family are diverse in appear�  ance and habitat, most have swollen leaf and stem joints. The family  includes carnations, baby's breath, sweet William, campion, and chickweed.</p><p>pink salmon Food fish (Oncorhynchus gorbuscha, family Salmonidae)  of the North Pacific that constitutes half of the commercial fishery of  Pacific salmon.

The agency was founded in 1850 by Allan Pinkerton (1819-84),  former deputy sheriff of Cook county, Ill. It originally specialized in rail�  way theft cases, protecting trains and apprehending train robbers. It solved  the $700,000 Adams Express Co. theft in 1856, and in 1861 it thwarted  an assassination plot against president-elect Abraham Lincoln. It later par�  ticipated in anti-labour union activities (see Homestead Strike). It was  instrumental in breaking up the Molly Maguires.</p><p>Pinkham Vpiqk-omX, Lydia E(stes) (b.

Her compound, a blend of ground herbs, was 18% alco�  hol by content. In 1875 the Pinkham family decided to go into business  selling the medicine, which Pinkham claimed could cure any �female  complaint� from nervous prostration to a prolapsed uterus. It quickly  gained acceptance, and the business was soon grossing close to $300,000  a year. Not until the 1920s, when federal regulation of drugs and adver�  tising increased, did the Lydia E. Pinkham Medicine Co. reduce both the  alcohol content of the medicine and the claims for its efficacy.</p><p>pinniped Vpi-no-.pedX Any member of the three existing families of  aquatic, fin-footed mammals that constitute the suborder Pinnipedia (order  Carnivora; see carnivore).

Nov. 25, 1915, Valparaiso, Chile) Head of Chile�s military government  (1974-90). A career military officer, he planned and led the coup d�etat in  which Pres. Salvador Allende died. He immediately moved to crush liberal  opposition and in the next three years arrested about 130,000 Chileans and  foreigners, many of whom were tortured and some of whom were killed.  He led a rapid transition to a free-market economy, which slowed inflation  but led to acute hardship for the lower classes. A new constitution in 1981  granted him eight more years as president. Rejected in a plebiscite in 1989,</p><p>he stepped down after free elections installed Patricio Aylwin in 1990. In  1998 he was arrested in England at the request of Spain and held for trial for  crimes against Spanish citizens in Chile during his tenure; he was released  16 months later. He was then indicted in Chile for the murder of dissidents  but was declared mentally unfit for trial.</p><p>pinochle Vpe-.no-kolX Card game. In one popular version of pinochle  three players use two packs of 24 cards ranking ace, 10, king, queen, jack,  and 9 of each suit. Each player is dealt 15 cards, 3 at a time. Bidding is  based on certain combinations of cards within the player�s hand and an  estimation of tricks, or hands, the player can win. The name derives from  Binokel, a German game resembling bezique.</p><p>Pinsky, Robert (b. Oct. 20, 1940, Long Branch, N.J., U.S.) American  poet and critic. Pinsky was poetry editor of The New Republic from 1979  to 1986. His own poems, many of which are to be found in The Figured  Wheel: New and Collected Poems (1996), often explore the meaning of  ordinary acts. He also did a notable verse translation of Dante�s Inferno  (1994). Pinsky was poet laureate consultant from 1997 to 2000.</p><p>pintail Any of four species (genus Anas, family Anatidae) of sleek,  long-tailed, long-necked dabbling ducks that are swift fliers and popular  game birds. The common, or northern, pintail (A. acuta), widespread in  the Northern Hemisphere, is a long-distance flier; some Alaskan birds  winter in Hawaii. It is 26-30 in. (66-75 cm) long. The male has a white  breast, gray back, and black tail; the female is mottled brown. The pre�  ferred diet is seeds. The brown, or yellow-billed, and the Bahama, or  white-cheeked, pintails are primarily found in South America. The red�  billed pintail is a grayish African species.</p><p>Pinter, Harold (b. Oct. 10, 1930, London, Eng.) British playwright.  Born into a working-class family, he acted with touring companies until  1959. His early one-act plays were followed by the full-length The Birth�  day Party (1958). His next major plays. The Caretaker (1960) and The  Homecoming (1965), established his reputation as an innovative and com�  plex dramatist, sometimes considered as belonging to the Theatre of the  Absurd. He often used disjointed small talk and lengthy pauses in dialogue  to convey a character�s thought, which often contradicts his speech. Pint�  er�s laterplays include Old Times (1971), No Man's Land (1975), Betrayal  (1978; film, 1983), Mountain Language (1988), and Moonlight (1993). He  also wrote radio and television plays as well as screenplays for The  Go-Between (1970), The French Lieutenant�s Woman (1981), and The  Handmaid�s Tale (1990). In 2005 he won the Nobel Prize for Literature.</p><p>pinto Spotted horse, also called paint, piebald, skewbald, and other terms  to describe variations in colour and markings. The American Indian ponies  of the western U.S. were often pintos. Most pure-breed associations refuse  to register horses with pinto colouring. Pintos have colour patterns called  overo (white spreading irregularly up from the belly, mixed with a darker  colour) and tobiano (white spreading down from the back in smooth,  clean-cut patterns).</p><p>Pinturicchio V.pen-tii-'rek-kyoN or Pintoricchio \,pen-t6-'rek-kyo\  orig. Bernardino di Betto di Biago (b. c. 1454, Perugia,  Romagna�d. Dec. 11, 1513, Siena, Republic of Siena) Italian painter. He  assisted Perugino on the frescoes in the Vatican�s Sistine Chapel (1481-82).  Painting in the early Renaissance style, he was more interested in deco�  rative effects than in clarity of design; his most important work, the fresco  decoration of six rooms in the Bor�  gia Apartments for Pope Alexander  VI (1492-94), features brilliant  colours, gilding, and ancient Roman  ornamental motifs. His last major  works were 10 scenes from the life  of Pius II in the Piccolomini Library  of Siena Cathedral. He was also a  prolific panel painter.</p><p>pinworm Common species  (Enterobius vermicularis) of NEMA�  TODE parasitic to humans, especially  children. Female pinworms may be  0.5 in.

Sept. 23, 1968, San Giovanni Rotondo) Italian priest. Born into  a devout Catholic family, he consecrated himself to Jesus at 5. At 15 he  joined the Capuchins and took the name Pio; in 1910 he became a priest.  That same year he received the stigmata for the first time. They were  healed, but he received them again in 1918; this time they remained with  him until his death. This and other signs of his holiness (perfume and,  reportedly, the ability to be in two places at once), drew growing num�  bers of pilgrims to him. He was canonized in 2002.</p><p>Piombo, Sebastiano del See Sebastiano del Piombo</p><p>Pioneer First series of unmanned U.S. deep-space probes. Pioneers 0-4  were all intended to be lunar missions, but only Pioneer 4 succeeded in  escaping Earth�s gravity (1964). Pioneer 1 was the first spacecraft launched  by NASA (1958). Pioneers 6-9 were successfully launched into solar  orbits (1965-68) to study the solar wind, solar magnetic field, and cosmic  rays. Pioneer 10, launched in 1972, was the first space probe to traverse the  asteroid belt and the first to fly by Jupiter (1973), where it discovered Jupi�  ter� s huge magnetic tail. It then became the first man-made object to exit the  solar system. Pioneer ll�s data and photographs (1979) enabled scientists  to identify two previously undiscovered moons and an additional ring  around Saturn and radiation belts in its magnetosphere. Two Pioneer Venus  spacecraft, the Orbiter and the Multiprobe (Pioneer 12 and 13, respec�  tively), reached Venus in 1978. The Orbiter observed the planet�s clouds  and atmosphere and mapped its surface by radar; the Multiprobe released  four instrument packages into the atmosphere at different locations.</p><p>pipa Vpe-'pa\ or p'i-p'a Short-necked Chinese lute.

A son  of Charles Martel, he became mayor of Neustria, Burgundy, and Provence  in 741 and de facto ruler of the Franks when his brother entered a mon�  astery in 747. With the backing of the pope, he deposed the last Merov�  ingian ruler, Childeric III, in 751 and was crowned king by the bishops  of his realm and, possibly, by the papal legate St. Boniface. Pippin was  crowned king in 754 by Pope Stephen II. The king bestowed on the pope  the Donation of Pippin and invaded Italy twice (754, 756) to protect the  pope from the Lombards. He also put down revolts in Saxony and Bavaria  and struggled to subdue rebellious Aquitaine. Pippin called several church  councils and promoted religious reform in the kingdom.</p><p>Pippin, Horace (b. Feb. 22, 1888, West Chester, Pa., U.S.�d. July 6,  1946, West Chester) U.S. folk painter. Pippin served in the infantry in  World War I, but he was wounded in 1918 and discharged with a partially  paralyzed right arm. His first large canvas was an eloquent protest against  war, End of the War: Starting Home (1931-34). His primary theme</p><p>became the African American experience, as seen in his series entitled  Cabin in the Cotton (mid 1930s) and his paintings of episodes in the lives  of the antislavery leader John Brown and Pres. Abraham Lincoln. After  the art world discovered Pippin in 1937, he received wide acclaim as the  greatest black painter of his time.</p><p>piracy Illegal act of violence, detention, or plunder committed for pri�  vate ends by the crew of a private ship (usually) against another ship on  the high seas. Air piracy (i.e., the hijacking of an aircraft) is a more recent  phenomenon. Piracy has occurred in all stages of history: the Phoenicians,  Greeks, and Romans engaged in it, as did the Vikings, Moors, and other  Europeans. It also occurred among Asian peoples. During the wars  between England and Spain in the late 16th century, treasure-laden Span�  ish galleons proceeding from Mexico into the Caribbean were a natural  target for pirates. In the 16th�18th centuries pirates from North Africa�s  Barbary Coast threatened commerce in the Mediterranean. The increased  size of merchant vessels, improved naval patrolling, and recognition by  governments of piracy as an international offense led to its decline in the  late 19th century. In the late 20th century incidents of piracy occurred  with increasing frequency in the seas of East and Southeast Asia.

The port and its �long walls,� fortified barriers connecting it with Athens,  were completed in the mid-5th century bc. The walls were destroyed by  Sparta at the end of the Peloponnesian War. Rebuilt under the Athenian  leader Conon in 393 bc, Piraeus was burned in 86 bc by the Roman com�  mander Lucius Cornelius Sulla. The city regained importance after ad 1834,  when Athens became capital of the newly independent Greece. The largest  port in Greece, it is the centre for all sea communication with the Greek  islands.</p><p>Pirandello, Luigi (b. June 28, 1867, Agrigento, Sicily, Italy�d. Dec.  10, 1936, Rome) Italian playwright  and novelist. He earned a doctorate  in philology at the University of  Bonn but turned to writing poetry,  short stories, and several novels,  including the successful The Late  Mattia Pascal (1904). His first major  play, Right You Are (if You Think You  Are) (1917), explored the relativity  of truth, a lifelong subject for Piran�  dello. Six Characters in Search of an  Author ( 1921) contrasted art and life;  it was followed by the tragedy Henry  IV (1922). His other plays include  Each in His Own Way (1924) and  Tonight We Improvise (1930). He  established the Teatro d�Arte in  Rome and toured the world with his company (1925-27). Recognized as  a major figure in 20th-century theatre, he was awarded the Nobel Prize  for Literature in 1934.</p><p>Piranesi X.pe-ra-'na-seX, Giovanni Battista or Giambattista  Piranesi (b. Oct. 4, 1720, Mestre, near Venice�d. Nov. 9, 1778, Rome,  Papal States) Italian draftsman, printmaker, architect, and art theorist. He  went to Rome at 20 as a draftsman for the Venetian ambassador. After  settling there in 1747, he developed a highly original etching technique  that produced rich textures and bold contrasts of light and shadow. His  many prints of Classical and post-Classical Roman structures contributed  to the growth of Classical archaeology and the Neoclassical ait movement.  He is best known today for his extraordinary series of imaginary prisons  (Carceri d�invenzione, 1745). His prints are among the most impressive  architectural representations in Western art.</p><p>piranha Vpo-'ra-no, po-'ran-yoN or caribe \k3-'re-be\ Any of several  species of deep-bodied, carnivorous fishes in the genus Serrasalmus (fam�  ily Characidae), abundant in rivers of eastern and central South America  and noted for voracity. The red-bellied piranha ( S . nattereri ) grows to 2 ft  (60 cm) long, but most species are smaller. Some species are silvery with  an orange belly and throat; others are almost completely black. All have  sharp, saw-edged teeth that close in a scissorlike bite. Traveling in groups,  they usually prey on other fishes, but red-bellied piranhas occasionally con�  verge on larger animals. Though generally scavengers, they are attracted to  the scent of blood and can quickly reduce even a large animal to a skeleton.</p><p>Luigi Pirandello.</p><p>COURTESY OF THE ITALIAN INSTITUTE, LONDON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1504 I Pirquet &#x25BA; piston and cylinder</p><p>Pirquet \pir-'ka\, Clemens, baron von (b.

Located on the Arno River, Pisa probably began as  an Etruscan town. It became a Roman colony c. 180 bc. A Christian bish�  opric by ad 313, it flourished during the Middle Ages as the principal  urban centre of Tuscany. Pisa�s participation in the Crusades made it a rival  of Genoa and Venice. It became part of the Kingdom of Italy in 1860. The  city was the scene of heavy fighting during World War II. It is now an  important railway junction. Its cathedral, the Leaning Tower of Pisa, and  other attractions, make it a tourist destination. It is the site of the Univer�  sity of Pisa (founded 1343) and the birthplace of Galileo.</p><p>Pisano \pi-'sa-no, pi-'za-n6\, Andrea or Andrea da Pontedera</p><p>(b. c. 1270-90, Pontedera, near Pisa�d. c. 1348/49, Orvieto, Papal States)  Italian sculptor and architect. He created the earliest of three bronze doors  for the Baptistery of the cathedral of Florence (1330-36). On Giotto�s  death in 1337, Andrea succeeded him as chief architect of the cathedral�s  bell tower, to which he added two stories adorned with panel reliefs. In  1347 he was appointed superintending architect of the cathedral of Orvi�  eto. One of the most important Italian sculptors of the 14th century, he is  known for his restrained style and skillful arrangement of figures.</p><p>Pisano, Giovanni (b. c. 1250, Pisa�d. after 1314, Siena?) Italian  sculptor and architect. His early work is similar to that of Nicola Pisano,  his father and teacher. About 1285 he began work on the facade of Sie�  na�s cathedral, whose lavish and ordered design and ornamentation  became the model for future Gothic facade decoration in central Italy. His  other great achievement, the Pistoia pulpit (c. 1298-1301), is character�  ized by extreme agitation, its figures, animals, drapery, and landscape  being wrenched into physically impossible configurations. His pulpit for  the Pisa cathedral (1302-10) is much more Classical, perhaps to accord  with Giotto�s monumental style, then in the ascendancy. Though regarded  as Italy�s only true Gothic sculptor, he never lost sight of the heritage of  Classical Rome.</p><p>Pisano, Nicola (b. c. 1220, Apulia?�d. 1278/84, Pisa?) Italian sculp�  tor. His work, along with that of his  son, Giovanni Pisano, created a new  sculptural style for the late 13th and  14th centuries in Italy. His greatest  work, the pulpit in the Baptistery of  Pisa Cathedral (1260), is extraordi�  nary in its assertion of a new style,  distinct from all its predecessors  though indebted to them. The work  draws on many motifs, including  Roman reliefs, early Christian fres�  coes and mosaics, and French Gothic  architecture and sculpture, but  assimilates them, creating a unified  whole that gave a new sense of direc�  tion to Tuscan art.</p><p>Pisces \'pl-,sez\ (Latin: �Fishes�) In  astronomy, the constellation lying  between Aries and Aquarius; in astrology, the twelfth sign of the zodiac,  governing approximately the period February 19-March 20. Its symbol  is two fish tied together. These are a reference to the Greek myth of Aph�  rodite and Eros, who jumped into a river to escape the monster Typhon and  were changed into fish. In another version of the myth, two fish carried  them to safety.</p><p>Pishpek See Bishkek</p><p>Pisidia \pi-'si-de-o\ Ancient region, southern Anatolia. Most of it was  composed of the Taurus Mountains, which provided refuge for a lawless  population that resisted successive conquerors. It was incorporated into  the Roman province of Galatia in the early 1st century ad and became</p><p>part of Lycia and Pamphylia under the emperor Vespasian in ad 74. Dio�  cletian included Pisidia in the diocese of Asia c. 297. During Byzantine  times it continued to be a region of revolt. By 1204 the Byzantine Empire  had lost control of the region to Turkish invaders.</p><p>pistachio \p3-'sta-she-,o\ Any of nine species of aromatic trees and  shrubs, some ornamental, that make up the genus Pistacia of the sumac  (or cashew) family, native to Eurasia, with one species in southwestern  North America and another in the Canary Islands. Commercial pistachio  nuts are seeds from the fruit of P. vera. They have a pleasing, mild, res�  inous flavour and are used extensively as food and for yellowish green  colouring in confections. The tree bears leaves with thick, wide, leathery,  featherlike leaflets and small fruit in clusters.</p><p>pistil Female reproductive part of a flower. Centrally located, the pistil  typically has a swollen base called the ovary, which contains the poten�  tial seeds (ovules). The stalk (style) arises from the ovary and has a pollen-  receptive tip, the stigma, which is variously shaped and often sticky. There  may be a single pistil, as in the lily, or several to many pistils, as in the  buttercup. Each pistil is constructed of one to many rolled leaflike struc�  tures, or carpels. Differences in the composition and form of the pistil are  useful in classifying flowering plants. See also stamen.</p><p>pistol Small firearm designed to be operated with one hand. The name  may derive from the city of Pistoia, Italy, where handguns were made as  early as the 15th century. It was originally a cavalry weapon. However,  because the firepower of pistols must be kept low in order to reduce them  to manageable weight, and because only skilled soldiers can shoot them  accurately beyond 10 yards, they have never been satisfactory military  weapons. In legal use, pistols are most frequently carried by police and  other security personnel and serve mainly as a defensive weapon of last  resort. Their compact size, low cost, and ease of operation make them a  common weapon in violent crime, so that pistols are a common object of  laws regulating the ownership of firearms. The two classes of pistol are  revolvers and automatics. Automatics have a mechanism, actuated by the  energy of recoil, that feeds cartridges from a magazine in the grip. See  illustration on opposite page.</p><p>piston and cylinder In mechanical engineering, a sliding cylinder  with a closed head (the piston) that moves up and down (or back and  forth) in a slightly larger cylindrical chamber (the cylinder) by or against  pressure of a fluid, as in an engine or pump. The cylinder of a steam engine  is closed by plates at both ends, with provision for the piston rod, which  is rigidly attached to the piston, to pass through one of the end cover  plates. The cylinder of an internal-combustion engine is closed at one end  by a plate called the head and open at the other end to permit free oscil�  lation of the connecting rod, which joins the piston to the crankshaft.</p><p>Adoration of the Magi (detail) by  Nicola Pisano, c. 1259-60; part of the  marble pulpit in the Baptistery at Pisa.</p><p>AUNARI/ART RESOURCE, NEW YORK</p><p>Pissarro \po-'sar-o\, (Jacob-Abraham-) Camille (b. July 10,  1830, St. Thomas, Danish West  Indies�d. Nov. 13, 1903, Paris,</p><p>France) West Indian-born French  painter. The son of a prosperous Jew�  ish merchant, he moved to Paris in  1855. His earliest canvases are  broadly painted figure paintings and  landscapes; these show the careful  observation of nature that was to  remain a characteristic of his art. In  1871 he took a house in Pontoise, in  the countryside outside Paris. These  surroundings formed the theme of  his art for some 30 years. Pissarro�s  leading motifs during the 1870s and  1880s were houses, factories, trees,  haystacks, fields, labouring peasants,  and river scenes. In these works,  forms do not dissolve but remain  firm, and colours are strong; during  the latter part of the 1870s his  comma-like brushstrokes frequently  recorded the sparkling scintillation</p><p>of light. These works were admired by the Impressionist artists; Pissarro  was the only Impressionist painter who participated in all eight of the  group�s exhibitions. Despite acute eye trouble, his later years were his  most prolific.</p><p>Self-portrait by Camille Pissarro, oil on  canvas, 1903; in the Tate Gallery, Lon�  don.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>pit bull terrier &#x25BA; Pitt I 1505</p><p>� MERRIAM-WEBSTER INC.</p><p>pit bull terrier or Staffordshire terrier Dog breed developed in  19th-century Britain for fighting other dogs in pits. It was created by  crossing the bulldog (which at the time was longer-legged and more agile)  with a terrier, possibly the fox terrier. Once known by such names as bull-  and-terrier and half-and-half, the pit bull is a stocky, muscular, unusually  strong dog with powerful jaws, standing 17-19 in.

It is the only inhabited island of the  Pitcairn island group, which also includes Henderson, Ducie, and Oeno  islands. It has an area of about 2 sq mi (5 sq km). Discovered in 1767 by  the British, it was uninhabited until 1790, when it was settled by muti�  neers from HMS Bounty, led by Fletcher Christian. Pitcairn was annexed  by Britain in 1838. The inhabitants were removed to Norfolk Island in  1856 because of overpopulation. Some returned to Pitcairn, and it is their  descendants who make up the present population, subsisting on fishing  and farming. In 1970 the British High Commissioner in New Zealand was  appointed Pitcairn�s governor.</p><p>pitch In music, position of a single sound in the complete range of sound;  this quality varies with the number of vibrations per second (hertz, Hz)  of the sounding body and is perceived as highness or lowness. A higher  pitch has a higher number of vibrations. In Western music, standard  pitches have long been used to facilitate tuning. A confusing variety of  pitches prevailed until the 19th century, when the continual rise in pitch  made some international agreement a matter of practical necessity. In  1939 the A above middle C was standardized as 440 Hz.

Pitchblende is found in granular masses and has a greasy lustre.  Three chemical elements were first discovered in pitchblende: uranium,  polonium, and radium. Deposits, frequently in association with uraninite  or with secondary uranium minerals, are known in the Czech Republic,  Britain, the Northwest Territories and Saskatchewan in Canada, and Ari�  zona, Colorado, Montana, New Mexico, and Utah in the U.S.</p><p>Pitcher, Molly (b. c. 1753�d. Jan. 22, 1832, Carlisle, Pa., U.S.) U.S.  patriot. Little is known of her early life, though she is thought to have been  Irish. In the American Revolution she accompanied her husband, William  Hays, a gunner, at the Battle of Monmouth (1778), where she carried  pitchers of water to wounded American soldiers, earning the nickname  �Molly Pitcher.� According to legend, after her husband collapsed from</p><p>the heat, she took his place at the cannon and served heroically through the  battle. In 1822 she was recognized for her heroism with a state pension.  Some historians attribute the act of replacing her husband at the cannon to  Margaret Corbin (1751-1800) in the attack on Fort Washington in 1776.</p><p>pitcher plant Any carnivorous plant with pitcher-, trumpet-, or urn�  shaped leaves. Several families  include pitcher plants: Nepenthaceae  (Old World pitcher plants), Cephal-  otaceae, Asclepiadaceae (milkweed  family), and especially Sarraceni-  aceae (New World pitcher plants,  particularly those in the eastern  North American genus Sarracenia).</p><p>Pitcher plants inhabit bogs, swamps,  wet or sandy meadows, or savannas  where the soils are water-saturated,  acidic, and deficient in nitrates or  phosphates. Their unusual tubular  leaves have a series of nectar-  secreting glands that extend from the  lip down into the interior and attract  insects. Once in the plant, the prey  tumbles down into a liquid pool and  drowns, after which an enzyme  secreted within the leaf digests it, releasing nitrates and other nutrients,  which supplement the meager nutrient supply of bogs. Most pitcher plants  produce pitcher-shaped, insect-catching leaves in the spring and tubeless  leaves in the fall. Their flowers are showy and have an agreeable scent.</p><p>pitot tube \'pe-,to\ Instrument for measuring the velocity (speed) of a  flowing fluid. Invented by Henri Pitot (1695-1771), it consists of a tube  with a short, right-angled bend, which is placed vertically in a moving  fluid with the mouth of the bent part directed upstream; the pressure, mea�  sured with an attached device, depends on the fluid flow and can be used  to calculate the velocity. Pitot tubes are used to measure airspeed in wind  tunnels and aboard aircraft in flight; they are also used to measure the  flow of liquids (see flow meter).</p><p>Pitt, William, the Elder later 1st earl of Chatham (b.

He entered Par�  liament in 1735 and provoked controversy with his maiden speech, which  criticized the ministry of Robert Walpole. With the outbreak of the Seven  Years' War, he was named secretary of state and became virtual prime min�  ister. His leadership brought many British victories that greatly extended  the British Empire. His wide popular appeal led to the nickname �the Great  Commoner,� though he was disliked by many in government for his high�  handedness. He resigned in 1761 when the cabinet refused to declare war  on Spain. He became a champion of liberty and spoke in favour of Ameri�  can colonial resistance to the Stamp Act. He formed another government in  1766, in which he served as lord privy seal, but he resigned in 1768 because  of ill health.

In the 19th cen�  tury it developed rapidly as a steel-manufacturing centre. The American  Federation of Labor began there in 1881 (see AFL-CIO). The second-  largest city in the state, it is the centre of an urban industrial complex that  includes several neighbouring cities.

It is home to the University of Pittsburgh,  Carnegie Mellon University, and other educational institutions.</p><p>Pittsburgh Platform Manifesto of Reform Judaism, drawn up in 1885  by a conference of rabbis chaired by Isaac Mayer Wise in Pittsburgh, Pa.  It declared that Judaism taught the highest conception of God, but it rec�  ognized the efforts of other religions to grasp the truth. The Bible was  understood as the primary instrument of moral and religious instruction  even though it reflected the primitive ideas of the time of its composition.  It rejected the Mosaic and rabbinic laws regulating diet and dress, accept�  ing only those laws that elevate the spirit. The Pittsburgh Platform looked  forward to the messianic kingdom and accepted the immortality of the  soul but not resurrection of the body. It advocated social justice and uni�  versal moral reform and maintained that Judaism was an evolving reli�  gion. It remained the official philosophy of the U.S. Reform movement  until 1937, when the Columbus Platform moved Reform Judaism back to  a more traditional position.</p><p>pituitary \p9-'tu-3-,ter-e\ gland or hypophysis \hI-'paf-3-s9s\  Endocrine gland lying on the underside of the brain.

It is now popular world�  wide.</p><p>PKK See Kurdistan Workers Party  PKU See PHENYLKETONURIA</p><p>PL Kyodan \'pe- , el- , ky6-dan\ in full Perfect Liberty Kyodan Reli�  gious group founded in Japan by Miki Tokuchika in 1946 as a revival of  his father�s group, Hito-no-michi. Unaffiliated with any of the major reli�  gious traditions of Japan, it teaches that the goal of human life is joyful  self-expression. Misfortune and suffering come from forgetting God, but  the believer may pray that his troubles be transferred to the patriarch, who  is strengthened for vicarious suffering by the group�s collective prayers.  Today PL Kyodan claims more than 2.5 million adherents worldwide. The  sect�s headquarters are at Habikino, near Osaka.</p><p>placenta \pb-'sen-t3\ Organ in most mammals that develops in the uterus  along with a fetus to mediate metabolic exchange. The umbilical cord  attaches it to the fetus at the navel. Nutrients and oxygen in the mother�s  blood pass across the placenta to the fetus, and metabolic wastes and car�  bon dioxide from the fetus cross in the other direction; the two blood sup�  plies do not mix. Other substances (e.g., alcohol or drugs) in the mother�s  blood can also cross the placenta, with effects including congenital disor�  ders and drug addiction in the newborn (see fetal alcohol syndrome); some  microorganisms can cross it to infect the fetus, but so do the mother�s  antibodies. The placenta, weighing a pound or more at the end of preg�  nancy, is expelled at parturition. Some animals eat it as a source of nutri�  ents; in some species this stimulates lactation.</p><p>placer deposit Natural concentration of heavy minerals caused by the  effect of gravity on moving particles. When heavy, stable minerals are  freed from their matrix by weathering processes, they are slowly washed  downslope into streams that quickly winnow the lighter matrix. Thus the  heavy minerals become concentrated in stream, beach, and lag (residual)  gravels and constitute workable ore deposits. Minerals that form placer  deposits include gold, platinum, cassiterite, magnetite, chromite, ilmenite,  rutile, native copper, zircon, monazite, and various gemstones.</p></section><section><p>placer mining Oldest method of recovering gold from alluvial depos�  its. It takes advantage of gold�s high density, which causes it to sink more  rapidly from moving water than the lighter siliceous materials with which  it is found. Panning, used by 19th-century miners, employed a pan in  which a few handfuls of the gold-bearing soil or gravel and a large amount  of water were placed; by swirling the pan�s contents, the miner washed  the siliceous material over the side, leaving the gold and heavy materials  behind. Dredging is the most important placer-mining method today. Used  worldwide is the bucket-ladder dredge, with its continuous chain of buck�  ets rotating around a rigid adjustable frame called the ladder. In sluicing,  a slightly sloping wooden trough called a box sluice, or a ditch cut in hard  gravel or rock called a ground sluice, is used as a channel along which  gold-bearing gravel is carried by a stream of water. Riffles placed trans�  versely along the bottom of the sluice cause the water to eddy into small  basins, retarding the current so that gold may settle.</p><p>Placid, Lake See Lake Placid</p><p>plagioclase \ , pla-je-o- l klas\ Any member of the series of abundant  feldspar minerals that usually occur as light- to medium-grey-coloured,</p><p>transparent to translucent grains or crystals. Plagioclase ranges in com�  position from albite to anorthite. It is used in the manufacture of glass and  ceramics; iridescent varieties are valued as gemstones. The primary  importance of plagioclase, however, derives from its role as a rock�  forming mineral.</p><p>plague \'plag\ Infectious fever caused by the bacterium Yersinia pestis ,  carried by the rat flea. It usually spreads to humans only when the flea  runs out of rodent hosts. It takes three forms. Bubonic, the mildest, has  characteristic swollen lymph nodes (buboes) and is spread only by the flea.  It accounts for three-fourths of plague cases. Pneumonic plague has exten�  sive lung involvement and is spread in droplets from the lungs; it is often  fatal in three or four days without treatment. In septicemic plague, bac�  teria overwhelm the bloodstream and often cause death within 24 hours,  before other symptoms have a chance to develop. In the 14th century,  plague ravaged Europe and Asia and was called the Back Death. Plague  does not respond to penicillin, but other antibiotics are effective. Sanitary  measures against fleas and rodents, quarantine, and extreme caution in  handling infectious materials help to suppress epidemics. A vaccine can  prevent plague.</p><p>plaice Commercially valuable European fatfish ( Pleuronectes platessa).  At most 36 in. (90 cm) long, the  plaice normally has both eyes on the  right side of the head and four to  seven bony bumps near its eyes. It is  brown with red or orange spots. The  American plaice ( Hippoglossoides  platessoides) is found in both Europe  (where it is called the rough dab) and  the U.S. It is reddish or brownish and  grows to about 24 in. (60 cm) long.</p><p>plain Any relatively level area of  the Earth�s surface that exhibits  gentle slopes and small local relief (differences in elevation). Occupying  slightly more than one-third of the terrestrial surface, plains are found on all  continents except Antarctica. Some are tree-covered, and others are grassy.  Still others support scrub brush and bunch grass, and a few are nearly  waterless deserts. With certain exceptions, plains have become the sites of  major centres of population, industry, commerce, and transportation.</p><p>Plain, the French la Plaine In the French Revolution, the centrist  deputies in the National Convention. They formed the majority of the  assembly�s members and were essential to the passage of any measures.  Their name derived from their place on the floor of the assembly; above  them sat the members of the Mountain, or Montagnard. Led by Emmanuel-  Joseph Sieyes, the Plain initially voted with the moderate Girondins but later  joined the Montagnards in voting for the execution of Louis XVI. In 1794  they helped overthrow Maximilien de Robespierre and other extreme Jacobins  (see Jacobin Club).</p><p>Plain of Esdraelon See Plain of Esdraelon  Plain of Reeds See Plain of Reeds  Plain of Sharon See Plain of Sharon</p><p>Plains Indian Any member of various Native American tribes that for�  merly inhabited the Great Pains of the U.S. and southern Canada. Plains  Indians are popularly regarded as the typical American Indians. They were  essentially big-game hunters, the buffalo being a primary source of food  and equally important as a source of materials for clothing, shelter, and  tools. Until supplanted by the white settlers from the 16th century onward,  the Plains Indians occupied the area between the Mississippi River and  the Rocky Mountains, which includes portions of both the United States  and Canada. It is a vast grassland stretching from northern Alberta and  Saskatchewan in Canada to the Rio Grande border of Texas. The Arapaho,  Assiniboin, Backfoot, Cheyenne, Comanche, Plains Cree, Crow, Hidatsa,  Kiowa, Mandan, Osage, Pawnee, and Sioux are Plains Indians.</p><p>Plains of Abraham See Plains of Abraham</p><p>planarian \pta-'nar-e-3n\ Any of about 3,000 species of widely distrib�  uted, mostly free-living fatworms of the family Planariidae and related  families (class Turbellaria), usually found in freshwater but also in marine  and terrestrial environments. The soft, ciliated body is leaf-shaped when  elongated. The spade-shaped head has two eyes and sometimes tentacles.  The tail is pointed.

He  studied at the Universities of Munich and Kiel, then became professor of  theoretical physics at the University of Berlin (1889-1928). His work on  the second law of thermodynamics and blackbody radiation led him to  formulate the revolutionary quantum theory of radiation, for which he  received a Nobel Prize in 1918. He also discovered the quantum of action,  now known as Planck�s constant, h. He championed Albert Einstein�s spe�  cial theory of relativity, but he opposed the indeterministic, statistical  worldview introduced by Niels Bohr, Max Born, and Werner Heisenberg  after the advent of quantum mechanics. As the influential president of the  Kaiser Wilhelm Society (later the Max Planck Society) until his resigna�  tion in 1937, he appealed to Adolf Hitler to reverse his devastating racial  policies. His son was later implicated in the July Plot against Hitler and  was executed.</p><p>plane tree Any of ten species of large trees that make up the genus  Plcitanus, sole genus of the family Platanaceae, native to North America,  eastern Europe, and Asia. Plane trees are planted widely in cities for their  resistance to diseases and to air pollution and because they grow rapidly  and furnish quick shade. They are characterized by scaling bark; large,  deciduous, usually lobed leaves; and globular heads of flower and seed.  Ball-shaped smooth or bristly seed clusters, which dangle singly and often  persist after leaf fall, are key identifiers. Winter bark is patchy and pic�  turesque; as the outer bark flakes off, inner bark shows shades of white,  gray, green, and yellow.</p><p>planer Metal-cutting machine tool in which the workpiece is firmly  attached to a horizontal table that moves back and forth under a single�  point cutting tool. The tool-holding device is mounted on a crossrail so that  the tool can be moved across the table in small sideward movements. Since  the cutting tool can be moved at almost any angle, a wide variety of grooves  and surfaces can be generated. Mechanical planers, or surfacers, are also  used to smooth wood to an even thickness. Planers perform the same opera�  tions as shapers but can machine workpieces up to 50 ft (15 m) long.</p><p>planet Any large body orbiting the Sun or another star (see planets of  other stars); comets, asteroids, meteoroids (see meteor), and natural satel�  lites are excluded. The word comes from the Greek for �wanderer,�  because their positions change relative to those of the stars. The nine  major planets known to revolve around the Sun, in order of increasing  distance, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Nep�  tune, and Pluto. The first four are called terrestrial planets and the next  four Jovian planets. Pluto, distinct from either group, resembles a giant  comet or one of the icy satellites of the Jovian planets. The terrestrial  p_ planets are less than 8,000 mi (13,000 km) in diameter and rocky, with</p><p>comparatively thin or negligible atmospheres. The Sun�s heat is thought  wm to have prevented the abundant gases in the original solar nebula from</p><p>condensing in them. The Jovian planets formed farther out, where the  gases were cool enough to condense, so the planets grew very massive  tm and accumulated huge atmospheres of light gases, mainly hydrogen and</p><p>y helium. Called gas giants, the Jovian planets appear to be similar in struc�</p><p>ture; none has an accessible surface. Pluto is by far the smallest body tra�  ditionally called a major planet, although many astronomers now consider  it the largest known member of the Kuiper belt. Additional bodies rivaling  Pluto in size may exist in this region of the solar system; one about half  its size was discovered in 2002. The term minor planet is sometimes used  (less now than formerly) to refer to any of the asteroids that lie between  the terrestrial and Jovian planets. In astrology great importance is placed  on the planets� positions in the 12 constellations of the zodiac. See also  planetesimal; solar system.</p><p>Planet X Supposed distant planet of the solar system, hypothesized on  the basis of calculations of effects on the orbits of Uranus and Neptune.  The term was first used by Percival Lowell c. 1905, and though his pre�  diction eventually resulted in the discovery of Pluto (1930), Pluto�s mass  was insufficient to explain the apparent perturbations of Uranus and Nep�  tune. Proposals and searches for other planets beyond Neptune or Pluto  continued sporadically during the remainder of the 20th century. How�  ever, Voyager spacecraft data gathered about the masses of the outer plan�  ets indicate that no additional large bodies are needed to explain the  planets� observed orbits. See also Kuiper belt.</p><p>planetarium Institution devoted to popular education in astronomy and  related fields, especially space science, whose main teaching tool is a  hemispheric screen onto which images of celestial objects as seen from  Earth are projected from an instrument also known as a planetarium, or  planetarium projector. Major planetariums have extensive exhibit space,  museum collections, sizable staffs, projection domes 80 ft (25 m) or more  across, and seating capacities of over 600.</p><p>planetary nebula Any of a class of bright NEBULAe that may some�  what resemble planets when viewed through a small telescope but are, in  fact, expanding shells of luminous gas around dying stars. A planetary  nebula is the outer envelope shed by a red giant star not massive enough  to become a supernova. Instead, the star�s intensely hot core becomes  exposed (see white dwarf star) and ionizes the surrounding shell of gas,  which is expanding at tens of miles per second.</p><p>planetesimal N.pla-no-'te-so-moH One of a class of hypothetical bod�  ies that joined to form the planets after condensing from dust and gas early  in the history of the solar system. According to the nebular hypothesis, a  rotating cloud of interstellar dust and gas underwent gravitational con�  traction, eventually forming a solar nebula comprising a disk of matter  with a central hub. As the disk contracted further, clumps of dust left  behind in its midplane coalesced successively into bodies the size of  pebbles and boulders and then into planetesimals up to several hundred  miles across. These then combined under the force of gravity to form pro�  toplanets, precursors of the current planets.</p><p>planets of other stars or extrasolar planets Planets that orbit  stars other than the Sun. The existence of extrasolar planets, many light-  years from Earth, was confirmed in the early 1990s with the detection of  three bodies circling a pulsar. The first planet revolving around a more  sunlike star, 51 Pegasi, was reported in 1995. Within a decade over 100  stars with one or more planets were known. Current detection methods,  based on the planets� gravitational effects on the stars they orbit, have  revealed only planets much more massive than Earth; some are several  times the size of Jupiter. A number of them have highly elliptical orbits,  and many are closer to their stars than Mercury is to the Sun. These find�  ings have raised questions regarding astronomers� ideas of how Earth�s  solar system formed and how typical it is.</p><p>plankton Marine and freshwater organisms that, because they are  unable to move or are too small or too weak to swim against water cur�  rents, exist in a drifting, floating state. Plankton is the productive base of  both marine and freshwater ecosystems, providing food for larger animals  and indirectly for humans, whose fisheries depend on plankton. As a  human resource, plankton has only begun to be developed and used. The  plantlike community of plankton is called phytoplankton, and the animal�  like community is called zooplankton, but many planktonic organisms are  better described as protists. Most phytoplankton serves as food for zoo�  plankton, but some of it is carried below the light zone. Zooplankton is  used directly as food by fish (including herring) or mammals (including  whales), but several links on the food chain usually have been passed  before plankton is available for human consumption.</p><p>plant Any organism in the kingdom Plantae, consisting of multicellu�  lar, eukaryotic life forms (see eukaryote) with six fundamental character�  istics: photosynthesis as the almost exclusive mode of nutrition, essentially  unlimited growth at meristems, cells that contain cellulose in their walls and  are therefore somewhat rigid, the absence of organs of movement, the  absence of sensory and nervous systems, and life histories that show  alternation of generations. No definition of the kingdom completely  excludes all nonplant organisms or even includes all plants. Many plants,  for example, are not green and thus do not produce their own food by  photosynthesis, being instead parasitic on other living plants (see parasit�  ism). Others obtain their food from dead organic matter. Many animals  possess plantlike characteristics, such as a lack of mobility (e.g., sponges)  or the presence of a plantlike growth form (e.g., some corals and bryo-  zoans), but in general such animals lack other plant characteristics. Some  past classification systems (see taxonomy) placed difficult groups such as  protozoans, bacteria, algae, slime molds, and fungi (see fungus) in the plant  kingdom, but structural and functional differences between these organ�  isms and plants have convinced most scientists to classify them elsewhere.</p><p>plant virus Any of various viRUSes that can cause plant disease (e.g., the  tobacco mosaic virus). Plant viruses are economically important because  many of them infect crop and ornamental plants. Numerous plant viruses  are rodlike and can be extracted readily from plant tissue and crystallized.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Plantagenet &#x25BA; plastics I 1509</p><p>Most lack the fatty membrane found in many animal viruses, and all con�  tain RNA.

Symptoms of  virus infection include colour changes, dwarfing, and tissue distortion.  The appearance of streaks of colour in certain tulips is caused by a virus.  See also reovirus.</p><p>Plantagenet Nplan-'ta-jo-natV House of or House of Anjou</p><p>Van-jii\ Royal house of England (1154-1485) that provided 14 kings,  including six from the cadet houses of Lancaster and York. The line  descended from Geoffrey, count of Anjou (died 1151), and the empress  Matilda, daughter of the English king Henry I. Some historians apply the  name House of Anjou, or Angevin dynasty, to only Henry II, Richard I, and  John, and label their successors, including Edward I, Edward II, and Edward  III, as Plantagenets. The name may have originated as a nickname (Plante-  geneste) for Count Geoffrey, who planted broom shrubs (Latin Genista )  to improve his hunting covers. The Wars of the Roses saw the defeat of  the last Plantagenet king, Richard III, in 1485. The legitimate line ended  with Edward of Warwick (died 1499).</p><p>plantain Tall plant ( Musa paradisiaca) of the banana family that is  closely related to the common banana (M. sapientum). Believed to have  originated in Southeast Asia, the plantain grows 10-33 ft (3-10 m) tall  and has a conical false �trunk� formed by the leaf sheaths of its spirally  arranged, long, thin leaves. The green-coloured fruit is larger than that of  the banana and contains more starch. Because the starch is maximal before  the fruit ripens, the fruit is not eaten raw but is boiled or fried, often with  coconut juice or sugar as flavouring. It may also be dried for later use in  cooking or ground for use as meal, which can be further refined to a flour.  The plantain is a staple food and beer-making crop for East African  peoples and is also eaten in the Caribbean and Latin America.</p><p>plantain \'plan-t 3 n\ Any of about 265 species of familiar garden, lawn,  and roadside weeds in the genus Plantago of the family Plantaginaceae.  Distinctively, the leaves lack a proper blade. What appears to be a blade  is an expanded petiole (leafstalk), with several parallel main veins, emerg�  ing at the base of the stalk. Small flowers are borne in spikes or heads  atop long leafless stalks. The greater plantain (P. major) provides seed  spikes for bird food. Ribwort, or English, plantain (P. lanceolata ) and  hoary plantain (P media) are troublesome weeds. Some species have been  useful in medicine (e.g., as an ingredient in laxatives).</p><p>plantation walking horse See Tennessee walking horse</p><p>Plante, (Joseph) Jacques (Omer) (b.

He was an  integral member of the powerful Montreal Canadiens team that won a  record five successive Stanley Cups (1956-60). He was the first goalie to  wear a protective face mask (1959). Honoured throughout his 18-year  NHL career, he was one of the most successful of all NHL goaltenders.</p><p>Planudes \pla-'nu-dez\, Maximus orig. Manuel Planudes (b.</p><p>1260, Nicomedia, Byzantine Empire�d. c. 1310, Constantinople) Greek  Orthodox scholar, anthologist, and polemicist. He established a school in  Constantinople that gained a strong reputation for its humanities curricu�  lum. His Greek translations of Latin philosophy and literature and of Ara�  bic mathematics publicized these areas of learning throughout the Greek  Byzantine cultural world. Though chiefly known for his theological writ�  ings, he made a distinctive contribution to the history of Greek literature  with his revision of the Greek Anthology, a collection of Greek prose and  poetry c. 700 bc-ad 1000.</p><p>plasma Vplaz-m9\ Liquid part of blood (including dissolved chemicals  but not the cells and platelets). This straw-coloured fluid serves as the  blood�s transport medium, helps maintain blood pressure, distributes body  heat, and maintains the pH balance in the bloodstream and body. More  than 90% consists of water, about 7% proteins, and the rest other sub�  stances, including waste products of metabolism. Important plasma proteins  include albumin, coagulation factors, and globulins, including gamma globu�  lin and a hormone that stimulates erythrocyte formation. Serum is the liq�  uid part of the blood that remains after clotting.</p><p>plasma Electrically conducting medium in which there are roughly  equal numbers of positively and negatively charged particles, produced  when the atoms in a gas become ionized (see ionization). Plasma is some�  times called the fourth state of matter (the first three being solid, liquid,  and gas). A plasma is unique in the way it interacts with itself, with elec�</p><p>tric and magnetic fields, and with its environment. It can be thought of as  a collection of ions, electrons, neutral atoms and molecules, and photons  in which some atoms are being ionized at the same time as electrons are  recombining with other ions to form neutral particles, while photons are  continuously being produced and absorbed. It is estimated that more than  99% of the matter in the universe exists in the plasma state.</p><p>plasmid Vplaz-madN Genetic element not contained within a chromo�  some. It occurs in many bacterial strains. Plasmids are circular DNA mol�  ecules that replicate independently of the bacterial chromosome. They are  not essential for the bacterium but may give it a selective advantage. Some  plasmids determine the production of proteins that can kill other bacte�  ria; others make bacteria resistant to antibiotics. Plasmids are extremely  valuable tools in the fields of molecular biology and genetics, specifically  in the area of genetic engineering.</p><p>plasmodium \plaz-'mo-de-9m\ Any of the parasitic protozoans that  make up the genus Plasmodium, the cause of malaria. Infecting red blood  cells in mammals, birds, and reptiles, plasmodia occur worldwide, espe�  cially in tropical and temperate zones. They are transmitted to humans by  the bite of the Anopheles mosquito. From the bloodstream, young plas�  modia enter liver cells, where they divide and form an adult stage that is  then released back into the bloodstream and infects red blood cells. Rapid  division of the parasites results in the destruction of the red blood cells,  which release toxins that cause the periodic chill and fever cycles typical  of malaria.</p><p>plaster of paris Quick-setting gypsum plaster consisting of a fine white  powder, calcium sulfate hemihydrate, which hardens when moistened and  allowed to dry. It is made by heating gypsum to 250-360�F (120-180�C).  Used since ancient times, plaster of paris is so called because of its prepa�  ration from the abundant gypsum found in Paris. It is used to make molds  and casts for ceramics and sculptures, to precast and hold ornamental  plasterwork on ceilings and cornices, and for orthopedic bandages (casts).  In medieval and Renaissance times, gesso (plaster of paris mixed with  glue) was applied to wood panels, plaster, stone, or canvas to provide the  ground for tempera and oil painting.</p><p>plastic surgery Surgery to correct disfigurement, restore function, or  improve appearance. It may involve reshaping or moving tissues to fill a  depression, cover a wound, or improve appearance. Cosmetic surgery  solely to improve appearance is not the main focus of plastic surgery. It  is utilized after disfigurement by bums or tumour removal or for recon�  structive work, and it may involve hiding incisions in skin folds or using  buried sutures to hold wounds closed. Reconstructive plastic surgery cor�  rects severe functional impairments, fixes physical abnormalities, and  compensates for tissue lost to trauma or surgery. Microsurgery and com�  puterized diagnostic imaging techniques have revolutionized the field.</p><p>plasticity Ability of certain solids to flow or to change shape perma�  nently when subjected to STRESSes between those that produce temporary  deformation, or elastic behaviour, and those that cause failure of the mate�  rial, or rupture (see fracture). Plasticity allows a solid under the action of  outside forces to become permanently deformed without rupturing; elas�  ticity enables a solid to return to its original shape after the load is removed.  Plastic deformation occurs in many metal-forming processes (rolling,  pressing, forging, wire drawing) and in geologic processes (rock folding  and rock flow within the Earth under extremely high pressures and at  elevated temperatures).</p><p>plastics Polymers that can be molded or shaped, usually by heat and  pressure. Most are lightweight, transparent, tough organic compounds that  do not conduct electricity well. They fall into two classes: Thermoplas�  tics (e.g., polyethylene, polystyrene) can be melted and formed again and  again; thermosetting plastics, or thermosets (e.g., polyurethane, epoxy),  once formed, are destroyed rather than melted by heating. Few plastics  contain only the polymer resin; many also contain plasticizers (to change  the melting point and make them softer), colorants, reinforcements, and  fillers (to improve mechanical properties such as stiffness), and stabiliz�  ers and antioxidants (to protect against aging, light, or biological agents).  Traditional plastics are not biodegradable (see biodegradability); recycling  of plastics, especially thermoplastics, has become an important industry,  and the development of low-cost biodegradable plastics and plastic sub�  stitutes is a significant pursuit of industrial research. Major commercial  uses of plastics include cars, buildings, packaging, textiles, paints, adhe�  sives, pipes, electrical and electronic components, prostheses, toys,  brushes, and furniture. Common plastics include polyethylene terephtha-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1510 I Plata &#x25BA; platelet</p><p>rigidly connected to their respective plates and move as the plates move, a few inches a year.</p><p>� MERRIAM-WEBSTER INC.</p><p>late, or PET (beverage bottles), PVC (pipes and hoses), foamed polysty�  rene, or Styrofoam (insulated food containers), and Lucite (shatterproof  windows).

Plataea was the scene of  the Greek victory over the invading Persians in the Battle of Plataea (479  bc). It was destroyed by the Spartans in 427 bc but was rebuilt under the  Macedonian kings Philip II and Alexander the Great as a symbol of Greek  courage in resisting Persia.</p><p>Plataea, Battle of (479 bc) Battle between Greek and Persian forces  near Plataea (modern Plataiaf) in Boeotia on the slopes of Mount Cith-  aeron. A largely Spartan force, including helots, defeated the Persian army  of Xerxes I, led by Mardonius; the victory marked this battle as the final  Persian attempt to invade mainland Greece.</p><p>plate tectonics Theory that the Earth�s lithosphere (the crust and upper  portion of the mantle) is divided into about 12 large plates and several  small ones that float on and travel independently over the asthenosphere.  The theory revolutionized the geological sciences in the 1960s by com�  bining the earlier idea of continental drift and the new concept of seafloor  spreading into a coherent whole. Each plate consists of rigid rock created  by upwelling magma at oceanic ridges, where plates diverge. Where two</p><p>plates converge, a subduction zone forms, in which one plate is forced  under another and into the Earth�s mantle. The majority of the earthquakes  and volcanoes on the Earth�s surface occur along the margins of tectonic  plates. The interior of a plate moves as a rigid body, with only minor flex�  ing, few earthquakes, and relatively little volcanic activity.</p><p>plateau Extensive area of flat upland, usually bounded by an escarp�  ment on all sides but sometimes enclosed by mountains. Plateaus are  extensive, and together with enclosed basins they cover about 45% of the  Earth�s land surface. The essential criteria for a plateau are low relative  relief and some altitude. Low relief distinguishes plateaus from mountains,  although their origin may be similar. Plateaus, being high, often create  their own local climate; the topography of plateaus and their surround�  ings often produce arid and semiarid conditions.</p><p>Plateau Indian Any member of various North American Indian  peoples that inhabited the high plateau between the Rocky Mountains on  the east and the Cascade Range on the west. The Plateau culture was not  stable. By ad 1200-1300 the �classic� phase had emerged, characterized  by permanent winter villages with semi-subterranean earth lodges along  the main rivers and by summer camps with mat-covered conical lodges  in the meadows. During the centuries that followed, the Plateau area was  influenced by cultural elements from the highly specialized Northwest  Coast culture. Part of this diffusion was possibly brought about by a Chi�  nook group, the Wishram, who migrated from the coast into the Cascade  Mountains. During the 18th century there were influences from the east.  The Shoshone had acquired horses by that time and furnished their clos�  est neighbours on the Plains and the Plateau with horses.

The name (which  comes from a comparison to the intricate work of silversmiths) came to  be generally applied to late Gothic and early Renaissance Spanish archi�  tecture, which was characterized by minutely detailed relief ornament  derived from Moorish, Gothic, and Italian Renaissance sources and  applied without regard for structure. Favourite motifs for this ornament  included twisted columns, heraldic escutcheons, and sinuous scrolls; clus�  ters of ornament often contrasted with broad expanses of flat wall surface.  Over time, the style evolved so that ornamentation became purer and more  unified with the overall structure. Outstanding examples of the style  include Diego de Siloe�s Granada Cathedral (1528�43), Diego de Riano�s  work on the Seville Cathedral (c. 1530), and Rodrigo Gil de Hontanon�s  facade of the University of Alcala de Henares (1541-53).</p><p>platform tennis Variation of paddle tennis, played on a platform  enclosed by a wire fence. It was devised in 1928 in Scarsdale, N.Y., U.S.  The short-handled oval paddles are made of perforated plywood; the balls  are made of sponge rubber. The rules are the same as for tennis, except  that balls may be played off back or side walls after first striking inside  the court.</p><p>Plath, Sylvia (b. Oct. 27, 1932, Boston, Mass., U.S.�d. Feb. 11. 1963,  London, Eng.) U.S. poet. The daughter of an entomologist, Plath was  driven to excel as a writer from an early age and published her first poem  at age eight. At Smith College she made an early suicide attempt and sub�  mitted to electroshock treatment. While attending Cambridge University  on a Fulbright grant, she married the poet Ted Hughes. After their sepa�  ration, she committed suicide at age 30. Though she was not widely rec�  ognized in her lifetime, her reputation grew rapidly afterward; by the  1970s she was considered a major contemporary poet. Her works, often  confessional and preoccupied with alienation, death, and self-destruction,  include the volumes The Colossus (1960), Ariel (1965), and The Collected  Poems (1981, Pulitzer Prize) and a semiautobiographical novel. The Bell  Jar (1963).</p><p>plating Coating a metal or other material, such as plastic or china, with  a hard, nonporous metallic surface to improve durability and beauty. Early  plated goods (�old Sheffield plate�) are made by the process invented by  Thomas Boulsover, and consist of a sandwich of copper between two lay�  ers of silver. Today surfaces such as gold, silver, stainless steel, palladium,  copper, and nickel are applied by dipping an object into a solution con�  taining the desired surface material, which is deposited by chemical or  electrochemical action (see electroplating). Much plating is done for deco�  rative purposes, but still more is done to increase the durability and cor�  rosion resistance of softer materials. Most automotive parts, appliances,  housewares and flatware, hardware, plumbing and electronic equipment,  wire goods, aircraft and aerospace products, and machine tools are plated  for durability. See also galvanizing, ternepiate, tinplating.</p><p>platinum Metallic chemical element, one of the transition elements,  chemical symbol Pt, atomic number 78. A very heavy, silvery white pre�  cious metal, it is soft and ductile, with a high melting point (3,216 �F  [1,769 �C]) and good resistance to corrosion and chemical attack. Small  amounts of iridium are commonly added for a harder, stronger alloy that  retains platinum�s advantages. Platinum is found usually as alloys of  80-90% purity in placer deposits or more rarely combined with arsenic or  sulfur. It is indispensable in high-temperature laboratory work for elec�  trodes, dishes, and electrical contacts that resist chemical attack even  when very hot. Platinum is used in dental alloys and surgical pins; alloys  typically containing 90-95% platinum are used in expensive jewelry. The  international primary standard for the kilogram is made of 90% platinum,  10% iridium. Platinum has valence 2 or 4 in its compounds, which include  many coordination complexes. It and some compounds are useful cata�  lysts, particularly for hydrogenation and in catalytic converters for reduc�  ing automobile emissions.</p><p>Plato \'pla-to\ orig. Aristocles (b. 428/427, Athens, or Aegina,  Greece�d. 348/347 bc, Athens) Greek philosopher, who with his teacher  Socrates and his student Aristotle laid the philosophical foundations of  Western culture. His family was highly distinguished; his father claimed  descent from the last king of Athens, and his mother was related to Cri-  tias and Charmides, extremist leaders of the oligarchic terror of 404. Plato  (whose acquired name refers to his broad forehead, and thus his range of</p><p>knowledge) must have known Socrates from boyhood. After Socrates was  put to death in 401, Plato fled Athens for Megara, then spent the next 12  years in travel. Upon his return, he founded the Academy, an institute of  scientific and philosophical research, where Aristotle was one of his stu�  dents. Building on but also departing from Socrates� thought, he devel�  oped a profound and wide-ranging philosophical system, subsequently  known as Platonism. His thought has logical, epistemological, and meta�  physical aspects, but much of its underlying motivation is ethical. It is  presented in his many dialogues, in most of which Socrates plays a lead�  ing role. See also Neoplatonism.</p><p>Platonic solid also known as regular polyhedron Geometric solid  all of whose faces are identical regular polygons and all of whose angles  are equal. There are only five such polyhedrons. The cube is constructed  from the square, the dodecahedron from the regular pentagon, and the  tetrahedron, octahedron, and icosahedron (with 20 faces) from the equi�  lateral triangle. They are known as the Platonic solids because of Plato�s  attempt to relate each to one of the five elements that he believed formed  the world.</p><p>Platonism Vpla-ta-.ni-zsmV Any philosophy that embodies some major  idea of Plato�s, especially in taking abstract forms as metaphysically more  basic than material things. Though there was in antiquity a tradition about  Plato�s �unwritten doctrines,� Platonism then and later was based primar�  ily on a reading of the dialogues. It is characterized by an intense con�  cern for the quality of human life�always ethical, often religious, and  sometimes political, based on a belief in unchanging and eternal realities  (the Platonic Forms), independent of the changing things of the physical  world perceived by the senses. This belief in absolute values rooted in an  eternal world distinguishes Platonism from the philosophies of Plato�s  immediate predecessors and successors and from later philosophies  inspired by them. See also Neoplatonism.</p><p>platoon Principal subdivision of a military company, battery, or troop.  Usually commanded by a lieutenant, it consists of 25-50 soldiers orga�  nized into two or more squads led by noncommissioned officers. The term  was first used in the 17th century to refer to a small body of musketeers  who fired together in a volley alternately with another platoon. It has been  used in U.S. military manuals since 1779, and throughout the 19th cen�  tury it meant half a company. It was reintroduced into the British army  in 1913. See also military unit.</p><p>Platt, Orville Hitchcock (b. July 19, 1827, Washington, Conn.,  U.S.��d. April 21, 1905, Washington) U.S. politician. He served in the  Connecticut legislature (1861-62, 1864, 1869) and later in the U.S. Sen�  ate (1879-1905), where he sponsored legislation concerning patents and  copyrights. He was chairman of the committee on territories (1887-93),  which recommended admission of six new western states. He is remem�  bered for sponsoring the Platt Amendment (1901), which became the basis  for the withdrawal of U.S. troops from Cuba following the Spanish-  American War of 1898.</p><p>Platt Amendment (1901) Rider appended to a U.S. Army appropria�  tions bill stipulating conditions for withdrawing of U.S. troops remaining  in Cuba after the Spanish-American War. The amendment, which was  added to the Cuban constitution of 1901, affected Cuba�s rights to nego�  tiate treaties and permitted the U.S. to maintain its naval base at  Guantanamo Bay and to intervene in Cuban affairs �for the preservation  of Cuban independence.� In 1934 Pres. Franklin Roosevelt supported abro�  gation of the amendment�s provisions except for U.S. rights to the naval  base.

About 23 in. (60 cm) long, the squat-bodied platypus has a ducklike snout,  short legs, webbed feet, and a beaverlike tail. Each day it eats nearly its  own weight in crustaceans, fishes, frogs, mollusks, tadpoles, and earth�  worms; lacking teeth, it crushes its food with ridges in the bill. The female  lays one to three eggs in a nest in a long twisting passage above the  waterline. The young are weaned about four months after hatching. The  male�s heel bears a spur connected to a poison-secreting gland. Large  fishes and perhaps snakes prey on platypuses. Formerly trapped for their  dense, soft fur, they are now protected by law.</p><p>Plautus \'plo-t3s\ (b. c. 254, Sarsina, Umbria?�d. 184 bc) Roman  comic playwright. Little is known for certain about his life, but tradition  holds that he was associated with the theatre from an early age. Like other  Roman playwrights, he borrowed plots and dramatic techniques from  Greek authors, especially New Comedy playwrights such as Menander. His  plays, written in verse, were often farces marked by cases of mistaken  identity and opportunities for slapstick, and he popularized character types  such as the braggart soldier and the sly servant. Twenty-one of his  comedies�among the earliest surviving works in Latin�are extant,  including The Pot of Gold, The Captives, The Two Menaechmuses, The  Braggart Warrior, and Pseudolus. His work influenced European comedy  from the Renaissance onward, notably William Shakespeare�s Comedy of  Errors (1592-93) and Moliere�s The Miser (1669).</p><p>play See theatre</p><p>play In zoology, actions that have all the elements of purposeful behav�  iour but are performed for no apparent reason. Play has been documented  only among mammals and birds. It is most common among immature  animals, but adult animals also play. Horses, cattle, and other ungulates  run and kick up their heels even when not fleeing from predators or  defending themselves. Dogs adopt an aggressive posture to entice others  to join in mock combat. Otters are well known for their mud sliding. Male  birds may spontaneously perform their territorial songs when there is no  intruding rival.</p><p>playa VplI-9\ or pan or flat or dry lake Flat-bottomed depression  that is periodically covered by water. Playas occur in interior desert basins  and adjacent to coasts in arid and semiarid regions.

Nov. 1, 1935, Johannesburg, S.Af.) South  African golfer. Player entered the U.S. PGA circuit in 1957. He won the  British Open three times (1959, 1968, 1974), the Masters three times  (1961, 1974, 1978), the PGA twice (1962, 1972), and the U.S. Open once  (1965). Player was the third man (after Gene Sarazen and Ben Hogan) to  win the four tournaments composing the modern grand slam of golf (the  Masters, the U.S. Open, the British Open, and the PGA Championship).</p><p>player piano Piano that mechanically plays music encoded as perfo�  rations on a paper roll. An early ver�  sion, patented in 1897 by the  American engineer E.S. Votey, was a  cabinet placed in front of an ordinary  piano, with wooden �fingers� pro�  jecting over the keyboard. A paper  roll with perforations corresponding  to the notes passed over a tracker bar  to activate the release of air by pneu�  matic devices that set the fingers in  motion; the user could control tempo  and loudness by levers and pedals.</p><p>Soon this mechanism was built into  the piano itself. The later �reproduc�  ing piano� could reproduce the  nuances of tempo and dynamics in  great performances, the roll having  been produced by the performance  itself. After the 1920s the phono�  graph led to the instrument�s quick  decline. Modern versions, such as the  Yamaha Disklavier, are operated by  digital memory on a computer disk.</p><p>playing cards Small rectangular cards used for playing games and  sometimes for divination and conjuring. Modem cards are divided into  four suits: spades, hearts, diamonds, and clubs. A complete pack, or deck,  of cards includes 13 cards in each suit (10 numbered cards and 3 court  cards�king, queen, and jack, or knave); 2 extra cards, called jokers (many  times portraying a medieval jester), are often included as well. The ori�  gin of playing cards is obscure�China and India being the two most  likely sources�as is the meaning of their symbols. The earliest reference  to cards in Europe occurs in Italy in 1299. The 52-card French deck is  now standard throughout the world, but decks with fewer cards evolved  in Germany and Spain. Other suit emblems were also used (e.g., bells in  Germany, cups in Spain and Italy).

Supporters claim plea  bargaining speeds court proceedings and guarantees a conviction; oppo�  nents believe it prevents justice from being served.</p><p>plebeian \ple-'be-3n\ (Latin, plebs) Member of the general citizenry, as  opposed to the patrician class, in the ancient Roman republic. Plebeians were  originally excluded from the Senate and from all public offices except  military tribune, and they were forbidden to marry patricians. Seeking to  acquire equal rights, they carried on a campaign called Conflict of the  Orders, developing a separate political organization and seceding in pro�  test from the state at least five times. The campaign ceased when a ple�  beian dictator (appointed 287 bc) made measures passed in the plebeian  assembly binding on the whole community.</p><p>plebiscite Vple-bs-.shA Vote by the people of an entire country or dis�  trict to decide an issue. Voters are asked to accept or reject a given pro�  posal rather than choose between alternative proposals. By means of  plebiscites, intermediaries such as political parties can be bypassed.  Because plebiscites offer a way to claim a popular mandate without per�  mitting an opposition party, totalitarian regimes have used them to legiti�  mize their power.

He became head of the imperial  chancellery (1894), state secretary for Finland (1899), and minister of the  interior (1902). Concerned with upholding autocratic principles, he sup�  pressed revolutionary and liberal movements, harshly pursued Russifica�  tion policies against minority nationality groups, and backed police-  controlled labour unions.

It contains a large amount of bright  nebulous material and several hundred stars, of which six or seven can  be seen by the unaided eye and have figured prominently in the myths  and literature of many cultures. In the Northern Hemisphere, the rising  of the Pleiades near dawn in spring has from ancient times marked the  opening, and their morning setting in autumn the end, of seafaring and  farming seasons.</p><p>Pleistocene Vplls-t9-,sen\ Epoch Earlier and longer of the two epochs  that constitute the Quaternary Period. The Pleistocene began c. 1.8 mil�  lion years ago and ended c. 10,000 years ago. It was preceded by the  Pliocene Epoch of the Tertiary Period and followed by the Holocene Epoch.  At the height of the Pleistocene glacial ages, more than 30% of the land  area of the Earth was covered by glacial ice; during the interglacial stages,  probably only about 10% was covered. The animals of the Pleistocene  began to resemble those of today, and new groups of land mammals,  including humans, appeared. At the end of the epoch, mass extinctions  occurred: in North America more than 30 genera of large mammals  became extinct within a span of roughly 2,000 years. Of the many causes  that have been proposed for these extinctions, the two most likely are  changing environment with changing climate and disruption of the eco�  logical pattern by early humans.</p><p>Plekhanov \pli-'ka-nof\, Georgy (Valentinovich) (b.

In 1883 he  founded the first Russian Marxian revolutionary organization, Liberation  of Labour, which became the Russian Social-Democratic Workers' Party  (1898). In Socialism and Political Struggle (1883) and Our Differences  (1885), he described a two-phase revolutionary scheme that influenced  Russian Marxist thought. Followers in the 1890s included Vladimir Ilich  Lenin. After the party split (1903), Plekhanov joined the Mensheviks but  spent years trying to reunite the party. He supported the Allies in World  War I and opposed the Bolshevik seizure of power. After returning briefly  to Russia in 1917, he died in exile in Finland.</p><p>Plessy v.

His publishing  house, Maison Pleyel, published Haydn�s complete string quartets (1801),  and in 1802 it published the first miniature scores for study. It ceased  publishing in 1834, but the piano-manufacturing company he founded in  1807 lasted until the 1960s.

At age 27 he traveled to Alex�  andria, where he studied philosophy for 11 years. In about 242 he joined  the expedition of the Roman emperor Gordian III against Persia in order  to learn about the philosophies of the Persians and Indians. He went to  Antioch and then to Rome, where he settled at age 40, becoming the cen�  tre of an influential circle of intellectuals. His attempt to form a Platonic  republic in Campania c. 265 was halted by the emperor Galuenus. He was  the founder of the school of philosophy known as Neoplatonism; his col�  lected works, the Enneads (from Greek, enneas: �set of nine�), arranged  by his disciple Porphyry (232?-c. 305), are the first and greatest collec�  tion of Neoplatonic writings. For Plotinus, philosophy was not only a  matter of abstract speculation but also a way of life and a religion. His  works strongly influenced early Christian theology, and his philosophy  was widely studied and emulated for many centuries.</p><p>Plovdiv \'pl6v-,dif\ City (pop., 2001: 340,638), south-central Bulgaria.

Even�  tually the development of separate, underground water and sewage sys�  tems eliminated open sewage ditches. Present-day water pipes are usually  made of steel, copper, brass, plastic, or other nontoxic material. A build�  ing�s waste-disposal system has two parts: the drainage system and the  venting system. The drainage portion comprises pipes leading from vari�  ous fixture drains to the central main, which is connected to the sewage  system. The venting system consists of pipes leading from an air inlet  (usually on the roof) to various points within the drainage system; by pro�  viding the circulation of air within the system, it protects the trap seals  of fixtures from siphonage and back pressure. See also sewage system,  water pollution, water-supply system. See illustration opposite.</p><p>Plunket, Saint Oliver (b. 1629, Loughcrew, County Meath, Ire.�d.  July 1, 1681, London, Eng.; canonized 1975; feast day July 11) Irish prel�  ate, the last man to suffer martyrdom for the Catholic faith in England.  He was ordained in Rome, where he taught theology and represented the  Irish bishops at the Holy See. In 1669 he was appointed archbishop of  Armagh and primate of Ireland, and he worked to restore the disorga�  nized church in Ireland. Renewed persecution forced him into hiding in  1673. In the anti-Catholic hysteria caused by the Titus Oates plot (1678),  he was betrayed and imprisoned in Dublin in 1679. After a farcical trial  in London, he was convicted of treason and was hanged, drawn, and  quartered. His head, originally sent to Rome, is preserved at Drogheda,  and his body is at Downside Abbey, near Bath.</p><p>pluralism In political science, the view that in liberal democracies  power is (or should be) dispersed among a variety of economic and ideo�  logical pressure groups and is not (or should not be) held by a single elite  or group of elites. Pluralism assumes that diversity is beneficial to soci�  ety and that the disparate functional or cultural groups of which society  is composed�including religious groups, trade unions, professional orga�  nizations, and ethnic minorities�should be autonomous. Pluralism was  stressed most vigorously during the early 20th century by a group of  English writers that included Frederic W. Maitland and Harold J. Laski; it  was defended in the later 20th century by the American scholars Robert  Dahl and David B. Truman.</p><p>The basic components of a plumbing fixture include the water-supply pipes, a valve  or faucet for controlling the flow of water, and a drainpipe to carry wastewater  away. An air chamber may be added to the supply line to cushion the effects of  water hammer. A trap in the drain line leaves a plug of water in the pipe to prevent  unwanted sewer gases from entering the room via the drain.</p><p>� MERRIAM-WEBSTER INC.</p><p>pluralism In metaphysics, the doctrine opposed to monism. Whereas  monists such as Parmenides, Benedict de Spinoza, and G.W.F. Hegel main�  tain that reality consists of only one ultimate substance, pluralists assert  that reality consists of manifold entities of many different types and that  the diversity of things is more striking and important than their unity. In  A Pluralistic Universe (1909), William James held that it is characteristic  of empirically minded thinkers to note the changeability of things, the  multiplicity of their being and their relations with one another, and the  unfinished character of the world.</p><p>plurality system Electoral process in which the candidate who polls  more votes than any other candidate is elected. It is distinguished from the  majority system, in which, to win, a candidate must receive more votes than  all other candidates combined. It is the most common method of selecting  candidates for public office. Its chief advantage is that it avoids the need for  runoffs to produce a winner. Its chief disadvantage is that it may result in a  winner who has received a minority of the votes cast. It operates best in a  two-party system, where the small vote for any third party will rarely result  in an outcome seriously at odds with the voters� will.</p><p>Plutarch Vplii-.tarkV Greek Plutarchos Latin Plutarchus (b. ad 46,</p><p>Chaeronea, Boeotia�d. after 119) Greek biographer and author. The son of  a biographer and philosopher, Plutarch studied in Athens, taught in Rome,  traveled widely, and made many important friends before returning to his  native town in Boeotia. His literary output was immense, but his popularity  rests primarily on his Parallel Lives, a series of pairs of biographies of  famous Greeks and Romans. Displaying impressive learning and research,  the Lives exhibit noble deeds and characters and provide model patterns of  behaviour. The Moralia, or Ethica, contains his surviving writings on ethi�  cal, religious, physical, political, and literary topics. His works profoundly  influenced the evolution of the essay, biography, and historical writing in  16th-19th-century Europe, especially through translations such as Sir Tho�  mas North�s Lives of the Noble Grecians and Romanes (1579), William  Shakespeare�s source for his Roman history plays.</p><p>Pluto Ninth planet from the Sun.

Its axis is tipped 120�, so it rotates nearly on its side and �back�  ward� (see retrograde motion) once every 6.39 days, locked synchronously  with the orbit of its largest moon, Charon, discovered in 1978. Two addi�  tional, small moons were discovered in 2005. Pluto has a diameter of about  1,455 mi (2,340 km), roughly two-thirds that of the Moon, and has less than  1% of Earth�s mass and only about 6% of its surface gravity. Its estimated  average surface temperature is near -390 �F (-235 �C). Its thin atmosphere  contains nitrogen, methane, and perhaps other heavier gases. Pluto is  thought to be made of frozen gases with a significant fraction of rocky  material. Its size, composition, and orbital location in the Kuiper belt have  sparked debate over its classification as a major planet.</p><p>plutonium Radioactive (see radioactivity) metallic chemical element,  chemical symbol Pu, atomic number 94. A member of the actinide series of  transition elements, it is the most important transuranium element because of  its use in certain types of nuclear reactors (see nuclear power) and in nuclear  weapons. It is found in nature only in traces produced by natural neutron  irradiation in uranium ores. It is produced artificially by neutron irradiation  of uranium-238. Plutonium is a silvery metal that tarnishes in air; it is warm  because of energy released in alpha decay. Its isotopes, all radioactive, are  highly toxic radiological poisons (see radiation injury) because they give off  alpha particles and are specifically absorbed by bone marrow.</p><p>Plymouth City (pop., 1999 est.: 255,800) in Devon, southwestern  England. Located on Plymouth Sound southwest of London, the city was  named Sudstone in Domesday Book (1086); its harbour is called Sutton  Harbour. It was the port from which the English fleet sailed against the  Spanish Armada in 1588. In 1690 its dockyard was built on the western  bank of the River Tamar. During World War II Plymouth suffered bomb  damage from air raids. The rebuilt city has some of the finest commer�  cial, shopping, and civic centres in Britain and new bridges over the Riv�  ers Plym and Tamar.</p><p>Plymouth City (pop., 2000: 51,701), southeastern Massachusetts, U.S.  Located on Plymouth Bay, it was the site of the first permanent European  settlement in New England, the Colony of New Plymouth, founded by  the Pilgrims in 1620 and governed under the Mayflower Compact until  1691, when it became part of Massachusetts Bay Colony. Its seaside loca�  tion and historic associations make Plymouth an outstanding summer  resort. A tourist-based economy is supplemented by light industry, fish�  ing, and cranberry growing. Historical attractions include Plimoth Plan�  tation (a recreation of the original Pilgrim village) and many restored early  colonial houses.</p><p>Plymouth Company (1606-09) Commercial trading company char�  tered by the English crown to colonize the eastern coast of North America  in present-day New England. Also called the Virginia Colony of Plymouth,  its shareholders were merchants of Plymouth, Bristol, and Exeter. Its twin  company was the more successful London Company. The Plymouth Com�  pany established a colony on the coast of Maine in 1607 but soon aban�  doned it. Inactive after 1609, it was reorganized under a new charter in  1620 as the Council for New England. See also chartered company.</p><p>plywood Manufactured panel made up of three or more thin plies (lay�  ers) of wood. Each ply is laid down with its grain running perpendicular  to the one before it. Like other glued-wood products, plywood provides  a strong, inexpensive alternative to solid wood. It is widely used both in  cabinetmaking (for chests, dressers, wardrobes, and tables) and in house  construction (for walls, ceilings, subfloors, doors, and in forms for cast�  ing concrete).</p><p>PMS See premenstrual syndrome</p><p>pneumatic device \nu-'ma-tik\ Any of various tools and instruments  that generate and use compressed air. Examples include rock drills, pave�  ment breakers, riveters, forging presses, paint sprayers, blast cleaners, and  atomizers. Compressed-air power is flexible, economical, and safe. In  general, pneumatic systems have relatively few moving parts, contribut�  ing to high reliability and low maintenance costs.</p><p>pneumatic structure Membrane structure that is stabilized by the pres�  sure of compressed air. Air-supported structures are supported by inter�  nal air pressure. A network of cables stiffens the fabric, and the assembly  is supported by a rigid ring at the edge. The air pressure within this bubble  is increased slightly above normal atmospheric pressure and maintained  by compressors or fans. Air locks are required at entrances to prevent loss</p><p>of internal air pressure. Air-supported membranes were first devised by  Walter Bird in the late 1940s and were soon put to use as covers for  swimming pools, temporary warehouses, and exhibition buildings. Air-  inflated structures are supported by pressurized air within inflated build�  ing elements that are shaped to carry loads in a traditional manner.  Pneumatic structures are perhaps the most cost-effective type of building  for very long spans.</p><p>pneumococcus V.nu-mo-'ka-kosX Spheroidal bacterium ( Streptococcus  pneumoniae ) that causes human diseases including pneumonia, sinusitis,  ear infection, and meningitis. Usually occurring in the upper respiratory  tract, this gram-positive (see gram stain) coccus is often found in a chain  configuration and surrounded by a polysaccharide capsule. Pneumococci  are separated into types depending on the specific capsular polysaccha�  ride formed. Their disease-causing ability resides in the capsule, which  delays or prevents their destruction by cells in the bloodstream that nor�  mally engulf foreign material.</p><p>pneumoconiosis X.nu-mo-.ko-ne-'o-sssV Any lung disease caused by  inhalation of organic or inorganic dusts or chemical irritants, usually over  time. Some dusts (e.g., silica minerals, asbestos) produce grave reactions in  small quantities. Dust collects in the pulmonary alveoli, causing inflam�  mation that scars lung tissue, reducing its elasticity. Chest tightness and  shortness of breath may progress to chronic bronchitis and emphysema.  Cigarette smoking worsens many types. The most common cause of  severe disease is silica (see silicosis). Asbestos (see asbestosis), beryllium,  and aluminum dusts can cause worse disease, often on brief exposure.  Organic causes include mold spores (see allergy) and textile fibres. Chemi�  cal irritants such as ammonia, acid, and sulfur dioxide are soon absorbed  by the lung lining; their irritant effect can cause pulmonary edema, and  they can lead to chronic bronchitis.</p><p>pneumonia \nu-'mon-y9\ Inflammation and solidification of lung tissue  caused by infection, foreign particle inhalation, or irradiation but usually  by bacteria. Mycoplasma pneumoniae is the most common cause in healthy  individuals. The bronchi and alveoli may be inflamed. Coughing becomes  severe and may bring up flecks of blood. It can be serious but is rarely fatal.  Streptococcus pneumoniae is more common and generally more severe but  usually affects only those with low resistance, especially in hospitals. A  highly lethal form caused by Klebsiella pneumoniae is almost always con�  fined to hospitalized patients with low immunity. Other bacterial pneumo�  nias include Pneumocystis carinii pneumonia (rare except in AIDS) and  Legionnaire disease. Most respond to antibiotic treatment. ViRUses set the  stage for bacterial pneumonia by weakening the individual�s immune sys�  tem more often than they cause pneumonia directly. Fungal pneumonia  usually occurs in hospitalized persons with low resistance, but contami�  nated dusts can cause it in healthy individuals. It can develop rapidly and  may be fatal. X-ray treatment (see radiation therapy) of structures in the  chest may cause temporary lung inflammation.</p><p>pneumothorax Condition in which air accumulates in the pleural sac,  causing it to expand and thus compress the underlying lung, which may  then collapse. (The pleural sac is a cavity formed by the two pleural  membranes that line the thoracic cavity and cover the lungs.) Traumatic  pneumothorax is the accumulation of air caused by penetrating wounds  (knife stabbing, gunshot) or other injuries to the chest wall, after which  air is sucked through the opening and into the pleural sac. Spontaneous  pneumothorax is the passage of air into the pleural sac from an abnormal  connection created between the pleura and the bronchial system as a result  of tuberculosis or some other lung disease. The symptoms of spontane�  ous pneumothorax are a sharp pain in one side of the chest and shortness  of breath.</p><p>Po Chu-i See Bo Juyi  Po Hai See Bo Hai</p><p>Po River ancient Padus River, northern Italy. The country�s longest  river, it is about 405 mi (652 km) long. It rises in the Cottian Alps on the  western frontier and flows northeast to Turin, then east across Piedmont  and Lombardy into the Adriatic Sea. Its delta is one of the most complex  of any European river, with at least 14 mouths. It is navigable from its  mouth to Pavia. Industrial cities in its valley include Milan, Padua, and  Verona. It has suffered devastating autumn floods, including those in 589,  1438, 1951, and 1966.</p><p>Pobedonostsev Vpo-byi-do-'nost-syiA, Konstantin (Petrovich)</p><p>(b. May 21, 1827, Moscow, Russia�d.

Serving for six months or a  year, the podesta summoned councils, led the communal army, and admin�  istered civil and criminal jurisdiction.</p><p>Podgorica Vpod-.gor-et-sa \ formerly (1946-92) Titograd City (pop.,  1999 est.: 130,875), capital of Montenegro, southern Serbia and Montene�  gro. As a feudal state capital in the early Middle Ages, it was known as  Ribnica; it was called Podgorica from 1326. It fell to the Turks in 1474 but  was restored to Montenegro in 1878. It was occupied in 1916 by Austria, in  1941 by Italy, and in 1943 by Germany. In 1946 it became Titograd in  honour of Marshal Tito, but its former name was restored in 1992 after the  collapse of communism. It is the site of a university (founded 1974).</p><p>Podgorny \p6d-'g6r-ne\, Nikolay (Viktorovich) (b. Feb. 18,1903,  Karlovka, Ukraine, Russian Empire�d. Jan. 12, 1983, Moscow, Russia,  U.S.S.R.) Soviet politician. He worked in engineering jobs in the sugar  industry, then was appointed deputy commissar of the Soviet food�  processing industry in 1940. He rose through the Communist Party hier�  archy to become chair of the Ukraine party committee (1957-63), a full  member of the Politburo (1960), and head of the party�s Central Com�  mittee (1963-65).

U.S. poet, critic, and short-story writer. Poe was  raised by foster parents in Richmond, Va., following his mother�s death  in 1811. He briefly attended the University of Virginia and then returned  to Boston, where in 1827 he published a pamphlet of youthful, Byronic  poems. By 1835 he was in Richmond as editor of the Southern Literary  Messenger, the first of several periodicals he was to edit or write for. There  he married a 13-year-old cousin, who died in 1847. At various times he  lived in Baltimore, New York, and Philadelphia. Alcohol, the bane of his  irregular and eccentric life, caused his death at age 40. His works are  famous for his cultivation of mystery and the macabre. Among his tales  are �The Fall of the House of Usher,� �The Masque of the Red Death,�  �The Black Cat,� �The Tell-Tale Heart,� and �The Pit and the Pendulum.�  �The Murders in the Rue Morgue� and �The Purloined Letter� initiated  the modern detective story. His poems (less highly regarded now than for�  merly) are musical and sensuous, as in �The Bells,� a showcase of sound  effects; they include touching lyrics inspired by women (e.g., �Annabel  Lee�) and the uncanny (e.g., �The Raven�).</p><p>poet laureate Title first granted in England for poetic excellence.  Begun in 1616, the office was formally established in 1668 and has been  continuous since then. Its holder, a salaried member of the British royal  household, was formerly expected to compose poems for court or national  occasions, but since the appointment of William Wordsworth in 1843 the  office has been a reward for eminence in poetry and has carried no spe�  cific duties. In 1985 the U.S. government created the title of poet laure�  ate, to be held by the consultant in poetry to the Library of Congress.</p><p>poetry Writing that formulates a concentrated imaginative awareness of  experience in language chosen and arranged to create a specific emotional  response through its meaning, sound, and rhythm. It may be distinguished  from prose by its compression, frequent use of conventions of metre and  rhyme, use of the line as a formal unit, heightened vocabulary, and free�  dom of syntax. Its emotional content is expressed through a variety of  techniques, from direct description to symbolism, including the use of  metaphor and simile. See also prose poem; prosody.</p><p>Poetry U.S. poetry magazine founded in Chicago in 1912 by Harriet  Monroe, who became its longtime editor. It became the principal organ  for modern poetry of the English-speaking world and survived through  World War II. Because its inception coincided with the Chicago literary  renaissance, it is often associated with the raw, local-colour poetry of Carl  Sandburg, Edgar Lee AAasters, Vachel Lindsay, and Sherwood Anderson, but  it also championed new formalistic movements, including Imagism. Ezra  Pound was its European correspondent; among the authors it published  were T.S. Eliot, Wallace Stevens, Marianne Moore, D.H.

While working as a copyist of manuscripts,  Poggio invented the humanist script, which later became the prototype  for Roman fonts in printing. He traveled to various monasteries in Europe,  uncovering lost, forgotten, or neglected classical Latin manuscripts,  including works by Cicero and Lucretius. He also translated works by  Lucian, Xenophon, and others into Latin. His own writings include moral  dialogues and Facetiae (1438-52), a collection of humorous tales con�  taining satires of his contemporaries.</p><p>pogrom \p3-'gram\ Russian "devastation" or "riot" Mob attack,  condoned by authorities, against persons and property of a religious,  racial, or national minority. The term is usually applied to attacks on Jews  in Russia in the late 19th and early 20th centuries. After the assassination  of Tsar Alexander II (1881), false rumours associating Jews with the mur�  der aroused Russian mobs in more than 200 cities and towns to attack  Jews and destroy their property. Mob attacks diminished in the 1890s, but  they again became common in 1903-06. Although the government did  not organize pogroms, its anti-Semitic policy (1881-1917) and reluctance  to stop the attacks led many anti-Semites to believe that their violence  was legitimate. Pogroms also occurred in Poland and in Germany during  Adolf Hitler�s regime.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>pogy &#x25BA; poison ivy I 1517</p><p>pogy See menhaden</p><p>Poincare \pwa n -ka-'ra\, (Jules-) Henri (b.

In  1908 he revived the Empire style, popular in France during the reign of  Napoleon I. Seeking to restore naturalness to female garb, he was prin�  cipally responsible for the decline of the corset. He is best known for the  hobble skirt, to which he later added draped and belted knee-length tunics.  Fringed and tasseled capes, multicoloured feathers, and fox stoles  imparted a theatrical look to his designs. His flowing Greek costumes  were extremely popular in the prewar era, but his popularity faded in the  1920s and he died in poverty.</p><p>poison Any substance (natural or synthetic) that, at a certain dosage,  damages living tissues and injures or kills. Poisons spontaneously pro�  duced by living organisms are often called toxins, venoms if produced by  animals. Poisons may be ingested, inhaled, injected, or absorbed through  the skin. They do not always have an all-or-none effect; degrees of poi�  soning may occur, and at a given dose some substances are far more toxic  than others (e.g., a pinch of potassium cyanide can kill, whereas a single  dose of ordinary table salt must be massive to kill). Poisoning may be  acute (a single dose does significant damage) or chronic (repeated or con�  tinuous doses produce an eventual effect, as with chemical carcinogens).  The effects produced by poisons may be local (hives, blisters, inflamma�  tion) or systemic (hemorrhage, convulsions, vomiting, diarrhea, clouding  of the senses, paralysis, respiratory or cardiac arrest). Agricultural pesti�  cides are often poisonous to humans. Some industrial chemicals can be  very toxic or carcinogenic. Most therapeutic drugs and health-care prod�  ucts can be poisons if taken inappropriately or in excess. Most forms of  radiation can be toxic (see radiation injury).

It is now common in the U.S. as well as in Europe. A tall  biennial, this plant has green stems spotted with red or purple, large com�  pound leaves, and white flowers. Though the poison is concentrated in  the seeds, the entire plant is dangerous to livestock when fresh. Despite  their common name, poison hemlocks are not conifers (see hemlock).  Water hemlocks (Cicuta species) are similar and also dangerous.</p><p>poison ivy Either of two North American species of white-fruited  woody vines or shrubs of the sumac, or cashew, family. The species found</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1518 I poison oak &#x25BA; Poland</p><p>in eastern North America ( Toxico�  dendron radicans) is abundant; a  western species, known as poison  oak, is less common. Both species  are sometimes classified as genus  Rhus. A key identifier is leaves with  three mitten-shaped leaflets. Contact  with urushiol, an oil produced by the  plant, can cause severe inflammation  and blistering of human skin. Urush�  iol may be carried from the plant on  clothing, shoes, tools, or soil; by ani�  mals; or by smoke from burning  plants. Because urushiol is nonvola�  tile, a reaction may result from wear�  ing clothing a year or more after its  contact with the plant.</p><p>poison oak Species of poison ivy ( Toxicodendron diversilobum) native  to western North America and classified in the sumac (or cashew) family.  Like many other lobe-leafed plants commonly called oak, poison oak is  not an OAK tree (genus Quercus).</p><p>poison sumac also called poison elder Attractive, narrow shrub or  small tree ( Rhus vernix or Toxicodendron vernix ) of the sumac, or cashew,  family. It is native to swampy acidic soils of eastern North America.  Unlike the upright reddish, fuzzy fruit clusters of other sumacs, whitish  waxy berries droop loosely from its stalks. The clear sap, which black�  ens on exposure to air, is extremely irritating to the skin for many people.</p><p>Poitier \'pwa-te-,a\, Sidney (b. Feb. 20, 1927?, Miami, Fla., U.S.) U.S.  actor. He was raised in The Bahamas, then studied and acted with the  American Negro Theatre in New York City. He made his film debut in  No Way Out (1950) and gave notable performances in Blackboard Jungle  (1955) and The Defiant Ones (1958). He won acclaim on Broadway for  his role in A Raisin in the Sun (1959). He became the first African Ameri�  can actor to win an Academy Award, for his role in Lilies of the Field  (1963). He used his critical and commercial success to push for integrated  film crews. He went on to star in notable films such as In the Heat of the  Night (1967), To Sir with Love (1967), and Guess Who�s Coming to Din�  ner (1967). He also directed several films, including Buck and the  Preacher (1972), Let�s Do It Again (1975), and Stir Crazy (1980). In 1997  he was appointed The Bahamian ambassador to Japan.</p><p>Poitiers, Battle of (732) See Battle of Tours/Poitiers</p><p>Poitiers \pwa-'tya\, Battle of (September 19, 1356) Catastrophic  defeat of the French king John II in the Hundred Years' War between France  and England. English troops under Edward the Black Prince were under  pursuit from the probably superior French forces. South of Poitiers the  English secured themselves in thickets and marshes, where the French  knights became bogged down and made easy targets for the English  archers. John II was taken prisoner and for his freedom had to consent to  the disadvantageous Treaties of Bretigny and Calais.</p><p>Poitou \pwa-'tu\ Historical region, western central France. It was  bounded by Brittany, Anjou, Touraine, Marche, and the Atlantic Ocean. It  was inhabited by the ancient Gallic tribe of Pictones and became part of  Roman Aquitania. A meeting place of northern and southern cultures, its  golden age (11th�12th century) was characterized by great Romanesque  art and architecture. The counts of Poitiers were succeeded by the  Angevin kings of England, but by 1375 the French had won the region  back. It was a province of France until the French Revolution, when it was  divided into three departments. It is predominantly a rural area; regional  specialties include seafood and white wine.</p><p>poker Any of several card games in which a player bets that the value  of his or her hand is greater than that of the hands held by others. Each  subsequent player must either equal or raise the bet or drop out. The pot  is eventually won by either the player showing the best hand when it  comes to a showdown or the only player left when everyone else has  dropped out, or �folded.� In this case the winner need not show his hand  and could conceivably have won the pot with a lower hand than any other  at the table. It is for this reason that poker is described as a game of bluff.  Three principal forms of the game have developed: straight poker, in  which all cards of the standard five-card hand are dealt facedown; stud  poker, in which some but not all of a player�s cards are dealt faceup; and</p><p>Poison ivy (Toxicodendron radicans)</p><p>WALTER CHANDOHA</p><p>community-card poker, in which some cards are exposed and used by all  the players to form their best hand. In draw poker, the main variant of  straight poker, cards may be discarded and additional cards drawn. The  traditional ranking of hands is (1) straight flush (five cards of the same  suit in sequence, the highest sequence�ace, king, queen, jack, ten�being  called a royal flush), (2) four of a kind, (3) full house (three of a kind,  plus a pair), (4) flush (five of a single suit), (5) straight (five in sequence),  (6) three of a kind, (7) two pair, (8) one pair.</p><p>pokeweed also called pokeberry or poke Strong-smelling shrub�  like plant ( Phytolacca americana) with a poisonous root resembling the  shape of horseradish, native to wet or sandy areas of eastern North  America. It has white flowers, reddish black berries, and dark green leaves  that often are red-veined or borne on red leafstalks. The berries contain a  red dye used to colour wine, candies, cloth, and paper. Like the roots, the  red or purplish mature stalks are poisonous. Very young green shoots (up  to about 6 in. [15 cm]), however, are edible.</p><p>Pokrovsky Cathedral See Saint Basil the Blessed</p><p>Pol Pot orig. Saloth Sar (b. May 19, 1925/28, Kompong Thom prov�  ince, Cambodia�d. April 15, 1998, near Anlong Veng) Prime minister of  Cambodia. He joined the anti-French resistance under Ho Chi Minh in the  1940s and became a member of the Cambodian Communist Party in 1946.  After studying radio technology in Paris, he returned to Cambodia in 1953  and taught French until he fell under police suspicion in 1963. For the next  12 years he built up the Communist Party. U.S. anticommunist activity in  Cambodia in the early 1970s, including helping to depose Norodom Siha�  nouk and a bombing campaign in the countryside, drove many to join him.  In 1975 his Khmer Rouge forces captured Phnom Penh, which he ordered  entirely evacuated. Even the sick were wheeled out in hospital beds, and in  the first weeks it is estimated that tens of thousands died. The ruthlessness  with which he pursued his intention to return to �year zero� and create an  ethnically pure, agrarian, communist state resulted in the deaths of one to  two million people. Overthrown by the Vietnamese in 1979, he led an anti-  Vietnamese guerrilla war until he was repudiated by the Khmer Rouge and  sentenced to life imprisonment (1997); he died the next year.</p><p>Poland officially Republic of Poland Country, central Europe.

The Vistula and Oder, the principal river  systems, both drain into the Baltic Sea. Industries include mining, manu�  facturing, and public utilities. Poland is a republic with two legislative  houses; its chief of state is the president, and its head of government is  the prime minister. Established as a kingdom in 922 under Mieszko I,  Poland was united with Lithuania in 1386 under the Jagiellon dynasty  (1386-1572) to become the dominant power in east-central Europe,  enjoying a prosperous golden age. In 1466 it wrested western and east�  ern Prussia from the Teutonic Order, and its lands eventually stretched to  the Black Sea. Wars with Sweden (see First Northern War; Second  Northern War) and Russia beginning in the late 17th century led to the  loss of considerable territory. In 1697 the electors of Saxony became kings  of Poland, virtually ending Polish independence. In the late 18th century  Poland was divided between Prussia, Russia, and Austria (see partitions  of Poland) and ceased to exist. After 1815 the former Polish lands came  under Russian domination, and from 1863 Poland was a Russian prov�  ince, subjected to intensive Russification. After World War I an indepen�  dent Poland was established by the Allies. The invasion of Poland in 1939  by the U.S.S.R. and Germany precipitated World War II, during which  the Nazis sought to purge Poland�s culture and its large Jewish popula�  tion in the Holocaust. Reoccupied by Soviet forces in 1945, Poland was  controlled by a Soviet-dominated government from 1947. In the 1980s  the Solidarity labour movement led by Lech Walesa achieved major politi�  cal reforms, and free elections were held in 1989. An economic austerity  program instituted in 1990 sped the transition to a market economy.  Poland became a member of NATO in 1999 and the European Union in</p><empty-line/><p>Poland, partitions of (1772, 1793, 1795) Territorial divisions of  Poland by Russia, Prussia, and Austria that progressively reduced its ter�  ritory until it ceased to exist as a state. In the First Partition (1772), a  Poland weakened by civil war and Russian intervention agreed to a treaty  signed by Russia, Prussia, and Austria that deprived it of half its popu�  lation and almost one-third of its land area. In the Second Partition (1793),  Poland was forced to cede additional lands to Prussia and Russia. To quell  a nationalist uprising led by Tadeusz Kosciuszko, Russia and Prussia  invaded Poland and divided the remnants of the state among themselves  and Austria in the Third Partition (1795). Only with the establishment of  the Polish Republic in 1918 were the results of the partitions reversed.</p><p>Polanski \p3-'lan-ske\, Roman (b. Aug. 18, 1933, Paris, France)  Polish-French film director. He grew up in Poland and survived a trau�  matic wartime childhood under the Nazis. His first feature film, Knife in  the Water (1962), brought him international fame. He left Poland that year  for Britain, where he made Repulsion (1965), and later the U.S., where his  Rosemary�s Baby (1968) was highly successful. In 1969 his new wife, the  actress Sharon Tate, was murdered by followers of Charles Manson. He  directed a graphic adaptation of Macbeth (1971) and the acclaimed film  noir Chinatown (1974). In 1977 Polanski was arrested and eventually  pleaded guilty to a charge of statutory rape. He subsequently jumped bail  and fled to France, where he remained active in both the theatre and  motion pictures. His subsequent films include Tess (1979), Frantic (1988),  Bitter Moon (1992), Death and the Maiden (1994), and The Pianist  (2002), which won the Gold Palm for best film at the Cannes International  Film Festival and earned a best director Academy Award for Polanski.</p><p>polar bear White semiaquatic bear ( Ursus maritimus) found through�  out Arctic regions, generally on drift�  ing oceanic ice floes. A swift, wide-  ranging traveler and a good  swimmer, it stalks and captures its  prey. It primarily eats seal but also  fish, seaweed, grass, birds, and cari�  bou. The male weighs 900-1,600 lbs  (410-720 kg) and is about 5.3 ft (1.6  m) tall at the shoulder and 7-8 ft  (2.2-2.5 m) long. It has a short tail.</p><p>The hairy soles of its broad feet pro�  tect it from the cold and help it move  across the ice.

Scientific evidence indicates that the magnetic  poles have slowly and erratically wandered across the surface of the Earth.  Pole locations calculated from measurements on rocks younger than about</p><p>20 million years do not depart from the present pole locations by very  much, but successively greater �virtual pole� distances are revealed for  rocks older than 30 million years, indicating that substantial deviations  occurred. Calculations of polar wandering formed one of the first impor�  tant pieces of evidence for continental drift.</p><p>Polaris \p3-'lar-3s\ or North Star Earth�s present northern polestar  (the star visible from the Northern Hemisphere toward which Earth�s axis  points), at the end of the �handle� of the Little Dipper in the constella�  tion Ursa Minor. Polaris is actually a triple star, composed of a binary star  and a Cepheid variable. Precession of Earth�s axis made the star Thuban, in  the constellation Draco, the North Star in ancient Egyptian times; it will  cause the North Pole to point toward Vega, in the constellation Lyra,  12,000 years from now.</p><p>polarization Property of certain types of electromagnetic radiation in  which the direction and magnitude of the vibrating electric field are related  in a specified way. The electric vector representing the magnitude and  direction of the electric field in a wave of light is perpendicular to the  direction in which the wave is moving. Unpolarized light consists of  waves moving in the same direction with their electric vectors pointing  in random orientations about the axis of propagation. Plane-polarized light  consists only of waves that vibrate in one direction. In circular polariza�  tion the electric vector rotates about the propagation direction. Light may  be polarized by reflection or by passing it through polarizing filters, such  as certain crystals, that transmit vibrations in one plane but not in others.  Polarized light has useful applications in crystallography, liquid-crystal  displays, optical filters, and the identification of optically active chemi�  cal compounds.</p><p>Polaroid Corp. Major U.S. manufacturer of photographic equipment  and supplies. The company was established as Land-Wheelwright Labo�  ratories in 1932 by Edwin Land and George Wheelwright to produce  Land�s first invention, an inexpensive plastic-sheet light polarizer (see  polarization). By 1936 Land was using polarized material in sunglasses  and other optical devices, and in 1937 the company was incorporated  under the Polaroid name. After World War II Land invented the first  instant camera, marketed in 1947 as the Polaroid Land camera, which  delivered a finished sepia-toned print 60 seconds after exposure. The com�  pany introduced colour film for its Polaroid cameras in the 1960s and  instant motion pictures in 1977. Other Polaroid products include film,  digital cameras, and identification systems.</p><p>Pole, Reginald (b. March 3, 1500, Stourton Castle, Staffordshire,  Eng.�d. Nov. 17, 1558, London) English Catholic prelate. A cousin of  Henry VII, Pole was sent by Henry VIII to study in Italy (1521-27) and  given minor offices in the church. Critical of Henry�s antipapal policies,  he wrote In Defense of Ecclesiastical Unity (1536) to defend the pope�s  spiritual authority. As cardinal, he was sent by Pope Paul III on missions  to persuade Catholic monarchs to depose Henry. These efforts angered  Henry, who executed Pole�s brother, Lord Montague (1538), and his  mother, Margaret, countess of Salisbury (1541). Pole was named papal  governor of the Patrimony of St. Peter and later was presiding legate at  the Council of Trent. When the Catholic Mary Tudor became queen as  Mary I in 1553, he was appointed legate for England; there he instituted  church reforms and was a strong influence on the queen. He was appointed  archbishop of Canterbury (1556), but a conflict between the papacy and  England�s ally Spain caused the pope to cancel Pole�s authority and  declare him a heretic. Demoralized, he died 12 hours after the death of  Queen Mary.</p><p>pole construction Method of building that dates back to the Stone  Age. Excavations in Europe show rings of stones that may have braced  huts made of wooden poles or weighted down the walls of tents made of  animal skins supported by central poles. Two types of Native American  pole structures were the wigwam and longhouse. Pole-and-thatch dwell�  ings are common in the Caribbean, Mesoamerica, and the Pacific Islands;  bamboo-pole dwellings constructed on piles are found in many wet areas  of Asia. A southern African method utilizes a ring of poles that is inserted  into the ground, brought together in a crest, and expertly thatched. Today,  pole construction employs a vertical structure of pressure-treated wood  poles firmly embedded in the ground as a pier foundation.

See also ferret.</p><p>European polecat (Mustela putorius)</p><p>RUSS KINNE-PHOTO RESEARCHERS</p><p>police Body of agents organized to maintain civil order and public safety,  enforce the law, and investigate crime. Characteristics common to most  police forces include a quasi-military organization, a uniformed patrol and  traffic-control force, plainclothes divisions for criminal investigations, and  a set of enforcement priorities that reflects the community�s way of life.  Administration may be centralized at the national level downward, or  decentralized, with local police forces largely autonomous. Recruits usu�  ally receive specialized training and take an exam. The modem metro�  politan police force began with Sir Robert Peel in Britain c. 1829. Secret  police are often separate, clandestine organizations established by national  governments to maintain political and social orthodoxy, which typically  operate with little or no restraint.</p><p>police power Power of a government to exercise reasonable control  over people and property within its jurisdiction in the interest of general  security, health, safety, morals, and welfare. It is generally regarded as  one of the powers reserved to the states under the U.S. Constitution. In  considering cases involving the exercise of police power, the courts have  applied a doctrine called �balance of interests� to determine when the  public�s right to health and well-being outweighs private or individual  concerns. Of equal concern is that due process of law be observed.</p><p>poliomyelitis N.po-le-o-.ml-a-'lI-tosV or polio or infantile paraly�  sis Acute infectious viral disease that can cause flaccid paralysis of  muscles. Severe epidemics killed or paralyzed many people, mostly chil�  dren and young adults, until the 1960s, when Jonas Salk�s injectable killed  vaccine and Albert B. Sabin�s oral attenuated live vaccine controlled polio  in the developed world. Flulike symptoms with diarrhea may progress to  back and limb pain, muscle tenderness, and stiff neck. Destruction of spi�  nal cord motor cells causes paralysis, ranging from transient weakness to  complete, permanent paralysis, in fewer than 20% of patients. Patients  may lose the ability to use their limbs, to breathe, or to swallow and speak.  They may need physical medicine and rehabilitation, mechanical breathing  assistance, or tracheal suction to remove secretions. A �postpolio syn�  drome� occurs decades later in some cases, with weakness of muscles  that had recovered.</p><p>polis Vpa-l9s\ In ancient Greece, an independent city and its surround�  ing region under a unified government. A polis might originate from the  natural divisions of mountains and sea and from local tribal and cult divi�  sions. Usually the town was walled and contained a citadel on raised  ground (acropolis) and a marketplace (agora). Government was centred  in the town; usually there was an assembly of citizens, a council, and  magistrates. Ideally, all citizens participated in the government and in the  cults, as well as in defense and economy. Women, minors, metics, and</p><p>slaves were not citizens. Hellenism spread many of the institutions into  the Middle East. See also Athens; city-state; Sparta; Thebes.</p><p>Polisario N.po-li-'sa-re-oX officially Popular Front for the Libera�  tion of Saguia el Hamra and Rio de Oro Sahrawi political and  military group. Initially an insurgent against Spanish control of Western  Sahara, it turned to agitation against Morocco and Mauritania when the  Spanish withdrew in 1976 and those two countries partitioned the coun�  try. Mauritania made peace with the group in 1979, whereupon Morocco  annexed the whole territory. Polisario continued its resistance, mostly  from bases in Algeria. In 1991 it agreed to a ceasefire and a referendum,  which has been repeatedly postponed by Morocco, to determine the state�s  fate. See also Saharan Arab Democratic Republic.</p><p>Polish Corridor Strip of land that gave Poland access to the Baltic  Sea. Transferred to the newly constituted state of Poland as part of the  Treaty of Versailles (1919), the corridor, 20 to 70 mi (30 to 110 km) wide,  separated eastern Prussia from the main part of Germany. The Germans  resented the transfer, though the region had been historically Polish before  the partitions of Poland and was inhabited by a Polish majority. When  Poland refused to accede to Adolf Hitler�s demands for extraterritorial  highways across the corridor and cession of the free port city of Danzig  (Gdansk), Germany seized the pretext to invade Poland (1939), beginning  World War II.</p><p>Polish language West Slavic language of Poland, spoken by more than  41 million people, including 2-3 million in North America and perhaps  1.5 million in the former Soviet Union. The earliest continuous text in  Polish dates from the 14th century. The standard language, formulated in  the 16th century, combines features of western and southeastern dialects.  Polish is written in the Latin alphabet and utilizes both digraphs (combi�  nations of letters) and diacritics to distinguish its fairly elaborate reper�  tory of consonants. Stress is fixed on the next-to-last syllable.</p><p>Polish Succession, War of the (1733-38) European conflict waged  ostensibly to determine the successor to Augustus II. Austria and Russia  supported his son Augustus III, while most Poles, France, and Spain sup�  ported Stanislav/ I. a former Polish king (1704-09) and father-in-law of  France�s Louis XV. Stanislaw was elected king in 1733, but a Russian  threat forced him to flee, and Augustus was elected in his place. France,  with Sardinia and Spain, declared war on Austria (1733), seeking to  reclaim territory in Italy held by Austria. An inconclusive campaign ended  in the preliminary Peace of Vienna (1735), which redistributed the dis�  puted Italian territory and recognized Augustus as king. A final treaty was  signed in 1738.</p><p>Politburo \'pa-l9t-,byur-o\ Supreme policy-making body of the Com�  munist Party of the Soviet Union, the model for the politburos in other  countries. The first Politburo, created in 1917 to provide leadership dur�  ing the Bolshevik uprising, was dissolved when the coup was accom�  plished. The party congress of 1919 instructed the Central Committee to  elect a new Politburo, which soon overshadowed the Central Committee  in power. In 1952 it was replaced by a larger Presidium of the Central  Committee; after Joseph Stalin�s death, stress was placed on �collective  leadership� to correct for his abuses. The name Politburo was revived in  1966. Its members included the general secretary of the Communist Party,  the minister of defense, the head of the KGB, and the heads of the most  important republics or urban party branches. It was dissolved with the  breakup of the Soviet Union in 1991.</p><p>Politian \po-Ti-shon\ orig. Angelo Poliziano or Angelo  Ambrogini (b. July 14, 1454, Montepulciano, Tuscany�d. Sept. 28/29,  1494, Florence) Italian poet and humanist. He demonstrated his poetic  abilities early and became a friend and protege of Lorenzo de� Medici.  One of the foremost classical scholars of the Renaissance, he produced  between 1473 and 1478 Latin and Greek verses that are among the best  examples of humanist poetry. He was also, with Lorenzo, a leader in the  revaluation of literature in Italian. His vernacular works include Stanzas  Begun for the Tournament of the Magnificent Giuliano de � Medici (1475�  78), a masterpiece in ottava rima, and the drama Orfeo (1480).</p><p>political action committee (PAC) In U.S. politics, an organization  whose purpose is to raise and distribute campaign funds to candidates  seeking political office. PACs rose to prominence after the Federal Elec�  tion Campaign Act (1971) limited the amount of money any corporation,  union, or private individual could give to a candidate. PACs were able to  circumvent these limits by soliciting smaller contributions from a much</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>political convention &#x25BA; pollack I 1521</p><p>larger number of individuals. During the late 20th and early 21st centu�  ries the vast amounts of money raised by PACs greatly increased the cost  of running for office and led to efforts to reform this method of financing  campaigns.</p><p>political convention or party conference In politics, a meeting  of members of a political party at the local, state, or national level to select  party leaders and candidates for office and to determine party policy. Dur�  ing presidential election years in the U.S., the main parties hold conven�  tions that serve to showcase their presidential and vice presidential  candidates and to boost the morale of party members for the campaigns  that follow. Conventions were instituted in the U.S. in the 1830s to replace  the often exclusive and secretive caucus system; it was hoped that the  conventions� openness would make them less vulnerable to control by  party bosses. Most candidates for political office at all levels in the U.S.  are now nominated through primary elections, and the conventions merely  ratify the candidates already selected by the voters. Political parties in  other countries (e.g., Great Britain) often hold annual party conferences.</p><p>political economy Academic discipline that explores the relationship  between individuals and society and between markets and the state, using  methods drawn from economics, political science, and sociology. The  term is derived from the Greek terms polis (city or state) and oikonomos  (one who manages a household). Political economy is thus concerned with  how countries are managed, taking into account both political and eco�  nomic factors. The field today encompasses several areas of inquiry,  including the politics of economic relations, domestic political and eco�  nomic issues, the comparative study of political and economic systems,  and the study of international political economy.</p><p>political machine In U.S. politics, a political organization that con�  trols enough votes to maintain political and administrative control of its  community. The rapid growth of cities in the 19th century created huge  problems for city governments, which were often poorly organized and  unable to provide services. Enterprising politicians were able to win sup�  port by offering favours, including patronage jobs and housing, in  exchange for votes. Though machines often helped to restructure city  governments to the benefit of their constituents, they just as often resulted  in poorer service (when jobs were doled out as political rewards), cor�  ruption (when contracts or concessions were awarded in return for kick-  backs), and aggravation of racial or ethnic hostilities (when the machine  did not reflect the city�s diversity). Reforms, suburban flight, and a more  mobile population with fewer ties to city neighbourhoods have weakened  machine politics. Famous machines include those of William AAarcy Tweed  (New York), James Michael Curley (Boston), Thomas Pendergast (Kansas  City, Mo.), and Richard J. Daley (Chicago). See also civil service.</p><p>political party Group of persons organized to acquire and exercise  political power. Formal political parties originated in their modern form  in Europe and the U.S. in the 19th century. Whereas mass-based parties  appeal for support to the whole electorate, cadre parties aim at attracting  only an active elite; most parties have features of both types. All parties  develop a political program that defines their ideology and sets out the  agenda they would pursue should they win elective office or gain power  through extraparliamentary means. Most countries have single-party, two-  party, or multiparty systems (see party system). In the U.S., party candi�  dates are usually selected through primary elections at the state level.</p><p>political philosophy Branch of philosophy that analyzes the state and  related concepts such as political obligation, law, social justice, and con�  stitution. The first major work of political philosophy in the Western tra�  dition was Plato�s Republic. Aristotle�s Politics is a detailed empirical  study of political institutions. The Roman tradition is best exemplified by  Cicero and Polybius. St. Augustine�s City of God began the tradition of  Christian political thinking, which was developed by Thomas Aquinas.  Niccolo Machiavelli studied the nature and limits of political power. Tho�  mas Hobbes�s Leviathan (1651) raised the problem of political obligation  in its modem form. Hobbes was followed by Benedict de Spinoza, John  Locke, and Jean-Jacques Rousseau in the exposition of a social-contract  theory. This was rejected by David Hume and also by G.W.F. Hegel, whose  Philosophy of Right (1821) was fundamental for 19th-century political  thought. Hegel�s defense of private property stimulated Karl Marx�s cri�  tique of it. John Stuart Mill developed Jeremy Bentham�s utilitarian theory  of law and political institutions, so as to reconcile them with individual  liberty. In the 20th century John Dewey sought to counteract the dehu�  manizing aspects of modem capitalist society through a freer form of</p><p>education. Until the end of the Cold War, the field of political philoso�  phy was characterized by a division between Marxists and more tradi�  tional liberal thinkers, as well as by disagreements between left- and  right-leaning liberals, such as John Rawls and Robert Nozick (1938�  2002), respectively. From the 1970s, feminist political philosophy drew  attention to the apparent gendered nature of many concepts and problems  in Western political philosophy, especially autonomy, rights, liberty, and  the public-private distinction.</p><p>political science Academic discipline concerned with the empirical  study of government and politics. Political scientists have investigated the  nature of states, the functions performed by governments, voter behaviour,  political parties, political culture, political economy, and public opinion,  among other topics. Though it has roots in the political philosophies of  Plato and Aristotle, political science in the modern sense did not begin until  the 19th century, when many of the social sciences were established. Its  empirical and generally scientific orientation is traceable to the work of  Henri de Saint-Simon and Auguste Comte. The first institution dedicated to its  study, the Free School of Political Science, was founded in Paris in 1871.</p><p>polka Lively couple dance of Bohemian folk origin. The polka (Czech  for �Polish woman�) is characterized by three quick steps and a hop and  is danced to music in 2 A, or duple, time. It originated in the early 19th  century and became popular in ballrooms across Europe and in North and  South America. It has remained popular into the 21st century as both a  folk dance and a ballroom dance.</p><p>poll tax Tax of a uniform amount levied on each individual. The most  famous British poll tax was the one levied in 1380, a main cause of the  1381 Peasants' Revolt. In the U.S., poll taxes were used as a voting pre�  requisite in the southern states; when payment was made a prerequisite  to voting, impoverished blacks (and often poor whites) were effectively  denied the vote. In 1966 the U.S. Supreme Court ruled that states could  not levy a poll tax as a prerequisite for voting in state and local elections.</p><p>pollack or pollock Vpa-tak\ Either of two commercially important  North Atlantic species of food fish in the COD family (Gadidae). Pollachius  (or Gadus) virens, called saithe or coalfish in Europe, is deep green with a  pale belly. It has a small chin barbel (fleshy protuberance) and three dorsal  and two anal fins. A carnivorous, lively, usually schooling fish, it grows to  about 3.5 ft (1.1 m) long and weighs up to 35 lbs (16 kg). The other species,  Theragra chalcogramma, or walleye pollack, closely resembles P. virens.</p><p>1795, Mecklenburg county, N.C.,</p><p>Polk, James K(nox) (b. Nov. 2,</p><p>U.S.�d.

A proponent of western  expansion, he openly laid claim to  the whole territory that extended as  far north as latitude 54� 40� with the  slogan �Fifty-four Forty or Fight�</p><p>(see Oregon Question). Elected at  the age of 49, the youngest president  to that time, he successfully con�  cluded the Oregon border dispute  with Britain (1846) and secured pas-  sage of the Walker Tariff Act (1846),</p><p>which lowered import duties and helped foreign trade. He led the pros�  ecution of the Mexican War, which resulted in large territorial gains but  reopened debate over the extension of slavery. His administration also  established the Department of the Interior, the U.S. Naval Academy, and  the Smithsonian Institution; oversaw revision of the treasury system; and  proclaimed the validity of the Monroe Doctrine. Though an efficient and  competent president and deft in his handling of Congress, he was  exhausted by his efforts and did not seek reelection; he died three months  after leaving office.</p><p>James K.

Anto�  nio and Piero di Jacopo d'Antonio Benci (respectively b. Jan.  17, 1432/33, Florence, Republic of Florence�d. Feb. 4, 1498, Rome; b.  1443, Florence�d. 1496, Rome) Italian sculptors, painters, engravers,  and goldsmiths. Antonio probably trained in goldsmithing and metalwork�  ing with Lorenzo Ghiberti, while Piero may have studied painting with  Andrea del Castagno. The brothers collaborated consistently after 1460,  producing their works under a combined signature, and their individual  contributions are hard to determine. Antonio is recognized as a superb  draftsman and was among the first to practice anatomical dissection in the  study of the human form; Piero�s individual work is less artistically sig�  nificant. In Florence they created an altarpiece in San Miniato al Monte  and The Martyrdom of St. Sebastian (1475) in the Pucci Chapel of the  Church of the Santissima Annunziata. In Rome their works included the  tombs of Popes Sixtus IV and Innocent VIII. Antonio�s famous Battle of  Nudes is one of the largest and most important Italian engravings of the  15 th century.</p><p>pollen Mass of microscopic spores in a seed plant that appears usually  as a fine dust. Each pollen grain is tiny, varies in shape and structure, is  formed in the stamens in seed plants, and is transported by various means  (see pollination) to the pistil, where fertilization occurs. The outer layer of  a pollen grain is very resistant to disintegration; treatment with intense  heat, strong acids, or strong bases has little effect on it. Because the grains  often are very distinctive, some plant species may be identified by their  pollen grains alone. Common components of both recent and ancient geo�  logic sediments, pollen grains have provided much information on the  origin and geologic history of plant life on land. Pollen is produced in  such quantities that it is a significant part of the airborne components of  earth�s atmosphere. The protein-containing substance in many pollen  grains (e.g., ragweed and many grasses) causes the allergic reaction com�  monly known as hay fever.</p><p>pollination Transfer of pollen grains in seed plants from the stamens,  where they form, to the pistil. Pollination is required for fertilization and  the production of seeds. On the surface of the pistil the pollen grains ger�  minate (see germination) and form pollen tubes that grow downward  toward the ovules. During fertilization, a sperm cell in a pollen tube fuses  with the egg cell of an ovule, giving rise to the plant embryo. The ovule  then grows into a seed. Since the pollen-bearing parts of the stamens are  rarely in direct contact with the pistil, plants commonly rely on external  agents for pollen transport. Insects (especially bees) and wind are the most  important pollinators; other agents include birds and a few mammals  (notably certain bats). Water transport of pollen is rare. An egg may be  fertilized by self-pollination (when the sperm comes from pollen produced  by the same flower or by another flower on the same plant) or by cross�  pollination (when the sperm comes from the pollen of a different plant).</p><p>Pollini, Maurizio (b. Jan. 5, 1942, Milan, Italy) Italian pianist. He  made his debut at age nine and won the Warsaw Chopin Competition in  1960. He first played in the U.S. in 1968. His recordings and performances  range from works by Johann Sebastian Bach to Ludwig van Beethoven to  Karlheinz Stockhausen. His combination of intellectual seriousness and  extraordinary technical brilliance have given him a unique standing in the  concert world.</p><p>polliwog See tadpole  pollock See poliack</p><p>Pollock, Sir Frederick, 3rd Baronet (b.

He was noted for his History of English Law Before the Time of  Edward I (1895; written with Frederic W. Maitland) and several standard  textbooks. He maintained a 60-year correspondence with Oliver Wendell  Holmes, Jr.; the Holmes-Pollock Letters were published in 1941.</p><p>Pollock \'pa-bk\, (Paul) Jackson (b. Jan. 28, 1912, Cody, Wyo.,  U.S.�d. Aug. 11, 1956, East Hampton, N.Y.) U.S. painter. He grew up  in California and Arizona. In the early 1930s he studied in New York City  under Thomas Hart Benton, and later he was employed on the WPA Fed�  eral Art Project. In 1945 he married the artist Lee Krasner. Two years later,  after several years of semiabstract work stimulated by psychotherapy,  Pollock began to lay his canvas on the floor and pour or drip paint onto  it in stages. This process permitted him to record the force and scope of  his gestures in trajectories of enamel or aluminum paint that �veiled� the</p><p>figurative elements found in his ear�  lier work. The results were huge  areas covered with complex and  dynamic linear patterns that fuse  image and form and engulf the vision  of the spectator in their scale and  intricacy. Pollock believed that art  derived from the unconscious and  judged his work and that of others on  its inherent authenticity of personal  expression. He became known as a  leading practitioner of Abstract  Expressionism, particularly the form  known as action painting. Champi�  oned by critic Clement Greenberg and  others, he became a celebrity. When  he died in a car crash at 44, he was  one of the few American painters to  be recognized during his lifetime and  afterward as the peer of 20th-century  European masters of modem art.</p><p>Pollock v.

Players use mal�  lets with long flexible handles to drive a wooden ball through goalposts.  It was first played in Persia in the 6th century bc; from there it spread to  Arabia, Tibet (polo is Balti for �ball�). South Asia, and the Far East. The  first British polo clubs were formed in India in the mid-19th century; the  game came to the U.S. a few decades later. Polo has long been primarily  played by the wealthy, because of the expense of acquiring and main�  taining a stable of polo �ponies� (actually full-sized adult horses, bred for  docility, speed, endurance, and intelligence). The standard team is made  up of four players whose positions are numbered 1-4. A game consists  of six 7.5-minute periods called chukkers or chukkas. The field is 300  yards (274.3 m) long by 160 yards (146.3 m) wide; an indoor version of  the game is played on a smaller field.</p><p>Polo, Marco (b. c. 1254, Venice or Curzola, Venetian Dalmatia�d. Jan.  8, 1324, Venice) Venetian merchant  and traveler who journeyed from  Europe to Asia (1271-95). Born into  a Venetian merchant family, he  joined his father and uncle on a jour�  ney to China, traveling along the Silk  Road and reaching the court of Kublai  Khan c. 1274. The Polos remained in  China for about 17 years, and the  Mongol emperor sent Marco on sev�  eral fact-finding missions to distant  lands. Marco may also have gov�  erned the city of Yangzhou (1282�</p><p>87). The Polos returned to Venice in  1295, after sailing from eastern  China to Persia and then journeying  overland through Turkey. Captured  by the Genoese soon after his return,</p><p>Marco was imprisoned along with a  writer, Rustichello, who helped him  to write the tale of his travels.

The battle was fought near  Poltava, Ukr., between 80,000 Russian troops under Peter I the Great and  Aleksandr Menshikov and 17,000 Swedish troops under Charles XII. Despite  the lack of reinforcements for his depleted forces, Charles besieged Pol�  tava in May 1709. The Russians set up a countersiege line and forced the  Swedes to attack. Charles planned a daring charge through the Russian  line, but he had been injured, and his commanders failed to execute the  attack. The Russian counterattack killed or captured the entire Swedish  army except for Charles and 1,500 followers. Sweden�s defeat ended its  status as a major power and marked the beginning of Russian supremacy  in eastern Europe.</p><p>Polybius \p3-'lib-e-3s\ (b. c. 200, Megalopolis, Arcadia, Greece�d. c.  118 bc) Greek statesman and historian. Son of an Achaean statesman,  Polybius was one of 1,000 eminent Achaeans deported to Rome in 168  bc for supposed disloyalty to the Romans. There he became mentor to  Scipio Africanus the Younger, with whom he witnessed the destruction of  Carthage soon after his political detention had ended. When hostilities  broke out between Achaea and Rome, he negotiated for his countrymen  and sought to reestablish order. His reputation rests on his history of the  rise of Rome; of its 40 volumes, only 5 survive in their entirety.</p><p>polychaete \'pa-le-,ket\ Any of about 5,400 species of marine worms  of the annelid class Polychaeta, having a segmented body with many setae  (bristles) on each segment. Species, often brightly coloured, range from  less than 1 in. (2.5 cm) to about 10 ft (3 m) long. Most body segments  bear two bristly parapodia (lobelike outgrowths). The head has short sen�  sory projections and tentacles. Adults may be free-swimming or seden�  tary; larvae are free-swimming. Found worldwide, polychaetes are  important for turning over sediment on the ocean bottom. One species,  the bloodworm, is a popular saltwater fish bait. See also tube worm.</p><p>Polyclitus or Polycleitus or Polykleitos V.pa-li-'kll-tosV (fl. 5th cen�  tury bc, Greece) Greek sculptor. His Spear Bearer (c. 440 bc) was known  as �the Canon� because it illustrated his book of that name, which set  forth his theory of the ideal mathematical proportions of the human body  and proposed that the sculptor strive for a dramatic counterbalance  between the relaxed and tense body parts and the directions in which they  move. His balanced and rhythmical bronze statues of young athletes, such  as Man Tying on a Fillet (c. 420 bc), demonstrated his principles and freed  Greek sculpture from its tradition of rigid frontal poses. With Phidias,  Polyclitus was the most important Greek sculptor of his age.</p><p>Polycrates Xpo-'lik-ro-.tezV (fl. 6th century bc) Tyrant of the Aegean  island of Samos c. 535-522 bc. He seized sole control during a festival  of Hera, eliminating his two brothers, who shared his power. He quickly  became notorious for piracy, as he sought to dominate nearby islands and  Ionia. Initially a supporter of Egypt, he joined the Persians against Egypt  in 525. Attempts by his opponents to remove him were unsuccessful until  the Persian governor of Sardis lured him to the mainland and had him  crucified. Polycrates brought wealth and prominence to Samos and was a  patron of writers, including Anacreon.</p><p>polycystic ovary syndrome or Stein-Leventhal syndrome</p><p>Endocrine disorder in women, characterized by high androgen levels and  infrequent or absent ovulation (see reproductive system). It causes a high  proportion of female infertility cases. Symptoms vary but often include  hirsutism, acne, and obesity. Menstruation may be irregular, absent, or  excessive. The ovaries are usually enlarged and contain cysts. The disease  may remain undiagnosed until a woman tries to conceive. The underly�  ing cause is not fully understood. Treatment attempts to reduce androgen  production. Infertility may be treated with clomiphene citrate or gona�  dotropins to induce ovulation or with laparoscopy.</p><p>polyester Organic compound, any of a class of polymers formed by ester  linkages between monomers. They are usually prepared from equivalent  amounts of glycols and dibasic carboxylic acids, which undergo conden�  sation polymerization to produce the polyester and water. Polyesters are  strong, colourfast, and resistant to corrosion and chemical attack but tend</p><p>to build up a static electric charge. In addition to the familiar fibres and  films (e.g., Dacron, Mylar), polyesters are used to make reinforced plas�  tics, automotive parts, boat hulls, foams, laminates, tapes, piping, bottles,  disposable filters, encapsulations, and coatings.</p><p>polyethylene (PE) Any of the polymers of ethylene, the largest class of  plastics. Its simple basic structure, of ethylene monomers, can be linear  (high-density and ultrahigh-molecular-weight polyethylene; HDPE and  UHMWPE, respectively) or branched to a greater or lesser degree (low-  density and linear low-density polyethylene; LDPE and LLDPE, respec�  tively). The branched polyethylenes have similar structural characteristics  (e.g., low crystalline content), properties (high flexibility), and uses (pack�  aging film, plastic bags, mulch, insulation, squeeze bottles, toys, and  housewares). HDPE has a dense, highly crystalline structure of high  strength and moderate stiffness; uses include beverage bottles, liquid  detergent jugs, crates, barrels, and luggage. UHMWPE is made with  molecular weights 6-12 times that of HDPE; it can be spun and stretched  into stiff, highly crystalline fibres with a tensile strength many times that  of steel; uses include bulletproof vests.</p><p>polygamy \p9-'li-g3-me\ Marriage to more than one spouse at a time.  Although the term may also refer to polyandry (marriage to more than  one man) it is often used as a synonym for polygyny (marriage to more  than one woman), which appears to have once been common in most of  the world and is still found widely in some cultures. Polygyny seems to  offer the husband increased prestige, economic stability, and sexual com�  panionship in cultures where pregnancy and lactation dictate abstinence,  while offering the wives a shared labour burden and an institutionalized  role where a surplus of unmarried women might otherwise exist. The  polygynous family is often fraught with bickering and sexual jealousy; to  preserve harmony, one wife may be accorded seniority, and each wife and  her children may have separate living quarters. Polyandry is relatively  rare; in Tibet and Nepal, where brothers may marry a single woman, the  practice serves to limit the number of descendants and keep limited land  within the household.</p><p>Polygnotus or Polygnotos N.pa-lig-'no-tosX (b. c. 500, Thasos,  Thrace� d. c. 440 bc, Athens, Greece) Greek painter. None of his works  are extant, but accounts exist of monumental wall paintings in a severely  Classical style at the hall of the Cnidians at Delphi: Sack of Troy and  Ulysses Visiting Hades. His compositions were noted for the expression  of emotion on faces and for the distribution of figures throughout the  composition rather than on a single base line, as was the convention of  the day.</p><p>polygon In geometry, any closed curve consisting of a set of line seg�  ments (sides) connected such that no two segments cross. The simplest  polygons are triangles (three sides), quadrilaterals (four sides), and pen�  tagons (five sides). If none of the sides, when extended, intersects the  polygon, it is a convex polygon; otherwise it is concave. A polygon with  all sides equal is equilateral. One with all interior angles equal is equi�  angular. Any polygon that is both equilateral and equiangular is a regular  polygon (e.g., equilateral triangle, square).</p><p>polygraph See lie detector</p><p>polyhedron \,pa-le-'he-dr3n\ In Euclidean geometry, a three-  dimensional object composed of a finite number of polygonal surfaces  (faces). Technically, a polyhedron is the boundary between the interior  and exterior of a solid. In general, polyhedrons are named according to  number of faces. A tetrahedron has four faces, a pentahedron five, and so  on; a cube is a six-sided regular polyhedron (hexahedron) whose faces  are squares. The faces meet at line segments called edges, which meet at  points called vertices. See also Platonic solid; Euler's formula.</p><p>Polykleitos See Polyclitus</p><p>polymer Vpa-lo-morX Any of a class of natural or synthetic substances  composed of macromolecules that are multiples of monomers. The mono�  mers need not all be the same or have the same structure. Polymers may  consist of long chains of unbranched or branched monomers or may be  cross-linked networks of monomers in two or three dimensions. Their  backbones may be flexible or rigid. Some natural inorganic materials (e.g.,  the minerals diamond, graphite, and feldspar) and certain man-made inor�  ganic materials (e.g., glass) have polymer-like structures. Many impor�  tant natural materials are organic polymers, including cellulose (from  sugar monomers; see polysaccharide), lignin, rubber, proteins (from amino  acids), and nucleic acids (from nucleotides). Synthetic organic polymers</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1524 I polymerase chain reaction &#x25BA; polyvinylchloride</p><p>include many plastics, including polyethylene, the nylons, polyurethanes,  polyesters, vinyls (e.g., PVC), and synthetic rubbers. The silicone polymers,  with an inorganic backbone of silicon and oxygen atoms and organic side  groups, are among the most important mixed organic-inorganic com�  pounds.</p><p>polymerase \pa-'b-m3- I ras\ chain reaction (PCR) Laboratory  technique used to make numerous copies of specific DNA segments  quickly and accurately. These are needed for various experiments and  procedures in molecular biology, forensic analysis (DNA fingerprinting),  evolutionary biology (to amplify DNA fragments found in ancient speci�  mens), and medicine (to diagnose genetic disease or detect low viral  counts). Invented by Kary Mulus, PCR requires a DNA template (as little  as one molecule) to copy, nucleotides to build the copies, and the enzyme  DNA polymerase to catalyze the formation of bonds between the nucle�  otide monomers. Each three-step cycle (separating the two strands of the  DNA double helix, marking the ends of the segment to be copied, and  catalyzing the formation of bonds), which takes only minutes to complete,  doubles the number of DNA strands present in the reaction medium. Rep�  etition of this cycle many times results in an exponential increase in the  amount of DNA.</p><p>polymerization 'ypo-.li-mo-ro-'za-shonN Any process in which mono�  mers combine chemically to produce a polymer. The monomer molecules�  which in the polymer usually number from at least 100 to many  thousands�may or may not all be the same. In nature, enzymes carry out  polymerization under ordinary conditions to form proteins, nucleic acids,  and carbohydrate polymers; in industry, the reaction is usually done with  a catalyst, often under high pressure or heat. In addition polymerization,  monomers are added successively to the reactive ends of a growing poly�  mer molecule, similar to adding links to a chain; during the reactions, no  by-products are formed. In condensation polymerization, growth of the  polymer advances stepwise�monomers having reactive functional groups  combine into larger molecules with their own functional groups; each  reaction splits off a small molecule, often water, as a by-product.</p><p>polymorphism Discontinuous genetic variation that results in the  occurrence of several different forms or types of individuals among the  members of a single species. The most obvious example of polymorphism  is the separation of most higher organisms into male and female sexes.  Another example is the different blood types in humans. A polymorphism  that persists over many generations is usually maintained because no one  form has an overall advantage or disadvantage over the others in terms  of natural selection. Some polymorphisms have no visible manifestations.  The castes that occur in social insects are a special form of polymorphism  that results from differences in nutrition rather than from genetic varia�  tion.</p><p>Polynesia ^pa-lo-'ne-zhsN Island group, scattered across a huge trian�  gular area of the east-central Pacific Ocean. A subdivision of Oceania,  Polynesia includes New Zealand, Hawaii, Samoa, the Line Islands, French  Polynesia, the Cook Islands, the Phoenix Islands, Tuvalu, Tonga, and Easter  Island. Fiji is sometimes included because of its Polynesian population.  The islands are mostly small coral atolls; some are of volcanic origin.  Most of the inhabitants are Polynesians, some of whom might be related  to the Malay. Their languages belong to a subfamily of the Austronesian  languages. Contact with European culture began in the late 1700s with  the arrival of Spanish explorers and radically altered life in Polynesia.  Colonizers, imposing Western belief systems and cultural ways, effec�  tively wiped out local traditions and customs. Samoa and Tonga retain  more of the traditional culture than the other islands.</p><p>polynomial In algebra, an expression consisting of numbers and vari�  ables grouped according to certain patterns. Specifically, polynomials are  sums of monomials of the form ay! 1 , where a (the coefficient) can be any  real number and n (the degree) must be a whole number. A polynomial�s  degree is that of its monomial of highest degree. Like whole numbers,  polynomials may be prime or factorable into products of primes. They  may contain any number of variables, provided that the power of each  variable is a nonnegative integer. They are the basis of algebraic equation  solving. Setting a polynomial equal to zero results in a polynomial equa�  tion; equating it to a variable results in a polynomial function, a particu�  larly useful tool in modeling physical situations. Polynomial equations  and functions can be analyzed completely by methods of algebra and cal�  culus.

Shape varies widely; it may have a stalk or many  lobes. Polyps most often occur in the nose, urinary bladder, and digestive  tract, especially in the rectum and colon. Symptoms, if any, depend on  location and size; they may result from pressure or from blockage of a  passage. Polyps occasionally bleed. Because a small percentage are pre�  cursors to cancers or actually contain cancers, it is advisable to have them  removed and examined microscopically and to undergo routine colonos�  copy after age 50.</p><p>polyp In zoology, one of two principal cnidarian body forms and, some�  times, an individual in a bryozoan colony. The cnidarian polyp body is a  hollow cylindrical structure. The lower end attaches to another body or  surface. The upper, or free, end is directed upward and has a mouth sur�  rounded by extensible tentacles that bear stinging structures called nem-  atocysts. The tentacles capture prey, which is then drawn into the mouth.  The polyp may be solitary (see sea anemone) or colonial (see coral). The  body wall consists of three dermal layers. The other cnidarian body form  is the MEDUSA.</p><p>Polyphemus V.pa-lo-'fe-mssV In Greek mythology, a Cyclops. He was  the son of Poseidon and the nymph Thoosa. When Odysseus and his com�  panions were cast ashore on the coast of Sicily, Polyphemus imprisoned  them in his cave with the intention of eating them. Odysseus got the giant  drunk and then blinded him by plunging a burning stake into his single  eye. When Polyphemus opened his cave in the morning, Odysseus and  the six men the giant had not yet devoured made their escape by clinging  to the bellies of sheep let out to pasture.</p><p>polyphony See counterpoint</p><p>polyploidy See ploidy</p><p>polysaccharide V.pa-le-'sa-ko-.ridX Any of a large class of long-chain  sugars composed of monosaccharides. Because the chains may be  unbranched or branched and the monosaccharides may be of one, two, or  occasionally more kinds, polysaccharides can be categorized in various  ways. Cellulose, starch, glycogen, and dextran are all polysaccharides of  glucose, with different configurations. Pectins are composed of a galac�  tose derivative, chitin of a glucose derivative. Connective tissues, joint  fluid, and cartilage contain two-component polysaccharides, including  heparin. See also oligosaccharide.</p><p>polysiloxane See silicone</p><p>polytheism Belief in many gods. Though Judaism, Christianity, and  Islam are monotheistic (see monotheism), most other religions throughout  history have been polytheistic. The numerous gods may be dominated by  a supreme god or by a small group of powerful gods. The gods originated  as abstractions of the forces of nature such as the sky or the sea and of  human and social functions such as love, war, marriage, or the arts. In  many religions the sky god is powerful and all-knowing (e.g., Dievs), and  the earth goddess is maternal and associated with fertility. Gods of death  and the underworld (e.g., Osiris and Hel) are also important. In addition  to many gods, polytheistic religions generally also include malevolent or  benevolent spiritual forces or powers. See also god and goddess.</p><p>polyurethane Any of a class of very versatile polymers that are made  into flexible and rigid foams, fibres, elastomers (elastic polymers), sur�  face coatings, and adhesives. They are produced by reacting a diisocyan�  ate (a compound with two functional groups of the type �NCO) with a  diol (a compound with two hydroxyl, or �OH, groups). Foamed poly�  urethanes, used for insulation and mattress and upholstery filler, are made  with organic compounds containing carboxyl groups, causing a reaction  that liberates carbon dioxide bubbles throughout the product. Spandex  fibres are highly elastic and have replaced natural and synthetic rubber  fibres for many textile purposes. Polyurethane elastomers are made into  auto parts, rollers, flexible molds, medical equipment, and shoe soles.  Polyurethane surface coatings are applied as sealants to wood, concrete,  and machine parts and as linings for tanks and pipes; moisture-curing  polyurethane resin is used as a general-purpose waterproof glue.</p><p>polyvinyl chloride See PVC</p></section><section><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Pombal &#x25BA; Pompeius Magnus Pius I 1525</p><p>Pombal \p3-'bal\, Sebastiao de Carvalho, marquess de (b.</p><p>May 13, 1699, Lisbon, Port.�d. May 8, 1782, Pombal) Portuguese  reformer. After serving as ambassador to England and Vienna, he became  chief minister to King Joseph and came to dominate Portuguese politics  (1750-77). He encouraged industry and commerce and stimulated trade  with Brazil. After the 1755 earthquake that devastated Lisbon, he orga�  nized aid and reconstruction efforts. He restricted the power of the nobil�  ity, had the Jesuits imprisoned or deported to Rome (1759), reorganized  Portugal�s army, and reformed the university educational system. After  Joseph�s death (1777), Pombal�s power disappeared; under Queen Maria  I, he was accused of abuse of power and banished from Lisbon to his  estates.</p><p>pomegranate Vpa-ms-.gra-nsA Fruit of Punica granatum, a bush or  small tree of Asia, which with a little-known species from the island of  Socotra constitutes the family Punicaceae. Native to Iran and long culti�  vated around the Mediterranean and in India, it also grows in the warmer  parts of the New World. The orange-sized and obscurely six-sided fruit  has smooth, leathery, brownish yellow to red skin. Several chambers con�  tain many thin, transparent vesicles of reddish, juicy pulp, each contain�  ing an angular, elongated seed. The fruit is eaten fresh, and the juice is  the source of the grenadine syrup used in flavourings and liqueurs. The  plant grows 16-23 ft (5-7 m) tall and has elliptical, bright green leaves  and handsome orange-red flowers. Throughout the Orient, the pomegran�  ate has since earliest times occupied a position of importance alongside  the grape and the fig. It is mentioned in the Bible, by the Prophet Muham�  mad, and in Greek mythology.</p><p>Pomerania V.pa-mo-'ra-ne-oX Historical region, northeastern Europe,  on the Baltic Sea between the Oder and Vistula rivers. Occupied by Slavs  and other peoples, it was ruled by Polish princes in the 10th century. Ger�  man immigration into western and central Pomerania began in the late  12th century, and Polish dukes ruled this area under the suzerainty of the  Holy Roman Empire until the 17th century. Eastern Pomerania was held  by the Knights of the Teutonic Order from 1308 until it was reconquered  by Poland in 1454. The elector of Brandenburg acquired the duchies in  1637. Prussia united western and central Pomerania in 1815 as the prov�  ince of Pommern. Most of the area is now in Poland; its westernmost  section is in eastern Germany.</p><p>Pomeranian X.pa-mo-'ra-ne-onV Breed of toy dog developed from the  same sled-dog ancestors as the Kee-  shond, Samoyed, and Norwegian  elkhound. It is said to have been bred  down in size from a 30-lb (14-kg)  dog in the duchy of Pomerania in the  early 19th century. Spirited but doc�  ile, it has a foxlike head and small,  erect ears. Its long coat, especially  full on the neck and chest, is white,  black, brown, or reddish brown. It  stands about 6-7 in. (14-18 cm) and  weighs about 3-7 lbs (1.5-3 kg).</p><p>pommel horse or side horse</p><p>Gymnastics event for men. It uses a padded rectangular apparatus sup�  ported by legs and with two pommels (U-shaped handles) on the top. The  gymnast performs various swinging and balancing feats, holding himself  over the horse by means of the pommels or by grasping the front (neck),  centre (saddle), or rear (croup) of the horse. The apparatus stems from a  wooden horse used by the Romans to teach mounting and dismounting.</p><p>Porno North American Indian people living in northern California, U.S.  The name Porno, which may have been derived from the name of a vil�  lage, was given to seven distinct Hokan-speaking peoples who inhabited  the Russian River valley. Fish, waterfowl, deer, and wild plant foods were  plentiful in this region. Coastal Porno constructed dwellings of heavy  timber and bark; inland Porno used poles, brush, and grass. Porno religion  involved secret societies, dances, rituals, and impersonations of spirits.  Porno basketry is often considered among the finest in the world. About  3,000 Porno live in some 20 communities within their original territory.</p><p>Pomona \p3-'mo-n3\ Ancient Roman goddess of fruit. Vertumnus, god  of the seasons, fell in love with her, but she rejected him and all other  suitors, preferring to cultivate her orchards. Refusing to give up, Vertum�  nus came to her in the form of an old woman and pleaded his case so  effectively that Pomona changed her mind and agreed to be his.</p><p>Pompadour Vpam-po-.dorV Jeanne-Antoinette Poisson, mar�  chioness de known as Madame  de Pompadour (b.

She, the king,  and her brother, appointed director of  the king�s buildings, planned and  built the Ecole Militaire and the  Place de la Concorde in Paris, the  Petit Trianon Palace at Versailles,  and many other buildings. She and  Louis also encouraged painters,  sculptors, and craftsmen, making her  20 years in power the height of artis�  tic taste. Her political influence was  less astute; the alliance with Austria  against the German Protestant  princes that she urged led to the  disastrous Seven Years' War.</p><p>pompano Vpam-po-.noX Any of several species of deep-bodied, tooth�  less, silvery fishes in the order Perci-  formes (especially in the genus  Trachinotus, family Carangidae)  inhabiting warm coastal waters  worldwide.

Sept. 28,48 bc, Pelusium, Egypt) States�  man and general of the Roman republic. His early military career was  illustrious. He fought effectively for Sulla against Marius in the Social  War, reconquered Spain (76-71), destroyed utterly the army of Sparta-  cus (71), destroyed the pirates of the eastern Mediterranean (from 67),  defeated Mithradates (63), and consolidated and extended the eastern  provinces and frontier kingdoms. In 61 he formed the First Triumvirate with  Julius Caesar and Marcus Licinius Crassus. After Crassus�s death in 53,  Pompey and Caesar fell out. By 52, with Rome in a state of anarchy,  Pompey was named sole consul. In 49 Caesar defied the Senate and pro�  voked the civil war by crossing the Rubicon in pursuit of Pompey, who  fled east with his navy. Defeated at the Battle of Pharsalus (48), Pompey  fled with his fleet to Egypt, not realizing the Egyptians would take Cae�  sar�s side, and was killed as he prepared to step on land from the boat  they had sent to bring him ashore.</p><p>Pompidou \'pam-pi-,du\, Georges (-Jean-Raymond) (b.

After  joining the Rothschild bank in Paris,  he rose rapidly to become director  general (1959). As de Gaulle�s chief  aide (1958�59), he helped draft the  constitution of the Fifth Republic. He  secretly negotiated a cease-fire in the  Algerian War in 1961 and was  appointed premier the following  year. In 1968 he skillfully negotiated  an end to the French student-worker  strikes. Elected president of France  in 1969, he continued de Gaulle�s  policies.

When formally opened in 1977, the building attracted notoriety for its  brightly coloured exterior pipes, ducts, and other exposed architectural  elements, and it soon became one of the most visited cultural sites in the  world. Though primarily a museum for 20th-century visual arts, it also  houses temporary exhibitions, a library, a centre for industrial design, a  film museum, and a Centre for Musical and Acoustical Research.</p><p>Ponce de Leon V.pan-so-.da-le-'onX, Juan (b. 1460, Tierra de Campos  Palencia, Leon�d. 1521, Havana, Cuba) Spanish explorer. He may have  accompanied Christopher Columbus�s expedition in 1493 and later fought  in the West Indies (1502), becoming governor of eastern Hispaniola. He  colonized Puerto Rico (1508-09) and founded a settlement near modem  San Juan. Rumours of a fountain of youth in the Bahamas inspired him  to lead an expedition in 1513, but he landed instead on the northern coast  of Florida near modern St. Augustine. He sailed along Florida�s southern  and western coasts, then returned to Spain to secure the title of military  governor (1514). He sailed again to colonize Florida in 1521 but was  wounded in an Indian attack and died in Cuba.</p><p>Pondicherry Union territory (pop., 2001: 974,345), India. It was  formed in 1962 from the four former French colonies of Pondicherry,  Karikal, and Yanam, on the eastern seaboard, and Mahe, on the western</p><p>seaboard. With a total area of 190 sq mi (492 sq km), it is united by little  other than its colonial past and focus on tourism. The city of Pondicherry  is the administrative capital.</p><p>Pondicherry City (pop., 2001: 220,865), seaport, and capital of  Pondicherry union territory, southeastern India. Lying on the Coromandel  Coast, it originated as a French trade centre in 1674, when it was purchased  from a local ruler. The scene of fighting between the French and Dutch, it  was occupied by the British several times from 1761 before becoming a  French possession (1816-1954). A seaside tourist resort, it contains an  international study centre at a Hindu religious retreat, or ashram.</p><p>Pondoland Region, Eastern Cape province, southern Republic of South  Africa, on the coast of the Indian Ocean. It was settled at the end of the  16th century by the Pondo (Mpondo), a BANTU-speaking people. It was  annexed to Cape Colony in 1894. It occupies a narrow strip from the coast  to the interior plateaus in the west. The interior is rich cattle country with  fertile farmlands.</p><p>Pont-Aven \ 1 po n -to- , ven\ school Group of young painters who  espoused a style known as Synthetism and united under the tutelage of Paul  Gauguin at Pont-Aven, Brittany, France, in the late 1880s and early 1890s.  The artists included Emile Bernard, Charles Laval, Maxime Maufra, Paul  Serusier, Charles Filiger, Jacob Meyer de Haan, Armand Seguin, and Henri  de Chamaillard. Their paintings showed an overall simplification, a highly  expressive use of colour, and an intensely spiritual subject matter. When  Gauguin left for Tahiti, members of the school became increasingly  involved in developing the theories and techniques of Symbolism.</p><p>Pontchartrain Vpan-chor-.tranV Lake Lake, southeastern Louisiana,  U.S. It is 40 mi (64 km) long and 25 mi (40 km) wide, with an area of  630 sq mi (1,631 sq km). More a tidal lagoon than a lake, it is brackish  and teems with game fish. It is connected through Lake Borgne with the  Gulf of Mexico and by canal with the Mississippi River. It is spanned by the  Pontchartrain Causeway, two parallel road bridges which cross the lake  north of New Orleans and, at nearly 24 mi (39 km) in length, are the long�  est overwater bridges in the world.</p><p>Pontecorvo X.pan-to-'kor-vcA, Guido (b. Nov. 29, 1907, Pisa,  Italy�d. Sept. 24, 1999, near Zermatt, Switz.) Italian-born British geneti�  cist. In 1938, influenced by Hermann Joseph Muller, he designed a method  for studying genetic differences among species that usually produce ster�  ile hybrids when interbred. His technique permitted him to study evolu�  tionary divergence in the fruit fly. His conviction that research in microbial  genetics could lead to increased production of penicillin, much needed in  World War II, led him to the genetics of fungi, and in 1950 he found that  recombination of genes can occur in the fungus Aspergillus nidulans with�  out sexual reproduction. Nonsexual gene recombination became a useful  technique in exploring the nature of gene action.</p><p>Pontiac (b. c. 1720, on the Maumee River in present-day Ohio, U.S.�d.  April 20, 1769, near the Mississippi River at present-day Cahokia, Ill.)  Ottawa Indian chief. At first friendly with whites, Pontiac realized that his  people would lose their ancestral lands in the Great Lakes area if white  encroachment were not stopped. With a series of actions that came to be  known as Pontiac�s War (1763-64), he coordinated the attack on 12 for�  tified British posts by a confederacy of tribes, winning a great victory. He  himself led the attack on the fort at Detroit, in what is now Michigan,  U.S. Continuing British action took its toll, however, and in 1766 Pon�  tiac finally agreed to a peace treaty. His murder in 1769 by an Illinois  Indian provoked the vengeance of several northern Algonquian tribes,  resulting in the virtual destruction of the Illinois.</p><p>Pontifex See Quintus Mucius Scaevola</p><p>pontifex Member of a council of priests in ancient Rome. The pontifices  were responsible for administration of the jus divinum (laws concerning  religious practices). There were 3 pontifices under the monarchy, but by the  time of Julius Caesar the number had grown to 16, of which 1 was desig�  nated chief priest, or pontifex maximus. Also included in the collegium  (college) of pontifices were the Vestal Virgins. Among the duties of the pon�  tifices were regulation of the calendar and of expiatory rituals, consecration  of temples and sacred objects, superintendence of marriage and the family,  and administration of the laws of adoption and succession.</p><p>Pontoppidan \p6n-'top-e-dan\, Henrik (b.

His works, typically written in a cold,  aloof, epic style, present a comprehensive picture of his country and his  epoch. His earlier works are informed with a desire for social progress;  his later ones despair of its realization. His major novels include the  semiautobiographical Lucky Peter (1898-1904) and the five-volume cycle  The Realm of the Dead (1912-16). He shared the 1917 Nobel Prize for  Literature with Karl Gjellerup.</p><p>Pontormo Vpon-'tor-moV Jacopo da orig. Jacopo Carrucci (b.</p><p>May 24, 1494, Pontormo, Republic of Florence�buried Jan. 2, 1557,  Florence) Florentine painter. The son of a painter, he was apprenticed to  Leonardo da Vinci and later to Piero di Cosimo and Andrea del Sarto (who  exerted the greatest influence on him). The agitated, almost neurotic emo�  tionalism of his work reflects a departure from the balance and tranquil�  lity of the High Renaissance. His expressive style is sometimes considered  an early manifestation of Mannerism. Primarily a religious painter, he also  did sensitive portraits and was employed by the Medici family to decorate  their villa at Poggio a Caiano with mythological subjects.</p><p>Pontus Ancient district, northeastern Anatolia adjoining the Black Sea.  An independent kingdom with its capital at Amasia, it was established in  the 4th century bc. It continued expanding its borders until 66 bc, when  its last king, Mithradates VI Eupator, was defeated by the Roman general  Pompey the Great. It was incorporated into the Roman Empire in 63 bc.</p><p>pony Any of several breeds of small horses standing less than 14.2 hands  (57 in., 144 cm) high and noted for gentleness and endurance. Among the  common pony breeds are the Shetland; the stylish and hardy Welsh; the  high-stepping Welsh Cob; the Exmoor and Dartmoor, natives of the  English moors that are used to breed polo ponies; and the Highland, a  thick, gray saddle animal.</p><p>Pony Express (1860-61) U.S. system of mail delivery by horse and  rider relays. The 1,800-mi (2,900-km) route between St. Joseph, Mo., and  Sacramento, Calif., included 157 stations. Riders changed horses every 10  to 15 miles, and it took about 10 days to complete the route. The sponsoring  company of Russell, Majors, Wadell employed riders such as William F.  Cody and Pony Bob Haslam. The system provided an important mail link  with the West, but it was a financial failure and became obsolete after 18  months with the completion of the transcontinental telegraph system.</p><p>poodle German water retriever. Poodles have a long muzzle, hanging  ears, and docked tail. The dense,  solid-coloured, wiry topcoat covers a  woolly undercoat. Poodles� hair was  traditionally clipped to permit them  to swim efficiently when retrieving;  today they are usually clipped in  ornamental patterns. A dog with  unclipped hair, which forms ropelike  cords, is called a corded poodle. The  standard poodle is more than 15 in.</p><p>(38 cm) tall and weighs up to 70 lb  (32 kg); the miniature stands 10-15  in. (25.5-38 cm); the toy is under 10  in. (25.5 cm) and weighs about 7 lb  (3 kg). The poodle is the national dog  of France, where it was once trained  to scent and dig up truffles. Poodles  are regarded as the most intelligent of all domestic dog breeds.</p><p>pool or pocket billiards Billiards game played on an oblong table  having six pockets with 15 object balls and a white cue ball. At the begin�  ning of play, the balls are arranged (racked) in a pyramid formation with  its apex on a spot near the foot of the table. The first player breaks the  formation by driving the cue ball into it; to continue play, he or she must  hit a ball into a pocket. In the popular �8-ball� game, the first player (or  team) to sink either the seven solid-coloured balls (numbered 1-7) or the  seven banded (striped) balls (9-15), finishing with the black 8-ball, wins.  In �9-ball,� only the balls numbered 1-9 are used, and they must be sunk  sequentially; the player who sinks the 9-ball wins. Pool probably reached  its present form in England and France by c. 1800; today it is most popu�  lar in North America.</p><p>Poona See Pune</p><p>Poor Law In British history, a body of laws undertaking to provide relief  for the poor, developed in 16th-century England and maintained, with vari�</p><p>ous changes, until after World War II. The original laws provided relief,  including care for the elderly, sick, and infant poor as well as work for the  able-bodied through local parishes. Their scope was curtailed in the 1830s,  when poverty among the able-bodied was considered a moral failing. The  new law provided no relief for the able-bodied poor except employment in  the workhouse, with the object of stimulating workers to seek regular  employment rather than charity. In the 1930s and �40s the Poor Laws were  replaced by a comprehensive system of public welfare services.</p><p>Pop art Art in which commonplace objects (such as comic strips, soup  cans, road signs, and hamburgers) were used as subject matter. The Pop  art movement was largely a British and American cultural phenomenon  of the late 1950s and �60s. Works by such Pop artists as the Americans  Roy Lichtenstein, Andy Warhol, Claes Oldenburg, Tom Wesselman, James  Rosenquist, and Robert Indiana and the Britons David Hockney and Peter  Blake, among others, were characterized by their portrayal of any and all  aspects of popular culture that had a powerful impact on contemporary  life; their iconography�taken from television, comic books, movie maga�  zines, and all forms of advertising�was presented emphatically and  objectively and by means of the precise commercial techniques used by  the media from which the iconography itself was borrowed. Some of the  more striking forms that Pop art took were Lichtenstein�s stylized repro�  ductions of comic strips and Warhol�s meticulously literal paintings and  silk-screen prints of soup-can labels and Marilyn Monroe. Pop art repre�  sented an attempt to return to a more objective, universally acceptable  form of art after the dominance in both the United States and Europe of  the highly personal Abstract Expressionist movement. Its effects�  including its decisive destruction of the boundary between �high� and  �low� art�have continued to be powerfully felt throughout the visual arts  to the present day.</p><p>Pope \po-'pa\ (d. 1692, San Juan Pueblo, New Spain) Tewa Pueblo medi�  cine man. Believing he was guided by tribal ancestral spirits (kachinas),  Pope led an Indian revolt in 1680 against the Spanish invaders in what is  now the southwestern U.S. The rebellion, known as the Pueblo Revolt,  drove the Spanish out of Santa Fe and temporarily restored the old Pueblo  way of life. Pope was accorded great honours, but success made him des�  potic. Although he was eventually deposed, he was reelected Pueblo  leader in 1688.</p><p>pope Ecclesiastical title of the bishop of Rome, head of the Roman Catho�  lic church. In the early church, especially in the 3rd-5th century, it was a  title of affectionate respect for any bishop. It is still used for the Eastern  Orthodox patriarch of Alexandria and for Orthodox priests, but around the  9th century it came to be reserved in the West exclusively for the bishop  of Rome. Catholic doctrine regards the pope as the successor of St. Peter  the Apostle and accords him supreme jurisdiction over the church in mat�  ters of faith and morals, as well as in church discipline and government.  Papal infallibility in matters of doctrine was asserted by the First Vatican  Council in 1870. See also papacy, Roman Catholicism. See tables on fol�  lowing pages.</p><p>Pope, Alexander (b.

A precocious boy  precluded from formal education by  his Roman Catholicism, Pope was  mainly self-educated. A deformity of  the spine and other health problems  limited his growth and physical  activities, leading him to devote him�  self to reading and writing. His first  major work was An Essay on Criti�  cism (1711), a poem on the art of  writing that contains several brilliant  epigrams (e.g., �To err is human, to  forgive, divine�).

ordinar�  ily classed as an antipope, is counted as a pope.</p><p>3 Though elected on March 23, 752, Stephen (II) died two days later before  he could be consecrated and thus is ordinarily not counted. The issue has  made the numbering of subsequent Stephens somewhat irregular.</p><p>^Either Leo VIII or Benedict V may be considered an antipope.</p><p>5 A confusion in the numbering of popes named John after John XIV  (r.983-84) resulted because some 1 lth-cent. historians mistakenly believed  that there had been a pope named John between antipope Boniface VII and  the true John XV (r.985-86). Therefore they mistakenly numbered the real  popes John XV to XIX as John XVI to XX. These popes have since customari�  ly been renumbered XV to XIX, but John XXI and John XXII continue to bear  numbers that they themselves formally adopted on the assumption that there  had indeed been 20 Johns before them. In current numbering, there thus  exists no pope by the name of John XX.</p><p>6 ln the 13th cent, the papal chancery misread the names of the two popes  Marinus as Martin, and as a result of this error Simon de Brie in 1281  assumed the name of Pope Martin IV instead of Martin II. The enumeration  has not been corrected, and thus there exist no Martin II and Martin III.</p><p>epic The Dunciad (1728) and An Epistle to Dr. Arbuthnot (1735). The  philosophical An Essay on Man (1733-34) was intended as part of a larger  work that he never completed.</p><p>Pope, John (b. March 16, 1822, Louisville, Ky., U.S.�d. Sept. 23,  1892, Sandusky, Ohio) U.S. army  officer. A graduate of West Point, he  served in the Mexican War. At the  outbreak of the American Civil War,  he was appointed brigadier general  of volunteers, and he commanded  operations that secured Union navi�  gation of the Mississippi River  almost to Memphis. In 1862 he was  given command of the Army of Vir�  ginia. At the Second Battle of Bull  Run, his forces were defeated.</p><p>Though he tried to blame the rout on  his subordinates, including Fitz-John  Porter, he was relieved of his com�  mand and sent to Minnesota to quell  a Sioux uprising. After the war he  commanded the Department of the  Missouri (1870-83).</p><p>Popish Plot (1678) In English his�  tory, a fictitious but widely believed  rumour that Jesuits planned to assassinate Charles II and replace him with  his brother, the Catholic duke of York (later James II). The rumour was  fabricated by Titus Oates, who gave a sworn deposition of his �evidence�  to a London justice of the peace. When the latter was found murdered, a  panic among the people was followed by accusations and trials, leading  to the execution of about 35 innocent people. When Oates was finally  discredited, the panic subsided.</p><p>poplar Any of at least 35 species and many natural hybrids of trees that  make up the genus Populus (willow family). Poplars grow throughout  northern temperate regions, some even beyond the Arctic Circle. They are  rapid-growing but relatively short-lived. Their leaves flutter in the slight�  est breeze because of their laterally compressed petioles (leafstalks). The  relatively soft wood is used to make cardboard boxes, crates, paper, and  veneer. North America has three groups of native poplars: cottonwoods,  aspens, and balsam poplars.</p><p>poplar, yellow See tulip tree</p><p>Popocatepetl \ 1 po-p3- , ka-t3-,pe-tT\ Volcano, Puebla state, southeast-  central Mexico, west of the city of Puebla. The perpetually snowcapped,</p><p>symmetrical cone reaches 17,930 ft (5,465 m). The first Spanish ascent  is thought to have been made in 1519. After being inactive for more than  50 years, Popocatepetl erupted in 1994, with frequent recurrences in the  years that followed.</p><p>Popol Vuh Vpo-pol-'viiV Mayan document that provides valuable infor�  mation on ancient Maya mythology and culture. It was written between  1554 and 1558 in the Quiche language using Spanish letters. It tells of the  creation of man, the acts of the gods, and the origin and history of the  Quiche people and also gives a chronology of their kings. The book was  discovered early in the 18th century by Francisco Jimenez, a parish priest  in the Guatemalan highlands, who copied out the original, now lost, and  translated it into Spanish.</p><p>popolo \'po-p6-l6\ (Italian: �people�) In the communes (city-states) of  13th-century Italy, a pressure group instituted to protect the interests of  the commoners against the nobility. Until then noblemen had exclusively  controlled the commune governments, and the popolo was the means by  which wealthy merchants sought to extend their power. The popolo in  Florence controlled the government 1250-60 and again after 1282. By  the beginning of the 14th century, its elders formed the supreme execu�  tive of the commune.</p><p>Popper, Sir Karl (Raimund) (b. July 28, 1902, Vienna, Austria�d.  Sept. 17, 1994, Croydon, Greater London, Eng.) Austrian-British philoso�  pher of natural and social science. In The Logic of Scientific Discovery  (1934), he rejected the traditional conception of induction, which held that  a scientific hypothesis may be verified through the accumulation of con�  firming observations, arguing instead that scientific hypotheses can at best  only be falsified. His later works include The Open Society and Its  Enemies (1945), The Poverty of Historicism (1957), and Postscript to the  Logic of Scientific Discovery (3 vol., 1981-82).</p><p>poppy family Family Papaveraceae, containing about 200 species of  mostly herbaceous plants and some woody small trees and shrubs. Most  species of this family, which is outstanding for its many garden ornamen�  tals (largely of the genus Papaver) and for pharmaceutically important  plants, are found in the Northern Hemisphere. All have cup-shaped flow�  ers, a capsule fruit, leaves that are usually deeply cut or divided into leaf�  lets, and coloured sap. Members include the opium poppy and the com, or  Flanders, poppy ( P. rhoeas ), the seeds of which may lie dormant for years.  The latter became a symbol of World War I because it bloomed in fields  that had been disturbed by battle.

The policy of a �united front� against fascism was  announced at the communist Third International (1935); it was to include  not only communists and socialists but also liberals, moderates, and even  conservatives. Popular-front governments were formed in France and  Spain in 1936, but the financial consequences of the reforms undertaken  by the French government, under Leon Blum, proved its undoing, and the  Spanish government was brought down by Francisco Franco in the Span�  ish Civil War.</p><p>Popular Front for the Liberation of Oman (PFLO) orig. Dho-  far Liberation Front Resistance group founded in 1963 by Arab  nationalists and religious conservatives to depose Sultan SaTd ibn Taymur  (r. 1932-70). In 1968 its leadership was taken over by Marxists. In 1970  the sultan was deposed by his son, Qabus ibn SaTd, who softened the  resistance with a combination of military pressure and economic devel�  opment.</p><p>Popular Front for the Liberation of Saguia el Hamra and</p><p>Rio de Oro See Polisario</p><p>popular music Any music intended to be received and appreciated by  ordinary people in a literate, technologically advanced society dominated  by urban culture. Unlike traditional FOLK MUSIC, popular music is written  by known individuals, usually professionals, and does not evolve through  the process of oral transmission. Historically, popular music was any non�  folk form that acquired mass popularity�from the songs of the medieval  minstrels and troubadours to those elements of fine art music originally  intended for a small, elite audience but that became widely popular. After  the Industrial Revolution, true folk music began to disappear, and the  popular music of the Victorian era and the early 20th century was that of  the music hall and vaudeville, with its upper reaches dominated by waltz  music and operettas. In the U.S., minstrel shows performed the composi-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1530 I Popular Party &#x25BA; pork</p><p>tions of songwriters such as Stephen Foster. In the 1890s Tin Pan Alley  emerged as the first popular song-publishing industry, and over the next  half century its lyricism was combined with European operetta in a new  kind of play known as the musical. Beginning with ragtime in the 1890s,  African Americans had begun combining complex African rhythms with  European harmonic structures, a synthesis that would eventually create  jazz. The music audience greatly expanded, partly because of technology.  By 1930, phonograph records had replaced sheet music as the chief source  of music in the home. The microphone enabled more intimate vocal tech�  niques to be commercially adapted. The ability of radio broadcasting to  reach rural communities aided the dissemination of new styles, notably  country music. U.S. popular music achieved international dominance in  the decades after World War II. By the 1950s, the migration of African  Americans to cities in the North had resulted in the cross-fertilization of  elements of blues with the uptempo rhythms of jazz to create rhythm and  blues. Rock and roll, with figures such as Elvis Presley, soon developed as  an amalgam of rhythm and blues with country music and other influences  (see rock music). In the 1960s, British rock groups, including the Beatles,  became internationally influential. Rock quickly attracted the allegiance  of Western teenagers, who replaced young adults as the chief audience  for popular music. From the late 1960s black pop (see Motown) achieved  greater sophistication and a wide audience. The history of pop through  the 1990s was basically that of rock and its variants, including disco, heavy  metal, punk rock, and rap, which spread throughout the world and became  the standard musical idiom for young people in many countries.</p><p>Popular Party (Italy) See Italian Popular Party</p><p>Popular Republican Movement (MRP) French social reform  party. Founded in 1944, the MRP was a strong centre party of the Fourth  Republic and the French expression of Christian Democracy. After winning  about 25% of the vote, it declined in the 1950s, losing strength to both  right and left factions. In 1966 it was merged with other right-centre par�  ties to become the Centre Democrate, which won only 13% of the vote.  By 1968 it had become little more than a political club.</p><p>popular sovereignty Political doctrine that allowed the settlers of  U.S. federal territories to decide whether to enter the Union as free or  slave states. It was applied by Sen. Stephen A. Douglas as a means to reach  a compromise through passage of the Kansas-Nebraska Act. Critics of the  doctrine called it �squatter sovereignty.� The resulting violence between  pro- and antislavery factions (see Bleeding Kansas) showed its failure as a  workable compromise.

They were distinguished and named by Walter Baade  (1893-1960). Population I consists of younger stars, clusters, and asso�  ciations. These occur in and near the arms of the Milky Way Galaxy and  other spiral galaxies and have been detected in irregular galaxies (such  as the Magellanic Clouds). Population I objects are thought to have origi�  nated from interstellar gas that underwent various processes, including  supernova explosions, which enriched their constituent matter with heavier  elements. Population II consists of older (generally 1 billion-15 billion  years old) stars and clusters, presumably formed from interstellar gas  clouds that emerged very early in a galaxy�s history. Consisting almost  entirely of hydrogen and helium, they are found in the galactic halos of  spiral galaxies, in globular clusters, and, in large numbers, in elliptical  galaxies. Astronomers sometimes refer to a Population III as the very first  generation of stars to emerge after the big bang.</p><p>populism Political program or movement that champions the common  person, usually by favourable contrast with an elite. Populism usually  combines elements of the left and right, opposing large business and finan�  cial interests but also frequently being hostile to established socialist and  labour parties. In the U.S. the term was applied to the program of the  Populist movement of the 1890s.</p><p>Populist See Narodnik</p><p>Populist Movement Coalition of U.S. agrarian reformers in the Mid�  west and South in the 1890s. The movement developed from farmers�  alliances formed in the 1880s in reaction to falling crop prices and poor  credit facilities. The leaders organized the Populist, or People�s, Party  (1892), which advocated a variety of measures to help farmers. They also  demanded an increase in the circulating currency (to be achieved by the</p><p>unlimited coinage of silver), a graduated income tax, government own�  ership of the railroads, a tariff for revenue only, and the direct election of  U.S. senators. The party�s presidential candidate in 1892, James B. Weaver  (1833-1912), received more than one million votes. Many state and local  Populist candidates were elected in the Midwest. In 1896 the Populists  joined with the Democratic Party to support the Free Silver Movement and  the unsuccessful presidential candidacy of William Jennings Bryan. The  movement declined thereafter, though some of its causes were later  embraced by the Progressive Party.</p><p>Populonia ancient Pupluna Ancient Roman city, western coast of  central Italy. It was originally Etruscan. Silver and iron ores from the  nearby island of Elba supplied its metal-manufacturing industry. During  the 5th century bc it became wealthy as the first city in Etruria to coin  silver. It was conquered by Romans and suffered during the wars between  Sulla and Marius in the 1st century bc.</p><p>porcelain Vitrified pottery with a white, fine-grained body that is usu�  ally translucent. It was first made in China during the Tang dynasty (618�  907) and in its advanced form during the Yuan dynasty (1279-1368). The  three main types are true (or hard-paste) porcelain, artificial (or soft-paste)  porcelain, and bone china. Attempts by medieval European potters to imi�  tate true porcelain led to the discovery of soft-paste porcelain, which can  be cut with a file. The secret of true porcelain was discovered c. 1707 in  Saxony. Standard English bone china was produced c. 1800 when Josiah  Spode II (1754-1827) added calcined bones to the hard-paste porcelain  formula. Hard-paste porcelain, though strong, chips more readily than  bone china. See also Bow porcelain; Chantilly porcelain; Chelsea porcelain;  Meissen porcelain; Nymphenburg porcelain; Saint-Cloud porcelain; Sevres  porcelain; stoneware.</p><p>porch Roofed structure, usually open at front and sides, projecting from  the face of a building and used to protect an entrance. If colonnaded, it  may be called a portico. A veranda is typically a long porch surrounded  by a railing, often extending along more than one side of a building.  Simple porches were exceedingly common in the domestic architecture  of Britain and the U.S. from the late 18th century. In Gothic cathedrals  the porch was often a small gabled structure projecting from the northern  or southern walls of the nave. See also loggia, narthex.</p><p>porcupine Heavy-bodied, solitary, slow-moving, nocturnal rodent with  quills (modified hairs) along the back, tail, and, on certain crested spe�  cies, the neck and shoulders. The quills are easily detached when touched.  The New World species (four genera in family Erethizontidae) are arbo�  real and have barbed quills; the Old World species (four genera in family  Hystricidae) are terrestrial and have unbarbed quills. The North Ameri�  can porcupine (Erethizon dorsatum ), about 31 in. (80 cm) long with a tail  about 12 in. (30 cm) long and quills about 3 in. (8 cm) long, drives its  powerful tail against an assailant. For food, it favours the tender tissue  beneath tree bark. Crested porcupines, the typical Old World porcupines,  run backward, quills erect, into the enemy. They eat roots, fruit, and other  vegetation. The African crested porcupine, the largest terrestrial rodent in  Europe and Africa, may weigh 60 lb (27 kg) and have quills 14 in. (35  cm) long.</p><p>porgy Vpor-je\ Any of about 100 species (family Sparidae) of generally  shallow-water fishes found through�  out tropical and temperate seas. Por-  gies, sometimes called sea breams,  are typically high-backed, with a  single dorsal fin, a small mouth, and  teeth strong enough to handle fishes  and hard-shelled invertebrates. Most  species do not exceed 1 ft (30 cm)  long, but some may grow to 4 ft (120  cm). The South African mussel-  crackers, popular sport fishes, grow  to 100 lbs (45 kg). In Australia and  Japan, several species of Chrysophrys are important food fish (called  snappers in Australia). The red sea bream inhabits deep European waters.

The word originally signified any work of art or literature  depicting the life of prostitutes. Though pornography is clearly ancient in  origin, its early history is obscure because it was customarily not thought  worthy of transmission or preservation. Nevertheless, in the artwork of  many historic societies, including ancient India, ancient Greece, and  Rome, erotic imagery was commonplace and often appeared in religious  contexts. The Art of Love, by Ovid, is a treatise on seduction and sensual  arousal. The invention of printing led to the production of ambitious works  of pornographic writing intended to entertain as well as to arouse. In  18th-century Europe, pornography became a vehicle for social and politi�  cal protest through its depiction of the misdeeds of royalty and other aris�  tocrats, as well as those of clerics, a traditional target. The development  of photography and motion pictures in the 19th and 20th centuries con�  tributed greatly to the proliferation of pornography, as did the advent of  the Internet in the late 20th century. During the 20th century, restrictions  on pornography were relaxed throughout much of Europe and North  America, though regulations remained strict in Asia, the Middle East, and  Africa. Child pornography is almost universally prohibited.</p><p>porphyrin Vpor-fo-ronX Any of a class of biologically important het�  erocyclic compounds of a characteristic chemical structure that includes  four pyrrole groups (five-membered organic rings each containing a nitro�  gen atom) linked by additional carbon atoms to form a large flat ring. As  biological pigments, they and closely related molecules are responsible for  many of the vivid colours in living organisms, where they often occur  combined with metal ions and various substituents as coordination com�  plexes (see compound). These include the magnesium-containing chloro�  phylls and the iron-containing heme group, a constituent (along with  protein) of, e.g., hemoglobin, the cytochromes, and the enzyme catalase. In  medicine, porphyrins are used in conjunction with light, often a laser  beam, to induce reactions in the body against cancer and other diseases.</p><p>porphyry copper deposit \'por-f9-re\ A large body of igneous rock,  having distinct crystals in a relatively fine-grained base, that contains chal-  copyrite and other sulfide minerals. These deposits contain vast amounts of  ore that averages a fraction of 1% copper by weight; although low-grade,  the deposits are important because they can be worked on a large scale at  low cost. Large porphyry copper deposits are worked in the southwestern  U.S. (where molybdenum may be produced as a by-product), the Solomon  Islands, Canada, Peru, Chile, Mexico, and elsewhere.</p><p>porpoise Any toothed whale in the family Phocoenidae (or, by some  authorities, part of the dolphin family Delphinidae). The four species  (genus Phocoena) of the common, or harbour, porpoise are primarily fish  eaters that travel in pairs or large groups. They are gray or black above  and white below. The shy P. phocoena, found throughout the Northern  Hemisphere, rarely leaps. The other species of Phocoena are found along  Californian and South American coasts. The active, gregarious Dali por�  poise ( Phocoenoides dalli ) of the North Pacific and the True porpoise (P.  truei) of Japan often swim with ships, usually in groups of 2 to 20. Both  eat cephalopods and fishes and are black with a large white patch on each  side. The black finless porpoise ( Neomeris phocoenoides ), a small, slow  animal, inhabits the Pacific and Indian oceans. At most 7 ft (2 m) long,  porpoises are shorter and chubbier than dolphins and have a blunt snout.  Like the dolphins, they are known for their high intelligence.</p><p>port Input/output conduit for personal computers. The serial port was cre�  ated as an interface between data terminal equipment and data-  communications equipment. It processes data sequentially, as a series of  bits, and is used to connect equipment (e.g., a modem or mouse) to the com�  puter. The parallel port processes several data bits in parallel and is used  to connect peripherals such as computer printers and optical scanners to  the computer. The parallel port is faster, but the serial port is cheaper and  requires less power. See also USB.</p><p>port Sweet, fortified wine of rich taste and aroma made in Portugal. The  name derives from Porto, the town where it is traditionally aged and  bottled. Most port is red, but lesser amounts of tawny and white are pro�  duced.

As a student at Yale University he composed  about 300 songs, including �Bulldog�; he went on to study law and then  music at Harvard. He made his Broadway debut with the musical com�  edy See America First (1916). In 1917 he went to France and became an  itinerant playboy; though rather openly homosexual, he married a wealthy  divorcee. He wrote songs for the Broadway success Paris (1928), and  this led to a series of his own hit musicals, including Anything Goes  (1934), Red, Hot and Blue (1934), Kiss Me, Kate (1948), Can-Can (1953),  and Silk Stockings (1955). Porter also worked on a number of films, such  as High Society (1956).

In the War of 1812 he commanded the Essex, the first U.S.  warship to operate in the Pacific Ocean; he captured several British whal�  ing vessels and took possession of Nuku Hiva, the largest of the Marquesas  Islands (1813). He was blockaded by British frigates in Valparaiso, Chile,  where he surrendered (1814). He served on the board of naval commis�  sioners (1815-23) and commanded a squadron to suppress piracy in the  West Indies (1823-25). For unauthorized action against Spanish authori�  ties in Puerto Rico, he was court-martialed and suspended from duty.

Founded in 1752 and named after Portsmouth, Eng., it was occupied by  both British and American troops during the American Revolution. It was  incorporated as a city in 1858. During the American Civil War the U.S.  Navy Yard was evacuated by Union troops, allowing Southern troops  access to stores of equipment; Portsmouth was recaptured in 1862. It is  part of the U.S. military complex at Hampton Roads. Shipbuilding and  ship repair are the main economic activities, augmented by various manu�  factures.</p><p>Portsmouth, Treaty of (1905) Peace settlement that ended the Russo-  Japanese War.

Language: Portu�  guese (official). Religion: Christianity  (predominantly Roman Catholic). Cur�  rency: euro. Administratively, the Atlantic  islands of the Azores and Madeira are part  of Portugal. Portugal is divided roughly in half by the Tagus River; the  highlands rise mostly north of the Tagus and stretch northeast into Spain.  Portugal has an industrialized economy in which both public and private  sectors participate. Major industries were nationalized after a military  coup in 1974, but many were returned to the private sector beginning in  the late 1980s. Although motor vehicle manufacture is significant, light  industries predominate; important products include textiles and clothing,  paper and wood products, and chemicals. Portugal is a republic with a  unicameral legislature; the chief of state is the president, and the head of  government is the prime minister. In the 1st millennium bc, Celtic peoples  settled the Iberian Peninsula. They were conquered c. 140 bc by the  Romans, who ruled until the 5th century ad, when the area was invaded  by Germanic tribes. A Muslim invasion in 711 left only the northern part</p><p>PORTUGAL</p><p>of Portugal in Christian hands. In 1179 it became the kingdom of Portu�  gal and expanded as it reconquered the Muslim-held sectors. The bound�  aries of modern continental Portugal were completed under King Afonso  III (reigned 1248-79). From 1580 to 1640 Portugal was united with Spain.  In the 15th and 16th centuries the monarchy encouraged exploration that  took Portuguese navigators to Africa, India, Indonesia, China, the Middle  East, and South America. Although Portugal established several colonies,  they achieved independence over the years (see Brazil; Goa; Cape Verde;  East Timor; Angola; Guinea-Bissau; Mozambique; Macau). Antonio de  Oliveira Salazar ruled Portugal as a dictator from 1932 to 1968. The coun�  try�s dictatorship was overthrown in the April 25, 1974, Revolution of the  Carnations. A new constitution was adopted in 1976, and civilian rule  resumed. Portugal was a charter member of NATO and is a member of  the European Union (EU). In 1999 the government adopted the euro as the  country�s official monetary unit and returned Macau, its last overseas ter�  ritory, to Chinese rule.</p><p>Portuguese East Africa See Mozambique  Portuguese Guinea See Guinea-Bissau</p><p>Portuguese language Romance language spoken by about 170 mil�  lion people in Portugal, Brazil, and other former Portuguese colonies. The  first literary works in Portuguese date from the 13th�14th century. Stan�  dard Portuguese is based on the dialect of Lisbon. Dialectal variation in  Portugal is limited, but the differences between Brazilian and European  Portuguese are more extensive, including changes in phonology, verb  conjugation, and syntax. The four major dialect groups are Northern (Gali�  cian, spoken in northwestern Spain), Central, Southern (including the  Lisbon dialect), and Insular (including Brazilian and Madeiran) Portu�  guese.</p><p>Portuguese man-of-war Any of various floating, warm-water  marine cnidarians (genus Physalia, class Hydrozoa) found worldwide but  mostly in the Gulf Stream and the Indian and Pacific oceans. The medusa-  form body consists of a translucent, jellylike, gas-filled float, which may  be 3-12 in. (9-30 cm) long. Polyps beneath the float bear hanging ten�  tacles up to 165 ft (50 m) long. Nematocysts on some polyps paralyze  fish and other prey. Other polyps then attach to, spread over, and digest  the victim. A third type of polyp is involved in reproduction. The painful  sting of Physalia can cause fever, shock, or disruption of heart and lung  function.</p><p>Portuguese West Africa See Angola</p><p>Poseidon \po-'sI-d3n\ Greek god of water and the sea, son of Cronus  and Rhea.

More narrowly, the term  designates the philosophy of Auguste Comte, who held that human thought  had passed inevitably through a theological stage into a metaphysical  stage and was passing into a positive, or scientific, stage. Believing that  the religious impulse would survive the decay of revealed religion, he  projected a worship of mankind, with churches, calendar, and hierarchy.</p><p>Poseidon, marble statue from Melos,  2nd century bc; in the National  Archaeological Museum, Athens.</p><p>AUNARI-ART RESOURCE/EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1534 I positron &#x25BA; postmodernism</p><p>positron Vpa-z3-,tran\ Subatomic particle having the same mass as an  electron but with an electric charge of+1 (an electron has a charge of -1).

At  the turn of the century her straitened  circumstances compelled her to  begin writing light fiction and maga�  zine articles. At her publisher�s sug�  gestion, she undertook her major  work, Etiquette: The Blue Book of  Social Usage (originally Etiquette in  Society, in Business, in Politics and  at Home), in 1922; unlike earlier  writers on the subject, she directed  her commonsense views to the ordi�  nary person of moderate means. The  book appeared in 10 editions and 90  printings in her lifetime. The out�  pouring of letters it provoked  inspired her newspaper column,  which became widely syndicated.</p><p>post-and-beam system In</p><p>building construction, a system in which two upright members, the posts,  hold up a third member, the beam, laid horizontally across their top sur�  faces. In Britain it is called post-and-lintel system, but in the U.S. �lin�  tel� is usually reserved for a short beam that spans a window or door  opening. The post and beam formed the basis of architecture from pre�  historic to Roman times, and is illustrated by such ancient structures as</p><p>Stonehenge. All structural openings evolved from this system, which is  seen in pure form only in colonnades and in framed structures, the posts  of doors, windows, ceilings, and roofs usually being hidden in walls. The  beam must bear loads that rest on it as well as its own load without  deforming or breaking. Post-and-beam construction has largely been sup�  planted by the modern steel frame.</p><p>Post-Impressionism Movement in Western painting that represented  both an extension of Impressionism and a rejection of its limitations. The  term was coined by Roger Fry for the works of Paul Cezanne, Georges  Seurat, Vincent van Gogh, Paul Gauguin, Henri de Toulouse-Lautrec, and  others. Most of these painters first pursued Impressionism, a style based,  in its strictest sense, on the objective recording of nature in terms of the  fugitive effects of colour and light. The Post-Impressionists rejected this  aim in favour of more ambitious expression, admitting their debt, how�  ever, to the pure, brilliant colours of Impressionism, its freedom from tra�  ditional subject matter, and its technique of defining form with short  brushstrokes of broken colour. Each painter in the movement pursued  unique, personal subject matter and, while sharing stylistic goals with the  other Post-Impressionists, had a personal form of expression. For  example, Cezanne abandoned the Impressionists� virtuoso depiction of  evanescent light effects in order to pursue his preoccupation with the  underlying structures of natural forms and the problem of unifying sur�  face patterns with spatial depth. Both Gauguin and van Gogh rejected the  indifferent objectivity of Impressionism in favour of a more personal,  spiritual expression. The Post-Impressionists often exhibited together but,  unlike the Impressionists, who were a close-knit and convivial group, they  painted mainly alone. In general, Post-Impressionism led away from a  naturalistic approach and toward the two major movements of early 20th-  century art that followed it: Cubism and Fauvism. See also Neo-Impressionism.</p><p>post-traumatic stress disorder (PTSD) Psychological reaction  occurring after a highly stressful event and typically characterized by  flashbacks, recurrent nightmares, and avoidance of reminders of the event;  depression and anxiety are often present. Traumatic events that can lead to  PTSD include automobile accidents, rape or assault, military combat, tor�  ture, and such natural disasters as floods, fires, or earthquakes. Long-term  effects can include marital and family problems, difficulties at work, and  abuse of alcohol and other drugs. Antidepressant medication and psycho�  therapy, including group therapy, are used in treating the disorder.</p><p>postal system System that allows persons to send letters, parcels, or  packages to addressees in the same country or abroad. Postal systems are  usually government-run and paid for by a combination of user charges  and government subsidies. There are early references to postal services  in Egypt c. 2000 bc and in Zhou-dynasty China c. 1000 bc. The Roman  Empire developed various centralized methods of relaying messages. In  the Middle Ages there were no centralized postal services. Private postal  systems developed with the rise of nation-states during the Renaissance;  subsequently, postal services became government monopolies. Charges  based on weight rather than distance and the use of prepaid stamps were  first proposed in 1837. The General Postal Union (1875; later Universal  Postal Union) improved international mail delivery by allowing member  countries to retain the postage they collected on outgoing international  mail and requiring them to treat incoming international mail as they did  domestic mail. Airmail and automated mail handling were developed in  the 20th century. See also e-mail.</p><p>poster Eye-catching printed paper announcement or advertisement that is  exhibited to promote a product, event, or idea. Posters were popularized by  the mid-19th-century invention of lithography, which allowed coloured  posters to be produced cheaply and easily. Henri de Toulouse-Lautrec was  noted for his poster art, which often advertised Parisian cabaret performers.  Poster art flourished with the rise of the Art Nouveau style, as seen in the  work of Alphonse Mucha. During World War I posters were used for recruit�  ing and propaganda, and the industrial boom of the early 20th century gave  rise to advertising posters for every conceivable product and event. The  later rise of film and television advertising led to an eclipse in poster art.</p><p>postmodernism Any of several artistic movements since about the  1960s that have challenged the philosophy and practices of modern arts or  literature. In literature this has amounted to a reaction against an ordered  view of the world and therefore against fixed ideas about the form and  meaning of texts. In its reaction against Modernist ideals (see Modernism)  such as autotelic art and the original masterpiece, postmodern writing and  art emphasize devices such as pastiche and parody and the stylized tech-</p><p>Emily Post.</p><p>BROWN BROTHERS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>postmortem &#x25BA; Potok I 1535</p><p>nique of the antinovel and magic realism. Postmodernism has also led to a  proliferation of critical theories, most notably deconstruction and its off�  shoots, and the breaking down of the distinction between �high� and �low�  culture.</p><p>postmortem See autopsy</p><p>poststructuralism Movement in literary criticism and philosophy  begun in France in the late 1960s. Drawing upon the linguistic theories  of Ferdinand de Saussure, the anthropology of Claude Levi-Strauss (see struc�  turalism), and the deconstructionist theories of Jacques Derrida (see decon�  struction), it held that language is not a transparent medium that connects  one directly with a �truth� or �reality� outside it but rather a structure or  code, whose parts derive their meaning from their contrast with one  another and not from any connection with an outside world. Writers asso�  ciated with the movement include Roland Barthes, Jacques Lacan, Julia  Kristeva, and Michel Foucault.</p><p>Potala Palace Vpo-to-loV Religious and administrative complex, near  Lhasa, Tibet, China. It covers 5 sq mi (13 sq km) atop a hill 425 ft (130  m) above the Lhasa River valley. Potrang Karpo (the White Palace, com�  pleted 1648) once served as the seat of the Tibetan government and the  main residence of the Daai Lama; from the mid-18th century it was used  as a winter palace. Potrang Marpo (the Red Palace, 1694) houses several  chapels, sacred statues, and the tombs of eight Dalai Lamas; it remains a  major pilgrimage site for Tibetan Buddhists. The complex, which has a  total of 1,000 rooms, was declared a world heritage site in 1994.</p><p>potash \'pat-,ash\ Name used for various inorganic compounds of potas�  sium, chiefly the carbonate (K 2 C0 3 ), a white crystalline material formerly  obtained from wood ashes. They are used to make special types of glass,  potassium silicate (a dehydrating agent), pigments, printing inks, and soft  soaps; for washing raw wool; and as a lab reagent and general-purpose  food additive. Potassium hydroxide is frequently called caustic potash,  and in the fertilizer industry, potassium oxide is called potash.</p><p>potash mica See muscovite</p><p>potassium Chemical element, one of the alkali metals, chemical symbol  K, atomic number 19. It is a soft, silvery white metal, not found free in  nature and rarely used as the metal (except as a chemical reagent) because  of its extreme reactivity. Potassium is essential for life and is present in  all soils. Potassium ions (K + ) and sodium ions act at cell membranes in  electrochemical impulse transmission and in transport. Potassium in com�  pounds has valence 1. The chloride is used as a fertilizer and a raw mate�  rial for producing other compounds, and the hydroxide for making liquid  soaps and detergents and in preparing various salts. The iodide is added  to table salt to protect against iodine deficiency. The nitrate is also called  saltpetre, and the carbonate is called potash.</p><p>potassium-argon dating Method for determining the age of igne�  ous rocks based on the amount of argon-40 in the rock. Radioactive  potassium-40 decays to argon-40 with a half-life of about 1.3 billion years,  making this method useful for dating rocks that are billions of years old.  A more sophisticated method, called argon-argon dating, provides a more  accurate estimate of the original potassium-40 content by means of the  ratio of argon-40 to argon-39 in the rock, thus yielding a more accurate  age determination.

More than  20 sequels followed, featuring such</p><p>Beatrix Potter, 1913</p><p>PICTORIAL PARADE /LONDON DAILY EXPRESS, REPRODUCED  BY PERMISSION OF FREDERICK WARNE &amp; CO.</p><p>original characters as Jeremy Fisher, Squirrel Nutkin, Jemima Puddle-  Duck, and Mrs. Tiggy-Winkle.</p><p>Potter, Dennis (Christopher George) (b. May 17, 1935, Berry  Hill, Gloucestershire, Eng.�d. June 7, 1994, Ross-on-Wye, Hereford�  shire) British dramatist. Educated at Oxford, he thereafter devoted him�  self to writing, especially of television plays. His innovative serial Pennies  from Heaven (1978) combined fantasy sequences and musical interludes  in which actors lip-synched to old recordings of period songs. His best-  known teleplay, the eight-part The Singing Detective (1986), an autobio�  graphical account of his crippling bouts of psoriatic arthropathy, combined  humour, pathos, and fantastic musical numbers. His other teleplays  include the allegedly sacrilegious Brimstone and Treacle (1976, televised  1987) and Lipstick on Your Collar (1993). His movie screenplays include  Gorky Park (1983) and Dreamchild (1985).</p><p>pottery One of the oldest and most widespread of the decorative arts,  consisting of objects (mostly useful ones, such as vessels, plates, and  bowls) made of clay and hardened with heat. Earthenware is the oldest  and simplest form; stoneware is fired at a high temperature to cause it to  vitrify and harden; and porcelain is a fine, generally translucent form of  pottery. The Chinese began their sophisticated production of pottery in  the Neolithic period and produced porcelain as early as the 7th century  ad. Chinese porcelain, or �china,� was widely exported to Europe and  had a profound influence on European manufacturers and on taste. Clas�  sical Greece and Islamic cultures are also known for their artistic and  technical innovations in pottery.</p><p>Poujade \pu-'zhad\, Pierre (-Marie) (b. Dec. 1, 1920, Saint-Cere,  France�d. Aug. 27, 2003, La Bastide-l�Eveque) French political leader.  The owner of a bookstore in Saint-Cere, in 1953 he organized a local  shopkeepers� strike to protest high taxation. Expanding his activities to  other towns, he enrolled 800,000 members in his Union for the Defense  of Tradesmen and Artisans. His right-wing movement, known as Pou-  jadism, attracted discontented farmers and merchants; in 1956 it won 52  seats in the National Assembly. Poujade�s influence soon waned, but in  the 1970s he founded an organization for nonunion workers.</p><p>Poulenc Vpu-.laqkV Francis (Jean Marcel) (b. Jan. 7, 1899, Paris,  Fr.�d. Jan. 30, 1963, Paris) French composer. In his teens he studied  piano with Ricardo Vines (1875-1943). Influenced by Erik Satie, Poulenc  and five other like-minded young composers became known as Les Six.  Poulenc wrote piano compositions, orchestral music, and chamber music,  but he is best known for his vocal music, including many admired songs,  the operas The Breasts of Tiresias (1944), Dialogues of the Carmelites  (1956), and La voix humaine (1958), and such sacred choral works as  Mass in G Major (1937), the Stabat Mater (1950), and the Gloria (1959),  reflecting his devout Catholicism.</p><p>poultry farming Raising birds commercially or domestically for meat,  eggs, and feathers. Chickens, ducks, turkeys, and geese are the birds of  primary commercial importance. Guinea fowl and squabs are chiefly of  local interest. Though chickens have been domesticated for at least 4,000  years, their meat and eggs have been mass-production commodities only  since c. 1800.</p><p>pound Unit of weight in the avoirdupois system, the traditional Euro�  pean system of weight (incorporated into the British Imperial system and  the U.S. system of weights and measures), equal to 16 oz, 7,000 grains,  or 0.4536 kg. It is also a unit of weight in the troy and apothecaries� sys�  tems (two other traditional systems of weight), equal to 12 troy or apoth�  ecaries� oz, 5,760 grains, or 0.37 kg. Its Roman ancestor, the libra, is the  source of the abbreviation lb. The troy pound is used for precious met�  als, the apothecaries� pound for drugs. The British monetary pound is  linked historically with the minting of silver coins (sterlings). Large pay�  ments were reckoned in �pounds of sterlings,� later shortened to �pounds  sterling.� See also gram; International System of Units; measurement; metric  system; ounce.</p><p>Pound, Ezra (Loomis) (b. Oct. 30,1885, Hailey, Idaho, U.S.�d. Nov.  1, 1972, Venice, Italy) U.S. poet and critic. Pound attended Hamilton  College and the University of Pennsylvania, where he studied various  languages. In 1908 he sailed for Europe, where he would spend most of  his life. He soon became a leader of Imagism and a dominant influence in  Anglo-American verse, helping promote writers such as William Butler  Yeats, James Joyce, Hilda Doolittle, Ernest Hemingway, Robert Frost, D.H.  Lawrence, and T.S. Eliot, whose The Waste Land he brilliantly edited.

He also  began publishing The Cantos, an attempt at an epic sequence of poems,  which would remain his major poetic occupation throughout his life. With  the onset of the Great Depression, he increasingly pursued his interest in  history and economics, became obsessed with monetary reform, and  declared his admiration for Benito Mussolini. In World War II he made  pro-fascist radio broadcasts; detained by U.S. forces for treason in 1945,  he was initially held at Pisa; The Pisan Cantos (1948, Bollingen Prize),  written there, are notably moving. He was subsequently held in an Ameri�  can mental hospital until 1958, when he returned to Italy. The Cantos  (1970) collects his 117 completed cantos.</p><p>Pound, Roscoe (b. Oct. 27, 1870, Lincoln, Neb., U.S.�d. July 1,  1964, Cambridge, Mass.) U.S. legal  educator and botanist. After studying  botany at the University of Nebraska  and law at Harvard University  (1889-90), he was admitted to the  Nebraska bar, and he practiced law  while also teaching at the state uni�  versity (1890-1903). At the Univer�  sity of Nebraska he directed the state  botanical survey (1892-1903) and  discovered a rare fungus (. Rosco-  poundia). He later taught at several  law schools, most notably Harvard  (1910-37), where he also served as  dean (1916-36), instituting many  reforms. He was perhaps the chief  U.S. advocate of sociological juris�  prudence, which holds that statutes  and court decisions are affected by  social conditions; his ideas appar�  ently influenced the New Deal pro�  grams of Pres. Franklin D. Roosevelt. After World War II he helped  reorganize the judicial system of Taiwan.</p><p>Poussin \pii-'sa n \, Nicolas (b. 1594, Villers, France�d. Nov. 19,1665,  Rome, Papal States) French painter. Except for two years as court painter  to Louis XIII, he spent his entire career in Rome, where he became an  admirer of ancient Roman civilization. In early works, he depicted themes  from Classical mythology in a painterly style reminiscent of such Vene�  tian masters as Titian. Turning to Raphael for inspiration, he began in the  mid 1630s to develop a style marked by Classical clarity and monumen-  tality. His late masterworks, such as Holy Family on the Steps (1648),  employ a style calculated to express virtue and rectitude, featuring only  a few figures painted in harsh colours against a severe background. In his  landscapes, such as Landscape with Polyphemus (1649), the disorder of  nature is reduced to the order of geometry. His austere and highly ordered  compositions influenced generations of French painters, including  Jacques-Louis David, J.-A.-D. Ingres, and Paul Cezanne.</p><p>powder metallurgy Fabrication of metal objects from a powder  rather than casting from molten metal or forging at softening tempera�  tures. In some cases the powder method is more economical, as in mak�  ing metal parts such as gears for small machines, in which casting would  involve considerable scrap loss. In other cases, melting is impractical  (e.g., because the melting point of the metal is too high). Powder metal�  lurgy is also used to produce a porous product that will allow a liquid or  gas to pass through it.

In 1937 he succeeded  his father as pastor of the Abyssinian Baptist Church in Harlem, New York  City, and built its membership to 13,000. Elected to the New York City  Council in 1941, he became the first African American to serve on that  body. In the U.S. House of Representatives (1945-67, 1969-71), he spon�  sored much social-welfare legislation, including a minimum wage act,  antipoverty acts, and bills providing federal aid to education. Known for  his flamboyance and his lack of concern for House decorum, he was the  target of a libel suit and was investigated for financial misconduct. In 1967  the House voted to exclude him, but the U.S. Supreme Court later ruled  that the House�s action was unconstitutional.</p><p>Powell Vpo-ol, 'pau(-9)l\, Anthony (Dymoke) (b.

His style became  the predominant approach for post-swing era pianists: he did away with  most accepted functions of the left hand, reducing it to playing brief, syn�  copated chords supporting long melody lines by the right hand. He moved  to Paris in 1959 and returned to the U.S. in 1964. His career was inter�  rupted several times due to nervous breakdowns thought to derive from  head injuries sustained in a racially motivated attack in 1945.</p><p>Powell, Colin (Luther) (b.

After holding various posts in the Pentagon and elsewhere, he was  appointed senior military assistant to the secretary of defense in 1983. In  1987 he joined the staff of the National Security Council; in that same  year Pres. Ronald Reagan appointed him assistant to the president for  national security affairs. In 1989 Powell was promoted to four-star gen�  eral and, appointed by Pres. George Bush, became the first African Ameri�  can to serve as chairman of the Joint Chiefs of Staff.

A  given amount of work can be done by a low-powered motor in a long  time or by a high-powered motor in a short time. Units of power are those  of work (or energy) per unit time, such as foot-pounds per minute, joules  per second (called watts), or ergs per second. Power can also be expressed  as the product of the force ( F) applied to move an object and the speed  (v) of the object in the direction of the force: P = Fv.

Powhatan languages belong to the Algonquian language family. They  once occupied most of Tidewater Virginia and the eastern shore of Chesa�  peake Bay. The confederacy was named for its powerful chief, Powhatan,  to whom the tribes provided military support and paid taxes in the form  of goods. Many of the villages, consisting of long dwellings covered with  bark or reed mats, were palisaded. Powhatan women cultivated corn,  beans, and squash; the men hunted and waged war, chiefly against the  Iroquois. The intermittent hostilities with the English settlers, often called  the Powhatan War (1622-44), ended with the breaking of the confederacy.</p><p>powwow American Indian ceremony or gathering of various kinds.

Notable contributors include Yi Ik (1681�  1763), who wrote on land reform and the abolition of class barriers, and  Pak Chi-won (1737-1805), who advocated the development of commerce  and technology. The school contributed to the wave of modernization that  occurred after the introduction of Western culture into Korea in the late  19th century.</p><p>practical reason Rational capacity by which (rational) agents guide  their conduct. In Immanuel Kant�s moral philosophy, it is defined as the  capacity of a rational being to act according to principles (i.e., according  to the conception of laws). Unlike the ethical intuitionists (see intuition-  ism), Kant never held that practical reason intuits the rightness of particu�  lar actions or moral principles. For him, practical reason was basically  formal rather than material, a framework of formative principles rather  than a source of specific rules. This is why he put such stress on his first  formulation of the categorical imperative. Lacking any insight into the  moral realm, humans can only ask themselves if what they are proposing  to do has the formal character of law, namely, the character of being the  same for all persons similarly circumstanced.</p><p>Prado \'pra-do\ Museum Spain�s national art museum, housing the  world�s greatest collection of Spanish painting as well as other European  works. Founded in Madrid in 1818 by Ferdinand VII, it was opened to the  public in 1819 as the Royal Museum of Painting. Its holdings were formed  over three centuries from the various royal collections of the Habsburg  and Bourbon monarchs in Spain. In 1868 it became the National Museum  of the Prado after the exile of Isabella II. In 1872 it acquired many notable  paintings formerly owned by Spanish convents and monasteries. It owns  the outstanding collections of the works of El Greco, Diego Velazquez, and  Francisco de Goya and numerous works by other Spanish masters such as  Jose de Ribera and Francisco Zurbaran.

It was a major centre for the cult of the goddess  Fortuna, whose sanctuary and temple oracle were surrounded by an  immense complex of buildings. It became a favourite summer resort of  wealthy Romans, including Augustus, Hadrian, and Puny the Younger. The  modern town is the birthplace of composer Giovanni Pierluigi da Pal�  estrina.</p><p>praetor Vpre-torN In ancient Rome, a judicial officer who had broad  authority in cases of equity, was responsible for producing public games,  and, in the absence of a consul, exercised extensive authority in the gov�  ernment. After a one-year term, a praetor typically went on to govern a  province. Originally only a patrician magistrate could be a praetor, but  from c. 337 bc, the position was also open to plebeians. The number of  praetors increased to eight by the 1st century bc, two for civil matters and  six for specific courts. It continued to vary under different government  leaders and emperors; by the late empire, only the city praetor for public  games remained.</p><p>Praetorian \pre-'tor-e-3n\ Guard (Latin, cohors praetoria) House�  hold troops of the Roman emperors. In the 2nd century bc they were  bodyguards for Roman generals, their name taken from the general�s tent  ( praetorium ). During the civil wars military leaders had personal body�  guards, but in 27 bc Augustus created a permanent corps to guard the  emperor and stationed its members around Rome. In ad 23, with Sejanus  as commander, they gained political influence; from then on, they usually  had an important voice in the appointment of emperors. They were respon�</p><p>sible for the accession of Claudius (41), the disorders of 68-69, the lynch�  ing of Domitian�s murderers (97), and the murder of Elagabalus (222).  Constantine I disbanded the Praetorian Guard in 312.</p><p>Pragmatic Sanction (1713) Decree by Emperor Charles VI requiring  the undivided descent of his Habsburg domains. It stipulated that his heri�  tage go to his eldest son or, in the absence of a son, to his eldest daugh�  ter. It became law in 1720 within the Habsburg states, and much of  Charles�s later reign was directed toward securing acceptance of the sanc�  tion from the other European powers. Since his son died soon after birth  (1716), his daughter Maria Theresa became his heir. On Charles�s death  (1740), the sanction was contested by Prussia and Bavaria, which led to  the War of the Austrian Succession.</p><p>Pragmatic Sanction of Bourges VbUrzh\ (July 7, 1438) Decree  issued by King Charles VII of France after the Council of Basel, confirm�  ing the supremacy of a council over the pope. The decree also confirmed  the Council�s assertion of the �liberties� of the Gallican Church, restrict�  ing the rights of the pope and in many cases making his jurisdiction sub�  ject to the king�s. Revoked by Louis XI in 1461, the Pragmatic Sanction  was reasserted periodically until the 16th century.</p><p>pragmatics In linguistics and philosophy, the study of the use of natu�  ral language in communication; more generally, the study of the relations  between languages and their users. It is sometimes defined in contrast with  linguistic semantics, which can be described as the study of the rule sys�  tems that determine the literal meanings of linguistic expressions. Prag�  matics is then the study of how both literal and nonliteral aspects of  communicated linguistic meaning are determined by principles that refer  to the physical or social context (broadly construed) in which language  is used. Among these aspects are conversational and conventional �impli-  catures� (e.g., �John has three sons� conversationally implicates that John  has no more than three sons; �He was poor but honest� conventionally  implicates an unspecified contrast between poverty and honesty). Other  aspects include metaphor and other tropes and speech acts.</p><p>pragmatism Philosophical movement first given systematic expres�  sion by Charles Sanders Peirce and William James and later taken up and  transformed by John Dewey. Pragmatists emphasize the practical function  of knowledge as an instrument for adapting to reality and controlling it.  Pragmatism agrees with empiricism in its emphasis on the priority of expe�  rience over A priori reasoning. Whereas truth had traditionally been  explained in terms of correspondence with reality or in terms of coher�  ence (see coherentism), pragmatism holds that truth is to be found in the  process of verification. Pragmatists interpret ideas as instruments and  plans of action rather than as images of reality; more specifically, they are  suggestions and anticipations of possible conduct, hypotheses or forecasts  of what will result from a given action, or ways of organizing behaviour.

Situated on both sides of the Vltava River, the site was settled  as early as the 9th century ad. By the 14th century it was one of Europe�s  leading cultural and trade centres. It was the focal point of opposition to  the Habsburgs in the early 17th century (see Defenestration of Prague).  The treaty ending the Austro-Prussian War was signed there in 1866. It  became the capital of an independent Czechoslovakia in 1918. Prague was  occupied by Germany during World War II and by the U.S.S.R. and other  Warsaw Pact military forces in 1968 (see Prague Spring). In 1989 it was  the centre of a movement that led to the peaceful overthrow of the com�  munist government. Prague is the country�s major economic and cultural  centre, famous for its music, literature, and architecture.</p><p>Prague, Defenestration of (May 23, 1618) Incident of Bohemian  resistance to Habsburg authority. In 1617 Catholic officials in Bohemia  closed Protestant chapels in violation of the religious-liberty guarantee of  1609. At an assembly called by the Protestants, the imperial regents were  found guilty of violating the guarantee and were thrown from the win�  dows of the council room of Prague Castle. Though the victims were not  seriously hurt, the incident sparked the Bohemian revolt against Emperor  Ferdinand II and led to the Thirty Years' War.</p><p>Prague Spring (1968) Brief period of liberalization in Czechoslova�  kia under Alexander Dubcek. In April 1968 he instituted agricultural and  industrial reforms, a revised constitution to guarantee civil rights,  autonomy for Slovakia, and democratization of the government and the  Communist Party. By June, many Czechs were calling for more rapid</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1540 I Praia &#x25BA; Pratt</p><p>progress toward real democracy. Although Dubcek believed he could con�  trol the situation, the Soviet Union and the Warsaw Pact countries,  alarmed by the threat of a social-democratic Czechoslovakia, invaded the  country in August, deposed Dubcek, and gradually restored control by  reinstalling hard-line communists as leaders.</p><p>Praia Vpri-9\ City (pop., 2000: 94,757), port, and capital of Cape Verde.  It is located on the southern shore of Sao Tiago (Santiago) Island, in the  Atlantic Ocean, about 400 mi (640 km) off the western African bulge. It  ships agricultural products, including bananas, coffee, and sugarcane, and  it is a submarine cable station.</p><p>prairie Level or rolling grassland, especially that found in central North  America. Decreasing amounts of rainfall, from 40 in. (100 cm) at the for�  ested eastern edge to less than 12 in. (30 cm) at the desertlike western  edge, affect the species composition of the prairie grassland. The vegeta�  tion is composed primarily of perennial grasses, with many species of  flowering plants of the pea and composite families. The three main types  of prairie are the tallgrass prairie; midgrass, or mixed-grass, prairie; and  shortgrass prairie, or shortgrass plains. Coastal prairie, Pacific or Califor�  nia prairie, Palouse prairie, and desert plains grassland are covered pri�  marily with combinations of mixed-grass and shortgrass species.</p><p>prairie chicken Either of two species of North American grouse (genus  Tympanuchus) noted for lek displays (group courtship displays). The  greater prairie chicken is about 18 in. (45 cm) long and may weigh almost  2 lbs (1 kg). Its brown plumage is strongly barred below, and it has a  short, rounded, dark tail. It occurs locally from Saskatchewan to coastal  Texas and Louisiana; northernmost birds are somewhat migratory. The  eastern subspecies, the heath hen, is extinct. The lesser prairie chicken,  smaller and paler, inhabits the arid western central Great Plains. The  sharp-tailed grouse ( Pedioecetes ) is locally called prairie chicken.</p><p>prairie dog Any of five species (genus Cynomys) of short-legged, ter�  restrial squirrels, named for their barklike call. Once abundant through�  out the plains of the western U.S., part of southern Canada, and northern  Mexico, they are now found mostly in isolated or protected areas. They  are 12-17 in. (30-43 cm) long, including a 1-5-in. (3-12-cm) tail. Their  main diet is grass. Colonies consist of well-defined territories defended  by a male, several females, and young. The burrows of the black-tailed  prairie dog have carefully tended funnel-shaped entry mounds that pre�  vent flooding and serve as lookout posts. The white-tailed prairie dog  inhabits higher altitudes, hibernates, and is less colonial.</p><p>Prairie school Group of architects, including Frank Lloyd Wright, who  created low-lying �prairie houses� in the U.S. Midwest c. 1900-17. Prai�  rie houses were generally built of brick, wood, and plaster, with stucco  walls and bands of casement windows. The Prairie architects emphasized  horizontal lines by using low roofs with wide, projecting eaves. They dis�  carded elaborate floor plans and detailing for flowing internal spaces orga�  nized around a central fireplace or hearth. The resulting low, spreading  structures are characterized by light, crossing volumes and spaces; they  reach out to nature, not to other buildings. Other architects working in the  style included George Grant Elmslie (1871-1952) and Barry Byrne</p><p>(1883-1967).</p><p>Prajapati \pr9-'ja-p9-te\ Creator figure in the Vedic period of India. In  early Vedic literature (see Veda), the name was applied to various primal  figures. Later it signified one deity, the �lord of all creatures,� who was  said to have produced the universe and all its beings after preparing him�  self through ascetic practices. Other stories allude to his own creation  from the primal waters. His female emanation was Vac, the personifica�  tion of the sacred word; Usas, the dawn, was identified as his female part�  ner or his daughter. In the post-Vedic age, Prajapati came to be identified  with Brahma.</p><p>Prajnaparamita Vpr9g- 1 nya- , par-3-me- l ta\ Body of sutras and their  commentaries in Mahayana Buddhism. The main texts, written 100 bce-  150 ce, represent prajna (wisdom) as the supreme perfection and the pri�  mary avenue to nirvana. The content of this wisdom is the realization that  all phenomena are illusory. The name Prajnaparamita also refers to the  personification of the literature or of wisdom, often depicted as a woman  with her hands in the teaching gesture or holding a lotus and sacred book.  See photograph opposite.</p><p>prakriti and purusha \'pr3-kri-te...'pu-ru-sh9\ In the Samkhya school  of Indian philosophy, material nature and the soul. Prakriti is material  nature in its germinal state, eternal and beyond perception. When it comes</p><p>into contact with the soul or self (purusha), it starts a process of evolu�  tion that leads through several stages to the creation of the existing mate�  rial world. In the Samkhya view, only prakriti is active; the self, trapped  in materiality, does nothing but observe and experience. The self escapes  from prakriti by recognizing its total difference from and noninvolvement  in the material world.</p><p>Pramoedya Ananta Toer or Pramudya Ananta Tur</p><p>Npra-'mud-ya-a-'nan-ta-'tthA (b. Feb. 20, 1925, Blora, Java, Indon.) Jav�  anese novelist and short-story writer. While imprisoned by the Dutch  (1947-49) for his role in the Indonesian revolt against renewed colonial  rule, Pramoedya wrote his first published novel, The Fugitive (1950).  After Indonesia gained independence in 1949, he began to produce works  written in a rich style that incorporates everyday speech and images from  classical Javanese culture. Imprisoned (1965-79) for his role in an  attempted communist coup, he wrote a series of four novels � This Earth  of Mankind (1980), Child of All Nations (1980), Footsteps (1985), and  House of Glass (1988)�that depict Javanese society under Dutch rule.  He is the preeminent prose writer of postindependence Indonesia.</p><p>Prandtl \'pran-t 3 l\, Ludwig (b. Feb. 4, 1875, Freising, Ger.�d. Aug.  15, 1953, Gottingen, W.Ger.) German physicist, considered the father of  aerodynamics. He taught at the University of Gottingen (1904-53). His  1904 discovery of the boundary layer at the surface of a body moving in  air or water led to an understanding of skin friction drag and of the way  streamlining (see streamline) reduces the drag of airplane wings and other  moving bodies. His work on wing theory explained the process of airflow  over airplane wings.</p><p>prasada Vpro-'sa-dsV In Hinduism, consecrated food offered to the deity  and then distributed to worshipers, who consume it as a sign of the god�s  favour. Prasada is used both in temple ceremonies, where it may be  offered to a god such as Krishna and then distributed by the priests, and  at household shrines, where it is offered to the god and then handed out  to household members. See also puja.</p><p>pratitya-samutpada Xpro-'tet-yo-.ss-mut-'pa-doV In Buddhism, the  chain of causation that leads from rebirth to death. Existence is seen as  an interrelated flux of transient events that occur in a series, one produc�  ing another, usually described as a chain of 12 links: (1) ignorance, which  leads to (2) faulty perceptions of reality, which provide the structure of  (3) knowledge, which addresses (4) name and form, or the principle of  individual identity and the sensory perception of an object, experienced  through (5) the six domains (the five senses and their object, along with  the mind), whose presence leads to (6) contact (between objects and the  senses), followed by (7) sensation, which, being pleasant, leads to (8)  thirst and then (9) grasping (as of sex partners), which leads to (10) the  process of becoming, culminating in (11) birth, and at last (12) old age  and death.</p><p>Pratt, E(dwin) J(ohn) (b.

It comprises schools of architecture,  art and design (for which it is especially renowned), liberal arts and sci�  ences, professional studies, and information and library science. It has  both bachelor�s and master�s degree programs.</p><p>pratyaya \pr9t-'ya-y9\ In Buddhism, an auxiliary, indirect cause, as dis�  tinguished from a direct cause ( hetu ). A seed, for example, is the direct  cause of a plant, whereas sunlight, water, and earth are the auxiliary  causes. Sometimes pratyaya is used to refer to cause in general. The idea  of causation is important in the Buddhist concept of the cycle of death  and rebirth (see pratitya-samutpada).</p><p>pratyeka-buddha \prot-'ya-k9\ In Buddhism, one who attains enlight�  enment through his own efforts rather than by listening to the teachings  of a buddha. The way of the self-enlightened buddha was retained only  in the Theravada tradition. Mahayana Buddhism rejects the path of self�  enlightenment as too limiting and embraces the ideal of the bodhisattva,  who postpones final enlightenment to work for the salvation of others.</p><p>Pravda \'prav-da\ Russian "Truth" Former daily newspaper published  in Moscow and distributed nationwide, the official organ of the Commu�  nist Party of the Soviet Union (1918-91). It was founded in St. Peters�  burg as an underground paper by Vladimir Ilich Lenin and two colleagues  in 1912. As a Soviet state newspaper and central source of information  and education, it offered well-written articles and analyses on science,  economics, cultural topics, and literature as well as materials to indoctri�  nate and inform readers on communist theory and programs. Topics con�  cerning international relations were largely left to the government paper  Izvestiya. After communist power ended in 1991, most of its readership  evaporated; it became the voice of the conservative-nationalist opposition  and ceased publication in 1996.</p><p>Praxiteles \prak-'si-t 3 l-,ez\ (fl. c. 370-330 bc, Greece) Greek sculptor.  His only known surviving work, the marble Hermes Carrying the Infant  Dionysus, displays delicate modeling and exquisite surface finish. A few  other works survive in Roman copies. His most celebrated work was the  Aphrodite of Cnidus, which Pliny the Elder considered the best statue in the  world. Through Praxiteles� influence, figures were increasingly shown  standing in graceful, sinuous poses, leaning lightly on some support, a  pose further developed by sculptors  of the Hellenistic Age. Greatest and  most original of the 4th-century Attic  sculptors, he profoundly influenced  the later course of Greek sculpture.</p><p>Prayag Raj See Allahabad</p><p>prayer Silent or spoken petition  made to God or a god. Prayer has  been practiced in all religions  throughout history. Its characteristic  postures (bowing the head, kneeling,  prostration) and position of the  hands (raised, outstretched, clasped)  signify an attitude of submission and  devotion. Prayer may involve con�  fessions of sin, requests, thanks,  praise, offerings of sacrifice, or prom�  ises of future acts of devotion. In  addition to spontaneous private  prayer, most religions have fixed for�  mulas of prayer (e.g., the Lord's  Prayer), often recited in group wor�  ship. The four prophetic religions  (Judaism, Christianity, Islam, and  Zoroastrianism) prescribe a daily set  form of individual prayer, such as the  Shema, to be recited twice a day by  every male Jew, and the Islamic  salat, performed five times a day.</p><p>prayer wheel In Tibetan Buddhism,  a mechanical device used as an  equivalent to the recitation of a man�  tra. The prayer wheel consists of a</p><p>hollow metal cylinder, often beautifully embossed, mounted on a rod and  containing a consecrated paper bearing a mantra. Each turn of the wheel  by hand is considered equivalent to orally reciting the prayer. Variants to  the handheld prayer wheel are large cylinders that can be set in motion  by hand or attached to windmills or waterwheels and thus kept in con�  tinuous motion.</p><p>praying mantis See mantis</p><p>Pre-Raphaelites X.pre-'ra-fe-a-JItsN Group of young British painters,  led by Dante Gabriel Rossetti, William Holman Hunt, and John Everett Mill�  ais, who banded together in 1848 in reaction against what they considered  the unimaginative and artificial historical painting of the 18th and early  19th centuries, seeking to express a new moral seriousness and sincerity  in their works. Their name, the Pre-Raphaelite Brotherhood, honoured the  simple depiction of nature in Italian art before Raphael; the symbolism,  imagery, and mannered style of their paintings often suggest a faux-  medieval world. Later members included Edward Burne-Jones and George  Frederic Watts (1817-1904). The group also functioned as a school of  writers who often used medieval settings, sometimes with shocking effect,  as in William Morris�s The Defence ofGuenevere (1858), which deals with  issues of love and sex. Though active less than 10 years, the group had a  profound influence on the arts.</p><p>pre-Socratics Earliest Greek philosophers (those who preceded  Socrates) whose attention to questions about the origin and nature of the  physical world has led to their being called cosmologists or naturalists.  Among the most significant were the Milesians Thales, Anaximander, and  Anaximenes, Xenophanes of Colophon, Parmenides, Heracleitus of Ephesus,  Empedocles, Anaxagoras, Democritus, Zeno of Elea, and Pythagoras.</p><p>Preakness Stakes One of the three classic U.S. horse races making  up the Triple Crown.

April 17, 1901, Tucuman, Arg.�d. April  29, 1986, Las Vertientes, near Santiago, Chile) Argentine economist and  statesman. Serving in various positions in Argentine government and aca�  demia, he advised developing countries to stimulate domestic manufac�  turing to reduce their reliance on imports and thus their dependence on  the industrialized nations. He also advocated the economic integration of  Latin America to achieve economies of scale and land reform to reduce  the income inequalities that impeded the growth of the domestic market.  As the influential head of the UN�s Economic Commission for Latin  America, he addressed inequities in the trade relationships between  wealthy and poor nations.</p><p>Precambrian time Interval of geologic time from c. 3.8 billion years  ago, the age of the oldest known rocks, to 544 million years ago, the  beginning of the Cambrian Period. This interval represents more than 80%  of the geologic record and thus provides important evidence of how the  continents evolved. The Precambrian is divided into the Archean and  Proterozoic eons, with the boundary between them at 2.5 billion years  ago. It was originally defined as the era that predated the emergence of  life in the Cambrian Period. It is now known, however, that life on Earth  had begun by the early Archean. Soft-bodied organisms without skeletons  began to appear toward the end of the Precambrian.</p><p>precast concrete Concrete cast into structural members under factory  conditions and then brought to the building site. A 20th-century develop�  ment, precasting increases the strength and finish durability of the mem�  ber and decreases time and construction costs. Concrete cures slowly; the  design strength is usually reached 28 days after initial setting. Using pre�  cast concrete eliminates the lag between the time on-site concrete is placed  and the time it can carry loads. Precast concrete components include slabs,  beams, columns, walls, stairways, modular boxes, and even kitchens and  bathrooms with precast fixtures. See also prefabrication.</p><p>precession Phenomenon associated with the action of a gyroscope or a  spinning top and consisting of a comparatively slow rotation of the axis  of rotation of a spinning body about a line intersecting the spin axis. It  arises as a result of external torque acting on the body. One example of  precession is the smooth, slow circling of a spinning top (the uneven  wobbling is called nutation). Precession of the earth�s axis of rotation is  the reason that the positions of celestial bodies appear to drift systemati�  cally with the passage of time. See also precession of the equinoxes.</p><p>Tibetan prayer wheel, gilt silver, 18th�  19th century; in the Seattle (Washing�  ton) Art Museum.</p><p>COURTESY OF THE SEATTLE ART MUSEUM, WASHINGTON,  EUGENE FULLER MEMORIAL COLLECTION</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1542 I precipitation &#x25BA; prelude</p><p>precipitation All liquid and solid water particles that fall from clouds  and reach the ground, including drizzle, rain, snow, ice crystals, and hail.  The essential difference between a precipitation particle and a cloud par�  ticle is size; an average raindrop has a mass equivalent to that of about  one million cloud droplets. Precipitation elements (ice crystals or drop�  lets that form around soluble particles such as salt) form directly from the  vapour state and get larger through collision and coalescence. Eventually  they become large enough to respond to gravity, and they fall to the  ground.</p><p>Precisionism Smooth, precise technique used primarily in the 1920s  by several U.S. painters in representational canvases depicting sharply  defined forms, such as urban skylines; the industrial landscape of facto�  ries and smokestacks, buildings, and machinery; and country landscapes  with grain elevators and barns or empty desert and sky. The scenes are  always devoid of people or signs of human activity. Precisionism is a  �cool� art, which keeps the viewer at a distance. It had its origins in Cub�  ism, Futurism, and Orphism; in turn it influenced Pop art. Though it was not  a school or movement with a formal program, the Precisionist artists,  including Charles Demuth and Georgia O'Keeffe, often exhibited together.</p><p>predation Form of food getting in which one animal, the predator, eats  an animal of another species, the prey, immediately after killing it or, in  some cases, while it is still alive. Most predators are generalists; they eat  a variety of prey species. Specialist predators, such as anteaters, eat only  one or a few prey species. Cannibalism is a type of predation in which  an animal eats another of its own species. Seed consumption is also con�  sidered predation because the entire living embryo of a plant is destroyed.</p><p>predestination In Christianity, the doctrine that God has long ago  determined who will be saved and who will be damned. Three types of  predestination doctrine have developed. One doctrine holds that God  singled out the saved because he foresaw their future merits. A second  doctrine (often identified with John Calvin) states that from eternity God  has determined the saved and the damned, regardless of their merit or  lack thereof. A third doctrine, set forth by Thomas Aquinas and Martin  Luther, ascribes salvation to the unmerited grace of God but links the lack  of grace to sin. In Islam, issues of predestination and free will were argued  extensively. The Mutazila held that God would be unjust if he predestined  all human actions; the Ashariya advocated a strict predestination that  became the mainstream Islamic view.</p><p>predicate calculus Part of modern symbolic logic which systemati�  cally exhibits the logical relations between propositions involving quan�  tifiers such as �all� and �some.� The predicate calculus usually builds on  some form of the propositional calculus and introduces quantifiers, indi�  vidual variables, and predicate letters. A sentence of the form �All F�s are  either G�s or H�s� is symbolically rendered as (Vx)[Fx z&gt; (Gx v Hx)J, and  �Some F�s are both G�s and H�s� is symbolically rendered as (3x)[Fx a  (Gx a Hx)]. Once conditions of truth and falsity for the basic types of  propositions have been determined, the propositions formulable within the  calculus are grouped into three mutually exclusive classes: (1) those that  are true on every possible specification of the meaning of their predicate  signs, such as �Everything is F or is not F�; (2) those false on every such  specification, such as �Something is F and not F�; and (3) those true on  some specifications and false on others, such as �Something is F and is  G.� These are called, respectively, the valid, inconsistent, and contingent  propositions. Certain valid proposition types may be selected as axioms  or as the basis for rules of inference. There exist multiple complete axi-  omatizations of first-order (or lower) predicate calculus (�first-order�  meaning that quantifiers bind individual variables but not variables rang�  ing over predicates of individuals). See also logic.</p><p>preeclampsia V.pre-i-'klamp-se-oV and eclampsia Hypertensive  conditions unique to pregnancy. Preeclampsia is marked by hypertension,  protein in the urine, and hand and face edema, which develop late in preg�  nancy or soon after. Persistent hypertension compromises the fetus�s  blood supply and damages the mother�s kidneys. Monitoring of blood  pressure and weight gain may detect it before symptoms (headaches,  visual disturbances, stomach pain) begin. Eclampsia follows in about 5%  of cases, with convulsions that pose a serious threat to mother and child.  It can usually be prevented by special diets, drugs, and limited activity  or early delivery.</p><p>preemption \pre-'emp-sh3n\ U.S. policy that allowed the first settlers,  or squatters, on public land to buy the land they had improved. Since  improved land, coveted by speculators, was often priced too high for</p><p>squatters to buy at auction, temporary preemptive laws allowed them to  acquire it without bidding. The Pre-Emption Act (1841) gave squatters  the right to buy 160 acres at $1.25 per acre before the land was auctioned.  The Homestead Act (1862) made preemption an accepted part of U.S.  land policy. See also Homestead Movement.</p><p>prefabrication Assembly of standardized building components at a  location other than the building site. Units may include doors, stairs, win�  dow walls, wall panels, floor panels, roof trusses, room-sized components,  and even entire buildings. Prefabrication requires the cooperation of archi�  tects, suppliers, and builders regarding the size of basic modular units. In  the U.S. building industry, the 4-by-8-ft (1.2-by-2.4-m) panel is a stan�  dard unit; the architect�s drafted building plans and the supplier�s pre�  fabricated wall units are based on multiples of that module. Advantages  of prefabrication include the cost savings of mass production, the oppor�  tunity to use specialized equipment to produce components, and stan�  dardization of parts for quick assembly and erection. The major drawback  is in assigning responsibility for quality control. See also precast concrete.</p><p>prefect In ancient Rome, any of various high officials with primarily  judicial and administrative responsibilities. In the early republic, a prefect  of the city (praefectus urbi ) took over the consul�s duties during their  absence from Rome. The office lost some importance after the introduc�  tion of praetors (mid 4th century bc). Augustus revitalized the office when  he appointed five prefects to supervise the city government, the fire bri�  gade, the grain supply, and the Praetorian Guard. The praetorian prefects  acquired great power and often became virtual prime ministers.</p><p>pregnancy Process of human gestation that takes place in the female�s  body as a fetus develops, from fertilization to birth (see parturition). It  begins when a viable sperm from the male and egg from the ovary merge  in the fallopian tube (see fertility; fertilization). The fertilized egg (zygote)  grows by cell division as it moves toward the uterus, where it implants in  the lining and grows into an embryo and then a fetus. A placenta and  umbilical cord develop for nutrient and waste exchange between the cir�  culations of mother and fetus. A protective fluid-filled amniotic sac  encloses and cushions the fetus. Early in pregnancy, higher estrogen and  progesterone levels halt menstruation, cause nausea, often with vomiting  (morning sickness), and enlarge the breasts and prepare them for lacta�  tion. As the fetus grows, so does the uterus, displacing other organs. Nor�  mal weight gain in pregnancy is 20-25 lbs (9-11.5 kg). The fetus�s  nutritional needs require the mother to take in more calories and espe�  cially protein, water, calcium, and iron. Folic-acid supplements are rec�  ommended during early pregnancy to prevent neural tube defects. Smoking,  alcohol, and many legal and illegal drugs can cause congenital disorders  and should be avoided during pregnancy. Ultrasound imaging is often  used to monitor structural and functional progress of the growing fetus.  The due date is estimated as 280 days from the time of last menstruation;  90% of babies are born within two weeks of the estimated date. See also  amniocentesis; preeciampsia and eclampsia; premature birth. See illustration on  opposite page.</p><p>prehistoric religion Religious practices and beliefs of prehistoric  peoples, as inferred from archaeological findings. The oldest burials that  attest to a belief in life after death date from 50,000-30,000 bc. Corpses  were buried with goods such as stone tools and parts of animals, sug�  gesting an attempt to placate the dead or equip them for the next world.  The Middle Paleolithic Period provides the first evidence of animal sacri�  fices, which may have been offerings to the dead, to a higher power, or to  the fertility of the animal species. Prehistoric human sacrifices have also  been found, usually of women and children. From the Bronze Age on,  weapons and jewelry were often thrown into springs, wells, and other  bodies of water as sacrifices (probably of war booty). Animals such as  bears were important in prehistoric religion from the Upper Paleolithic  Period on, probably seen as guardian spirits and associated with magical  powers. Fertility rites were also practiced, as evidenced by small, corpu�  lent female figures, known as Venus statuettes, with highly emphasized  breasts and buttocks.</p><p>prelude Musical composition, usually brief, generally played as an  introduction to another piece. The prelude originated as short pieces that  were improvised by an organist to establish the key of a following piece  or to fill brief interludes in a church service. Their improvisatory origins  were often reflected in rhythmic freedom and virtuosic runs. A section in  this style would often lead to a closing fugal section; in time this turned  into a separate movement, and preludes came to be paired with fugues.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>premature birth &#x25BA; prerogative court I 1543</p><p>chorionic villi</p><p>decidua</p><p>basalis</p><p>placenta</p><p>intervillus space</p><p>umbilical</p><p>arteries</p><p>umbilical  cord</p><p>chorion  amnion</p><p>uterus</p><p>amniotic cavity</p><p>mucus plug</p><p>Full-term fetus in the uterus. The amnion, formed from the inner embryonic mem�  brane, encloses the fetus. The space between the amnion and fetus (amniotic cavity)  is filled with the watery amniotic fluid. The outermost embryonic membrane, the  chorion, has developed fingerlike projections (villi) on its outer surface, which have  enlarged and penetrated the decidua basalis layer of the uterus. The chorionic villi  and the decidua basalis form the placenta. Maternal blood fills the spaces around  the villi (intervillous spaces); oxygen and nutrients diffuse into the villi and pass on  to the fetus via the umbilical vein. Waste materials that leave the fetus via the  umbilical arteries diffuse out of the villi into the mother's blood.</p><p>� MERRIAM-WEBSTER INC.</p><p>In the 17th century, preludes began to be frequently written for lute or  harpsichord.

Infants  bom as early as 23-24 weeks may survive but many face lifelong dis�  abilities (e.g., cerebral palsy, blindness, deafness). Premature infants  account for 8-9% of live births but two-thirds of infant deaths. 40-50%  of cases have no explanation; other cases can be attributed to such causes  as maternal hypertension or diabetes, multiple pregnancy, or placental  separation. With good care, about 85% of live-born premature infants  should survive. Infants born very early (before 32-34 weeks) lack fully  developed lungs and often develop respiratory distress syndrome. They also  have problems maintaining body temperature and fighting infection. Most  deaths result from breathing problems, infections, and brain or lung hem�  orrhages. Premature infants are characterized by low birth weight, small  size, irregular breathing, absence of subcutaneous fat, and thin skin.</p><p>premenstrual syndrome (PMS) Variable group of symptoms  occurring before menstruation in 40% of women, severe in about 10% of  those. Physical symptoms may include headache, cramps, bloating, and  constipation or diarrhea. Emotional symptoms range from irritability, leth�  argy, and mood swings to hostility, confusion, and depression. Theories as  to the cause centre on hormones, nutrition, and stress (known to affect  severity). Depending on the symptoms, treatment may involve exercise,  stress management, nutritional therapy, or drugs. Dietary measures include  low sodium and high protein and complex carbohydrate intake and avoid�  ance of xanthines (including caffeine). Increasing calcium intake has been  shown to prevent or reduce cramps, which are best treated with ibuprofen.</p><p>premier See prime minister</p><p>Preminger Vpre-min-joiA, Otto (Ludwig) (b.

While studying law in his native Vienna, he worked with Max  Reinhardt�s theatre and soon became its director. In 1935 he went to the  U.S. to direct Libel on Broadway. Invited to Hollywood, he made the suc�  cessful thriller Laura (1944), which helped establish film noir. Forming  his own production company, he defied Hollywood�s Production Code  with a series of controversial films and brought about the relaxation of  censorship regulations. His landmark films include The Moon Is Blue  (1953); the all-African American Carmen Jones (1954); and The Man with  the Golden Arm (1955), a tale of drug addiction. His later films include  Anatomy of a Murder (1959), Exodus (1960), The Cardinal (1963), and  Hurry Sundown (1967).

After study in Paris (1891-  94), he spent much of his career traveling and painting abroad. He was  the first U.S. artist to fully absorb French Impressionism and Post-  Impressionism. His lively street scenes feature floating geometric areas of  brilliant decorative colour with a mosaiclike effect. He produced his most  outstanding works in watercolour. In his later years he lived in New York  City and exhibited with The Eight and in the 1913 Armory Show.</p><p>Prensa Ypren-sa\, La Spanish "The Press" Argentine daily newspa�  per, widely regarded as the finest Spanish-language newspaper in the  world. Founded in Buenos Aires in 1869, it soon broke with the tradi�  tional emphasis on propaganda to stress professional, accurate news  reporting and independence in editorial opinion. It displayed a concern  for human welfare that persisted in the face of government harassment,  notably in the 1940s under the regime of Juan Peron. In 1951 it was seized  and became a Peronist propaganda organ; after Peron�s overthrow, it reap�  peared as an independent daily in 1956.</p><p>Preobrajenska, Olga orig.

She joined the Mariinsky Ballet  (see Mariinsky Theatre) in 1889 and earned the title of prima ballerina in  1900. Her lyrical creativity and love of improvisation were praised by  audiences and critics. She also taught at the Imperial Theatre School  (1901-02 and 1914-21, during which time the school was renamed the  Petrograd State Ballet School). As an instructor, she helped to form the  next generation of Russian dancers. In 1922 she emigrated from Russia  and taught at her own ballet school in Paris (1923-60).</p><p>preparatory school School that prepares students for entrance to a  higher school. In Europe, where secondary education has been selective,  preparatory schools have been those that catered to pupils wishing to enter  the academic secondary schools.

The presbyters who govern the church are grouped in a  hierarchy of courts, the highest of which is the general assembly. They  are elected by the members of the congregation for fixed terms, in a sys�  tem intended to affirm the equality of all Christians. The term Presbyte�  rianism also refers to a denomination, the Presbyterian Church. The  modern Presbyterian churches trace their origins to the Calvinist churches  of the British Isles; in continental Europe such congregations were known  as Reformed churches. The Presbyterian Church is strongest in Scotland,  where it was founded by John Knox in 1557, but it is also well established  in England, Wales, and the U.S. See also Calvinism.</p><p>preschool education Childhood education during the period from  infancy to age five or six. Institutions for preschool education vary widely  around the world, as do their names (e.g., infant school, day care, mater�  nal school, nursery school, creche, kindergarten). The first systematic  theory of early childhood pedagogy was propounded by Friedrich Froebel,  the founder of the kindergarten. Other influential theorists include Maria  Montessori and Jean Piaget. Of major concern in preschool education is  language development; teachers often conduct listening and language  games. See also elementary education.</p><p>Prescott, Edward C. (b. Dec. 26, 1940, Glens Falls, N.Y., U.S.) U.S.  economist. Prescott studied at Swarthmore College (B.A., 1962), Case  Western Reserve University (M.S., 1963), and Carnegie Mellon Univer�  sity (Ph.D., 1967), where he later taught and advised Finn E. Kydland on  his doctorate. Working with Kydland, he demonstrated how a declared  commitment to a low inflation rate by policy makers might create expec�  tations of low inflation and unemployment rates. The two men also estab�  lished the microeconomic foundation for business cycle analyses,  demonstrating that technology changes or supply shocks, such as oil price  hikes, could be reflected in investment and relative price movements and  thereby create short-term fluctuations around the long-term economic  growth path. In 2004 Prescott shared the Nobel Prize for Economics with  Kydland.</p><p>Prescott, William H(ickling) (b. May 4, 1796, Salem, Mass.,  U.S.�d. Jan. 28, 1859, Boston, Mass.) U.S. historian. Bom to a prosper�  ous family, Prescott graduated from Harvard University in 1814 but was  prevented by poor health and eyesight from a career in law or business.  His friends, including Washington Irving, led him to his life�s work:  recounting the history of 16th-century Spain and its colonies. He is best  known for his History of the Conquest of Mexico (1843) and History of  the Conquest of Peru (1847), for which he made rigorous use of original  sources, and which earned him a reputation as the first scientific U.S. his�  torian.</p><p>prescription In property law, the effect of the lapse of time in creating  and destroying rights. Acquisitive prescription allows an individual, after  unequivocal possession for a specific period, to acquire an interest in real  property, such as an easement, but not the property itself. See also adverse  possession.</p><p>prescriptivism In metaethics, the view that moral judgments are pre�  scriptions and therefore have the logical form of imperatives. Prescrip�  tivism was first advocated by Richard M. Hare (born 1919) in The  Language of Morals (1952). Hare argued that it is impossible to derive  any prescription from a set of descriptive sentences, but tried neverthe�  less to provide a foothold for moral reasoning in the constraint that moral  judgments must be �universalizable�: that is, that if one judges a particu�  lar action to be wrong, one must also judge any relevantly similar action  to be wrong. Universalizability is not a substantive moral principle but a  logical feature of the moral terms: anyone who uses such terms as �right�  and �ought� is logically committed to universalizability.</p><p>preservation, food See food preservation</p><p>preservative Any of numerous chemical additives used to prevent or  slow food spoilage caused by chemical changes (e.g., oxidation, mold  growth) and maintain a fresh appearance and consistency.

Some preservatives also improve the appear�  ance of the product (e.g., sodium nitrate and nitrite in meats).</p><p>president In government, the officer who serves as head of state and  sometimes also as chief executive. In countries where the president is  chief of state but not of government, the role is largely ceremonial, with  few or no political powers. Presidents may be elected directly or indi�  rectly, for a limited or unlimited number of terms. In the U.S., the presi�  dent�s chief duty is to ensure that the laws are faithfully executed, which  he does through various executive agencies and with the aid of his cabi�  net. He also serves as commander in chief of the armed forces, nominates  judges to the Supreme Court, and makes treaties with foreign governments  (contingent on Senate approval). The office of president is used in gov�  ernments in South and Central America, Africa, and elsewhere. In west�  ern Europe executive power is generally vested in a prime minister and his  cabinet, and the president, where the office exists, has few responsibili�  ties (though France is a significant exception).</p><p>Presley, Elvis (Aaron) (b. Jan. 8, 1935, Tupelo, Miss., U.S.�d. Aug.  16, 1977, Memphis, Tenn.) U.S. popular singer, the �King of Rock and  Roll.� Presley was raised in Memphis, where he sang Pentecostal church  music and listened to black bluesmen and Grand Ole Opry broadcasts. In  1954 he began to record for the producer Sam Phillips, who had been  searching for a white singer who sounded like a black man. In 1956, under  his new manager, �Colonel� Tom Parker, he released �Heartbreak Hotel,�  the first of numerous million-selling hits that included �Hound Dog� and  �All Shook Up.� In the same year, he appeared in Love Me Tender , the  first of 33 mediocre films, and on several TV shows, notably the Ed Sul�  livan Show. Presley�s intensely charismatic style�including his sexy hip  shaking, ducktail haircut, and characteristic sneer�excited young fans,  especially females, to wild adulation. After a stint in the army (1958-60)  he resumed recording and acting, but his earlier raucous style was mod�  erated. In 1968 he introduced a Las Vegas-based touring act with orches�  tra and gospel-type choir. Battling public pressures, weight gain, and drug  dependence, he underwent a personal decline. His death at age 42, attrib�  uted to natural causes, was mourned by hundreds of thousands of fans at  Graceland, his Memphis estate, which remains a place of international  pilgrimage.</p><p>Prespa, Lake Lake on the boundary between Macedonia, Albania, and  Greece.

Austria  agreed to admit the electors of Bavaria and Wurttemberg, allied with  Napoleon, to the rank of kings, which further reduced Austrian influence  in Germany. Austria�s influence was also excluded from Italy. The treaty  enabled Napoleon to create a ring of French client states beyond France.</p><p>pressure Perpendicular force per unit area, or stress at a point within a  confined fluid. A solid object exerts pressure on a floor equal to its weight  divided by the area of contact. The weight of the Earth�s atmosphere on  the surface constitutes atmospheric pressure, which varies from place to  place but always decreases with altitude. The pressure exerted by a con�  fined gas results from the average effect of the forces produced on the  walls of the container by the continual, numerous collisions by gas mol�  ecules. Hydrostatic pressure is the stress, or pressure, exerted equally in  all directions at points within a confined fluid. Lithostatic pressure is the  stress exerted on a body of rock in the Earth�s crust by surrounding rock,  which increases with depth below the surface.

He was believed  to be a Nestorian and a king-priest (prester being short for presbyter,  �elder� or �priest�) reigning in an unspecified part of the Far East. The  legend arose during the Crusades in the 12th century, among European  Christians who hoped that Prester John would prove an ally in the effort  to regain the Holy Land from the Saracens. In the 13th�14th century vari�  ous missionaries and travelers, including Marco Polo, searched for his  kingdom in Asia. After the mid-14th century, Ethiopia was the centre of  the quest, as Prester John became identified with the emperor of that Afri�  can Christian nation.</p><p>Prestes \'pras-tas\, Luis Carlos (b.

It was  the site of the Lancashire Royalist headquarters during the English Civil  Wars. The Royalists were defeated there by Oliver Cromwell in 1648.  Despite the decline of the cotton textile industry, the economy has  remained strong through diversification, and it produces aircraft and  motor vehicles.</p><p>prestressed concrete Concrete reinforced by either pretensioning or  posttensioning, allowing it to carry a greater load or span a greater dis�  tance than ordinary reinforced concrete. In pretensioning, lengths of steel  wire or cables are laid in the empty mold and stretched. The concrete is  placed and allowed to set, and the cables are released, placing the con�  crete into compression as the steel shrinks back to its original length. In  posttensioning, the steel in the concrete is stretched after the curing pro�  cess. Prestressing places a concrete member in compression; these com�  pressive stresses counteract the tensile bending stresses of an applied load.  The process was developed by the French engineer Eugene Fressinet in  the early 20th century.</p><p>Pretoria \pri-'tor-e-9\ City (pop., 2005 est.: metro, area, 1,282,000),  administrative capital of the Republic of South Africa.

In 1899, during the South  African War (1899-1902), Winston Churchill was imprisoned there until  his escape. Pretoria is primarily a seat of government, and most people  are employed in the service sector. It is also an important rail centre, with  an industrial economy based on iron and steel.

In 1842 he led  an unsuccessful fight with the British over the annexation of Natal. Fol�  lowing British annexation of Transvaal in 1848, his forces again attacked  and were again defeated. In 1852 he participated in the Sand River Con�  vention, where Transvaal independence was recognized. He led negotia�  tions for independence of the Orange River Sovereignty, finally  guaranteed by the Bloemfontein Convention of 1854. His son Marthinus  Wessel Pretorius (1819-1901) was the first president of the South Afri�  can Republic (1857, 1864, 1869) and president of the Orange Free State  (1859-63).

Operating as a measure of value, prices perform a sig�  nificant economic function, distributing the scarce supply of goods.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1546 I Price &#x25BA; Priestley</p><p>services, and resources to those who most want them through the adjust�  ments of supply and demand. Prices of resources are called wages, interest,  and rent. This system, known as the price mechanism, is based on the  principle that only by allowing prices to move freely will the supply of  any given commodity match demand. If supply is excessive, prices will  be low and production will be reduced; this will cause prices to rise until  there is a balance of demand and supply. If supply is inadequate, prices  will be high, prompting an increase in production that in turn will lead to  a reduction in prices until supply and demand are in equilibrium. A totally  free price mechanism does not exist in practice; even in free-market  economies, monopolies or government regulation may limit the efficiency  of price as a determinant of supply and demand. In centrally planned  economies, the price mechanism may be supplanted by centralized gov�  ernment control. Attempts to operate an economy without a price mecha�  nism usually result in surpluses of unwanted goods, shortages of desired  products, black markets, and stunted economic growth.</p><p>Price, (Mary Violet) Leontyne (b.

Price indexes were first developed to  measure changes in the cost of living in order to determine the wage  increases necessary to maintain a constant standard of living. There are  two basic types. Laspeyres-type indexes define a market basket of goods  in a base period, then use the prices for those goods to examine change  over space and time. In its simplest form, this is simply the ratio of what  those goods cost today to what they cost in the base period. The two most  familiar indexes of this type are the consumer price index (CPI) and the  producer price index (PPI). The CPI measures changes in retail prices in  such component parts as food, clothing, and shelter. The PPI (formerly  called the wholesale price index) measures changes in the prices charged  by manufacturers and wholesalers. Paasche-type indexes define a market  basket of goods in the current period, then use the prices of those goods  from past periods. The most familiar index of this type is the GDP defla�  tor, used in the U.S. in the national income accounting to differentiate  amounts in constant dollars from those in current dollars.</p><p>prickly pear Any of a group of flat-stemmed, spiny opuntia cacti (see  cactus), native to the Western Hemisphere, or the edible fruit of certain  species. Engelmann prickly pear ( Opuntia engelmannii) and beaver tail  cactus ( O . basilaris ) commonly occur in the southwestern U.S. The Indian  fig ( O. ficus-indica) is an important food in tropical and subtropical coun�  tries. Because their stems have a high water content, prickly pears can be</p><p>used as forage crops and emergency  stock feed during drought. Some  species are cultivated as ornamentals  and valued for their large flowers.</p><p>Pride, Sir Thomas (b. Somer�  set?, Eng.�d. Oct. 23, 1658,</p><p>Worcester House, Surrey) English  soldier. Joining the Parliamentary  army in the English Civil Wars, he  commanded a regiment in the Battle  of Naseby (1645), then served with  Oliver Cromwell and helped rout the  invading Scots at Preston (1648).</p><p>When the army, dominated by the  Independents, occupied London later  that year, Pride arrested or expelled  about 140 Presbyterian members  from the House of Commons  (�Pride�s Purge�).

May 11, 1900, Ayut-  thaya, Siam�d. May 2, 1983, Paris, France) Thai political leader and  prime minister. He earned a doctorate in law in France, where he was  influenced by socialism and where, with Luang Phibunsongkhram and oth�  ers, he plotted to overthrow the absolute monarchy in Siam (Thailand).  Pridi participated in the Promoters Revolution and helped write the con�  stitution of December 1932. He engineered the downfall of Phibun-  songkhram�s pro-Japanese government (1944) and in 1946 became  Thailand�s first popularly elected prime minister. Unjustly held respon�  sible for the assassination of King Ananda that year, he was forced to  resign and flee the country in 1947. He lived in China until 1970, when  he moved to France.</p><p>Priene \pri-'e-ne\ Ancient city of Ionia, north of the Menderes (Maean-  der) River, southwestern Anatolia. According to Strabo, it was founded  by Ionians and Thebans. It was sacked in the 7th century bc but regained  its position in the 6th century bc. It prospered under the Romans and Byz�  antines but gradually declined. After passing into Turkish hands in the  13th century ad, it was abandoned. Archaeological excavations revealed  a Greek town built on terraces; atop a nearby hill is a temple of Athena  Polias that was dedicated by Alexander the Great in 334 bc.</p><p>priesthood Office of a spiritual leader expert in the ceremonies of wor�  ship and the performance of religious rituals. Though chieftains, kings,  and heads of households have sometimes performed priestly functions, in  most civilizations the priesthood is a specialized office. The priest�s duties  are concerned less with magic than with the right performance of ritual  acts required by the divine powers. Many African societies, for example,  differentiated between shamans and the priests responsible for the wor�  ship of tribal ancestors. Sacrifice is often one of the most important duties  of the priesthood. Not every highly developed religion possesses a priest�  hood, the most notable exception being Islam. The idea of the �priesthood  of all believers� was also a cardinal doctrine of the Reformation, and the  Protestant belief that priests are not needed as intermediaries between  church members and the Holy Spirit is seen most clearly in sects such as  the Society of Friends.</p><p>Priestley, Joseph (b. March 13, 1733, Birstall Fieldhead, near Leeds,  Yorkshire, Eng.�d. Feb. 6, 1804, Northumberland, Pa., U.S.) English  theologian, political theorist, and physical scientist. He worked as a  teacher and lecturer in various subjects before joining the ministry in  1767. His early scientific studies resulted in his History and Present State  of Electricity (1767), which became a fundamental text in the field. His  Essay on Government (1768) influenced later utilitarianism. He did impor�  tant work in the field of chemical reactions and change. He is considered  the discoverer of nitrogen, carbon monoxide, ammonia, and several other  gases, and in 1774 he became the first to identify oxygen; his report led  Antoine Lavoisier to repeat the experiment, deduce oxygen�s nature and  role, and name it. His theological works include History of the Corrup�  tions of the Christian Church (1782), burned as sacrilegious in 1785, and  A General History of the Christian Church, 6 vol. (1790-1802).

The formal primary system is peculiar to the U.S., where it  came into widespread use in the early 20th century. Most U.S. states use it  for elections to statewide offices and to the national presidency; in presi�  dential elections, delegates are selected to attend a national convention,  where they vote for the candidate to whom they are pledged. A closed-vote  primary is restricted to party members; an open-vote primary is open to all  voters in the district. Names can be placed on a ballot by an eligible citi�  zen�s declaration of candidacy, by nomination at a pre-primary convention,  or by a petition signed by a required number of voters. In the late 20th and  early 21st centuries political parties in some countries (e.g., the United  Kingdom and Israel) adopted similar procedures for the election of the  national party leader. See also electoral system; party system.</p><p>primate Any of more than 300 species of the order Primates, including  monkeys, apes, humans, and others. Primates are distinguished from other  mammals by one or more of the following traits: unspecialized structure,  specialized behaviour, a short muzzle, comparatively poor sense of smell,  prehensile five-digit hands and feet possessing flat nails instead of claws,  acute vision with depth perception due to forward-facing eyes, a large  brain, and prolonged pre- and postnatal development. Most species bear  a single young and live in troops headed by a male. The primates are one  of the most diverse orders of mammals on Earth. They include the lemurs  (more than 70 species in six families), the LORises (three or more species  in one subfamily), the tarsiers (six or more species in one family), the  New World monkeys (almost 100 species in five families), the Old World  monkeys (more than 100 species in one family), and the apes and humans  (about 20 species in two families). The oldest known fossil remains of  primates are about 60 million years old.</p><p>Primaticcio V.pre-mo-'tet-choV, Francesco (b. April 30, 1504, Bolo�  gna, Emilia�d. 1570, Paris, France) Italian-born French painter, sculp�  tor, and architect. In 1532 Francis I invited him to help redecorate the  Fontainebleau Palace, and Primaticcio became one of the principal artists  in France; he remained there the rest of his life, making only brief trips  to Italy. His decorative style in painting and stucco sculpture stressed the  human figure; the exaggerated musculature and active, elongated forms  of his figures greatly influenced 16th-century French art. One of the first  artists in France to replace religious themes with those of Classical  mythology, he brought a quiet French elegance to Italian Mannerism.</p><p>prime minister or premier \pri-'mir, pri-'mynA Head of the execu�  tive branch of government in states with a parliamentary system (see par�  liamentary democracy). The prime minister is the leader of the political party  or coalition with a governing majority, and is formally appointed by the  head of state. The office was developed in Britain by Robert Walpole; its  powers were consolidated by William Pitt the Younger. The British prime  ministry has served as a model for the heads of government in many  Commonwealth countries, Europe, and Japan. The prime minister has  appointive powers and is responsible for the government�s legislative  program, budget, and other policies. His term of office lasts until the next  scheduled election or until he loses legislative support. In France, which  has both a president and a prime minister, the president wields greater  power but the prime minister controls the domestic legislative agenda.  See also chancellor.</p><p>prime number Any positive integer greater than 1 and exactly divis�  ible only by 1 and itself. The sequence of prime numbers begins 2, 3, 5,  7, 11, 13, 17, 19, 23, 29... but follows no discernible pattern. The issues  of the regularities and irregularities in the distribution of primes are among  the most important questions in number theory. Primes have been recog�  nized at least since Pythagoras. It has been known that there are infinitely  many of them at least since Euclid. The prime-number factors of an inte�  ger are the prime numbers whose product is that integer (see fundamental  THEOREM OF ARITHMETIC).</p><p>Primo de Rivera Vpre-mo-tha-ri-'ver-oX, Jose Antonio (b. April 24,  1903, Madrid, Spain�d. Nov. 20, 1936, Alicante) Spanish politician. Son  of the dictator Miguel Primo de Rivera, he began a legal career in 1925. In  1933 he founded the Spanish fascist party, the Falange, and was elected  to the Cortes (parliament). He expounded his views in his periodicals F.E.  (1934) and Arriba (1935) and made speeches across Spain. After the left�</p><p>ist Popular Front came to power (1936), he was arrested, given a sum�  mary trial, and executed at age 33. He was treated as a martyr by Francisco  Franco�s Nationalist movement.</p><p>Primo de Rivera, Miguel (b. Jan. 8, 1870, Cadiz, Spain�d. March  16, 1930, Paris, France) Spanish general and dictator of Spain (1923-30).  A military officer from 1888, he served as military governor of Cadiz  (1915-19), Valencia (1919-22), and Barcelona (1922-23), where he  firmly suppressed disorder. Believing the parliamentary system to be cor�  rupt, he took power in a coup in 1923, dissolved the Cortes (parliament),  and suspended constitutional guarantees. He successfully ended the  Moroccan War (1927), settled labour disputes, and undertook public  works, but he failed to implement agrarian reforms. Increasing discontent  with his repressive government and lack of support from the army forced  him to resign in 1930. Jose Antonio Primo de Rivera was his son.</p><p>primogeniture \ l pri-mo- , je-n3-,chur\ Preference in inheritance that is  given by law or custom to the eldest son and his issue. The motivation  for such a practice has usually been to keep the estate of the deceased, or  some part of it, whole and intact, and to acknowledge the importance of  age-seniority within the social hierarchy. It is no longer a recognized  principle of inheritance in most jurisdictions.</p><p>primrose Any flowering plant of the genus Primula, one of 28 genera  of the family Primulaceae. Primula includes more than 500 species, which  occur chiefly in the Northern Hemisphere in cool or mountainous regions.  The plants are low-growing, usually perennial herbs; a few are biennials.  Most species grow 25-50 cm (10-20 inches) tall, but some are as short  as 5 cm and others as tall as 120 cm. Many species are cultivated for their  attractive, five-petaled flowers, which may be red, pink, purple, blue,  white, or yellow. Other plants in the primrose family include cyclamens  and pimpernels. The evening primrose (family Onagraceae) is not a true  primrose.</p><p>Primus Vpri-mosV Pearl (b.

She made her dance debut as the first black member of the New  Dance Group in 1943 and formed her own company the next year. Her  anthropological research in Africa and the Caribbean led her to choreo�  graph works such as African Ceremonial (1944) and The Wedding (1961),  and she obtained a Ph.D. from Columbia University.</p><p>Prince orig. Prince Rogers Nelson (b. June 7, 1958, Minneapolis,  Minn., U.S.) U.S. singer and songwriter. The son of a jazz pianist, he  taught himself several instruments and formed his own bands as a teen�  ager. At age 19 he released his first album, on which he played all the  instruments. His second album, Prince (1979), was followed by many  others, including the best-selling 1999 (1982), the soundtrack of the film  Purple Rain (1983), in which he also starred, and Diamonds and Pearls  (1991). In 1993 he changed his name to an unpronounceable symbol and  became known as �the artist formerly known as Prince,� but in 2000 he  resumed his previous name. In 2004 he was inducted into the Rock and  Roll Hall of Fame.</p><p>prince European title of rank, usually denoting a person exercising com�  plete or almost complete sovereignty or a member of a royal family. The  wife of a prince is a princess. In Britain, the title was not used until 1301,  when Edward I invested his son, the future Edward II, as prince of Wales.  From Edward Ill�s time, the king�s (or queen�s) eldest son and heir has  usually been so invested.</p><p>Prince, Hal orig. Harold Smith Prince (b. Jan. 30, 1928, New York,  N.Y., U.S.) U.S. theatrical producer and director. He worked for the pro�  ducer George Abbott before coproducing the successful musical The  Pajama Game (1954). He went on to produce or coproduce over 30 hit  musicals, including Damn Yankees (1955), West Side Story (1957), A  Funny Thing Happened on the Way to the Forum (1962), and Fiddler on  the Roof( 1964). Frequently working with Stephen Sondheim, he won Tony  Awards for his direction of the musicals Cabaret (1966), Company (1970),  Follies (1971), Candide (1974), Sweeney Todd (1979), Evita (1979), The  Phantom of the Opera (1986), and Show Boat (1995).</p><p>Prince Albert National Park Park, central Saskatchewan, Canada.

One of the Maritime Provinces and Canada�s smallest province, it is an  island in the southern Gulf of St. Lawrence, separated from Nova Scotia  and New Brunswick by the Northumberland Strait. Its capital is Charlot�  tetown. Discovered by Jacques Cartier in 1534, it was used by Micmac  Indians for fishing and hunting. It was colonized by the French in 1720,  then ceded to the British in 1763. Known as the �Cradle of Confedera�  tion,� it was the site of the Charlottetown Conference of 1864, which led  to the federation of Canada. It became a province in 1873. It has good  natural harbours on its eastern and southern sides. There has been little  industrial development, and more than half of the island is used for agri�  culture. Fishing and tourism are also of economic importance. In 1997 a  bridge opened between Prince Edward Island and the mainland.</p><p>Prince of Wales Strait Narrow channel between Banks Island and  northwestern Victoria Island in the southwestern Arctic Archipeago of the  Northwest Territories, Canada.

It was named by the British captain George Vancouver in 1778 to  honour a son of George III. In 1989 one of the most disastrous oil spills  in history occurred when the tanker Exxon Valdez ran aground on Bligh  Reef and lost 10.9 million gallons of crude oil into the sound.</p><p>princeps Latin "first one," "leader" Unofficial title used by  Roman emperors from Augustus (r. 27 bc-ad 14) to Diocletian (r. 284-  305), a period called the principate. The title originated during the Roman  republic, when it was held by the leading member of the Senate. Its use  by Augustus strengthened his claim to be the restorer of republican insti�  tutions and virtues, though he and his successors were in fact autocrats.

April 28, 1918, Theresienstadt, Austria) Serbian nationalist and assassin  of Archduke Francis Ferdinand. A Bosnian Serb, he sought to unite the  southern Slavic peoples and destroy Austro-Hungarian rule in the Bal�  kans and was trained in terrorism by the Back Hand society. When the  Austro-Hungarian archduke made an official visit to Sarajevo in June  1914, Princip shot him and his wife, Sophie. The assassinations precipi�  tated World War I. Princip was sentenced to 20 years in prison, where he  died after the amputation of his arm.</p><p>Principe See Sao Tome and Principe</p><p>Pringle, Sir John (b.

As physician general to the  British armed forces (1740-48), he applied his knowledge to hospitals  and army camps. In Observations on the Diseases of the Army (1752), he  outlined procedures for hospital ventilation and camp sanitation. He rec�  ognized the various forms of dysentery as one, equated hospital and jail  fevers, and coined the term influenza. His suggestion that military hospi�  tals be respected as sanctuaries by both sides in a conflict led to the estab�  lishment of the Red Cross.</p><p>printed circuit Electrical device in which the wiring and certain com�  ponents consist of a thin coat of electrically conductive material applied  in a pattern on an insulating substrate. Printed circuits replaced conven�  tional wiring after World War II in much electronic equipment, greatly  reducing size and weight while improving reliability and uniformity over  the hand-soldered circuits formerly used. They are commonly used to  mount integrated circuits on boards for use as plug-in units in computers.</p><p>televisions, and other electronic devices. Mass-produced printed circuit  boards allow automated assembly of electronic components, considerably  reducing their cost.</p><p>printer, computer Electronic device that accepts text files or images  from a computer and transfers them to a medium such as paper or film.  It can be connected directly to the computer or indirectly via a network.  Printers are classified as impact printers (in which the print medium is  physically struck) and non-impact printers. Most impact printers are dot�  matrix printers, which have a number of pins on the print head that emerge  to form a character. Non-impact printers fall into three main categories:  laser printers use a laser beam to attract toner to an area of the paper;  ink-jet printers spray a jet of liquid ink; and thermal printers transfer wax-  based ink or use heated pins to directly imprint an image on specially  treated paper. Important printer characteristics include resolution (in dots  per inch), speed (in sheets of paper printed per minute), colour (full-colour  or black-and-white), and cache memory (which affects the speed at which  a file can be printed).</p><p>printing Process for reproducing text and illustrations, traditionally by  applying ink to paper under pressure, but today including various other  methods. In modern commercial printing, three basic techniques are used.  Letterpress printing relies on mechanical pressure to transfer a raised inked  image to the surface to be printed. Gravure printing transfers ink from  recessed cells of varying depths. In offset printing the printing and non�  printing areas of the plate differ not in height but in wettability.</p><p>printmaking Art form consisting of the production of images, usually  on paper but occasionally on fabric, parchment, plastic, or other support,  by various techniques of multiplication, under the direct supervision of  or by the hand of the artist. Such fine prints are considered original works  of art, even though they can exist in multiple copies. The major techniques  are relief printing, where the background is cut away, leaving a raised  image; intaglio printing, where the image is incised directly into the plate;  surface printing such as lithography, where the image is painted or drawn  onto a stone; and stencil printing, where the design is cut out and printed  by spraying paint or ink through the stencil. The history of printmaking  parallels the history of art and is one of the oldest art forms. Though he  had several predecessors, the first important engraver was a 15th-century  German, Martin Schongauer. In the 16th century Albrecht Durer created  prints of the highest quality, and in the 17th century the etchings of Rem�  brandt were especially fine. Japanese printmaking originated in the 17th  century with the ukiyo-e school of woodcuts; the best-known artists were  Hokusai and Hiroshige. Important 18th-century Western artists who made  prints include William Hogarth, Francisco Goya, and Giambattista Piranesi.  Among the works of 19th-century printmakers, those of Honore Daumier  and of many of the French Impressionists are notable. Experimentation in  new styles and new directions proliferated in the 20th century, with art�  ists from the century�s major movements�including Expressionism, Sur�  realism, Pop art, Minimalism, and Neo- Expressionism �all pursuing  printmaking.

An abnormal form of a normally  harmless protein found in mammals and birds, the disease-causing prion  can enter the brain through infection, or it can arise from a mutation in  the gene that encodes the protein. Once present in the brain it causes nor�  mal proteins to refold into the abnormal shape. As prion proteins multi�  ply, they accumulate within nerve cells, destroying them and eventually  causing brain tissue to become riddled with holes. Diseases caused by  prions include Creutzfeldt-Jakob disease, mad cow disease, and scrapie. Pri�  ons are unlike all other known disease-causing organisms in that they  appear to lack nucleic acid (DNA or RNA).</p><p>Pripet Vpri-.peA Marshes Vast marsh region, southern Belarus and  northwestern Ukraine.

He used the writings of Apollonius  Dyscolus on Greek grammar as a guide in producing his own classic works  on Latin grammar. His Institutiones grammaticae (�Grammatical Foun�  dations�), with citations from Latin authors, became the standard work  for teaching grammar in the Middle Ages. His other writings include trea�  tises on weights and measures and on the metres of Terence.</p><p>prism Piece of glass or other transparent material cut with precise angles  and plane faces. Prisms are useful for analyzing and refracting light (see  refraction). A triangular prism can separate white light into its constitu�  ent colours by refracting each different wavelength of light by a different  amount. The longer wavelengths (those at the red end of the spectrum) are  bent the least, the shorter ones (those at the violet end) the most. The  result is the spectrum of visible light, or the rainbow. Prisms are used in  certain kinds of spectroscopy and in various optical systems.</p><p>prison Institution for the confinement of people convicted of crimes.  Prisons are administered by state, provincial, or national governments and  house inmates for relatively long terms. They thus differ from jails, which  usually are under local jurisidiction and house inmates serving short sen�  tences. Until the late 18th century, prisons were used mainly for the con�  finement of debtors who could not meet their obligations, of accused  persons waiting to be tried, and of convicts who were waiting for their  sentences of death or banishment to be put into effect. Later, imprison�  ment itself came to be accepted as a means of punishing convicted crimi�  nals. In early U.S. prisons, prisoners were kept in isolation; in the 19th  century, they were permitted to work together, but only in silence. At the  end of the 19th century, prison reformers successfully advocated segre�  gation of criminals by type of crime, age, and sex; rewards for good  behaviour; indeterminate sentencing; vocational training; and parole. In  the late 20th century, prison populations in many countries began to  explode as arrests for violent offenses and for possession of small amounts  of illegal drugs increased.</p><p>prisoner's dilemma Imaginary situation employed in game theory.  One version is as follows. Two prisoners are accused of a crime. If one  confesses and the other does not, the one who confesses will be released  immediately and the other will spend 20 years in prison. If neither con�  fesses, each will be held only a few months. If both confess, they will  each be jailed 15 years. They cannot communicate with one another.  Given that neither prisoner knows whether the other has confessed, it is  in the self-interest of each to confess himself. Paradoxically, when each  prisoner pursues his self-interest, both end up worse off than they would  have been had they acted otherwise.

After unifying Nepal, he  annexed territory in northern India, as well as large portions of the Pla�  teau of Tibet and of the valleys of the Inner Himalayas. He sealed Nepal�s  border and maintained peaceful but distant relations with the British.</p><p>Pritzker Architecture Prize World�s most prestigious honour in the  field of architecture. Established through the philanthropic efforts of the  Pritzkers, a prominent Chicago business family, the prize, first awarded  in 1979, bestows an annual award of $100,000 on an architect whose built  contributions to the field and to society are judged worthiest. The inter�  national jury has included architects, artists, historians, academicians, crit�  ics, and business executives.</p><p>privacy, right of Right of a person to be free from intrusion into mat�  ters of a personal nature. Although not explicitly mentioned in the U.S.  Constitution, a right to privacy has been held to be implicit in the Bill of  Rights, providing protection from unwarranted government intrusion into  areas such as marriage and contraception. A person�s right to privacy may  be overcome by a compelling state interest. In tort law, privacy is a right  not to have one�s intimate life and affairs exposed to public view or oth�  erwise invaded. Less broad protections of privacy are afforded public  officials and others defined by law as �public figures� (e.g., movie stars).</p><p>privateer Privately owned vessel commissioned by a state at war to  attack enemy ships, usually merchant vessels. All nations engaged in pri�  vateering from the earliest times until the 19th century. Crews were not  paid by the government but were entitled to receive portions of the value  of any cargo they seized. Limiting privateers to the activities laid down  in their commissions was difficult, and the line between privateering and  piracy was often blurred. In 1856, by the Declaration of Paris, Britain and  other major European countries (except Spain) declared privateering ille�  gal; the U.S. finally repudiated it at the end of the 19th century, and Spain  agreed to the ban in 1908. See also buccaneer, Francis Drake, William Kidd,  Jean Laffite.</p><p>privatization Transfer of government services or assets to the private  sector. State-owned assets may be sold to private owners, or statutory  restrictions on competition between privately and publicly owned enter�  prises may be lifted. Services formerly provided by government may be  contracted out. The objective is often to increase government efficiency;  implementation may affect government revenue either positively or nega�  tively. Privatization is the opposite of nationalization, a policy resorted to  by governments that want to keep the revenues from major industries,  especially those that might otherwise be controlled by foreign interests.</p><p>privet Vpri-V9t\ Any of about 40-50 species of shrubs and small trees  in the genus Ligustrum of the olive family that are widely used for hedges,  screens, and ornamental plantings. Native to Europe, Asia, Australia, and  the Mediterranean, these evergreen or deciduous plants have usually oval,  smooth-edged leaves; creamy-white, often odorous clusters of flowers;  and black berries. The hardy common privet (L. vulgare), native to north�  eastern Europe and Britain and naturalized in northeastern North America,  is used widely as a hedge plant. Mock privets belong to the genus  Phillyrea (same family) and bear small, bright-red fruits that turn purple-  black as they mature.</p><p>privileged communication or confidential communication</p><p>In law, communication between parties to a confidential relation such that  the communication�s recipient is exempted from disclosing it as a wit�  ness. Communications between attorney and client are privileged and do  not have to be disclosed to the court. The right to privileged communi�  cation also exists between husbands and wives, as neither is required to  testify against the other in court, and between physicians and patients,  though doctors may be required to disclose such information if the right  of the defendant to receive a fair trial outweighs the patient�s right to con�  fidentiality. Members of the clergy have limited rights to refuse to testify  in court, and reporters have been accorded a limited right to privileged  communication concerning the sources of their information, though they  can be ordered to divulge information in certain circumstances.</p><p>Privy Vpri-ve\ Council Historically, the British sovereign�s private  council. Once powerful, the Privy Council has long ceased to be an active  body, having lost most of its judicial and political functions since the  middle of the 17th century. It grew out of the medieval curia ( curia regis ),  which comprised the king�s tenants in chief, household officials, and other  advisers. The curia performed all the functions of government in either  small groups, which became the king�s council, or large groups, which  grew into the great council and Parliament. It now is chiefly concerned  with issuing royal charters, conducting government research, and serving  as an appeals body for ecclesiastical and other lesser courts.

First established in 1666  by Louis XIV and Charles Le Brun, it enables young French painters, sculp�  tors, architects, engravers, and musicians to study in Rome. Grand-prize  winners in each artistic category study at the Academie de France in Rome  for four years. Many of the greatest French artists and musicians of past  centuries have been prizewinners, including Jean-Honore Fragonard,  Jacques-Louis David, Hector Berlioz, and Claude Debussy. The prizes are still  being awarded, though their prestige has diminished.</p><p>prize cases (1863) Legal dispute in which the U.S. Supreme Court  upheld Pres. Abraham Lincoln�s seizure of ships (prizes). In April 1861,  three months before Congress declared a state of war, Lincoln authorized  a blockade of Confederate ports. In that three-month period, several mer�  chant ships ran the blockade and were captured by the Union navy. The  legality of the seizures was challenged in court; on appeal, the Supreme  Court ruled that the president had acted legally to resist insurrection,  sanctioning presidential use of emergency powers.</p><p>probability theory Branch of mathematics that deals with analysis  of random events. Probability is the numerical assessment of likelihood on  a scale from 0 (impossibility) to 1 (absolute certainty). Probability is usu�  ally expressed as the ratio between the number of ways an event can hap�  pen and the total number of things that can happen (e.g., there are 13  ways of picking a diamond from a deck of 52 cards, so the probability of  picking a diamond is 13 /s 2 , or Va). Probability theory grew out of attempts  to understand card games and gambling. As science became more rigor�  ous, analogies between certain biological, physical, and social phenom�  ena and games of chance became more evident (e.g., the sexes of newborn  infants follow sequences similar to those of coin tosses). As a result,  probability became a fundamental tool of modern genetics and many other  disciplines. Probability theory is also the basis of the insurance industry,  in the form of actuarial statistics.</p><p>probate In law, the process of proving in a court (probate court) that  an instrument is the valid last will and testament of a deceased person.  The term also refers broadly to the process of administering an estate.  Unless it is contested or shown to contain obvious anomalies, a document  purporting to be a will requires little authenticating proof for certification  (admission to probate). Probate courts also often supervise the adminis�  tration of estates by executors and oversee the guardianship of minors  and others lacking capacity under the law.</p><p>probation Conditional suspension of an offender�s sentence upon the  promise of good behaviour and agreement to accept supervision and abide  by specified requirements. It differs from parole in that the offender is not  required to serve any of his sentence. Those convicted of serious offenses  and those previously convicted of other offenses are usually not consid�  ered for probation. Studies in several countries show that 70 to 80% of  probationers successfully complete their probation; additional limited evi�  dence suggests that recidivism may be less than 30%.</p><p>problem play or thesis play Type of drama that developed in the  19th century to deal with controversial social issues in a realistic manner,  expose social ills, and stimulate thought and discussion. It is exemplified  by the works of Henrik Ibsen, who exposed hypocrisy, greed, and hidden  coiTuption of society in a number of masterly plays. His influence encour�  aged others to use the form. George Bernard Shaw brought it to an intel�  lectual peak with his plays and their long, witty prefaces. More recent  examples include works of Sean O'Casey, Athol Fugard, Arthur Miller, and  August Wilson.</p><p>problem solving Process involved in finding a solution to a problem.  Many animals routinely solve problems of locomotion, food finding, and  shelter through trial and error. Some higher animals, such as apes and  cetaceans, have demonstrated more complex problem-solving abilities,  including discrimination of abstract stimuli, rule learning, and application  of language or languagelike operations. Humans use not only trial and  error but also insight based on an understanding of principles, inductive  and deductive reasoning (see deduction; induction; and logic), and diver�  gent or creative thinking (see creativity). Problem-solving abilities and  styles may vary considerably by individual.</p><p>proboscis monkey Xprs-'ba-sos, pro-'bas-kosV Species (Nasalis lar-  vatus, family Cercopithecidae) of long-tailed arboreal Old World monkey  of swampy mangrove forests on Borneo.

The male�s nose is long and pendulous, the  female�s is smaller, and the young�s is upturned. Males are 22-28 in.  (56-72 cm) long, have a 26-29-in. (66-75-cm) tail, and weigh 26-53 lbs  (12-24 kg); females are smaller and much lighter.</p><p>procedural law Law that prescribes the procedures and methods for  enforcing rights and duties and for obtaining redress (e.g., in a suit). It is  distinguished from substantive law (i.e., law that creates, defines, or regu�  lates rights and duties). Procedural law is a set of established forms for  conducting a trial and regulating the events that precede and follow it. It  prescribes rules relative to jurisdiction, pleading and practice, jury selec�  tion, evidence, appeal, execution of judgments, representation of counsel,  costs, registration (e.g., of a stock offer), prosecution of crime, and con�  veyancing (transference of deeds, leases, etc.), among other matters.</p><p>process philosophy 20th-century school of philosophy that empha�  sizes the elements of becoming, change, and novelty in experienced real�  ity and opposes the traditional Western philosophical stress on being,  permanence, and uniformity. Reality, including both the natural world and  the human sphere, is essentially historical in this view, emerging from  (and bearing) a past and advancing into a novel future. Hence, it cannot  be grasped by old static spatial concepts that ignore the temporal and  novel aspects of the universe given in human experience. The foremost  contributors to process philosophy have been Henri Bergson and Alfred  North Whitehead.</p><p>Proclamation of 1763 Proclamation by Britain at the end of the  French and Indian War that prohibited settlement by whites on Indian ter�  ritory. It established a British-administered reservation from west of the  Appalachians and south of Hudson Bay to the Floridas and ordered white  settlers to withdraw. It formalized Indian land titles and forbade land pat�  ents without a purchase from, or treaty agreement with, the title-holding  tribe. After American colonists and pioneers objected, the proclamation  was replaced by the Treaties of Fort Stanwix.</p><p>proconsul In the ancient Roman republic, a consul whose powers had  been extended for a definite period beyond his regular one-year term.  These extensions were necessitated by such events as long periods of war.  The extension of a chief magistrate�s term was originally voted by the  people, but the power was soon assumed by the Senate. Provincial gov�  ernors were usually magistrates whose terms had been extended. Under  the empire (after 27 bc), governors of senatorial provinces were called  proconsuls.</p><p>Procopius \pr3-'ko-pe-3s\ (b. probably between 490 and 507, Caesarea,  Palestine) Byzantine historian. He advised Belisarius on his first Persian  campaign (527-531) and fought the Vandals in Africa until 536. He was  in Sicily with Belisarius and fought the Goths in Italy until 540, and he  described the plague in Constantinople in 542. His books Polemon  (�Wars�), Peri Ktismaton (�Buildings�), and Anecdota (�Secret History�)  are valuable sources for his period�s history.</p><p>Procter, William (Cooper) (b. Aug. 25, 1862, Glendale, near Cin�  cinnati, Ohio, U.S.�d. May 2, 1934, Cincinnati) U.S. manufacturer. A  grandson of the founder of Procter &amp; Gamble Co., he started working at  the company in 1883. He served as president from 1907 to 1930, during  which time sales rose from $20 million to over $200 million. Under his  leadership the company pioneered in labour relations: he introduced a  profit-sharing plan for employees (1887), guaranteed them 48 weeks of  work a year (1920), and introduced a disability pension plan, a life-  insurance plan, and employee representation on the board of directors.</p><p>Procter &amp; Gamble Co, Major U.S. manufacturer of soaps, cleansers,  and other household products. It was formed in 1837 when William C.  Procter, a British candlemaker, and James Gamble, an Irish soapmaker,  merged their businesses in Cincinnati. The company supplied soap and  candles to the Union Army in the Civil War and continued to prosper when  the war was over. Among its products were Ivory soap (1879), Crisco  shortening (1911), Tide, the first synthetic laundry detergent (1946), and  Joy, the first liquid synthetic detergent (1949). In 1932 Procter &amp; Gamble  also sponsored the first radio soap opera. The company later began to  make personal-care items such as toothpaste, shampoo, and deodorant;  food products such as cake mixes and coffee; and miscellaneous products  such as cellulose pulp and chemicals.</p><p>proctoscope \'prak-t9-,skop\ Lighted tube used to inspect the rectum  and lower colon.

Aug. 9, 1939, Scandiano, Italy) Italian prime min�  ister (1996-98) and president of the European Commission (1999-2004),  one of the governing bodies of the European Union (EU). Prodi graduated  from Catholic University in Milan in 1961 and did postdoctoral work at  the London School of Economics. After serving as a professor of eco�  nomics at the University of Bologna, he entered government as minister  of industry in 1978. In 1996, after two productive stints as chairman of  the Institute for Industrial Reconstruction (1982-89 and 1993-94), he was  narrowly elected prime minister as head of the centre-left Olive Tree coa�  lition. During his 28 months in office, Prodi privatized telecommunica�  tions and reformed the government�s employment and pension policies.  Budget disputes with members of his own party led to his resignation in  October 1998. During his five-year term as president of the European  Commission, the EU expanded beyond its western European roots to  include Malta, Cyprus, and eight eastern and central European members.</p><p>producer goods or capital goods or intermediate goods</p><p>Goods manufactured and used in further manufacturing, processing, or  resale. Intermediate goods either become part of the final product or lose  their distinct identity in the manufacturing stream, while capital goods are  the plant, equipment, and inventories used to produce final products. The  contribution of intermediate goods to a country�s gross domestic product  may be determined through the value-added method, which calculates the  amount of value added to the final consumer good at each stage of pro�  duction. This series of values is summed to estimate the total value of the  final product.</p><p>product rule Rule for finding the derivative of a product of two func�  tions. If both/and g are differentiable, then (fg)' =fg' +f'g-</p><p>production function Equation that expresses the relationship between  the quantities of productive factors (such as labour and capital) used and  the amount of product obtained. It states the amount of product that can  be obtained from every combination of factors, assuming that the most  efficient available methods of production are used. The production func�  tion can thus measure the marginal productivity of a particular factor of  production and determine the cheapest combination of productive factors  that can be used to produce a given output.</p><p>production management or operations management Plan�  ning, implementation, and control of industrial production processes to  ensure smooth and efficient operation. Production management techniques  are used in both manufacturing and service industries. Production man�  agement responsibilities include the traditional �five M�s�: men and  women, machines, methods, materials, and money. Managers are  expected to maintain an efficient production process with a workforce that  can readily adapt to new equipment and schedules. They may use indus�  trial engineering methods, such as time-and-motion studies, to design effi�  cient work methods. They are responsible for managing both physical  (raw) materials and information materials (paperwork or electronic docu�  mentation). Of their duties involving money, inventory control is the most  important. This involves tracking all component parts, work in process,  finished goods, packaging materials, and general supplies. The produc�  tion cycle requires that sales, financial, engineering, and planning depart�  ments exchange information�such as sales forecasts, inventory levels,  and budgets�until detailed production orders are dispatched by a  production-control division. Managers must also monitor operations to  ensure that planned output levels, cost levels, and quality objectives are  met. See also productivity.</p><p>productivity In economics, a measure of productive efficiency calcu�  lated as the ratio of what is produced to what is required to produce it.  Any of the traditional factors of production� land, labour, or capital �can  be used as the denominator of the ratio, though productivity calculations  are actually seldom made for land or capital since their capacity is dif�  ficult to measure. Labour is in most cases easily quantified�for example,  by counting workers engaged on a particular product. In industrialized  nations, the effects of increasing productivity are most apparent in the use  of labour. Productivity can be seen not only as a measure of efficiency but  also as an indicator of economic development. Productivity increases as a  primitive extractive economy develops into a technologically sophisti�  cated one. The pattern of increase typically exhibits long-term stability</p><p>interrupted by sudden leaps that represent major technological advances.  Productivity in Europe and the U.S. made great strides following the  development of such technologies as steam power, the railroad, and the  gasoline motor. Later in the 20th century, advances in productivity  stemmed from a number of innovations, including assembly lines and auto�  mation, COMPUTER-INTEGRATED MANUFACTURING, DATABASE MANAGEMENT SYSTEMS,  just-in-time manufacturing, and just-in-time inventory management.  Increases in productivity have tended to lead to long-term increases in  real wages.</p><p>proenzyme See zymogen</p><p>profiler Machine tool for cutting complex, irregular shapes, invented by  Frederick W. Howe. A rapidly rotating cutter is guided by a finger that  traces around the outline of a pattern. The profiler was an important com�  ponent of the American System of manufacture that made mass production  possible.</p><p>profit In business usage, the excess of total revenue over total cost dur�  ing a specific period of time. In economics, profit is the excess over the  returns to capital, land, and labour. Since these resources are measured by  their opportunity costs, economic profit can be negative. There are vari�  ous sources of profit: an innovator who introduces a new production tech�  nique can earn entrepreneurial profits; changes in consumer tastes may  bring some firms windfall profits; or a firm may restrict output to prevent  prices from falling to the level of costs (monopoly profit).</p><p>profit sharing System by which employees are paid a share of the  profits of the business enterprise in which they are employed, in keeping  with a plan outlined in advance. These payments, which may vary accord�  ing to salary or wage, are in addition to regular earnings. Profit-sharing  plans were probably first developed in France in the early 19th century  as worker incentives. Today such plans are used by businesses in West�  ern Europe, the U.S., and parts of Latin America. Profit shares may be  distributed on a current or deferred basis or through some combination  of the two. Under current distribution, profits are paid out to employees  immediately in the form of cash or company stock. In deferred-payment  plans, profit shares may be paid into a trust fund from which employees  can draw annuities in later years.</p><p>progeria \pro-'jir-e-3\ Disorder with characteristics of premature aging.  Affected persons have thin skin, go bald or gray early, and develop dis�  eases of aging decades earlier than normal individuals. Not all systems  are affected; there is no senility, no aging in the central nervous system.  There are two major types. In the extremely rare Hutchinson-Gilford syn�  drome, children look 60 years old by age 10 and die at an average age of  13. The unrelated Werner syndrome is a recessive hereditary disease that  begins in young adulthood and makes patients look 30 years older than  they are; their average life span is 47 years.</p><p>progesterone \pro-'jes-t9-,ron\ Steroid hormone secreted by the female  reproductive system that functions mainly to regulate the condition of the  endometrium (see uterus), preparing it to accept a fertilized egg. If the egg  is not fertilized, the level of progesterone drops, the uterine lining breaks  down, and menstruation ensues. If the egg is fertilized (see pregnancy), the  placenta produces progesterone, whose effects include preparing the mam�  mary glands for lactation. Many forms of oral contraception use a syn�  thetic progesterone.</p><p>program, computer Set of ordered instructions that enable a com�  puter to carry out a specific task. A program is prepared by first formu�  lating the task and then expressing it in an appropriate programming  language. Programmers may work in machine language or in assembly lan�  guages. But most applications programmers use one of the high-level lan�  guages (such as BASIC or C++) or fourth-generation languages that more  closely resemble human communication. Other programs then translate  the instructions into machine language for the computer to use. Programs  are stored on permanent media (such as a hard disk), and loaded into RAM  to be executed by the computer�s processor, which executes each instruc�  tion in the program, one at a time. Programs are often divided into appli�  cations and system programs. Applications perform tasks such as word  processing, database functions, or accessing the Internet. System programs  control the functioning of the computer itself; an operating system is a very  large program that controls the operations of the computer, the transfer  of files, and the processing of other programs.</p><p>programming language Language in which a computer program�  mer writes instructions for a computer to execute. Some languages, such</p><p>� 2006 Encyclopaedia Britannica, Inc.</p></section><section><p>1552 I Progressive Conservative Party of Canada &#x25BA; proletariat</p><p>as COBOL, FORTRAN, Pascal, and C, are known as procedural languages  because they use a sequence of commands to specify how the machine is  to solve a problem. Others, such as LISP, are functional, in that program�  ming is done by invoking procedures (sections of code executed within a  program). Languages that support object-oriented programming take the  data to be manipulated as their point of departure. Programming languages  can also be classified as high-level or low-level. Low-level languages  address the computer in a way that it can understand directly, but they are  very far from human language. High-level languages deal in concepts that  humans devise and can understand, but they must be translated by means  of a compiler into language the computer understands.</p><p>Progressive Conservative Party of Canada Former Canadian  political party. It was formed as the Liberal-Conservative Party in 1854  from a union of conservative and moderate-liberal political factions;  except for a period during and after World War I, the party kept this name  until 1942, when it adopted the name Progressive Conservative Party of  Canada. Its first leader was John Macdonald. The party led the govern�  ment from 1854 to 1873 and again from 1878 to 1896. It regained power  in coalition with the Quebec nationalists in 1911 but went down to severe  defeat in 1921. From then until 1957 the party held power only twice,  briefly in 1926 and from 1930 to 1935. The party held power from 1958  to 1963 under John G. Diefenbaker, from 1979 to 1980 under Joe Clark,  and from 1984 to 1989 under Brian Mulroney. In 1993 it was reduced to  only two seats in the Canadian House of Commons. In 2003 the Progres�  sive Conservative Party merged with the Canadian Alliance to form the  Conservative Party of Canada. The party favoured reducing government  intervention in both the economy and social affairs; strongly federalist, it  also was less accommodating than other parties to Quebec separatism.</p><p>progressive education Movement that took form in Europe and  North America during the late 19th century as a reaction to the alleged  narrowness and formalism of traditional education. A main objective was  to educate the �whole child��that is, to attend to physical and emotional  as well as intellectual growth. Creative and manual arts gained impor�  tance in the curriculum, and children were encouraged toward experi�  mentation and independent thinking. Progressive educational ideas and  practices were most powerfully advanced in the U.S. by John Dewey. See  also SuMMERHILL SCHOOL.</p><p>Progressive Party U.S. independent political party. The first Progres�  sive Party, known as the Bull Moose Party, was organized in 1911. The  second was assembled in 1924; it nominated as its presidential candidate  Robert La Follette, who received 17% of the national vote on a platform  calling for a �housecleaning� of executive departments, public control of  natural resources, public ownership of the railways, and tax reduction.  The party dissolved upon La Follette�s death in 1925. The third Progres�  sive Party, founded in 1947 by Henry Wallace, differed from the previous  groups in its focus on foreign affairs; it favoured a conciliatory policy  toward the Soviet Union. Though Wallace received more than one mil�  lion votes in the 1948 election, the party was never again influential.</p><p>progressive tax Tax levied at a rate that increases as the quantity  subject to taxation increases. Designed to collect a greater proportion of  tax revenue from wealthy people, progressive taxes reflect the view that  those who are able to pay more should carry a heavier share of the tax  burden. Progressive income taxes may provide for exemption from tax  liability for incomes under a specified amount, or they may establish pro�  gressively greater rates for larger and larger incomes. The presence of  deductions can also make a tax progressive. Progressive taxes are a sta�  bilizing force in periods of inflation or recession because the amount of  tax revenue changes more than proportionately with an increase or  decrease in income. For example, in an inflationary economy, as prices  and incomes rise, a greater percentage of taxpayers� income goes toward  taxes. Government revenues increase, and the government has more lever�  age over the economy. A side effect of this system is that lower-income  taxpayers have an especially difficult time making ends meet when infla�  tion is high. To compensate, many economists advocate indexation; sev�  eral countries adjust their tax rates annually in times of inflation, usually  in line with the consumer price index. See also regressive tax.</p><p>Prohibition Legal prevention of the manufacture, sale, or transporta�  tion of alcoholic beverages. In the U.S., the Prohibition movement arose  out of the religious revivalism of the 1820s. Maine passed the first state  Prohibition law in 1846, ushering in a wave of such state legislation. The  drive toward national Prohibition was fueled by the Anti-Saloon League,</p><p>founded in 1893. With Prohibition already adopted in 33 states, the 18th  Amendment to the U.S. Constitution went into effect in 1920. Prohibition  was embraced with varying degrees of enthusiasm in different parts of the  country, and enforced accordingly. In urban areas, bootlegging gave rise  to organized crime, with such gangsters as Al Capone. In part because of  the rise in crime, its supporters gradually became disenchanted with it.  The 21st Amendment repealed the 18th in 1933, and by 1966 all states  had also abandoned Prohibition.</p><p>Prohibition Party Oldest minor U.S. political party still in existence.  It was founded in 1869 to campaign for legislation to prohibit the manu�  facture and sale of liquor. The party was strong in rural regions and among  small-town voters affiliated with Protestant evangelical churches. It nomi�  nated candidates for state and local offices and attained national strength  in the 1888 and 1892 presidential elections, when its candidates polled  2.2% of the vote. Since 1900 it has been active mainly on local levels.</p><p>projective geometry Branch of mathematics that deals with the rela�  tionships between geometric figures and the images (mappings) of them  that result from projection. Examples of projections include motion pic�  tures, maps of the Earth�s surface, and shadows cast by objects. One  stimulus for the subject�s development was the need to understand per�  spective in drawing and painting. Every point of the projected object and  the corresponding point of its image must lie on the projection ray, a line  that passes through the centre of projection. Modem projective geometry  emphasizes the mathematical properties (such as straightness of lines and  points of intersection) preserved in projections despite the distortion of  lengths, angles, and shapes.</p><p>prokaryote \pro-'kar-e-,ot\ Any cellular organism that lacks a distinct  nucleus. Bacteria (including blue-green algae, or cyanobacteria) are  prokaryotes; all other organisms are eukaryotes. Prokaryotic cells lack a  nuclear membrane and most of the components of eukaryotic cells. The  cytoplasm includes ribosomes that carry out protein synthesis and a  double-stranded DNA chromosome, usually circular. Many prokaryotes  also contain additional circular DNA molecules called plasmids. The fla�  gella are distinct from those of eukaryotes in design and movement.</p><p>Prokofiev \pr3-'k6-fyif\, Sergey (Sergeyevich) (b. April 23,1891,  Sontsovka, Ukraine, Russian Empire�d. March 5, 1953, Moscow, Rus�  sia, U.S.S.R.) Russian composer and pianist. Son of a pianist, he began  writing piano pieces at age five and wrote an opera at nine. He studied at  the St. Petersburg Conservatory (1904-14) with Nikolay Rimsky-Korsakov  and others. Prolific and arrogant, from 1910 he made a living by perform�  ing as a virtuoso. He played his own first concerto at his graduation recital.  During World War I he wrote his Scythian Suite (1915) and First (�Clas�  sical�) Symphony (1917). His opera The Love for Three Oranges pre�  miered in 1921 in Chicago. Paris was his base from 1922, and during the  1920s he produced three new symphonies and the operas The Fiery Angel  (1927) and The Gambler (1928). In the 1930s he was drawn back to his  homeland; there he wrote the score for the ballet Romeo and Juliet (1936),  the symphonic children�s tale Peter and the Wolf (1936), and striking  national music for Sergey Eisenstein�s film Alexander Nevsky (1938). World  War II inspired the score to Eisenstein�s Ivan the Terrible (1942�45) and  the opera War and Peace (1943). The government�s denunciation of his  work in 1948 was a harsh blow; his health failed, and he died on the same  day as Joseph Stalin.</p><p>prolapse Protrusion of an internal organ out of its normal place, usu�  ally of the rectum or uterus outside the body when supporting muscles  weaken. The membrane lining the rectum can push out through the anus,  most often in old people with constipation who strain during defecation.  Chronic rectal prolapse requires surgical repair. The uterus may prolapse  into the vagina after gravity adds to weakness from childbirth injuries.  Temporary supports and pelvic exercises can relieve mild uterine pro�  lapse, but severe prolapse may require hysterectomy.</p><p>proletariat \,pro-b-'ter-e-3t\ The lowest, or one among the lowest,  economic and social classes in a society. In ancient Rome, the proletariat  were poor landless freemen who, crowded out of the labour market by the  extension of slavery, became parasites on the economy. Karl Marx used  the term to refer to the class of wage earners engaged in industrial pro�  duction only (the broader term working class included all those obliged  to work for a living). Another of Marx�s categories, the lumpenproletar-  iat (lumpen meaning �rags�), comprised marginal and unemployable  workers, paupers, beggars, and criminals. Marxian theory predicted a  transitional phase between the abolition of capitalism and the establish-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>proline &#x25BA; property tax I 1553</p><p>ment of communism during which a �dictatorship of the proletariat�  would suppress resistance to the socialist revolution by the bourgeoisie,  destroy the social relations of production underlying the class system, and  create a new, classless society.</p><p>proline \'pro- l len\ One of the nonessential amino acids, found in many  proteins, especially collagen. Because the nitrogen atom of its amino group  is part of a ring structure (making it a heterocyclic compound), its chemi�  cal properties differ from those of the other amino acids in proteins. It is  used in biochemical, nutritional, and microbiological research and as a  dietary supplement.</p><p>promenade V.pra-mo-'nad, .pra-mo-'nadX Public place where people  walk (or, in the past, rode) at leisure for pleasure, exercise, or display.  Promenades are pedestrian avenues pleasingly landscaped or command�  ing a view, often located along waterfronts and in parks. Vehicular traffic  may or may not be restricted.</p><p>Prometheus Xpra-'me-the-osV In Greek religion, one of the Titans and a  god of fire. He was a master craftsman and a supreme trickster, and he  was sometimes associated with the creation of humans. According to leg�  end, Prometheus stole fire from the gods and gave it to humans. In ven�  geance, Zeus created Pandora, who married Prometheus�s brother and set  loose all the evils of the world. Another tale held that Zeus had Prometheus  chained to a mountain and sent an eagle to devour his liver, which regen�  erated every night so that he could suffer the same torment the next day.</p><p>promissory note Short-term credit instrument consisting of a written  promise by one person to pay a specified amount of money to another on  demand or at a given future date. Promissory notes were in use in Europe  as early as the Renaissance. They are often negotiable and may be secured  by the pledge of collateral. The instrument changed substantially during  the 20th century, when various clauses were added regarding payment and  other provisions�for example, authorizing the sale of collateral, permit�  ting extensions of time, and allowing acceleration of payment in the event  of default. See also bill of exchange.</p><p>Promoters Revolution (1932) Bloodless coup that put an end to  absolute monarchy in Siam (Thailand) and initiated the Constitutional  Era. The coup was headed by the Promoters, a group that included mem�  bers of the Thai elite, noted intellectuals, and disaffected army officers.  Their first constitution, the Temporary Constitution, stripped the king of  power and put it in the hands of the Promoters themselves. The Perma�  nent, or December, Constitution restored some of the royal prestige and  dignity and introduced some liberal, Western-style reforms. None of Thai�  land�s subsequent constitutions effectively limited political power or pro�  vided a means by which political contests could be decided. See also  Luang Phibunsongkhram; Pridi Phanomyong.</p><p>pronghorn Ruminant (Antilocapra americana) of North American  plains and semideserts, the only liv�  ing member of the family Antiloca-  pridae. The pronghorn stands 30-40  in. (80-100 cm) tall. It is reddish  brown with a short, dark-brown  mane, white underparts, two white  bands on the throat, and a circular  white patch on the rump. Both sexes  bear erect, two-pronged horns; the  longer prong curves backward, the  shorter prong forward. Pronghorns  live alone or in small bands in sum�  mer, and in large herds in winter. The  fastest mammal of North America,  the pronghorn can run 45 mph (70  kph) and can bound up to 20 ft (6 m). Though tens of millions once  roamed the West, they were nearly exterminated by hunters in the early  20th century; conservation efforts have since allowed their populations to  increase.</p><p>proof In logic and mathematics, an argument that establishes a propo�  sition�s validity. Formally, it is a finite sequence of formulas generated  according to accepted rules. Each formula either is an axiom or is derived  from a previously established theorem, and the last formula is the state�  ment that is to be proven. The essence of deductive reasoning (see deduc�  tion), this is the basis of Euclidean geometry and all scientific methods  inspired by it. An alternative form of proof, called mathematical induc�</p><p>tion, applies to propositions defined through processes based on the count�  ing numbers. If the proposition holds for n = 1 and can be shown to hold  for n = k + 1 whenever n = k (a constant) is also true, then it holds for all  values of n. An example is the assertion that the sum of the first n count�  ing numbers is n(n + l)/2.</p><p>propaganda Manipulation of information to influence public opinion.  The term comes from Congregatio de Propaganda Fide (Congregation for  the Propagation of the Faith), a missionary organization established by  the pope in 1622. Propagandists emphasize the elements of information  that support their position and deemphasize or exclude those that do not.  Misleading statements and even lies may be used to create the desired  effect in the public audience. Lobbying, advertising, and missionary activ�  ity are all forms of propaganda, but the term is most commonly used in  the political arena. Prior to the 20th century, pictures and the written media  were the principal instruments of propaganda; radio, television, motion  pictures, and the Internet later joined their ranks. Authoritarian and totali�  tarian regimes use propaganda to win and keep the support of the popu�  lace. In wartime, propaganda directed by a country at its own civilian  population and military forces can boost morale; propaganda aimed at the  enemy is an element of psychological warfare.</p><p>propane Colourless, easily liquefied hydrocarbon gas (C 3 H 8 or, more  fully, CH 3 CH 2 CH 3 ). Separated in large quantities from natural gas, light  crude oil, and oil-refinery gases, it is available as liquefied propane or as  a major constituent of liquefied petroleum gas (LPG). It is an important  raw material for the manufacture of ethylene and for the petrochemical  industry. It is also used as a refrigerant, extractant, solvent, aerosol pro�  pellant, and fuel for portable cooking appliances, torches, and lighters.</p><p>propeller Device with a central hub and radiating blades placed so that  each forms part of a helical (spiral) surface, used to propel a vehicle such  as a ship or airplane. By its rotation in water or air, the propeller produces  thrust on the blades, which gives forward motion to the vehicle.</p><p>proper motion Apparent motion of a star across the celestial sphere at  right angles to the observer�s line of sight, generally measured in seconds  of arc per year. Any radial motion (toward or away from the observer) is  not included. Edmond Halley was the first to detect proper motions; the  largest known is that of Barnard's star, about 10 seconds yearly.</p><p>Propertius Xpro-'por-shos, pro-'por-she-asV, Sextus (b. 55/43, Assisi,  Umbria�d. after 16 bc, Rome) Roman poet. Very few details of his life  are known. The first and best known of his four books of elegies (see  elegy), Cynthia, was published in 29 bc, the year he met its heroine (his  mistress, whose real name was Hostia). She emerges from his poems as  beautiful, uninhibited, jealous, and irresistible. In Book II his main theme  is still love, but he also contemplates writing an epic, is preoccupied with  thoughts of death, and attacks the materialism of his time. Books III and  IV demonstrate a bold command of language and various literary forms;  among the subjects are Roman mythology and history.</p><p>property In law, something that is owned or possessed. Concepts of  property vary widely among cultures. In the West, property is generally  regarded as either tangible (e.g., land or goods) or intangible (e.g., stocks  and bonds or a patent). Individual ownership of property is emphasized in  Western societies, whereas in many non-Western societies property own�  ership is deemphasized or conceived on a more strictly communal basis.  The use of property is extensively regulated throughout the West. Land-  owners injured by adjoining land uses may sue in nuisance in Anglo-  American countries; similar actions exist in civil-law countries. Throughout  the West, landowners may agree to allow others to use their land in ways  that would otherwise be actionable, and such agreements may be made to  bind those to whom the land is conveyed. Anglo-American law tends to  divide these grants of use rights into categories that reflect their common-  law origins: easements (such as rights of way), profits (such as the right to  take minerals or timber), real covenants (such as a promise to pay a home-  owners� association fee), and equitable servitudes (such as a promise to use  the property for residential purposes only). The civil law has fewer catego�  ries, the general category �servitudes� tending to cover for them all, and is  a bit more restrictive. A common means of acquiring property is by transfer  from the previous owner or owners. Such transfers include sales, dona�  tions, and inheritance. See also adverse possession; community property; intel�  lectual property; prescription; real and personal property.</p><p>property tax Levy imposed on real estate (land and buildings) and in  some jurisdictions on personal property such as automobiles, jewelry, and</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1554 I prophet &#x25BA; proscenium</p><p>furniture. Some countries also levy property taxes on farm equipment,  business equipment, and inventories as well as intangibles such as stocks  and bonds. Property taxes are usually levied by local or state governments  rather than national governments, and they are a major source of tax rev�  enue. Property taxes existed in the ancient world first as land taxes and  later as taxes on farmhouses, livestock, and so on. The administration of  a property tax involves identifying the property to be taxed, assessing its  value, determining the appropriate tax rate, and collecting the requisite  sum of money. Though sometimes burdensome to the poor, property taxes  generally tend to redistribute the benefits of wealth from higher to lower  income groups, since they often pay for schools and other services used  by low-income groups. See also capital-gains tax; consumption tax; income  tax; progressive tax; regressive tax.</p><p>prophet Person who speaks by divine inspiration, revealing or inter�  preting the will of a god. Prophets have appeared in many religions  throughout history. The most familiar in the West are such Old Testament  leaders as Moses, Isaiah, and Daniel, along with the Prophet Muhammad.  In contrast to the diviner or interpreter of omens (see divination), who may  answer private questions, prophets often address the destiny and moral  life of a whole people. Some prophets seek to create a new society that  will realize their message and thus found new religions. Others may look  only to reform or purify an existing society and religion. The tone of  prophecy ranges widely, from ecstasy, inspired utterance, and ethical fer�  vor to passionate social criticism, prediction of the future, and expecta�  tion Of APOCALYPSE.</p><p>Prophet, The orig. Tenskwatawa (b. c. March 1768, Old Chilli-  cothe, Ohio�d. 1834, Argentine, Kan., U.S.) North American Indian  leader. The brother of Tecumseh, he maintained a strong following among  the Shawnee on the strength of his 1805 declaration that he had received  a message from the �Master of Life� and had contact with the supernatu�  ral. Advocating a return to traditional ways of life, he rejected the white  man�s introduction of alcohol, textile clothing, and individual ownership  of property, and he worked with Tecumseh for an Indian confederacy to  resist U.S. encroachment on Indian land. In Tecumseh�s absence he  allowed the Shawnee to be drawn into and defeated at the Battle of Tippe�  canoe (1811).</p><p>Prophet's Mosque House of worship built on the site of Muhammad�s  house in Medina, considered one of the three holiest places of Islam. It was  originally a simple brick structure surrounding an enclosed courtyard  where people gathered to hear Muhammad. Muhammad later built roofed  galleries to shelter his visitors, and in 628 a pulpit was added to raise him  above the crowd. In 706 Caliph al-Walld I pulled down the original build�  ing and built a mosque on the site, which contains Muhammad�s tomb.  The mosque served as the model for later Islamic architecture.</p><p>proportion/proportionality In algebra, equality between two  _ RATIOS. In the expression alb = dd, a and b are in the same proportion as</p><p>c and d. A proportion is typically set up to solve a word problem in which  wm one of its four quantities is unknown. It is solved by multiplying one</p><p>M numerator by the opposite denominator and equating the product to that</p><p>of the other numerator and denominator. The term proportionality  describes any relationship that is always in the same ratio. The number  [jj| of apples in a crop, for example, is proportional to the number of trees in</p><p>the orchard, the ratio of proportionality being the average number of  apples per tree.</p><p>proportional representation Electoral system in which the share of  seats held by a political party in the legislature closely matches the share  of popular votes it received. It was devised in Europe in the mid-19th  century to guarantee minority groups more representation than was pos�  sible under the majority or plurality systems. Its supporters claim that it cre�  ates a more accurate reflection of public opinion; its opponents argue that  by allowing more parties in a legislature, it may result in weaker, less  stable governments. Two methods for apportioning seats are the single-  transferable-vote method, under which voters rank candidates by prefer�  ence, and the list system, under which voters select a party�s list of  candidates rather than individuals. Some countries (e.g., Germany and  Russia) use a combination of plurality and proportional methods for allo�  cating seats in the lower house of the national legislature. See also leg�  islative APPORTIONMENT.</p><p>propositional attitude Psychological state expressed by a verb that  may take a subordinate clause beginning with �that� as its complement.  Verbs such as �believe,� �hope,� �fear,� �desire,� �intend,� and �know�</p><p>all express propositional attitudes. The linguistic contexts created by their  use are typically referentially opaque (see intentionality) in the sense that  the substitution of co-referential expressions within them may change the  �truth value� (true or false) of the containing sentence. Thus, to use Ber�  trand Russell�s example, though it is true that Peter believes that Walter  Scott was a Scotsman, it may be false that he believes that the author of  Waverley (who is Scott) was a Scotsman.</p><p>propositional calculus Formal system of propositions and their logi�  cal relationships. As opposed to the predicate calculus, the propositional  calculus employs simple, unanalyzed propositions rather than predicates  as its atomic units. Simple (atomic) propositions are denoted by lower�  case Roman letters (e.g., p, q), and compound (molecular) propositions  are formed using the standard symbols a for �and,� v for �or,� z&gt; for �if  . . . then,� and �&#x25A0; for �not.� As a formal system, the propositional calcu�  lus is concerned with determining which formulas (compound proposi�  tion forms) are provable from the axioms. Valid inferences among  propositions are reflected by the provable formulas, because (for any for�  mulas A and B) Ad B is provable if and only if B is a logical conse�  quence of A. The propositional calculus is consistent in that there exists  no formula A in it such that both A and �&#x25A0; A are provable. It is also com�  plete in the sense that the addition of any unprovable formula as a new  axiom would introduce a contradiction. Further, there exists an effective  procedure for deciding whether a given formula is provable in the sys�  tem. See also logic, predicate calculus, laws of thought.</p><p>propositional function Sentencelike expression that may be thought  of as obtained from a sentence by substituting variables for constants  occurring in the sentence. For example, �x was a parent of y� may be  thought of as obtained from �Adam was a parent of Abel.� A proposi�  tional function therefore has no truth-value, becoming true or false only  when its free variables are replaced by constants of appropriate syntactic  categories (e.g., �Abraham was a parent of Isaac�).</p><p>proprietary colony Type of settlement in British North America  (1660-90). To repay political and financial debts, the British crown,  beginning with Charles II, awarded supporters vast tracts of land in colo�  nial New York, New Jersey, Pennsylvania, Maryland, and the Carolinas.  The proprietors were to supervise and develop the colonies, which became  successful enterprises. By 1690 concern about the colonies� growing inde�  pendence from control by British officials led to the end of proprietary  grants.</p><p>proprioception V.pro-pre-o-'sep-shonX Perception of stimuli relating to  position, posture, equilibrium, or internal condition. Receptors (nerve end�  ings) in skeletal muscles and on tendons provide constant information on  limb position and muscle action for coordination of limb movements.  Awareness of equilibrium changes usually involves perception of gravity.  In humans, gravity, position, and orientation are registered by tiny grains  called otoliths moving within two fluid-filled sacs in the inner ear in  response to any change in position or orientation. Their motion is detected  by sense hairs. Rotation is detected by the inertial lag of fluid in the semi�  circular canals acting on the sense hairs. The central nervous system inte�  grates signals from the canals to perceive rotation in three dimensions.  See also sense.</p><p>propylaeum N.pra-po-'le-om, .pro-po-'le-omV In ancient Greek archi�  tecture, a structure forming an entrance or gateway to a sacred enclosure,  usually consisting, at the least, of a porch supported by columns both out�  side and within the actual gate. The term is often used in the plural (pro-  pylaea). The most famous example is the great Propylaea designed by  Mnesicles for the Athenian Acropolis. The name propylaea was also  applied to various 18th-19th-century Neoclassical and Romantic monu�  mental gateways.</p><p>proscenium \pro-'se-ne-3m\ In a theatre, the frame or arch separating  the stage from the auditorium, through which the action of a play is viewed.  In ancient Greek theatres, the proskenion was an area in front of the SKENE  that eventually functioned as the stage. The first permanent proscenium  in the modern sense was built in 1618 at the Farnese Theatre in Parma.  Though the arch contained a stage curtain, its main purpose was to pro�  vide a sense of spectacle and illusion; scene changes were carried out in  view of the audience. Not until the 18th century was the curtain com�  monly used to hide scene changes. The proscenium opening was of par�  ticular importance to 19th-century realist playwrights, for whom it served  as a picture frame or an invisible wall through which the audience expe�  rienced the illusion of spying on the characters.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>prose &#x25BA; protectionism I 1555</p><p>prose Literary medium distinguished from poetry especially by its  greater irregularity and variety of rhythm and its closer correspondence  to the patterns of everyday speech. Though it is readily distinguishable  from poetry in that it does not treat a line as a formal unit, the significant  differences between prose and poetry are of tone, pace, and sometimes  subject matter.</p><p>prose poem Work in prose that has some of the technical or literary  qualities of poetry (such as regular rhythm, definitely patterned structure,  or emotional or imaginative heightening) but that is set on a page as prose.  The form took its name from Charles Baudelaire�s Little Poems in Prose  (1869). Other writers of prose poems include, in the 19th century, Stephane  Mallarme, Arthur Rimbaud, Friedrich Holderlin, Novalis, and Rainer Maria  Rilke, and in the 20th, Amy Lowell (in her �polyphonic prose�) and such  contemporary poets as John Ashbery.</p><p>prosecutor Government attorney who presents the state�s case against  the defendant in a criminal prosecution. In some countries (France, Japan),  public prosecution is carried out by a single office. In the U.S., states and  counties have their own prosecutors. Only at the federal level is the sys�  tem unitary; the U.S. attorney general�s office appoints a U.S. attorney for  each federal district. In most state and local jurisdictions, prosecutors are  elected to office. Whether elected or appointed, prosecutors are often sub�  ject to political pressures. A prosecutor takes charge of the investigation  once a crime has been committed, presents evidence at a hearing before  a grand jury, and questions witnesses during the trial. See also independent  counsel.</p><p>Proserpina See Persephone</p><p>prosody Vpra-so-de, 'pra-z9-de\ Study of the elements of language,  especially metre, that contribute to rhythmic and acoustic effects in poetry.  The basis of �traditional� prosody in English is the classification of verse  according to the syllable stress of its lines. Effects such as rhyme scheme,  alliteration, and assonance further influence a poem�s �sound meaning.�  Nonmetrical prosodic study is sometimes applied to modern poetry, and  visual prosody is used when verse is �shaped� by its typographical  arrangement. Prosody also involves examining the subtleties of a poem�s  rhythm, its �flow,� the historical period to which it belongs, the poetic  genre, and the poet�s individual style.</p><p>Prosser, Gabriel See Gabriel</p><p>prostaglandin \,pras-t3-'glan-d3n\ Any of a class of organic com�  pounds that occur in many animal tissues and have diverse hormonelike  effects in animals (see hormone). Their common chemical structure is  derived from a fatty acid with 20 carbon atoms. They have important  effects on blood pressure, blood clotting, pain sensation, and reproduction  mechanisms, but one prostaglandin may have different and even opposite  effects in different tissues. They hold promise for treating heart disease and  viral diseases and may be useful in contraception. Some substances that  inhibit prostaglandin synthesis (see aspirin) are useful in controlling pain,  asthma attacks, or anaphylactic shock or as anticoagulants.</p><p>prostate cancer Malignant tumour of the prostate gland. Prostate can�  cer commonly occurs in men over age 50. Symptoms include frequent or  painful urination, blood in the urine, sexual dysfunction, swollen lymph  nodes in the groin, and pain in the pelvis, hips, back, or ribs. The like�  lihood of developing prostate cancer doubles if there is a family history.  Treatment may include surgery, radiation therapy, hormone therapy, che�  motherapy, or a combination of two or more of these approaches.</p><p>prostate gland Vpras-,tat\ Chestnut-shaped male reproductive organ,  located under the bladder, which adds secretions to the sperm during ejacu�  lation of semen. It surrounds the urethra (see urinary system) and is rounded  at the top, narrowing to a blunt point. The prostate consists of 30-50  glands, supported by connective tissue, that discharge fluids into the ure�  thra and two ejaculatory ducts. Those ducts, which also carry sperm and  fluid discharged by the seminal vesicles, join the urethra inside the pros�  tate. The prostate contributes 15-30% of the seminal fluid. It reaches its  mature size at puberty. Around age 50, it commonly shrinks and decreases  its secretions; an increase in size after midlife may be due to inflamma�  tion or malignancy. See also prostatic disorder.</p><p>prostatic disorder \pra-'sta-tik\ Abnormality or disease of the pros�  tate gland. About half of all men over 60 have some nonmalignant enlarge�  ment, or benign prostatic hyperplasia (BPH). The gland may eventually  compress the urethra, causing problems urinating. Severe cases can lead</p><p>to infection, bladder stones, obstruction, and kidney failure. Prostate can�  cer, also found mainly in older men, can be deadly but usually grows so  slowly that most patients die of something else before the cancer spreads.  Since surgery and radiation therapy often lead to incontinence and impo�  tence, many cases are monitored (through prostate-specific antigen, or  PSA, tests) and treated only if necessary. Gonorrhea and other bacterial  infections involving the prostate are treated with antibiotics.</p><p>prosthesis \pras-'the-s3s\ Artificial substitute for a missing part of the  body, usually an arm or leg. Prostheses have evolved from wooden legs  and hooks that replaced hands to sophisticated plastic, fibreglass, and  metal devices designed to fit limbs amputated at different points. They  may have working joints and allow motion either by amplification of  electric current generated by muscle contractions or by actual attachment  to the muscles. Arm prostheses usually allow some degree of grasping  and manipulation. External or implanted breast prostheses are used after  mastectomy.</p><p>prostitution Practice of engaging in sexual activity, usually with indi�  viduals other than a spouse or friend, in exchange for immediate payment  in money or other valuables. Prostitutes may be of either sex and may  engage in either heterosexual or homosexual activity, but historically most  prostitution has been by females with males as clients. Prostitution is a  very old and universal phenomenon; also universal is condemnation of  the prostitute but relative indifference toward the client. Prostitutes are  often set apart in some way. In ancient Rome they were required to wear  distinctive dress; under Hebrew law only foreign women could be pros�  titutes; in prewar Japan they were required to live in special sections of  the city. In medieval Europe prostitution was licensed and regulated by  law, but by the 16th century an epidemic of venereal disease and post-  Reformation morality led to the closure of brothels. International coop�  eration to end the traffic in women for the purpose of prostitution began  in 1899. In 1921 the League of Nations established the Committee on the  Traffic in Women and Children, and in 1949 the UN General Assembly  adopted a convention for the suppression of prostitution. In the U.S. pros�  titution was first curtailed by the Mann Act (1910), and by 1915 most  states had banned brothels (Nevada being a notable exception). Prostitu�  tion is nevertheless tolerated in most U.S. and European cities. In The  Netherlands many prostitutes have become members of a professional  service union, and in Scandinavia government regulations emphasize  hygienic aspects, requiring frequent medical examination and providing  free mandatory hospitalization for anyone found to be infected with vene�  real disease. Prostitutes are very often poor and lack skills to support  themselves; in many traditional societies there are few other available  money-earning occupations for women without family support. In devel�  oping African and Asian countries, prostitution has been largely respon�  sible for the spread of AIDS and the orphaning of hundreds of thousands  of children.</p><p>Protagoras \pro-'tag-o-r3s\ (b. 485, Abdera, Greece�d. c. 410 bc)  Greek philosopher, first and most famous of the sophists. He spent most  of his life at Athens, where he considerably influenced contemporary  thought on moral and political questions. Plato named one of his dialogues  after him. Protagoras claimed to teach men �virtue� in the conduct of their  daily lives. He is best known for his dictum, �Man is the measure of all  things� (see relativism; ethical relativism). Though he adopted conventional  moral ideas, his work Concerning the Gods advocated agnosticism regard�  ing religious belief. He was accused of impiety, his books were publicly  burned, and he was exiled from Athens c. 415 bc.</p><p>protectionism Policy of protecting domestic industries against foreign  competition by means of tariffs, subsidies, import quotas, or other handi�  caps placed on imports. The chief protectionist measures, government-  levied tariffs, raise the price of imported articles, making them less  attractive to consumers than cheaper domestic products. Import quotas,  which limit the quantities of goods that can be imported, are another pro�  tectionist device. Wars and economic depressions historically have  resulted in increases in protectionism, while peace and prosperity have  tended to encourage free trade. Protectionist policies were common in  Europe in the 17th�18th centuries under mercantilism. Britain abandoned  many of its protectionist laws in the 19th century, and by World War I  tariffs were low throughout the Western world. Economic and political  dislocation led to rising customs barriers in Europe in the 1920s, and the  Great Depression produced a spate of protectionist measures; world trade  shrank drastically as a result. The U.S. had a long history of protection�  ism, with tariffs reaching high points in the 1820s and the Great Depres-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1556 I protectorate &#x25BA; protoceratops</p><p>sion, but in 1947 it became one of 23 nations to sign the General Agreement  on Tariffs and Trade (GATT), which substantially reduced customs tariff's  while reducing or eliminating quotas. Despite trade agreements such as  GATT and NAFTA, calls for protectionism are still heard in many coun�  tries when industries suffer severely from foreign competition. See also  trade agreement; World Trade Organization.</p><p>protectorate Relationship in which one country exercises some deci�  sive control over another country or region. The degree of control may  vary from one in which the protecting state guarantees the safety of the  other to one that is a disguised form of annexation. Though the relation�  ship is an ancient one, the use of the term dates only from the 19th cen�  tury. In modern times most protectorates have been established by treaties  requiring the weaker state to surrender management of its international  relations, thus losing part of its sovereignty.</p><p>protein Any of numerous organic compounds, complex polymers of  amino acids that are involved in nearly every aspect of the physiology and  biochemistry of living organisms. Twenty different amino acids are com�  mon to proteins, linked in chains of hundreds to thousands of units. An  active protein molecule has three important levels of structure: primary  (the amino acid sequence), determined by the genes; secondary (the geo�  metric shape, often a helix), determined by the angles of the covalent  bonds between and within amino acids; and tertiary (the looped and folded  overall shape), determined largely by attraction between oppositely  charged groups (and repulsion between like charged groups) on amino-  acid side chains and especially by hydrogen bonding. The tertiary struc�  ture, which can be globular or sheetlike with ridges, crevices, or pockets,  often holds the key to a protein�s biological activity. Proteins can serve,  e.g., as structural material (as in connective tissue and hair; see collagen;  keratin), as enzymes and hormones, as transporters of essential substances  such as oxygen (see hemoglobin), as antibodies, or as regulators of gene  expression. Some proteins are simple (amino acids only), some conju�  gated (see conjugation) to other groups, often vitamins or metal atoms  needed in tiny amounts in the diet (see coenzyme; cofactor). Rhodopsin  and hemoglobin are conjugated proteins. Proteins may be covalently  linked to other atoms or molecules, as to sugars (glycoproteins), phosphate  groups (phosphoproteins), or sulfur (sulfoproteins). Proteins are an essen�  tial human nutrient, obtained from both plant and animal foods. Their  greatest commercial use is in food products; they are also employed in  adhesives, plastics, and fibres.</p><p>proteolysis X.pro-te-'a-lo-sosX Process in which a protein is broken down  partially, into peptides, or completely, into amino acids, by proteolytic  enzymes, present in bacteria and in plants but most abundant in animals.  Proteins in food are attacked in the stomach by pepsin and in the small  intestine mainly by trypsin and chymotrypsin from the pancreas. Pro�  teolytic enzymes are secreted as zymogens, which are themselves con�  verted by proteolysis to their active forms. Many other zymogens or  precursors undergo proteolysis to form active enzymes or proteins (e.g.,  fibrinogen to fibrin). In cells, proteolytic degradation of old proteins is  part of cellular maintenance.</p><p>Proterozoic V.pra-to-ro-'zo-ik, .pro-ts-ro-'zo-ikN Eon Younger of the  two divisions of Precambrian time, from 2.5 billion to 543 million years  ago. Proterozoic rocks have been identified on all the continents and often  constitute important sources of metallic ores, notably of iron, gold, cop�  per, uranium, and nickel. The many small protocontinents that had formed  during early Precambrian time had coalesced into one or several large  landmasses by the beginning of the Proterozoic. Rocks of the Proterozoic  contain many traces of primitive life forms, such as the fossil remains of  bacteria and blue-green algae (see cyanobacteria).</p><p>Protestant ethic Value attached to hard work, thrift, and self-discipline  under certain Protestant doctrines, particularly those of Calvinism. Max  Weber, in The Protestant Ethic and the Spirit of Capitalism (1904-05),  held that the Protestant ethic was an important factor in the economic  success of Protestant groups in the early stages of European capitalism, in  that worldly success came to be interpreted as a sign of the individual�s  election to eternal salvation. Weber�s thesis was variously criticized and  expanded throughout the 20th century. See also Protestantism; Richard H.  Tawney.</p><p>Protestantism One of the three major branches of Christianity, origi�  nating in the 16th-century Reformation. The term applies to the beliefs of  Christians who do not adhere to Roman Catholicism or Eastern Orthodoxy.  A variety of Protestant denominations grew out of the Reformation. The</p><p>followers of Martin Luther established the evangelical churches of Ger�  many and Scandinavia; John Calvin and more radical reformers such as  Huldrych Zwingli founded Reformed churches in Switzerland, and Calvin�s  disciple John Knox established a church in Scotland (Presbyterianism).  Another important branch of Protestantism, represented by the Church of  England and Episcopal Church, had its origins in 16th-century England and  is now the Protestant denomination closest to Roman Catholicism in the�  ology and worship. The doctrines of the various Protestant denominations  vary considerably, but all emphasize the supremacy of the Bible in mat�  ters of faith and order, justification by grace through faith and not through  works, and the priesthood of all believers. In the early 21st century there  were nearly 350 million Protestants in the world. See also Adventist, Bap�  tist, Society of Friends, Mennonite, Methodism.</p><p>Proteus \'pro-te-3s\ In Greek mythology, the prophetic old man of the  sea and the shepherd of sea animals such as seals. He was subject to  Poseidon. He knew all things�past, present, and future�but disliked  telling what he knew. Those who wanted information from him had to  catch him sleeping and bind him. He would try to escape by changing his  form, but if a captor held him fast he gave the wished-for answer and  plunged into the sea.</p><p>prothrombin \pro-'thram-bin\ Carbohydrate-protein compound in  plasma essential to coagulation. In response to bleeding, a complex series  of clotting-factor interactions leads to its conversion by thromboplastin to  thrombin, which transforms fibrinogen in plasma into fibrin. Fibrin and  platelets combine to form a clot. Hemophilia is caused by a hereditary lack  of one of the clotting factors. Vitamin K is needed to synthesize prothrom�  bin, so conditions that impair the vitamin�s absorption result in prothrom�  bin deficiency and a tendency to prolonged bleeding.</p><p>protist \'pro-t9St\ Any member of a kingdom (Protista) of diverse eukary�  otes, including algae, protozoans, and lower fungi (see fungus). Most are  single-celled organisms, though the algae tend to be multicellular. Many  can move, mainly by using flagella (see flagellum), cilia (see cilium), or  footlike extensions (pseudopodia). The kingdom was developed to accom�  modate intermediate organisms that, even though they possessed some  plant or animal characteristics, did not exhibit the specialized features  indicative of those groups. Some protists are considered the ancestors of  multicellular plants, animals, and fungi. The term was first suggested in  1866 by Ernst Haeckel. With the development of advanced biochemical,  genetic, and imaging techniques, previously established relationships  have come under scrutiny, and it is now thought that some groups are less  closely related to one another than once believed. As a result, the clas�  sification of protists, while convenient, is no longer entirely satisfactory.</p><p>Proto-Geometric style Visual art style of ancient Greece that sig�  naled the reawakening of technical  proficiency and conscious creative  spirit after the collapse of the  Minoan and Mycenaean civilizations,  around the 12th century bc. The  vocabulary of the style was limited  to circles, arcs, triangles, and wavy  lines, all derived from Minoan-  Mycenaean representations of  aquatic and plant life. On pottery,  these design elements were carefully  placed in horizontal bands, mainly at  a vase�s shoulder or belly. Its lower  portion was usually either left plain  or painted in a solid glossy black pig�  ment inherited from Bronze Age art�  ists.</p><p>protoceratops</p><p>N.pro-ts-'ser-o-.tapsN Any member of  a genus of quadrupedal dinosaurs  found as fossils in Gobi deposits of  the Cretaceous period (144-65 million years ago). The hind limbs were  more strongly developed than the forelimbs; the back was arched. Adults  were about 7 ft (2 m) long and probably weighed about 400 lbs (180 kg).  The skull was about one-fifth the body length. Bones in the skull grew  backward into a perforated frill. The jaws were beaklike and toothed.  There may have been a hornlike structure on top of the snout. Long spines  on the well-developed tail suggest that protoceratops was semiaquatic.</p><p>Proto-Geometric amphora from Ath�  ens, early 10th century bc; in the Ker-  ameikos Museum, Athens.</p><p>HIRMER FOTOARCHIV, MUNICH</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Protococcus &#x25BA; Proudhon I 1557</p><p>Protococcus \,pro-t3-'ka-k9s\ or Pleurococcus Genus of green algae.  Popularly called moss though not actually classified as such, it is found  as a thin, green covering on the moist, shaded side of trees, rocks, and  soil. The spherical cells, either solitary or clumped together forming short  false filaments, have heavy cell walls that protect them against excessive  water loss. Each cell contains a large dense chloroplast. The position of  Protococcus in classification systems is uncertain.</p><p>protocol In computer science, a set of rules or procedures for transmit�  ting data between electronic devices, such as computers. In order for  computers to exchange information, there must be a preexisting agree�  ment as to how the information will be structured and how each side will  send and receive it. Without a protocol, a transmitting computer, for  example, could be sending its data in 8-bit packets while the receiving  computer might expect the data in 16-bit packets. Protocols are estab�  lished by international or industrywide organizations. Perhaps the most  important computer protocol is OSI (Open Systems Interconnection), a  set of guidelines for implementing networking communications between  computers. The most important sets of Internet protocols are TCP/IP,  HTTP, and FTP.</p><p>proton Stable subatomic particle (one of the baryons) with a unit of posi�  tive electric charge and a mass 1,836 times that of the electron. Protons  are found in the atomic nucleus along with neutrons. For every nucleus  of a given element, the number of protons is always the same; this num�  ber is the element�s atomic number. A single proton is the nucleus of an  atom of ordinary hydrogen; as such, it is identical to the hydrogen ion  (H + ). Protons have antimatter counterparts (antiprotons), with the same  mass but a negative charge. Protons are used as projectiles in particle  accelerators to produce and study nuclear reactions. They are the chief  constituent of primary cosmic rays and are among the products of radio�  active decay (see radioactivity) and nuclear reactions.</p><p>protozoal X.pro-ts-'zo-slV diseases Diseases caused by protozoans.  These organisms may remain in the human host for their entire life cycle,  but many carry out part of their reproductive cycle in insects or other  hosts. For example, mosquitoes are vectors of Plasmodium, the cause of  malaria. See also entamoeba; Giardia lamblia; sleeping sickness.</p><p>protozoan N.pro-ts-'zo-siA Any of a group of small (usually micro�  scopic) single-celled protists. They are found in most soils, fresh water,  and oceans. While most are solitary individuals, various colonial forms  exist. The taxonomic relationships of protozoans to one another and to  other protists continue to be revised. The smallest known protozoans are  tiny blood parasites less than 2 microns long; the largest may be 16 mm  long and visible to the naked eye. Protozoan shapes vary, but all share  such eukaryotic features as lipid-protein membranes and membrane-  enclosed vacuoles and organelles (see eukaryote). They show wide varia�  tion in modes of movement, nutrition, and reproduction. Various  classification systems exist to group the protozoans. The major phyla  include Sarcomastigophora (flagellated forms and forms possessing cyto�  plasmic extensions called pseudopodia), Ciliophora (ciliated forms), and  Apicomplexa, Microspora, and Myxozoa (spore-producing forms). Api-  complexa and Microspora are sometimes included in the single phylum  Sporozoa. Commonly known protozoans include dinoflagellates, amoebas,  and paramecia (see Paramecium). See illustration opposite.</p><p>protractor Instrument for constructing and measuring plane angles. The  simplest protractor is a semicircular disk marked in degrees from 0� to  180�. A more complex protractor, for plotting position on navigation  charts, is called a three-arm protractor, or station pointer, and consists of  a circular scale connected to three arms. The centre arm is fixed, while  the outer two can be rotated to any desired angle relative to the centre  one. A related instrument is the course protractor, which allows naviga�  tors to measure the angular distance between north and the course plot�  ted on a navigation chart.</p><p>Proudhon \pru-'do n \, Pierre-Joseph (b. Jan. 15, 1809, Besangon,  France�d. Jan. 19, 1865, Paris) French journalist and socialist. After  working as a printer, he moved to Paris in 1838 and joined the socialist  movement. His What Is Property? (1840) created a sensation with such  phrases as �property is theft.� While working in Lyon (1843-48), he  encountered the Mutualists, a weavers� anarchist society whose name he  later adopted for his form of anarchism. His System of Economic Contra�  dictions (1846) was attacked by Karl Marx and initiated the split between  anarchists and Marxists. In Paris in 1848, Proudhon published radical  newspapers; imprisoned (1849-52), he was harassed by the police after</p><p>phylum Sarcomastigophora</p><p>subphylum Mastigophora</p><p>phylum</p><p>Ciliophora</p><p>cavity</p><p>undulating</p><p>membrane</p><p>-cilium</p><p>Tetrahymena</p><p>membranes</p><p>myoneme  (contractile  filament)</p><p>Vorticella</p><p>phylum</p><p>Apicomplexa</p><p>class Sporozoa</p><p>Representative protozoans.

The amoeba is one of the  most common sarcodines. Other members of the subphylum Sarcodina, such as the  radiolarians, heliozoans, and foraminiferans, usually possess protective coverings.  The heliozoan Pinaciophora is shown covered with scales. The subphylum Cilio�  phora, which includes the ciliated Tetrahymena and Vorticella, contains the greatest  number of protozoan species but is the most homogeneous group.

Aug. 22,1935, Norwich, Conn., U.S.)  U.S. writer. She studied at the University of Vermont. She began profes�  sional writing with commissioned nonfiction books on cooking, garden�  ing, and country living. She founded and edited (1984-86) Behind the  Times, a rural Vermont newspaper, and published stories in men�s out�  door magazines. Her first novel, Postcards (1992), depicting the decline  of the small farm, received the PEN/Faulkner Award. It was followed by  The Shipping News (1993, Pulitzer Prize, National Book Award) and  Accordion Crimes (1996). Her story collections Heart Songs (1988) and  Close Range (1999) also won high praise.</p><p>Proust Vpriist\, Marcel (b. July 10, 1871, Auteuil, near Paris,  France�d.

Bom to a wealthy  family, he studied law and literature.</p><p>His social connections allowed him  to become an observant habitue of  the most exclusive drawing rooms of  the nobility, and he wrote social  pieces for Parisian journals. He pub�  lished essays and stories, including  the story collection Pleasures and  Days (1896). He had suffered from  asthma since childhood, and c. 1897  he began to disengage from social  life as his health declined. Half-  Jewish himself, he became a major  supporter of Alfred Dreyfus in the  affair that made French anti-  Semitism into a national issue.</p><p>Deeply affected by his mother�s  death in 1905, he withdrew further  from society. An incident of invol�  untary revival of childhood memory  in 1909 led him to retire almost totally into an eccentric seclusion in his  cork-lined bedroom to write A la recherche du temps perdu (1913-27; In  Search of Lost Time, or Remembrance of Things Past). The vast seven-  part novel is at once a kind of autobiography, a vast social panorama of  France in the years just before and during World War I, and an immense  meditation on love and jealousy and on art and its relation to reality. One  of the supreme achievements in fiction of all time, it brought him world�  wide fame and affected the entire climate of the 20th-century novel.</p><p>Provencal language See Occitan language</p><p>Provence \pro-'va n s\ Historical, cultural, and governmental region,  southeast-coastal France. Provence was part of Roman Gallia Transalpina.  m With the breakdown of the Roman Empire in the late 5th century,</p><p>Provence was invaded successively by the Visigoths, Burgundians, and  Ostrogoths. It came under the rule of the Franks c. 536. During the 13th  century it was involved in the Albigensian Crusade. It was united with the  French crown in 1481. The language of Provence, Provencal, was impor�  tant in medieval literature, and Provence�s Romanesque architecture was  an outstanding cultural achievement of the Middle Ages. The region suf�  fered in the 16th-century Wars of Religion. In 1790, during the French  Revolution, it lost its political institutions and was divided into several  departements. The historical region of Provence is roughly coextensive  with the present-day region of Provence-Alpes-Cote d�Azur (pop., 2003  est.: 4,665,051), which has an area of 12,124 sq mi (31,400 sq km); its  capital is Marseille.</p><p>proverb Succinct and pithy saying that is in general use and expresses  commonly held ideas and beliefs. Proverbs are part of every spoken lan�  guage and folk literature, originating in oral tradition. Often a proverb is  found with variations in many different parts of the world. Literate soci�  eties dating to the ancient Egyptians have collected proverbs. One of the  earliest English proverb collections, The Proverbs of Alfred, dates from  c. 1150-80. In North America the best-known collection is probably Poor  Richard�s, an almanac published 1732-57 by Benjamin Franklin.</p><p>Providence City (pop., 2000: 173,618), capital of Rhode Island, U.S.  It is located at the head of Narragansett Bay on the Providence River.  Founded in 1636 by Roger Williams as a refuge for religious dissenters, it</p><p>was partly destroyed in King Philip's War in 1676. It played an important  role in the American Revolution and was a major port in trade with the  West Indies in the 18th century. Incorporated as a city in 1831, it became  the sole capital of the state in 1900. Previously it had shared that honour  with Newport since 1854. A seaport and an industrial and commercial  centre, it is the focus of a metropolitan area that includes Pawtucket and  East Providence. Educational institutions include Brown University and the  Rhode Island School of Design.</p><p>Provincetown Town (pop., 2000: 3,431), eastern Massachusetts, U.S.  At the northern tip of Cape Cod, Provincetown was the first landing place  of the Pilgrims in 1620, and the Mayflower Compact was drawn up in its  harbour. Incorporated as a town in 1727, it was a whaling and fishing port  in the 19th century. Bounded by the Cape Cod National Seashore, it is a  popular summer resort and noted artists� colony. The Provincetown Play�  ers theatre group originated there.</p><p>Provincetown Players U.S. theatrical company. It was founded in  1915 by a group of writers and artists in Provincetown, Mass., to encour�  age new and experimental works. Among their first productions, which  were often staged in members� homes, was the first play by Eugene  O'Neill, a founding member whose career was launched by the Players.  In 1916 the players moved to New York�s Greenwich Village. There they  introduced several more of O�Neill�s plays as well as works by Edna St.  Vincent Millay, Susan Glaspell, Paul Green, and dozens of other play�  wrights. The company disbanded after the stock-market crash of 1929,  though the Provincetown Playhouse has continued to serve intermittently  as a theatre into the 21st century.</p><p>Provisions of Oxford See Provisions of Oxford</p><p>Provisors, Statute of (1351) Law passed by the English Parliament  during the reign of Edward III.

Construction of railroads in the  1870s spurred the city�s development as a centre for the mining of silver,  lead, copper, and gold. The founding in 1875 of Brigham Young Acad�  emy (now Brigham Young University) also contributed to Provo�s growth.  The city�s industries include steel, canning, electronics, and textiles.

He made drawings for engravers before he came to the atten�  tion of Napoleon. His portrait of the empress Josephine (1805) exhibits the  seductive and mysterious quality with which he invested his portraits of  women.

He attacked popular amusements, especially plays, in his book  Histrio Mastix: The Players Scourge (1633). Archbishop William Laud had  him imprisoned; after he wrote more pamphlets attacking Laud and other  Anglicans, his ears were cut off. Released in 1640, Prynne brought about  Laud�s conviction and execution (1645). Elected to Parliament in 1648,  he was expelled for attacks on radical Puritans and later imprisoned for  refusing to pay taxes (1650-53).

The mane is short  and erect with no forelock. It was  discovered in western Mongolia in  the 1870s. The horse disappeared in  the wild in the 1960s, but the descen�  dants of specimens that had earlier  been taken to European zoos began  to be reintroduced into the Mongo�  lian steppe in the 1990s.</p><p>psalm Vsam\ Sacred song or poem. The term is most widely known from  the book of Psalms in the Bible. Its 150 psalms, ranging in subject from  songs of joyous faith and thanksgiving to songs of bitter protest and lam�  entation, rank among the immortal poems of all time. They have had a  profound influence on the liturgies of Judaism and Christianity. Their dat�  ing and authorship are highly problematic, and the tradition of assigning  them to King David is no longer accepted. In the original Hebrew text the  book had no name. When the Hebrew Bible was translated into Greek  (the Septuagint), it was titled Psalterion, referring to a stringed instrument  that would accompany such songs.</p><p>Pseudo-Demetrius See False Dmitry</p><p>Pseudo-Dionysius the Areopagite (fl. c. 500) Probably a Syrian  monk. Under the pseudonym Dionysius the Areopagite, he wrote a series  of treatises that united Neoplatonic philosophy (see Neoplatonism), Chris�  tian theology, and mystical experience. Their doctrinal content covers the  Trinity, the angelic world, and the Incarnation and redemption and pro�  vides an explanation of all that is. His treatise �On Divine Names� dis�  cusses the nature and effects of contemplative prayer. The Dionysian  corpus was absorbed into Greek and Eastern Christian theologies and also  influenced mystics in the Western church.

Such  manganese oxide mixtures may form large deposits and may occur in lake  or swamp bedded deposits and clays; it has been found in Germany,  France, Belgium, Scotland, Sweden, India, and the U.S. The name psi�  lomelane (from the Greek words for �smooth� and �black�) refers to its  typical black, smooth-surfaced, grape-bunch-shaped or stalactitic masses.</p><p>psoriasis Vso-'ri-o-sosX Chronic, recurrent skin disorder with reddish,  slightly elevated patches or bumps covered with silvery-white scales.  Spots may coalesce into large patches around a normal area. If the nails  are involved, they may become pitted, thick, and separated from the nail  bed. Skin injury, infection, stress, and certain drugs may trigger psoria�  sis. Skin cells move at an accelerated rate from the dermis into the epi�  dermis, where they slough off, causing inflammation. In some cases,  patients also have arthritis. Psoriasis often becomes less severe in the  summer and during pregnancy. There is no cure, but treatment with drugs  and ultraviolet light may help.</p><p>Psyche Vsl-ke\ In Greek and Roman mythology, a beautiful princess  who won Cupid�s love. Her beauty  was such that worshipers began to  turn away from Venus, and the envi�  ous goddess commanded her son  Cupid to make Psyche fall in love  with the most despicable of men. But  Cupid himself fell in love with  Psyche and hid her in a remote place,  where he visited her secretly under  cover of darkness. One night she lit  a lamp and discovered her lover�s  identity. He left angrily, and Psyche  wandered the earth searching for him  and was captured by Venus. After  Cupid rescued Psyche, Jupiter made  her immortal and gave her in mar�  riage to Cupid.</p><p>psychiatry Branch of medicine  concerned with mental disorders.</p><p>Until the 18th century, mental health  problems were considered forms of  demonic possession; gradually they  came to be seen as illnesses requir�  ing treatment. In the 19th century,  research into and classification and  treatment of mental illnesses advanced. Sigmund Freud�s psychoanalytic  theory dominated the field for many years before it was challenged by  behavioral and cognitive therapy and humanistic psychology in the mid-  20th century. Psychiatrists hold medical degrees and can prescribe drugs  and other medical treatments in addition to conducting psychotherapy.  The psychiatrist often works as a member of a mental health team that  includes clinical psychologists and social workers.</p><p>psychoanalysis Method of treating mental disorders that emphasizes  the probing of unconscious mental processes. It is based on the psycho�  analytic theory devised by Sigmund Freud in Vienna in the late 19th and  early 20th century. It calls for patients to engage in free association of  ideas, speaking to therapists about anything that comes to mind. Dreams  and slips of the tongue are examined as a key to the workings of the  unconscious mind, and the �work� of therapy is to uncover the tensions  existing between the instinctual drive of the id, the perceptions and actions</p><p>Psyche, depicted with wings, classical  sculpture; in the Louvre, Paris</p><p>AUNARI-ART RESOURCE/EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1560 I psycholinguistics &#x25BA; Ptah</p><p>of the ego, and the censorship imposed by the morality of the superego.  Careful attention is paid to early childhood experiences (especially those  with a sexual dimension), the memory of which may have been repressed  because of guilt or trauma; recalling and analyzing these experiences is  thought to help free patients from the anxiety and neuroses caused by  repression as well as from more serious illnesses known as psychoses (see  neurosis, psychosis). Some of Freud�s early associates, notably Carl Gustav  Jung and Alfred Adler, rejected his theories on many points and devised  alternative methods of analysis. Other important figures in psychoanaly�  sis, including Erik Erikson, Karen Horney, and Erich Fromm, accepted the  basic Freudian framework but contributed their own additions or modi�  fications.</p><p>psycholinguistics Study of the mental processes involved in the com�  prehension, production, and acquisition of language. Much psycholin�  guists work has been devoted to the learning of language by children and  on speech processing and comprehension by both children and adults.  Traditional areas of research include language production, language com�  prehension, language acquisition, language disorders, language and  thought, and neurocognition. See also linguistics.</p><p>psychological development Development of cognitive, emotional,  intellectual, and social capabilities and functioning over the course of  one�s life. It is the subject matter of the discipline of developmental psy�  chology. In infancy, language is acquired, perception, emotion, and memory  take shape, and learning and motor skills develop. In childhood, speech  emerges, cognitive abilities advance from concrete to abstract operations,  emotional responses become more sophisticated, and empathy and moral  reasoning begin to be employed. Adolescence is a time of rapid emotional  and intellectual growth, while adulthood is characterized by the maturing  of all developmental processes.</p><p>psychological testing Use of tests to measure skill, knowledge, intel�  ligence, capacities, or aptitudes and to make predictions about perfor�  mance. Best known is the IQ test; other tests include achievement tests�  designed to evaluate a student�s grade or performance level�and  personality tests. The latter include both inventory-type (question-and-  response) tests and projective tests such as the Rorschach (inkblot) and  thematic apperception (picture-theme) tests, which are used by clinical  psychologists and psychiatrists to help diagnose mental disorders and by  psychotherapists and counselors to help assess their clients. Experimen�  tal psychologists routinely devise tests to obtain data on perception, learn�  ing, and motivation. Clinical neuropsychologists often use tests to assess  cognitive functioning of people with brain injuries. See also experimental  psychology; psychometrics.</p><p>psychological warfare Use of propaganda against an enemy, sup�  ported by whatever military, economic, or political measures are required,  and usually intended to demoralize an enemy or to win it over to a dif�  ferent point of view. It has been carried on since ancient times. The con�  quests of Genghis Khan were aided by expertly planted rumours about  large numbers of ferocious Mongol horsemen in his army. Specialized  units were a major part of the German and Allied forces in World War II  and the U.S. armed forces in the Korean and Vietnam wars. Strategic psy�  chological warfare is mass communications directed to a very large audi�  ence or over a considerable expanse of territory; tactical psychological  warfare implies a direct connection with combat operations (e.g., the sur�  render demand). Consolidation psychological warfare consists of mes�  sages distributed to the rear of one�s own advancing forces for the sake  of protecting the line of communications, establishing military govern�  ment, and carrying out administrative tasks within such a government.</p><p>psychology Scientific discipline that studies mental processes and  behaviour in humans and other animals. Literally meaning �the study of  the mind,� psychology focuses on both individual and group behaviour.  Clinical psychology is concerned with the diagnosis and treatment of men�  tal disorders. Other specialized fields of psychology include child psychol�  ogy, educational psychology, sports psychology, social psychology, and  comparative psychology. The issues studied by psychologists cover a wide  spectrum, including learning, cognition, intelligence, motivation, emotion,  perception, personality, and the extent to which individual differences are  shaped by genetics or environment. The methods used in psychological  research include observation, interviews, psychological testing, laboratory  experimentation, and statistical analysis.</p><p>psychometrics Science of psychological measurement. Psychometri�  cians design and administer psychological tests (see psychological testing).</p><p>both to generate empirical data on mental processes and to refine their  understanding of measurement techniques and the statistical analysis of  results. Major concerns include test reliability and validity and the norm-  ing or standardization of results.</p><p>psychoneurosis See neurosis  psychopathology See abnormal psychology</p><p>psychopharmacology Study of the effect of drugs on the mind and  behaviour, particularly in the context of developing treatments for men�  tal disorders. Major psychopharmacological advances in the 20th century  include the development of tranquilizers, antidepressants, lithium carbon�  ate (for bipolar disorder), certain stimulants (including amphetamines), and  antipsychotic agents such as chlorpromazine (Thorazine), fluphenazine  (Prolixin), and haloperidol (Haldol).</p><p>psychophysics Branch of psychology concerned with the effect of  physical stimuli (such as sound waves) on mental processes. Psychophys�  ics was established by Gustav Theodor Fechner in the mid-19th century,  and since then its central inquiry has remained the quantitative relation  between stimulus and sensation. A key tenet has been Weber's law. Psy�  chophysical methods are used today in vision research and audiology, psy�  chological testing, and commercial product comparisons (e.g., tobacco,  perfume, and liquor).</p><p>psychosis \sI-'ko-s9s\ Serious mental derangement characterized by  defective or lost contact with reality. The primary psychoses are schizo�  phrenia and the delusional disorders (e.g., megalomania), but extreme  cases of depression and bipolar disorder, substance-induced delirium, and  certain varieties of dementia are also understood to share important fea�  tures with the psychoses. The major symptoms, aside from delusions and  hallucinations, are disorganized speech and behaviour and, often, mood  disturbances. Treatment usually consists of medication and counseling in  an institutional setting. Compare neurosis.</p><p>psychosomatic disorder Bodily ailment or symptom, caused by  mental or emotional disturbance, in which psychological stresses  adversely affect physiological (somatic) functioning to the point of dis�  tress. Psychosomatic disorders may include hypertension, respiratory ail�  ments, gastrointestinal disturbances, migraine and tension headaches,  sexual dysfunctions, and dermatitis. Many patients with psychosomatic con�  ditions respond to a combination of drug therapy and psychotherapy. See  also HYPOCHONDRIASIS.</p><p>psychosurgery Treatment of psychosis or other mental disorders by  means of brain surgery. The first such technique was the prefrontal  lobotomy. Fairly common from the 1930s through the 1950s, lobotomy  reduced neurotic symptoms such as agitation and aggressiveness but also  left patients apathetic and with a limited range of emotions; it has since  been largely replaced by the use of tranquilizing and antipsychotic drugs  (see psychopharmacology). A form of psychosurgery developed more  recently involves the placement of tiny lesions in specific areas of the  brain and has little effect on intellectual function or quality of life; it has  been used to treat obsessive-compulsive disorder and occasionally cases of  severe psychosis.</p><p>psychotherapy Treatment of psychological, emotional, or behaviour  disorders through interpersonal communications between the patient and  a trained counselor or therapist. The goal of many modern individual and  group therapies is to establish a central relationship of trust in which the  client or patient can feel free to express personal thoughts and emotions  and thus gain insight into his condition and generally share in the heal�  ing power of words. Such therapies include psychoanalysis and its variants  (see Alfred Adler; Carl Gustav Jung), client-centred or nondirective psycho�  therapy, Gestalt therapy (see Gestalt psychology), play and art therapy, and  general counseling. In contrast, behaviour therapy focuses on modifying  behaviour by reinforcement techniques without concerning itself with  internal states.</p><p>Ptah \'pta\ In Egyptian religion, the creator god. The patron of craftsmen,  especially sculptors, Ptah was identified by the Greeks with Hephaestus,  the divine blacksmith. He was represented as a man in mummy form,  wearing a skullcap and a short, straight false beard. He was originally the  local deity of Memphis, capital of Egypt from the 1st dynasty onward; the  political importance of Memphis caused Ptah�s cult to spread across  Egypt. With Sekhmet and Nefertem, he was one of the Memphite Triad  of deities.

Ptarmigan plumage changes from white in win�  ter to gray or brown, with barring, in spring and summer. The toes are  covered with stiff feathers above and below. The common ptarmigan (L.  mutus ) occurs throughout the British Isles, Europe, and North America,  where it is called rock ptarmigan. Ptarmigans survive winter in the Arc�  tic and on mountaintops by browsing shrubs and scratching up lichens  and leaves; they burrow in snow to sleep. Males begin group displays in  early spring and then separate and display singly in adjoining territories.</p><p>Pteranodon Uo-'ra-no-.danX Genus of extinct flying reptiles, descen�  dants of the pterodactyl. Fossils are known from Late Cretaceous (99-65  million years ago) deposits of Europe, Asia, and North America. Ptera�  nodon had a wingspan of 23 ft (7 m) or more. The largest specimen had  a wingspan of 50 ft (15.5 m). The body was about the size of a modem  turkey. Pteranodon had a crest at the back of the skull and long, pelican�  like, toothless jaws. They probably made nests and spent much time glid�  ing over the ocean searching for fish. They probably depended on air  currents for liftoff rather than on flapping their wings.</p><p>pterodactyl \,ter-3-'dak-t 3 l\ Any member of the pterosaur suborder  Pterodactyloidea, known from Late Jurassic and Cretaceous fossils  (159-65 million years ago) in eastern Africa and Europe. Members of the  typical genus, Pterodactylus , ranged from the size of a sparrow to that of  an albatross. Pterodactyls had slender, delicate teeth that were angled for�  ward (possibly for use as straining devices), long metacarpal bones, and  a short tail. They were probably able gliders but not efficient as active  fliers, and they apparently lacked feathers. Unlike the archaeopteryx, the  pterodactyl was not an ancestor of the birds.</p><p>pterosaur Vter-o-.sorX Any of several extinct flying reptiles (order Pte-  rosauria) that flourished during the Jurassic and Cretaceous periods  (206-65 million years ago). Pterosaurs hung by their long, slender hind  limbs when at rest. They soared and glided on fragile, membranous wings  that were attached to the long fourth finger of each forelimb and extended  along the flank. The first three fingers were slender, clawed, clutching  structures. Pterosaurs had a long, slender beak and a large brain. Ram-  phorhynchus had strong, sharply pointed teeth, a long tail, and a wing-  spread of about 3 ft (1 m). It probably obtained food by diving for fish.

He worked prin�  cipally in Alexandria. It is often dif�  ficult to determine which findings in  his great astronomical book, the  Almagest, are Ptolemy�s and which  are Hipparchus�s. The Sun, Moon,  planets, and stars, he believed, were  attached to crystalline spheres, cen�  tred on Earth, which turned to create  the cycles of day and night, the lunar  month, and so on. In order to explain  retrograde motion of the planets, he  refined a complex geometric model  of cycles within cycles that was  highly successful at predicting the  planets� positions in the sky. The  Earth-centred Ptolemaic system  became dogmatically asserted in  Western Christendom until the Sun-  centred Copernican system replaced it.</p><p>His Geography contained an estimate of the size of Earth, a description  of its surface, and a list of places located by latitude and longitude.

A Macedonian general of Alexander the Great, he and the other  generals divided the empire after Alexander�s death, Ptolemy becoming  satrap of Egypt. Alexander�s successors were soon at war. Ptolemy was  defeated in 306 by Antigonus I Monophthalmus, though he and the others  rebuffed Antigonus�s attack on Egypt. He earned the name Soter (�Sav�  iour�) after defeating Antigonus on Rhodes (304), but Antigonus was not  finally crushed until 301 at the Battle of Ipsus. Ptolemy secured and  expanded his empire through alliances and marriages. He and his fellow  kings won a final war (288-286) against Demetrius of Macedonia, freeing  Athens from Macedonian occupation. He obtained control of the League  of Islanders (including most of the Aegean islands), which formed the  basis of Egypt�s maritime supremacy. As king he respected Egyptian cul�  ture, blended Greek and Egyptian peoples and religions, and founded the  Library and Museum of Alexandria. After his death the Egyptians raised  him to the level of a god. He was succeeded by his son, Ptolemy II Phila-  DELPHUS.</p><p>Ptolemy II Philadelphus (b. 308, Cos�d. 246 bc) King of Egypt  (285-246 bc), second king of the Ptolemaic dynasty. He reigned as coruler  (285-282) with his father, Ptolemy I Soter, then purged his family of rivals,  including his first wife, and married his sister, Arsinoe II. Wars with the  rulers of the Seleucid and Antigonid dynasties weakened his influence in  the Aegean and brought near-disaster to his allies Athens and Sparta. He  concluded these wars by diplomacy and marriage alliances and managed  to regain his influence in the Aegean. He devised a buffer zone of pos�  sessions to protect Egypt from attack, and he dealt with reverses through  diplomacy. A prudent and enlightened ruler, he promoted economic devel�  opment and made Alexandria into a centre for poets and scholars.</p><p>Ptolemy lll-XV (r. 246-30 bc) Macedonian kings of the Ptolemaic  dynasty in Egypt. Ptolemy III Euergetes (�Benefactor�) (fl. 246-221)  defeated the ruler of the Seleucid dynasty in the Third Syrian War (245-  241). Ptolemy IV Philopator (�Father-loving�) (r. 221-205) allowed  Egypt to decline under his debauched rule. Ptolemy IX Soter II ruled with  his mother (116-110, 109-107), until she expelled him and installed his  brother Ptolemy X Alexander (r. 107-88). Alexander�s unpopularity  resulted in his expulsion, and he died at sea in 88. Soter II assumed sole  rule (88-81), installing his brother�s widow, his own daughter, with him.  Ptolemy XI Alexander II (r. 80) was the last fully legitimate Ptolemaic  king of Egypt. On the orders of Sulla, whose hostage he had been, he took  Ptolemy IX Soter II�s widow as wife and attempted to rule with her. This  being unacceptable to the queen, Ptolemy murdered her and took sole  power, for which the people of Alexandria killed him; his rule lasted 19  days. Of the remaining Ptolemies, Ptolemy XIV Theos Philopator II  shared power (47-44) with his sister Cleopatra; it was probably she who  had him assassinated, to make way for her son by Julius Caesar. Ptolemy  XV Caesar, or Caesarion, shared power with his mother from 44; he was  killed by Octavian (later Augustus) after Cleopatra�s suicide in 30. His  death marked the Roman conquest of Egypt and the dynasty�s end.</p><p>puberty In human physiology, the period of first becoming capable of  reproducing sexually. Occurring at about age 12 in girls and age 14 in  boys, puberty is characterized by the maturing of the genital organs, devel�  opment of secondary sex characteristics, and, in girls, onset of menstrua�  tion.

In the U.S., public health is  studied and coordinated on a national level by the Centers for Disease  Control and Prevention; internationally, the World Health Organization  plays an equivalent role.</p><p>public house or pub Establishment that serves alcoholic beverages  for consumption on the premises, especially in Britain. Under English  common law, inns and taverns were declared public houses responsible  for the well-being of travelers. They were expected to receive all travel�  ers in reasonable condition who were willing to pay for food, drink, and  lodging. In Tudor England, certain innkeepers were obliged by royal act  to maintain stables; others served as unofficial postmasters. The early  public houses were identified by simple signs that featured creatures such  as lions, dolphins, or swans. In the 18th century, the word Arms was added  to many pub names to indicate that the establishment was under the pro�  tection of a noble family. Though British public houses were traditionally  owned and operated by independent licensed proprietors, by the early 20th  century many were owned or associated with brewery companies.</p><p>public relations (PR) Aspect of communications that involves pro�  moting a desirable image for a person or group seeking public attention.  It originated in the U.S. in the early 20th century with pioneers such as  Edward L. Bernays and Ivy Ledbetter Lee. Government agencies in Britain  and the U.S. soon began hiring publicists to engineer support for their  policies and programs, and the public-relations business boomed after  World War II. Clients may include individuals such as politicians, per�  formers, and authors, and groups such as business corporations, govern�  ment agencies, charities, and religious bodies. The audience addressed  may be as narrow as male alternative-music fans between the ages of 21  and 30 or as broad as the world at large. A publicist�s functions include  generating favourable publicity and knowing what kind of story is likely  to be printed or broadcast. The task is complicated by the variety of exist�  ing media: besides newspapers, magazines, radio, and television, there are  publications of professional associations, direct-mail lists, on-site promo�  tional events, and so on. It consists largely of optimizing good news and  forestalling bad news; if disaster strikes, the publicist must assess the  situation, organize the client�s response so as to minimize damage, and  marshal and present information to the media.</p><p>Public Safety, Committee of See Committee of Public Safety</p><p>public school or independent school In the United Kingdom, any  of a small group of tuition-charging secondary schools that specialize in  preparing students for university and for public service. The name public  school dates from the 18th century, when the schools began attracting stu�  dents from beyond their immediate environs and thus became �public� as  opposed to local. Such schools are thus in fact private schools indepen�  dent of the state system. Although many schools have become coeduca�  tional, only boys attend the historically important schools Winchester  (1394), Eton (1440-41), Westminster (1560), and Harrow (1571); well-  known girls� schools include Cheltenham (1853), Roedean (1885), and  Wycomb Abbey (1896).

In most countries such  enterprises are state-owned and state-operated; in the U.S. they are mainly  privately owned, but they operate under close regulation. Given the tech�  nology of production and distribution, they are considered natural  monopolies, since the capital costs for such enterprises are large and the  existence of competing or parallel systems would be inordinately expen�  sive and wasteful. Government regulation in the U.S., particularly at the  state level, aims to ensure safe operation, reasonable rates, and service on  equal terms to all customers. Some states have experimented with deregu�  lation of electricity and natural-gas operations to stimulate price reduc�  tions and improved service through competition, but the results have not  been universally promising.</p><p>Public Works Administration U.S. government agency (1933-39).  It was established as part of the New Deal to reduce unemployment</p><p>through the construction of highways and public buildings. Authorized by  the National Industrial Recovery Act (1933) and administered by Harold  Ickes, it spent about $4 billion to build schools, courthouses, city halls,  public-health facilities, and roads, bridges, dams, and subways.

Contemporary publishing includes the production of materials in digital  formats such as CD-ROMs, as well as materials created or adapted for  electronic distribution. Publishing has evolved from small, ancient, and  law- or religion-bound origins into a vast industry that disseminates every  kind of information imaginable. In the modern sense of a copying indus�  try supplying a lay readership, publishing began in Hellenistic Greece, in  Rome, and in China. After paper reached the West from China in the 11th  century, the central innovation in Western publishing was Johannes Guten�  berg�s invention of movable type. In the 19th and 20th centuries, techno�  logical advances, the rise of literacy and leisure, and ever-increasing  information needs contributed to an unprecedented expansion of publish�  ing. Contemporary challenges in publishing include attempts at censor�  ship, copyright laws and plagiarism, royalties for authors and  commissions for literary agents, competitive marketing techniques, pres�  sures from advertisers affecting editorial independence, acquisition of  independent publishing concerns by conglomerates, and the loss of read�  ers to other media such as television and the Internet.</p><p>Pucci Vpti-cheV Emilio, marquess di Barsento (b.

At the Milan Conservatory he studied with Amil-  care Ponchielli (1834-86). Puccini entered his first opera, Le villi (1883),  in a competition; though it lost, a group of his friends subsidized its pro�  duction, and its premiere took place with immense success. His second,  Edgar (1889), was a failure, but Manon Lescaut (1893) brought him  international recognition. His mature operas included La Boheme (1896),  To sea (1900), Madam Butterfly (1904), and The Girl of the Golden West  (1910). All four are tragic love stories; his use of the orchestra was refined,  and he established a dramatic structure that balanced action and conflict  with moments of repose, contemplation, and lyricism. They remained  exceedingly popular into the 21st century. He was the most popular opera  composer in the world at the time of his death; his unfinished Turandot  was completed by Franco Alfano (1875-1954).</p><p>Pucelle \ptB-'sel\, Jean (b. 1300?�d. 1355?)

Freestanding structures up to  five stories tall were built around a central court. Each floor is set back  from the floor under it; the whole structure resembles a zigzag pyramid,  with terraces formed by the rooftops of the level below. Though rooms  often have connecting doorways, movement between levels is by means  of ladders through holes in the ceilings. Ground-floor rooms, used for  storage, have no outside doors. Each pueblo has at least two kivas.

The resulting agreement allowed the U.S. to publicly disavow  the confession the crew had signed while privately admitting its truth; the  U.S. also acknowledged the ship�s intrusion into North Korean waters and  agreed not to undertake similar intelligence gathering activities in the  future. An inquiry into the crew�s confession and the conduct of the ship�s  commander produced no apparent disciplinary action.</p><p>Pueblo Indian Any of the historic descendants of the prehistoric Ana-  sazi peoples who have for centuries lived in settled pueblos in what is now  northeastern Arizona and northwestern New Mexico. The contemporary  pueblos are divided into eastern and western. The eastern group includes  settlements along the Rio Grande in New Mexico (most notably Taos  Pueblo), while the western group includes the Hopi villages of northeast�  ern Arizona and the Zuni, Acoma, and Laguna villages of northwestern  New Mexico. The original Pueblo culture was characterized by both agri�  culture and the hunting of deer and antelope. Today agriculture predomi�  nates. Modern Pueblo social life centres on the village.

Even  though they have added to their inventory of material goods, the basic  fabric of the Pueblo social system, community of organization and native  religion, with modifications only of detail, has survived.</p><p>Pueblo pottery One of the most highly developed of the Native  American arts. Pueblo pots, made only by women of the tribe, are con�  structed of long �sausages� of clay that are coiled upward and then  smoothed out. Designs include geometric, floral, and animal patterns. The  method was developed during the Classical Pueblo period (c. 1050-1300)  and is still being used today. See photograph above.</p><p>Puente Vpwen-ta\, Tito orig.

The inner surface of the uterus is most  often infected, but lacerations of any part of the genital tract can give bac�  teria (often Streptococcus pyogenes ) access to the bloodstream and lym�  phatic system to cause septicemia, cellulitis (cellular inflammation), and  pelvic or generalized peritonitis. Severity varies. Puerperal fever has  become very rare in developed countries but is still seen after abortions  performed in unhygienic surroundings.</p><p>Puerto Rico officially Commonwealth of Puerto Rico Self-  governing island commonwealth of the West Indies, in the northeastern  Caribbean Sea; it is associated with the U.S. Area: 3,515 sq mi (9,104 sq  km). Population (2005 est.): 3,912,000. Capital: San Juan. Most of the  population is of Spanish descent, with significant minorities of people of  African and mixed (African-European) descent. Languages: Spanish,  English (both official). Religion: Christianity (predominantly Roman  Catholic; also Protestant). Currency: U.S. dollar. The island of Puerto Rico  may be divided into three geographic regions: the mountainous interior,  the northern plateau, and the coastal plains. It has a developing free-  market economy, of which manufacturing, financial services, and trade  (mostly with the U.S.) are the main components. Tourism is also an impor�  tant source of income. Puerto Rico�s chief of state is the U.S. president,  and its head of government is the commonwealth governor. The island  was inhabited by Arawak Indians when it was settled by the Spanish in  the early 16th century. It remained largely undeveloped economically until  the late 18th century. After 1830 it gradually developed a plantation  economy based on the export crops of sugarcane, coffee, and tobacco.  The independence movement began in the late 19th century, and Spain  ceded the island to the U.S. in 1898 after the Spanish-American War. In  1917 Puerto Ricans were granted U.S. citizenship, and in 1952 the island  became a commonwealth with autonomy in internal affairs. Voters reaf�  firmed the island�s commonwealth status in plebiscites in 1967, 1993, and  (tacitly) 1998, but Puerto Rican statehood remained a political issue into  the 21st century.</p><p>Puerto Vallarta Vpwer-to-ba-'yar-ta\ City (pop., 2000: 151,432),  west-central Mexico.

Jan. 8, 1632,  Dorfchemnitz, near Thalheim, Saxony�d. Oct. 13, 1694, Berlin) German  jurist and historian. The son of a pastor, he left the study of theology for  jurisprudence, philosophy, and history. He taught at the Universities of  Heidelberg (1661-68) and Lund (1670-77). His Elements of Universal  Jurisprudence (1660) and Of the Law and Nature of Nations (1672),  which were influenced by Hugo Grotius and Thomas Hobbes, departed from  the traditional approach of the medieval theologians to natural law in  arguing that there is no such creature as a natural slave�that all men have  a right to equality and freedom.

Puffballs are named for the fact that puffs of spores are  released when the dry and powdery tissues of the mature spherical fruit�  ing body (basidiocarp) are disturbed. Many are edible before maturity.</p><p>puffer or blowfish Any of about 90 species (family Tetraodontidae)  of fishes that, when disturbed, inflate  themselves into a globular shape  with air or water. Most species occur  in warm and temperate seas world�  wide; some occur in brackish or  fresh water. Puffers have tough, usu�  ally prickly, skin; their fused teeth  form a beaklike structure, split in the  center of each jaw. The largest grow  to 3 ft (90 cm) long, but most are  considerably smaller. Though they  contain a lethal toxin, they are some�  times eaten, especially in Japan,  where puffers (called fugu) are prepared by a specially trained chef.</p><p>puffin or sea parrot Any of three species (family Alcidae) of diving  birds with a large, brightly coloured,  triangular beak. Puffins nest in large  colonies on seaside and island cliffs.</p><p>Both parents carry up to 10 fish  crosswise in the bill to the nest (a  deep burrow); they feed the single  chick for about six weeks. They then  leave, and the chick waits alone for  its flight feathers to grow, living on  stored fat, and then flies out to sea by  itself. The common, or Atlantic, puf�  fin (Fratercula arctica) is about 12  in. (30 cm) long. The Pacific species  are the homed puffin ( F. corniculata )  and the tufted puffin (Limda cir-  rhata).</p><p>pug Breed of toy dog that probably  originated in China. Dutch traders  brought it to England in the late 17th  century. Squarely built and muscular,  the pug has a short muzzle, tightly  curled tail, large head, prominent  eyes, and small, drooping ears. It  stands 10-11 in. (26-28 cm) and  weighs about 13-18 lbs (6-8 kg). Its  short, glossy coat can be black, sil�  ver, or apricot fawn; there is a black  mask on the face. Loyal and alert,  pugs are valued as companions.</p><p>Pugachov V.pii-go-'choA, Yeme�  lyan (Ivanovich) (b. c. 1742,</p><p>Zimoveyskaya-na-Donu, Russia�d.</p><p>Jan. 21, 1775, Moscow) Russian  Cossack leader. He fought in the  Russian army (1763-70), then wan�  dered among settlements of the dis�  sident Old Beuevers. Learning of  Cossack discontent after their unsuccessful rebellion in 1772, he claimed  to be Tsar Peter III and decreed the abolition of serfdom. Vowing to depose  Catherine II, he gathered a large following of Cossacks and peasants in the  Ural region. After initial victories against the Russian army, he was  defeated, captured, and executed.</p><p>Puget Vpuj-'zheX, Pierre (b. Oct. 16, 1620, at or near Marseille,  France�d.

Thereafter he</p><p>worked chiefly in France as a painter and sculptor. While his work is in  the tradition of Roman Baroque, such sculptures as Milo of Crotona (c.  1671-82), in which the athlete is attacked by a lion while his hand is  caught in a tree stump, show a strain and anguish that suggest the works  of Michelangelo.</p><p>Puget Vpyti-jotX Sound Arm of the Pacific Ocean indenting northwest�  ern Washington, U.S. It was explored by the British navigator George  Vancouver in 1792 and named by him for Peter Puget, a second lieuten�  ant in his expedition, who probed the main channel. It has many deep�  water harbours, including Seattle, Tacoma, Everett, and Port Townsend,  which are shipping ports for the rich farmlands along the river estuaries.  It provides a sheltered area for recreational boating and salmon fishing.</p><p>Puglia \'pii-lya\ or Apulia \a-'pu-lya\ Autonomous regione, southeast�  ern Italy. It is located between the Adriatic Sea, the Apennines, and the  Gulf of Taranto. It was ruled in the early Middle Ages by Goths, Lom�  bards, and Byzantines and achieved its greatest glory under the Hohen-  staufen emperors, especially the 13th-century Holy Roman emperor  Frederick II. In 1861 it became part of the Italian kingdom. The region is  predominantly agricultural. Wheat, barley, and oats are grown on the plain  and in the more fertile parts of the plateaus, while olives, grapes, almonds,  figs, and vegetables predominate farther south; tobacco is a specialty of  the Lecce Plain. The wines of Puglia are the strongest in Italy and are  used to fortify other, lighter varieties. There are chemical and petrochemi�  cal industries in Bari and iron and steel plants in Taranto. The capital of  Puglia (pop., 2001 prelim.: 3,983,487) is Bari; the region has an area of  7,470 sq mi (19,348 sq km).</p><p>Pugwash Conferences Series of international meetings of eminent  scientists to discuss problems of nuclear weapons and world security. The  first meeting was held in 1957 at the estate of Cyrus Eaton in Pugwash,  Nova Scotia. The Pugwash organization was established to convene sub�  sequent conferences to discuss arms control and disarmament; these were  held in the Soviet Union, Britain, India, and the U.S., among other coun�  tries. The organization and its president and founding member, Joseph  Rotblat (born 1908), received the 1995 Nobel Prize for Peace.</p><p>puja \'pii-ja\ In Hinduism, a form of ceremonial worship. It may range  from brief daily rites in the home to an elaborate temple ritual. A typical  puja offers the image of a deity the honours accorded to a royal guest.  The god is gently roused from sleep, ritually bathed and dressed, served  three meals during the day, and ceremonially put to bed. Rituals may also  include a sacrifice and oblation to the sacred fire. Some pujas are per�  formed by the worshiper alone; others require a ritually pure person. A  puja may be performed for a specific purpose or simply as an act of devo�  tion.</p><p>Pukaskwa \pu-'kas-kw3\ National Park National park, central  Ontario, Canada.

After the war he became a reporter and then propri�  etor at German-language newspapers in St. Louis and entered Missouri  politics. In 1878 he merged the St. Louis Dispatch (founded 1864) and  the Post (founded 1875) into the Post-Dispatch, which soon became the  city�s dominant evening newspaper. Shifting his interests to New York  City, he purchased the World (1883) and founded the Evening World  (1887). He helped establish the pattern of the modern newspaper by com�  bining exposes of political corruption and crusading investigative report�  ing with publicity stunts, self-advertising, and sensationalism.

Pulleys are used singly or in combination to  transmit energy and motion. In belt drives, pulleys are attached to shafts at  their axes, and power is transmitted between the shafts by means of end�  less belts running over the pulleys. One or more independently rotating  pulleys can be used to gain mechanical advantage, especially for lifting  weights. The shafts around which the pulleys turn may attach them to  frames or blocks, and a combination of pulleys, blocks, and rope is called  a block and tackle. The pulley is considered one of the five simple machines.</p><p>Pullman, George M(ortimer) (b. March 3, 1831, Brocton, N.Y.,</p><p>U. S.�d. Oct. 19, 1897, Chicago, Ill.) U.S. industrialist. He moved to  Chicago as a young man and worked as a cabinetmaker for his brother.  In 1858 he remodeled two day coaches for a local railroad company into  sleeping coaches; eventually he set up his own firm, and the first true  Pullman sleeping car appeared in 1865. Becoming wealthy from his  invention, in 1867 he founded the Pullman Palace Car Company; the next  year he created the first dining car. In 1880 he built the town of Pullman  (now incorporated into Chicago) for its workers; a much-discussed social  experiment, the town was also the scene of the famous Pullman Strike of</p><empty-line/><p>Pullman Strike (May 11-c. July 20, 1894) Massive railroad strike in  the U.S. After financial reversals caused the Pullman Palace Car Co. to  cut wages by 25%, local union members called a strike. The company�s  president, George Pullman, refused arbitration, and union president Eugene</p><p>V. Debs called for a nationwide boycott of Pullman cars. Sympathy strikes  followed in 27 states. Violence broke out in Chicago, Ill., but Gov. John  Peter Altgeld refused to intervene. The U.S. attorney general, Richard  Olney, obtained an injunction against the strikers for impeding the mail  service, and federal troops were called in. Debs�s conviction for conspir�  ing against interstate commerce established that the Sherman Antitrust Act  could be enforced against labour-unions.</p><p>pulmonary alveolus Vpul-mo-.ner-e-al-'ve-s-tasV Any of the 300  million or so small air spaces in the lungs where carbon dioxide leaves  the blood and oxygen enters it. Alveoli form clusters (alveolar sacs) con�  nected by alveolar ducts to the bronchioles. Their thin walls contain  numerous capillaries, supported by a mesh of elastic and collagenous  fibres; gas exchange between them occurs by diffusion. A film of fatty  substances (surfactant) over the walls reduces surface tension, keeping  the alveoli from collapsing and making it easier to expand the lungs.  Alveolar macrophages (see leukocyte; lymphoid tissue) act as mobile scav�  engers, engulfing foreign particles in the lungs.</p><p>pulmonary heart disease or cor pulmonale \,kor-pul-m3-  'nal-e\ Enlargement and eventual failure of the right ventricle of the heart  due to disorders of the lungs or their blood vessels or chest wall abnor�  malities. Chronic disease is most often caused by chronic bronchitis or  emphysema. Symptoms include chronic cough, trouble in breathing after  exertion, wheezing, weakness, leg edema, right upper abdominal pain, and  neck vein distension. Pressure in the pulmonary artery rises and the right  ventricle enlarges in response, leading, if uncorrected, to heart failure.  Treatment includes a respirator, low-sodium diet, diuretics, digitalis, and  antibiotics for respiratory infection. Acute disease due to pulmonary embo�  lism is often treated by removal of the blockage.</p><p>pulsar in full pulsating radio star Any of a class of cosmic objects  that appear to emit extremely regular pulses of radio waves. A few give  off short rhythmic bursts of visible light, X rays, and gamma radiation as  well. Thought to be rapidly spinning neutron stars, they were discovered  by Antony Hewish and Jocelyn Bell Burnell in 1967 with a specially  designed radio telescope. More than 550 have been detected since. All  behave similarly, but the intervals between pulses (and thus their rotation  periods) range from one-thousandth of a second to four seconds. Charged  particles from the surface enter the star�s magnetic field, which acceler�  ates them so that they give off radiation, released as intense beams from  the magnetic poles. These do not coincide with the pulsar�s own axis of  rotation, so as the star spins, the radiation beams swing around like light�  house beams and are seen as pulses. Pulsars have been shown to be slow�</p><p>ing down, typically by a millionth of a second per year. It has been  calculated that pulsars �switch off� after about 10 million years, when  their magnetic fields weaken enough.</p><p>A pulsar emits two beams of electromagnetic radiation along its magnetic axis. If  the magnetic axis is offset from the rotational axis, the beams will sweep out circu�  lar paths as the star rotates, instead of remaining in one position. An observer in  the path of such a beam will thus detect a periodic pulse of radiation as the beam  sweeps by.</p><p>� MERRIAM-WEBSTER INC.</p><p>pulse Pressure wave in the arteries from contraction of the heart. It can  be felt where arteries are near the skin�s surface; it is usually read at the  carotid artery in the neck or at the wrist. Its rate, strength, and rhythm and  the contour of the wave provide valuable information but must be viewed  in context (e.g., rapid pulse occurs with serious heart disease, simple fever,  or vigorous exercise). The average adult pulse rate is 70-80 beats per  minute; the rate decreases with age and is generally faster in women.</p><p>puma See cougar</p><p>pumice Vpo-mosV Very porous, frothlike volcanic glass that has long  been used as an abrasive in cleaning, polishing, and scouring compounds.  It is also used in precast masonry units, poured concrete, insulation and  acoustic tile, and plaster. Pumice is igneous rock that cooled so rapidly  there was no time for it to crystallize. When it solidified, the vapours dis�  solved in it were suddenly released, and the whole mass swelled up into  a froth that immediately consolidated. Any type of lava may become  pumiceous under favourable conditions.</p><p>pump Machine that uses energy to raise, transport, or compress fluids.  Pumps are classified by how they transfer energy to the fluid. The basic  methods are volume displacement, addition of kinetic energy, and use of  electromagnetic force. Pumps in which displacement is accomplished  mechanically are called positive displacement pumps. Kinetic pumps pass  kinetic energy to the fluid by means of a rapidly rotating impeller (blade).  To use electromagnetic force, the fluid being pumped must be a good  electrical conductor. Pumps used to transport or pressurize gases are called  compressors, blowers, or fans.</p><p>pumpkin Fruit of certain varieties of Cucurbita pepo or C. moschata,  of the gourd family. In the U.S., the thick-growing, small-fruited bush, or  nontrailing, varieties of C. pepo are called squash, and the long-season,  long-trailing, large-fruited varieties are called pumpkin. Pumpkins pro�  duce very long vines and large (9-18 lb [4-8 kgj), globe-shaped, orange  fruits. Giant and miniature varieties are available. The usually lightly fur�  rowed or ribbed rind is smooth, and the fruit stem is hard and woody.

Pumpkins are used in the  U.S. for Halloween decorations.</p><p>Punch Hooknosed, humpbacked character in marionette and puppet  shows (see puppetry). Adapted from a stock character of the commedia  dell'arte, the puppet character was taken to France and England by Ital�  ian puppeteers in the 1660s. By 1700 every English puppet show featured  Punch (from Punchinello) and his wife, Judy. As marionettes became less  popular in the 1790s, smaller glove puppets were used in the popular  Punch-and-Judy play. The hooked nose and the brutal, vindictive, and  deceitful behaviour of the English Punch were established characteristics  by the 19th century. In France his popularity declined during the 19th and  20th centuries, and he disappeared there as a comic figure. Puppeteers in  England have carried on the tradition of Punch-and-Judy shows.</p><p>Punch English illustrated periodical published 1841-1992 and revived  in 1996 with a revised format. Initially a weekly radical paper, it became  famous for its satiric humour, caricatures, and cartoons. Among its famous  early staff members were William Thackeray and John Tenniel. A cover  drawing by Richard Doyle was used continuously from 1849 to 1956,  when each issue�s cover was made different, though the traditional fig�  ures of Punch and his dog Toby usually appeared somewhere.</p><p>punch press Machine tool that changes the size or shape of a piece of  material, usually sheet metal, by applying pressure to a die in which the  workpiece is held. The form and construction of the die determine the  shape produced on the workpiece. A punch press has two components:  the punch, which is attached to the reciprocating (back and forth, or up  and down) ram (plunger) of the machine; and the die, which is clamped  onto a bed or anvil whose flat surface is perpendicular to the path of the  ram. The punch pushes against the workpiece, which is held in the die.  Punch presses are usually driven by electric motors. See also hydraulic  PRESS.</p><p>punctuation Standard set of marks used in written and printed texts to  clarify meaning and to separate sentences, words, and parts of words. It  often marks discourse features such as intonational contours and pauses.  It may also convey information about a word (e.g., hyphens in compound  words) unrelated to speech patterns. In English, the period (.) marks the  end of a sentence or an abbreviation. The comma (,) usually separates  clauses, phrases, or items in a series. The colon (:) often introduces an  explanation or series of examples. The semicolon (;) usually separates  independent clauses. The em-dash (�) marks an abrupt transition. The  exclamation point (!) signals surprise. The question mark (?) signals a  question. The apostrophe (�) marks the possessive case or the omission  of letters. Quotation marks (� �) set off either quoted words or words used  _ with special significance.

It first gained importance as the capital of the Bhonsle Mar-  athas in the 17th century. Temporarily captured by the Mughals, it again  became the Maratha capital from 1714 until 1817, when it fell to the Brit�  ish. It served as the seasonal capital of the Bombay presidency, and its  mild weather has made it a popular tourist resort. It is a major educational  centre and headquarters of the Indian army�s southern command; it is  ringed by a sprawling complex of industrial suburbs.</p><p>Punic Wars Vpyii-nik\ or Carthaginian Wars Three wars (264-  241 bc, 218-201, 149-146) between Rome and Carthage. The first con�  cerned control of Sicily and of the sea lanes in the western Mediterranean;  it ended with Rome victorious but with great loss of ships and men on  both sides. In 218 Hannibal attacked Roman territory, starting from Spain  and marching overland into Italy with troops and elephants. After an ini�  tial Carthaginian victory, Fabius Maximus Cunctator harassed him wher�  ever he went without offering battle. Abandoning this tactic resulted in a  major Roman loss at the Battle of Cannae (216); that defeat drew the  Romans together and, though worn down, they managed to rally, even�  tually defeating Hannibal and driving him out of Italy (203). The Third  Punic War was essentially the siege of Carthage; it led to the destruction</p><p>of Carthage, the enslavement of its people, and Roman hegemony in the  western Mediterranean. The Carthaginian territory became the Roman  province of Africa.</p><p>Punjab \,p9n-'jab\ State (pop., 2001 prelim.: 24,289,296), northwestern  India. Bordered by Pakistan and the states of Jammu and Kashmir, Himachal  Pradesh, Haryana, and Rajasthan, it occupies an area of 19,445 sq mi  (50,362 sq km). The city of Chandigarh is the joint administrative capital  of Punjab and Haryana. In the 18th century the Sikhs (see Sikhism) built a  powerful kingdom in the Punjab, which came under British rule in 1849.  In 1947 the area was split between the new nations of India and Pakistan,  the smaller eastern portion going to India. It is the only Indian state with  a majority of Sikhs. Hindus make up about one-third of the population,  and there are smaller minorities of Christians, Jains, and Muslims. The  economy is based on agriculture and small- and medium-scale industry.</p><p>Punjabi \,p9n-ja-be\ language or Panjabi language Indo-Aryan  language of the Punjab in India and Pakistan. Punjabi has about 26 mil�  lion speakers in India and more than 60 million in Pakistan�nearly half  the population of the latter�but linguists have sometimes considered the  dialects of southwestern, western, and northern Punjab province in Paki�  stan a different language. Inhabitants of southern Punjab province have  agitated for consideration of their speech, Siraiki (with more than 12 mil�  lion speakers), as a distinct language, though Siraiki and Punjabi are  mutually intelligible.</p><p>punk Aggressive form of rock music that coalesced into an international  (though predominantly Anglo-American) movement in 1975-80. Origi�  nating in the countercultural rock of artists such as the Velvet Under�  ground and Iggy (Pop) and the Stooges, punk rock evolved in New York  City in the mid-1970s with artists such as Patti Smith and the Ramones.  It soon took root in London�where distinctly �punk� fashions, includ�  ing spiked hair and ripped clothing, were popularized�with bands such  as the Sex Pistols and the Clash, and later in California, with X, Black  Flag, and the Dead Kennedys. It is often marked by a fast, aggressive  beat, loud guitar with abrupt chord changes, and nihilistic lyrics. Variants  include new wave (more pop-oriented and accessible) and hardcore (char�  acterized by brief, harsh songs played at breakneck speed); the latter con�  tinued to thrive through the 1990s.</p><p>Punnett Vp3n-9t\, Reginald Crundall (b. June 20, 1875, Tonbridge,  Kent, Eng.�d. Jan. 3, 1967, Bilbrook, Somerset) British geneticist.  Through contact with William Bateson he came to support the theories of  Gregor Mendel, and in 1905 he published the first textbook on Mende-  lian genetics. Using poultry and sweet peas, Punnett and Bateson discov�  ered some of the fundamental processes of Mendelian genetics, including  linkage, sex determination, sex linkage, and the first example of nonsexual  chromosome linkage. Punnett demonstrated the value of using sex-linked  plumage-colour factors to distinguish male from female chickens, mak�  ing possible early identification of the less valuable males, a process now  known as autosexing.</p><p>Punt \'punt\ In ancient Egyptian and Greek geography, the southern coast  of the Red Sea and adjacent coasts of the Gulf of Aden, corresponding to  modern coastal Ethiopia and Djibouti. Visited by Egyptian expeditions as  early as 2200 bc, it was a place of ancient legend and fable and Egypt�s  source for incense, ivory, and ostrich feathers. During the reign of Queen  Hatshepsut, an expedition was sent to Punt, and the queen had the details  of the journey recorded on the walls of the Deir el-Bahri temple near  Thebes. Only in the late 4th century bc were the trade routes to Punt opened  to the Greeks.</p><p>pupa \'pyii-p9\ Inactive, nonfeeding stage in the life of insects that  undergo complete metamorphosis. In a protective covering (cocoon or  chrysalis), the larva is transformed into an adult. During pupation, a pro�  cess controlled by hormones, larval structures break down and adult struc�  tures form; wings appeal - for the first time. The adult emerges either by  splitting the pupal skin and chewing its way out or by secreting a fluid  that softens the cocoon.</p><p>puppetry Art of creating and manipulating puppets in a theatrical show.  Puppets are figures that are moved by human rather than mechanical aid.  They may be controlled by one or several puppeteers, who are screened  from the spectators. Varieties include glove (or hand) puppets, rod pup�  pets, shadow puppets, and marionettes (or string puppets). Puppetry had  its beginnings in tribal society and has been part of every civilization.

A Purana traditionally treats five subjects: primary  creation of the universe, secondary creation after periodic annihilation,  genealogy of gods and saints, grand epochs, and histories of the royal  dynasties. Written in narrative couplets, the Purana s date from c. 400 to  c. 1000. The 18 principal surviving Puranas are grouped according to  whether they exalt Vishnu, Shiva, or Brahma. Most popular is the Bhaga-  vata Purana, which treats the early life of Krishna.</p><p>Purari River River, eastern central New Guinea. Rising in the central  highlands of Papua New Guinea, it flows about 290 mi (470 km) to the  Gulf of Papua of the Coral Sea. Its lower course divides into five main  channels that lace through a well-settled swampy delta. It is navigable for  about 120 mi (190 km). Although found and partially charted in 1887, the  river system was not fully traced until the 1930s.</p><p>Purcell Vpor-soL, Henry (b. c. 1659, London, Eng.�d. Nov. 21, 1695,  London) British composer. Little is known of his origins, but he was in the  Chapel Royal choir from boyhood, and he probably studied with Pelham  Humfrey (1647-74) and John Blow (1649-1708). His first known compo�  sition was written at age eight. When his voice changed, he assisted in  keeping the royal instruments in repair and tuning the Westminster Abbey  organ. He became organist there in 1679 and at the Chapel Royal in 1682.  He wrote music in a number of genres. His opera Dido and Aeneas (1689)  is notable for achieving a high degree of dramatic intensity within a narrow  framework. This he followed with the �semi-operas� King Arthur (1691),  The Fairy Queen (1692), and The Indian Queen (1695). He also wrote  much incidental music, some 250 songs, 12 fantasias for viol consort, and  many anthems and services. He is regarded as the greatest English com�  poser after William Byrd and before the 20th century.</p><p>purdah Seclusion of women from public observation by means of con�  cealing clothing (including the veil) and walled enclosures as well as  screens and curtains within the home. The custom seems to have origi�  nated in Persia and was adopted by Muslims during the Arab conquest of  what is now Iraq in the 7th century. The Muslim domination of northern  India led to its adoption by the Hindu upper classes, but it was discarded  by Hindus after the end of British rule in India. The custom of purdah still  continues in many Islamic countries.</p><p>pure culture In microbiology, laboratory culture containing a single  species of organism. A pure culture is usually derived from a mixed cul�  ture (containing many species) by methods that separate the individual  cells so that, when they multiply, each will form an individually distinct  colony, which may then be used to establish new cultures with the assur�  ance that only one type of organism will be present. Pure cultures may  be more easily isolated if the growth medium of the original mixed cul�  ture favours the growth of one organism to the exclusion of others.</p><p>Pure Land Buddhism Devotional cult of the buddha Amitabha. It is  one of the most popular forms of Mahayana Buddhism in East Asia today.  Pure Land schools believe that rebirth in the Western Paradise (the Pure  Land) is given to all those who invoke Amitabha�s name with sincere  devotion. In China the Pure Land cult can be traced back to the 4th cen�  tury, when the scholar Huiyuan (333�416) formed a society of monks and  laymen who meditated on the name of Amitabha. His successors system�  atized and spread the doctrine in the 6th-7th century. The Pure Land  teaching was transmitted to Japan by monks of the Tiantai school.</p><p>purgatory In Roman Catholic doctrine, the condition of those who  have died in a state of grace but have not been purged of sin. These  remaining sins include unforgiven venial sins or forgiven mortal sins.  Souls burdened by such sins must be purified before entering heaven. The  church also teaches that souls in purgatory may be aided by efforts of the  living faithful through prayers, almsgiving, indulgences, and other works.</p><p>The existence of purgatory has been denied as unbiblical by Protestant  churches and most Eastern Orthodox churches.</p><p>purge trials Soviet trials of critics of Joseph Stalin. After the assassina�  tion of Sergey Kirov, prominent Bolsheviks were accused of conspiracy to  remove Stalin from power. In three widely publicized show trials (1936�  38), which presented confessions obtained under torture or fabricated by  the secret police, the accused were found guilty and executed or sent to  prison. Numerous closed, unpublicized trials of Soviet military leaders  were also held and resulted in a massive purge throughout the armed forces.  The trials eliminated such potential rivals and critics of Stalin as Nikolay  Bukharin, Lev Kamenev, Aleksey Rykov, Mikhayl Tukhachevsky, Genrikh  Yagoda, and Grigory Zinovyev but earned worldwide condemnation.</p><p>Purim Vpur-im, pu-'rem\ Jewish festival celebrating the survival of the  Jews marked for death in Persia in the 5th cent bc. According to the Book  of Esther, Haman, chief minister of King Ahasuerus, planned a general  massacre of the Jews and set the date by casting lots. Ahasuerus� wife  Esther interceded for the Jews, and they were allowed to attack their  enemies. The ritual observance begins with a day of fasting on the 13th  of Adar (in February or March), the day before the actual holiday. The  Book of Esther is read in the synagogue, and Jews are enjoined to  exchange gifts and make donations to the poor. Purim is a day of mer�  rymaking and feasting.</p><p>purine \'pyur-,en\ Any of a class of heterocyclic compounds with a two-  ring structure composed of carbon and nitrogen atoms.

Many Puritans joined the Par�  liamentary party during the English Civil War and gained considerable  power, but after the Restoration they were once again a dissenting minor�  ity. Believing themselves chosen by God to revolutionize history, some  Puritans founded settlements in America (see Pilgrims), notably the Mas�  sachusetts Bay Colony. The Puritans of Massachusetts emphasized the  conversion experience, by which the elect experienced the descent of  grace.

It served as  the country�s temporary capital during the Korean War. Pusan is South  Korea�s largest port and second largest city. Administratively, it has the  status of a metropolitan city equal to that of a province. Industries include  shipbuilding and manufacturing.

Born into an  aristocratic family, Pushkin began his literary career while still a student  at the Imperial Lyceum at Tsarskoye Selo (later renamed Pushkin). His  first major work was the romantic poem Ruslan and Ludmila (1820). With  his political verses and epigrams, he became associated with a revolu�  tionary movement that culminated in the unsuccessful Decembrist revolt of  1825. Banished to several provincial locations, he produced a cycle of  romantic narrative poems that confirmed him as the leading Russian poet  of the day and the leader of the Romantic generation of the 1820s. He  also worked on his important historical tragedy, Boris Godunov (1831),  and his central masterpiece, the novel in verse Eugene Onegin (1833).  After Nicholas I allowed him to return to Moscow in 1826, Pushkin aban�  doned his revolutionary sentiments, turning to the figure of Peter the Great  in poems such as The Bronze Horseman (1837). Other works from this  period include the classic short story �The Queen of Spades� (1834) and  the drama The Stone Guest (1839). In his late works the motif of peasant  rebellion is prominent. The object of suspicion in court circles, he died  at age 37 after being forced into a duel. He is often considered his coun�  try�s greatest poet and the founder of modern Russian literature.</p><p>Putin Vpii-tyinV Vladimir (Vladimirovich) (b. Oct. 7, 1952, Len�  ingrad, U.S.S.R.) Russian president (from 1999). Putin served 15 years  with the KGB, including six years in Dresden, East Ger. In 1990 he retired  from active KGB service and returned to Russia to become prorector of  Leningrad State University, and by 1994 he had risen to the post of first  deputy mayor of the city. In 1996 he moved to Moscow, where he joined  the presidential staff as deputy to Pavel Borodin, the Kremlin�s chief  administrator. In July 1998 President Boris Yeltsin made Putin director of  the Federal Security Service (the KGB�s domestic successor). In 1999  Yeltsin appointed Putin prime minister, and on December 31 of that year  Yeltsin stepped down as president in Putin�s favour. Three months later  Putin won a resounding electoral victory, partly the result of his success  in the battle to keep Chechnya from seceding. In his first term he asserted  central control over Russia�s 89 regions and republics and moved to  reduce the power of Russia�s unpopular financiers and media tycoons. The  period was also marked by frequent terrorist attacks by Chechen separat�  ists. Putin easily won reelection in 2004.</p><p>Putnam, Hilary (b. July 31, 1926, Chicago, Ill., U.S.) U.S. philoso�  pher. After receiving his Ph.D. in 1951 he taught at Northwestern Uni�  versity, Princeton University, the Massachusetts Institute of Technology,  and Harvard. Early in his career he was a defender of scientific realism.  In the 1960s he extended the causal theory of reference to natural-kind  and other scientific terms. He is known as the originator of functionalism  in the philosophy of mind, though he later rejected that approach (see phi�  losophy of language). Beginning in the mid-1970s he gradually aban�  doned his earlier scientific realism in favour of a pragmatically oriented  view he called �internal realism.� According to this view, scientific theo�  ries are not true absolutely but only relative to large-scale conceptual  schemes. Among his many works are Philosophical Papers (3 vol., 1975�  83), Reason, Truth, and History (1981), and Pragmatism (1995).</p><p>Putnam, Israel (b. Jan. 7, 1718, Salem Village, Mass.�d.

He served throughout the  French and Indian War and rose to the rank of lieutenant colonel in 1759.  Appointed a major general in the Continental Army in 1775, he fought  with distinction at Bunker Hill, but his troops were defeated at the Battle  of Long Island.

Entering the Con�  tinental Army in 1775, he organized fortifications in Boston and New York  (1776-77) and at West Point (1778), and he fought at the Battle of  Saratoga. In 1783 he was promoted to brigadier general. After the war  he helped found the Ohio Company of Associates to obtain a land grant  for settlement by war veterans; he led the group that founded Marietta,  Ohio (1788).

Acute pyelonephritis is  usually localized and may have no apparent cause. Symptoms include  fever, chills, lower-back pain, and bacteria and white blood cells in the  urine. Treatment with antibiotics requires one to three weeks. Scar tissue  forms, but kidney function is usually not impaired. Chronic pyelonephri�  tis results from repeated bacterial infections, which may have no symp�  toms but destroy more and more tissue over years. If it is diagnosed before  too much function is lost, surgery may help, but uremia, severe infections,  and heart and blood-vessel disorders can lead to death. Dialysis or kidney  transplant sometimes prolongs life.</p><p>Pygmalion In Greek mythology, a king of Cyprus who fell in love with  a statue of Aphrodite.

Beginning with his first novel, V (1963), a complex, cynically absurd  tale that juxtaposes scenes of 1950s hipster life with symbolic images of  the entire century, his works have combined black humour and fantasy to  depict human alienation in the chaos of modem society. The idea of con�  spiracy is central to The Crying of Lot 49 (1966) and to his masterpiece,  Gravity�s Rainbow (1973), an extraordinary novel about the end of World  War II, full of paranoid fantasy, grotesque imagery, and esoteric scientific  and anthropological material.

It is a centre of heavy industry and transportation.</p><p>pyramid Ancient monumental structure constructed of or faced with  stone or brick and having a rectangular base and four sloping triangular  sides meeting at an apex. Pyramids have been built at various times and  places; the best-known are those of Egypt and of Central and South  America. The pyramids of ancient Egypt were royal tombs. Each con�  tained an inner sepulchral chamber that housed the deceased (usually  mummified) ruler, members of his entourage, and artifacts. The rest of the  pyramid complex consisted of a large enclosure, an adjacent mortuary  temple, and a causeway leading down to a pavilion. About 80 royal pyra�  mids survive in Egypt, the greatest being those at Giza. American pyra�  mids include the pyramids of the Sun and Moon at Teotihuacan, the  Castillo at Chichen Itza, and various Inca and Chimu structures in Andean  settlements. These pyramids were generally built of earth and faced with  stone; they are typically stepped pyramids and are topped by a platform  or temple structure used for rituals, including human sacrifice.</p><p>Pyramus and Thisbe Vpir-9-m9s... , thiz-be\ Hero and heroine of a  Babylonian love story related in Ovid�s Metamorphoses.

Pyrite has frequently fooled prospec�  tors into thinking they had discovered gold. Pure pyrite (FeS 2 ) contains  47% iron and 53% sulfur, by weight. Pyrite is used commercially as a  source of sulfur, particularly for the production of sulfuric acid. Because  there are much better sources of iron, it is not generally used as an iron ore.  For many years Spain was the largest producer; other countries include  Japan, the U.S., Canada, Italy, Norway, Portugal, and Slovakia.</p><p>pyrometer \pl-'ra-m3-t3r\ Instrument for measuring relatively high tem�  peratures, as in furnaces. Most pyrometers work by measuring radiation  from the body whose temperature is to be measured (radiation devices have  the advantage of not having to touch the material being measured). Optical  pyrometers measure the temperature of glowing bodies by comparing them  visually with an incandescent filament of known temperature whose tem�  perature can be adjusted. In resistance pyrometers, a fine wire is put in con�  tact with the object; the instrument converts the change in electrical  resistance caused by heat to a reading of the temperature of the object.</p><p>pyroxene \pl-'rak-,sen\ A group of important rock-forming silicate min�  erals of variable composition, among which calcium-, magnesium-, and  iron-rich varieties predominate. Common pyroxenes belong to either the  low-calcium enstatite-(ortho)ferrosilite series, (Mg,Fe)Si0 3 , or the high-  calcium diopside-hedenbergite series, Ca(Mg,Fe)Si 2 0 6 . Rare pyroxenes  include jadeite, aegirine, and johannsenite. See also enstatite.</p><p>pyroxenite \pi- , rak-so- l n!t\ Dark medium- to coarse-grained igneous  rock that consists chiefly of pyroxene.

After being allied to Demetrius and taken hostage, he was  befriended by Ptolemy I Soter and restored to his kingdom. In 281 he was  asked for help against Rome by the Greek enclave of Tarentum (Taranto)  and won costly victories at Heraclea and Ausculum. Crossing to Sicily,  he conquered most of the Punic territory, but the Greek Sicilians revolted  against his despotism. He suffered serious losses on his return to Italy  (275) but defeated Antigonus II Gonatas in Macedonia (274) and became  king there. He died in a skirmish in Argos trying to help Sparta. His costly  victories gave rise to the term �Pyrrhic victory.�</p><p>Pythagoras \p3-'tha-g3-r3s\ (b. c. 580 bc, Samos, Ionia�d. c. 500,  Metapontum, Lucania) Greek philosopher and mathematician. He estab�</p><p>lished a community of followers in Croton who adhered to a way of life  he prescribed. His school of philosophy reduced all meaning to numeri�  cal relationships and proposed that all existing objects are fundamentally  composed of form and not material substance. The principles of  Pythagoreanism, including belief in the immortality and reincarnation of  the soul and in the liberating power of abstinence and asceticism, influ�  enced the thought of Plato and Aristotle and contributed to the develop�  ment of mathematics and Western rational philosophy. The proportions of  musical intervals and scales were first studied by Pythagoras, and he was  the first influential Western practitioner of vegetarianism. None of his writ�  ings survive, and it is difficult to distinguish the ideas he originated from  those of his disciples. His memory is kept alive partly by the Pythagorean  theorem, probably developed by his school after he died.</p><p>Pythagorean \p9-,tha-g3-'re-3n\ theorem Rule relating the lengths  of the sides of a right triangle. It says that the sum of the squares of the  lengths of the legs is equal to the square of the length of the hypotenuse  (the side opposite the right angle). That is, a 2 + b 2 = c 2 , where c is the  length of the hypotenuse. Triads of whole numbers that satisfy it (e.g., 3,  4, and 5) are called Pythagorean triples. See also law of cosines; law of  sines.</p><p>Pythagoreanism Xps-.tha-gs-'re-s-.ni-zsnA Philosophical school,  probably founded by Pythagoras c. 525 bc. It originated as a religious  brotherhood or an association for the moral reformation of society; broth�  ers were sworn to strict loyalty and secrecy. The brotherhood had much  in common with the Orphic communities (see Orphism), which sought by  rites and abstinence to purify the believer�s soul and enable it to escape  from the �wheel of birth.� Pythagoreanism held that reality, at its deepest  level, is mathematical, that philosophy can be used for spiritual purifica�  tion, that the soul can rise to union with the divine, and that certain sym�  bols have mystical significance. It was the first important Western system  of thought to advocate vegetarianism. The school became extinct in the  mid-4th century.</p><p>Pythian \'pi-the-an\ Games In ancient Greece, various athletic and  musical competitions held in honour of Apollo, chiefly those at Delphi. The  games were held from before the 5th century bc to the 4th century ad.  They took place in August of the third year of each Olympiad (the four-  year period between Olympic Games). Events were similar to those of the  ancient Olympics.</p><p>python \'pl-,than\ Any of 28 species (family Pythonidae, sometimes a  subfamily of Boidae) of sluggish, docile, nonvenomous snakes found in  tropical and temperate regions. Except for one Central American species  {Loxocemus bicolor ), pythons are found from western Africa to China,  Australia, and the Pacific islands. Pythons feed on birds and mammals,  killing them by constriction. Most are found near water; some are arbo�  real. Unlike boas, pythons lay eggs (15-100, depending on body size).  The Asian reticulated python (.Python reticulatus) may be the world�s  longest snake (the anaconda is heavier); specimens over 30 ft (9 m) long  have been recorded.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Qadariya &#x25BA; Qatar I 1571</p><p>Qadariya \,ka-d3-'re-3\ In Islam, adherents of the doctrine of free will.

As a captain in the army, he  led the 1969 coup that deposed King Idris I. He espoused his  own form of Islamic socialism, and his foreign policy was  anti-Western and anti-Israel. In 1970 he closed U.S. and  British military bases and expelled Italians and Jews.</p><p>He banned alcoholic beverages and gambling and in  1973 nationalized the oil industry. He made unsuc�  cessful attempts to unify Libya with other coun�  tries.

Its members supported Muslim fighters during the Afghan war of 1979�  89; afterward the organization dispersed but continued to oppose secu�  larized Muslim regimes and foreign (notably U.S.) presence in Islamic  lands. It staged numerous terrorist attacks, including the bombing of the  World Trade Center in 1993, the destruction of two U.S. embassies in  Africa in 1998, and a suicide bomb attack against the U.S. warship Cole  in 2000. During that time it merged with other Islamic extremist organi�  zations and eventually reestablished its headquarters in TAUBAN-controlled  Afghanistan, where it trained thousands of Muslim militants. In 2001, 19  such militants staged the September 11 attacks. The U.S. and allied forces  responded by attacking Taliban and al-Qaeda forces in Afghanistan, kill�  ing and capturing thousands and driving the remainder into hiding.</p><p>Qajar \ka-'jar\ dynasty (1794-1925) Ruling dynasty of Iran.

During the Eastern Zhou  dynasty, Qi was the first state to fully institute a uniform tax system, a  central army, and a centralized bureaucracy based on talent rather than  hereditary rank. It formed a league of states in 651 bc to stave off inva�  sions from the north and south, but its hegemony was short-lived. In 221  bc it was absorbed into the Qin dynasty.</p><p>q&gt; or ch'i Vche\ In Chinese philosophy, the ethereal substance of which  everything is composed. Early Daoist philosophers and alchemists  regarded it as a vital force associated with breath and bodily fluids and  sought to control its movement within the body in order to achieve lon�  gevity and spiritual power. Manipulation of qi is central to Chinese medi�  tation, medicine, and martial arts.

Hongli (b. Sept. 25, 1711, China�d. Feb. 7, 1799, Beijing) Fourth  emperor of the Qing dynasty in China. His reign (1735-96) was one of  the longest in Chinese history. China�s boundaries reached their greatest  extent, encompassing Mongolia, Tibet, Nepal, Taiwan, and portions of  Central Asia. Qianlong sponsored a compilation of the Confucian Clas�  sics (see Five Classics); the compilation�s descriptive catalog is still used  today. At the same time, he ordered that all books containing anti-Manchu  sentiments be expurgated or destroyed; some 2,600 titles were lost. He  enjoyed excellent personal relationships with Jesuit missionaries in  Beijing, though Roman Catholic preaching remained officially forbidden.  In the first half of his reign, agriculture made great strides and was supe�  rior to that in much of Europe. Taxes were light and education was wide�  spread, even among the peasantry. Subsequently, military expeditions and  increasing governmental corruption permanently harmed the dynasty,  sowing the seeds for its decline in the 19th century.

Legend has it that a qilin appeared to the pregnant mother of  Confucius.</p><p>Qin dynasty or Ch'in \'chin\ dynasty (221-207 bc) Dynasty that  established the first great Chinese empire. The Qin (from which the name  China is derived) established the approximate boundaries and basic  administrative system that all subsequent dynasties were to follow. Qin  accomplishments include standardizing the Chinese writing system and  building the Great Wall; the dynasty is also notorious for the �Qin bib-  liocaust,� in which all nonutilitarian books were ordered burned. Due to  its harshness, the dynasty outlasted its first emperor, Shihuangdi, by only  three years; it was beset by rebellion and succeeded by the Han dynasty.</p><p>Qin Hui or Ch'in Kuei Vchin-kii-'iA (b. 1090, Jiangning, Jiangsu prov�  ince, China�d. 1155, Hangzhou, Zhejiang province) Chief counselor to  the Southern Song emperor Gaozong.

The name Qing  was first applied to the dynasty established by the Manchu in 1636 in  Manchuria and then applied by extension to their rule in China. During  the Qing dynasty, China�s territory and population expanded tremen�  dously. Cultural attitudes were strongly conservative and Neo-  Confucianism was the dominant philosophy. The arts flourished: literati  painting was popular, novels in the vernacular developed substantially,  and jingxi (Peking opera) developed. Qing porcelain, textiles, tea, paper,  sugar, and steel were exported to all parts of the world. Military cam�  paigns in the latter part of the 18th century depleted government finances,  and corruption grew. These conditions, combined with population pres�  sures and natural disasters, led to the Opium Wars and the Taiping and Nian  rebellions, which in turn so weakened the dynasty that it was unable to  rebuff the demands of foreign powers. The dynasty ended with the repub�  lican revolution of 1911 and the abdication of the last emperor in 1912.</p><p>Qinghai DrCh'ing-hai conventional Tsinghal Province (pop., 2000  est.: 5,180,000), west-central China.

In this view, pri�  mary qualities, such as shape, quantity, and motion, are genuine properties  of things that are describable by mathematics, whereas secondary quali�  ties, such as odour, taste, sound, and colour, exist only in human con�  sciousness.</p><p>Quant, Mary (b.

Quantrill�s Raiders were made an official troop by the Con�  federates in 1862. In 1863 Quantrill and his group of about 450 men  sacked the free-state town of Lawrence, Kan., killing 150 people. They  later defeated a Union detachment, killing 90 soldiers. Quantrill was mor�  tally wounded in a raid into Kentucky.</p><p>quantum In physics, a discrete natural unit, or packet, of energy, charge,  angular momentum, or other physical property. Light, for example, which  appears in some respects as a continuous electromagnetic wave, on the  submicroscopic level is emitted and absorbed in discrete amounts, or  quanta; for light of a given wavelength, the magnitude of all the quanta  emitted or absorbed is the same in both energy and momentum. These  particlelike packets of light are called photons, a term also applicable to  quanta of other forms of electromagnetic energy such as X rays and gamma  rays. Submicroscopic mechanical vibrations in the layers of atoms com�  prising crystals also give up or take on energy and momentum in quanta  called phonons. See also quantum mechanics.</p><p>quantum chromodynamics (QCD) Theory that describes the  action of the strong force. The strong force acts only on certain particles,  principally quarks that are bound together in the protons and neutrons of  the atomic nucleus, as well as in less stable, more exotic forms of matter.  Quantum chromodynamics has been built on the concept that quarks inter�  act via the strong force because they carry a form of �strong charge,�  which has been given the name �colour.� The three types of charge are  called red, green, and blue, in analogy to the primary colours of light,  though there is no connection with the usual sense of colour.</p><p>quantum computing Experimental method of computing that makes  use of quantum-mechanical phenomena. It incorporates quantum theory  and the uncertainty principle. Quantum computers would allow a bit to store  a value of 0 and 1 simultaneously. They could pursue multiple lines of  inquiry simultaneously, with the final output dependent on the interfer�  ence pattern generated by the various calculations. See also DNA com�  puting, QUANTUM MECHANICS.</p><p>quantum electrodynamics (QED) Quantum theory of the interac�  tions of charged particles with the electromagnetic field. It describes the  interactions of light with matter as well as those of charged particles with  each other. Its foundations were laid by P. A. M. Dirac when he discov�  ered an equation describing the motion and spin of electrons that incor�  porated both quantum mechanics and the theory of special relativity. The  theory, as refined and developed in the late 1940s, rests on the idea that  charged particles interact by emitting and absorbing photons. It has  become a model for other quantum field theories.</p><p>quantum field theory Theory that brings quantum mechanics and  special relativity together to account for subatomic phenomena. In particu�  lar, the interactions of subatomic particles are described in terms of their  interactions with fields, such as the electromagnetic field. However, the  fields are quantized and represented by particles, such as photons for the  electromagnetic field. Quantum electrodynamics is the quantum field theory  that describes the interaction of electrically charged particles via electro�  magnetic fields. Quantum chromodynamics describes the action of the  strong force. The ELECTROWEAK theory, a unified theory of electromagnetic  and weak forces, has considerable experimental support, and can likely be  extended to include the strong force. Theories that include the gravita�  tional force (see gravitation) are more speculative. See also grand unified  THEORY, UNIFIED FIELD THEORY.</p><p>quantum mechanics Branch of mathematical physics that deals with  atomic and subatomic systems. It is concerned with phenomena that are  so small-scale that they cannot be described in classical terms, and it is  formulated entirely in terms of statistical probabilities. Considered one of  the great ideas of the 20th century, quantum mechanics was developed  mainly by Niels Bohr, Erwin Schrodinger, Werner Heisenberg, and Max  Born and led to a drastic reappraisal of the concept of objective reality. It  explained the structure of atoms, atomic nuclei (see nucleus), and mol�  ecules; the behaviour of subatomic particles; the nature of chemical bonds  (see bonding); the properties of crystalline solids (see crystal); nuclear  energy; and the forces that stabilize collapsed stars. It also led directly to  the development of the laser, the electron microscope, and the transistor.</p><p>Qu'Appelle \kwa-�pel\ River River, southern Saskatchewan, Canada.  It is about 270 mi (435 km) long and flows east through several lakes and  Indian reservations and across the Manitoba border into the Assiniboine  River. Its French name, meaning �who calls,� derived from its Cree Indian</p><p>name Kah-tep-was (�River That Calls�), referring to the cries of a leg�  endary spirit supposedly haunting its waters. Once a fur-trapping region,  its basin is now farmed for wheat.</p><p>quarantine Detention of humans or animals suspected to have com�  municable disease until they are proved free of infection. The term is often  used interchangeably with isolation (separation of a known infected indi�  vidual from healthy ones until the danger of transmission passes). It  derives from the 40-day ( quarantina ) isolation period instituted in an  attempt to prevent spread of plague in the Middle Ages. Though appro�  priate in some cases (e.g., diphtheria), it is ineffective for diseases that are  spread by other means (e.g., plague) or are contagious before symptoms  appear. In some cases, contacts (e.g., the family of a hepatitis patient) are  notified, educated on precautions, and monitored for development of ill�  ness. Quarantine is more often applied to animals (e.g., for rabies).</p><p>quark Any of a group of subatomic particles thought to be among the  fundamental constituents of matter�more specifically, of protons and  neutrons. The concept of the quark was first proposed by Murray Gell-  Mann and George Zweig (b. 1937); its name was taken from James Joyce�s  novel Finnegans Wake. Quarks include all particles that interact by means  of the strong force. They have mass and spin, and they obey the Pauli exclu�  sion principle. They have never been resolved into smaller components, and  they never occur alone. Their behaviour is explained by the theory of  quantum chromodynamics, which provides a means of calculating their  basic properties. There are six types of quarks, called up, down, strange,  charm, bottom, and top. Only the up and down quarks are needed to make  protons and neutrons; the others occur in heavier, unstable particles.</p><p>Quarles, Francis (baptized May 8, 1592, Romford, Essex, Eng.�d.  Sept. 8, 1644, London) English religious poet. Quarles is remembered for  his Emblemes (1635), the most notable of English-language emblem  books (collections of symbolic pictures, usually with verse and prose). Its  success led him to produce another, Hieroglyphikes of the Life of Man  (1638). Printed together in 1639, they formed perhaps the most popular  volume of verse of the 17th century. He also wrote Enchiridion (1640), a  highly popular book of aphorisms.</p><p>quarter horse Breed of light horse developed in the U.S. from Thor�  oughbred, Morgan, American saddlebred, and other stock as a quarter-mile  racer. Though overshadowed by the Thoroughbred, it found a place in the  western and southwestern U.S. as a stock horse (see cutting horse). Mod�  em quarter horses are short and stocky, with a muscular build and a deep,  broad chest. They are noted for fast starting, turning, and stopping abil�  ity, short-distance speed, and intelligence. They stand 14.3-16 hands  (57-64 in., 145-163 cm) high, weigh 950-1,200 lbs (431-544 kg), and  have a calm, cooperative temperament.</p><p>quarter-horse racing Racing of quarter horses. It originated among  British settlers in Virginia shortly after Jamestown was established in  1607. The course was traditionally a quarter-mile (400 m); today there  are 11 officially sanctioned races, ranging from 220 to 870 yd (201 to 796  m). Timing is to the nearest .01 second.</p><p>quartermaster Officer who oversees arrangements for the quartering  and movement of troops. The office dates at least to the 15th century in  Europe. The French minister of war under Louis XIV created a quarter�  master general�s department that dotted the countryside with strategically  located stockpiles of food, forage, ammunition, and equipment. By the  18th century his duties in some European countries included coordinat�  ing marches and deployments and drafting operational orders; in the U.S.  he remained a specialized administrative and logistical functionary until  1962, when the Quartermaster Corps was absorbed by other agencies.</p><p>quartz Second most abundant mineral (after feldspar) in the Earth�s  crust, present in many rocks. Quartz, which consists of silica, or silicon  dioxide (Si0 2 ), has great economic importance. Many varieties are gem�  stones, including amethyst, citrine, smoky quartz, and rose quartz. Sand�  stone, composed mainly of quartz, is an important building stone. Large  amounts of quartz sand (or silica sand) are used in the manufacture of  glass and ceramics and for molds in metal casting. Crushed quartz is used  as an abrasive in sandpaper; silica sand is employed in sandblasting; and  sandstone is used whole to make whetstones, millstones, and grindstones.  Silica glass (or fused quartz) is used in optics to transmit ultraviolet light.  Tubing and various vessels of fused quartz have important laboratory  applications, and quartz fibres are employed in extremely sensitive weigh�  ing devices.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>quartzite &#x25BA; Queen Anne's lace I 1575</p><p>quartzite Sandstone that has been converted into a solid quartz rock.  Quartzites are usually white; they fracture smoothly and break up into  rubble under frost action. Sandstone may be converted to quartzite by  precipitation of silica from waters below the Earth�s surface; such rocks  are called orthoquartzites, whereas those produced by recrystallization  (metamorphism) are metaquartzites. Because they weather slowly, they tend  to project as hills or mountain masses. Many prominent ridges in the  Appalachian Mountains are composed of quartzite. Pure quartzites are a  source of silica for metallurgical purposes and for the manufacture of  silica brick. Quartzite is also quarried for paving and roofing materials.</p><p>quasar Vkwa-,zar\ in full quasi-stellar radio source Any of a</p><p>class of enigmatic cosmic objects of high luminosity and strong radio  emission observed at extremely great distances; also, a closely related  object that has the same optical appearance but does not emit radio waves,  i.e., a so-called quasi-stellar object (QSO). Most quasars exhibit very large  redshifts, suggesting that they are moving away from Earth at tremendous  speeds (approaching the speed of light); they thus are some of the most  distant known objects in the universe. Quasars are no more than a light-  year or two across but as much as 1,000 times more luminous than a giant  galaxy having a diameter of 100,000 light-years; their extreme brightness  allows them to be observed at distances of more than 10 billion light-  years. Many investigators attribute such energy generation to matter spi�  raling at high velocity into a supermassive black hole (millions or billions  of times as much mass as the Sun) at the centre of a distant galaxy.

The Quaternary follows the  Tertiary Period and is the more recent of the two periods of the Cenozoic Era.  The Quaternary is subdivided into the Pleistocene Epoch and the Holocene  Epoch and is characterized by major cyclical changes of climate on a global  scale. These led to repeated invasions of vast areas by ice sheets. Its major  biologic feature is the evolution and dispersion of humans. The dramatic  changes of climate and environment in the Quaternary led to high rates of  evolution and extinction, particularly among the mammals. The extinction  of many large mammals toward the end of the last ice age may also be  related to the rapid territorial expansion of humans.</p><p>Quayle, (James) Dan(forth) (b.

It is bounded  on the north by Hudson Strait and Ungava Bay, on the east by Labrador,  on the southeast by the Gulf of St. Lawrence and New Brunswick, on the  south by the U.S. (Maine, New Hampshire, Vermont, and New York), and  on the west by Ontario and by Hudson Bay. Its capital is Quebec city. The  original inhabitants were Inuit (see Eskimo) and members of Algonquin,  Cree, and other Indian tribes. Settled by the French in the early 17th cen�  tury, the area was lost to the British in the French and Indian War, but the  struggle for authority between the French and British groups led to a  rebellion by French Canadians in 1837. The rebellion was quelled and in  1867 Quebec (formerly Canada East) united with New Brunswick and  Nova Scotia to form the Dominion of Canada. Most of the population of  Quebec is of French descent. Various movements calling for Quebec�s  independence from the rest of Canada continued throughout the 20th cen�  tury; the Parti Quebecois won provincial elections in 1976, but its inde�</p><p>pendence referendum was defeated in 1980.

Inland from the Great Dividing Range, which runs the entire length  of the state, mining and cattle ranching are important. Capt. James Cook  charted the coast in 1770. In the 19th century the state housed several  penal colonies and drew settlers to mine its gold. It became a constituent  state in 1901 when the Commonwealth of Australia was proclaimed.</p><p>quenching Rapid cooling, as by immersion in oil or water, of a metal  object from the high temperature at which it is shaped. Quenching is usu�  ally done to maintain mechanical properties that would be lost with slow  cooling. It is commonly applied to steel objects, to which it gives hard�  ness. The quenching media and the type of agitation during quenching are  selected to obtain specified physical properties with minimum internal  stresses and distortions. Oil is the mildest medium, and salt brine has the  strongest quenching effect. In special cases, steel is cooled and held for  some time in a molten salt bath, which is kept at a temperature either just  above or just below the temperature where martensite begins to form.  These two heat treatments, called martempering and austempering, both  result in even less distortion of the metal. Copper objects hardened by  hammering or other deformation at ordinary temperatures can be restored  to malleability by heating and quenching. See also tempering.</p><p>Queneau Mra-'noN, Raymond (b.

Founded  by the Otomi Indians, it was incorporated into the Aztec empire in 1446.  Brought under Spanish control in 1531, it became an important supply  centre for the rich mining districts of Guanajuato and Zacatecas. Emperor  Maximilian was executed there in 1867 after his defeat by the forces of  Benito Juarez. The Mexican Constitution of 1917 was written in Queretaro.  It is the site of one of Mexico�s oldest and largest cotton factories; tex�  tiles and pottery are also produced there.</p><p>Queretaro \ka-'ra-ta-,ro\ State (pop., 2000: 1,404,306), central Mexico.

He served as  consulting physician to Louis XV at Versailles, where he developed an  interest in economics. In his Tableau economique (1758), he described  the relationship between the different economic classes of society and the  flow of payments among them, and he developed the concept of economic  equilibrium used by many later economic analysts. An advocate of laissez-  faire economic policy, he became the intellectual leader of the physiocrat,  the first systematic school of political economy.</p><p>Quetelet \ket-'le\, (Lambert) Adolphe (Jacques) (b.

It was  the sacred bird of the ancient Mayas and Aztecs. Today the quetzal, found  in remote parts of cloud forests from southern Mexico to Bolivia, is the  national emblem of Guatemala (whose monetary unit is the quetzal). The  resplendent, or Guatemalan, quetzal is about 50 in. (125 cm) long. Long  blue-green plumes cover the tail; the breast and head, with a rounded  hairlike crest, are gold-green; the blue back has a curly gold-tinged  mantle; and the belly is red.

For the Toltecs he was the god  of the morning and evening star. The  Aztecs revered him as the patron of  priests, the inventor of the calendar  and of books, and the protector of  goldsmiths and other craftsmen. He  was also identified with the planet  Venus and was a symbol of death and  resurrection. One myth held that he  was a white priest-king who sailed  away on a raft made of snakes. The  belief that he would someday return  from the east led Montezuma II to  regard Hernan Cortes as the fulfill�  ment of the prophecy.</p><p>queuing \'kyu-iq\ theory Study  of the behaviour of queues (waiting  lines) and their elements.

Quezon fought in the Philippine-American War but became convinced  after the Philippines� defeat that the only way to independence was  through cooperation with the U.S. He served in the Philippine Assembly  (1907-09). As the Philippines� representative in the U.S. House of Rep�  resentatives (1909-16), he played a major role in obtaining Congress�s  pledge of independence for the Philippines (1916) and fought for passage  of the Tydings-McDuffie Act (1934), which laid out a timetable for inde�  pendence. He became president of the Commonwealth (a precursor to the  independent republic) in 1935 and was reelected in 1941; when Japan  occupied the Philippines in 1942, he formed a government-in-exile in the  U.S. He did not live to see full independence for the Philippines.

Quicksand is usually  found in a hollow at the mouth of a large river or along a flat stretch of  stream or beach where pools of water become partly filled with sand and  an underlying layer of stiff clay or other dense material prevents drain�  age. Mixtures of sand, mud, and vegetation in bogs often act like true  quicksands. Any sand may become �quick� if its effective weight is being  carried by water between the grains. In that case, even a footstep may  collapse the loose structure. The sand-water suspension is denser than an  animal or human body, so the body cannot sink below the surface, but  struggling may lead to loss of balance and drowning.</p><p>quicksilver See mercury</p><p>Quiller-Couch, Sir Arthur (Thomas) (b.

The layer of wool, cotton,  or other stuffing provides insulation; the stitching keeps the stuffing evenly  distributed and also provides opportunity for artistic expression. Quilting  has long been used for clothing in many parts of the world, especially in  the Far and Middle East and the Muslim regions of Africa. It reached its  fullest development in the U.S., where it was at first popularly used for  petticoats and comforters. By the end of the 18th century the U.S. quilt  had distinctive features, such as coloured fabric sewn on the outer layers  (applique) and stitching that echoed the applique pattern.

He produced highly origi�  nal and important work in several areas of philosophy, including episte�  mology, logic, ontology, and the philosophy of language. He was known  for rejecting epistemological foundationalism in favour of what he called  �naturalized epistemology,� whose modest task is merely to give a psy�  chological account of how scientific knowledge is obtained. Though influ�  enced by the logical positivism of Rudolf Carnap and other members of the  Vienna Circle, he famously rejected one of their cardinal doctrines, the  analytic-synthetic distinction. In ontology he rejected the existence of prop�  erties, propositions, and meanings as ill-defined or scientifically useless.  He was also known for his behaviourist account of language learning and  for his thesis of the �indeterminacy of translation,� according to which  there can be no �fact of the matter� about which of indefinitely many pos�  sible translations of one language into another is correct. His many books  include Word and Object (1960), The Roots of Reference (1974), and an  autobiography.

After appearing on Broadway  in A Streetcar Named Desire, he returned to Hollywood, where he won  Academy Awards for his supporting roles in Viva Zapata! (1952) and Lust  for Life (1956). He was noted for his earthy masculinity and acted in over  100 other films, notably Federico Fellini�s La strada (1954), Requiem for  a Heavyweight (1962), and Zorba the Greek (1964).

Originally created as a ter�  ritory from parts of YucatAn and Campeche states, it became a state in 1974.  It is the site of many Maya ruins. Its main products are chicle (for chew�  ing gum) and a small amount of copra (for producing coconut oil); the  latter is produced on the coast near the island of Cozumel (where Hernan  Cortes landed in 1519), which is now a popular tourist destination.</p><p>Quinte Vkwin-te\, Bay of Arm of Lake Ontario, southeastern Ontario,  Canada.

In 1934 he accompanied Man�  uel Quezon to the U.S. to secure passage of the Tydings-McDuffie Act,  which set a date for Philippine independence. He became vice president  to Manuel Roxas after independence, succeeding to the presidency on  Roxas�s death in 1948.

Quotas are more effective than tariffs in restricting  trade, since they limit the availability of goods rather than simply increas�  ing their price. By limiting foreign goods, a quota aims to allow domes�  tic goods to compete more successfully, though the price of the goods may  also rise. Quotas restricting trade were first imposed on a large scale dur�  ing World War I. In the 1920s, quotas were progressively abolished and  replaced by tariffs, but their use was revived in the wave of protectionism  set off by the Great Depression.

The book, first compiled in its authoritative form in the 7th  century, consists of 114 chapters (sGrahs) of varying length, written in  Arabic. The earliest surahs call for moral and religious obedience in light  of the coming Day of Judgment; the ones written later provide directives  for the creation of a social structure that will support the moral life called  for by God. The Qur�an also provides detailed accounts of the joys of  paradise and the terrors of hell. Muslims believe that the God who spoke  to Muhammad is the God worshiped by Jews and Christians but that the  revelations received by those religions are incomplete. Emphasis on the  stem justice of God is tempered by frequent references to his mercy and  compassion. The Qur�an demands absolute submission ( islam ) to God and  his word, and it serves as the primary source of Islamic law. It is regarded  as immutable in both form and content; traditionally translation was for�  bidden.

Oct. 9, 1906, near Asyut, Egypt�d. Aug. 29, 1966,  Cairo) Egyptian writer who was one of the foremost figures in modern  Sunnite Islamic revivalism. He was from a family of impoverished rural  notables. For most of his early life he was a schoolteacher. Originally an  ardent secularist, he came, over time, to adopt many Islamist views. Fol�  lowing a brief period studying in the U.S. (1948-50), he became con�  vinced of the corruption of Western secularism and on his return to Egypt  joined the Muslim Brotherhood. He was at first on good terms with the  revolutionary regime of Gamal Abdel Nasser but was imprisoned (1954-  64) along with other Brotherhood leaders on charges of sedition. His  prison years were his most productive. The brutal treatment he received  convinced him that Egypt, like the West, was corrupt, and, drawing (often  freely) on the work of early Muslim scholars such as I bn Taymiyyah, he  argued that much of modern Muslim society had fallen in apostasy and  was, therefore, a legitimate target of jihad. He penned these ideas in sev�  eral books, including Signposts in the Road (1964), which became a tem�  plate for modern Sunnite militancy. Released from prison in 1964, he was  soon rearrested, tried for treason, and executed.</p><p>Qwaqwa Vkwa-,kwa\ Former black enclave, South Africa. It bordered  Lesotho and the province of Natal.

In 1530 he left the  Benedictines to study medicine, a profession he would follow the rest of  his life. He became a significant humanist scholar, publishing  translations of Hippocrates and Galen. His fame rests on the  five comic novels (one of doubtful authenticity) known  collectively as Gargantua and Pantagruel, including the  masterpieces Pantagruel (1532) and Gargantua (1534)  as well as Le Tiers Livre (1546; �The Third Book�), his  most profound work. These works display a delight in  words, a mastery of storytelling, and deep humanist  learning in a mosaic of scholarly, literary, and scientific  parody that is unlike any previous work in French. The  books were banned by civil and church authorities for their  satirical content and earthy humour, but they were neverthe�  less read throughout Europe. Throughout his career, Rabe�  lais owed his freedom to the protection of powerful  patrons.</p><p>Rabi Yra-be\, l(sidor) l(saac) (b. July 29,  1898, Rymanow, Austria-Hungary�d. Jan. 11,  1988, New York, N.Y., U.S.) Polish-born U.S.  physicist. He earned his Ph.D. at Columbia University, where he later  taught physics (from 1929). In 1940-45 at the Massachusetts Institute of  Technology he led a group of scientists who helped develop radar, and  he succeeded J. Robert Oppenheimer as chairman of the Atomic Energy  Commission�s General Advisory Committee (1952-56). He was the first  to propose the joint European laboratory CERN, and he helped found New  York�s Brookhaven National Laboratory. His method for measuring the  magnetic properties of atoms, atomic nuclei, and molecules (1937) led to  the atomic clock, the maser, the laser, magnetic resonance imaging, and  the central technique for molecular and atomic beam experimentation; it  also won him a 1944 Nobel Prize.</p><p>rabies \'ra-,bez\ Acute, usually fatal infectious disease of warm-blooded  animals that attacks the central nervous system. It is spread by contact with  an infected animal�s saliva, usually from a bite. The rhabdovirus that  causes it spreads along nerve tissue from the wound to the brain. Symp�  toms usually appear four to six weeks later, often beginning with irrita�  bility and aggressiveness. Wild animals lose their fear of humans and are  easily provoked to bite, as are pets. Depression and paralysis soon follow.  Death usually comes three to five days after symptoms begin. In humans,  death can result from a seizure in the early phase even before symptoms  of central nervous system depression develop. One name for rabies,  hydrophobia (�fear of water�), comes from painful throat contraction on  trying to swallow. If not treated in time (within a day or two) with a serum  containing antibodies and then a series of vaccinations, rabies in humans  is almost always fatal. Immediate cleansing of animal bites with soap and  water can remove much of the virus.</p><p>Rabin \r3-'ben\, Yitzhak (b. March 1, 1922, Jerusalem�d. Nov. 4,  1995, Tel Aviv-Yafo, Israel) First native-born prime minister of Israel. He  fought in the first Arab-Israeli War and became chief of staff in 1964. His  strategies helped win the Six-Day War in 1967. After retiring from the  army (1968), he served as ambassador to the U.S. (1968-73). As head of  the Israel Labour Party, he twice served as prime minister (1974-77, 1992�  95). During his first tenure, he secured a cease-fire with Syria in the Golan  Heights and ordered the raid at Entebbe, Ugan. (see Entebbe raid). As  defense minister (1984-90) he responded forcefully to the Palestinian first  intifadah. In 1993 secret negotiations with the Palestinians yielded a politi�  cal settlement that called for limited Palestinian self-rule in the Gaza Strip  and the West Bank, for which he shared the 1994 Nobel Prize for Peace  with Shimon Peres and Yasir �Arafat. He was assassinated by a right-wing  Jewish extremist.</p><p>raccoon or ringtail Any of seven species of omnivorous, nocturnal  carnivores (genus Procyon, family Procyonidae) characterized by a bushy,</p><p>Eastern cottontail rabbit (Sylvilagus  flor idan us).</p><p>STEVE AND DAVE MASLOWSKI</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>race &#x25BA; Rackham I 1581</p><p>ringed tail and a black mask on the  face. The North American raccoon  (P. lotor ) has a stout body, short legs,  pointed muzzle, and small erect ears.</p><p>It is 30-36 in. (75-90 cm) long,  including the 10-in. (25-cm) tail, and  weighs over 22 lb (10 kg). The  shaggy, coarse fur is iron-gray to  blackish. The feet resemble slender  human hands. Raccoons eat arthro�  pods, rodents, frogs, berries, fruit,  and plants; in towns and cities they  thrive on garbage. They prefer woods  near water and usually live in hollow  trees. The crab-eating raccoon (P  cancrivorus ) of South America is  similar but has coarser fur.</p><p>race Term once commonly used in  physical anthropology to denote a  division of humankind possessing traits that are transmissible by descent  and sufficient to characterize it as a distinct human type (e.g., Caucasoid,  Mongoloid, Negroid). Today the term has little scientific standing, as older  methods of differentiation, including hair form and body measurement,  have given way to the comparative analysis of DNA and gene frequen�  cies relating to such factors as blood typing, the excretion of amino acids,  and inherited enzyme deficiencies. Because all human populations today  are extremely similar genetically, most researchers have abandoned the  concept of race for the concept of the cline, a graded series of differences  occurring along a line of environmental or geographical transition. This  reflects the recognition that human populations have always been in a state  of flux, with genes constantly flowing from one gene pool to another,  impeded only by physical or ecological boundaries. While relative isola�  tion does preserve genetic differences and allow populations to maximally  adapt to climatic and disease factors over long periods of time, all groups  currently existing are thoroughly �mixed� genetically, and such differ�  ences as still exist do not lend themselves to simple typologizing. �Race�  is today primarily a sociological designation, identifying a class sharing  some outward physical characteristics and some commonalities of culture  and history. See also climatic adaptation, ethnic group, racism.</p><p>racemate \ra-'se-,mat\ Mixture of equal quantities of two enantiomers,  substances whose molecular structures are mirror images of one another  (see isomer). The two enantiomers rotate polarized light through opposite  angles, canceling each other out so that the racemic mixture has no opti�  cal activity. Racemization is the conversion of an optically active form of  a compound into a racemic mixture; reversing this process is called reso�  lution.</p><p>racer Any of several slender, swift snakes (subspecies of Coluber con�  strictor, family Colubridae) of North  and Central America and Asia.

Jacob was  forced to serve her father, Laban, for seven years to win her, but at the  end of that time he was tricked into marrying her sister, Leah. He was  then allowed to marry Rachel as well, in return for seven more years of  labour. At first childless, Rachel eventually gave birth to Joseph, and she  died giving birth to Benjamin.</p><p>Rachmaninoff yrak-'ma-no-.noA, Sergey (Vassilyevich) (b. April  1, 1873, Oneg, near Semyonovo, Russia�d. March 28, 1943, Beverly  Hills, Calif., U.S.) Russian-born U.S. composer and pianist. He studied  at the St. Petersburg and Moscow conservatories. After playing his first</p><p>concerto for his graduation as a piano student (1891), he stayed on to earn  a composition degree, writing his first opera, Aleko (1892). His first sym�  phony (1897) was such a disaster that he could not compose for three  years. Known for his titanic virtuosity as a pianist, he toured widely while  returning to composing prolifically. He moved to the U.S. after the 1917  revolution. His works, most of them in a lush late-Romantic style, include  three symphonies, four piano concertos, the tone poem From the Isle of  the Dead (1909), and Symphonic Dances (1940).</p><p>Racine \ra-'sen\, Jean (-Baptiste) (baptized Dec. 22, 1639, La Ferte-  Milon, France�d. April 21, 1699, Paris) French playwright. Orphaned at  an early age, he was educated in a Jansenist convent, and he chose drama  in defiance of his upbringing. His first play was produced by Moliere in  1664. Their friendship ended when Racine took his next play, Alexander  the Great (1665), to a competing theatre and seduced Moliere�s mistress  and leading actress, Therese du Parc. She starred in Racine�s successful  Andromaque (1667), which explored his theme of the tragic folly of pas�  sionate love. His only comedy, The Litigants (1668), was followed by his  great tragedies Britannicus (1669), Berenice (1670), and Bajazet (1672).  After writing his masterpiece, Phedre (1677), a tragedy drawn from Greek  mythology, he retired to become official historian to Louis XIV. His final  plays, Esther (1689) and Athalie (1691), were commissioned by the king�s  wife, Mme. de Maintenon.</p><p>racism Any action, practice, or belief that reflects the racial  worldview�the ideology that humans are divided into separate and exclu�  sive biological entities called �races,� that there is a causal link between  inherited physical traits and traits of personality, intellect, morality, and  other cultural behavioral features, and that some �races� are innately supe�  rior to others. Racism was at the heart of North American slavery and the  overseas colonization and empire-building activities of some western  Europeans, especially in the 18th century. The idea of RACE was invented  to magnify the differences between people of European origin in the U.S.  and those of African descent whose ancestors had been brought against  their will to function as slaves in the American South. By viewing Afri�  cans and their descendants as lesser human beings, the proponents of sla�  very attempted to justify and maintain this system of exploitation while  at the same time portraying the U.S. as a bastion and champion of human  freedom, with human rights, democratic institutions, unlimited opportu�  nities, and equality. The contradiction between slavery and the ideology  of human equality, accompanying a philosophy of human freedom and  dignity, seemed to demand the dehumanization of those enslaved. By the  19th century racism had matured and the idea spread around the world.  Racism differs from ethnocentrism in that it is linked to physical and  therefore immutable differences among people. Ethnic identity is  acquired, and ethnic features are learned forms of behaviour. Race, on the  other hand, is a form of identity that is perceived as innate and unalter�  able. In the last half of the 20th century several conflicts around the world  were interpreted in racial terms even though their origins were in the eth�  nic hostilities that have long characterized many human societies (e.g.,  Arabs and Jews, English and Irish). Racism reflects an acceptance of the  deepest forms and degrees of divisiveness and carries the implication that  differences among groups are so great that they cannot be transcended.  See also ethnic group; sociocultural evolution.</p><p>rack and pinion Mechanical device consisting of a bar of rectangu�  lar cross section (the rack), having teeth on one side that mesh with teeth  on a small gear (the pinion). If the pinion rotates about a fixed axis, the  rack will move in a straight path. Some automobile steering mechanisms  have rack-and-pinion drives that use this principle. If the rack is fixed and  the pinion is carried in bearings on a table guided on tracks parallel to the  rack, rotation of the pinion shaft will move the table parallel to the rack.  On machine tools, this principle is used to obtain rapid movements of  worktables.</p><p>racketeering See organized crime</p><p>rackets Game for two or four players with ball and racket on a four-  walled court. Rackets is played with a hard ball in a relatively large court  (approximately 9x18 m), unlike the related games of squash and rac-  quetball. As in these other games, the object of rackets is to bounce, or  rebound, the ball off the front and other walls in such a way as to defeat  an opponent�s attempt to reach and return it.

It can also measure precisely the distance (range) to an object and  the speed at which the object is moving toward or away from the observ�  ing unit. Radar (the name is derived from radio detecting and ranging)  originated in the experimental work of Heinrich Hertz in the late 1880s.  During World War II British and U.S. researchers developed a high-  powered microwave radar system for military use. Radar is used today in  identification and monitoring of artificial satellites in Earth orbit, as a  navigational aid for airplanes and marine vessels, for air traffic control  around major airports, for monitoring local weather systems, and for spot�  ting �speeders.�</p><p>radar astronomy See radio and radar astronomy</p><p>Radcliffe, Ann orig.

He taught at the universities of Cape Town, Sydney, Chicago,  and Oxford. In his version of functionalism, he viewed the component parts  of society (e.g., the kinship system, the legal system) as having an indis�  pensable function for one another, the continued existence of one com�  ponent being dependent on that of the other, and he developed a  systematic framework of concepts relating to the social structures of  small-scale societies.

As army chief of  staff, he attempted to modernize the Austrian army. As commander in  chief of the Austrian army in northern Italy (1831-57), he suppressed the  revolt in the Austrian-ruled provinces of Lombardy and Venetia in 1848.  He served as governor-general of these provinces (1849-57).

Once the dominant piston-engine  type, radials are now in only limited production; most new requirements  are met by remanufacturing existing stock.</p><p>radiant heating Heating system in which heat is transmitted by radia�  tion from a heated surface. Radiant heating systems usually employ either  electric-resistance wiring or hot-water heating pipes, which may embed�  ded in the floor, ceiling, or walls. Panel heating is a form of radiant heat�  ing characterized by very large surfaces (typically an entire ceiling or  floor) containing electrical conductors, hot-water pipes, or hot-air ducts.  With many such systems there is no visible heating equipment in the  room.</p><p>radiation Process by which energy is emitted from a source and propa�  gated through the surrounding medium, or the energy involved in this  process. Radiation consists of a flow of atomic or subatomic particles or  of waves. Familial' examples are light (a form of electromagnetic radia�  tion) and sound (a form of acoustic radiation). Both electromagnetic and  acoustic radiation can be described as waves with a range of frequencies  and intensities. Electromagnetic radiation is also often treated as discrete  packets of energy, called photons. All matter is constantly bombarded by  radiation from cosmic and terrestrial sources, and radioactive elements  emit several types of radiation (see radioactivity). See also Cherenkov radi�  ation, Hawking radiation, infrared radiation, synchrotron radiation, thermal</p><p>RADIATION, ULTRAVIOLET RADIATION.</p><p>radiation injury Tissue damage caused by exposure to ionizing radia�  tion. Structures with rapid cell turnover (e.g., skin, stomach or intestinal  lining, and bone marrow) are most susceptible. High-dose irradiation of  the last two causes radiation sickness. Nausea and vomiting subside in a  few hours. They are followed in intestinal cases by abdominal pain, fever,  and diarrhea leading to dehydration and a fatal shocklike state, and in  bone-marrow cases (two to three weeks later) by fever, weakness, hair  loss, infection, and hemorrhage. In severe cases, death occurs from infec�  tion and uncontrollable bleeding. Lower radiation doses can cause can�  cer (notably leukemia and breast cancer), sometimes years later. Radiation  exposure in early pregnancy can produce abnormalities in the embryo,  whose cells are multiplying rapidly.</p><p>radiation pressure Pressure on a surface resulting from electromag�  netic radiation that impinges on it. The pressure is a result of the momen�  tum carried by the radiation. When radiation is reflected rather than  absorbed, the radiation pressure is doubled. Radiation pressure can some�  times be great enough to produce a force that is useful.</p><p>radiation therapy or radiotherapy or therapeutic radiol�  ogy Use of radiation sources to treat or relieve diseases, usually cancer  (including leukemia). The ionizing radiation primarily used to destroy dis�  eased cells works best on fast-growing cancers. However, radiation can  also cause cancer (see radiation injury) and is no longer used for benign  conditions. Other complications include nausea, hair loss, weight loss, and  weakness. Radioactive substances may be implanted in tumours (see  nuclear medicine). External radiation involves 10-20 sessions over several  months, either after surgical removal of the growth or when surgery is  impossible; it can deliver higher doses to deep tumours than implantation.  Infrared radiation and ultraviolet radiation is applied with lamps to relieve  INFLAMMATION.</p><p>radical Term used in chemistry with one predominant and two subsid�  iary, looser meanings.

Zealous antislavery advocates in the Congress  pressed Pres. Abraham Lincoln to include emancipation as a war aim. They  later opposed his policy of lenient Reconstruction of the South under  presidential control and passed harsher measures in the Wade-Davis Bill.  After Lincoln�s death the Radicals supported Pres. Andrew Johnson but  soon demanded congressional control of Reconstruction. Johnson�s  attempt to break the Radicals� power led them to pass the Tenure of Office  Act; his challenge of the act led to his impeachment. Radical Republican  leaders included Henry Winter Davis (1817-65), Thaddeus Stevens, Charles  Sumner, and Benjamin Butler. Their influence waned as white control over  Southern governments gradually returned in the 1870s.</p><p>Radical-Socialist Party French political party. The oldest of France�s  political parties, it was founded in 1901 but originated in the 1870s in the  reformist wing of the French Republican Party, known as the Radicals,  led by Georges Clemenceau. Traditionally a centrist party, it was most  prominent in the Third Republic and Fourth Republic. In the 1920s and �30s  it joined coalition governments with the French Socialist Party. After 1945  it led other centrist groups to form politically important coalitions. By the  late 20th century, however, it was only a minor party. In 1998 it renamed  itself the Radical Party of the Left.</p><p>radio Electromagnetic radiation of lower frequency (hence longer wave�  length) than visible light or infrared radiation, and consisting of the range  of frequencies used for navigation signals, AM and FM broadcasting, tele�  vision transmissions, cell-phone communications, and various forms of  radar. For radio transmission, information is imparted to a carrier wave  by varying (modulating) its amplitude, frequency, or duration. The tech�  nology of radio arose from the work of Michael Faraday, James Clerk Max�  well, Heinrich Hertz, Gugueimo Marconi, and others, and improvement  followed the development of the vacuum tube, the electronic-tube oscilla�  tor, the tuned circuit, and other components. Later innovations have  included the replacement of tubes by transistors and of wires by printed  circuits. See also radio and radar astronomy.</p><p>radio and radar astronomy Study of celestial bodies by measur�  ing the energy they emit or reflect at radio wavelengths. It began in 1931  with Karl Jansky�s discovery of radio waves from an extraterrestrial  source. After 1945, huge dish antennas, improved receivers and data-  processing methods, and radio interferometers let astronomers study  fainter sources and obtain greater detail. Radio waves penetrate much of  the gas and dust in space, giving a much clearer picture of the centre and  structure of the Milky Way Galaxy than optical observation can. This has  allowed detailed studies of the interstellar medium in the Galaxy and the  discovery of previously unknown cosmic objects (e.g., pulsars, quasars).  In radar astronomy, radio signals are sent to near-Earth bodies or phe�  nomena (e.g., meteor trails, the Moon, asteroids, nearby planets) and the  reflections detected, providing precise measurement of the objects� dis�  tances and surface structure. Because radar waves can penetrate even  dense clouds, they have provided astronomers� only maps of the surface  of Venus. Radio and radar studies of the Moon revealed its sandlike sur�  face before landings were made. Radio observations have also contrib�  uted greatly to knowledge about the Sun. See also radio telescope.</p><p>radio broadcasting See broadcasting</p><p>radio telescope Combination of radio receiver and antenna, used for  observation in radio and radar astronomy. Radio telescopes vary widely,  but all have two basic components: a large radio antenna or an antenna  array and a radiometer or radio receiver. Because some astronomical radio  sources are extremely weak, radio telescopes are usually very large, and  only the most sensitive radio receivers are used. The first large fully steer�  able radio telescope was completed in 1957 at Jodrell Bank, Eng. The  world�s largest fully steerable radio telescope is the 360 x 330-ft (110 x  100-m) off-axis antenna operated by the National Radio Astronomy  Observatory in Green Bank, W.Va. The largest single radio telescope is  the 1,000-ft (305-m) fixed spherical reflector at the Arecibo Observatory  in Puerto Rico. The world�s most powerful radio telescope is the Very  Large Array in New Mexico, made up of 27 separate mobile parabolic  antennas that together provide the angular resolution of a single antenna  22 mi (35 km) in diameter.

The wavelengths of radio waves range  from thousands of metres to around 30 cm. These correspond to frequen�  cies as low as 3 Hz and as high as 1 gigahertz (10 9 Hz). Radio-wave com�  munications signals travel through the air in a straight line, reflect off of  clouds or layers of the ionosphere, or are relayed by satellites in space.  They are used in standard broadcast radio and television, short-wave  radio, navigation and air-traffic control, cellular telephony, and even  remote-controlled toys.

The natural series are the thorium series, the uranium series,  and the actinium series. These are headed by naturally occurring species  of unstable nuclei that have half-lives comparable to the age of the earth.  The fourth set, the neptunium series, is headed by neptunium-237, which  has a half-life of 2 million years. Its members do not occur naturally but  are artificially produced by nuclear reactions and have short half-lives.</p><p>radioactivity Property exhibited by certain types of matter of emitting  radiation spontaneously. The phenomenon was first reported in 1896 by  Henri Becquerel for a uranium salt, and it was soon found that all uranium  compounds are radioactive due to the uranium�s radioactivity. In 1898  Marie Curie and her husband discovered two other naturally occurring,  strongly radioactive elements, radium and polonium. The radiation is emit�  ted by unstable atomic nuclei (see nucleus) as they attempt to become more  stable. The main processes of radioactivity are alpha decay, beta decay, and  gamma decay. In 1934 it was discovered that radioactivity could be induced  in ordinary matter by artificial transmutation.</p><p>radiocarbon dating See carbon- 14 dating</p><p>radiology Branch of medicine that uses radiation for diagnosis (diagnos�  tic imaging) and treatment (radiation therapy) of disease.

Sept. 24, 1802, St. Petersburg) Rus�  sian political writer. Although from  the nobility, he pursued a career as a  civil servant, in which he met people  from all social classes. Influenced by  such writers as Jean-Jacques Rous�  seau, he wrote A Journey from St.  Petersburg to Moscow (1790), in  which he described examples of  social injustice, hoping that his criti�  cism of serfdom, autocracy, and cen�  sorship would enlighten Catherine II.  Instead, he was arrested and exiled  to Siberia. He was pardoned by Alex�  ander I in 1801 but committed sui�  cide a year later. He inspired later  revolutionaries, including those who  instigated the Decembrist revolt.</p><p>radium Chemical element, heaviest  alkaline earth metal, chemical symbol  Ra, atomic number 88. It was dis�  covered by Marie Curie and her hus�  band, Pierre Curie, in 1898 and  isolated by 1910. All its isotopes are  radioactive (see radioactivity).  Radium does not occur free in nature  but occurs in natural ores such as  pitchblende as a disintegration prod�  uct of radioactive decay of heavier  elements, including uranium. Chemi�  cally it is highly reactive and has  valence 2 in all of its compounds. Its  use in medicine (see radiation  therapy; radiology; nuclear medicine)  has declined because of its cost, and  its use in consumer goods (to illumi�  nate watch and clock hands and  numbers, as well as instrument dials)  was halted because it can cause  radiation injury. It is still used for  some radiography and as a source of  NEUTRONS.</p><p>radon \'ra-,dan\ Chemical element,  chemical symbol Rn, atomic number  86. The heaviest noble gas, it is  colourless, odourless, tasteless,  radioactive (see radioactivity), and  almost completely unreactive (form�  ing compounds only with fluorine).  It is rare in nature because all its iso�  topes are short-lived and because  radium, its source, is scarce.

They are primarily used in various  types of communications signals. Also  of importance is the detection of natural  radio sources in radio and radar  astronomy. A few applications are  shown at their approximate positions in  the spectrum (on a logarithmic scale).  Microwaves are a subset of the radio  spectrum, ranging from about 1 to  1000 mm in wavelength, or a fre�  quency between about 1 and 100  GHz. The microwave region is used  especially in various forms of radar, in  communications with spacecraft and  satellites (as in the Global Positioning  System), and in microwave ovens.  Amateur communications, such as CB  (citizens' band) and short-wave radio,  occur around 10 MHz. Marine naviga�  tion and communications systems oper�  ate especially below 1 MHz.

Though apprenticed early to  a goldsmith, he lacked formal training as a painter. He worked principally  as a miniaturist and evolved a distinctive style of oil portraiture, painting  directly on the canvas without preliminary drawings. His portraits are  characterized by a vigorous handling of paint and vivid and experimen�  tal lighting effects, usually from behind the sitters� heads. He was elected  president of the Edinburgh Society of Artists (1812) and Royal Academi�  cian (1815), knighted in 1822, and appointed His Majesty�s Limner for  Scotland (1822).</p><p>Raeder Vra-dor\, Erich (b.

As  naval commander in chief from 1928, he urged the construction of sub�  marines (forbidden by the Treaty of Versailles) and fast cruisers. Appointed  grand admiral in 1939, he supervised the invasion of Denmark and Nor�  way in 1940. Differences with Adolf Hitler led to his dismissal from  supreme command in 1943. He was sentenced to life in prison at the  Nurnberg trials, but he was released because of ill health in 1955.</p><p>Raetia or Rhaetia Vre-she-o\ Ancient Roman province south of the  Danube River. It comprised parts of present-day Austria, Switzerland, and  Germany. Its native inhabitants were probably of mixed Illyrian and Celtic  descent. Conquered by Rome in 15 bc, it became an important part of the  empire for its position on the highways between Italy and the Danube and  between Gaul and the Balkans. Because it was a frontier province, its  boundaries shifted when German tribes encroached; in the 1st century ad,  the northern boundary extended to the Neckar River, but in the 3rd cen�  tury the western and northern boundaries were pulled back. By 450, Rome  controlled only the alpine regions.</p><p>RAF See Royal Air Force</p><p>Raffles, Sir (Thomas) Stamford (b. July 6, 1781, at sea off Port  Morant, Jam.�d. July 5, 1826, London, Eng.) Administrator in the Brit�  ish East India Company and founder of Singapore. He joined the British  East India Company at age 14, and his hard work won him an appoint�  ment as assistant secretary to the government of Penang (in present-day  Malaysia). There he undertook an intensive study of the Malayan peoples,  and his knowledge allowed him to play a key role in 1811, when the Brit�  ish defeated Dutch-French forces in Java. He subsequently became lieu�  tenant governor there and inaugurated a mass of reforms aimed at  transforming the Dutch colonial system and improving the condition of  the native population. He was recalled by the company, which deemed  his reforms too costly; though he was popular in London (he was knighted  in 1816), his authority when he resumed his service in Southeast Asia  was severely restricted. Undeterred, he founded the port city of Singapore  in 1819 in order to to ensure British access to the China seas; in 1824 the  Dutch relinquished all claims to Singapore. Raffles is credited with cre�  ating Britain�s Far Eastern empire.</p><p>raga In the classical music of India and Pakistan, a melodic framework  for improvisation based on a given set of notes (usually five to seven) and  characteristic rhythmic patterns. A raga can be regarded as a vocabulary  of melodic figures that tend, as a group, to emphasize certain tones of a  scale, giving the raga a specific emotional character and implying the kind  of music to be improvised. The emphasis on certain pitches effectively  divides the scale into primary and secondary tones; the secondary tones  serve to ornament the primary tones, thus reinforcing the emphasis. Each  scale can have several different ragas, depending on which tones of the  scale are made primary. Two additional factors contribute to the artistic  potential of the raga: the division of tones between primary and second�  ary is not always hard and fast; moreover, a tertiary level (ornaments of  the ornaments) is often made available to the performer. The concept of  raga, introduced sometime before the 9th century, became influential  throughout South and East Asia.

Raglan became the scapegoat for the campaign�s lack of progress  and the inadequate supplies to the troops in the winter of 1854-55. His  name was applied to the raglan sleeve, probably designed to adapt his  coat to the arm he had amputated after the Battle of Waterloo.</p><p>Ragnarok \'rag-n9-,roek, 'rag-no-.rakN In Scandinavian mythology, the  end of the divine and human worlds. As described in the 10th-century  Icelandic poem Voluspa and other sources, Ragnarok will be preceded by  cruel winters and moral chaos. Giants and demons will attack the gods,  who will face death like heroes. The sun will be darkened, the stars will  vanish, and the earth will sink into the sea. Afterward the earth will rise  again, the innocent Balder will return from the dead, and the hosts of the  just will live in a hall roofed with gold. The title of Richard Wagner�s  opera Gotterdammerung (The Twilight of the Gods ) is a German equiva�  lent of Ragnarok.</p><p>ragtime U.S. popular music of the late 19th and early 20th centuries  distinguished by its heavily syncopated rhythm. Ragtime found its char�  acteristic expression in formally structured piano compositions, the  accented left-hand beat opposed in the right hand by a fast, bouncing  melody that gave the music its powerful forward impetus. (The term  probably derives from �ragged time,� a description of syncopation.) Rag�  time compositions typically featured three or four discrete 16-bar strains  performed at a moderate tempo. The most celebrated ragtime composer  was Scott Joplin. The rhythm and structure of ragtime were important  influences on the development of jazz.</p><p>ragweed Any of about 15 species of weedy plants (see weed) that make  up the genus Ambrosia in the composite family, most of which are native  to North America. They have rough hairy stems, mostly lobed or divided  leaves, and inconspicuous greenish flowers borne in small heads. Com�  mon ragweed (A. artemisiifolia ) is found across North America. Pollen  shed by ragweeds in great abundance in late summer is the principal cause  of hay fever in eastern and middle North America. Since ragweeds are  annuals, mowing before pollination season eradicates them.</p><p>rail Any of about 100 species (family Rallidae) of slender marsh birds  found almost worldwide. Rails have  short rounded wings, a short tail,  large feet, and long toes. Their loud  call, especially at night, reveals their  presence in dense vegetation. They  are mostly dull grays and browns,  often with barred patterns. Species  vary from 4 to 18 in. (11-45 cm)  long. Short-billed species are often  called crakes. The king ( Rallus ele-  gans), clapper (R. longirostris ), and  Virginia ( R. limicola) rails and the  sora, or Carolina rail ( Porzana Caro�  lina ), have been hunted in the U.S.;  several of the rails are now endan�  gered, and some species have been  exterminated.</p><p>railroad Mode of land transportation in which flange-wheeled vehicles  move over two parallel steel rails or tracks, drawn by a locomotive or pro�  pelled by self-contained motors. The earliest railroads were built in Euro�  pean mines in the 16th century, using cars pulled on tracks by men or  horses. With the advent of the steam locomotive and construction of the  first railway in 1825, the modem railroad developed quickly. The first U.S.  railroad, the Baltimore and Ohio, began operation in 1827. Specialized rail�  road cars were built to transport freight and passengers, including the sleep�  ing cars developed by George Pullman in 1859. In the 19th century the  railroad had an important influence on every country�s economic and social  development. In the U.S. the transcontinental railroad, completed in 1869,  began an era of railroad expansion and consolidation that involved such  financial empire builders as Cornelius Vanderbilt, Jay Gould, Edward H. Har-  riman, James J. Hill, and Leland Stanford. The railroad�s importance in the  U.S. began to diminish from the early 20th century, but in Europe, Asia, and  Africa it continues to provide vital transportation links within and between  countries.

It was founded by the</p><p>U.S. government as the American Railway Express Co. in 1918, when the  nation�s major express carriers�Adams &amp; Co., American Express Co.,  Wells, Fargo &amp; Co., and Southern Express Co.�were merged into a pub�  lic corporation. An association of railroads bought out the business in  1929 and began to operate it as the Railway Express Agency. Its name  was changed to REA Express in 1970. Poor management, strikes, and  competition led to heavy losses, and REA filed for bankruptcy in 1975.</p><p>Raimondi \ri-'man-de, ri-'mon-deN, Marcantonio (b. c. 1480, near  Bologna�d. c. 1534, Bologna) Italian engraver. He trained in Bologna  under Francesco Francia, but his energetic lines and use of cross-hatching  in modeling were influenced by Albrecht Durer. After he moved to Rome  c. 1510, he specialized in reproducing works by other artists, particularly  Raphael. He retained Raphael�s idealized figures but provided his own  background and landscapes. His engravings sold in large numbers and  did much to spread High Renaissance style throughout Europe during his  lifetime.</p><p>rain Precipitation of liquid water drops with diameters greater than 0.02  in. (0.5 mm). When the drops are smaller, the precipitation is usually  called drizzle. Raindrops may form by the coalescence of colliding small  water droplets or from the melting of snowflakes and other ice particles  as they fall into warm air near the ground. Hawaii�s Mount Waialeale,  with a 20-year annual average of 460 in. (11,700 mm), is the Earth�s wet�  test known point; the driest areas are in parts of deserts where no appre�  ciable rain has ever been observed. Less than 10 in. (250 mm) and more  than 60 in. (1,500 mm) per year represent approximate extremes of rain�  fall for all the continents.</p><p>rain dance Ceremonial dance performed to bring rain needed to water  crops. Rain dances have been customary in many cultures, from the  ancient Egyptians to the civilization of the Mayas and the people of the  20th-century Balkans. Rain dances often include dancing in a circle, the  participation of young girls, decoration with green vegetation, nudity, the  pouring of water, and whirling, meant to act as a wind charm. They may  also include phallic and fertility rites.</p><p>rainbow Series of concentric, coloured arcs that may be seen when light  from a distant source�usually the Sun�falls on a collection of water  drops such as in rain, spray, or fog. The coloured rays of the rainbow are  caused by the refraction and internal reflection of light rays that enter the  drop, each colour being bent through a slightly different angle. Hence, the  combined colours are separated upon emerging from the drop. The most  brilliant and most common rainbow is the so-called primary bow, which  results from light that emerges from the drop after one internal reflection.  The colours of the arc (from outside to inside) are red, orange, yellow,  green, blue, indigo, and violet. Occasionally a less-intense secondary bow  may be observed; it has its colour sequence reversed.</p><p>Rainbow Bridge National Monument Natural area, southern  Utah, U.S. Located on the Navajo Indian Reservation near the Utah-  Arizona border, the monument was established in 1910 and occupies 160  acres (65 hectares).

Despite  increased awareness of the rainforests� importance during the late 20th  century, they continue to be cleared. Rainforests grow mainly in South  and Central America, West and Central Africa, Indonesia, parts of South�  east Asia, and tropical Australia, where the climate is relatively humid  with no marked seasonal variation. Depending on the amount of annual  rainfall, the trees may be evergreen or mainly deciduous. The former  require more water. Temperatures are high, usually about 86 �F (30 �C)  during the day and 68 �F (20 �C) at night. Soil conditions vary with loca�  tion and climate, though most rainforest soils tend to be permanently  moist and not very fertile, because the hot, humid weather causes organic  matter to decompose rapidly and to be absorbed quickly by tree roots and  fungi. Rainforests have several layers. The highest continuous layer,  called the canopy, extends across the treetops at a height of 100-165 ft  (30-50 m). Most animals live among the leaves and branches. Below the  canopy is a thick understory filled with small trees, lianas, and epiphytes.  The space directly above the ground can be occupied by tree branches,  twigs, and foliage, but, contrary to popular belief, the rainforest floor is  not impassable. Rather, it is bare except for a thin layer of humus and fallen  leaves. Animals inhabiting this layer (e.g., gorillas, elephants, jaguars, and  bears) are adapted to walking or climbing for only short distances. Bur�  rowing animals, such as armadillos and caecilians, are found in the soil,  as are microorganisms that help decompose and recycle the organic litter  accumulated by other plants and animals from all layers. The climate of  the ground layer is unusually stable because the upper stories of tree  canopies and the lower branches filter out sunlight, retain heat, and reduce  wind speeds, keeping the temperature fairly even.</p><p>Rainier \ren-'ya,\ English \ra-'nir\ III orig.

Two types of memory are  possible with random-access circuits, static RAM (SRAM) and dynamic  RAM (DRAM). A single memory chip is made up of several million  memory cells. In a SRAM chip, each memory cell stores a binary digit  (1 or 0) for as long as power is supplied. In a DRAM chip, the charge on  individual memory cells must be refreshed periodically in order to retain  data. Because it has fewer components, DRAM requires less chip area  than SRAM; hence a DRAM chip can hold more memory, though its  access time is slower.</p><p>Rama Major Hindu deity. The name became associated with Ramacan-  dra, the seventh incarnation of Vishnu, whose story is told in the Rama-  yana. Conceived as a model of reason, virtue, and right action, Rama was  one of the chief objects of the bhakti cults. He is often depicted as a stand�  ing figure, holding an arrow in his right hand and a bow in his left. In  temples his image is attended by the figures of his wife, SlTA, his half  brother, Laksmana, and the monkey general, Hanuman.</p><p>Rama IV See Mongkut  Rama V See Chulalongkorn  Rama VI See Vajiravudh  Rama IX See Bhumibol Adulyadej</p><p>Ramadan \ra-ma-'dan\ In Islam, a holy month of fasting, the ninth  month of the Muslim year, commemorating the revelation of the Qur�an  to Muhammad. As an act of atonement, Muslims are required to fast and  abstain from sexual activity during the daylight hours of Ramadan. Deter�  mined according to the lunar calendar, Ramadan can fall in any season  of the year. The Ramadan fast is considered one of the Five Pillars of  Islam, and the end of the fast is celebrated as one of the important reli�  gious holidays of Islam.</p><p>Ramakrishna (Paramahamsa) orig. Gadadhar Chatto-  padhyaya (b. Feb. 18, 1836, Hooghly, Bengal state, India�d. Aug.  16, 1886, Calcutta) Indian mystic. Born into a poor Brahman family, he  worked as a priest in a temple of Kali in Calcutta (now Kolkata), where</p><p>he had a vision and commenced spiritual practices in a number of differ�  ent religious traditions. He denounced sexual desire and money as the twin  evils that put spiritual enlightenment beyond reach, rejected the caste sys�  tem, and held that all religions are in essence the same and that all are  true. His teachings were spread by his disciples, notably Vivekananda. A  religious order bearing his name, with headquarters in Kolkata, sends  missionaries throughout the world.</p><p>Raman Vra-msnV Sir Chandrasekhara Venkata (b. Nov. 7,  1888, Trichinopoly, India�d.

He received a Nobel Prize  in 1930 for discovering that when light passes through a transparent mate�  rial, some of the light that emerges at a right angle to the original beam  is of other frequencies (Raman frequencies) characteristic of the material.  He contributed to the building up of nearly every Indian research insti�  tution in his time, founded a scholarly physics journal and an academy  of sciences, and trained hundreds of students.</p><p>Ramana Maharshi Vro-ma-no-ms-'hor-sheN orig. Venkatara-  man Aiyer (b. Dec. 30, 1879, Madurai, Madras state, India�d. April  14, 1950, Tiruvannamalai) Hindu spiritual leader. Born into a Brahman  family, he left his village at age 17 to become a hermit on Mount  Arunachala, where Shiva was said to have entered the world at creation.  One of India�s youngest gurus, he held that evil and death were an illu�  sion, which could be dissipated through his technique of vicara (self-  pondering inquiry), and that to achieve liberation from rebirth it was  necessary to practice bhakti (devotional surrender) either to Shiva or to  Ramana Maharshi himself.</p><p>Ramananda V.ra-mo-'non-dsV (b. c. 1400�d. c. 1470) Indian spiritual  leader. He lived as an ascetic before settling in Varanasi (Benares) to study  Vedic texts and the philosophy of Ramanuja. He was fifth in succession  in the lineage of Ramanuja, but his determination to ignore caste distinc�  tions led to a break with the philosopher�s other followers. With 12 dis�  ciples he founded his own sect, the Ramanandis, who practiced devotion  to Rama. His teachings were similar to Ramanuja�s, but he dropped the  ban on intercaste dining and the strict rule that all teaching and all texts  must be in Sanskrit, himself teaching in the vernacular Hindi in order to  reach the masses who did not know Sanskrit.</p><p>Ramanuja \ra-'ma-nu-j3\ (b. c. 1017, Shriperumbudur, India�d. 1137,  Shrirangam) Indian theologian and  philosopher, the most influential  thinker of devotional Hinduism. After  a long pilgrimage through India, he  founded centres to spread devotion  to Vishnu and Lakshmi. He provided  an intellectual basis for the practice  of bhakti in major commentaries on  the Vedas, the Brahma-sutras, and  the Bhagavadgita. He was a major  figure in the school of Visistadvaita,  which emphasized the need for the  soul to be united with a personal god.</p><p>His chief philosophical contributions  follow from his conviction that the  phenomenal world is real and pro�  vides real knowledge and that the  exigencies of daily life are not con�  trary to the life of the spirit.</p><p>Ramanujan \ra-'man-u-j3 n \,</p><p>Srinivasa (Aaiyangar) (b.

In 1913 he began a correspondence with  Godfrey H. Hardy (1877-1947) that took him to England, where he made  advances, especially in the theory of numbers, the partition of numbers,  and the theory of continued fractions. He published papers in English and  European journals, and in 1918 he became the first Indian elected to the  Royal Society of London.

He died by drowning in the Ganges.</p><p>Ramayana Vra-'ma-yo-noV Indian epic poem, composed in Sanskrit c.  300 bce. With the Mahabharata, it is one of the two great epic poems of  India. Consisting of 24,000 couplets in seven books, it describes the royal  birth of Rama and the loss of his throne. Banished to the forest with his wife,  SlTA, and his half brother, Laksmana, he spends 14 years in exile. When a  demon king carries off Sita, Rama enters into an alliance with Sugriva, king  of the monkeys, and Hanuman, the monkey general, who help him rescue  her. Rama regains his kingdom, but Sita is banished when her chastity is  questioned, and she is swallowed by the earth after proving her innocence.</p><p>Rambert \ram-'ber\, Dame Marie orig. Cyvia Rambam (b. Feb.  20, 1888, Warsaw, Pol., Russian Empire�d. June 12, 1982, London,  Eng.) Polish-born English ballet producer and director. She studied with  the musician Emile Jaques-Dalcroze and taught his technique, eurythmics,  to the Paris-based Ballets Russes, influencing Vaslav Nijinsky�s avant-garde  choreography. At the outbreak of World War I, she moved to London,  where she studied ballet with Enrico Cecchetti (1850-1928); in 1920 she  founded a ballet school that used his methods. In 1930 she helped found  the Camargo Society and established the Ballet Club (later Ballet Ram�  bert). As director of Ballet Rambert, she favoured experimentation,  encouraging young choreographers such as Frederick Ashton and support�  ing new dancers and stage designers. Her troupe, renamed the Rambert  Dance Company in 1987, has continued to perform.</p><p>Rameau \ra-'mo\, Jean-Philippe (baptized Sept. 25, 1683, Dijon,  France�d. Sept. 12,1764, Paris) French composer and music theorist. Son  of an organist, he held organist posts until he was 49. His Treatise on Har�  mony (1722) established him as a major music theorist. In it he asserted that  harmony is the basis of music, and that chords, which had been understood  principally as collections of intervals above a bass, should instead be seen  as representing inversions of more fundamental harmonic entities. From  1733 he wrote a series of highly successful operas, including Hippolyte et  Aricie (1733) and The Gallant Indies (1735), assuring his place as the most  important French opera composer since Jean-Baptiste Lully. In the querelles  des bouffons (�war of the buffoons,� 1752-53), a famous artistic contro�  versy about the relative merits of French and Italian opera, Rameau�s music  exemplified the French style. He also won renown for his many keyboard  pieces, mostly composed for harpsichord.</p><p>ramjet Air-breathing jet engine that operates with no major moving parts.  It relies on the craft�s forward motion to draw in air and on a specially  shaped intake passage to compress the air for combustion. After fuel  sprayed into the engine has been ignited, combustion is self-sustaining.  As in other jet engines, forward thrust is obtained as a reaction to the  rearward rush of hot exhaust gases. Ramjets work best at speeds of Mach  2 (twice the speed of sound) and higher.

He united a region that shared a common reli�  gion (Theravada Buddhism). Under him, the arts developed distinctively  Tai expressions, and accomplished bronze sculptures were created. He is  also credited with inventing the Thai alphabet, a modification of Khmer  script. He was remembered only in legend until 1834 when King Mong-  kut of Siam (then a Buddhist monk) rediscovered an inscription  Ramkhamhaeng had made in 1292. As a result, he came to be regarded  as a national hero, a just and liberal ruler who imparted a sense of cul�  tural unity to the region.</p><p>rammed earth or pise de terre Vpe-.za-do-'terX Building material  made by compacting and drying a stiff mixture of clay, sand or other  aggregate, and water. It has been used by many civilizations. The most  durable of the earth-building forms, it is formed into building blocks (see  adobe) or rammed within removable wooden forms in layers or lifts to  construct walls. China�s Erligang (c. 1600 bc) is an example of a rammed-  earth fortification; it covers an area of 1.2 sq mi (3.2 sq km) and may  have taken 10,000 people more than 12 years to build.</p><p>Rampal \ram-'pal\, Jean-Pierre (-Louis) (b.

In the 1950s he founded his</p><p>own chamber groups, while also playing in the pit at the Paris Opera  (1956-62). Works were written for him by Francis Poulenc and others.  His sweetness of tone and virtuosity in a largely Baroque repertoire, as  evidenced on many admired recordings, made him the first flutist to attain  international stardom.</p><p>Ramses \Tam-,sez\ II known as Ramses the Great (fl. 13th century  bc) King of ancient Egypt, 1279-13  bc. His family came to power some  decades after the reign of Akhenaton.</p><p>Ramses set about restoring Egypt�s  power by quelling rebellions in  southern Syria and fighting the Hit-  tites inconclusively at the Battle of  Kadesh. He captured towns in Gali�  lee and Amor, but, unable to defeat  the Hittites, he assented to a peace  treaty in 1258 bc. He married one  and perhaps two of the Hittite king�s  daughters, and the later part of his  reign was free from war. Its prosper�  ity may be measured by the amount  of construction he undertook. Early  on he built himself a residence city  in the Nile delta as a base for mili�  tary campaigns and resumed con�  struction of the temple of Osiris,  begun by his father. He added to the  temple at Karnak and completed a  funerary temple for his father at  Luxor. In Nubia he built six temples,  most famously those at Abu Simbel.</p><p>Ramses III (d. 1156 bc) King of ancient Egypt, 1187-56 bc.

Used in studying chance events, it is defined so as to account  for all possible outcomes of the event. When these are finite (e.g., the  number of heads in a three-coin toss), the random variable is called dis�  crete and the probabilities of the outcomes sum to 1. If the possible out�  comes are infinite (e.g., the life expectancy of a light bulb), the random  variable is called continuous and corresponds to a density function whose  integral over the entire range of outcomes equals 1 . Probabilities for spe�  cific outcomes are determined by summing probabilities (in the discrete  case) or by integrating the density function over an interval correspond�  ing to that outcome (in the continuous case).</p><p>range finder Instrument used to measure the distance from the instru�  ment to a selected point or object.

His literary studies include The New Criticism  (1941), which gave its name to an important critical movement (see New  Criticism), and he became recognized as a leading theorist of the post-  World War I Southern literary renaissance. His Selected Poems (1945; rev.  ed., 1969) won the National Book Award.</p><p>rap Musical style in which rhythmic and/or rhyming speech is chanted  (�rapped�) to musical accompaniment. This backing music, which can  include digital sampling (music and sounds extracted from other record�  ings), is also called hip-hop, the name used to refer to a broader cultural  movement that includes rap, deejaying (turntable manipulation), graffiti  painting, and breakdancing. Rap, which originated in African American  communities in New York City, came to national prominence with the  Sugar Hill Gang�s �Rapper�s Delight� (1979). Rap�s early stars included  Grandmaster Flash and the Furious Five, Run-D.M.C., LL Cool J, Public  Enemy (who espoused a radical political message), and the Beastie Boys.  The late 1980s saw the advent of �gangsta rap,� with lyrics that were often</p><p>misogynistic or that glamorized violence and drug dealing. More recent  stars have included Sean �Puffy� Combs, Jay-Z, OutKast, and Eminem.</p><p>Rapa Nui See Easter Island</p><p>Rapallo \ra-'pa-l6. Treaty of (April 16, 1922) Treaty between Ger�  many and the Soviet Union, signed at Rapallo, Italy. Negotiated by Ger�  many�s Walther Rathenau and the Soviet Union�s Georgy V. Chicherin, it  reestablished normal relations between the two nations. The nations  agreed to cancel all financial claims against each other, and the treaty  strengthened their economic and military ties. As the first agreement con�  cluded by Germany as an independent agent since World War I, it angered  the Western Allies.</p><p>rape Annual plant {Brassica napus) of the mustard family, native to  Europe. This 1-ft-tall (30-cm) plant  has a long, thin taproot; smooth,  bluish-green, deeply scalloped  leaves; and clusters of yellow flow�  ers. Each round, elongated seedpod  has a short beak and contains many  seeds. The seeds yield an oil (rape-  seed oil, or canola) that is the lowest  in saturated fat of any edible oil, mak�  ing it popular for use in cooking. It is  also used as an ingredient in soap and  margarine and as a lamp fuel.</p><p>rape Unlawful sexual activity, usu�  ally sexual intercourse, carried out  forcibly or under threat of injury and  against the will of the victim.</p><p>Though traditionally limited to  attacks on women by men, the defi�  nition of rape has been broadened to  cover same-sex attacks and attacks  against those who, because of men�  tal illness, intoxication, or other reasons, are incapable of valid consent.  Statutory rape, or intercourse with a person younger than a certain age  (generally from 12 to 18 years), has long been a serious crime in most  jurisdictions. Rape is widely considered an expression of anger or aggres�  sion and a pathological assertion of power by the rapist. The psychologi�  cal responses of victims vary but usually include feelings of shame,  humiliation, confusion, fear, and rage. Many rape victims fail to report  the crime, deterred by the prospect of a distressing cross-examination in  court and the difficulty of proving a crime for which there usually are no  witnesses. In the late 20th century there was a notable increase in the use  of rape as a weapon of war, and in the 1990s the tribunal investigating  crimes stemming from genocide in Rwanda ruled that rape and sexual  violence constituted a form of genocide.

April 6, 1520, Rome, Papal States) Italian  painter and architect. As a member of Perugino�s workshop, he established  his mastery by 17 and began receiving important commissions. In 1504 he  moved to Florence, where he executed many of his famous Madonnas; his  unity of composition and suppression of inessentials is evident in The  Madonna of the Goldfinch (c. 1506). Though influenced by Leonardo da  Vinci�s chiaroscuro and sfumato, his figure types were his own creation,  with round, gentle faces that reveal human sentiments raised to a sublime  serenity. In 1508 he was summoned to Rome to decorate a suite of papal  chambers in the Vatican. The frescoes in the Stanza della Segnatura are  probably his greatest work; the most famous. The School of Athens (1510�  11), is a complex and magnificently ordered allegory of secular knowledge  showing Greek philosophers in an architectural setting. The Madonnas he  painted in Rome show him turning away from his earlier work�s serenity to  emphasize movement and grandeur, partly under Michelangelo�s High  Renaissance influence. The Sistine Madonna (1513) shows the richness of  colour and new boldness of compositional invention typical of his Roman  period. He became the most important portraitist in Rome, designed 10  large tapestries to hang in the Sistine Chapel, designed a church and a chapel,  assumed the direction of work on St. Peter's Basilica at the death of Donato  Bramante, and took charge of virtually all the papacy�s projects in archi�  tecture, painting, and the preservation of antiquities. When he died on his  37th birthday, his last masterpiece, the Transfiguration altarpiece, was  placed at the head of his bier.</p><p>Jeannette Rankin, 1918.</p><p>LIBRARY OF CONGRESS, WASHINGTON, D.C.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Raphael &#x25BA; Rastenburg Assassination Plot I 1591</p><p>Raphael In the Bible and the Qur�an, one of the archangels.

After the American Civil War he returned to Alabama, where he  became a successful cotton planter and a delegate to the state�s first  Republican convention. Serving in the U.S. House of Representatives  (1873-75) during Reconstruction, he worked for passage of the Civil  Rights Act of 1875. He was later collector of internal revenue in Ala�  bama�s second district, and he remained active as a labour organizer and  publisher of the Montgomery Sentinel.</p><p>raptor \'rap-tor \ In general, any bird of prey, including owls.

The metals never occur free, and the pure oxides never occur  in minerals. These metals are similar chemically because their atomic  structures are generally similar; all form compounds in which they have  valence 3, including stable oxides, carbides, and borides.</p><p>Ra�s NasranT See Cape NasranT</p><p>Rashi \'ra-she\ in full Rabbi Shlomo Yitzhaqi (b. 1040, Troyes,  Champagne�d.

His  influential writings on the Bible examined the literal meaning of the text  and used allegory, parable, and symbolism to analyze its nonliteral mean�  ing. His landmark commentary on the Talmud is a classic introduction to  biblical and postbiblical Judaism.</p><p>Rashid Rida Xra-'shed-re-'daV Muhammad (b. 1865, Syria�d.  1935, Syria) Syrian Islamic scholar. As founder (1898) and publisher of  the newspaper Al-Manar, he helped Muslims formulate an intellectual  response to the problem of reconciling their religious heritage with the  modern world. He was concerned with the backwardness of the Muslim  countries, which he proposed to remedy by reviving the original principles  of Islam. He advocated that rulers consult with religious leaders in for�  mulating government policies. He also urged Arabs and Muslims to emu�  late the scientific and technological progress of the West.</p><p>Rashidun \,ra-shi- , dun\ Arabic "Rightly Guided" First four caliphs  of the Islamic community: AbG Bakr, 'Umar ibn al-Khattab, 'Uthman ibn  'Affan, and �All As Islam�s first rulers after Muhammad, they assumed all  his duties except prophecy: they led the congregation in prayer, delivered  the Friday sermons, and commanded the army.

Its importance as the  main city of the Gllan region dates from Russia�s expansion southward  in the 17th century. In the 20th century, it was severely damaged by Rus�  sian occupation during both world wars. Surrounded by rice fields and  areas of half-cleared forests, it is a market and processing centre for rice,  tea, peanuts, and silk.</p><p>Rask Vrask\, Rasmus (Kristian) (b.

His observation that sound shifts between  corresponding words in Germanic and other Indo-European languages fol�  lowed predictable patterns was the basis of a fundamental law of linguis�  tics later enunciated by Jacob Grimm (Grimm�s law). Rask also carried out  extensive research on Old Norse, publishing his Investigation of the Ori�  gin of the Old Norse or Icelandic Language in 1818. By the end of his  life he had mastered 25 languages and dialects.</p><p>Raskob Vras-kobV, John Jakob (b. March 19, 1879, Lockport, N.Y.,  U.S.�d. Oct. 15, 1950, Centreville, Md.) U.S. financier. He went to work  for E.I. du Pont de Nemours &amp; Co. in 1902 and played a major role in  Du Pont�s expansion in the early 20th century. He joined the board of  General Motors in 1915; as chairman of its finance committee from 1918,  he greatly increased sales and earnings, establishing the General Motors  Acceptance Corp. (GMAC) to allow dealers to finance their inventory and  offer credit and long-term financing to their customers. He left in 1928  to head the Democratic National Committee and run Alfred E. Smith�s  unsuccessful presidential campaign; later he and Smith helped direct the  construction of the Empire State Building.</p><p>raspberry Any of many species of fruit-bearing bushes of the genus  Rubus in the rose family. When  picked, the juicy red, purple, or black  berry separates from a core, whereas  in the related blackberry the core is  part of the fruit. Both so-called ber�  ries are actually aggregate fruits. Red  raspberries are propagated by suck�  ers (see suckering) from the roots of  the parent plant or from root cuttings.</p><p>Black and purple varieties have  arched canes and are propagated by  layering of the shoot tips. Raspberries  contain iron and vitamin C. They are  eaten fresh and are also very popular  in jams, as a pastry filling, and as a flavouring for liqueurs.</p><p>Rasputin Xra-'spyu-UnX, Grigory (Yefimovich) orig. Grigory  (Yefimovich) Novykh (b. 1872?, Pokrovskoye, near Tyumen, Sibe�  ria, Russian Empire�d. Dec. 30, 1916, Petrograd) Russian mystic influ�  ential at the court of Tsar Nicholas II and Alexandra. An illiterate peasant,  he earned the name rasputin (�debauched one�) for his early licentious  behaviour. After undergoing a religious experience, he gained a reputa�  tion among the peasants as a holy man, able to heal the sick. He became  known to Nicholas and the susceptible Alexandra, and he proved capable  of stopping the bleeding of their hemophiliac son, probably by means of  hypnotism. He became a favourite at court, despite reports of his con�  tinuing and flagrant debauchery. When Nicholas left Alexandra in charge  of Russia�s internal affairs in 1915, Rasputin influenced her appointment  of church officials and incompetent cabinet ministers. After several  attempts to remove his harmful influence, a group of noblemen including  Prince Felix Yusupov assassinated him by successively poisoning him,  shooting him, and finally throwing him into the ice-filled Neva River. The  Russian Revolution of 1917 followed weeks later.</p><p>Rastafarian \,ras-t9-'fer-e-3n\ Member of a political and religious  movement among blacks in Jamaica and several other countries. Rasta�  farians worship Haile Selassie, considering him the Messiah. They believe  that blacks are the Israelites reincarnated, who have been subjected to the  evil and inferior white race in divine punishment for their sins; they will  eventually be redeemed by repatriation to Africa and will compel the  whites to serve them. These beliefs, first enunciated in 1953, can be traced  to several independent prophets, particularly Marcus Garvey. As the  movement grew, ideas of repatriation tended to give way to either black  militancy or mysticism. The Rastafarian life usually includes vegetarian�  ism, the wearing of dreadlocks, and the smoking of marijuana.</p><p>Rastatt and Baden Vra- I shtat... , bad- 3 n\, treaties of (March 6 and  Sept. 7, 1714) Two peace treaties between Charles VI, the Holy Roman  emperor, and France that ended Charles�s attempt to continue the War of  the Spanish Succession.

The black rat {Rattus rat�  tus) and the Norway rat {R. norveg-  icus) are the aggressive, omnivorous  animals commonly associated with  the name. They prefer areas of  human habitation, where they can  easily find food. They have keen  senses and can climb, jump, burrow,  or gnaw their way into seemingly  inaccessible places. They reproduce  extremely rapidly (up to 150 offspring a year) and have few natural preda�  tors. Rats transmit numerous human diseases and have often destroyed  grain supplies. The black rat is about 8 in. (20 cm) long, excluding the  slightly longer tail. The Norway rat (also called the brown, barn, sewer,  or wharf rat) has proportionately smaller ears and a shorter tail. Labora�  tory rats are strains of the Norway rat. The name rat is applied, without  scientific basis, to other rodents (e.g., kangaroo rat, wood rat).</p><p>rat snake Any of 40-55 snake species in the genus Elaphe (family Col-  ubridae) and similar forms, found in  woodlands and barnyards in North  America, Europe, and Asia. Nonven-  omous, they kill rats and mice by  constriction, and also eat eggs and  poultry. Some hunt birds in trees.</p><p>These egg-laying snakes are nor�  mally slow and docile, but in self-  defense they vibrate the tail,  discharge a foul liquid, and strike  from an upreared position.

July 21, 1967, New York, N.Y., U.S.) British actor. He made his  stage debut in 1911 and later played classical roles in London and New  York City. From 1924 he appeared in Hollywood movies, often in romantic  roles. With his distinctive voice and gaunt appearance, he was cast as a vil�  lain in several swashbuckling movies starring Tyrone Power and Errol  Flynn. He won praise for his roles in Romeo and Juliet (1936) and If I Were  King (1938), but he became best known for portraying Sherlock Holmes in  a series of films that began with The Hound of the Baskervilles (1939).</p><p>Rathenau \'ra-t 3 n-,au,\ English Vra-thon-.auV, Walther (b.

In World War I he  organized the conservation and distribution of raw materials for the War  Ministry. In 1918 he cofounded the liberal German Democratic Party and  supported cooperation with the Social Democratic Party. After serving as  minister of reconstruction (1921-22), he was appointed foreign minister  and negotiated the Treaty of Rapallo with the Soviet Union. Reviled by  extreme nationalists as a Jew and a promoter of �creeping Communism,�  he was assassinated.</p><p>Rathke Vrat-koX, Martin H(einrich) (b. Aug. 25, 1793, Danzig,  Prussia�d. Sept. 3, 1860, Konigsberg) German anatomist and embryolo�  gist. He was the first to describe gill slits and gill arches in mammal and  bird embryos. He thought they were vestigial gills but recognized their  significance in development of the associated blood vessels. He first  described the Rathke pouch (1839), an embryonic structure that develops  into the pituitary gland�s anterior lobe. He also did pioneering marine  zoology research.</p><p>ratio Quotient of two values. The ratio of a to b can be written a:b or  as the fraction alb. In either case, a is the antecedent and b the conse�</p><p>quent. Ratios arise whenever comparisons are made. They are usually  reduced to lowest terms for simplicity. Thus, a school with 1,000 students  and 50 teachers has a student/teacher ratio of 20 to 1. The ratio of the  width to the height of a rectangle is called an aspect ratio, an example of  which is the golden ratio of classical architecture. When two ratios are set  equal to each other, the resulting equation is called a proportion.</p><p>rational number Any number that can be represented as the quotient  of two integers (i.e., the denominator cannot equal zero). The set of ratio�  nal numbers includes all integers as well as all fractions. In decimal form,  rational numbers are either terminating or repeating decimals.</p><p>rational psychology Metaphysical discipline that attempted to deter�  mine the nature of the human soul by a priori reasoning. In Christian Wolff�s  division of metaphysics, rational psychology was one of three disciplines  included under the heading of �special metaphysics� (the others being  rational cosmology and rational theology). Immanuel Kant, in his Critique of  Pure Reason , criticized the pretensions of rational psychology.</p><p>rationalism Philosophical view that regards reason as the chief source  and test of knowledge. Rationalism has long been the rival of empiricism,  the doctrine that all knowledge of matters of fact ultimately derives from,  and must be tested by, sense experience. As against this doctrine, ratio�  nalism holds reason to be a faculty that can lay hold of truths beyond the  reach of sense perception, both in certainty and in generality. In stressing  the existence of a �natural light,� rationalism also has been the rival of  systems claiming esoteric knowledge, whether from mystical experience,  revelation, or intuition, and has been opposed to various irrationalisms  that tend to stress the biological, the emotional or volitional, the uncon�  scious, or the existential at the expense of the rational.</p><p>rationing Government allocation of scarce resources and consumer  goods, usually adopted during wars, famines, or other national emergen�  cies. Rationing according to use prohibits the less important uses of a com�  modity (e.g., the use of gasoline for pleasure trips as opposed to work-  related travel). Rationing by quantity limits the amounts of a commodity  available to each claimant (e.g., a pound of butter per month). Rationing by  value limits the amount of money consumers can spend on commodities  that are difficult to standardize (e.g., clothing). Point rationing assigns a  point value to each commodity and allocates a certain number of points to  each consumer. These can be tracked through coupons, which are issued to  consumers and must be exchanged for the approved amounts of rationed  goods. Consumers in a rationed economy are usually encouraged to save  their money or invest in government bonds so that unspent money will not  be used for unrationed items or purchases on the black market.</p><p>ratite \'ra-,tlt\ Any bird species that cannot fly because its smooth, or  raftlike, sternum (breastbone) lacks a keel to which flight muscles can be  anchored.

His best-known work, Separate Tables (1955; film,  1958), explores the isolation created by rigidly imposed social conven�  tions. His other plays include The Browning Version (1948), Ross (1960),  and A Bequest to the Nation (1970). He wrote screenplays for the film  adaptations of his plays and for The Yellow Rolls-Royce (1965) and Good�  bye Mr. Chips (1969).</p><p>rattlesnake Any of about 30 spe�  cies in two genera of New World pit  vipers having a tail rattle that pro�  duces a buzzing sound when  vibrated.

His �combine� paintings of the  1950s, incorporating objects such as soda bottles, traffic barricades, and  stuffed birds, anticipated the Pop art movement. In later work, he used  silkscreen and other techniques to transfer images from commercial print  media and his own photographs to canvas, reinforcing the images and  unifying them compositionally with bold strokes of paint.

Dec. 14, 1953, St. Augustine, Fla.) U.S.  short-story writer and novelist. Rawlings worked as a journalist before  moving to backwoods Florida and devoting herself to fiction. Taking her  material from the people and land around her, she wrote richly atmo�  spheric works that resemble vivid factual reporting and are noted for their  magical descriptions of landscape. Her best-known novel is The Yearling  (1938, Pulitzer Prize), about a boy from a hardscrabble family and the  fawn he adopts. Her later works include Cross Creek (1942) and The  Sojourner (1953).</p><p>Rawls, John (b. Feb. 21,1921, Baltimore, Md., U.S.�d. Nov. 24,2002,  Lexington, Mass.) U.S. political philosopher. He taught at Cornell Univer�  sity (1962-79) and later at Harvard University. He wrote primarily on  political philosophy and ethics. His Theory of Justice (1971) is widely rec�  ognized as the major work in 20th-century political philosophy. In that  work and others Rawls sought to develop a conception of justice appro�  priate to a democratic society. He believes that utilitarianism, which enjoins  maximizing overall happiness, inadequately protects freedom and equality,  the core liberal and democratic values. Following Jean-Jacques Rousseau  and Immanuel Kant, he appealed to the idea of a social contract: he depicted  justice as the result of a hypothetical agreement among free persons acting  from a position of equal right. To insure a fair, impartial agreement, Rawls  situated parties to it equally by imposing a �veil of ignorance�: parties do  not know any particular facts about themselves and others (e.g., their tal�  ents, social class, wealth, or religious and other values) or even facts about  history or their society. From this �original position� Rawls contends that  free persons would agree to a liberal egalitarian conception of justice, or  �justice as fairness.� This conception comprises two principles: (1) certain  basic liberties, such as freedom of  thought and association, are so  important that they take precedence  over other social values, such as eco�  nomic efficiency and improving the  welfare of the poor; (2) offices and  positions of authority are to be open  to all under conditions of equality of  opportunity.</p><p>ray Any of 300-350 mostly marine  species of cartilaginous fish (order  Batoidei) found worldwide and clas�  sified as ELECTRIC RAYS, SAWFISHES,</p><p>skates, and stingrays.

March 10, 1928, Alton, Ill., U.S.�d. April 23,  1998, Nashville, Tenn.) Assassin of Martin Luther King, Jr. Ray was a petty  criminal who had been sentenced several times to prison; he escaped from  the Missouri state prison in 1967. In Memphis, Tenn., on April 4, 1968,  he shot King from the window of a rooming house as King emerged from  his motel room across the street. Ray fled to Toronto, London, Lisbon,  and back to London, where he was arrested on June 8. In Memphis he  pleaded guilty and was sentenced to 99 years in prison. Months later, he  recanted his confession, without effect. Later in life, his unsuccessful pleas  to have his case reopened were supported by some civil rights leaders,  notably the King family.</p><p>Ray, John (b. Nov. 29, 1627, Black Notley, Essex, Eng.�d. Jan. 17,  1705, Black Notley) British naturalist and botanist. He attended Cam�  bridge University and spent many years there as a fellow. With Francis Wil-  lughby (1635-1672) he undertook a complete catalog of living things, of  which he published numerous volumes. His enduring legacy to botany was  the establishment of species as the ultimate unit of taxonomy. He attempted  to base his systems of classification on all the structural characteristics of  organisms, including internal anatomy, rather than on a single feature. By  insisting on the importance of lungs and heart structure, he effectively  established the class of mammals, and he divided insects according to the  presence or absence of multiple metamorphoses. Coming closer to a truly  natural system of taxonomy than had any of his contemporaries, Ray  helped make possible Carolus Linnaeus�s later contributions.</p><p>Ray, Man See Man Ray</p><p>Ray, Nicholas orig.

He studied architecture and drama and began directing plays in  the mid-1930s. After working in New York with John Houseman and Elia  Kazan, he followed them to Hollywood, where he directed They Live by  Night (1948). Ray was praised for demonstrating a personal style in mov�  ies such as In a Lonely Place (1950), The Lusty Men (1952), Johnny Gui�  tar (1954), and the landmark film of youthful rebellion, Rebel Without a  Cause (1955).

In 1873 he suc�  ceeded to his father�s title and built a research laboratory on his estate.  He taught physics at Cambridge University (1879-84) and was secretary  of the Royal Society (1884-95). His research included work on electro�  magnetism, colour, acoustics, and diffraction gratings, and his theory  explaining the blue colour of the sky evolved into the Rayleigh scattering  law. In 1904 he was awarded the Nobel Prize for Physics for his isola�  tion of argon. In 1908 he became chancellor of Cambridge University.  His influential Theory of Sound (1877, 1878) examines questions of vibra�  tions and resonance of media.</p><p>Rayleigh scattering Dispersion of electromagnetic radiation by par�  ticles with radii less than Vio the wavelength of the radiation. It is named  for Baron Rayleigh, who described it in 1871. Since blue light is at the  short wavelength end of the visible spectrum, it is scattered in the atmo�  sphere much more than the longer-wavelength red light. This causes the  blue colour of the sky, since the observer sees only the scattered light.  The Rayleigh laws predict the variation of the intensity and the polariza�  tion of scattered light.</p><p>Raymond IV French Raimond known as Raymond of Saint-  Gi lies \sa n -'zhel\ (b. 1041 or 1042, Toulouse, county of Toulouse�d.

Though he  lost his title by decree of the fourth Lateran Council (1215), despite the  effort of Pope Innocent III to arrange a compromise, he regained most of  his lands by conquest. Twice excommunicated, he was refused Christian  burial.</p><p>Raymond VII French Raimond (b. July 1197, Beaucaire, France�d.  Sept. 27, 1249, Millau) Count of Toulouse (1222^-9). He helped recover  lands taken from his father, Raymond VI, and negotiated a truce (1223)  with land-hungry Crusaders from northern France. For failing to suppress  the heretical Cathari, he was excommunicated (1226) and subjected to a  French invasion. He ceded territory to France by treaty and agreed to per�  mit the Albigensian Crusade to continue in Languedoc (1229). Allied with  Henry III of England, he rebelled unsuccessfully against Louis VIII of  France (1242) and was forced to accept greater French authority over  Toulouse.</p><p>Raymond, Antonin (b.

He assisted Frank Lloyd Wright in building the Impe�  rial Hotel, Tokyo (1916). Remaining in Japan, he and his partner, Ladislav  Rado, built numerous structures, mostly for Americans. One of the few  Modernist architects working in Japan at the time, he influenced such  Japanese architects as Yoshimura Junzo and Maekawa Kunio. Among his  works were the Reader�s Digest Building, Tokyo (1951; since destroyed),  and the Nagoya International School (opened 1967), a circular structure  serving a flexible, progressive educational program.</p><p>Raymond of Penafort V.pan-yo-'forA, Saint Spanish Raimundo  (b. c. 1185, Penafort, near Barcelona�d.

The style�s name reflects the radiating character of the rose window. Other  features include the thinning of vertical supporting members, the enlarge�  ment of windows, and the combination of the triforium gallery and clere�  story into one large glazed area, until walls became largely  undifferentiated screens of tracery, mullions, and glass. Amiens Cathedral  (1220-70) is cited as its earliest manifestation.

In 1667 he led a band of newcomers to establish an  outpost on the upper Don River. They raided Russian and Persian settle�  ments on the Caspian Sea (1667-70), acquiring great fame and wealth.  He then led his Cossack anarchists on a campaign into the Volga River  region, where he was joined by disaffected peasants. After seizing  Tsaritsyn (now Volgograd), Astrakhan, and Saratov, his force of 20,000  undisciplined rebels was defeated by the Russian army at Simbirsk. Razin  was captured, tortured, and executed.

RCA was founded as the Radio Corp. of  America by General Electric in 1919 to acquire Marconi Wireless Tele�  graph Co. of America, at that time the only company capable of handling  commercial transatlantic radio communications. RCA founded NBC in  1926 to manage radio broadcasting operations for GE, AT&amp;T, and West-  inghouse. An antitrust suit against the three latter companies in 1932  caused RCA and its NBC unit to become independent. In 1939 RCA  developed the first experimental television set, and its black-and-white sets  went on the market seven years later. After consolidating most of RCA�s  operations into GE�s businesses, in 1987 General Electric sold RCA�s  consumer-electronics division to the French corporation Thomson-Brandt,  SA (later Thomson SA).

He was believed to sail across the sky in his solar bark and at  night to travel in another bark through the underworld, where he had to  vanquish a serpent before he could be born again. As the creator, he rose  from the ocean of chaos, creating himself and then engendering eight  other gods. From the 4th dynasty, kings held the title Son of Re, and Re  later became part of the throne name they adopted at accession and was  appended to the names of such gods as Amon and Sebek.</p><p>reactance Measure of the opposition that an electrical circuit or a part  of a circuit presents to electric current (see electrical impedance) insofar as  the current is varying or alternating. Steady electric currents flowing along  conductors in one direction undergo opposition called electrical resistance,  but no reactance. Reactance is present in addition to resistance when con�  ductors carry alternating current. Reactance also occurs for short intervals  when direct current is changing as it approaches or departs from steady  flow (e.g., when switches are closed or opened). Reactance is of two types,  inductive and capacitive. Inductive reactance is associated with the vary�  ing magnetic field that surrounds a wire or a coil carrying a current.  Capacitive reactance is associated with the changing electric field between  two conducting surfaces (plates) separated from each other by an insu�  lating medium. The ohm is the unit of reactance.</p><p>reaction, heat of Amount of heat that must be added or removed dur�  ing a chemical reaction to keep all substances involved at the same tem�  perature. If it is positive (heat must be added), the reaction is endothermic;  if it is negative (heat is given off), the reaction is exothermic. Accurate  heat of reaction values are needed for proper design of equipment used  in chemical processes; they are usually estimated from compiled tables  of thermodynamics data (heats of formation and heats of combustion of  many known materials). The activation energy is unrelated to the heat of  reaction.</p><p>reaction rate Speed at which a chemical reaction proceeds, in terms of  amount of product formed or amount of reactant consumed per unit of  time. The reaction rate depends on the nature of the reacting substances  and the type of chemical change, as well as temperature and pressure,  especially if GASes are involved. In general, the reactions of ions occur  very rapidly, but those in which covalent bonds are formed or broken are  slower. Catalysts usually accelerate reaction rates. The prediction, mea�  surement, and interpretation of reaction rates are subjects of the branch  of chemistry known as chemical kinetics.

His nov�  els expose, with passionate indignation, the social injustices of his times.  He is best remembered for the historical romance The Cloister and the  Hearth (1861). His other novels include It Is Never Too Late to Mend  (1856), attacking prison conditions; Hard Cash (1863), on the abuse of  mental patients; and Put Yourself in His Place (1870), about terrorism by  trade unionists.</p><p>Reader's Digest U.S.-based monthly magazine.

Reading was a Danish  encampment as early as ad 871. It was given a town charter by King Henry  III in 1253; that charter was confirmed by succeeding sovereigns. Between  the 12th and 16th centuries Reading was dominated by a struggle for  privileges between the Benedictine abbey founded in 1121 and the emer�  gent merchants� guild. By the 17th century the town�s trade, notably in  clothing, had begun to decline. In the 18th century the chief trade was in  malt. In the city�s public gardens are the ruins of the abbey, which was  dissolved by Henry VIII. The structure was destroyed during the English  Civil Wars, during which time the town in general also suffered severely.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1596 I ready-made &#x25BA; rebbe</p><p>In Reading Gaol, adjoining the ruins, Oscar Wilde was imprisoned, and  it was there that he wrote The Ballad of Reading Gaol.

Duchamp�s anti-aesthetic ges�  tures made him one of the leading Dadaists of his day, and his ready�  made concept, though widely regarded for decades as an insult to art, was  adapted by such later artists as Robert Rauschenberg, Andy Warhol, and  Jasper Johns.</p><p>Reagan Vra-g9n\, Ronald W(ilson) (b. Feb. 6, 1911, Tampico, Ill.,  U.S.�d. June 5, 2004, Los Angeles, Calif.) 40th president of the U.S.  (1981-89). He attended Eureka College and worked as a radio sports  announcer before going to Hollywood in 1937. In his career as a movie  actor, he appeared in more than 50 films and was twice president of the  Screen Actors Guild (1947-52, 1959-60). In the mid-1950s he became a  spokesman for the General Electric Co.; he hosted its television theatre  program from 1954 to 1962. Having gradually changed his political affili�  ation from liberal Democrat to conservative Republican, he was elected  governor of California in 1966 and served two terms. In 1980 he defeated  incumbent Pres. Jimmy Carter to become president. Shortly after taking  office, he was wounded in an assassination attempt. His administration  adopted policies based on supply-side economics in an effort to promote  rapid economic growth and reduce the federal deficit. Congress approved  many of his proposals (1981), which succeeded in lowering inflation but  doubled the national debt by 1986. He began the largest peacetime mili�  tary buildup in U.S. history; in 1983 he proposed construction of the Stra�  tegic Defense Initiative. His administration concluded a treaty with the  Soviet Union to restrict intermediate-range nuclear weapons, conducted a  proxy war against Nicaragua through its support of the Contras, and  invaded Grenada ostensibly to prevent the island nation from becoming  a Soviet outpost. He was reelected by a large margin in 1984. Beginning  in 1986, the Iran-Contra Affair temporarily weakened his presidency.  Though his intellectual capacity for governing was often disparaged by  his critics, his affability and artful communication skills enabled him to  pursue numerous conservative policies with conspicuous success, and his  tough stance toward the Soviet Union is often credited with contributing  to the demise of Soviet communism. In 1994 he revealed that he had  Alzheimer disease.</p><p>real and personal property Basic types of property in English  common law, roughly corresponding to the division between immovables  and movables in civil law.

The counting numbers, integers, ratio-  Jj nal numbers, and irrational numbers are all real numbers. Real numbers are</p><p>used in measuring continuously varying quantities (e.g., size, time), in  contrast to measurements that result from counting. The word real dis�  tinguishes them from the imaginary numbers.</p><p>realism In the visual arts, an aesthetic that promotes accurate, detailed,  unembellished depiction of nature or of contemporary life. Realism rejects  imaginative idealization in favour of close observation of outward appear�  ances. It was a dominant current in French art between 1850 and 1880. In  the early 1830s the painters of the Barbizon school espoused realism in their  faithful reproduction of the landscape near their village. Gustave Courbet  was the first artist to proclaim and practice the realist aesthetic; his Burial  at Ornans and The Stone Breakers (1849) shocked the public and critics  with their frank depiction of peasants and labourers. In his satirical cari�  catures, Honore Daumier used an energetic linear style and bold detail to  criticize the immorality he saw in French society. Realism emerged in the  U.S. in the work of Winslow Homer and Thomas Eakins. In the 20th century  German artists associated with the Neue Sachlichkeit worked in a realist  style to express their disillusionment after World War I. The Depression-era  movement known as Social Realism adopted a similarly harsh realism to  depict the injustices of U.S. society. See also naturalism.</p><p>realism In literature, the theory or practice of fidelity to nature or to real  life and to accurate representation without idealization of everyday life.  The 18th-century works of Daniel Defoe, Henry Fielding, and Tobias Smol�  lett are among the earliest examples of realism in English literature. It  was consciously adopted as an aesthetic program in France in the mid-  19th century, when interest arose in recording previously ignored aspects  of contemporary life and society; Gustave Flaubert�s Madame Bovary  (1857) established the movement in European literature. The realist  emphasis on detachment and objectivity, along with lucid but restrained  social criticism, became integral to the novel in the late 19th century. The  word has also been used critically to denote excessive minuteness of detail  or preoccupation with trivial, sordid, or squalid subjects. See also natu�  ralism.</p><p>realism In philosophy, any viewpoint that accords to the objects of  human knowledge an existence that is independent of whether they are  being perceived or thought about. In the metaphysical debate concerning  universals, realism is opposed to nominalism, which denies that universals  have any reality at all (except as words), and to conceptualism, which  grants universals reality but only as concepts in the mind. Against ideal�  ism and phenomenalism, realism asserts the independent existence of mate�  rial objects and their qualities. Similarly, moral realism holds that the moral  qualities of things and actions (such as being good or bad, right or wrong)  belong to the things or actions themselves and are not to be explained in  terms of the subject�s feelings of approval or disapproval. In opposition  to conventionalism, realism holds that scientific theories are objectively  true (or false) based on their correspondence (or lack of it) to an inde�  pendently existing reality.</p><p>realpolitik Politics based on practical objectives rather than on ideals.  The word does not mean �real� in the English sense but rather connotes  �things��hence a politics of adaptation to things as they are. Realpolitik  thus suggests a pragmatic, no-nonsense view and a disregard for ethical  considerations. In diplomacy it is often associated with relentless, though  realistic, pursuit of the national interest.</p><p>reamer Rotary cutting tool of cylindrical or conical shape, used for  enlarging and finishing to accurate dimensions holes that have been  drilled, bored, or cored.

His  Memoirs Serving as a Natural History of Insects (1734�42), though unfin�  ished, was a milestone in entomological history.</p><p>rebate Retroactive refund or credit given to a buyer who has purchased  a product or service. Fair and equitable rebates are used simply as incen�  tives available to all customers. So-called deferred (or exclusive-  patronage) rebates are used by large vendors of perishables and consumer  durable goods. To receive such a rebate, the purchaser must agree to buy  certain goods or services exclusively from a particular vendor for a fixed  period of time. Rebating was a common pricing tactic in the 19th century,  often used by large companies to undercut competition from smaller firms.  The U.S. railroad industry practiced price discrimination by granting secret  rebates to important customers; the rebates granted to Standard Oil Co.  helped it acquire a monopoly over the oil industry. Governments occa�  sionally sponsor rebates on previously paid taxes such as property,  income, or sales taxes. Tax rebates can be used to stimulate the economy,  to return excess revenue to taxpayers, or to encourage specific actions  such as energy conservation.</p><p>rebbe See rabbi</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Recamier &#x25BA; rectum I 1597</p><p>Recamier Vra-kam-'yaX, Madame de orig. Jeanne-Francoise-  Julie-AdelaVde Bernard in full Jearme-Francoise-Julie-  AdelaYde, dame de Recamier (b. Dec. 4, 1777, Lyon, France�d.  May 11, 1849, Paris) French hostess. Daughter of a prosperous banker,  she married a wealthy banker and began to entertain widely. Her great  charm and wit attracted to her salon most of the important political and  literary figures of early 19th-century Paris, including many opponents of  Napoleon, who exiled her in 1805. After Napoleon�s defeat in 1815 she  returned to Paris, where in her later years Rene, viscount de Chateaubriand  became her companion and the central figure in her salon. Her friend Ger�  maine de Stael created her literary portrait in the novel Corinne.</p><p>receivership In law, state of being in the hands of a receiver, a person  appointed by the court to administer, conserve, rehabilitate, or liquidate the  assets of an insolvent corporation for the protection or relief of creditors. It  is a legal solution to a financial difficulty; it does not necessarily entail the  termination of the corporate charter. See also bankruptcy, insolvency.</p><p>Recent epoch See Holocene epoch</p><p>recession Downward trend in the business cycle characterized by a  decline in production and employment, which in turn lowers household  income and spending. Even though not all households and businesses  experience actual declines in income, they become less certain about the  future and consequently delay making large purchases or investments.  Consumers buy fewer durable household goods, and businesses are less  likely to purchase machinery and equipment and more likely to use up  existing inventory instead of adding goods to their stock. This drop in  demand leads to a corresponding fall in output and thus worsens the eco�  nomic situation. Whether a recession develops into a severe and prolonged  depression depends on a number of circumstances. Among them are the  extent and quality of credit extended during the previous period of pros�  perity, the amount of speculation permitted, the ability of government  monetary and fiscal policies to reverse (or minimize) the downward trend,  and the amount of excess productive capacity. Compare depression.</p><p>recessiveness Failure of one of a pair of genes (alleles) present in an  individual to express itself in an observable manner because of the greater  influence, or dominance, of its opposite-acting partner. Both alleles affect  the same inherited characteristic, but the presence of the recessive gene  cannot be determined by observation of the organism; that is, though  present in the organism�s genotype (gene makeup), the recessive trait is  not evident in its phenotype (observable characteristics). The term reces�  sive is applied both to the trait in the organism having the alleles of a gene  pair in the recessive condition and to the allele whose effect can be masked  by another allele of the same gene.</p><p>Recife \ri-'se-fe\ Port and city (pop., 2003: city, 1,461,300; metro, area,  3,466,214), northeastern Brazil. Founded by the Portuguese in the first  half of the 16th century, it was raided and sacked by British privateers in  1595. It was later occupied by the Dutch (1630-54). It has been called  the Venice of Brazil because it is crossed by waterways, and areas of the  city are linked by numerous bridges. Situated at the confluence of the  Capibaribe and Beberibe rivers, it is one of the leading ports of Brazil,  with extensive modern port facilities. It is an educational and cultural  centre, with several universities and theatres.</p><p>reciprocity \ 1 re-s9- , pra-so-te\ In international trade, the granting of  mutual concessions on tariffs, quotas, or other commercial restrictions.  Reciprocity implies that these concessions are neither intended nor  expected to be generalized to other countries with which the contracting  parties have commercial treaties. Reciprocity agreements may be made  between individual countries or groups of countries. Membership in the  World Trade Organization to some extent precludes the signing of reci�  procity treaties because WTO nations are obliged to grant most-favored-  nation treatment to all other members.</p><p>recitative \,re-s9-t3-'tev\ Style of accompanied solo singing that imitates  the rhythms and tones of speech. Representing an attempt at an ideally  expressive musical text setting, which the ancient Greeks were thought to  have mastered, it came into existence in tandem with opera c. 1600, the first  operas being largely written in recitative. Recitative style gradually began  to separate from lyrical aria style. Regular alternation of recitative with aria  became the rule for both opera and cantata, and recitative became essential  to the dramatic oratorio as well. It remains basic to operatic composition;  the presence of recitative (as opposed to spoken dialogue) most clearly dis�  tinguishes opera from the musical and related genres.</p><p>recognizance \ri-'kag-n3-z3nts\ In law, obligation entered into before  a court or magistrate requiring the performance of an act (e.g., appear�  ance in court), usually under penalty of a money forfeiture. The most  common use of recognizance is in connection with bail in criminal cases.  The accused may also be released on his �own recognizance� when no  bail is required.</p><p>recombination In genetics, regrouping of the maternal and paternal  genes during the formation of sex cells (gametes). Recombination occurs  randomly in nature as a normal event of meiosis. It is enhanced by crossing-  over (see linkage group). Recombination acts to ensure that no two daugh�  ter cells are identical, nor are any identical in genetic content to the parent  cell. Laboratory study of recombination has contributed significantly to  the understanding of genetic mechanisms, allowing scientists to map  chromosomes, identify linkage groups, isolate the causes of certain genetic  mistakes, and manipulate recombination itself by transplanting genes  from one chromosome to another. See also genetic engineering, molecular  BIOLOGY.</p><p>recompression chamber See hyperbaric chamber</p><p>Reconstruction (1865-77) Period after the American Civil War in  which attempts were made to solve the political, social, and economic  problems arising from the readmission to the Union of the 11 Confeder�  ate states that had seceded at or before the outbreak of war. Pres. Abra�  ham Lincoln planned to readmit states in which at least 10% of the voters  had pledged loyalty to the Union. This lenient approach was opposed by  the Radical Republicans, who favoured the harsher measures passed in the  Wade-Davis Bill. Pres. Andrew Johnson continued Lincoln�s moderate  policies, but enactment in the South of the black codes and demand in the  North for stricter legislation resulted in victories for Radical Republicans  in the congressional elections of 1866. Congress then passed the Recon�  struction Acts of 1867, which established military districts in the South  and required the Southern states to accept the 14th and 15th Amendments  to the Constitution. Southern resentment of the imposed state govern�  ments, which included Republicans, carpetbaggers, and scalawags, and of  the activities of the Freedmen's Bureau led to the formation of terrorist  groups such as the Ku Klux Klan and the Knights of the White Camelia.  By the 1870s conservative Democrats again controlled most state gov�  ernments in the South. Though Reconstruction has been seen as a period  of corruption, many constructive legal and educational reforms were  introduced. The Reconstruction era led to an increase in sectional bitter�  ness, dissension regarding the rights of blacks, and the development of  one-party politics in the South.</p><p>Reconstruction Finance Corporation (RFC) U.S. government  agency established (1932) to provide loans to railroads, banks, and busi�  nesses. The RFC was an attempt by Pres. Herbert Hoover to counter the  early effects of the Great Depression by rescuing institutions from default.  It was widely used by Pres. Franklin Roosevelt in the New Deal and to  finance defense plants in World War II. After the war, the RFC�s powers  and functions were gradually transferred to other agencies.</p><p>Reconstructionism Movement that originated in U.S. Judaism in the  1920s. It regards Judaism only as a specific human culture, rejects the  tradition of a transcendent deity who made a covenant with his chosen  people, and does not accept the Bible as the inspired word of God. Its prin�  ciples, as enunciated by Mordecai Menahem Kaplan, are based on the belief  that Jews can live a distinctively Jewish cultural life without being reli�  giously observant. Reconstructionists today number about 60,000.</p><p>record player See phonograph</p><p>recorder In music, a cylindrical, usually wooden, wind instrument with  fingerholes. As a Apple (duct) flute, its rather soft tones are produced by  air blown against the sharp edge of an opening in the tube. The large  recorder family includes instruments ranging from the sopranino to the  contrabass. The recorder emerged in the 14th century and was widely used  in ensembles and orchestras in the late Renaissance and throughout the  Baroque era. Displaced by the transverse flute after the mid-18th century,  it was revived in the 20th century.</p><p>rectum End segment of the large intestine (see digestion) in which feces  accumulate just prior to discharge. It is 5-6 in. (13-15 cm) long and lined  with mucous membrane. One set of muscles separates it from the anal  canal; another shortens it to expel feces. The rectal walls distend as feces  enter, which stimulates the urge for defecation.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1598 I recycling &#x25BA; Red River Indian War</p><p>recycling or materials salvage Recovery and reuse of materials  from consumed products. The main motives for recycling have been the  increasing scarcity and cost of natural resources (including oil, gas, coal,  mineral ores, and trees) and the pollution of air (see air pollution), water  (see water pollution), and land by waste materials. There are two types of  recycling, internal and external. Internal recycling is the reuse in a manu�  facturing process of materials that are a waste product of that process, and  is common in the metals industry (see scrap metal). External recycling is  the reclaiming of materials from a product that is worn out or no longer  useful; an example is the collection of old newspapers and magazines for  the manufacture of newsprint or other paper products.</p><p>Red Army Army of the Soviet Union. Formed in the aftermath of the  Russian Revolution of 1917, its first civilian leader was Leon Trotsky, who  proved a brilliant strategist and administrator. Formed of workers and  peasants, it initially lacked an officers� corps, and Trotsky was forced to  mobilize officers of the former imperial army until a new, politically reli�  able corps could be trained. The Communist Party placed commissars in  all army units to ensure political orthodoxy. Joseph Stalin purged the mili�  tary leadership in 1937, leaving the army demoralized and unprepared for  the German surprise attack in 1941. It recovered sufficiently by 1945 to  have forces numbering more than 11 million, surpassed in strength only  by the U.S. Army. In 1946 it was renamed the Soviet Army. In 1960 the  commissars� duties were transferred to army officers.

Its self-proclaimed aim was to undermine the Ital�  ian state and pave the way for a Marxist upheaval led by a �revolution�  ary proletariat.� Reputedly founded by Renato Curcio (b. 1945), it began  carrying out violent acts with firebombings (1970), escalating to kidnap�  pings (1971) and murders (1974), most notably that of Aldo Moro (1978).  At its height, it probably had 400 to 500 full-time members, perhaps 1,000  sporadic members, and a few thousand supporters. Arrest and imprison�  ment of many leaders and ordinary members greatly weakened the orga�  nization in the 1980s. However, a group calling itself the Red Brigades  claimed responsibility for several violent attacks in the 1990s and into the  21st century.</p><p>Red Cloud orig. Mahpiua Luta (b. 1822, on the Platte River,  Nebraska Territory, U.S.�d. Dec. 10, 1909, Pine Ridge Agency, S.D.)  American Indian leader. The principal chief of the Oglala Teton Dakota  (Sioux), he led the opposition of both the Sioux and the Cheyenne to the  U.S. government�s development of the Bozeman Trail to goldfields in the  Montana Territory (1865-67). Relentlessly attacking workers along the  route from Fort Laramie (in modern Wyoming) to Montana, he refused  offers to negotiate until the U.S. agreed to halt the project, whereupon he  laid down his arms and allowed himself to be settled on the Red Cloud  Agency in Nebraska.</p><p>Red Cross officially International Movement of the Red  Cross and Red Crescent formerly International Red Cross</p><p>Humanitarian agency with national affiliates worldwide. Established for  the care of victims of battle, it now aids in the general prevention and  relief of human suffering. It arose out of the work of Jean-Henri Dunant,  who proposed the formation of voluntary relief societies in all countries,  the first of which came into being in 1864. The name Red Crescent,  adopted in 1906 at the insistence of the Ottoman Empire, is used in Mus�  lim countries. In peacetime, the Red Cross aids victims of natural disas�  ters, maintains blood banks, and provides supplementary health care  services. In wartime, it serves as an intermediary between belligerents and  visits prisoner-of-war camps to provide relief supplies, deliver mail, and  transmit information between prisoners and their relatives. Its operating  principles are humanity, impartiality, and neutrality. Its headquarters are  in Geneva. Individual national organizations run community programs  and coordinate natural-disaster relief efforts. The American Red Cross was  founded by Clara Barton in 1881 and first chartered by Congress in 1900;  it runs the world�s largest blood-donor service. In 1901 Dunant received  the first Nobel Prize for Peace; the Red Cross itself received the prize in  1917, 1944, and 1963.</p><p>red deer Species of deer (Cervus elaphus), sometimes called elk, native  to Europe, Asia, and North Africa. It is found in woodlands and hunted</p><p>for sport and food. Red deer live in sexually segregated herds except in  the breeding season, when males (harts) fight for harems of females  (hinds). Red deer stand about 4 ft (1.2 m) high at the shoulder. The coat  is reddish brown, with lighter underparts and a light rump. The hart has  long, regularly branched antlers bearing 10 or more tines. There are sev�  eral endangered subspecies.

In ad 23 their forces were involved in the over�  throw of Wang Mang, the usurper whose reign had interrupted the Han  DYNASTY.</p><p>red-figure pottery Type of Greek  6th to the late 4th century bc. Devel�  oped in Athens c. 530 bc, the red-  figure pottery quickly overtook the  older black-figure pottery as the pre�  ferred style of vase painting. In red-  figure technique, the background  was painted black, and the outline  details on the figures were also  painted (rather than incised) in black,  but the rest of each figure was  unpainted and so retained the  orange-red colour of the natural  vase. By comparison with incising,  the painting of the details allowed  more flexibility in rendering human  form, movements, expressions, and  perspective. Since most of the orna�  mentation was narrative, such tech�  nical advantages were of utmost  importance.</p><p>red fox or common fox Either  of two fox species: Vulpes vulpes,  found throughout Europe, temperate  Asia, and northern Africa, and V.  fulva of North America. It has a red�  dish brown coat; the tail is white-tipped, and the ears and legs are black.  Red foxes are 36-42 in. (90-105 cm) long, including the 15-in. (38-cm)  tail; they stand about 16 in. (40 cm) tall and weigh about 15 lb (7 kg).  They eat small mammals, eggs, fruit, and birds. They are hunted for sport  and for their fur and are raised commercially for pelts. North American  red foxes exhibit black and silver colour phases.</p><p>Red Guards Paramilitary units of radical university and high-school  students formed during the Chinese Cultural Revolution. Responding in  1966 to Mao Zedong�s call to revitalize the revolutionary spirit of the Chi�  nese Communist Party, they went so far as to attempt to purge the country  of its pre-Communist culture. With a membership in the millions, they  attacked and persecuted local party leaders, schoolteachers, and other  intellectuals. By early 1967 they had overthrown party authorities in many  localities. Internal strife ensued as different units argued over which  among them best represented Maoism. In 1968 their disruption of indus�  trial production and urban life led the government to redirect them to the  countryside, where the movement gradually subsided.</p><p>Red River Chinese Yuan Chiang \'ywan-'jyaq\ Vietnamese Song  Hong Vsoq-'hoqV River, Southeast Asia.

It flows north, forming the Minnesota-North Dakota boundary, before  entering Manitoba and emptying into Lake Winnipeg after a course of 545  mi (877 km). It was explored in 1732-33 by the French voyageur Pierre  Gaultier de Varennes et de La Verendrye. The river, named after the red�  dish brown silt it carries, was a transportation link between Lake Win�  nipeg and the Mississippi River system. The Red River Settlement, an  agricultural colony, was founded in 1811 near Winnipeg. Its fertile val�  ley produces cereals, potatoes, and sugar beets and supports cattle rais�  ing.</p><p>red salmon See sockeye salmon</p><p>Red Sea Narrow inland sea between the Arabian Peninsula and Africa.  It extends southeast from Suez, Egypt, for about 1,200 mi (1,930 km) to  the Strait of Mandeb, which connects with the Gulf of Aden and then with  the Arabian Sea. It separates the coasts of Egypt, The Sudan, and Eritrea  from those of Saudi Arabia and Yemen. It contains some of the world�s  warmest and saltiest seawater. With its connection to the Mediterranean  Sea via the Suez Canal, it is one of the most heavily traveled waterways  in the world, carrying traffic between Europe and Asia. Its name is derived  from the colour changes observed in its waters.</p><p>red soil Any of a group of soils that develop in a warm, temperate, moist  climate under deciduous or mixed forests and that have thin organic and  organic-mineral layers overlying a yellowish-brown leached layer resting  on an illuvial (see illuviation) red layer. Red soils generally form from  iron-rich sedimentary rock. They are usually poor growing soils, low in  nutrients and humus and difficult to cultivate.</p><p>red spider See spider mite</p><p>Red Square Large public square, central Moscow. It lies north of the  Moskva River, adjacent to the Kremlin, and covers some 18 acres (7.3  hectares). Dating from the late 15th century, it has long been a busy mar�  ket area as well as a focal point in Russian history as the scene of execu�  tions, demonstrations, riots, and parades. Located around it are the State  Historical Museum (1875-81), the nine-towered Cathedral of St. Basil the  Blessed (1554-60), the former state department store GUM, and the tomb  of Vladimir Ilich Lenin. The square and Kremlin were designated a UNESCO  World Heritage site in 1990.</p><p>red tide Discoloration of seawater caused by dinoflagellates during peri�  odic blooms (population increases). Toxic substances released by these  organisms into the water may be lethal to fish and other marine life, and  they irritate the human respiratory system. Coastal resorts sometimes  close when breaking waves release the toxic substances into the air. The  causes of red tide are uncertain; it may require the confluence of several  natural phenomena, in which human influence may or may not play a part.</p><p>Red Turbans Peasant rebel movement of the mid-14th century that  flourished in northern China at the end of the Yuan dynasty (1206-1368).  The Red Turbans, whose leader was regarded as an incarnation of the  bodhisattva Maitreya, were opposed to alien Mongol rule; their movement  gained momentum from the famine that resulted from crop failures and  floods in the 1330s. Their maraud�  ing, which began in the 1350s, took  them as far as Korea, where their  incursions contributed to the down�  fall of the Koryo dynasty. Though  their rebellion was put down, rival  rebel forces under Zhu Yuanzhang  (1328-98) toppled the Yuan dynasty  and founded the Ming.

He made his Broadway debut  in 1959 and won acclaim in Barefoot in the Park (1963; film, 1967). The  blond, appealing Redford began acting in films in the mid-1960s. He  appeared with Paul Newman in the hits Butch Cassidy and the Sundance  Kid (1969) and The Sting (1973) and also starred in The Candidate (1972),  Jeremiah Johnson (1972), All the President�s Men (1976), The Natural  (1984), Out of Africa (1985), and Indecent Proposal (1993). His directo�  rial debut, Ordinary People (1980, Academy Award), was followed by  The Milagro Beanfield War (1988), A River Runs Through It (1992), Quiz  Show (1994), The Horse Whisperer (1998), and The Legend of Bagger  Vance (2000). He received an honorary Academy Award in 2001. In 1980  he founded the Sundance Institute to sponsor young filmmakers� works,  and by the 1990s its film festival was the major showcase for U.S. inde�  pendent films.</p><p>Redgrave, Sir Michael (Scudamore) (b.

Redi set up a  series of flasks containing different meats; half were sealed, half open. He  repeated the experiment, replacing  the sealed flasks with gauze-covered  flasks. Though the meat in all the  flasks rotted, Redi found that only in  the uncovered flasks, which flies had  entered freely, did the meat contain  maggots.

His delicate botanical prints were not only  framed as pictures but also used for china patterns. His Les Liliacees  (1802-15) contained 500 plates of lilies. However, roses became his spe�  cialty; Les Roses (1817-21) is considered his finest series, and its classic  images are still widely reproduced.</p><p>redox See oxidation-reduction</p><p>redshift Displacement of the spectrum of an astronomical object toward  longer wavelengths (visible light shifts toward the red end of the spec�  trum). In 1929 Edwin Hubble reported that distant galaxies had redshifts  proportionate to their distances (see Hubble's constant).

It grows in the coastal range from southwestern Oregon  to central California at elevations up to 3,300 ft (1,000 m). The genus  name commemorates the Cherokee Indian Sequoyah. The redwood is  sometimes called coast redwood to distinguish it from the Sierra redwood  (or big tree) and the Japanese redwood (or Japanese cedar). Redwoods are  the tallest living trees, often exceeding 300 ft (90 m) in height; one has  reached 368 ft (112 m). Typical trunk diameters are 10-20 ft (3-6 m) or  more. The redwood tree takes 400-500 years to reach maturity; some are  known to be more than 1,500 years old. As the tree ages, the lower limbs  fall away, leaving a columnar trunk. Redwood timber has been used for  furniture, shingles, fence posts, paneling, and fine wood objects. Today  many of the remaining redwood stands are protected (see Redwood  National Park; Sequoia National Park). See also dawn redwood.</p><p>Redwood National Park National park, northwestern comer of  California, U.S. It was established in 1968, expanded in 1978, and des�  ignated a World Heritage site in 1980. It preserves virgin groves of ancient  redwood trees, including the world�s tallest, 367.8 ft (112.1 m) high. It  also includes 40 mi (65 km) of scenic Pacific coastline. It covers an area  of 172 sq mi (445 sq km), including land in three state parks.</p><p>reed In botany, any of several species of large aquatic grasses, especially  the four species in the genus Phragmites (family Poaceae, or Gramineae).  The common, or water, reed (P. australis ) occurs along the margins of  lakes, fens, marshes, and streams from the Arctic to the tropics. It is a  broad-leaved grass, about 5-15 ft (1.5-5 m) tall, with feathery flower clus�  ters and stiff, smooth stems. Bur reed (genus Sparganium) and reed mace  (genus Typha ) are plants of other families. Dried reed stems have been used  for millennia as thatching and construction material, in basketry, for arrows  and pens, and in musical instruments (see reed instruments).</p><p>Reed/ Sir Carol (b. Dec. 30, 1906, London, Eng.�d. April 25, 1976,  London) British film director. He made his stage debut as an actor in 1924  and as a director in 1927, staging Edgar Wallace�s detective thrillers. He  began directing films in 1935, winning praise for The Stars Look Down  (1939), Night Train (1940), and the wartime semidocumentary The True  Glory (1945). Noted for his technical mastery of the suspense-thriller  genre, he had great success with Odd Man Out (1947), The Fallen Idol  (1948), and the classic The Third Man (1949). His later films include The  Key (1958), Our Man in Havana (1959), and Oliver! (1968, Academy  Award). He was the first British film director to be knighted.</p><p>Reed, John (b.

He  covered the revolutionary fighting in Mexico (1914) and was frequently  arrested for leading labour strikes. A war correspondent during World War  I, he became a close friend of Vladimir Lenin and witnessed the Russian  Revolution of 1917, described in his book Ten Days That Shook the World  (1919). He became head of the U.S. Communist Labor Party; indicted for  sedition, he escaped to the Soviet Union, where he died of typhus and  was buried beside the Kremlin wall.</p><p>Reed, Thomas B(rackett) (b.

As speaker of the House (1889-91, 1895-99) he intro�  duced procedural changes that strengthened legislative control by the  majority party and increased the power of the speaker and the Rules  Committee. The Reed Rules were attacked by opponents, who called Reed  �Czar Reed� for his vigorous promotion of their passage. Ten years later  the speaker�s powers were reduced.</p><p>Reed, Walter (b.

He received a  medical degree at age 18 from the  University of Virginia and entered  the Army Medical Corps in 1875. He  investigated the spread of typhoid  fever in military camps during the  Spanish-American War and was later  curator of the Army Medical  Museum in Washington, D.C. Yel�  low fever was believed to be spread  by bedding and other articles, but  Carlos Finlay had theorized in 1886  that it was carried by insects, and  Reed�s team ruled out a bacterium  suspected as the cause and found pat�  terns of spread that supported the  insect theory. Controlled experi�  ments proved transmission by mos�  quito bite, and in 1901 efforts to  combat an outbreak in Havana suc�  ceeded within 90 days.</p><p>Reed, Willis (b.

He led the Knicks to the  NBA title in 1970 and that year became the only player ever to win the  Most Valuable Player award for the regular season, the championships,  and the All-Star game. After retiring in 1974 he coached the Knicks  (1977-79) and other teams.</p><p>reed instrument Any musical wind instrument that sounds when the  player�s breath or air from a wind chamber causes a reed (a thin blade of  cane or metal) to vibrate, thereby setting up a sound wave in an enclosed  air column or in the open air. Reed pipes have single or double reeds. A  double reed, as in the oboe or bassoon, consists of two cane blades tied  together that beat against each other. A single reed may hit against a frame  (beating reeds), as in the clarinet or saxophone, or it may vibrate freely  through a closely fitting frame (free reeds), as in a harmonica or accor�  dion. Beating reeds in woodwind instruments depend on the pipe�s sound�  ing length (as determined by the fingering) to determine the pitch. Free  reeds have their own single pitch, determined by their thickness and  length. See also English horn; shawm.</p><p>Common, or American, redstart  (Setophaga ruticilla)</p><p>HAL H.

It was  subsequently banned.</p><p>reference frame or frame of reference Coordinate system that  allows description of time and position of points relative to a body. The  axes, or lines, emanate from a position called the origin. As a point moves,  its velocity can be described in terms of changes in displacement and  direction. Reference frames are chosen arbitrarily. For example, if a per�  son is sitting in a moving train, the description of the person�s motion  depends on the chosen frame of reference. If the frame of reference is the  train, the person is considered to be not moving relative to the train; if  the frame of reference is the Earth, the person is moving relative to the  Earth.</p><p>referendum and initiative Electoral devices by which voters  express their wishes regarding government policy or proposed legislation.  Obligatory referenda are those required by law. Optional referenda are  put on the ballot when a sufficient number of voters sign a petition demand�  ing that a law passed by the legislature be ratified by the people. Obliga�  tory and optional referenda should be distinguished from the voluntary  referenda that legislatures submit to voters to decide an issue or to test  public opinion. Initiatives are used to invoke a popular vote on a pro�  posed law or constitutional amendment. Direct initiatives are submitted  directly to the public after approval by a required number of voters; indi�  rect initiatives are submitted to the legislature. Switzerland has held about  half the world�s national referenda. Referenda also are common at the  local and state level in the U.S. In the late 20th century, referenda were  employed more frequently, particularly in Europe, to decide public policy  on voting systems, treaties and peace agreements (e.g., the Maastricht  Treaty), and social issues. See also plebiscite.</p><p>referential opacity See intentionality</p><p>reflection Change in the direction of propagation of a wave that strikes  a boundary between different media through which it cannot pass. When  a wave strikes such a boundary it bounces back, or is reflected, just as a  ball bounces off the floor. The angle of incidence is the angle between the  path of the wave and a line perpendicular to the boundary. The angle of  reflection is the angle between the same line and the path of the reflected  wave. All reflected waves obey the law of reflection, which states that the  angle of reflection is equal to the angle of incidence. The reflectivity of a  material is the fraction of energy of the oncoming wave that is reflected  by it.</p><p>reflex In biology, an automatic and inborn response to a stimulus that  involves a nerve impulse passing from a sensory nerve cell to a muscle  or gland without reaching the level of consciousness. Simple reflexes  include sucking, swallowing, blinking, scratching, and the knee jerk. Most  reflexes consist of complex patterns of many unconsciously coordinated  muscular actions that form the basis of much instinctive behavior in ani�  mals. Examples include walking, standing, the cat�s righting reflex, and  basic sexual acts.</p><p>Reform Bill of 1832 British parliamentary act that expanded the elec�  torate. It transferred voting privileges from the small rural boroughs con�  trolled by the nobility and gentry to the heavily populated but  underrepresented industrial towns. Conceived by Prime Minister Earl  Grey and introduced by Earl Russell, it passed in the House of Commons  three times but was opposed by the House of Lords until Grey�s threat to  create 50 new liberal peers (enough to carry the bill) finally brought their</p><p>agreement. The act redistributed seats in the Commons and lowered the  electoral qualifications to allow voting by small property owners (much  of the middle class).</p><p>Reform Bill of 1867 British parliamentary act that extended the vote  to many workingmen in the towns and cities, creating a major working-  class constituency for the first time. It was largely conceived by Benjamin  Disraeli, who hoped to expand his base of potential supporters.</p><p>Reform Bill of 1884-85 British parliamentary act that gave the vote  to agricultural workers. In 1885 the Redistribution Act equalized repre�  sentation on the basis of 50,000 voters for each member of parliament.  Together the two acts tripled the electorate and prepared the way for uni�  versal male suffrage.</p><p>Reform Judaism Religious movement that has modified or abandoned  many traditional Jewish beliefs and practices in an effort to adapt Juda�  ism to the modern world. It originated in Germany in 1809 and spread to  the U.S. in the 1840s under the leadership of Rabbi Isaac Mayer Wise.  Reform Judaism permits men and women to sit together in the synagogue,  incorporates choir and organ music in the service, holds a confirmation  ceremony for girls parallel to the boys� Bar Mitzvah, and does not observe  daily public worship, strict dietary laws, or the restriction of normal activi�  ties on the Sabbath. Its principles, initially enunciated in the Pittsburgh  Platform (1885), were revised in the Columbus Platform (1937) to support  traditional customs and ceremonies and the liturgical use of Hebrew. The  Reform movement continues to move toward Orthodox Judaism without  embracing all its strictures.</p><p>Reform Party Political movement in Canada in the 1830s and �40s.  Reformers in Upper Canada (later Ontario) led by Robert Baldwin urged  that provincial governments be made accountable to elected legislative  assemblies (�responsible government�). An extremist group led by Wil�  liam L. Mackenzie opposed the government in the rebellion of 1837.  Reformers in Lower Canada (later Quebec) joined Louis Papineau and his  Patriote Party. Reform Party candidates were elected premier (1842-43,  1848-54) in the province of Canada (union of Upper and Lower Canada).  In the 1850s the party split between a moderate group, which allied with  John Macdonald�s Progressive Conservative Party, and a radical faction,  the Clear Grits, from which the Liberal Party emerged.</p><p>Reforma, La (1854-76) Liberal political and social revolution in  Mexico under the principal leadership of Benito Juarez. It began with the  removal of the dictator Antonio Santa Anna and went on to abolish spe�  cial privileges of the church and the military, confiscate church lands,  suppress monasteries, institute civil marriage, establish a liberal federal�  ist constitution, and place the army under civilian control. Confiscated  church property was to be allocated to the landless, but this policy proved  to be La Reforma�s outstanding failure; in fact, the number and wealth  of large landholders increased. La Reforma came to a close when Porfirio  Diaz seized power in 1876.</p><p>Reformation or Protestant Reformation Break with Roman  Catholicism and the establishment of Protestant churches in the 16th cen�  tury. Though reformers such as Jan Hus and John Wycliffe attacked abuses  in the Roman Catholic church in the late medieval period, the Reforma�  tion is usually dated from 1517, when, according to tradition, Martin  Luther posted his Ninety-five Theses on the church door in Wittenberg. Vari�  ous Protestant denominations were soon founded by more radical reform�  ers, such as Huldrych Zwingli and the Anabaptists. John Calvin established  a theocracy in Geneva after his conversion to the Protestant cause. The  Reformation spread to other European countries and soon dominated  northern Europe. Spain and Italy remained resistant to Protestantism and  became centres of the Counter-Reformation. In England, where Henry VIII  founded the Church of England in 1534, the Reformation�s roots were  primarily political rather than religious, motivated by the pope�s refusal  to grant Henry a divorce. In Scotland the Calvinist John Knox led in the  establishment of the Presbyterian church (see Presbyterianism).</p><p>Reformed church Any of several Protestant groups strongly influ�  enced by Calvinism. They are often called by national names (Swiss  Reformed, Dutch Reformed, etc.). The name was originally used by all  the Protestant churches that arose out of the 16th-century Reformation but  was later confined to the Calvinistic churches of continental Europe, most  of which use a Presbyterian form of church government. The Calvinistic  churches of the British Isles became known as Presbyterian churches (see  Presbyterianism).</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1602 I refraction &#x25BA; Reggio di Calabria</p><p>refraction Change in direction of a wave as it leaves one medium and  enters another. Waves, such as sound and light waves, travel at different  speeds in different media. When a wave enters a new medium at an angle  of less than 90�, the change in speed occurs sooner on one side of the  wave than on the other, causing the wave to bend, or refract. When water  waves approach shallower water at an angle, they bend and become par�  allel to the shore. Refraction explains the apparent bending of a pencil  when it is partly immersed in water and viewed from above the surface.  It also causes the optical illusion of the mirage.</p><p>refractory Material that is not deformed or damaged by high tempera�  tures, used to make crucibles, incinerators, insulation, and furnaces, particu�  larly metallurgical furnaces. Refractories are produced in several forms:  molded bricks of various shapes, bulk granular materials, plastic mixtures  consisting of moistened aggregates that are rammed into place, castables  composed of dry aggregates and a binder that can be mixed with water and  poured like concrete, and mortars and cements for laying brickwork.</p><p>refrigeration Process of removing heat from an enclosed space or from  a substance in order to lower the temperature. In industrialized nations  and prosperous regions in the developing world, refrigeration is used  chiefly to store foodstuffs at low temperatures, thus inhibiting the destruc�  tive action of bacteria, yeasts, and molds. Many perishable products can  be frozen, permitting them to be kept for months and even years with  little loss in nutrition or flavour or change in appearance. See also air-  conditioning; cooling system; heat exchanger.</p><p>Components of a refrigerator. A compressor pressurizes the refrigerant gas, heating  it and forcing it through the system. The gas cools and liquefies in the condenser,  giving up its heat to the outside air. The liquid's pressure is lowered when it passes  through an expansion valve, and there is an associated further drop in tempera�  ture. The cold liquid then passes into the evaporator coils, where heat drawn from  the warmer refrigerator compartment causes it to vaporize. The gas is then returned  to the compressor to repeat the cycle.</p><p>� MERRIAM-WEBSTER INC.</p><p>refugee Person involuntarily displaced from his or her homeland. Until  the late 19th century and the emergence of fixed and closed national  boundaries, refugees were always absorbed by neighbouring countries.  Later, immigration restrictions and increasing numbers of refugees neces�</p><p>sitated special action to aid them. In 1921 Fridtjof Nansen created a  League of Nations Passport to allow refugees to move freely across  national boundaries. Refugee status at that time was accorded only if the  migrant�s departure was involuntary and asylum was sought in another  country. In 1938 the definition of refugee was expanded to include per�  sons with a well-founded fear of persecution because of ethnicity, reli�  gion, nationality, group membership, or political opinion. Later the  definition was expanded again to include persons who have fled from their  homes to other places in their own countries. Refugee status ceases to  apply when the migrant either is resettled or returns home. At the begin�  ning of the 21st century there were some 16 million refugees, including  nearly 4 million Palestinians; much of the rest of the world�s refugees  were in Asia (particularly Afghanistan) and Africa, though conflict in the  former Yugoslavia and elsewhere in post-Cold War Europe significantly  increased the number of refugees in those regions.

It marks the transition from the massive rectilinear forms of fur�  niture in the Louis XIV style to the Rococo forms of Louis XV style. In reac�  tion against the pomposity of Louis XIV�s court, smaller, more intimate  rooms replaced formal state apartments and called for a more graceful  style. The delicately styled Regence furniture replaced heavy, carved orna�  mentation with flat, curving motifs, often foliage and bouquets framed by  flowing ribbons and bows. Walnut, rosewood, and mahogany supplied  rich but tasteful contrasts in veneering. Intricate tracery in brass and tor�  toiseshell marquetry on ebony was adapted to the new taste. The com�  mode and writing table were introduced during this period.</p><p>Regency style Style in the decorative arts and architecture produced  in England during the regency (1811-20) and reign (1820-30) of George  IV. Designers borrowed both structural and ornamental elements from  Greek and Roman antiquity. Egyptian motifs, inspired by Napoleon�s  Egyptian campaign of 1798, became part of the Regency fashion. A resur�  gence of a taste for chinoiserie is seen in imitation bamboo and in  �japanned� lacquerwork. The prince�s taste for French furniture popular�  ized pieces ornamented with brass marquetry in the French style. Orna�  mentation relied on rich contrasts of exotic wood veneers and application  of metal or painting rather than extensive carving.</p><p>Reger Vra-gor\, (Johann Baptist Joseph) Max(imilian) (b.</p><p>March 19, 1873, Brand, Bavaria, Ger.�d.

It was the administrative headquarters of the Northwest Territories  1882-1905, then it became the provincial capital. It was the headquarters  of the Royal Canadian Mounted Police until 1920. After World War II the  city expanded rapidly to become an important transportation, manufac�  turing, and distributing centre for a vast agricultural area. Local mineral  resources and fertile prairies support an economy based largely on oil,  natural gas, potash refining, and food processing.</p><p>regional development program Any government program  designed to encourage the industrial and economic development of  regions beset by joblessness or other economic hardship. Most industri�  alized countries have adopted some type of regional development pro�  gram since World War II. The most common method of encouraging  development is to offer grants, loans, and loan guarantees to companies  relocating or expanding in the region. France, for example, has offered  subsidies related to the amount of investment and the number of new jobs  created, as well as loans, interest subsidies, and free land sites. Tax incen�  tives are also used to encourage companies to invest in depressed areas.  In other programs, the government may offer low-cost housing for work�  ers and assistance in developing power, light, transportation, and sanita�  tion facilities. See also development bank.</p><p>regression In statistics, a process for determining a line or curve that  best represents the general trend of a data set. Linear regression results  in a line of best fit, for which the sum of the squares of the vertical dis�  tances between the proposed line and the points of the data set are mini�  mized (see least squares method). Other types of regression may be based  on higher-degree polynomial functions or exponential functions. A quadratic  regression, for example, uses a quadratic function (second-degree poly�  nomial function) to produce a parabola of best fit.</p><p>regressive tax Tax levied at a rate that decreases as its base increases.  Regressivity is considered undesirable because poorer people pay a  greater percentage of their income in tax than wealthier people. Consump�  tion TAXes and sales TAXes are usually considered regressive because of their  set rate structures. Tobacco, gasoline, and liquor sales taxes, all major  sources of tax revenue, are the most regressive taxes. In an effort to limit  regressivity, a number of U.S. states have exempted medicine and gro�  cery items from sales tax. Although the property tax is sometimes judged  regressive because poorer people spend a larger percentage of their  income on housing than wealthier people, property taxes are nonetheless  effective in redistributing wealth from higher to lower income groups.

Opposed to the high  taxes and corruption of the colonial government, the group sought vainly  to obtain reforms; it then refused to pay taxes, agitated against public  officials, and committed acts of violence. Gov. William Try on sent troops  to crush the insurrection at the Battle of Alamance (1771). The leaders  were hanged for treason, and many followers fled to Tennessee, where  they sided with the loyalists in the American Revolution.</p><p>regulatory agency Independent government commission charged by  the legislature with setting and enforcing standards for specific industries  in the private sector. The concept was invented by the U.S. government  in 1887, and regulatory agencies exist almost exclusively in the U.S. The  theory is that a commission of experts on the industry being regulated is  better equipped to regulate it than the legislature or executive departments.  Designed to operate with a minimum of executive or legislative supervi�  sion, agencies have executive, legislative, and judicial functions, and their  regulations have the force of law. Important regulatory agencies include  the Food and Drug Administration, OSHA, the Federal Communications  Commission, and the Securities and Exchange Commission.</p><p>Rehnquist \'ren-,kwist\, William H(ubbs) (b.

He received his law degree  from Stanford University and served as clerk to Supreme Court justice Rob�  ert Jackson. He later practiced law in Phoenix, Ariz. (1953-69), where he  became active in the conservative wing of the Republican Party. At the U.S.  Justice Department (1969-71), he opposed civil rights legislation and  advocated greatly enlarged police powers. He was nominated for the  Supreme Court by Pres. Richard Nixon in 1972. During the 1970s and into  the �80s, Rehnquist formed the anchor of the court�s conservative minority  bloc. His polished legal opinions and consistently conservative stance on  almost all legal issues led Pres. Ronald Reagan to appoint him chief justice  in 1986. Rehnquist dramatically reduced the court�s caseload and  improved its efficiency. With the support of other conservatives, he led the  court in curbing the ability of Congress to expand federal authority and in  curtailing affirmative action programs.

His early music explored the process of simultaneous repeated  patterns gradually slipping out of phase (�process music�). With Terry  Riley (b. 1935) and Philip Glass, he was among the most prominent of the  early �minimalists� of the 1970s. His early works include Drumming  (1971) and Music for 18 Musicians (1976); later works such as The Desert  Music (1983) and Different Trains (1988) show a considerably expanded  compositional vocabulary.</p><p>Reich \'rikV Wilhelm (b. March 24, 1897, Dobrzcynica, Galicia,  Austria-Hungary�d. Nov. 3, 1957, Lewisburg, Pa., U.S.) Austrian-U.S.  psychologist. Trained at the Berlin Psychoanalytic Institute, he joined the  faculty of the Vienna Psychoanalytic Institute in 1924. In The Function  of the Orgasm (1927), he argued that the failure to achieve orgasm could  produce neurosis. An advocate of sexual education and freedom as well  as of radical left-wing politics, he left Germany in 1933 and settled in the  U.S. in 1939. After breaking with the psychoanalytic movement in 1934,  he developed a pseudoscientific system called orgonomy. He conceived  of mental illness and some physical illnesses as deficiency of cosmic  energy (measured in units called �orgones�), which he treated by placing  the patient in a cabinet with reflective inner surfaces known as the orgone  box. Reich�s views brought him into conflict with U.S. authorities in the  early 1950s; he was convicted of contempt of court and died in prison.</p><p>Reichstag \'r!ks-,tak\ fire (Feb. 27, 1933) Burning of the German par�  liament building (Reichstag) in Berlin. Allegedly set by a Dutch commu�  nist, the fire was used by Adolf Hitler to turn public opinion against his  opponents, especially the communists. He enacted a decree suspending  constitutional protection of personal rights, which effectively began the  Nazi Party dictatorship. The fire was widely believed to have been set by  the Nazis themselves, while others have argued there was no proof of Nazi  complicity; it remains the subject of debate and research.</p><p>Reid, Thomas (b. April 26, 1710, Kincardineshire, Scot.�d. Oct. 7,  1796, Glasgow) Scottish philosopher. He served as a Presbyterian pastor  from 1737 to 1751. His lengthy studies of David Hume convinced him that  Hume�s skepticism was false, because it was incompatible with common  sense. According to Reid, both human behaviour and ordinary language  provide overwhelming evidence to support the reality of a material world  and the existence of an enduring self as the subject of continuously chang�  ing mental experience. His works include An Inquiry into the Human  Mind (1764), Essays on the Intellectual Powers of Man (1785), and Essays  on the Active Power of Man (1788).</p><p>Reign of Terror French La Terreur (1793-94) Period in the French  Revolution. It was established by the government on Sept. 5, 1793, to take  harsh measures against those suspected of being enemies of the Revolu�  tion (including nobles, priests, and hoarders). Controlled by the radical  Committee of Public Safety and Maximilien Robespierre, the Terror eliminated  enemies on the left (Jacques Hebert and his followers) and the right  (Georges Danton and the Indulgents). A law passed in June 1794 that sus�  pended a suspect�s right to public trial or legal defense caused the Ther-  midorian Reaction, and the Terror ended on July 27, 1794, with  Robespierre�s overthrow. About 300,000 suspects were arrested during the  period; about 17,000 were executed, and many others died in prison.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1604 I Reims &#x25BA; relation</p><p>Reims or Rheims \'remz,\ French \'re n s\ City (pop., 1999: 187,206),  northeastern France.

Belief in reincar�  nation is characteristic of Asian religions, especially Hinduism, Jainism,  Buddhism, and Sikhism. All hold to the doctrine of karma, the belief that  actions in this life will have their effect in the next. In Hinduism, a per�  son may be freed from the cycle of birth and rebirth only by reaching a  state of enlightenment. Likewise in Buddhism, discipline and meditation  may enable a seeker to reach nirvana and escape the wheel of birth and  rebirth. Manichaeism and Gnosticism accepted the concept of reincarnation,  as do such modern spiritual movements as Theosophy.</p><p>reindeer Any species of Arctic deer in the genus Rangifer (family  Cervidae), especially Old World species, some of which are domesticated.  New World species are usually called caribou.

He created and produced The Dick Van Dyke Show (1961-66), for  which he won several Emmy Awards. His novel Enter Laughing (1958)  was adapted as a play (1963) and a movie (1967). He directed film com�  edies such as Where�s Poppa (1970), Oh, God! (1977), and Fatal Instinct  (1993).

The rein�  forcing steel�rods, bars, or mesh�absorbs the tensile, shear, and some�  times the compressive stresses in a concrete structure. Plain concrete does  not easily withstand tensile and shear stresses caused by wind, earth�  quakes, vibrations, and other forces and is therefore unsuitable in most  structural applications. In reinforced concrete, the tensile strength of steel  and the compressive strength of concrete work together to allow the mem�  ber to sustain these stresses over considerable spans. The invention of  reinforced concrete in the 19th century revolutionized the construction  industry, and concrete became one of the world�s most common building  materials.</p><p>Reinhardt, Ad(olf Frederick) (b.

He employed several abstract  styles in the 1930s and �40s, but by the early 1950s he had restricted his  works to monochrome paintings incorporating symmetrically placed  squares and oblong shapes against backgrounds of similar colour, in which  drawing, line, brushwork, texture, light, and most other visual elements  were suppressed. He explained his style as a conscious search for an art  that would be entirely separate from life. He influenced the Minimalist  movement of the 1960s, more as a polemicist than as a painter.</p><p>Reinhardt, Django orig. Jean-Baptiste Reinhardt (b. Jan. 23,  1910, Liberchies, Belg.�d.

After studying drama in Vienna and acting in Salzburg,  he joined Otto Brahm�s company in Berlin in 1894. Reinhardt directed  his first play in 1902 and managed a small theatre from 1903. He had  directed more than 40 plays by 1905, when he became famous for his  creative staging of Shakespeare�s A Midsummer Night�s Dream. He  bought Berlin�s Deutsches Theater and remodeled it with the latest inno�  vations in scenic design and lighting. Known for the extravagant theat�  ricality and stunning visual effects of his productions, he won much praise  for his staging of the religious spectacle The Miracle (1911). In 1920 he  cofounded the Salzburg Festival, where he staged Jedermann (an adap�  tation of Everyman ) in the cathedral square. He left Germany in 1933 and  eventually settled in the U.S. A major influence on 20th-century drama,  he helped increase the creative authority of the director.</p><p>Reinsurance Treaty (June 18, 1887) Secret agreement between Ger�  many and Russia.

Onset is sudden, with high fever, which breaks within a week  with profuse sweating. Symptoms return about a week later. There may  be 2 to 10 relapses, usually decreasing in severity. Mortality usually  ranges from 0 to 6%, up to 30% in rare epidemics. Central nervous sys�  tem involvement causes various (usually mild) neurological symptoms.  The first microscopic organisms clearly associated with serious human  disease (1867-68), the spirochetes mutate repeatedly, changing their anti�  gens so that the host�s immunity no longer is effective, which produces  the relapses. Antibiotics can be effective, but inadequate therapy may  leave spirochetes alive in the brain, and they may reinvade the blood�  stream.</p><p>relation In logic, a relation R is defined as a set of ordered pairs, triples,  quadruples, and so on.

In general, a relation is any set of ordered n-tuples of  objects. Important properties of relations include symmetry, transitivity,  and reflexivity. Consider a two-place (or dyadic) relation R.

The description of a particular entity is provided by the set  of its attribute values, stored as one row or record of the table, called a  tuple. Similar items from different records can appear in a table column.  The relational approach supports queries that involve several tables by  providing automatic links across tables. Payroll data, for example, can be  stored in one table and personnel benefits data in another; complete infor�  mation on an employee can be obtained by joining the tables on employee  identification number. In more powerful relational data models, entries  can be programs, text, unstructured data in the form of binary large objects  (BLOBs), or any other format the user requires. The relational approach  is currently the most popular model for database management system.

In classical physics, it was  assumed that all observers anywhere in the universe would obtain identical  measurements of space and time intervals. According to relativity theory,  this is not so; all measurements depend on the relative motions of the  observer and the observed. There are two distinct theories of relativity, both  proposed by Albert Einstein. The special theory of relativity (1905) devel�  oped from Einstein�s acceptance that the speed of light is the same in all  reference frames, irrespective of their relative motion. It deals with non�  accelerating reference frames, and is concerned primarily with electric and  magnetic phenomena and their propagation in space and time. The general  theory (1916) was developed primarily to deal with gravitation and  involves accelerating reference frames. Both theories are major milestones  in the history of modern physics.

Bas-  reliefs (�low reliefs�), in which the  design projects only slightly, were  common on the walls of stone build�  ings in ancient Egypt, Assyria, and  elsewhere in the Middle East. High  reliefs, in which the forms project at  least half or more of their natural cir�  cumference, were first employed by  the ancient Greeks. Italian Renais�  sance sculptors combined high and  low relief in strikingly illusionistic  compositions, as in Lorenzo Ghiber�  ti�s bronze doors in Florence.</p><p>Baroque sculptors continued these</p><p>experiments, often on a larger scale (e.g., Alessandro Algardi�s Meeting  of Attila and Pope Leo, 1646-53).

A distinction may be drawn  between relief targeting upheavals and natural disasters and relief of  chronic social conditions, now usually referred to as welfare. In 17th-  century China the government maintained ever-normal granaries for use  in the event of famine. Through the 19th century, disaster relief in Europe  consisted largely of emergency grants of food, clothing, and medical care  through hastily organized local committees. In the 20th century, disaster  relief became one of the chief activities of the International Red Cross and  other international agencies. Assistance to the needy from public funds  has traditionally been strictly limited; in England, the Poor Law Reform  Act of 1834 required people able to work to enter a workhouse in order  to receive public assistance. The U.S. government responded to the Great  Depression with the New Deal, which emphasized work relief programs  such as the Works Progress Administration. In the later 20th century, the  work requirement was abandoned in most countries, and the needy  received direct cash payments, though in the U.S. the movement for wel�  fare reform resulted in the passage in 1996 of �workfare� laws cutting off  relief for most able-bodied welfare recipients who failed to find a job or  perform community service.</p><p>relief printing See letterpress printing</p><p>religion Relation of human beings to God or the gods or to whatever  they consider sacred or, in some cases, merely supernatural. Archaeologi�  cal evidence suggests that religious beliefs have existed since the first  human communities. They are generally shared by a community, and they  express the communal culture and values through myth, doctrine, and  ritual. Worship is probably the most basic element of religion, but moral  conduct, right belief, and participation in religious institutions also con�  stitute elements of the religious life. Religions attempt to answer basic  questions intrinsic to the human condition (Why do we suffer? Why is  there evil in the world? What happens to us when we die?) through the  relationship to the sacred or supernatural or (e.g., in the case of Buddhism)  through perception of the true nature of reality. Broadly speaking, some  religions (e.g., Judaism, Christianity, and Islam) are outwardly focused, and  others (e.g.. Jainism, Buddhism) are inwardly focused.</p><p>religion, philosophy of Branch of philosophy that studies key meta�  physical and epistemological concepts, principles, and problems of reli�  gion.

The spread of French Calvinism persuaded the French ruler  Catherine de Medicis to show more tolerance for the Huguenots, which  angered the powerful Catholic de Guise family. Its partisans massacred a  Huguenot congregation at Vassy (1562), causing an uprising in the prov�  inces. Many inconclusive skirmishes followed, and compromises were  reached in 1563, 1568, and 1570. After the murder of the Huguenot leader  Gaspard II de Cougny in the Massacre of Saint Bartholomew's Day (1572),  the civil war resumed. A peace compromise in 1576 allowed the Hugue�  nots freedom of worship. An uneasy peace existed until 1584, when the  Huguenot leader Henry of Navarra (later Henry IV) became heir to the  French throne. This led to the War of the Three Henrys and later brought  Spain to the aid the Catholics. The wars ended with Henry�s embrace of  Catholicism and the religious toleration of the Huguenots guaranteed by  the Edict of Nantes (1598).</p><p>Religious Science Movement founded in the U.S. by Ernest Holmes  (1887-1960).

Drafted into the German army at age  18, he served in World War I and was wounded several times. He is chiefly  remembered for All Quiet on the Western Front (1929), a brutally real�  istic account of the daily routine of ordinary soldiers and perhaps the  best-known and most representative novel about that war. He moved to  the U.S. in 1939 and became a U.S. citizen but settled in Switzerland after  World War II.

Oct. 4, 1669, Amsterdam) Dutch painter and etcher. The  son of a prosperous miller in Leiden, he was apprenticed to masters there  and in Amsterdam. His early works show the spotlight effects of light and  shadow that were to dominate his later works. After moving to Amsterdam  in 1631, he quickly became the city�s most fashionable portrait painter, and  in 1632 he was commissioned to paint the celebrated Anatomy Lesson of  Dr. Nicolaes Tulp. Yearning for recognition as a biblical and mythological  painter, in 1635 he produced his Sacrifice of Isaac and in 1636 the uncon�  ventional masterpiece Danae. In 1634 he married Saskia van Uylenburgh,  a woman of property, and he painted many tender pictures of her until 1642,  when Saskia died. That same year he completed his largest painting, the  extraordinary but controversial The Militia Company of Captain Frans  Banning Cocq (known as The Night Watch), which was a watershed in his  life and art. His portrait commissions thereafter declined and he turned  increasingly to etchings and biblical subjects. His Christ at Emmaus (1648)  exemplifies the quiet dignity and vulnerability of his later spirituality. In  1656, after transferring most of his property to his son, he applied for bank�  ruptcy. In his last decade he treated biblical subjects like portraits, and also  did a wealth of self-portraits; many of these paintings evoke a timeless  world of quiet, deep emotion. His paintings are characterized by luxuriant  brush work, rich colour, and a mastery of chiaroscuro. The silent human fig�  ure, Rembrandt�s central subject, contributes to the sense of a shared dia�  logue between viewer and picture, the foundation of Rembrandt�s  greatness and of his popularity today.</p><p>Remington, Eliphalet (b.

The Renaissance brought renewed interest in Clas�  sical learning and values to Italy and subsequently the rest of western and  central Europe from the late 13th to the early 17th century. Attracted by  the values and rhetorical eloquence of ancient writers, figures such as  Petrarch, Giovanni Boccaccio, and Lorenzo Valla rejected medieval Scho�  lasticism in favour of human-centred forms of philosophy and literature.  In northern Europe, Desiderius Erasmus cultivated Christian humanism, and  writers such as Francois Rabelais and William Shakespeare produced works  that emphasized the intricacies of human character. Inspired by ancient  Greece and Rome, Renaissance painters and sculptors took the visible  world for their subject and practiced according to mathematical principles  of balance, harmony, and perspective. The new aesthetic found expres�  sion in the works of Italian artists such as Leonardo da Vinci, Sandro Bot�  ticelli, Raphael, Titian, and Michelangelo, and the Italian city of Florence  became the centre of Renaissance art. The term has also been applied to  cultural revivals in England in the 8th century, the Frankish kingdoms in  the 9th century, and Europe in the 12th century. See also Renaissance  ARCHITECTURE.</p><p>Renaissance architecture Style of architecture, reflecting the  rebirth of Classical culture, that originated in Florence in the early 15th  century and spread throughout Europe, replacing the medieval Gothic  style. There was a revival of ancient Roman forms, including the column  and round arch, the tunnel vault, and the dome. The basic design element  was the order. Knowledge of Classical architecture came from the ruins of  ancient buildings and the writings of Vitruvius. As in the Classical period,  proportion was the most important factor of beauty; Renaissance archi�  tects found a harmony between human proportions and buildings. This  concern for proportion resulted in clear, easily comprehended space and  mass, which distinguishes the Renaissance style from the more complex  Gothic. Filippo Brunelleschi is considered the first Renaissance architect.  Leon Battista Alberti�s Ten Books on Architecture, inspired by Vitruvius,  became a bible of Renaissance architecture. From Florence the early  Renaissance style spread through Italy. Donato Bramante�s move to Rome  ushered in the High Renaissance (c. 1500-20). Mannerism, the style of  the Late Renaissance (1520-1600), was characterized by sophistication,  complexity, and novelty rather than the harmony, clarity, and repose of  the High Renaissance. The Late Renaissance also saw much architectural  theorizing, with Sebastiano Serlio (1475-1554), Giacomo da Vignola  (1507-1573), and Andrea Palladio publishing influential books.</p><p>renal cell carcinoma or hypernephroma Malignant tumour of  the cells that cover and line the kidney.

He trained for the  priesthood but left the Catholic  church in 1845, feeling that its teach�  ings were incompatible with the  findings of historical criticism,  though he retained a quasi-Christian  faith in God. His five-volume His�  tory of the Origins of Christianity  (1863-80) includes his Life of Jesus  (1863); an attempt to reconstruct the  mind of Jesus as a wholly human  person, it was virulently denounced  by the church but widely read by the  general public. His later works  include the series History of the  People of Israel (1888-96).</p><p>renga \'req-,ga\ Japanese linked-  verse poetry in which two or more  poets supply alternating sections of a  poem. The form began with the composition of a traditional five-line poem  (tanka) by two people. A popular pastime from ancient times, even in  remote rural areas, it developed fully in the 15th century. Composition  spread to court poets, who drew up �codes� to establish renga as an art.  An example of renga is the melancholy Minase sangin hyakuin (1488),  composed by Iio Sogi, Shohaku, and Socho. Later the initial verse ( hokku )  of a renga developed into the haiku form.</p><p>Reni \'ra-ne\, Guido (b. Nov. 4, 1575, Bologna, Papal States�d. Aug.  18, 1642, Bologna) Italian painter. Apprenticed to the Flemish painter  Denis Calvaert at 10, he was later influenced by the novel naturalism of  the Carracci family of his native Bologna, the frescoes of Raphael, and  ancient Greco-Roman sculpture. He executed many important commis�  sions in Rome, including the celebrated ceiling fresco Aurora (1613-14).  In his religious and mythological works, he tempered Baroque exuber�  ance and complexity with Classical restraint, tender emotion, and delicate  colouring. Until John Ruskin scorned him in the 19th century, he was  highly regarded; his status as one of the great painters of the 17th cen�  tury has since been reestablished.</p><p>Renner, Karl (b.

A lawyer, he served in the  Reichsrat (lower house) from 1907. He became the first chancellor of the  new Austrian republic in 1918 but was unable to prevent territorial losses  at the end of World War I. In the 1920s he led the right wing of the Social  Democratic Party and in 1938 favoured the Anschluss with Germany. In  1945 he worked to reestablish Austrian home rule and was elected presi�  dent of the republic. He wrote numerous works on government and law.</p><p>Rennes Vren\ City (pop., 1999: 206,229), western France. Located at  the confluence of the Ille and Vilaine rivers, Rennes was once under  Roman occupation. It was the capital of Brittany in the Middle Ages and  a rival of Nantes. It was the seat of the Brittany parliament from 1561 to  1675. Rennes was almost completely destroyed by fire in 1720 and was  rebuilt. It was bombed and partly destroyed in World War II. It is a com�  mercial and industrial city, producing railway equipment, automobiles,  and chemicals. It is also the cultural centre of Brittany.</p><p>Rennie, John (b.

He worked on extensive drainage projects in  the Lincolnshire fens; built the London and East India docks on the</p><p>Thames; improved naval dockyards at Plymouth, Portsmouth, Chatham,  and Sheerness; and began the great breakwater that shelters Plymouth  Sound.</p><p>Reno Yre-no\ City (pop., 2000: 180,480), western Nevada, U.S. It is  located on the Truckee River, near the California border, Lake Tahoe, and  the Sierra Nevada foothills. Until 1900 it was primarily a distribution  point, but, after several well-known people were granted divorces or were  quickly married there under liberal state laws, it became famous as a busy  divorce and marriage centre. It is also a year-round vacation centre. When  gambling was legalized in Nevada in 1931, Reno began to attract tour�  ists to its many casinos.</p><p>Renoir, Jean (b. Sept. 15, 1894, Paris, France�d. Feb. 12, 1979, Los  Angeles, Calif., U.S.) French film  director. The son of Pierre-Auguste  Renoir, he discovered a passion for  the cinema while recovering from  wounds suffered in World War I. He  directed his first film, La Fille de  Teau, in 1924. His films, in both  silent and later eras, were noted for  their deep appreciation for the unpre�  dictability of human character. He  cowrote the screenplays for many of  his films, including Boudu Saved  from Drowning (1932), Madame  Bovary (1934), The Crime of Mon�  sieur Lange (1936), and La Bete  humaine (1938) as well as his two  masterpieces, Grand Illusion (1937)  and The Rules of the Game (1939).</p><p>He lived in the U.S. (1940-51),  where he directed The Southerner  (1945), The Diary of a Chamber�  maid (1946), and The River (1951).</p><p>Renoir \r9n-'war\, Pierre-Auguste (b. Feb. 25, 1841, Limoges,  France�d. Dec. 3, 1919, Cagnes) French painter. His father, a tailor in  Limoges, moved with his large family to Paris in 1844. Renoir began work�  ing as a decorator of porcelain at 13 and studied painting at night. He  formed a close friendship with his fellow student Claude Monet and became  a leading member of the Paris Impressionists. His early works were typically  Impressionist snapshots of real life, full of sparkling colour and light. By  using small, multicoloured strokes, Renoir evoked the vibration of the  atmosphere, the sparkling effect of foliage, and especially the luminosity of  a young woman�s skin in the outdoors. Because of his fascination with the  human figure, he was distinctive among the others, who were more inter�  ested in landscape. Among his early masterpieces are Le Moulin de la Gal-  ette (1876) and The Luncheon of the Boating Party (1881). A visit to Italy  (1881-82) introduced him to Raphael and the expressive force of clear line  and smooth painting, and by the mid 1880s he had broken with Impres�  sionism to employ a more disciplined, formal technique. In works such as  Bathers (1884-87), he emphasized volume, form, contours, and line. In his  later works, he departed from the strict rules of Classicism to paint colour�  ful still lifes, portraits, nudes, and landscapes of southern France, where he  settled in 1907. Rheumatism confined him to a wheelchair by 1912 but he  never ceased to paint, even though often with his brush attached to his  hand. The filmmaker Jean Renoir was his son.</p><p>rent In common usage, payment made in return for the right to use prop�  erty belonging to another. In classical economics, rent was the income  gained from cultivated or improved land after the deduction of all pro�  duction costs. In modern economic usage, rent is the difference between  the total return to a factor of production (land, labour, capital) and its sup�  ply price, the minimum amount necessary to attain its services. Rent plus  opportunity cost make up the total income paid to a productive resource.  Efforts made by a resource owner to obtain monopoly profit is considered  rent-seeking behaviour.</p><p>Renta, Oscar de la See Oscar de la Renta</p><p>Reorganized Church of Jesus Christ of Latter Day Saints</p><p>See Community of Christ</p><p>reovirus \ l re-o-'vl-ros\ Any of a small group of animal and plant viRUSes  that appear spheroidal and contain a core of RNA.

Repertory companies, or stock companies, originally presented a differ�  ent play each night of the week while preparing and rehearsing new plays.  The system evolved to the current practice of presenting a series of short,  continuous runs of each play.</p><p>Repin \'rya-pyin,\ English \'ra-pin\, Ilya (Yefimovich) (b.

After training with a provincial icon painter and at the St. Peters�  burg Academy of Fine Arts, he visited France and Italy on an academy  scholarship. On his return he began painting subjects from Russian his�  tory. In 1873 he achieved international fame with Volga Boatmen, a grim,  powerful image that became the model for Soviet Socialist Realism. Among  his best-known works is Ivan the Terrible and His Son Ivan (1895), depict�  ing Ivan�s murder of his son. He also painted vigorous portraits (includ�  ing Leo Tolstoy and Modest Mussorgsky). In 1894 he became professor of  historical painting at the St. Petersburg Academy.</p><p>replacement deposit In geology, a mineral deposit formed by chemi�  cal processes that dissolve the original rock and deposit a new assem�  blage of minerals in its place. See also metasomatic replacement.</p><p>representation In politics, a method or process of enabling a con�  stituency to influence legislation and government policy through deputies  chosen by it. The rationale of representative government is that in large  modern countries the people cannot all assemble, as they did in the mar�  ketplace of democratic Athens. If the public is to participate in govern�  ment, citizens must select a small number from among themselves to act  for them. Political parties have come to act as intermediaries between  citizens and their representatives by helping to formulate systematically  citizens� demands. Arguments persist about the proper role of represen�  tatives; some theories suggest that they should act as delegates carrying  out the instructions of the public, whereas others argue that they should  serve as free agents, acting in accordance with their best ability and under�  standing.

The act of 1918 gave the vote to</p><p>&#x25A0; all men over 21 and all women over 30, which tripled the electorate. The</p><p>act of 1928 extended the franchise to women aged 21-30.

The validity of human  knowledge is thus called into question because of the need to show that  such images accurately correspond to the external objects. The doctrine,  still current in certain philosophical circles, has roots in Cartesianism, the  empiricism of John Locke and David Hume, and the idealism of Immanuel Kant.</p><p>repression In metabolism, a control mechanism by which a protein  molecule, called a repressor, prevents the synthesis of an enzyme by bind�  ing to (and thus hindering the action of) the DNA that controls the  enzyme�s synthesis. Though the process has been studied mainly in micro�  organisms, it is believed to occur in a similar way in higher organisms.  See also inhibition.</p><p>repression In psychoanalytic theory, the exclusion of distressing  memories, thoughts, or feelings from the conscious mind. Often involv�  ing sexual or aggressive urges or painful childhood memories, these  unwanted mental contents are pushed into the unconscious mind. Repres�  sion is thought to give rise to anxiety and to neurotic symptoms, which</p><p>begin when a forbidden drive or impulse threatens to enter the conscious  mind. Psychoanalysis seeks to uncover repressed memories and feelings  through free association as well as to examine the repressed wishes  released in dreams. See also unconscious.</p><p>reproduction Process by which organisms replicate themselves, assur�  ing continuation of their species. The two basic forms are asexual and  sexual. Asexual reproduction (e.g., fission, spore formation, regeneration,  and vegetative reproduction) produces an offspring genetically identical  to its single parent. Sexual reproduction produces a new individual  through the union of special sex cells (gametes), usually from different  parents. Gametes result from meiosis. Gamete union results in a zygote,  the first cell of a new organism. Sexual reproduction ensures that each  offspring is genetically unique (except in cases of multiple offspring  derived from divisions of one zygote). Most animals, including all ver�  tebrates, reproduce sexually.</p><p>reproductive behaviour In animals, any activity directed toward  perpetuation of a species. Sexual reproduction, the most common mode,  occurs when a female�s egg is fertilized by a male�s sperm. The resulting  unique combination of genes produces genetic variety that contributes to  a species� adaptability. The stages of approach, identification, and copu�  lation are well developed to avoid predators and the wastage of eggs and  sperm. Most one-celled and some more-complex organisms reproduce  asexually. See also courtship behaviour.</p><p>reproductive system, human Organ system by which humans  reproduce. In females, the ovaries sit near the openings of the fallopian  tubes, which carry eggs from the ovaries to the uterus. The cervix extends  from the lower end of the uterus into the vagina, whose opening, as well  as that of the urethra (see urinary system), is covered by four folds of skin  (the labia); the clitoris, a small erectile organ, is located where the labia  join in front. The activity of the ovaries and uterus goes through a monthly  cycle of changes (see menstruation) throughout the reproductive years  except during pregnancy and nursing. In males, the testes lie in a sac of  skin (the scrotum). A long duct (the vas deferens) leads from each testis  and carries sperm to the ejaculatory ducts in the prostate gland; these join  the urethra, which continues through the penis. In the urethra, sperm mixes  with secretions from the seminal vesicles, prostate gland, and Cowper  gland to form semen. In early embryos, the reproductive systems are unde�  termined. By birth the organs appropriate to each sex have typically devel�  oped but are not functioning. They continue to grow, and at puberty their  activity increases and maturation occurs, enabling sexual reproduction.  See illustration on opposite page.</p><p>reptile Any of the approximately 6,000 species of the class Reptilia, air-  breathing vertebrates that have internal fertilization and a scaly body and  are cold-blooded. Most species have short legs (or none) and have long  tails, and most lay eggs. Living reptiles include the scaly reptiles (snakes  and lizards; order Squamata), the crocodiles (Crocodilia), the turtles (Che-  lonia), and the unique tuatara (Rhynchocephalia). Being cold-blooded,  reptiles are not found in very cold regions, and in regions with cold win�  ters they usually hibernate. They range in size from geckos that measure  about 1 in. (3 cm) long to the python, which grows to 30 ft (9 m); the  largest turtle, the marine leatherback, weighs about 1,500 lbs (680 kg).  Extinct reptiles include the dinosaurs, the pterosaurs, and the dolphinlike  ichthyosaurs.</p><p>republic Form of government in which a state is ruled by representa�  tives elected by its populace. The term was originally applied to a form  of government in which the leader is periodically appointed under a con�  stitution; it was contrasted with governments in which leadership is  hereditary. A republic may also be distinguished from direct democracy,  though modern representative democracies are by and large republics.</p><p>Republican, Radical See Radical Republican</p><p>Republican Party or GOP (Grand Old Party) One of two major  U.S. political parties.

In a male, the scrotum, a pouch of skin,  is divided into two sacs, each containing a testis and its associated epididymis.  Tubules within the testes contain sperm cells at different stages of development. As  sperm leaves the testes, it passes into the epididymis, a highly coiled tube that  serves as a reservoir for sperm. The vas deferens, a duct leading out from the epid�  idymis, joins with the duct of the seminal vesicles as it passes through the prostate  gland to form a single tube (ejaculatory duct) that opens into the urethra, the tube  that conveys both sperm and urine out through the penis. In a menstruating  woman, a follicle containing an egg matures each month in either of two ovaries.  Ovulation occurs as the mature follicle ruptures and releases an egg, which is  drawn into the ovary's associated fallopian (uterine) tube, which contains a fringe  of fingerlike projections (fimbriae). Fertilization usually occurs in the fallopian tube  as the egg travels to the uterus. Successful implantation of a fertilized egg in the  uterus results in development of an embryo. The vagina, a muscular tube that leads  to the uterus, allows sperm to pass into the uterus and serves as a passageway for  the fetus during childbirth.</p><p>� MERRIAM-WEBSTER INC.</p><p>petitive in the South for more than a century after the war. Republican  candidates won 14 of 18 presidential elections between 1860 and 1932,  through support from an alliance of Northern and Midwestern farmers and  big-business interests. In 1912 the party split between a progressive wing  led by Theodore Roosevelt and a conservative wing led by Pres. William  Howard Taft; the rift enabled the Democratic candidate, Woodrow Wil�  son, to win that year�s election. The Republican Party�s inability to  counter the impact of the Great Depression led to its ouster from power in  1933; in 1953 the presidency of Dwight D. Eisenhower brought a moder�  ate wing of the party to prominence. The party�s platform remained con�  servative, emphasizing anticommunism, reduced government regulation</p><p>of the economy, and lower taxes; many members also opposed civil rights  legislation. In the 1950s the GOP gained new support from middle-class  suburbanites and white Southerners disturbed by the integrationist poli�  cies of the national Democratic Party. Richard Nixon, who narrowly lost  the 1960 presidential race, won narrowly in 1968 and by a landslide in  1972, but he was forced to resign in 1974 as a result of the Watergate  scandal. Ronald Reagan, who had assumed the leadership of the conser�  vative wing of the Republican Party after Barry Goldwater�s defeat in the  presidential election of 1964, won the presidency in 1980 and 1984; he  introduced deep tax cuts and launched a massive buildup of U.S. military  forces. Reagan�s vice president, George Bush, was elected in 1988 and  enjoyed enormous popularity after success in the First Persian Gulf War,  but an anemic economy led to his defeat in 1992 by Democrat Bill Clin�  ton. The defeat was offset in 1994, when the Republicans regained con�  trol of the House of Representatives for the first time in 40 years. In 2000  George W. Bush narrowly won the presidency in one of the closest and  most controversial elections in U.S. history. In 2004 he won reelection.

Such measures have been applied  to a limited array of goods, including pharmaceuticals, books, photo�  graphic supplies, and liquor. Resale price maintenance first began to be  employed in the 1880s, reflecting the success of brand promotion and the  resulting increase in competition among retailers. It became especially  common in the U.S. but declined after World War II. It is prohibited in  some countries.

Applied research directs the results of basic research toward the needs of  a specific industry and results in the development of new or modified  products or processes. In addition to carrying out basic and applied  research and developing models, R&amp;D staff may evaluate the efficiency  and cost of the product.</p><p>resin Vre-z 3 n\ Any natural or synthetic organic compound consisting of  a noncrystalline (amorphous) solid or viscous liquid substance or mix�  ture. Natural resins are usually transparent or translucent yellow to brown  and can melt and burn. Most are exuded from trees, especially pines and  firs (see conifer), when the bark is injured or stripped. The fluid secretion  usually dries out and hardens into a material that can be worked. Natural  resins have been used in perfumes and medicines (e.g., balsams), in paints  and varnishes (e.g., turpentine and shellac, the latter derived from the  secretion of an insect), and in decorative ware (e.g., amber, Oriental lac�  quer). Synthetic resins are all plastics; the term resin, though still used in  the modem industry, dates from the years when synthetics began to  replace natural resins. Thermoplastic resins are plastics such as polyeth�  ylene that can be shaped repeatedly on reheating, whereas thermosetting  resins are plastics such as epoxy that set permanently and cannot be  reshaped.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1610 I resistance &#x25BA; Reston</p><p>resistance Opposition that a material or electrical circuit offers to the  flow of electric current.

The groups included  civilians who worked secretly against the occupation and armed bands of  partisans or guerrilla fighters. Resistance activities ranged from assisting  the escape of Jews and Allied airmen shot down over enemy territory to  committing sabotage, ambushing German patrols, and sending intelligence  information to the Allies. Resistance groups were not always unified; in  some countries, rival groups divided along communist and noncommunist  lines. However, in France the clandestine National Council of the Resis�  tance coordinated all French groups, which gave support to the Normandy  Campaign and participated in the August 1944 uprising that helped liberate  Paris.

The amount of air inhaled and exhaled in an aver�  age human breath (tidal volume) is about one-eighth the amount that can  be inhaled after exhaling as much as possible (vital capacity). Nerve cen�  tres in the brain regulate the movements of muscles of respiration (dia�  phragm and chest wall muscles). Blood in the pulmonary circulation brings  carbon dioxide from the tissues to be exhaled and takes up oxygen from  the air in the pulmonary alveoli to carry it to the heart and the rest of the  body. Because the body stores almost no oxygen, interruption of  respiration�by asphyxiation, drowning, or chest muscle paralysis �for  more than a few minutes can cause death. Disorders affecting respiration  include allergy, asthma, bronchitis, emphysema, pneumonia, and tuberculosis.  See also respiratory system; respiratory therapy.</p><p>respiratory distress syndrome or hyaline membrane dis�  ease Common complication in newborns, especially after premature birth.  Symptoms include very laboured breathing, bluish skin tinge, and low  blood oxygen levels. Insufficient surfactant in the pulmonary alveoli raises  surface tension, hampering lung expansion.

In humans,  the diaphragm and, to a lesser extent, the muscles between the ribs gen�  erate a pumping action, moving air in and out of the lungs through a sys�  tem of pipes (conducting airways), divided into upper and lower airway  systems. The upper airway system comprises the nasal cavity (see nose),  siNUSes, and pharynx; the lower airway system consists of the larynx, tra�  chea, bronchi, bronchioles, and alveolar ducts (see pulmonary alveolus).  The blood and cardiovascular system can be considered elements of a  working respiratory system. See also thoracic cavity. See illustration on  opposite page.</p><p>respiratory therapy Medical profession concerned with assisting the  respiratory function of individuals who have severe lung disorders. Prac�  tices include suctioning to clear secretions from the airway, use of aero�  sol mists (sometimes medicated) or gases to ease breathing, and tilting  the body and chest percussion to promote drainage. A respiratory thera�  pist also manages mechanical ventilation, a process in which a machine  generates a controlled flow of a gas mixture into the airway of a patient  who cannot breathe efficiently.</p><p>restaurant Establishment where refreshments or meals are served to  paying guests. Though inns and taverns served simple fare to travelers for  centuries, the first modern restaurant where guests could order from a var�  ied menu is thought to have belonged to A. Boulanger, a soup vendor who  opened his business in Paris in 1765. The sign above his door advertised  restoratives, or restaurants, referring to his soups and broths. By 1804 Paris  had more than 500 restaurants, and France soon became internationally  famous for its cuisine. Other European restaurants include the Italian trat-  torie, taverns featuring local specialties; the German Weinstuben, informal  restaurants with a large wine selection; the Spanish tapas bars, which serve  a wide variety of appetizers; and the public houses of England. Asian res�  taurants include the Japanese sushi bars and teahouses serving formal Kai-  seki cuisine as well as the noodle shops of China. Most U.S. restaurant  innovations have revolved around speed. The cafeteria originated in San  Francisco during the 1849 gold rush; cafeterias feature self-service and  offer a variety of foods displayed on counters. The U.S. also pioneered fast-  food restaurants such as White Castle (founded 1921) and McDonald�s (see  Ray Kroc), usually operated as chains and offering limited menus.</p><p>Reston, James (Barrett) (b. Nov. 3, 1909, Clydebank, Dumbarton�  shire, Scot.�d. Dec. 6, 1995, Washington, D.C., U.S.) Scottish-born U.S.  columnist and editor. His family moved to the U.S. when he was 10 years  old. He was a sportswriter before joining The New York Times in 1939,  where he worked as a reporter, a nationally syndicated columnist, Wash�  ington bureau chief (1953-64), executive editor (1968-69), and vice  president (1969-74) before retiring in 1989. One of the most influential  U.S. journalists, he had unrivaled personal access to U.S. presidents and  world leaders and was often the first to break major stories. He won two  Pulitzer Prizes (1945, 1957), helped create the first Op-Ed page (1970; a  forum for columnists� opinion pieces), and recruited and trained many  talented young journalists.</p><p>1922, Vannes, France) French film</p><p>Resnais</p><p>COURTESY OF THE FRENCH FILM OFFICE, NEW YORK</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Restoration &#x25BA; retriever I 1611</p><p>tertiary ^  bronchus</p><p>upper or</p><p>-left</p><p>primary or  principal  bronchus</p><p>secondary</p><p>bronchus</p><p>nasal turbinate</p><p>epiglottis  pharynx -</p><p>nasal cavity  "vestibule of the nose</p><p>�-oral cavity</p><p>diaphragm</p><p>terminal bronchiole</p><p>larynx</p><p>trachea</p><p>superior lobe</p><p>horizontal</p><p>fissure</p><p>lower</p><p>oblique</p><p>fissure</p><p>inferior</p><p>lobe</p><p>bronchiole</p><p>respiratory</p><p>bronchiole</p><p>a veo us</p><p>alveolar duct</p><p>a veo ar sac</p><p>As air enters the nasal cavity through the nostrils, it is warmed and moistened by  mucous membranes of the nasal turbinates before entering the pharynx. Stiff hairs  lining the vestibule inside the nostrils help filter the entering air. The air-filled sinuses  adjacent to the nasal cavity produce mucus. The larynx connects the pharynx with  the trachea or windpipe. The cartilaginous epiglottis prevents food from entering  the larynx during swallowing. A left and right primary bronchus supply each lung  with air from the trachea. They divide into smaller secondary and tertiary bronchi;  the smallest divisions, bronchioles, lead to the cup-shaped, thin-walled alveoli,  which occur in clusters (alveolar sacs). Oxygen and carbon dioxide are exchanged  between the alveoli and surrounding capillaries. Oblique fissures or grooves of  each lung separate the upper lobe from the lower lobe. The horizontal, or trans�  verse, fissure of the right lung forms a middle lobe. Movement of the diaphragm  along with the ribs and rib muscles causes expansion and contraction of the lungs  during breathing.</p><p>� MERRIAM-WEBSTER INC.</p><p>Restoration Restoration of the monarchy in England in 1660. It marked  the return of Charles II as king (1660-85) following the period of Oliver  Cromwell�s Commonwealth. The bishops were restored to Parliament,  which established a strict Anglican orthodoxy. The period, which also  included the reign of James II (1685-88), was marked by an expansion in  colonial trade, the Anglo-Dutch Wars, and a revival of drama and litera�  ture (see Restoration literature).</p><p>Restoration literature English literature written after the Restoration  of the monarchy in 1660 following the period of the Commonwealth. Some  literary historians equate its era with the reign of Charles II (1660-85),  while others add the reign of James II (1685-88). Many typical modern lit�  erary forms (e.g., the novel, biography, history, travel writing, and journal�  ism) began to develop with sureness during the Restoration period.  Pamphlets and poetry (notably that of John Dryden) flourished, but the age  is chiefly remembered for its glittering, critical, and often bawdy comedies  of manners by such playwrights as George Etherege, Thomas Shadwell, Wil�  liam Wycherly, John Vanbrugh, William Congreve, and George Farquhar.</p><p>restraint of trade Preventing of free competition in business by some  action or condition such as price-fixing or the creation of a monopoly. The  U.S. has a long-standing policy of maintaining competition among busi�  ness enterprises through antitrust laws, the best-known of which, the Sher�  man Antitrust Act of 1890, declared illegal �every contract,  combination...or conspiracy in restraint of trade or commerce.�</p><p>restriction enzyme Protein (more specifically, an endonuclease) pro�  duced by bacteria that cleaves DNA at specific sites along its length.</p><p>Thousands have been found, from many different bacteria; each recog�  nizes a specific nucleotide sequence. In the living bacterial cell, these  enzymes destroy the DNA of certain invading viRUSes (bacteriophages), thus  placing a �restriction� on the number of viral strains that can cause infec�  tion; the bacterium�s own DNA is protected from cleavage by methyl  (�CH 3 ) groups, which are added by enzymes at the recognition sites to  mask them. In the laboratory, restriction enzymes allow researchers to  isolate DNA fragments of interest, such as those that contain genes, and  to recombine them with other DNA molecules; for this reason they have  become very powerful tools of recombinant DNA biotechnology (see  DNA RECOMBINATION).</p><p>restrictive covenant In property law, an agreement acknowledged in  a deed or lease that restricts the free use or occupancy of property, such  as by forbidding commercial use or certain types of structures. The restric�  tive covenant is as old as the law of property, being well-established in  Roman law. The term is also used in business law to refer to an agree�  ment whereby one party promises not to engage in the same business or  a similar business in a particular area for a period of time.</p><p>retailing Selling of merchandise directly to the consumer. Retailing  began several thousand years ago with peddlers hawking their wares at  the earliest marketplaces. It is extremely competitive, and the failure rate  of retail establishments is relatively high. Price is the most important arena  of competition, but other factors include convenience of location, selec�  tion and display of merchandise, attractiveness of the establishment, and  reputation. The diversity of retailing is evident in the many forms it now  takes, including vending machines, door-to-door and telephone sales, direct-  mail marketing, the Internet, discount houses, specialty stores, department  stores, supermarkets, and consumer cooperatives.</p><p>retaining wall or revetment Wall constructed to hold in place a  mass of earth or prevent the erosion of an embankment. It may also be  battered, with the face inclined toward the load it is bearing. The most  basic type of reinforced retaining wall is the massive concrete gravity  wall, which is prevented from falling over by the sheer weight and vol�  ume of its mass. A cantilever (L-shaped) retaining wall resists overturn�  ing by means of cantilever footings, spread footings (see foundation)  shaped to resist overturning and sliding.</p><p>reticuloendothelial Vre-.tik-yo-lo-.en-do-'the-le-olN system or  macrophage \ , mak-r9- 1 faj\ system or mononuclear phago�  cyte system Part of the body�s defenses, consisting of a class of cells  widely distributed in the body. Reticuloendothelial cells filter out and  destroy bacteria, viRUSes, and foreign substances and destroy worn-out or  abnormal cells and tissues. Precursor cells in bone marrow develop into  monocytes (see leukocyte), which are released into the bloodstream. Most  enter body tissues, developing into much larger cells called macrophages,  with different appearances in various locations. Some roam through the  circulation and between cells and can coalesce into a single cell around a  foreign object to engulf it. Reticuloendothelial cells also interact with lym�  phocytes in immune reactions. Cells in the spleen destroy old red blood  cells and recycle their hemoglobin; uncontrolled, this process causes ane�  mia. Tumours of the reticuloendothelial system can be localized or wide�  spread throughout the body.

Light focused onto the retina by the lens of the eye stimulates  two types of light-sensitive cells: rods, which are sensitive to low light  levels, and cones, which provide detailed vision and colour perception.  Chemical changes in these cells trigger nerve impulses, which are  assembled by complex connections among retinal nerves into a pattern to  be carried through the optic nerve to the visual centres of the brain. Dis�  orders affecting the retina or the  macula in its centre decrease vision  and can cause blindness.

Observationally and historically, retrograde  motion refers to the apparent reversal of the planets� motion through the  stars for several months in each synodic period. This required a complex  explanation in Earth-centred models of the universe (see Ptolemy) but was  naturally explained in heliocentric models (see Copernican system) by the  apparent motion as Earth passed by a planet in its orbit. It is now known that  nearly all bodies in the solar system revolve and rotate in the same coun�  terclockwise direction as viewed from a position in space above Earth�s  North Pole. This common direction probably arose during the formation of  the solar nebula. The relatively few objects with clockwise motions (e.g.,  the rotation of Venus, Uranus, and Pluto) are also described as retrograde.</p><p>retrovirus \ l re-tro-'vI-r9s\ Any of a group of viruses that, unlike most  other viruses and all cellular organisms, carry their genetic blueprint in  the form of RNA. Retroviruses are responsible for some cancers and viral  infections of animals, and they cause at least one type of human cancer.  The retrovirus HIV is the cause of AIDS in humans. The name signifies  that they use RNA to synthesize DNA, the reverse of the usual cell pro�  cess. This process makes it possible for genetic material from a retrovi�  rus to enter and become a permanent part of the genes of an infected cell.</p><p>Retton, Mary Lou (b.

Second  only to Desiderius Erasmus among the German humanists, Reuchlin was a  pioneer in the scientific study of Classical Greek and translated many  Classical texts. His grammar and lexicon, On the Fundamentals of  Hebrew (1506), revolutionized Hebrew studies and advanced Old Testa�  ment research. His opposition to the Dominicans� plan to destroy all  Hebrew literature was one of the great controversies prior to the outbreak  of the Reformation, and in 1516 he was acquitted of heresy by a papal  commission. Philipp Melanchthon was his nephew.</p><p>Reunion \re-'yun-y3n\ Island (pop., 2005 est.: 780,000) and French  overseas department, Mascarene Islands, western Indian Ocean.

It consists mainly of rugged mountains dissected  by torrential rivers. Most of the population is of mixed ancestry, with  African descent predominant. Reunion was settled in the 17th century by  the French, who brought slaves from eastern Africa to work on coffee and  sugar plantations. It was a French colony until 1946, when it became an  overseas department of France. Its economy is based largely on the export  of sugar. Other products include meat and milk products, rum, molasses,  tobacco, geranium essence, and vanilla.</p><p>Reuter Vroi-tsrX, Paul Julius, Baron von Reuter orig. Israel  Beer Josaphat (b.

He  was a bank clerk and partner in a small publishing concern before initi�  ating a prototype news service in Paris in 1849, using electric telegraphy  and carrier pigeons in his network. He moved to England in 1851 and  opened a telegraph office serving banks, brokerage houses, and leading  business firms.

He became a local union  leader in Detroit, Mich., and helped organize sit-down strikes�during  which he suffered brutal physical attacks�that made the United Automo�  bile Workers (UAW) a power in the auto industry. As president of the UAW  from 1946 until his death, he was an effective negotiator of wages-and-  hours gains. He became president of the Congress of Industrial Organi�  zations (CIO) in 1952 and was an architect of the AFL-CIO merger in  1955. He was second in power to George Meany at the AFL-CIO; how�  ever, their repeated clashes, partly stemming from Reuther�s strong sup�  port for civil rights and opposition to the Vietnam War, resulted in  Reuther�s leading the UAW out of the AFL-CIO in 1968 and forming a  short-lived federation with the Teamsters Union. He died in a plane crash.</p><p>revelation Transmission of knowledge from a god or gods to humans.  In the Western monotheistic religions of Judaism, Christianity, and Islam,  revelation is the basis of religious knowledge. Humans know God and his  will because God has chosen to reveal himself to them. He may commu�  nicate with his chosen servants through dreams, visions, or physical mani�  festations and may inspire prophets who relay his message to the people.  His will may also be translated directly into writing through the handing  down of divine law (e.g., the Ten Commandments) or scripture (e.g., the Bible  and the Qur�an). Other religions emphasize �cosmic� revelation, in which  any and all aspects of the world may reveal the nature of a single under�  lying divine power (e.g., Brahman in the Vedas).</p><p>Revelation, Book of or Revelations or Apocalypse of John</p><p>Last book of the New Testament. It consists of two main parts, the first  containing moral admonitions to several Christian churches in Asia Minor,  and the second composed of extraordinary visions, allegories, and sym�  bols that have been the subject of varying interpretations throughout his�  tory. A popular interpretation is that Revelation deals with a contemporary  crisis of faith, possibly the result of Roman persecutions. It exhorts Chris�  tians to remain steadfast in their faith and hold firm to the hope that God  will ultimately vanquish their enemies. References to �a thousand years�  have led some to expect that the final victory over evil will come after  the completion of a millennium (see millennialism).

The son of free blacks, he traveled to Indiana and Illinois to receive the  education that was denied him in the South. Ordained a minister, he  became a pastor and principal of a Baltimore school for African Ameri�  cans. In the American Civil War he helped organize African American vol�  unteer regiments for the Union army. After the war he moved to Natchez,  Miss., and was elected state senator in 1869. In 1870 he was elected to  the U.S. Senate to fill the unexpired term of Jefferson Davis, becoming the  first African American elected to that body. He later served as president  of Alcorn A&amp;M College (1871-74, 1876-83).</p><p>revenue bond or limited obligation bond Bond issued by a  municipality, state, or public agency authorized to build, acquire, or  improve a revenue-producing property such as a waterworks, electric gen�  erating plant, or railroad. Unlike general-obligation bonds, which are  repaid through a variety of tax sources, revenue bonds are payable from  specified revenues only, usually the revenues from the facility for which  the bond was originally issued. Revenue bonds typically pay interest rates  higher than those of general-obligation bonds. The separation of the rev�  enue bond obligation from a municipality�s other bond obligations allows  the municipality to circumvent legislated debt limits.</p><p>revenue sharing Funding arrangement in which one government unit  grants a portion of its tax income to another government unit.

Laws  determine the formulas by which revenue is shared, limiting the controls  that the unit supplying the money can exercise over the receiver and  specifying whether matching funds must be supplied by the receiver.  Forms of revenue sharing have been used in several countries, including  Canada, India, and Switzerland. From 1972 to 1986 the U.S. pursued a  revenue-sharing program in which state and local governments received  federal funds to spend as they saw fit.</p><p>reverberatory furnace Furnace used for smelting, refining, or melt�  ing in which the fuel is not in direct contact with the contents but heats  it by a flame blown over it from another chamber. Such furnaces are used  in copper, tin, and nickel production, in the production of certain concretes  and cements, and in aluminum recycling. In steelmaking, this process (now  largely obsolete) is called the open-hearth process. The heat passes over  the hearth and then radiates back (reverberates) onto the contents. The  roof is arched, with the highest point over the firebox. It slopes downward  toward a bridge of flues that deflects the flame so that it reverberates.</p><p>Revere, Paul (b.

An ardent supporter of the colonists� cause, he  took part in the Boston Tea Party. As the principal rider for Boston�s Com�  mittee of Safety, he arranged to signal the British approach by having lan�  terns placed in Boston�s Old North Church steeple: �One if by land and  two if by sea.� On April 18, 1775, he set off to ride to Lexington to alert  colonists that British troops were on the march and to warn Samuel Adams  and John Hancock to flee. Though he was stopped by a British patrol, he  was able to alert the patriot leaders; because of his warning, the minute-  men were prepared for the Battle of Lexington and the start of the Ameri�  can Revolution. His ride was celebrated in a famous poem by Henry W.  Longfellow (1863). During the war. Revere constructed a powder mill to  supply colonial arms. After the war he discovered a process for rolling  sheet copper and opened a rolling mill that produced sheathing for ships  such as the USS Constitution.

The  spiritual fervour of revival-style preaching, typically performed by itin�  erant, charismatic preachers before large gatherings, is thought to have a  restorative effect on those who have been led away from the right path.  Various Protestant sects have experienced periods of revivalism at differ�  ent times since the 17th century, and many, notably Methodism, came into  being during revivalist periods. Common themes are strict interpretation  of the Bible, rejection of literary or historical study of the Bible, emphasis  on the conversion experience, and a call to live devoutly. Revivalism can  be interpreted as a precursor of 20th-century Christian fundamentalism. See  also Great Awakening; Dwight Moody.</p><p>revolution In politics, fundamental, rapid, and often irreversible change  in the established order. Revolution involves a radical change in govern�  ment, usually accomplished through violence, that may also result in  changes to the economic system, social structure, and cultural values. The  ancient Greeks viewed revolution as the undesirable result of societal  breakdown; a strong value system, firmly adhered to, was thought to pro�  tect against it. During the Middle Ages, much attention was given to find�  ing means of combating revolution and stifling societal change. With the  advent of Renaissance humanism, there arose the belief that radical  changes of government are sometimes necessary and good, and the idea  of revolution took on more positive connotations. John Milton regarded  it as a means of achieving freedom, Immanuel Kant believed it was a force  for the advancement of mankind, and G.W.F. Hegel held it to be the ful�  fillment of human destiny. Hegel�s philosophy in turn influenced Karl  Marx.

Some early versions, known as pepperboxes, had several barrels, but as  early as the 17th century pistols were being made with a revolving cham�  ber to load cartridges into a single barrel. The first practical revolver was  not designed until 1835, when Samuel Colt patented his version. He estab�  lished the standard of a cylinder with multiple chambers, each of which  successively locked in position behind the barrel and was discharged by  pressure on the trigger. In Colt�s early single-action revolvers, the cylin�  der revolved as the hammer was cocked manually. Double-action revolv�  ers, in which the hammer is cocked and the cylinder revolves as the trigger  is pulled, were developed soon afterward, along with metal cartridges.</p><p>revue Theatrical production of brief, loosely connected, often satirical  skits, songs, and dances. Originally derived from the medieval French  street fair, the modern revue dates from the early 19th century with the  Parisian Folies Marigny and later at the Folies-Bergere. The English revue  developed in two forms: one as the costume display and spectacle of the  Court Theatre productions in the 1890s and another as the Andre Chariot  Revues of the 1920s and the London Hippodrome shows, which empha�  sized clever repartee and topicality. In the U.S. the Ziegfeld Follies began  in 1907 and usually featured a star personality.

Sept. 21, 1966, Paris) French politician and premier (1940). After serv�  ing in World War I, he served in the Chamber of Deputies (1919-24,  1928^-0) and in cabinet positions (1930-32). As minister of finance  (1938^40) and premier (1940), he called on France to resist Nazi Ger�  many. After the German invasion, Reynaud resigned rather than conclude  an armistice; he was arrested and kept in captivity (1940-45). He returned  to the Chamber of Deputies (1946-62) and helped draft the constitution  of the Fifth Republic.</p><p>Reynolds, Sir Joshua (b. July 16, 1723, Plympton, Devon, Eng.�d.  Feb. 23, 1792, London) British portrait painter. Son of a clergyman-  schoolmaster, he was apprenticed to a London portraitist in 1740. His  large group portrait The Eliot Family (c. 1746) reveals the influence of  Anthony Van Dyck. The impressions he gained during two years in Italy  (1750-52), particularly in Venice, inspired his painting for the rest of his  life. He established a portrait studio in London in 1753 and was imme�  diately successful. His early London portraits introduced new vigour into  English portraiture. After 1760, with the increasing vogue for Greco-  Roman antiquity, his style became increasingly Classical and self-  conscious. He was elected the first president of the Royal Academy in  1768. Through his art and teaching, Reynolds led British painting away  from the anecdotal pictures of the early 18th century toward the formal  rhetoric of continental academic painting. His Discourses Delivered at the  Royal Academy (1769-90), advocating rigorous academic training and  study of the Old Masters, ranks among the most important art criticism  of the time.</p><p>Reynolds, Osborne (b. Aug. 23, 1842, Belfast, Ire.�d. Feb. 21,  1912, Watchet, Somerset, Eng.) British engineer and physicist. Educated  at Cambridge University, he became the first professor of engineering at  the University of Manchester (1868). Best known for his work in hydrau�  lics and hydrodynamics, he formulated the law of resistance in parallel  channels (1883), the theory of lubrication (1886), and the standard math�  ematical framework used in turbulence work (1889). He studied wave  engineering and tidal motions in rivers and made pioneering contributions  to the concept of group velocity. The Reynolds stress in fluids with tur�  bulent motion and the Reynolds number are named for him.</p><p>Reynolds American Inc. formerly R.J. Reynolds Tobacco  Holdings, Inc. U.S.-based tobacco company. Its origins date to the  establishment of Richard Joshua Reynolds�s tobacco-plug factory in Win�  ston, N.C., in 1875, producing plug tobacco (compressed cakes). The  Reynolds Tobacco Co. became a major manufacturer of tobacco products,  notably Camel, Winston, and Salem cigarettes. After embarking on a pro�  gram of diversification in the 1960s, the firm adopted the name R.J. Rey�  nolds Industries, Inc., in 1970 and purchased Nabisco Brands in 1985.  The new company, named RJR Nabisco in 1986, was acquired in 1989  by Kohlberg Kravis Roberts &amp; Co. (KKR) for $25 billion, the largest cor�  porate transaction of its time. KKR divested its ownership in 1995. R.J.  Reynolds returned to its primary business of tobacco marketing and  merged with British-owned rival Brown &amp; Williamson Tobacco Corp. in  2004 to create Reynolds American.</p><p>Reynolds number In fluid mechanics, a number that indicates whether  the flow of a fluid (liquid or gas) is absolutely steady (in streamlined, or  laminar flow) or on the average steady with small, unsteady changes (in  turbulent flow; see turbulence). The Reynolds number, abbreviated N Re or  Re, has no dimensions (see dimensional analysis) and is defined as the size  of the flow�as, for example, the diameter of a tube (D) times the aver�  age speed of flow (v) times the mass density of the fluid (p)�divided by  its absolute viscosity (p). Osborne Reynolds demonstrated in 1883 that the  change from laminar to turbulent flow in a pipe occurs when the value of  the Reynolds number exceeds 2,100.</p><p>Rg Veda See Rig Veda</p><p>Rh blood-group system System for classifying blood according to  presence or absence of the Rh antigen (factor) in erythrocytes. Rh-negative  persons who receive Rh-positive blood transfusions produce antibodies to  Rh factor, which attack red blood cells with the factor if they are ever  received again, causing serious illness and sometimes death. The antibod�  ies also attack the red cells of an Rh-positive fetus carried by an  Rh-negative woman if she has had a previous Rh-positive transfusion or</p><p>pregnancy (see erythroblastosis fetalis). The Rh-negative trait is rare world�  wide but more common in some ethnic groups.

The bullet-shaped virus particle is encased in a fatty  membrane and contains RNA.</p><p>Rhaetia See Raetia</p><p>Rhaetian Vre-teonN Alps Segment of the central Alps located mainly  in Switzerland but also extending along the Italian-Swiss and Austrian-  Swiss borders. Bernina Peak, on the Italian border, is the highest point,  at elevation 13,284 ft (4,049 m). In the eastern section is the Swiss  National Park, founded in 1914, with an area of 65 sq mi (169 sq km); it  is known for its rugged Alpine scenery and its wildlife.</p><p>Rhagae or Ragae \'ra-je\ Persian Rey Ancient city. Media. It was  formerly one of the great cities of Iran; its ruins are at modern Rey, near  Tehran. Settlement there dates from the 3rd millennium bc. Under the  Sasanian dynasty (3rd-7th centuries ad), it was a centre of Zoroastrian�  ism. It was captured by the Muslims in ad 641. It grew in importance until  the 12th century, when it was weakened by religious conflicts. In 1220 it  was destroyed by the Mongols, and its inhabitants were massacred. It was  famous for its decorated silks and for ceramics. The 'Abbasid caliph HarOn  al-Rashid, memorialized in The Thousand and One Nights, was born there  c. 765. The only remaining architectural features are two towers.</p><p>Rhazes See al-RAzi</p><p>Rhea Vre-s\ Greek goddess, one of the Titans.

The common rhea ( Rhea americana )  is about 4 ft (120 cm) tall and weighs about 50 lbs (20 kg). It has luxu�  riant plumage, brown or gray above and whitish below. Darwin�s rhea  (Pterocnemia pennata ) is smaller and has white-tipped brownish plum�  age. Rheas live in open country, often among grazing animals, and run  from predators. They eat a wide variety of plants and animals. Both spe�  cies are listed as endangered.</p><p>Rhee, Syngman (b. March 26, 1875, Whang-hae, Korea�d. July 19,  1965, Honolulu, Hawaii, U.S.) First president of the Republic of Korea  (South Korea). The first Korean to earn a Ph.D. at a U.S. university (Prince�  ton), he returned to Korea in 1910, the year Japan annexed Korea. Unable  to hide his hostility toward Japanese rule, he left again for the U.S. in 1912.  For the next 30 years he spoke out for Korean independence; in 1919 he  was elected president of a provisional government in exile. As the only  Korean leader well known to the U.S., Rhee was returned to Korea ahead  of his rivals at the end of World War II; he was elected president of the  Republic of Korea in 1948. He held that post until 1960, when opposition  to his authoritarian policies (which included outlawing the opposition Pro�  gressive Party) forced his resignation. He died in exile.</p><p>Rheims See Reims</p><p>rhesus \'re-sos\ monkey Sand-coloured macaque ( Macaca mulatto).</p><p>widespread in South and Southeast  Asian forests. Rhesus monkeys are  17-25 in.

It may entail the study  of principles and rules of composition formulated by critics of ancient  times, and it can also involve the study of writing or speaking as a means  of communication or persuasion. Classical rhetoric probably developed  along with democracy in Syracuse (Sicily) in the 5th century bc, when  dispossessed landowners argued claims before their fellow citizens.  Shrewd speakers sought help from teachers of oratory, called rhetors. This  use of language was of interest to philosophers such as Plato and Aris�  totle because the oratorical arguments called into question the relation�  ships among language, truth, and morality. The Romans recognized  separate aspects of the process of composing speeches, a compartmental-  ization that grew more pronounced with time. Renaissance scholars and  poets studied rhetoric closely, and it was a central concern of humanism.  In all times and places where rhetoric has been significant, listening and  reading and speaking and writing have been the critical skills necessary  for effective communication.</p><p>rheumatic \ru-'ma-tik\ fever Generalized disease caused by certain  types of streptococcus bacteria. It occurs mostly in children and young  adults. Symptoms may be mild or severe. Sudden fever, joint pain, and  inflammation may begin days to weeks after a streptococcal infection,  usually of the throat (see pharyngitis). Other symptoms may include skin  nodules and rashes, chorea, abdominal pain, nosebleeds, and weight loss.  Heart inflammation, with accompanying rapid heartbeat, murmurs, and  enlargement, can lead to valve scarring, markedly shortening life. After  recovery, survivors are prone to future attacks. Penicillin given when the  initial infection is diagnosed can prevent it. Otherwise, salicylic acid  derivatives or corticosteroids help the symptoms.</p><p>rheumatoid Vrii-mo-.tokB arthritis Chronic, progressive autoimmune  disease causing connective-tissue inflammation, mostly in synovial joints. It  can occur at any age, is more common in women, and has an unpredict�  able course. It usually starts gradually, with pain and stiffness in one or  more joints, then swelling and heat. Muscle pain may persist, worsen, or  subside. Membrane inflammation and thickening scars joint structures and  destroys cartilage. In severe cases, adhesions immobilize and deform the  joints, and adjacent skin, bones, and muscles atrophy. If high-dose aspi�  rin, ibuprofen, and other NSAIDs do not relieve pain and disability, low-  dose corticosteroids may be tried. Physical medicine and rehabilitation  with heat and then range-of-motion exercises reduce pain and swelling.  Orthopedic appliances correct or prevent gross deformity and malfunc�  tion. Surgery can replace destroyed hip, knee, or finger joints with pros-  theses. There is also a juvenile form of the disease.</p><p>Rhiannon \hre-'a-non\ Welsh manifestation of the Gaulish horse god�  dess Epona and the Irish goddess Macha. She is best known from the  Mabinogion, in which she makes her appearance on a pale, mysterious  steed and meets King Pwyll, whom she marries. Unjustly accused of kill�  ing her infant son, she was forced to carry people on her back like a horse  until she was vindicated by her son�s return.</p><p>Rhine, Confederation of the See Confederation of the Rhine</p><p>Rhine River German Rhein River, western Europe. Rising in the Swiss  Alps, it flows north and west through western Germany to drain through  the delta region of The Netherlands into the North Sea. It is 820 mi (1,319  km) long and navigable for 540 mi (870 km). Its many canals connect it  with the Rhone, Marne, and Danube river systems. It has been an inter�  national waterway since 1815 (see Congress of Vienna). It has played a  prominent part in German history and legend. During World War II its  course was a major line of defense. Major cities along its banks include  Basel, Mannheim, Koblenz, Cologne, Duisburg, and Rotterdam.</p><p>Rhineland German Rheinland Region of Germany. It is located west  of the Rhine River and encompasses the states of Saarland and Rhineland-  Palantinate and portions of Baden-Wiirttemberg, Hesse, and North Rhine-  Westphalia. The chief city of the Rhineland is Cologne. In the 19th  century the Rhineland became the most prosperous area of Germany. After  World War I, Allied troops occupied portions of the area on the border  with France, and it was the scene of recurrent crises and controversies  during the 1920s. In 1936 Adolf Hitler ordered German troops to enter the  demilitarized zone of the Rhineland; weak objections by the Allies fore�  shadowed Hitler�s later annexation of the Sudetenland.</p><p>rhinoceros Any of five extant African and Asian species (family Rhi-  nocerotidae) of three-toed horned ungulates. One of the largest of all land  animals (the white rhinoceros is second only to the elephant), the rhinoc�</p><p>eros is particularly distinguished by  one or two horns�growths of kera�  tin, a fibrous hair protein�on its  upper snout. All have thick, virtually  hairless skin that, in the three Asian  species, forms platelike folds at the  shoulders and thighs. Rhinos grow to  8-14 ft (2.5-4.3 m) long and 3-6.5  ft (1.5-2 m) tall; adults weigh 3-5  tons. Most are solitary inhabitants of  open grassland, scrub forest, or  marsh, but the Sumatran rhino lives  in deep forest. The African black  rhino browses on succulent plants,  the white and great Indian rhinos  graze on short grasses, and the  Sumatran and Javan rhinos browse  on bushes and bamboo. In the second  half of the 20th century, the rhinoc�  eroses were brought to the brink of  extinction by hunters, mostly seek�  ing the horn, which is valued in Asia  as an aphrodisiac. The white rhinoceros of Africa is no longer endangered,  but the population of the other four species combined is only a few thou�  sand, almost all of which live on reserves.</p><p>rhinovirus \ l ri-n6-'vl-r3s\ Any of a group of picornaviruses capable of  causing common colds in humans. The virus is thought to be transmitted  to the upper respiratory tract by airborne droplets. Because of the great  number of cold viruses, vaccines against them are virtually impossible to  develop. See also adenovirus.</p><p>rhizome Horizontal underground plant stem capable of producing the  upward shoot and downward root systems of a new plant. This capabil�  ity allows vegetative (asexual) propagation and enables plants to survive  an annual unfavourable season underground. In some plants (e.g., water  lilies, many ferns, and forest herbs), the rhizome is the only stem of the  plant. In such cases, only the leaves and flowers are readily visible.</p><p>Rhode Island officially Rhode Island and Providence Plan�  tations State (pop., 2000: 1,048,319), northeastern U.S. One of the New  England states and the smallest U.S. state, it covers 1,212 sq mi (3,139  sq km); its capital is Providence. Rhode Island is bordered by Massachu�  setts on the north and east, and Connecticut on the west. The Rhode Island  Sound on the south is the basis of the state�s fishing industry. The origi�  nal inhabitants of the area were Narragansett Indians. The first European  settlement was in 1636 by Roger Williams and his followers, who were  banished from Massachusetts; in 1663 King Charles II granted a charter  to Williams. Though it never officially joined the New England colonies  in King Philip's War, it suffered greatly when many settlements were  burned. It was at the forefront of the fight against British customs laws  that led to the American Revolution. An original state of the Union, in 1790  it was the 13th state to ratify the Constitution, agreeing only after the Bill  of Rights was included. The state�s original charter remained in effect until  Dorr�s Rebellion (see Thomas W. Dorr) in 1842 led to extension of suf�  frage. The cotton-textile mill built by Samuel Slater in Pawtucket in 1790  initiated the Industrial Revolution in the U.S. Manufacturing is still impor�  tant to the economy, and products include jewelry and silverware, textiles  and clothing, and electrical machinery and electronics.</p><p>Rhode Island School of Design (RISD) One of the most eminent  fine arts colleges in the U.S., located in Providence, R.I. It was founded  in 1877 but did not offer college-level instruction until 1932. It combines  professional arts training with a broad liberal arts curriculum, offering  bachelor�s and master�s degrees in the design, fine arts, and other fields.  Its art museum has extensive collections of American painting and deco�  rative arts.</p><p>Rhodes Greek Rodhos Vr6-,th6s\ Island of Greece. It is the largest  island of the Dodecanese group and the most easterly in the Aegean Sea.  Its main city, Rhodes (pop., 2001: 53,709), lies at the northern tip of the  island. The earliest known settlers were the Dorians c. 1000 bc. During  the Classical period the island�s affiliations vacillated between Athens,  Sparta, and Persia in attempts to preserve a balance of power. A devas�  tating earthquake c. 225 bc destroyed the Colossus of Rhodes, one of the  Seven Wonders of the World.

The knights converted the island into a fortress and held it for two  centuries until 1523, when the Turks took control. In 1912 it was taken  from Turkey by Italy, and in 1947 it was awarded by treaty to Greece. A  year-round tourist industry has brought prosperity to the island.</p><p>Rhodes, Alexandre de (b. March 15, 1591, Avignon, France�d.  March 5, 1660, Esfahan, Iran) French missionary, the first Frenchman to  visit Vietnam. He established a Jesuit mission in the region in 1619 and  later estimated that he had converted some 6,700 Vietnamese to Roman  Catholicism. Expelled in 1630, he spent 10 years teaching philosophy in  Macau before returning, only to be exiled again in 1646. The Vatican  sponsored a Vietnamese missionary program in 1658 based on de  Rhodes�s ideas, but he himself was sent to Iran (Persia), where he died.  He wrote a Vietnamese-Latin-Portuguese dictionary and perfected the  romanized script Quoc-ngu (developed by earlier missionaries), which  facilitated communicating Christian doctrines to the Vietnamese and  increased the literacy rate among the population.</p><p>Rhodes, Cecil (John) (b. July 5, 1853, Bishop�s Stortford, Hertford�  shire, Eng.�d. March 26, 1902, Muizenberg, Cape Colony) Financier,  statesman, and empire builder of British South Africa. Rhodes grew up  in the English countryside and in 1871 was sent to assist his brother in  business in South Africa, where he became interested in diamond mining.  He founded De Beers Consolidated Mines (1888), and by 1891 his com�  pany was mining 90% of the world�s diamonds. Seeking expansion to the  north and dreaming of building a Cape-to-Cairo railway, he persuaded  Britain to establish a protectorate over Bechuanaland (1884), clashing  with Boer president Paul Kruger. He obtained digging concessions from  Lobengula (1889), but in 1893 Rhodes overran him militarily. At his insti�  gation Britain chartered the British South Africa Co. (1889) and put  Rhodes in charge. He extended the company�s control to two northern  provinces, which were eventually named after him as Southern Rhodesia  (now Zimbabwe) and Northern Rhodesia (now Zambia). Interested in the  mineral-rich Transvaal, he plotted to overthrow Kruger (1895); the attempt  was botched by Leander Starr Jameson, and Rhodes was forced to resign  as prime minister of Cape Colony and head of the British South Africa  Co. His last years were marked by disappointment and scandal brought  about by the scheming of Princess Radziwill. His will bequeathed most  of his fortune to establishing the Rhodes scholarship.</p><p>Rhodes, Colossus of Enormous  that towered more than 100 ft (30 m)  over the harbour at the city of Rhodes  in Greece. The work of Chares of  Lindos, the statue commemorated the  raising of Demetrios Poliorcetes�  long siege of Rhodes (305-304 bc).  One of the Seven Wonders of the  World, it was toppled by an earth�  quake c. 225 bc.

Named after British colonial adminis�  trator Cecil Rhodes, it was administered by the British South Africa Com�  pany in the 19th century and exploited mostly for its gold, copper, and  coal deposits. In 1911 it was divided into Northern and Southern Rhode�  sia; Southern Rhodesia became a self-governing British colony (1923) and  Northern Rhodesia a British protectorate (1924). They joined with Nyasa-  land to become the Federation of Rhodesia and Nyasaland (1953-63).

It divided the cost of the  losses among the shipowner, the owners of the cargo, and the passengers,  thus serving as a form of insurance against storms and piracy. It was  effective from the 7th through the 12th century.</p><p>rhodium Metallic chemical element, one of the transition elements,  chemical symbol Rh, atomic number 45. Chemically related to platinum,  it is a precious, silver-white metal mainly used as an alloying agent for  the latter element. Rhodium added to platinum in small amounts yields  alloys that are harder and that lose mass at high temperatures more slowly  than pure platinum. Such alloys are used for laboratory furnace crucibles,  spark-plug electrodes, catalysts in very hot chemical environments  (including automobile catalytic converters), and high-temperature thermo�  couples. Because rhodium resists tarnishing at ordinary temperatures and  is highly reflective, it is in demand as a surface electroplating for jewelry  and other decorative articles. The plated metal is also used for reflecting  surfaces in optical instruments.</p><p>rhodochrosite \ l ro-d3- , kro-,sIt\ Carbonate mineral composed of man�  ganese carbonate (MnC0 3 ), a source of manganese for the ferromanga�  nese alloys used in steel production.

It is composed of opsin, a protein,  linked to retinal, a conjugated molecule (see conjugation) formed from  vitamin A. Photons of light that enter the eye are absorbed by retinal and  cause it to change its configuration, starting a biochemical chain of events  that ends with impulses being sent along the optic nerve to the brain. In  bright light, to protect rod cells from overstimulation, rhodopsin breaks  down into retinal and opsin, both of which are colourless. In dim light or  darkness the process is reversed (dark adaptation), and purple-red rhodop�  sin is reformed. Similar light-sensitive compounds made of retinal and  other opsin proteins are the pigments in the retina�s cone cells responsible  for colour vision in bright light.</p><p>Rhone River River, Switzerland and France. A historic southern gate�  way, as well as the only major European river flowing directly to the  Mediterranean Sea, the Rhone is 505 mi (813 km) long and navigable for  about 300 mi (485 km). It is Alpine in character, and its course has been  shaped by neighbouring mountain systems. Rising in the Swiss Alps, it  flows into Lake Geneva, then crosses into France through the Jura Moun�  tains. It continues south through Lyon, Avignon, and Tarascon to Arles  and enters the Mediterranean west of Marseille.</p><p>rhubarb Any of several species of the genus Rheum (family Polygo-  naceae), especially R. rhaponticum  (or R. rhabarbarum ), a hardy peren�  nial grown for its large, succulent,  edible leafstalks. Rhubarb is best  adapted to the cooler parts of the tem�  perate zones. The fleshy, tart, and  highly acid leafstalks are used in pies,  compotes and preserves, and some�  times as the base of a wine or an  aperitif. The roots withstand cold  well. The huge leaves that unfold in  early spring are toxic to cattle and  humans; later in the season a large  central flower stalk may bear numerous small, greenish-white flowers and  angular, winged fruits. Rhubarb root has long been considered to have  cathartic and purgative properties.</p><p>rhyme Type of echoing produced by the close placement of two or more  words with similarly sounding final syllables. Rhyme is used in poetry  (and occasionally in prose) to produce sounds that appeal to the ear and  to unify and establish a poem�s stanzaic form. End rhyme (i.e., rhyme  used at the end of a line to echo the end of another line) is most com�  mon, but internal rhyme (occurring before the end of a line) is frequently  used as an embellishment. Types of �true rhyme� include masculine  rhyme, in which the two words end with the same vowel-consonant com�  bination (stand/land); feminine rhyme (or double rhyme), in which two  syllables rhyme (profession/discretion); and trisyllabic rhyme, in which  three syllables rhyme (patinate/latinate).</p><p>rhyolite Vrl-o-.lItV Igneous rock that is the volcanic equivalent of gran�  ite, whose chemical composition is similar.

Ella Gwendolen Rees William (b. Aug.  24, 1890, Roseau, Dominica, Windward Islands, West Indies�d. May 14,  1979, Exeter, Devon, Eng.) Dominican-born British novelist. Rhys left  the West Indies for London to study acting at age 16. She later moved to  Paris, where she was encouraged to write by Ford Madox Ford. She earned  acclaim for short stories and novels set in the bohemian world of Europe  in the 1920s and �30s, including Good Morning, Midnight (1939). After  settling in Cornwall, she published nothing for nearly three decades before  producing Wide Sargasso Sea (1966), a memorable novel about Mr. Roch�  ester�s mad first wife in Charlotte Bronte�s Jane Eyre (see Bronte sisters);  and two story collections.</p><p>rhythm and blues (R&amp;B) Any of several closely related musical  styles developed by African American artists. The various styles were  based on a mingling of European influences with jazz rhythms and tonal  inflections, particularly syncopation and the flatted blues chords. They  grew out of the blues of the rural South, which blended work chants with  songs of deep emotion, and were greatly influenced by gospel music. Three  major forms were distinguishable. The earliest, called race , was the style  of the �jump� band, which emphasized strong rhythm, solo work (espe�  cially by saxophones), and vocals in a shout-blues manner. A second form,  often called Chicago blues, was exemplified by performers such as Muddy  Waters and was typically played by a small group with amplified instru�  ments. The third major form was primarily vocal, featuring close, gospel-  influenced harmonies often backed by an orchestra. In the mid-1950s the  term rhythm and blues was adopted by the music industry for music  intended for the African American audience; with the gradual disappear�  ance of racial barriers, the Chicago blues style began to seem less a vital  form than a folk tradition, while the gospel style was transformed into the  soul music of vast appeal. Rhythm and blues was the chief antecedent of  ROCK MUSIC.</p><p>rhythm and metre Two aspects of the organization of time in music.  Rhythm is the placement of musical sounds in time. Metre, like poetical  metre, is usually a regular pattern of beats and provides the context in  which rhythm is understood. In Western notated music, metre is indicated  by means of a time signature�in which the lower number specifies the  basic unit or subunit of the beat (e.g., 8 usually indicates that eighth-notes  are the basic subunit) and the upper number specifies the number of beats  in a measure�at the beginning of a piece or movement, and by the ver�  tical bar lines that divide the piece into measures.</p><p>rhythmic sportive gymnastics Athletic competition related to gym�  nastics and dance in which participants, individually or in groups, per�  form exercise routines with the aid of hand apparatuses such as ropes,  hoops, balls, clubs, and ribbons. In scoring points, artistry counts more  than acrobatics. The sport dates from the 18th century. Though some  gymnasts participated at the Olympic Games from 1948 to 1956, not until  1984 did it become an official Olympic competitive event.</p><p>Ribalta \re-'bal-ta\, Francisco (b. 1565, Castellon de la Plana,  Spain�d. Jan. 12, 1628, Valencia) Spanish painter. His early works are  Mannerist. After settling in Valencia in 1598, he developed a darker and  more naturalistic style (e.g., his Santiago altarpiece, 1603) under the influ�  ence of Caravaggio. After 1612 he achieved originality and grandeur in  such paintings as Christ Embracing St. Bernard. His later paintings,  marked by powerfully modeled forms, simplicity of composition, and  naturalistic lighting, anticipate the work of Diego Velazquez, Francisco  Zurbaran, and Jose de Ribera.</p><p>Ribat See Rabat</p><p>Ribaut \re-'b6\, Jean (b. c. 1520, Dieppe, France�d. Oct. 12, 1565,  Florida) French naval officer and colonizer. He served in the French navy  under Gaspard II de Coligny, who in 1562 sent him to found a French  Huguenot colony in Florida. He landed at the mouth of the St. Johns River  (Florida), then sailed north to establish Charlesfort (now in South Caro�  lina). He returned to France, then was sent back to Florida (1565) to rein�  force the French colony of Fort Caroline on the St. Johns River. Spanish  claims to the region led to the attack and destruction of the colony by  Pedro Menendez de Aviles, who massacred the French, including Ribaut.</p><p>Ribbentrop Vri-bsn-.trapV Joachim von (b. April 30, 1893, Wesel,  Ger.�d. Oct. 16, 1946, Niirnberg) German diplomat and foreign minis�  ter under the Nazi regime. After serving in World War I, he became a  wine merchant. He met Adolf Hitler in 1932 and became his chief adviser  on foreign affairs. He negotiated the Anglo-German Naval Agreement and  served as ambassador to Britain (1936-38), advising Hitler that Britain  could not aid Poland effectively. As foreign minister (1938�45), he nego�  tiated the Pact of Steel with Italy, the German-Soviet Nonaggression Pact,  and the Tripartite Pact with Japan and Italy. His influence waned in World  War II, after which he was found guilty at the Niirnberg trials and hanged.</p><p>Ribble, River River, northwestern England. It is 75 mi (120 km) long. It  rises in North Yorkshire and flows south and west through Lancashire into  the Irish Sea through an estuary extending from Preston.

Though bom in Spain, where he is said to have trained under  Francisco Ribalta, he spent most of his life in Naples (then a Spanish pos�  session). Most of his works are of religious subjects. Dramatic light and  shadow and sometimes horrific detail emphasize the mental and physical  suffering of penitent or martyred saints, as in The Martyrdom of St. Bar�  tholomew (c. 1630). In later works his modeling is softer, his colours are  richer, and he demonstrates strong human sympathy, as in The Clubfooted  Boy (1642). His etchings are among the finest produced in Italy and Spain  in the Baroque period.</p><p>riboflavin V.ri-bo-'fla-vonX or vitamin B 2 Yellow, water-soluble  organic compound, abundant in whey and egg white. It has a complex  structure incorporating three rings. Green plants and most microorgan�  isms can synthesize it; animals need to acquire it in their diet. It exists in  combined forms as coenzymes and functions in the metabolism of carbohy�  drates and amino acids. A syndrome resembling pellagra is thought to result  from riboflavin deficiency. See also flavin.</p><p>ribose \'rI-,bos\ Five-carbon sugar found in RNA. (In DNA the corre�  sponding sugar is the closely related deoxyribose.) A ribose molecule  combined with adenine, guanine, cytosine, or uracil forms a nucleoside;  adding a phosphate group forms a nucleotide. The ribose of one nucleotide  joins with the phosphate of the next to form the RNA backbone. Ribose  phosphates are components of various coenzymes and are used by micro�  organisms in synthesizing histidine.</p><p>ribosome Vri-ba-.somX Tiny particle, the site of protein synthesis, that  is present in large numbers in living cells. They occur both as free par�  ticles within cells and, in eukaryotes, as particles attached to the mem�  branes of the endoplasmic reticulum. They are 40% protein and 60% RNA.  Ribosomes account for a large proportion of the total RNA of a cell. Pro�  teins newly formed on ribosomes detach and migrate to other parts of the  cell to be used.</p><p>Ricardo, David (b. April 18/19, 1772, London, Eng.�d. Sept. 11,  1823, Gatcombe Park, Gloucestershire) British economist. The son of a  Dutch Jew, he followed his father into the London stock exchange, where  he made a fortune before turning to the study of political economy, in  which he was influenced by the writings of Adam Smith. His writings in  support of a metal currency standard were influential. In his major work,  The Principles of Political Economy and Taxation (1817), he examined  the movement of wages and the determination of value, asserting that the  domestic values of commodities were largely determined by the labour  required for their production. His Iron Law of Wages stated that attempts  to improve the real income of workers were futile and that wages tended  to stabilize at subsistence level. Though many of his ideas are obsolete,  he was a major figure in the development of classical economics and is  credited as the first person to systematize economics.</p><p>Ricci \'ret-che\, Matteo (b. Oct. 6, 1552, Macerata, Papal States�d.  May 11, 1610, China) Italian Jesuit missionary who introduced Christian�  ity to China. From a noble family, he was educated by the Jesuits, whose  order he joined after studying law in Rome. He volunteered for mission�  ary work overseas, arrived in Goa in 1578, and proceeded to China in  1582. China�s interior was closed to foreigners when he arrived, but his  willingness to adopt the Chinese language and culture gave him entry. In  1597 he was appointed director of Jesuit activities in China. In 1599 he  settled in Nanjing, where he studied astronomy and geography. In 1601  he was finally admitted to Beijing, where he preached the Gospel, taught  science to scholars, and translated Christian works into Chinese.</p><p>Riccio \'ret-cho,\ English Vrich-e-.oV, David orig. Davide Rizzio (b.  c. 1533, Pancalieri, near Turin, Piedmont�d. March 9, 1566, Edinburgh,  Scot.) Secretary to Mary, Queen of Scots. The son of a musician, he  accompanied the duke of Savoy�s ambassador to Scotland and entered  Mary�s service as a musician (1561). He became her close adviser and  helped arrange her marriage to Lord Darnley (1565). Disliked because of  his arrogance, Riccio was an impediment to the Scottish nobles� plan to  remove Mary. While at dinner in Mary�s palace, he was seized by an  armed band of nobles, including Lord Ruthven, and stabbed to death.</p><p>rice Edible starchy cereal grain and the annual grass ( Oryza sativa, family  Poaceae, or Gramineae) that produces it. Roughly one-half of the world�s  population, including almost all of East and Southeast Asia, depends on  rice as its principal staple food. First cultivated in India more than 4,000  years ago, rice was planted gradually westward and is now cultivated  widely in flooded fields (paddies) and river deltas of tropical, semitropical,</p><p>and temperate regions. Growing to  about 4 ft (1.2 m) in height, rice has  long, flat leaves and an inflorescence  made up of spikelets bearing flowers  that produce the fruit, or grain.</p><p>Removal of just the husk produces  brown rice, containing 8% protein  and a source of iron, calcium, and B  vitamins. Removal of the bran layer  leaves white rice, greatly diminished  in nutrients. Enriched white rice has  added B vitamins and minerals.</p><p>So-called wild rice ( Zizania aquat-  ica) is a coarse annual grass of the  same family whose cereal grain, now  often considered a delicacy, has long  been an important food of North  American Indians.</p><p>Rice, Jerry (Lee) (b. Oct. 13,</p><p>1962, Starkville, Miss., U.S.) U.S.  gridiron football player. He won All-America honours at Mississippi Val�  ley State University. As a wide receiver for the San Francisco 49ers  (1985-2000), he was part of three Super Bowl championship teams (1988,  1989, and 1994). Standing 6 ft 2 in. (1.9 m). Rice was larger than the  typical NFL wide receiver of his era, and he used his size and strength to  overmatch defenders; he was also an exceptional runner. He completed  his career in 2005 as the all-time NFL leader in touchdowns (207), recep�  tions (1,549), receiving yards (22,895), and combined yardage (23,546).</p><p>Rice University Private university in Houston, Texas, U.S. It was  founded in 1891 and endowed by William Marsh Rice.

She was a student at Radcliffe College when her  poems were chosen for publication in the Yale Younger Poets series; the  resulting volume, A Change of World (1951), reflected her formal mas�  tery. Her subsequent work traces a transformation from well-crafted but  imitative poetry to a highly personal and powerful style. Her increasing  commitment to the women�s movement and a lesbian/feminist aesthetic  influenced much of her work. Among her collections are Diving into the  Wreck (1973, National Book Award) and The Dream of a Common Lan�  guage (1978). She also wrote compelling books of nonfiction, including  Of Woman Born (1976; National Book Award), On Lies, Secrets, and  Silence (1979), and What Is Found There (1993).</p><p>Rich, Buddy orig. Bernard Rich (b. June 30/Sept. 30, 1917, Brook�  lyn, N.Y., U.S.�d. April 2,1987, Los Angeles, Calif.) U.S. bandleader and  drummer. Rich was a child-prodigy vaudeville performer known as �Baby  Traps, the Drum Wonder.� He played with several of the great swing bands,  notably those of Artie Shaw (1939) and Tommy Dorsey (1939-42,1944-46),  before forming his own big band. In small ensembles, he worked with  many of the greatest jazz musicians in concerts and recordings during the  1950s. The clarity and speed of his drumming made him legendary.</p><p>Richard I known as Richard the Lionheart(ed) French Richard  Coeur de Lion (b. Sept. 8, 1157, Oxford, Eng.�d. April 6, 1199,  Chalus, Duchy of Aquitaine) Duke of Aquitaine (1168-99) and Poitiers  (1172-99) and king of England, duke of Normandy, and count of Anjou  (1189-99). He inherited Aquitaine from his mother, Eleanor of Aquitaine.  Denied real authority there, he rebelled against his father, Henry II (1173�  74) and later enlisted Philip II of France in a successful campaign against  Henry (1189). Crowned king of England on Henry�s death that year,  Richard embarked on the Third Crusade (1190), stopping in Sicily to name  Tancred king and conquering Cyprus. He won victories in the Holy Land,  but, after failing to gain Jerusalem, he signed a truce (1192) with Sala-  din. On his way home Richard was captured by Leopold of Austria and  turned over to Henry VI of Germany, who imprisoned him until a ransom  was paid (1194). Richard returned to England and reclaimed the throne  from his brother John, then spent the rest of his life in Normandy fight�  ing against Philip II.</p><p>Richard II (b. Jan. 6, 1367, Bordeaux�d.

The Black Death brought on  economic problems, leading to the Peasants' Revolt (1381), which Rich�  ard quelled with false promises. His enemies among the nobility placed  limits on his royal power (1386-89), but he later took revenge on them.  He banished John of Gaunt�s son, Henry, and confiscated his vast Lan�  castrian estates. While Richard was absent in Ireland, Henry invaded  England (1399) and seized power as Henry IV. Richard was then forced  to abdicate the throne. He was then imprisoned, and sometime in Febru�  ary 1400 he was executed; by means unknown.</p><p>Richard III (b. Oct. 2, 1452, Fotheringhay Castle, Northamptonshire,  Eng.�d. Aug. 22, 1485, Bosworth, Leicestershire) Last Yorkist king of  England. He was made duke of Gloucester in 1461 after his brother  Edward of York had deposed the weak Lancastrian king Henry VI and  assumed power as Edward IV. Richard and Edward were driven into exile  in 1470 but returned and defeated the Lancastrians in 1471. On Edward�s  death (1483), Richard became protector for Edward�s son, the 12-year-  old King Edward V, but he usurped the throne and confined Edward and  his little brother to the Tower of London, where they were murdered.  Henry Tudor (later Henry VII) raised an army against Richard, who was  defeated and killed at the Battle of Bosworth Field. Later Tudor histories  and William Shakespeare�s play Richard III painted Richard as a mon�  ster and were gross caricatures motivated by the new dynasty�s need to  denigrate its predecessor.</p><p>Richard, (Joseph Henri) Maurice (b. Aug. 4,1921, Montreal, Que.,  Can.�d. May 27,2000, Montreal) Canadian ice-hockey player. He played  right wing for the Montreal Canadiens (1942-60) and became the first  National Hockey League player to score 50 goals in a regular (50-game)  season (1943-44). His nickname, �Rocket,� reflected his speed and aggres�  sive play. He was also noted for his clutch scoring and fiery temper.</p><p>Richards, l(vor) A(rmstrong) (b. Feb. 26, 1893, Sandbach,  Cheshire, Eng.�d. Sept. 7, 1979, Cambridge, Cambridgeshire) English  critic and poet. While a lecturer at Cambridge, Richards wrote influential  works, including Principles of Literary Criticism (1924), in which he intro�  duced a new way of reading poetry that led to the New Criticism. A student  of psychology, he concluded that poetry performs a therapeutic function by  coordinating various human impulses into an aesthetic whole. In the 1930s  he spent much of his time developing Basic English, a language system of  850 basic words that he believed would promote international understand�  ing. He taught at Harvard University from 1944.</p><p>Richards, (Isaac) Vivian (Alexander) (b. March 7, 1952, St.  John�s, Antigua) West Indian professional cricket player. Bom into a sport�  ing family, Richards appeared in his first Test match for the West Indies  against India in 1974, but he came to prominence with a score of 192  while batting against India in his second Test that year. In 1976 Richards  scored a record 1,710 runs. His 56-ball century (scoring 100 points on 56  balls bowled) in 1985 is a record in Test cricket. Richards played a vital  role in the West Indies� two World Cup triumphs. He captained the West  Indies in 50 Tests with 27 victories and holds the record for never having  lost a series as captain. He was selected Wisden Cricketer of the Year in  1977 and was also one of the five cricketers of the century selected by  Wisden in 2000. He began coaching the West Indies team upon his retire�  ment as a player in 1991.</p><p>Richardson, Dorothy M(iller) (b. May 17, 1873, Abingdon, Berk�  shire, Eng.�d.

For much  of her life she worked on her sequence novel Pilgrimage, comprising 13  volumes beginning with Pointed Roofs (1915). The final volume, March  Moonlight, was published a decade after her death. A sensitive autobio�  graphical account of a woman�s developing consciousness, it was a pio�  neering work in stream-of-consciousness fiction.</p><p>Richardson, Henry Handel orig. Ethel Florence Lindesay  Richardson (b. Jan. 3, 1870, Melbourne, Austl.�d. March 20, 1946,  Fairlight, Sussex, Eng.) Australian-bom English novelist. In 1888 she left  Australia to study music in Germany, and she spent the rest of her life  abroad, settling in England in 1904 with her husband, J.G. Robertson. Mau�  rice Guest ( 1908), her antiromantic first novel, concerns a music student�s  disastrous love affair. Her masterpiece, The Fortunes of Richard Mahony,  3 vol.

Sept. 29, 1838, Priestley Plantation,  La., U.S.�d. April 27, 1886, Brookline, Mass.) U.S. architect. He studied  at Harvard University in Cambridge, Mass., and the Ecole des Beaux-Aits  in Paris. His designs for Boston�s Brattle Square (1870-72) and Trinity  (1872-77) churches won him a national reputation. He designed houses,  libraries, suburban railroad stations, educational buildings, and commer�  cial and civic structures. Instead of the narrow vertical proportions and  Gothic features used by his contemporaries, he favoured horizontal lines,  simple silhouettes, and large-scale Romanesque or Byzantine-inspired  details. The Crane Memorial Library in Quincy, Mass. (1880-82), with its  granite base, clerestory windows, tiled gable roof, and cavernous entrance  arch, stands among his finest mature works. His Romanesque style had an  integrity seldom achieved by his many imitators, and the functionalism of  his designs presaged the work of Louis H. Sullivan.</p><p>Richardson, John (b. Oct. 4, 1796, probably Fort George, Upper  Canada�d. May 12, 1852, New York, N.Y., U.S.) Canadian writer. His  experience in the British army in the War of 1812 and later abroad pro�  vided material for some of his writings. The first Canadian novelist to  write in English, he won acclaim with his third novel and only enduring  work, Wacousta (1832), a gothic story about the Indian uprising led by  Pontiac. His nonfiction includes Personal Memoirs of Major Richardson  (1838) and War of 1812 (1842).</p><p>Richardson, Sir Ralph (David) (b. Dec. 19, 1902, Cheltenham,  Gloucestershire, Eng.�d.

He made  his screen debut in 1933 and became known for playing urbane, witty  characters and later for eccentric old men. His many films included The  Fallen Idol (1948), Doctor Zhivago (1965), and Grey stoke (1984).</p><p>Richardson, Samuel (baptized Aug. 19, 1689, Mackworth, near  Derby, Derbyshire, Eng.�d.

After moving with his family to London at age 10, Rich�  ardson was apprenticed to a printer before setting up in business for him�  self in 1721. He soon became quite prosperous. In the 1730s he began to  edit and write pamphlets, and he eventually hit on the idea of writing a  book using a series of letters on the same subject. His major novels were  the epistolary novel Pamela (1740), about a servant who avoids seduction  and is rewarded by marriage; and his huge masterpiece, Clarissa, 1 vol.  (1747-48), a tragedy with multiple narrators that develops a profoundly  suggestive interplay of opposed voices. The History of Sir Charles Gran-  dison (1753-54), which blends moral discussion and a comic ending,  influenced later writers, especially Jane Austen.</p><p>Richardson, Tony orig.

He became an adviser to Marie de Medi-  cis in 1616 and later councillor to her son, Louis XIII. Named a cardinal in  1622, he served as chief minister from 1624 and became the controlling  influence in France�s policies. He established royal absolutism in France by  suppressing the political power of the Huguenots and reducing the influ�  ence of the nobles. In foreign policy, he sought to weaken Habsburg control  of Europe and involved France in the Thirty Years' War.

U.S. biologist. He received a Ph.D. from</p><p>Johns Hopkins University. He introduced the concept of the biological  &#x25A0;&#x25A0; clock in a 1927 paper on animals� internal cycles (see biological rhythm).</p><p>He theorized that ancient peoples� discovery of fire changed their habits,  resulting in brain-structure changes that increased their ability to learn and  communicate. He helped discover relationships between behaviour and  biochemistry governing sleep, stress, and disease onset.</p><p>Richter, Gerhard (b. Feb. 9, 1932, Dresden, Ger.) German painter.  Beginning in the early 1960s, Richter created paintings that were faithful  enlargements of black-and-white photographs, often family snapshots and  landscapes; he would continue this pursuit throughout his career. In the  1970s he also created monochromatic paintings, which explored the act  of painting at its purest, while by the 1980s he experimented with an  expressionistic, gestural style. Notably, Richter never allied himself to one  movement�he has been alternatively described as a Pop artist, Minimal�  ist, and postmodernist. Instead, he has consistently carried out a rigorous,  personal exploration of the process of painting.</p><p>Richter, Sviatoslav (Teofilovich) (b. March 20, 1915, Zhitomir,  Ukraine, Russian Empire�d. Aug. 1, 1997, Moscow, Russia) Ukrainian  pianist of German descent. He became accompanist to the Odessa Opera  at age 15 and began conducting there at 18. In 1949, two years after he</p><p>graduated from the Moscow Conservatory, he won the Stalin Prize. He  toured Europe, China, Japan, and the U.S., becoming legendary for the  powerful technique and fiery energy in his solo performances. Highly  regarded as an accompanist and chamber player as well, he made cel�  ebrated trio recordings with Mstislav Rostropovich and David Oistrakh.</p><p>Richter scale Vrik-toiA Widely used measure of the magnitude of an  earthquake, introduced in 1935 by U.S. seismologists Beno Gutenberg  (1889-1960) and Charles F. Richter (1900-1985). The scale is logarith�  mic, so that each increase of one unit represents a 10-fold increase in  magnitude (amplitude of seismic waves). The magnitude is then translated  into energy released. Earthquakes that are fainter than the ones originally  chosen to define magnitude zero are accommodated by using negative  numbers. Though the scale has no theoretical upper limit, the most severe  earthquakes have not exceeded a scale value of 9. The moment magni�  tude scale, in use since 1993, is more accurate for large earthquakes; it  takes into account the amount of fault slippage, the size of the area rup�  tured, and the nature of the materials that faulted.</p><p>Richthofen \'rikt- I ho-f9n\, Manfred, baron von known as the  Red Baron (b.

In  1915 he transferred to the air force  and in 1916 took command of a  fighter group that came to be known  as �Richthofen�s Flying Circus� for  its decorated scarlet planes. He had  been acclaimed Germany�s greatest  aviation ace, credited with shooting  down 80 enemy airplanes, before he  himself was shot down at age 25.</p><p>Ricimer Vri-so-moA orig.

The son of a Visigothic prin�  cess and a Germanic chieftain, he  rose high in the Roman army, but he  was barred from the imperial throne  as a barbarian and instead became a  kingmaker in the empire. He defeated  the Vandals in Sicily and deposed the emperor Avitus for Majorian (457),  who elevated him to consul. In 461 Ricimer deposed and executed Majo�  rian and appointed Libius Severus as Western emperor. The Eastern  emperor later made Anthemius ruler in the West, but Ricimer elevated Oly-  brius (472) and killed Anthemius.</p><p>Rickenbacker, Eddie orig. Edward Rickenbacher (b.

He developed an early interest in auto�  mobiles, and by the time the U.S. entered the war in 1917 he was one of  the country�s top racing drivers. He began army service as a driver and  soon became a fighter pilot. For shooting down 26 enemy airplanes in  World War I, he was awarded the Medal of Honor. He later founded and  directed his own automobile company, and from 1932 he was an execu�  tive with several airlines. As president of Eastern Air Lines from 1938 to  1959, he oversaw its growth into a major corporation.</p><p>rickets or vitamin D deficiency Disease of infancy and childhood  characterized by defective bone growth due to lack of vitamin D. Calcium  phosphate is not properly deposited in the bones, which become soft,  curved, and stunted. Early symptoms include restlessness, profuse sweat�  ing, lack of limb and abdominal-muscle tone, soft skull bones, and devel�  opmental delays. Muscles may cramp and twitch. Without early treatment,  effects may include bowlegs, knock-knees, and beadiness where the ribs  meet the breastbone. A narrow chest and pelvis can later increase sus�  ceptibility to lung diseases and impede childbirth. Treatment is with high-  dose vitamin D supplementation, sunlight, and a balanced diet. Adding  vitamin D to milk has reduced rickets in high-latitude areas where the  skin cannot produce enough.</p><p>Ricketts, Howard T(aylor) (b. Feb. 9, 1871, Findlay, Ohio, U.S.�d.

He found that epidemic typhus in  Mexico was transmitted by a louse and found a related bacterium in the  victim�s blood and in the lice. He transmitted the disease to monkeys,  which developed immunity. He died of typhus later that year.</p><p>rickettsia \ri-'ket-se-3\ Any of the rod-shaped bacteria that make up the  family Rickettsiaceae (named for Howard Ricketts). They are rod-shaped  or variably spherical, and most are gram-negative (see gram stain). Natu�  ral parasites of certain arthropods, they can cause serious diseases in  humans and other animals, to which they are usually transmitted by a bite  from an arthropod carrier. Because certain species can survive consider�  able drying, rickettsias can also be transmitted when arthropod feces are  inhaled or enter the skin through abrasion. Typhus, trench fever, and Rocky  Mountain spotted fever are rickettsial infections. The most effective treat�  ment includes timely and prolonged administration of broad-spectrum  antibiotics.</p><p>Rickey, Branch (Wesley) (b. Dec. 20, 1881, Stockdale, Ohio,  U.S.�d. Dec. 9, 1965, Columbia, Mo.) U.S. baseball executive. Rickey  began playing professional baseball while a student at Ohio Wesleyan  University. In 1917 he began a long association with the St. Louis Car�  dinals (president, 1917-19; field manager, 1919-25; general manager,  1925^12). In 1919 he devised the farm system of training ballplayers. He  later became president and general manager of the Brooklyn Dodgers  (1943-50). Defying strong resistance, in 1945 he broke a long-standing  race barrier by hiring the first black player in major league baseball. Jackie  Robinson played for the Dodgers� farm teams for two years before he was  brought up to play as an infielder for Brooklyn in 1947. Rickey was later  associated with the Pittsburgh Pirates (1950-59).</p><p>Rickover, Hyman G(eorge) (b. Jan. 27, 1900, Makov, Russia�d.

After  graduating from the U.S. Naval Academy, he served on submarines and  other ships, then headed the electrical section of the Navy�s Bureau of  Ships in World War II. From 1947 he led the Navy�s nuclear-propulsion  program; his team developed the first atomic-powered submarine, the  USS Nautilus, launched in 1954. He headed research on reactor develop�  ment for the Atomic Energy Commission and helped develop the coun�  try�s first full-scale, civilian-use nuclear power plant, at Shippingport, Pa.  (1956-57). Promoted to admiral in 1973, he was noted for his outspoken  views and his singleminded advocacy of nuclear power.</p><p>Rida, Muhammad Rashid See Muhammad Rashid Rida</p><p>riddle Deliberately enigmatic or ambiguous question requiring a  thoughtful and often witty answer. The riddle is a form of guessing game  that has been a part of the folklore of most cultures from ancient times.  Western scholars generally recognize two main kinds of riddle: the  descriptive riddle, usually describing an animal, person, plant, or object  in an intentionally enigmatic manner (thus an egg is �a little white house  without door or window�); and the shrewd or witty question. A classical  Greek example of the latter type is �What is the strongest of all things?��  �Love: iron is strong, but the blacksmith is stronger, and love can sub�  due the blacksmith.�</p><p>Ride, Sally (Kristen) (b.

In 1942 he commanded an airborne division in the inva�  sion of Sicily (1943), the first airborne assault in U.S. military history. He  led his paratroopers in the Normandy Campaign and commanded airborne  operations across Europe. In the Korean War he led the U.S. 8th Army,</p><p>rallying UN forces and forcing the Chinese out of South Korea. Promoted  to general, he succeeded Douglas MacArthur as Allied commander in the  Far East (1951).

After forming a production company, she  made and starred in the mystical The Blue Light (1932). For Adolf Hitler she  directed the propaganda film Triumph of the Will (1935), a documentary  glorifying the 1934 Nurnberg rally. She was praised for the technical bril�  liance of Olympia (1938), her documentary on the 1936 Berlin Olympic  Games.

In 1869 Riel headed a revolt against Cana�  dian expansion in the west that resulted in the establishment of the province  of Manitoba (1870). Intermittent hostilities continued for several years  thereafter, and Riel was officially outlawed. In 1885 he led a Metis uprising  in Saskatchewan that was crushed by the Canadians. Riel was found guilty  of treason and hanged. His death led to ethnic conflicts in Quebec and  Ontario and marked the beginning of the nationalist movement.</p><p>Riemann \'re-,man\, (Georg Friedrich) Bernhard (b. Sept. 17,  1826, Breselenz, Hanover�d. July 20, 1866, Selasca, Italy) German  mathematician. He studied at the Universities of Berlin and Gottingen and  later taught principally at Gottingen. His dissertation (1851) was on func�  tion theory. He became convinced that mathematical theory could link  magnetism, light, gravitation, and electricity and suggested field theories,  in which the space surrounding electrical charges may be mathematically  described. While continuing to develop unifying mathematical themes in  the laws of physics, he created Riemannian geometry (or elliptic geometry),  which proved essential to Albert Einstein�s model of space-time in relativity  theory. Riemann surfaces, Riemann integrals, and Riemann curvature,  among other concepts, contributed to the understanding of curves and  surfaces, as well as of calculus. With Carl Friedrich Gauss, Riemann helped  establish Gottingen�s reputation as a world leader in mathematical  research. His work widely influenced geometry and analysis.</p><p>Riemannian geometry See elliptic geometry</p><p>Riemenschneider Vre-mon-  .shni-dorV Tilman (b. c. 1460,  Heilgenstadt or Osterode, Domain of  the Teutonic Order�d.

In 1918 he created his famous  red-and-blue armchair, which, with its emphasis on geometry and use of  primary colours, became a symbol of De Stijl. His masterpiece is the  Schroeder House in Utrecht (1924), remarkable for its interplay of right-  angle forms, planes, and lines, and for its use of primary colours.</p><p>Rif Muslim Berber people who live in El-Rif in northern Morocco. Their  culture is based on cultivation, herding, and fish processing. They speak  a dialect of Berber, but Arabic and Spanish are also widely used. They  have traditionally flouted central-government control and have often insti�  gated uprisings and attempted coups.

For the greater  part of its length, the mountains hug the Mediterranean Sea, leaving only  a few narrow coastal valleys suitable for agriculture or urban settlement.  The loftier peaks are snowcapped in winter. In the 1920s Berber tribes  inhabiting the region rose in revolt under Abd al-Krim to resist Franco-  Spanish occupation.</p><p>rifle Firearm whose barrel is rifled (i.e., has spiral grooves cut inside it  to give a spin to the projectile). Though usually applied to a weapon fired  from the shoulder, the name can also refer to a rifled cannon. Rifled fire�  arms date to at least the 15th century, when it was discovered that impart�  ing a spin to the bullet improved its range and accuracy. The earliest  muzzle-loading rifles were more difficult to load than smoothbore mus�  kets, but the invention of metallic cartridges made possible the develop�  ment of breech-loading mechanisms. Bolt-action rifles, which use a  manually operated cylinder to drive the cartridge into the rifle�s chamber,  are the most common type for hunting. See also assault rifle.</p><p>rift valley Elongated trough formed by the subsidence of a segment of  the Earth�s crust between dip-slip, or normal, faults. Rift valleys are usu�  ally narrow and long and have a relatively flat floor. The sides drop away  steeply in steps and terraces. Rift valleys are found on the continents and  along the crests of oceanic ridges. They occur where two plates that make  up the Earth�s surface are separating (see plate tectonics). Submarine rift  valleys are usually centres of seafloor spreading, where magma wells up  from the mantle. The most extensive continental rift valleys are those of  the East African Rift System; other notable examples include Russia�s  Baikal Rift Valley and Germany�s Rhine Rift Valley.</p><p>Rift Valley See Great Rift Valley</p><p>Riga Vre-g9\ City (pop., 2000 prelim.: 764,328), capital of Latvia. Riga  is situated on both banks of the Western Dvina River, above its mouth on  the Gulf of Riga. It was founded as a trading post in 1201 on the site of  an ancient Liv settlement and joined the Hanseatic League in 1282. In the  Middle Ages it was dominated by the Teutonic Order, and it was  fought over by the Poles and Russians in the 16th century. Riga was cap�  tured by Sweden in 1621 and granted self-government, but it was ceded  to Russia in 1721. The city became the capital of an independent Latvia  from 1918 to 1940 but was thereafter incorporated into the U.S.S.R. Riga  again became the capital of an independent Latvia in 1991. It is a prin�  cipal Baltic port and a major administrative, cultural, and industrial cen�  tre. Its medieval remains include a 13th-century church and a 14th-century  castle.</p><p>Riga, Gulf of Large gulf of the Baltic Sea.

(The name refers to two species considered the �right�  whales to hunt because of their value, slowness, and buoyancy after  death.) The upper jaw is strongly arched, and the lower lip curves upward  along the side, giving the lower jaw a scooplike form. There is no dorsal  fin except in the pygmy right whale ( Caperea marginata), a small,  seldom-seen whale of the Southern Hemisphere. The bowhead whale  (.Balaena mysticetus), inhabiting Arctic and northern temperate waters, is  black, with a white chin, throat, and sometimes underparts. It grows to  about 65 ft (20 m). The northern right whale (E. glacialis) grows to 60 ft  (18 m). Similar to the bowhead but with a smaller, less strongly arched  head, it may also have a �bonnet,� a horny growth infested with parasites,  on its snout.

Rene Maria Rilke (b. Dec. 4,  1875, Prague, Bohemia, Austria-Hungary�d. Dec. 29, 1926, Valmont,  Switz.) Austro-German poet. After an unhappy childhood and an ill-  planned preparatory education, Rilke began a life of wandering that took  him across Europe. His visits to Russia inspired his first serious work, the  long poem cycle The Book of Hours (1905). For 12 years beginning in  1902 his geographic centre was Paris, where he researched a book on  Auguste Rodin, associated with the great sculptor, and developed a new  style of lyrical poetry that attempted to capture the plastic essence of a  physical object; the results were New Poems (1907-08) and its prose  counterpart, the novel The Notebook of Malte Laurids Brigge (1910).  After 13 years of writing very little because of writer�s block and depres�  sion, in 1922 he finally completed the 10 poems of the Duino Elegies  (1923), a profound meditation on the paradoxes of human existence and  one of the century�s poetic masterpieces. Unexpectedly and with aston�  ishing speed, he then composed Sonnets to Orpheus (1923), a superb  55-poem cycle inspired by the death of a young girl, which continues the  Elegies� meditations on death, transcendence, and poetry. The two works  brought him international fame.</p><p>Rimbaud \ra n -'bo\, (Jean-Nicolas-) Arthur (b. Oct. 20, 1854,  Charleville, France�d. Nov. 10,</p><p>1891, Marseille) French poet and  adventurer. The provincial son of an  army captain, he had begun by age  16 to write violent, blasphemous  poems, and he formulated an aes�  thetic doctrine stating that a poet  must become a seer, break down the  restraints and controls on personal�  ity, and thus become the instrument  for the voice of the eternal. He was  invited to Paris by Paul Verlaine, with  whom he had a homosexual relation�  ship and engaged in a wild and dis�  sipated life. The Drunken Boat  (written 1871), perhaps his finest  poem, displays his astonishing ver�  bal virtuosity and a daring choice of  images and metaphors. In Les Illu�  minations (written 1872-74), a col�  lection of mainly prose poems, he  tried to abolish the distinction  between reality and hallucination. A  Season in Hell (1873), which alter�  nates prose passages with dazzling lyrics, became his farewell to poetry</p><p>at age 19. After they had a falling-out, Verlaine shot and wounded Rim�  baud; afterward their final meeting ended in a violent quarrel. Rimbaud  abandoned literature and from 1875 led an international vagabond life as  a merchant and trader, mainly in Ethiopia; he died at age 37 after his leg  was amputated. The Dionysian power of his verse and his liberation of  language from the constraints of form greatly influenced the Symbolist  movement and 20th-century poetry.</p><p>Rimsky-Korsakov, Nikolay (Andreyevich) (b.

While at St. Petersburg�s College of Naval Cadets, he met other  composers; Mily Balakirev took a special interest in him, and from 1867  he was included among the group of nationalist composers known as The  Five. Returning from his first cruise as a midshipman in 1865, he com�  pleted his first symphony. In 1873 he left the naval service and assumed  charge of military bands as inspector and conductor. As the de facto edi�  tor and head of an enterprise dedicated to publishing music by Russian  composers, he edited several posthumous works of Aleksandr Borodin and  Modest Mussorgsky. He wrote many colourful operas, much loved in Rus�  sia, including Sadko (1896), Mozart and Salieri (1897), The Legend of  the Invisible City of Kitezh (1905), and Le Coq d�or (1908); the subjects  of most of these are from Russian or Slavic fairy tales, literature, and his�  tory. Other works include the suite Scheherazade (1888) and the Russian  Easter Festival overture. All his works are distinguished by brilliant  orchestration. His many students included Aleksandr Glazunov, Sergey  Prokofiev, and Igor Stravinsky.</p><p>rinderpest Acute, highly contagious viral disease of ruminants (includ�  ing wild cloven-hoofed ones), common in Africa, the Indian subcontinent,  and the Middle East. The virus spreads by close direct or indirect con�  tact. It is the most severe infectious disease of cattle, with sudden onset  and high mortality; fever and loss of appetite are followed by symptoms  including eye and nasal discharge, laboured breathing, and diarrhea; pros�  tration, coma, and death follow within 6-12 days. Local eradication  depends on controlling it in wild animals and eliminating infected domes�  tic animals; vaccination combined with quarantine is effective.</p><p>ring Circular band of gold, silver, or other precious or decorative mate�  rial usually worn on the finger, but sometimes on the toes, the ears, or the  nose. The earliest examples were found in the tombs of ancient Egypt. In  addition to being worn as adornment, rings have functioned as symbols  of authority, fidelity, or social status. In the early Roman republic, most  were made of iron, gold being reserved for persons of high status; but by  the 3rd century bc anyone except a slave could wear a gold ring. The  Romans are thought to have originated engagement rings, symbolizing a  promise of marriage. In the Middle Ages, signet rings were important in  religious, legal, and commercial transactions; memorial, posy, and keep�  sake rings served sentimental purposes; occult rings supposedly had magi�  cal powers; and poison rings had hollow bezels that could be filled with  poison for the purpose of suicide or homicide.</p><p>ring In modern algebra, a set of elements with two operations, referred  to as �addition� and �multiplication,� that conform to certain conditions.  These specify that the set is closed under both operations, the associative  law holds for both operations, the commutative law holds for addition, the  distributive law holds, there is an additive identity (known as zero), and  every element has an additive inverse (see inverse function). The set of  integers is a ring. See also field theory.</p><p>Ring of Fire Name given to a belt of seismic and volcanic activity  roughly surrounding the Pacific Ocean.

After five of the  seven brothers formed a song-and-  dance troupe (1882), they began to  add circus acts to their show. In 1884  they organized their first small circus  in their hometown, Baraboo, Wis.,  and toured the Midwest in circus  wagons. In 1890 they began moving  their wagons by railway. They  acquired smaller circuses from 1900,  and in 1907 they bought the Barnum  &amp; Bailey Circus, thus becoming the  leading U.S. circus. The guiding  managers were Charles Ringling  (1863-1926) and later John Ringling  (1866-1936), whose acquisition of  American Circus Corp. in 1929  brought 11 major circuses under Rin�  gling control.

Established in 1776  as means of decentralizing rule in the Spanish empire, it controlled an  area previously administered by the Viceroyalty of Peru and included what  is now Argentina, Uruguay, Paraguay, and Bolivia. Successive viceroys  defended the territory against encroachment by Portugal and Britain and  helped Buenos Aires become a flourishing outpost of the Spanish empire.  Salted meat from the cattle ranches of the interior, exported to meet the  demand for cheap food for slaves, brought unprecedented wealth to the  colony.

It rises high in the San Juan Mountains  and flows generally south, passing southeast and forming the entire bor�  der between Texas and Mexico. The earliest European settlements were  along the lower course of the river in the 16th century, but many of the  Pueblo Indian settlements of New Mexico date from before the Spanish  conquest. During the Spanish period, the middle and upper portions were  called the Rio del Norte, and the lower course was called the Rio Bravo.  It is a major source of irrigation.

He moved to Paris in 1947 and, with Paul-Emile Bor-  duas, became associated with the group of Canadian painters known as  Les Automatistes, who practiced automatism. His early lyrical, abstract  paintings evolved into a denser, more powerful impasto style. He is  renowned for his use of various media (including watercolour, ink, oils,  crayon, and chalk), and he also produced large collage murals. He  achieved international acclaim with the huge triptych Pavane (1954) and  is the leading Canadian abstract painter of his generation.</p></section><section><p>rip current or riptide Narrow, jetlike stream of water that flows spo�  radically seaward for several minutes, in a direction perpendicular to a  beach. The term riptide is a misnomer because the currents are in no way  related to tides. Rip currents form at long coasts that are approached by  wave trains that are nearly parallel to the shoreline. In shallow water, nor�  mal wave motion displaces the water small distances shoreward with each  passing wave. During periods of large waves, water builds up at the beach  and cannot escape as longshore currents, which require oblique wave  approach. The buildup continues until water can escape by surging for  several minutes through a low point in a breaker, creating an undertow  that can be dangerous for swimmers.</p><p>riparian right \ri-'par-e-on\ In law, the right of one who owns ripar�  ian land (land abutting or including a stream or river) to have access to  and use of the shore and water.

A mem�  ber of the Transcendental Club and an editor of The Dial , its literary  magazine, he founded the utopian community Brook Farm in 1841 and  served as its director and leading promoter. When it closed in 1847, he  took a job with the New York Tribune to pay off its debts.

Ripple marks are formed in sandy bottoms  by oscillation waves, in which only the wave form advances rapidly, the  actual water-particle motion consisting of almost closed vertical orbits.  The presence of the bottom restricts the lowermost orbits into nearly flat  ellipses, and the bottom water moves back and forth rhythmically. If the  maximum horizontal velocity of this motion is capable of moving the  grains composing the bed, ripple marks develop.

Reforms introduced  by France into its Italian states in the Napoleonic period remained after  the states were restored to their former rulers in 1815 and provided an  impetus for the movement. Secret groups such as Young Italy advocated  Italian unity, and leaders such as Camillo Cavour, who founded the jour�  nal II Risorgimento (1847), Giuseppe Garibaldi, and Giuseppe Mazzini called  for liberal reforms and a united Italy. After the failure of the Revolutions  of 1848, leadership passed to Cavour and Piedmont, which formed an  alliance with France against Austria (1859). The unification of most of  Italy in 1861, followed by the annexation of Venetia (1866) and papal  Rome (1870), marked the end of the Risorgimento.</p><p>Ritalin A mild form of amphetamine used in the treatment of attention-  deficit hyperactivity disorder (ADHD), generic name methylphenidate.

He disbanded the Spanish courts, abolished censorship, and ended  the slave trade. Elected president of the United Provinces in 1826, he  continued to advance reforms but was unable to extricate his country from  a fruitless war with Brazil and was constantly embroiled with provincial  caudillos. Unable to win acceptance for a centralist constitution, he  resigned. His cultural initiatives, including the founding of the University  of Buenos Aires, were among his greatest achievements.

Rivers are a fundamental link in the hydrologic cycle, and  they play a major role in shaping the surface features of the Earth. Even  apparently arid desert regions are greatly influenced by river action when</p><p>periodic floodwaters surge down usually dry watercourses. River flow is  sustained by the difference between water input and output. Rivers are  fed by overland runoff, groundwater seepage, and meltwater released  along the edges of snowfields and glaciers.

Blindness is caused by dead microfilariae�the lar�  vae that can be produced for some 15-18 years by adult worms�inside  the eye. River blindness is common in savannah areas of Africa and in  Guatemala and Mexico.

He briefly espoused Cubism but  abandoned it c. 1917 for a visual language of simplified forms and bold  areas of colour. Returning to Mexico in 1921, he sought to create a new  national art on revolutionary themes in the wake of the Mexican Revolu�  tion. He painted many public murals, the most ambitious of which is in  the National Palace (1929-57). From 1930 to 1934 he worked in the U.S.  His mural for New York�s Rockefeller Center aroused a storm of contro�  versy and was ultimately destroyed because it contained the figure of  Vladimir Ilich Lenin; he later reproduced it at the Palace of Fine Arts in  Mexico City. With Jose Clemente Orozco and David Alfaro Siqueiros, Riv�  era created a revival of fresco painting that became Mexico�s most sig�  nificant contribution to 20th-century art. His large-scale, didactic murals  contain scenes of Mexican history, culture, and industry, with Indians,  peasants, conquistadores, and factory workers drawn as simplified figures  in crowded, shallow spaces.

Like DNA, it consists  of strands of repeating nucleotides joined in chainlike fashion, but the  strands are single (except in certain viruses), and it has the nucleotide  uracil (U) where DNA has thymine (T). Messenger RNA (mRNA), a single  strand copied from a DNA strand that acts as its template, carries the  message of the genetic code from DNA (in chromosomes) to the site of  protein synthesis (on ribosomes). Ribosomal RNA (rRNA), part of the  building blocks of ribosomes, participates in protein synthesis. Transfer  RNA (tRNA), the smallest type, has fewer than 100 nucleotide units  (mRNA and rRNA contain thousands). Each nucleotide triplet on mRNA  specifies which amino acid comes next on the protein being synthesized,  and a tRNA molecule with that triplet�s complement on its protruding end  brings the specified amino acid to the site of synthesis to be linked into  the protein. Various minor types of RNA also exist; at least some act as  catalysts (ribozymes), a function long ascribed only to proteins.</p><p>roach See cockroach</p><p>roach Common European sport fish (Rutilus rutilus) of the carp family  (Cyprinidae), found in lakes and slow rivers.

The earliest roads developed from paths and trails and appeared with the  invention of wheeled vehicles, around 3000 bc. Road systems developed  to facilitate trade in early civilizations; the first major road extended 1,775  mi (2,857 km) from the Persian Gulf to the Aegean Sea and was used c.  3500-300 bc. The Romans used roads to maintain control of their empire,  with over 53,000 mi (85,000 km) of roadways extending across its lands;  Roman construction techniques and design remained the most advanced  until the late 1700s. In the early 19th century invention of macadam road  construction provided a quick and durable method for building roads, and  asphalt and concrete also began to be used. Motorized traffic in the 20th  century led to the limited-access highway, the first of which was a park�  way in New York City (1925). Superhighways also appeared in Italy and  Germany in the 1930s.

Nephew of the chief of the MacGregor clan, he  became a freebooter and apparently engaged in the time-honoured Bor�  der practices of cattle stealing and blackmail. After the penal laws against  the MacGregors were reintroduced (1693), he took the surname Camp�  bell and frequently signed himself Rob Roy (�Red Rob�), in reference to  his red hair. He became a brigand after his financial ruin in 1712 and  exacted tribute for protection against thieves. Arrested in 1722, he was  pardoned in 1727. He was glamorously portrayed as a Scottish Robin  Hood in Walter Scott�s novel Rob Roy.</p><p>Robbe-Grillet \rob-gre-'ya\, Alain (b. Aug. 18, 1922, Brest, France)  French writer. Trained as a statistician and agronomist, he became a writer  and leading theoretician of the nouveau roman (�new novel�), the French  antinovel that emerged in the 1950s. His narratives lack conventional ele�  ments such as chronological plot and are composed largely of recurring  images and repeated fragments of dialogue. Among his works are fiction,  including The Erasers (1953), Jealousy (1957), and Djinn (1981); the  essay �Towards a New Novel� (1963); and the memoir Ghosts in the Mir�  ror (1984).

Born into a family of Norman knights, he</p><p>joined his brothers and half brothers  in southern Italy, defeating the Byz�  antines, Lombards, and papacy  (1053) and taking over Apulia. He  allied with the papacy (1059), agree�  ing to oppose the Byzantines and  expel the Arabs from Sicily. His  brother Roger (later Roger I) helped  him to conquer Sicily and Calabria,  and he gained control of Salerno in  1076, making it the capital of his  duchy. Robert made an abortive  attempt to gain the Byzantine throne  (1083) but returned to Italy to defend  Pope Gregory VII from his enemies.</p><p>Robert I known as Robert the  Bruce (b.

Norman ancestry and held lands in  FR E D FEHL both England and Scotland, he sided</p><p>with the Scots against England and  supported the rebel William Wallace. He gained the Scottish throne in 1306  after stabbing a rival to death in a quarrel. Twice defeated by Edward I  (1306), he became a fugitive, hiding on a remote island off the Irish coast.  Within a year, Robert returned to Scotland and began gathering supporters,  and in 1314 he defeated Edward II at the Battle of Bannockburn. Edward III  finally recognized him and confirmed Scottish independence in 1328.</p><p>Robert II known as Robert Curthose \'kur-toz\ (b. c. 1054�d.

Robert was exiled to Italy but returned as duke on his  father�s death. He pawned Normandy to his brother William II and joined  the First Crusade, in which he fought bravely and helped capture Jerus�  alem (1099). He led an unsuccessful invasion of England after Henry I  became king (1100); Henry then invaded Normandy (1105-06) and cap�  tured Robert, who spent the rest of his life as a prisoner.</p><p>Robert II (b.

Grandson of Robert I, he served as  regent during the periods of exile and of imprisonment by the English of  his uncle, David II, and took the throne on David�s death in 1371 as the  first Stuart king and thus was the founder of the house of Stuart. His reign  proved anticlimactic; he had little effect on political and military affairs,  taking no active part in the renewed war with England (1378-88). Suc�  cession after his death was disputed by his numerous children (legitimate  and illegitimate) and their descendants.</p><p>Robert III orig. John Stewart, earl of Carrick (b. c. 1337�d.

Physically dis�  abled by a kick from a horse in 1388, he was never the real ruler of Scot�  land. His brother Robert, earl of Fife, later duke of Albany, governed  during Robert II�s last years and continued to govern throughout Robert  Ill�s reign, except for three years when Robert Ill�s eldest son, David,  duke of Rothesay, took his place.

Trained as a watchmaker, he became a magician at the Palais-  Royal (1845-55), performing on a bare stage in evening dress rather than  the usual wizardlike costume. He used familiar objects to create his illu�  sions, then gave a plausible explanation of the technical procedures  involved. Robert-Houdin was the first magician to use electricity, and he  exposed magicians who relied on supernatural explanations for their feats.  In 1856 he was sent to Algeria by the French government to counter the  influence of the dervishes, who were encouraging rebellion against French  forces, by duplicating their feats.</p><p>Roberts, Sir Charles G(eorge) D(ouglas) (b.

Rehnquist, who later became chief justice. He held  several positions in the administrations of Presidents Ronald Reagan and  George H.W. Bush, during which time he became noted for his apparent  advocacy of strongly conservative legal viewpoints. In 2003 Pres. George  W. Bush nominated Roberts to the U.S. Court of Appeals for the District  of Columbia Circuit; he was confirmed later that year. He held that post  until 2005, when Bush nominated him to fill the vacancy left by the retir�  ing justice Sandra Day O'Connor. Shortly before Roberts�s confirmation  hearings began, Rehnquist died, prompting Bush to appoint Roberts chief  justice. Quickly confirmed by the Senate (78-22), he was sworn in on  Sept. 29, 2005.</p><p>Roberts, Oral (b. Jan. 24, 1918, near Ada, Okla., U.S.) U.S. evange�  list.

He spent 12 years as a pastor in several towns in the South  and built up his own organization, the Pentecostal Holiness Church. He  studied at Oklahoma Baptist College (1943-45), emerging as a Method�  ist. Claiming direct communications from God, he began an itinerant  ministry of faith healing in the late 1940s. The Oral Roberts Evangelistic  Association, based in Tulsa, Okla., became the parent organization for  other endeavors, including a publishing firm, and Roberts became known  for his luxurious way of life. From the 1950s he reached wide audiences  through radio and television. In 1963 he founded Oral Roberts Univer�  sity in Tulsa, and in the early 21st century he continued his association  with the university, holding the office of chancellor.</p><p>Roberts, Richard (b.

He was one  of the inventors of the metal planer, and he made important improvements  to the lathe. His automatic spinning mule marked an important advance in  spinning technology. He developed a screw-cutting lathe and built gear�  cutting and slotting machines, railway locomotives with interchangeable  parts, automatic machinery for punching holes in plate, and the first suc�  cessful gas meter. Though he was said to have improved everything he  touched, he was not a shrewd businessman, and he died in poverty.</p><p>Robertson, Oscar (Palmer) (b.

Born to a former slave turned preacher and a Quaker mother, Robeson  attended Rutgers University, where he was an All-America football player.  Graduating at the head of his class, he went on to earn a law degree at  Columbia University. Because of a lack of opportunity for African Ameri�  cans in law, he turned to theatre, joining a group that included Eugene  O'Neill and appearing in his All God�s Chillun Got Wings (1924) and The  Emperor Jones (1924), a huge success in New York City and London. He  also starred in the film version of The Emperor Jones (1933). Robeson�s  superb bass-baritone brought him worldwide renown with his perfor�  mance of �OF Man River� in Show Boat (1928). His lead role in Othello  won high praise in London (1930) and on Broadway (1943). He visited  the Soviet Union in 1934 and became identified with leftist politics. In  1950 his passport was withdrawn because he refused to disclaim mem�  bership in the Communist Party. Viciously harassed and ostracized, Robe�  son left the U.S. to live in Europe and travel in Soviet-bloc countries, but  he returned in 1963 because of ill health.</p><p>Robeson Vrob-S3n\ Channel Northernmost part of the sea passage  connecting Baffin Bay with the Arctic Ocean.

He became a leading  member of the Montagnards in the National Convention. After calling  for the death of Louis XVI, he led the Jacobins (see Jacobin Club) and the  Committee of Public Safety (1793) in establishing the Reign of Terror, dur�  ing which, as virtual dictator of France, he had former friends such as  Georges Danton executed. Despite earlier support from the people of  Paris, who called him �the Incorruptible,� he lost his dominating author�  ity and was overthrown and guillotined in the Thermidorian Reaction. Often  regarded as a bloodthirsty dictator, he was later valued for his social ide�  als of reducing inequality and ensuring work for all.</p><p>robin Either of two thrush species (family Turdidae).

The hero of ballads dating  from as early as the 14th century, Robin Hood was a rebel who robbed  and killed landowners and government officials and gave his gains to the  poor. He treated women and common people with courtesy, and he  ignored the laws of the forest that restricted hunting rights. His greatest  enemy was the sheriff of Nottingham. The ballads emerged during a time  of agrarian unrest that culminated in the Peasants' Revolt of 1381. There  is no evidence of Robin Hood�s historical existence, though later tradi�  tion places him in the reign of King John. In postmedieval ballads and  stories he was a nobleman who took refuge in Sherwood Forest after los�  ing his lands. His men included Little John and Friar Tuck; his beloved  was Maid Marion.</p><p>Robinson, Bill orig. Luther Robinson known as Bojangles (b.</p><p>May 25, 1878, Richmond, Va., U.S.�d.

He developed extraordinary tap-dancing skills as a child,  became the first black performer to appear in white vaudeville shows, and  was later the first black in Florenz Ziegfeld�s Follies. He is best known for  his starring roles in films, notably the four he made with Shirley Temple and  the all-black musical Stormy Weather (1943). His soft-shoe and tap rou�  tines were widely copied by other dancers, but he was unmatched for  ingenuity in creating new steps, especially his famous �stair dance.� He  also was famed for a unique ability to run backward.

He  played baseball with the Kansas City  Monarchs of the Negro leagues  before being signed by Branch Rickey  to a Brooklyn Dodgers farm team  (1945�46). On being advanced to the  majors in 1947, he endured with  notable dignity the early opposition  to his presence, opposition quickly  silenced by Robinson�s immediate  success as he led the league in stolen  bases and was chosen Rookie of the  Year. In 1949 he won the batting  championship with a .342 average  and was voted the league�s most valuable player. He retired from the Dodg�  ers team in 1956 with a career batting average of .311.

His outstanding abil�  ity and flamboyant personality made him a hero of boxing fans through�  out the world, and he is sometimes considered the best fighter in history.</p><p>robot Any automatically operated machine that replaces human effort,  though it may not look much like a human being or function v in a human�  like manner. The term comes from the play R.U.R. by Karel Capek (1920).  Major developments in microelectronics and computer technology since  the 1960s have led to significant advances in robotics. Advanced, high-  performance robots are used today in automobile manufacturing and air�  craft assembly, and electronics firms use robotic devices together with  other computerized instruments to sort or test finished products.</p><p>robotics Design, construction, and use of machines (robots) to perform  tasks done traditionally by human beings. Robots are widely used in such  industries as automobile manufacture to perform simple repetitive tasks,  and in industries where work must be performed in environments haz�  ardous to humans. Many aspects of robotics involve artificial intelligence;  robots may be equipped with the equivalent of human senses such as  vision, touch, and the ability to sense temperature. Some are even capable  of simple decision making, and current robotics research is geared toward  devising robots with a degree of self-sufficiency that will permit mobility  and decision-making in an unstructured environment. Today�s industrial  robots do not resemble human beings; a robot in human form is called  an android.</p><p>Roca Vro-koV, Cape Promontory in Portugal.

He was put in com�  mand of a French army of 6,000 sent to join the Continental Army in the  American Revolution (1780). After waiting in vain for French naval sup�  port, he joined forces with George Washington at White Plains, N.Y., in  1781.

June 14, 1922, Dublin, Ire.) Irish-  born U.S. architect. After studying under Ludwig Mies van der Rohe, he  became Eero Saarinen�s principal design associate. After Saarinen�s death  in 1961, Roche and John Dinkeloo (1918-81) completed Saarinen�s  unfinished projects, including the Dulles International Airport Terminal  Building, near Washington, D.C. (1962), and St. Louis�s Gateway Arch  (1965). The two launched their own firm in 1966; their approach, though  similar to Saarinen�s, resulted in simpler geometric forms. Well-known  works by Roche and Dinkeloo include the Ford Foundation headquarters  in New York City (1968), General Foods headquarters in Rye, N.Y.  (1977), and the Bouygues world headquarters outside Paris (1983).

It was  the home of Margaret and Kate Fox, spiritualists who attracted world  attention in the 1840s with their seances known as the �Rochester rap-  pings.� Frederick Douglass published his antislavery newspaper there in  1847, and the city was a terminus of the Underground Railroad. Susan B.  Anthony lived there (1866-1906). In the 1890s George Eastman devel�  oped photographic equipment there; the city�s manufacturing still includes  cameras and photographic equipment. It is a cultural and educational cen�  tre and the home of the University of Rochester, the Eastman School of  Music, and the Rochester Institute of Technology.</p><p>Rochester, John Wilmot, 2nd earl of (b.

The most notorious debauchee of the  Restoration court, Rochester was also its best poet and one of the most  original and powerful English satirists. A Satyr Against Mankind (1675)  is a scathing denunciation of rationalism and optimism that contrasts  human perfidy with animal wisdom, and �History of Insipids� (1676) is  a devastating attack on the government of Charles II.

The ancient  animals, tools, and human activities depicted often help shed light on daily  life in the distant past, though the images are frequently symbolic. Some�  times a single site may have art that dates from several centuries. Rock  art may have played a role in prehistoric religion, possibly in connection  with ancient myths or the activities of shamans.

A rock glacier may be 100 ft (30 m) deep and nearly a mile (1.5 km)  long.</p><p>rock music or rock and roll Musical style that arose in the U.S. in the  mid-1950s and became the dominant form of popular music in the world.  Though rock has used a wide variety of instruments, its basic elements are  one or several vocalists, heavily amplified electric guitars (including bass,  rhythm, and lead), and drums. It began as a simple style, relying on heavy,  dance-oriented rhythms, uncomplicated melodies and harmonies, and lyr�  ics sympathetic to its teenage audience�s concerns�young love, the  stresses of adolescence, and automobiles. Its roots lay principally in rhythm  and blues (R&amp;B) and country music. Both R&amp;B and country existed outside  the mainstream of popular music in the early 1950s, when the Cleveland  disc jockey Alan Freed (1921-65) and others began programming R&amp;B,  which until then had been played only to black audiences. Freed�s success  gave currency to the term rock and roll. The highly rhythmic, sensual music  of Chuck Berry, Bill Haley and the Comets, and particularly Elvis Presley in  1955-56 struck a responsive chord in the newly affluent postwar teenagers.  In the 1960s several influences combined to lift rock out of what had  already declined into a bland and mechanical format. In England, where  rock�s development had been slow, the Beatles and the Rolling Stones were  found to have retained the freshness of its very early years and achieved  enormous success in the U.S., where a new generation had grown up  unaware of the musical influences of the new stars. At the same time, Bob  Dylan, Joni Mitchell, the Byrds, and others were blending the traditional bal�  lads and verse forms of folk music with rock, and musicians began to explore  social and political themes. Performers such as the Grateful Dead, Jim Mor�  rison of the Doors, and Frank Zappa of the Mothers of Invention combined  imaginative lyrics with instrumental virtuosity, typically featuring lengthy  solo improvisation. Janis Joplin and Jimi Hendrix won large followings with  their exotic elaborations on R&amp;B. The 1970s saw the rise of singer-  songwriters such as Paul Simon, Neil Young, Elton John, David Bowie, and  Bruce Springsteen, and rock assimilated other forms to produce JAZZ-rock,  heavy metal, and punk rock. In the 1980s the Disco-influenced rock of  Madonna, Michael Jackson, and Prince was balanced by the post-punk �new  wave� music of performers such as Laurie Anderson, Talking Heads (led by  David Byrne), and the Eurythmics�all of whom illustrated their songs with  music videos. By the 1990s rock music had incorporated grunge, rap,  techno, and other forms.</p><p>Rock crystal from the Dauphine region  of France.</p><p>EMIL JAVORSKY-EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Rock River &#x25BA; Rocky Mountains I 1631</p><p>Rock River River, north-central U.S. It rises in southeastern Wisconsin  and flows across the northwestern comer of Illinois, emptying into the  Mississippi River at Rock Island, Ill.; it is 300 mi (480 km) long.

He moved with his family to Cleveland, Ohio, in 1853, and  in 1859 he established a commission business dealing in hay, grain, meats,  and other goods. In 1863 he built an oil refinery that soon was the largest  in the area. With a few associates he incorporated Standard Oil Co. (Ohio)  in 1870. He bought out competitors to control the oil-refinery business in  Cleveland (1872) and in the U.S. (1882). He placed the stock of the com�  pany and its affiliates in other states under control of a board of trustees,  establishing the first major U.S. business trust company. As a result of  antitrust proceedings, he later converted the trust into a holding company.  In the 1890s he turned his attention to philanthropy. He founded the Uni�  versity of Chicago in 1892, the Rockefeller Institute for Medical Research  (later Rockefeller University) in 1901, and the Rockefeller Foundation in  1913. He donated over $500 million in his lifetime, and his philanthropy  continued through donations by his son, John D.

From 1916  to 1963 he produced 317 covers for The Saturday Evening Post. Most of  his works are humorous treatments of idealized small-town and family  life. During World War II, posters of his Four Freedoms were distributed  by the Office of War Information. Though loved by the public, Rockwell�s  work was often dismissed by critics. Late in his career, he turned to more  serious subjects (e.g., a series on racism for Look magazine) and began  to receive more serious attention, and in the 1990s his critical reputation  enjoyed a positive reassessment.</p><p>Rocky Mountain goat See mountain goat</p><p>Rocky Mountain National Park National park, north-central  Colorado, U.S. Established in 1915 and enclosing part of the Front Range  of the Rocky Mountains, the park has an area of 262,191 acres (106,105  hectares).

The word Rococo is derived  from French rocaille, denoting the shell-covered rockwork used to deco�  rate artificial grottoes. Reacting against the ponderous Baroque that had  become the official style of Louis XIV�s reign, the Rococo was light,  elegant, and elaborately ornamented. Several interior designers, painters,  and engravers�among them Pierre Le Pautre, Juste-Aurele Meissonier,  Jean Berain, and Nicolas Pineau�developed a lighter and more intimate  style of decoration for the new residences of nobles in Paris, and the style  was disseminated throughout France by means of engravings. In these  designers� work, walls, ceilings, and moldings feature interlacings of  curves and countercurves based on S and C shapes as well as on shell  forms and other natural shapes. Chinese motifs were also employed (see  chinoiserie). Rococo painting was characterized by easygoing treatments  of mythological and courtship themes, delicate brushwork, and sensuous  colouring; notable practitioners included Antoine Watteau, Francois  Boucher, and Jean-Honore Fragonard. The Rococo style spread through�  out France and other countries, principally Germany and Austria. Among  the finest German examples of Rococo architecture is the church designed  by Balthasar Neumann at Vierzehnheiligen, near Lichtenfels, in Bavaria.  In Italy the Rococo style was concentrated primarily in Venice, where it  was epitomized by the large-scale decorative paintings of Giovanni Bat�  tista Tiepolo.</p><p>Rodchenko Vrad-'cheq-koV Aleksandr (Mikhailovich) (b.

He ini�  tially embraced a completely abstract, highly geometric style, using a ruler  and compass. His series of black-on-black geometric paintings (1918) was  a direct response to Kazimir Malevich�s painting White on White. In 1919,  influenced by Vladimir Tatlin, he began to make hanging three-dimensional  constructions that were, in effect, mobiles. As leader of a wing of Con�  structivism that sought to produce works appropriate to workers� daily  lives, he renounced easel painting and took up photography and book,  furniture, and set design. His innovations in lighting in his photography  influenced Sergei Eisenstein. He returned to easel painting in the 1930s.</p><p>Roddenberry, Gene in full Eugene Wesley Roddenberry (b.</p><p>Aug. 19, 1921, El Paso, Texas, U.S.�d. Oct. 24, 1991, Santa Monica,  Calif.)

Rodgers studied at Columbia  University, where he met his future collaborator Lorenz Hart, and he later  studied composition at the Institute of Musical Art. His first success with  Hart (who wrote lyrics) was a revue, The Garrick Gaieties (1925). Their  comedy On Your Toes (1936), with the jazz ballet Slaughter on Tenth  Avenue, established serious dance as a permanent part of musical com�  edy. Among their other collaborations were Babes in Arms (1937), The  Boys from Syracuse (1938), and Pal Joey (1940), which was revived in  1952 with great success. After Hart�s death, Rodgers worked with libret�  tist Oscar Hammerstein. Their Oklahoma! (1943, Pulitzer Prize) enjoyed a  then-unprecedented Broadway run of 2,248 performances; their 17-year  partnership produced successes such as South Pacific (1949), The King  and I (1951), and The Sound of Music (1959) and made them the fore�  most team in the history of the American musical.</p><p>Rodin \ro-'da n \, (Francois-) Auguste (Rene) (b. Nov. 12, 1840,  Paris, France�d. Nov. 17, 1917, Meudon) French sculptor. Insolvent and  repeatedly rejected by the Ecole des Beaux-Arts, he earned his living by  doing decorative stonework. Not until his late 30s, after a trip to Italy, did  he develop a personal style free of academic restraints and establish his  reputation as a sculptor with The Age of Bronze (exhibited 1878), whose  realism was so great that he was accused of forming its mold on a living  person. His Gates of Hell, a bronze door commissioned in 1880 for a pro�  posed Musee des Arts Decoratifs, remained unfinished at his death, but two  of its many figures were the bases of his most famous images, The Thinker  (1880) and The Kiss (1886). His portraits include monumental figures of  Victor Hugo and Honore de Balzac. Though these and many other works  caused controversy for their unconventionality, he was successful enough  that he could establish a workshop where he executed only molds, leaving  the casting of bronze and the carving of marble to assistants. To his sculp�  ture he added book illustrations, etchings, and numerous drawings, mostly  of female nudes. He revitalized sculpture as an art of personal expression  and has been considered one of its greatest portraitists.</p><p>Rodney, Caesar (b. Oct. 7, 1728, Dover, Del.�d.

Wade (1973) Decision of the Supreme Court of the United States  that established a woman�s right to have an abortion without undue inter�  ference from the government. A Texas law prohibiting abortions was chal�  lenged by an unmarried pregnant woman (pseudonymously named Jane  Roe), and the court ruled in her favour, finding that the state had violated  her right to privacy (see rights of privacy). Harry Blackmun, writing for the  seven-member majority, argued that the state�s legitimate concern for the  protection of prenatal life increased as a pregnancy advanced. While allow�  ing that the state might forbid abortions during a pregnancy�s third trimes�  ter, he held that a woman was entitled to obtain an abortion freely, after  medical consultation, during the first trimester and in an authorized clinic  during the second trimester. The Roe decision, perhaps the most contro�  versial in the Supreme Court�s history, remains at the centre of the issue of  abortion rights. Repeated challenges since 1973, such as Planned Parent�  hood of Southeastern Pennsylvania v. Casey, have narrowed the scope of  Roe but have not overturned it.</p><p>Roebling \'roeb-liq,\ English Vro-bliqV, John Augustus (b. June 12,  1806, Miihlhausen, Prussia�d. July 22, 1869, Brooklyn Heights, N.Y.,  U.S.) German-U.S. civil engineer, a pioneer in the design of suspension  bridges. He immigrated to the U.S. in 1831. His best-known work is New  York�s Brooklyn Bridge. In the 1850s and �60s Roebling and his son Wash�  ington (1837-1926) built four suspension bridges: two at Pittsburgh, one  at Niagara Falls (1855), and one at Cincinnati (1866). When his design  for a bridge connecting Brooklyn and Manhattan was accepted, he was  appointed chief engineer. He died from an injury he received as construc�  tion began. Washington completed the project in 1883; himself incapaci�  tated from 1872 by decompression sickness, his completion of the work  depended heavily on his wife, Emily Warren Roebling.</p><p>Roentgen Vroent-gonV Abraham (b. 1711, Miihlheim, Cologne�d.  1793, Neuwied?, Trier) German furniture designer and cabinetmaker. In  1750 he established a shop in Neuwied, near Cologne. The Rococo-style  furniture he produced there was of outstanding quality and was often  decorated with inlay work of ivory and other semiprecious materials.  Much of his work was created for various German courts. His son David  Roentgen (1743-1807), who succeeded him as head of the firm in 1772,  was appointed cabinetmaker to Marie-Antoinette of France. The Roent�  gens� shop was perhaps the most successful firm of furniture production  in the 18th century.</p><p>Roentgen, Wilhelm Conrad See Wilhelm Conrad Rontgen</p><p>Roethke \'ret-ke\, Theodore (b.

He was crowned king by the antipope  Anacletus II, and he forced Innocent II to confirm him in 1139. He built  a powerful navy but refused to join the Second Crusade, preferring as the  ruler of a largely Arab population to show tolerance toward Muslims. He  promulgated a law code (1140), and his court was an intellectual center  for both Arab and Western scholars.</p><p>Rogers, Carl R(ansom) (b. Jan. 8, 1902, Oak Park, Ill., U.S.�d.

At age  14 he went to Paris to study and found a society in spiritual disarray, and  his life and writings came to reflect his concern with major social, politi�  cal, and spiritual events. From 1910 he taught music history at the Sor-  bonne. His best-known novel is Jean-Christophe (1904-12), a 10-volume  epic whose protagonist is modeled half on Ludwig van Beethoven and half  on himself. His pamphlet Above the Battle (1915) calls on France and  Germany to respect truth and humanity during World War I. In the 1920s  he turned to interpreting the mystical philosophy of Asia, especially India,  in works such as Mahatma Gandhi (1924).

Like a ball bearing, a roller bearing has  two grooved tracks, but the balls are replaced by rollers. The rollers may  be cylinders or shortened cones. If the rollers are cylindrical, only radial  loads (perpendicular to the axis of rotation) can be carried, but with coni�  cal rollers both radial and thrust, or axial, loads (parallel to the axis of  rotation) can be carried. In a given space, a roller bearing can carry a  greater radial load than a ball bearing can.</p><p>roller-skating Recreation and sport in which the participants use roller  skates (shoes with sets of wheels attached) to move about on special rinks  or paved surfaces. The invention of roller skates is traditionally credited  to the Belgian Joseph Merlin in the 1760s, but the first practical four-  wheel skate was designed in 1863 by James Plimpton of Medford, Mass.  Roller-skating speed events became popular in the early 20th century.  Later, team competitions in �roller derbies� on banked tracks became a  spectator sport. Other roller-skate contests, such as acrobatics and hockey,  followed. In the late 20th century, roller skates gave way to in-line (Roll-  erblade) skates, in which a single row of wheels is used in place of the  standard rectangular configuration.</p><p>Rolle's theorem \Tolz\ Special case of the mean-value theorem of dif�  ferential calculus.

Rolling is the most widely used method of shaping metals and is particu�  larly important in the manufacture of steel. The process consists of pass�  ing the metal between pairs of rollers revolving at the same speed but in  opposite directions and spaced so that the distance between them is  slightly less than the thickness of the metal.</p><p>Rolling Stones British musical group. Its original members were Mick  Jagger (b. 1943), Keith Richards (b. 1943), Brian Jones (1944-69), Bill  Wyman (b. 1936), and Charlie Watts (b. 1941). The band was formed in  1962 when Jagger, Richards, and Jones, who had been performing spo�  radically in a blues band, recruited Wyman and formed their own group.  Watts joined the band in 1963. Jagger was the lead vocalist, while Jones  and Richards played guitars, Wyman played bass, and Watts played  drums. The band�s name was adopted from a Muddy Waters song. By 1966  a series of outstanding songs had made the band second in popularity only  to the Beatles. Jagger and Richards wrote most of its songs, which are  marked by a driving backbeat, biting and satirical lyrics, and simple but  expressive instrumental accompaniments. The group reached the height  of its popularity with albums such as Beggar�s Banquet (1968) and Exile  on Main Street (1972). Jones was succeeded by Mick Taylor (b. 1948) in  1969, who was replaced in turn by Ron Wood (b. 1947) in 1976. They  continued to perform long after the other classic rock bands of the 1960s  disbanded.</p><p>Rollins, Sonny orig. Theodore Walter Rollins (b.

Rollins was  inspired by Coleman Hawkins and Charlie Parker and performed with many  musicians in the late 1940s, including Miles Davis. A member of the Clifford  Brown-Max Roach quintet in 1955-57, he later formed his own groups.  Rollins�s robust tone and technical dexterity are matched with athletic  endurance in the service of the logical evolution of ideas in his solos.</p><p>Rollo (b. c. 860�d. c. 932) Scandinavian rover who founded the duchy  of Normandy. After raiding Scotland, England, Flanders, and France on  pirating expeditions, he took lands along the Seine River as his base (c.  911). He battled Charles III of France, who gave him, in return for Rol�  lo�s promise to stop pillaging, the part of Neustria that came to be called  Normandy.</p><p>Rolls-Royce PLC British manufacturer of aircraft engines and propul�  sion and power systems and, for much of the 20th century, a maker of  luxury automobiles. Charles S. Rolls, a pioneer motorist and aviator, and  Henry Royce, an engineer and carmaker, incorporated Rolls-Royce Ltd.  in 1906. The firm�s handsome, immaculately engineered cars included the  Silver Ghost (introduced 1906 as �40/50 hp� model), a series of Phan�  toms (1925), the Silver Dawn (1949), Silver Cloud (1955), Silver Shadow  (1965), and Silver Seraph (1998). In 1931 Rolls-Royce acquired Bentley</p><p>Motors Ltd., another maker of fine cars. Rolls-Royce also developed a  series of notable piston and jet aircraft engines, beginning with the Eagle  (1914); eventually its turbine-engine operations accounted for the largest  part of its sales. A fixed-price contract with Lockheed Aircraft (see Lock�  heed Martin Corp.) to produce an engine for its L-1011 TriStar jetliner  drove Rolls-Royce into bankruptcy in 1971. It was split into two compa�  nies; its jet-engine division was taken over by the British government and  later privatized as Rolls-Royce PLC, while its automobile operations were  restructured into Rolls-Royce Motor Holdings Ltd. and privatized. The  latter was acquired in 1980 by Vickers Ltd., which sold it to Volkswagen  AG in 1998 as part of a novel agreement in which BMW AG would take  over the manufacture of cars with the Rolls-Royce name in 2003, while  Volkswagen retained the Bentley line.</p><p>Rolvaag Vrol-.vagV Ole (Edvart) (b.

He immigrated to the U.S. in 1896 and  spent most of his life at St. Olaf College (Northfield, Minn.), teaching  Norwegian language and literature and the history of Norwegian immi�  gration. His works, written in Norwegian, are noted for their realistic por�  trayals of Norwegian settlers on the Dakota prairies and of the clash  between transplanted and native cultures in the U.S. His best-known work  is Giants in the Earth (1927), a translation of two of his novels.</p><p>ROM \'ram\ in full read-only memory Form of computer memory  that does not lose its contents when the power supply is cut off and that  is not rewritable once it is manufactured or written.

See also  CD-ROM, COMPACT DISC.</p><p>Rom or Gypsy plural Roma Any member of a people originating in  northern India but now living worldwide, principally in Europe. Most  speak Romany in addition to the local language. It is thought that Roma  groups left India in successive migrations, reaching western Europe by  the 15th century. In the 20th century they spread to North and South  America and Australia. Because of their often nomadic and marginalized  lives, population figures are largely guesswork; estimates in the early 21st  century range from two to three million. They have often been persecuted  and harassed; the Nazis killed about 400,000 Roma in extermination  camps. How many Roma retain a nomadic lifestyle is unclear, but those  that migrate do so at least seasonally along patterned routes that ignore  national boundaries. They pursue occupations compatible with a nomadic  life. In the past they were often livestock traders, tinkers, fortune-tellers,  and entertainers; today they are often car mechanics, auto-body repair�  men, and workers in traveling circuses and amusement parks. Confed�  erations of 10-100 families elect chieftains for life, but their title is not  heritable. Women are organized as a group within the confederation and  represented by a senior woman.

Louis-Henri-Jean Farigoule (b.</p><p>Aug. 26, 1885, Saint-Julien-Chapteuil, France�d. Aug. 14, 1972, Paris)  French novelist, dramatist, and poet. A teacher of philosophy, Romains  first became known as a poet and as founder (c. 1908-11), with Georges  Chenneviere, of the literary movement Unanimisme, which combined  belief in universal brotherhood with the psychological concept of group  consciousness. His most popular work was the comedy Knock (1923), a  satire on doctors. His masterpiece, Men of Good Will, 27 vol. (1932-46),  is a vast novel cycle attempting to recreate the spirit of French society  from 1908 to 1933 and exemplifying the Unanimiste interest in collec�  tive life.</p><p>roman Typeface used most widely in Western typography, the general  term for the type of this book�s text. Characterized by simple, unembel�  lished shapes, roman was developed by 15th-century printers as an alter�  native to the heavy-bodied, spiky black letter script. Models for a new type  that was easier to cut and read were found in the scriptoria, where scribes,  probably at the urging of humanist scholars, were experimenting with a  letter face they believed had been used in ancient Rome. Historians now  trace its ancestry instead to the letter forms developed for Charlemagne�s  decrees by Alcuin in the 9th century. Within a century, roman had super�  seded all other typefaces throughout Europe; the sole exception was Ger�  many, where black letter continued to hold sway into the 20th century.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1636 I roman a clef &#x25BA; Roman religion</p><p>roman a clef \ro-man-a-'kla\ French "novel with a key" Novel  that has the extraliterary interest of portraying identifiable people more or  less thinly disguised as fictional characters. The tradition dates to 17th-  century France, when members of aristocratic literary coteries included  in their historical romances representations of well-known figures in the  court of Louis XIV. A more recent example is W. Somerset Maugham�s  Cakes and Ale (1930), widely held to portray Thomas Hardy and Hugh  Walpole. A more common type of roman a clef is one in which the dis�  guised characters are easily recognized only by a few insiders, as in Simone  de Beauvoir�s The Mandarins (1954).</p><p>Roman Africa See Roman Africa  Roman alphabet See Latin alphabet</p><p>Roman Catholicism Largest denomination of Christianity, with more  than one billion members. The Roman Catholic Church has had a pro�  found effect on the development of Western civilization and has been  responsible for introducing Christianity in many parts of the world. It  regards itself as the only legitimate inheritor of the ministry of Jesus, by  virtue of an unbroken succession of leaders beginning with St. Peter the  Apostle and continuing to the present day. It holds that the pope is the  infallible interpreter of divine revelation. Church organization is strictly  hierarchical. The pope appoints and presides over the cardinals, whose  numbers grew dramatically in the late 20th century, reaching 182 under  John Paul II (1978-2005). Each of the church�s 500 archbishops is the head  of an archdiocese. These in turn are divided into about 1,800 dioceses,  each headed by a bishop. Within dioceses are parishes, each served by a  church and a priest. Only men can enter the priesthood, but women who  wish to enter holy orders can become nuns, who are organized into orders  and convents. The basic form of worship is the mass, which celebrates the  sacrament of the Eucharist. Theologically, Roman Catholicism differs from  Protestantism with regard to its understanding of the sources of revelation  and the channels of grace. With Eastern Orthodoxy it asserts that both  scripture and church tradition are revelatory of the basis of Christian belief  and church polity. It sets the number of sacraments at seven (baptism, rec�  onciliation [formerly known as penance], the Eucharist, matrimony, ordi�  nation, confirmation, and anointing of the sick); its rich sacramental life  is supplemented by other devotions, chiefly eucharistic services and devo�  tions to the saints. The Second Vatican Council (1962-65) promoted the  role of the laity in the church, approved the use of the vernacular in the  mass, and strove to improve relations with other religions. Pope John Paul  II actively pursued better relations with other faiths, especially Judaism,  and remained popular despite various controversies. Although faced with  many challenges, the church remained one of the largest and most sig�  nificant religious bodies in the world at the start of its third millennium.</p><p>Roman Curia Group of Vatican bureaus that assist the pope in exer�  cising his jurisdiction over the Roman Catholic Church. The work of the  Curia is traditionally associated with the College of Cardinals. A cardinal  named as secretary of state coordinates the activities of the Curia, and  various sacred congregations handle administrative matters�for  example, the Sacred Congregation for the Causes of Saints is concerned  with beatification and canonization and with the preservation of relics.  The judicial branch of the Curia consists of three tribunals, of which the  highest is the Apostolic Signatura.</p><p>Roman de la Rose \r6- , ma n -d3-la- , ros\ French "Romance of the</p><p>Rose" One of the most popular French poems of the late medieval  period. Modeled on Ovid�s Art of Love, it survives in more than 300  manuscripts. Its first 4,058 lines were written c. 1225-30 by Guillaume  de Lorris; they form a charming dream allegory drawing on traditions of  courtly love. About 1280 Jean de Meun wrote the rest of the more than  21,000 lines, incorporating a vast mass of encyclopaedic information and  opinions on many contemporary topics, which secured the poem�s fame.  The Roman was translated by Geoffrey Chaucer and was one of the most  important literary influences on his writings.</p><p>Roman law Law of the Roman Republic and Empire. Roman law has  influenced the development of law in most of Western civilization. It dealt  with matters of succession (or inheritance), obligations (including con�  tracts), property (including slaves), and persons. Most laws were passed  by assemblies dominated by the patrician families, though the rulings of  magistrates were also important. Later emperors bypassed these forms and  issued their own decrees. The interpretations of jurists also came to have  the weight of law. Though various attempts were made to gather and sim�  plify existing laws (beginning with the Law of the Twelve Tables), by far</p><p>the most successful effort was that of Justinian I, whose code superseded  all previous laws and formed the Roman Empire�s legal legacy (see Code  of Justinian). Roman legal procedure is the basis for modern procedure in  civil - law countries. In the early Republic, the plaintiff was required to call  the defendant to court or to bring him by force. A magistrate then decided  whether the case should go before a judex, or prominent layman. The  judex heard arguments from advocates and questioned witnesses; he made  a decision but had no power to execute it. In the later Republic, much  greater power was placed in the hands of the magistrates and courts: the  summons was issued by the court, the trial was held only before a mag�  istrate, and the court became responsible for the execution of the sentence.</p><p>Roman mythology Oral and literary traditions of the ancient Romans  concerning their gods and heroes and the nature and history of the cos�  mos. Much of what became Roman mythology was borrowed from Greek  mythology at a later date, as Greek gods were associated with their Roman  counterparts. As in Greek mythology, legendary Roman heroes (such as  Romulus and Remus and Aeneas) were given semidivine status. See also  Roman religion.</p><p>Roman numerals System of representing numbers devised by the  ancient Romans. The numbers are formed by combinations of the sym�  bols I, V, X, L, C, D, and M, standing, respectively, for 1,5, 10, 50, 100,  500, and 1,000 in the Hindu-Arabic numeral system. A symbol placed after  another of equal or greater value adds its value; for example, II = 2 and  LX = 60. A symbol placed before one of greater value subtracts its value;  for example, IV = 4 and XL = 40. A bar over a symbol indicates that its  value should be multiplied by 1,000.</p><p>1</p><p>1</p><p>8</p><p>VIII</p><p>40</p><p>XL</p><p>900</p><p>CM</p><p>2</p><p>11</p><p>9</p><p>IX</p><p>50</p><p>L</p><p>1,000</p><p>M</p><p>3</p><p>III</p><p>10</p><p>X</p><p>60</p><p>LX</p><p>5,000</p><p>V</p><p>4</p><p>IV</p><p>11</p><p>XI</p><p>90</p><p>XC</p><p>10,000</p><p>X</p><p>5</p><p>V</p><p>19</p><p>XIX</p><p>100</p><p>C</p><p>50,000</p><p>L</p><p>6</p><p>VI</p><p>20</p><p>XX</p><p>200</p><p>CC</p><p>100,000</p><p>C</p><p>7</p><p>VII</p><p>30</p><p>XXX</p><p>500</p><p>D</p><p>500,000</p><p>D</p><p>Roman question Dispute between church and state in Italy. With the  completed unification of Italy in 1870, the papacy objected to the Italian  seizure of Rome and the Papal States. The conflict was ended in 1929 by  the Lateran Treaty, which created Vatican City and resolved the dispute.</p><p>Roman religion Religious beliefs of the Romans from ancient times  until official acceptance of Christianity in the 4th century ad. The Romans  believed that everything was subordinate to the rule of the gods, and the  object of their religion was to secure divine cooperation and benevolence.  Prayer and sacrifice were used to propitiate the gods and were often car�  ried out at temples dedicated to particular divinities and presided over by  priests (see flamen). The chief Roman priest, head of the state religion,  was known as the pontifex maximus\ notable among the other groups of  priests were the augurs, who practiced divination to determine whether the</p><p>Roman Gods and Goddesses</p><p>Apollo</p><p>god of sunlight, music,</p><p>Mars</p><p>god of war</p><p>poetry, and, prophecy</p><p>Mercury</p><p>messenger god and god</p><p>Aurora</p><p>goddess of the dawn</p><p>of commerce</p><p>Bacchus</p><p>god of wine</p><p>Minerva</p><p>goddess of wisdom, the</p><p>Bellona</p><p>goddess of war</p><p>arts, and trades</p><p>Ceres</p><p>goddess of agriculture</p><p>Mithra</p><p>god of light</p><p>Cupid</p><p>god of love</p><p>Neptune</p><p>god of the sea</p><p>Diana</p><p>goddess of fertility, hunt-</p><p>Ops</p><p>goddess of abundance</p><p>ing, and the moon</p><p>Pales</p><p>goddess of flocks and</p><p>Dis or Orcus</p><p>god of the underworld</p><p>shepherds</p><p>Faunus</p><p>god of pastures, forests,</p><p>Pomona</p><p>goddess of fruit trees and</p><p>and herds</p><p>fruit</p><p>Flora</p><p>goddess of flowers</p><p>Proserpine</p><p>goddess of the under-</p><p>Janus</p><p>god of gates and doors</p><p>world</p><p>Juno</p><p>goddess of marriage and</p><p>Saturn</p><p>god of seed time and</p><p>women</p><p>harvest</p><p>Jupiter</p><p>supreme god and god of</p><p>Venus</p><p>goddess of beauty and</p><p>the sky and weather</p><p>love</p><p>Libitina</p><p>goddess of funerals</p><p>Vertumnus</p><p>god of the seasons</p><p>Maia</p><p>goddess of growth and</p><p>Vesta</p><p>goddess of the hearth</p><p>increase</p><p>Vulcan</p><p>god of fire</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Roman Republic and Empire &#x25BA; Romania I 1637</p><p>gods approved of an action. The earliest Roman gods were the sky god  Jupiter, the war god Mars, and Quirinus; other important early gods were  Janus and Vesta. Many other deities were borrowed from Greek religion  or associated with Greek gods, and the stories woven into Roman mythol�  ogy were often taken directly from Greek mythology. Domestic shrines  were devoted to divine ancestors or protectors, the Lares and Penates. Dead  Roman emperors were also raised to the status of divinities and were  regarded with veneration and gratitude.</p><p>Roman Republic and Empire Ancient state that once ruled the  Western world. It centred on the city of Rome from the founding of the  republic (509 bc) through the establishment of the empire (27 bc) to the  final eclipse of the empire in the west (5th century ad). The republic�s  government consisted of two consuls, the Senate, and magistrates, origi�  nally all patricians, and two popular plebeian assemblies: the military cen-  turiate assembly and the civilian tribal assembly. A written code, the Law  of the Twelve Tables (451 bc), became the basis of Roman private law. By  the end of the 3rd century bc, Roman territory included all of Italy; by  the late republican period it encompassed most of western Europe, north�  ern Africa, and the Near East, organized into provinces. After a period of  civil war, Julius Caesar took power as dictator. Following his assassina�  tion (44 bc), conflict among the triumvirs�Mark Antony, Lepidus, and  Octavian�ultimately resulted in Octavian�s victory (31) and his acces�  sion as Emperor Augustus (r. 27 bc-ad 14). The imperial government, a  principate, combined aspects of the republic and a monarchy. In ad 395  the empire split into eastern and western halves, with the west under  severe pressure from the barbarians. Rome was sacked in 410 by the  Visigoths, and the western empire fell to German invaders in 476; the east  continued as the Byzantine Empire until 1453. See table opposite.</p><p>romance Literary form that developed in the aristocratic courts of mid-  12th-century France and had its heyday in France and Germany between  the mid-12th and mid-13th century in the works of such masters as Chre�  tien de Troyes and Gottfried von Strassburg. The staple subject matter is  chivalric adventure (see chivalry), though love stories and religious alle�  gories are sometimes interwoven. Most romances draw their plots from  classical history and legend, Arthurian legend, and the adventures of Char�  lemagne and his knights. Written in the vernacular, they share a taste for  the exotic, the remote, and the miraculous. Lingering echoes of the form  can be found in later centuries, as in the Romanticism of the 18th-19th  century and today�s popular romantic novels.</p><p>Romance languages Group of related languages derived from Latin,  with nearly 920 million native speakers. The major Romance languages�  French, Spanish, Portuguese, Italian, and Romanian �are national lan�  guages. French is probably the most internationally significant, but  Spanish, the official language of 19 American countries and Spain and  Equatorial Guinea, has the most speakers. Languages spoken in smaller  areas include Catalan, Occitan, Sardinian, and Rhaeto-Romance. The  Romance languages began as dialects of Vulgar Latin, which spread dur�  ing the Roman occupation of Italy, the Iberian Peninsula, Gaul, and the  Balkans and developed into separate languages in the 5th-9th centuries.  Later, European colonial and commercial contacts spread them to the  Americas, Africa, and Asia.</p><p>Romanesque architecture Architecture current in Europe from  about the mid-11th century to the advent of Gothic architecture. A fusion  of Roman, Carolingian and Ottonian, Byzantine, and local Germanic tra�  ditions, it was a product of the great expansion of monasticism in the 10th�  11th century. Larger churches were needed to accommodate the numerous  monks and priests, as well as the pilgrims who came to view saints� rel�  ics. For the sake of fire resistance, masonry vaulting began to replace tim�  ber construction. Romanesque churches characteristically incorporated  semicircular arches for windows, doors, and arcades; barrel or groin vaults  to support the roof of the nave; massive piers and walls, with few win�  dows, to contain the outward thrust of the vaults; side aisles with galler�  ies above them; a large tower over the crossing of nave and transept; and  smaller towers at the church�s western end. French churches commonly  expanded on the early Christian basilica plan, incorporating radiating chap�  els to accommodate more priests, ambulatories around the sanctuary apse  for visiting pilgrims, and large transepts between the sanctuary and nave.</p><p>Romanesque art Sculpture and painting that reached its height in  western Europe c. 1075-1125, a fusion of Roman, Carolingian and Otton�  ian, and Byzantine art with local Germanic traditions.

The name Romanian is  usually identified with Daco-Romanian, one of the four major dialects of  Balkan Romance. Other dialects are Aromanian (Macedo-Romanian),  spoken in scattered communities in Greece, Macedonia, Albania, and Bul�  garia; the nearly extinct Megleno-Romanian, spoken in northern Greece;  and Istro-Romanian, spoken on Croatia�s Istrian Peninsula. The earliest  known continuous text in Romanian dates from 1521. Romanian�s pho�  nology, grammar, and vocabulary reflect its relative isolation from other  Romance languages and its close contact with the Slavic languages.

The name derived from Roman Yurev (d. 1543), whose  daughter Anastasiya Romanovna was the first wife of Ivan IV the Terrible.  Her nephews assumed the surname Romanov, and the dynasty began with  the election of Michael Romanov as tsar in 1613. He was succeeded by  his son Alexis (r. 1645-76), followed by Alexis�s sons Fyodor III and joint  rulers Ivan V and Peter I. When Peter was sole ruler, he decreed in 1722  that the monarch could choose his successor, but he was unable to effect  the law, so the crown passed to his wife Catherine I, his grandson Peter II,  and Ivan V�s daughter Anna. The line of descent returned to Peter�s  daughter Elizabeth (r. 1741-62), her nephew Peter III and his wife Cathe�  rine II the Great, and their son Paul I. Paul established a definite order of  succession and was followed by his sons Alexander I (r. 1801-25) and  Nicholas I (r. 1825-55). Nicholas was succeeded by his son Alexander II,  grandson Alexander III, and great-grandson Nicholas II (r. 1894-1917), the  last ruler of the Russian monarchy.</p><p>Romanticism Literary, artistic, and philosophical movement that began  in Europe in the 18th century and lasted roughly until the mid- 19th century.  In its intense focus on the individual consciousness, it was both a continu�  ation of and a reaction against the Enlightenment. Romanticism emphasized  the individual, the subjective, the irrational, the imaginative, the personal,  the spontaneous, the emotional, the visionary, and the transcendental.  Among its attitudes were a deepened appreciation of the beauties of nature;  a general exaltation of emotion over reason and of the senses over intellect;  a turning in upon the self and a heightened examination of human person�  ality; a preoccupation with the genius, the hero, and the exceptional figure;  a new view of the artist as a supremely individual creator; an emphasis on  imagination as a gateway to transcendent experience and spiritual truth; a  consuming interest in folk culture, national and ethnic cultural origins, and  the medieval era; and a predilection for the exotic, the remote, the myste�  rious, the weird, the occult, the monstrous, the diseased, and even the  satanic.

Romberg studied engineering and composition in Vienna,  becoming a skilled violinist and organist. In 1909 he went to New York  City, where he conducted a restaurant orchestra and played piano in cafes.  As staff composer for the impresario Jacob Shubert (see Shubert Brothers),  Romberg prepared scores for about 40 musical shows. His first notable  operetta, May time (1917), was followed in the 1920s by Blossom Time  (1921), The Student Prince (1924), The Desert Song (1926), and The New  Moon (1928).

It is situated on the Tiber River in the central part of the country. The histori�  cal site of Rome on its seven hills was occupied as early as the Bronze Age  (c. 1500 bc), and the city was politically unified by the early 6th century bc.  It became the capital of the Roman Empire (see Roman Republic and Empire).  The Romans gradually conquered the Italian peninsula (see Etruscan),  extended their dominion over the entire Mediterranean basin (see Punic  Wars), and expanded their empire into continental Europe. Under Pompey  the Great and Julius Caesar, Rome�s influence was extended over Syria,  Jerusalem, Cyprus, and Gaul. After the Battle of Actium, all Roman lands  were controlled by Octavian (Augustus), the first Roman emperor. As the  imperial capital, Rome became the site of magnificent public buildings,  including palaces, temples, public baths, theatres, and stadiums.

It remained the capital of the Roman Empire until  Emperor Constantine the Great dedicated Constantinople (now Istanbul) in  330. By the end of the 6th century the protection of the city was in the hands  of the Roman Catholic church (see Holy Roman Empire), which achieved  absolute rule only in the 15th century. The city flourished during the Renais�  sance and was the seat of the papacy and the Papal States. In 1870 it became  the capital of a united Italy. It was transformed into a modem capital in the  1920s and �30s and is Italy�s administrative, cultural, and transportation  centre.

Social discontent gave Fascist Party leaders the  opportunity to take control of the Italian government. Assisted by the  armed squads known as Blackshirts, they planned to march on Rome and  force King Victor Emmanuel III to call on Mussolini to form a government.  Since the king was unwilling to use the Italian army to defend Rome, the  government capitulated to the Fascists� demands. The March on Rome  turned into a parade to show the Fascist Party�s support for Mussolini as  the new prime minister.</p><p>Rome, Treaties of Two international agreements signed in Rome in  1957 by Belgium, France, West Germany, Italy, Luxembourg, and the  Netherlands.

A  teacher at military academies, he  wrote the acclaimed textbook Infan�  try Attacks (1937). He commanded a  panzer division in the invasion of  France (1940), then led his Afrika  Korps troops in early successes  against the Allies in the North Africa  Campaign. He became known as the  �Desert Fox� for his audacious sur�  prise attacks, and he was promoted  to field marshal. In 1942 he was  ordered to attack Cairo and the Suez  Canal, despite his request to with�  draw his exhausted troops. After his  defeat in the Battles of El Alamein and  retreat into Tunisia, he returned to  Germany and in 1944 was given  command of the defense of the northwestern French coast. His tactical  suggestions were ignored, and after the Allied Normandy Campaign began,  he became convinced that the war could not be won. Implicated in the  July Plot to kill Adolf Hitler, he was ordered to take poison so that Hitler  could avoid a trial of the esteemed �people�s marshal.�</p><p>Romney, George (b.

Son of a Lancashire cabinet�  maker, he began his career by tour�  ing the northern counties, painting  portraits for a few guineas each. In  1762 he established himself as a por�  traitist in London and quickly won  favour among society patrons. His  success depended on the flattery of  his likenesses; he avoided any sug�  gestion of the sitter�s character or  sensibilities. Infatuated with Emma  Hart (later Lady Hamilton) c. 1781�</p><p>82, he went on to paint more than 50  images of her.

Suckled by a she-wolf and raised by a shepherd, the  twins later deposed Amulius, restored their grandfather Numitor to the  throne, and founded a city on the site where they had been saved from  the river. When Romulus built a city wall, Remus jumped over it and was  killed by his brother. The city was named for Romulus, who ruled until  his disappearance in a storm.

The rondeau has only two rhymes  (allowing no repetition of rhyme words) and consists of 13 or 15 lines of  8 or 10 syllables divided into three stanzas. The beginning of the first line  of the first stanza serves as the refrain of the second and third stanzas.</p><p>rondo Musical form characterized by the initial statement and periodic  restatement of a melody alternately with contrasting material. It originated  in the French Baroque harpsichord rondeau, where a refrain of 8 or 16  measures is played in alternation with a succession of couplets (episodes)  so as to form a chainlike structure of variable length. Most rondos fall  into either a five-part (abaca) or a seven-part ( abacaba ) form. The rondo  was very popular in the late 18th and the early 19th centuries, frequently  providing the form for the final movements of sonatas, quartets, sympho�  nies, and concertos.</p><p>Rondon \ron-'don\, Candido (Mariano da Silva) (b.

Ronin could be disruptive to society; at the beginning of the  Tokugawa period (the early 17th century), ronin led unsuccessful revolts  against the shogunate. The most famous ronin were the 47 whose actions  were celebrated in the kabuki play Chiishingura. By avenging their lord�s  death in defiance of a shogunal order forbidding the vendetta, the 47 ronin,  who were subsequently forced to commit seppuku (ritual suicide), came to  be seen as embodiments of the ideals of bushido, the warrior�s code.</p><p>Ronsard \ron-'sar\, Pierre de (b.

Of a noble family, Ronsard turned to scholarship and literature after  an illness left him partially deaf. He was the foremost poet of La Pleiade,  a literary group that used Classical and Italian models to elevate the  French language as a medium for literary expression. He was recognized  in his lifetime as a prince of poets; among his diverse works were Odes  (1550), inspired by Horace; Les Amours (1552); the unfinished La Fran-  ciade (1572), in imitation of Virgil�s Aeneid, meant to be the national epic;  and Sonnets pour Helene, now perhaps his most famous collection. He  perfected and established the alexandrine as the classic form in French for  scathing satire, elegiac tenderness, and tragic passion.</p><p>Rontgen Yrent-gan, 'ront-jonV, Wilhelm Conrad or Wilhelm  Conrad Roentgen (b.

In 1895 he discovered rays that  did not exhibit properties such as  reflection or refraction and mistak�  enly thought they were unrelated to  light. Because of their mysterious  nature, he called them X-rays. He  later produced the first X-ray photo�  graphs, showing the interiors of  metal objects and the bones in his  wife�s hand. He also did important  research in a wide variety of other  fields. In 1901 he was awarded the  first Nobel Prize for Physics.</p><p>roof Covering of the top of a build�  ing. Roofs have been constructed in  a wide variety of forms�flat,</p><p>pitched, vaulted, domed, or in combinations�as dictated by regional,  technical, and aesthetic considerations. Thatched roofs, usually sloping,  were the earliest type and are still used in rural Africa and elsewhere. Flat  roofs have historically been used in arid climates where drainage of water  off the roof is not important, as in the Middle East and the southwestern  U.S. They came into more widespread use in the 19th century, when new  waterproof roofing materials and the use of structural steel and concrete  made them more practical. Sloping roofs come in many different variet�  ies. The simplest is the lean-to (or shed) roof, which has only one slope.  A roof with two slopes that form a triangle at each end is called a gable  roof. A hipped (or hip) roof has sloping sides and ends meeting at inclined  projecting angles called hips. The gambrel roof has two slopes on each  of its two sides, the upper being less steep than the lower. The mansard  roof has two slopes on all four sides, a shallower upper part and a steeper  lower part. See also hammer-beam roof.</p><p>roof pendant Downward extension of the surrounding rock that pro�  trudes into the upper surface of intrusive rocks. Most intrusions that con�  tain roof pendants are relatively shallow; the roof pendants occur as  isolated pieces of the surrounding rock within the intrusive mass. Because  roof pendants are exposed by erosion of the overlying rock, their pres�  ence indicates that the igneous body is being observed near its upper sur�  face. Roof pendants can be studied to determine some of the conditions  that existed at the time of intrusion, such as the temperature and compo�  sition of the MAGMA.</p><p>rook Most abundant Eurasian bird (Corvus frugilegus) of the crow fam�  ily (Corvidae).

He starred in 50 RKO short comedies  as Mickey McGuire (1927-33) and won praise for his roles in A Mid�  summer Night�s Dream (1935) and Boys Town (1938). From 1937 he  played the cocky, energetic Andy Hardy in a series of popular films, often  teamed with Judy Garland. His later film successes include The Human  Comedy (1943), National Velvet (1944), Baby Face Nelson (1957), and  The Black Stallion (1979).

As first lady (1933-45), she  traveled around the U.S. to report on  living conditions and public opinion  for her husband, and she supported  humanitarian causes such as child  welfare, equal rights, and social  reforms. During World War II, she  traveled in Britain and the South  Pacific as well as to U.S. military  bases to help raise morale. She wrote  the syndicated column �My Day,� as  well as several books. After her husband�s death, she was appointed a  delegate to the UN (1945, 1949-52, 1961), whose founding she had  strongly advocated. As chair of its Commission on Human Rights (1946-  51), she helped draft the Universal Declaration of Human Rights (1948).

In 1905 he married  Eleanor Roosevelt, who would become a valued adviser in future years.  He served in the New York senate (1910-13) and as U.S. assistant sec�  retary of the navy (1913-20). In 1920 he was nominated by the Demo�  crats as their vice presidential candidate. The next year he was stricken  with polio; though unable to walk, he remained active in politics. As gov�  ernor of New York (1929-33), he set up the first state relief agency in the  U.S. In 1932 he won the Democratic presidential nomination with the help  of James Farley and easily defeated Pres.

In 1940 he was reelected to an unprecedented third term, defeat�  ing Wendell Willkie. He developed the lend-lease program to aid U.S. allies,  especially Britain, in the early years of World War II. In 1941 he met with  Winston Churchill to draft the Atlantic Charter. With U.S. entry into war,  Roosevelt mobilized industry for military production and formed an alli�  ance with Britain and the Soviet Union; he met with Churchill and Joseph  Stalin to form war policy at Tehran (1943) and Yalta (1945). Despite  declining health, he won reelection for a fourth term against Thomas Dewey  (1944) but served only briefly before his death.</p><p>Roosevelt, Theodore known as Teddy Roosevelt (b.

He was elected to the New York legis�  lature (1882), where he became a Republican leader opposed to the Demo�  cratic political machine. After political defeats and the death of his wife,  he went to the Dakota Territory to ranch. He returned to New York to  serve on the U.S. Civil Service Commission (1889-95) and as head of the  city�s board of police commissioners (1895-97). A supporter of William  McKinley, he served as assistant secretary of the navy (1897-98). When  the Spanish-American War was declared, he resigned to organize a cavalry  unit, the Rough Riders. He returned to New York a hero and was elected  governor in 1899. As the Republican vice-presidential nominee, he took  office when McKinley was reelected, and he became president on Mc�  Kinley�s assassination in 1901. One of his early initiatives was to urge  enforcement of the Sherman Antitrust Act against business monopolies.  He won election in his own right in 1904, defeating Alton Parker. At his  urging, Congress regulated railroad rates and passed the Pure Food and  Drug Act and Meat Inspection Act (1906) to protect public health. He  created national forests and set aside mineral, oil, and coal deposits for  conservation. He and secretary of state Euhu Root announced the  Roosevelt corollary to the Monroe Doctrine, which reasserted the U.S.�s  position as protector of the Western Hemisphere. For mediating an end  to the Russo-Japanese War, he received the 1906 Nobel Prize for Peace.  He secured a treaty with Panama for construction of a trans-isthmus canal.  Declining to seek reelection, he secured the nomination for William H.  Taft. After traveling in Africa and Europe, he tried to win the Republican  presidential nomination in 1912; when he was rejected, he organized the  Bull Moose Party and ran on a policy of New Nationalism. Though he lost  the election, he secured 88 electoral votes�the most successful third-  party candidacy in the 20th century. Throughout his life he continued to  write, publishing extensively on history, politics, travel, and nature.

Primary root systems have a deep sturdy taproot  (in gymnosperms and dicots; see cotyledon) plus secondary or lateral  smaller roots, and root hairs. Grasses and other monocots produce a shal�  low diffuse mass of fibrous secondary roots. Additional support (e.g., in  corn and orchids) comes from stem offshoots called adventitious, or prop,  roots. Fleshy roots that store food may be modified taproots (e.g., carrots,  turnips, and beets) or modified adventitious roots (e.g. cassava). Tubers such  as the potato are modified, fleshy, underground stems, or rhizomes. Aerial  roots arise from the stem and either pass for some distance through the  air before reaching the soil or remain hanging in the air. See illustration  opposite.</p><p>Root, Elihu (b.

Cells of the cortex store food and  transport water and substances to the endodermis, which regulates their entry into  the vascular cylinder, containing the xylem (for transporting water and dissolved  minerals to the rest of the plant) and phloem (for transporting nutrients made in the  leaves).</p><p>� MERRIAM-WEBSTER INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1642 I Rorty &#x25BA; rose window</p><p>Rorty, Richard (McKay) (b. Oct. 4,1931, New York, N.Y., U.S.) U.S.  philosopher. After receiving his Ph.D. at Yale University in 1956, he  taught at Wellesley College, Princeton University, the University of Vir�  ginia, and Stanford University. An opponent of epistemological founda-  tionalism, Rorty holds that no statement is epistemologically more basic  than any other and no statement is ever justified finally or absolutely. He  also rejects the idea that sentences or beliefs are true or false in any inter�  esting sense other than being useful or successful within a broad social  practice (see pragmatism). Because there is no such thing as certainty or  absolute truth, according to Rorty, it is not the purpose of philosophy to  pursue such things; its role instead should be to conduct a �conversation�  between contrasting but equally valid forms of intellectual inquiry. His  publications include Philosophy and the Mirror of Nature (1979), Con�  sequences of Pragmatism (1982), and Contingency, Irony and Solidarity</p><p>(1989).</p><p>Rosa, Salvator (b.

He left office  in 1833 to pursue a war against the Indians, and in 1835 he again became  governor of Buenos Aires, this time with dictatorial powers. He was the  quintessential caudillo, a tyrant who cultivated a fiercely loyal personal  following and ruled by intimidation and patronage.

Rose quartz is valued for its pale to rich pink  colour, which is due to very small amounts of titanium. It has been carved  since early times and has been faceted to provide gems of good brilliance.  Its milky aspect is attributed to tiny, needlelike inclusions of rutile, which,  when oriented, give the polished stone an asterism (optical phenomenon  of a star-shaped figure) like that found in sapphire, but not as sharp or  intense.

He succeeded Gladstone as prime  minister (1894-95) but was ineffective in resolving conflicts within the  Liberal Party and in passing legislation through the Conservative-  dominated House of Lords.

In the American Civil War he led Union  forces to victory at Iuka and Corinth, Miss., and at Murfreesboro, Tenn.  In 1863 he advanced on Confederate troops under Braxton Bragg at Chat�  tanooga, Tenn., forcing them out of the city. An ill-planned move pre�  cipitated the Battle of Chickamauga and forced his troops to retreat into  Chattanooga, where they were besieged; Rosecrans�s error led to his  removal from command.

German Nazi ideologue. As editor of the Nazi Party  newspaper from 1921, he drew on the ideas of the English racist Hous�  ton Stewart Chamberlain for his books espousing German racial purity and  anti-Semitism, which reinforced Adolf Hitler�s own extreme prejudices.  In World War II he oversaw the transport of stolen art into Germany and  was a government official in the occupied eastern territories.

They were married in 1939, by which time  they were already active in the Communist Party. In 1940 Julius became  an engineer with the U.S. Army Signal Corps. He and his wife, Ethel,  apparently gave military secrets to the Soviet military in a conspiracy with  Ethel�s brother, Sgt. David Greenglass, a machinist on the atomic-bomb  project at Los Alamos, N.M., and Harry Gold, a courier for the U.S.  espionage ring. They were all arrested in mid-1950. Greenglass and Gold  received prison terms, but the Rosenbergs were sentenced to death.  Despite several appeals and a worldwide campaign for mercy, they were  executed at Sing Sing Prison in 1953, the only U.S. civilians ever executed  for espionage. Despite considerable controversy in subsequent years, the  question of their guilt was largely resolved in the early 1990s, when the  release of Soviet intelligence information confirmed the Rosenbergs�  involvement in espionage.</p><p>Rosenquist, James (b.

His youthful employment as a billboard painter influenced the  enlarged imagery and cool, impersonal style of painting that he devel�  oped by the early 1960s. In a typical painting, he juxtaposed imagery from  pop culture, advertising, and other mass media using bright colours and  a large canvas. This interest in popular culture has led many to define him</p><p>as a precursor to Pop art. He has also created large works combining  lithography, screenprinting, etching, and collage.</p><p>Rosenzweig Yro-zan-.tsvIkV Franz (b. Dec. 25, 1886, Kassel,  Ger.�d.

He briefly thought of con�  verting to Christianity from Judaism but turned instead to an intensive  reading of the Hebrew classics. While serving in World War I, he began  to formulate the existentialist understanding of faith and belief that would  eventuate in his major work, The Star of Redemption (1921). He collabo�  rated with Martin Buber on a translation of the Hebrew scriptures in which  he tried to restore what he thought was the existentialist tone of the origi�  nal.</p><p>Roses, Wars of the (1455 -85) Series of dynastic civil wars between  the houses of Lancaster and York for the English throne. The wars were  named for the emblems of the two houses, the white rose of York and the  red of Lancaster. Both claimed the throne through descent from Edward  III. Lancastrians held the throne from 1399, but the country fell into a state  of near anarchy during the reign of Henry VI, and during one of Henry�s  bouts with madness in 1453 the duke of York was declared protector of  the realm. Henry reestablished his authority in 1455, and the battle was  joined. The Yorkists succeeded in putting Edward IV on the throne in 1461,  but the wars continued, and in 1471 they murdered Henry VI in the Tower  of London. In 1483 Richard III overrode the claims of his nephew Edward  V to seize the throne, alienating many Yorkists. The Lancastrian Henry  Tudor (Henry VII) defeated and killed Richard at the Battle of Bosworth  Field, ending the wars. He united the houses by marriage and defeated a  Yorkist rising in 1487.

Sometimes  called the Day of Judgment, Rosh Hashanah falls on Tishri 1 (in Sep�  tember or October) and ushers in a 10-day period of self-examination and  penitence that ends with Yom Kippur. The liturgy includes the blowing of  the ram�s horn, or shofar, a call for spiritual awakening associated with  the giving of the Law to Moses on Mount Sinai. It is also called the Day  of Remembrance, since it celebrates the creation of the world and the  responsibilities of the Jews as God�s chosen people.

According  to legend, in 1776 she was visited by George Washington, Robert Morris,  and her husband�s uncle George Ross, who asked her to make a flag for  the new nation based on a sketch by Washington. She is supposed also to  have suggested the use of the five-pointed star rather than the six-pointed  one chosen by Washington.

He later became presi�  dent of the National Council of Cherokees (1819-26). As principal chief  of the Cherokee Nation (1828-39), he resisted government attempts to  seize Cherokee farms and lands in Georgia and unsuccessfully petitioned  Jackson to defend the Indians� rights.

His tomb for Leonardo Bruni  (1444-50) in Santa Croce, Florence, was one of the greatest achievements  of early Renaissance sculpture and inaugurated a new type of sepulchral  monument. Its fine balance between sculpture and architecture, figure and  decoration, made it the prototypical niche tomb of its time. He also  designed the apse of St. Peter's Basilica and the cathedral and Piccolomini  Palace in Pienza (1460-64).

As an informal pupil of Ford Madox Brown, he absorbed  Brown�s admiration for the German Nazarenes. In 1848, with several  friends, he formed the Pre-Raphaelite Brotherhood, a group of painters  treating religious, moral, and medieval subjects in a naturalistic style.

Feb. 28, 1783,</p><p>Vasto, Kingdom of Naples�d. April  24, 1854, London, Eng.) Italian poet,  revolutionary, and scholar. A libret�  tist and later curator of a museum in  Naples, he was condemned for his  spirited verse on contemporary poli�  tics and for membership in a revolutionary group. In 1824 he fled to  England, where in 1831 he published an eccentric interpretation of Dante,  claiming a chiefly political and antipapal meaning in the Divine Comedy.  The work led to a post as professor of Italian at King�s College, London,  from 1831 to 1847. He is best known as the father of four talented chil�  dren, including Christina Rossetti and Dante Gabriel Rossetti.</p><p>Rossini, Gioacchino (Antonio) (b. Feb. 29, 1792, Pesaro, Papal  States�d. Nov. 13, 1868, Passy, France) Italian composer. He sang in  church and in minor opera roles as a child, began composing at age 12,  and at 14 entered Bologna�s conservatory, where he wrote mostly sacred  music. From 1812 he produced theatre works at a terrific rate, and for 15  years he was the dominant voice of Italian opera; his major successes  included The Italian Girl in Algiers (1813), The Barber of Seville (1816),  La cenerentola (1817), and Semiramide (1823). Into the genteel atmo�  sphere of lingering 18th-century operatic manners, Rossini brought genu�  ine originality marked by rude wit and humour and a willingness to  sacrifice all �rules� of musical and operatic decorum. His career marked  the zenith of the bel canto style, a singer-dominated manner of compo�  sition that emphasized vocal agility and long, florid phrasing. From 1824  he spent much time in Paris, where he wrote his masterpiece, William Tell  (1829). After 1832 his health was poor, and he composed little until the  series of piano pieces and songs collected as Sins of My Old Age (1868).</p><p>Rosso \'ros-so\, Giovanni Battista (di Jacopo) known as Rosso  Fiorentino or II Rosso (b. March 8, 1495, Florence, Republic of  Florence�d. Nov. 14, 1540, Paris, Fr.) Italian painter and decorator. He  trained under Andrea del Sarto, alongside Jacopo da Pontormo, with whom  he became a leading figure in the development of Mannerism. In his later  work, the highly charged emotionalism of his early works (e.g., the  Assumption fresco, 1513-14, in Florence�s Santissima Annunziata) is  more subdued; his new style is seen in his Dead Christ with Angels  (1525-26). In 1530 he went to France at the invitation of Francis I; there  he became a founder of the Fontainebleau school, and the ornamental style  he developed influenced decorative arts across northern Europe. He  remained in the royal service until his death.</p><p>Rostand \ros-'ta n \, Edmond (-Eugene) (b. April 1, 1868, Marseille,  France�d. Dec. 2, 1918, Paris) French playwright. He wrote poetry,  essays, and plays for puppet theatre before his first stage play. The Red  Glove , was performed in 1888. His most popular work is the heroic com�  edy Cyrano de Bergerac (1898), the story of an ugly, long-nosed soldier  who despairs of winning the woman he loves and helps a friend woo her  instead. A final, belated example of French Romantic drama, it was enor�  mously successful internationally. He also wrote The Eaglet (1900) for  Sarah Bernhardt.</p><p>Rostock Vr6-,st6k\ City (pop., 2002 est.: 198,964) and seaport, north�  eastern Germany. Located on the Wamow River, 8 mi (13 km) from the  Baltic Sea, Rostock was founded in 1218 and was a powerful member of  the Hanseatic League in the 14th century. Sailing ships were built in its  shipyards from the medieval period until 1851, when the first German</p><p>steam-propelled vessel was built there. The city was heavily damaged by  Allied bombing in World War II. After the war the town centre was rebuilt,  and it was developed as East Germany�s principal ocean port.

It was fortified soon after, and, because of its key position  as a transport centre and port, it grew steadily with 19th-century Russian  colonization. Occupied by the Germans in World War II, it suffered exten�  sive damage but was rebuilt after the war. It is a transportation and indus�  trial centre. The city�s nodal location and the proximity of the Donets Basin  have led to major industrial development, especially in engineering.</p><p>Rostropovich \,r6s-tr3-'po-vich\, Mstislav (Leopoldovich) (b.</p><p>March 27, 1927, Baku, Azerbaijan S.S.R., U.S.S.R.)

He had works  written for him by such composers as Shostakovich, Sergey Prokofiev, and  Benjamin Britten. A political dissident, he left the Soviet Union in 1974  and made his career in the West. Settling in the U.S., he served as music  director of the National Symphony Orchestra (1977-94) while continu�  ing to make many solo appearances, becoming perhaps the world�s most  famous cellist.

From 1950 to 1978 he served as director of the Liceo  Musicale, a conservatory in Bari. In 1950 he also began his long asso�  ciation with Federico Fellini, for whom he would score films such as La  strada (1955), La dolce vita (1960), 8 V 2 (1963), and Amarcord (1973).

March 19, 1933, Newark, N.J.,U.S.) U.S.  writer. Roth attended the University of Chicago and first achieved fame  with Goodbye Columbus (1959), whose title story concerns the boorish  materialism of a suburban family. His works are characterized by an acute  ear for dialogue, a concern with Jewish middle-class life, and the painful  entanglements of sexual and familial love. Among his subsequent novels  are the comic and scandalous Portnoy�s Complaint (1969) and an admired  series centring on a writer named Nathan Zuckerman, including The Ghost  Writer (1979) and Zuckerman Unbound (1981).

Marcus Rothkowitz (b. Sept. 25, 1903,  Dvinsk, Russia�d. Feb. 25, 1970, New York, N.Y., U.S.) Russian-born  U.S. painter. His family settled in Portland, Ore., in 1913, and he took up  painting (largely self-taught) after moving to New York City in 1925. His  early realistic style culminated in the Subway series (late 1930s). The semi�  abstract forms of his work in the early 1940s developed into a highly per�  sonal, contemplative form of Abstract Expressionism by 1948. Unlike many  of his fellow Abstract Expressionists. Rothko never relied on such dramatic  techniques as violent brush strokes or the dripping and splattering of paint.  Instead, his virtually gestureless paintings achieved their effects by juxta�  posing large areas of melting colours that seemingly float parallel to the  picture plane in an indeterminate, atmospheric space. Rothko spent the rest  of his life refining this basic style through continuous simplification. In  1965-66 he completed 14 immense canvases, whose sombre intensity  reveals his deepening mysticism; they are now housed in a chapel in Hous�  ton, which was named the Rothko Chapel after his suicide.</p><p>Rothschild family European banking dynasty. It was founded by  Mayer Amschel Rothschild (1744-1812), who started out in a Frankfurt  banking house. The family name derived from the red shield (rote Schild)  on the house in the Jewish ghetto where Mayer�s ancestors lived. The  financial transactions of the Napoleonic Wars of 1792-1815 were the  foundation of the Rothschild fortune. Mayer and his oldest son, Amschel  (1773-1855), supervised the growing business from Frankfurt, while his  other sons established offices elsewhere: Nathan (1777-1836) established  a branch in London in 1804, James (or Jakob, 1792-1868) settled in Paris  in 1811, and Salomon (1774-1855) and Karl (1788-1855) opened offices  in Vienna and Naples, respectively, in the 1820s. The Rothschild business  later focused on government securities and industrial companies, includ�  ing railway, coal, ironworking, oil, and metallurgical investments. Their  powerful position was eventually threatened by the new commercial  banks, and by the late 19th century the Rothschild group was no longer  the first banking consortium. The Rothschilds received many honours:  Mayer�s five sons were made barons of the Austrian Empire, a Rothschild  was the first Jew to enter the British Parliament, and another was the first  to be elevated to the British peerage. Members of the British and French  families�the only ones still engaged in banking after the seizure of the  Austrian house by the Nazis�distinguished themselves as scientists and  philanthropists. Baron Philippe de Rothschild (1902-88) became a pre�  mier winemaker of the vineyard Mouton-Rothschild.</p><p>rotifer Vro-to-forV Any of about 2,000 species of microscopic, multicel�  lular, water-dwelling invertebrates  constituting the class Rotifera, or  Rotaria (phylum Aschelminthes; see  worm).

May 27, 1871, Paris, Fr.�d.  Feb. 13, 1958, Paris) French painter. His apprenticeship in a glazier�s shop  restoring medieval stained glass (1885�90) influenced his mature style as  a painter. After an early academic period, his style evolved toward Fau-  vism before he established a highly personal form of Expressionism. An  ardent Roman Catholic, he painted subjects apparently fallen from  grace�prostitutes, tragic clowns, and pitiless judges. After 1914 his sub�  ject matter became more specifically religious, with greater emphasis on  redemption, and he shifted from watercolour to oil. His layers of paint  became thick and rich, his forms simplified, and his colours and black  lines reminiscent of stained glass. In the 1930s he produced a splendid  series on Christ�s Passion, while reworking many earlier paintings. His  series of clowns in the 1940s are virtual self-portraits. He also produced  many engravings as well as ceramics, tapestry designs, and stained glass.</p><p>Rouen \ru-'a n \ City (pop., 1999: city, 106,592; metro, area, 389,862),  northwestern France.

Sacked by the Normans in 876, it became the medieval capital of Nor�  mandy. It came under English rule in 1066 and again in 1419. Joan of Arc  was imprisoned and executed there in 1431. Rouen was recaptured by the  French in 1449. Historic buildings include the 14th-century abbey of Saint  Ouen and the great Gothic cathedral, whose oldest parts date to the 11 th  century.

July 2, 1778, Ermenonville, France) Swiss-French philosopher. At age 16  he fled Geneva to Savoy, where he became the steward and later the lover  of the baronne de Warens. At age 30, having furthered his education and  social position under her influence, he moved to Paris, where he joined  Denis Diderot at the centre of the philosophes; he wrote on music and eco�  nomics for Diderot�s Encyclopedie. His first major work, the Discourse on  the Arts and Sciences (1750), argued that man is good by nature but has  been corrupted by society and civilization; Rousseau�s belief in the natu�  ral goodness of man set him apart from Roman Catholic writers who, like  him, were hostile to the idea of progress. He also wrote music; his light  opera The Cunning-Man (1752) was widely admired. In 1752 he became  involved in an influential dispute with Jean-Philippe Rameau over the rela�  tive merits of French and Italian music; Rousseau championed the latter.  In the Discourse on the Origin and Foundations of Inequality Among Men  (1754), he argued against Thomas Hobbes that human life before the for�  mation of societies was healthy, happy, and free and that vice arose as the  result of social organization and especially the introduction of private  property. Civil society, he held, comes into being only to ensure peace  and to protect property, which not everyone has; it thus represents a  fraudulent social contract that reinforces inequality. In the Social Con�  tract (1762), which begins with the memorable line, �Man was bom free,  but he is everywhere in chains,� Rousseau argues that a civil society based  on a genuine social contract rather than a fraudulent one would provide  people with a better kind of freedom in exchange for their natural inde�  pendence, namely, political liberty, which he understands as obedience to  a self-imposed law created by the �general will.� In 1762 the publication  of Emile , a treatise on education, produced outrage, and Rousseau was  forced to flee to Switzerland. He began showing signs of mental instabil�  ity c. 1767, and he died insane. His Confessions (1781-88), which he  modeled on the work of the same title by St. Augustine, is among the most  famous autobiographies.</p><p>Rousseau \rii-'so\, (Pierre-Etienne-) Theodore (b.

Because he strayed from the academic  path, his work was consistently rejected by the Salon. From the 1830s he  painted regularly in the village of Barbizon, where he became a leader of  the Barbizon school of landscape painters. His paintings, which show  nature as a wild, undisciplined force, counter the calmly idealized land�  scapes of Neoclassicism, and his small, highly textured brushstrokes  presage those of the Impressionists.</p><p>Roussel \rii-'sel\, Albert (-Charles-Paul-Marie) (b.

His opera-ballet Pad-  mavati (1918), with its Indian scales, won enthusiasm from younger com�  posers; his other important works include the ballets The Spider�s Feast  (1913) and Bacchus etAriane (1930) and the Third Symphony (1930).

He is also  remembered as the first to attempt a critical edition of William Shakespeare  (The Works of Mr. William Shakespear, 1709, 1714). His own poetry  includes odes and translations. He became poet laureate in 1715. Rowe  is regarded as the foremost 18th-century English tragic dramatist.</p><p>rowing Propulsion of a boat by means of oars.

During the 1930s and �40s the  popularity of his paintings represented the passage of modern Indian art  from its earlier academic leanings to new nativist predilections. Roy�s  subject matter ranged from the Ramayana to Christ to portraits of con�  temporary figures such as Mahatma Gandhi. He is one of the best-known  Indian artists of the 20th century.</p><p>Roy, Ram Mohun (b. May 22, 1772, Radhanagar, Bengal, India�d.  Sept. 27, 1833, Bristol, Gloucestershire, Eng.) Indian religious, social, and  political reformer. Born to a prosperous Brahman family, he traveled  widely in his youth, exposing himself to various cultures and developing  unorthodox views of Hinduism. In 1803 he composed a tract denouncing  India�s religious divisions and superstitions and advocating a monotheis�  tic Hinduism that would worship one supreme God. He provided modern  translations of the Vedas and Upanishads to provide a philosophical basis  for his beliefs, advocated freedom of speech and of religion, and  denounced the caste system and suttee. In 1826 he founded the Vedanta  College, and in 1828 he formed the Brahmo Samaj.</p><p>Royal Academy of Arts Britain�s national academy of art. It was  founded in 1768 by George III. Its first president (1768-92) was Joshua  Reynolds. The number of its members, who are selected by members and  associates, is fixed at 40; members� names are frequently followed by the  initials R.A. (�Royal Academician�). Its galleries contain works by such  former members as Thomas Gainsborough and J.M.W. Turner. The acad�  emy opened a new wing, the Sackler Galleries, in 1991.</p><p>Royal Air Force (RAF) Armed service charged with the air defense  of Britain and other international defense obligations. It originated in  1911, when an air battalion of the Royal Engineers was formed with one  balloon and one airplane company. The air battalion was assumed into the  Royal Flying Corps (RFC) in 1912, and in 1918 the RFC and Royal Naval  Air Services were merged into the RAF. (The Fleet Air Arm was returned  to the Royal Navy in 1937.) The Royal Air Force College was established  at Cranwell, Lincolnshire, in 1920 and the RAF Staff College at Andover,  Hampshire, in 1922. During World War II, pilots of the RAF Fighter  Command distinguished themselves in the Battle of Britain, and Bomber  Command conducted massive bombing raids on the German homeland.  All front-line units are now combined under the RAF Strike Command;  Personnel and Training Command handles recruiting, training, pensions,  and other personnel issues. Uniformed RAF personnel numbered some  48,000 at the start of the 21st century.</p><p>Royal Ballet English ballet company and school. In 1931 Ninette de  Valois and Lilian Bayus organized the Vic-Wells Ballet, naming it for the  two theatres (Old Vic and Sadler�s Wells) where it performed. In the 1940s  the group was called the Sadler�s Wells Ballet, after its theatre; it moved  to Covent Garden in 1946. Alicia Markova, Margot Fonteyn, and Robert  _ Helpmann were among the company�s early members. By the 1950s the</p><p>Sadler�s Wells Ballet had expanded to include its own school and a sepa-  wm rate touring company; in 1956 it received a royal charter and was renamed</p><p>ifl the Royal Ballet.

It is also the criminal and provincial force in all prov�  inces except Ontario and Quebec and the only force in the Yukon, North�  west, and Nunavut territories. It was founded as the North West Mounted  Police (1873) with a force of 300 men to bring order to western Canada,  where U.S. traders were creating havoc by trading whiskey to the Indi�  ans for furs. That success was followed by peacekeeping in the Klondike  gold rush (1898) and later settlement of the west. The group assumed its  current name in 1920, when it became a federal force and its headquar�  ters were moved to Ottawa.</p><p>Royal Dutch Shell PLC formerly Royal Dutch/Shell Group</p><p>Multinational corporation comprising two founding companies, Royal  Dutch Petroleum Co. of The Hague, Neth., and Shell Transport and Trad�  ing Co., PLC, of London, Eng. The two companies began as rivals. In  London in 1878, Marcus Samuel took over his father�s import-export  business (which included Oriental shells) and started selling kerosene; he  later entered the oil business in East Asia, and in 1897 he founded Shell  Transport and Trading Co., Ltd. Meanwhile, in 1890 a group of Dutch</p><p>businessmen founded the Royal Dutch Co. for the Exploitation of Oil  Wells in the Dutch Indies, which built its first refinery in Sumatra in 1892.  In 1907 the two companies merged into the Royal Dutch/Shell Group,  which acquired producing concerns in Egypt, Iraq, Romania, Russia,  Mexico, Venezuela, California, and Oklahoma. The group, commonly  referred to as Shell, has used the scallop shell as its logo since the early  1900s. With interests in liquefied natural gas and petrochemicals as well  as aviation, shipping, and automotive fuels. Royal Dutch Shell ranks  among the largest oil companies in the world.</p><p>Royal Greenwich \'gre-nich\ Observatory Astronomical observa�  tory, oldest scientific institution in Britain, founded for navigational pur�  poses in 1675 by Charles II at Greenwich, England. Its main contributions  have been in navigation, timekeeping, determination of star positions, and  almanac publication. In 1767 it began publishing The Nautical Almanac,  based on the time at the longitude of Greenwich; its popularity among  navigators led in part to the Greenwich meridian�s being made Earth�s  prime meridian and the starting point for international time zones in 1884  (see Greenwich Mean Time).</p><p>Royal National Theatre British theatre company. It was formed in  1962 as the National Theatre with Laurence Olivier as director (1963-73)  and included many actors from the Old Vic company. In 1976 the com�  pany moved from London�s Old Vic Theatre to a newly constructed three-  theatre complex on the southern bank of the Thames. In 1988 Queen  Elizabeth II gave the company permission to add �Royal� to its name.  Partly subsidized by the state, the theatre presents a mixed classic and  modern repertoire. Its directors have included Peter Hall (1973-88), Rich�  ard Eyre (1988-97), Trevor Nunn (1997-2003), and Nicholas Hytner  (from 2003).</p><p>Royal Navy Naval branch of the armed forces of the United Kingdom.  Organized sea power was first used in England by Alfred the Great, who  launched ships to repel a Viking invasion. In the 16th century Henry VIII  built a fleet of fighting ships armed with large guns and created a naval  administration. Under Elizabeth I the navy developed into Britain�s major  defense and became the means for extending the British Empire around  the globe. The maritime forces were given the name Royal Navy by  Charles II. In the 18th century it engaged in a long struggle with the French  for maritime supremacy, and it later played a key role in Britain�s stand  against Napoleon. For the rest of the 19th century, it helped enforce what  became known as the Pax Britannica, the long period of relative peace in  Europe that depended on British maritime supremacy. It remained the  world�s most powerful navy until the mid-20th century, and it was active  in protecting shipping from submarine attack in World Wars I and II.  Today it maintains four fighting forces: conventional and nuclear-armed  submarines, various surface vessels, naval aircraft, and the Royal Marines.  Officers are trained at the Britannia Royal Naval College, Dartmouth,  Devon. At the start of the 21st century some 42,000 personnel were in  service.</p><p>Royal Shakespeare Company (RSC) Major British theatrical  company. It was originally attached to the Shakespeare Memorial Theatre  in Stratford-upon-Avon, which opened in 1879 as the site of an annual  festival of William Shakespeare�s plays. The resident company was called  the Shakespeare Memorial Company until 1961, when it was renamed  and reorganized into two units, one to play at Stratford and the other to  be based in London. The Stratford unit performs plays by Shakespeare  and other Elizabethan and Jacobean playwrights, while the London unit  also performs modern plays and classics of other eras. Plays are produced  in Newcastle as well.</p><p>Royal Society (of London for Improving Natural Knowl�  edge) Leading scientific society in Britain and the oldest national sci�  entific society in the world. Founded in 1660, its early members included  Robert Hooke, Christopher Wren, Isaac Newton, and Edmond Halley. It has  long provided an impetus to scientific thought and research in the U.K.,  and its achievements have become internationally famous. The society�s  Philosophical Transactions, the oldest scientific periodical in continuous  publication, has published papers since 1665. The society awards several  prizes, the most prestigious being the Copley Medal. At the beginning of  the 21st century, the society had some 1,300 fellows and 130 foreign  members.</p><p>Royall \'roi-9l\, Anne Newport orig. Anne Newport (b. June 11,  1769, New Baltimore, Md.�d.

Nov. 20, 1855, Grass Valley, Calif., U.S.�d. Sept.  14, 1916, Cambridge, Mass.) U.S. philosopher. He studied under William  James and Charles Sanders Peirce at Johns Hopkins University. After  teaching English at the University of California for four years, he accepted  a position at Harvard University (1882), where he remained until his  death. An absolute idealist in the Hegelian tradition, he stressed the unity  of human thought with the external world. His idealism also extended to  religion, the basis of which he conceived to be human loyalty. In his  words, the highest good would be achieved by �the willing and practical  and thoroughgoing devotion of a person to a cause.� A diverse thinker,  he also made contributions to psychology, social ethics, literary criticism,  history, and metaphysics. His many books include The Religious Aspect  of Philosophy (1885), The Spirit of Modern Philosophy (1892), Studies  of Good and Evil (1898), The World and the Individual (1900-01), and  The Philosophy of Loyalty (1908). His emphasis on individuality and will  over intellect strongly influenced 20th-century American philosophy.</p><p>Royko, Mike orig. Michael Royko (b. Sept. 19, 1932, Chicago, Ill.,  U.S.�d.

In 1959  he joined the Chicago Daily News, becoming a full-time columnist in  1964. His irreverent, acerbic, and insightful political and social essays  reflected his working-class ethnic origins, often exposing injustices vis�  ited on ordinary people. He later moved to the Chicago Sun-Times and  then to the Chicago Tribune. His widely syndicated column earned him  a Pulitzer Prize in 1972.

Natural rubber is still  important industrially, but it now competes with synthetic alternatives  (e.g., neoprene, silicone) derived from petroleum, natural gas, and other  source materials. Rubber�s usefulness is based on the unique elasticity of  its constituent polymer molecules (built of thousands of isoprene mono�  mers; see isoprenoid), which are capable of returning to their original coiled  shape after being stretched to great extents; it is made more durable by  vulcanization with sulfur or another agent that establishes chemical cross�  links between the polymers. Fillers and other additives allow tailoring of  properties to the desired use (e.g., by foaming, shaping, and curing). More  than half of all rubber goes into making tires; the rest is used principally  in belts, hoses, gaskets, shoes, clothing, furniture, and toys.</p><p>rubber plant or India rubber plant Tropical tree ( Ficus elastica)  of the mulberry family. The rubber plant is large in its native Southeast Asia  and other warm areas; elsewhere it is commonly grown indoors as a pot�  ted plant. The plant has large, thick, oblong leaves and pairs of figlike  fruits along its branches. The milky sap, or latex, was once an important  source of an inferior natural rubber. Young plants available in the florist�s  trade are durable and grow well under less-than-ideal indoor conditions.  Some cultivated varieties have broader, darker green leaves; others are  variegated. See also rubber tree.</p><p>rubber tree South American tropical tree (Hevea brasiliensis ) of the  spurge family. Cultivated on plantations in the tropics and subtropics,  especially in Southeast Asia and western Africa, it replaced the rubber plant  in the early 20th century as the chief source of natural rubber. It has soft  wood, high, branching limbs, and a large area of bark. The milky liquid  (latex) that oozes from any wound to the tree bark contains about 30%  rubber, which can be coagulated and processed into solid products such  as tires. Latex can also be concentrated for producing dipped goods such  as surgical gloves.</p><p>rubella \rii-'be-l3\ or German measles Viral disease with a usually  mild course, except in women in the first 20 weeks of pregnancy, in whom  it can cause fetal birth defects (of eyes, heart, brain, and large arteries) or  death.

Rubella was not distin�  guished from measles (rubeola) until the early 19th century and was not  known to be dangerous until 1941. The virus was isolated in 1962, and a  vaccine became available in 1969.</p><p>Rubens, Peter Paul (b. June 28, 1577, Siegen, Westphalia�d. May  30, 1640, Antwerp, Spanish Neth.) Flemish painter and diplomat. After  apprenticeships in Antwerp, he was admitted to its painters� guild in 1598.  He went to Italy in 1600 and until 1608 worked for the duke of Mantua,  who in 1603 sent him to Spain to present paintings and other gifts to Philip  III, the first of many diplomatic missions he would perform for various  courts over three decades. The enormous fame he would achieve made  him welcome at royal courts, and sovereigns often discussed affairs of  state while they sat for portraits. Returning to the Spanish Netherlands  (now Belgium) in 1608, he was appointed court painter to the Spanish  Habsburg regents, and over the next decade produced numerous altar-  pieces. A devout Catholic, he became the Counter-Reformation�s chief  artistic proponent in northern Europe. In 1620 he contracted to design 39  ceiling paintings for the Jesuit church, to be completed by assistants,  including the young Anthony Van Dyck. In France he did 21 large can�  vases for Marie de Medicis and a tapestry cycle for Louis XIII; for Britain  his Allegory of Peace and War (1629-30) commemorated the success of  his own diplomatic efforts to end hostilities between Britain and Spain,  and he decorated the royal Banqueting House for Charles I; in Spain he  did more than 60 oil sketches for Philip IV� s hunting lodge. Both Charles  and Philip knighted him. His output was prodigious. He was the greatest  exponent of Baroque painting�s dynamism, vitality, and sensual exuber�  ance. His profound stylistic influence extended over three centuries.</p><p>rubeola See measles</p><p>Rubicon \ , rii-bi- l kan\ Small stream that separated Cisalpine Gaul from  Italy in the era of the Roman republic.

After  several years of study, in 1848 he  settled in St. Petersburg, where in  1862 he founded the St. Petersburg  Conservatory and thereafter devoted  much energy to improving the qual�  ity of Russian musical education. His  once popular compositions, includ�  ing six symphonies, five piano con�  certos, and many chamber works and  piano pieces (including �Melody in  F�) have largely disappeared from  the repertoire.

He later studied with Ignacy Jan Paderewski as  well and performed with moderate success. After some years accompany�  ing the violinist Eugene Ysaye (1858-1931), he stopped performing for  five years (1932-37) to improve his technique and reemerged as a giant of  20th-century music. Moving to the U.S., he became equally noted as soloist  and chamber musician, with such partners as Jascha Heifetz and Gregor  Piatigorsky (1903-76). Active through his 80s, his repertoire ranged from  Johann Sebastian Bach to 20th-century Spanish composers; his playing of</p><p>W Frederic Chopin and Johannes Brahms was particularly admired.</p><p>&#x25A0;s Rubinstein, Helena (b.

His early work was  in the Neoclassical tradition, but he was uncomfortable within its restric�  tions and soon adopted a dynamic, emotional style that might be called  Romantic-Realist. An ardent Bonapartist, he is best known for Departure  of the Volunteers of 1792 (1833-36) on the Arc de Triomphe; popularly  called La Marseillaise, it catches the martial spirit of the Napoleonic era.</p><p>Rudolf (b.

The son of Emperor Francis Joseph, he received a broad  education and traveled widely. As heir to the throne of Austria-Hungary,  he hoped to bring reform to the empire, but his liberal views alienated his  father, and he was excluded from the business of government. From 1881  he considered having himself crowned king of Hungary and reviving a  kingdom of Poland. He then became despondent and allegedly formed a  suicide pact with his mistress, Maria Vetsera; the two were found shot  dead in the hunting lodge at Mayerling. Efforts to disguise the facts pro�  voked many rumours, while romantic writers found inspiration in the  story.</p><p>Rudolf I or Rudolf of Habsburg (b. May 1, 1218, Limburg-im-  Breisgau�d.

Crowned  king in 1273, he was recognized by Pope Gregory X only after promis�  ing to lead a new Crusade and to renounce imperial rights in Rome, the  papal territories, and Italy. Rudolf defeated his rival Otakar II (1276,  1278) and gained lands in Austria, which he granted to his sons. He  worked to combat the expansionist policies of France, but French influ�  ence at the papal court kept him from being crowned Holy Roman  emperor. Although he created the core of later Habsburg territorial power,  Rudolf was unable to make the throne a hereditary possession of his fam�  ily, because the German electors would not raise his son to the kingship.</p><p>Rudolf, Lake or Lake Turkana Lake, mainly in northern Kenya.

Among the ornamentals are  common rue (Ruta graveolens) and  the unusual burning bush, or gas  plant, ( Dictamnus albus), whose aro�  matic leaves contain oil glands that,  when squeezed, release a gas ignit-  able by a match.</p><p>ruffed grouse North American  species (. Bonasa umbellus) of GROUSE,  sometimes incorrectly called a partridge. Ruffed grouse live mainly on  berries, fruits, seeds, and buds but also eat much animal food. They are  16-20 in. (40-50 cm) long and have feathered lower legs and a black  band on the fan-shaped tail. The male�s ruff consists of erectile black  feathers on the sides of the neck. Males beat their wings rapidly against  the air (called drumming) to proclaim their territory.</p><p>Ruffin, Edmund (b. Jan. 5, 1794, Prince George county, Va., U.S.�d.  June 18,1865, Amelia county, Va.)U.S. agriculturist and secessionist. Edu�  cated largely at home, he managed his father�s tobacco plantation from  1813. He found that overuse and poor farming methods produced an acid  soil unable to retain fertilizers; in 1832 he published an influential book  advocating the use of marl to reduce soil acidity, which helped restore  Southern plantations to productivity. He also published the Farmer�s Reg�  ister (1833-42) and lectured widely on agriculture. In the 1850s he  defended slavery and advocated secession. He fired one of the first shots at  Fort Sumter (1861). Unable to accept the South�s defeat, he killed himself.</p><p>rug and carpet Any decorative textile normally made of a thick mate�  rial and intended as a floor covering. Floor coverings made of plaited  rushes date from the 5th or 4th millennium bc. Carpets were first made  in central and western Asia as coverings for earthen floors; they were also  used for blankets, saddle covers, storage bags, tent doorways, and tomb  covers. Oriental carpets imported into Europe in the 16th� 17th century  were considered too valuable to be put on the floor and were often used  as wall decoration. They are still popular wall decorations in Russia. Car�  pet weaving reached its peak of artistry in 16th-century Persia. In the  West, outstanding carpets were produced at factories in 17th-century  France and 18th-century England. Most handmade carpets are made from  sheep�s wool. Natural dyes were used until the 19th century, when chemi�  cal dyes were introduced. See also Aubusson carpet; Axminster carpet.</p><p>rugby Football sport made up of two variant codes�rugby union and  rugby league. The sport was first developed in the 1820s at Rugby School  in England. In 1895 a dispute over professionalism between the Rugby  Football Union and several clubs in northern England led to the creation of  rugby league (always a professional sport). Rugby union became fully pro�  fessional in 1995. The game is played by teams of 15 (union) or 13 (league)  members each, using an inflated oval ball. The ball may be kicked, carried,  or passed laterally or backward (but not forward). The object is to score  goals (worth three points) by kicking the ball between the uprights of the  opponent�s goal, or tries (worth five points in union play, four in league), by  grounding the ball behind the opponent�s goal line. A conversion kick  (worth two points) is attempted after scoring a try. Both rugby union and  rugby league have international play and world cup tournaments. Rugby is  most popular in the United Kingdom, South Africa, Australia, and New  Zealand.</p><p>Ruhr occupation (1923-25) Occupation of the industrial Ruhr River  valley region in Germany by French and Belgian troops. The action was  provoked by German deficiencies in the coal and coke deliveries to France  required by the reparations agreement after World War I. French occupa�  tion of Diisseldorf, Duisburg, and Ruhrort in 1921 was followed by  French-Belgian occupation of the entire region in 1923. Passive resistance  by German workers paralyzed the Ruhr�s economy and precipitated the  collapse of the German currency. The dispute was settled by the Dawes  Plan, and the occupation ended in 1925.</p><p>Ruhr Vrur\ River River, western Germany. An important tributary of  the lower Rhine River, it rises on the northern side of Winterberg and flows  146 mi (235 km) west. The Ruhr valley is a major industrial and mining  region; it includes the industrial cities of Essen, Diisseldorf, and Dortmund.  The Ruhr coalfield is one of the world�s largest and produces the bulk of  Germany�s bituminous coal. Industries begun by the Krupp and Thyssen  families flourished in the 19th-20th centuries (see Thyssen-Krupp Stahl).  The river was militarily important in World War I, and the river valley  was occupied from 1923 to 1925 by France and Belgium (see Ruhr occu�  pation). As the industrial heart of Nazi Germany, it was heavily bombed  in World War II and occupied by Allied troops in 1945; full control was  returned to West Germany in 1954. It is now a centre of steel production  and diversified chemical manufacturing.</p><p>Ruisdael Vrois-.dalV Jacob (Isaakszoon) van also spelled Ruys-  dael (b. 1628/29, Haarlem, Neth.�buried March 14, 1682, Amsterdam)  Dutch landscape painter. He was probably trained by his father, a frame-  maker and artist. He was enrolled in the Haarlem painters� guild in 1648  and settled in Amsterdam c. 1656. He was a remarkably versatile artist, and  some 700 paintings have been attributed to him. Whereas earlier Dutch art�  ists used trees merely as decorative devices, Ruisdael made them the sub�  ject of his paintings and imbued them with forceful personalities through  vigorous brushwork and strong colours in the Baroque style. The emotional  force of his work is evident in the famous Jewish Cemetery (c. 1660),  where three tombstones crumble to ruin amid an ever-renewing nature. His  late works include numerous panoramas of the flat Dutch countryside, in  which a low, distant horizon is dominated by a vast, clouded sky. He is  often considered the greatest Dutch landscape painter of all time.</p><p>Ruisdael, Salomon van See Salomon van Ruysdael</p><p>Ruiz \ru-'eth\, Juan (b. c. 1283, Alcala, Spain�d. c. 1350) Spanish poet  and cleric. Educated at Toledo, Ruiz was serving as a village archpriest  when he finished his masterpiece, The Book of Good Love (1330,  expanded 1343). Perhaps the most important long poem in medieval Span�  ish literature, it contains 12 narrative poems, each describing a different  love affair. Its title refers to the distinction the author makes between the  (good) love of God and carnal love. Drawing on material from an impres�  sive range of literary and other sources, it presents a vigorous, high-  spirited, satirical glimpse of medieval life.</p><p>Rukwa Vrii-kwaV, Lake Shallow lake, southwestern Tanzania, eastern  Africa. It covers an area of about 1,000 sq mi (2,600 sq km) and lies mid�  way between Lake Tanganyika and Lake Malawi (Nyasa) at an elevation  of about 2,600 ft (800 m). It has no outlet, and at times it is completely  dry. Its water is brackish, and there are salt pans near its southwestern  end. Crocodiles and hippopotamuses inhabit the lake, and fish abound.</p><p>Rule of the Community See Manual of Discipline  rules of order See parliamentary procedure</p><p>rum Distilled liquor made from sugarcane products, primarily molasses. It  is first mentioned in records from Barbados c. 1650. Rum figured in the  slave trade: slaves from Africa were traded in the West Indies for molasses,  the molasses was made into rum in New England, and the rum was then  traded to Africa for more slaves. British sailors received regular rum rations  from the 18th century until the 1970s. Two major types are marketed. The  light-bodied rums, traditionally of Puerto Rico and Cuba, employ culti�  vated yeast and are distilled in continuous-operation stills before being  blended and aged one to four years. The heavier dark rums, traditionally of  Jamaica, employ yeast spores from the air and are distilled in simple pot  stills before being blended and aged five to seven years. Rum is drunk  straight or mixed and is used in dessert sauces and other dishes.</p><p>Rumania See Romania</p><p>Rumi \'ru-,me\ in full Jalal al-DTn al-Rumi byname Mawlana  (Arabic: "Our Master") (b. c.

Dec. 17, 1273, Konya, Anatolia) The greatest Sufi mystic and  among the most renowned Persian poets. He was a teacher at a madrasah  in Anatolia when he met Shams al-Dln (�Sun of Religion�), a wandering  dervish who revealed to him the inner mysteries of divine majesty; their  intimate relationship scandalized Rumi�s followers, who likely had Shams  al-Dln murdered. The disappearance of his companion turned RumI to  poetry, and his Dlvdn-e Shams (�Collected Poetry of the Sun�) contains  verses on his love and longing for Shams al-Dln. His main work, the  didactic epic Masnavl-ye Ma'navl (�Spiritual Couplets�), widely influ�  enced Muslim mystical thought and literature. He is believed to have  composed poetry while in a state of ecstasy and often accompanied his  verses by a whirling dance. After his death, his disciples were organized  as the Mawlawiyyah (Mevlevi), a Sufi order called in the West the �whirl�  ing dervishes,� and his influence on Turkish culture is inestimable. His  poems, originally in Persian, have been translated into a number of lan�  guages, including English, and have enjoyed a worldwide following into  the modem period.</p><p>ruminant Vrii-mo-nonA Any cud-chewing ungulate, including antelope,  CAMELS, CATTLE, DEER, GIRAFFES, GOATS, OKAPIS, PRONGHORN, and SHEEP. Most  ruminants have a four-chambered stomach, two-toed feet, and small or  absent upper incisors. Camels and chevrotains have three-chambered  stomachs. Ruminants eat quickly, storing masses of grass (grazers) or  foliage (browsers) in the first stomach chamber, the rumen, where it soft�  ens. They later regurgitate the material, called cud, and chew it again to  break down the undigestible cellulose. The chewed cud goes directly to  the other chambers, where various microorganisms help in its digestion.</p><p>rummy Family of card games. The many variants of rummy make it  one of the world�s best-known and most widely played card games. The  basic principle of rummy (also spelled rum, rhum, or romme) is to form  sets of three or four cards of the same rank (as four 8s, three 6s) or  sequences of three or more cards of the same suit (6�5�4�3, all of dia�  monds, e.g.). Canasta is an unusual type of rummy, in that sequences are  not permitted. See also gin rummy.</p><p>Rundstedt \'runt-,shtet\, (Karl Rudolf) Gerd von (b.

Chief of staff of an army  corps in World War I, he was active after the war in Germany�s secret  rearmament. In World War II he was promoted to field marshal (1940)  and commanded armies in the invasions of Poland, France, and the Soviet  Union. As commander in chief on the Western Front (1942-45), he for�  tified France against the expected Allied invasion. Removed briefly from  command (1944), he returned to direct the Battle of the Bulge. He was  captured in 1945 but released because of ill health.</p><p>rune Any of the characters within an early Germanic writing system.  The runic alphabet, also called futhark, is attested in northern Europe,  p_ Britain, Scandinavia, and Iceland from about the 3rd century to the 16th</p><p>or 17th century ad. The Goths may have developed it from the Etruscan  wm alphabet of northern Italy. More than 4,000 runic inscriptions and several</p><p>ifl runic manuscripts are extant.

Feb. 5, 1804, Jakobstad,  Swedish Finland�d. May 6, 1877, Borga, Russian Finland) Finnish poet  who wrote in Swedish. During an interruption in his academic career, he  became a tutor at a country estate, where he encountered Finland�s land�  scape and tales of the heroic past. His works, combining classicism with  Romantic feeling and an understanding of peasant life and character,  include the epic poems The Moose Hunters (1832) and Hanna (1836),  which won him a place in Swedish letters; and Kung Fjalar, a cycle of  romances derived from old legends. His patriotic poem �Our Country,�  from Tales of Ensign Stdl (1848, 1860), became the Finnish national  anthem. Runeberg is considered Finland�s national poet.</p><p>runic writing or futhark Vfu-,thark\ Writing system used by Ger�  manic peoples of northern Europe, Britain, Scandinavia, and Iceland from  roughly the 3rd to the 16th or 17th century ad. Of uncertain origins, it is  clearly derived from one of the alphabets of the Mediterranean area. Three  main varieties were used in different regions and time periods: Early, or  Common Germanic (Teutonic); Anglo-Saxon, or Anglian; and Nordic, or  Scandinavian.

After return�  ing to the U.S. he wrote for newspapers in the West. In 1911 he moved  to New York, where he developed a style focusing on the underside of  city life and began to write stories. He is best known for Guys and Dolls  (1931), a collection of stories about a racy section of Broadway written  in the uniquely rendered slang that became his trademark and gave rise  to the term Runyonesque\ the book was adapted as a musical by Frank  Loesser (1950).</p><p>rupa-loka Vrii-po-'lo-koV In Buddhism, any of the 16 planes of existence  into which those beings who have renounced sense desires are reborn. It  is intermediate between the kama-loka, where material beings are born,  and the arupa-loka, where only the mind exists. Its upper levels are called  the Pure Abodes, the birthplace of those beings who do not return to lower  planes in subsequent births. The rupa-loka, free from sensuous desire but  still conditioned by form, is inhabited by gods. See also karma.</p><p>Rupert, Prince (b. Dec. 17, 1619, Prague, Bohemia�d. Nov. 29, 1682,  Fondon, Eng.) Royalist commander in the English Civil Wars. Son of the  Palatine elector Frederick V and Elizabeth, daughter of James I of England,  Rupert became a favourite of his uncle, Charles I, whom he joined in  England in 1642. In the English Civil Wars, he was given command of  the cavalry and became known for his daring tactics in winning victories  at Bristol (1643) and in Fancashire (1644). He met defeat at the Battle of  Marston Moor but was appointed commander of the king�s army. When  he surrendered Bristol (1645), he was dismissed and then banished from  England. He commanded a small Royalist fleet that preyed on English  shipping (1648-50), then retired to Germany (1653-60). With the Resto�  ration (1660), he was given naval commands in the Anglo-Dutch Wars.  He was a founder and first governor of the Hudson's Bay Co.</p><p>Rupert's Land or Prince Rupert's Land Historical region, north�  ern and western Canada, comprising the drainage basin of Hudson Bay.

It flows  150 mi (240 km) to join the Hugli River. It originally formed a western exit  of the Ganges River and is important for its irrigation potential.</p><p>rural electrification Project of the U.S. government in the 1930s. As  part of the New Deal, the Rural Electrification Administration (REA) was  established (1935) to bring electric power to farms, thereby raising the  standard of rural living and slowing the migration of farm workers to cit�  ies. Providing low-interest loans to construct power plants and power lines  to rural areas, the project eventually equipped over 98% of U.S. farms  with electricity.</p><p>Rurik or Rorik (d. 879) Semilegendary founder of the Rurik dynasty  of Kievan Rus. He was a Viking (Varangian) prince. According to one  12th-century Russian chronicle, the people of Novgorod invited him to  take over their strife-ridden government (c. 862). Other historians think  that he conquered Novgorod or that he and his army were rebellious mer�  cenaries.

As a doctor,  he was a dogmatic theorist who proposed that all diseases are fevers  caused by overstimulation of blood vessels, with a simple remedy�  bloodletting and purges. He advocated humane treatment for insane  patients; his idea that insanity often had physical causes marked a sig�  nificant advance. He wrote the first chemistry textbook and the first psy�  chiatry treatise in the U.S. An early and active American patriot and a  member of the Continental Congress, Rush drafted a resolution urging  independence and signed the Declaration of Independence.</p><p>Rush, Richard (b.

The son of Benjamin Rush, he served as  U.S. attorney general (1814-17) and secretary of the treasury (1825-29).  As acting secretary of state (1817), he negotiated the Rush-Bagot Agree�  ment with Britain, which limited naval forces on the Great Lakes after the  War of 1812. As U.S. minister to Britain (1817-25), he negotiated an agree�  ment fixing the border between Canada and the U.S. at the 49th parallel. In  conferences on Latin America, he helped formulate the Monroe Doctrine.  In 1836, as the U.S. agent in London, he received the bequest by which  James Smithson founded the Smithsonian Institution; Rush considered his  role in founding the museum his most important public service.</p><p>Rushdie \'rush-de,\ commonly Vrosh-deV, (Ahmed) Salman (b.

Educated at the Uni�  versity of Cambridge, he worked as an advertising copywriter in London  in the 1970s before winning unexpected success with Midnight�s Chil�  dren (1981, Booker Prize), an allegorical novel about modem India. His  second novel, Shame (1983), is a scathing portrait of politics and sexual  morality in Pakistan. The Satanic Verses (1988), which includes among  its bizarre happenings some episodes based on the life of Muhammad, was  denounced as blasphemous by outraged Muslim leaders, and in 1989  Rushdie was condemned to death by Iran�s Ruhollah Khomeini.

He  thereafter led his own small groups or worked with the bands of Benny  Goodman, Buck Clayton, and occasionally Basie. Rushing�s full tenor  voice, although associated with the blues-based repertoire of the Basie  period, was also well suited to popular songs and ballads.</p><p>Rusk, (David) Dean (b.

He earned a master�s degree as a Rhodes scholar at St. John�s Col�  lege, Oxford, and then taught (1934-40) at Mills College in Oakland,  Calif. He served in World War II on Gen. Joseph Stilwell�s staff. He later  held positions in the U.S. State Department and War Department, help�  ing prosecute the Korean War as an assistant secretary of state (1950).  After serving as president of the Rockefeller Foundation (1952-60), he  became U.S. secretary of state under John F. Kennedy and Lyndon B.  Johnson. A consistent defender of U.S. participation in the Vietnam War,  he became a target of antiwar protests. He also opposed diplomatic rec�  ognition of China.

Born into a wealthy family, Ruskin  was largely educated at home. He was a gifted painter, but the best of his  talent went into his writing. His multivolume Modern Painters (1843�  60), planned as a defense of painter J.M.W. Turner, expanded to become  a general survey of art. In Turner he saw �truth to nature� in landscape  painting, and he went on to find the same truthfulness in Gothic architec�  ture. His other writings include The Seven Lamps of Architecture (1849)  and The Stones of Venice (1851-53). He was also a defender of the Pre-</p><p>Raphaelites. In 1869 he was elected Oxford�s first Slade professor of fine  art; he resigned in 1879 after James McNeill Whistler won a libel suit  against him. In later years he used his inherited wealth to promote ide�  alistic social causes, but his powerful rhetoric, which still contained strik�  ing insights, became marred by bigotry and occasional incoherence.  Ruskin remains the preeminent art critic of 19th-century Britain.</p><p>Russell, Bertrand (Arthur William), 3rd Earl Russell (b. May</p><p>18, 1872, Trelleck, Monmouthshire,</p><p>Eng.�d. Feb. 2,1970, near Penrhyn-  deudraeth, Merioneth, Wales) British  logician and philosopher. He is best  known for his work in mathematical  logic and for his advocacy on behalf  of a variety of social and political  causes, especially pacifism and  nuclear disarmament. He was born  into the British nobility as the grand�  son of Earl Russell, who was twice  prime minister of Britain in the mid-  19th century. He studied mathemat�  ics and philosophy at Cambridge  University, where he came under the  influence of the idealist philosopher  J.M.E. McTaggart, though he soon  rejected idealism in favour of an  extreme Platonic realism. In an early  paper, �On Denoting� (1905), he  solved a notorious puzzle in the phi�  losophy of language by showing how  phrases such as �The present king of France,� which have no referents,  function logically as general statements rather than as proper names. Rus�  sell later regarded this discovery, which came to be known as the �theory  of descriptions,� as one of his most important contributions to philosophy.  In The Principles of Mathematics (1903) and the epochal Principia Math-  ematica (3 vol., 1910�13), which he wrote with Alfred North Whitehead, he  sought to demonstrate that the whole of mathematics derives from logic.  For his pacifism in World War I he lost his lectureship at Cambridge and  was later imprisoned. (He would abandon pacifism in 1939 in the face of  Nazi aggression.) Russell�s best-developed metaphysical doctrine, logical  atomism, strongly influenced the school of logical positivism. His later philo�  sophical works include The Analysis of Mind (1921), The Analysis of Mat�  ter (1927), and Human Knowledge: Its Scope and Limits (1948). His A  History of Western Philosophy (1945), which he wrote for a popular audi�  ence, became a best-seller and was for many years the main source of his  income. Among his many works on social and political topics are Roads to  Freedom (1918); The Practice and Theory of Bolshevism (1920), a scathing  critique of Soviet communism; On Education (1926); and Marriage and  Morals (1929). In part because of the controversial views he espoused in  the latter work, he was prevented from accepting a teaching position at the  City College of New York in 1940. After World War II he became a leader  in the worldwide campaign for nuclear disarmament, serving as first presi�  dent of the international Pugwash Conferences on nuclear weapons and  world security and of the Campaign for Nuclear Disarmament. In 1961, at  the age of 89, he was imprisoned for a second time for inciting civil dis�  obedience. He received the Nobel Prize for Literature in 1950.</p><p>Russell, Bill in full William Felton Russell (b. Feb. 12, 1934, Mon�  roe, La., U.S.) U.S. basketball player. The 6-ft 10-in.

Playing for the Boston Celtics (1956-69), Russell led his team to 11 NBA  championships in 13 seasons�the last 2 as coach, having become in 1967  the first black coach of a major professional sports team. Russell�s career  mark for rebounds (21,620) is second only to that of his great rival Wilt  Chamberlain, and he is regarded as one of the finest defensive centres of  all time.

A member of the prominent Russell family, he entered Parliament in 1813.  He was a strong advocate of reform and made it a cause of the Whig Party,  leading the effort to pass the Reform Bill of 1 832. He served in Viscount  Melbourne�s government as home secretary (1835), reducing the number  of crimes liable to capital punishment and beginning state support of pub�  lic education. In the 1840s he advocated free trade and forced Robert Peel  out of office. Russell became prime minister in 1846 and established the  10-hour day in factories (1847) and a board of public health (1848), but  party disunity defeated his attempts at wider social and economic reform.</p><p>Russell, Lillian orig. Helen Louise Leonard (b. Dec. 4, 1861,  Clinton, Iowa, U.S.�d. June 6, 1922, Pittsburgh, Pa.) U.S. singer and  actress. She made her stage debut while still in her teens. She achieved  stardom in Grand Mogul (1881) and later won acclaim in The Grand  Duchess (1890). From 1899 to 1904 she appeared in England and the U.S.  with a burlesque company. Representing the feminine ideal of her gen�  eration, she was as famous for her flamboyant personal life as for her  hourglass figure, her beauty, and her voice. After her fourth marriage in  1912, she wrote a syndicated column on health, beauty, and love and lec�  tured on these topics before vaudeville audiences.</p><p>Russell, William Russell, Lord (b. Sept. 29,1639�d. July 21,1683,  London, Eng.) English Whig politician. A member of the House of Com�  mons, he joined the opposition to the pro-French policies of Charles II. In  1678 he was convinced by Titus Oates�s fabricated Popish Plot, and by 1680  he led the fight in the Commons to exclude Charles�s brother James (later  James II) from the succession. After Charles dissolved Parliament (1681),  Russell continued to associate with Whig dissidents. In 1683 he was  accused of participating in the Rye House Plot to murder Charles. The  charges were never proved, but Russell was found guilty of treason and  beheaded.</p><p>Russell Cave National Monument National Monument, north�  eastern Alabama, U.S. Located south of the Alabama-Tennessee border,  the monument constitutes part of a cavern that was discovered c. 1953.  The cave is about 210 ft (64 m) long, 107 ft (33 m) wide, and 26 ft (8 m)  high. It contains an almost continuous record of human habitation dating  to at least 7000 bc. The national monument was established in 1961.</p><p>Russell family English Whig family. It first became prominent under  the Tudors, when John Russell (died 1555) was created earl of Bedford  (1549) for helping suppress a rebellion against the Protestant reforms of  Edward VI. The family was connected with the Parliamentary party in the  English Civil Wars. Its first notable Whig member was William, Lord Rus�  sell. Later members included John, Earl Russell, and his grandson, the phi�  losopher Bertrand Russell.</p><p>Russia officially Russian Federation Country, eastern Europe and  northern Asia, formerly the preeminent republic of the Union of Soviet  Socialist Republics. Area: 6,592,800 sq mi (17,075,400 sq km). Population  (2005 est.): 143,420,000. Capital: Moscow. The population is primarily  Russian; minorities include Tatars and Ukrainians. Languages: Russian  (official), various Turkic and Uralic languages. Religions: Christianity  (mostly Eastern Orthodox, also Protestant); also Islam. However, about  one-third of the people are nonreligious or atheist. Currency: ruble. The  land and its environments are varied, including the Ural Mountains and  ranges in eastern Siberia, the highest peaks being on the Kamchatka Pen�  insula. The Russian Plain contains the great Volga and Northern Dvina  rivers, and in Siberia are the valleys of the Ob, Yenisey, Lena, and Amur  rivers. Tundra covers extensive portions in the north, and in the south there  are forests, steppes, and fertile areas. The economy was industrialized  from 1917 to 1945 but was in serious decline by the 1980s. In 1992 the  government decreed radical reforms to convert the centrally planned  economy into a market economy based on private enterprise. Russia is a  federal republic with a bicameral legislative body; its head of state is the  president, and the head of government is the prime minister.

Kievan Rus, a confederation of prin�  cipalities ruling from Kiev, emerged c. the 10th century; it lost supremacy  in the 11 th� 12th century to independent principalities, including  Novgorod and Vladimir. Novgorod ascended in the north and was the  only Russian principality to escape the domination of the Mongol Golden  Horde in the 13th century. In the 14th�15th century the princes of Mos�  cow gradually overthrew the Mongols. Under Ivan IV (the Terrible), Rus�  sia began to expand. The Romanov dynasty arose in 1613. Expansion  continued under Peter I (the Great) and Catherine II (the Great). The area  was invaded by Napoleon in 1812; after his defeat, Russia received most  of the Grand Duchy of Warsaw (1815). Russia annexed Georgia, Arme�  nia, and Caucasus territories in the 19th century. The Russian southward  advance against the Ottoman Empire was of key importance to Europe (see  Crimea). Russia was defeated in the Crimean War (1853-56). Chinese ces�  sion of the Amur River�s left bank in 1858 marked Russia�s expansion in  East Asia. Russia sold Alaska to the U.S. in 1867 (see Alaska Purchase).  Defeat in the Russo-Japanese War led to an unsuccessful uprising in 1905  (see Russian Revolution of 1905). In World War I Russia fought against  the Central Powers. The popular overthrow of the tsarist regime in 1917  marked the beginning of a government of soviets (see Russian Revolution  of 1 917). The Bolsheviks brought the main part of the former empire under  communist control and organized it as the Russian Soviet Federated  Socialist Republic (coextensive with present-day Russia). The Russian  S.F.S.R. joined other soviet republics in 1922 to form the U.S.S.R. Upon  the dissolution of the U.S.S.R. in 1991, the Russian S.F.S.R. was renamed  and became the leading member of the Commonwealth of Independent  States. It adopted a new constitution in 1993. During the 1990s and into  the early 21st century, it struggled on several fronts, beset with economic  difficulties, political corruption, and independence movements (see Chech�  nya).

The Moscow gov�  ernment responded to the growing anti-Bolshevik movement by expelling  Menshevik and Social Revolutionary deputies from the government, and  it began a campaign of �Red terror� that gave increased powers to the  secret police (Cheka) to arrest and execute suspects. The Bolsheviks main�  tained control over the heart of the country, but the anti-Bolsheviks gained  power in Ukraine and Omsk, where Aleksandr Kolchak and other dissi�  dent groups joined together to fight the Red Army. Confused by the  struggles between communists, Russian Whites, and Ukrainian national�  ists, the Allies withdrew their support by 1919. After early military suc�  cesses against the Red Army, the White forces under Kolchak were  defeated by early 1920. Other White troops under Nikolay Yudenich failed  to take St. Petersburg. The last White stronghold in the Crimea under Pyotr  Wrangel, Denikin�s successor, was defeated in November 1920, ending  the Russian Civil War.</p><p>Russian Formalism See Formalism</p><p>Russian language East Slavic language spoken by about 170 million  people in Russia, former republics of the Soviet Union, and emigre com�  munities. For many non-Russian ethnic groups both within and outside  contemporary Russia, it is a common second language and lingua franca.  Since the Middle Ages, Russian has gradually expanded its speech area  from its historical locus in the upper Volga and Dnieper River drainages  northward and eastward. Russian speakers penetrated Siberia in the 16th  century and reached the Pacific in the 17th century. Russian became a  full-fledged literary language in the 18th century, when it finally displaced  Church Slavonic (see Old Church Slavonic language). Dialect differences  in Russian are not great, considering the enormous territory over which  it is spoken, and the upheavals of the 20th century eroded such distinc�  tions as exist.

After several years of mounting discontent, a  peaceful demonstration was crushed by Tsar Nicholas II�s troops in the  Bloody Sunday massacre. General strikes followed in St. Petersburg and  other industrial cities. The revolt spread to non-Russian parts of the  empire, including Poland, Finland, and Georgia. Antirevolutionary  groups, including the Black Hundreds, opposed the rebellion with violent  attacks on socialists and pogroms against Jews. By October 1905, general  strikes had spread to all the large cities, and the workers� councils or sovi�  ets, often led by the Mensheviks, became revolutionary governments. The  strikes� magnitude convinced Nicholas II, advised by Sergey Witte, to  issue the October Manifesto, promising an elected legislature. The con�  cessions satisfied most moderates, though the more ardent revolutionar�  ies refused to yield, and pockets of resistance in Poland, Georgia, and  elsewhere were harshly suppressed as the regime restored its authority.  While most of the revolutionary leaders, including Leon Trotsky, were  arrested, the revolution forced the tsar to institute reforms such as a new  constitution and a Duma, though he failed to adequately implement vari�  ous promised reforms.</p><p>Russian Revolution of 1917 Revolution that overthrew the impe�  rial government and placed the Bolsheviks in power. Increasing govern�  mental corruption, the reactionary policies of Tsar Nicholas II, and  catastrophic Russian losses in World War I contributed to widespread  dissatisfaction and economic hardship. In February 1917 riots over food  scarcity broke out in Petrograd (St. Petersburg). When the army joined  the rebels, Nicholas was forced to abdicate. A provisional government,  headed by Georgy Lvov, was appointed in March and tried to continue  Russia�s participation in World War I, but it was opposed by the power�  ful Petrograd workers� soviet, which favoured Russian withdrawal from  the war. Other soviets were formed in major cities and towns, choosing  members from factories and military units. The soviet movement was  dominated by the Socialist Revolutionary Party, followed by the Menshe�  viks and the Bolsheviks. Between March and October, the provisional  government was reorganized four times; Aleksandr Kerensky became its  head in July; he survived a coup attempt by Lavr Kornilov but was unable  to halt Russia�s slide into political and military chaos. By September the  Bolsheviks, led by Vladimir Lenin, had achieved majorities in the Petrograd  and Moscow soviets and won increasing support among the hungry urban  workers and soldiers. In October they staged a nearly bloodless coup (the  �October Revolution�), occupying government buildings and strategic  points. Kerensky tried unsuccessfully to organize resistance, then fled the  country. The congress of soviets approved the formation of a new gov�  ernment composed mainly of Bolsheviks. See also April Theses; Aleksandr  Guchkov; July Days; Russian Civil War.</p><p>Russian Social-Democratic Workers' Party Marxist revolu�  tionary party that preceded the Communist Party of the Soviet Union.  Founded in Minsk in 1898, it held that Russia could achieve socialism  only after developing a bourgeois society with an urban proletariat. The  party split in 1903 because of the argument between the Bolshevik wing,  led by Vladimir Ilich Lenin, and the Menshevik wing, led by L. Martov, over  Lenin�s proposals for a party composed of professional revolutionaries.  Party members were active in the Russian Revolution of 1905. In the tur�  moil of the Russian Revolution of 1917, the Bolsheviks broke completely  with the Mensheviks and changed their name to �Russian Communist  Party (Bolshevik).�</p><p>Russo-Finnish War or Winter War (1939-40) War waged by the  Soviet Union against Finland at the start of World War II, following the  signing of the German-Soviet Nonaggression Pact. When Finland refused  to grant the Soviets a naval base and other concessions, Soviet troops  attacked on several fronts in November 1939. The heavily outnumbered  Finns under Carl Gustav Emil Mannerheim put up a skillful defense until  February 1940, when heavy Russian bombardments breached the Finns�  southern defenses. A peace treaty in March 1940 ceded western Karelia  to Russia and allowed construction of a Soviet naval base on the Hanko  peninsula.</p><p>Russo-Japanese War (1904-5) Conflict between Russia and Japan  over territorial expansion in East Asia. After Russia leased the strategi�  cally important Port Arthur (now Lushun, China) and expanded into Man�  churia, it faced the increasing power of Japan. When Russia reneged on  its agreement with Japan to withdraw troops from Manchuria, the Japa�  nese fleet attacked the Russia naval squadron at Port Arthur and began a  siege of the city in February 1904. Japanese land forces cut the Russian  army off from coming to aid Port Arthur and pushed it back to Mukden  (now Shenyang). The reinforced Russian army took the offensive in Octo�  ber, but poor military leadership blunted its effectiveness. After the long  Japanese siege of Port Arthur, in January 1905 the corrupt Russian com�  mander surrendered the garrison without consulting his officers, despite  adequate stores and ammunition for its continued defense. Heavy fight�  ing around Mukden ended in March 1905 with the withdrawal of Russian  troops under Aleksey Kuropatkin. The decisive naval Battle of Tsushima gave  the Japanese the upper hand and brought Russia to the peace table. With  the signing of the Treaty of Portsmouth, Russia abandoned its expansion�  ist policy in eastern Asia and Japan gained effective control of Korea and  much of Manchuria.</p><p>Russo-Turkish Wars Series of wars fought between Russia and the  Ottoman Empire from the 17th to the 19th century. Russia waged the early  wars (1676-81, 1686, 1689) in a fruitless attempt to establish a warm-  water port on the Black Sea. In the war of 1695-96, however, Peter I cap�  tured the fortress of Azov, but subsequent attempts (1710-12, 1735-39)  by the Russians to seize the Balkans failed, leading to the Treaty of Bel�  grade. In Catherine ll�s reign the first major Russo-Turkish war (1768-74)  pushed Russian borders south and gave Russia a vague right of protec�  tion over the Ottoman sultan�s Christian subjects. (See also Treaty of  Kucuk Kaynarca.) Catherine annexed the Crimean Peninsula in 1783. Rus�  sia gained the entire western Ukrainian Black Sea coast in the Treaty of  Jassy (1792). A subsequent war (1806-12) led to the Treaty of Bucharest.  In the 19th century wars were fought over the Dardanelles and Bosporus  straits, the Caucasus, and Crimea. The war of 1828-29 ended in the Treaty  of Edirne (1829), which ceded large tracts to Russia. The Crimean War  (1853-56), however, was a major diplomatic setback for Russia. The  1877-78 Russo-Turkish War pitted Russia and Serbia against Turkey over  autonomy for Bosnia and Herzegovina. Russia was victorious, but the  gains it achieved under the Treaty of San Stefano (1878) were restricted  by the Congress of Berlin (1878), imposed by Britain and Austria-Hungary.</p><p>rust, blister See buster rust</p><p>rustication In architecture, decorative masonry achieved by cutting  back the edges of stones to a plane surface while leaving the central por�  tion of the face either rough or projecting markedly.

Italian early Renaissance archi�  tects used rustication to decorate palaces.

After studies at Canterbury  College, he moved to Britain to attend Cambridge University, where he  worked with JJ. Thomson at the Cavendish Laboratory. He would later  teach at McGill University in Montreal (1898-1907) and Victoria Uni�  versity in Manchester (1907-19) before becoming chair of the Cavend�  ish Laboratory (from 1919). At the laboratory in the years 1895-97 he  discovered and named two types of radioactivity, alpha decay and beta  decay. He later identified the alpha particle as a helium atom and used it  in postulating the existence of the atomic nucleus. With Frederick Soddy  he formulated the transformation theory of radioactivity (1902). In 1919  he became the first person to disintegrate an element artificially, and in  1920 he hypothesized the existence of the neutron. His work contributed  greatly to understanding the disintegration and transmutation of radioac�  tive elements and became fundamental to much of 20th-century physics.  In 1908 he was awarded the Nobel Prize. He was knighted in 1914 and  ennobled in 1931.

Area: 10,169 sq mi (26,338 sq km). Population (2005 est.):</p><p>8,574,000. Capital: Kigali. The population is  mostly Hutu, with a Tutsi minority. Lan�  guages: Rwanda, French, English (all offi�  cial). Religions: Christianity (mostly  Roman Catholic; also Protestant); also tra�  ditional beliefs, Islam. Currency: Rwanda franc. Rwanda is a landlocked  mountainous country, most of it at an elevation above 4,000 ft (1,200 m).  There are bamboo forests, wooded regions, and grassy savannas with rich  and varied wildlife. The developing economy is mainly free-enterprise,  based on agriculture. Rwanda is a republic with two legislative bodies; its  head of state and government is the president, assisted by the prime min�  ister. Originally inhabited by the Twa, a Pygmy people, it became home to  the Hutu, who were well established there when the Tutsi appeared in the  14th century. The Tutsi conquered the Hutu and in the 15th century founded  a kingdom near Kigali. The kingdom expanded steadily, but from 1894 to  1918 Rwanda was part of German East Africa. The Belgians occupied  Rwanda in 1916, and the League of Nations created Ruanda-Urundi as a Bel�  gian mandate in 1923. The Tutsi retained their dominance until shortly  before Rwanda reached independence in 1962, when the Hutu took control  of the government and stripped the Tutsi of much of their land. Many Tutsi  fled Rwanda, and the Hutu dominated the country�s political system, wag�  ing sporadic civil wars until mid-1994, when the death of the country�s  leader in a plane crash triggered massive violence. The Tutsi-led Rwandan  Patriotic Front (RPF) took over the country by force after the massacre of  almost one million Tutsi and Tutsi sympathizers by the Hutu. Two million</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1658 I Ryan &#x25BA; Ryukyu Islands</p><p>refugees, mostly Hutu, fled to neighboring Congo (Kinshasa) after the  RPF�s victory.

Native</p><p>to South Asia, today it is grown extensively in Europe, Asia, and North  America. It is planted mainly where climate and soil are relatively  unfavourable for other cereals and as a winter crop where temperatures  are too cold for winter wheat. Rye thrives at high altitudes and is the most  winter-hardy of all small grains. It is high in carbohydrates and provides  small quantities of protein, potassium, and B vitamins. Only rye and wheat  have the necessary qualities to make a loaf of bread, but rye lacks the  elasticity of wheat and thus is frequently blended with wheat flour. The  tough fibrous straw of rye is used for animal bedding, thatching, mat�  tresses, hats, and paper. Rye may be grown as a green manure crop.</p><p>Rye House Plot (1683) In English history, an alleged Whig conspiracy  to assassinate Charles II because of his pro-Catholic policies. The plot drew  its name from Rye House at Hoddeston, Hertfordshire, near the road  where Charles was supposed to be killed as he traveled from a horse meet.  The king�s unexpected early departure supposedly foiled the plot, which  was later revealed by an informer. The facts remained cloudy, but the main  plotters included the duke of Monmouth, William, Lord Russell, Algernon  Sidney (1622-1683), and Sir Thomas Armstrong. The last three were  tried, convicted of treason, and beheaded.</p><p>Ryerson Polytechnic University Privately endowed institution of  higher learning in Toronto, Ontario, Canada.

Active in Bolshevik revolutionary activities from age 18, he became a  party leader and, after Vladimir Lenin�s death, chairman of the Council of  People�s Commissars (1924-29). A strong supporter of the New Economic  Policy, he was joined by Joseph Stalin to defeat the economic radicals (and  Stalin�s rivals) Leon Trotsky, Grigory Zinovyev, and Lev Kamenev. When  Stalin then adopted his rivals� radical ideas, Rykov was stripped of his  posts and forced to recant his �Right Opposition� views (1929). In 1936  he was implicated in fabricated conspiracies, tried in Stalin�s purge trials,  and executed for treason.</p><p>Ryle, Gilbert (b. Aug. 19, 1900, Brighton, Sussex, Eng.�d. Oct. 6,  1976, Whitby, North Yorkshire) British philosopher, leading figure in the  �ordinary language,� or �Oxford� school of analytic philosophy. He became  a lecturer in philosophy at Christ Church College in 1924. He was Wayn-  flete professor of metaphysical philosophy at Oxford from 1945 to 1968  and editor of Mind from 1948 to 1971. His major work, The Concept of  Mind (1949), rejects Cartesian dualism as the logically incoherent doctrine  of the �ghost in the machine� and argues for a �logical behaviourism�  according to which attributions of mental states need refer only to the  behaviour of bodies and not to any mysterious entity hidden inside them.  His other works include Philosophical Arguments (1945), Dilemmas  (1954), A Rational Animal (1962), Plato�s Progress (1966), and The  Thinking of Thoughts (1968).</p><p>Ryle, Sir Martin (b. Sept. 27, 1918, Brighton, Sussex, Eng.�d. Oct.  14, 1984, Cambridge, Cambridgeshire) British radio astronomer. After  receiving a Ph.D. in physics from the University of Oxford, he helped  design radar equipment during World War II. He was an early investiga�  tor of extraterrestrial radio signals. Ryle guided the Cambridge radio  astronomy group in the production of radio source catalogs. The Third  Cambridge Catalogue (1959) helped lead to the discovery of the first  quasar. To map distant radio sources, he developed a technique called  aperture synthesis, which provided tremendously increased resolving  power for radio telescopes and was used to locate the first pulsar. In 1974  he and Antony Hewish shared a Nobel Prize.</p><p>Rymer Vri-morV, Thomas (b. 1643?, near Northallerton, Yorkshire,  Eng.�d. Dec. 14, 1713, London) English critic. Though called to the bar  in 1673, Rymer almost immediately turned to literary criticism. He is known  for introducing into England the principles of French formalist Neoclas�  sical criticism. Among his works are The Tragedies of the Last Age (1678)  and A Short View of Tragedy (1693), both highly critical of modern drama  and favouring classical tragedy. His views were very influential until the  19th century. Appointed historiographer royal in 1692, he compiled most  of the Foedera, a collection of treaties entered into by England that is of  considerable value to the medievalist.</p><p>Rydan \,re-o-'an\ Temple Japanese Ryoan-ji \re-o-'an-je\ Japanese  Buddhist temple in Kyoto, famous for its abstract meditation garden (c.  1500). An area approximately 30 by 70 ft (10 by 20 m) is covered with  raked gravel and set with 15 stones divided into five unequal groups. The  pattern of the design may be interpreted as rocky islets in a sea, but the  garden�s appeal lies essentially in the charm of its relationships and the  arrangement of rocks such that all 15 are not visible from any single van�  tage point.</p><p>Ryukyu \re-'yu-,kyu\ Islands Island chain, extreme southern Japan. It  extends in an arc 700 mi (1,100 km) long from the southern Japanese  island of Kyushu to the northern tip of Taiwan island. The 55 islands and  islets have a total land area of 1,193 sq mi (3,090 sq km). In ancient times  it was an independent kingdom, but Chinese and Japanese sovereignty  were successively imposed on the archipelago from the 14th to the 19th  century. In 1879 the Ryukyus became an integral part of Japan. After  Japan�s defeat in World War II, the U.S. took control of the islands; it  returned them all by 1972. The U.S. maintains military bases on Okinawa.  The islands are primarily rural, and agriculture is the dominant occupa�  tion; tourism has grown in importance.</p><p>"Toilers of the Sea," oil on wood panel  by Ryder, before 1884; in the Metro�  politan Museum of Art, New York City</p><p>COURTESY OF THE METROPOLITAN MUSEUM OF ART, NEW  YORK, GEORGE A.

From 1931 it was headed by Ernst Rohm, and by 1932  it had grown to a force of more than 400,000. Rohm wanted to merge the  regular army with the SA under his leadership, but Hitler had become  wary of the organization�s growing power.

It passed to Prussia in 1815 and became the capital  of the Saar region in 1919. The present city was formed in 1909 by the  union of the former Saarbriicken with Burbach-Malstatt, Sankt Johann,  and Sankt Arnual. In 1959 it was made capital of Saarland.

Sept. 1, 1961, Ann Arbor, Mich., U.S.) Finnish-born U.S. architect. His  father, Eliel Saarinen (1873-1950), was the foremost Finnish architect of  his time; his major works include the Helsinki railway sta�  tion (1904-14) and�after immigrating to the U.S. in  1923�the buildings of the Cranbrook Foundation, Bloom�  field Hills, Mich. (1925-41). Eero joined his father�s prac�  tice after studying at Yale. His vast General Motors  Technical Center in Warren, Mich. (1948-56), was fol�  lowed in 1948 by his design for the Gateway Arch in St.  Louis, Mo. (completed 1965). In the Kresge Auditorium  and chapel at MIT (1955), Cambridge, Mass., he used a �hand�  kerchief� dome resting on three points for the auditorium and  a stark red-brick cylinder for the chapel. His TWA termi�  nal at Kennedy International Airport (1956-62), New  York City, employs two cantilevered concrete shells that  extend dramatically outward, suggesting wings. Like  many contemporary architects, Saarinen was challenged  by furniture design, especially the chair. He is remem�  bered in particular for a chair in molded plywood he  designed with Charles Eames; a womblike chair using a  glass-fibre shell upholstered in foam rubber and fabric; and a  series of pedestal-based chairs and tables that combined a sculptural  aluminum base with plastic shells for the chairs and disks of marble or  plastic for the table tops.</p><p>Saarland \'zar-,lant,\ English \'sar-,land\ or Saargebiet \'zar-g3-,bet\  State (pop., 2002 est.: 1,066,470), southwestern Germany.

The region was contested by France and Germany from the 17th  century until 1815, when France ceded most of it to Prussia by the Treaty  of Paris. When Alsace-Lorraine was added to the German Empire in 1871,  the Saar ceased to be a boundary state and developed rapidly as a coal�  mining and industrial area, producing iron and steel. French military  forces occupied it after World War II, but it was restored to West Ger�  many and became a state in 1957.</p><p>Saba Island (pop., 1994 est.: 1,180) of the Netherlands Antilles in the  Caribbean Sea.

In that year the Banu TJtub, a group of families of  the �Anizah tribe living in what is now Kuwait, appointed a member of  the Sabah family, Sabah ibn Jabir (r. c. 1752-64), to be their ruler. The  dynasty frequently depended politically or militarily on outsiders but  maintained its autonomy. Its dependence on the Ottoman Empire in the late  19th century was subsequently a cause for Iraq to claim hegemony over  Kuwait. It later enjoyed the patronage of the United Kingdom and, more  recently, the support of the U.S. Despite the existence of deliberative  institutions in modem Kuwait, the dynasty retains absolute power.</p><p>Sabbath Day of the week set aside for worship and observance of reli�  gious duties in Judaism and Christianity.

To achieve this objec�  tive, Israel allied itself with several Lebanese Christian groups, including  the Phalange party, who fought the Palestinians during the protracted  Lebanese civil war (1975-90). Following the U.S.-brokered evacuation of  Palestine Liberation Organization (PLO) fighters from Beirut, Israeli forces  under Defense Minister Ariel Sharon allowed Phalange militiamen into  the camps, ostensibly to root out further PLO fighters. Estimates of the  number of women, children, and elderly who were killed over the next  several days ranged from 800 to several thousand. Although no militia�  men were ever prosecuted for their participation, Sharon�who an Israeli  commission of inquiry later found indirectly responsible through  negligence�was condemned in Arab popular opinion as the culprit of the  massacre.</p><p>Sabratha Vsa-bro-thoV or Sabrata Ancient city, Roman Africa.

His two altarpieces in the church of Santa  Maria della Concezione (1631-38) are distinguished by their Classicism.  Other notable works include eight canvases in the cupola of the Baptis�  tery of St. John in Rome (1639^-5). He was a skilled draftsman and the  leading exponent of the Classical tradition in 17th-century Roman paint�  ing.</p><p>Sacco-Vanzetti case Murder trial in Massachusetts (1920-27). After  the robbery and murder of a paymaster and a guard at a shoe factory  (1920), police arrested the Italian immigrant anarchists Nicola Sacco  (1891-1927), a shoemaker, and Bartolomeo Vanzetti (1888-1927), a fish  peddler. They were tried and found guilty. Radicals and socialists pro�  tested the men�s innocence, and many others felt they had been convicted  for their anarchist beliefs. In 1925 a convicted murderer confessed to par�  ticipating in the crime, but attempts to obtain a retrial failed and Sacco  and Vanzetti were sentenced to death in 1927. Protest meetings were held  throughout the U.S. Gov. Alvin Fuller appointed an advisory panel, which  agreed with his refusal to grant clemency, and the men were executed.  They became martyrs to radicals� belief that the legal system was biased.  Though opinion remained divided on the men�s guilt, most agreed that a  retrial was warranted. In 1977 Massachusetts governor Michael Dukakis  issued a proclamation stating that Sacco and Vanzetti had not been treated  justly and that no stigma should be associated with their names.</p><p>Sachs \'zaks,\ English Vsaks\, Curt (b.

He immigrated to the U.S. in 1960 to study neu�  rology at the University of California, and in 1965 he joined the faculty  at New York�s Albert Einstein College of Medicine. Many of his books  relate case histories of neurologically damaged people. His empathy with  those afflicted with strange conditions, including Tourette syndrome, amne�  sia, and autism, has been the hallmark of his writings. His book Awaken�  ings (1973), about the long-term effects of sleeping sickness, was filmed in  1990; other books include The Man Who Mistook His Wife for a Hat  (1986) and An Anthropologist on Mars (1995).</p><p>Sackville, Thomas, 1st earl of Dorset (b. 1536, Buckhurst, Sus�  sex, Eng.�d.

He was a member of the  Privy Council (1585) and conveyed the death sentence to Mary, Queen of  Scots, in 1586. He later served on diplomatic missions to The Hague and  served as lord high treasurer (1599-1608). He was also noted as the coau�  thor of The Tragedie of Gorboduc (1561), the earliest English drama in  blank verse, and for his �Induction,� the most famous part of the verse  collection A Myrrour for Magistrates (1563).</p><p>Sackville-West, Vita orig.

The daughter of a baron, she married the  diplomat and author Harold Nicolson (1886-1968) in 1913; her journal  was the basis of Portrait of a Marriage (1973) by their son Nigel, which  described a happy marriage in which both partners were principally homo�  sexual. Her gift for evoking the beauty of the Kentish countryside was  evident in her long poem The Land (1926). Her best-known novels are  The Edwardians (1930) and All Passion Spent (1931). She also wrote  biographies and gardening books. She was the inspiration for the title  character in her friend Virginia Woolf�s novel Orlando.</p><p>sacrament Religious action or symbol in which spiritual power is  believed to be transmitted through material elements or the performance  of ritual. The concept is ancient; prehistoric people believed that they</p><p>could advantageously influence events in the natural world, such as  weather patterns, through the performance of ritual. The word sacramen-  tum was used in Roman law and later became an oath of allegiance sol�  diers swore in a sacred place. The sacrament is primarily associated with  Christianity, and Christian theologians as early as St. Augustine focused on  the proper definition of sacrament. Among Christians, sacraments are said  to derive from practices instituted by Jesus, such as baptism, the washing  of the feet, and the casting out of demons. There are seven sacraments of  Roman Catholicism, as codified by St. Thomas Aquinas and promulgated by  the Council of Trent: baptism, confirmation, the Eucharist, penance, anoint�  ing of the sick, ordination, and matrimony. The Eastern Orthodox church  generally accepts seven sacraments, even though no council accepted by  the Orthodox church ever defined the number of sacraments. In most  Protestant churches, however, only baptism and the Lord�s Supper are  recognized as sacraments, as the understanding of sacrament differs from  that of the Roman Catholic church.

First settled in 1839 as New Helvetia by John Sutter, it became  an important trading centre during the gold rush. The present city was laid  out in 1848 and named for the river. It became the state capital in 1854  and prospered as a transportation and agricultural centre. It was the ter�  minus of the first California railroad in 1856 and the western terminus of  the Pony Express in 1860. A ship canal completed in 1963 made the city a  deepwater port. The city�s main industries, in addition to government ser�  vices, include food processing, printing, and aerospace products. It is the  site of several institutions of higher learning.</p><p>Sacramento River River, northern California, U.S. Rising near Mount  Shasta, it flows 382 mi (615 km) southwest between the Cascade and  Sierra Nevada ranges, through the northern Central Valley. It forms a  common delta with the San Joaquin River before entering the northern arm  of San Francisco Bay. California�s largest river, it is navigable for 180 mi  (290 km) and accommodates oceangoing vessels as far as Sacramento.  Scene of the gold rush of 1849, the river flows through one of the world�s  richest agricultural regions.</p><p>sacrifice Act of offering objects to a divinity, thereby making them holy.  The motivation for sacrifice is to perpetuate, intensify, or reestablish a  connection between the human and the divine. It is often intended to gain  the favour of the god or to placate divine wrath. The term has come to  be applied specifically to blood sacrifice, which entails the death or  destruction of the thing sacrificed (see human sacrifice). The sacrifice of  fruits, flowers, or crops (bloodless sacrifice) is more often referred to as  an offering.</p><p>sacrifice, human See human sacrifice</p><p>Sadat \so-'dat\, (Muhammad) Anwar el- (b. Dec. 25, 1918, Mit  Abu al-Kum, Egypt�d. Oct. 6, 1981, Cairo) President of Egypt (1970-  81). A graduate of the Cairo Military Academy, he joined Gamal Abdel  Nasser�s coup that deposed the monarchy in 1950 and later served as vice  president (1964-66, 1969-70). He became president when Nasser died in  1970. He led Egypt during the Yom Kippur War (1973) against Israel. A  military loss, the war was a political success for Sadat, bolstering his  popularity through the Arab world. At home, he reversed many of Nass�  er�s socialist policies and attempted to garner the support of the country�s  Islamists. In 1977 he went to Jerusalem to offer peace to Israel, and in  1979 he concluded a peace treaty, the Camp David Accords, with Israeli  prime minister Menachem Begin. The two men shared the 1978 Nobel Prize  for Peace. His popularity in the Arab world plummeted, and domestic  support for his treaty with the Jewish state�especially among Islamists�  evaporated. He was killed by a group of Muslim extremists led by Kha-  lid al-lsiAMBUU and associated with the Islamic Jihad Group. See also Arab-  Israeli Wars; Hosni Mubarak.</p><p>Saddam Hussein (b.

Following participation  in a failed attempt to assassinate Iraqi Pres. c Abd al-Karim Qasim in 1959,  Saddam fled to Cairo, where he briefly attended law school. He returned  to Iraq when the Ba'thists gained power in 1963. Jailed when the Ba'thists  were overthrown, he escaped and helped reinstall the party to power in  1968. He led the nationalization of the oil industry in 1972. He took over  the presidency with the aims of replacing Egypt as leader of the Arab  world and of gaining hegemony over the Persian Gulf, and he launched  wars against Iran (Iran-Iraq War, 1980-90) and Kuwait (First Persian Gulf</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1662 I saddle &#x25BA; saffron</p><p>War, 1990-91), both of which he lost. He instituted a brutal dictatorship  and directed intensive campaigns against minorities within Iraq, particu�  larly the Kurds. U.S. fears regarding his development of weapons of mass  destruction led to Western sanctions against Iraq. Sanctions were followed  by an Anglo-American invasion in 2003 (Second Persian Gulf War) that  drove him from power. After several months in hiding, he was captured  by U.S. forces.

The  leather saddle was developed between the 3rd century bc and the 1st cen�  tury ad, probably by peoples of the Asian steppes, where the stirrup and  the horse collar also originated. The saddle greatly improved a rider�s  ability to control a moving horse, especially in combat. Improvements  made in medieval Europe were related to feudal battles among knights.  Modern saddles are mainly divided into two types: the light, flat English  or Hungarian style used for sport and recreation, and the sturdy Western  style used originally for cattle roping and now also for recreation.</p><p>Sadducee \'sa-jo-,se\ Member of a Jewish priestly sect that flourished  for about two centuries, until the destruction (ad 70) of the Second Temple  of Jerusalem. Sadducees were generally wealthier, more conservative, and  better connected politically than their rivals, the Pharisees. They believed  in strict interpretation of the Torah and thus rejected such ideas as immor�  tality of the soul, bodily resurrection after death, and the existence of  angels. They viewed Jesus' ministry with mistrust and are believed to have  played some part in his death. Their wealth and complicity with Roman  rulers made them unpopular with the common people.</p><p>Sade Vsad\, Marquis de orig. Donatien-Alphonse-Francois,  count de Sade (b. June 2, 1740, Paris, France�d. Dec. 2, 1814,  Charenton, near Paris) French novelist and philosopher. After abandon�  ing a military career at the end of the Seven Years� War, he married and  became involved in a life of debauchery and outrageous scandal with  prostitutes and with local young people he abducted, for which he was  repeatedly imprisoned, once narrowly escaping execution. Despite his  noble birth, he supported the French Revolution, which he saw as repre�  senting political liberation on a level parallel to the sexual liberation he  himself represented. He was twice sent to the insane asylum at Charen�  ton (1789-90, 1801-14), where he would eventually die. He overcame  boredom and anger in prison and the asylum by writing sexually graphic  novels and plays. The 120 Days of Sodom (written 1785) was a tale of  four libertines who kidnap victims for a nonstop orgy of perversion. In  his most famous novel, Justine (1791), the heroine suffers because she  fails to perceive that there is no moral God and that desire is the only  reality. His other works include Philosophy in the Bedroom (1793) and  Crimes of Passion (1800). His reputation and writings gave rise to the  term sadism.</p><p>sadhu and swami In India, a religious ascetic or holy person. Sadhus  are typically wandering ascetics who subsist on alms. They may follow  the tenets of a particular belief system, such as Hinduism or Jainism, but are  more typically regarded as saintly in their own right. The term swami  refers to a sadhu ordained in a specific order and is associated particu�  larly with Vedanta. Sadhus and swamis may live either in communities  or in solitude; they typically possess little, eschew conventional and mod�  ern dress, and have shaven heads or matted, unkempt hair.</p><p>sadism Ysa-.di-zom, �sa-.di-zonA Psychosexual disorder in which sexual  urges are gratified by inflicting pain on another person. The term was  coined in reference to the marquis de Sade, who chronicled his own such  practices.

In 1960 he moved to Lebanon, where he became involved in  social work among the country�s largely disfranchised Shl'ite community.  In 1968-69 he formed the Higher Shl'ite Islamic Council to promote the  community�s interests, and in 1975 he formed a militia, Amal, to defend the  Shl'ite community in the Lebanese Civil War. He and a small entourage dis�  appeared while on an official trip in Libya.

Son of  an engraver, he became a friend of the architect Jacob van Campen (1595�  1657), which may have influenced him to specialize in architectural paint�  ing. A pioneer of the �church portrait,� he was the first Dutch artist to  abandon the Mannerist tradition of fanciful invention in architectural  painting in favour of a new realism in rendering specific buildings. His  paintings of church interiors show a scrupulous precision and convey a  majestic spaciousness and serenity.</p><p>Safaqis See Sfax</p><p>Safavid \sa-�fa-v3d\ dynasty (1502-1736) Persian dynasty. It was  founded by Isma'il I, who, by converting his people from Sunnite to Shl'ite  Islam and adopting the trappings of Persian monarchy, planted the seeds  of a unique national and religious identity. He captured Tabriz from the  Ak Koyunlu and became shah of Azerbaijan (1501) and Persia (1502).  'Abbas I (r. 1588-1629) brought the dynasty to its peak; his capital,  Esfahan, was the centre of Safavid architectural achievement. The dynasty  declined in the century following his reign, pressed by the Ottoman Empire  and the Mughal dynasty, and fell when a weak shah, Tahmasp II, was  deposed by his general, Nadir Shah.</p><p>Safdie Vsaf-de\, Moshe (b. July 14, 1938, Haifa, Palestine) Israeli-  Canadian architect. Educated at McGill University School of Architec�  ture, Montreal, he began his career in the offices of Louis Kahn. His Habitat  �67 was a bold experiment in prefabricated housing using modular units;  the design was for a prefabricated concrete housing complex of individual  apartment units stacked irregularly along a zigzagged framework that was  evocative of an Italian hill town or a pueblo. This aroused intense inter�  national interest but failed to catch on as a low-cost housing construction  method. Later works include Yeshivat Porat Joseph Rabbinical College in  Jerusalem (1971-79) and Coldspring New Town near Baltimore (1971).  He served as director of urban design at Harvard University, 1978-84.</p><p>safety Activities that seek to minimize or to eliminate hazardous con�  ditions that can cause bodily injury.

Once thought  to be orally transmitted history that had finally been written down, sagas  are now usually regarded as reconstructions of the past, imaginative in  varying degrees and created according to aesthetic principles. Important  ideals in sagas are heroism and loyalty; revenge often plays a part. Action  is preferred to reflection, and description of the inner motives and point  of view of protagonists is minimized. Subdivisions of the genre include  kings� sagas, recounting the lives of Scandinavian rulers; legendary sagas,  treating themes from myth and legend; and Icelanders' sagas.

He worked as an errand  boy, studying arithmetic and book�  keeping in his spare time, and in 1839 he started a wholesale grocery  business, which earned him enough money to start a Hudson River ship�  ping trade. He served in Congress (1853-57). Sage invested successfully  in the La Crosse Railroad in Wisconsin, and he eventually acquired an</p><p>interest in more than 40 railroads, serving as director or president of 20.  He helped organize the Atlantic &amp; Pacific Telegraph Co. In 1872 he origi�  nated stock-market puts and calls (options to buy or sell a set amount of  stock at a set price and within a given time limit), but he stopped dealing  in them after losing $7 million in the panic of 1884.

Questioning the traditional belief that chromosomal genes are the only  apparatus for transmitting genetic information to a cell, she discovered  (1953) in the alga Chlamydomonas the existence of a second genetic  transmitting system, a gene not located on the alga�s chromosomes that  controls the cell�s sensitivity to the antibiotic streptomycin, and she  observed that both male and female Chlamydomonas can transmit the  nonchromosomal gene.</p><p>Sagittarius \,sa-j9-'ter-e-3s\ Latin "Archer" In astronomy, the con�  stellation lying between Capricorn and Scorpio; in astrology, the ninth  sign of the ZODIAC, governing approximately the period November  22-December 21. Its symbol is either a centaur shooting a bow and arrow  or an arrow drawn across a bow. The association of this constellation with  a mounted archer originated in Babylonia as early as the 11th century bc.</p><p>Sagittarius A Strongest source of cosmic radio waves, lying in the  direction of the constellation Sagittarius. Discovered by Karl Jansky in  1932, it has been identified as the nucleus of the Milky Way Galaxy. The  region is relatively small and constitutes an intense source of infrared  radiation thought to be emitted partly by stars and partly by dust around  them. Within the region is a much smaller radio source, Sagittarius (Sgr)  A<emphasis>, which appears to mark the centre of the Galaxy. Observations indi�  cate that the galactic nucleus contains a black hole with a mass of one  million to several million times that of the Sun; they also provide a strong  case that Sgr A</emphasis> is the black hole. The activity at the Galaxy�s centre  resembles that of an active galactic nucleus but on a much smaller scale.</p><p>sago Vsa-go\ Food starch prepared from carbohydrate material stored in  the trunks of several palms, chiefly Metroxylon rumphii and M. sagu, sago  palms native to Indonesia. Composed of 88% carbohydrate, sago is a basic  food of the South Pacific, where it is used in meal form to prepare soups,  cakes, and puddings. Elsewhere its use in cookery is mainly as a pudding  and sauce thickener. In industry it is used as a textile stiffener. The thick  trunk grows to 30 ft (9 m) tall in low marshy areas. At 15 years the core  of the mature trunk is engorged with starchy material. If allowed to form  and ripen, the fruit absorbs the starch, leaving the stem hollow and dying.  Cultivated plants thus are cut down when the flower spike appears, and  the starchy pith is extracted from the stems.</p><p>saguaro \s3-'war-3, s3-'gwar-o\ Large, candelabra-shaped, branched  CACTUS {Cereus giganteus, or Carnegiea gigantea ) native to Mexico, Ari�  zona, and California. Slow-growing at first, mature saguaros may even�  tually reach 50 ft (15 m) in height. They bloom for the first time when  50-75 years old. They may die at 150-200 years (at a weight of up to 10  tons, or 9,000 kg), most commonly by being uprooted by wind or wash�  outs.

Extending from Senegal eastward to The Sudan, it forms a nar�  row transitional band between the arid Sahara to the north and the humid  savannas to the south. Beginning in the late 20th century, it was subjected  to increased desertification and soil erosion caused by natural climate  changes as well as overgrazing and overfarming. The countries of the zone  suffered a devastating drought and famine in the early 1970s, and by 1973  sections of the Sahara had advanced southward as much as 60 mi (100  km). Severe drought and famine again struck the region in 1983-85.

His work  dominated the Mewar school of Rajasthani painting. Though he was a  Muslim, Sahibdin was fully at ease with Hindu themes. He produced  abstract compositions that are full of brilliant colour and endowed with  religious fervour. Among the important surviving examples of his paint�  ings are a ragamala (musical modes) series (1628); a series on the  Bhagavata-Purana, a scriptural text (1648); and the sixth book ( Yuddha-  kanda ) of the Hindu epic the Ramayana (1652).</p><p>Saicho \ , s!-,cho\ or Dengyo Daishi (b. 767, Omi province, Japan�d.  822, Hiei-zan) Monk who established the Tendai (Chinese Tiantai) sect of  Buddhism in Japan.

Said  was educated in Western schools in Jerusalem and Cairo before moving  to the United States to attend Princeton and Harvard universities. He  taught at Columbia University beginning in 1963. In Orientalism (1978),  his best-known work, he examines Western stereotypes of the Islamic  world and argues that Orientalist scholarship is based on Western impe�  rialism. An outspoken proponent of Palestinian issues, he wrote on the  Middle East in such works as The Question of Palestine (1979) and The  Politics of Dispossession (1994). His more general concern was the com�  plex interaction of literature and politics, which he treated in Beginnings  (1975), The World, the Text, and the Critic (1983), and Culture and Impe�  rialism (1993).

A samurai from  the domain of Satsuma, Saigo joined Okubo Toshimichi and Kido Takayoshi in  working to overthrow the Tokugawa shogunate (military government) and  restore rule by the emperor. He commanded the troops that seized control  of the imperial palace from the shogunate, and went on to lead a campaign  against the shogunate�s supporters. After the Meiji Restoration (1868), he  was given command of the new Imperial Guard. In 1873 he supported a war  with Korea; when this plan was cancelled, he resigned from government.  He opened a military school in his native Kagoshima that drew to it disaf�  fected former samurai (class distinctions had been abolished in 1871). In  1877 some of his disciples attacked a government arsenal, and he found  himself the unwilling head of a rebellion. It lasted for six months and  resulted in some 12,000 dead on both sides, including Saigo himself.

In the New Testament, St. Paul used the term to mean  a member of the Christian community, but the term more commonly refers  to those noted for their holiness and venerated during their lifetimes or  after death. In Roman Catholicism and Eastern Orthodoxy, saints are pub�  licly recognized by the church and are considered intercessors with God  for the living. They are honoured on special feast days, and their remains  and personal effects are venerated as relics. Often Christian saints per�  form miracles in their lifetime, or miracles occur in their names after their  death. In Islam, xvali (�friend of God�) is often translated as saint; in Bud�  dhism, arhats and bodhisattvas are roughly equivalent to saints. Hindu  sadhus are somewhat similar.

As part of the ongo�  ing Wars of Religion, Catherine de Medicis agreed to a plot by the Guise  family (see house of Guise) to assassinate the Huguenot Gaspard II de  Coligny. When he was only wounded, Catherine feared discovery of her  complicity and secretly urged faithful nobles to murder all the Huguenot  leaders, who were in Paris for the wedding of the future Henry IV. The  massacre began on August 24 and spread rapidly; after the leaders had  been murdered, Huguenot homes and shops were pillaged and their occu�  pants murdered and thrown into the Seine. Even after the royal order on  August 25 to stop the killing, it continued and spread to Rouen, Lyon,  Bourges, Orleans, and Bordeaux. By October, about 3,000 Huguenots had  been murdered in Paris and probably tens of thousands more in the prov�  inces.</p><p>Saint Basil the Blessed or Pokrovsky \po- l krof-ske\ Cathedral  Church constructed at the southern end of Red Square in Moscow (1554-  60) by Ivan IV as a votive offering for his military victories over the Tatars.

The family is sometimes considered part of the family Guttiferae. The  majority of species (about 300) belong to the genus Hypericum. Their  leaves are opposite or whorled, dotted with glands, and usually have  smooth margins. Several species are cultivated in temperate regions for  their handsome flowers. H. perforatum, a showy golden flower grown in  both the Old and New Worlds whose buds contain a red oil, has long been  credited with magical and medicinal powers; today it is being widely used  and studied for its possible efficacy against depression.</p><p>Saint-Just \sa n -'zhmst\, Louis (-Antoine-Leon) de (b.

First settled in 1838, it was known as Pig�s Eye until 1841, when a log  chapel dedicated to St. Paul was built there. It became the capital of the  Minnesota Territory in 1849 and of the state in 1858. It was important in  the development of the upper Midwest because of its location on the Mis�  sissippi and its rail links, which promoted its livestock market. It is a major  transportation, commercial, and industrial centre with diversified manu�  factures, including automobiles, electronic equipment, and food products.

The present building is a domed church of great openness designed  in a restrained style that combines elements of Neoclassical, Gothic, and  Baroque architecture. It was designed by Christopher Wren and con�  structed (1675-1710) of Portland stone. The building replaced Old St.  Paul�s, destroyed in the Great Fire of 1666. The interior is characterized  by ironwork and woodcarving by master crafts workers. The majestic  dome, set on a colonnaded drum, rises 365 ft (111 m). The superbly  detailed cathedral that Wren built bears only a slight resemblance to the  Classical-Gothic design that had been accepted; why this is so remains a  mystery.</p><p>Saint Peter's Basilica Present church of St. Peter�s in Rome, begun  by Pope Julius II in 1506 and completed in 1615. It is the church of the  popes and one of the world�s largest churches. It was built to replace Old  St. Peter�s, erected by Constantine over Peter�s traditional burial place.  According to the original plan of Donato Bramante, it was to take the form  of a Greek cross around a central dome. Successive architects, including  Raphael, drew fresh plans after Bramante�s death, modifying the original  Greek-cross plan to a Latin cross. Antonio da Sangallo the Younger  returned to Bramante�s symmetrical plan. Michelangelo, who followed  Sangallo, nearly completed the drum for the massive dome before his  death. Pope Paul V (r. 1605-21) then insisted on a longitudinal plan for  liturgical reasons and adopted the plan of Carlo Mademo (1556-1629),  which extended the nave to the east. Gian Lorenzo Bernini added the ellip�  tical piazza, lined by colonnades, that serves as the approach to the  basilica. The interior is filled with Renaissance and Baroque masteipieces,  including Michelangelo�s Pieta, Bernini�s baldachin, a statue of St. Longi�  nus, the tomb of Urban VIII, and a bronze throne of St. Peter.</p><p>Saint Petersburg Russian Sankt-Peterburg Vsankt-,p y 3-  t y or-'burk\ formerly (1914-24) Petrograd or (1924-91) Leningrad  City (pop., 2002: 4,669,400) and port, northwestern Russia. Located on  the delta of the Neva River where it enters the Gulf of Finland, it is Rus�  sia�s second largest city after Moscow. Founded by Peter I (the Great) in  1703, it was the capital of the Russian Empire from 1712 to 1917. It was  the scene of the Decembrist revolt in 1825 and the Bloody Sunday attack  on workers in the Russian Revolution of 1905. The original centre of the  Bolshevik revolution (see Russian Revolution of 1917), it lost its capital  status to Moscow in 1918. In World War II it underwent a siege by Ger�  man forces (September 1941-January 1944), during which hundreds of  thousands of people died (see Siege of Leningrad). From 1990 a reform�  ist city council and mayor helped swing the country from the control of  the Communist Party of the Soviet Union. St. Petersburg is a cultural, edu�  cational, and industrial centre and Russia�s largest seaport. Industries  include engineering, printing, manufacturing, and shipbuilding. One of  Europe�s most beautiful cities, it is strewn with canals and several hun�  dred bridges; its many palaces, cathedrals, museums (including the Her�  mitage), and historical monuments were designated a UNESCO World  Heritage site in 1990.</p><p>Saint Petersburg City (pop., 2000: 248,232), west-central Florida,  U.S. It lies near the tip of Pinellas Peninsula, adjacent to Tampa Bay.

St.-Pierre, with an area of 10 sq mi (26  sq km), is the administrative and commercial centre; almost 90% of the  population live there. First settled by seafarers from western France early  in the 17th century, the islands changed hands several times between  France and Britain until an 1814 treaty made French possession final.  They were classified as a French territory in 1946, a department in 1976,  and a territorial collectivity in 1985.

To promote  new music by French composers, he founded the Societe Nationale de  Musique in 1871. His compositions are often brilliant in their effects but  not always profound. Of his 13 operas, Samson et Dalila (1877) had the  greatest success. He wrote piano, cello, and violin concertos and three  symphonies (including the � Organ � Symphony, 1886); his tone poem  Danse macabre (1874) and the suite Carnival of the Animals (1886) are  widely known.</p><p>Saint-Simon \sa n -se-'mo n \, (Claude-) Henri (de Rouvroy,  comte) de (b.

The  capital, Charlotte Amalie, has a well-sheltered harbour. Sighted in 1493 by  Christopher Columbus, St. Thomas was colonized first by the Dutch (1657)  and then by the Danish (1666). After 1673, when slavery was introduced,  the island became one of the chief Caribbean sugar producers and a major  slaving centre. Falling sugar prices after 1820 and the abolition of slavery  in 1848 led to a decrease in profits. The U.S. bought St. Thomas for use as  a naval base in 1917. The chief industry is tourism.</p><p>Saint Vincent, Cape Cape, Portugal. Located at the southwesternmost  point of Portugal, the cape was known to the Greeks and Romans as  Promontorium Sacrum (�Sacred Point�) because of a shrine there. Pasto-  ralism and fishing are the economic mainstays of the region. Near Sagres,  the main settlement, was the town of Vila do Infante, where c. 1420 Prince  Henry the Navigator established a naval observatory and school for navi�  gators. Many naval battles have taken place off the cape.</p><p>Saint Vincent, Gulf Triangular inlet of the Indian Ocean, southeast�  ern Australia.

Located in the  delta on the Canopic, or Rosetta, branch of the Nile River, it was from  prehistoric times the site of the chief shrine of Neith, goddess of war and  the loom. It became the capital of Egypt under Psamtik I (r. 664-609 bc).</p><p>His successors of the 26th dynasty also had their capital there. Enriched  by trade from the Mediterranean region and Africa, the Saite kings built  fine temples, palaces, and tombs. Inscribed stones found on the site and  in nearby villages are all that remain of the once-great city.</p><p>Saivism See Shaivism</p><p>saivo Vsl-,vu\ One of the Sami regions of the dead, where the deceased  lead happy lives with their families and ancestors, acting in every way as  they did on earth. In Norway the saivo world was thought to exist in the  mountains, whereas in Finland it was usually believed to be under spe�  cial double-bottomed lakes. These localities were regarded as sacred and  as sources of power that could be used by the shaman, or noaide. When  the noaide wished to go into a trance, he would ask his guardian spirits  from the saivo to aid him.</p><p>Sakakura \,sa-ka-'ku-ra\ Junzo (b. May 29, 1904, Gifu prefecture,  Japan�d. Sept. 1, 1969, Tokyo) Japanese architect. He was one of the  first to combine 20th-century European architecture with traditional Japa�  nese elements. His first outstanding East-West blend was the Japanese  pavilion at the 1937 World Exposition in Paris. He worked in the Paris  office of Le Corbusier (1931-36) and was known as Le Corbusier�s lead�  ing advocate in Japan. His major works include the Museum of Modern  Art in Kamakura (1951) and Shinjuku Station Square and Odakyu Depart�  ment Store in Tokyo (1964-67).</p><p>sake Vsa-ke\ Japanese alcoholic beverage made from fermented rice. It  dates to at least the 3rd century ad. Sake is light in colour and noncar-  bonated, with a sweet flavour; its alcohol content is about 18% by vol�  ume. Often mistakenly called a wine, sake is closer in its method of  manufacture to beer. Steamed rice is combined with a mold that converts  the rice starch to fermentable sugars; the mix is kneaded into a paste, twice  fermented (with fresh rice and water added), filtered, and bottled. In Japan,  where it is the national beverage and the traditional drink of the Shinto  gods, sake is warmed in a small earthenware or porcelain vessel before  being blessed and served in small porcelain cups.</p><p>Sakha or Yakut Siberian people who speak a Turkic language. Most  were formerly seminomadic, raising cattle and horses. They lived in win�  ter settlements of earth-covered log huts and summer camps of conical  birch-bark tents near pasturage and sources of hay for winter fodder.  Through assimilation, many southern Sakha turned to farming while  northern Sakha adopted reindeer breeding from the Evenk. The Sakha  were noted for their ironwork (supernatural power was attributed to black�  smiths) and also made pottery; traditional arts such as ivory and wood  carving are still practiced. Filmmaking has become popular more recently.  The Sakha number about 380,000. See also Siberian peoples.</p><p>Sakhalin \,sa-ka-'len\ Island Island, extreme eastern Russia. Together  with the Kuril Islands, it forms an administrative region of Russia. It is 589  mi (948 km) long and a maximum of 100 mi (160 km) wide; it covers  29,500 sq mi (76,400 sq km). Sakhalin was first settled by Russians in  1853, and it came under Russian control in 1875 when Japan ceded it in  exchange for the Kuril Islands. Japan held the southern part from 1905  to 1945, then ceded it and the Kurils to the U.S.S.R. The economy is  dominated by fishing, lumbering, coal mining, and the extraction of oil  and natural gas in the north.</p><p>Sakharov \'sa-k3-,r6f\, Andrey (Dmitriyevich) (b. May 21, 1921,  Moscow, Russia�d. Dec. 14, 1989, Moscow) Russian nuclear physicist  and human rights advocate. He worked with I.Y. Tamm (1895-1971) to  develop the Soviet Union�s first hydrogen bomb, but in 1961 he opposed  Nikita Khrushchev�s plan to test a 100-megaton hydrogen bomb in the  atmosphere. In 1968 he published in the West �Progress, Coexistence, and  Intellectual Freedom,� which called for nuclear arms reduction and criti�  cized Soviet repression of dissidents. He and his wife, Yelena G. Bonner,  continued to advocate civil liberties and reform in the Soviet Union. In  1975 Sakharov received the Nobel Prize for Peace but was forbidden to  travel to Oslo to receive it. In 1980 he was exiled to the closed city Gorky  (now Nizhny Novgorod); his wife was exiled there in 1984. They were  released in 1986 and returned to Moscow. Elected to the Congress of Peo�  ple�s Deputies in April 1989, Sakharov had his honours restored and saw  many of the causes for which he had fought and suffered become official  policy under Mikhail Gorbachev.</p><p>Saki \'sa-ke\ orig.

March 4, 1193, Damascus, Syria) Kur�  dish sultan of Egypt, Syria, Yemen, and Palestine and founder of the  AyyObid dynasty. Though as a youth he preferred religious to military stud�  ies, he began his military career under his uncle, a military commander  of the Zangid dynasty. On his uncle�s death, Saladin became vizier of the  Fajimid dynasty of Egypt. In 1171 he abolished the Shl'ite Fatimid caliph�  ate and announced a return to Sunnite Islam in Egypt. From 1174, as sul�  tan of Egypt and Syria, he succeeded in uniting Egypt, Syria, northern  Mesopotamia, and Palestine. His reputation as a generous and virtuous  but firm ruler rekindled Muslim resistance to the Crusades. In 1187, turn�  ing his full strength against the Latin Crusader states, he captured Jerus�  alem, which had been in Christian hands for 88 years. Whereas the  Christian conquest had been marked by slaughter, Saladin�s troops dem�  onstrated courteous and civilized behaviour. His victory deeply shocked  the West and led to the call for the Third Crusade (1189-92), which  matched him against Richard I (the Lionheart); their stalemate resulted in  a peace that gave the Crusaders only a small strip of land from Tyre to  Yafo (Jaffa). Many Muslims consider Saladin the paradigm of the pious  and virtuous ruler.</p><p>Salado \sa-Ta-tho\ River River, eastern Argentina. It flows through the  Pampas, generally southeast for about 400 mi (640 km) to the Atlantic  Ocean, where it empties southeast of Buenos Aires.

An important Iberian settlement, it was sacked  by Hannibal in 217 bc. It later became a Roman station. Captured by  Moors in the 8th century, it was reconquered by Christians from 1087 to  1102. It was occupied by the French in the Peninsular War (1808-14). It  is a cultural centre as well as the commercial centre of an agricultural  district. Its many landmarks include the 12th-century Romanesque cathe�  dral, the Gothic-style cathedral (begun 1513), and the University of Sala�  manca (founded 1218).</p><p>salamander Any member of about 400 species in 10 amphibian fami�  lies (order Caudata), commonly  found in fresh water and damp  woodlands, principally in temperate  regions of the Northern Hemisphere.</p><p>Salamanders are generally nocturnal,  short-bodied, 4-6 in. (10-15 cm)  long, and brightly coloured. They  have a tail, two pairs of limbs of  roughly the same size, moist, smooth  skin, teeth on the jaws and roof of the  mouth, and, usually, internal fertili�  zation. The largest species, the Chi�  nese giant salamander ( Andrias davidianus), is 5 ft (1.5 m) long.  Salamanders eat insects, worms, snails, and other small animals, includ�  ing members of their own species. See also hellbender; newt.</p><p>Salamis \'sa-l3-m9s\ Ancient city, Cyprus. Located on Cyprus�s east�  ern coast, it had an active trade with Phoenicia, Egypt, and Cilicia. Accord�  ing to tradition, it was founded by Teucer, a hero of the Trojan War. A</p><p>major Hellenic centre during the struggles between Greece and Persia, it  was the scene of a Greek naval victory in 449 bc; in 306 bc the Mace�  donian king Demetrius I (Poliorcetes) defeated Ptolemy I (Soter) of Egypt  near there. The city was visited later by SS Paul and Barnabas. It was  known as Constantia after the Byzantine emperor Constantius II rebuilt  it (ad 337-61). It was abandoned after its destruction by the Arabs in  647^18.</p><p>Salamis, Battle of (480 bc) Significant naval battle of the Persian  Wars, the first ever recorded. (Aeschylus served in the battle and wrote  The Persians , which is the earliest of his works to survive.) The Greek  fleet of some 370 triremes, under the command of Themistocles, lured the  Persian fleet of about 800 galleys into the narrow strait between the island  of Salamis and the Athenian port of Piraeus. There the highly maneuver-  able triremes sank about 300 Persian vessels while losing only about 40  of their own. As a result of this battle, Xerxes had to postpone his planned  land offensive, giving the Greek city-states time to unite against him.</p><p>Salan \sa-'la n \, Raoul (-Albin-Louis) (b. June 10, 1899, Roque-  courbe, France�d. July 3, 1984, Paris) French military officer who sought  to prevent Algerian independence. During a military career in which he  became the French army�s most decorated soldier, he served in France  during World War I (1914-18), French West Africa (1941-44), French  Indochina (1945-53), and Algeria (1956-62). Rebelling against Charles  de Gaulle�s decision to free Algeria, in 1961 he formed a right-wing  extremist group, the Secret Army Organization, which terrorized France  and Algeria. He was captured in 1962 and tried for treason.</p><p>Salazar V.sa-lo-'ziuA, Antonio de Oliveira (b. April 28, 1889, Vim-  ierio, Port.�d. July 27, 1970, Lisbon) Portuguese prime minister (1932�  68). A professor of economics, he was appointed by Pres. Antonio Oscar  de Fragoso Carmona as finance minister (1928) and later prime minister  (1932). His new constitution established the authoritarian New State, cur�  tailing political freedom and concentrating on economic recovery, and he  thenceforth ruled as a virtual dictator. Sympathetic to Francisco Franco  and the Axis Powers, he maintained Portugal�s neutrality in World War  II, and after the war he led Portugal into NATO. He greatly improved the  country�s transportation, utilities, and education systems. He fought to  preserve Portugal�s African colonies after the general decolonization.  Incapacitated by a stroke in 1968 after 36 years in power, he was not told  when he was replaced as prime minister.</p><p>Sale \sa-'la\ Arabic Sla \'sla\ City (pop., 1994: city, 504,420; Rabat-  Sale metro, area, 1,385,872), northwestern Morocco. Located at the mouth  of the Bou Regreg River, opposite Rabat, it was founded in the 10th cen�  tury and reached its peak as a merchant port. After 1627 Sale, with Rabat  as its vassal, became the corsair republic of Bou Regreg and the base for  the Sallee Corsairs, the most dreaded of the Barbary Coast pirates. The  two cities grew together until the Bou Regreg silted up and Sale port was  closed. It has many mosques and mausoleums; its greatest shrine is the  tomb of Sid! c Abd Allah ibn Hasan, the city�s patron saint.</p><p>Salem City (pop., 2000: 136,924), capital of Oregon, U.S. It lies along  the Willamette River, southwest of Portland. Founded in 1840, the town  prospered as migration increased over the Oregon Trail. It became the state  capital in 1859. It was an early river port whose growth was stimulated  by rail connections in the 1870s. It is a food-processing centre for a fruit�  growing and dairy area and has wood and light manufacturing industries.</p><p>Salem witch trials (May-October 1692) American colonial persecu�  tions for witchcraft. In the town of Salem, Massachusetts Bay Colony,  several young girls, stimulated by supernatural tales told by a West Indian  slave, claimed to be possessed by the devil and accused three women of  witchcraft. Under pressure, the accused women named others in false  confessions. Encouraged by the clergy, a special civil court was convened  with three judges, including Samuel Sewall, to conduct the trials. They  resulted in the conviction and hanging of 19 �witches� and the imprison�  ment of nearly 150 others. As public zeal abated, the trials were stopped  and then condemned. The colonial legislature later annulled the convic�  tions.</p><p>Salerno City (pop., 2001 prelim.: 144,078), southern Italy. Located on  the Gulf of Salerno, it was founded by the Romans in 197 bc on the site of  an earlier town. Part of a Lombard duchy from ad 646, it was the capital of  an independent Lombard principality from 839 to c. 1076. It was then con�  quered by the Norman Robert Guiscard and became his capital. It was later  incorporated into the Kingdom of Naples.

A sales tax  on the manufacture, purchase, sale, or consumption of a specific com�  modity is known as an excise tax. Though excise taxes have been used  since ancient times, the general sales tax is a comparatively recent inno�  vation. Sales taxes are ad valorem taxes, imposed �according to the value�  (i.e., monetary value) of the taxable commodity. They are classified  according to the levels of business activity at which they are imposed�  production, wholesale, or retail. They account for significant portions of  the revenue of most U.S. states and Canadian provinces. A variation of  the sales tax, the value-added tax, became popular in western European  countries and is widely used. Most sales taxes are borne by the consumer,  since even where they are levied on production or wholesale goods, part  or all of the cost is shifted to the consumer in the form of higher prices.  Because the retail sales tax is considered a regressive tax, essential goods  such as food, clothing, or drugs are sometimes exempted or taxed at a  lower level. See also income tax; progressive tax.</p><p>Salesbury \'salz-,ber-e\ A William (b. c. 1520, Cae Du, Llansannan,  Denbighshire, Wales�d. c. 1584, Llanrwst) Welsh lexicographer and  translator.

Feb. 8, 1944, Aimores, Braz.) Brazilian pho-  tojoumalist. He briefly pursued a career as an economist before switch�  ing his focus to photography in 1971. Over the next decade he  photographed stories such as the famine in Niger and the civil war in  Mozambique. In 1979 he joined the prestigious Magnum Photos coop�  erative for photojournalists, and two years later he gained prominence as  a result of his photograph of John Hinckley�s attempt to assassinate U.S.  Pres. Ronald Reagan. By the mid 1980s Salgado devoted himself almost  entirely to long-term projects that told a story through a series of images,  often focusing on the homeless and downtrodden. Among his critically  acclaimed books of photographs are Other Americas (1986), Workers  (1993), and Migrations: Humanity in Transition (2000).</p><p>salicylic \,sa-b-'si-lik\ acid White, crystalline solid organic compound  used chiefly to make aspirin and other pharmaceutical products, including  methyl salicylate (oil of wintergreen, for medicines and flavourings), phe�  nyl salicylate (for sunburn creams and pill coatings), and salicylanilide (a  cutaneous fungicide). Its molecular structure, with the formula  C 6 H 4 (OH)COOH, consists of a six-membered aromatic ring (see aromatic  compound) having a hydroxyl group (�OH) and a carboxyl group  (�COOH) bonded to adjacent carbon atoms; as such, it is both a phenol  and a carboxylic acid. It and certain derivatives occur naturally in some  plants, particularly species of Spiraea and Salix (willow). Large amounts  are used in producing certain dyes.</p><p>Salieri \sal-'yer-e\, Antonio (b. Aug. 18, 1750, Legnago, Republic of  Venice�d. May 7, 1825, Vienna, Austria) Italian composer. He moved to  Vienna in 1766 with the imperial court composer Florian Gassmann  (1729-74), and he remained there most of his career. On Gassmann�s  death, Salieri became composer and conductor of the Italian opera at the  imperial court, and later court kapellmeister (1788). Vienna�s most popu�  lar - opera composer for much of the last quarter of the 18th century, he  had many important students, including Ludwig van Beethoven, Franz Schu�  bert, and Franz Liszt. In addition to his more than 40 operas, he wrote much  other secular and sacred music. Though he and Wolfgang Amadeus  Mozart were rivals, there is no basis to the story that he poisoned Mozart,  and it is unlikely that he claimed to have done so.</p><p>Salinas \s3-'le-n9s\ City (pop., 2000: 151,060), western California, U.S.  Located in the Salinas valley east of Monterey, it was a crossroads on El  Camino Real, the old Spanish trail between San Diego and San Francisco.  It was settled in 1856 and became a cattle centre. The arrival of the  Southern Pacific Railroad in 1868 stimulated agricultural development.  Salinas was the birthplace of John Steinbeck, who often referred to it in  his books, especially in East of Eden.</p><p>Salinas \sa-'le-nas\ (de Gortari), Carlos (b.

Son of a Mexican senator,  Salinas earned a Ph.D. in economics at Harvard University and held vari�  ous governmental posts until he was elected president in 1988 by a slim  margin; vote fraud was widely charged. He pursued a program of eco�  nomic retrenchment and privatization, selling off hundreds of inefficient  state-owned corporations and spending part of the proceeds on infrastruc�  ture and social services. In 1991-92 his government co-negotiated the  North American Free Trade Agreement. The economic collapse immediately  following his term made him the target of bitter criticism. The assassina�  tion of his party�s nominee as his successor was linked to Salinas�s asso�  ciates, and Salinas fled to the U.S. and eventually Ireland. His brother  Raul, widely suspected of extensive corruption, was convicted in 1999 of  complicity in another assassination.</p><p>Salinger Vsa-lin-jorV J(erome) D(avid) (b.

One to two litres are produced daily by the salivary  glands. Small amounts are continually discharged into the mouth, but the  presence, smell, or even thought of food increases flow. Saliva�s main  function is to keep the inside of the mouth moist, making speech more  fluid, dissolving food molecules for taste, and easing swallowing. It also  helps control the body�s water balance, since lack of it stimulates thirst  when water intake has been low. Saliva reduces dental caries and infec�  tion by removing food debris, dead cells, bacteria, and white blood cells.</p><p>salivary gland \'sal-3-,ver-e\ Any of the organs that secrete saliva.  Three pairs of major glands secrete saliva into the mouth through distinct  ducts: the parotid glands (the largest), between the ear and the back of the  lower jaw; the submaxillary glands, along the side of the lower jaw; and  the sublingual glands, in the floor of the mouth near the chin. There are  also numerous small glands in the tongue, palate, lips, and cheeks.

He began to write after his political career ended c. 45 bc, becoming  one of the great Latin literary stylists, noted for his narrative writings  about political personalities, corruption, and party rivalry. His works,  whose influence pervades later Roman historiography, are Catiline�s War  (43^-2 bc), dealing with corruption in Roman politics; The Jugurthine  War (41�40), exploring party struggles in Rome in the late 2nd century  bc; and Histories , of which only fragments remain.</p><p>salmon Name that originally referred to the Atlantic salmon ( Salmo  salar ) and now also refers to six species of Pacific salmon (genus Onco-  rhynchus, family Salmonidae): chum, Chinook, pink, and sockeye salmon;  coho; and the cherry salmon (O. masu) of Japan. Adult salmon live at sea,  then migrate, fighting rapids and leaping high falls, to the stream where  they hatched to spawn. Pacific salmon die soon after spawning; many  Atlantic salmon live to spawn again.

Any of a wide range of mild to serious infections caused  by salmonellae are called salmonellosis, including typhoid and paratyphoid  fever in humans. Refrigeration prevents their reproduction but does not  kill them; as a result, many salmonellae can develop in foods, which, when  eaten, can cause gastroenteritis. Chickens are major reservoirs of salmo�  nella, and chicken and eggs are the principal source of human poisoning,  whose symptoms include diarrhea, vomiting, chills, and painful head�  aches. Other food sources include unpasteurized milk, ground meat, and  fish.</p><p>salmonellosis \ I sal-m3-,ne-To-s9s\ Any of several bacterial infections  caused by salmonella, including typhoid and similar fevers and gastroen�  teritis (see food poisoning). Meat from diseased animals carries the bac�  teria, and any food can pick it up from infected feces in the field or during  storage or from contaminated food or utensils during food preparation.  The source is often hard to trace. Eggs from infected hens can carry it  within, not just on the shells.

He studied law at the  University of Munich but soon abandoned his practice to pioneer in pho�  tojournalism. He specialized in photographing heads of state in unguarded  moments at international conferences and social gatherings. His purpose  was to show the human qualities of world leaders, who up to that time  had been stereotyped in stiff formal portraits. In May 1944 he was sent  to the concentration camp at Auschwitz, where he died.</p><p>Salomon Vsa-lo-monV Haym (b. 1740, Lissa, Pol.�d.

Forced to flee  Poland for his revolutionary activities, he arrived in New York in 1772  and soon became a successful merchant and financier. A supporter of the  patriot cause in the American Revolution, he was arrested and imprisoned  by the British. In 1778 he escaped to Philadelphia, where he opened a  brokerage office. He made loans in excess of $600,000 to help finance the  new government, extended interest-free private loans to James Madison,  Thomas Jefferson, James Monroe, and others, and obtained French loans to  the American government.</p><p>Salon \sa-Toii\ Official exhibition of art sponsored by the French gov�  ernment. It originated in 1667 when Louis XIV sponsored an exhibit of the  works of the members of the Royal Academy of Painting and Sculpture.  The Salon derives its name from the exhibition�s location in the Salon  d�Apollon of the Louvre Palace. After 1737 it became an annual event,  and in 1748 the jury system of selection was introduced. During the  French Revolution, the Salon was opened to all French artists, though  academicians continued to maintain near-total control over the teaching  and exhibition of art through most of the 19th century. In 1881 the new  Societe des Artistes Frangais began to oversee the Salon, and with the  growing importance of independent exhibitions of the works of avant-  garde artists, it gradually lost its influence and prestige.</p><p>Salon des Independants \sa- , l6 n -da-za 11 -da-pa n - , da n \ Annual unjur�  ied exhibition of the Societe des Artistes Independants, held in Paris since  1884.

Located at the southern tip of a pen�  insula that separates All Saints Bay from the Atlantic Ocean, it is one of  Brazil�s oldest cities, founded in 1549 as the Portuguese colonial capital.  At the centre of the sugar trade along the bay, it became a prize for pri�  vateers, and the Dutch captured it briefly in 1624. Retaken by the Portu�  guese, it became a major centre for the African slave trade. It has grown  continuously since 1940, and its port is one of the country�s finest. Impor�  tant industries include food and tobacco processing, ceramics, and ship�  building.</p><p>salvation In religion, deliverance from fundamentally negative condi�  tions, such as suffering, evil, death, or samsara, or the restoration or eleva�  tion of the natural world to a higher, better state. Eastern religions tend  to stress self-help through individual discipline and practice, sometimes  over the course of many lifetimes, though in Mahayana Buddhism bodhi-  sattvas and certain buddhas may act as intervening divine agents. In Chris�  tianity, Jesus is the source of salvation and faith in his saving power is  stressed. Islam emphasizes submission to God. Judaism posits collective  salvation for the people of Israel.</p><p>Salvation Army International Christian charitable movement. It was  founded in 1865 by William Booth, with the aim of feeding and housing  the poor of London. He adopted the name Salvation Army in 1878 and  established the organization on a military pattern. Members are called  soldiers, and officers earn ranks that range from lieutenant to brigadier.  Converts are required to sign Articles of War and to volunteer their ser�  vices. Doctrines are similar to those of other evangelical Protestant  denominations, though Booth saw no need for sacraments. The meetings  are characterized by singing and hand clapping, instrumental music, per�  sonal testimony, free prayer, and an open invitation to repentance. Head�  quartered in London, the Salvation Army now provides a wide variety of  social services in more than 100 countries.</p><p>salvia \'sal-ve-9\ Any of about 700 species of herbaceous and woody  plants that make up the genus Salvia, in the mint family.

Notable  buildings include Renaissance and Baroque houses, archiepiscopal pal�  aces, and a 17th-century cathedral.</p><p>sama \sa-'ma\ In Sufism, the practice of listening to music, chanting, and  dancing as a means of producing a state of religious ecstasy and mystical  trance. Practitioners hold that music prepares the soul for a deeper com�  prehension of divine realities and a better appreciation of divine music.  God, as the source of beauty, is taken to be approachable through these  activities because they contain or exemplify beauty. It is stressed that music  is only a means to approach the spiritual realm, and strong ascetic training  is required to ensure that music so employed does not arouse base instincts.</p><p>samadhi \so-'ma-de\ State of intense concentration or absorption of  consciousness, the product of meditation. In Hinduism, it is achieved  through Yoga, in which the consciousness is absorbed in the object of  meditation. In Buddhism, samadhi is the result of mind-development as  distinct from insight-development (see vipassana), and is attainable by  non-Buddhists as well as Buddhists. In Zen Buddhism, samadhi allows  the meditator to overcome dualistic subject-object awareness through  unity with the object of meditation.</p><p>Samar Vsa-,mar\ Island (pop., 2000: 1,517,585), east-central Philip�  pines.

It  was the scene of the rebellion of Yemelyan Pugacfiov against Catherine II  in 1773-74. Samara later became a major trade centre. Its growth was  stimulated during World War II by the relocation there of numerous gov�  ernment functions when Moscow was threatened by German attack. It is  highly industrialized and is the centre of a network of pipelines. Oil and  petrochemicals are the major industries.</p><p>Samaria \so-'mar-e-3\ Central region, ancient Palestine. Extending  about 40 mi (65 km) north-south and 35 mi (55 km) east-west, it was  bounded by Galilee to the north, Judaea to the south, the Mediterranean  Sea to the west, and the Jordan River to the east. It corresponds roughly  to the northern portion of the modern West Bank territory. Ancient  Shechem (near modern Nabulus) was the region�s crossroads and politi�  cal centre until the Assyrian conquest of Israel in the 8th century bc. The  town of Samaria, its capital, was built by King Omri c. 880 bc. It was  taken by Sargon II in c. 724-721 bc, and its inhabitants were transported  into captivity. It was rebuilt by Herod the Great, who renamed it Sebaste  in honour of the Roman emperor Augustus (Greek, Sebastos). In ad 6 the  region became part of the Roman province of Judaea.</p><p>Samaritan Member of a now nearly extinct Jewish community. Call�  ing themselves Bene-Yisrael (�Children of Israel�), or Shamerim (�Obser�  vant Ones�), they claim to be related to those Jews of ancient Samaria  who were not deported from Israel by the Assyrians in 722 bc. The Pen�</p><p>tateuch (first five books of the Old Testament) is their sole norm of reli�  gious observance. Jews who returned to their homeland after the  Babylonian Exile would not accept their help in building the Second Temple  of Jerusalem. Consequently, in the 4th century bc the Samaritans built their  own temple in Nabulus, at the base of Mount Gerizim, in the present-day  West Bank. The modern population (about 500 persons) is distributed  between Nabulus and the city of Holon in Israel. All live in semi-isolation,  marrying only within their own community. They pray in Hebrew but have  adopted Arabic as their vernacular.</p><p>Samarkand \,sa-m3r-'kand\ or Samarqand City (pop., 1999 est.:  362,300), east-central Uzbekistan.

The observance of  the samskaras is based on custom and on such texts as the Puranas, and  differs considerably according to region, caste, or family. The most gen�  erally accepted list of 16 traditional samskaras includes ceremonies for  conception, a male birth, name-giving, the upanayana, and marriage.  There is also a body of noncanonical samskaras performed by and for the  benefit of women.</p><p>Samson Israelite warrior hero of the Old Testament Book of Judges. His  mother had been told by an angel that she would bear a son whose life  would be dedicated to God and whose hair must never be cut. Samson per�  formed many powerful acts, including slaying a lion and moving the gates  of Gaza. When he revealed to a Philistine woman, Delilah, that his hair was  the source of his strength, she shaved his head while he was sleeping, leav�  ing him powerless. He was blinded and enslaved by the Philistines, but later  his strength was restored and he pulled down the pillars of a temple where  3,000 Philistines had gathered, killing them and himself.</p><p>Samuel (c. 11th century bc) Old Testament prophet, the first after Moses  and the last of the judges of ancient Israel. His story is told in two bib�  lical books (1 and 2 Samuel) that relate the history of Israel in the 11th�  10th century bc. During this period, the first monarchy of Israel was  established and the tribes of Israel united under a single kingdom with its  capital at Jerusalem. Samuel received a revelation that led to the instal�  lation of Saul as king, but later announced an oracle rejecting Saul and  secretly anointed David as king. Scholars dispute whether the historical  Samuel was the author of the two books that bear his name.</p><p>Samuel (d. Oct. 6, 1014) Tsar of Western Bulgaria (980-1014). Ruling  originally in Macedonia, he conquered Serbia, northern Bulgaria, Alba�  nia, and northern Greece. He revived the Bulgarian patriarchate and in  the 980s defeated Basil II. However, his struggle with the Byzantines con�  tinued until 1014, when Basil defeated Samuel�s army at the Battle of  Belasitsa. At Basil�s order, the 15,000 Bulgarian prisoners were blinded  and then returned to Samuel, who is said to have died of shock.</p><p>Samuel (of Mount Carmel and of Toxeth), Herbert Louis  Samuel, 1st Viscount (b.

His Foundations of Economic Analysis (1947) outlines a  basic theme of his work, the universal nature of consumer behaviour as  the key to economic theory. His studies included the dynamics of eco�  nomic systems, analyses of public goods, welfare economics, and public  expenditure. His most influential work was perhaps his mathematical for�  mulation of multiplier and accelerator effects and, in consumption analy�  sis, his development of the theory of revealed preference. His classic  Economics (1948) is the best-selling U.S. economics textbook of all time.  For his fundamental contributions to nearly all branches of economics, he  became in 1970 the third person to be awarded the Nobel Prize in Eco�  nomic Sciences.</p><p>samurai Member of the Japanese warrior class. In early Japanese his�  tory, culture was associated with the imperial court, and warriors were  accorded low status. The samurai became important with the rise in pri�  vate estates ( shoen ), which needed military protection. Their power  increased, and when Minamoto Yoritomo became the first shogun (mili�  tary ruler) of the Kamakura period (1192-1333), they became the ruling  class. They came to be characterized by the ethic of bushido, which  stressed discipline, stoicism, and service. Samurai culture developed fur�  ther under the Ashikaga shoguns of the Muromachi period (1338-1573).  During the long interval of peace of the Tokugawa period (1603-1867),  they were largely transformed into civil bureaucrats. As government  employees, they received a stipend that was worth less and less in the  flourishing merchant economy of the 18th�19th centuries in Edo (Tokyo)  and Osaka. By the mid-19th century, lower-ranking samurai, eager for  societal change and anxious to create a strong Japan in the face of West�  ern encroachment, overthrew the shogunal government in the Meiji Resto�  ration of 1868. Feudal distinctions were abolished in 1871. Some samurai  rebelled (see Saigo Takamori), but most threw themselves into the task of  modernizing Japan.

They are closely related to the  Khoekhoe. San languages belong to the Khoisan family. Two well-known  San groups are the !Kung (Ju) and the IGui. The San are, for the most  part, physically indistinguishable from the Khoekhoe or from their Bantu�  speaking neighbours. Traditional San society centres on the nomadic band  of related families. San shelters are semicircular structures of branches,  twigs, and grass; their equipment is portable, their possessions few and  light. They have traditionally hunted, using bows and snares, and gath�  ered wild vegetables, fruits, and nuts. Numbering in the tens of thousands,  most San have been restricted, because of historical and political factors,  to harsh, semiarid areas, and they work for wages on European farms or  serve other Africans, notably the Tswana.</p><p>San Vsan\, Saya orig. Ya Gyaw (b. Oct. 24, 1876, East Thayetkan,  Shewbo district, Burma�d. Nov. 16, 1931, Tharrawaddy) Political leader  of Burma (Myanmar). A Buddhist monk, physician, and astrologer in  Siam (Thailand) and Burma, he joined an extreme nationalist group dedi�  cated to organizing peasant discontent. Claiming the throne of Burma, he  had himself crowned in 1930 and initiated an anti-British revolt in the  Tharrawaddy district. Within two years the rebels, armed only with spears  and swords and protected by charms they believed would make them  invulnerable to bullets, were defeated by British troops with machine  guns; Saya San was captured, tried, and hanged. The revolt exposed the  precarious and unpopular position of the British in Burma.</p><p>San Andreas \,san-an-'dra-3s\ Fault Zone of transform faults at the  boundary between two tectonic plates in the western U.S. The fault runs  along the coast of northern California for more than 800 mi (1,300 km)  and passes seaward in the vicinity of San Francisco. Movement along the  fault is characterized by frequent earthquakes, including the major San  Francisco quake of 1906, when parts of the fault line moved as much as  21 ft (6.4 m); the less serious earthquake of 1989; and a destructive quake  centred in the Los Angeles suburb of Northridge in 1994.</p><p>San Antonio City (pop., 2000: 1,144,646), south-central Texas, U.S.  It is situated at the headwaters of the San Antonio River. Founded in 1718  by the Spanish as a mission on the site of a Coahuiltecan Indian village,  it was laid out as a town in 1731. The mission, called the Alamo, became  a military post in 1794; it was the site of a historic siege in 1836. In the  late 19th century, as the starting point of the Chisholm Trail, the town  became a major cattle centre. Military installations, especially for avia�  tion and aerospace, spurred the city�s rapid growth after 1940.

Son of a pro�  fessional soldier and colonial administrator, he was educated in Spain.  Initially he fought loyally for Spain against the Moors (1791), the British  (1798), and the Portuguese (1801), but in 1812 he returned to the New  World to help the revolutionaries. His greatest campaign was the libera�  tion of Lima, without which the independence of the Argentine provinces  could not have been secured. His bold strategy was to lead an army over  the Andes, a daunting undertaking. In 1817 he liberated Chile, which he  turned over to Bernardo O' Higgins, and proceeded to Peru by ship, where  he blockaded the chief port until the royalists withdrew. He then entered  Lima and declared the independence of Peru, though he lacked adequate  forces to subdue the royalists in the interior. The following year he met  with Simon Bolivar; what passed between them is unknown, but San Mar�  tin soon afterward went into exile in France, leaving Bolivar to complete  the liberation of Peru.</p><p>San Pedro Sula \san-'pa-thro-'su-la\ City (pop., 2001: 439,086), north�  western Honduras.

Most rock-forming minerals are found in sand, but  quartz is by far the most common. Most sands also contain a small quan�  tity of feldspar, as well as white mica. All sands contain small quantities  of heavy rock-forming minerals, including garnet, tourmaline, zircon,  rutile, topaz, pyroxenes, and amphiboles. In the pottery and glassmaking  industries very pure quartz sands are used as a source of silica. Similar  sands are used for lining the hearths of steel furnaces. Molds used in  foundries for casting metal are made of sand with a clay binder. Quartz  and garnet sands are used extensively as abrasives. Among ordinary  sand�s many uses, it is a basic ingredient of mortar, cement, and concrete.  See also tar sand.</p><p>Sand, \'sa n d,\ English \'sand\ George orig.

During child�  hood she gained a love of the coun�  tryside that would inform most of her  works. Married in 1822, she soon  tired of her husband, Casimir Dude-  vant, and began a series of liaisons;  her lovers included Prosper Merimee,</p><p>Alfred de Musset, and, most impor�  tantly, Frederic Chopin. She became  famous (under her pseudonym) with  her novel Indiana (1832), a protest  against conventions that bind an  unhappy wife to her husband. Lilia  (1833) extended her iconoclastic  views on social and class associa�  tions. Similar themes, along with her  sympathy for the poor, are evident in  her finest works, the so-called rustic  novels, including The Devil�s Pool (1846), The Country Waif( 1848), and  Little Fadette (1849).</p><p>Sand Creek Massacre or Chivington Massacre (Nov. 29,1864)  Surprise attack by U.S. troops on a Cheyenne camp.

Two  species, the sand tiger ( O. taurus) of  the Atlantic and the gray nurse (O. arenarius ) of Australia, are potentially  dangerous.</p><p>sandalwood Any semiparasitic plant of the genus Santalum (family  Santalaceae; the sandalwood family), or its wood, especially the wood of  the true, or white, sandalwood, Santalum album, which is used in mak�  ing furniture and from which oil used in making perfumes, soaps, candles,  and incense is derived. The approximately 10 species of Santalum are  distributed throughout South Asia and the islands of the South Pacific.  The sandalwood family contains more than 400 species of semiparasitic  shrubs, herbs, and trees in about 36 genera, found in tropical and temper�  ate regions. In some genera the leaves are reduced to scalelike structures.  The green leaves contain some chlorophyll, which allows the plants to  make food, but all sandalwoods are parasites to a certain extent, obtain�  ing water and nutrients from their hosts. Most, including S. album, are  root parasites, but some are stem parasites.</p><p>Sandalwood Island See Sumba</p><p>sandbar or offshore bar Submerged or partly exposed ridge of sand  or coarse sediment that is built by waves offshore from a beach.

Named for Cesar Augusto Sandino, a hero of Nica�  raguan resistance to U.S. occupation (1927-33), the group was founded  in 1962 to oppose the Somoza family�s dictatorship. They organized sup�  port among students, workers, and peasants. From bases in Honduras and  Costa Rica, they attacked the Nicaraguan National Guard. They split into  factions in the mid-1970s but reunited during the revolution of 1978-79  that finally succeeded in overthrowing Pres. Anastasio Somoza. A junta  headed by Daniel Ortega led the Sandinista government (1979-90), which  implemented literacy and community health programs. In an effort to  topple the government, the U.S. imposed a trade embargo, pressured inter�  national lending institutions to withhold aid, and trained and supported  the contras.

He served as secretary of state for the north (1763-65,  1770-71) and led the prosecution of John Wilkes. Appointed first lord of  the Admiralty during the American Revolution, he was criticized for keep�  ing much of the British fleet in European waters to avoid French attack.  His promotion of exploration led Capt. James Cook to name the Sandwich  Islands (later Hawaii) after him in 1778.

Andrea Contucci (b. c.</p><p>1467, Monte San Savino, Republic of Florence�d. 1529, Monte San  Savino) Italian sculptor. The fine detail and high emotional pitch of his  marble Altar of the Sacrament in Florence�s Santo Spirito (1485-90)  typify his early work; his marble Baptism of Christ (1502), above one of  the Baptistery doors in Florence, marks a shift to High Renaissance style  with its dignified poses and strong but controlled emotion. His tombs for  two cardinals in Rome�s Santa Maria del Popolo (completed 1509) were  his most influential innovation, with their triumphal-arch form and the  novel sleeping attitude of the deceased cardinals. His works display the  transition from early to High Renaissance, and his graceful style acted as  a counterbalance to Michelangelo�s titanic, muscular sculpture throughout  the 16th century.</p><p>Sansovino V.san-so-'ve-noV, Jacopo orig.

After the sack of Rome in 1527 he fled to Venice, where he was  appointed state architect (1529). His Library of St. Mark�s (begun 1537)  is one of the major architectural works of the 16th century. His vivid  sculptures were often important decorative elements of his buildings. His  best-known statues are the colossal figures of Mars and Neptune on the  staircase of the Doges� Palace (1554-66).

The principal themes of her poetry are  personal and reflect the activities and atmosphere of the thiasos. Her writ�  ing, mostly vernacular and not formally literary, is concise, direct, pic�  turesque, and various. It includes nuptial songs and an expression of her  love for other women, which produced the word lesbian (from the island�s  name).

Thou�  sands of structures made of basalt blocks, called nuraghi, are a dominat�  ing feature of the island. These truncated conic structures of blocks taken  from extinct volcanoes were built in prehistoric times without any mor�  tar. Some date to c. 1500^100 bc. Phoenicians were Sardinia�s first  recorded settlers c. 800 bc. Greeks and Carthaginians followed; Roman  rule began in 238 bc. In the early Middle Ages Pisa and Genoa struggled  over its domination. The kingdom of Sardinia, centred on the lands of  Piedmont in northwestern Italy and the island of Sardinia, was ruled by  the house of Savoy from 1720 until the unification of Italy in 1861. Agri�  culture, fishing, and mining are economic mainstays of the island.</p><p>Sardinian language Romance language spoken in Sardinia, the most  similar to Vulgar Latin of the modem Romance languages. Its only stan�  dard form is the sardo illustre , a literary language used mostly for folk  verse. Italian is the island�s official language, and few literary works exist  in Sardinian. The earliest written materials date from c. 1080.</p><p>Sardis Vsar-dssV or Sardes \'sar-dez\ Ancient city, Anatolia. Located  east of Smyrna (modern Izmir), it was the chief city and capital of the  kingdom of Lydia from the 7th century bc and the first city where gold and  silver coins were minted. It fell to the Persians c. 546 bc and passed to  the Romans in 133 bc. Destroyed by an earthquake in ad 17, it was rebuilt  and remained one of the great cities of Anatolia until the later Byzantine  period. It was obliterated by Timur in 1402. Its ruins include the ancient  Lydian citadel, but excavations have uncovered more remains of the Hel�  lenistic and Byzantine city than of the ancient Lydian town.</p><p>Sardou \sar-'du\, Victorien (b. Sept. 5, 1831, Paris, France�d. Nov.  8, 1908, Paris) French playwright. He owed his initial success to the  actress Pauline Dejazet, for whom he wrote several of his 70 works,  including A Scrap of Paper (1860). Several later works, including Fedora  (1882), were written for Sarah Bernhardt. His La Tosca (1887) was  adapted by Giacomo Puccini as an opera. His last success was Madame  Sans-Gene (1893). In 1877 he was elected to the Academie Fran^aise.  His plays rely heavily on theatrical devices and plot contrivances, and he  is remembered as a craftsman of the bourgeois drama that George Bernard  Shaw belittled as �Sardoodledom.�</p><p>Sarekat \'sar-o-kat\ Islam First nationalist political party in Indonesia  to gain wide popular support. Founded in 1912 to promote the interests  of Muslim merchants, it soon began working for the self-government of  the Dutch East Indies. Its religious appeal helped it grow rapidly, and by  1916 it claimed 350,000 members. As it became increasingly involved in  revolutionary activities, communist elements entered the organization. A  struggle for power ensued between religious leaders and communists,  which culminated in the party dividing in 1921. Sarekat Islam declined  after the departure of its left wing.</p><p>Sarema See Saaremaa</p><p>Sargasso Sea Body of still water in the North Atlantic Ocean. Ellip�  tical in shape and strewn with a brown floating seaweed of the genus Sar-  gassurn, it lies between the parallels 20� and 35� N and the meridians 30�  and 70� W and encompasses the Bermuda islands. It was first mentioned  by Christopher Columbus, who crossed it in 1492. The presence of the sea�  weed suggested the proximity of land and encouraged him to continue,  but many early navigators feared becoming entangled in the floating veg�  etation and turned back.</p><p>sargassum \sar-'ga-sum\ Any of the brown algae that make up the  genus Sargassum. They are adapted for a free-floating tropical environ�  ment, even though many species grow attached to rocks along the coast.  The Sargasso Sea, a free-floating mass of seaweed (mostly S. natans),  occurs in the Atlantic Ocean. Sargassums are also known as sea holly</p><p>because of their highly branched stems with hollow, berrylike floats and  many leaflike, sawtooth-edged blades. They are used as fertilizer in New  Zealand and as a component of soups and soy sauce in Japan.</p><p>Sargent, John Singer (b. Jan. 12, 1856, Florence, Italy�d. April 15,  1925, London, Eng.) U.S.-British painter. Son of wealthy American par�  ents, he was born in Italy and grew up in Europe, not seeing the U.S. until  1876. Having studied painting in Paris, in 1879 he traveled to Madrid and  Haarlem to study the works of Diego Velazquez and Frans Hals; his finest  works were painted soon afterward. Best known is his portrait Madame  X, which created a scandal at the 1884 Salon; critics found it eccentric  and erotic, and the sitter�s mother claimed it made her daughter a laugh�  ingstock. Discouraged, he moved permanently to London, though he often  visited the U.S. Not until about 1887 did he achieve the acclaim he was  to enjoy in the U.S. and England the rest of his life. His elegant portraits  created an enduring image of high society of the Edwardian age; the best,  painted with his slashing brushstrokes, capture his subjects in revealing,  off-guard moments. He largely gave up portraiture in 1907 and devoted  the rest of his life to murals and landscapes.</p><p>Sargon Vsar-gan\ (fl. 23rd century bc) Ancient Mesopotamian ruler (r.  2334-2279 bc). What is known of him comes from legends and tales; his  capital city, Agade, has never been located. Perhaps originally a royal  cupbearer, he came to prominence by defeating a Sumerian king, thereby  attaining an empire in southern Mesopotamia and becoming the first  emperor whose native tongue was Akkadian rather than Sumerian. He  enlarged the empire from Iraq to Anatolia, and trade flourished with the  Indus valley, Oman, the Persian Gulf coast, Cappadocia, and perhaps  Greece.</p><p>Sargon II (d. 705 bc) Assyrian king (r. 721-705 bc). He continued the  empire-building work of his pre�  sumed father, Tiglath-pileser III. One  of his aims was to prove the might  of the Assyrian god Ashur by enlarg�  ing the empire he had inherited. His  conquests ranged from southern  Babylonia to Armenia and the Medi�  terranean. He probably died in battle  in northwestern Persia. His son, Sen�  nacherib, succeeded him.</p><p>Sarmatian \sar-'ma-sh9n\ Any  member of a people originally of Ira�  nian stock who migrated from Cen�  tral Asia to the Ural Mountains in the  6th-4th centuries bc and settled in  southern European Russia and the  eastern Balkans. Closely related to  the Scythians, they were expert  horsemen and warriors and gained  wide influence through administra�  tive and political astuteness. Women  fought alongside men and may have  inspired Greek tales of Amazons. By  the 5th century bc they controlled the land between the Urals and the Don,  and by the 2nd century they had conquered the Scythians to rule almost  all southern Russia. Allied with Germanic tribes, they continued to pose  a threat to the West until the 1st century ad. After invading Dacia and the  lower Danube, they were overrun by the Goths. Many joined the Gothic  invasion of western Europe. Sarmatia was destroyed by Huns after ad 370.  Their descendants cannot be traced after the 5th century.</p><p>Sarmiento Nsarm-'yan-toN, Domingo Faustino (b. Feb. 14, 1811,  San Juan, Viceroyalty of Rio de la Plata�d. Sept. 11, 1888, Asuncion,  Para.) Educator, statesman, writer, and president of Argentina (1868-74).  A rural schoolteacher, he entered provincial politics and was exiled to  Chile by Juan Manuel de Rosas for his outspokenness. There he became  an important figure in journalism and education. In his important book  Facundo (1845), he denounced the Rosas dictatorship and the culture of  the gauchos. He returned to Argentina to help overthrow Rosas in 1852.  Elected president in 1868, he ended the Paraguayan War, developed the  public school system, established technical and professional schools, and  upheld civil liberties.</p><p>Sarnoff, David (b.

In 1912 he heard the distress  signal from the sinking Titanic and  remained at his instrument for 72  hours relaying news. In 1921 he  became general manager of the  newly formed Radio Corp. of  America (RCA Corp.). He had pro�  posed the first commercially mar�  keted radio receiver in 1916, and by  1924 it had earned $80 million in  sales. He formed the radio network  NBC in 1926. Perceiving television�s  potential, he set up an experimental  television station (1928) and demon�  strated the new medium at the New  York World�s Fair (1939). During  World War II he was a communica�  tions consultant to Gen. Dwight D. Eisenhower and was made a brigadier  general. President of RCA (1930-47), he served as chairman of the board  until 1970.</p><p>Saro-Wiwa V.sa-ro-'we-woV Ken orig. Kenule Beeson Saro-  Wiwa (b. Oct. 10, 1941, Bori, near Port Harcourt, Nigeria�d. Nov. 10,  1995, Port Harcourt) Nigerian writer and activist. He taught at the Uni�  versity of Lagos and held government office before turning to writing.  His first novels were Songs in a Time of War and Sozaboy (both 1985);  his television series Basi and Company satirized the Nigerian desire to  get rich with little effort. He also wrote poetry, children�s stories, and a  newspaper column. His support of the Ogoni people against the oil indus�  try put him at odds with the government; he was spuriously charged with  four murders and executed despite worldwide protest.</p><p>Saronic \s9-'ra-nik\ Gulf Gulf of the Aegean Sea, southeastern coast of  Greece. Some 50 mi (80 km) long and 30 mi (50 km) wide, it separates  Attica and the Peloponnese and is linked to the Gulf of Corinth by the  Corinth Canal. It was the site of a major Athenian victory over the Per�  sians in 480 bc (see Battle of Salamis). Its ports include Piraeus and Megara.</p><p>Saroyan \s3-'r6i-3n\, William (b. Aug. 31, 1908, Fresno, Calif.,  U.S.�d. May 18, 1981, Fresno) U.S. writer. Saroyan was the largely  self-educated son of an Armenian immigrant. He made his initial impact  during the Depression with brash, original, and irreverent stories celebrat�  ing the joy of living in spite of poverty, hunger, and insecurity. Much of  his fiction is based on his childhood and family. His story collections  include The Daring Young Man on the Flying Trapeze (1934), Inhale and  Exhale (1936), and My Name is Aram (1940). His other works include the  play The Time of Your Life (1939, Pulitzer Prize) and The Human Com�  edy (1943), a sentimental novel of life in a small California town.</p><p>Sarpi \'sar-pe\, Paolo (b. Aug. 14, 1552, Venice�d. Jan. 14, 1623,  Venice) Italian patriot, scholar, and state theologian. At age 20 Sarpi  became court theologian to the duke of Mantua, a post that gave him lei�  sure to study Greek, Hebrew, mathematics, anatomy, and botany. Later,  as consultor to the government, he incurred the wrath of Pope Paul V by  supporting Venice�s right to restrict church construction in the city and to  try priests accused of crimes unrelated to religion (e.g., murder) in the  state�s courts. His History of the Council of Trent (1619), an important  work decrying papal absolutism, was published under a pseudonym;  though placed on the Index librorum prohibitorum, it went through several  editions and five translations in 10 years.</p><p>Sarraute \sa-'r6t\, Nathalie orig. Nathalie llyanova Tcher-  niak (b. July 18, 1900, Ivanova, Russia�d. Oct. 19, 1999, Paris, France)  French novelist and essayist. She practiced law until c. 1940, when she  became a full-time writer. Tropismes (1939), a collection of sketches,  introduced her idea of tropisms, the �things that are not said and the  movements that cross our consciousness very rapidly.� An early practi�  tioner and leading theorist of the nouveau roman (�new novel�), the  French antinovel, she discarded conventions of plot, chronology, charac�  terization, and point of view. Her novels�including Portrait of a Man  Unknown (1948), Martereau (1953), Le planetarium (1959), and Here  (1997)�and her plays focus on the unspoken �subconversations� in  human interactions.</p><p>SARS in full severe acute respiratory syndrome Highly con�  tagious respiratory illness characterized by a persistent fever, headache,  and bodily discomfort, followed by a dry cough that may progress to great  difficulty in breathing. SARS appeared in November 2002 in Guangdong  province, China, and was brought to Hong Kong in February 2003. As it  spread from there to other countries of East Asia and the world, health  authorities instituted an unprecedented series of control measures, includ�  ing quarantines and prohibitions on travel, and in June 2003 the global  outbreak was declared to be contained. By that time more than 8,000 cases  had been reported, and some 800 people had died. SARS is believed to  be caused by a mutant coronavirus, a type usually associated with pneu�  monia and the common cold. A specific vaccine has not been developed.  Treatment is usually restricted to easing the patient�s symptoms�  providing mechanical ventilation if necessary�until the illness has run  its course.</p><p>sarsaparilla X.sas-ps-'ri-bV Aromatic flavouring agent originally made  from the dried roots of several tropical smilax vines. Native to the south�  ern and western coasts of Mexico to Peru, the plants are large, perennial,  climbing or trailing vines with short, thick, underground stems that pro�  duce many prickly, angular, aboveground stems supported by tendrils.  Once a popular tonic, sarsaparilla now is blended with wintergreen and  other flavours and used in root beer and other carbonated beverages, or  to flavour and mask the taste of medicines. In North America, the strongly  aromatic roots of the wild sarsaparilla (Aralia nudicaulis) and false, or  bristly, sarsaparilla (A. hispida ), of the ginseng family, are sometimes sub�  stituted for true sarsaparilla.</p><p>Sarto, Andrea del See Andrea del Sarto</p><p>Sartre VsartrA, Jean-Paul (b. June 21, 1905, Paris, France�d. April  15, 1980, Paris) French philosopher,  novelist, and playwright, the fore�  most exponent of existentialism. He  studied at the Sorbonne, where he  met Simone de Beauvoir, who became  his lifelong companion and intellec�  tual collaborator. His first novel,</p><p>Nausea (1938), narrates the feeling  of revulsion that a young man expe�  riences when confronted with the  contingency of existence. Sartre used  the phenomenological method of  Edmund Husserl (see phenomenology)  with great skill in three successive  publications: Imagination: A Psy�  chological Critique (1936), Sketch  for a Theory of the Emotions (1939),  and The Psychology of Imagination  (1940). In Being and Nothingness  (1943), he places human conscious�  ness, or nothingness ( neant ), in  opposition to being, or thingness  {etre)\ consciousness is nonmatter and thus escapes all determinism. In his  postwar treatise Existentialism and Humanism (1946) he depicts this radi�  cal freedom as carrying with it a responsibility for the welfare of others.  In the 1940s and �50s he wrote many critically acclaimed plays�  including The Flies (1943), No Exit (1946), and The Condemned ofAltona  (1959)�the study Jean Genet (1952), and numerous articles for Les Temps  Modernes, the monthly review that he and de Beauvoir founded and  edited. A central figure of the French left after the war, he was an out�  spoken admirer of the Soviet Union�though not a member of the French  Communist Party�until the crushing of the Hungarian uprising by Soviet  tanks in 1956, which he condemned. His Critique of Dialectical Reason  (1960) faults Marxism for failing to adapt itself to the concrete circum�  stances of particular societies and for not respecting individual freedom.  His final works include an autobiography, The Words (1963), and Flau�  bert (4 vol., 1971-72), a lengthy study of the author. He declined the 1964  Nobel Prize for Literature.</p><p>Sarvastivada \s3r-,vas-ti-'va-d9\ One of the 18 schools of Hinayana  Buddhism that developed during the first four or five centuries after the  Buddha�s death.

Founded by Ardashlr I (r. ad 224-241) and named  for his ancestor Sasan (c. 1st century ad), it replaced the Parthian empire  (see Parthia). Its capital was Ctesiphon. The dynasty battled the Roman  Republic and Empire and its successor the Byzantine Empire in the west and  the Kushans and Hephthalites in the east throughout much of its exist�  ence. In the 3rd century its empire stretched from Sogdiana and Georgia  to northern Arabia, and from the Indus River to the Tigris and Euphrates  rivers. Traditions of the Achaemenian dynasty were revived, Zoroastrian�  ism was reestablished as the state religion, and art and architecture expe�  rienced a renaissance. Its important rulers included Shapur I (d. 272),  Shapur II (309-379), Khosrow I, and Khosrow II. The Sasanids were the  last native Persian dynasty before the Arab conquest of the region in the  late 7th century.</p><p>Saskatchewan \sas-'ka-ch9-,wan\ Province (pop., 2000: 978,933),  western Canada. It is bounded to the north by the Northwest Territories,  to the east by Manitoba, to the south by the U.S. state of Montana, and  to the west by Alberta. The capital of Saskatchewan is Regina. A plains  region, with prairie to the south and wooded country to the north, it sup�  ports rich and varied wildlife. The Cree Indians inhabited the region for  some 5,000 years before it was claimed by the Hudson's Bay Co., which  controlled the area from 1670 until it surrendered the land to the British  in 1868. It was part of Rupert�s Land (the territories granted to the Hud�  son�s Bay Co.) until 1869, and in 1870 it became part of the Dominion  of Canada. From 1882 the extension of the railroad brought large num�  bers of European settlers. The province was created in 1905. Its economy  is based on oil, gas, and potash production, grains, and livestock. The  largest city is Saskatoon.</p><p>Saskatchewan, University of Canadian public university in Saska�  toon, founded in 1907.

The  combined streams continue east 340 mi (550 km) to enter Lake Winnipeg.  Once important as a fur-trading route, it now provides hydroelectric power  and irrigation.</p><p>Saskatoon \,sas-k9-'tun\ City (pop., 2001: 196,811), south-central  Saskatchewan, Canada. It was founded on the Saskatchewan River in 1883  as the proposed capital of a temperance colony. It grew rapidly follow�  ing the arrival of the railroad in 1890 and the town�s amalgamation with  two adjoining settlements in 1906. Saskatchewan�s largest city, it is a cul�  tural and educational centre and a major transportation hub and distribu�  tion centre. Its educational institutions include the University of  Saskatchewan (founded 1907).</p><p>Sasquatch See Bigfoot</p><p>sassafras Vsa-s3-,fras\ North American tree ( Sassafras albidum) of the  laurel family. The aromatic leaf, bark, and root are used as a flavouring, as  a traditional home medicine, and as a tea. The aromatic roots yield about  2% oil of sassafras, once the characteristic ingredient of root beer. The  tree is native to sandy soils from Maine to Ontario and Iowa and south  to Florida and Texas. It is usually small but may attain a height of 65 ft  (20 m) or more. It has furrowed bark, bright green twigs, small clusters  of yellow flowers followed by dark blue berries, and three distinctive  forms of leaves, often on the same twig: three-lobed, two-lobed (mitten�  shaped), and entire.</p><p>Sassandra River \s9-'san-dro\ River, western Cote d�Ivoire.

It is divided into two principal  sections, verbal and mathematical. Promulgated largely through the efforts  of James B. Conant as a means of promoting merit-based (rather than  class-based) college admissions, it was administered to few students  before the end of World War II but by the end of the 20th century was  taken by millions each year. Scores declined as the test came to be more  widely administered, and in 1995 the score of 500 for each section (mid�  way between the extremes of 200 and 800) was reestablished as the actual  mean score of those tested. The test, which most colleges use as one mea�  sure of an applicant�s ability, has been denounced as biased in favour of  men and the white middle class. Other critics claim that the SAT is inad�  equate for testing various important capacities.</p><p>satanism Worship of Satan, or the devil, the personality or principle  regarded in the Judeo-Christian tradition as embodying absolute evil, in  complete antithesis to God. Cults associated with satanism have been  documented, however sketchily, back to the 17th century. Their central  feature is the black mass, a corrupted and inverted rendition of the Chris�  tian Eucharist. Practices are said to include animal sacrifice and deviant  sexual activity. Worship is motivated by the belief that Satan is more  powerful than the forces of good, and so is more capable of bringing about  the results sought by his adherents.</p><p>satellite Natural object (moon) or spacecraft (artificial satellite) orbiting  a larger astronomical body. Most known natural satellites orbit planets;  the Earth�s Moon is the most obvious example and was the only one  known until the discovery of the Galilean satellites of Jupiter in 1610. All  the solar system�s planets except Mercury and Venus have moons, which  vary greatly in size, composition (from rock to mostly ice), and activity  (from cold and inert to volcanic). Some asteroids are also known to have  their own moons. The first artificial satellite, Sputnik 1, was launched into  orbit around Earth in 1957. Since then, thousands have been sent into orbit  around Earth as well as the Moon, Venus, Mars, Jupiter, and other bod�  ies. Artificial satellites are used for scientific research and other purposes,  such as communication (see communications satellite), weather forecast�  ing, Earth resources management, and military intelligence.

May 17, 1866,  Honfleur, Calvados, France�d. July 1, 1925, Paris) French composer. He  studied at the Paris Conservatoire (1879-82) but dropped out. From 1888  he played piano at the cafe Le Chat Noir; he became associated with the  Rosicrucian movement in about 1890 and wrote several works under its  influence. Living in austere poverty in a working-class district, he began  to gain prominence in 1911, when he was lauded as a forerunner of mod�  em music; his admirers included Claude Debussy, Jean Cocteau, and the  group of composers known as Les Six. Satie�s music represents the first  definite break with 19th-century French Romanticism; it also stands in  opposition to Impressionism (a movement he frequently mocked). His  mostly short piano works are spare and unconventional, and they char�  acteristically take the form of parody, with flippant titles such as Three  Pieces in the Form of a Pear (1903).</p><p>satin Fabric constructed by the satin weaving method, one of the three  basic textile weaves. Satin weave superficially resembles twill but does not  have the regular step in each successive weft that characterizes twills.  Thus, there is no strong diagonal line, and the fabric is smooth-faced, with  an unbroken surface made up of long floating warp yams. Because satins  are susceptible to the wear caused by rubbing and snagging, they are con�  sidered luxury fabrics. Satin is made in different weights for various uses,  including dresses (particularly evening wear), linings, bedspreads, and  upholstery. Though originally of silk, it may be made of yams of other  fibres.</p><p>satire Artistic form in which human or individual vices, folly, abuses,  or shortcomings are held up to censure by means of ridicule, derision,  burlesque, irony, or other methods, sometimes with an intent to bring</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Satnami sect &#x25BA; Sa'ud I 1689</p><p>about improvement. Literature and drama are its chief vehicles, but it is  also found in such mediums as film, the visual arts (e.g., caricatures), and  political cartoons. Though present in Greek literature, notably in the works  of Aristophanes, satire generally follows the example of either of two  Romans, Horace or Juvenal. To Horace the satirist is an urbane man of  the world who sees folly everywhere but is moved to gentle laughter rather  than to rage. Juvenal�s satirist is an upright man who is horrified and  angered by corruption. Their different perspectives produced the sub�  genres of satire identified by John Dryden as comic satire and tragic sat�  ire.</p><p>Satnami sect \,s3t-'na-me\ Religious community in India that chal�  lenges political and religious authority by worshiping the supreme god  Satnam. Combining practices from Islam and Hinduism, Satnamis typically  reject both the worship of images and the caste system, while retaining  an underlying orthodox Vedanta philosophy. Modern Satnamis are con�  fined almost entirely to the low-status Camar caste, and they advocate  social equality as well as ethical and dietary self-restraint.</p><p>Sato \'sa-to\, Eisaku (b.

For his policies on nuclear weapons, which led to Japan  signing the nuclear nonproliferation treaty, he shared the 1974 Nobel Prize  for Peace. As prime minister Sato improved relations with other Asian  countries and oversaw the return of the Ryukyu Islands from U.S. to  Japanese jurisdiction.</p><p>satrap Provincial governor in the Achaemenian empire. Darius I (r. 522-  486 bc) established 20 satrapies with an annual tribute. Appointed by the  king, satraps were usually of the royal family or Persian nobility and held  office indefinitely. They collected taxes, were the highest judicial author�  ity, and were responsible for internal security and for raising and main�  taining an army. Controls guarded against the abuse of power, but after  the mid 5th century bc, with central authority weakened, satrapies became  virtually independent. Alexander the Great and his successors retained the  satraps.</p><p>Satsuma \'sat-su-,ma\ Japanese feudal domain ( han ) in southern  Kyushu noted for its role in Japan�s modernization. Satsuma (part of  modern-day Kagoshima prefecture) was ruled by the Shimazu family  from the end of the 12th century to the AAeiji Restoration in 1868. In 1609  the family had conquered the Ryukyu Islands, and trade with the Ryukyus  continued during the Tokugawa period, when the rest of the country was  forbidden contact with the outside world. This trade both enriched Sat�  suma and provided experience with foreign affairs that would prove use�  ful in the 19th century when Western powers started pressuring Japan to  end its isolation. The domain also developed expertise in Western learn�  ing: Shimazu Shigehide (1745-1833) founded schools of medicine, math�  ematics, and astronomy; Shimazu Nariakira (1809-58) adopted Western-  style military techniques and armaments. These advantages, along with a  traditional enmity toward the Tokugawa family, put the men of Satsuma  in a prime position to become leaders in the movement to overthrow the  shogunal government.

Though it is sometimes possible to bring about super�  saturation (a concentration exceeding the equilibrium value), such solu�  tions or vapours are unstable and spontaneously revert to the saturated  state, accompanied by the transformation of the excess material to the  solid or liquid form (precipitation).

His wife was Ops, the goddess of plenty, and his children included Juno,  Neptune, and Ceres. His festival, Saturnalia (beginning December 17),  became the most popular Roman festival; its influence is still felt in the  celebration of Christmas and the Western New Year. During Saturnalia, all  business transactions were suspended, presents were exchanged, and  slaves were given token freedom. The remains of Saturn�s temple are  located in the Forum in Rome. Saturday is named for Saturn.</p><p>Saturn Sixth planet from the Sun, named for the Roman god of sowing  and seed. The second largest nonstellar object in the solar system after</p><p>Jupiter, it is about 95 times as massive as Earth and has more than 700  times its volume. Saturn�s outer layers are gaseous, mainly hydrogen.  Models of its interior suggest a rock-and-ice core surrounded by a shal�  low layer of liquid metallic hydrogen encased by an envelope of molecu�  lar hydrogen. Its mean density, about 70% that of water, is the lowest of  any known object in the solar system. Saturn has at least 47 moons  (including Titan, the largest) and an extensive ring system, with several  main sections visible from Earth with a telescope. Saturn�s rings, first  observed in 1610 by Galileo, are made up of countless separate particles  ranging mainly from inches to many feet in size but also including dust  in some regions. Water ice probably constitutes most of the ring material.  Saturn�s day is about 10.6 hours; its year is 29.4 Earth years. Its rapid  rotation, acting on electric currents in the core, generates a strong mag�  netic field and large magnetosphere. Saturn�s fast spin also makes it the  most flattened (oblate) of the planets; its polar diameter of 67,560 mi  (108,728 km) is 10% smaller than its equatorial diameter. Its average dis�  tance from the Sun is 887 million mi (1.43 billion km).</p><p>Saturn Any of a series of large two- and three-stage launch vehicles for  spacecraft, developed by the U.S. beginning in 1958 and first flight-tested  in 1961.

The consul, Marius, initially supported  him but later withdrew his backing. When Saturninus and his followers  seized the Capitoline Hill, Marius restored order, locking the leaders of  the action in the Senate house. Their enemies tore off the roof and stoned  them to death. The Senate then rescinded most of Saturninus�s legisla�  tion, but his land grants seem to have been recognized.</p><p>satyagraha V.sot-'ya-gro-hoX Philosophy of nonviolent protest, or pas�  sive resistance.

Satyagraha seeks to conquer through submission.  It involves refusing to submit to or cooperate with anything perceived as  wrong, while adhering to the principle of nonviolence in order to main�  tain the tranquillity of mind required for insight and understanding.

In the 18th century Muhammad ibn Sa'ud (d. 1765), chief  of an Arabian village that had never fallen under control of the Ottoman  Empire, rose to power together with the Wahhabi religious movement. He  and his son 'Abd al-'AzIz I (r. 1764-1803) conquered much of Arabia;  Sa'ud I (r. 1803-14) conquered Medina in 1804 and Mecca in 1806. The  Ottoman sultan induced the viceroy of Egypt to crush the Sa'udls and  Wahhabis, which was accomplished by 1818. A second Sa'ud! state was  formed in 1824 by Muhammad ibn Sa'ud�s grandson Turk! (r. 1823-34),  who made Riyadh his capital. When Turkl�s son Faysal (r. 1843-65) died,  succession disputes led to civil war. Power did not return to Sa'ud! hands  until 1902, when Ibn Sa'ud recaptured Riyadh. He established the king�  dom of Saudi Arabia by royal decree in 1932.

The largest petroleum producer of the Orga�  nization of Petroleum Exporting Countries (OPEC) and one of the leading  oil exporters in the world, Saudi Arabia has reserves that represent one-  fourth of the world total. Its other products include natural gas, gypsum,  dates, wheat, and desalinated water. It is a monarchy; its head of state and  government is the king, assisted by the crown prince. Saudi Arabia is the  historical home of Islam. During premodern times, local and foreign rul�  ers fought for control of the region; in 1517 the Ottoman Empire attained  nominal control of most of the peninsula. In the 18th�19th century an  Islamic reform group known as the Wahhabi joined with the Sa'Gd dynasty  to take control of most of central Arabia; they suffered political setbacks  but regained most of their territory by 1904. The British held Saudi lands  as a protectorate (1915-27), after which they acknowledged the sover�  eignty of the Kingdom of the Hejaz and Nejd. The two kingdoms were</p><p>unified as the Kingdom of Saudi Arabia in 1932.

All that is known of Saul comes from the biblical books  of Samuel I and II. He was anointed king by the prophet Samuel, as a  concession to popular pressure, after delivering the town of Jabesh-Gilead  from Ammonite oppression. Samuel�s rejection of Saul and Saul�s jeal�  ousy of David led to Saul�s decline.

Known in  ancient times in various places, saunas are most closely identified with  the Finnish people, who made saunas a national tradition. Typically, a  wooden hut containing rows of flat stones is built near the edge of a lake.  Wood is burned to heat the stones, and, when the stones are hot, cold  water is thrown on them to create steam. The unclothed bathers sit on  wooden benches in the steam-filled hut, then beat themselves with  branches until their skin is red and tingling, and dive into the cold water  or (in winter) roll in the snow. These extreme temperature changes are  thought to have a beneficial effect on the circulation. In an adapted form,  saunas are popular today in gymnasiums and health clubs.</p><p>Saura \'sau-ra\ (Atares), Carlos (b. Jan. 4, 1932, Huesca, Spain)  Spanish film director.

The order includes all carnivorous  and some giant herbivorous dinosaurs. Saurischians evolved from small  bipedal dinosaurs called thecodonts; they first appeared in the Late Trias-  sic epoch (227-206 million years ago). The order consists of three sub�  orders: theropods, sauropods, and staurikosaurs (suborder Staurikosauria).

The sauropods include the  largest of all dinosaurs and the largest land animals that ever lived. They  existed from the Late Triassic Epoch into the Cretaceous Period (227-65  million years ago). All species had a small head, extremely long neck,  massive body, thick, pillarlike legs, and a very long, tapering, whiplike  tail. With their weak, sparse teeth, they cropped vegetation from even the  tallest trees, apparently depending on swallowed stones or bacteria in the  gut to digest plant matter. Species ranged from 50 ft (15 m) long to the  98-ft (30-m) Brachiosaurus, which weighed 80 metric tons.

Sausage meat may be eaten  fresh, smoked, dried, or pickled. It may be mixed with other meats and  additives such as cereals, vegetable starch, soy flour, preservatives, arti�  ficial colourings, salt, and various herbs and spices. Casings may be intes�  tine, paraffin-treated fabric bags, or synthetic sleeves of plastic or  reconstituted collagen. All but dry (cured) sausages require refrigerated  storage.

Savings may take the form of bank deposits and cash holdings or secu�  rities. How much individuals save is affected by their preferences for  future over present consumption and their expectations of future income.  If individuals consume more than the value of their income, then their  saving is negative and they are said to be dissaving. Individual saving  may be measured by estimating disposable income and subtracting cur�  rent consumption expenditures. A measure of business saving is the  increase in net worth shown on a balance sheet. Total national saving is  measured as the excess of national income over consumption and taxes.  Saving is important to economic progress because of its relation to invest�  ment: an increase in productive wealth requires that some individuals  abstain from consuming their entire income and make their savings avail�  able for investment.</p><p>savings and loan association Financial institution that accepts  savings from depositors and uses those funds primarily to make loans to  home buyers. Savings and loan associations (S&amp;Ls) originated with 18th-  century British building societies, in which workmen banded together to  finance the building of their homes. The first U.S. savings and loan was  established in Philadelphia in 1831. S&amp;Ls were initially cooperative insti�  tutions in which savers were shareholders in the association and received  dividends in proportion to profits, but today are mutual organizations that  offer a variety of savings plans. They are not obliged to rely on individual  deposits for funds but are permitted to borrow from other financial insti�  tutions and to market mortgage-backed securities, money-market certifi�  cates, and stock.

Unlike a commercial bank, a savings bank does not accept demand  deposits. Many savings banks originated as part of a philanthropic effort to  encourage saving among people of modest means. The earliest municipal  savings banks developed from the municipal pawnshops of Italy (see pawn�  broking). Other early savings banks were founded in Germany in 1778 and  The Netherlands in 1817.

From the 11th  century the counts of Savoy ruled it as part of the kingdom of Arles under  the suzerainty of what would become the Holy Roman Empire. It became  virtually independent and expanded across the Alps to include the plain  of Piedmont in Italy. In the 18th century Piedmont and Savoy were incor�  porated into the kingdom of Sardinia, and the dukes of Savoy became  kings of Sardinia. Savoy and Piedmont were ceded to France in 1792, but  Savoy was restored to its traditional rulers in 1815, with the addition of  Genoa. In 1860 Sardinia, Genoa, and Piedmont joined other Italian states  to form the Kingdom of Italy.

His medieval successors, including Amadeus  VI, added territory in the western Alps where France, Italy, and Switzer�  land converge. In 1416 the house was raised to ducal status in the Holy  Roman Empire, after which it declined until the late 16th century.</p><p>Although under French domination in the 17th century, the house under  Victor Amadeus II acquired territory in northeastern Italy and attained the  royal title, first of the kingdom of Sicily (1713), which he exchanged for  Sardinia (1720).

It then lost its prominence,  and the monarchs Umberto I and Victor Emmanuel III served mainly as fig�  ureheads until the vote for a republic in 1946 ended Savoy rule.</p><p>saw Tool for cutting solid materials to prescribed lengths or shapes. Most  saws take the form of a thin metal strip with teeth on one edge or a thin  metal disk with teeth on the edge. The teeth are usually set to alternate  sides so that the kerf (groove) cut by the saw is wider than the thickness  of the saw; the saw blade can thus move freely in the groove without  binding. Thin-strip saws are used in various ways in both hand and  machine operations; circular, or disk, saws are always machine powered  (see SAWING MACHINE, MACHINE TOOL).</p><p>saw palmetto Any of several shrubby palms chiefly of the southern  U.S. and West Indies that have spiny-toothed petioles (leafstalks), espe�  cially a common palm ( Serenoa repens ) of the southeastern U.S., with a  usually creeping stem. Saw palmettos make up part of the vegetation  found in the Florida Everglades. When undisturbed, they grow into great  masses of foliage. The saw palmetto has recently drawn attention as the  source of a possible treatment for prostate cancer.</p><p>Sawatch \so-'wach\ Range Range of the Rocky Mountains, central  Colorado, U.S. It is 100 mi (160 km) long and is bounded by the Arkan�  sas River and the Elk Mountains. Its middle portion, with Mounts Yale,  Harvard, and Princeton, is usually called the Collegiate Range. Many  summits exceed 14,000 ft (4,300 m), including Mount Elbert (14,433 ft  [4,399 m]), the highest point in the Rockies. The discovery of gold in  1860 attracted settlers to the region. Ranching, dairying, and tourism are  the main industries today.</p><p>Sawchuk Vsow-chokV Terry in full Terrence Gordon Saw-  chuck (b. Dec. 28, 1929, Winnipeg, Man., Can.�d. May 31, 1970, New  York, N.Y., U.S.) Canadian-U.S. hockey goalie. He played two seasons in  other leagues before going to the National Hockey League (1949), in which  he played for the Detroit Red Wings (1949-54, 1957-64), Boston Bruins  (1955-56), Toronto Maple Leafs (1964-67), and other teams. His career  record of 103 shutouts still stands; he is second in career wins (447).</p><p>sawfish Any of about six species (genus Pristis, family Pristidae) of  sharklike ray. Sawfishes have a long  head, long body, and a long, toothed,  bladelike snout. The largest attain  lengths of 23 ft (7 m) or more. These  bottom-dwellers inhabit shallow  waters of subtropical and tropical  bays and estuaries and sometimes  swim up rivers. Some live in the  freshwaters of Lake Nicaragua. They  are not generally dangerous. Their  saws are used either to dig out bottom  animals or, when lashed about, to kill  or maim schooling fishes. Sawfishes  are good to eat when small; they are  fished in some areas for food, oil,  skins, and other products.</p><p>sawfiy Any of numerous, widely  distributed insect species in five  families (superfamily Tenthredi-  noidea, order Hymenoptera). Typical  sawflies (family Tenthredinidae) are  often brightly coloured and are com�  monly found on flowers; the North  American pear slug eats pear, cherry,  and plum leaves. The larvae of many  species in the other four families also  damage trees. Argid sawflies (family  Argidae) feed on rose bushes and wil�  low, oak, and birch trees.

The cutting tools (saws) may  be thin metallic disks with teeth on their edges, thin metal blades or flex�  ible bands with teeth on one edge, or thin grinding wheels. The tools may  use any of three actions: true cutting, grinding, or friction-created melt�  ing.</p><p>sawmill Machine or plant with power-driven machines for sawing logs  into rough-squared sections or into planks and boards. A sawmill may be  equipped with planing, molding, tenoning, and other machines for fin�  ishing processes. Cutting is performed on various large machines; recip�  rocating saws, band saws, or circular saws cut the log into various  thicknesses as it moves past the saw on a feeder table. The biggest mills  are usually located where timber can be brought by river or rail, and mill  design is affected by the mode of transportation.</p><p>Sax, Adolphe orig. Antoine-Joseph Sax (b. Nov. 6, 1814,  Dinant, Belg.�d. Feb. 7, 1894, Paris, France) Belgian instrument maker.  Son of an accomplished instrument maker, he worked for his father until  1842, making improvements on the clarinet and bass clarinet. He then set  up shop in Paris, supported by musicians such as Hector Berlioz and Fro-  mental Halevy (1799-1862) but opposed by French instrument makers;  he invented several new families of instruments, including the saxhorns,  the saxtrombas, and most successfully, the saxophones. A fine woodwind  player, he taught saxophone at the Paris Conservatoire (1857-71).</p><p>Saxe, (Hermann-) Maurice, count de (b. Oct. 28, 1696, Goslar,  Saxony�d. Nov. 30, 1750, Chambord, France) German-born French gen�  eral. The illegitimate son of Frederick Augustus I of Saxony, he served  under Eugene of Savoy in Flanders and was made count of Saxony (Saxe)  in 1711. He commanded a German regiment in the French service (1719)  and made innovations in military training, especially in musketry. He  served with distinction in the French army against his half brother Augus�  tus III in the War of the Polish Succession and was made a general (1734).  He successfully led French forces in the War of the Austrian Succession,  capturing Prague (1741) and invading the Austrian Netherlands. There he  won the Battle of Fontenoy (1745) and captured Brussels and Antwerp  (1746). Appointed marshal general of France by Louis XV, Saxe led the  successful invasion of Holland in 1747.</p><p>Saxe-Coburg-Gotha, House of See House of Windsor</p><p>saxifrage Vsak-s3-frij\ Any of about 300 species of the genus Saxi-  fraga, of the family Saxifragaceae, which is composed of 36 genera of  mostly perennial herbaceous plants. Members of the saxifrage family are  known for their ability to grow and thrive on exposed rocky crags and in  fissures of rocks. They are adapted to the full range of moisture condi�  tions, but most grow in moist, shaded woodlands in northern cold and  temperate regions. Leaves characteristically alternate along the stem and  sometimes are deeply lobed or form rosettes. Flowers generally are borne  in branched clusters and range in colour from greenish to white or yel�  low and from pink or red to purple. The fruit is a capsule. Saxifraga spe�  cies are planted in rock gardens or as border ornamentals, prized for their  small, bright flowers, fine-textured foliage, and early spring flowering.  Other well-known genera in the saxifrage family are Astilbe, Heuchera,  and Mitella.</p><p>Saxo Grammaticus Ysak-so-gr3- , ma-ti-k9s\ (fl. 12th century-early  13th century) Danish historian. Little is known of Saxo�s life except that  he was from Sjaelland, bom to a family of warriors, and probably served  as clerk to the archbishop of Lund. His 16-volume Gesta Danorum  (�Story of the Danes�) is the first important work on the history of Den�  mark and the first Danish contribution to world literature. A panorama of  his country�s antiquity and traditions, it inspired many 19th-century Dan�  ish Romantic poets and was the original source of the story of William  Shakespeare�s Hamlet. Saxo�s brilliant, ornate Latin earned him the name  �Grammaticus� in the 14th century.</p><p>Saxon Any member of a Germanic people who lived along the Baltic  coast in ancient times and later migrated west as far as the British Isles.  The Saxons became pirates in the North Sea during the decline of the  Roman empire, and in the early 5th century they spread through northern  Germany and along the coasts of Gaul and Britain. They fought Charle�</p><p>magne (772-804) before being incorporated into the Frankish kingdom,  and they settled Britain along with other Germanic invaders, including  the Angles and the Jutes.</p><p>Saxony German Sachsen \'zak-son\ Historical region, former state,  and recreated state, Germany. Before 1180 the name was applied to the  territory conquered c. ad 200-700 by the Germanic Saxon tribe. They  were conquered and Christianized by Charlemagne in the late 8th century.  In the mid-9th century Saxony became part of the German kingdom of  the Franks. The territory was broken up in 1180 and divided into two  smaller and widely separated areas, Saxe-Lauenburg on the lower Elbe  River and Saxe-Wittenberg on the middle Elbe. From 1422 the name Sax�  ony was applied to a large region, including the country from Thuringia  to Lusatia, bordering Bohemia. It was part of the German Empire (1871-  1918) and a free state in the Weimar Republic (1919-33). The state was  abolished in 1952 and divided among East German districts. Upon Ger�  man reunification in 1990, a new state of Saxony was recreated. The cur�  rent territory of Saxony Land (pop., 2001 est.: 4,384,192) occupies the  southeastern portion of what was formerly East Germany and covers an  area of 7,080 sq mi (18,337 sq km). The capital is Dresden.</p><p>saxophone Single-reed wind instrument with a conical metal tube and  finger keys. Though made of brass, it is classified as a woodwind instru�  ment. Its mouthpiece resembles that of the clarinet. The saxophone fam�  ily includes instruments with at least eight different ranges, the tenor and  alto instruments being the most common. The smallest (highest-range)  saxophones are straight; the rest have curved necks and their bells are  bent up and out. Transposing instruments (producing a higher or lower  pitch than indicated in music written for it) in B-flat and E-flat, all have  the same written 3V6-octave range. The saxophone was patented in 1846  by Adolphe Sax, who created two separate instrument families, for mili�  tary and orchestral use respectively. Though few composers included  saxophones in their orchestral scores, they became centrally important in  military, dance, and jazz bands.</p><p>Say \'se,\ English Ysa\, J(ean)-B(aptiste) (b. Jan. 5, 1767, Lyon,  France�d. Nov. 15, 1832, Paris) French economist. He edited a maga�  zine and started a spinning mill before joining the faculty of the Conser�  vatory of Arts and Crafts (1817-30) and the College de France (1830�  32). In his major work, A Treatise on Political Economy (1803), he  advanced his law of markets, which claims that supply creates its own  demand. He attributed economic depression not to a general deficiency in  demand but rather to temporary overproduction for some markets and  underproduction for others, an imbalance that must automatically adjust  itself as overproducers redirect their production to conform with consum�  ers� preferences. Say�s law remained a central tenet of orthodox econom�  ics until the Great Depression.</p><p>Sayan \s3-'yan\ Mountains Large upland region on the frontiers of  east-central Russia and Mongolia. The mountains form a rough arc  stretching from the Altai Mountains to Lake Baikal and connecting with  the Khamar-Daban mountain system of the Transbaikalia. The western  and eastern ranges, each with a different geologic history, meet in a cen�  tral knot where elevations exceed 10,000 ft (3,000 m). The range�s high�  est peak is Munku-Sardyk, in Mongolia, which reaches an elevation of  11,453 ft (3,491 m).</p><p>Sayers, Dorothy L(eigh) (b. June 13, 1893, Oxford, Oxfordshire,  Eng.�d. Dec. 17, 1957, Witham, Essex) English scholar and writer. In  1915 Sayers became one of the first women to graduate from Oxford Uni�  versity. Her first major work was Whose Body? (1923), in which she cre�  ated the detective Lord Peter Wimsey, a witty, dashing young gentleman-  scholar who would be featured in such later short-story collections and  novels as Strong Poison (1930), The Nine Tailors (1934), and Busman�s  Honeymoon (1937). After the 1930s she concentrated on theological dra�  mas and books, radio plays, and scholarly translations, notably of Dante�s  Divine Comedy.</p><p>Sayles, John (b. Sept. 28, 1950, Schenectady, N.Y., U.S.) U.S. film  director. He graduated from Williams College and wrote short stories and  novels, including Union Dues (1977), before becoming a screenwriter for  Roger Corman. He made his directorial debut with the acclaimed Return  of the Secaucus Seven (1980). He explored social and political issues in  other thoughtful films such as Lianna (1982), Matewan (1987), Eight Men  Out (1988), City of Hope (1991), Lone Star (1996), and Sunshine State  (2002), and he usually wrote his own screenplays.

After he became minister of foreign affairs in 1910, Sazonov promoted  close relations with Britain and France and supported the Balkan League  against Turkey. He contributed to the precipitating events of World War  I by affirming Russia�s support for Serbia against Austria and insisting  that Nicholas II order the mobilization of the Russian army (July 30, 1914);  two days later, Germany declared war on Russia. He set Russia�s war aim  as the annexation of Constantinople and the Turkish straits but was dis�  missed when he urged the tsar to grant Poland autonomy. After the Rus�  sian Revolution of 1917, Sazonov moved to France.</p><p>scabious \'ska-be-os\ Any of about 100 species of annual and peren�  nial herbaceous plants that make up  the genus Scabiosa (family Dip-  saceae), native to temperate Eurasia,  the Mediterranean, and mountains of  eastern Africa. Some are important  garden plants, including the southern  European annual pincushion flower  (S. atropurpurea), also called sweet  scabious, mourning bride, or garden  scabious. All species have leaf  rosettes at the base of the plant, and  leafy stems. Flower heads have an  outer ring of female flowers and a  circle of leaflike bracts below. Dev�  il�s bit scabious belongs to the genus  Succisa (see bluebonnet).</p><p>Scaevola Vse-vo-loV Quintus  Mucius or Pontifex (d. 82 bc)</p><p>Roman lawgiver. He served successively as consul, as governor of the  province of Asia, and from c. 89 as pontifex maximus. About 95 he  obtained the passage of the lex Licinia Mucia, removing certain groups  from the citizen rolls, which led to the Social War of 90-88. His major  work was an 80-volume systematic treatise on civil law, which was fre�  quently quoted and followed by subsequent writers. His handbook Horoi  consisted of short rules of law and explanations of legal terms; it was the  oldest work excerpted in Justinian I�s Digest.</p><p>scaffold Temporary platform used to elevate and support workers and  materials during work on a structure or machine.

Opponents  also applied the pejorative term to those who joined with carpetbaggers  and freedmen to support Republican Party policies. The term, of unknown  origin, was used from the 1840s to denote a worthless farm animal and  later a worthless person. Scalawags included former Whigs and hill-  country farmers with Unionist sympathies and constituted nearly 20% of  the white electorate after the American Civil War. Many held government  positions in the South and advocated moderate reforms.</p><p>scale In music, primary pitches of a key or mode arranged within an  octave.

He studied at Georgetown University and Harvard Law  School, where he edited its law review. Successively, he worked for a  Cleveland law firm (1961-67), taught at the University of Virginia (1967-  74), served as an assistant U.S. attorney general (1974-77), and taught at  the University of Chicago (1977-82). He was appointed by Pres. Ronald  Reagan to the U.S. Court of Appeals (1982) and then to the Supreme Court  of the United States (1986). Among the court�s most outspoken justices,  he quickly earned a reputation for aggressive oral argument and scath�  ingly critical written opinions, especially when expressing dissenting  views. An opponent of �judicial activism,� he favoured a restrained judi�  ciary, deference to the original intent of the framers in constitutional  interpretation, and a limited role for the federal government.</p><p>Scaliger Vska-b-jor\, Julius Caesar, and Scaliger, Joseph Jus�  tus (respectively b.

Julius worked in botany, zoology, and  grammar but was chiefly interested in developing an understanding and  critical evaluation of the ancients. His most widely read book was his  Poetics (1561), in which Greco-Roman rhetoric and poetics are used as a  foundation for literary criticism. His son Joseph, a precocious student of  language, studied in France, Germany, and Italy and taught in France  before he was called to the University of Leiden, where he became known  as the most erudite scholar of his time. His major works are the Study on  the Improvement of Time (1583) and Thesaurus of Time (1609), which  brought order to ancient chronology.</p><p>scallop Any of more than 400 species (family Pectinidae) of marine  bivalves found worldwide, from the intertidal zone to deep waters. The two  halves of the shell (valves) are usually fan-shaped, except for a winglike  projection at either side of the straight hinge. The shells are 1-6 in.  (2.5�15 cm) long. They may be smooth or ribbed and red, purple, orange,  yellow, or white. Cilia filter microscopic plants and animals from the  water and move them toward the mouth. Scallops swim by clapping the  valves, propelling themselves forward. The muscle that closes the valves  is a popular food item.</p><p>scalping Removal of all or part of the scalp, with hair attached, from  an enemy�s head. It is best known as a practice of North American Indian  warfare. At first confined to eastern tribes, it spread as a result of boun�  ties offered by the French, English, Dutch, and Spanish for the scalps of  enemy Indians and sometimes of enemy whites. Many American fron�  tiersmen and soldiers adopted the custom. Among Plains Indians, scalps  were taken for war honours, usually from dead enemies, although some  warriors preferred a live victim. The operation was not necessarily fatal,  and some victims were released alive.</p><p>scaly anteater See pangolin  Scamander River See Menderes River</p><p>scampi or Dublin Bay prawn or Norway lobster Edible lob�  ster ( Nephrops norvegicus), widespread in the Mediterranean and north�  eastern Atlantic.

(200 mm) long and weigh about 7 oz (200 g).  The slender claws may be almost as long as the body. Most scampi are  trawled, but some are caught in baited lobster pots.</p><p>Scandinavia Region of northern Europe, usually defined as compris�  ing Norway, Sweden, and Denmark. It is sometimes used more broadly  to include Finland and Iceland. Norway and Sweden occupy the Scandi�  navian Peninsula, though Denmark is part of the North European Plain.

It is largely mountainous; its eastern side slopes gently  to the Baltic Sea, while the western side has mountains reaching the coast  and is deeply dissected by fjords.</p><p>scanner, optical Computer input device that uses a light beam to scan  codes, text, or graphic images directly into a computer or computer sys�  tem. Bar-code scanners are used widely at point-of-sale terminals in retail  stores. A handheld scanner or bar-code pen is moved across the code, or  the code itself is moved by hand across a scanner built into a checkout  counter or other surface, and the computer stores or immediately pro�  cesses the data in the bar code. After identifying the product through its  bar code, the computer determines its price and feeds that information  into the cash register. Optical scanners are also used in fax machines and  to input graphic material directly into personal computers. See also OCR.</p><p>Scapa Flow Sea basin, Orkney Islands, Scotland. Located off of Scot�  land�s northern tip, the basin is about 15 mi (24 km) long and 8 mi (13  km) wide. Its extensive sheltered waters served as a major British naval  base during World Wars I and II. The Germans scuttled their fleet there  after World War I. The base was fortified in World War II following Ger�  man attacks and the sinking of the battleship Royal Oak in 1939. The base  closed in 1956.</p><p>scapegoat In the Old Testament, a goat that was symbolically burdened  with the sins of the people and then killed on Yom Kippur to rid Jerusalem  of its iniquities. Similar rituals were held elsewhere in the ancient world  to transfer guilt or blame. In ancient Greece, human scapegoats were  beaten and driven out of cities to mitigate calamities. In early Roman law,  an innocent person was allowed to assume the penalty of another; Chris�  tianity reflects this notion in its belief that Jesus died to atone for the sins  of mankind.</p><p>scar Mark left on the skin after a wound heals. Cells called fibroblasts  produce collagen fibres, which form bundles that make up the bulk of  scar tissue. Scars have a blood supply but no oil glands or elastic tissue,  so they can be slightly painful or itchy. Hypertrophic scars grow overly  thick and fibrous but remain within the original wound site. Scars can  also develop into tumourlike growths called keloids, which extend beyond  the wound�s limits. Both can inhibit movement when they result from  serious bums over large areas, especially around a joint. Scars, especially  those from unaided healing of third-degree bums, can become malignant.  Treatment of serious scars is one of the most important problems in plas�  tic SURGERY.</p><p>scarab \'skar-ob\ In Egyptian religion, a symbol of immortality much  used in funerary art. It was inspired  by the life cycle of the scarab beetle;  the dung balls that the beetles con�  sume, lay their eggs in, and use to  feed their young represented a cycle  of rebirth and were associated with  immortality and with the passage of  the sun across the heavens. Many  scarabs were made of precious met�  als and were worn as amulets or used  as seals. First appearing c. 2575-c.</p><p>2130 bc, they were fashioned in great  numbers during the Middle King�  dom and New Kingdom.</p><p>scarab beetle Any of about  30,000 beetle species (family Scara-  baeidae), found worldwide, that are compact, heavy-bodied, and oval.  Each antenna terminates in three flattened plates that fit together to form  a club. The outer edges of the front legs may be toothed or scalloped.  Species range from about 0.2 to 4.8 in. (5 to 120 mm) long and include  one of the heaviest known insects. One species of dung beetle, Scarabaeus  sacer , was sacred to the ancient Egyptians. Many species are agricultural  pests (e.g., chafer, Japanese beetle, June beetle); many are popular with insect  collectors because they are large and have beautifully coloured, hard,  highly polished fore wings.</p><p>Scarborough Town and borough (pop., 2001: 106,233), North York�  shire, England. Located on the North Sea coast, Scarborough originated</p><p>as a 10th-century Viking fishing settlement at the site of a 4th-century  Roman signal station. In the 12th century a Norman castle was built on  the headland. After 1626, spa development made it a fashionable resort.  It remains the most popular seaside resort in northeastern England.

He may have studied with Giacomo Carissimi in Rome.  His first known opera (1679) was a success, and by 1680 he was chapel  master in Rome for Queen Christina of Sweden. He left this secure posi�  tion to become chapel master of the viceroy of Naples (1684-1702). Most  of the operas produced in the city during this period were his own, and  they were increasingly heard in other cities as well, including Leipzig and  London. Most of his instrumental music comes from his late period, as  do his comic operas. He wrote at least 70 and perhaps more than 100  operas, as well as some 600 secular cantatas; his opera overtures ( sinfo -  nie) were important forerunners of the symphony. Domenico Scarlatti was  his son.</p><p>Scarlatti \skar-'lat-e\, (Giuseppe) Domenico (b. Oct. 26, 1685,  Naples�d. July 23, 1757, Madrid,</p><p>Spain) Italian composer and key�  board player. Son of the composer  Alessandro Scarlatti, he worked as  his father�s assistant in Naples. By  1705 he was living in Rome. His  father subsequently sent him to Ven�  ice, where he stayed until about  1708. There he probably met George  Frideric Handel and Antonio Vivaldi;  he is said to have had a contest with  Handel in which the German won at  organ playing but Scarlatti won at  the harpsichord. By 1723 he was  tutor to the Spanish infanta (later  crown princess) Maria Barbara, in  whose service he remained for much  of his life. Though he wrote operas,  oratorios, cantatas, and other works,  his reputation rests on the 555 bril�  liant one-movement keyboard sona�  tas he wrote for the princess, one of  the greatest bodies of work by any Baroque composer.</p><p>scarlet fever or scarlatina Acute infectious disease caused by some  types of streptococcus bacteria. Fever, sore throat, headache, and, in chil�  dren, vomiting are followed in two to three days by a rash. The skin peels  in about one-third of cases. After a coating disappears, the tongue is swol�  len, red, and bumpy (strawberry tongue). Glands are usually swollen.  Complications frequently involve the sinuses, ears (sometimes with mas�  toiditis), and neck. Abscesscs are common. Nephritis, arthritis, or rheumatic  fever may occur later. Treatment involves penicillin, bed rest, and adequate  fluid intake. Scarlet fever has become uncommon and much milder since  the mid-20th century, independent of the use of antibiotics.</p><p>Scarron \ska-'ro n \, Paul (baptized July 4, 1610, Paris, France�d.

(1648-53) was a very successful parody of Virgil�s Aeneid. Scarron�s  plays, often based on Spanish originals, were important in the theatrical  life of Paris.

The greater scaup, or big bluebill (A. marila), breeds across Eur�  asia and most of the Nearctic region. The lesser scaup, or little bluebill  (A. affinis ), breeds in northwestern North America. Both are popular game  birds, 15-20 in. (38-51 cm) long, that winter along the U.S. coasts. Males  have a dark breast and grayish back but differ in head colour and wing  markings; females are brown with white patches around the blue bill.  Scaups eat mainly clams. The third species is the New Zealand scaup (A.  novaeseelandiae).</p><p>Schacht \'shakt\, (Horace Greeley) Hjalmar (b. Jan. 22, 1877,  Tinglev, Ger.�d. June 4, 1970, Munich, W.Ger.) German financier. He  served as vice director of the Dresdner Bank and director of the German  National Bank before becoming a commissioner in the finance ministry  (1923), where he developed a rigorous monetary program that halted  German inflation and stabilized the mark. He became president of the  Reichsbank (1923-30, 1933-39) and minister of economics (1934-37),  but he was dismissed when he opposed Adolf Hitler�s rearmament expen�  diture. Imprisoned after the July Plot against Hitler�s life (1944), he was  later captured by the Allies and acquitted at the Nurnberg trials. He later  founded a bank in Dusseldorf and served as an international financial  consultant.</p><p>Schally Vsha-le\, Andrew V(ictor) (b. Nov. 20, 1926, Wilno, Pol.)  Polish-born U.S. endocrinologist.

An officer in the  Prussian army from 1801, he taught at the war academy and became chief  of staff in the war against Napoleon (1806). As head of the army reform  commission (from 1807), he developed the modern general staff system  and reorganized the Prussian army; with August von Gneisenau he devised  the system of rapid military training and use of army reserves. After a  forced retirement, he became chief of staff to Gebhard von BlOcher (1813)  and died of a wound received in the Battle of Liitzen.</p><p>Schaumburg-Lippe Vshaum-.burk-'li-poX Former German state.

March 30, 1654,  Halle) German composer. After study in Amsterdam with Jan Pieterszoon  Sweeunck, he returned to his native Halle and spent his entire life there in  various musical offices, including court organist and later kapellmeister  to the Margrave of Brandenburg. He wrote much sacred vocal music in  both German and Latin, including Geistliche Concerte (1631-40). His  chief work for keyboard (mostly organ) was Tabulatura nova (1624),  written in open score rather than traditional organ tablature. The collec�  tion contains fantasias, toccatas, �echo pieces,� organ responses for litur�  gical use, and, most important, variations on chorale melodies.</p><p>Schein Vshln\, Johann Hermann (b. Jan. 20, 1586, Griinhain,  Saxony�d. Nov. 19, 1630, Leipzig) German composer. After singing as  a boy in the chapel of the elector of Saxony, he studied music at the Uni�  versity of Leipzig. In 1616 he became cantor of St. Thomas Church in  Leipzig, the post later held by Johann Sebastian Bach. In this capacity, he  was an important teacher, became friends with Samuel Scheidt and Hein�  rich SchOtz, and wrote sacred works that combined the vocal lyricism of  Italian music with the Northern contrapuntal style. His Banchetto musi-  cale (1617) is a collection of dances, perhaps the first in which dances are  gathered into unified suites, with common thematic motifs. His sacred  vocal works include Opella nova (1618-26) and the hymn collection  Cantional (1627).</p><p>Schelde Vskel-do\ River or Scheldt Vskelt\ River French Escaut  \es-'ko\ River, western Europe.

May 19,  1928, Frankfurt am Main) German philosopher. He is remembered pri�  marily for his contributions to phenomenology. His Formalism in Ethics  and Non-Formal Ethics of Values (1913-16) contains a detailed critique  of the ethics of Immanuel Kant. In Man�s Place in the Universe (1928), he  advanced a rather grandiose metaphysical doctrine with affinities to  American pragmatism: humanity, God, and world are one cosmic process,  with two �poles,� spirit and �life-urge�; the ideas of spirit become real  through human life and history.</p><p>Schelling Vshel-iqV Friedrich Wilhelm Joseph von (b. Jan. 27,  1775, Leonberg, Wurttemberg�d. Aug. 20, 1854, Bad Ragaz, Switz.)  German philosopher and educator. Inspired by Immanuel Kant, in his Sys�  tem of Transcendental Idealism (1800) he attempted to unite his concept  of nature with the philosophy of Johann Gottlieb Fichte. He held that art  mediates between the natural and physical spheres when the natural (or  unconscious) and spiritual (or conscious) productions are united in artis�  tic creation. His view that the Absolute expresses itself in all beings as  the unity of the subjective and the objective was criticized by G.W.F.  Hegel. In Of Human Freedom (1809), he declared that mankind�s freedom  is real only if it is freedom for both good and evil, a position that forms  the basis of his later philosophy. A major figure of post-Kantian idealism,  Schelling had an important influence on Romanticism. See also Immanuel  Kant; Kantianism.</p><p>Schenker Vsheq-korX, Heinrich (b. June 19, 1868, Wisniowczyk,  Galicia, Russia�d. Jan. 14, 1935, Vienna, Austria) Austrian music theo�  rist. Schenker studied law and composition in Vienna before settling there  as a private teacher and occasional performer. He proposed that Jean-  Philippe Rameau�s harmonic theory had erred in making harmony funda�  mental at the expense of counterpoint. His own study of C.P.E. Bach led  him to posit counterpoint as equally fundamental and to recognize the  subtle integration of the two. Schenker�s most influential perception was  that tonal music consists of layers of ornamentation of simpler musical  statements. His controversial theories and graphic notation�presented in  texts such as Harmony (1906), Counterpoint (1910-22), and Free Com�  position (1935)�were widely disseminated in the 1970s and by the end  of the 20th century had become the basis of the most widely employed  analytical techniques for tonal music.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>scherzo &#x25BA; schistosomiasis I 1697</p><p>scherzo \'skert-,so\ Italian "joke" Musical movement in rapid triple  time; it replaced the minuet in genres such as the symphony, sonata, and  string quartet in the 19th century. The name was first used for light vocal  and instrumental pieces of the Baroque era. It formally often resembles  the minuet, being in rounded binary form and having a contrasting trio  section between two statements of the scherzo proper, but its tempo is  often much faster and its style may range from playful to vehement or  grotesque.</p><p>Schiaparelli V.skya-pa-'rel-leV Elsa (b.

After working in the U.S. as a film scriptwriter and translator, she settled  in Paris and opened her first shop in the 1920s. By 1935 she was a leader  in haute couture and was expanding into perfume, cosmetics, lingerie,  jewelry, and swimsuits. Her designs combined eccentricity with simplic�  ity and a trim neatness with flamboyant colour. She introduced the pad�  ded shoulder in 1932; designed fur bed jackets and rhinestone-trimmed  lingerie in the 1940s; and in the 1950s popularized �shortie� coats in vivid  reds, golds, and chartreuses. Her use of �shocking pink,� the sensation of  the 1947 season, is still regularly revived. With Christian Dior, she was  instrumental in the worldwide commercialization of Parisian fashion.</p><p>Schickard Vshi- I kard\ / Wilhelm (b. April 22, 1592, Herrenberg,  Wiirttemberg�d.

He proposed to Johannes Kepler the development of a  mechanical means of calculating ephemerides (predicted positions of  celestial bodies at regular intervals of time), and he contributed to the  improvement of accuracy in mapmaking.</p><p>Schiele Vshe-loV Egon (b. June 12, 1890, Tulin, Austria�d. Oct. 31,  1918, Vienna) Austrian painter, draftsman, and printmaker. He was  strongly influenced by the Jugendstil movement, and the linearity and  subtlety of his work owe much to Gustav Klimt�s decorative elegance. Still,  he always emphasized expression over decoration, heightening the emo�  tive power of line with a feverish intensity. His candid, agitated, erotic  images�often portraits of women� caused a sensation, and in 1912 he  was briefly imprisoned for indecency. His landscapes exhibit the same  febrile quality of colour and line. A special room was reserved for his  work at a Viennese exhibition in 1918, just before he died in the influ�  enza epidemic of that year. He has since been recognized as one of the  great artists of Expressionism.</p><p>Schiff VshifX, Dorothy (b. March 11, 1903, New York, N.Y., U.S.�d.  Aug. 30, 1989, New York City) U.S. newspaper publisher. Schiff was a  wealthy socialite who in 1939 used family money to buy majority con�  trol of the New York Post. In 1943 she took the title of owner and presi�  dent, and in 1962 she became editor in chief. Under her direction the Post  became a crusading liberal paper, staunchly supporting unions and social-  welfare legislation. She converted it to a tabloid format and included  popular features and columnists, with the result that in the 1960s it became  the city�s only surviving afternoon daily. In 1976 she sold the Post to  Rupert Murdoch.</p><p>Schiff, Jacob H(enry) (b. Jan. 10, 1847, Frankfurt am Main�d.

He succeeded his father-  in-law as head of the firm in 1885 and became one of the leading rail�  road bankers in the U.S. He played a pivotal role in the reorganization of  several transcontinental lines, notably the Union Pacific Railroad and the  Northern Pacific Railway. During the Russo-Japanese War he sold Japa�  nese bonds in the U.S., for which he was decorated by the emperor of  Japan. His extensive philanthropies included large contributions to Bar�  nard College and the Jewish Theological Seminary.</p><p>Schiller \'shil-3r\, (Johann Christoph) Friedrich (von) (b. Nov.  10, 1759, Marbach, Wiirttemberg�d. May 9, 1805, Weimar, Saxe-  Weimar) German dramatist, poet, and literary theorist, one of the great�  est figures in German literature. Schiller was educated at the direction of  a domineering duke, whose tyranny he eventually fled to write. With his  successful first play. The Robbers (1781), he took up the exploration of  freedom, a central theme throughout his works. Don Carlos (1787), his  first major poetic drama, helped establish blank verse as the recognized  medium of German poetic drama. His jubilant �Ode to Joy� was later used  in Ludwig van Beethoven�s Symphony No. 9. Appointed professor of his�  tory at the University of Jena in 1789, he developed his epic masterpiece,</p><p>the historical drama Wallenstein (1800). During a period spent formulat�  ing his views on aesthetic activity, he produced philosophical essays,  exquisite reflective poems, and some of his most popular ballads. He spent  his last years in ill health in Weimar, near his friend Johann Wolfgang  von Goethe. His mature plays, including Maria Stuart (performed 1800)  and Wilhelm Tell (1804), examine the inward freedom of the soul that  enables the individual to rise above physical frailties and the pressure of  material conditions.</p><p>Schinkel Vshiq-kolV Karl Friedrich (b. March 13, 1781, near Bran�  denburg, Brandenburg�d. Oct. 9, 1841, Berlin) German architect and  painter. As state architect of Prussia (from 1815), he executed many com�  missions for Frederick William III and other royal family members. He based  his work on the revival of various historical styles. His mausoleum for  Queen Louise (1810) and the brick and terra-cotta Werdersche Kirche,  Berlin (1821-30), are among the earliest Gothic Revival designs in Europe.  Other works include the Greek Revival Schauspielhaus (1818) and Altes  Museum (1822-30), both in Berlin. In 1830 Schinkel became director of  the Prussian Office of Public Works; his work as a city planner resulted  in new boulevards and squares in Berlin. His Romantic-Classical cre�  ations in architecture, landscape painting, and other related arts such as  stage sets and ironwork made him the leading arbiter of national aesthetic  taste in his lifetime.</p><p>schipperke Vski-por-ke, 'shi-por-keX Dog breed that originated in  Flanders and was used as a guard on barges. The schipperke (�little cap�  tain�) is descended from the Leauvenaar, which also gave rise to the Bel�  gian sheepdog. A short, thickset, tailless dog with a dense black coat and  a foxlike head, it stands 12-13 in. (31-33 cm) and weighs up to 18 lbs  (8 kg). It has a lively, inquisitive expression and is generally hardy and  energetic, an able vermin hunter, and a good watchdog.</p><p>Schism \'si-z3m\, Photian Controversy between Eastern and Western  Christianity in the 9th century, triggered by the opposition of the Roman  pope to the appointment of Photius as patriarch of Constantinople. Eccle�  siastical rights of jurisdiction in the Bulgarian church and a doctrinal dis�  pute over the insertion of the Filioque (�and from the Son�) clause in the  Nicene Creed were also at issue. Photius withdrew from communion with  Rome in 867; he himself was finally exiled in 886.</p><p>Schism, Western or Great Schism (1378-1417) In Roman Catho�  lic history, a period when there were two, and later three, rival popes,  each with his own College of Cardinals. The schism began soon after the  papal residence was returned to Rome from Avignon (see Avignon papacy).  Urban VI was elected amid local demands for an Italian pope, but a group  of cardinals with French sympathies elected an antipope, Clement VII,  who took up residence at Avignon. Cardinals from both sides met at Pisa  in 1409 and elected a third pope in an effort to end the schism. The rift  was not healed until the Council of Constance vacated all three seats and  elected Martin V as pope in 1417.</p><p>Schism of 1054 or East-West Schism Event that separated the  Byzantine and Roman churches. The Eastern and Western churches had  long been estranged over doctrinal issues such as the relationship of the  Holy Spirit to the Father and the Son. The Eastern church resented the  Roman enforcement of clerical celibacy and the limitation of the right of  confirmation to the bishop. There were also jurisdictional disputes  between Rome and Constantinople, including Rome�s assertion of papal  primacy. In 1054 Pope Leo IX, through his representative Humbert of Silva  Candida, and the patriarch of Constantinople, Michael Cerularius, excom�  municated each other, an event that marked the final break between the  two churches. The rift widened in subsequent centuries, and the churches  have remained separate, though the excommunications were lifted by the  papacy and the patriarch in the 20th century.

Most schists are composed largely of platy  minerals such as muscovite, chlorite, talc, biotite, and graphite. The green  colour of many schists and their formation under a certain range of tem�  perature and pressure conditions have led to distinction of the greenschist  facies in the mineral facies classification of metamorphic rocks. Schists  are usually classified on the basis of their mineralogy, with varietal names  that indicate the characteristic mineral present.</p><p>schistosomiasis V.shis-to-ss-'mI-o-sosV or bilharziasis \,bil-,har-  'zi-3-s3s\ Group of chronic disorders caused by parasitic flatworms of the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1698 I schizophrenia &#x25BA; Schlesinger</p><p>genus Schistosoma (blood flukes).

The larvae invade snails, develop to the next stage, emerge into the  water, and invade mammals to feed and breed in the bloodstream. An ini�  tial allergic reaction (inflammation, cough, late-afternoon fever, hives,  liver tenderness) and blood in the stools and urine give way to a chronic  stage, in which eggs impacted in the walls of organs cause fibrous thick�  ening (fibrosis). This condition can lead to serious liver damage in the  intestinal types and to bladder stones, fibrosis of other pelvic organs, and  urinary-tract bacterial infection.

Five main types are recognized: the paranoid, characterized by  delusions of persecution or grandeur combined with unrealistic, illogical  thinking and frequent auditory hallucinations; the disorganized (hebephre�  nic), characterized by disordered speech and behaviour and shallow or  inappropriate emotional responses; the catatonic, characterized by motor  inflexibility or stupor along with mutism, echolalia, or other speech abnor�  malities; the simple or undifferentiated type, which conforms to basic  definitions of schizophrenia but does not exhibit particular behaviours in  the aforementioned types; and the residual type, which is a chronic stage  indicating advancement toward later-stage schizophrenia. Schizophrenia  seems to occur in 0.5-1% of the general population, and more than half  of those so diagnosed will eventually recover. There is strong evidence  that genetic inheritance plays a role, but no single cause of schizophrenia  has been identified. Stressful life experiences may help trigger its onset.  Treatment consists of drug therapy and counseling.</p><p>Schlegel Vshla-golX, August Wilhelm von (b. Sept. 8, 1767, Han�  nover, Hanover�d. May 12, 1845, Bonn) German scholar and critic. He  worked as a tutor and wrote for Friedrich Schiller�s short-lived periodical  Die Horen before cofounding with his brother Friedrich von Schlegel the  periodical Athenaum (1798-1800), which became the organ of German  Romanticism. While a professor at the University of Jena, he undertook  translations of the works of William Shakespeare (1797-1810) that became  standard editions and are among the finest of all German literary trans�  lations. His Lectures on Dramatic Art and Literature (1809-11) was  widely translated and helped spread fundamental Romantic ideas through�  out Europe. From 1818 until his death he taught at the University of Bonn.</p><p>Schlegel, Friedrich von (b. March 10, 1772, Hannover, Hanover�d.  Jan. 12, 1829, Dresden, Saxony) German writer and critic. He contributed  many of his projects and theories to journals such as Athenaum (1798�  1800), the quarterly he and his brother August Wilhelm von Schlegel  founded at Jena. His study of Sanskrit led him to publish Concerning the  Language and Wisdom of India (1808), a pioneering attempt at compara�  tive Indo-European linguistics and the starting point of the study of Indo-  Aryan languages and comparative philology. His conception of a  universal, historical, and comparative literary scholarship has been pro�  foundly influential, and he is regarded as the originator of many of the  philosophical ideas that inspired early German Romanticism.</p><p>Schleicher Vshll-korV August (b.

Hegel and Charles Darwin, he formed the theory that a language is an  organism, with periods of development, maturity, and decline. He  invented a system of language classification that resembled a botanical  taxonomy, tracing groups of related languages and arranging them in a  genealogical tree. His model, the Stammbaumtheorie (�family-tree  theory�), was a major development in the study of Indo-European lan�  guages. His great work was A Compendium of the Comparative Grammar  of the Indo-European, Sanskrit, Greek and Latin Languages (1874-77),  in which he attempted to reconstruct Proto-Indo-European.</p><p>Schleicher, Kurt von (b.

His political intrigues helped  secure for him the posts of defense minister (1932) and chancellor (1932�  33). Seeking to keep the Nazis under the army�s control, he offered to  participate in a government with Adolf Hitler, but Hitler refused him and</p><p>thereafter regarded Schleicher as his  chief enemy.

The successful Darling (1965) mocked  the shallowness of the jet set, and he followed it with Far from the Mad�  ding Crowd (1967). His first American film, Midnight Cowboy (1969),  won him an Academy Award. His later films include Sunday Bloody Sun�  day (1971), Marathon Man (1976), Madame Sousatzka (1988), Cold  Comfort Farm (1995), and The Next Best Thing (2000).</p><p>Kurt von Schleicher, 1932</p><p>ARCHIV FUR KUNST UND GESCHICHTE, BERLIN</p><p>AT</p><p>Schleiden</p><p>BY COURTESY BILDARCHIV PREUSSISCHER KULTURBESITZ  BPK, WEST BERUN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Schleswig-Holstein &#x25BA; Schnabel I 1699</p><p>Schleswig-Holstein Vshlas-.vik-'hol-.shtlnN Historical area and state  (pop., 2002 est.: 2,804,249), northwestern Germany. With an area of 6,073  sq mi (15,729 sq km), the state occupies the southern half of the Jutland  Peninsula and includes Fehmam Island in the Baltic Sea and various  islands in the Frisian Islands group. Its capital is Kiel. From the 15th cen�  tury the former duchies of Schleswig and Holstein were subject to the  claims and counterclaims of Denmark, Sweden, the Holy Roman Empire,  Prussia, and Austria. The Danes ceded them to Prussia and Austria in  1864, and in 1866 both areas became part of Prussia (see Schleswig-  Holstein Question). The northern part of Schleswig was awarded to Den�  mark in 1920. The German part of Schleswig-Holstein was organized as  a state of West Germany after World War II. Industries include shipbuild�  ing, electrical engineering, paper, textiles, clothing, and tourism.</p><p>Schleswig-Holstein Question Vshles-.wig-'hol-.stlnX Conflict  between Denmark and Prussia over Schleswig-Holstein. In the 1840s the  Danish-speaking population of northern Schleswig, supported by the Dan�  ish government, wanted to detach Schleswig from Holstein and incorpo�  rate it with Denmark, whereas the German-speaking majority of the two  duchies wanted to combine them as a state within the German Confed�  eration. An 1848 uprising by Germans in the region was aided by the  Prussian army in a war that ousted Denmark�s troops (1848-51). The  agreements of 1851-52 restored the region�s status quo. In 1863 a  renewed attempt by Denmark to annex Schleswig caused Prussia and  Austria to declare war in 1864. After the Danish defeat at Dybbpl and the  occupation of Jutland, Denmark was forced to surrender all of Schleswig-  Holstein to Prussia and Austria.</p><p>Schlieffen Plan Vshle-f3n\ Plan of attack used by the German armies  at the outbreak of World War I. It was named after its developer, Count  Alfred von Schlieffen (1833-1913), former chief of the German general  staff. To meet the possibility of Germany�s facing a war against France  in the west and Russia in the east, Schlieffen proposed that, instead of  aiming the first strike against Russia, Germany should aim a rapid, deci�  sive blow with a large force at France�s flank through Belgium, then  sweep around and crush the French armies against a smaller German force  in the south. The plan used at the beginning of World War I had been  modified by Helmuth von Moltke, who reduced the size of the attacking  army and was blamed for Germany�s failure to win a quick victory.</p><p>Schliemann Vshle-manV Heinrich (b. Jan. 6, 1822, Neubukow,  Mecklenburg-Schwerin�d. Dec. 26,</p><p>1890, Naples, Italy) German archae�  ologist and excavator of Troy, Myce�  nae, and Tiryns. As a boy he loved the  Homeric poems, and he eventually  learned ancient and modem Greek  and many other languages. As a mili�  tary contractor in the Crimean War  he made a sufficient fortune to retire  at 36 and devote himself to archae�  ology. In 1873, at Hisarlik, Tur., he  discovered the remains of ancient  Troy (verifying the historical event  of the Trojan War) and a treasure of  gold jewelry (�Priam�s Treasure�),  which he smuggled out of the coun�  try. Because the Ottoman govern�  ment prevented his return, he began  excavating Mycenae in Greece,  where he found more invaluable  remains and treasures. He and Wil�  helm Dorpfeld (1853-1940)  resumed work at Hisarlik in 1878,  exposing the stratigraphy more  clearly and advancing archaeological technique. In 1884 they excavated  the great fortified site at Tiryns. Schliemann�s excavations helped to  lengthen considerably the perspective of history and to popularize archae�  ology. His contributions were genuine, though his written accounts con�  tain many self-serving fabrications.</p><p>Schlondorff Vshloen-.dorfN, Volker (b. March 31, 1939, Wiesbaden,  Ger.) German-U.S. film director. He studied filmmaking in Paris and  worked for Louis Malle and Alain Resnais. He returned to Germany to make  his first feature film, Young Torless (1968). He displayed a cool directo�  rial style that distinguished him from others in the New German cinema</p><p>movement. Forming his own production company, he made movies such  as The Lost Honor of Katharina Blum (1975) and Coup de Grace (1976).  The Tin Drum (1979) won the Golden Palm at the Cannes Film Festival  and an Academy Award for best foreign language film. His later films  include Swann in Love (1984), Voyager (1991), and The Ogre (1998).</p><p>Schmalkaldic Articles \shmal-'kal-dik\ One of the confessions of  faith of Lutheranism, written by Martin Luther in 1536 and considered by  heads of state of the Schmalkaldic League in 1537. A response to a bull  issued by Pope Paul III calling for a general council of the Roman Catho�  lic church to deal with the Reformation, the articles were prepared in order  to determine which issues could be negotiated with Roman Catholicism and  which could not be compromised. The first section discusses the unity of  God, the Holy Trinity, the Incarnation, and Jesus; on these subjects there  was no disagreement with the Catholics. The second discusses justifica�  tion by faith, the chief point of contention. The third deals with such mat�  ters as sin, repentance, the sacraments, and confession.</p><p>Schmalkaldic League \'shmal-,kal-dik\ Defensive alliance by Prot�  estant states of the Holy Roman Empire. It was established in 1531 at  Schmalkalden, Germany, to defend the newly formed Lutheran churches  from attack by the Catholic emperor Charles V. Fearing that the league  would ally itself with his enemy, Francis I of France, Charles gave it de  facto recognition until 1544, when he made peace with Francis. Charles  then moved against the league militarily and by 1547 had effectively  destroyed it. See also Schmalkaldic Articles.</p><p>Schmidt VshmitA, Helmut (b. Dec. 23, 1918, Hamburg, Ger.) German  politician, chancellor of West Germany (1974-82). A member of the  Social Democratic Party, he served in the Bundestag (1953-61, 1965-87).  He was minister of defense (1969-72) and minister of finance (1972-74)  before succeeding Willy Brandt as chancellor in 1974. A popular and  capable chancellor, he continued the policy of Ostpolitik while maintain�  ing West Germany�s key position in NATO and the European Commu�  nity. His refusal to cut West Germany�s social welfare programs prompted  the centrist Free Democrats to defect from his governing coalition. Los�  ing his majority in the Bundestag, Schmidt resigned the chancellorship  after a vote of no confidence in the Bundestag in October 1982. He was  succeeded as chancellor by Helmut Kohl.

He  soon realized the expressive poten�  tial of flat, patterned design; his  mature style, seen in Self-Portrait  with Monocle (1910), is character�  ized by boldly dissonant colours and  jagged forms. After 1911, when he  moved to Berlin, his paintings and  woodcuts showed an interest in Cub�  ism and African sculpture. Though  his works had become more conven�  tional by the 1930s, the Nazis offi�  cially declared them �degenerate.�</p><p>After World War II he taught art and  resumed painting, but his work never  regained its former power.</p><p>Schnabel Vshna-bolV, Artur (b.</p><p>April 17,1882, Lipnik, Austria�d.Aug. 15,1951, Axenstein, Switz.)

He made his debut in 1890. Based in Berlin from 1900  to 1933, he composed, taught, and gave legendary performances of the  complete sonatas of Ludwig van Beethoven and Franz Schubert for centenary  celebrations. In the 1930s he became the first to record the complete  Beethoven cycle. During the Nazi period, he moved to London, then to the  U.S. Though he mostly played works of the past, his own compositions  were ultramodern. Today he is uniquely revered by serious pianists.</p><p>Schnabel Yshna-bdlV, Julian (b. Oct. 26, 1951, New York, N.Y., U.S.)  U.S. painter.

In the 1980s he was a leading exponent of  Neo-Expressionism. His works exhibit an ambivalent emotional tone, jar�  ring colour harmonies, and a rough-hewn style; his best-known works  incorporate shards of broken plates. Though he has enjoyed considerable  success, there has been controversy regarding both the quality of his art  and his aggressive self-promotion. Starting in the 1990s, Schnabel began  to pursue film. He received widespread critical acclaim for his direction  of Before Night Falls (2000), a film about Cuban poet Reinaldo Arenas.</p><p>schnauzer Vshnaut-ssr, 'shnau-zarX Any of three German dog breeds  having a wiry black, salt-and-pepper, or black-and-tan coat.

He began musical training in Vienna and con�  tinued in Moscow, then taught at the Moscow Conservatory (1962-72).  He scored more than 60 films and was one of the first Soviet composers  to experiment with seriausm. After the death of Dmitry Shostakovich,  Schnittke became the Soviet Union�s leading composer and gained a  major international reputation as he evolved a highly eclectic style (�poly�  stylistics�). He suffered the first of several serious strokes in 1985 but  continued to compose. He wrote nine symphonies, six concerti grossi,  many concertos, four string quartets, and the operas Life with an Idiot  (1992), Gesualdo (1995), and Historia von D. Johann Fausten (1995).</p><p>Schnitzler X'shnits-brX, Arthur (b. May 15, 1862, Vienna, Austria�d.  Oct. 21, 1931, Vienna) Austrian playwright and novelist. Schnitzler prac�  ticed medicine in Vienna most of his life, and he also studied psychiatry.  He became known for his psychological dramas and for his fearlessness  in depicting the erotic lives of his characters, beginning with the early  play Anatol (1893). His best-known play, Reigen ( Merry-Go-Round ,  1897), was a cycle of 10 dramatic dialogues that traced the links con�  necting the partners in a series of sexual encounters; considered scandal�  ous when first performed in 1920, it was filmed as La Ronde by Max  OphQls in 1950. His drama Playing with Love (1896) and his most suc�  cessful novel. None but the Brave (1901), revealed the hollowness of the  Austrian military code of honour.</p><p>Schoenberg Vshoen-.berkA English X'sharn-.bargX, Arnold (Franz  Walter) (b. Sept. 13, 1874, Vienna,</p><p>Austro-Hungarian Empire�d. July  13, 1951, Los Angeles, Calif., U.S.)</p><p>Austrian-born U.S. composer. He  was raised as a Catholic by his  Jewish-bom parents. He began  studying violin at age eight and later  taught himself cello. While working  as a bank clerk, he studied composi�  tion with Alexander Zemlinsky  (1871-1942); Schoenberg soon  wrote his first string quartet (1897),  which was acclaimed. With Richard  Strauss�s help he obtained a teaching  post in Berlin, but he soon returned  to Vienna, having composed his  gigantic cantata Gurrelieder (1901,  orchestrated 1913). In 1904 Alban  Berg and Anton Webern began their  studies with him, which would pro�  foundly shape their later artistic  careers. About 1906 Schoenberg  came to believe that tonality had to be abandoned. During his subsequent  period of �free atonauty� (1907-16) he created remarkable works such as  the monodrama Erwartung (1909), Five Orchestral Pieces (1909), and  Pierrot lunaire (1912). From 1916 to 1923 he issued almost nothing, being  occupied with teaching and conducting but also seeking a way to orga�  nize atonality. He eventually developed the 12-tone method (see serial-  ism), in which each composition is formed from a special row or series of  12 different tones. In 1930 he began work on a three-act opera based on</p><p>a single tone row; Moses undAron remained unfinished at his death. The  rise of Nazism moved him to reassert his Jewish faith and forced him to  flee to the U.S., where he remained, teaching at the University of Cali�  fornia at Los Angeles (1936-44). Though never embraced by a broad  public, he may have exercised a greater influence on 20th-century music  than any other composer.</p><p>Scholasticism Theological and philosophical movement, beginning in  the 11th century, that sought to integrate the secular understanding of the  ancient world, as exemplified by Aristotle, with the dogma implicit in the  revelations of Christianity. Its aim was a synthesis of learning in which  theology surmounted the hierarchy of knowledge. Principal figures in  early Scholasticism were Peter Abelard, St. Anselm of Canterbury, St. Alber-  tus Magnus, and Roger Bacon. The movement flourished in the 13th cen�  tury, drawing on the writings and doctrines of St. Thomas Aquinas. By the  14th century Scholasticism was in decline, but it had laid the foundations  for many revivals and revisitations in later centuries, particularly under  Pope Leo XIII (1879), who sought to modernize the insights of the medi�  eval scholastics. Modem philosophers influenced by Scholasticism  include Jacques Maritain and Etienne Gilson (1884-1978).</p><p>Schonerer X'shoe-no-rarX, Georg, knight von (b. July 17, 1842,  Vienna, Austria�d.

He became an ardent German nationalist and outspoken  anti-Semite and in 1885 founded the Pan-German Party. Reelected to the  parliament in 1897, he opposed the pro-Czech language ordinances and  was credited with driving the prime minister from office. He helped 21  Pan-German candidates win election to the parliament in 1901. His vio�  lent temperament so disrupted the party that by 1907 it had virtually dis�  appeared from Austrian politics, but his ideological influence continued  undiminished.</p><p>Schongauer X'shon-.gau-orX, Martin (b. 1445/50, Colmar, Alsace�d.

His engravings,  consisting of about 115 plates, represent a highly refined manifestation of  the late Gothic spirit. He brought engraving to maturity by expanding its  range of contrasts and textures, bringing an artist�s sensibility to an art  hitherto the domain of goldsmiths. The grace of his work became pro�  verbial in his lifetime, giving rise to such nicknames as Hiibsch (�Charm�  ing�) Martin and Schon (�Beautiful�) Martin.</p><p>school psychology Branch of applied psychology that deals largely  with educational assessment, psychological testing, and student consulta�  tion in elementary and secondary schools.

He served as topographer on an expedition to the Lake Superior  region (1820), then married a woman who was part Ojibwa and became  an Indian agent. In 1832 he discovered the source of the Mississippi River  at Lake Itaska, Minn. A treaty he concluded with the Ojibwa in 1836 ceded  much of their land in northern Michigan to the U.S. Schoolcraft�s six-  volume Indian Tribes of the United States (1851-57) was a pioneering,  though flawed, work.</p><p>schooling behaviour Activity characteristic of clupeiform fish (her�  rings, anchovies, and allies) in which many fish swim together, appearing  to act as a single organism. A school of herring may contain many mil�  lions of individuals of roughly similar size. Fishes above or below the  size limit break away and form schools among themselves. The primary  advantage to the fish seems to be safety for the individual. When threat�  ened, a school of thousands of anchovies, spread over several hundred  metres, will contract to a writhing sphere only a few metres across,  thereby thwarting the attempt of a natural predator to catch a single indi�  vidual.</p><p>schooner X'skti-norX Sailing ship rigged with fore-and-aft sails on its  two or more masts.

He regarded the  Upanishads, together with the works  of Plato and Immanuel Kant, as the  foundation of his philosophical sys�  tem, a metaphysical doctrine of the  will developed in reaction to the ide�  alism of G.W.F. Hegel. His magnum  opus, The World as Will and Repre�  sentation (1819), consists of two  comprehensive series of reflections  on the theory of knowledge and the  philosophy of nature, aesthetics, and  ethics. By turning away from spirit  and reason to the powers of intuition,  creativity, and the irrational, he influ�  enced (partly via Friedrich Nietzsche)  the ideas and methods of vitalism,  life philosophy, existentialism, and  anthropology. His other works include On the Will in Nature (1836), The  Two Main Problems of Ethics (1841), and Parerga and Paralipomena  (1851).

A member of the SPD, he served in the Bundestag (1980-86) and  in 1990 succeeded to the premiership of the state of Lower Saxony. His  election as federal chancellor in 1998 ended 16 years of conservative rule  under Helmut Kohl. Despite continuing high unemployment in Germany,  Schroder led his Social Democratic-Green coalition to victory in 2002,  and he was reelected chancellor. As the country�s economy worsened, he  introduced in 2003 a major reform program that proved highly unpopu�  lar, and the following year he stepped down as SDP leader.

It  relates kinetic energy and potential energy to the total energy, and it is solved  to find the different energy levels of the system. Schrodinger applied the  equation to the hydrogen atom and predicted many of its properties with  remarkable accuracy. The equation is used extensively in atomic, nuclear,  and solid-state physics.

He  learned violin from his schoolteacher father and piano from his brother.  He joined the precursor of the Vienna Boys Choir (1808), making such  quick progress that Antonio Salieri undertook to guide his training (1810�  16). At his family�s insistence, he was trained as a schoolteacher. In 1815  he wrote 2 symphonies, more than 100 songs, and 4 stage works. In 1818,  seeking independence, he quit teaching at his father�s school to tutor  Johann Esterhazy�s daughters. In 1819-20 he wrote the celebrated Trout  Quintet and a mass. In 1821, 20 of his most popular songs were published  with great success, and he wrote the three-act opera Alfonso und Estrella.  Despite his first awareness of the disease (possibly syphilis) that would  kill him, his amazing production continued in 1822, with the Unfinished  Symphony and the Wanderer Fantasy. He was often ill during his last five  years but continued his production of music, including the song cycles  The Miller�s Beautiful Daughter and Winter Journey, the last three piano  sonatas, and the Great Symphony. His last years were made miserable by  illness, not poverty; in fact, his greatness was widely recognized. He died  at 31, having produced more masterpieces by that age than almost any  other composer in history. His 600 songs made the lied a serious genre  and sparked its great development in subsequent decades.</p><p>Schuller Vshul-orV Gunther (Alexander) (b.

During World War II he worked  on theories for full-employment policies and, under William H. Beveridge,  plans for Britain�s postwar welfare state. Between 1950 and 1970 he was  an adviser to Britain�s nationalized coal industry. After a visit to Burma  in 1955, he came to believe that poor countries needed an �intermediate  technology� adapted to the unique needs of each in order to develop. In  the influential Small Is Beautiful (1973) he argued that capitalism brought  higher living standards at the cost of deteriorating culture and that  bigness�especially large industries and large cities�was unaffordable.</p><p>Schuman Vshu-.manX, Robert (b.

After working in the French Resis�  tance in World War II, he helped found the Popular Republican Movement.  He served as finance minister (1946), premier (1947�48), foreign minis�  ter (1948-52), and minister of justice (1955-56). In 1950 he proposed the  Schuman Plan to promote European economic and military unity, which  led to the European Coal and Steel Community and the European Economic  Community (EEC).

Trained by her  father, the noted piano teacher  Friedrich Wieck (1785-1873), she  debuted as a prodigy with Leipzig�s  Gewandhaus Orchestra in 1830, and  then she toured for two years. By  1835 she had fallen in love with Rob�  ert Schumann, the Wiecks� boarder  since 1830. When Clara turned 21  years old, they eloped against her  father�s wishes. Her artistic stature  had already been established by her  tours, but the birth of eight children  limited her career, and she stopped  writing music in 1853 after showing  considerable promise as a composer.</p><p>Robert�s mental deterioration led to  her resuming touring full-time; she  retired from performing and teaching  in the 1890s because of ill health.</p><p>From 1853 she had a close lifelong relationship with Johannes Brahms.</p><p>Schumann, Robert (Alexander) (b. June 8, 1810, Zwickau,  Saxony�d. July 29, 1856, Endenich, near Bonn, Prussia) German com�  poser. Son of a bookseller, he considered becoming a novelist. Under  family pressure he reluctantly entered law school, but he devoted his time  to song composition and piano lessons. An injury to one of his fingers put  an end to his hopes of a career as a virtuoso and confined him to com�  position. He embarked upon a prolific period, writing piano pieces and  founding, in 1834, the New Journal for Music. His works from this fer�  tile period include Papillons, Carnaval (both 1833-35), and Davidsbiin-</p><p>dlertanze (1837). He married the pianist Clara Wieck in 1840. That year  he returned to the field of the solo song; in the span of 11 months he  composed nearly all the songs on which much of his reputation rests, such  as the song cycles Dichterliebe and Frauenliebe und Leben. The next year  he widened his scope to orchestral music, producing Symphony No. 1,  Symphony No. 4 , and his piano concerto; in 1842 he concentrated on  chamber music. In his last productive years, he turned to dramatic or  semidramatic works. His mental deterioration (probably associated with  both syphilis and a family history of mental illness) accelerated; in 1854  he was placed in a sanatorium, where he died two years later.</p><p>Schumpeter Vshum-.pa-torV Joseph A(lois) (b.

Educated in Austria, he taught at several Euro�  pean universities before joining the faculty of Harvard University (1932�  50). He became known for his theories of capitalist development and the  business cycle. His popular book Capitalism, Socialism, and Democracy  (1942) argued that capitalism would eventually perish of its own success.

Elected to  the Austrian parliament in 1927, he served in the government of Engelbert  Dollfuss as minister of justice (1932) and education (1933-34). After Doll-  fuss was assassinated, Schuschnigg was named chancellor. He disbanded  the paramilitary Heimwehr in 1936 and tried to prevent the German take�  over of Austria. After making concessions to Adolf Hitler in February 1938,  he sought to reassert national independence through a plebiscite to be held  on March 13. However, on March 11 Germany invaded Austria and carried  out the Anschluss, and Schuschnigg was imprisoned until the war ended.

He  emigrated to the U.S. in 1939, teaching at the New School for Social  Research in New York (1943-59). He drew attention to the social pre�  suppositions underlying everyday life and to the creation of social reality  through symbols and human action. His work laid the basis for the field  of ethnomethodology, the study of people�s commonsense understandings  of the structure of social interaction.

He served in the New York legislature (1768-75)  and in the Continental Congress (1775-77, 1778-80). In the American  Revolution he was commissioned one of four major generals in the Con�  tinental Army. As commander of the northern department, he was unable,  because of illness, to undertake his planned invasion of Canada.

In 1892 Car�  negie delegated to Schwab the task of returning the plant in Homestead,  Pa., to normal production after the bloody Homestead Strike. His success  in improving labour relations and increasing production led to his appoint�  ment as president of Carnegie Steel Co. in 1897 at the age of 35. Schwab  proposed the merger of the competing steel companies that would create  the U.S. Steel Corp., and he became its first president in 1901. He resigned  in 1903 to devote himself to the Bethlehem Steel Corp., which he built into  one of the nation�s largest steel producers of its time.</p><p>Schwann \'shvan\, Theodor (b.

A year  after Mathias Jacob Schleiden, a colleague Schwann knew well, advanced  the cell theory for plants, Schwann extended it to animals. While inves�  tigating digestive processes, he isolated a substance responsible for diges�  tion in the stomach, the first enzyme prepared from animal tissue, and  named it pepsin. He studied muscle contraction and nerve structure, dis�  covering the striated muscle in the upper esophagus and the myelin sheath  covering nerve cells. He coined the term metabolism, identified the role  played by microorganisms in the decomposition of organic matter, and  formulated the basic principles of embryology by observing that the egg  is a single cell that eventually develops into a complete organism.</p><p>Schwartz, Arthur See Howard Dietz</p><p>Schwartz Vshworts\, Delmore (b.

In 1901 he became  professor and director of the observatory at the University of Gottingen.  He gave the first exact solution of Albert Einstein�s general equations of  gravitation, which led to a description of how mass curves space. He also  laid the foundation of the theory of black holes, using the gravitational  equations to show that a body of sufficient mass would have an escape  velocity greater than the speed of light and therefore would not be directly  observable, since even light rays from it could not escape into space. See  also Schwarzschild radius.</p><p>Schwarzschild radius or gravitational radius Radius inside  which the gravitational attraction between a body�s particles must cause  its irreversible gravitational collapse, named for Karl Schwarzschild. This  is thought to be the final fate of the most massive stars (see black hole).  The gravitational radius ( R g ) of an object of mass M is given by R =  2 GM/c 2 , where G is the universal gravitational constant and c the speed  of light. For a star like the Sun, the Schwarzschild radius would be about  1.8 mi (3 km).</p><p>Schweitzer \'shwlt-s9r\, Albert (b. Jan. 14, 1875, Kaysersberg, Upper  Alsace, Ger.�d.

In his  early years he obtained a degree in  philosophy (1899) and became an  accomplished organist. In his biog�  raphy of Johann Sebastian Bach (2  vol., 1905), he viewed Bach as a reli�  gious mystic. He also wrote on organ  construction and produced an edition  of Bach�s organ works. His books on  religion include several on St. Paul;  his Quest of the Historical Jesus  (1910) became widely influential. In  1905 he announced he would  become a mission doctor and devote  himself to philanthropic work. He  and his wife moved in 1913 to Lam-  barene in French Equatorial Africa (now Gabon) and with locals built a  hospital on the banks of the Ogooue River, to which they later added a</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1704 I Schwitters &#x25BA; Scipio Africanus</p><p>leper colony.

It often  begins after lower back strain and is  associated with spinal disk herniation. Pain is increased by coughing,  sneezing, or bending the neck forward. Muscle relaxants, painkillers, and  nerve stimulation are among the treatments, but surgery to relieve pres�  sure on the nerve is needed if pain is disabling or nerve function is pro�  gressively disturbed (with leg weakness and loss of feeling).

Historically, it has had two main preoccupations, ontological and  epistemological. The ontological preoccupations (which frequently over�  lap with the sciences themselves) ask what kinds of entities can properly  figure in scientific theories and what sort of existence such entities pos�  sess. Epistemologically, philosophers of science have analyzed and evalu�  ated the concepts and methods employed in studying natural phenomena,  both the general concepts and methods common to all scientific inquiries  and the specific ones that distinguish special sciences.</p><p>science fiction Fiction dealing principally with the impact of actual or  imagined science on society or individuals, or more generally, literary  fantasy including a scientific factor as an essential orienting component.  Precursors of the genre include Mary Shelley�s Frankenstein (1818), Rob�  ert Louis Stevenson�s The Strange Case of Dr. Jekyll and Mr. Hyde (1886),  and Jonathan Swift�s Gulliver�s Travels (1726). From its beginnings in  the works of Jules Verne and H.G. Wells, it emerged as a self-conscious  genre in the pulp magazine Amazing Stories, founded in 1926. It came  into its own as serious fiction in the magazine Astounding Science Fic�  tion in the late 1930s and in works by such writers as Isaac Asimov, Arthur  C. Clarke, and Robert Heinlein. A great boom in popularity followed World  War II, when numerous writers� approaches included predictions of future  societies on Earth, analyses of the consequences of interstellar travel, and  imaginative explorations of intelligent life in other worlds. Much recent  fiction has been written in the �cyberpunk� genre, which deals with the  effects of computers and artificial intelligence on anarchic future societ�  ies. Radio, film, and television have reinforced the popularity of the genre.</p><p>Scientific American U.S. monthly magazine interpreting scientific  developments to lay readers. It was founded in 1845 as a newspaper  describing new inventions. By 1853 its circulation had reached 30,000  and it was reporting on various sciences, such as astronomy and medi�  cine, apart from inventions. In 1921 it became a monthly. From its found�</p><p>ing it used woodcut illustrations, and it was one of the first papers to use  halftone illustrations. Its articles�solidly based on scholarly research,  well written, carefully edited, and accompanied by definitions of scien�  tific terms and by illustrations�have made it the most highly regarded  magazine of its genre.</p><p>scientific method Mathematical and experimental techniques  employed in the natural sciences. Many empirical sciences, especially the  social sciences, use mathematical tools borrowed from probability theory  and statistics, together with such outgrowths of these as decision theory,  game theory, utility theory, and operations research.

He was bom into a patri�  cian family that had produced several consuls. As a military tribune, he  fought at the Battle of Cannae (216), managing to escape from the defeat.  While still young, he secured Spain for Rome by 206, driving the  Carthaginians out and avenging his father�s death. As consul in 205 he  was granted permission to attack the Carthaginians in Africa. In 202 he  was victorious over Hannibal at the Battle of Zama, ending the Second  Punic War and winning the name Africanus. His political opponents, led  by Cato, accused Scipio and his brother Lucius of offering too lenient  terms to Macedonia after their engagement there and of not being able to  account for money supposedly received in those terms.

He first distinguished himself in the Third Macedonian  War (168). He then campaigned in Spain and went on to Africa (150),  where he displayed great military skill against Carthage while serving as  military tribune, and demand arose that he take the command against  Carthage. Though under age, he was elected consul in 147 and returned  to Africa. He besieged and destroyed Carthage (146), ending the Third  Punic War and establishing the province of Africa. Again made consul in  134, he was given command of the Celtiberian War (see Celtiberia), and  he secured Spain by besieging and destroying Numantia (133). Back in  Rome, he took an unpopular position on a bill supported by his friend  Tiberius Gracchus; he was due to speak on the question when he died  unexpectedly.</p><p>Picture with Light Centre, collage of  paper with oil on cardboard by Kurt  Schwitters, 1919; in the Museum of  Modern Art, New York City.</p><p>COURTESY OF THE MUSEUM OF MODERN ART, NEW YORK</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>scirocco &#x25BA; scoter I 1705</p><p>scirocco See sirocco</p><p>scissors Cutting instrument or tool consisting of a pair of opposed metal  blades that meet and cut when the handles at their ends are brought  together.

Jan. 21, 1922, Hurstpierpoint, Sussex,  Eng.) British actor. After entertaining the troops in World War II, he joined  the theatre company at Stratford-upon-Avon (later the Royal Shakespeare  Company) in 1946, winning acclaim as Henry V and Hamlet. He had his  greatest success in A Man for All Seasons in London (1960) and New  York City (1961-62) and reprised the role on film (1966, Academy  Award). He continued to excel in stage productions, notably Uncle Vanya  (1970) and Amadeus (1979). He appeared in the film versions of King  Lear (1971), A Delicate Balance (1973), and Henry V (1989), and he later  acted in the films Quiz Show (1994) and The Crucible (1996).</p><p>Scone VskiinV, Stone of Rectangular block of yellow sandstone deco�  rated with a Celtic cross, which has been associated with the crowning  of Scottish kings since medieval times. Legend says it was Jacob�s pil�  low in the Holy Land, and it was taken to Ireland and then carried off by  invading Scots. Kenneth I MacAlpin brought it to the Scottish village of  Scone c. 840. Edward I took it to England (1296), where it was later placed  under the Coronation Chair in Westminster Abbey as a symbol of the  authority of English kings over Scotland. It was finally returned to Scot�  land in 1996.</p><p>Scopas or Skopas Vsk6-pos\ (fl. 4th century bc, Greece) Greek sculp�  tor and architect. Ancient writers ranked him with Praxiteles and Lysippus  as one of the major sculptors of the late Classical period. He helped  establish the expression of powerful emotions as an artistic theme. He  apparently worked on three monuments: the temple of Athena Alea at  Tegea, the temple of Artemis at Ephesus, and the Mausoleum at Halicar�  nassus. Of many freestanding sculptures attributed to him, the Maenad in  Dresden and the Pothos in Rome are the most noteworthy.</p><p>Scopes Trial (July 10-21, 1925) Widely publicized trial (called the  �Monkey Trial�) in Dayton, Tenn. John T. Scopes (1900-70), a high-  school teacher, was charged with teaching Charles Darwin�s theory of  evolution, which violated a state law prohibiting the teaching of any doc�  trine that denied the divine creation of humans. The trial was broadcast  live on radio and attracted worldwide interest. The prosecutor was Wil�  liam Jennings Bryan; the defense attorney was Clarence Darrow. The judge  limited arguments to the basic charge to avoid a test of the law�s consti�  tutionality and a discussion of Darwin�s theory. Scopes was found guilty  and fined $100; he was later acquitted on the technicality that he had been  fined excessively. The law was repealed in 1967.</p><p>score In music, the parts of all the instruments or singers of an ensemble  notated with simultaneous sounds aligned vertically, on a system of par�  allel staffs arranged one above another. Polyphonic (multivoiced) music  was being composed for some 600 years before the score came into regu�  lar use in the 16th-17th centuries. Early examples of scores exist for  works of the Notre-Dame school, and early composers may have used  temporary scores during composition, perhaps on chalkboards, from  which the parts for individual singers were then copied.</p><p>Scorel Vskor-oL, Jan van (b. August 1495, Schoorel, Habsburg  Netherlands�d. Dec. 6, 1562, Utrecht) Dutch humanist, architect, engi�  neer, and painter. He studied briefly with Jan Gossart, who encouraged</p></section><section><p>him to travel. Five years of work and study in Europe eventually took  him to Rome. Returning to Holland in 1524, he introduced such Italian  Renaissance elements as nudes, Classical draperies and architecture, and  spacious imaginary landscapes. His greatest works are his portraits, which  show his gift for characterization. He successfully combined the idealism  of Renaissance Italy with the naturalism of northern European art in his  paintings, and he bequeathed the style to successive generations of Dutch  artists.</p><p>Scoresby Sound \'skorz-be\ Deep inlet, Norwegian Sea, eastern cen�  tral coast of Greenland.

Foamlike scoria, in which the bubbles are very thin  shells of solidified basaltic magma, occurs as a product of explosive erup�  tions (as on Hawaii) and as frothy crusts on some lavas. Other scoria,  sometimes called volcanic cinder, resembles clinkers, or cinders from a  coal furnace.</p><p>Scorpio or Scorpius Latin "Scorpion'' In astronomy, the constel�  lation lying between Libra and Sagittarius; in astrology, the eighth sign  of the zodiac, governing approximately the period October 24-November  21. Its symbol, a scorpion, refers to the Greek myth of the scorpion that  stung Orion. The story explains why the constellation of Orion sets as  Scorpius rises in the sky. Another Greek myth says that a scorpion caused  the horses of the sun to bolt when they were being driven by the inex�  perienced Phaethon.</p><p>scorpion Any of some 1,300 nocturnal arachnid species (order Scorpi-  onida, subphylum Chelicerata) having a slender body, a segmented tail  tipped with a venomous stinger, and six pairs of appendages. The small  first pair tear apart insect and spider prey. Strong, clawlike pincers on the  large second pair, held horizontally in front, are used as feelers and for  grasping prey while sucking the tissue fluids. The last four pairs, each  with a pincer, are walking legs. The venom is either a hemotoxin that, in  humans, causes swelling, redness, and pain or a neurotoxin that may cause  convulsions, paralysis, cardiac irregularities, and death. Most scorpions  will sting a human only if provoked. Nocturnal hunters, most species are  tropical or subtropical.</p><p>scorpion fish Any of the numerous species of carnivorous marine fish  of the family Scorpaenidae, espe�  cially those in the genus Scorpaena,  widely distributed in temperate and  tropical waters.

Capital: Edinburgh. The  population is a blend of Celtic, Angle, and Norman ancestry. Languages:  English (official), Scottish Gaelic, and Scots. Religion: Church of Scotland  (Presbyterian; official). Currency: pound sterling. Scotland has three major  geographic regions. The Highlands, in the north, are occupied by a series of  lakes and the Grampian Mountains. The Lowlands, which include some of  Scotland�s best farmland, comprise the other two major regions: the Mid�  land Valley (Central Lowlands) and the Southern Uplands; the Southern  Uplands feature narrow, flat valleys separating table mountains. Scotland  has a temperate oceanic climate. Important industries are coal and oil pro�  duction, electronics, forestry, and marine fishing. Picts inhabited the region  when it was invaded by the Romans c. ad 80. In the 5th century it split into  four kingdoms under the Picts, Scots, Britons, and Angles. Scottish unifi�  cation began in the 9th century. It came under a heavy Anglicizing influ�  ence from the 11th century, and its ruler was forced to pay homage to the  English crown in 1174, leading to numerous future disputes. The Scottish  and English kingdoms were united in 1603 when James VI, son of Mary,  Queen of Scots, ascended the English throne as James I. Scotland became  part of the United Kingdom of Great Britain in 1707, when the parliaments  of both governments passed the Act of Union. The English prevailed in two  Scottish rebellions in the 18th century, and after 1745 the history of Scot�  land became part of the history of Great Britain. Scotland has no sovereign  executive but retains vestiges of ancient sovereignty in its own legal and  educational systems. In 1997 the Scots passed a referendum that allowed  them to establish their own parliament in Edinburgh to vote on wide-  ranging political issues while remaining part of the United Kingdom. The  Scottish Parliament first convened in 1999.</p><p>Scotland Yard officially New Scotland Yard Headquarters of the  London Metropolitan Police, and, by extension, the force itself. The Lon�  don police force was created in 1829 by Sir Robert Peel and housed at 4  Whitehall Place, which had an entrance in Great Scotland Yard. In 1890  it moved to a new building; that location became New Scotland Yard, a  name that was kept when it moved again in 1967. In addition to duties  common to all metropolitan police forces (including crime detection and  prevention and traffic management), it is entrusted with civil defense in  times of emergency, and it maintains a special branch for guarding vis�  iting dignitaries, royalty, and political dignitaries. It keeps records on all  known criminals in Britain, and other British police forces often seek its  assistance. It also helps train the police of Commonwealth nations.</p><p>Scott, George C(ampbell) (b. Oct. 18, 1927, Wise, Va., U.S.�d.  Sept. 22, 1999, Westlake Village, Calif.) U.S. actor. He served in the U.S.  Marines before studying drama and journalism at the University of Mis�  souri. He took numerous roles in television and repertory theatre produc�  tions before winning praise for his early film roles in Anatomy of a Murder  (1959), The Hustler (1961), and Petulia (1968). He was noted for his  strong screen presence and barking voice. He won an Academy Award for  Patton (1970) but refused to accept it, calling the competition a �meat  parade.� Among his later films were The Hospital (1972), Hardcore  (1979), Taps (1981), and Malice (1993). His television work included The  Price (1970, Emmy Award, also refused) and the role of Scrooge in A  Christmas Carol (1984).</p><p>Scott, Paul (Mark) (b. March 25, 1920, Palmers Green, Eng.�d.  March 1, 1978, London) British novelist. Scott entered military service  in India in the 1940s and later was a director of a London literary agency;  he resigned in 1960 to write full-time. He is known for works chronicling  the decline of the British occupation of India, notably The Raj Quartet �  consisting of The Jewel in the Crown (1966), The Day of the Scorpion  (1968), The Towers of Silence (1971), and A Division of the Spoils  (1975)�and Staying On (1977, Booker Prize). All his works, including  those set outside India, employ Indian themes or characters.</p><p>Scott, Sir Peter Markham (b. Sept. 14, 1909, London, Eng.�d.

In 1946 he founded the Severn Wildfowl  Trust (later renamed the Wildfowl and Wetlands Trust). Through a cap�  tive breeding program at his sanctuary, he saved the nene from extinction  in the 1950s. In 1961 he founded the World Wildlife Fund (World Wide</p><p>Fund for Nature). As a member of the Species Survival Commission of  the International Union for Conservation of Nature and Natural Resources  (1962-81), he created the Red Data Book (see endangered species). He was  knighted in 1973.</p><p>Scott, Ridley (b. Nov. 30, 1937, South Shields, Durham, Eng.) British  film director. He studied art and worked as a set designer and director in  British television, then formed his own production company in 1967 to  make television commercials. His first feature film was The Duellists  (1977). It was followed by the science-fiction thrillers Alien (1979) and  Blade Runner (1982), a box-office hit that became a cult classic for its  vividly dark images. His later films include Someone to Watch over Me  (1987), Thelma &amp; Louise (1991), and Gladiator (2000), which won the  Academy Award for best picture.</p><p>Scott, Robert Falcon (b. June 6, 1868, Devonport, Devon, Eng.�d.  c. March 29, 1912, Antarctica) British explorer. He joined the Royal Navy  in 1880, proved his competence leading an Antarctic expedition (1901�  04), and was promoted to captain. In 1910 he embarked on a second  expedition, and in October 1911 he and 11 others started overland for the  South Pole. After their motor sledges broke down and seven men returned  to base camp, Scott and four others trekked for 81 days to reach the pole  in January 1912, only to find that Roald Amundsen had preceded them by  about a month. Exhausted and beset by bad weather and insufficient sup�  plies, the men died on the return trip, Scott and the last two survivors only  11 miles from their base camp. In England Scott was celebrated as a  national hero for his courage, though his judgment has been questioned.</p><p>Scott, Sir Walter, 1st Baronet (b. Aug. 15, 1771, Edinburgh,  Scot.�d. Sept. 21, 1832, Abbots�  ford, Roxburgh) Scottish writer,  often considered both the inventor  and the greatest practitioner of the  historical novel. From childhood  Scott was familiar with stories of the  Border region of Scotland. Appren�  ticed to his father, a lawyer, in 1786,  he later became sheriff depute of Sel�  kirk and clerk to the Court of Session  in Edinburgh. His interest in border  ballads led to the collection Min�  strelsy of the Scottish Border (1802-  03). His first original poetic romance,</p><p>The Lay of the Last Minstrel (1805),  established his reputation; The Lady  of the Lake (1810) was his most suc�  cessful contribution to the genre. He  produced editions of the works of  John Dryden, 18 vol. (1808), and  Jonathan Swift, 19 vol. (1814).</p><p>Troubled with debt, from 1813 he  wrote in part to make money. He tired  of narrative poetry and turned to  prose romances. The extremely  popular series now known as the  Waverley novels consists of more than two dozen works dealing with Scot�  tish history, including the masterpieces Old Mortality (1816), Rob Roy  (1817), and The Heart of Midlothian (1818). He drew on English history  and other themes for Ivanhoe (1819), Kenilworth (1821), and Quentin Dur-  ward (1823). All his novels were published anonymously until 1827.</p><p>Scott, Winfield (b. June 13, 1786, Petersburg, Va., U.S.�d. May 29,  1866, West Point, N.Y.) U.S. army officer. He fought in the War of 1812  at the battles of Chippewa and Lundy�s Lane (1814). Promoted to major  general, he traveled to Europe to study military tactics. He advocated a  well-trained and disciplined army, earning the nickname �Old Fuss and  Feathers� for his emphasis on military formalities. In 1841 he became  commanding general of the U.S. Army. He directed operations during the  Mexican War and led the U.S. invasion at Veracruz and the victory at the  Battle of Cerro Gordo. He was the Whig Party�s nominee in the 1852  presidential election but lost to Franklin Pierce. In 1855 he was promoted  to lieutenant general, becoming the first man since George Washington to  hold that rank. Scott was still commander in chief of the U.S. Army when  the American Civil War broke out in April 1861, but his proposed strat�  egy of splitting the Confederacy�the plan eventually adopted�was ridi�  culed. Age forced his retirement the following November.</p><p>Sir Walter Scott, detail of an oil paint�  ing by Sir Edwin Henry Landseer,</p><p>1824; in the National Portrait Gallery,  London</p><p>COURTESY OF THE NATIONAL PORTRAIT GALLERY,  LONDON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Scott v.

Susie�s fold was caused by a genetic  mutation that does not appear in every kitten. The folded ear and a pedi�  gree that leads back to Susie are required for show. Scottish folds are  gentle and quiet.</p><p>Scottish Gaelic language Celtic language of northern Scotland, a  descendant of the Irish speech introduced into northern Britain by invad�  ers in the 4th-5th centuries. Gaelic gradually supplanted Pictish (see Picts)  as well as the British Celtic Lowlands dialects, and by the Middle Ages  it was the language of all of the Scottish Highlands and part of the Low�  lands. Until the 17th century, Classical Modem Irish (see Irish language)  was the literary medium of Gaeldom, and only after its collapse did writ�  ers regularly begin to use features that distinguish Scottish Gaelic dialects  from Irish dialects. Increasing Anglicization, suppression of traditional  culture after the Battle of Culloden, and the 19th-century land clearances  precipitated a marked decline; today it is probably a true community lan�  guage for fewer than 80,000 people, most of whom live on the north�  western coast and the Hebrides.</p><p>Scottish law Legal practices and institutions of Scotland. When the  English and Scottish parliaments were joined in 1707, the legal systems  of the two countries were very dissimilar. Scotland had supplemented its  customary law with civil-law principles adapted from the systems of  France and Holland. Its assimilation of English law following the union  was significant, particularly in the area of mercantile law. The supreme  Scottish civil court is the Court of Sessions, composed of 18 judges and  divided into Outer and Inner houses. The supreme criminal court is the  High Court of Justiciary. Below these two bodies are six sheriffdoms, each  with its own sheriff court, an institution of great antiquity. Lesser cases  are heard by district courts.</p><p>Scottish terrier or Scottie Short-legged terrier breed, perhaps the  oldest of the Highland terriers. A strong and plucky dog, the Scottie is  squat and bewhiskered, with alert-looking eyes and a distinctive rolling  gait. It stands about 10 in. (25.5 cm) tall and weighs 18-22 lb (8-10 kg).  Its hard, wiry coat may be of various colours.</p><p>Scotts Bluff National Monument National monument, western  Nebraska, U.S. Established in 1919, it has an area of 5 sq mi (13 sq km).  Its focus is a large bluff that rises 800 ft (244 m) above the North Platte  River and was a prominent landmark on the Oregon Trail. A museum at  the base of the bluff highlights the history of the pioneer travelers.</p><p>Scottsboro case U.S. civil-rights controversy. In April 1931, in Scotts-  boro, Ala., nine African American youths were charged with the rape of  two white women. Despite testimony by doctors that no rape had  occurred, the all-white jury convicted them and sentenced all but the  youngest to death. In 1932, following public outcry, the U.S. Supreme  Court overturned the convictions on the grounds that the defendants had  not received adequate legal counsel. Alabama retried and convicted one  of the youths; this conviction too was overturned by the Supreme Court  on the grounds that African Americans had been systematically excluded  from the state�s juries. Alabama retried and reconvicted the defendants  individually, but the state yielded to public pressure and freed or paroled  all but one, who later escaped.</p><p>Scotus, John Duns See John Duns Scotus</p><p>scouting Activities of various national and worldwide organizations for  youth aimed at developing character, citizenship, and individual skills.  Scouting began when Robert S. Baden-Powell published Scouting for Boys  (1908), in which he described the games and contests he used to train  cavalry troops in scouting, envisioning small groups of boys who would  learn tracking, reconnaissance, mapping, and other outdoor skills under a  peer leader. The Boy Scouts, as established by Baden-Powell, was for  boys 11-15 years old. The concept became so popular that separate orga�  nizations for girls (Girl Guides, or Girl Scouts, 1910) and for younger  boys (Wolf Cubs, or Cub Scouts, 1916) and older boys (Explorers) were  also formed.</p><p>Scrabble Game in which two to four players compete in forming words  with lettered wooden tiles on a 225-square board. Words spelled out by  letters on the tiles interlock like words in a crossword puzzle. Words are</p><p>scored by adding up the point values of their letters. The game (originally  called Lexico) was developed by Alfred Butts, an unemployed architect,  in 1931. It was redesigned and renamed Scrabble by Butts and James  Brunot in 1948. Tens of millions of sets have been sold in many languages  worldwide.</p><p>scrap metal Used metals that are an important source of industrial met�  als and alloys, particularly in the production of steel, copper, lead, alumi�  num, and zinc. Smaller amounts of tin, nickel, magnesium, and precious  metals are also recovered from scrap. Impurities consisting of such  organic materials as wood, plastic, paint, and fabric can be burned off.  Scrap is usually blended and remelted to produce alloys similar to or more  complex than those from which the scrap was derived.

In spite of their name, they do not  in fact screech. Their colouring resembles tree bark, and they are 8-12  in. (20-30 cm) long. They eat mostly small mammals, birds, and insects.  Notable species are the common screech owl ( O. asio) of North America,  the flammulated owl ( O. flammeolus) of western North America, and the  common scops owl ( O . scops) of southern Europe, Asia, and Africa.</p><p>screenplay Written text that provides the basis for a film production.  Screenplays usually include not only the dialogue spoken by the characters  but also a shot-by-shot outline of the film�s action. Screenplays may be  adapted from novels or stage plays or developed from original ideas sug�  gested by the screenwriters or their collaborators. They generally pass  through multiple revisions, and screenwriters are called on to incorporate  suggestions from directors, producers, and others involved in the filmmak�  ing process. Early drafts often include only brief suggestions for planned  shots, but by the date of production a screenplay may evolve into a detailed  shooting script, in which action and gestures are explicitly stated.</p><p>screw In machine construction, a usually circular cylindrical member  with a continuous spiral rib or thread, used either as a fastener or as a  force and motion modifier. Various types of screws are used to clamp  machine parts together. Wood screws are made in a wide variety of diam�  eters and lengths; when using wood screws, small starting holes called  pilot holes are often drilled first to avoid splitting the wood. Screws that  modify force and motion are known as power screws. The screw is con�  sidered one of the five simple machines. See also wedge.</p><p>screwworm Any of several North and South American blowfly species  named for the screwlike appearance of the larva�s body, which is ringed  with small spines. Screwworms attack livestock and other animals, includ�  ing humans. The true screwworm ( Cochliomyia hominivorax ) and the  secondary screwworm ( Callitroga macellaria) develop in decaying flesh;  they may also attack healthy tissue. Each female deposits 200-400 eggs  near an open wound. The larvae burrow into the tissue and, when mature,  drop to the ground to pupate. Severe infestations (myiasis) may kill the  affected animal.</p><p>Scriabin Vskrya-binV Aleksandr (Nikolayevich) (b. Jan. 6, 1872,  Moscow, Russia�d.

His early music was  mostly for piano (including etudes,  preludes, and sonatas) but also  included two symphonies and a  piano concerto. After 1900 he was  much preoccupied with mystical phi�  losophy and began using unusual  harmonies, producing a third sym�  phony and the Divine Poem (1904).</p><p>He became involved in theosophy,  which provided the basis for the  orchestral Poem of Ecstasy (1908)  and Prometheus (1910); the latter  called for the projection of colours  onto a screen during the perfor�  mance.

He was first employed by his half brother, James Edmund  Scripps (1835-1906), on newspapers in Detroit. He began publishing his  own papers in 1878 and eventually owned 34 in 15 states. He was a part�  ner in forming the first major U.S. newspaper chain, the Scripps-McRae  League of Newspapers (1894). In 1907 he consolidated regional Scripps  news services as United Press (after 1958, United Press International). In  1922 he transferred his interests to his son, Robert Paine Scripps (1895�  1938), who with Roy W. Howard formed the Scripps-Howard chain. The  E.W. Scripps Co. now operates the latter chain and includes varied media  holdings in addition to newspapers.</p><p>scripture Sacred writings of religions, comprising a large portion of the  literature of the world. Scriptures vary in form, volume, age, and degree  of sacredness. Nearly all scriptures were originally oral and were passed  down as memorized texts through several generations before being put in  writing. In some religions, notably Islam, Hinduism, and Buddhism, there is  still strong emphasis on the value of reciting or chanting the scriptures  aloud. The Hebrew Bible (Old Testament) is the scripture of Judaism; the  Bible (Old and New Testaments together) is the scripture of Christianity; and  the Qu�ran is the scripture of Islam. Scriptures of Hinduism include the  Vedas and Upanishads. See also Adi Granth; Avesta; Book of Mormon;  sutra; Tripitaka.</p><p>sc rod Young fish (as a cod or haddock), especially one split and boned  for cooking. The origin of the term is not known for certain, but it is  thought to come from an Old Dutch word meaning �to shred.� It seems  to have first been used around 1841.</p><p>scroll painting Art form practiced primarily in the Far East. The two  dominant types are the Chinese landscape scroll and the Japanese narra�  tive scroll. China�s greatest contribution to the history of painting, the  landscape hand scroll, reached its greatest period in the 10th-11th cen�  tury with such masters as Xu Daoning and Fan Kuan. The Japanese scroll  paintings of the 12th-13th century developed the storytelling potential of  painting to its greatest extent. In the earliest, Murasaki Shikibu�s literary</p><p>masterpiece The Tale of Genji, the narrative is told in pictures alternating  with text. Eventually the illustration stood nearly alone. Typical subjects  were the stories and biographies popular during Japan�s Middle Ages.</p><p>SCSI \'sko-ze\ in full Small Computer System Interface Once  common standard for connecting peripheral devices (disks, modems,  printers, etc.) to small and medium-sized computers. SCSI has given way  to faster standards, such as Firewire and USB.</p><p>scuba diving Swimming done underwater with a self-contained  underwater-breathing apparatus (scuba), as opposed to skin diving, which  requires only a snorkel, goggles, and flippers. Scuba gear was invented  by Jacques-Yves Cousteau and Emile Gagnan in 1943. Diving clubs  formed quickly as the technology became widely available. Scuba diving  is used in oceanography, in underwater exploration and salvage work, in  the study of water pollution, and for recreation.</p><p>sculpin or bullhead or sea scorpion Any of about 300 species  (family Cottidae) of inactive, bottom-dwelling fishes found principally in  northern regions. Sculpins are slender and tapered and have one or more  spines on the gill covers, large fanlike pectoral fins, and smooth or spiny  skin. The head is usually wide and heavy. Most species live in shallow  seawaters, some live in deeper waters, and others inhabit fresh water. The  largest species grow to 2 ft (60 cm) long; the miller�s-thumb ( Cottus  gobio), common in European lakes and rivers, is only about 4 in. (10 cm)  long. Other species of Cottus are found in Asia and North America.</p><p>sculpture Three-dimensional art produced especially by forming hard  or plastic materials into three-dimensional objects, usually by carving or  modeling. The designs may be produced in freestanding objects (i.e., in  the round), in relief, or in environments, and a variety of media may be  used, including clay, wax, stone, metal, fabric, wood, plaster, rubber, and  found objects. Materials may be carved, modeled, molded, cast, wrought,  welded, sewn, or assembled and combined. Various forms of sculpture  have been found in virtually every culture throughout history. Until the  20th century, sculpture was considered a representational art, but, begin�  ning in the early 1900, nonrepresentational works were increasingly pro�  duced. The scope of the term became much wider in the second half of  the 20th century. Present-day sculptors use any materials and methods of  manufacture that will serve their purposes, and so the art of sculpture can  no longer be identified with any special materials or techniques. See also  environmental sculpture; kinetic sculpture.</p><p>scurvy or vitamin C deficiency Nutritional disorder caused by defi�  ciency of vitamin C. Deficiency interferes with tissue synthesis, causing  swollen, bleeding gums; loose teeth; sore, stiff joints and legs; bleeding  under the skin and in deep tissues; slow wound healing; and anemia. The  scourge of sailors on long sea voyages, scurvy was recognized as diet-  related in 1753, when James Lind showed that drinking citrus juice could  cure and prevent it, leading to the concept of deficiency diseases. Full�  blown scurvy is now rare, and adequate vitamin C usually cures even  severe cases in days.</p><p>Scutari Vskti-ta-reV Lake Largest lake in the Balkan Peninsula. Located  on the frontier between Montenegro (see Serbia and Montenegro) and Alba�  nia, it has an area of 150 sq mi (390 sq km). It was formerly an arm of the  Adriatic Sea. Steep mountains, plains, and marshland border the lake, as do  many small villages that are noted for their old monasteries and fortresses.</p><p>Scylla and Charybdis \ , si-b...ko- , rib-dis\ In Greek mythology, two  monsters that guarded the narrow passage through which Odysseus had to  sail in his wanderings. These waters are now identified with the Strait of  Messina. On one shore was Scylla, a monster with six snaky heads, who  reached out of her cave to seize and devour six of Odysseus� companions.  On the opposite shore was Charybdis, the personification of a whirlpool,  who drank down and belched forth the waters three times a day. The ship�  wrecked Odysseus saved himself by clinging to a tree on the shore until  his raft floated to the surface.</p><p>Scythian \'si-the-on\ Any member of a nomadic people of Iranian stock  who migrated from Central Asia to southern Russia in the 8th-7th cen�  tury bc. Fierce warriors, they were among the first expert horsemen, which  enabled them to establish an empire from western Persia through Syria  and Judaea to Egypt and to expel the Cimmerians from their territory in the  Caucasus and north of the Black Sea. Although driven out of Anatolia by  the Medes (see Media), they held territory from the Persian border into  southern Russia; they repelled an invasion by the Persian Darius I c. 513  bc. Their civilization produced wealthy aristocrats (�Royal Scyths�),</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Scythian art &#x25BA; sea level I 1709</p><p>whose graves held richly worked articles of gold and other precious mate�  rials.

Also known  as Steppes art, it largely features rep�  resentations of real or mythical  beasts worked in a wide variety of  materials, including wood, leather,  bone, applique felt, bronze, iron, sil�  ver, gold, and electrum. Outstanding  are gold stags about 12 in. (30 cm)  long, their legs tucked under them,  probably used as central ornaments  on round shields.</p><p>SDI See Strategic Defense Initiative  SDS See Students for a Democratic Society</p><p>Sea, Law of the International law codified in a treaty signed in 1982  covering the status and use of territorial waters, sea lanes, and ocean  resources. Originally signed by 117 countries, the treaty had some 140  state parties by the early 21st century. The treaty defines territorial waters  as those extending 12 nautical mi (22 km) beyond a country�s coast and  gives to each country exclusive fishing and mining rights in waters extend�  ing to 200 nautical mi (370 km) from its coast. See also high seas.</p><p>sea anemone \3-,ne-m9-,ne\ Any of more than 1,000 cnidarian spe�  cies in the order Actiniaria, found  from the tidal zone of all oceans to  depths of more than 30,000 ft  (10,000 m) and occasionally in  brackish water. Species vary from  less than 1 in. (3 cm) to about 5 ft  (1.5 m) in diameter. The mouth, at  the upper end of the cylindrical body,  is surrounded by petal-like, usually  colourful tentacles that bear stinging  nematocysts for paralyzing prey  such as fishes. Some species eat only  microorganisms. Most species  remain permanently attached to a  hard surface such as a rock or the back of a crab.</p><p>sea bass Any of about 400 species (family Serranidae) of carnivorous  fishes, most of which inhabit shallow regions of warm and tropical seas.  Sea bass have a slender body, small scales, large mouth, and straight-  edged or rounded tail. The spiny frontal section and the soft-rayed rear  section of the dorsal fin are usually joined but may be separated by a  notch. Species range from about 1 in. (3 cm) to 6 ft (1.8 m) long and may  weigh 500 lbs (225 kg). About 12 species in the family Moronidae (some�  times considered a subfamily of Serranidae) inhabit temperate waters. See  also BASS.</p><p>sea coot See scoter</p><p>sea cow or Steller's sea cow Extinct aquatic mammal ( Hydroda-  malis gigas) that lived around islands in the Bering Sea. It was discov�  ered in 1741 and described by a member of Vitus Bering�s expedition. At  least 24 ft (7.5 m) long, it had no teeth, a small head, and a broad, hori�  zontal, forked tail fluke; its dark brown skin was sometimes streaked or  spotted with white. It browsed on seaweed. Russian sealers hunted it for  food and fur; by 1768 the entire population, estimated at about 5,000, had  been exterminated. The term also refers to dugongs and manatees.</p><p>sea cucumber Any of 1,100 species of echinoderms constituting the  class Holothurioidea, found in all oceans, mostly in shallow water. The  soft, cylindrical body is 0.75 in. (2 cm) to 6.5 ft (2 m) long and 0.4-8 in.</p><p>(1-20 cm) thick. It is usually dull, dark, and often warty. The internal  skeleton consists merely of numerous tiny bits in the skin. Most species  have five rows of tube feet extending from mouth to anus. The 10 or more  retractile tentacles surrounding the mouth are used for taking food (mud  containing nutrients or small aquatic animals) or burrowing. Locomotion  is sluglike. See also shellfish.</p><p>sea eagle Any of various large fish-eating eagles (especially in the  genus Haliaeetus ), of which the best known is the bald eagle. Sea eagles  live along rivers, big lakes, and tidewater worldwide except in South  America. Some reach over 3 ft (1 m) long. All have an exceptionally large,  high-arched beak and bare lower legs. The toes� undersurfaces are rough�  ened for grasping slippery prey. They eat mostly carrion but sometimes  kill, snatching fish from the water surface and often robbing their chief  competitor, the osprey. Asian species include the gray-headed, or greater,  fishing eagle and the lesser fishing eagle.</p><p>sea fan Any of about 500 coral species (genus Gorgonia) especially  abundant in shallow waters along the  Atlantic coasts of Florida, Bermuda,  and the West Indies. Polyps grow  colonially in a flat, fanlike pattern.</p><p>Each polyp has some multiple of six  tentacles, which it spreads out to  form a plankton-catching net. An  internal skeleton supports all  branches of the colony. The living  tissues (often red, yellow, or orange)  entirely cover the skeleton. The fan�  shaped colonies usually grow across  the current, increasing their ability to  ensnare prey. All species grow to  about 2 ft (60 cm) high.</p><p>sea horse Any of about 24 species  (family Syngnathidae) of fishes that  usually live along warm seashores,  clinging to plants with their forward-  curled, prehensile tail. Species range  from 1.5 to 12 in. (4-30 cm) long.</p><p>Sea horses have bony rings instead  of scales, and their eyes can move  independently. They swim upright,  propelling themselves horizontally  with their fins and vertically with  their swim bladder. They catch small  organisms by sucking them quickly  into their small mouths. The female  deposits her eggs into a brood pouch  beneath the male�s tail, and the male  expels the newly hatched young.</p><p>sea ice Ice formed from frozen sea�  water in polar regions. Most sea ice  occurs as pack ice, which drifts  across the ocean surface; other types  of sea ice include fast ice, which is  attached to coasts and sometimes the seafloor or between grounded ice�  bergs, and marine ice, which forms at the bottom of ice shelves in Ant�  arctica. The sea ice of the Northern Hemisphere covers about 3 million  sq mi (8 million sq km) in September and about 6 million sq mi (15 mil�  lion sq km) in March. Sea ice in the Southern Hemisphere ranges from  about 1.5 million sq mi (4 million sq km) in February to about 8 million  sq mi (20 million sq km) in September.</p><p>sea lavender Any of about 300 species of chiefly perennial herbaceous  plants that make up the genus Limonium of the family Plumbaginaceae,  especially L. vulgare. Bearing small flowers in dense spikes, L. vulgare  grows in large tracts that sometimes turn acres lilac-coloured in late sum�  mer. The flower spikes of this and other sea lavenders are often used in  dry-flower arrangements for their lasting qualities and permanent colours.</p><p>sea leopard See leopard seal</p><p>sea level Position of the air-sea boundary, to which all terrestrial eleva�  tions and submarine depths are referred.

Sea lions have  short, coarse hair that lacks a distinct undercoat. The males of all but the  California sea lion have a mane. Sea lions feed principally on fish, squid,  and octopus. They breed in large herds; males establish a harem of 3-20  females. The California sea lion ( Zalophus califomianus ) is the trained seal  of circuses and zoos. Males of the various species range from 8 to 11 ft  (2.5-3.3 m) long and weigh 600-2,200 lbs (270-1,000 kg).</p><p>sea otter or great sea otter Rare, completely marine otter ( Enhy-  dm lutris) of the northern Pacific, usually found in kelp beds. Floating on  its back, it opens mollusks by smashing them on a stone balanced on its  chest. The large hind feet are broad and flipperlike. It is 40-65 in. (100-  160 cm) long and weighs 35-90 lbs (16-40 kg). The thick lustrous coat  is reddish to dark brown. By 1910 it had been hunted almost to extinc�  tion for its fur; now fully protected, it is gradually increasing in numbers.</p><p>sea parrot See puffin</p><p>Sea People Any of the groups of aggressive seafarers who invaded  eastern Anatolia, Syria, Palestine, Cyprus, and Egypt toward the end of  the Bronze Age. They were especially active in the 13th century bc.  Though the extent and origin of the upheavals remain uncertain, Sea  Peoples are believed responsible for the destruction of old powers such  as the Hittite empire. The Egyptians waged two wars against them  (1236-23 bc and c. 1198-66). The only major tribe to settle permanently  in Palestine were the Peleset (i.e., Philistines).</p><p>sea power Means by which a nation extends its military power onto  the seas. Measured in terms of a nation�s capacity to use the seas in defi�  ance of rivals, it consists of combat vessels and weapons, auxiliary craft,  commercial shipping, bases, and trained personnel. It includes aircraft  based on carriers or used in support of shipping. Its main purpose is to  protect friendly shipping from enemy attack and to destroy or hinder the  enemy�s shipping. It may also be used to enforce a blockade. Finally, naval  forces have been used to bombard land targets from the sea. The aircraft  carrier added a new dimension to this capability, as did the missile-firing  nuclear submarine. The classic exposition of the role of sea power as the  basis of national greatness is Alfred Thayer Mahan�s The Influence of Sea  Power upon History (1890).</p><p>sea scorpion See sculpin  sea slug See nudibranch</p><p>sea snake Any of some 50 species (family Hydrophiidae) of venom�  ous, marine snakes with an oarlike tail and flattened body. Most are found  along coasts and in estuaries of Australia and Asia, sometimes basking on  the surface in a large group, though the yellow-bellied, or pelagic, sea  snake ranges throughout the Pacific. The nostrils, usually on top of the  snout, have valvelike closings. The body of several species is much  thicker than the head and neck. Most species are 3-4 ft (1�1.2 m) long;  Laticauda semifasciata, a Japanese delicacy, may be twice as long.  Though generally slow to strike, their venom may be lethal.</p><p>sea squirt Any tunicate in the class Ascidiacea; found in seas world�  wide. Resembling potatoes more than animals, they are permanently fixed  to a surface. A forceful contraction of the adult�s vaselike body shoots a  jet of seawater when it is disturbed. They filter-feed near the shore on  debris from dead plants and animals and, in deeper water, on plankton.  Adults, from less than 1 in. to 1 ft (2-30 cm) long, have functional male  and female reproductive organs. The free-swimming, tadpolelike larvae  hatch from eggs shed by one individual and fertilized by another. Some  species live individually, others in colonies.</p><p>sea star See starfish  sea trout See weakfish</p><p>sea urchin Any of about 700 species (class Echinoidea) of echinoderms  found worldwide. Sea urchins have a globular body covered with mov�  able, sometimes poisonous, spines up to 12 in. (30 cm) long. Pores along  the internal skeleton accommodate slender, extensible, often sucker-  tipped tube feet. Sea urchins live on the seafloor and use their tube feet  or spines to move about. The mouth is on the body�s underside; teeth are</p><p>extruded to scrape algae and other  food from rocks. Some species exca�  vate hiding places in coral, rock, or  even steel. Roe of some species is  eaten in certain countries.</p><p>Seaborg Yse-.borgV, Glenn  (Theodore) (b. April 19,1912, Ish-  peming, Mich., U.S.�d. Feb. 25,</p><p>1999, Lafayette, Calif.) U.S. nuclear  chemist. Seaborg pursued graduate  study at the University of California  at Berkeley. Working with John Liv-  ingood, Emilio Segre, and others, he  discovered some 100 isotopes,  including many that would prove to  be of major importance, such as  iodine-131 and technetium-99. How�  ever, his best-known work involved the isolation and identification of tran�  suranium elements. In 1941 he and his colleagues discovered plutonium. He  went on to discover and isolate the elements americum, curium, berkelium,  californium, einsteinium, fermium, mendelevium, and nobelium (atomic  numbers 95-102). He joined the Manhattan Project in 1942 and was instru�  mental in the development of the atomic bomb, although he pleaded, unsuc�  cessfully, with Pres. Truman not to use the bomb on civilian targets. He  shared a 1951 Nobel Prize with Edwin Mattison McMillan (1907-91). Pre�  diction of new elements� chemical properties and placement in the periodic  table was helped greatly by an important organizing principle enunciated by  Seaborg, the actinide concept. He served as head of the Atomic Energy  Commission (1961-71). A strong advocate of nuclear disarmament, he led  the negotiations that eventuated in the Limited Nuclear Test-Ban Treaty  (1963) and later played a leading role in the passage of the Nuclear Non�  proliferation Treaty. In 1997 his name was given to the new element  seaborgium, the first time a living person had been so honoured.</p><p>seafloor spreading Theory that oceanic crust forms along subma�  rine mountain zones, known collectively as the oceanic ridge system, and  spreads out laterally away from them. This idea, proposed by U.S. geo�  physicist Harry H. Hess (1906-1969) in 1960, was pivotal in the devel�  opment of the theory of plate tectonics.</p><p>seafood Edible aquatic animals excluding mammals, but including both  freshwater and ocean creatures. Seafood includes bony and cartilaginous  FISHeS, CRUSTACEANS, MOLLUSKS, edible JELLYFISH, Sea TURTLES, FROGS, SEA URCHINS,  and sea cucumbers. The roe, or eggs, of some species are eaten as caviar.  After cereals, seafood may be mankind�s most important food, furnish�  ing about 15% of the world�s protein intake. Lean fish is equivalent to  beef or poultry in its protein yield (18-25% by weight), but it is much  lower in calories. Much seafood is eaten uncooked, either raw, dried,  smoked, salted, pickled, or fermented. Otherwise it is cooked whole or  cut into steaks, filets, or chunks. It is often used in stews or soups.</p><p>Seagram Building High-rise office building in New York City (1958).  Designed by Ludwig Mies van der Rohe and Philip Johnson, this sleek Park  Avenue skyscraper is a pure example of a rectilinear prism sheathed in  glass and bronze; it took the International Style to its zenith. Despite its  austere and forthright use of the most modem materials, it demonstrates  Mies�s exceptional sense of proportion and concern for detail.</p><p>Seagram Company Ltd. Formerly the world�s largest producer and  marketer of distilled spirits. The company began when Distillers Corp.,  Ltd., a Montreal distillery owned by Samuel Bronfman, acquired Joseph  E. Seagram &amp; Sons in 1928. The new company, Distillers Corp.-Seagrams  Ltd., grew rapidly. Originally a maker of blended whiskies, the firm diver�  sified in the 1950s and �60s into scotch, bourbon, rum, vodka, gin, and  wines, which were sold around the world. In the 1990s it entered the field  of music and entertainment, purchasing Universal Studios, media firm  MCA, and the Dutch music giant Polygram NV. The company was  acquired by French media conglomerate Vivendi in 2000 to form Vivendi  Universal. The beverage businesses were later sold to Diageo and Pernod  Ricard.

Virtually every oceanographic expedition discovers new sea�  mounts, and it is estimated that about 20,000 exist worldwide.</p><p>seaplane Aircraft that can land, float, and take off on water. The first  practical seaplanes were built and flown in 1911-12 by Glenn H. Curtiss,  who developed both the float seaplane, essentially a land plane with pon�  toons instead of landing wheels, and the flying boat, a boatlike plane that  combined a main float and fuselage in a single body. A retractable land�  ing wheel was later added to create an amphibian aircraft. By the late  1920s seaplanes held the speed and range records for aircraft. During the  1940s their utility diminished with the building of long-range land-based  airplanes, new airports, and aircraft carriers.</p><p>search and seizure In law enforcement, an exploratory investigation  of a premises or a person and the taking into custody of property or an  individual in the interest of gaining evidence of unlawful activity or guilt.  The latitude allowed police in carrying out searches and seizures varies  greatly from country to country. In the U.S., the 4th Amendment to the  Constitution prohibits unreasonable searches and seizures and requires  that a warrant be issued following a finding of probable cause. The war�  rant must specify the place to be searched and the persons and things to  be seized.</p><p>search engine Tool for finding information, especially on the Internet  or World Wide Web. Search engines are essentially massive databases that  cover wide swaths of the Internet. Most consist of three parts: at least one  program, called a spider, crawler, or bot, which �crawls� through the  Internet gathering information; a database, which stores the gathered  information; and a search tool, with which users search through the data�  base by typing in keywords describing the information desired (usually  at a Web site dedicated to the search engine). Increasingly, metasearch  engines, which search a subset (usually 10 or so) of the huge number of  search engines and then compile and index the results, are being used.</p><p>Sears, Isaac (b.

As a member of the radi�  cal Sons of Liberty, he headed a boycott of British goods to protest the  Townshend Acts. He led the ouster of loyalist officials from New York  City and seized control of the municipal government until George Wash�  ington�s troops arrived (1775). From Boston he organized privateers to  prey on British ships. He died while on a trading venture in China.</p><p>Sears, Roebuck and Company U.S. merchandising company, his�  torically one of the world�s largest retailers. It was founded in 1893 by  Richard W. Sears (1863-1914) and Alvah C. Roebuck (1864-1948). The  company grew rapidly, selling mail-order merchandise at low prices to  rural dwellers who lacked access to competitive retail outlets. Under Rob�  ert E. Wood (president 1928-54), Sears built stores across the U.S., and by  1931 its retail sales had topped its mail-order sales. It diversified into finan�  cial services in the 1980s and introduced the Discover credit card in 1985,  but in 1992 it began shedding its financial-services subsidiaries. It discon�  tinued its famous catalog in 1993 and spun off insurance subsidiary Allstate  (founded by Sears in 1931) in 1995. A merger with Kmart in 2005 brought  the two retail chains under the leadership of Sears Holdings Corporation.</p><p>Sears Tower Skyscraper office building in Chicago.

Situated between Elliott Bay (Puget  Sound) and Lake Washington, it is flanked by the Olympic Mountains and  the Cascade Range. Laid out in 1853, it withstood an Indian attack (1856),  anti-Chinese riots (1880s), and a disastrous fire (1889) to emerge as the  gateway to the Orient and Alaska. It was the main supply depot for the  Yukon and Alaskan gold rushes (see gold rush) in the 1890s. World War  II brought a great boom to the city, with shipyards and the aircraft indus�  try playing important roles. Seattle Center, site of the 1962 World�s Fair,  contains the 607-ft (185-m) Space Needle.

He was the  first unbeaten racer ever to win the Triple Crown (1977). In his racing  career of 17 races, he won 14, was second twice, and fourth once. He was  retired to stud in 1978.</p><p>seawater Water that makes up the oceans and seas. Seawater is a com�  plex mixture of 96.5% water, 2.5% salts, and small amounts of other sub�  stances. Much of the world�s magnesium is recovered from seawater, as  are large quantities of bromine. In certain parts of the world, sodium  chloride (table salt) is obtained by evaporating seawater. In addition,  desalted seawater can theoretically furnish a limitless supply of drinking  water, but the high processing costs are prohibitive. Large desalination  plants have been built in dry areas along seacoasts in the Middle East and  elsewhere to relieve shortages of fresh water.</p><p>seaweed Any of certain species of red, green, and brown marine algae  that generally are anchored to the sea bottom or to a solid structure by  rootlike holdfasts that perform the sole function of attachment and do not  extract nutrients as do the roots of higher plants. The most obvious sea�  weeds are brown algae; mosslike carpets of red algae are seen at low tides.  Seaweeds are often dense in shallow water. Brown algae commonly found  as seaweeds include kelp, which include the largest algae, and sargassum.  Some seaweeds have hollow, gas-filled floats that keep their fronds at the  surface of the water. Ulva species, commonly called sea lettuce, are  among the relatively few green algae that are seaweeds. Seaweeds are  used as food, and brown algae are used in fertilizers. The red alga Gelid-  ium is used to make the gelatin-like product called agar.</p><p>sebaceous gland \si-'ba-sh3s\ Small oiL-producing gland in the skin,  usually connected to a hair follicle by a duct into which it releases sebum,  a component of the slightly greasy film on the skin that helps keep it flex�  ible and prevents too much water loss or absorption. The glands are dis�  tributed over the entire body except the palms and soles, most abundantly  on the scalp and face. Large and well developed at birth, they shrink dur�  ing childhood but enlarge again and increase their sebum output at puberty  (apparently in response to male hormones), often leading to acne.</p><p>Sebastian, Saint (d. c. 288, Rome; feast day January 20) Christian  martyr who died during the persecutions of Diocletian. According to leg�  end, he was born in Gaul and went to Rome to serve in the army. When  officials learned that he was a Christian seeking converts, they ordered his  execution by archers. Left for dead, he was nursed back to health by a  Christian widow. He presented himself before the emperor, who con�  demned him to death by beating. His body was thrown into a sewer but</p><p>was afterward found and buried. In Renaissance art he was often depicted  as a handsome youth pierced by arrows.</p><p>Sebastiano del Piombo \se-bas-'tya-no-del-'py6m-bo\ orig.  Sebastiano Luciani (b. c. 1485, Venice, Republic of Venice�d. July  21, 1547, Rome, Papal States) Italian painter. While in Venice, he was  highly influenced by his teacher, Giorgione. In 1511 he moved to Rome  and became a member of Michelangelo�s circle of Renaissance artists.  Michelangelo thought so highly of him that he provided sketches for him  to execute. In Sebastiano�s Pieta (1513), Flagellation (1516-24), and  Raising of Lazarus (1516-18), all based on Michelangelo�s sketches, he  combined the warm colouring of the Venetian school with Michelange�  lo�s anatomical clarity and firm sculptural drawing. After Raphael�s death,  Sebastiano�s reputation as a portraitist was unparalleled. In 1531 Pope  Clement VII, the subject of one of his finest portraits (1526), appointed  him keeper of the papal seal; his nickname derives from the fact that the  seal was of lead (Italian, piombo). The lucrative post gave him financial  security, and his output declined.</p><p>Sebastopol See Sevastopol</p><p>Sebek Vse-,bek\ In ancient Egyptian  sanctuary in Fayyum province  included a sacred crocodile, which  was believed to be an incarnation of  the god. Sebek may have been asso�  ciated with fertility or death and  burial before becoming a major deity  and patron of kings in the Middle  Kingdom (c. 1938-c. 1600? bc). He  was merged with Re, the sun god, to  constitute a crocodile form of that  deity known as Sebek-Re. The wor�  ship of Sebek continued in Ptolemaic  and Roman times.</p><p>Sebou \s3-'bii\ River River, north�  ern Morocco. From its source as the  Wadi Guigou, it flows north to Fes  and then east to the Atlantic Ocean at  Mehdiya, a distance of 280 mi (450  km). Its basin is a major region for  cultivating olives, rice, wheat, sugar  beets, and grapes. Kenitra (pop.,</p><p>1994: 292,627), 10 mi (16 km) from  its mouth, is a busy port at the head of  navigation for oceangoing vessels.</p><p>secession (1860-61) Withdrawal  of 11 Southern states from the U.S.</p><p>The precipitating event was the elec�  tion of Abraham Lincoln as president  (1860). Since the Republican Party  strongly opposed slavery and its  extension into the new territories,  most slaveholding states had vowed  to secede if the Republican candidate  won. Secession had been proclaimed  by states�-rights advocates as a cor�  ollary to the compact that united the  states, permitting them to withdraw  as easily as they had joined. Earlier  threats of secession were made at the  Hartford Convention (1814), in the  nullification crisis (1832), and in the 1850s before the Missouri Compro�  mise. Secession was first approved by South Carolina (1860); six other  states followed in the period before Lincoln was inaugurated in March  1861. After Lincoln resisted the South�s attack on Fort Sumter, four other  slaveholding states voted to secede, joining the newly formed Confeder�  ate States of America.</p><p>Second Empire (1852-70) Period in France under the rule of Emperor  Napoleon III (the original empire having been that of Napoleon). In its  early years (1852-59), the empire was authoritarian but enjoyed economic  growth and pursued a favourable foreign policy.

In 1870 a new constitution  establishing a quasi-parliamentary regime was widely approved, but  France�s defeat at the Battle of Sedan in the Franco-Prussian War was  followed by an uprising in Paris on Sept. 4, 1870. This resulted in the  overthrow of the government, the abdication of Napoleon III, and the end  of the Second Empire.</p><p>Second Empire style See Beaux-Arts style</p><p>Second International or Socialist International (1889-1914)  Federation of socialist political parties and trade unions that greatly influ�  enced the European labour movement while supporting parliamentary  democracy and opposing anarchism. Unlike the centralized First Interna�  tional, it was a loose federation that met in a number of cities at various  intervals. By 1912 it represented the socialist parties of all European coun�  tries, the U.S., Canada, and Japan, with a membership of about nine mil�  lion. It reaffirmed Marxist doctrine, but its main concern became the  prevention of a general European war. When that failed, the International  ended in 1914.</p><p>Second Republic (1848-52) French republic established after the  Revolutions of 1848 (following the original republic during the French  Revolution). The liberal republicans� hopes of establishing an enduring  democratic regime were soon frustrated. In 1848 Louis-Napoleon (later  Napoleon III) was elected president, and a monarchist majority was elected  to the legislative assembly, which passed conservative measures restrict�  ing voting rights and freedom of the press and giving the church increased  control over education. Soon realizing that his power and future reelec�  tion were limited by the assembly�s actions, Louis-Napoleon organized a  coup d�etat in 1851. A new constitution reduced the assembly�s power,  and a plebiscite to approve the change was accompanied by officially  inspired petitions for the empire�s restoration. In 1852 Louis-Napoleon  was proclaimed emperor, and the Second Empire was bom.</p><p>secondary education Traditional second stage in formal education,  typically beginning at ages 11-13 and ending usually at ages 15-18. The  distinction between elementary education and secondary education has  gradually become less marked, because of the proliferation of middle  schools, junior high schools, and other divisions.</p><p>secret police Police established by national governments to maintain  political and social control. Generally clandestine, secret police have oper�  ated independently of the civil police. Particularly notorious examples  were the Nazi Gestapo, the Russian KGB, and the East German Stasi.  Secret-police tactics include arrest, imprisonment, torture, and execution  of political enemies and intimidation of potential opposition members.</p><p>secret society Any of various oath-bound societies devoted to broth�  erhood (or sisterhood), moral discipline, and mutual assistance. Such soci�  eties usually conduct rituals of initiation to instruct new members in the  rules of the group (see rite of passage). Greek and Roman mystery religions  had their secular counterparts in clandestine social clubs, some of which  served as platforms for political dissent. In West Africa secret societies  such as Poro (for men) and Sande (for women) serve to translate slight  advantages of wealth and prestige into political authority. In parts of New  Guinea secret men�s societies serve as repositories of tribal knowledge.  Fraternal orders such as the Freemasons (see Freemasonry) may be con�  sidered secret societies, as may criminal groups such as the Mafia and the  Chinese Triads and hate groups such as the Ku Klux Klan.</p><p>Secretariat (foaled 1970) U.S. Thoroughbred racehorse. In 1973 he  became the first Triple Crown winner since Citation in 1948. At the Bel�  mont Stakes he won by an unprecedented 31 lengths. In his two-year career  he came in first 16 times, second 3 times, and third once. He is often  regarded as the greatest Thoroughbred in history.</p><p>secretary bird African raptor (Sagittarius serpentarius, family Sagit-  taridae), the only living bird of prey that hunts on foot. It has long scaly legs,  a light-gray body that is 4 ft (1.2 m) long, and a 7-ft (2.1-m) wingspread. It  weighs about 8 lbs (3.5 kg). Twenty black crest feathers make it appear to  be carrying quill pens behind its ears. Secretary birds kill snakes (their main  prey) by stamping on them, flailing them against the ground, or dropping  them from aloft. They make their large stick-built nests in thorn trees. Both  parents feed the offspring by regurgitation. Secretary birds are protected in  most African nations. See photograph opposite.</p><p>Secular Games Latin Ludi saeculares Celebrations held in ancient  Rome at the beginning of a new saeculum, or generation. Similar games</p><p>were originally held by the Etruscans as offerings to the underworld gods.  The Romans initially worshiped the underworld gods but later introduced  Apollo, Diana, and Leto in a festival that lasted three days and nights. More  days were added later. The first known Roman games were held in 249  bc, the second in 146, and the third in 17 under Caesar Augustus. Later  games, held in ad 47, 88, 147, 204, 248, and 262, included sports, music,  theatre, and circuses. The games ceased in the 4th century ad under Con�  stantine I, who converted to Christianity.</p><p>Securities and Exchange Commission (SEC) U.S. regulatory  commission established by Congress in 1934. Its purpose was to restore  investor confidence by ending the misleading sales practices and stock  manipulations that had led to the stock market�s 1929 collapse (see Stock  Market Crash of 1929). It also prohibited the purchase of stock shares  without adequate funds to pay for them, initiated registration and super�  vision of securities markets and stockbrokers, established rules regarding  proxies, and prohibited unfair use of nonpublic information in stock trad�  ing (see insider trading). It also required that companies offering securi�  ties make full public disclosure of all relevant information. The discovery  of fraudulent accounting practices among several large U.S. corporations  brought demands for greater SEC oversight in the early 21st century.</p><p>security In finance, written evidence of ownership conferring the right  to receive property not currently in the holder�s possession. The most  common securities are stocks and bonds. Governments, companies, and  financial institutions use securities to raise money. Stocks are securities  issued in the form of equity ownership. Bonds are securities that take the  form of debt. They constitute promises to pay a specified amount at a  specified date and to pay interest at a specified rate in the interim. Most  government securities are bonds that pay a fixed amount of interest per  year; unlike commercial securities, their repayment is guaranteed. Both  stocks and bonds are traded publicly on organized exchanges such as the  New York Stock Exchange, the London Stock Exchange, and the Tokyo  Stock Exchange. External forces such as international troubles, changes in  government policies, and trends in foreign stock markets all have an effect  on security prices. For individual stocks, the company�s current and pro�  spective financial performance play an important role, as do overall trends  within its business sector.

Battle of (Sept. 1, 1870) Defeat of  the French army in the Franco-Prussian War that led to the fall of the  Second Empire. At the French border fortress of Sedan on the Meuse River,  120,000 French troops under Maurice, count de Mac-Mahon, were  attacked by more than 200,000 German troops under Helmuth von Moltke.  After Mac-Mahon was wounded, the confused French command tried  unsuccessfully to break through the encircling German lines with massive  cavalry charges. Emperor Napoleon III. who had accompanied Mac-  Mahon, realized the French position was hopeless and surrendered with  83,000 troops.</p><p>Seder \'sa-dor\ Ritual meal served on the first night of Passover, com�  memorating the flight of the Jews from Egypt.

The meal includes unleavened bread and bitter herbs,  the bread symbolizing the haste with which the Israelites left Egypt and  the herbs symbolizing the bitterness of slavery. A cup of wine is poured  for Elijah, the precursor of the Messiah.</p><p>sedge family Family Cyperaceae, one of the 10 largest families of  flowering plants, composed of about 5,000 species of grasslike herbs that  inhabit wet regions worldwide. Sedges are monocots (see cotyledon) of  extraordinary ecological importance; forming the base of food webs, they  provide food and shelter for aquatic and wetland animals. They are also  important as ornamentals and weeds, and are used in woven products such  as mats, baskets, screens, and sandals. Key identifying characteristics that  distinguish sedges from grasses are solid stems that are often triangular  in cross section; leaves, when present, that clasp the stem with a sheath;  and small spikes of minute flowers that are not enclosed in bracts. They  range in height from about 1 in. to 13 ft (2 cm-4 m). The genus Carex  represents the true sedges. Papyrus and bulrushes are also included in this  family.</p><p>Sedgwick, Adam (b. March 22, 1785, Dent, Yorkshire, Eng.�d. Jan.  27, 1873, Cambridge, Cambridgeshire) English geologist. A pioneer in  the establishment of geology as a university discipline (Trinity College,  Oxford), he named the Cambrian Period and (with Roderick Murchison)  the Devonian Period. His grandnephew, the zoologist Adam Sedgwick  (1854-1913), first established the evolutionary link between the annelids  and the arthropods.</p><p>sedimentary facies \'fa-shez\ Different, but contemporaneous and  juxtaposed, sedimentary rocks. Terrigenous facies are accumulations of  particles eroded from older rocks and transported to the depositional site.  Biogenic facies are accumulations of whole or fragmented shells and other  hard parts of animals. Chemical facies result from precipitation of inor�  ganic material from solution. The shapes and characteristics of facies may  change as conditions change over time.</p><p>sedimentary rock Rock formed at or near the Earth�s surface by the  accumulation and lithification of fragments of preexisting rocks or by pre�  cipitation from solution at normal surface temperatures. Sedimentary  rocks can be formed only where sediments are deposited long enough to  become compacted and cemented into hard beds or strata. They are the  most common rocks exposed on the Earth�s surface but are only a minor  constituent of the entire crust. Their defining characteristic is that they are  formed in layers. Each layer has features that reflect the conditions dur�  ing deposition, the nature of the source material (and, often, the organ�  isms present), and the means of transport. See also sedimentary facies.</p><p>sedimentation In geology, the process of deposition of a solid mate�  rial from a state of suspension or solution in a fluid (usually air or water).  Broadly defined it also includes deposits from glacial ice and materials  collected under the effect of gravity alone, as in talus deposits, or accu�  mulations of rock debris at the base of cliffs.</p><p>sedimentology Scientific discipline concerned with the physical and  chemical properties of sedimentary rocks and the processes involved in  their formation, including transportation, deposition, and lithification of  sediments. The aim of much sedimentological research is to interpret  ancient environmental conditions by studying the constituents, textures,  structures, and fossil content of the deposits.</p><p>sedition Crime of creating a revolt, disturbance, or violence against  lawful civil authority with the intent to cause its overthrow or destruction.  Because it is limited to organizing and encouraging opposition to gov�  ernment rather than directly participating in its overthrow, sedition is  regarded as falling one step short of the more serious crime of treason.  In the U.S. the display of a certain flag or the advocacy of a particular  movement, such as syndicalism, anarchism, or communism, has periodically  been declared seditious. More recently, the courts have applied a more  stringent test of sedition to ensure that constitutional guarantees regard�  ing freedom of speech are not abridged. See also Alien and Sedition Acts.</p><p>sedum Vse-domX Any of about 600 species of succulent plants that make  up the genus Sedum, in the stonecrop, or orpine, family (Crassulaceae),  native to temperate zones and to mountains in the tropics. Some species  are grown in greenhouses for their unusual foliage and sometimes showy</p><p>flowers of white, yellow, pink, or red. Low-growing varieties are popular  in rock gardens and rock walls, and as edging in garden borders. Some  species form mosslike mats on rocks and walls.</p><p>Seeckt \'zakt\, Hans von (b. April 22, 1866, Schleswig, Prussia�d.  Dec. 27, 1936, Berlin, Ger.) German general. A career army officer, in  World War I he was chief of staff of the 11th Army and then chief of staff  of the Turkish army. After the war he became head of the German Reichs-  wehr (1919-26) and secretly built a small but efficient army, circumvent�  ing the Treaty of Versailles prohibition. He supported cooperation with  Russia and encouraged the Treaty of Rapallo. He later served as an adviser  to the Chinese Nationalist Army (1934-35).</p><p>seed Reproductive structure in plants that consists of a plant embryo,  usually accompanied by a supply of food (endosperm, which is produced  during fertilization) and enclosed in a protective coat. Seed embryos con�  tain one or more cotyledons. In typical flowering plants, seed production  follows pollination and fertilization. As seeds mature, the ovary that  enclosed the ovules develops into a fruit containing the seeds. Most seeds  are small, weighing less than a gram; the smallest contain no food reserve.  At the opposite extreme, the seed of the double coconut palm may weigh  up to about 60 lb (27 kg). Seeds are highly adapted to transportation by  animals, wind, and water. When circumstances are favorable, water and  oxygen penetrate the seed coat, and the new plant begins to grow (see  germination). The longevity of seeds varies widely: some remain viable  for only about a week; others have been known to germinate after hun�  dreds or even thousands of years.</p><p>seed plant or spermatophyte Vspor-'ma-to-.fflA Any of the flower�  ing plants (angiosperms) and the conifers and related plants (gymnosperms).  Seed plants share many features with ferns, including the presence of vas�  cular tissue (see xylem and phloem), but unlike ferns, they have stems that  branch sideways and vascular tissue that is arranged in strands (bundles)  around the core. Seed plants have generally more complex plant bodies  and reproduce via seeds. As the main dispersal unit of seed plants, the  seed represents a significant improvement over the spore, with its limited  capacity for survival. Seed plants also differ from ferns in having game-  tophytes that are reduced in size and are embedded in the sporophytes (and  thus are less vulnerable to environmental stress). Another land-based  adaptation of seed plants is pollen dispersed by wind or animals. The dis�  persal of pollen, in addition to dispersal of seeds, promotes genetic recom�  bination and distribution of the species over a wide geographic area.</p><p>New York, N.Y., U.S.) U.S. folk</p><p>Seeger, Pete(r) (b.

The main  part of the Zohar provides a mystical and symbolic interpretation of bib�  lical texts, especially the Torah, the book of Ruth, and the Song of  Solomon.

Segal began his artis�  tic career as an abstract painter. In 1958 he started creating sculptures from  chicken wire and plaster and two years later turned to plaster casts, often  using family members and friends as models. Though he was associated  with members of the burgeoning Pop art movement in the late 1950s,  Segal�s sculptures, which were frequently outfitted with the bland com�  mercial props of the Pop idiom, are distinguished from that characteris�  tically ironic movement by a mute, ghostly anguish. His casting technique,  in which the live model is wrapped in strips of plaster-soaked cheese�  cloth, imparts a rough texture and a minimum of surface detail to the fig�  ures, thus heightening the sense of anonymity and isolation.</p><p>Segesta \se-'jes-t9\ Ancient city, northwestern Sicily. Located near  modern Calatafimi, it was the chief city of the Elymi, a people of sup�  posedly Trojan origin (see Troy). Culturally, the city was Greek, but it  generally took the Carthaginian side against its Greek neighbours, and  boundary disputes with Selinus were frequent.

He worked</p><p>under Enrico Fermi before becoming director of the physics laboratory at  the University of Palermo in 1936. In 1937 he discovered technetium, the  first man-made element not found in nature. While visiting California in  1938, he was dismissed from the university by the fascist government. He  continued his research at the University of California at Berkeley, where  he and his associates discovered the element astatine and the isotope  plutonium-239, which he found to be fissionable. In 1955, using the new  Bevatron particle accelerator, Segre and Owen Chamberlain (b. 1920)  produced and identified antiprotons, antiparticles having the same mass  as protons but opposite electrical charge, setting the stage for the discov�  ery of many additional antiparticles. The two men shared a 1959 Nobel  Prize.</p><p>segregation, racial Practice of restricting people to certain circum�  scribed areas of residence or to separate institutions and facilities on the  basis of race or alleged race. Racial segregation provides a means of main�  taining the economic advantages and higher social status of politically  dominant races. Historically, various conquerors�among them Asian  Mongols, African Bantu, and American Aztecs�have practiced discrimi�  nation involving the segregation of subject races. Racial segregation has  appeared in all multiracial communities, except where racial amalgamation  has occurred on a large scale, as in Hawaii and Brazil. In such places there  has been occasional social discrimination but not legal segregation. In the  Southern states of the U.S., public facilities were segregated from the late  19th century into the 1950s (see Jim Crow law), and in South Africa a sys�  tem of apartheid sanctioned discrimination against nonwhites until it was  abolished in the 1990s. The U.S. civil rights movement and Civil Rights Act of  1 964 helped end racial segregation in education and public facilities,  though other forms of racial discrimination continued.</p><p>sei whale \'sa\ or Rudolphi's rorqual Vror-kwoA Swift species  (Balaenoptera borealis ) of baleen whale in the rorqual family. It is 40-50  ft (13-15 m) long and is bluish gray or blackish above and paler below.  It has small flippers, about 50 short lengthwise grooves on its chest, and  dark baleen with pale, silky, inner fringes. It inhabits oceans from the  Arctic to the Antarctic, migrating between cold and temperate summer  waters and winter breeding grounds in warmer regions.</p><p>Seifert Vsa-fert\, Jaroslav (b. Sept. 23, 1901, Prague, Bohemia,  Austria-Hungary�d. Jan. 10, 1986, Prague, Czech.) Czech poet. He made  a living as a journalist until 1950. Though his early works reflect youth�  ful expectations for the future of communism in the Soviet Union, he  broke with the Communist Party in 1929. More lyrical elements were evi�  dent in his later poems, and the history and current events of Czechoslo�  vakia were the most common subjects in his approximately 30 volumes.  In the 1980s and �90s many of his works were translated, including Hon�  eymoon Ride (1938), Bozena Nemcova�s Fan (1940), and Halley�s Comet  (1967). He also contributed to journals and wrote children�s literature and  memoirs. In 1984 he became the first Czech to win the Nobel Prize for  Literature.</p><p>seigniorage Ysan-ya-rij\ Charge over and above the expenses of coin�  age that is deducted from the bullion brought to a mint to be coined. From  early times, coinage was the prerogative of kings, who prescribed the  amount they were to receive as seigniorage. This was sometimes com�  pensated for by replacing part of the  gold or silver with base metal, result�  ing in debased coinage. In England  all such charges were abolished in  1666. Because coins are now issued  only as token money, they no longer  need to possess a high intrinsic  value, and low-standard silver or  base-metal alloys are sufficient. The  margin between the cost of produc�  ing a coin and its currency value is  known as seigniorage.</p><p>seignorialism See manorialism</p><p>Seine Vsen\ River ancient  Sequana Second longest river in  France.

April 29, 1954, Brooklyn, N.Y., U.S.) U.S. come�  dian and television actor. He initially worked as a stand-up comic in  nightclubs and on television. He cocreated and starred in the hit televi�  sion series Seinfeld (1990-98), which was inspired by his stand-up rou�  tines about life in New York City. One of the most successful situation  comedies, it featured a collection of selfish and neurotic characters  obsessed with the fear of commitment and the minutiae of everyday life.  He also starred in and was executive producer of Comedian (2002), a  documentary about his return to the comedy circuit.</p><p>seismic sea wave See tsunami</p><p>seismic Vslz-mik\ wave Vibration generated by an earthquake, explo�  sion, or similar phenomenon and propagated within the Earth or along its  surface. Earthquakes generate two principal types of waves: body waves,  which travel within the Earth, and surface waves, which travel along the  surface. Seismograms (recorded traces of the amplitude and frequency of  seismic waves) yield information about the Earth and its subsurface struc�  ture; artificially generated seismic waves are used in oil and gas pros�  pecting.</p><p>seismology \slz-'ma-l9-je\ Scientific discipline concerned with the  study of earthquakes and of the propagation of seismic waves. A branch of  geophysics, it has provided much information about the composition and  state of the planet�s interior. Recent work has focused on predicting earth�  quakes in hopes of minimizing the risk to humans. Seismologists have  also studied quakes induced by human activities�such as impounding  water behind high dams, injecting fluids into deep wells, and detonating  underground nuclear explosions�in an effort to find ways of controlling  natural earthquakes.</p><p>Seistan See Sistan  Seiyukai See Rikken Seiyukai</p><p>Sejanus \si-'ja-n3s\, Lucius Aelius (d. ad 31) Administrator of the  Roman empire for Tiberius.

After the suspicious death of  Tiberius�s son Drusus in 23, Sejanus sought to discredit Agrippina the  Elder, mother of Tiberius�s probable heirs. Forbidden to marry Drusus�s  widow, Sejanus moved the emperor to Capri (27) and had Agrippina and  her son Nero exiled (29).

Sejong oversaw the creation of hangul, the Korean  alphabet (see Korean language), and banned Buddhist monks from Seoul,  thereby reducing the power and wealth of the Buddhist hierarchy.</p><p>Seki Takakazu also called Seki Kowa (b. c. 1640, Fujioka,  Japan�d. Oct. 24, 1708, Edo) The most important figure of the wasan  (�Japanese calculation�) tradition that flourished from the early 17th cen�  tury until the opening of Japan to the West in the mid-19th century. He  was adopted at an early age by Seki Gorozaemon, a samurai official with  the Bureau of Supply in Edo, to carry on the Seki family name. He  assumed various positions as an examiner of accounts for the lord of Kofu,  Tokugawa Tsunashige (until 1678), and then his son, the future shogun  Tokugawa Ienobu (see Tokugawa period). Seki�s most productive research  was in algebra, a field in which he created powerful new tools and pro�  vided many definitive solutions. He was instrumental in recovering math�  ematical knowledge from ancient Chinese sources. He substituted a  tabular notational system for the cumbersome Chinese method of count�  ing rods, thereby simplifying the handling of equations with more than  one unknown.</p><p>Seku, Ahmadu See Ahmadu Seku  Selassie, Haile See Haile Selassie</p><p>Seldes Vsel-dosV George (b. Nov. 16, 1890, Alliance, N.J., U.S.�d.  July 2, 1995, Hartland Four Comers, Vt.) U.S. journalist. He became a  reporter in 1909. From 1918 to 1928 he worked for the Chicago Tribune,  then quit to pursue independent journalism. In You Can�t Print That (1928)  he criticized censorship and strictures on journalists, a continuing theme in  his career. He reported on the rise of fascism in Italy and Spain in the 1930s,</p><p>and he and his wife published In Fact, a journal devoted to press criticism,  in the years 1940-50. His other targets included the tobacco industry and J.  Edgar Hoover. He published his memoirs, Witness to a Century, in 1987.  His brother, the critic Gilbert Seldes (1893-1970), was managing editor of  The Dial during the 1920s. George Seldes�s best-known book was The  Seven Lively Arts (1924). He was a columnist for the New York Evening  Journal and the Saturday Evening Post, film critic for The New Republic,  first director of television for CBS News, and first dean of the University of  Pennsylvania�s Annenberg School for Communication.</p><p>selection In biology, the preferential survival and reproduction or pref�  erential elimination of individuals with certain genotypes, by means of natu�  ral or artificial controlling factors. The theory of evolution by natural  selection was proposed by Charles Darwin and Alfred Russel Wallace in  1858. Artificial selection differs from natural selection in that inherited  variations in a species are manipulated by humans through controlled breed�  ing in order to create qualities economically or aesthetically desirable to  humans, rather than useful to the organism in its natural environment.</p><p>Selene \so-'le-ne\ Latin Luna In Greek and Roman religion, the goddess  that personified the Moon. Her parents were the Titans Hyperion and  Theia; her siblings were Helios and Eos, the goddess of dawn. Selene fell  in love with Endymion, a handsome young shepherd; Zeus cast Endymion  into eternal sleep, but Selene visited him in the cave where he slept, and  he fathered her 50 daughters (one for each lunar month between Olym�  piads) and, according to some accounts, Narcissus. In art Selene is often  represented as a woman with the crescent moon on her head. As Luna she  had temples in Rome on the Aventine and Palatine hills.</p><p>Selenga \,si-liq-'ga\ River River, Mongolia and east-central Russia. It is  formed by the confluence of the Ider and Delger rivers and receives the  Orhon River at Suhbaatar. It continues north into Russia, eventually flowing  into Lake Baikal after a course of 920 mi (1,480 km). It is navigable from its  mouth to beyond Suhbaatar from May to October, when it is free of ice.</p><p>selenium \s9-'le-ne-9m\ Semimetallic chemical element, chemical sym�  bol Se, atomic number 34. It is widely distributed, usually in small  amounts, occasionally uncombined but more often as selenides of iron,  lead, silver, or copper. Selenium has several allotropes; the gray metallic  crystalline form is the most stable at room temperature. Its electrical con�  ductivity increases when light strikes it, and it can convert light directly  into electricity, so selenium is used in photocells (e.g., in light meters and  security alarms), solar cells, and photocopiers. It also has been used in rec�  tifiers to convert alternating to direct electric current. It serves as a red  colorant for glass and glazes. Selenium has valence 2, 4, and 6 in its com�  pounds, many of which are toxic though the element is not. Selenium  dioxide is an important reagent in organic chemistry. Vital to living cells,  it works as an antioxidant in the body and is being studied for a variety  of possible beneficial health effects; it is used in nutritional supplements  and animal feeds.</p><p>Seles Vse-losV Monica (b. Dec. 2, 1973, Novi Sad, Yugos.) Yugoslav-  U.S. tennis player. She went to the U.S. to train in 1985. She developed  quickly and became one of the dominant women stars of the 1990s,  achieving multiple wins in all grand-slam tournaments (French Open,  1990-92; Australian Open, 1991-93, 1996; U.S. Open, 1991-92) except  Wimbledon, which she lost in 1991 and 1992 to her rival Steffi Graf. In  1993 she stopped competing temporarily after being stabbed by a Graf  fan on a court in Hamburg, Ger.</p><p>Seleucia \sa-1u-sh3\ on the Tigris Ancient city, on the Tigris River,  central Iraq. Founded by Seleucus I Nicator in the late 4th century bc as  his eastern capital, it replaced Babylon as Mesopotamia�s leading city. The  population, which Pliny the Elder estimated at 600,000, was composed  largely of Macedonians and Greeks and also included Jews and Syrians.  During the Parthian domination of the Tigris-Euphrates valley that began  in the 2nd century bc, it maintained its position and trade despite its Greek  sympathies. In ad 165 the Romans burned the city, marking the end of  Hellenism in Mesopotamia. See also Seleucid dynasty.</p><p>Seleucid dynasty \s3-'lu-s3d\ Macedonian Greek dynasty (312-64  bc) founded by Seleucus I Nicator. Carved from the empire of Alexander  the Great, the Seleucid domain stretched from Thrace to the border of  India and included Babylonia, Syria, and Anatolia. Seleucus was suc�  ceeded in 281 by Antiochus I Soter, who reigned until 261. He was fol�  lowed by Antiochus II (r. 261-246), Seleucus II Calunicus (r. 246-225),  Seleucus III (r. 225-223), and Antiochus III (the Great; r. 223-187). Under</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Seleucus I Nicator &#x25BA; Selkirk I 1717</p><p>the last, the empire was at its height. Resistance to the power and spread  of Hellenistic culture soon began to manifest itself in the Asian lands.  Antiochus Ill�s encounter with the Romans signaled decline, especially  after the defeat of 190. The decline accelerated after the death of Antio�  chus IV (r. 175-164), who lost Judaea to the Maccabees. The efforts of  Demetrius I and Antiochus VII could not forestall the dynasty�s inevi�  table end at the hands of the Roman Pompey the Great in 64 bc.</p><p>Seleucus I Nicator \so- , lu-k9s...ni- , ka-t3r\ (b. c. 358, Europus,  Macedonia�d. August/September 281 bc, near Lysimachia, Thrace)  Macedonian army officer, founder of the Seleucid dynasty. After the death  of Alexander the Great, under whom he had served, Seleucus won an  empire centred on Syria and Iran. Having been ousted by Antigonus I  Monophthalmus and serving Ptolemy, Seleucus reconquered Babylon in  312. He declared himself king in 305. By 303 he had extended his empire  to India. In 301 he helped defeat Antigonus at the Battle of Ipsus and  received Syria, later taking southern Syria from Ptolemy. A marriage alli�  ance with Demetrius I Poliorcetes's daughter soured, and in 294, when his  son became sick with love for Seleucus�s wife (the son�s stepmother), he  gave her to him and made the son coregent. Hoping to reestablish Alex�  ander�s empire, Seleucus captured Demetrius (285) and defeated Lysima-  chus (281), another of Alexander�s former generals who had become a  satrap in Asia Minor. Later while attempting to enter Macedonia, he was  murdered.</p><p>Seleucus II Callinicus X.ka-b-'nI-kosN Latin "Gloriously Victori�  ous" (b. c. 265�d. 225 bc) Fourth king (r. 246-225) of the Seleucid  dynasty. He became ruler when his mother poisoned his father, Antiochus  II, and proclaimed him king. Her supporters made away with his Egyp�  tian stepmother, Bernice, daughter of Ptolemy II, whom Antiochus had  briefly married. Ptolemy III, Bernice�s brother, responded by invading  Seleucus�s kingdom and taking the eastern provinces. Seleucus managed  to regain northern Syria and part of Iran but was defeated by his brother  (c. 235), now supported by their mother, and ceded territory beyond the  Taurus River. He died in a fall from his horse.</p><p>self-defense In criminal law, an affirmative defense (e.g., to a murder  charge) alleging that the defendant used serious force necessarily for self�  protection. The claim of self-defense must normally rely on a reasonable  belief that the other party intended to inflict great bodily harm or death  and that avoidance by retreating was impossible. See also homicide.</p><p>Self-Defense Force Japan�s military after World War II. In Article 9  of Japan�s postwar constitution, the Japanese renounced war and pledged  never to maintain land, sea, or air forces. The rearming of Japan in the  1950s was therefore cast in terms of self-defense. In 1950 a small mili�  tary force called the National Police Reserve was created; this became the  National Safety Force in 1952 and the Self-Defense Force in 1954. Osten�  sibly it was never to be used outside Japan or its waters; consequently,  Self-Defense Force participation in UN peacekeeping missions or relief  work has sparked vigorous debate in Japan and abroad, especially among  nations that were victims of Japanese aggression in World War II.</p><p>self-determination Process by which a group of people, usually pos�  sessing a degree of political consciousness, form their own state and gov�  ernment. The idea evolved as a byproduct of nationalism. According to  the UN charter, a people has the right to form itself into a state or to oth�  erwise determine the form of its association with another state, and every  state has the right to choose its own political, economic, social, and cul�  tural systems. Moreover, the administering authorities of dependent ter�  ritories are enjoined to ensure political advancement and the development  of self-government in those territories.</p><p>self-esteem Sense of personal worth and ability that is fundamental to  an individual�s identity. Family relationships during childhood are  believed to play a crucial role in its development. Parents may foster self�  esteem by expressing affection and support for the child as well as by  helping the child set realistic goals for achievement instead of imposing  unreachably high standards. Karen Horney asserted that low self-esteem  leads to the development of a personality that excessively craves approval  and affection and exhibits an extreme desire for personal achievement.  According to Alfred Adler�s theory of personality, low self-esteem leads  people to strive to overcome their perceived inferiorities and to develop  strengths or talents in compensation.</p><p>self-fertilization Fusion of male and female sex cells (gametes) pro�  duced by the same individual. This type of fertilization occurs in bisexual</p><p>organisms, including most flowering plants, numerous protozoans, and  many invertebrates. Many organisms capable of self-fertilization can also  reproduce by means of cross-fertilization. As an evolutionary mechanism,  self-fertilization allows an isolated individual to create a local population  and stabilizes desirable genetic strains, but it fails to provide a significant  degree of variability within a population and thereby limits the possibili�  ties for adaptation to environmental change.</p><p>self-heal Perennial weed (Prunella vulgaris) in the MINT family, native  to North America and widespread throughout the continent. Growing  6-14 in. (14-36 cm) tall, self-heal is often a low weed in lawns. The  often-prostrate branches root readily wherever they touch soil. Tiny, two�  lipped, lilac-coloured or white flowers are clustered into noticeable dense,  spikes. Leaves have sparsely toothed or smooth margins. Regarded in  medieval times as a cure-all, the dried leaves and flowers are still brewed  for soothing sore throats.</p><p>self-incrimination In criminal law, the giving of evidence that might  tend to expose the witness to punishment for a crime. The term is gen�  erally used in relation to the privilege of refusing to give such evidence.  In some continental European countries (e.g., Germany), a person fear�  ing self-incrimination may make his own decision as to whether or not  he will testify. In Anglo-American practice, a person other than an accused  cannot refuse to testify; he may only cite his privilege against self�  incrimination, and the judge then decides whether he must testify. If  required to testify, he must answer all questions except those he consid�  ers to be self-incriminating. The Fifth Amendment to the U.S. Constitu�  tion contains a provision that protects a person from being compelled to  make self-incriminating statements, one intention being to prevent coer�  cion of testimony. See also rights of the accused; exclusionary rule.</p><p>Selim \se-'lem\ III (b. Dec. 24, 1761, Constantinople, Ottoman  Empire�d. July 29, 1808, Constan�  tinople) Ottoman sultan (r. 1789�</p><p>1807). He inherited the throne during  a losing war with Austria and Russia  (1787-92), with whom he later  signed treaties. Napoleon I�s inva�  sion of Egypt in 1798 drove him into  an alliance with Britain and Russia,  but, impressed with Napoleon�s suc�  cesses, he switched sides in 1806. At  home he attempted tax and land  reform and established a European-  style military corps, but, unable to  enforce his reforms in the face of  mutinies among the Janissaries and  other units, he rescinded them. He  was promptly overthrown and was  strangled on the orders of his succes�  sor, Mustafa IV.</p><p>Selin us \si-'li-n3s\ Ancient Greek  city, southern coast of Sicily.</p><p>Founded by Greek colonists in the  7th century bc, Selinus achieved great prosperity in the 5th century bc,  the time when its Doric temples were being built.

Its extensive ruins include the remains of eight temples.</p><p>Seljuq \'sel-jiik\ dynasty or Saljuq \'sal-juk\ dynasty (c. 11th�  13th centuries) Muslim Turkmen dynasty that ruled Persia, Iraq, Syria, and  Anatolia. Seljuq was the chief of a nomadic Turkish tribe. His grandsons  Chaghri Beg and Toghrjl Beg conquered realms in Iran. Under Alp-Arslan  and Malik-Shah, the empire came to include all of Iran, Mesopotamia,  Syria, and Palestine; Alp-Arslan�s victory over the Byzantine Empire at the  Battle of Manzikert led to several Crusades. Adherents of Sunnite Islam,  the Seljuqs adopted Persian culture, and under them the Persian language  partly displaced Arabic as a literary language in Iran. By 1200 Seljuq  power remained only in their sultanate of Rum in Anatolia, which col�  lapsed in a war against the Khwarezm-Shah dynasty in 1230 and was over�  run by Mongols in 1243.

He is best  known for staging plays and operas  for numerous international theatres  in settings far different than those  suggested by the text. His controver�  sial production of Ajax (1986) took  the form of a post-Vietnam military  trial, and among his many striking  opera productions, Wolfgang Ama�  deus Mozart�s Don Giovanni was  staged in an urban ghetto, his Cost  fan tutte in a diner, and his Marriage of Figaro in a corporate high-rise.</p><p>Sellers, Peter orig. Richard Henry Sellers (b. Sept. 8, 1925,  Southsea, Hampshire, Eng.�d. July 24, 1980, London) British film actor.  The son of vaudeville performers, he acted from childhood in his parents�  comedy act. In the early 1950s he performed on radio in the popular com�  edy series The Goon Show. He began appearing in the movies in the mid-  1950s; his performances in The Mouse That Roared (1959), I'm All Right,  Jack (1959), Lolita (1962), and Dr. Strangelove (1964), in which he  played three characters, were especially well received. He was enor�  mously popular as the bumbling Inspector Clouseau in the comedy The  Pink Panther (1964) and its sequels, and he later won acclaim for his role  as a simpleminded gardener in Being There (1979). His large range of  characters earned him international stardom at a time when rigid type�  casting was usual.</p><p>Selye Vzel-yoV Hans (Hugo Bruno) (b. Jan. 26, 1907, Vienna,  Austria-Hungary�d. Oct. 16, 1982, Montreal, Que., Can.) Austrian-born  Canadian endocrinologist. In early work on the effects of stress, he  injected ovarian hormones into rats; this stimulated the adrenal glands,  causing deterioration of the thymus gland, ulcers, and finally death. He  later showed that physical injury, environmental stress, and toxins could  have similar effects. Extending his theory to humans, he proved that a  stress-induced hormonal system breakdown could lead to so-called �dis�  eases of adaptation,� including heart disease and hypertension. He was  president of the International Institute of Stress and wrote 33 books,  including Stress Without Distress (1974).</p><p>Selznick, David O(liver) (b. May 10, 1902, Pittsburgh, Pa., U.S.�d.

Work�  ing for MGM, RKO, and other studios, he produced films such as Din�  ner at Eight (1933), King Kong (1933), David Copperfield (1935), and A  Tale of Two Cities (1935). He formed his own company, Selznick Inter�  national, in 1936 and produced hits such as A Star Is Born (1937). He was  essential to the enormous success of Gone with the Wind (1939), over�  seeing its entire production with detailed memos about every aspect of  the movie. He brought Alfred Hitchcock to the U.S. and produced Rebecca  (1940) and Spellbound (1945). He also produced Duel in the Sun (1946),  The Third Man (1949), and A Farewell to Arms (1957), which starred his  second wife, Jennifer Jones.</p><p>semantics Study of meaning, one of the major areas of linguistic study  (see linguistics). Linguists have approached it in a variety of ways. Mem�  bers of the school of interpretive semantics study the structures of lan�  guage independent of their conditions of use. In contrast, the advocates  of generative semantics insist that the meaning of sentences is a function  of their use. Still another group maintains that semantics will not advance  until theorists take into account the psychological questions of how people  form concepts and how these relate to word meanings.</p><p>semaphore Vse-mo-.forV Method of visual signaling, usually with flags  or lights. Before radio, a semaphore system was widely used to send mes�  sages between ships. A person would stand with arms extended, moving</p><p>two flags to specific angles to indicate letters or numbers. Before the  invention of the telegraph, semaphore signaling with lights on high tow�  ers was used to transmit messages between distant points; messages were  read by telescope. Modern semaphores have included movable arms or  rows of light simulating arms, displayed from towers and used to signal  railroad trains.</p><p>Semarang \s3-'mar-,aq\ City (pop., 1995 est.: 1,104,405), Java, Indo�  nesia.

He fought with  the Free French in World War II. After the war he worked as a docker in  Marseille and taught himself French. His writings, often on historical-  political themes, include The Black Docker (1956), God�s Bits of Wood  (1960), and Niiwam and Taaw (1987). About 1960 he became interested  in film; after studying in Moscow, he made films reflecting a strong social  commitment, including Black Girl (1966), the first feature produced in  sub-Saharan Africa. With Mandabi (1968), he began to film in the Wolof  language; his later films have included Xala (1974), Ceddo (1977), Camp  de Thiaroye (1987), and Guelwaar (1994).</p><p>Semele Vse-mo-.leV In Greek mythology, a daughter of Cadmus and Har-  monia, and the mother of Dionysus. When Semele became the lover of  Zeus, Hera was enraged, and she coaxed Semele into asking to see the god  in all his splendour. Having promised to grant Semele�s every wish, Zeus  was forced to comply. The thunderbolts emanating from him destroyed  Semele, but Zeus rescued the unborn Dionysus from the ashes. Some sto�  ries hold that Dionysus later descended into Hades and brought Semele  back to take her place among the immortals.</p><p>semen \'se-mon\ or seminal fluid Whitish viscous fluid emitted from  the male reproductive tract that contains sperm and liquids (seminal  plasma) that help keep them viable. Sperm cells, produced by the testes  in humans, represent 2-5% of semen volume; fluids from tubules, glands,  and storage areas of the reproductive system bathe them as they travel down,  nourishing them, keeping them motile, or participating in certain chemi�  cal reactions. During ejaculation, liquids from the prostate gland and semi�  nal vesicles dilute the sperm and provide a suitable, slightly alkaline  environment. An average ejaculation of a human male expels 0.1-0.3 cu  inches (2-5 ml), containing 200-300 million sperm.</p><p>Semey \,se-ma'\ formerly (until 1991) Semipalatinsk  V.se-me-po-'la-tinskV Port city (pop., 1999: 269,600) on the Irtysh (Ertis)  River, eastern Kazakhstan. It was founded as a Russian fort in 1718 and  was moved to its present site in 1778, at the junction of caravan trails;  before 1917 more than 11,000 camels passed through the city annually.  In the early 20th century it was connected by rail to Siberia and other  parts of Central Asia. It has one of the largest meat-packing plants in  Kazakhstan.

Unlike their near-contemporaries, the Pelagians  (see Pelagianism), the semi-Pelagians believed in the universality of origi�  nal sin as a corruptive force in mankind and held that it could not be over�  come without the grace of God. They endorsed baptism, but contrary to  Augustine, they taught that the innate corruption of mankind was not so  great that it was beyond the will of mankind to subdue through asceti�  cism. Its principal exponents were Sts. John Cassian (360-435), Vincent  of Lerins (died c. 450), and Faustus of Riez (c. 400-c. 490).</p><p>semiconductor Class of crystalline solids with electrical conductivity  between that of a conductor and an insulator.

Semiconductors are used in the manufacture of electronic devices such as  diodes, transistors, and integrated circuits. Intrinsic semiconductors have a  high degree of chemical purity, but their conductivity is poor. Extrinsic  semiconductors contain impurities that produce much greater conductiv�  ity.

In  the U.S. the term was formerly also used to refer to institutions of higher  learning for women, often teachers� colleges. Since at least the 4th cen�  tury there have been seminaries for the training of clergy. The first known  group of seminarians was gathered by St. Basil of Ancyra. The term  dropped out of general use in the Middle Ages, when most theological  training was in monasteries, and later, in the universities. After the Ref�  ormation and the emergence of new denominations, seminaries again  came into use, especially in the U.S. The 16th-century Council of Trent  ordered seminaries to be opened in every diocese.</p><p>Seminole Vse-mo-.nolX North American Indian people living mainly in  Florida and Oklahoma, U.S. Their language belongs to the Muskogean  language stock. The name Seminole is a Creek derivation of the Spanish  word cimarron , meaning �wild.� The Seminoles split off from the Creek  in the later 18th century and settled in northern Florida, where they were  joined by runaway slaves, Indian and black, from Georgia. They lived  more by hunting and fishing than by agriculture, constructed shelters of  thatched roofs supported by poles, and wore tailored hide clothing deco�  rated in bright-coloured strips. In an effort to stem white encroachment,  they fought a succession of wars (see Seminole Wars). Together the Semi�  nole number about 15,000.</p><p>Seminole Wars (1817-18, 1835-42, 1855-58) Three conflicts  between the U.S. and the Seminole Indians of Florida. The first began when  U.S. authorities tried to recapture runaway slaves living among Seminole  bands. After U.S. forces seized Spanish-held Pensacola and St. Marks,  Spain ceded its Florida territory under the Transcontinental Treaty (1819).  The second conflict followed the refusal of most Seminoles to relocate  under the Indian Removal Act. Led by Osceola, the Seminole warriors hid  in the Everglades and used guerrilla tactics to defend their land; about  2,000 U.S. soldiers were killed in the prolonged fighting. After Osceola  was captured, resistance declined and most Seminoles agreed to emigrate  west. The third conflict arose from efforts to oust the remaining Semi�  noles from Florida.</p><p>semiotics \,se-me-'a-tiks, ,se-me-'a-tiks\ or semiology Study of signs  and sign-using behaviour, especially in language. In the late 19th and early  20th century the work of Ferdinand de Saussure and Charles Sanders Peirce  led to the emergence of semiotics as a method for examining phenomena  in different fields, including aesthetics, anthropology, communications,  psychology, and semantics. Interest in the structure behind the use of par�  ticular signs links semiotics with the methods of structuralism. Saussure� s  theories are also fundamental to poststructurausm.</p><p>Semipalatinsk See Semey</p><p>Semite Person speaking one of a group of related languages, presum�  ably derived from a common language, Semitic (see Semitic languages).  The term came to include Arabs, Akkadians, Canaanites, some Ethiopi�  ans, and Aramaean tribes including Hebrews. Semitic tribes migrated from  the Arabian Peninsula, beginning c. 2500 bc, to the Mediterranean coast,  Mesopotamia, and the Nile River delta. In Phoenicia, they became seafar�  ers. In Mesopotamia, they blended with the civilization of Sumer. The  Hebrews settled at last with other Semites in Palestine.</p><p>Semitic Xso-'mi-tikX languages Family of Afro-Asiatic languages spo�  ken in northern Africa and South Asia. No other language family has been  attested in writing over a greater time span�from the late 3rd millennium  bc to the present. Both traditional and some recent classifications divide the  family into an eastern and western group. Until recently the sole known  East Semitic language was Akkadian; now some scholars add Eblaite, the  language of a cuneiform archive found at the ancient city of Ebla, with docu�  ments dating from c. 2300-2250 bc. West Semitic contains as one major  subgroup Northwest Semitic, which includes Ugaritic, known from alpha�  betic cuneiform texts of c. 1400-1190 bc; the closely related Canaanite lan�  guages (including Moabite, Phoenician, and Ancient Hebrew); and Aramaic.  Further subgrouping is controversial; traditionally, Arabic was placed in a  distinct South Semitic subgroup of West Semitic, though a more recent  classification puts it together with Northwest Semitic. The South Semitic  languages include Epigraphic South Arabian; Modern South Arabian (or  Modern South Arabic), a group of six languages spoken in eastern Yemen,  southwestern Oman, and the island of Socotra; and Ethiopic.</p><p>Semliki \'sem-le-ke\ River River, east-central Africa.

As an assistant at Vienna�s obstetric clinic at a time when death  rates from puerperal fever were as high as 30% in European maternity  hospitals, Semmelweis noticed that far fewer women died in the mid�  wives� division of the clinic than in the division where students (often  coming from the dissecting room) were taught. Concluding that students  carried the infection, he had them wash their hands in chlorinated lime  before each exam, and mortality dropped from 18% to 1%. Though his  ideas were accepted in Hungary, his Etiology, Understanding, and Pre�  venting of Childbed Fever (1861) was widely rejected abroad, including  by Rudolf Virchow.</p><p>Semmes \'semz\, Raphael (b.

A resident of Alabama, he resigned his commission  in 1861 and was appointed a commander in the Confederate navy. He  captured 17 Union merchant ships before assuming command of the  English-made Alabama in 1862. On numerous raids he captured, sank, or  burned 82 Union ships, disrupting Union commerce. In 1864 he was  defeated in a battle with the Union ship Kearsarge in the English Chan�  nel, but he escaped capture. After the war he practiced law.

Sen is best known for his work  on the causes of famine, and his research led to the development of solu�  tions for limiting the effects of food shortages. After attending Presidency  College in Calcutta (now Kolkata), Sen studied at Trinity College, Uni�  versity of Cambridge (B.A., 1955; M.A. and Ph.D., 1959). He taught eco�  nomics at the Universities of Jadavpur (1956-58) and Delhi (1963-71),  the London School of Economics, the University of London (1971-77),  the University of Oxford (1977-88), and Harvard University (1988-98).  In 1998 he was appointed master of Trinity College. His Poverty and  Famines: An Essay on Entitlement and Deprivation (1981) showed that  declining wages, unemployment, rising food prices, and inefficient food  distribution could lead to starvation. His views encouraged policy mak�  ers to maintain stable prices for food.</p><p>Senate In ancient Rome, the governing and advisory council that was  the most permanent element in the Roman constitution. Under the mon�  archy it served as an advisory council, with undefined powers. During the  republic it advised the consuls and supposedly stood second to them in  power. Senators were appointed by the consuls, but since they served for  life, by the late republic the Senate became independent of the consuls,  with extensive powers. About 312 bc the selection of senators was trans�  ferred from the consuls to the censors. In 81 bc Sulla made selection auto�  matic, routinely admitting all former quaestors.

Historically, fami�  lies linked by maternal kinship lived together in longhouses. Each com�  munity had a council of adult males, which guided the village chief. In  the autumn small parties would leave the villages for the annual hunt,  returning about midwinter; spring was the fishing season. Seneca women  cultivated corn and other vegetables. Warfare with other Indian nations  was frequent. In the American Revolution the Seneca were British allies,  resulting in the destruction of their villages by Gen. John Sullivan in 1779.  In 1797 they secured land for 12 reservations in western New York, four  of which still exist. Today the Seneca number about 5,500.

Agriculture is the  main industry; peanuts are the most impor�  tant cash and export crop. Other important  industries are fishing, mining, manufacturing, and tourism. Senegal has  large reserves of phosphates and iron ore. It is a republic with one leg�  islative house; its head of state and government is the president, assisted  by the prime minister. Links between the peoples of Senegal and North  Africa were established in the early centuries ad. Islam was introduced  in the 11th century, although animism retained a hold on the country into  the 19th century. The Portuguese explored the coast about 1444, and in  1638 the French established a trading post at the mouth of the Senegal  River. Throughout the 17th and 18th centuries, Europeans exported slaves,  ivory, and gold from Senegal. The French gained control over the coast  in the early 19th century and moved inland, checking the expansion of  the Tukulor empire; in 1895 Senegal became part of French West Africa.  Its inhabitants were made French citizens in 1946, and it became an over�  seas territory of France. It voted for a degree of autonomy in 1958, was  federated with Mali in 1959-60, and became an independent state in 1960.  In 1982 it entered a confederation with Gambia, called Senegambia, which  was dissolved in 1989.

Obligatory seppuku was a method of capital  punishment for a samurai, who would be beheaded by a second once he  had made an initial stab wound himself. Obligatory seppuku was abol�  ished in 1873, but voluntary seppuku continued to occur. Notable 20th-  century examples included those of army officer Nogi Maresuke and writer  Yukio Mishima.

The attacks were planned well in  advance; the militants�most of whom were from Saudi Arabia�traveled  to the U.S. beforehand, where a number received commercial flight train�  ing. Working in small groups, the hijackers boarded 4 domestic airliners  in groups of 5 (a 20th participant was alleged) on Sept. 11, 2001, and took  control of the planes soon after takeoff. At 8:46 am (local time), the ter�  rorists piloted the first plane into the north tower of the World Trade Cen�  ter in New York City. A second plane struck the south tower some 15  minutes later. Both structures erupted in flames and, badly damaged, soon  collapsed. A third plane struck the southwest side of the Pentagon near  Washington, D.C., at 9:40, and within the next hour the fourth crashed  in Pennsylvania after its passengers�aware of events via cellular  telephone�attempted to overpower their assailants. Some 2,750 people  were killed in New York, 184 at the Pentagon, and 40 in Pennsylvania.  All 19 terrorists died.</p><p>septic arthritis Acute inflammation of one or more joints caused by  infection. Suppurative arthritis may follow certain bacterial infections;  joints become swollen, hot, sore, and filled with pus, which erodes their  cartilage, causing permanent damage if not promptly treated by giving  antibiotics, draining the pus, and resting the joint. Nonsuppurative arthri�  tis can accompany several diseases caused by bacteria, viruses, or fungi;  joints become stiff, swollen, and painful to move. Treatment includes rest,  drugs, and, in the case of tuberculosis, orthopedic care to prevent skeletal  deformity.</p><p>septicemia \,sep-ti-'se-me-3\ or blood poisoning Invasion of the  bloodstream, after surgery or infectious disease, by microorganisms�  typically gram-negative (see gram stain) bacteria �and the toxins they  release. The latter trigger immune responses and widespread coagulation  in blood vessels. High fever, chills, weakness, and sweating are followed  by a drop in blood pressure. Multiple infections are often present, requiring  broad-spectrum antibiotics as well as drainage of foci of infection. Without  immediate treatment, septic shock follows, with a mortality rate over 50%.  Invasive technology and antibiotic-resistant bacteria in hospitals have  made septicemia more severe and more common. See also bacteremia.</p><p>Septimania \,sep-t3-'ma-ne-3\ Ancient territory, southwestern France.  Located between the Garonne and Rhone rivers and the Pyrenees and  Cevennes mountains, Septimania was settled during the reign of the  Roman emperor Augustus by veterans of the Seventh Legion (Septimani).  It was the last Gallic holding of the Visigoths of Spain. The region was  occupied by the Franks (732-768), was then part of the kingdom of  Aquitaine under the Carolingians, and became a separate duchy in 817.  Later in the 9th century it was subsumed under the counts of Toulouse.</p><p>Septuagint \sep-'tti-3-j9nt\ Earliest extant Greek translation of the  Hebrew scriptures from the original Hebrew, presumably made for the use  of the Jewish community in Egypt when Greek was the lingua franca. The  Pentateuch was translated near the middle of the 3rd century bc; the rest of  the Hebrew scriptures were translated in the 2nd century bc. The name Sep�  tuagint was derived from a legend that 72 translators worked on the project.  Its influence was far-reaching. The Septuagint rather than the original  Hebrew Bible was the main basis for the Old Latin, Coptic, Ethiopic,  Armenian, Georgian, Slavonic, and some Arabic translations of the Bible.</p><p>sequencing Determining of the order of amino acids in a protein or of  nucleotides in a nucleic acid or gene. The results have increased under�  standing of the mechanisms of life processes and have numerous appli�  cations. Whereas Frederick Sanger required 10 years to determine the  structure and sequence of amino acids in insulin and about as long to  determine the sequence of nucleotides in the DNA of a small virus, auto�  mated laboratory instruments and techniques can now do either task in  days or hours. See also genetic code; polymerase chain reaction.</p><p>sequestration In law, a writ authorizing a law-enforcement official to  take into custody the property of a defendant in order to enforce a judg�  ment or to preserve the property until a judgment is rendered. In some  civil-law jurisdictions, contested property may be deposited with a third  party until it is determined to whom it properly belongs.</p><p>sequoia See redwood</p><p>sequoia, giant See big tree</p><p>Sequoia National Park National park. Sierra Nevada range, Cali�  fornia, U.S. The park, with an area of 629 sq mi (1,629 sq km), was set  aside in 1890 to protect groves of big trees (Sequoiadendron giganteum)  that are among the world�s largest and oldest living things. The largest  tree in the park is thought to be 2,300-2,700 years old. Kings Canyon  National Park adjoins Sequoia park to the north; Mount Whitney is on the  eastern boundary.</p><p>Sequoyah or Sequoya or Sequoia \si-'kwoi-3\ (b. c. 1760/1770,  Taskigi, North Carolina colony�d. August 1843, near San Fernando,  Mex.) Creator of the Cherokee writing system. Sequoyah was probably  the son of a British trader. Convinced that the secret of the white people�s  power was written language, Sequoyah set about developing a Cherokee  system. Adapting letters from English, Greek, and Hebrew, he created a  system of 86 symbols representing all the syllables of the Cherokee lan�  guage. Most Cherokee quickly became literate as a result. Sequoyah never  learned to speak, read, or write English.</p><p>Seram See Ceram</p><p>seraph Vser-9f\ In Jewish, Christian, and Islamic literature, a celestial  being with two or three pairs of wings who guards the throne of God. In  Christian angelology, seraphim are the highest-ranking in the hierarchy of  angels. In art they are often painted red, symbolizing fire. They appear in  the Old Testament in a vision of Isaiah as six-winged creatures praising  God. See also cherub.</p><p>Serbia Vs3r-be-,ya\ Constituent republic of Serbia and Montenegro, con�  stituting about 80% of its area. The formerly autonomous provinces of  Kosovo (administered by the UN since 1999) and the Vojvodina are within  its borders. Area: 34,116 sq mi (88,361 sq km). Population (2001 est.):  9,993,000. The capital is Belgrade. Serbia is mountainous, with forests in  the central area and low-lying plains in the north. Serbs settled the region  in the 6th-7th centuries ad. In the 9th century the Serbs, nominally under  Byzantine suzerainty, converted to Eastern Orthodox Christianity. The  Ottoman Empire triumphed at the Battle of Kosovo in 1389; after a long  period of resistance, Serbia became part of the empire in 1459. After the  Russo-Turkish War of 1828-29, Serbia became an autonomous principal�  ity under Ottoman suzerainty and Russian protection. It became com�  pletely independent of the Ottoman Empire in 1878. After World War I,  Serbia became part of the Kingdom of Serbs, Croats, and Slovenes, which  was renamed Yugoslavia in 1929. In 1946 Serbia was made one of six  federated republics of Yugoslavia. As the Yugoslav economy faltered in  the 1980s, the country began to break apart. After an unsuccessful attempt  to prevent Slovenia�s secession in 1991, Serbian elements of the Yugo�  slav armed forces began assisting Bosnian Serbs in sweeping Bosniacs  (formerly designated Muslims) and Croats from eastern and northern Bos�  nia and Herzegovina. In 1992, after Yugoslavia�s breakup, Serbia joined  with Montenegro to form a new Yugoslav federation. The area remained  in turmoil (see Bosnian conflict). The signing of the Dayton peace accords  in 1995 ultimately brought little relief. Slobodan Milosevic retained power  in Serbia through the end of the century, and the push for more autonomy  by Albanian Kosovars provoked another round of fighting in 1998-99 (see  Kosovo conflict). As the violence escalated, NATO responded with a  bombing campaign, which led to a peace accord in June 1999. A change  in the Yugoslav government late in 2000 brought reinstatement in the UN,  and in 2003, after the Montenegrin government threatened to declare  independence, the governments of the two constituent states agreed to  remain united under the name Serbia and Montenegro.</p><p>Serbia and Montenegro Federated country, west-central Balkans  region, southern Europe. It consists of two republics: Serbia and Montene�  gro. Area: 39,449 sq mi (102,173 sq km). Population (2005 est.):  9,960,000. Administrative centre: Belgrade. The population comprises Ser�  bian, Albanian, Montenegrin, Hungarian, and other ethnic groups. Lan�  guages: Serbian (Serbo-Croatian), Albanian. Religions: Christianity  (mostly Eastern Orthodox; also Roman Catholic), Islam. Currencies: Ser�  bian dinar (Serbia); euro (Montenegro).

Rivers include the  Danube, Ibar, Morava, Timis, and Tisza. The  country has oil, gas, coal, copper, lead, zinc,</p><p>and gold deposits. Its industries include machine building, metallurgy,  mining, electronics, and petroleum products, while its agricultural products  include com, wheat, potatoes, and fruit. The country is a federation with a  president and a unicameral legislature, but most power resides with the  governments of the two republics. The Kingdom of Serbs, Croats, and Slov�  enes was created after the collapse of Austria-Hungary at the end of World  War I. The country signed treaties with Czechoslovakia and Romania in  1920-21, marking the beginning of the Little Entente. In 1929 an absolute  monarchy was established, the country�s name was changed to Yugoslavia,  and it was divided without regard to ethnic boundaries. Axis powers  invaded Yugoslavia in 1941, and German, Italian, Hungarian, and Bulgar�  ian troops occupied it for the rest of World War II. In 1945 the Federal Peo�  ple�s Republic of Yugoslavia was established; it included the republics of  Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Serbia, and Slo�  venia. Its independent form of communism under the leadership of Josip  Broz Tito provoked the Soviet Union and led to its expulsion from the Com-  inform in 1948. Internal ethnic tensions flared up in the 1980s, causing  Yugoslavia to collapse. In 1991-92 independence was declared by Croatia,  Slovenia, Macedonia, and Bosnia and Herzegovina; the new Federal  Republic of Yugoslavia (containing roughly 45% of the population and  40% of the area of its predecessor) was proclaimed by Serbia and Mon�  tenegro. Still fueled by long-standing ethnic tensions, hostilities continued  into the 1990s (see Bosnian conflict; Kosovo conflict). In 2003, after rati�  fication of an accord by the governments of Serbia, Montenegro, and Yugo�  slavia, the country was renamed Serbia and Montenegro.</p><p>Serbo-Croatian language South Slavic language spoken by some  21 million people in Croatia, Bosnia and Herzegovina, and Serbia and  Montenegro. As the dominant language of pre-1991 Yugoslavia, it was  used or understood by most ethnic groups of the federation. The Central  Neo-Shtokavian dialect forms the basis for both Standard Serbian and  Standard Croatian. Historically, Serbia�s literary language was the Ser�  bian recension of Church Slavonic (see Old Church Slavonic language).  In the 19th century a new literary language based on colloquial Serbian  was successfully promulgated by Vuk Stefanovic Karadzic. Croatian writ�  ten in the Latin alphabet first appears in the mid-14th century. In the 19th  century the Zagreb-based Illyrian political movement, which aimed at a  union of all South Slavs, turned to the Central Neo-Shtokavian dialect as  the basis for a literary language that would unite Croatians and bring them  closer to their Slavic compatriots. The move toward a unified �Serbo-  Croatian� was supported by the politically unified Yugoslav kingdom</p><p>(1918-41) and communist Yugoslavia (1945-91). With the independence  of Bosnia and Herzegovina in 1992, a Bosnian form of the language was  recognized of necessity. Vocabulary and pronunciation differences exist  among the three but form no real barrier to communication. The Croats  and Bosnians use the Roman, or Latin, alphabet; the Serbs and Montene�  grins of present-day Serbia and Montenegro use Cyrillic. Most Bosnians,  Serbs, and Croats insist that their language is distinct from the others,  and, perhaps, from a political perspective this is understandable; but most  linguists consider Serbian, Croatian, and Bosnian a single language,  which has historically been called Serbo-Croatian.</p><p>Serbs, Croats \'kro-,ats\ / and Slovenes, Kingdom of Balkan  state formed in 1918 after World War I. It included the previously inde�  pendent kingdoms of Serbia and Montenegro and the southern Slavic ter�  ritories formerly subject to the Austro-Hungarian Empire, including  Dalmatia, CROATiA-Slavonia, Slovenia, and Bosnia and Herzegovina. The  kingdom was ruled by the Serbian Karadjordjevic dynasty. In 1929 King  Alexander I sought to combat local nationalisms by proclaiming a royal  dictatorship and renaming the state Yugoslavia.

An international tourist attraction, it is the only place in Africa  where vast land-animal migrations still take place. More than 35 species  of plains animals, more than 350 species of birds, and lions, leopards,  elephants, rhinoceroses, hippopotamuses, giraffes, and baboons inhabit  the park. Poaching is a major problem.</p><p>serfdom In medieval Europe, condition of a tenant farmer who was  bound to a hereditary plot of land and to the will of his landlord. Serfs  differed from slaves in that slaves could be bought and sold without ref�  erence to land, whereas serfs changed lords only when the land they  worked changed hands. From about the 2nd century ad, large privately  owned estates in the Roman Empire that had been worked by slaves were  broken up and given to peasant farmers. These farmers came to depend  on larger landowners for protection in turbulent times, and swearing fealty  to a proprietor became common practice. In 332 Constantine I established  serfdom legally by requiring tenant farmers to pay labour services to their  lords. As serfs, they could not marry, change occupations, or move with�  out the permission of their lords, to whom they were required to give a  major portion of their harvest. The development of centralized political  power, the labour shortage caused by the Black Death, and endemic peas�  ant uprisings in the 14th and 15th centuries led to the gradual emancipa�  tion of serfs in western Europe. In eastern Europe serfdom became more  entrenched during that period; the peasants of the Austro-Hungarian  Empire were freed in the late 18th century, and Russia�s serfs were freed  in 1861. See also feudalism.</p><p>serial Film presented in a series of episodes over several months. The  serials, usually adventure melodramas, probably developed from the  adventure stories published in monthly installments in magazines. The  first internationally popular serial, The Perils of Pauline (1914), starring  Pearl White, was followed by other serials such as The Hazards of Helen,  which ran for 119 episodes (1914-17). Serials focused on action  sequences, with cliff-hanging endings for each episode. They remained  popular with movie audiences, especially children, into the 1940s.</p><p>serial murder Unlawful homicide of at least two people, carried out  in a series over a period of time. Serial murder differs from mass murder,  in which several victims are murdered at the same time and place. Crimi�  nologists have distinguished between two types of serial murder: classic  serial murder, which usually involves stalking and is often sexually moti�  vated, and spree serial murder, which is usually motivated by thrill�  seeking. Cases of serial murder have been documented since ancient  times. The incidence of serial murder increased dramatically in the early  19th century, particularly in Europe, though this development has been  attributed to advances in crime detection and increased news coverage  rather than to an actual rise in the number of occurrences. From the late  19th century serial murderers received considerable attention in the press,  and their cases inspired numerous books and films. These accounts, how�  ever, tended to mislead the public by suggesting that serial murder is a  common phenomenon, when in fact it represented less than 2% of all  murders in the late 20th century.</p><p>serialism Use of an ordered set of pitches as the basis of a musical  composition. The terms 12-tone music and serialism, though not entirely</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1724 I serigraphy &#x25BA; Servetus</p><p>synonymous, are often used interchangeably. The serial method was  worked out by Arnold Schoenberg in the years 1916-23, though another  serial method was being devised simultaneously by Josef Matthias Hauer.  To Schoenberg, it represented the culmination of the growth of chromati�  cism in the late 19th and early 20th century. In an attempt to erase the  system of tonality, which he regarded as outworn but which frequently  asserted itself even in the music of composers who desired to transcend  it, Schoenberg�s original method stipulated (among several other require�  ments) that no note could be repeated before all 11 other notes of the  chromatic scale had been used. Serialism, a broader term than 12-tone  music, can be applied to the use of fewer than 12 tones. �Total serialism,�  a concept that arose in the late 1940s, attempts to organize not only the  12 pitches but also other elements such as rhythm, dynamics, register, and  instrumentation into ordered sets.</p><p>serigraphy See silkscreen</p><p>serine \'ser-,en\ One of the nonessential amino acids, found in substan�  tial concentrations (sometimes 5-10%) in many common proteins.

He made his debut at age 12 in Vienna, and from 1920 he was a  close associate of the conductor Adolf Busch, whose daughter he married  in 1935. He immigrated to the U.S. in 1939 and began teaching at the  Curtis Institute, of which he served as director (1968-75). In 1950 he and  Busch cofounded the Marlboro Music Festival in Vermont, which under  Serkin�s direction became the preeminent locus for chamber music in the  U.S. He was known for his highly intelligent and expressive but self-  effacing playing of the German-Austrian classics.

He wrote teleplays for series such  as Kraft Television Theater, Studio One, and Playhouse 90, including  Requiem for a Heavyweight (1956, Emmy Award). He created, narrated,  and was the main writer of the famous supernatural series The Twilight  Zone (1959-65) and narrated the similar series Night Gallery (1970-73).  He also wrote screenplays, often based on his television scripts, such as  Patterns (1956) and The Rack (1956). He was coauthor of The Planet of  the Apes (1968).</p><p>Sermon on the Mount Biblical collection of religious teachings and  ethical sayings attributed to Jesus, as reported in the Gospel of St. Mat�  thew. The sermon was addressed to disciples and a large crowd of listen�  ers to guide them in a life of discipline based on a new law of love, even  of enemies, as opposed to the old law of retribution. It is the source of  many familiar Christian homilies and oft-quoted passages from the Bible,  including the Beatitudes and the Lord's Prayer. The sermon is often  regarded as a blueprint for Christian life.</p><p>serotonin N.ser-o-'to-nonX Chemical (5-hydroxytryptamine, or 5-HT)  derived from the amino acid tryptophan. It occurs in brain and intestinal  tissue, platelets, and certain connective-tissue cells and is a component of  many animal venoms (e.g., wasp, toad). A strong stimulator of blood�  vessel constriction and a neurotransmitter, serotonin concentrates in cer�  tain brain areas, especially the midbrain and hypothalamus. Some cases of  depression are apparently caused by reduced amounts or activity of sero�  tonin in the brain; many antidepressants counteract that condition. Exces�  sive brain serotonin activity may cause migraine headaches and nausea. LSD  may act by inhibiting the action of serotonin.</p><p>serpentine Vsor-pan-.teM Any of a group of magnesium-rich silicate  minerals whose composition resembles Mg 3 Si 2 0 5 (OH)4. Serpentine gen�  erally occurs in three forms: as chrysotile, the most common variety of  asbestos; and as antigorite or lizardite, both of which are commonly mas�  sive and fine-grained. Named in allusion to its resemblance to a snake�s  skin, serpentine is usually grayish, white, or green but may be yellow or  green-blue. It takes a high polish and is sometimes used as an ornamen�  tal stone.</p><p>Serra Vser-o\, Junipero (b. Nov. 24, 1713, Petra, Majorca, Spain�d.

When Spain began its occupation of Alta California  (now California), he joined the expedition and in 1769 founded Mission  San Diego. From 1770 to 1782 he founded eight more missions in Cali�  fornia, thereby strengthening Spain�s control of the area. His work earned  him the title Apostle of California, and he was beatified in 1988.</p><p>Serra, Richard (b. Nov. 2, 1939, San Francisco, Calif., U.S.) U.S.  sculptor. He paid for his education at the University of California by  working in steel factories. From 1961 he studied with Josef Albers at Yale  University. He settled in New York City c. 1966 and began to experiment  with new materials. In 1967-68 he displayed a series of works entitled  Splashes, which were pieces of molten lead thrown against a wall in a  gallery; the resulting solidified lead could be seen as sculpture, although  Serra himself viewed the process of creation as more important than the  end result. In 1969-70 gravity became a major element of his work; the  Prop series consisted of huge plates of lead or steel leaning against each  other, supported only by their opposing weights. He is best known for his  enormous, sometimes controversial, outdoor pieces that interact with the  environment, particularly Tilted Arc, installed in New York�s Federal  Plaza in 1981 but removed in 1989.

The  proportion of the world economy devoted to services rose rapidly in the  20th century. In the U.S., the service sector accounted for more than half  the gross domestic product in 1929, two-thirds in 1978, and more than  three-quarters in 1993. As increases in automation facilitate productivity,  a smaller workforce is able to produce more goods, and the service func�  tions of distribution, management, finance, and sales become relatively  more important.</p><p>servitude In property law, a right by which property owned by one per�  son is subject to a specified use or enjoyment by another. Servitudes allow  people to create stable long-term arrangements for a wide variety of pur�  poses, including shared land uses; maintaining the character of a residen�  tial neighbourhood, commercial development, or historic property; and  financing infrastructure and common facilities. Modem European civil law  is derived from Roman law, which divides real servitudes into rural (those  owed by one estate to another) and urban (those established for conve�  nience). Rural servitudes include various rights of way; urban servitudes  include building rights in neighbouring properties, such as drainage and  encroachment rights, and rights to light, support, and view. See also ease�  ment.</p><p>servomechanism Device used to correct the performance of a mecha�  nism automatically, by means of error-sensing feedback. The term prop�  erly applies only to systems in which the feedback and error-correction  signals control mechanical position or velocity. Servomechanisms were  first used in military and marine navigation equipment. Today they are  used in automatic machine tools, satellite-tracking antennas, celestial�  tracking systems on telescopes, automatic navigation systems, and  antiaircraft-gun control systems. The design of servomechanisms is con�  sidered to be a branch of both robotics and cybernetics.</p><p>sesame Erect, annual plant ( Sesamum indicum ) of numerous types and  varieties in the family Pedaliaceae. It has been cultivated since antiquity  for its seeds, which are used as food and flavouring and yield a prized oil.  The hulled seeds, creamy or pearly white and tiny, have a mild, nutlike  aroma and taste. The whole seed is used extensively in the cuisines of the  Middle East and Asia. Sesame oil, noted for its stability and its resistance  to becoming rancid, is used as a salad or cooking oil, in shortening and  margarine, in the manufacture of soaps, pharmaceuticals, and lubricants,  and as an ingredient in cosmetics.</p><p>Sessions, Roger (Huntington) (b. Dec. 28, 1896, Brooklyn, N.Y.,  U.S.�d. March 16, 1985, Princeton, N.J.) U.S. composer. He attended  Harvard and Yale, lived in Italy and Germany (1925-33), and later taught  principally at Princeton University (1935�45, 1953-65). His early inter�  est in Neoclassicism was replaced c. 1953 by his adoption of serialism. His  works include the operas The Trial of Lucullus (1947) and Montezuma  (1963), incidental music to The Black Maskers (1923), eight symphonies,  a Concerto for Orchestra (1982, Pulitzer Prize), and the cantata When  Lilacs Last in the Door-yard Bloom�d (1970), as well as several widely  read books on music.</p><p>set In mathematics and logic, any collection of objects (elements), which  may be mathematical (e.g., numbers, functions) or not. The intuitive idea</p><p>of a set is probably even older than that of number. Members of a herd of  animals, for example, could be matched with stones in a sack without  members of either set actually being counted. The notion extends into the  infinite. For example, the set of integers from 1 to 100 is finite, whereas  the set of all integers is infinite. A set is commonly represented as a list  of all its members enclosed in braces. A set with no members is called an  empty, or null, set, and is denoted 0. Because an infinite set cannot be  listed, it is usually represented by a formula that generates its elements  when applied to the elements of the set of counting numbers. Thus, {2x  | x = 1,2,3,...} represents the set of positive even numbers (the vertical bar  means �such that�).</p><p>set theory Branch of mathematics that deals with the properties of sets.  It is most valuable as applied to other areas of mathematics, which bor�  row from and adapt its terminology and concepts. These include the opera�  tions of union (u), and intersection (n). The union of two sets is a set  containing all the elements of both sets, each listed once. The intersec�  tion is the set of all elements common to both original sets. Set theory is  useful in analyzing difficult concepts in mathematics and logic. It was  placed on a firm theoretical footing by Georg Cantor, who discovered the  value of clearly formulated sets in the analysis of problems in symbolic  logic and number theory.</p><p>setback In architecture, a steplike recession in the profile of a high-rise  building. Usually dictated by building codes to allow sunlight to reach  streets and lower floors, the building must take another step back from  the street for every specified added height interval. Without building set�  backs, many of New York City�s streets would be in constant shadow. In  the 1920s architects drew attention to their setbacks with decorative  devices�mosaics; Chinese, Mayan, or Greek motifs; or geometric  blocks�but later architects deemphasized them. The International Style  glass-wall skyscraper was typically built without intermittent setbacks,  but architects met zoning requirements by creating one huge setback at  ground level that created a plaza. The late 20th century saw a return to  decorative setbacks.</p><p>Seth or Set Ancient Egyptian god and patron of the 11th nome, or prov�  ince, of Upper Egypt. A trickster, he was a sky god, lord of the desert,  and master of storms, disorder, and warfare. He was the brother of Osiris,  whom he killed, and he was antagonistic to Horus, the child of Osiris�s  sister, Isis. Seth�s cult largely died out in the 1st millennium bc, and he  was gradually ousted from the Egyptian pantheon. He was later regarded  as entirely evil and identified as a god of the Persians and other invaders  of Egypt.</p><p>SETI in full search for extraterrestrial intelligence Ongoing  effort to seek intelligent extraterrestrial life. SETI focuses on receiving  and analyzing signals from space, particularly in the radio and visible-  light regions of the electromagnetic spectrum, looking for nonrandom pat�  terns likely to have been sent either deliberately or inadvertently by  technologically advanced beings. The first modem SETI search was  Project Ozma (I960), which made use of a radio telescope in Green Bank,  W.Va. SETI approaches include targeted searches, which typically con�  centrate on groups of nearby sunlike stars, and systematic surveys cov�  ering all directions. The value of SETI efforts has been controversial;  programs initiated by NASA in the 1970s were terminated by congres�  sional action in 1993. Subsequently, SETI researchers organized privately  funded programs�e.g., the targeted-search Project Phoenix in the U.S.  and the survey-type SERENDIP projects in the U.S. and Australia. See  also Drake equation.</p><p>Seti I (d. 1279 bc) Egyptian king of the 19th dynasty (r. 1290-79 bc).  His father, Ramses I, had reigned only two years, and it was Seti who was  the real founder of the greatness of the Ramessids. Seti did much to pro�  mote Egypt�s prosperity. He fortified the frontier, opened mines and quar�  ries, dug wells, and rebuilt temples and shrines; he continued work on the  great hall at Karnak and built a temple at Abydos decorated with reliefs  of great delicacy.</p><p>Seton \se-t�n.

Bom into an upper-class  family, she married William Magee Seton in 1794. In 1797 she founded  the Society for the Relief of Poor Widows with Small Children, and in  1803 she was herself left a widow with five children. After converting</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1726 I Seton &#x25BA; Seven Weeks'War</p><p>from Episcopalianism to Roman Catholicism in 1805, she opened a free  Catholic elementary school in Baltimore, Md., in 1809. In 1813 she  founded the Sisters of Charity, the first U.S. religious order, and she served  as its superior until her death. She is often considered the mother of the  parochial school system in the U.S.</p><p>Seton Vse-t 3 n\, Ernest Thompson orig. Ernest Evan Thompson  also called Ernest E.T. Seton or Ernest Seton-Thompson (b. Aug.  14, 1860, South Shields, Durham, Eng.�d. Oct. 23, 1946, Seton Village,  Santa Fe, N.M., U.S.) British-born U.S. naturalist and animal fiction  writer. Seton�s family emigrated to Canada from England in 1866. He  earned a living for a time as a wild-animal artist, and in 1898 he pub�  lished his most popular book, the story collection Wild Animals I Have  Known. Deeply concerned for the future of the North American prairie,  he fought to establish reservations for American Indians and parks for  endangered animals. In 1902 he founded the Woodcraft Indians to give  children opportunities for nature study. He chaired the committee that  established the Boy Scouts of America.</p><p>setter Any of three breeds derived from a medieval hunting dog that  would set (lie down) when it found  birds so that it and the birds could be  covered with a net. Setters have long  hair on the ears, chest, legs, and tail.</p><p>They weigh 44-70 lbs (20-32 kg)  and stand 23-27 in. (58-69 cm). The  English setter, developed in the 15th  century, may be all white, black and  white-and-tan, or white with dark  flecks. The Gordon setter originated  in 17th-century Scotland; its soft,  wavy coat is black with tan mark�  ings. The Irish setter, bred in Ireland  in the 18th-cent, has a straight red  coat.</p><p>Settignano, Desiderio da See Desiderio da Settignano</p><p>settlement In law, a compromise or agreement between litigants to  settle the matters in dispute between them in order to dispose of and con�  clude their litigation. Generally, as a result of the settlement, prosecution  of the action is withdrawn or dismissed without any judgment being  entered. The parties may, however, incorporate the terms of the settle�  ment into a consent decree, recorded by the court. Most suits brought  today are either withdrawn or settled.</p><p>Settlement, Act of (June 12, 1701) Act of Parliament that thereafter  regulated the succession to the English throne. It decreed that if King  William III or Princess (later Queen) Anne died without issue, the crown  was to pass to James I�s granddaughter Sophie of Hanover (1630-1714)  and her Protestant heirs. The act resulted in the accession of the house of  Hanover in 1714. It also decreed that future monarchs must belong to the  Church of England, that judges were to hold office on the basis of good  behaviour rather than at the sovereign�s pleasure, and that impeachment  by the House of Commons was not subject to pardon by the sovereign.</p><p>settlement house or social settlement or community centre</p><p>Neighbourhood social-welfare agency. The staff of a settlement house  may sponsor clubs, classes, athletic teams, and interest groups; they may  employ such specialists as vocational counselors and caseworkers. The  settlement movement began with the founding of Toynbee Hall in Lon�  don in 1884 by Samuel Augustus Barnett (1844-1913). It spread to the  U.S. in the late 19th century with the establishment of such institutions  as Chicago�s Hull House (founded by Jane Addams). Many countries now  have similar institutions. In the late 19th and early 20th centuries, U.S.  settlement houses were active among the masses of new immigrants and  worked for reform legislation such as workers� compensation and child-  labour laws.</p><p>settling In building construction, the gradual subsiding of a structure as  the soil beneath its foundation consolidates under loading. This may con�  tinue for several years after the structure�s completion. Primary consoli�  dation occurs as water is squeezed out from the voids within the soil mass.  Secondary consolidation results from adjustments in the internal structure  of the soil mass under a sustained load. Whenever the possibility of settle�  ment exists, care must be taken to choose a structural system and foun�  dation capable of adapting. Fixed-end beams present a problem as they</p><p>are incapable of rotating under uneven settlement loads and bend in  response to the stress; simply supported beams, the ends of which act as  hinges, will rotate slightly and remain straight. Special columns with  jacking devices may then be used to level the beams. Floating founda�  tions and piles are often used to overcome the problems of building on  yielding soils. See also soil mechanics.</p><p>Seurat \sce-*ra\, Georges (-Pierre) (b. Dec. 2, 1859, Paris, Fr.�d.  March 29, 1891, Paris) French painter. He entered the Ecole des Beaux-  Arts in 1878 and exhibited at the 1883 Salon, though he had already lost  sympathy with its conservative policies. He studied scientific works in an  effort to achieve scientifically the colour effects that the Impressionists had  pursued, and developed Pointillism, the technique of juxtaposing tiny  brushstrokes of contrasting colours to portray the play of light. Employ�  ing this method, he created huge compositions, including his masterpiece,  Sunday Afternoon on the Island of La Grande Jatte (1884�86). He and  other artists working in this style became known as Neo-Impressionists. As  an aesthetic theorist, he explored the effects that could be achieved with  the three primary colours and their complements.</p><p>Seuss, Doctor See Theodor Geisel</p><p>Sevan \s9-�van\, Lake Lake, northern Armenia. It has an area of some  525 sq mi (1,360 sq km). Lying at 6,250 ft (1,905 m) above sea level in  a mountain-enclosed basin, it is Armenia�s largest lake and is in two con�  nected parts: the smaller Maly Sevan and the Bolshoy Sevan. It is rich in  fish. Several ancient Armenian churches lie along the shore.</p><p>Sevastopol formerly Sebastopol Vso-'vas-to-.poL Seaport city (pop.,  2001: 342,000) in the Crimea, southern Ukraine. In 1783 the Russians  annexed the Crimea, and, near the ancient Greek colony of Chersonesus,  they began construction of a naval base on Sevastopol Bay, an inlet of the  Black Sea. It became a commercial port in the early 19th century. It was  besieged by Anglo-French forces for 11 months (1854-55) during the  Crimean War, an ordeal chronicled by Leo Tolstoy in his Sevastopol  Sketches. The devastated town was later rebuilt, and it was the anti-  Bolshevik White Army headquarters in the Russian Civil War (1918-20).  In World War II it was destroyed after a months-long siege by the Ger�  mans, but again it was reconstructed. The chief base of the Russian Black  Sea fleet since the early 19th century, it has extensive dockyard facilities  and arsenals. The Ukrainian naval forces are also now based in Sevasto�  pol.</p><p>Seven, Group of Toronto-centred group of Canadian painters devoted  to landscape painting (especially of northern Ontario subjects) and the  creation of a national style. A number of future members met in 1913  while working as commercial artists in Toronto. The group adopted its  name on the occasion of a group exhibition held in 1920. The original  members included J.E.H. MacDonald, Lawren S. Harris, Arthur Lismer,  F.H. VaiTey, Franklin Carmichael, Frank H. Johnston, and Alexander  Young Jackson. The group was particularly influential in the 1920s and  �30s. In 1933 the name was changed to the Canadian Group of Painters.</p><p>Seven Cities of Cibola See Seven Cities of Cibola</p><p>Seven Days' Battles (June 25-July 1, 1862) American Civil War  battles that prevented Union capture of Richmond, Va. In a series of  attacks and counterattacks by both sides, the Confederate army under  Robert E. Lee forced Union troops under George B. McClellan to retreat  from a position 4 mi (6 km) east of the Confederate capital to a new base  on the James River. The Union failure to take Richmond and the with�  drawal of the Army of the Potomac ended the Peninsular Campaign.  Casualties were estimated at 16,000 for the Union and 20,000 for the  Confederates.</p><p>Seven Oaks Massacre (1816) Destruction of a Canadian fur-trading  settlement. Sixty Metis, directed by an agent of the North West Co.,  attempted to run provisions past the rival Hudson's Bay Co. settlement on  the Red River. They were intercepted by the colony�s governor and 25  soldiers at Seven Oaks, near the settlement. An argument grew into a fight  in which the Metis killed 20 men, including the governor. They then  threatened the remaining settlers with massacre, forcing them to abandon  the colony. The settlement was restored the next year.</p><p>Seven Weeks' War or Austro-Prussian War (June-August  1866) Conflict between Prussia on one side and Austria, Bavaria, Saxony,  Hanover, and minor German states on the other.

Included on the best known list were the Pyramids of Giza (the oldest  of the wonders and the only one substantially in existence today), the  Hanging Gardens of Babylon (a series of landscaped rooftop terraces on  a ziggurat, ascribed to either Nebuchadnezzar II or the semilegendary  Queen Sammu-ramat), the Statue of Zeus at Olympia (a large gold-and-  ivory figure of the god on his throne by Phidias), the Temple of Artemis  at Ephesus (a temple, built in 356 bc, famous for its imposing size and  the works of art that adorned it), the Mausoleum of Halicarnassus, the  Colossus of Rhodes, and the Pharos of Alexandria (a lighthouse built c.  280 bc on the island of Pharos off Alexandria, said to have been more  than 350 ft, or 110 m, high). These wonders inspired the compilation of  many other lists of seven attractions, or �wonders,� by later generations.</p><p>Seven Years' War (1756-63) Major European conflict between Aus�  tria and its allies France, Saxony, Sweden, and Russia on one side against  Prussia and its allies Hanover and Britain on the other. The war arose out  of Austria�s attempt to win back the rich province of Silesia, taken by  Prussia in the War of the Austrian Succession. Early victories by Frederick  II the Great in Saxony and Bohemia (1756-58) were offset by a decisive  Prussian defeat by Austria and Russia near Frankfurt (1759). After incon�  clusive fighting in 1760-61, Frederick concluded a peace with Russia  (1762) and drove the Austrians from Silesia. The war also involved the  overseas colonial struggles between Britain and France in North America  (see French and Indian War) and in India. The European conflict was  settled with the Treaty of Hubertusburg, by which Frederick confirmed  Prussia�s stature as a major European power.</p><p>Seventh-day Adventist See Adventist</p><p>Severn Vse-vomV River Welsh Hafren Vha-vren\ ancient Sabrina  River, eastern Wales and western England.

Named emperor by his troops, he marched on  Rome, entering the city without resistance. He effectively made Rome a  military monarchy, giving the army a dominant role in government, ignor�  ing the Senate, choosing officials from among the equites (see eques) and  granting control of the courts to the Praetorian prefect. He annexed Meso�  potamia, and he died attempting to subdue non-Roman Britain. He named  his son Caracalla his successor.</p><p>Severus Alexander in full Marcus Aurelius Severus Alex�  ander orig.

Severus�s mother and grandmother both held real power during his reign.  A council of senators gave nominal ruling power to the Senate. Civil law�  lessness reigned, and Severus�s military incompetence led to defeat by  the Persians, though their heavy losses forced them to withdraw from  Mesopotamia. When he bought peace from the invading Germanic Ale-  manni, his indignant soldiers murdered him and his mother.</p><p>Sevier \so-'vir\, John (b. Sept. 23, 1745, New Market, Va.�d.

In the American Revolution he helped  win the Battle of King�s Mountain (1780). He participated in a settlers�  revolt against North Carolina that formed the temporary state of Franklin  (1784) and was elected its governor (1785-88). He served in the U.S.  House of Representatives from North Carolina (1789-91). When Tennes�  see joined the Union, he served as its governor (1796-1801, 1803-09).</p><p>Sevigne \sa-ven-'ya.

Of old Burgundian nobility, she was well educated and  moved in court society in Paris after her marriage in 1644. She was  devoted to her children, and, after her daughter married and moved to  Provence, she began writing letters to her, without literary intention, that  recounted events, described people and details of daily life, and com�  mented on many topics. The stories and gossip in the 1,700 letters of this  correspondence, related in a natural, spontaneous tone, provide a vivid  picture of the 17th-century French aristocracy.</p><p>Sevilla \sa-'ve-ya\ English Seville \so-'vil\ ancient Hispalis City  (pop., 2005 est.: city, 704,154; 2001: urban agglom., 1,180,197), capital  of Sevilla province and Andalusia autonomous community ( comunidad  autonoma ), Spain. Located on the Guadalquivir River, it is Spain�s lead�  ing inland port and fourth largest city. Originally an Iberian town, Sevilla  prospered under the Romans in the 2nd century bc. In the 5th-8th cen�  turies ad it was the chief city in southern Spain under the Vandals and the  Visigoths. In 711 it fell to the Moors, and under Muslim rule it was a  cultural and commercial centre until the 13th century, when Spanish  Christians under Ferdinand III captured it. About 1500 Sevilla became  the centre of the Spanish colonial trade with the Americas. The French  occupied the city (1808-12), and during the Spanish Civil War (1936-39)  it was held by the Nationalists. It is one of Spain�s main tourist centres,  with historic mosques, cathedrals, and the 12th-century Alcazar Palace.  It was the site of the Iberoamerican Exposition in 1929 and the Univer�  sal Exposition in 1992. The University of Sevilla was founded in 1502.</p><p>Sevres VsevrA, Treaty of (Aug. 10, 1920) Pact at the end of World  War I between the Allied Powers and the government of Ottoman Tur�  key, signed at Sevres, France.

Sewer pipe  is laid following street patterns, and access holes with metal covers allow  periodic inspection and cleaning. Catch basins at street corners and along  street gutters collect surface runoff of storm water and direct it to the storm  sewers. Civil engineers determine the volume of sewage likely, the route  of the system, and the slope of the pipe to ensure an even flow by grav�  ity that will not leave solids behind. In flat regions, pumping stations are  sometimes needed. Modem sewage systems include domestic and indus�  trial sewers and storm sewers. Sewage treatment plants remove organic  matter from waste water through a series of steps. As sewage enters the  plant, large objects (such as wood and gravel) are screened out; grit and  sand are then removed by settling or screening with finer mesh. The  remaining sewage passes into primary sedimentation tanks where sus�  pended solids (sludge) settle out. The remaining sewage is aerated and  mixed with microorganisms to decompose organic matter. A secondary  sedimentation tank allows any remaining solids to settle out; the remain�  ing liquid effluent is discharged into a body of water. Sludge from the  sedimentation tanks may be disposed of in landfills, dumped at sea, used  as fertilizer, or decomposed further in heated tanks (digestion tanks) to  produce methane gas to power the treatment plant.</p><p>Sewall Vsii-olX, Samuel (b.

In 1692 he was appointed to pre�  side at the Salem witch trials, in which 19 people were executed. Later  admitting the error of the court�s decision, he stood silently in the Old  South Church in Boston in 1697 while his confession of error and guilt  was read aloud.

She was  introduced to writing by her mother, an author of juvenile best-sellers,  and her concern for the humane treatment of horses began early in life.  Confined to her house as an invalid, she spent her last years writing the  children�s classic Black Beauty (1877), a fictional autobiography of a  gentle, highbred horse. It had a strong moral purpose and is said to have  been instrumental in abolishing the cruel practice of using the checkrein  (a short rein used to prevent a horse from lowering its head).</p><p>sewing machine Machine for stitching material (such as cloth or  leather), usually having a needle and shuttle to carry thread and powered  by treadle or electricity. Invented by Elias Howe in 1846 and successfully  manufactured by Howe and Isaac Merritt Singer, it became the first widely  distributed mechanical home appliance and has also been an important  industrial machine. Modern sewing machines are usually powered by an  electric motor, but the foot-treadle machine is still in wide use in much  of the world.</p><p>sex Sum of features by which a member of a plant or animal species can  be placed into one of two complementary reproductive groups, male or  female. In both plants and animals, sex is determined by the reproductive  cells (gametes) produced by the organism. The male produces sperm cells,  and the female produces EGG cells. Males and females may or may not  have apparent structural differences, but they always have functional,  hormonal, and chromosomal differences. Patterns of behaviour, some�  times elaborate, may also distinguish the sexes in some species. See also  REPRODUCTIVE BEHAVIOUR.</p><p>sex chromosome Either of a pair of chromosomes that determine  whether an individual is male or female. The sex chromosomes of mam�  mals are designated X and Y; in humans, they constitute one pair of the  total 23 pairs of chromosomes. Individuals possessing two X chromo�  somes (XX) are female; those having one X and one Y chromosome (XY)  are male. The X chromosome is larger and carries more genetic informa�  tion than the Y. Traits controlled only by genes found on the X chromo�  some (e.g., hemophilia, red-green colour blindness) are said to be sex-  linked. Sex-linked traits occur far more frequently in males than in  females, since a male inheriting an allele for a recessive (see recessiveness)  trait on the X chromosome lacks a corresponding allele on the Y chro�  mosome that might counteract its effects. Several disorders are associated  with an abnormal number of sex chromosomes, including Turner syndrome  and Klinefelter syndrome.</p><p>sex linkage See linkage group</p><p>sextant Instrument for determining the angle between the horizon and  a celestial body�such as the Sun, the Moon, or a star�used in celestial  navigation to determine latitude and longitude. It consists of a metal arc,  marked in degrees, and a movable radial arm pivoted at the centre of the  arc�s circle. A telescope, mounted rigidly to the framework, is lined up  with the horizon. The radial arm, on which a mirror is mounted, is moved  until the star is reflected into a half-silvered mirror in line with the tele�  scope and appears, through the telescope, to coincide with the horizon.  The angular distance of the star above the horizon is then read from the  graduated arc of the sextant. From this angle, the latitude can be deter�  mined (within a few hundred metres) by means of published tables, and  by consulting an accurate chronometer the longitude can be established.  Invented in 1731, the sextant replaced the octant and became an essen�  tial tool of navigation.</p><p>Sexton, Anne orig. Anne Gray Harvey (b. Nov. 9, 1928, New�  ton, Mass., U.S.�d. Oct. 4, 1974, Weston, Mass.) U.S. poet. She worked  as a model, librarian, and teacher. Her first book of poetry, To Bedlam and  Part Way Back (1960), examines her mental breakdowns and subsequent  recoveries with confessional intensity. She continued probing her personal  life in All My Pretty Ones (1962) and Live or Die (1966, Pulitzer Prize).  Her other works include the nonfiction collection No Evil Star (1985).  She died a suicide. Several volumes of poetry were published posthu�  mously.</p><p>sexual dysfunction Inability to experience arousal or achieve sexual  satisfaction under ordinary circumstances, as a result of psychological or  physiological problems. The most common sexual dysfunctions have tra�  ditionally been referred to as impotence (applied to males) and frigidity  (females), but these terms have gradually been replaced by more specific  terms. Most sexual dysfunctions can be overcome through use of coun�  seling, psychotherapy, or drug therapy.</p><p>sexual harassment Unsolicited verbal or physical behaviour of a  sexual nature. Sexual harassment may embrace any sexually motivated  behaviour considered offensive by the recipient. Legal recourse is avail�  able in cases that occur in the workplace, though it is very difficult to  obtain convictions. In 1994 the Supreme Court of the United States ruled  that behaviour can be considered sexual harassment and an abridgment  of an individual�s civil rights if it creates a hostile and abusive working  environment.</p><p>sexual intercourse or coitus or copulation Act in which the male  reproductive organ enters the female reproductive tract (see reproductive  system). Various sexual activities (foreplay) lead to physiological changes  that progress to orgasm (climax) and resolution (see sexual response). If it  is completed, semen passes from the male into the female�s body. If con�  ditions favour fertilization, a sperm joins with an egg, and pregnancy begins  (see fertility; reproduction); contraception can prevent this. Intercourse with  an unwilling female is rape. See also reproductive behaviour; sexuality,  human; sexually transmitted disease.</p><p>sexual response Four-stage series of physiological reactions to  sexual stimulation. Persons do not necessarily progress through all four  stages, nor need two persons pass through them simultaneously. If the two  partners are of opposite sex, sexual response may lead to sexual inter�  course. In excitement, muscles tense and heart rate increases; in males,  the penis becomes erect; in females, the inner vagina widens, its walls  become moist, and the clitoris enlarges. In the plateau stage, breathing  accelerates and muscles continue tensing; the testes and glans of the penis</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>sexuality &#x25BA; Sforza I 1729</p><p>enlarge; the outer vagina contracts and the clitoris retracts. At orgasm the  muscle tension is quickly released; the penis contracts repeatedly, ejacu�  lating semen; the vagina contracts regularly. In resolution, the genitals of  both return to their pre-arousal condition; men cannot become aroused  for some minutes or hours; women can quickly become aroused again.</p><p>sexuality, human Tendencies and behaviour of human beings with  regard to any activity that causes or is otherwise associated with sexual  arousal. It is strongly influenced by the genetically inherited sexual  response patterns that ensure reproduction (see reproductive behaviour),  societal attitudes toward sex, and each individual�s upbringing. Physiol�  ogy sets only very broad limits on human sexuality; most of the enor�  mous variation found among humans results from learning and  conditioning. What is deviant in one society may be normal in another.  Sexuality covers gender identity, sexual orientation, and actual practices,  as well as one�s acceptance of these aspects of one�s personality, which  may be more important than their specifics. See also homosexuality; trans�  sexualism.</p><p>sexually transmitted disease (STD) Disease transmitted prima�  rily by direct sexual contact. STDs usually affect the reproductive system  and urinary system but can be spread to the mouth or rectum by oral or  anal sex. In later stages they may attack other organs and systems. The  best-known are syphilis, gonorrhea, AIDS, and herpes simplex. Yeast infec�  tions (see Candida) produce a thick, whitish vaginal discharge and genital  irritation and itch in women and sometimes irritation of the penis in men.  Crab louse infestation (see louse, human) can also be considered an STD.  The incidence of STDs has been affected by such factors as antibiotics,  birth-control methods, and changes in sexual behaviour.

The country has a develop�  ing economy that depends heavily on tourism. Exports include fish, copra,  and cinnamon. It is a republic with one legislative house; its head of state  and government is the president. The first recorded landing on uninhab�  ited Seychelles was made in 1609 by an expedition of the British East  India Company. The archipelago was claimed by the French in 1756 and  surrendered to the British in 1810. It became a British crown colony in  1903 and a republic within the Commonwealth in 1976. A one-party social�  ist state since 1979, it held multiparty elections in 1992 and adopted a  new constitution in 1993.</p><p>Seymour, Jane See Jane Seymour</p><p>Seyss-lnquart VzIs-'iqk-.vartV Arthur (b.

He served in the Austro-Hungarian army during  World War I and was seriously wounded. Later a lawyer in Vienna, he  became a leader of the moderate faction of the Austrian Nazis and served  on the federal council of state (1937-38). In response to German pres�  sure, he was named minister of interior and security and then replaced  Kurt von Schuschnigg as chancellor (1938). He welcomed the Anschluss  by Germany and became governor of the Austrian administration (1938�  39). In World War II he was German high commissioner of The Nether�  lands (1940-45) and carried out the Nazi policy against Dutch Jews. He  was tried at the Nurnberg trials and executed as a war criminal.</p><p>Sezession \za-tses-'yon\ Name for several groups of progressive artists  that broke away from established and conservative artists� organizations in  Austria and Germany. The first secession group was formed in Munich in  1892. It was followed by the Berlin Sezession movement, formed by Max  Liebermann in 1892, which included such artists as Lovis Corinth. The most  famous of the groups, formed in Vienna in 1897 by Gustav Klimt, favoured  a highly ornamental Art Nouveau style over the prevailing academicism.  Shortly thereafter, murals created by Klimt for the ceiling of the University  of Vienna auditorium were rejected as scandalous because of their erotic  symbolism. The Sezession movement influenced such artists and architects  as Egon Schiele and Josef Hoffmann.

Built on the site of two ancient settlements, the city  grew as an Islamic trading centre. It was occupied by the Normans in the  12th century and by the Spanish in the 16th century, and later served as  a stronghold of the Barbary Coast pirates. The town was bombarded by  the French in 1881 prior to their occupation of Tunisia and again in World  War II (1939-45), when it was a base for German forces until taken by  the British in 1943.

The second son of Francesco Sforza, he  was known as �the Moor� because of his dark complexion and black hair.  He plotted to take over as regent for his young nephew. He made Milan  supreme among the Italian states, and his patronage of scholars and art�  ists such as Leonardo da Vinci made his court renowned in Europe. He  bribed Maximilian I to declare him duke of Milan and fought to expel the  French from Italy. After Louis XII conquered Milan (1498), Ludovico tried  unsuccessfully to retake it (1500); he was captured and died in prison.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1730 I Sforza family &#x25BA; Shaftesbury</p><p>Sforza family Italian family that ruled Milan (1450-1535). The fam�  ily began with the prosperous farmer and later condottiere leader Muzio  Attendolo (1369-1424), who was given the nickname Sforza (�Force�).  His illegitimate son Francesco Sforza became duke of Milan in 1450.  Galeazzo Maria Sforza (1444-76) succeeded his father in 1466, and,  though a despotic ruler, he introduced the cultivation of rice, built canals  and encouraged commerce, and was a patron of the arts; he was assas�  sinated by conspirators who vainly hoped to provoke a popular uprising.  Gian Galeazzo Sforza (1469-94) succeeded his father in 1476 under the  regency of his mother and uncle, Ludovico Sforza, who usurped the gov�  ernment in 1481 and established Milan�s supremacy. After Ludovico was  driven from power by Louis XII of France in 1499, his son Massimiliano  Sforza (1493-1530) returned to rule briefly (1513-16) before yielding the  duchy to France. Another son, Francesco Maria Sforza (1495-1535),  returned after the French defeat to rule from 1522, until his death with�  out heirs ended the ducal line in 1535. The duchy then passed to Charles  V and the Habsburgs. Descendants of Sforza Secondo (an illegitimate son  of Francesco Sforza) became the Counts Sforza and included the diplo�  mat Carlo, Count Sforza.</p><p>SGML in full Standard Generalized Markup Language</p><p>Markup language for organizing and tagging elements of a document,  including headings, paragraphs, tables, and graphics.

It is bordered  by Shanxi, Henan, Hubei, Sichuan, and Gansu provinces, Chongqing  municipality, and Ningxia and Inner Mongolia autonomous regions. It has  an area of 75,600 sq mi (195,800 sq km). Its capital is Xi'an. Shaanxi has  three distinct natural regions: the mountainous southern region, the cen�  tral Wei River valley, and the northern upland plateau. The valley is espe�  cially vulnerable to earthquakes. Its northern parts were some of the  earliest settled in China, and the remains of ancient construction projects  found there include part of the Great Wall. From 221 bc until the Tang  dynasty, it was wealthy and the centre of much political activity. As its  irrigation system deteriorated, the area declined. In the 13th century, under  the Mongols, it assumed its present form as a province. Mao Zedong�s  Long March ended here in 1935. Its ancient irrigation system has been  rehabilitated in modern times, and the region is again a rich agricultural  area.

He studied the  mystical learning of the Kabbala and at age 22 proclaimed himself the  messiah. He traveled around the Levant, gaining both followers and  enemies. With the support of powerful religious and political figures, his  movement spread to parts of Europe and North Africa. In 1666, the year  he was prophesied to bring about fire restoration of Israel, he was impris�  oned by the Ottoman sultan and, under threat of torture, converted to Islam.

He served in the English Civil Wars, fighting first  for the king (1643) and then for Parliament (1644). He was appointed by  Oliver Cromwell to the council of state (1653-54, 1659) and also served  in Parliament (1654-60). One of 12 commissioners sent to invite Charles  II to return to England, he was appointed to Charles�s privy council (1660)  and served as chancellor of the Exchequer (1661-72) and lord chancel�  lor (1672-73). As head of the Council of Trade and Foreign Plantations  (1672-74), he drew up a constitution for the North American province of  Carolina, aided by his protege John Locke. Dismissed by Charles for sup�  porting the anti-Catholic Test Act and opposing the marriage of Charles�s  brother James (later James II) to another Catholic, Shaftesbury became a  leader of the Whig opposition. He exploited the political chaos caused by  Titus Oates to consolidate his parliamentary power and tried unsuccess�  fully to pass the Exclusion Bill, to keep James from the throne.

Derived from a branch of</p><p>the radical English Quakers (see Society of Friends), the movement was  brought to the U.S. in 1774 by Ann Lee, an illiterate textile worker whose  followers accepted her as the second incarnation of Christ. The Shakers  spread throughout New England from their base near Albany, N.Y., and  later into Kentucky, Ohio, and Indiana, eventually establishing 19 com�  munities. Communities held property in common, observed celibacy, and  pursued a life of productive labour. Although sometimes persecuted for  their pacifism and for bizarre beliefs falsely attributed to them, Shakers  won admiration for their model farms and orderly, prosperous communi�  ties. Their talent for simple, functional design led to numerous inventions  and innovations (see Shaker furniture). The movement reached its height  in the 1840s and thereafter gradually declined. In the early 21st century  only one working Shaker village remained: Sabbathday Lake, near New  Gloucester, Maine.</p><p>Shaker furniture Furniture designed for the religious colonies of  Shakers founded in the U.S. in the last quarter of the 18th century. The  Shakers� designs reflected their beliefs that good craftsmanship was in  itself an act of prayer and that form should follow function, an attitude  that anticipated the concept of Functionalism a century later. Constructed  of pine or other inexpensive wood, each item was fashioned solely to serve  its intended use and was devoid of decoration. Interest in Shaker furni�  ture and other Shaker crafts revived in the 20th century, after most Shaker  colonies had dissolved, and imitations are now widely produced.</p><p>Shakespeare, William (baptized April 26, 1564, Stratford-upon-  Avon, Warwickshire, Eng.�d.

He spent his early life in Stratford-upon-Avon, receiving at most  a grammar-school education, and at age 18 he married a local woman,  Anne Hathaway. By 1594 he was apparently a rising playwright in Lon�  don and an actor in a leading theatre company, the Lord Chamberlain's  Men (later King�s Men); the company performed at the Globe Theatre from  1599. The order in which his plays were written and performed is highly  uncertain. His earliest plays seem to date from the late 1580s to the mid-  1590s and include the comedies Love�s Labour�s Lost, The Comedy of  Errors, The Taming of the Shrew, and A Midsummer Night �s Dream ; his�  tory plays based on the lives of the English kings, including Henry VI  (parts 1, 2, and 3), Richard III, and Richard //; and the tragedy Romeo  and Juliet. The plays apparently written between 1596 and 1600 are  mostly comedies, including The Merchant of Venice, The Merry Wives of  Windsor, Much Ado About Nothing, and As You Like It, and histories,  including Henry IV (parts 1 and 2), Henry V, and Julius Caesar. Approxi�  mately between 1600 and 1607 he wrote the comedies Twelfth Night, All�s  Well That Ends Well, and Measure for Measure, as well as the great trag�  edies Hamlet (probably begun in 1599), Othello, Macbeth, and King Lear,  which mark the summit of his art. Among his later works (about 1607 to  1614) are the tragedies Antony and Cleopatra, Coriolanus, and Timon of  Athens, as well as the fantastical romances The Winter�s Tale and The  Tempest. He probably also is responsible for some sections of the plays  Edward III and The Two Noble Kinsmen.</p><p>Shakespeare�s plays, all of them written largely in iambic pentameter  verse, are marked by extraordinary poetry; vivid, subtle, and complex  characterizations; and a highly inventive use of English. His 154 sonnets,  published in 1609 but apparently written mostly in the 1590s, often  express strong feeling within an exquisitely controlled form. Shakespeare  retired to Stratford before 1610 and lived as a country gentleman until his  death. The first collected edition of his plays, or First Folio, was pub�  lished in 1623. As with most writers of the time, little is known about his  life and work, and other writers, particularly the 17th earl of Oxford, have  frequently been proposed as the actual authors of his plays and poems.</p><p>shakti or sakti Vsh9k-te\ In Hinduism, the �creative energy� inherent  in and proceeding from God. It is exemplified by the female principle, the  female reproductive organs, or the goddess Shakti, wife of Shiva. As  energy, shakti is viewed as the merging of powers emanating from male  gods, and it is possessed by each person. In Tantric Hinduism, the god�  dess Shakti is associated with the lowest of the chakras, lying dormant  within the body as a coiled serpent (Kundalini) that must be aroused to  reach spiritual liberation by uniting with Shiva at the top of the head. See  also Shaktism.</p><p>Shaktism or Saktism Vshok-.ti-zoirA Worship of the supreme Hindu  goddess Shakti.

Its  notes are produced by blowing across the open upper end, resulting in a  distinctively breathy tone. It has five fingerholes. The shakuhachi is of  great antiquity; it has been widely played as a solo instrument and in small  ensembles, especially with the koto and samisen (a fretless lute).</p><p>shale Any of a group of fine-grained, laminated sedimentary rocks con�  sisting of silt- and clay-sized particles. Shale constitutes roughly 60% of  the sedimentary rock in the Earth�s crust. Shales are commercially impor�  tant, particularly in the ceramics industry. They are a valuable raw mate�  rial for tile, brick, and pottery and constitute a major source of alumina  for portland cement. In addition, advances in recovery methods may one  day make oil shale a practical source for liquid petroleum.</p><p>shale oil Synthetic crude oil that is extracted from oil shale by pyroly�  sis, or destructive distillation. The oil obtained from oil shale cannot be  refined by the methods that have been developed for crude oil, however,  because shale oil is low in hydrogen and contains large amounts of nitro�  gen and sulfur compounds. To be made usable, shale oil must be hydro�  genated and then chemically treated to remove the nitrogen and sulfur, a  process too expensive to make shale oil commercially competitive with  crude oil. See also kerogen, petroleum.</p><p>shallot Mildly aromatic herbaceous plant {Allium ascalonicum) of the  lily family, probably of Asiatic origin, used to flavour foods. Closely related  to the onion and garlic, the shallot is a hardy perennial with short, small,  cylindrical, and hollow leaves; lavender to red flowers in a compact  umbel; and small, elongated, angular bulbs. Much like garlic, the bulbs  develop in clusters on a common base. The leaves are sometimes eaten  when green. The so-called shallot marketed extensively as green spring  onions is in fact a form of onion.</p><p>shaman Vsha-monX Person who uses magic to cure the sick, divine the  unknown, or control events. Both men and women can be shamans. Sha�  manism is classically associated with certain Arctic and Central Asian  peoples, but today the term is applied to analogous religious and quasi�  religious systems throughout the world. As medicine man and priest, the  shaman cures illnesses, directs communal sacrifices, and escorts the souls  of the dead to the other world. He operates by using techniques of ecstasy,  the power to leave his body at will during a trancelike state. In cultures  where shamanism occurs, sickness is usually thought of as soul loss; it is  thus the shaman�s task to enter the spirit world, capture the soul, and rein�  tegrate it in the body. A person becomes a shaman either by inheritance  or by self-election. See also animism.</p><p>Shamash \'sha-,mash\ In Mesopotamian religion, the god of the sun,  who, with his father, Sin, and the goddess Ishtar, was part of an astral triad  of divinities. As the solar god, Shamash was the heroic conqueror of night  and death, and he became known as the god of justice and equity. He was  said to have presented the Code of Hammurabi to the Babylonian king. At  night he served as judge of the underworld. The chief centres of his cult  were at Larsa and Sippar.</p><p>Shamil or Shamyl \ , sha-,mel\ (b. 1797?, Gimry, Dagestan�d. March  1871, Medina?, Arabia) Leader of Muslim Dagestan and Chechen moun�  taineers. In 1830 he joined a Sufi sect that had become involved in a holy  war against the Russians for Dagestan, formerly part of northern Iran but  occupied by the Russians from 1813. He eventually became imam of Dag�  estan and established an independent republic (1834), then led successive  raids against the Russians in the Caucasus for 25 years. Determined to  suppress him, the Russians attacked from all sides, compelling his sur�  render in 1859 and effectively ending Caucasian resistance to Russian  subjugation.</p><p>Shamir \sh3-'mer\, Yitzhak orig.

He  immigrated in 1935 to Palestine, where he helped found the Israel Free�  dom Fighters, later known as the Stem Gang. Twice arrested by British  authorities (1941, 1946), he twice escaped and eventually found asylum  in France. After Israel achieved independence, he served as a secret-  service operative until 1965. He was speaker of the Knesset (1977-80)</p><p>and later foreign minister under Menachem Begin (1980-83). He became  prime minister in 1983; in 1984 an indecisive election led to his sharing  power with the Labour Party leader Shimon Peres, and Shamir acted as  prime minister for the six years beginning in 1986, which included another  indecisive election in 1988 and the formation of a coalition government  in 1990, but lost power in 1992. He retired from the Knesset in 1996.</p><p>Sham'un, Kamil See Camille Chamoun</p><p>Shan Shan Tai Any member of a Southeast Asian people who live pri�  marily in eastern and northwestern Myanmar (Burma) and also in Yun�  nan province, China. The Shan are the largest minority group in Myanmar,  numbering more than four million. They live mainly in the valleys and  plains on the Shan Plateau, where they grow rice or practice shifting agri�  culture. They are Theravada Buddhists and have their own written lan�  guage and literature. They dominated much of Myanmar from the 13th  to the 16th century; since the 1970s they have been at odds with the  national government over the issue of local autonomy.

It lies on  the Yellow Sea and is bordered by Jiangsu, Anhui, Henan, and Hebei prov�  inces. It has an area of 59,200 sq mi (153,300 sq km), and its capital is  Jinan. It contains the Shandong Peninsula and an inland zone that includes  a fertile, intensely cultivated area that forms part of the Huang He (Yel�  low River) basin. The peninsula has been occupied since the 3rd millen�  nium bc, and by the 8th century bc it had become a centre of political and  military activity. It became northern China�s leading maritime centre in  the 3rd century ad and retained that position for centuries. In the 19th  century devastating floods resulted in substantial emigration. It came  under German, British, and Japanese influence in the late 19th century.  The Japanese occupied it in 1937-45; it came under communist control  in 1948. Its products include wheat, corn, iron ore, gold, fish, and silk.  Confucius and Mencius were born in Shandong.</p><p>Shandong Peninsula or Shan-tung Peninsula conventional  Shantung Peninsula Peninsula, eastern China. Occupying the east�  ern section of Shandong province, it extends northeastward between the  Bo Hai (Gulf of Chihli) and the Yellow Sea. The terrain is hilly, with eleva�  tions around 600 ft (180 m), rising to 3,707 ft (1,130 m) in the Lao Moun�  tains. Fishing is important along the coast, and fruit is grown in the hills.  Iron ore, magnesite, and gold are abundant. Some of China�s best ports  are located along the peninsula�s rocky, indented coast.</p><p>Shang dynasty or Yin dynasty Traditionally, the second of Chi�  na�s dynasties, following the Xia dynasty. Until excavations in the 20th  century provided archaeological evidence for the Xia, the Shang was the  first verifiable Chinese dynasty. Dates for its founding vary; traditionally  its rule was said to have spanned 1766-1122 bc, but more recently the  range has been given as c. 1600-1046 bc. Shang society was stratified: it  included a king, local governors, nobles, and the masses, who engaged  in agriculture. The Shang developed a 12-month, 360-day calendar with  intercalary months added as necessary. The Chinese writing system began  to develop; numerous records and ceremonial inscriptions survive. Sur�  viving artifacts include musical instruments, superb bronze vessels, pot�  tery for ceremonial and daily use, and jade and ivory ornaments. Cowrie  shells were used as currency.

The municipality, on the East China Sea, is bordered  by Jiangsu and Zhejiang provinces and has an area of 2,400 sq mi (6,200  sq km). The city is located on the Huangpu River, which gives oceango�  ing vessels access to it. The site was settled during the Bei (Northern)  Song period (ad 960-1127), and later under the Ming dynasty it was an  area of intense cotton production. This changed when it became the first  Chinese port opened to trade with the West after China�s defeat by Brit�  ain in the Opium Wars (1842); it came to dominate the nation�s commerce.  The site of the Chinese Communist Party�s founding in 1921, it saw severe  fighting in the Sino-Japanese War of 1937�45 and was occupied by Japan  during World War II. Since 1949, it has become China�s chief industrial  and commercial centre and one of its leading centres of higher education  and scientific research.</p><p>Shankar \'shaq-,kar\ / Ravi (b.

He is said to have trav�  eled all over India, holding discussions with philosophers of different  creeds, and is believed to have founded four monasteries. He is the reputed  author of more than 300 Sanskrit works, most of them commentaries on  and expositions of Vedic literature, but most are not regarded as authen�  tic. The most renowned exponent of the Advaita school of Vedanta phi�  losophy, he is credited with laying the foundation for Hindu orthodoxy  in India after centuries of challenge from Jainism and Buddhism.</p><p>Shannon, Claude (Elwood) (b.

It is bordered by  Hebei, Henan, and Shaanxi provinces and Inner Mongolia. It has an area  of 60,700 sq mi (157,100 sq km). The capital is Taiyuan. Largely a vast  plateau covered by great loess deposits, it was the home of early Chinese  agriculture. Most of the people are Han Chinese; other ethnic groups  include Hui (Chinese Muslims), Mongols, and Manchus. Since ancient  times it has been an integral part of the various northern kingdoms of  China, serving as a buffer against invaders from the north and as a key  trade route. It was one of the major avenues by which Buddhism came to  China from India. After the overthrow of the Qing dynasty in 1911-12,  the warlord Yan Xishan ruled as absolute dictator until the end of World  War II. Japan occupied part of the province during the Sino-Japanese War.  Communist forces assumed control of Shanxi in 1949.

Originally a Dao-  ist, he refused all offers of government office and lived in a hermitage  outside Henan. He became interested in Confucianism by studying the Yl  jing, from which he developed his theory that numbers are the basis of  all existence. He believed that the key to the world hinged on the num�  ber four; thus the universe is divided into four sections (sun, moon, stars,  zodiac), the body into four sense organs (eye, ear, nose, mouth), and the  earth into four substances (fire, water, earth, stone). He also introduced  to Confucianism the Buddhist concept of the universe�s repeating cycles.</p><p>shape-note singing U.S. a cappella singing style incorporating many  folk hymns and utilizing a special musical notation. The seven-note scale  used by some singers is sung not to the syllables do-re-mi-fa-sol-la-ti but  to a four-syllable system brought to America by early English colonists:  fa-sol-la-fa-sol-la-mi. The system reflects the fact that a series of three  intervals repeats itself in the major scale. A differently shaped note head  is used for each of the four syllables. The singer reads the music by fol�  lowing the shapes; singers unfamiliar with the system can read the notes  according to their placement on the staff. The tradition started in New</p><p>England and moved South and West as more sophisticated forms of music  reached the U.S. Shape-note singing had largely died out except in rural  areas by the 1880s, but it has experienced a revival in recent years. The  traditional shape-note hymnal, The Sacred Harp, first published in 1844,  remains in use today.</p><p>shaper Metal-cutting machine tool in which the workpiece is usually  held in a vise or similar device that is clamped to a table and can be manu�  ally operated or power-driven at right angles to the path of a chisel-like  cutting tool with only one cutting edge. A moving table feeds the work-  piece in small, individual steps at the end of each stroke of the tool. The  adjustable mounting of the tool permits the cutting of grooves and gen�  erating of surfaces at almost any angle to one another. The largest shapers  have a 36-in.

U.S. astronomer. In 1911 he began a determination  of the dimensions of the components of numerous binary stars from mea�  surements of their light variation when they eclipse one another; he also  proposed (correctly) that Cepheid variables are pulsating variable stars, not  eclipsing binaries (see eclipsing variable star). In 1914 he joined the staff  of Mount Wilson Observatory. His study of the distribution of globular  clusters in the Milky Way Galaxy led him to deduce that the Sun, previ�  ously thought to lie near the centre of the Galaxy, was 50,000 light-years  from the centre (now estimated at about 27,000), leading to the first real�  istic estimate of the Galaxy�s size. Shapley also studied neighbouring gal�  axies, especially the Magellanic Clouds, and found that galaxies tend to  occur in clusters.</p><p>shar-pei Vshar-'paX Ancient breed of dog that originated in China.

Throughout his career he sought  to avoid the extremism he saw in the various theological sects of Islam,  as well as in other Sufi orders; his aim was to take the best from each,  ignoring conflicts between them. Since his thoughts and writings were  unsystematic and confused, the appeal of his teachings depended largely  on his personal presence. The order gradually declined after his death,  though it remained popular until the 19th century.</p><p>Sharansky, Natan See Anatoly Shcharansky  sharecropping See tenant farming  Shari River See Chari River</p><p>Sharl'ah \'sha-'re-a\ Legal and moral code of Islam, systematized in the  early centuries of the Muslim era (8th-9th century ad).

Sharfah differs  fundamentally from Western law in that it purports to be grounded in  divine revelation. Among modem Muslim countries, Saudi Arabia and  Iran retain Sharfah as the law of the land, in both civil and criminal pro�  ceedings, but the legal codes of most other Muslim countries combine  elements of Islamic and Western law where necessary.

After moving to London in  1876, he worked for years as a music  and art critic, wrote book and theatre  reviews, and was an active member  of the socialist Fabian Society. In his  first play, Widowers� Houses (1892),  he emphasized social and economic  issues instead of romance, adopting  the ironic comedic tone that would  characterize all his work. He  described his first plays as �unpleas�  ant� because they forced the specta�  tor to face unpleasant facts; these  plays include Mrs. Warren�s Profes�  sion (1893), which concerns prosti�  tution and was barred from  performance until 1902. He then  wrote four �pleasant� plays, includ�  ing the comedies Arms and the Man (1894) and Candida (1895). His next  plays include Caesar and Cleopatra (1899) and Man and Superman  (1905). He used high comedy to explore society�s foibles in Major Bar�  bara (1905), The Doctor�s Dilemma (1911), and Pygmalion (1913), his  comedic masterpiece. Other notable plays include Androcles and the Lion  (1912), Heartbreak House (1919), and Saint Joan (1923). His other writ�  ings and speeches made him a controversial public figure for much of his  life. He received the Nobel Prize in 1925.</p><p>Shaw, Lemuel (b. Jan. 9, 1781, Barnstable, Mass., U.S.�d. March 30,  1861, Boston, Mass.) U.S. jurist. He was educated at Harvard University.  In 1822 he drafted the first municipal charter for Boston virtually with�  out precedents to guide him; it remained in effect until 1913. In 1830 he  was appointed chief justice of the Supreme Judicial Court of Massachu�  setts, where he served for 30 years. His rulings were formative in the  development of both Massachusetts and national jurisprudence. In par�  ticular, his ruling in favour of a striking labour union (1842) provided the  first major precedent for removing unions from the province of the law  of conspiracy, and his decision upholding the city�s segregated schools  (1849) was later reflected in the �separate but equal� doctrine propounded  by the Supreme Court of the United States in Plessy v. Ferguson (1896),  though it also led Massachusetts to pass the only 19th-century American  desegregation law. His daughter married Herman Melville.</p><p>shawm Double-reed Renaissance woodwind instrument, ancestor of the  oboe. Its conical bore and bell are wider than the oboe�s. A disk called a  pirouette usually supports the player�s lips. Shawms were constructed in  many sizes, from treble to great bass. They were in use in the Middle East  perhaps 2,000 years ago, and they were introduced into Europe during the  Crusades. With their powerful tone, shawms were classed with the �loud�  or �outdoor� instruments and were used in dance and ceremonial music.</p><p>Shawn, Ted orig. Edwin Myers Shawn (b.

After the  couple separated in 1931, the com�  pany disbanded, and Shawn estab�  lished a company of male dancers for  which he choreographed works that  embodied a vigorous, masculine  style. In 1933 he founded the Jacob�s  Pillow Dance Festival in Becket,</p><p>Mass., as a summer residence and  theatre for his dancers. He continued  to dance and choreograph into the  1960s.</p></section><section><p>Shawnee \sho-'ne\ Algonquian-  speaking North American Indian people from the central Ohio River valley.  (See Algonquian languages.) Closely related in language and culture to the  Fox, Kickapoo, and Sauk, the Shawnee were also influenced by the Seneca  and Delaware. In the summer the Shawnee lived in bark-covered houses  grouped into large villages near cornfields. Women farmed, and the pri�  mary male occupation was hunting. In winter the village broke into small  patrilineal family groups, which moved to hunting camps. In the 17th cen�  tury the Shawnee were driven from their home by the Iroquois, scattering  into widely separated areas. After 1725 the Shawnee reunited in Ohio. Fol�  lowing their defeat by Gen. Anthony Wayne (1794), they broke into three  independent branches that eventually settled in Oklahoma. Today some  11,000 people claim Shawnee ancestry.

In  a period of economic depression and land seizures for debt collection,  several hundred farmers led by Daniel Shays (17477-1825), who had  served as a captain in the Revolutionary army, marched on the state  supreme court in Springfield, preventing it from carrying out foreclosures  and debt collection. Shays then led about 1,200 men in an attack on the  nearby federal arsenal, but they were repulsed by troops under Benjamin  Lincoln. As a result of the uprising, the state enacted laws easing the eco�  nomic condition of debtors.</p><p>Shcharansky \sho-'ran-ske\, Anatoly (Borisovich) or Natan  Sharansky (b. Jan. 20, 1948, Stalino, Ukraine, U.S.S.R.) Soviet dissi�  dent and Israeli politician. He studied mathematics and computer program�  ming at the Moscow Physical-Technical Institute (1966-72) and then  worked in Moscow as a computer specialist for the Institute of Oil and Gas.  A Jew, he applied for permission to emigrate to Israel in 1973 but was  refused and discharged from his job. With an excellent command of  English, he became a spokesperson for the dissidents and refuseniks in con�  tacting Western correspondents to publicize their cause. In 1977 he was  arrested by the KGB for treason and espionage, sentenced to 13 years in  prison, and sent to the Siberian Gulag. His wife, Avital, who had emigrated  to Israel in 1974, championed his cause. Released in 1986, he settled in  Israel, where he founded a party stressing the concerns of Russian immi�  grants, and he was appointed to the cabinet as minister of industry and trade  in 1996. He later served as interior minister in Ehud Barak�s government  and as housing and construction minister in Ariel Sharon�s government.</p><p>She-Chi See She-Ji</p><p>She-Ji Vsho-'jeV or She-Chi Ancient Chinese compound deity of the  soil and harvests. China�s earliest legendary emperors worshiped She  (earth), for they alone had responsibility for the entire earth and country.  Since ordinary people had no part in this courtly worship, they came to  focus their worship on the god of grain (Ji). Local shrines held two images,  one of She and one of Ji, and eventually the two images were considered  man and wife.</p><p>shear legs Device, often temporary, for lifting heavy weights. It con�  sisted of three poles lashed together at the top with a block and tackle  attached. Shear legs were often used for placing masts in sailing ships.</p><p>shear wall In building construction, a rigid vertical diaphragm capable  of transferring lateral forces from exterior walls, floors, and roofs to the  ground foundation in a direction parallel to their planes. Examples are the  reinforced-concrete wall or vertical truss. Lateral forces caused by wind,  earthquake, and uneven settlement loads, in addition to the weight of</p><p>structure and occupants, create powerful twisting (torsional) forces. These  forces can literally tear (shear) a building apart. Reinforcing a frame by  attaching or placing a rigid wall inside it maintains the shape of the frame  and prevents rotation at the joints. Shear walls are especially important  in high-rise buildings subject to lateral wind and seismic forces.</p><p>shearing In textile manufacturing, the cutting of the raised nap of a pile  fabric to a uniform height to enhance appearance. Shearing machines  operate much like rotary lawn mowers, and the amount of shearing  depends on the desired height of the nap or pile. Shearing may also be  applied to create stripes and other patterns by varying surface height. In  animal husbandry, shearing is the cutting off of the fleece of sheep and  other wool-bearing animals, using special shears.</p><p>shearwater Any of numerous species (family Procellariidae) of long�  winged seabirds named for their habit of gliding on stiff wings along wave  troughs. Typical shearwaters are the 12-17 drab, slender-billed species of  Puffinus, 14-26 in. (35-65 cm) long. Shearwaters nest in a burrow on off�  shore islands and coastal hills in the Atlantic and Mediterranean and  throughout most of the Pacific. A colony may consist of hundreds of  thousands of pairs; at night, when the calling adults move in and out of  the burrows, the din is deafening. See also fulmar, petrel.</p><p>sheathed bacteria Group of bacteria found widely in nature in slow-  running water. Many species are attached to underwater surfaces. They  are characterized by a threadlike, branching arrangement of cells enclosed  in a sheath. The sheaths of some are variously encrusted with iron or  manganese oxides, depending on the water. One of the best-known is a  common species, Sphaerotilus natans\ in polluted water it has thin,  colourless sheaths, and in unpolluted water containing iron it has yellow-  brown, iron-encrusted sheaths that often grow into long slimy tassels.</p><p>Sheba, Queen of (fl. 10th century bc) In Jewish and Islamic tradi�  tions, ruler of the Kingdom of Saba 5 (Sheba) in southwestern Arabia. In  an Old Testament story, she visited King Solomon to test his wisdom. In  Islamic tradition she is known as Bilqls and is converted from worship  of the sun to worship of God, marrying either Solomon himself or a Ham-  danl tribesman. In Persian folklore she is considered the daughter of a  Chinese king and a peri (a type of supernatural being). Ethiopian tradi�  tion names her Makeda; her son by Solomon is seen as the founder of the  Ethiopian royal dynasty.</p><p>Shebele River See Shabeelle River</p><p>Shebeli \sho-ba'-le\ River Somali Shabeelle \sha-'be-le\ River  River, eastern Africa. It rises in the Ethiopian Highlands and flows south�  east through the arid Ogaden Plateau. After crossing into Somalia, it  approaches the coast near Mogadishu, then turns southwest to flow par�  allel with the coast. Its total length is about 1,130 mi (1,820 km). During  rainy periods in Ethiopia, it joins the Jubba River, and the combined waters  then flow to the Indian Ocean. In drier years it disappears in a series of  marshes and sand flats northeast of the Jubba confluence.</p><p>Sheeler, Charles (b. July 16, 1883, Philadelphia, Pa., U.S.�d. May  7, 1965, Dobbs Ferry, N.Y.) U.S. painter and photographer. Educated at  the Pennsylvania Academy of the Fine Arts, he initially earned a living  as a photographer. His acclaimed series of photographs of the Ford auto�  mobile plant at River Rouge, Mich. (1927), was followed by a series on  Chartres Cathedral (1929). In his paintings, early Cubist influences led to  the Precisionism of his maturity. He treated industrial and architectural  subjects in an abstract-realist style, emphasizing their formal qualities, as  in his painting Rolling Power (1939), which revealed the abstract power  of a locomotive�s driving wheels.</p><p>Sheen, Fulton J(ohn) (b. May 8, 1895, El Paso, II. U.S.�d. Dec. 9,  1979, New York, N.Y.) U.S. religious leader. He attended parochial school  and St. Viator College before being ordained to the priesthood in 1919.  He pursued further studies in the U.S. and Belgium. He taught at Catho�  lic University (Washington, D.C.) from 1926 to 1950. In 1930 he began  his 22-year radio career on the program The Catholic Hour, with which  he reached an estimated 4 million listeners. In 1951 he became a titular  bishop, and he served as bishop of Rochester, N.Y. from 1966 to 1969.  In the 1950s he began a weekly television series, Life Is Worth Living ; it  was followed by two more series. He was also the author of numerous  books. At his death he was one of the best-known clerics in the U.S.</p><p>sheep Ruminants (bovid genus Ovis) that have scent glands in the face  and hind feet.

The coat of wild species  consists of outer hair underlain by wool. Sheep graze in flocks, prefer�  ably on short, fine grasses and legumes. They have been domesticated  from at least 5000 bc in the Middle East, Europe, and Central Asia. Most  domesticated breeds produce fine wool; the few that produce only hair or  coarse or long wool are generally raised for meat. The flesh of mature  sheep is called mutton; that of immature sheep is called lamb.</p><p>sheep laurel or lambkill Open upright woody shrub ( Kalmia angus-  tifolia ) of the heath family. Growing 1-4 ft (0.3�1.2 m) high, it has glossy,  leathery, evergreen leaves and showy pink to rose flowers. Like other  Kalmia species (including mountain laurel) and other members of the heath  family, it contains a poison (andromedotoxin). In northwestern North  America, where these plants occur, livestock (especially sheep) that graze  on nonfertile soils of abandoned pastures and meadows may ingest  enough of the plant to become poisoned, potentially fatally.</p><p>sheepdog In general, any dog breed developed to herd sheep; specifi�  cally, the border collie. Most sheepdog breeds stand about 2 ft (60 cm) and  weigh over 50 lbs (23 kg). The French briard has bushy brows and a long,  waterproof coat. The Belgian sheepdog has long black hair and erect ears.  The Hungarian puli has a coat of long ropelike cords. It stands 16-19 in.  (41-48 cm) and weighs about 30 lbs (14 kg).

Sheet erosion commonly occurs on recently  plowed fields or on other sites having poorly consolidated soil material  with scant vegetative cover.</p><p>Sheffield City and metropolitan borough (pop., 2001: 513,234), South  Yorkshire, England. It is situated at the foot of the Pennines. An Anglo-  Saxon village that became the site of a castle and parish church early in  the 12th century, it has been known for its cutlery since medieval times.  By 1700 it had a monopoly of the English cutlery trade, and it remains  the centre of the industry today. It developed a steel industry from the  mid-19th century, and several metallurgical innovations, including the  process for making stainless steel, originated there. In 1568 Mary, Queen  of Scots, was imprisoned in its Norman castle (now in ruins).</p><p>Sheffield plate Articles made of copper coated with silver by fusion.  The technique was discovered c.</p><p>1742 by the Sheffield (Yorkshire,</p><p>Eng.) cutler Thomas Boulsover, who  noted that the combination of fused  silver and copper retained the ductil�  ity of both metals and acted as one  when manipulated. Other workshops  in Britain, continental Europe, and  North America also produced cook�  ing and eating utensils of Sheffield  plate. After the introduction of elec�  troplating in 1840, production of  Sheffield plate declined; by the  1870s it had all but disappeared.</p><p>Admired for its soft, glowing gray  lustre, Sheffield-plate ware soon  came to be prized and collected.</p><p>Sheherazade See Scheherazade</p><p>sheikh Vshek, 'shak\ or shaykh Among Arabic-speaking tribes, espe�  cially Bedouin, the male head of the family, as well as of each succes�  sively larger social unit making up the tribal structure.

It origi�  nated in the 15th century as a container for metal or stone shot, dispersed  when the container burst after leaving the gun. Explosive shells, in use  by the 16th century, were hollow cast-iron balls filled with gunpowder and  lit by a fuse. Until the 18th century, such shells were used only in high-  angle fire (including mortars). In the 19th century, shells were adopted for  direct-fire artillery, notably in the form of shrapnel. Modern artillery shells  consist of a casing (usually steel), a propelling charge, and a bursting  charge; the propelling charge is ignited by a primer at the base of the shell  and the bursting charge by a fuse in the nose. In rifle, pistol, and machine-  gun ammunition, the word usually signifies the brass casing that contains  the propulsive charge. In shotgun ammunition, the shell is the entire car�  tridge, including shot, powder, primer, and case.</p><p>Shell See Royal Dutch Shell plc</p><p>shell structure In building construction, a thin, curved plate structure  shaped to transmit applied forces by compressive, tensile, and shear  stresses that act in the plane of the surface.

He gradually channeled his  passionate pursuit of personal love  and social justice into poetry. His first  major poem, Queen Mab (1813), is a  utopian political epic revealing his  progressive social ideals. In 1814 he  eloped to France with Mary Woll-  stonecraft Godwin (see Mary Shel�  ley); in 1816, after Harriet drowned  herself, they were married. In 1818  the Shelleys moved to Italy. Away  from British politics, he became less  intent on social reform and more  devoted to expressing his ideals in  poetry. He composed the verse tragedy The Cenci (1819) and his master�  piece, the lyric drama Prometheus Unbound (1820), which was published  with some of his finest shorter poems, including �Ode to the West Wind�  and �To a Skylark.� Epipsychidion (1821) is a Dantean fable about the rela�  tionship of sexual desire to spiritual love and artistic creation.

At his best, Sheraton had a  natural approach to contemporary design: he used wood for its own sake,  rather than covering it with such disguises as gilt or modulating it exces�  sively with ormolu mounts.</p><p>Sheridan, Philip H(enry) (b. March 6, 1831, Albany, N.Y., U.S.�d.  Aug. 5, 1888, Nonquitt, Mass.) U.S. army officer. He graduated from West  Point and served at frontier posts. In the American Civil War he led a  Union division in Tennessee and helped win the Battle of Chattanooga  with his cavalry charge up Missionary Ridge. In the East he became com�  mander of the cavalry (1864) and led raids on Confederate forces around  Richmond, Va. As commander of the Army of the Shenandoah, he drove  Confederate forces under Jubal Early from the Shenandoah Valley.

British playwright, orator, and  politician. His family moved to England, and he was educated at Harrow  School in London. He rejected a legal career for the theatre. His comedy  The Rivals (1775) introduced the popular character Mrs. Malaprop and  established him as a leading dramatist. He became manager and later  owner of the Drury Lane Theatre (1776-1809), where his plays were pro�  duced. He won wide acclaim for his comedy of manners The School for  Scandal (1777) and showed his flair for satirical wit again in The Critic  (1779). His plays formed a link in the history of the comedy of manners  between the Restoration drama and the later plays of Oscar Wilde. In 1780  Sheridan became a member of Parliament, where he was a noted orator  for the minority Whig party.</p><p>sheriff In the U.S., the chief law-enforcement officer for the courts in a  county. He is ordinarily elected, and he may appoint a deputy. The sher�  iff and his deputy have the power of police officers to enforce criminal  law and may summon private citizens (the posse comitatus, or �force of  the county�) to help maintain the peace. The main judicial duty of the  sheriff is to execute processes and writs of the courts. Officers of this name  also exist in England, Wales, Scotland, and Northern Ireland. In England  the office of sheriff existed before the Norman Conquest (1066).</p><p>Sherman, Cindy (b. Jan. 19, 1954, Glen Ridge, N.J., U.S.) U.S. pho�  tographer. After graduating from the State University of New York at  Buffalo, Sherman began work on Untitled Film Stills (1977-80), one of  her best-known projects. The series of 8 x 10-inch black-and-white pho�  tographs features Sherman in a variety of roles reminiscent of film noir.  Throughout her career she would continue to be the model in her pho�  tographs, donning wigs and costumes that evoke images from the realms  of advertising, television, film, and fashion and that, in turn, challenge the  cultural stereotypes about women supported by these media. During the  1980s Sherman�s work featured mutilated bodies and reflected concerns  such as eating disorders, insanity, and death. She returned to ironic com�  mentary upon female identities in the 1990s, introducing mannequins and  dolls to some of her photographs.</p><p>Sherman, John (b. May 10, 1823, Lancaster, Ohio, U.S.�d. Oct. 22,  1900, Washington, D.C.) U.S. poli�  tician. A brother of William T. Sher�  man, he served in the U.S. House of  Representatives (1855-61). A fiscal  expert, he helped establish the  national banking system (1863) and  supported legislation that returned  the U.S. to the gold standard. He  served as U.S. secretary of the trea�  sury (1877-81). In the U.S. Senate  (1861-77, 1881-97), he proposed  the Sherman Antitrust Act and the  Sherman Silver Purchase Act (1890).</p><p>He later served briefly as secretary of  state (1897-98), resigning the day  Congress declared war against  Spain.</p><p>Sherman, Roger (b.

Active in trade and law in Connecticut, he  served as judge of the superior court (1766-85) and mayor of New Haven  (1784-93). A delegate to the Continental Congress, he signed the Decla�  ration of Independence and helped draft the Articles of Confederation. At  the Constitutional Convention, he proposed a compromise on congres�  sional representation that combined facets of the two opposing plans by  the large and small states. The result, called the Connecticut (or Great)  Compromise, which was incorporated into the Constitution, provided for  a bicameral legislature with representation based on population in one  house (House of Representatives) and on the principle of equality in the  other (Senate).</p><p>Sherman, William Tecumseh (b. Feb. 8, 1820, Lancaster, Ohio,  U.S.�d. Feb. 14, 1891, New York, N.Y.) U.S. army general. A brother  of John Sherman, he graduated from West Point, served in Florida and</p><p>California, then resigned his commission in 1853 to pursue a banking  career. He rejoined the Union army when the American Civil War broke  out. He fought in the Battle of Bull Run, then served under Ulysses S.  Grant at Shiloh and was promoted to major general. With Grant he helped  win the Vicksburg Campaign and the Battle of Chattanooga. As commander  of the division of the Mississippi, he assembled 100,000 troops for the  invasion of Georgia (1864). After engagements with Confederate troops  under Joseph Johnston, he captured and burned Atlanta and began his  devastating March to the Sea to capture Savannah, leaving a trail of near�  total destruction. In 1865 he marched north, destroying Confederate rail�  roads and sources of supply in North and South Carolina. He accepted the  surrender of Johnston�s army on April 26. Promoted to general, he suc�  ceeded Grant as commander of the army (1869-84). Often credited with  the saying �War is hell,� he was a major architect of modern total war.</p><p>Sherman Antitrust Act (1890) First U.S. legislation enacted to curb  concentrations of power that restrict trade and reduce economic compe�  tition. Proposed by Sen. John Sherman, it made illegal all attempts to  monopolize any part of trade or commerce in the U.S. Initially used  against trade unions, it was more widely enforced under Pres. Theodore  Roosevelt. In 1914 Congress strengthened the act with the Clayton Anti�  trust Act and the formation of the Federal Trade Commission. In 1920 the  U.S. Supreme Court relaxed antitrust regulations so that only �unreason�  able� restraint of trade through acquisitions, mergers, and predatory pric�  ing constituted a violation. Later cases reinforced the prohibition against  monopoly control, including the 1984 break-up of AT&amp;T.

By  studying animals whose cerebral cortexes had been removed, he showed  that reflexes are integrated activities of the total organism, not based on  isolated �reflex arcs.� Sherrington�s law states that when one set of  muscles is stimulated, muscles opposing their action are inhibited. He  showed that the role of proprioception in reflexes that maintain upright  posture against gravity is independent of cerebral function and skin sen�  sation. His work influenced the development of brain surgery and treat�  ment of nervous disorders, and he coined the terms neuron and synapse.  His classic work is The Integrative Action of the Nervous System (1906).  In 1932 he shared a Nobel Prize with Edgar Adrian (1889-1977).</p><p>sherry Fortified wine of Spanish origin. It takes its name from the prov�  ince of Jerez de la Frontera in Spain. Essential to its taste is the action of  flor, a mildewlike growth encouraged by a slight exposure to air after fer�  mentation. Also unique is the solera system of blending wines of many  vintage years. Sherry is fortified after fermentation with high-proof brandy  to 16-18% alcohol. It is served primarily as an aperitif, though sweeter,  heavier sherries are used as dessert wines.</p><p>Sherwood, Robert E(mmet) (b. April 4, 1896, New Rochelle, N.Y.,  U.S.�d. Nov. 14, 1955, New York, N.Y.) U.S. playwright. Sherwood was  a magazine editor in New York City and a member of the Algonquin  Round Table, the centre of a New York literary coterie. He examined the  pointlessness of war in his first play. The Road to Rome (1927). Idiot�s  Delight (1936), Abe Lincoln in Illinois (1938), and There Shall Be No  Night (1940) won Pulitzer prizes. In 1938 he cofounded the Playwrights�  Company, which became a major producing company. During World War  II he wrote speeches for Pres. Franklin D. Roosevelt and headed the over�  seas branch of the Office of War Information (1941-44). His book  Roosevelt and Hopkins (1948) won a Pulitzer Prize. Many of his plays  were adapted for film; his original screenplays include The Best Years of  Our Lives (1946, Academy Award).</p><p>Sherwood Forest Woodland, Nottinghamshire, England.

They form the Shetland administrative region;  the region�s capital is Lerwick. Fewer than 20 of the islands are inhabited.  The northernmost part of Britain, the islands have fjordlike coasts and a  climate warmed by the North Atlantic Current. The Norse ruled the Shet-  lands from the 8th to the 15th century. In 1472 the islands, with Orkney,  were annexed to the Scottish crown. They are famous for their livestock,  which includes the Shetland pony and the Shetland sheep. The latter�s fine  wool is used in the distinctive Shetland and Fair Isle knitted patterns. The  North Sea oil industry has contributed to the economy.</p><p>Shetland pony Breed of pony that originated in Scotland�s Shetland  Islands. Well adapted to the islands� harsh climate and scant food supply,  Shetlands were used as pack horses. Around 1850 they were taken to  England to work in coal mines and to the U.S., where a more refined pony  suitable for children was developed. Except for certain dwarf ponies, the  Shetland is the smallest breed of horse. Its average height is about 40 in.  (102 cm; Shetlands are not measured in hands). Shetlands are long-lived  and need little care; they are gentle and even-tempered if properly trained.</p><p>Shetland sheepdog or sheltie Breed of sheepdog developed from  a Scottish working dog to herd the  small sheep of the Shetland Islands.</p><p>The sheltie resembles the rough-  coated colue but in miniature; it  stands 13-16 in.

He rose in  the Komsomol hierarchy to become first secretary of its central commit�  tee in Georgia (1957-61). He later served as a member of the Soviet  Union�s Central Committee (1976) and a full member of the Politburo  (1985). As foreign minister under Mikhail Gorbachev, he implemented the  Soviet withdrawal from Afghanistan in 1988, new arms treaties with the  U.S., and the Soviet Union�s tacit acquiescence in the fall of the commu�  nist regimes of eastern Europe (1989-90), while promoting the reform  policies of glasnost and perestroika. After the Soviet Union�s collapse, he  returned to the newly independent republic of Georgia, where he was  elected chairman of the State Council (an office then equivalent to presi�  dent) in 1992 and later that year chairman of parliament. He fought orga�  nized crime and tried to find solutions for separatist violence in the  Georgian provinces of South Ossetia and Abkhazia. After surviving an  assassination attempt in August 1995, he was elected president of Geor�  gia in November. His government faced numerous problems, including a  failing economy and charges of corruption and cronyism. In addition,  several elections were marred by allegations of irregularities and fraud.  Faced with growing unrest, Shevardnadze resigned in November 2003.</p><p>Shi'a See ShTite  shiatsu See acupressure</p><p>Shibusawa Eiichi X.shs-bii-'sa-wa-'a-i-cheV (b.

The son of wealthy peasants, he received  samurai status from the shogun Tokugawa Yoshinobu (1837-1913). Fol�  lowing the Meiji Restoration in 1868, he worked in the finance ministry  of the new government. In 1873 he left to become the first president of  Dai-ichi Bank (now Dai-ichi Kangyo Bank). In 1880 he organized the  Osaka Spinning Mill, a major industrial success. He also created a cotton-  spinners� zaibatsu, or cartel, to help the industry and make mutually advan�  tageous arrangements with shippers and merchandisers, a practice  common in industrializing Japan.

Zhao  Zheng (b. c. 259 bc, Qin state, northwestern China�d. 210 bc, Hebei  province) Founder of the Qin dynasty (221-207 bc). His father was king  of Qin, which was regarded as barbarous by the central states of China  but had developed a strong bureaucratic government under the philoso�  phy of legalism (see Hanfeizi). Aided by Li Si, Zheng eliminated the other  Chinese states until in 221 bc Qin ruled supreme. He proclaimed himself  Shihuangdi (�First Sovereign Emperor�) and initiated reforms designed  to create a fully centralized administration. He was interested in magic  and alchemy, hoping for an elixir of immortality; his reliance on magi�  cians was strongly condemned by Confucian scholars, many of whom he  executed. The scholars also advocated a return to old feudal ways; their  obstinacy led him to order the burning of all nonutilitarian books. Tradi�  tional histories regarded him as the ultimate villain, cruel, uncultivated,  and superstitious. Modern historians stress the endurance of his bureau�  cratic and administrative structure. Though the Qin dynasty collapsed  after his death, future dynasties adopted his structures. He was buried in  a massive tomb with an army of more than 6,000 terra-cotta soldiers and  horses.

Mem�  bers of the political faction that supported �Ad, Muhammad�s son-in-law,  as the Prophet�s heir after the murder of the third caliph, 'Uthman, the  Shl'ites gradually became a religious movement after the murder of 'All.  'All�s followers insisted that a caliph, or imam, be a lineal descendant of  'All and his wife, Fajimah. Shl'ite legal tradition is distinct from the four  major schools of thought in Sunnite Islam and is generally regarded as  the most conservative. Though Shl'ites represent only about 10% of Mus�  lims in the world, they are a majority in Iran and Iraq, and there are siz�  able populations in Yemen, Syria, Lebanon, East Africa, Pakistan, and  northern India. The largest subdivision is the Ithna �Ashariyyah, or Twelv�  ers, who recognized 12 historical imams (including 'All); other subsects  include the Isma'Iliyyah and the Zaydiyyah.</p><p>Shijiazhuang Vshi-'jya-'jwaqV or Shih-chia-chuang City (pop.,  1999 est.: 1,338,796), capital of Hebei province, northeastern China.  Located on the edge of the North China Plain at the foot of the Taihang  Mountains, the site dates to pre-Han times (c. 206 bc). After it came under  the Tang dynasty (7th-10th century ad), it was only a local market town.  Its growth into one of China�s major cities began in 1905, when the rail�  way reached the area, stimulating trade and agriculture. Other rail con�  nections and an extensive road network established it as a  communications centre. It developed into an industrial city with admin�  istrative functions at the end of World War II.

A large  contingent of peasants, supported by ronin (masterless samurai), rebelled  in protest of heavy taxation. After initial success, the uprising was  crushed, and an estimated 37,000 rebels were killed. Because many of the  peasants were converts to Christianity, their rebellion strengthened gov�  ernment determination to isolate Japan from foreign influence and vigor�  ously enforce its proscription of all Christian beliefs and activities.</p><p>Shim la formerly Simla City (pop., 2001 prelim.: 142,161), capital of  Himachal Pradesh state, northwestern India. The city was built by the British  after the Gurkha War (1814-16), on a ridge of the Himalayan foothills  some 7,100 ft (2,200 m) high.

The hybridization began on Buddhism�s appearance  in Japan (mid-6th century ad), and the practice of building Shinto and  Buddhist shrines near each other developed in the 8th century. To sepa�  rate the two religions, the government issued an edict in 1868 ordering  Buddhist priests connected with Shinto shrines either to be reordained as  Shinto priests or to return to lay life. Because the state religion was Shinto,  the government abolished Buddhist ceremonies in the imperial household.  Nevertheless, most Japanese incorporate elements of both religions in  their lives, celebrating life-related events (birth, coming of age, marriage)  at Shinto shrines but holding Buddhist funeral rites and memorial services.</p><p>shinden-zukuri \ , shen-,den-zu- , ku-re\ Japanese architectural style of  mansion-estates constructed in the Heian period (794-1185). The form con�  sisted of a shinden (central building) to which subsidiary structures were  connected by corridors. The shinden faced south on an open court, across  which was a pond garden. The eastern and western tainoya, or subsidiary  living quarters, were attached by watadono (corridors), from which narrow  corridors extended south, ending in small pavilions. This layout resulted in  a U-shaped arrangement around the court. See also shoin-zukuri.</p><p>shiner Any of several small freshwater fishes (genera Notemigonus and  Notropis, family Cyprinidae). The common shiner ( Notropis cornutus ) is  a blue and silver minnow up to 8 in. (20 cm) long. The golden shiner  {Notemigonus cryseleucas ), sometimes called the American roach, is a  greenish and golden minnow, about 12 in. (30 cm) long and weighing 1.5  lbs (0.7 kg). It is edible and valuable as bait.</p><p>shingle Thin piece of building material made of wood, asphaltic mate�  rial, slate, metal, or concrete, laid in overlapping rows to shed water.  Shingles are widely used as roof covering on residential buildings and  sometimes also for siding (see Shingle style). Wood shingles in the U.S. are  usually made of cypress, redwood, or Western red cedar.</p><p>Shingle style In the U.S., a style of wood-shingle-covered domestic  architecture of the 1870s and �80s. Among the finest examples are Henry  Hobson Richardson�s Sherman House (1874-75), Newport, R.I., and  Stoughton House (1882-83), Cambridge, Mass. The style grew out of the  Queen Anne and Stick styles and was stimulated by a revived interest in</p><p>colonial American architecture. The small size of the shingle made it easy  to cover a variety of shapes. Like the Stick style, the Shingle style is char�  acterized by a free-flowing, open plan; open porches and irregular roof  lines contribute to the picturesque or rustic effect. The style had a sig�  nificant influence on Frank Lloyd Wright.</p><p>shingles or herpes zoster Vhsr-.pez-'zas-torV Acute viral skin and  nerve infection. Groups of small blisters appear along certain nerve seg�  ments, most often on the back, sometimes after a dull ache at the site;  pain becomes more severe when the blisters break out. Caused by the  same virus as chickenpox, it probably results from reactivation of seem�  ingly inactive virus in a partially immune person. Spontaneous recovery  from the infection usually occurs within two weeks, but neuralgia may  last months or even years longer.</p><p>Shingon \'sheq- l goq,\ English Vshin-,gan\ Esoteric Japanese sect based  on an interpretation of 9th-century Chinese Buddhism. It holds that the  Buddha�s secret wisdom can be developed through special ritual means  (see Yoga) employing body, speech, and mind, including the use of sym�  bolic gestures, mystical syllables, and mental concentration. The whole  is intended to arouse a realization of the spiritual presence of the Buddha  inherent in all living things. Shingon�s main scripture, the Mahavairo-  cana Sutra (�Great Sun Sutra�), is not canonical in other Buddhist  schools. Shingon is properly considered a form of Vajrayana, though it  was much modified and systematized by KOkai.</p><p>Shining Path Spanish Sendero Luminoso Maoist movement in  Peru dedicated to violent revolution. It was founded in 1970 by a phi�  losophy professor, Abimael Guzman Reynoso (b. 1934), as a result of a  split in the Peruvian Communist Party. The senderistas began their cam�  paign among the impoverished Indians of the high Andes, attracting sym�  pathizers by their emphasis on the empowerment of Indians at the expense  of Peru�s traditional elite. They gained control of large areas of Peru  through violence and intimidation. By 1992, when Guzman was captured  and their influence began to wane, they had caused an estimated 25,000  deaths and seriously disrupted the Peruvian economy. Their new leader,  Oscar Ramirez Durand, was sentenced to life imprisonment in 1999.</p><p>Shinran \'shen-,ran\ orig. Matsuwaka-Maru (b. 1173, near Kyoto,  Japan�d. Jan. 9, 1263, Kyoto) Japanese philosopher and religious  reformer. He entered the priesthood at age nine and studied for 20 years  at the centre founded by Saicho on Mount Hiei. He later met Honen,  founder of the Jodo sect (see Pure Land Buddhism). When Honen�s move�  ment was suppressed, he and Shinran were exiled. For more than 20 years,  Shinran lived an academic and missionary life, compiling the six volumes  of his teachings. In 1224 he established Jodo Shinshu (�True Pure Land  sect�). He refined the Pure Land teaching that salvation could be attained  through chanting the name of the Buddha Amida (Amitabha) by saying  that even one such utterance, if made with true faith, was sufficient for  salvation. He advocated marriage for his priests to minimize the distance  between clergy and laity. Jodo Shinshu is the largest Buddhist denomi�  nation in modern Japan.</p><p>Shinto Indigenous religion of Japan. Based on the worship of spirits  known as kami, Shinto has no founder and no official scripture, though its  mythology is collected in the Kojiki (�Records of Ancient Matters�) and  Nihon shoki (�Chronicles of Japan�), written in the 8th century. The term  Shinto (�Way of the Kami�) came into use to distinguish indigenous Japa�  nese beliefs from Buddhism, which had been introduced into Japan in the  6th century. At Shinto�s core are beliefs in the kami 1 s mysterious creat�  ing and harmonizing power. According to Shinto myths, in the beginning  a certain number of kami simply emerged, and a pair of kami, Izanagi and  Izanami, gave birth to the Japanese islands, as well as to the kami who  became ancestors of the various clans. The Japanese imperial family  claims descent from Izanagi�s daughter, the sun goddess Amaterasu. All  kami are said to cooperate with one another, and life lived in accordance  with their will is believed to produce a mystical power that gains their  protection, cooperation, and approval. Through veneration and observa�  tion of prescribed rituals at shrines (e.g., ritual purity), practitioners of  Shinto can come to understand and live in accordance with divine will.  In the early 21st century, Shinto had nearly 2.8 million followers. See  also shinbutsu shOgo.</p><p>shinty Dr shinny Game similar to hurling and field hockey.

First levied in medieval times, the tax required  payment in the form of a number of warships or their equivalent in money.  It was revived in 1634 by Charles I to raise extra revenue. He issued six  annual writs (1634-39) that extended the imposition to inland towns and  sought to establish it as a permanent tax. Its enforcement aroused wide�  spread opposition and added to the discontent leading to the English Civil  Wars. In 1641 the tax was declared illegal by Parliament.</p><p>ship of the line Type of sailing warship, the principal vessel of the  West�s great navies from the mid-17th to the mid-19th century. It evolved  from a tactic in naval warfare known as the line of battle, in which two  opposing columns of ships maneuvered to fire their guns broadside against  each other. Since the largest ships carrying the biggest guns usually won  these battles, this led to the construction of more big line-of-battle ships,  or ships of the line. These three-masted ships were often 200 ft (60 m)  long, displaced 1,200-2,000 tons (1,100-1,800 metric tons), and had  crews of 600-800 men; they usually had 60-110 cannons and other guns  arranged along three decks. They eventually gave way to the steam-  powered BATTLESHIP.</p><p>Shipka Pass Pass in the Balkan Mountains, central Bulgaria. The pass  is 4,376 ft (1,334 m) high.

Oct. 21, 1736, Philadelphia, Pa.�d. July  11, 1808, Philadelphia, Pa., U.S.) U.S. physician. He earned his M.D. in  Edinburgh. In 1762 he established the first American maternity hospital,  and in 1765, with John Morgan, he organized the first medical school in  the American colonies, where he became the first systematic teacher of  anatomy, surgery, and obstetrics. He was one of the first to use dissected  human bodies to teach anatomy. He succeeded Morgan as head medical  officer of the Continental Army in 1777. He was a founder and president  of the College of Physicians of Philadelphia, the first American medical  school.</p><p>shipping Transporting of goods and passengers by water. Early civili�  zations, which arose by waterways, depended on watercraft for transport.  The Egyptians were probably the first to use seagoing vessels (c. 1500  bc); the Phoenicians, Cretans, Greeks, and Romans also all relied on  waterways. In Asia, Chinese ships equipped with multiple masts and a  rudder were making sea voyages by c. ad 200; from as early as the 4th  century bc the Chinese also relied heavily on internal waterways to trans�  port food to their large cities (see Grand Canal). Japan, too mountainous  to rely on roads for mass transport, also relied on internal and coastal  waterways for shipping from early in its history. The spice trade was a  great stimulus to shipping trade; Arabians were sailing to the spice islands  before the Christian era and European merchant marines grew up largely  because of it. The tea trade had a similar effect, as did the discovery of  gold in the New World. From the 17th to the 19th century, the slave trade  was a major feature of Atlantic shipping. The U.S. and England were the  ascendant shipping nations in the 19th century; Germany, Norway, Japan,  The Netherlands, and France joined them in the early 20th century, with  Greece dominating the industry by the century�s end. Transoceanic ship�  ping remains a vital part of the world economy. Many U.S. merchant ships  are registered in a third nation to avoid heavy taxes.

He earned a Ph.D. from the Tokyo Institute of Technology in 1966.  After graduation he began teaching at the University of Tsukuba. In 1977  he started collaborating with Alan J. Heeger and Alan G. MacDiarmid,  conducting experiments on the polymer polyacetylene. Their work dem�  onstrated that certain plastics can be chemically changed to conduct elec�  tricity almost as readily as metals. Other conductive polymers were later  discovered, and the finding was expected to play a significant role in the  emerging field of molecular electronics. With Heeger and MacDiarmid,  Shirakawa was awarded the Nobel Prize for Chemistry in 2000.</p><p>Shiraz \she-'raz\ Industrial and commercial city (pop., 1996: 1,053,025),  south-central Iran. It was important during the Seleucid (312-175 bc),  Parthian (247 bc-ad 224), and Sasanian (c. ad 224-651) periods but  reached its economic and cultural peak in the 10th� 11th centuries, dur�  ing the Islamic period. In the 14th century, Timur occupied Shiraz, which  had by that time become a Muslim centre rivaling Baghdad. In 1724 it  was sacked by Afghan invaders and later became the capital of the Per�  sian Zand dynasty (1750-94). Famous for its wine, gardens, shrines, and  mosques, it was the birthplace of the Persian poets Sa c d! and Hafez, who  remain local icons and whose tombs are located there.</p><p>Shire River Vshir-a\ River, southern Malawi and central Mozambique.

Berlin Diary (1941) col�  lects his impressions of European political events. He was blacklisted in  the McCarthy era as a leftist sympathizer. He is best known for The Rise  and Fall of the Third Reich (1969, National Book Award), a massive study  of Nazi Germany.

The Qu�ran stresses that God does not share his powers with  any partner ( sharik ) and warns that those who believe in idols will be  harshly dealt with on the Day of Judgment. The concept of shirk has  broadened considerably throughout the dogmatic development of Islam,  and it has come to be used as the opposite of taw hid (the oneness of God).  Different grades of shirk have been distinguished by Islamic law; they  include the belief in superstition, belief in the power of created things  (e.g., reverencing saints), and belief in those who profess to know the  future�all of which pale beside polytheism in seriousness.</p><p>Shirley, William (b.

Feb. 19, 1630, or April 1627, Shivner,  Pune, India�d. April 3, 1680, Rajgarh) Indian king (r. 1674-80), founder  of the Maratha kingdom of India. A devout Hindu, he grew up at a time  when India was ruled by Muslims, and he found their religious persecu�  tion intolerable. Collecting a band of followers, he began in c. 1655 to  seize weak outposts of the sultan of Bijapur. In 1659 he lured the sultan�s  army to its destruction and, possessed of its horses and armaments,  became overnight a formidable warlord. The Mughal emperor Aurangzeb  sent out his most prominent general and an army of 100,000 to capture  him, but Shivaji made a daring escape. Gaining even more strength, he  added a naval force to his military might. In 1674 he proclaimed himself  an independent sovereign. He forged an alliance with the sultans in the  south, thereby blocking the spread of Mughal rule. His rule was noted for  its religious tolerance.

From 1914 he was a major voice in the critical movement called Russian  Formalism, to which he contributed the concept of ostranenie, or �making it  strange.� He argued that literature is a collection of devices that force read�  ers to view the world afresh by presenting old ideas or mundane experi�  ences in new, unusual ways. His earlier works include the acclaimed  memoir A Sentimental Journey (1923) and The Technique of the Writer�s  Craft (1928). Official Soviet displeasure with Formalism later obliged him  to write within the constraints of Socialist Realism, and he published histori�  cal novels, film criticism, and highly praised literary studies.</p><p>shock State in which the circulatory system fails to supply enough blood  to peripheral tissues to meet basic requirements. Symptoms�weak, rapid  pulse; low blood pressure; and cold, sweaty skin�are not all present in  every case. Causes include low blood volume, caused by bleeding or fluid  loss from burns or dehydration; inability of the heart to pump enough  blood, due to heart attack, pulmonary embolism, or cardiac tamponade  (compression of the heart by fluid in the membrane around it); and blood�  vessel dilation as a result of septicemia, allergy (including anaphylaxis), or  drugs. All result in reduced capillary blood flow; reflexes increase heart  rate and constrict small blood vessels to protect the blood supply to essen�  tial organs. Without treatment of the underlying cause, these mechanisms  fail; since the cause is not always clear, cases tend to require different and  occasionally contradictory treatment (e.g., intravenous fluids can save the  life of a patient with massive blood loss but can overload a weakened  heart).</p><p>shock absorber Device for controlling unwanted motion of a spring-  mounted vehicle. On an automobile, the springs act as a cushion between  the axles and the body and reduce the shocks produced by a rough road  surface.

Early examples from Mesopotamia were moccasinlike wrap�</p><p>arounds of leather; not until the Hellenistic Age did shoes become luxu�  rious. The Romans developed shoes fitted for the left and right feet, and  differentiated according to sex and rank. In the 14th�15th century, shoes  became extremely long and pointed, the points attaining a length of 18  in. (45 cm) or more. In the 16th century, the toes became extremely broad,  like a duck�s bill. In the 17th century, shoes had moderately high heels  and were often decorated with large rosettes of lace and ribbons, which  gave way to gold or silver buckles in the 18th century. The first shoe fac�  tory opened in 1760, in Massachusetts, but not until the development of  modern machinery in the 19th century were shoes made quickly and  inexpensively.</p><p>Shoemaker, Bill or Willie Shoemaker in full William Lee  Shoemaker (b.

As the shden increased in numbers, they undermined  the political and economic power of the central government and contrib�  uted to the growth of powerful local clans. Landowners would commend  their parcels of land to powerful families or religious institutions with  tax-free status, thereby obtaining that status for themselves. All people  connected with the land�the powerful patron, the owner, and the estate  manager�had rights to part of the income from the land. During the  Kamakura period (1192-1333), the shogunate (military government)  asserted authority over the shden by inserting its own stewards ( MO ) into  each estate to collect taxes. During Japan�s Warring States period, the  shden gave way to consolidated landholdings controlled by daimyo  (domain lords). See also samurai.</p><p>shogi Vsho-ge\ Strategic board game for two players that evolved in  Japan from the 8th to the 12th century. Although often called Japanese  chess in the West, shogi is played with a board (9 x 9), pieces (flat,  wedge-shaped tiles, all of one colour, with rank given by text on each  side), and rules that are completely unlike those of chess. Its most unique  feature is known as the drop, whereby a captured piece can be placed on  an empty square, subject to certain restrictions. Most pieces are promoted  to another piece, indicated by flipping its tile, after reaching particular  regions of the board. Ownership of each piece is indicated by the direc�  tion of the wedge.</p><p>shogun Vsh6-gon\ Japanese "barbarian-quelling generalis�  simo" In Japanese history, a military ruler. The title was first used dur�  ing the Heian period, when it was occasionally bestowed on a general after  a successful campaign. In 1185 Minamoto Yoritomo gained military con�  trol of Japan; seven years later he assumed the title of shogun and formed  the first bakufu, or shogunate (see Kamakura period). Later Kamakura sho�  guns lost real power to the Hojo family while remaining rulers in name.  Ashikaga Takauji received the title of shogun in 1338 and established the  Ashikaga shogunate (see Muromachi period), but his successors enjoyed  even less control over Japan than had the Kamakura shoguns, and the  country gradually fell into civil war (see Onin War). Tokugawa Ieyasu�s  shogunate (see Tokugawa period) proved the most durable, but the Japa�  nese penchant for titular rulers prevailed, and in time a council of elders  from the main branches of the Tokugawa clan ruled from behind the  scenes. Since the title of shogun ultimately came from the emperor, he  became a rallying point for those who brought down the shogunate in the  Meiji Restoration.</p><p>shoin-zukuri \'sh6-en-zu-'ku-re\ Style of Japanese domestic architec�  ture. The name is taken from a feature called the shoin, a study alcove  with a built-in desk. Other common features included the tokonoma and  chigai-dana (built-in shelves).

A native of the Don River region, he served in the Red  Army and joined the Communist Party in 1932. He is best known for the  huge novel The Quiet Don, translated in two parts as And Quiet Flows  the Don (1934) and The Don Flows Home to the Sea (1940). A portrayal  of the struggle between the Cossacks and Bolsheviks, it was heralded in  the Soviet Union as a powerful example of Socialist Realism and became  the most widely read novel in Russia. It became controversial when Alek�  sandr Solzhenitsyn and others alleged that it was plagiarized from the Cos�  sack writer Fyodor Kryukov (d. 1920). Sholokhov�s later novels include  Virgin Soil Upturned (1932-60).

The river was named  for the Shoshone Indians.</p><p>Shostakovich \,shas-t3-'ko-vich\, Dmitry (Dmitriyevich) (b. Sept.  25, 1906, St. Petersburg, Russia�d. Aug. 9, 1975, Moscow, Russia,  U.S.S.R.) Russian composer. Shaped by his intellectual parents and the  political turmoil of his youth, he was admitted to the St. Petersburg Con�  servatory at age 13. His Symphony No. 1 (1924-25) attracted international  attention for its convincing command of a large scale and its expressive  palette ranging from unaffected lyricism to bitter satire to grand heroics. He  experimented with avant-garde trends in his next symphonies and theatre  works, such as the opera Lady Macbeth ofMtsensk (1932; revised as Kat�  erina Izmaylova). The denunciation of Lady Macbeth by the Soviet  authorities in 1936 led to his adopting a very different style that was serious  and elegiac, with a directness that appealed to the public. His wartime Sym�  phony No. 7 (1941), thought to portray the German invasion, became a  symbol of patriotism. After his music was denounced by the government in  1948, he was again devastated and began putting his most personal feelings  into chamber works, particularly the remarkable 15 string quartets. With  the Cold War �thaw� of the late 1950s, he composed two outspokenly per�  sonal late symphonies, including the 13th (1962). He is remembered as the  greatest Russian composer to follow Igor Stravinsky.</p><p>shot put Field event in which a metal ball is heaved for distance. It  derives from the ancient event of �putting the stone�; later a shot (can�  nonball) was substituted. A 16-lb (7.3-kg) shot was adopted for men in  the first modem Olympic Games (1896); an 8.8-lb (4-kg) weight is used  by women.</p><p>shotcrete or gunite Concrete applied by spraying. Shotcrete is a mix�  ture of Portland cement, aggregate, and water conveyed by compressed air  to a spray gun. For structural uses, shotcrete is usually sprayed over a  framework of reinforcing bars and steel mesh. Because it can take any  shape, is easily coloured, and can be sculpted after application, it is used  for a variety of specialized structures, including artificial rock walls, zoo  enclosures, canopies, shell structures, pools, and dams. It is sometimes  used to bind the walls of tunnels.</p><p>shotgun Smoothbore shoulder firearm designed to fire a number of pel�  lets, or shot, that cover a large target area after they leave the muzzle. It  is used mainly against small game such as birds. The earliest examples  were the fowling pieces that appeared in 16th-century Europe. Repeating  shotguns, in which several cartridges could be loaded at once, became  available in the 1880s. The range of a modern shotgun is about 50 yards  (45 m).</p><p>Shotoku in full Shotoku Taishi \sho-'to-ku-'ta-e-she\ English  Crown Prince Shotoku (b. 574, Yamato, Japan�d. April 8, 622,  Yamato) Important Japanese regent and scholar of the Asuka period who  promoted Buddhism and Confucianism, reinstituted embassies to China,  and adopted the Chinese calendar and court ranks. He built the HoryO  Temple and is sometimes credited with writing the Seventeen-Article Con�  stitution, which describes Confucian ethical concepts and the Chinese  bureaucratic system. Since his death he has been regarded as a Buddhist  saint.</p><p>shoveler Any of four species (genus Anas, family Anatidae) of dabbling  ducks having a long, spoon-shaped bill. The migratory northern shoveler  (A. clypeata) inhabits shallow marshes and lagoons in the Americas,  Europe, Africa, and Asia. The male has a green head, white breast, chest�  nut belly and sides, and a blue patch on the fore wing. It uses its bill to  sift small organisms and seeds from the mud; in deeper waters, it skims  the surface for plankton. The other species are the South American red  shoveler (A. platalea)\ the Cape, or Smith�s, shoveler (A. smithii ) of South  Africa; and the Australasian, or blue-winged, shoveler (A. rhynchotis).</p><p>show jumping Competitive riding of horses through an obstacle  course.

The first decades  of the period were marked by the rise of militarism in the 1930s and by  Japan�s disastrous participation in World War II, resulting in the coun�  try�s complete collapse and ultimate surrender. The postwar era was one  of rehabilitation, during which it joined the UN (1956), hosted the 1964  Summer Olympics, and held the Osaka World Exposition in 1970. Japan  experienced a so-called �economic miracle,� with annual growth averag�  ing 10% in 1955-60 and higher in the years following. In the 1980s the  Japanese economy became one of the world�s largest and most sophisti�  cated, with per capita income surpassing that of the U.S. Japanese soci�  ety became increasingly urban, with one-tenth of the population living in  Tokyo by mid-decade. U.S. influence on popular culture was strong, and  young Japanese emulated their U.S. counterparts in numerous ways. Other  societal changes during the Showa period included more people living in  nuclear families than in extended families, love marriages rather than  arranged marriages, fewer children per family, and more opportunities for  women. See also Heisei period; Occupation (of Japan).</p><p>shrapnel \'shrap-n 3 l\ Originally, a type of projectile invented by the Brit�  ish artillery officer Henry Shrapnel (1761-1842), containing small spheri�  cal bullets and an explosive charge to scatter the shot and fragments of the  shell casing. A time fuse set off the explosive charge late in the shell�s flight,  when it was near opposing troops. The resulting hail of high-velocity debris  was often lethal; it caused most of the artillery-inflicted wounds in World  War I. In World War II a high-explosive bursting charge that fragmented the  shell�s iron casing made shrapnel balls unnecessary; the term shrapnel  came to be used for the shell-casing fragments.</p><p>Shreve, Henry Miller (b. Oct. 21, 1785, Burlington county, N.J.,  U.S.�d. March 6, 1851, St. Louis, Mo.) U.S. inventor and explorer. He  grew up on the western Pennsylvania frontier and began making trading  voyages after his father�s death in 1799. In the War of 1812 he was skip�  per of the Enterprise, the second steamboat on the Mississippi, carrying  supplies for Andrew Jackson�s army. Though it was the first steamboat to  reach Louisville, Ky. (1815), the trip convinced Shreve of the need for a  new design for river steamers. His design for the Washington �with a flat  shallow hull, a steam engine on the main deck, and a second deck�  established the Mississippi steamboat type. To clear rivers of debris, he  later designed the first snag boat. His camp on the Red River in Louisi�  ana grew into a permanent settlement as Shreveport.</p><p>Shreveport City (pop., 2000: 200,145), northwestern Louisiana, U.S.  It is located on the banks of the Red River. In 1837 Shreveport was  founded on land bought from the Caddo Indians. The city became a Con�  federate state capital and army headquarters during the American Civil  War. It developed rapidly after oil was discovered in 1906 and is now a  commercial and industrial centre for a three-state region. Barksdale Air  Force Base is near the city.</p><p>shrew Any of more than 300 species of small insectivores constituting  the family Soricidae. About 40% of these species live in Africa, but shrews  are also found throughout the Northern Hemisphere. Shrews are absent  from Australia and most of South America. They have tiny eyes and ears,  a movable snout, and long, hook-tipped incisors. Typically 2 to 3 in. (6  to 8 cm) long, with a shorter tail, many shrews weigh only about 0.5 oz  (14 g). Some are considered the smallest mammals, weighing only a few  grams, with bodies less than 2 in. long. Most species live in ground lit�  ter, but some live in burrows or trees and a few are semiaquatic. Because  they are so small, shrews have the highest metabolic rates of any mam�  mals (with pulses as high as 800 beats per minute). They spend most of  their time searching for food, as they can survive only a few hours with�  out eating. Their normal prey is invertebrates such as worms, though some  will eat other small animals as well. Some species have toxic saliva (pain�  ful to humans). Raptors and snakes eat shrews, but mammals avoid them.  Tree shrews (family Tupaiidae) belong to a separate mammalian order  (Scandentia) unrelated to true shrews.</p><p>Shrewsbury Town (pop., 1995 est.: 63,000), borough of Shrewsbury  and Atcham, administrative and historic county of Shropshire, England.

Founded in the 5th century</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Shrewsbury &#x25BA; shuffleboard I 1745</p><p>ad by the Welsh kingdom of Powys, it became part of the Anglo-Saxon  kingdom of Mercia at the end of the 8th century. An 11th-century grant  to Roger de Montgomery, who founded its abbey, made it one of the first  English earldoms. Prosperity came to the area in the late Middle Ages  after centuries of fighting with the Welsh ended and trading in Welsh wool  and flax began. The town was the birthplace of Charles Darwin.</p><p>Shrewsbury, Charles Talbot, duke and 12th earl of (b. July  24, 1660�d. Feb. 1, 1718, London, Eng.) English statesman. He inher�  ited his father�s title at age seven and was raised as a Catholic. He became  a Protestant in 1679 and in 1688 was one of seven men who invited Wil�  liam of Orange to seize power from James II. After aiding the successful  rebellion, Shrewsbury served William III as secretary of state (1689-90,  1694-99) and was created a duke in 1694. Shifting his allegiance from  the Whigs, he served in a Tory administration as lord lieutenant of Ire�  land (1710-14) and was appointed by Queen Anne as lord high treasurer  (1714). He obtained recognition of George I as the legitimate royal heir  and assured the peaceful succession of the house of Hanover.</p><p>Shridhara (fl. c. 750, India) Highly esteemed Hindu mathematician  who wrote several treatises on Indian mathematics. His extant works are  the partially preserved Pcitiganita (�Mathematics of Procedures�), Gan-  itasara (�Essence of Mathematics�), and Ganitapanchavimashi (�Math�  ematics in 25 Verses�). Pcitiganita consists of versified mathematical  rules, without proofs. The first part treats arithmetic operations (includ�  ing the calculation of squares, square roots, cubes, and cubic roots) for  both integers and fractions, reductions of fractions, and proportions. The  second part presents mixture problems and various series before it breaks  off in the midst of rules for plane figures. He composed Ganitasara and  Ganitapanchavimashi as epitomes of a larger work, which may or may  not have been Patiganita. He gave the first correct formulas in India for  the volume of a sphere and of a truncated cone.</p><p>shrike Any of about 64 species of solitary, predatory songbirds (family  Laniidae), especially any of the 25 species of the genus Lanius. Shrikes  kill insects, lizards, mice, and birds with their bill or may impale their  prey on a thorn (earning them the name butcher bird). Most species are  gray or brownish and have a harsh call; several Eurasian species have  reddish or brown markings. The great gray shrike (L. excubitor ), called  northern shrike in Canada and the U.S., is about 10 in. (25 cm) long and  has a black mask. The only other New World species is the similar but  smaller loggerhead shrike (L. ludovicianus) of North America.</p><p>shrimp Any of approximately 2,000 decapod species (suborder Natan-  tia) having a semitransparent body  flattened from side to side and a flex�  ible abdomen terminating in a fan�  like tail. The appendages are  modified for swimming, and the  antennae are long and whiplike.</p><p>Shrimps occur in shallow and deep  ocean waters and in lakes and  streams. Species range from less  than an inch (a few millimeters) to  about 8 in. (20 cm) long. Larger spe�  cies are often called prawns. Shrimps  swim backward by rapidly flexing  the abdomen and tail. They eat small plants and animals; some species  eat carrion. Many species are commercially important as food.

He wrote Ganitatilaka (�The Ornament of Mathemat�  ics�) and the astronomical works Siddhantashekhara (�The Crest of  Established Doctrines�), Dhikotidakarana (�Procedure Giving Intellec�  tual Climax�), and Dhruvamanasa (�Permanent Mind�). Siddhantashek�  hara includes two chapters on mathematics; as one of the few surviving  documents from this period, it sheds important light on the state of Indian  algebra between Brahmagupta and Bhaskara II. For horoscopic astrology,  Shripati wrote Jatakakarmapaddhati (�Way to the Computation of Nativ�  ity�) and Jyotisharatnamala (�A Jewel Necklace of Astral Science�),  which were highly influential on the development of astrology in India.</p><p>Shropshire Vshrap-shir\ Administrative (pop., 2001: 283,240), geo�  graphic, and historic county, western England. It is divided by the River  Severn; its county seat is Shrewsbury. Remnants left by Neolithic, Bronze  Age, and early Iron Age inhabitants have been found in the region. In the</p><p>1st century ad the Romans built a fortress at Viroconium, one of the larg�  est towns in Roman Britain. The Saxon conquest brought the construc�  tion of Offa's Dyke, marking the England-Wales border. After the Norman  Conquest of 1066, a double line of castles was established as fortifica�  tion against the Welsh. In the 13th century the high quality of Shropshire  wool brought prosperity to the region. In the early 18th century it became  the greatest iron-producing area in England. Iron founding and agricul�  ture remain important. The administrative county of Shropshire comprises  five districts: Bridgnorth, North Shropshire, South Shropshire, and the  boroughs of Oswestry and Shrewsbury and Atcham.</p><p>Shroud of Turin See Shroud of Turin</p><p>shrub Any woody plant that has several stems, none of which is domi�  nant, and is usually less than 10 ft (3 m) tall. When much-branched and  dense, it may be called a bush. Intermediate between shrubs and trees are  arborescences, or treelike shrubs (10-20 ft, or 3-6 m, tall). Trees are gen�  erally defined as woody plants more than 20 ft (6 m) tall, having a domi�  nant stem, or trunk, and a definite crown shape. These distinctions are not  reliable, however; for example, under especially favourable environmen�  tal conditions, some shrubs may grow to the size of an arborescence or  even a small tree.</p><p>Shu \'shii\ In Egyptian religion, the god of the air and supporter of the sky,  created by the god Atum. Shu and his sister Tefnut (goddess of moisture)  were the first couple of the group of nine gods called the Ennead of  Heliopolis. Of their union were born Geb and Nut. Shu was portrayed in  human form with an ostrich feather on his head. He was often represented  supporting with uplifted arms the body of Nut arched above him. Later  he was frequently termed the son of Re, and he was also identified with  Onuris, a warrior god.</p><p>Shu (907 -65) Ancient name for Sichuan and the name of two of the 10  kingdoms included in China�s Ten Kingdoms period (907-c. 980), spe�  cifically the Qian (Former) Shu (907-25) and the Hou (Later) Shu (934-  65).

After emi�  grating from Russia with their parents in 1882, the two oldest brothers,  Lee (1872-1953) and Sam (c. 1875-1905), leased theatres and presented  plays in Syracuse, N.Y., in the 1890s. By 1900 Jacob (1880-1963) had  joined the business, and the brothers leased their first theatres in New York  City. Coming into conflict with the Theatrical Syndicate, which controlled  U.S. theatrical bookings, they led an independent movement to fight the  syndicate and prevailed after a long legal battle. After Sam�s death, Lee  and Jacob built theatres across the U.S. and came to own more than 60  legitimate houses and many vaudeville and movie theatres. They produced  more than 1,000 different shows, including 600 plays, revues, and musi�  cals. Theatrical unions such as Actors� Equity were formed in response  to their often sharp business practices. Charged with monopoly practices  in 1950, they sold a number of theatres in 1956 but retained prestigious  houses in many cities.</p><p>Shubra al-Khaymah \shu-'bra-el-'ka-m9\ City (pop., 1996:  870,716), Egypt.

It extends from  the Ural Mountains to the Pacific Ocean and from the Arctic Ocean to  central Kazakhstan and the boundaries of China and Mongolia; it covers  more than 5,000,000 sq mi (13,000,000 sq km). It is notorious for the  length and severity of its almost snowless winters. Temperatures of -90  �F (-68 �C) have been recorded. The first settlers probably arrived in  southern Siberia in the Paleolithic Period. The area was under Chinese  influence from c. 1000 bc, followed by the Turkic-Mongols in the 3rd  century bc. Russian trappers and Cossack explorers (see Cossacks) colo�  nized it in the late 16th century, and by the mid-18th century most of  Siberia was under Russian rule. It was connected to other parts of Russia  by the Trans-Siberian Railroad. Eastern Siberia was the scene of the anti-  Bolshevik government of Aleksandr Kolchak (1918-20). It was made part  of the Russian S.F.S.R. in 1922. Russia exiled criminals and political  prisoners there, and in the 1930s Joseph Stalin set up forced-labour camps  that fueled industrial growth. When Russian factories were relocated there  during World War II, it played an important role in the war effort. It has  deposits of coal, petroleum, natural gas, diamonds, iron ore, and gold; its  chief industrial products include steel, aluminum, and machinery. South�  ern Siberia produces wheat, rye, oats, and sunflowers. Its main cities  include Novosibirsk, Omsk, Krasnoyarsk, and Irkutsk.</p><p>Siberian husky Breed of dog developed in Siberia by the Chukchi  people, who used it as a sled dog, companion, and guard. It was brought  to Alaska in 1909 for sled-dog races and became established as a consis�  tent winner. A graceful dog with erect ears and a dense, soft coat, it stands  20-24 in. (51-60 cm) and weighs 35-60 lbs (16-27 kg). It is usually gray,  tan, or black and white; head markings may resemble a cap, mask, or  spectacles. The breed, kept pure for hundreds of years in Siberia, is noted  for intelligence and a gentle temperament.</p><p>Siberian peoples Any of a large number of small ethnic groups living  in Siberia. Most engage either in reindeer herding or fishing, while some  also hunt furbearing animals or farm and raise horses or cattle. In the past,  many had both summer and winter dwellings, their winter homes some�  times being partially or entirely underground and their summer homes  being various styles of tent. Shamanism was common, and the family was  the basic societal unit. The Soviet government attempted to settle Siberian  peoples on collective farms and to introduce new occupations, but some  groups, such as the Koryak and the Nenets, still engage in their traditional  pursuits. Other Siberian peoples include the Chukchi, Evenk, Ket, Khanty,  Mansi, Sakha, and Yukaghir. See also Paleo-Siberian languages.</p><p>Siberut V.se-bo-'ruA Island, Indonesia.

The coast is low and swampy;  the inland is savanna. Agriculture is the chief occupation.</p><p>Sibyl Prophetess of Greek legend. She was a figure of the mythical past  whose prophecies, phrased in Greek hexameters, were handed down in  writing. In the late 4th century bc, the number of Sibyls multiplied, and  the term sibyl was treated as a title. Sibyls were associated with various  oracles, especially those of Apollo, who was said to be their inspiration.  They were typically depicted as extremely old women who lived in caves  and delivered their prophecies in an ecstatic frenzy. A famous collection  of prophecies, the Sibylline Books , was traditionally kept in the temple of  Jupiter, to be consulted only in emergencies.</p><p>Sichuan Vse-'chwan, 'se-'chwan\ or Ssu-ch'uan conventional  Szechwan Province (pop., 2002 est.: 86,730,000), upper Yangtze River  (Chang Jiang) valley, southwestern China. It is bordered by Qinghai,  Gansu, Shaanxi, Guizhou, and Yunnan provinces, Chongqing municipal�  ity, and Tibet. It has an area of 188,000 sq mi (487,000 sq km) and encom�  passes the central depression called the Sichuan (or Red) Basin; its capital  is Chengdu. Sichuan is one of China�s most densely populated and eth�  nically diverse provinces. It was among the first areas to be settled by the  Chinese (5th century bc). From the Zhou dynasty (1046-256 bc) until the  Song dynasty (ad 960-1279), it was administered through various politi�  cal subdivisions. It was established as a province during the Qing dynasty  (1644-1911/12). During the Sino-Japanese War (1937^15), it served as  the seat (at Chongqing) of the Nationalist government; the Japanese never  penetrated the area. It is China�s leading producer of rice, corn (maize),  sweet potatoes, cattle, and pigs. The most industrialized province of south�</p><p>western China, it is a centre for coal mining, petroleum refining, and  chemical production. Sichuan�s spicy cuisine is renowned worldwide.</p><p>Sicilian school Group of Sicilian, southern Italian, and Tuscan poets  centred in the courts of Frederick II (r. 1194-1250) and his son Manfred of  Sicily (d. 1266). They established the vernacular, as opposed to Provencal,  as the standard language for Italian love poetry and are also credited with  inventing two major Italian poetic forms, the canzone and the sonnet.  Some 125 of their poems are extant, many by Giacomo Da Lentini (fl.  13th century), the school�s senior poet. The Sicilian-school sonnet  became, with variations, the dominant poetic form in Renaissance Italy  and Elizabethan England, where it was modified to form the English, or  Shakespearean, sonnet.</p><p>Sicilian Vespers (1282) Massacre of the French that began a Sicilian  revolt against the Angevin king Charles I. Backed by Peter III of Aragon,  the rising broke out when Sicilians killed some insulting French soldiers  at vespers in the church of Santo Spirito in Palermo. The people of the  city followed suit and massacred 2,000 of its French inhabitants. All of  Sicily soon revolted and sought help from the Aragonese, and the war  became a French-Aragonese struggle for possession of Sicily. The con�  flict was finally resolved when the Sicilians chose Frederick III, brother  of the king of Aragon, as their ruler in 1302.</p><p>Sicily Vsi-s9-le\ Italian Sicilia \si-'sil-y3\ Island, Italy. Sicily is sepa�  rated from the mainland by the Strait of Messina. The largest island (9,830  sq mi [25,460 sq km]) in the Mediterranean Sea, it is also the site of  Europe�s highest active volcano, Mount Etna. The capital is Palermo.  Sicily�s strategic location at the centre of the Mediterranean has made the  island a crossroads of history. The Greeks colonized it in the 8th-6th cen�  turies bc, and in the 3rd century bc it became the first Roman province. It  came under Byzantine rule in the 6th century ad and fell in 965 to Arabs  from North Africa. It was taken in 1060 by the Normans. In the 12th-13th  centuries and again in the 18th century it formed part of the Kingdom of  the Two Sicilies. During the 19th century it was a major centre of revolu�  tionary movements; in 1860 it was liberated from the Bourbons, and in  1861 it was incorporated into the Kingdom of Italy. Agriculture is its eco�  nomic mainstay; industries include oil refining, food processing, wine  making, and shipbuilding. Together with the islands of Egadi, Lipari,  Pelagie, and Panteleria, Sicily forms an autonomous region of Italy (pop.,  2001 prelim.: 4,866,202).</p><p>sickle-cell anemia Blood disorder (see hemoglobinopathy) seen mainly  in persons of Sub-Saharan African ancestry and their descendants and in  those from the Middle East, the Mediterranean area, and India. About 1  in 400 blacks worldwide has the disease, caused by inheriting two copies  of a recessive gene that makes those with one copy (about 1 in 12 blacks  worldwide) resistant to malaria. The gene specifies a variant hemoglobin  (hemoglobin S or Hb S) that distorts red blood cells (erythrocytes) into a  rigid sickle shape. The cells become clogged in capillaries, damaging or  destroying various tissues. Symptoms include chronic anemia, shortness  of breath, fever, and episodic �crises� (severe pain in the abdomen, bones,  or muscles). Hydroxyurea treatment triggers production of fetal hemo�  globin (Hb F), which does not sickle,  greatly lessening severity of crises  and increasing life expectancy, pre�  viously about 45 years.</p><p>Sicyon \'si-se-9n\ Ancient city,  northern Peloponnese, southern  Greece.

His Methods of Ethics (1874) is considered by some the most sig�  nificant 19th-century ethical work in English. Drawing on the utilitarianism  of John Stuart Mill and the categorical imperative of Immanuel Kant, he pro�  posed a system of �universalistic hedonism� that would reconcile the  apparent conflict between the pleasure of self and the pleasure of others.  His other writings include Principles of Political Economy (1883) and Ele�  ments of Politics (1891). He also cofounded the Society for Psychical  Research (1882) and helped found Cambridge�s first women�s college.</p><p>SIdT Muhammad ibn Yusuf See Muhammad V</p><p>STdT Muhammad Idris al-Mahdl al-SanusT See Idris I</p><p>siding Material used to surface the exterior of a building to protect  against exposure to the elements, prevent heat loss, and visually unify the  facade. The word siding implies wood units, or products imitative of  wood, used on houses. There are many different types of siding, includ�  ing clapboard, horizontal lap siding, vertical board siding, and shingles.  Board and batten siding, sometimes found in Carpenter Gothic houses and  very modest structures, differs from the common clapboard in that it con�  sists of vertical wood boards with their butt joints covered by battens  (narrow strips), imparting a seamed appearance. Both aluminum and  polyvinyl-fluoride-coated siding (commonly called vinyl siding) were  developed as maintenance-free alternatives to wood clapboard; they  mimic its horizontal boards. Fiberboard, a pressed-wood-pulp product, is  sometimes used, though its long-term durability is limited. In larger build�  ings, the exterior covering is called cladding, and may be of brick, glass  in a metal framework, or stone, concrete, or metal panels.</p><p>Sidney, Sir Philip (b.

Born  into an aristocratic family and educated to be a statesman and soldier, Sid�  ney served in minor official posts and turned to literature as an outlet for his  energies. Astrophel and Stella (1591), inspired by Sidney�s passion for his  aunt�s married ward, is considered the finest Elizabethan sonnet cycle after  William Shakespeare�s sonnets. The Defence ofPoesie (1595), an urbane and  eloquent plea for imaginative literature, introduced the critical ideas of</p><p>Renaissance theorists to England. His heroic romance Arcadia, though  unfinished, is the most important work of English prose fiction of the 16th  century. None of his works was published in his lifetime. Wounded in  action while soldiering in the Netherlands, he died from an infection, and  he was widely mourned as the ideal gentleman of his day.</p><p>Sidon Vsid- 3 n\ Arabic Sayda Seaport (pop., latest est.: 140,000), south�  western Lebanon.

Ruled successively in ancient times by the  Assyrians, Babylonians, and Persians, it was conquered by Alexander the  Great (c. 330 bc). Under Roman rule by the 1st century bc, it was an  important centre for the manufacture of glass and purple dyes. It changed  hands several times during the Crusades and fell to the Muslims in 1291.

In 1861 he patented the open-hearth furnace (see open-hearth  process), which was soon being widely used in steelmaking and eventu�  ally replaced the earlier Bessemer process. He also made a reputation and  a fortune in the steel cable and telegraph industries and was a principal in  the company that laid the first successful transatlantic telegraph cable  (1866).

The first Siemens company, Siemens &amp; Halske, was founded in Berlin in  1847 to build telegraph installations. Under Werner Siemens (1816-92)  and his three brothers (including William Siemens), it expanded to pro�  duce dynamos, cables, telephones, electric power, and electric lighting. In  1903 Siemens &amp; Halske transferred its power-engineering activities to the  new Siemens-Schuckertwerke GmbH, and in 1932 Siemens-Reiniger-  Werke AG was established to produce medical equipment. The compa�  nies expanded greatly during the Third Reich; after World War II, Siemens  officials were charged with using slave labour and participating in the  construction and operation of the Auschwitz and Buchenwald camps. The  Siemens companies flourished again in the 1950s, and by 1966, when the  three separate companies merged to form Siemens AG, were among the  world�s largest electrical suppliers.

Rivalry with Florence made Siena the  center of pro-imperial Ghibellinism in Tuscany. It was conquered by  Charles I (Charles of Anjou), king of Naples and Sicily, in 1270 and joined  the Guelph confederation (see Guelphs and Ghibellines). It was an impor�  tant banking and commercial centre until surpassed by Florence in the  13th�14th centuries. Conquered by the Holy Roman emperor Charles V  in 1555, it was ceded to Florence in 1557.

Lan�  guages: English (official), Krio (derived  from English and a variety of African lan�  guages). Religions: Islam (predominantly  Sunni), traditional beliefs, Christianity. Cur�  rency: leone. Sierra Leone has four physical regions: the coastal sw&amp;  the Sierra Leone Peninsula, with thickly wooded mountains that rise from</p><p>the swamps; the interior plains, consisting of grasslands and rolling  wooded country; and the eastern plateau region, encompassing several  mountains. About one-eighth of the country is forest. Wildlife includes  chimpanzees, tigers, crocodiles, and many species of birds. The economy  is based largely on agriculture and mining; rice, cassava, coffee, cacao,  and oil palm are major crops, and diamonds and bauxite are mined. Sierra  Leone is a republic with one legislative house; the head of state and gov�  ernment is the president. The earliest inhabitants were probably the Bulom  and Temne; Mande-speaking peoples began arriving in the 15th century.  The coastal region was visited by the Portuguese in the 15th century, who  built a fort near the site of modern Freetown. European ships visited the  coast regularly to trade for slaves and ivory, and the English built trading  posts on offshore islands in the 17th century. British abolitionists and phi�  lanthropists founded Freetown in 1787 as a private venture for freed and  runaway slaves. In 1808 the coastal settlement became a British colony.  The region became a British protectorate in 1896. It achieved indepen�  dence in 1961 and became a republic in 1971. Since independence Sierra  Leone has experienced a series of military coups.

He left his paternal uncle  Charles (later Charles IX) as regent in  Sweden and returned to Poland, but  Charles later rose in rebellion,  defeated Sigismund�s army (1598),  and deposed Sigismund (1599).</p><p>Poland and Sweden fought intermit�  tently from 1600 as Sigismund tried  to regain the Swedish throne. He  invaded Russia in the Time of  Troubles and held Moscow (1610�</p><p>12). In a renewal of the Polish-  Swedish conflict in 1621, King  Gustav II Adolf seized most of Polish  Livonia, which Sweden retained  under the terms of a 1629 truce.</p><p>sign In marketing and advertising,  a device placed on or before a premises to identify its occupant and the  nature of the business done there or, placed at a distance, to advertise a  business or its products. The ancient Egyptians and Greeks used signs for  advertising purposes, as did the Romans, who also, in effect, created sign�  boards by whitewashing convenient sections of walls for suitable inscrip�  tions. Early shop signs were developed when tradesmen, dealing with a  largely illiterate public, devised certain easily recognizable emblems to  represent their trades. Modem sign designers use various forms of ani�  mation and light.</p><p>Sigismund Ilf detail of a painting,  school of Rubens; in the Bayerische  Staatsgemdldesammlungen, Munich</p><p>COURTESY OF THE BAYERISCHE  STAATSGEMALDESAMMLUNGEN, MUNICH</p><p>sign language Any means of communication through bodily move�  ments, especially of the hands and arms, rather than through speech.

Charles-Michel, abbe de l�Epee (1712-89), developed the  first sign language for the deaf in the mid-18th century; his system devel�  oped into French Sign Language (FSL), still used in France. Transported  to the U.S. in 1816 by Thomas Gallaudet (1787-1851), it evolved into  American Sign Language (ASL, or Ameslan), now used by more than  half a million people.

At 18 he gave up architecture to pursue painting in  the Impressionist manner. In 1884 he became a founder of the Salon des  Independants. With Georges Seurat he developed an exact mathematical  system of applying dots of colour, which they called Pointillism (see  Neo-Impressionism). He traveled extensively along the European coast  painting landscapes and seascapes; in his later years he painted street  scenes of Paris and other cities. He was a master of watercolour, in which  he achieved great brilliance of colour and a free, spontaneous style. His  work had a great influence on Henri Matisse.</p><p>Signorelli \,sen-yo-'rel-le\, Luca (d'Egidio di Ventura de') or  Luca da Cortona (b. 1445/50, Cortona, Republic of Florence�d.

He went to  Rome c. 1483, where he produced the Testament of Moses fresco in the  Sistine Chapel. The dramatic action and depiction of great muscular effort  in this and similar Renaissance works mark him as essentially a Floren�  tine naturalist.

In the first war Sikhs invaded British India under  the pretext of forestalling a British attack on the Sikh state in the Punjab  (see Ranjit Singh). They were defeated, the British annexed some of their  lands, and British troops and a British resident were stationed in Lahore.

The  sikhara over the sanctuary of a  temple is usually tapered convexly,  consisting of piled-up roof slabs of  diminishing size. The surface is cov�  ered with vinelike candrashala  (ogee arch) tracery; at the top is a  cushion-shaped grooved disk  (i amalaka ), and above that a pot with  a crowning finial. The sikhara devel�  oped during the Gupta period (4th-  6th century ad) and steadily grew  taller and more elaborate, as in the  soaring tower of the 11th-century  Lingaraja Temple in Bhubaneswar. In  a variation of the basic form, half  spires are added on either side of the  sikhara ; excellent examples are the  10th-century Laksmana and 11th-  century Kandarya Mahadeva  temples at Khajuraho, Madhya  Pradesh. In addition to the curved  sikhara, there is a smaller, rectilinear  type frequently used above the  temple mandapas (halls).</p><p>Sikhism \ , se- l kiz-om\ Indian reli�  gion founded in the late 15 th century  by Nanak, the first of the Sikh leaders titled Guru. Most of the religion�s  25 million members, called Sikhs, live in the Punjab �the site of their  holiest shrine, the Golden Temple, and the principal seat of Sikh religious  authority, the Akal Takht. The Adi Granth is the canonical scripture of  Sikhism. Its theology is based on a supreme God who governs with jus�  tice and grace. Every human being, irrespective of caste or gender, has  the opportunity to become one with God. The basic human flaw of self�  centredness can be overcome through proper reverence for God, commit�  ment to hard work, service to humanity, and sharing the fruits of one�s  labour. Sikhs consider themselves disciples of the 10 human Gurus; the  Adi Granth assumed the position of Guru after the death of the last human  Guru, Gobind Singh (1666-1708). Sikhs accept the Hindu ideas of sam-  sara and karma. The dominant order of Sikhism, into which most Sikh  boys and girls are initiated at puberty, is the Khalsa. The emblems of the  Khalsa, called the five Ks, are kes (uncut hair), kangha (a comb), kachha  (long shorts), kirpan (a sword), and karka (a steel bracelet).</p><p>Sikkim Ysi-ksnA State (pop., 2001 prelim.: 540,773), northeastern India.

It is also bordered by Bhutan  and West Bengal state and has an area of 2,740 sq mi (7,096 sq km); the  capital, Gangtok, is the only urban centre. As an independent country, it  fought prolonged wars in the 18th and 19th centuries with Bhutan and  Nepal. It first came under British influence in 1817, though it remained  an independent buffer between British India and Tibet. In 1950 it became  an Indian protectorate and, in 1975, a state of India.

He served as prime minister of Poland (1923�24) and as minister of mili�  tary affairs (1924-25). From 1928 he joined the opposition to the gov�  ernment controlled by J6zef Pilsudski. After the German invasion of Poland  (1939), he became prime minister of the Polish government-in-exile.  When he asked Joseph Stalin to allow the Red Cross to investigate the  Katyn Massacre, Stalin broke off Soviet-Polish diplomatic contact.

It now lies mainly in  southwestern Poland, with parts in Germany and the Czech Republic. It  was originally a Polish province that became a possession of the Bohemian  crown, and thus part of the Holy Roman Empire, in 1335. Because of suc�  cession disputes and the region�s prosperity, there were at least 16 Silesian  principalities by the end of the 15th century. It passed to the Austrian Habs-  burgs in 1526; it was taken by Prussia in 1742. After World War I it was  divided between Poland, Czechoslovakia, and Germany. During World  War II Polish Silesia was occupied by Germany and was the site of atroci�  ties against the population by Nazi and, later, Soviet forces. In 1945 the  Allied powers assigned virtually all of Silesia to Poland; today its nine Pol�  ish provinces contain almost one-fourth of Poland�s population.</p><p>Silhak See Practical Learning  School</p><p>silhouette \,si-lu-'et\ Outline  image or design in a single solid, flat  colour, giving the appearance of a  shadow cast by a solid figure. The  term is usually applied to profile por�  traits in black against white (or vice  versa), either painted or cut from  paper, especially popular c. 1750-  1850 as the least expensive method  of portraiture. The name derives  from Etienne de Silhouette, Louis  XV�s finance minister, notorious for  his frugality and his hobby of mak�  ing cut-paper shadow portraits. In  17th-century Europe, shadow por�  traits and scenes were produced by  drawing the outline cast by candle�  light or lamplight; when paper  became widely available, they were  often cut out freehand directly from  life. Photography rendered silhou�  ettes nearly obsolete, and they  became a type of folk art practiced  by itinerant artists and caricaturists.</p><p>silica mineral Vsi-li-koN Any of  the forms of silicon dioxide (Si0 2 ),</p><p>Silhouette portrait by Charles Willson  Peale; in the Library of Congress,  Washington, D.C.</p><p>COURTESY OF THE LIBRARY OF CONGRESS, WASHINGTON,  D.C.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1752 I silicate mineral &#x25BA; Silla</p><p>including quartz, tridymite, cristobalite, coesite, stishovite, melanophlog-  ite, lechatelierite, and chalcedony. Various kinds of silica minerals have  been produced synthetically.</p><p>silicate mineral Any of a large group of silicon-oxygen compounds  that are widely distributed throughout much of the solar system. The sili�  cates make up about 95% of the Earth�s crust and upper mantle, occur�  ring as the major constituents of most igneous rocks and in appreciable  quantities in sedimentary and metamorphic rocks. They also are important  constituents of lunar samples, meteorites, and most asteroids. In addition,  planetary probes have detected them on the surfaces of Mercury, Venus,  and Mars. Of the approximately 600 known silicate minerals, only the  FELDSPARS, AMPHIBOLES, PYROXENES, MICAS, OLIVINES, FELDSPATHOIDS, and ZEOLITES are  significant in rock formation.</p><p>siliceous rock \s9-Ti-shos\ Any of a group of sedimentary rocks that  consist largely or almost entirely of silicon dioxide (Si0 2 ), either as quartz  or as chert, the most common siliceous rock. It occurs in beds and in nod�  ules. Bedded cherts may be an original organic or inorganic precipitate.  Nodular cherts appear to be produced by the alteration of preexisting  sedimentary rock. In this process silica distributed throughout the rock  dissolves and reprecipitates to form nodules.</p><p>silicon Nonmetallic to semimetallic chemical element, chemical symbol  Si, atomic number 14. Second only to oxygen in abundance in Earth�s  crust, it never occurs free but is found in almost all rocks and in sand,  clay, and soils, combined with oxygen as silica (silicon dioxide, Si0 2 ) or  with oxygen and metals as silicate minerals. It occurs in many plants and  some animals. Pure silicon is a hard, dark gray solid with a metallic lus�  tre and the same crystal structure as diamond. It is an extremely impor�  tant semiconductor; doped (see dopant) with boron, phosphorus, or arsenic,  it is used in various electronic circuit and switching devices, including  computer chips, transistors, and diodes. Silicon is also used in metallurgy  as a reducing (see reduction) agent and in steel, brass, and bronze. Its usual  valence in compounds is 4. Silica is used in the form of sand and clay for  many purposes; as quartz, it may be heated to form special GLASSes. Sili�  cates are used in making glass, enamels, and ceramics; sodium silicates  (water glass) are used in soaps, wood treatment, cements, and dyeing.

Roughly  bounded by San Francisco Bay on the north, the Santa Cruz Mountains  on the west, and the Diablo Range on the east, it takes its (unofficial)  name from the extensive use of silicon in the region�s electronics indus�  tries. The U.S. government invested heavily in the region�s industry fol�  lowing World War II. A second economic surge occurred with the  proliferation of personal computers in the 1980s, and a third surge followed  the growth of the Internet in the 1990s.</p><p>silicone or polysiloxane Any of a diverse class of polymers manu�  factured as fluids, resins, or elastomers. They are partially organic com�  pounds, but, unlike most polymers, they have a backbone containing no  carbon, composed instead of alternating silicon and oxygen atoms. In most  silicones, two organic groups (see functional group), usually methyl or  phenyl, are attached to each silicon atom. Silicones in general are excep�  tionally stable and inert. Silicone fluids are used in hydraulic fluids,  emulsion-breaking compositions, and breast implants and as adhesives,  lubricants, water repellents, and protective coatings. Silicone rubbers are  used as electrical insulators in encapsulations, coatings, and varnishes; as  gaskets and caulking material; in specialized tubing; as automobile engine  components; as flexible windows in face masks and air locks; for lami�  nating glass cloth; and as surgical membranes and implants.</p><p>silicosis \,si-b-'ko-s9s\ Common pneumoconiosis caused by long-term  inhalation of silica mineral dust. Known since the 18th century, it usually  occurs after 10-20 years of exposure in jobs such as mining, stonecutting,  grinding, or polishing. The smallest particles do the most damage, kill�  ing macrophages (see reticuloendothelial system) that engulf them in the  pulmonary alveoli. Dead cells accumulate, forming fibrous masses that  reduce lung elasticity. Decreased lung volume and poor gas exchange lead  to shortness of breath and then to coughing, difficulty in breathing, and  weakness. Patients are vulnerable to tuberculosis, emphysema, and pneumo�  nia. In the absence of effective treatment, control of silicosis depends on  prevention with face masks, proper ventilation, and X-ray monitoring of  workers� lungs.</p><p>Siljan Vsil-,yan\, Lake Lake, central Sweden. Covering 112 sq mi (290  sq km), it is Sweden�s third largest lake. It is fed by the Osterdal River  and extends into two bays. Its wooded shores are interspersed with mead�  ows and quaint villages, making it an attractive tourist destination.</p><p>silk Animal fibre produced by certain insects as building material for  cocoons and webs. In commercial use it refers almost entirely to filament  from cocoons produced by the caterpillars of several moth species of the  genus Bombyx, commonly called silkworms. Silk is a continuous filament  around each cocoon. It is freed by softening the cocoon in water and then  locating the filament end; the filaments from several cocoons are unwound  at the same time, sometimes with a slight twist, to form a single strand.  In the process called throwing, several very thin strands are twisted  together to make thicker, stronger yarn. Silk was discovered in China  sometime before 2700 bc, and the secret of its production was closely  guarded for millennia. Along with jade and spices, silk was the primary  commodity traded along the Silk Road beginning about 100 bc. Since  World War II, nylon and other synthetic fibres have replaced silk in many  applications (e.g., parachutes, hosiery, dental floss), but silk remains an  important luxury material for clothing and home furnishings. More than  50% of the world�s silk is still produced in China.</p><p>Silk Road Ancient trade route that linked China with Europe. Origi�  nally a caravan route and used from c. 100 bc, the 4,000-mi (6,400-km)  road started in Xi'an, China, followed the Great Wall to the northwest,  climbed the Pamir Mtns., crossed Afghanistan, and went on to the east�  ern Mediterranean Sea, where goods were taken by boat to Rome. Silk  was carried westward, while wool, gold, and silver were carried eastward.  With the fall of Rome, the route became unsafe; it was revived under the  Mongols, and Marco Polo used it in the 13th century.</p><p>silkscreen or serigraphy \s3-'ri-gr3-fe\ Sophisticated stenciling  technique for surface printing, in which a design is cut out of paper or  another thin, strong material and then printed by rubbing, rolling, or spray�  ing paint or ink through the cutout areas. It was developed c. 1900 and  originally used in advertising and display work. In the 1950s fine artists  began to use the process. It got its name from the fine-mesh silk that,  when tacked to a wooden frame, serves as a support for the cut-paper  stencil, which is glued to it. To make a silkscreen print, the wooden frame  holding the screen is hinged to a slightly larger wooden board, the print�  ing paper is placed on the board under the screen, and the paint is pressed  through the screen with a squeegee (rubber blade) the same width as the  screen. Many colours can be used, with a separate screen for each colour.</p><p>silkworm moth Any moth in the genus Bombyx (family Bombycidae).  The Chinese silkworm ( B. mori ) has  been used in commercial silk produc�  tion for centuries. The adult, which  has a wingspan of about 2 in. (50  mm) and a thick, hairy body, lives  only two or three days. The female  lays 300-500 eggs. The pale, naked  larvae are fed mulberry leaves until  pupation begins, when they are about  3 in. (75 mm) long. They spin a  cocoon of one continuous white or  yellow silken thread, about 1,000  yards (900 m) long. The pupa is  killed with hot air or steam to pre�  serve the thread intact.

Changes in the understanding of the nature  of simony and the relationship between lay and religious orders contributed  to the perception of the growth of simony, even though corrupt practices  did exist.

The</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Singapore &#x25BA; Sino-French War I 1757</p><p>economy is based largely on international trade and finance; there are more  than 100 commercial banks, most of which are foreign, and the headquar�  ters of the Asian Dollar Market is located there. The port is one of the larg�  est in the world, and the country is one of the world�s leading petroleum  refiners. Manufacturing (notably electronic equipment) is also important.  Singapore is a republic with one legislative house; its chief of state is the  president, and the head of government is the prime minister. Long inhab�  ited by fishermen and pirates, it was an outpost of the Sumatran empire of  Shrivijaya until the 14th century, when it passed to Java and then Ayutthaya  (Siam). It became part of the Malacca empire in the 15th century. In the  16th century the Portuguese controlled the area; they were followed by the  Dutch in the 17th century. In 1819 it was ceded to the British East India  Company, becoming part of the Straits Settlements and the centre of British  colonial activity in Southeast Asia. During World War II the Japanese occu�  pied the island (1942-45). In 1946 it became a crown colony. It achieved  full internal self-government in 1959, became part of Malaysia in 1963,  and gained independence in 1965. Singapore is influential in the affairs of  the Association of Southeast Asian Nations (ASEAN). The country�s domi�  nant voice in politics for 30 years after independence was Lee Kuan Yew.  Singapore has become a regional economic powerhouse.</p><p>Singapore City (2002 est.: 4,204,000), capital of the Republic of Sin�  gapore. A free port centred on the southern part of Singapore island, it so  dominates the island that the republic is now commonly considered a  city-state. Known as the Garden City for its many parks and tree-lined  streets, it offers glimpses into the cultures brought to it by immigrants  from all parts of Asia. Traditionally founded by a Shrivijayan prince, it  was an important Malay city in the 13th century. Destroyed by the Jav�  anese in the 14th century, it was refounded by Stamford Raffles of the  British East India Company in 1819. It became the capital of the Straits  Settlements in 1833 and developed as a port and naval base; today it is one  of the world�s great commercial centres. Its thriving banking, insurance,  and brokerage firms make it the chief trading and financial centre of  Southeast Asia. It is home to the National University of Singapore (1980).</p><p>Singer, Isaac Bashevis Yiddish Yitskhok Bashevis Zinger (b.</p><p>July 14?, 1904, Radzymin, Pol., Russian Empire�d. July 24, 1991, Surf-  side, Fla., U.S.) Polish-born U.S. writer of novels, short stories, and  essays. He received a traditional Jewish education at the Warsaw Rab�  binical Seminary. After publishing his first novel, Satan in Goray (1932),  he immigrated to the U.S. in 1935 and wrote for the Jewish Daily For�  ward, a Yiddish newspaper in New York. Though he continued to write  mostly in Yiddish, he personally supervised the English translations.  Depicting Jewish life in Poland and the U.S., his works are a rich blend  of irony, wit, and wisdom, flavoured distinctively with the occult and the  grotesque. His works include the novels The Family Moskat (1950), The  Magician of Lublin (1960), and Enemies: A Love Story (1972; film, 1989);  the story collections Gimpel the Fool (1957), The Spinoza of Market Street  (1961), and A Crown of Feathers (1973, National Book Award); and the  play Yentl the Yeshiva Boy (1974; film, 1983). He was awarded the Nobel  Prize for Literature in 1978.</p><p>Singer, Isaac Merritt (b. Oct. 27,1811, Pittstown, N.Y., U.S.�d. July  23, 1875, Torquay, Devon, Eng.) U.S. inventor and manufacturer. He  became an apprentice machinist at 19. He patented a rock-drilling  machine (1839) and a metal- and wood-carving machine (1849) before  producing an improved version of Elias Howe�s sewing machine in 1851  and soon thereafter founding I.M. Singer &amp; Co. (see Singer Co.) to manu�  facture it. Howe�s successful patent-infringement suit against him in 1854  did not prevent Singer from manufacturing his machine, and his company  was soon the world�s largest sewing-machine producer. He patented  numerous further improvements in the technology; he also pioneered the  use of installment credit plans.</p><p>Singer NV U.S. sewing-machine manufacturer. The company began in  1851, when Isaac Merritt Singer (1811-75) patented the first practical sew�  ing machine for domestic use. By 1860 I.M. Singer &amp; Co. was the larg�  est maker of sewing machines in the world. In 1863 its business was taken  over by the newly incorporated Singer Manufacturing Co. The company  began mass-producing domestic electric machines in 1910 and pioneered  marketing innovations such as the installment plan. It later expanded into  power tools, floor-care products, furniture, and electronics; it adopted the  name Singer Co. in 1963. Its sewing-machine and furniture operations  were spun off into a separate company, SSMC Inc., in 1986. Two years  later it was the subject of a hostile takeover by investor Paul Bilzerian,  who in 1989 sold Singer�s assets to Semi-Tech, a Hong Kong company</p><p>controlled by investor James Henry Ting. Still one of the world�s largest  sewing-machine manufacturers, the company declared bankruptcy in  1999 and was reorganized as Singer NV in 2000.</p><p>Singitic \sin-'ji-tik\ Gulf Inlet of the Aegean Sea, northeastern Greece.

The main community on the gulf is Ouranopolis, a  stop for tourists exploring Mount Athos.</p><p>single tax Tax on land values intended as the sole source of govern�  ment revenues, replacing all existing taxes. Henry George proposed the  single tax in his book Progress and Poverty (1879). The plan gained con�  siderable support in subsequent decades but was never implemented.  Advocates argued that since land is a fixed resource, the income it yields  is a product of the economy�s growth and not individual effort, and that  it therefore can fairly be taxed to support the government. Critics pro�  tested that the single tax would take no account of an individual�s ability  to pay, since there is no correlation between land ownership and total  wealth or income.</p><p>Singspiel Ysiq-.spel, 'ziq-,shpel\ German "song-play" Eighteenth-  century opera in the German language, containing spoken dialogue and  usually comic in tone. The earliest Singspiels were light plays in which  the dialogue was interspersed with popular songs. In Vienna the form had  a brief but intense flowering that resulted in Wolfgang Amadeus Mozart�s  enduring Abduction from the Seraglio (1782) and The Magic Flute (1791).  Singspiel evolved into transitional works such as Ludwig van Beethoven�s  Fidelio (1805) and ultimately gave rise to German Romantic opera.

Sinkholes vary  greatly in area and depth and may be very large. The two main varieties  are those caused by the collapse of a cavern roof, and those caused by  the gradual dissolving of rock under a soil mantle. Collapsed sinkholes  generally have steep rock sides and may receive streams that then flow  underground. Soil-mantled sinkholes are generally shallower; they may  become clogged with clay and hold a small lake.</p><p>Sinkiang See Xinjiang</p><p>sinking fund Fund set aside by a corporation or government agency  for the purpose of periodically redeeming bonds, debentures, and preferred  stocks. The fund is accumulated from earnings, and payments into the  fund may be based on either a fixed percentage of the outstanding debt or  a fixed percentage of profits. Sinking funds are administered separately  from the corporation�s working funds by a trust company or trustee. The  purpose of a sinking fund is to assure investors that provision has been  made for the repayment of bonds at maturity.</p><p>Sinn Fein Vshin-'fanV Irish "We Alone" Nationalist political party in  Ireland. It was founded by Arthur Griffith and others in 1902, and its  policy involved passive resistance to the British, withholding of taxes, and  establishing an Irish ruling council. The party had little impact until after  the Easter Rising, when the demand of its leader Eamon de Valera for a  united, republican Ireland won the party 73 out of 105 seats in the 1918  election. Its power diminished after 1926, when de Valera founded Fianna  Fail, which absorbed most of Sinn Fein�s membership. The party contin�  ued as the political arm of the Irish Republican Army, actively supporting  Irish unification. Under the leadership of Gerry Adams in the late 20th and  early 21st centuries, Sinn Fein participated in the peace talks on North�  ern Ireland and became one of the leading Roman Catholic parties in  Northern Ireland.</p><p>Sino-French War (1883 -85) Conflict between China and France over  Vietnam. It revealed the inadequacy of China�s modernization efforts and  aroused nationalistic sentiment in southern China. In 1880, when France  began to extend its presence in Vietnam northward from the three south-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1758 I Sino-Japanese War &#x25BA; Sippar</p><p>ern provinces it controlled, China sent in troops and engaged in limited  battles. The governor-general, Li Hongzhang, negotiated an agreement  whereby northern Vietnam would be a joint protectorate, but a hard-line  government faction in China rejected it. The French defeated Chinese  reinforcements in 1883, and the new settlement was more strongly in  France�s favour. This, too, was rejected in China; after further hostilities,  the new Chinese fleet of 11 steamers was destroyed, as was a large ship�  yard at Fuzhou. In 1885 China signed a peace treaty accepting the settle�  ment of 1883.</p><p>Sino-Japanese War Either of two conflicts between China and Japan  in the 19th and 20th centuries. The first (1894-95), over Korea, marked  the emergence of Japan as a world power and demonstrated the weakness  of China. Though Korea had long been China�s most important client  state, Japan became interested in it for its natural resources and its stra�  tegic location. After Japan opened Korea to foreign trade in 1875, ten�  sions between radical, pro-Japanese Koreans, who favoured  modernization, and conservative Korean government officials, who were  supported by China, brought China and Japan into conflict. Foreign  observers predicted an easy victory for the more massive Chinese forces,  but Japan scored overwhelming victories on both land and sea. In the  Treaty of Shimonoseki, China recognized the independence of Korea and  ceded Taiwan, the Pescadores, and the Liaodong Peninsula (the last of  which Japan was later forced to return) to Japan. The second conflict  (1937�45) denotes the period of China�s resistance to Japan�s aggression  in Chinese territory after Japan had established itself in Manchuria; it  ended with Japan�s defeat in World War II.

They include Tibetan, Burmese, Karen, and many other languages of  Nepal, India, Myanmar (Burma), Bangladesh, China, and Thailand.  Tibetan and Burmese are the only Tibeto-Burman languages with long  literary traditions. Burmese is written in an adaptation of the Mon script  (see Mon -Khmer ianguages).</p><p>sinter Mineral deposit with a porous or vesicular texture (having small  cavities). Siliceous sinter is a deposit of opaline or amorphous silica that  occurs as an incrustation around hot springs and geysers and sometimes  forms conical mounds (geyser cones) or terraces. Calcareous sinter, some�  times called tufa, calcareous tufa, or calc-tufa, is a deposit of calcium car�  bonate.</p><p>sintering Welding together of small particles of metal by applying heat  at temperatures below the melting point. The process is used to form  complex shapes, to produce alloys, and to allow work on metals with very  high melting points. Sintering is also used in the preliminary molding of  ceramic or glass powders into forms that can then be permanently fixed  by firing. See also powder metallurgy.</p><p>sinus Body cavity or hollow. The paranasal sinuses, which are known  commonly simply as the sinuses, are any of four sets of cavities in the  bones adjoining the nose: maxillary, the largest, between the eye socket  and the palate and upper jaw; frontal, just above and between the eye</p><p>The paranasal sinuses.</p><p>� MERRIAM-WEBSTER INC.</p><p>sockets; ethmoid, consisting of 3-18 thin-walled cavities between the  nasal cavities and the eye sockets; and sphenoid, behind the nasal cavity.  All are absent or small at birth, enlarge gradually until puberty, and then  grow rapidly. They affect the sound of the voice and may help to warm  inhaled air. Their lining produces mucus, which drains into the nasal cav�  ity. Blockage of their outlets by swelling (from allergy or infection; see  sinusitis), polyps, or structural problems hampers breathing through the nose  and can lead to serious infection. Severe obstruction may require surgery,  which must be done with extreme care to avoid harm to nearby brain  structures or the eyes.</p><p>sinusitis \,sl-n3-'si-t9s\ Inflammation of the sinuses. Acute sinusitis, usu�  ally due to infections such as the common cold, causes localized pain and  tenderness, nasal obstruction and discharge, and malaise. Nose drops or  inhalations containing drugs that contract blood vessels help drain the  sinuses. Antibiotics may be used for bacterial infections. Chronic sinusi�  tis, with frequent colds, pus, obstructed breathing, loss of sense of smell,  and sometimes headache, may follow repeated or untreated acute attacks,  particularly with impaired breathing or drainage. If antibiotic therapy or  repeated lavage (rinsing out) does not help, surgery to open passages for  drainage may be needed.</p><p>Siouan Ysii-onV languages Family of North American Indian lan�  guages, spoken mainly west of the Mississippi River in the 17th and 18th  centuries. The principal languages and language groups at this time were  Winnebago in Wisconsin, Chiwere (Iowa, Oto, and Missouri) in Iowa and  northern Missouri, Dhegiha (Ponca, Omaha, Kansa, Osage, Quapaw) in  an area extending from eastern Nebraska to Arkansas, Sioux or Dakota  (a range of dialects including Santee or Dakota proper in Minnesota, Teton  or Lakota in North and South Dakota, and Assiniboine in Canada), Hidatsa  and Mandan on the middle Missouri River, and Crow in Wyoming and  Montana. Separated from the main body of Siouan languages were the  now-extinct languages Tufelo and Biloxi, near the Gulf of Mexico, and  the distantly related Catawba, once spoken in South Carolina. The extant  Siouan languages are now spoken mainly or solely by older adults.</p><p>Sioux Vsii\ or Dakota or Lakota Any of a number of North Ameri�  can Plains Indian peoples living mostly in North Dakota, South Dakota,  Montana, and Nebraska, U.S. They comprise the Santee (Eastern Sioux),  Yankton, and Teton (Western Sioux), each of which in turn has lesser  divisions (e.g., Blackfoot, Oglala). Their languages belong to the Siouan  language stock. The name Sioux is a French derivation of an Ojibwa name  for �enemy� or �snake.� They call themselves Dakota, meaning �Friend.�  In the 17th century the Sioux lived in the area around Lake Superior, but  attacks from the Ojibwa drove them west into Minnesota. They adopted a  Plains way of life, hunting buffalo, living in tepees, emphasizing valour in  warfare, and practicing the sun dance. Sioux women were skilled at  porcupine-quill and bead embroidery. The Sioux were resolute in resist�  ing white incursions. In 1862, white treaty violations led the Santee to  mount a bloody uprising under Little Crow; after their defeat, they were  forced onto reservations in South Dakota and Nebraska. Serious fighting  between U.S. troops and the Yankton and Teton Sioux in the 1860s and  �70s culminated in the Battle of the Little Bighorn in 1876, a great Indian  victory. Eventually, however, the Sioux surrendered and were forced onto  reservations. In 1890 the Ghost Dance religion inspired many Sioux to  take up arms, leading to the massacre at Wounded Knee. The Sioux num�  ber about 75,000.

Dec. 29, 1896, Chihuahua,  Mex.�d. Jan. 6, 1974, Cuernavaca) Mexican painter. A Marxist activist  from his youth, he fought in the Mexican Revolution alongside Venus-  tiano Carranza, who rewarded him by sponsoring his studies in Europe.  Back in Mexico (1922), he began his lifework of decorating public build�  ings with murals and organizing unions of artists and workers. With Diego  Rivera and Jose Clemente Orozco, he cofounded the renowned school of  Mexican mural painting. His activism interrupted his career several times  when he was imprisoned, chose self-imposed exile, and fought in the  Spanish Civil War. His murals are marked by great dynamism, monumen�  tal size and vigour, and a limited colour range subordinated to dramatic  effects of light and shadow. His easel paintings (e.g.. Echo of a Scream,  1937) helped establish his international reputation. In 1968 he became the  first president of the Mexican Academy of Arts.</p><p>Siracusa See Syracuse</p><p>Siren In Greek mythology, a creature, half bird and half woman, who lures  sailors to their doom with her sweet singing.

He became associated with Claude  Monet and Pierre-Auguste Renoir and with them became one of the  founders of Impressionism. His works, mostly landscapes, are distinguished  from those of his colleagues by their softly harmonious values. His fam�  ily was ruined by the Franco-Prussian War, and his life was a constant  struggle against poverty.

Living in his native Geneva from 1800, he wrote his His�  tory of the Italian Republics in the Middle Ages (1809-18), which inspired  the leaders of the Risorgimento. In his influential New Principles of Politi�  cal Economy (1819), he criticized capitalism and argued for regulation of  economic competition and for a balance between production and con�  sumption.

When gold was discovered  in the Black Hills in the mid-1870s, further outbreaks occurred. At the  Battle of the Rosebud, troops under Gen. George Crook were forced to  retreat; and at the Battle of Little Bighorn, Lt. Col. George Armstrong  Custer and his men were killed. In 1877 Sitting Bull led his followers into  Canada, but, with the buffalo reduced to near extinction, starvation even�  tually drove the Sioux to surrender. From 1883 Sitting Bull lived on Indian  Agency lands, at one point (1885) traveling with Buffalo Bill�s Wild West  Show. During the Ghost Dance movement, Sitting Bull was arrested. He  was killed when his warriors tried to rescue him.</p><p>situation comedy or sitcom Radio or television comedy series that  involves a continuing cast of characters in a succession of episodes. Often  the characters are markedly different types thrown together by circum�  stance and occupying a shared environment such as an apartment build�  ing or workplace. Typically half an hour in length and either taped in front  of a studio audience or employing canned applause, they are marked by  verbal sparring and rapidly resolved conflicts.</p><p>Sitwell family British family of writers. Edith Sitwell (1887-1964)  attracted attention when she joined her brothers in a revolt against Geor�  gian poetry. Her early work, which emphasizes the value of sound, includes  Clowns� Houses (1918) and Fagade (1923), set to music by William Wal�  ton. Beginning with Gold Coast Customs (1929), her style became less  artificial and experimental, and during World War II she emerged as a poet  of some emotional depth. Her later poetry is informed by religious sym�  bolism, as in Gardeners and Astronomers ( 1953) and The Outcasts (1962).  She was famous for her formidable personality, Elizabethan dress, and  eccentric opinions. Her brother Osbert (1892-1969) became famous, with  his siblings, as a tilter at establishment windmills in literature and the arts.  His best-known books are his memoirs, including Left Hand! Right Hand!  (1944) and Noble Essences (1950), which create with conscious nostalgia  the portrait of a vanished aristocratic age. Their brother Sacheverell (1897-  1988) is best known for his books on art, architecture, and travel. His  Southern Baroque Art (1924) was the forerunner of much academic  research. His poetry, including The People�s Palace (1918) and The Rio  Grande, was written mostly in traditional metres and reveals in its man�  nered style his interest in the arts and music.</p><p>Siva See Shiva  Sivaji See Shivaji</p><p>Siwa \'se-wo\ Oasis ancient Ammonium Oasis (pop., latest est.:  7,000), western Egypt. Located near the modem border with Libya, it is</p><p>6 mi (10 km) long and 4-5 mi (6-8 km) wide, with about 200 springs.  Extremely fertile, it supports thousands of date palms and olive trees. It  was the seat of the oracle temple of Amon; its fragmentary remains sur�  vive, with inscriptions dating from the 4th century bc, along with many  Roman remains.</p><p>Six Vses\, Les French "The Six" Group of young French composers  in the 1920s. Named by the critic Henri Collet (1885-1951), the group  was made up of Arthur Honegger, Darius Milhaud, Francis Poulenc,  Georges Auric (1899-1983), Louis Durey (1888-1979), and Germaine  Tailleferre (1892-1983). Their music represents a strong reaction against  German Romanticism, as well as against the lush style sometimes termed  Impressionism, exemplified by the work of Claude Debussy. Most of Les  Six were inspired by the iconoclastic music of Erik Satie, and they ben�  efited from the promotion of Jean Cocteau. They were only active as a  group for a few years.</p><p>Six-Day War or Arab-lsraeli War of T 967 War between Israel  and the Arab countries of Egypt, Syria, and Jordan. Palestinian guerrilla  attacks on Israel from bases in Syria led to increased hostility between the  two countries. A series of miscalculations by both sides followed. Syria  feared that an invasion by Israel was forthcoming and appealed to Egypt  for support. Egypt answered by ordering the withdrawal of UN peace�  keeping forces from the Sinai Peninsula and by moving troops into the area.  Amid increasingly belligerent language from both sides, Egypt signed a  mutual defense treaty with Jordan. Israel, surrounded and fearing an Arab  attack was imminent, launched what it felt was a preemptive strike against  the three Arab states on June 5, 1967. Israeli forces captured the Sinai  Peninsula, Gaza Strip, West Bank of the Jordan River, Old City of Jerus�  alem, and the Golan Heights. The status of these occupied territories sub�  sequently became a major point of contention between the two sides.</p><p>Six Dynasties (ad 220-589) In China, the period between the end of  the Han dynasty and the foundation of the Sui. The name is derived from  the six successive dynasties that had their capital at Nanjing: the Wu  (222-280), the Eastern Jin (317-420), the Liusong (420-479), the South�  ern Qi (479-502), the Southern Liang (502-557), and the Southern Chen  (557-589). During this period northern China was ruled by a succession  of kingdoms established by Central Asian invaders. Important among  these were the Northern Wei, Eastern Wei, Western Wei, Northern Qi, and  Northern Zhou. Despite the chaos of the age, great advances were made  in medicine, astronomy, botany, and chemistry. Buddhism and Daoism  became great popular religions, and the translation of Buddhist texts  focused Chinese attention on literature and calligraphy. Architecture and  the visual arts also bloomed during the period.</p><p>Sixtus IV orig. Francesco della Rovere (b. July 21, 1414, Celia  Ligure, near Savona, Republic of Genoa�d. Aug. 12, 1484, Rome) Pope  (1471-84). A Franciscan from Genoa, he enriched his family and the Papal  States through simony and heavy taxation. The Pragmatic Sanction of  Bourges caused strain with France, and Sixtus failed in his effort to unite  the Russian and Roman churches. He endorsed the Pazzi conspiracy,  though not the attempt to kill Lorenzo de'Medici. He also incited Venice to  attack Ferrara; then, in a turnabout, he placed Venice under interdict  (1483) as a rival to the Papal States. A patron of arts and letters, he built  the Sistine Chapel, which takes its name from him.</p><p>Sixtus V orig. Felice Peretti (b. Dec. 13,1520, Grottammare, Ancona,  Papal States�d. Aug. 27, 1590, Rome) Pope (1585-90). A dedicated  Franciscan and two-time inquisitor general of Venice, Sixtus was elected  pope at a time when the Papal States were in chaos. He suppressed brig�  andage and restored order using harsh measures that won him many  enemies. He raised vast sums through loans, taxes, and the sale of offices  and carried out an extensive building program in Rome. He defined the  Sacred College of Cardinals (1586), limiting the number of cardinals to  70, and his reforms of the Roman Curia (1588) lasted until the Second  Vatican Council. An energetic supporter of the Council of Trent, whose  decisions he implemented, Sixtus is recognized as one of the founders of  the Counter-Reformation. His foreign policy was aimed at combatting  Protestantism; he excommunicated the Protestant Henry of Navarre (later  Henry IV of France) and promised subsidies in return for a Spanish inva�  sion of England. He supported other Catholic rulers in Europe and mod�  erated his position toward Henry when it became apparent the future king  would convert to Catholicism.</p><p>Sjaelland \'she-,lan\ English Zealand Island, Denmark.

It has many Stone Age and Viking relics, including the Viking for�  tress of Traslleborg (c. 1000), as well as medieval churches, castles, and  manor houses. Grain and livestock farming, fishing, and tourism are major  industries.</p><p>Sjahrir Vsya-.rirV, Sutan (b. March 5, 1909, Padangpandjang, Sumatra,  Dutch East Indies�d. April 9, 1966, Zurich, Switz.) Indonesian nation�  alist and prime minister. He received a Dutch education and returned to  Indonesia, where he helped found a nationalist party in the 1930s. His  party, which favoured adopting Western constitutional democracy,  opposed that of Sukarno. He became prime minister after World War II,  stripping power from then-president Sukarno, whose collaboration with  the Japanese he feared would hurt the republic�s image internationally.  Sjahrir negotiated an agreement with the Dutch that established Indone�  sia�s authority in Sumatra and Java. Twice forced to resign (1946, 1947),  he then formed a socialist party (1948) that failed to win popular support.  Sukarno banned it in 1960, and Sjahrir was arrested and imprisoned; He  was allowed to travel to Switzerland shortly before his death.</p><p>Sjostrom Vshce-strcem\, Victor or Victor Seastrom (b. Sept. 20,  1879, Silbodal, Swed.�-d. Jan. 3,</p><p>1960, Stockholm) Swedish film  actor and director. Trained as a stage  actor, he directed and starred in his  first movie. The Gardener, in 1912.</p><p>With notable films such as Ingeborg  Holm (1913), The Outlaw and His  Wife (1918), and The Phantom Car�  riage (1921), he established the artis�  tic excellence of the Swedish silent  film in the post-World War I era. In  1923 he moved to Hollywood, where  he directed movies such as The Scar�  let Letter (1926) and The Wind  (1928). He returned to Sweden in  1930 and acted in numerous films,  notably Ingmar Bergman�s Wild  Strawberries (1957). Sjostrom�s  films are lyrically beautiful expressions of humanity�s relationship to  nature and to society.</p><p>skaldic \'skol-dik\ poetry Oral court poetry originating in Norway but  developed chiefly by Icelandic poets (skalds) from the 9th to the 13th  century. Skaldic poetry was contemporary with Eddie poetry (see Edda)  but differed from it in metre, diction, and style. Eddie poetry is anony�  mous, simple, and terse, often taking the form of an objective dramatic  dialogue. Skalds were identified by name. Their poems were descriptive,  occasional, and subjective, their metres strictly syllabic instead of free and  variable, and their language ornamented with similes and metaphors. For�  mal subjects were the mythical stories engraved on shields, praise of  kings, epitaphs, and genealogies.</p><p>Skanderbeg Vskan-dor-.begV orig. George Kastrioti (b. 1405,  northern Albania�d. Jan. 17, 1468, Lezhe) Albanian leader. Son of the  prince of Emathia, he was given early as a hostage to the Turkish sultan.  He converted to Islam, served in the Turkish army, and was given the  name Iskander and the rank of bey. In 1443 he abandoned the Turkish  service, joining his Albanian countrymen in opposition to the Turks and  returning to the Christian faith. He then organized a league of Albanian  princes and was elected commander in chief. In 1444-66 he repulsed 13  Turkish invasions; his defeat of Murad II�s armies in 1450 made him a  hero in the Western world. After his death, however, Albania soon became  part of the Ottoman Empire. Skanderbeg is regarded as the national hero  of Albania.</p><p>skandha Vskon-doV Pali khandha In Buddhism, any of the five ele�  ments that constitute an individual�s mental and physical existence. They  are rupa (physical matter), vedana (feeling), samjna (perception; Pali  sanna), samskara (mental formations; Pali sankhara), and vijnana (con�  sciousness; Pali vinnana). The four mental aggregates are perceived to be  the personality or ego but are in fact only processes in a state of continuous  change, subject to the effects of karma. At death the mental skandha s dis�  sociate from the rupa and find a new physical base, resulting in a new birth.</p><p>Skara Brae Vska-ra-'bra\ or Skerrabra Late Neolithic village on the  shore of the Bay of Skaill in Scotland�s Orkney Islands. Skara Brae was  built c. 3200-2200 bc. Covered by a sand dune, it is one of the most per�  fectly preserved ancient villages of Europe. Its excavation, begun in the  1860s, revealed huts of undressed, mortarless stone slabs containing stone  furniture. They were linked by paved alleys; some had been covered by  banking them with mixed sand, peat ash, and refuse, becoming stone-  roofed tunnels. A sewer drained the whole. Inhabitants lived on the flesh  and milk of their cattle and on shellfish; they probably wore skins. For  tools they used local stone, beach pebbles, and animal bones. They wore  pendants and coloured beads of sheep marrow, cows� teeth, killer-whale  teeth, and boars� tusks. Lozenges and similar rectilinear patterns were  scratched on hut walls and along alleys. Pottery vessels show incised and  relief designs, including the only example of a true spiral known from  prehistoric Britain.</p><p>skarn In geology, a metamorphic zone developed in the contact area  around igneous rock intrusions when carbonate sedimentary rocks are  invaded by and replaced with chemical elements that originate from the  igneous rock mass nearby. Many skams also include ore minerals; produc�  tive deposits of copper or other base metals have been found in and adja�  cent to skarns. The typical rock of a skarn is homfels, a fine-grained, flinty  rock produced by the heat and solutions given off by the intruding magma.</p><p>skate Any of nine genera (suborder Rajoidea) of rounded to diamond�  shaped rays. These bottom-dwellers are found from tropical to near-Arctic  waters and from the shallows to depths of more than 9,000 ft (2,700 m).  Most have spines on the upper surface, and some have weak electrical  organs in their long, slender tails. Skates lay oblong, leathery eggs (called  mermaid�s purses), which are often found on beaches. Species vary from  20 in. (50 cm) to 8 ft (2.5 m) long. They swim with an undulating move�  ment of their pectoral fins. They trap active mollusk, crustacean, and fish  prey by dropping down on them from above. Skates� �wings� are edible.</p><p>skateboarding Form of recreation, popular among youths, in which a  person rides standing balanced on a small board mounted on wheels. The  skateboard first appeared in the early 1960s on paved areas along Califor�  nia beaches as a makeshift diversion for surfers when the ocean was flat. In  the 1970s a faster, polyurethane wheel was developed. Eventually skate�  board parks were built, providing a variety of slopes and banked surfaces  for sudden turns and flamboyant stunts. The skateboarding craze contrib�  uted to the emergence of snowboarding as a winter youth sport.</p><p>skating Sport in which bladelike runners or sets of wheels attached to  shoes are used for gliding on ice or on surfaces other than ice.

The sport of skel�  eton sledding developed in the 1880s on the famed Cresta Run at Saint  Moritz, Switz. The �bony� look of the early sleds gave the sport its name.  Riders attain speeds of more than 80 miles (129 km) per hour. It was first  contested at the Olympic games in 1928.</p><p>Skelton, John (b. c. 1460�d. June 21, 1529, London, Eng.) English  poet.

(1522) were directed against Cardinal Wolsey and human�  ist learning.</p><p>Skelton, Red orig. Richard Bernard Skelton (b. July 18, 1913,  Vincennes, Ind., U.S.�d. Sept. 17, 1997, Rancho Mirage, Calif.) U.S.  comic actor. He joined a touring medicine show at age 10, performed in  minstrel shows, burlesque, and vaudeville, and was a hit on Broadway in  1937 with his trademark doughnut-dunking pantomime. His 1938 screen  debut was followed by appearances in more than 35 film comedies. He  starred in the popular The Red Skelton Show on radio (1941-44, 1945-</p><p>53) and television (1951-71). Noted for his broad humour and warm per�  sonality, Skelton developed characters such as the Mean Widdle Kid,  Clem Kadiddlehopper, and Freddie the Freeloader.</p><p>skene \'ske-ne\ In ancient Greek theatre, a building behind the playing  area that was originally a hut in which actors changed masks and cos�  tumes. It eventually became the scenic backdrop for the drama. First used  c. 465 bc, the skene was a small wooden structure facing the circle of  spectators. It developed into a two-story edifice decorated with columns,  with three doors used for entrances and exits. It was flanked by wings  {paraskenia). By the end of the 5th century bc, the wooden skene was  replaced by a permanent stone structure. In the Roman theatre it was an  elaborate building facade.</p><p>skepticism Philosophical doubting of knowledge claims in various  areas. From ancient to modern times, skeptics have challenged accepted  views in metaphysics, science, morals, and religion. Pyrrhon of Elis (c.  360-272 bc) sought mental peace by avoiding commitment to any par�  ticular view; his approach gave rise in the 1st century bc to Pyrrhonism,  proponents of which sought to achieve suspension of judgment by sys�  tematically opposing various knowledge claims. One of its later leaders,  Sextus Empiricus (2nd or 3rd century ad), strove for a state of imper�  turbability. Modern skeptical philosophers include Michel de Montaigne,  Pierre Bayle, and David Hume.</p><p>ski jumping Skiing event in which contestants ski down a steep ramp  curved upward at the end and launch themselves into the air for distance.  Using a crouch position, skiers can achieve ramp speeds of 75 mi (120  km) per hour. After takeoff, they lean far forward from the ankles with  knees straight and skis held open at the tips to form a V, a position that  minimizes wind resistance and maximizes lift. Scoring is based partly on  distance and partly on form.</p><p>skiing Sport and mode of transportation involving moving over snow  on a pair of long flat runners (skis) attached to shoes or boots. Skiing was  born in northern Europe; the oldest skis, found in Russia, are some 6,000  years old. The earliest skis were often short and broad. The first written  references to skiing come from the Han dynasty (206 bc-ad 220) and  describe skiing in northern China. Skiing was used in warfare in Scan�  dinavia from the 13th century or earlier to the 20th century. The earliest  mode of skiing developed into the sport now called cross-country skiing.  Competitive cross-country skiing began in Norway in the 1840s and had  reached California by the 1860s. Improvements on primitive bindings c.  1860 led to greater popularity of recreational skiing. Ski-jumping compe�  titions date from the 1870s. Downhill skiing was limited by the need to  climb the hill before or after skiing down; the building of ski lifts began  in the 1930s. Skis were originally made of a single piece of wood, usu�  ally hickory; laminated construction began in the 1930s, plastic running  surfaces were introduced in the 1950s, and no wood has been used in the  construction of downhill skis for several decades. The business of skiing  began its serious growth in the 1930s and became explosive in the 1950s  and �60s; huge resorts now dot the Austrian, Swiss, and Italian Alps, the  Rocky Mountains, and other mountainous regions. See also Alpine skiing.</p><p>skimmer Any of three species (family Rynchopidae) of waterbirds hav�  ing a red bladelike bill, with the lower mandible longer than the upper.  Skimmers live chiefly in estuaries and along wide rivers in warm regions.  At twilight, they skim calm, shallow water with the open bill tip sub�  merged; when a fish or crustacean is hit, the upper mandible snaps down.  Skimmers are dark above with white underparts, face, and forehead, red  legs, and black wings. The American black skimmer ( Rynchops nigra )  grows to 20 in. (50 cm) long.</p><p>skin Surface covering of the body that protects it and receives external  sensory stimuli, consisting of an epidermis over a thicker dermis. The  epidermis contains cells involved in immune defenses, sensory receptors,  pigment cells, and KERATiN-producing cells. The last harden and migrate to  the surface to form a dead, relatively dry outer layer of horny tissue that  constantly sloughs away. The dermis contains sensory nerves and blood  vessels within connective tissue. Collagen and elastin fibres give skin its  tough, elastic quality. Cells scattered through it produce its components  and take part in immune and other skin responses. A fat layer under the  dermis provides nutritional storage, cushioning, and insulation. Skin dis�  orders range from dermatitis and acne to skin cancer. Changes in skin colour  (e.g., jaundice) or texture may be clues to systemic disorders.

The tough, dead cells of the outer epidermal surface  (corneal layer) serve as a physical barrier and are continually replaced by cells  produced in the basal layer. The thick supportive layer of dermis contains nerve  endings, blood vessels, sweat glands, hair follicles, and oil glands. The hair follicle  encloses the root of the hair. Oil glands associated with hair follicles secrete an oily  substance (sebum) which lubricates the skin surface. The watery secretions of the  tubular sweat glands are released onto the skin's surface through small pores. A  layer of fat cells lies below the dermis.</p><p>� MERRIAM-WEBSTER INC.</p><p>skin cancer Malignant tumour of the skin, including some of the most  common human cancers. Though recognizable at an early stage, it has a  significant death rate. Light-skinned people have the highest risk but can  reduce it by limiting exposure to sunlight and to ionizing radiation. The  most common types arise in the epidermis (outer skin layer) and have  become more frequent with the thinning of the atmosphere�s ozone layer.  The most serious form is melanoma, which is frequently fatal if not treated  early with surgery. Cancers arising from the dermis are rare; the best-  known is Kaposi sarcoma.</p><p>skinhead Member of an international youth subculture characterized  by hair and dress styles evoking aggression and physical toughness.

Launched into Earth orbit in 1973 on a  Saturn V rocket, it used as its main habitat the vehicle�s third stage, which  had been outfitted as a workshop. Its apparatus included a powerful solar  telescope and equipment for Earth- and materials-sciences research and  for studies of the human body�s adaptation to weightlessness. Three suc�  cessive astronaut crews conducted research aboard Skylab for a total of  171 days in 1973-74. Because its thermal shielding was damaged during  launch, its first crew took up and installed an improvised sunshade to pre�  vent the station from seriously overheating. Although plans called for  Skylab to be reused, increased solar activity caused its orbit to degrade  faster than expected. In 1979 it entered Earth�s atmosphere and broke up,  with debris spreading over the southeastern Indian Ocean and a sparsely  populated section of Western Australia.</p><p>skylark Species ( Alaudci arvensis) of Old World lark particularly noted  for its rich, sustained song and for singing in the air.

Skylights have found wide application  admitting steady, even light in industrial, commercial, and residential  buildings, especially those with a northern orientation. Installations range  from purely functional daylighting to elaborate aesthetic forms. Flat-  roofed buildings may have domed skylights; in others the skylight fol�  lows the slope of the roof. Often the skylight, or a portion of it, functions  as an operating window to admit air.</p><p>skyscraper Very tall multistoried building. The term originally applied  to buildings of 10-20 stories, but now generally describes high-rises of  more than 40-50 stories. James Bogardus (1800-1874) built the pioneer�  ing Cast Iron Building, New York (1848), with a rigid iron frame provid�  ing the main support for upper-floor and roof loads. The refinement of the  Bessemer process for making steel (lighter and stronger than iron) made  extremely tall buildings possible. Chicago�s Home Insurance Co. Build�  ing (1884-85), by William Le Baron Jenney (1832-1907), was the first  tall building to use a steel skeleton. Structurally, skyscrapers consist of a  substructure supported by a deep foundation of piles or caissons beneath  the ground, an aboveground superstructure of columns and girders, and a  curtain wall hung on the structural framework. Tube structures, braced  tubes, and trussed tubes were developed to give skyscrapers the ability to  resist lateral wind and seismic forces. The bundled-tube system, devel�  oped by Fazlur Khan (1928-1982), uses narrow steel tubes clustered  together to form exceptionally rigid columns, and has been used to build  some of the world�s tallest skyscrapers (e.g.. Sears Tower). Skyscraper  design and decoration have passed through several stages: Louis Sullivan  emphasized verticality; the firm of Me Kim, Mead, &amp; White (see Charles  F. McKim, Stanford White) stressed Neoclassicism. The International Style  was ideally suited to skyscraper design. Originally a form of commercial  architecture, skyscrapers have increasingly been used for residential pur�  poses as well.

It includes newly coined words, shortened forms, and  standard words used playfully out of their usual context. Slang is drawn  from the vocabularies of limited groups: cant, the words or expressions  coined or adopted by an age, ethnic, occupational, or other group (e.g.,  college students, jazz musicians); jargon, the shoptalk or technical termi�  nology specific to an occupation; and argot, the cant and jargon used as  a secret language by thieves or other criminals. Occupying a middle  ground between standard and informal words accepted by the general  public and the special words or expressions of these subgroups, slang  often serves as a testing ground for words in the latter category. Many  prove either useful enough to become accepted as standard or informal  words or too faddish for standard use. Blizzard and okay have become  standard, while conbobberation (�disturbance�) and tomato (�girl�) have  been discarded.

Slapstick comedy became popular in 19th-century music halls  and vaudeville theatres and was carried into the 20th century by silent-  movie comedians such as Charlie Chaplin, Harold Lloyd, and Mack Sen-  nett�s Keystone Kops and later by Laurel and Hardy, the Marx Brothers,  and the Three Stooges.</p><p>slate Fine-grained, clayey metamorphic rock that splits readily into thin  slabs that have great tensile strength and durability.

They live chiefly in eastern and southeastern  Europe but also extend across northern Asia to the Pacific. Slavs are cus�  tomarily subdivided into eastern Slavs (Russians, Ukrainians, and Belaru�  sians), western Slavs (Poles, Czechs, Slovaks, and Wends, or Sorbs), and  southern Slavs (Serbs, Croats, Bulgarians, Slovenes, and Macedonians).  Historically, western Slavs were integrated into western Europe; their  societies developed along the lines of other western European nations.  Eastern and southern Slavs suffered Mongol and Turkish invasions and  evolved more autocratic, state-centred forms of government. Religion  (mainly Eastern Orthodoxy and Roman Catholicism) divides Slavs, as  does the use of the Cyrillic and Latin alphabets. In the Middle Ages, Slavic  polities that left a rich cultural heritage developed in Bohemia, Poland,  Croatia, Bosnia, Serbia, and Bulgaria, but, by the end of the 18th century,  all these states had been absorbed by powerful neighbours (the Ottoman  Empire, Austria, Hungary, Prussia, Russia). Eastern Slavic history often  was marked by unsuccessful attempts to repel Asian invaders. In the 16th  century, Muscovy (later Russia) embarked on a course of expansion across  northern and central Asia that eventually made it the most powerful Slavic  state. Pan-Slavism in the 19th century had some influence on the forma�  tion of the new Slavic states after World War I, though Czechoslovakia  and Yugoslavia�the two attempts to integrate different Slavic peoples  into single polities�had both disintegrated by the end of the 20th cen�  tury, one peacefully and the other violently.</p><p>Slave Acts, Fugitive See Fugitive Slave Aas</p><p>slave code In U.S. history, law governing the status of slaves, enacted  by those colonies or states that permitted slavery. Slaves were considered  property rather than persons. They had few legal rights: in court, their  testimony was inadmissible in cases involving whites; they could make  no contract nor own any property; they could not strike a white person,  even if attacked by one; they could not be away from their owner�s pre�  mises without permission; they could not assemble unless a white person  was present; they could not be taught to read or write; and they were not  permitted to marry. Offenders were subject to severe punishment, includ�  ing whipping, branding, imprisonment, and death.

A Narrative of the Uncommon Sufferings and Surpris�  ing Deliverance of Briton Mammon, a Negro Man (1760) is often con�  sidered the first example. The first slave narrative to become an  international best-seller was the two-volume Interesting Narrative of the  Life of Olaudah Equiano, or Gustavus Vassa, the African (1789), but evi�  dence turned up at the outset of the 21st century suggests that the author  was born in South Carolina rather than Africa�i.e., that at least part of  the work is not autobiographical. The major period of slave narratives  was 1830-60. Some were factual autobiographies, while others were  influenced or sensationalized by the writer�s desire to arouse sympathy  for the abolitionist cause. The genre reached its height with the autobi�  ography of Frederick Douglass (1845). In the 20th century, documentary  narratives were compiled from recorded interviews with former slaves.</p><p>Slave River River, northern Alberta and southern Northwest Territo�  ries, Canada.

Slavery has  existed throughout the world from ancient times, and trading in slaves has  been equally universal. Slaves were taken from the Slavs and Iranians  from antiquity to the 19th century, from the sub-Saharan Africans from  the 1st century ad to the mid-20th century, and from the Germanic, Celtic,  and Romance peoples during the Viking era. Elaborate trade networks  developed: for example, in the 9th and 10th centuries, Vikings might sell  East Slavic slaves to Arab and Jewish traders, who would take them to  Verdun and Leon, whence they might be sold throughout Moorish Spain  and North Africa. The transatlantic slave trade is perhaps the best-known.  In Africa, women and children but not men were wanted as slaves for  labour and for lineage incorporation; from c. 1500, captive men were  taken to the coast and sold to Europeans. They were then transported to  the Caribbean or Brazil, where they were sold at auction and taken  throughout the New World.

Slavery has existed on nearly every continent, including Asia, Europe,  Africa, and the Americas, and throughout most of recorded history. The  ancient Greeks and Romans accepted the institution of slavery, as did the  Mayas, Incas, Aztecs, and Chinese. Until European involvement in the  trade, however, slavery was a private and domestic institution. Beginning  in the 16th century, a more public and �racially� based type of slavery  was established when Europeans began importing slaves from Africa to  the New World (see slave trade). An estimated 11 million people were  taken from Africa during the transatlantic slave trade. By the mid-19th  century the slave population in the U.S. had risen to more than four mil�  lion, although slave imports had been banned from 1809. Most of the  Africans sent to the United States worked on cotton or rice plantations in  the South, their status governed by slave codes. Almost 40 percent of cap�  tives transported from Africa to the Americas were taken to Brazil, where  harsh conditions required the constant replenishing of slaves. Following  the rise of abolitionism, Britain outlawed slavery in its colonies in 1833,  and France did the same in 1848. During the American Civil War, slavery  was abolished in the Confederacy by the Emancipation Proclamation  (1863), which was decreed by Pres. Abraham Lincoln. Brazil was the last  to abolish slavery, doing so in 1888. Official policy notwithstanding, sla�  very continues to exist in many parts of the world. Many contemporary  slaves are women and children forced into prostitution or working at hard  labour or in sweatshops. Debt bondage is common, affecting millions of  people, and slaves are often traded for material goods.

The Slavic  family is usually divided into three subgroups: West Slavic, comprising  Polish, Slovak, Czech, and Sorbian; East Slavic, comprising Russian, Ukrai�  nian, and Belarusian; and South Slavic, comprising Slovene, Serbo-  Croatian, Bulgarian, and Macedonian. Polish belongs to the Lekhitic  subgroup of West Slavic languages, which also includes Kashubian�now  spoken in western Poland by fewer than 150,000 people and regarded in  Poland as a Polish dialect�and several now-extinct languages. A distinc�  tive feature of this subgroup is its preservation of the Proto-Slavic nasal  vowels. Another remnant language is Sorbian, spoken by 60,000-70,000  people in eastern Germany. Western Lekhitic and Sorbian are all that  remains of what was once a much greater Slavic speech area in central  Europe; that area was gradually Germanized from about the 9th century.  Among Indo-European languages, Slavic is closest to the family of Bal�  tic LANGUAGES.</p><p>Slavic religion Beliefs and religious practices of the ancient Slavic  peoples of East Europe, including the Russians, Ukrainians, Poles,  Czechs, Slovaks, Serbs, Croats, and Slovenes. Most Slavic mythologies  hold that God ordered the devil to bring up a handful of sand from the  bottom of the sea and created the land from it. Slavic religion was often  characterized by dualism, with a Black God named in curses and a White  God invoked to obtain protection or mercy. Lightning and fire gods were  also common. The ancient Russians appear to have erected their idols  outdoors, but the Baltic Slavs built temples and enclosed sacred places,  where festivals were held and animal and human sacrifices occurred. Such  festivals also often included communal banquets at which the flesh of  sacrificial animals was consumed.</p><p>Slavonia Historical region, Croatia. It lay between the Sava River on  the south and the Drava and Danube rivers on the north and east. It was  included in the kingdom of Croatia in the 10th century.

Prominent in the 1840s and �50s, the Slavophiles  believed in the uniqueness of Russian culture and contended that Russia  should rely on its own character and history to determine its future devel�  opment. They hoped to restore the autocracy and the church to their ideal  forms before Peter I (the Great) introduced Western reforms, and they also  favoured emancipation of the serfs and freedom of speech and the press.  The Slavophile movement declined in the 1860s, but its principles were  adapted and simplified by extreme nationalists, advocates of Pan-Slavism,</p><p>and revolutionary Narodniks (Populists). It was opposed by the Western�  izers, who viewed western Europe as a model for Russian modernization.</p><p>sled dog Any working dog used to pull a sled carrying people and sup�  plies across snow and ice.

Humans normally sleep at night, whereas  nocturnal species sleep during the day. The average human sleep require�  ment is about 7.5 hours. Sleep is divided into two main types, REM  (rapid-eye-movement) and NREM (non-REM); each recurs cyclically  several times during a normal period of sleep. REM sleep is character�  ized by increased neuronal activity of the forebrain and midbrain, by  depressed muscle tone, and by dreaming (see dream), rapid eye move�  ments, and vascular congestion of the sex organs. NREM sleep is divided  into four stages, the last of which is the deep, restorative, quiet sleep  commonly associated with �a good night�s rest.� See also insomnia, nar�  colepsy.</p><p>sleeping sickness Protozoal disease transmitted by the bite of the tsetse  fly. Two forms, caused by different species of the genus Trypanosoma,  occur in separate regions in Africa. The parasite enters the bloodstream  and invades the lymph nodes and spleen, which become swollen, soft, and  tender. Irregular fever and delayed pain sensation develop. In the Rhode�  sian form, the patient soon dies of massive toxemia. The Gambian type  progresses to brain and spinal cord invasion, causing severe headache,  mental and physical fatigue, spastic or flaccid paralysis, chorea, and pro�  found sleepiness, followed over two or three years by emaciation, coma,  and death. Some patients develop a tolerance but still carry the trypano�  somes. The earlier drug treatment begins, the greater the chance of recov�  ery.

Origi�  nally grouped within the kingdom Fungi, some classification systems  consider slime molds to be in the kingdom Protista. They typically thrive  in dark, cool, moist conditions such as on forest floors. Bacteria, yeast,  molds, and fungi provide the main source of slime-mold nutrition. The  complex life cycle of slime molds, exhibiting complete alternation of  generations, may clarify the early evolution of both plant and animal cells.  In the presence of water a tiny spore releases a mass of cytoplasm called  a swarm cell, which later develops into an amoebalike creeping cell called  a myxamoeba. Both swarm cells and myxamoebas can fuse in sexual  union; the resulting fertilized cell, or plasmodium, grows through nuclear  division and forms a spore case, which, when it dries, disintegrates and  releases spores to begin the cycle again.</p><p>slippery elm or red elm Large-leaved elm (Ulmus rubra or U.fulva )  of eastern North America that has hard wood and fragrant inner bark.

His Thesaurus of Scales and Melodic  Patterns (1947) was an inspiration to numerous composers. He edited four  editions of Baker�s Dictionary of Music and Musicians (1958-92). His  commodious scholarship was undertaken with zest and humour, and near  the end of his long life he was lionized by Frank Zappa and other musi�  cians.</p><p>slope Numerical measure of a line�s inclination relative to the horizontal.  In analytic geometry, the slope of any line, ray, or line segment is the ratio  of the vertical to the horizontal distance between any two points on it  (�slope equals rise over run�). In differential calculus, the slope of a line tan�  gent to the graph of a function is given by that function�s derivative and rep�  resents the instantaneous rate of change of the function with respect to  change in the independent variable. In the graph of a position function (rep�  resenting the distance traveled by an object plotted against elapsed time),  the slope of a tangent line represents the object�s instantaneous velocity.</p><p>English slipware dish by Thomas Toft of  northern Staffordshire, c. 1680; in the  Victoria and Albert Museum, London</p><p>COURTESY OF THE VICTORIA AND ALBERT MUSEUM,  LONDON</p><p>sloth Nocturnal, solitary, tree-dwelling mammal (family Bradypodidae),  found in South and Central America.</p><p>About 2 ft (60 cm) long, sloths have  a tiny tail, peglike teeth, long curved  claws, and long forelimbs.

Slovak was virtually  an unwritten language until the late 18th century, largely because of the  long political domination of Slovakia by Hungary and the much earlier  literary cultivation of Czech, Slovak�s western linguistic neighbour.  Present-day literary Slovak was effectively consolidated by the 1850s on  the basis of Central Slovak dialects.</p><p>Slovakia officially Slovak Republic Country, central Europe.

It  remained in the kingdom of Hungary until the end of World War I, when  the Slovaks joined the Czechs to form the new state of Czechoslovakia  in 1918. In 1938 Slovakia was declared an autonomous unit within  Czechoslovakia; it was nominally independent under German protection  from 1939 to 1945. After the expulsion of the Germans, Slovakia joined  a reconstituted Czechoslovakia, which came under Soviet domination in  1948. The fall of the communist regime in 1989 led to a revival of inter�  est in autonomy, and Slovakia became an independent nation in 1993.

The oldest Slavic text in the Latin alphabet, the Freising Frag�  ments (c. 1000), are written in a very early form of Slovene; the language  is not attested again until the 16th century, when Lutheran reformers  translated the Bible into Slovene. The language has a remarkable degree  of dialect diversity considering the size of its speech area, probably  enhanced by the country�s Alpine geography and long period of domina�  tion by non-Slovene-speaking rulers.</p><p>Slovenia officially Republic of Slovenia Country, northwestern  Balkans region, southern Europe.

Religion: Christianity (pre�  dominantly Roman Catholic; also other  Christians). Currency: Slovene tolar. Slov�  enia is predominantly mountainous and</p><p>wooded, with deep, fertile valleys and numerous rivers. It is one of the  more prosperous regions of the Balkans. Its economy is based largely on  manufacturing; coal, lead, and zinc are mined, but forestry, livestock, and  crops, including potatoes, grains, and fruits, are also important. Slovenia  is a republic with two legislative houses; its head of state is the president,  and the head of government is the prime minister. The Slovenes settled  the region in the 6th century ad. In the 8th century it was incorporated  into the Frankish empire of Charlemagne, and in the 10th century it came  under Germany as part of the medieval empire (later the Holy Roman  Empire). Except for the period from 1809 to 1813, when Napoleon ruled  the area, most of the lands belonged to Austria until the formation of the  Kingdom of Serbs, Croats, and Slovenes in 1918. Slovenia became a con�  stituent republic of Yugoslavia in 1946 and received a section of the former  Italian Adriatic coastline in 1947. In 1990 Slovenia held the first contested</p><p>multiparty elections in Yugoslavia since before World War II. In 1991  Slovenia seceded from Yugoslavia; its independence was internationally  recognized in 1992.</p><p>slug Any species of gastropod that glides along on a broad tapered foot  and has no shell or one that is merely an internal plate or a series of gran�  ules. Most slugs use the mantle cavity (see mollusk) as a lung. Slugs have  a soft, slimy body and live in moist habitats on land (except for one fresh�  water species). All are hermaphroditic. In temperate regions, the common  slugs eat fungi and decaying leaves. Some tropical species eat plants, and  some European species eat other snails and earthworms.

Rapid  industrialization in 19th-century Europe was accompanied by rapid popu�  lation growth and the concentration of working-class people in over�  crowded, poorly built housing. England passed the first legislation for  building low-income housing to certain minimum standards in 1851; laws  for slum clearance were first enacted in 1868. In the U.S., slum develop�  ment coincided with the arrival of large numbers of immigrants in the late  19th and early 20th centuries; laws concerning adequate ventilation, fire  protection, and sanitation in urban housing were passed in the late 1800s.  In the 20th century government and private organizations built low-  income housing and appropriated funds for urban renewal and offered  low-interest home loans. Shantytowns, which often grow up around urban  centres in developing countries as rural populations migrate to the cities  in search of employment, are one type of slum for which alleviating mea�  sures have yet to be successfully introduced.

The autonomic nervous system supplies it with para�  sympathetic nerves that initiate peristalsis and sympathetic nerves that  suppress it. It is lined with minute fingerlike projections (villi) that greatly  increase its surface area for enzyme secretion and food absorption.

It is steered by fins or wings on the bomb that move in response  to guidance commands. Guidance systems may be electro-optical, laser,  infrared, or inertial. Electro-optical systems send pictures of the area so  that the bomb can be guided onto the target. Laser-guided bombs follow  the reflections of a laser beam trained onto the target by an aircraft or a  spotter on the ground. Infrared guidance responds to radiation generated  by warm areas of the target. Inertial navigation is based on inputting  coordinates derived from radar systems or from Global Positioning Sys�  tem satellites into the bomb�s gyroscopes.

He constructed the great Forth and Clyde Canal  in Scotland; built bridges at Perth, Banff, and Coldstream; and completed  the harbour at Ramsgate, Kent. He was a leader in the transition from  wind-and-water to steam power; with his improvements, Thomas New�  comen�s atmospheric steam engine achieved its maximum performance. He  designed atmospheric pumping engines for collieries, mines, and docks.  In 1771 he founded the British Society of Civil Engineers (now the  Smeatonian Society). He is regarded as the founder of the civil engineer�  ing profession in Britain.</p><p>smelt Any of certain slender, silvery, carnivorous, food fishes (family  Osmeridae) having a small fleshy fin. Smelts live in cold northern seas,  and most species spawn a short distance upstream. The American smelt  {Osmerus mordax), introduced from the Atlantic to the Great Lakes, is the  largest smelt, about 15 in. (38 cm) long. The European smelt (O. eper-</p><p>lanus ) is similar. Among Pacific species are the rainbow herring, capelin,  and eulachon, or candlefish, which is so oily at spawning time that it can  be dried and burned as a candle. Silversides (see grunion) and other unre�  lated fishes are sometimes called smelts.</p><p>smelting Process by which a metal is obtained from its ore, either as the  element or as a simple compound, usually by heating beyond the melting  point, ordinarily in the presence of reducing agents such as coke or oxi�  dizing agents such as air (see oxidation-reduction). A metal whose ore is  an oxygen compound (e.g., iron, zinc, or lead oxide) is heated (reduction  smelting) in a blast furnace to a high temperature; the oxide combines with  the carbon in the coke, escaping as carbon monoxide or carbon dioxide.  Other impurities are removed by adding flux, with which they combine  to form slag. If the ore is a sulfide mineral (e.g., copper, nickel, lead, or  cobalt), air or oxygen is blasted through (matte smelting) to oxidize the  sulfide to sulfur dioxide and any iron to oxide slag, leaving the metal.

He was determined to become a pianist, but his first concert (1847)  ended his hopes, and he thereafter taught music, opening two schools of  music. In the 1860s he turned to opera, becoming conductor of the  national theatre in 1866. His second opera was The Bartered Bride (1866),  which gained lasting success after many revisions. Dalibor (1868) fol�  lowed and also became popular; he would complete five more operas.  Though rendered deaf by syphilis in 1874, in his last decade he wrote  some of his most beloved music, including the cycle My Country (1874-  79), which included the famous symphonic poem The Moldau, and the  quartet From My Life (1876). He became insane in 1883 and died in an  asylum.

The son of a customs official, he studied at the Universities of Glasgow  and Oxford. A series of public lectures in Edinburgh (from 1748) led to  a lifelong friendship with David Hume and to Smith�s appointment to the  Glasgow faculty in 1751. After publishing The Theory of Moral Senti�  ments (1759), he became the tutor of the future Duke of Buccleuch (1763�  66); with him he traveled to France, where Smith consorted with other  eminent thinkers. In 1776, after nine years of work, Smith published An  Inquiry into the Nature and Causes of the Wealth of Nations, the first  comprehensive system of political economy. In it he argued in favour of  an economic system based on individual self-interest that would be led,  as if by an �invisible hand,� to achieve the greatest good for all, and pos�  ited the division of labour as the chief factor in economic growth. A reac�  tion to the system of mercantilism then current, it stands as the beginning  of classical economics. The Wealth of Nations in time won him an enor�  mous reputation and would become virtually the most influential work on  economics ever published. Though often regarded as the bible of capital�  ism, it is harshly critical of the shortcomings of unrestrained free enter�  prise and monopoly. In 1777 Smith was appointed commissioner of  customs for Scotland, and in 1787 rector of the University of Glasgow.</p><p>Smith, Alfred E(manuel) (b. Dec. 30, 1873, New York, N.Y.,  U.S.�d.

She began recording in 1923 and appeared in the film  St. Louis Blues (1929). Her interpretations represent the fully realized  transition of the rural folk tradition of the blues to its urbane structure and  expressiveness. A bold, supremely confident artist with a powerful voice  and precise diction, she became known as �Empress of the Blues.� Smith  was the most successful African American entertainer of her time.

U.S. sculptor. He learned to work with metal  while employed at an automobile plant. In 1926 he went to New York  City and took various jobs while studying painting at the Art Students  League. His sculptures grew out of his abstract paintings, to which he  attached so many bits of wood, metal, and found objects that they became  virtual bases for sculptural superstructures. He became the first U.S. art�  ist to make welded metal sculpture. In 1940 he moved to Bolton Land�  ing, N.Y., and there made his large yet seemingly weightless metal  sculptures until his death in a car crash. His abstract biomorphic and geo�  metric forms are remarkable for their erratic inventiveness, stylistic diver�  sity, and high aesthetic quality.

U.S. singer, long  known as the �First Lady of Radio.� Smith studied nursing before mov�  ing to New York City, where she won a Broadway role as an overweight  girl who was the butt of jokes. In 1931 she began her immensely popular  radio show Kate Smith Sings, which ran for 16 years; her theme song,  �When the Moon Comes over the Mountain,� became familiar to mil�  lions. In 1938 she created the news and gossip program Kate Smith Speaks  and introduced Irving Berlin's song �God Bless America.� She hosted sev�  eral television shows in the 1950s. In 1982 she was awarded the U.S.  Medal of Freedom.</p><p>Smith, Dame Maggie orig. Margaret Natalie Smith (b. Dec.  28, 1934, Ilford, Essex, Eng.) British actress. She first gained recognition  on Broadway in New Faces of 1956, and, after winning praise for her  roles in The Rehearsal (1961) and Mary, Mary (1963), she joined Brit�  ain�s National Theatre Company, where she starred opposite Laurence  Olivier in Othello (1964; film, 1965). Her later films include The Prime  of Miss Jean Brodie (1969, Academy Award), Travels with My Aunt  (1972), California Suite (1978, Academy Award), and The Lonely Pas�  sion of Judith Hearne (1987). Known for her nervous intensity, acid wit,  and flawless timing, she has many great stage performances to her credit,  notably in The Way of the World (1985) and Lettice and Lovage (1990,  Tony Award).</p><p>Smith, Margaret Chase orig. Margaret Madeline Chase (b.</p><p>Dec. 14, 1897, Skowhegan, Maine, U.S.�d. May 29, 1995, Skowhegan)  U.S. politician. She served as secretary to her husband, Clyde Smith, after  he was elected to the U.S. House of Representatives as a Republican in  1936. When he suffered a heart attack in 1940, he urged voters to elect  her to the office. She became the first woman to win election to both the  House (1940�49) and the Senate (1949-73). Though a staunch anticom�  munist, she was the first Republican senator to condemn the tactics of  Joseph McCarthy, delivering a memorable �Declaration of Conscience�  speech on the Senate floor in 1950. Her opinion that Pres. John F. Kennedy  should use nuclear weapons against the Soviet Union prompted Soviet  leader Nikita Khrushchev to dub her �the devil in disguise of a woman.�  She retired from politics after her defeat in 1972. She received the Presi�  dential Medal of Freedom in 1989.</p><p>Smith, Red orig. Walter Wellesley Smith (b. Sept. 25, 1905,  Green Bay, Wis., U.S.�d. Jan. 15, 1982, Stamford, Conn.) U.S. sports  columnist. Smith worked for various newspapers before his column,  �Views of Sport,� began appearing in the New York Herald Tribune in  1945; it was syndicated soon thereafter. He joined The New York Times  in 1971. His writing, mostly about major spectator sports, shunned jar�  gon and displayed literary craftsmanship, wry humour, and deep knowl�  edge. He won a Pulitzer Prize in 1976. His columns were collected in five  books, including Out of the Red (1950) and Strawberries in the Winter�  time (1974).</p><p>Smith, Samuel (b. July 27, 1752, Carlisle, Pa.�d. April 22, 1839,  Baltimore, Md., U.S.) U.S. politician. He was a merchant in Baltimore  and fought in the American Revolution. He served in the U.S. House of  Representatives (1793-1803, 1816-22) and Senate (1803-15, 1822-33).  As brigadier general of the Maryland militia, he commanded U.S. troops  that defended Baltimore from the British in the War of 1812. After lead�  ing the militia against rioters, he was elected mayor of Baltimore (1835�  38) at age 83.</p><p>Smith, Stevie orig. Florence Margaret Smith (b. Sept. 20, 1902,  Hull, Yorkshire, Eng.�d. March 7, 1971, London) British poet. She lived  most of her life with an aunt in a London suburb and worked many years  as a secretary. Her poetry, an unsentimental combination of the ludicrous  and the pathetic, expresses an original and visionary personality. In the  1960s her poetry readings became popular, and she made radio broad�  casts and recordings. Her Collected Poems (1975) is illustrated with her  James THURBER-like sketches; it includes her first book, A Good Time Was  Had by All (1937), and Not Waving but Drowning (1957), whose title  poem appears in many anthologies.</p><p>Smith, Theobald (b. July 31, 1859, Albany, N.Y., U.S.�d. Dec. 10,  1934, New York, N.Y., U.S.) U.S. microbiologist and pathologist. He  received his M.D. from Cornell University. He discovered that injected  heat-killed cultures of the causative microorganisms can immunize ani�  mals against disease. His discovery that Texas cattle fever is caused by a  parasite transmitted by ticks�the first definite proof of arthropods' role</p><p>in spreading disease�helped the scientific community accept mosqui�  toes� role in malaria and yellow fever. Smith was the first to differentiate  the bacteria that cause tuberculosis in cattle and in humans, and he was  one of the first to notice anaphylaxis. He also improved laboratory pro�  duction of VACCINES.</p><p>Smith, Vernon L. (b. Jan. 1, 1927, Wichita, Kan., U.S.) U.S. econo�  mist. Smith studied economics at the University of Kansas (M.A., 1952)  and at Harvard (Ph.D., 1955). He later taught at a number of institutions  and in 2001 became a professor at George Mason University. His exten�  sive laboratory experiments in economic analysis laid the foundation for  the field of experimental economics. Through such work he was able to  determine the theoretical equilibrium, or acceptable market price. He also  focused on the outcome of public auctions, showing that the way in which  the bidding was organized affected the selling price, and he devised  �wind-tunnel tests,� where trials of new alternative market designs, such  as those for a deregulated industry, could be tested. In 2002 he shared the  Nobel Prize for Economics with Daniel Kahneman.</p><p>Smith, W(illiam) Eugene (b. Dec. 20, 1918, Wichita, Kan., U.S.�d.  Oct. 15, 1978, Tucson, Ariz.) U.S. photojournalist. He worked as a pho�  tographer for local papers then went to New York City and worked for  several magazines. In 1943-44, as a war correspondent for Life maga�  zine, he covered many of the important battles of the Pacific theatre. He  produced a number of photoessays for Life, such as Spanish Village  (1951), a study of villagers� daily struggle to draw life from exhausted  soil. His most famous picture, The Walk to Paradise Garden (1947),  showing his own children entering a forest clearing, concluded the land�  mark photographic exhibition The Family of Man.</p><p>Smith, William (b. March 23, 1769, Churchill, Oxfordshire, Eng.�d.  Aug. 28, 1839, Northampton, Northamptonshire) English engineer and  geologist, known as the founder of the science of stratigraphy. The son of  a blacksmith, he was largely self-educated. He produced the first geologic  map of England and Wales (1815), setting the style for modem geologic  maps, and subsequently a series of geologic maps of the English coun�  ties. He introduced many techniques still used, including the use of fos�  sils for the dating of layers. Current geologic maps of England differ from  his primarily in detail, and many of the colourful names he applied to the  strata are also used today.</p><p>Smith &amp; Wesson U.S. gun manufacturer. The company has its roots  in an 1852 partnership between Horace Smith (1808-93) and Daniel B.  Wesson (1825-1906), who designed and marketed a lever-action, repeat�  ing magazine handgun that held a self-contained cartridge. Their venture  ran into financial difficulties and they were forced to sell it, but a second  partnership in 1856, manufacturing their new revolving-cylinder handgun  (now known as the .22 rimfire) proved more successful. The Civil War  made Smith &amp; Wesson a leading firearms manufacturer. In 1867 it began  selling in Europe. It supplied the British in World War I and the Allies in  World War II. In 1965 the Wesson family sold the company, which has  since changed hands several times.</p><p>Smith College Private liberal arts college for women in Northampton,  Mass. It was founded in 1871 through the bequest of Sophia Smith (1796-  1870). Bachelor�s degrees are granted in most major academic fields, and  master�s degrees are granted in biology, dance, education, music, religion,  social work, and theatre. Smith�s school of social work also grants doc�  toral degrees. The college belongs to a five-college cooperative with  Amherst, Hampshire, and Mount Holyoke colleges and the University of  Massachusetts at Amherst.</p><p>Smith Sound Channel between Ellesmere Island, Canada, and north�  western Greenland. About 3CM-5 mi (48-72 km) wide, the sound extends  northward for 55 mi (88 km) from Baffin Bay to the Kane Basin. It was  discovered by William Baffin in 1616 and named for Thomas Smythe  (Smith), who had promoted a number of voyages searching for a North�  west Passage.</p><p>smithing Fabrication and repair of metal objects by hot and cold forg�  ing on an anvil or with a power hammer or by welding and other means.  Blacksmiths traditionally worked with iron (anciently known as �black  metal�), making agricultural and other tools, fashioning hardware (e.g.,  hooks, hinges, handles) for the farm, the home, and industry, and shoe�  ing horses. The term smithing is also applied to work with precious met�  als (gold, silver) as well as other metals (e.g., tin, including tinplate, and  steel).</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1772 I Smithsonian Institution &#x25BA; Smyth</p><p>Smithsonian Institution U.S. research institution. Enabled by the  bequest of the English chemist James Smithson (1765-1829), it was estab�  lished in Washington, D.C., by an 1846 act of Congress. The Smithsonian  administers numerous bureaus, including the Freer Gallery of Art, the  John F. Kennedy Center for the Performing Arts, the National Air and  Space Museum, the National Gallery of Art, the National Museum of  History and Technology, the National Museum of Natural History, the  National Zoological Park, and the Smithsonian Astrophysical Observa�  tory.</p><p>smog Polluted air over a community. The term, a combination of  �smoke� and �fog,� was popularized in the early 20th century and now  commonly refers to the pall of automotive or industrial origin that lies  over many cities. Sulfurous smog results from the use of sulfur-bearing  fossil fuels, particularly coal, and is aggravated by dampness. Photo�  chemical smog requires neither smoke nor fog. Nitrogen oxides and  hydrocarbon vapours emitted from automobiles and other sources undergo  reactions in the presence of sunlight that produce a light brownish col�  oration of the atmosphere, reduced visibility, plant damage, irritation of  the eyes, and respiratory distress.</p><p>smoking Breathing the fumes of burning plant material, especially  tobacco, from a cigarette, cigar, or pipe. Despite social and medical argu�  ments against tobacco use, smoking is widely practiced around the world.  Nicotine is an alkaloid in tobacco that is addictive and can have both  stimulating and tranquilizing psychoactive effects. The tar (residue) and  gases produced by burning tobacco have many negative health effects.  They include lung cancer, pancreatic cancer, and laryngeal cancer; heart  disease and stroke; and emphysema and chronic bronchitis. Smoking also  increases other health-related risk factors (see asbestosis). A nonsmoker  who breathes secondhand smoke (such as the smoke from a lit cigarette)  is at an increased risk of the same diseases that affect smokers. Second�  hand smoke also increases the risk of sudden infant death syndrome. Doctor-  run programs, along with nicotine patches and gums that provide  diminishing doses of nicotine, are among the aids available to help those  who wish to quit smoking. Hypnosis, acupuncture, herbal remedies, and  other approaches are also widely advertised as ways to quit smoking.  Smoking has been greatly reduced in the health-conscious West even as  it rises in many less-developed countries.</p><p>Smoky Mountains See Great Smoky Mtns.</p><p>smoky quartz Common, coarse-grained variety of quartz that ranges  in colour from nearly black through smoky brown. No distinct boundary  exists between smoky and colourless quartz. Its abundance causes it to be  worth considerably less than either amethyst or citrine. Heating bleaches  the stone, the colour sometimes passing through yellow; these yellow  pieces are often sold as citrine.</p><p>Smolensk \smo-'lensk\ City (pop., 1999 est.: 355,700), western Rus�  sia. One of the oldest and most historic of Russian cities, it was a key  stronghold on the Dnieper River by the 9th century and became a commer�  cial centre on the trade route between the Baltic Sea and the Byzantine  Empire. Sacked by the Tatars c. 1240, it subsequently fell to Lithuania.  Sieges led to its capture by Moscow  in 1340 and recapture by Lithuania  in 1408. It was fought over several  times, then was finally taken by Rus�  sia in 1654. It was burned during  Napoleon�s invasion of Russia in  1812. The scene of heavy fighting in  World War II, it was occupied by the  Germans from 1941 to 1943. It is a  light-industry and educational cen�  tre.</p><p>Smollett Ysma-lotV, Tobias  (George) (baptized March 19,</p><p>1721, Cardross, Dumbartonshire,</p><p>Scot.�d. Sept. 17, 1771, near  Livorno, Tuscany) English satirical  novelist. Throughout his life Smol�  lett combined the roles of medical  man and writer. He is best known for  his novels, including the picaresque  novels Roderick Random (1748), a  graphic account of British naval life,</p><p>and Peregrine Pickle (1751), a comic, savage portrayal of 18th-century  society. In an active publishing career, he translated, wrote a Complete  History of England (1757-58), edited periodicals, including The Critical  Review, and compiled a 58-volume Universal History. In the mid-1760s,  seriously ill with tuberculosis, he retired to France. In 1766 he published  the irascible Travels Through France and Italy, his one nonfiction work  that is still read. His finest work, Humphry Clinker (1771), is a humor�  ous EPISTOLARY NOVEL.</p><p>Smoot-Hawley Tariff Act (1930) U.S. legislation that raised import  duties by as much as 50%, adding considerable strain to the worldwide  economic climate of the Great Depression. Despite a petition from 1,000  economists urging Pres. Herbert Hoover to veto the act, it was passed as  a protective measure for domestic industries. It contributed to the early  loss of confidence on Wall Street and signaled U.S. isolationism. Other  countries retaliated with similarly high protective tariffs, and overseas  banks began to collapse. In 1934 Pres. Franklin D. Roosevelt signed the  Trade Agreements Act, which reduced such tariffs.</p><p>Smrti Vsmri-te, 'smor-teV Class of Hindu sacred literature that is based  on human memory, as distinct from the Vedas, which are considered to  be divinely revealed. Smrti serves to elaborate, interpret, and codify Vedic  literature. It is considered less authoritative than Vedic literature but tends  to be more widely known. The term has come to refer particularly to texts  pertaining to law and social conduct, including the Kalpa-sutras, the  Puranas, the Bhagavadgita, the Ramayana, and the Mahabharata.</p><p>smuggling Act of importing and exporting secretly and illegally to  avoid paying duties or to evade enforcement of laws (e.g., drug- or  firearms-control laws). Smuggling is probably as old as the first tax or  regulation on trade. Two main methods exist: the undetected running of  cargoes across frontiers, and the concealment of goods in unlikely places  on ships or cars, in baggage or cargo, or on the person.</p><p>smut Disease of cereals, corn, grasses, onion, and sorghum, caused by  many species of fungi (see fungus). Spores accumulate in sootlike masses  (sori) that form within blisters in seeds, leaves, stems, flower parts, and  bulbs. The sori usually break up into a black powder that is readily dis�  persed by wind. Many smut fungi enter embryos or seedling plants,  develop throughout the plant, and appeal* externally only as the plants near  maturity. Other smuts are localized, infecting actively growing tissues.  Control includes growing resistant varieties in noninfested soil, treating  seeds with fungicide, using disease-free transplants, and destroying  infected plants or plant parts before the spores are released.</p><p>Smuts VsmuitsV Jan (Christian) (b. May 24, 1870, Bovenplaats, near  Riebeeck West, Cape Colony�d. Sept. 11, 1950, Irene, near Pretoria,  S.Af.) South African statesman, soldier, and prime minister (1919-24,  1939-48). An Afrikaner, Smuts studied law at Cambridge University.  Returning to South Africa, he was appointed state attorney in Pretoria by  Pres. Paul Kruger in 1897. He fought the British in the South African War  and joined with Louis Botha to oppose Alfred Milner�s implementation of  the peace terms. By 1905 Smuts was reconciled to British control and  sought to keep South Africa within the Commonwealth. In World War I  he joined again with Botha to suppress rebellion, conquer South West  Africa, and launch a campaign in East Africa. He attended the Versailles  peace conference and helped promote the League of Nations. When Botha  died, Smuts became prime minister. He was defeated in 1924 by a  National Party coalition. In 1933 he helped J.B.M. Hertzog force out the  extreme nationalists, and in 1939 he replaced Hertzog as prime minister.  Under his leadership South Africa helped prevent Germany and Italy from  conquering North Africa. In 1948 he was defeated by Daniel F. Malan�s  Nationalists. He ended his life as chancellor of Cambridge University.</p><p>Smyrna See izMiR</p><p>Smyth, Dame Ethel (Mary) (b. April 22, 1858, London, Eng.�d.  May 9, 1944, Woking, Surrey) British composer. Bom into a military  family, she studied at the Leipzig Conservatory and was encouraged by  Johannes Brahms and Antonin Dvorak. She first gained notice with her  sweeping Mass in D (1893). Her best-known work is The Wreckers  (1906), the most admired English opera of its time. Her March of the  Women (1911) reflected her strong involvement in the woman suffrage  movement. Her comic opera The Boatswain�s Mate (1916) enjoyed con�  siderable success. Her work is notably eclectic, ranging from conventional  to experimental. She wrote a multi volume autobiography.

He founded  the Toronto Maple Leafs in 1927 and made them into a leading hockey  club. In 1928 he coached the Canadian hockey team to an Olympic gold  medal. Since 1965 the Conn Smythe Trophy has been given annually to  the best player in the Stanley Cup play-offs.</p><p>snail Any species of gastropod that glides along on a broad tapered foot  and has a high coiled shell into which it can withdraw. Snails are found  in the ocean, in fresh waters, and on land. Most marine snails have gills  in the mantle cavity (see mollusk). Most land and freshwater snails have  no gills; they use the mantle cavity itself as a lung. Snails may be either  scavengers (of dead plant or animal matter) or predators. Some species  are used as food, and the shells of some are used as ornaments. See also  LIMPET, PERIWINKLE, SLUG, WHELK.</p><p>snail darter Rare species ( Percina tanasi) of darter that originally was  found only in the Little Tennessee River in the southeastern U.S. It became  the subject of a legal controversy in 1978, when its status as an endan�  gered species delayed for two years the construction of Tellico Dam. The  situation was resolved when the fish was successfully introduced into the  Hiwassee River.</p><p>snake Any member of about 19 reptile families (suborder Serpentes,  order Squamata) that has no limbs, voice, external ears, or eyelids, only  one functional lung, and a long, slender body. About 2,900 snake species  are known to exist, most living in the tropics. Their skin is covered with  scales. They have good eyesight, and they continually taste the surround�  ing air with their tongues. Though they lack any voice, they are capable  of hissing. Most live on the ground, but some are arboreal or aquatic, and  some are burrowers. They move by muscular contraction, aided by elon�  gated scales on their abdomen. They focus 70% of their mostly solitary  existence on tracking, capturing, and digesting their living prey. The con�  struction of their jaws and bodies enables them to swallow large prey  whole. Because they are ectotherms (cold-blooded), a single meal can  often sustain them for weeks. Mating and laying eggs or bearing live  young are brief seasonal activities. About one-tenth of snake species are  venomous; some can kill humans with their bite. Others kill their prey by  constriction or simply ingesting. Species range from less than 5 in. (12  cm) to over 30 ft (9 m) long. Snakes grow continuously throughout their  lives, shedding their outgrown skin at each growth increment. They are  found worldwide, but few species are found on islands or in regions with  long winters.</p><p>Internal and external features of a snake.</p><p>� MERRIAM-WEBSTER INC.</p><p>Snake River River, northwestern U.S. It is the largest tributary of the  Columbia River and one of the most important streams in the Pacific North�  west. It rises in the mountains of Yellowstone National Park in Wyoming  and flows south and west through Idaho, turning north at the Oregon bor�  der to enter the Columbia in southeastern Washington after a course of  1,040 mi (1,670 km). The lower Snake flows through Hells Canyon, the  deepest river gorge in North America. See photograph above.</p><p>snakebird See anhinga</p><p>snakebite Wound from the bite of a snake, especially a venomous one.  Nonvenomous snakes leave skin tears that may be treated like scratches.  A person bitten by a venomous snake needs medical care as soon as pos�</p><p>sible. Antivenin must be specific to  the type of venom, so the snake  should be identified or accurately  described. Different kinds of venom  break down red blood cells or attack  the nervous system, causing paralysis.  Local tissue destruction may lead to  gangrene. First aid for snakebite  seeks to keep the venom from  spreading to the rest of the body. The  bitten limb should be kept still below  heart level with a broad, firm (not  tight) bandage around it above the  bite. Exertion and excitement should  be avoided. Cutting, suction, tourni�  quets, and applying ice are not  advised.</p><p>snapdragon family Family  Scrophulariaceae, containing about  4,000 species of flowering plants in  190 genera, found worldwide. The  family is notable for its many orna�  mental garden plants, including  snapdragon ( Antirrhinum species)  and foxglove. Antirrhinum contains  about 40 species native to western North America and the western Medi�  terranean. Other members of the family, including butter-and-eggs, are  wildflowers. Flowers of the family are tubular and bilaterally symmetri�  cal (two-lipped).</p><p>snapper Any of about 250 species of valuable food fishes (family Lut-  janidae), found throughout the trop�  ics. These active schooling fishes  have slender bodies, large mouths,  sharp canine teeth, and blunt or  forked tails. Many species grow to  2-3 ft (60-90 cm) long. Snappers eat  crustaceans and other fishes. Some  species, such as the Atlantic dog  snapper, contain a toxin. The red  snapper, a bright red fish, inhabits  deep Atlantic waters. The emperor  snapper is a red-and-white Indo-  Pacific fish. The Atlantic yellowtail  snapper has a broad yellow stripe  from the nose to the wholly yellow  tail.</p><p>snapping turtle Either of two species (family Chelydridae) of edible,  omnivorous, freshwater turtles found  in North and Central America. They  are tan to black and have a rough  upper shell, a small cross-shaped  lower shell, a long tail, and a large  head with hooked jaws. Known for  their fierceness, they lunge at aggres�  sors and prey and bite them with  their powerful jaws. The common  snapping turtle ( Chelydra serpen�  tina) has a shell 8-12 in. (20-30 cm)  long and weighs 10-35 lbs (4.5-16  kg). The alligator snapping turtle  (Macroclemys temmincki), the larg�  est freshwater turtle in the U.S., has  a shell 16-28 in. (40-70 cm) long  and weighs 40-155 lbs (18-70 kg). It lies quietly on the bottom of slow  moving bodies of water, luring fishes by means of a wormlike append�  age on the floor of its open mouth.</p><p>Snead, Samfuel Jackson) (b.

Discovered in 1621 by Willebrord Snell (1580-1626), the law  went unpublished until its mention by Christiaan Huygens. If n x and n 2  represent the indices of refraction of two media, and 0 X and 0 2 are the  angles of incidence and refraction that a ray of light makes with the line  perpendicular to the boundary (the normal), Snell�s law states that n l /n 2  = sin 0 2 /sin 0j. Because the ratio nfn 2 is a constant for any given wave�  length of light, the ratio of the two sines is also a constant for any angle.</p><p>snipe Any of about 20 species of birds (family Scolopacidae) that fre�  quent wet meadows and marshes in  temperate and warm regions world�  wide. They are short-legged and  chunky, with brown, black, and  white stripes and bars. The wings are  pointed and angular. The long, flex�  ible bill is used to probe mud for  worms. The common snipe ( Gallin -  ago gallinago) is about 12 in. (30  cm) long, including the bill.</p><p>snook Any of about eight species  (genus Centropomus) of tropical  marine fishes that are long and sil�  very and have two dorsal fins, a long  head, and a large mouth with a pro�  jecting lower jaw. They are found  along the North and South American Atlantic and Pacific coasts, often in  estuaries and among mangroves and sometimes in fresh water. They range  from 1.5 to 5 ft (0.5-1.5 m) long and are valued for food and sport.</p><p>snooker Variation of English billiards. It is played with 15 red balls and  6 variously coloured balls. Snooker arose, probably in India, as a game  for soldiers in the 1870s. Players try to pocket first the red and then the  nonred balls, scoring one point for each red ball and the number value of  the others. �Snooker� refers to the position of the cue ball when it can�  not hit a required ball.</p><p>Snorri Sturluson Vsnor-e-'stUer-luB-soM (b. 1179, Iceland�d. Sept. 22,  1241, Reykjaholt) Icelandic poet, historian, and chieftain. Of an influen�  tial family, Snorri became the �lawspeaker,� or president, of the Icelan�  dic high court and a vassal of King Haakon IV of Norway. He was the  author of the Prose Edda and the Heimskringla, a history of Norwegian  kings. His writings are remarkable for their scope and formal assurance;  his genius lay in his power to present all that he perceived as a historian  with the immediacy of drama. His relations with Haakon deteriorated, and  he was assassinated on the king�s order.</p><p>snout beetle See weevil</p><p>snow Solid form of water that crystallizes in the atmosphere and falls to  the Earth, covering about 23% of the Earth�s surface either permanently or  temporarily. Snowflakes are formed  by crystals of ice that generally have  a hexagonal pattern. Snow cover has  a significant effect on climate and on  plant, animal, and human life. By  increasing the reflection of solar  radiation and interfering with the  conduction of heat from the ground,  it induces a cold climate. The low  heat conduction protects small plants  from the effects of the lowest winter  temperatures; on the other hand, late  disappearance of snow in the spring  delays the growth of plants.</p><p>Snow, C(harles) P(ercy) later  Baron Snow (of the City of  Leicester) (b. Oct. 15, 1905,</p><p>Leicester, Leicestershire, Eng.�d.</p><p>July 1, 1980, London) British novel�  ist, scientist, and government admin�</p><p>istrator. Snow was a molecular physicist at the University of Cambridge  for some 20 years and served as a scientific adviser to the British gov�  ernment. His 11-novel sequence Strangers and Brothers (1940-70), which  analyzes bureaucratic man and the corrupting influence of power, includes  The Masters (1951), The New Men (1954), and Corridors of Power  (1964). The Two Cultures and the Scientific Revolution (1959) and later  nonfiction works deal with the cultural separation between practitioners  of science and literature.</p><p>snow leopard or ounce Endangered species ( Uncia uncia) of noc�  turnal long-haired cat that inhabits the high mountains of Central Asia  and India. It is about 6 ft (1.8 m) long, including the 3-ft (1-m) tail, stands  about 2 ft (0.5 m) tall, and weighs 60-120 lb (27-55 kg). Its dense, soft  coat, consisting of an insulating undercoat and outer coat of 2-in. (5-cm)  hairs, is pale grayish with dark rosettes and a dark streak along the spine.  The whitish fur of the underparts may be 4 in. (10 cm) long. It preys on  marmots, wild sheep and goats, birds, and other animals. It is hunted  principally for the market in goods used in Asian traditional medicine.</p><p>snowberry Any of about 18 species of low shrubs that belong to the  genus Symphoricarpos of the honey�  suckle family. All are native to North  America, except for one species in  central China. All have bell-shaped,  pinkish or white flowers and snow-  white berries. The best-known orna�  mental species are S. albus, a shrub  3 ft (1 m) high, with delicate stems,  oval leaves, and large, pulpy, white  berries, and S. rivularis, slightly  larger, with elliptical leaves and a  profusion of berries. Creeping snow-  berry is a plant of the genus Gault-  heria (HEATH FAMILY).</p><p>snowboarding Sport of sliding  downhill over snow on a snowboard,  a wide ski ridden in a surfing posi�  tion. Derived from surfing and influenced also by skateboarding as well  as skiing, snowboarding began to burgeon among young people in the  U.S. in the mid-1980s. The first Olympic snowboarding competition was  held in the 1998 Winter Games. The two main events are giant slalom  (similar to Alpine giant slalom) and halfpipe, in which riders use a large,  snow-covered trench (halfpipe) to repeatedly launch themselves into the  air and perform various acrobatic feats.</p><p>Snowden (of Ickornshaw), Philip Snowden, Viscount (b.</p><p>July 18, 1864, Ickornshaw, Yorkshire, Eng.�d. May 15, 1937, Tilford,  Surrey) British politician. From 1893 he was a lecturer and writer for the  socialist Independent Labour Party (ILP), then became its leader (1903-  06). In the House of Commons (1906-18, 1922-31), he excelled in  debates on social and economic questions. He served as chancellor of the  Exchequer in James Ramsay MacDonald�s governments (1924, 1929-31)  and in 1931 secured Britain�s abandonment of the gold standard.</p><p>Snowdonia National Park Park, northern Wales. Established in  1951, it has an area of 838 sq mi (2,171 sq km). It is best known for its  mountains, composed largely of volcanic rock and cut by valleys that  show the influence of Ice Age glaciers. Mount Snowdon, 3,560 ft (1,085  m) high, is the highest peak in England and Wales.</p><p>snowdrop Any of about 12 spe�  cies and many variations of white-  flowered, spring-blooming, bulbous  Eurasian plants that make up the  genus Galanthus of the amaryllis fam�  ily. Several species, including com�  mon snowdrop (G. nivalis ) and giant  snowdrop (G. elwesii ), are cultivated  as ornamentals for their nodding,  sometimes fragrant flowers. They are  among the earliest garden flowers to  blossom in the spring. Similarly  named but very different, the snow�  drop tree, or silver bells (Halesia  Carolina, family Styracaceae), is a  tall tree with clustered, bell-shaped</p><p>Snowberry (Symphoricarpos rivularis)</p><p>SVEN SAMEUUS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>snowshoe hare &#x25BA; Social Democratic Party of Germany I 1775</p><p>flowers that grows in the southern U.S. The snowdrop bush ( Styrax offi�  cinalis) of eastern Europe and Asia Minor, also unrelated, grows to about  18 ft (6 m).</p><p>snowshoe hare or snowshoe rabbit or varying hare North�  ern North American species {Lepus americanus) of hare that undergoes  an annual colour change from brownish or grayish in summer to pure  white in winter.

Snyder worked as a  forest ranger, logger, and seaman and  studied Zen Buddhism in Japan  (1958-66). His poetry, early identi�  fied with the Beat movement, is rooted  in ancient, natural, and mythic expe�  rience. It initially contained images  drawn from his outdoor work in the  Pacific Northwest and later reflected  his interest in Eastern philosophies.</p><p>His volumes include Turtle Island (1974, Pulitzer Prize) and Mountains  and Rivers Without End (1996). From the late 1960s he has been an  important spokesman for communal living and ecological activism.</p><p>Soane, Sir John (b. Sept. 10, 1753, Goring, Oxfordshire, Eng.�d. Jan.  20, 1837, London) British architect. He was appointed architect to the  Bank of England in 1788. Various government appointments followed,  and in 1806 he succeeded his mentor, George Dance (1741-1837), as  professor of architecture at the Royal Academy. His work is characterized  by a tendency to reduce Classical elements to their structural essentials,  to use linear instead of modeled ornamentation, to favour shallow domes  and top lighting, and to handle interior spaces in an ingenious manner.</p><p>soap Any of a group of organic compounds that are salts of fatty acids,  usually stearic acid (with 18 carbon atoms) or palmitic acid (with 16 car�  bon atoms). The source may be any vegetable oil or animal fat. Soaps are  emulsifying agents commonly used for cleaning; they have long been  made from lye and fat. Detergents are entirely synthetic and may or may  not be soaps. Soaps of metals heavier than sodium are not very soluble;  the curdy precipitate made by soap in hard water is the calcium or mag�  nesium salt of the fatty acid in the soap. Heavy-metal soaps are used in  lubricating greases, as gel thickeners, and in paints. Napalm is an alumi�  num soap.</p><p>soap opera Broadcast serial drama, characterized by a permanent cast  of actors, a continuing story, tangled interpersonal situations, and a melo�  dramatic or sentimental style. Its name derived from the soap and deter�  gent manufacturers who originally often sponsored such programs on  radio. Soap operas began in the early 1930s as 15-minute radio episodes  and continued on television from the early 1950s as 30-minute and later  hour-long episodes. Usually broadcast during the day and aimed at house�  wives, they initially focused on middle-class family life, but by the 1970s  their content had expanded to include a wider variety of characters and  situations and a greater degree of sexual explicitness. In the 1980s simi�  lar series began to be aired in prime-time evening hours (e.g., Dallas and  Dynasty). See also Carlton E. Morse; Irna Phillips.</p><p>soaring or gliding Sport of flying a glider or sailplane. The craft is  towed behind a powered airplane to an altitude of about 2,000 ft (600 m)</p><p>and then released. The glider pilot makes use of rising currents of warm  air, such as those above a sunlit field, to maintain or gain altitude. Instru�  ments used include the altimeter, airspeed indicator, compass, and turn-  and-bank indicator. National soaring contests, which include events for  altitude, speed, distance, and accuracy in returning to a starting point, are  held annually.</p><p>Sobat Vso-,bat\ River River, east-central Africa. Formed by the con�  fluence of the Baro and Pibor rivers on the Ethiopian border, it merges  with the Jabal River in Sudan to form the White Nile. A major tributary of  the Nile River, it is 220 mi (354 km) long.</p><p>Sobukwe \s6-'biik-wa\, Robert (Mangaliso) (b. Dec. 5, 1924,  Graaff-Reinet, Cape Colony�d. Feb. 27, 1978, Kimberley, S.Af.) South  African black nationalist leader. Sobukwe insisted that South Africa be  returned to its indigenous inhabitants (�Africa for the Africans�). Charg�  ing the African National Congress with being contaminated by non-  African influences, he founded the Pan-Africanist Congress in 1959 and  became a leader in the Pan-African movement. Arrested in 1960, he spent  the rest of his life in prison or under house arrest.</p><p>soccer See football  social class See social class</p><p>social contract Actual or hypothetical compact between the ruled and  their rulers. The original inspiration for the notion may derive from the  biblical covenant between God and Abraham, but it is most closely asso�  ciated with the writings of Thomas Hobbes, John Locke, and Jean-Jacques  Rousseau. Hobbes argued that the absolute power of the sovereign is jus�  tified by a hypothetical social contract in which the people agree to obey  him in all matters in return for a guarantee of peace and security, which  they lack in the warlike �state of nature� posited to exist before the con�  tract is made. Locke believed that rulers also were obliged to protect pri�  vate property and the right to freedom of thought, speech, and worship.  Rousseau held that in the state of nature people are unwarlike but also  undeveloped in reasoning and morality; in surrendering their individual  freedom, they acquire political liberty and civil rights within a system of  laws based on the �general will� of the governed. The idea of the social  contract influenced the shapers of the American Revolution and the French  Revolution and the constitutions that followed them.</p><p>Social Credit Party Canadian political party. Founded in 1935 by  William Aberhart, it was based on the social-credit theory of the British  economist Clifford Douglas (1879-1952). By the late 1930s the party  advocated employee profit sharing and shareholding. It led the provincial  governments in Alberta (1935-71) and British Columbia (1952-71, 1976�  1991), and it won several seats in the parliament in Ottawa between 1935  and 1980. The party suffered from internal conflicts, and at the end of the  20th century it had failed to win seats in any provincial assembly.</p><p>social Darwinism Theory that persons, groups, and �races� are sub�  ject to the same laws of natural selection as Charles Darwin had proposed  for plants and animals in nature. Social Darwinists, such as Herbert Spen�  cer and Walter Bagehot in England and William Graham Sumner in the  U.S., held that the life of humans in society was a struggle for existence  ruled by �survival of the fittest,� in Spencer�s words. Wealth was said to  be a sign of natural superiority, its absence a sign of unfitness. The theory  was used from the late 19th century to support laissez-faire capitalism and  political conservatism. Social Darwinism declined as scientific knowledge  expanded.</p><p>social democracy Political ideology that advocates a peaceful, evo�  lutionary transition of society from capitalism to socialism, using established  political processes. It rejects Marxism�s advocacy of social revolution.  Social democracy began as a political movement in Germany in the 1870s.  Eduard Bernstein argued (1899) that capitalism was overcoming many of  the weaknesses Karl Marx had seen in it (including unemployment and  overproduction) and that universal suffrage would lead peacefully to a  socialist government. After 1945, social-democratic governments came to  power in West Germany (see Social Democratic Party), Sweden, and Brit�  ain (under the Labour Party). Social-democratic thought gradually came to  regard state regulation (without state ownership) as sufficient to ensure  economic growth and a fair distribution of income.</p><p>Social Democratic Party of Germany (SPD) German political  party.

The SPD�s right wing under Friedrich Ebert  helped crush the Soviet-style uprisings in Germany in 1918, and the party  won 37% of the vote in the 1919 elections. The government�s acceptance  of the Treaty of Versailles and Germany�s severe economic problems  caused a drop in support in the 1920s. Outlawed by the Nazis in 1933,  the party revived after World War II in West Germany and grew steadily,  receiving almost 46% of the vote in the 1972 elections. It formed coali�  tion governments with the Christian Democratic Union (1966-69) and the  Free Democratic Party (1969-82). In 1990 it reunited with a newly inde�  pendent SPD from the former East Germany. The party returned to power  in 1998 under Gerhard Schroder, who served as chancellor of Germany  until 2005.</p><p>Social Gospel Religious social-reform movement in the U.S., promi�  nent from c. 1870 to 1920 among liberal Protestant groups. The move�  ment focused on applying moral principles to the improvement of  industrialized society and particularly to reforms such as the abolition of  child labour, a shorter workweek, and factory regulation. Many of its aims  were realized through the rise of organized labour and through legislation  of the New Deal.</p><p>social history Branch of history that emphasizes social structures and  the interaction of different groups in society rather than affairs of state.  An outgrowth of economic history, it expanded as a discipline in the  1960s. It initially focused on disenfranchised social groups but later began  to focus more attention on the middle and upper classes. As a field, it  often borders on economic history on the one hand and on sociology and  ethnology on the other.</p><p>social insurance Compulsory public-insurance program that protects  against various economic risks (e.g., loss of income due to sickness, old  age, or unemployment). Social insurance is considered one type of social  security, though the two terms are sometimes used interchangeably. The  first compulsory national social-insurance programs were established in  Germany under Otto von Bismarck: health insurance in 1883, workers'  compensation in 1884, and old-age and disability pensions in 1889. Aus�  tria and Hungary soon followed Germany�s example. After 1920, social  insurance was rapidly adopted throughout Europe and the Western Hemi�  sphere. The U.S. lagged behind until the passage of the Social Security Act  in 1935. Social Security in the U.S. now provides retirement benefits,  health care for persons over a specific minimum age, and disability insur�  ance. Social-insurance contributions are normally compulsory and may  be made by the insured person�s employer and the state as well as by the  individual. Social insurance is usually self-financing, with contributions  being placed in specific funds for that purpose. See also unemployment  insurance; welfare.</p><p>social learning In psychological theory, a change in behaviour that is  controlled by environmental influences rather than by innate or internal  forces. In zoology, social learning is exhibited by innumerable species of  birds and mammals, who modify their behaviour by observing and imi�  tating the adults around them. Birdsong is a socially learned behaviour.</p><p>social psychology Branch of psychology concerned with the person�  ality, attitudes, motivations, and behaviour of the individual or group in the  context of social interaction. The field emerged in the U.S. in the 1920s.  Topics include the attribution of social status based on perceptual cues,  the influence of social factors (such as peers) on a person�s attitudes and  beliefs, the functioning of small groups and large organizations, and the  dynamics of face-to-face interactions.</p><p>Social Realism Trend in U.S. art, originating c. 1930, toward treating  themes of social protest�poverty, political corruption, labour-  management conflict�in a naturalistic manner. The movement was  stimulated in part by the Ash Can school, the Great Depression, and the  New Deal�s arts patronage programs, including the WPA Federal Art  Project. Works in this vein include Ben Shahn�s Passion of Sacco and  Vanzetti (1931-32) and William Gropper�s The Senate (1935).</p><p>social science Any discipline or branch of science that deals with the  sociocultural aspects of human behaviour. The social sciences generally  include cultural anthropology, economics, political science, sociology, crimi�  nology, and social psychology. Comparative law and comparative religion  (the comparative study of the legal systems and religions of different  nations and cultures) are also sometimes regarded as social sciences.</p><p>social security Public provision for the economic security and social  welfare of all individuals and their families, especially in the case of  income losses due to unemployment, work injury, maternity, sickness, old  age, and death. The term encompasses not only social insurance but also  health and welfare services and various income maintenance programs  designed to improve the recipient�s welfare through public services. Some  of the first organized cooperative efforts to provide for the economic  security of individuals were instituted by workingmen�s associations,  mutual-benefit societies, and labour unions; social security was not widely  established by law until the 19th and 20th centuries, with the first mod�  ern program appearing in Germany in 1883. Almost all developed nations  now have social security programs that provide benefits or services  through several major approaches such as social insurance and social  assistance, a needs-based program that pays benefits only to the poor. See  also Social Security Act; unemployment insurance; welfare; workers' compen�  sation.</p><p>Social Security Act (Aug. 14, 1935) Legislation that established a  national old-age pension system in the U.S. Dissatisfied with the govern�  ment response to the Great Depression, about five million people joined  �Townsend clubs� to support the plan of Francis E. Townsend (1867�  1960) to demand a $200 monthly pension for everyone over the age of  60. Pres. Franklin D. Roosevelt established a committee on economic secu�  rity (1934), which recommended legislative action to the U.S. Congress.  The act provided old-age benefits to be financed by a payroll tax on  employers and employees. The system was later expanded to include  dependents, the disabled, and others.</p><p>social settlement See settlement house</p><p>social status Relative rank that an individual holds, with attendant  rights, duties, and lifestyle, in a social hierarchy based on honour and  prestige. Status is often ascribed on the basis of sex, age, family relation�  ships, and birth, placing one into a particular social group irrespective of  ability or accomplishments. Achieved status, on the other hand, is based  on educational attainment, occupational choice, marital status, and other  factors involving personal effort. Status groups differ from social CLASSes  in being based on considerations of honour and prestige rather than purely  economic position. Relative status is a major determinant of people�s  behaviour toward one another, and competition for status seems to be a  prime human motivator.</p><p>Social War or Italic War or Marsic War (90-89 bc) Rebellion  waged by ancient Rome�s Italian allies (Latin, socii). The allies in cen�  tral and southern Italy had aided Rome in its wars, but they were denied  the privileges of Roman citizenship. The people of central Italy�s hills�  the Marsi in the north and the Samnites in the south�organized a con�  federacy and began an uprising for independence, winning victories over  Roman armies in the north and south. After Rome granted citizenship to  those who had not revolted and those who would immediately lay down  their arms, Italian interest in the struggle declined. Sulla defeated the  weakened rebels in the south, and legislation was passed to unify Italy  south of the Po River.</p><p>social welfare See welfare</p><p>social work Any of various professional activities or methods con�  cerned with providing social services (such as investigatory and treatment  services or material aid) to disadvantaged, distressed, or vulnerable per�  sons or groups. The field originated in the charity organizations in Europe  and the U.S. in the late 19th century. The training of volunteer workers  by these organizations led directly to the founding of the first schools of  social work and indirectly to increased government responsibility for the  welfare of the disadvantaged. Social workers may serve the needs of chil�  dren and families, the poor or homeless, immigrants, veterans, the men�  tally ill, the handicapped, victims of rape or domestic violence, and  persons dependent on alcohol or drugs. See also welfare.</p><p>socialism System of social organization in which private property and  the distribution of income are subject to social control; also, the political  movements aimed at putting that system into practice. Because �social  control� may be interpreted in widely diverging ways, socialism ranges  from statist to libertarian, from Marxist to liberal. The term was first used  to describe the doctrines of Charles Fourier, Henri de Saint-Simon, and Rob�  ert Owen, who emphasized noncoercive communities of people working  noncompetitively for the spiritual and physical well-being of all (see uto�  pian sociausm). Karl Marx and Friedrich Engels, seeing socialism as a tran-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Socialist International &#x25BA; Socrates I 1777</p><p>sition state between capitalism and communism, appropriated what they  found useful in socialist movements to develop their �scientific social�  ism.� In the 20th century, the Soviet Union was the principal model of  strictly centralized socialism, while Sweden and Denmark were well-  known for their noncommunist socialism. See also collectivism, communi-  TARIANISM, SOCIAL DEMOCRACY.</p><p>Socialist International See Second International</p><p>Socialist Realism Officially sanctioned theory and method of artistic  and literary composition in the Soviet Union from 1932 to the mid-1980s.  Following the tradition of 19th-century Russian realism, Socialist Realism  purported to serve as an objective mirror of life. Instead of critiquing  society, however, it took as its primary theme the struggle to build social�  ism and a classless society and called for the didactic use of art to develop  social consciousness. Artists were expected to take a positive view of  socialist society and to keep in mind its historical relevance, requisites  that seldom coincided with their real experiences and frequently under�  mined the artistic credibility of their works.</p><p>Socialist Revolutionary Party (SR) Russian political party. The  ideological heir to the 19th-century Narodniks (Populists), it was founded  in 1901 by agrarian socialists and appealed mainly to the peasantry. It  was the principal alternative to the Russian Social-Democratic Workers'  Party in the early 20th century. It relied on terrorist tactics and carried out  hundreds of political assassinations. By 1917 it was Russia�s largest  socialist group; its members included Aleksandr Kerensky, Viktor Chernov,  and Catherine Breshkovsky. The party split after the Russian Revolution of  1917, and its radical wing joined the Bolshevik government. It was sup�  pressed by Vladimir Lenin after the Russian Civil War.</p><p>Societe Generate \s6s-ye-'ta-zha-na-'ral\ Major French commercial  bank, with headquarters in Paris. It was established in 1864 to offer bank�  ing and investment services, and was nationalized in 1946 along with  several other large French banks.

Its chief island is Tahiti. The Society Islands comprise two  groups, the Windward Islands and the Leeward Islands. They are volca�  nic in origin and mountainous. Claimed for Britain in 1767, the islands  were visited in 1769 by Capt. James Cook with a scientific expedition of  the Royal Society (hence their name). They were claimed by France in  1768 and became a French protectorate in 1842, a French colony in 1881,  and a part of French Oceania in 1903. Their chief products are copra and  pearls.</p><p>sociobiology Systematic study of the biological basis of social behav�  iour. The concept was popularized by Edward O. Wilson in his Sociobi�  ology (1975) and by Richard Dawkins (b. 1941) in The Selfish Gene  (1976). Sociobiology attempts to understand and explain animal (and  human) social behaviour in the light of natural selection and other bio�  logical processes. A central tenet is that the transmission of genes through  successful reproduction is the central motivator in animals� struggle for  survival, and that animals will behave in ways that maximize their chances  of transmitting their genes to succeeding generations. Though sociobiol�  ogy has contributed insights into animal behaviour (such as altruism in  social insects and male-female differences in certain species), it remains  controversial when applied to human social behaviour. See also ethology.</p><p>sociocultural evolution Development of culture and society from  simple to complex forms. Europeans had sought to explain the existence  of various �primitive� societies, some believing that such societies rep�  resented the lost tribes of Israel, others speculating that primitive peoples  had degenerated since the time of Adam from an originally �barbarous�  to an even lowlier �savage� state. European society was taken to epito�  mize the highest state of existence, �civilization.� In the late 19th century,  Edward Burnett Tylor and Lewis Henry Morgan elaborated the theory of  unilinear evolution, specifying criteria for categorizing cultures accord�  ing to their standing within a fixed system of growth of humanity as a  whole and examining the modes and mechanisms of this growth. A wide�  spread reaction followed; Franz Boas introduced the �culture history�  approach, which concentrated on fieldwork among native peoples to iden�  tify actual cultural and historical processes rather than speculative stages  of growth. Leslie White, Julian Steward, and others sought to revive</p><p>aspects of sociocultural evolutionism, positing a progression ranging from  bands and tribes at one end to chiefdoms and states at the other. More  recently some anthropologists have adopted a general systems approach,  examining cultures as emergent systems. Others continue to reject evo�  lutionary thinking and look instead at historical contingencies, contacts  with other cultures, and the operation of cultural symbol systems. See also  social Darwinism.</p><p>sociolinguistics Study of the sociological aspects of language. Socio-  linguists attempt to isolate the linguistic features used in particular situ�  ations that mark the various social relationships among the participants  and the significant elements of the situation. Factors influencing the choice  of sounds, grammatical elements, and vocabulary may include age, gen�  der, education, ethnic identity, occupation, and peer-group identification.  See also interactionism, linguistics, pragmatics, semiotics.</p><p>sociology Science of society, social institutions, and social relation�  ships, and specifically the systematic study of the development, structure,  interaction, and collective behaviour of organized human groups. It  emerged at the end of the 19th century through the work of Emile Durkheim  in France, Max Weber and Georg Simmel in Germany, and Robert E. Park  and Albion Small in the U.S. Sociologists use observational techniques,  surveys and interviews, statistical analysis, controlled experiments, and  other methods to study subjects such as the family, ethnic relations, school�  ing, social status and class, bureaucracy, religious movements, deviance,  the elderly, and social change.</p><p>sockeye salmon or red salmon Food fish (Oncorhynchus nerka)  of the North Pacific that constitutes  almost 20% of the commercial fish�  ery of Pacific Salmon.

The island,  mentioned in various legends, was long ruled by the Mahra sultans of  southeastern Yemen, except for a brief Portuguese occupation (1507-11).  In 1886 it came under British control and in 1967 became part of inde�  pendent Yemen. Its chief town is Hadlboh.</p><p>Socrates (b. c. 470, Athens�d. 399 bc, Athens) Greek philosopher  whose way of life, character, and thought exerted a profound influence on  ancient and modern philosophy. Because he wrote nothing, information  about his personality and doctrine is derived chiefly from depictions of his  conversations and other information in the dialogues of Plato, in the  Memorabilia of Xenophon, and in various writings of Aristotle. He fought  bravely in the Peloponnesian War and later served in the Athenian boule  (assembly). Socrates considered it his religious duty to call his fellow citi�  zens to the examined life by engaging them in philosophical conversation.  His contribution to these exchanges typically consisted of a series of prob�  ing questions that cumulatively revealed his interlocutor�s complete igno�  rance of the subject under discussion; such cross-examination used as a  pedagogical technique has been called the �Socratic method.� Though  Socrates characteristically professed his own ignorance regarding many of  the (mainly ethical) subjects he investigated (e.g., the nature of piety), he  did hold certain convictions with confidence, including that: (I) human  wisdom begins with the recognition of one�s own ignorance; (2) the unex�  amined life is not worth living; (3) ethical virtue is the only thing that mat�  ters; and (4) a good person can never be harmed, because whatever  misfortune he may suffer, his virtue will remain intact. His students and  admirers included, in addition to Plato, Alcibiades, who betrayed Athens in  the Peloponnesian War, and Critias (c. 480-403 bc), who was one of the  Thirty Tyrants imposed on Athens after its defeat by Sparta. Because he was  connected with these two men, but also because his habit of exposing the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1778 I soda &#x25BA; software</p><p>ignorance of his fellow citizens had made him widely hated and feared,  Socrates was tried on charges of impiety and corrupting the youth and con�  demned to death by poisoning (the poison probably being hemlock) in 399  bc; he submitted to the sentence willingly. Plato�s Apology purports to be  the speech that Socrates gave in his own defense. As depicted in the Apol�  ogy, Socrates� trial and death raise vital questions about the nature of  democracy, the value of free speech, and the potential conflict between  moral and religious obligation and the laws of the state.</p><p>soda, caustic See caustic soda</p><p>Soddy, Frederick (b. Sept. 2, 1877, Eastbourne, Sussex, Eng.�d.  Sept. 22, 1956, Brighton, Sussex) British chemist. He worked with Ernest  Rutherford to develop a theory of the disintegration of radioactive ele�  ments. In 1912 he was among the first to conclude that elements might  exist in forms (isotopes) of different atomic weights but indistinguishable  chemically. In Science and Life (1920) he pointed out the value of iso�  topes in determining geologic age (see carbon-14 dating). For his inves�  tigations of radioactivity and isotopes, he received a 1921 Nobel Prize.</p><p>sodium Chemical element, one of the alkali metals, chemical symbol Na,  atomic number 11. A very soft, silvery white metal, the sixth most abun�  dant element on Earth, it occurs mainly as haute, never free. Extremely  reactive, it is used as a chemical reagent and raw material, in metallurgy,  as a heat exchanger (in nuclear power generators and certain types of  engines), and in sodium-vapour lamps (see electric discharge lamp). Sodium  is essential for life but rarely deficient in diets; high intake is linked to  hypertension. Sodium in compounds, many of great industrial importance  (including bicarbonate of soda, caustic soda, sodium nitrate [Chile saltpe�  tre], and sodium chloride), has valence 1 . Sodium carbonate, one of the four  most important basic chemical commodities, is used in making glass,  detergents, and cleansers. Sodium hypochlorite, familial' as household  bleach, is also used to bleach paper pulp and textiles, to chlorinate water,  and in some medicines. The sulfate is used in the kraft process and also  used to make paperboard, glass, and detergents.

According to the Old Testament book of Genesis, the  notorious cities were destroyed by �brimstone and fire� because of their  wickedness. The site of the cities is unknown but may have beeen in an  area now beneath the waters of the Dead Sea. Archaeological evidence  shows that the area may once have been fertile and could have drawn the  biblical Lot to graze his flock. The cities� legendary wickedness has  inspired many writers, including Jean Giraudoux and Nikos Kazantzakis.</p><p>sodomy Noncoital carnal copulation. Sodomy is a crime in some juris�  dictions. Some sodomy laws, particularly in Middle Eastern countries and  those jurisdictions observing Shariah law, provide penalties as severe as  life imprisonment for homosexual intercourse, even if the relations are  between legally consenting adults. Other sodomy laws proscribe a vari�  ety of other forms of sexual contact and apply even to married couples.  No such regulations are found in the law codes of Denmark, France, Italy,  Sweden, The Netherlands, or Switzerland, among other countries.The  Wolfenden committee in Britain and the American Law Institute recom�  mended abolition of criminal penalties for sodomy, except in cases involv�  ing violence, children, or public solicitation. This position was adopted  in England in 1967 and has been adopted in many U.S. states as well.</p><p>sofer or sopher \so-'fer, 'so-forV In Judaism, a scholar-teacher of the 5th-  2nd centuries bc who transcribed, edited, and interpreted the Bible. The first  sofer was Ezra, who, with his disciples, initiated a tradition of rabbinical  scholarship that is still central in Judaism. This tradition of scholarship  arose to meet the specific need of applying the idealistic aspirations of the</p><p>Torah and oral tradition to everyday life, thus in effect codifying Mosaic  law. The soferim were important historically for having fixed the canon of  the Hebrew scriptures. Later the term sofer came to refer to one who taught  the Bible to children or who was qualified to write Torah scrolls.</p><p>Sofia Vso-fe-s, so-'fe-3,\ ancient Serdica City (pop., 2001: 1,096,389),  capital of Bulgaria. Established as a Thracian settlement c. 8th century bc,  it flourished under the Romans. Plundered by the Huns in the 5th century  ad, it was rebuilt under the Byzantine Empire. In 809 it became a Bul�  garian town but reverted to Byzantine rule from 1018 to 1185, when the  second Bulgarian empire was established. The Turks held it from 1382  until it was liberated by the Russians in 1878. In 1879 it was made the  Bulgarian capital. It is the country�s principal transportation and cultural  centre and the site of many industries. Among its educational institutions  is the University of Sofia (1888), Bulgaria�s oldest university. Its histori�  cal monuments include the 6th-century church of St. Sofia.</p><p>soft coal See bituminous coal</p><p>soft drink Nonalcoholic beverage, usually carbonated, consisting of  water (soda water), flavouring, and a sweet syrup or artificial sweetener.  Attempts to reproduce the natural effervescence of certain spring waters  for presumed health benefits began before 1700. Joseph Priestley�s experi�  ments with �fixed air� (carbon dioxide) led in the late 1790s to the suc�  cessful preparation of carbonated �mineral water� by Jacob Schweppe of  Geneva; by the early 1800s it was being bottled and sold commercially.  Today there are hundreds of varieties of flavoured soft drinks. Some of  the world�s largest corporations (including Coca-Cola Co. and PepsiCo)  founded their businesses on soft-drink manufacturing.</p><p>soft money In the U.S., paper money as contrasted with coins, or hard  money; also, unregulated monetary donations to political parties or can�  didates. In the 19th and early 20th centuries, advocates of soft money  favoured governmental deficit spending to stimulate consumption and  employment. Fiscal conservatives, who put their trust in hard money,  maintained that government should not spend beyond its resources. In the  late 20th century, strict regulations governed the source, amount, and use  of donations to particular candidates (hard money), but few such laws  applied to contributions for the general promotion of a political party�s  message (soft money). In 2002 the U.S. Congress passed legislation that  prohibited soft money contributions to the national political parties and  strictly limited such contributions to state and local parties.</p><p>softball Game resembling baseball but played on a smaller diamond with  a larger ball (12 in.

Soga Umako (d.  626) overcame the powerful Mononobe and Nakatomi clans, who sup�  ported the native Shinto religion over Buddhism, and contrived to have  his niece proclaimed empress, selecting one of his nephews to be her  regent (see Shotoku). The next generation alienated other aristocratic  families with their high-handed ways, and after many intrigues and assas�  sinations Soga power was crushed in 645 by Prince Nakano Oe, who was  to become the emperor Tenji, aided by Fujiwara Kamatari, founder of the  Fujiwara family.

Soil serves as a natural reservoir of  water and nutrients, as a medium for the filtration and breakdown of inju�  rious wastes, and as a participant in the cycling of carbon and other ele�  ments through the global ecosystem. It has evolved through the weathering  of solid materials such as consolidated rocks, sediments, glacial tills, vol�  canic ash, and organic matter. The bulk of soil consists of mineral par�  ticles composed of silicate ions combined with various metal ions.  Organic soil content consists of undecomposed or partially decomposed  biomass as well as humus, an array of organic compounds derived from  broken down biomass.</p><p>soil mechanics Study of soils and their utilization, especially in plan�  ning foundations for structures and highways. How the soil of a given site  will support the weight of structures or respond to movement in the course  of construction depends on a number of properties (e.g., compressibility,  elasticity, and permeability). Examination techniques include trench�  digging, boring, and pumping samples to the surface with water. Seismic  testing and measurement of electrical resistance also yield helpful infor�  mation. In road construction, soil mechanics helps determine which type  of pavement (rigid or flexible) will last longer. The study of soil charac�  teristics is also used to choose the most suitable method for excavating  underground tunnels. See also foundation, settling.</p><p>soil science Scientific discipline that investigates soils as primary natu�  ral resources at the surface of the Earth.

The most successful of Japan�s new religious movements of the 20th cen�  tury, it draws on the 13th-century teachings of Nichiren. Like other move�  ments in Nichiren Buddhism, it takes the Lotus Sutra as its chief scripture.  Founded in 1930, Soka-gakkai came to prominence in the later 20th cen�  tury, eventually developing a membership of over 6 million. In 1964 it  established the Komeito (Clean Government Party), which by the 1980s  was Japan�s third-largest political party.

In the early 1930s she also formed her  own dance group, the Dance Unit. From 1939 to 1949 she spent part of  each year as a teacher and choreographer in Mexico City, where she  formed Mexico�s first modem-dance group. Throughout her career and  into the 1990s, she continued to form various companies and for them she  often choreographed works on subjects of social concern.</p><p>Sokoto \so-'ko-to\ City (pop., 1996 est.: 204,900), northwestern Nige�  ria. It lies along the Sokoto River on a traditional caravan route that leads  north across the Sahara. It was the capital of the Fulani empire. Modem  Sokoto is a major trade centre for agriculture and leather crafts. A pil�  grimage centre, it is the site of mosques, a sultan�s palace, and Usman dan  Fodio�s tomb and other holy shrines. Usman dan Fodio University was  founded in 1975.</p><p>Sol Vsal\ In Roman religion, the name of two distinct sun gods at Rome.  The original Sol, or Sol Indiges, had an annual sacrifice and shrines on  the Quirinal and in the Circus Maximus. After the importation of various  Syrian sun cults, Elagabalus built a temple to Sol Invictus on the Palatine  and attempted to make his worship the principal religion at Rome. Aure-  lian later reestablished the worship and erected a temple to Sol in the  Campus Agrippae. The worship of Sol remained the chief imperial cult  until the rise of Christianity.</p><p>solar cell Any device that directly converts the energy in light into elec�  trical energy through the process of photovoltaics (see photovoltaic effect).  Solar cells do not use chemical reactions to produce electric power, and  they have no moving parts. Most solar cells are designed for converting  sunlight into electricity. In large arrays, which may contain many thousands  of individual cells, they can function as central electric power stations  analogous to nuclear, coal-, or oil-fired power plants. Much smaller assem�  blies of solar cells are used to provide electric power in remote locations  including space satellites; because they have no moving parts that could  require service or fuels that would require replenishment, solar cells are  ideal for providing power in space. See illustration on following page.</p><p>solar cycle Period in which several important kinds of solar activity  repeat, discovered in 1843 by Samuel Heinrich Schwabe (1789-1875).  Lasting about 22 years on average, it includes two 11 -year cycles of sun�  spots, whose magnetic polarities alternate between the Sun�s northern and  southern hemispheres, and two peaks and two declines in the phenomena  (e.g., solar prominences, auroras) that vary in the same period. Attempts  have been made to connect the solar cycle to various other phenomena,  including possible slight variations in the diameter of the Sun, sequences  of annual growth rings in trees, and even the stock market�s rise and fall.</p><p>solar energy Radiation from the Sun that can produce heat, generate  electricity, or cause chemical reactions. Solar collectors collect solar  radiation and transfer it as heat to a carrier fluid. It can then be used for  heating. Solar cells convert solar radiation directly into electricity by  means of the photovoltaic effect. Solar energy is inexhaustible and non�  polluting, but converting solar radiation to electricity is not yet commer�  cially competitive, because of the high cost of producing large-scale solar  cell arrays and the inherent inefficiency in converting light to electricity.</p><p>solar flare Sudden intense brightening of a small part of the Sun�s sur�  face, often near a sunspot group. Flares develop in a few minutes and may  last several hours, releasing intense X rays and streams of energetic par�  ticles. They appear to be connected with changes in the Sun�s magnetic  fields during the solar cycle. The ejected particles take a day or two to  reach the vicinity of Earth, where they can disrupt radio communications  and cause auroras, and may pose a radiation hazard to astronauts.</p><p>solar heating Use of solar radiation to heat water or air in buildings.  There are two types: passive and active.

A well-insulated building with a large south-facing window, for  instance, can trap heat on sunny days and reduce reliance on gas, oil, or  electricity. Brick, stone, or tile capacity walls are often incorporated to  absorb the sun�s energy and radiate it into the interior, usually after a time  lag of several hours. In active solar heating, mechanical means are used  to collect, store, and distribute solar energy. In liquid-based systems, a  blackened metal plate on the exterior absorbs sunlight and traps heat,  which is transferred to a carrier fluid. Alternatively, fluid may be pumped  through a glass tube or volume of space onto which sunlight has been  focused by mirrors. After picking up heat from the collector, the warm  fluid is pumped to an insulated storage tank. The system can supply a  home with hot water from the tank or provide space heating with the  warmed water flowing through tubes in floors and ceilings.</p><p>solar nebula Gaseous cloud from which, in the nebular hypothesis of  the origin of the solar system, the Sun and planets formed by condensa�  tion. In 1755 Immanuel Kant suggested that a nebula gradually pulled  together by its own gravity developed into the Sun and planets. Pierre-  Simon, marquis de Laplace, in 1796 proposed a similar model, in which a  rotating and contracting cloud of gas�the young Sun�shed concentric  rings of matter that condensed into the planets. But James Clerk Maxwell  showed that, if all the matter in the known planets had once been distrib�  uted this way, shearing forces would have prevented such condensation.  Another objection was that the Sun has less anguar momentum than the  theory seems to require. In the early 20th century most astronomers pre�  ferred the collision theory: that the planets formed as a result of a close  approach to the Sun by another star. Eventually, however, stronger objec�  tions were mounted to the collision theory than to the nebular hypothesis,  and a modified version of the latter�in which a rotating disk of matter  gave rise to the planets through successively larger agglomerations, from  dust grains through panetesimals and protoplanets�became the prevailing  theory of the solar system�s origin.</p><p>solar neutrino problem See neutrino problem, soar</p><p>solar prominence Arched stream of hot gas projecting from the Sun�s  surface into the chromosphere or corona.

Another component of  the solar system is the soar wind. The Sun contains more than 99% of  the mass of the solar system; most of the rest is distributed among the  nine planets, with Jupiter containing about 70%. According to the prevail�  ing theory, the solar system originated from the soar nebua.

June 21, 1919, Turin, Italy) Italian-born  U.S. architect. After receiving a doctorate from Turin Polytechnic, he  worked under Frank Lloyd Wright in Arizona (1947-49). In 1959 he began  to draw up plans for a series of compact urban centres that would extend  vertically into space rather than horizontally along the ground. These  megastructures were designed to conserve energy and resources (partly  through reliance on solar energy and elimination of automobile use within  the city), preserve natural surroundings, and condense human activities  within integrated total environments. Soleri coined the term arcology  (from �architecture� and �ecology�) to describe his utopian constructions,  which he delineated in drawings of great beauty and imagination. In 1970  he began constructing a prototype town called Arcosanti, for a population  of 5,000, between Phoenix and Flagstaff, Ariz.

A solid forms from either a  liquid or a gas (the other two states of matter) because, as the energy of  the atoms decreases, they coalesce in the relatively ordered, three-  dimensional structure of a solid. All solids have the ability to support loads  applied either perpendicular (normal) or parallel (shear) to a surface. Sol�  ids can be crystalline (as in metals), amorphous (as in glass), or quasi�  crystalline (as in certain metal alloys), depending on the degree of order  in the arrangement of the atoms.</p><p>solid solution Solid form of a liquid solution. As with liquids, a ten�  dency for mutual solubility exists between any two coexisting solids (i.e.,  each can mix with the other); depending on the chemical similarities of  the solids, mutual solubility of two substances may be 100% (as between  silver and gold), or it may be near 0 (as between copper and bismuth).</p><p>solid-state device Electronic device that operates on the basis of the  electric, magnetic, or optical properties of a solid material, especially one  that uses a solid crystal in which an orderly three-dimensional arrangement  of atoms, ions, or molecules is repeated throughout the entire crystal.

A workers� strike  in 1980 at the Lenin Shipyards in Gdansk inspired other labour strikes in  Poland and compelled the government to agree to the workers� demands  for independent unions. Solidarity was founded to unite the regional trade  unions, and Lech Walesa was elected chairman. The movement won eco�  nomic reforms and free elections before pressure from the Soviet Union  forced the Polish government to suppress the union in 1981. The focus  of worldwide attention, it continued as an underground organization until  1989, when the government recognized its legality. In the free elections  of 1989, Solidarity candidates won most of the contested seats in the  assembly and formed a coalition government. In the 1990s the union�s  role diminished as new political parties emerged in a free Poland.</p><p>soliloquy \so- , li-l9- l kwe\ Dramatic monologue that gives the illusion of  being a series of unspoken reflections. An accepted dramatic convention</p><p>in the 16th� 17th centuries, it was used artfully by William Shakespeare to  reveal the minds of his characters. Pierre Corneille emphasized its lyricism,  while Jean Racine favoured it for dramatic effect. Overused in English  Restoration plays (1660-85), it fell into disfavour. Rejected by prose dra�  matists such as Henrik Ibsen, it was seldom used in late 19th-century natu�  ralist drama. Many 20th-century dramatists also avoided the soliloquy as  artificial, though Tennessee Williams and Arthur Miller, among others,  adapted it by introducing narrators who alternately mused on the action  and took part in it. It has been used by contemporary playwrights such  as John Guare and Brian Friel, and the illusion that the characters are con�  fiding in the audience has proved acceptable to a culture accustomed to  the interview and the documentary film.</p><p>solmization V.sal-ms-'za-shonN or solfeggio \sal-'fe-je-o\ System of  designating musical notes by syllable names. It may have been invented by  the 1 lth-century Italian monk Guido d�Arezzo when training his cathedral  singers. The syllables� ut, re, mi, fa, sol, la �were derived from the first  syllables of the lines of a hymn, each phrase of which began one note higher  than the previous phrase. This six-note series, or hexachord, facilitated the  sight-reading of music by allowing the singer always to associate a given  musical interval with any two syllables. The syllables are still in use, though  ut is usually replaced by the more singable do, and ti or si has been added  for the seventh scale degree.

Nearly all  that is known about him comes from the Bible (1 Kings 1-11 and 2  Chronicles 1-9). Through the efforts of his mother, Bathsheba, and the  prophet Nathan, Solomon was anointed king while David was still alive.  On accession to the throne, he liquidated his opponents ruthlessly and  installed friends in key posts. He established Israelite colonies outside his  kingdom�s borders, cooperating with such friendly rulers as the Queen of  Sheba to increase commerce. Fortification of his far-flung empire neces�  sitated a vast building program, the crowning achievement of which was  the Temple of Jerusalem. He reorganized the nation into 12 tribes with 12  administrative districts. He is said to have had a harem of 700 wives and  300 concubines. After the ascension to the throne of his son Rehoboam,  the northern tribes seceded and formed their own kingdom of Israel, bring�  ing an end to Solomon�s empire. His legendary wisdom is recorded in the  Book of Proverbs, and he is traditionally named as the author of the bib�  lical Song of Solomon. He was regarded as the greatest king of Israel.</p><p>Solomon Islands Island country, southwestern South Pacific Ocean.  (Another island group named Solomon Islands, which includes Bougain�  ville, is part of Papua New Guinea.) The country includes the islands of  Guadalcanal, Malaita, San Cristobal, Choiseul, Santa Isabel, and Rennell;  the Russell, Florida, Shortland, Santa Cruz, and New Georgia island  groups; and small islands and reefs. Area: 10,954 sq mi (28,370 sq km).  Population (2005 est.): 471,000. Capital: Honiara. The population is  largely Melanesian. Languages: English (official), Pijin (an English-based  pidgin), and more than 60 indigenous Melanesian languages. Religions:  Christianity (predominantly Protestant; also Roman Catholic); also tradi�  tional beliefs. Currency: Solomon Islands dollar. The Solomons group  comprises numerous volcanic islands arranged in two parallel chains that  converge in the southeast. They consist mostly of heavily wooded, moun�  tainous terrain drained by short, swift-flowing rivers. The climate is tropi�  cal. The economy is based on agriculture, fishing, and lumbering. Tourism  is increasing as cruise ships and visitors to World War II battlefields stop at  the islands. The country is a constitutional monarchy with one legislative  house; its chief of state is the British monarch represented by the governor-  general, and the head of government is the prime minister. The Solomon  Islands were probably settled c. 2000 bc by Austronesian people. Visited by  the Spanish in 1568, they were subsequently explored and charted by the  Dutch, French, and British. They were under British protection from 1893  as the British Solomon Islands. The Japanese invasion of 1942 ignited  some of the most bitter fighting in the Pacific during the war, particularly on  Guadalcanal. The protectorate became self-governing in 1976 and fully  independent in 1978. From 1999 ethnic fighting broke out in the Solomons;  New Zealand and Australian armed forces helped restore order.</p><p>Solomon's seal Any of about 25 species of herbaceous perennials that  make up the genus Polygonatum (lily family), found throughout the North-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1782 I Solon &#x25BA; Somali</p><p>em Hemisphere. Particularly common in the eastern U.S. and Canada,  Solomon�s seals flourish in damp, wooded areas and thickets. They have  thick, creeping rhizomes and tall, drooping stems, and they bear clusters  of white or greenish-white flowers in the axils of leaves, followed by  drooping red berries. Similar plants of the genus Smilacina, known as  false Solomon�s seal, bear their flower clusters at the tips of the stems.</p><p>Solon \'so-bn\ (b. c. 630�d. c. 560 bc) Athenian statesman, reformer,  and poet, known as one of the Seven Wise Men of Greece. He was of  noble descent but of moderate means. Though he held the office of archon  c. 594, he did not gain full power as a reformer and legislator until some</p><p>20 years later. He ended aristocratic rule and permitted participation by  all citizens who had achieved a measure of wealth, eliminating any blood�  line requirement. He replaced Draco�s code with more humane laws, freed  citizens enslaved for debt and redeemed their land, encouraged profes�  sions, and reformed coinage and weights and measures. Despite com�  plaints from all sides, the people abided by the changes. He apparently  left Athens for 10 years on a series of travels; on his return, he warned  Athens about his relative Peisistratus, who would become tyrant.</p><p>Solow Vs6-16\, Robert M(erton) (b. Aug. 23, 1924, Brooklyn, N.Y.,  U.S.) U.S. economist. He received his Ph.D. from Harvard University and  began teaching at the Massachusetts Institute of Technology in 1949.  Solow developed a mathematical model that could show the relative con�  tributions of various factors to sustained national economic growth. He  demonstrated that, contrary to traditional economic thinking, the rate of  technological progress is more important to growth than capital accumu�  lation or increases in labour. From the 1960s on, his studies were influ�  ential in persuading governments to invest in technological research and  development. In 1987 he was awarded the Nobel Prize in Economic Sci�  ences.</p><p>solstice \'sol-stis\ Either of the two moments in the year when the Sun�s  apparent path is farthest north or south from Earth�s Equator; also, either  of the two points along the ecliptic that the Sun passes through at these  times.

After making his piano debut at age 12, he stud�  ied piano with Bela Bartok and composition with Zoltan Kodaly. He was  Arturo Toscanini�s assistant at Salzburg (1936-37). In Switzerland when  World War II broke out, he returned to piano, winning the 1942 Geneva  International Competition. He led the Bavarian State Opera in Munich  (1945-52), and then he moved to Frankfurt (1952-61). As director of  Covent Garden (1961-71), he made the first complete recording of Rich�  ard Wagner�s Ring cycle (1958-65), which remains one of the celebrated  recordings of all time. Under Solti (1969-91), the Chicago Symphony  Orchestra won extraordinary praise and success.</p><p>solubility Degree to which a substance dissolves in a solvent to make a  solution (usually expressed as grams of solute per litre of solvent). Solu�  bility of one fluid (liquid or gas) in another may be complete (totally mis�  cible; e.g., methanol and water) or partial (oil and water dissolve only  slightly). In general, �like dissolves like� (e.g., aromatic hydrocarbons dis�  solve in each other but not in water). Some separation methods (absorption,  extraction) rely on differences in solubility, expressed as the distribution  coefficient (ratio of a material�s solubilities in two solvents). Generally,  solubilities of solids in liquids increase with temperature and those of gases  decrease with temperature and increase with pressure. A solution in which  no more solute can be dissolved at a given temperature and pressure is said  to be saturated (see saturation). See also Joel Hildebrand.</p><p>solution In chemistry, a homogeneous mixture of two or more sub�  stances in relative amounts that can vary continuously up to the limit of  solubility (saturation), if any, of one in the other. Most solutions are liq�  uids, but solutions also can be of GASes or solids �for example, air (com�  posed primarily of oxygen and nitrogen) or brass (composed chiefly of  copper and zinc; see alloy). In solutions comprising a solid dissolved in  a liquid, the liquid is the solvent, and the solid is the solute; if both com�  ponents are liquids, the one present in a smaller amount is usually con�  sidered the solute. If the saturation point is passed, excess solute separates  out. Substances with ionic bonds (e.g., salts) and many with covalent bonds  (e.g., acids, bases, alcohols) undergo dissociation into ions on dissolving  and are called electrolytes. Their solutions can conduct electricity and have</p><p>other properties that differ from those of nonelectrolytes. Solutions are  involved in most chemical reactions, refining and purification, industrial  processing, and biological processes.</p><p>Solutrean \s9-1ii-tre-9n\ industry Short-lived stone-tool industry that  flourished 17,000-21,000 years ago in southwestern France (e.g., at La  Solutre and Laugerie-Haute) and in nearby areas. The industry is of spe�  cial interest because of its particularly fine workmanship. In addition to  burins (chisel-like tools), scrapers, and borers, the Solutrean industry  exhibits blades formed in the shape of laurel or willow leaves and vari�  ous shouldered points. Some implements are so fine as to be useless as  tools and may instead have been luxury items.</p><p>Solvay process \'sal-,va\ or ammonia-soda process Modem  method of manufacturing sodium carbonate (soda ash), devised and com�  mercialized in Belgium by Ernest Solvay (1838-1922). Common salt  (sodium chloride) is treated with ammonia and then carbon dioxide, under  carefully controlled conditions, to form sodium bicarbonate and ammo�  nium chloride. When heated, the bicarbonate yields sodium carbonate, the  desired product; the ammonium chloride is treated with lime to produce  ammonia (for reuse) and calcium chloride. The process proved of great  commercial value, since large quantities of soda ash are used in making  glass, detergents, and cleansers. See also caustic soda.</p><p>solvent Substance, ordinarily a liquid, in which other materials dissolve  to form a solution. Polar solvents (e.g., water) favour formation of ions;  nonpolar ones (e.g., hydrocarbons) do not. Solvents may be predominantly  acidic, predominantly basic, amphoteric (both), or aprotic (neither).  Organic compounds used as solvents include aromatic compounds and  other hydrocarbons, alcohols, esters, ethers, ketones, amines, and nitrated  and halogenated hydrocarbons. Their chief uses are as media for chemi�  cal syntheses, as industrial cleaners, in extractive processes, in pharma�  ceuticals, in inks, and in paints, varnishes, and lacquers.</p><p>Solway Firth Inlet of the Irish Sea.

He fought  in World War II but was arrested in 1945 for criticizing Joseph Stalin. He  spent eight years in prisons and labour camps and three more in enforced  exile. With One Day in the Life of Ivan Denisovich (1962), based on his  labour-camp experiences, he emerged as an eloquent opponent of gov�  ernment repression. He was forced to publish later works abroad, includ�  ing The First Circle (1968), Cancer Ward (1968), and August 1914 (1971).  Publication of the first volume of The Gulag Archipelago (1973), one of  the greatest works in Russian prose, resulted in his being charged with  treason. Expelled from the Soviet Union in 1974, he lived in the U.S.,  enjoying worldwide fame, until 1994, when he returned home. In the late  1980s glasnost brought renewed access to his work in Russia but also a  loss of interest in it and in the prophetic role he claimed for himself in  Russian history. He was awarded the Nobel Prize for Literature in 1970.</p><p>soma In ancient Indian religion, an unidentified plant, the juice of which  was an offering of the Vedic sacrifices. Its stalks were pressed, and its  juice, filtered through wool, was mixed with water and milk. After being  offered as a libation to the gods, the remainder of the soma was consumed  by the priests and the sacrificer. It was highly valued for its exhilarating,  probably hallucinogenic, effect. The plant was believed to have been  delivered to the earth from heaven by an eagle. The personified deity  Soma was the master of plants, healer of disease, and bestower of riches.

Their language  is of the Cushitic branch of the Afroasiatic family. Numbering more than  seven million, the Somalis are divided into northern, central, and south�  ern groups. All have been Muslim since at least the 14th century. They  are primarily nomadic herdsmen who, because of intense competition for  scarce resources, have been extremely individualistic and frequently  involved in blood feuds or wars with neighbouring clans or peoples. A  second category of Somalis are the townspeople and agriculturalists of  the urban centres, especially along the coast of the Horn of Africa, many  of whom act as commercial middlemen between the Arab world and the  nomads of the interior.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Somalia &#x25BA; sonar I 1783</p><p>Somalia Country, eastern Africa. Located in the Horn of Africa, it  stretches from the Equator to the Red Sea. Area: 246,000 sq mi (637,000 sq  km). Population (2005 est.): 8,228,000 (excluding an estimated 400,000</p><p>cial; predominantly Sunni). Currency:</p><p>Somali shilling. Much of Somalia is semidesert. The central and southern  regions are flat, while the northern region rises to form rugged mountain  ranges. Only a tiny proportion of its land is arable, though more than half  is grazeable. Somalia has a developing mixed economy based largely on  livestock and agriculture. It is one of the poorest countries in the world.  Muslim Arabs and Persians first established trading posts along the coasts  in the 7th-10th centuries. By the 10th century Somali nomads occupied the  area inland from the Gulf of Aden, and the south and west were inhabited  by various groups of pastoral Oromo peoples. Intensive European explo�  ration began after the British occupation of Aden in 1839, and in the late  19th century Britain and Italy set up protectorates in the region. During  World War II the Italians invaded British Somaliland (1940); a year later  British troops retook the area. Britain administered the region until 1950,  when Italian Somaliland became a UN trust territory. In 1960 it was united  with the former British Somaliland, and the two became the independent  Republic of Somalia. Since then it has suffered political and civil strife,  including military dictatorship, civil wars, drought, and famine. No effec�  tive central government has existed since the early 1990s. In 1991 a Repub�  lic of Somaliland was proclaimed by a breakaway group on territory  corresponding to the former British Somaliland. It did not receive interna�  tional recognition, but it operated more smoothly than the area of tradi�  tional Somalia. A UN peacekeeping force intervened in 1992 to secure food  supplies; fighting continued, and the peacekeeping force left in 1995. The  country subsequently remained in turmoil.</p><p>Somaliland Vso-'ma-le-.landX Historical name for the region of eastern  Africa between the Equator and the Gulf of Aden that includes Somalia,  Djibouti, and southeastern Ethiopia. It has an area of about 300,000 sq  mi (777,000 sq km). The region probably formed part of the �Land of  Punt� known to the ancient Egyptians. Between the 7th and 12th centu�  ries, Muslim traders from Arabia and Iran settled on the coast and formed  sultanates. The nomadic Somali, who occupied the northern part of the  country between the 10th and 15th centuries, adopted Islam and served  in their armies. Gradually the sultanates themselves came under Somali  control. In the late 19th century, France, Italy, and Britain partitioned the  region among themselves. In 1960 British Somaliland and Italian Somali�  land were united to form the Republic of Somalia. French Somaliland</p><p>became independent as the Republic of Djibouti in 1977. In 1991 British  Somaliland announced that it was becoming an independent state, the  Republic of Somaliland; it was not internationally recognized.</p><p>somatotropin See growth hormone</p><p>Somerset Administrative (pop., 2001: 498,093), geographic, and his�  toric county, southwestern England.

He commanded the English forces that invaded Scotland and  sacked Edinburgh in 1544, and he decisively defeated the French at Bou�  logne in 1545. After Henry�s death (1547), he was named Protector of  England during the minority of Edward VI and acted as king in all but  name. When the Scots rejected his appeal for a voluntary union with  England, he invaded Scotland and won the Battle of Pinkie (1547). He  introduced moderate Protestant reforms, but these provoked Catholic  uprisings in western England. His land reforms were opposed by land-  owners and the duke of Northumberland, who had Somerset deposed from  the protectorate in 1549.

British and French forces launched a  frontal attack against an entrenched German army north of the Somme River  in France. A weeklong artillery bombardment was followed by a British  infantry assault on the still-impregnable German positions. Nearly 60,000  British casualties (including 20,000 killed) occurred on the first day. The  offensive gradually deteriorated into a battle of attrition, hampered by tor�  rential rains in October that made the muddy battlefield impassable. By  the time it was abandoned, the Allies had advanced only 5 mi (8 km). The  staggering losses included 650,000 German casualties, 420,000 British,  and 195,000 French.

Passive systems consist simply of receiv�  ing sensors that pick up the noise produced by the target (such as a sub�  marine or torpedo). A third kind of sonar, used in communication systems,  requires a projector and receiver at both ends. Sonar was first used to  detect submarines in 1916. Modern nonmilitary uses include fish finding,  depth sounding, mapping of the ocean floor, Doppler navigation (see  Doppler effect), and searching for wrecks or other objects in the oceans.</p><p>sonata Musical form for one or more instruments, usually consisting of  three or four movements. The name, Italian for �sounded (on an instru�  ment),� originally simply indicated nonvocal music and was used for a  confusing variety of genres into the late 17th century. In the 1650s two  types of ensemble sonatas began to be codified, the sonata da chiesa  (church sonata) and sonata da camera (chamber sonata). The former,  intended for church performance, was generally in four movements, two  of them slow; the latter was usually a suite of dances. The so-called solo  sonata (for soloist�usually violin�and continuo) and the trio sonata (for  two soloists and continuo) became standard. In the 1740s solo keyboard  sonatas began to be written. C.P.E. Bach established the three-movement  keyboard sonata as the norm, a status it would retain through the classi�  cal era. Duo sonatas in the same form, usually for violin and keyboard,  simultaneously became highly popular. Keyboard and duo sonatas have  remained the standard types to the present day. From Bach�s time onward,  the first movement was generally in allegro tempo and in sonata form.  The second movement was usually slow. The last movement was gener�  ally a minuet, rondo, or theme and variations. In a four-movement sonata,  the third was usually a minuet or scherzo. In these respects the sonata  paralleled genres such as the symphony and the string quartet.</p><p>sonata form or sonata-aNegro form Form of most first move�  ments and often other movements in musical genres such as the symphony,  concerto, string quartet, and sonata. The three parts of sonata form  evolved from the binary, or two-part, form prominent in the music of the  17th and early 18th centuries. In sonata form the first part, or exposition,  presents the basic thematic material of the movement, which is often  divided into two thematic groups, the second being in the dominant key  or�if the movement is in a minor key�in the relative major key. The sec�  ond section, or development, generally treats the earlier themes freely,  often moving to various different keys. It leads to the final section, or reca�  pitulation, when the tonic key returns and all the thematic material is  repeated in the tonic. Sonata form was the most common form for instru�  mental works in Western art music from c. 1760 to the early 20th century.</p><p>Sonderbund Vzon-dor-.buntX German "Separatist League"</p><p>League formed in 1845 by the seven Roman Catholic Swiss cantons. After  the Protestant cantons sought to prevent the Jesuits� takeover of religious  education in Lucerne, the Catholic cantons formed the Sonderbund, which  further angered the liberal cantons. In 1847 a reformist majority in the  Swiss Diet voted to dissolve the Sonderbund and expel the Jesuits. In  November 1847 the league took up arms, but its forces were quickly sub�  dued. The new Swiss constitution adopted in 1848 strengthened the cen�  tral government.</p><p>Sondheim Vsand- 1 hlm\ / Stephen (Joshua) (b.

He studied piano and  organ and at age 15 wrote his first musical under the tutelage of the musical  comedy author Oscar Hammerstein II, a family friend. After studies with  composer Milton Babbitt, he made his first mark on Broadway as lyricist for  West Side Story (1957) and later Gypsy (1959). He wrote both music and  lyrics for A Funny Thing Happened on the Way to the Forum (1962, Tony  Award), A Little Night Music (1973, Tony Award), Sweeney Todd (1979,  Tony Award), Sunday in the Park with George (1984, Pulitzer Prize), and  Into the Woods (1987), among other works. His stage works are known for  their intellectuality, musical complexity, and frequently dark tone.</p><p>song Short and usually simple piece of music for voice, with or with�  out instrumental accompaniment. Folk songs�traditional songs without  a known composer transmitted orally rather than in written form�have  existed for millennia but have left few traces in ancient sources. Virtually  all known preliterate societies have a repertory of songs. Folk songs often  accompany religious ceremonies, dancing, labour, or courting; they may  tell stories or express emotions; the music follows obvious conventions  and is often repetitive. Songs written by a particular composer or poet  generally are more sophisticated and are not attached to activities. In the  West the continuous tradition of secular art songs began with the trouba�  dours, trouveres, and minnesingers of the 12th�13th centuries. Polyphonic</p><p>songs, originating in the motet, began to appear in the 13th century. Com�  posers of the 14th century produced a great body of polyphonic songs in  the formes fixes. Later the Italian madrigal became the most distinguished  genre. Notated accompaniments to solo songs appeared in the 16th cen�  tury. The Romantic movement made the 19th century a golden age for the  art song, notably the German lied. In the 20th century the popular song  displaced the more cultivated art song, and popular music is today syn�  onymous with popular song.</p><p>Song dynasty or Sung \'suq\ dynasty (960-1279) Chinese dynasty  that united the entire country until 1127 and the southern portion until  1279, during which time northern China was controlled by the Juchen  tribes.

Wang Anshi worked for more equitable taxation and state-  centred solutions for China�s problems. Widespread printing brought  increased literacy and a broader elite, and private academies and state  schools sent increasing numbers of candidates through the Chinese exami�  nation system. In the 12th century, Zhu Xi systemized Neo-Confucianism.  The Song was also an era of scholarship: groundbreaking treatises on  architecture and botany were published, as was the famous history Zizhi  tongjian (�Comprehensive Mirror for Aid in Government�) of Sima  Guang.

It was a superior prefec�  ture under the Ming and Qing dynasties. Originally a major rice-growing  centre, by the 18th century it had gained an international reputation for  cotton textiles. During the Taiping Rebellion (1850-64) it was badly dam�  aged in the fighting to defend Shanghai; it is the burial place of the U.S.  adventurer Frederick T.

Shanghai�s phenomenal 19th-century growth took  away the town�s role as a commercial centre; although it remains domi�  nated by Shanghai, it has some industry and is a tourist destination for  Shanghai residents.</p><p>sonnet Fixed verse form having 14 lines that are typically five-foot  iambics rhyming according to a prescribed scheme. The sonnet is unique  among poetic forms in Western literature in that it has retained its appeal  for major poets for five centuries. It seems to have originated in the 13th  century among the Sicilian school of court poets. In the 14th century  Petrarch established the most widely used sonnet form. The Petrarchan  (or Italian) sonnet characteristically consists of an eight-line octave, rhym�  ing abbaabba, that states a problem, asks a question, or expresses an  emotional tension, followed by a six-line sestet, of varying rhyme  schemes, that resolves the problem, answers the question, or resolves the  tension.

His first major conquest  (1468) was the city of Timbuktu, one of the chief anchors of the declining  Mali empire. A seven-year siege of the city of Jenne (now Djenne) resulted  in its conquest in 1473. He spent most of his reign repulsing attacks on  his empire by the Dendi, the Fulani, the Mossi, and the Tuareg. Little is  known about his administration, but Arab chroniclers characterized him  as a cruel and capricious tyrant.</p><p>Sonora \so-'nor-9\ State (pop., 2000: 2,216,969), northwestern Mexico.

Charlie  Soong (1866-1918) trained in the U.S. to become a missionary. In China he  made his fortune as a publisher, initially of Bibles, and became a supporter  of Sun Yat-sen, whose Nationalist Party he helped finance. His first daughter  married a businessman who also provided financial support to the Nation�  alists; his second daughter, Soong Ch�ing-ling (Song Qingling; 1893�  1981), married Sun Yat-sen; and his third daughter, Soong Mei-ling (1897-  2003), became Chiang Kai-shek�s second wife. A son, T.V. Soong (1894-  1971), established the Central Bank of China and acted as finance minister  for the Nationalist government in the 1920s and foreign minister in the  1930s. The 1949 communist takeover divided the family: Ch�ing-ling, who  had earlier denounced the Nationalists for betraying Sun Yat-sen�s ideals,  remained on the mainland and was named honorary chairman of the Peo�  ple�s Republic shortly before her death. Mei-ling accompanied Chiang  Kai-shek to Taiwan and publicized his cause in the West; as Madam  Chiang, she became extremely popular in the U.S. T.V.

Daughter of Tsai - Alexis, she objected to the succession of her half  brother Peter I (the Great) as tsar (1682) and instigated an uprising by the  streltsy (household troops). She arranged to have her brother Ivan V pro�  claimed coruler with Peter and assumed the role of regent. With help from  her chief adviser and lover, Vasily Golitsyn, she promoted the develop�  ment of industry and concluded peace treaties with Poland (1686) and  China (1689). After sponsoring two disastrous military campaigns against  the Crimean Tatars (1687, 1689), she tried to regain her influence by  inciting the streltsy to oust Peter and his advisers. She was instead over�  thrown by Peter in 1689 and forced to enter a convent.</p><p>sophists Vsa-fists\ Group of itinerant professional teachers, lecturers,  and writers prominent in Greece in the later 5th century bc. The sophis�  tic movement arose at a time when there was much questioning of the  absolute nature of familiar values and ways of life. An antithesis arose  between nature and custom, tradition, or law, in which custom could be  regarded either as artificial trammels on the freedom of the natural state  or as beneficial and civilizing restraints on natural anarchy. Both views  were represented among the sophists, though the former was the more  common. Their first and most eminent representative was Protagoras;  other notable sophists include Gorgias of Leontini, Prodicus, Hippias,  Antiphon, Thrasymachus, and Critias. A later �second sophistic school�  existed in the 2nd century ad.</p><p>Sophocles Vsa-fo-.klezV (b. c. 496, Colonus, near Athens�d. 406 bc,  Athens) Greek playwright. With Aeschylus and Euripides, he was one of the  three great tragic playwrights of Classical Athens. A distinguished public  figure in Athens, he served successively in important posts as a treasurer,  commander, and adviser. He competed in dramatic festivals, where he  defeated Aeschylus to win his first victory in 468 bc. He went on to  achieve unparalleled success, writing 123 dramas for dramatic competi�  tions and achieving more than 20 victories. Only seven tragedies survive  in their entirety: Antigone, Ajax, Electra, The Trachinian Women, Philoc-  tetes, Oedipus at Colonus, and Oedipus the King, his best-known work.  He increased the size of the chorus and was the first to introduce a third  actor onstage. For their supple language, vivid characterization, and for�  mal perfection, his works are regarded as the epitome of Greek drama.</p><p>soprano Highest vocal register, ranging from about middle C to the  second A above it. Sopranos are normally female but may also include  boy sopranos and (previously) castrati (see castrato).

He discovered Marxism in 1893 but was disgusted by  what he saw as the left�s exploitation of the Alfred Dreyfus affair. By 1902  he was an enthusiastic supporter of revolutionary syndicalism. Sorel�s  thought is characterized by a moralistic hatred of social decadence and res�  ignation. He held that human nature was not innately good; he therefore  concluded that a satisfactory society was not likely to evolve but would  have to be brought about by revolutionary action. After 1909 Sorel became  disenchanted with syndicalism, and with some hesitation he joined the  monarchist movement, which sought to reestablish a traditional morality.  After the outbreak of the Russian Revolution of 1917, Sorel declared him�  self for the Bolsheviks, who he thought might be capable of precipitating the  moral regeneration of mankind. His most important work, Reflections on  Violence (1908), develops his notion of violence as the revolutionary denial  of the existing social order. Sorel�s ideas were appropriated (and perverted)  by Benito Mussolini, who used them in support of fascism.</p><p>sorghum Vsor-gamV Cereal grain plant of the family Poaceae (or  Gramineae), probably native to Africa, and its edible starchy seeds. All  types raised chiefly for grain belong to the species Sorghum vulgare,  which includes varieties of grain sorghums and grass sorghums (grown  for hay and fodder), and broomcom (used in making brooms and brushes).  The strong grass usually grows 2-8 ft (0.5-2.5 m) or higher. The seeds  are smaller than those of wheat. Though high in carbohydrates, sorghum  is of lower feed quality than com. Resistant to drought and heat, sorghum  is one of Africa�s major cereal grains. It is also grown in the U.S., India,  Pakistan, and northern and northeastern China. Substantial quantities are  also grown in Iran, the Arabian Peninsula, Argentina, Australia, and south�  ern Europe.

In 1985 he signed with the Texas Rangers, with whom he made his  professional debut in 1989; he was soon traded to the Chicago White Sox  and then in 1992 to the Chicago Cubs. In 1993 the right fielder became  the Cubs� first player to hit 30 home runs and steal 30 bases in one sea�  son, a feat he repeated in 1994. In 1998 he dramatically battled Mark  McGwire for the season home-run record (later broken by Barry Bonds);  Sosa finished the year with 66 home runs, earning him the National  League�s Most Valuable Player award. In 1999 he became the first player  to hit more than 60 home runs in each of two seasons.

In the 19th  and early 20th centuries, Sotheby�s concentrated on books, manuscripts,  and prints. After World War I it specialized in 19th- and 20th-century  works, particularly Impressionist paintings. It opened an office in New  York City in 1955, and in 1964 it acquired Parke-Bemet, the premier U.S.  art auction house. A.

He joined the 1514 expedition of Pedro Arias Davila  (1440-1531) to the West Indies, and in Panama he quickly made his mark  as a trader and explorer. By 1520 he had accumulated a small fortune  through his slave trading in Nicaragua and on the Isthmus of Panama. He  joined Francisco Pizarro on an expedition to conquer Peru in 1532, return�  ing to Spain in 1536 with great wealth. Commissioned by the Spanish  crown to conquer what is now Florida, he departed in 1538 in command  of 10 ships and 700 men. On that expedition he explored the extensive  region that was to become the southeastern U.S. and discovered the Mis�  sissippi River for Europeans. Overcome by fever, he died in Louisiana  and was buried in the Mississippi River.</p><p>soul Immaterial aspect or essence of a person, conjoined with the body  during life and separable at death. The concept of a soul is found in nearly  all cultures and religions, though the interpretations of its nature vary  considerably. The ancient Egyptians conceived of a dual soul, one sur�  viving death but remaining near the body, while the other proceeded to  the realm of the dead. The early Hebrews did not consider the soul as  distinct from the body, but later Jewish writers perceived the two as sepa�  rate. Christian theology adopted the Greek concept of an immortal soul,  adding the notion that God created the soul and infused it into the body  at conception. In Islam the soul is believed to come into existence at the  same time as the body but is everlasting and subject to eternal bliss or  torment after the death of the body. In Hinduism each soul, or atman, was</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>soul music &#x25BA; South Africa I 1787</p><p>created at the beginning of time and imprisoned in an earthly body; at  death the soul is said to pass to a new body according to the laws of karma.  Buddhism negates the idea of a soul, asserting that any sense of an indi�  vidual self is illusory.</p><p>soul music Style of U.S. popular music sung and performed primarily  by African American musicians, having its roots in gospel music and rhythm  and blues. The term was first used in the 1960s to describe music that  combined rhythm and blues, gospel, jazz, and rock music and that was  characterized by intensity of feeling and earthiness. In its earliest stages,  soul music was found most commonly in the South, but many of the young  singers who were to popularize it migrated to cities in the North. The  founding of Motown in Detroit, Mich., and Stax-Volt in Memphis, Tenn.,  did much to encourage the style. Its most popular performers include James  Brown, Ray Charles, Sam Cooke, and Aretha Franklin.</p><p>sound Mechanical disturbance that propagates as a longitudinal wave  through a solid, liquid, or gas. A sound wave is generated by a vibrating  object. The vibrations cause alternating compressions (regions of crowd�  ing) and rarefactions (regions of scarcity) in the particles of the medium.  The particles move back and forth in the direction of propagation of the  wave. The speed of sound through a medium depends on the medium�s  elasticity, density, and temperature. In dry air at 32 �F (0 �C), the speed of  sound is 1,086 feet (331 metres) per second. The frequency of a sound  wave, perceived as pitch, is the number of compressions (or rarefactions)  that pass a fixed point per unit time. The frequencies audible to the human  ear range from approximately 20 hertz to 20 kilohertz. Intensity is the  average flow of energy per unit time through a given area of the medium  and is related to loudness. See also acoustics; ear; hearing; ultrasonics.</p><p>Sound, The See 0resund</p><p>sound barrier Sharp rise in aerodynamic drag that occurs as an air�  craft approaches the speed of sound. At sea level the speed of sound is  about 750 miles (1,200 km) per hour, and at 36,000 feet (11,000 metres)  it is about 650 miles (1,050 km) per hour. The sound barrier was formerly  an obstacle to supersonic flight. If an aircraft flies at somewhat less than  sonic speed, the pressure waves (sound waves) it creates outspeed their  sources and spread out ahead of it. Once the aircraft reaches sonic speed  the waves are unable to get out of its way. Strong local shock waves form  on the wings and body; airflow around the craft becomes unsteady, and  severe buffeting may result, with serious stability difficulties and loss of  control over flight characteristics. Generally, aircraft properly designed  for supersonic flight have little difficulty in passing through the sound  barrier, but the effect on those designed for efficient operation at subsonic  speeds may become extremely dangerous. The first pilot to break the  sound barrier was Chuck Yeager (1947), in the experimental X-l aircraft.</p><p>sound card or audio card Integrated circuit that generates an audio  signal and sends it to a computer�s speakers. The sound card can accept an  analog sound (as from a microphone or audio tape) and convert it to digital  data that can be stored in an audio file, or accept digitized audio signals (as  from an audio file) and convert them to analog signals that can be played on  the computer�s speakers. On a personal computer, the sound card is usually  a separate circuit board that is plugged into the motherboard.</p><p>sound effect Artificial imitation of sound to accompany action and  supply realism in a dramatic production. Sound effects were first used in  the theatre, where they can represent a range of action too vast or diffi�  cult to present onstage, from battles and gunshots to trotting horses and  rainstorms. Various methods were devised by backstage technicians to  reproduce sounds (e.g., rattling sheet metal to create thunder); today most  sound effects are reproduced by recordings. An important part of old-  fashioned radio dramas, sound effects are still painstakingly added to  television and movie soundtracks.</p><p>sound reception See hearing</p><p>Souphanouvong Vsii-'pa-nu-.voqX (b.

South Africa has three major zones: the  broad interior plateau, the surrounding mountainous Great Escarpment,  and a narrow belt of coastal plain. It has a temperate subtropical climate. It  is one of the world�s major producers and exporters of gold, coal, dia�  monds, platinum, and vanadium. It is a multiparty republic with two leg�  islative houses; its head of state and government is the president. San and  Khoekhoe (Khoisan speakers) roamed the area as hunters and gatherers in  the Stone Age, and the latter had developed a pastoralist culture by the time  of European contact. By the 14th century, peoples speaking Bantu lan�  guages had settled in the area and developed gold and copper mining and an  active East African trade. In 1652 the Dutch established a colony at the  Cape of Good Hope; the Dutch settlers became known as Boers (Dutch:  �Farmers�) and later as Afrikaners (for their Afrikaans language). In 1795  British forces captured the cape. In 1836 Dutch settlers seeking new land  made the Great Trek northward and established (1838) the independent  Boer republics of Orange Free State and the South African Republic (later  the Transvaal region), which the British annexed as colonies by 1902 fol�  lowing the Soutfi African War. In 1910 the British colonies of Cape  Colony, Transvaal, Natal, and Orange River were unified into the new  Union of South Africa, which became independent and withdrew from the  Commonwealth in 1961. Throughout the 20th century, South African poli�  tics were dominated by the question of maintaining white European  supremacy over the country�s black majority, and in 1948 South Africa for�  mally instituted apartheid. Faced by increasing worldwide condemnation, it  began dismantling the apartheid laws in 1990. In free elections in 1994,  Nelson Mandela became the country�s first black president. A permanent  nonracial constitution was promulgated in 1997.</p><p>South African War or Boer War War fought between Great Brit�  ain and the two Boer (see Afrikaner) republics�the South African Repub�  lic (Transvaal) and the Orange Free State �from 1899 to 1902. It was  precipitated by the refusal of the Boer leader Paul Kruger to grant politi�  cal rights to Uitlanders (�foreigners,� mostly English) in the interior min�  ing districts and by the aggressiveness of the British high commissioner,  Alfred Milner. Initially the Boers defeated the British in major engage�  ments and besieged the key towns of Ladysmith, Mafikeng, and Kimber�  ley; but British reinforcements under H.H. Kitchener and F.S. Roberts  relieved the besieged towns, dispersed the Boer armies, and occupied  Bloemfontein, Johannesburg, and Pretoria (1900). When Boer commando  attacks continued, Kitchener implemented a scorched-earth policy: Boer  farms were destroyed and Boer civilians were herded into concentration  camps. More than 20,000 men, women, and children (including black  Africans) died as a result, causing international outrage. The Boers finally  accepted defeat at the Peace of Vereeniging.</p><p>South America Continent, Western Hemisphere. The world�s fourth  largest continent, it is bounded by the Caribbean Sea to the northwest, the  Atlantic Ocean to the northeast, east, and southeast, and the Pacific Ocean  to the west. It is separated from Antarctica by the Drake Passage and is  joined to North America by the Isthmus of Panama. Area: 6,895,210 sq mi  (17,858,520sq km). Pop., 2002 est.: 350,977,000. Four main ethnic groups  have populated South America: Indians, who were the continent�s pre-  Columbian inhabitants; Spanish and Portuguese who dominated the con�  tinent from the 16th to the early 19th century; Africans imported as slaves;  and the postindependence immigrants from overseas, mostly Germans and  southern Europeans but also Lebanese, South Asians, and Japanese. Nine-  tenths of the people are Christian, the vast majority of whom are Roman  Catholic. Spanish is the official language everywhere except in Brazil (Por�  tuguese), French Guiana (French), Guyana (English), and Suriname  (Dutch); some Indian languages are spoken. South America has three major  geographic regions. In the west, the Andes Mountains, which are prone to  seismic activity, extend the length of the continent; Mount Aconcagua, at  22,834 ft (6,960 m), is the highest peak in the Western Hemisphere. High�  lands lie in the north and east, bordered by lowland sedimentary basins that  include the Amazon River, the world�s largest drainage basin, and the Pampas  of eastern Argentina, whose fertile soils constitute one of South America�s  most productive agricultural areas. Other important drainage systems  include those of the Orinoco and Sao Francisco rivers and the Parana-  Paraguay-Rio de la Plata system. Four-fifths of South America lies within  the tropics, but it also has temperate, arid, and cold climatic regions. Less  than one-tenth of its land is arable, producing mainly com (maize), wheat,  and rice, and about one-fourth is under permanent pasture. About half is</p><p>covered by forest, mainly the enormous but steadily diminishing rainforest  of the Amazon basin. Almost one-fourth of all the world�s known animal  species live in the continent�s rainforests, plateaus, rivers, and swamps.  South America has one-eighth of the world�s total deposits of iron and one-  fourth of its copper reserves. Exploitation of these and numerous other  mineral resources are important to the economies of many regions. Com�  mercial crops include bananas, citrus fruits, sugar, and coffee; fishing is  important along the Pacific coast. Trade in illegal narcotics (mostly for  export) is a major source of revenue in some countries. Most countries have  free-market or mixed (state and private enterprise) economies. Income  tends to be unevenly distributed between large numbers of poor people and  a small number of wealthy families, with the middle classes, though grow�  ing, still a minority in most countries. Asiatic hunters and gatherers are  thought to have been the first settlers, probably arriving less than 12,000  years ago. The growth of agriculture from c. 2500 bc (it had begun some  6,000 years earlier) initiated a period of rapid cultural evolution whose  greatest development occurred in the central Andes region and culminated  with the Inca empire. European exploration began when Christopher Colum�  bus landed in 1498; thereafter Spanish and Portuguese adventurers (see  coNQUiSTADORes) opened it for plunder and, later, settlement. According to  terms of the Treaty of Tordesillas, Portugal received the eastern part of the  continent, while Spain received the rest. The Indian peoples were deci�  mated by this contact, and most of those who survived were reduced to a  form of serfdom. The continent was free of European rule by the early  1800s except for the Guianas. Most of the countries adopted a republican  form of government; however, social and economic inequalities or border  disputes led to periodic revolutions in many of them, and by the early 20th  century most had fallen under some form of autocratic rule. All joined the  United Nations after World War II (1938-45), and all joined the Organi�  zation of American States in 1948. By the second half of the 20th century  most countries had begun to integrate their economies into world markets,  and by the 1990s most had embraced democratic rule.

Myths of the popular gods, Vishnu and  Shiva, in the Puranas (ancient tales) and the Mahabharata and Ramayana  epics, supply material for representational and dramatic arts. The Rama�  yana is often considered the first work in the kavya poetic style; kavya  compositions must convey different rasa (sentiments) and also induce the  appropriate rasa in the audience. The Dravidian languages of the south,  including Tamil and Telegu, provided some enduring works, particularly  the devotional poems of the Tamil Alvars and Nayannars from the 7th  through the 9th century. The introduction of Persian by Muslim conquer�  ors led to the development of Urdu. Following in the Persian tradition,  Urdu poets particularly favoured the ghazal, a love poem of great metric  and rhythmic subtlety. The Nanya-Nastra established the rules for clas�  sical dance and drama, the most popular form of which was the nanaka,  or heroic tale. From the 14th century onward the nanaka lost ground to  popular folk theatre, but elements of classical drama persist. Dance tra�  ditionally requires musical accompaniment, though players and vocalists  take their lead from the rhythm of the dancers� feet and not vice versa.  Central to South Asian music is the concept of modes known as raga.  Rhythm in South Asian music, like the construction of scales, is additive.  The music is basically monodic, consisting essentially of a single melody  against a drone, though the drum part may virtually constitute another  voice. Music is generally for entertainment, but it is nevertheless closely  linked to Hinduism. Northern India�s most characteristic structure, a  temple with a heavily decorated tower, reached its stylistic height in the  7th�11th centuries. The extension of Islam into India in the 11th and 12th  centuries introduced typical Muslim architectural forms (e.g., the dome  and pointed arch) and decoration. Such masterworks as the Taj Mahal  resulted from the rule of the Muslim Mughal dynasty in the 16th-18th  centuries. Traditionally, visual artists produced works for patrons, and  sacred written canons guided their works� proportions, iconography, and  other artistic considerations. Since early in the region�s history, wall paint�  ings and miniatures painted on palm leaves or paper were prominent, but  sculpture was the favoured medium. Sculptures were largely religious and  essentially symbolic and abstract. Works displaying Hindu and Buddhist  imagery flourished in the Golden Age of India in the 4th-5th centuries.  Islamic influences were incorporated into traditional styles after the Mus�  lim invasions of the 12th century. At the end of the 19th century, rising  Indian nationalism led to a conscious revival of native arts traditions,  though more recently artists have assimilated elements of European art</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1789</p><p>1790 I South Australia &#x25BA; South West Africa People's Organization</p><p>styles.

It covers an area of 379,720 sq mi (983,470 sq km), and its capital is  Adelaide. The Dutch visited the coast in 1627. British explorers arrived in  the early 1800s, and it was colonized as a British province in 1836. Its  vast interior, a large part of which is barren, includes Lake Eyre and the  Flinders Ranges. A major world source of opals, it also produces most of  the wine and brandy consumed in Australia. It has the country�s largest  shipyards. It became a state of the Commonwealth of Australia in 1901.  Its southeastern part has become industrialized since World War II.</p><p>South Bend City (pop., 2000: 107,789), northern Indiana, U.S. It is  situated on the St. Joseph River. A fur-trading post was established at the  site in 1820. The city�s highly industrialized economy has roots in the  pioneering companies founded there in the 19th century, including Stude-  baker Brothers Manufacturing Co. (later an auto plant) and Singer Co., a  sewing machine manufacturer. The city serves as the trade and financial  focus of southern Michigan as well as northern Indiana, a region known  as Michiana. Nearby is the University of Notre Dame.</p><p>South Carolina State (pop., 2000:4,012,012), southeastern U.S. It cov�  ers 31,113 sq mi (80,583 sq km) and is an original state of the Union; its  capital is Columbia. South Carolina is bounded on the north by North Caro�  lina and on the southwest by Georgia; the Atlantic Ocean is to the southeast.  The state comprises a broad coastal plain with a rolling piedmont farther  inland. At the time of European contact the area was inhabited by Sioux,  Iroquois, and Muskogean Indians. Spanish and French settlements were  established and abandoned in the 16th century; the first permanent Euro�  pean settlement was made by the English in 1670 at Charles Town, moved  to the present site of Charleston in 1680. Several military campaigns were  fought in South Carolina during the American Revolution. In 1788 South  Carolina became the eighth state to ratify the U.S. Constitution, and in 1860  it became the first state to secede from the Union. The initial action of the  American Civil War occurred there at Fort Sumter. It was readmitted to the  Union in 1868. Constitutional revisions in 1895 disenfranchised almost all  of the state�s blacks, and a rigid policy of racial segregation persisted until  the mid-1960s, when the national civil rights movement began to have some  effect in ameliorating racist policies. South Carolina is a leader in U.S. tex�  tile manufacturing and has a large industrial base. Tourism is its second  largest industry. Agriculture also contributes to the economy; major crops  include tobacco, soybeans, and cotton.</p><p>South China Sea See China Sea</p><p>South Dakota State (pop., 2000: 754,844), north-central U.S. It cov�  ers 77,116 sq mi (199,730 sq km); its capital is Pierre. South Dakota is  bordered on the north by North Dakota, on the east by Minnesota and  Iowa, on the south by Nebraska, and on the west by Wyoming and Mon�  tana. The state has three main regions�the eastern prairie; the central  Great Plains, which contain the Badlands; and the Black Hills to the west.  The Missouri River bisects it from north to south. The French explored the  area in the 18th century and sold it to the U.S. as part of the Louisiana  Purchase in 1803. The Lewis and Clark Expedition spent about seven weeks  there in 1804. The Dakota Territory was created in 1861, but settlement  was sparse until the Black Hills gold rush of 1875-76 swelled the popu�  lation. Intermittent wars between the Indians and immigrant whites  occurred until the massacre at Wounded Knee in 1890. South Dakota  became the 40th U.S. state in 1889. Farming and related industries form  the state�s economic base. It is a leader in cattle and hog production, and  its main crops are grains. Tourism is a major industry; attractions include  Mount Rushmore, Wind Cave National Park, Badlands National Park, and  Jewel Cave National Monument.</p><p>South Georgia Mountainous, barren island, southern Atlantic Ocean.  It is located about 800 mi (1,300 km) east-southeast of the Falkland (Mal�  vinas) Islands. Together with the South Sandwich Islands, some 500 mi  (800 km) to the southeast, it constitutes a British overseas territory. With  an Antarctic climate, it has perpetual snow covering three-fourths of the  island. It is home to reindeer, several penguin and seal species, and abun�  dant marine life. Capt. James Cook claimed it for Britain in 1775, and  Ernest Shackleton first crossed it in 1916 while in search of aid for his  ill-fated expedition; Shackleton died on the island on a later expedition  and was buried there. Formerly a whaling base, it is now the site of an  Antarctic research station.</p><p>South Indian bronze Any of the cult images that rank among the  finest achievements of Indian visual  art. Most of the figures represent  Hindu divinities, especially various  iconographic forms of the god Shiva  and Lord Vishnu, with their consorts  and attendants. The images were  produced in large numbers from the  8th to the 16th century, principally in  the Thanjavur and Tiruchchirappalli  districts of modern Tamil Nadu, and  maintained a high standard of excel�  lence for almost 1,000 years. The  icons range from small household  images to almost life-size sculptures  intended to be carried in temple pro�  cessions.</p><p>South Island Island (pop., 2001  prelim.: 942,213), larger and south�  ernmost of the two principal islands  of New Zealand. Separated from the  North Island by Cook Strait, it has an  area of 58,676 sq mi (151,971 sq  km). Mountains, including the  Southern Alps, occupy almost three-  quarters of the island. Its main cities  are Christchurch and Dunedin. Fiord�  land National Park in the southwest  contains numerous coastal fjords and  high lakes.</p><p>South Korea See South Korea</p><p>South Orkney Islands Island group, southern Atlantic Ocean.  Located southeast of South America, the South Orkneys are composed of  two large islands (Coronation and Laurie) and many smaller islands; they  form part of the British Antarctic Territory. Barren and uninhabited, the  islands have a total area of 240 sq mi (620 sq km). They were part of the  Falkland Islands Dependencies until 1962. Signy Island is used as a base  for Antarctic exploration.</p><p>South Platte River River, Colorado and western Nebraska, U.S. The  river rises in central Colorado and flows southeast and then northeast  across the Nebraska boundary to join the North Platte River and form the  Platte River. The South Platte is 442 mi (711 km) long. Its reservoirs and  dams, particularly around Denver, are used for flood control, irrigation,  and power generation.</p><p>South Pole Southern extremity of the Earth�s axis, located at latitude  90� S. It is the southern point from which all meridians of longitude start.  The area around it is a lofty plateau in west-central Antarctica, with ice  as much as 8,850 ft (2,700 m) thick. It has six months of complete day�  light and six months of total darkness each year. It was first reached by  the Norwegian explorer Roald Amundsen in 1911, one month before the  expedition led by British explorer Robert Falcon Scott; U.S. explorer Rich�  ard E. Byrd flew to the pole in 1929. The geographic pole does not coin�  cide with the magnetic South Pole, which in the early 21st century was  located on the Adelie Coast about 64�30' S, 137�50' E; it moves about 8  mi (13 km) to the northwest each year. The geomagnetic South Pole also  moves; during the early 1990s it was located about 79�13' S, 108�44' E,  in 2000 it was 65�39' S, 140� 01' E, and by 2005 it was back to about  79�45'S, 108�13'E.</p><p>South Sea Bubble (1720) Speculation mania that caused financial ruin  for many British investors. Parliament�s acceptance of a proposal by the  South Sea Co. to take over the British national debt resulted in an imme�  diate rise in its stock. After soaring from 128V&amp; to over 1,000 in nine  months, the bubble of overvalued stock burst and the price per share  dropped to 124, dragging other stocks down and leaving many investors  ruined.

It lost its administrative functions in 1986 and is now  only a geographic and ceremonial county; its administrative seat was  Barnsley. South Yorkshire extends from the Pennine moorlands in the west  to lowland marshes in the east. The Romans built roads and forts in the  area, and Anglian and later Scandinavian settlers cleared woodlands. In  the 19th century the region grew as a major industrial area, and the River  Don valley became the focus of iron- and steelworks extending east from  Sheffield. Today South Yorkshire includes most of England�s coalfields;  its industries produce iron, steel, and cutlery.</p><p>Southampton City and unitary authority (pop., 2001: 217,478), historic  county of Hampshire, England. First settled by Romans, it was chartered (c.  1155) by King Henry II and incorporated in 1445. In the Middle Ages its  location on the English Channel helped it to become a major British port.  Southampton declined in the 17th�18th centuries but revived in the 19th  with the arrival of railways. It is England�s second largest port. Historic  buildings include the 11th-century St. Michael�s Church and the 12th-  century King John�s Palace, one of Britain�s oldest domestic buildings.</p><p>Southampton, Henry Wriothesley, 3rd earl of (b. Oct. 6,  1573, Cowdray, Sussex, Eng.�d. Nov. 10, 1624, Bergen op Zoom, Neth.)  English nobleman, patron of William Shakespeare. Grandson of the 1st earl  of Southampton, he became a favourite of Elizabeth I. He was a liberal  patron of writers, including Thomas Nashe. Shakespeare dedicated two  long poems to him (1593, 1594), and he has often been identified as the  noble youth addressed in most of Shakespeare�s sonnets. He accompa�  nied the 2nd earl of Essex on expeditions to Cadiz and the Azores (1596,  1597). For supporting the Essex rebellion (1601), he was imprisoned  (1601-03); following James I�s accession, he regained his place at court.  He became a privy councillor in 1619, but he lost favour by opposing the  1st duke of Buckingham. He and his son volunteered to fight for the United  Provinces against Spain, but, soon after landing in the Netherlands, they  both died of fever.</p><p>Southampton, Thomas Wriothesley Vrat-sle, 'ri-9th-sle\, 1st  earl of (b. Dec. 21, 1505, London, Eng.�d. July 30, 1550, London)  English politician. He followed his father, a herald, into royal service and  became personal secretary to Thomas Cromwell (1533), whom he suc�  ceeded as a secretary of state to Henry VIII (1540). Wriothesley became  one of Henry�s leading councillors and was appointed lord chancellor of  England (1544-47). After Henry�s death, he was created earl of  Southampton (1547) by the duke of Somerset, but he was deprived of the  chancellorship. He supported Somerset�s overthrow in 1549 but was  excluded from the privy council in 1550.</p><p>Southampton Island Island, Keewatin region, Nunavut, Canada.  Lying at the entrance to Hudson Bay, the island is roughly triangular and  has an area of 15,913 sq mi (41,214 sq km). Its plateau in the northeast,  with 1,000-ft (300-m) coastal cliffs, gradually slopes to lowlands in the  south. Its coastal waters are noted for Arctic char fishing.</p><p>Southeast Asia Vast region of Asia lying east of the Indian subcon�  tinent and south of China. It includes a mainland area (also called Indo�  china) and a string of archipelagoes to the south and east and is generally  taken to include Myanmar (Burma), Thailand, Cambodia, Laos, Vietnam,  Malaysia, Singapore, Indonesia, Brunei, and the Philippines. For centuries the  mainland portion was the site of numerous indigenous dynasties, but in  the 19th century all but Thailand (Siam) came under the control of Euro�  pean powers, notably France (see French Indochina); all areas became  independent after 1945.</p><p>Southeast Asia Treaty Organization (SEATO) Regional  defense organization (1955-77) comprising Australia, France, New  Zealand, Pakistan, the Philippines, Thailand, Britain, and the U.S. It was  founded as part of the Southeast Asia Collective Defense Treaty in order  to protect the region from communism. Vietnam, Cambodia, and Laos  were not considered for membership, and other countries in the region  preferred membership in the nonaligned movement. SEATO had no stand�</p><p>ing forces, but its members engaged in combined military exercises. Paki�  stan withdrew in 1968, and France suspended financial support in 1975.  The organization was disbanded officially in 1977.</p><p>Southeast Asian arts Literary, performing, and visual arts of Myan�  mar (Burma), Thailand, Laos, Cambodia, Vietnam, Malaysia, Singapore,  and the Philippines. The �classical� literatures of Southeast Asia can be  divided into three major regions: the Sanskrit region of Cambodia and  Indonesia; the region of Burma where Pali, a dialect related to Sanskrit,  was used as a literary and religious language; and the Chinese region of  Vietnam. The Mahabharata, Ramayana, Jatakas, and local legendary  tales are expounded in the performing arts of the region. Dance techniques  of the region minimize the mudras (gestures) of Indian classicism to  emphasize grace of movement over theme. Regional variations of temple  and court dance vie with local developments. Numerous theatrical forms  are vehicles for social criticism; most remarkable is wayang, or shadow  play, in which puppetry has been fused with dance and drama in a unique  form of entertainment. Music is generally coordinated with the dramatic  arts, resulting in great rhythmic but slight melodic content. The earliest  visual arts of the region were wood carvings featuring supernatural and  animal imagery developed and shared by the various tribal peoples. A  second tradition emerged after Indian artists and artisans followed trad�  ers to Southeast Asia in the first centuries ad. Within a short time, South�  east Asians were producing their own distinctive local versions of Indian  styles, sometimes rivaling Indian artists with their skill, finesse, and inven�  tion on a colossal scale. With the introduction of Hinduism and Buddhism,  temple building, sculpture, and painting flourished from the 1st through  the 13th century. The Indian royal temple, which dominated Southeast  Asian culture, typically stood on a terraced plinth, upon which towered  shrines could multiply. About ad 800 the Cambodian king Jayavarman II  built a brick mountain for a temple group. This plan was furthered when  foundations were laid for Angkor, a scheme based on a grid of reservoirs  and canals. Successive kings built more temple mountains there, culmi�  nating in Angkor Wat. Among Southeast Asia�s most impressive sites is  the city of Pagan in Burma, with many brick and stucco Buddhist temples  and stupas built 1056-1287.</p><p>Southeast Indian Any member of the aboriginal North American  Indians who inhabited what is now the southeastern U.S. The Southeast  was one of the more densely populated areas of native North America,  having an aboriginal population conservatively estimated at 120,000. The  bulk of this population resided inland, where advantage could be taken  of extensive game resources, wild plant foods, and an abundance of arable  land. Only the non-horticultural peoples of south Florida appear to have  satisfactorily adjusted to a basically maritime way of life. Groups within  this region included the Caddo, Catawba, Cherokee, Chickasaw, Choctaw,  Creek, Natchez, and Seminole.</p><p>Southend-on-Sea Town and unitary authority (pop., 2001: 160,256),  geographic and historic county of Essex, southeastern England. It lies on  the Thames estuary and the North Sea. The nearest seaside resort to Lon�  don, it attracts millions of visitors, and there are many resident commut�  ers. It is noted for its 1.3-mi (2.2-km) pier as well as its beaches and  gardens; yachting is popular.

It extends  almost the entire length of the island, and it is the highest range in Aus�  tralasia. It has elevations from 3,000 ft (900 m) to over 10,000 ft (3,050  m), culminating in Mount Cook at 12,316 ft (3,754 m) high. Glaciers  descend from the permanently snow-clad top of the range. The range  divides the island climatically: the forested western slopes and narrow  coastal plain are much wetter than the eastern slopes and wide Canter�  bury Plains. Much of the southwest area was designated a UNESCO  World Heritage site in 1990.</p><p>Southern Christian Leadership Conference (SCLC) U.S. non�  sectarian agency founded by Martin Luther King, Jr., and others in 1957  to assist local organizations working for equal rights for African Ameri�  cans. Operating primarily in the South, it conducted leadership-training  programs, citizen-education projects, and voter-registration drives. It  played a major role in the historic March on Washington in 1963 and in  the campaigns to urge passage of the Civil Rights Act of 1964 and the  Voting Rights Act of 1965. After King�s assassination in 1968, Ralph Aber�  nathy became president. In the early 1970s the SCLC was weakened by  several schisms, including the departure of Jesse Jackson, who founded  Operation PUSH in Chicago.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1792 I Southey &#x25BA; Soyinka</p><p>Southey Vsau-the, 'sa-theV Robert (b. Aug. 12,1774, Bristol, Glouces�  tershire, Eng.�d. March 21, 1843, Keswick, Cumberland) English poet  and prose writer. In youth Southey ardently embraced the ideals of the  French Revolution, as did Samuel Taylor Coleridge, with whom he was  associated from 1794. Like Coleridge, he gradually became more con�  servative. About 1799 he devoted himself to writing; later he was obliged  to produce unremittingly to support both his and Coleridge�s family. In  1813 he was appointed poet laureate. His poetry is now little read, but his  prose style is masterly in its ease and clarity, as seen in such works as Life  of Nelson (1813), Life of Wesley (1820), and The Doctor (1834^47), a  fantastic, rambling miscellany.</p><p>Southwest Indians Any of the American Indians who inhabit what is  now the southwestern U.S. Though highly diversified culturally and lin�  guistically, the Southwest Indians divide roughly into four groupings: the  Yuman tribes, the Pima and Papago, the Pueblo, and the Navajo and Apache.</p><p>Soutine \sii-'ten\, Chaim (b. 1893/94?, Smilovichi, near Minsk, Rus�  sian Empire�d. Aug. 9, 1943, Paris, Fr.) Russian-born French painter.  After studying art in Vilnius, he went to Paris in 1913 to study at the  Ecole des Beaux-Arts. An art dealer enabled him to paint for three years  in southern France, where his mature style emerged. His highly individu�  alistic style, stimulated by Expressionism, is characterized by thick impasto,  agitated brushwork, convulsive compositional rhythms, and disturbing  psychological content. Best known are his studies of choirboys and cooks,  his series of page boys, and his paintings of hung poultry and beef car�  casses, which vividly convey the colour and luminosity of putrescence.</p><p>Souvanna Phouma Vsu-'va-na-'pii-maV (b. Oct. 7, 1901, Luang Pra-  bang, Laos�d. Jan. 10, 1984, Vientiane) Premier of Laos (1951-54, 1960,  1962, 1974-75). Nephew of King Sisavangvong of Laos, Souvanna did  not support his uncle�s decision to welcome back French rule after the  end of World War II. With his half brother Souphanouvong, he joined the  Free Laos movement and went into exile when the French reoccupied  Laos. In 1949, when the French began to concede authority, he returned,  and in 1951 he began his first term as premier. Civil war broke out  between the communist Pathet Lao and rightist members of the govern�  ment; Souvanna served as premier sporadically during that period. He  tried to maintain Laotian neutrality during the Vietnam War but came to  depend on U.S. military aid; Laos stabilized after the U.S. withdrawal  from Vietnam. Souvanna remained an adviser to the government until his  death.</p><p>Sovereign Council Administrative body that governed the colony of  New France in Canada (1663-1702). The council consisted of the gover�  nor and the bishop (who together appointed the other members), five  councillors, an attorney general, and a clerk. The council named judges  and minor officials, controlled public funds and commerce with France,  and regulated the fur trade with the Indians. Decisions were subject to the  governor�s veto. In 1675 a royal edict increased the number of council�  lors to seven, with vacancies to be filled by the king. From 1685 the  intendant, a French administrative official, assumed many of the council�s  duties. The council was renamed the Superior Council in 1702.</p><p>sovereignty In political theory, the ultimate authority in the decision�  making process of the state and in the maintenance of order. In 16th-  century France Jean Bodin used the concept of sovereignty to bolster the  power of the king over his feudal lords, heralding the transition from feu�  dalism to nationalism. By the end of the 18th century, the concept of the  social contract led to the idea of popular sovereignty, or sovereignty of  the people, through an organized government. The Hague Conventions,  the Geneva Conventions, and the United Nations all have restricted the  actions of sovereign countries in the international arena, as has interna�  tional LAW.</p><p>soviet Council that constituted the primary unit of government in the  Soviet Union. The first soviet was formed in St. Petersburg during the  Russian Revolution of 1 905 to coordinate revolutionary activities, but it  was suppressed. Socialist leaders formed the second soviet shortly before  the abdication of Nicholas II, with one deputy for every 1,000 workers  and every military company. After the Russian Revolution of 1917, the  Bolsheviks gradually gained a dominant position in soviets across the land.  In 1918 a new constitution established soviets as the formal unit of local  and regional government. The 1936 constitution created a directly elected  bicameral Supreme Soviet, but the single candidate per district was cho�  sen by the Communist Party of the Soviet Union.</p><p>Soviet law Law that developed in the Soviet Union after the Russian  Revolution of 1917 and that, after World War II, was assimilated by other  communist states. Legislative enactments, including the constitution of  the U.S.S.R., were the principal sources of law in the Soviet legal sys�  tem; these were then elaborated in codes of statutes by each union repub�  lic. No distinction between public and private law existed; all legal matters  involved the state. Law was generally thought of as a force for restruc�  turing society and advancing the nation toward communism. Also known  as socialist law, it was based on the writings of Karl Marx and Friedrich  Engels. In addition to criminal and civil offenses, �administrative  offenses� constituted a large proportion of cases and were dealt with out�  side the court system.</p><p>Soviet Union See Union of Soviet Socialist Republics</p><p>sow \'sau\ bug or wood louse Any of certain terrestrial crustaceans  of the order Isopoda, especially  members of the genus Oniscus.</p><p>Native to Europe, they have been  introduced into North America.

It adjoins Johannesburg on the southwest, and  its name is an acronym derived from South-Western Townships. It was  originally set aside by the South African white government for residence  by blacks. The townships constituting Soweto grew out of shantytowns  that arose with the arrival of black labourers from rural areas, especially  between the World Wars. There is little industrial development; most of  Soweto�s residents commute to Johannesburg for employment. It is the  country�s largest black urban complex, and its residents were active in the  protests that helped bring an end to apartheid by 1991.</p><p>Soya Strait See La Perouse Strait</p><p>soybean Annual legume (Glycine max, or G. soja ) of the pea family  (see legume) and its edible seed. The  soybean plant has an erect, branch�  ing stem, white to purple flowers,  and one to four seeds per pod. It was  probably derived from a wild plant  of East Asia, where it has been cul�  tivated for some 5,000 years. Intro�  duced into the U.S. in 1804, it began  to be farmed widely as a livestock  feed in the 1930s, and the U.S. is  now the world�s foremost soybean  producer. Economically the world�s  most important bean, the soybean  provides vegetable protein for mil�  lions of people and ingredients for  hundreds of chemical products,  including paints, adhesives, fertiliz�  ers, insect sprays, and fire-extinguisher fluids. Because soybeans contain  no starch, they are a good source of protein for diabetics. Processed for  food, soybean oil is made into margarine, shortening, and vegetarian  cheeses and meats. Soybean meal serves as a high-protein meat substi�  tute in many food products, including baby foods. Other food products  include soybean milk, tofu, salad sprouts, and soy sauce.</p><p>Soyinka Vsho-'yiq-kaV Wole in full Akinwande Oluwole So�  yinka (b.

The first version accommodated three  persons but was later modified for a crew of two to make room for addi�  tional life-support equipment. Soyuz T, introduced in 1979, restored the  third crew seat. Soyuz TM, an upgrade featuring a variety of new sys�  tems, made its first manned flight in 1987 when it carried Mir�s second  crew to the then-embryonic station. The Soyuz TMA debuted in 2002 with  a manned flight to the ISS; its design incorporated changes to meet cer�  tain NASA requirements as an ISS �lifeboat,� including eased height and  weight restrictions for crew members.</p><p>spa Spring or resort with thermal or mineral water for drinking and  bathing. The word derives from a Belgian town whose springs reputedly  had curative powers. Mineral springs usually contain various salts, trace  minerals, and gases; many are naturally carbonated. Most thermal springs  (see hot spring) also contain minerals. Warm-water bathing aids relaxation  (see hydrotherapy), and high salt or sulfur content helps some skin con�  ditions. Drinking mineral water is believed to aid digestion, and waters  with specific minerals are used for particular conditions.</p><p>Spaak \'spak\, Paul-Henri (b.

For most of the period from 1936 to 1966 he served as  Belgium�s foreign minister, and he twice served as its premier (1938-39,  1947-50). An advocate of European cooperation, he helped form the  Benelux Economic Union (1944) and helped draft the UN charter, and in  1946 he served as the UN General Assembly�s first president. He signed  the Brussels Treaty, helped form NATO, and served as NATO�s secretary-  general (1957-61). He also helped create the European Economic Commu�  nity and the European Atomic Energy Community.</p><p>Spaatz YspatsV Carl (Andrews) known as Tooey Spaatz (b.

During  World War II he commanded the U.S. Strategic Air Forces in Europe  (1944), directing the strategic bombing of Germany. In 1945, though per�  sonally opposed to using atomic bombs against cities, he directed the  atomic bombing of Japan under orders of Pres. Harry Truman. In 1947 he  became the first chief of staff of the independent Air Force.</p><p>space contraction See Lorentz-FitzGerald contraction</p><p>space exploration Investigation of the universe beyond Earth�s  atmosphere by means of manned and unmanned spacecraft. Study of the  use of rockets for spaceflight began early in the 20th century. Germany�s  research on rocket propulsion in the 1930s led to development of the V-2  missile. After World War II, the U.S. and the Soviet Union, with the aid of  relocated German scientists, competed in the �space race,� making sub�  stantial progress in high-altitude rocket technology (see staged rocket).  Both launched their first satellites (see Sputnik; Explorer) in the late 1950s  (followed by other satellites and unmanned lunar probes) and their first  manned space vehicles (see Vostok; Mercury) in 1961. A succession of  longer and more complex manned space missions followed, most nota�</p><p>bly the U.S. Apollo program, including the first manned lunar landing in  1969, and the Soviet Soyuz and Salyut missions. Beginning in the 1960s,  U.S. and Soviet scientists also launched unmanned deep-space probes for  studies of the planets and other solar system objects (see Pioneer; Venera;  Viking; Voyager; Galileo), and Earth-orbiting astronomical observatories  (see, for example, Hubble Space Telescope), which permitted observation of  cosmic objects from above the filtering and distorting effects of Earth�s  atmosphere. In the 1970s and �80s the Soviet Union concentrated on the  development of space stations for scientific research and military recon�  naissance (see Salyut; Mir). After the dissolution of the Soviet Union in  1991, Russia continued its space program, but on a reduced basis owing  to economic constraints. In 1973 the U.S. launched its own space station  (see Skylab), and since the mid 1970s it has devoted much of its manned  space efforts to the space shuttle program and, more recently, to develop�  ing the International Space Station in collaboration with Russia and other  countries.</p><p>space frame Three-dimensional truss based on the rigidity of the tri�  angle and composed of linear elements subject only to compression or  tension. Its simplest spatial unit is a tetrahedron having four joints and six  members. A space frame forms a very strong, thick, flexible structural  fabric that can be used horizontally or bent to a variety of shapes. The  beauty of its open latticework web of lightweight tubular diagonals is only  surpassed by its structural purity. R. Buckminster Fuller used this technol�  ogy for some of his Dymaxion projects; in his Union Tank Car warehouse.  Baton Rouge, La. (1958), a space frame reinforces an enormous geode�  sic dome.</p><p>space shuttle formally Space Transportation System (STS)</p><p>Partially reusable rocket-launched vehicle developed by NASA to go into  Earth orbit, transport people and cargo between Earth and orbiting space�  craft, and glide to a runway landing on Earth. The first flight of a space  shuttle into orbit took place in 1981. The shuttle consists of a winged  orbiter that carries crew and cargo; an expendable external tank of liquid  fuel and oxidizer for the orbiter�s three main rocket engines; and two  large, reusable solid-propellant booster rockets. The orbiter lifts off ver�  tically like an expendable launch vehicle but makes an unpowered descent  similar to a glider. Each orbiter was designed to be reused up to 100 times.  For manipulating cargo and other materials outside the orbiter, astronauts  use a remotely controlled robot arm or exit the orbiter wearing space-  suits. On some missions, the shuttle carries a European-built pressurized  research facility called Spacelab in its cargo bay. Between 1981 and 1985,  four shuttle orbiters were put into service: Columbia (the first in orbit),  Challenger , Discovery , and Atlantis. Challenger exploded in 1986 during  launch, killing all seven astronauts aboard; it was replaced in 1992 by  Endeavour. From 1995 to 1998, NASA conducted shuttle missions to the  Russian space station Mir to prepare for the construction of the Interna�  tional Space Station (ISS). Beginning in 1998, the shuttle was used exten�  sively to ferry components, supplies, and crews to the ISS. In 2003  Columbia disintegrated while returning from a space mission, claiming  the lives of its seven-person crew.</p><p>space station Manned artificial structure designed to revolve in a fixed  orbit as a long-term base for astronomical observations, study of Earth�s  resources and environment, military reconnaissance, and investigations of  materials and biological systems in weightless conditions. As of 2001,  nine space stations have been placed in a low Earth orbit and occupied  for varying lengths of time. The Soviet Union orbited the world�s first  space station, Salyut 1, designed for scientific studies, in 1971. From 1974  to 1982 five more Salyut stations�two outfitted for military  reconnaissance�were successfully placed in orbit and occupied. In 1986  the U.S.S.R. launched the core module of Mir, a scientific station that was  expanded with five additional modules over the next decade. The U.S.  orbited its first space station in 1973; called Skylab, it was equipped as a  solar observatory and medical laboratory. In 1998 the U.S. and Russia  began the in-orbit construction of the International Space Station (ISS), a  complex of laboratory and habitat modules that would ultimately involve  contributions from at least 16 countries. In 2000 the ISS received its first  resident crew.

He also showed that space-time is curved, which  allowed him to account for gravitation in his general theory of relativity.</p><p>spacecraft Vehicle designed to operate, with or without a crew, in a  controlled flight pattern above Earth�s lower atmosphere. Since stream�  lining is not needed in the high vacuum of this environment, a space�  craft�s shape is designed according to its mission (see space exploration).  Most spacecraft are not self-propelled; they are accelerated to the neces�  sary high velocity by staged rockets, which are jettisoned when their fuel  is used up. A major exception, the space shuttle orbiter, uses three onboard  liquid-fuel main engines supplied by a disposable external tank and a pair  of solid-fuel boosters to reach space. The spacecraft goes into an orbit  around Earth or, if given enough velocity, it continues toward another  destination in space. The craft may have its own small rocket engines for  orienting and maneuvering. For internal power, Earth-orbiting spacecraft  use solar cells and storage batteries, fuel cells, or a combination, whereas  craft designed for deep-space missions usually carry thermoelectric gen�  erators heated by a radioactive element. The enormous complexity of  design, particularly of manned spacecraft with their millions of compo�  nents, requires a high degree of miniaturization and reliability.

Spain has a developed market economy based on services, light and heavy  industries, and agriculture. Mineral resources include iron ore, mercury,  and coal. Agricultural products include grains and livestock. Spain is one of  the world�s major producers of wine and olive oil. Tourism is also a major  industry, especially along the southern Costa del Sol. Spain is a constitu�  tional monarchy with two legislative houses; the chief of state is the king,  and the head of government is the prime minister.</p><p>Remains of Stone Age populations dating back some 35,000 years have  been found throughout Spain. Celtic peoples arrived in the 9th century bc,  followed by the Romans, who dominated Spain from c. 200 bc until the  Visigoth invasion in the early 5th century ad. In the early 8th century most  of the peninsula fell to Muslims (Moors) from North Africa, and it  remained under their control until it was gradually reconquered by the  Christian kingdoms of Castile, Aragon, and Portugal. Spain was reunited in  1479 following the marriage of Ferdinand II (of Aragon) and Isabella I (of  Castile). The last Muslim kingdom, Granada, was reconquered in 1492,  and about this time Spain established a colonial empire in the Americas. In  1516 the throne passed to the Habsburgs, whose rule ended in 1700 when  Philip V became the first Bourbon king of Spain. His ascendancy caused the  War of the Spanish Succession, which resulted in the loss of numerous Euro�  pean possessions and sparked revolution within most of Spain�s American  colonies. Spain lost its remaining overseas possessions to the U.S. in the  Spanish-American War (1898).

When arches  adjoin, the entire area between their crowns and springing line is a span�  drel. If filled in, as is ordinarily the case, the result is a spandrel wall; in  medieval architecture this was usually ornamented. In buildings of more  than one story, the spandrel is the area between the sill of a window and</p><p>the head of the window below it. In steel or reinforced-concrete struc�  tures, a deep spandrel beam may span across this area. The triangular area  of space beneath a stair is also known as a spandrel.</p><p>spaniel Any of several breeds of dogs used to flush game.

The larger breeds are  called springers, the smaller ones  cockers. Breeds include the cocker  spaniel, a round-headed, floppy�  eared dog; the English and Welsh  springer spaniels; the American  water spaniel, a curly-coated, dark  brown dog; the Brittany spaniel, a  short-tailed French dog and the only  spaniel that points; the Clumber  spaniel, a low-slung, long-bodied dog; the Irish water spaniel, a water  retriever; the Japanese spaniel; and the English toy spaniel.</p><p>Spanish-American War (1898) Conflict between the U.S. and Spain  that ended Spanish colonial rule in the New World. The war originated  in Cuba�s struggle for independence. The newspapers of William Randolph  Hearst fanned U.S. sympathy for the rebels, which increased after the  unexplained destruction of the U.S. warship Maine on Feb. 15, 1898.  Congress passed resolutions declaring Cuba�s right to independence and  demanding that Spain withdraw its armed forces. Spain declared war on  the U.S. on April 24. Commo. George Dewey led the naval squadron that  defeated the Spanish fleet in the Philippines (see Battle of Manila Bay) on  May 1, and Gen. William Shafter led regular troops and volunteers (includ�  ing future U.S. president Theodore Roosevelt and his Rough Riders) in the  destruction of Spain�s Caribbean Sea fleet near Santiago, Cuba (July 17).  In the Treaty of Paris (December 10), Spain renounced all claim to Cuba  and ceded Guam, Puerto Rico, and the Philippines to the U.S., marking  the U.S.�s emergence as a world power.</p><p>Spanish Armada See Spanish Armada</p><p>Spanish Civil War (1936-39) Military revolt against the government  of Spain. After the 1936 elections produced a Popular Front government  supported mainly by left-wing parties, a military uprising began in gar�  rison towns throughout Spain, led by the rebel Nationalists and supported  by conservative elements in the clergy, military, and landowners as well  as the fascist Falange. The ruling Republican government, led by the  socialist premiers Francisco Largo Caballero and Juan Negrfn (1894-  1956) and the liberal president Manuel Azana y Diaz, was supported by  workers and many in the educated middle class as well as militant anar�  chists and communists. Government forces put down the uprising in most  regions except parts of northwestern and southwestern Spain, where the  Nationalists held control and named Francisco Franco head of state. Both  sides repressed opposition; together, they executed or assassinated more  than 50,000 suspected enemies to their respective causes. Seeking aid  from abroad, the Nationalists received troops, tanks, and planes from Nazi  Germany and Italy, which used Spain as a testing ground for new meth�  ods of tank and air warfare. The Republicans (also called loyalists) were  sent materiel mainly by the Soviet Union, and the volunteer International  Brigades also joined the Republicans. The two sides fought fierce and  bloody skirmishes in a war of attrition. The Nationalist side gradually  gained territory and by April 1938 succeeded in splitting Spain from east  to west, causing 250,000 Republican forces to flee into France. In March  1939 the remaining Republican forces surrendered, and Madrid, beset by  civil strife between communists and anticommunists, fell to the Nation�  alists on March 28. About 500,000 people died in the war, and all Span�  iards were deeply scarred by the trauma. The war�s end brought a period  of dictatorship that lasted until the mid-1970s.</p><p>Spanish Guinea See Equatorial Guinea</p><p>Spanish Influenza Epidemic See Influenza Epidemic of 1918-19</p><p>Spanish Inquisition See Inquisition</p><p>Spanish language Romance language spoken in Spain and in large  parts of the New World.

It often hangs in large, beardlike, silvery-gray masses from trees  and other plants and even on telephone poles, but it is not parasitic or  structurally intertwined with its host. It takes in carbon dioxide and rain�  water or dew for photosynthesis through tiny, hairlike scales that cover its  threadlike leaves and long, threadlike stems. It absorbs nutrients from dust  and solvents in rainwater, or from decaying organic matter around its  aerial roots. Stalkless yellow flowers appear rarely. Spanish moss is some�  times used as a filler in packing boxes and upholstery, and around potted  plants or floral arrangements.</p><p>Spanish Netherlands Spanish-held provinces in the southern Low  Countries (roughly corresponding to modem Belgium and Luxembourg).  In 1578 the diplomat Alessandro Farnese was sent to represent Spain in  the Netherlands, and by 1585 he had reestablished Spanish control over  the southern provinces, ending the union with the northern provinces that  followed the Pacification of Ghent. In the 17th century the region saw a  resurgence of economic and intellectual growth. As a buffer between Prot�  estant and Catholic states, the region was the scene of constant warfare;  areas were ceded to the Dutch Republic (1648) and France (1659). The  territory began to decline in the late 17th century. Spanish control was  lost after the War of the Spanish Succession, when the region passed to  Emperor Charles VI and became the Austrian Netherlands.</p><p>Spanish Sahara See Western Sahara</p><p>Spanish Succession, War of the (1701-14) Conflict arising from  the disputed succession to the throne of Spain after the death of the child�  less Charles II. The Habsburg Charles had named the Bourbon Philip, duke  d�Anjou, as his successor; when Philip took the Spanish throne as Philip  V, his grandfather Louis XIV invaded the Spanish Netherlands. The former  anti-French alliance from the War of the Grand Alliance was revived in  1701 by Britain, the Dutch Republic, and the Holy Roman emperor, who  had been promised parts of the Spanish empire by earlier treaties of par�  tition (1698, 1699). The English forces, led by the duke of Marlborough,  won a series of victories over France (1704-09), including the Battle of  Blenheim, which forced the French out of the Low Countries and Italy. The  imperial general, Eugene of Savoy, also won notable victories. In 1711  conflicts within the alliance led to its collapse, and peace negotiations  began in 1712. The war concluded with the Peace of Utrecht (1713), which  marked the rise of the power of Britain at the expense of both France and  Spain, and the Treaties of Rastatt and Baden (1714).</p><p>spanner See wrench</p><p>spark plug Device that fits into the cylinder head of an internal-  combustion engine and carries two electrodes separated by an air gap, across  which current from a high-tension ignition system discharges, creating a  spark and igniting the fuel.

Until 1957 she pub�  lished only poetry and criticism, including studies of Mary Shelley and the  Bronte sisters. Her fiction uses satire and wit to present serious themes,  often questions about good and evil. Memento Mori (1959) is her most  widely praised novel; the best-known is The Prime of Miss Jean Brodie</p><p>(1961; film, 1969).

Some species of  Fringillidae are common. The trim�  looking chipping and tree sparrows  have a reddish brown cap. The finely  streaked savanna and vesper spar�  rows inhabit grassy fields. The  heavily streaked song and fox spar�  rows are woodland dwellers. The  white-crowned and white-throated  sparrows are larger than most species  and have black-and-white crown stripes.</p><p>sparrow hawk Small hawk (usually genus Accipiter, family Accipi-  tridae), found in Africa, Europe, and Asia.

Of Dorian origin, it  was founded in the 9th century bc and developed as a strictly militaristic  society. In the 8th-5th centuries bc it subdued neighbouring Messenia.  From the 5th century bc the ruling class of Sparta devoted itself to war  and forged the most powerful army in Greece. After a long contest with  Athens in the Peloponnesian War (460�404 bc), it attained dominance over  all of Greece. Sparta�s power was broken by Thebes at the battle of Leuc-  tra in 371 bc. It lost its independence c. 192 bc when it was defeated by  and forced to join the Achaean League. It was made part of the Roman  province of Achaea in 146 bc. The Visigoths captured and destroyed the  city in ad 396. The ruins of its acropolis, agora, theatre, and temples  remain.</p><p>Spartacists Vspar-to-sostsV or Spartacus League Revolutionary  socialist group active in Germany (1914-18). It developed as an offshoot  of the Social Democratic Party and was officially founded in 1916 by Karl  Liebknecht, Rosa Luxemburg, and others who violently opposed Germany�s  role in World War I and called for a socialist revolution. The group encour�  aged demonstrations in December 1918 that led to the abortive Sparta�  cus Revolt in January 1919, after which the leaders were murdered by  members of the Freikorps. The league was then transformed into the Com�  munist Party of Germany.</p><p>Spartacus Vspar-to-kosV (d. 71 bc) Leader in the Gladiatorial War  against Rome (73-71). A Thracian, he served in the Roman army. He  became a bandit and was sold as a slave when caught. He escaped a  gladiatorial school, where he had plotted a revolt with other gladiators,  and set up camp on Mount Vesuvius, where he was joined by other run�  away slaves and some peasants. With a force of 90,000, he overran most  of southern Italy, defeating two consuls (72). He led his army north to the  Cisalpine Gaul, where he hoped to release them to find freedom, but they  refused to leave, preferring to continue the struggle. Returning south, he  attempted to invade Sicily but could not arrange the passage. The legions  of Marcus Licinius Crassus caught the slave army in Lucania and defeated  it; Spartacus fell in pitched battle. Pompey�s army intercepted and killed  many of those escaping north, and Crassus crucified 6,000 prisoners along  the Appian Way.</p><p>Spartan Alliance See Peloponnesian League</p><p>Spassky, Boris (Vasilyevich) (b.

Native to Europe and Asia, spearmint has been naturalized in  North America.</p><p>special education Education for students (such as the physically or  mentally disabled) with special needs. An early proponent of education  for the blind was Valentin Haiiy, who opened a school in Paris in 1784;  his efforts were followed by those of Louis Braille. Attempts to educate  deaf children predate Haiiy, but not until Friedrich Moritz Hill (1805-74)  developed an oral method of instruction did teaching to the deaf become  established. The development of standardized sign languages further  advanced instruction of the deaf. Scientific attempts to educate mentally  retarded children began with the efforts of Jean-Marc-Gaspard Itard  (1775-1838) to train a feral child known as the Wild Boy of Aveyron;  Itard�s work influenced such later theorists as Edouard Seguin (1812-80)  and Maria Montessori. Children with motor disabilities, once considered  subjects for special education, are usually integrated into the standard  classroom, often by means of wheelchairs and modified desks. Children  with learning disabilities and speech problems usually require specialized  techniques, often on an individual basis. For children with behavioral and  emotional disorders, special therapeutic and clinical services may be pro�  vided.</p><p>special effects Artificial visual or mechanical effects introduced into  a movie or television show. The earliest special effects were created  through special camera lenses or through tricks such as projecting a mov�  ing background behind the actors. Greater flexibility came with the devel�  opment of the optical printer, which made it possible to combine separate  pieces of film and replace part of an image, thus allowing for effects such  as characters flying through the air. Special effects have also been created  mechanically on the set through the use of devices such as wires, explo�  sives, and puppets and by building miniature models to simulate epic  scenes such as battles. The growing use of computer animation and  computer-generated imagery has produced increasingly elaborate and  realistic visual effects. Though each movie studio formerly had its own  special-effects department, effects are now created by private companies  such as George Lucas�s Industrial Light and Magic, formed to provide the  revolutionary effects seen in Star Wars (1977) and later movies.</p><p>Special Forces See Green Berets</p><p>Special Olympics International sports program for people with men�  tal retardation.

One of the fundamental processes of evolution, speci�  ation may occur in many ways. Investigators formerly found evidence for  speciation in the fossil record by tracing sequential changes in the struc�</p><p>ture and form of organisms. Genetic studies now show that such changes  do not always accompany speciation, since many apparently identical  groups are in fact reproductively isolated (i.e., they can no longer produce  viable offspring through interbreeding). Polyploidy (see ploidy) is a means  by which the beginnings of new species are created in just two or three  generations.</p><p>Specie Circular \'spe-,she\ (July 11, 1836) Executive order issued by  Pres. Andrew Jackson. It required payment for purchases of public lands  in gold or silver (specie means �money in coin�). The circular attempted  to reduce the amount of paper money in circulation and limit land specu�  lation. The result was deflationary and partly contributed to the economic  crisis called the Panic of 1837. The U.S. Congress repealed the circular  in 1838.</p><p>species Vspe-.shez, 'spe-,sez\ Subdivision of biological classification  composed of related organisms that share common characteristics and can  interbreed. Organisms are grouped into species according to their outer  similarities, but more important in classifying organisms that reproduce  sexually is their ability to interbreed successfully. To be members of the  same species, individuals must be able to mate and produce viable off�  spring. Because genetic variations originate in individuals which then pass  on their variations only within the species, it is at the species level that  evolution takes place (see speciation). The international system of binomial  nomenclature assigns new species a two-part name.</p><p>specific gravity or relative density Ratio of the density of a sub�  stance to that of a standard substance. For solids and liquids, the standard  substance is usually water at 39.2�F (4.0�C), which has a density of 1.00  kg/liter. Gases are usually compared to dry air, which has a density of  1.29 g/liter at 32�F (0�C) and 1 atmosphere pressure. Because it is a ratio  of two quantities that have the same dimensions (mass per unit volume),  specific gravity has no dimension. For example, the specific gravity of  liquid mercury is 13.6, because its actual density is 13.6 kg/liter, 13.6  times that of water.</p><p>specific heat Ratio of the quantity of heat required to raise the tem�  perature of a body one degree to that required to raise the temperature of  an equal mass of water one degree. The term is also used to mean the  amount of heat, in calories, required to raise the temperature of one gram  of a substance by one Celsius degree.</p><p>speckled trout See brook trout</p><p>spectacled bear or Andean bear Only South American species of  bear (Tremarctos ornatus, family Ursidae), found in mountain forests,  especially in the Andes.

It succeeded The Tatler, launched by  Steele in 1709. Aiming to �enliven morality with wit, and to temper wit  with morality,� The Spectator presented a fictional club whose imaginary  members expressed the writers� ideas about society. It made serious dis�  cussion of letters and politics a normal pastime of the leisured class, set  the pattern and established the vogue for the periodical in the 18th cen�  tury, and helped create a receptive public for novelists.</p><p>spectrochemical analysis Any of a group of chemical analysis  methods that depend on measurement of the wavelength and intensity of  electromagnetic radiation. It is used chiefly to determine the arrangement  of atoms and electrons in molecules on the basis of the amounts of energy  absorbed during changes in their structure or motion. In more common  usage, it usually refers to ultraviolet (UV) and visible emission spectros�  copy or to UV, visible, and infrared (IR) absorption spectrophotometry.</p><p>spectrometer Vspek-'tra-mo-toiA Device for detecting and analyzing  wavelengths of electromagnetic radiation, commonly used for molecular  spectroscopy; more broadly, any of various instruments in which an emis�  sion (as of electromagnetic radiation or particles) is spread out according  to some property (as energy or mass) into a spectrum and measurements are  made at points or regions along the spectrum. As used in traditional labo�  ratory analysis, a spectrometer includes a radiation source and detection  and analysis equipment. Emission spectrometers excite molecules of a</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1798 I spectrophotometry &#x25BA; spelling and grammar checkers</p><p>sample to higher energy states and analyze the radiation emitted when they  decay to the original energy state. Absorption spectrometers pass radia�  tion of known wavelength through a sample, varying the wavelengths to  produce a spectrum of results; the detector system reveals to what extent  each wavelength is absorbed. Fourier-transform spectrometers resemble  absorption spectrometers but use a broad band of radiation; a computer  analyzes the output to find the absorption spectrum. Different designs  allow study of various kinds of samples over many frequencies, at dif�  ferent temperatures or pressures, or in an electric or magnetic field. Mass  spectrometers (see mass spectrometry) spread out the atomic or molecular  components in a sample according to their masses and then detect the  sorted components.</p><p>spectrophotometry \,spek-tro-f3-'ta-m3-tre\ Branch of spectroscopy  dealing with measurement of radiant energy transmitted or reflected by a  body as a function of wavelength. The measurement is usually compared  to that transmitted or reflected by a system that serves as a standard. In  chemistry and physics, different types of spectrophotometers cover wide  ranges of the electromagnetic spectrum: ultraviolet (UV), visible light, infra�  red (IR), or microwave. UV spectrophotometry is particularly useful in  detecting and quantifying colourless substances in solution. IR spectro�  photometry is used mostly to study the molecular structures of complex  organic compounds. In astronomy and astrophysics, spectrophotometric  studies also include the X-ray and gamma ray ranges of the spectrum. See  also COLORIMETRY.</p><p>spectroscopy \spek-'tra-sko-pe\ Branch of analysis devoted to identi�  fying elements and compounds and elucidating atomic and molecular struc�  ture by measuring the radiant energy absorbed or emitted by a substance  at characteristic wavelengths of the electromagnetic spectrum (including</p><p>GAMMA RAY, X-RAY, ULTRAVIOLET, visible LIGHT, INFRARED, MICROWAVE, and RADIO-  frequency radiation) on excitation by an external energy source. The  instruments used are spectroscopes (for direct visual observation) or spec�  trographs (for recording spectra). Experiments involve a light source, a  prism or grating to form the spectrum, detectors (visual, photoelectric, radi�  ometric, or photographic) for observing or recording its details, devices  for measuring wavelengths and intensities, and interpretation of the mea�  sured quantities to identify chemicals or give clues to the structure of  atoms and molecules. Helium, cesium, and rubidium were discovered in the  mid-19th century by spectroscopy of the Sun�s spectrum. Specialized  techniques include Raman spectroscopy (see Chandrasekhara Venkata  Raman), nuclear magnetic resonance (NMR), nuclear quadrupole reso�  nance (NQR), dynamic reflectance spectroscopy, microwave and gamma  ray spectroscopy, and electron spin resonance (ESR). Spectroscopy now  also includes the study of particles (e.g., electrons, ions) that have been  sorted or otherwise differentiated into a spectrum as a function of some  property (such as energy or mass). See also mass spectrometry; spectrom�  eter; SPECTROPHOTOMETRY.</p><p>spectrum Arrangement according to wavelength (or frequency) of elec�  tromagnetic radiation. The visible, �rainbow� spectrum is the portion of  the electromagnetic spectrum that is visible as light to the human eye. Some  sources emit only certain wavelengths and produce an emission spectrum  of bright lines with dark spaces between. Such line spectra are character�  istic of the elements that emit the radiation. A band spectrum consists of  groups of wavelengths so close together that the lines appear to form a  continuous band. Atoms and molecules absorb certain wavelengths and  so remove them from a complete spectrum; the resulting absorption spec�  trum contains dark lines or bands at these wavelengths.</p><p>speech Human communication through audible language. Speech  sounds are made with air exhaled from the lungs, which passes between  the vocal cords in the larynx and out through the vocal tract (pharynx and  oral and nasal cavities). This airstream is shaped into different sounds by  the articulators, mainly the tongue, palate, and lips (see articulation). Artic�  ulatory phonetics describes each sound in terms of the position and action  of the articulators used to make it. Speech is also described in terms of  syntax, lexicon (inventory of words or morphemes), and phonology  (sounds).</p><p>speech, figure of See figure of speech</p><p>speech act theory Theory of meaning that holds that the meaning of  linguistic expressions can be explained in terms of the rules governing  their use in performing various speech acts (e.g., admonishing, asserting,  commanding, exclaiming, promising, questioning, requesting, warning).  In contrast to theories that maintain that linguistic expressions have mean�</p><p>ing in virtue of their contribution to the truth conditions of sentences  where they occur, it explains linguistic meaning in terms of the use of  words and sentences in the performance of speech acts. Some exponents  claim that the meaning of a word is nothing but its contribution to the  nature of the speech acts that can be performed by using it. Ludwig Wit�  tgenstein and J. L. Austin provided important stimuli for the theory�s devel�  opment.</p><p>speech recognition or voice recognition Ability of computer sys�  tems to accept speech input and act on it or transcribe it into written lan�  guage. Current research efforts are directed toward applications of  automatic speech recognition (ASR), where the goal is to transform the  content of speech into knowledge that forms the basis for linguistic or  cognitive tasks, such as translation into another language. Practical appli�  cations include DATABASE-query systems, information retrieval systems, and  speaker identification and verification systems, as in telebanking. Speech  recognition has promising applications in robotics, particularly develop�  ment of robots that can �hear.� See also pattern recognition.</p><p>speech synthesis Generation of speech by artificial means, usually  by computer. Production of sound to simulate human speech is referred to  as low-level synthesis. High-level synthesis deals with the conversion of  written text or symbols into an abstract representation of the desired  acoustic signal, suitable for driving a low-level synthesis system. Among  other applications, this technology provides speaking aid to the speech-  impaired and reading aid to the sight-impaired.</p><p>speech therapy Therapeutic treatment to correct defects in speaking.  Such defects may originate in the brain, the ear (see deafness), or any�  where along the vocal tract and may affect the voice, articulation, lan�  guage development, or ability to speak after language is learned. Therapy  begins with diagnosis of underlying physical, physiological, or emotional  dysfunction. It may involve training in breathing, use of the voice, and/or  speaking habits. Some abnormalities that cause speech disorders (e.g.,  cleft palate, stroke) can be corrected to various degrees before a speech  therapist�s work begins.

Two  types of track are used in international competition. The long track is a  400-m (about one-quarter mile) flattened oval (straight sides and curved  ends) on which two skaters race simultaneously. In long track the race is  against the clock rather than the opponent. The short track, a more recent  development, is a 111-m (364-ft) oval on which four to six skaters race  during each heat. Short track is a race to the finish line. Long-track speed  skating was included in the first Winter Olympics in 1924; short-track  skating was added in 1992.</p><p>Speer \'shpar\, Albert (b.

On the return trip  he left Burton and struck out northward alone. In July 1858 he reached a  great lake, which he named Lake Victoria, for the queen. His claim that  it was the source of the Nile was questioned, but on a second expedition  (1860-63) he found the Nile�s exit from the lake. Speke�s claim to have  found the Nile�s source was again challenged in England. He was killed  by his own gun while hunting on the very day he was to debate Burton  publicly.</p><p>spelling and grammar checkers Components of word-processing  programs for personal computers that identify apparent misspellings and  grammatical errors by reference to an incorporated dictionary and a list  of rules for proper usage.

He studied at Yale (B.A., 1966), Oxford (B.A./M.A., 1968), and Harvard  (Ph.D., 1972) and taught at Harvard and Stanford, serving as dean of the  latter�s business school from 1990 to 1999. He is known for refining the  theory of asymmetric information in the marketplace. His research dem�  onstrated that in certain situations those who are better informed can  improve their market return by transmitting information to those who  know less; for example, auto dealers can convey the superior quality of  their cars by offering warranties. For his work on �market signaling,�  Spence shared the 2001 Nobel Prize in Economic Sciences with George  A. Akerlof and Joseph E. Stiglitz.</p><p>Spencer, Herbert (b. April 27,1820, Derby, Derbyshire, Eng.�d. Dec.  8, 1903, Brighton, Sussex) English sociologist and philosopher, advocate  of the theory of social Darwinism. His System of Synthetic Philosophy, 9 vol.  (1855-96), held that the physical, organic, and social realms are intercon�  nected and develop according to identical evolutionary principles, a  scheme suggested by the evolution of biological species. This sociocultural  evolution amounted to, in Spencer�s phrase, �the survival of the fittest.� The  free market system, without interference by governments, would weed out  the weak and unfit. His controversial laissez-faire philosophy was praised  by social Darwinists such as William Graham Sumner and opposed by  sociologists such as Lester Frank Ward. Liked or loathed, Spencer was one  of the most discussed Victorian thinkers.</p><p>Spender, Sir Stephen (Harold) (b. Feb. 28, 1909, London,  Eng.�d. July 16, 1995, London) English poet and critic. While an under�  graduate at Oxford, Spender met the poets W.H. Auden and C. Day-Lewis.  In the 1930s they became identified with politically conscious, leftist �new  writing.� His poems, expressing a self-critical, compassionate personal�  ity, appeal� in volumes from Poems (1933) to Dolphins (1994). He was  better known for his perceptive criticism, as in The Destructive Element  (1935), The Making of a Poem  (1955), and The Struggle of the Mod�  ern (1963), and for his association  with the influential review Encoun�  ter (1953-67). He also wrote short  stories, essays, and autobiography.</p><p>Spengler \'shpeq-gbr\, Oswald  (b. May 29, 1880, Blankenburg,</p><p>Ger.�d. May 8, 1936, Munich) Ger�  man philosopher. A schoolmaster  before he turned to writing, Spengler  is remembered for his influential The  Decline of the West, 2 vol. (1918�</p><p>22), a study in the philosophy of his�  tory. He contended that civilizations  pass through a life cycle, blossoming  and decaying like natural organisms,  and that Western culture is irrevers�  ibly past its creative stage and  headed into eclipse. Though</p><p>acclaimed by a public disillusioned in the wake of World War I, his work  was criticized by both professional scholars and the Nazi Party, despite  some affinities with its dogma.</p><p>Spenser, Edmund (b. 1552/53, London, Eng.�d. Jan. 13, 1599, Lon�  don) English poet. Little is known for certain about his life before he  entered the University of Cambridge. His first important publication, The  Shepheardes Calender (1579), can be called the first work of the English  literary Renaissance. By 1580 he was apparently serving the Earl of  Leicester and was part of a literary circle led by Sir Philip Sidney. In 1580  he became secretary to the lord deputy of Ireland, where he spent much  of his remaining life; in 1588 or 1589 he took over a large property at  Kilcolman, near Cork. In 1590 he published the first part of the long alle�  gorical poem The Faerie Queene (first folio ed., 1609), an imaginative  vindication of Protestantism and Puritanism and a glorification of England  and Elizabeth I. The central poem of the Elizabethan period and one of  the greatest poems in English, it was composed in a revolutionary nine-  line stanzaic pattern, the �Spenserian stanza,� that was used by many later  poets. Of the 12 books he planned for the poem, he completed just over  half. Amoretti (1595), a sonnet sequence, and Epithalamion (1595), a  marriage ode, are among his other works. In the Irish uprising of 1598,  Kilcolman was burned; Spenser, probably in despair, died shortly after.</p><p>Speransky \spyi-'ran-ske\, Mikhail (Mikhaylovich), Count (b.</p><p>Jan. 12, 1772, Cherkutino, Russia�d.

He served as an assistant to Tsar Alexander I (1807-  12), but his proposed financial and administrative reforms angered the  nobles, who had him exiled (1812-16). He returned to government ser�  vice, serving as governor-general of Siberia (1819-21). A member of the  state council from 1821 under Nicholas I, he compiled the first complete  collection of Russian law (1830). He was given the title of count in 1839.</p><p>sperm or spermatozoon Vspor-.ma-to-'zo-onX Male reproductive  cell. In mammals, sperm are produced in the testes and travel through the  reproductive system. At fertilization, one sperm of the roughly 300 million  in an average ejaculation (see semen) fertilizes an egg (see ovary) to pro�  duce an offspring. At puberty, immature cells (spermatogonia) begin a  maturation process (spermatogenesis). A mature human sperm has a flat,  almond-shaped head, with a cap (acrosome) containing chemicals that  help it penetrate an ovum. It is essentially a cell nucleus, with 23 chro�  mosomes (including either the X or Y that determines the child�s sex). A  flagellum propels the sperm, which may live in a woman�s reproductive  tract for two to three days after sexual intercourse, to the egg. Sperm may  be frozen and stored for artificial insemination.</p><p>sperm whale or cachalot Vka-sho-.lat, 'ka-sho-.loN Thickset, blunt�  snouted toothed whale ( Physeter catodon, family Physeteridae) with  small, paddlelike flippers and rounded humps on the back. Sperm whales  have an enormous head, squarish in profile, and a narrow, underslung  lower jaw with large conical teeth that fit into sockets in the toothless  upper jaw when the mouth is closed. They are dark blue-gray or brown�  ish. (Herman Melville�s Moby-Dick was presumably an albino.) The male  grows to 60 ft (18 m). Herds of 15-20 live in temperate and tropical waters  worldwide. They commonly dive to 1,200 ft (350 m), feeding primarily  on cephalopods. The whales have been hunted for their spermaceti (a  waxy substance in the snout, used in ointments and cosmetics) and for  ambergris. The pygmy sperm whale (genus Kogia) is a black dolphinlike  whale, about 13 ft (4 m) long, of the Northern Hemisphere that lacks  commercial value.</p><p>spermatophyte See seed plant</p><p>Sperry, Elmer (Ambrose) (b. Oct. 12,1860, Cortland, N.Y., U.S.�d.  June 16, 1930, Brooklyn, N.Y.) U.S. inventor and industrialist. He opened  his own factory in Chicago at the age of 20 to make dynamos and arc  lamps. He designed an electrical industrial locomotive and motor trans�  mission machinery for streetcars and later made electric automobiles pow�  ered by his patented battery. He invented processes for salvaging tin and  producing white lead and for manufacturing fuse wire. His greatest inven�  tions sprang from the gyroscope (until then considered only a toy), which,  once properly aligned, always points to true north. His gyrocompass was  first installed on the battleship Delaware in 1911. He extended the gyro  principle to guidance of torpedoes, to gyropilots for the steering of ships  and for stabilizing airplanes, and finally to a ship stabilizer. In all, he  founded eight manufacturing companies and took out more than 400  patents.</p><p>&#x2713;</p><p>Spengler, pencil drawing by K.

The components  and properties of a sphere are analo�  gous to those of a circle. A diameter is any line segment connecting two  points of a sphere and passing through its centre. The circumference is  the length of any great circle, the intersection of the sphere with any plane  passing through its centre. A meridian is any great circle passing through  a point designated a pole. A geodesic, the shortest distance between any  two points on a sphere, is an arc of the great circle through the two points.  The formula for determining a sphere�s surface area is 47tr 2 ; its volume  is determined by ( 4 /3)kP. The study of spheres is basic to terrestrial geog�  raphy and is one of the principal areas of Euclidean geometry and elliptic  GEOMETRY.</p><p>sphere, celestial See celestial sphere</p><p>sphere of influence In international politics, a state�s claim to exclu�  sive or predominant control over a foreign area or territory. Beginning in  the late 1880s, European colonial powers undertook legal agreements  consisting of promises not to interfere with each other�s actions in mutu�  ally recognized spheres of influence in Africa and Asia. After colonial  expansion ceased, geopolitical rather than legal claims to spheres of influ�  ence became common, examples being the U.S. claim to dominance in  the Western Hemisphere under the much-earlier Monroe Doctrine and the  Soviet Union�s expansion of its sphere of influence to eastern Europe fol�  lowing World War II. See also Iron Curtain.</p><p>spherical coordinate system In geometry, a coordinate system in  which any point in three-dimensional space is specified by its angle with  respect to a polar axis and angle of rotation with respect to a prime merid�  ian on a sphere of a given radius. In spherical coordinates a point is speci�  fied by the triplet (r, 0, (p), where r is the point�s distance from the origin  (the radius), 0 is the angle of rotation from the initial meridian plane, and  cp is the angle from the polar axis (analogous to a ray from the origin  through the North Pole).</p><p>sphinx Mythological creature with a lion�s body and a human�s head. It  figures prominently in Egyptian and Greek art and legend. The winged  sphinx of Thebes was said to have terrorized people by demanding the  answer to a riddle taught to her by the Muses �What is it that has one voice  and yet becomes successively four-footed, then two-footed, then three�  footed?�and devoured every person who answered incorrectly. When  Oedipus correctly answered �man��who crawls on all fours in infancy,  walks on two feet when grown, and leans on a staff in old age�the sphinx  killed herself. The earliest and most famous example in art is the Great  Sphinx at Giza in Egypt, built c. 2500 bc. The sphinx appeared in the Greek  world c. 1600 bc and in Mesopotamia c. 1500 bc.

Sphynx cats must be bathed regularly to keep the skin free of the  oils that the coat on a normal cat absorbs, and the very large ears must  be cleaned regularly to rid them of dust and dirt and prevent wax buildup.</p><p>spice and herb Dried parts of various plants cultivated for their aro�  matic, savory, medicinal, or otherwise desirable properties. Spices are the  fragrant or pungent products of such tropical or subtropical species as  cardamom, cinnamon, clove, ginger, and pepper; spice seeds include ANISE,  caraway, cumin, fennel, poppy, and sesame. Herbs are the fragrant leaves of  such plants as basil, marjoram, mint, rosemary, and thyme. The most notable  uses of spices and herbs in very early times were in medicine, in the mak�  ing of holy oils and unguents, and as aphrodisiacs; they were also used  to flavour food and beverages and to inhibit or hide food spoilage. Trade  in spices has played a major role in human history. Important early trade  routes, including those between Asia and the Middle East and between  Europe and Asia, were initially forged to obtain exotic spices and herbs.  The 15th-century voyages of discovery were launched largely as a result  of the spice trade, and in the 17th century Portugal and the British, Dutch,  and French East India companies battled furiously for dominance (see  British East India Co.; Dutch East India Co.; French East India Co.).</p><p>spicebush Deciduous, dense shrub (Lindera benzoin, or Benzoin aes-  tivale) of the iaurel family, native to  eastern North America. Found most  often in damp woods, it grows 5-20  ft (1.5-6 m) tall. The shiny, oblong  leaves (3-5 in., or 8-13 cm, long) are  wedge-shaped near the base. Small,  yellow flowers crowded in small,  nearly stalkless clusters are followed  by fleshy red fruit with a stony cov�  ering around the seed. Tea is some�  times brewed from young twigs,  leaves, and fruit.</p><p>spider Any of some 34,000 preda�  tory arachnid species, mostly terres�  trial, in the order Araneida, abundant  worldwide except in Antarctica. Spi�  ders have two main body parts, eight legs, two pincerlike venomous  appendages, and three pairs of spinnerets. Species range in length from  0.5 to about 90 mm (0.02 to 3.5 inches). The venom of a few species  (e.g., brown recluse) is harmful to humans. Most species catch insect prey  in a web of silk extruded from the spinnerets. Spiders change little dur�  ing growth, except in size. Species are classified largely on the basis of  the number and arrangement of eyes and the type of web.

They use a mucuslike  mouth secretion to fasten algae,  sponges, and other organisms to the  hairs, spines, and knobby projections  covering the body. Most species are  scavengers, especially of carrion.</p><p>Their size varies greatly. The body of  the European long-beaked spider  crab (Macropodia rostrata ) is less  than 0.5 in.

Adult spider mites are tiny, about 0.02 in. (0.5 mm) long, and often  red. They spin a loose silk webbing on infested plants. A heavy infesta�  tion can cause complete defoliation. Because of their increasing resistance  to pesticides, they are difficult to control. One effective control is the use  of another, predatory, mite species.</p><p>spider monkey Any of four species (family Cebidae) of diurnal, arbo�  real New World monkeys found from Mexico to Brazil. Long-limbed and  somewhat potbellied, they are 14-26 in. (35-66 cm) long and have thumb�  less hands and a heavily furred, prehensile 24-36-in. (60-92-cm) tail. The  coat is gray, reddish, brown, or black. They swing through branches, using  their tails and hands, or leap or drop spread-eagled from tree to tree. They  eat fruit, nuts, flowers, and buds. They are used in laboratory studies of  malaria, to which they are susceptible. Though sometimes kept as pets,  adults are likely to throw tantrums and may be dangerous.</p><p>spider plant African plant of genus Chlorophytum (lily family).

As a director of television movies, he  made the thriller Duel (1971), and in 1974 he directed the feature film  The Sugarland Express. His shark-attack thriller Jaws (1975) became one  of the highest-grossing movies ever, and he went on to direct huge suc�  cesses such as Close Encounters of the Third Kind (1977), Raiders of the  Lost Ark (1981), and E.T.�the Extraterrestrial (1982). He received Acad�  emy Awards for directing Schindler�s List (1993), which tells the story of  a group of Polish Jews who avoided Nazi extermination camps through  the heroic actions of a German industrialist, and Saving Private Ryan  (1998), which followed American soldiers in the days after the Normandy</p><p>invasion of 1944. His other movies include The Color Purple (1985),  Empire of the Sun (1987), Jurassic Park (1993), A.I.: Artificial Intelli�  gence (2001), and Minority Report (2002).

His first novel, I, The Jury (1947), introduced the detective  Mike Hammer, who later appeared in works from My Gun Is Quick ( 1950)  to Black Alley (1996). His other novels, all characterized by violence and  sexual licentiousness, include The Deep (1961), a series with the interna�  tional agent Tiger Mann beginning with Day of the Guns (1964), and The  Killing Man (1989). Spillane claimed to write solely for monetary gain  and flouted literary taste with recurring elements of sadism that disturbed  some readers, but the captivating vigour of his narrative and of his cen�  tral characters brought him popular success.</p><p>spin Amount of angular momentum associated with a subatomic particle or  nucleus. It is measured in multiples of h (h-bar), equal to Planck�s con�  stant divided by 27 t. Electrons, neutrons, and protons have a spin of Vi,  for example, while pions and helium nuclei have zero spin. The spin of a  complex nucleus is the vector sum of the orbital angular momentum and  intrinsic spins of the constituent nucleons. For nuclei of even mass num�  ber, the multiple is an integral; for those of odd mass number, it is a half�  integer.

Spinach requires cool weather and deep, rich, well-  limed soil to give quick growth and maximum leaf area; sowing seed  every two weeks from early spring to late summer provides a steady sup�  ply. A nutritious vegetable, spinach is rich in iron and vitamins A and C.</p><p>spinal cord In vertebrates, the body�s major nerve tract. In humans it  is about 18 in. (45 cm) long, running from the base of the brain through  the vertebral column. It is covered by the meninges and cushioned by cere�  brospinal fluid. It connects the peripheral nervous system (outside the brain  and spinal cord) to the brain. The spinal cord and the brain constitute the  central nervous system. Sensory impulses reach the brain via the spinal  cord, and impulses from the brain travel down the spinal cord to motor  neurons, which reach the body�s muscles and glands via the peripheral  nerves. The peripheral nerves are connected to the spinal cord via the spi�  nal nerves. In humans there are 31 pairs of spinal nerves containing both  sensory and motor fibres, which originate in the spinal cord and pass out  between the vertebrae. These nerves branch and relay motor impulses to  all parts of the body. Injury to the spinal cord may result in loss of com�  munication between the brain and outlying parts and cause paralysis, loss  of sensation, or weakness in the parts of the body served by areas below  the injured region. Because nerve cells and fibres are unable to regener�  ate themselves, the effects are usually permanent. See illustration on fol�  lowing page.</p><p>spindle and whorl or drop spindle Earliest device for spinning  fibres into thread or yarn. The spinster lets the spindle fall to draw out  the fibres while the whorl keeps it rotating to apply the necessary twist.

Also called magnesia spinel, its colour, due to various impu�  rities, ranges from blood-red to blue, green, brown, and colourless. Spinel  is found in basic igneous rocks, granite pegmatites, and contact metamor-  phic limestone deposits, often in association with corundum. Synthetic  spinel has been manufactured since the early 20th century for use as imi�  tation gem stones. Spinel may also refer more broadly to any of various  mineral oxides of magnesium, iron, zinc, or manganese in combination  with aluminum, chromium, or iron.</p><p>spinning In metalwork, a technique for making hollow metal utensils  and artifacts. Developed in the 19th century, the method can be used for  most metals. A metal disk is set on a lathe behind an appropriately shaped  metal or wooden chuck; while the lathe is rotating, the metal is pressed  onto the chuck with a tool. A typical modern spun object is the aluminum  saucepan. As in most metalworking techniques, the metal is periodically  softened by annealing, or heating, when it has become hardened by being  worked (see hardening).</p><p>Spider crab (Libinia)</p><p>WALTER DAWN</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1802 I spinning frame &#x25BA; spiritual</p><p>Section of a spinal cord.

The posterior horn contains  cell bodies from which fibres pass to the brain carrying impulses brought by sen�  sory fibres entering from the spinal nerves. Interneurons in the gray matter transmit  impulses within the cord. The white matter contains tracts of fibres that ascend to the  brain with sensory impulses and descend from the brain carrying motor impulses.

His philosophy represents a development of and reaction to  the thought of Rene Descartes; many of his most striking doctrines are  solutions to difficulties created by Cartesianism. He found three unsatis�  factory features in Cartesian metaphysics: the transcendence of God,  mind-body dualism, and the ascription of free will both to God and to  human beings. To Spinoza, those doctrines made the world unintelligible,  since it was impossible to explain the relation between God and the world  or between mind and body or to account for events occasioned by free  will. In his masterpiece, Ethics (1677), he constructed a monistic system  of metaphysics and presented it in a deductive manner on the model of  the Elements of Euclid. He was offered the chair of philosophy at the Uni�  versity of Heidelberg but declined it, seeking to preserve his indepen�  dence. His other major works are the Tractatus Theologico-Politicus  (1670) and the unfinished Tractatus Politicus.</p><p>spiny anteater See echidna</p><p>spire Steeply pointed termination to a tower or roof. In Gothic architec�  ture, the spire is a spectacular visual culmination of the building as well  as a symbol of heavenly aspiration. The church spire originated in the  12th century as a simple, four-sided pyramidal roof capping a tower.  Methods used to integrate an octagonal spire with a square tower below  include broaches (sloping triangular sections of masonry added to the  bottom of the four spire faces not coinciding with the tower sides), gabled  dormers added to spire faces, and steep pinnacles (vertical ornaments of  pyramidal or conical shape) added to tower comers. During the Deco�  rated period (14th century) in England, a slender needle spire set in from  the edge of the tower was popular; corner pinnacles and a low parapet  around the tower�s edge became customary. In the 20th century, archi�  tects tended to limit spires to rather elementary geometric shapes.</p><p>spirea \spI-'re-3\ Any of nearly 100 species of flowering shrubs in the  genus Spirea (rose family), native to  the northern temperate zone and  commonly cultivated for their pleas�  ing growth habit and attractive  flower clusters. The most commonly  grown, and possibly the most popu�  lar of all cultivated shrubs, is the  Vanhouttei spirea, also called bridal  wreath (a cross between S. can-  toniensis and S. trilobata ), which  grows up to 6 ft (2 m) tall and has  graceful arching branches that bear  numerous white flowers in spring.</p><p>Plants that resemble spirea are the  shrubby false spireas ( Sorbaria spe�  cies, also rose family) and the peren�  nial herbaceous spireas ( Astilbe  species, saxifrage family).</p><p>spirillum \spi-'ril-3m\ Any of the  spiral-shaped bacteria that make up  the genus Spirillum, which are  aquatic except for one species that causes a type of rat-bite fever in  humans. The term is used generally for any corkscrewlike species of bac�  teria (see spirochete). Spirilla are gram-negative (see gram stain) and move  by means of tufts of flagella at each end.</p><p>spirits See distilled liquor</p><p>spiritual In North American white and black folk music, an English-  language folk hymn. White spirituals derived variously, notably from the  �lining out� of psalms, dating from at least the mid-17th century. Where  congregations could not read, a leader intoned the psalm one line at a  time, alternating with the congregation�s singing of each line to a famil�  iar melody; the tune, sung slowly, was ornamented with passing notes.</p><p>Spiraea</p><p>E.R.

A second source was the singing of hymns set to  borrowed melodies, often secular folk tunes. Themes included going  home to the promised land and gaining ground against sin; typical refrains  were �Roll, Jordan� and �Glory Hallelujah.� The songs survive in oral  tradition in isolated areas and also in the form of shape-note singings. Afri�  can American spirituals developed in part from white rural folk hymnody  but differ greatly in voice quality, vocal effects, rhythm, and type of rhyth�  mic accompaniment. They were sung not only in worship but also as work  songs, and the text imagery often reflects concrete tasks. Like the white  gospel song, the modem African American gospel song derives from the  spiritual.</p><p>spiritualism Belief that the souls of the dead can make contact with  the living, usually through a medium or during abnormal mental states  such as trances. The basis of spiritualism is the conviction that spirit is  the essence of life and that it lives on after the body dies. A medium is a  person sensitive to vibrations from the spirit world, who may hold meet�  ings known as seances in order to seek messages from spirits. A �control�  is a spirit that gives messages to the human medium, who in turn gives  them to other people. Spirits are also thought to manifest themselves  through such means as rapping or levitating objects. Some spiritualists  claim powers of paranormal healing. Scientific study of spiritualist phe�  nomena has been the focus of the Society for Psychical Research, founded  in Britain in 1882. See also theosophy.</p><p>spirochete Vspl-r3-,ket\ Any of an order (Spirochaetales) of spiral�  shaped bacteria. Some are serious  pathogens for humans, causing such  diseases as syphilis, yaws, and relaps�  ing fever. Spirochetes are gram�  negative (see gram stain) and motile.</p><p>They are unique in that their flagella,  which number between two and  more than 200 per organism, are con�  tained within the cell. Most spiro�  chetes are found in a liquid  environment (e.g., mud and water,  blood and lymph). Several species  are borne by lice and ticks, which  transmit them to humans.</p><p>spirulina \,spir-u-'le-n3\ Any  cyanobacteria in the genus Spirulina.</p><p>A traditional food source in parts of Africa and Mexico, spirulina is an  exceptionally rich source of vitamins, minerals, and protein, and one of  the few nonanimal sources of vitamin B 12 . It is now being widely stud�  ied for its possible antiviral, anticancer, antibacterial, and antiparasitic  properties, and has been used for such medical conditions as allergies,  ulcers, anemia, heavy-metal poisoning, and radiation poisoning. It is also  used in weight-loss programs.</p><p>Spitfire or Supermarine Spitfire British fighter aircraft in World  War II. A low-wing monoplane first flown in 1936, it was adopted by the  RAF in 1938. At that time one of the war�s fastest single-seat fighters, it  was used effectively during the Battle of Britain. Later models allowed it  to serve as a fighter-bomber and a photoreconnaissance plane. The 1938  version had a top speed of about 360 mph (580 kph) and was armed with  eight .303-in. (7.7-mm) machine guns. The Spitfire XIV, one of the last  models of the war, had a ceiling of 40,000 ft (12,200 m) and a top speed  of 440 mph (710 kph). The RAF retired its last Spitfires in 1954.</p><p>Spitsbergen Main island within the Svalbard archipelago, Norway.  Spitsbergen lies 360 mi (580 km) north of the Norwegian mainland in the  Arctic Ocean. It was formerly known as West Spitsbergen. The terrain is  mountainous, and most of the island is covered with glaciers. It is also  deeply indented by fjords. Spitsbergen has extensive coal deposits.</p><p>Spitteler Vshpit-o-lorV Carl (b. April 24, 1845, Liestal, Switz.�d. Dec.  29, 1924, Lucerne) Swiss poet. He was a private tutor in Russia and Fin�  land before he wrote his first great poetic work, the mythical epic  Prometheus und Epimetheus (1881). His second great work was the epic  The Olympic Spring (1900-05), in which he found full scope for bold  invention and vividly expressive power. Late in life he rewrote his first  epic as Prometheus the Long-Suffering (1924). Though known for his  pessimistic yet heroic verse, he also wrote lyrical poems, stories, novels,  and essays. He received the Nobel Prize for Literature in 1919.</p><p>spittlebug or froghopper Any of some 2,000 species of hopping  insects (family Cercopidae, order Homoptera) with whitish nymphs that  use a special abdominal valve to aerate an anal fluid secretion. The result�  ing frothy spittle protects the nymphs from enemies and desiccation.  Adults are less than 0.6 in. (1.5 cm) long. The meadow spittlebug ( Philae-  nus leucophthalmus ), of Europe and North America, resembles a frog and  is a powerful leaper. It feeds extensively on clover and alfalfa, causing  severe stunting that can result in the loss of up to 50% of a crop. Some  African species occur in such enormous numbers that their spittle drips  from tree branches like rain.</p><p>spitz Any of several northern dogs, including the chow chow, Pomera�  nian, and Samoyed, characterized by a dense, long coat, erect pointed ears,  and a tail that curves over the back. In the U.S., the name is often given  to any small, white, long-haired dog; it is also used for the American  Eskimo dog. European breeds include the Finnish spitz, with a bright red�  dish brown coat, and the Lapland spitz, which has a white, brown, or  blackish coat.</p><p>Spitz, Mark (Andrew) (b. Feb. 10, 1950, Modesto, Calif., U.S.) U.S.  swimmer. He swam in college for Indiana University. At the 1968 Olym�  pic Games he won two gold medals in team relay races. In the 1972  Olympics he won four individual men�s events (setting world records in  all four) and three team events (one world record); Spitz�s feat of win�  ning seven gold medals in a single Olympic Games remains unmatched.</p><p>spleen Lymphoid organ, located in the left side of the abdomen behind  the stomach. The spleen is the primary filtering element for the blood,  and it is a storage site for red blood cells (erythrocytes) and platelets. It is  one of four places where reticuloendothelial cells are found (see reticu�  loendothelial system). Two types of tissue, red pulp and white pulp, are  intermixed. The white pulp is lymphoid tissue containing lymphocyte pro�  duction centres. The red pulp is a network of channels filled with blood  where most of the filtration occurs and is the major site of destruction of  deteriorating erythrocytes and recycling of their hemoglobin. Both contain  cells (see leukocyte) that remove foreign material and initiate an antibody-  producing process. The spleen becomes enlarged in some infections. Its  rupture in high-impact injuries may require surgical removal, which  leaves the patient more susceptible to overwhelming infection.</p><p>Split ancient Spalatum Seaport (pop., 2001: 188,694), Dalmatia,  Croatia. The Romans established the colony of Salonae nearby in 78 bc,  and the emperor Diocletian lived at Split until his death in ad 313. After  the Avars sacked the town in 615, the inhabitants built a new town within  Diocletian�s 7-acre (3-hectare) palace compound; this �old town� has  been continuously inhabited since that time. Split came under Byzantine  rule in the 9th century, shifted to Venetian control in 1420, and was held  by Austria in the 18th and 19th centuries. It came under Yugoslavian rule  in 1918, finally becoming part of independent Croatia in 1992. The port  facilities were destroyed in World War II, but the old city was little-  damaged, and repairs were subsequently made. Split is a commercial,  educational, and tourist centre. Collectively with the historic royal resi�  dences, fortifications, and churches in the city, the palace was designated  a UNESCO World Heritage site in 1979.</p><p>Spock, Benjamin (McLane) (b. May 2, 1903, New Haven, Conn.,  U.S.�d. March 15, 1998, La Jolla, Calif.) U.S. pediatrician. He received  his M.D. from Columbia University and later practiced pediatrics and  taught psychiatry and child development. His Common Sense Book of  Baby and Child Care (1946; 7th ed., 1998, Dr. Spock�s Baby and Child  Care), which urged parental flexibility and reliance on common sense and  discouraged corporal punishment, influenced generations of parents. Con�  tinually revised and updated to address new social and medical issues, it  has sold over 50 million copies in 39 languages. In 1967 he ceased his  medical practice to devote himself to the anti-Vietnam War movement.  His advocacy late in life of a vegan (see vegetarianism) diet for children  aroused great controversy.</p><p>spoils system or patronage system In U.S. politics, the practice  by political parties of rewarding partisans and workers after winning an  election. Proponents claim it helps maintain an active party organization  by offering supporters jobs and contracts. Critics charge that it awards  appointments to the unqualified and is inefficient because even jobs unre�  lated to public policy change hands after an election. In the U.S., the  Pendleton Civil Service Act (1883) was the first step in introducing the merit  system in the hiring of government workers. The merit system has almost  completely replaced the spoils system.

It was incorporated in 1881  after the arrival of the Northern Pacific Railway. A fire in 1889 destroyed  much of the city, but it soon was rebuilt and developed into a trade and  shipping hub for the surrounding region. Completion of the Grand Cou�  lee Dam Project (1941) assured industrial growth. Spokane is home to  Gonzaga University (1887) and is a gateway to the resorts of Mount Spo�  kane and several national forests.</p><p>sponge Any of some 5,000 species (phylum Porifera) of permanently  affixed (sessile), mostly marine, solitary or colonial invertebrates, found  from shallow to deep (more than 30,000 ft, or 9,000 m) waters. Simple  sponges are hollow cylinders with a large opening at the top through  which water and wastes are expelled. A thin, perforated outer epidermal  layer covers a porous skeleton, which is composed of interlocking spi�  cules of calcium carbonate, silica, or spongin (found in 80% of all  sponges), a proteinaceous material. The body, ranging in diameter or  length from 1 in. (2.5 cm) to several yards, may be fingerlike, treelike,  or a shapeless mass. Sponges lack organs and specialized tissue; flagel�  lated cells move water into the central cavity through the perforations,  and individual cells digest food (bacteria, other microorganisms, and  organic debris), excrete waste, and absorb oxygen. Sponges can repro�  duce asexually or sexually. Larval forms are free-swimming but all adults  are sessile. Since antiquity, sponges have been harvested for use in hold�  ing water, bathing, and scrubbing; because of overharvesting and newer  technologies, most sponges sold today are synthetic. See illustration oppo�  site.</p><p>spoonbill Any of six species (family Threskiornithidae) of long-necked,  long-legged wading birds, inhabitants of Old and New World estuaries,  saltwater bayous, and lakes. They are 24-32 in. (60-80 cm) long and have  a short tail and a long, straight bill that is spatulate at the tip. Most spe�  cies are white, sometimes rose-tinged; the roseate spoonbill (Ajaia ajaja )  of North and South America is deep pink and strikingly beautiful. With a  side-to-side motion of the bill, they sweep mud and shallow water for  fishes and crustaceans. They fly with neck and legs extended and wings  flapping steadily. Breeding colonies build stick nests in low bushes and  trees. Some species, including the black-billed spoonbill, are endangered.  See also ibis.</p><p>spoonerism Reversal of the initial letters or syllables of two or more  words, such as �I have a half-warmed fish in my mind� (for �half-formed  wish�) and �a blushing crow� (�a crushing blow�). The word is derived  from the name of William Archibald Spooner (1844-1930), a distin�  guished Anglican clergyman and warden of New College, Oxford, a ner�  vous man who committed many �spoonerisms.� Such transpositions are  often made intentionally for comic effect.</p><p>spore Reproductive cell capable of developing into a new individual  without fusing with another reproductive cell. Spores thus differ from  gametes, which must fuse in pairs in order to create a new individual.  Spores are agents of nonsexual reproduction; gametes are agents of sexual  reproduction. Spores are produced by bacteria, fungi (see fungus), and  green plants. Bacterial spores serve largely as a resting, or dormant, stage  in the life cycle, preserving the bacterium through periods of unfavorable  conditions. Many bacterial spores are highly durable and can germinate  even after years of dormancy. Fungal spores serve a function similar to  that of seeds in plants; they germinate and grow into new individuals under  suitable conditions of moisture, temperature, and food availability. Among  green plants (all of which have a life cycle characterized by alternation  of generations), spores are the reproductive agents of the nonsexual gen�  eration (sporophyte), giving rise to the sexual generation (gametophyte).</p><p>sporophyte \'spor-9- 1 fit\ In many plants and algae, the nonsexual phase  in the alternation of generations, or an individual representing the phase.  The alternate, sexual phase is the gametophyte. In the sporophyte phase, a  diploid (see ploidy) plant body grows and eventually produces spores  through meiosis. These spores divide by mitosis to produce haploid game-  tophytes, which then can carry out sexual reproduction.</p><p>sports and games Recreational or competitive activities that involve  physical skill, intellectual acumen, and often luck (especially in the case  of games of chance).

Its surface is perforated by small openings (incurrent  pores) formed by tubelike cells (porocytes), which open into the internal cavity. A  gelatinous middle layer contains the skeletal elements (spicules and spongin fibers)  as well as amebocytes active in digestion, waste removal, and spicule and spongin  formation. Flagellated collar cells (choanocytes) line the internal cavity, create cur�  rents to move water containing oxygen and food into the sponge, and engulf and  digest food particles. Water and wastes are expelled through the ostium opening,  whose size can be altered to regulate water flow through the sponge.</p><p>ENCYCLOPEDIA BRITANNICA, INC.</p><p>gathering activities.

The cars are designed for quick response, easy  maneuverability, and high-speed driving. Unlike the cars used in Grand  Prix racing, the sports car is usually series-produced, seldom handmade,  and the reputation of the car maker (Porsche, Jaguar, etc.) is thus put at  stake. The most famous international sports-car race is that at Le Mans,  France.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>sports medicine &#x25BA; Springfield rifle I 1805</p><p>sports medicine Medical and paramedical supervision and treatment  of athletes.

Pre�  vention identifies any predisposition to injury or illness and covers  warmup, stretching, and design and use of protective equipment. Many  surgical techniques developed in sports medicine, particularly for knee  injuries, are now used for the general population. Rehabilitation (see physi�  cal medicine AND rehabilitation) prepares an injured or ill athlete to return  to activity after initial treatment.</p><p>spotted fever See Rocky Mountain spotted fever</p><p>sprat or brisling Species (Sprattus sprattus ) of edible fish in the her�  ring family. Sprats are silver marine fishes that form enormous schools in  western European waters. Less than 6 in. (15 cm) long, they are espe�  cially valuable for canning as sardines. They are eaten fresh, tinned in oil,  pickled, or smoked.

Located about midway between Vietnam and the  Philippines, the group is claimed variously by Vietnam, China, Taiwan,  Malaysia, and the Philippines. Of the 12 main islets, the largest is the  90-acre (36-hectare) Itu Aba. Turtles and seabirds are the only permanent  inhabitants. After World War II, China established a garrison on Itu Aba,  which has been maintained by the Chinese government on Taiwan. All  other claimants also have small military forces on several of the islands.</p><p>spraying and dusting Standard methods of applying pest-control  chemicals and other compounds to plants, animals, soils, or agricultural  products. For spraying, chemicals are dissolved or suspended in water or,  less commonly, in an oil-based carrier. The mixture is then applied as a  fine mist. In dusting, dry, finely powdered chemicals may be mixed with  an inert carrier and applied with a blower. In fumigation, gases or the  vapours of volatile compounds are held in contact with the materials to  be treated. Sprays and dusts are used to control insects, mites, fungi, and  bacterial diseases of plants; disease-spreading insects, such as lice and  flies, on animals; and weeds. They are also used to apply mineral fertil�  izers, to increase or decrease fruit set, to delay the dropping of nearly  mature fruits, and to defoliate plants to facilitate harvesting (e.g., of cot�  ton; see defoliant). Sprays adhere to treated surfaces better than dusts do.  Fumigation may be used to control insects and some diseases in stored  products or to control insects and sometimes fungi and weeds in soil.  Increasing use of spraying and dusting has prompted concern over their  impact on the environment, the food chain, the water supply, and public  health. New chemicals and precautions have only partially allayed these  concerns.

It is characterized by the frequent juxtaposition of  single accented syllables and by the occurrence of feet with varying num�  bers of syllables whose sequence is interrupted by unstressed syllables  that are not counted in the scansion. Because stressed syllables often occur  sequentially, the rhythm is said to be �sprung.� This system of prosody  was developed by Gerard Manley Hopkins, who saw it as the basis of such  early English poems as William Langland�s Piers Plowman.</p><p>spurge One of the largest flowering-plant genera ( Euphorbia ), with more  than 1,600 species. It takes its com�  mon name from a group of annual  herbs used as purgatives, or spurges.</p><p>Many spurges are important as orna�  mentals or as sources of drugs; many  others are weeds. One of the best-  known is the poinsettia. Euphorbia is  part of the family Euphorbiaceae,  which contains about 7,500 species  of flowering annual and perennial  herbs and woody shrubs or trees in  275 genera; most are found in tem�  perate and tropical regions. Flowers  usually lack petals; those of Euphor�  bia are borne in cup-shaped clusters.</p><p>The fruit is a capsule. Leaves are usu�  ally simple. The stems of many spe�  cies contain a milky latex. In addition  to Euphorbia, economically impor�  tant family members include the  CASTOR-OIL PLANT, CROTON, CASSAVA, and RUBBER TREE.</p><p>Sputnik \'sput-nik\ Any of a series of Earth-orbiting spacecraft whose  launching by the Soviet Union inaugurated the space age. Sputnik 1, the  world�s first artificial satellite (October 1957), remained in orbit until early  1958, when it reentered Earth�s atmosphere and burned up. Sputnik 2 car�</p><p>ried a dog, Laika, the first living creature to orbit Earth; since Sputnik 2  was not designed to sustain life, Laika did not survive the flight. Eight  more missions with similar satellites carried out experiments on various  animals to test life-support systems and reentry procedures and to furnish  data on space temperatures, pressures, particles, radiation, and magnetic  fields.</p><p>Spyri Vshpe-re\, Johanna orig. Johanna Heusser (b. June 12,  1829, Hirzel, Switz.�d. July 7, 1901, Zurich) Swiss writer. Living in  Zurich with her lawyer husband, Spyri wrote books, many widely trans�  lated, that are imbued with her love of her homeland, feeling for nature,  unobtrusive piety, and cheerful wisdom. She is best remembered for her  popular novel Heidi (1880-81), a classic of children�s literature about an  orphan sent to live with her grandfather in the Swiss mountains.</p><p>SQL in full Structured Query Language. Computer programming  language used for retrieving records or parts of records in databases and  performing various calculations before displaying the results.

Squanto learned English after escap�  ing an attempt to sell him into slavery and joining the Newfoundland  Company. In Plymouth colony he was made Gov. William Bradford�s  Indian emissary. He also served as interpreter for Edward Winslow, the  Pilgrim representative, during his negotiations with Massasoit, chief of  the Wampanoag.</p><p>square In measurement, a device consisting of two straightedges set at  a right angle. It is used by carpenters and machinists to check the cor�  rectness of right angles, as a guide when drawing lines on materials before  cutting, or for locating holes. In mechanical drawing or drafting, a  T-shaped instrument known as a T square is used to establish a horizon�  tal reference on the drafting board.</p><p>square dance Dance for sets of four couples standing in square for�  mation. The most popular type of U.S. folk dance, it derived from the  quadrille and was originally called a square dance to distinguish it from  the contra, or longways, dance (for a double line of couples) and the round  dance (for a circle of couples). The U.S. square dance progresses through  specific patterns called or sung out to the dancers by a caller and accom�  panied by lively music played on instruments such as fiddle, banjo, accor�  dion, guitar, and piano.</p><p>Square Deal Term used by Pres. Theodore Roosevelt to describe his  approach to social problems. It embraced his idealistic view of labour,  citizenship, parenthood, and Christian ethics. He first used the term after  the settlement of a mining strike in 1902 to describe the ideal of peaceful  coexistence between big business and labour unions. The concept became  part of the Bull Moose Party platform when Roosevelt became its candi�  date in 1912.</p><p>square of opposition See square of opposition</p><p>squash Any of various fruits of the genus Cucurbita in the gourd fam�  ily, widely cultivated as vegetables and for livestock feed. The principal  species are C. maxima and certain varieties of C. pepo. Summer squash  is a quick-growing, small-fruited, nontrailing or bush type of C. pepo.  Diverse in form, colour, and surface texture, the fruits do not store well  and must be used soon after harvest (see zucchini). Winter varieties of  squash, C. maxima, are long-vining, generally large-fruited, long-season  types. Harvested fruits, in a wide range of sizes, shapes, and colours, can  be stored many months if kept dry and well above freezing. The rinds are  harder than those of summer squash and usually inedible. Examples  include acorn squash and pumpkin. Native to the Americas, squash was  widely cultivated by American Indians before Europeans arrived.</p><p>squash (rackets) Singles or doubles game played in a four-walled  court with a long-handled racket and a rubber ball. A descendant of rack�  ets, it probably originated in the mid-19th century at England�s Harrow  School. The standard international game uses a relatively soft, slow ball;  hardball squash, popular in the U.S., is played on a narrower court with  a harder, faster ball. The object of squash is to bounce, or rebound, the  ball off the front wall in such a way as to defeat an opponent�s attempt to  reach and return it.</p><p>Black spruce (Picea mariana)</p><p>GRANT HEILMAN-EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>squash bug &#x25BA; Sri Lanka I 1807</p><p>squash bug or leaf-footed bug Any of more than 2,000 widely  distributed insect species (family Coreidae), including many important  plant pests. Most species are dull-coloured and more than 0.4 in. (10 mm)  long. Many have enlarged, flattened extensions on the legs. The North  American squash bug (Anasa tristis ) is an important pest of squash,  melon, and pumpkin (plants in the gourd family). It is basically yellow  but is covered with black pits that make it look black. The larvae feed  underground, and the piercing and sucking mouthparts of the adults enable  them to attack the parts of plants that insecticides rarely penetrate.</p><p>squash tennis Singles racket game resembling squash rackets, played  with an inflated ball the size of a tennis ball. Played in virtually the same  court as squash rackets, squash tennis makes fewer demands on the legs  in pursuing the ball but puts a greater premium on agility and quickness  of foot and reflexes in turning and spinning.</p><p>squatter sovereignty See popular sovereignty</p><p>Squaw Valley Valley, eastern California, U.S. Squaw Valley is located  in the Sierra Nevada range on the eastern slope of Squaw Peak, northwest  of Lake Tahoe.

July 4, 1819, Wilmington, Del.,  U.S.�d. Oct. 25, 1900, Brooklyn, N.Y.) U.S. pharmaceutical manufac�  turer. He earned a medical degree and later worked on U.S. Navy ships;  his work alerted him to the poor quality of the medicines supplied to the  Navy, which he persuaded to manufacture its own drugs. At the Brook�  lyn Naval Hospital (from 1851) he devised a safe method for making  anesthetic ether and also discovered processes for making chloroform,  fluid extracts, and bismuth salts. In 1858 he set up his own Brooklyn  laboratory; the Union Army during the Civil War relied heavily on his  drugs, and by 1883 he was manufacturing 324 products and selling them  around the world. A Quaker idealist, he refused to patent his medicines,  and he crusaded for purity in drug manufacture. He did not live to see the  culmination of his work: the Pure Food and Drug Act of 1904.</p><p>squid Any of nearly 400 species of 10-armed cephalopods, found in both  coastal and oceanic waters, that prey on fishes and crustaceans. They  range from less than 0.75 in. (1.5 cm) to more than 65 ft (20 m) long (in  the case of the giant squid). Two of the 10 arms are long, slender ten�  tacles; each has an expanded end and four rows of suckers with toothed,  hard-edged rings. An internal shell supports the slender tubular body of  most species. Squid eyes, almost as complex as human eyes, are usually  set into the sides of the head. Squids may be swift swimmers (propelling  themselves by contracting and relaxing their mantle or by undulating their  two fins) or mere drifters; water expelled from a funnel below the head  can propel the squid backward. Like the octopus, the squid may emit an  inky cloud from its ink sac when in danger from sperm whales, fishes, or  humans, among other predators.</p><p>Squid (///ex coindeti) swimming forward</p><p>DOUGLAS P.

They eat fruit,  insects, and small animals. They are  10-16 in. (25�40 cm) long and have  a heavy, nonprehensile, black-tipped  tail, 15-19 in. (37-47 cm) long. They  have a small white face, large eyes,  and large, usually tufted, ears. The  short, soft coat is grayish to green�  ish, with yellow or orange arms,  hands, and feet. The crown of the  common squirrel monkey ( S. sci-  ureus) is olive or grayish; the red-  backed squirrel monkey (S.  oerstedii ) has a black crown and red�  dish back.</p><p>Sraosha \srau-'sha\ In Zoroastrianism and Parsiism, the divine being who  is the messenger of Ahura Mazda and the embodiment of the divine word.  He serves as the mediator between the human and the divine. Zoroastri-  ans believe that no ritual is valid without his presence. He is depicted as  a strong and holy youth who lives in a celestial thousand-pillared house.  He chastises the demons that harass people every night, and he leads the  righteous soul through the ordeal of judgment three days after death. At  the end of time, he will be the agent of the extermination of evil.</p><p>Sravasti \shra-'v3s-te\ Ancient city, northeastern Uttar Pradesh, north�  ern India. In Buddhist times (6th century BC-6th century ad), it was the  capital of Kosala and a prosperous trading centre.

Its ruins include those of a monastery.</p><p>Sri Lanka V.sre-'laq-koN officially Democratic Socialist Republic  of Sri Lanka formerly Ceylon Island country in the Indian Ocean, off  the southeastern coast of India. Area: 25,332 sq mi (65,610 sq km). Popu�  lation (2005 est.): 20,743,000. Capitals: Colombo (executive), Sri  Jayewardenepura Kotte (legislative and judicial). About three-fourths of  the population is Sinhalese; other ethnic groups include Tamils and Mus�  lims. Languages: Sinhala, Tamil (both official); also English. Religions:  Buddhism; also Hinduism, Islam, Christianity. Currency: Sri Lanka rupee.  Highlands make up Sri Lanka�s south-central region and core, with nar�  row gorges and deep river valleys. The surrounding lowlands include hills  and fertile plains. The developing mixed economy is largely based on  agriculture, services, and light industries. Clothing, tea, gemstones, and  rubber are exported. The island is world-famous for its gemstones, which  include sapphires, rubies, and topaz. It is also a major producer of high-  grade graphite. Sri Lanka is a republic with one legislative house; its head  of state and government is the president, assisted by the prime minister.  The Sinhalese people are probably the result of aboriginal inhabitants  mixing with Indo-Aryans who began migrating from India c. the 5th cen�  tury bc. The Tamils were later immigrants from Dravidian India, migrat�  ing over a period from the early centuries ad to c. 1200. Buddhism was  introduced during the 3rd century bc. As Buddhism spread, the Sinhalese  kingdom extended its political control over the island but lost it to invad�  ers from southern India in the 10th century. Between 1200 and 1505, Sin�  halese power gravitated to southwestern Sri Lanka, while a southern  Indian dynasty seized power in the north and established the Tamil king�  dom in the 14th century. Foreign invasions from India, China, and Malaya  occurred in the 13th�15th centuries. In 1505 the Portuguese arrived, and  by 1619 they controlled most of the island. The Sinhalese enlisted the  Dutch to help oust the Portuguese, and the island eventually came under  the control of the Dutch East India Company, which relinquished it in 1796  to the British. In 1802 it became the British crown colony of Ceylon,  which gained independence in 1948. It became the Republic of Sri Lanka  in 1972 and took its present name in 1978.

Founded in 1925 by Adolf Hitler as a  personal bodyguard, it was directed from 1929 by Heinrich Himmler, who  enlarged its membership from fewer than 300 to more than 250,000.  Wearing black uniforms and special insignia (lightning-like runic S�s,  death�s-head badges, and silver daggers), the SS considered itself supe�  rior to the SA, whom they purged on Hitler�s orders in 1934. The corps  was divided into the General SS (Allgemeine-SS), which dealt with police  matters and included the Gestapo, and the Armed SS (Waffen-SS), which  included the concentration-camp guards and the 39 regiments in World  War II that served as elite combat troops. SS men were schooled in racial  hatred and absolute obedience to Hitler. They carried out massive execu�  tions of political opponents, Roma (Gypsies), Jews, communists, parti�  sans, and Russian prisoners. In 1946 the SS was declared a criminal  organization at the NOrnberg trials.</p><p>St. Denis V.sant-'den-osN, Ruth orig. Ruth Dennis (b. Jan. 20, 1877,  Newark, N.J., U.S.�d.

From 1906 to  1909 she toured in Europe to wide acclaim. In 1915 she and her husband,  Ted Shawn, established the Denishawn dance company and school to  present a new choreographic style of abstract �music visualization.� The  company frequently toured until it disbanded in 1931 when St. Denis and</p><p>Shawn separated. Her interest in the use of dance in religion led her to  found the Society of Spiritual Arts. She continued to perform, teach, and  lecture into the 1960s.</p><p>stability In mathematics, a condition in which a slight disturbance in a  system does not produce a significant disrupting effect on that system. A  solution to a differential equation is said to be stable if a slightly different  solution that is close to it when x = 0 remains close for nearby values of  x. Stability of solutions is important in physical applications because  deviations in mathematical models inevitably result from errors in mea�  surement. A stable solution will be usable despite such deviations.</p><p>stabilizer, economic See economic stabilizer</p><p>stadium Enclosure that provides a broad space for sports events and  tiers of seats for a large number of spectators. The name derives from a  Greek unit of measurement, the stade (about 607 ft, or 185 m), the length  of the footrace in the ancient Olympics. Shapes of stadiums have varied  depending on use: Some are rectangular with curved corners; others are  elliptical or U-shaped. As a type of long-span structure, the stadium played  a significant role in 20th-century construction technology. The building  of large stadiums has been greatly facilitated by the use of reinforced  concrete, steel, and membrane structures, which have made possible daring  new designs. The Houston Astrodome was the first major fully roofed sta�  dium. Cables contributed significantly to speed of construction, lightness  of roof, and economy in covered stadiums. The enormous Hubert H.  Humphrey Metrodome in Minneapolis (opened 1982) was built using a  cable system.</p><p>Stael Vstal\, Germaine de orig.

She early  gained a reputation as a lively wit.</p><p>She first became known for Letters  on the Works and the Character of  J.-J. Rousseau (1788). The most bril�  liant period of her career began in  1794, when she returned to Paris  after the Reign of Terror; her salon,  known for its literary and intellectual  figures, flourished, and she published  political and literary essays, notably  A Treatise on the Influence of the  Passions upon the Happiness of  Individuals and of Nations (1796),  an important document of European  Romanticism. In 1803 Napoleon, who  resented her opposition, had her ban�  ished from Paris, and she made the  family residence in Coppet, Switz.,  her headquarters. Probably her most important work is Germany (1810),  a serious study of German manners, literature and art, philosophy and  morals, and religion.

Founded by the daughter of Alfred  the Great, the town had its own mint from the reign of Aethelstan to that  of Henry II. After being chartered in 1206, it grew as a market town. Par�  liamentarians demolished its 11th-century walls and castle in 1643 dur�  ing the English Civil Wars. It is situated on the London-Birmingham-  Manchester road and rail routes; its industries include electrical and  mechanical engineering.

While elements such as  painted screens and wheeled plat�  forms were used in the Greek theatre  of the 4th century bc, most innova�  tions in stage design were developed  in the Italian Renaissance theatre,  where painted backdrops, perspec�  tive architectural settings, and  numerous changes of scenery were  common. Italian staging was intro�  duced in England in 1605 by Inigo  Jones for court masques. In the late  19th century staging was influenced  by the new naturalism, which called  for historically accurate sets. In the</p><p>Staffordshire lead-glazed earthenware  figure, c. 1780; in the Victoria and  Albert Museum, London</p><p>20th century simplified stage design</p><p>focused attention on the actor. Stage design has been greatly affected by  advances in lighting, from the use of candles in the Renaissance to oil  lamps in the 18th century and gas and electric lights in the 19th century.  Modern stage lighting, which employs computerized control boards to  achieve complex effects, can unify all the visual elements of a stage pro�  duction. See also stage machinery.</p><p>stage machinery Devices designed for the production of theatrical  effects, including rapid scene changes, lighting, sound effects, and illu�  sions. Such devices have been in use since the 5th century bc, when the  Greeks developed a crane to lower to the stage an actor playing a god (see  deus ex machina), as well as movable scenery mounted on wheels. Medi�  eval mystery plays used trapdoors to allow the emergence of devils and  used flying machines for angels. In the Italian Renaissance, elaborate  machinery was used for spectacles produced in the churches on holy days.  In the 17th century the Italian Giacomo Torelli (1608-78) invented a sys�  tem for moving the stage wings that made it possible to change scenery  quickly. In the 19th century magical illusions were created with mirror  devices and refined trapdoors. By the late 20th century spectacle had  fallen out of fashion except in musical theatre, but hydraulic stage machin�  ery allowed for swift and soundless scene changes. See also stage design.</p><p>stagecoach Public coach pulled by horses regularly traveling a fixed  route between stations or stages. Stagecoaches appeared in London by  1640 and in Paris by 1660. In the 19th century they were most widely  used in the U.S. and in England, where in 1828 stagecoaches ran 12 times  a day from Leicester to London. In the U.S. they were the only means of  travel for long distances overland, carrying passengers and mail to loca�  tions especially in the West. As railroad travel became more common,  stagecoach travel diminished except to remote locations.</p><p>staged rocket Launch vehicle driven by several rocket systems mounted  in vertical sequence. The lowest, or first, stage ignites and lifts the vehicle  (sometimes assisted by attached booster rockets) at increasing speed until  its propellants have been used up. The first stage then drops off, which  makes the vehicle lighter, and the second stage ignites and accelerates the  vehicle further. The use of additional stages generally follows the same  pattern until the payload�the spacecraft �has reached the velocity  needed to achieve orbit or leave the vicinity of Earth. The number of  stages required depends on the details of the mission, the launch vehicle�s</p><p>characteristics, and other factors. Some early vehicles needed five stages  to reach orbit; most current launch vehicles need only two.</p><p>Stagg, Amos Alonzo (b. Aug. 16, 1862, West Orange, N.J., U.S.�d.

Stained glass is often made in  large, richly detailed panels that are set together in a framework of lead.  Like all coloured glass, it acquires its colour by the addition of metallic  oxides to molten glass. A purely Western phenomenon, stained glass origi�  nated as a fine art of the Christian church, beginning in the 12th�13th  century, when it was combined with Gothic architecture to create brilliant,  moving effects. A decline set in after the 13th century, when stained-glass  artists began to seek the realistic effects sought by Renaissance painters,  effects to which the technique was less suited and which diverted artists  from exploiting the all-important light-refracting quality of glass.

Other ele�  ments, such as nickel, molybdenum, titanium, aluminum, niobium, cop�  per, nitrogen, sulfur, phosphorus, and selenium, may be added to increase  corrosion resistance to specific environments, enhance resistance to oxi�  dation (see oxidation-reduction), and impart special characteristics.</p><p>stairway or staircase Series or flight of steps that provides a means  of moving from one level to another. The earliest stairways seem to have  been built with walls on both sides, as in Egyptian pylons dating from the  2nd millennium bc. The Romans were noted for their monumental stairs.  The modem use of steel and reinforced concrete has made possible the  curves and sweeps of contemporary design. Staircases have traditionally  been built of wood, marble or stone, and iron or steel. A step�s horizon�  tal surface is called its tread, the vertical front its riser. Traditional wooden  staircases are constructed with stringers, beams inclined to the angle of  the staircase. Stringers are supported by newel posts, which also support  the handrail, forming a balustrade.</p><p>Staked Plain See Liano Estacado</p><p>stalactite and stalagmite \st3-Tak- 1 tIt...st3-Tag- 1 m!t\ Elongated  forms of various minerals deposited from solution by slowly dripping  water.

Iosif Vissarionovich Dzhugashvili (b.</p><p>Dec. 21, 1879, Gori, Georgia, Russian Empire�d. March 5, 1953, Mos�  cow, Russia, U.S.S.R.) Soviet politician and dictator. The son of a cob�  bler, he studied at a seminary but was expelled for revolutionary activity  in 1899. He joined an underground revolutionary group and sided with  the Bolshevik faction of the Russian Social-Democratic Workers' Party in  1903. A disciple of Vladimir Lenin, he served in minor party posts and was  appointed to the first Bolshevik Central Committee (1912). He remained  active behind the scenes and in exile (1913-17) until the Russian Revolu�  tion of 1917 brought the Bolsheviks to power. Having adopted the name  Stalin (from Russian stal, �steel�), he served as commissar for nationali�  ties and for state control in the Bolshevik government (1917-23). From  1922 he became secretary-general of the party�s Central Committee, a  post that later provided the power base for his dictatorship, and was also  a member of the Politburo. After Lenin�s death (1924), Stalin overcame  his rivals, including Leon Trotsky, Grigory Zinovyev, Lev Kamenev, Nikolay  Bukharin, and Aleksey Rykov, and took control of Soviet politics. In 1928  he inaugurated the Five-Year Plans that radically altered Soviet economic  and social structures and resulted in the deaths of many millions. In the  1930s he contrived to eliminate threats to his power through the purge tri�  als and through widespread secret executions and persecution. In World  War II he signed the German-Soviet Nonaggression Pact (1939), attacked  Finland (see Russo- Finnish War), and annexed parts of eastern Europe to  strengthen his western frontiers. When Germany invaded Russia (1941),  Stalin took control of military operations. He allied Russia with Britain  and the U.S.; at the Tehran, Yalta, and Potsdam conferences, he demon�  strated his negotiating skill. After the war he consolidated Soviet power  in eastern Europe and built up the Soviet Union as a world military power.  He continued his repressive political measures to control internal dissent;  increasingly paranoid, he was preparing to mount another purge after the  so-called Doctors' Plot when he died. Noted for bringing the Soviet Union  into world prominence, at terrible cost to his own people, he left a legacy  of repression and fear as well as industrial and military power. In 1956  Stalin and his personality cult were denounced by Nikita Khrushchev.</p><p>Stalin Peak See Imeni Ismail Samani Peak  Stalina bad See Dushanbe  Stalingrad See Volgograd</p><p>Stalingrad, Battle of (1942-43) Unsuccessful German assault on the  Soviet city in World War II. German forces invaded the Soviet Union in  1941 and had advanced to the suburbs of Stalingrad (now Volgograd) by  the summer of 1942. Met by a determined Red Army defense commanded  by Vasily Chuikov, they reached the city�s centre after fierce street fight�  ing. In November the Soviets counterattacked and encircled the German  army led by Friedrich Paulus, who surrendered in February 1943 with  91,000 troops. The Axis forces (Germans, Romanians, Italians, and Hun�  garians) suffered 800,000 deaths; in excess of 1,000,000 Soviet soldiers  died. The battle marked the farthest extent of the German advance into  the Soviet Union.</p><p>Stalinism Method of rule, or policies, of Joseph Stalin in the Soviet  Union and his imitators elsewhere in the Soviet bloc. On taking power,  Stalin brooked no dissent from party policies, of which he assumed the  role of sole infallible interpreter. He postponed the struggle for world pro�  letarian revolution, focusing instead on �socialism in one country.� He  decreed the wholesale collectivization of Russian agriculture and a pro�  gram of rapid industrialization, which, though broadly effective, resulted  in the deaths of many millions. Purges in the 1930s (see Purge Trials)  resulted in the deaths of millions more, as opponents were branded trai�  tors and executed or sent to the Gulag. After Stalin�s death Nikita Khrush�  chev repudiated Stalinism (1956) as an aberration. See also Leninism,  Trotskyism.</p><p>Stalino See Donetsk</p><p>Stamboliyski \,stam-bo-Te-ske\, Aleksandur (b.

He opposed the pro-German king Ferdinand and supported  the Allies in World War I, for which he was imprisoned (1915-18). He led  the 1918 insurrection that forced Ferdinand�s abdication, and he was cho�  sen premier of the new Bulgarian republic in 1919.

Stamens produce pollen in  terminal saclike structures called anthers. The number of stamens is usu�  ally the same as the number of petals. Stamens usually consist of a long  slender stalk, the filament, with the anthers at the tip. Some stamens are  similar to leaves, with the anthers at or near the margins. Small secretory  structures called nectaries are often found at the base of the stamens and  provide food rewards for insect and bird pollinators (see pollination).

The company originated in 1863, when John D. Rockefeller started  a Cleveland, Ohio, refining firm, which, with other facilities, was incor�  porated as the Standard Oil Company in 1870. By 1880, through elimi�  nation of competitors, mergers, and use of favourable railroad rebates, it  controlled the refining of 90-95% of all oil produced in the U.S. In 1882  Standard Oil and affiliated oil companies were combined in the Standard  Oil Trust, which eventually included some 40 corporations. In 1892 the  Ohio Supreme Court ordered the trust dissolved, but it continued to oper�  ate from headquarters in New York and later New Jersey. Its monopolis�  tic practices were exposed in Ida Tarbell�s History of the Standard Oil  Company (1904), and after a lengthy antitrust suit by the U.S. govern�  ment (see antitrust law), the Standard Oil empire was broken up in 1911.  Although eight companies retained �Standard Oil� in their names after  1911, by the late 20th century the name had all but disappeared, even  though former Standard Oil divisions continued to dominate the U.S.  petroleum business. In 1931 Standard Oil Company of New York merged  with Vacuum Oil Company (another trust company) to form Socony-  Vacuum, which in 1966 became Mobil Oil Corp. Standard Oil (Indiana)  absorbed Standard Oil of Nebraska in 1939 and Standard Oil of Kansas  in 1948 and was renamed Amoco Corp. in 1985. Standard Oil of Cali�  fornia acquired Standard Oil of Kentucky in 1961 and was renamed Chev�  ron Corp. in 1984. Standard Oil Company (New Jersey) changed its name  to Exxon Corp. in 1972. In 1987 British Petroleum Company PLC (BP)  completed the purchase of Standard Oil Company (Ohio). Further con�  solidation occurred in 1998, when BP merged with Amoco, and in 2002,  when Exxon merged with Mobil.</p><p>standard time Official local time of a region or country. Local mean  solar time depends on longitude; it advances by four minutes per degree  eastward. The Earth can thus be divided into 24 standard time zones, each  approximately 15� in longitude.

The times in different zones usually differ by an integral  number of hours; minutes and seconds are the same.

The foundation sire was an English Thoroughbred  imported in 1788; his progeny were bred with other breeds, especially the  Morgan, to produce speedy trotters and pacers. The Standardbred�s height  is 15-16 hands (60-64 in. [152-163 cm]); its weight is 900-1,000 lb  (410-450 kg). Colour varies, but the most common is bay. �Standard�  refers to a requirement imposed in 1871 that, to be registered, a horse  must meet certain standards of speed (e.g., trotting a mile in 2.5 minutes).</p><p>standardization In industry, the development and application of stan�  dards that make it possible to manufacture a large volume of interchange�  able parts. Standardization may focus on engineering standards, such as  properties of materials, fits and tolerances, and drafting practices; or on  product standards, which detail the attributes of manufactured items and  are embodied in formulas, descriptions, drawings, or models. Adoption of  standards makes it easier for firms to communicate with their suppliers.  Standards are also used within industries to prevent conflict and duplica�  tion of effort. Governmental departments, trade associations, and techni�  cal associations help to set standards within industries; these are  coordinated and promoted by organizations such as the American National  Standards Institute (ANSI) and the International Organization for Stan�  dardization (ISO).</p><p>Standards and Technology, National Institute of See Bureau  of Standards</p><p>standing In law, the status of being qualified to bring a legal matter  before a court because one has a sufficient and protectable interest in its  outcome.

From age  14 he acted with his family�s amateur dramatic group, and in 1888 he  cofounded a permanent dramatic company. He won praise in 1891 for his  first independent production, The Fruits of Enlightenment. In 1898 he and  Vladimir Nemirovich-Danchenko (1858-1943) founded the Moscow Art  Theatre; that year it restaged Anton Chekhov�s The Seagull to great  acclaim. Stanislavsky continued to direct and act in many Russian plays,  including Chekhov�s Uncle Vanya (1899) and The Cherry Orchard  (1904). He trained his actors to achieve greater realism by identifying  deeply with their characters, a technique that became known as the  Stanislavsky method. His company toured Europe and the U.S. (1922-24),  where his method influenced the later development of the Group Theatre  and the Actors Studio.</p><p>Stanislavsky method or method acting Influential system of  dramatic training developed by the Russian actor, producer, and theore�  tician Konstantin Stanislavsky.

The Milky Way Galaxy contains hundreds of billions  of stars; only a very small fraction are visible to the unaided eye. The  closest star is about 4.2 light-years from the Sun; the most distant are in  galaxies billions of light-years away. Single stars such as the Sun are the  minority; most stars occur in pairs, multiple systems, or clusters (see  BINARY STAR; GLOBULAR CLUSTER; OPEN CLUSTER). CONSTELLATIONS Consist not of  such groupings but of stars in the same direction as seen from Earth. Stars  vary greatly in brightness (magnitude), colour, temperature, mass, size,  chemical composition, and age. In nearly all, hydrogen is the most abun�  dant element. Stars are classified by their spectra (see spectrum), from  blue-white to red, as O, B, A, F, G, K, or M; the Sun is a spectral type G  star. Generalizations on the nature and evolution of stars can be made from  correlations between certain properties and from statistical results (see  Hertzsprung-Russell diagram). A star forms when a portion of a dense inter�  stellar cloud of hydrogen and dust grains collapses from its own gravity.  As the cloud condenses, its density and internal temperature increase until</p><p>Sir Henry Morton Stanley, detail of a  portrait by Sir Hubert von Herkomer; in  the City Museum &amp; Art Gallery, Bristol,  Gloucestershire, England.</p><p>COURTESY OF THE CITY MUSEUM &amp; ART GALLERY, BRISTOL,  ENGLAND</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Star Chamber &#x25BA; Starr I 1813</p><p>it is hot enough to trigger nuclear fusion in its core (if not, it becomes a  brown dwarf).

The final stages  of a star�s evolution, when it no longer produces enough energy to coun�  teract its own gravity, depend largely on its mass and whether it is a com�  ponent of a close binary system (see black hole; neutron star; nova; pulsar;  supernova; white dwarf star).

It was employed extensively under Henry VIII because of its ability to  enforce the law when other courts were unable to do so because of cor�  ruption and influence. When Charles I used it to enforce unpopular politi�  cal and ecclesiastical policies, it became a symbol of oppression to his  and Archbishop William Laud�s parliamentary and Puritan opponents  (though it never imposed the death penalty), and it was abolished by the  Long Parliament in 1641.</p><p>Star of David See Star of David  Star Wars See Strategic Defense Initiative</p><p>starch Any of several white, granular organic compounds produced by  all green plants. They are polysaccharides with the general chemical for�  mula (C 6 H 10 O 5 ) n , where n may range from 100 to several thousand; the  constituent monosaccharides are glucose units made in photosynthesis. The  glucose chains are unbranched in amylose and branched in amylopectin,  which occur mixed in starches. Starch consumed by animals is broken  down into glucose by enzymes during digestion. Commercial starch is made  mainly from corn, though wheat, tapioca, rice, and potato starch are also  used. Starch has many uses in foods and the food industry, as well as in  the paper, textile, and personal-care products industries and in adhesives,  explosives, and oil-well drilling fluids and as a mold-release agent.

Since no court decision can have universal  application, the courts, in practice, must often decide that a previous deci�  sion does not apply to a particular case even though the facts and issues  appear to be closely similar. A strict application of stare decisis may lead  to rigidity and to legal hairsplitting, whereas too much flexibility may  result in uncertainty.</p><p>starfish or sea star Any of 1,800 echinoderm species (class Asteroi-  dea) that have regenerable arms surrounding an indistinct disk and that  inhabit all oceans.

Using hundreds of  thousands of informers, it monitored one-third of the population. Most of  its foreign operations were focused on West Germany�whose governing  circles and military and intelligence services it successfully penetrated�  and West Germany�s NATO allies. The Stasi was disbanded after German  reunification. In 1991 the newly reunified German government passed the  Stasi Records Law, under which East German citizens and foreigners were  granted the right to view their Stasi files.

The Dutch attempted to colonize the island  in 1630 but were thwarted by the Delaware Indian inhabitants until 1661,  when the Dutch West India Co. granted the island to the French and  settlements were established. Following the acquisition of New Nether-  land in 1664 by Great Britain, English and Welsh farmers established  homes and farms on the island. As Richmond, it became a borough of  New York City in 1898; Staten Island was made the official name in 1975.  Mostly residential, the island has some industry, including shipbuilding  yards, printing plants, and oil-storage tanks and refineries. It is the seat  of Wagner College (1883, moved from Rochester in 1918).</p><p>States General See Estates General</p><p>states' rights Rights or powers retained by the regional governments  of a federal union under the provisions of a federal constitution. In the  U.S., Switzerland, and Australia, the powers of the regional governments  are those that remain after the powers of the central government have been  enumerated in the constitution. The powers of both the state or regional  and national levels of government are defined clearly by specific provi�  sions of the constitutions of Canada and Germany. The concept of states�  rights is closely related to that of the 18th-century European concept of  state rights, which was invoked to legitimate the powers vested in sov�  ereign national governments. In the U.S. before the mid-19th century,  some Southern states claimed the right to annul an act of the federal gov�  ernment within their boundaries (see nullification), as well as the right to  secede from the Union. The constitutional question was resolved against  the South by the North�s victory in the American Civil War. In the civil  rights era, states� rights were invoked by opponents of federal efforts to  enforce racial integration in public schools. The federal government can  influence state policy even in areas that are constitutionally the purview</p><p>of the states (e.g., education, local road construction) through withhold�  ing funds from states that fail to comply with its wishes. In the late 20th  century the term came to be applied more broadly to a variety of efforts  aimed at reducing the powers of national governments.</p><p>statistical mechanics Branch of physics that combines the principles  and procedures of statistics with the laws of both classical mechanics and  quantum mechanics.

Statistics pro�  vides ways to design efficient experiments that eliminate time-consuming  trial and error. Double-blind tests for polls, intelligence and aptitude tests,  and medical, biological, and industrial experiments all benefit from sta�  tistical methods and theories. The results of all of them serve as predic�  tors of future performance, though reliability varies.

A steady-state universe has no beginning or end, and its average  density and arrangement of galaxies are the same as seen from every point.  Galaxies of all ages are intermingled. The theory was first put forward by  William Macmillan (1861-1948) in the 1920s and modified by Fred Hoyle  to deal with problems that had arisen in connection with the big-bang  model. Much evidence obtained since the 1950s contradicts the steady-  state theory and supports the big-bang model.</p><p>stealth Any military technology intended to make vehicles or missiles  nearly invisible to enemy radar or other electronic detection. Research in  antidetection technology began soon after radar was invented. In World  War II the Germans coated their U-boat snorkels with radar-absorbent  material. By the end of the 20th century the U.S. had developed models  of stealth technology, including the F-117 Nighthawk fighter-bomber and  the B-2 Spirit strategic bomber. The aircraft featured surface materials  and coatings that absorbed radar transmissions, faceted or rounded sur�  faces that reduced radar reflections, and shielded engine exhausts that  reduced infrared radiation. Stealth technology has also been incorporated  into the design of naval submarines and surface vessels.</p><p>steam Invisible gas consisting of vaporized water. When mixed with  minute droplets of water, it has a white, cloudy appearance. In nature,  steam is produced by the heating of underground water by volcanic pro�  cesses and is emitted from hot springs, geysers, fumaroles, and some vol�  canoes. Steam also can be generated on a large scale by technological  systems, such as those using fossil-fuel-burning boilers and nuclear reac�  tors. Modern industrial society relies on steam power; water is heated to  steam in power plants, and the pressurized steam drives turbines that pro�  duce electric current: thermal energy is converted to mechanical energy,  which is converted into electricity.</p><p>steam engine Machine that uses steam power to perform mechanical  work through the agency of heat (hence a prime mover). In a steam engine,  hot steam, usually supplied by a boiler, expands under pressure, and part  of the heat energy is converted into work. The rest of the heat may be  allowed to escape, or, for maximum engine efficiency, the steam may be  condensed in a separate apparatus, a condenser, at comparatively low  temperature and pressure. For high efficiency, the steam must decrease  substantially in temperature as it expands within the engine. The most  efficient performance (i.e., the greatest output of work in relation to the  heat supplied) is obtained by using a low condenser temperature and a  high boiler pressure. See also Thomas Newcomen, James Watt.</p><p>steamboat or steamship Watercraft propelled by steam; more nar�  rowly, a shallow-draft paddle-wheel steamboat widely used on rivers in  the 19th century, particularly the Mississippi River and its tributaries.  Though U.S. experiments with steam-powered boats began in 1787, the  first regular steamboat service, operating on the Mississippi, was not  established until 1812. Until c. 1870 the steamboat dominated the  economy, agriculture, and commerce of the middle of the U.S. Because  the paddle wheel created turbulence that eroded the banks of narrow  channels, river steamboats worked best on broad rivers. The first ocean  voyage of a steamboat occurred along the eastern coast of the U.S. in</p><p>1809, and Europeans soon developed steamboats capable of crossing  Europe�s stormy, narrow seas. The first transatlantic steamboat journey  was made by the Savannah in 1819, and the first commercial shipping  line, the Cunard Line (see Samuel Cunard), was established in 1840. The  screw propeller replaced the paddle wheel in oceanic steamers in the later  19th century. See also ocean liner.</p><p>Steamers Robert E.

Several iron-carbon constituents with different  compositions and/or crystal structures exist: austenite, ferrite, pearlite,  cementite, and martensite can coexist in complex mixtures and combina�  tions, depending on temperature and carbon content. Each microstructure  differs in hardness, strength, toughness, corrosion resistance, and electri�  cal resistivity, so adjusting the carbon content changes the properties. Heat  treating, mechanical working at cold or hot temperatures, or addition of  alloying elements may also give superior properties. The three major  classes are carbon steels, low-alloy steels, and high-alloy steels. Low-alloy  steels (with up to 8% alloying elements) are exceptionally strong and are  used for machine parts, aircraft landing gear, shafts, hand tools, and gears,  and in buildings and bridges. High-alloy steels, with more than 8% alloy�  ing elements (e.g., stainless steels) offer unusual properties. Making steel  involves melting, purifying (refining), and alloying, carried out at about  2,900�F (1,600�C). Steel is obtained by refining iron (from a blast fur�  nace) or scrap steel by the basic oxygen process, the open-hearth process,  or in an electric furnace, then by removing excess carbon and impurities  and adding alloying elements. Molten steel can be poured into molds and  solidified into ingots; these are reheated and rolled into semifinished  shapes which are worked into finished products. Some steps in ingot  pouring can be saved by continuous casting. Forming semifinished steel  into finished shapes may be done by two major methods: hot-working  consists primarily of hammering and pressing (together called forging),  extrusion, and rolling the steel under high heat; cold-working, which  includes rolling, extrusion, and drawing (see wire drawing), is generally</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1816 I steel drum &#x25BA; Stein</p><p>used to make bars, wire, tubes, sheets, and strips.

Sept. 1, 1729, Car�  marthen, Carmarthenshire, Wales) English journalist, dramatist, essayist,  and politician. He began his long friendship with Joseph Addison at school  and attempted an army career before turning to writing. He launched and  was the principal author (under the name Isaac Bicker staff) of the essay  periodical The Tatler (April 1709-January 1711), in which he created the  mixture of entertainment and instruction in manners and morals that he  and Addison would perfect in The Spectator. His attractive, often casual  writing style was a perfect foil for Addison�s more measured, erudite  prose. He made many later ventures into journalism, some politically par�  tisan, and held several government posts.

One of the greatest Dutch genre painters, he  is known for his humour and ability to capture subtle facial expressions,  especially of children. His figures, which became larger and more indi�  vidually characterized in his later works, were often shown playing cards  or skittles, or carousing in inns and taverns.

Eques�  trian steeplechase is popular in England, France, and Ireland, and to a  lesser extent in the U.S. The most famous equestrian steeplechase is the  Grand National. Track-and-field steeplechase dates back to a cross�  country race at the University of Oxford in 1850. The course and distance  were standardized at the 1920 Olympic Games.</p><p>Stefan Decansky \'ste-van-de-'kan-ske\ or Stefan Uros III (b.</p><p>1280�d. 1331) King of Serbia (1322-31). After rebelling against his  father, Stefan Uros II (r. 1282-1321), he was blinded, so that he would  be unfit to rule, and exiled (1314-20). He then showed he was not blind,  claiming a miraculous cure, and was made king. He allied with the los�  ing Andronicus II Palaeologus in the civil war with Andronicus III Palae-  ologus (1327-28) and was deposed by his son, Stefan Dusan.</p><p>Stefan Dusan \'dii-shan\ or Stefan Uros IV (b. 1308�d. Dec. 20,  1355) King of Serbia (1331-46) and emperor of the Serbs and Greeks  (1346-55). He deposed his father, Stefan Decansky, in 1331. The greatest  ruler of medieval Serbia, he began a war of conquest against Byzantium  in 1334, gaining control of Albania and Macedonia by 1346 and Epirus  and Thessaly by 1348. Dusan reformed the Serbian administration on the  Byzantine model and introduced a law code. His rule over former Byz�  antine lands was threatened by John VI Cantacuzenus, and his empire  broke apart soon after his death.</p><p>Stefan Nemanja or Stephen Nemanja \'ne-man-ya\ (d. 1200)  Founder of the Serbian state. He was grand zupan (clan leader) under  Byzantine rule in 1169. He allied himself with Venice and was defeated  by the avenging Byzantines, though he was later pardoned.

Stegner studied at  the University of Iowa and later taught at several universities, notably  Stanford. The Big Rock Candy Mountain (1943), a novel about a family  traveling around the West seeking their fortune, was his first critical and  popular success. His later novels include A Shooting Star (1961), Angle  of Repose (1971, Pulitzer Prize), and The Spectator Bird (1976, National  Book Award). His nonfiction includes two histories of the settlement of  Utah, Mormon Country (1942) and The Gathering of Zion (1964), and  Beyond the Hundredth Meridian (1954), a biography of John Wesley Pow�  ell.</p><p>stegosaur Any of the plated dinosaur species, including Stegosaurus,  of the Late Jurassic Epoch (159-144 million years ago). Stegosaurs were  four-legged herbivores that reached a maximum length of about 30 ft (9  m). The skull and brain were very small. The forelimbs were much shorter  than the hind limbs, the back was arched, and the feet were short and  broad. Stegosaurs had double rows of large, triangular, bony plates along  their backs and tail that may have been a temperature-regulating system.  Pairs of long, pointed, bony spikes on the end of the tail were probably  defensive weapons.</p><p>Steichen VstI-kon\, Edward (Jean) orig. Edouard Jean Stei-  chen (b.

He moved to New York City after studying history at Princeton  University and there began his innovative �black paintings� (1958-60),  incorporating symmetrical series of thin white stripes that replicated the  canvas shape when seen against their black backgrounds. As a leading  figure of Minimalism, in the mid 1960s he began using polychromy in an  influential series marked by intersecting geometric curvilinear shapes and  plays of vivid and harmonious colours. In the 1970s he began producing  sensuously coloured, mixed-media reliefs featuring more organic shapes.  He was given retrospective exhibitions at the Museum of Modern Art in  1970 and 1987.</p><p>Steller's sea cow See sea cow</p><p>stem Plant axis that emerges from the roots, supports the branches, bears  buds and shoots with leaves, and contains the vascular (conducting) tis�  sues (xylem and phloem) that transport water, minerals, and food to other  parts of the plant. The pith (a central core of spongy tissue) is surrounded  by strands (in dicots; see cotyledon) or bundles (in monocots) of conduct�  ing xylem and phloem, then by the cortex and outermost epidermis, or  bark. The cambium (an area of actively dividing cells) lies just below the  bark. Lateral buds and leaves grow out of the stem at intervals called  nodes; the intervals on the stem between the nodes are called intemodes.  In flowering plants, various stem modifications (rhizome, corm, tuber, bulb,  stolon) let the plant survive dormantly for years, store food, or sprout  asexually. All green stems perform photosynthesis, as do leaves; in plants  such as the cacti (see cactus) and asparagus, the stem is the chief site of  photosynthesis.</p><p>stem cell In living organisms, an undifferentiated cell that can produce  other cells that eventually make up specialized tissues and organs. There  are two major types of stem cells, embryonic and adult. Embryonic stem  cells are located in the inner mass of a blastocyst (an embryo at a very early  stage of development), and they eventually give rise to every cell type of  the adult organism. Adult stem cells are found in some tissues in the adult  body, such as the epidermis of the skin, the lining of the small intestine, and  the bone marrow, where they serve in the regeneration of old or worn tissue.  In cancer treatment, blood-forming adult stem cells are routinely harvested  from bone marrow, stored, and then reinfused into patients to replace blood  cells destroyed by chemotherapy or radiation therapy. This potential for</p><p>replacing damaged tissues has aroused great interest in using embryonic  stem cells to treat a number of other conditions, such as Parkinson disease,  severe burns, and damage to the spinal cord. Mouse embryonic stem cells  are widely used to create genetically modified mice that serve as models for  investigating human disease. However, the use of human embryonic stem  cells, which requires destroying the blastocysts from which they are  obtained, has raised objections by those who feel blastocyst-stage embryos  are human beings. The first human stem cell line was created in 1998, using  cells harvested from embryos produced through in vitro fertilization. The  use of human embryonic stem cells is allowed in some countries and pro�  hibited or restricted in others.</p><p>Stendhal \sta n -�dal,\�&gt;ig/w/i \sten-'dal\ orig. Marie-Henri Beyle (b.

By 1802  he was keeping a diary (posthu�  mously published as his Journal)  and writing other texts dealing with  his intimate thoughts. From 1806 he  served in Napoleon�s army; after the  French empire fell in 1814, he settled  in Italy. As a result of political and  romantic disappointments, he  returned to Paris. During 1821-30,  while leading an active social and  intellectual life, he wrote works  including the masterpiece The Red  and the Black (1830), a powerful  character study of an ambitious  young man that is also an acute pic�  ture of Restoration France. His other  major work, The Charterhouse of  Parma (1839), is remarkable for its  sophisticated rendering of human  psychology and its subtly drawn portraits. His unfinished autobiographi�  cal works.

He became a  coach and manager of the Dodgers and Braves but achieved his greatest  success with the New York Yankees (1949-61), leading the team to 10 pen�  nants (5 in consecutive years) and 7 World Series championships (5 in con�  secutive years) in 12 years. He later served as vice president and manager  of the newly formed New York Mets (1962-65), a team that became noted  for its dismal performance during these early years.

Matilda invaded  (1139), and, in a display of chivalry, Stephen had her escorted to Bristol.  She gained control of most of western England and captured Stephen in  battle (1141), but her arrogance provoked a rebellion, and she was forced  to leave England (1148). An agreement was reached whereby Matilda�s  son Henry of Anjou (later Henry II), who invaded England in 1153, was  named as Stephen�s successor.</p><p>Stephen known as Stephen the Great (b. 1435�d.

He repelled a  Hungarian invasion (1467) and later attacked Walachia (1471), by then  under Turkish vassalage. He defeated invading Turks (1475, 1476) and  contended with Polish and Hungarian designs on Moldavia. In 1503  Stephen signed a treaty preserving Moldavian independence at the cost  of an annual tribute to the Turks.</p><p>Stephen, Sir James Fitzjames, 1st Baronet (b. March 3, 1829,  London, Eng.�d.

As a member of the British viceroy�s council  in India (1869-72), he helped codify and reform Indian law. He later  taught at the Inns of Court (1875-79) and served as a judge of the High  Court of Justice (1879-91).

A forceful and ambitious monarch, he successfully defended Poland�s  eastern Baltic provinces against Russian incursion and forced the cession  of Livonia to Poland in 1582. He planned to unite Poland, Muscovy, and  Transylvania and was preparing to renew the war against Russia when he  died.</p><p>Stephen Decansky See Stefan Decansky  Stephen Dusan See Stefan Dusan  Stephen Nemanja See Stefan Nemanja</p><p>Stephens, Alexander H(amilton) (b.

He  served in the U.S. House of Representatives (1843-59), where he  defended slavery but opposed dissolution of the Union. When Georgia  seceded, he was elected vice president of the Confederacy. He supported  constitutional government, opposed attempts by Jefferson Davis to infringe  on individuals� rights, and advocated a program of prisoner exchanges.  He led the delegation to the Hampton Roads Conference (1865). After the  war he was held in Boston for five months. He served again in the House  (1873-82) and as governor of Georgia (1882-83).</p><p>Stephens, John Lloyd (b. Nov. 28, 1805, Shrewsbury, N.J., U.S.�d.  Oct. 12, 1852, New York, N.Y.) U.S. traveler and archaeologist.  Stephens�s travels in the Middle East resulted in two books. With his  illustrator friend Frederick Catherwood he embarked for Honduras in  1839 to explore ancient Maya ruins rumoured to exist. At Copan, Uxmal,  Palenque, and elsewhere, they identified major new sites. They described  their findings in Incidents of Travel in Central America, Chiapas, and  Yucatan (1841) and recounted a second trip in Incidents of Travel in  Yucatan (1843). Their books created a storm of popular and scholarly  interest in the region.</p><p>Stephens, Uriah Smith (b. Aug. 3, 1821, Cape May, N.J., U.S.�d.  Feb. 13, 1882, Philadelphia, Pa.) U.S. labour leader. Apprenticed as a tai�  lor, he became involved in reform movements such as abolitionism and  utopian socialism, and in 1862 he helped organize the Garment Cutters�  Association of Philadelphia. In 1869 he cofounded the Noble Order of the  Knights of Labor, the first national labour union in the U.S., and became  its first leader (or grand master workman). The high calling of the union  and the hostility of union-busters led Stephens to favour secrecy and ritual  in its meetings, which became increasingly controversial, as did  Stephens�s opposition to strikes. In 1878 he resigned his post.</p><p>Stephenson, George (b. June 9, 1781, Wylam, Northumberland,  Eng.�d. Aug. 12, 1848, Chester�  field, Derbyshire) English engineer,  principal inventor of the locomotive.</p><p>Son of a coal-mine mechanic, he  himself became chief mechanic at a  coal mine, where his interest in  steam engines led to experiments on  a machine to pull coal-filled cars out  of the mines. In 1815 he devised a  powerful �steam blast� system that  made the locomotive practical. In  1825 he built a steam locomotive for  the first passenger railway, from  Stockton to Darlington, which could  carry 450 people at 15 mph (24  km/hr). In 1829, assisted by his son  Robert Stephenson, he built his  improved locomotive, the Rocket,  which won a speed competition at 36  mph (58 km/hr) and became the  model for later locomotives. His  company built all eight locomotives  for the new Liverpool-Manchester railway (1830).</p><p>Stephenson, Robert (b. Oct. 16, 1803, Willington Quay, Northum�  berland, Eng.�d.

Build�  ing a railway from Newcastle to Berwick, he spanned the River Tyne with  a six-arch iron bridge. Called on to build a secure railroad bridge over the  Menai Strait to the Welsh mainland, Stephenson conceived a unique tubu�  lar design, the success of which led to his building other tubular bridges  in England and elsewhere.</p><p>Steptoe, Patrick (Christopher); and Edwards, Robert  (Geoffrey) (respectively b.

They perfected human in vitro fertilization, leading  to the birth of the first �test-tube baby� in 1978. Steptoe had conducted  research on sterilization and infertility and published Laparoscopy in  Gynaecology (1967). Edwards succeeded in 1968 in fertilizing human ova  outside the uterus. Their partnership, begun in 1968, resulted in the birth  of more than 1,000 babies.</p><p>stereochemistry Term originated c. 1878 by Viktor Meyer (1848-97)  for the study of stereoisomers (see isomer). Louis Pasteur had shown in 1848  that tartaric acid has optical activity and that this depends on molecular  asymmetry, and Jacobus H. van't Hoff and Joseph-Achille Le Bel (1847-  1930) had independently explained in 1874 how a molecule with a car�  bon atom bonded to four different groups has two mirror-image forms.  Stereochemistry deals with stereoisomers and with asymmetric synthesis.  John Cornforth (b. 1917) and Vladimir Prelog (1906-98) shared a 1975  Nobel Prize for work on stereochemistry and stereoisomerism of alka�  loids, enzymes, antibiotics, and other natural compounds.</p><p>sterilization Any surgical procedure intended to end fertility perma�  nently (see contraception). Such operations remove or interrupt the ana�  tomical pathways through which the cells involved in fertilization travel  (see reproductive system). They are relatively simple and more than 99%  effective. The operations used in humans are vasectomy in men and tubal  ligation (tying off and blocking or cutting of the fallopian tubes) in  women. Though these operations are considered permanent, the develop�  ment of microsurgery has improved the chances of reversal. Animals are  sterilized by castration in males and spaying (removal of the ovaries) in  females.</p><p>Sterkfontein Vsterk-fon-.tanX One of three neighbouring South African  sites (the others being Kromdraai and Swartkrans) at which the remains  of fossil hominids have been found. The fossils found include those of  Australopithecus africanus, A. robustus (see Australopithecus), and Homo  erectus. In 1996 researchers uncovered the most complete australopithe-  cine fossil skeleton since Lucy, that of an A. africanus individual with a  humanlike pelvis but with limb proportions similar to those of a modem  chimpanzee. At Makapansgat, 150 mi (240 km) to the north, the remains  of about 40 individuals of A. africanus have been found.</p><p>Sterling, Bruce (b.

A principal pro�  ponent of cyberpunk, science fiction dealing with harsh future urban soci�  eties dominated by computer technology, he edited Mirrorshades: The  Cyberpunk Anthology (1986) and published novels such as Schismatrix  (1985), Islands in the Net (1988), The Difference Engine (1990; with Wil�  liam Gibson), and Distraction (1999).</p><p>Stern Vshtem\ German weekly newsmagazine. Founded in 1948, it  quickly became known for its outstanding photography and its blend of  light and serious material. The magazine�s lively treatment of many top�  ics helped it achieve wide popularity in the 20th century. With a weekly  circulation of roughly one million. Stern features pictorial essays, celeb�  rity profiles, interviews, and other material and combines provocative  photographs of violence and sexual imagery with conventional pictures  of current events.

He first  performed with the San Francisco Symphony in 1936, and he made his  New York City debut at age 17. After World War II, he began to tour  extensively (including the Soviet Union in 1956). In 1960 he formed a  famous trio with pianist Eugene Istomin (b. 1925) and cellist Leonard</p><p>Rose (1918-84). He was instrumental in saving Carnegie Hall from demo�  lition, helped establish the National Endowment for the Arts, and was a  key presence in the musical life of Israel.</p><p>Sternberg, Josef von orig.

Turning his  parishes over to a curate, he began to  write Tristram Shandy (1759-67), an  experimental novel issued in nine  parts in which the story is subordi�  nate to its narrator�s free associations  and digressions. It is considered one  of the most important ancestors of  psychological and stream of con�  sciousness fiction. Long afflicted with  tuberculosis, Sterne fled the damp air  of England and undertook the trav�  els that inspired his unfinished Sen�  timental Journey Through France  and Italy (1768), a comic novel that  defies conventional expectations of a travel book.</p><p>steroid Any of a class of natural or synthetic organic compounds with  a molecular core, or nucleus, of 17 carbon atoms in a characteristic three-  dimensional arrangement of four rings. The configuration of the nucleus,  the nature of the groups attached to it, and their positions distinguish dif�  ferent steroids. Hundreds have been found in plants and animals and  thousands more synthesized or made by modifying natural steroids. Ste�  roids are important in biology, chemistry, and medicine. Examples include  many hormones (including the sex hormones), bile acids, sterols (includ�  ing cholesterol), and oral contraceptives (see contraception).

Both of his parents were  actors, and Stevens was the stage manager of his father�s company until  1921, when he went to Hollywood to become a cameraman. He photo�  graphed many of Laurel and Hardy�s (see Laurel, Stan; and Hardy, Oliver)  comedies before turning to directing in 1933. Noted for his brilliant cam�  era techniques, careful craftsmanship, and a romanticized view of life, he  achieved fame with Alice Adams (1935) and Swing Time (1936). His later  films include Woman of the Year (1942), I Remember Mama (1948), A  Place in the Sun (1951, Academy Award), the classic western Shane  (1953), and Giant (1956, Academy Award).</p><p>Stevens, John (b. 1749, New York, N.Y.�d. March 6, 1838, Hobo�  ken, N.J., U.S.) U.S. lawyer, engineer, and inventor. He served as a colo�  nel in the American Revolution. To protect his boiler and engine designs,  he submitted his outline for a patent law; the resulting Patent Law of 1790  formed the basis of the U.S. patent system. In 1802 he became the first  person to employ a powered screw to propel a ship. In 1809 his steam�  ship Phoenix became the world�s first seagoing steamboat. In Philadel�  phia in 1811 he inaugurated the world�s first steam-ferry service. In 1825  he built the first American steam locomotive. He developed his New Jer�  sey estate into the city of Hoboken. He was the father of Robert L. Stevens.  Another son, Edwin Augustus Stevens (1795-1868), was the inventor of  the Stevens plow and a pioneer builder of ironclad warships and estab�  lished the Stevens Institute of Technology by a bequest. A third son, John  Cox Stevens (1785-1857), headed the group that sent the yacht America  to Britain, where it won the race that established the America's Cup.</p><p>Stevens, John Paul (b. April 20, 1920, Chicago, Ill., U.S.) U.S. jurist.  He studied law at Northwestern University and clerked at the Supreme  Court of the United States before joining a Chicago law firm, where he  specialized in antitrust law while also teaching and serving on various  public commissions. He was appointed to the U.S. Circuit Court of  Appeals (1970) by Pres. Richard Nixon and to the Supreme Court by Pres.  Gerald Ford (1975). Though initially perceived as a conservative, he  proved to be a moderate liberal; indeed, as the court became more con�  servative in the 1980s and early �90s, after appointments by Pres. Ronald  Reagan and Pres. George Bush, Stevens became perhaps the court�s most  liberal member.</p><p>Stevens, Robert Livingston (b. Oct. 18, 1787, Hoboken, N.J.,  U.S.�d. April 20, 1856, Hoboken) U.S. engineer and ship designer. The  son of John Stevens, he tested the first steamboat to use screw propellers.  He designed the railway T-rail in 1830, and later the railroad spike. He  found that rails laid on wooden ties, with crushed stone or gravel beneath,  provided a roadbed superior to any known before; his construction  remains in universal use.</p><p>Stevens, Thaddeus (b. April 4, 1792, Danville, Vt., U.S.�d. Aug.  11, 1868, Washington, D.C.) U.S. politician. He practiced law in Penn�  sylvania, defending fugitive slaves without fee. In the U.S. House of Rep�  resentatives (1849-53,1859-68), he opposed the extension of slavery into  the western territories. After the American Civil War, as a leader of the  Radical Republicans, he demanded strict conditions for readmission of the  seceded states. He helped establish the Freedmen's Bureau and secured pas�  sage of the 14th Amendment to the Constitution. He opposed the mod�  erate Reconstruction policies of Pres. Andrew Johnson and introduced the  resolution for his impeachment.</p><p>Stevens, Wallace (b. Oct. 2, 1879, Reading, Pa., U.S.�d. Aug. 2,  1955, Hartford, Conn.) U.S. poet. Stevens practiced law in New York City  before joining an insurance firm in Hartford in 1916; he rose to vice  president, a position he held until his death. His poems began appearing  in literary magazines in 1914. In Harmonium (1923), his first and most  verbally brilliant book, he introduced the theme that occupied his creative  lifetime and unified his thought: the relationship between imagination and</p><p>reality. His later poetry, in collec�  tions such as Ideas of Order (1936),</p><p>The Man with the Blue Guitar  (1937), and The Auroras of Autumn  (1950), continued to explore this  theme with greater depth and rigour.</p><p>Not until his late years was he widely  read or recognized as a major poet by  more than a few; he received a  Pulitzer Prize only with his Col�  lected Poems in 1955.

He traveled fre�  quently, partly in search of better climates for his tuberculosis, which  would eventually cause his death at age 44. He became known for  accounts such as Travels with a Donkey in the Cevennes (1879) and essays  in periodicals, first collected in Virginibus Puerisque (1881). His  immensely popular novels Treasure Island (1883), Kidnapped { 1886), and  Dr. Jekyll and Mr. Hyde (1886), and The Master of Ballantrae (1889) were  written over the course of a few years. A Child�s Garden of Verses (1885)  is one of the most influential children�s works of the 19th century. In his  last years he lived in Samoa and produced works moving toward a new  maturity, including the story �The Beach of Falesa� (1892) and the novel  Weir of Hermiston (1896), his unfinished masterpiece.</p><p>Stevin Vsta-vin\, Simon (b. 1548, Bruges, Flanders�d. 1620, The  Hague, Holland) Flemish mathematician. In 1585 Stevin published a  small pamphlet, La Thiende (�The Tenth�), in which he presented an  account of decimal fractions and their daily use.

There she gave a start to many  young actors and playwrights, including Bette Midler and Sam Shepard.  Stewart became known as the mother of Off-Off-Broadway theatre. A  European tour in 1965 made La Mama a mecca for European avant-garde  directors.

Stewart began writing while  working as a college professor. In his mystery novels, he created the char�  acter of Inspector John Appleby, a British detective known for his suave  humour and literary finesse. Among the best of these mysteries, all pub�  lished under the pseudonym of Michael Innes, are Lament for a Maker  (1938), The Journeying Boy (1949), and An Awkward Lie (1971).

His engag�  ing manner, however, led to quick  acceptance by the movie-going pub�  lic, and he played endearingly simple  and idealistic characters in Frank  Capra�s You Can�t Take It with You  (1938) and Mr. Smith Goes to Wash�  ington (1939). He won an Academy  Award for best actor for his perfor�  mance in The Philadelphia Story  (1940). After serving as a bomber  pilot in World War II, he starred in  It�s a Wonderful Life (1946), which  became a Christmas classic. He was  known for his portrayals of diffident  but morally resolute characters. His  many movies include Destry Rides  Again (1939), The Glenn Miller Story (1954), The Man from Laramie  (1955), Anatomy of a Murder (1959), and Alfred Hitchcock�s Rope (1948),  Rear Window (1954), The Man Who Knew Too Much (1955), and Vertigo</p><p>(1958).</p><p>Stewart, Potter (b.

After settling in  Cincinnati, Ohio, he served on the city council and as vice mayor before  his appointment to the U.S. Court of Appeals in 1954. In 1958 Pres.  Dwight D. Eisenhower appointed him to the Supreme Court of the United  States, where he served until 1981. A moderate, he wrote the majority  opinion in the Shelton v. Tucker case, which held unconstitutional the  requirement that teachers list all the associations to which they belong,  and also wrote a memorable dissent in Miranda v. Arizona, in which he  argued that the court�s decision provided too much protection to defen�  dants and undermined the ability of the police to enforce the law. He is  perhaps best remembered for summarizing the difficulty in defining  obscenity, writing in a concurring opinion that �I know it when I see it.�</p><p>Stibitz, George Robert (b.

Stibnite occurs in low-temperature hydrother�  mal veins (see hydrothermal ore deposits) and in replacement deposits. Sig�  nificant deposits have been found in China, Japan, and the U.S. (Idaho,  California, and Nevada). Stibnite is used in making matches, fireworks,  and percussion caps and was used by the ancients as a cosmetic (called  kohl) to increase the apparent size of the eye.</p><p>Stick style Style of residential design popular in the U.S. in the 1860s  and �70s, a precursor to the Shingle style. The Stick style favoured an imi�  tation half-timbered effect, with boards attached to the exterior walls in  grids suggestive of the underlying frame construction. Other characteris�  tic features included attached open stickwork verandas, projecting square  bays, steeply pitched roofs, and overhanging eaves. Angular and vertical  elements were emphasized. Though associated with Carpenter Gothic, the  Stick style made less use of gingerbread. The style also marked the begin�  ning of greater openness of the floor plan. Charles S. and Henry M.

After taking over the  factory, he moved it to New York state, first to Binghamton and then to  Syracuse. Influenced by the Arts and Crafts Movement and by visits to old  missions in the American Southwest, he introduced c. 1900 a highly origi�  nal line of sturdy oak furniture. To spread his ideas and designs, he pub�  lished the influential magazine The Craftsman (1901-16).

He owned three mansions, where his  comings and goings were announced by a cannon salute and band music,  but his lavish style and adverse economic conditions eventually bank�  rupted him.</p><p>Stieglitz \'steg-lits\, Alfred (b. Jan. 1, 1864, Hoboken, N.J., U.S.�d.</p><p>July 13, 1946, New York, N.Y.) U.S.  photographer and exhibitor of mod�  em art. He was taken to Europe by  his wealthy family to further his edu�  cation in 1881. In 1883 he aban�  doned engineering studies in Berlin  for a photographic career. Returning  to the U.S. in 1890, he made the first  successful photographs in snow, in  rain, and at night. In 1902 he  founded the Photo-Secession group  to establish photography as an art.  His own best photographs are per�  haps two series (1917-27), one of  portraits of his wife, Georgia  O'Keeffe, and the other of cloud  shapes corresponding to emotional  experiences. His photographs were  the first to be exhibited in major U.S.  museums. He also was the first to  exhibit, at his �291� gallery in New  York City, works of modem Euro�  pean and U.S. painters, five years  before the Armory Show.</p><p>V j �</p><p>&#x25BA; J \</p><p>&amp;</p><p>Alfred Stieglitz at his gallery "291" in</p><p>1934; behind him is a painting by his  wife, Georgia O'Keeffe.</p><p>IMOGEN CUNNINGHAM</p><p>Stiernhielm Vshem-.yelnA, Georg orig.

April 22, 1672, Stockholm) Swedish poet and scholar, often called �the  father of Swedish poetry.� Beginning about 1640 he was poet in atten�  dance at the court of Queen Christina. His most important work is the  allegorical, didactic epic Hercules (1658), a sermon on virtue and honour  and a fine example of late-Renaissance Classicism; it greatly influenced  the development of Swedish poetry.

He also studied public regulation, concluding that it is usually det�  rimental to consumer interests. He won the Nobel Prize in Economic  Sciences in 1982.</p><p>Stiglitz, Joseph E. (b. Feb. 9, 1943, Gary, Ind., U.S.) U.S. economist.  He received a Ph.D. (1967) from the Massachusetts Institute of Technol�  ogy and taught at several universities, including Yale, Harvard, Stanford,  and Columbia. From 1997 to 2000 he was the World Bank�s chief econo�  mist but often disagreed with the organization�s policies. Stiglitz helped  found modern development economics, and he changed how economists  think about the way markets work. His studies on asymmetric informa�  tion in the marketplace showed that the poorly informed can obtain infor�  mation from the better informed through a screening process, for example,  when insurance companies determine the risk factors of their clients. He  shared the 2001 Nobel Prize in Economic Sciences with George A. Aker-  lof and A. Michael Spence.</p><p>stigmata \stig-'ma-t9\ In Christian mysticism, bodily marks, scars, or  pains suffered in places corresponding to those of the crucified Jesus �on  the hands and feet, near the heart, and sometimes on the head (from the  crown of thorns) or shoulders and back (from carrying the cross and being  whipped). They are often presumed to accompany religious ecstasy and  are taken as signs of holiness. The first to experience stigmata was St.  Francis of Assisi (1224). Of the more than 330 persons identified with stig�  mata since the 14th century, more than 60 were canonized or beatified by  the Roman Cathouc church (see canonization).</p><p>Stijl Vstll, 'stal\, De Dutch The Style Group of Dutch artists founded  in 1917, including Theo van Doesburg  and Piet Mondrian. The group advo�  cated a utopian style: �the universal  harmony of life.� Its ideal of purity  and order in life and society as well  as art reflects the Calvinist back�  ground of its members. Through its  journal, De Stijl (1917-31), it influ�  enced painting, the decorative arts  (including furniture design), typog�  raphy, and especially architecture,  where its aesthetic found expression  at the Bauhaus and in the Interna�  tional Style.</p><p>Stikine \sti-'ken\ River River,  northwestern British Columbia,</p><p>Canada, and southeastern Alaska,</p><p>U.S. The river rises in the Stikine  Ranges of British Columbia and  flows in a wide arc west and south�  west before emptying into the Pacific  Ocean after a course of 335 mi (540 km). It served as a major access  route during the Klondike gold rush of 1896. Navigable for 168 mi (270  km), it is a chief route to the Cassiar Mountains mining region.</p><p>Still, Clyfford (b. Nov. 30, 1904, Grandin, N.D., U.S.�d. June 23,  1980, Baltimore, Md.) U.S. painter. He studied at Spokane University and  Washington State College. After experimenting with several styles, he  became involved in Abstract Expressionism and was a pioneer of very large,  monochromatic painting. His work is often characterized within the  �colour-field� subset of Abstract Expressionism. He used thickly applied,  opaque paint (impasto) in expressively modulated, jagged forms to por�  tray raw, aggressive power.</p><p>Still, William Grant (b. May 11, 1895, Woodville, Miss., U.S.�d.  Dec. 3, 1978, Los Angeles, Calif.) U.S. composer. He initially intended  to be a doctor but instead studied music at Oberlin College, learning  clarinet, oboe, and violin. He studied composition with George Chadwick  (1854-1931) and Edgard Varese. In the 1920s he worked as an arranger  for the dance-band leader Paul Whiteman and for the blues composer W.C.  Handy. Still�s early style was avant-garde {From the Black Belt, 1926),  but from c. 1930 he sought to develop a distinctive African American art  music in five symphonies (including his Afro-American Symphony, 1931),  ballets, operas, and choral and solo vocal works.</p><p>still-life painting Depiction of inanimate objects for the sake of their  qualities of form, colour, texture, composition, and sometimes allegori�  cal or symbolical significance. Still lifes were painted in ancient Greece  and Rome. In the Middle Ages they occur in the borders of illuminated  manuscripts. The modern still life emerged as an independent genre in the  Renaissance. Netherlandish still lifes often depicted skulls, candles, and  hourglasses as allegories of mortality, or flowers and fruits to symbolize  nature�s cycle. Several factors contributed to the rise of still life in the  16th�17th century: an interest in realistic representation, the rise of a  wealthy middle class that wanted artworks to decorate its homes, and  increased demand for paintings of secular subjects other than portraits in  the wake of the Reformation. Dutch and Flemish painters were the mas�  ters of still life in the 17th century. From the 18th century until the rise  of nonobjective painting after World War II, France was the centre of  still-life painting.</p><p>Stillman, James (b. June 9, 1850, Brownsville, Texas, U.S.�d. March  15, 1918, New York, N.Y.) U.S. financier and banker. He began his career  in a New York mercantile house. He became president of the National  City Bank (see Citigroup) in 1891, shortly after the Rockefeller family  obtained a controlling interest in the bank. Under his leadership the bank  prospered during the panic of 1893, more than doubling its deposits and  becoming the leading U.S. bank. In 1897 it was the only bank capable of  financing the reorganization of the Union Pacific Railroad. At his death he  left a huge personal fortune.</p><p>stilt Any of certain species of shorebirds (family Recurvirostridae) that  have long thin legs and a long slen�  der bill and inhabit warm regions  worldwide. Stilts, 14-18 in. (35-45  cm) long, live around ponds, probing  in mud and weedy shallows for crus�  taceans and other small aquatic ani�  mals. The common stilt ( Himantopus  himantopus) is variably black-and-  white with pink legs and red eyes.</p><p>Stilwell, Joseph W(arren) (b.</p><p>March 19, 1883, Palatka, Fla.,</p><p>U.S.�d.

He studied  Chinese and served in Tianjin (1926-29) and as a military attache in  Beijing (1935-39). At the outbreak of World War II, he became chief of  staff to Gen. Chiang Kai-shek and commanded Chinese armies in Burma  (1939-42). He became commander of U.S. forces in China, Burma, and  India and oversaw construction of the Ledo, or Stilwell, Road, a strategic  military link with the Burma Road. Promoted to general (1944), he com�  manded the U.S. 10th Army in the Pacific (1945-46).</p><p>Stilwell Road formerly Ledo Road Former military highway, Asia.  It was 478 mi (769 km) long and linked northeastern India with the Burma  Road. In World War II, U.S. Army engineers and Chinese troops con�  structed it to link the railheads of Ledo, India, and Mogaung, Burma.  Named for Gen.

After the Japanese occu�  pation of Manchuria (1931), he sent to Japan a diplomatic note, the con�  tents of which became known as the Stimson Doctrine, refusing to  recognize territorial changes and reaffirming U.S. treaty rights. As secre�  tary of war (1940^15), he oversaw the expansion and training of U.S.  forces in World War II. He was the chief adviser on atomic policy to  Franklin D. Roosevelt and Harry Truman and recommended use of the  atomic bomb on Hiroshima and Nagasaki.</p><p>Stimulant Any drug that excites any bodily function; usually one that  stimulates the central nervous system, inducing alertness, elevated mood,  wakefulness, increased speech and motor activity, and decreased appetite.

These  bottom-dwellers often lie partially buried in the shallows, lashing their  tail when disturbed. Large stingrays can drive their tail spines into a  wooden boat. The spines cause serious, extremely painful wounds that,  if abdominal, may be fatal.</p><p>Stirling Town and council area (pop., 2001: 86,212), south-central Scot�  land. Located on the River Forth, Stirling has evidence of early settle�  ment by the British Picts. Made a royal burgh c. 1130 and a royal residence  in 1226, it was the birthplace of James II of Scotland and site of the coro�  nations of Mary, Queen of Scots, and James VI of Scotland (later James I  of England). Two battles were fought nearby: the Battle of Stirling Bridge  (1297), where Scottish troops routed the English, and the Battle of Ban�  nockburn (1314). The town flourished until the mid-16th century and  shared with Edinburgh the privileges of a capital city. After the union of  the Scottish and English crowns in 1603, it ceased to play an important  national role. The town is now a commercial centre for an agricultural  region. The council area is a centre for electronics manufacture, and there  are also papermaking, malting, brewing, and distilling industries. Stirling  is the council area�s administrative centre and largest town.</p><p>Stirling, Sir James (Frazer) (b. April 22, 1926, Glasgow, Scot.�d.  June 25, 1992, London, Eng.) Scottish architect. He began working  (1956-63) in the New Brutalist style with his partner James Gowan (see  Brutalism). His engineering building at Leicester University (1963), with  its precise crystalline forms, brought him early fame. From 1971 he  worked with Michael Wilford. In the 1970s Stirling developed his own  brand of postmodernism that made use of complex geometric abstraction,  bold colours, and Classical elements. The Neue Staatsgalerie (1977-84)  in Stuttgart, Ger., is among his finest statements. In 1981 Stirling received  the Pritzker Architecture Prize.</p><p>Stirling, William Alexander, 1st earl of (b. c. 1576, Menstrie,  Clackmannan, Scot.�d. Feb. 12, 1640, London, Eng.) Scottish poet and  colonizer of Canada. He was a member of the court of James I, where he  wrote his sonnet sequence Aurora (1604). In 1621 he obtained a grant for  territory in North America that he named New Scotland (Nova Scotia),  despite French claims to part of the land. He offered baronetcies to Scots�  men who would sponsor settlers, but the region was not colonized until  his son established a settlement at Port Royal (Annapolis Royal). Alex�  ander was compelled to surrender the territory under the Treaty of Susa  (1629), which ended an Anglo-French conflict. Scottish settlers were  ordered to withdraw by 1631.</p><p>stoa Vsto-oV In Greek architecture, a freestanding colonnade or covered  walkway; also, a long open building with its roof supported by one or  more rows of columns parallel to its rear wall. Stoas lined marketplaces  and sanctuaries and formed places of business and public promenades.  Rooms might back onto the colonnade, and a second story was some�  times added. The Stoa of Attalus in Athens (2nd century bc), a large,  elaborate, two-story building with a row of shops at the rear, was a prime  example.</p><p>stochastic process \sto-'kas-tik\ In probability theory, a family of ran�  dom variables indexed to some other set and having the property that for  each finite subset of the index set, the collection of random variables  indexed to it has a joint probability distribution. It is one of the most  widely studied subjects in probability. Examples include Markov pro�  cesses (in which the present value of the variable depends only upon the  immediate past and not upon the whole sequence of past events), such as  stock-market fluctuations, and time series (in which temperature or rain�  fall measurements, for example, are taken at the same time each day over  several days).</p><p>stock In finance, the subscribed capital of a corporation or limited-  liability company, usually divided into shares and represented by trans�  ferable certificates. Many companies have only one class of stock, called  common stock. Common stock, as a share of ownership in the company,  entitles the holder to an interest in the company�s earnings and assets. It  carries voting rights that enable the holder to participate in the running  of the company (unless such rights are specifically withheld, as in spe�  cial classes of non voting shares). Dividends paid on common stock are  often unstable because they vary with earnings; they are also usually less</p><p>than earnings, the difference being used by the management to expand the  firm. To appeal to investors who want to be sure of receiving dividends  regularly, some companies issue preferred stock, which has a prior claim  to dividends paid by the company and, in most cases, to the company�s  assets in case of its dissolution. Preferred-stock dividends are usually set  at a fixed annual rate that must be paid before dividends are distributed  to common stockholders. See also security, stock exchange.</p><p>stock-car racing Form of automobile racing. Popular in the U.S., it  features cars that conform externally to standard U.S. commercial mod�  els and are raced usually on oval, paved tracks. The National Association  for Stock Car Auto Racing (NASCAR), founded in 1947 in Daytona  Beach, Fla., gave the sport its first formal organization. The Daytona 500  is the sport�s premier race.</p><p>stock exchange or stock market or (in continental Europe)  Bourse Organized market for the sale and purchase of securities (see  security) such as stocks and bonds. Trading is done in various ways: it may  occur on a continuous auction basis, it may involve brokers buying from  and selling to dealers in certain types of stock, or it may be conducted  through specialists in a particular stock. Some stock exchanges, such as  the New York Stock Exchange (NYSE), sell seats (the right to trade) to a  limited number of members who must meet eligibility requirements.  Stocks must likewise meet and maintain certain requirements or risk being  delisted. Stock exchanges differ from country to country in eligibility  requirements and in the degree to which the government participates in  their management. The London Stock Exchange, for example, is an inde�  pendent institution, free from government regulation. In Europe, mem�  bers of the exchanges are often appointed by government officials and  have semigovemmental status. In the U.S., stock exchanges are not  directly run by the government but are regulated by law. Technological  developments have greatly influenced the nature of trading. In a tradi�  tional full-service brokerage, a customer placed an order with a broker or  member of a stock exchange, who in turn passed it on to a specialist on  the floor of the exchange, who then concluded the transaction. By the 21st  century, increased access to the Internet and the proliferation of electronic  communications networks (ECNs) altered the investment world. Through  e-trading, the customer enters an order directly on-line, and software auto�  matically matches orders to achieve the best price available without the  intervention of specialists or market makers. In effect, the ECN is a stock  exchange for off-the-floor trading.</p><p>Stock Market Crash of 1929 Economic event in the U.S. that pre�  cipitated the Great Depression. The U.S. stock market expanded rapidly in  the late 1920s and reached a peak in August 1929, when prices began to  decline while speculation increased. On October 18 the stock market  began to fall precipitously. On the first day of real panic, October 24,  known as �Black Thursday,� a record 12,894,650 shares were traded.  Banks and investment companies bought large blocks of stock to stem the  panic, but on October 29, �Black Tuesday,� 16 million shares were traded  and prices collapsed. The crash began a 10-year economic slump that  affected all the Western industrialized countries.</p><p>stock option Contractual agreement entitling the holder to buy or sell  a share of stock at a designated price for a specified period of time,  regardless of changes in its market price during that period. The various  kinds of stock options include put and call options, which may be pur�  chased in anticipation of changes in stock prices, as a means of specu�  lation or hedging. A put gives its holder an option to sell, or put, shares to  another party at a fixed price even if the market price declines. A call  gives the holder an option to buy, or call for, shares at a fixed price even  if the market price rises. U.S. corporations often issue stock options to  executives as a form of compensation in addition to salary, on the theory  that an option is an incentive to improve the company�s business and thus  raise the value of its stock; at times such options have been far more valu�  able than the salary itself.</p><p>Stockhausen \ , shtok- I hau-z3n\ / Karlheinz (b. Aug. 22, 1928,  Modrath, near Cologne, Ger.) German composer. Orphaned during World  War II, he supported himself with odd jobs (including jazz pianist) before  entering Cologne�s State Academy for Music in 1947. After hearing Oliv�  ier Messiaen�s music at Darmstadt in 1951, he began studying with the  composer and experimenting with SERIAUSM. His early works include Kon-  trapunkte and Klavierstiicke I-IV (1952-53). He also became involved  with musique concrete , a technique using recorded sounds as raw mate�  rial; his remarkable Song of the Youths (1956) used a highly processed</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Stockholm &#x25BA; stomach I 1825</p><p>recording of a boy soprano mixed with electronic sounds. His extensions  of serialism continued in pieces such as Zeitmasse (1956) and Gruppen  (1957), and he became a leading avant-garde spokesman. His Momente  (1964) influentially applied serialism to groups of sounds rather than  single pitches, and he began incorporating aleatory (chance) elements as  well. From the late 1960s he conceived ever grander schemes, some incor�  porating literature, dance, and ritual, as in the Light series (from 1977).</p><p>Stockholm City (pop., 2000 est.: city, 750,348; urban agglom.:  1,660,700), capital of Sweden. Built on numerous islands and peninsulas  connected by old bridges and modem overpasses, Stockholm is regarded  as one of the most beautiful capitals in the world. According to tradition,  Swedish ruler Birger Jarl founded Stockholm c. 1250. In the Middle Ages  it became Sweden�s chief trade port, and in 1436 the capital. After years  of conflict between the Swedes and Danes, Gustav I Vasa liberated the  city from Danish rule in 1523. It developed rapidly in the mid-17th cen�  tury as Sweden became a great power, and it was Sweden�s cultural cen�  tre by the 18th century. It was extensively redeveloped in the 19th century.  The second largest port in Sweden (Goteborg being the first), it is the  country�s leading cultural, commercial, financial, and educational centre.</p><p>stocking frame Knitting machine invented in 1589 that produced a  stocking stitch. Knitted fabrics are constructed by the interlocking of a  series of loops made from one or more yarns, with each row of loops  caught into the previous row; the stocking frame allowed production of a  complete row of loops at one time. The modern knitting industry, with its  highly sophisticated machinery, has grown from this simple device.</p><p>Stockport City and metropolitan borough (pop., 2001: 284,544), north�  western England. First chartered in 1220, the original settlement was built  in a gorge where the Rivers Tame and Goyt meet to form the River Mer�  sey; the modern town has spread over higher ground. Cotton spinning was  important in the 19th century; in the 20th century diversification brought  electronics and heavy engineering industries. Part of the metropolitan area  of Greater Manchester, the metropolitan borough includes, in addition to  Stockport proper, the urban area of Cheadle, the towns of Bramhall, Rom-  iley, and Marple, and areas of open countryside.</p><p>Stockton City (pop., 2000: 243,771), central California, U.S. Located  on the San Joaquin River, Stockton is connected to San Francisco Bay by  the San Joaquin�s 78-mi (126-km) deepwater channel; it is one of the  state�s two inland ports. Stockton was founded in 1847 and grew rapidly  as a miners� supply point during the 1849 gold rush. With the introduc�  tion of irrigation and the arrival of the railroad, it grew as a market for  farm produce and wines. The completion of the channel in 1933 made it  a major port as well as a supply depot for U.S. Pacific military operations.</p><p>Stockton, Robert F(ield) (b. Aug. 20, 1795, Princeton, N.J., U.S.�d.  Oct. 7,1866, Princeton) U.S. naval officer. He joined the U.S. navy and rose  to the rank of commander (1838). When the Mexican War broke out, he  took command of U.S. land and naval forces in present-day California and  proceeded to capture Los Angeles, a Mexican stronghold, on Aug. 13,  1846. Four days later, he set up a civil government and formally annexed  California to the U.S., naming himself governor. Along with Col. Stephen  Kearny and his troops he defeated an uprising by native Mexicans and  ceded the entire province to the U.S. In 1850 he resigned from the navy and  was elected to the U.S. Senate. Stockton, Calif., is named in his honour.</p><p>stoichiometry \,st6i-ke-'a-m9-tre\ Determination of the proportions  (by weight or number of molecules) in which elements or compounds react  with one another. The rules for determining stoichiometric relationships  are based on the laws of conservation (see conservation law) of mass and  energy and the law of combining weights (see equivalent weight) or vol�  umes. The tools used are chemical formulas, chemical equations, atomic  weights, and molecular weights or formula weights.</p><p>Stoicism Vsto-s-.si-zonA School of philosophy in Greco-Roman antiq�  uity. Inspired by the teaching of Socrates and Diogenes of Sinope, Stoicism  was founded at Athens by Zeno of Citium c. 300 bc and was influential  throughout the Greco-Roman world until at least ad 200. It stressed duty  and held that, through reason, mankind can come to regard the universe  as governed by fate and, despite appearances, as fundamentally rational,  and that, in regulating one�s life, one can emulate the grandeur of the calm  and order of the universe by learning to accept events with a stem and  tranquil mind and to achieve a lofty moral worth. Its teachings have been  transmitted to later generations largely through the surviving books of  Cicero and the Roman Stoics Seneca, Epictetus, and Marcus Aurelius.</p><p>Stoker, Bram orig. Abraham Stoker (b. Nov. 8, 1847, Dublin,  Ire.�d. April 20, 1912, London, Eng.) Irish writer. Though bedridden  until he was seven years old, Stoker later became an outstanding athlete.  He was in the civil service for 10 years and the manager of actor Henry  Irving for 27 years, writing letters for his employer and accompanying  him on tours. During this period he began writing fiction; his masterpiece  was the immensely successful gothic novel Dracula (1897). Derived from  vampire legends, the tale became the basis for a whole genre of literature  and film. None of his other works, including The Lair of the White Worm  (1911), approached its popularity or quality.</p><p>Stokes, William (b. Oct. 1, 1804, Dublin, Ire.�d. Jan. 10, 1878,  Howth, near Dublin) Irish physician. He received his M.D. from the Uni�  versity of Edinburgh and returned to Dublin, where he encouraged stu�  dents to work, under faculty supervision, in hospital wards and to acquire  a general as well as a medical education. He succeeded his father as  Regius Professor of Physic at the University of Dublin. His publications  included A Treatise on the Diagnosis and Treatment of Diseases of the  Chest (1837), The Diseases of the Heart and Aorta (1854), and one of the  first English works on the stethoscope.</p><p>Stokowski, Leopold (Anthony) orig. Antoni Stanislaw Bole-  slawawicz Stokowski (b. April 18, 1882, London, Eng.�d. Sept.  13, 1977, Nether Wallop, Hampshire) British-bom U.S. conductor and  organist. He studied at the Royal College of Music and the University of  Oxford. After holding organist positions and conducting a handful of con�  certs, he became conductor of the Cincinnati Symphony (1909-12), with  great success. From there he moved to the Philadelphia Orchestra, and in  the years 1912-38 he made it a world-class ensemble, creating the lush  �Philadelphia sound.� He programmed much contemporary music, and he  grasped very early the importance of recording. He made three films with  the Philadelphia Orchestra, including Walt Disney�s Fantasia (1940), and  he used his fame to help foster fledgling music organizations, including the  American Symphony Orchestra, which he formed in 1962.

Sept. 18, 1911, Kiev, Ukraine, Russian Empire)  Russian politician. Appointed governor of the provinces of Grodno (1902)  and Saratov (1903), he improved the welfare of the peasants while also  subduing their rebellions. He gained the favour of Tsar Nicholas II and  was appointed minister of the interior and prime minister in 1906. He ini�  tiated agrarian reforms that gave the peasants greater freedom to choose  representatives to the zemstvo councils and to acquire land, which he  believed would create a loyal and conservative class of farmers. His  repressive measures against rebels and terrorists earned him the enmity  of liberals. He dissolved the Duma when it opposed his reforms, but he  later won support from moderates. He was assassinated by a revolution�  ary in 1911.</p><p>stoma or stomate Any of the microscopic openings or pores in the  epidermis of leaves and young stems. They are generally more numerous  on the undersides of leaves. They provide for the exchange of gases  between the outside air and the interconnecting air canals within the leaf.  A stoma opens and closes in response to turgor pressure within its two  surrounding guard cells. Because the inner wall of each of these sausage-  or bean-shaped cells is thicker than the outer wall, when they fill with  water and become turgid they balloon outward, enlarging the stoma. A  drop in carbon-dioxide levels to lower than normal also causes the guard  cells to become turgid. Guard cells control excessive water loss from the  plant, closing on hot, dry, or windy days and opening when conditions are  more favorable.</p><p>stomach Digestive sac in the left upper abdominal cavity, which expands  or contracts with the amount of food in it. It has four regions: the cardia  leads down from the esophagus; the fundus curves above it; the body is  the largest part; and the antrum narrows to join the duodenum at the pyloric  valve. Iron and very fat-soluble substances (e.g., alcohol, some drugs) are  absorbed in the stomach.

Surgery is the only  method for treating stomach cancer, although radiation therapy or chemo�  therapy may be used in conjunction with surgery or to relieve symptoms.</p><p>stone In building construction, rock cut into blocks and slabs or broken  into pieces. It comes as hard as granite and as soft as limestone or sand�  stone. Where available, stone has generally been the preferred material  for monumental structures. Its advantages are durability, adaptability to  sculpting, and the fact that it can be used in its natural state. But it is dif�  ficult to quarry, transport, and cut, and its weakness in tension limits its  use. The simplest stonework is rubble, roughly broken stones bound in  mortar. Ashlar work consists of regularly cut blocks with squared edges.  Building stone is quarried by sawing if it is soft, and split apart with  wedges or by blasting if hard. Many devices are used to shape and dress  stone, from handheld tools to circular saws, surfacing machines, and  lathes. Some stones are strong enough to act as monolithic (one-piece)  supports and beams; and in some styles (e.g., ancient Egyptian temples)  stone slabs are employed even for roofing, supported by many closely  spaced columns. Before the arch, builders were handicapped by the ten�  dency of stone to break under its own weight. But stone in compression  has great strength, and the Romans built huge stone bridges and aque�  ducts. Though stone has generally been abandoned for structural use in  the 20th century, it is widely used as a thin, nonbearing surface cladding.  See also masonry.</p><p>Stone, Edward Durell (b.

They fly</p><p>by alternately flapping and soaring, with neck outstretched and legs trail�  ing. Most species are diurnal, feeding on small animals in shallow water  and fields; some eat carrion. Usually found in flocks, storks pair off dur�  ing the breeding season, and both parents incubate the eggs. Typical storks  have a straight or nearly straight bill; the four species of wood stork have  a curved bill.

Though he made other instruments  (including harps, lutes, mandolins, and guitars), few survive, and after  1680 he concentrated on violins. Moving away from the Amati style, he  developed (c. 1690) the �long Strad.� The Stradivari method of violin  making created a standard for subsequent times; he devised the modem  form of the violin bridge and set the proportions of the modem violin,  with its shallower body that yields a more powerful and penetrating tone  than earlier violins.

As lord  president of the north (1628-33), he quelled defiance to the crown. As  lord deputy of Ireland (1633-39), he consolidated the royal authority,  extended English settlement, reformed the administration, and increased  revenues for the crown. He was recalled to command Charles�s army  against a Scottish revolt, but the costly war was opposed by the Long Par�  liament; as a target representing the king�s authority, he was impeached  by the Parliament in 1640. Strafford was accused of subverting the laws  (he had offered to bring over the Irish army to subdue the king�s oppo�  nents in England); when it looked as though he might be acquitted, John  Pym, the leader of the House of Commons, had a bill of attainder passed  that condemned Strafford to death. Strafford released the king from his  promise of protection, and Charles gave his consent to the bill.

At age seven he immi�  grated to New York City with his family. After acting lessons with teach�  ers who had studied under Konstantin Stanislavsky, he became an actor  and stage manager with the Theatre Guild. In 1931 he cofounded the  Group Theatre, where he directed brilliant experimental plays such as Men  in White (1933). After working in Hollywood (1941-48), he returned to  New York City to become artistic director of the Actors Studio, where he  expanded Stanislavsky�s teachings to further develop method acting, in  which actors use their own emotional memory for the purpose of dra�  matic motivation. He trained actors such as Marlon Brando, Marilyn Mon�  roe, Dustin Hoffman, Geraldine Page, and Julie Harris.</p><p>Strasbourg \'stras-,burg\ German Strassburg \'shtras-,burk\ City  (pop., 1999: 264,115), eastern France. Located on the Franco-German  border, Strasbourg was originally a Celtic village; it became a garrison  under the Romans. The Franks captured it in the 5th century, and in 842  the Oath of Strasbourg, uniting the western and eastern Franks, was con�  cluded there. It became a free city within the Holy Roman Empire in 1262.  It was seized by the French in 1681 and captured by Germany in the  Franco-Prussian War (1870-71). It reverted to France after World War I  but was occupied by Germany again during World War II, when it suf�  fered considerable damage. A major river port and industrial centre, it is  the seat of the Council of Europe and an international communications  centre. Notable buildings include the restored medieval cathedral with its  14th-century astronomical clock.

Gregor became the  party�s leader in the north and built a mass movement with the help of  Otto and the young Joseph Goebbels, appealing to the lower middle classes  and workers by advocating a socialism couched in nationalist and racist  terminology. Otto resigned in 1930, disillusioned by Adolf Hitler�s non�  socialist goals. Gregor became head of the Nazi political organization,  second only to Hitler in power, but he came to share his brother�s disil�  lusionment and resigned in 1932.

The first round of negotiations began in 1969 and  resulted in a treaty regulating antiballistic missiles and freezing the number  of intercontinental ballistic missiles and submarine-launched ballistic mis�  siles. It was signed by Leonid Brezhnev and Richard Nixon in 1972. A sec�  ond round of talks (1972-79), known as SALT II, addressed the  asymmetry between the two sides� strategic forces and ended with an  agreement to limit strategic launchers (see MIRV). Signed by Brezhnev  and Jimmy Carter, it was never formally ratified by the U.S. Senate, though  its terms were observed by both sides. Subsequent negotiations took the  name Strategic Arms Reduction Talks (START). See also intermediate-range  nuclear weapons; Nuclear Test-Ban Treaty.</p><p>Strategic Arms Reduction Talks (START) Negotiations between  the U.S. and the Soviet Union aimed at reducing those countries� nuclear</p><p>arsenals and delivery systems. Two sets of negotiations (1982-83, 1985-  91) concluded in an agreement signed by George Bush and Mikhail Gor�  bachev that committed the Soviet Union to a reduction from 11,000 to  8,000 nuclear weapons and the U.S. to a reduction from 12,000 to 10,000.  After the Soviet Union�s collapse (1991), a supplementary agreement  (1992) obligated Ukraine, Belarus, and Kazakhstan to destroy the nuclear  weapons on their soil or to give them to Russia. Subsequent U.S. efforts  to develop an antimissile defense system threatened new complications  for the arms control regime. See also Strategic Arms Limitation Talks.</p><p>Strategic Defense Initiative (SDI) also called Star Wars Pro�  posed U.S. strategic defense system against nuclear attacks. Announced  as a 20-year, $20 billion effort by Pres. Ronald Reagan in 1983, SDI was  intended to defend the U.S. from a full-fledged Soviet attack by inter�  cepting ICBMs in flight. The interception was to be effected by technol�  ogy not yet developed, including space- and ground-based laser stations  and air- and ground-based missiles. The space component of SDI led to  its being derisively dubbed �Star Wars� after the popular film. Though the  program was roundly criticized by opposition politicians and arms-control  advocates as unworkable and as a dangerous violation of the Antiballis�  tic Missile (ABM) Treaty of 1972, Congress granted initial funding for  it. Early development efforts were largely unsuccessful, and with the fall  of the Soviet Union in 1991 the concept lost urgency. During the Bush  and Clinton administrations, ballistic missile defense was scaled back to  focus on protecting the U.S. from limited attack by a �rogue� state or a  single accidentally launched missile. In 2002 the U.S. withdrew from the  ABM treaty to begin active testing of a limited antimissile program.

In the 5th century bc they  gained political influence, in part because they were elected and could be  reelected, thus were able to entrench themselves in office. In the Hellenis�  tic Age they were the supreme magistrates in most federations and leagues.

In contrast to tactics, strategy�s components include a  long-range view, the preparation of resources, and planning for the use of  those resources before, during, and after an action. The term has expanded  far beyond its original military meaning. As society and warfare have  steadily grown more complex, military and nonmilitary factors have  become more and more inseparable in the conduct of war and in programs  designed to secure peace. In the 20th century, the term grand strategy,  meaning the art of employing all the resources of a nation or coalition of  nations to achieve the objects of war (and peace), steadily became more  popular in the literature of warfare and statecraft.</p><p>Stratemeyer \ , stra-t3- 1 ml-9r\ / Edward (b.

The family originated  in Bavaria, and the patriarch, Lazarus Straus, immigrated to the U.S. in  1852, followed by his wife and three sons: Isidor (1845-1912), Nathan  (1848-1931), and Oscar Solomon (1850-1926). They established a mer�  chandising firm that allowed them to gain an interest in Macy and Co.,  which led to complete ownership in 1896. Isidor established the depart�  ment store chain of Abraham &amp; Straus, served briefly in the U.S. Con�  gress, and engaged in philanthropic works; he and his wife perished  aboard the Titanic after giving Mrs. Straus�s place in a lifeboat to their  maid. Nathan was noted for his philanthropy; he distributed food and coal  in New York and supplied pasteurized milk to children in 36 cities dur�  ing the 1892 depression, built the first tuberculosis preventorium for chil�  dren (1909), and provided food for New York�s poor during the harsh  winter of 1914-15. He devoted the last years of his life to public-health  work in Palestine. Oscar was appointed Secretary of Commerce and Labor  by Pres. Theodore Roosevelt, becoming the first Jewish Cabinet member  (1906-09); he also served as emissary to Ottoman Turkey and as an  adviser to Pres. Woodrow Wilson, and he was a strong advocate for the  protection of Jewish minorities in Europe.</p><p>Strauss \'shtraus\, Franz Josef (b. Sept. 6, 1915, Munich, Ger.�d.

Called up for military  service in 1939, he was captured by U.S. forces near the end of World  War II. After his release in 1945, he served as councillor to the Bavarian  Ministry of the Interior and in 1946 was appointed deputy county direc�  tor in the Schongau district by the U.S. occupation authorities. He helped  found the Bavarian Christian Social Union (CSU) in 1945 and was elected  to the Bundestag in 1949. He served as minister of defense (1956-62)  and minister of finance (1966-69). Head of the CSU from 1961, he was  the party�s unsuccessful candidate for chancellor in 1980. As premier of  Bavaria (1978-88), he pursued economic policies that made it one of  Germany�s most prosperous states.</p><p>Strauss Vshtraus,\ English Ystraus\, Johann (Baptist) (b. Oct. 25,  1825, Vienna, Austria�d. June 3, 1899, Vienna) Austrian composer. His  father, Johann Strauss the Elder, was a self-taught musician who estab�  lished a musical dynasty in Vienna. A violinist, he played in a dance  orchestra from 1819; when it split in two (1824), he took over the sec�  ond group, for which he began to write waltzes, galops, polkas, and qua�</p><p>drilles, eventually publishing more than 250 works. As bandmaster of a  local regiment, he also wrote marches, including the Rcidetzsky March.  Johann the Younger left his family in 1842 and soon surpassed his father�s  popularity and productivity, becoming known as the �Waltz King.�� By  inducing his brothers, Josef and Eduard, to take over his conducting  duties, he gained more time to compose the symphonic waltzes for which  he is best known, including The Blue Danube (1867) and Tales from the  Vienna Woods (1868). His operettas include the popular Die Fledermaus  (1874) and The Gypsy Baron (1885). Eduard�s son Johann, a conductor  and composer in Berlin, was the last of the dynasty.</p><p>Strauss, Richard (Georg) (b. June 11, 1864, Munich, Ger.�d.

After 1900 he  focused on operas; his third such  work, Salome (1903-05), was a suc-  ces de scandale. Elektra (1906-08)  marked the beginning of a produc�  tive collaboration with the poet Hugo  von Hofmannsthal, with whom  Strauss wrote his greatest operas,  including Der Rosenkavalier (1909-  10). He remained in Austria through World War II and held a music post  in the German government, but he was later cleared of wrongdoing in  connection with the Nazi regime. After many years writing lesser works,  he produced several remarkable late pieces, including Metamorphosen  (1945) and the Four Last Songs (1948).</p><p>Stravinsky, Igor (Fyodorovich) (b. June 17, 1882, Oranienbaum,  Russia�d. April 6, 1971, New York, N.Y., U.S.) Russian-bom U.S. com�  poser. Son of an operatic bass, he decided to be a composer at age 20 and  studied privately with Nikolay Rimsky-Korsakov (1902-08). His Fireworks  (1908) was heard by the impresario Sergey Diaghilev, who commissioned  Stravinsky to write the Firebird ballet (1910); its dazzling success made  him Russia�s leading young composer. The great ballet score Petrushka  (1911) followed. His next ballet, The Rite of Spring (1913), with its shift�  ing and audacious rhythms and its unresolved dissonances, was a land�  mark in music history; its Paris premiere caused an actual riot in the  theatre, and Stravinsky�s international notoriety was assured. In the early  1920s he adopted a radically different style of restrained Neoclassicism�  employing often ironic references to older music�in works such as his  Octet (1923). His major Neoclassical works include Oedipus rex (1927)  and the Symphony of Psalms (1930) and culminate in the opera The Rake�s  Progress (1951). From 1954 he employed serialism, a compositional tech�  nique. His later works include Agon (1957)�the last of his many ballets  choreographed by George Balanchine �and Requiem Canticles (1966).</p><p>straw Stalks of grasses, particularly cereal grasses such as wheat, oats,  rye, barley, and buckwheat. Used collectively, the term means stalks  aggregated into bales or piles after the drying and threshing of grain. Since  ancient times, humans have used straw as litter and fodder for cattle, as  a covering for floors, for coarse bedding, and even as clothing. It can also  be woven into baskets, hats, floor mats, and furniture coverings. Thatched  roofs consist of straw laid down approximately 1 ft (30 cm) thick and  secured by strong cords, with the fibers running in the direction to be taken  by rainwater.

Strayhorn approached jazz composer and  bandleader Duke Ellington with a composition in 1938, and he was soon  contributing arrangements and original works to Ellington�s band. His  �Take the �A� Train,� recorded in 1941, became the band�s theme song.  His work so complemented Ellington�s that it is often impossible to dis�  tinguish their respective contributions. Strayhorn made expressive ballads  his specialty and became noted for the structural and harmonic sophisti�  cation of pieces such as �Lush Life,� �Something to Live For,� �Passion  Flower,� and �Day Dream.�</p><p>streak Colour of a mineral in its powdered form, usually obtained by  rubbing the mineral on a hard, white surface (e.g., a tile of unglazed por�  celain) to yield a streak of fine powder. The streak�s colour is usually con�  stant for a given mineral, even if the mineral varies in colour as it occurs  in the field or if the streak is different from the colour of the unpowdered  mineral. Streak is diagnostically useful because it may distinguish  between mineral species that are otherwise similar in appearance.</p><p>stream of consciousness Narrative technique in nondramatic fic�  tion intended to render the flow of myriad impressions�visual, auditory,  tactile, associative, and subliminal�that impinge on an individual con�  sciousness. To represent the mind at work, a writer may incorporate  snatches of thought and grammatical constructions that do not seem coher�  ent because they are based on the free association of ideas and images.  The term was first used by William James in The Principles of Psychology  (1890). In the 20th century, writers attempting to capture the total flow  of their characters� consciousness commonly used the techniques of inte�  rior monologue, which represents a sequence of thought and feeling. Nov�  els in which stream of consciousness plays an important role include James  Joyce�s Ulysses (1922), William Faulkner�s The Sound and the Fury (1929),  and Virginia Woolf�s The Waves (1931).</p><p>stream bed or stream channel Any long, narrow, sloping depres�  sion on land that had been shaped by flowing water. Streambeds can range  in width from a few feet for a brook to several thousand feet for the larg�  est rivers.

Streambeds may be cut in bed�  rock or through sand, clay, silt, or other unconsolidated materials.</p><p>streaming Method of transmitting a media file in a continuous stream  of data that can be processed by the receiving computer before the entire  file has been completely sent. Streaming, which typically uses data com�  pression, is especially effective for downloading large multimedia files  from the Internet; it permits, for example, a video clip to begin playing  on a user�s computer as soon as it begins to be downloaded from a Web  site. Even with improved modems and connection speeds, downloading  and playing large audio and video files without the use of streaming tech�  niques still takes an inconveniently long time. To accept streaming data,  the receiving computer needs to be running a player, a program that  decompresses the incoming data and sends the resulting signals to the  display and speakers. The audio and video files may be prerecorded, but  streaming can also accommodate a live feed over the Internet.</p><p>streamline In fluid mecfianics, the path of imaginary particles suspended  in the fluid and carried along with it.

Noted as an  expert on municipal affairs and a  writer on economics, he was elected  to the Reichstag (1907) as a member  of the National Liberal Party. In  1918 he founded the German People's  Party and sought to form coalitions  with other democratic parties. As  chancellor (1923) and foreign minis�  ter (1923-29), he worked to restore  Germany�s international status, pur�  suing a conciliatory policy with the  Allied Powers. He negotiated the  Pact of Locarno, supported the repa�  rations revisions in the Dawes and  Young plans, and secured Germany�s  admission to the League of Nations.</p><p>He shared the 1926 Nobel Prize for  Peace with Aristide Briand.</p><p>stress In phonetics, an emphasis  given to a syllable of speech by mak�  ing it louder than the rest of the word. This emphasis may have no mean�  ing; for example, Czech words are regularly stressed on the first syllable.  It may, however, distinguish the meanings of similarly spelled but differ�  ently pronounced words; for example, permit is stressed on the first syl�  lable as a noun and on the second as a verb. It may also be applied to a  word to express its importance in a sentence. See also intonation.</p><p>stress In the physical sciences and engineering, the force per unit area  within materials that arises from externally applied forces, uneven heat�  ing, or permanent deformation. Normal stress refers to the stress caused  by forces that are perpendicular to a cross-section area of the material.  Shear stress arises from forces that are parallel to the plane of the cross  section. Stress is expressed as the quotient of a force divided by an area.</p><p>stress In psychology, a state of bodily or mental tension resulting from  factors that tend to alter an existent equilibrium. Stress is an unavoidable  effect of living and is an especially complex phenomenon in modem  technological society. It has been linked to coronary heart disease, psycho�  somatic disorders, and various other mental and physical problems. Treat�  ment usually consists of a combination of counseling or psychotherapy and  medication.</p><p>strike Collective refusal by employees to work under the conditions set  by employers. Strikes may arise from disputes over wages and working  conditions. They may also be conducted in sympathy with other striking  workers, or for purely political goals. Many strikes are organized by  labour unions; strikes not authorized by the union (wildcat strikes) may  be directed against union leadership as well as the employer. The right to  strike is granted in principle to workers in nearly all industrialized coun�  tries, and its use has paralleled the rise of labour unions since the 19th  century. Most strikes are intended to inflict a cost to employers for fail�  ure to meet specific demands. Among Japanese unions, strikes are not  intended to halt production for long periods of time and are more akin to  demonstrations. In western Europe and elsewhere, workers have carried  out general strikes aimed at winning changes in the political system rather  than concessions from employers. The decision to call a strike does not  come easily, because union workers risk a loss of income for long peri�  ods of time. They also risk the permanent loss of their jobs, especially  when replacement workers hired to continue operations during the strike  stay on as permanent employees. See also boycott; lockout.</p><p>strike In geology, the direction of the line formed by the intersection of  a fault, bed, or other planar feature and a horizontal plane. Strike indi�  cates the orientation of planar structural features such as faults, beds,  joints, and folds.</p><p>Strindberg Ystrin- I ber y ,\ English Vstrind-.bsrgV (Johan) August (b.  Jan. 22,1849, Stockholm, Swed.�d.</p><p>May 14, 1912, Stockholm) Swedish  playwright and novelist. While  working as a journalist, he wrote the  historical drama Master 0/o/(1872);  though rejected by the national the�  atre and not produced until 1890, it  is now considered the first modem  Swedish drama. He won fame with  his novel The Red Room (1879),  which satirized the Stockholm art  world. His unhappy life included  three marriages and episodes of  mental instability. In his most cre�  ative period he moved restlessly  around Europe for six years, writing  his three major plays: The Father  (1887), Miss Julie (1888), and The  Creditors (1890). These iconoclastic  works portrayed the battle of the  sexes using a combination of dra�  matic naturalism and psychology.</p><p>During this period he also wrote three novels. After a mental breakdown  he experienced a religious conversion that inspired symbolic dramas such  as The Dance of Death (1901), A Dream Play (1902), and five �chamber  plays,� including The Ghost Sonata (1907).</p><p>string quartet Ensemble consisting of two violins, viola, and cello, or  a work written for such an ensemble. Since c. 1775 such works have been  perhaps the predominant genre of chamber music. It was principally devel�  oped (if not quite invented) by Joseph Haydn, who wrote some 70 quar�  tets between 1757 and 1803. Wolfgang Amadeus Mozart, Ludwig van  Beethoven, Franz Schubert, Bela Bartok, and Dmitry Shostakovich are the  preeminent subsequent quartet composers. Works called string quartets  have traditionally observed the four-movement design of the sonata and  symphony. Like most chamber music genres, quartet music was tradition�  ally intended primarily for the private enjoyment of amateur musicians  rather than for public performance.</p><p>string theory Any of a number of theories in particle physics that treat  elementary particles (see subatomic particle) as infinitesimal one�  dimensional �stringlike� objects rather than dimensionless points in space-  time. Different vibrations of the strings correspond to different particles.  Introduced in the early 1970s in attempts to describe the strong force,  string theories became popular in the 1980s when it was shown that they  might provide a fully self-consistent quantum field theory that could  describe gravitation as well as the weak, strong, and electromagnetic forces.  The development of a unified quantum field theory is a major goal in  theoretical particle physics, but inclusion of gravity usually leads to dif�  ficult problems with infinite quantities in the calculations. The most self-  consistent string theories propose 11 dimensions; 4 correspond to the 3  ordinary spatial dimensions and time, while the rest are curled up and not  perceptible.</p><p>stringed instrument Any musical instrument that produces sound by  the vibrations of strings. The strings may be of gut, metal, fibre, or plas�  tic, and may be plucked, bowed, or struck. The orchestral stringed instru�  ments include the violin, viola, cello, double bass, and harp. Keyboard  stringed instruments include the clavichord, harpsichord, piano, and vir�  ginal. See also Aeolian harp; balalaika; dulcimer; guitar; kithara; koto; lute;  lyre; mandolin; pipa; sitar; c 0d; ukulele; viol; zither.</p><p>strip mining Technique for the surface mining of coal by removing the  soil and rock overburden above a seam and extracting the exposed min�  eral. The method is used to best advantage where the coal seam is thin  and not deeply buried. (Thicker and deeper seams would be extracted by  open-pit or underground mining.) Strip mining is most economical where  flat terrain and horizontal seams permit a large area to be stripped. Where  deposits occur in rolling or mountainous terrain, a contour method is used  that creates a shelf with a slope on one side and an almost vertical wall</p><p>Strindberg, lithograph by Edvard  Munch, 1896</p><p>COURTESY OF THE MUNCH-MUSEET, OSLO; PHOTOGRAPH,  O.

Military leader and president of Paraguay (1954-89). The son of a Ger�  man immigrant, Stroessner joined the army in 1932 and rose to become  commander in chief in 1951. He deposed Pres. Federico Chavez (b.  1881?�d. 1978) and was the sole candidate in the 1954 presidential elec�  tions. He stabilized the currency, moderated inflation, and provided some  new schools and public health facilities, but he spent half the national  income on the military establishment in order to preserve his authority  and harshly suppressed his political opponents. After his election to an  eighth successive term, he was deposed in a coup d�etat and went into  exile.</p><p>Strogonov Vstro-go-noA school School of icon painting named for its  original patrons, the Stroganov fam�  ily, that flourished in Russia in the  late 16th and 17th century. The art�  ists perfected their work in the ser�  vice of the tsar in Moscow. The  paintings, designed for private use,  were produced in a muted colour  range dominated by golden browns  with gold and silver linear high�  lights. Small and exquisitely detailed  and embellished with frames and  halos of beaten gold and silver, they  represent the last vital stage of Rus�  sian medieval painting before the  westernization of Russian art at the  end of the 17th century.</p><p>Stroheim \'shtro- l him,\ English  \'stro-,hIm\, Erich von orig.

It was  followed by The Merry Widow  (1925), The Wedding March (1928),  and Queen Kelly (1928). His  extravagance and demand for artistic  control scuttled his directing career,  and he returned to acting, notably in  Grand Illusion (1937) and Sunset Boulevard (1950).</p><p>stroke or cerebrovascular accident (CVA) Sudden impairment  of brain function due to hypoxia, which may cause death of brain tissue.  Hypertension, atherosclerosis, smoking, high cholesterol, diabetes, old age,  atrial fibrillation, and genetic defects are risk factors. Strokes due to throm�  bosis (the most common cause), embolism, or arterial spasm, which cause</p><p>ischemia (reduced blood supply), must be distinguished from those due  to hemorrhage (bleeding), which are usually severe and often fatal.  Depending on its site in the brain, a stroke�s effects may include aphasia,  ataxia, local paralysis, and/or disorders of one or more senses. A massive  stroke can produce one-sided paralysis, inability to speak, coma, or death  within hours or days. Anticoagulants can arrest strokes caused by clots  but worsen those caused by bleeding. If the cause is closure of the major  artery to the brain, surgery may clear or bypass the obstruction. Reha�  bilitation and speech therapy should begin within two days to retain and  restore as much function as possible, since survivors may live many more  years. Transient ischemic attacks (�mini strokes�), with short-term loss of  function, result from blockage of blood flow to small areas. They tend to  recur and may worsen, leading to multi-infarct dementia or stroke.</p><p>stromatolite \stro- , ma-t 3 l-,It\ Layered deposit, mainly of limestone,  formed by the growth of blue-green algae (see cyanobacteria). These struc�  tures are usually characterized by thin, alternating light and dark layers  that may be flat, hummocky, or dome-shaped. Stromatolites were com�  mon in Precambrian time (more than 543 million years ago). Some of the  first forms of life on Earth are recorded in stromatolites in rocks 3.5 bil�  lion years old. Stromatolites continue to form in certain areas today, most  abundantly in Shark Bay in western Australia.</p><p>Stromboli \ , stram-bo-( l )le\ Volcano, Stromboli Island, off northeastern  Sicily, Italy. One of Europe�s most active volcanoes, it is 3,038 ft (926 m)  high. Though the last serious eruption was in 1921, lava flows continu�  ously from its crater to the sea.

He served in the U.S. House  of Representatives (1847-51) and on the Pennsylvania state supreme court  (1857-68). In 1870 he was appointed to the U.S. Supreme Court by Ulysses  S. Grant. In 1871 he spoke for the majority as the court overturned the  Hepburn decision of the previous year, a reversal that allowed Congress  the power to issue paper money as legal tender, a position favoured by  Grant. Strong retired from the court in 1880.</p><p>strong force or strong nuclear force Fundamental force acting  between elementary particles of matter, mainly quarks. The strong force  binds quarks together in clusters to form protons and neutrons and heavier  short-lived particles. It holds together the atomic nucleus and underlies  interactions among all particles containing quarks. In strong interactions,  quarks exchange gluons, carriers of the strong force, which are massless  particles with one unit of intrinsic spin. Within its short range (about 10 -15  m), the strong force appears to become stronger with distance. At such  distances, the strong interaction between quarks is about 100 times greater  than the electromagnetic force.</p><p>strontium \'stran(t)-she-3m, 'stran-te-omN Chemical element, one of the  alkaline earth metals, chemical symbol Sr, atomic number 38. A soft metal,  it has a silvery lustre when freshly cut but reacts rapidly with air. In both  the metal and the compounds (in which it has valence 2), strontium  resembles calcium and barium so closely that it has few uses that the other  two elements cannot supply more cheaply. The nitrate and chlorate, very  volatile, give off brilliant crimson flames and are used in flares, fireworks,  and tracer bullets. The radioactive isotope strontium-90 (see radioactivity),  produced in nuclear explosions, is the principal health hazard in fallout;  it can replace some of the calcium in foods, concentrate in bones and teeth,  and cause radiation injury.</p><p>structural geology Scientific discipline concerned with rock defor�  mation on both small and large scales. Its scope ranges from submicro-  scopic lattice defects in crystals to fault structures and fold systems of the  Earth�s crust. Depending on the scale, the general techniques used are the  same as those used in petrology, field geology, and geophysics. Further�  more, since the processes that cause rocks to deform can rarely be  observed directly, computer models are also used.</p><p>structural system In building construction, the particular method of  assembling and constructing structural elements of a building so that they  support and transmit applied loads safely to the ground without exceed�  ing the allowable stresses in the members.

It  is based on the linguistic theories of Ferdinand de Saussure, which hold  that language is a self-contained system of signs, and the cultural theo�  ries of Claude Levi-Strauss, which hold that cultures, like languages, can  be viewed as systems of signs and analyzed in terms of the structural rela�  tions among their elements. Central to structuralism is the notion that  binary oppositions (e.g., male/female, public/private, cooked/raw) reveal  the unconscious logic or �grammar� of a system. Literary structuralism  views literary texts as systems of interrelated signs and seeks to make  explicit their hidden logic. Prominent figures in the structuralist move�  ment are Michel Foucault, Jacques Lacan, Roman Jakobson, and Roland  Barthes. Areas of study that have adopted and developed structuralist pre�  mises and methodologies include semiotics and narratology.

The  founder of the modern study of binary stars, he measured some 3,000  binaries in his survey of more than 120,000 stars. He was also among the  first to measure stellar parallax. In 1835, at the request of Tsar Nicholas I,  he went to Pulkovo to supervise construction of a new observatory,  becoming its director in 1839. His son, Otto Struve (1819-1905), served  as director of Pulkovo Observatory (1862-89); his grandson Gustav Wil�  helm Ludwig Struve (1858-1920) was director of University of Kharkov  observatory; Otto Struve was his great-grandson.</p><p>Struve \ English Vstru-ve\, Otto (b.

After his arrest and exile in 1901, he broke  with revolutionary Marxism; from 1902 to 1905 he edited the illegal but  widely read journal Osvobozhdeniy (�Liberation�), in which he called for  a constitutional monarchy. He returned to Russia in 1905, joined the Con�  stitutional Democratic Party, and edited the moderate journal Russkaya  my sly (�Russian Thought�).

The  earliest members of the family were stewards in 11th-century Brittany; in  the 12th century a member entered the service of David I (r. 1124-53) in  Scotland and received the title of steward. The 6th steward married the  daughter of King Robert I the Bruce, and in 1371 their son became King  Robert II, the first Stewart king of Scotland (r. 1371-90). His descendants  in the 15th�17th centuries included the Scottish monarchs James I, James  II, James III, James IV, Mary, Queen of Scots, and James VI (who inherited  the English throne as James I). The Stuarts (who eventually adopted the  French-influenced spelling of their name) were excluded from the English  throne after Charles I until the restoration of Charles II in 1660. He was  followed by James II, William III and Mary II, and Anne.

Robert E. Lee in the defeat of John Brown�s raid on Harpers  Ferry. In 1861 he joined the Confederate army, becoming brigadier general  of a cavalry brigade. On scouting raids he obtained information on Union  troop movements that contributed to Confederate victories at the Seven  Days� Battle and the Second Battle of Bull Run; Lee called Stuart the �eyes  of the army.� As major general, he helped win the battles of Fredericksburg  and Chancellorsville. Before the Battle of Gettysburg, he was instructed by  Lee to gather information on Union troop movements; he was delayed on  a raid and arrived after the battle had begun.

His masterly depictions of hunters and racehorses brought him  innumerable commissions. Perhaps more impressive than the single por�  traits are his pictures of informal groups of horses, such as Mares and  Foals in a Landscape (c. 1760-70). He also painted many other animals,  including lions, tigers, giraffes, monkeys, and rhinoceroses, which he was  able to observe in private menageries.

In the 1920s film stu�  dios such as Paramount and MGM acquired theatre chains to strengthen  their vertical control of the industry, and Warner Brothers, RKO, and  Twentieth Century-Fox built similar empires soon thereafter. Studio heads  exerted control over the types of movies to be made and the directors and  actors to be hired; only a few directors maintained some independent  control over their films. The studio system also developed the �star sys�  tem,� by which certain actors and actresses were groomed for stardom,  with studio executives choosing their roles, publicizing their glamorized  offscreen lives, and keeping them under control through long contracts.  The system declined after a 1948 Supreme Court decision forced the large  studios to sell their theatre chains and increasing competition from tele�  vision forced studios to limit their staffs, and by the 1960s it had effec�  tively ended.</p><p>stupa Monument erected in memory of the Buddha or a Buddhist saint,  often marking a sacred spot, com�  memorating an event, or housing a  relic.

Four tactile barbels near the toothless mouth  detect invertebrates and small fishes on the mud bottom. Sturgeon flesh and  eggs, or roe (caviar), are sold for food. The swim bladder is used in isin�  glass, a gelatin. The Baltic sturgeon (Acipenser sturio) and several other  species are endangered. The Atlantic sturgeon (A. oxyrhynchus), however,  is common along the eastern coast of North America and generally is about  10 ft (3 m) long and weighs about 500 lb (225 kg).

Initially a playwright, he wrote the Broadway hits  Strictly Dishonorable (1929) and Child of Manhattan (1931). After mov�  ing to Hollywood, he became a noted screenwriter and won an Academy  Award for The Great McGinty (1940), the first film he directed. He went  on to write and direct distinctive satirical comedies such as The Lady Eve  (1941), Sullivan�s Travels (1941), The Palm Beach Story (1941), The  Miracle of Morgan�s Creek (1944), Hail the Conquering Hero (1944), and  Unfaithfully Yours (1948), characterized by their witty dialogue, rapid  pace, and memorable minor characters.</p><p>Sturm und Drang X.shturm-unt-'draq, .sturm-ont-'draqX German  "storm and stress" German literary movement of the latter half of  the 18th century characterized by a revolt against what the writers saw  as the Enlightenment cult of rationalism and the sterile imitation of French  literature. It exalted nature, intuition, impulse, instinct, emotion, fancy,  and inborn genius as the wellsprings of literature. Influenced by Jean-  Jacques Rousseau, Johann Gottfried Herder, and others, it took its name  from the title of a play by Friedrich von Klinger (1752-1831). Dramatic  works were the movement�s most characteristic product. Its most gifted  representatives were Friedrich Schiller and Johann Wolfgang von Goethe,  whose Sorrows of Young Werther (1774) epitomizes its spirit.</p><p>Sturtevant Vstort-o-vonA, Alfred (Henry) (b.

He  received his Ph.D. from Columbia University and taught principally at  California Institute of Technology (1928-70). In 1912 he developed a  technique for mapping the location of specific genes of the chromosomes  in Drosophila. He later proved that crossing-over (the exchange of genes  between chromosomes) could be prevented in Drosophila. He was one of  the first to warn against the hazards of fallout as a consequence of nuclear  bomb testing.</p><p>Sturzo Ystiirt-soX, Luigi (b. Nov. 26, 1871, Caltagirone, Sicily�d. Aug.  8, 1959, Rome, Italy) Italian priest and political leader. Ordained a priest  in 1894, he earned a doctorate in Rome, then returned to his native Sic�  ily to help the oppressed miners and peasants. As mayor of Caltagirone  (1905-20), he built community housing and other public works. In 1919  he founded the Italian Popular Party and became its political secretary.  Refusing to support Benito Mussolini, he went into exile in 1924. He  returned in 1946, when his political movement was revived as the Chris�  tian Democratic Party. In 1952 he was appointed senator for life. He wrote  several works of Christian social philosophy, including Church and State  (1939) and Italy and the Coming World (1945).</p><p>stuttering or stammering or dysphemia \dis-'fe-me-9\ Speech  defect affecting the rhythm and fluency of speech, with involuntary rep�  etition of sounds or syllables and intermittent blocking or prolongation of  sounds, syllables, and words. Stutterers consistently have trouble with  words starting with consonants, first words in sentences, and multisylla�  ble words. Stuttering has a psychological, not a physiological, basis, tend�  ing to appear in children pressured to speak fluently in public. In earlier  times, stutterers were subjected to often torturous efforts to cure them.  Today it is known that about 80% recover without treatment, usually by  early adulthood. This probably results from increased self-esteem, accep�  tance of the problem, and consequent relaxation.

Located on the Neckar River,  Stuttgart was originally a 10th-century stud farm. It became a town in the  13th century and passed to the counts of Wurttemberg, serving as their  capital until the 19th century. The Thirty Years' War, French invasions in  the 17th century, and heavy bombing during World War II took a toll on  the city. Many historic buildings have been rebuilt, including the 13th-  century castle. It is a cultural, transportation, industrial, and publishing  centre. The University of Stuttgart was founded in 1829.</p><p>Stuyvesant Vsti-vo-sontV, Peter (b. c. 1592, Scherpenzeel, Friesland,  Neth.�d. February 1672, near New York, N.Y.) Dutch colonial governor.

An  external sty results from infection of a sebaceous gland at the edge of the  eyelid; tears flow and the eye feels tender, as if something is in it. The  sty reddens and swells. Warm compresses help it break sooner. An inter�  nal sty is caused by infection of a meibomian gland under the eyelid lin�  ing. More painful than an external sty, it usually breaks through the inner  lining of the lid when it discharges and may leave a painless cyst (cha�  lazion) at the site. See also boil.</p><p>Style Moderne See Art Deco</p><p>stylistics Aspect of literary study that emphasizes the analysis of vari�  ous elements of style (such as metaphor and diction). The ancients saw  style as the proper adornment of thought. In this view, which prevailed  throughout the Renaissance, devices of style can be catalogued and ideas  can be framed with the help of model sentences and prescribed types of  figures suited to the mode of discourse. In more recent theories, the rela�  tionship of style and the individual writer�s unique vision of reality is  emphasized.</p><p>stylolite \ , stl-b- l llt\ Sedimentary structure consisting of a series of rela�  tively small, alternating, interlocked, toothlike columns of stone; it is  common in limestone, marble, and similar rock. The individual columns  never appear singly but occur as a succession of interpenetrations that in  cross section make a zigzag suture across the face of the stone. Most  geologists believe that they are of secondary origin; that is, they result  from differential chemical solution as groundwater circulates along a part�  ing in hardened rock.</p><p>Styne, Jule orig. Julius Kerwin Stein (b. Dec. 31, 1905, London,  Eng.�d. Sept. 20, 1994, New York, N.Y., U.S.) British-born U.S. song�  writer. Bom to Ukrainian Jewish parents, he and his family settled in Chi�  cago, Ill., U.S., in 1912. His first hit song was published in 1926. In the  early 1930s he changed his name to avoid confusion with another per�  former. He moved to Hollywood, Calif., in 1937 to write film musicals.  In the 1940s he worked with lyricist Sammy Cahn, writing ballads for Frank  Sinatra, the film musical Anchors Aweigh (1945), and the Broadway musi�  cal High Button Shoes (1947). He collaborated with other lyricists on  musicals such as Gentlemen Prefer Blondes (1949), Bells Are Ringing  (1956), Gypsy (1959), and Funny Girl (1964). His songs include �Let It  Snow,� �The Party�s Over,� and �People.�</p><p>Styron, William (b. June 11, 1925, Newport News, Va., U.S.) U.S.  novelist. Educated at Duke University, Styron became part of the Ameri�  can expatriate community in Paris in the 1950s. His first novel. Lie Down  in Darkness (1951), tells of a disturbed young woman who commits sui�  cide. His fourth, the controversial Confessions of Nat Turner (1967,  Pulitzer Prize), vividly evokes the slavery era. His later work includes  Sophie�s Choice (1979), examining ramifications of the Holocaust; and  Darkness Visible (1990), a nonfiction account of his depression. His works  often treat violent themes in a rich, Faulknerian style.</p><p>Styx \'stiks\ In Greek mythology, a river of the underworld. The name  comes from a Greek word that denotes both hatred and extreme cold, and  it expresses loathing of death. In the epics of Homer, the gods swore by  the water of Styx as their most binding oath. Hesiod personified Styx as  the daughter of Oceanus and the mother of Emulation, Victory, Power,  and Might. The ancients believed that its water was poisonous and would  dissolve any vessel except one made of the hoof of a horse or an ass.</p><p>Su Song or Su Sung \'su-'suq\ (b. 1020, Fujian Province, China�d.  1101, Kaifeng) Chinese scholar and administrative and financial expert in  the imperial bureaucracy.

An  armillary clock that he built to serve as the basis of calendrical reform  was housed in a 35-ft (11-m) tower and powered by a waterwheel and  chain drive; its mechanism anticipated techniques that would not be used  in Europe for hundreds of years.</p><p>Suarez \'swa-rath\, Francisco (b. Jan. 5, 1548, Granada, Spain�d.  Sept. 25, 1617, Lisbon) Spanish theologian and philosopher. In his Meta�  physical Disputations (1597), he drew on the works of Aristotle, St. Tho�  mas Aquinas, John Duns Scotus, and Luis de Molina (1535-1600) to  discuss the free will problem and other metaphysical topics. He is widely</p><p>considered the greatest Scholastic philosopher after Aquinas (see Scho�  lasticism) and the major Jesuit theologian. His departures from Aquinas�s  positions have been considered significant enough to warrant the separate  designation of his system as Suarezianism.</p><p>Suarez, Hugo Banzer See Hugo Banzer Suarez</p><p>subatomic particle or elementary particle Any of various self-  contained units of matter or energy. Discovery of the electron in 1 897 and  of the atomic nucleus in 1911 established that the atom is actually a com�  posite of a cloud of electrons surrounding a tiny but heavy core. By the  early 1930s it was found that the nucleus is composed of even smaller  particles, called protons and neutrons. In the early 1970s it was discov�  ered that these particles are made up of several types of even more basic  units, named quarks, which, together with several types of leptons, con�  stitute the fundamental building blocks of all matter. A third major group  of subatomic particles consists of bosons, which transmit the forces of the  universe. More than 200 subatomic particles have been detected so far,  and most appear to have a corresponding antiparticle (see antimatter).</p><p>subbituminous coal Dark-brown to black coal, intermediate in rank  between lignite and bituminous coal. It contains less water and is harder  than lignite, making it easier to transport, store, and use. It has lower  heating value than bituminous coal, but its sulfur content is often low, so  that a number of coal-fired electric-power plants have switched from bitu�  minous to subbituminous coal and lignite (which also tends to have rela�  tively low sulfur). Subbituminous deposits are found in the U.S., Canada,  Brazil, Germany, Russia, Ukraine, Australia, and China.</p><p>subconscious See unconscious</p><p>subduction zone Oceanic trench area in which, according to the  theory of plate tectonics, the seafloor underthrusts an adjacent plate, drag�  ging the accumulated trench sediments downward into the Earth�s upper  mantle.

From 1901 it was the site of the U.S.-operated Subic Bay Naval  Station, the largest naval installation in the Philippines. The area suffered  heavy damage in World War II and was occupied by the Japanese in  1942-44. The base played a prominent supply and maintenance role in  the Vietnam War (1955-75). Control of the bay was transferred to the  Philippines in 1992, and it subsequently was redeveloped as a free-trade  zone and recreational and tourist destination.</p><p>sublimation In physics, the change of state of a substance from a solid  to a gas without first becoming liquid. One example is the vaporization  of frozen carbon dioxide, or dry ice, at ordinary atmospheric pressure and  temperature. The phenomenon occurs at pressures and temperatures (both  relatively low) where solid and vapour phases coexist in equilibrium. Pres�  ervation of food by freeze-drying involves sublimation of water from the  food in a frozen state under vacuum.</p><p>submachine gun Lightweight automatic small-arms weapon cham�  bered for relatively low-energy pistol cartridges and fired from the hip or  shoulder. Submachine guns usually have box-type magazines that hold  10-50 cartridges, or occasionally drums holding more rounds. A short-  range weapon, they are rarely effective at more than 200 yards (180 m).  They can fire 650 or more rounds per minute and weigh 6-10 lbs (2.5-  4.5 kg). Important types include the Thompson submachine gun, or  tommy gun (patented 1920), the British Sten gun of World War II, and  the later Israeli Uzi.</p><p>submarine Naval vessel capable of operating underwater for sustained  periods. In the 18th and 19th centuries, American inventors such as David  Bushnell (17427-1824) and Robert Fulton experimented with hand-  powered submarines. In 1898 John P. Holland (1840-1914) launched the  Holland , which had both a gasoline engine for surface locomotion and a  battery-powered electric motor for submerged cruising; it was purchased  by the U.S. government in 1900. The innovations of Simon Lake (1866�  1945) were adopted first in Europe and later in the U.S. By the eve of  World War I, all major navies had diesel-electric submarines. German  U-boats were an especially potent threat; through World War II they intro�  duced such innovations as the snorkel, which supplied fresh air to the die�  sel engine without having to surface the boat. Nuclear-powered  submarines began service with the launching of the USS Nautilus in 1954.

Subs may be armed with torpedoes, cruise  missiles, or ballistic missiles fitted with nuclear warheads. Because they  are so difficult to locate, they are of great importance in the forces of  almost all maritime states. See also depth charge; sonar; Trident missile.</p><p>submarine canyon Narrow, steep-sided underwater valley cut into a  continental slope. Submarine canyons resemble river canyons on land,  usually having steep, rocky walls. They are found along most continental  slopes. Those of the Grand Bahama Canyon, which are thought to be the  deepest, cut nearly 3 mi (5 km) deep into the continental slope. Most sub�  marine canyons extend only about 30 mi (50 km) or less, but a few are  more than 200 mi (300 km) long.</p><p>submarine fan Accumulation of land-derived sediment on the sea�  floor; a fan is shaped like the section of a cone, with its apex at the mouth  of a subbmarine canyon. The sediments consist largely of sandy material  that drops from the canyon current in successively finer layers. Subma�  rine fan valleys, with low relief and natural levees, often occur on sub�  marine fans. Several fans may coalesce laterally.</p><p>submarine fracture zone Long, narrow, and mountainous subma�  rine lineation that generally separates ocean-floor ridges differing in depth  by as much as 1 mi (1.6 km). The largest fracture zones, in the eastern  Pacific, are more than 1,000 mi (1,600 km) long and 60-125 mi (100-  200 km) wide. Numerous shorter fracture zones in the Atlantic are asso�  ciated with the Mid-Atlantic Ridge.</p><p>submarine mine In military and naval operations, a stationary explo�  sive device placed in the water and designed to destroy ships that touch  or approach it. Submarine mines have been used since the mid-19th cen�  tury. They consist of an explosive charge fitted with a device that deto�  nates the charge when a ship or submarine is nearby. Placed by vessels  called minelayers or dropped by aircraft, they are anchored to the sea floor  by a cable. Various types of submarine mines are detonated by contact,  by an approaching ship�s magnetic field, by changes in water pressure,  or by the sound of a ship�s propellers. The mine was the most effective  antisubmarine weapon in World War I. Its role was even greater in World  War II, when mines sank 1,118 Allied ships and 1,316 Axis ships. See  also LAND MINE, MINESWEEPER.</p><p>submarine plateau See oceanic plateau</p><p>submarine slump In a submarine canyon or on a continental slope, a  relatively rapid and sporadic downslope moving mass composed of sedi�  ment and organic debris that has built up slowly into an unstable or mar�  ginally stable mass. After an individual slump in a canyon, however, the  material tends to continue falling in a series of slumps until the sediment  mass attains a shallower, more stable slope. A slumping episode may also  trigger other slumps farther down the canyon.</p><p>subpoena \s3-'pe-n3\ In law, a writ commanding the person upon  whom it has been served to appear in court or before a congressional  committee, grand jury, or some other body, under a penalty for failure to  comply.

Subsidies to transportation,  housing, agriculture, mining, and other industries have been instituted on  the grounds that their preservation or expansion is in the public interest.  Subsidies to the arts, sciences, humanities, and religion also exist in many  nations where the private economy is unable to support them. Examples  of direct subsidies include payments in cash or in kind, while more-  indirect subsidies include governmental provision of goods or services at  prices below the normal market price, governmental purchase of goods  or services at prices above the market price, and tax concessions. Although  subsidies exist to promote the public welfare, they result in either higher  taxes or higher prices for consumer goods. Some subsidies, such as pro�  tective tariffs, may also encourage the preservation of inefficient produc�  ers. A subsidy is desirable only if its effects increase total benefits more  than total costs (see cost-benefit analysis).</p><p>subsistence farming Form of farming in which nearly all the crops  or livestock raised are used to maintain the farmer and his family, leav�</p><p>ing little surplus for sale or trade. Preindustrial agricultural peoples  throughout the world practiced subsistence farming. As urban centers  grew, agricultural production became more specialized and commercial  farming developed, with farmers producing a sizable surplus of certain  crops, which they traded for manufactured goods or sold for cash. Sub�  sistence farming persists today in sub-Saharan Africa and other develop�  ing areas.</p><p>subsoil Layer (stratum) of earth immediately below the surface soil,  consisting predominantly of minerals and leached materials such as iron  and aluminum compounds. Humus remains and clay accumulate in sub�  soil, but the teeming macroscopic and microscopic organisms that make  the topsoil rich with organic matter spend little time in the subsoil layer.  Below the subsoil is a layer of partially disintegrated rock, and underly�  ing bedrock. Stripping topsoil while clearing land for crop growth or  commercial development exposes the subsoil and increases the rate of  erosion of soil minerals.</p><p>substantive law See procedural law</p><p>subsurface water See groundwater</p><p>Subud \'su-biid\ Indonesian religious movement based on spontaneous  and ecstatic exercises. Founded in 1933 by Muhammad Subuh, a student  of Sufism who underwent a mystical experience in 1925, the movement  was largely confined to Indonesia until it spread to Europe and the U.S.  in the 1950s, chiefly because of the work of George Gurdjieff. The cen�  tral feature of Subud is the latihan, a group spiritual activity in which  practitioners allow the power of God to express itself through unrestrained  spontaneous activity. Unprogrammed singing, dancing, shouting, and  laughter are thought to give rise to feelings of rapture and release and to  promote psychological and physical healing.</p><p>subway Underground railway system used to transport passengers  within urban and suburban areas. The first subway line, 3.75 mi (6 km)  long, opened in London in 1863 and carried 9Vi million passengers in its  first year. The first electrified subway opened in 1890 in London (where  it is called the underground or tube). Subways opened in Budapest in 1896  (the first on the European continent), Boston in 1897, Paris in 1900 (where  it is called the metro), Berlin in 1902, New York in 1904, and later in  Madrid (1919), Tokyo (1927), and Moscow (1935). Improvements in sys�  tems built from the 1970s on (including San Francisco, Washington, D.C.,  and Los Angeles) include computer technology to run subway trains by  remote control, and refinements in track and car construction for faster,  smoother, and quieter rides.</p><p>succubus See incubus and succubus</p><p>succulent Any plant with fleshy, thick tissues adapted to water storage.  Some succulents (e.g., the cactus) store water only in the stem and have  no leaves or very small leaves; others (e.g., agaves) store water mainly in  the leaves. Most have deep or broad root systems and are native to either  deserts or regions that have a semiarid season.

He  inherited his father�s considerable estates at age 18 and became promi�  nent at court as a gallant and a gamester; he is credited with inventing  cribbage. After participating in a foiled plot to rescue the Earl of Strafford  from the Tower of London, he fled to France and is believed to have com�  mitted suicide. He wrote four plays, the best being the lively comedy The  Goblins (1638). His reputation as a poet rests on his lyrics, the best of  which are easy and natural. His masterpiece is �A Ballad upon a Wed�  ding,� written in the style and metre of the contemporary street ballad.</p><p>Sucre \'sii-kra\ Judicial capital (pop., 2001: 193,873), Bolivia. Founded  by the Spanish (c. 1539) on the site of a Charcas Indian village, it became  the capital of the Charcas territory of Upper Peru in 1561 and in 1609 the  seat of an archdiocese. Many of its colonial churches survive. It was an  early scene (1809) of the revolt against Spain. The Bolivian declaration  of independence was signed there in 1825, and it became the capital in  1839. An effort to move the capital to La Paz in 1898 precipitated a civil  war, which left the two cities sharing capital status. Sucre is also the seat  of the national supreme court. It is a growing commercial centre. The  University of San Francisco Xavier, one of the oldest universities in South  America, was founded there in 1624.</p><p>Sucre \'su-kra\ (Alcala), Antonio Jose de (b.

A close ally  of Simon Bolivar, Sucre fought in the revolutionary struggles of Venezu�  ela, Colombia, Gran Colombia (now Ecuador), Peru, and Upper Peru (now  Bolivia), defeating royalist forces throughout the region. In 1826 he set  up a Bolivian government and briefly served as president, but he soon  retired to Gran Colombia. In 1829 he was called back into service to  defend Gran Colombia against a Peruvian invasion. He was assassinated  in 1830 at age 35.

Chief cash crops are cotton, peanuts, and sesame; livestock  is also important. Major industries include food processing and cotton  ginning, and petroleum is the main export. The country is ruled by an  Islamic military regime; the head of state and government is the presi�  dent. Evidence of human habitation dates back tens of thousands of years.  From the end of the 4th millennium bc, Nubia (now northern Sudan) peri�  odically came under Egyptian rule, and it was part of the kingdom of Cush  from the 11th century bc to the 4th century ad. Christian missionaries  converted the Sudan�s three principal kingdoms during the 6th century  ad; these black Christian kingdoms coexisted with their Muslim Arab  neighbours in Egypt for centuries, until the influx of Arab immigrants  brought about their collapse in the 13th�15th centuries. Egypt had con�  quered all of the Sudan by 1874 and encouraged British interference in  the region; this aroused Muslim opposition and led to the revolt of the  MahdI, who captured Khartoum in 1885 and established a Muslim theoc�  racy in the Sudan that lasted until 1898, when his forces were defeated  by the British. The British ruled, generally in partnership with Egypt, until  the region achieved independence as The Sudan in 1956. Since then the  country has fluctuated between ineffective parliamentary government and  unstable military rule. The non-Muslim population of the south began  rebellion against the Muslim-controlled government of the north in the  early 1980s, leading to famines and the displacement of millions of  people; a peace agreement was signed in 2005. Meanwhile, fighting broke  out in 2003 between non-Arab Muslims in the Darfur region of western  Sudan and government-backed Arab militias; tens of thousands of people  were killed and hundreds of thousands were displaced.</p><p>sudden infant death syndrome (SIDS) or crib death Unex�  pected death of an apparently well infant. It occurs almost always during  sleep at night and usually at 2^f months of age. Sleeping facedown and  exposure to cigarette smoke have been implicated. It is more common in  cases of premature birth, low birth weight, and poor prenatal care. Many  cases that would once have been labeled SIDS prove to be due to suffo�  cation in bedding or overheating. Some babies who die of SIDS have been  found to have brain stem abnormalities that interfere with their response  to high levels of carbon dioxide in the blood.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Sudetenland &gt; sugarcane I 1839</p><p>Sudetenland Nsii-'da-Fn-.landN Sections of northern and western Bohe�  mia and northern Moravia around the Sudeten mountain ranges. Formerly  part of Austria, the predominantly German-speaking area was incorpo�  rated into Czechoslovakia after World War I. Discontent among the Sude�  ten Germans was exploited in the mid-1930s by the Nazi Party and its  local leader Konrad Henlein. The inflammatory situation convinced Brit�  ain and France that, to avoid war, Czechoslovakia must be persuaded to  give the region autonomy. Adolf Hitler�s demand that the region be ceded  to Germany was initially rejected, but the cession was later accomplished  by the Munich agreement. After World War II the region was restored to  Czechoslovakia, which expelled its German inhabitants and repopulated  the area with Czechs.</p><p>Sudra See Shudra</p><p>Suetonius \swe-'to-ne-9s, .su-o-'to-ne-osV Latin Gaius Suetonius  Tranquillus (b. ad 69, probably Rome�d. after 122) Roman biogra�  pher and antiquarian. Suetonius�s family was of the knightly class. His  writings include Concerning Illustrious Men, short biographies of liter�  ary figures that were the ultimate source of nearly all that is known about  the lives of eminent Roman authors. Lives of the Caesars, his other major  work, is seasoned with bits of gossip and scandal related to the first 11  emperors; it is largely responsible for the vivid picture of Roman society  and its decadent leaders that dominated historical thought until modified  in modern times by the discovery of nonliterary evidence.</p><p>Suez, Gulf of Northwestern extension of the Red Sea. It is located  between Africa and the Sinai Peninsula and is roughly 195 mi (314 km)  long and 12-20 mi (19-32 km) wide. Linked to the Mediterranean Sea  by the Suez Canal, it is an important shipping route. In the 1970s and �80s,  oil was discovered at numerous locations in the gulf.</p><p>Suez Canal Ship canal, Isthmus of Suez, Egypt. Connecting the Red  Sea with the eastern Mediterranean Sea, it extends 100 mi (160 km) from  Port Said to the Gulf of Suez and allows ships to sail directly between the  Mediterranean and the Indian Ocean. Built by the French-owned Suez  Canal Co., it was completed in 1869 after 11 years of construction. Its  ownership remained largely in French and British hands until Egypt  nationalized it in 1956, setting off an international crisis (see Suez Crisis).  It has a minimum width of 179 ft (55 m) and a depth of about 40 ft (12  m) at low tide. Though protected by international treaty, the canal has  been closed twice. The first closing was during the Suez Crisis. The canal  again was closed by the Six-D ay War (1967) and remained inoperative  until 1975. It is one of the world�s most heavily used shipping lanes.</p><p>Suez Crisis (1956) International crisis that arose when Egyptian presi�  dent Gamal Abdel Nasser nationalized the Suez Canal after Western coun�  tries withdrew promised financial aid to build the Aswan High Dam. The  French and British, who had controlling interests in the company that  owned the canal, sent troops to occupy the canal zone. Their ally Israel  seized the Sinai Peninsula. International opposition quickly forced the  French and British out, and Israel withdrew in 1957. The incident led to  the resignation of Britain�s prime minister, Anthony Eden, and was widely  perceived as heralding the end of Britain as a major international power.  Nasser�s prestige, by contrast, soared within the developing world.

There are prehistoric flint mines in the  north of the county. During Anglo-Saxon times Suffolk formed part of the  kingdom of East Anglia; the Sutton Hoo ship burial dates from this time.  Its medieval prosperity was based largely on the woolen cloth industry.  Since then, agriculture has been the major economic activity; crops  include cereals, sugar beets, and vegetables. The Suffolk town of New�  market is famous for its racing stables, and the Suffolk coast is dotted  with holiday resorts. The county seat is Ipswich.</p><p>Suffolk Breed of medium-wool, dark-faced, hornless sheep developed in  England in the early 19th century by mating Norfolk horned ewes  (females) with Southdown rams (males). Suffolks are prolific, early-  maturing sheep with excellent mutton carcasses. They are energetic and  have an alert carriage and great stamina. Introduced into the U.S. in 1888,  the Suffolk is a popular lamb producer.</p><p>Suffolk, Thomas Howard, 1 st earl of (b. Aug. 24, 1561�d. May  28, 1626, London, Eng.) English naval officer and politician. Son of the  4th duke of Norfolk, Howard held naval commands and distinguished  himself in the attack on the Spanish Armada (1588). He led naval forays</p><p>against the Spanish in the reign of Elizabeth I. Created earl of Suffolk in  1603, he served James I as lord chamberlain (1603-14) and lord high trea�  surer (1614-18). In 1618 he was deprived of his office on charges of  embezzlement and was briefly imprisoned with his wife, who had taken  bribes from Spain.</p><p>Sufism Vsti-.fi-zonA Mystical movement within Islam that seeks to find  divine love and knowledge through direct personal experience of God. It  consists of a variety of mystical paths that are designed to ascertain the  nature of mankind and God and to facilitate the experience of divine love  and wisdom in the world. Sufism arose as an organized movement after  the death of Muhammad (ad 632), among different groups who found  orthodox Islam to be spiritually stifling. The practices of contemporary  Sufi orders and suborders vary, but most include the recitation of the name  of God or of certain phrases from the Qu�ran as a way to loosen the bonds  of the lower self, enabling the soul to experience the higher reality toward  which it naturally aspires. Though Sufi practitioners have often been at  odds with the mainstream of Islamic theology and law, the importance of  Sufism in the history of Islam is incalculable. Sufi literature, especially  love poetry, represents a golden age in Arabic, Persian, Turkish, and Urdu  languages.

Sugars (whose names end in - ose ) are the simplest carbohy�  drates. The most common is sucrose, a disaccharide; there are numerous  others, including glucose and fructose (both monosaccharides); invert  sugar (a 50:50 mixture of glucose and fructose produced by enzyme action  on sucrose); and maltose (produced in the malting of barley) and lactose  (both disaccharides). Commercial production of sugars is almost entirely  for food.</p><p>Sugar Act (1764) British legislation to raise revenue from North Ameri�  can colonies. A revision of the unenforced Molasses Act of 1733, it  imposed new duties on sugar and molasses imported into the colonies  from non-British Caribbean sources and provided for the seizure of car�  goes violating the new rules. The act was the first attempt to recoup from  the colonies the expenses of the French and Indian War and the cost of  maintaining British troops in North America. The colonists objected to  the act as taxation without representation, and some merchants agreed not  to import British goods. Protests increased with passage of the Stamp Act.</p><p>sugar beet Variety of beet (Beta  vulgaris ) that accounts for about  two-fifths of global sugar produc�  tion, making it second only to sug�  arcane as a source of the world�s  sugar. Unlike sugarcane, sugar beets  can be grown in temperate or cold  climates in Europe, North America,  and Asia; that is, within the densely  populated, well-developed areas  where much of the product is con�  sumed. The sugar beet was grown as  a garden vegetable and for fodder  long before it was valued for its  sugar content.</p><p>sugarcane Giant, thick, perennial  GRASS ( Saccharum officinarum\ fam�  ily Poaceae, or Gramineae), culti�  vated in tropical and subtropical  regions worldwide for its sweet sap, a  major source of sugar and molasses.</p><p>The plant grows in clumps of solid  stalks with regularly spaced nodes or  joints, each with a bud that can be  planted for commercial asexual  propagation.

March 26, 903, Dazaifu) Japanese scholar of Chinese literature  during the Heian period, later deified as Tenjin, patron of scholarship and  literature. He was given important government posts by the emperor Uda,  who saw him as a counterbalance to the powerful Fujiwara family. When  Uda�s son took the throne, Michizane�s fortunes were reversed, and he  was sent into exile when the new emperor was persuaded that Michizane  was plotting against him. Following his death in exile, calamities in the  capital were attributed to his vengeful spirit, and he was posthumously  reinstated. At shrines dedicated to Tenjin, schoolchildren often buy amu�  lets for good luck on school entrance exams.</p><p>Suger \suj-'zher\ (b. 1081, near Paris�d. Jan. 13, 1151) Abbot of Saint-  Denis and adviser to Louis VI and Louis VII. A peasant boy educated at the  abbey of Saint-Denis, he was a schoolmate and close friend of the future  Louis VI. In 1122 he was elected abbot, and he used popular veneration  for the saint and for the church�s banner to rally military support for the  king. Suger�s work on the church of Saint-Denis was instrumental in the  development of Gothic architecture. He arranged a treaty ending the civil  war between Louis VII and his vassal Thibaut, and he served as regent  (1147-49) while the king was away on the Second Crusade.</p><p>Suharto (b. June 8, 1921, Kemusu Argamulja, Java, Dutch East Indies)  Second president of Indonesia  (1967-98). Suharto initially served  in the Dutch colonial army, but after  the Japanese conquest (1942) he  joined a Japanese-sponsored defense  corps. After Japan�s surrender he  joined the guerrilla forces seeking  independence from the Dutch. When  Indonesia became independent  (1950), he was a lieutenant colonel.</p><p>A strong anticommunist, he crushed  what was purported to be an  attempted communist coup d�etat in  1965 with a ruthless purge of com�  munists and leftists throughout the  country that left as many as 1,000,000 dead. He deposed the sitting presi�  dent, Sukarno, and was himself appointed president in 1967. He estab�  lished authoritarian rule and was repeatedly elected without opposition.  In 1975 he brutally annexed the former Portuguese colony of East Timor.  A severe economic downturn focused public attention on his govern�  ment�s corruption, and this led to massive demonstrations that prompted  his resignation in 1998, after 31 years in power.</p><p>Suhrawardi V.suh-ra-'war-deX, al- in full Shihab al-DIn Yahya  ibn Habash ibn Amlrak al-Suhraward? or al-MaqtuI (b. c.</p><p>1155, Suhraward, Iran�d. 1191, Aleppo, Syria) Muslim theologian and  philosopher. He studied in Esfahan, a leading centre of Islamic scholar�  ship. His works fell into two categories: doctrinal and philosophical tracts,  many of which took account of the ancient Greek philosophers, and  shorter treatises intended to guide the mystic toward esoteric knowledge.  His best-known work. The Wisdom of Illumination, held that existence is  a single continuum that culminates in pure light, representing God.  Charged with heresy by rivals in the Muslim clergy, he was executed by  the Ayyubid prince Malik al-Zahir�thus earning himself the appellation  al-Maqtul (�the Killed�).</p><p>Sui \'swe\ dynasty (581-618) Short-lived Chinese dynasty that unified  northern and southern China after centuries of division. Under the Sui,  the cultural and artistic renaissance that was to reach its height under the  succeeding Tang dynasty was set in motion. The first Sui emperor, Wendi,  established uniform institutions of government throughout the country,  promulgated a new legal system, conducted a census, recruited officials  through examinations, and reestablished Confucian rituals. The Sui con�  ducted three costly and unsuccessful campaigns against the Korean king�  dom of Koguryo. The Sui capital at Chang 7 an was, in design, six times  the size of the modern city of Xi�an at the same site.</p><p>suicide Act of intentionally taking one�s own life. Suicide may have psy�  chological origins such as the difficulty of coping with depression or other  mental disorders; it may be motivated by the desire to test the affection of  loved ones or to punish their lack of support with the burden of guilt. It may</p><p>also stem from social and cultural pressures, especially those that tend to  increase isolation, such as bereavement or estrangement. Attitudes toward  suicide have varied in different ages and cultures; convicted criminals in  ancient Greece were permitted to take their own lives, and the Japanese  custom of seppuku (also called hara-kiri), or self-disembowelment, allowed  samurai to commit ritual suicide as a way of protecting honour and dem�  onstrating loyalty. Jews committed suicide rather than submit to ancient  Roman conquerors or crusading knights who intended to force their con�  version. In the 20th century, members of new religious movements, notably  the Peoples Temple and Heaven�s Gate, committed mass suicide. Buddhist  monks and nuns have also committed sacrificial suicide by self-immolation  as a form of social protest. Japan�s use of kamikaze suicide bombers during  World War II was a precursor to the suicide bombing that emerged in the  late 20th century as a form of terrorism, particularly among Islamic extrem�  ists. Suicide, however, is generally condemned by Islam, Judaism, and  Christianity, and attempts to commit suicide are still punishable by law in  many countries. Some communities around the world have sought to legal�  ize physician-assisted suicide for the terminally ill. Euthanasia was legal�  ized in The Netherlands in 2001 and Belgium in 2002, and it is openly  practiced in Colombia. Since the 1950s suicide-prevention organizations  have been established in many countries, with telephone hot lines serving  as a source of readily available counseling.</p><p>Suir \'shur. River River, southeastern Ireland. It rises in northern  County Tipperary and flows south and east. It is joined by the Barrow and  the Nore before entering Waterford Harbour 114 mi (183 km) later. In the  1760s the river was made navigable to Clonmel.</p><p>suite Set of instrumental dances or dancelike movements. The suite  originated in the paired dances of the 14th-16th centuries (pavane-  galliard, basse danse-saltarello, etc.). In the 16th� 17th centuries German  composers began to write sets of three or four dances, as in Johann Her�  mann Schein�s Banchetto musicale (1617). In the late 17th century a basic  ordering of four dances� allemande, courante, sarabande, and gigue�  became established as standard; other dances came to be interpolated  between the sarabande and gigue. In the 19th century suite came to refer  to sets of instrumental excerpts from operas and ballets.</p><p>Sukarno (b. June 6,1901, Surabaja, Java, Dutch East Indies�d. June 21,  1970, Jakarta, Indon.) First president of Indonesia (1949-67). Son of a Jav�  anese schoolteacher, he excelled in languages, mastering Javanese, Sun-  danese, Balinese, and modern Indonesian, which he did much to create. He  emerged as a charismatic leader in the country�s independence movement.  When the Japanese invaded in 1942, he served them as a chief adviser,  while pressuring them to grant Indonesia independence. Immediately fol�  lowing Japan�s defeat, he declared independence; the Dutch did not trans�  fer sovereignty until 1949. Once he became president, Indonesia made  gains in health, education, and cultural self-awareness, but democracy and  the economy foundered. His government was corrupt, inflation soared, and  the country experienced a continuous state of crisis. An attempted coup,  purportedly by communists, in 1965 led to a military takeover by Suharto  and a purge of alleged communists. Stripped of his power in 1966, Sukarno  resigned in 1967 and lived under house arrest until his death.</p><p>Sukhothai \'su-k3-'tl\ kingdom Former kingdom, north-central Thai�  land. It was founded in the mid-13th century when a local Tai ruler led a  revolt against Khmer rule. It remained only a small local power until its  third ruler, Ramkhamhaeng, inherited the kingdom c. 1279. He extended  its power to the south onto the Malay Peninsula, to the west into what is  now Myanmar (Burma), and to the northeast into modem Laos. On his  death in 1298 the kingdom began to lose its power, and in 1438 it was  absorbed into the kingdom of Ayutthaya.</p><p>Sukhothai style Vsii-ko-'tA Canonical style for Buddha icons devel�  oped probably in the kingdom of Sukhothai (modern Thailand), begin�  ning in the 14th century.

In the 1950s and �60s OKB-51 planned and built a series  of supersonic jet fighters, including the Su-7 and Su-9, which were later  modified and used extensively by the U.S.S.R. and other Warsaw Pact  countries. It improved the Su-9 into the Su-11 and Su-15 fighter-  interceptors. After Sukhoy�s death (1975) his name was added to that of the  bureau. Perhaps the best known Sukhoy design was the versatile Su-27 air-  superiority fighter (first flown 1977). In the 1990s the bureau introduced the  Su-34 fighter-bomber and the redesigned Su-39 ground-attack aircraft. Its  fifth-generation multirole S-37 Berkut air-superiority fighter (1997), had  state-of-the-art electronics, forward-swept wings, and thrust vector con�  trol. In 1997 Russia formed the partially state-owned AVPK Sukhoy by  combining the design bureau with its production plant and other affiliates.  At the start of the 21st century Sukhoy began diversifying into the civilian  market with sports aircraft, freight vehicles, and passenger aircraft.</p><p>sukiya \su-'ke-3\ style Japanese architectural style developed in the  Azuchi-Momoyama (1574-1600) and Tokugawa (1603-1867) periods,  originally used for teahouses and later also for private residences and res�  taurants. Based on an aesthetic of naturalness and rustic simplicity, build�  ings in this style are intended to harmonize with their surroundings.  Timber construction is employed, with wood left in a natural state, some�  times with the bark still attached. Walls are typically made of clay. Great  attention is paid to detail and proportions, and the effect is one of refined  simplicity. The architect Yoshida Isoya (1894-1974) pioneered a modern  sukiya style using contemporary materials.</p><p>Sulaiman Range Vsii-lI-.manX Mountain range, central Pakistan, west  of the Indus River.

He became sultan of the Ottoman Empire after  serving as a provincial governor under his grandfather Bayezid II and his  father, Selim I (r. 1512-20). He immediately began leading campaigns  against the Christians, taking Belgrade (1521) and Rhodes (1522). At the  Battle of Mohacs (1526) he broke the military strength of Hungary. In  1529 he laid siege to Vienna but failed to capture it. Further campaigns  in Hungary (1541, 1543) left the region divided between Habsburg- and  Ottoman-dominated areas. Iraq and eastern Anatolia were captured dur�  ing his first campaign (1534-35) against the Persian Safavid dynasty; his  second (1548-49) brought conquests in southern Anatolia around Lake  Van; but his third (1554-55) was unsuccessful. His navy, under Bar-  barossa, controlled the Mediterranean Sea. He built mosques, bridges, and  aqueducts and surrounded himself with great poets and legal scholars. His  reign is considered a high point of Ottoman civilization.</p><p>sulfa drug Common term for sulfonamide drug, any member of a class  of synthetic antibacterial drugs with a particular chemical structure includ�  ing both sulfur and nitrogen atoms. Their effectiveness against bacteria  was discovered in 1932 by Gerhard Domagk, and they became the first  chemical substances systematically used against human bacterial infec�  tions. Sulfa drugs inhibit the growth and multiplication of certain bacteria  (but do not kill them) by interfering with the synthesis of fouc acid.  Because of their toxicity and growing bacterial resistance, sulfa drugs are  no longer in common use (except for urinary-tract infections, certain  forms of malaria, and preventing infection of burns), having been largely  superseded by less toxic antibiotics.</p><p>sulfate Any of numerous inorganic and organic chemical compounds  related to sulfuric acid (H 2 S0 4 ). One subgroup comprises salts containing  the sulfate ion (S0 4 2- ) linked via ionic bonds with any of various cations.  Another subgroup of sulfates, the esters, are organic compounds in which  sulfuric acid�s hydrogen atoms are replaced by organic groups (e.g.,  methyl, ethyl, phenyl); a carbon atom in the organic group bonds to an  oxygen atom, whose second bond is to the sulfur atom. (In sulfonates, a  carbon atom bonds directly to the sulfur atom.) See also bonding.</p><p>sulfide mineral or sulphide mineral Any member of a group of  compounds of sulfur with one or more metals. The metals that occur most  commonly are iron, copper, nickel, lead, cobalt, silver, and zinc. They are</p><p>the ore minerals of most metals used  by industry (e.g., antimony, bismuth,  copper, lead, nickel, and zinc). Other  industrially important metals such as  cadmium and selenium occur in  trace amounts in numerous common  sulfides and are recovered in refining  processes.</p><p>sulfur Nonmetallic chemical ele�  ment, chemical symbol S, atomic  number 16. It is very reactive but  occurs native in deposits, as well as  combined in various ores (e.g., pyrite,</p><p>GALENA, CINNABAR); in COAL, PETROLEUM,  and natural gas; and in the water in  sulfur springs. Sulfur is the third  most abundant constituent of miner�  als and one of the four most impor�  tant basic chemical commodities.</p><p>Pure sulfur, a tasteless, odourless,  brittle yellow solid, occurs in several  crystalline and amorphous allo-  tropes, including brimstone and  flowers of sulfur. It combines, with  valence 2, 4, or 6, with nearly all  other elements. Its most familiar  compound is hydrogen sulfide, a poi�  sonous gas that smells like rotten  eggs. All metals except gold and  platinum form sulfides, and many  ores are sulfides. The oxides are sulfur dioxide and sulfur trioxide, which  when dissolved in water make sulfurous acid and sulfuric acid, respec�  tively. Several sulfur compounds with halogen elements are industrially  important. Sodium sulfite (Na 2 S0 3 ) is a reducing agent used to pulp paper  and in photography. Organic compounds with sulfur include several amino  acids, the sulfa drugs, and many insecticides, solvents, and substances used  in making rubber and rayon.</p><p>sulfur bacteria Any of a diverse group of bacteria that are capable of  metabolizing sulfur and its compounds and are important in the sulfur  cycle. Members of the genus Thiobacillus, widespread in marine and ter�  restrial habitats, react with sulfur to produce sulfates useful to plants; in  deep ground deposits they generate sulfuric acid, which dissolves metals  in mines and corrodes concrete and steel. Desulfovibrio desulficans  reduces sulfates in waterlogged soils and sewage to hydrogen sulfide, a  gas with the common rotten-egg odour.</p><p>sulfur butterfly See sulphur butterfly</p><p>sulfur dioxide Inorganic compound, heavy, colourless, poisonous gas  (S0 2 ). It has a pungent, irritating odour (the smell of a just-struck match).  It occurs in volcanic gases and dissolved in the waters of some warm  springs. Huge quantities are made industrially for use as a bleach, as a  reducing agent, and as sulfites, which are food preservatives. It is a pre�  cursor of the trioxide (S0 3 ), used to make sulfuric acid. Sulfur dioxide is  formed when sulfur-containing fuels are burned; in the atmosphere it can  combine with water vapour to form sulfuric acid, a major component of  ACID RAIN.</p><p>sulfuric \,s3l-'fyur-ik\ acid or oil of vitriol Dense, colourless, oily,  corrosive liquid inorganic compound (H 2 S0 4 ). A very strong acid, it forms  ions of hydrogen or hydronium (H + or H 3 0 + ), hydrogen sulfate (HS0 4 ),  and sulfate (SOj - ). It is also an oxidizing (see oxidation-reduction) and  dehydrating agent and chars many organic materials. It is one of the most  important industrial chemicals, used in various concentrations in manu�  facturing fertilizers, pigments, dyes, drugs, explosives, detergents, and  inorganic salts and acids, in petroleum refining and metallurgical pro�  cesses, and as the acid in lead-acid storage batteries. It is made industri�  ally by dissolving sulfur trioxide (S0 3 ) in water, sometimes beyond the  saturation point to make oleum (fuming sulfuric acid), used to make cer�  tain organic chemicals.</p><p>Sulla (Felix), Lucius Cornelius (b. c. 138�d. 79 bc, Puteoli, near  Naples) Victor in the Roman civil war (88-82) and dictator (82-79).

May 13, 1842, London,</p><p>Eng.�d. Nov. 22, 1900, London)</p><p>British composer. He attended the  Royal Academy and the Leipzig  Conservatory, then supported himself by teaching, playing organ, and  composing for provincial festivals. His music for The Tempest (1861)  achieved great success and was followed by his Irish Symphony (1866)  and songs such as �Onward, Christian Soldiers� and �The Lost Chord.�  In 1871 he first collaborated in comic opera with playwright W.S. Gilbert,  and in 1875 their Trial by Jury became a hit, setting the course for both  their careers. Their collaboration continued with The Sorceror (1877),  H.M.S. Pinafore (1878), The Pirates of Penzance (1879), Patience (1881),  Iolanthe (1882), Princess Ida (1883), The Mikado (1885), Ruddigore  (1887), The Yeomen of the Guard (1888), The Gondoliers (1889), and  others, many of which would continue to delight international audiences  for more than a century.</p><p>Sullivan, Ed(ward Vincent) (b. Sept. 28, 1901, New York, N.Y.,  U.S.�d. Oct. 13, 1974, New York City) U.S. television host. He began  his career as a journalist and wrote a Broadway gossip column for the  Daily News. Known for his talent at discovering interesting new perform�  ers, he was hired by CBS to host its variety program Toast of the Town  (1948-55), later called The Ed Sullivan Show (1955-71), where he pre�  sented diverse entertainment (combining, for example, a concert pianist,  a singing fireman, and a boxing referee with Hollywood celebrities in a  single show) in a program that became a national institution for more than  20 years. Sullivan�s terse way of introducing guest performers and dis�  tinctive mannerisms made him a popular target for comedians.</p><p>Sullivan, Harry Stack (b. Feb. 21, 1892, Norwich, N.Y., U.S.�d.  Jan. 14, 1949, Paris, France) U.S. psychiatrist. He engaged in clinical  research at the Pratt Hospital in  Maryland (1923-30), pursuing his  interest in the use of psychotherapy  to treat schizophrenia, which he  viewed as stemming from disturbed  interpersonal relationships in early  childhood. He asserted that psychi�  atric symptoms arise out of conflicts  between the individual and his  human environment and that person�  ality development likewise stems  from a series of interactions with  other people. He helped establish the  William Alanson White Psychiatric  Foundation (1933) and the Washing�  ton School of Psychiatry (1936), and  he also founded (1938) and served as  editor of the journal Psychiatry. His  works include The Interpersonal  Theory of Psychiatry (1953) and The  Fusion of Psychiatry and Social Sci�  ence (1964).</p><p>Sullivan, John L(awrence) (b.</p><p>Oct. 15, 1858, Roxbury, Mass.,</p><p>U.S.�d. Feb. 2, 1918, Abington, Mass.) U.S. boxer. Sullivan became the  world heavyweight champion in 1882 by knocking out Paddy Ryan in  nine rounds. His 75-round knockout of Jake Kilrain in 1889 was the last  title bout under London Prize Ring (bare-knuckle) rules. In his only cham�  pionship defense under the Queensberry rules, he was knocked out by Jim  Corbett (b. 1866�d. 1933) in 21 rounds in 1892. From 1878 to 1905  Sullivan had 35 bouts, of which he won 31, 16 by knockouts. Some box�  ing historians regard Sullivan only as a U.S. champion since he had only  one international match of consequence and refused to fight the great  black Australian heavyweight Peter Jackson.</p><p>Sullivan, Louis H(enry) (b. Sept. 3, 1856, Boston, Mass., U.S.�d.  April 14, 1924, Chicago, Ill.) U.S. architect, the father of modern U.S.  architecture. Sullivan was accepted at the Ecole des Beaux-Arts in Paris  but was a restless student. After working for several Chicago firms, he  joined the office of Dankmar Adler (1844-1900) in 1879, becoming  Adler�s partner at age 24. Their 14-year association produced more than  100 buildings, many of them landmarks. Their first important work was  the Auditorium Building in Chicago (1889), a load-bearing stone struc�  ture with a 17-story tower, unadorned on the arcaded exterior and daz-  zlingly rich on the interior. Their most important skyscraper is the 10-story  steel-framed Wainwright Building, St. Louis, Mo. (1890-91); above its  two-story base, the vertical elements are stressed and horizontals recessed,  and it is capped by a decorative frieze and cornice. During this period the  young Frank Lloyd Wright spent six years as apprentice to Sullivan, who  would be a major influence on the younger architect. In 1895 Sullivan�s  partnership with Adler dissolved, and his practice began a steady decline.  One of his few major commissions was the Carson Pirie Scott store in  Chicago (1899-1904), noted for its broad windows and exuberant orna�  mentation. Sullivan�s ornamentation was based not on precedent but on  geometry and natural forms. He considered it obvious that building design  should indicate a building�s functions and that, where the function does  not change, the form should not change; hence his influential dictum  �form follows function.�</p><p>Sully \sie-'le\, Maximilien de Bethune, duke de (b. Dec. 13,  1560, Mantes, France�d. Dec. 22, 1641, Villebon) French statesman. Son  of a French Huguenot noble, he was sent to the court of Henry of Navarra  (later Henry IV). He fought in the Wars of Religion and helped negotiate  the Peace of Savoy (1601). As superintendent of finances from 1598, he  instituted reforms in taxation and administration. A trusted agent to the  king, he was rewarded with royal offices and created duke de Sully in  1606. He promoted a system of national improvements, encouraged agri�  culture, and strengthened the military. His political role ended with Hen�  ry�s assassination (1610), and he resigned in 1611.</p><p>Sully Prudhomme VsiE-le-prLe-'doirA orig.

Inspired at first by an unhappy  love affair, he published fluent and  melancholic verse in volumes begin�  ning with Stances et poemes (1865),  containing his well-known �Le Vase  brise.� He later adopted the more  objective approach of the Parnassian  poets and attempted to represent  philosophical concepts in verse.</p><p>Among his best-known later works  are La Justice (1878) and Le Bon-  heur( 1888). In 1901 he was awarded  the first Nobel Prize for Literature,  over such greatly admired figures as  Leo Tolstoy.</p><p>sulphide mineral See sulfide min�  eral</p><p>sulphur butterfly or sulfur butterfly Any of several species of  butterflies (family Pieridae) that are found worldwide.

A double island chain, it extends  170 mi (270 km) and includes about 400 named islands and more than  500 unnamed ones; they cover an area of 1,038 sq mi (2,688 sq km). The  islanders were converted to Islam by Abu Bakr in the mid-15th century.  The Spanish tried, at first unsuccessfully, to subdue the inhabitants, whom  they called Moros. The islands finally became a Spanish protectorate in  the 19th century, and in 1899 came under U.S. authority. The archipelago  was ceded to the Philippines in 1940. The islands provide a haven for  smugglers and pirates.</p><p>Sulzberger Ysslz-.bar-garV, Arthur Hays (b. Sept. 12, 1891, New  York, N.Y., U.S.�d. Dec. 11, 1968, New York City) U.S. newspaper-  publisher. The son-in-law of Adolph Ochs, he joined the staff of The New  York Times after marrying Iphigene Ochs in 1917. He was the paper�s pub�  lisher (1935-61), overseeing the extension of its news coverage into more  specialized subject areas as well as important changes in technology and  a growth in circulation. He was succeeded by his son, Arthur Ochs  Sulzberger.</p><p>Sulzberger, Arthur Ochs (b. Feb. 5, 1926, New York, N.Y., U.S.)  U.S. newspaper publisher. Grandson of Adolph Ochs and son of Iphigene  and Arthur Hays Sulzberger, he spent a dozen years as a reporter and in  other newspaper posts before becoming publisher of The New York Times  in 1963. During his tenure he introduced many innovations that strength�  ened the paper�s reputation while modernizing and streamlining the orga�  nization of its staff, including the unification of the daily Times with the  Sunday edition in 1964 and an increase in coverage of fields such as eco�  nomics, the environment, medicine, law, and science. In 1992 he was suc�  ceeded by his son, Arthur Sulzberger, Jr. (b. 1951).</p><p>sumac Vshu-.mak, 'su-,mak\ Any of certain species of shrubs and small  trees in the genus Rhus of the family Anacardiaceae (the sumac, or cashew,  family), native to temperate and subtropical zones. All sumacs have a  milky or resinous sap, which in some species (e.g., poison sumac) can irri�  tate the skin. Used in the past as a source of dyes, medicines, and beverages,  sumacs are now valued as ornamentals, soil binders, and cover plants. The  sumacs grown for landscape use display a graceful form, spectacular fall  colour, or colourful fruit clusters. The smooth, or scarlet, sumac ( R . gla�  bra ), native to the eastern and central U.S., is the most common.</p><p>Sumatra \su-'ma-tro\ Island (pop., 2000 including adjoining islands:  43,309,707), western Indonesia. It is one of the Sunda Islands and the sec�  ond largest island of Indonesia. It is 1,060 mi (1,706 km) long and 250  mi (400 km) wide. A chief city is Palembang. Located on the seaborne  trade routes, the island had early contact with Hindu civilization. The  Srivijaya empire arose in the 7th century and came to dominate much of the  island. It fell under the Majapahit empire in the 14th-16th centuries. First  the Portuguese, then the Dutch and English established forts there begin�  ning in the 16th century. It was occupied by Japan in World War II and  in 1950 became part of the Republic of Indonesia. Its exports include rub�  ber, tobacco, coffee, pepper, and timber products; mineral reserves include  petroleum and coal. In 2004 a large tsunami generated by a massive  earthquake off the west coast of Sumatra caused widespread death and  destruction in coastal areas bordering the Indian Ocean.</p><p>Sumba \'sum-ba\ English Sandalwood Island Island, Lesser  Sunda Islands, Indonesia. The island, 140 mi (225 km) long and up to 50  mi (80 km) wide, is mainly a high plateau with good harbours on the  northern coast. Its chieftains were brought by treaty under Dutch control  in 1756. Sumba became part of independent Indonesia in 1950. It is  known for the Sandalwood horse and Ongole cattle, and its woven cloth  is famous for its design. Corn is the main crop; copra is exported.</p><p>Sumbawa \sum-'ba-wa\ Island, Lesser Sunda Islands, Indonesia. Its  irregular coastline includes Bima Bay, one of the best harbours in Indo�  nesia. The island, 175 mi (282 km) long and 55 mi (88 km) wide, is  mountainous. Its highest point is volcanic Mount Tambora (9,354 ft [2,851  m]), which erupted in 1815, killing 50,000 people. Sumbawa was once  part of the Majapahit empire. In 1674 the Sumbawanese nobility signed  agreements that gave the Dutch East India Company some power over the  island; the Dutch gained direct control in the early 20th century. Sum�  bawa became part of independent Indonesia in 1950. Agricultural prod�  ucts include rice, com, coffee, and copra.</p><p>Sumer Vsii-morX Region of southern Mesopotamia and site of the earli�  est known civilization. It was first settled c. 4500-4000 bc by a non-  Semitic people called the Ubaidians. They were the first civilizing force  in Sumer, draining the marshes for agriculture and developing trade. The  Sumerians, who spoke a Semitic language that came to dominate the  region, arrived c. 3300 bc and established the world�s first known cities.  These polities evolved into city-states, which eventually developed  monarchical systems that later came to be loosely united under a single  city, beginning with Kish c. 2800 bc. Thereafter, Kish, Erech, Ur, Nippur,  and Lagash vied for ascendancy for centuries. The area came under the  control of dynasties from outside the region, beginning with Elam (c.  2530-2450 bc) and later Akkad, led by the Akkadian king Sargon (r.  2334-2279 bc). After the Akkadian dynasty collapsed, the city-states were  largely independent until they were reunified under the 3rd dynasty of Ur  (21st-20th centuries bc). That final Sumerian dynasty declined after being  weakened by foreign invasions, and the Sumerians as a distinct political  entity disappeared, becoming part of the Babylonia in the 18th century bc.  The Sumerian legacy includes a number of technological and cultural  innovations, including the first known wheeled vehicles, the potter�s  wheel, a system of writing (see cuneiform), and written codes of law.</p><p>Summerhill School Experimental primary and secondary boarding  school in Leiston, Suffolk, England. Founded in 1921 by Alexander Suth�  erland Neill (1883-1973), the school is self-governing (students and staff  have a voice in policy matters) and emphasizes the student�s own moti�  vation to learn (class attendance is optional). Neill�s highly influential and  controversial book Summerhill (1960) stimulated much debate about alter�  natives to conventional schooling, particularly in the U.S.</p><p>summons In law, written notification that one is required to appear in  court. In civil (noncriminal) cases, it notifies a defendant that he or she  must appear and defend (e.g., by filing an answer) within a specified time  or a default judgment will be rendered for the plaintiff. The summons is  also used in cases involving minor criminal offenses (e.g., traffic viola�  tions) to call defendants to appear and answer to charges against them.

He practiced law while cru�  sading for the abolition of slavery,  prison reform, world peace, and edu�  cational reform. He was elected to  the U.S. Senate (1852-74) and spoke  out against slavery. He denounced  the Kansas-Nebraska Act as the  �crime against Kansas� and scorned  its authors, Sen. Stephen A. Douglas  and Sen. Andrew R Butler. In 1856  an incensed relative of Butler, Con�  gressman Preston S. Brooks of South  Carolina, invaded the Senate and  severely beat Sumner with a cane.</p><p>He returned to the Senate in 1859,  and as chairman of the foreign rela�  tions committee (1861-71) he  helped resolve the Trent Affair.</p><p>Sumner, James (Batcheller)</p><p>(b.

In 1926 he became the first researcher to  crystallize an enzyme (urease); he later crystallized catalase and worked on  purification of various other enzymes, which led to recognition that most  enzymes are proteins. This work earned him (with John Howard Northrop  and Wendell Meredith Stanley) a 1946 Nobel Prize.

June 1,  1832, South Mount, S.C., U.S.) American Revolutionary officer. He  served in the French and Indian War and later moved to South Carolina.  In the American Revolution he was commissioned a brigadier general and  escaped to North Carolina after the fall of Charleston (1780). He led the  state militia to victories over the British in several engagements. He  served in the U.S. House of Representatives (1789-93, 1797-1801) and  the Senate (1801-10). Fort Sumter was named for him (see Fort Sumter  National Monument).</p><p>Sun Star around which the components of the solar system revolve. It is  about five billion years old and is the dominant body of the system, with  more than 99% of its mass. It converts five million tons of matter into  energy every second by nuclear fusion reactions in its core, producing neu�  trinos (see solar neutrino problem) and solar radiation. The small amount of  this energy that penetrates Earth�s atmosphere provides the light and heat  that support life. A sphere of luminous gas 864,950 mi (1,392,000 km) in  diameter, the Sun has about 330,000 times the mass of Earth. Its core tem�  perature is close to 27 million �F (15 million �C) and its surface tempera�  ture about 10,000 �F (6,000 �C). The Sun, a spectral type G (yellow) star,  has fairly average properties for a main-sequence star (see Hertzsprung-  Russell diagram). It rotates at different rates at different latitudes; one rota�  tion takes 36 days at the poles but only 25 days at the equator. The visible  surface, or photosphere, is in constant motion, with the number and position  of sunspots changing in a regular solar cycle. External phenomena include  magnetic activity extending into the chromosphere and corona, solar flares,  solar prominences, and the solar wind. Effects on Earth include auroras and  disruption of radio communications and power-transmission lines. Despite  its activity, the Sun appears to have remained relatively unchanged for bil�  lions of years. See also eclipse; heliopause.</p><p>sun bear or honey bear Smallest member (Helarctos malayanus ) of  the bear family (Ursidae), found in South Asian forests. Nocturnal and  tree-climbing, the sun bear weighs 60-140 lbs (27-64 kg) and is 3-4 ft  (1-1.2 m) long, with a 2-in. (5-cm) tail, large forepaws, and short black  fur with an orange-yellow crescent on the chest. It uses its long, curved  claws to tear or dig for insect nests, particularly those of bees and ter�  mites. It also eats fruit, honey, and small vertebrates. The sun bear is shy  and intelligent; legends say that its chest crescent represents the sun.</p><p>sun dance Most spectacular and important religious ceremony of the  19th-century Plains Indians. Ordinarily held by each tribe once a year in  early summer, it was an occasion for purification and strengthening and  an opportunity to reaffirm basic beliefs about the universe and the super�  natural through rituals. The ceremony, which originated with the Lakota,  was most highly developed among the Arapaho, the Cheyenne, and the  Oglala division of the Lakota Sioux. The central rite involved male danc�  ers who, to fulfill a vow or seek �power� (spiritual energy and insight),  danced for several days without stopping for food, drink, or sleep, their  ordeal ending in frenzy and exhaustion. Among some tribes, piercing and  sun gazing were practiced.</p><p>sun worship Veneration of the sun or its representation as a deity. It  appears in several early cultures, notably in ancient Egypt, Indo-Europe,  and Mesoamerica, where urban civilizations were combined with a strong  ideology of sacred kingship, in which kings ruled by the power of the sun  and claimed descent from it. The imagery of the sun as the ruler of both  the upper and the lower world, which he visits daily, was prominent. Sun  heroes and deities also figure in many mythologies, including Indo-  Iranian, Greco-Roman, and Scandinavian. In late Roman history, sun wor�  ship was of such importance that it was later called �solar monotheism.�  See also Amaterasu, Re, Shamash, Sol, Surya, Tonatiuh.</p><p>Sun Yat-sen Vsun-'yat-'senV or Sun Yixian Vsim-'e-she-'onV (b.

Educated in Hawaii and Hong Kong, Sun embarked on a  medical career in 1892, but, troubled by the conservative Qing dynasty�s  inability to keep China from suffering repeated humiliations at the hands  of more advanced countries, he forsook medicine two years later for poli�  tics. A letter to Li Hongzhang in which Sun detailed ways that China could  gain strength made no headway, and he went abroad to try organizing</p><p>expatriate Chinese. He spent time in  Hawaii, England, Canada, and Japan  and in 1905 became head of a revo�  lutionary coalition, the Tongmenghui  (�Alliance Society�). The revolts he  helped plot during this period failed,  but in 1911 a rebellion in Wuhan  unexpectedly succeeded in over�  throwing the provincial government.</p><p>Other provincial secessions fol�  lowed, and Sun returned to be  elected provisional president of a  new government. The emperor abdi�  cated in 1912, and Sun turned over  the government to Yuan Shikai. The  two men split in 1913, and Sun  became head of a separatist regime  in the south. In 1924, aided by Soviet  advisers, he reorganized his Nation�  alist Party, admitted three commu�  nists to its central executive committee, and approved the establishment  of a military academy, to be headed by Chiang Kai-shek. He also delivered  lectures on his doctrine, the Three Principles of the People (nationalism,  democracy, and people�s livelihood), but died the following year without  having had the opportunity to put his doctrine into practice.

More common and severe in  light-skinned people, it ranges from mild redness and tenderness to intense  pain, edema, and blistering, sometimes with shock, fever, and nausea. The  process begins after 15 minutes in the sun, but redness starts 6-12 hours  later and peaks within a day. Pigment cells in the skin increase melanin  production (�tan�). Cold compresses and analgesics reduce pain. Limit�  ing sun exposure, using sunscreen, and wearing protective clothing can  prevent severe sunburn. Long-term sun exposure can eventually cause skin  cancer, as well as skin wrinkling and thickening.</p><p>Sunda Islands Archipelago extending from the Malay Peninsula to the  Moluccas.

First mentioned in the 8th century ad, they are  one of the three principal ethnic groups on the island. They once followed  Mahay ana Buddhism but converted to Islam in the 16th century under the  influence of Muslim trade. Sundanese villages are ruled by a headman  and a council of elders. Marriage, birth, and death ceremonies conform  closely to the Javanese pattern but are often mixed with Hindu elements.

Located at the mouth of the River Wear on  the North Sea, the town was known as Wearmouth in Saxon times; it for�  merly included Monkwearmouth, site of a monastery built in 674 where  the Venerable Bede studied. Sunderland itself (named for the part of  Monkwearmouth �sundered� from the monastery by the river) was char�  tered in the late 12th century. The port grew rapidly as the coal trade  developed in the 17th century, and by the mid- 18th century it was a major  shipbuilding centre. Modern industries include glassware and automobile  manufacturing. Within the borough are the seaside resorts of Roker and  Seabum. In addition to the town of Sunderland, the city and metropoli�  tan borough includes the towns of Washington, Houghton-le-Spring, and  Hetton-le-Hole.</p><p>Sunderland, Robert Spencer, 2nd earl of (b.

After a period in diplomatic service, he twice served as  secretary of state (1679-81, 1683) and became the chief architect of  Charles�s pro-French foreign policy. He converted to Roman Catholicism  to maintain his influence in James�s reign. After William became king,  Sunderland renounced his Catholicism and became the principal interme�  diary between the king and Parliament. He was appointed lord chamber-  lain in 1697, but Whig opposition soon forced him from office.</p><p>sundew Any of about 100 species of annual and perennial flowering  carnivorous plants in four genera, notably Drosera, that make up the fam�  ily Droseraceae (sundew family).

Both  leaf surfaces are generally covered with sticky, gland-tipped hairs and  sensitive tentacles that trap insects. After the trapped prey has been  digested by enzymes secreted by the tentacles, the leaf reopens, resetting  the trap. The best-known sundew is the Venus's-flytrap. See also pitcher  PLANT.</p><p>Sundiata \sun-�ja-t9\ (d. 1255) Monarch of the ancient Mali empire in  West Africa. After organizing a private army and consolidating his posi�  tion among his own Malinke people, Sundiata launched attacks against  neighbouring states in the 1230s. In 1240 he seized and razed Kumbi, the  last capital of the ancient Ghana empire. During his reign over Mali he  established its territorial base and laid the foundations for its future pros�  perity and political unity.</p><p>sunfish Any of numerous species o  carnivorous freshwater fishes placed  with the crappies and black basses in  the family Centrarchidae. Usually  less than 8 in. (20 cm) long, sun-  fishes are fine food and game fishes.</p><p>The best-known are the black-  banded sunfish ( Enneacanthus cha-  etodon) of the eastern U.S. and the  bluegill ( Lepomis macrochirus),  which has an orange belly and blue  markings. The longear sunfish has  orange spots and wavy, bright blue  streaks. The pumpkinseed, or com�  mon sunfish, has an orange belly and  a red spot on its ear. The rock bass  has irregular dark markings.</p><p>sunflower Any of 60 species of  annual herbaceous plants in the  genus Helianthus (composite family),  native mostly to North and South  America. The common sunflower  (H. annuus ) has a rough, hairy stem  3�15 ft (1^1.5 m) high; broad,  coarsely toothed, rough leaves 3-12  in.

The leaves are used as fodder, the flowers yield a yellow dye, and  the seeds contain oil and are used for food. The oil is used for cooking,  as an ingredient of soaps and paints, and as a lubricant. Only a few spe�  cies are cultivated, some for their spectacular size.</p><p>Sung-chiang See Songjiang  Sung dynasty See Song dynasty  Sung-hua Chiang See Sungari River</p><p>Sungari \ 1 suq-g3- , re\ River Chinese Songhua Vsurj-'hwaV Jiang or  Sung-hua Chiang River, northeastern China. Rising in the Changbai  Mountains, it is joined by its chief tributary, the Nen River, before it enters  the Amur River 1,197 mi (1,927 km) later. The Amur�s largest tributary, it  passes through a fertile plain and is navigable for much of its course.</p><p>sunna \'su-no\ Body of traditional social and legal custom and practice  that constitutes proper observance of Islam. Early Muslims did not concur  on what constituted sunna, because of the wide variety of pre-Islamic prac�  tices among converted peoples that had to be assimilated, reconciled, or  abandoned. In the 8th century the sunna of Muhammad, as preserved in eye�  witness records, was codified as the Hadith by AbO �Abd Allah Shaf'iI. Later  Muslim scholars strengthened the authority of sunna by devising a system  for attesting the authenticity of various practices claimed as descending  from Muhammad. See also �ilm al-hadith; isnad; SharI'ah; tafsIr.</p><p>Sunnite \'su-,nlt\ Larger of the two major divisions of Islam, compris�  ing 90% of the world�s Muslims. Sunnites regard theirs as the mainstream  and traditionalist branch of Islam, as distinguished from the minority  branch, the SHfiTEs. Sunnites recognize the first four Umayyad caliphs (see  Umayyad dynasty) as Muhammad�s rightful successors. Because the Sun�  nites understood Muhammad�s theocratic state to have been an earthly,  temporal dominion, they were willing to accept unexceptional and even  foreign caliphs, provided order and religious orthodoxy were maintained.  Sunnite orthodoxy emphasizes consensus based on the views and customs  of the majority of the community, thereby enabling them to incorporate  various customs and usages that arose historically but that had no roots  in the Qur�an. Sunnites recognize the six authentic books of the HadIth  and accept the four major schools of Islamic law. In the early 21st cen�  tury, Sunnite Muslims numbered about one billion.</p><p>Sunnyvale City (pop., 2000: 131,760), western California, U.S. Sunny�  vale was settled in 1850 and was incorporated in 1912. It was originally  a fruit-processing centre; its economic base shifted when the U.S. Navy  built a dirigible base nearby in the 1930s and the Joshua Hendy Iron  Works (later Westinghouse Electric Corp.) expanded in 1942. Its popula�  tion grew rapidly in the 1960s. Chief manufactures include guided mis�  siles.</p><p>Sunset Crater Volcano National Monument Preserve, north-  central Arizona, U.S. Established in 1930, the monument covers 5 sq mi  (13 sq km) and contains the brilliant-hued cinder cone of an extinct vol�  cano that erupted c. 1064. It rises 1,000 ft (300 m) and has a crater 400  ft (120 m) deep and 1,280 ft (390 m) in diameter. The tract contains  numerous lava flows, fumaroles, and lava beds.</p><p>sunspot Cooler-than-average region of gas on the Sun�s surface asso�  ciated with strong local magnetic activity. Sunspots appear as dark spots,  but only in contrast with the surrounding photosphere, which is several  thousand degrees hotter. Spots several times larger than Earth are visible  to the unaided eye (viewed through a filter); very small ones are hard to  see even with a telescope. They come and go as part of the solar cycle,  usually in pairs or groups, and may last for months; their cause appears  to be related to the magnetic field reversals that occur every 11 years. The  reality of these apparent flaws in the Sun was generally accepted only c.  1611. Periods of high sunspot activity are associated on Earth with  brighter auroras and interference with radio signals.</p><p>SUNY See State University of New York</p><p>Sunzi or Sun-tzu \'sun-'dzu\ (fl. 5th century bc) Chinese military strat�  egist. A general who served the state of Wu late in the Spring and Autumn  period (770-476 bc), he is traditionally regarded as the author of the ear�  liest known treatise on war and military science, The Art of War , though  it was more likely written early in the Warring States period (475-221 bc).  A systematic guide to strategy and tactics, it discusses various maneuvers</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1846 I Super Bowl &#x25BA; supply and demand</p><p>and the effect of terrain, stresses the importance of accurate information  about the enemy�s forces, and emphasizes the unpredictability of battle  and the need for flexible responses. Its insistence on the close relation�  ship between political considerations and military policy influenced mod�  ern strategists, notably Mao Zedong.</p><p>Super Bowl Annual championship game of the National Football  League. It is played by the winners of the league�s American Football  Conference and National Football Conference. The first Super Bowl com�  petition was held in 1967. It normally falls in January, usually on the last  Sunday, and is watched by more Americans than any other sporting event.</p><p>supercharger Air compressor or blower used in piston-type internal-  combustion engines to increase the amount of air drawn into the cylinders  by the movement of the pistons during each intake stroke. With the addi�  tional air, more fuel is burned, and the engine�s power is increased. In  aircraft engines, supercharging compensates for the reduced atmospheric  pressure at high altitudes. Development of the gas turbine, which requires  a constant flow of air and fuel, led to the turbosupercharger, a centrifugal  blower driven by a small gas turbine powered by the exhaust gases from  the engine cylinders.</p><p>supercomputer Any of a class of extremely powerful digital comput�  ers. The term is commonly applied to the fastest high-performance sys�  tems available at a given time; current personal computers are more  powerful than the supercomputers of just a few years ago. Supercomput�  ers are used primarily for scientific and engineering work. Unlike con�  ventional computers, they usually have more than one CPU, often  functioning in parallel (simultaneously); even higher-performance super�  computers are now being developed through use of massively parallel  processing, incorporating thousands of individual processors. Supercom�  puters have huge storage capacity and very fast input/output capability,  and can operate in parallel on corresponding elements of arrays of num�  bers rather than on one pair of elements at a time.</p><p>superconductivity Almost total lack of electrical resistance in certain  materials when they are cooled to a temperature near absolute zero. Super�  conducting materials allow low power dissipation, high-speed operation,  and high sensitivity. They also have the ability to prevent external mag�  netic fields from penetrating their interiors and are perfect diamagnets (see  diamagnetism). Since it was first discovered in mercury by Heike Kamerlingh  Onnes in 1911, similar behaviour has been found in some 25 other chemi�  cal elements and in thousands of alloys and compounds. Superconductors  have applications in medical imaging, magnetic energy-storage systems,  motors, generators, transformers, computer components, and sensitive  magnetic-field measuring devices.</p><p>superego In Freudian psychoanalytic theory, one of the three aspects  of the human personality, along with the id and the ego. The last of the  three elements to develop, the superego is the ethical component of the  personality, providing the moral standards by which the ego operates. The  superego is formed during the first five years of life in response to paren�  tal punishment and approval; children internalize their parents� moral  standards as well as those of the surrounding society, and the developing  superego serves to control aggressive or other socially unacceptable  impulses. Violation of the superego�s standards gives rise to feelings of  guilt or anxiety.</p><p>superfluidity Unusual property of liquid helium cooled below -455.75  �F (-270.97 �C). At such low temperatures, helium exhibits an enormous  rise in heat conductivity and rapid flow through capillaries or over the rim  of its container. To explain such behaviour, the substance is described in  terms of a �two-fluid� mixture model consisting of normal helium and  superfluid helium. In normal helium the atoms are in excited states (see  excitation), whereas in superfluid helium they are in their ground state. As  the temperature is lowered below -455.75 �F, more of the helium becomes  superfluid. It is assumed that the superfluid component can move through  the container without friction, thereby explaining the unusual behaviour.</p><p>Superfund U.S. government fund intended to pay for the cleanup of  hazardous-waste dump sites and spills. The 1980 act creating it called for  financing by a combination of general revenues and taxes on polluting  industries. The Environmental Protection Agency was directed to create a  list of the most dangerous sites; it would then compel the polluter to pay  for the cleanup or would pay for the cleanup itself through the Superfund  and sue for reimbursement. By the 1990s the Superfund had received bil�  lions of dollars, and work had begun on many sites. In response to wide�</p><p>spread charges of waste, mismanagement, and inefficiency, the Superfund  streamlined its procedures, and by the beginning of the 21st century clean�  ups at more than 750 sites had been completed. In the early 21st century,  various proposals were introduced to alter the financing of the Superfund.  See also Love Canal.</p><p>supergiant star Star of very great natural luminosity and relatively  enormous size, typically several magnitudes brighter and several times  larger than a giant star. Like other classes of stars, they are distinguished  in practice by examination of certain lines in their spectra (see spectros�  copy). A supergiant may have a diameter several hundred times that of the  Sun and a luminosity nearly a million times as great. Supergiants live  probably only a few million years, an extremely short life for a star.</p><p>Superior, Lake Lake, U.S. and Canada. The largest of the five Great  Lakes, Superior is the world�s largest freshwater lake. It is 383 mi (616  km) long and 160 mi (258 km) at its widest, with an area of 31,800 sq  mi (82,362 sq km) and depths reaching 1,330 ft (405 m). Lake Superior  is known for its picturesque coastline and its numerous shipwrecks; its  islands include Isle Royale. The head of the Great Lakes-SAINT Lawrence  Seaway system, it is connected to Lake Huron at its southeastern end via  the Sault Ste. Marie locks. Ships transport grain, flour, and iron ore dur�  ing the eight-month navigation season. The French Jesuit missionary  Claude-Jean Allouez charted the lake in 1667. The region came under  British control (1763-83) and remained in British hands until 1817, when  the American Fur Co. took over south of the Canadian border.</p><p>supermarket Large retail store operated on a self-service basis, sell�  ing groceries, produce, meat, bakery and dairy products, and sometimes  nonfood goods. Supermarkets were first established in the U.S. during the  1930s as no-frills retail stores offering low prices. In the 1940s and �50s  they became the major food marketing channel in the U.S.; the 1950s also  saw them spread through much of Europe. Their growth is part of a trend  in developed countries toward reducing cost and simplifying marketing. In  the 1960s supermarkets began appearing in developing countries in the  Middle East, Asia, and Latin America, where they appealed to individu�  als who had the necessary buying power and food storage facilities.</p><p>supernova Any of a class of violently exploding stars whose luminos�  ity after eruption suddenly increases many millions of times above its  normal level. Like novas, supernovas undergo a tremendous, rapid bright�  ening lasting a few weeks, followed by a slow dimming, and show blue-  shifted emission lines on spectroscopy, which implies that hot gases are  blown outward. Unlike a nova, a supernova explosion is a catastrophic  event for a star, leading to its collapse into a neutron star or back hole.  Amounts of its matter equal to the mass of several Suns may be blasted  into space with such energy that the exploding star outshines its entire  home galaxy. Only seven supernovas are known to have been recorded  before the 17th century, the most famous in ad 1054; its remnants are  visible today as the Crab Nebua. The closest and most studied supernova  in modem times is SN 1987A, which appeared in 1987 in the Large  Magelanic Cloud. Supernova explosions release not only tremendous  amounts of radio energy and X-rays but also cosmic rays; in addition, they  create and fling into interstellar space many of the heavier elements found  in the universe, including those forming Earth�s solar system.</p><p>supervenience \,su-p9r-'ven-y3ns\ In philosophy, the asymmetrical  reation of ontological dependence that holds between two generically  different sets of properties (e.g., mental and physical properties) if and  only if every change in an object�s properties belonging to the first set�  the supervening properties�entails and is due to a change in properties  belonging to the second set (the base properties). Supervenience has often  been appealed to by philosophers who want to uphold physicalism while  rejecting the identity theory: Though it may be impossible to identify men�  tal properties with physical properties in a one-to-one fashion, mental  properties may still supervene on, and thus be grounded in, physical prop�  erties. Thus, no two things that are physically alike can be mentally (or  psychologically) different, and a being�s mental properties will be deter�  mined by its physical ones.</p><p>supply and demand Relationship between the quantity of a com�  modity that producers have available for sale and the quantity that con�  sumers are willing and able to buy. Demand depends on the price of the  commodity, the prices of related commodities, and consumers� incomes  and tastes. Supply depends not only on the price obtainable for the com�  modity but also on the prices of similar products, the techniques of pro�  duction, and the availability and costs of inputs. The function of the market</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>supply-side economics &#x25BA; surfing I 1847</p><p>is to equalize demand and supply through the price mechanism. If buy�  ers want to purchase more of a commodity than is available on the mar�  ket, they will tend to bid the price up. If more of a commodity is available  than buyers care to purchase, suppliers will bid prices down. Thus, there  is a tendency toward an equilibrium price at which the quantity demanded  equals the quantity supplied. The measure of the responsiveness of sup�  ply and demand to changes in price is their elasticity.</p><p>supply-side economics Theory that focuses on influencing the sup�  ply of labour and goods, using tax cuts and benefit cuts as incentives to  work and produce goods. It was expounded by the U.S. economist Arthur  Laffer (b. 1940) and implemented by Pres. Ronald Reagan in the 1980s.  Supporters point to the economic growth of the 1980s as proof of its effi�  cacy; detractors point to the massive federal deficits and speculation that  accompanied that growth.</p><p>suprarenal gland See adrenal gland</p><p>Supremacy, Act of (1534) English act of Parliament that recognized  Henry VIII as the �Supreme Head of the Church of England.� The act also  required an oath of loyalty from English subjects that recognized his mar�  riage to Anne Boleyn. It was repealed in 1555 under Mary I, but in 1559  Parliament adopted a new Act of Supremacy during the reign of Elizabeth I.</p><p>Suprematism First movement of pure geometrical abstraction in art,  introduced in Russia c. 1913. Originated by Kazimir Malevich and dissemi�  nated by El Lissitzky and the Bauhaus school, it had far-reaching influence  on Western art and design. Malevich aimed to convey the �supremacy of  feeling in art,� which he believed could be expressed through the simplest  of visual forms. He exhibited the first Suprematist compositions in 1915,  the year he issued the Suprematist manifesto. The purest embodiment of  Suprematist ideals can be seen in his White on White series (1917-18).</p><p>Supreme Court of the United States Final court of appeal in the  U.S. judicial system and final interpreter of the Constitution of the United  States. The Supreme Court was created by the Constitutional Convention  of 1787 as the head of a federal court system, though it was not formally  established until Congress passed the Judiciary Act in 1789. It was granted  authority to act in cases arising under the Constitution, laws, or treaties  of the U.S.; in controversies to which the U.S. is a party; in controver�  sies between states or between citizens of different states; in cases of  admiralty and maritime jurisdiction; and in cases affecting ambassadors  or other ministers or consuls. Its size, which is set by Congress, varied  between 6 and 10 members before being set at 9 in 1869. Justices are  appointed by the president but must be confirmed by the Senate. The court  has exercised the power of judicial review since 1803, when it first declared  part of a law unconstitutional in Marburyw. Madison, though the power is  not explicitly granted to it by the Constitution. Though the court can  sometimes serve as a trial court through its original jurisdiction, relatively  few cases reach the court in this manner; most cases arise by appeal or  by certiorari. Among the most important doctrinal sources used by the  Supreme Court have been the commerce, due-process, and equal-protection  clauses of the Constitution. It also has often ruled on controversies involv�  ing civil liberties (see civil liberty), including freedom of speech and the right  of privacy. Much of its work consists of clarifying, refining, and testing  the Constitution�s philosophic ideals and translating them into working  principles.</p><p>Supremes U.S. pop-soul vocal trio. The original Supremes�Diana  Ross (byname of Diane Earle; b. 1944), Mary Wilson (b. 1944), and Flo�  rence Ballard (1943-76)�began recording for Motown (as The  Primettes) on graduating from high school in Detroit, Mich. Their long  string of Motown hits in the mid-1960s, many written by Brian and Eddie  Holland and Lamont Dozier, began with �Where Did Our Love Go?� and  included �Baby Love� and �Stop! In the Name of Love.� In 1966 Bal�  lard was replaced with Cindy Birdsong (b. 1939). Ross left the Supremes  in 1969, and Wilson left in 1977. Ballard died in relative poverty of car�  diac arrest. Ross�s highly successful solo career included film roles (nota�  bly in Lady Sings the Blues, 1972) and a free 1983 Central Park concert  that drew an audience of record-setting size.</p><p>Sur See Tyre</p><p>Surabaya \ 1 sur-3-'bI-3\ Seaport city (pop., 1995 est.: 2,701,000), north�  eastern coast of Java, Indonesia. It is Indonesia�s second-largest city and  has been eastern Java�s chief trading center since the 14th century. The  Dutch gained control in the 18th century and built their main East Indies  naval base there. Occupied by the Japanese in World War II, it suffered</p><p>heavy damage; it was damaged again during Indonesia�s war for inde�  pendence (1945�49). It is the site of Indonesia�s main naval base and a  naval college, and of Airlangga University (1954).</p><p>surah or sura Any chapter of the Qur�an. According to Muslim belief,  each of the 114 surahs, which vary in length from several lines (known  as ayahs) to several pages, encompasses one or more divine revelations  of Muhammad. All but three lines are in the form of a direct address from  God. The tone of each varies but is generally moralistic, demanding obe�  dience to a transcendent but compassionate God. Except for the opening  surah, known as fdtihah (the �opening�), they are arranged in descend�  ing order of length and numbered serially. They carry conventional names  (e.g., Cow, Spider, Blood Clot) deriving from some image contained in  them that is not necessarily indicative of their meaning or theme.</p><p>Surat Vsur-st, s3-'rat\ City (pop., 2001: 2,433,835), southeastern Gujarat  state, west-central India. It is near the mouth of the Tapti River and the Gulf  of Khambhat (Cambay). A major seaport from the 16th century, it was  conquered by the Mughals in 1573 and was twice sacked by the Marathas  in the 17th century. It became a centre for textile manufacturing and ship�  building. The British established their first factory (trading post) in India  there c. 1612, marking the beginning of the British imperial presence in  India. The city declined in the 18th century but prospered again with the  opening of India�s railways. Surat�s cottons, silks, brocades, and objects  of gold and silver are still famous.</p><p>surface In geometry, a two-dimensional collection of points (flat sur�  face), a three-dimensional collection of points whose cross section is a  curve (curved surface), or the boundary of any three-dimensional solid.  In general, a surface is a continuous boundary dividing a three-  dimensional space into two regions. For example, the surface of a sphere  separates the interior from the exterior; a horizontal plane separates the  half-plane above it from the half-plane below. Surfaces are often called  by the names of the regions they enclose, but a surface is essentially two-  dimensional and has an area, while the region it encloses is three-  dimensional and has a volume. The attributes of surfaces, and in particular  the idea of curvature, are investigated in differential geometry.</p><p>surface Outermost layer of a material or substance. Because the par�  ticles (atoms or molecules) on the surface have nearest neighbours beside  and below but not above, the physical and chemical properties of a sur�  face differ from those of the bulk material; surface chemistry is thus a  branch of physical chemistry. The growth of crystals, the actions of cata�  lysts and detergents, and the phenomena of adsorption, surface tension, and  capillarity are aspects of behaviour at surfaces. The appearance of the sur�  face, whether achieved with electroplating, paint, oxidation-reduction,  bleaching (see bleach), or another means, is aesthetically important.</p><p>surface integral In calculus, the integral of a function of several vari�  ables calculated over a surface. For functions of a single variable, definite  integrals are calculated over intervals on the x-axis and result in areas. For  functions of two variables, the simplest double integrals are calculated over  rectangular regions and result in volumes. More generally, an integral cal�  culated over a plane or curved surface results in a surface integral repre�  senting a volume, though it also has many nongeometric applications.</p><p>surface tension Property of a liquid surface that causes it to act like  a stretched elastic membrane (see elasticity). Its strength depends on the  forces of attraction among the particles of the liquid itself and with the  particles of the gas, solid, or liquid with which it comes in contact. Sur�  face tension allows certain insects to stand on the surface of water and  can support a razor blade placed horizontally on the liquid�s surface, even  though the blade may be denser than the liquid and unable to float. Sur�  face tension results in spherical drops of liquid, as the liquid tends to  minimize its surface area.</p><p>surfing Sport of riding breaking waves toward the shore, especially with  a surfboard. The sport originated prehistorically in the South Seas. In 1777  and 1778 Capt. James Cook first reported seeing surfers in Tahiti and on  Oahu. In 1821 surfing was banned by missionaries who thought it  immoral. It was revived in the 1920s by the Hawaiian swimmer Duke  Kahanamoku (1890-1968). Today surfing is enjoyed on beaches with  breakers throughout the world, and several international championships  are held. The goal is to maneuver on the unbroken face of the wave, pref�  erably as far back toward the curl (�tube�) as possible. In addition to surf�  boards, surfers can use belly-boards, kneeboards, or kayaks, or they can  bodysurf using no board at all.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1848 I surgeonfish &#x25BA; Surrey</p><p>surgeonfish or tang Any of about 75 species (family Acanthuridae)</p><p>of thin, deep-bodied, tropical marine  fishes that are small-scaled, with a  single dorsal fin and one or more dis�  tinctive, sharp spines on either side  of the tail base. The spines resemble  a surgeon�s scalpel and may be either  fixed or hinged at the rear so that  they can be opened outward and  directed forward. Surgeonfishes are  mostly algae eaters and usually do  not exceed 20 in. (50 cm) long. The  yellow surgeon, or yellow tang  (Zebrasoma flavescens), is an Indo-  Pacific species, and the blue tang  (Acanthurus coeruleus ) is found in  the Atlantic and Caribbean.</p><p>Surgeonfish (Acanthurus leucosternon)</p><p>JANE BURTON-BRUCE COLEMAN LTD.</p><p>surgery Branch of medicine concerned with treatment by physical  means rather than drugs. In addition to operations requiring access to the  inside of the body (open surgery), it includes manipulation from outside  the body (e.g., setting of a broken bone, skin grafts). Modern surgery  began in the mid-19th century with use of anesthetics and antiseptics. Other  important advances have included diagnostic imaging, blood typing, intu�  bation to support breathing, intravenous administration of fluids and  drugs, heart-lung machines (see artificial heart), endoscopy, and devices  that monitor body functions. Specialized instruments used in surgery  include scalpels to cut tissue, forceps to hold blood vessels closed or grasp  and manipulate structures, clamps to immobilize or crush tissues, gauze  sponges to absorb fluids and keep an area dry, retractors to hold incisions  open, and curved needles to suture them closed. Pre- and postoperative  care is crucial to the success of surgery.

Reli�  gions: Christianity (Roman Catholic, Protestant, other Christians), Hin�  duism, Islam, traditional beliefs. Currency: Suriname dollar. Suriname has  a low, narrow coastal plain, inland savannas, a forested plateau region,</p><p>and mountain ranges. A number of major rivers, including the Couran-  tyne, Maroni, and Suriname, cross the country to empty into the Atlantic.  Bauxite mining, aluminum production, and agriculture are the largest sec�  tors of the economy. Exports include rice, bananas, sugarcane, oranges,  and shrimp. Suriname is a republic with one legislative house; its head  of state and government is the president. It was inhabited by various South  American Indian peoples prior to European settlement. Spanish explor�  ers claimed Suriname in 1593, but the Dutch began to settle there in 1602,  followed by the English in 1651. It was ceded to the Dutch in 1667, and  in 1682 the Dutch West India Company introduced coffee and sugarcane  plantations and African slaves to cultivate them. Slavery was abolished  in 1863, and indentured servants were brought from China, Java, and India  to work the plantations, adding to the ethnic mix of the population. Except  for brief interludes of British rule (1799-1802, 1804-15), Suriname  remained a Dutch colony. It gained internal autonomy in 1954 and inde�  pendence in 1975. A military coup in 1980 ended civilian control until the  electorate approved a new constitution in 1987. Military control resumed  after a coup in 1990.

Surrealism grew principally out  of the earlier Dada movement, which before World War I produced works  of anti-art that deliberately defied reason; Surrealism developed in reac�  tion against the �rationalism� that had led to World War I. The movement  was founded in 1924 by Andre Breton as a means of joining dream and  fantasy to everyday reality to form �an absolute reality, a surreality.�  Drawing on the theories of Sigmund Freud, he concluded that the uncon�  scious was the wellspring of the imagination. Breton was a poet, but Sur�  realism�s major achievements were in painting. Some artists practiced  organic, emblematic, or absolute Surrealism, expressing the unconscious  through suggestive yet indefinite biomorphic images (e.g., Jean Arp, AAax  Ernst, Andre Masson, Joan Miro). Others created realistically painted  images, removed from their context and reassembled within a paradoxi�  cal or shocking framework (Salvador Dali, Rene Magritte). With its empha�  sis on content and free form. Surrealism provided a major alternative to  the contemporary, highly formalistic Cubist movement and was largely  responsible for perpetuating in modern painting the traditional emphasis  on content.</p><p>Surrey Administrative county (pop., 2001: 1,059,015) and historic  county, southern England. Surrey is located southwest of London. Sheep  raising was an important medieval activity for the county, and by the 16th  century a cloth trade was also growing. Its forested hills were a source of  timber for charcoal, construction, and shipbuilding. Transport of these  products, originally dependent on rivers, was facilitated in 1801 when the  Surrey Iron Railway was established as the first public railway. During  the 19th century the world�s densest network of suburban railways devel�  oped in northern Surrey. Suburban growth continued after World War II,  proceeding under planning restraints. The county seat is Guildford.</p><p>Surrey, Henry Howard, earl of (b. 1517, Hunsdon, Hertfordshire,  Eng.?�d. Jan. 13, 1547, London) English poet. Because of his aristo�  cratic birth and connections, Surrey was involved in the jockeying for  place that accompanied Henry VIII�s policies. After returning to England  in 1546 from a campaign abroad, he was accused of treason by his rivals.  After his sister admitted he was still a Roman Catholic, he was executed  at age 30. Most of his poetry was published 10 years later. With Thomas  Wyat, he introduced into England the styles and metres of the Italian  humanist poets, laying the foundation of a great age in English poetry. He  translated two books of Virgil�s Aeneid, marking the first use in English  of blank verse and was the first to develop the sonnet form used by Wil�  liam Shakespeare.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>surrogate motherhood &#x25BA; Sutherland I 1849</p><p>surrogate motherhood Practice in which a woman (the surrogate  mother) bears a child for a couple unable to produce children, usually  because the wife is infertile or unable to carry a pregnancy to term.

In 1831 he launched New  Sporting Magazine. His famous comic character Mr. Jorrocks, a blunt  Cockney grocer entirely given over to fox hunting, appeared in Jorrocks�s  Jaunts and Jollities (1838), Handley Cross (1843), and Hillingdon Hall  (1845).

Its principal modern uses are in the fields  of transportation, building, land use, and communications. Surveying is  divided into the categories of plane surveying (mapping small areas) and  geodetic surveying (mapping large areas of the globe). The Romans are  said to have used the plane table, which consists of a drawing board  mounted on a tripod or other support and a straightedge along which lines  are drawn. It was the first device capable of recording or establishing  angles. With the publication of logarithmic tables in 1620, portable angle�  measuring instruments, called topographic instruments, or theodolites,  came into use; they included pivoted arms for sighting and could be used  for measuring both horizontal and vertical angles. Two revolutionary  20th-century innovations were photogrammetry (mapping from aerial  photographs) and electronic distance measurement, including the use of  the laser.</p><p>Surveyor Any of a series of seven unmanned U.S. space probes sent  to make soft landings on the Moon in 1966-68.

In the 1930s he  helped supervise the Stalinist purges in the Urals and Ukraine. Later a  leading official in the Caucasus, he supervised the deportation of ethnic  minorities in World War II. He was appointed to the Politburo in 1952,  and from 1955 he held a pivotal position in the ruling clique. A political  conservative, he helped Nikita Khrushchev quell a conspiracy in the Polit�  buro in 1957, but he organized the bloodless coup in 1964 that ousted  Khrushchev and substituted Leonid Brezhnev. Thereafter, he concentrated  on relations between the Soviet Communist Party and other communist  parties around the world.</p><p>suspension, automobile Elastic members designed to cushion the  impact of road irregularities on a portion of an automotive vehicle. The  members link the vehicle�s tires with its suspended portion, and usually  consist of springs and shock absorbers. Spring elements used for auto�  mobile suspension members include (in increasing order of ability to store  elastic energy per unit of weight) leaf springs, coil springs, torsion bars,  rubber-in-shear devices, and air springs. The springs absorb the energy of  impacts of the tires along the road surface, and the shocks damp or dis�  sipate that energy, using hydraulics, so that the suspended portion of the  vehicle does not keep bouncing.

His early work was characterized by an exacting repre-  sentationalism that evolved into Surrealism. He turned primarily to paint�  ing c. 1935 and served as official war artist 1940-45; his war paintings  are an evocative record of desolation. His �thorn period� began with his  Crucifixion (1946), considered to be one of the most important religious  paintings of the 20th century. In such late works he incorporated anthro�  pomorphic insect and plant forms, particularly thorns, which he trans�  formed into powerful, frightening totemic images. Sutherland was known,  too, for his expressionistic, penetrating portraits.

In his General History of Insects he accurately described and  illustrated the life histories and anatomy of many insect species and clas�  sified insects into four major divisions, three of which have been more  or less retained in modern classification. He studied tadpole and adult frog  anatomy and described the ovarian follicles of mammals. His improved  techniques for injecting wax and dyes into cadavers had important con�  sequences for the study of human anatomy. He showed that muscles alter  in shape but not in size during contraction.</p><p>swamp Freshwater wetland ecosystem characterized by poorly drained  mineral soils and plant life dominated by trees.

It is used widely throughout the  world as a symbol of prosperity and good fortune. In India, it continues  to be the most common auspicious symbol of Hindus and Jains, as well  as for Buddhists, for whom it symbolizes the Buddha�s feet or footprints.  In China and Japan, where it traveled with the spread of Buddhism, it has  been used to denote plurality, prosperity, and long life. It occurs as a motif  in early Christian and Byzantine art, as well as in Maya and Navajo art.  The counterclockwise swastika, suggested as a general anti-Semitic sym�  bol in 1910 by the German poet and nationalist Guido von List, was  adopted as the symbol of the Nazi Party at its founding in 1919-20.</p><p>Swazi Vswa-ze\ or Swati Vswa-te\ Bantu-speaking people inhabiting  the grasslands of Swaziland and neighbouring regions of South Africa and  Mozambique.

Among waterfowl,  swans are the largest and fastest,  both swimming and flying; at about  50 lbs (23 kg), the mute swan (C.  olor ) is the heaviest flying bird.  Swans dabble in shallows for aquatic  plants. Five all-white, black-legged  species live in the Northern Hemi�  sphere; a black and a black-necked  species live in the Southern Hemi�  sphere. Males (cobs) and females  (pens) look alike. Swans mate for  life. The cob keeps guard while the  pen incubates, on average, six eggs  on a heap of vegetation; the young  (cygnets) are tended for several  months.

Mineral resources include asbestos and diamonds. Swa�  ziland is a monarchy with two legislative houses; its head of state and  government is the king, assisted by the prime minister. Stone tools and  rock paintings indicate prehistoric habitation in the region, but it was not  settled until the Bantu- speaking Swazi people migrated there in the 18th  century and established the nucleus of the Swazi nation. The British  gained control in the 19th century after the Swazi king sought their aid  against the Zulu. Following the South African War, the British governor  of Transvaal administered Swaziland; his powers were transferred to the  British high commissioner in 1906. In 1949 the British rejected the Union  of South Africa�s request to control Swaziland. The country gained lim�  ited self-government in 1963 and achieved independence in 1968. In the  1970s new constitutions were framed based on the supreme authority of  the king and traditional government. Although the kingdom remained in  place in the early 21st century, steps were being taken to establish a con�  stitution. Swaziland has one of the highest rates of HIV infection in the  world, with some two-fifths of the population infected.</p><p>sweat gland Either of two types of perspiration glands in the skin.  Eccrine sweat glands, controlled by the sympathetic nervous system, use  evaporation to cool the skin by secreting water when body temperature  rises. Apocrine sweat glands, usually associated with hair follicles, are  concentrated in the underarms and genital region. Starting at puberty, hor�  mones stimulate them to continuously secrete a fatty sweat.

Area: 173,860 sq mi (450,295 sq km).  Population (2005 est.): 9,024,000. Capital: Stockholm. The population is  largely homogeneous, although there are Finnish and Sami (Lapp) minori�  ties and 10% of the inhabitants are immigrants or their descendents. Lan�  guage: Swedish (official). Religions: Christianity (predominantly  Protestant; also Roman Catholic); also Islam. Currency: Swedish krona.  Sweden has three traditional regions: mountainous Norrland covers about  three-fifths of the country and has vast forests and large ore deposits;  Svealand has undulating glacial ridges and contains most of the country�s  90,000 lakes; and Gotaland comprises the stony Smaland highlands and  the rich Skane plains. About 15% of Sweden lies north of the Arctic Circle.  The economy is largely based on services, heavy industries, and interna�  tional trade. Sweden has large deposits of iron ore; industries include  mining, lumbering, steel manufacturing, and tourism. Agricultural prod�  ucts include grains, sugar beets, potatoes, and livestock. One of the  world�s richest countries, Sweden is known for its comprehensive social  welfare system. It is a constitutional monarchy and parliamentary state  with one legislative house; its chief of state is the king, and the head of  government is the prime minister. The first traces of human life in Swe�  den date from about 9000 bc. During the Viking era (9th-10th century ad),  the Swedes controlled river trade in eastern Europe between the Baltic  Sea and the Black Sea; they also raided western European lands. Sweden  was loosely united and Christianized in the 11th- 12th century. It con�  quered the Finns in the 12th century, and in the 14th century it united  with Norway and Denmark under a single monarchy. Sweden broke away  in 1523 under Gustav I Vasa. In the 17th century it emerged as a great  European power in the Baltic region, but its dominance declined after its  defeat in the Second Northern War (1700-21). It became a constitutional  monarchy in 1809 and united with Norway in 1814; it acknowledged  Norwegian independence in 1905. Sweden maintained its neutrality dur�  ing both World Wars. It was a charter member of the UN but abstained  from membership in NATO and did not join the European Union until  1995. A new constitution drafted in 1975 reduced the monarch�s powers  to those of a ceremonial chief of state. In 1997 Sweden began the con�</p><p>troversial shutdown of its nuclear power  industry. By the early 21st century it had  emerged as a European centre of telecom�  munications and information technology.</p><p>Swedenborg, Emanuel (b. Jan. 29, 1688, Stockholm, Swed.�d.  March 29, 1772, London, Eng.) Swedish scientist, theologian, and mys�  tic. After graduating from the University of Uppsala, he spent five years  abroad studying the natural sciences. On his return he began publication  of Sweden�s first scientific journal, Daedelus Hyperboreas, and Charles  XIII appointed him assessor with the Royal Board of Mines. His writing  gradually shifted toward philosophy of nature and metaphysics, in concert  with his growing belief that the universe had a basically spiritual struc�  ture. In 1744 he had a vision of Christ, and in 1745 he received a call to  abandon worldly learning. He spent the rest of his career interpreting the  Bible and relating what he had seen in his visions. He maintained that  God was the power and life within all creatures and that the Christian  Trinity represented the three essential qualities of God: love, wisdom, and  activity. He believed redemption consisted in humankind�s being recre�  ated in God�s image through Christ�s glorification. He published more  than 30 works, including The True Christian Religion (1771). Societies  were soon founded to propagate his pantheistic teaching, notably the New  Jerusalem Church, established in London in 1787. Swedenborgians came  to the U.S. in the 1790s.

Modem Swedish is usually dated  from 1526, when a translation of the  New Testament was first printed. The  standard language began to emerge  in the 17th century, based largely on  the Svea dialects spoken in Stock�  holm.

The fastest of small birds, swifts can fly at 70 mph (110 kph).  They are 4-9 in. (9-23 cm) long and have long wings, a chunky dark  body, a broad head, and a short, wide, slightly curved bill. The tail may  be short or long and deeply forked. Swifts capture insects, drink, bathe,  and sometimes mate on the wing. The feet, incapable of perching, are  used to cling to vertical surfaces. Swifts use their sticky saliva to glue the  nest to a cave wall, the inside of a chimney, or a tree hollow.</p><p>Swift, Gustavus Franklin (b. June 24, 1839, West Sandwich, Mass.,  U.S.�d. March 29, 1903, Chicago, Ill.) U.S. meatpacker. Swift started as  a butcher�s helper at age 14 and by 1859 was operating his own butcher  shop. In 1872 he became the partner of a Boston meat dealer; three years  later he transferred their cattle-buying operations to Chicago. Believing  profits would increase if fresh meat rather than live cattle were shipped  from Chicago, he had a refrigerator car designed and made his first ship�  ment in 1877. With his brother he formed Swift &amp; Co. (1885). During his  18 years as president, its capitalization rose from $300,000 to $25 mil�  lion. Like his rivals Philip D. Armour and Nelson Morris, Swift was a leader  in byproduct utilization, entering related businesses such as soap, glue,  fertilizer, and margarine.</p><p>Swift, Jonathan (b. Nov. 30, 1667, Dublin, Ire.�d. Oct. 19, 1745,  Dublin) Irish author, the foremost prose satirist in English. He was a stu�  dent at Dublin�s Trinity College during the anti-Catholic Revolution of  1688 in England. Irish Catholic reaction in Dublin led Swift, a Protestant,  to seek security in England, where he spent various intervals before 1714.  He was ordained an Anglican priest in 1695. His first major work, A Tale of</p><p>a Tub (1704), comprises three satiric  sketches on religion and learning; he  also became known for religious and  political essays and impish pam�  phlets written under the name �Isaac  Bickerstaff.� Reluctantly setting  aside his loyalty to the Whigs, in  1710 he became the leading writer  for the Tories because of their support  for the established church. Journal to  Stella (written 1710-13) consists of  letters recording his reactions to the  changing world. As a reward for writ�  ing and editing Tory publications, in  1713 he was awarded the deanery of  St. Patrick�s Cathedral, Dublin. He  spent nearly all the rest of his life in  Ireland, where he devoted himself to  exposing English wrongheadedness  and their unfair treatment of the Irish.</p><p>His ironic tract �A Modest Proposal�</p><p>(1729) proposes ameliorating Irish  poverty by butchering children and selling them as food to wealthy English  landlords. His famously brilliant and bitter satire Gulliver�s Travels (1126),  ostensibly the story of its hero�s encounters with various races and societies  in remote regions, reflects Swift�s vision of humanity�s ambiguous position  between bestiality and rationality.</p><p>swimming In recreation and sports, the propulsion of the body through  water by combined arm and leg motions. Swimming is popular as an all-  around fitness routine and as a competitive sport. It has been included in  the modern Olympic Games since their inception in 1896.

Switzerland is divided into</p><p>three regions: the meadow-covered Jura  Mountains; the central Mittelland, a rich agricultural and urbanized area;  and the lofty crags of the Alps. It is one of the world�s major financial cen�  tres; its economy is based largely on international trade and banking, as  well as light and heavy industries. Manufactures include watches, preci�  sion instruments, machinery, and chemicals. Tourism and agriculture are  also important; products include grains, sugar beets, fruits and vegetables,  dairy products, chocolate, and wine. Despite diverse ethnic groups, reli�  gions, and languages, Switzerland has maintained the world�s oldest  democracy for some 700 years. It is a federal state with two legislative  houses; its head of state and government is the president of the federal  council. The original inhabitants were the Helvetians, who were conquered  by the Romans in the 1st century bc. Germanic tribes penetrated the region  from the 3rd to the 6th century ad, and Muslim and Magyar raiders ven�  tured in during the 10th century. It came under the rule of the Franks in the  9th century and the medieval empire (later the Holy Roman Empire) in the  11th century. In 1291 three cantons formed an anti-Habsburg league that  became the nucleus of the Swiss Confederation. It was a centre of the Ref�  ormation, which divided the confederation and led to a period of political  and religious conflict. The French organized Switzerland as the Helvetic  Republic in 1798. In 1815 the Congress of Vienna recognized Swiss inde�  pendence and guaranteed its neutrality. A new federal state was formed in  1848 with Bern as the capital. Switzerland remained neutral in both World  War I and World War II and has continued to defend this neutrality. It joined  the European Free Trade Association in 1960, but it has opted against joining  the European Union. It joined the United Nations in 2002.</p><p>Swope, Gerard (b.

Roman swords had a short, flat blade and a hilt distinct from the  blade. Medieval European swords were heavy and equipped with a large  hilt and a protective guard, or pommel. The blade was straight, double-  edged, and pointed. The introduction of firearms did not eliminate the  sword but led to new designs; the discarding of body armour required the  swordsman to be able to parry, and the rapier, a double-edged sword with  a narrow, pointed blade, came into use. Swords with curved blades were  used in India and Persia and were introduced into Europe by the Turks,  whose scimitar, with its curved, single-edged blade, was modified in the  West to the cavalry sabre. Japanese swords are renowned for their hardness  and extreme sharpness; they were the weapon of the samurai. Repeating  firearms ended the value of the sword as a military weapon, though its con�  tinued use in duels led to the modem sport of fencing.

It is dominated by Sydney Harbour Bridge, one of the biggest single�  span bridges in the world, and the Sydney Opera House. The city is widely  known for its water sports, recreational facilities, and cultural life. It is  the site of the Universities of Sydney (1850) and New South Wales (1949),  and Macquarie University (1964). Sydney was the host of the 2000 Sum�  mer Olympic Games.</p><p>Sydney Opera House Performing-arts centre on the harbour in Syd�  ney, Australia. Its dynamic, imaginative design by Danish architect Jpm  Utzon (b. 1918) won a competition in 1957 and brought Utzon interna�  tional fame. Construction posed a variety of problems, many resulting  from the bold design consisting of a series of glittering white shell-shaped  roofs. After several years of research, Utzon gave the vaults a more spheri�  cal geometry, making them easier and more economical to build. The  roofs are made up of precast concrete sections held together by cables.  The centre finally opened in 1973.</p><p>Sydow \'se-do,\ Swedish VsiE-dov\, Max von orig. Carl Adolf von  Sydow (b. April 10, 1929, Lund, Swed.) Swedish actor. After studying  at Stockholm�s Royal Dramatic Theatre School (1948-51), he became a  noted stage actor in Malmo and Stockholm. He is best known for his dour,  brooding characterizations in Ingmar Bergman�s films, notably The Sev�  enth Seal (1957), The Virgin Spring (1960), Winter Light (1963), Shame  (1968), and The Passion of Anna (1969). His numerous U.S. and inter�  national movies include The Greatest Story Ever Told (1965), The Exor�  cist (1973), Pelle the Conqueror { 1988), What Dreams May Come (1998),  and Minority Report (2002).</p><p>syllable Segment of speech usually consisting of a vowel with or with�  out accompanying consonant sounds (e.g., a, I, out, too, cap, snap,  check). A syllabic consonant, like the final n sound in button and widen,  also constitutes a syllable. Closed (checked) syllables end in a consonant,  open (free) syllables in a vowel. Syllables play an important role in the  study of speech and in phonetics and phonology.</p><p>syllogism Vsi-lo-ji-zomX Form of argument that, in its most commonly  discussed instances, has two categorical propositions as premises and one  categorical proposition as conclusion. An example of a syllogism is the  following argument: Every human is mortal (every M is P); every phi�  losopher is human (every S is M); therefore, every philosopher is mortal  (every S is P). Such arguments have exactly three terms (human, philoso�  pher, mortal). Here, the argument is composed of three categorical (as  opposed to hypothetical) propositions, it is therefore a categorical syllo�  gism. In a categorical syllogism, the term that occurs in both premises but  not in the conclusion (human) is the middle term; the predicate term in  the conclusion is called the major term, the subject the minor term. The  pattern in which the terms S, M, and P (minor, middle, major) are arranged  is called the figure of the syllogism. In this example, the syllogism is in  the first figure, since the major term appears as predicate in the first  premise and the minor term as subject of the second.</p><p>syllogistic \,si-b-'jis-tik\ Formal analysis of the syllogism. Developed in  its original form by Aristotle in his Prior Analytics c. 350 bc, syllogistic  represents the earliest branch of formal logic. Syllogistic comprises two  domains of investigation. Categorical syllogistic confines itself to cat�  egorical propositions and their variation with respect to modalities. Non-  categorical syllogistic is a form of logical inference using whole  propositions as its units, an approach traceable to the Stoics but only fully  developed by John Neville Keynes (1852-1949).</p><p>Sylvester II orig. Gerbert of Aurillac (b. c. 945, near Aurillac,  Auvergen, France�d. May 12, 1003, Rome) First French pope (999-  1003). Renowned as a scholar of logic and mathematics, he became arch�  bishop of Reims (991) and of Ravenna (c. 998). Appointed pope by his  former student, Otto III, Sylvester worked closely with Otto, strengthen�  ing papal authority in distant states such as Kiev and Norway as well as  in Italy. He denounced SIMONY, demanded clerical celibacy, and limited  the power of the bishops. He wrote textbooks on mathematics, the sci�  ences, and music and the philosophical work De rationali et de ratione  uti (�Concerning the Rational and the Use of Reason�). According to leg�  ends that emerged shortly after his death, his great learning was the result  of magical arts or the Devil�s coaching.</p><p>symbiosis Any of several living arrangements between members of two  different species, including commensalism, mutualism, and parasitism. The  species involved are called symbionts. In commensalism, one species (the  commensal) obtains nutrients, shelter, support, or locomotion from the</p><p>host species, which is substantially unaffected (e.g., remoras obtain loco�  motion and food from sharks). In mutualism, both species benefit. Many  mutualistic relationships are obligative; neither species can live without  the other (e.g., protozoans in the gut of termites digest the wood ingested  by the termites).</p><p>symbol Element of communication intended to represent or stand for a  person, object, group, process, or idea. Symbols may be presented graphi�  cally (e.g., the red cross and crescent for the worldwide humanitarian  agency) or representationally (e.g., a lion representing courage). They  may involve associated letters (e.g., C for the chemical element carbon),  or they may be assigned arbitrarily (e.g., the mathematical symbol �o for  infinity). Symbols are devices by which ideas are transmitted between  people sharing a common culture. Every society has evolved a symbol  system that reflects a specific cultural logic; and every symbolism func�  tions to communicate information between members of the culture in  much the same way as, but more subtly than, conventional language.  Symbols tend to appear in clusters and to depend on one another for their  accretion of meaning and value. See also semiotics.</p><p>symbolic interactionism See interactionism</p><p>Symbolism In art, a loosely organized movement that flourished in the  1880s and �90s and was closely related to the Symbolist movement in lit�  erature. In reaction against both Realism and Impressionism, Symbolist paint�  ers stressed art�s subjective, symbolic, and decorative functions and  turned to the mystical and occult in an attempt to evoke subjective states  of mind by visual means. Though aspects of Symbolism appear in the  work of Paul Gauguin, Vincent van Gogh, and the Nabis, its leading expo�  nents were Gustave Moreau, Odilon Redon, and Pierre Puvis de Chavannes.  Though associated primarily with France, it flourished all over Europe,  had great international impact, and influenced 20th-century art and lit�  erature.</p><p>Symbolist movement Literary movement that originated with a  group of French poets in the late 19th century, spread to painting and the  theatre, and influenced Russian, European, and American arts of the 20th  century. Reacting against the rigid conventions of traditional French  poetry, as seen in the precise description favoured by the Parnassian poets,  Symbolist poets sought to convey individual emotional experience  through the subtle, suggestive use of highly metaphorical language. The  arcane and indirect meaning of the symbol is evoked as a substitute for  the increasingly attenuated sense of collective and universal meanings.  Principal Symbolist poets included the Frenchmen Stephane Mallarme,  Paul Verlaine, and Arthur Rimbaud, and the Belgian poet Emile Verhaeren.  Many Symbolists were also identified with the Decadent movement. Just  as Symbolist painters avoided concrete representation in favour of fan�  tasy and imagination, Symbolist dramatists relied on myth, mood, and  atmosphere to reveal only indirectly the deeper truths of existence.</p><p>Symington Vsi-miq-tonV William (b. October 1763, Leadhills,  Lanarkshire, Scot.�d. March 22, 1831, London, Eng.) British engineer.  Educated for the ministry, he became a mechanic instead. He created a  working model of a steam-driven road carriage in 1786 and first used  steam for marine purposes the following year. In 1801-02 he developed  a successful steam-driven paddle wheel and used it to propel one of the  first practical steamboats, the Charlotte Dundas. Though his engine was  used successfully on the Forth and Clyde Canal in 1802, cautious man�  agers caused the project to be abandoned in 1803.</p><p>symmetry In geometry, the property by which the sides of a figure or  object reflect each other across a line (axis of symmetry) or surface; in  biology, the orderly repetition of parts of an animal or plant; in chemis�  try, a fundamental property of orderly arrangements of atoms in molecules  or crystals; in physics, a concept of balance illustrated by such funda�  mental laws as the third of Newton's laws of motion. Symmetry in nature  underlies one of the most fundamental concepts of beauty. It connotes  balance, order, and thus, to some, a type of divine principle.</p><p>Symonds Vsi-msndzX, John Addington (b. Oct. 5, 1840, Bristol,  Gloucestershire, Eng.�d. April 19, 1893, Rome) English essayist, poet,  and biographer. He traveled extensively for his health, finally settling in  Switzerland. His chief work, Renaissance in Italy (1875-86), is a series  of extended essays on cultural history. His writings include translations,  travel sketches, and studies of personalities such as Percy B. Shelley, Ben  Jonson, Sir Philip Sidney, Michelangelo, and Walt Whitman. His poetry  served primarily as a release from his difficult emotional life.

Feb. 28, 1865, Mil�  ford Haven, Pembrokeshire,</p><p>Eng.�d. Jan. 22, 1945, Wittersham,</p><p>Kent) English poet and critic. He  contributed to The Yellow Book, an  avant-garde journal, and edited The  Savoy (1896). His Symbolist Move�  ment in Literature (1899), the first  English work championing the  French Symbolist movement in poetry,  summed up a decade of interpreta�  tion and influenced William Butler  Yeats and T.S. Eliot. His poetry,  mainly disillusioned in feeling,  appears in such volumes as Silhou�  ettes (1892) and London Nights  (1895). He also translated the poetry  of Paul Verlaine and wrote travel pieces. After a nervous breakdown in  1908, he produced little apart from Confessions (1930), a moving account  of his illness.</p><p>symphonic poem or tone poem Musical work for orchestra  inspired by an extramusical story, idea, or �program,� to which the title  typically refers or alludes. It evolved from the concert overture, an over�  ture not attached to an opera or play yet suggestive of a literary or natu�  ral sequence of events. Franz Liszt, who coined the term, wrote 13 such  works. Famous symphonic poems include Bedrich Smetana�s The Moldau  (1879), Claude Debussy�s Prelude to the Afternoon of a Faun (1894), Paul  Dukas�s The Sorceror�s Apprentice (1897), Richard Strauss�s Don Quixote  (1897), and Jean Sibelius�s Finlandia (1900).</p><p>symphony Long musical composition for orchestra, usually in several  movements. The term (meaning �sounding together�) came to be the stan�  dard name for instrumental episodes, and especially overtures, in early  Italian opera. The late-17th-century Neapolitan opera overture, or sinfo-  nia, as established especially by Alessandro Scarlatti c. 1780, had three  movements, their tempos being fast-slow-fast. Soon such overtures began  to be performed by themselves in concert settings, like another forerun�  ner of the symphony, the concerto grosso. The two merged in the early  18th century in the symphonies of Giovanni Battista Sammartini (1700/  01-75). In c. 1750 German and Viennese composers began to add a minuet  movement. Joseph Haydn, the �father of the symphony,� wrote more than  100 symphonies of remarkable originality, intensity, and brilliance in the  years 1755-95; since Haydn, the symphony has been regarded as the most  important orchestral genre. Wolfgang Amadeus Mozart wrote about 35  original symphonies. Ludwig van Beethoven�s nine symphonies endowed  the genre with enormous weight and ambition. Later symphonists include  Franz Schubert, Felix Mendelssohn, Robert Schumann, Anton Bruckner,  Johannes Brahms, Antonin Dvorak, Pyotr Ilyich Tchaikovsky, and Gustav  Mahler; their 20th-century successors include Ralph Vaughan Williams,  Jean Sibelius, Dmitry Shostakovich, and Witold Lutoslawski.</p><p>symposium In ancient Greece, an aristocratic banquet at which men  met to discuss philosophical and political issues and recite poetry. It began  as a warrior feast. Rooms were designed specifically for the proceedings.  The participants, all male aristocrats, wore garlands and leaned on the left  elbow on couches, and there was much drinking of wine, served by slave  boys. Prayers opened and closed the meetings; sessions sometimes ended  with a procession in the streets. In Plato�s famous Symposium, an imagi�  nary dialogue takes place between Socrates, Aristophanes, Alcibiades, and  others on the subject of love. Aristotle, Xenophon, and Epicurus wrote  symposium literature on other subjects.</p><p>synagogue In Judaism, a community house of worship that also serves  as a place for assembly and study. Though their exact origins are uncer�  tain, synagogues flourished side by side with the ancient Temple cult; they  existed long before Jewish sacrifice and the established priesthood were  terminated with Titus�s destruction of the Second Temple (ad 70). There�  after, synagogues took on even greater importance as the unchallenged  focal point of Jewish life. There is no standard synagogue architecture. A</p><p>typical synagogue contains an ark (where the scrolls of the Law are kept),  an �eternal light� burning before the ark, two candelabra, pews, a bimah  (see bema), and sometimes a ritual bath ( mikvah ).</p><p>synapse \'si-,naps\ Site of transmission of electric nerve impulses  between two nerve cells or between a nerve cell and a gland or muscle  cell. At chemical synapses, impulses are transmitted across microscopic  spaces via chemical substances called neurotransmitters. In electric syn�  apses, direct communication between nerve cells whose membranes are  fused is possible because ions flow between the cells through channels.  Electric synapses are found mainly in invertebrates and lower vertebrates;  they transmit messages faster than chemical synapses. Chemical trans�  mission seems to have evolved in large, complex vertebrate nervous sys�  tems, in which multiple messages must be transmitted over long distances.</p><p>Synchromism Ysiq-kro-.mi-zonA Art movement concerned with the  purely abstract use of colour. Founded in Paris in 1912-13 by the U.S.  artists Stanton Macdonald-Wright and Morgan Russell, Synchromism  (�colours together�) was based on theories of colour with analogies to  musical patterns. It has much in common with the Orphism of Robert  Delaunay. The first Synchromist work, Russell�s Synchromy in Green  (1913), was exhibited at the Salon des Independants in 1913. Synchromism  briefly attracted several other U.S. artists, including Thomas Hart Benton.</p><p>synchronized swimming Swimming sport in which the movements  of one or more swimmers are synchronized with a musical accompani�  ment. The sport developed in the U.S. in the 1930s and was admitted as  an Olympic event (solo and duet only) in 1984; in 1996 the rules were  changed to allow only teams of eight women. Teams are judged on com�  pulsory and optional routines.</p><p>synchrotron Vsiq-kre-.tranV Cyclic particle accelerator in which the par�  ticle is confined to its orbit by a magnetic field. The strength of the mag�  netic field increases as the particle�s momentum increases. An alternating  electric field in synchrony with the orbital frequency of the particle pro�  duces acceleration. Synchrotrons are named according to the particles  they accelerate. The Tevatron, a proton synchrotron at the Fermi National  Accelerator Laboratory in Illinois, U.S., produces the highest particle  energies achieved so far.</p><p>synchrotron radiation Electromagnetic radiation emitted by charged  particles that are moving at speeds close to that of light when their paths  are altered. It is so called because it is produced by high-speed particles  in a synchrotron. Such radiation is highly polarized (see polarization) and  continuous. Its intensity and frequency depend on the strength of the mag�  netic field that alters the path of the particles, as well as on the energy of  those particles. Synchrotron radiation at radio frequencies is emitted by  high-energy electrons as they spiral through magnetic fields in space, such  as those around Jupiter. Synchrotron radiation is emitted by a variety of  astronomical objects, from planets to supernova remnants to quasars.</p><p>syncope Vsiq-k3-pe\ Effect of temporary impairment of blood circula�  tion to a part of the body. It is often used as a synonym for fainting, which  is loss of consciousness due to inadequate blood flow to the brain. Pale�  ness, nausea, sweating, and then pupil dilation, yawning, deep rapid  breathing, and rapid heartbeat usually precede it. It lasts from under a  minute to several minutes and may be followed by headache, confusion,  and a weak feeling. The cause may be physical (e.g., heart failure, low  blood sugar) or emotional (e.g., fear, anxiety). Abnormal vagus or auto�  nomic nerve response can cause fainting (without preceding symptoms)  triggered by ordinary activities such as urination, swallowing, coughing,  or standing up or by pressure on the pulse point in the neck. Local syn�  cope is coldness and numbness in a small area, especially the fingers, from  diminished blood flow.</p><p>syndicalism Vsin-di-ko-.li-zomN Movement advocating direct action by  the working class to abolish the capitalist order, including the state, and  to replace it with a social order based on the syndicat, a free association  of self-governing producers. Developed as a doctrine by leaders of the  French trade union movement at the end of the 19th century, syndicalism  was strongly influenced by the traditional anarchism and antiparliamen-  tarianism of the French working class. Syndicalists looked forward to  victory in a class war, after which society would be organized around the  syndicats. These bodies would coordinate their activities through a labour  exchange, which would function as an employment and economic plan�  ning agency. At the peak of its influence, before World War I, the move�  ment had in excess of one million members in Europe, Latin America,</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1858 I Synge &#x25BA; Syria</p><p>and the U.S. After the war, syndicalists tended to drift toward the Soviet  model of communism or to be lured by the ostensible benefits offered by  labour unions and democratic reforms.

After study�  ing languages and music in Dublin and France, he met William Butler Yeats,  who advised Synge to go to the west coast of Ireland to draw material  from life. From 1899 to 1902 he spent his summers on the Aran Islands,  observing the people and learning their language; he based his first plays,  In the Shadow of the Glen (1903) and Riders to the Sea (1904), on island�  ers� stories. His travels on the Irish west coast inspired his most famous  play. The Playboy of the Western World (1907); its unsentimental treat�  ment of Irish character traits caused riots at its opening at the Abbey The�  atre. His unfinished Deirdre of the Sorrows was performed in 1910. A  poetic dramatist of great power, he was a leading figure of the Irish liter�  ary RENAISSANCE.</p><p>synodic \so-'na-dik\ period Time required for a body in the solar sys�  tem to return to the same or about the same position relative to the Sun as  seen from Earth. The Moon�s synodic period is the time between succes�  sive recurrences of the same phase (e.g., the period between one full moon  and the next). A planet�s synodic period is the time required for Earth to  overtake it as both go around the Sun or (in the case of fast-moving Mer�  cury or Venus) for the other planet to overtake Earth. See also sidereal  PERIOD.</p><p>syntax Arrangement of words in sentences, clauses, and phrases, and  the study of the formation of sentences and the relationship of their com�  ponent parts. In English, the main device for showing this relationship is  word order; for example, �The boy loves his dog� follows standard  subject-verb-object word order, and switching the order of such a sen�  tence would change the meaning or make the sentence meaningless. Word  order is much more flexible in languages such as Latin, in which word  endings indicate the case of a noun or adjective; such inflections make it  unnecessary to rely on word order to indicate a word�s function in the  sentence.</p><p>synthesizer Machine that electronically generates and modifies sounds,  frequently with the use of a digital computer, for use in the composition of  electronic music and in live performance. The synthesizer generates wave  forms and then subjects them to alteration in intensity, duration, frequency,  and timbre. It may use subtractive synthesis (removing unwanted compo�  nents from a signal containing a fundamental and all related overtones),  additive synthesis (building tones from signals for pure sine-wave tones),  or other techniques, most importantly whole-sound sampling (digital  recording of sounds, usually from acoustic instruments). The first synthe�  sizer was developed c. 1955 by RCA. Compact, commercially viable syn�  thesizers, generally with pianolike keyboards, were produced in the 1960s  by Robert Moog (born 1934), Donald Buchla (born 1937), and others. With  transistor technology, these soon became portable and cheap enough for  practical performance use, and such instruments became fixtures in rock  bands, often displacing electric pianos and organs.

Without treatment, it may progress through three  stages: primary, characterized by a chancre and low fever; secondary  (weeks to months later; only half of those infected display symptoms),  with a skin and mucous-membrane rash, lymph node swelling, and bone,  joint, eye, and nervous system involvement; and tertiary. The tertiary stage  follows a latency period that can last years, and only one-fourth of those  infected display tertiary symptoms. These can be benign or incapacitat�  ing and even fatal; almost any part of the body may be attacked. Syphilis  can spread to a fetus from an infected mother. Other species of Treponema  cause similar but milder, nonsexually transmitted forms of syphilis (see  yaws). Several blood tests can detect syphilis, even during latency. Anti�  biotic treatment is effective.</p><p>Syr Darya \,sir-d3r-'ya\ ancient Jaxartes River River, Central Asia,  in Uzbekistan, Tajikistan, and Kazakhstan. Formed by the confluence of  two headstreams in the fertile Fergana Valley, it flows west-northwest for  1,374 mi (2,212 km) to empty into the Aral Sea. Its lower course is on  the eastern edge of the Kyzylkum desert. It is the longest river in Central  Asia but carries less water than does the Amu Darya. It is used extensively  for hydroelectric power and irrigation.</p><p>Syracuse Italian Siracusa ancient Syracusae Seaport city (pop.,  2001 prelim.: 121,000), eastern coast of Sicily, Italy. Founded in 734 bc  by Greeks from Corinth, it was seized by Hippocrates of Gela in 485 bc  and ruled by tyrants until a revolution established a democratic govern�  ment c. 465 bc. In 413 bc, during the Peloponnesian War, Syracuse  defeated an Athenian invasion force. Under the rule of Dionysius I the Elder  (405-367 bc), it became the most powerful of the Greek cities, fighting  three wars against rival Carthage. Syracuse fell to Rome in 211 bc. It was  sacked by Frankish invaders in ad 280 and captured by Arabs in 878; its  importance waned in medieval times. Now the commercial centre for an  agricultural district, it also supports the fishing and tourist industries. It  has many examples of medieval and Renaissance architecture as well as  Greek and Roman ruins. It is the birthplace of Theocritus and Archimedes.</p><p>Syracuse City (pop., 2001: 147,306), central New York, U.S. The site,  at the southern end of Lake Oneida, was once the territory of the Onon�  daga Indians and the headquarters of the Iroquois Confederacy. The area  was visited by the French in the 17th century. Indian hostility and the  swampy location precluded settlement until the establishment of a trad�  ing post in 1786. Soon a saltworks based on its brine springs began  operation; it supplied most of the nation�s salt until 1870. An important  port on the Erie Canal, Syracuse serves as a distribution centre for the  central New York agricultural region. It also manufactures pharmaceuti�  cals and electronics. It is the site of Syracuse University (1870) and the  Everson Museum of Art (founded 1896).</p><p>Syria officially Syrian Arab Republic Country, Middle East, along  the eastern coast of the Mediterranean Sea. Area: 71,498 sq mi (185,180  sq km). Population (2005 est.): 17,794,000. Capital: Damascus. Arabs are</p><p>the main ethnic group, and Kurds are the  largest minority. Languages: Arabic (offi�  cial), Kurdish, Armenian. Religions: Islam o , so , 10 0 mi</p><p>(predominantly Sunni); also Christianity, �--�- 160km</p><p>Druze. Currency: Syrian pound. Syria con�  sists of a coastal zone with abundant water supplies, a mountain zone that  includes the Anti-Lebanon Mountains, and a portion of the Syrian Desert.  The Euphrates River is its most important water source and only navigable  river. Syria has a mixed economy based on agriculture, trade, and min�  ing and manufacturing. Crops include cotton, cereals, fruits, tobacco, and  livestock. The main mineral resources are petroleum, natural gas, and iron  ore; manufactures include textiles, cement, and steel. Syria is a republic  with one legislative house; its head of state and government is the presi�  dent, who by law must be a Muslim. The legal system is based largely  on Islamic law. The area that now comprises Syria has been inhabited for  several thousand years.

In the 6th century bc it became part of the  Persian Achaemenian Empire, which fell to Alexander the Great in 330 bc.  Seleucid rulers governed it (301-c. 164 bc); then Parthians and Nabataean  Arabs divided the region. It flourished as a Roman province (64 bc-ad  300) and as part of the Byzantine Empire (300-634), until Arab Muslims  invaded and established control. Thereafter the region was ruled by vari�  ous Muslim dynasties. It came under the Ottoman Empire in 1516, which  held it, except for brief periods, until the British invaded in World War I  (1914-18). After the war it became a French mandate; it was fully inde�  pendent by 1946. It united with Egypt in the United Arab Republic (1958�  61). During the Six-Day War (1967), it lost the Golan Heights to Israel.  Syrian troops frequently clashed with Israeli forces in Lebanon during the  1980s and �90s. Hafiz al-Assad�s long regime (1971-2000) also was  marked by antagonism toward Syria�s neighbours Turkey and Iraq.</p><p>Syrian Desert Arid wasteland, Middle East.

If a solution exists, the system is con�  sistent; if not, it is inconsistent. A system of linear equations can be rep�  resented by a matrix whose elements are the coefficients of the equations.  Though simple systems of two equations in two unknowns can be solved  by substitution, larger systems are best handled with matrix techniques.</p><p>systems analysis In information processing, a phase of systems engi�  neering. The principal objective of the systems-analysis phase is the speci�  fication of what the system needs to do to meet the requirements of end  users. In the systems-design phase such specifications are converted to a  hierarchy of charts that define the data required and the processes to be  carried out on the data so that they can be expressed as instructions of a  computer program. Many information systems are implemented with  generic software, rather than with such custom-built programs.</p><p>systems ecology Branch of ecosystem ecology (the study of energy  budgets, biogeochemical cycles, and feeding and behavioral aspects of  ecological communities) that attempts to clarify the structure and func�  tion of ecosystems by means of applied mathematics, mathematical mod�  els, and computer programs. It concentrates on input and output analysis  and has stimulated the development of applied ecology: the application  of ecological principles to the management of natural resources, agricul�  tural production, and problems of environmental pollution.</p><p>systems engineering Technique of using knowledge from various  branches of engineering and science to introduce technological innova�  tions into the planning and development stages of a system. Systems  engineering was first applied to the organization of commercial telephone  systems in the 1920s and �30s. Many systems-engineering techniques  were developed during World War II in an effort to deploy military equip�  ment more efficiently. Postwar growth in the field was spurred by  advances in electronic systems and by the development of computers and  information theory. Systems engineering usually involves incorporating  new technology into complex, man-made systems, in which a change in  one part affects many others. One tool used by systems engineers is the  flowchart, which shows the system in graphic form, with geometric fig�  ures representing various subsystems and arrows representing their inter�  actions. Other tools include mathematical models, probability theory,  statistical analysis, and computer simulations.</p><p>systems programming Development of computer software that is  part of a computer operating system or other control program, especially  as used in computer networks. Systems programming covers data and  program management, including operating systems, control programs,  network software, and database management systems.</p><p>Szczecin \'shchet-,shen\ German Stettin \shte-'ten\ Seaport (pop.,  2000 est.: 416,500), near the mouth of the Oder River, northwestern</p><p>Poland. A Slavic fishing and commercial centre for centuries, it was  annexed to Poland by Mieszko I in the 10th century. Szczecin joined the  Hanseatic League in 1360. It passed to Sweden in 1648 and to Prussia in  1720 and remained under German control until it was transferred to  Poland after World War II. During the war the port was completely  destroyed and the city greatly depopulated. Under Polish administration  the port and city were rebuilt, and Szczecin is now part of Poland�s larg�  est port complex. It is a cultural hub of western Poland, and several insti�  tutions of higher education are located there.</p><p>Szechenyi Vsa-chen-yiV Istvan, Count (b. Sept. 21, 1791, Vienna,  Austrian Empire�d. April 8, 1860, Dobling, near Vienna) Hungarian  reformer and writer. Born to an aristocratic Hungarian family, he fought  against Napoleon and then traveled extensively in Europe. He returned to  Budapest to found the Hungarian National Academy of Sciences (1825)  and wrote several works that called for economic reforms and urged the  nobility to pay taxes to modernize Hungary. He led projects that improved  roads, made the Danube River navigable to the Black Sea, and built the  first suspension bridge at Budapest. In the 1840s he lost his following to  the more radical Lajos Kossuth. Entering the cabinet in 1848, Szechenyi  lost his sanity when conflict with Vienna erupted; he was removed to an  asylum near Vienna and later committed suicide.</p><p>Szechwan See Sichuan</p><p>Szell Vsel, 'zel\, George (b.

He made his debut as a pianist at age 11, and before his 20th  birthday he had appeared with the Berlin Philharmonic as pianist, con�  ductor, and composer. He established himself as an opera conductor in  various German cities, including Berlin (1924-30) and Prague (1930-36).  When World War II broke out, he settled in the U.S., conducting at the  Metropolitan Opera (1942-46) and then serving as musical director of the  Cleveland Orchestra (1946-70). There he imposed stern discipline but  won his players� devotion by his own fierce dedication. Under his direc�  tion the orchestra became known for its precision in playing and was con�  sidered one of the world�s finest.</p><p>Szent-Gyorgyi \sant-'jorj, sant-'jor-je\, Albert (b. Sept. 16, 1893,  Budapest, Hung., Austria-Hungary�d. Oct. 22, 1986, Woods Hole,  Mass., U.S.) Hungarian-born U.S. biochemist. His discoveries about the  roles played by certain organic compounds, especially vitamin C, in the  oxidation (see oxidation-reduction) of nutrients by cells brought him a  1937 Nobel Prize. He found and isolated an organic reducing agent from  plant juices and adrenal gland extracts and showed it was identical to  vitamin C. His work on intermediates in the cell laid the foundation for  the elucidation of the tricarboxylic acid cycle by Hans Adolf Krebs. In later  years he worked on the biochemistry of muscular action (demonstrating  the role of ATP) and of cell division.</p><p>Szilard \'zi-,lard\, Leo (b. Feb. 11, 1898, Budapest, Hung., Austria-  Hungary�d. May 30, 1964, La Jolla, Calif., U.S.) Hungarian-born U.S.  physicist. He taught at the University of Berlin (1922-33), then fled to  England (1934-37) and the U.S., where he worked at the University of  Chicago from 1942. In 1929 he established the relation between entropy  and transfer of information, and in 1934 he helped develop the first  method of separating isotopes of artificial radioactive elements. He helped  Enrico Fermi conduct the first sustained nuclear chain reaction and con�  struct the first nuclear reactor. In 1939 he was instrumental in establish�  ing the Manhattan Project, in which he helped develop the atomic bomb.  After the first use of the bomb, he promoted the peaceful uses of atomic  energy and the control of nuclear weapons, founding the Council for a  Livable World. In 1959 he received the Atoms for Peace Award.</p><p>Szymborska \shim-'b6r-sk3\, Wisfawa (b. July 2, 1923, Bnin, Pol.)  Polish poet. From 1953 to 1981 Szymborska was on the staff of the weekly  Zycie Literackie (�Literary Life�), gaining a reputation as a poet, book  reviewer, and translator of French poetry. Her first two volumes of poetry  were attempts to conform to Socialist Realism. Later poems, notable for  their precise and concrete language and ironic detachment, express her  dissatisfaction with communism and explore philosophical, moral, and  ethical issues. A selection of her poems was published in English trans�  lation as View with a Grain of Sand (1995). She received the Nobel Prize  for Literature in 1996.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1860 I T cell &#x25BA; Tabriz</p><p>T cell With the B cell, one of the two main types of white blood cell, essen�  tial parts of the immune system. T cells originate in the bone marrow,  mature in the thymus, and travel in the blood to other lymphoid tissues,  such as the spleen, tonsils, and lymph nodes. Through receptor molecules  on their surfaces, T cells directly attack invaders (antigens) by binding to  them and helping remove them from the body. Because the body contains  millions of T and B cells, many of which carry unique receptors, it can  respond to virtually any antigen. See also antibody, immunology.</p><p>T Tauri Vte-'t6r-I\ star Any of a class of very young stars with masses  less than about twice the Sun�s. Characterized by unpredictable changes  in brightness, they represent an early stage in stellar evolution, having  only recently been formed by the gravitational con�  densation of interstellar gas and dust. The energy by  which they shine derives from the gravitational col�  lapse itself. These young stars, though now contract�  ing more slowly, are still relatively unstable and will  remain so until their interior temperatures become  high enough to support nuclear fusion for energy gen�  eration. More than 500 T Tauri stars have been  observed.</p><p>T1 Type of broadband telecommunications connection (see broad�  band technology) used especially to connect Internet service providers  to the Internet�s infrastructure. Developed by Bell Labs in the 1960s,  the �T-carrier systems� offer entirely digital, full-duplex exchange  of data over traditional wire, coaxial cable, optical fibre, microwave  relay, or other communications media. The T1 lines carry about 1.5  megabits of data per second, while the related T3 lines carry  over 40. However, such systems are generally too expensive  for individual network users, who turn instead to ISDN lines,  cable modems, DSL connections, or some form of wireless or  satellite system for high-speed Internet access.</p><p>Ta hsueh See Da xue  T'a-li-mu Ho See Tarim River  Ta-lien See Dalian</p><p>Ta-wen-k'ou culture See Dawenkou culture  Ta Yu See Da Yu</p><p>Taaffe Vta-foV Eduard, count von (b.

A boyhood friend  of the future emperor Francis Joseph, he entered the civil service in 1852  and rose rapidly, serving as governor of upper Austria, minister of the  interior (1867, 1870-71, 1879), governor of Tirol (1871-79), and prime  minister. In his second term as premier, he forged a conservative coali�  tion that restored a degree of order among the Austrian Empire�s quar�  reling nationalities by granting concessions to the Polish and Czech  nationalists and bringing them into the Habsburg civil service.</p><p>Taal \ta-�al, 'tal. Lake formerly Lake Bombon Lake, southwestern  Luzon, Philippines. It covers an area of 94 sq mi (244 sq km) and occu�  pies a volcanic crater less than 10 ft (3 m) above sea level. Volcano Island  (984 ft or 300 m), which rises from the lake and is also called Taal Vol�  cano, contains another small crater (Yellow Lake).

After studying in Islamic  centres of learning in Iraq, Syria, and Egypt, he wrote the compendious  Commentary on the Qur'an (see TAFSlR), in which he annotated Islam�s holy  book with all of the juridical, lexicographical, and historical explanations  transmitted in the Hadith. His other major work was the History of Proph�  ets and Kings, which charted the history of human civilization from cre�  ation to the fall of the Umayyad dynasty.</p><p>Tabasco \t3-'bas-ko\ State (pop., 2000: 1,891,829), southeastern  Mexico. It covers an area of 9,756 sq mi (25,267 sq km), and its capital  is Villahermosa. Pre-Columbian Indian cultures included those of the  Quiche, Olmec, Tabasca, and Nahua peoples. The area was first visited by  Europeans in 1518; in 1519 Hernan Cortes clashed with the Indians, who  were partially subdued in the 1530s and �40s. Tabasco became a state in</p><p>Agriculture, forestry, beekeeping, commercial fishing, and cattle�  raising provided much of the state�s income before petroleum exploita�  tion began in the 1960s.

Elaborately  described in Exodus, it was divided into an outer room, the �holy place,�  and an inner room, the Holy of Holies, which housed the Ark of the Cov�  enant. With the erection of the Temple of Jerusalem, the Tabernacle no  longer served a purpose. In modern Roman Catholicism and Eastern Ortho�  doxy, the tabernacle is the receptacle on the church altar in which the con�  secrated elements of the Eucharist are stored.</p><p>tabla \'ta-bl3\ Pair of small drums, the principal per�  cussion in Hindustani music of northern India. The  higher-pitched daya, played with the right hand, is a  roughly cylindrical one-skinned drum, usually  wooden, normally tuned to the raga�s tonic. The  baya, played with the left hand, is a deep kettledrum  usually of copper; its pitch varies with pressure from the heel of the  player�s hand. A disk of black tuning paste on the membrane of each  drum gives it harmonic overtones.</p><p>table Article of furniture used in the Western world since at least  the 7th century bc, consisting of a flat slab of stone, metal, wood,  or glass supported by trestles, legs, or a pillar. Though tables were  used in ancient Egypt, Assyria, and Greece, only during the Middle  Ages, with the growing formality of life under feudalism, did tables  increasingly take on social significance. Tables with attached  legs appeared in the 15th century. The draw top was invented  in the 16th century, making it possible to double the table  length. Increasing contact with the East in the 18th century led to increas�  ing specialization in the design of occasional tables.</p><p>Table Bay Inlet, Atlantic Ocean, forming the harbour of Cape Town,  South Africa. It is 12 mi (19 km) long and 8 mi (12 km) wide. Although  less sheltered than other bays along the coast, it became a port of call for  ships traveling to India and the East because of the availability of fresh  water. The shore was permanently settled by the Dutch in 1652.</p><p>table tennis or (trademark) Ping-Pong Game similar to lawn ten�  nis that is played on a tabletop with wooden paddles and a small, hollow,  plastic ball. The object is to hit the ball so that it goes over the net and  bounces on the opponent�s half of the table in such a way as to defeat the  opponent�s attempt to reach and return it. Both singles and doubles games  are played. A match consists of the best of any odd number of games,  each game being won by the player or team who first reaches 11 points  or who, after 10 points each, gains a two-point lead. Invented in England  in the early 20th century, it soon spread throughout the world. Since the  mid-1950s, East Asian countries have dominated the sport. It has been an  Olympic sport for both men and women since 1988.</p><p>taboo Prohibition against touching, saying, or doing something for fear  of immediate harm from a supernatural force. The term is of Polynesian  origin and was first noted by Capt. James Cook during his 1771 visit to  Tonga, but taboos have been present in virtually all cultures. They may  include prohibitions on fishing or hunting at certain seasons, eating cer�  tain foods, interacting with members of other social classes, coming into  contact with corpses, and (for women) performing certain activities dur�  ing menstruation. Although some taboos can be traced to evident risks to  health and safety, there is no generally accepted explanation of most oth�  ers; most authorities agree that they tend to relate to objects and actions  that are significant for the maintenance of social order.</p><p>Tabriz \ta-'brez\ City (pop., 1996: 1,191,043), northwestern Iran. Earth�  quakes and invasions by Arabs, Turks, and Mongols have damaged the  city numerous times. The Turkic ruler Timur conquered it in 1392. During  the next 200 years control passed several times between Safavid Iran and  the Ottoman Empire. During the 18th�19th centuries it passed between  the Ottomans and the Russian Empire, and the same powers fought over  it in World War I (1914-18). In the 1850s a schismatic Shfite religious  leader known as the Bab (�Gateway�) and 40,000 of his followers were  executed there. It was damaged during the Iran-Iraq War (1980-90).  Notable ancient sites include the 15th-century Blue Mosque, renowned  for the splendour of its blue tile decoration, and the remains of the  12-sided tomb of Mongol leader MahmOd Ghazan.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Tabriz school &#x25BA; Taff Vale case I 1861</p><p>Tabriz school School of miniaturist painting founded by the Mongol  Il-Khans early in the 14th century. Reflecting the penetration of East Asian  traditions into Islamic painting, early Tabriz works were characterized by  light, feathery brush strokes, gentle colouring, and an attempt to create  the illusion of spatiality. The school reached its peak just as the Il-Khans  were being conquered by the Islamic Timurids (1370-1506). It continued  to be active in this period, though it was overshadowed by the workshops  in Shiraz and Herat.</p><p>Tachism Vta-.shi-zomN (from French, tache: �spot�) Style of painting  practiced in Paris after World War II and through the 1950s. Like its U.S.  equivalent, action painting, it featured the intuitive, spontaneous gesture of  the artist�s brush stroke. The Tachists, including Hans Hartung and  Georges Mathieu, produced large works of sweeping brush strokes and of  drips, blots, stains, and splashes of colour. Tachism was part of the postwar  movement known as Art Informel, inspired by U.S. Abstract Expressionism.</p><p>tachycardia \,ta-ki-'kar-de-3\ Heart rate over 100 (as high as 240) beats  per minute. When it is a normal response to exercise or stress, it is no  danger to healthy people, but when it originates elsewhere, it is an arrhyth�  mia. Symptoms include fatigue, faintness, shortness of breath, and feeling  the heart thumping. It may subside within minutes or hours with no last�  ing ill effects, but in serious heart, lung, or circulatory disease it can pre�  cede atrial fibrillation or heart attack and demands immediate medical  attention. Tachycardias can be treated by an electric shock to the heart,  by antiarrhythmic drugs, and by pacemakers.</p><p>tachyon \'ta-ke-,an\ Hypothetical subatomic particle whose velocity is  always greater than that of light. Its existence appears consistent with the  theory of relativity. Just as an ordinary particle such as an electron can  exist only at speeds less than that of light, a tachyon can exist only at  speeds greater than that of light. At such speeds, its mass would be real  and positive. On losing energy, a tachyon accelerates; the faster it trav�  els, the less energy it has. The existence of tachyons has not been estab�  lished experimentally.</p><p>Tacitus \'ta-s3-tos\ in full Publius Cornelius Tacitus (b. ad 56� d.</p><p>c. 120) Roman orator, public official, and historian. After studying rheto�  ric, he began his career with a minor magistracy, eventually advancing to  the proconsulate of Asia, the top provincial governorship (112-113). In  98 he wrote De vita Julii Agricolae, a biographical account of his father-  in-law, governor of Britain; and De origine et situ Germanorum (known  as the Germania ), describing the people of the Roman frontier on the  Rhine. His works on Roman history are the Histories , concerning the  empire from ad 69 to 96, and the later Annals, dealing with the empire  from ad 14 to 68; the latter effectively diagnoses the decline of Roman  political freedom he had described in the Histories. Only parts of each are  extant. Tacitus is regarded as perhaps the greatest historian and one of the  greatest prose stylists to write in Latin.</p><p>Tacoma City and seaport (pop., 2000: 193,556), western Washington,  U.S. Located on Puget Sound, Tacoma was settled in 1864 and grew to  become a lumbering and port city. Docks and wharves line its waterfront.  A boat-building centre, the city also has smelters, foundries, and electro�  chemical plants. It is a gateway to Mount Rainier National Park and is  connected by bridge to the Olympic Peninsula recreation areas. It is the  seat of the University of Puget Sound (1888) and Pacific Lutheran Uni�  versity (1890).</p><p>Taconic Orogeny Uo-'ka-nik-o-'ra-jo-neV Mountain-building event  that affected the Appalachian Geosyncline along the eastern coast of the  U.S. Evidence for the orogeny is most pronounced in the northern Appa�  lachian Mountains, but its effects can be noted as far away as Tennessee  and Georgia. Events ascribed to it include the development of New York�s  Taconic Range and Vermont�s Green Mountains. Originally thought to  have occurred at approximately the Ordovician-Silurian boundary (c. 443  million years ago), it is now generally considered to have consisted of  several pulses from the mid-Ordovician to the early Silurian Period.</p><p>Taconic Range Part of the Appalachian mountain system, northeastern  U.S. The range extends 150 mi (240 km) from southern Vermont to north�  ern New York. Mount Equinox (3,816 ft [1,163 m]) in southwestern Ver�  mont is the highest peak. In Massachusetts the mountains form the  western section of the Berkshire Hills.

It is concerned  with the approach to combat, placement of troops, use made of weapons,  vehicles, ships, or aircraft, and execution of movements for attack or  defense. In general, tactics deal with the problems encountered in actual  fighting. Tactical thinking attempts to coordinate personnel with the exist�  ing weapons technology and apply both to the terrain and enemy forces  in a way that uses the fighting force to best advantage. Deployment  involves placing each type of weapon where it can do the most damage  to the enemy or provide the most protection to one�s own forces. Timing  and direction of attack are also important considerations. At sea, direc�  tion was especially crucial in the era of wind-powered warships. In recent  wars, timing has been a crucial factor in mounting airborne strikes that  take advantage of the element of surprise.

Taft later taught  law at Yale University (1913-21), served on the National War Labor  Board (1918), and was a supporter of the League of Nations. As chief  justice of the U.S. Supreme Court (1921-30), he introduced reforms that  made the court more efficient. His important opinion in Myers v. U.S.  (1926) upheld the president�s authority to remove federal officials.</p><p>Taft-Hartley Act officially Labor-Management Relations Act</p><p>(1947) U.S. legislation that restricted labour unions. Sponsored by Sen.  Robert A. Taft and Rep. Fred A. Hartley, Jr., the act amended much of the  pro-union Wagner Act (1935) and was passed by a Republican-controlled  Congress over the veto of Pres. Harry S. Truman. It allowed employees  the right not to join unions (outlawing the CLOSED shop) and required</p><p>advance notice of a labour strike, authorized an 80-day federal injunction  when a strike threatened national health or safety, narrowed the definition  of unfair labour practices, specified unfair union practices, restricted union  political contributions, and required union officials to take an oath pledg�  ing they were not communists.

As the language of Manila,  the capital and chief city of the Philippines, Tagalog has long had an  importance outside its own speech area. With vocabulary enrichment from  other Philippine languages, it has been made the basis of Pilipino, the  national language; widely used in education and the media, Pilipino is  now understood by more than 60% of the Philippine population. Though  a script ultimately of South Asian origin was in use for Tagalog in the  16th century (see Indic writing systems), all recent literature in the language  has utilized adaptations of the Latin alphabet.</p><p>Taglioni \tal-'yo-ne\, Marie (b. April 23, 1804, Stockholm, Swed.�d.  April 24, 1884, Marseille, Fr.) Italian ballet dancer. She trained with her  dancer-choreographer father, Filippo Taglioni (1777-1871), and made her  debut in Vienna in 1822. In her father�s ballet La Sylphide , introduced at  the Paris Opera in 1832, she became one of the first to dance on pointe.  She created a delicate new style, marked by floating leaps and balanced  poses such as the arabesque, that typified the early 19th-century Roman�  tic style. Her diaphanous white skirts would evolve into the tutu worn by  most classical ballerinas. She toured throughout Europe and, after leav�  ing the Opera in 1837, danced with the Imperial Ballet in St. Petersburg;  she retired from dancing in 1847.</p><p>Tagore Vta-,g6r,\ English \ta-'g6r\ / Debendranath (b. May 15,  1817, Calcutta, India�d. Jan. 19, 1905, Calcutta) Hindu philosopher and  religious reformer. Born into a wealthy landowning family, he was edu�  cated in both Eastern and Western philosophy. Striving to purge Hindu�  ism of abuses, he spoke vehemently against suttee and tried to bring  education within the reach of all. He was active in the Brahmo Samaj. In  his zeal to erase idolatry and undemocratic practices, he rejected the Vedas  as deficient in dictating guidelines for human behaviour. Failing to find a  middle path between radical rationalism and Brahman conservatism, he  retired from public life. He was known as the Great Sage. Rabindranath  Tagore was his son.</p><p>Tagore, Rabindranath (b. May 7, 1861, Calcutta, India�d. Aug. 7,  1941, Calcutta) Bengali poet, writer,  composer, and painter. The son of  Debendranath Tagore, he published  several books of poetry, including  Manasi, in his 20s. His later religious  poetry was introduced to the West in  Gitanjali (1912). Through interna�  tional travel and lecturing, he intro�  duced aspects of Indian culture to the  West and vice versa. He spoke  ardently in favour of Indian indepen�  dence; as a protest against the Mas�  sacre of Amritsar, he repudiated the  knighthood he had received in 1915.</p><p>He founded an experimental school  in Bengal where he sought to blend  Eastern and Western philosophies; it  became Vishva-Bharati University  (1921).

Though  blinded by an illness at age two, he became a professor of Arabic litera�  ture at the secular University of Cairo, where his bold views often enraged  Islamic religious conservatives. An outstanding figure of the modernist  movement in Egyptian literature, he wrote novels, stories, criticism, and  social and political essays. Outside Egypt he is best known for his auto�  biography, the two-part Al-Ayyam, published in English as An Egyptian  Childhood (1932) and The Stream of Days (1943), which was the first  modern Arab literary work to be acclaimed in the West.</p><p>Tahiti Island, Society Islands, French Polynesia, central South Pacific  Ocean. The largest of the Society Islands, it occupies an area of 402 sq  mi (1,042 sq km) in their eastern group. Papeete, the capital of French  Polynesia, is on Tahiti. The island�s interior is mountainous, rising to  7,339 ft (2,237 m) at Mount Orohena; its towns are located on the coastal  plain. Long inhabited by Polynesians, it was visited by British Capt. Sam�  uel Wallis in 1767 and in 1768 by Louis-Antoine de Bougainville, who  claimed it for France. The first permanent European settlers were English  missionaries who arrived in 1797. It became a French colony in 1880 and  is now part of the self-governing overseas territory of French Polynesia.  Continued French nuclear testing in the area has angered the inhabitants  and brought calls for independence.

Dating to the  3rd century ad, Tai Chi Chuan consists of two major schools, the Wu and  the Yang. Depending on the school, the number of exercises varies from  24 to more than 100.</p><p>T'ai-chung \ , ti-'chuq\ City (pop., 2002 est.: 990,041), west-central Tai�  wan. Most of the old town was tom down under the Japanese occupation  (1895-1945) and replaced by a planned modern city. An agricultural cen�  tre since the early 19th century, it is a major market for the rice, sugar,  and bananas produced in the surrounding area. In the 1970s an interna�  tional seaport was developed west of the city, and T�ai-chung was des�  ignated an export-processing zone to encourage foreign investment. It is  also a cultural centre, with various institutions of higher education. In  1999 it suffered one of Taiwan�s worst earthquakes.</p><p>T'ai Hsu See Tai Xu</p><p>Tai languages Family of closely related languages spoken in South�  east Asia and southern China by more than 80 million people. According  to a widely used classification, Tai comprises three branches. The South�  western group includes Thai, the national language of Thailand; north�  eastern Thai and Lao, spoken in eastern Thailand and Laos; Pak Tay  (South Thai), spoken in southern Thailand; Shan, spoken in eastern and  northern Myanmar; and Tai Dam (Black Tai) and Tai Don (Tai Khaw, or  White Tai), spoken mainly in North Vietnam. The Central group includes  Nung and South Zhuang, a dialect chain in northern Vietnam and China�s  Guangxi province; and Tay (Tho), spoken in the same area. The North�  ern group includes Buyi and North Zhuang, a dialect chain spoken in  Guangxi, Guizhou, and Yunnan, China. All Tai languages are tone lan�  guages. Most scholars believe the Tai family is related to a number of  other languages spoken by minority peoples of southern China and north�  ern Vietnam. Together with Tai, the entire group has been named the Kadai  or Tai-Kadai family.</p><p>T'ai-nan Vtl-�nan \ formerly Dainan City (pop., 2002 est.: 742,574),  southwestern Taiwan. It is one of the oldest urban settlements on the  island. The Han Chinese settled there as early as 1590. The Dutch arrived  in the city in 1623 and stayed until they were driven out in 1662 by Zheng  Chenggong, who made it his capital. It remained the island�s capital when  the Qing dynasty reestablished Chinese control over Taiwan (1683). Under  Chinese rule in the 19th century, it grew into a prosperous city and was  the commercial and educational centre of Taiwan. After the transfer of the  capital to Taipei in 1891, it became primarily commercial. It expanded dur�  ing the Japanese occupation (1895-1945).

In 1921 he began publication of the influential journal Hai-  chaoyin (�The Voice of the Sea Tide�). Heavily influenced by Sun Yat-  sen and the revolution of 1911, he sought to reform the education of monks  and promoted social welfare activities.

Birds� tail feathers aid in flight maneuverability.

Teaching at the Ecole des Beaux-Arts in Paris (1864-83),  he earned a reputation as one of the most esteemed exponents of 19th-  century French positivism with his attempts to apply the scientific method to  the study of the humanities. His works include a History of English Lit�  erature (1863-64), containing an explanation of his approach to cultural  and literary history and his scientific attitude toward criticism; On Intelli�  gence (1871), a study in psychology; and his monumental historical analy�  sis Les Origines de la France contemporaine, 3 vol.

Founded in the early 18th century, it became an important centre  of overseas trade in the mid-19th century. When Taiwan was proclaimed  a province of China in 1886, Taipei was later made the capital, and it  retained that designation under Japanese rule (1895-1945). In 1949 it  became the administrative centre of the Chinese Nationalist government.  It was designated a special municipality in 1967. Taipei is the commer�  cial, financial, industrial, and transportation centre of Taiwan. Its many  educational institutions include the National Taiwan University (1928).  The city�s National Palace Museum houses one of the world�s largest col�  lections of Chinese artifacts. The Taipei 101 building became the world�s  tallest building upon completion of its framework in 2003.</p><p>Taiping Vtl-'piqX Rebellion (1850-64) Large-scale rebellion against  the Qing dynasty in China. The peasants, having suffered floods and fam�  ines in the late 1840s, were ripe for rebellion, which came under the lead�  ership of Hong Xiuquan. Hong�s visions convinced him he was the  younger brother of Jesus, and he saw it as his duty to free China from  Manchu rule. He preached the brotherhood and sisterhood of all people  under God; property was to be held in common. His followers� militant  faith unified a fiercely disciplined army that swelled to more than a mil�  lion men and women (women were treated as equals by Taiping rebels).  They captured Nanjing in 1853 and renamed it Tianjing (�Heavenly Capi�  tal�). Their attempts to capture Beijing failed, but an expedition into the  upper Yangtze River (Chang Jiang) valley scored many victories. Hong�s  idiosyncratic Christianity alienated both Western missionaries and the  Chinese scholar-gentry. Without the gentry, the Taiping forces were  unable to govern the countryside or supply their cities effectively. The  leadership strayed from its original austerity and descended into power  struggles that left Hong without competent help. In 1860 an attempt to  take Shanghai was repelled by U.S.- and British-led forces, and by 1862  Chinese forces under Zeng Guofan had surrounded Nanjing. The city fell  in 1864, but almost 100,000 of the Taiping followers preferred death to  capture. Sporadic resistance continued elsewhere until 1868. The rebel�</p><p>lion ravaged 17 provinces, took some 20 million lives, and left the Qing  government unable to regain an effective hold over the country.

March 21,  1181, Kyoto) Leader of the powerful Taira family and the first member  of the warrior class (samurai) to rule Japan. The Taira family had made  itself useful to the imperial court quelling pirates on Japan�s Inland Sea.  In 1156, when the retired emperor Sutoku (see insei) enlisted the aid of  the Minamoto warrior family to help in a rebellion against the reigning  emperor Go-Shirakawa, Kiyomori supported Go-Shirakawa and defeated  the Minamoto. The Minamoto staged a comeback in 1159-60, but Kiy�  omori defeated them again, executing all the Minamoto males except the  children Minamoto Yoritomo and Minamoto Yoshitsune, who would later  overthrow him. Temporarily victorious, Kiyomori received the highest  court rank and manipulated the throne by marrying his daughters into the  imperial family. The Taira forces took on the effete ways of the aristocrats  and were no match for the frontier-hardy Minamoto, who defeated them  in 1185. See also Gempei War; Kamakura period.</p><p>Taisho period (1912-26) Period in Japanese history corresponding to  the reign of the Taisho emperor, Yoshihito (1879-1926). It followed the  Meiji period and represented a continuation of Japan�s rise on the interna�  tional scene and liberalism at home. Politically, the country moved toward  broader representational government. The tax qualification for voting was  reduced, enfranchising more voters, and was eliminated in 1925. Party  politics flourished, and legislation favourable to labour was passed. Japan  continued to push China for economic and political concessions and  entered into treaties with Western nations that acknowledged its interests  in Korea, Manchuria, and the rest of China. Rural Japan did not fare as  well as urban Japan, and an economic depression at the end of the Taisho  period caused much suffering. See also Showa period.</p><p>Tait, Archibald C(ampbell) (b.

In 1836 he became a deacon and for five years he was also a  curate at two villages near Oxford. In 1842 he succeeded Thomas Arnold  as headmaster of Rugby School, and in 1849 he became dean of Carlisle  Cathedral. He became bishop of London in 1856; in that position he  stressed reconciliation between evangelical churchmen and those who  supported the Oxford movement. As archbishop of Canterbury (from  1868), he oversaw the disestablishment of the Anglican Church of Ireland  and the passage of the Burials Act (1880), which allowed non-Anglican  burial services in Anglican churchyards.</p><p>Taiwan formerly Formosa Island, western Pacific Ocean, off south�  eastern China, and since 1949 the principal component of the Republic  of China (which also includes Matsu and Quemoy islands and the Pesca�  dores). Area: 13,972 sq mi (36,188 sq km), including its outlying islands.  Population (2005 est.): 22,725,947. Administrative centre: Taipei. Han Chi�  nese constitute virtually the entire population. Languages: Mandarin Chi�  nese (official); Taiwanese, Fukien, and Hakka dialects also spoken.  Religions: Buddhism, Daoism, Confucianism, Christianity. Currency:  new Taiwan dollar. Lying 100 mi (160 km) off the Chinese mainland, Tai�  wan is composed mainly of mountains and hills, with densely populated  coastal plains in the west. It has one of the highest population densities  in the world and is a leading industrial power of the Pacific Rim, with an  economy based on manufacturing industries, international trade, and ser�  vices. Leading exports include nonelectrical and electrical machinery,  electronics, textile products, plastic articles, and transportation equipment.  Taiwan is a major producer of Chinese-language motion pictures. It is a  republic with one legislative branch; its chief of state is the president, and  the head of government is the premier. Known to the Chinese as early as  the 7th century, the island of Taiwan was widely settled by them early in  the 17th century. In 1646 the Dutch seized control of the island, only to  be ousted in 1661 by a large influx of Chinese refugees, supporters of the  Ming dynasty. Taiwan fell to the Manchu in 1683 and was not open to  Europeans again until 1858. In 1895 it was ceded to Japan following the  first Sino-Japanese War. A Japanese military centre in World War II, it was  frequently bombed by U.S. planes. After Japan�s defeat it was returned  to China, which was then governed by the Nationalists. When the com�  munists took over mainland China in 1949, the Nationalist Party govern�  ment fled to Taiwan and made it their seat of government, with Gen.  Chiang Kai-shek as president.

There he built up a regional admin�  istration and an entourage of talented officials. His brothers are said to  have plotted to kill him; he did away with them instead, and his father  soon abdicated in his favour. He restored normal civil administration to  local government and created a unified civil service. He further devel�  oped the state schools created by his father and launched the editing of  the Confucian Classics.

An upright man, Taizu forgave minor faults while holding his offi�  cials accountable in important matters. He had his ministers submit rough  drafts of papers for his review, and he frequently traveled about incog�  nito to observe conditions among his people. He reformed the Chinese  examination system to prevent favouritism and began to award larger num�  bers of degrees. He gradually moved the administration of the prefectures  from the military to civil officials. At his death, a solid foundation had  been laid for the future development of the dynasty.</p><p>Taj Mahal Vtazh-mo-'halX Mausoleum complex on the southern bank of  the Yamuna River, outside Agra, India. It was built by the Mughal emperor  Shah Jahan in memory of his wife, Mumtaz Mahal, who died in 1631.  The Taj complex, begun c. 1632, took 22 years to complete. At its centre  lies a square garden area bounded by two smaller, oblong sections, one  comprising the mausoleum and the other an entrance gateway. The mau�  soleum, of pure-white marble inlaid with semiprecious stones, is flanked  by two red sandstone buildings, a mosque on one side and an identical  building for aesthetic balance on the other. It stands on a high marble  plinth with a minaret at each corner. It has four identical facades, each  with a massive central arch 108 ft (33 m) high, and is surmounted by a  bulbous double dome and four domed kiosks. Its interior, with fine,  restrained stone decoration, centres on an octagonal chamber containing  the marble tombs, enclosed by a perforated marble screen, with sar�  cophagi below. Regarded as one of the world�s most beautiful buildings,  it was designated a UNESCO World Heritage site in 1983. Steps have been  taken since the late 1990s to reduce air pollution that has damaged the  facade of the building.</p><p>Tajikistan \ta-ji-ki-'stan\ officially Republic of Tajikistan Country,  Central Asia. Area: 55,300 sq mi (143,100 sq km). Population (2005 est.):  6,849,000. Capital: Dushanbe. The majority of the population are Tajiks;</p><p>Uzbeks make up a large minority. Lan�  guage: Tajik (official). Religion: Islam  (predominantly Sunni). Currency: somoni.  Tajikistan is a mountainous country; about  half of its territory lies at elevations above  10,000 ft (3,000 m), with the Pamirs dominating the east. The entire region  is prone to seismic activity. The Amu Darya and Syr Darya rivers cross it and  are used for irrigation. Cotton, cattle, fruits, vegetables, and grains are  raised. Heavy industries include coal mining, petroleum and natural gas  extraction, metalworking, and nitrogen fertilizer production. Notable light  industries are cotton milling, food processing, and textiles. Tajikistan is a  republic with two legislative houses; the chief of state is the president, and  the head of government is the prime minister. Settled by Persians c. the 6th  century bc, Tajikistan was part of the empires of the Persian Achaemenian</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1866 I Tajumulco Volcano &#x25BA; Tallapoosa River</p><p>dynasty and of Alexander the Great and his successors. In the 7th-8th cen�  tury ad it was conquered by the Arabs, who introduced Islam. The Uzbeks  controlled the region in the 15th�18th centuries. In the 1860s the Russian  Empire took over much of Tajikistan. In 1924 it became an autonomous  republic under the administration of the Uzbek S.S.R., and it gained union  republic status in 1929. It achieved independence with the collapse of the  Soviet Union in 1991. Civil war raged through much of the 1990s between  government forces and an opposition composed mostly of Islamic mili�  tants. A peace agreement was reached in 1997.</p><p>Tajumulco \,ta-hu-'mul-ko\ Volcano Volcanic mountain, western  Guatemala.

It is thought to sit atop the remains of an older volcano.</p><p>Takebe Katahiro (b. 1664, Edo, Japan�d. Aug. 24, 1739, Edo) Japa�  nese mathematician of the wasan (�Japanese calculation�) tradition who  extended and disseminated the mathematical research of his teacher Seki  Takakazu. He served successively two shoguns, Tokugawa Ienobu and  Tokugawa Yoshimune (see Tokugawa period). Takebe became a pupil of  Seki at the age of 13 and, together with his brother Kataaki, remained  with him until his death in 1708. The brothers were the main craftsmen  of Seki�s project (launched 1683) to record mathematical knowledge in  an encyclopaedia. The Taisei sankei (�Comprehensive Classic of Math�  ematics�), in 20 volumes, was finally completed by Takebe Kataaki in  1710. It gives a good picture of Seki�s skill at reformulating problems,  as well as Takebe Katahiro�s ability to correct, perfect, and extend his  master�s intuitions.</p><p>Takemitsu \ta-ke-'mit-su\, Toru (b. Oct. 8, 1930, Tokyo, Japan�d.  Feb. 20, 1996, Tokyo) Japanese composer. In 1951 he founded Tokyo�s  Experimental Laboratory to promote an integration of Japanese music  with contemporary European developments. Soon acknowledged as  Japan�s leading composer, he explored avant-garde techniques such as  serialism, aleatory music, graphic notation, and electronic music, combin�  ing them with traditional Japanese motives and instruments (e.g., Novem�  ber Steps , 1967, for biwa, shakuhachi , and orchestra). He created an  individual sound world in which silence itself is an important element.</p><p>Takfir wa al-Hijrah Uak-'fer-wal-'hij-r S\ Arabic "Excommunica�  tion and [Holy] Flight" Name given by Egyptian authorities to a  radical Islamic group calling itself the Society of Muslims. It was founded  in 1971 by a young agronomist, ShukrI Mustafa, who had been arrested  in 1965 for distributing Muslim Brotherhood leaflets and was released from  prison in 1971. Appealing to those who saw mainstream society�from  which the group sought to flee (see Hijrah) �as weak, corrupt, and  un-Islamic, it engaged in acts of terrorism and was initially thought to be  behind the assassination of Anwar el-Sadat. The group soon dissolved,  partly because of the extreme rigour of its doctrine, and is noteworthy  because its actions initiated the repression of fundamentalist groups by  security services in Egypt in the late 1970s.</p><p>Takla Makan \,ta-klo-m3-'kan\ Desert Chinese Taklimakan  Shamo or T'a-k'o-la-ma-kan Sha-mo Desert, forming the  greater part of the Tarim Basin, west-central China. One of the world�s  largest sandy wastes, it is about 600 mi (965 km) across, with an area of  105,000 sq mi (272,000 sq km). It is flanked by high mountain ranges,  including the Kunlun Mountains, whose rivers penetrate the desert 60-120  mi (100-200 km) before drying up in its sands. Its wind-blown sand cover  is as much as 1,000 ft (300 m) thick and has formed such features as  pyramidal dunes that can reach heights of 1,000 ft (300 m).</p><p>Taksin Ytak-sin\ or Phraya Taksin (b. April 17, 1734, Ayutthaya�d.  April 6, 1782, Thon Buri) Thai general and later king (1767-82) who  reunited Siam (Thailand) after its defeat by Myanmar (Burma). While  Taksin was a provincial governor, his troops were among those besieged  by the forces of Myanmar in 1766-67, but he escaped and raised new  troops. He drove out the invaders and defeated other contenders for the  throne, then extended his power into neighbouring states. A better con�  queror than ruler, he was deposed and probably executed in 1782.</p><p>Talbot, William Henry Fox (b. Feb. 11, 1800, Melbury Abbas, Dor�  set, Eng.�d. Sept. 17, 1877, Lacock Abbey, near Chippenham, Wiltshire)  English chemist and pioneer photographer. In 1840 he developed the cal-  otype, an early photographic process that improved on the daguerreotype;  it involved the use of a photographic negative from which multiple prints  could be made. In 1835 he published his first article documenting a pho�</p><p>tographic discovery, that of the paper negative. His The Pencil of Nature  (1844-46) was the first book with photographic illustrations. Talbot also  published many articles on mathematics, astronomy, and physics.</p><p>talc Common silicate mineral that is distinguished from almost all other  minerals by its extreme softness. Its soapy or greasy feel accounts for the  name soapstone, given to compact aggregates of talc with other rock�  forming minerals. Soapstones have been used since ancient times for  carvings, ornaments, and utensils. Resistant to most reagents and to mod�  erate heat, they are especially suitable for sinks and countertops. Talc is  also used in lubricants, leather dressings, toilet and dusting powders, and  certain marking pencils; as a filler in ceramics, paint, paper, roofing mate�  rials, plastic, and rubber; as a carrier in insecticides; and as a mild abra�  sive in the polishing of cereal grains.</p><p>Talcahuano \,tal-ka-'wa-no\ City (pop., 2002 est.: 245,000), south-  central Chile.

It is also an important commercial, fishing, and manufac�  turing centre. The Peruvian ironclad Hudscar , captured by Chile during  the War of the Pacific (1879), is moored in the harbour.</p><p>Taliban \,ta-le-'ban\ Political and religious faction and militia that came  to power in Afghanistan in the mid-1990s. Following the Soviet Union�s  1989 withdrawal from Afghanistan (see Afghan Wars), the Taliban (Per�  sian: �Students�)�whose name refers to the Islamic religious students  who formed the group�s main recruits�arose as a popular reaction to the  chaos that gripped the country. In 1994-95, under the leadership of Mul�  lah Mohammad Omar, the Taliban extended its control in Afghanistan  from a single city to more than half the country, and in 1996 it captured  Kabul and instituted a strict Islamic regime. By 1999, the Taliban con�  trolled most of Afghanistan but failed to win international recognition of  its regime because of its harsh social policies�which included the almost  complete removal of women from public life�and its role as a haven for  Islamic extremists. Among these extremists was Osama bin Laden, the  expatriate Saudi Arabian leader of Al-Qaeda, a network of Islamic mili�  tants that had engaged in numerous acts of terrorism. The Taliban�s refusal  to extradite bin Laden to the U.S. following the September 1 1 attacks in  2001 prompted the U.S. to attack Taliban and Al-Qaeda forces in Afghani�  stan, driving the former from power and sending the leaders of both  groups into hiding.

Elected to repre�  sent the clergy at the Estates-General  (1789), he became the �bishop of the Revolution� by calling for confis�  cation of church property to fund the new government and supporting the  Civil Constitution of the Clergy. Excommunicated by the pope in 1790, he  was sent to England as an envoy in 1792. He was expelled from France  during the Reign of Terror, lived in the U.S. (1794-96), then returned to  serve in the Directory as foreign minister (1797-99). He was forced to  resign briefly for involvement in bribery scandals, including the XYZ  Affair. Adept at political survival, he supported Napoleon and again  became foreign minister (1799-1807) and later grand chamberlain (1804-  07). He resigned in opposition to Napoleon�s policy toward Russia but  continued to advise him, arranging his marriage with Marie-Louise of Aus�  tria. As Napoleon faced defeat, Talleyrand secretly worked to restore the  monarchy; in 1814 he was appointed foreign minister to Louis XVIII and  represented France at the Congress of Vienna. Forced by ultraroyalists to  resign (1815), he later became involved in the July Revolution of 1830 and  served as ambassador to Britain (1830-34).</p><p>Tallinn Yta-lon \formerly (until 1918) Revel Vra-vol\ Seaport city (pop.,  2001: 399,850), capital of Estonia. It is located on the Gulf of Finland. A  fortified settlement existed there from the late 1st millennium bc and a  town in the 12th century ad. In 1219 it was captured by the Danes, who  built a new fortress. Trade flourished after it joined the Hanseatic League  in 1285. In 1346 it was sold to the Teutonic Order, and in 1561 it passed  to Sweden. Russia captured it in 1710, and it remained a Russian city  until 1918, when it became the capital of independent Estonia. From 1940  to 1991 Estonia was a republic of the U.S.S.R. During World War II the  city was occupied by German forces and was severely damaged. Rebuilt,  it again became the capital of independent Estonia in 1991.

An organist at abbeys and churches from  1532, by 1543 he was a gentleman of the Chapel Royal, as both organist  and composer. Though a Catholic, he was one of the first to write hymns in  English for the Anglican church. During Mary I�s Catholic reign, he wrote  Latin masses, but he remained in favour after Elizabeth I�s accession. His  powerful Lamentations of Jeremiah are regarded as his greatest body of  work; his 40-part motet Spem in alium is his most famous piece. He also  wrote three masses and about 40 other motets.

Influenced by the painter</p><p>Jacques- Louis David, he became an early advocate of historical costuming,  and he created a sensation by appearing onstage in a Roman toga. After  political dissension split the company (1789), the pro-republican Talma  established a rival troupe. He developed realism in his staging and insisted  on a naturalistic rather than a declamatory acting style. In 1799 his troupe  was reunited with the Comedie-Frangaise; as head of the company, he  became recognized as the supreme tragedian of the era, winning the admi�  ration of Napoleon.</p><p>Talmud Ual-'miid, 'tal-modX In Judaism, the systematic amplification and  analysis of passages of the Mishna, the Gemara, and other oral law, includ�  ing the Tosefta.

The Babylonian Talmud is more extensive and thus  more highly esteemed. Both Talmuds formulate their own hermeneutics to  convey their theological system by defining the Torah and by demonstrat�  ing its perfection and comprehensive character.

He preferred easel painting to the  monumental proportions and political rhetoric of Jose Clemente Orozco,  Diego Rivera, and David Alfaro Siqueiros. His distinctive style blended  Cubism and Surrealism with Mexican folk-art subjects involving semiab�  stract figures, still lifes, and animals in vibrant colours. From 1936 he  lived principally in New York City. In 1950 an exhibition at the Venice  Biennale brought him international recognition.

The group became identified with the city�s  Democratic Party. The makeup of the society was substantially altered in  1817 when Irish immigrants, protesting Tammany bigotry, forced their  right to membership and benefits. Tammany later championed the exten�  sion of the franchise to white propertyless males. Nevertheless, the soci�  ety�s appeal to particular ethnic and religious minorities, the doling out  of gifts to the poor, and the bribing of leaders of rival political factions,  among them the notorious boss William Marcy Tweed, made the name  Tammany Hall synonymous with political corruption.

It is a winter and fishing resort and major tourist destination; attractions  include Busch Gardens.</p><p>Tampa Bay Inlet, Gulf of Mexico, western Florida, U.S. The bay is 25  mi (40 km) long and 7-12 mi (11-19 km) wide, and it serves the recre�  ational and commercial activities of Saint Petersburg on the western shore  and Tampa on the northeast. Hernando de Soto began his travels through  the southeastern U.S. region when he reached Tampa Bay in 1539. Tampa  Bay is spanned by the 15-mi (24-km) Sunshine Skyway Bridge.</p><p>Tampico \tam-'pe-ko\ Port and city (pop., 2000: 295,442), southeastern  Tamaulipas state, northeastern Mexico. It lies on the Panuco River and is  almost surrounded by swampland and lagoons. It grew around a Fran�  ciscan monastery founded c. 1532. Destroyed by pirates in 1683, it was  not resettled until 1823. It was occupied briefly by U.S. troops (1846)  during the Mexican War and by the French in 1862. Until 1901 it was a  second-rate port with a reputation for unsanitary conditions. It grew with  the rapid exploitation of surrounding petroleum resources to become the  most modem port in Mexico and one of the country�s leading seaports.  It is also a seaside resort.</p><p>Tan Cheng Lock \'tan-'cheq-T6k\ (b. April 5, 1883, Malacca, Straits  Settlements�d. Dec. 8, 1960, Malacca) Malaysian Chinese community  leader and politician.

April 16,  1949, Blitar, Java, Indon.) Indonesian communist leader. A schoolteacher,  he became a communist after returning from Europe in 1919. He was exiled  by the Dutch for trying to incite a general strike in 1922 but returned to Java  in 1944 and, competing with Sukarno for control of the Indonesian nation�  alist movement, created a coalition that briefly came to power in 1946. He  was imprisoned later that year on charges of attempting a coup. In 1948,  while the Dutch and Indonesians were at war, he proclaimed himself head  of Indonesia. Forced to flee the invading Dutch, within a few months he  was captured and executed by Sukarno�s supporters.</p><p>Tana, Lake Lake, Ethiopia. The country�s largest lake, its surface area  covers more than 1,400 sq mi (3,620 sq km). It forms the main reservoir  for the Blue Nile (see Nile River), which pours from it over a lava barrier,  dropping 138 ft (42 m) to form Tisisat Falls. Coptic monasteries were  built on two of its islands during the Middle Ages.</p><p>Tana River \'ta-na\ River, Kenya. The country�s longest river, it rises  in the Aberdare Range and flows in a curve northeast, east, and south 440  mi (708 km) to the Indian Ocean. It is navigable by small craft for about  150 mi (240 km) upstream.</p><p>Tana River Vta-ns\ River, northeastern Norway.

Most species are  4-8 in. (10-20 cm) long and have a short neck. Bills vary in shape, but  all are slightly toothed and hooked. Tanagers have brilliant plumage in  reds, yellows, greens, blues, and black, sometimes strikingly patterned.  Most species are arboreal; most eat fruit, and some eat insects. The scar�  let, summer, and western tanagers breed in temperate North America. The  hepatic tanager breeds from Arizona to central Argentina. Most other spe�  cies are chiefly tropical.</p><p>Tanagra Vta-no-gro, to-'na-groN Ancient town, Boeotia, eastern central  Greece. First occupied by an Athenian clan, it became the chief town of  the eastern Boeotians, with lands extending to the Gulf of Euboea. It was  the scene of the Athenian defeat by the Spartans in 457 bc during the first  Peloponnesian War. Finely modeled terra-cotta statuettes, known as Tana�  gra figures, were made there c. 340-150 bc and exported to Mediterra�  nean countries.</p><p>Tanagra figure Any of the small terra-cotta figures dating primarily  from the 3rd century bc and named after the site in Boeotia, Greece, where  they were found. The statuettes, mostly of well-dressed young women  standing or sitting, were all formed from molds and originally were cov�  ered with a white coating and then painted. On their discovery in the 19th  century, they became enormously popular and were extensively and  expertly forged.</p><p>Tanaka \'ta-na-ka\, Kakuei (b. May 4, 1918, Kariwa, Niigata prefec�  ture, Japan�d. Dec. 16, 1993, Tokyo) Prime minister of Japan (1972-  74). As prime minister, Tanaka pushed through many government  construction projects and was responsible for the economic revitalization  of much of western Japan and for establishing diplomatic relations with  the People�s Republic of China. In 1976 he was charged with accepting,  while prime minister, $2 million from Lockheed Aircraft Corp. to influ�  ence All Nippon Airways to buy Lockheed jets; he was convicted in 1983.  However, he remained powerful in the Liberal-Democratic Party until he  retired from politics in 1990.</p><p>Tanaka Tomoyuki (b. April 16,1910, Osaka, Japan�d. April 2,1997,  Tokyo) Japanese film producer. Tanaka was associated for nearly 60 years  with Japan�s Toho Studios, for which he produced more than 200 films.  Of these, his best known are the 22 films in the Godzilla series, begin�  ning with Godzilla, King of the Monsters in 1954 and ending with Godz�  illa vs. Destroyer in 1995. He also produced films for renowned director  Kurosawa Akira.</p><p>Tanana Yta-no-.noV River River, east-central Alaska, U.S. Rising from  two headstreams fed by glaciers high in the Wrangell Mountains, the</p><p>Tanana flows northwest 550 mi (885 km) to join the Yukon River; it is the  Yukon�s chief southern tributary. The Tanana was first explored by Rus�  sian traders in the mid-19th century. Its valley was an important gold-  producing area in the 1904 gold rush; it is also a lumbering district and  one of Alaska�s major farming regions. The Alaska Highway follows it for  nearly its entire course.</p><p>Tananarive See Antananarivo</p><p>Tancred \'taq-krad\ (d. Feb. 20, 1194, Palermo) King of Sicily (1190�  94), the last of the Norman rulers. He rebelled twice (1155, 1161) against  his uncle William I of Sicily, and he gained the Sicilian throne after the  death of William II. He gave in to the demand of Richard I (the Lionheart)  in 1191 for the legacy left him by William II and the return of the dowry  of his sister Joan, William�s widow, after Richard occupied Messina.  Emperor Henry VI sought to wrest the Sicilian throne from Tancred, unsuc�  cessfully besieging Naples in 1191 and marching on Sicily again in 1194.  Tancred died before his arrival, and Henry was crowned king.</p><p>Tandy, Jessica See Hume Cronyn and Jessica Tandy</p><p>Taney, Roger B(rooke) (b. March 17, 1777, Calvert county, Md.,  U.S.�d. Oct. 12, 1864, Washington,</p><p>D.C.) U.S. jurist. A lawyer from  1801, he served in Maryland�s leg�  islature before being named state  attorney general (1827-31). He was  appointed U.S. attorney general in  1831 by Pres. Andrew Jackson and  achieved national prominence by  opposing the Bank of the United  States. In 1833 Jackson nominated  him to serve as secretary of the trea�  sury, but his appointment was  rejected by the Senate. In 1835 Jack-  son selected him to serve as associ�  ate justice on the Supreme Court of  the United States, and after the death  of Chief Justice John Marshall, Jack-  son sought to have him confirmed as  chief justice. Despite powerful resis�  tance led by Henry Clay, John C. Cal�  houn, and Daniel Webster, Taney was  sworn in as chief justice in March 1836. His tenure (1836-64) remains  the second longest in the Supreme Court�s history. He is remembered  principally for the Dred Scott decision (1857), in which he argued that a  slave was not a citizen and could not sue in a federal court, that Congress  had no power to exclude slavery from the territories, and that blacks could  not become citizens. He is also noted for his opinion in Abelman v. Booth  (1858), which denied state power to obstruct the processes of the federal  courts, and in Charles River Bridge v. Warren Bridge (1837), which  declared that rights not specifically conferred by a charter could not be  inferred from the language of the document. Though he considered sla�  very an evil, he believed its elimination should be brought about gradu�  ally and chiefly by the states in which it existed.</p><p>tang See surgeonfish</p><p>Tang dynasty or T'ang \'taq\ dynasty (618-907) Chinese dynasty  that succeeded the short-lived Sui and became a golden age for poetry,  sculpture, and Buddhism. The Tang capital of Chang'an became a great  international metropolis, with traders and embassies from Central Asia,  Arabia, Persia, Korea, and Japan passing through. A Nestorian Christian  community also existed there, while mosques were established in Guang�  zhou (Canton). The economy flourished in the 8th-9th centuries, with a  network of rural market towns growing up to join the metropolitan mar�  kets of Chang�an and Luoyang. Buddhism enjoyed great favour, and there  were new translations of the Buddhist scriptures and growth of indigenous  sects, including Chan (see Zen). Poetry was the greatest glory of the  period; nearly 50,000 works by 2,000 poets survive. Foreign music and  dance became popular, and ancient orchestras were revived. The Tang  government never completely controlled the northern Chinese border,  where nomad tribes made constant incursions; periodic rebellions from  the mid-8th century onward also weakened its power (see An Lushan  Rebellion). In its later years, the government�s focus was on eastern and  southeastern China rather than Central Asia. See also Taizong; Wu Hou.</p><p>Roger B.

Tange worked in the office of Maekawa  Kunio before setting out on his own. His first major commission involved  the reconstruction of Hiroshima. In addition to planning the city, he helped  design Hiroshima�s Peace Memorial Park, and its peace centre (1950) and  museum (1952) are among his best-known early works. His Kagawa pre-  fectural offices in Takamatsu (1958) were a particularly fine blend of the  modern and traditional. In 1959 Tange and his students published the Bos�  ton Harbor project, launching the Metabolist school. His work in the 1960s  took on more boldly dramatic forms, and he became a master at manipu�  lating complex geometries; his National Gymnasiums for Tokyo�s 1964  Olympic Games are exemplary. During 1966-70 he designed the master  plan for the Japan World Exposition (Expo 70), which was held in Osaka.  More-recent works include the New Tokyo City Hall Complex (1991) and  the Tokyo Dome Hotel (2000). Also influential as a writer, teacher, and  town planner, Tange was awarded the Pritzker Architecture Prize in 1987.</p><p>tangent See trigonometric function</p><p>tangent line Vtan-jont\ In geometry, a line that intersects a circle  exactly once; in calculus, a line that touches a curve at one point and  whose slope is equal to that of the curve at that point. Particularly useful  as approximations of curves in the immediate vicinity of the point of tan-  gency, tangent lines are the basis of many estimation techniques, includ�  ing linear approximation. The numerical value of the slope of the tangent  line to the graph of a function at any point equals that of the function�s  derivative at that point. This is one of the keystones of differential calculus.

Probably  native to Southeast Asia, today it is  cultivated in subtropical regions  worldwide, especially southern  Europe and the southern U.S. The  tree is smaller than other orange  trees, with slender twigs and lance�  shaped leaves. The fruit is slightly  flattened at each end and has a loose,  reddish orange peel. Easily separated  segments of tender, juicy, richly fla�  voured pulp are abundant in vitamin  C. Oil from the fragrant skin is a  characteristic ingredient in several  flavourings and liqueurs. The tanger�  ine crossed with the grapefruit produced the hybrid known as the tangelo.</p><p>Tangier \tan-'jir\ French Tanger \ta n -'zha\ Arabic Tanjah \'tan-jo\  ancient Tingis Seaport city (pop., 1994: 521,735), northern Morocco.  Located at the western end of the Strait of Gibraltar, it was first known  as an ancient Phoenician trading post and later became a Carthaginian  and then a Roman settlement. After five centuries of Roman rule, it was  captured successively by the Vandals, Byzantines, and Arabs. It fell to the  Portuguese in 1471; it later passed to the British, who gave it up to  Morocco in 1684. When the rest of Morocco became a French protector�  ate in 1912, Tangier was granted special status; in 1923 it officially became  an international city, governed by an international commission. It  remained an international zone until it was integrated in 1956 with the  independent kingdom of Morocco. It became a free port and royal sum�  mer residence in the 1960s. The old town is dominated by a Casbah (cita�  del) and the Great Mosque. It is a busy port and trade centre; industries  include tourism, fishing, and textiles, especially carpets.</p><p>tango Spirited Spanish flamenco dance; also a South American ballroom  dance. It evolved into a ballroom dance in Buenos Aires, Arg., possibly  influenced by the Cuban habanera. It was made popular in the U.S. by  Vernon and Irene Castle, and by 1915 it was being danced throughout  Europe. Early versions were fast and exuberant; these were later modi�</p><p>fied to the smoother ballroom step,  characterized by long pauses and  stylized body positions and danced  to music in 4 A time.</p><p>Tangun \'tan-'gun\ Mythological  first king of the Koreans, whose reign  began in 2333 bc.

Jan. 5, 1900, Paris, France�d. Jan. 15, 1955  Waterbury, Conn., U.S.) French painter. In 1923, after serving in the mer�  chant marine, he was inspired to start painting when he saw the works of  Giorgio de Chirico, though he had no formal art training. He joined the  Surrealist group in 1925 and participated in all their major exhibitions.  He developed a unique style, reminiscent of Salvador Dali�s, depicting  strange, amorphous creatures and unidentifiable objects set in barren,  brightly lit landscapes with infinite horizons. Despite their smooth, pains�  taking detail, his pictures have a timeless, dreamlike quality (e.g.. The  Invisibles, 1951). He emigrated to the U.S. in 1939.</p><p>Tanimbar Islands Uo-'nim-.bar, 'ta-nom-.barN Group of about 30  islands, southeastern Moluccas, Indonesia. It includes the large island of  Jamdena, 70 mi (113 km) long by 28 mi (45 km) wide, and the nearby  islands of Larat and Selaru. Though there is a lack of fresh water, the soil  supports com, rice, coconut palms, and fruits. The Dutch claimed the  group in 1639 but did not establish rule until 1900. After World War II,  the islands became part of Indonesia.</p><p>Tanis Vta-n9s\ biblical Zoan Ancient city, Egypt. Its remains are located  in the Nile River delta. Capital of a province of Lower Egypt and, under the  21st and 22nd dynasties (c. 1075-c. 700 bc), of the whole country, it was  important as one of the ports nearest to the Asian seaboard. In 1939 several  intact royal tombs containing silver coffins, gold masks, and gold and silver  jewelry were excavated within the ancient main temple enclosure.</p><p>Tan it \'ta-nit\ Chief goddess of Carthage, the equivalent of Astarte. She  first appeared around the 5th century bc. Though she seems to have had  some connection with the heavens, she was also a mother goddess and  symbol of fertility. She was the consort of Baal Hammon, chief god of  Carthage, whose cult she eventually eclipsed. Archaeological evidence  suggests that children, probably firstborn, were sacrificed both to her and  to Baal Hammon. Outside Carthage, Tanit also enjoyed a following on  Malta, on Sardinia, and in Spain.</p><p>Tanizaki Jun'ichiro X.ta-ne-'za-ke-'jim-e-.che-roV (b. July 24, 1886,  Tokyo, Japan�d. July 30, 1965, Yugawara) Japanese novelist. Though  his earliest short stories have affinities with those of Edgar Allan Poe and  the French Decadents, Tanizaki later turned to exploring more traditional  Japanese ideals of beauty. His novels include Some Prefer Nettles (1928�  29), which tells of marital unhappiness that is in fact a conflict between  the new and the old, with the implication that the old will win; and his  masterpiece, The Makioka Sisters (1943-48; film, 1983), which describes,  in the leisurely style of classical Japanese literature, the inroads of the  harsh modern world on traditional society.

It is usually equipped with a can�  non mounted in a revolving turret as well as lighter automatic weapons.  The British developed tanks during World War I to fill the need for an  armoured assault vehicle that could cross the muddy, uneven terrain of  the trench battle zone. They first saw combat at the Battle of the Somme  (1916). In World War II, Germany�s tank force was initially the most  effective in Europe because it was organized into fast-moving massed  formations with great striking power. After World War II, tanks became  larger and more heavily armed. Most modern main battle tanks weigh  more than 50 tons yet are capable of road speeds of 30-40 mph (50-70  kph). The standard main armament is a 120-mm gun, which fires armour-  piercing projectiles; laser range-finders and infrared imaging devices aid  in sighting.</p><p>Tannenberg Vta-non-.berkN, Battle of (July 15, 1410) Major Polish-  Lithuanian victory over the Knights of the Teutonic Order.

He moved to Paris in 1891, and by 1894 his work was being exhib�  ited at the annual Salons, where he was awarded honourable mention in  1896 for Daniel in the Lions� Den and won a medal in 1897 for his Raising  of Lazarus. He gained international acclaim and many awards for his land�  scapes and his treatments of biblical themes.

A professional minnesinger, Tannhauser served sev�  eral noble patrons; a few of his works are extant. In the legend preserved  in a popular ballad, �Danhauser,� he lives a life of pleasure but, torn by  remorse, goes to Rome to seek remission of his sins. The pope tells him  that, as his pilgrim�s staff would never put on leaf again, so his sins can  never be forgiven. Shortly afterward his discarded staff puts forth green  leaves. The pope sends messengers to search for him, but he is never seen  again. The legend, popular among 19th-century Romantic writers, was  retold in Richard Wagner�s opera Tannhauser (produced 1845).</p><p>tannin or tannic acid Any of a group of pale yellow to light brown  amorphous substances widely distributed in plants and used chiefly in  tanning leather, dyeing fabric, and making ink. Their solutions are acid  and have an astringent taste. They are isolated from oak bark, sumac,  myrobalan (an Asian tree), and galls. Tannins give tea astringency, colour,  and some flavour. Tannins are used industrially to clarify wine and beer,  reduce viscosity of oil-well drilling mud, and prevent scale in boiler water;  they have also had medical uses.</p><p>tanning Chemical treatment of raw animal hides or skins to convert  them into leather. Vegetable tanning (using bark, wood, roots, or berries)  has been practiced since prehistoric times. After removal of hair, flesh, or  fat, a tanning agent displaces water from the interstices between the pro�  tein (mostly collagen) fibres in the skin and cements the fibres together.  The agents most widely used are vegetable tannin, salts such as chromium  sulfate, and fish or animal oil. The tanning of fair skin in humans by sun�  light is completely different: ultraviolet light causes production and redis�  tribution of the pigment melanin in epidermal cells.</p><p>tansy Vtan-ze\ Any of about 50 species of strong-smelling, poisonous  herbs, especially common tansy ( Tanacetum vulgare, or Chrysanthemum  vulgare), of the composite family, native to the northern temperate zone. T.  vulgare has button-shaped yellow flower heads of disk flowers (no ray  flowers) that are arranged in a flat-topped cluster, deeply cut leaves, and</p><p>many stems. It is sometimes cultivated in herb gardens and was formerly  used in medicines and insecticides.

It is a dense, hard, unre�  active, silvery gray metal with an extremely high melting point (5,425 �F  [2,996 �C]). Relatively rare, it occurs native in a few places. It is difficult  to separate from niobium, the element above it in the periodic table, with  which it shares many properties. The most important uses are in electro�  lytic capacitors, corrosion-resistant chemical equipment, dental and sur�  gical instruments, tools, catalysts, components of electron tubes, rectifiers,  and prostheses. Its compounds are relatively unimportant commercially;  tantalum carbide is used in machine tools and dies.</p><p>Tantalus \'tan-t 3 l-os\ In Greek mythology, the king of Sipylus (or Phry�  gia). An intimate friend of the gods, he was allowed to dine at their table  until he offended them by repeating their secrets on earth. Another ver�  sion of the myth held that he killed his son Pelops and served him to the  gods. In the underworld he was placed up to his neck in water, which  flowed away every time he tried to drink, just as the branches overhead  swung out of reach whenever he tried to pick the fruit from them.</p><p>tantra Vton-troV In some Indian religions, a text that deals with esoteric  aspects of religious teaching. There is considerable tantric literature and  practice in Hinduism, Buddhism, and, to a lesser extent, Jainism. Because  tantric practices typically represent teachings of relatively late develop�  ment and incorporate elements of different traditions, they are often  eschewed by orthodox practitioners. In Hinduism, tantras deal with popu�  lar aspects of the religion, such as spells, rituals, and symbols. Buddhist  tantric literature, believed to date from the 7th century or earlier, has ref�  erence to numerous practices, some involving sexual activity, that have  no basis in canonical literature.</p><p>Tanzania \,tan-z3-'ne-3\ officially United Republic of Tanzania</p><p>Country, eastern Africa.

Serengeti National Park is the  most famous of its extensive game reserves. Important mineral deposits  include gold, diamonds, gemstones, coal, and natural gas. The centrally  planned economy is based largely on agriculture; major crops include corn,  rice, coffee, cloves, cotton, sisal, cashews, and tobacco. Industries include  food processing, textiles, cement, and brewing. Tanzania is a republic with  one legislative house; its head of state and government is the president.  Inhabited from the 1st millennium bc, it was occupied by Arab and Indian  traders and BANTU-speaking peoples by the 10th century ad. The Portuguese  gained control of the coastline in the late 15th century, but they were driven  out by the Arabs of Oman and Zanzibar in the late 18th century. German  colonists entered the area in the 1880s, and in 1891 the Germans declared  the region a protectorate as part of German East Africa. During World War  I, Britain captured the German holdings, which became a British mandate  (1920) under the name Tanganyika. Britain retained control of the region  after World War II when it became a UN trust territory. Tanganyika gained  independence in 1961 and became a republic in 1962. In 1964 it united with  Zanzibar under the name Tanzania and was led by Pres. Julius Nyerere until  1985. The country subsequently experienced both political and economic  struggles; it held its first multiparty elections in 1995.</p><p>Tanzimat \,tan-ze-'mat\ (Turkish: �Reorganization�) (1839-76) Series  of reforms undertaken in the Ottoman Empire to modernize society along  secular and bureaucratic lines. The first set of reforms (1839) sought to  secularize the government�s treatment of people and property and to  reform taxation and military conscription. Later reforms (1856) estab�  lished a secular school system and a new law code. Efforts to centralize  government administration, however, ended by concentrating all author�  ity in the hands of the sultan, who often abused the power. The consti�  tution of 1876, while promising democratic reforms, actually was  intended to stave off European intervention.

He became a tutor to the imperial court while still a youth. In  492 he retired to a mountain retreat at Mao Shan to devote himself to the  study of Daoism. His research in proper eating and living practices led  him to write one of the major pharmacological works of China. He also  edited and annotated the religious writings of his major Daoist predeces�  sors, producing Declarations of the Perfected and Secret Instructions for  Ascent to Perfection.</p><p>Tao-te ching See Daodejing  Taoism See Daoism</p><p>Taos \'taus\ Town (pop., 2000: 4,700) and resort, northern New Mexico,  U.S. Located on a branch of the Rio Grande in the Sangre de Cristo Moun�  tains, Taos is composed of three villages: Don Fernando de Taos (known  as Taos), the pueblo of San Geronimo (Taos Pueblo), and the Ranchos de  Taos. An early Spanish settlement, it was the scene of a revolt (1680) of  Taos and other Pueblo Indians against Spain and later was an important  commercial centre on the Santa Fe Trail. In the 20th century artists and  writers moved there, including D.H. Lawrence. Lawrence�s home and that  of Kit Carson are historic sites; Carson�s grave is in a memorial state park.</p><p>tap dance Style of American theatrical dance using precise rhythmical  patterns of foot movement and audible foot tapping. It is derived from the  traditional clog dance of northern England, the jigs and reels of Ireland  and Scotland, and the rhythmic foot stamping of African dances. Popular  in 19th-century minstrel shows, versions such as �buck-and-wing� (danced  vigorously in wooden-soled shoes) and �soft-shoe� (danced smoothly in  soft-soled shoes) developed as separate techniques; by 1925 they had  merged, and metal taps were attached to shoe heels and toes to produce  a more pronounced sound. The dance was also popular in variety shows  and early musicals.</p><p>Tapajos \,ta-pa-'zh6s\ River River, northern Brazil. Formed by the  confluence of the Teles Pires and the Juruena rivers, it flows northeast to  empty into the Amazon River just above Santarem after a course of about  400 mi (650 km). Though interrupted by rapids, its entire length is navi�  gable. Several important rubber plantations lie along its banks.</p><p>tapas Vt3-p3s\ Ascetic practice carried out to achieve spiritual power or  purification. In Hinduism, it is associated with Yoga as a way of purifying</p><p>the body in preparation for the more exacting spiritual exercises leading  to liberation. In Jainism, its practice is a central means of breaking the cycle  of rebirths by preventing new karma from forming and by eliminating the  old. Tapas can take many forms, including fasting, controlling the breath,  and holding difficult and painful body postures. Extreme forms are car�  ried out by sadhus, many of whom earn alms for their unusual abilities or  deprivations.</p><p>tape recorder Recording system that makes use of electromagnetic  phenomena to record and reproduce sound waves. The tape consists of a  plastic backing coated with a thin layer of tiny particles of magnetic pow�  der. The recording head of the tape deck consists of a tiny C-shaped mag�  net with its gap adjacent to the moving tape. The incoming sound wave,  having been converted by a microphone into an electrical signal, produces  a time-varying magnetic field in the gap of the magnet. As the tape moves  past the recording head, the powder is magnetized in such a way that the  tape carries a record of the shape of the wave being recorded.</p><p>tapestry Heavy, reversible, patterned or figured hand-woven textile,  usually in the form of a hanging or upholstery fabric. Tapestries are usu�  ally designed as single panels or as sets of panels related by subject and  style and intended to be hung together. The earliest known tapestries were  made from linen by the ancient Egyptians. Tapestry weaving was well  established in Peru by the 6th century, and outstanding silk tapestries were  made in China beginning in the Tang dynasty (ad 618-907). In western  Europe, tapestry making flourished from the 13th century. Among the  greatest European tapestries are the 15th-century Lady with the Unicorn  set and the 16th-century Acts of the Apostles set, based on cartoons by  Raphael. Tapestry art was revitalized in late-19th-century Britain with the  Arts and Crafts Movement. In the 20th century, abstract tapestries were  produced at the Bauhaus, and many painters, including Pablo Picasso and  Henri Matisse, allowed their paintings to provide the basis for tapestry art.</p><p>tapeworm Any of about 3,000 species (class Cestoda, phylum Platy-  helminthes) of bilaterally symmetrical parasitic flatworms found world�  wide. Tapeworms range from 0.04 in. (1 mm) to more than 50 ft (15 m)  long. The head bears suckers and often hooks for attaching to the liver or  digestive tract of the host. Once attached, a tapeworm absorbs food  through its body wall. The body is often divided into a head, or scolex,  possessing the suckers and hooks, an unsegmented neck, and a series of  proglottids (units containing both male and female reproductive organs)  that continually form in a growth region at the base of the neck. Follow�  ing fertilization, each mature proglottid containing thousands of embryos  breaks off and is eliminated in the host�s feces. If these are ingested by  an animal (the intermediate host) grazing on food contaminated with  feces, they develop into larvae, which bore through the intestinal wall into  the circulatory system and are carried to muscle tissues, which they bur�  row into, forming a dormant cyst. When meat is inadequately cooked,  humans become infested with the larvae, which attach to the intestinal  wall. Many species that infest humans belong to the genus Taenia', the  intermediate host is implied by the name (e.g., beef tapeworm, T. sagi-  nata ). Humans can also acquire tapeworms through fecal contamination  of soil or water. See illustration on the following page.</p><p>Tapi \'ta-pe\ River or Tapti River Vtap-te\ River, west-central India.

Dec. 13, 1923, Barcelona, Spain) Catalan  painter. In 1946 he abandoned the study of law to devote his time to paint�  ing, which he taught himself. His early works were influenced by Surreal�  ism, Paul Klee, and Joan Miro. In 1953, after seeing the works of Jean  Dubuffet, he developed a unique blend of abstraction, assemblage, and  impasto that established his interna�  tional reputation. He has produced  lithographs and illustrated books; his  belief in the validity of commonplace  materials has had worldwide influ�  ence. In 1990 the Tapies Foundation,  housing some 2,000 of his works,  opened in Barcelona.</p><p>tapir Vta-p9r\ Any of four extant  members (genus Tapirus ) of the fam�  ily Tapiridae, heavy-bodied, odd�  toed ungulates, 6-8 ft (1.8-2.5 m)</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Tappan &#x25BA; Tarantino I 1873</p><p>rostellum scolex</p><p>Principal features of the beef tapeworm (Taenia saginata).

He operated various businesses, including a silk-importing firm  in New York (1826-37) with his brother Lewis Tappan (1788-1873); they  also founded the first commercial credit-rating service (1841). He used  his wealth to support missionary societies and the abolitionist crusade,  helping found the American Anti-Slavery Society and serving as its first  president (1833-40). After breaking with William Lloyd Garrison, he cre�</p><p>ated the American and Foreign Anti-Slavery Society (1840). The Tappan  brothers later supported the Underground Railroad.</p><p>taproot Main root of a primary-root system. It grows vertically down�  ward. From the taproot arise smaller lateral roots (secondary roots), which  in turn produce even smaller lateral roots (tertiary roots). Most dicotyle�  donous plants (see cotyledon), such as dandelions, produce taproots. The  system may be modified into a fibrous, or diffuse, system, in which the  initial secondary roots soon equal or exceed the primary root in size and  there is no well-defined single taproot. Fibrous root systems are generally  shallower than taproot systems. Carrots and beets are tuberous roots modi�  fied from taproots.</p><p>Tapti River See Tapi River</p><p>taqiyyah \to-'ke-3\ In Islam, the practice of concealing one�s faith and  forgoing ordinary religious duties under threat of death or injury to one�  self or one�s fellow Muslims. Its basis is found in the Qur�an, and Muham�  mad is regarded as having set its first example when he chose to make the  Hijrah. It has since been practiced mostly among minority groups, par�  ticularly those of the ShTite branch. Various rules governing its applica�  tion are meant to ensure that taqiyyah does not become an excuse for  cowardice or for failure to take appropriate action. Consideration of com�  munity rather than private welfare is generally stressed.</p><p>taqlld \ta-'kled\ In Islamic canon law, the unquestioning acceptance of  legal precedent. The interpretation of taqlid varies widely among the  major schools of Islamic law. Taqlld is compulsory for Shi*ites. Of the four  Sunnite legal schools, views are mixed; most scholars of the ShafiT,  MalikI, and Hanafi schools embrace taqlld, but those of the Hanbal! do  not view the opinions of earlier scholars as necessarily binding. Support  for the practice is based mainly on the belief that early Muslim scholars,  being closer in time to Muhammad, were in the best position to derive  authoritative legal opinions.</p><p>tar sand or bituminous sand Deposit of loose sand or partially  consolidated sandstone that is saturated with highly viscous bitumen.

Located on the Gulf of Taranto,  the old city is on a small island, with newer areas on the adjacent main�  land. Founded by SpARTAns in the 8th century bc, it was called Taras and  became one of the leading cities of Magna Graecia. It reached its zenith  in the 4th century bc under Archytas. It came under Rome in 272 bc.  Between the 5th and the 11th centuries ad it was taken by the Goths, Byz�  antines, Lombards, Arabs, and Normans. By the 15th century it was part  of the Kingdom of Naples. It became part of the Kingdom of the Two Sicil�  ies from 1815 and then joined the Kingdom of Italy in 1861. Taranto was  an important stronghold of the Italian navy in both world wars; it was  heavily bombed in 1940 and was occupied by British forces in 1943. Still  an important naval base, it is the site of extensive shipyards and a large  iron- and steelworks.</p><p>tarantula \t9-ran-ch9-lo\ Name that originally referred to the wolf spi�  der but now covers any spider in the  family Theraphosidae. It is found  from the southwestern U.S. to South  America. Many species live in a bur�  row, and most have a hairy body and  long, hairy legs. They are nocturnal  predators of insects and, occasion�  ally, amphibians and mice. Certain  South American tarantulas eat small  birds. In the southwestern U.S.,  tarantulas of the genus Aphonopelma  may have a body 2 in. (5 cm) long  and a leg spread of nearly 5 in. (12  cm). They may inflict a painful bite  if provoked. The most common U.S.  species, Eurypelma califomicum,  may live up to 30 years.</p><p>Tarasco or Tarascan Indian people of Michoacan state in central  Mexico. Traditionally, they have been farmers, though they fish, hunt,  trade, and work for wages as well. Each village tends to specialize in a  craft (e.g., woodworking, weaving, pottery, net weaving, embroidering,  or sewing). Their Roman Catholicism is only slightly influenced by pre-  Columbian religion. They are gradually becoming assimilated to the mes�  tizo culture, though their primary language remains Tarascan.</p><p>Tarawa Us-'ra-ws, 'ta-rs-waX Coral atoll (pop., 1995: 32,354), Gilbert  Islands, Kiribati.

She  became best known for The History of the Standard Oil Company (1904),  an account of the rise of a business monopoly that first appeared serially  in McClure�s Magazine and led to the government�s epochal antitrust suit  against the company. For her work Tarbell became one of the journalists  Theodore Roosevelt dubbed muckrakers.</p><p>Tardieu \tar-'dyoe\, Andre (-Pierre-Gabriel-Amedee) (b. Sept.  22, 1876, Paris, France�d. Sept. 15, 1945, Menton) French politician.  After work in the diplomatic service, he became foreign editor of Le  Temps and was elected to the Chamber of Deputies in 1914. A delegate  to the Paris Peace Conference, he was instrumental in drafting the Treaty  of Versailles. A supporter of Georges Clemenceau in his early career, he  served in various government posts, and as the leader of the right-centre  in the Chamber of Deputies, he twice served as premier (1929-30, 1932),  advocating a policy of large national expenditure. Disillusioned with the  failures of the parliamentary system, he retired in 1936.</p><p>Targum \'tar-gam\ Any of several translations of the Hebrew scriptures  or its parts into Aramaic. The earliest date from after the Babylonian Exile  and were designed to meet the needs of uneducated Jews who did not  know Hebrew. After the destruction of the Second Temple of Jerusalem  (ad 70), Targums became established in synagogues, where scripture was  read aloud with a translation in Aramaic. These readings eventually incor�  porated paraphrase and commentary. Targums were regarded as authori�  tative throughout the Talmudic period (see Talmud) and began to be  committed to writing in the 5th century.</p><p>Tarhun \'tar-,kun\ or Taru \'tar-,u\ Ancient Anatolian weather god  whose name appeal's in records as early as 1400 bce. He was one of the  supreme deities of the Hittite pantheon and was regarded as the embodi�  ment of the state in action. He was the consort of Arinnitti, the Hittite sun  goddess and principal deity. His sacred animal is the bull, and in art he  may be depicted standing on one. Jupiter Dolichenus arose as a develop�  ment of Tarhun.</p><p>tariff or customs duty Tax levied upon goods as they cross national  boundaries, usually by the government of the importing country. The  words tariff, duty, and customs are generally used interchangeably. Usu�  ally assessed on imports, tariffs may apply to all foreign goods or only to  goods produced outside the borders of a customs union. A tariff may be  assessed directly, at the border, or indirectly, by requiring the prior pur�  chase of a license or permit to import specified quantities of the good.  Examples of tariffs include transit duties and import or export taxes, which  may be levied on goods passing through a customs area en route to another  destination. In addition to providing a source of revenue, tariffs can effec�  tively protect local industry by driving up the price of an imported item  that competes with domestic products. This practice allows domestic pro�  ducers either to charge higher prices for their goods or to capitalize on  their own lighter taxes by charging lower prices and attracting more cus�  tomers. Tariffs are often used to protect �infant industries� or to safeguard  older industries that are in decline. They are sometimes criticized for  imposing hidden costs on domestic consumers and encouraging ineffi�  ciency in domestic industries. Tariffs are subject to negotiation and trea�  ties among nations (see General Agreement on Tariffs and Trade; trade  agreement; World Trade Organization).</p><p>Tarim \'da-'rem\ River Chinese Talimu \'ta-Te-'mu\ He or T'a-li-mu</p><p>Ho Chief river of Xinjiang autonomous region, China.

Each suit has 10 num�  bered cards and 4 court cards (king,  queen, knight, and page). Modern  playing cards evolved from these suit  cards. Initially used as playing cards,  tarot cards were imbued with eso�  teric associations in the 18th century  and are now used widely for fortune�  telling. Each card�s basic meaning is  altered by the card�s position in the  spread of cards laid out by the  fortune-teller, by the card�s orienta�  tion, and by the cards that are near it.</p><p>tarpon Any of certain marine fish  (family Megalopidae) having an  elongated last dorsal fin ray and a  bony throat plate between the sides  of the protruding lower jaw.

In 67 bc it  was absorbed into the new Roman province of Cilicia, becoming its prin�  cipal city. It was the site of the first meeting in 41 bc between Mark An�  tony and Cleopatra and was the birthplace of St. Paul. It remained a leading  industrial and cultural centre through the early Byzantine period. It came  under various powers in the 10th-15th centuries and passed to the Otto�  man Empire in the early 16th century. Modem Tarsus is a prosperous  agricultural and cotton-milling centre.</p><p>tartan Cross-checkered repeating pattern (or �sett�) of bands, stripes, or  lines of various colours and of defi�  nite width and sequence, woven into  woolen cloth, sometimes with silk  added.

The practice of attributing human characteristics to the deity  is regarded as a sin in Islamic theology, as is its opposite, ta'til (divesting  God of all attributes). The difficulty of dealing with the nature of God in  Islam arises from seemingly contradictory views in the Qur�an, which  describes God as unique, yet also refers to him as having eyes, ears, hands,  and face. Tashblh is forbidden out of the fear that its practice will lead to  paganism and idolatry; ta'tll is feared to lead to atheism.</p><p>Tashkent \tash-'kent, tash-'kend\ or Toshkent City (pop., 1998 est.:  2,124,000), capital of Uzbekistan.

In the service of the Dutch East India Company, he made explor�  atory and trading voyages to East and Southeast Asia (1634-39). In 1642  he was sent by Anthony van Diemen to find the hypothetical southern con�  tinent of the Pacific and a possible route to Chile. Sailing from Batavia  (modern Jakarta), he reached 49� S at 94� E, then turned north and dis�  covered land he named Van Diemen�s Land (Tasmania), then sailed along  the coast of New Zealand, believing it to be the southern continent. He  also discovered Tonga and the Fiji Islands. On his next voyage (1644) he  sailed into the Gulf of Carpentaria and along the northern and western  coasts of Australia.</p><p>Tasman Peninsula \'taz-mon\ Peninsula, southeastern Tasmania, Aus�  tralia. About 26 mi (42 km) long by 20 mi (32 km) wide, it has sea cliffs  and unusual rock formations. First explored in 1642, it was not settled  until a penal colony was established at Port Arthur in 1830. Its partly  restored ruins are now a tourist attraction, and the peninsula is part of  Australia�s National Estate.</p><p>Tasman Sea Part of the South Pacific Ocean, between southeastern  Australia and western New Zealand. About 1,400 mi (2,250 km) wide, it  has maximum depths exceeding 17,000 ft (5,200 m) in the Tasman Basin.  Explored by Abel Janszoon Tasman in 1642 and by Capt. James Cook in  the 1770s, it is notoriously stormy. Economic resources include fisheries  and petroleum deposits.</p><p>Tasmania \taz-ma-ne-d\ formerly Van Diemen's Vde-monzX Land  Island (pop., 2005 est.: 485,199) and state, Australia. Located off the  southeastern comer of the continent and separated from it by Bass Strait,  the state has an area of 26,410 sq mi (68,400 sq km) that also includes  numerous smaller islands. Hobart is the capital. Originally inhabited by  Australian Aboriginals, the island was explored and named Van Diemen�s  Land by Abel Janszoon Tasman in 1642. Taken by the British in the early  1800s and made a colony in 1825, it was used as an auxiliary penal settle�  ment until the 1850s. It was granted self-government and renamed Tas�  mania in 1856; it became a state of the Australian Commonwealth in 1901.  Chief economic activities include copper, zinc, tin, and tungsten mining;  livestock raising, especially sheep for wool; and tourism. Several natural  areas, collectively called the Tasman Wilderness, were designated a  UNESCO World Heritage site in 1982 (extended in 1989).</p><p>Tasmanian Any member of a now-extinct population of Tasmania. An  isolate population of Australian Aboriginals who entered Tasmania  25,000-40,000 years ago, they were cut off from the mainland when a  general rise in the sea level flooded the Bass Strait about 10,000 years  ago. Subsistence was based on hunting land and sea mammals and col�  lecting shellfish and vegetable food. The first permanent white settlement  was made in Tasmania in 1803, and the settlers provoked a war in 1804.  Of an estimated 4,000 Tasmanians present when the Europeans first  arrived, only 200 remained by the 1830s; moved to Flinders Island for  their protection, they did not survive long in their new home, and the last  full-blooded Tasmanian died in 1876.</p><p>Tasmanian devil Marsupial spe�  cies ( Sarcophilus harrisii or S. ursi-  nus, family Dasyuridae), now extinct  on the Australian mainland, that sur�  vives in remote rocky areas of Tas�  mania. It is 30^10 in. (75-100 cm)  long, with a stocky body, large head  and jaws, and long bushy tail. The  coat is usually black and brown with  a white-marked breast. Named for its  devilish expression and husky snarl, Tasmanian devi | ( s arcop f,;/ us harrisii).  it is mainly a scavenger of wallaby JO hn yates/shostalassociates</p><p>and sheep carcasses but also eats beetle larvae and occasionally poultry. Its  three or four young remain in the mother�s pouch about five months.</p><p>Tasmanian wolf or Tasmanian tiger or thylacine Extinct, slen�  der, fox-faced marsupial ( Thylacinus cynocephalus, family Thylacinidae),  40-50 in. (100-130 cm) long. It was yellowish brown, with dark bars on  the back and rump. It hunted at night for wallabies and birds. The female  carried her young in a shallow pouch. Once found on the Australian  mainland and New Guinea, it was confined to Tasmania in historical  times, when competition with the dingo led to its disappearance from the  mainland. Europeans in Tasmania hunted it to protect their sheep; the last  known individual died in captivity in 1936.</p><p>Tasso Vtas-scA, Torquato (b. March 11, 1544, Sorrento, Kingdom of  Naples�d. April 25, 1595, Rome) Italian poet. The son of a poet and  courtier, Tasso became a courtier of Duke Alfonso II d�Este at Ferrara.  In a period of intense poetic activity he produced the pastoral drama  L�Aminta (1581; performed 1573), a lyrical idealization of court life. In  1575 he completed his celebrated masterpiece on the First Crusade,  Gerusalemme liberata (1581; Jerusalem Delivered), a heroic epic in  ottava rima that blends historical events with imaginary romantic and  idyllic episodes. He developed a persecution mania and from 1579 to 1586  was incarcerated in a hospital by order of the duke. Gerusalemme was  translated and imitated in many European languages, and Tasso was the  subject of literary legend for centuries. He is regarded as the greatest Ital�  ian poet of the late Renaissance.</p><p>taste or taste perception Special sense for perceiving and distin�  guishing the sweet, sour, bitter, or salty quality of a dissolved substance,  mediated by taste buds on the tongue. More than 9,000 taste buds on the  tongue are responsible for the chemoreception of taste. Some taste buds are  also found on the roof of the mouth and throat. See illustration on fol�  lowing page.</p><p>Tatar Vta-tor\ or Tartar Any member of the Turkic-speaking peoples  who today live mainly in west-central Russia east to the Ural Mountains,  in Kazakhstan, and in western Siberia. They first appeared as nomadic  tribes in northeastern Mongolia in the 5th century. Some joined the armies  of Genghis Khan. Especially identified with the Golden Horde, they were  converted to Islam in the 14th century. The Golden Horde soon became  independent Tatar khanates (see khan). Their economy was based on  mixed farming and herding, which remain central to their economy. They  developed craftsmanship in wood, ceramics, leather, cloth, and metal and  have been well known as traders. Today there are about six million Tatars  in all regions; they constitute about half the population of the Russian  republic of Tatarstan.

Its speakers include less than  half the population of Tatarstan in Russia, with the remainder scattered in  enclaves across eastern European Russian, Siberia, and the Central Asian  republics. Tatar, like the closely related Bashkir language, is characterized  by a remarkable series of vowel shifts that distinguish it (at least in its most  characteristic varieties) from all other Turkic languages. It has numerous  dialect distinctions; the conventional division is between a central group  that includes the Tatar of most of Tatarstan and the literary language based  on Kazan speech, a western group, and an eastern group. Crimean Tatar,  belonging to the southwestern group of Turkic languages, and Chulym  Tatar, belonging to the northeastern group, are not closely related to Tatar.</p><p>Tatar Strait Vta-,tar\ Wide passage in the northwestern Pacific Ocean,  connecting the Sea of Japan (East Sea) and the Sea of Okhotsk.

From 1934 he taught at several  institutions, including Princeton University and the University of Minne�  sota, becoming a leading exponent of the New Criticism. He emphasized  the writer�s need for tradition, which he found in Southern culture and  later in Roman Catholicism, to which he converted in 1950.

After a visit to Paris (1914), he became the  leader of a group of Moscow artists who sought to apply engineering  techniques to sculpture construction, a movement that developed into  Constructivism. He pioneered the use of iron, glass, wood, and wire in  nonrepresentational constructions. His Monument to the Third Interna�  tional, commissioned by the Soviet government, was one of the first  buildings conceived entirely in abstract terms and was intended to be, at  more than 1,300 ft (400 m), the world�s tallest structure. A model was  exhibited at the 1920 Soviet Congress, but the government disapproved  of nonfigurative art and it was never built. After 1933 Tatlin worked  largely as a stage designer.</p><p>tattoo Permanent mark or design made on the body by pigment intro�  duced through ruptures in the skin. The term is also loosely applied to the  inducement of scars (cicatrization). Tattooing has been practiced in most  parts of the world, and examples have been found on Egyptian and Nubian  mummies dating from 2000 bc. Decoration is perhaps the most common  motive, though designs may also serve to identify rank, status, or mem�  bership and are thought by some to provide magical protection against  sickness or misfortune. The word comes from Tahiti, where it was  recorded by James Cook�s expedition in 1769. The first electric tattooing  implement was patented in the U.S. in 1891.</p><p>Tatum \'ta-tom\, Art(hur) (b.

Influenced by Fats Waller and Earl Hines, his playing represents a  synthesis of stride and swing piano traditions. He developed an unprec�  edented technical and harmonic control on the instrument and was capable  of astonishing speed and intricate elaborations of melody. By 1937 he was  recognized as the outstanding pianist in jazz. He formed a trio with gui�  tar and bass in 1943 but frequently made solo performances that show�  cased his unique mastery.</p><p>Tatum, Edward L(awrie) (b. Dec. 14, 1909, Boulder, Colo.,  U.S.�d. Nov. 5, 1975, New York, N.Y., U.S.) U.S. biochemist. He  worked with George Wells Beadle at Stanford University, where they con�  firmed that all biochemical processes in organisms are ultimately con�  trolled by genes, that these processes can be broken down into a series of  individual sequential chemical reactions, each controlled by a single gene,  and that mutation of a single gene changes the cell�s ability to carry out  only a single chemical reaction. Each gene was found to determine the  structure of a specific enzyme (the �one gene, one enzyme� hypothesis).  With Joshua Lederberg, Tatum discovered the occurrence of genetic recom�  bination, or �sex,� between certain bacteria. Largely because of their  efforts, bacteria became the main source of information about genetic  control of biochemical processes in the cell.

As head of a  Baltimore heart clinic (1930-63), she studied �blue babies� (babies whose  heart malformations cause low blood oxygen content) and pioneered use  of fluoroscopy and X rays to pinpoint the defect responsible for each set  of symptoms. The surgical treatment she devised with Alfred Blalock  saved thousands of such infants, and her research spurred development of  other surgical treatments for heart disorders. Her Congenital Malforma�  tions of the Heart (2 vol., 1947) comprehensively described heart defects  and diagnostic tools, techniques, and findings. She also played a key role  in alerting U.S. physicians to the dangers of thalidomide.</p><p>tautog See wrasse</p><p>tautology \to-'ta-b-je\ In logic, a statement that cannot be denied with�  out inconsistency. Thus, �All bachelors are either male or not male� is  held to assert, with regard to anything whatsoever that is a bachelor, that  it is male or it is not male. In the propositional calculus, even complicated  symbolic expressions such as [(A zd B) a (C zd �&#x25A0; B)] zd (C z&gt; �&#x25A0; A) can  be shown to be tautologies by displaying in a truth table every possible  combination of T (true) and F (false) of its arguments A, B, C. A tautol�  ogy can be purely formal (a statement form rather than a statement), and  in some usages only such formal truths are tautologies.</p><p>tautomerism Uo-'ta-mo-.ri-zomX Existence of two or more chemical  compounds that have the same chemical composition but different struc�  tures (isomers) and that convert easily from one to another. A major class  of tautomeric reactions involves exchange of a hydrogen atom between  two other atoms in the same molecule, in both cases forming a covalent  bond. For example, in keto-enol tautomerism, the hydrogen atom bonded  to the carbon atom in a carbonyl (keto) group (�CH�C=0; see func�  tional group) moves to the oxygen atom, making it an enol group  (�C=C�OH). The keto form predominates in many aldehydes and  ketones, the enol form in phenols. Sugars (e.g., glucose) exhibit tautom�  erism between open (chain) forms and closed (ring) forms.

He was educated at  Rugby School and at the University of Oxford, where he wrote his first  major work, The Agrarian Problem in the Sixteenth Century (1912). From  1913 he taught at the London School of Economics. An ardent socialist, he  helped formulate the economic and moral viewpoint of the Labour Party in  the 1920s and �30s. In his most influential book, The Acquisitive Society  (1920), he argued that the acquisitiveness of capitalist society was a mor�  ally wrong motivating principle. His Religion and the Rise of Capitalism  (1926), which built on the work of Max Weber, also became a classic.</p><p>tax Government levy on persons, groups, or businesses. Taxes are a gen�  eral obligation of taxpayers and are not paid in exchange for any specific  benefit. They have existed since ancient times� property TAxes and sales  taxes were known in ancient Rome�but tariffs were favoured over inter�  nal taxes as a source of revenue. In modem economies, there has been a  trend away from tariffs in favour of internal taxes, which provide the</p><p>majority of revenues. Taxes have three functions: to cover government  spending, to promote stable economic growth, and to lessen inequalities  in the distribution of income and wealth. They have also been used for  nonfiscal reasons, such as to encourage or discourage certain activities  (e.g., cigarette consumption). Taxes may be classified as direct or indi�  rect. Direct taxes are those that the taxpayer cannot shift onto someone  else; they are mainly taxes on persons and are based on an individual�s  ability to pay as measured by income or net wealth. Direct taxes include  income TAxes, taxes on net worth, death duties (i.e., inheritance and estate  taxes), and gift taxes. Indirect taxes are those that can be shifted in whole  or in part to someone other than the person legally responsible for pay�  ment. These include excise taxes, sales taxes, and value-added TAxes. Taxes  may also be classified according to the effect they have on the distribu�  tion of wealth. A proportional tax is one that imposes the same relative  burden on all taxpayers, unlike progressive TAxes and regressive taxes.</p><p>Taxco \'tas-ko\ in full Taxco de Alarcon Town (pop., 2000: 50,488),  Guerrero state, south-central Mexico.

Because of its colonial character, with its cobblestone streets  and the baroque Church of Santa Prisca, it has been declared a national  landmark.</p><p>taxidermy Practice of creating lifelike representations of animals by  using their prepared skins and various supporting structures. Taxidermy  began with the ancient custom of keeping trophies of the hunt. Beginning  in the 18th century, a growing interest in natural history resulted in col�  lections and exhibits of birds, beasts, and curiosities. Chemically preserv�  ing skins, hair, and feathers made it possible to recreate the appearance  of live animals by stuffing the sewed-up skin with straw or hay. Con�  structing and sculpting anatomically correct manikins of clay and plaster  are the basis of modem taxidermy.</p><p>Taxila \'tak-so-b\ Ancient city, northwestern Pakistan. Its ruins, includ�  ing temples and a fortress, lie just northwest of Rawalpindi. It was the  capital of the Buddhist kingdom of Gandhara and a centre of learning.  Founded by Bharata, the younger brother of Rama, it came under Persian  rule and in 326 bc was surrendered to Alexander the Great. Ruled by a  succession of conquerors, including Bactrians and Scythians, the city  became an important Buddhist centre under King Ashoka (c. 261 bc). The  apostle Thomas reputedly visited it in the 1st century ad. Taxila� s pros�  perity in ancient times resulted from its position at the junction of three  great trade routes. When they declined, the city sank into insignificance;  it was finally destroyed by the Huns in the 5th century.</p><p>taxol \'taks-ol\ Organic compound with a complex multi-ring molecule  that occurs in the bark of Pacific yew trees ( Taxus brevifolia). It is active  against certain cancers of the lung, ovary, breast, head, and neck, disrupt�  ing cell division and interfering with separation of the nuclear chromo�  somes. A semisynthetic process to make it from yew needles and twigs  eliminated the prospect of widespread destruction of yew forests, and total  synthesis methods were later developed.</p><p>taxonomy \tak-'sa-n3-me\ In biology, the classification of organisms  into a hierarchy of groupings, from the general to the particular, that reflect  evolutionary and usually morphological relationships: kingdom, phylum,  class, order, family, genus, species. The black-capped chickadee, for  example, is an animal (kingdom Animalia) with a dorsal nerve cord (phy�  lum Chordata) and feathers (class Aves: birds) that perches (order Passe�  riformes: perching birds) and is small with a short bill (family Paridae),  a song that sounds like �chik-a-dee� (genus Parus ), and a black-capped  head (species atricapillus ). Most authorities recognize five kingdoms:  monerans (prokaryotes), protists, fungi (see fungus), plants, and animals.

She left London for Los Angeles with her Ameri�  can parents at the outset of World War II. Noted for her exceptional beauty  from childhood, she was discovered by a talent scout in Beverly Hills.  She made her screen debut in 1942, appeared in Lassie Come Home in  1943, and became a star with National Velvet in 1944. She was a glam�  orous adult star in A Place in the Sun (1951), Cat on a Hot Tin Roof  (1958), and Butterfield 8 (1960, Academy Award). In Who�s Afraid of Vir�  ginia Woolf (1966, Academy Award) and other films, she starred opposite  her husband, Richard Burton. After the mid-1970s, she appeared only  intermittently in films, Broadway plays, and television films. Taylor�s  personal life (she was married eight times) was exceptionally well pub�  licized and often tended to overshadow her acting career.</p><p>Taylor, Frederick W(inslow) (b. March 20, 1856, Philadelphia, Pa.,  U.S.�d. March 21, 1915, Philadelphia) U.S. inventor and engineer. He  worked at Midvale Steel Co. (1878-90), where he introduced time-and-  motion study in order to systematize shop management and reduce manu�  facturing costs. Though his system provoked resentment and opposition  from labour when carried to extremes, it had an immense impact on the  development of mass production techniques and has influenced the devel�  opment of virtually every modern industrial country. Taylor is regarded  as the father of scientific management. See also production management;  Taylorism.</p><p>Taylor, Sir Geoffrey Ingram (b. March 7, 1886, London, Eng.�d.  June 27, 1975, Cambridge) British physicist. He taught at Cambridge Uni�  versity from 1911 to 1952. He made important discoveries in fluid mechan�  ics, as well as significant contributions to the theory of the elastostatic stress  and displacement fields created by dislocating solids, the quantum theory  of radiation, and the interference and diffraction of photons.</p><p>Taylor, John known as John Taylor of Caroline (b. Dec. 19?,  1753, Caroline county, Va.�d. Aug. 21, 1824, Caroline county, Va., U.S.)  U.S. politician. He served in the Continental Army (1775-79) and the  Virginia militia (1781) in the American Revolution. A strong advocate of  states' rights, he opposed ratification of the U.S. Constitution. He was a  member of the U.S. Senate (1792-94, 1803, 1822-24), and he introduced  the Virginia and Kentucky Resolutions in the Virginia legislature (1798). A  supporter of Thomas Jefferson, he wrote essays on the importance of main�  taining an agrarian democracy as a defense against the development of  an overly powerful central government.</p><p>Taylor, Joseph H(ooton), Jr. (b. March 24, 1941, Philadelphia, Pa.,  U.S.) U.S. physicist. He received his Ph.D. from Harvard University.  While teaching at the University of Massachusetts (1968-81), he and  Russell Alan Hulse discovered the first binary pulsar (1974). Their discov�  ery provided evidence in support of Albert Einstein�s relativistic theory of  gravitation, which predicts that objects accelerated in a strong gravita�  tional field will emit gravitational waves. With its enormous interacting  gravitational fields, the binary pulsar should emit such waves, draining  energy and reducing the orbital distance between the two stars. In 1978  they showed, on the basis of tiny variations in the pulsar�s radio emission,  that the two stars are revolving ever faster and closer around each other  at a rate agreeing precisely with Einstein�s prediction. Their discoveries  won the two men a 1993 Nobel Prize.</p><p>Taylor, Lawrence (Julius) (b. Feb. 4, 1959, Williamsburg, Va., U.S.)  U.S. football linebacker. He played for the University of North Carolina,  making All-American in 1980. During his 13-year career with the New  York Giants (1981-94), he was twice named Defensive Player of the Year  (1981, 1982) and once named Most Valuable Player (1986), only the sec�  ond defensive player to be so honoured. The prototypical linebacker of  his era, he possessed the strength to defeat blocks from linemen and the  speed to chase down running backs.</p><p>Taylor, Maxwell (Davenport) (b.

He gradu�  ated from West Point and helped organize the army�s first airborne divi�  sion early in World War II. He commanded a parachute assault in the  Normandy Campaign and in the Battle of the Bulge (1944). He served as</p><p>commanding general of UN forces in Korea (1953), as U.S. Army chief  of staff (1955-59), and as chairman of the Joint Chiefs of Staff (1962-  64).

He advocated  the maintenance of conventional infantry as a prudent alternative to the  use of nuclear weapons in war.</p><p>Taylor, Paul (Belville) (b. July 29, 1930, Wilkinsburg, Pa., U.S.) U.S.  modern dancer, choreographer, and  director. In 1953 he joined Martha  Graham�s company, where he was a  leading soloist until 1960. In 1957 he  established the Paul Taylor Dance  Company. As a choreographer he  employed a wide variety of move�  ment styles, some of which he  described as �flat� (two-dimensional  in appearance), �dance scribbling�</p><p>(emphasis on action rather than on  shape or line), and �lyric� (�long  arms�). His works include Duet  (1957), Aureole (1962), Orbs (1966),  and Nightshade (1979).

U.S. short-story writer, novelist, and playwright. Taylor stud�  ied in the 1930s under several poets associated with the Southern literary  renaissance. He taught at various schools, including the University of Vir�  ginia. He is best known for his short stories, which are usually set in con�  temporary Tennessee and which reveal conflicts between the old rural  society and the industrialized �New South.� The novella A Woman of  Means (1950) is perhaps his finest work; his later works include The Old  Forest and Other Stories (1985) and A Summons to Memphis (1986,  Pulitzer Prize).</p><p>Taylor, Zachary (b. Nov. 24, 1784, Montebello, Va., U.S.�d. July 9,  1850, Washington, D.C.) 12th president of the U.S. (1849-50). He fought  in the War of 1812, the Black Hawk War (1832), and the Seminole War  in Florida (1835�42), earning the nickname �Old Rough-and-Ready� for  his indifference to hardship. Sent to Texas in anticipation of war with  Mexico, he defeated the Mexican invaders at the battles of Palo Alto and  Resaca de la Palma (1846). After the Mexican War formally began, he  captured Monterrey and granted the Mexican army an eight-week armi�  stice. Displeased, Pres. James K. Polk transferred Taylor�s best troops to  the command of Winfield Scott to serve in the invasion of Veracruz. Tay�  lor ignored orders to remain in Monterrey and marched south to defeat a  large Mexican force at the Battle of Buena Vista (1847). He became a  national hero and was nominated as the Whig candidate for president  (1848). He defeated Lewis Cass to win the election. His brief term was  marked by a controversy over the new territories that produced the Com�  promise of 1 850 and by a scandal involving members of his cabinet. He  died, probably of cholera, after only 16 months in office and was suc�  ceeded by Millard Fillmore.</p><p>Taylorism System of scientific management advocated by Fred W. Tay�  lor. In Taylor�s view, the task of factory management was to determine  the best way for the worker to do the job, to provide the proper tools and  training, and to provide incentives for good performance. He broke each  job down into its individual motions, analyzed these to determine which  were essential, and timed the workers with a stopwatch. With unneces�  sary motion eliminated, the worker, following a machinelike routine,  became far more productive.

Sensitive and interested in music from his early childhood, Tchai�  kovsky turned to serious composition at age 14. In 1862 he began studying  at the new St. Petersburg Conservatory; from 1866 he taught at the Mos�  cow Conservatory. His Piano Concerto No. 1 (1875) was premiered in  Boston and became immensely popular. He wrote his first ballet. Swan  Lake (first performed 1877), on commission from the Bolshoi Ballet. In  1877 he received a commission from the wealthy Nadezhda von Meek  (1831-94), who became his patron and longtime correspondent. The opera  Eugene Onegin (1878) soon followed. Though homosexual, he married  briefly; after three disastrous months of marriage, he attempted suicide.  His composition was overshadowed by his personal crisis for years. His  second ballet, Sleeping Beauty (1889), was followed by the opera The  Queen of Spades (1890) and the great ballet The Nutcracker (1892). The  Pathetique Symphony (1893) premiered four days before his death from  cholera; claims that he was forced to commit suicide by noblemen out�  raged by his sexual liaisons are unfounded. He revolutionized the ballet  genre by transforming it from a grand decorative gesture into a staged  musical drama. His music has always had great popular appeal because  of its tuneful, poignant melodies, impressive harmonies, and colourful,  picturesque orchestration.</p><p>TCP/IP in full Transmission Control Protocol/Internet Pro�  tocol Standard Internet communications protocols that allow digital com�  puters to communicate over long distances.

Tea cul�  tivation is first documented in China in ad 350; according to legend, it  had been known there since c. 2700 bc. It was established in Japan by the  13th century and was spread to Java by the Dutch and to India by the  English in the 19th century. Today tea is the most widely consumed drink  in the world, drunk (either hot or cold) by half the world�s population.  Major tea types are classified by processing method: fermented, or black,  tea produces an amber-colored, full-flavored beverage without bitterness;  semifermented, or oolong, tea yields a slightly bitter, light brownish-green  liquid; and unfermented, or green, tea, results in a mild, slightly bitter,  pale greenish-yellow beverage. Caffeine is responsible for tea�s stimulat�  ing effect. Green tea, long regarded as healthful in the Far East, has in</p><p>recent years attracted much favorable attention in the West for a wide  range of possible beneficial effects. Infusions and decoctions of the leaves,  bark, and roots of many other, unrelated plants are commonly drunk as  herbal or medicinal teas.</p><p>Tea Act (1773) British legislation giving a tea monopoly in the Ameri�  can colonies to the British East India Co.

It involves a host and one or  more guests; the tea, utensils, and movements used in preparing, serving,  and drinking the tea are all prescribed. When tea was introduced from  Song-dynasty China by the Zen monk Eisai (1141-1215), it was drunk  by Zen monks to help them stay awake during meditation. The laity  enjoyed tea-tasting competitions that developed into a more refined, medi�  tative form among the warrior aristocracy in the 15th century. The most  famous exponent of the tea ceremony was Sen Rikyu (1522-91), tea mas�  ter to Toyotomi Hideyoshi, who codified a style known as wabi, which  favoured rustic, rough-shaped tea bowls and spare, simple surroundings.  Three popular schools of the tea ceremony trace their roots to Rikyu, and  other schools exist as well; today mastery of the tea ceremony is one  accomplishment of a well-bred young woman.</p><p>Teach, Edward See Blackbeard</p><p>teaching Profession of those who give instruction, especially in an  elementary or secondary school or a university. The teaching profession  is a relatively new one. Traditionally, parents, elders, religious leaders,  and sages were responsible for teaching children how to behave and think  and what to believe. Germany introduced the first formal criteria for the  education of teachers in the 18th century. In the 19th century, as society  became more industrialized, the concept of schooling became more uni�  versal. In industrialized nations today, most teachers are university gradu�  ates. Teacher-training programs usually include both general and  specialized academic, cultural, or vocational courses; the study of educa�  tional principles; and a series of professional courses combined with prac�  tical experience in a typical school setting. Most countries also require  professional certification following formal training. See also National  Education Association.</p><p>Teagarden, Jack orig. Weldon Leo Teagarden (b.

It was formed in 1903 with the merger of two team-drivers� unions, and  local deliverymen using horse-drawn vehicles remained the core mem�  bership until the 1930s, when intercity truck drivers became predominant.  From 1907 to 1952 the union was headed by Daniel J. Tobin, who built  it up from 40,000 members in 1907 to more than one million in 1950.  Disclosures of corruption in the leadership led to the Teamsters� expul�  sion from the AFL-CIO in 1957. Between 1957 and 1988 three Teamsters  presidents�Dave Beck, Jimmy Hoffa, and Roy Williams�were convicted  of various criminal charges and sentenced to prison terms. (Hoffa has been  missing, and presumed dead, since 1975.) While Teamsters representa�  tion of truck drivers declined with the growth of nonunion trucking com�  panies in the 1980s, the union gained new members in clerical, service,  and technology occupations. The union was readmitted to the AFL-CIO  in 1987. Presidents Ron Carey (1992-99) and James P.

It is situated on the southern slopes of the Elburz Mountains. It  was originally a suburb of ancient Rhagae (Rey), which was destroyed by  the Mongols in 1220 and was later the home of several Safavid rulers of  Persia (16th-18th centuries). It became prominent after its capture by  Agha Muhammad Khan, founder of the Qajar dynasty, who made it his  capital in 1785. It underwent rapid modernization after 1925 and espe�  cially after World War II (1939-45). In 1943 it was the site of the Tehran  Conference. In 1979, following the Islamic revolution in Iran, the U.S.  embassy there was seized and its staff taken hostage by Iranian militants  (see Iran hostage crisis).

In 1929 he directed the  excavations at the Peking man site at  Zhoukoudian. This and other geologi�  cal work won him high honours,  though it came to be disapproved of  by the Jesuit order. His philosophy  was strongly informed by his scien�  tific work, which he believed helped  prove the existence of God. He is  known for his theory that mankind is  evolving, mentally and socially,  toward a final spiritual unity that he  called the Omega point. Though his  major philosophical works.

The daughter of an Algon�  quin Christian mother and a non-Christian Mohawk father, she was born  in what is now Auriesville, N.Y., U.S., and was partially blinded by small�  pox as a child. She was deeply impressed by the lives and words of three  Jesuit missionaries she met at age 11, and at 20 she was baptized. Harassed  and threatened with torture in her home village, she fled 200 mi (320 km)  to a Christian Indian mission near Montreal, where she became known as  the �Lily of the Mohawks� for her kindness, faith, and heroic suffering  before her early death. She was beatified in 1980.</p><p>tektite Any of a class of small, natural glassy objects found on the  Earth�s surface and associated with meteorite impacts. The extremely high  temperatures and enormous pressures generated when a large meteorite,  comet, or asteroid hits the Earth melt the rocks at the site, producing  masses of molten droplets that are blasted into and out of the Earth�s  atmosphere. The droplets cool quickly to a glassy form and then fall back  to the Earth.</p><p>Tel Aviv-Yafo Vel-o-'vev-'ya-foV or Tel Aviv-Jaffa</p><p>N.tel-o-'vev-'ja-foX City (pop., 1999 est.: 348,100) and main port of Israel.  The hub of Israel�s largest urban centre, it was formed in 1950 by the  incorporation of the ancient port of Jaffa with Tel Aviv, its former sub�  urb. Tel Aviv was founded in 1909 and was the capital of Israel (1948-  50). It grew with Jewish immigration in the early 20th century and by  1936 was the largest and most important city in Palestine. Jaffa was an  old Canaanite city that was taken by Egypt in the 15th century bc and  occupied by the Israelite kings David and Solomon. Over the centuries it  was ruled by the Ptolemies, Syrians, and Romans, captured by the Cru�  saders, and razed by the Mamluks. The British occupied it in 1917; it  surrendered to Jewish military forces during the first Arab-Israeli war  (1948). Israel�s main business, communications, and cultural centre, it is  the site of more than half of Israel�s industrial plants, the country�s stock  exchange, Tel Aviv University (1953), and Bar-Ilan University (1953).</p><p>telecommunications Communication between parties at a distance  from one another. Modem telecommunication systems�capable of trans�  mitting telephone, fax, data, radio, or television signals�can transmit large  volumes of information over long distances. Digital transmission is  employed in order to achieve high reliability with minimal noise, or inter�  ference, and because it can transmit any signal type, digital or analog. For  digital transmission, analog signals must be subjected to a process of  analog-to-digital conversion; most television, radio, and voice communi�  cations are analog and must be digitized before transmission.

In 1921, however, he withdrew from party politics. He then taught at  Budapest University before returning to office as minister of education  (1938-39) and premier (1939�41). Hoping to use Germany�s power to  win back territories lost through the Treaty of Trianon (1920), he initially  cooperated with Adolf Hitler.

By  age 10 he had learned several instruments, and he composed an opera at  age 12, but his family discouraged his pursuit of a musical profession.  While studying law at Leipzig University, he organized student music  groups and became music director of the Leipzig Opera (1702), organist  at the New Church (1704), and kapellmeister to a count (1705). Moving  to Eisenach (c. 1708), where he met Johann Sebastian Bach, he composed  French-style instrumental music and German-style sacred music. He  moved to Gotha (1717) and then Hamburg (1721), where he served as  musical director of the Opera (1722-38), for which he wrote several dozen  Italian-influenced works. He wrote some 600 cantatas and a total of some  2,000 pieces, many of high quality.</p><p>telemetry \t3-Te-mo-tre\ Highly automated communications process by  which data are collected from instruments located at remote or inaccessible  points and transmitted to receiving equipment for measurement, monitor�  ing, display, and recording. Transmission of the information may be over  wires or, more commonly, by radio. The technique is used extensively for  oil-pipeline monitoring and control systems and in oceanography and  meteorology. Telemetry for rockets and satellites bloomed in the 1950s and  has continued to grow in complexity and in breadth of application. Data can  be transmitted from inside internal-combustion engines during tests, from  steam turbines in operation, and from manned and unmanned spacecraft.  Major scientific applications include biomedical research and remote  observation of operations with highly radioactive material.</p><p>teleological argument See argument from design</p><p>teleological ethics Theory that derives duty from what is valuable as  an end, in a manner diametrically opposed to deontological ethics. Teleo�  logical ethics holds that the basic standard of duty is the contribution that  an action makes to the realization of nonmoral values. Teleological theo�  ries differ on the nature of the nonmoral goods that actions ought to pro�  mote. Eudaemonism emphasizes the cultivation of virtue in the agent as the  end of all action. Utilitarianism holds that the end consists in the aggregate  balance of pleasure to pain for all concerned. Other teleological theories  claim that the end of action is survival and growth, as in evolutionary  ethics (Herbert Spencer); power over others (Niccolo Machiavelu and  Friedrich Nietzsche); satisfaction and adjustment, as in pragmatism (Ralph  Barton Perry and John Dewey); and freedom, as in existentialism (Jean-Paul  Sartre).</p><p>teleology \,te-le-'a-b-je\ Causality in which the effect is explained by  an end (Greek, telos ) to be realized. Teleology thus differs essentially from  efficient causality, in which an effect is dependent on prior events. Aris�  totle�s account of teleology declared that a full explanation of anything  must consider its final cause�the purpose for which the thing exists or  was produced. Following Aristotle, many philosophers have conceived of  biological processes as involving the operation of a guiding end. Modem  science has tended to appeal only to efficient causes in its investigations.  See also mechanism.</p><p>telephone Instrument designed for simultaneous transmission and  reception of the human voice. It works by converting the sound waves of  the human voice to pulses of electrical current, transmitting the current,  and then retranslating the current back to sound. The U.S. patent granted  to Alexander Graham Bell in 1876 for developing a device to transmit  speech sounds over electric wires is often called the most valuable ever  issued. Within 20 years, the telephone acquired a form that has remained  fundamentally unchanged for more than a century. The advent of the  transistor (1947) led to lightweight, compact circuitry (see cell phone).  Advances in electronics have allowed the introduction of a number of  �smart� features such as automatic redialing, caller identification, call  waiting, and call forwarding. Telephone systems are also a primary access  route for the Internet.</p><p>telescope Device that collects light from and magnifies images of dis�  tant objects, undoubtedly the most important investigative tool in  astronomy. The first telescopes focused visible light by refraction through  LENSes; later instruments used reflection from curved mirrors (see optics).  Their invention is traditionally credited to Hans Lippershey (15707-  lb 19?), who adapted A. van Leeuwenhoek�s use of lenses in microscopes.  Among the earliest telescopes were Galilean telescopes, modeled after the  simple instruments built by Galileo, who was the first to use telescopes  to study celestial bodies. In 1611 Johannes Kepler proposed an improved  version that became the basis for modem refracting instruments. The  reflecting telescope came into its own after William Herschel (see Her-  schel family) used one to discover the planet Uranus in 1781. Since the  1930s radio telescopes have been used to detect and form images from  radio waves emitted by celestial objects. More recently, telescopes have  been designed to observe objects and phenomena in other parts of the  ELECTROMAGNETIC SPECTRUM (see GAMMA-RAY ASTRONOMY; INFRARED ASTRONOMY;</p><p>ultraviolet astronomy; X-ray astronomy).

Early versions (1900-20) of the  cathode-ray (picture) tube, methods of amplifying an electronic signal, and  theoretical formulation of the electronic-scanning principle later became  the basis of modem TV. RCA demonstrated the first all-electronic TV in  1932. Colour TV (in the 1950s), cable TV systems (introduced in the 1960s),  and recording or playback machines (in the 1980s; see VCR) followed.

In 1941 he joined Enrico Fer�  mi�s team in the effort to produce the  first self-sustaining nuclear reaction,  and in 1943 J. Robert Oppenheimer  recruited him for the Manhattan  Project. At the war�s end, Teller  advocated development of a fusion  bomb, and he won permission after  initial government resistance. With  Stanislaw Ulam he developed a work�  able hydrogen bomb in 1952. That  same year he helped establish the  Lawrence Livermore Laboratory  (Livermore, Calif.), which became  the chief U.S. factory for nuclear weapons. In 1954 he joined the oppo�  sition to Oppenheimer�s continued security clearance. A staunch anticom�</p><p>munist, he devoted much energy to his crusade to keep the U.S. ahead of  the Soviet Union in nuclear arms; he opposed nuclear weapons treaties,  and he was principally responsible for convincing Pres.

The Pin-  ios River flows through the 6-mi (10-km) valley before emptying into the  Aegean Sea. The ancient Greeks dedicated Tempe to the cult of Apollo.  Legends attribute its formation to a blow from Poseidon�s trident; how�  ever, geologists believe it was carved by stream action.

Heat flows from  a hotter body to a colder one and continues to do so until both are at the  same temperature. Temperature is a measure of the average energy of the  molecules of a body, whereas heat is a measure of the total amount of  thermal energy in a body. For example, whereas the temperature of a cup  of boiling water is the same as that of a large pot of boiling water (212�F,</p><p>Edward Teller.</p><p>COURTESY OF THE UNIVERSITY OF CALIFORNIA LAWRENCE  BERKELEY LABORATORY, BERKELEY, CAUF.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>temperature inversion &#x25BA; Tempyo style I 1885</p><p>or 100�C), the large pot has more heat, or thermal energy, and it takes  more energy to boil a pot of water than a cup of water. The most com�  mon temperature scales are based on arbitrarily defined fixed points. The  Fahrenheit scale sets 32� as the freezing point of water and 212� as the  boiling point of water (at standard atmospheric pressure). The Celsius  scale defines the triple point of water (at which all three phases, solid,  liquid, and gas, coexist in equilibrium) at 0.01� and the boiling point at  100�. The Kelvin scale, used primarily for scientific and engineering pur�  poses, sets the zero point at absolute zero and uses a degree the same size  as those of the Celsius scale.</p><p>temperature inversion In meteorology, an increase of air tempera�  ture with altitude. Such an increase is a reversal of the normal tempera�  ture condition of the troposphere, where temperature usually decreases  with altitude. Inversions play an important role in determining cloud  forms, precipitation, and visibility. An inversion acts as a lid, preventing  the upward movement of the air below it. Where a pronounced inversion  is present at a low level, convective clouds cannot grow high enough to  produce showers and, at the same time, visibility may be greatly reduced  by trapped pollutants (see smog). Because the air near the base of the  inversion is cool, fog is frequently present there.</p><p>tempering Heat-treating of metal alloys, particularly steel, to reduce  brittleness and restore ductility. In tempering, steel is slowly heated to a  temperature between 300 and 1,300 �F (150 and 700 �C), depending on  desired properties, in an oil or salt bath and held for about two hours and  then allowed to air cool. As steel is physically worked (e.g., rolling, wire�  drawing, hammering), hardening takes place, and it grows progressively  more brittle. Similarly, but more deliberately, heating and quenching  increase hardness. Combined quench-and-temper heat-treating is applied  at many different cooling rates, holding times, and temperatures and is a  very important means of controlling the properties of steel.</p><p>Tempest, Dame Marie orig.

At its beginning  (c. 1119), the group consisted of eight or nine French knights who devoted  themselves to protecting from Muslim warriors those on pilgrimage to  Jerusalem. They were given quarters near the site of the former Temple of  Jerusalem, from which they derived their name. Taking vows of poverty  and chastity, they performed courageous service, and their numbers  increased rapidly, partly because of the propagandistic writing of St. Ber�  nard de Clairvaux, who also wrote their rule of life. They flourished for  two centuries, expanding to other countries, growing in number to 20,000,  and acquiring vast wealth and property. By 1304 rumours, probably false,  of irreligious practices and blasphemies had made them the target of per�  secution. In 1307 Philip IV of France and Pope Clement V initiated the  offensive that culminated in the Templars� final suppression in 1312,  including the confiscation of all their property and the imprisonment or  execution of many members; their last leader, Jacques de Molay (1243-  1314), was burned at the stake.</p><p>temple Edifice constructed for the worship of a deity. Features commonly  include a sanctuary and an altar. Ancient Egypt had two kinds of temple:  mortuary temples for the cults of dead kings, with a chapel in which offer�  ings were presented, and cult temples that held images of deities. The cult  temple typically included a massive pylon entrance with a court leading to  a hypostyle hall and, at the heart of the temple, a shrine for the cult image.  Most Classical Greek temples were rectangular and built of marble or other  stone on a low stylobate (stepped platform). A gable roof was supported by  columns, with a portico at each end (amphiprostyle temple), a colonnade  extending all around (peripteral temple), or a double line of columns all  around (dipteral temple). An inner cella housed the image of a deity, and an</p><p>altar stood outside the temple. Roman temples were profoundly influenced  by Greek style, but the altar was inside the temple and the colonnade was  often reduced to a row of engaged columns. Hindu temples vary regionally,  but generally consist of a towering shrine and a columned hall surrounded  by an elaborate wall. Buddhist temples range from half-buried sanctuaries  with richly carved entrances to single carved towers or statues. The Chi�  nese and Japanese Buddhist temple is typically a one-story building of  richly carved, painted, or tiled timber constructed around an atrium used  for worship, though towering pagodas were sometimes built as temples  over a shrine. In the Americas, Inca and Mayan temples were constructed  of stone, often richly carved; they were generally stair-stepped pyramids,  with the shrine at the top.

As ambassador to The Hague  (1668-70, 1674-79), he formulated England�s pro-Dutch foreign policy  and arranged the marriage between William of Orange and Princess Mary  of England (later William III and Mary II). After retiring from politics in  1681, he wrote numerous essays that were collected for publication by his  secretary, Jonathan Swift. He also wrote the acclaimed Observations upon  the United Provinces (1673).</p><p>Temple of Heaven Large religious complex in the old outer city of  Beijing, considered the supreme achievement of traditional Chinese archi�  tecture. Its layout symbolizes the  belief that heaven is round and earth  square. The three buildings are built  in a straight line. The Hall of Prayer  for Good Harvests (1420) has three  concentric circles of massive wood  columns symbolizing the four sea�  sons, 12 months, and 12 daily hours;  in a remarkable feat of engineering,  they support the three roof levels  and, in succession, a huge square  brace (earth), circular architrave  (heaven), and vast interior cupola.</p><p>The Imperial Vault of Heaven (1530;  rebuilt 1572) is a smaller circular  building constructed without cross�  beams; its dome is supported by  complicated span work.

Most  scholars propose a date between the 16th and 13th century bc for the com�  mandments, though some date them as late as 750 bc. They were not  regarded with deep reverence by Christians until the 13th century.</p><p>Ten Thousand Smokes, Valley of Volcanic region, southern  Alaska, U.S. Located in Katmai National Park and Preserve, the valley cov�  ers 56 sq mi (145 sq km). It was created in 1912 when the eruption of  the Novarupta and Mount Katmai volcanoes covered the valley in a flow  of lava. When an expedition visited the site in 1916, it discovered tens of  thousands of fissures known as fumaroles spouting smoke, gas, and steam  in the valley floor. The largest was 150 ft (46 m) in diameter; some had  temperatures as high as 1,200 �F (649 �C). About 60 years later there were  fewer than 12 fumaroles left. In the 1960s U.S. astronauts used the scarred  region to train for Moon landings.</p><p>tenant See landlord and tenant</p><p>tenant farming Agricultural system in which landowners rent their  land to farmers and receive either cash or a share of the product in return.  Landowners may also contribute operating capital and management.  Under one arrangement, known as sharecropping, the landowner furnishes  all the capital and sometimes the food, clothing, and medical expenses of  the tenant and may also supervise the work. The sharecropper then pays  the landowner with a portion of the output grown on the land. In other  forms of tenant farming, the tenant may furnish all the equipment and  have substantial autonomy in the farm�s operation. Tenants and their fami�  lies probably constitute two-fifths of the world�s population engaged in  agriculture. Tenant farming can be highly efficient, as has been shown in  England and Wales. Abuses occur when landowners� power is excessive  and the tenants are poor or of inferior social status.</p><p>Tendai See Tiantai</p><p>tendinitis or tendonitis \,ten-d 3 n-T-t9s\ Inflammation of a tendon  sheath, due to irritation of this thin, filmy tissue by overuse of the ten�  dons, which slide within them, or to bacterial infection. It is often an  occupational disease, affecting tendons used in repetitive motions on the  job. The tendon becomes swollen and red, with pain that increases on  motion. The swelling hampers the tendon�s sliding within, causing stiff�  ness. Treatment involves immobilization with a splint, cast, or bandage  and gradually increasing motion after inflammation subsides, which may  happen sooner with corticosteroid injections. Repeated episodes can per�  manently thicken the sheath, limiting motion.</p><p>tendon Tissue attaching a muscle to other body parts, usually bones, to  transmit the mechanical force of muscle contraction to the other part.  Much like ligaments, tendons are composed of dense, fibrous connective  tissue with a high collagen content, which makes them remarkably tough  and strong, with great tensile strength to withstand the stresses generated  by muscle contraction.</p><p>tendril Plant organ specialized to anchor and support vining stems. A  tendril is a slender, whiplike or threadlike strand, produced usually from  the node of a stem and composed of either stem or leafstalk tissue, by  which a vine or other plant may climb. Sensitive to contact, the tendril  turns toward any object it brushes against, wraps about it, and clings to it  for as long as the stimulation persists. Later, strong mechanical tissue  develops in the tendrils, making them strong enough to support the weight  of the plant. Some tendrils have enlargements at the ends that flatten and  produce an adhesive that firmly cements them to their support. Common  examples of tendril plants are grape, English ivy, sweet pea, gourds, and  PASSIONFLOWERS.</p><p>Tenerife, Pico de See Pico de Teide  Teng Hsiao-p'ing See Deng Xiaoping</p><p>Teniers Uo-'nirs, ta-'nya\, David (baptized Dec. 15, 1610, Antwerp,  Belg.�d.

The younger Teniers was highly prolific and is best known for  his genre scenes of peasant life, many of which were used for tapestry  designs in the 18th century. He was brilliant at handling crowd scenes in  an open landscape and adept at characterizing his figures with a warm,  human, and often humorous touch. As court painter to the archduke  Leopold William, he also made many small-scale copies of paintings in  the archduke�s collection; engraved and published as Theatrum Pictorium  (1660), they constitute a valuable source as a pictorial inventory of a great  17th-century collection.</p><p>Tennessee State (pop., 2000: 5,689,283), southeast-central U.S. It occu�  pies 42,144 sq mi (109,153 sq km); its capital is Nashville. It is bordered  by Kentucky and Virginia to the north, North Carolina to the east, Ala�  bama and Mississippi to the south, and Arkansas and Missouri to the west.  The Great Smoky Mountains edge the eastern part of the state, while the  Mississippi River is on its western boundary. The Tennessee River valley domi�  nates much of the state, and the Tennessee Valley Authority is the nation�s  largest electric-power generating system. Tennessee has a moderate cli�  mate; about half of it is forested. American Indians, including Chickasaw,  Cherokee, and Shawnee, inhabited the region when Spanish, French, and  English explorers visited it in the 16th-17th centuries. It was included in  the British charter of Carolina and in the French Louisiana claim and was  ceded to Great Britain after the French and Indian War. The first perma�  nent settlement was made c. 1770. It was part of North Carolina until  1785, when the area�s settlers broke away and formed the free state of  Franklin. North Carolina relinquished its claim in 1789, and Tennessee  became the 16th U.S. state in 1796. In 1861 it seceded from the Union;  the hard-fought American Civil War battles of Shiloh, Chattanooga, Stones  River, and Nashville occurred there. In 1866 it was the first state read�  mitted to the Union. During the Reconstruction era, blacks lost what little  power they had gained. After World War II Tennessee became a testing  ground for those involved in the civil rights movement. The state�s economy  is based on manufacturing.</p><p>Tennessee River Navigable river, Tennessee, northern Alabama, and  western Kentucky, U.S. Formed by the confluence of the Holston and  French Broad rivers in eastern Tennessee, it flows 652 mi (1,049 km)  before joining the Ohio River in Kentucky. During the American Civil War  it served as a strategic invasion route into the western Confederacy. Its  development as one of the world�s greatest irrigation and hydropower  systems began with the establishment in 1933 of the Tennessee Valley  Authority. The Tennessee River is linked to the Tombigbee River by the  Tennessee-Tombigbee Waterway.</p><p>Tennessee Valley Authority (TVA) U.S. government agency estab�  lished in 1933 to control floods, improve navigation, and generate elec�  trical power along the Tennessee River and its tributaries. The TVA is a  public corporation governed by a board of directors. It has jurisdiction  over the entire basin of the river, which covers parts of seven states: Ala�  bama, Georgia, Kentucky, Mississippi, North Carolina, Tennessee, and  Virginia. Created by Congress as one of the major public-works projects  of the New Deal, the TVA built a system of dams to control the region�s  chronic flooding, deepened the channel to improve navigation, and  encouraged the development of port facilities along the river. The projects  greatly increased traffic on the river and provided cheap electricity, spur�  ring the industrial development of what had been a chronically depressed  regional economy.

It was developed for touring U.S. Southern plantations. It averages 15.2  hands (61 in. [154 cm]) high and weighs about 1,000 lb (450 kg). Coat  colour varies. Its ancestors included any horse capable of a running walk,  a natural gait that cannot be acquired, but the most influential stallion was  a Standardbred. The running walk, faster than a flat-footed walk, is a low,  gliding, reaching action; the front foot strikes the ground an instant before  the diagonal hind foot, which then oversteps the front footprint by sev�  eral inches.</p><p>Tenniel Vten-yslX, Sir John (b.

A tied score (�deuce�)  requires continued play until a two-  point margin is achieved. The first  player to win six games, with a lead  of two games, takes the set. A match  consists of the best two out of three (or three out of five) sets. Since the  early 1970s, tiebreakers have been employed to eliminate marathon sets.  Tennis developed in the 1870s in Britain from earlier racket-and-ball  games. The first world lawn-tennis championship was held in 1877 at  Wimbledon; clay- and hard-court competitions emerged later. Current  international team tournaments include the Davis Cup for men and the  Federation Cup (since 1963) for women�s teams.

Oct. 6, 1892, Aldworth,  Surrey) English poet, the leading poet of the Victorian age. While attend�  ing Cambridge University, Tennyson developed a deep friendship with  Arthur Hallam. His reputation as a poet increased at Cambridge, and he  published Poems, Chiefly Lyrical (1830). Another volume, including �The  Lotos-Eaters� and �The Lady of Shalott,� was published in 1832 (dated  1833). Hallam�s sudden death in 1833 prompted Tennyson to write poems  that eventually became part of the vast In Memoriam (1850) and lyrics  that later appeared in the brooding Maud (1855), his favourite poem.  Poems (1842), including �Ulysses,� �Morte d�Arthur,� and �Locksley  Hall,� followed, then The Princess (1847), a long antifeminist fantasia  that includes such lyrics as �Sweet and Low� and �Tears, Idle Tears.� In  1850 he married; that year he was also named poet laureate of England.  Among his subsequent works are �The Charge of the Light Brigade�  (1855); Idylls of the King (1859), treating the Arthurian legend; and Enoch  Arden (1864). A consummate poet who was inclined to melancholy, Ten�  nyson was also regarded as a spokesman for the educated English middle  class. His works often dealt with the difficulties of an age when tradi�  tional assumptions were increasingly called into question by science and  modern progress.</p><p>Tenochtitlan \ta-,n6ch-tet-'lan\ Ancient capital of the Aztec empire.

Originally located  on two small islands in Lake Texcoco, it gradually spread through the con�  struction of artificial islands to cover more than 5 sq mi (13 sq km). It was  connected to the mainland by several causeways. The population in 1519  was estimated to be about 400,000 people, the largest residential concen�</p><p>tration in Mesoamerican history.

The daughter of a  grocer, she became a nun and went to India as a young woman. After  studying nursing, she moved to the slums of Calcutta (Kolkata); in 1948  she founded her order, which served the blind, the aged, the disabled, and  the dying. In 1963 the Indian government awarded her the Padmashri  (�Lord of the Lotus�) for her services to the people of India, and in 1971  Pope Paul VI awarded her the first Pope John XXIII Peace Prize. In 1979  she received the Nobel Prize for Peace. Although in her later years she  suffered from a worsening heart condition, Mother Teresa continued to  serve the poor and sick and also spoke out against divorce, contraception,  and abortion. Her order included hundreds of centres in more than 90  countries, with some 4,000 nuns and hundreds of thousands of lay work�  ers. She was succeeded by the Indian-born Sister Nirmala. The process  to declare her a saint began within two years of her death, and Pope John  Paul II issued a special dispensation to expedite the process. She was  beatified on Oct. 19, 2003, reaching the ranks of the blessed in the short�  est time in the church�s history.</p><p>Teresa of Avila, Saint orig. Teresa de Cepeda y Ahumada</p><p>(b. March 28, 1515, Avila, Spain�d. Oct. 4, 1582, Alba de Tormes; can�  onized 1622; feast day October 15) Spanish Carmelite nun, mystic, and  saint. After entering a convent around the age of 20, she fell seriously ill.  She underwent a religious awakening in 1555 and, despite her frail health,  initiated the Carmelite Reform, leading the order�s return to its original  austere practices, including poverty and seclusion from the world. Against  some opposition, she opened new convents (the first in 1562) under the  reformed order throughout Spain. St. John of the Cross joined her in her  efforts, establishing reformed Carmelite monasteries. Her doctrines have  been accepted as the classical exposition of the contemplative life, and  her spiritual writings are still widely read today, among them The Inte�  rior Castle (1588). In 1970 she became the first woman elevated to the  position of Doctor of the Church.</p><p>Tereshkova \ 1 ter-3sh- , ko-v3\, Valentina (Vladimirovna) (b.</p><p>March 6, 1937, Maslennikovo, Russia, U.S.S.R.) Russian cosmonaut. An  accomplished parachutist, she was accepted for the cosmonaut program  in 1961. In 1963 she became the first woman in space, making 48 orbits  in 71 hours aboard Vostok 6. She left the program after her flight and  served in various governmental positions until the early 1990s. She was  named a hero of the Soviet Union and twice awarded the Order of Lenin.</p><p>Terkel Vtor-kolV, Studs orig. Louis Turkel (b. May 16, 1912, New  York, N.Y., U.S.) U.S. radio personality and author. He moved with his  family to Chicago when he was eight. Terkel gave up a legal career to  become a radio disk jockey and interviewer, exposure that led to his own  television show in 1950. In 1953, blacklisted from television for his left�  ist leanings, he returned to radio, continuing at the same station for 45  years. His books include Division Street (1967), about Chicago; Hard  Times (1970), about the Depression; Working (1974), on Americans and  their jobs; The Good War, on World War II (1984, Pulitzer Prize); and  Race (1992), on American feelings about race.</p><p>Terman, Lewis M(adison) (b.

After join�  ing the faculty of Stanford University in 1910, he revised the Binet-Simon  intelligence scale and published the Stanford-Binet IQ test (1916), which  soon was widely adopted in the U.S. During World War I he developed  group intelligence testing for the U.S. Army, and in 1921 he launched a  long-term program for the study of gifted children. He wrote The Mea�  surement of Intelligence (1916) and coauthored Genetic Studies of Genius  (5 vol., 1926-59).</p><p>termite Any of 1,900 species (order Isoptera) of mostly tropical, social,  cellulose-eating insects that are usually soft-bodied and wingless. Intesti�</p><p>nal microorganisms enable them to digest cellulose. Termite colonies con�  sist of a fertile queen and king (reproductives), workers (the most  numerous), and soldiers (see caste). Kings are less than an inch long (1-2  cm), but a queen may grow to more than 4 in. (11 cm). Workers and soldiers  are sterile and blind. They survive two to five years; reproductives may live  for 60-70 years. Termites live in a sealed, humid nest in wood or under�  ground. Underground nests may be built up into a mound. Periodically,  alates (winged, sighted forms) develop and leave the nest to start a new  colony. Termites eat chiefly wood. Soil-dwelling termites attack wood that  is in contact with the ground; wood-dwelling termites, requiring less  humidity than soil-dwellers, attack trees, posts, and wooden buildings.</p><p>tern Any of about 40 species (subfamily Steminae, family Laridae) of  slender, web-footed, migratory water birds found almost worldwide. Spe�  cies vary from 8 to 22 in. (20-55 cm) long. The plumage is white, black-  and-white, or black; the sharply pointed bill is black, red, or yellow; and  the feet are red or black. Most species have long, pointed wings and a  forked tail. Terns plunge into the water to catch crustaceans and fishes.  They breed colonially, usually on the ground on islands. See also Arctic  TERN.</p><p>terneplate Vtom-.pliUA Steel sheet with a coating of terne metal, an alloy  of lead and tin applied by dipping the steel in molten metal. The lead con�  tent gives terneplate a dull appearance, a noncorrosive surface, and sol-  derability. The tin (12-50% of the alloy) wets the steel, making possible  the union of lead and iron, which would otherwise not alloy. While it is  still used for roofing, gutters and downspouts, casket linings, gasoline  tanks, oil cans, and various containers, it has largely been replaced by  other, more durable steel products that are easier to manufacture.

Terra-cotta  objects are usually left unglazed and  are often of a utilitarian kind, because  of their cheapness, versatility, and  durability. Small terra-cotta figures  from 3000 bc have been found in  Greece and others throughout the  Roman Empire from the 4th century  bc. The use of terra-cotta virtually  died out when the Roman Empire  collapsed, but it was revived in Italy  and Germany in the 15th century.</p><p>Terranova Pausania See Olbia</p><p>terrapin Any omnivorous aquatic  turtle of the family Emydidae, espe�  cially the diamondback terrapin  {Malaclemys terrapin). The dia�  mondback inhabits salt marshes and  coasts from New England to the Gulf  of Mexico. It has raised diamond�  shaped patterns on its brownish or  black upper shell. The female attains  a shell length of about 9 in. (23 cm);  the male grows to about 6 in. (14  cm). The eight species of the turtle  genus Pseudemys (or Chrysemys) are  sometimes referred to as terrapins.</p><p>They inhabit freshwaters from the  northeastern U.S. to Argentina.

Bred to fight and kill, they often were pugnacious but are now bred for a  friendlier temperament. Because terriers had to fit in rodent burrows, most  breeds are small and lean and have a rough, wiry coat that requires little  maintenance. They have a long head, square jaw, and deep-set eyes. All  terriers are vocal and inclined to chase and confront. Most breeds were  named for the place where they were developed. See also Airedale terrier,  Bedlington terrier, Boston terrier, bull terrier, Dandie Dinmont terrier, fox  terrier, Irish terrier, pit bull terrier, Scottish terrier, Yorkshire terrier.</p><p>territorial behaviour In zoology, the actions by which an animal, or  group of animals, protects its territory from incursions by others of its  species. Territorial boundaries may be marked by sounds (e.g., birdsong),  scents, or even piles of dung. If such advertisement does not discourage  intruders, chases and fighting follow. Territories may be seasonal (usually  for nesting and feeding the young) or maintained permanently (for hunt�  ing and living). Territorial behaviour benefits the species by permitting  mating and rearing young without interruption and by preventing over�  crowding and minimizing competition for food.</p><p>territorial waters Waters under the sovereign jurisdiction of a nation  or state, including both marginal sea and inland waters. The concept origi�  nated in the 17th-century controversy over the status of the sea. Though  the doctrine that the sea must be free to all was upheld, a nation�s juris�  diction over its coastal waters was also recognized. Nations subscribing  to the Law of the Sea observe a territorial limit of 12 nautical mi (22 km)  from shore. Territorial rights include the airspace above those waters and  the seabed below them. See also high seas.</p><p>Terror, Reign of See Reign of Terror</p><p>terrorism Systematic use of violence to create a general climate of fear  in a population and thereby to bring about a particular political objective.  It has been used throughout history by political organizations of both the  left and the right, by nationalist and ethnic groups, and by revolutionar�  ies. Although usually thought of as a means of destabilizing or overthrow�  ing existing political institutions, terror also has been employed by  governments against their own people to suppress dissent; examples  include the reigns of certain Roman emperors, the French Revolution (see  Reign of Terror), Nazi Germany, the Soviet Union under Stalin, and Argen�  tina during the �dirty war� of the 1970s. Terrorism�s impact has been  magnified by the deadliness and technological sophistication of modern-  day weapons and the capability of the media to disseminate news of such  attacks instantaneously throughout the world. The deadliest terrorist  attack ever occurred in the United States on Sept. 11, 2001 (see September  11 attacks), when members of al-Qaeda terrorist network hijacked four  commercial airplanes and crashed two of them into the twin towers of the  World Trade Center complex in New York City and one into the Pentagon  building near Washington, D.C.; the fourth plane crashed near Pittsburgh,  Pa. The crashes resulted in the collapse of much of the World Trade Cen�  ter complex, the destruction of part of the southwest side of the Penta�  gon, and the deaths of some 3,000 people.</p><p>Terry, Eli (b. April 13, 1772, East Windsor, Conn.�d. Feb. 26, 1852,  Plymouth, Conn., U.S.) U.S. clockmaker. He made a specialty of one-day  wooden shelf clocks, especially his �perfected wood clock� known as the  Terry clock (1814). Using interchangeable parts made by mechanized  techniques, production at his Plymouth factory rose to as high as 10,GOO-  12,000 Terry clocks per year.</p><p>Terry, (Alice) Ellen (b. Feb. 27, 1847, Coventry, Warwickshire,  Eng.�d. July 21, 1928, Small Hythe, Kent) English actress. Born into a  family of actors, she made her stage debut at age nine. She acted with  several companies before joining Henry Irving as his leading lady (1878�  1902), playing a variety of Shakespearean roles in a notable partnership.  Her warmth, gentleness, and beauty made her one of the most popular  actresses in Britain and the U.S., and she continued to act until 1925. She  conducted a famous correspondence with the playwright George Bernard  Shaw. The actor, stage designer, and drama theorist Gordon Craig was  her son.</p><p>Tertiary Vt3r-she-,er-e\ Period Interval of geologic time, 65-1.8 mil�  lion years ago. It constitutes the first of the two periods of the Cenozoic  Era, the second being the Quaternary. The Tertiary has five subdivisions:  (from oldest to youngest) the Paleocene, Eocene, Oligocene, Miocene, and  Pliocene epochs. During most of the Tertiary, the spatial distribution of the</p><p>major continents was largely similar to that of today. Emergence and sub�  mergence of land bridges between continents critically affected the dis�  tribution of both terrestrial and marine animals and plants. Virtually all  the existing major mountain ranges were formed either partly or wholly  during the Tertiary.</p><p>Tertullian Uor-'tol-yonV (b. c. 155/160, Carthage�d. after 220,  Carthage) Early Christian theologian and moralist. Educated in Carthage,  he became impressed by the courage, morality, and uncompromising  monotheism of Christian martyrs, and he converted to Christianity. He  became a leading member of the African church and one of the early  Apologists. He devoted himself to writing for 20 years, producing works  on such topics as defense of the faith, prayer and devotion, and morality,  as well as the first Christian book on baptism, De baptismo. Later, dis�  mayed by the laxity he witnessed among even his orthodox contempo�  raries, he joined the prophetic movement known as Montanism, then left  it to form his own sect, which survived in Africa until the 5th century.</p><p>terza rima Vtert-so-'re-moX Verse form consisting of tercets, or three-  line stanzas, in which the second line of each rhymes with the first and  third lines of the next. The series ends with a separate line that rhymes  with the second line of the last stanza, so that the rhyme scheme is aba ,  bcb, cdc, ..., yzy, z . Dante, in The Divine Comedy (c. 1310-14), was the  first to use terza rima in a long poem. A demanding form, it has not been  widely adopted in languages less rich in rhymes than Italian. It was intro�  duced into England by Thomas Wyat in the 16th century. Poets who have  experimented with terza rima include Percy B. Shelley, Robert Browning,  Elizabeth Barrett Browning, and W.H. Auden; Derek Walcott�s book-length  Omeros is written in modified terza rima.</p><p>Teschen \'te-shon\ Former eastern European duchy. It was originally a  principality linked to the Polish duchy of Silesia, and passed in 1526 to  the Habsburgs. Though most of Silesia was seized by Prussia in 1742,  Teschen remained under Habsburg rule until the end of World War I. In  1920 Poland and Czechoslovakia contested and then divided the region;  Poland received the eastern district, including the city of Teschen (now  Cieszyn), while Czechoslovakia received the rest. The Czechs were forced  to cede their section to Poland in 1938. Germany occupied the entire  region until after World War II, when the 1920 borders were restored.</p><p>Tesla, Nikola (b.

He worked for  Thomas Alva Edison and George  Westinghouse but preferred indepen�  dent research. His inventions made  possible the production and distribu�  tion of alternating-current electric  power. He invented an induction coil  that is still widely used in radio tech�  nology, the Tesla coil (c. 1890); his  system was used by Westinghouse to  light the 1893 World�s Columbian  Exposition. Tesla established an  electric power station at Niagara  Falls in 1893. His research also  included work on a carbon button  lamp and on the power of electrical  resonance. He discovered terrestrial  stationary waves (1899-1900), prov�  ing that the Earth is a conductor. Due  to lack of funds, many of his ideas  remained only in his notebooks, which are still examined by engineers for  inventive clues.</p><p>Test Act (1673) Act passed by the British Parliament that required hold�  ers of civil and military offices to profess the established religion and to  receive Holy Communion according to the rites of the Church of England.  Though directed primarily against Roman Catholics, it extended in prin�  ciple to all non-Anglicans; it was modified in 1689 to enable most non-  Catholics to qualify. An act adopted in 1828 removed the test. In the U.S.  Constitution, Article VI prescribes that �no religious test� shall be required  for any officeholder.

In a  breed of dog, for example, in which the gene for black coat colour is  dominant over the gene for red coat colour (see dominance), a dog with a  black coat may be pure (with two genes for black coat colour) or hybrid  (with one gene for black and one for red). When its mating with a red-  coated dog (which always has two genes for red coat colour only) pro�  duces only black offspring, the black-coated parent must be pure, whereas  if some of the young are red, the parent must be hybrid.</p><p>testes or testicles Male reproductive organs (see reproductive system).  Humans have two oval-shaped testes 1.5-2 in. (4-5 cm) long that produce  sperm and androgens (mainly testosterone), contained in a sac (scrotum)  behind the penis. Each testis is divided into 200-400 lobes containing three  to 10 very thin coiled tubes (seminiferous tubules) each, which produce the  sperm and contract to expel them through a complex network of canals to  another structure in the scrotum, the epididymis, for temporary storage.  The cells in the testes are undeveloped in early childhood; at puberty they are  stimulated by hormones to develop into fertile sperm cells.</p><p>testicular cancer Malignant tumour of the testis, or testicle. Although  relatively rare, testicular cancer is the most common malignancy for men  between the ages of 20 and 34. It typically affects men between 15 and  39 years old. A developmental abnormality of males in which one or both  testes fail to descend into the scrotum about the time of birth increases  the risk of developing the cancer later in life. The most notable symptom  of testicular cancer is the formation of a painless lump in either testis.  Treatment usually consists of the surgical removal of the cancerous tes�  tis, followed by radiation therapy or chemotherapy if the cancer has  metastasized.</p><p>testing machine Machine used in materials science to determine the  properties of a material. Machines have been devised to measure tensile  strength, strength in compression, shear, and bending (see strength of  MATERIALS), DUCTILITY, HARDNESS, impact Strength (see IMPACT TEST), FRACTURE  toughness, creep, and fatigue. Standardization of machines and tests is the  province of the International Organization for Standardization, American  National Standards Institute, British Standards Institution, and many gov�  ernmental bodies. Many industries have special-purpose testing machines  for the materials they use.</p><p>testosterone Ues-'ta-stor-.onX Masculinizing sex hormone produced by  the testes. It is responsible for the development of the male sex organs and  secondary sex characteristics (e.g., facial hair, masculine musculature,  deep voice, and male-pattern baldness). Testosterone can be manufactured  by modifying other, less expensive steroids. It is used in the treatment of  hypogonadism, undescended testes (cryptorchism), and certain cancers.</p><p>tetanus Vte-t9-nss\ or lockjaw Acute bacterial disease caused by  Clostridium tetani (see Clostridium). Spores of this organism are common,  especially in soil; it thrives away from oxygen in deep wounds, especially  punctures. Its toxin stimulates nerves, causing muscle rigidity with fre�  quent spasms. This may occur around the site of the wound or, if the toxin  reaches spinal motor ganglia via the bloodstream, throughout the body.  The jaw muscles are almost always involved (lockjaw). Vaccination every  few years is the best protection; an antitoxin prevents or delays symptoms  in cases of suspect wounds but has limited value once they develop.  Treatment usually includes antibiotics, sedatives, and muscle relaxants.  Recovered patients are not immune.</p><p>Tetley (Jr.), Glen(ford Andrew) (b. Feb. 3, 1926, Cleveland, Ohio,  U.S.) American dancer, choreographer, and ballet director. He trained in  modern dance with Hanya Holm and Martha Graham. Between 1946 and  1962 he danced in Broadway musical productions as well as with dance  companies such as the American Ballet Theatre. He became a choreogra�  pher in 1962, forming his own company and creating Pierrot Lunaire.  Subsequently he staged works with most of the major dance companies  throughout the world. Tetley�s work helped to bring about a synthesis of  modern dance and classical ballet. His creative staging and daring, often  sexual, subject matter were sometimes controversial, but he was praised  for the passion and strong physicality of his work.</p><p>Teton \'te-,tan\ Range Segment of the Middle Rocky Mountains, north�  western Wyoming, U.S. The range extends 40 mi (64 km) across Wyo�  ming, from the southern boundary of Yellowstone National Park to Teton  Pass.

The body of the silver tetra  (Ctenobrycon spilurus) is flattened  sidewise.</p><p>tetracycline Any of a class of  broad-spectrum antibiotics with a  common basic structure, including doxycycline. They may be isolated  directly from several species of actinomycetes of the genus Streptomyces  or modified from the compounds isolated. They are the drugs of choice  in the treatment of cholera, rickettsial infections (see Rickettsia), psittaco�  sis, brucellosis, and tularemia; tetracyclines are also used in the treatment  of acne. Overuse of these and other antibiotics has led to drug resistance  in microorganisms.</p><p>Tetragrammaton V.te-tro-'gra-mo-.tanN Greek "having four let�  ters" Four Hebrew consonants yod, he, vav, and he �variously translit�  erated as JHVH, JHWH, YHWH, or YHVH�that together represent the  name of God.

The first tetrarchs ruled the four tetrarchies of Thessaly under  Philip II of Macedonia. Tetrarchs ruled in Galatia (in Asia Minor) before  the Roman conquest (169 bc) and still later in Hellenized Syria and Pal�  estine, where the title denoted the semi-independent ruler of a divided  kingdom or minor district. Herod the Great�s realm after his death (4 bc)  was ruled by his three sons, two of whom were called tetrarchs.</p><p>Teutates Vta-u-.ta-tezX or Toutates Vto-,ta-tez\ Celtic god, one of the  three mentioned by the Roman poet Lucan in the 1st century ad, the other  two being Esus and Taranis.

Founded in  1189-90 to nurse the sick in Palestine during the Third Crusade, it was  militarized in 1198 and given land in Jerusalem and Germany. It trans�  ferred its base of operations to eastern Europe in the 13th century, gain�  ing control of Prussia by 1283 and making Marienburg the centre of a  military principality (1309-1525). The order extended its influence until  it was defeated at the Battle of Tannenberg (1410). Another Polish victory  in 1466 forced the knights to cede lands to Poland and become vassals  of the Polish king. In 1525 the grand master in Prussia converted to Prot�  estantism, dissolved the order in Prussia, and became a duke under Polish  suzerainty. In other parts of Europe, especially Austria, the order survived  the Reformation. Napoleon declared the order dissolved in 1809 and redis�  tributed most of its remaining lands. In 1834 the Austrian emperor  refounded it as a charitable religious order, and it is now headquartered  in Vienna.</p><p>Glowlight tetras (Hemigrammus eryth�  rozonus)</p><p>JANE BURTON-BRUCE COLEMAN LTD.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1892 I Tewodros II &#x25BA; Thailand</p><p>Tewodros II \ta-'w6-dros\ or Theodore II (b. c. 1818�d. April 13,  1868, Magela, Eth.) Emperor of Ethiopia (1855-68). Often called Ethio�  pia�s first modern ruler, he came to the throne through the conquest of  other chiefs. He reunified the various Ethiopian kingdoms into one  empire, attempted to focus loyalty around the government rather than the  Ethiopian church, and worked to abolish the feudal system. Though he  failed in his aims, his example was followed by his successors. His reign  ended when a British force under Robert Napier attacked in response to  the imprisonment of several British citizens.</p><p>Texas State (pop., 2000: 20,851,820), southwestern U.S. Occupying  266,853 sq mi (691,146 sq km), it is the second largest state in both area  and population. Many of Texas�s boundaries are formed by water�the  course of the Red River on the north makes up two-thirds of the state�s  boundary with Oklahoma; on the east the state is bordered in part by  Arkansas, though the Sabine River forms most of Texas�s eastern bound�  ary with Louisiana; the Gulf of Mexico forms the coastal boundary to the  southeast; the Rio Grande carves a shallow channel that separates Texas  from Mexico on the southwest; the Panhandle section juts northward,  forming a counterpart in the western part of Oklahoma; and New Mexico  lies to the west. The capital of Texas is Austin. Plains and hills make up  the terrain, which ranges from the fertile prairie of the Coastal Plains on  the Gulf of Mexico through the central Great Plains grasslands to the arid  High Plains of the Panhandle. The forerunners of West Texas Indians  inhabited the area as much as 37,000 years ago. Some of the peoples later  formed the Caddo confederacy. Indians, including Apaches, were living in  the region when the Spanish arrived in 1528. The first settlement was  attempted in 1685 by the French, who claimed the region as part of Loui�  siana. In 1803 the U.S. acquired the French claim in the Louisiana Pur�  chase but relinquished it to Spain by treaty in 1819. It became part of  Mexico at Mexican independence in 1821. In 1836 Texans declared inde�  pendence from Mexico as the Republic of Texas (see Stephen Austin; Sam  Houston). After a 10-year struggle to remain independent, Texas became  the 28th U.S. state in 1845. Its boundary with Mexico was fixed after the  Mexican War (1848). In the American Civil War it seceded from the Union  (1861); it was readmitted in 1869. After the war, railroad building and  increased shipping helped expand the economy, and the discovery of oil  in 1901 transformed it. While Texas still leads all other states in oil and  natural gas production and in petroleum-refining capacity, its manufac�  ture of electronics, aerospace components, and other high-technology  items is increasingly important. It is also the leading cotton, beef cattle,  and sheep producer in the U.S.</p><p>Texas, University of U.S. state university system with 13 campuses  throughout the state. It was founded in 1883. The main campus, at Aus�  tin, is the second most populous campus in the U.S. It is a comprehen�  sive research and teaching institution, offering about 100 undergraduate  programs and about 190 graduate degree programs. There are more than  85 organized research units on campus, including centres for biomedical  research, economic geology, and cognitive science. The Lyndon B.

They did not wear uniforms or salute their  officers but were highly disciplined and known for their marksmanship,  making the six-shooter (the Colt revolver) the weapon of the West. At  their peak in the 1870s, the Rangers brought law and order to hundreds  of miles of Texas frontier. In 1935 they were merged with the state high�  way patrol.</p><p>Texcoco \tas-'ko-k6\, Lake Lake, central Mexico.

The word originally referred only to  woven fabrics but now includes knitted, bonded, felted, and tufted fab�  rics as well. The basic raw materials used in textile production are fibres,  either obtained from natural sources (e.g., wool) or produced from chemi�  cal substances (e.g., nylon and polyester). Textiles are used for wearing  apparel, household linens and bedding, upholstery, draperies and curtains,  wall coverings, rugs and carpets, and bookbindings, in addition to being  used widely in industry.</p><p>Tezcatlipoca V.tas-kat-le-'po-koV Omnipotent god of the Aztec pantheon  and god of the constellation Ursa Major. The protector of slaves, he  severely punished masters who ill-treated them. He is said to have put an  end to the Toltecs� golden age. Each year his worshipers selected a hand�  some prisoner of war who was allowed to live in princely luxury for a  year before being sacrificed. Tezcatlipoca is represented in art with an  obsidian mirror, in which he sees all, on his chest or in place of a foot.</p><p>Thackeray, William Makepeace (b. July 18, 1811, Calcutta,  India�d.

His early writ�  ings appear in such volumes as The  Book of Snobs (1848), a collection of  his articles from Punch ; and Miscel�  lanies (1855-57), which includes the  historical novel Barry Lyndon  (1844). His fame rests chiefly on the  novels Vanity Fair ( 1847�48), a pan�  oramic survey of English manners  and human frailties set in the Napo�  leonic era, and Henry Esmond  (1852), set in the early 18th century.</p><p>Pendennis (1848-50) is a partly fic�  tionalized autobiography.

Area: 198,116 sq mi (513,119 sq km).  Population (2005 est.): 64,186,000. Capital: Bangkok. The population is  predominantly Thai, with significant Chinese, Khmer, and Malay minori�  ties. Language: Thai (official). Religions: Buddhism (official); also Islam.  Currency: Thai baht. The country encompasses forested hills and moun�  tains, a central plain containing the Chao Phraya River delta, and a plateau  in the northeast. Its market economy is based largely on services (nota�  bly trade) and light industries; agriculture employs a large proportion of  the workforce. Thailand is a major producer of tungsten and tin. Among  its chief agricultural products are rice, corn, rubber, soybeans, and pine�  apples; manufactures include clothing, canned goods, electronic equip�  ment, and cement. Tourism is also important. Thailand is a constitutional  monarchy with two legislative houses; its chief of state is the king, and  the head of government is the prime minister. The region of Thailand has  been continuously occupied for 20,000 years. It was part of the Mon and  Khmer kingdoms from the 9th century ad. Thai-speaking peoples immi�  grated from China c. the 10th century. During the 13th century two Thai  states emerged: the Sukhothai kingdom, founded c. 1220 after a successful  revolt against the Khmer, and Chiang Mai (which evolved into the king�  dom of Lan Na with Chiang Mai as its capital), founded in 1296 after  defeating the Mon. In 1351 the Tai kingdom of Ayutthaya (Siam) suc�  ceeded the Sukhothai. Myanmar (Burma) was its most powerful rival,  Burman armies occupying it briefly in the 16th century and destroying it  in 1767. The Chakri dynasty came to power in 1782, moved the capital  to Bangkok, and extended its empire along the Malay Peninsula and into  Laos and Cambodia. The empire was formally named Siam in 1856.

He  suffered from health problems at a young age, and fearing his life would  not be a long one, he threw himself into his career, joining Universal Pic�  tures after completing high school. He soon became Universal�s studio  manager in Hollywood. Hired by MGM as head of production in 1925,  he became known as the �boy wonder of Hollywood.� He tightly con�  trolled MGM�s output by supervising script selection and final film edit�  ing, and he was responsible for the high quality of movies such as The  Barretts of Wimpole Street (1934), Mutiny on the Bounty (1935), and  Romeo and Juliet (1936) and for making stars of Nelson Eddy and  Jeanette MacDonald with Naughty Marietta (1935).

None of his writings survive, and no contemporary sources exist.  The claim that Thales was the founder of Western philosophy rests pri�  marily on Aristotle, who wrote that he was the first to suggest a single  material substratum for the universe, namely water. Thales� significance  lies in his attempt to explain nature by the simplification of phenomena  and in his search for causes within nature itself rather than in the caprices  of anthropomorphic gods.</p><p>thalidomide Uho-'li-do-.mldX Drug formerly used as a sedative and to  prevent morning sickness during pregnancy. Synthesized in 1954, it was  introduced in almost 50 countries, including West Germany and Britain,  where it became popular because it was effective and huge overdoses were  not fatal. In 1961 it was found to cause congenital disorders; when it is</p><p>taken in early pregnancy, some 20% of fetuses have phocomelia (defec�  tive development of the limbs) and other deformities; 5,000-10,000 such  babies were born. It was never distributed for clinical use in the U.S. (see  Helen Brooke Taussig). Thalidomide appears effective against inflamma�  tory and autoimmune disorders, including certain late-stage AIDS symp�  toms, and is licensed for use in such treatments in some countries.</p><p>thallus Vtha-bs\ Plant body of algae, fungi (see fungus), and similar  simple, plantlike organisms. Composed of filaments or plates of cells, a  thallus ranges in size from a single-celled structure to a complex treelike  form.

Most thallus plants are currently classified  as complex protists.</p><p>Thames \'temz\ / Battle of the (Oct. 5, 1813) Decisive U.S. victory  over the British in the War of 1812. After the British defeat in the Battle  of Lake Erie, U.S. troops under Gen. William H. Harrison pursued retreat�  ing British soldiers across the Ontario peninsula. The British force of 600  regulars and 1,000 Indians under Tecumseh met 3,500 U.S. troops at the  Thames River near Moraviantown, Ont. The outnumbered British were  quickly defeated, and Tecumseh was killed.

It is tidal for about 65 mi (104 km). Known by  the Romans and by early English chroniclers, it has been celebrated by  bards throughout history. One of the world�s most important commercial  waterways, it is navigable by large vessels to London.</p><p>thanatology \ l tha-n3- , ta-b-je\ Description or study of death and dying  and of the psychological mechanisms of dealing with them. One influen�  tial model proposed in 1969 by the psychiatrist Elisabeth Kiibler-Ross (b.  1926) described five basic stages: denial, anger, bargaining, depression,  and acceptance; however, not all dying persons follow a regular, clearly  identifiable series of responses to their situation. Thanatology also exam�  ines attitudes toward death, the meaning and behaviours of bereavement  and grief, and other matters.</p><p>Thanatos Vtha-no-.tasX Ancient Greek personification of death. He was  the son of Nyx, goddess of night, and brother to Hypnos, god of sleep.  He appeared to humans to carry them off to the underworld when the time  allotted to them by the Fates had expired. Thanatos was once defeated by  Heracles, who wrestled him to save the life of Alcestis, and he was tricked  by Sisyphus, who wanted a second chance at life.</p><p>Than? \'tha-ne\ dynasty also Al Than! ("Than? family") Ruling  family of Qatar. They are from the Tamlm tribe, which migrated eastward  from central Arabia to the Qatar peninsula in the mid-19th century. There  have been eight leaders from 1868 to the present. The second sheikh,  Qasim ibn Muhammad (1878-1913), is considered Qatar�s founder. The  seventh sheikh, Khallfah ibn Hamad (r. 1972-95), was instramental in  obtaining Qatar�s independence from Britain in 1971 and became the first  emir. The clan comprises about two-fifths of the native Qatari population.</p><p>Thanksgiving Day U.S. holiday. It originated in the autumn of 1621  when Plymouth governor William Bradford invited neighbouring Indians  to join the Pilgrims for a three-day festival of recreation and feasting in  gratitude for the bounty of the season, which had been partly enabled by  the Indians� advice. Neither the standard Thanksgiving meal of turkey,  cranberry sauce, and pumpkin pie nor the family orientation of the day  reflects the Plymouth event, however. Proclaimed a national holiday in  1863, Thanksgiving is celebrated on the fourth Thursday in November  (though it was moved back one week in 1939-41 to extend the Christ�  mas shopping season). Canada adopted Thanksgiving as a national holi�  day in 1879; since 1957 it has been celebrated on the second Monday in  October.</p><p>Thant, U (b. Jan. 22, 1909, Pantanaw, Burma�d.

It covers 146 sq mi (379 sq km). It was colonized c. 700 bc by  Greeks from Paros who exploited its gold mines and founded a school of  sculpture. The Persians seized Thasos in the early 5th century bc; it later  came under the authority of Athens as a member of the Delian League. A  Macedonian dependency in 202 bc, Thasos passed to Rome in 196 bc.  The Turks ruled it from the mid-15th  century ad until it was ceded to  Greece in 1913. Its industries include  boatbuilding, fishing, and tourism,  and it has been a base for offshore oil  exploration since the 1970s.

Oct. 13, 1925, Grantham, Lin�  colnshire, Eng.) British politician  and prime minister (1979-90). She  earned a degree from the University  of Oxford, where she was one of the  first woman presidents of the Oxford  University Conservative Associa�  tion, then worked as a research  chemist. After her marriage to Denis</p><p>Thatcher (1951), she read for the bar and specialized in tax law. She was  elected to Parliament in 1959 and served as secretary of state for educa�  tion and science (1970-74). As a member of the Conservative Party�s  newly energetic right wing, she succeeded Edward Heath as party leader  in 1975. In 1979 she became Britain�s first woman prime minister. She  advocated individual initiative, confronted the labour unions, privatized  national industries and utilities and attempted to privatize aspects of health  care and education, pursued a strong monetarist policy, and endorsed a  firm commitment to NATO. Her landslide victory in 1983 owed partly to  her decisive leadership in the Falkland Islands War. A split in party ranks  over European monetary and political integration led to her resignation  in 1990, by which time she had become Britain�s longest continuously  serving prime minister since 1827.</p><p>theatre Live performance of dramatic actions in order to tell a story or  create a spectacle. The word derives from the Greek theatron (�place of  seeing�). Theatre is one of the oldest and most important art forms in cul�  tures worldwide. While the script is the basic element of theatrical per�  formance, it also relies in varying degrees on acting, singing, and dancing,  as well as on technical aspects of production such as stage design. The�  atre is thought to have its earliest origins in religious ritual; it often enacts  myths or stories central to the belief structure of a culture or creates com�  edy through travesty of such narratives. In Western civilization, theatre  began in ancient Greece and was adapted in Roman times; it was revived  in the medieval liturgical dramas and flourished in the Renaissance with  the Italian commedia dell'arte and in the 17th�18th centuries with estab�  lished companies such as the ComiiDIE-Francaise. Varying theatrical forms  may evolve to suit the tastes of different audiences (e.g., in Japan, the  kabuki of the townspeople and the no theatre of the court). In Europe and  the U.S. in the 19th and early 20th centuries theatre was a major source  of entertainment for all social classes, with forms ranging from burlesque  shows and vaudeville to serious dramas performed in the style of the Mos�  cow Art Theatre. Though the musicals of Broadway and the farces of Lon�  don�s West End retain their popular appeal, the rise of television and  movies has eroded audiences for live theatre and has tended to limit its  spectators to an educated elite. See also little theatre.</p><p>theatre Building or space in which performances are given before an  audience. It contains an auditorium and stage. In ancient Greece, where  Western theatre began (5th century bc), theatres were constructed in natu�  ral hollows between hills. The audience sat in a tiered semicircle facing  the orchestra, a flat circular space where the action took place. Behind the  orchestra was the skene. The theatres of Elizabethan England were open  to the sky, with the audience looking on from tiered galleries or a court�  yard. During this period the main innovation was the rectangular thrust  stage, surrounded on three sides by spectators. The first permanent indoor  theatre was Andrea Palladio�s Olimpico Theatre in Vicenza, Italy (1585).  The Famese Theatre in Parma (1618) was designed with a horseshoe�  shaped auditorium and the first permanent proscenium arch. Baroque Euro�  pean court theatres followed this arrangement, elaborating on the interior  with tiered boxes for royalty. Richard Wagner�s Festspielhaus in Bayreuth,  Ger. (1876), with its fan-shaped seating plan, deep orchestra pit, and  darkened auditorium, departed from the Baroque stratified auditorium and  reintroduced Classical principles that are still in use. The proscenium the�  atre prevailed in the 17th-20th centuries; though still popular in the 20th  century, it was supplemented by other types of theatre, such as the thrust  stage and theatre-in-the-round. In Asia, stage arrangements have remained  simple, with the audience usually grouped informally around an open  space; notable exceptions are the no drama and kabuki of Japan.

Founded in New York City in  1918 by Lawrence Langner (1890-1962) and others, the group proposed  to produce high-quality, noncommercial plays. Its board of directors  shared responsibility for choice of plays, management, and production.  After the premiere of George Bernard Shaw�s Heartbreak House in 1920,  the Guild became his U.S. agent and staged 15 of his plays. It also pro�  duced successful plays by Eugene O'Neill, Maxwell Anderson, and Robert  Sherwood and featured actors such as the Lunts and Helen Hayes. It helped  develop the American musical by staging Porgy and Bess (1935), Okla�  homa! (1943), and Carousel (1945); it also produced the radio series The�  atre Guild on the Air (1945-53) and presented plays on television.</p><p>theatre-in-the-round or arena stage Theatre in which the stage  is located in the centre of the auditorium with the audience seated on all  sides.

From the 17th century the proscenium stage limited audience seat�  ing to the area directly in front of the stage. In the 1930s, plays at Mos�  cow�s Realistic Theatre were produced in the round and the arena stage  began to gain favour in Europe and the U.S. Its advantages are its infor�  mality and the rapport it creates between audience and actors, but it  requires actors to turn constantly to address new sections of the audience.</p><p>Theatre National Populaire \ta- , a-tr 5 -na-syo- , nal-p6-p[E- , ler\  (TNP) French national theatre created in 1920 to bring theatre to the gen�  eral public. Under the direction of its founder, Firmin Gemier (1869-1933),  the TNP initially offered productions from the other national companies. In  1951 it established a permanent company under Jean Vilar (1951-63), giv�  ing 150 performances a year in and around Paris, charging ticket prices  competitive with the movies. By 1959 it was as popular as the Comedie-  Francaise. In 1972, in an effort to decentralize the theatre, the government  transferred its title to a subsidized theatre company in Lyon.</p><p>Theatre of Cruelly Theory advanced by Antonin Artaud, who  believed the theatre�s function was to rid audiences of the repressive  effects of civilization and liberate their instinctual energy. He proposed to  do so by shocking them with mythic spectacles that would include groans,  screams, pulsating lights, and oversized stage puppets. He described the  Theatre of Cruelty in his book The Theatre and Its Double (1938). Though  only one of his plays, Les Cenci, was ever produced in accordance with  his theory, his ideas influenced avant-garde movements such as the Living  Theatre and the Theatre of the Absurd.</p><p>Theatre of Fact or documentary theatre Movement to bring  social issues to the stage by emphasizing factual information over aes�  thetic considerations. An outgrowth of the Living Newspaper technique  employed in the 1930s by the WPA Federal Theatre Project in the U.S.,  the form became popular in the 1960s. In Germany Rolf Hochhuth�s The  Representative (1963), Peter Weiss�s The Investigation (1965), and Heinar  Kipphardt�s In the Matter of J. Robert Oppenheimer (1964) examined  recent historical events through authentic documentary sources such as  trial transcripts and statistics. The movement influenced later political  drama in Europe and the U.S.</p><p>Theatre of the Absurd Body of dramatic works of the 1950s and  �60s that expressed the existentialist philosophy of meaninglessness and  the absurdity of life. Playwrights such as Arthur Adamov, Edward Albee,  Samuel Beckett, Jean Genet, Eugene Ionesco, and Harold Pinter created  Absurdist plays without traditional plots and with characters who engaged  in circular, purposeless conversations. Beckett�s Waiting for Godot  (1953), in which two tramps wait for a mysterious man who never arrives,  is a classic of the genre.</p><p>theatricalism Twentieth-century theatrical movement that emphasized  artifice in reaction to 19th-century naturalism. Marked by stylized acting,  a stage projecting into the audience, and frank scenic artifices and con�  ventions, it did not strive to create the illusion of reality but rather to  remind the audience of their role as viewers and critics of the artwork in  progress before them. Theatricalism was found in the Expressionist,  Dadaist, and Surrealist drama of the early 20th century and has contin�  ued as a current in the modern theatre.</p><p>Thebes \'thebz\ biblical No Ancient city, Egypt. Its remains are located  on the Banks of the Nile River. In early times it also included Karnak and  Luxor; the Valley of the Kings is situated nearby. The earliest monuments  in the city itself date from the 11th dynasty (c. 21st century bc), when the  rulers of Thebes united Egypt and made Thebes the capital of Upper  Egypt. It remained the capital until the end of the Middle Kingdom (c.  18th century bc). It was obscured for two centuries under the rule of vari�  ous foreign invaders, after which the kings of Thebes restored Egyptian  rule in the 16th century bc and again made it the capital. It flourished as  Egypt�s political and religious centre throughout the New Kingdom period  and was well known for achievements in sculpture and architecture. It  began to decline in the 12th century bc and was sacked by Assyrians in  the mid-7th century bc, by Persians in the 6th-4th centuries bc, and by  Romans c. 30 bc. Its ruins include great temples and tombs, including the  Temple of Amon at Karnak (c. 20th century bc), the tomb of Tutankha�  men in the Valley of the Kings, and the great mortuary temples of Ramses  II and Hatshepsut. The region�s antiquities were collectively designated a  UNESCO World Heritage site in 1979.</p><p>Thebes Greek Thivai \'the-ve\ Ancient city, Boeotia, east-central  Greece, one of the chief Greek city-states. Traditionally said to have been</p><p>founded by Cadmus, it was the seat of the legendary Oedipus and the set�  ting for many classic Greek tragedies. The building of its celebrated  seven-gated wall is usually attributed to Amphion. It was a centre of Myce�  naean power in the Bronze Age (c. 1500-1200 bc). Hostility to Athens led  it to side with the Persians in the Persian Wars and with Sparta in the  Peloponnesian War. Thebes and Sparta subsequently clashed, and the vic�  torious Spartans occupied it. It revolted c. 380 bc and defeated Sparta at  the battles of Tegyra (375 bc) and Leuctra (371 bc). For the next 10 years  it was the chief military power in Greece. It joined Athens against Philip  II of Macedon and shared the defeat at the Battle of Chaeronea in 338 bc.  It was sacked by Alexander the Great in 336 and eventually fell to Rome  in the 1st century bc. Among the few ancient remains are remnants of the  city walls, the Mycenaean palace (c. 1450-1350 bc), and a temple of  Apollo.</p><p>theft In law, the crime of taking the property or services of another with�  out consent. Under most statutes, theft encompasses the crimes of larceny,  robbery, and burglary. Larceny is the crime of taking and carrying away  the goods of another with intent to steal. Grand larceny, or larceny of  property of substantial value, is a felony, whereas petty larceny, or lar�  ceny of less valuable property, is a misdemeanour. The same principle  applies to grand theft and petty theft, which need not necessarily involve  the �carrying away� of property and may include the theft of services.  Robbery is an aggravated form of larceny involving violence or the threat  of violence directed against the victim in his presence. Burglary is defined  as the breaking and entering of the premises of another with an intent to  commit a felony within. Two offenses usually distinguished from theft are  EMBEZZLEMENT and FRAUD.</p><p>theism View that all observable phenomena are dependent on but dis�  tinct from one supreme being. The view usually entails the idea that God  is beyond human comprehension, perfect and self-sustained, but also  peculiarly involved in the world and its events. Theists seek support for  their view in rational argument and appeals to experience. Arguments for  God�s existence are of four principal types: cosmological, ontological,  teleological, or moral. A central issue for theism is reconciling God, usu�  ally understood as omnipotent and perfect, with the existence of evil. See  also AGNOSTICISM, ATHEISM, DEISM, MONOTHEISM, POLYTHEISM, THEODICY.</p><p>Themistocles Uhe-'mis-to-.klezN (b. c. 524�d. c. 460 bc) Athenian  politician and naval strategist. As archon (493) he built defensible har�  bours at Piraeus. In 483 he persuaded the assembly to increase the navy,  believing it represented Athens�s best chance of warding off Persian  invaders. When the invasion of Xerxes I did come, a Greek naval force at  first yielded to Persia at Artemisium, but Themistocles lured Xerxes�  remaining ships to their destruction at the Battle of Salamis. Despite his  victory, Athens later ostracized the strongly democratic Themistocles  (472) as the city�s politics turned reactionary. When Sparta later accused  him of complicity with Persia, he fled the Peloponnese and, until his death,  served as governor of some Asian Greek cities still under Persian rule.</p><p>theocracy \the-'a-kr9-se\ Government by divine guidance or by offi�  cials who are regarded as divinely guided. In many theocracies, govern�  ment leaders are members of the clergy, and the state�s legal system is  based on religious law. Theocratic rule was typical of early civilizations.  The Enlightenment marked the end of theocracy in most Western coun�  tries. Contemporary examples of theocracies include Saudi Arabia, Iran,  and the Vatican. See also church and state; divine kingship.</p><p>Theocritus Uhe-'a-kro-tosV (b. c. 300, Syracuse, Sicily�d. 260 bc)  Greek poet. Little is known of his life. His surviving poems consist of  bucolics and mimes, set in the country, and epics, lyrics, and epigrams,  set in towns. The bucolics, his most characteristic and influential works,  introduced the pastoral convention into poetry and were the sources of  Virgil�s Eclogues and much Renaissance poetry and drama. Theocritus�s  best-known idylls include Thyrsis, a lament for Daphnis, the shepherd poet  of mythology, and Thalysia (�Harvest Festival�), which presents the  poet�s friends and rivals in the guise of rustics.</p><p>theodicy \the-'a-d3-se\ Argument for the justification of God, concerned  with reconciling God�s goodness and justice with the observable facts of  evil and suffering in the world. Most such arguments are a necessary  component of theism. Under polytheism, the problem is solved by attribut�  ing evil to a conflict of wills between deities. The solution is less simple  in monotheism, and it can take several forms. In some approaches, the per�  fect world created by God was spoiled by human disobedience or sin. In  others, God withdrew after creating the world, which then fell into decay.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1896 I Theodora &#x25BA; theology</p><p>Theodora (b. c. 497�d. June 28, 548, Constantinople) Byzantine  empress, wife of Justinian I. The  daughter of a bear keeper at the Hip�  podrome in Constantinople, she  became an actress and the mistress of  Justinian. He married her in 525, and  when he became emperor in 527 she  was proclaimed empress. Probably  the most powerful woman in Byzan�  tine history, she was her husband�s  most trusted adviser, sponsoring  legal reforms and wielding great  influence in diplomacy, military  appointments, and internal politics.</p><p>Her impassioned speech gave Justin�  ian the strength to order the brutal  suppression of the Nika revolt (532)  and save his empire. She recognized  the rights of women and ended per�  secution of Monophysite Christians,  with whom she sympathized.</p><p>Theodorakis Vhe-o-do-'ra-kisX,</p><p>Mikis (b. July 29, 1925, island of  Chios, Greece) Greek composer. He  studied at the Athens and Paris con�  servatories. A member of the war�  time resistance, he remained active  in politics, serving several times in the Greek parliament. As a Commu�  nist Party member, he was arrested during the 1967 military coup and  only released in 1970 under international pressure. He is best known out�  side Greece for his film scores, including Zorba the Greek (1964), Z  (1969), and State of Siege (1972), but he also composed much concert  music, including seven symphonies, four operas, ballets (including Anti�  gone, 1959), and more than 1,000 songs. He is esteemed in his homeland  as a national hero.</p><p>Theodore I Lascaris Vlas-ko-rosV (b. c. 1174�d. November 1221,  Nicaea, Nicaean empire) First emperor of Nicaea, the Byzantine  government-in-exile during the Crusaders� occupation of Constantinople.  He distinguished himself during the sieges of Constantinople in the Fourth  Crusade (1203-04). After the Byzantine capital fell, he gathered a band  of refugees, first at Brusa and then at Nicaea, and formed a new Byzan�  tine state. He took the title of emperor in 1208 and successfully defended  Nicaea against the Crusaders, the Turks, and his rival emperor David  Comnenus. He signed a treaty (c. 1214) with the Latin emperor of Con�  stantinople defining Nicaea�s boundaries and betrothed his daughter to the  heir to the Latin imperial throne.</p><p>Theodore II See Tewodros II</p><p>Theodore of Canterbury, Saint (b. c. 602, Tarsus, Cilicia, Asia  Minor�d. Sept. 19, 690, Canterbury, Kent, Eng.; feast day September  19) Seventh archbishop of Canterbury (668-690). He was sent from Rome  to Canterbury, where he helped establish a famous school at the monas�  tery later known as St. Augustine�s. Theodore organized and centralized  the English church, calling its first general synod (672) to end Celtic  practices, affirm church doctrine, and divide dioceses. He deposed Wil�  frid as bishop of York in 677 but restored him in 686; he also made peace  between King Aethelred of Mercia and King Ecgfrith of Northumbia.</p><p>Theodore of Mopsuestia \,map-su-'es-ch3\ (b. c. 350, Antioch,  Syria�d. 428/429, Mopsuestia, Cilicia) Syrian theologian and spiritual  head of the school of Antioch. He entered a monastery near Antioch,  where he lived and studied until 378. He was ordained in 381 and became  bishop of Mopsuestia c. 392. His exegetical writings used scientific, criti�  cal, philological, and historical methods of analysis that anticipated mod�  ern scholarship. Theologically, he believed that Christ had two natures,  divine and human, in some kind of union. He stressed the literal sense of  scripture and opposed allegorical interpretations. The second Council of  Constantinople (553) condemned his views, but he was venerated by the  Nestorian church as �the Interpreter.� He is said to have introduced into  the Nestorian church the doctrine of universal salvation.</p><p>Theodore Roosevelt National Park Preserve, west-central North  Dakota, U.S. Established in 1947, it commemorates Pres. Theodore  Roosevelt�s interest in the American West. The 110-sq-mi (285-sq-km) park</p><p>contains several sites along the Little Missouri River, including a petrified for�  est, Wind Canyon, eroded badlands, and Roosevelt�s Elkhom Ranch cabin.</p><p>Theodoret Uhe-'ad-s-roA of Cyrrhus (b. c. 393, Antioch, Syria�d.  c. 458/466) Syrian theologian and bishop whose writings were a moder�  ating influence on the 5th-century Christological disputes. First a monk,  he became bishop of Cyrrhus (near Antioch) by 423. Influenced by St.  John Chrysostom and Theodore of Mopsuestia, he opposed allegorical inter�  pretations of scripture and attributed a human nature to Christ. Accused  of being a Nestorian heretic, he made conciliatory statements accepting  the term �god-bearer� for Mary (thereby stressing Jesus� divinity). He was  declared a heretic nevertheless (449) and was sent into exile. He was par�  tially vindicated by the Council of Chalcedon (451), which agreed to  declare him orthodox provided he condemn his friend Nestorius, and he  reluctantly complied.</p><p>Theodoric known as Theodoric the Great (b. 454 �d. Aug. 30,  526) King of the Ostrogoths and founder of the Ostrogothic kingdom in  Italy. Sent by the Byzantine emperor Zeno to invade Italy in 488, he made  himself sole ruler by 493 and murdered Odoacer by treachery. With  Ravenna as his capital he staved off the Franks and Bulgarians, and he  held sway over a kingdom that included Sicily, Dalmatia, and some Ger�  man lands. An Arian (see Arianism), he tolerated Catholicism and pro�  moted peace between Goths and Romans.</p><p>Theodosius I \,the-3-'d6-she-3s\ or Theodosius the Great in full  Flavius Theodosius (b. Jan. 11, 347, Cauca, Gallaecia [Spain]�d.  Jan. 17, 395, Mediolanum) Roman emperor of the East (379-392) and of  East and West (392-395). Born of Christian parents, he served in the  military under his father, a general. He distinguished himself against the  Sarmatians and was proclaimed coemperor by Gratian to rule in the east�  ern empire (379). To settle the contentious debate over true Christianity,  he adopted the Nicene Creed as the Christian norm (380). He reached a  treaty with the Visigoths (382). When the Spanish general Maximus over�  threw the new coemperor in the western empire (387), Theodosius  defeated the usurper (388) and claimed supreme authority over the whole  empire (392). He argued with St. Ambrose over the role of the church in  imperial affairs but did not grant power to the church. In 392 forces advo�  cating paganism led by Arbogast and Eugenius took power in Rome. In  394 Theodosius defeated them and claimed the Christian God victorious  over the pagan gods.</p><p>Theodosius I Boradiotes V.bor-o-'dI-o-.tezX (b. Antioch�d. after  1183, Constantinople) Greek Orthodox patriarch of Constantinople ( 1179�  83). As patriarch, he upheld stringent conversion requirements for con�  verts from Islam against the wishes of Emperor Manuel I Comnenus. He  also opposed Manuel�s overtures to Pope Alexander III and the Latin  church of the West, refusing to cooperate with a proposed reunion of the  two branches of Christianity. The succeeding emperor forced Theodosius  to abdicate.</p><p>Theodosius II (b. April 10,401, Constantinople�d. July 28,450) East�  ern Roman emperor (408-450). In 402 he was made coemperor with his  father, Arcadius (son of Theodosius I), then became sole ruler of the East  at age seven, initially under a regency. A gentle, scholarly man, he allowed  relatives and ministers to dominate his government. His generals twice  repelled the Persians (422, 447) but failed to evict the Vandals from  Roman Africa (429) and to prevent Attila�s invasions (441-443,447). The  Nestorian heresy caused internal upheaval. Theodosius was credited with  building the wall around Constantinople (413), founding the University  of Constantinople (425), and promulgating the Theodosian Code (438).</p><p>Theodosius of Alexandria (fl. 6th century�d. June 566, Constan�  tinople) Patriarch of Constantinople (535-566). A moderate Monophys�  ite, he was opposed by more extreme Monophysites and did not accept  the orthodox position expressed by the Council of Chalcedon (451). He  was prevented from administering his patriarchate by his detention in  Constantinople, but he influenced the independent churches in Antioch,  Syria, and Egypt. See Monophysite heresy.</p><p>theology Study of the nature of God and the relationship of the human  and divine. The term was first used in the works of Plato and other Greek  philosophers to refer to the teaching of myth, but the discipline expanded  within Christianity and has found application in all theistic religions (see  theism). It examines doctrines concerning such subjects as sin, faith, and  grace and considers the terms of God�s covenant with humankind in mat�  ters such as salvation and eschatology.

From his writings it can be deduced that he was a practicing craftsman  of the Benedictine order.</p><p>theorem In mathematics or logic, a statement whose validity has been  established or proved. It consists of a hypothesis and a conclusion, begin�  ning with certain assumptions that are necessary and sufficient to estab�  lish a result. A system of theorems that build on and augment each other  constitutes a theory. Within any theory, however, only statements that are  essential, important, or of special interest are called theorems. Less impor�  tant statements, usually stepping-stones in proofs of more important  results, are called lemmas. A statement proved as a direct consequence of  a theorem is a corollary of the theorem. Some theorems (and even lem�  mas and corollaries) are singled out and given titles (e.g., Godel's theo�  rem, FUNDAMENTAL THEOREM OF ALGEBRA, FUNDAMENTAL THEOREM OF CALCULUS,</p><p>Pythagorean theorem).</p><p>theosophy \the-'a-so-fe\ Religious philosophy with mystical concerns  that can be traced to the ancient world. It holds that God, whose essence  pervades the universe as an absolute reality, can be known only through  mystical experience (see mysticism). It is characterized by esoteric doctrine  and an interest in occult phenomena. Theosophical beliefs are found in  Neoplatonism, Gnosticism, and among students of the Kabbala, but Jakob  Bohme, who developed a complete theosophical system, is often called the  father of modern theosophy. Today theosophy is associated with the Theo�  sophical Society, founded by Helena Blavatsky in 1875.

Sent to  quell an insurrection at Piraeus, he instead led the mutineers in deposing  the Council. In 410 he helped Alcibiades defeat the Peloponnesian navy at  Cyzicus (see Peloponnesian War). Under Alcibiades he taxed shipping  from the Black Sea, helping the economy of Athens to recover and help�  ing restore full constitutional government. During the siege of Athens  (405/404) he was sent to deal with Lysander and negotiated terms of capitu�  lation as Athens underwent three months of starvation. A leader of the  Thirty Tyrants installed by Lysander, he fell out with Critias and was forced  to drink hemlock.</p><p>Therapeutae Vher-o-'pyii-teV Greek "Worshipers" Sect of Jewish  ascetics believed to have settled along Lake Mareotis near Alexandria in  the 1st century ad. Their origin and fate are unknown, and the only  account of them is attributed to Philo Judaeus. They shared with the Ess-  enes a dualistic view of the body and soul (see dualism) but differed from  them in that their objective was �wisdom.� They viewed the scriptures as  allegorical. Devoting themselves entirely to prayer and spiritual exercise,  members lived in isolation for six days of the week and met on the Sab�  bath for discourse and a common meal.</p><p>therapeutics \,ther-3-'pyu-tiks\ Treatment and care to combat disease  or alleviate pain or injury. Its tools include drugs, surgery, radiation  therapy, mechanical devices, diet, and psychiatry. Treatment may be  active, to cure a disease (requiring no further treatment after recovery),  treat it long-term, or heal a wound; symptomatic, to relieve symptoms  until the immune system heals the body; supportive, to keep body functions  going until the disease clears; or palliative, to minimize discomfort for  patients with no chance of recovery. It almost always includes prevention,  usually tertiary (see preventive medicine). Therapeutic measures can be cho�  sen, combined, and tailored based on accurate diagnosis to fit each patient.

It  is relatively uninfluenced by other indigenous belief systems. It is believed  to have survived intact from the 500 Elders, who followed in the tradi�  tion of the monks of the first Buddhist sangha. Theravada has no hierar�  chical authority structure, though seniority is respected in the sangha. It  accepts the Pali canon (see Tripitaka) as authoritative scripture.

Born into a devout Roman Catholic fam�  ily, she entered the convent at Lisieux at age 15, where she was plagued  by depression and guilt but was known for her sweetness of temper. At  the insistence of the prioress, she wrote an account of her spiritual devel�  opment, in which she called for an absolute and childlike surrender to  God, which she called the Little Way. After her death from tuberculosis  at age 24, the book was published as Story of a Soul (1898) and became  widely popular, and her burial site at Lisieux became a place of pilgrim�  age.</p><p>Theresienstadt \te-'ra-ze-3n-,shtat\ Nazi concentration camp in World  War II. Originally a town in northern Bohemia (now in the Czech Repub�  lic), it became a walled ghetto for Jews in 1941. After the small non-  Jewish population was evacuated in 1942, Jewish captives were shipped  there from Germany, Austria, Czechoslovakia, Denmark, and The Neth�  erlands. Of the approximately 144,000 Jews sent to Theresienstadt, some  33,000 died in the dense crowding of the ghetto, and 88,000 were shipped  on to extermination camps, especially Auschwitz. By the end of World  War II, only 19,000 were alive. After the war, the town was resurrected  under its Czech name, Terezfn.</p><p>thermae \'th9r-me\ Public bathing complex of ancient Rome, designed  for relaxation and social activity as well as bathing. The Romans devel�  oped public baths to a high degree of sophistication and standardization.  They consisted of a large open garden surrounded by subsidiary club  rooms and a main block that contained three large bath chambers�hot  room, steam room, and warm room�and smaller bathrooms, cold room,  and courts for exercise. Imperial thermae, such as the Baths of Caracalla  (ad 216), were immense and opulently furnished. Service was supplied  by slaves moving through underground passageways. Heating was accom�  plished by circulating heated air from a fire under the floor. Lighting of  the enormous rooms was provided by an ingenious system of clerestory  windows.</p><p>thermal conduction Transfer of heat energy resulting from differ�  ences in temperature between adjacent bodies or adjacent parts of a body.  In the absence of a heat pump, the energy will flow from a region of higher  temperature to a region of lower temperature. The transfer of energy  occurs as a result of collision among the particles of the matter involved.  The rate of transfer of energy is proportional to the cross-sectional area  of contact and to the difference in temperature between the two regions.  A substance of high thermal conductivity, such as copper, is a good ther�  mal conductor; one with low thermal conductivity, such as wood, is a  poor thermal conductor. See also convection, radiation.</p><p>thermal energy Internal energy of a system in thermodynamic equi�  librium (see thermodynamics) by virtue of its temperature. A hot body has  more thermal energy than a similar cold body, but a large tub of cold water  may have more thermal energy than a cup of boiling water. Thermal  energy can be transferred from one body, usually hotter, to a second body,  usually colder, in three ways: conduction (see thermal conduction), con�  vection, and RADIATION.</p><p>thermal expansion Increase in volume of a material as its tempera�  ture is increased, usually expressed as a fractional change in dimensions  per unit temperature change. When the material is a solid, thermal expan�  sion is usually described in terms of change in length, height, or thick�  ness. If a crystalline solid has the same structural configuration  throughout, the expansion will be uniform in all dimensions. Otherwise,  there may be different expansion coefficients and the solid will change  shape as the temperature increases. If the material is a fluid, it is more  useful to describe the expansion in terms of a change in volume. Because  the bonding forces among atoms and molecules vary from material to  material, expansion coefficients are characteristic of elements and com�  pounds.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1898 I thermal radiation &#x25BA; Thespis</p><p>thermal radiation Process by which energy is emitted by a warm  surface. The energy is electromagnetic radiation and so travels at the speed  of light and does not require a medium to carry it. Thermal radiation  ranges in frequency from infrared rays through visible light to ultraviolet  rays. The intensity and frequency distribution of the emitted rays are  determined by the nature and temperature of the emitting surface; in gen�  eral, the hotter the object, the shorter the wavelength. A hotter object is a  better emitter than a cooler one, and a blackened surface is a better emit�  ter than a silvered one. An example of thermal radiation is the heating of  the Earth by the Sun.</p><p>thermal spring See hot spring</p><p>Thermidorian Reaction (1794) Revolt in the French Revolution  against the Reign of Terror that was initiated on 9 Thermidor (July 27).  Weary of the mounting executions (1,300 in June alone), deputies in the  National Convention decreed the arrest of Maximilien Robespierre, Louis de  Saint-Just, and other members of the Committee of Public Safety. They and  others were guillotined, inaugurating a brief �White Terror� against the  radical Jacobin Club. The Directory period followed soon afterward.</p><p>thermocouple or thermal junction or thermoelectric ther�  mometer Temperature-measuring instrument consisting of two wires  of different metals joined at each end. One junction is placed where the  temperature is to be measured, and the other is kept at a constant lower  (reference) temperature. A measuring instrument is connected in the elec�  trical circuit. The temperature difference causes the development of an  electromotive force that is approximately proportional to the difference  between the temperatures of the two junctions. Temperature can be read  from standard tables, or the instrument can be calibrated to display tem�  perature directly.</p><p>thermodynamics Study of the relationships among heat, work, tem�  perature, and energy. Any physical system will spontaneously approach an  equilibrium that can be described by specifying its properties, such as pres�  sure, temperature, or chemical composition. If external constraints are  allowed to change, these properties generally change. The three laws of  thermodynamics describe these changes and predict the equilibrium state  of the system. The first law states that whenever energy is converted from  one form to another, the total quantity of energy remains the same. The  second law states that, in a closed system, the entropy of the system does  not decrease. The third law states that, as a system approaches absolute  zero, further extraction of energy becomes more and more difficult, even�  tually becoming theoretically impossible.</p><p>thermoluminescence Emission of light from certain heated sub�  stances as a result of previous exposure to high-energy radiation. The  radiation causes displacement of electrons within the crystal lattice of the  substance. Upon heating, the trapped electrons return to their normal,  lower-energy positions, releasing energy in the process. The longer the  substance is exposed to radiation, the greater is the energy released. By  measuring the amount of light given off, the duration of exposure to  radiation can be determined; thus, thermoluminescence has been used to  determine the age of various minerals and archaeological artifacts.</p><p>thermometry Uhor-'ma-mo-treX Science of measuring the temperature  of a system or the ability of a system to transfer heat to another system.  Temperature measurement is important to a wide range of activities,  including manufacturing, scientific research, and medicine.</p><p>thermonuclear bomb See hydrogen bomb  thermonuclear weapon See nuclear weapon</p><p>Thermopylae Uhor-'ma-po-leV, Battle of Battle in northern Greece  (480 bc) in the Persian Wars. The Greek forces, mostly Spartan, were led  by Leonidas. After three days of holding their own against the Persian king  Xerxes I and his vast southward-advancing army, the Greeks were betrayed,  and the Persians were able to outflank them. Sending the main army in  retreat, Leonidas and a small contingent remained behind to resist the  advance and were killed to the last man.</p><p>thermoreception Sensory capacity (see sense) to detect the tempera�  ture of the environment and the body. It helps keep body temperature  stable by regulating autonomic responses to temperature changes (see  homeostasis). Temperature sensations are generated by separate heat and  cold receptors (nerve endings) in the skin. Blood-sucking insects and  some snakes (e.g., the pit viper) locate prey by its thermal radiation.</p><p>thermostat Device that detects temperature changes for the purpose of  maintaining the temperature of an enclosed area essentially constant. The  thermostat generates signals, usually electrical, to activate relays, valves,  switches, and so on when the temperature rises above or falls below the  desired value. Thermostats are used to control the flow of fuel to a burner,  of electric current to a heating or cooling unit, or of a heated or cooled  gas or liquid into the area it serves. They are also used in fire-detection  warning systems.</p><p>theropod Vthir-s-.padX Any species of bipedal, carnivorous saurischian  in the suborder Theropoda. The chicken-sized Compsognathus,the small�  est known adult dinosaur, probably weighed 2-4 lb (1-2 kg); the tyran-  nosaurs weighed tons. The theropods also included Allosaurus,  Deinonychus, Megalosaurus, Oviraptor, and Velociraptor. Theropod  remains recovered have been from the Late Triassic through the Late Cre�  taceous Epoch (227-65 million years ago) from all continents except Ant�  arctica. Their well-developed hind legs provided support and locomotion;  their short forelimbs had mobile hands, probably for grasping and tear�  ing prey. Despite the group�s name, which means �beast (i.e., mammal)  foot,� theropod feet usually resembled those of birds. It is widely believed  that all modern birds are descended from one line of small theropods.</p><p>Theseum \thi-'se-9m\ Temple in Athens dedicated to Hephaestus and  Athena as patrons of the arts and crafts. Built c. 450 bc, it is slightly older  than the Parthenon. Some of its sculptures represent the exploits of The�  seus (the source of its traditional name), though reconstructed fragments  of its ornamentation reveal that its theme was actually the apotheosis of  Heracles. It is surrounded by a single row of Doric columns, with 13 at  the sides and six at the ends. It is the world�s best-preserved ancient Greek  temple, largely because of its medieval conversion to a Christian church.</p><p>Theseus Vthe-se-ss, 'thes-,yus\ Hero of ancient Greek legend. He was  the son of Aegeus, king of Athens.</p><p>On his journey to Athens, he slew  many legendary villains, including  Sinis, Sciron, and Procrustes. In Ath�  ens he found Aegeus married to  Medea; she recognized him before  her husband did and tried to poison  him but failed, and Aegeus declared  him heir to the throne. In Crete The�  seus met Ariadne and slew the Mino�  taur; on returning to Athens, he  forgot to replace the ship�s black sail  with a white one signaling his vic�  tory, and Aegeus threw himself from  the Acropolis in grief. Theseus went  on to unite and extend the borders of  Attica. He captured the Amazon prin�  cess Antiope (Hippolyte), with the  result that the Amazons attacked  Athens and Antiope was killed while  defending it. He abducted the child  Helen and attempted to steal Persephone from Hades, but he was confined  in the underworld until his rescue by Heracles.

The uneaten, rotted remains were brought up and laid on  an altar; if mixed with seeds they were believed to ensure a good crop.</p><p>Thespiae \'thes-pe-,e\ Ancient town, Boeotia, eastern central Greece. It  was the site of temples and festivals of the Muses and of Praxiteles' famous  statue of Eros. It is important in Greek history chiefly as an enemy of  nearby Thebes.

Founded in 316 bc, it  became the capital of the Roman province of Macedonia in 146 bc and  grew to great importance. The apostle Paul (see St. Paul) visited c. ad  49-50, and he later addressed epistles to converts there. During the time  of the Byzantine Empire, it prospered despite repeated attacks by Avars  and Slavs. It was part of the Ottoman Empire from 1430 to 1912. Thes�  saloniki was the headquarters of the Young Turk movement in 1908 and  was returned to Greece in 1913. It was an important Allied base in World  War I and was occupied by the Germans in World War II. It is Greece�s  second largest city.</p><p>Thessaly Vthe-S9-Ie\ Historical region and current administrative region  (pop., 2001: 754,893), east-central Greece. The ancient region corre�  sponded roughly to the modern one. Mount Olympus rises in the northeast.  Thessaly is drained by the Pinios River. It was the site of many cultures in  the 3rd-2nd millennia bc; by c. 1000 bc Greeks had established power  there. Incorporated into the Roman province of Macedon in the 2nd cen�  tury bc, it was made a separate Roman province in the 4th century ad. In  the 7th�13th centuries it was controlled by Slavs, Saracens, Bulgars, and  Normans. In the late 14th century it passed to the Turks; it was returned  to Greece in 1881. It saw heavy fighting between Allied and Axis forces  in 1941.</p><p>Thetis \'the-tas\ In Greek mythology, a Nereid loved by both Zeus and  Poseidon. When it was revealed that Thetis was destined to bear a son  who would be mightier than his father, the two gods gave her to Peleus,  king of the Myrmidons. Unwilling to wed a mortal, Thetis resisted Peleus�  advances by changing into various shapes, but Peleus finally captured and  married her. Their child was Achilles. Some legends relate that she bore  seven children, all of whom perished either when she tried to render them  immortal or when she killed them as the offspring of a forced marriage.</p><p>thiamin Vthl-o-moM or vitamin B| Organic compound, part of the  vitamin B complex, necessary in carbohydrate metabolism.

Sept. 3, 1877, Saint-Germain-en-Laye, near Paris) French  politician and historian. He went to Paris in 1821 as a journalist and  cofounded the opposition newspaper National in 1830. In the July Revo�  lution he supported Louis- Philippe and served as minister of the interior  (1832, 1834-36) and premier and foreign minister (1836, 1840). A leader  of the conservative moderates, he crushed all insurrections. Following the  February Revolution, he helped elect Louis-Napoleon (later Napoleon III)  president of the Second Republic. As a leader of the opposition (1863-70),  he attacked Napoleon Ill�s imperial policies. As president of the Third  Republic (1871-73), he negotiated the end of the Franco-Prussian War and  restored domestic order by crushing the Paris Commune. He also wrote  major historical works, most importantly the huge History of the French  Revolution (10 vol., 1823-27) and History of the Consulate and the  Empire (20 vol., 1845-62).</p><p>Thimann Vthl-monV, Kenneth V(ivian) (b.

In  1934 he obtained and isolated pure auxin, an important plant-growth hor�  mone and, with several coworkers, proved that auxin promotes cell elon�  gation, formation of roots, and growth of buds, discoveries that led to the  development of a widely used synthetic auxin, 2,4-D. Use of this and simi�  lar chemicals can prevent the premature falling of fruit and stimulate cut  stems to grow abundant roots; because high concentrations of auxins are  toxic to most plants, synthetic auxins are also effective weed killers.</p><p>Thimphu \thim-'pu\ Town (pop., 1999 est.: 28,000), capital of Bhutan.

Solutions of the mixtures to  be analyzed are spotted near one edge. Solutions of reference compounds  are similarly applied. The edge of the plate is then dipped in a solvent.  The solvent travels up the matrix by capillarity, moving the components  of the samples at various rates because of their different degrees of attach�  ment to the matrix and solubility in the developing solvent. The compo�  nents, visible as separated spots, are identified by comparing the distances  they have traveled with those of the known reference materials. TLC is  useful for biological mixtures, especially lipids in animal or vegetable tis�  sues and isoprenoids and essential oils found in flowers and other parts of  plants. The matrices withstand strong solvents and developers better than  the paper used in paper chromatography.</p><p>think tank Institute, corporation, or group organized for interdiscipli�  nary research, usually conducted for governmental and commercial cli�  ents.

Theories of thought and thought  processes have concentrated largely on directed thinking, including prob�  lem solving. At the beginning of the 20th century, researchers focused on  studying mental associations. Theorists of Gestalt psychology in the 1920s  and �30s believed the elements of thought to be in the nature of patterns  elicited from experience. Today these elements are often regarded as bits  of information undergoing processing.

The remaining half of an exploded volcano, it  surrounds a lagoon with volcanic cliffs rising to almost 1,000 ft (300 m). It  was settled in the Bronze Age; Minoan remains date to before 2000 bc. One  of the largest known volcanic eruptions occurred on the island c. 1500 bc,  depositing ash and pumice as far away as Egypt and Israel. The eruption  has been linked to such phenomena as the miracles of the Exodus and the  sinking of Atlantis. Excavations have revealed a rich Minoan city buried  under the volcanic debris. It was resettled by Dorian invaders c. 1000 bc.</p><p>Third Estate French Tiers Etat In French history, one of the three  orders (with the nobility and the clergy) of the Estates-General before the  French Revolution.

After the fall of the  Second Empire and the suppression of the Paris Commune, the new Consti�  tutional Laws of 1875 were adopted, establishing a regime based on par�  liamentary supremacy. Despite its series of short-lived governments, the  Third Republic was marked by social stability (except for the Alfred Drey�  fus affair), industrialization, and establishment of a professional civil ser�  vice. It ended with the fall of France to the Germans in 1940. Presidents  of the Third Republic included Adolphe Thiers (1871-73), Maurice de Mac-  Mahon (1873-79), Jules Grevy (1879-87), Sadi Carnot (1887-94), Felix  Faure (1895-99), Emile Loubet (1899-1906), Armand Fallieres (1906-  13), Raymond Poincare (1913-20), Alexandre Millerand (1920-24), Gaston  Doumergue (1924-31), and Albert Lebrun (1932-40).

Designed and headed  (1826-44) by Count Aleksandr Benckendorff (1783-1844), it gathered  information on political dissidents and banished suspected political crimi�  nals to remote regions. It collaborated with the Corps of Gendarmes  (formed in 1836), a military force that operated throughout Russia, and  with a network of spies and informers. The department grew increasingly  repressive, and in the 1870s it arrested many Narodniks (Populists) who  agitated among the peasantry. It was abolished in 1880, and its functions  were transferred to the police of the interior ministry.</p><p>third world Political designation originally used (1963) to describe  those states not part of the first world�the capitalist, economically devel�  oped states led by the U.S.�or the second world�the communist states  led by the Soviet Union.

With  the end of the Cold War and the increased economic competitiveness of  some developing countries, the term has lost its analytic clarity.</p><p>Thirteen Articles of Faith or Thirteen Principles of Faith Sum�  mary of the basic tenets of Judaism. It was formulated by Moses Maimonides  in his commentary on the Mishna, in an effort to put forth true concepts  of God and faith as a tool in avoiding error. Though presented as dogma,  his statement was a personal concept and has been much debated and  revised. The articles state various doctrines concerning the nature of God,  the law, and Moses, and they affirm that the Messiah is coming and that the  dead will rise. All versions include the hymn �Yigdal,� which is part of  most Jewish prayer services.</p><p>Thirty Tyrants (404�403 bc) SpARTAN-imposed oligarchy that ruled Ath�  ens after the Peloponnesian War. Thirty commissioners were appointed to  the oligarchy, which had an extremist conservative core, led by Critias.  Their oppressive regime fostered a bloody purge, in which perhaps 1,500  residents were killed. Many moderates fled the city; gathering a force,  they returned to defeat the tyrants� forces in a battle at Piraeus in 403.  The 30 fled and were killed off over the next few years.</p><p>Thirty Years'War (1618-48) Series of intermittent conflicts in Europe  fought for various reasons, including religious, dynastic, territorial, and  commercial rivalries. The overall war was mainly a struggle between the  Habsburg-controlled Holy Roman Empire and the Protestant principali�  ties that relied on the chief anti-Catholic powers of Sweden and the Neth�  erlands. It also involved the rivalry of France with the Habsburg powers,  which formed anti-French alliances. The conflicts began in 1618 when  the future Emperor Ferdinand II tried to impose Roman Catholicism on his  domains and the Protestant nobles rebelled; the war was sparked by the  Defenestration of Prague. The battlefield centred on the principalities in  Germany, which suffered severely from plundering armies. Early suc�  cesses by the Catholic League were countered by military gains by Swe�  den. When the bloodshed ended with the Peace of Westphalia (1648), the  balance of power in Europe had been radically changed. France emerged  as the chief Western power, and states of the Holy Roman Empire were  granted full sovereignty, establishing a framework for a modern Europe  of sovereign states.</p><p>Thiruvananthapuram formerly Trivandrum Vtro-'van-dranA Sea�  port (pop., 2001: 744,983), capital of Kerala state, southwestern India.

Its cultural amenities  include the University of Kerala (1937).</p><p>thistle Weedy species of Cirsium, Carduus, Echinops, Sonchus, and  other plant genera of the composite family. The term usually refers to prickly  leaved species of Carduus and Cirsium, which have dense heads of small,  usually pink or purple flowers. Because they have spiny stems and flower  heads without ray flowers, Carduus species are called plumeless thistles.  Canadian thistle ( Cirsium arvense) is an attractive but troublesome weed  in agricultural areas of North America. The thistle is the national emblem  of Scotland.</p><p>Thjorsa River Vthy6r-,sau\ River, Iceland.

John Danforth (1979-81), assistant  secretary in the U.S. Department of Education (1981-82), and chairman of  the Equal Employment Opportunity Commission (EEOC) (1982-90).  Pres. George Bush appointed him to the U.S. Court of Appeals in 1990 and  then to the Supreme Court of the United States; he thereby became the sec�  ond African American justice on the court, after Thurgood Marshall. His  1991 confirmation hearings attracted enormous public interest and media  attention, largely because of accusations of sexual harassment by Anita Hill,  a law professor and former colleague of Thomas at the EEOC. Thomas  denied the charges, and the Senate narrowly voted to confirm him. A quiet  presence on the court, he generally follows a predictable pattern in his  opinions�conservative, restrained, and suspicious of the reach of the fed�  eral government into the realm of state and local politics.</p><p>Thomas, Dylan (Marlais) (b.

In 1387 he entered the Augustinian monastery of  canons regular at Agnietenberg. He was ordained a priest in 1413 and  devoted himself to copying manuscripts and directing novices. He is cred�  ited with writing The Imitation of Christ, the most influential devotional  work in Christian literature after the Bible. Noted for its simple language  and style, it emphasizes spiritual over materialistic life and affirms the  rewards of a life centred on Christ.

Aug. 4, 1976, London, Eng.)  Canadian-British publisher. Thomson began acquiring radio stations and  newspapers in Ontario in the 1930s; later he expanded his interests to  Britain and the U.S. and added television holdings. In 1952 he bought  The Scotsman newspaper and went to Edinburgh to run it. In 1959 he  purchased the Kemsley group of newspapers, the largest in Britain, which  included the Sunday Times. In 1967 he made his most important purchase,  The Times of London, and thereafter made a major investment in it, pro�  viding it with financial stability. In the 1970s Thomson joined a consor�  tium that was successful in discovering two oil fields. It sold The Times  in 1981 and divested interests in U.K. newspapers in 1995. The acquisi�  tion of various publishing and other interests continued into the 21st cen�  tury, and the Thomson Corp. is today one of the largest publishing  conglomerates in the world.</p><p>Thomson, Virgil (b. Nov. 25, 1896, Kansas City, Mo., U.S.�d. Sept.  30, 1989, New York, N.Y.) U.S. composer and critic. He attended Har�  vard University, intending to become a pianist and organist. Studying in  Paris with Nadia Boulanger (1921), he met the French composers known  as Les Six and their circle and began to compose. While residing in Paris  (1925^10), he met Gertrude Stein, with whom he wrote the operas Four  Saints in Three Acts (1928) and The Mother of Us All (1946), affecting a  charmingly naive style. Back in New York City, he served as music critic  of the Herald Tribune (1940-54); his gracefully written criticism was  respected for its concern with music rather than performers. His other  works include the film scores The Plow That Broke the Plains (1936) and  The Louisiana Story (1949, Pulitzer Prize).</p><p>Thonet \'to-net\, Michael (b. July 2, 1796, Boppard, Trier �d. March  3, 1871, Vienna, Austria) German Austrian pioneer in the industrializa�  tion of furniture manufacture. He developed a system of steam-bent  veneers c. 1830 and created light, curvilinear chairs. By 1856 he had per�  fected the bending of solid beechwood with heat and began mass pro�  duction of bentwood furniture. He set up factories in Hungary and Moravia  and opened salons from Moscow to Chicago. By 1870 he was producing  furniture in hitherto unheard-of quantities. His furniture is still being  manufactured today.</p><p>Thor Deity, common to all the early  as a great, red-bearded warrior of tre�  mendous strength. The son of Odin  ( according to some legends) and  Jord, the earth goddess, he was the  implacable foe of the harmful race of  giants but was benevolent toward  humans. His name is the Germanic  word for thunder. His great weapon  was his hammer, Mjollnir. His great�  est enemy was the world serpent Jor-  mungand, which he was destined to  kill, and be killed by, in the Rag-  narok.

Back in  Concord, he came under the influ�  ence of Ralph Waldo Emerson and  began to publish pieces in the Tran-  scendentalist magazine The Dial. In  the years 1845-47, to demonstrate  how satisfying a simple life could be,  he lived in a hut beside Concord�s  Walden Pond; essays recording his  daily life were assembled for his  masterwork, Walden (1854). His A  Week on the Concord and Merrimack  Rivers (1849) was the only other  book he published in his lifetime. He  reflected on a night he spent in jail  protesting the Mexican-American  War in the essay �Civil Disobedi�  ence� (1849), which would later  influence such figures as Mohandas  K. Gandhi and Martin Luther King, Jr. In later years his interest in Tran�  scendentalism waned, and he became a dedicated abolitionist. His many  nature writings and records of his wanderings in Canada, Maine, and Cape  Cod display the mind of a keen naturalist. After his death his collected  writings were published in 20 volumes, and further writings have contin�  ued to appear in print.</p><p>Thorez \to-'rez\, Maurice (b.

He joined the  French Communist Party c. 1920 and was arrested several times for agita�  tion. After becoming local party secretary (1923), he rose to secretary-  general of the party (1930). He served in the Chamber of Deputies (1932-  39, 1945-60) and helped form the Popular Front government in 1936. He  lived in the Soviet Union (1943-44), then returned to France and served  as a minister of state (1945) and deputy premier (1946, 1947). He  remained a dedicated Stalinist even after Nikita Khrushchev denounced  Joseph Stalin in 1956.</p><p>thorium Metallic chemical element, chemical symbol Th, atomic num�  ber 90. One of the actinide series of elements, natural thorium is a mix�  ture of radioactive isotopes, predominantly thorium-232 (half-life of more  than 10 billion years). It is a dense metal that is silver-white in pure form  but turns gray or black on prolonged exposure to air. Although not a  nuclear reactor fuel itself, thorium-232 can be used in breeder reactors  because, on capturing slow-moving neutrons, it decays into fissionable  uranium-233. Thorium is added to magnesium and its alloys to improve  their high-temperature strength. Added to glass, it yields glasses with a  high refractive index, useful for specialized optical applications. It was  formerly in great demand as a component of mantles for gas and kero�  sene lamps and has been used in the manufacture of tungsten filaments  for lightbulbs and vacuum tubes.</p><p>Thorndike, Edward L(ee) (b.

He trained  under William James and James McKeen Cattell and later taught at Colum�  bia University (1904^-0). A pioneer in the fields of animal learning and  educational psychology, he developed a form of behaviourism known as  connectionism, which holds that learning takes place through associative  bonds. He contributed significantly to the development of quantitative  experimental methods and to more efficient and scientifically based meth�  ods of teaching. Among his writings are Introduction to the Theory of  Mental and Social Measurements (1904), Principles of Teaching Based  on Psychology (1906), Animal Intelligence (1911), and The Psychology  of Wants, Interests, and Attitudes (1935).</p><p>s</p><p>u</p><p>Germanic peoples, who appeared</p><p>Thor with his hammer, Mjollnir, on his  knees, bronze statuette from northern  Iceland, c. ad 1000; in the National  Museum of Iceland, Reykjavik.</p><p>COURTESY OF THE NATIONAL MUSEUM OF ICELAND,  REYKJAVIK</p><p>Henry David Thoreau, portrait by Sam�  uel Worcester Rowse, 1854; in the  Concord Free Public Library, Massa�  chusetts.</p><p>COURTESY OF THE CORPORATION OF THE FREE PUBUC  LIBRARY, CONCORD, MASS.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Thorndike &#x25BA; thread cross I 1903</p><p>Thorndike, Dame (Agnes) Sybil (b.

He  was the inventor of writing, the creator of languages, the representative  of Re, and the scribe, interpreter, and adviser of the gods. In the myth of  Osiris, Thoth protected the pregnant Isis and healed the eye of her son  Horus. He judged the deceased and reported the results to Osiris. His  sacred animals were the ibis and the baboon, millions of which were mum�  mified in his honour. He was often represented in human form with the  head of an ibis. The Greeks identified Thoth with Hermes; as Hermes Tris-  megistos he was regarded as the author of the Hermetic writings.</p><p>thought, laws of Traditionally, the three fundamental laws of logic:  (1) the law of contradiction, (2) the law of excluded middle (or third), and  (3) the principle of identity.

The frame story, in which the  vengeful King Shahryar�s plan to marry and execute a new wife each day  is foiled by the resourceful Scheherazade, is probably Indian; the tales  with which Scheherazade beguiles Shahryar, postponing and eventually  averting her execution, come from India, Iran, Iraq, Egypt, Turkey, and  possibly Greece. It is now believed that the collection is a composite work  originally transmitted orally and developed over a period of several cen�  turies.

The Thousand Islands International Bridge,  which contains five spans linking some of the islands and is 8.5 mi (13.7  km) long, connects New York and Ontario.</p><p>Thrace Ancient and modem region, southeastern Balkan Peninsula. Its  borders have varied at different periods. In ancient Greek times it was  bounded by the Danube River, the Aegean Sea, and the Black Sea. Modem  Thrace corresponds to southern Bulgaria, the Greek province of Thrace,  and European Turkey, including the Gallipoli peninsula. The Thracians  were Indo-Europeans who settled in the region in the 2nd millennium bc;  their culture was noted for its poetry and music, and their soldiers were  known as superior fighters. Later colonized by Greeks in the 7th century  bc, it became subject to Persia in the 6th century bc and to Macedon in  the 4th century bc. Reduced to a Roman province in the 1st century ad,  its northern part was annexed to Moesia. It later became part of the Byz�  antine empire, and in 1453 part of the Ottoman empire. The northern part  was annexed by Bulgaria in 1885; the eastern part passed to Turkey in  1923. The region harvests com, rice, grapes, oysters, and eels; the chief  cash crop is Turkish tobacco.</p><p>thrasher Any of 17 species (family Mimidae) of New World songbirds  that have a downcurved bill and are  noted for noisily foraging on the  ground in dense thickets and for  loud, varied songs. Thrashers occur  from northern Canada to central  Mexico and the Caribbean. The  brown thrasher ( Toxostoma rufum),  of North America east of the Rocky  Mountains, is about 12 in. (30 cm)  long and has red-brown plumage  with streaked underparts. Long�  tailed drab species are found in the  arid southwestern U.S. and in  Mexico.</p><p>thread Tightly twisted yarn con�  sisting of several strands that has a  circular cross-section and is used in  commercial and home sewing machines and for hand sewing. Thread is  usually wound on spools, with thread size (degree of fineness) indicated  on the spool end. Cotton thread can be used with fabrics made from yarn  of plant origin, such as cotton and linen, and with rayon (made from cel�  lulose, a plant substance). Silk thread is suitable for silks and wools, both  of animal origin. Nylon and polyester threads are appropriate for synthet�  ics and for knits with a high degree of stretch.</p><p>thread cross Object made typically of two sticks bound together in the  shape of a cross, with coloured threads wound around their ends to  resemble a cobweb, used in Tibetan magical rituals to entrap evil spirits.  Similar devices have been found in South Africa, Peru, Australia, and  Sweden. They vary from simple diamond shapes to complex wheel- or  box-shaped combinations reaching 11 ft (3 m) high. They are often highly  decorated, with wool, feather, and bits of paper.</p><p>Jim Thorpe demonstrating the drop  kick.</p><p>THE BETTMANN ARCHIVE</p><p>Brown thrasher (Toxostoma rufum).</p><p>THASE DANIEL</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1904 I Three Emperors'League &#x25BA; thrush</p><p>Three Emperors' League German Dreikaiserbund Diplomatic  alignment of the empires of Germany, Austria-Hungary, and Russia  devised by Otto von Bismarck in 1872. Its aim was to neutralize disagree�  ment between Austria-Hungary and Russia over spheres of influence in  the Balkans and to isolate Germany�s enemy France. After the first Three  Emperors� League (1872-78) collapsed, Bismarck succeeded in renew�  ing it (1881, 1884). When Russia declined a third renewal, Bismarck  negotiated a separate accord with Russia, the Reinsurance Treaty (1887).

On completion, scheduled for 2009, it would be the  largest dam in the world, producing a vast quantity of hydroelectricity  from 26 generators. It would also create an immense deepwater reservoir  that would allow 10,000-ton freighters to navigate 1,400 mi (2,250 km)  inland from the East China Sea. The extremely controversial project would  require displacement of more than a million people and destruction of  magnificent scenery and archaeological sites. Critics also fear potential  pollution and silting of the reservoir and the possibility of the dam�s col�  lapse. Though construction began in 1993, a third of the National Peo�  ple�s Congress either abstained or opposed it, and the World Bank would  not advance funds, citing environmental and other concerns. Critics have  contended that smaller dams on Yangtze tributaries could accomplish the  same purpose with fewer risks.</p><p>Three Henrys, War of the (1587-89) Last of the Wars of Religion  in France, fought between King Henry III, the ultra-Catholic Henri I de  Lorraine, duke de Guise, and the Huguenot leader Henry of Navarra (later  Henry IV). Early conflicts were won by the Holy League led by Guise, who  forced Henry III to sign the Edict of Union in 1588, naming him lieuten�  ant general of the kingdom. Humiliated, Henry III had Guise assassinated,  but the Holy League continued to wield power, and Henry called for help  from his cousin, Henry of Navarra. The royalist-Huguenot coalition  forced the Holy Leaguers to retreat, but Henry III was assassinated, and,  before he died, he exhorted the future Henry IV to become a Roman  Catholic.</p><p>Three Kingdoms (ad 220-80) Trio of warring Chinese states that fol�  lowed the demise of the Han dynasty. Cao Cao put his son on the throne  of the kingdom of Wei, which controlled northern China. The kingdom  of Shu-Han was established in present-day Sichuan by Liu Bei and his  adviser Zhuge Liang, and the kingdom of Wu was established in the south,  with its capital at Nanjing. They were all subsumed into the Jin dynasty  by ad 280. The 60 years of the Three Kingdoms have inspired Chinese  literature, and especially historical fiction, ever since.</p><p>Three Mile Island Nuclear power station near Harrisburg, Pa., site of  the most serious accident in the history of the U.S. nuclear power industry  (March 28, 1979). Mechanical failures and human errors caused a partial  meltdown of the nuclear core and the release of radioactive gases. Despite  assurances that there had been little risk to people�s health, the accident  increased public fears about the safety of nuclear power and strengthened  public opposition to its use, effectively stopping construction of nuclear  reactors and further development of U.S. nuclear power plants.</p><p>Three Stooges U.S. comedy team. It was originally formed as a vaude�  ville team in 1923 by brothers Moe and Shemp Howard (1897-1975,  1900-55), who performed with �Ted Healy and His Stooges.� In 1928 the  brothers added Larry Fine (1911-74) to the act, which appeared in Broad�  way revues. After Shemp left the act (1930), he was replaced by his brother  Curly (1906-52). They appeared in several feature films, and in 1934 they  began a series of comedy shorts that numbered more than 200 when they  ceased in 1958. Their films were characterized by violent slapstick.</p><p>3M Co. U.S. corporation headquartered in St. Paul, Minn., manufactur�  ing a wide range of products. It was incorporated as Minnesota Mining  and Manufacturing Co. in 1902; its first product was sandpaper. It grew  steadily, adding the original cellophane tape, Scotch tape, as well as mask�  ing tape to its product line. Other innovations included the widely used  Post-it notes, introduced in 1980. 3M�s products include photographic  film, videocassettes, computer-synthesized graphics, and health-care  products. It is notable among diversified U.S. corporations in that its  growth has been primarily by internal means rather than by large-scale  acquisitions.</p><p>threonine Vthre-3-,nen\ One of the essential amino acids.

They are found in tropical and temperate seas worldwide. They eat squid  and schooling fishes, attacking after circling and herding their prey into  small groups. They sometimes use their tail to stun their prey or, by  thrashing the water, to frighten them. They are not considered dangerous  to humans. The long-tailed thresher, or fox shark (Alopias vulpinus), is a  big, dark fish that grows about 20 ft (6 m) long.</p><p>thrips Any of some 5,000 species (order Thysanoptera) of tiny winged  insects that feed chiefly on plants, inhabiting temperate and tropical areas  worldwide. Many species damage cultivated plants, by either sucking the  sap or transmitting viral plant diseases. A few species are predators. Thrips  reach a maximum length of about half an inch (15 mm). Most have two  pairs of long, narrow, hair-fringed wings.</p><p>thrombocyte See platelet</p><p>thrombosis \thram-'bo-s9s\ Formation of a blood clot (thrombus) in  the heart or a blood vessel. Contributing factors include injury to a blood  vessel�s lining from inflammation (thrombophlebitis) or atherosclerosis,  blood flow that is turbulent (e.g., from an aneurysm) or sluggish (e.g., from  prolonged bed rest), or coagulation abnormalities (e.g., from high num�  bers of platelets or excessive fats in the blood). Thrombosis, especially in  deep veins of the leg, is a particular danger after major surgery. A throm�  bus can block blood flow at the point of clot formation or break free to  block it elsewhere (embolism).</p><p>throne Chair of state set on a dais and often surmounted by a canopy,  representing the power of the digni�  tary who sits on it and sometimes  conferring that power. In Greek his�  tory, thrones were identified as seats  of the gods; soon the meaning of the  word included the symbolic seats of  those who held religious or secular  power, a meaning common to virtu�  ally all cultures. The oldest surviving  throne was built into the walls of  Knossos (c. 1800 bc). Probably the  most magnificent was the jewel-  studded Peacock Throne of the rul�  ers of Delhi, stolen from India by  Persia in 1739 and thereafter the  symbol of the Persian/Iranian mon�  archy. In the late 17th and 18th cen�  tury, thrones were often made of  silver, but later versions tend to be of  gilded wood.</p><p>throttle Valve for regulating the  supply of a fluid (as steam) to an  engine, especially the valve control�  ling the volume of vaporized fuel  delivered to the cylinders of an internal-combustion engine. In an automo�  bile engine, gasoline is held in a chamber above the carburetor. Air flows  down through the throat of the carburetor, past the throttle valve, and into  the intake manifold. A throat is formed by the reduced diameter, and  acceleration of the air through this smaller passage causes a decrease in  pressure related to the amount of air flowing. This decrease in throat pres�  sure results in fuel flow from the jet into the airstream. Any increase in  airflow caused by change in engine speed or throttle position increases  the pressure differential acting on the fuel and causes more fuel to flow.  See also venturi tube.</p><p>thrush Any of about 300 species of songbirds (family Turdidae) that usu�  ally have a slender bill and �booted� lower legs (i.e., covered in front with  one long scale instead of many short ones). Thrushes are 5-12 in. (13-30  cm) long. Most have dull plumage, often with patches of bright yellow, red,  or blue. They are found virtually worldwide but are most diverse in the Old  World, especially in Africa. The northern species are strong migrants.  Occupying a wide range of arboreal and terrestrial habitats, thrushes eat  insects and fruit; a few eat snails or earthworms. They lay three to six eggs  in an open cup-shaped nest; a few occupy cavities.

Thunderstorms have  been known to occur in almost every  part of the world, although they are rare in the polar regions. In the U.S.  the areas of maximum thunderstorm activity are the Florida peninsula and  the coast of the Gulf of Mexico (70-80 days per year).</p><p>Thunen Vtue-nonV, Johann Heinrich von (b. June 24, 1783, Jever,  Oldenburg�d. Sept. 22, 1850, Tellow, Mecklenburg) German economist  and agriculturalist. After carrying out research on his own estate into the  relationship between the costs of commodity transportation and the loca�  tion of production, he set forth his theories in The Isolated State (1826).  He used an imaginary city, isolated in the middle of a fertile plain, to  create a model of concentric zones of agricultural production. Heavy  products and perishables would be produced close to the town, lighter  and durable goods on the periphery; returns on the land would diminish  as transport costs to the city increased. Thunen�s model influenced many  later writers on the subject.</p><p>Thurber, James (Grover) (b. Dec. 8, 1894, Columbus, Ohio,  U.S.�d. Nov. 2, 1961, New York, N.Y.) U.S. writer and cartoonist. He  attended Ohio State University before moving to New York City in 1926.  He was on The New Yorker staff from 1927 to 1933 and thereafter  remained a leading contributor. His drawings illustrated his first book, Is  Sex Necessary? (1929; with E.B. White), and his cartoons became some  of the most popular and recognizable in America. In 1940 his failing eye�  sight forced him to curtail his drawing; by 1952 he had to give it up alto�  gether as his blindness became nearly total. His writings include My Life  and Hard Times (1933), Fables for Our Time (1940), and the children�s  book The 13 Clocks (1950). He is noted for his vision of the befuddled  urban man who, like the hero of his short story �The Secret Life of Walter  Mitty� (1939; film, 1946), escapes into fantasy.</p><p>Thuringia \thu-'rin-je-o\ German Thiiringen Vtui-riq-snX Historic  region and state (pop., 2002 est.: 2,411,000), Germany. It includes the land  around the Thuringian Forest in what was formerly southwestern East  Germany and covers 6,244 sq mi (16,171 sq km). The capital is Erfurt.  The Germanic Thuringians appeared after c. ad 350 and were conquered  by the Huns in the mid-5th century. In 1485 Thuringia became part of  Saxony and was divided into several states; they joined the German  Empire in 1871 and were reunited after World War I. Following the par�  tition of Germany in 1945, the state became part of East Germany; it was  reconstituted as a state of reunified Germany in 1990. The economy is  largely industrial.</p><p>Thurmond, (James) Strom (b. Dec. 5, 1902, Edgefield, S.C.,  U.S.�d. June 26, 2003, Edgefield) U.S. politician and senator (1954�  2003). He served as a South Carolina state senator (1933-38) and circuit  court judge (1938�41). As governor (1947-51), he expanded the state  educational system. At the 1948 Democratic convention Thurmond led  the bolt of Southern delegates who objected to the civil-rights plank in  the party platform; the so-called Dixiecrats nominated Thurmond as their  presidential candidate, and he won 39 electoral votes. In 1954 he was  elected to the U.S. Senate, and in 1964 he switched party affiliation to the  Republican Party. He became the Senate�s longest-serving member in  1997. An arch conservative, he advocated states� rights, opposed civil-  rights legislation, and supported increases in military spending.</p><p>Thurstone, L(ouis) L(eon) (b.

Concerned with the mea�  surement of people�s attitudes and intelligence, he was instrumental in  the development of psychometrics. His principal work, The Vectors of the  Mind (1935; revised as Multiple-Factor Analysis, 1947), presented the  technique of multiple-factor analysis to explain correlations between  results in psychological tests.</p><p>Thutmose \thut-'mo-s9\ III (d. 1426 bc) Egyptian king of the 18th  dynasty (r. 1479-1426 bc), often regarded as the greatest pharaoh of  ancient Egypt. He ascended the throne around the age of 10, but his aunt,  Hatshepsut, ruled first as his regent and then in her own right for the next  20 years. On her death he began military campaigns to reestablish Egyp�  tian supremacy in Syria and Palestine. Later he attacked and defeated the  kingdom of Mitanni, a powerful Mesopotamian rival of Egypt. He sub�  dued the Nubian tribes to the south and employed them in the gold mines  that became the basis of Egypt�s wealth. He consolidated his victories  with more campaigns and established a system whereby native rulers  would pay yearly tribute to Egypt and send their heirs as hostages to  Egypt, where they would be educated at court. At home he enlarged the  temple of Amon at Karnak. His mummy was discovered in 1889 and his  mortuary temple in 1962.</p><p>thyme \'tlm\ Pungent herb {Thymus vulgaris ) of the mint family, native  to southern Europe, the Mediterranean, Asia Minor, and Central Asia, and</p><p>460�d. c. 404 bc) Greatest or</p><p>Thucydides, detail of a Roman bust  after a Greek original; in Holkham  Hall, Norfolk, England</p><p>Wooden thunderbird of the Haida Indi�  ans, northwest coast of North America,  19th century; in the British Museum</p><p>COURTESY OF THE TRUSTEES OF THE BRITISH MUSEUM</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1906 I thymine &#x25BA; Tibbett</p><p>cultivated in North America.

Bees are fond of thyme, and  Sicily�s thyme honey has been  famous for centuries. The essential  oil has antiseptic and anesthetic  properties and is used as an internal  medicine; it is also used in perfumes  and toothpastes.</p><p>thymine \'thl-,men\ Organic com�  pound of the pyrimidine family, often  called a base, consisting of a ring  containing both nitrogen and carbon atoms, and a methyl group. It occurs  in combined form in many important biological molecules, particularly  DNA (where its complementary base is adenine). It or its corresponding  nucleoside or nucleotide may be prepared from DNA by selective tech�  niques of HYDROLYSIS.</p><p>thymus Vthl-mosV Pyramid-shaped lymphoid organ (see lymphoid tissue)  between the breastbone and the heart. Starting at puberty, it shrinks slowly.  It has no lymphatic vessels draining into it and does not filter lymph;  instead, stem cells in its outer cortex develop into different kinds of T cells  (see lymphocytes). Some migrate to the inner medulla and enter the blood�  stream; those that do not may be destroyed to prevent autoimmune reac�  tions. This process is most active during infancy. If a newborn�s thymus  is removed, not enough T cells are produced, the spleen and lymph nodes  have little tissue, and the immune system fails, causing a gradual, fatal  wasting disease. Thymus removal in adults has little effect.</p><p>thyroid gland Endocrine gland in the throat that secretes hormones  vital to metabolism and growth. Secretion of thyroid hormones�mostly  thyroxine (T 4 )�is controlled by thyroid-stimulating hormone (TSH),  released by the pituitary gland when the level of thyroid hormones in the  blood drops below a certain threshold (see endocrine system). These hor�  mones� primary action in adults is to regulate cellular oxygen consump�  tion (metabolic rate). They also lower blood cholesterol and are necessary  for normal growth and development in children. The thyroid also pro�  duces calcitonin, a hormone that stimulates deposition of calcium from  the blood into the bones, balancing the action of parathyroid hormone.  See also goitre; Graves disease; iodine deficiency.</p><p>thyroxine \thl-'rak-,sen\ or l-tetraiodothyronine Vel-.te-tro-I-.o-  do-'thI-r3-,nen\ or T 4 One of the two major hormones (along with the  closely related 1-triiodothyronine, or T 3 ) secreted by the thyroid gland. Its  principal function is to stimulate oxygen consumption and thus metabolism  in all cells and tissues in the body. Thyroxine is formed by the addition  of iodine to the amino acid tyrosine while the latter is in a protein-bound  form. Thyroxine secretion is excessive in hyperthyroidism and deficient  in hypothyroidism.</p><p>Thyssen Vtui-sonV Fritz (b. Nov. 9, 1873, Mulheim, Ger.�d. Feb. 8,  1951, Buenos Aires, Arg.) German industrialist and financial backer of  Adolf Hitler. Thyssen entered the family iron, steel, and coal business and  inherited his father�s fortune and empire in 1926 (see Thyssen Krupp Stahl).  He created a family business trust that came to control more than 75% of  Germany�s ore reserves and employ 200,000 workers. Distressed by the  rise of socialism in Germany, he supported Hitler and helped finance his  rise to chancellor. But Thyssen opposed Hitler�s later policies and fled to  Switzerland in 1939, enabling Hitler to confiscate Thyssen�s fortune  (about $88 million). Thyssen was arrested in France (1941) and impris�  oned by the Nazis. After the war, he was convicted as a �minor Nazi� and  ordered to pay 15% of his property in restitution.</p><p>ThyssenKrupp AG German steel company. The Krupp firm began in  1811 when Friedrich Krupp (1787-1826) founded a steel plant in Essen,  and it remained in family hands for a century and a half. Known for its  high-quality steel and its cannons and other armaments, Krupp prospered  with the rise of the German navy. It enjoyed a monopoly on arms manu�  facturing during World War I; one of its most potent weapons was �Big  Bertha.� After the war, Germany was forbidden to manufacture arms, and  parts of the Krupp works were dismantled, though it remained a vast  industrial empire. Krupp�s factories were central to Germany�s illegal</p><p>rearmament under Adolf Hitler in the 1930s. After World War II, Alfried  Krupp (1907-67) was convicted of war crimes for using slave labour and  ordered to forfeit all his property, but with the outbreak of the Korean  War he was granted amnesty and his property restored. In 1968, after his  son renounced the Krupp name and fortune, the company went public. In  1992 it merged with Hoesch AG to become Fried Krupp AG Hoesch-  Krupp. Thyssen AG originated as a rolling mill founded by August Thys�  sen (1842-1926). It merged with seven other steelworks to become  Vereinigte Stahlwerke AG, but reassumed its own identity in 1953. After  the steel divisions of the rival companies were joined in 1997 to form  Thyssen Krupp Stahl, the remaining segments of each company merged  in 1999, creating ThyssenKrupp AG. Its products include steel, construc�  tion and automotive components, elevators, and engineering services.</p><p>Tiamat \'te-a-,mat\ In Mesopotamian mythology, a primal goddess who  is a personification of salt water and the mother of the gods. When con�  flict between her husband, Apsu, and the other gods resulted in Apsu�s  death, Tiamat waged war on the other divinities, backed by an army of  demons she had created. Her battle with, and defeat at the hands of, Mar-  duk forms the substance of the Babylonian creation epic Enuma elish.  From her body Marduk fashioned the heavens and the earth.</p><p>Tian or T'ien \'tyen\ Chinese "Heaven" In indigenous Chinese reli�  gion, the supreme power reigning over humans and lesser gods. The term  refers to a deity, to impersonal nature, or to both. As a god, Tian is an  impersonal power, in contrast to the supreme ruler Shangdi, but the two  are closely identified and their names are sometimes used synonymously.  In later references, Tian is likened to nature or fate. Scholars generally  agree that Tian was the source of moral law, but they long debated whether  Tian responded to pleas and rewarded and punished human actions or  whether events merely followed Tian�s order and principles.</p><p>Tian Shan See Tien Shan</p><p>Tiananmen \'tyan- , an- , men\ Square One of the largest public squares  in the world, originally designed and built in Beijing in 1651 and enlarged  in 1958.

The municipality, on  the Bo Hai, is bordered by Hebei province and Beijing municipality and has  an area of 4,400 sq mi (11,300 sq km). The city, China�s third largest, lies  at the head of the short Hai River, which flows into the Bo Hai; Tianjin  is connected to the Yangtze River (Chang Jiang) by the Grand Canal. It has  been a major transportation and trading centre since the Yuan dynasty in  the 13th century. It was a garrison town during the Ming dynasty (1368�  1644). The British and French occupied it during the Second Opium War  (1856-60); a treaty signed there in 1858 opened 11 Chinese ports to for�  eign trade. As a treaty port, it developed rapidly. It was the scene of heavy  fighting during the Boxer Rebellion (1900), after which it was placed under  an international commission and its walls razed. It is the leading port in  northern China and the country�s second largest manufacturing centre.  Educational institutions include Tianjin University (1895) and Nankai  University (1919).</p><p>Tianshi Dao See Five Pecks of Rice</p><p>Tiantai \'tyan-'dl\ Japanese Tendai \'ten-'dl\ Buddhist sect founded by  Zhiyi in the 6th century ad.

Located on Lake Tiberias (Sea  of Galilee), at 689 ft (210 m) below sea level, it is one of the lowest-lying  towns in the world. It was founded c. ad 20 by Herod Antipas and named  for the Roman emperor Tiberius. After the destruction of Jerusalem by the  Romans in ad 70, it became a centre of Jewish learning and later the seat  of the Sanhedrin and rabbinical schools. The Talmud was edited there in  the 3rd-6th centuries. Saladin took the town from the Crusaders in 1187.  The modern town was refounded under the British mandate in 1922 and  became part of independent Israel in 1948. Historic sites include the tomb  of the great Jewish scholar Moses Maimonides. Along with Hebron, Jerus�  alem, and Zefat, it is one of the four holy cities of Judaism.</p><p>Tiberius in full Tiberius (Julius) Caesar Augustus orig. Tibe�  rius Claudius Nero (b. Nov. 16,</p><p>42 bc �d. March 16, ad 37, Capreae,  near Naples) Second Roman  emperor (ad 14-37). He was raised  by Augustus, who had married his  mother, Livia Drusilla. In his first  military command, at age 22, he  recovered Roman legionary stan�  dards lost for decades in Parthia and  returned to great acclaim. He was  forced to give up his beloved wife to  marry Augustus�s daughter Julia (12  bc). Despite becoming tribune, he  went into self-imposed exile on  Rhodes (6 bc), becoming an angry  recluse. By 4 bc Julia was exiled for  promiscuity by Augustus, who  recalled Tiberius and named him his  heir. As emperor he initially ran the  state efficiently and instituted some  reforms, with only occasional sever�  ity, such as exiling Rome�s Jewish  population on a pretext. When his  son Drusus died mysteriously, he  gave his trust to Sejanus and was per�  suaded to move to Capri (27). He  became increasingly violent, killing  and torturing at a whim. After Seja�  nus became coconsul in 31, Tiberius  became suspicious of his ambition  and executed him, then named Caligula his heir. In 37 the Praetorian Guard  declared its support for Caligula and killed Tiberius when he was on his  sickbed.</p><p>Tiberias, Lake or Sea of Galilee Freshwater lake, northern Israel. It  is 13 mi (21 km) long and 7 mi (11 km) wide; it lies about 700 ft (212 m)  below sea level and receives most of its inflow from the Jordan River. The  region has been inhabited for millennia: archaeological finds dating to  some 500,000 years ago are among the oldest in the Middle East. In the 1st  century ad, the region was rich and populated; Christians know it as the  scene of many episodes in the life of Jesus. Today the lake�s waters irrigate  the surrounding agricultural region. Modern health resorts have grown up,  and the baths at Tiberias are among Israel�s winter resort attractions.</p><p>Tibet \ti-'bet\ Tibetan Bod Vbod\ Chinese Xizang \'she-'dzaq\ or Hsi-  tsang Autonomous region (pop., 2002 est.: 2,670,000), western China.

It has an area of 471,700 sq mi (1,221,600 sq km),  and its capital is Lhasa. Before the 1950s it was a unique entity, with its  own Buddhist culture and religion, that sought isolation from the rest of  the world. Situated on a plateau averaging 15,000 ft (4,500 m) above sea  level, it is the highest region in the world. Its surrounding mountain ranges  include the Kunlun Mountains and the Himalayas; Mount Everest rises on  its border with Nepal. Tibet emerged as a powerful Buddhist kingdom in  the 7th-9th century ad. It came under the control of the Mongols in the  13th century and the Qing (Manchu) dynasty in the 18th century. After the  1911-12 Chinese revolution it gained a measure of autonomy. The Chi�  nese People�s Liberation Army entered Tibet in 1950, and Chinese author�  ity was subsequently established over the region. The 14th Dalai Lama,  Bstan-�dzin-rgya-mtsho, led an abortive rebellion in 1959, after which he  fled to India and set up a government-in-exile. The Tibet Autonomous  Region was established in 1965. Many of Tibet�s cultural treasures were  destroyed or badly damaged during the Cultural Revolution, but restora�  tion work has been underway since then.</p><p>Tibetan Buddhism Form of Mahayana Buddhism that evolved from the  7th century in Tibet. Based on Madhyamika and Yogacara philosophies, it  incorporates the rituals of Vajrayana, the monastic disciplines of early  Theravada, and the shamanistic features of Bon. The predominant Tibetan  sect for the past three centuries has been Dge-lugs-pa. Its spiritual head is  the Dalai Lama. The Tibetan canon is divided into the Bka �gyur (�Trans�  lation of the Word�), consisting of canonical texts translated mostly from  Sanskrit, and Bstan- �gyur (�Transmitted Word�), consisting of commen�  taries by Indian masters. After the Chinese communist takeover in 1959,  Tibetans began a massive emigration that has spread Tibetan Buddhism  around the globe.</p><p>Tibetan language Sino-Tibetan language spoken by more than five  million people in Tibet (Xizang), Qinghai, Sichuan, and Gansu provinces  in China; Bhutan; northern Nepal; and the Kashmir region of India and  Pakistan. Since the occupation of Tibet by China in 1959, enclaves of  Tibetan speakers have dispersed to India and other parts of the world.  Spoken Tibetan comprises a very diverse range of dialects, convention�  ally divided into several groups: Western, including Balti and Ladakhi in  Jammu and Kashmir; Central, including the speech of Lhasa and most of  the Nepalese dialects (including Sherpa); Southern, including the dialects  of Sikkim and Bhutan; Khams, or Southeastern, including the dialects of  the interior plateau, southern Qinghai, eastern Tibet, and parts of western  Sichuan; and Amdo or Northeastern, including the dialects of northern  Qinghai, southern Gansu, and northern Sichuan.

Frequency  decreases from head to foot. Unlike a spasm, a cramp, or the movements  of chorea or epilepsy, it does not interfere with other movement and can  be held off for a time. It can become ingrained as a habit of which the  person (most often a nervous child 5-12 years old) is unaware. Most tics  are probably psychological, but similar movements occur in some physi�  cal disorders (e.g., late-stage encephalitis). People with tics have some  control over the movement but feel impelled to go through with it to feel  better. Tension increases the movement�s likelihood, and distraction  reduces it.

In addition to the  alternating submergence and exposure, the varying influences of fresh  river water and salty marine waters cause physical conditions to vary more  widely than in any other marine environment. The mud of a tidal flat is  usually rich in dissolved nutrients, plankton, and organic debris, and it  supports large numbers of small animals such as crabs and worms.

Tides result from differences in the gravitational  forces exerted at different points on the Earth�s surface by another body  (such as the Moon). Although any celestial body (e.g., Jupiter) produces  minute tidal effects, the majority of the tidal forces on the Earth are raised  by the Sun (because of its enormous mass) and the Moon (because of its  proximity to Earth). In fact, the tidal forces from the Moon are about twice  as strong as those from the Sun. The largest tides (spring tides, exhibit�  ing very large change in sea level between high and low tides) occur at  the new and full moon, when the Earth, the Moon, and the Sun are aligned  and the Sun�s tidal forces are added to those of the Moon. The smallest  tides (neap tides) occur when the Sun and Moon are at right angles (from  Earth), when the tidal forces from the Sun partially cancel those from the  Moon. The geometry of the coastline and of the water�s basin also affects  the range of the tides.</p><p>Tieclc\'tek\, (Johann) Ludwig (b. May 31, 1773, Berlin, Prussia�d.

March 5, 1696, Venice�d. March 27, 1770, Madrid) Italian  painter and etcher. In the 1730s and �40s the Venetian clergy and nobility  vied for his works. In 1750 he went to Wurzburg with his sons and col�  laborators, Giovanni Domenico Tiepolo and Lorenzo Tiepolo, to decorate  the prince-archbishop�s palace. His Wurzburg frescoes and canvases are  his most boldly luminous works. In 1762 he escaped the political dise�  quilibrium of the Seven Years� War by accepting an invitation to paint  ceilings in the royal palace in Madrid, again with his sons, his last great  undertaking; he remained in Spain until his death. Although he initially  used a melancholic chiaroscuro style, his later work is full of bright colour  and bold brushwork. His luminous, poetic frescoes both extend the tra�  dition of Baroque ceiling decoration and epitomize Rococo lightness and  elegance.</p><p>Tiepolo Vtye-po-lo\, Giovanni Domenico or Giandomenico  Tiepolo (b.

He was apprenticed to his father, Giovanni Bat�  tista Tiepolo, in Venice in the early 1740s and worked with him in Madrid  from 1762 until the elder�s death in 1770. His most notable early works  are the chinoiserie decorations of the Villa Valmarana in Vicenza (1757).  Back in Venice, he executed several frescoes and paintings of scenes from  the commedia dell�arte. A talented genre painter and caricaturist, he was  famous for his many engravings and etchings after his own and his  father�s designs.</p><p>Tierra del Fuego \te-,er-9-thel- , fwa-go\ Archipelago at the southern  extremity of South America.

About  two-thirds of the islands are in Chile, and the remainder are in Argentina.  The main island, Tierra del Fuego, is divided roughly equally between  Chile (west) and Argentina (east); the city of Ushuaia, Arg., there is the  southernmost city in the world.

Tigers are solitary, nocturnal hunters, preying on  medium-sized mammals (e.g., deer). Locality and subspecies determine  size, colour, and stripes. Southern tigers, such as the Bengal tiger (P. tigris  tigris), are smaller and more brightly coloured than northern ones, such  as the rare Siberian tiger (P. tigris altaica ). Males grow to more than 3 ft  (1 m) high and 7 ft (2.2 m) long, excluding the 3-ft (1-m) tail, and may  weigh 350-640 lb (160-290 kg). Tigers live about 11 years. The persis�  tent use of tiger parts as tonics or medicines, despite evidence refuting  their efficacy, is rooted in the awe that the cat has inspired for millennia.  Although internationally protected, tigers are seriously endangered; their  populations shrank by more than 90% in the last century, and three sub�  species are now extinct.</p><p>Bengal tiger (Panthera tigris tigris ).</p><p>� SILVESTRIS/AUSTRALASIAN NATURE TRANSPARENCIES</p><p>tiger beetle Any of some 2,000 species (family Cicindelidae) of vora�  cious beetles, found worldwide but  mostly in the tropics and subtropics.</p><p>The larva waits at the top of its bur�  row (up to 2 ft, or 0.7 m, deep) and  grasps approaching insect prey with  sicklelike jaws. Hooks on the abdo�  men anchor it so that the struggling  victim cannot pull away, and the  prey is dragged into the burrow and  eaten. The slender, long-legged  adults, less than an inch (25 mm)  long, have long jaws that can inflict  a painful bite. Many are iridescent  blue, green, orange, or scarlet.</p><p>tiger moth Any of more than 3,500 species (family Arctiidae) of moths,  many with furry or hairy larvae called woolly bears. Most adults have a  thick body and white, orange, or green wings. At rest, the wings are folded  rooflike over the body. The fall webworm (Hyphantria cunea ) is a seri�  ous pest. The caterpillars construct webs over leaves, sometimes cover�  ing large areas with silken sheets. They pupate aboveground in a cocoon  made of larval hairs and silk. The Isabella tiger moth (Isia isabella) attains  a wingspan of 1.5-2 in. (37-50 mm). Black spots mark its abdomen and  yellow wings.</p><p>tiger shark Potentially dangerous shark (Galeocerdo cuvieri, family  Carcharhinidae), found worldwide in warm oceans, from the shoreline to  the open sea.

Its dramatic land�  scape includes plateau regions more than 10,000 ft (3,000 m) high and  plains below sea level. Though vegetation is sparse, the population  engages in agriculture and stock raising. Tigray contains the core of the  ancient Aksum kingdom, as well as Ethiopia�s oldest known town, the  3,000-year-old Yeha. It formerly controlled trade routes from the Red Sea  to the empire in the south. Its status declined when it lost control of the  coast in the 16th century; it was subsequently dominated by the south and  was later threatened by the Egyptian, Sudanese, British, and Italian  armies. A rebellion begun in 1975 against the Ethiopian government  aggravated the effects of a disastrous drought and famine in 1984-85. In  1999 Ethiopia�s border war with Eritrea led to the displacement of more  than 300,000 people in Tigray, and famine is a persistent threat.</p><p>Tigris \'t!-gros\ River Arabic Dijlah \'dij-b\ Turkish Dicle biblical  Hiddekel River, Turkey and Iraq.

Through two weekly newspapers, he voiced his criticisms of British rule  in India, hoping to widen the popularity of the nationalist movement  beyond the upper classes. In response to the Partition of Bengal (1905)  he initiated a boycott of British goods and passive resistance, two forms  of protest later adopted by Mohandas K. Gandhi. He left the Indian  National Congress in 1907 when he was deported for sedition but rejoined  in 1916, in time to sign a Hindu-Muslim accord with Mohammed Ali Jin-  nah.

He was a leader  of New York�s Democratic Party, and, as state party chairman (1865-75),  he effected the overthrow of the Tammany Hall boss William Marcy Tweed.  As governor (1875-76) he continued his reforms, exposing the Canal  Ring, a group of politicians and contractors who had defrauded the state.  In 1876 he was the Democratic nominee for president. The bitterly fought  campaign ended in a popular-vote victory for Tilden, but Republicans  contested the results in four states. To settle the controversy. Congress  appointed the Electoral Commission, which decided in favour of the Repub�  lican candidate Rutherford B. Hayes (see also electoral college).

Tiles traditionally have been made of glazed or unglazed fired clay, but</p><p>modern tiles are also made of plastic, glass, asphalt, and even cork.  Ceramic tiles, used for walls, floors, and countertops, are usually machine-  pressed, made of fine clays, and very hard. Quarry tiles (used for flooring)  and terra-cotta, made of natural clays, are less hard and more porous but  very popular for economic and aesthetic reasons. Structural tile, made of  fired clay, is a hollow tile containing parallel cells or cores and is used for  building partitions. Roof tiles of baked clay and of marble were used in  ancient Greece. Tiles came to be widely used in Islamic architecture. Mul�  ticoloured, glazed tiles were common in Spain from an early period (see  azulejo), and from there spread to Portugal and Latin America. By the 15th  century, tile work was used widely in northern Europe; blue-painted tiles  from Delft, Holland, were especially renowned. Modern clay roofing tiles  may be flat or curved; in the Mediterranean countries, S-shaped tiles (pant�  iles), laid with alternate convex and concave surfaces uppermost, are com�  mon.

He studied at Berlin, Tubingen,  and Halle and was a chaplain with the German army during World War  I. He taught successively at Marburg, Dresden, and Frankfurt am Main.  In 1933 the Nazi takeover prompted him to immigrate to the U.S. With  the aid of Reinhold Niebuhr, he joined the faculty of New York�s Union  Theological Seminary. He became respected for his lucid preaching and  his Systematic Theology, 3 vol. (1951-63). He moved to Harvard Uni�  versity in 1955 and to the University of Chicago in 1962. His theological  system was an unusual combination of biblical, existentialist, and meta�  physical elements, and he attempted to convey an understanding of God  that depended neither on revelation nor on science.

He gained military experience in the  Spanish Army of Flanders fighting under Alessandro Farnese (1585)  against the Dutch and in 1594 joined the emperor Rudolf II�s army against  the Turks. Appointed by Maximilian I of Bavaria to reorganize the Bavar�  ian army (1610), Tilly created an efficient force that became the spear�  head of the Catholic League in the Thirty Years� War. He led the League�s  forces to victories in the Battle of White Mountain (1620) and at Lutter  (1626). In 1630 he added the imperial forces to his command. In 1631  he besieged the Protestant city of Magdeburg, but its destruction proved  disastrous for him.

Factors that determine tilth include the for�  mation and stability of aggregated soil particles, moisture content, degree  of aeration, rate of water infiltration, and drainage. The tilth of a soil can  change rapidly, depending on environmental factors such as changes in  moisture. The objective of tillage (mechanical manipulation of the soil)  is to improve tilth, thereby increasing crop production; in the long term,  however, conventional tillage, especially plowing, often has the opposite  effect, causing the soil to break down and become compacted.</p><p>timber framing Construction of frame or post-and-beam structures  using large, heavy, wood members, specifically lumber 5 in.

Half-timber work, in which the spaces between the heavy visible  frames of interior and exterior walls are filled in with (nonstructural)  material such as brick, plaster, or mud, was common in Asia and Europe.  Half-timbering found its highest expression in the Tudor style.

Timbre largely results from  a characteristic combination of over�  tones produced by different instru�  ments. This distinctive combination  (which usually varies across the  range of pitches) is what principally  permits a listener to distinguish a  clarinet from a flute, an alto from a  tenor, or even a Stradivarius violin  from a Guarneri violin, when both  are sounding the same pitch. One  element of timbre results from the  differing methods of producing the  sounds (blowing, bowing, striking,  etc.), especially audible at the  moment a note begins.</p><p>Timbuktu French Tombouctou</p><p>Town (pop., 1998: 32,000), Mali, on  the southern edge of the Sahara near  the Niger River.

After it was incorpo�  rated within the Mali empire, probably  in the late 13th century, it became a  centre of Islamic culture (c. 1400-  1600). It reached its apex as a com�  mercial and cultural centre under  Songhai rule c. 1500 but declined  rapidly after being conquered by  Moroccan forces in the late 16th  century. The French captured it in  1894. It became part of independent  Mali in 1960. The city was desig�  nated a UNESCO World Heritage site  in 1988.</p><p>time Measured or measurable  period. More broadly, it is a con�  tinuum that lacks spatial dimen�  sions. Philosophers have sought an  understanding of time by focusing  on the broad questions of the relation  between time and the physical world  and the relation between time and consciousness. Those who adopt an  absolutist theory of time regard it as a kind of container within which the</p><p>universe exists and change takes place, and believe that its existence and  properties are independent of the physical universe. According to the rival  relationist theory, time is nothing over and above change in the physical  universe. Largely because of Albert Einstein, it is now held that time can�  not be treated in isolation from space (see space-time). Some argue that  Einstein�s theories of relativity vindicate relationist theories, others that  they vindicate the absolutist theory. The primary issue concerning the  relation between time and consciousness is the extent, if any, to which  time or aspects of time depend on the existence of conscious beings.  Events in time are normally thought of in terms of notions of past, present,  and future, which some philosophers treat as mind-dependent; others  believe that time is independent of perception and hold that past, present,  and future are objective features of the world.

It became the most influential newsmagazine in the  U.S., with a format of short articles arranged in subject �departments,�  which became the standard for later general newsmagazines. After Had�  den�s death in 1929, Luce was long the magazine�s guiding force, and it  reflected his moderately conservative political viewpoint. By the 1970s it  had assumed a more neutral, centrist stance in its reportage.

Such studies were first instituted in offices and facto�  ries in the U.S. in the early 20th century. They were widely adopted as a  means of improving work methods by subdividing the different opera�  tions of a job into measurable elements, and they were in turn used as  aids in standardization of work and in checking the efficiency of workers  and equipment.</p><p>time dilation In the theory of special relativity, the �slowing down� of  a clock as perceived by an observer in relative motion with respect to that  clock.

Located near the Timis River, it was first settled in Neolithic and Roman  times. It was sacked by the Tatars in the 13th century. Its citadel was  rebuilt in the 14th century and for a few years became the residence of  Charles I of Hungary. The Turks held the town from 1552 until the Aus�  trians took it in 1716. Occupied by Serbia in 1919, Timi�oara was allot�  ted to Romania by the 1920 Treaty of Trianon. Antigovemment  demonstrations there in 1989 led to the execution of Pres.

When the city of Syracuse called to its mother city, Corinth,  for help in overthrowing its tyrant, Dionysius the Younger, Timoleon was  chosen to lead the liberation force. By shrewd tactics he defeated the  combined forces of the oppressor and his Carthaginian allies, who he  confined to the western end of the island. He introduced constitutional  safeguards and invited more Greek immigration. He retired in 337.</p><p>Timor Vte-.mor, te-'mor\ Island, southern Malay Archipelago. It is the  easternmost of the Lesser Sunda Islands. Indonesian-Malay peoples live  along the coast and Melanesian aboriginals in the mountains. They speak  dozens of Papuan and Malayan languages, as well as Portuguese in the  east and Indonesian in the west. The Portuguese began trading with Timor  c. 1520. In 1613 the Dutch settled at the island�s southwestern tip, and  the Portuguese moved to the north and east. Treaties in 1860 and 1914  divided the island between them. Netherlands Timor (West Timor) was  occupied by the Japanese in World War II; in 1950 the Dutch transferred  it to Indonesia. East Timor was held by the Portuguese until 1975, when  Indonesian troops invaded and annexed the area; it achieved full sover�  eignty in 2002 (see East Timor).</p><p>timothy Perennial grass (Phleum pratense ) of the family Poaceae (or  Gramineae), native to Europe and widely cultivated as a hay and pasture  grass in North America. The stems grow in large clumps, are 1.5-3 ft  (0.5-1 m) tall, and have swollen, bulblike bases. The flower clusters are  long, dense, and cylindrical. Alpine, or mountain, timothy (P alpinum) is  about half as tall and occurs in wet areas from Greenland to Alaska, and  at high altitudes in many other parts of North America and Europe.</p><p>timpani \'tim-po-ne\ or kettledrums Large bowl-shaped drums with  pedal mechanisms for altering their  pitch by changing the membrane�s  tension. The timpani are the princi�  pal orchestral percussion instru�  ments. Each drum usually has a  range of a fifth; they are classically  used in pairs. Until c. 1800 each  drum was tuned to a single pitch  (usually tonic or dominant) that  could not be altered in performance.</p><p>Primitive kettledrums, or nakers,  were played on horseback by Middle  Eastern cavalry.

Feb. 19, 1405, Otrar, near</p><p>Chimkent) Turkic conqueror of Islamic faith whose conquests reached  from India and Russia to the Mediterranean Sea. Timur took part in cam�  paigns in Transoxania with Chagatai, a descendant of Genghis Khan.  (Timur Lenk, or Tamerlane, means �Timur the Lame,� reflecting the battle  wounds he received.) Through machinations and treachery he took over  Transoxania and proclaimed himself the restorer of the Mongol empire. In  the 1380s he began his conquest of Iran (Persia), taking Khorasan and east�  ern Iran in 1383-85 and western Iran as far as Mesopotamia and Georgia in  1386-94. He occupied Moscow for a year. When revolts broke out in Iran,  he ruthlessly suppressed them, massacring the populations of whole cities.  In 1398 he invaded India, leaving a trail of carnage. Next he marched on  Damascus and Baghdad, deporting the artisans of the former to Samarkand  and destroying all the monuments of the latter. In 1404 he prepared to  march on China but died early in the march. Although Timur strove to make  Samarkand the most splendid city in Asia, he himself preferred to be  always on the move. His most lasting memorials are the architectural  monuments of Samarkand and the dynasty he established, under which  Samarkand became a centre of scholarship and science.</p><p>tin Metallic chemical element, chemical symbol Sn, atomic number 50. It  is a soft, silvery white metal with a bluish tinge, employed since antiquity  in the traditional form of bronze, its alloy with copper. It occurs chiefly  as the dioxide (stannic oxide, Sn0 2 ) in cassiterite. Since it is nontoxic,  ductile, malleable, and easily worked, it is used to plate steel cans (�tin  cans�) for use as food containers and to coat and plate other items. Pure  tin is too weak to be used alone, but its many alloys include soft solder,  pewter, bronze, and low-temperature casting alloys. It has valence 2 or 4  in compounds, including stannous chloride (used in tin galvanizing and  manufacturing polymers and dyes), stannous oxide (used to make tin salts  for chemical reagents and plating), stannous fluoride (used as an anticav�  ity ingredient in toothpastes), stannic chloride (a stabilizer for perfumes  and a source of other tin salts), and stannic oxide (a catalyst and a pol�  ishing powder for steel). Tin bonds with carbon to form organotin com�  pounds, used to stabilize PVC and in biocides and fungicides.</p><p>Tin Pan Alley Genre of U.S. popular music that arose in New York in  the late 19th century. The name was coined by the songwriter Monroe  Rosenfeld as the byname of the street on which the industry was based�  28th Street between Fifth Avenue and Broadway in the early 20th cen�  tury, around Broadway and 32nd Street in the 1920s, and ultimately on  Broadway between 42nd and 50th Streets. �Tin pan� referred to the sound  of pianos furiously pounded by �song pluggers� demonstrating tunes to  publishers. The genre comprised the commercial music of writers of bal�  lads, dance music, and vaudeville songs, and its name eventually became  synonymous with U.S. popular music. Its demise resulted from the rise  of film, audio recording, radio, and TV, which created a demand for more  and different kinds of music, and the growth of commercial songwriting  centres in cities such as Hollywood and Nashville.</p><p>Tinbergen Vtin-.ber-konX, Jan (b.

For 40 years (1933-73) he taught at  The Netherlands School of Economics. As economic adviser to the League  of Nations (1936-38), he studied the economic development of the U.S.  from 1919 to 1932, work that provided a basis for his development of  business cycle theory and methods of economic stabilization. In 1969 he  shared with Ragnar Frisch the first Nobel Prize in Economic Sciences.  Nikolaas Tinbergen was his brother.</p><p>Tinbergen, Nikolaas (b. April 15, 1907, The Hague, Neth.�d.

Brother of Jan Tinbergen, he  received his Ph.D. from the University of Leiden and taught there until  1949, when he took a position at Oxford University. He emphasized the  importance of both instinctive and learned behaviour to survival and used  animal behaviour as a basis for speculation on human violence and aggres�  sion. His observations of seagulls led to important generalizations on  courtship and mating behaviour. From the 1970s he and his wife, Eliza�  beth, studied human behavioral disorders, particularly autism.

Tinguely�s art satirized the mindless over�  production of material goods in advanced industrial society and expressed  his conviction that the essence of both life and art consists of continuous  change, movement, and instability.</p><p>tinplating Applying a coating of tin to thin steel sheet either by dipping  in molten metal or by electrolytic deposition (electroplating); almost all  tinplate is now produced by the latter process, in which the tin coating is  applied without heat. Essentially a sandwich in which the core is strip  steel, tinplate has the strength and formability of steel combined with the  noncorrosive and nontoxic properties of tin, and additionally is easy to  solder. It is used for containers for food and beverages, paints, oils,  tobacco, and numerous other products, as well as in toys, baking equip�  ment, and parts for radio and other electronic equipment. Modern mate�  rials, including stainless steel and plastics, have replaced tinplate in many  common applications.</p><p>Tintoretto orig. Jacopo Robusti (b. c. 1518, Venice, Republic of  Venice�d. May 31, 1594, Venice) Italian painter. His father was a silk  dyer ( tintore ); hence the nickname Tintoretto (�Little Dyer�). His early  influences include Michelangelo and Titian. In Christ and the Adulteress  (c. 1545) figures are set in vast spaces in fanciful perspectives, in dis�  tinctly Mannerist style. In 1548 he became the centre of attention of art�  ists and literary men in Venice with his St. Mark Freeing the Slave, so  rich in structural elements of post-Michelangelo Roman art that it is sur�  prising to learn that he had never visited Rome. By 1555 he was a famous  and sought-after painter, with a style marked by quickness of execution,  great vivacity of colour, a predilection for variegated perspective, and a  dynamic conception of space. In his most important undertaking, the  decoration of Venice�s Scuola Grande di San Rocco (1564-88), he exhib�  ited his passionate style and profound religious faith. His technique and  vision were wholly personal and constantly evolving. Historians of mod�  ern art recognize him as the greatest representative of Mannerism, inter�  preted in accordance with the great tradition of Venice.</p><p>Tipitaka See Tripitaka</p><p>Tippecanoe V.ti-po-ko-'nuV Battle of (Nov. 7, 1811) Victory by U.S.  troops over the Shawnee.

At the Indian capital of Prophetstown on  the Tippecanoe River in Indiana, the Indians attacked the troops but were  repulsed. Both sides suffered equal losses, but the battle was considered  a victory for Harrison and helped establish him as a national figure.</p><p>Tippett Vtip-atV Sir Michael (Kemp) (b. Jan. 2, 1905, London,  Eng.�d. Jan. 8, 1998, London) British composer. Tippett studied compo�  sition (1923-28) at the Royal College of Music. His early music was con�  servative, but in the late 1930s he developed a personal, modernistic idiom  that was marked by rhapsodic lyricism, intricate counterpoint, and poly�  phonic rhythms that have a lilting, bounding quality. He devoted most of  his energies to compositions with words (generally his own), including the  cantatas A Child of Our Time (1941) and The Mask of Time (1984), and the  operas The Midsummer Marriage (1952), King Priam (1961), The Knot  Garden (1969), and The Ice Break (1976). Beginning with King Priam, his  surging rhythms and lush harmonies gave way to a starker, more taut style.  His instrumental works include symphonies and string quartets.</p><p>Tirane or Tirana \ti-'ra-no\ City (pop., 1999 est.: 279,000), capital of  Albania. Founded in the early 17th century by a Turkish general, it gradu�  ally became a trading centre at the junction of roads and caravan trails. It  was named the capital of Albania in 1920. In World War II Tirane was  occupied by Axis forces (1939�44). It is Albania�s largest city and main  industrial and cultural centre, home to the national library and theatre and  site of the University of Tirane (1957).</p><p>tire Rubber cushion that fits around a wheel and usually contains com�  pressed air. Solid-rubber tires were used on road vehicles until they were  replaced by air-filled pneumatic tires, which, although first patented by  Robert Thomson (1822-1873) in 1845, came into common use only when  John Dunlop (1840-1921) put them on bicycles in 1888 and the French  manufacturer Michelin began to produce them for motor vehicles. The</p><p>tire consisted of an inner tube containing compressed air that was cov�  ered by an outer rubber casing to provide traction. In the 1950s tubeless  tires became standard on most automobiles. Improved tire construction  produced the radial-ply tire.</p><p>Tiresias \tl-'re-se-9s\ In Greek mythology, a blind Theban seer. In Hom�  er�s Odyssey he retained his prophetic gifts even in the underworld, where  Odysseus was sent to consult him. His prophecy led to the tragedy of  Oedipus. It was said that Tiresias lived for seven generations and that he  was once turned into a woman for killing the female of two mating snakes;  upon thereafter killing the male, he reverted to male. According to one  legend, he was blinded by Hera for arguing, on the basis of his unique  experience, that women derive greater pleasure from sex than men do; his  gift of prophecy was a compensatory gesture from Zeus.</p><p>Tirol or Tyrol Ua-'rol, , t!-,rol\ State (pop., 2001: 673,504), western Aus�  tria. Covering 4,883 sq mi (12,647 sq km), it consists of North Tirol and  East Tirol, separated by the state of Salzburg and the Italian region of  Trentino-Alto Adige. Tirol is a mountainous area bordered by the Bavar�  ian Alps and the Otztaler Alps. Its capital is Innsbruck. Tirol came under  Roman control in the 1st century bc. In the Middle Ages it was ruled by  various counts and bishops until it passed to the Habsburgs in 1363. It was  the scene of revolts in 1525 during the Reformation, and again in 1809  against French and Bavarian rule. The southern Tirol was transferred to  Italy in 1919. Renowned for its skiing, it attracts many tourists.</p><p>Tirpitz \'tir-p3ts\, Alfred von (b. March 19, 1849, Kiistrin, Prussia�d.  March 6, 1930, Ebenhausen, near Munich, Ger.) German naval com�  mander. The son of a Prussian civil servant, he enlisted in the Prussian  Navy in 1865, attended the Kiel Naval School, and was commissioned in  1869. As commander of a torpedo-boat flotilla, he devised new tactical  principles. Promoted to rear admiral, he commanded a cruiser squadron  in East Asia (1896-97). In 1897 he became secretary of state of the impe�  rial navy department and reorganized the German navy into a formidable  high-seas fleet. Promoted to grand admiral (1911), he favoured unlimited  submarine warfare in World War I, but opposition to his policy led to his  resignation in 1916. In 1917 he cofounded the patriotic Fatherland Party.</p><p>Tirso de Molina Vtir-so-da-mo-'le-noV orig. Gabriel Tellez (b.  March 9?, 1584, Madrid, Spain�d. March 12, 1648, Soria) Spanish play�  wright. As a friar of the Mercedarian Order from 1601, he wrote its offi�  cial history (1637). Inspired by Lope de Vega, he drew upon a wide range  of sources and styles for his dramas. Tirso wrote a vast number of works,  of which only about 80 have survived. His best-known play, the tragedy  The Seducer of Seville (1630), introduced the legendary hero-villain Don  Juan. Noted for portraying the psychological conflicts of his characters,  he also wrote the tragedy The Doubted Damned (1635) and Antona Garcia  (1635), which analyzed mob emotion. Though he also excelled in com�  edy, he was the greatest Spanish tragedian of his time.</p><p>tirtha Vtir-t9\ In Hinduism, a holy river, mountain, or other place made  sacred through association with a deity or saint. Such sites are often the  destination of pilgrims and the venue for large religious festivals. A Hindu  will make such a pilgrimage as an act of devotion, to carry out a vow, to  appease a deity, or to seek prosperity. On reaching a tirtha, the pilgrim  will usually bathe, circle the temple or shrine, make an offering, have his  name recorded by the tirtha priests, and listen to evening music and reli�  gious discourses.</p><p>Tirthankara Uir-'tsq-ks-rsX or Jina \'ji-ns\ In Jainism, a saviour who  has succeeded in crossing over life�s stream of rebirths and has made a  path for others to follow. Each cosmic age produces 24 Tirthankaras; the  first are giants, but, as the age proceeds, they decrease in stature and  appear after shorter intervals of time. Of the 24 Tirthankaras of the present  age, each of whom is represented by a symbolic colour and emblem, only  Parshvanatha and Mahavira are considered actual historical figures. The  Tirthankaras are not worshiped as gods but rather honoured as exemplars.

The Argives destroyed it  c. 468 bc. Ruins of its palace and massive walls date from the 15th�12th  centuries bc. The term cyclopean masonry derives from the huge stones  used in its construction, supposedly by the Cyclops for Proteus.

It has been used to study normal and abnormal cell structure; biochemi�  cal, genetic, and reproductive activity; metabolism, functions, and aging  and healing processes; and reactions to physical, chemical, and biologi�  cal agents (e.g., drugs, viruses). A tiny sample of the tissue is spread on  or in a culture medium of biological (e.g., blood serum or tissue extract),  synthetic, or mixed origin having the appropriate nutrients, temperature,  and pH for the cells being incubated. The results are observed with a  microscope, sometimes after treatment (e.g., staining) to highlight par�  ticular features. Some viruses also grow in tissue cultures. Work with tis�  sue cultures has helped identify infections, enzyme deficiencies, and  chromosomal abnormalities; classify brain tumours; and formulate and  test drugs and vaccines.</p><p>Tisza \'ti-sa\, Istvdn, Count (b.

He  entered the Hungarian parliament in 1886 and joined his father, Tisza  Kalman, as a leader of the Liberal Party. A defender of the Austro-  Hungarian dualist system of government and of Hungary�s landed inter�  ests, he served as prime minister (1903-05, 1913-17). He opposed voting  franchise reform and resigned over the king�s 1917 decree for such  reform. A supporter of the alliance with Germany in World War I, he was  held responsible for his country�s suffering and was assassinated by Mag�  yar leftists.</p><p>Tisza, Kalman (b. Dec. 16, 1830, Geszt, Hung., Austrian Empire�d.  March 23, 1902, Budapest) Hungarian politician and premier (1875-90).  A member of an old landowning family, he took part in the struggle for  Hungarian national autonomy within the Austro-Hungarian system of dual  government. After the Compromise of 1867 he formed a coalition of the  nobility, business interests, and small landowners into the new Liberal  Party (1875) and became prime minister. His social, political, economic,  and legal reforms helped Hungary develop into a modern state. He  resigned over interference from the Austrian emperor but continued as  leader of the Liberal Party, with his son, Istvan Tisza.</p><p>Tisza River or Tisa \'ti-sa\ River River, western Ukraine, eastern  Hungary, and northern Serbia and Montenegro.

There were 12 original Titans: the brothers Coeus,  Crius, Cronus, Hyperion, Iapetus, and Oceanus, and the sisters Mnemo�  syne, Phoebe, Rhea, Tethys, Thea, and Themis. Encouraged by Gaea, the  Titans rebelled against their father. Cronus deposed Uranus by castrating  him, and became king himself. Cronus� son Zeus rebelled against his  father, launching a struggle in which most of the Titans sided with Cro�  nus. Zeus and his siblings finally won after 10 years, and Zeus impris�  oned the Titans in a cavity below Tartarus.</p><p>Titan \'tl-t 3 n\ Largest moon of Saturn. Titan is the only satellite in the  solar system known to have clouds and a dense atmosphere. It makes one  rotation on its axis (about every 16 days) for each revolution around Sat�  urn, thus always keeping the same hemisphere toward the planet. With a  diameter of 3,200 mi (5,150 km), Titan is the second largest moon in the  solar system; only Jupiter�s Ganymede is larger. Its density (about 1.9  times that of water) implies that its interior is a mixture of rocky and icy  materials, the latter likely being mostly water ice mixed with frozen  ammonia and methane. Its atmosphere is about 95% nitrogen. Its surface,  veiled in a thick brownish red haze, was largely a mystery until the arrival  at Saturn in 2004 of the Cassini-Huygens spacecraft, which revealed a  complex topography shaped by rains, winds, flowing liquids, and other  processes similar to those acting on Earth�s surface.</p><p>Titan rocket Any of a series of U.S. liquid-fueled rockets originally  developed as intercontinental ballistic missiles (ICBMs) but also used as  space launch vehicles. Titan I missiles (used 1962-65), designed to deliver  a four-megaton nuclear warhead over 5,000 mi (8,000 km) to targets in  the former Soviet Union, were stored in underground silos but had to be  raised to ground level and fueled for launch. By 1965 they had been  replaced by the much larger Titan II, which could be launched directly  from its silo. With a nine-megaton warhead, Titan II was the principal  weapon in the land-based U.S. nuclear arsenal until the 1980s, when it  was replaced by solid-fueled ICBMs (e.g., Minuteman missiles). NASA  used the Titan II to launch Gemini spacecraft in the 1960s; deactivated  Titan II missiles refurbished as space launchers continued to be used into  the 21st century. The Titan IV, developed in the late 1980s, has larger  engines to lift heavy space cargo such as that carried by the space shuttle.  Coupled with the Centaur upper-stage vehicle, it is the largest and most  powerful expendable launch vehicle in the U.S.</p><p>Titanic British luxury passenger liner that sank on April 15, 1912, en  route to New York from Southampton, England, on its maiden voyage.  Over 1,500 of its 2,200 passengers were lost. The largest and most luxu�  rious ship afloat, it had a double-bottomed hull divided into 16 watertight  compartments. Because four of these could be flooded without endanger�  ing its buoyancy, it was considered unsinkable. Shortly before midnight  on April 14, it collided with an iceberg southeast of Cape Race, New�  foundland; five compartments ruptured and the ship sank. As a result, new  rules were drawn up requiring that the number of places in lifeboats equal  the number of passengers (the Titanic had only 1,178 lifeboat places for  2,224 passengers) and that all ships maintain a 24-hour radio watch for  distress signals (a ship less than 20 mi [32 km] away had not heard the  Titanic �s distress signal because no one had been on duty). The Interna�  tional Ice Patrol was established to monitor icebergs in shipping lanes. In  1985 the wreck was found lying upright in two pieces at a depth of 13,000  ft (4,000 m) and was explored by American and French scientists using  an unmanned submersible (see Robert Ballard).</p><p>I I 11 1</p><p>The Titanic.</p><p>THE BETTMANN ARCHIVE</p><p>titanium \tI-'ta-ne-om\ Metallic chemical element, one of the transition  elements, chemical symbol Ti, atomic number 22.

It was enjoined by eccesiasti-  cal law from the 6th century and enforced in Europe by secular law from  the 8th century. After the Reformation, tithes continued to be imposed for  the benefit of both the Protestant and Roman Catholic churches. Tithes  were eventually repealed in France (1789), Ireland (1871), Italy (1887),  and England (1936). In Germany support for churches is collected through  the personal income tax and distributed according to the individual�s reli�  gious affiliation. Tithing was never part of U.S. law, but members of cer�  tain churches (e.g., the Mormons) are required to tithe, and members of  other churches may tithe voluntarily. Tithing was never accepted by the  Eastern Orthodox churches.</p><p>Titian \'ti-shon\ orig. Tiziano Vecellio (b. 1488/90, Pieve di Cadore,  Republic of Venice�d. Aug. 27, 1576, Venice) Italian painter active in  Venice. As a young man he was taught by the Bellini family and worked  closely with Giorgione. His early works are so similar in style to Gior�  gione�s as to be indistinguishable, but soon after Giorgione�s early death  Titian established himself as the leading painter of the Republic of Ven�  ice. Among his most important religious paintings is the revolutionary and  monumental Assumption (1516-18) for Santa Maria dei Frari, in which  the Virgin ascends to heaven in a blaze of colour accompanied by a semi�  circle of angels. Titian was also interested in mythological themes, and  his many depictions of Venus display his work�s sheer beauty and inher�  ent eroticism. Bacchus and Ariadne (1520-23), with its pagan abandon,  is one of the greatest works of Renaissance art. Titian was sought after  for his psychologically penetrating portraits, which include portrayals of  leading Italian aristocrats, religious figures, and Emperor Charles V. He  reached the height of his powers in The Rape ofEuropa (c. 1559-62), one  of several paintings done for Philip II of Spain. He was recognized as  supremely gifted in his lifetime, and his reputation has never declined.</p><p>Titicaca V.te-te-'ka-kaV Lake South American lake, the world�s highest  lake navigable to large vessels. Located in the Altiplano, a high basin of the  Andes Mountains, and on the border between Peru and Bolivia, it lies at an  elevation of about 12,500 ft (3,810 m). The second largest lake in South  America, it covers some 3,200 sq mi (8,300 sq km) and is 120 mi (190 km)  long by 50 mi (80 km) wide. A narrow strait joins the lake�s two bodies of  water, which have 41 islands, some densely populated. The remains of one  of the oldest known American civilizations have been found in the area.  Temple ruins on Titicaca Island mark the spot where, according to legend,  the founders of the Inca were sent down to earth by the sun.</p><p>Tito \'te-to\, Josip Broz orig. Josip Broz (b. May 7, 1892, Kum-  rovec, near Zagreb, Croatia, Austria-Hungary�d. May 4, 1980, Lju�  bljana, Yugos.) Yugoslav politician, premier (1945-53), and president  (1953-80). Born to a peasant family, he fought in the Austro-Hungarian  army in World War I and was captured by the Russians in 1915. While in  Russia, he took part in the July Days demonstrations (1917) and joined the  Bolsheviks. In 1920 he returned to Croatia, where he became a local leader  of the Communist Party of Yugoslavia. He rose in the party hierarchy,  interrupted by a prison term (1928-34), to become its secretary-general  in 1939. In World War II, Tito (a pseudonym he adopted about 1935)  proved an effective leader of Yugoslav Partisans. As marshal from 1943,  he strengthened communist control of Yugoslavia. As premier and presi�  dent, he developed an independent form of socialist rule in defiance of  the Soviet Union, pursued a policy of nonalignment, built ties with other  nonaligned states, and improved relations with the Western powers.  Within Yugoslavia, he established a system of �symmetrical federalism�  (1974) that created equality among the six republics and Serbia�s autono�  mous provinces (including Kosovo), while maintaining tight control to</p><p>prevent separatist movements. After his death, resentment of Serbian  domination led gradually to a dissolution of the federal system.</p><p>Titograd See Podgorica</p><p>titration Ui-'tra-shonX Process of chemical analysis in which the quan�  tity of some constituent of a dissolved sample is determined by adding  an exactly measured quantity of another dissolved substance with which  it reacts in a definite, known proportion. The solution of known concen�  tration is gradually added to the unknown solution from a burette (a long  measuring tube with a valve at the bottom) until the equivalence point  (end point) is reached. The amount of the unknown substance can then  be calculated. The equivalence point is determined by a detectable change,  for instance, of colour in an indicator substance (e.g., litmus) or in an elec�  trical property. Reactions used in titration include acid-base reactions, pre�  cipitations (see solution), formation of complexes, and oxidation-reduction  reactions.

He commanded a Roman legion in Judaea under his father, Ves�  pasian. After Vespasian became emperor (69), he gave Titus full command  in Judaea, whereupon Titus captured and destroyed Jerusalem (70). He  later took charge of the empire�s general military operations. As emperor  he developed goodwill in Rome for his extravagant spending; his projects  included the completion of the Colosseum. He died suddenly, probably  from natural causes, though there were rumours that he was poisoned by  Domitian.</p><p>Tiv People living along the Benue River in Nigeria.

The site has been occupied continuously since prehistoric  times. Originally an independent member of the Latin League and a rival  of nearby Rome, Tivoli came under Roman influence in the 4th century  bc. It received Roman citizenship in 90 bc and attained prosperity as a  summer resort under the early empire. Many wealthy Romans built vil�  las and erected temples in the vicinity, and the buildings� remains are  among the most impressive to survive from antiquity. They include Hadri�  an's Villa and the poet Horace�s Sabine farm. Tivoli is also the site of the  Villa d�Este (begun ad 1550), with its magnificent gardens and unrivaled  Renaissance fountains.</p><p>Tiwanaku \,te-a-wa-'na-ko\ or Tiwanacu Spanish Tiahuanaco</p><p>Major pre-Columbian Andean civilization known from the ruins of the  same name near the southern shore of Lake Titicaca in Bolivia. The Tiwan�  aku civilization spread throughout large areas of Bolivia and Peru and  parts of Argentina and Chile. The main site�s earliest remains may date  from c. 200 bc-c. ad 200 and its major buildings from c. ad 600 to c.  1000. Surviving artifacts include stelae, decorated pottery, and the famous  Gateway of the Sun (Puerta del Sol), an ornamented doorway carved from  a massive stone slab. Much of the culture�s success derived from its  raised-field farming technique, in which elevated planting surfaces were  separated by canals that retained the sun�s heat during the cold nights and  kept the crops from freezing. Algae that grew in the canals was used for  fertilizer. The Tiwanaku culture vanished by 1200.</p><p>tjurunga or churinga Uyu-'raq-goX In native Australian religion, a  ritual object that is a representation or manifestation of a mythical being.  They are symbols of communication between humans and the Dreaming.  Most tjurunga are used in men�s secret and sacred rituals, though some  small objects figure in women�s rituals and still smaller objects in men�s  love magic. At initiation, a boy is introduced to the rituals and tjurunga  of his local descent group. Later, he receives his own tjurunga, with which  he has a personal bond. At a person�s death, the tjurunga is sometimes  buried with the corpse.</p><p>tlachtli Vtlach-tle\ Ball court or field used for the ritual ball game ollama,  played throughout pre-Columbian Mesoamerica.

It is located in a mountainous  region at the foot of La Malinche volcano. Settled by a Nahua people  around the 14th century, it vied for power in the 15 th-16th century with  the Aztec city of Tenochtitlan (modern Mexico City). Though the inhab�  itants initially opposed HernAn Cortes, they later became his allies and  aided him in his defeat of Azetec leader Montezuma II. It was a refuge for  the Spaniards when they were driven out of Tenochtitlan in 1520. Cortes  established the first Christian church (San Francisco) in the Americas  there in 1521. The sanctuary of Our Lady of Ocotlan and archaeological  ruins are nearby.</p><p>Tlaxcala \tla-'ska-la\ State (pop., 2000: 962,646), central Mexico.

In her second form, she was the destructive goddess of gambling and  uncertainty. In middle age, she was able to absorb human wrongdoing. In  her final manifestation, she was a terrifying hag preying on youths. She  was thought to provoke carnal lust and illicit sexual activity, but she could  also grant absolution and remove corruption from the world by eating  sexual filth.</p><p>Tlingit Vtliq-gotX Northernmost group of Northwest Coast Indian peoples  who inhabit the islands and coast of southern Alaska, U.S. The Tlingit  language is thought to be related to Athabaskan. The basic social unit was  the lineage, based on maternal lines of descent; clans and larger units  (moieties) were also important. Each lineage had its own chief, owned  and exploited lands of economic importance, and functioned as a ceremo�  nial unit. The economy was based on salmon fishing, though sea and land  mammals were also hunted. Wood, often decorated with stylized designs,  was used for houses, totem poles, canoes, dishes, and other objects. The  potlatch marked a cycle of rituals mourning the death of a chief.

To diversify the economy, he encouraged agriculture and  the production of textiles and woolen goods. His plan to build a central  temple to replace 11 local temples turned his people against him; higher  authorities decided in his favour, but the temple project was canceled.</p><p>toad Any member of 26 genera (order Anura) of mainly terrestrial, noc�  turnal, tailless amphibians. Toads have a squat body, short legs, external</p><p>fertilization, and teeth in the upper  jaw. They eat insects or small ani�  mals. The more than 300 species of  true toads ( Bufo ) are found almost  worldwide. They are 1-10 in. (2-25  cm) long and have thick, dry, often  warty skin. Poison secreted by  glands on the back and warts irritates  the eyes and mucous membranes of  predators.

When  Christopher Columbus reached the Americas, he reported natives using  tobacco as it is used today, as well as in religious ceremonies. Believed  to have medicinal properties, tobacco was introduced into Europe and the  rest of the world, becoming the chief commodity that British colonists  exchanged for European manufactured articles. Awareness of the numer�  ous serious health risks posed by tobacco, including various cancers and  a range of respiratory diseases, has led to campaigns against its use, but  the number of tobacco users worldwide continues to rise.

In 1918 he converted to the Baha�i religion and his work became  inspired by Asian art and thought. In the 1930s he achieved notoriety with  his �white writing� paintings, consisting of a web of calligraphic marks  painted in white on a gray or coloured ground (e.g., Broadway, 1936),  which soon displaced his representational work.

Regions  include a swampy coastal plain, a northern savanna, and a central moun�  tain range. The developing economy is based largely on agriculture. Chief  crops are cassava, yams, com, cotton, coffee, and cocoa. It is one of the  world�s leading producers of phosphates; food products, beverages, and  cement are also important. Togo is a republic with one legislative house;  its chief of state is the president, supported by the military, and the head  of government is the prime minister. Until 1884 what is now Togo was  an intermediate zone between the states of Asante and Dahomey, and its  various ethnic groups lived in general isolation from each other.

Located north of Samoa, Tokelau consists of three coral atolls�Fakaofu,  Nukunono, and Atafu�each with numerous low-lying islets. Originally  settled by Samoans, the islands were first visited by Europeans in the 18th  century. In 1863 Peruvian slave raiders abducted many islanders; the  abductions and outbreaks of disease reduced the population to about 200.  The British established a protectorate there in 1889. Under the name  Union Islands they were part of the Gilbert and Ellice Islands colony from  1916 to 1925, after which New Zealand was granted jurisdiction. The  islands became part of New Zealand in 1948. The name Tokelau Islands  was adopted in 1946; this was shortened to Tokelau in 1976. In 1994 the  powers that had been held by the territory�s New Zealand administrator  were transferred to the local government on Tokelau.</p><p>Tokharian languages See Tocharian languages</p><p>tokonoma V.to-ko-'no-moV In a Japanese room, an alcove with a low  platform, used for the display of a flower arrangement and hanging scroll  or other art objects.

Jan. 31, 1543, Oka�  zaki, Japan�d. June 1, 1616, Sumpu) Founder of the Tokugawa shogu-  nate (see Tokugawa period) and ruler of Japan (1603-16). Along with Oda  Nobunaga and Toyotomi Hideyoshi, leyasu was one of the three unifiers of  premodern Japan. He allied himself initially with Nobunaga; that alliance  allowed leyasu to survive the vicissitudes of endemic warfare in Japan at  that time and to slowly build up his territory. By the 1580s he had become  an important daimyo in control of a fertile and populous han (domain).  When Nobunaga died, leyasu offered a vow of fealty to Hideyoshi, who  was extending his control over southwestern Japan; leyasu, meanwhile,  enlarged his vassal force and increased his domain�s productivity. In the  1590s he avoided participating in Hideyoshi�s disastrous expeditions to  Korea, instead consolidating his position at home. When Hideyoshi died,  leyasu had the largest and most reliable army and the most productive  and best-organized domain in Japan; he emerged as victor from the ensu�  ing power struggle. He confiscated his enemies� lands and gave them new  domains away from Japan�s heartland, much of which became Tokugawa  property. He received the title of shogun and two years later passed the  title to his son, thereby establishing it as hereditary among the Tokugawa.</p><p>Tokugawa period (1603-1867) In Japanese history, period of the  military government established by Tokugawa Ieyasu with his assumption  of the title of shogun in 1603. The structures leyasu set in place were  effective for governing Japan for the next 264 years. He established his  capital at Edo (modern Tokyo) and assigned daimyo han (domains) accord�  ing to their friendliness or hostility toward the Tokugawa: hostile daimyo  received domains on the nation�s periphery, while allies and collateral  houses were given domains nearer to Edo. Sankin kotai, a system whereby  daimyo alternated residency between Edo and their domain, also helped  the shogunate keep control of the daimyo. To protect Japan from outside  influences, particularly Christian missionaries, a new policy of national  seclusion forbade Japanese to travel abroad and forbade foreigners to visit  Japan (except for Chinese and Dutch traders, who were allowed to trade</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Tokyo &#x25BA; toll I 1919</p><p>only at the port of Nagasaki). Toyotomi Hideyoshi�s division of society into  four fixed classes was preserved, and the samurai (military) class became  the civil bureaucrats, its members paid with stipends of rice. Increased  travel to Edo and other cities stimulated urban development and urban  culture (see Edo culture; Genroku period); the merchant class flourished.  By the mid-18th century the shogunate began to suffer financially, as  attempts at fiscal reform proved largely unsuccessful. During its last 30  years there were numerous peasant uprisings (see ikki) and evidence of  samurai unrest. The shogunate was overthrown by the domains of Sat-  suma and ChoshO in 1867.

The coun�  try�s largest city, it is located in east-central Honshu at the head of Tokyo  Bay. The site has been inhabited since ancient times, and the small fish�  ing village of Edo existed there for centuries before it became the capital  of the Tokugawa shogunate in 1603 (see Tokugawa period). By the 19th  century it was one of the largest cities in the world, with a population  exceeding 1,000,000. Under the Meiji Restoration, in 1868 it replaced  Kyoto as the imperial capital, and Edo was renamed Tokyo (�Eastern  Capital�). A massive earthquake in the region in 1923 destroyed most of  the city and killed at least 100,000 people, but most of it had been rebuilt  by 1930. Much of it was again devastated by U.S. bombing during World  War II and had to be reconstructed. The Summer Olympic Games were held  there in 1964. Tokyo is the administrative, cultural, financial, commer�  cial, and educational centre of Japan and the focus of an extensive urban  complex that includes Kawasaki and Yokohama. Attractions include the  Imperial Palace, encircled by stone-walled moats and broad gardens, and  numerous temples and shrines. There are some 150 institutions of higher  learning, including the University of Tokyo (1877).</p><p>Tokyo, University of State-financed university in Tokyo, the largest  and most prestigious university in Japan.

The area was opened to white settlement after the 1794 Battle of Fallen  Timbers. Formed by the consolidation of two villages in 1833, it figured  in the so-called Toledo War of 1835-36, a bloodless dispute between  Michigan Territory and Ohio over the location of their common bound�  ary. Industrial development was spurred in the 1830s and �40s by the  arrival of canals and railroads. Glassmaking, now a major industry, was  introduced in the late 1880s. A major commercial, industrial, and trans�  portation centre, it handles considerable foreign commerce, and its port  is one of the world�s largest shippers of bituminous coal.

On the Tagus River, it was the stronghold of the Car-  pentini, a powerful Iberian tribe, when it was conquered by Rome in 193  bc. In the 6th century ad it became the Visigoths� capital in Spain. Under  the Moors (712-1085) it became a centre of Hebrew and Arabic culture,  and it was noted for the manufacture of swords. Taken by Alfonso VI in  1085, it became the capital of New Castile and, in 1230, of the united  kingdom of Castilla y Leon. Toledo was noted for its policy of religious  tolerance toward Jews and Arabs during the 11th�15th centuries. It lost  importance after Philip II moved the capital to Madrid in 1560. The French  occupied Toledo during the Peninsular War (1808-14), and Nationalist  forces besieged it (1936) in the Spanish Civil War. Known for its great  wealth of notable architecture, the entire urban area is a national monu�  ment. It was the home of El Greco.</p><p>Toledo, councils of Eighteen councils of the Visigothic church held  in Toledo, Spain, from c. 400 to 702. Most attending were bishops, with  some members of the lower clergy and the nobility. The decisions often  affected civil and political affairs, and nearly all were convoked by kings.  At the third Council of Toledo in 589, King Recared rejected his Arian  faith and accepted Catholicism, an event that led to the unification of  Visigothic Spain with Catholicism as the state religion.</p><p>Toleration Act (1689) Act of the British Parliament that granted free�  dom of worship to Nonconformists, allowing them their own places of  worship and their own teachers and preachers.

A pro�  fessor of Anglo-Saxon and of English language and literature at Oxford  (1925-59), Tolkien achieved fame for his heroic epic The Lord of the Rings  (1954-56), consisting of The Fellowship of the Ring (film, 2001), The Two  Towers (film, 2002), and The Return of the King. The Hobbit (1937) serves  as an introduction to the series, The Silmarillion (1977) as a �prequel.� Set  in the mythical past, the richly inventive tale chronicles the struggle  between good and evil kingdoms to possess a magic ring that controls the  balance of power in the world. In the 1960s its popularity with young  people made it a sociocultural phenomenon, and starting in 2001 the  release of a series of critically acclaimed films renewed interest in the epic.</p><p>toll Sum levied on users of certain roads, canals, bridges, tunnels, and  other such travel and transportation infrastructure, primarily to pay for  construction and maintenance. Tolls were known in the ancient world and  were widely used in medieval Europe as a means of supporting bridge  construction. Canal building, which became extensive in Europe in the  18th�19th centuries, was financed chiefly by tolls, and many major roads  were built by private companies with the right to collect tolls. In the U.S.  the National Road, built beginning in 1806, was initially financed through  the sale of public land, but maintenance problems led Congress to autho�  rize tolls. Toll roads diminished in the latter part of the 19th century, but  the idea was revived with the Pennsylvania Turnpike in the 1930s, and  after World War II many states built toll expressways. In many countries  tolls are also used to finance long-span bridges, major tunnels, and high�  ways. They have also been blamed for both reducing, and abetting, rush-  hour traffic congestion. Canal tolls are still charged in some parts of the  world, notably on the Suez and Panama canals.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1920 I Tolly &#x25BA; Tombstone</p><p>Tolly, Mikhail Barclay de See Mikhail, Prince Barclay de Tolly</p><p>Tolman, Edward C(hace) (b.

Sept.  9, 1828, Yasnaya Polyana, Tula province, Russian Empire�d. Nov. 20,  1910, Astapovo, Ryazan province) Russian writer, one of the world�s  greatest novelists. The scion of prominent aristocrats, Tolstoy spent much  of his life at his family estate of Yasnaya Polyana. After a somewhat dis�  solute youth, he served in the army and traveled in Europe before return�  ing home and starting a school for peasant children. He was already  known as a brilliant writer for the short stories in Sevastopol Sketches  (1855-56) and the novel The Cossacks (1863) when War and Peace  (1865-69) established him as Russia�s preeminent novelist. Set during the  Napoleonic Wars, the novel examines the lives of a large group of char�  acters, centring on the partly autobiographical figure of the spiritually  questing Pierre. Its structure, with its flawless placement of complex char�  acters in a turbulent historical setting, is regarded as one of the great tech�  nical achievements in the history of the Western novel. His other great  novel, Anna Karenina (1875-77), concerns an aristocratic woman who  deserts her husband for a lover and the search for meaning by another  autobiographical character. Levin. After its publication Tolstoy underwent  a spiritual crisis and turned to a form of Christian anarchism. Advocating  simplicity and nonviolence, he devoted himself to social reform. His later  works include The Death of Ivan Ilich (1886), often considered the great�  est novella in Russian literature, and What Is Art? (1898), which con�  demns fashionable aestheticism and celebrates art�s moral and religious  functions. He lived humbly on his great estate, practicing a radical asceti�  cism and in constant conflict with his wife. In November 1910, unable to  bear his situation any longer, he left his estate incognito.

The term is applied loosely to all  kinds of graves, funerary monuments, and memorials. Prehistoric tomb  burial mounds, or barrows (artificial hills of earth and stones piled over  the remains), were usually built around a hut containing personal effects  for use in the afterlife. Burial mounds were a prominent feature of the  Tumulus period in Japan (3rd-6th century); these often spectacular monu�  ments consisted of earthen keyhole-shaped mounds surrounded by moats.  Burial mounds, sometimes shaped like animals, were characteristic also  of Indian cultures of eastern central North America c. 1000 bc-ad 700.  With more advanced technology, brick and stone tombs appeared, often  of imposing size. In Egypt tombs assumed great importance, especially  in the form of pyramids. In medieval Christian thought, the tomb became  a symbol of a heavenly home; this concept appeared in the Roman cata�  combs, whose walls display scenes of paradise.

Population (2005 est.): 98,600.  Capital: Nukualofa. The people are of Polynesian ancestry. Languages:  Tongan, English (both official). Religions: Christianity (mostly Protestant;  also Roman Catholic, other Christians); also Baha�i. Currency: pa�anga.  Tonga comprises an archipelago of some 170 islands that extends north-  south in two parallel chains for roughly 500 mi (800 km). The eastern  islands are low and formed of coral limestone; those in the west are  mountainous and of volcanic origin, and four of the western islands are  active volcanoes. The country has a developing free-market economy  based mainly on agriculture. Chief products include fish, coconuts, sweet  potatoes, and bananas. Tourism also is important. Tonga is a constitutional  monarchy with one legislative house; the head of state and government  is the king, assisted by the privy council. Tonga was inhabited at least  3,000 years ago by people of the Lapita culture. The Tongans developed a  stratified social system headed by a paramount ruler whose dominion by  the 13th century extended as far as the Hawaiian Islands. The Dutch vis�  ited in the 17th century, but effective European contact dates from 1773,  when Capt. James Cook arrived and named the archipelago the Friendly  Islands. The modern kingdom was established during the reign (1845-93)  of King George Tupou I. It became a British protectorate in 1900. This  was dissolved in 1970 when Tonga, the only ancient kingdom surviving  from the pre-European period in Polynesia, achieved complete indepen�  dence within the Commonwealth. Tonga was at the centre of a financial  scandal in the early 21st century when money in a government trust fund  was lost while under the management of an American investor. This added  to the country�s ongoing financial problems.</p><p>Tonghak See Ch'ondogyo</p><p>Tonghak Uprising (1894) Korean peasant rebellion that sparked the  Sino-Japanese War. Despite being persecuted for it, impoverished peas�  ants turned increasingly to Tonghak (�Eastern Learning�; see  Ch'ondogyo), a syncretic, nationalistic religion that opposed Western cul�  ture and espoused equality of all people. When demonstrations staged by  Tonghak followers calling for social reform met with a negative govern�  ment response, the peasantry united with them in a rebellion that suc�  ceeded in defeating government troops in southern Korea. The  government called on China for aid; Japan sent in troops without being  asked, and China and Japan clashed. The rebels laid down their arms to  defuse tensions; nevertheless, the Sino-Japanese War ensued. The leaders  of the uprising, including Ch'oe Si-hyong, were executed.</p><p>tongue Muscular organ on the floor of the mouth. It is important in  motions of eating, drinking, and swallowing, and its complex movements  shape the sounds of speech. Its top surface consists of thousands of raised  projections (papillae). The receptors of taste (taste buds) are embedded in  the papillae and are sensitive to four basic flavours: sweet, salty, sour, and  bitter. More specific flavours are influenced by the sense of smell. The  tongue�s appearance (e.g., coated or red) can give clues to disease else�  where. Disorders of the tongue include cancer (often caused by smoke�  less tobacco), leukoplakia (white patches), fungal infection, and  congenital disorders. Different animals use the tongue to serve varied func�  tions; for example, frogs have an elongated tongue adapted to capturing  prey, the snake�s tongue collects and transfers odours to a specialized  sensory structure to help locate prey, and cats use their tongues for groom�  ing and cleaning.</p><p>tongues, speaking in or glossolalia Utterances approximating  words and speech that are nonetheless generally unintelligible, usually  produced during states of trance or delirium. The religious interpretation  of the phenomenon is that the speaker is possessed by a supernatural spirit,  is in conversation with divine beings, or is the channel of a divine proc�  lamation.

It was part of China from  the 2nd century bc until the Vietnamese won independence in the 10th  century ad. The French seized the area in 1883, making it a protectorate;  it was joined with other regions controlled by France in 1887 to form  French Indochina.

April 9,  1936, Kiel, Ger.) German sociologist. From 1881 he taught principally at  the University of Kiel. In Gemeinschaft und Gesellschaft (1887; �Com�  munity and Society�), he explored the differences between the organic  conception of society, or Gemeinschaft (�community,� a social union  based on traditional rules and a shared sense of solidarity), and the social-  contract conception of society, or Gesellschaft (�society,� a social union  held together by rational self-interest). In practice, he argued, all societ�  ies show elements of both kinds of organization, because human conduct  is neither wholly instinctive nor wholly reasoned.</p><p>tonsil Small mass of lymphoid tissue in the wall of the pharynx. The term  usually refers to the palatine tonsils on each side of the oropharynx. They  are thought to produce antibodies to help prevent respiratory and diges�  tive tract infection but often become infected themselves (see tonsillitis),  mostly in children. There are also pharyngeal tonsils, better known as  adenoids, and lingual tonsils, at the base of the tongue. The last have more  effective drainage than the others and are rarely infected.</p><p>tonsillitis Inflammatory infection of the tonsils, usually with hemolytic  streptococci (see streptococcus) or viruses. The symptoms are sore throat,  trouble in swallowing, fever, and enlarged lymph nodes on the neck. The  infection, which usually lasts about five days, is treated with bed rest and  antiseptic gargling. Sulfa drugs or other antibiotics are prescribed in  severe bacterial infections to prevent complications. Streptococcal infec�  tion can spread to nearby structures. Complications may include abscess,  nephritis, and rheumatic fever. Tonsils that become chronically inflamed and  enlarged require surgical removal (tonsillectomy).</p><p>Tony Awards Annual awards for distinguished achievement in the U.S.  theatre. Named for the actress-producer Antoinette (Tony) Perry (1888�  1946), the annual awards were established in 1947 by the American The�  atre Wing and are intended to recognize excellence in plays and musicals  staged on Broadway. Awards are given for best play, best musical, best  play revival, and best musical revival, and in categories such as acting,  directing, music, choreography, set design, and costume design.</p><p>tool Device for making material changes on other objects, as by cutting,  shearing, striking, rubbing, grinding, squeezing, measuring, or other pro�  cess. A hand tool is a small manual instrument traditionally operated by  the muscular strength of the user; a machine tool is a power-driven mecha�  nism used to cut, shape, or form materials such as wood and metal.

He served in the U.S. House of Representa�  tives (1845-53) and the Senate (1853-61), but he resigned his Senate seat  to help form the Confederate States of America. Disappointed at not being  chosen its president, he served briefly as secretary of state (1861). He  criticized Jefferson Davis�s extralegal policies during the American Civil  War and after the war fled to England. He returned to Georgia in 1867 to  rebuild his law practice and to help revise the state constitution and restore  white supremacy.</p><p>Toomer, Jean orig. Nathan Eugene Toomer (b. Dec. 26, 1894,  Washington, D.C., U.S.�d. March 30, 1967, Doylestown, Pa.) U.S. poet  and novelist of the Harlem Renaissance. He taught briefly before turning  to writing. Cane (1923), considered his best work, is an experimental  novel that depicts the experience of being black in the U.S.; it had a strong  influence on younger black writers. He also wrote for The Dial and other  small magazines. He visited the Gurdjieff Institute in France in 1926 and  led Gurdjieff groups in Harlem and Chicago. He became a Quaker in  1940. Ambivalent about his mixed racial background and preoccupied  with spiritual matters, he avoided race issues in subsequent works.</p><p>tooth Any of the hard structures in the mouth used for biting and chew�  ing and in speech. Each consists of a crown above the gum and one or  more roots below it, embedded in the jaw. Its inner pulp contains the blood  and nerve supply for the bonelike dentin, covered in the crown by enamel,  the hardest tissue in the body. Twenty primary (baby) teeth come in by  age 2 1/2 and fall out between ages 5 and 13 to be replaced by 32 per�  manent teeth. The incisors, in front, are shaped mostly for biting, the  pointed canines for tearing, and the premolars and molars for grinding  food. The teeth are subject to caries (decay), caused by acid from bacte�  ria in plaque, a yellowish film that builds up on teeth. Misalignment of  teeth between the upper and lower jaws can grind down the teeth and  cause problems in chewing. Elsewhere, it is a cosmetic problem. Both  can be treated with braces.

The U.S. House of Representatives  voted to admit Kansas under the Topeka Constitution, but the Senate  blocked the move. The unresolved situation led to the conflict known as  Bleeding Kansas.</p><p>topiary Art of training living trees and shrubs into artificial, decorative  shapes. Topiary is known to have been practiced in the 1st century ad.  The earliest topiary was probably the simple development of edgings,  cones, columns, and spires to accent a garden scene. This architectural  use gave way to elaborate shapes such as ships, hunters, and hounds. The  fashion reached its height in Britain in the late 17th and early 18th cen�  tury but was displaced by the so-called natural garden.</p><p>topology \t3-'pa-lo-je\ In mathematics, the study of the properties of a  geometric object that remains unchanged by deformations such as bend�  ing, stretching, or squeezing but not breaking.

By tradition their  authorship has been ascribed to Moses, but biblical scholarship has shown  that they were written and compiled at a much later date, probably in the  9th-5th century bc, though drawing on much older traditions. The Scroll  of the Torah (Sefer Torah) is kept in the Synagogue Ark.

Canada�s most populous metropolitan area, it lies  on the northern shore of Lake Ontario. Originally inhabited by Seneca  tribes, its site was occupied by a tiny French fort in the mid-18th century.  It was founded in 1793 as York by American colonists loyal to the Brit�  ish. U.S. troops pillaged it during the War of 1812. In 1834 it received  its city charter and current name. It became the capital of Ontario in 1867.  In 1953-54 it joined neighbouring villages, towns, and townships to form  the Municipality of Metropolitan Toronto. In 1967 those 13 municipali�  ties were reduced to six (Toronto, Etobicoke, North York, Scarborough,  York, and the borough of East York), which amalgamated to form the City  of Toronto in 1998. It is Canada�s financial and commercial centre, the  seat of the Toronto Stock Exchange, and a major international trading  centre, with access to Atlantic shipping via the Saint Lawrence Seaway and  to major U.S. ports via the Great Lakes. It produces more than half of  Canada�s manufactured goods. Extensive immigration (1950s-70s)  brought a variety of foreign cultures that transformed it into one of the  liveliest cities on the continent. It is the site of the CN Tower (the world�s  tallest self-supporting man-made structure), the Hockey Hall of Fame, and  the annual Canadian National Exhibition. Its educational institutions  include the University of Toronto (1827).</p><p>Toronto, University of Public university in Toronto, Ontario,  Canada.

It consists essentially of two small  masses at different elevations that are supported at opposite ends of a  beam. The latter is suspended from a wire that twists because the masses  are affected differently by the force of gravity. When the wire is twisted,  an optical system indicates the angle of deflection, and the torque, or  twisting force, can be calculated. The torque is correlated with the gravi�  tational force at the point of observation. Torsion balance may also refer  to a device used in weighing, a type of equal-arm balance.</p><p>torsion bar Rod or bar that resists twisting (see torque) and has a strong  tendency to return to its original position when twisted.

The term  derives from Latin tortum, meaning �something twisted, wrung, or  crooked.� Assault, defamation, malpractice, negligence, nuisance, product  liability, property damage, and trespass are all (apart from their potentially  criminal and contractual aspects) torts.</p><p>tortoise Any of some 40 species (family Testudinidae) of slow-moving,  terrestrial, herbivorous turtles, found  in the Old and New Worlds but  chiefly in Africa and Madagascar.</p><p>Tortoises have a high, domed shell,  heavy elephantlike hind legs, and  hard-scaled forelegs. The four North  American species (genus Gopherus)  have a brown shell, about 8-14 in.</p><p>(20-35 cm) long, and flattened fore�  limbs adapted for burrowing. The  common, or European, tortoise  {Testudo graeca) has a shell about  7-10 in. (18-25 cm) long. Most spe�  cies of giant tortoises on the Galapa�  gos and other islands are now rare or  extinct. One captive Galapagos tor�  toise had a shell 4.25 ft (1.3 m) long and weighed 300 lbs (140 kg).</p><p>torture Infliction of intolerable physical or psychological pain. Torture  has been used by governments throughout history for punishment, coer�  cion, and intimidation and for extracting confessions and information. A  common practice in ancient times, it was defended by Aristotle but elo�  quently opposed by Cicero, Seneca, and St. Augustine. Beginning in the  12th century, torture was increasingly used in Europe; from the mid-14th  through the 18th century it was a common part of the legal proceedings  of most European countries. The Roman Catholic church supported its  use by the Inquisition in cases of heresy. Common instruments of torture  were the strappado (for repeatedly hoisting the body by the wrists behind  the back and dropping it), the rack (for stretching the limbs and body),  and the thumbscrew (for crushing the thumbs). By 1800 torture was ille�  gal in many European countries, but it became common again in the 20th  century, notably in Nazi Germany and the Soviet Union, and it is still  widely practiced in Latin America, Africa, and the Middle East. In 1984  the United Nations adopted an international convention against torture and  other forms of cruel, inhuman, and degrading treatment. By the early 21st</p><p>century some 130 countries were party to the convention. The belief that  only sadists are capable of committing torture was challenged by a study  in the 1960s that found that ordinary people could be easily persuaded to  inflict pain on others.</p><p>Tory Member of a political group in England, especially in the 18th cen�  tury. Originally an Irish term for an outlaw, the name was applied as a  term of abuse to those who supported the hereditary right of James, the  Catholic duke of York (later James II), to succeed to the throne of England.  They were opposed by the Whigs in that struggle (1679), but the Tories  later modified their doctrine of divine-right absolutism. They came to  represent the resistance, mainly by the country gentry, to religious tolera�  tion and foreign entanglements. The Tories� political power diminished  after Viscount Bolingbroke, a leading Tory, fled to France in 1715; Tory  sentiment subsequently survived in the unsuccessful Jacobite movement.  After 1784, William Pitt the Younger emerged as the leader of a new Tory  party, representing the country gentry, merchants, and administrators.  After 1815, the party gradually evolved into the Conservative Party, whose  members are still referred to as Tories.</p><p>Tosa \'to-sa\ Historic region of the Japanese island of Shikoku. It dates  at least to the Heian period, when Ki no Tsurayuki (8687-9457), editor of  Japan�s first imperially commissioned poetry anthology, wrote a fictional  diary drawing on his experiences as governor of Tosa. In 1571 it became  a unified domain (han) whose daimyo opposed Tokugawa Ieyasu when he  consolidated his control of Japan in the early 17th century; this historical  enmity became important at the time of the Meiji Restoration (1868), when  samurai from Tosa, like those from Satsuma and ChoshO, helped overthrow  the Tokugawa shogunate.

Tosca�  nini entered a conservatory at age nine, studying cello, piano, and com�  position. He began his professional life as a cellist. After substituting for  an indisposed conductor in Giuseppe Verdi�s Aida (Buenos Aires, 1886),  he conducted in various Italian opera houses, giving the premieres of /  Pagliacci (1892) and La Boheme (1896). He was appointed musical direc�  tor of La Scala, Milan, in 1898, and of the Metropolitan Opera, New York  City, in 1908. Principally known for his readings of Verdi�s operas and  Beethoven�s symphonies, he also gave remarkable performances of the  music of Richard Wagner. Toscanini conducted the New York  Philharmonic-Symphony Orchestra from 1928 to 1936. In 1930 he  became the first non-German to conduct at Bayreuth, but he stopped per�  forming in Germany to protest Nazi policies. The NBC Orchestra was  formed for him in 1937, and he conducted it until his retirement in 1954.</p><p>Tosefta \,to-sef-'ta, to-'sef-toV Supplements to the Mishna compiled c. ad  300. The Tosefta consists of laws attributed to the authorities named in  the Mishna and generally follows the topical program and organization  of the Mishna. Both works were the effort of Jewish scholars, working  mostly in Palestine, who gathered, evaluated, and correlated the most  important traditions from a vast and heterogeneous mass of material that  had developed since the time of Ezra (c. 450 bc). The Tosefta may have  been meant to complement the Mishna by preserving material that  appeared marginal or contradictory.</p><p>Tostig \'tas-tig\ (d. Sept. 25, 1066, Stamford Bridge, Yorkshire, Eng.)  Anglo-Saxon earl of Northumbria. He had strong ties with Norway and  became earl of Northumbria in 1055; his severity in subduing the wild  northern district stirred revolt in 1065. The rebels won the support of  Tostig�s brother Earl Harold (later Harold II) at Oxford, and Tostig went  into exile. He gave his services to William I (the Conqueror) and harried  the English coast, then joined Norway�s king Harald III Sigurdsson in his  invasion of England. Tostig was killed when his brother Harold defeated  the invading army at Stamford Bridge.</p><p>total internal reflection Complete reflection of a ray of light in a  medium such as water or glass, from the surrounding surfaces back into  the medium. It occurs when the angle of incidence is greater than a cer�  tain limiting angle, called the critical angle. In general, it takes place at  the boundary between two transparent media when a ray of light in a  medium of higher index of refraction approaches another medium of  lower index of refraction at more than the critical angle. At all angles less  than the critical angle, both reflection and refraction occur. Total internal  reflection is responsible for rainbows, atmospheric halos, the sparkle of a  diamond, and the path of light through optical fibres.</p><p>Galapagos tortoise (Geochelone ele-  phantopus).</p><p>FRANCISCO ERIZE-BRUCE COLEMAN LTD.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1926 I Total Quality Control &#x25BA; Toulouse-Lautrec</p><p>Total Quality Control (TQC) System for optimizing production  based on ideas developed by Japanese industries from the 1950s on. The  system, which blends Western and Eastern ideas, began with the concept  of quality circles, in which groups of 10-20 workers were given respon�  sibility for the quality of the products they produced. It gradually evolved  into various techniques involving both workers and managers to maxi�  mize productivity and quality, including close monitoring of staff and  excellent customer service. The concept of kaizen, the notion that  improvement must involve all members of a company, is central to TQC.  See also production management.</p><p>Total Quality Management (TQM) Management practices  designed to improve the performance of organizational processes in busi�  ness and industry. Based on concepts developed by statistician and man�  agement theorist W.

See also International Organization for  Standardization (ISO); Total Quality Control (TQC).</p><p>total war Military conflict in which the contenders mobilize all of their  civilian and military resources in order to obtain a complete victory. It is  distinguished from the partial commitment of lives and resources in lim�  ited war. The modem concept of total war is traced to Carl von Clause-  witz, who stressed the importance of crushing the adversary�s forces in  battle and described wars as tending constantly to escalate in violence  toward a theoretical absolute. The classic 20th-century work is Erich  Ludendorff�s The Total War (1935). World Wars I and II are usually  regarded as total wars. After World War II, especially during the Cold  War, the prospect of an all-out nuclear war made the major powers reluc�  tant to engage in full-scale international warfare or allow their client states  to do so.</p><p>totalitarianism Form of government that subordinates all aspects of  its citizens� lives to the authority of the state, with a single charismatic  leader as the ultimate authority. The term was coined in the early 1920s  by Benito Mussolini, but totalitarianism has existed throughout history  throughout the world (e.g., Qin dynasty China). It is distinguished from  dictatorship and authoritarianism by its supplanting of all political institu�  tions and all old legal and social traditions with new ones to meet the  state�s needs, which are usually highly focused. Large-scale, organized  violence may be legitimized. The police operate without the constraint of  laws and regulations. Where pursuit of the state�s goal is the only ideo�  logical foundation for such a government, achievement of the goal can  never be acknowledged. Hannah Arendt�s Origins of Totalitarianism  (1951) is the standard work on the subject.</p><p>totem pole Carved and painted vertical log, constructed by many  Northwest Coast Indian peoples. The poles display mythological images,  usually animal spirits, whose significance is their association with the lin�  eage. Each figure represents a type of family crest. Some poles relate a  family legend in the form of pictographs. Poles are erected to identify the  owner of a house or other property, welcome visitors, indicate a portal or  passageway, mark a gravesite, and even to ridicule an important person  who failed in some way. See also symbol; totemism.</p><p>totemism Complex of ideas and practices based on the belief in kin�  ship or mystical relationship between a group (or individual) and a natu�  ral object, such as an animal or plant. The term derives from the Ojibwa  word ototeman, signifying a blood relationship. A society exhibits  totemism if it is divided into an apparently fixed number of clans, each  of which has a specific relationship to an animate or inanimate species  (totem). A totem may be a feared or respected hunted animal or an edible  plant. Very commonly connected with origin myths and with instituted  morality, the totem is almost always hedged about with taboos of avoid�  ance or of strictly ritualized contact. Totem, taboo, and exogamy seem to  be inextricably intertwined. See also totem pole.</p><p>Totonac V.to-to-'nakV North American Indians of east-central Mexico.  Some live on cool, rainy high mesas, others in the hot, humid lowlands.  Both groups are farmers, but the highlanders sometimes engage in ped�  dling and wage labour as well and often work on lowland farms in the  off-season. Most farm their own land and also perform required labour on  land collectively owned by the village. They profess Roman Catholicism  but have adapted it to their traditional beliefs.</p><p>toucan Vtu-,kan\ Any of about 40 species (family Ramphastidae) of  large-billed, long-tailed Central and  South American birds. Many species  are black with a bold breast colour;  their thick, saw-edged bills are  brightly and distinctively coloured.</p><p>Bands of toucans emit loud barks,  bugling calls, and harsh croaks. They  eat fruit, insects, lizards, and nestling  birds. Toucans deposit two to four  eggs in an unlined natural tree cav�  ity or an abandoned woodpecker  hole. Ramphastos species are up to  24 in. (60 cm) long, a third of which  may be the bill. Smaller species (tou-  canets) are 10-14 in. (25-35 cm)  long.</p><p>touch-me-not Either of two  North American impatiens, also  known as jewelweed or snapweed, growing in moist areas. Impatiens  capensis, also called I. biflora, typically has crimson-spotted orange flow�  ers; I. pallida has yellow to white flowers, sometimes spotted with  brownish-red. They are common weeds native to extensive regions of  eastern North America. Their juice is said to be a remedy for poison-ivy  rashes.</p><p>touch reception See mechanoreception</p><p>touchstone Black, silica-containing stone used in assaying to determine  the purity of gold and silver. The metal to be assayed is rubbed on the  touchstone, and then a sample of metal of known purity is rubbed on the  stone right next to it. The streaks of metal on the stone are treated with  nitric acid, which dissolves impurities, thus increasing the contrast  between the two samples when compared. Because other metals, such as  copper, can be alloyed to silver without changing its colour significantly,  the touchstone method is not usually used now to assay silver, though it  is still used to assay gold and provides a reasonably accurate guide to  quality.</p><p>Toulon \tii-'lo n . Siege of (Aug. 28-Dec. 19, 1793) Military engage�  ment in the French Revolutionary Wars. French royalists handed over the  naval base and arsenal at Toulon, France, to an Anglo-Spanish fleet in  August. The French Revolutionary army began a siege to recapture the  port city and, after months of preparations, successfully assaulted the  allied-held forts commanding the anchorage. A battery of French guns,  commanded by the young Napoleon Bonaparte, fired on the British fleet  and forced it to evacuate the inner harbour, though British and Spanish  troops blew up the arsenal and burned 42 French ships before leaving.  For his key role in the victory, Napoleon was promoted to brigadier gen�  eral.</p><p>Toulouse \tii-'luz\ ancient Tolosa City (pop., 2004 est.: 426,700), on  the Garonne River in southern France. Founded in ancient times, it was  taken from its Celtic inhabitants by the Romans in the 1st century bc.  After ad 778 it became the seat of the feudal countship of Toulouse. Prot�  estants were massacred there during the 16th-century Wars of Religion. In  1814 it was the scene of the British victory over the French in the last  battle of the Peninsular War. A rail junction and canal port, Toulouse is a  centre of the French aviation industry. It has many historic buildings,  including a Gothic cathedral and a Romanesque basilica, and the tomb of  St. Thomas Aquinas. The university, founded in 1229, is one of the oldest  in the world.</p><p>Toulouse-Lautrec \tu-Tuz-lo-'trek\ (-Monfa), Henri (-Marie-  Raymond) de (b. Nov. 24, 1864, Albi, France�d. Sept. 9, 1901, Mal-  rome) French painter and graphic artist. Born to an old aristocratic family,  he developed his interest in art during lengthy convalescence after both  his legs were fractured in separate accidents (1878, 1879) that left them  permanently stunted and made walking difficult. In 1881 he resolved to  become an artist; after taking instruction, he established a studio in the  Montmartre district of Paris in 1884 and began his lifelong association  with the area�s cafes, cabarets, entertainers, and artists. He captured the  effect of the movement of dancers, circus performers, and other enter�  tainers by simplifying outlines and juxtaposing intense colours; the result  was an art throbbing with life and energy. His lithographs were among  his most powerful works, and his memorable posters helped define the</p><p>Gray-breasted mountain toucan (Andi-  gena hypoglauca).</p><p>PAINTING BY JOHN P.

His pieces are often sharply satirical, but he was  also capable of great sympathy, seen most poignantly in his studies of  prostitutes (e.g.. At the Salon, 1896). His extraordinary style helped set  the course of avant-garde art for decades to come. A heavy drinker, he  died at 36.</p><p>Toungoo Vtauq-.giA dynasty Ruling house in Myanmar (Burma) from  the 15th or 16th century to the 18th century. The founder of the empire  is considered to be either King Minkyinyo (r. 1486-1531) or his son Tab-  inshwehti (r. 1531-50), who expanded the empire and welded it together.  Tabinshwehti�s brother-in-law Bayinnaung (r. 1551-81) extended the  dynasty�s reach to include much of Laos and Siam (Thailand). No ruler  ever managed to conquer Arakan (in southern Myanmar), though Tabin-  shwehti, Bayinnaung, and others tried. The empire slowly disintegrated  after Bayinnaung�s death, but the dynasty continued until 1752.</p><p>Tour, Georges de La See Georges de La Tour</p><p>Tour de France \,tur-d3-'fra n s\ World�s most prestigious and difficult  bicycle race.

Each stage of the race is timed, and the  rider with the lowest aggregate time for all stages is the winner. Estab�  lished in 1903 by Henri Desgrange (b. 1865�d. 1940), a French cyclist  and journalist, the race has been run every year except during the world  wars.</p><p>Touraine \tli-'ren\ Historical region, northwestern central France. It  encompassed the former province of Touraine; its capital was at Tours. In  Roman times it was inhabited by the Gallic Turones. In the 5th century  ad it was incorporated in the Visigothic kingdom, and it passed to the  Franks in 507. Contested by various powers over the succeeding centu�  ries, it came under French influence in the early 13th century. It began to  decline c. 1700, and the province was abolished in 1789 during the French  Revolution. The region, which includes the Loire River valley, known for  its magnificent chateaus, is sometimes called the Garden of France.</p><p>Toure \tii-'ra\, (Ahmed) Sekou (b.

Toure, who claimed  to be descended from Samory, helped lead Guinea�s campaign for inde�  pendence in 1958. He actively supported Kwame Nkrumah�s program for  African unity and gave Nkrumah asylum when he was deposed in 1966.  A member of the (Organization of African Unity (now African Union), he  was viewed internationally as a moderate Islamic leader. After an unsuc�  cessful invasion from neighbouring Portuguese Guinea (now Guinea-  Bissau) in 1971, he imposed harsh domestic measures and ruled with an  iron hand.</p><p>Tourette \tu-'ret\ syndrome Rare neurological disease that causes  repetitive motor and vocal tics. Named for Georges Gilles de la Tourette,  who first described it in 1885, it occurs worldwide, is usually inherited,  generally begins at ages 2-15, and is three times more common in males.  Motor tics occur first in about 80% of cases, compulsions to utter abnor�  mal sounds in the rest. A compulsion to utter obscenities, once thought  characteristic, is often absent. Repetition of words heard and spontaneous  repetition of one�s own words are two distinctive symptoms. Other vocal  tics may include meaningless sounds. Motor tics may be virtually unno-  ticeable; more complex ones may appear intentional (e.g., hopping, clap�  ping). Sleep, intense concentration, and exertion tend to suppress the tics;  emotional stress worsens them. Unlike psychiatric compulsive disorders,  Tourette syndrome has a neurological origin and may improve with psy�  chogenic drugs. Brain neurotransmitter abnormalities may be involved, but  the underlying cause remains uncertain.</p><p>tourmaline Vtor-mo-lon, 'tor-mo-.lenV Complex silicate mineral that is  often used as a gemstone. Three types of tourmaline, distinguished by the  presence of certain elements, are usually recognized: iron tourmaline  (schorl) is black, magnesium tourmaline (dravite) is brown, and alkali  tourmalines may be pink, green, blue, or colourless. Tourmaline is most  common in granite pegmatites. Gem-quality stones are found especially in  the U.S., Brazil, Russia, and Madagascar.</p><p>Tourneur Vtor-norV Cyril (b. c. 1575�d.

His reputation rests</p><p>largely on The Atheist�s Tragedie (1611), a verse drama rich in macabre  imagery. He may be the author of The Revenger�s Tragedie (1607), but  most recent scholarship attributes it to Thomas Middleton; though earlier  than The Atheist�s Tragedie, it is more mature in its structure and sombre  brilliance. Tourneur also wrote the poetical satire The Transformed Meta�  morphosis (1600).</p><p>Tours \'tlir\ City (pop., 1999: 132,820), northwest-central France. Gal�  lic tribes inhabited the site before the Roman conquest. In the 3rd cen�  tury ad it was made an episcopal see, but the Christian community  remained small until St. Martin became bishop in the 4th century; a mag�  nificent basilica was raised above his tomb in the late 5th century, attract�  ing pilgrims for hundreds of years. In the 5th century Tours became part  of the Frankish dominion; Charles Martel defeated Moorish invaders  nearby at the Battle of Tours/Poitiers in 732. Under Alcuin it developed  as a centre of learning. Though it prospered in the Middle Ages, it declined  with the 17th-century emigration of the Protestant Huguenots. It was the  seat of French government during the siege of Paris (1870) in the Franco-  Prussian War. The chief tourist hub for the Loire valley, Tours still has the  remains of the basilica of St. Martin. Tours is the birthplace of Honore  de Balzac.</p><p>Tours/Poitiers \pwa-'tya\, Battle of (October 732) Victory won by  the Frankish mayor of the palace Charles Martel over Muslim invaders  from Spain. Charles led Frankish troops against a Muslim army seeking  to gain control of Aquitaine. The Arab leader, 'Abd-al-Rahman al-Ghafiqi,  was killed, and the Arabs retreated. The battle itself was part of Charles�s  campaign against the Muslims in the south and was not decisive. It did,  however, mark the end of the Muslim invasions of Frankish territory and  contributed to Frankish consolidation of the region. The Frankish victory  greatly enhanced Charles�s prestige and that of his family, the Carolin-  GIANS.</p><p>Toussaint-Louverture Vtii- 1 sa n -Tu-v3r- 1 tur\ orig. Francois Domi�  nique Toussaint (b. c. 1743, Breda, near Cape Francis, Saint-  Domingue�d. April 7, 1803, Fort-de-Joux, Fr.) Leader of the Haitian  independence movement during the French Revolution. Born a slave, he  was freed in 1777. In 1791 he joined a slave rebellion and soon assembled  an army of his own, which he trained in guerrilla warfare. When France  and Spain went to war in 1793, he and other black commanders joined  the Spaniards, but in 1794 he switched his allegiance to the French  because France, unlike Spain, had recently abolished slavery. His revolt  created the first independent nation in Latin America. He rose from lieu�  tenant governor to governor-general of Saint-Domingue and gradually rid  himself of nominal French superiors. Treaties with the British secured  their withdrawal, and he began trade with them and the U.S. In 1801 he  turned his attention to Santo Domingo, the Spanish-controlled portion of  Hispaniola, driving out the Spanish and freeing the slaves there. He made  himself governor-general for life. He was deposed by the French in 1802  and died in custody in France.

It lies in  Towada-Hachimantai National Park, a popular recreation area.</p><p>tower Any freestanding or attached structure that is relatively tall in  proportion to its base. The Romans, Byzantines, and medieval Europeans  built defensive towers as part of the fortifications of their city walls (e.g.,  the Tower of London). Indian temple architecture uses towers of various  types (e.g., the sikhara ). Towers were an important feature of churches  and cathedrals built in the Romanesque and Gothic periods. Some Gothic  church towers were designed to carry a spire; others had flat roofs. The  Italian campanile could either be attached to a church or freestanding. The  use of towers declined somewhat during the Renaissance but reappeared  in Baroque architecture. The use of steel frames enabled buildings to reach  unprecedented heights; the Eiffel Tower in Paris was the first structure to  reveal the true vertical potential of steel construction.</p><p>Tower, Joan (b.

The central keep, or donjon, known as the White Tower because  of its limestone, was begun c. 1078 by William I the Conqueror inside the  Roman city wall. In the 12th�13th century the fortifications were extended  beyond the wall, the White Tower becoming the nucleus of a series of  concentric defenses. The only entrance from the land is at the southwest�  ern corner; when the river was still a major highway, the 13th-century  water gate was much used. Its nickname, Traitors� Gate, derives from the  prisoners brought through it to the Tower, long used as a state prison;  many were murdered or executed there.</p><p>towhee Vto-.he, 'to-,e,\ Any of several North American songbirds (pas�  serine family Fringillidae, sometimes  Emberizidae), long-tailed thicket-  dwellers that noisily scratch the  ground for food.

Town  meetings first took place in New England in the colonial era and are still  largely a New England phenomenon, partly because the region�s towns  tend to hold powers that are granted to counties elsewhere. The meetings  are normally held annually. Executive authority is usually held by a three-  or five-member board. Open town meetings, which are widely regarded  as an exceptionally pure form of democracy, allow all registered voters  to vote on articles listed on the agenda, or warrant; representative town  meetings allow only elected members to vote.</p><p>Townes, Charles H(ard) (b.

In the early 1950s he  and his students constructed the first maser and showed that a similar  device producing visible light was also possible. For his role in the inven�  tion of the maser and later the laser, he shared a 1964 Nobel Prize with  Aleksandr M. Prokhorov (b. 1916) and Nikolay G.

The brothers Job (1699-1765) and Christopher (1701-1773)  were the first generation involved in furniture making. Job�s daughter  married his apprentice John Goddard (see Goddard family). Five of Job�s  sons and two of Christopher�s sons became cabinetmakers. The Goddard-  Townsend group was best known for case furniture characterized by block  fronts (divided into three panels, with the central panel recessed) and  decorative carved shell motifs, frequently in the graceful and somewhat  ornate style developed by Thomas Chippendale.</p><p>Townshend Vtaun-zond\ (of Rainham), Charles Townshend,  2nd Viscount (b. April 18, 1675, Raynham Hall, Norfolk, Eng.�d.  June 21, 1738, Raynham) British politician. He succeeded to his father�s  title in 1687, married the sister of Robert Walpole, and served as secre�  tary of state (1714-16). With Walpole, Townshend led the Whig Party  and became president of the privy council (1720). Again secretary of state  (1721-30), he formed the League of Hanover (1725), which allied Brit�  ain, France, and Prussia against Austria and Spain. He resigned when  Walpole, by then the dominant minister, opposed an aggressive policy  against Austria. Also interested in agricultural reform, Townshend devel�  oped the use of turnips in crop rotation, earning the nickname Turnip  Townshend.</p><p>Townshend Acts (1767) British parliamentary measures to tax the  American colonists. The series of four acts imposed duties on imports of  lead, paint, glass, paper, and tea and established a board of customs com�  missioners to enforce collection. Colonial quartering of British troops was  also revived. The colonists protested the new measures as taxation with�  out representation and resisted compliance. Nonimportation agreements  among colonial merchants cut British imports in half by 1769. In 1770  all the duties except the tax on tea were repealed.</p><p>toxic shock syndrome Bacterial disease caused by a toxin produced  by the bacterium Staphylococcus aureus. It was first recognized in 1978  in women using superabsorbent tampons. High fever, diarrhea, vomiting,  and rash may progress to abdominal tenderness, drop in blood pressure,  shock, respiratory distress, and kidney failure. The syndrome also has other  causes, including postsurgical infection. Antibiotics are not effective. With  intensive supportive therapy, most patients recover in 7-10 days, but  10-15% die. Many patients have a milder recurrence within eight months.</p><p>toxicology Study of poisons and their effects, particularly on living  systems. It overlaps with biochemistry, histology, pharmacology, pathology,  and other fields. Its functions have expanded from identifying poisons and  searching for treatments to include forensic toxicology (see forensic medi�  cine) and testing and detection of a fast-growing number of new poten�  tially toxic substances used in workplaces, in agriculture (e.g., insecticides,  other pesticides, fertilizers), in cosmetics, as food additives, and as drugs  (see drug poisoning). Perhaps the area of largest expansion is the study of  toxic waste in the air, water, and soil, including chlorofluorocarbons, acid  rain, dioxin, and radioactive isotopes.</p><p>toxin Any substance poisonous to an organism; often restricted to poi�  sons produced by living organisms. In addition to those from such micro�  organisms as bacteria (see bacterial diseases), dinoflagellates, and algae,  there are toxins in fungi (mycotoxins; see aflatoxin; mushroom poisoning),  higher plants (phytotoxins), and animals (zootoxins, or venoms). The  plants include nightshade (see nightshade family), poison hemlock, foxglove,  mistletoe, and poison ivy. Many plant toxins (e.g., pyrethrins, nicotine,  rotenone) apparently protect their producers against certain animals (espe�  cially insects) or fungi. Similar defensive secretions in animals may be  widely distributed or concentrated in certain tissues, often with some sort  of delivery system (e.g., spines, fangs). Animals such as spiders and  snakes use venoms to catch prey and often for defense. Many normally  edible fishes and shellfishes become poisonous after feeding on toxic  plants or algae. See also antidote; food poisoning.</p><p>toxoid \'tak-,s6id\ Bacterial toxin that has been made inactive but can  still combine with or stimulate formation of antibodies. In many bacterial  diseases, the bacteria produce a toxin that causes the disease manifesta�  tions. Heating the toxin or treating it chemically converts it into a harm�  less toxoid that can be injected into a human or a nonhuman animal to  confer immunity from subsequent infection. The vaccines for tetanus and  diphtheria are toxoids.</p><p>toy Plaything for a child or infant. Toys survive from the remote past and  from a great variety of cultures. They range from the simple to the com�  plex, from a stick or piece of string that becomes a toy in a child�s hands  to complex mechanical and electronic devices. Perennial favorites include  balls, jump ropes, dolls, drums, whistles, dice, jackstones, board games,  marbles, play weapons, and costumes. In the modern era the toy industry  has grown tremendously, especially with the advent of computer games.</p><p>toy dog Any of several breeds of dogs that were bred to be small, por�  table, good-natured companions. Toy dogs were traditionally pampered  and treasured by aristocracy around the world, and several breeds are  ancient. They range from hairless (e.g., the Chinese crested dog) to pro�  fusely coated (e.g., the Shih tzu). Some breeds, such as the Pekingese, could  be owned only by royalty. The Cavalier King Charles spaniel was a favour�  ite of English royalty. English toy spaniels and toy poodles are popular in  the U.S. The miniature pinscher resembles the Doberman pinscher but has  a different ancestry. Other toy dogs include the affenpinscher, Maltese, pap-  illon, Pomeranian, and Yorkshire terrier.</p><p>Toynbee, Arnold (Joseph) (b. April 14, 1889, London, Eng.�d.

His other works include Civi�  lization on Trial (1948), East to West (1958), and Hellenism (1959).</p><p>Toyota Motor Corp. Largest Japanese automobile manufacturer and  one of the largest automotive companies in the world. It was established  in 1933 as a division of the Toyoda Automatic Loom Works, Ltd., and in  1937 it was incorporated as the Toyota Motor Co., Ltd. Toyota later estab�  lished many related companies, including Toyoda Machine Works, Ltd.  (1941), and Toyota Auto Body, Ltd. (1945). In the 1960s and �70s the  company expanded rapidly, exporting large numbers of cars to foreign  markets. Following consolidations among many of its business units, the  company took the name Toyota Motor Corp. in 1982. It has assembly  plants and distributors in many foreign countries, and it owns subsidiar�  ies that produce cars and car parts, trucks, steel, synthetic resins, and  industrial equipment. Its brands include Toyota and Lexus.</p><p>Toyotomi Hideyoshi \,he-de-'yo-she\ (b. 1536/37, Nakamura, Owari  province, Japan�d. Sept. 18, 1598, Fushimi) One of the three unifiers of  premodern Japan (with Oda Nobunaga and Tokugawa Ieyasu) who brought  the nation out of its Warring States period. He began life as a peasant but  was raised to the rank of samurai (warrior) while a soldier for Nobunaga.  After Nobunaga�s death, he was appointed kampaku (chancellor to the  emperor). Having concluded an alliance with his former rival Ieyasu, he  became in 1590 the head of an alliance of daimyo that constituted a gov�  ernment of national unification. To stabilize society, he imposed the divi�  sion of society into warriors, farmers, artisans, and tradesmen (an  adaptation of ancient Chinese social divisions) and confiscated swords  from all but the warriors. With visions of empire, he made two destruc�  tive but unsuccessful attempts to invade Korea (1592, 1597). After his  death, power passed to Ieyasu.</p><p>TQC See Total Quality Control  TQM See Total Quality Management</p><p>tracery In architecture, bars or ribs used decoratively in windows, espe�  cially the ornamental openwork in Gothic windows. In the earliest phase,  two or three narrow, arched windows were placed close together under a  single large arch, with the section of wall between the small and large  arches pierced by a circular or four-lobed opening. The complexity of this  plate tracery increased, reaching a climax in the magnificent windows of  Chartres Cathedral. After c. 1220 windows began to be subdivided by  mullions, or upright bars, that continued at the head of the window to  branch and form the patterns of bar tracery. Elaborate bar tracery soon  became one of the most important elements of Gothic architecture and one  of its finest achievements, as in the rose windows of the French Rayon-  nant style. The bar tracery of the parallel English Decorated style formed  netlike patterns based on the circle, arch, trefoil, and quatrefoil. By the  late 14th century, the Perpendicular style replaced curvilinear tracery with  straight mullions extending to the top of the main arch, connected at  intervals by horizontal bars.</p><p>trachea \'tra-ke-9\ or windpipe Tube in the throat and upper thoracic  cavity through which air passes in respiration. It begins at the larynx and  splits just above heart level into the two main bronchi, which enter the  lungs. In adults it is about 6 in. (15 cm) long and 1 in. (2.5 cm) in diam�  eter. Its structure�a membrane strengthened by 16-20 cartilage rings  open in the back, with their free ends connected by muscle bands�allows  the trachea to stretch and contract in breathing. An inner mucous mem�  brane has cilia (see cilium) that project inward to trap particles. Muscle  fibres over and alongside the trachea contract in response to cold air or  irritants in inhaled air; in coughing, the airway narrows to about one-sixth  of its normal size to increase the speed and force of exhalation and to  dislodge foreign bodies. Such diseases as diphtheria, syphilis, tuberculosis,  and typhoid often involve the trachea.</p><p>tracheitis \,tra-ke-'I-t3s\ Inflammation and infection of the trachea.  Inhaled irritants can injure the tracheal lining and increase the chance of  infection (bacterial or viral). Acute infections, usually bacterial, produce  fever, fatigue, and swelling of the tracheal lining but generally do no great  damage. Chronic infections, promoted by irritants such as heavy smoking  and alcohol abuse, cause progressive tissue degeneration and scarring.</p><p>tracheophyte See vascular plant</p><p>trachyandesite See latite</p><p>trachyte \'tra-,klt, 'tra-,k!t\ Light-coloured, very fine-grained igneous  rock composed chiefly of alkali feldspar with only minor mafic minerals  (biotite, hornblende, or pyroxene). Trachyte is commonly found in volcanic  regions; like many volcanic rocks, it shows a streaked or banded struc�  ture due to flowing of the congealing lava.</p><p>track and field or athletics Variety of sport competitions held on a  running track and on the adjacent field. It is the oldest form of organized  sports, having been a part of the ancient Olympic Games from c. 776 bc to  ad 393. Modem events include various sprint and middle- and long�  distance races, relay races, hurdling, steeplechase, high jump, pole vault, long</p><p>JUMP, TRIPLE jump, SHOT put, DISCUS throw, HAMMER THROW, JAVELIN throw, DECATH�  LON, PENTATHLON, and HEPTATHLON. CROSS-COUNTRY RUNNING, MARATHONS, and  speed walking, which are rarely held on a track, are usually considered  adjuncts of track-and-field athletics. Events are held indoors and outdoors,  and records are kept separately; some events are modified or eliminated  for indoor competition.</p><p>Tractarian movement See Oxford movement</p><p>tractor High-power, low-speed traction vehicle. The two main types are  wheeled and continuous-track. Most modem tractors are powered by  internal-combustion engines running on gasoline or diesel fuel. Tractors  are used in agriculture, construction, and road building, for pulling equip�  ment such as plows and cultivators, for pushing implements such as bull�  dozers and diggers, and for operating stationary devices such as saws and  winches. The first tractors grew out of the steam engines used on farms in  the late 19th century; in 1892 an Iowa blacksmith, John Froehlich, built  the first farm vehicle powered by a gasoline engine. The tractor revolu�  tionized farming, displacing draft animals and many farm workers. By  World War I the tractor inspired the tanks built by the British and French.</p><p>Tracy, Benjamin F(ranklin) (b. April 26, 1830, near Owego, N.Y.,  U.S.�d. Aug. 6, 1915, New York, N.Y.) U.S. public official. He served  as a county district attorney (1853-59) and, after fighting in the Ameri�  can Civil War, as U.S. attorney (1866-73). Appointed secretary of the  navy (1889-93) by Pres. Benjamin Harrison, he continued the expansion  of the navy begun by William C. Whitney, authorizing construction of new  battleships and cruisers. His departmental reforms and modernization con�  tributed to eventual U.S. naval superiority.</p><p>Tracy, Spencer (Bonaventure) (b. April 5, 1900, Milwaukee, Wis.,  U.S.�d. June 10, 1967, Beverly Hills, Calif.) U.S. film actor. He enrolled  in the American Academy of Dramatic Arts in New York City in 1922  and was soon earning roles on Broadway. He first starred on Broadway  in The Last Mile (1930) and on film in Up the River (1930). Noted for  his craggy features and his sincere performances, he became one of the  top stars of the 1930s and �40s, winning Academy Awards in Captains  Courageous (1937) and Boys Town (1938)�the first actor to win con�  secutive Oscars for best actor�and being nominated for seven other roles,  including Inherit the Wind (1960) and Judgment at Nuremberg (1961).  He had a long relationship with Katharine Hepburn, with whom he cos�  tarred in nine films, including Woman of the Year (1942), Adam�s Rib  (1949), and Guess Who�s Coming to Dinner (1967).</p><p>trade, balance of See balance of trade</p><p>Trade, Board of Organized market for the exchange of commodity  contracts (see commodity exchange). The Toronto Board of Trade, one of  the earliest, was incorporated in 1845. The first grain-futures exchange in  the U.S. was organized in Chicago in 1848. The Chicago Board of Trade  (CBOT) began as a voluntary association of prominent Chicago grain  merchants and was chartered by the Illinois legislature in 1859. Initially  it sold grain by sample; later it introduced a system of inspection and  grading to standardize the market and facilitate trading. By 1858 access  to the trading floor was limited to members with seats on the exchange.  It became the world�s largest commodity exchange in terms of volume  and value of business.</p><p>Trade, Board of in full Lords Commissioners of Trade and  Plantations Advisory body that supervised American colonial affairs.  Established in 1696 to replace the Lords of Trade (1675-96), it examined  colonial legislation to ensure maximum benefit to British trade policies.  The board nominated colonial governors, recommended laws affecting the  colonies to Parliament, and heard complaints from the colonies about its  administrators. It lacked executive or legislative powers, but it became  the primary colonial policy-making body of the British government. It  was abolished in 1782.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1930 I trade &#x25BA; Trajan</p><p>trade, restraint of See restraint of trade</p><p>trade, terms of Relationship between the prices at which a country  sells its exports and the prices paid for its imports. If a country�s export  prices rise relative to import prices, its terms of trade are said to have  moved in a favourable direction, since, in effect, it now receives more  imports for each unit of goods exported. The terms of trade, which depend  on the world supply of and demand for the goods involved, indicate how  the gains from international trade will be distributed among trading coun�  tries. An abrupt change in a country�s terms of trade (e.g., a drastic fall  in the price of its main export) can cause serious problems in its balance  OF PAYMENTS. See also COMPARATIVE ADVANTAGE.</p><p>trade agreement Any contractual arrangement between states con�  cerning their trade relations. Trade agreements may be bilateral or mul�  tilateral, that is, between two states or more than two. For most countries  international trade is regulated by unilateral barriers, including tariffs,  nontariff barriers, and government prohibitions. Trade agreements aim to  reduce such barriers and thus provide all parties with the benefits of  increased trade. Reciprocity is a necessary feature of trade agreements,  since neither state will be willing to sign the agreement unless it expects  to gain as much as it loses. Another common feature is a most-favoured�  nation clause, which provides against the possibility that one of the par�  ties to the current agreement will later offer lower tariffs to another  country. Agreements often include clauses providing for �national treat�  ment of nontariff restrictions,� meaning that both states promise not to  duplicate the properties of tariffs with nontariff restrictions such as dis�  criminatory regulations, selective excise taxes, quotas, and special licens�  ing requirements. General multilateral agreements are sometimes easier  to reach than separate bilateral agreements, since the gains to efficient  producers from worldwide tariff reductions are large enough to warrant  substantial concessions. The most important modem multilateral trade  agreement was the General Agreement on Tariffs and Trade (GATT), which  reduced world tariff levels and greatly expanded world trade. Such agree�  ments continue under the aegis of the World Trade Organization (WTO),  which replaced GATT in 1995. See also NAFTA.</p><p>trade show or trade fair Temporary market organized to promote  trade, where buyers and sellers gather to transact business. Trade fairs are  organized at regular intervals, generally at the same location and time of  year. They are especially common in Europe and Asia, where nearly every  country has at least one major annual international exposition. They range  in scope from those dealing with one industry or branch of industrial pro�  duction to general exhibits of goods and merchandise. Trade shows and  conventions confined to a single industry or even to a specialized seg�  ment of an industry have become increasingly common.</p><p>trademark Mark used by a manufacturer or merchant to identify the  origin or ownership of goods and to distinguish them from others. Trade�  marks may be words or groups of words, letters, numerals, devices,  names, the shape or other presentation of products or their packages, or  combinations of colours. A trademark (indicated by � or, when regis�  tered, by the symbol �) is considered the property of the holder and is  protected by law from unauthorized use by others. In most countries, reg�  istration is a prerequisite for ownership and protection of the mark. In the  U.S., however, the trademark right is granted by the mere use of the mark,  though registration often proves legally advantageous. See also copyright.</p><p>Trades Union Congress (TUC) National organization of British  labour unions. It was founded in 1868 to hold annual conferences of inde�  pendent unions. It included only skilled workers until 1889, when unions  of unskilled workers were admitted. In 1900 the TUC helped found a  separate labour organization, the Labour Representation Committee,  renamed the Labour Party in 1906. After World War I the TUC was gov�  erned by a General Council, which had powers to deal with interunion  conflicts and intervene in disputes with employers. In the 1930s and �40s,  it was the spokesman for industrial labour in dealings with the govern�  ment. The organization continued to help formulate economic policy until  1979, when a Conservative government came to power, leading to a  decline in TUC membership in the 1980s. In the late 1990s, under Labour  prime minister Tony Bair, the TUC was encouraged to back �workplace  partnerships� between unions and employers.</p><p>Trafalgar \tro-'fal-g3r\, Battle of (Oct. 21, 1805) Naval engagement  in the Napoleonic Wars that established British naval supremacy in  Europe.

As Villeneuve tried to slip  out of the besieged port of Cadiz, he was caught by Nelson. The French  ships formed a single line and were attacked by the English at two points.  After sending the famous signal �England expects that every man will do  his duty,� Nelson broke through the centre of the French line and in the  pell-mell battle captured Villeneuve and 20 ships. Near the end of the  battle. Nelson was mortally wounded by a sniper. No British ships were  lost, and Napoleon abandoned his plan to invade England.</p><p>tragedy Drama of a serious and dignified character that typically  describes the development of a conflict between the protagonist and a  superior force (such as destiny, circumstance, or society) and reaches a  sorrowful or disastrous conclusion. Tragedy of a high order has been cre�  ated in three periods and locales, each with a characteristic emphasis and  style: Attica, in Greece, in the 5th century bc; Elizabethan and Jacobean  England (1558-1625); and 17th-century France. The idea of tragedy also  found embodiment in other literary forms, especially the novel. See also  COMEDY.</p><p>tragicomedy Literary genre consisting of dramas that combine ele�  ments of tragedy and comedy. Pautus coined the Latin word tragicoco-  moedia to denote a play in which gods and mortals, masters and slaves  reverse the roles traditionally assigned to them. In the Renaissance and  after, tragicomedy was mainly comic, though Elizabethan and Jacobean  tragedies almost always include some comic or grotesque elements. Mod�  em tragicomedy is sometimes used synonymously with absurdist drama,  which suggests that laughter is the only response left to people faced with  an empty and meaningless existence.</p><p>Traherne Vtro-'harnV Thomas (b. 1637, Hereford, Eng.�d. 1674,  Teddington) English mystical poet and religious writer. He was ordained  in the Anglican church in 1660. Most of his works were unknown for  centuries. The discovery in 1896 in a London street bookstall of the manu�  scripts of Poetical Works (1903) and the prose Centuries of Meditations  (1908) created a literary sensation. Later the manuscript of Poems of  Felicity (1910) was discovered in the British Museum. His poetry, though  sometimes original and intense, is overshadowed by his vivid prose.</p><p>Trail of Tears Forced migration of the Cherokee Indians in 1838-39. In  1835, when gold was discovered on Cherokee land in Georgia, a small  minority of Cherokee ceded all tribal land east of the Mississippi for $5  million. The U.S. Supreme Court invalidated the deal, but the ruling was  ignored by state officials and Pres. Andrew Jackson refused to enforce it.  The subsequent eviction and 116-day forced march of thousands of Chero�  kee to Oklahoma was badly mismanaged, and inadequate food supply,  frigid weather, and the cruelty of escorting troops led to the death of about  4,000 Cherokee.</p><p>trailing arbutus \ar-'byu-t3s\ or mayflower Trailing evergreen  plant ( Epigaea repens) of the heath family, native to sandy or boggy, acidic  woodlands of eastern North America.

Major tranquilizers (antipsychotic agents,  or neuroleptics) are used to treat schizophrenia and other psychoses; phe-  nothiazines, including chlorpromazine, are the best known. They are  thought to block the activity of the neurotransmitter dopamine in the brain.  Minor tranquilizers (antianxiety agents, or anxiolytics) are used to treat  anxiety and tension; they are usually benzodiazepines, including diaz�  epam (Valium) and chlordiazepoxide (Librium). They have a calming  effect and reduce both physical and psychological effects of anxiety, fear,  and stress by enhancing the action of the neurotransmitter gamma-  aminobutyric acid (GABA) in the brain.</p><p>Trans-Alaska Pipeline or Alaska Pipeline Oil pipeline running  800 mi (1,300 km) north-south across Alaska, U.S. Completed in 1977,  it transports crude oil from the oil fields of Prudhoe Bay on the Arctic  Ocean to an ice-free port at Valdez.

It was completed in 1904, but the impending Japanese  takeover of Manchuria compelled construction of a parallel section within  Russian territory, completed in 1916. The railroad opened large areas of  Siberia to settlement and industrialization by means of spur lines linking  outlying areas with the main line.

Formed in 1930 as Transcontinental &amp; Western Air, Inc.,  from two smaller airlines, the company established the first coast-to-coast  service that same year, flying from Newark, N.J., to Los Angeles in 36  hours. In 1946 TWA began flights between New York City and Paris, and  it expanded by the 1950s to routes through Europe, the Middle East,  Africa, and Asia. It adopted its present name in 1950. Howard R. Hughes  was its principal stockholder and guiding genius from 1939 to 1960-61,  when he lost control to a group of investors. Financially troubled since  the 1980s, TWA continued to operate despite twice landing in bankruptcy  court in the 1990s. It was acquired by AMR, the parent company of  American Airlines, in 2001.</p><p>transcendental argument In philosophy, a form of argument that  is supposed to proceed from a fact to the necessary conditions of its pos�  sibility. A transcendental argument is simply a form of deduction, with  the typical pattern: Only if p then q; q is true; therefore, p is true. As this  form of argument appears in philosophy, the interest, and the difficulty,  reside not in the movement from premises to conclusions, which is rou�  tine, but in the setting up of the major premises�that is, in the kinds of  things that are taken as starting points. For example, Immanuel Kant tried  to prove the principle of causality by showing that it is a necessary con�  dition of the possibility of making empirically verifiable statements in  natural science.</p><p>transcendental function In mathematics, a function not expressible  as a finite combination of the algebraic operations of addition, subtrac�  tion, multiplication, division, raising to a power, and extracting a root.

The Transcendentalists were loosely bound  together by adherence to an idealistic system of thought based on a belief  in the essential unity of all creation, the innate goodness of humankind,  and the supremacy of vision over logic and experience for the revelation  of the deepest truths. Part of the Romantic movement (see Romanticism),  it developed around Concord, Mass., attracting individualistic figures such  as Ralph Waldo Emerson, Henry David Thoreau, AAargaret Fuller, and Bron�  son Alcott. Transcendentalist writers and their contemporaries signaled  the emergence of a new national culture based on native materials, and  they were a major part of the American Renaissance in literature. They  advocated reforms in church, state, and society, contributing to the rise  of free religion and the abolition movement and to the formation of vari�  ous utopian communities, such as Brook Farm. Some of the best writings  by minor Transcendentalists appeared in The Dial (1840-44), a literary  magazine.</p><p>transducer Device that converts one form of energy to another.

The bay at which the transept intersects the nave is  called the crossing. The nave of a church with a cruciform plan usually  extends west from the crossing, the choir and sanctuary east. The arms  of the transept are designated by direction, as northern transept and south�  ern transept.</p><p>transform See Fourier transform, integral transform, Laplace transform</p><p>transformation In mathematics, a rule for changing a geometric fig�  ure or algebraic expression into another, usually accompanied by a rule  for transforming it back. In geometry and topology, a transformation (e.g.,  flipping horizontally or vertically, rotating, or stretching vertically or hori�  zontally) moves each point in a figure or graph to another position. A  graph also undergoes a transformation when its coordinate system is  changed. For example, the equations that establish a correspondence  between the rectangular and polar coordinate systems constitute a trans�  formation. In analysis, a transformation is a procedure that changes one  function into another. Of special interest in many fields of mathematics  are transformations forming a group, in which any two transformations  applied successively produce the same result as another transformation in  the group and each transformation has an inverse transformation (which  undoes it) in the group. See also group theory, integral transform, linear  transformation.</p><p>transformer Device that transfers electric energy from one alternating-  current circuit to one or more other circuits, either increasing (stepping  up) or reducing (stepping down) the voltage. Uses for transformers  include reducing the line voltage to operate low-voltage devices (door�  bells or toy electric trains) and raising the voltage from electric genera�  tors so that electric power can be transmitted over long distances.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1932 I transfusion &#x25BA; transsexualism</p><p>Transformers act through electromagnetic induction; current in the primary  coil induces current in the secondary coil.

Invented at Bell Labs (1947) by John  Bardeen, Walter H. Brattain, and William B. Shockley, it displaced the  vacuum tube in many applications. Transistors consist of layers of differ�  ent semiconductors produced by addition of impurities (such as arsenic  or boron) to silicon. These impurities affect the way electric current moves  through the silicon. Transistors were pivotal in the advancement of elec�  tronics because of their small size, low power requirements, low heat  generation, modest cost, reliability, and speed of operation. Single tran�  sistors were superseded in the 1960s and �70s by integrated circuits;  present-day computer chips contain millions of transistors. Today transis�  tors perform many different functions in nearly every type of electronic  equipment.</p><p>transition element Any chemical element with valence electrons in  two shells instead of only one. This structure gives them their outstand�  ing ability to form ions containing more than one atom (complex ions, or  coordination compounds), with a central atom or ion (often of a transi�  tion metal) surrounded by ligands in a regular arrangement. Theories on  the bonding in these ions are still being refined. The elements in the peri�  odic table from scandium to copper (atomic numbers 21-29), yttrium to  silver (39^17), and lanthanum to gold (57-79, including the ianthanide  series) are frequently designated the three main transition series. (Those  in the actinide series and beyond, 89-111, also qualify.) All are metals,  many of major economic or industrial importance (e.g., iron, gold, nickel,  titanium). Most are dense, hard, and brittle, conduct heat and electricity  well, have high melting points, and form alloys with each other and other  metals. Their electronic structure lets them form compounds at various  valences. Many of these compounds are coloured and paramagnetic (see  paramagnetism) and (as do the metals themselves) often act as catalysts.  See also rare earth metal.</p><p>transitive law Property of relationship that states that if A is in a given  relation to B and B is in the same relation to C, then A is also in that  relation to C. Equality, for example, is a transitive relation.</p><p>Transkei Vtrans-'ka, 'trans-'kl\ Administrative region, South Africa. It  borders the Indian Ocean and Lesotho. It was created by South Africa in  1959 as the first Bantu homeland, a nonindependent black state desig�  nated (together with Ciskei) for the Xhosa-speaking peoples (see Xhosa).  It was made a nominally independent republic in 1976, and all black Afri�  cans with language ties to Transkei (whether or not they lived there) lost  their South African citizenship and became citizens of the new country.  Existing only as an element of the apartheid system, it never received  international recognition. The region was reincorporated into South Africa  in 1994 as part of Eastern Cape and KwaZulu-Natal provinces.</p><p>transmigration of souls See reincarnation</p><p>transmission System in an engine that transmits power generated by  the engine to the point where it is to be used. Most mechanical transmis�  sions function as rotary speed changers; the ratio of the output speed to  the input speed may be either constant (as in a gearbox) or variable. On  variable-speed transmissions, the speeds may be variable in individual  steps (as on an automobile or some machine-tool drives) or continuously  variable within a range. Step-variable transmissions, with some slip, usu�  ally use either gears or chains and provide fixed speed ratios with no slip;  stepless transmissions use belts, chains, or rolling-contact bodies. See  illustration opposite.</p><p>transpiration Loss of water from a plant, mainly through the stomata  (see stoma) of leaves. Darkness, internal water deficit, and extremes of tem�  perature tend to close stomata and decrease transpiration; illumination,  ample water supply, and optimum temperature cause stomata to open and  increase transpiration. Its exact significance is disputed; its roles in pro�  viding the energy to transport water in the plant and in aiding dissipation of  the sun�s heat (by cooling through evaporation of water) have been chal�  lenged. Since stomatal openings are necessary for the exchange of gases,  transpiration has been considered by some to be merely an unavoidable  phenomenon that accompanies the real functions of the stomata.</p><p>transplant or graft Partial or complete organ or other body part  removed from one site and attached at another. It may come from the same  or a different person or an animal. One from the same person�most often  a skin graft�is not rejected. Transplants from another person or, espe�  cially, an animal are rejected unless they are unusually compatible or have  no blood vessels (e.g., the cornea), or if the recipient�s immune reaction is  suppressed by lifelong drug treatment. Transplanted tissues must match (by  blood tests) more closely than blood transfusions. Monoclonal antibodies  targeting the cells that cause rejection hold great promise. Tests are now  under way with monoclonal antibodies that react with antigens present  only on T cells that are participating in rejection, sparing the rest. Rejection  matters less in skin grafts, which may need to last only weeks, and bone  grafts, whose structure remains after the cells die. In bone-marrow trans�  plants, the donor�s marrow cells may attack the recipient�s tissues, often  fatally. Lung transplants have greater chance of success as part of a heart-  and-lung transplant. See also heart transplant, kidney transplant.</p><p>transport In biochemistry, the movement of molecules and particles  across a cell membrane, a selective barrier that allows some substances  (FAT-soluble molecules and some small molecules) to pass and blocks oth�  ers (ions and large, water-soluble molecules). Transport of these vital sub�  stances occurs via several systems. Open channels allow diffusion (passive  transport) of ions directly into cells; facilitators use a chemical change to  help substances diffuse past the membrane; �pumps� force dilute sub�  stances through even when their concentration on the other side is higher  (a form of active transport). Primary active transport is powered directly  by energy released in cell metabolism (see ATP, adenosine triphosphate).  In secondary active transport, a molecule is linked to a different molecule  that carries it across the membrane (cotransport) or is exchanged for a  different molecule crossing in the other direction (countertransport). The  membrane itself opens and closes to let larger particles in or out.</p><p>Transport and General Workers' Union (TGWU) British  labour union. The Dockers� Union (founded 1889) took the lead in the  merger of 14 unions to form the TGWU in 1922. The union grew rapidly  under the leadership of Ernest Bevin (1922-40). As a general union it was  able to enroll workers excluded by the craft unions, and its membership  included workers engaged in transportation industries (except the rail�  roads) as well as in the automotive, construction, chemical, and textile  industries. It exerted a strong influence on British labour policy and was  the largest British union during much of the 20th century, reaching a peak  of more than two million members in the 1970s, though its membership  declined thereafter. See also Labour Party; Trades Union Congress.</p><p>transsexualism Self-identification with one sex by a person who has  the external genitalia and secondary sexual characteristics of the other sex.  Early in life, such a person adopts the behaviour characteristic of the  opposite sex. Surgery and hormone therapy now allow permanent sex  change, a procedure first performed in 1952. The male-to-female opera�  tion is more common because the genital reconstruction is more satisfac�  tory. The male transsexual�s penis and testes are removed and an artificial  vagina created; breasts are created with implants or female sex hormones.</p><p>A four-speed manual transmission.

This transformation is thought to  bring the literal truth of Christ�s presence to the participants. The doctrine  was first elaborated by theologians in the 13th century and was incorpo�  rated into documents of the Council of Trent. In the mid-20th century,  some Roman Catholic theologians interpreted it as referring to a change  of meaning rather than a change of substance, but in 1965 Paul VI called  for the retention of the original dogma.</p><p>transuranium element Any of the chemical elements after uranium  in the periodic table (with atomic numbers greater than 92). All are radio�  active (see radioactivity), with half-lives ranging from tens of millions of  years to fractions of a millisecond. Only two, neptunium (93) and pluto�  nium (94), occur in nature, and only as traces in uranium ores as a result  of neutron irradiation. Transuranium elements with atomic numbers  through 112, along with 114 and 116, have been produced in laboratories.  Each appears to resemble the elements above it in the periodic table; in  particular, the actinides, thorium (90) through lawrencium (103), are simi�  lar to the lanthanides, cerium (58) through lutetium (71). The naming of  the transuranium elements has been fraught with controversy regarding  which laboratory first made the discovery and should propose the name  and whether elements should be named for living persons.

Located  between the Limpopo and Vaal rivers, the region was inhabited c. 1800  chiefly by various Bantu- speaking peoples. The Boers (Afrikaners) began  migrating there during the Great Trek of the 1830s. They established the  short-lived South African Republic in 1856. Discoveries of diamonds and  gold deposits (1868-74) heightened British interest in the region, and the  British annexed the republic in 1877. A Boer rebellion restored it in 1881.  Further discovery of gold in 1886 brought more foreigners, who eventu�  ally outnumbered the Boers. In 1895 Leander Starr Jameson attempted to  incite them to overthrow the Boer government. In 1899 Transvaal joined  with Orange Free State against Britain in the South African (Boer) War. It  was taken in 1900, and in 1902, following the British victory, it became  a crown colony. It was granted self-government in 1906 and joined the  Union (now Republic) of South Africa in 1910. In 1994 the Transvaal  was split into four provinces. The region is extremely rich in mineral and  agricultural resources.</p><p>Transylvania Historic region, northwestern and central Romania. It  comprises a plateau surrounded by the Carpathian Mountains and the Tran�  sylvanian Alps. It formed the nucleus of the Dacian kingdom and was  included in the Roman province of Dacia in the 2nd century ad. The Mag�  yars (Hungarians) conquered the area at the end of the 9th century. When  Hungary was divided between the Habsburgs and the Turks in the 16th  century, Transylvania became an autonomous principality within the Otto�  man Empire. It was attached to Habsburg-controlled Hungary at the end  of the 17th century. Transylvania was the scene of severe fighting in the  Hungarian revolution against Austria in 1848. When Austria-Hungary was  defeated in World War I, the Romanians of Transylvania proclaimed the  land united with Romania. Hungary regained the northern portion during  World War II, but the entire region was ceded to Romania in 1947.</p><p>Trapp family Austrian singers. Maria Augusta Kutschera (1905-87),  the family�s best-known member, was an orphan and novitiate in a Bene�  dictine convent in Salzburg. Later, as a governess, she won the hearts of  the seven children of the widower Baron Georg von Trapp (18807-1947)  and of the baron himself. They married in 1927, had three children, and  later began singing German and liturgical music under the Reverend Franz  Wasner, with whom the family fled in 1938 from Nazi-dominated Aus�  tria to Italy, and finally to Stowe, Vt., U.S. They toured the world to great  acclaim, disbanding in 1955. Their story was the subject of the musical  The Sound of Music (1959; film, 1965).</p><p>trapshooting Shooting sport with moving targets. A shotgun (usually  12-gauge) is used. The targets are clay disks (called pigeons) that are  sprung into the air from a trap. A later variant is skeet shooting. Trapshoot�  ing�s origins date to the 18 th century, when marksmen shot at live pigeons  released from cages or box traps. The modern clay-pigeon variety has</p><p>been included in Olympic Games competition since 1900. A single trap  throws 25 targets at varying angles; each competitor fires four 25-target  rounds.</p><p>Trasimeno X.tra-ze-'ma-noV Lake Lake, Umbria, central Italy.

It is fed by small  streams and has an artificial subterranean outlet (opened 1898) to the Tiber  River. In 217 bc Hannibal defeated a Roman army led by Flaminius there  in the Second Punic War. In World War II it was the scene of severe fight�  ing (1944) between the British and German armies.</p><p>Travancore Vtra-v3n-,kor\ Former princely state, southwestern India.  Now part of Kerala state, it was part of the kingdom of Kerala in the early  centuries ad. In the 11th century it fell under the Cola empire; the Hindu  kings of the Vijayanagar empire held it briefly in the 16th century, after  which it came under Muslim rule. In the mid-18th century it became the  independent state of Travancore; then it was under British protection from  1795. After Indian independence, it merged with Cochin to form the state  of Travancore-Cochin; boundaries were redrawn, and it was renamed Ker�  ala in 1956.</p><p>Traven Vtra-v3n\, B. (b. March 5, 18907, Chicago, Ill., U.S.7�d. March  27, 1969, Mexico City, Mex.) German-Mexican novelist. A recluse, he  refused to disclose to publishers his parentage, nationality, and general  identity, but he may have been forced to leave Germany for his partici�  pation in its short-lived communist revolution in 1919. Most of his books  were written in German. He is noted for adventure stories and as a chroni�  cler of rural life in Mexico, where he settled in the 1920s. Among his  novels are The Treasure of the Sierra Madre (1927; film, 1948) and a  series tracing the lives of impoverished Indians in southern Mexico,  including The Carreta (1931) and The Rebellion of the Hanged (1936).  His works are harsh and his themes compelling, and his lean prose has a  hypnotic immediacy. Much confusion remains about both his life and his  authorship.</p><p>travertine \'tra-v9r-,ten\ Dense, banded rock composed of calcium car�  bonate, CaC0 3 .

Moving to California  in 1944, he quickly rose to prominence on the strength of his guitar style  and for writing and recording honky-tonk classics such as �Divorce Me  C.O.D.� and �No Vacancy� and the coal-mining protest songs �Sixteen  Tons� and �Dark as a Dungeon.�</p><p>treason Offense of attempting to overthrow the government of one�s  country or of assisting its enemies in war. In the U.S., the framers of the  Constitution defined treason narrowly�as the levying of war against the  U.S. or the giving of aid and comfort to its enemies�in order to lessen  the possibility that those in power might falsely or loosely charge their  political opponents with treason.

Treasury bills are usually sold at auction  on a discount basis with a yield equal to the difference between the pur�  chase price and the maturity value. Because they are highly liquid (money  not being tied up in them for long periods of time), their yield rate is nor�  mally lower than that of longer-term securities. Their prices do not usually  fluctuate as much as those of other government securities but may be influ�  enced by the purchase or sale of large quantities of bills by the central bank.  First used extensively during World War I, treasury bills were initially  regarded as an emergency source of revenue, but their flexibility and rela�  tively low interest led to their adoption as a permanent element in the  national debt. From 1970 to 1998 the minimum order for treasury bills was  $10,000, after which it was reduced to $1,000. In 2001 the U.S. Treasury  stopped offering treasury bills with maturities of 52 weeks.</p><p>treaty Contract or other written instrument binding two or more states  under international law.

Located near the village of Treblinka, Pol., it opened in 1941 as  a forced-labour camp. A larger and ultrasecret second camp a mile away,  called T.II, opened in 1942 as an extermination camp for Jews. Victims  were stripped and marched into �bathhouses,� where they were gassed  with carbon monoxide from ceiling pipes. Ukrainian guards and up to  1,500 Jewish prisoner-workers performed the executions. The total num�  ber killed has been estimated at 700,000 to 900,000. In 1943 a group of  prisoner-workers rose in revolt and escaped, but most were soon killed  or recaptured. The T.II camp was closed in October 1943, the labour camp  in July 1944.</p><p>tree Woody perennial plant. Most trees have a single self-supporting  trunk containing woody tissues, and in most species the trunk produces  secondary limbs called branches. Trees provide many valuable products,  especially wood, one of the world�s chief building materials, and wood  pulp, used in papermaking. Wood is also a major fuel source. Trees sup�  ply edible fruits and nuts. In addition, trees take in carbon dioxide and  release oxygen during photosynthesis. Their root systems help retain water  and soil, preventing floods and erosion. Trees and forests provide habi�  tats for a wide variety of animals, and they beautify both natural and  altered landscapes. Growth rings in the trunk indicate the age of most  trees. The tallest trees are the Pacific coast redwoods; the oldest are the  bristlecone pines, some of which are over 4,000 years old.

It was  developed by Sebastien Le Prestre de Vauban in the 17th century for laying  siege to fortresses. Its defensive use was first institutionalized as a tactic  during the American Civil War. It reached its highest development in  World War I. Little used in World War II, it reappeared in the Iran-Iraq  War in the 1980s. A typical construction consisted of two to four parallel  trenches, each dug in a zigzag, protected by sandbags, and floored with  wooden planks. The parallel trenches were connected by a series of com�  munication trenches dug roughly perpendicular to them. The first row was  fronted by barbed wire and contained machine-gun emplacements; the  rear trenches housed most of the troops. Increased use of tanks marked  the end of trench warfare, since tanks were invulnerable to the machine-  gun and rifle fire used by entrenched soldiers.</p><p>Trent, Council of (1545-63) 19th ecumenical council of the Roman  Catholic church, which made sweeping reforms and laid down dogma  clarifying nearly all doctrines contested by the Protestants. Convened by  Pope Paul III at Trento in northern Italy, it served to revitalize Roman  Catholicism in many parts of Europe. In its first period (1545�47) it  accepted the Nicene Creed as the basis of Catholic faith, fixed the canon  of the Old and New Testaments, set the number of sacraments at seven, and  defined the nature and consequences of original sin; it also ruled against  Martin Luther�s doctrine of justification by faith. In its second period  (1551-52) it confirmed the doctrine of transubstantiation and issued  decrees on episcopal jurisdiction and clerical discipline. In the final period  (1562-63) it defined the mass as a true sacrifice and issued statements on  several other doctrinal issues. By the end of the 16th century, many of the  abuses that had motivated the Protestant Reformation had disappeared, and  the church had reclaimed many of its European followers.</p><p>Trent, River River, central England.

On Dec. 25, 1776, George Wash�  ington led his army across the ice-choked Delaware River to attack Hes�  sian troops quartered at Trenton (see battles of Trenton and Princeton). It  served as temporary capital of the U.S. in 1784 and 1799 and was made  the state capital in 1790. The completion of a canal and railroad line in  the 1830s spurred Trenton�s industrial development, and it remains an  industrial city.</p><p>Trenton and Princeton, Battles of (1776-77) Engagements won  by the Continental Army in the American Revolution. Defeats in New York  forced the army under George Washington to retreat through New Jersey  into Pennsylvania. On Dec. 25, 1776, Washington led a force of 6,000  troops across the ice-filled Delaware River to surprise the 1,400-man  British-Hessian force at Trenton, N.J., and captured 900 troops. A British  force of 7,000 troops under Charles Cornwallis arrived to force the Ameri�  can army into retreat. At night Washington led his men around the Brit�  ish to defeat an outpost at Princeton, causing Cornwallis to retreat to New  Brunswick and enabling Washington to lead his troops into winter quar�  ters near Morristown. The victories restored American morale and  renewed confidence in Washington.</p><p>trespass In law, unlawful entry onto land. Trespass was formerly  defined as wrongful conduct causing injury or loss; today it is generally  confined to issues involving real property (see real and personal property).  Once a trespass is proved, the trespasser is usually held liable for any  damages resulting, regardless of whether the trespasser was negligent or  the damage was foreseeable. Criminal trespass, trespass to property that  is forbidden by statute, is punishable as a crime.</p><p>Trevelyan Uri-'vel-yonX, G(eorge) M(acauley) (b. Feb. 16, 1876,  Welcombe, Warwickshire, Eng.�d. July 21, 1962, Cambridge, Cam�  bridgeshire) English historian. He is known for books accessible to gen�  eral readers that often show an appreciation of the Whig tradition in  English thought and reflect a keen interest in the Anglo-Saxon element  in the English constitution. They include three on Giuseppe Garibaldi (1907,  1909, 1911), England in the Age of Wycliffe (1899), British History in the  Nineteenth Century (1782-1901) (1922), History of England (1926), and  The Seven Years of William IV (1952).</p><p>Trevino Uro-'ve-noV Lee (Buck) (b. Dec. 1, 1939, near Dallas, Tex.,  U.S.) U.S. golfer. Of Mexican American descent, Trevino received a  grade-school education, served in the U.S. Marine Corps, and worked as  an odd-job man and assistant professional at golf courses in his native  Texas. In 1967 he unexpectedly came in fifth in the U.S. Open, then won  it the next year. In 1971 Trevino became the first player to win the U.S.,  British, and Canadian Open championships in a single year. He won the  British Open in 1972 and the U.S. PGA Championship in 1974. He then  underwent several back surgeries but returned to win the PGA again in</p><empty-line/><p>Trevithick Vtrev-o-.thikX, Richard (b. April 13, 1771, Illogan, Corn�  wall, Eng.�d. April 22, 1833, Dartford, Kent) British inventor of the first  steam locomotive. With little formal education, in 1790 he became an  engineer for several ore mines in Cornwall. In 1797 his experiments with  high-pressure steam led him to develop a small, light engine to replace</p><p>the large, low-pressure mine engines  then used for hoisting ore. In 1801 he  built the first steam carriage, which  he later drove in London. In 1803 he  built the first steam railway locomo�  tive for an ironworks in Wales. He  abandoned his locomotive projects  in 1808 because the iron rails were  too fragile to carry their weight. He  adapted his engine to produce the  first steam dredger in 1806. In 1816  he traveled to South America to  deliver engines to Peruvian silver  mines, hoping to become wealthy,  but returned to England in 1827 pen�  niless.</p><p>Trevor, William orig. William  Trevor Cox (b. May 24, 1928,</p><p>Mitchelstown, County Cork, Ire.)</p><p>Irish writer. Educated at Trinity Col�  lege, Dublin, he worked as a teacher,  sculptor, and advertising copywriter  before moving to England to write  fiction full-time. His works, noted  for their exquisite characterizations  and finely tuned irony, focus largely  on the psychology of eccentrics and  outcasts. Trevor�s second novel. The  Old Boys (1964), tells the story of an  �old boys� committee whose aging  members plot against each other. His  later novels include Felicia�s Jour�  ney (1994) and Death in Summer  (1998). He is perhaps best known for  his acclaimed collections of wry and  often macabre short stories.</p><p>Triad Term used variously for  secret societies in Qing-dynasty  China (and sometimes earlier), for  modern Chinese crime gangs, and  for crime gangs of other Asian  nationals operating in their own  countries or abroad. A secret society with the name Triad started operat�  ing in the early 19th century in southern China, where it took root and  spread. In the 1850s Triad rebellions threatened Shanghai and Xiamen  (Amoy) and contributed to the revolution of 1911. Chinese secret soci�  eties have in common the swearing of an oath to join, strict rules, a fam�  ily relationship among members, the duty of mutual help, a hierarchy of  functions, and hereditary membership within families.</p><p>triage Vtre-.azh, tre-'azh\ Division of patients for priority of care, usu�  ally into three categories: those who will not survive even with treatment;  those who will survive without treatment; and those whose survival  depends on treatment. If triage is applied, the treatment of patients requir�  ing it is not delayed by useless or unnecessary treatment of those in the  other groups. Triage originated in military medicine, when limited  resources faced many wounded soldiers. It is used in civilian settings dur�  ing disasters or epidemics and in emergency rooms. Triage decisions are  made after relatively quick examination; patients in lower-priority groups  should be reexamined periodically.</p><p>trial In law, a judicial examination of issues of fact or law for the pur�  pose of determining the rights of the parties involved. Attorneys for the  plaintiff and the defendant make opening statements to a judge or jury,  then the attorney for the plaintiff makes his case by calling witnesses,  whom the defense attorney may cross-examine. Unless the case is then  dismissed for lack of sufficient evidence, the defense attorney next takes  a turn calling witnesses, whom the plaintiff�s attorney cross-examines.  Both sides make closing arguments. In a trial before a jury, the judge  instructs the jury on the applicable laws, and the jury retires to reach a  verdict. If the defendant is found guilty, the judge then hands down a sen�  tence.</p><p>trial by ordeal See ordeal</p><p>Richard Trevithick, detail of an oil  painting by John Linnell, 1816; in the  Science Museum, London.</p><p>COURTESY OF THE SCIENCE MUSEUM, LONDON, THE  WOODCROFT BEQUEST</p><p>William Trevor, 1982.</p><p>MARK GERSON</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1936 I triangle &#x25BA; trichinosis</p><p>triangle Geometric figure with three sides and three angles. Each two  sides meet at a point called a vertex, and the three angles sum to 180�. A  triangle with one 90� (right) angle is a right triangle. A triangle with all  sides (and thus all angles) equal is equilateral, one with two sides equal  is isosceles, and one with no two sides equal is scalene. Triangles are par�  ticularly useful in surveying, astronomy, and navigation. Two observation  points (sight lines) form a triangle with a reference object serving as one  vertex and the observation points as the other two. Knowing the angles  of the sight lines and the distance between the observation points allows  the calculation of the lengths of the other sides using the methods of  TRIGONOMETRY.</p><p>Triangle Shirtwaist Co. fire (March 25, 1911) Industrial disaster  that led to the enactment of many safety and labour laws. The fire, which  started in the garment factory on the eighth floor of the Asch Building in  New York City, resulted in the deaths of 146 people, mostly young immi�  grant women. Fire truck ladders, then able to reach only six stories, were  of little help. The sweatshop had few fire escapes, and its doors were  locked to prevent theft, forcing panicked workers to leap from upper-floor  windows. Public outcry also led to new fire codes and child-labour laws  and greater influence for the International Ladies' Garment Workers Union.</p><p>Trianon \,tre-3-'n6n\, Treaty of (June 4, 1920) Treaty at the end of  World War I between Hungary and the Allied Powers, signed at the Tri�  anon Palace at Versailles, France. By its terms, Hungary lost two-thirds  of its former territory, which was divided among Czechoslovakia, Aus�  tria, the future Yugoslavia, and Romania. Hungary�s armed forces were  restricted to 35,000 lightly armed men, to be used only to maintain inter�  nal order.</p><p>Triassic \trl-'a-sik\ Period Interval of geologic time, c. 248-206 mil�  lion years ago, that marks the beginning of the Mesozoic Era. Many new  vertebrates emerged during the Triassic, heralding the major changes that  were to occur in both terrestrial and marine life forms during the Meso�  zoic Era. The seas became inhabited by large marine reptiles. On land,  ancestral forms of various modern amphibians arose, as did reptiles such  as turtles and crocodilians. By the Late Triassic, archosaurs were becom�  ing more and more dominant, and the first true mammals, small shrew�  like omnivores, evolved. Seed ferns dominated the flora of southern  Gondwana, and gymnosperms, including conifers, cycads, and ginkgos,  were common throughout much of Pangea.</p><p>triathlon Endurance contest involving swimming, cycling, and running.  Triathlons originated in California in the 1970s and became an Olympic  event in 2000. Olympic and world championship triathlons consist of a  1.5-km open water swim, a 40-km bicycle ride, and a 10-km run. The  sport�s most famous event, the Ironman triathlon, is held annually in  Hawaii and consists of a 3.8-km (2.4-mi) swim, a 180-km (112-mi)  bicycle ride, and a 42.2-km (26.2-mi) marathon run.</p><p>tribe Any of a variety of social units, including some defined by unilineal  descent and some defined by ethnic origin. Cultural anthropologists now  usually apply the term to a unit of social organization that is culturally  homogeneous and consists of multiple kinship groups�such as the family,  lineage, or can �that prohibit marriages within themselves but endorse or  require marriages with persons of the other kinship groups. (See exogamy  and endogamy.) Most tribes are organized as unitary political entities,  within which people share a common language and culture. Some tribes are  spread across large territories, and individual members may never meet or  know all of the others. Some are small groups, confined to a limited terri�  tory, sometimes a single small island, within which everyone knows every�  one else very well. What unites societies of such diverse scales as being  �tribal� is their own internal sense of �being a single people,� but�  anthropologists would add�a people that lacks the equipment of citizen�  ship, a constitution, or a formalized legal system that would define them as  a nation-state. Throughout most of the history of modem cultural anthro�  pology, the terms tribe and primitive were usually linked; however, in  recent years primitive has been avoided by most anthropologists because it  appears to carry with it an unintended judgment of the moral or techno�  logical development of a people. See also ethnic group.</p><p>tribe (Greek, phylai; Roman, tribus ) In ancient Greece and Rome, any  of a group of political and demographic subdivisions of the population.  In Greece the groups divided into tribes were distinct by location, dialect,  and tradition, and they included the Ionians, Dorians, Achaeans, and Aeto-  lians. In Attica, Cleisthenes replaced the 4 Ionian tribes with 10 new tribes,  each of which was named after a local hero; these came to develop politi�</p><p>cal and civic functions, including the election of magistrates. The demes  developed out of the tribal system. In Rome the tribes formed the 3 (later  4, and still later 35) original divisions of Roman citizens. These were the  basis of military levies, property tax, census taking, and voting units in  political assemblies.</p><p>tribology \tri-'ba-lo-je\ Study of the interactions of sliding surfaces. It  includes three subjects: friction, wear, and lubrication. Many manifesta�  tions of tribology are beneficial and make modem life possible. Many  others are serious nuisances, and careful design is necessary to overcome  problems caused by excessive friction or wear. Friction uses up, or wastes,  a substantial amount of the energy generated by humans; in addition, a  great deal of productive capacity is devoted to replacing objects that have  worn out.</p><p>tribune In ancient Rome, any of various military and civil officials.  Military tribunes were originally infantry commanders. In the early repub�  lic there were six to a legion; some were appointed by consuls or mili�  tary commanders, others elected by the people. During the Roman empire  (from 27 bc), the emperor nominated military tribunes, the office of which  was considered preliminary to a senatorial or equestrian career (see eques ).  Of the civil tribunes, the most important were the tribunes of the plebs  (see plebeian), who were elected in the plebeian assembly. By 450 bc there  were 10 plebeian tribunes, who were elected annually with the right to  intervene in cases of unjust acts of consuls or magistrates by saying �Veto�  (meaning �I forbid it�). The office became powerful; its powers were cur�  tailed by Sul A but restored by Pompey. Under the empire the powers of  the plebeian tribunes passed to the emperor.</p><p>tricarboxylic \ I trI- I kar-bak-'sil-ik\ acid cycle or Krebs cycle or  citric-acia cycle Last stage of the chemical processes by which living  cells obtain energy from foodstuffs. Described by Hans Adolf Krebs in  1937, the reactions of the cycle have been shown in animals, plants,  microorganisms, and fungi, and it is thus a feature of cell chemistry shared  by all types of life. It is a complex series of reactions beginning and end�  ing with the compound oxaloacetate. In addition to re-forming oxaloac-  etate, the cycle produces carbon dioxide and the energy-rich compound  ATP. The enzymes that catalyze each step are located in mitochondria in  animals, in chloropasts in plants, and in the cell membrane in microor�  ganisms. The hydrogen atoms and electrons that are removed from inter�  mediate compounds formed during the cycle are channeled ultimately to  oxygen in animal cells or to carbon dioxide in plant cells.</p><p>Triceratops \tn-'ser-3-,taps\ genus of large, plant-eating ornithischian  dinosaurs of the Late Cretaceous Epoch (99-65 million years ago). Tricer�  atops had a very long skull (some more than 6 ft [1.8 mj long); a large  bony frill about the neck; a relatively short, pointed horn on the nose; a  beaklike mouth; and two pointed horns, more than 3.3 ft (1 m) long, above  the eyes. Adults weighed 4-5 tons (3.6^4.5 metric tons) and grew up to  30 ft (9 m) long. The limbs were very stout, and the hind limbs were more  massive than the forelimbs.</p><p>trichina Uri-'kI-noX Species ( Trichinella spiralis) of parasitic nematode,  found worldwide, that causes the dis�  ease trichinosis. Trichinae (or trichi�  nas), 0.06-0.2 in. (1.5-4 mm) long,  mate in the host�s small intestine.</p><p>Fertilized females penetrate the  intestinal wall and release larvae,  which the blood carries throughout  the body. The larvae grow, mature,  and become encysted within muscle  tissue. The digestive juices of an ani�  mal that eats the muscle tissue break  down the cyst, liberating the larvae  for further development; the worms  mature, and the cycle begins again.</p><p>trichinosis \ 1 tri-ko- , no-s3s\ Disorder caused by the roundworm trichina,  commonly acquired from undercooked infested pork. Larval worms  invade the small intestine, maturing within a week. Fertilized females  deposit new larvae, which are carried by the blood, notably to the muscles  (most often the diaphragm, eyes, throat, and tongue), where they encap�  sulate and may remain alive for years. Though trichinosis usually even�  tually subsides, it may be fatal if the heart and brain are involved. Few  infected persons have sufficient parasites to produce symptoms (includ�  ing diarrhea, nausea, and fever, followed by pain, stiffness, and swelling</p><p>Trichina encysted in muscle</p><p>RUSS KINNE-PHOTO RESEARCHERS/EB INC.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>trichomonad &gt; Trimble I 1937</p><p>of various muscular structures). Anti-inflammatory drugs can relieve  symptoms; thiabendazole may effectively destroy parasites in the intes�  tine. There is no practical way to detect trichinous pork; the surest safe�  guard remains thorough cooking.</p><p>trichomonad \ I tri-k3-'mo- l nad\ Any protozoan of the zooflagellate  order Trichomonadida. Trichomonads have three to six flagella, and they  may have one or multiple nuclei. Most inhabit the digestive systems of  animals. Three species occur in humans: T. hominis in the intestine, T.  vaginalis in the vagina, and T. buccalis in the mouth.</p><p>trickster tale In oral traditions worldwide, a story of deceit, magic,  and violence perpetrated by a mythical animal-human (trickster). The  trickster-hero is both creator god and innocent fool, evil destroyer and  childlike prankster. Coyote, the trickster of tales from American Indian  peoples in California and the Southwest, is one of the most widely known.  In the Pacific Northwest, the trickster is Raven. Many African peoples  also have tales about tricksters (hare, spider, tortoise, etc.), which slaves  brought to the New World. Tales involving the trickster Brer Rabbit were  given literary form by Joel Chandler Harris.</p><p>Trident missile U.S.-made SUBMARINE-Iaunched ballistic missile. The  most advanced Trident missiles, deployed by the U.S. Navy since 1990  and by the Royal Navy since 1994, are more accurate than most land-  based ballistic missiles. Their extended range (up to 7,000 mi [11,300  km]) allows the submarines that carry them to patrol almost anywhere,  making detection extremely difficult. Each missile is capable of carrying  more than 10 multiple independently targeted reentry vehicles (see MIRV),  though arms-control considerations limit the actual number to as few as  three.</p><p>Trieste \tre-'es-ta, tre-'est\ in full Free Territory of Trieste Former  region, western Istria, southern Europe, surrounding and including the city  of Trieste. It was occupied by Yugoslavia in 1945. The UN established it  as a free territory in 1947. It was divided for administrative purposes into  two zones: Zone A in the north, including the city, was under the British  and Americans; Zone B in the south was under the Yugoslavs. In 1954  most of the northern zone was incorporated into Italy; the southern zone  went to Yugoslavia.</p><p>Trieste ancient Tergeste Seaport city (pop., 2001 prelim.: 209,520),  capital of Friuli-Venezia Giulia region, northeastern Italy. It lies at the head  of the Adriatic Sea on the Gulf of Trieste. It was under Roman control  from the 2nd century bc until the collapse of the empire; then it was under  episcopal rule (948-1202). It placed itself in 1382 under Habsburg pro�  tection and later became the prosperous main port of the Austro-  Hungarian Empire. After World War I Trieste was ceded to Italy. Occupied  by Germany in World War II and seized by Yugoslavia in 1945, it became  the centre of the Free Territory of Trieste in 1947. Returned to Italy in 1954,  it became the regional capital in 1963.</p><p>triggerfish Any of about 30 species (family Balistidae) of shallow-  water marine fishes, found world�  wide in tropical seas. Triggerfishes  are deep-bodied, usually colourful  fishes with large scales, high-set  eyes, and three dorsal-fin spines,  which they use for protection. When  a triggerfish is threatened, it darts  into a coral crevice and erects its  large and strong first spine, which it  locks in place with the second (the  �trigger�); when the trigger is later  withdrawn, the first snaps back  down. Though generally considered  edible, some cause food poisoning. The largest grow 2 ft (60 cm) long.</p><p>triglyceride \trl- , gli-s3-,rid\ Any of an important class of naturally  occurring lipids, esters in which three molecules of fatty acids are linked  to glycerol. The three fatty acids may be all the same kind or different  kinds. The types of triglycerides in animals vary with the species and the  fats in their food. In mammals they are stored in adipose tissue until needed  and then broken down to the glycerol and fatty acids. Many vegetable  triglycerides (oils) are liquid at room temperature, unlike those of ani�  mals, and tend to contain a greater variety of fatty acids. In alkali, trig�  lycerides break down to form glycerol and three molecules of soap  (saponification).</p><p>trigonometric function X.tri-go-no-'me-trikV In mathematics, one of  six functions (sine, cosine, tangent, cotangent, secant, and cosecant) that  represent ratios of sides of right triangles. They are also known as the  circular functions, since their values can be defined as ratios of the x and  y coordinates (see coordinate system) of points on a circle of radius 1 that  correspond to angles in standard positions. Such values have been tabu�  lated and programmed into scientific calculators and computers. This  allows trigonometry to be easily applied to surveying, engineering, and  navigation problems in which one of a right triangle�s acute angles and  the length of a side are known and the lengths of the other sides are to be  found. The fundamental trigonometric identity is sin 2 0 + cos 2 0 = 1, in  which 0 is an angle. Certain intrinsic qualities of the trigonometric func�  tions make them useful in mathematical analysis. In particular, their deriva�  tives form patterns useful for solving differential equations.</p><p>trigonometry Mathematical discipline dealing with the relationships  between the sides and angles of triangles. Literally, it means triangle mea�  surement, though its applications extend far beyond geometry. It emerged  as a rigorous discipline in the 15th century, when the demand for accu�  rate surveying techniques and navigational methods led to its use for the  �solution� of right triangles, or the calculation of the lengths of two sides  of a right triangle given one of its acute angles and the length of one side.  The solution can be found by using ratios in the form of the trigonomet�  ric functions.</p><p>Trilling, Lionel (b. July 4, 1905, New York, N.Y., U.S.�d. Nov. 5,  1975, New York, N.Y.) U.S. literary critic and teacher. He taught at  Columbia University from 1931 until his death. His collections of liter�  ary essays include The Liberal Imagination (1950), Beyond Culture  (1965), Sincerity and Authenticity (1972), and Mind in the Modern World  (1972). He was one of the best-known American literary critics of his  time.

Whorls of oval leaves, flower parts,  and fruits are arranged in groups of three. Each solitary white, greenish-  white, yellow, pink, or purple flower is borne on a short stalk that arises  from the whorl of leaves. Many species are cultivated in wildflower gar�  dens. Wild trillium (also called wake-robin or birthroot) is a protected  species.</p><p>trilobite Vtrl-lo-.bltX Any of a group of ovate arthropods (subphylum  Trilobita) that came to dominate the  seas c. 540 million years ago and  became extinct c. 245 million years  ago. Trilobites had a chitinous  exoskeleton and three body lobes: a  raised middle lobe with a lower lobe  on each side. The head, thorax, and  tail were segmented; each segment  bore two appendages. The forward-  most appendages were sense and  feeding organs. Most species had  two compound eyes, though some  were eyeless. Some were predators,  others were scavengers, and still oth�  ers probably ate plankton. Paradox-  ides harlani, found near Boston, grew to 18 in. (45 cm) long and may  have weighed 10 lbs (4.5 kg). Other species were small.</p><p>Trimble, David orig. William David Trimble (b. Oct. 15, 1944,  Belfast, N.Ire.) Former first minister of Northern Ireland and corecipient  with John Hume of the Nobel Prize for Peace in 1998. Trimble was elected  to the British Parliament in 1990 and became leader of the Ulster Union�  ist Party (UUP) in 1995. He represented the UUP in multiparty peace talks  beginning in September 1997. These talks, which included members of  Sinn Fein, the political wing of the Irish Republican Army (IRA), culminated  in the Good Friday Agreement of April 1998, which aimed to restore self-  government in Northern Ireland. Defying opposition from hard-line  unionists, he signed the agreement and successfully campaigned for its  acceptance in referenda in Northern Ireland and in Ireland. In subsequent  elections to the new Northern Ireland Assembly, he was elected first min�  ister.

Scholars consider the trimurti doctrine an  attempt to reconcile different monotheistic approaches with one another  and with the philosophic doctrine of ultimate reality. In trimurti symbol�  ism, the three gods are collapsed into a single form with three faces. Each  god is in charge of an aspect of creation, with Brahma as creator, Vishnu  as preserver, and Shiva as destroyer; however, some sects ascribe all  aspects of creation to their deity of choice. Though sometimes called the  Hindu Trinity, trimurti has little similarity to the Holy Trinity of Chris�  tianity.</p><p>Trinidad and Tobago \ , tri-n3-,dad...t3- , ba-go\ officially Republic  of Trinidad and Tobago Island country, West Indies.

Area: 1,980 sq mi  (5,128 sq km). Population (2005 est.):</p><p>1,298,000. Capital: Port of Spain. The  people are mainly of South Asian or Afri�  can ancestry. Language: English (official). Religions: Christianity (Prot�  estant, Roman Catholic), Hinduism, Islam. Currency: Trinidad and  Tobago dollar. The islands are mostly flat or rolling, with narrow belts of  mountainous highlands and luxuriant rain forests. The Caroni Swamp, an  important bird sanctuary on Trinidad, supports flamingo, egret, and scar�  let ibis populations. The country has large reserves of petroleum and  natural gas, as well as one of the world�s largest supplies of natural  asphalt. Other industries include agriculture, fishing, and tourism. Chief  crops include sugarcane, citrus fruits, cocoa, and coffee. It is a republic  with two legislative houses; its chief of state is the president, and the head  of government is the prime minister. When Christopher Columbus visited  Trinidad in 1498, it was inhabited mostly by Arawak Indians, though there  were probably some Carib speakers as well; Caribs inhabited Tobago. The  islands were settled by the Spanish in the 16th century. In the 17th�18th  centuries African slaves were imported for plantation labour to replace  the original Indian population, which had been decimated by the impact  of slavery and diseases introduced by the Europeans. Trinidad was sur�  rendered to the British in 1797. The British attempted to settle Tobago in  1721, but the French captured the island in 1781 and transformed it into  a sugar-producing colony. The British acquired it in 1802. After slavery  ended in the islands (1834-38), immigrants from India were brought in  to work the plantations. Trinidad and Tobago were administratively com�  bined in 1889. Granted limited self-government in 1925, the islands  became an independent state within the Commonwealth in 1962 and a</p><p>republic in 1976. There occurred some political unrest and in 1990 a failed  Muslim-fundamentalist coup against the government.</p><p>Trinity, Holy In Christian doctrine, the unity of the Father, Son, and  Holy Spirit as one God in three persons. The word Trinity does not appear  in the Bible. It is a doctrine formulated in the early church to interpret  the way God revealed himself, first to Israel, then in Jesus as Saviour, and  finally as Holy Spirit, preserver of the church.

He worked sparingly in the 1980s and �90s because of poor health,  but his role in Three Colours: Red won him acclaim.</p><p>trio sonata Principal chamber music genre of the Baroque era. Despite  its name, it requires four performers: two melody instruments and con-  tinuo (usually a keyboard instrument and a bass instrument). It arose early  in the 17th century as an instrumental version of the Italian vocal-duet  ensemble. The two upper instruments, usually violins, generally wove  their melodic, quasi-vocal lines high above the accompanying parts. Two  standard forms emerged after 1750: the sonata da chiesa, or church  sonata, standardized as a four-movement form (in slow-fast-slow-fast  order); and the suiTE-like sonata da camera, or chamber sonata. By 1770  the genre had been abandoned in favour of the solo sonata.</p><p>Tripitaka Uri-'pi-to-koN Pali Tipitaka Collective term for the three  major divisions of the Pali canon, the canon of Theravada Buddhism. (The  term means �Triple Basket.�) It consists of the Abhidhamma Pitaka, the  Sutta Pitaka, and the Vinaya Pitaka, which were transmitted orally by the  sangha until they were committed to writing about 500 years after the  Buddha�s death. The texts appeared in two languages, Sanskrit and Pali,  the Pali version being the better preserved. Sanskrit versions were trans�  lated into Tibetan, Chinese, and other languages.</p><p>Triple Alliance (1882) Secret agreement between Germany, Austria-  Hungary, and Italy. It provided that Germany and Austria-Hungary would  support Italy if it was attacked by France, that Italy would similarly assist  Germany, and that Italy would remain neutral if Austria-Hungary was  attacked by Russia. The alliance advanced Otto von Bismarck�s efforts to  isolate France. Conflicts between Italy and Austria-Hungary over their  interests in the Balkans led Italy to reach an understanding of neutrality  with France in 1902, which effectively nullified Italy�s pledge to the mem�  bers of the Triple Alliance, though the alliance was renewed in 1907 and  1912. See also Austro-German Alliance.</p><p>Triple Alliance, War of the or Paraguayan War (1864/65-70)  Bloodiest conflict in Latin American history, fought between Paraguay  and the allied countries of Argentina, Brazil, and Uruguay. The Para�  guayan dictator Francisco Solano Lopez (1827-70), objecting to Brazil�s  interference in the politics of neighbouring Uruguay, declared war on  Brazil in 1864. The next year Argentina organized the Triple Alliance with  Brazil and Uruguay. After three years of fighting, the allies annihilated  the Paraguayan forces, but Solano Lopez carried on a guerrilla war until  he was killed. Paraguay was devastated by the war; its population was  reduced by half, and territory covering some 55,000 sq mi (140,000 sq  km) was annexed by Brazil and Argentina.</p><p>Triple Crown In U.S. horse racing, an unofficial championship attrib�  uted to a Thoroughbred horse that in a single season wins the Kentucky  Derby, the Preakness Stakes, and the Belmont Stakes.

Founded c. 700 bc, it became the capital of a federation of three Phoeni�  cian city-states: Sidon, Tyre, and Arvad. It was controlled by the Seleuc-  ids and Romans and taken by the Muslims in the mid-7th century ad.  Besieged and partially destroyed by crusaders in the early 12th century,  it was rebuilt by the later Crusaders (see Crusades). It was occupied by  the Egyptians in the 1830s, the British in 1918, and the British and Free  French in 1941. It became part of the Republic of Lebanon in 1946. It has  sometimes been a centre of Christian-Muslim conflict during Lebanon�s  history. It was also the scene of a siege in 1983 by Palestine Liberation  Organization (PLO) rebels against PLO leader Yasir �Arafat. It is a major  port, a commercial and industrial centre, and a popular beach resort. At  the terminus of an oil pipeline from Iraq, it is an important oil storage and  refining centre.</p><p>Tripoli Arabic Tarabulus al-Gharb Uo-'ra-bo-los-al-'gartA City  (pop. 2003 est.: city, 1,150,000; urban agglom., 2,006,000), capital of  Libya. Located on the Mediterranean Sea, it is the country�s largest city and  chief seaport. Founded by the Phoenicians c. 7th century bc, it was known  as Oea in ancient times and was one of the three cities of the region of  Tripolitania. It was controlled by the Romans from the 1st century bc and  later by the Byzantines. It was taken by the Arabs in 645. Conquered by  the Ottoman Empire in 1551, it was made an Ottoman colonial capital. It  was under Italy�s control (1911�43), after which it was occupied by the  British until Libya�s independence in 1951. U.S. warplanes bombed tar�  gets within the city in 1983 in response to Libya�s alleged support of ter�  rorist activity. Historical structures include numerous mosques and a  Roman triumphal arch. In 1973 Al-Fateh University replaced the former  University of Libya.</p><p>Tripolis \'tri-p3-l3s\ City (pop., 2001: 28,976), southern Greece, the  commercial centre of the central Peloponnese. It was founded in the 14th  century ad as Drobolitza to replace the ancient cities of Pallantium, Tegea,  and Mantinea. Rebuilt in 1770, it became the seat of the local Ottoman  pasha. The city prospered until 1828, when it was destroyed in the War  of Greek Independence. It was rebuilt after 1834.</p><p>Tripolitan \tri-'pa-lo-t 3 n\ War (1801-05) Conflict between the U.S. and  Tripoli. The U.S. refused to continue paying tribute to the rulers of the  North African Barbary Coast states, which had bought immunity from  pirate attacks in the Mediterranean. The pasha of Tripoli demanded greater  tribute and then declared war on the U.S. (1801). A U.S. naval squadron  was sent to Tripolitan waters and fought several skirmishes, including a  raid by Stephen Decatur. A U.S. naval blockade and an overland expedi�  tion from Egypt ended the war with a peace treaty favourable to the U.S.</p><p>Tripolitania \tri-,pa-l9-'ta-ne-9\ Historical region, North Africa. It is  now part of northwestern Libya. Colonized by the Phoenicians in the 7th  century bc, it was named for its three chief cities� Leptis Magna, Oea (Tri�  poli), and Sabrata. It comprised the eastern part of Carthaginian territory  by the 3rd century bc and came under Numidian chieftains in the mid-  2nd century bc. After the Numidian War (46 bc), it was attached to the  Roman province of Africa Nova (see Roman Africa). It fell under the  Islamic caliphate in the 7th century ad and was ruled by successive Arab  and Berber dynasties before becoming part of the Ottoman Empire in  1551. The region gained its independence in 1711. As part of the Barbary  Coast, corsairs operating from there plundered shipping in the Mediter�  ranean Sea, leading to the Tripolitan War with the U.S. (1801-05). It came  under Ottoman administration again in 1835. The Italians acquired the  region in 1912, and it was the scene of fierce fighting between British and  German forces during the North Africa campaigns (1940^-3) of World War  II. In 1951, with the provinces of Cyrenaica and Fezzan, it formed the  independent kingdom of Libya; the provinces were dissolved in 1963.</p><p>Trippe, Juan T(erry) (b.

It is bordered on three sides by Bangladesh and by Mizoram state;  it has an area of 4,049 sq mi (10,486 sq km), and its capital is Agartala.  It was an independent Hindu kingdom for more than 1,000 years before  it became part of the Mughal Empire in the 17th century. After 1808 it  was under the influence of the British government. Tripura became a  union territory in 1956 and acquired full status as a state in 1972. The  main economic activity is agriculture, with rice and jute the major crops.</p><p>trireme \'tri-,rem\ Oar-powered warship. Light, fast, and maneuverable,  it was the principal naval vessel with which Persia, Phoenicia, and the  Greek city-states vied for mastery of the Mediterranean from the Battle  of Salamis (480 bc) through the end of the Peloponnesian War (404). The  Athenian trireme was about 120 ft (37 m) long, and was rowed by 170  oarsmen seated in three tiers along each side; it could reach speeds of  more than 7 knots (8 mph, or 13 kph). Square-rigged sails were used when  the ship was not engaged in battle. Armed with a bronze-clad ram, it car�  ried spearmen and bowmen to attack enemy crews. By the late 4th cen�  tury bc, armed deck soldiers had become so important in naval warfare  that it was superseded by heavier ships.

The hero Tristan goes to Ireland to ask the hand of the princess  Isolde for his uncle, King Mark of Cornwall. On their return the two mis�  takenly drink a love potion prepared for the king and fall deeply in love.  After many adventures, they make peace with Mark, who marries Isolde.  The distraught Tristan goes to Brittany, where he marries another noble  Isolde. When he is wounded by a poisoned arrow, he sends for the first  Isolde. His jealous wife tells him his true love has refused to come; he  dies just before she arrives, and she dies in his arms. The original poem  has not survived, but it exists in many later versions and even became  part of Arthurian legend. Gottfried von Strassburg�s 13th-century version,  considered the masterpiece of medieval German poetry, was the basis for  Richard Wagner�s opera Tristan und Isolde (first performed in 1865).</p><p>Tristano, Lennie orig.

Blind from childhood, Tristano performed and taught in New York  City from the 1940s. His recordings featured players who had studied with  him, including saxophonists Lee Konitz (b. 1927) and Wame Marsh  (1927-87). Although resistant to classification, Tristano�s music displayed  a rigour and virtuosity appropriate to bebop while its aesthetic foreshad�  owed much of cool jazz.</p><p>triticale \,tri-t9-'ka-le\ Wheat-rye hybrid that has a high yield and rich  protein content. The first cross was reported in 1875, the first fertile cross  in 1888. The name triticale first appeared in scientific literature in 1935  and is attributed to Erich Tschermak von Seysenegg. In favourable envi�  ronmental conditions its yield equals that of wheat; under poor conditions  its yield exceeds that of wheat. Its flour is not very suitable for bread�  making but can be blended with wheat flour. Major producers are Rus�  sia, the U.S., and Australia.</p><p>tritium Vtri-te-am, 'tri-she-9m\ Isotope of hydrogen, chemical symbol  written as 3 H or T, with atomic number 1 but ATOMIC weight approximately  3. Its nucleus contains one proton and two neutrons. Tritium is radioactive  (see radioactivity), with a half-life of 12.32 years. Its occurrence in natural  water in an amount 10 -18 that of ordinary hydrogen is believed to be due to  the action of cosmic rays. Some tritium is used in self-luminous materials  (e.g., for watch dials) and as a radioactive tracer in chemical and biochemi�  cal studies. Nuclear fusion of deuterium and tritium at high temperatures  releases enormous amounts of energy. Such reactions have been used in  nuclear weapons and experimental power reactors.

Its surface is covered with enor�  mous expanses of ice sculpted with fissures, puckers, and ridge-crossed  depressions. Geyser-like plumes observed by the Voyager 2 spacecraft may  be gas venting through fissures when the surface is warmed by sunlight.  Triton appears to have formed elsewhere in the solar system and to have  been gravitationally captured by Neptune in the planet�s early history.</p><p>triumph Ancient Roman ritual procession honouring a general who had  won a major battle and killed at least 5,000 of the enemy. Senators and  magistrates were followed by sacrificial animals, captured loot, and cap�  tives in chains. The general, in a purple-and-gold tunic, rode in a chariot,  holding a laurel branch in his right hand and an ivory sceptre in his left,  while a slave held a golden crown over his head. Lastly came the soldiers,  who sang songs. Under the empire only the emperor and members of his  family celebrated triumphs.</p><p>triumphal arch Monumental structure, originating in Rome, pierced  by at least one arched passageway and erected to honour an important  person or commemorate a significant event. It usually spanned a street or  roadway and was built astride the line of march of a victorious army dur�  ing its triumphal procession. Most were built during the empire period.  The basic form consisted of two piers connected by an arch and crowned  by a superstructure, or attic, that served as a base for statues and bore  inscriptions. The large central arch could also be flanked by two smaller  arches. The Roman triumphal arch had a facade of marble columns, and  the archway and sides were adorned with relief sculpture. Among those  built since the Renaissance is the Arc de Triomphe in Paris.</p><p>triumvirate \tri-'9m-vir-9t\ In ancient Rome, usually a board of three  officials who assisted higher magistrates in judicial functions, oversaw  festival banquets, or ran the mint. The First Triumvirate (60 bc) of Pompey,  Julius Caesar, and Crassus was an informal group of three strong leaders  with no sanctioned powers. The Second Triumvirate (43 bc), consisting  of Mark Antony, Lepidus, and Octavian (later Augustus) �formally tresviri  rei publicae constituendae (�triumvirate for organizing the state�)�held  absolute dictatorial power.</p><p>Troas Vtro-,as\ or the Troad Ancient region surrounding the city of  Troy. It consisted mainly of the northwestern projection of Anatolia into  the Aegean Sea. It extended from the Gulf of Edremit to the Sea of Mar�  mara and the Dardanelles and from the Ida mountain range to the Aegean.

The islands are low-lying with coral reefs. The  group has a total land area of about 170 sq mi (440 sq km). The largest,  Kiriwina, is an atoll 30 mi (48 km) long and 3-10 mi (5-16 km) wide,  covered largely with sw&amp; it served as an air and naval base for the  Allies in 1943. Anthropologist Bronislaw Malinowski conducted research  among the Trobriand islanders 1915-18.</p><p>Trobriander Any of the Melanesian people of the Kiriwina (Trobriand)  Islands, lying off eastern New Guinea. Their subsistence is based on yams  and other vegetables, domesticated pigs, and fish. Trobrianders are noted  for their elaborate intertribal trading system, the kula, by which red shell  necklaces are traded between permanent trading partners in a clockwise  direction around a ring of islands; white shell bracelets are traded coun�  terclockwise. Among the Trobrianders, wealth is extremely important as  a sign of power. They were the subject of highly influential studies by  BRONistAW Malinowski.</p><p>Troilus and Cressida \'tr6i-l9s...'kre-si-d9\ Lovers in medieval  romance, based on characters from Greek mythology. In the Iliad, Troilus,  son of Priam and Hecuba, is dead before the Trojan War starts. In non-  Homeric legends he was said to have been killed during the war by Achil�  les. He was first turned into a romantic figure in the Middle Ages, when  he was portrayed as an innocent young lover betrayed by the faithless  Cressida, who abandoned him for the Greek warrior Diomedes. The first  version of the story was written by the 12th-century trouvere Benoit de  Sainte-Maure in the poem �Roman de Troie.� More famous versions  include Giovanni Boccaccio�s �II Filostrato,� Geoffrey Chaucer�s �Troilus  and Criseyde,� and William Shakespeare�s drama Troilus and Cressida.</p><p>Trojan asteroids Two groups of asteroids named for heroes of Greece  and Troy in Homer�s Iliad. These objects revolve around the Sun at the  Lagrangian points (see Joseph-Louis Lagrange) in Jupiter�s orbit. Achil�  les, the first, was discovered in 1906. About 650 are known, but their  actual number is estimated in the thousands. The term Trojan also applies  to objects occupying the corresponding Lagrangian points in the orbits of  other planets. Two such asteroids were discovered in Mars�s orbit in the  1990s.</p><p>Trojan War Mostly legendary conflict between the Greeks and the  people of Troy in western Asia Minor. It was dated by later Greeks to the  12th or 13th century bc. It is celebrated in Homer�s Iliad and Odyssey, in  Greek tragedy, and in Roman literature. In Homer�s account the Trojan  prince Paris ran off with the beautiful Helen, wife of Meneaus of Sparta,  whose brother Agamemnon then led a Greek expedition to retrieve her.  The war lasted 10 years; its participants included Hector, Achilles, Priam,  Odysseus, and Ajax. Its end resulted from a ruse: The Greeks built a large  wooden horse in which a raiding party hid. When the Greeks pretended  to leave, the Trojans brought the horse into the walled city and the Greeks  swarmed out, opening the gates to their comrades and sacking Troy, kill�  ing the men and enslaving the women. The extent of the legend�s actual  historical content is not known; excavations have revealed human habi�  tation from 3000 bc to ad 1200, and there is evidence of violent destruc�  tion about 1250 bc.</p><p>trolley car See streetcar</p><p>Trollope Vtra-tapV Anthony (b.

Beginning in 1844 he pro�  duced 47 novels, writing mainly  before breakfast at a fixed rate of  1,000 words an hour. His best-loved  and most famous works are the six  interconnected Barsetshire novels,  including Barchester Towers (1857)  and The Last Chronicle of Barset  (1867). Depicting the social scene in  an imaginary English county, they  abound in memorable characters and  atmosphere. The Palliser novels,  dealing with political issues and fea�  turing the character Plantagenet Pal�  liser, include the sharply satirical The  Eustace Diamonds (1872). Other  works, such as He Knew He Was  Right (1869), show great psycho�  logical penetration. The Way We Live  Now (1875), with its ironic view of  the Victorian upper classes, is especially highly regarded.</p><p>trombone Brass instrument with an extendable slide with which the  length of its tubing can be increased. It has a mostly cylindrical bore and  a cup-shaped mouthpiece. The slide performs the same function as the  valves in other brass instruments. Valve trombones, both with and with�  out slides, were developed in the early 19th century; they provide  increased agility but diminished tone quality. The trombone exists in sev�  eral sizes; the tenor trombone in B-flat is the standard instrument, but the  bass trombone is also used orchestrally. The trombone (long known as the  sackbut) developed in the 15th century and has changed little over 400  years. By the 16th century it had been adopted by town, court, church,  and military bands; it was employed in early opera orchestras, but it only  began to be used in the symphony orchestra c. 1800. In the 20th century  it became important in dance and jazz bands.</p><p>trompe I'oeil \tro n p-Toei,\ English \,tr6mp-T9i\ French "deceive the  eye" Style of representation in which a painted object is intended to  deceive the viewer into believing it is the object itself.

Tropical cyclones have very low atmospheric pressures in the calm, clear  centre (the eye) of a circular structure of rain, cloud, and very high winds.  In the Atlantic and Caribbean they are called hurricanes; in the Pacific  they are known as typhoons. Because of the Earth�s rotation, tropical  cyclones rotate clockwise in the Southern Hemisphere and counterclock�  wise in the Northern. They may be 50-500 mi (80-800 km) in diameter,  and sustained winds in excess of 100 mph (160 kph) are common. In the  eye, however, the winds drop abruptly to light breezes or even complete  calm.

It arose in the 19th century when European colonial  doctors encountered infectious diseases unknown in Europe. The discov�  ery that many tropical diseases (e.g., malaria, yellow fever) were spread by  mosquitoes led to discovery of other vectors� roles (see sleeping sickness,  plague, typhus) and to efforts to destroy vector breeding grounds (e.g., by  draining swamps). Later, antibiotics came to play an increasingly impor�  tant role. Research institutes and national and international commissions  were organized to control common tropical illnesses, at least in areas with  Europeans. As colonies became independent, their governments took over  most of these efforts, with help from the World Health Organization and  the former colonizing countries.</p><p>troposphere Vtro-po-.sfuA Lowest region of the atmosphere, bounded  by the Earth below and the stratosphere above, with the upper boundary</p><p>being about 6-8 mi (10-13 km) above the Earth�s surface.

The  congress agreed that states having undergone revolutions would be  excluded from the European alliance. They invited the king of the Two  Sicilies to meet at the Congress of Laibach to discuss intervention against  the revolution in Naples. Britain and France did not accept the protocol,  demonstrating the division between the eastern and western members of  the alliance and seriously weakening it.</p><p>Trotsky, Leon orig.

Born to  Russian Jewish farmers, he joined an  underground socialist group and was  exiled to Siberia in 1898 for his revo�  lutionary activities. He escaped in  1902 with a forged passport using  the name Trotsky. He fled to London,  where he met Vladimir Lenin. In 1903,  when the Russian Social-Democratic  Workers' Party split, Trotsky became  a Menshevik, allying himself with  Lenin�s opponents. He returned to  St. Petersburg to help lead the Russian Revolution of 1 905. Arrested and  again exiled to Siberia, he wrote Results and Prospects, setting forth his  theory of �permanent revolution.� He escaped to Vienna in 1907, worked  as a journalist in the Balkan Wars (1912-13), and moved around Europe  and the U.S. until the Russian Revolution of 1917 brought him back to St.  Petersburg (then Petrograd), where he became a Bolshevik and was elected  leader of the workers� soviet. He played a major role in the overthrow of  the provisional government and the establishment of Lenin�s communist  regime. As commissar of war (1918-24), Trotsky rebuilt and brilliantly  commanded the Red Army during the Russian Civil War. Although favoured  by Lenin to succeed him, Trotsky lost support after Lenin�s death (1924)  and was forced out of power by Joseph Stalin. After a campaign of denun�  ciation, he was expelled from the Politburo (1926) and Central Commit�  tee (1927), then banished from Russia (1929). He lived in Turkey and  France, where he wrote his memoirs and a history of the revolution. Under  Soviet pressure, he was forced to move around Europe and eventually  found asylum in 1936 in Mexico, where, falsely accused in the purge tri�  als as the chief conspirator against Stalin, he was murdered in 1940 by a  Spanish communist.</p><p>Trotskyism Marxist ideology based on the theory of permanent revo�  lution first expounded by Leon Trotsky. Trotsky believed that because all  national economic development was affected by the laws of the world  market, a revolution depended on revolutions in other countries for per�  manent success, a position that put him at odds with Joseph Stalin�s  �socialism in one country.� After Trotsky�s exile in 1929, Trotskyists  continued to attack the Soviet bureaucracy as �Bonapartist� (based on the  dictatorship of one man). In the 1930s Trotskyists advocated a united front  with trade unions against fascism. After Trotsky�s murder (1940), Trotsky�  ism became a generic term for various revolutionary doctrines that  opposed the Soviet form of communism.

They wrote in the langue  d�oc of southern France (see Languedoc) and cultivated a lyric poetry  intricate in metre and rhyme and usually of a romantic amatory strain  reflecting the ideals of courtly love. Favoured at courts, troubadours had  great freedom of speech and were charged with creating around the court  ladies an aura of pleasant cultivation. Their poetry, often set to music,  was to influence all later European lyrical poetry.

After  the death of Fyodor I and the end of the Rurik dynasty (1598), the boyars  opposed the rule of Boris Godunov and after his death placed the noble�  man Vasily Shuysky (1552-1612) on the throne in 1606. Shuysky�s rule  was weakened by revolts, challenges by the second False Dmitry, and the  invasion of Russia by the Polish king Sigismund III Vasa in 1609-10. The  Russians finally rallied against the Polish invaders and succeeded in oust�  ing them from their control of Moscow in 1612. A new representative  assembly met in 1613 and elected Michael Romanov as tsar, commencing  the 300-year reign of the Romanov dynasty.</p><p>trout Any of several prized game and food fishes of the family Salmo-  nidae, native to the Northern Hemisphere but widely introduced else�  where. Though most species inhabit cool fresh waters, a few (called sea  trout; e.g., cutthroat trout) migrate to the sea between spawnings. Some  weakfish are also called sea trout. The genus Oncorhynchus includes  salmon and several trout species; Salvelinus contains trout species  regarded as chars. Trout species vary greatly in anatomy, colour, and hab�  its. Most live among submerged objects or in riffles and deep pools, eat�  ing insects, small fishes and their eggs, and crustaceans.

Trouveres were the counterparts  in the language of northern France (the langue d�oil ) to the Provencal  troubadour. Of either aristocratic or humble origins, they were originally  connected with feudal courts but later found middle-class patrons. Noted  for such forms as the chanson de geste, their works are generally narra�  tives; their basic subject was courtly love. Trouveres pleased their audi�  ences by combining stylized themes and traditional metrical forms rather  than by originality of expression. The lyrics were intended to be sung, by  the poet alone or accompanied by a hired musician.</p><p>Trowbridge \'tro-,brij\ Town (pop., 1995 est.: 30,000), county seat of  Wiltshire, southern England.

The town is  famous for its fine woolen cloth.</p><p>Troy or Ilium Ancient city in Troas, northwestern Anatolia. It holds an  enduring place in both literature and archaeology. In literature, it is well  known as the location of the Trojan War. The archaeological site, a huge  mound at modern Hisarhk, Tur., on the Menderes (Scamander) River, was  first excavated by archaeologist Heinrich Schliemann (1870-90). It consists  of nine major layers dating from the early Bronze Age to Roman times  (c. 3000 Bc-4th century ad). In Greek legend, the city was besieged by  the Greeks for 10 years and finally destroyed. Its story is told in Homer�s  Iliad and Odyssey and in Virgil�s Aeneid. Whether the site is the actual  city of these works is still debated, but the archaeological evidence indi�  cates that a city (Troy Vila) was destroyed at that location c. 1260�40 bc  and likely was the Homeric Troy. The ruins were designated a UNESCO  World Heritage site in 1998.</p><p>Trubetskoy \,tru-byit-'sk6i\, Nikolay (Sergeyevich) (b. April 16,  1890, Moscow, Russia�d.

One of the founders of the Pra�  gue school of linguistics, he was noted as the author of the school�s most  important work on phonology, Principles of Phonology (1939). Influenced  by Ferdinand de Saussure, Trubetskoy redefined the phoneme functionally  as the smallest distinctive unit within the structure of a language. He died  of a heart attack after being persecuted by the Nazis for criticizing racist  theory.</p><p>Truce of God Measure by the medieval Roman Catholic Church to  suspend warfare on certain days of the week and for certain church fes�  tivals and Lent. It was instituted in France as early as 1027, and else�  where in Europe (excluding England) during the next several decades.  The popes later took its direction into their own hands, and the first decree  of the Council of Clermont (1095) proclaimed a weekly truce for all  Christendom, with an oath of adherence to be taken by all men over age  12. The truce was most powerful in the 12th century but was never entirely  effective.</p><p>Trucial States See United Arab Emirates</p><p>truck or lorry Motor vehicle designed to carry freight or heavy articles.

Gasoline  engines for trucks were common until the 1940s, when diesel engines gen�  erally replaced them. Trucks may be either straight (all axles attached to  the frame) or articulated (two or more frames connected by couplings);  large articulated trucks consist of a towing tractor and a connected semi�  trailer. Air brakes were added to trucks in 1918 and four-wheel brakes in  1925; later improvements included power steering.</p><p>Trudeau, Pierre (Elliott) (b. Oct. 18, 1919, Montreal, Que., Can.�d.  Sept. 28, 2000, Montreal) Prime minister of Canada (1968-79, 1980-84).  He practiced law before being elected to the Canadian House of Com�  mons (1966-84). He was minister of justice (1967-68) in Lester Pearson�s  administration. He became leader of the Liberal Party and prime minis�  ter in 1968. A determined antiseparatist, he advocated a strong federal  government and took a determined stand against separatist terrorists. After  nine months out of office, he returned in 1980 to initiate reforms that  called for the constitutional �patriation,� or transfer, of the amending  authority from the British Parliament to Canada. To this end, he effected  passage of the Canada Act, which precipitated Canada�s official indepen�  dence from Britain. His term saw the adoption of official bilingualism. He  spent his final years in office seeking greater economic independence for  Canada, forming better trade relations between industrialized democra�  cies and developing countries, and urging further international disarma�  ment talks. He resigned as leader of the Liberal Party and retired from  politics in 1984, by which time he was the longest-serving leader of any  Western democracy.</p><p>Truffaut \tnE-'fb,\ English \tru-'fo\, Francois (b.

As a film critic for the avant-garde Cahiers du Cinema,  he advocated the auteur theory and helped establish the New Wave move�  ment. His first feature film was the semi-autobiographical The 400 Blows  (1959), a portrait of a delinquent boy, that won him international acclaim.  Influenced by Jean Renoir and Alfred Hitchcock, he made varied and  admired movies such as Shoot the Piano Player (1960), Jules and Jim  (1961), Fahrenheit 451 (1966), Stolen Kisses (1968), The Wild Child  (1969), Day for Night (1973, Academy Award), The Story of Adele H.

His films record life�s grayness and  flatness with a sense of resignation quite distinct from platitude or petu�  lant nihilism.</p><p>truffle Edible, underground fungus in the genus Tuber (class Asco-  mycetes, division Mycota), prized as  a food delicacy since antiquity.</p><p>Native mainly to temperate regions,  truffles flourish in open woodlands  on calcium-rich soil. The different  species range from pea-sized to  orange-sized. Truffles usually are  associated with tree roots and are  found up to about 1 ft (30 cm) below  the soil surface. Experienced gather�  ers occasionally detect mature  truffles by scent or by the morning  and evening presence of hovering  columns of small yellow flies, but  more often with the help of trained pigs or dogs. The truffle is important  in French cookery, and truffle gathering is an important industry in France.  Truffles are among the most highly valued foods in the world.

Dec. 26,  1972, Kansas City, Mo.) 33rd president of the U.S. (1945-53). He worked  at various jobs before serving with distinction in World War I. He became  a partner in a Kansas City haberdashery; when the business failed, he  entered Democratic Party politics with the help of Thomas Pendergast. He  was elected county judge (1922-24), and he later became presiding judge  of the county court (1926-34). His reputation for honesty and good man�  agement gained him bipartisan support. In the U.S. Senate (1935-45), he  led a committee that exposed fraud in defense production. In 1944 he was  chosen to replace the incumbent Henry Wallace as the Democratic Party  vice presidential nominee, and he won election with Pres. Franklin D.  Roosevelt. After only 82 days as vice president, he became president on  Roosevelt�s death (April 1945). He quickly made final arrangements for  the San Francisco charter-writing meeting of the UN, helped arrange Ger�  many�s unconditional surrender on May 8, which ended World War II in  Europe, and in July attended the Potsdam Conference. The Pacific war  ended officially on September 2, after he ordered atomic bombs dropped  on Hiroshima and Nagasaki; his justification was a report that 500,000 U.S.  troops would be lost in a conventional invasion of Japan. He announced  what would become known as the Truman Doctrine, which entailed aid for  Greece and Turkey (1947); established the Central Intelligence Agency; and  pressed for passage of the Marshall Plan to aid the economic recovery of  western Europe. In the 1948 presidential election he defeated Thomas  Dewey despite widespread expectation of his own defeat. On July 26,  1948, Truman issued an executive order banning segregation in the armed  forces. He initiated a foreign policy of containment to restrict the Soviet  Union�s sphere of influence, pursued his Point Four Program, and initi�  ated the Berlin airlift (see Berlin blockade and airlift) and the NATO pact  of 1949. He sent troops under Gen. Douglas MacArthur to fight in the  Korean War. Problems of pursuing the war occupied his administration  until he retired. Though he was often criticized during his presidency, his  reputation grew steadily in later years.</p><p>Truman Doctrine Pronouncement by Pres. Harry Truman. On March  12, 1947, he called for immediate economic and military aid to Greece,  which was threatened by a communist insurrection, and to Turkey, which  was under pressure from Soviet expansion in the Mediterranean. Engaged  in the Cold War with the Soviet Union, the U.S. sought to protect those  countries from falling under Soviet influence after Britain announced that  it could no longer give them aid. In response to Truman�s message, Con�  gress appropriated $400 million in aid.</p><p>Trumbull, John (b. June 6, 1756, Lebanon, Conn.�d.

Jonathan Trumbull (1710-85), he served as an aide to George Washing�  ton during the American Revolution and later as secretary to John Jay in  London. In 1784 he studied painting in London with Benjamin West, and  with West�s encouragement he began the celebrated series of historical  paintings and engravings he would work on throughout his life.

An economic slump in the late 1980s forced him to cede par�  tial control of his properties to creditors, but his fortunes rebounded in the  1990s, and he embarked on a vast building project on New York�s West  Side. His political ambitions and enjoyment of publicity combined to keep  him in the public eye.</p><p>trumpet Brass instrument with tubing twice-folded in an elongated  shape. (In its broad sense, trumpet may refer to any lip-vibrated instru�  ment.) The modern trumpet has a mostly cylindrical bore, three valves,  and a cup-shaped mouthpiece, and it is usually a B-flat or C instrument.  The trumpet had taken its basic modem shape, with its ovoid loop, by c.  1500. In the 17th�18th centuries it employed crooks (removable lengths  of tubing) to enable playing in different keys. The valved trumpet was</p><p>developed in the 1820s. The trumpet has been associated with ceremo�  nial and military uses since the 16th century. It joined the standard orches�  tra by c. 1700, though it was only selectively used, usually with the  timpani. Its brilliant sound has since made it indispensable in a wide vari�  ety of ensembles.

Aug. 31, 1941, Yelabuga) Russian poet. After spend�  ing most of her youth in Moscow, she began studies at the Sorbonne in  Paris at age 16. She published her first poetry collection in 1910. Her  verses on the Russian Revolution glorify the anti-Bolshevik resistance, of  which her husband was a part. She lived abroad from 1922 to 1939, mostly  in Paris, writing varied works including poetry that increasingly reflected  nostalgia for her homeland. Many of her best and most typical poetic  qualities are displayed in the long verse fairy tale Tsar-devitsa (1922;  �Tsar-Maiden�). Separated from her husband and daughter and isolated  from friends after the evacuation of Moscow, she committed suicide.  Though little known outside Russia, she is considered one of the finest  20th-century poets in Russian.</p><p>Tswana Vtswa-noV Westerly division of the Sotho peoples of South  Africa and Botswana. The Tswana, numbering 4.1 million, live in a grass�  land environment in which they raise livestock and grow com and sor�  ghum. There is a seasonal migration of Tswana men, many of whom work  in the mining and industrial centres of South Africa.</p><p>Tu Fu See Du Fu  t'u-ti See tudi</p><p>Tuamotu X.tu-o-'mo-tiA Archipelago Group of about 80 islands  (pop., 1996: 14,283), French Polynesia. The archipelago comprises 75  atolls, one raised coral atoll (Makatea), and innumerable coral reefs,  roughly dispersed northwest-southeast as a double chain for over 900  miles (1,450 km). Europeans visited the islands in the 16th�17th centu�  ries. France occupied them in 1844 and annexed them in 1880 as a Tahi�  tian dependency. They now form, with the Gambier Islands, an  administrative division of French Polynesia. In 1947 Thor Heyerdahl�s  Kon-Tiki expedition ended on Raroia�one of Tuamotu�s many reefs.  France has used some uninhabited atolls in the archipelago for nuclear  testing.</p><p>Tuareg Vtwa-,reg\ A member of a nomadic Berber-speaking people of  the southwestern Sahara in Africa. Their feudal, matrilineal culture  divides society into nobles, clergy, vassals, artisans, and labourers (once  slaves). Northern Tuareg live mainly in true desert; southern Tuareg live  in steppe and savanna. They have traditionally engaged in herding, agri�  culture, convoying caravans across their territories, and raiding neigh�  bouring tribes. They combine many pre-Islamic rituals and customs with  Sunnite Muslim beliefs. Droughts in the 1970s and �80s reduced their  numbers and eroded their traditional way of life.</p><p>tuatara \ l tii-9- , ta-ra\ Either of two species ( Sphenodon punctatus and S.  guntheir) of lizardlike, nocturnal reptiles of the order Rhynchocephalia,  found on certain islets of New Zealand. Up to 2 ft. (60 cm) long and  weighing over 2 lbs (1 kg), tuataras have two pairs of well-developed  limbs, a scaly crest down the neck and back, a third eyelid that closes  horizontally, and a pineal eye between the two normal eyes. A bony arch  behind the eyes distinguishes tuataras from lizards. They eats insects,  other small animals, and birds� eggs. In spring, they lay 8-15 eggs away  from their burrow. Tuataras may live about 100 years.</p><p>Tuatha De Danann \ , tu-9-h3- , d y a- , da-n3n\ In Celtic mythology, a race  inhabiting Ireland before the arrival of the Milesians, the ancestors of the  modern Irish. Skilled in magic, they were banished from heaven because  of their knowledge and descended on Ireland in a cloud of mist. They  were thought to have disappeared into the hills when overcome by the</p><p>Milesians. They were regarded as actual people by native historians up  to the 17th century. Representative of the Celtic pantheon, they have  become associated in popular legend with the numerous fairies still said  to inhabit the Irish landscape.</p><p>tuba Deep-pitched valved brass instrument with a widely expanding coni�  cal bore. Tubas vary in size and pitch. The tubing is coiled in an oblong  shape, and the bell points upward or forward. Patented in Berlin in 1835,  the tuba displaced the ophicleide to become the foundation of the brass  section in the orchestra and in military and brass bands.

His first  musical influence was the yodeling of Jimmie Rodgers. He became one of  the earliest exponents of honky-tonk with hits such as �I�m Walking the  Floor over You� (1941). He joined the Grand Ole Opry in 1942, and he  became one of the first musicians to record in Nashville. He was a pio�  neer of the electric guitar in the early 1950s. His Nashville radio program,  Midnight Jamboree (from 1947), helped launch many stars, including the  Everly Brothers and Elvis Presley. In 1947 he starred in the first country  music show at Carnegie Hall.</p><p>tube worm Any of numerous species of sedentary, solitary or colonial,  marine worms that spend their entire life in a tube made from special  secretions or from sand grains glued together. Found worldwide, tube  worms range from less than an inch (25 mm) to more than 20 ft (6 m)  long. The bottom of the tube is attached to the seafloor; the mouth and  tentacles are at the upper, open end. The worm breathes through gills, the  tentacles, or the body wall. The tentacles, variously arranged, are used to  filter-feed aquatic plants and animals. Tube worms occur in the annelid  class Polychaeta and in the phyla Phoronida and Pogonophora. Many,  mostly unnamed, forms live in deep-ocean vent communities.</p><p>tuber Short, thickened, mostly underground stem that constitutes the  resting stage of certain seed plants. It is often an organ of food storage,  reproduction, or both. It bears minute scale leaves, each with a bud that  has the potential for developing into a new plant. The common potato is  a typical tuber; the much-reduced leaves and associated buds form its  �eyes.� The term is also used imprecisely but widely for fleshy roots or  rhizomes that resemble tubers (e.g., the �tuber� of the dahlia, actually a  tuberous root).</p><p>tuberculosis Uu-.bor-kyo-'lo-sosV (TB ) formerly consumption Bac�  terial disease caused by some species of mycobacterium (tubercle bacillus).  Mentioned in ancient Egyptian records and by Hippocrates, it has occurred  throughout history worldwide. In the 18th�19th centuries it reached near�  epidemic proportions in the rapidly industrializing and urbanizing West�  ern world, where it was the leading cause of death until the early 20th  century. TB resurged in the 1980s, spreading from AIDS patients to oth�  ers, especially in prisons, homeless shelters, and hospitals, since enclosed  settings promote spread. It occurs worldwide and is still a major cause of  death in many countries. The body isolates the bacilli by forming tiny  tubercles (nodules) around them. This often arrests TB�s progress and no  symptoms occur, but if the disease is not treated, it may become active�  and contagious�later in life, most often when the immunity of the  infected individual is suppressed (e.g., AIDS, after organ transplant). The  original tubercle breaks down, releasing still viable bacilli into the blood�  stream to cause a new infection, which starts with loss of energy and  weight and persistent cough. Health deteriorates, with increasing cough  and possibly pleurisy (see thoracic cavity) and spitting up blood. Grow�  ing tubercle masses may destroy so much lung tissue that respiration can�  not supply the body with enough oxygen. Other organs can be affected,  with complications including meningitis. A vaccine with weakened bacte�  ria has helped control infection, but preventing exposure by recognizing  and treating active TB early is more effective. Because many strains are  resistant to drugs, treatment requires at least two drugs to which the  patient�s strain is sensitive and at least six months; inadequate treatment  lets resistant bacilli multiply. The acute disease caused by multidrug-  resistant strains is very hard to cure and usually fatal.</p><p>Tubman, Harriet orig. Arminta Ross (b. c. 1820, Dorchester  county, Md., U.S.�d.

In 1700 the Spanish founded several missions  nearby, and in 1776 the small walled pueblo of Tucson was made a Span�  ish presidio (fort). It remained the province�s military headquarters under  Mexican rule. The U.S. acquired the territory through the Gadsden Pur�  chase (signed in 1853). Tucson was the territorial capital from 1867 to  1877. It grew with the arrival of the railroad in 1880 and the discovery  of silver at nearby Tombstone and copper at Bisbee. Its dry, sunny climate  and desert locale have made it a popular tourist and health resort and  retirement community. It is the seat of the University of Arizona (1885).</p><p>Tucuna or Ticuna or Tikuna \t3-'ku-nos\ South American Indian  people living in Brazil, Peru, and Colombia. Traditional Tucunas live in  the rainforest of the northwestern Amazon basin, cultivating cassava and  com (maize), raising chickens, and hunting and gathering in the forest.  They make baskets, pottery, and bark cloth and trade animal hides and  handmade canoes for money and manufactured goods. They were once  skilled hunters with blowguns, spears, and snares, but depletion of ani�  mal populations has altered old hunting patterns.</p><p>Tudjman \'tuj-man\, Franjo (b. May 14, 1922, Veliko Trgovisce, King�  dom of Serbs, Croats, and Slovenes�d. Dec. 10, 1999, Zagreb, Cro.)  Croatian politician and president of Croatia (1990-99). He served with the  partisans under Marshal Tito in World War II. He taught political science  and history at the University of Zagreb (1963-67) and later wrote numer�  ous books on history and politics. He was expelled from the Yugoslav  Communist Party in 1967 for his nationalist writings, and he was impris�  oned in 1972 and 1981. In 1989 Tudjman founded the Croatian Democratic  Union, which won Croatia�s first free parliamentary elections in 1990.  Named president, he pressed for the creation of a homogenous Croatian  state. When Serbian areas of Eastern and Western Slavonia and the Krajina  revolted, they were occupied by the Yugoslav army. Beginning in 1995,  Tudjman reasserted control over these areas and established virtual control  over portions of Bosnia and Herzegovina with majority Croatian popula�  tions. His authoritarian style, along with his refusal to cooperate with the  International Criminal Tribunal for the Former Yugoslavia, led to the inter�  national isolation of Croatia, and his excesses in the Bosnian conflict and  his autocratic rule earned Tudjman a reputation for brutality.</p><p>Tudor, Antony orig. William Cook (b. April 4, 1908, London,  Eng.�d. April 20, 1987, New York, N.Y., U.S.) British-born U.S. dancer,</p><p>teacher, and choreographer. In 1927 he joined Marie Rambert�s company,  where he choreographed and danced such works as The Planets (1934)  and The Lilac Garden (1936). In 1940 he moved to New York City, join�  ing the new Ballet Theatre (later American Ballet Theatre), for which he  created many of his signature psychological ballets, including Pillar of  Fire (1942) and Shadow of the Wind (1948). In these works he sought to  convey emotional conflict and aspects of character and motivation. In  1974 he became associate director of American Ballet Theatre.</p><p>Tudor, Henry See Henry VII (England)</p><p>Tudor, house of English royal dynasty that gave five sovereigns to  England (1485-1603). The Tudors originated in the 13th century, but the  dynasty�s fortunes were established by Owen Tudor (c. 1400-61), a Welsh  adventurer who took service with Henry V and married Henry�s widow,  Catherine of Valois (1401-37). Owen and Catherine�s son Edmund Tudor  (c. 1430-56) was created earl of Richmond and married Lady Margaret  Beaufort (1443-1509), a descendant of John of Gaunt of the house of  Lancaster. Their son Henry Tudor claimed the English throne as Henry VII  in 1485 and cemented his claim with his marriage to Elizabeth of the  house of York, daughter of Edward IV. The Tudor rose symbolized the  union between the red rose of the Lancastrians and the white rose of the  Yorkists. The Tudor dynasty continued in the 16th century with the reigns  of Henry VIII and his children Edward VI, Mary I, and Elizabeth I. In 1603  the dynasty was succeeded by the house of Stuart.</p><p>Tudor, Margaret See Margaret Tudor</p><p>Tudor, Mary See Mary I</p><p>Tudor style Architectural style in England (1485-1558) that made lav�  ish use of half-timbering (see timber framing), as well as oriels, gables,  decorative brickwork, and rich plasterwork.

The original palace, com�  missioned by Catherine de Medicis, was begun in 1564 by Philibert Delorme  (c. 1515-1570); the next 200 years saw numerous additions and alter�  ations by Jean Bullant (15207-1578), Jacques du Cerceau (c. 1520-1585),  Louis Le Vau (1612-1670), and others. The Tuileries Gardens have  changed little since Andre Le Notre redesigned them in 1664. His design  extended the central walkway beyond the gardens and out into the coun�  tryside to the hilltop west of the palace, where the Arc de Triomphe now  stands.</p><p>Tukhachevsky \,tuk-9-'chef-ske\, Mikhayl (Nikolayevich) (b.</p><p>Feb. 16, 1893, near Slednevo, Russia�d.

Because of extended contacts with the Fulani, the Tukulor speak a dialect  of Fula, an Atlantic language of the Niger-Congo family. In the 10th�  18th centuries they were dominated by a succession of non-Tukulor  groups in the kingdom of Tekrur. About 1850 they established an empire  and conquered the Bambara kingdoms of Kaarta and Segu and extended  their empire to Timbuktu before it was destroyed by the French in 1890.  Today the Tukulor raise livestock, fish, and cultivate millet and sorghum.</p><p>Tula Ancient city in Mexico, the capital of the Toltecs, which flourished  in the 10th� 12th centuries. Its exact location is uncertain; the archaeo�  logical site now designated Tula, near the town of that name in Hidalgo  state, has been the choice of historians, but other scholars identify Tula  with what is now usually called Teotihuacan. The Tula site suggests a city  that had a population in the tens of thousands. The major civic centre con�  sists of a plaza bordered by a five-stepped pyramid, two other pyramids,  and two ball courts. Tula�s art and architecture are strikingly similar to  those of the Aztec capital, Tenochtitlan, and its artistic themes suggest that  the Aztecs� concept of themselves as warrior-priests of the sun god was  borrowed directly from Tula.</p><p>tulip Any of almost 4,000 varieties of about 100 species of cultivated  bulbous herbaceous plants making up the genus Tulipa in the lily family,  native to Eurasia. Among the most popular of all garden flowers, the tulip  produces two or three thick, bluish-green leaves clustered at the base of  the plant. The usually solitary inverted bell-shaped flowers have three  petals and three sepals. Colors range from white through yellows and reds  to brown and deep purple to almost black. Streaked blossoms get their  streaks from a harmless virus infection that causes the color to disappear  in patterns, letting white or yellow show through.</p><p>tulip tree or tulip poplar or yellow poplar Lofty North Ameri�  can ornamental and timber tree ( Liriodendron tulipifera) of the magnolia  family, not related to true poplars. It occurs in mixed hardwood stands in  eastern North America. It is taller than all other eastern broad-leaved trees  (up to 197 ft, or 60 m), and its trunk often has a diameter greater than 7  ft (2 m). Long-stemmed, bright-green leaves have two to four side lobes  and blunted tips. Yellowish-green tuliplike flowers have six petals, orange  at their bases, and three bright-green sepals. Other characteristics include  conelike clusters of winged fruits; aromatic, purplish-brown twigs; stun�  ning golden-yellow autumn leaves; winter buds resembling a duck�s bill;  and resistance to pests and diseases. The wood is used to manufacture  furniture parts, plywood panels, paper, boxes, and crates.</p><p>Tull, Jethro (b. 1674, Basildon, Berkshire, Eng.�d. Feb. 21, 1741,  Prosperous Farm, near Hungerford, Berkshire) British agronomist and  inventor. He was educated at Oxford. Around 1701 he perfected a horse-  drawn seed drill that economically sowed the seeds in neat rows, and later  a horse-drawn hoe. He stressed the use of manure and the importance of  breaking up the soil into small particles. Tull�s methods, though initially  attacked, were eventually adopted by many large landowners, and they  helped form the basis of modern agriculture.</p><p>Tulsa City (pop., 2000: 393,049), northeastern Oklahoma, U.S. On the  Arkansas River, Tulsa originated in 1836 as a settlement of Creek Indian  immigrants; white settlement began in 1882 after the arrival of the railway.  The discovery of oil nearby in the early 20th century launched an oil and  gas boom, and phenomenal growth followed. Many major oil companies  now have plants and offices in the city. It is the head of navigation for the  Arkansas River Navigation System, a waterway that stretches 440 mi (708  km) to the junction of the Arkansas and Mississippi rivers. The commercial  and financial centre of a rich agricultural area, it is the seat of the University  of Tulsa (1894) and Oral Roberts University (1965).</p><p>tumbleweed Plant that breaks away from its roots and is driven about  by the wind as a light rolling mass, scattering seeds as it goes. Examples  include pigweed (. Amaranth retroflexus, a widespread weed in the west�  ern U.S.) and other amaranths, tumbling mustard, Russian thistle, the  steppe plant Colutea arborea, and the grass Spinifex of Indonesian shores  and Australian steppes.</p><p>Tumen Vtu-'monV River River, eastern Asia. It forms the northeastern  frontier of North Korea with China and Russia. It originates on Mount</p><p>Paektu, North Korea�s highest mountain, and flows generally north and  northeast before turning southeast to enter the Sea of Japan (East Sea). It  is 324 mi (521 km) long but navigable for only 53 mi (85 km). Many  historic battle sites lie along its banks.</p><p>tumour or neoplasm Mass of abnormal tissue that arises from nor�  mal cells, has no useful function, and tends to grow. Cell abnormalities  may include increased size or number or loss of characteristics that dif�  ferentiate their tissue of origin. Cells in malignant tumours (see cancer)  have a distorted size, shape, and/or structure. Less differentiated cells tend  to grow faster. Malignant tumours invade tissues locally and spread  (metastasize) in blood or lymph: the stronger the tendency to metastasize,  the more malignant the tumour. Tumours may not cause pain until they  press on or invade nerves. Both benign and malignant tumours can press  on nearby structures, block vessels, or produce excess hormones, all of  which can cause death. Benign tumours remain as a solid mass that can  be removed by surgery if accessible; they can consist of various tissues  and may become malignant; malignant tumours, though they may remain  quiescent for a time, never become benign.</p><p>tuna Any of seven species (genus Thunnus, family Scombridae) of com�  mercially valuable food fishes. Species range from the 80-lb (36-kg) alba-  core to the bluefin tuna ( T. thynnus), which grows to 14 ft (4.3 m) long  and weighs up to 1,800 lbs (800 kg). Tunas have a slender, streamlined  body and a forked or crescent-shaped tail. They are unique among fishes  in having a vascular system modified to maintain a body temperature  above the water temperature. Though slow swimmers, they migrate long  distances over all the world�s oceans. They eat fishes, squid, shellfish, and  plankton.</p><p>tundra Treeless, level or rolling ground above the taiga in polar regions  (Arctic tundra) or on high mountains (alpine tundra), characterized by  bare ground and rock or by such vegetation as mosses, lichens, small  herbs, and low shrubs. Animal species are limited by harsh environmen�  tal conditions. In the Arctic tundra they include lemmings, the Arctic fox,  the Arctic wolf, caribou, reindeer, and musk-oxen. In the alpine tundra  many animals, including mountain sheep and wildcats, descend to warmer  zones during winter. The climate of alpine tundra is more moderate and  has a higher amount of rainfall than does Arctic tundra. The freezing cli�  mate of the Arctic produces a layer of permanently frozen soil (perma�  frost). An overlying layer of soil alternates between freezing and thawing  with seasonal temperature variations. Alpine tundras have a freeze-thaw  layer but no permafrost. Because Arctic tundras receive extremely long  periods of daylight and darkness (lasting between one and four months),  biological rhythms tend to be adjusted more to variations in temperature  than to variations in sunlight. Arctic tundra covers about one-tenth of the  earth�s surface. Alpine tundras begin above the timberline of spruce and  firs. Because of the small number of plant and animal species and the  fragility of the food chains in tundra regions, natural or mechanical dam�  age to any element of the habitat affects the whole ecosystem.</p><p>tuned circuit Electrically conducting pathway containing both induc�  tance and capacitance elements. When these elements are connected in  series, the circuit presents low electrical impedance to alternating current of  the same frequency as the resonance frequency of the circuit and high  impedance to current of other frequencies. The circuit�s resonance fre�  quency is determined by the values of inductance and capacitance. When  the circuit elements are connected in parallel, the impedance is high at the  resonance frequency and low at other frequencies. With their ability to  pass only certain frequencies, tuned circuits are important in, for example,  radio and television receivers.</p><p>Tung Ch'i-ch'ang See Dong Qichang  Tung Chung-shu See Dong Zhongshu  Tung-lin Academy See Dongun Academy  Tung-Pei See Manchuria  Tung-ting Hu See Dongting Hu</p><p>tungsten or wolfram Vwul-fromX Metallic chemical element, one of  the transition elements, chemical symbol W, atomic number 74.

Its energy is estimated to have  been equivalent to that of about 15 megatons of TNT. Uncertain evidence  suggests that a meteoroid (see meteor) 150-300 ft (45-90 m) in diameter  or, less likely, a comet disintegrated in the atmosphere high above Earth�s  surface, creating a fireball and blast wave but no crater. Eyewitnesses  spoke of a fireball lighting the horizon, initially visible from about 500  mi (800 km) away, followed by trembling ground and hot winds strong  enough to throw people down and shake buildings. The object�s vapor�  ization scattered dust high into the atmosphere, causing abnormally bright  nighttime skies in Siberia and Europe for some time afterward.</p><p>tunicate Vtu-ni-kotV Any of some 2,000 species (chordate subphylum  Tunicata, or Urochordata) of small marine invertebrates that are abundant  worldwide. Tunicates are either sessile (permanently attached), free-  swimming, or planktonic (floating). The name tunicate derives from a  secreted protective covering (the tunic) containing cellulose. Floating spe�  cies often form colonies that may be 13 ft (4 m) long. Some free-  swimming species are too small to see. Adults filter feed on  microorganisms. Sessile forms growing on ships� hulls may be a nuisance,  but some species are pharmaceutically useful. See also sea squirt.</p><p>tuning and temperament In music, the adjustment of one sound  source, such as a voice or string, to produce a desired pitch in relation to  a given pitch, and the modification of that tuning to lessen dissonance.  Tuning assures a good sound for a given pair of tones; temperament com�  promises the tuning to assure a good sound for any and all pairs of tones.  Two vibrating strings sound best together if the ratio between their lengths  can be expressed by two small whole numbers. If two strings vibrate in  a ratio of 2:1, the vibrations will always coincide and so reinforce each  other. But if they vibrate in a ratio of 197:100 (very close to 2:1), they  will cancel each other out three times per second, creating audible �beats.�  These beats are what make something sound �out of tune.� Since a tone  produced by one ratio will not necessarily agree with the same tone cre�  ated by repeatedly applying another ratio, either some intervals must be  mistuned to allow for the perfect tuning of others or all intervals must be  slightly mistuned. Before 1700, several systems were used based on the  former compromise, including �just intonation�; since then, the compro�  mise known as �equal temperament,� in which the ratios represented by  each pair of adjacent notes are identical, has prevailed.</p><p>Tunis Vtu-nosV City (pop., 2004: 728,453), capital of Tunisia. It is situated  on Tunis Lake, an inlet of the Gulf of Tunis; its port, La Goulette (Halq  al-Wadl), is 6 mi (10 km) to the northeast. Founded by Libyans, it was  later a small town under Carthage; it became important after the Muslim  conquest in the 7th century ad. It was a religious centre during the Aghla-  bid dynasty (9th century) and reached its greatest prosperity under the  Hafsid dynasty (13th century). The Spanish and Ottomans controlled it  during the 16th century, and it was occupied by the Germans in 1942. It  was made the national capital when Tunisia gained independence from  France in 1956. It produces textiles, carpets, and olive oil and has met�  allurgical industries. Tourism is also important. The city�s historic centre  was designated a UNESCO World Heritage site in 1979.</p><p>Tunisia \tii-'ne-zh9\ officially Tunisian Republic Country, North  Africa. Area: 63,170 sq mi (163,610 sq km). Population (2005 est.):  10,038,000. Capital: Tunis. The population is of Arab and Berber  (Amazigh) ancestry. Languages: Arabic (official), French. Religion: Islam  (official; predominantly Sunni). Currency: Tunisian dinar. Tunisia com�  prises a coastal region, mountains, an extensive hilly steppe, a marshy  area with shallow salt lakes, and a tract of the Sahara.

From the  12th century bc the Phoenicians had a  series of trading posts on the North African  coast. By the 6th century bc the Carthagin�  ian kingdom encompassed most of present-day Tunisia. The Romans ruled  from 146 bc. It was part of the Byzantine Empire until the Muslim Arab  invasions in the mid-7th century ad. The area was fought over, won, and  lost by many, including the �Abbasid dynasty, the Almohad dynasty, Spain,  and the Ottoman Empire, which conquered it in 1574 and held it until the  late 19th century. For a time it maintained autonomy as the French, Brit�  ish, and Italians contended for the region. In 1881 it became a French  protectorate. During World War II (1939-45) U.S. and British forces cap�  tured it (1943), putting an end to a brief German occupation. France  granted it full independence in 1956; Habib Bourguiba assumed power and  remained in power until he was forced from office in 1987. His succes�  sor, Zine al-Abidine Ben Ali, continued his authoritarian-style rule.</p><p>tunnel Horizontal or nearly horizontal underground or underwater pas�  sageway. Tunnels are used for mining, as passageways for trains and  motor vehicles, for diverting rivers around damsites, for housing under�  ground installations such as power plants, and for conducting water.  Ancient civilizations used tunnels to carry water for irrigation and drink�  ing, and in the 22nd century bc the Babylonians built a tunnel for pedes�  trian traffic under the Euphrates River. The Romans built aqueduct tunnels  through mountains by heating the rock face with fire and rapidly cooling  it with water, causing the rock to crack. The introduction of gunpowder  blasting in the 17th century marked a great advance in solid-rock exca�  vation. For softer soils, excavation is accomplished using devices such as  the tunneling mole, with its rotating wheel that continuously excavates  material and loads it onto a conveyor belt. Railroad transportation in the  19th-20th century led to a tremendous expansion in the number and length  of tunnels. Brick and stone were used for support in early tunnels, but in  modern tunneling steel is generally used until a concrete lining can be  installed. A common method of lining involves spraying shotcrete onto  the tunnel crown immediately after excavation.</p><p>tunneling or barrier penetration In physics, the passage of a par�  ticle through a seemingly impassable energy barrier. Though a particle�s  energy may be too low to surmount a barrier in classical physics, the par�  ticle may still cross the barrier as a consequence of its quantum-  mechanical wave properties. An important application of this  phenomenon is in the operation of the scanning tunneling microscope.</p><p>Tunney, Gene orig. James Joseph Tunney (b. May 25, 1898,  New York, N.Y., U.S.�d.

He retired the next  year with a record of 65 wins in 77 bouts.</p><p>Tupac Amaru Uii-'pak-a-'mar-iA Peruvian revolutionary group.  Founded in 1983, the group is best known for holding 490 people hos�  tage in the Japanese embassy in Lima (1996) in an effort to gain the release  of jailed comrades. After a standoff of several weeks, Peruvian troops  stormed the embassy and killed all the guerrillas. Defections have appar�  ently since decreased its membership. The group takes its name from the  Indian revolutionary Tupac Amaru II (orig. Jose Gabriel Condorcanqui,  17427-81), who in 1780 led Peruvian Indian peasants in the last wide�  spread rebellion against Spain before independence. The Indians identi�  fied him with his ancestor Tupac Amaru, the last leader of the Inca, who  was executed by the Spaniards in 1572.</p><p>Tupamaro V.tii-po-'ma-roN Member of the National Liberation Move�  ment, a Uruguayan leftist urban guerrilla organization founded c. 1963  and named for Tupac Amaru II, an 18th-century Peruvian revolutionary.  The earliest Tupamaro efforts involved robbing banks and businesses and  distributing the goods to the poor, but in the late 1960s they mounted a  wave of violence aimed at the authorities. The military government that  seized power in 1973 launched an offensive against them, killing some  300 and imprisoning 3,000 others. When democratic rule returned in  1985, the Tupamaros were reorganized as a political party.</p><p>tupelo \'tu-p3-,lo\ Any of about seven species of trees that make up the  genus Nyssa in the sour gum family (Nyssaceae). Five are found in moist  or swampy areas of eastern North America, one in eastern Asia, and one  in western Malaysia. They all have horizontal or hanging branches, broad  leaves, and male and female flowers on different plants. North American  species bear greenish-white flowers and small bluish-black or purple ber�  ries. The most widespread North American species is the black gum.  Tupelo wood, most of which comes from the water tupelo ( N. aquatica),  is pale yellow to light brown, fine-textured, and strong.

About one half of the 50 attested Tupian languages are extinct.  The largest subgroup, Tupi-Guaram, includes the extinct language Tupi-  namba, the source for borrowings of many New World flora and fauna  terms into Portuguese and hence other European languages. Another lan�  guage of the subgroup, Guarani, is spoken as a first or second language  by more than 90% of Paraguayans, who consider it a token of Paraguayan  identity.</p><p>Tupolev officially ANTK imeni A.N. Tupoleva formerly OKB-  156 Russian aerospace design bureau that is a major producer of pas�  senger airliners and military bombers. It originated in 1922 as a group  within the U.S.S.R.�s Central Aerohydrodynamics Institute to develop  military aircraft. Under Andrei Tupolev, it created the TB-1 (ANT-4) all-  metal, cantilever-wing bomber (first flights 1925-26). After several years�  confinement for political reasons, Tupolev was freed, and in 1943 he  reestablished his team as the design bureau OKB-156. At the end of World  War II, the bureau built the Tu-4 strategic bomber, a copy of the U.S.  B-29. In the 1950s it produced the turboprop Tu-95 heavy bomber (NATO,  �Bear�), which became a Soviet mainstay, and the first Soviet jetliner, the  Tu-104 (first flown 1955). Between the late 1950s and early �80s, it intro�  duced new supersonic bombers, including the variable-wing Tu-22M  (�Backfire�) and Tu-160 (�Blackjack�), and airliners such as the Tu-114  turboprop, Tu-154 trijet, and Tu-144 supersonic transport. In 1989, in  honor of Tupolev (died 1972), the bureau was renamed ANTK imeni A.N.  Tupoleva. After the dissolution of the U.S.S.R. in 1991, it became a joint  stock company with the Russian government holding a limited financial  interest. In the 1990s its projects involved jetliners such as the Tu-204 (in  service 1996) and Tu-324.</p><p>Tupolev Vtii-pol-yifX, Andrei (Nikolayevich) (b. Nov. 10, 1888,  Pustomazovo, Russia�d. Dec. 23, 1972, Moscow) Russian aircraft  designer. In 1918 he cofounded the U.S.S.R.�s Central Aerohydrodynam�  ics Institute, and in 1922 he became head of its design bureau (see Tupolev),</p><p>producing airplanes of all-metal construction. Arrested in 1937 on charges  of activities against the state, he was assigned to work on the design of  military aircraft. Under confinement, he led a team that produced the Tu-2  twin-engine tactical bomber, which was widely used in World War II.  Freed during the war, Tupolev and his reestablished design bureau rep�  licated the U.S. B-29; the resulting Tu-4 became the Soviet Union�s prin�  cipal strategic bomber until the mid-1950s. After adapting jet propulsion  to several piston-engine airframes, Tupolev introduced the swept-wing  Tu-16 (NATO, �Badger�) jet bomber (first flown 1952) and its civilian  derivative Tu-104 (1955), one of the first jet transports to provide regular  passenger service. Tupolev and his son Alexei headed the effort that pro�  duced the Tu-144 supersonic transport, the first passenger jet to exceed  Mach 1 (1969).</p><p>Turn \'tu-ra\, Cosimo or Cosme Tura (b. c. 1430, Ferrara�d. 1495,  Ferrara) Italian painter. Court painter to the Este family at Ferrara, his early  Renaissance style was influenced by Andrea Mantegna and Piero della  Francesca. A master of allegory and decorative painting, he was the  founder and first significant figure of the school of Ferrara. His work is  characterized by a mannered, nervous, and wiry line, carefully rendered  detail, and brilliant colour.</p><p>TurabI \tu-'ra-be\, Hasan al- (b. 1932, The Sudan) Sudanese Muslim  religious scholar and lawyer. After receiving a traditional Muslim educa�  tion, he studied at the University of London and the Sorbonne in Paris.  In the early 1950s he joined the Sudanese branch of the Muslim Brother�  hood. While teaching law at the University of Khartoum (1957-65), he  participated in the 1958 revolution that ended military rule. He later  served in the national legislature (1965-67). He supported the 1985 over�  throw of Gaafar Mohamed el-NiMEiRi. That same year he formed the  National Islamic Front (NIF), an incarnation of the Muslim Brotherhood.  In 1989 the NIF supported a coup that brought �Umar Hasan al-Bashlr to  power. He later served as speaker of the National Assembly (1996-98)  and was arrested in 2001 during a power struggle with al-Bashlr.</p><p>turbidity current Underwater current of abrasive sediments. Such cur�  rents appear to be relatively short-lived, transient phenomena that occur  at great depths. They are thought to be caused by the slumping of sedi�  ment that has piled up at the top of the continental slope, particularly at  the heads of submarine canyons. Slumping of large masses of sediment  creates a dense slurry, which then flows down the canyon to spread out  over the ocean floor and deposit a layer of sand in deep water. Repeated  deposition forms submarine fans, analogous to the alluvial fans found at  the mouths of river canyons.</p><p>turbine Vtor-bon, 'tor-.blnV Any of various devices that convert the  energy in a stream of fluid into mechanical energy by passing the stream  through a system of fixed and moving fanlike blades and causing the lat�  ter to rotate. A turbine looks like a large wheel with many small radiat�  ing blades around its rim. There are four broad classes of turbine: water  (hydraulic), steam, wind, and gas. The most important application of the  first three is the generation of electricity; gas turbines are most often used  in aircraft.</p><p>turbojet Jet engine in which a TURBiNE-driven compressor draws in and  compresses air, forcing it into a combustion chamber into which fuel is  injected. Ignition causes the gases to expand and to rush first through the  turbine and then through a nozzle at the rear. Forward thrust is generated  as a reaction to the rearward momentum of the exhaust gases. The tur�  bofan or fanjet, a modification of the turbojet, came into common use in  the 1960s. In the turbofan, some of the incoming air is bypassed around  the combustion chamber and is accelerated to the rear by a turbine-  operated fan. It moves a much greater mass of air than the simple turbo�  jet, providing advantages in power and economy. See also ramjet.</p><p>turboprop Hybrid engine that provides jet thrust and also drives a pro�  peller. It is similar to the turbojet except that an added turbine, behind the  combustion chamber, works through a shaft and speed-reducing gears to  turn a propeller at the front of the engine. Because of improvements in  turbojet design, the turboprop, which is less efficient at high speeds, lost  much of its importance in the 1960s, though it is still used for relatively  short-range aircraft.</p><p>turbot Vtor-botN Species (Scophthalmus maximus, family Scophthalmi-  dae or Bothidae) of broad-bodied European flatfish, a highly valued food  fish.

Turbots grow to, at most, 40 in. (1  m) long and weigh about 55 lb (25 kg). Colour varies with the surround�  ings but is usually gray-brown or light brown with darker markings. A  related species is the Black Sea turbot (S. maeoticus). Certain right-sided  Pacific flatfish (genus Pleuronichthys, family Pleuronectidae) are also  called turbot.</p><p>turbulence In fluid mechanics, a flow condition (see turbulent flow) in  which local speed and pressure change unpredictably as an average flow  is maintained. Common examples are wind and water swirling around  obstructions, or fast flow (Reynolds number greater than 2,100) of any sort.  Eddies, vortices, and a reduction in drag are characteristics of turbulence.  Lowered drag enables golf balls to travel farther than they would do oth�  erwise, and the dimpled surface of golf balls is meant to encourage tur�  bulence in the boundary layer. If swimsuits with rough surfaces help  swimmers to move faster, as has been claimed, the same explanation may  apply.</p><p>Turcoman See Turkmen</p><p>Turenne \tu-'ren\, Henri de La Tour d'Auvergne, viscount de  orig.

He earned his reputation  as a military leader in the Thirty  Years' War, especially with the cap�  ture of Turin (1640). Made a marshal  of France (1643), he commanded the  French army in Germany and joined  the Swedish army in conquering  Bavaria (1648). In France he joined  the aristocrats in the Fronde (1649),  but later he skillfully commanded  the royal army to defeat the forces  led by the prince de Conde, who had  allied himself with Spain, and to  bring about the Peace of the Pyrenees  (1659), which ended France�s war  with Spain. Appointed marshal-  general (1660), Turenne marched  alongside Louis XIV in joint com�  mand of the French armies in the War of Devolution (1667-68). His bold  strategies won numerous victories against the imperial army in Germany  (1672-75), but he was killed in action at Sasbach. He was buried with the  kings of France at Saint-Denis and later moved to the Invalides by Napo�  leon, who esteemed Turenne as the greatest military leader in history.</p><p>turf In horticulture, the surface layer of soil with its matted, dense veg�  etation, usually grasses grown for ornamental or recreational use. Such  turf grasses include Kentucky bluegrass, creeping bent grass, fine or red  fescue, and perennial ryegrass among the popular cool-season types, and  Bermuda grass, zoysia grass, and St. Augustine grass among the warm-  season types. Turf grasses are often grown on turf, or sod, farms. Plugs,  blocks, squares, or strips are cut and transplanted to areas where they  quickly establish and grow. Lawns  are fine-textured turfs that are  mowed regularly and closely to  develop into dense, uniformly green  coverings that beautify open spaces  and provide sports playing surfaces  (e.g., tennis lawns, golf and bowling  greens, and racing turfs).</p><p>Turgenev \tur-'g y a-n y if\, Ivan  (Sergeyevich) (b.

He lived in Europe after  c. 1862. He is known for realistic,  affectionate portrayals of the Russian</p><p>peasantry and for penetrating studies of the Russian intelligentsia who  were attempting to move the country into a new age. His most famous  early work is �The Diary of a Superfluous Man� (1850), which supplied  the epithet �superfluous man� for the weak-willed intellectual protagonist  common in 19th-century Russian literature. He gained fame with the  short-story cycle A Sportman�s Sketches (1852), which criticizes serfdom.  His dramatic masterpiece, A Month in the Country (1855), and the novel  Rudin (1856) followed. His interest in change and intergenerational dif�  ferences is reflected in the controversial Fathers and Sons (1862), his  greatest novel. Turgenev�s work is distinguished from that of his contem�  poraries by its sophisticated lack of hyperbole, its balance, and its con�  cern for artistic values. His greatest work was always topical, committed  literature, having universal appeal in the elegance of the love story and  the psychological acuity of the portraiture.</p><p>turgor Vtor-gorV Pressure exerted by fluid in a cell that presses the cell  membrane against the cell wall.

A physiocrat,  in 1766 he wrote his best-known work, Reflections on the Formation and  Distribution of Wealth. In 1774 he was appointed comptroller general by  Louis XVI and introduced his Six Edicts to expand economic reforms. His  effort to abolish the corvee (unpaid forced labour by peasants) was opposed  by the privileged classes, and he was dismissed in 1776.</p><p>Turin Italian Torino City (pop., 2001 prelim.: 857,433), Piedmont  region, northwestern Italy. Located on the Po River, it was founded by the  Taurini. It was partly destroyed by Hannibal in 218 bc. It was made a  Roman military colony under Emperor Augustus. A part of the Lombard  duchy in the 6th century ad, it became the seat of government under  Charlemagne (742-814). It passed to the house of Savoy in 1046. The  capital of the kingdom of Sardinia in 1720, Turin was occupied by the  French during the Napoleonic Wars. The political and intellectual centre  of the Risorgimento movement, it served as the first capital of united Italy  (1861-65). During World War II Turin sustained heavy damage from  Allied air raids but was rebuilt. It is the focus of Italy�s automotive indus�  try and an international fashion centre. The Shroud of Turin has been  housed in the 15th-century cathedral there since the 16th century.</p><p>Turin, Shroud of Linen fragment said to be the burial garment of Jesus.  It has been preserved since 1578 in the royal chapel of the Cathedral of  San Giovanni Battista in Turin, Italy.

The images contain markings that correspond to the  stigmata and stains presumed to be blood. The cloth emerged historically  in 1354 and went on exhibition in 1389, first as a representation of the  shroud and eventually as the shroud itself. In 1988 independent tests using  radiocarbon dating techniques indicated that the cloth had been made c.  1260-1390.

June 7, 1954, Wilmslow, Cheshire) English mathematician and  logician. He studied at the University of Cambridge and at Princeton�s  Institute for Advanced Study. In his seminal 1936 paper �On Computable  Numbers,� he proved that there cannot exist any universal algorithmic  method of determining truth in mathematics and that mathematics will  always contain undecidable (as opposed to unknown) propositions. That  paper also introduced the Turing machine. He believed that computers even�  tually would be capable of thought indistinguishable from that of a human  and proposed a simple test (see Turing test) to assess this capability. He  did valuable work in cryptography during World War II, playing an impor�  tant role in breaking the Enigma code used by Germany for radio com�  munications.

The highest peak is Mount Ararat (16,853 ft  [5,137 m]). The Taurus Mountains lie in the south. Rivers include the Tigris,  Euphrates, Kizil, and Menderes. Turkey is a major producer and exporter of  chromite and also mines iron ore, coal, lignite, bauxite, and copper. It is  the Middle East�s leading steel producer. Chief agricultural products  include wheat, barley, olives, and tobacco. Tourism also is important.  Turkey is a republic with one legislative house; its chief of state is the  president, and the head of government is the prime minister. Turkey�s  early history corresponds to that of Anatolia, the Byzantine Empire, and the  Ottoman Empire. Byzantine rule emerged when Constantine the Great made  Constantinople (modern Istanbul) his capital. The Ottoman Empire, begun  in the 12th century, dominated for more than 600 years; it ended in 1918  after the Young Turk revolt (1908) precipitated its demise. Under the lead�  ership of Mustafa Kemal AtatOrk, a republic was proclaimed in 1923. Tur�  key remained neutral throughout most of World War II (1939-45), siding  with the Allied powers in 1945. Since the war it has alternated between  civil and military governments and has had several conflicts with Greece  over Cyprus. The country has developed a strong, diversified economy,</p><p>but it has also experienced periods of political and civic turmoil between  Islamists and secularists and ongoing ethnic tension with Kurdish sepa�  ratists.</p><p>turkey Either of two species of birds in the family Meleagrididae. The  North American common turkey  (Meleagris gallopavo) has been  domesticated since pre-Columbian  times. The adult male has a feather�  less, bright-red head, a fleshy red  ornament (snood) growing over the  bill, and a similar wattle on the  throat. The male (gobbler or tom)  may be 50 in. (1.3 m) long and may  weigh over 20 lb (10 kg). Wild tur�  keys inhabit woodlands near water,  eating seeds, insects, and an occa�  sional frog or lizard. Males assemble  a harem, and each hen lays 8-15  eggs in a hollow in the ground. An  excellent source of meat and easily  shot, the wild turkey was practically  exterminated by European settlers;  conservation efforts have reestab�  lished it in much of its former range.</p><p>The ocellated turkey {Agriocharis, or Meleagris, ocellata) of Central  America has never been domesticated.</p><p>turkey vulture or turkey buzzard Species ( Cathartes aura) of  long-winged, long-tailed vulture (family Cathartidae), about 30 in. (75 cm)  long, with dark plumage, whitish beak and legs, bare red head covered with  whitish bumps, and a 6-ft (1.8-m) wingspread. It uses its keen sense of  smell to find carrion. It occurs throughout the Americas except in northern  Canada; the northerly and southernmost populations are migratory.</p><p>Turkic languages Family of more than 20 Altaic languages spoken  by some 135 million people from the Balkans to central Siberia. The tra�  ditional division of Turkic is into four groups. The southeastern or Uighur  group comprises Uighur, spoken mainly in Xinjiang, China; and Uzbek,  spoken mainly in Uzbekistan, other Central Asian republics, and north�  ern Afghanistan. The southwestern, or Oguz, group includes Turkish; Azer�  baijani (Azeri), spoken in Azerbaijan and northwestern Iran; Crimean  Tatar, spoken mostly in Ukraine and Uzbekistan; and Turkmen, used in  Turkmenistan, northern Iran, and northern Afghanistan. The northwest�  ern, or Kipchak, group includes Kazakh, spoken in Kazakhstan, other  Central Asian republics, and western China and Mongolia; Kyrgyz, spo�  ken in Kyrgyzstan, other Central Asian republics, and western China;  Tatar; Baskhir, spoken in Bashkortostan and adjacent areas in Russia;  Karachay-Balkar and Kumyk, spoken in the Russian Caucasus; and  Karaim, with a few speakers in Lithuania and parts of southwestern  Ukraine. The northeastern, or Altai, group comprises languages and dia�  lects spoken in Siberia northeast of the Irtysh River and in adjacent parts  of Mongolia, including Altai, Khakas, Shor, and Tuvan; and Sakha, spo�  ken in Sakha (Yakutia) republic of Russia and adjacent areas. Distinct  from all the other languages is Chuvash, spoken in Russia�s Chuvash  republic and adjacent areas. The earliest attestations of Turkic are a group  of 8th-century funerary inscriptions of northern Mongolia, in a distinctive  writing system called runic script, or Turkic runes. With the Islamization  of nearly all Turkic peoples southwest of the Irtysh beginning c. 900,  Turkic languages began to adopt the Arabic alphabet. Today the Latin alpha�  bet and Cyrillic alphabet are more extensively used.</p><p>Turkic peoples Any of various peoples who speak one of the Turkic  languages. They are connected with the Tuque (T�u-chiieh), nomadic  people who in the 6th century ad founded an empire stretching from  Mongolia to the Black Sea (see Turkistan). In the 11th century the SeuOqs  created an extensive empire after defeating the Byzantines at the Battle  of Manzikert (1071), an event that opened Anatolia to settlement by  Turkic-speaking peoples (and eventually led to the establishment of the  Republic of Turkey in the 20th century). Though overrun by the Mongols  in the 13th century, the Turks succeeded in absorbing them after Genghis  Khan�s death (1227). In the 14th century Timur, who was of mixed Mon�  golian and Turkic ancestry, held most of Central Asia and some of South  Asia. In the 15th century Russian expansion drove the Turkic peoples  eastward into what is now Kazakhstan. Today Turkic peoples live mostly  in Turkey, Uzbekistan, Afghanistan, Kazakhstan, and Turkmenistan.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1952 I Turkish Angora cat &#x25BA; turmeric</p><p>Turkish Angora cat Breed of longhaired domestic cat that probably  arose from a domesticated cat of Tatars who migrated to Turkey, where  it is now regarded as a national treasure. It has a long body, fine bones,  a pointed face, and a silky, medium-length coat. White is the most popu�  lar colour, but it may be any of several solid colours or any pattern of two  or more colours.</p><p>Turkish bath Bath originating in the Middle East, combining exposure  to warm air, steam immersion, massage, and a cold bath or shower. The  Turkish bath ( hammam ) reflects the fusion of the massage and cosmetic  aspects of the Eastern bath tradition and the plumbing and heating tech�  niques of the Romans. Turkish baths were smaller than the Roman ther�  mae and more sparsely lit. The baths at Constantinople were domed, and  rooms were richly decorated with marble or mosaics. Used for socializ�  ing and relaxation as well as bathing, the hammam was popular through�  out the Islamic world; some baths are still in use. In the 19th century, the  Turkish bath was adapted and exported to Europe and the U.S.</p><p>Turkish language Turkic language of Turkey, spoken by about 90%  of its population. Turkish has about 59 million speakers, with many  enclaves in the Balkans and Cyprus (dating from Ottoman times) and in  western Europe. Turkish was introduced into Anatolia with the invasion  of Turkmen tribes in the 13th�14th centuries. Anatolian Turkish, written  in the Arabic alphabet, is first attested in the 13th century. Ottoman Turk�  ish was so heavily influenced by Persian and Arabic that it lost some of  its Turkic characteristics and was incomprehensible to lower social strata.  Efforts to re-Turkicize the language began in the 18th century but did not  make serious gains until the 20th century and the founding of the Turk�  ish republic. Much Perso-Arabic vocabulary was removed, and the Latin  alphabet was adopted with the addition of diacritics to symbolize sounds  peculiar to Turkish.</p><p>Turkish van cat Breed of semi-longhaired domestic cat distinguished  mainly by its unusual colour pattern: white, with coloured markings only  on the head and tail. �Van� is a common term in the breed�s native region,  Central and South Asia, used also to describe other cats with similar  markings. The breed was brought to Europe by returning Crusaders. A  unique feature is its cashmere-like, waterproof coat; it loves water, and  in its native region it has been called the swimming cat. It is large, active,  and intelligent.</p><p>Turkistan or Turkestan Historical region, Central Asia. This some�  what broad geographic region�situated between Siberia to the north and  Tibet, India, Afghanistan, and Iran to the south�derived its name from  its inhabitants, who were predominantly of Turkic ancestry. The total area  of more than 1,000,000 sq mi (2,600,000 sq km) was bisected by the Pamir  and Tien Shan ranges, forming West and East Turkistan. West Turkistan,  which included what is now Turkmenistan, Uzbekistan, Tajikistan, Kyr�  gyzstan and southern Kazakhstan, came under Russian rule in the 19th  century. East Turkistan was annexed by China in the 8th century; it  included what is now the Uygur Autonomous Region of Xinjiang.</p><p>Turkmen Member of a Central Asian people belonging to the south�  western branch of the Turkic linguistic group. At the beginning of the 21st  century, they numbered more than six million, and most lived in Turk�  menistan and adjacent parts of Central Asia. A significant number also  live in Iran and parts of Turkey and Afghanistan, and there are pockets  of Turkmen in northern Iraq and Syria. Initially a nomadic pastoral people  living in tent villages, many took up agriculture while under Soviet rule.  Most are Muslim, and they have traditionally divided themselves by eco�  nomic function. They are patrilineal, and each family or tribal group is  headed by a khan.</p><p>Turkmenistan Country, Central Asia. Area: 188,500 sq mi (488,100 sq  km). Population (2005 est.): 4,833,000. Capital: Ashgabat. Turkmen make  up three-fourths of the population, with small groups of Uzbeks, Russians,  Kazakhs, and Tatars. Language: Turkmen (official). Religions: Islam (pre�  dominantly Sunni); also Eastern Orthodox. Currency: manat. There are  some hills and low mountains. About nine-tenths of Turkmenistan is  desert, chiefly the Karakum. The main rivers are the Amu Darya and  Morghab. Many irrigation canals and reservoirs have been built, includ�  ing the Karakum Canal, which runs 870 mi (1,400 km) between the Amu  Darya and the Caspian Sea. The country�s chief products are petroleum  and natural gas, cotton, silk, carpets, fish, and fruit. It is a republic with  one legislative house; its head of state and government is the president,  assisted by the People�s Council. The earliest traces of human settlement  in Central Asia, dating to Paleolithic times, have been found in Turkmen�</p><p>istan. The nomadic, tribal Turkmen prob�  ably entered the area in the 11th century  ad. They were conquered by the Russians  in the early 1880s, and the region became  part of Russian Turkistan. It was organized  as the Turkmen S.S.R. in 1924 and became a constituent republic of the  U.S.S.R. in 1925. The country gained full independence from the Soviet  Union in 1991 under the name Turkmenistan. It experienced years of eco�  nomic difficulty until oil and gas production was more fully developed  and was subject to the highly authoritarian rule of Saparmurad Niyazov.</p><p>Turks and Caicos \'ka-,kos, 'ka-kosX Islands British dependency  (pop., 2002 est.: 18,738), West Indies. It comprises two small island groups  at the southeastern end of The Bahamas. The Turks group includes Grand  Turk, Salt Cay, and lesser cays. The Caicos group includes South Caicos,  East Caicos, Middle (or Grand) Caicos, North Caicos, Providenciales,  West Caicos, and several smaller cays. The seat of government is at Cock-  bum Town on Grand Turk Island. When Spanish explorer Juan Ponce de  Leon visited in 1512, the islands were inhabited by Indians. British colo�  nists from Bermuda arrived in 1678. The islands were at first placed under  the government of The Bahamas, but in 1874 they were annexed to the  colony of Jamaica. The Turks and Caicos Islands became a crown colony  in 1962 and shared a governor with  The Bahamas from 1965 to 1973. A  new constitution was adopted in  1988. The chief industries are tour�  ism and offshore financial services.</p><p>turmeric Vtar-ms-rikX Perennial  herbaceous plant (Curcuma longa;  family Zingiberaceae), native to  southern India and Indonesia. Its  tuberous rhizomes have been used  from antiquity as a condiment, as a  textile dye, and medically as an aro�  matic stimulant. The rhizome has a  pepperlike aroma and a somewhat  bitter, warm taste. It colours and fla�  vours prepared mustard and is used  in curry powder, relishes, pickles,  spiced butters, and numerous culi�  nary dishes. Paper tinged with tur�  meric turns from yellow to reddish  brown when an alkali is added to it,  thus providing a test for alkalinity.</p><p>Turmeric (Curcuma longa).</p><p>W.H.

March 14, 1932, San Marino, Calif.) U.S. historian. He taught  at the University of Wisconsin and at Harvard University. Deeply influ�  enced by his Wisconsin childhood, Turner rejected the doctrine that U.S.  institutions could be traced mainly to European origins, and he demon�  strated his theories in a series of essays. In �The Significance of the Fron�  tier in American History� (1893) he asserted that the American character  had been shaped by frontier life and the end of the frontier era. Later he  focused on sectionalism as a force in U.S. development. His essays were  collected in The Frontier in American History (1920) and Significance of  Sections in American History (1932, Pulitzer Prize).</p><p>Turner, J(oseph) M(allord) W(illiam) (b. April 23, 1775, London,  Eng.�d. Dec. 19, 1851, London)</p><p>British landscape painter. The son of  a barber, he entered the Royal Acad�  emy school in 1789. In 1802 he  became a full academician and in  1807 was appointed professor of per�  spective. His early work was con�  cerned with accurate depictions of  places, but he soon learned from  Richard Wilson to take a more poetic  and imaginative approach. The Ship�  wreck (1805) shows his new empha�  sis on luminosity, atmosphere, and  Romantic, dramatic subjects. After a  trip to Italy in 1819, his colour  became purer and more prismatic,  with a general heightening of key. In  later paintings, such as Sunrise, with  a Boat Between Headlands (1845),  architectural and natural details are  sacrificed to effects of colour and  light, with only the barest indication  of mass. His compositions became more fluid, suggesting movement and  space. In breaking down conventional formulas of representation, he  anticipated French Impressionism. His immense reputation in the 19th cen�  tury was due largely to John Ruskin�s enthusiasm for his early works;  20th-century critics celebrated the abstract qualities of his late colour  compositions.</p><p>Turner, Nat (b. Oct. 2, 1800, Southampton county, Va., U.S.�d. Nov.  11, 1831, Jerusalem, Va.) U.S. insurrectionist. Born into slavery, he  became convinced of his mission to lead American slaves out of bond�  age and developed a scheme to capture the armoury at Jerusalem, Va. He  took an eclipse of the sun as a sign to act (1831) and began his insurrec�  tion by killing his master�s family. He led 75 slaves as they killed about  60 whites on a two-day march to Jerusalem. About 3,000 state militia and  local whites defeated the insurrectionists, who were captured or killed.  Turner eluded arrest for six weeks but was found, tried, and hanged.  Alarmed by the uprising. Southern states passed legislation forbidding the  education, movement, or assembly of slaves.</p><p>Turner, Ted orig. Robert Edward Turner, III (b. Nov. 19, 1938,  Cincinnati, Ohio, U.S.) U.S. broadcasting entrepreneur. He took over his  father�s Atlanta-based advertising firm after the latter�s 1963 suicide and  restored it to profitability. In 1970 he bought the Atlanta television sta�  tion WJRJ (later WTBS), which in 1975 became the superstation of the  Turner Broadcasting System, broadcasting via satellite to cable systems  nationwide. An avid sportsman, he purchased professional baseball and  basketball franchises in Atlanta, and in 1977 he piloted his yacht. Cou�  rageous, to victory in the America's Cup race. He expanded his broadcast�  ing empire with the 1980 launch of the Cable News Network (CNN) and  the 1986 purchase of MGM/UA Entertainment (MGM) and its library of  more than 4,000 movies. He married Jane Fonda in 1991 (divorced 2001).  In 1996 he merged his broadcasting system with Time Warner and became  its vice-chairman (see AOL Time Warner). In 2003 he resigned as vice-  chairman of AOL Time Warner.</p><p>Turner syndrome Chromosomal disorder (from the presence of only  one sex chromosome, X, in all or some of the body�s cells) that causes  abnormal sexual development in females. The syndrome may include  absent or undeveloped ovaries, underdeveloped secondary sex character�  istics, low hairline, webbed neck, shield-shaped chest with wide-spaced  nipples, and kidney and heart malformations with coarctation (narrow�</p><p>ing) of the aorta. It may not be recognized until a girl fails to undergo  puberty at a normal age. Estrogen treatment results in puberty, adult  appearance, and normal sex drive but not fertility. Surgery can correct  malformations.</p><p>turnip Hardy biennial plant in the mustard family, cultivated for its fleshy  roots and tender leaves. There are two species, the turnip proper (Bras-  sica rapa) and the Swedish turnip, or RUTABAGA. The true turnip probably  originated in middle and eastern Asia and spread by cultivation through�  out the temperate zone. Both species are cool-season crops. Turnips  develop rapidly enough to have an early-spring or late-summer seeding  produce a crop before, respectively, extremes of summer or late-fall  weather occur.</p><p>turpentine Any resinous exudate or extract from conifers, especially  pines; now also commonly a term for its volatile fraction, oil (or spirits)  of turpentine. Semifluid mixtures of organic compounds consisting of res�  ins dissolved in a volatile oil, turpentines can be distilled (see distillation)  into the volatile oil of turpentine and the nonvolatile rosin. The oil, a mix�  ture of monoterpenes (see isoprenoid), chiefly pinene, is a colourless, odor�  ous, flammable liquid that does not mix with water but is a good solvent  for many substances. Oil of turpentine is favoured over petroleum solvents  as an oil-paint thinner, varnish solvent, and brush cleaner. Its chief use is  now as a raw material for resins, insecticides, oil additives, and synthetic  pine oil and camphor and as a solvent.</p><p>turquoise Hydrated copper and aluminum phosphate mineral,  CuA 1 6 (P0 4 ) 4 (OH) 8 4H 2 0, that is used extensively as a gemstone. The  colour of turquoise ranges from blue through various shades of green to  greenish and yellowish gray. A delicate sky-blue, which provides an  attractive contrast with precious metals, is most valued for gem purposes.  Numerous deposits of turquoise in the southwestern U.S. have been  worked for centuries by American Indians. The mineral also occurs in  Iran, northern Africa, Australia, and Siberia.</p><p>turtle Any of more than 250 species (order Chelonia) of reptiles having  a bony shell overlaid with horny shields; found in most parts of the world.  Turtles have existed for 200 million years, making them the oldest of all  surviving reptiles. Most species are aquatic or semiaquatic; some are ter�  restrial. Turtles eat plants, animals, or both. They are toothless, have a  horny beak, and range from less than 4 in. (10 cm) to more than 7 ft (2  m) long. They have sturdy, sprawling limbs with short feet or paddlelike  flippers (marine turtles). Some species bend the neck sideways, but most  pull the head and neck backward into the shell. Almost half the known  turtle species are rare, threatened, or endangered. See also box turtle,  PAINTED TURTLE, SNAPPING TURTLE, SOFTSHELL TURTLE, TERRAPIN, TORTOISE.</p><p>turtledove Species ( Streptopelia turtur, family Columbidae) of migra�  tory European pigeon that winters in northern Africa. It is about 11 in. (28  cm) long and has a reddish brown body, blue-gray head, and white-tipped  tail. A ground feeder, it eats prodigious amounts of small seeds. The name  is applied to other temperate and tropical Old World Streptopelia species  of slim, fast-flying game birds. The ringed turtledove, or ringdove, has  feral populations in California and Florida, U.S.; the laughing and spot�  ted doves have also been introduced outside their native habitats.</p><p>Tuscany Italian Toscana Region (pop., 2001 prelim.: 3,460,835),  west-central Italy. It covers 8,877 sq mi (22,992 sq km), and its capital is  Florence. Originally settled by Etruscans c. 1000 bc, Tuscany came under  Roman rule in the 3rd century bc. It was a Lombard duchy in the 6th  century ad. It comprised several independent city-states in the 12th� 1 3th  centuries, which were subsequently united under the Medici family of Flo�  rence. Tuscany passed to the house of Lorraine in 1737 and to Sardinia  and the Kingdom of Italy in the 1860s. The region suffered severe dam�  age in World War II and extensive floods in 1966. Its mineral resources  include the world-famous Carrara marble. Its agricultural products include  olives, olive oil, wines, and livestock. Tourism is important at its histori�  cal centres, including Florence and Pisa.</p><p>Tusculum Vtos-kyo-bmV Ancient town, Latium, Italy. Located near Rome,  it was a Latin settlement as early as the 1st millennium bc and probably  was under the influence of the Etruscans. It was a favourite resort of  wealthy Romans (1st century Bc^lth century ad), and it was the home of  orator Marcus Tullius Cicero. Tourist attractions include a Roman forum, a  2nd-century amphitheatre, and a medieval castle.</p><p>Tuskegee Airmen \t3-�ske-ge\ Black servicemen of the U.S. Army Air  Forces (USAAF) who trained at Alabama�s Tuskegee Army Air Field in</p><p>Detail of a self-portrait by J.M.W.

They constituted the first African American flying unit in  the U.S. military. The first class trained at Tuskegee in 1941 became the  99th Pursuit Squadron, commanded by Lt. Col. Benjamin O. Davis, Jr..  They flew their first mission in the Mediterranean in 1943. Later that year  the army activated three more squadrons; joined with the 99th in 1944,  they constituted the 332nd Fighter Group. The latter was the USAAF�s  only escort group that did not lose a bomber to enemy planes. A second  black flying group, the 477th Bombardment Group, was established near  the end of the war. In all, the Tuskegee Airmen flew 1,578 missions,  destroyed 261 enemy aircraft, and won over 850 medals.</p><p>Tuskegee University Private university in Tuskegee, Alabama, U.S.  Booker T. Washington founded the school in 1881 as a teachers� college  for blacks, and it still has a predominantly African American student body.  George Washington Carver conducted most of his research (1896-1943)  at Tuskegee, and Frederick D. Patterson, founder of the United Negro  College Fund (1944), served as the school�s president (1935-53). The  infamous Tuskegee syphilis study, a U.S. Public Health Service project  examining the course of untreated syphilis in black men, was based there  from the 1930s. Today the university comprises schools of arts and sci�  ences, agriculture, business, education, engineering and architecture, nurs�  ing, and veterinary medicine.</p><p>Tussaud \tu-'so\, Marie orig.

From  1780 until the French Revolution, she served as art tutor to Louis XVI�s  sister. During the Reign of Terror she made death masks from heads�  frequently those of her friends�freshly severed by the guillotine. In 1802  she moved to Britain with her collection of wax models. Her museum  contains a variety of historical figures, including the original models she  made of her great contemporaries, including Voltaire and Benjamin Fran�  klin. By the turn of the 21st century, branches of her museum were located  throughout the world.</p><p>tussock moth Typical member of the small European and New World  lepidopteran family Liparidae (formerly Lymantriidae). The large, hairy  larvae of most species have hair tufts, or tussocks; many have stinging  hairs. Several species, including the gypsy moth, browntail moth, satin  moth, and nun moth, damage trees. The larvae feed on foliage, sometimes  foraging from a silken tent or a colonial nest of webbed leaves. Larvae  pupate in a cocoon attached to a tree branch or trunk. Adult females range  from white to brown; some, such as the white-marked tussock moth, are  wingless. See also moth.</p><p>Tutankhamen X.tu-.taq-'ka-monV orig.

They speak Rundi or Rwanda (mutually intelligible lan�  guages of the Niger-Congo family) and number some 1.5 million. The  Tutsi represent a traditional aristocratic minority, which has dominated  the more populous Hutu. Originally warrior-herders, the Tutsi entered the</p><p>area in the 14th or 15th century and later, assisted by German and Bel�  gian colonial regimes, cultivated a lord-vassal relationship with the Hutu.  At the head of the pyramidal political structure was the mwami (�king�),  considered to be of divine origin. Today Hutu and Tutsi cultures have  largely become integrated. In addition to sharing languages, they both  adhere to similar traditional and/or Christian religious beliefs. The Tutsi  retained their dominant position over the Hutu in Rwanda until 1961,  when the monarch was overthrown. An unsuccessful Hutu revolt in  Burundi in 1972 led to 100,000 deaths, mostly Hutu. In 1993 in Burundi  and in 1994 in Rwanda, further clashes occurred, the latter including a  genocidal campaign by Hutu militia and civilians in which more than a  million Tutsi and their Hutu allies were killed and one to two million Hutu  fled to refugee camps in Congo (Kinshasa; then Zaire) and Tanzania.</p><p>Tutu, Sir Desmond (Mpilo) (b.

In 1978 he became general secretary  of the South African Council of Churches and an eloquent and outspoken  advocate for the rights of black South Africans. He emphasized nonviolent  protest and encouraged other countries to apply economic pressure to  South Africa. In 1984 he received the Nobel Prize for Peace for his role in  opposing apartheid. In 1986 he was elected the first black archbishop of  Cape Town and titular head of South Africa�s 1.6-million-member Angli�  can Church. He retired from the primacy in 1996 and became chairman of  the Truth and Reconciliation Commission, charged with hearing evidence  of human-rights violations under white rule.

Area:  9.9 sq mi (25.6 sq km). Population (2005 est.): 9,700. Capital: Vaiaku, Fon-  gafale islet (of Funafuti atoll). The majority of the people are Polynesian.  Languages: Tuvaluan; English is widely used. Religion: Christianity (pre�  dominantly Protestant). Currency: Tuvalu dollar (equivalent to the Austra�  lian dollar). Tuvalu is an island group comprising five atolls and four coral  islands, all of them low-lying, with maximum elevations below 20 ft (6 m),  and covered mainly with coconut palms, breadfruit trees, and grasses. The  economy is based on subsistence agriculture and livestock raising. Tuvalu  is a constitutional monarchy with one legislative house; its chief of state is  the British monarch represented by the governor-general, and the head of  government is the prime minister. The original Polynesian settlers probably  came mainly from Samoa or Tonga. The islands were sighted by the Span�  ish in the 16th century. Europeans settled there in the 19th century and  intermarried with Tuvaluans. During this period Peruvian slave traders  known as �blackbirders� decimated the population. In 1856 the U.S.  claimed the four southern islands for guano mining. Missionaries from  Europe arrived in 1865 and rapidly converted the islanders to Christianity.  In 1892 Tuvalu, then known as the Ellice Islands, joined the British Gilbert  Islands, a protectorate that became the Gilbert and Ellice Islands colony in  1916. Tuvaluans voted in 1974 for separation from the Gilberts (now Kir�  ibati), whose people are MlCRONESlAn. Tuvalu gained independence in 1978,  and in 1979 the U.S. relinquished its claims.

At age 13 he was apprenticed to a local printer. In 1856  he signed on as an apprentice to a steamboat pilot. He plied the Missis�  sippi for almost four years before going to Nevada and California. In 1863  he took his pseudonym, the riverman�s term for water �two fathoms  deep.� In a California mining camp he heard the story that he would make  famous as �The Celebrated Jumping Frog of Calaveras County� (1865).  He traveled widely, using his travels as subject matter for lectures and  books, including the humorous narratives The Innocents Abroad (1869)  and Roughing It (1872). He won a worldwide audience for his stories of  youthful adventures, especially Tom Sawyer (1876), The Prince and the  Pauper (1881), Life on the Mississippi (1883), and Huckleberry Finn  (1884), one of the masterpieces of American fiction. The satirical A Con�  necticut Yankee in King Arthur�s Court (1889) and increasingly grim  works including Pudd�nhead Wilson (1894) and The Man Who Corrupted  Hadleyburg (1900) followed. In the 1890s financial speculations bank�  rupted him, and his eldest daughter died. After his wife�s death (1904),  he expressed his pessimism about human character in such late works as  the posthumously published Letters from the Earth (1962).</p><p>tweed Medium- to heavy-weight fabric, rough in surface texture, pro�  duced in a great variety of colour and weave effects (see weaving).

As city aider-  man (1851-56), he gained influence  in Tammany Hall and obtained impor�  tant positions in city government. He  appointed political cronies to key  city posts and built a group later  called the Tweed ring. As head of  Tammany�s general committee  (from 1860), he controlled the  Democratic Party�s nominations to  all city positions. He opened a law  office to receive payments for �legal  services� from city contractors and  corporations. Elected to the state  senate (1868), he also became Tam�  many�s grand sachem (leader) and  controlled city and state political  patronage. He gained control of the city treasury and plundered sums esti�  mated at between $30 million and $200 million. Reformers and exposure  by the press, including Thomas Nast�s cartoons in Harper�s Weekly,  brought prosecution, led by Samuel Tilden, that resulted in Tweed�s con�  viction and imprisonment (1873-75, 1876-78).</p><p>Boss Tweed</p><p>COURTESY OF THE LIBRARY OF CONGRESS, WASHINGTON,</p><p>Twelve Tables, Law of the Earliest codification of ancient Roman  law, traditionally dated to 451-450 bc.

The  Twelve Tables were not a reform or a liberalizing of old custom; they  recognized the prerogatives of the patrician class and of the patriarchal  family, the validity of enslavement for unpaid debt, and the interference  of religious custom in civil cases. Because only random quotations from  the Twelve Tables are extant, knowledge about their contents is largely  derived from references in later juridical writings.

In regu�  lar twill, the diagonal line is repeated regularly, usually running upward  from left to right at 45�. The weave can be varied in many ways�for  example, by changing the direction of the twill line (as in herringbone  twill) or its angle. Twill is much used for men�s wear and many other  clothing applications because it has stretch on both diagonals, which  makes clothes comfortable even if closely fitted.

The region  was conquered by the Normans in the 11th century; the two areas were  divided in 1282 between the Angevin (French) dynasty on the mainland  and the Aragonese (Spanish) dynasty on the island, both of which claimed  the title of King of Sicily. In 1442 Alfonso V of Aragon reunited the two  areas and took the title of King of the Two Sicilies. This title was sometimes  used during the Spanish and Bourbon rule of the region in the 16th-19th  centuries; it became official in 1816, when the administration of both areas  was combined and Sicily lost its autonomy.

In the U.S. House of Rep�  resentatives (1817-21) and Senate (1827-36), he was a supporter of states'  rights. Though a slaveholder, he sought to prohibit the slave trade in the  District of Columbia, provided Maryland and Virginia concurred. He  resigned from the Senate rather than acquiesce to state instructions to  change his vote on a censure of Pres. Andrew Jackson. After breaking with  the Democratic Party, he was nominated by the Whig Party for vice presi�  dent under William H. Harrison. They won the 1840 election, carefully  avoiding the issues and stressing party loyalty and the slogan �Tippecanoe  and Tyler too!� Harrison died a month after taking office, and Tyler became  the first to attain the presidency �by accident.� He vetoed a national bank  bill supported by the Whigs, and all but one member of the cabinet  resigned, leaving him without party support. Nonetheless, he reorganized  the navy, settled the second of the Seminole Wars in Florida, and oversaw  the annexation of Texas. He was nominated for reelection but withdrew in  favour of James K. Polk and retired to his Virginia plantation. Committed to  states� rights but opposed to secession, he organized the Washington Peace  Conference (1861) to resolve sectional differences.

He  taught at Oxford University (1884�</p><p>1909), where he became the first pro�  fessor of anthropology. His Primitive  Culture, 2 vol. (1871), influenced by  Charles Darwin, developed the theory  of an evolutionary relationship  between what he called primitive and  modern cultures, stressing the cul�  tural achievements that marked the  progression of all humanity from a  �savage� to a �civilized� state. At a  time when there was still controversy  over whether all human races  belonged to a single species, Tylor  was a powerful advocate of the unity  of all humankind.

By not allowing propositional functions to be applied to arguments  of equal or higher type, contradictions within the system are avoided.</p><p>typesetting Setting of type for use in any of various printing processes.  Type for printing, using woodblocks, was invented in China in the 11th  century, and movable type using metal molds had appeared in Korea by  the 13th century. It was reinvented in Europe in the 1450s by Johannes  Gutenberg. For much of its history, typesetting and printing were often  performed by the same person, who arranged movable type, one charac�  ter at a time, in rows corresponding to the individual lines in the publi�  cation and operated the hand press to imprint the image on paper.  Typesetting was revolutionized in the 1880s with the invention of the  �hot-metal� processes: Linotype (1884), in which the lines of type were  assembled by use of a typewriter-like keyboard and each line was cast as  a single slug of molten metal, and Monotype (1887), which also used a  keyboard but cast each character separately. Photocomposition�the com�  position of text directly on film or photosensitive paper using a rotating  drum or disk with cutout type characters through which light could be  directed onto the receiving surface�appeared in the early 20th century.  By the late 20th century, computers and publishing software generated  characters and handled most hyphenation, layout, and other page-makeup  decisions, with the resulting electronic file, including any graphics, passed  to a laser printer for paper or film reproduction.</p><p>typewriter Machine for writing characters similar to those made by  printers� types, especially a machine in which the characters are produced  by steel types striking the paper through an inked ribbon, the types being  activated by corresponding keys on a keyboard and the paper being held  by a roller (the platen) that is automatically moved along with a carriage  when a key is struck. The first practical typewriter was patented in 1868  by Christopher L. Sholes; commercial production began at the Remington  firearms company in 1874. By the end of the century the typewriter had  come to dominate the American office. The first electric typewriter for  office use was introduced in 1920. From the 1970s typewriters began to  be replaced by personal computers and their associated printers.</p><p>typhoid or typhoid fever Acute infectious disease resembling typhus  (and distinguished from it only in the 19th century). Salmonella typhi,  usually ingested in food or water, multiplies in the intestinal wall and then  enters the bloodstream, causing septicemia. Symptoms begin with head�  ache, aching, and restlessness. High fever gradually develops, with  delirium. A rash appears on the trunk. The sites where the bacilli multi�  plied become inflamed and may ulcerate, leading to intestinal bleeding or  peritonitis. Patients become exhausted and emaciated; up to 25% die if not  treated. Antibiotic treatment is effective. Patients can carry typhoid for  weeks to months or years. Carriers can contaminate the food they handle.  Prevention depends mainly on water and sewage treatment and exclud�  ing carriers from food-handling jobs.</p><p>Typhoid Mary byname o/ Mary Mallon (b. 1870?�d.

She fled, but authorities finally caught up with her  and isolated her on an island off the Bronx. In 1910 she was released after  agreeing not to take a food-handling job, but she did, causing more  typhoid outbreaks. She was returned to the island for the rest of her life.  Three deaths and 51 original cases were directly attributed to her.</p><p>Typhon In Greek mythology, the youngest son of Gaea and Tartarus.

Typography  originated after the invention of printing from movable type in the mid  15th century. The three major type families in the history of Western  printing are roman, italic, and black letter (Gothic). All had their origin in  the scripts of the calligraphers whose work was ultimately replaced by  printing. In the succeeding centuries typographers have created some  10,000 typefaces (a complete set of letter forms of a particular design).  Depending on the style of their letters, typefaces are categorized as old  style, transitional, and modem. Commonly used typefaces include Caslon,  Baskerville, Bodoni, Garamond, and Times New Roman. See also John  Baskerville; Giambattista Bodoni; Stanley Morison. The selection of a type�  face is an important part of the aesthetic process in graphic design.</p><p>tyrannosaur Any of a group of related carnivorous dinosaurs similar  to the allosaurs. Tyrannosaurus rex is the largest and best known, found  as fossils in Late Cretaceous (99-65 million years ago) deposits of North  America and eastern Asia. Some adults were more than 40 ft (12 m) long  and 16-18 ft (over 5 m) tall and weighed 6 tons (5.4 metric tons) or more.  Tyrannosaurs walked with a stooped posture, carrying the body forward  and the long tail off the ground. They had a short, thick neck, a very large  skull, and pointed teeth, up to 6 in. (15 cm) long, with serrated edges.  Each small forelimb had two claws, perhaps for holding struggling prey.  A nearly complete skeleton of T. rex called �Sue� is on display at the  Field Museum in Chicago. Other tyrannosaurs include Albertosaurus,  Alectrosaurus, and Nanotyrannus.</p><p>tyrant In ancient Greece, a cruel and oppressive absolute ruler. The Greek  tyrannos was a ruler who seized power unconstitutionally or inherited such  power.

Probably founded as a colony of Sidon, it was first mentioned in the 14th  century bc; it is frequently mentioned in the Bible. Tyre successfully  resisted a 6th-century-Bc siege of 13 years by the Babylonian king Neb�  uchadrezzar II, but it fell to Alexander the Great in 332 bc. Ruled later by  the Seleucid dynasty and then by the Romans, it passed to the Muslims in  the 7th century ad. After its capture by the Crusaders in 1124, it became  a chief city of the kingdom of Jerusalem (see Crusades). It fell again to  the Muslims in 1291 and was destroyed. The modern city was included  in Lebanon in 1920 and was occupied by Israeli forces (1982-85). Its main  economic activity is fishing.

Though  apprenticed to the sculptor Lorenzo Ghiberti, he is not known to have  worked in sculpture, and at 18 he was admitted to the painters� guild in  Florence. The Deluge , one of his frescoes in the Chiostro Verde of Santa  Maria Novella, demonstrates his intense study of perspective. He became  so firmly identified with perspective that John Ruskin thought he had  invented it. His three panels depicting the Battle of San Romano, like all  the extant works of his mature years, combine the decorative late Gothic  style with the new heroic style of the early Renaissance.</p><p>UCLA See University of California</p><p>�Gd \iid\ Stringed instrument prominent in medieval and modem Islamic  music, forerunner of the European lute.

Uganda is a republic  with one legislative house; its head of state and government is the presi�  dent. By the 19th century the region was divided into several separate local  kingdoms inhabited by various Bantu- and Nilotic-speaking peoples. Arab  traders reached the area in the 1840s. The kingdom of Buganda was visited  by the first European explorers in 1862. Protestant and Catholic mission�  aries arrived in the 1870s, and the development of religious factions led to  persecution and civil strife. In 1894 Buganda was formally proclaimed a  British protectorate. As Uganda, it gained independence in 1962, and in  1967 it adopted a republican constitution. The civilian government was  overthrown in 1971 and replaced by a military regime under Idi Amin. His  invasion of Tanzania in 1978 resulted in the collapse of his regime. The  civilian government was again deposed by the military in 1985, but the  military government was in turn overthrown in 1986.

Screen paintings were  the first works to be done in the style, which depicted aspects of the enter�  tainment quarters (�floating world�) of Edo (modem Tokyo) and other  cities. Ukiyo-e artists switched their focus to wood-block prints, which  were mass-produced for an eager public. Favourite ukiyo-e subjects  included famous courtesans and prostitutes, kabuki actors in famous roles,  and erotica; they were executed in flat, decorative colours and expressive  patterns. Hishikawa Moronobu is generally accredited as the first master  of ukiyo-e. The transition from single- to two-colour prints was made by  Okumura Masanobu; in 1765 polychrome prints using numerous blocks  were introduced by Suzuki Harunobu. The essence of the ukiyo-e style  was embodied in the works of Utamaro, Hokusai, and Hiroshige. The prints  attracted much attention in Europe in the 19th century and had a great  influence on avant-garde French artists such as the Impressionists and Post-  Impressionists.</p><p>Ukraine \yu-'kran\ Country, eastern Europe. Area: 233,062 sq mi  (603,628 sq km). Population (2005 est.): 47,075,000. Capital: Kiev. Ukrai�  nians make up more than three-fourths of the population; there is a sig�</p><p>nificant minority of Russians. Languages:  Ukrainian (official), Russian, Romanian,  Polish, Hungarian. Religions: Christianity  (mostly Eastern Orthodox; also other  Christians, Roman Catholic, Protestant),  Islam. Currency: hryvnya. Ukraine consists of level plains and the Car�  pathian Mountains, which extend through the western region for more than  150 mi (240 km). The Bug (Western Bug), Dnieper (Dnipro), Donets, and  Dniester (Dnistro) are the major rivers. The Donets Basin in the east-central  region is one of the major heavy-industrial and mining-metallurgical com�  plexes of Europe. There iron ore and coal are mined, and natural gas,  petroleum, iron, and steel are produced. Ukraine is a major producer of  winter wheat and sugar beets. It is a republic with one legislative body;  its head of state is the president, and the head of government is the prime  minister. Different parts of the area were invaded and occupied in the 1st  millennium bc by the Cimmerians, Scythians, and Sarmatians and in the  1st millennium ad by the Goths, Huns, Bulgars, Avars, Khazars, and  Magyars. Slavic tribes settled there after the 4th century. Kiev was the  chief town. The Mongol conquest in the mid-13th century decisively  ended Kievan power. Ruled by Lithuania in the 14th century and Poland  in the 16th, the area fell to Russian rule in the 18th century. After the  Russian Revolution of February 1917, Ukrainian and Bolshevik forces  struggled for control of Ukraine until 1921, when the Bolsheviks pre�  vailed. In 1924 the Ukrainian S.S.R. became a republic of the Soviet  Union. The northwestern region of present-day Ukraine, however, was  held by Poland (1919-39). Ukraine suffered a severe famine in 1932-33  under Soviet leader Joseph Stalin; more than five million Ukrainians died  of starvation in an unprecedented peacetime catastrophe. Overrun by Axis  armies in 1941 during World War II, it was further devastated before being  retaken by the Soviets in 1944. In 1986 it was the site of the Chernobyl  accident at a Soviet-built nuclear power plant. Ukraine declared indepen�  dence in 1991. The turmoil it experienced in the 1990s as it attempted to  implement economic and political reforms culminated in the disputed  presidential election of 2004; invalidated by the Supreme Court after mass  protests, it ultimately led to a new runoff election that brought opposition  leader Viktor Yushchenko into office.</p><p>Ukrainian \yii-'kra-ne-3n\ language formerly Ruthenian  \ru-'the-ne-9n\ language Slavic language spoken by about 41 million  people in Ukraine, Poland, Slovakia, Russia, and in enclaves around the  world.

They can be generated or detected by  piezoelectric transducers (see piezoelectricity). High-power ultrasonics pro�  duce distortion in a medium; applications include ultrasonic welding,  drilling, irradiation of fluid suspensions (as in wine clarification), clean�  ing of surfaces (such as jewelry), and disruption of biological structures.  Low-power ultrasonic waves do not cause distortions; uses include sonar,  structure testing, and medical imaging and diagnosis. Some animals,  including bats, employ ultrasonic echolocation for navigation.</p><p>ultrasound or ultrasonography Use of ultrasonic waves to pro�  duce images of body structures. The waves travel through tissues and are  reflected back where density differs (e.g., the border between a hollow  organ�s wall and its inside). The reflected echoes are received by an elec�  tronic apparatus that measures their intensity level and the position of the  tissue reflecting them. The results can be displayed as still images or as a  moving picture of the inside of the body. Unlike X-rays or other ionizing  radiation, ultrasound carries minimal, if any, risk. Most often used during  pregnancy to examine the fetus, ultrasound imaging is also used on internal  organs and on the eye, breast, and major blood vessels. It can often show  whether a growth is benign or malignant. See also diagnostic imaging.</p><p>ultraviolet astronomy Study of astronomical objects and phenom�  ena by observing the ultraviolet radiation (UV radiation) they emit. It has  yielded much information about chemical abundances and processes in  interstellar matter, the Sun, and other stellar objects, such as hot young  stars and white dwarf stars. Ultraviolet astronomy became feasible once  rockets could carry instruments above Earth�s atmosphere, which absorbs  most electromagnetic radiation of UV wavelengths. Since the early 1960s,  a number of unmanned space observatories carrying UV telescopes,  including the Hubble Space Telescope, have collected UV data on objects  such as comets, quasars, NEBUiAe, and distant star clusters. The Extreme  Ultraviolet Explorer, launched in 1992, was the first orbiting observatory  to map the sky in the shortest UV wavelengths, at the boundary with the  X-ray region of the electromagnetic spectrum.</p><p>ultraviolet radiation Portion of the electromagnetic spectrum extend�  ing from the violet end of visible light to the X-ray region. Ultraviolet  (UV) radiation lies between wavelengths of about 400 nanometres and 10  nanometres, corresponding to frequencies of 7.5 x 10 14 Hz to 3 x 10 16  Hz. Most UV rays from the Sun are absorbed by the Earth�s ozone layer.  UV has low penetrating power, so its effects on humans are limited to the  skin. These effects include stimulation of production of vitamin D, sun�  burn, suntan, aging signs, and carcinogenic changes. UV radiation is also  used to treat jaundice in newborns, to sterilize equipment, and to produce  artificial light.</p><p>Ulysses See Odysseus</p><p>( Umar ibn al-Khattab Vu-mar- 1 ib-nul-kat- , tab\ (b. c. ad 586, Mecca,  Arabian Peninsula�d.

However, a tariff war with  France led to economic difficulties (1888), and Umberto�s colonial policy  in Africa was ended by Italy�s defeat by Ethiopia (1896). Facing increasing  social unrest, he supported the imposition of martial law (1898) and created  a period of turmoil that culminated in his assassination by an anarchist.</p><p>Umberto II (b. Sept. 15, 1904, Racconigi, Italy�d. March 18, 1983,  Geneva, Switz.) Prince of Savoy and briefly king of Italy (1946). Son of  Victor Emmanuel III, he commanded an Italian army division in World War  II. In May 1946 his father abdicated in his favour, but Umberto was him�  self forced to abdicate in June after the Italian people voted for a repub�  lic. He and his male heirs were permanently banished from Italy (though  the ban was lifted in 2002), and he settled in Portugal.</p><p>Umbria Region (pop., 2001 prelim.: 815,588), central Italy. It is located  on 3,265 sq mi (8,456 sq km) in the Apennines; its capital is Perugia.  Originally inhabited by the ancient Italic Umbrian tribe, it came under  Rome c. 300 bc and was made one of its administrative regions in the 1st  century ad. During the Christian era it became part of the Papal States. It  was the seat of the 15th-16th-century Umbrian school of painting, which  included Perugino and Pinturicchio, and was the home of St. Francis of  Assisi. Agriculture is an economic mainstay, while its industries produce  steel, chemicals, and textiles.</p><p>Umbrian Any member of an ancient pre-Etruscan people pushed into  central Italy (Umbria) by the Etruscans and Gauls. They never fought an  important war with the Romans. In the Social War they were among the  first to make peace with Rome. They are described by ancient authors as  being similar to their Etruscan enemies in culture. The Umbrian alphabet  is undoubtedly of Etruscan origin. Their dialect was Indo-European.</p><p>Umbrian Vsm-bre-onV language Ancient Italic language spoken in  central Italy in the last few centuries bc. Umbrian was related closely to  Oscan and Volscian and more distantly to Latin. It was displaced by Latin  at an unknown date. Modern knowledge of the language is derived almost  entirely from the Iguvine Tables (c. 300-90 bc).</p><p>UN See United Nations</p><p>Un-American Activities Committee, House See House  Un-American Activities Committee</p><p>Unabomber See Theodore Kaczynski</p><p>Unamuno V.ii-na-'mu-noX (y Jugo), Miguel de (b. Sept. 29, 1864,  Bilbao, Spain�d. Dec. 31, 1936, Salamanca) Spanish philosopher and  writer. He served twice as rector of the University of Salamanca (1901�  14; 1931-36); he was dismissed first for espousing the Allied cause in  World War I and later for denouncing Francisco Franco�s Falangists.  Though he also wrote poetry and plays, he was most influential as an  essayist and novelist. In The Tragic Sense of Life in Men and Peoples  (1913), he stressed the role spiritual anxiety plays in driving one to live  the fullest possible life. His most famous novel is Abel Sanchez (1917),  a modem re-creation of the biblical story of Cain and Abel. The Christ  of Velazquez (1920), a study in poetic form of the great Spanish painter,  is a superb example of modem Spanish verse.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1962 I uncertainty principle &#x25BA; ungulate</p><p>uncertainty principle or Heisenberg uncertainty principle  or indeterminacy principle Principle that states that the position and  velocity of an object cannot both be measured exactly at the same time,  and that the concepts of exact position and exact velocity together have  no meaning in nature. Articulated by Werner Heisenberg in 1927, it applies  only at the small scales of atoms and subatomic particles and is not notice�  able for macroscopic objects, such as moving vehicles. Any attempt to  measure the velocity of a subatomic particle precisely will displace the  particle in an unpredictable way, thus invalidating any simultaneous mea�  surement of its position. This displacement is a result of the wave nature  of particles (see wave-particle duality). The principle also applies to other  related pairs of variables, such as energy and time.</p><p>Uncle Sam Popular U.S. symbol, usually associated with a cartoon fig�  ure having long white hair and chin  whiskers and dressed in a swallow�  tailed coat, vest, tall hat, and striped  trousers.

The  existence of unconscious mental activities was first elaborated by Sigmund  Freud and is now a well-established principle of psychiatry. The origin of  many neurotic symptoms is said to depend on conflicts that have been  removed from consciousness by repression and maintained in the uncon�  scious through various defense mechanisms. Recent biopsychological explo�  rations have shed light on the relationship between brain physiology and  the levels of consciousness at which people retain memories.</p><p>underground See subway  Underground See Resistance</p><p>Underground Railroad Secret system in northern U.S. states to help  escaping slaves. Its name derived from the need for secrecy and the railway  terms used in the conduct of the system. Various routes in 14 states, called  lines, provided safe stopping places (stations) for the leaders (conductors)  and their charges (packages) while fleeing north, sometimes to Canada.  The system developed in defiance of the Fugitive Slave Acts and was active  mainly from 1830 to 1860. An estimated 40,000 to 100,000 slaves used the  network. Assistance was provided mainly by free blacks, including Harriet  Tubman, and philanthropists, church leaders, and abolitionists. Its existence  aroused support for the antislavery cause and convinced Southerners that  the North would never allow slavery to remain unchallenged.</p><p>Undset Yiin-setV Sigrid (b. May 20, 1882, Kalundborg, Den.�d. June  10, 1949, Lillehammer, Nor.) Norwegian novelist. Her father was an  archaeologist, and her home life was steeped in legend, folklore, and Nor�  wegian history. Her early novels deal with the position of women in the  contemporary lower middle class. She then turned to the distant past and  created her masterpiece, the trilogy Kristin Lavransdatter (1920-22),  which is set in medieval Norway and depicts the spiritual growth of a  strong woman. Undset converted to Roman Catholicism in 1924. Her later  works, including the historical novel The Master of Hestviken (1925-27)  and novels on contemporary themes, reflect her interest in religion. She  received the Nobel Prize for Literature in 1928.</p><p>unemployment Condition of a person who is able to work, is actively  seeking work, but is unable to find any. Statistics on unemployment are</p><p>collected and analyzed by government labour offices in most countries  and are considered an important indicator of economic health. Since  World War II full employment has been a stated goal of many govern�  ments. Full employment is not necessarily synonymous with a zero unem�  ployment rate, since at any given time the unemployment rate will include  some people who are between jobs and not unemployed in any long-term  sense. Underemployment is the term used to describe the situation of those  who are able to find employment only for shorter than normal periods�  for example, part-time workers and seasonal workers�and may also  describe the condition of workers whose education or training makes them  overqualified for their jobs.</p><p>unemployment insurance Form of social insurance designed to  compensate workers for short-term, involuntary unemployment. It was  created primarily to provide financial assistance to laid-off workers dur�  ing a period deemed long enough to allow them to find another job or to  be rehired at their original job. In most countries, workers who are per�  manently disabled or who have been unemployed for a long period of  time are covered under other plans. In countries such as Canada and Brit�  ain, workers in any occupation may qualify for unemployment insurance;  the U.S. denies coverage to certain workers, such as government employ�  ees and the self-employed. In most countries, benefits are related to earn�  ings and are paid for a limited period of time. Funding may come out of  general government revenues or from specific taxes placed on employers  or employees.</p><p>UNESCO in full United Nations Educational, Scientific and  Cultural Organization Specialized agency of the UN, created in  1946 to aid peace by promoting international cooperation in education,  science, and culture. It supports member states� efforts to eliminate illit�  eracy, encouraging the extension of free education, and acts as a clear�  inghouse for the exchange of ideas and knowledge. In 1972 it sponsored  an international agreement to establish a World Heritage list of cultural  sites and natural areas that would enjoy government protection (see World  Heritage site). In 1984 the U.S. withdrew from UNESCO to protest what  it considered the agency�s anti-Western approach to cultural issues; the  United Kingdom and Singapore withdrew a year later. The United King�  dom rejoined in 1997, and the U.S. followed suit in 2003.</p><p>uneven parallel bars Event in women�s gymnastics in which a pair  of wooden bars supported horizontally above the floor at different heights  is used to perform acrobatic feats. The apparatus allows a great variety  of movements, but hanging and swinging exercises predominate. It  became an Olympic event in 1936. See also parallel bars.</p><p>Ungaretti \,uq-ga-'rat-te\, Giuseppe (b. Feb. 10, 1888, Alexandria,  Egypt�d. June 1, 1970, Milan, Italy) Egyptian-Italian poet. He lived in  Alexandria until he was 24, and the desert regions of Egypt provide  recurring images in his work. While studying in Paris, he was strongly  influenced by the poets of the Symbolist movement. He was the founder of  Hermeticism, which began with his II porto sepolto (1916; �The Buried  Port�) and brought about a reorientation in modem Italian poetry. Though  experimental, his poetry developed in a coherent direction in Allegria di  naufragi (1919; �Gay Shipwrecks�) and later collections. After World War  II his works became more structured and acquired a more straightforward  tone.</p><p>Ungava \on-'ga-v9-\ Bay Inlet, southern Hudson Strait, northeastern  Quebec, Canada. It is about 200 mi (320 km) long and 160 mi (260 km)  wide at its mouth, with a maximum depth of 978 ft (298 m). Fed by sev�  eral large rivers, including the Koksoak, Leaf, and Payne, it is ice-free  only four months a year. At its mouth, Akpatok Island (551 sq mi [1,427  sq km]) rises to 930 ft (283 m).</p><p>Ungava Peninsula Northern part of New Quebec district, northern  Quebec, Canada. It is bounded by the Hudson Strait, Ungava Bay, Labra�  dor, the Eastmain River, and Hudson Bay.

It was awarded the Nobel Prize for  Peace in 1965. UNICEF has focused its efforts on areas in which rela�  tively small expenditures can have a significant impact on the lives of the  most disadvantaged children, such as the prevention and treatment of dis�  ease.

The Unicode  Worldwide Character Standard includes letters, digits, diacritics, punctua�  tion marks, and technical symbols for all the world�s principal written  languages, using a uniform encoding scheme. The first version of Uni�  code was introduced in 1991; the most recent version contains almost  50,000 characters. Numerous encoding systems (including ASCII) predate  Unicode. With Unicode (unlike earlier systems), the unique number pro�  vided for each character remains the same on any system that supports  Unicode.</p><p>unicorn Mythological animal resembling a white horse with a single  horn on its forehead. The unicorn  was depicted in Mesopotamian art  and was referred to in the ancient  myths of India and China. Its earli�  est description in Greek literature  dates from c. 400 bc and probably  refers to the Indian rhinoceros. The  unicorn was believed to be fierce and  difficult to capture, but if a virgin  were brought before it, it would lay  its head in the virgin�s lap. Its horn  was thought to offer protection  against poison. Medieval writers  associated the unicorn with Jesus,  and the hunt for the unicorn was  often represented in medieval art.</p><p>unidentified flying object  (UFO) Aerial object or optical phe�  nomenon not readily explainable to  the observer. Interest in UFOs  increased with developments in  aeronautics and astronautics after  World War II. A U.S. government  panel investigating sightings in the  1950s reported that 90% coincided  with astronomical or meteorological  phenomena or sightings of aircraft,  birds, or hot gases, sometimes under  unusual weather conditions. Some remained unexplained, however, and  in the mid 1960s a few scientists concluded that a small percentage indi�  cated the presence of extraterrestrial visitors. This sensational hypothesis,  promoted in the press, met with prompt resistance from other scientists.  A U.S. Air Force UFO study begun in 1968 firmly rejected the extrater�  restrial hypothesis, but a large fraction of the public, and a few scientists,  continued to support it. UFO reports vary widely in reliability. The  unaided eye is easily fooled; radar sightings of UFOs, more reliable in  some ways, may fail to distinguish physical objects from meteor trails,  rain, or thermal discontinuities and are subject to radio interference.

Influenced by yin-yang prin�  ciples and Korean shamanism, it seeks to establish divine rule on earth  through the restoration of the family, based on the union of the Lord and  Lady of the Second Advent (believed to be Moon and his wife, Hak Ja  Han). It strives to fulfill what it asserts to be the uncompleted mission of  Jesus �procreative marriage. The church has been criticized for its recruit�  ment policies (said to include brainwashing) and business practices. Its</p><p>mass marriage ceremonies have gained press attention. Its worldwide  membership is about 200,000 in more than 100 countries.</p><p>unified field theory Attempt to describe all fundamental interactions  between elementary particles in terms of a single theoretical framework  (a �theory of everything�) based on quantum field theory. So far, the weak  force and the electromagnetic force have been successfully united in elec-  troweak theory, and the strong force is described by a similar quantum  field theory called quantum chromodynamics. However, attempts to unite  the strong and electroweak theories in a grand unified theory have failed,  as have attempts at a self-consistent quantum field theory of gravitation.</p><p>unified science or unity-of-science view In the philosophy of  logical positivism, the doctrine holding that all sciences share the same lan�  guage, laws, and method. The unity of language has been taken to mean  either that all scientific statements could be restated as a set of protocol  sentences describing sense-data or that all scientific terms could be defined  using physics terms. The unity of law means that the laws of the various  sciences must be deduced from some set of fundamental laws (e.g., those  of physics). The unity of method means that the procedures for support�  ing statements in the various sciences are basically the same. The unity-  of-science movement that arose in the Vienna Circle held to those three  unities, and Rudolf Carnap�s �physicalism� supported the notion that all  the terms and statements of empirical science could be reduced to terms  and statements in the language of physics.</p><p>uniform circular motion Motion of a particle moving at a constant  speed on a circle. Though the magnitude of the velocity of such an object  may be constant, the object is constantly accelerating because its direc�  tion is constantly changing. At any given instant its direction is perpen�  dicular to a radius of the circle drawn to the point of location of the object  on the circle. The acceleration is strictly a change in direction and is a  result of a force directed toward the centre of the circle. This centripetal  force causes centripetal acceleration.</p><p>Uniform Resource Locator See URL</p><p>uniformitarianism Doctrine in geology that physical, chemical, and  biologic processes now at work on and within the Earth have operated  with general uniformity (in the same manner and with essentially the same  intensity) through immensely long periods of time and are sufficient to  account for all geologic change. In other words, the present is the key to  the past. Although the term is no longer much used, the principle, origi�  nated by James Hutton, is fundamental to geologic thinking and underlies  the whole development of the science of geology.

The Irish parliament resisted the proposal, which called for its  abolition, but votes bought by cash or honours ensured passage of the  agreement in 1800. The union remained until the recognition of the Irish  Free State (excluding six of the counties of the northern province of  Ulster) by the Anglo-Irish treaty concluded on Dec. 6, 1921; the union  officially ended on Jan. 15, 1922.</p><p>Unicorn, detail from "The Lady and the  Unicorn" tapestry, late 15th century; in  the Musee de Cluny, Paris</p><p>GIRAUDON/ART RESOURCE</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1964 I Union Islands &#x25BA; United Arab Emirates</p><p>Union Islands See Tokelau</p><p>Union League Association formed to inspire loyalty to the Union cause  in the American Civil War.

It consisted, in its final years, of 15 soviet socialist republics that gained  independence at its dissolution: Armenia, Azerbaijan, Belorussia (now  Belarus), Estonia, Georgia (now Republic of Georgia), Kazakhstan, Kir�  gizia (now Kyrgyzstan), Latvia, Lithuania, Moldavia (now Moldova), Rus�  sia, Tajikistan, Turkmenistan, Ukraine, and Uzbekistan. It also contained 20  autonomous soviet socialist republics: 16 within Russia, 2 within Geor�  gia, 1 within Azerbaijan, and 1 within Uzbekistan. Capital: Moscow.  Stretching from the Baltic and Black seas to the Pacific Ocean and encom�  passing some 8,650,000 sq mi (22,400,000 sq km), the Soviet Union con�  stituted the largest country on Earth, having a maximum east-west extent  of about 6,800 mi (10,900 km) and a maximum north-south extent of  about 2,800 mi (4,500 km). It encompassed 11 time zones and had com�  mon boundaries with 6 European countries and 6 Asian countries. Its  regions contained fertile lands, deserts, tundra, high mountains, some of  the world�s longest rivers, and large inland waters, including most of the  Caspian Sea. The coastline on the Arctic Ocean extended 3,000 mi (4,800  km), while that on the Pacific was 1,000 mi (1,600 km) long. The U.S.S.R.  was an agricultural, mining, and industrial power. Following the Russian  Revolution of 1917, four socialist republics were established on the ter�  ritory of the former Russian Empire: the Russian Soviet Federated Social�  ist Republic, the Transcaucasian Soviet Federated Socialist Republic, the  Ukrainian Soviet Socialist Republic, and the Belorussian Soviet Socialist  Republic. These four constituent republics established the Union of Soviet  Socialist Republics in 1922, to which other republics subsequently were  added. A power struggle begun in 1924 with the death of communist  leader Vladimir Lenin ended in 1927 when Joseph Stalin gained victory.  Implementation of the first of the Five-Year Plans in 1928 centralized indus�  try and collectivized agriculture. A purge in the late 1930s resulted in the  imprisonment or execution of millions of persons considered dangerous  to the state (see purge trials). After World War II, with their respective  allies, the U.S.S.R. and the U.S. engaged in the Cold War. In the late  1940s the U.S.S.R. helped to establish communist regimes throughout  most of eastern Europe. The U.S.S.R. exploded its first atomic bomb in  1949 and its first hydrogen bomb in 1953. Following Stalin�s death, it  experienced limited political and cultural liberalization under Nikita  Khrushchev. It launched the first manned orbital spaceflight in 1961. Under  Leonid Brezhnev liberalization was partially reversed, but in the mid-1980s  Soviet leader Mikhail Gorbachev instituted the liberal policies called glas-  nost and perestroika. By the end of 1990 the communist government had  toppled, and a program to create a market economy had been imple�  mented. The U.S.S.R. was officially dissolved on Dec. 25, 1991.</p><p>Union Pacific Corp. Company that extended the U.S. railway system  to the Pacific Coast. Incorporated by an act of Congress in 1862, it was  built westward 1,006 mi (1,620 km) from Omaha, Neb., to meet the Cen�  tral Pacific Railroad, which was being built eastward from Sacramento,  Calif. The two railroads were joined at Promontory, Utah, in 1869. The  Union Pacific was largely financed by federal loans and land grants, but  its involvement in the Credit Mobilier scandal left it badly in debt, and the  company went into receivership in 1893. It was reorganized in 1897 by  Edward H. Harriman, under whose leadership the railroad took part in the  economic development of the West. In 1982 it merged with the Missouri  Pacific Railroad Co. and the Western Pacific Railroad Co. Its acquisition  of the Southern Pacific Rail Corp. in 1996 made it the largest railroad in  the U.S., with control of almost all rail-based shipping in the western  two-thirds of the country.</p><p>union shop Arrangement under which workers are required to join a  particular union within a specified period of time after beginning employ�  ment. Such an arrangement differs from the closed shop in that the employ�  er�s choice of new employees is not restricted to union members.

Union</p><p>shops are uncommon in most countries, but they are both legal and com�  mon in the U.S. and Japan.

They are the emirates of AbG  ZabT (Abu Dhabi), Dubayy (Dubai), �Ajman, Al-Shariqah (Sharjah), Umm  al-Qaywayn, Ra�s al-Khaymah, and Al-Fujayrah. Area: 32,280 sq mi  (83,600 sq km). Population (2005 est.): 4,690,000. Capital: Abu Dhabi. The  indigenous inhabitants are Arabs, but there are a large number of South  Asian and Iranian migrant workers. Languages: Arabic (official), English,  Persian, Urdu, Hindi. Religions: Islam (official; predominantly Sunni);  also Christianity, Hinduism. Currency: UAE dirham. The UAE�s low-  lying desert plain is broken by the Hajar Mountains along the Musandam  Peninsula. Three natural deepwater harbours are located along the Gulf of  Oman. The UAE (mainly Abu ZabI) has roughly one-tenth of the world�s  petroleum reserves and significant natural gas deposits, the production of  which are the federation�s principal industries. Other important economic  activities include fishing, livestock herding, and date production. The fed�  eration has one appointive advisory board; its chief of state is the presi�  dent, and the head of government is the prime minister.

The states formed the Trucial  States Council in 1960 and in 1971 termi�  nated defense treaties with Britain and established the six-member fed�  eration. Ra�s al-Khaymah joined it in 1972. The UAE aided coalition  forces against Iraq in the First Persian Gulf War (1991).</p><p>United Arab Republic See Egypt</p><p>United Artists Corp. U.S. film company. It was founded in 1919 by  Charlie Chaplin, Mary Pickford, Douglas Fairbanks, and D.W. Griffith so that  they could produce and distribute their own movies and distribute other  independently produced movies. The first major production company con�  trolled by its artists, it prospered with the films of its founders, including  The Gold Rush (1925), and those of producers such as Samuel Goldwyn,  Howard R. Hughes, and Alexander Korda. After 1951 it became mainly a  distributor, releasing successful movies such as High Noon (1952), Some  Like It Hot (1959), and West Side Story (1961). It was sold to TransAmer-  ica Corp. in 1967 and resold to MGM in 1981. By the late 20th century  United Artists was a specialty films division of MGM, producing movies  such as Leaving Las Vegas (1995), The Birdcage (1996), and Tea with  Mussolini (1999).</p><p>United Automobile Workers (UAW) in full International  Union, United Automobile, Aerospace, and Agricultural  Implement Workers of America U.S.-based industrial union rep�  resenting automotive and other vehicular workers in the U.S., Canada,  and Puerto Rico. The UAW was founded in Detroit, Mich., in 1935, when  the Committee for Industrial Organization (see AFL-CIO) began to orga�  nize automotive workers. The union successfully countered automakers�  initial resistance with sit-down strikes and a 1937 Supreme Court deci�  sion upholding the right to organize as declared in the Wagner Act. Gen�  eral Motors Corp. was the first to recognize the UAW, and most other  automakers followed suit, though Ford Motor Co. continued to resist until  1941. Under Walter Reuther, the union won contracts providing for cost-  of-living adjustments, health plans, and paid vacations. Reuther�s friction  with George Meany led the UAW to withdraw from the AFL-CIO in 1968.  A short-lived alliance with the Teamsters was dissolved in 1972, and the  UAW rejoined the AFL-CIO in 1981. Toward the end of the 20th century,  the union�s bargaining strength was eroded by an increasingly global  labour market, effectively reducing the wages and benefits manufacturers  were willing to pay American workers.</p><p>United Fruit Co, Historic U.S.-based produce company that became  Chiquita Brands International, Inc., in 1990. It was founded in 1899 when</p><p>the Boston Fruit Co. merged with other companies selling bananas grown  in Central America, Colombia, and the Caribbean. Minor C. Keith, its  principal founder, gained extensive land rights in Costa Rica in return for  constructing railroads. United Fruit became the largest employer in Cen�  tral America, developing vast tracts of jungle lands and building one of  the largest private merchant navies in the world. Its exploitation of cor�  rupt Central American politicians dependent on income from the banana  business led to the term banana republic. Attacked in the Latin Ameri�  can press as el pulpo (�the octopus�), the company was widely accused  of exploiting workers and influencing governments during the era of �dol�  lar diplomacy� in the early to mid-20th century. United Fruit later trans�  ferred portions of its landholdings to individual growers. �Miss Chiquita,�  its well-known trademark, was introduced in 1944. The familiar blue  Chiquita stickers were first applied to the company�s bananas in 1963. In  1970 United Fruit merged with AMK Corp. to form United Brands Co.,  which took the Chiquita name in 1990. In the early 21st century the com�  pany concentrated its efforts on produce, notably bananas and packaged  salads.</p><p>United Kingdom of Great Britain and Northern Ireland or  United Kingdom or Great Britain Island country, western Europe,  North Atlantic Ocean.

Tin and iron ore deposits, once central to the economy, have  become exhausted or uneconomical, and the coal industry, long a staple  of the economy, began a steady decline in the 1950s that worsened with  pit closures in the 1980s. Offshore petroleum and natural gas reserves are  significant. Chief crops are barley, wheat, sugar beets, and potatoes. Major  manufactures include motor vehicles, aerospace equipment, electronic  data-processing and telecommunication equipment, and petrochemicals.  Fishing and publishing also are important economic activities. The U.K.  is a constitutional monarchy with two legislative houses; its chief of state  is the sovereign, and the head of government is the prime minister.</p><p>The early pre-Roman inhabitants of Britain (see Stonehenge) were  Celtic-speaking peoples, including the Brythonic people of Wales, the  Piets of Scotland, and the Britons of Britain. Celts also settled in Ireland  c. 500 bc. Julius Caesar invaded and took control of the area in 55-54 bc.  The Roman province of Britannia endured until the 5th century ad and  included present-day England and Wales. Germanic tribes, including  Angles, Saxons, and Jutes, invaded Britain in the 5th century. The inva�  sions had little effect on the Celtic peoples of Wales and Scotland. Chris�  tianity began to flourish in the 6th century. During the 8th and 9th  centuries, Vikings, particularly Danes, raided the coasts of Britain. In the  late 9th century Alfred the Great repelled a Danish invasion, which helped  bring about the unification of England under Athelstan. The Scots attained  dominance in Scotland, which was finally unified under Malcolm II (1005-  34). William of Normandy (see William I) took England in 1066. The Nor�  man kings established a strong central government and feudal state. The  French language of the Norman rulers eventually merged with the Anglo-  Saxon of the common people to form the English language. From the 11th  century, Scotland came under the influence of the English throne. Henry  II conquered Ireland in the late 12th century. His sons Richard I and John  had conflicts with the clergy and nobles, and eventually John was forced  to grant the nobles concessions in the Magna Carta (1215). The concept  of community of the realm developed during the 13 th century, providing  the foundation for parliamentary government. During the reign of Edward  I (1272-1307), statute law developed to supplement English common law,  and the first Parliament was convened. In 1314 Robert the Bruce (see Rob�  ert I) won independence for Scotland. The house of Tudor became the rul�  ing family of England following the Wars of the Roses (1455-85). Henry  VIII (1509�47) established the Church of England and incorporated Wales  as part of England.</p><p>The reign of Elizabeth I (1558-1603) began a period of colonial expan�  sion; in 1588 British forces defeated the �invincible� Spanish Armada. In  1603 James VI of Scotland ascended the English throne, becoming James  I, and established a personal union of the two kingdoms. The English Civil  Wars erupted in 1642 between Royalists and Parliamentarians, ending in  the execution of Charles I (1649). After 11 years of Puritan rule under  Oliver Cromwell and his son (1649-60), the monarchy was restored with  Charles II. In 1689, following the Glorious Revolution, Parliament pro�  claimed the joint sovereigns William III and Mary II. who accepted the  British Bill of Rights. In 1707 England and Scotland assented to the Act  of Union, forming the kingdom of Great Britain. The Hanoverians  ascended the English throne in 1714, when George Louis, elector of  Hanover, became George I of Great Britain. During the reign of George  III, Great Britain�s North American colonies won independence (1783).  This was followed by a period of war (1789-1815) with Revolutionary  France and later with the empire of Napoleon. In 1801 legislation united  Great Britain with Ireland to create the United Kingdom of Great Britain  and Ireland. Britain was the birthplace of the Industrial Revolution in the  late 18th century, and it remained the world�s foremost economic power  until the late 19th century. During the reign of Queen Victoria (1837�  1901), Britain�s colonial expansion reached its zenith, though the older  dominions, including Canada and Australia, were granted independence  (1867 and 1901, respectively).</p><p>The U.K. entered World War I allied with France and Russia in 1914.  Following the war, revolutionary disorder erupted in Ireland, and in 1921  the Irish Free State (see Ireland) was granted dominion status. Six coun�  ties of Ulster, however, remained in the U.K. as Northern Ireland. The  U.K. entered World War II in 1939. Following the war, the Irish Free State  became the Irish republic and left the Commonwealth. India also gained  independence from the U.K. Throughout the postwar period and into the  1970s, the U.K. continued to grant independence to its overseas colonies</p><p>British Sovereigns</p><p>Kings of Wessex</p><p>Richard II (P)</p><p>1377-99</p><p>Egbert (S)</p><p>802-39</p><p>Henry IV (P:L)</p><p>1399-1413</p><p>Aethelwulf (S)</p><p>839-56/58</p><p>Henry V (P:L)</p><p>1413-22</p><p>Aethelbald (S) 855/56-60</p><p>Henry VI (P:L)</p><p>1422-61</p><p>Aethelberht (S)</p><p>860-65/66</p><p>Edward IV (P:Y)</p><p>1461-70</p><p>Aethelred 1 (S) 865/66-71</p><p>Henry VI 2</p><p>1470-71</p><p>Alfred the Great (S)</p><p>871-99</p><p>Edward IV 2</p><p>1471-83</p><p>Edward the Elder (S)</p><p>899-924</p><p>Edward V (P:Y)</p><p>1483</p><p>Sovereigns of England</p><p>Richard III (P:Y)</p><p>1483-85</p><p>Athelstan 1 (S)</p><p>925-39</p><p>Henry VII (T)</p><p>1483-1509</p><p>Edmund 1 (S)</p><p>939-46</p><p>Henry VIII (T)</p><p>1509-1547</p><p>Eadred (S)</p><p>946-55</p><p>Edward VI (T)</p><p>1547-53</p><p>Eadwig (S)</p><p>955-59</p><p>Mary 1 (T)</p><p>1553-58</p><p>Edgar(S)</p><p>959-75</p><p>Elizabeth 1 (T)</p><p>1558-1603</p><p>Edward the Martyr (S)</p><p>975-78</p><p>Sovereigns of Great</p><p>Ethel red II the</p><p>Britain and the</p><p>Unready (S)</p><p>978-1013</p><p>United Kingdom</p><p>Sweyn Forkbeard (D)</p><p>1013-14</p><p>James 1 (VI of</p><p>Ethel red II the</p><p>Scotland) (St)</p><p>1603-25</p><p>Unready 2 (S)</p><p>1014-16</p><p>Charles 1 (St)</p><p>1625-49</p><p>Edmund II Ironside (S)</p><p>1016</p><p>Commonwealth</p><p>Canute (D)</p><p>1016-35</p><p>Oliver Cromwell</p><p>1653-58</p><p>Harold 1 Harefoot (D)</p><p>1035-40</p><p>Richard Cromwell</p><p>1658-59</p><p>Hardecanute (D)</p><p>1040-42</p><p>Charles II (St)</p><p>1660-85</p><p>Edward the</p><p>James II (St)</p><p>1685-88</p><p>Confessor (S)</p><p>1042-66</p><p>William III &amp;</p><p>Harold II (S)</p><p>1066</p><p>Mary II (O/St)</p><p>1689-1702 3</p><p>William 1 the</p><p>Anne (St)</p><p>1702-14</p><p>Conqueror (N)</p><p>1066-87</p><p>George 1(H)</p><p>1714-27</p><p>William II (N)</p><p>1087-1100</p><p>George II (H)</p><p>1727-60</p><p>Henry 1 (N)</p><p>1100-35</p><p>George III (H)</p><p>1760-1820</p><p>Stephen (B)</p><p>1135-54</p><p>George IV (H)</p><p>1820-30</p><p>Henry II (P)</p><p>1154-89</p><p>William IV (H)</p><p>1830-37</p><p>Richard 1 (P)</p><p>1189-99</p><p>Victoria (H)</p><p>1837-1901</p><p>John (P)</p><p>1199-1216</p><p>Edward VII (SCG)</p><p>1901-10</p><p>Henry III (P)</p><p>1216-72</p><p>George V (W)</p><p>1910-36</p><p>Edward 1 (P)</p><p>1272-1307</p><p>Edward VIII (W)</p><p>1936 4</p><p>Edward II (P)</p><p>1307-27</p><p>George VI (W)</p><p>1936-52</p><p>Edward III (P)</p><p>1327-77</p><p>Elizabeth II (W)</p><p>1952-</p><p>Dynasty or house: S=Saxon, D=Danish, N=Norman, B=Blois,</p><p>P=Plantagenet, L=Lancaster, Y=York, T=Tudor, St=Stuart, 0=0range,</p><p>H=Hanover, SCG=Saxe-Coburg-Gotha, W=Windsor  'Athelstan was king of Wessex and the first king of all England.</p><p>Restored</p><p>3 William and Mary, as husband and wife, reigned jointly until Mary's death  in 1694.</p><p>4 Edward VIII succeeded on the death of his father on January 20, 1936, but  abdicated on December 11 before his coronation.</p><p>and dependencies.

Lewis took over, the union had half  a million members. Lewis capitalized on the pro-labour climate of the  New Deal and led numerous strikes to win fair pay, safe working condi�  tions, and benefits. The UMWA was a mainstay of the Congress of Indus�  trial Organizations (see AFL-CIO) in its early years, but Lewis withdrew  the union from the CIO in 1942.

It also  has 14 specialized agencies�some inherited from its predecessor, the  League of Nations (e.g., the International Labour Organization) �and a  number of special offices (e.g., the Office of the United Nations High Com�  missioner for Refugees), programs, and funds (e.g., UNICEF). The UN is  involved in economic, cultural, and humanitarian activities and the coor�  dination or regulation of international postal services, civil aviation,  meteorological research, telecommunications, international shipping, and  intellectual property.

UNCTAD�s principal functions include the promotion of  trade between countries in different stages of development and with dif�  ferent economic systems, initiation of negotiations for trade agreements,  and the formulation of international trade policies. In the late 20th and  early 21st centuries, UNCTAD�s efforts were directed toward the prob�  lems created in developing countries by economic globalization, and spe�  cial attention was given to measures to help the poorest and least-  developed countries become integrated into the world economy.</p><p>United Nations Development Programme (UNDP) UN orga�  nization formed in 1965 to promote environmentally sustainable human  development in low-income countries.

Since the 1980s it has emphasized disaster  preparedness and prevention, and it has assisted in executing projects of  the United Nations Development Programme.</p><p>United Nations Relief and Rehabilitation Administration</p><p>Administrative body (1943^47) for an extensive social-welfare program  for war-ravaged nations. It distributed relief supplies and services, includ�  ing shelter, food, and medicine, and helped with agricultural and economic  rehabilitation. Its functions were later taken over by the International  Refugee Organization, the World Health Organization, and UNICEF.</p><p>United Nations Resolution 242 Resolution of the United Nations  Security Council that ended the 1967 Six-Day War. The Israelis supported  the resolution because it called on the Arab states to accept Israel�s right  �to live in peace within secure and recognized boundaries free from  threats or acts of force.� All Arab states eventually accepted it (Egypt and  Jordan accepted the resolution from the outset) because of its clause call�  ing for Israel to withdraw from the territories conquered in 1967. The Pal�  estine Liberation Organization rejected it until 1988 because it lacked  explicit references to Palestinians. Though never fully implemented, it  was the basis of diplomatic efforts to end Arab-Israeli conflicts until the  Camp David Accords and remains an important touchstone in any negoti�  ated resolution to the Arab-Israeli conflict.</p><p>United Nations Secretariat Administrative body that coordinates  United Nations activities. Its staff, recruited on the basis of merit, is com�  posed of several thousand permanent professional experts from member  states, including translators, clerks, technicians, administrators, project  directors, and negotiators, who carry out the UN�s day-to-day operations  and administer the policies and programs set by the other divisions. They  are required to swear an oath of loyalty to the UN and must not take  instructions from their home governments.</p><p>United Nations Security Council Division of the United Nations  whose primary purpose is to maintain international peace and security.  The Security Council originally consisted of five permanent members�  Taiwan (succeeded in 1971 by China), France, the United Kingdom, the  U.S., and the Soviet Union (succeeded in 1991 by Russia)�and six rotat�  ing members elected by the United Nations General Assembly for two-year  terms. In 1965 the number of nonpermanent members was increased to  10. UN members agree to abide by the Security Council�s resolutions  when they join. The Security Council investigates disputes that threaten  international peace and advises on how to resolve them. To prevent or  halt aggression, it may impose diplomatic or economic sanctions or autho�  rize the use of military force. Each of the permanent members holds veto  power in decisions on substantive matters, such as the application of  sanctions. Decisions on both substantive and procedural matters require  nine affirmative votes, including the affirmative vote of all five permanent  members (though in practice a permanent member may abstain without  impairing the validity of a decision).</p><p>United Nations Trusteeship Council One of the main organs of  the UN, composed of the five permanent members of the Security Coun�  cil. It supervised the administration of trust (non-self-governing) territo�  ries, including former colonies in Africa and the Pacific. The council�s  job was to send inspection missions to the territories, examine petitions,  review reports, and make recommendations. It suspended operations after  the last trust territory, Palau, gained its sovereignty in 1994.</p><p>United Netherlands, Republic of the See Dutch Republic  United Provinces See Uttar Pradesh</p><p>United States officially United States of America Country, North  America.

Chief rivers are the Mississippi system, the  Colorado, the Columbia, and the Rio Grande. The Great Lakes, the Great  Salt Lake, Iliamna Lake, and Lake Okeechobee are the largest lakes. The  U.S. is among the world�s leading producers of several minerals, includ�  ing copper, silver, zinc, gold, coal, petroleum, and natural gas; it is the  chief exporter of food. Its manufactures include iron and steel, chemicals,  electronic equipment, and textiles. Other important industries are tourism,  dairying, livestock raising, fishing, and lumbering. The U.S. is a federal  republic with two legislative houses; its head of state and government is  the president.</p><p>The territory was originally inhabited for several thousand years by  numerous American Indian peoples who had probably emigrated from  Asia. European exploration and settlement from the 16th century began  displacement of the Indians. The first permanent European settlement, by  the Spanish, was at Saint Augustine, Fla., in 1565. The English settled</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>United States &#x25BA; United States Marine Corps I 1969</p><p>Jamestown, Va. (1607); Plymouth, Mass. (1620); Maryland (1634); and  Pennsylvania (1681). The English took New York, New Jersey, and Dela�  ware from the Dutch in 1664, a year after English noblemen had begun  to colonize the Carolinas. The British defeat of the French in 1763 (see  French and Indian War) assured Britain political control over its 13 colo�  nies. Political unrest caused by British colonial policy culminated in the  American Revolution (1775-83) and the Declaration of Independence  (1776). The U.S. was first organized under the Articles of Confederation  (1781), then finally under the Constitution (1787) as a federal republic.  Boundaries extended west to the Mississippi River, excluding Spanish  Florida. Land acquired from France by the Louisiana Purchase (1803)  nearly doubled the country�s territory. The U.S. fought the War of 1812  against the British and acquired Florida from Spain in 1819. In 1830 it  legalized the removal of American Indians to lands west of the Missis�  sippi River. Settlement expanded into the Far West in the mid-19th cen�  tury, especially after the discovery of gold in California in 1848 (see gold  rush). Victory in the Mexican War (1846^48) brought the territory of seven  more future states (including California and Texas) into U.S. hands. The  northwestern boundary was established by treaty with Britain in 1846.  The U.S. acquired southern Arizona by the Gadsden Purchase (1853). It  suffered disunity during the conflict between the slavery-based plantation  economy in the South and the industrial and agricultural economy in the  North, culminating in the American Civil War and the abolition of slavery  under the 13th Amendment. After Reconstruction (1865-77) the U.S.  experienced rapid growth, urbanization, industrial development, and  European immigration. In 1887 it authorized allotment of American  Indian reservation land to individual tribesmen, resulting in widespread  loss of land to whites. Victory in the Spanish-American War brought the  U.S. the overseas territories of the Philippines, Guam, and Puerto Rico.  By the end of the 19th century, it had further developed foreign trade and  acquired other outlying territories, including Alaska, Midway Island, the  Hawaiian Islands, Wake Island, American Samoa, and the Panama Canal  Zone.</p><p>The U.S. participated in World War I in 1917-18. It granted suffrage  to women in 1920 and citizenship to American Indians in 1924. The stock  market crash of 1929 led to the Great Depression, which New Deal leg�  islation combated by increasing the federal government�s role in the  economy. The U.S. entered World War II after the Japanese bombing of  Pearl Harbor (Dec. 7, 1941). The explosion by the U.S. of an atomic bomb  on Hiroshima (Aug. 6, 1945) and another on Nagasaki (Aug. 9, 1945),  Japan, brought about Japan�s surrender. Thereafter the U.S. was the mili�  tary and economic leader of the Western world. In the first decade after  the war, it aided the reconstruction of Europe and Japan and became  embroiled in a rivalry with the Soviet Union known as the Cold War. It  participated in the Korean War from 1950 to 1953. In 1952 it granted  autonomous commonwealth status to Puerto Rico. Racial segregation in  schools was declared unconstitutional in 1954. Alaska and Hawaii were  made states in 1959. In 1964 Congress passed the Civil Rights Act and  authorized U.S. entry into the Vietnam War. The mid- to late 1960s were  marked by widespread civil disorder, including race riots and antiwar  demonstrations. The U.S. accomplished the first manned lunar landing in  1969. All U.S. troops were withdrawn from Vietnam in 1973. With the  dissolution of the Soviet Union in 1991, the U.S. assumed the status of  sole world superpower. The U.S. led a coalition of forces against Iraq in  the First Persian Gulf War (1991). Administration of the Panama Canal  was turned over to Panama in 1999. After the September 11 attacks on the  U.S. in 2001 destroyed the World Trade Center and part of the Pentagon,  the U.S. attacked Afghanistan�s Taliban government for harbouring and  refusing to extradite the mastermind of the terrorism, Osama bin Laden. In  2003 the U.S. attacked Iraq, with British support, and overthrew the gov�  ernment of Saddam Hussein (see Second Persian Gulf War).

It also provides air services in coordination  with the other military branches. U.S. military activities in the air began  with army use of balloons for reconnaissance during the Civil War and  the Spanish-American War; in 1907 the Aeronautical Division of the Sig�  nal Corps was created. In 1920 the Army Reorganization Act created the  Air Service (after 1926, Air Corps) as a unit of the Army; in 1941 it  became the Army Air Forces. In 1947 the independent U.S. Air Force was  created and became part of the newly created Department of Defense in</p><p>The Department of the Air Force is headquartered at the Pentagon.  Separate operating agencies of the Air Force include the Air Force  Reserve, the Air Force Intelligence Service, and the U.S. Air Force Acad�  emy. In 2000 there were over 350,000 Air Force personnel on active duty.</p><p>United States Air Force Academy Institution for the training of  commissioned officers for the U.S. Air Force, located in Colorado Springs,  Colorado. Created by an act of Congress in 1954, it opened in 1955. Gradu�  ates receive a bachelor�s degree and a second lieutenant�s commission.  Most physically qualified graduates go on to Air Force pilot-training  schools. Candidates may come from the ranks of the U.S. Army or Air  Force, may be children of deceased veterans of the armed forces, or may be  nominated by U.S. senators or representatives or by the president or vice  president. All applicants must take a competitive entrance examination.</p><p>United States Army Major branch of the U.S. military forces, charged  with preserving peace and security and defending the nation. The first  regular U.S. fighting force, the Continental Army, was organized by the  Continental Congress on June 14, 1775, to supplement local militias in the  American Revolution. It was placed under the control of a five-member  civilian board, and U.S. military forces have remained in civilian control  ever since. The U.S. Constitution named the president as commander in  chief, and in 1789 the civilian Department of War was established to  administer the armed forces. The Continental Army was officially dis�  banded in 1783, and a small regular army was established. Thereafter, the  army�s size increased during times of crisis, swelled by conscription, and  decreased during peacetime. The Department of the Army is organized as  a military section of the Department of Defense and is headed by the Sec�  retary of the Army. The Army Staff gives advice and assistance to the  secretary and administers civil functions, including the civil-works pro�  gram of the Corps of Engineers. The army also administers the U.S. Mili�  tary Academy at West Point. In 2000 there were about 400,000 soldiers on  active duty.</p><p>United States Coast Guard U.S. military service that enforces mari�  time laws. It is under the jurisdiction of the Department of Homeland  Security; in wartime it functions as part of the U.S. Navy. The Coast Guard  enforces federal laws on the high seas and waters within U.S. territorial  jurisdiction, develops and operates aids to navigation, and maintains a  network of lifeboat and search-and-rescue stations using surface vessels  and aircraft. It assists in the interdiction of illegal narcotics bound for the  U.S. on or over coastal waters. It operates the International Ice Patrol  (which maintains surveillance of icebergs in the North Atlantic shipping  lanes), gathers data for the National Weather Service, and assists dis�  tressed ships and planes. Its wartime duties include ship escort, port secu�  rity, and transport duty. In 2000 there were some 35,000 Coast Guard  personnel on active duty. Cadets are trained at the Coast Guard Academy  in New London, Conn.</p><p>United States Courts of Appeals In the U.S., the intermediate  appellate courts included in the federal judicial system and created by act  of Congress. There are 13 courts of appeal, including 12 courts whose  jurisdictions are geographically apportioned, and the U.S. Court of  Appeals for the Federal Circuit, whose jurisdiction is subject-oriented and  nationwide. The Federal Circuit court, located in Washington, D.C., was  created by an act of Congress in 1982 and hears appeals from U.S. dis�  trict and territorial courts primarily in patent and trademark cases, though  it also hears appeals in cases in which the United States or its agencies is  a defendant, as in alleged breaches of contract or in tax disputes. The  courts are empowered to review the decisions of federal district courts  (see United States District Court), as well as the decisions of the divisions  of the U.S. Tax Court within their jurisdictions and those of the U.S.  Bankruptcy Courts. All decisions of the courts are subject to review by  the Supreme Court of the United States.</p><p>United States District Court In the U.S., any of the 94 trial courts  of general jurisdiction in the federal judicial system. Each state, as well  as the District of Columbia and the Commonwealth of Puerto Rico, has  at least one federal district court. Each court has at least one district judge  and can have more than a score of them, as well as a clerk, a U.S. attor�  ney, a U.S. marshal, one or more U.S. magistrates, bankruptcy judges,  probation officers, and other staff. Decisions of the district courts are nor�  mally subject to appeal, typically to the United States Court of Appeals for  the region in which the district court is located.</p><p>United States Marine Corps (USMC) Separate military service  within the U.S. Department of the Navy (see U.S. Navy), charged with</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1970</p><p>Strait of  Juan de Fuca</p><p>, Vancouver</p><p>ctoria *</p><p>PortAngeles. -MounfVernon</p><p>OLYMPIC .Everett</p><p>Bremerton* Rooseu</p><p>Aberdeen* * Grand Coul</p><p>OlvmDia� Tacoma Da  Cape U � P 3 1� Rainier r~ SDokan ,'  Disappointmentj^^stor^a - 14,410ft. � Mo ^� ke</p><p>Winnipeg*</p><p>Ygkima,</p><p>Lake ,  of the &amp;  Woodsp</p><p>Portland<emphasis>' -- WA ��</emphasis> ClarkstonUuwtSi^ ,  Salemr^v..

It is also responsible for providing detachments for service  aboard certain types of naval vessels, as well as security forces for naval  shore installations and U.S. diplomatic missions in foreign countries. The  corps specializes in amphibious landings, such as those on Japanese-held  islands in World War II. Marines have served in every major U.S. naval  action since 1775, usually being the first or among the first to fight. In  2000 there were some 175,000 Marines on active duty.</p><p>United States Military Academy known as West Point Institu�  tion for the training of commissioned officers for the U.S. Army. Founded  in 1802 at the fort at West Point, N.Y., it is one of the oldest service acad�  emies in the world. It was established as an apprentice school for mili�  tary engineers and was, in effect, the first U.S. school of engineering. It  was reorganized in 1812, and in 1866 its educational program was  expanded considerably. Women were first admitted in 1976. The four-year  course of college-level education and training leads to a bachelor of sci�  ence degree and a commission as second lieutenant in the Army. West  Point has trained such leaders as Ulysses S. Grant, William T. Sherman,  Robert E. Lee, Stonewall Jackson, Jefferson Davis, John Pershing, Dwight D.  Eisenhower, Douglas MacArthur, Omar Bradley, and George Patton.</p><p>United States Naval Academy known as Annapolis Institution  for the training of commissioned officers for the U.S. Navy and U.S.  Marine Corps. It was founded at Annapolis, Md., in 1845 and reorganized  in 1850-51. Women were first admitted in 1976. Graduates are awarded  the degree of bachelor of science and a commission as ensign in the Navy  or as second lieutenant in the Marine Corps. Annapolis has produced  many notable Americans, including George Dewey, Richard E. Byrd, Ches�  ter Nimitz, William F. Halsey, Jr., A.A. Michelson, Hyman Rickover, Jimmy  Carter, Ross Perot, and several astronauts.</p><p>United States Navy Major branch of the U.S. military forces, charged  with defending the nation at sea and maintaining security on the seas wher�  ever U.S. interests extend. The Continental Navy was established by the  Continental Congress in 1775. It was disbanded in 1784, but the harass�  ment of U.S. merchant ships by Barbary pirates prompted Congress to  establish the Department of the Navy in 1798. The navy took part in the  War of 181 2 and was later important in the Union victory in the American  Civil War. Sea victories during the Spanish-American War (1898) led to a  period of steady growth. In World War I, its duties were limited to troop  transport, minelaying, and escorting merchant ships. The Japanese attack  on the naval base at Pearl Harbor (1941) led to U.S. entry into World War  II, in which, in addition to antisubmarine and troop transport duties, the  navy conducted amphibious assaults in the Pacific theater and along the  European coast. Aircraft carriers proved decisive in battles with Japanese  forces in the Pacific, and they are still the backbone of the navy�s fleets.  Since World War II it has remained the largest and most powerful navy in  the world. The Department of the Navy, a branch of the Department of  Defense, is headed by a secretary of the navy. The navy includes the U.S.  Marine Corps and, during wartime, the U.S. Coast Guard. In 2000 there  were almost 400,000 Navy personnel on active duty, excluding the Marine  Corps and Coast Guard. See also U.S. Naval Academy.</p><p>United States Steel Corp. Leading U.S. producer of steel and related  products. It was founded in 1901 by Charles M. Schwab, Elbert H. Gary,  and J.P. Morgan to consolidate Andrew Carnegie�s Carnegie Steel Co.,  Gary�s Federal Steel Co., and other steel and metal companies. As chair�  man of the board, Gary dominated the corporation in its early years, orga�  nizing price agreements among steel producers and opposing unions. An  antitrust suit against U.S. Steel went as far as the Supreme Court, which  ruled in 1920 that it was not a monopoly in restraint of trade. The corpo�  ration recognized the United Steelworkers of America in 1936. The largest  U.S. steel producer, U.S. Steel diversified into oil and gas in the later 20th  century as well as into chemicals, mining, construction, and transporta�  tion. In 1986 the holding company USX Corp. was established to oversee  it and other operating units. U.S. Steel Group was spun off from USX in  2002 and again became an independent, publicly traded corporation.</p><p>United Steelworkers (USW) historic labour union representing  workers in steel, aluminum, and other metallurgical industries for much  of the 20th century. In the U.S. it grew out of the Steel Workers Orga�  nizing Committee (SWOC), established jointly in 1936 by the Commit�  tee for Industrial Organization (see AFL-CIO) and the Amalgamated  Association of Iron, Steel, and Tin Workers. Under Philip Murray it devel�</p><p>oped into a powerful union. In 1942 SWOC became the United Steel�  workers of America (USWA), of which Murray served as president until  his death in 1952. The USWA absorbed the Aluminum Workers of  America in 1944 and by the mid-1950s had more than one million mem�  bers. It won unprecedented benefits in the postwar period but saw its  membership and power decline as the U.S. steel industry shrank from the  1970s onward. In 2005 the USWA combined with the Paper, Allied-  Industrial, Chemical and Energy Workers International Union (PACE) and  was renamed the United Steel, Paper and Forestry, Rubber, Manufactur�  ing, Energy, Allied Industrial and Service Workers International Union  (USW). The USW represents workers in the United States and Canada.</p><p>Unity (School of Christianity) Religious movement founded in  1889 by Charles Fillmore (1854-1948) and his wife, Myrtle Fillmore  (1845-1931), in Kansas City, Mo., U.S. Believing that spiritual healing  had cured Myrtle of tuberculosis, the couple began to endorse spiritual  healing. Until 1922, Unity was a member of the International New  Thought Alliance. Unlike some New Thought groups, Unity embraces  practical Christianity and modem medicine. It has no definite creed and is  interdenominational. Its Silent Unity service helps people through coun�  seling and prayer, responding to 2.5 million requests for aid a year via  mail, telephone, and Internet. Unity publishes magazines and books, and  it conducts classes for prospective Unity ministers.</p><p>unity-of-science view See unified science</p><p>universal In metaphysics, epistemology, and logic, a general category, such  as a property or relation, considered as distinct from the particular things  that instantiate or exemplify it. The problem of universals concerns the  question of what sort of being should be ascribed to such categories (e.g.,  is there any such thing as redness apart from particular red things?). The  debate over the status of universals stems from Plato�s theory of forms.  Whereas Plato held that forms (universals) exist independently of particu�  lars, Aristotle argued that forms exist only in the particulars in which they  are exemplified. See also realism.</p><p>Universal Declaration of Human Rights Declaration adopted by  the United Nations General Assembly in 1948. Drafted by a committee  chaired by Eleanor Roosevelt, it was adopted without dissent but with eight  abstentions. Among its 30 articles are definitions of civil and political  rights (including the rights to life, liberty, and a fair trial) as well as defi�  nitions of economic, social, and cultural rights (including the right to  social security and to participation in the cultural life of one�s commu�  nity), all of which are owed by UN member states to those under their  jurisdiction. It has acquired more juridical status than originally intended  and has been widely used, even by national courts, as a means of judg�  ing compliance with member states� human-rights obligations. The dec�  laration has been the foundation of the work of nongovernmental  ORGANIZATIONS SUCh as AMNESTY INTERNATIONAL.</p><p>Universal Negro Improvement Association (UNIA) Organi�  zation founded by Marcus Garvey in 1914. Organized in Jamaica, it was  influential in urban African American neighbourhoods in the U.S. after  Garvey�s arrival in New York City in 1916. It was dedicated to racial pride,  economic self-sufficiency, and the formation of an independent black  nation in Africa. After Garvey�s 1923 conviction on charges of fraud, the  UNIA lost influence, but it proved to be a forerunner of black nationalism.</p><p>Universal Pictures U.S. film studio. Formed by Carl Laemmle in 1912,  it became a top producer of popular, low-budget serials in the 1920s and  of horror movies in the 1930s. Its later films include the Abbott and Cos�  tello comedies and the Doris Day-Rock Hudson bedroom farces. The stu�  dio was bought by MCA in 1962, and in 1966 it became a division of  Universal City Studios (now simply Universal Studios), the largest pack�  ager of television series.</p><p>Universal Product Code (UPC) Standard bar code used to identify  grocery and other retail merchandise. In the UPC system, the five digits  on the left are assigned to a particular manufacturer or maker and the five  digits on the right are used by that manufacturer to identify a specific type  or make of product.</p><p>Universal Resource Locator See URL  Universal Serial Bus See USB</p><p>Universal Time Mean (solar) time of the Greenwich meridian (0� lon�  gitude). Universal Time replaced the designation Greenwich Mean Time in  1928; since 1972 it has been based on international atomic time, a uni-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Universalism &#x25BA; Ur I 1973</p><p>form time derived from the frequences of certain atomic transitions and  measured by an atomic clock. For most purposes, it is now identical to  Greenwich Mean Time.</p><p>Universalism Belief in the salvation of all souls. Arising as early as  the time of Origen and at various points in Christian history, the concept  became an organized movement in North America in the mid-18th cen�  tury. It maintains the impossibility that a loving God would bestow sal�  vation on only a portion of humankind while dooming the rest to eternal  punishment. It stresses the use of reason in religion and the modification  of belief in light of the discoveries of science. Thus, the miraculous ele�  ments of traditional Christianity are rejected, and Jesus, while a worthy  teacher and model, is not held to be divine. Universalist and Unitarian  churches in the U.S. merged in 1961 (see Unitarianism).</p><p>universe Whole cosmic system of matter and energy of which Earth is  a part. Its main constituents are the galaxies, within which are stars and  stellar groupings and nebulae (see nebula). Earth�s Sun is one star among  the billions of stars in the Milky Way Galaxy. All atoms, subatomic par�  ticles, and everything they compose are also part of the universe. The uni�  verse is governed by four fundamental forces: the strong force, the weak  force, the electromagnetic force, and gravitation. Numerous theories have  been proposed for the origin and structure of the universe. See also big  bang; cosmology; expanding universe; steady-state theory.</p><p>university Institution of higher education, usually comprising a liberal  arts and sciences college and graduate and professional schools that con�  fer degrees in various fields. A university differs from a college in that it  is usually larger, has a broader curriculum, and offers advanced degrees  in addition to undergraduate degrees. The first true university was the  University of Bologna, founded in the 11th century; the first in northern  Europe was the University of Paris, which served as a model for the uni�  versities of Oxford, Cambridge, Heidelberg, and others. One of the first  modern universities, in which secular objectivity and rationalism replaced  religious orthodoxy, was the University of Halle (founded 1694 in Halle,  Ger.). The liberalism of Halle was adopted by Gottingen, Berlin, and many  other German universities. The German model of the university as a com�  plex of schools and research institutes also exerted a worldwide influ�  ence. The growth of universities in the U.S., where most colleges had been  established by religious denominations, was greatly spurred by the Mor�  rill Act of 1862.</p><p>UNIX Vyii -niks\ Operating system for digital computers, developed by Ken  Thompson of Bell Laboratories in 1969. It was initially designed for a  single user (the name was a pun on the earlier operating system Multics).  The C language was subsequently developed specifically for UNIX, and  the system was rewritten almost entirely in C; it was improved by the  addition of multiprogramming and time-sharing capabilities and enhanced  portability. UNIX is very popular in universities, where it is used mostly  on scientific and engineering workstations, and it is used on most of the  servers of Internet service providers. Because its modular construction  allows it to be easily modified, it has been improved in many ways by  academic and industrial institutions (see Linux).</p><p>Unkei Vun-,ka\ (b. 1148?�d. 1223) Japanese sculptor. He established a  style of realistic and dynamic Buddhist sculpture that had an immense  impact on Japanese art for centuries. Commissioned by the Kamakura sho-  gunate, he made statues for the Kofuku and Todai temples in Nara and is  best remembered for the nearly 26-ft (8-m) tall guardian figures at Todai  temple�s Great South Gate. He later produced many portrait sculptures.</p><p>Unkiar Skelessi, Treaty of See Treaty of Hunkar Lkelesi</p><p>Unser, Bobby and Al in full Robert William Unser and Alfred  Unser (respectively b. Feb. 20, 1934, Albuquerque, N.M., U.S.; b. May  29, 1939, Albuquerque, N.M., U.S.) U.S. automobile-racing drivers. The  Unser brothers were born into a family of drivers and began driving at  an early age. Both won the Pikes Peak hill climb and various U.S. Auto�  mobile Club races before competing in the Indianapolis 500, which Bobby  won in 1968, 1975, and 1981, and Al in 1970, 1971, 1978, and 1987. Al�s  son Al Unser, Jr. (b. 1962), won the same race in 1992 and 1994.</p><p>Unterwalden Yiin-tor-.val-donX Former canton, central Switzerland. It  was ruled after 1173 by the Habsburg counts. In 1291, with Uri and  Schwyz, it formed the Everlasting League, which became the nucleus of  the Swiss Confederation. In 1340 it divided into two sovereign half can�  tons, Nidwalden and Obwalden; in 1803 they became demicantons hav�  ing equal rights.</p><p>untouchable Former classification of various low-status persons and  those outside the Hindu caste system in Indian society. The term Dalit is  now used for such people (in preference to Mohandas K. Gandhi�s term,  Harijan, which was considered condescending by the Dalit themselves),  and their plight is recognized by the Indian constitution and by legisla�  tion. The groups traditionally considered untouchable included people  whose occupations or habits of life involved activities considered to be  polluting, such as taking life for a living (e.g., fishermen); killing or dis�  posing of dead cattle or working with their hides; coming into contact  with human waste (e.g., sweepers); and eating flesh of cattle, pigs, or  chickens. Many untouchables converted to other religions to escape dis�  crimination. Indian law now categorizes the Dalit under the term sched�  uled castes and accords them certain special privileges.</p><p>upanayana V.u-po-'no-yo-noX Hindu initiation ritual, restricted to the  three upper varnas. It marks a male�s entrance into the life of a student  and his acceptance as a full member of the religious community. After a  ritual bath, the boy, aged 5-24, is dressed as an ascetic and brought before  his guru, who invests him with various symbolic articles. The initiate  receives a sacred thread, worn throughout his life, that identifies him as  twice-born, the second birth being effected by receipt of a mantra. Obser�  vance of upanayana is decreasing and is now largely confined to the Brah�  man class.</p><p>Upanishad \u-'pa-ni-,shad\ Any of 108 speculative texts of the Vedas  that contain elaborations in poetry and verse. They are believed to have  been composed since 500 bc, based on teachings circulated since 1000 bc.  They represent the final stage in the tradition of the Vedas, and the teach�  ing based on them is called Vedanta. Generally the Upanishads are con�  cerned with the nature of reality, the individual soul (atman), and the  universal soul (Brahman) and with the theory of the transmigration of souls  and the nature of morality.</p><p>upasaka Ui-'pa-so-koV Lay devotee of the Buddha. Originally the term  applied to followers of the Buddha who were not ordained as bhiksus; today  it is normally applied, mainly in Southeast Asia, to pious individuals who  visit the local monastery on the weekly holy days and who undertake spe�  cial vows. They support the sangha with regular offerings and observe the  five precepts expected of all Buddhists: to abstain from killing, stealing,  sexual misconduct, lying, and using intoxicants.</p><p>UPC See Universal Product Code</p><p>Updike, John (Hoyer) (b. March 18, 1932, Shillington, Pa., U.S.)  U.S. writer. He attended Harvard University and in 1955 began a long  association with The New Yorker. His works are known for careful crafts�  manship and for their subtle depiction of American middle-class life. His  famous �Rabbit� tetralogy� Rabbit, Run (1960), Rabbit Redux (1971),  Rabbit Is Rich (1981, Pulitzer Prize), and Rabbit at Rest (1990, Pulitzer  Prize)�follows a very ordinary American man through the decades of  the later 20th century. A Jewish novelist named Bech is the subject of  three other novels. Updike�s other fiction includes The Centaur (1963),  Of the Farm (1965), Couples (1968), The Witches ofEastwick{ 1984; film,  1987), and In the Beauty of the Lilies (1996). He has also published short-  story collections, including Pigeon Feathers (1962), several volumes of  reviews and essays, and light verse.</p><p>Upper Canada See Canada West  Upper Volta See Burkina Faso</p><p>Uppsala \ , up-,sa- l la\ City (pop., 2001 est.: 191,110), Sweden. Located  north of Stockholm, it lies near a village which was originally the capital  of the ancient pre-Christian kingdom of Svea. By the 13th century it was  an important commercial centre. Relinquishing its political primacy to  Stockholm, it remained the seat of the archbishop of Sweden; its Gothic  cathedral (erected from the 13th�15th centuries) is Sweden�s largest. It is  also an educational centre, the site of Sweden�s oldest university, Upp�  sala University (founded 1477). It is now an industrial city and transpor�  tation hub.

Generally held to constitute the boundary between Europe and Asia, the  range extends north-south for some 1,550 mi (2,500 km) from just south  of the Kara Sea to the Ural River. The mountains average 3,000^4,000 ft  (915-1,220 m) in elevation; the highest peak is Mount Narodnaya at 6,217  ft (1,895 m). The Central and Southern Urals contain one of the largest  industrial regions of Russia, producing metal goods, chemicals, and  machinery; that region developed rapidly during World War II (1939-45),  when many industrial plants were moved from the western part of the  Soviet Union to prevent their destruction by the Germans.</p><p>Ural River River, Russia and Kazakhstan. Rising at the southern end  of the Ural Mountains, it flows southwest to cross through western Kaza�  khstan to the Caspian Sea at Atyrau.

Its lower course is navi�  gable.</p><p>Uralic \yu-'ra-lik\ languages Family of more than 30 languages spo�  ken by some 25 million people in central and northern Eurasia. A primary  division is between the Finno-Ugric languages, which account for most of  the languages and speakers, and the Samoyedic languages. The latter lan�  guages have historically been spoken in the forest region of northern  Siberia and in the tundra and coastal zones from the Ob to the White Sea  and east into the Taymyr Peninsula. The known languages are Nganasan,  Enets, Nenets, Selkup, Kamas (which became extinct in the late 20th cen�  tury), and Mator (which became extinct in the 19th century). Of the other  languages that are still spoken,</p><p>Nenets, which has 25,000 speakers  and is still being learned by children,  is the most viable. The Samoyedic  languages share little vocabulary  with Finno-Ugric. At its very earliest  stages Uralic most probably included  the ancestors of the Yukaghir lan�  guages, still sometimes included  with the Paleo-Siberian languages.</p><p>uraninite Vyu-'ra-no-.nltV Uranium  dioxide (U0 2 ), a major oxide mineral  of uranium.

See also pitchblende.</p><p>uranium Chemical element of the actinide series (with many transition  element properties), chemical symbol U, atomic number 92. A dense, hard,  silvery white metal that tarnishes in air, it is isolated from such ores as  pitchblende. Until the discovery of the first transuranium element in 1940,  uranium was believed to be the heaviest element. Radioactivity was dis�  covered in uranium by A.-H. Becquerel. All its isotopes are radioactive;  several have half-lives long enough to permit determination of the age of  the Earth by uranium-thorium-lead dating and uranium-234-uranium-238  dating. Nuclear fission was discovered in 1938 in uranium bombarded with  neutrons, and the self-sustaining nuclear chain reaction, the atomic bomb,  and the generation of nuclear power followed. Uranium has various  valences in compounds, some of which have been used as colours in  ceramic glazes, in lightbulb filaments, in photography, and as dyes and  mordants.</p><p>uranium-234-uranium-238 dating Method of age determina�  tion that makes use of the radioactive decay of uranium-238 to uranium-  234; the method can be used for dating sediments from either a marine  or a playa lake environment. Because this method is useful for the period  c. 100,000-1.2 million years before the present, it helps in bridging the  gap between the carbon- 14 dating method and the potassium-argon dat�  ing method.</p><p>uranium-thorium-lead dating or common-lead dating</p><p>Method of dating very old rocks by means of the amount of common lead  they contain. Common lead is any lead from a rock or mineral that con�  tains a large amount of lead and a small amount of the radioactive pre�  cursors of lead (i.e., the isotopes uranium-235, uranium-238, and thorium-  232). By this method, the age of the Earth has been estimated to be c. 4.6  billion years. This figure is in good agreement with the age of meteorites  and the age of the Moon as determined independently.</p><p>Uranus or Ouranus Vyur-s-nos, yu-'ra-nosN Ancient Greek personifi�  cation of heaven. When Gaea emerged from Chaos, she produced Uranus,  the mountains, and the sea. Her subsequent union with Uranus produced  the Titans, the Cyclopes, and the Hecatoncheires. Uranus despised his off�  spring and hid them in Gaea�s body. In response to her appeal for ven�  geance, Cronus castrated Uranus. From the drops of blood that fell on  Earth were born the Furies, the Giants, and the ash-tree nymphs called  Meliai. His severed genitals floated on the sea, producing a white foam  from which sprang Aphrodite. Uranus also consorted with Clymene, Hem-  era, Hestia, and Nyx.</p><p>Uranus Seventh planet from the Sun. It was discovered in 1781 by Wil�  liam Herschel (see Herschel family) and named for the Greek god personi�  fying heaven. A blue-green gas giant, it has almost 15 times the mass of  Earth and over 50 times its volume. It is less dense than Earth; the grav�  ity at the top of its atmosphere is 11 % weaker. Its equatorial diameter is  31,800 mi (51,100 km). Uranus has 10 sharply defined narrow, dark rings,  with broad dust bands between them; the rings consist mainly of boulder-  size chunks of dark material. Uranus also has at least 27 moons (most  named after Shakespearean characters) and a magnetic field about as  strong as Earth�s. The planet rotates once every 17 hours around an axis  that, unusually, is almost parallel to the ecliptic; from Earth it appears to  spin on its side. It takes 84 years to orbit the Sun, at a mean distance of  1.78 billion mi (2.87 billion km). It has no solid surface; its fluid interior  is thought to consist of a mixture of rock, ices, and gas, with little or no  rocky core. Its upper atmosphere is mostly hydrogen and helium; the  blue-green colour comes from absorption of red light by the small amount  of methane present.</p><p>Urartu \u-'rar-,tu\ Ancient kingdom around Lake Van, southwestern  Asia. Today the region is divided among Armenia, eastern Turkey, and  northwestern Iran. The kingdom flourished c. 13th�7th century bc, enjoy�  ing considerable power in the Middle East in the 9th-8th century.  Archaeological finds date from the time of King Shalmaneser I (c. 1274-  45) of Assyria. Repeatedly attacked by Assyrian kings, Urartu declined  in the late 8th century. It ceased to exist after invasions by Cimmerians,  Scythians, and Medes in the 7th century bc.</p><p>Urban II orig.

Elected pope  in 1088, Urban secured his authority against the antipope Clement 111 and  strengthened the role of the papacy in the reform movement. He called  for the First Crusade at the Council of Clermont (1095) in response to the  appeal of Alexius I Comnenus, promoted the union of the Eastern and  Western churches, and supported the Christian reconquest of Spain from  the Moors.</p><p>Urban VI orig. Bartolomeo Prignano (b. 1318, Naples�d. Oct.  15, 1289, Rome) Pope (1378-89). Archbishop of Acerenza (1363) and  Bari (1377), he became papal chancellor for Gregory XI, whom he was  chosen to succeed. This election of an Italian appeased the Romans, who  wanted to end the French-dominated Avignon papacy, but his harsh  reforms soon angered the French cardinals, prompting them to elect the  antipope Clement VII, beginning the Western Schism (1378). Europe was  divided in its loyalties, and Urban warred with Naples when its queen  backed Clement. Strife over the schism reduced the Papal States to anar�  chy, and Urban�s death may have been from poisoning.</p><p>urban climate Any set of climatic conditions that prevails in a large  metropolitan area and that differs from the climate of its rural surround�  ings. Urban climates are distinguished from those of less built-up areas  by differences of air temperature, humidity, wind speed and direction, and  amount of precipitation. These differences are attributable in large part to  the altering of the natural terrain through the construction of artificial  structures and surfaces. For example, tall buildings, paved streets, and  parking lots affect wind flow, precipitation runoff, and the local energy  balance.</p><p>urban planning Programs pursued as a means of improving the urban  environment and achieving certain social and economic objectives. Evi�  dence of urban planning can be found in the ruins of ancient cities, includ�  ing orderly street systems and conduits for water and sewage. During the  Renaissance, European city areas were consciously planned to achieve  circulation of the populace and provide fortification against invasion.  Such concepts were exported to the New World, where William Penn, in  founding the city of Philadelphia, developed the standard gridiron plan�  the laying out of streets and plots of land adaptable to rapid change in  land use. Modem urban planning and redevelopment arose in response to  the disorder and squalor of the slums created by the Industrial Revolution.  The urban planner best known for his transformation of Paris was  Georges-Eugene Haussmann. City planners imposed regulatory laws estab�  lishing standards for housing, sanitation, water supply, sewage, and pub�  lic health conditions, and introduced parks and playgrounds into  congested city neighbourhoods. In the 20th century, zoning�the regula�  tion of building activity according to use and location�came to be a key  tool for city planners.

Early wares,  mostly dishes, are painted in a range of colours, dominated by brilliant  yellow, orange, and brown, and decorated with narrative scenes typically  covering the entire surface, a style known as istoriato. Scenes are taken  from the Bible, mythology. Classical and contemporary history, and  poetry. Later wares were decorated in a style called grotesque, adapted  from motifs found in Roman excavations. Production declined in the late  17th century. See also majolica.</p><p>Urdu \'ur-du\ language Indo-Aryan language used by Muslims in  India and Pakistan. In the sociopolitical realm, Urdu and Hindi are differ�  ent languages, but the colloquial basis of both is identical, and as a writ�  ten language Urdu differs from Hindi principally in its greater acceptance  of Persian-Arabic vocabulary and in some syntactic features. It is written  in the Arabic alphabet with modification of some letters to denote specifi�  cally Indo-Aryan sounds. As Pakistan�s official language, Urdu has been  promoted as a token of national unity, though less than 8% of Pakistanis�  mainly immigrants and descendants of immigrants from India after the  1947 partition�speak it as a first language.</p><p>urea \yu-'re-o\ or carbamide One of the simplest organic compounds  and the first synthesized from inorganic raw materials (see inorganic com�  pound), by Friedrich Wohler (1800-82) in 1828. It is the diamide of car�  bonic acid (H 2 NCONH 2 ; see amide; carbon dioxide). The chief nitrogenous  end product of protein breakdown in mammals and some fishes, it occurs  not only in urine but also in blood, bile, milk, and perspiration. It is one of  the industrial chemicals produced in vast amounts. With its high nitrogen  content and low price, it is a major agricultural fertilizer and animal-feed</p><p>ingredient. It is also used to make urea-formaldehyde plastics (including  foamed plastics; see polyurethanes), to synthesize barbiturates, as a stabi�  lizer in explosives, and in adhesives, hydrocarbon processing, and flame�  proofing.</p><p>uremia \yu-'re-me-3\ Excess nitrogenous waste products in the blood  and their toxic effects. Kidney impairment (see Bright disease; diabetes mel-  utus; hypertension; kidney failure; nephritis) or disorders that hinder urine  excretion (e.g., prostatic disorders) allow urea and other protein waste  products to accumulate. Symptoms usually start with fatigue and loss of  concentration. They may include itching and muscle twitches; dry, flaky,  yellowish skin; dry mouth, metallic taste, and ammonia breath; and nau�  sea, vomiting, diarrhea, and constipation. Advanced stages affect the ner�  vous, cardiovascular, and respiratory systems and can lead to  hypertension, seizures, heart failure, and death. If the underlying disorder  cannot be treated, dialysis or kidney transplant may be required.</p><p>Urey \'yur-e\, Harold C(layton) (b. April 29, 1893, Walkerton, Ind.,  U.S.�d.

He was awarded a Nobel Prize in 1934 for  discovering deuterium and heavy water. He was a key figure in the devel�  opment of the atomic bomb; his group worked on the gaseous diffusion pro�  cess for separation of uranium-235. He devised methods for estimating  the temperature of ancient oceans, theorized on the compositions of pri�  mordial atmospheres, and studied the relative abundances of the elements,  making fundamental contributions to a widely accepted theory of the ori�  gin of the Earth and other planets in The Planets, (1952).</p><p>Uriburu \ l ii-re- , bu-rU\ / Jose Felix (b.

A visit to Ger�  many made him an ardent admirer of Prussian militarism. In 1930 he led  a coup against Hipolito Irigoyen�s liberal regime, replacing the governing  class with an elite representing the landed oligarchy, dissolving the leg�  islature, and revising the laws to prohibit liberal-radicals from political  participation. In 1931 he arranged a fraudulent election to ensure the oli�  garchy�s continued control and stepped down in favour of a fellow officer,  Agustrn Justo.</p><p>uric acid Vyur-ik\ Heterocyclic compound of the purine type, the end  product of metabolism of the purines in nucleic acids in many animals,  including humans. It is excreted by reptiles and birds as the chief nitrog�  enous end product of protein breakdown. Small quantities are normally  found in human blood; in gout, levels are abnormally high. Uric acid is  used industrially in organic synthesis.</p><p>urinalysis \ l yur-3- , na-lo-s9s\ Laboratory examination of a urine sample  for clinical information. Abnormal concentrations of substances normally  found in urine or presence of those that are not may indicate a disorder.  Colour, specific gravity, or volume changes may reveal a specific disease  or injury. Significant findings include high glucose and acetone in diabe�  tes mellitus; various nitrogen compounds, pigments, amino acids, and their  metabolic products in disorders of the enzymes that act on them; uric acid  in gout; and urea, albumins, and globulins in kidney disease. Hormones  may be evidence of pregnancy or endocrine imbalance. Urinalysis can  also detect poisons and drugs.</p><p>urinary system or renal \'re-nol\ system System that produces and  discharges urine to rid the body of waste products. It consists of the kid�  neys, which balance electrolytes in blood, retaining and adding needed  ones and removing unneeded or dangerous ones for excretion; the ureters,  two thin muscular tubes 10-12 in. (25-30 cm) long that move the urine  by peristalsis; the hollow, muscular bladder, which receives and stores it;  and the urethra, through which it leaves the body. In women the urethra  is 1.5 in. (4 cm) long. In men it is longer (since it passes through the  penis), about 8 in. (20 cm), and carries semen from the prostate gland as  well as urine. Urinary disorders, which can lead to dehydration or edema  and to a dangerous buildup of waste and toxic substances, include kidney  failure, tumours, and bladder and kidney stones.</p><p>urination Process of excreting urine from the bladder (see urinary sys�  tem). Nerve centres in the spinal cord, brain stem, and cerebral cortex  control it through involuntary and voluntary muscles. The need to void  is felt when the bladder holds 3.5-5 oz (100-150 ml) of urine and becomes  uncomfortable at a volume of 14-15 oz (350^-00 ml).

It is about 87 mi (140 km) long  and 25-35 mi (40-55 km) wide, with a maximum depth of 53 ft (16 m).  There is a cluster of about 50 tiny islands at its southern part. Fed by three  rivers, it has no outlet. It has been protected since 1967.</p><p>Urnfield culture Late Bronze Age culture of Europe, so called because  its people placed their cremated dead in urns. This culture spread from  east-central Europe and northern Italy in the 12th century bc and later to  Ukraine, Sicily, Scandinavia, France, and Spain. In some areas barrows  marked the graves. The culture was warlike, with fortified settlements and  bronze weapons, including the slashing sword. The uniformity of the cul�  ture and the persistence of certain pottery and metal forms apparently had  great influence on Early Iron Age culture.</p><p>urogenital malformation Defect in the organs or tissues of the uri�  nary system or in the sex organs (genitals). In polycystic kidney disease  (an inherited disease), cysts of varying size enlarge one or both kidneys.  Kidneys may have abnormal shapes or may be fused. In megaloureter, the  ureter�s diameter is enlarged. Males may have epispadias or hypospadias,  in which the urethra opens on the upper surface or the underside, respec�  tively, of the penis, or cryptorchidism (undescended testicles), in which  one or both testes have not descended from the abdomen into the scro�  tum before birth. Female genital system malformations include agenesis  of the ovaries, vagina, or uterus and abnormally shaped uterus.</p><p>urology \yu-'ra-l9-je\ Medical specialty dealing with the urinary system  and male reproductive organs. It traces its origin to medieval lithologists,  itinerant healers who specialized in surgical removal of bladder stones.  The Spanish surgeon Francisco Diaz wrote the first treatises on urinary-  tract disease (1588) and is regarded as the founder of modem urology.  Most modem urological procedures originated in the 19th century. Today,  urologists use bladder catheters (see catheterization), the cystoscope (to  view the inside of the bladder), and various diagnostic imaging techniques;  treat prostatic disorders; perform vasectomies; and may surgically remove  stones in the urinary tract and cancers of the kidneys, bladder, and tes�  ticles. Urology deals mostly with male patients; the urinary tract in  females may be treated by gynecologists (see obstetrics and gynecology).</p><p>Urquiza Vur-'ke-saV, Justo Jose de (b.

Uruguay is the only South American country  lying entirely outside the tropics. Its topography consists mainly of low  plateaus and low hilly regions. The principal waterway is the Negro River;  the Uruguay River forms the country�s entire western border with Argen�  tina. Mineral and energy resources are limited. Pastures, covering almost  four-fifths of the land area, support large herds of livestock raised for  meat, leather goods, and wool. Chief crops include rice, sugarcane,  oranges, wheat, and corn. Other important economic activities are tour�  ism, fishing, and the manufacture of textiles and chemicals. Uruguay is a  republic with two legislative houses; its head of state and government is  the president. Prior to European settlement, it was inhabited mainly by  the Charrua and Guarani Indians. The Spanish navigator Juan Diaz de  Solis sailed into the Rio de la Plata estuary in 1516. The Portuguese  established Colonia in 1680. Subsequently the Spanish established Mon�  tevideo in 1726, driving the Portuguese from their settlement; 50 years  later Uruguay became part of the Viceroyalty of the Rio de la Plata. It  gained independence from Spain in 1811. The Portuguese regained it in  1821, incorporating it into Brazil as a province. A revolt against Brazil in  1825 led to its being recognized as an independent country in 1828. It  sided with Brazil and Argentina against Paraguay in the War of the Triple</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Uruguay River &#x25BA; Utamaro I 1977</p><p>Alliance (1864/65-70).

The office of the president was abolished in 1951 and replaced with a  nine-member council. The country adopted a new constitution and  restored the presidential system in 1966. A military coup occurred in 1973,  but the country returned to civilian rule in 1985.

From its start, U.S. News &amp; World Report had a somewhat more  conservative editorial viewpoint than its larger rivals, Time and Newsweek,  and it paid less attention to sports and the arts. In 1984 it was bought by  real-estate developer Mortimer B. Zuckerman, who later purchased the  New York Daily News.

March 28, 2004, Genolier, Switz.) British actor, direc�  tor, author, and playwright. He made his professional stage debut at age  17, in which he displayed his talents for vocal mimicry and age affecta�  tion, and landed his first major screen role in The Goose Steps Out{ 1942).  His film appearances include Lola Montes (1955), Spartacus (1960, Acad�  emy Award), Topkapi (1964, Academy Award), and a recurring role as  Hercule Poirot in movies based on Agatha Christie�s mysteries, beginning  with Death on the Nile (1978). He both starred in and directed Billy Budd  (1962), among other films. Lady L (1965), with Sophia Loren and Paul  Newman, was probably his best-received directorial effort. He wrote suc�  cessful plays such as The Love of Four Colonels (1951) and Romanoff  and Juliet (1956) and won Emmy Awards for his television performances  in The Life of Samuel Johnson (1957), Barefoot in Athens (1966), and A  Storm in Summer (1970). Ustinov also wrote several novels and the auto�  biographical works Dear Me (1977), Ustinov at Large (1993), and Usti�  nov Still at Large (1994). Noted for his humanitarian efforts, he served  as ambassador at large for UNICEF from 1969 until his death.

Utah is bordered by Idaho  to the north, Wyoming to the northeast, Colorado to the east, Arizona to  the south, and Nevada to the west. At Four Corners, in the southeast, Utah  meets Colorado, New Mexico, and Arizona at right angles, the only such  meeting of states in the nation. Utah contains the Great Salt Lake and parts  of the middle Rocky Mountains and Uinta Mountains. The western third  of the state is a broad desert-like area. About 70% of the land is owned  by either the federal or the state government. The region was inhabited  as early as 10,000 bc. In c. ad 400 the Pueblo Indians lived throughout  Utah; they were followed by other groups, including the Shoshone, Ute,  and Paiute Indians. Spanish missionaries visited there in the late 18th cen�  tury. It passed to Mexico in 1821. U.S. pioneer Jim Bridger was the first  white man to see the Great Salt Lake, in 1824. The area�s first permanent  settlers were Mormons, who were led to the valley of the Great Salt Lake  in 1847 by Brigham Young. Acquired by the U.S. after the Mexican War,  the region was organized as the Utah Territory in 1850; it had been  reduced to the area of the present state by 1868. A conflict between Mor�  mon authorities and the U.S. government known as the Utah War occurred  in 1857-58, and statehood was denied until the Mormons renounced  polygamy. When they did, Utah entered the Union in 1896 as the 45th state.  The Mormon church has officially been politically neutral since the early  20th century, and the influence of economic blocs has become more  important. Utah has large reserves of coal and petroleum and is the  world�s largest producer of beryllium. Major industries include agricul�  ture and tourism.</p><p>Utamaro \u-ta-'ma-ro\ orig.

He moved  from a provincial town to Edo (now Tokyo) in his youth; his early work  included many illustrated books. One of the greatest ukiyo-e artists, he is  known especially for his masterfully composed portraits of sensuous  female beauties.

They eventually joined into a loose con�  federation of seven bands. Until the 19th century, the Ute had no horses  and lived in small family clusters, subsisting by food collecting. They  were virtually indistinguishable from the Southern Paiute. When the Ute  acquired horses in the early 1800s, they became organized as loose bands  of hunters, often targeting livestock. After the Indian wars of 1864-70,  most Ute were settled on reservations. At the turn of the 21st century,  they numbered more than 5,000.</p><p>uterine Yyii-ta-ranV bleeding Abnormal bleeding from the uterus not  related to menstruation. Most common in the first few years after menarche  and as menopause approaches, it is thought to occur when malfunctioning  ovaries reduce blood estrogen levels. A malfunctioning hypothalamus or pitu�  itary gland may also cause hormonally induced uterine bleeding, as can  birth-control pills or hormone-replacement therapy. Some tumours pro�  duce estrogen and can alter the menstrual cycle, causing bleeding. Tumours  in the uterus often bleed easily. Other causes include injury to the uterus,  stress, obesity, chronic illness, psychological problems, and blood and car�  diovascular disorders. Treatment is directed toward the underlying cause.</p><p>uterine cancer Malignant tumour of the uterus. Cancers affecting the  lining of the uterus (endometrium) are the most common cancers of the  female reproductive tract. Risk factors include absence of pregnancy,  early age of first menstruation (before age 12), late onset of menopause  (after age 52), obesity, diabetes, and estrogen replacement therapy. Addi�  tional risk factors are a personal history of breast or ovarian cancer, age  (over age 40), and a family history of uterine cancer. Whites are more  likely to develop uterine cancer than are blacks. The major symptom is  vaginal bleeding or discharge. Treatment may begin with simple or radi�  cal hysterectomy. Some uterine cancers are treated in part by hormonal  therapy, radiation therapy, or chemotherapy.</p><p>uterus or womb Inverted-pear-shaped organ of the female reproduc�  tive system, in which the embryo and fetus develop during pregnancy. Lying  over and behind the bladder, it is 2.5-3 in. (6-8 cm) long and about 2.5  in. (6 cm) across at the top, where the fallopian tubes enter it; at the other  end, the cervix extends down into the vagina. The uterine lining  (endometrium), a moist mucous membrane, changes in thickness during  the menstrual cycle (see menstruation), being thickest at ovulation in readi�  ness for a fertilized EGG. The uterine wall, about 1 in. (2.5 cm) thick,  expands and becomes thinner as a fetus develops inside. The cervix  expands to about 4 in. (10 cm) for delivery. Disorders of the uterus include  infections, benign and malignant tumours, prolapse, endometriosis, and  fibroids (leiomyomas; see muscle tumour).</p><p>'Uthman ibn 'Affan Nuth-'man-.i-bon-af-'fanV (d.

He married a daughter of Muhammad. On the death of 'Umar ibn  al-Khattab (644), �Uthman was chosen as his successor. His reign as caliph  was marked by nepotism and personal profit, and he made many enemies.  His accomplishments included centralizing the administration of the  caliphate and establishing an official version of the Qu�ran.

Consid�  ered the oldest Phoenician settlement, it was located in what is now mod�  ern Tunisia. After its founding (c. 8th century bc), it grew rapidly and was  second in importance only to Carthage. Made the capital of the Roman  province of Africa after the Third Punic War (149-146 bc), it later declined  after the emperor Augustus rebuilt Carthage. Excavations have uncovered  Phoenician graves dating from the 8th century bc and a substantial resi�  dential section of the Roman city.

Thus, utilitarians focus on the consequences of an act  rather than on its intrinsic nature or the motives of the agent (see conse-  quentialism). Classical utilitarianism is hedonist, but values other than, or  in addition to, pleasure (ideal utilitarianism) can be employed, or�more  neutrally, and in a version popular in economics�anything can be  regarded as valuable that appears as an object of rational or informed</p><p>desire (preference utilitarianism). The test of utility maximization can also  be applied directly to single acts (act utilitarianism), or to acts only indi�  rectly through some other suitable object of moral assessment, such as  rules of conduct (rule utilitarianism). Jeremy Bentham�s Introduction to the  Principles of Morals and Legislation (1789) and John Stuart Mill�s Utili�  tarianism (1863) are major statements of utilitarianism.</p><p>Uto-Aztecan X.yii-to-'az-.te-konX languages Family of more than 30  American Indian languages spoken in pre-Columbian times from the  northern Great Basin to Central America.

The site of successive Roman, Frisian, and Frankish for�  tresses, it became an episcopal see in 696 under St. Willibrord. It was  most prosperous during the 11th and 12th centuries, when it was an impor�  tant commercial centre. In 1527 it was transferred to Holy Roman  Emperor Charles V and became part of the Habsburg dominions. It was  ruled by Spain until the 1570s, when it became a centre of Protestant  resistance. It was the site of the signing of the Union of Utrecht (1579),  which established a league of northern Dutch provinces against Spain;  the league was the basis of the future Netherlands kingdom. Occupied by  the French (1795-1813), it was the residence of Louis Bonaparte, king of  Holland (1806-10). The only Dutch pope, Adrian VI, was born in Utre�  cht. It is a transportation, financial, and insurance centre.</p><p>Utrecht, Peace of (1713 -14) Series of treaties concluding the War of  the Spanish Succession. One series was signed between France and other  European powers; another series was signed between Spain and other  powers. France concluded treaties with Britain, the Dutch Republic, Prus�  sia, Portugal, and Savoy, in which it ceded various territories, including  regions in Canada, to Britain. France also recognized Queen Anne as the  British sovereign, acknowledged Frederick I�s royal title, and recognized  Victor Amadeus II as king of Sicily. Spain ceded Gibraltar to Britain. In a  separate accord, the asiento agreement, Spain gave Britain the exclusive  right to supply the Spanish colonies with African slaves for 30 years.  Emperor Charles VI concluded a separate peace with France in the Treaty  of Rastatt and Baden. The Spanish succession was settled in favour of the  Bourbon Philip V. The treaties gave Britain the largest portion of colonial  and commercial spoils and made it the leader in world trade.</p><p>Utrecht school Principally a group of three Dutch painters from  Utrecht �Dirck van Baburen (c. 1590-1624), Gerrit van Honthorst, and  Hendrik Terbrugghen �who were greatly influenced by Caravaggio�s art  during travels to Rome. They used their newly learned technique in art�  work with primarily religious subject matter, but also produced brothel  scenes and pictures in sets, such as five works devoted to the senses. The  numerous candles, lanterns, and other sources of artificial light in their  paintings also differentiate them from Caravaggio, who never used such  devices. Honthorst enjoyed the widest reputation at the time, but Terbrug�  ghen is now considered the most talented and versatile of the group.</p><p>Utrillo \tE-tre-'yo,\ English Xyti-'tri-loV Maurice (b.

He had no formal artistic training and was interested prima�  rily in reproducing what he saw as faithfully as possible. Most of his  compositions depict the old, deteriorating houses and streets of the Mont�  martre district of Paris. His best work is that of his �white period� (c.  1908-14), so called for his lavish use of zinc white in heavy layers to  build up aging, cracked walls.

The state, the most populous in the country, lies largely in the plains  formed by the Ganges and Yamuna rivers. The region was the setting of  two great Sanskrit epics, the Mahabharata and Ramayana, and the scene of  the rise of Buddhism after the 6th century bc. It was ruled by the Mauryan  emperor Ashoka in the mid-3rd century bc, the Gupta dynasty (c. ad 320-c.  415), and King Harsa (606-647). The Mughals gained control in the 16th  century, at which time the city of Agra became a chief centre. The British  arrived in the late 18th century; by the 1830s they held sway and eventu�  ally formed the North-Western Provinces, to which Oudh was later  annexed. The area was the main scene of the Indian Mutiny of 1857. The  current province was formed in 1902 and became a state of India in 1947.  In 2000 the northern portion of it was made into the state of Uttaranchal.  Uttar Pradesh is a major silica-producing state, yet agriculture is its most  important economic sector.

Although it contains fertile  oases and high mountain ranges in the south and east, almost four-fifths  of the country consists of flat, sunbaked lowlands. Two-thirds of the Aral  Sea extends into Uzbekistan. It is a major producer and exporter of natu�  ral gas and has sizable reserves of petroleum, coal, and various metallic  ores. It is a leading grower of cotton and also produces fruits and veg�  etables and Karakul sheep. It is the main manufacturer of machinery and  heavy equipment in Central Asia. It is a republic with one legislative body;  its head of state is the president, and the head of government is the prime  minister. A grandson of Mongol leader Genghis Khan received the terri�  tory as his inheritance in the 13th century. The Mongols ruled over a  number of Turkic tribes, who would eventually intermarry with the Mon�  gols to form the Uzbeks and other Turkic peoples of Central Asia.

The earliest record of the city dates from a charter of ad 812, and during  the succeeding centuries it came under various rulers, including those of  the Muslim Delhi sultanate and the Mughal dynasty. Its varied products  include cotton textiles, chemicals, machinery, and furniture.</p><p>Vaduz \fa-'diits\ City (pop., 1997 est.: 5,000), capital of Liechtenstein.  Located on the Rhine River, it was greatly damaged in 1499 in a war  between the Swiss and Holy Roman Emperor Maximilian I, but it was sub�  sequently rebuilt. The Liechtenstein family gained possession in the early  18th century. It is a flourishing tourist centre and the residence of the rul�  ing prince, whose castle overlooks the town. The town�s Furst Liechten-  steinische Gemaldegalerie displays parts of the world-famous art  collection of the princes of Liechtenstein.</p><p>Vaganova \v9-'ga-n9-v9\, Agrippina (Yakovlevna) (b. July 6,  1879, St. Petersburg, Russia�d. Nov. 5, 1951, Leningrad) Russian ballet  dancer and teacher. In 1897 she joined the Mariinsky Theatre company,  where she worked until 1917. She began teaching  at the Leningrad Choreographic (formerly Imperial  Ballet) school in 1921 and became its director in  1934. Her system of ballet instruction combined clas�  sic technique with the athletic, acrobatic post-  Revolution style. She wrote the widely used textbook  Fundamentals of the Classic Dance (1934).</p><p>vagina \v9-'jl-n9\ Genital canal in females. Together with  the cavity of the uterus, it forms the birth canal. In most vir�  gins, its external opening is partially closed by a thin fold of  tissue (hymen), which has various forms, not all of which sig�  nificantly obstruct the opening. The vagina�s lining thickens and  thins during the menstrual cycle (see menstruation) in response to  estrogen from the ovaries, being thickest and most elastic during  ovulation and pregnancy. Its normally slightly acid environment  discourages disease-causing microorganisms. Thick, elastic muscle  walls accommodate movement of the penis during intercourse and  passage of a child during delivery. A mucuslike fluid seeps through  them for lubrication during sexual arousal. Vaginal disorders include  bacterial and fungal infections (e.g., sexually transmitted diseases, Candida),  vaginitis, sores (see ulcer), and prolapse.</p><p>vaginitis V.va-js-'nI-tssV Inflammation of the vagina. The chief symptom  is a whitish or yellowish vaginal discharge. Treatment depends on the  cause: appropriate drugs for sexually transmitted diseases (often from Gard-  nerella bacteria or trichomonads) or yeast infections; estrogen cream for  atrophy of the vaginal lining, which may dry out after menopause; and  avoidance of any chemicals found to trigger irritation or allergy.</p><p>vagrancy Act of wandering about without employment or identifiable  means of support. Traditionally a vagrant was thought to be one who was  able to work for his maintenance but preferred instead to live idly, often  as a beggar. Punishment ranged from branding and whipping to conscrip�  tion into the military services and transportation to penal colonies. In the  U.S., laws against vagrancy were used by police and prosecutors to pro�  scribe a wide range of behaviours. Many such laws were struck down as  unconstitutionally vague, thus largely decriminalizing vagrancy, though  in the 1990s many local laws were implemented to curtail aggressive  panhandling, begging, and other activities by vagrants on city streets.</p><p>Vah Vvak\ River River, western  Slovakia.

Founded c. 2nd-3rd century ad, it fused with  Nyaya in the 11th century, forming the Nyaya-Vaisheshika school.  Vaisheshika attempts to identify, inventory, and classify the entities that  present themselves to human perception. It lists seven categories of being.  It holds that the universe�s smallest, indivisible, indestructible unit is the  atom, which is made active through God�s will, and that all physical things  are a combination of the atoms of earth, water, fire, and air.</p><p>Vaishnavism VvIsh-no-.vi-zomV Worship of Vishnu as the supreme  deity, as well as of his incarnations, mainly Rama and Krishna. Vaish�  navism is one of the major forms of modern Hinduism, along with Shaivism  and Shaktism, and is probably the most popular and most widely practiced.  Characterized by an emphasis on bhakti, its goal is to escape from the cycle  of birth and death in order to enjoy the presence of Vishnu. The philo�  sophical schools into which Vaishnavism is divided are distinguished by  their varying interpretations of the relationship between individual souls  and God, and include aspects of monism and dualism.</p><p>Vaishya \'vlsh-ya\ Third highest of the four varnas of India. Tradition�  ally described as commoners, Vaishyas are connected with productive  labour, such as trade, agriculture, and pastoralism. According to legend,  they sprang from the thighs of Prajapati, after the Brahmans and the Ksha-  triyas but before the Shudras. Like the two higher classes, they are �twice-  born� (see upanayana). They are credited historically with favouring the  rise of the reformist religious beliefs of Buddhism and Jainism. In modern  times they have become a symbol of middle-class prestige, and many rise  to higher classes.</p><p>Vajiravudh \,va-je-ra-'vud\ or Phramongkutklao V.pra-.moq-kut-  'klau\ or Rama VI (b. Jan. 1, 1881, Bangkok, Siam�d. Nov. 26, 1925,  Bangkok) King of Siam (Thailand; 1910-25). Educated at Oxford, Vajira�  vudh undertook numerous social reforms as king, including making  monogamy the only legal form of marriage. In 1921 he made primary  education free and compulsory. He alienated both liberals and conserva�  tives at home but was successful in foreign policy, restoring full fiscal  autonomy to Siam. A prolific writer and translator, he introduced West�  ern forms to Thai literature, translated William Shakespeare�s works, and  composed about 50 original plays.</p><p>Vajpayee, Atal Bihari (b. Dec. 15, 1924, Gwalior, Madhya Pradesh,  India) Leader of India�s pro-Hindu Bharatiya Janata Party (BJP) and prime  minister of India in 1996 and from 1998 to 2004. Politically active as a  teenager, he was briefly jailed by British colonial authorities. He was first  elected to parliament in 1957 as a member of the Bharatiya Jana Sangh,  a forerunner of the BJP. He served as foreign minister in the late 1970s  and helped formally establish the BJP in 1980. In 1992 he was one of the  few Hindu leaders to speak out against the destruction of the historic Babri  Masjid mosque by anti-Muslim extremists. Elected prime minister in May  1996, he was unable to form a government and resigned after 13 days. In  1998 and 1999 he was again elected prime minister as head of a BJP-led  coalition. In May 1998 nuclear weapons tests ordered by Vajpayee drew  international condemnation and economic sanctions. In 2000 his govern�  ment began an extensive program of divestment of public funds from  several key state-run industries. Under his leadership India achieved  steady economic growth and became a world leader in information tech�  nology. In 2004 his coalition was defeated in parliamentary elections, and  he resigned from office.</p><p>vajra Vvoj-roV Five-pronged ritual object extensively employed in the  ceremonies of Tibetan Buddhism. It is fashioned out of brass or bronze, the  four prongs at each end curving around the central fifth to form a lotus-  bud shape. In Sanskrit the word means both thunderbolt and diamond:  like a thunderbolt it cuts through ignorance, and like a diamond it destroys  but is itself indestructible. Originally a symbol of Indra, it was used to  conquer the non-Buddhist deities of Tibet. In ritual use, it is often  employed in conjunction with a bell in the execution of mudras.</p><p>Vajrayana V.voj-ro-'ya-noN Form of tantric Buddhism that emerged in  India in the first millennium ad and spread to Tibet, where it is the pre�  dominant tradition in Tibetan Buddhism. Philosophically, Vajrayana is a</p><p>blend of the Yogacara and Madhyamika disciplines. It aims to recapture  the enlightenment experience of the Buddha Gautama, and it places spe�  cial emphasis on the notion that enlightenment arises from the realization  that seemingly opposite principles are in truth one. It introduced innova�  tions involving the use of mantras and mandalas as aids to meditation,  and, in rare cases, the use of yogically disciplined sexual activities.</p><p>Vakataka Vva-ko-to-kcA dynasty Indian ruling house that originated  in the central Deccan in the mid-3rd century ad. The Vakataka empire is  believed to have extended from Malwa and Gujarat in the north to the  Tungabhadra in the south and to have spanned the peninsula from west  to east. In the 4th century the Vakatakas were allied by marriage to the  Gupta dynasty, and Gupta cultural influence was significant. The Vakata�  kas are noted for having encouraged arts and letters.</p><p>Valdemar Vval-do-maA I known as Voldemar the Great (b. Jan.  14, 1131, Denmark�d. May 12, 1182, Denmark) King of Denmark  (1157-82). On ascending the throne, he ended more than 25 years of civil  wars, and he defeated the Wends (Slavs) by 1169, freeing Danish ships  from piracy. He acknowledged the overlordship of Frederick I Barbarossa  and accepted his antipope Victor IV; he later acknowledged Pope Alex�  ander III (c. 1165) and rejected Frederick. He gained church approval for  hereditary rule by his dynasty, the Valdemars, and in 1181 he allied with  Frederick as an equal, aided by the marriage of their children.</p><p>Valdemar IV Atterdag Vat-t9r-,dag\ (b. c. 1320, Denmark�d. Oct.  24, 1375, Schleswig) King of Denmark (1340-75). A son of King Chris�  topher II, he sought to free Danish lands from foreign domination. He  sold Estonia (1346), gained control of Zealand (1349), and subdued a  revolt in Jutland (1350). By regaining Skane from Sweden, he completed  the reunification of his father�s kingdom (1360). His aggressive foreign  policy led to conflict with Sweden, North German principalities, and the  Hanseatic League, which defeated him in 1368, forcing him to concede  trading privileges but allowing his kingdom to remain intact. The mar�  riage of his daughter Margaret to the Norwegian king Haakon VI made  possible the unification of Denmark and Norway.</p><p>Valdes \val-'des\ or Peter Waldo (d. c. 1205) French religious leader.  A successful merchant, Valdes (Peter Waldo was a later form of his name)  underwent a religious conversion, gave away his wealth, and began to  preach a doctrine of voluntary poverty in Lyon around 1170. In 1179 his  vow of poverty was confirmed by Pope Alexander III, but he was subse�  quently forbidden to preach by Pope Lucius III. In 1182 or 1183 Valdes  and his followers�called the Poor, or the Poor of Lyon�were excom�  municated for violating the ban on preaching and were banished from the  city. They were formally condemned at a church council in 1184 along  with other heretics, including the Cathari, against whom Valdes had ear�  lier preached. The severe persecution of the so-called Waldenses in the  13th century forced them to begin traveling and teaching in secret. Dur�  ing the Protestant Reformation, the Waldenses accepted Genevan forms of  worship and church organization.</p></section><section><p>Valdes Leal \bal-'das-le-'al\, Juan de (b.

After  the death of Bartolome Esteban Murillo, he was Sevilla�s leading painter.  His early works are marked by exotic colours, dramatic lighting, and vig�  orous brushstrokes. Later paintings such as Vanitas (1660) and Triumph  of Death (1672) are characterized by their macabre subject matter,  dynamic energy, and theatrical violence.</p><p>Valdivia Wal-'de-ve-oV, Pedro de (b. c. 1498, Extremadura,  Spain�d.

In 1540 he led an expedition of 150 Spaniards into Chile, where  he defeated a large force of Indians and founded Santiago in 1541. He  extended Spanish rule south to the Bio-Bio River in 1546, fought again  in Peru (1546-48), and returned to Chile as governor in 1549. He began  to conquer Chile south of the Bio-Bio and founded Concepcion in 1550.  He was killed in a campaign against the Araucanian Indians.</p><p>Vale of Tempe See Vale of Tempe</p><p>Vale of the White Horse See Vale of the White Horse</p><p>valence \'va-bns\ Number of bonds (see bonding) an atom can form.

The valence depends on the number of unpaired electrons in the outer�  most (and, in transition elements, the next) shell of the atom�s structure.  The sharing of the unpaired (valence) electrons in a bond mimics the  stable configuration of the noble gases, whose outer shells are full. Ele�  ments that can achieve stable configurations by various combinations have  more than one valence.</p><p>Valencia Autonomous community (pop., 2001: 4,162,776), eastern  Spain. Encompassing the provinces of Alicante, Castellon, and Valencia,  it covers 8,979 sq mi (23,255 sq km); its capital is the city of Valencia. A  generally mountainous region with salt lagoons on the coast, the area was  conquered successively by Romans, Visigoths, and Moors. Part of the  caliphate of Cordoba (11th century), it subsequently became an indepen�  dent Moorish kingdom. It was held by the Spanish commander the Cid  ( 1094-99); after the Cid�s death Valencia again was lost to the Moors,  until King James I of Aragon took it in 1238. One of the richest farming  regions in the Mediterranean basin, it produces oranges, rice, grapes, and  olives; it also has many manufacturing facilities.</p><p>Valencia City (pop., 2001: city, 738,441; metro, area, 1,397,809), capi�  tal of the autonomous community of Valencia, eastern Spain. First men�  tioned as a Roman settlement in 138 bc, it was later taken by the Visigoths  in ad 413 and the Moors in 714. It became the seat of the newly estab�  lished independent Moorish kingdom of Valencia in 1021. After 1238 it  was part of the dominions of Aragon. The first Spanish printing press  was established in Valencia in 1474; during the next two centuries the  city was the seat of the Valencian school of painting. It was severely dam�  aged in the Peninsular War, during the Spanish Civil War, and by flood in  1957. Its port ships agricultural produce and manufactured items.</p><p>Valencia City (pop., 2000 est.: 1,338,833), northwestern Venezuela. It  is located near the western shore of Lake Valencia. Founded in 1555, it  rivaled Caracas as the region�s major city well into the 19th century. In  1814, during the struggle for Venezuela�s independence, it was the site of  a bloody battle between Spanish and opposition forces. It served as  national capital in 1812, 1830, and 1858. One of Venezuela�s principal  industrial and transportation centres, it produces textiles, pharmaceuticals,  and automobiles.</p><p>Valencia, Lake/ormerfy Tacarigua \,ta-ka-'re-gwa\ Lake, Carabobo  and Aragua states, northern Venezuela.

His older brother, Valentinian I, appointed Valens to be coemperor  and assigned him to rule the eastern part of the empire, while Valentinian  took the throne in the West. An Arian Christian, Valens persecuted Catho�  lics and waged war on the pagan Procopius (366), the Visigoths (367-  369), and the Persians (c. 376). When the Visigoths again rebelled against  the Romans, Valens�s poor tactics led to his defeat and death in the great  Battle of Adrianople.</p><p>Valentine, Saint (d. 3rd century, Rome; feast day February 14) Chris�  tian martyr whose legend inspired the lover�s holiday Valentine�s Day.  According to tradition, he was a Roman priest and physician who died  during the persecution of Christians by the emperor Claudius II Gothicus  and was buried on the Via Flaminia. The priest signed a letter to his jail�  er�s daughter, whom he had befriended and with whom he had fallen in  love, �from your Valentine.� The legend of the bishop of Terni, Italy�  also called Valentine and also martyred in Rome�may refer to the same  person.</p><p>Valentine's Day Lovers� holiday celebrated on February 14, the feast  day of St. Valentine, one of two 3rd-century Roman martyrs of the same  name. St. Valentine is considered the patron of lovers and especially of  those unhappily in love. The feast day became a lovers� festival in the  14th century, probably as an extension of pagan love festivals and fertil�  ity rites celebrated in mid-February. Today it is marked by the exchange  of romantic cards (valentines), flowers, and other gifts.</p><p>Valentinian I \,va-bn-'ti-ne-3n\ in full Flavius Valentinianus (b.</p><p>ad 321, Cibalae, Pannonia�d.

Proclaimed emperor by the army, he made his brother Valens ruler</p><p>in the East while he ruled the West. Both showed religious toleration. Val�  entinian defeated the Alemanni in Gaul in 365, then moved to support the  defense of Britain. He named his nine-year-old son Gratian coemperor  (367) to ensure succession. In Germany he fortified the Rhine; he went  on to fight the Quadi in Pannonia, where he fell sick and died. Despite  his achievements, he was known for his cruelty and poor choice of min�  isters.</p><p>Valentino, Rudolph orig. Rodolfo Guglielmi di Valentina  d'Antonguolla (b.

Later a commander on the upper Rhine, he supported the emperor  Gallus (r. 251-253) in the conflict with a rival emperor but arrived with  his legions too late to save Gallus from death at the hands of his own  troops. Elected emperor by his soldiers (253), Valerian renewed the per�  secution of the Christians and executed Pope Sixtus II in 258. After  appointing his son Publius Licinius Galuenus to rule the western part of the  empire, he marched east to repel the Persian invasion. At first successful,  he was later defeated by the Persian king Shapur I and died in captivity.</p><p>valerian Any of the more than 400 species of annual and perennial her�  baceous plants in about 10 genera that make up the family Valerianaceae.

He was royal secretary and historian for  Alfonso V of Aragon (1435�48). In his polemical style, he criticized the  works of Boethius (for his viewpoint), Aristotle (for his �barbarisms,�  among other things), and Cicero (for his prose style). Found heretical by  the Inquisition for his refusal to believe that the Apostles� Creed was com�  posed by the 12 Apostles, he narrowly avoided being burned at the stake.  His Elegantiae linguae Latinae (printed 1471; �Elegances of the Latin  Language�) was the first textbook of Latin grammar written since late  antiquity.

It became the Maltese  capital in 1570. After 1814 it was made the principal base of the British  Mediterranean naval fleet and remained important through World War II,  during which it suffered heavy damage from bombing raids. Several 16th-  century buildings still exist. The city�s economy relies mainly on trade  and tourism.</p><p>valley Elongate depression of the Earth�s surface.

In the most common method of cal�  culation, the seller subtracts the sum of taxes paid on items being pur�  chased from the sum of all taxes that have been collected on the items  being sold; the net tax liability is the difference between the tax collected  and the tax paid. The burden of the value-added tax, like that of other  sales TAxes, tends to be passed on to the consumer. To limit the VAT�s  regressiveness, most countries set lower rates for consumer necessities  than for luxury items. In 1954 France became the first country to adopt  the value-added tax on a large scale. Though complex to calculate, the tax  served as an improvement on earlier systems by which a product was  taxed repeatedly at every stage of production and distribution. It has since  been adopted throughout much of Europe and in many countries in South  America, Asia, and Africa. All European Union member countries have a  VAT. See also regressive tax.</p><p>valve In mechanical engineering, a device for controlling the flow of  fluids (liquids, gases, slurries) in a pipe or other enclosure. It exerts con�  trol by means of a movable element that opens, shuts, or partially blocks  an opening in a passageway. Valves are of seven main types: globe, gate,  needle, plug (cock), butterfly, poppet, and spool. Some valves operate  automatically; check (or nonreturn) valves, for example, are self-acting  valves that permit flow in only one direction. Safety valves open at a pre�  determined pressure; the movable element usually has a weighted lever  or a spring strong enough to hold the valve closed until a particular pres�  sure is reached.</p><p>bonnet</p><p>seat</p><p>A globe valve controls the flow of a fluid through a pipe, inlet, or outlet.

By daybreak it must return to its grave or to a coffin filled  with its native earth. Tales of vampires are part of the world�s folklore,  most notably in Hungary and the Balkan Peninsula. The disinterment in  Serbia in 1725 and 1732 of several fluid-filled corpses that villagers  claimed were behind a plague of vampirism led to widespread interest  and imaginative treatment of vampirism throughout western Europe.  Vampires are supposedly dead humans (originally suicides, heretics, or  criminals) who maintain a kind of life by biting the necks of living humans</p><p>and sucking their blood; their vic�  tims also become vampires after  death. These �undead� creatures cast  no shadow and are not reflected in  mirrors. They can be warded off by  crucifixes or wreaths of garlic and  can be killed by exposure to the sun  or by an oak stake driven through the  heart. The most famous vampire is  Count Dracula from Bram Stoker�s  novel Dracula (1897).</p><p>vampire bat Any of three species  (family Desmodontidae) of tailless,  brown, blood-eating bats native to  the New World tropics. They grow to  2-3.5 in. (6-9 cm) long and weigh 0.5-2 oz (15-50 g). They run swiftly  and leap with agility. They live in colonies in caves, hollow trees, and  culverts, leaving after dark to forage low on the ground. They feed on  quietly resting birds and mammals, including the occasional human, mak�  ing a small cut with their sharp incisor teeth, often without disturbing the  prey, and lapping the blood.

The ruins of stone buildings there date from the 8th century  bc, when it was the chief centre of the kingdom of Urartu. After the fall  of Nineveh (612 bc), it was occupied in succession by the Medes, the  kings of Pontus, Arabs (7th century ad), and Armenians (8th century ad).  It fell to the Seljuq dynasty after 1071 ad and to the Ottoman Empire in  1543. Russian forces held it (1915-17) during World War I. It has a large  Kurdish population. It once had a large Armenian population that was  brutally expelled following the war (see Armenian massacres).

It is fed by precipitation and meltwater as well as by several small tribu�  taries. It has no apparent outlet, and its brackish waters are unsuitable for  either drinking or irrigation.</p><p>Van Allen radiation belts Two doughnut-shaped zones of highly  energetic charged particles (see electric charge) trapped at high altitudes  in Earth�s magnetic field. Named for James A. Van Allen (b. 1914), who  discovered them in 1958, they are most intense over the Equator and  effectively absent above the poles. The two zones merge gradually, with  the flux of charged particles showing two regions of maximum density.  The inner one, mostly protons thought to be produced by primary cosmic  rays striking the atmosphere, is centred about 3,700 mi (6,000 km) above  Earth�s surface. The outer region includes some helium ions from the  solar wind and is centred about 12,500 mi (20,000 km) above Earth�s sur�  face. Intense solar activity (see solar cycle) causes disruptions of the belts,  linked in turn with such phenomena as auroras and magnetic storms.</p><p>Van Buren, Martin (b. Dec. 5, 1782, Kinderhook, N.Y., U.S.�d. July  24, 1862, Kinderhook) Eighth president of the U.S. (1837-41). He served  in the New York Senate (1812-20) and as state attorney general (1816-19).  An informal group of his political supporters came to be known as the  Albany Regency because they dominated state politics even while Van  Buren was in Washington. He was elected to the U.S. Senate (1821-28),  where he supported states' rights and opposed a strong central government.  After John Quincy Adams became president, he joined with Andrew Jack-  son and others to form a group that later became the Democratic Party. He  was elected governor of New York (1828) but resigned to become U.S. sec�  retary of state (1829-31). He was nominated for vice president at the first  Democratic Party convention (1832) and served under Jackson (1833-37).  As Jackson�s chosen successor, he defeated William H. Harrison to win the  1836 election. His presidency was marked by an economic depression, the  Maine-Canada border dispute (see Aroostook War), the Seminole Wars in  Florida, and debate over the annexation of Texas. He was defeated in his  bid for reelection and failed to win the Democratic nomination in 1844  because of his antislavery views. In 1848 he was nominated for president  by the Free Soil Party but failed to win the election and retired.</p><p>Van Cortlandt, Stephanus (b. May 7, 1643, New Amsterdam�d.

Solids held together  by van der Waals forces typically have lower melting points and are softer  than those held together by ionic, covalent, or metallic bonds (see bond�  ing). The forces arise because neutral molecules, though uncharged, are  usually electric dipoles, which have a tendency to align with each other and  to induce further polarization in neighbouring molecules, resulting in a  net attractive force. They are somewhat weaker than the forces involved  in hydrogen bonding.

In 1832 he finally received a government commission for a  full-length portrait of George Washington and in 1839 another for The  Landing of Columbus in the U.S. Capitol Rotunda.</p><p>Vane, Sir Henry known as Sir Henry Vane the Younger (b.</p><p>1613�d. June 14, 1662, London, Eng.) English politician. Son of the  royal adviser Henry Vane the Elder (1589-1655), he was converted to  Puritanism and in 1635 sailed to New England, where he served as gov�  ernor of Massachusetts (1636-37). After returning to England, he became  treasurer of the navy (1639), then served with his father in the Long Par�  liament, where they helped secure the impeachment of Thomas Wentworth,  1st earl of Strafford. The chief English negotiator of the Solemn League  and Covenant, Vane became leader of the House of Commons (from 1643)  and a member of the Commonwealth�s Council of State (1649-53). After  the Restoration, he was arrested, imprisoned (1660-62), and executed for  treason.</p><p>Vanern Vva-nsmX Lake, southwestern Sweden. The largest lake in Swe�  den and the third largest in Europe, it is about 90 mi (145 km) long, as  much as 322 ft (98 m) deep, and covers an area of 2,156 sq mi (5,585 sq  km). Fed by numerous rivers, it drains into the Kattegat strait via the Gota  River.</p><p>Vanguard Any of three unmanned U.S. experimental satellites. Van�  guard I (1958), the second U.S. satellite placed in orbit around Earth (after  Explorer 1), was a tiny 3.25-lb (1.47-kg) sphere with two radio transmit�  ters. Its flight path revealed that Earth is almost imperceptibly pear-  shaped, confirming earlier theories. Vanguard II (1959) carried light-  sensitive photocells to provide information about Earth�s cloud cover, but  its tumbling motion rendered the data unreadable. Vanguard III (1959)  was used to map Earth�s magnetic field.</p><p>vanilla Any member of a group of tropical climbing orchids that make  up the genus Vanilla, and the flavouring agent extracted from its seed-  pods. The plant has a long, fleshy climbing stem that attaches itself by  aerial rootlets to trees; roots also penetrate the soil. Numerous flowers  open a few at a time and last only a day. The fruit, a bean pod about 8 in.  (20 cm) long at maturity, is harvested as soon as it turns golden green at  the base. Curing and processing turn the pods a deep chocolate brown.  Vanilla is used in a variety of sweet foods and beverages as well as in  perfumery.</p><p>Vanir \'va-,nir\ In Germanic religion, the group of gods responsible for  wealth, fertility, and commerce. They included Njord and his children,  Freyr and Freyja, among others. They were originally subordinate to the  warlike Aesir, but, after defeating the Aesir in battle, they were granted  equal status. The Vanir sent Njord and Freyr to live with the Aesir and  received Hoenir and Mimir in exchange. The birth of Kvasir resulted from  the peace ritual between the two groups.</p><p>Vanua Levu V.van-.wa-'la-viA Island (pop., including adjacent islands,  1996: 139,526), Fiji. Fiji�s second largest island, it is 2,137 sq mi (5,535  sq km) in area. Sighted by the Dutch navigator Abel Janszoon Tasman in  1643, the volcanic Vanua Levu (meaning �Great Land�) has a central  mountain range, culminating at Mount Nasorolevu (3,386 ft [1,032 m]),  which divides the island into wet and dry sections.

The population is nearly all indigenous Melane-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>vapor lamp &#x25BA; variation I 1987</p><p>sian. Languages: Bislama, English, French (ah official); Melanesian lan�  guages and dialects. Religions: Christianity (mostly Protestant; also  Roman Catholic); also traditional beliefs. Currency: vatu. Extending  north-south some 400 mi (650 km), Vanuatu includes the islands of Espiritu  Santo, Pentecost (Pentecote), Malakula, Efate, Ambrym, Erromango,  Tanna, Aoba, Epi, and Maewo. The larger islands are volcanic in origin  and mountainous; there are several active volcanoes. Some of them, espe�  cially Efate and Malakula, have good harbours. The highest point is  Mount Tabwemasana (6,165 ft [1,879 m]) on Espiritu Santo. The devel�  oping free-market economy is based mainly on agriculture, cattle raising,  and fishing. Tourism is increasingly important. Vanuatu is a republic with  a single legislative house; its chief of state is the president, and the head  of government is the prime minister. The islands were inhabited for at  least 3,000 years by Melanesian peoples before being discovered in 1606  by the Portuguese. They were rediscovered by French navigator Louis-  Antoine de Bougainville in 1768, then explored by English mariner Capt.  James Cook in 1774 and named New Hebrides. Sandalwood merchants  and European missionaries arrived in the mid-19th century; they were  followed by British and French cotton planters. Control of the islands was  sought by both the French and British, who agreed in 1906 to form a con�  dominium government. During World War II a major Allied naval base  was on Espiritu Santo; Vanuatu escaped Japanese invasion. New Hebrides  became the independent Republic of Vanuatu in 1980. Much of its his�  tory since then has been marked by political instability.</p><p>vapor lamp See electric discharge lamp</p><p>vaporization Conversion of a substance from the liquid or solid phase  into the gaseous (see gas), or vapour, phase. It includes boiling, in which  vapour bubbles form in a liquid, and sublimation, in which a solid is con�  verted directly to vapour. Vaporization requires that HEAT (the substance�s  latent heat of vaporization) be supplied to the liquid or solid; the same  amount of heat is released by the substance in condensation, the reverse  of vaporization. If the surroundings do not supply enough heat, the tem�  perature of the remaining substance undergoing vaporization drops.

While working as a manservant for an affluent amateur golfer on  the island of Jersey, Vardon learned golf, and he turned professional at  age 20. A technical innovator, he won the British Open six times (1896,  1898, 1899, 1903, 1911, and 1914) and the U.S. Open once (1900).

Forbid�  den to study music by his father, he  secretly continued his studies and  entered the Schola Cantorum with  the help of his cousin, the pianist  Alfred Cortot (1877-1962). He soon  moved to Berlin, where he met Fer�  ruccio Busoni and Richard Strauss,  musicians in tune with his forward�</p><p>looking ideas. His Bourgogne (1907) caused a scandal because of its dis�  sonance. His budding conducting career was interrupted by World War I,  and he moved to the U.S. In 1921 he cofounded the International Com�  posers Guild. His output was small, but every piece became a classic,  including Ojfrandes, Ameriques (both 1921), Hyperprism, Octandre (both  1923), Arcana (1927), and Ionisation (1931), works remarkable for the  way they used instruments, especially percussion, to create blocks of  sound. After the early 1950s, when he finally gained access to the elec�  tronic sound equipment he desired, he concentrated on electronic music.</p><p>Vargas Vvar-gos\, Getulio (Dorneles) (b. April 19,1883, Sao Borja,  Braz.�d. Aug. 24, 1954, Rio de Janeiro) President of Brazil (1930-45,  1951-54). He was elected governor of Rio Grande do Sul in 1928 and ran  unsuccessfully for president in 1930, but later that year he overthrew the  government to become head of state. In 1937 he abolished the constitu�  tional government and set up the totalitarian New State, under which the  previously autonomous states became dependent on central authority. He  enacted labour reforms and social-security laws, introduced extensive  educational reforms, enfranchised women, and granted the secret ballot.  Deposed by a coup in 1945, he was elected president again in 1951;  restrained by a congress and public opinion, he was unable to hold sup�  port and, faced with forced retirement, took his own life.</p><p>Vargas Llosa \'bar-gas-'yo-sa\, (Jorge) Mario (Pedro) (b. March  28, 1936, Arequipa, Peru) Peruvian writer. Vargas Llosa worked as a jour�  nalist and broadcaster before publishing The Time of the Hero (1963), his  widely acclaimed first novel. It describes adolescents striving for survival  in the hostile environment of a military school, the corruption of which  reflects the larger malaise afflicting Peru. His commitment to social  change is evident in his early novels, essays, and plays. He turned increas�  ingly conservative, especially in the face of the Maoist Shining Path insur�  gency, and in 1990 he ran for president of Peru. His best-known works  include The Green House (1965), Aunt Julia and the Scriptwriter (1977),  and The War of the End of the World (1981), an account of a 19th-century  Brazilian religious movement. In 1994 he won the Cervantes Prize (a  prestigious literary award given for Spanish-language literature).</p><p>variable In algebra, a symbol (usually a letter) standing in for an  unknown numerical value in an equation. Commonly used variables  include x and y (real-number unknowns), z (complex-number unknowns),  t (time), r (radius), and s (arc length). Variables should be distinguished  from coefficients, fixed values that multiply powers of variables in poly�  nomials and algebraic equations. In the quadratic equation ax 2 + bx + c =  0, x is the variable, and a, b, and c are coefficients whose values must be  specified to solve the equation. In translating word problems into alge�  braic equations, quantities to be determined can be represented by vari�  ables.</p><p>variable, complex See complex variable  variable, random See random variable</p><p>variable star Star whose observed brightness varies noticeably in  intensity. Pulsating variables expand and contract in cycles, pulsating  rhythmically in brightness and size. Explosive variables include novas  and supernovas, which brighten rapidly due to sudden outbursts of radi�  ant energy; the increased brightness lasts a short time, followed by rela�  tively slow dimming. Eclipsing variable stars are variable only because light  from one star is blocked by another in Earth�s direction. Hundreds of  thousands of variable stars are known. See also binary star; Cepheid vari�  able; flare star; pulsar; T Tauri star.</p><p>variation In biology, any difference between cells, individual organ�  isms, or groups of organisms within a species caused either by genetic  differences (variation in genotype) or by the effect of environmental fac�  tors on the expression of genetic potentials (variation in phenotype). Varia�  tion may be shown in physical appearance, metabolism, fertility, mode of  reproduction, behaviour, learning and mental ability, and other obvious or  measurable characters. Genotypic variations are caused by differences in  number or structure of chromosomes or by differences in the genes carried  by the chromosomes. Eye colour, body form, and disease resistance are  genotypic variations. Phenotypic variations may result from factors such  as climate, food supply, and actions of other organisms. Phenotypic varia�  tions also include stages in an organism�s life cycle and seasonal varia�  tions in an individual. Because they do not involve hereditary alteration  and in general are not transmitted to future generations, phenotypic varia�  tions are not important in evolution.

The simplest variation type  is the variation set, in which two or more sections are based on the same  musical material, which is treated with different variational techniques in  each section. The practice, originally involving use of a repeated bass line  (basso ostinato, or ground bass), began in early 16th-century dance music  in Italy and Spain. Ground-bass forms include the chaconne and passa-  caglia, both of which usually employ a brief bass line repeated many  times. In the 17th century, organ and harpsichord variations became a  standard form in Germany. Keyboard variations in the 19th century often  employed popular tunes or opera melodies; variation form was also com�  monly used in symphonies, quartets, and sonatas. It declined in impor�  tance after the classical era but has never ceased to be employed by  composers. The music of certain non-Western cultures also uses varia�  tional techniques. The art music of southern India is built on the concept  of a string of pieces, each a variation on a given �theme.� A somewhat  different concept of multilevel variation is found in the gamelan (orches�  tra) music of Indonesia. The variations are not consecutive but are simul�  taneous, a technique called heterophony.</p><p>varicella See chicken pox</p><p>varicose Vvar-o-.kosV vein or varix Twisted vein distended with  blood. Varix also covers arteries and lymphatic vessels (see lymphatic sys�  tem). Varicose veins occur mostly in the legs, when malfunctioning valves  let blood pool in veins near the skin. Causes include hereditary valve and  vein wall weakness and internal or external pressure on veins. Varices are  common in pregnancy, suggesting that hormone abnormalities play a role.  Symptoms include a heavy feeling, with leg cramps and swelling after  standing a long time. Complications include skin ulcers and thrombosis.  Treatment involves strong support hose, injection therapy, or surgery.  Varices in the esophagus, which often occur in liver disease, can ulcerate  and bleed.

He joined the faculty of UC-San Francisco in 1970. With  J. Michael Bishop, he discovered that, under certain circumstances, normal  genes in healthy body cells can cause cancer. These oncogenes ordinarily  control cell division and growth, but viruses or carcinogens can activate  them. Their research superseded a theory that cancer is caused by viral  genes, distinct from a cell�s normal genetic material, that lie dormant until  activated by carcinogens. For their work, the two shared a 1989 Nobel  Prize. Varmus later served as director of the National Institutes of Health  (1993-99) and became president of Memorial Sloan-Kettering Cancer  Center.</p><p>Varna Seaport city (pop., 2001: 314,539), Bulgaria, on the Black Sea  coast. Founded as Odessus by Milesian Greeks in the 6th century bc, it  later was Thracian, Macedonian, and Roman. In ad 681 it became part of  the first Bulgarian empire (c. 679-1018) and was named Varna. It came  under Ottoman domination in 1391. In 1444 it was the scene of a battle  between Turkish and Hungarian armies in which Wladyslaw III, king of  Poland and Hungary, was killed. Varna was ceded to Bulgaria by the 1878  Treaty of Berlin (see Congress of Berlin). It is an important administra�  tive, economic, cultural, and resort centre. Shipbuilding and manufactur�  ing are important industries.</p><p>varna Vvor-noV Any of the four traditional social classes of Hindu India.  One of the hymns of the Rigveda declares that the Brahman, the Kshatriya,  the Vaishya, and the Shudra issued forth at creation from the mouth, arms,  thighs, and feet of Prajapati. Traditional lawmakers specified a set of obli�  gations, observed mainly in theory only, to each vama: the Brahman, to  study and advise; the Kshatriya, to protect; the Vaishya, to cultivate; and  the Shudra, to serve. An unofficial fifth class, the pancama, was created  to include certain untouchables and tribal groups falling outside this sys�  tem. The relationship of the caste system to the class system is complex;  individual castes, of which there are dozens, have sought to raise their  social rank by identifying with a particular varna, demanding the associ�  ated privileges of rank and honour.</p><p>Varna, Battle of (November 10, 1444) Turkish victory over the Hun�  garians that marked the end of the European effort to protect Constanti�  nople. The Hungarians under Janos Hunyadi broke a truce and marched  to Vama (in present-day Bulgaria), where they fought the Turks under</p><p>Sultan Murad II and were defeated; the Hungarian king Ulaszlo I (also  ruler of Poland) was killed in the battle. The victory enabled the Ottoman  Empire to gain control of the Greek Peloponnese, conquer Constantino�  ple (1453), and reabsorb Serbia (by 1459).</p><p>Varro \'var-o\, Marcus Terentius (b. 116, probably Reate [Italy]�d.  27 bc) Roman scholar and satirist. Varro was active in public life, rising to  the office of praetor. He sided with Pompey the Great but later reconciled  with Julius Caesar. A prolific writer, he sought in his writings to inculcate  moral virtues and to link Rome�s future with its glorious past. He is best  known for his Saturae Menippeae (�Menippean Satires�), medleys in  mixed prose and verse that mock the absurdities of modern times. He wrote  some 75 works in more than 600 books on a wide range of subjects�  jurisprudence, astronomy, geography, education, and literary history�as  well as in a variety of genres�satires, poems, orations, and letters.</p><p>Varus \'var-3s\, Publius Quintilius (d. ad 9) Roman general. He was  bom a patrician; his father was one of the murderers of Julius Caesar.  Varus crushed the rebellion in Judaea (4 bc) and reestablished Roman  control. Assigned to the frontiers east of the Rhine, he tried to assert  Roman jurisdiction, but he was overwhelmed by a German attack in the  Teutoburg Forest and lost three legions. Disgraced, he killed himself by  falling on his sword. His defeat led to the loss of all Roman possessions  east of the Rhine.</p><p>varved deposit \'varvd\ Any form of repetitive sedimentary rock  stratification that was deposited within a year. This annual deposit usu�  ally consists of paired contrasting layers (varves) of alternately finer  (darker) and coarser (lighter) silt or clay, reflecting seasonal variations in  sedimentation (winter and summer) within the year. Varved deposits are  most commonly found in glacial lakes, but they can also be found in non�  glacial lakes and marine settings.</p><p>varying hare See snowshoe hare</p><p>Vasa dynasty Swedish (and Polish) royal dynasty. Its founder was  Gustav Eriksson Vasa, regent of Sweden (1521) and king (1523) as Gustav  I Vasa. His descendants reigned in Sweden until 1818, the last being Charles  XIII. A grandson of Gustav became king of Poland (1587-1632) as  Sigismund III Vasa, also ruling Sweden in the years 1592-99. He was suc�  ceeded as king of Poland by his sons, Wladyslaw IV Vasa (r. 1632-48) and  John II Casimir Vasa (r. 1648-68), after which the dynasty ended in Poland.</p><p>Vasarely \,va-z3-'re-le\, Victor orig.

Trained in Budapest in the Bauhaus tradition, he moved to Paris in  1930 and supported himself as a commercial artist. In the 1930s he was  influenced by Constructivism, but by the 1940s he was painting animated  surfaces of geometric forms and interacting colours. His style reached  maturity in the mid 1950s and 1960s, with the use of more vibrant colours  to increase the sense of movement through optical illusion, as in Sirius II  (1954), and he became one of the leading figures of the Op art movement.</p><p>Vasari \va-'za-re\, Giorgio (b. July 30, 1511, Arezzo�d. June 27,  1574, Florence) Italian painter,  architect, and writer. Though he was  a prolific painter in the Mannerist  style, he is more highly regarded as  an architect (he designed the Uffizi  Palace, now the Uffizi Gallery), but  even his architecture is overshad�  owed by his writings. His Lives of  the Most Eminent Architects, Paint�  ers, and Sculptors (1550) offers  biographies of early to late Renais�  sance artists. His style is eminently  readable and his material is well  researched, though when facts were  scarce he did not hesitate to fill in the  gaps. In his view, Giotto had revived  the art of true representation after its  decline in the early Middle Ages, and  succeeding artists had brought that  art progressively closer to the per�  fection achieved by Michelangelo.</p><p>The work�s second edition (1568)  has proved an invaluable resource for art historians.</p><p>Vasari, self-portrait, oil painting; in the  Uffizi, Florence</p><p>SCALA/ART RESOURCE, NEW YORK</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Vasconcelos &#x25BA; Vatican Palace I 1989</p><p>Vasconcelos \,bas-kon-'sa-los\, Jose (b.

As minister of education (1920-24)  he initiated major reforms in Mexico�s school system, especially expan�  sion of the rural school program. He ran unsuccessfully for president in  1929. Vasconcelos�s political activism forced him into exile several times.  He regarded the indigenous Indian culture as transcending Western cul�  ture.

Ferns, gymnosperms, and flowering plants are all vascular  plants. In contrast to the non vascular bryophytes, the more conspicuous  generation among vascular plants is the sporophyte (see alternation of gen�  erations). Because they have vascular tissues, these plants have true stems,  leaves, and roots, modifications of which enable species of vascular plants  to survive in a variety of habitats under diverse, even extreme, environ�  mental conditions. This ability to flourish in so many different habitats is  the primary reason that vascular plants have become dominant among ter�  restrial plants.</p><p>vasectomy \v9-'sek-t3-me\ Severing of the vas deferens, which carries  sperm from the testes to the prostate gland, to cause sterility or prevent  infection. This relatively simple procedure, which can be performed in a  doctor�s office with local anesthetics, removes the ability to father chil�  dren without affecting ability to achieve erection or orgasm. The vas is  cut near its beginning, in the scrotum. The cut ends may be sealed off or  left open.

Despite being blinded by his cousin Dmitry Shemyaka, he regained power  in 1447 and ruled Muscovy for another 15 years. Vasily quelled internal  strife in his realm by 1452 and enlarged his state�s territory by absorbing  nearby principalities.

Among the most notable of the 16 documents enacted  were the �Dogmatic Constitution on the Church,� which treats church  hierarchy and provides for greater involvement of laypeople in the church;  the �Dogmatic Constitution of Divine Revelation,� which maintains an  open attitude toward scholarly study of the Bible; the �Constitution on the  Sacred Liturgy,� which provides for the use of vernacular languages in  the mass in place of Latin; and the �Pastoral Constitution on the Church  in the World of Today,� which acknowledges the profound changes  humanity has experienced in the modern world and attempts to relate the  church to contemporary culture. Observers from other Christian churches  were invited to the council in a gesture of ecumenism.</p><p>Vatican Museums and Galleries Institutions and papal palaces in  Vatican City housing the art collections of the popes since the beginning  of the 15th century. Among the many separate museums are the 18th-  century Pio-Clementino Museum, which exhibits the collection of Clas�  sical sculpture that originated in 1503-13 with Julius II; the exhibition  rooms in the Vatican Library; and the Sistine Chapel. The Vatican collec�  tions are most famous for their Classical statues (including Apollo Belve�  dere, Belvedere Torso , and Laocoon ) but also contain important examples  of Egyptian and early Christian art. The Pinacoteca (�Picture Gallery�),  founded by Pius VI in 1797, contains Italian religious paintings and Rus�  sian and Byzantine art. In 1956 a modem-art collection was begun with  secular works by such artists as Pierre-Auguste Renoir, Georges Seurat,  Vincent van Gogh, Henri Matisse, and Pablo Picasso.

Under Julius II, Giovanni dei Dolci built the Sistine Chapel, noted  for its spectacular interior artwork including Michelangelo�s ceiling;  Donato Bramante completed the palace�s northern facade and planned the  immense Belvedere court; and Raphael painted his masterpieces in the  palace. Antonio da Sangallo the Younger, employed by Paul III. designed  the Sala Regia (Royal Hall) and Pauline Chapel, decorated by Michelan�  gelo. Several chapels, along with Ottaviano Mascherino�s famous Gallery  of Maps, date from the late 16th century. Domenico Fontana added a wing  of apartments and the present library building under Sixtus V. In the  Baroque period. Urban VIII built the Matilda Chapel and, under Alex�  ander VII, Gian Lorenzo Bernini built the Scala Regia (Royal Stairway).</p><p>Vatnajokull Yvat-na-,yce-ku-t 3 l\ Extensive ice field, southeastern Ice�  land. It covers an area of 3,200 sq mi (8,400 sq km) and has an average  ice thickness of more than 3,000 ft (900 m).

After fighting with the forces of the Conde family (1651�  53), he switched to the royalist side and joined the newly formed engi�  neer corps, becoming engineer in chief at the siege of Gravelines (1658).  He designed fortifications for numerous French towns and outposts and  devised tactics that led to many successes in the French wars of Louis XIV�s  reign; his innovations revolutionized the art of siege tactics and defensive  fortification. He also introduced the tactic of ricochet gunfire and invented  the socket bayonet. His treatises on fortification and siege-craft were stud�  ied for more than 100 years. He was made a marshal of France in 1703.</p><p>Vaucanson \vo-kau- , so I1 \ / Jacques de (b. Feb. 24, 1709, Grenoble,  France�d. Nov. 21, 1782, Paris) French inventor. In 1739 he constructed  an automaton, �The Duck,� which imitated not only the motions of a live  duck but also the motions of drinking, eating, and �digesting.� An inspec�  tor of silk manufacture, Vaucanson automated the loom by means of per�  forated cards that guided hooks connected to the warp yams (see weaving).  His innovation was ignored for decades until J.-M. Jacquard reconstructed  and improved on it; the Jacquard loom became one of the most impor�  tant inventions of the Industrial Revolution.</p><p>Vaucheria \vo-'kir-e-9\ Genus of yellow-green algae. It is character�  ized by oil food reserves and tubular branches that have multiple nuclei  and lack cross-walls except in association with reproductive organs or an  injury. Vaucheria reproduce both asexually and sexually. The spherical  female sex organ and the slender, hook-shaped male sex organ are usu�  ally produced on branches close to each other. After fertilization, the  zygote may enter a resting phase for several weeks before developing into  a new plant. Though most species occur in freshwater or are terrestrial,  some are marine and others live in ice.</p><p>vaudeville \'v6d-,vil\ Light entertainment popular in the U.S. in the  late 19th and early 20th centuries. It consisted of 10-15 unrelated acts  featuring magicians, acrobats, comedians, trained animals, singers, and  dancers. The form developed from the coarse variety shows held in beer  halls for a primarily male audience. Tony Pastor established a successful  �clean variety show� at his New York City theatre in 1881 and influenced  other managers to follow suit. By 1900 chains of vaudeville theatres  around the country included Martin Beck�s Orpheum Circuit, of which  New York�s Palace Theatre was the most famous (1913-32). Among the  many entertainers who began in vaudeville were Mae West, W.C.

He  played a major role in standardizing the French language of literature and  of polite society. His Remarks on the French Language, Useful for Those  Who Wish to Speak Well and Write Well (1647) became an authoritative</p><p>guide to French usage, and his writings formed the basis of the rules for  pure and elegant French promulgated by the Academie Francaise, of which  he was an original member.</p><p>Vaughan Won, 'van\, Henry (b.

After writing two volumes of secular poems, he read the religious poet  George Herbert and gave up �idle verse.� He is chiefly remembered for  the spiritual vision or imagination evident in his fresh and convincing  religious verse and is considered one of the major practitioners of Meta�  physical poetry. Works that reveal the depth of his religious convictions  include Silex Scintillans (1650, enlarged 1655; �The Glittering Flint�) and  the prose Mount of Olives (1652). He also translated short moral and reli�  gious works and two medical works.</p><p>Vaughan, Sarah (Lois) (b. March 27, 1924, Newark, N.J., U.S.�d.

Vaughan won an  amateur contest at Harlem�s Apollo  Theatre in 1942 and soon joined Earl  Hines�s big band as vocalist and sec�  ond pianist. Joining Billy Eckstine�s  band in 1944, she gained exposure to  the new bebop style; she was espe�  cially influenced by Dizzy Gillespie  and Charlie Parker and recorded with  them in 1945. Alternating between  popular song and jazz, she worked as  a soloist for the rest of her career. A  vast range and wide vibrato in the  service of her harmonic sensitivity  enabled Vaughan to use her voice  with a seemingly instrumental  approach, often improvising as a jazz  soloist.</p><p>Vaughan Williams \v6n-'wil-y3ms\, Ralph (b. Oct. 12,1872, Down  Ampney, Gloucestershire, Eng.�d. Aug. 26, 1958, London) British com�  poser. He attended the Royal College of Music and Cambridge Univer�  sity, and he also studied in Berlin with the composer Max Bruch. Having  collected English folk songs for his academic work, he combined folk  melody with modern approaches to harmony and rhythm, forging a musi�  cal style at once highly personal and deeply English. His nine sympho�  nies, including Sea Symphony (1909), London Symphony (1913), and  Sinfonia Antarctica (1952), were his most exploratory works. Other popu�  lar pieces include The Lark Ascending (1914) and Serenade to Music  (1938); he also wrote five operas, including Riders to the Sea (1936). He  conducted extensively throughout his life, and he edited The English Hym�  nal (1904-06).</p><p>vault In building construction, an arched structure forming a ceiling or  roof. The masonry vault exerts the same kind of thrust as the arch, and  must be supported along its entire length by heavy walls with limited  openings. The basic barrel vault, in effect a continuous series of arches,  first appeared in ancient Egypt and the Middle East. Roman architects  discovered that two barrel vaults intersecting at right angles (a groin vault)  could, when repeated in series, span rectangular areas of unlimited length.  Because the groin vault�s thrusts are concentrated at the four comers, its  supporting walls need not be massive. Medieval European builders devel�  oped the rib vault, a skeleton of arches or ribs on which the masonry could  be laid. The fan vault, popular in the English Perpendicular style, used fan�  shaped clusters of tracery-like ribs springing from pendants or columns.  The 19th century saw the use of large iron skeletons as frameworks for  vaults of lightweight materials (see Crystal Palace). An important modern  innovation is the reinforced-concrete shell vault, which, if its length is  three or more times its transverse section, behaves as a deep beam and  exerts no lateral thrust. See illustration opposite.</p><p>vaulting Gymnastics exercise in which the athlete leaps over a form that  was originally intended to mimic a horse. At one time, the pommel horse was  used in the vaulting exercise, with the pommels (handles) removed. The  sanctioning body for gymnastic sport, the Federation Internationale de  Gymnastique (FIG), decreed in 2001 that a vaulting table would be intro�  duced to replace the horse. In men�s vaulting the height of the table is 1.35  m (4.43 ft) from the floor; for women, the height is 1.20 m (3.94 ft).

Through expeditions to many parts of the world,  Vavilov amassed an immense plant collection and conceived the theory  that a cultivated plant�s centre of origin would be found in the region in  which wild relatives of the plant showed maximum adaptiveness. He  eventually proposed 13 world centres of plant origin. Though widely con�  sidered one of the greatest specialists in botanical populations, he was  publicly condemned by Trofim Lysenko at successive plant-breeding con�  gresses (1934-39) as peddling �Mendelist-Morganist genetics� (see Gre�  gor Mendel; Thomas Hunt Morgan), and he died in a concentration camp.</p><p>vCard Electronic business card that automates the exchange of personal  information typically found on a traditional business card.

Although he taught economics at the University of Chi�  cago and other universities, he was unable to keep any position for long  because of his unconventional ideas and the disorder in his personal life.  In 1899 he published his classic work The Theory of the Leisure Class,  which applied Darwin�s evolutionary theories to the study of modem  economic life, highlighting the competitive and predatory nature of the  business world. With dry humour he identified the markers of American  social class, and he coined the term �conspicuous consumption� to  describe the display of wealth made by the upper class. His reputation  was highest in the 1930s, when the Great Depression was seen as a vin�  dication of his criticism of the business system.</p><p>vector In mathematics, a quantity characterized by magnitude and direc�  tion. Some physical and geometric quantities, called scalars, can be fully  defined by a single number specifying their magnitude in suitable units  of measure (e.g., mass in grams, temperature in degrees, time in seconds).  Quantities like velocity, force, and displacement must be specified by a  magnitude and a direction. These are vectors. A vector quantity can be  visualized as an arrow drawn in a specific direction, whose length is equal  to the magnitude of the quantity represented. A two-dimensional vector  is specified by two coordinates, a three-dimensional vector by three coor�  dinates, and so on. Vector analysis is a branch of mathematics that  explores the utility of this type of representation and defines the ways  such quantities may be combined. See also vector operations.</p><p>vector operations Extension of the laws of elementary algebra to  vectors. They include addition, subtraction, and three types of multipli�  cation. The sum of two vectors is a third vector, represented as the diago�  nal of the parallelogram constructed with the two original vectors as sides.  When a vector is multiplied by a positive scalar (i.e., number), its mag�  nitude is multiplied by the scalar and its direction remains unchanged (if  the scalar is negative, the direction is reversed). The multiplication of a  vector a by another vector b leads to the dot product, written a � b, and  the cross product, written a x b. The dot product, also called the scalar  product, is a scalar real number equal to the product of the lengths of  vectors a (|a|) and b (|b|) and the cosine of the angle (0) between them:  a &#x25A0; b = |a| |b| cos 0. This equals zero if the two vectors are perpendicular  (see orthogonality). The cross product, also called the vector product, is  a third vector (c), perpendicular to the plane of the original vectors. The  magnitude of c is equal to the product of the lengths of vectors a and b  and the sine of the angle (0) between them: |c| = |a| |b| sin 0. The asso�  ciative law and commutative law hold for vector addition and the dot prod�  uct. The cross product is associative but not commutative.</p><p>vector space In mathematics, a collection of objects called vectors,  together with a field of objects (see field theory), known as scalars, that  satisfy certain properties. The properties that must be satisfied are: (1) the  set of vectors is closed under vector addition; (2) multiplication of a vec�  tor by a scalar produces a vector in the set; (3) the associative law holds  for vector addition, u + (v + w) = (u + v) + w; (4) the commutative law  holds for vector addition, u + v = v + u; (5) there is a 0 vector such that  v + 0 = v; (6) every vector has an additive inverse (see inverse function),  v + (-v) = 0; (7) the distributive law holds for scalar multiplication over  vector addition, n(u + v) = mi + n\ (8) the distributive law also holds  for vector multiplication over scalar addition, (m + n)\ = mv + n\ (9) the  associative law holds for scalar multiplication with a vector, ( mn)\ =  m ( nv ); and (10) there exists a unit vector 1 such that lv = v. The set of  all polynomials in one variable with real coefficients is an example of a  vector space.</p><p>Ved-ava Vva-da-va\ Divine ruler of the waters and their bounty, com�  mon to several Baltic and Finno-Ugric peoples traditionally dependent on  fishing.

Its three fundamental texts are the Upanishads, the Bhaga-  vadgita, and the Brahma Sutras, which are very brief interpretations of the  doctrine of the Upanishads. Several schools of Vedanta have developed,  differentiated by their conception of the relationship between the self  (atman) and the absolute (Brahman). They share beliefs in samsara and the  authority of the Vedas as well as the conviction that Brahman is both the  material and instrumental cause of the world and that the atman is the  agent of its own acts and therefore the recipient of the consequences of  action (see karma).</p><p>Vedic religion \'va-dik\ or Vedism Ancient religion of India that was  contemporary with the composition of the Vedas and was the precursor  of Hinduism. The religion of the Indo-European-speaking peoples who  entered India c. 1500 bce from the region of present-day Iran, it was a  polytheistic system in which Indra was the highest-ranked god. It involved  the worship of numerous male divinities connected with the sky and natu�  ral phenomena. Ceremonies centred on ritual sacrifice of animals and on  the use of soma to achieve trancelike states. These ceremonies, simple in  the beginning, grew to be so complex that only trained Brahmans could  carry them out correctly. Out of Vedism developed the philosophical con�  cepts of atman and Brahman. The spread (8th-5th century bce) of the  related concepts of reincarnation, karma, and release from the cycle of  rebirth through meditation rather than sacrifice marked the end of the  Vedic period and the rise of Hinduism. The Hindu initiation ceremony,  upanayana, is a direct survivor of Vedic tradition.</p><p>Veeck \'vek. Bill in full William Louis Veeck (b. Feb. 9, 1914,  Hinsdale, Ill., U.S.�d.

After serv�  ing with the Spanish Armada, he lived in Madrid, serving as secretary to  a series of nobles, including the duke of Sessa (from 1605). Called the  �Phoenix of Spain,� the phenomenally prolific Vega wrote as many as  1,800 plays, of which 431 survive, and established the comedia (tragi�  comic social drama), which typified the new Golden Age drama. He wrote  two major types of drama, both Spanish in setting: the historical play  based on a national legend (e.g., Peribahez and The King, the Greatest  Alcalde) and the �cloak-and-sword� drama of contemporary manners and  intrigue, which turned on some �point of honour� (e.g.. The Gardener's  Dog). He established the comic character, or gracioso, as a commentator  on the follies of his social superiors. All Citizens Are Soldiers is his best-  known work outside Spain. He also wrote 21 volumes of nondramatic  works in verse and prose, including The New Art of Writing Plays (1609).</p><p>vegetable In the broadest sense, all plant life and plant products (veg�  etable matter); in common, narrow usage, the fresh edible portion of her�  baceous plants (roots, stems, leaves, flowers, or fruit), either eaten fresh  or prepared in some way. Almost all current vegetables were cultivated  in ancient Old or New World civilizations, though some have been greatly  modified. Vegetables are good sources of minerals (especially calcium and  iron), vitamins (especially A and C), and dietary fiber. All the amino acids  needed to synthesize protein are available in vegetables. Fresh vegetables  quickly age and spoil, but their storage life can be extended by such pres�  ervation methods as dehydration, canning, freezing, fermenting, and pick-  ling.</p><p>vegetable oyster See salsify</p><p>vegetarianism Theory or practice of eating only plants. The vegetar�  ian diet includes grains, vegetables, fruits, and nuts; it excludes meat,  poultry, and fish, but some vegetarians eat dairy products (lactovegetar-  ians), egg products (ovovegetarians), or both (ovolactovegetarians). Those  who eat no animal products (including honey) are called vegans. Moti�  vations vary and include ethics (both unwillingness to kill animals and  abhorrence of modern methods of raising animals for meat), self-denial  or religious taboo, ecology (including concern about the wastefulness and  environmental costs of beef farming), and health. Vegetarians point to the  many health benefits of their diet, including low rates of heart disease,  diabetes, colon cancer, and obesity. While obtaining sufficient protein is  seldom a problem in affluent societies, vegetarians must be careful to  consume enough iron and, especially for vegans, calcium and vitamins D  and B 12 . The most influential early proponent of vegetarianism was  Pythagoras, in the 6th century bc. Many Hindu sects and most Buddhists  are vegetarian, and much of the world eats hardly any meat because it is  unavailable. The Enlightenment led to a humane concern for animals; in  the 19th century Britain became a major centre of vegetarianism, and  vegetarian movements soon arose in Germany, the U.S., and other coun�  tries.</p><p>Veii Vve-yi, 'va-ye\ Ancient Etruscan town.

After arriving in Madrid in 1623, he painted a  portrait of Philip IV that won him immediate success and an appointment  as court painter. His position gave him access to the royal collections,  including works by Titian, who exerted the greatest influence on his style.  In his portraits from this period, only the faces and hands of the figures  are accentuated, and the dark figures stand out against a light background.  A visit to Italy (1629-31) further developed his style, and on his return  to Madrid he entered his most productive period. Velazquez created a new  type of informal royal portrait for Philip�s hunting lodge, and his portraits  of court dwarfs display the same discerning eye as those of his royal sub�  jects.

The powerful head, brilliant combinations of crimson of the  curtain, chair, and cope are painted with fluent technique and almost  imperceptible brushstrokes that go far beyond the late manner of Titian  and announce the last stage in Velazquez�s development. This portrait was  copied innumerable times and won him immediate and lasting renown in  Italy. In his last years he created his masterpiece. Las Meninas (The Maids  of Honour, 1656). In this casual scene, the artist is shown painting the  king and queen in the presence of the infanta Margarita and her atten�  dants; the nearly life-size figures are painted in more or less detail accord�  ing to their relation to the central figure of the infanta and to the source  of light, creating a remarkable illusion of reality never surpassed by  Velazquez or any other artist of his age. He is universally acknowledged  as one of the giants of Western art.</p><p>Velde, Henri van de (b. April 3, 1863, Antwerp, Belg.�d. Oct. 25,  1957, Zurich, Switz.) Belgian architect, designer, and teacher. Sharing the  philosophy of William Morris and the Arts and Crafts Movement, van de  Velde believed in creating beautiful everyday objects. Increasingly occu�  pied by a philosophy of total design, in 1895 he designed Bloemenwerf,  a house for his wife and himself outside of Brussels for which he also  designed all the interiors and furnishings. In 1896 he designed furniture  and interiors for the Paris art galleries of Samuel Bing; because of the  curving, delicate nature of these designs, van de Velde is credited with  bringing the Art Nouveau style to Paris. (Van de Velde himself is gener�  ally associated with the Jugendstil movement, which was the German  branch of Art Nouveau design.) In Weimer in 1902 he reorganized the  arts and crafts school and the academy of fine art and thus laid the foun�  dations for the amalgamation of the two bodies into the Bauhaus in 1919.  He designed his best-known structure, the curving, sinuous Werkbund  Theatre in Cologne, in 1914. His later work includes the Belgian pavil�  ions at the international exhibitions in Paris (1937) and New York (1939).  He also created graphic design work, generally in the curvilinear Art  Nouveau style, and he spread his ideas through lecturing and teaching.</p><p>Velde Vvel-doV Willem van de, the Elder (b. 1611, Leiden,  Neth.�d. December 1693, London, Eng.) Dutch marine painter. He sailed  with the Dutch fleet and painted its engagements with the English. Set�  tling in England in 1672, he continued to paint marine subjects, often in  collaboration with his son, Willem the Younger (1633-1707), who became  the foremost marine painter of his time. The latter was appointed court  painter by Charles II in 1677 and was commissioned to paint England�s  naval battles; many of his works are housed in London�s National Mari�  time Museum.</p><p>Velikovsky V.ve-li-'kof-skeV Immanuel (b. June 10, 1895, Vitebsk,  Russia�d. Nov. 17, 1979, Princeton, N.J., U.S.) Russian-born U.S. writer.  He earned various degrees in Moscow and Edinburgh before moving to  the U.S. in 1939. In his first book, Worlds in Collision (1950), he hypoth�  esized, relying on legends of ancient peoples, that Venus and Mars had  approached Earth closely c. 1500 bc, disturbing its rotation, axis inclina�  tion, and magnetic field. His claim was widely discredited by astrono�  mers, and the book�s publication caused U.S. scientists to threaten a  boycott of his publisher. Later works set out other controversial theories  about ancient history and catastrophic occurrences.</p><p>Velociraptor \v3-Ta-s9-,rap-tor\ Genus of clawed theropod dinosaur  (family Dromaeosauridae) that flourished in central and eastern Asia dur�  ing the Late Cretaceous Epoch (99-65 million years ago). It was related  to an Early Cretaceous (144-99 million years ago) North American genus,  Deinonychus. Both genera had a sickle-shaped claw on each foot and ossi�  fied tendon reinforcements in the tail that enabled them to keep their bal�  ance while striking and slashing at prey. Swift, agile predators of small  herbivores, they grew up to 6 ft (1.8 m) long and weighed up to 100 lb  (45 kg).</p><p>velocity Quantity that designates the speed and direction in which a  body moves. It can be represented graphically by an arrow (pointing in  the direction of the motion), the length of which is proportional to the  magnitude, or speed. For an object in circular motion, the direction at any  instant is tangential to the circle at that point, and so is perpendicular to  the radius at that point. The instantaneous speed of a vehicle, such as an  automobile, can be determined by a speedometer, or mathematically by  differential calculus. The average speed is the ratio of the distance traveled  in any given time interval divided by the time taken.</p><p>velvet Fabric having a short, dense pile, used in clothing and uphol�  stery. Velvet is made in the pile weave (see weaving), of silk, cotton, or</p><p>synthetic fibres and is characterized by a soft, downy surface formed by  clipped yarns (see shearing). Its �wrong� side is smooth and shows the  weave used. Velvets can be made water-repellent and crush-resistant.  They are also occasionally patterned or embossed.</p><p>vena cava \ l ve-n3- , ka-vo\ Either of two major veins that deliver oxygen-  depleted blood to the right side of the heart. The superior vena cava drains  the upper body, and the inferior vena cava drains the lower body.

The Venda, today numbering  more than 750,000, were the last of the peoples in the area to come under  European control. Agriculture dominates their economy; cattle raising has  increased in importance. Venda chiefs are traditionally custodians of the  land, while local headmen permit household groups to occupy and work  tracts of land.</p><p>Venda Former black enclave, northeastern South Africa. Located near  the Zimbabwe border, it attracted the Venda people, who migrated into  the region in the early 1700s from what is now Zimbabwe. It was annexed  to Transvaal in 1898 and was a distinct administrative unit within South  Africa when the country designated it a homeland for Venda-speaking  people in 1962. The territory was granted partial self-government in 1973  and became an independent republic in 1979; it never received interna�  tional recognition. After apartheid was abolished, Venda was reincorpo�  rated into South Africa in 1994 as part of the newly created Northern (now  Limpopo) province.</p><p>Vendee \va n -'da. Wars of the (1793 -96) Insurrections in the west  of France during the French Revolution. In the religious and impoverished  area known as the Vendee, discontent with the new government grew after  it instituted strict controls over the Catholic church (1790). An uprising  began in opposition to the conscription acts (1793) and spread through�  out the region, where peasants were joined by royalists to form the Catho�  lic and Royal Army. Led by the nobleman Frangois Charette de La Contrie  (1763-1796), the Vendean army of 65,000 occupied several towns, but  was defeated at Cholet by government troops and forced to retreat. After  further defeats at Le Mans (about 15,000 rebels killed) and at Savenay,  the general warfare ended in December 1793. Vicious reprisals by the  government provoked further resistance, until an amnesty was announced  (1794) and the Vendee was granted freedom from conscription (1795).  Charette joined a British-backed landing of exiled French nobles in Brit�  tany (1795), but after their defeat and his execution (1796) the counter�  revolutionary struggle ended.</p><p>Vendemiaire \va n -da-'myer\ First month in the French republican cal�  endar. It also was the name given to the event of 13 Vendemiaire of the  year IV (Oct. 5, 1795), when Gen. Napoleon Bonaparte led the French  Revolutionary troops that stopped an insurrection of Parisians as they  marched against the government.</p><p>vending machine Machine from which various goods may be pur�  chased, either with coin, paper currency, or electronic payment card. The  first vending machines were introduced in 18th-century England to sell  snuff and tobacco. From the late 19th century they have been widely used  in many countries. Vending service is typically provided by a company  that owns the machines and places them in businesses, schools, and the  like. These operators provide the products and service either without cost  to the owner of the premises on which a machine is located or in return  for a servicing charge.</p><p>Vendsyssel-Thy Vven-.sue-sol-'tuA Island, northern end of Jutland,  Denmark. It is known as Vendsyssel in the east and Thy in the west. The  Limfjorden separates it from the mainland, to which it was attached until  1825, when water erosion cut a channel through the narrow isthmus at  Thyborpn. It has an area of 1,809 sq mi (4,686 sq km). Frederikshavn,  the main port, lies on the east coast facing Goteborg, Swed. The island is  a holiday resort.</p><p>veneer Extremely thin sheet of rich-coloured wood (such as mahogany,  ebony, or rosewood) or precious materials (such as ivory or tortoiseshell)  cut in decorative patterns and applied to the surface of a piece of furni�  ture. Though veneering was practiced in Classical antiquity, its use lapsed  in the Middle Ages. It was revived in the 17th century, reaching its apo�  gee in France and spreading from there to other European countries. The  considerable craftsmanship involved in artistic veneering is most evident  in the 18th and early 19th centuries, when Thomas Chippendale, George</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>1994 I Venera &#x25BA; Venice</p><p>Hepplewhite, and Thomas Sheraton used mahogany and satinwood veneers.

Venera 2 flew to within  25,000 mi (40,000 km) of Venus in 1966; a few days later, Venera 3  crash-landed on its surface, becoming the first spacecraft to strike another  planet. Later missions analyzed Venus�s atmosphere, made soft landings,  detected certain long-lived radioactive isotopes (chiefly uranium and tho�  rium), sent back the first close-up photographs of the planet�s surface,  and mapped the surface of the northern hemisphere with radar (by Ven�  era 15 and 16, the last two of the series).</p><p>Venetian glass Variety of glassware made in Venice from the 13th  century to the present. In the 15th  century efforts were concentrated on  the perfection of cristallo (clear  glass that approximated rock crystal  in appearance). By the 16th century  Venetian glassmakers mastered tech�  niques of adding colour and of  removing the smoky tint produced  by metal in the glass material. These  and other secrets were guarded  closely, and defecting workers were  severely punished. But eventually  many Venetian glassmakers did  defect, and the techniques became  common knowledge in France, Ger�  many, The Netherlands, and  England.</p><p>Venetian school Renaissance  artists of Venice whose work is char�  acterized by a love of light and  colour. Jacopo Bellini was the first in  this influential line, followed by his  son Gentile Bellini, the instructor of  Venice�s great High Renaissance  painters, including Giorgione and  Titian. In due course Titian became  the dominant force in Venetian paint�  ing, and his rich colours and paint�  erly technique were widely imitated.</p><p>Other 16th-century masters included Veronese, known for his vast, bril�  liantly coloured, pageantlike canvases, and Tintoretto, who combined the  Mannerists� rapidly receding diagonals and dramatic foreshortenings with  the Venetian love of light as a means of defining form and heightening  drama. Giovanni Battista Tiepolo was the last important Venetian figure  painter and one of the greatest artists of the Rococo period.</p><p>Veneto \'ve-na-,to\ Region (pop., 2001 prelim.: 4,490,586), northern  Italy. It covers an area of 7,090 sq mi (18,364 sq km); its capital is Ven�  ice. Bordered by Austria, the Adriatic Sea, and Lake Garda, the northern  part is mountainous, while the southern part consists of a fertile plain.  Parts were under Roman rule c. 2nd-lst centuries bc (see Padua and  Verona) and later were subject to the Lombards. In the Middle Ages, sev�  eral city-states gained importance, but most subsequently were subject to  Venice. The area began to slip from Venetian hold after the French Revo�  lution, and in the early 19th century Veneto came under Austrian rule. It  was returned and joined to Italy in the 1860s. Agriculture is an economic  mainstay, and industrial works are found around Veneto�s major cities.</p><p>Venezia Tridentina See Trentino-Alto Adige  Veneziano, Domenico See Domenico Veneziano</p><p>Venezuela officially Bolivarian Republic of Venezuela Coun�  try, northern South America.

The highest waterfall in the  world, Angel Falls, is in Venezuela. Lakes  include Maracaibo and Valencia. Principal  mineral resources are petroleum and natural gas. Other mineral reserves  include iron, bauxite, gold, and diamonds. Industries include steel, chemi�  cals, textiles, and oil refining. Agricultural products�notably sugar, cof�  fee, com, bananas, and cacao�are important. Venezuela is a republic with  a unicameral legislature; its head of state and government is the president.  Venezuela has been inhabited by indigenous peoples for millennia. In  1498 Christopher Columbus sighted it; European explorers named the  region Venezuela (Spanish: �Little Venice�) after observing local Indian  houses on stilts along the shores of Lake Maracaibo. A Spanish mission�  ary established the first European settlement at Cumana c. 1523. In 1717  it was included in the Viceroyalty of New Granada. Venezuelan Creoles  led by Francisco de Miranda and Simon Bolivar spearheaded the South  American independence movement, and, though Venezuelans had  declared independence from Spain as early as 1797, it was not assured  until the last royalist forces surrendered in 1823. Military dictators gen�  erally ruled the country from 1830 until the overthrow of Marcos Perez  Jimenez in 1958. A new constitution adopted in 1961 marked the begin�  ning of democracy. As a founding member of OPEC (Organization of  Petroleum Exporting Countries), Venezuela enjoyed relative economic pros�  perity from oil production during the 1970s, but its economy has remained  dependent on fluctuations in the world petroleum market. The govern�  ment of Hugo Chavez promulgated a new constitution in 1999, the year  in which a devastating rainstorm killed thousands in and around  Caracas�one of the deadliest events in Venezuelan history. Despite an  increase in oil prices in the early 21st century, the country experienced  great political turmoil.</p><p>Venice Italian Venezia \va-'net-sya\ City (pop., 2004 est.: 271,663),  capital of Veneto region, northern Italy. Built on a lagoon, Venice encom�  passes some 118 islands, the whole 90-mi (145-km) perimeter of the  lagoon, and two industrial mainland boroughs. Refugees from northern  invasions of the mainland founded settlements in the 5th century ad that  were built uniquely on islands as protection against raids. Venice was a vas�  sal of the Byzantine Empire until the 10th century. Beginning with control  of a trade route to the Levant, Venice emerged from the Fourth Crusade  (1202-04) as ruler of a colonial empire which included Crete, Euboea, the  Cyclades, the Ionian Islands, and footholds in Morea and Epirus. In 1381 it  defeated Genoa after a century-long struggle for commercial supremacy in  the Levant and eastern Mediterranean. In the 15th century, with the acqui�  sition of neighbouring regions, the Republic of Venice became an extensive  Italian state. It gradually lost its eastern possessions to Ottoman Turks, with</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Venice &#x25BA; Venus</p><p>1995</p><p>whom Venice fought intermittently from the 15th to the 18th century; it  gave up its last hold in the Aegean in 1715. The republic dissolved and the  territory was ceded to Austria in 1797. Incorporated into Napoleon�s King�  dom of Italy in 1805, it was restored to Austria in 1815. A revolt against  Austria (1848^-9) eventually resulted in Venice being ceded to Italy in  1866. It suffered little damage during World War II, but flooding along its  many miles of canals caused severe damage in 1966. The waters of the  lagoon rise and flood the city on a regular basis, complicating efforts to  preserve its architecture, which includes Italian, Arabic, Byzantine, and  Renaissance forms. There are some 450 palaces and homes of major his�  toric importance in Venice. Notable among its 400 bridges is the Bridge of  Sighs (built c. 800) and among its churches St. Mark's Basilica. Most of the  city�s workers find employment in tourism and related industries, though  Venice also plays a key market role within the vibrant economic system of  the Veneto region.</p><p>Venice, Gulf of Northern section of the Adriatic Sea. It extends east�  ward for 60 mi (95 km) from the Po River delta, Italy, to the coast of Istria.  Marshes, lagoons, and sandspits border the gulf�s shores as far as Trieste,  Italy. A northeast wind, called the bora, causes rough seas and creates  shipping hazards in the gulf.</p><p>Venice, Peace of (1177) Agreement in which Holy Roman Emperor  Frederick I Barbarossa acknowledged Alexander III as the true pope. Fred�  erick�s decisive defeat by the Lombard League at the Battle of Legnano  (1176) had obliged him to abandon his Italian campaign and sign a truce.  In the Peace of Venice, Frederick agreed to withdraw support from the  antipope and to restore church property he had seized. He received the  kiss of peace from the pope in front of St. Mark�s.</p><p>Venice, Treaty of (1201) Treaty negotiated between crusaders in the  Fourth Crusade and Enrico Dandolo of Venice to provide transport for  85,000 marks.

It was founded in 1895 as the International Exhibition of Art  of the City of Venice to promote �the most noble activities of the mod�  ern spirit without distinction of country.� The first Biennale, which  achieved worldwide prestige, included artists from 16 nations; the com�  mittee included Edward Burne-Jones, Gustave Moreau, and Pierre Puvis de  Chavannes. After World War II it became the leading showplace for the  international avant-garde. Usually held in the summer months, it attracts  many tourists and visitors.</p><p>Venizelos \,ven-y9-'ze-l6s\, Eleutherios (Kyriakos) (b. Aug. 23,  1864, Moumies, Crete, Ottoman Empire�d. March 18, 1936, Paris,  France) Greek revolutionary leader. Son of a Cretan revolutionary, he  served in the government of autonomous Crete as minister of justice  (1899-1901), then led an insurrection that forced the autocratic high com�  missioner to leave Crete (1905). In Athens, he led the Military League  opposition group and effected the union of Crete with Greece. As premier  of Greece (1910�15) he helped form the Balkan League. During the Bal�  kan Wars, his policies doubled Greece�s area and population. In World  War I he supported the Allies; he resigned when opposed by the pro-  German King Constantine, led the opposition that forced the king into  exile, and again became premier (1917�20), aligning Greece with the  Allies and successfully protecting Greek interests at the Paris Peace Con�  ference. He served three more stints as premier (1924, 1928-32, 1933),  but he was forced into exile when the monarchy was restored in 1935.</p><p>venom Poison secreted by an animal, produced by specialized glands  often associated with spines, teeth, or stings. It may be primarily for para�  lyzing or killing prey or may be purely defensive. Some venoms also  function as digestive fluids. Their effects can range from localized skin  inflammation to almost immediate death; they include nervous-system  excitation (cramps, vomiting, convulsions) or depression (paralysis, respi�  ratory or cardiac depression or arrest), hemorrhage, red-blood-cell break�  down, circulatory collapse, and allergic reactions (including hives and  inflammation). Many major groups of animals contain venomous species:  snakes (cobras, mambas, vipers, pit vipers); fish (stingrays, spiny sharks, cer�  tain catfish, puffers); lizards (Gila monsters, beaded lizards); scorpions;  spiders (black widow spiders, brown recluse spiders); social insects (bees,  wasps, some ants); and marine invertebrates (sea anemones, fire corals, jel�  lyfish, sea urchins). See also antidote.</p><p>ventilating Natural or mechanically induced movement of fresh air into  or through an enclosed space. The hazards of poor ventilation were not  clearly understood until the early 20th century. Expired air may be laden  with odors, heat, gases, or dust. Mechanical ventilation systems typically  include a fan and filter to remove particles. A mechanically powered inlet  of air, when combined with a natural exhaust, tends to cause a slight posi�  tive pressure within an enclosed space, so that the air leakage is outward.  A mechanical exhaust with a natural air inlet causes a slight negative  pressure, so that air moves inward. Such systems are often used to con�  fine fumes or smells to a particular area of a building (e.g., laboratories,  kitchens, bathrooms) and exhaust them to the outside.</p><p>ventricular fibrillation Uncoordinated contraction of the muscle  fibres of the heart�s ventricles (see arrhythmia). Causes include heart  attack, electric shock, anoxia, abnormally high potassium or low calcium  in the blood, and digitalis or epinephrine poisoning (see drug poisoning).  Death soon follows if circulation is not restored with electric shocks  (defibrillation) or drugs supplemented by chest compressions (as in car�  diopulmonary resuscitation). See also atrial fibrillation.</p><p>ventriloquism Art of �throwing� one�s voice in such a way that the  sound seems to come from a source other than the speaker. A dummy or  doll is commonly used to assist in the deception, with the ventriloquist  moving the dummy�s mouth while speaking through closed lips. Ventrilo�  quists date from ancient times and include Eurycles of Athens. Such  peoples as the Maoris, Zulus, and Eskimos are adept ventriloquists. The  art was long a feature of puppet shows as well as of variety entertainment  such as vaudeville. Notable ventriloquists included Edgar Bergen in the U.S.  and Robert Lamouret in France.</p><p>Ventris Vven-trosV Michael (George Francis) (b. July 12, 1922,  Wheathampstead, Hertfordshire, Eng.�d. Sept. 6, 1956, near Hatfield,  Hertfordshire) British architect and cryptographer. At age 14 he heard a lec�  ture on the continuing mystery of Linear B script (see Linear A and Linear B)  and resolved to decipher it. In 1952 he determined that Linear B was Greek  in its oldest known form, dating from c. 1400-1200 bc. He collaborated  with John Chadwick (1920-98) on Documents in Mycenaean Greek  (1956), published a few weeks after his own death in an auto accident.</p><p>Venturi, Robert (Charles) (b. June 25, 1925, Philadelphia, Pa., U.S.)  U.S. architect. He studied at Princeton University and in Rome at the  American Academy. After working with Eero Saarinen and Louis Kahn, he  formed a partnership with his wife, Denise Scott Brown, and John Rauch.  His philosophy, set forth in the influential books Complexity and Contra�  diction in Architecture (1966) and Learning from Las Vegas (1972), called  for openness to the multiple influences of historical tradition, ordinary  commercial architecture, and Pop art. He had such a profound impact on  younger architects who were beginning to find similar constraints and  limitations in the Modernist architectural aesthetic, that he became the  unofficial dean of the postmodern movement in architecture. His buildings  often exhibit ironic humour. Important commissions include buildings for  Princeton and the University of Pennsylvania, the Seattle Art Museum  (1985-91), and the Sainsbury Wing of London�s National Gallery (1986�  91). He won the 1991 Pritzker Architecture Prize.</p><p>venturi \ven-'tur-e\ tube Short pipe with a constricted inner surface,  used to measure fluid flows and as a pump. The effects of constricted  channels on fluid flow were first investigated by Giovanni Battista Ven�  turi (1746-1822), but it was Clemens Herschel (1842-1930) who devised  the instrument in 1888. Fluid passing through the tube speeds up as it  enters the tube�s narrow throat, and the pressure drops. There are count�  less applications for the principle, including the carburetor, in which air  flows through a venturi channel at whose throat gasoline vapour enters  through an opening, drawn in by the low pressure. The pressure differ�  ential can also be used to measure fluid flow (see flow meter).</p><p>venue In law, the place or county in which the events giving rise to a  legal action take place and from which a jury may be drawn to try the  case. Venue statutes usually specify that a trial must take place in the dis�  trict that has jurisdiction over the matter. The grounds for a change of  venue are also specified; they include fear of biased jurors due to media  coverage, danger of violence, and racial prejudice.</p><p>Venus Roman goddess of cultivated fields and gardens, later associated  with Aphrodite.

The planet Venus, originally the  star of Ishtar, came to be named for Venus through her association with  Ishtar. She has been a favourite subject in art since ancient times, nota�  bly in the statue known as Venus de Milo (c. 150 Bc)and in Sandro Bot�  ticelli�s painting The Birth of Venus (c. 1485).</p><p>Venus Second major planet from the Sun. Named for the Roman god�  dess, Venus is, after the Moon, the most brilliant natural object in the  night sky. Venus comes closer to Earth�about 26 million mi (42 million  km)�than any other planet. Its orbit around the Sun is nearly circular at  a distance of about 67 million mi (108 million km) and takes 225 days;  its rotation, in retrograde motion, takes even longer (243 days). As viewed  from Earth, Venus undergoes phase changes similar to the Moon�s, going  through one cycle of phases in 584 days. It is seen only near sunrise or  sunset and has long been known as both the morning star and the evening  star. Venus is a near twin of Earth in size and mass but is completely  enveloped by thick clouds of concentrated sulfuric acid droplets. Its sur�  face gravity is about 90% that of Earth. Its atmosphere is over 96% car�  bon dioxide, with a pressure about 95 times Earth�s. The dense  atmosphere and thick cloud layers trap incoming solar energy so effi�  ciently that Venus has the highest surface temperature of any of the Sun�s  planets, more than 860 �F (460 �C). Radar imaging indicates that the sur�  face is dry and rocky, consisting mostly of gently rolling plains, broad  depressions, and two large elevated regions analogous to continents on  Earth; Venus also has impact craters, extensive lava fields, and massive  shield volcanos. The interior is thought to be similar to that of Earth, with  a metal core, a dense rocky mantle, and a less-dense rocky crust. Unlike  Earth, Venus has no intrinsic magnetic field.</p><p>Venus's-flytrap or Venus flytrap Flowering perennial plant (Dio-  naea muscipula ), sole member of its  genus, in the sundew family, notable  for its unusual habit of catching and  eating insects and other small ani�  mals (see carnivorous plant). Native  to a small region of North and South  Carolina, it is common in damp,  mossy areas. Growing from a bulb�  like rootstock, the plant bears hinged  leaves with spiny teeth along their  margins and a round cluster of small  white flowers at the tip of an erect  stem 8-12 in. (20-30 cm) tall. When  an insect alights on a leaf and stimu�  lates its sensitive hairs, the leaf snaps  shut in about half a second. Leaf  glands secrete a red sap that digests the insect�s body and gives the entire  leaf a red, flowerlike appearance. After 10 days of digestion, the leaf  reopens. The trap dies after capturing three or four insects.</p><p>Veracruz V.ver-o-'kriizV in full Veracruz Have City (pop., 2000:  411,582) and port on the Gulf of Mexico, east-central Veracruz state, east-  central Mexico. Hernan Cortes founded La Villa Rica de la Veracruz as  the first Mexican municipality in 1519, but the site was twice abandoned  because of its unhealthy conditions; the present city dates from c. 1600.  As the chief link between colonial Mexico and Spain, Veracruz prospered  as a port and became the most �Spanish� of Mexican cities. It was attacked  and captured repeatedly, first by privateers, then by French and U.S. forces  (see Veracruz incident). It was renamed Veracruz Llave in honour of Gen.  Ignacio de la Llave, governor of Veracruz state (1857-60). Both the 1857  and 1917 Mexican constitutions were proclaimed there. A revolt against  Pres. Francisco Madero occurred there in 1912.

The state�s low, sandy gulf area rises inland to a central plateau,  where the volcano Citlaltepetl, Mexico�s highest peak, reaches 18,406 ft  (5,610 m) high. The area was inhabited by pre-Columbian cultures, includ�  ing the Olmec. The first European landing was made by Hernan Cortes in  1519. A state since 1824, Veracruz has more than one-fourth of Mexico�s  petroleum reserves and several of the country�s refineries. Its economy is  supplemented by agriculture, forestry products, and manufacturing.</p><p>Veracruz incident (1914) Occupation of Veracruz, Mex., by U.S.  marines. In April 1914, after the crew of a U.S. ship that had anchored in</p><p>Tampico was briefly detained for landing in a forbidden area, Pres. Wood-  row Wilson demanded an apology from the Mexican government. When  Mexican president Victoriano Huerta refused, Wilson sent a fleet to the  Gulf of Mexico. After learning of an arms shipment to Huerta from Ger�  many, Wilson ordered the port of Veracruz seized. By July the invasion  had caused 200 Mexican casualties and had enabled the rival Constitu�  tionalists under Venustiano Carranza (who had denounced the seizure by  the U.S.) to take over the government. Huerta was forced into exile, and  the U.S. marines were withdrawn on November 14.</p><p>Veralden-radien Vva-a-.ral-dan-'ra-de-enN Deity believed by the Sami  to be the closest to the starry heaven. Because he is associated with the  pillar supporting the heavens, he is also responsible for the continuance  of life. He imparts the souls of unborn children to Madderakka and takes  the souls of the departed to the realm of the dead. He was also the sub�  ject of a phallic cult; each year the genitalia and blood of a bull reindeer  were smeared on his statue. His worship has many Scandinavian features,  which has led scholars to seek his origin in Norse mythology.</p><p>verbena Xvor-'be-nsX Plant genus ( Verbena ) that contains about 250  species, almost all of them native to the New World tropics and subtrop�  ics. Two species are indigenous to the Old World. The familiar garden  verbena ( V. hortensis, or V. hybrida ) is a creeping plant that has square  stems and bears flat heads of phloxlike flowers, in a wide range of colours.  Many U.S. species of Verbena are low-growing, small-flowered, some�  what weedy plants more commonly called vervains. The shrub lemon  verbena (Aloysia triphylla ), notable for its fragrant oil, is a member of the  verbena, or vervain, family (family Verbenaceae), which contains more  than 2,600 species in about 100 genera. Members of the family have  opposite or whorled leaves that are usually undivided. The flowers, in  spikes or clusters, usually consist of a tube flaring into four or five almost  equally cut lobes. The family also includes teak.</p><p>Vercingetorix \ l v3r-s9n- , je-t3-,riks\ (d. 46 bc) Chieftain of the Gallic  tribe of the Arvemi. Julius Caesar had almost subjugated Gaul (see Gal�  lic Wars) when Vercingetorix, acclaimed king of his people, led the Gauls  against him (52 bc), using guerrilla tactics and picking battle sites favour�  able to his own forces. After winning a major victory at Gergovia, his  later attack on the Roman army failed; besieged at Alesia, he was forced  to surrender. Taken to Rome in chains, he was displayed in Caesar�s tri�  umph and executed six years later.</p><p>Verdi \'ver-de\, Giuseppe (Fortunato Francesco) (b. Oct. 9/10,  1813, Roncole, near Busseto, duchy of Parma�d. Jan. 27, 1901, Milan,  Italy) Italian composer. He was the son of an innkeeper, and he showed  talent early. While earning a living as an organist, he began to write operas  in Milan; in 1839 his Oberto was successfully performed at La Scala, and  it initiated Verdi�s long association with the publisher Giulio Ricordi. His  next opera, Un giorno di regno ( 1840), was a failure. Much worse, Verdi�s  two young daughters and his wife died. He overcame his despair by com�  posing Nabucco (1842); it was a sensational success and was followed by  the equally successful I Lombardi (1843). For the rest of the decade he  wrote a hit opera every year. Rejecting the prevailing structure of Italian  opera�a patchwork of open-ended scenes and inserted arias, duets, and  trios�he began conceiving of an opera as a series of integrated scenes,  then as unified acts. Specializing in stories in which people�s private and  public lives come into conflict, he produced a series of masterworks,  including Rigoletto (1851), II trovatore (1853), La traviata (1853), Don  Carlos (1867), and Aida (1871). A fervent nationalist, he was regarded as  a great national figure. After composing his Requiem (1874), he retired, but  when Ricordi brought him together with the poet and composer Arrigo  Boito, initially to revise Simon Boccanegra, their mutual esteem led to the  two great operas of Verdi�s old age, Otello (1886) and Falstaff{ 1890).</p><p>Verdigris Vvor-ds-grosX River River, southeastern Kansas and north�  eastern Oklahoma, U.S. It rises in east-central Kansas and flows south  across the Oklahoma border, emptying into the Arkansas River northeast  of Muskogee, Okla.

As part of its strategy of  war by attrition, Germany selected the fortress of Verdun as the site it  believed France would defend to the last man. After a massive bombard�  ment, the Germans advanced with little opposition for four days before  the reinforced French army under Philippe Petain slowed their advance. For  two months the hills west of the Meuse River and north of Verdun were  bombarded, attacked, and counterattacked.

It marked a first  stage in the dissolution of Charlemagne�s empire and a step toward the  formation of the modem countries of western Europe. The treaty was  signed following three years of civil war between the three brothers.  Lothar I received the imperial title and Francia Media, which included  much of Italy as well as parts of several other present-day European  countries. Louis the German received Francia Orientalis, the land east of  the Rhine River, and Charles II (the Bald) received Francia Occidentalis,  the remainder of modem France.</p><p>Verga \'var-ga\, Giovanni (b. Sept. 2, 1840, Catania, Sicily�d. Jan.  27, 1922, Catania) Italian writer, the most important of the verismo (real�  ist) school of novelists. Bom to a family of landowners, Verga left Sicily  for the mainland, where he remained until 1893. There he developed a  writing style noted for its terse accuracy and intensity of feeling. His best  works include the short stories of Little Novels of Sicily (1883), the nov�  els The House by the Medlar Tree (1881) and Mastro-Don Gesualdo  (1889), and the play Cavalleria rusticana (1884; �Rustic Chivalry�),  which became immensely popular when it was adapted as an opera by  Pietro Mascagni. His influence on the post-World War II generation of  Italian Neorealist writers was particularly marked (see Neorealism).</p><p>Vergennes \ver-'zhen\, Charles Gravier, count de (b.

As Louis XVI �s minister of foreign affairs  (1774-87), he advocated French financial and military support for the  colonists in the American Revolution, concluded an alliance with them  (1778), and helped negotiate the Treaty of Paris (1783). He also worked  to establish a stable balance of power in Europe by mediating the peace  in the War of the Bavarian Succession.</p><p>Verghina or Vergina \ver-�ge-na\ Archaeological site and ancient  capital of Macedonia, northern Greece.

Nov. 27, 1916, Rouen, France) Belgian poet.  He wrote in French, producing more than 30 collections of poetry out�  standing for its strength and range. His first book, Les Flamandes (1883),  contains violently naturalistic poems. Later he began to show a growing  concern for social problems. His major works include The Sunlit Hours  (1896), The Evening Hours (1911), and Belgium�s Agony (1915). His three  main themes are Flanders, human energy, and his tender, understanding  love for his wife. He also published plays and books on art. He was one  of the group in Brussels who brought about the literary and artistic renais�  sance of the 1890s.</p><p>verifiability principle Criterion of meaningfulness associated with  logical positivism and the Vienna Circle. Moritz Schlick�s formulation �The  meaning of a [declarative sentence] is the method of its verification� was  close to the view held in pragmatism, and later in operationalism, that an  assertion has factual meaning only if there is a difference in principle,  open to test by observation, between the affirmation and the denial of the  assertion. Thus, the statements of ethics, metaphysics, religion, and aes�  thetics were held to be meaningless. The verifiability criterion of mean�  ingfulness was in part inspired by Albert Einstein�s abandonment of the  ether hypothesis and the notion of absolute simultaneity.</p><p>Verlaine \ver-'len\, Paul (-Marie) (b. March 30, 1844, Metz,  France�d. Jan. 8, 1896, Paris) French lyric poet. After entering the civil  service, he was first associated with the Parnassian poets, contributing to  the first volume of the anthology Le Parnasse contemporain (1866). His  early collections, Poemes saturniens (1866), Fetes galantes (1869), La  Bonne chanson (1870), and Romances sans paroles (1874), show the  intense lyricism and musicality that would mark all his verse. His mar�</p><p>riage was shattered by his infatuation with Arthur Rimbaud, and the two  scandalized Paris with their behaviour in 1872-73. While in prison in  Belgium (1873-75) for shooting Rimbaud when the latter threatened to  leave him, he converted to Catholicism and probably composed the  famous �Art poetique,� adopted in 1882 by the poets of the Symbolist  movement. Sagesse (1880) expresses his religious faith and his emotional  odyssey. He later taught French and English; he spent his late years in  poverty, but just before his death he was sponsored for a major interna�  tional lecture tour. His Les Poetes maudits (1884; �The Accursed Poets�)  consists of short biographical studies of six poets, including Stephane  Mallarme and Rimbaud. He is regarded as the third great member (with  Charles Baudelaire and Mallarme) of the so-called Decadents.</p><p>Vermeer Wor-'mer, var-'mirV, Johannes (b. Oct. 31, 1632, Delft,  Neth.�d. Dec. 15, 1675, Delft) Dutch painter. His parents were tavern  keepers. He twice served as head of the Delft artists� guild but seems to  have depended on his activities as an art dealer to support his family. He  painted mainly interior genre subjects, depicting members of aristocratic  and upper-middle-class society. About half of these paintings show soli�  tary figures of women absorbed in some ordinary, everyday activity. His  interiors combine a microscopic observation of objects with a meticulous  depiction of the gradations of daylight on varied shapes and surfaces. His  masterpieces (none dated) include View of Delft, Young Woman Reading  a Letter, and Allegory of Painting, his most symbolically complex work.  He manages to be unique within a typically Dutch genre. Few foreign  influences can be sensed in his work. His work was not widely appreci�  ated in his own time, and he remained in obscurity until 1866, when  Theophile Thore celebrated his work and attributed 76 paintings to him;  later authorities have reduced the number to between 30 and 35, while  proclaiming him one of the greatest painters of all time.</p><p>Vermont State (pop., 2000: 608,827), northeastern U.S. One of the New  England states, it covers 9,614 sq mi (24,900 sq km); its capital is Mont�  pelier. On the north, Vermont borders Quebec, Can., on the south, Mas�  sachusetts, and on the west. New York. From the Canadian to the  Massachusetts border, the Connecticut River separates Vermont from New  Hampshire on the east. The Green Mountains extend through the centre  of Vermont. The highest point is Mount Mansfield, at 4,393 ft (1,339 m).  Most of the rivers drain into Lake Champlain. Settled originally by Abenaki  Indians, the region was explored by Samuel de Champlain, who in 1609  discovered the lake that now bears his name. The French established the  first permanent European settlement in 1666 on Isle La Motte. Both the  Dutch and the British established settlements in the 18th century, but the  area fell exclusively to the British in 1763. Disputes arose between New  York and New Hampshire concerning jurisdiction of the area; New Hamp�  shire had awarded grants to settlers. In 1770 Ethan Allen organized the  Green Mountain Boys to repel encroachers from western New York. In  1775, at the start of the American Revolution, Allen and his group, fight�  ing for the colonies, captured Fort Ticonderoga from the British. Ver�  monters created an independent republic in 1777, and in 1791 it became  the 14th U.S. state. In 1864, during the American Civil War, it was the site  of the only action north of Pennsylvania when a band of Confederates  raided St. Albans from Canada. Dairying and the mining of granite and  marble contribute to the economy. In the 1930s the first ski runs were  built, and by the 1960s a winter tourist industry had developed.</p><p>vernacular architecture Common domestic architecture of a region,  usually far simpler than what the technology of the time is capable of  maintaining.

Located on  the Adige River, it became a Roman colony in 89 bc and was the birthplace  of the poet Catullus. It was captured by the Goths after the fall of the  Roman Empire and was the site of Odoacer�s defeat by the Ostrogothic  king Theodoric in 489. It was occupied by Charlemagne in 774. Verona  came under the della Scala family (1260-1387), the era recalled in Wil�  liam Shakespeare�s Romeo and Juliet. It passed in 1405 to Venice, which  held it almost continuously until 1797, when it was ceded to Austria. It  became part of the Kingdom of Italy in 1866. It is noted for its ancient  Roman amphitheatre (1st century ad), now used for opera, and for  Romanesque and Gothic buildings.</p><p>Verona, Congress of (1822) Last of the meetings held by the Qua�  druple Alliance (Russia, Prussia, Austria, and Britain).

The congress agreed to  support France if it were attacked by Spain and authorized a French expe�  dition into Spain. However, Britain threatened to use its sea power to pre�  vent interference with the revolts in Spanish America. Increasing discord  caused a breakdown in the congress system begun by the alliance in 1815.</p><p>Veronese \ 1 ver-3-'na-se\ / Paolo orig. Paolo Caliari (b. 1528,  Verona, Republic of Venice�d. April 9, 1588, Venice) Italian painter. Son  of a stonecutter from Verona, he was apprenticed at 13 to a painter. After  1553, when he received the first of many commissions in Venice, he  became a major painter of the 16th-century Venetian school, a group of  Renaissance artists known for their splendid use of colour and pageant�  like compositions. His first works in Venice, ceiling paintings for the  Doges� Palace, employ skillful foreshortenings that make figures appear  to be floating in space. He decorated the villas and palaces of the Vene�  tian nobility and received many commissions for frescoes, altarpieces, and  devotional paintings, including numerous �suppers� (e.g., The Pilgrims of  Emmaus and Feast in the House of the Pharisees ) that allowed him to  compose large groups of figures in complex Renaissance architectural  settings. In decorating a villa built by Andrea Palladio at Maser (c. 1561),  he brilliantly interpreted its architectural structure, breaking through the  walls with illusionistic landscapes and opening the ceilings to blue skies  with figures from Classical mythology. Whimsical details in his Last Sup�  per (commissioned 1573) caused him to be summoned before the Inqui�  sition. Painters from the 16th century on were inspired by his use of colour  to express exuberance as well as to model form.</p><p>Verrazzano \,ver-3-'za-no\, Giovanni da (b. 1485, Tuscany,  Italy�d. 1528, Lesser Antilles) Italian navigator and explorer for France.  Educated in Florence, he moved to Dieppe, France, where he entered the</p><p>maritime service. In 1524 he was sent to find a westward passage to Asia  and reached North America. He explored the eastern coast from Cape Fear  northward and became the first European to explore the sites of present-day  New York Harbor and Narragansett Bay. He sailed along the coast to New�  foundland, then returned to France. He later led expeditions to Brazil  (1527) and to the Caribbean, where he was killed and eaten by cannibals.</p><p>Verres Vver-.ezV Gaius (b. c. 115�d. 43 bc) Roman magistrate. As  quaestor, Verres embezzled funds. He helped the governor of Cilicia,  Gaius Dolabella, plunder the province (80-78), and then he helped con�  vict Dolabella at Rome. He became praetor by bribery and abused his  power. As governor of Sicily (73-71) his corruption was extreme; he was  prosecuted so effectively by Cicero (70) that his lawyer had no reply. He  fled into exile but was murdered, perhaps at the orders of Mark Antony,  who then acquired his art collection.</p><p>Verrocchio \v3-'r6-ke-,6\, Andrea del (b. 1435, Florence�d. 1488,  Venice) Italian sculptor and painter.</p><p>Little is certain about his early life.</p><p>His most important works were  executed in his final two decades  under the patronage of the Medici in  his native Florence. His reputation as  a master spread early, and many  well-known artists studied at his stu�  dio, including Leonardo da Vinci and  Perugino; the young Leonardo prob�  ably painted an angel and part of the  distant landscape in Verrocchio�s  Baptism of Christ (c. 1470). Verroc�  chio�s reputation as one of the great  relief sculptors of the Renaissance  was established with his cenotaph in  the cathedral at Pistoia; while it  remained unfinished at his death and  was later changed by others, the  relief�s arrangement of figures into a  dramatically unified composition  anticipates the Baroque sculpture of  the 17th century. His bronze statue of  the military officer Bartolomeo Colleoni (commissioned 1483, erected in  Venice 1496) is one of the greatest equestrian statues of the Renaissance.</p><p>vers de societe \,ver-d3-s6s-ya-'ta\ French "society verse" Witty,  typically ironic, light verse, written with polish and ease of expression to  amuse a sophisticated audience. It has flourished in cultured societies,  particularly in court circles and literary salons, from the time of Anacreon  (6th century bc). Trivial subjects are treated in an intimate, witty manner,  and even when social issues form the theme, the light mood prevails. The  poetry of Ogden Nash, with its theme of self-ironic adult helplessness, is  a 20th-century example.</p><p>Versace, Gianni (b. Dec. 2, 1946, Reggio Calabria, Italy�d.

After working for several Italian ateliers in Milan,  in 1978 Versace established his own company, Gianni Versace SpA.  Throughout the 1980s and �90s he built a fashion empire by producing  ensembles that oozed sensuality and sexuality. He staged his seasonal  fashion shows like rock concerts at his lavish design headquarters in  Milan. On July 15, 1997, Versace was shot and killed on the front steps  of his Miami Beach, Fla., home, allegedly by the serial killer Andrew  Cunanan. At the time of his death, many believed that the designer�s  25-year career was at a peak.</p><p>Versailles \ver-'sl. Palace of Baroque palace southwest of Paris built  chiefly under Louis XIV. It was the principal residence of the French kings  and the seat of government from 1682 to 1789, with some 1,000 court�  iers and 4,000 attendants residing there. Originally a hunting lodge, it was  enlarged by Louis XIII and Louis XIV. Louis Le Vau (1612-70), with  Charles Le Brun and Andre Le Notre, began work on the palace in the  1660s. A masterpiece of formal grandeur intended as the visible expres�  sion of the glory of France, Versailles became the palatial ideal through�  out Europe and the Americas. Le Notre�s inventive arrangement of earth  forms, plantings, and fountains created vistas, terraces, formal gardens,  and wooded areas that celebrated the delights of both open and intimate  space.

It was negotiated pri�  marily by the U.S., Britain, and France, without participation by the war�s  losers. Germany was forced to accept blame for Allied losses and to pay  major reparations. Its European territory was reduced by about 10%, its  overseas possessions were confiscated, and its military establishment was  reduced. Although some of the treaty�s terms were eased in the 1920s, the  bitterness it created helped to foster an environment that led to the growth  of fascism in Italy and the rise of the Nazi Party in Germany. The treaty  also established the League of Nations, the International Labour Organiza�  tion, and the Permanent Court of International Justice (later the Interna�  tional Court of Justice).

In humans, it consists of 32-34 vertebrae, with different shapes and func�  tions in each of five regions: 7 cervical, in the neck (including the atlas  and axis, modified for free movement of the skull); 12 thoracic, in the  chest; 5 lumbar, in the lower back; 5 sacral (fused into the sacrum, part  of the pelvic girdle); and 3 to 5 coccygeal (vestigial tailbones fused into  the coccyx). The body of each vertebra is separated from its neighbours  by cushioning intervertebral disks of cartilage. Behind the body is a  Y-shaped vertebral (neural) arch with structures extending up and down  to form joints with the adjacent vertebrae and to the back and sides to  provide attachment points for muscles and ligaments. The spine supports  the torso and protects the spinal cord.</p><p>vertebrate Any animal of the chordate subphylum Vertebrata, which  includes the fishes, amphibians, reptiles, birds, and mammals. Vertebrates have  an internal skeleton formed of cartilage, bone, or both. The skeleton con�  sists of a backbone (vertebral column), which partly encloses a spinal  cord; a skull, which encloses the brain; and usually two pairs of limbs.  Nerves extending from the spinal cord and brain permeate the skin,  muscles, and internal organs. The muscular system consists primarily of  bilaterally paired masses attached to bones or cartilage. Skin and scales,  feathers, fur, or hair cover the outer surface.

A current  example is the oil industry, in which a single firm commonly owns the  oil wells, refines the oil, and sells gasoline at roadside stations. In hori�  zontal integration, by contrast, a company attempts to control a single  stage of production or a single industry completely, which lets it take  advantage of economies of scale but results in reduced competition.</p><p>vertigo \'v9r-t9-,go\ Feeling that one is spinning or that one�s surround�  ings are spinning around one, causing confusion and difficulty keeping  one�s balance, sometimes accompanied by nausea and vomiting. Vertigo  is normal after actual spinning, since inner-ear fluid continues to move  once the body has stopped, producing a mismatch between visual and  internal sensations. Lack of a stable visual reference point also contrib�  utes to this effect. Other causes include concussion and abnormalities of  the inner ear (e.g., labyrinthitis; see otitis), of the nerves that carry sig�  nals from it, or of the brain centers that receive them (e.g., stroke). Ver�  tigo is often confused with a feeling of faintness (see syncope), since both  are called dizziness.

The  soft, dense fur of many species has a speckled effect and bold markings  of white or bright colours. The face, chin, hands, and feet of C. aethiops  races are black.</p><p>Verwoerd ffsr-'viirtX, Hendrik (Frensch) (b. Sept. 8, 1901, Amster�  dam, Neth.�d. Sept. 6, 1966, Cape Town, S.Af.) Dutch-bom South Afri�  can prime minister (1958-66). He was taken to South Africa as an infant  by his missionary parents. After studying at the University of Stellen�  bosch, he became a professor there, and in 1937 he became editor of the  Afrikaner nationalist daily in Johannesburg. Appointed senator (1948) and  then minister of native affairs (1950), he was responsible for much of the  country�s new apartheid legislation. When he became prime minister in  1958, his apartheid program was strictly enforced, and he pushed through  legislation resettling blacks in reservations. His policies provoked dem�  onstrations, sometimes violent. In 1960 white voters approved his rec�  ommendation that South Africa leave the British Commonwealth, and his  dream of a republic came true. He was stabbed to death in the parlia�  mentary chamber by a parliamentary messenger of mixed descent.</p><p>Very Large Array (VLA) Radio telescope system consisting of 27  parabolic dishes. The most powerful radio telescope in the world, it has  been operated on the plains of San Agustin near Socorro, N.M., U.S., by  the National Radio Astronomy Observatory since 1980. Each dish is 82  ft (25 m) in diameter and can be moved independently by transporter  along rails laid out in an enormous Y pattern whose arms are about 13  mi (21 km) long. The radio signals received by the dishes are integrated  by computer, so the entire array acts as a single radio antenna (an inter�  ferometer). The VLA, which has a maximum angular resolution better  than a tenth of an arc second, has been responsible for producing many  of the most detailed radio images of quasars; galaxies; supernovas; and the  Milky Way Galaxy�s nucleus.</p><p>Vesalius Wo-'sa-le-osV Andreas Flemish Andries van Wesel (b.</p><p>Dec. 1514, Brussels�d. June 1564, island of Zacynthus, Republic of  Venice) Flemish physician. Bom into a family of physicians, he studied  medicine at the University of Paris. As a lecturer in surgery, he insisted  on dissecting corpses himself, instead of relying on untrained assistants,  to learn anatomy. Comparing his observations with ancient texts led him  to question the theories of Galen, at that time still considered authorita�  tive. Vesalius�s own complete textbook of human anatomy, the momen�  tous De humani corporis fabrica libri septem (1543; �Seven Books on  the Structure of the Human Body�), commonly called the Fabrica , was  the most extensive and accurate description of the human body that had  ever been published.</p><p>Vesey \'ve-ze\, Denmark (b. c. 1767, probably St. Thomas, Danish  West Indies�d. July 2, 1822, Charleston, S.C., U.S.) U.S. insurrection�  ist. Born into slavery, he was sold to a Bermuda slaver captain, with whom  he sailed on numerous voyages. They settled in Charleston, S.C., and  Vesey was allowed to purchase his freedom for $600 in 1800. After read�  ing antislavery literature, he determined to oppose the oppression of  slaves. He organized city and plantation blacks (up to 9,000 by some esti�  mates) for an uprising in which they would attack arsenals, seize arms,  kill all whites, bum Charleston, and free the slaves on surrounding plan�  tations. After a house servant warned the authorities, the insurrection was  forestalled and 130 blacks were  arrested; Vesey was tried and hanged  with 35 others.</p><p>Vespasian \ves-'pa-zh3n\ in full  Caesar Vespasianus Augus�  tus orig. Titus Flavius Vespa�  sianus (b. Nov. 17?, ad 9, Reate,</p><p>Latium�d. June 24, 79) Roman  emperor (69-79), founder of the Fla�  vian dynasty. Although of humble  birth, he won military glory in Brit�  ain and was awarded a triumph by  Claudius. In 63 he became proconsul  of Africa. He reconquered Judaea  except for Jerusalem (67-68) but  stopped fighting on the death of Nero  (68). After the murder of Galba, Ves�  pasian was proclaimed emperor by  the legions, while Vitellius claimed  the title in Cologne; Vespasian�s  forces soon defeated Vitellius in  Italy.

He increased provincial taxation to pay  for the deficits incurred by Nero and the civil wars, built the Temple of  Peace and began the Colosseum, and reformed the army and Praetorian  Guard. He ended the Jewish war (70) and the Rhineland revolt, adding  lands in Germany and Britain and pacifying Wales. He was succeeded by  his son Titus.</p><p>Vespucci \ves-'pu-che\, Amerigo (b. 1454, Florence�d. 1512,  Sevilla) Italian-born Spanish navigator and explorer of the New World.  He entered the Medici family business and in 1491 was sent to Sevilla,  where he helped outfit the ships for the expeditions of Christopher Colum�  bus. By 1496 he was manager of the Sevilla agency. He took part in two  (or four�the number is disputed) voyages to the New World; he was  navigator on a Spanish expedition (1499-1500) that probably discovered  the mouth of the Amazon River, and he led a Portuguese expedition  (1501-02) that discovered Guanabara Bay (Rio de Janeiro) and the Rio  de la Plata. In the accounts of the voyages (published 1507), the terms  America and New World were first used to describe the lands visited by  Amerigo Vespucci (in Latin, Americus Vespucius). As chief navigator for  the Sevilla-based Commercial House for the West Indies (from 1508), he  prepared maps of newly discovered lands from data supplied by ships�  captains.</p><p>Vesta In Roman religion, the goddess of the hearth, identified with the  Greek Hestia. Because maintaining a  hearth fire was important in ancient  times, she was worshiped in every  household. Her state worship was  elaborate: her temple in Rome had a  perpetual fire that was attended by  the Vestal Virgins. The fire was offi�  cially extinguished and renewed  annually on March 1st; its extinction  at any other time was viewed as a  portent of disaster to Rome.</p><p>Vestal Virgin In Roman religion,  any of six priestesses, representing  the daughters of the royal house,  who tended the state cult of Vesta.</p><p>Chosen between the ages of 6 and  10, they served for 30 years, during  which time they had to remain vir�  gins; violation of the vow of chastity was punishable by burial alive. Their  duties included tending the perpetual fire in the Temple of Vesta, fetch�  ing water from a sacred spring, preparing ritual food, caring for objects  in the temple�s inner sanctuary, and officiating at the public worship of  Vesta. They enjoyed many honours and privileges, including emancipa�  tion from their fathers� rule.</p><p>Vestris, (Marie-Jean-) Auguste (b. March 27, 1760, Paris, Fr.�d.

His most celebrated pupil was his son Auguste  Vestris.</p><p>Vesuvius Active volcano, eastern side of the Bay of Naples, southern  Italy. It originated about 200,000 years ago; its current height of 4,198 ft  (1,280 m) has varied considerably after each of its major eruptions; in  1900 it was 4,275 ft (1,303 m) high; in 1906, 3,668 ft (1,118 m) high;  and in the 1960s, 4,203 ft (1,281 m) high. The cone is half-encircled on  the northern side by Mount Somma, part of the wall of a large crater in  which the present cone has formed. There have been numerous destruc�  tive eruptions; in ad 79 Pompeii and Hercuianeum were destroyed, and in  1631 about 3,000 people were killed. The last major eruption occurred in  1944. More than two million people live in the area of Vesuvius, whose  fertile slopes are covered with vineyards and orchards.</p><p>vetch Any of about 150 species of herbaceous plants in the genus Vicia  of the pea family (see legume).

Originally  called Armistice Day, it began as a  commemoration of the ending of World War I on Nov. 11, 1918. After  World War II it was recognized as a day to pay tribute to all service mem�  bers, and in 1954 it was designated as Veterans Day. It is usually observed  with parades, speeches, and flowers placed on military graves and memo�  rials. The holiday is called Remembrance Day in Canada and Remem�  brance Sunday (on the Sunday nearest to November 11) in Britain.</p><p>veterinary science Medical field dealing with animals and with dis�  eases that are contagious between animals and humans. It was a medical  specialty in ancient Egypt and Babylonia but went through a period of  virtual nonexistence in medieval Europe before reappearing in the mid-  18th century with the founding of the first veterinary schools. Veterinar�  ians practice internal medicine, surgery, and preventive medicine, using  the same techniques used on humans. Many specialize in either small ani�  mals (pets) or large ones (livestock); a few specialize in wild animals.</p><p>Viagra First oral drug for male impotence, generic name sildenafil.  Before the FDA approved Viagra in 1998, impotence was treated with  surgical implants, suppositories, pumps, and drugs injected into the penis.  Taken as a pill shortly before sexual intercourse, Viagra selectively dilates  blood vessels in the penis, improving blood flow and allowing a natural  sexual response. It works in about 70% of cases; it should not be used by  anyone taking nitroglycerin or with heart problems, hypotension, hyper�  tension, recent stroke, or certain eye disorders.</p><p>viatical settlement Arrangement by which a terminally ill patient�s  life-insurance policy is sold to provide funds while the insured (viator) is  living. The buyer (funder), usually an investment company, pays the  patient a lump sum of 50-80% of the policy�s face value, pays the pre�  miums until the patient dies, and receives the death benefit. Viatical settle�  ments (from Latin viaticum, �provisions for a journey�) appeared in the  1980s, when people with AIDS had high medical bills and policies nomi�  nally sufficient to cover them but whose funds would not be available  until they died.</p><p>vibraphone or vibraharp Percussion instrument with tuned metal  bars, arranged keyboard-style like the xylophone. Felt or wool beaters are  used to strike the bars, giving a soft, mellow tone quality. Each bar has a  resonating tube suspended vertically below it to sustain the tone; small  electrically powered spinning disks at the top of the resonators produce a  vibrato effect by rapidly closing and opening the resonators. Invented c.  1920, it soon became a popular jazz instrument.</p><p>vibration Periodic back-and-forth motion (see periodic motion) of the  particles of an elastic body or medium. It is usually a result of the dis�  placement of a body from an equilibrium condition, followed by the body�s  response to the forces that tend to restore equilibrium. Free vibrations  occur when a system is disturbed but immediately allowed to move with�  out restraint, as when a weight suspended by a spring is pulled down and  then released. Forced vibrations occur when a system is continuously  driven by an external agency, as when a child�s swing is pushed on each  downswing. Because all systems are subject to friction, they are also sub�  ject to damping. In the example of free vibration, damping would cause  the amplitudes of the spring�s vibrations to diminish until eventually the  system came to rest.

His first plays were produced in 1502, and for the next 34  years he acted as court dramatist and poet laureate, staging his plays to  celebrate great events and religious occasions. Regarded as the founder  of Portuguese drama, he wrote in both Portuguese and Spanish. His 44  extant plays reflect the change and upheaval of his era; they may be  divided into religious plays, court plays, pastoral plays, popular farces,  and romantic comedy. His works include Exhortation to War (1513), The  Forge of Love (1524), and The Pilgrimage of the Aggrieved (1533).</p><p>Vichy \'ve-she\ France officially French State French Etat  Francais (July 1940-September 1944) French regime in World War II  after the German defeat of France. The Franco-German armistice (June  1940) divided France into two zones: one under German military occu�  pation and one under nominal French control (the southeastern two-fifths  of the country). The National Assembly, summoned at Vichy to ratify the  armistice, was persuaded by Pierre Laval to grant Philippe Petain authority  to assume full powers in the French State. The antirepublican Vichy gov�  ernment collaborated with the Germans and became increasingly a tool  of German policy, especially after the Germans occupied the whole of  France in 1942. By early 1944 the Resistance movement against the  Gestapo and Vichy militias created a period of civil war in France, and  after the liberation of Paris the Vichy regime was abolished.</p><p>Vicksburg Campaign (1862-63) Engagements fought at Vicksburg,  Miss., in the American Civil War. Confederate forces held the fortified city  against Union naval bombardment from the Mississippi River (1862) and  attempts to attack by land. In April 1863 Ulysses S. Grant used the Union  ships to ferry troops across the river at night. He quickly took nearby Port  Gibson and Grand Gulf to prevent Confederate forces under Joseph  Johnston from aiding those in the city. Unable to take Vicksburg directly,  Grant besieged the city for six weeks. On July 4 Gen. John Pemberton  (1814-1881) surrendered his force of 30,000, leaving the Mississippi  River completely under Union control and splitting the Confederacy in  half.</p><p>Vico \'ve-k6\, Giambattista (b. June 23, 1668, Naples�d. Jan. 23,  1744, Naples) Italian philosopher of cultural history and law. In his major  work, New Science (1725), he attempted to combine history and the more  systematic social sciences into a single science of humanity. He described  human societies as passing through stages of growth and decay. The first  is a �bestial� condition, from which emerges �the age of the gods,� in  which man is ruled by fear of the supernatural. �The age of heroes� is the  consequence of alliances formed by family leaders to protect against inter�  nal dissent and external attack; in this stage, society is rigidly divided into  patricians and plebeians. �The age of men� follows, as the result of class  conflict in which the plebeians achieve equal rights, but this stage encoun�  ters the problems of corruption, dissolution, and a possible reversion to  primitive barbarism. His work is recognized as a forerunner of cultural  ANTHROPOLOGY.</p><p>Victor III orig. Dauferi (b. 1027, Benevento, principality of  Benevento�d. Sept. 16, 1087, Montecassino, principality of Capua;  beatified July 23, 1887; feast day September 16) Pope (1086-87). As  abbot of Monte Cassino from 1058, he promoted manuscript illumination,  established a school of mosaic, and reconstructed the abbey. He served  as papal vicar in southern Italy, negotiating peace between the Normans  and the papacy. He was proclaimed pope against his will and was soon  driven from Rome by supporters of Emperor Henry IV and the antipope  Clement III. In 1087, after briefly retiring to his abbey, Victor resumed  his papal authority and promoted the reforms of his predecessor, Pope  Gregory VII. After sending an army to defeat the Saracens at Tunis (1087),  he called a synod at Benevento and excommunicated Clement. He fell ill  and returned to Monte Cassino, where he died.</p><p>Victor Amadeus \,am-3-'da-3s\ II Italian Vittorio Amedeo (b.</p><p>May 14, 1666, Turin, Savoy�d.

The son of Charles  Emmanuel II, he inherited his father�s title as duke of Savoy in 1675 and  grew up under a regency headed by his mother, who pursued a pro-French  policy. In the War of the Spanish Succession he sided with France, but in  1703 he shifted to the Habsburg side. With the French defeat at Turin  (1706) he secured his position in Italy. The Treaty of Utrecht (1713) gave  him the title of king of Sicily, which he was obliged to exchange for Sar�  dinia in 1720. As the first king of Sardinia, which also included Piedmont  and Savoy, he established the foundation for the future Italian national  state.</p><p>Victor Emmanuel I Italian Vittorio Emanuele (b. July 24, 1759,  Turin, Kingdom of Sardinia�d. Jan. 10, 1824, Moncalieri, near Turin)  King of Sardinia (1802-21). Son of Victor Amadeus III and great-  grandson of Victor Amadeus II, he led Sardinian forces against the French  (1792-97). He became duke of Savoy and king of Sardinia in 1802 when  his brother Charles Emmanuel IV abdicated. His kingdom, except for the  island of Sardinia, was occupied by France (1802-14), then restored with  the addition of Genoa by the Congress of Vienna (1815). He abdicated in  1821 in favour of his brother Charles Felix (1765-1831).</p><p>Victor Emmanuel II Italian Vittorio Emanuele (b. March 14,  1820, Turin, Piedmont, Kingdom of  Sardinia�d.

The son of Charles Albert, he  took part in the war against Austria  (1848) and became king when his  father abdicated in 1849. Assisted by  his minister Camillo Cavour, he  strengthened the kingdom and sup�  ported the Risorgimento movement  for unity. In the war with Austria  (1859-61), he commanded troops to  victories in the Battles of Magenta  and Solferino. He secretly encour�  aged Giuseppe de Garibaldi in the con�  quest of Sicily and Naples and led  the invasion of the Papal States. He  assumed the title of king of Italy  (1861) and later acquired Venetia  (1866) and Rome (1870).</p><p>Victor Emmanuel \\ Italian Vittorio Emanuele (b. Nov. 11, 1869,  Naples, Italy�d. Dec. 28, 1947, Alexandria, Egypt) King of Italy (1900-  46). Son of Umberto I, he came suddenly to the throne on his father�s  assassination (1900). He accepted a Liberal cabinet and readily agreed to  Italy�s war against Turkey (1911-12) and entry into World War I. After  the war, he failed to prevent the rise of Benito Mussolini and the fascist  seizure of power, which turned him into a figurehead sovereign. In 1943,  after disastrous Italian military losses and the Allied invasion of Sicily,  he had Mussolini arrested and replaced by Pietro Badoglio as premier. In  1944 he relinquished power to his son Umberto and, in an unsuccessful  attempt to preserve the monarchy, abdicated in Umberto�s favour in 1946  (see Umberto II). When the Italian republic was declared in 1946, father  and son went into exile.</p><p>Victoria orig. Alexandrina Victoria (b. May 24, 1819, Kensing�  ton Palace, London, Eng.�d. Jan. 22, 1901, Osborne, near Cowes, Isle  of Wight) Queen of the United Kingdom of Great Britain and Ireland  (1837-1901) and Empress of India (from 1876). The only child of  Edward, duke of Kent, she succeeded her uncle, William IV, in 1837. She  was first guided as queen by the Whig prime minister Lord Melbourne and  then by her husband, Prince Albert, whom she married in 1840. Devoted  to him, she accepted his decisions on all issues in the period sometimes  called the �Albertine monarchy.� They had nine children, through whose  marriages descended many of the royal families of Europe. From 1861  Victoria deeply mourned Albert�s death and thereafter made royal deci�  sions as she believed he would have advised. She was frequently at odds  with Prime Minister William E. Gladstone and welcomed his replacement  by Benjamin Disraeli in 1874. Her reign, called the Victorian age, was  marked by a period of British expansion and a restoration of dignity and</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2002 I Victoria &#x25BA; video card</p><p>popularity to the monarchy, as shown by her Jubilees of 1887 and 1897.

It covers  an area of 87,810 sq mi (227,420 sq km); its capital is Melbourne. The  state�s western and northwestern parts are sandy desert and lowland, while  the central and eastern parts are highlands forming the southern end of  the Australian Alps. The southwestern coastal region is known as  Gippsland. The Murray River forms almost the entire boundary between the  state and New South Wales. Australian Aboriginal peoples had lived in the  region for at least 40,000 years before contact with Europeans. Some 60  years after Capt. James Cook first sighted its coastline (1770), the area  was settled by immigrants from Tasmania, who brought in their wake dis�  eases that decimated much of the Aboriginal population. Victoria became  a separate colony in 1851. In 1901 it became a state of the Common�  wealth of Australia.

The southern half lies in  Tanzania, the northern half in Uganda; it borders Kenya in the northeast.  With an area of 26,828 sq mi (69,484 sq km), it is the second largest  freshwater lake in the world (after Lake Superior in North America). It is  about 210 mi (337 km) long, 150 mi (240 km) wide, and up to 270 ft (82  m) deep. Though the Kagera River is its largest tributary, the most impor�  tant source of water for the lake is rainfall. Its only outlet is the Victoria  Nile. John Hanning Speke, searching for the source of the Nile in 1858,  was the first European to sight it. He named it for Queen Victoria; the  Arabs had called it Ukerewe. Henry Morton Stanley circumnavigated it  in 1875. It became a reservoir when the water level was raised after  completion of Owen Falls Dam in 1954.</p><p>Victoria, Tomas Luis de (b. c. 1548, near Avila, Spain�d.

He went to Rome c. 1565 as an organ�  ist and singer, and he may have studied with Giovanni Pierluigi da Pal�  estrina, eventually becoming kapellmeister for a Jesuit congregation  (1573-77). Ordained a priest (1575), he was associated with St. Philip  Neri�s group (1578-85). During this time he published his books of  motets, masses. Magnificats, and hymns. In 1587 he returned to Spain as  chaplain to the dowager empress Maria, in whose convent he served as  organist and choirmaster until his death. He wrote 21 masses (including  a Pope Marcellus Mass), several Magnificats, and 44 motets (including  O magnum mysterium). His music is mystical, impressive, and moving,  and he was renowned as the greatest Spanish composer of the Renais�  sance.</p><p>Victoria, University of Public university in Victoria, British Colum�  bia, Canada, founded in 1903.

They mark their territory with  communal dung heaps. Vicunas are untamable but have been hunted for  centuries; they are now protected as an endangered species.</p><p>Vidal Vve-.dal, ve-'dal. Gore orig. Eugene Luther Vidal (b. Oct.  3, 1925, West Point, N.Y., U.S.) U.S. novelist, playwright, and essayist.  Vidal began publishing his writings soon after his wartime army service.  Though he wrote stage plays and television and film screenplays, he is  best known for his irreverent and intellectually adroit novels. The City  and the Pillar (1948) became notorious for its homoerotic subject mat�  ter. Myra Breckenridge (1968) was acclaimed for its wild satire. His other  novels, many of them historical and most of them best-sellers, include  Julian (1964), Washington, D.C. (1967), Burr (1974), 1876 (1976), and  Lincoln (1984). He also published several essay collections and the mem�  oir Palimpsest (1996).

Located on the Danube River, it was founded  by the Celts; it became a Roman military station in the 1st century bc. Ruled  by many�including the Franks in the 6th century ad and the Magyars in  the 10th century�Vienna was an important trade centre during the Cru�  sades. It was the seat of the Holy Roman Empire (1558-1806), of the Austrian  (and Habsburg) Empire (1806-67), and of the Austro-Hungarian Empire  until 1918. In 1814�15 it was the seat of the Congress of Vienna. The  administrative centre of German Austria (1938-45), it was frequently  bombed during World War II by the Allies, and the city was taken by Soviet  troops in 1945. It was under joint Soviet-Western Allied occupation from  1945 to 1955. The Strategic Arms Limitation Talks (SALT) between the U.S.  and Soviet Union took place in Vienna in the 1970s. The commercial and  industrial centre of Austria, it also is a cultural centre renowned for its  architecture and music. It was the birthplace of the composers Franz Schu�  bert, Johann Strauss (the Younger), and Arnold Schoenberg, and the home  of Wolfgang Amadeus Mozart, Ludwig van Beethoven, Johannes Brahms, and  Gustav Mahler. It also was the home of Sigmund Freud, Gustav Klimt, Oskar  Kokoschka, and Josef Hoffmann.

The powers of the Quadruple Alliance had con�</p><p>cluded the Treaty of Chaumont just before Napoleon�s first abdication and  agreed to meet later in Vienna. There they were joined by Bourbon France  as a major participant and by Sweden and Portugal; many minor states  also sent representatives. The principal negotiators were Klemens, prince  von Metternich, representing Francis II (Austria); Alexander I (Russia); Fred�  erick William III and Karl August, prince von Hardenberg (Prussia); Vis�  count Castlereagh (Britain); and Charles-Maurice de Talleyrand (France).  The Congress reduced France to its 1789 borders. A new kingdom of  Poland, under Russian sovereignty, was established. To check possible  future aggression by France, its neighbours were strengthened: the king�  dom of The Netherlands acquired Belgium, Prussia gained territory along  the Rhine River, and the Italian kingdom acquired Genoa. The German  states were joined loosely in a new German Confederation, subject to  Austria�s influence. For its part in the defeat of Napoleon, Britain acquired  valuable colonies, including Malta, the Cape of Good Hope, and Ceylon.  The Vienna settlement was the most comprehensive treaty that Europe  had ever seen, and the configuration of Europe established at the congress  lasted for more than 40 years.</p><p>Vienna, Siege of (July 17-Sept. 12, 1683) Attempted capture of  Vienna by Ottoman Turkey. On appeal from the Hungarian Calvinists to  attack the Habsburg capital, the Turkish grand vizier, Kara Mustafa  (1634-83), and his army of 150,000 laid siege to Vienna in July 1683,  after capturing its outer fortifications. Pope Innocent XI convinced John  III Sobieski of Poland to lead a combined army of 80,000 to relieve the  siege. On Sept. 12, 1683, Sobieski, aided by Charles of Lorraine, led the  attack from the surrounding hills and after 15 hours drove the Turks from  their trenches around the city. Thousands were slaughtered or taken pris�  oner. The event marked the beginning of the decline of Turkish domina�  tion in eastern Europe.</p><p>Vienna, University of State-financed university at Vienna, Austria.

It was reorganized in 1384,  becoming particularly noted for its faculties of medicine, law, and theol�  ogy. It was a centre of revolution during the uprising of 1848, when Met-  temich was forced from power. The modern university includes faculties  of theology, social sciences and economics, medicine, sciences, math�  ematics, and natural sciences.</p><p>Vienna Circle German Wiener Kreis Vve-nor-'krisX Group of phi�  losophers, scientists, and mathematicians formed in the 1920s that met  regularly in Vienna to investigate scientific language and scientific method.

The movement associated with the Circle has been  called logical positivism. Its members� work was distinguished by their  attention to the form of scientific theories, their formulation of a verifi�  ability principle of meaning, and their espousal of a doctrine of unified sci�  ence. The group dissolved after the Nazis invaded Austria in 1938.</p><p>Vientiane \,vyen-'tyan\ Laotian Viangchan \,vyeq-'chan\ City (pop.,  1999 est.: 534,000), capital of Laos.

In 1778 it  came under Siamese (Thai) control; in 1828 it was destroyed when the  Laotian king revolted against the Siamese. The French made it the capi�  tal of their colony on their takeover of the region in the 1890s; it remained  the administrative centre after Laos gained independence in 1953.

The Viet Cong�s guerrilla war against the South  Vietnamese government and its powerful U.S. allies was successful; the  U.S. withdrew its troops from Vietnam between 1969 and 1973, and the  PRG assumed power in South Vietnam in 1975, following a full-scale  invasion. It became part of a National United Front the following year.</p><p>Viet Minh Vvyet-'minX in full Viet Nam Doc Lap Dong Minh Hoi  English "League for the Independence of Vietnam" Organi�  zation that led the struggle for Vietnamese independence from French  rule. Formed in 1941 by Ho Chi Minh, it was a national organization open  to people of all political leanings, though it was led by communists. In  1943 the Viet Minh began guerrilla operations against the occupying Japa�  nese; when the Japanese surrendered to the Allies, the Viet Minh seized  Hanoi and proclaimed Vietnam�s independence. In the First Indochina  War that followed, the Viet Minh (and the Vietnamese Workers� Party  [Lao Dong] that succeeded them) defeated the French. Elements of the  Viet Minh also joined the Viet Cong to fight the U.S. in the Vietnam War.  See also Vo Nguyen Giap.</p><p>Vietnam officially Socialist Republic of Vietnam Country,  Southeast Asia. Area: 128,379 sq mi (332,501 sq km). Population (2005  est.): 82,628,000. Capital: Hanoi. The great majority of the population is</p><p>into northern and southern dynasties in the early 17th century, and in 1802  these two parts were unified under a single dynasty. Following several  years of attempted French colonial expansion in the region, the French  captured Saigon (now Ho Chi Minh City) in 1859 and later the rest of the  area, controlling it until World War II (see French Indochina). The Japa�  nese occupied Vietnam in 1940-45 and allowed the Vietnamese to declare  independence at the end of the war, a move the French opposed. The First  Indochina War ensued and lasted until French forces with U.S. financial  backing were defeated by the Vietnamese at Dien Bien Phu in 1954; evacu�  ation of French troops followed. After an international conference at  Geneva (April-July 1954), Vietnam was partitioned along latitude 17� N,  with the northern part under the communist leadership of Ho Chi Minh  and the southern part under the U.S.-supported former emperor Bao Dai;  the partition was to be temporary, but the reunification elections sched�  uled for 1956 were never held. An independent South Vietnam (Republic  of Vietnam) was declared, while the communists established North Viet�  nam (Democratic Republic of Vietnam). The activities of North Vietnam�  ese guerrillas and procommunist rebels in South Vietnam led to U.S.  intervention and the Vietnam War. A cease-fire agreement was signed in  1973 and U.S. troops withdrawn, but the civil war soon resumed; in 1975  North Vietnam invaded South Vietnam, and the South Vietnamese gov�  ernment collapsed. In 1976 the two Vietnams were united as the Social�  ist Republic of Vietnam. From the mid-1980s the government enacted a  series of economic reforms and began to open up to Asian and Western  nations. In 1995 the U.S. officially normalized relations with Vietnam.</p><p>Vietnam Veterans Memorial Monument in Washington, D.C.,  designed by Maya Lin.

Engraved on the mirrorlike surface are the names  of the more than 58,000 U.S. dead and missing-in-action who served in  the Vietnam War, listed by date of casualty. When Lin�s abstract design  was announced, several veterans groups and others protested; eventually  a traditional statue depicting three servicemen with a flag was commis�  sioned, to stand at the entrance to the site. Since its dedication in 1982,  the controversial wall has become one of the city�s most visited and most  affecting tourist attractions.</p><p>Vietnam War (1955-75) Protracted effort by South Vietnam and the  U.S. to prevent North and South Vietnam from being united under com�  munist leadership. After the First Indochina War, Vietnam was partitioned  to separate the warring parties until free elections could be held in 1956.  Ho Chi Minh�s popular Viet Minh party from the north was expected to win  the elections, which the leader in the south, Ngo Dinh Diem, refused to  hold. In the war that ensued, fighters trained in the north (the Viet Cong)  fought a guerrilla war against U.S.-supported South Vietnamese forces;  North Vietnamese forces later joined the fighting. At the height of U.S.  involvement, there were more than half a million U.S. military personnel  in Vietnam. The Tet Offensive of 1968, in which the Viet Cong and North  Vietnamese attacked 36 major South Vietnamese cities and towns, marked  a turning point in the war. Many in the U.S. had come to oppose the war  on moral and practical grounds, and Pres. Lyndon B. Johnson decided to  shift to a policy of �de-escalation.� Peace talks were begun in Paris.  Between 1969 and 1973 U.S. troops were withdrawn from Vietnam, but  the war was expanded to Cambodia and Laos in 1970. Peace talks, which  had reached a stalemate in 1971, started again in 1973, producing a cease�  fire agreement. Fighting continued, and there were numerous truce vio�  lations. In 1975 the North Vietnamese launched a full-scale invasion of  the south. The south surrendered later that year, and in 1976 the country  was reunited as the Socialist Republic of Vietnam. More than 2,000,000  people (including 58,000 Americans) died over the course of the war,  about half of them civilians.</p><p>Vietnamese language Mon-Khmer language, the native language of  60-65 million people in Vietnam and a second language for many members  of Vietnam�s more than 50 minority ethnic groups, with some 2 million  speakers outside the country.

By the 13th century Chinese characters were  adapted to write native Vietnamese words. In the 17th century Roman  Catholic missionaries introduced a system of writing Vietnamese in the  Latin alphabet with diacritics distinguishing vowel qualities and tones, a sys�  tem that was widely adopted only in the 20th century.</p><p>Vigano \ve-'ga-no\, Salvatore (b.

His  Cinq-Mars (1826) was the first important historical novel in French.  Growing disillusioned, he wrote Stello (1832), on the advisability of sepa�  rating the poetic life from the political. Chatterton (1835), his best play  and one of the finest Romantic dramas, glorifies the anguish of the mis�  understood artist. His pessimism was manifest also in The Military Neces�  sity (1835), whose first and third stories are his prose masterpieces. In  middle age he withdrew from Paris society.

In 865 Vikings conquered East Anglia, Northumbria, and  much of Mercia. Wessex under Alfred the Great made a truce in 878 that  led to Danish control of much of England. Alfred defeated fresh Viking  armies (892-899), and his son continued his reconquest, recovering lands  in Mercia and East Anglia by 924; Viking Northumbria fell in 954.  Renewed raids in 980 brought England into the empire of Canute, and it  remained as such until 1042, when native rule was restored.The Vikings  permanently affected English social structure, dialect, and names. In the  western seas, Vikings had settled in Iceland by 900, whence they traveled  to Greenland and North America. They invaded Ireland in 795, establish�  ing kingdoms at Dublin, Limerick, and Waterford. The Battle of Clontarf  (1014) ended the threat of Scandinavian rule. France suffered periodic  Viking raids but no domination. In Russia Vikings briefly dominated  Novgorod, Kiev, and other centres, but they were quickly absorbed by the  Slav population. As traders they made commercial treaties with the Byz�  antines (912, 945), and they served as mercenaries in Constantinople.

Self-  taught as a composer, he met Darius Milhaud in 1917, and Artur Rubinstein  later promoted his music and helped support him. A �week of modem  art� in Sao Paulo (1922) brought his music to national attention, and he  was given a grant to go to Paris (1923-30), where his music was received  enthusiastically. On his return he became a leader in musical education�  founding the Ministry of Education conservatory (1942) and the Brazil�  ian Academy of Music (1945)�and Brazil�s semiofficial ambassador to  the world. His many works include his 9 Bachianas brasileiras for vari�  ous ensembles and his 14 Choros, based on a popular form of street music.</p><p>Villafranca \,ve-la-'fraq-ka\ A Peace of (1859) Preliminary peace  treaty between France�s Napoleon III and Austria�s emperor Francis Joseph  that ended the Franco-Piedmontese war against Austria. Napoleon III  made peace after the costly Battle of Solferino without consulting the  Piedmontese king, Victor Emmanuel II. By the peace terms, Lombardy was  ceded to France and then to Piedmont, and the dukes of Parma, Modena,  and Tuscany were restored to their thrones after being deposed by nation�  alists. Though decried by Italian nationalists, the peace marked the begin�  ning of Italy�s unification under Piedmontese leadership.</p><p>Vijnanavada See Yogacara</p><p>Viking Either of two unmanned U.S. spacecraft launched by NASA in  1975.

In 1853 he  immigrated to the U.S., where he first found work with German-language  newspapers. During the Civil War he was a correspondent for two New  York City newspapers. In 1881 he purchased the Nation magazine and  the New York Evening Post. In the 1870s he organized several railroads  in Oregon, and from 1881 to 1884 he was president of the Northern  Pacific, a transcontinental railroad completed under his management  despite large cost overruns; he later served as chairman of the board  (1888-93).

Francois de Montcorbier  or Francois des Loges (b. 1431, Paris, France�d. after 1463) French  lyric poet. Villon was a rigorously trained scholar who led a life of crimi�  nal excess; he killed a priest in 1455, then joined a criminal organization  and became involved in robbery, theft, and brawling. Incarcerated several  times, in 1462 he received a death sentence that was commuted to ban�  ishment. He was never heard from again. His works, published posthu�  mously, include the poem Le Petit testament (1489), which takes the form  of ironic bequests to friends and acquaintances; Le Testament (1489),  which reviews his life with great emotional and poetic depth; and vari�  ous ballades, chansons, and rondeaux. His themes range from drunken�  ness and prostitution to a humble ballade-prayer to the Virgin written at  his mother�s request. Villon�s verse makes a direct, unsentimental appeal  to the emotions but also displays remarkable control of rhyme and dis�  ciplined composition.</p><p>Vilnius Vvil-ne-9s\ City (pop., 2001: 542,287), capital of Lithuania.  Founded in the 10th century, it became the capital of Lithuania in 1323.  It was destroyed in 1377 by the Teutonic Knights but was rebuilt. Vilnius  passed to Russia in 1795, and for several centuries was a noted European  centre for Jewish learning. It was occupied by the Germans in World Wars  I and II and suffered heavy damage. From 1920 to 1939 it was part of  Poland; taken by Soviet troops in 1939, it was restored to Lithuania, which  the Soviets annexed in 1940. One result of the World War II German  occupation was the decimation of the city�s Jewish population, which  dropped from 80,000 in 1941 to 6,000 in 1945. In 1991 it became the  capital of the newly independent Lithuania. An important industrial cen�  tre, it also has many historic buildings representing Gothic, Renaissance,  and Baroque styles of architecture.</p><p>Vilnius dispute Conflict between Poland and Lithuania over posses�  sion of the city of Vilnius.

Probably first made from wine (French vinaigre means �sour wine�), vin�  egar may also be made from malted barley, rice, cider, or other substances.  The source substance, which must contain sugar, is fermented by yeast to  produce alcohol. The alcohol is then aerated, which causes it to convert,  through the action of Acetobacter bacteria, to acetic acid, water, and vari�  ous other compounds.

The viols are distinguished  from the violin family particularly by a fretted fingerboard, sloping shoul�  ders, flat back, six strings, and milder tone. They exist in four sizes: treble,  tenor, bass, and double bass (violone). They are played vertically, the body  of the instrument being held between the legs or rested on the knee. The</p><p>viol family appeared in the late 15th century and soon became widely  popular and acquired a large repertory. Throughout the Baroque era, the  bass viol joined the harpsichord in the basso continuo. The contempora�  neous violin family, having a more penetrating tone, gradually displaced  the viols in the 18th century.</p><p>viola \vI-'o-b, ve-'6-b\ Stringed instrument, the tenor member of the vio�  lin family. In appearance it is almost identical to the violin but slightly  larger; its strings are tuned a fifth lower. It is a member of many chamber  music ensembles, and the modern orchestra uses 6 to 10 violas. Its tone is  darker, warmer, and less powerful than the violin�s, and it is rarely  employed as a solo instrument. The viola d�amore is an 18th-century  instrument with six or seven melody strings, under which are strung sev�  eral sympathetic strings that resonate in concord with the sounded pitches.</p><p>violet Any of the approximately 500 species of herbaceous plants or low  shrubs that make up the genus Viola, which includes the small, solid-  coloured violets and the larger-flowered, often multicoloured violas and  pansies. Many Viola species have two types of flowers: the showy spring  flower is infertile; the less conspicuous summer flower is self-fertilizing.  The best-known species of Viola have heart-shaped leaves. The popular  florist�s violets, consisting of several hybrids (many of them V. odorata),  are usually called sweet violets. The family Violaceae, to which Viola  belongs, has members worldwide; they are typically small trees and  shrubs that grow as low vegetation beneath the taller trees of forests. The  so-called African violet belongs to the gesneriad family. See also dogtooth  violet.</p><p>violin Bowed stringed instrument. The violin is the highest-pitched mem�  ber of a family of instruments that includes the viola, cello, and double  bass. It has a fretless fingerboard, four strings, and a distinctively shaped  wooden body whose �waist� permits freedom of bowing. The violin is  held on the shoulder and bowed with the right hand. It has a wide range  of more than four octaves. It evolved in Italy in the 16th century from the  medieval fiddle and other instruments. Its average proportions were  settled by the 17th century, but innovations in the 18th-19th centuries  increased its tonal power. With its brilliance, agility, and singing tone, the  violin has been immensely important in Western art music, and it has the  largest and most distinguished repertoire of any stringed instrument. From  the mid-17th century it has been the foundation of the symphony orches�  tra, which today usually includes 20-26 violins, and it is also widely used  in chamber music and as a solo instrument. It is played as a folk instru�  ment in many countries, folk violins being often called fiddles.</p><p>Viollet-le-Duc V.ve-o-'la-b-'dtikV Eugene-Emmanuel (b. Jan. 27,  1814, Paris, France�d.

After studying architecture  and training as an archaeologist, he  was placed in charge of restoring the  abbey church at Vezelay (1840). He  assisted in restoring the Sainte-  Chapelle (1840) and Notre-Dame de  Paris (1845) and supervised the res�  toration of many other medieval  buildings, including Amiens Cathe�  dral (1849) and the fortifications of  Carcassonne (1852). In his later res�  torations he often added new ele�  ments of his own design, intrusions  for which he was criticized in the  20th century. He is most distin�  guished for his writings, which  include the Dictionnaire raisonne de  l�architecture frangaise du Xle au  XVIe siecle (1854-68) and Entre-  tiens sur l�architecture (1858-72).

A god of rain, he was  believed to have created the Sun on the waters and foam of Lake Titicaca.  After forming the rest of the heavens and the earth, he wandered through  the world teaching humankind the arts of civilization. At Manta (Ecua�  dor) he walked westward across the Pacific Ocean, promising to return  one day. His cult was extremely ancient, and he is probably the weeping  god sculpted in the megalithic ruins at Tiwanaku.</p><p>viral VvI-rolX diseases Diseases caused by viRUses. Long-term immunity  usually follows viral childhood diseases (see chickenpox). The common  cold recurs into adulthood because many different viruses cause its symp�  toms, and immunity against one does not protect against others. Some  viruses mutate fast enough to reinfect people after recovery (see influ�  enza) or to keep the immune system from fighting them off (see AIDS). Cer�  tain cancers are caused by viruses.

He held the first chairs of  pathological anatomy at the Universities of Wurzburg (1849-56) and Ber�  lin (1856-1902). In 1861 he was elected to the Prussian Diet and founded  the Progressive Party. He coined the terms thrombosis and embolism while  disproving the theory that phlebitis causes most diseases. His work sup�  ported emerging ideas on cell division and metabolism, pointing out that  cell division accounted for the multiplication of cells to form tissues. His  rejection of the theory that bacteria cause disease and of Ignaz Semmel-  weis�s advocacy of antisepsis delayed the use of antiseptics. Virchow also  founded two anthropological societies and accompanied Heinrich Schlie-  mann to Troy (1879) and Egypt (1888).</p><p>vireo Vvir-e-,o\ Any of 42 species (family Vireonidae) of New World  songbirds with a stout, slightly notched, hook-tipped bill that has fine  bristles at the base.

They glean insects from foli�  age in woodlands and thickets, repeating loud short phrases over and over.  The nest is a cuplike structure suspended from a small fork in a branch.  The red-eyed vireo (Vireo olivaceus), which breeds from southern Canada  to Argentina, is 6 in.

Sept. 21, 19 bc, Brundisium) Greatest of  Roman poets. The well-educated son of a prosperous provincial farmer,  Virgil led a quiet life, though he eventually became a member of the circle  around Octavian (later Caesar Augustus) and was patronized by Maece�  nas. His first major work, the 10 pastoral Eclogues (42-37), may be read  as a prophecy of tranquility, and one has even been read as a prophecy  of Christianity. The Georgies (37-30) point toward a Golden Age in the  form of practical goals: the repopulation of rural lands and the rehabili�  tation of agriculture. His great epic, the Aeneid (begun c. 29, but unfin�  ished at his death), is one of the masterpieces of world literature. A  celebration of the founding of Rome by the legendary Aeneas at the  request of Augustus, whose consolidation of power in 31-30 unified the  Roman world, it also explores the themes of war and the pathos of unre�  quited love. In later centuries his works were regarded in the Roman  Empire as virtually sacred. He was taken up reverently by Christians as  well, including Dante, who, in his poem The Divine Comedy, made Vir�  gil his guide through hell and purgatory.</p><p>Virgin Birth Fundamental doctrine of orthodox Christianity that Jesus  had no natural father but was conceived by Mary through the power of  the Holy Spirit. Based on the infancy narratives in the Gospels of Matthew  and Luke, the doctrine was universally accepted in the Christian church  by the 2nd century. It remains a basic article of belief in Roman Catholi�  cism, Eastern Orthodoxy, most Protestant churches, and Islam. A corol�  lary of its dogma is the doctrine of Mary�s perpetual virginity, accepted  by the Orthodox and Roman Catholic churches and by some Lutheran  and Anglican theologians. See also Immaculate Conception.</p><p>Virgin Islands, British British overseas territory (pop., 2005 est.:  27,200), West Indies. Part of the Virgin Islands chain, it consists of the  islands of Tortola, Anegada, Virgin Gorda, and Jost Van Dyke and 32  smaller, mostly uninhabited islands. The chief town and port is Road  Town on Tortola. The majority of British Virgin Islanders are of African  or African-European descent. English is the chief language. Religion:  Christianity (predominantly Protestant). The islands are generally hilly,  and many have lagoons with coral reefs and barrier beaches. Tourism is  the mainstay of the economy. The Virgin Islands probably were originally  settled by Arawak Indians but were inhabited by Caribs by the time Chris�  topher Columbus visited in 1493. The islands were a haunt for pirates, and  Tortola was held by Dutch buccaneers until it was taken by English plant�  ers in 1666; it was annexed by the British-administered Leeward Islands  in 1672. The British sugar plantations declined after slavery was abol�  ished in the 19th century. The islands were part of the Colony of the Lee�  ward Islands from 1872 until 1956, when the British Virgin Islands  became a separate colony. Its status was changed to an overseas territory  in 2002.</p><p>Virgin Islands National Park Conservation area, St. John, U.S.  Virgin Islands.

The great majority of the population is of African descent; most  of the remainder are Hispanic (mainly Puerto Rican) or recent immigrants  from the U.S. The people are U.S. citizens and elect a nonvoting repre�  sentative to the U.S. House of Representatives, but they do not vote in  U.S. national elections. Languages: English (official), French, Spanish.  Religion: Christianity (mainly Protestant; also Roman Catholic, other  Christians). The islands are hilly and surrounded by coral reefs. Tourism  dominates the economy. The islands probably were originally settled by  Arawak Indians but were inhabited by the Caribs by the time Christopher  Columbus landed on St. Croix in 1493. St. Croix was occupied by the  Dutch, English, French, and Spanish and at one time was owned by the  Knights of Malta. Denmark occupied St. Thomas, St. John, and St. Croix  and established them as a Danish colony in 1754. The U.S. purchased the  Danish West Indies in 1917 for $25 million and changed the name to the  Virgin Islands. They were adminis�  tered by the U.S. Department of the  Interior from 1931. In 1954 the  Organic Act of the Virgin Islands  created the current governmental  structure, and in 1970 the first popu�  larly elected governor took office.</p><p>The area suffered extensive damage  by a major hurricane in 1995.</p><p>virginal or virginals Small rect�  angular harpsichord with a single set  of strings and a single manual.

North Carolina and Tennessee to the south,  Kentucky to the west, West Virginia to the northwest, and the Atlantic  Ocean to the east. Located on the central Atlantic seaboard, it covers an  area of 40,600 sq mi (105,154 sq km); its capital is Richmond. The coastal  plain, also known as the Tidewater, lies in the east; the Piedmont prov�  ince, a region of rolling hills, is in the middle of the state; and the Blue  Ridge and Appalachian mountains lie to the west. The Potomac, Shenan�  doah, James, and Roanoke rivers flow through the state. Virginia was  inhabited by American Indians when England�s first American colony was  founded there in 1607 at Jamestown. Virginia�s citizens were among the  leaders of the American Revolution, and the state later contributed four of  the country�s first five presidents. In 1788 it became the 10th state to ratify  the U.S. Constitution. Slavery was an important part of Virginia�s  economy; Nat Turner�s slave insurrection occurred there in 1831. In 1861,  soon after the start of the American Civil War, Virginia seceded from the  Union. Richmond became the capital of the Confederacy (see Confeder�  ate States of America), and Virginia was the chief battleground through�  out the war. The western part of the state refused to secede; it split off to  become West Virginia in 1863. Virginia was readmitted to the Union in  1870. Strife over state debt took over political life for the next decades,  but after World War I the state�s prosperity increased. World War II  brought thousands to Virginia�s military camps and caused the Norfolk  area to experience rapid growth. The federal government is the state�s  largest employer, while manufacturing is the second largest. Hampton  Roads is one of the nation�s leading ports. Tourism is important; Virgin�  ia�s many historical sites include Colonial Williamsburg, George Wash�  ington�s Mount Vernon, Thomas Jefferson�s Monticello, Civil War  battlefields, and Gen. Robert E. Lee�s house, located within the grounds of  what is now Arlington National Cemetery. The College of William and  Mary (founded 1693) is the country�s second oldest college; the Univer�  sity of Virginia was largely the creation of Thomas Jefferson.</p><p>Virginia, University of U.S. public university founded in Char�  lottesville by Thomas Jefferson. It was chartered in 1819 and opened in  1825. Jefferson designed its beautiful campus and buildings, planned the  curriculum, and selected the faculty. By the time of the Civil War, the  university was second only to Harvard in size of faculty and student body.  It first admitted women in 1970. In addition to its college of arts and sci�  ences, it has schools of architecture, education, engineering and applied  sciences, and nursing, as well as a business school, a graduate school, and  schools of law and medicine.</p><p>Virginia and Kentucky Resolutions (1788-89) Measures passed  by the legislatures of Virginia and Kentucky as a protest against the Alien  and Sedition Acts. Drafted by James Madison and Thomas Jefferson (though  their role went unknown for 25 years), the resolutions protested limita�  tions on civil liberties and declared the right of states to decide on the  constitutionality of federal legislation. Though their authors applied the  resolutions to the specific issues of the day. Southern states later used the  measures to support the theories of nullification and secession.</p><p>Virginia Beach City (pop., 2000: 425,257), southeastern Virginia. It  is situated on the Atlantic Ocean and Chesapeake Bay. Founded in 1887, it  developed as a resort after a railroad was built linking it with Norfolk.  After World War I it became an important base in the national coastal  defense system. In 1963 it and the former Princess Anne county merged  to become the City of Virginia Beach. Its economy is based on tourism  and military installations. Cape Henry Memorial is in the city and the Cape  Henry Lighthouse (1791) is nearby.</p><p>Virginia Company English trading company chartered by James I in  1606 to colonize the eastern coast of North America. Its shareholders were  residents of London. Approximately 105 colonists in three ships reached  Virginia in 1607 and founded Jamestown. The company expanded its ter�  ritory with new charters (1609, 1612) and authorized a two-house legis�  lature (1619), including a House of Burgesses. The colony survived many  hardships, but the company was divided by internecine disputes and was  dissolved in 1624, whereupon Virginia became a royal colony. See also  Plymouth Company.</p><p>Virginia Declaration of Rights Measure adopted by the colony of  Virginia (June 12, 1776). Drafted by George Mason, it stated that �all</p><p>men are by nature equally free and independent and have certain inher�  ent rights� and specified such civil liberties as freedom of the press and  freedom of religion. It became a model for the Bill of Rights.</p><p>Virginia deer See white-tailed deer</p><p>Virgo \'v9r-go\ Latin "Virgin" or "Maiden" In astronomy, the  constellation lying between Leo and Libra; in astrology, the sixth sign of  the zodiac, governing approximately the period August 23-September 22.  Its symbol is a maiden carrying a sheaf of wheat. She has been identified  with fertility goddesses such as Ishtar or with Persephone.</p><p>Virgo cluster Closest large cluster of galaxies at a distance of about 50  million light-years in the direction of the constellation Virgo. About 200  bright galaxies and thousands of faint ones reside in the cluster. In turn,  the Virgo cluster lies at the approximate centre of a larger gravitationally  bound structure, called the Local Supercluster, which also includes the  Local Group of galaxies, to which the Milky Way Galaxy belongs. Near the  centre of the Virgo cluster is the giant elliptical galaxy M87 (or Virgo A),  one of the strongest radio sources in the sky and also a powerful X-ray  source. Images of M87s active galactic nucleus, obtained in 1994, revealed  gas orbiting at such high speeds that astronomers believe a supermassive  black hole must be present.</p><p>virion \'vl-re-,an\ Entire virus particle, consisting of an outer protein shell  (called a capsid) and an inner core of nucleic acid (either RNA or DNA). The  core gives the virus infectivity, and the capsid provides specificity (i.e.,  determines which organisms the virus can infect). In virions whose capsids  are further encased by a fatty membrane, the virion can be inactivated by  exposure to a solvent such as ether or chloroform. Many virions have  capsids with 20 triangular faces and the nucleic acid densely coiled within;  others have capsids consisting of surface spikes, with the nucleic acid  loosely coiled within. Virions of most plant viruses are rod-shaped.</p><p>viroid \'vl-,r6id\ Infectious particle that is smaller than any of the known  viruses. The particle consists of an extremely small circular RNA molecule  that lacks the protein coat of a virus. Viroids appeal - to be transmitted  mechanically from one cell to another through cellular debris. They are  of much interest because of their subviral nature and their unknown mode  of action. Viroids are agents of certain plant diseases; whether they occur  in animal cells is uncertain.</p><p>virology \vl-'ra-l9-je\ Branch of microbiology that deals with the study  of viruses. Viruses were not closely examined until 1892, when a Russian  bacteriologist observed that the agent of tobacco mosaic disease could  pass through a filter that did not permit the passage of bacteria. Modern  virology began in the early 20th century, when the existence of bacterioph�  ages was discovered. Direct visualization of viruses became possible after  the electron microscope was introduced (c. 1940).</p><p>virtual reality Use of computer modeling and simulation to enable a  person to interact with an artificial three-dimensional visual or other sen�  sory environment. A computer-generated environment simulates reality by  means of interactive devices that send and receive information and are  worn as goggles, headsets, gloves, or body suits. The illusion of being in  the created environment (telepresence) is accomplished by motion sen�  sors that pick up the user�s movements and adjust his or her view accord�  ingly, usually in real time. The basis of the technology emerged in the  1960s in simulators that taught how to fly planes, drive tanks, shoot artil�  lery, and generally perform in combat. It came of commercial age in the  1980s and is now used in games, exhibits, and aerospace simulators. It  has potential for use in many fields, including entertainment, medicine  and biotechnology, engineering, design, and marketing.</p><p>virtue Practical dispositions in conformity with standards of excellence  or with principles of practical reason. The seven cardinal virtues of the  Christian tradition include the four �natural,� or cardinal, virtues, those  inculcated in the old pagan world that spring from the common endowment  of humanity, and the three �theological� virtues, those specifically pre�  scribed in Christianity and arising as special gifts from God. The natural  virtues are prudence, temperance, fortitude, and justice; this enumeration,  said to go back to Socrates, is found in Plato and Aristotle. To these St. Paul  added the theological virtues of faith, hope, and love�virtues which, in  Christian teaching, do not originate naturally in humanity but are instead  imparted by God through Christ and then practiced by the believer.</p><p>virtue ethics Approach to ethics that takes the notion of virtue (often  conceived as excellence) as fundamental.

It falls somewhat outside the traditional  dichotomy between deontological ethics and consequentiausm: It agrees  with consequentialism that the criterion of an action�s being morally right  or wrong lies in its relation to an end that has intrinsic value, but more  closely resembles deontological ethics in its view that morally right  actions are constitutive of the end itself and not mere instrumental means  to the end.

Located north of Lake Kivu, it extends for about 50 mi (80 km) along the  borders of Congo (Kinshasa), Rwanda, and Uganda. Of its eight major  volcanic peaks, the highest is Karisimbi, while Nyiragongo is at the west�  ern end of the chain; in 1861 John Hanning Speke was the first European  to spot them. Parts of the range are in Virunga National Park, Volcanoes  National Park (Rwanda), and Gorilla National Park (Uganda).</p><p>Virunga National Park formerly Albert National Park Game  preserve and gorilla sanctuary, northeastern Congo (Kinshasa). Estab�  lished in 1925, it has an area of about 3,050 sq mi (7,900 sq km). Its  southern tip touches the northern shore of Lake Kivu, and much of its cen�  tral region is occupied by Lake Edward. The Virunga Mountains lie  between the two lakes. The park has been a UNESCO World Heritage  Site since 1979.</p><p>virus Microscopic, simple infectious agent that can multiply only in liv�  ing cells of animals, plants, or bacteria. Viruses are much smaller than  bacteria and consist of a single- or double-stranded nucleic acid (DNA or  RNA) surrounded by a protein shell called a capsid; some viruses also have  an outer envelope composed of lipids and proteins. They vary in shape.  The two main classes are RNA viruses (see retrovirus) and DNA viruses.  Outside of a living cell, a virus is an inactive particle, but within an  appropriate host cell it becomes active, capable of taking over the cell�s  metabolic machinery for the production of new virus particles (virions).  Some animal viruses produce latent infections, in which the virus persists  in a quiet state, becoming periodically active in acute episodes, as in the  case of the herpes simplex virus. An animal can respond to a viral infection  in various ways, including fever, secretion of interferon, and attack by the  immune system. Many human diseases, including influenza, the common  cold, and AIDS, as well as many economically important plant and ani�  mal diseases, are caused by viruses. Successful vaccines have been devel�  oped to combat such viral diseases as measles, mumps, poliomyeutis, smallpox,  and rubella. Drug therapy is generally not useful in controlling established  viral infections, since drugs that inhibit viral development also inhibit the  functions of the host cell.

These islands and their smaller neigh�  bours make up the central group of the Ph ilippine archipelago.  Agriculture and fishing are important. The major urban centres are Cebu  City on Cebu and Iloilo City on Panay.</p><p>Visby City (pop., 1994 est.: 21,462), southeastern Sweden. Located on  the northwestern coast of the island of Gotland, it was the site of a Stone  Age settlement c. 2000 bc. By the 12th century ad it was a member of  the Hanseatic League, and in the 13th century it was one of the leading  commercial centres of Europe; the city coined its own money and devel�  oped an international maritime code. It declined after the Danish conquest  of Gotland in 1361. A seaside resort, it has remains of medieval walls.  Because of its remarkably well-preserved medieval ramparts and build�  ings, Visby was designated a protected monument in 1810 and a UNESCO  World Heritage site in 1995.</p><p>viscometer Wis-'ka-mo-toA Instrument for measuring the viscosity  (resistance to internal flow) of a fluid. In one type, the time taken for a  given volume of fluid to flow through an opening is recorded. In the  capillary-tube viscometer, the pressure needed to force the fluid to flow  at a specified rate through a narrow tube is measured. Other types depend  on measurements of the time taken for a sphere to fall through the fluid,  or of the force needed to rotate the inner cylinder of a pair (the space  between the two cylinders being filled with the fluid under test), or of the  rate at which oscillations of a disk vibrating in the fluid die out.</p><p>bacteriophage</p><p>" r otein spikes</p><p>head</p><p>base plate</p><p>RNA</p><p>DNA</p><p>influenza virus</p><p>envelope</p><p>The influenza virus possesses both a protein shell (capsid) and a lipid and protein  envelope. The protein spikes of the envelope facilitate adherence and entry into the  host cell. The capsid proteins determine the influenza virus type (A, B, C), and the  highly variable proteins of the spikes and envelope determine the different strains  within each type. The bacteriophage (bacterial virus) shown here has a head  shaped like an icosahedron (with 20 sides). The tail fibres attach the virus to the  bacterium, bringing the base plate into contact with the surface. The tail contracts,  and DNA from the head is injected into the host.</p><p>� MERRIAM-WEBSTER INC.</p><p>Visconti \ves-'kon-te\, Gian Galeazzo known as Count of Valor</p><p>(b. 1351, Milan�d.

Viscosity  denotes opposition to flow. It may also be thought of as internal friction  between the molecules. Viscosity is a major factor in determining the  forces that must be overcome when fluids are used in lubrication or trans�  ported in pipelines. It also determines the liquid flow in spraying, injec�  tion molding, and surface coating. The viscosity of liquids decreases  rapidly with an increase in temperature, while that of gases increases with  an increase in temperature. The SI unit for viscosity is the newton-second  per square metre (N-s/m 2 ).</p><p>viscount \'vl-,kaunt\ European title of nobility, ranking immediately  below a count, or earl. The wife of a viscount is a viscountess. In the  Carolingian period, the vicecomes were deputies or lieutenants of the  counts {comes), whose official powers they exercised by delegation. In  the 11th century most of Normandy was divided into vicomtes, but the  viscountcy was not introduced into the English peerage until nearly 400  years after the Norman conquest.</p><p>Viscount Melville \'vl- 1 kaunt- , mel- 1 vil\ Sound formerly Melville  Sound Body of water, northern Canada.

Its discovery, when reached from  the east (1819-20) by William E. Parry and from the west (1850-54) by  Robert McClure, proved the existence of the Northwest Passage. The  sound is navigable only under favourable weather conditions.</p><p>vise Device consisting of two parallel jaws for holding a workpiece. One  of the jaws is fixed, and the other can be moved by a screw, lever, or cam.  Vises used for holding a workpiece during hand operations (such as fil�  ing, hammering, or sawing) are usually permanently bolted to a bench.  In vises designed to hold metallic workpieces, the faces of the jaws are  hardened steel plates, often removable, with teeth that grip the workpiece.  Woodworking vises have smooth jaws, often of wood, and rely on fric�  tion alone rather than on teeth.</p><p>Vishnu \'vish-nu\ Principal Hindu deity worshiped as the protector and  preserver of the world and restorer of dharma. He is known chiefly through  his avatars, particularly Rama and Krishna. In theory, he manifests him�  self anytime he is needed to fight evil, and his appearances are innumer�  able, but in practice 10 are most common. His various names, numbering  about 1,000, are repeated as acts of devotion by his worshipers.</p><p>Visigoth Vvi-z3-,gath\ Western division of the Goths. Separated from  the Ostrogoths (Eastern Goths) in the 4th century ad, the Visigoths were  driven from Dacia by the Huns (376) and crossed the Danube into the  Roman empire. Oppressed by Roman taxation, they revolted and plun�  dered the Balkan provinces, defeating Valens and his army at the Battle  of Adrianople (378). Theodosius I settled them in Moesia (382) to defend  the frontier. Converted to Arian Christianity, they left Moesia in 395 under  Alaric and invaded Greece and Italy, sacking Rome (410) and settling in  southern Gaul and Spain (415). Recalled from Spain by Constantius III,  they lost their first king, Theodoric I, in a battle against Attila (451). They  were federates of Rome until King Euric declared independence (475).  He extended their kingdom from the Loire to the Pyrenees and the lower  Rhone, including most of Spain. In 507 they were defeated by the Franks  under Clovis; retaining only Septimania (a strip from the Pyrenees to the  Rhone), they held it and much of Spain until defeated by the Muslims in</p><empty-line/><p>vision See photoreception</p><p>vision, computer See computer vision</p><p>vision quest Essential rite of passage for adolescent boys of the East�  ern Woodlands and Plains Indian peoples.

For him, soul and matter depended on God  for their existence. Exclusive devotion to God can elicit his grace, assist�  ing the devotee in gaining release from the cycle of rebirth. After  Ramanuja, a schism developed over the role of grace, giving rise to dif�  ferent schools. The spread of Visistadvaita was important in the devotional  renaissance of Vaishnavism.

It may be persistent or temporary and shifting, as in a migraine  aura. The field may narrow, as in glaucoma. The normally small blind  spot corresponding to the point where the optic nerve enters the eye can  enlarge if fluid accumulates at that point (papilledema). Methanol or qui�  nine poisoning, diseases of the nerve sheaths, deficiency diseases, and  atherosclerosis can also cause blind spots. Tumours pressing on the optic  nerves in different locations can cause loss of different halves or quarters  of the visual field of each eye.

The term vitamine (1911) was  changed to vitamin when it was realized that not all vitamins are amines  (i.e., not all contain nitrogen). Many vitamins act as or are converted to  coenzymes. They neither provide energy nor are incorporated into tissues.  Water-soluble vitamins (vitamin B complex, vitamin C) are excreted quickly.  Fat-soluble vitamins (vitamin A, vitamin D, vitamin E, and vitamin K) require  bile salts for absorption and are stored in the body. The normal functions  of many vitamins are known. Deficiency of specific vitamins can lead to  diseases (including beriberi, neural tube defect, pernicious anemia, rickets, and  scurvy). Excess amounts, especially of fat-soluble vitamins, can also be  dangerous: e.g., too much vitamin A causes liver damage, an effect not  seen with beta-carotene, which the body converts into vitamin A. Several  vitamins are now known to support the immune system. Most vitamins are  adequately supplied by a balanced diet, but people with higher require�  ments may need supplements.</p><p>vitamin A also called retinol Fat-soluble alcohol, most abundant in  fatty fish and especially in fish-liver oils. It is not found in plants, but  many vegetables and fruits contain beta-carotene (see carotene), which is  readily converted in the body to vitamin A. It functions directly in vision,  especially night vision. A derivative, retinaldehyde, is a component of the  visual pigments, including rhodopsin, in the retina. Humans require vitamin  A in very small amounts. Unlike carotenes, it is toxic in large amounts  and is readily destroyed by exposure to heat, light, or air.</p><p>vitamin B complex Water-soluble organic compounds with loosely  similar properties, distribution in natural sources, and physiological func�  tions. Most are coenzymes, and all appear essential to the metabolic pro�  cesses of all animal life. They include thiamin (B x ), riboflavin (B 2 ), niacin,  vitamin B 6 , pantothenic acid, fouc acid, biotin, and vitamin B 12 (cobal-  amin); some authorities also include choline, carnitine, lipoic acid, inos�  itol, and para-aminobenzoic acid. Vitamin B 6 is needed for metabolism  of amino acids and prevention of skin and nerve disorders. Vitamin B 12  prevents pernicious anemia and is involved in nucleic-acid synthesis, fat  metabolism, and conversion of carbohydrate to fat. The B complex vita�  mins are particularly abundant in cereal grains, meats, nuts, and some  fruits and vegetables.</p><p>vitamin C or ascorbic acid Water-soluble organic compound impor�  tant in animal metabolism. Most animals produce it in their bodies, but  humans, other primates, and guinea pigs need it in the diet to prevent  scurvy. It is essential in collagen synthesis, wound healing, blood-vessel  maintenance, and immunity. Some studies have found a moderate benefit  of vitamin C in reducing the duration and severity of the common cold. It  works as an antioxidant in the body and is used as a preservative. It is  easily destroyed by oxygen. Excellent sources are citrus fruits and fresh  vegetables.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2012 I vitamin D &#x25BA; Vivekananda</p><p>vitamin D Any of a group of fat-soluble alcohols important in calcium  metabolism in animals to form strong bones and teeth and prevent rickets and  osteoporosis. It is formed by ultraviolet radiation (sunlight) of sterols (see  steroid) present in the skin. The most important of these sterols are  7-dehydrocholesterol, formed by metabolic processes in animals, and  ergosterol, present in vegetable oils. The action of sunlight on the skin con�  verts these two compounds, respectively, to cholecalciferol (vitamin D 3 )  and ergocalciferol (vitamin D 2 ). Vitamin D is added to margarine, milk,  and cereals for the benefit of those who may not get enough sunlight in  winter. As little as 5 micrograms each day appeal - adequate for children.  Because the body cannot excrete it, prolonged high intake can cause a toxic  reaction including fatigue, nausea, and abnormal calcium accumulation.</p><p>vitamin E or tocopherol Vto-'ka-fo-.rolX Fat-soluble organic com�  pound found principally in certain plant oils and leaves of green veg�  etables. Vitamin E acts as an antioxidant in body tissues and may prolong  life by slowing oxidative destruction of membranes. Certain rodents require  it for normal reproduction. Besides uses in foods and in nutritional  research and supplements, it is used to retard rancidity in fats, especially  vegetable oils.</p><p>vitamin K Any of several fat-soluble compounds essential for the clot�  ting of blood. A deficiency of vitamin K in the body leads to an increase  in clotting time. In 1929 a previously unrecognized fat-soluble substance  present in green leafy vegetables was found to be required for coagula�  tion of the blood; its letter name comes from the Danish word koagula-  tion. A pure form was isolated and analyzed structurally in 1939; several  related compounds having vitamin-K activity have since been isolated and  synthesized. The form of vitamin K that is important in mammalian tis�  sue is of microbial origin. A synthetic vitamin K precursor called mena�  dione is used as a vitamin supplement.</p><p>Vitellius \vi-'tel-e-3s\, Aulus (b. ad 15�d.

Individuals with vitiligo (about 1% of the adult population) are  usually in good general health, but vitiligo presents a cosmetic problem  that can be serious in dark-skinned individuals. Normal skin color rarely  returns, and there is no known cure.</p><p>Vitoria \ve-'tor-y3\ City (pop., 2002 est.: 299,400), eastern Brazil.  Located on the western side of Vitoria island in Espfrito Santo Bay, it was  founded by the Portuguese in 1535 and was made a provincial capital in  1823. It was Brazil�s leading port for exporting iron ore until the 1960s.  Its economy is based now on textile factories, sugar refineries, and other  small manufacturing plants as well as on the shipment of coffee.</p><p>Vitoria \ve-'tor-e-3\ -Gasteiz City (pop., 2001: 216,852), capital of  Basque Country autonomous community, northeastern Spain. The official  name derives from the combined Spanish (Vitoria) and Basque (Gasteiz)  names for the city. Founded as Victoriacum by the Visigothic king Leovig-  ild in 581, it was granted a charter in the 12th century. In 1200 Alfonso  VIII captured it and incorporated it into his kingdom. In 1813 it was the  scene of a battle in which allied forces under English Gen. Arthur Welle�  sley (later duke of Wellington) defeated the French, driving them from  Spain and leading to the end of the Peninsular War. Now a manufactur�  ing centre, it retains several medieval buildings.</p><p>vitriol, oil of See sulfuric acid</p><p>Vitruvius \v3-'tru-ve-3s\ in full Marcus Vitruvius Pollio (fl. 1st  century bc) Roman architect, engineer, and author of the celebrated trea�  tise De architectural a handbook for Roman architects. Little is known  of his life except what can be gathered from his writings. The treatise is  divided into 10 books covering almost every aspect of architecture and  city planning. His wish was to preserve the Classical Greek tradition in  the design of temples and public buildings, and his prefaces contain many  pessimistic remarks about the architecture of the time. His work was the  chief authority on ancient Classical architecture throughout the antique  revival of the Renaissance, the Classical phase of the Baroque, and the  Neoclassical period.</p><p>Vitsyebsk Vvet-syipsk\ Russian Vitebsk Vve-tipsk\ City (pop., 2001  est.: 349,000), northeastern Belarus. First mentioned in 1021, it was a  major fortress and trading centre and was the chief town of an independent  principality for some 200 years. It passed to Lithuania in 1320, later to  Poland, and then to Russia in 1772. It was destroyed by the Poles in the 16th  century, by the Swedes in the Great Northern War, by Napoleon in 1812,  and by the Germans in World War II. There are two museums dedicated to  Marc Chagall, a native of the city. A major industrial centre, it produces  machine tools, electrical instruments, and a range of consumer goods.</p><p>Vittorini V.vet-'to-'re-neV Elio (b. July 23, 1908, Syracuse, Sicily,  Italy�d. Feb. 13, 1966, Milan) Italian novelist, translator, and critic. He  left school at age 17 and later learned English while working as a proof�  reader. He became, with Cesare Pavese, a pioneer in translating the works  of U.S. and English writers into Italian. His novels of Neorealism mirror  Italy�s experience of fascism and the social, political, and spiritual ago�  nies of the 20th century. Conversation in Sicily (1941), which clearly  expresses his antifascist feelings, is his most important novel.</p><p>Vivaldi \vi-'val-de\ A Antonio (Lucio) (b. March 4, 1678, Venice,  Republic of Venice�d. July 28, 1741, Vienna, Austria) Italian composer.  He was taught violin by his father. In 1703 he was ordained a priest (and  later became known as the �Red Priest� for his red hair). He spent most  of his career teaching violin and leading the orchestra at a Venetian girls�  orphanage. After c. 1718 he became more involved in opera as both com�  poser and impresario. His concertos were highly influential in setting the  genre�s three-movement (fast-slow-fast) form, with a returning theme  (ritornello) for the larger group set off by contrasting material for the  soloists, and he popularized effects such as pizzicato and muting. His  L�estro armonico (1711), a collection of concerti grossi, attracted inter�  national attention. His La stravaganza (c. 1714) was eagerly awaited, as  were its successors, including The Four Seasons (1725). In all he wrote  more than 500 concertos. His most popular sacred vocal work is the Glo�  ria (1708). Though often accused of repeating himself, Vivaldi was in  fact highly imaginative, and his works exercised a strong influence on  Johann Sebastian Bach.</p><p>Vivarini \,ve-va-'re-ne\ family Family of 15th-century Venetian paint�  ers. Antonio Vivarini (b. c. 1415�d. c. 1480) collaborated from 1441 with  his brother-in-law, Giovanni d�Alemagna (d. 1450), on altarpieces, four of  which survive in the churches of San Zaccaria (1443) and San Pantalon  (1444), and on a large three-part canvas in the Accademia (1446). Their  large-scale polyptychs feature stiff, archaic figures and heavily ornamented  frames. In 1447-50 they lived in Padua and worked with Andrea Mantegna  on a cycle of frescoes for the Church of the Eremitani (destroyed in World  War II). Antonio�s younger brother and pupil Bartolomeo (b. c. 1432�d. c.  1499) collaborated with Antonio after 1450. His work, more progressive  than his brother�s, was imitative of Mantegna. From 1459 he worked inde�  pendently. His most distinguished works include the altarpieces in the  churches of SS. Giovanni e Paolo (1473), Santa Maria dei Frari (1474), and  San Giovanni Bragora (1478) and in the Accademia (1477). Antonio�s son  Alvise (b. c. 1445�d. c. 1505) came under the influence of the Bellini family,  with whom he worked on paintings (now lost) for the Doges� Palace  (1488). The overlapping careers of Antonio, Bartolomeo, and Alvise reca�  pitulate the overall development of Venetian painting from the late Gothic  period to the threshold of the High Renaissance.</p><p>Vivekananda Vve-va-ko-'non-doV orig.

He later joined the Brahmo  Samaj and became the most notable disciple of Ramakrishna. By stressing  the universal and humanistic aspects of the Veda and emphasizing service  over dogma, he attempted to infuse vigour into Hinduism. He was a moti-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>vivisection &#x25BA; voice I 2013</p><p>vating force behind the Vedanta movement in the U.S. and England, lec�  turing and proselytizing in both countries. In 1897 he founded the  Ramakrishna Mission, which carries out extensive educational and phil�  anthropic work in India and expounds Vedanta in Western countries.</p><p>vivisection Operation on a living animal for experimental rather than  healing purposes; more broadly, all experimentation on live animals. It is  opposed by many as cruelty and supported by others on the ground that  it advances medicine; a middle position is to oppose unnecessarily cruel  practices, use alternatives when possible, and restrict experiments to nec�  essary medical research (as opposed, for example, to cosmetics testing).  Surgery on animals without anesthesia was once common; many people,  most significantly Rene Descartes, claimed that animals did not really feel  pain. Testing chemicals on animals to find the lethal dose still occurs  despite alternative methods (computer simulations, tissue culture tests). An  anti vivisection movement in the late 19th century broadened its scope to  include prevention of all cruelty to animals and later gave rise to the ani�  mal rights movement.</p><p>vizier Wo-'zir \ Arabic wazTr Chief minister of the �Abbasid caliphs and  later a high government official in various Muslim countries. The office  was originally held and defined by the Barmakids in the 8th century; they  acted as the caliph�s representative to the public, later serving a similar  function for various sultans. In the Ottoman Empire the title could be held  by several people at once; under Mehmed II the position of grand vizier,  the absolute representative of the sultan, was created.</p><p>Vladimir Vvla-do-mar.vla-'de-mirX I, Saint Russian Vladimir  Svyatoslavich (b. 956, Kiev, Kievan Rus�d. July 15, 1015, Bere�  stova, near Kiev; feast day July 15) Grand prince of Kiev (980-1015). He  became prince of Novgorod in 970, and after his father�s death in 972 he  seized Kiev from his brother. He consolidated the Kievan realm from  Ukraine to the Baltic Sea by 980 and fortified its frontiers against Baltic  and Eastern nomads. Originally a pagan, Vladimir made a pact (c. 987)  with Basil II, providing him with military aid in exchange for marriage to  Basil�s sister and promising to convert to Christianity. He adopted the  Byzantine rite for his realm, forcibly converting Kiev and Novgorod and  ordering pagan idols cast into the Dnieper River.</p><p>Vladimir-Suzdal school Vvla-do-msr-'suz-dolV School of Russian  medieval mural and icon painting,  with origins in Kievan Byzantine art,  that flourished in the 12th-13th cen�  tury around the cities of Vladimir  and Suzdal, in northeastern Russia.</p><p>Its works, while maintaining Byzan�  tine illusionistic modeling and solid  proportions that lack the elongation  that characterizes all later Russian  art, move toward a more Russian  expression: the emotion is intensely  ascetic, the anatomy of the figures is  uncertain and the hands are typically  small, and the facial expressions por�  tray a range of emotions. This bril�  liant artistic development ended with  the mid-13th-century Mongol inva�  sions.</p><p>Vladivostok \,vla-d9-v3-'stak,</p><p>.vla-do-'vas-.takV Seaport city (pop.,</p><p>2001 est.: 598,600), southeastern  Russia, in Asia. Founded in 1860 as  a Russian military outpost, it became  the main Russian naval base on the  Pacific Ocean in 1872. It became a  free commercial port in 1904 and  grew rapidly as a military base after  the Russian Revolution of 1917. Dur�  ing the Soviet era it was the home of  the Pacific fleet; its military impor�  tance was such that it was closed to  foreign shipping from the late 1950s. After the collapse of the U.S.S.R.  in 1991, it reemerged as a commercial port, with industries such as ship  repair and fish and meat processing. A cultural centre, it is the eastern  terminus of the Trans-Siberian Railroad.</p><p>"The Archangel Michael," icon by an  anonymous artist of the Vladimir-  Suzdal school, egg tempera on panel,  c. 1300; in the State Tretyakov Gallery,  Moscow</p><p>NOVOSTI PRESS AGENCY, MOSCOW</p><p>Vlaminck Wb-'maqkV Maurice de (b. April 4, 1876, Paris,  France�d. Oct. 11, 1958, Rueil-la-Gadeliere) French painter. Noted for  his brash temperament as well as his flair for landscapes, he began in 1900  to share a studio with Andre Derain, a friend from childhood. In 1905 he  first exhibited at the Salon des Independants. His experiments with pure,  intense colour applied in thick daubs earned him an association with Fau-  VlSM, but by 1908 he had turned to painting landscapes of thickly applied  whites, grays, and deep blues, and his style moved closer to that of Paul  Cezanne. He began c. 1915 to develop a personal, strongly stated style  that placed him solidly in the realm of French Expressionism.</p><p>Vlissingen \'vli-sh]-3\ Seaport city (pop., 2001 est.: 44,776), south�  western Netherlands. As a medieval trading town, its importance lay in  its position controlling the approach to Antwerp. In 1572 it was the first  Netherlands town to rebel against Spanish rule. It was turned into a naval  base by Napoleon during the French occupation (1795-1814). The city  was heavily damaged during World War II, when the area was flooded in  1944 by the Allies to clear the way to Antwerp. Since rebuilt, it is now a  commercial port, fishing harbour, seaside resort, and naval base.</p><p>Vltava Vvol-to-voV River German Moldau River, Czech Republic.  The Czech Republic�s longest river, it flows 270 mi (435 km). The river  rises in southwestern Bohemia from two headstreams in the Bohemian  Forest. It flows first southeast, then north across Bohemia and empties  into the Elbe River.</p><p>Vo Nguyen Giap Vvo-'qui-an-'zyap ,\ English Vvo-en-gi-'en-je-'apN (b.  1912, An Xa, Viet.) Vietnamese military leader. He began to work for  Vietnamese autonomy as a youth and attended the same high school as  Ho Chi Minh. As a professor of history in Hanoi, he converted many col�  leagues and students to his political views. He fled to China in 1939 when  the French banned the Indochinese Communist Party, but returned in  1941. In 1945 he led the Viet Minh forces that defeated the Japanese, who  occupied Vietnam during World War II. He brought French colonial rule  to an end by winning the Battle of Dien Bien Phu (1954) in the First  Indochina War, and he led the North Vietnamese forces that defeated the  U.S. and South Vietnam in the Vietnam War (1955-75). He served in vari�  ous roles in the postwar government of Vietnam until the early 1990s.</p><p>vocal cord Either of two folds of mucous membrane that extend across  the interior cavity of the larynx and are primarily responsible for voice  production. Sound is produced by the vibration of the folds in response  to the passage between them of air exhaled from the lungs. The pitch of  sound varies with the degree of vocal-cord tension. Sounds are then modi�  fied by the tongue, palate, and lips to produce speech. When at rest, the  vocal cords lie apart, forming a V-shaped opening (glottis) through which  air is breathed. The folds located just above the vocal cords are termed  the vestibular or false vocal cords because they are not involved in voice  production. Inflammation (as from excessive use) limits the normal con�  traction of the vocal cords, resulting in hoarseness.</p><p>vodka Colourless distilled liquor of neutral spirits usually made from a  grain mash (generally rye or wheat). Potato vodka originated in Russia in  the 14th century. Today most vodka is distilled from cereal grains. It is  highly neutral, most flavouring substances having been eliminated during  distillation and filtration, the latter process employing charcoal purifiers.  Distilled water is usually added before bottling in order to lower alcohol  content to 40-43% by volume (80-86 proof). Vodka is not aged. It is tra�  ditionally consumed unmixed and chilled, in small glasses; in the U.S.  and elsewhere, it is often used in mixed drinks.</p><p>Vodou \vo-'dlin\ or voodoo National folk religion of Haiti. It com�  bines theological and magical elements of African religions and ritual ele�  ments of Roman Catholicism. Practitioners profess belief in a supreme God  but give more attention to a large number of spirits called the loa, which  can be identified as local or African gods, deified ancestors, or Catholic  saints. The loa demand ritual service and attach themselves to individu�  als or families. In turn, they act as helpers, protectors, and guides. In ritual  services, a priest or priestess leads devotees in ceremonies involving song,  drumming, dance, prayer, food preparation, and animal sacrifice. The loa  possess worshipers during services, dispensing advice, performing cures,  or displaying special physical feats. A well-known aspect of Vodou is the  zombie. See also Macumba; Santeria.</p><p>voice In grammar, the form of a verb indicating the relation between the  participants (subject, object) in a narrated event and the event itself.  English grammar distinguishes between the active voice (�The hunter</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2014 I voice box &#x25BA; Volcker</p><p>killed the bear�) and the passive voice (�The bear was killed by the  hunter�).

Typically, the caller hears a prerecorded message and then has an  opportunity to leave a message in return. The person called can then  retrieve the message at a later time by entering specific codes on his or  her telephone. Voice mail is distinguished from an answering machine by  its ability to provide service to multiple phone lines and by the more  sophisticated functions that it offers in addition to recording messages.</p><p>Voice of America Radio broadcasting network of the U.S. govern�  ment. Its function is to promote understanding of the U.S. and spread  democratic values. Its daily broadcasts include news reports, editorials,  and discussions of U.S. political and cultural events. Its first broadcast,  in German, took place in 1942 to counter Nazi propaganda. By the end  of World War II, it was broadcasting 3,200 programs in 40 languages  every week. During the Cold War it focused its message at the commu�  nist countries of eastern and central Europe. It became part of the U.S.  Information Agency when that agency was formed in 1953.</p><p>voice recognition See speech recognition</p><p>voir dire \'vwar-'dir\ Anglo-French "to speak the truth" In law,  the act or process of questioning prospective jurors to determine whether  they are qualified and suitable for service on a jury.

It covers 8,304 sq  mi (21,506 sq km), and its chief city is Novi Sad. Slavs settled there in  the 6th and 7th centuries, followed by Hungarian nomads in the 9th and  10th centuries. Ottoman Turks controlled the region from the early 16th  to the late 18th century, when it became part of the Austrian Habsburg  empire. By then it was a centre of Serbian Orthodox culture. In 1849 por�  tions of the historic regions of Backa and Banat were united as the Vojvo�  dina under Croatia-Slavonia. In 1867 it reverted to Hungary, and in 1918  it was made part of the Kingdom of Serbs, Croats, and Slovenes (later  Yugoslavia). In 1945 it became an autonomous province of the Serbian  republic, but in 1989 Slobodan Milosevic rescinded this status. In 1999,  after receiving tens of thousands of Serbian refugees from Kosovo, it  demanded restoration of its autonomy. Although denied full autonomy, it  was granted some powers in 2002 by the Serbian parliament.</p><p>volcanic glass Any glassy rock formed from lava or magma that has a  chemical composition close to that of granite. Such molten material may  reach very low temperatures without crystallizing, but its viscosity may  become very high. Because high viscosity inhibits crystallization, the  combination of sudden cooling and loss of volatiles, as when lava extrudes  from a volcanic vent, tends to chill the material to a glass rather than  crystallize it.</p><p>volcanism Vval-ko-.ni-zomX or vulcanism Any of various processes  and phenomena associated with the surface discharge of molten rock or  hot water and steam, including volcanoes, geysers, and fumaroles. Most  active volcanoes occur where two plates converge and one overrides the  other (see plate tectonics). Volcanism can also occur along the axis of an  oceanic ridge, where the plates move apart and magma wells up from the  mantle. A few volcanoes occur within plates, far from margins. Some of  these are thought to occur as a plate moves over a �hot spot� from which  magma can penetrate to the surface; others appear to result from an  extremely slow form of plate spreading.</p><p>volcano Vent in the crust of the Earth from which molten rock, hot rock  fragments, ash, gas, and steam issue. Most volcanoes are found on the  boundaries of the enormous plates that make up the Earth�s surface. Some  of the most violent eruptions take place along convergent boundaries where  one plate margin is forced beneath another. The most famous such bound�  ary is the circum-Pacific belt bordering the Pacific Ocean; the island arcs  and mountain ranges of this �Ring of Fire� have seen gigantic explosions,  among them the eruptions of Mount Pinatubo in the Philippines in 1991,</p><p>Mount Saint Helens in the U.S. state of Washington in 1980, and Krakatoa  (Krakatau) in Indonesia in 1883. Volcanic activity is also common at diver�  gent boundaries, where two plates slowly pull apart and allow molten rock  to escape to the surface; the most prominent example is the Mid-Atlantic  Ridge, site of volcanic islands such as Iceland, the Azores, Ascension, Saint  Helena, and Tristan da Cunha. Yet another type of volcanic activity is found  on the island of Hawaii, located on a �hot spot� near the middle of the  Pacific Plate where plumes of partially melted rock rise from below the  Earth�s crust; there the volcanoes Kilauea and Mauna Loa frequently eject  streams and fountains of lava. Some of the best-known volcanism takes  place around the Mediterranean Sea, where the eruptions of Mount Etna,  Vesuvius, the islands of Stromboli and Vulcano, and other volcanoes have  been observed for millennia. Some volcanoes have cultural or religious sig�  nificance for the peoples around them; these include Misti Volcano in Peru,  Mount Fuji in Japan, and Ol Doinyo Lengai in Tanzania.</p><p>A volcano forms when magma beneath the Earth's crust forces its way to the sur�  face. Alternating layers of solidified lava and pyroclastic materials (ash and cin�  ders) build up the typical cone shape of a stratovolcano as they are ejected through  the central vent during eruptions.</p><p>� MERRIAM-WEBSTER INC.</p><p>Volcano Islands Japanese Kazan-retto or lo-rettd Group of  three small volcanic islands, western Pacific Ocean. Administratively part  of Japan, they lie south of the Bonin Islands. After they were visited by  Japanese fishermen and sulfur miners in 1887, the three islands of Kita  16, 16 (Iwo Jima; the largest), and Minami 16 were claimed by Japan in  1891. 16 was the scene of heavy fighting during World War II. After the  war Japan retained residual sovereignty over the islands, but the U.S.  administered them from 1951 until they were returned to Japan in 1968.</p><p>volcanology or vulcanology Scientific discipline concerned with  all aspects of volcanic phenomena. Volcanology deals with the formation,  distribution, and classification of volcanoes, as well as their structure and  the kinds of materials ejected during an eruption (e.g., lava, dust, ash, and  gas). It also involves research on the relationships between volcanic erup�  tions and other large-scale geologic processes, such as mountain building  and earthquakes. One of its chief aims is to determine the nature and  causes of volcanic eruptions in order to predict them. Another practical  concern is obtaining data that may aid in locating commercially valuable  deposits of ores, particularly those of certain metallic sulfides.</p><p>Volcker, Paul A(dolph) (b.

To end a period of very high  inflation, he slowed the growth of the money supply and allowed interest  rates to rise, causing a recession (1982-83) but dramatically reducing  inflation.</p><p>vole Any burrowing rodent (family Cricetidae) with a blunt snout, small  ears, and short limbs. Most species  are herbivorous and are found  throughout North America and Eur�  asia. The approximately 45 species  of the genus Microtus, also called  meadow mice, are 4-10 in. (10-26  cm) long, including the tail. Their  long, shaggy fur is grayish brown.</p><p>About 10 species of pine voles  inhabit swamps, fields, and hard�  wood forests.

Located on the  Volga River, it was founded as the fortress of Tsaritsyn in 1589. During  the Russian Civil War (1918-20), Joseph Stalin organized the city�s defense  against the White Russian armies, and it was later renamed in his honour.  During World War II it was reduced to rubble in the Battle of Stalingrad;  it was rebuilt in the postwar era. Its manufactures include steel and alu�  minum, engineering products, timber goods, building materials, and food�  stuffs. A major railroad junction and river port, it is the eastern terminus  of the Volga-Don Ship Canal.</p><p>Volhynia \val-'hi-ne-o\ Historical region, northwestern Ukraine.  Located around the headstreams of the Pripyat and Bug rivers, it originally  was a Russian principality (10th-14th century), west of Kiev. In the 14th  century it became part of the Grand Duchy of Lithuania but was ruled  largely by its own aristocracy. It passed to Poland in 1569. In 1793 it was  transferred to Russia under the second partition of Poland. The Treaty of  Riga (1921) divided it between Poland and the U.S.S.R. The U.S.S.R. took  the Polish section in 1939 and made it part of the Ukrainian S.S.R. after  World War II.</p><p>Volkswagen AG (VW) Major German automobile manufacturer. It  was founded in 1937 to mass-produce a low-priced �people�s car� ( Volks�  wagen ). After World War II the company was rebuilt with Allied help,  and within a decade it was producing half of West Germany�s motor  vehicles. U.S. sales of the small, rounded car were initially low, but a  humorous advertising campaign promoting the car as �the Beetle� lifted  sales in the 1960s, making it the leading auto import in the U.S. Com�  petition from other foreign compact cars brought VW near bankruptcy by  1974, but the firm rebounded by introducing sportier models such as the  Rabbit. In 1998 it launched a fully redesigned version of the Beetle. With  its affiliates, VW operates plants worldwide; it also owns other auto  brands, including Audi and Bentley.</p><p>volleyball Game played by two teams of six players each, in which an  inflated ball is volleyed over a high net. Each team tries to make the ball  touch the court within the opposing side�s playing areas before it can be  returned. A team is allowed to touch the ball three times before returning  it. The team that first scores 15 points wins the game. Volleyball was  invented in 1895 by William G. Morgan in Holyoke, Mass. It soon proved  to have wide appeal for both sexes in schools, playgrounds, the armed  forces, and other settings. International competition began in 1913, and  volleyball became an Olympic sport in 1964. Beach volleyball, a varia�  tion with two players on a side, has grown increasingly popular and  became an Olympic sport in 1996.</p><p>Volsci Vvol-ske, 'val-,sl\ Ancient Italic people prominent in the history  of Roman expansion in the 5th century bc. They belonged to the Osco-  Sabellian group of tribes and lived (c. 600 bc) in the valley of the upper  Liris River (then in southern Latium). They fought the Romans and the  Latins intermittently for about 200 years. The Romans established several  colonies to stem the Volsci advance. In 340 they joined the Latin revolt  against Rome but were defeated. After submitting to Rome by 304, they  quickly became fully Romanized.</p><p>Volstead Act See Prohibition</p><p>Vplsunga saga Vvoel-surj-o, 'vol-suq-oV (�Saga of the Volsungs�) Best  of the Icelandic sagas known as fornaldar sQgur (�sagas of antiquity�).  Dating from roughly 1270, it is the first of the fornaldar SQgur to have  been written down. It contains the Northern version of the story told in  the Nibelungenued. The saga was based on the heroic poems in the Poetic  Edda and is especially valuable because it preserves in prose form some  of the poems from the Edda that were lost. It became one of the sources  of Richard Wagner�s operatic Ring tetralogy.</p><p>Volta Vvol-toV Alessandro (Giuseppe Antonio Anastasio) (b.</p><p>Feb. 18, 1745, Como, Lombardy�d. March 5, 1827, Como) Italian sci�  entist. In 1775 he invented the electrophorus, a device used to generate  static electricity. He taught physics at the University of Pavia (1779-  1804). After Luigi Galvani in 1780 produced an electric current by con�  necting two different metals with the muscle of a frog, Volta began  experimenting in 1794 with metals alone and found that animal tissue was  not needed to produce current. He demonstrated the first electric battery  in 1800. In 1801 he demonstrated the battery�s generation of current  before Napoleon, who made him a count and senator of the kingdom of  Lombardy. In 1815 he was appointed director of the philosophical faculty  at the University of Padua. The volt was named in his honour in 1881.</p><p>Volta, Lake Lake, Ghana. One of the world�s largest artificial lakes, it  was formed in 1965 when the Akosombo Dam dammed the Volta River  and created a reservoir that extends about 250 mi (400 km) upstream to  beyond the former confluence of the Black Volta and White Volta rivers.  It covers 3,283 sq mi (8,502 sq km), or 3.6% of Ghana�s area. It is a  major fishing ground and provides irrigation water for farmland in the  Accra plains. The dam generates enough hydroelectric power to supply  most of Ghana�s electricity needs.</p><p>Volta Vval-ts, 'vol-t3\ River River, Ghana, western Africa. The nation�s  chief river, it flows from Lake Volta and receives the Black Volta and the  White Volta rivers. It flows southward through Ghana to the Bight of Benin  in the Gulf of Guinea.

May 30, 1778, Paris) French writer. Voltaire studied law  but abandoned it to become a writer. He became acclaimed for his trag�  edies and continued to write for the theatre all his life. He was twice  imprisoned in the Bastille for his remarks and in 1726 was exiled to  England, where his philosophical interests deepened; he returned to  France in 1728 or 1729. His epic poem La Henriade (1728) was well  received, but his lampoons of the Regency and his liberal religious opin�  ions caused offense. Lettres philosophiques (1734), in which he spoke out  against established religious and political systems, created an uproar. He  fled Paris and settled at Cirey in Champagne with Mme du Chatelet, who  became his patroness and mistress, and there he turned to scientific  research and the systematic study of religions and culture. After her death  he spent periods in Berlin and Geneva; in 1754 he settled in Switzerland.  In addition to his many works on philosophical and moral problems, he  wrote contes (�tales�) including Zadig (1747), Micromegas (1752), and  his best-known work, Candide (1759), a satire on philosophical optimism.</p><p>Meadow vole (Microtus pennsylvani-  cus).</p><p>JUDITH MYERS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2016 I Volturno River &#x25BA; Voting Rights Act</p><p>He kept up an immense correspondence and took an interest in any cases  of injustice, especially those resulting from religious prejudice.

It flows  southeast from the Abruzzese Apennines, then turns west to empty into the  Gulf of Gaeta. It is 109 mi (175 km) long and has a dam for flood con�  trol and irrigation. During the wars for Italian unity, the Italian national�  ist leader Giuseppe de Garibaldi defeated a Neapolitan army there in 1860.  During World War II, German forces in southern Italy used it as their line  of defense after the fall of Naples; after severe fighting, the Allies crossed  the river in October 1943.</p><p>volume See length, area, and volume</p><p>voluntarism Vva-lon-to-.ri-zonA Metaphysical or psychological system  that assigns a more predominant role to the will (Latin, voluntas ) than to  the intellect. Christian philosophers who have been described as volun�  tarist include St. Augustine, John Duns Scotus, and Blaise Pascal. A meta�  physical voluntarism was propounded in the 19th century by Arthur  Schopenhauer, who took will to be the single, unconscious force behind  all of reality and all ideas of reality. An existentialist voluntarism was  present in Friedrich Nietzsche�s doctrine of the overriding �will to power�  whereby man would eventually recreate himself as �superman.� And a  pragmatic voluntarism is evident in William James�s conception of knowl�  edge and truth in terms of purpose and practical ends.</p><p>vomiting Forcible ejection of the stomach contents from the mouth,  usually following nausea. Causes include illness, motion sickness, certain  drugs, inner ear disorders, and head injury. Vomiting may occur without  nausea (e.g., after extreme exertion). Two centres in the brain�s medulla  oblongata are believed to control it; the vomiting centre initiates and con�  trols a series of muscle contractions beginning at the small intestine and  moving through the stomach and esophagus. This reaction may be set off  by the chemoreceptor trigger zone, stimulated by many toxins and drugs,  to rid the body of them, or by stimuli from various parts of the body that  may be stressed or diseased. Severe vomiting may cause dehydration,  malnutrition, or esophageal wall rupture. Vomiting of blood may be a sign  of bleeding ulcer or other upper digestive tract disorders.

After receiving his Ph.D. from  the University of Budapest, he emigrated to the U.S. to teach at Prince�  ton University (1930) and was among the original faculty of the Institute  for Advanced Study (from 1933). He solved one of David Hilbert�s 23  theoretical problems and collaborated on developing an algebraic ring  with profound applications in quantum physics. During World War II he  participated in the development of the atomic bomb. After the war he made  major contributions to the development of high-speed computers; one of  his computers was essential to the creation of the hydrogen bomb. As coau�  thor of Theory of Games and Economic Behavior (1944), he was one of  the founders of game theory.</p><p>Vondel Vvon-dolV Joost van den (b. Nov. 17, 1587, Cologne�d.  Feb. 5, 1679, Amsterdam) Dutch poet and dramatist. Of Mennonite par�  ents, Vondel early showed a preference for using Christian mythology as  the subject matter of his plays. He also wrote lampoons and satirical  poems against the Dutch church and government. His dramatic tragedies,  with their lyrical language and grandeur of conception, are his most  important achievement. The Passover (1612) is his most notable early  work. He first modeled his plays on ancient Latin drama but later turned  to the Greek model; plays of the latter type include his masterpiece, the  trilogy comprising Lucifer (1654), Adam in Exile (1664), and Noah  (1667), which influenced John Milton�s Paradise Lost.</p><p>Vonnegut Wa-ns-.gatV, Kurt, Jr. (b.

Captured by the Germans during World War II, he also survived  the Allied firebombing of Dresden, an experience he made part of his  novel Slaughterhouse-Five (1969; film, 1972). His pessimistic and satiri�  cal novels use fantasy and science fiction to highlight the horrors and iro�  nies of 20th-century civilization. They include Player Piano (1952), Cat�s  Cradle (1963), Breakfast of Champions (1973), Galapagos (1985), and  Timequake (1997). He also wrote plays and collections of short stories.</p><p>voodoo See vodou</p><p>Voronezh Wo-'ro-nishX City (pop., 2001 est.; 901,800), western Russia.  It lies along the Voronezh River above its confluence with the Don. It was  founded in 1586 as a fortress. Peter I (the Great) built a naval flotilla in  Voronezh for use in his campaigns against the Turks. With the agricul�  tural development of the region, it became a centre for the grain trade.  Occupied by the Germans and largely destroyed in World War II, it was  rebuilt in the postwar era. It has a range of engineering, chemical, and  food-processing industries. Its university was established in 1918.</p><p>Vorontsov Wo-ront-'sofX, Mikhail (Illarionovich) (b. July 23,  1714�d. Feb. 26, 1767, St. Petersburg, Russia) Russian statesman. A  member of a family that became prominent in Russian court circles in the  18th century, he was appointed a page in the court of Yelizaveta Petrov�  na (later Elizabeth) at the age of 14. In 1742 he helped her overthrow Tsar  Ivan VI and become empress. As Elizabeth�s vice chancellor (1744-58)  and chancellor (1758-62), he played a major role during her reign, espe�  cially in his pro-French foreign policy. When Peter III succeeded Elizabeth  and abandoned her alliances with France and Austria, Vorontsov made no  effort to dissuade the new emperor and even continued to support him  when he was deposed by his wife, Catherine II (1762). Vorontsov was con�  sequently placed under house arrest; only after Peter died did he swear  allegiance to Catherine and resume his office as chancellor, which he held  until he retired in 1763.</p><p>Voroshilov X.vor-o-'she-.loA, Kliment (Yefremovich) (b.

A notable military commander in World  War I and later in the Russian Civil War, he led the defense of Tsaritsyn  (now Volgograd). A close associate of Joseph Stalin, he was appointed peo�  ple�s commissar for defense (1925) and a member of the Politburo (1926).  Named a marshal of the Soviet Union (1935), he reorganized the Soviet  general staff, mechanized the army, and developed the air force. After the  initial Soviet defeats in World War II, he was removed as defense commis�  sar but appointed to the committee for state defense (1941-44). He later  chaired the Presidium of the Supreme Soviet (1953-57).</p><p>Vorster Vfor-storV John orig. Balthazar Johannes Vorster (b.</p><p>Dec. 13, 1915, Jamestown, Cape Province, S.Af.�d.

In the 1948 elections he  was rejected by the National Party as too extreme, but his support grew  in the 1950s. As minister of justice (1961-66) under Hendrik Verwoerd, he  rigidly enforced apartheid. When Verwoerd was assassinated, Vorster was  chosen to replace him. In the 1970s he sent troops into Angola against its  Soviet- and Cuban-supported government. He resigned in 1978 and took  the ceremonial post of president, but a scandal forced his resignation.</p><p>Vorticism Vvor-ti-.si-zomV Literary and artistic movement that flour�  ished in England 1912-15. Founded by Wyndham Lewis, it attempted to  relate art to industrialization. It opposed 19th-century sentimentality and  extolled the energy of the machine and machine-made products, and it  promoted something of a cult of sheer violence. In the visual arts, Vor-  ticist compositions were abstract and sharp-planed, showing the influence  of Cubism and Futurism. Artists involved in the movement included the poet  Ezra Pound and the sculptor Jacob Epstein.</p><p>Vortsjarv Vvorts-.yarvV or Vorts Jarv Lake, south-central Estonia.

His early work was influenced  by Caravaggio, but works done after 1620 display more idealized figures  and use more evenly diffused white light. He returned to Paris in 1627 to  become first painter to Louis XIII. Thereafter he won almost all the impor�  tant commissions and dominated the city artistically for the next 15 years.  He introduced the Italian Baroque style in France with such paintings as  St. Charles Borromeo (c. 1640). His late works display the soft, idealized  modeling, sensuous forms, and bright colours for which he is best known.</p><p>vowel Speech sound in which air from the lungs passes through the  mouth with minimal obstruction and without audible friction, like the i  in fit. The word also refers to a letter representing such a sound ( a , e, i,  o, u, and sometimes y). In articulatory phonetics (see articulation), vowels  are classified by tongue and lip position; for example, high vowels like  the i in machine and the u in flute are both pronounced with the tongue  arched high in the mouth, but in u the lips are also rounded. Single vowel  sounds are monophthongs; two vowel sounds pronounced as one syllable,  like the ou in round, are diphthongs.</p><p>Voyager Either of two unmanned U.S. interplanetary probes launched  in 1977 to gather information about the Sun�s outer planets. Voyager 1  flew by Jupiter in 1979 and reached Saturn in 1980. Voyager 2 traveled  more slowly, flying by Jupiter, Saturn, and Uranus to reach Neptune in  1989. Data and photographs from both probes revealed new details about  these giant planets, their moons, and their rings. In 1998 Voyager 1  became the most distant human-made object in space (overtaking Pioneer  10). Both Voyagers were expected to remain operable through the first or  second decade of the 21st century, periodically transmitting data on the  HELIOPAUSE.</p><p>Voyageurs \,vwa-ya-'zh3r\ National Park National park, northern  Minnesota, U.S. Located along the Canadian border, the park was estab�</p><p>lished in 1975 and was named for the  mostly French-Canadian fur-trading  frontiersmen (voyageurs) of the  18th�19th centuries.

His child�  hood experience of World War II was  later vividly reflected in poems such  as �Goya� (1960), one of his best-  known works. He became a protege  of Boris Pasternak and a star attrac�  tion at poetry readings until a 1963  Soviet crackdown on �excessively  experimental� artists and writers. He  later returned to partial favour. His  most characteristic poems are apo�  litical celebrations of art, freedom,  and the unrestrained human spirit.

He received numerous commissions to decorate public buildings, includ�  ing murals in the Palais de Chaillot (1937) and in the League of Nations  building in Geneva (1939), and also designed for the Ballets Russes.</p><p>Vulcan Ancient Roman god of fire. He was the counterpart of the Greek  Hephaestus. Vulcan was especially associated with the destructive aspects  of fire, such as volcanoes or conflagrations, and for this reason his temples  were usually located outside the city.

Often invoked to avert fire, he was addressed with epithets  such as Mulciber (�Fire Allayer�).</p><p>Vulcan Hypothetical planet within the orbit of Mercury. It was predicted  in 1859 by Urbain-Jean-Joseph Le Verrier (1811-77) to account for an  unexplained component of the precession of Mercury�s orbit. Sightings  were reported between 1859 and 1878, but these were not confirmed sub�  sequently by observations made either during solar eclipses or when the  planet was predicted to cross the Sun. The anomalies of Mercury�s orbit  were later explained by Albert Einstein�s general theory of relativity.</p><p>vulcanism See volcanism</p><p>vulcanization Chemical process, discovered by Charles Goodyear  (1839), by which the physical properties of natural or synthetic rubber are  improved.

Sup�  ported by the Radical Republicans, the bill called for provisional military  government of the seceded states, an oath of allegiance from a majority  of the state�s whites, and new state constitutions that would abolish sla�</p><p>very and disqualify Confederate officials from holding office. Lincoln  considered the bill too harsh and allowed it to expire by using a pocket  veto.</p><p>wage-price control Setting of government guidelines to limit  increases in wages and prices. It is one of the most extreme approaches to  incomes policy. By controlling wages and prices, governments hope to  control inflation and prevent extremes in the business cycle. Countries with  highly centralized methods of setting wages tend to have the greatest  degree of public or collective regulation of wage and price levels. For  example, wage settlements in The Netherlands must be approved by the  government, and price increases are investigated by the Ministry of Eco�  nomic Affairs. Other countries, including  the U.S., have also made efforts at  restraining wage and price increases, usu�  ally seeking the voluntary cooperation of  management and labour. In the U.S., wage-  price controls were instituted by Pres. Franklin  D. Roosevelt during World War II and by Pres.  Richard M. Nixon in the early 1970s, when high  inflation combined with rising unemployment to  create instability.</p><p>Wagner \'wag-nor\, Honus orig. John Peter  Wagner (b. Feb. 24, 1874, Mansfield, Pa.,  U.S.�d. Dec. 6, 1955, Carnegie) U.S. baseball player.  Wagner played principally for the Pittsburgh Pirates  (1900-17) and coached the team from 1933 to 1951.  The right-handed hitter led the National League in bat�  ting average in eight seasons (1900, 1903-04, 1906-09,  1911) and in stolen bases five seasons. His total of 252  three-base hits remains a National League record. Nick�  named the �Flying Dutchman� for his speed, Wagner is considered one  of the greatest shortstops and all-around players in baseball history.</p><p>Wagner Vvag-norV, Otto (b. July 13, 1841, Penzing, near Vienna,  Austrian Empire�d. April 11, 1918, Vienna) Austrian architect and  teacher. In 1893 his general plan (not executed) for Vienna won a major  competition, and in 1894 he was appointed professor at the Akademie der  Bildenden Kiinste. As a teacher, Wagner soon broke with tradition by  insisting on function, material, and structure as the bases of architectural  design. Among his notable buildings, all in the Art Nouveau style, are a  number of stations for the City Railway of Vienna (1894�97) and the  Postal Savings Bank (1904-06). The latter, which had little decoration,  is recognized as a milestone in the history of modern architecture, par�  ticularly for the curving glass roof of its central hall. Wagner�s lectures  were published in 1895 as Moderne Architektur.</p><p>Wagner Vvag-narV, (Wilhelm) Richard (b. May 22, 1813, Leipzig,  Ger.�d. Feb. 13, 1883, Venice, Italy) German composer. His childhood  was divided between Dresden and Leipzig, where he had his first com�  position lessons; his teacher refused payment because of his talent. His  first opera, The Fairies (1834), was followed by The Ban on Love (1836);  the premiere performance was so unprepared that the event was a fiasco,  and he henceforth determined not to settle for modest productions. The  success of Rienzi (1840) led him to be more adventurous in The Flying  Dutchman (1843) and even more so in Tannhauser (1845). Caught up in  the political turmoil of 1848, he was forced to flee Dresden for Zurich.  During this enforced vacation, he wrote influential essays, asserting (fol�  lowing G.W.F. Hegel) that music had reached a limit after Ludwig van  Beethoven and that the �artwork of the future� would unite music and the�  atre in a Gesamtkunstwerk (�total artwork�). In 1850 he saw Lohengrin  produced. He had begun his most ambitious work. The Ring of the Nibe-  lung, a four-opera cycle. The need for large-scale unity brought him to  the concept of the leitmotiv. He ceased work on the Ring�s third opera,  Siegfried, in the throes of an adulterous love with Mathilde Wesendonk  and wrote an opera of forbidden love, Tristan und Isolde (1859), which  also seemed to break the bonds of tonality. He published the Ring libret�  tos in 1863, with a plea for financial support, and Louis II of Bavaria  responded, inviting Wagner to complete the work in Munich. From the  late 1860s to the early 1880s, Wagner completed work on Die Meisters-  inger, Siegfried, Gotterddmmerung, and the long-deferred Parsifal, as he  also oversaw the building of the great festival theatre at Bayreuth (1872�  76) that would be dedicated to his operas. His astonishing works made  Wagner one of the most influential and consequential figures in the his�  tory of Western music and, indeed, of Western culture. In the late 20th</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2020 I Wagner &#x25BA; Waite</p><p>century his undoubted musical stature was challenged somewhat by the  strongly racist and anti-Semitic views expressed in his writings, and evi�  dence of anti-Semitism in his operas was increasingly documented.</p><p>Wagner Vwag-norV Robert F(erdinand) (b. June 8, 1877, Nastat-  ten, Hesse-Nassau, Ger.�d. May 4, 1953, New York, N.Y., U.S.) U.S.  politician. He immigrated with his family to New York City in 1885. He  became active in Democratic Party politics, serving in the state legisla�  ture (1904-19) and as a justice of the state court of appeals (1919-26).  In the U.S. Senate (1927�49), he became an ally of Pres. Franklin D.  Roosevelt and introduced New Deal labour and social-reform legislation,  including the National Industrial Recovery Act (1933), the National Labor  Relations Act (known as the Wagner Act), and the Social Security Act. He  cosponsored the Wagner-Steagall Act (1937), which created the U.S.  Housing Authority. His son, Robert F. Wagner, Jr. (1910-91), served as  mayor of New York (1954-65).</p><p>Wagner Act or National Labor Relations Act (1935) Labour  legislation passed by the U.S. Congress. Sponsored by Sen. Robert F.  Wagner, the act protected workers� rights to form unions and to bargain  collectively. A three-member National Labor Relations Board was estab�  lished to protect against unfair labour practices; it could order elections  to allow workers to choose which union they wanted to represent them.  The act also prohibited employers from engaging in unfair labour prac�  tices such as setting up a company union and firing or otherwise discrimi�  nating against workers who organized or joined unions. The act,  considered the most important piece of labour legislation in the 20th cen�  tury, helped ensure union support for Pres. Franklin D. Roosevelt in the  1936 election.</p><p>Wagner-Jauregg Vvag-nor-'yau-rekV Julius orig. Julius Wag�  ner, knight von Jauregg (b. March 7, 1857, Weis, Austria�d. Sept.  27, 1940, Vienna) Austrian psychiatrist and neurologist. Knowing that  malaria could be controlled with quinine and having observed that patients  with some nervous disorders improved after infections with fever, he  induced malaria to treat syphilis patients who had central nervous system  disorders. For thus controlling an incurable fatal disease, he was awarded  a 1927 Nobel Prize. Though antibiotics replaced this treatment for syphi�  lis, it led to the development of fever therapy.</p><p>wagon Four-wheeled vehicle designed to be drawn by draft animals.  Wagons have been used from the 1st century bc; early examples used  spoked wheels with metal rims, pivoted front axles, and linchpins to  secure the wheels. Ninth-century improvements in suspension made the  wagon preferable to the two-wheeled cart, especially for carrying freight  and agricultural produce.</p><p>Wagram \'va-,gram. Battle of (July 5-6, 1809) Victory by French  forces under Napoleon against Austria. In an attempt to break French  control of Germany, Austria�s 158,000 troops under Archduke Charles  (1771-1847) were deployed along a 14-mi (23-km) front on either side  of the village of Wagram, near Vienna. The attack by Napoleon and his  154,000 French troops split the centre of the Austrian line. By the time  reinforcements arrived, Charles�s army was in retreat, and four days later  he asked for an armistice. Heavy use of artillery (the heaviest in any war  to that time) caused more than 40,000 Austrian casualties and about  34,000 French.</p><p>wagtail Any of 7-10 passerine species in the genus Motacilla and the  forest wagtail ( Dendronanthus indi-  cus) of Asia. Wagtails continually  pump their long tail up and down;  the forest wagtail wags its entire  body from side to side. They inhabit  beaches, meadows, and streamsides,  nesting on the ground and roosting in  trees. Males of the white, or pied,  wagtail (M. alba), common across  Eurasia, are white and gray or white  and black. The only New World spe�  cies, the yellow wagtail (M. flava ),  breeds in Alaska and migrates to  Asia.</p><p>Wahhab \wa-'hab\, Muham�  mad ibn ( Abd al- (b. 1703,  �Uyaynah, Arabia�d. 1792,</p><p>Gray wagtail (Motacilla cinerea).</p><p>H.

He  reacted against what he perceived as the extremism of various sects of  Sufism, setting out his ideas in the Book of Unity (1736). He stressed a  conservative observation of Islam, rejecting polytheism and condemning  reverence of saints and the decoration of mosques. His views were con�  troversial; eventually he settled in Nejd, where, in alliance with Ibn Sa'ud,  his teachings found favour and grew dominant.</p><p>Wahhabi \wa-�hab-e\ Member of a Muslim puritan movement founded  in the 18th century by Muhammad ibn c Abd al-Wahhab. Members call them�  selves al-Muwahhidun, a name derived from their emphasis on the abso�  lute oneness of God. They reject all acts implying polytheism, including  the veneration of saints, and advocate a return to the original teachings  of Islam as found in the Qu�ran and the HadIth. They supported the estab�  lishment of a Muslim state based on Islamic canon law. Adopted by the  ruling Saudi family in 1744, the movement controlled all of Nejd by the  end of the 18th century. It was assured of dominance on the Arabian Pen�  insula with the creation of the kingdom of Saudi Arabia in 1932, and in  the 20th century�supported by Saudi wealth�it engaged in widespread  missionary work throughout the Islamic world.</p><p>wahoo Vwa-.hiA Species ( Acanthocybium solanderi) of swift-moving,  powerful, predaceous food and game fish found worldwide, especially in  the tropics.

Wakan can be conceived  of as weak or strong powers; the weak can be ignored but the strong must  be placated. Wakan beings are the immortal supernatural powers who  bestow wakan; they too may be weak or strong, but are all believed to  enjoy music and smoke from pipes. Poisonous plants and reptiles can  contain wakan, as can intoxicating drinks. The concept of wakan is simi�  lar to that of MANA.</p><p>Wakatipu \,wa-k3-'te-pu\ Lake Lake, south-central South Island, New  Zealand.

An unincorporated territory  of the U.S., Wake Island comprises three low-lying coral islets (Wilkes,  Peale, and Wake) that surround a lagoon and occupy a total land area of  2.5 sq mi (6.5 sq km). The atoll was claimed by the U.S. in 1899. In 1935  it became a stopover for transpacific commercial flights. The U.S. Navy  began construction of an air and submarine base in 1939, which was half-  completed when Wake was attacked and occupied by Japanese forces in  December 1941. After the Japanese surrendered (1945), Wake was admin�  istered by the U.S. Air Force. Commercial flights resumed, but by 1974  Wake was being used as an emergency stopover. It is also the site of  weather research stations. There is no indigenous population on the island,  but there is a small contingent of civilian workers.</p><p>Wakefield City and metropolitan borough (pop., 2001: 315,173),  southeastern portion of the metropolitan county of West Yorkshire, historic  county of Yorkshire, England. Originally part of a royal manor, it became  a baronial holding after 1086. It was the scene of the Wars of the Roses  at which Richard, duke of York, was captured and beheaded by Lancas�  trians. In the 15th century the Wakefield Plays, one of the collections of  English miracle plays, were presented there. The town was attacked and  taken by the Parliamentarian general Baron Fairfax in 1643 during the  English Civil Wars. Known as a textile centre since the 16th century, Wake�  field specializes in wool and synthetic knitting yams.</p><p>Wakefield, Edward Gibbon (b. March 20, 1796, London, Eng.�d.  May 16, 1862, Wellington, N.Z.) British colonizer of South Australia and  New Zealand. After viewing the problems of the penal system, including  the forcible removal of convicts to British colonies, he wrote A Letter  from Sydney (1829) and proposed colonization by the sale of small land-  holdings to ordinary citizens. He influenced the founding of South Aus�  tralia as a nonconvict settlement. As organizer and manager of the New  Zealand Company (1838-58), he sent colonists to settle New Zealand and  forced the British government to recognize the colony. As an adviser to  the earl of Durham, he influenced the report that led to the union of Upper  and Lower Canada. He founded a Church of England settlement at Can�  terbury, N.Z. (1847).</p><p>Waksman, Selman (Abraham) (b. July 22, 1888, Priluka,  Ukraine, Russian Empire�d. Aug. 16, 1973, Hyannis, Mass., U.S.)  Ukrainian-born U.S. biochemist. He became a U.S. citizen in 1916 and  spent most of his career at Rutgers University. After the discovery of  penicillin, he played a major role in initiating a calculated, systematic  search for antibiotics (a term he coined in 1941) among microorganisms.  His 1943 discovery of streptomycin, the first specific agent effective in  the treatment of tuberculosis, brought him a 1952 Nobel Prize. Waksman</p><p>also isolated and developed several other antibiotics, including neomycin,  that have been used in treating many infectious diseases of humans,  domestic animals, and plants.</p><p>Walachia \wa-'la-ke-9\ Former principality, south-central Europe. It lay  between the Danube River and the Transylvanian Alps in what is now  Romania. It was founded in 1290 by Radu Negru, a vassal of Hungary,  and achieved independence from Hungary in 1330. The capital from the  14th to the 17th century was Targoviste. Walachia was ruled by the Turks  in the 15th century, though some princes resisted, notably Vlad II Dracul  (1436-47) and Vlad III Tepe�, who are often cited as the historical bases  for the Dracula vampire tales. Walachia briefly annexed Moldavia and  Transylvania in the late 16th century. Russian influence grew in the 18th  century, and in 1774 Walachia came under Russia�s protection, though it  continued to recognize Turkish suzerainty. Russia�s protectorate ended  after the Crimean War, and in 1859 Walachia united with Moldavia to form  Romania.</p><p>Walcott Vwol-.katV, Derek (Alton) (b. Jan. 23, 1930, Castries, Saint  Lucia) West Indian poet and playwright. Of mixed black, Dutch, and  English descent, Walcott was educated in Saint Lucia and Jamaica. After  1958 he lived in Trinidad and the U.S. Most of his works explore the  Caribbean cultural experience. He is best known for his poetry; in vol�  umes such as In a Green Night (1962), The Gulf ( 1969), Another Life  (1973), The Star-Apple Kingdom (1979), The Fortunate Traveller (1981),  and The Bounty (1997), Walcott�s erudition is submerged in sweeping  rhythmic and sensuous sonorities. His epic poem Omeros (1990) is a  retelling of Homer�s Odyssey in a 20th-century Caribbean setting. Of his  approximately 30 plays, the best known are Dream on Monkey Mountain  (produced 1967), Ti-Jean and His Brothers (1958), and Pantomime  (1978). In 1992 he was awarded the Nobel Prize for Literature.</p><p>Wald, George (b. Nov. 18, 1906, New York, N.Y., U.S.�d. April 12,  1997, Cambridge, Mass.) U.S. biochemist.

His outstanding contributions were on the importance  of vitamin A, the mechanisms of the photochemical reactions in the rod cells  that enable night vision, and the identification of the colour-sensitive pig�  ments in the cone cells (see photoreception; retina). He shared the Nobel  Prize in 1967 with Haldan Keffer Hartline and Ragnar Arthur Granit. He  was a prominent opponent of the Vietnam War.</p><p>Waldeck \'val-,dek\ Former state, Germany. It is now a part of Hesse.  The capital was Arolsen. A county in the Middle Ages, Waldeck became  a principality in 1712 and part of Prussia in 1867.

In 1884 he  sponsored the law that legalized French trade unions. After returning to  his prosperous law practice, he became a senator in 1894. In the upheaval  over the Alfred Dreyfus affair, he was appointed premier (1899-1902) and  formed a coalition cabinet that persuaded the president to pardon Drey�  fus.</p><p>Waldenses \w6l-'den-,sez\ French Vaudois \vo-'dwa\ Italian  Valdesi \val-'da-ze\ Members of a Christian movement that originated  in 12th-century France. Devotees sought to follow the example of Jesus  and the Apostles by adopting lives of preaching and poverty. The move�  ment�s founder, Valdes, was condemned by the archbishop of Lyon for  continuing to preach without church permission. Although placed under  a ban in 1184 by Pope Lucius III (1181-85), Valdes remained orthodox  and hoped for eventual acceptance by the church. His followers, however,  gradually departed from Roman Catholicism by rejecting the clergy�s right  to administer the sacraments, the notion of purgatory, and the veneration  of saints. Rome responded by actively persecuting the Waldenses, and  their numbers diminished by the end of the 15th century. In the 16th cen�  tury they adopted some aspects of Protestant doctrine and the church  organization of Genevan Protestantism. Intermittently persecuted in later  centuries, they have remained a small movement within Christianity. They  survive today in Argentina, Uruguay, and the U.S.</p><p>Waldheim \'valt- l hlm\, Kurt (b.

Elected to suc�  ceed U Thant as UN secretary-  general, he served two terms, during  which he oversaw disaster relief in  Bangladesh, Nicaragua, and Guate�  mala and peacekeeping missions in  Cyprus, the Middle East, Angola,  and Guinea. Denied a third term, he  returned to Austria and ran for presi�  dent in 1986. His candidacy became  controversial when it was learned  that he had been a member of the  Nazi Party and had served in a Ger�  man army unit that had deported  most of the Jewish population of the  Greek town of Salonika to Nazi  death camps in 1943. Elected nonetheless, he was diplomatically isolated  throughout his term (1986-92).</p><p>Wales Welsh Cymru Vkom-reV Principality, constituting an integral part  of the United Kingdom. It occupies a peninsula on the western side of the  island of Great Britain. Area: 8,015 sq mi (20,758 sq km). Population  (2001): 2,903,085. Capital: Cardiff. The population is of Celtic, Anglo-  Saxon, and Anglo-Norman ancestry. Languages: English, Welsh. Reli�  gion: Methodism. Wales is almost entirely an upland area the core of  which is the Cambrian Mountains. The highest peak in England and  Wales, Mount Snowdon, is found in Snowdonia National Park. The Sev�  ern, Wye, and Dee are the longest rivers. Economic activities include  mining coal (though coal mining suffered a sharp decline in the late 20th  century), slate, and lead; importing and refining petroleum; and manu�  facturing consumer electronics. Tourism is an important industry. In pre�  historic times, tribal divisions of the British Celtic speakers who  dominated all of Britain south of the Firth of Forth and the Firth of Clyde  inhabited the region. The Romans ruled from the 1 st century ad until the  4th-5th century. Welsh Celts fought off incursions from the Anglo-  Saxons. A number of kingdoms arose there, but none was successful in  uniting the area. The Norman conquerors of England brought all of south�  ern Wales under their rule in 1093. English King Edward I conquered  northern Wales and made it a principality in 1284. Since 1301 the heir to  the English throne has carried the title Prince of Wales. Wales was incor�  porated with England in the reign of Henry VIII. It became a leading inter�  national coal-mining centre during the 19th century. The Plaid Cymru, or  Welsh Nationalist Party, was founded in 1925, but its influence did not  gather force until the 1960s, when Welsh nationalist aspirations rose. In  1997 a referendum approved the devolution of power to an elected assem�  bly, which first convened in 1999.</p><p>Wales, Prince of Title of the heir apparent to the British throne. In  1301 Edward I of England granted it to his son Edward after conquering  Wales and executing the last native Welsh prince (1283). Since that time  most of the eldest sons of English sovereigns have been given the title.  The title ceases to exist when a Prince of Wales becomes king, until a  monarch bestows it on a son.</p><p>Wat^sa \va-'len-s9,\ Polish \va-'we n -s9\, Lech (b. Sept. 29, 1943,  Popowo, near Wloclawek, Pol.) Polish labour leader and president of  Poland (1990-95). An electrician, he worked in the Lenin Shipyard at  Gdansk, Pol. (1967-76), but he was fired for his antigovernment activi�  ties. In 1980 he joined workers in a strike and soon became leader of the  Solidarity trade union. The union was banned in 1981, and he was detained  into 1982. In 1983 he was awarded the Nobel Prize for Peace; fearing  involuntary exile, he remained in Poland while his wife, Danuta, traveled  to Norway to accept the prize on his behalf. He continued to direct the  outlawed union until it received legal recognition in 1988. Solidarity won  an overwhelming victory in free elections in June 1989, and after Walesa  refused to form a coalition government with the communists, the Parlia�  ment was forced to accept a Solidarity-led government, though Walesa  himself refused to serve as premier. In 1990 he won Poland�s first direct  presidential election by a landslide, and he helped guide Poland into a  free-market economy. His confrontational style eroded his popularity, and  he was narrowly defeated in his bid for reelection in 1995.</p><p>Wall Allah \wa-Te-a-Ta\, Shah (b. 1702/03, Delhi�d. 1762, Delhi)  Indian Islamic theologian. He received a traditional Islamic education, and  after a pilgrimage to Mecca in 1732 he remained in the Hejaz to study  theology. Living in a time of disillusionment following the death of  Aurangzeb, he believed that Muslim polity could be restored only through  religious reform that would harmonize Islam with India�s changing social  and economic conditions. He was steadfastly monotheistic but otherwise  much more liberal than most Islamic theologians that had preceded him.  His best-known work is The Secrets of Belief. His synthesis of theology,  philosophy, and mysticism so reinvigorated Islam that it became preva�  lent among Islamic scholars in India until the 20th century.</p><p>Walker, Alice (Malsenior) (b. Feb. 9, 1944, Eatonton, Ga., U.S.)  U.S. writer. After attending Spelman College and Sarah Lawrence Col�  lege, Walker moved to Mississippi and became involved with the civil  rights movement. She also began teaching and publishing short stories  and essays. Her works are noted for their insightful treatment of African  American culture. Her third and most popular novel. The Color Purple  (1982, Pulitzer Prize; film, 1985), depicts a black woman�s struggle for  racial and sexual equality. Her later novels include The Temple of My  Familiar (1989) and Possessing the Secret of Joy (1992). She also wrote  essays, some collected in In Search of Our Mothers� Gardens (1983);  several books of poetry; short stories; and children�s books.</p><p>Walker, David (b. Sept. 28, 1785, Wilmington, N.C., U.S.�d. June  28, 1830, Boston, Mass.) U.S. abolitionist. The son of a slave father and  a free mother, he was educated and traveled widely before settling in  Boston, where he became an abolitionist lecturer and wrote for the anti�  slavery Freedom�s Journal. In his pamphlet Appeal to the Colored Citi�  zens of the World (1829), he called for armed revolt. He smuggled the  pamphlet into the South by hiding copies in clothing that he sold to sail�  ors from his used-clothes store in Boston. Warned to flee for his life to  Canada, he refused, and his body was found soon after; many believed  he was poisoned. His son, Edwin G. Walker, was elected to the Massa�  chusetts legislature in 1866.</p><p>Walker, James J(ohn) known as Jimmy Walker (b. June 19,  1881, New York, N.Y., U.S.�d. Nov. 18, 1946, New York City) U.S.  politician. He entered politics after graduating from New York Law  School, becoming a member of the Assembly (1909) and then of the State  Senate (1914). Backed by Gov. Alfred E. Smith and Tammany Hall, he was  elected mayor (1925-32). A popular figure known for his charm and wit  but particularly for his enthusiastic participation in the high life typical  of the era, he made improvements in sanitation, hospitals, and subways.  In 1931 the state legislature, investigating the city�s affairs, charged  Walker with corruption; he resigned in 1932.</p><p>Walker, Sarah Breedlove orig. Sarah Breedlove (b.

She was a widowed washerwoman with a daughter to support in 1905  when she developed a method for straightening curly hair. She founded the  Madame C.J. Walker Manufacturing Co. to sell her treatment, and her door-  to-door saleswomen became familiar figures in the black communities of  the U.S. and the Caribbean. In 1910 she moved her company to Indianapo�  lis, Ind. She augmented her earnings with shrewd real-estate investments,  and she donated two-thirds of her fortune to charitable and educational  institutions. Her daughter, A�Lelia Walker Kennedy, hosted salons where  artists and cultural figures mingled during the Harlem Renaissance.</p><p>Walker, William (b. May 8, 1824, Nashville, Tenn., U.S.�d. Sept.  12, 1860, Trujillo, Hond.) U.S. military adventurer. He moved to Cali�  fornia (1850), where his interest in colonizing Baja California developed  into a filibustering (insurrection) scheme. He landed at La Paz (1853) and  proclaimed Lower California and Sonora an independent republic, but  Mexican resistance forced him back to the U.S. In 1855 he sailed to Nica�  ragua, where he effectively established himself as leader. There officers  of Cornelius Vanderbilt�s Accessory Transit Co. promised him financial  assistance in a plot to take the company away from Vanderbilt. Walker  seized the company and turned it over to them, then made himself presi�  dent of Nicaragua (1856). In 1857 Vanderbilt induced five Central Ameri�  can republics to drive Walker out. In 1860 Walker attempted a filibuster  in Honduras, where he was captured and executed.</p><p>Walker Cup Trophy awarded to the winner of a golf competition  between amateur men�s teams from the U.S. and Britain.

Walk�  ing as a sport dates from the later 19th century. Walking races of 10 mi  and 3,500 m were added to the men�s Olympic program in 1908, but since  1956 the Olympic distances have been 20 km and 50 km. A women�s  10-km walk was introduced in 1992.</p><p>walking catfish Species ( Clarias batrachus) of Asian and African  catfish that can progress remarkable distances over dry land. It uses its  pectoral-fin spines as anchors to prevent jackknifing as its body muscu�  lature produces snakelike movements.

It has been intro�  duced into southern Florida, where it now poses a serious threat to native  fauna.</p><p>walking leaf See leaf insect</p><p>wall Any of various upright constructions used to divide or enclose a  room or building. In traditional masonry construction, bearing walls sup�  ported the weight of floors and roofs, but modern steel and reinforced-  concrete frames, as well as heavy timber and other skeletal structures,  require exterior walls only for shelter. Some urban buildings dispense with  walls on the ground floor, extending outdoor plazas under the building  and permitting easier access to elevators, escalators, and stairs. In masonry  construction, all types of floors and roofs except domes are most easily  supported on straight, parallel walls. Nonbearing walls, used when loads  are carried by girders, beams, or other members, can be either curtain  walls or infill of brick, block, or other material.

The street, in southern Manhattan, is narrow and  short and extends only about seven blocks from Broadway to the East  River. It was named for an earthen wall built by Dutch settlers in 1653 to  repel an expected English invasion. Even before the Civil War it was rec�  ognized as the nation�s financial capital, and it remains a worldwide sym�  bol of high finance. The Wall Street, or financial, district contains the New  York Stock Exchange, the American Stock Exchange, and the Federal  Reserve Bank of New York. The district is also the headquarters for many  investment banks, securities dealers, utilities and insurance companies, and  brokerage firms.</p><p>Wall Street Journal, The U.S. daily national newspaper, the most  influential American business-oriented paper and one of the most  respected dailies in the world. Founded in 1889 by Charles H. Dow,  founder of Dow Jones &amp; Co., it quickly won success. Beginning in the  Great Depression, The Wall Street Journal began to feature more articles,  reviews, and opinion on other subjects. Published in New York City and  with regional editions printed across the country, it has one of the high�  est daily circulations of any U.S. newspaper. It is also published in Asian,  European, and other special editions.</p><p>wallaby Vwa-lo-beX Any of about 25 species of medium-sized kanga�  roos, found chiefly in Australia. Brush wallabies (11 species) are built  like the big kangaroos but differ in dentition. Rock wallabies live among  rocks, usually near water. Nail-tailed wallabies, named for a homy growth  on the tail tip, rotate their forelimbs while hopping. The small hare wall�  abies resemble hares in movement and some habits. The small, stocky  scrub wallabies, hunted for meat and fur, have short hind limbs and pointy  noses. The similar short-tailed scrub wallaby occurs only on two offshore  islands of western Australia. Several wallaby species have been extermi�  nated, and several others are endangered. See photograph opposite.</p><p>Wallace, Alfred Russel (b. Jan. 8, 1823, Usk, Monmouthshire,  Wales�d. Nov. 7, 1913, Broadstone, Dorset, Eng.) British naturalist.  Though trained as a surveyor and architect, he became interested in botany  and traveled to the Amazon in 1848 to collect specimens. In 1854-62 he  toured the Malay Archipelago, augmenting his collection. His observa�  tions of the islands led to his developing a theory of the origin of species  through natural selection independently of, and simultaneously with,  Charles Darwin, though Darwin developed his own theory in much greater  detail, provided far more evidence for it, and was mainly responsible for  its acceptance. Unlike Darwin, Wallace insisted that the higher mental</p><p>capacities of humans could not have arisen by natural selection but that  some nonbiological agency must have been responsible. He hypothesized  a boundary (Wallace�s line) running between the islands of the Malay  Archipelago, between the Oriental and Australasian faunal regions, many  animals abundant on one side being absent on the other. In the realm of  public policy he supported socialism, pacifism, land nationalization, and  women�s suffrage. His works include Contributions to the Theory of Natu�  ral Selection (1870), Geographical Distribution of Animals (2 vol., 1876),  and Darwinism (1889).</p><p>Wallace, (William Roy) DeWitt and Lila Acheson Lila  Acheson Wallace orig.

May 8, 1984, Mount Kisco) U.S.  publishers and founders of Reader�s Digest magazine. DeWitt Wallace  began an index of favourite magazine articles while he was a college stu�  dent, and he developed the idea of a pocket-sized digest of popular articles  while recuperating from wounds suffered in World War I. Lila Acheson,  a minister�s daughter, worked in social services during the war. The two  were married in 1921. After various publishers rejected the digest idea,  they began publishing Reader's Digest themselves on a low budget and had  rapid success. DeWitt Wallace served as editor until 1965. They had no  heirs but supported numerous philanthropic causes; the Lila Wallace-  Reader�s Digest Fund has been a major benefactor of the arts and culture.</p><p>Wallace, (Richard Horatio) Edgar (b.

He held odd jobs, served in the army, and  was a reporter before producing his first success. The Four Just Men  (1905). With works such as Sanders of the River (1911), The Crimson  Circle (1922), The Flying Squad (1928), and The Terror (1930), he vir�  tually invented the modern �thriller�; the plots of his detective and sus�  pense stories are complex but clearly developed, and they are known for  their exciting climaxes. His output (including 175 books) was prodigious  and his rate of production so great as to be the subject of humour. His  literary reputation has suffered since his death.</p><p>Wallace, George C(orley) (b. Aug. 25, 1919, Clio, Ala., U.S.�d.  Sept. 13, 1998, Montgomery, Ala.) U.S. politician. He served in the Ala�  bama state legislature (1947-53). As a circuit court judge (1953-59), he  was known for his resistance to federal investigations of racial discrimi�  nation. Campaigning as a segregationist, he was elected governor in 1963  and kept his pledge �to stand in the schoolhouse door� to prevent enroll�  ment of African American students at the University of Alabama. He  yielded only in the face of the federalized National Guard. Further con�  frontations made him a nationwide symbol of Southern opposition to  racial integration. He formed the American Independent Party and was its  presidential candidate in 1968, winning 13% of the popular vote. He again  served as governor (1971-79). While campaigning for the 1972 Demo�  cratic presidential nomination, he was shot in an assassination attempt and  left partly paralyzed. In the 1980s he renounced his segregationist views,  and he won his last term as governor (1983-87) with support from Afri�  can American voters.</p><p>Bridled nail-tailed wallaby (Onychogalea fraenata).</p><p>� MITCH REARDON-NATIONAL AUDUBON SOCIETY COLLECTION/PHOTO RESEARCHERS</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2024 I Wallace &#x25BA; walleye</p><p>Wallace, Henry A(gard) (b.

Later he returned to law  practice, interrupted by two diplo�  matic postings. His literary reputa�  tion rests on three historical novels:</p><p>The Fair God (1873), on the Spanish  conquest of Mexico; The Prince of  India (1893), on the Byzantine  Empire; and, above all, the enor�  mously popular Ben-Hur (1880;  films, 1925, 1959), a romantic tale  set in the Roman Empire during the  time of Christ.</p><p>Wallace, Mike orig.

He served as a  naval communications officer during World War II and was subsequently  hired as a radio reporter in Chicago. He began to work on television in  the 1950s, hosting several television quiz shows. He joined CBS as a  reporter in 1963 and was coeditor of the long-running 60 Minutes from  its first program in 1968.

Son of a  small landowner, he began his attacks on English settlements and garri�  sons in 1297, after Edward I declared himself ruler of Scotland. His army  defeated a much larger English force at Stirling Bridge, captured Stirling  Castle, and then ravaged northern England, for which Wallace was  knighted and proclaimed guardian of the Scottish kingdom. In 1298  Edward I invaded Scotland and defeated Wallace at the Battle of Falkirk.  Disgraced, Wallace resigned his guardianship and was replaced by the  future Robert I but apparently continued to fight a guerrilla war. In 1305  he was arrested by the English and hanged, then disemboweled, beheaded,  and quartered.

When the Nazis sent troops to round up Jews in Hungary (1944),  Wallenberg asked to be sent to Budapest as a diplomat. There he rescued  thousands of Hungarian Jews by sheltering them in �protected houses�  under the Swedish flag or securing their passage out of Hungary through  bribes or counterfeit documents. Soon after Soviet troops occupied  Budapest (1945), he was arrested on suspicion of espionage. He was sent  to Moscow, where he allegedly died of a heart attack in prison in 1947.

His wife, Helen Kreis (1910-96), joined the  troupe in 1926 and later was balanced at the peak of the seven-person  pyramid, the most famous of the Wallendas� acts. The troupe traveled with  the U.S. Ringling Brothers and Bamum &amp; Bailey Circus (1928�46), then  performed as freelancers. Karl�s nephew Gunther (1927-96) trained on  the wire from age five; when a pyramid collapsed in 1962, Gunther was  the only member left standing and rescued three who were clinging to the  wire; two others were killed and one was paralyzed.

He remained loyal to Ferdinand when other Bohemian nobles revolted  (1618-23) and was made governor of Bohemia and allowed to acquire  vast holdings in confiscated estates. Created duke of Friedland (1625), he  commanded the imperial armies in the Thirty Years� War. After successes  in the war against Denmark (1625-29), he was awarded the principality  of Sagan (1627) and the duchy of Mecklenburg (1629). Under pressure  from the German princes, Ferdinand was forced to dismiss Wallenstein.  Recalled to imperial command in 1631, he drove the Swedish army from  Bavaria and Franconia but was defeated at the Battle of Liitzen (1632).

He later  wrote poetic tributes to both Oliver Cromwell (1655) and Charles II (1660).  Rejecting the dense intellectual verse of Metaphysical poetry, he adopted  generalizing statement, easy associative development, and urbane social  comment. With his emphasis on definitive phrasing through inversion and  balance, he prepared the way for the emergence of the heroic couplet. By  the end of the 17th century the heroic couplet was the dominant form of  English poetry. Waller�s lyrics include the well-known �Go, lovely Rose!�</p><p>Waller, Fats orig.

His literary output was  extremely varied. He became famous  for his medieval horror tale The  Castle of Otranto (1765), the first  Gothic novel in English. He is espe�  cially remembered for his private  correspondence of more than 3,000  letters, most addressed to Horace  Mann, a British diplomat.

His acclaimed art collection, sold to  Russia in 1779, became part of the Hermitage Museum collection.</p><p>Walpurgis Night Night before May 1. The name comes from the 8th-  century St. Walburga (or Walpurgis), an English missionary who ran an  important early convent in Germany, May 1 being one of her feast days.  In Sweden it is celebrated with bonfires as the beginning of spring. In  Germany, as Walpurgisnacht, it was the night witches were supposed to  meet in the Harz Mountains (see Brocken), though the association of  witches with St. Walburga is only coincidental.

An advocate of cooperatives as an alternative to revolution, he  ran a bank for producers� cooperatives with Leon Say (grandson of Jean-  Baptiste Say) from 1865 to 1868. At the Academy of Lausanne, Switz.  (1870-92), he began the school of economics later known (under Vilfredo  Pareto) as the Lausanne school. Walras�s Elements of Pure Economics  (1874-77) was one of the first comprehensive mathematical analyses of  general economic equilibrium. Assuming an environment of free compe�  tition, he constructed a mathematical model in which productive factors,  products, and prices automatically adjust in equilibrium. He thus tied  together the theories of production, exchange, money, and capital.</p><p>walrus Only living species ( Odobenus rosmarus) of the pinniped family  Odobenidae. Larger than the related  seals, walrus males grow up to 12 ft  (3.7 m) long and weigh up to 2,800  lbs (1,270 kg). Both sexes have long,  downward-pointing tusks that may  grow to 3 ft (1 m) long and weigh 12  lbs (5.4 kg) each. They have no exter�  nal ears. The grayish skin is deeply  folded over the shoulders. They live  on ice floes, in groups of up to 100, on  relatively shallow water in arctic seas  of Eurasia and North America. They  may dive to great depths in search of  food, mostly shellfish. On land and  ice, they move on all four limbs. They  generally follow the ice line south in  winter and north in summer. Tradi�  tionally important to native humans  as sources of food and clothing, they  have also been hunted commercially  for centuries, which has resulted in serious depletion of their numbers.  Commercial hunting is now generally banned.</p><p>Walsh, Raoul (b. March 11, 1887, New York, N.Y., U.S.�d. Dec. 31,  1980, Simi Valley, near Los Angeles, Calif.) U.S. film director. Walsh  began acting for the stage in 1910 and on film in 1912, the same year that  he began directing. He was an assistant to D.W. Griffith and appeared in  The Birth of a Nation (1915). In his 50-year career, he directed over 200  films, usually characterized by their simplicity and quick action. His White  Heat (1949) is a classic study of a pathological criminal, and The Naked  and the Dead (1958) is an effective translation of Norman Mailer�s novel  into film. His other films include What Price Glory? (1926), The Roar�  ing Twenties (1939), They Drive by Night (1940), They Died with Their  Boots On (1941), High Sierra (1941), and A Distant Trumpet (1964).</p><p>Walsingham, Sir Francis (b. c. 1532, probably Footscray, Kent,  Eng.�d. April 6, 1590, London) English statesman and adviser to Queen  Elizabeth I (1573-90). A member of Parliament from 1563, he became  ambassador to the French court (1570-73) and established friendly rela�  tions between France and England. He was admitted to the Privy Council  in 1573 and became secretary of state to Elizabeth I. Although not allowed  to pursue an independent policy, he faithfully executed Elizabeth�s foreign  policy. He proved invaluable in uncovering conspiracies by Catholics  against Elizabeth�s life, including the plots by Francis Throckmorton  (1583) and Anthony Babington (1586) to free Mary, Queen of Scots.</p><p>Walter, Bruno orig. Bruno Walter Schlesinger (b. Sept. 15,  1876, Berlin, Ger.�d. Feb. 17, 1962, Beverly Hills, Calif., U.S.) German-  bom U.S. conductor. An associate of Gustav Mahler, he was long a faith�  ful proponent and interpreter of Mahler�s music, giving the world</p><p>premieres of Das Lied von der Erde (1911) and the Symphony No. 9  (1912). He held positions in Munich (1913-22) and at Co vent Garden  (1924-31), but thereafter he served more often as a guest conductor than  a music director. After moving to the U.S. in 1939, he often conducted  the New York Philharmonic (recording as the Columbia or CBS Sym�  phony), the Metropolitan Opera, the Philadelphia Orchestra, and the Los  Angeles Philharmonic, and he was admired for the warmth of his inter�  pretations, primarily of the Viennese school.</p><p>Walter, John (b. 1739, probably in London, Eng.�d. Nov. 16, 1812,  Teddington, Middlesex) English newspaper publisher. Initially a coal  dealer and marine-insurance underwriter, Walter acquired the patent for  a printing system in 1783 and in 1785 in London began to publish the  Daily Universal Register. He renamed it The Times in 1788. Though nei�  ther outstanding nor honest as a journalist, he turned from scandal to more  serious topics and organized (while in prison for libeling members of the  royal family) a news service from the European continent, thereby launch�  ing The Times toward its later preeminence in foreign news reporting.  Walter�s family owned The Times for almost 125 years.</p><p>Walters, Barbara (b. Sept. 25, 1931, Boston, Mass., U.S.) U.S. tele�  vision journalist. After brief employment in an advertising agency, she  became assistant to the publicity director for New York City�s NBC-  affiliated television station. She worked in television as a writer-producer  (1952-58), interviewer (1964-74), and cohost (1974-76) of NBC�s Today  show, for which she won an Emmy Award in 1975. In 1976-78, for an  unprecedented $ 1 million a year, she was coanchor of the ABC Evening  News, the first woman to anchor a network newscast in the U.S. From  1976 she hosted the series of Barbara Walters Specials, interviewing  celebrities and world leaders Her disarmingly direct questioning drew  many subjects into frequently interesting and occasionally provocative  moments of self-revelation. In 1982 and 1983 she received Emmy Awards  for best interviewer. From 1984 she also cohosted ABC�s 20/20 news  magazine program.</p><p>Walther von der Vogelweide Vval-tor-fon-der-'fo-gol-.vI-doX (b. c.  1170�d. c. 1230, Wurzburg?) Greatest German lyric poet of the Middle  Ages. Of knightly birth, Walther was educated at a monastery school and  served masters in several courts. His poetry goes far beyond the artificial  conventions followed by other minnesingers by introducing an element of  realism. He emphasizes the virtues of the balanced life, in both the social  and the personal spheres. More than half of his approximately 200 extant  poems are political, moral, or religious; the rest are love poems, among  them the popular �Unter der Linden.�</p><p>Walton, Izaak (b. Aug. 9, 1593, Stafford, Staffordshire, Eng.�d. Dec.  15, 1683, Winchester, Hampshire) English biographer and author. A pros�  perous ironmonger with only a few years of schooling, he read widely,  developed scholarly tastes, and associated with men of learning. A friend  and fishing companion of John Donne, he contributed �An Elegie� to the  posthumous publication of Donne�s poetry (1633) and wrote biographies  of Donne (1640), George Herbert (1670), and others. His classic The Com-  pleat Angler (1653), a pastoral discourse on the joys and stratagems of  fishing, is one of the most frequently reprinted works in English litera�  ture, most often in a revision (1676) with additions by Charles Cotton</p><p>(1630-87).</p><p>Walton, Sam(uel Moore) (b. March 29, 1918, Kingfisher, Okla.,  U.S.�d. April 5, 1992, Little Rock, Ark.) U.S. retail magnate, founder  of Wal-Mart Stores, Inc. He attended the University of Missouri and then  trained with the J.C. Penney Co. In 1945 he started a chain of variety stores  in Arkansas, and in 1962 he opened his first Wal-Mart store in Rogers,  Ark., offering a wide selection of discount merchandise. Whereas other  discount-store chains were usually situated in or near large cities, Walton  based his stores in small towns where there was little competition from  established chains. Using this strategy his company expanded to 800  stores by 1985. In 1983 he opened the first Sam�s Wholesale Club. Wal�  ton stepped down as chief executive officer of Wal-Mart Stores in 1988  but remained chairman until his death, by which time there were over  1,700 stores and Walton�s family was the wealthiest in the U.S. In the  1990s Wal-Mart became controversial for depleting downtown districts  of their commercial life by siting stores nearby. By the end of the 20th  century it had become the world�s largest retailer.</p><p>Walton, Sir William (Turner) (b. March 29, 1902, Oldham, Lan�  cashire, Eng.�d.

He established his reputation at age 19 by setting to jazzy music  the whimsical poetry of Edith Sitwell (see Sitwell family); Fagade (1923)  premiered with the poet reading her poetry through a megaphone. Wal�  ton�s later works include Belshazzar�s Feast (1931), two symphonies  (1935, 1960), and concertos for viola, violin, and cello (1929, 1939,  1956). His scores for Laurence Olivier�s films of Henry V (1944), Hamlet  (1947), and Richard III (1955) became well known; he also wrote coro�  nation marches for George VI and Elizabeth II.</p><p>waltz Ballroom turning dance evolved from the landler in the 18th cen�  tury. It is characterized by a step, slide, and step in 3/4 time. It was highly  popular in the 19th and early 20th century. Variations include the rapid,  whirling Viennese waltz and the slower, dipping Boston waltz, modified  by Vernon and Irene Castle as the hesitation waltz. Many 19th-century  composers wrote waltz music, most notably Franz Peter Schubert, Frederic  Chopin, Johannes Brahms, and Johann Strauss.</p><p>Walvis Bay Town (pop., 2001 prelim.: 40,849), west-central Namibia,  on the Atlantic Ocean. A mid-19th-century rush to exploit guano depos�  its on nearby islands was followed by British annexation of the bay and  the adjacent land in 1878. It was incorporated into Britain�s Cape Colony  in 1884. In 1910 it was included in the newly united South Africa. Admin�  istered as part of South West Africa (1922-77), it was then governed  directly by South Africa, which retained the enclave after Namibia  reached independence in 1990. The two countries administered the  enclave jointly from 1992 to 1994; then South Africa transferred it to  Namibia. Its harbour serves as Namibia�s chief port.</p><p>wampum Tubular shell beads assembled into strings or woven into  belts or embroidered ornaments. The Algonquian word (short for wam-  pumpeag ) translates as �string of white (shell beads).� Before contact with  white settlers, Indians used wampum primarily ceremonially or in gif  exchanges. In the early 17th century it came to be used as money in trade  with whites, because of a shortage of European currency.</p><p>Wanaka Vwa-no-koV Lake Lake, west-central South Island, New  Zealand. It covers an area of 75 sq mi (193 sq km) and is some 1,000 ft  (300 m) deep. Fed by the Makarora and Matukituki rivers, the lake is the  source of the Clutha River. Its outlet is harnessed for hydroelectric power.</p><p>Wang Anshi or Wang An-shih Vwaq-'an-'shnA (b. 1021, Linchuan,  Jiangsu province, China�d. 1086, Jiangning, Jiangsu) Chinese poet and  government reformer of the Song dynasty. His �New Policies� of 1069-76  sparked academic controversy that continued for centuries. He created a  fund for agricultural loans to farmers to spare them the exorbitant  demands of moneylenders; he also replaced corvee labour with a hired-  service system financed by a graduated tax levied on all families. He  enabled officials to purchase supplies at the cheapest price in the most  convenient market. He established a village militia system (see baojia),  reorganized the Hanlin Academy, and restructured the civil service exami�  nations. Wang�s reforms were unpopular, and he was forced to resign in  1074. He returned to government in 1075, but with less political power.  After the emperor�s death an antireform clique came to power and dis�  mantled Wang�s reforms by the time of his death shortly afterward. See  also Fan Zhongyen.</p><p>Wang Chong or Wang Ch'ung \'waq-'chuq\ (b. ad 27, Kuiji,  China�d. 100?, Kuiji) Chinese philosopher of the Han dynasty. A ratio�  nalistic naturalist, he paved the way for the critical spirit of the next  philosophical period and prepared China for the advent of Neo-Daoism.  He opposed the superstitious element of Confucianism, declaring that natu�  ral events occur spontaneously and are not influenced by the actions of  humans, who have no exceptional position in the universe. He also  insisted that theories be supported by concrete evidence and experimen�  tal proof. Though never greatly popular in China, he attracted new inter�  est in the 20th century for his foreshadowing of rationalism and the  SCIENTIFIC METHOD.</p><p>Wang Hui (b. 1632, Jiangsu province, China�d. 1717) Chinese artist  who was the paramount member of the group of Chinese painters known  as the Four Wangs (including Wang Shimin, Wang Jian, and Wang  Yuanqi). Wang Hui, much like the other Wangs, primarily painted land�  scapes. In his best works he built up an intense web of rhythmic brush-  work, while at the same time maintaining a composition�s sense of unity  and clarity. His fame reached the court in Beijing, and in 1691-98 he was  commissioned to supervise the production of a series of hand scrolls  commemorating the Kangxi emperor�s tour of the South.</p><p>Wang Jingwei or Wang Ching-wei Vwag-'jiq-'waN (b. May 4,</p><p>1883, Sanshui, Guangdong province, China�d. Nov. 10, 1944, Nagoya,  Japan) Chinese leader, head of the regime established by the Japanese in  1940 to govern their conquests in China. A leading polemicist for Sun  Yat-sen�s revolutionary party, in 1910 he tried to assassinate the imperial  regent and was caught; his courage in the face of execution resulted in  his sentence being reduced. He was released the following year, after the  republican revolution. In the 1920s he served as a major official in the  Nationalist Party. After Sun�s death, he chaired the party while Chiang  Kai-shek led the Northern Expedition against China�s warlords. Chiang and  Wang vied for party control; in a compromise in 1932, Wang became  president and Chiang headed the military. After war erupted with Japan,  Wang flew to Hanoi, Viet., and issued a statement calling on the Chinese  to work out a peaceful settlement. In 1940, in cooperation with the Japa�  nese, he became head of a regime that governed the Japanese-occupied  areas centred on Nanjing. Though Wang had hoped to be granted virtual  autonomy, the Japanese continued to exercise military and economic  dominance. He died while undergoing medical treatment in Japan.</p><p>Wang Mang \'waq-'maq\ (b. 45 bc, China�d. Oct. 6, ad 23, Chang�an)  Founder of the short-lived Xin dynasty (ad 9-25), an interlude between  the two halves of the Han dynasty in China. Wang�s family was well con�  nected to the Han imperial family, and in 8 bc Wang was appointed regent,  only to lose the position when the emperor died. When the new emperor  died in 1 bc, Wang was reappointed regent and married his daughter to  the subsequent emperor, Ping, who died in ad 6. Wang picked the young�  est of more than 50 eligible heirs to follow Ping and was named acting  emperor. In ad 9 he ascended the throne and proclaimed the Xin dynasty.  His dynasty might have endured had the Huang He (Yellow River) not  changed course twice before ad 11, causing massive devastation and atten�  dant famines, epidemics, and social unrest. Peasants banded together in  ever larger units. In ad 23 rebel forces set the capital, Chang�an (modem  Xi�an), on fire, forced their way into the palace, and killed him.</p><p>Wang Xiaotong (fl. early 7th century) Chinese mathematician who  made important advances in the solution of problems involving cubic  equations. In 626 he took part in the revision of the Wuying calendar  (618), which had erroneously predicted eclipses in 620. About 630 he fin�  ished his Jigu suanjing (�Continuation of Ancient Mathematics�). All 20  problems in this book, except for the first one dealing with astronomy,  involve cubic or biquadratic equations. Thirteen of the problems involve  solving for the volume or the dimensions of a polyhedron. In solving some  of these problems, Wang first used the formula for the volume of a dike  of varying cross section. Other problems involve right-angled triangles.</p><p>Wang Yangming or Wang Yang-ming Vwaq-'yaq-'miqV (b. 1472,  Yuyao, Zhejiang province, China�d. 1529, Nanen, Jiangxi) Chinese  scholar and official whose idealistic interpretation of Neo-Confucianism  influenced philosophical thinking in East Asia for centuries. The son of a  high government official, he was both a secretary to the Ministry of War  and a lecturer on Confucianism by 1505. The next year, he was banished  to a post in remote Guizhou, where hardship and solitude led him to focus  on philosophy. He concluded that investigation of the principles of things  should occur within the mind rather than through actual objects and that  knowledge and action are codependent. Named governor of southern  Jiangxi in 1516, he suppressed several rebellions and implemented gov�  ernmental, social, and educational reform. By the time he was appointed  war minister (1521), his followers numbered in the hundreds. His phi�  losophy spread across China for 150 years and greatly influenced Japa�  nese thought during that time. From 1584 he was offered sacrifice in the  Confucian temple under the title Wencheng (�Completion of Culture�).</p></section><section><p>Wankel Vvaq-kalV Felix (b. Aug. 13, 1902, Lahr, Ger.�d. Oct. 9,  1988, Lindau, W.Ger.) German engineer and inventor. In 1954 he com�  pleted the design of his distinctive engine, with an orbiting rotor in the  shape of a curved equilateral triangle, which does the work done by the  pistons in traditional reciprocating internal-combustion engines. Its  advantages include light weight, few moving parts, compactness, low ini�  tial cost, fewer repairs, and relatively smooth performance.

Instead, the newly planned final solution would entail  rounding up all Jews throughout Europe, transporting them eastward, and  organizing them into labour gangs. The final protocol of the Wannsee  Conference never explicitly mentioned extermination, but, within a few  months after the meeting, the first gas chambers were installed at Aus�  chwitz and Treblinka.

On the national level,  some wars are fought internally between rival political factions (civil  war); others are fought against an external enemy. Wars have been fought  in the name of religion, in self-defense, to acquire territory or resources,  and to further the political aims of the aggressor state�s leadership.</p><p>War Communism (1918-21) Soviet economic policy applied by the  Bolsheviks during the Russian Civil War. Its chief features were the expro�  priation of private business and the nationalization of industry, as well as  the forced requisition of surplus grain and other food products from the  peasantry. These measures caused a rapid decline in agricultural produc�  tion, labour productivity, and industrial output. Real wages declined by  two-thirds, and uncontrolled inflation made paper currency worthless. By  1921 public discontent resulted in strikes and protests, culminating in the  Kronshtadt Rebellion. In response, the Bolsheviks adopted the less-radical  New Economic Policy.</p><p>war crime Any violation of the laws of war, as laid down by interna�  tional customary law and certain international treaties. At the end of World  War II, the part of the London Agreement signed by the U.S., Britain, the  Soviet Union, and France established three categories of war crime: con�  ventional war crimes (including murder, ill treatment, or deportation of  the civilian population of occupied territories), crimes against peace, and  crimes against humanity (political, racial, or religious persecution against  any civilian population). The charter also provided for an international  military tribunal to try major Axis war criminals. It further stated that a  defendant�s position as head of state would not free him from account�  ability, nor would having acted on orders or out of military necessity.  German and Japanese war criminals were tried before Allied tribunals in  NUrnberg and Tokyo in 1945-46 and 1946-48, respectively, and in the  1990s tribunals were created for the prosecution of war crimes commit�  ted in Rwanda and the territory of the former Yugoslavia.

The term was applied by opponents to newly elected  Southern and Western congressmen who strongly promoted U.S. expan�  sion into the Northwest and Canada and vigorously protested British aid  to Indians. The anti-British fervour of the War Hawks, who included  Henry Clay and John C. Calhoun, helped cause the War of 1812.</p><p>War of 1812 U.S.-British conflict arising from U.S. grievances over  oppressive British maritime practices in the Napoleonic Wars. To enforce  its blockade of French ports, the British boarded U.S. and other neutral</p><p>ships to check cargo they suspected was being sent to France and to  impress seamen alleged to be British navy deserters. The U.S. reacted by  passing legislation such as the Embargo Act (1807); Congress�s War  Hawks called for expulsion of the British from Canada to ensure frontier  security. When the U.S. demanded an end to the interference, Britain  refused, and the U.S. declared war on June 18, 1812. Despite early U.S.  naval victories, notably the duel between the Constitution and the Guer-  riere , Britain maintained its blockade of eastern U.S. ports. A British force  burned public buildings in Washington, D.C., including the White House,  in retaliation for similar U.S. acts in York (Toronto), Can. The war became  increasingly unpopular, especially in New England, where a separatist  movement originated at the Hartford Convention. On Dec. 24, 1814, both  sides signed the Treaty of Ghent, which essentially restored territories  captured by each side. Before news of the treaty reached the U.S., its vic�  tory in the Battle of New Orleans led it to later proclaim the war a U.S.  victory.

The  son of a local official in Flanders, while working as a servant in Ireland  in 1491, he was misidentified as royalty while dressed in his master�s rich  silks and was soon persuaded to impersonate Richard, duke of York, who  was presumed to have been murdered with his brother in the Tower of  London in 1483. Encouraged by several monarchs and other Yorkist  enemies in both England and Europe, he gathered forces and supporters  on the continent for an invasion.

The warble flies Hypoderma lineatum and H. bovis, also called cattle  grubs or heel flies, are large, heavy, and beelike. They deposit their eggs  on the legs of cattle. The larvae penetrate the skin, migrate through the  body, and produce a lump, or warble, on the animal�s back. Mature grubs  emerge and drop to the ground to pupate. Warbles contain breathing holes,  which reduce the hide�s commercial value.

In the 1920s, after earning doctorates in  chemistry and medicine, he investigated the process by which oxygen is  consumed in the cells of living organisms, introducing the technique of  measuring changes in gas pressure for studying the rates at which slices  of living tissue take up oxygen. His search for the cell components  involved in oxygen consumption led to identification of the role of the  cytochromes. He was awarded a 1931 Nobel Prize for his research. He  was the first to observe that the growth of cancer cells requires much less  oxygen than that of normal cells.</p><p>Warburg family orig.

Feb. 22, 1987, New York, N.Y.) U.S. artist and  filmmaker. The son of Czech immigrants, Warhol graduated from the  Carnegie Institute of Technology, Pittsburgh, in 1949. He then went to  New York City, where he worked as a commercial illustrator. Warhol  began painting in the late 1950s and received sudden notoriety in 1962,  when he exhibited paintings of Campbell�s soup cans, Coca-Cola bottles,  and wooden replicas of Brillo soap-pad boxes. By 1963 he was mass-  producing these purposely banal images of consumer goods by means of  photographic silk screen prints; he then began printing endless variations  of portraits of celebrities in garish colours. The silk screen technique was  ideally suited to Warhol, for the repeated image was reduced to a dehu�  manized cultural icon that reflected both the supposed emptiness of  American material culture and the artist�s emotional distance from the  practice of his art. Warhol�s work placed him in the forefront of the  emerging Pop art movement in the United States. As the 1960s progressed,  Warhol devoted more of his energy to filmmaking. His �underground�  films are known for their inventive eroticism, plotless boredom, and inor�  dinate length (up to 25 hours). Throughout the 1970s and until his death  he continued to produce prints depicting political and Hollywood celeb�  rities, and he involved himself in a wide range of advertising illustrations  and other commercial art projects. He was one of the most famous and  important American cultural figures of the late 20th century, and the  effects of his conceptions of art and celebrity continue to be felt.</p><p>warlord In China, an independent military commander in the early 20th  century.

Beginning in Pennsylvania as  movie distributors and theatre owners in 1903, the four Warner brothers  started producing their own films in 1913 and moved to Hollywood in  1917. They founded Warner Brothers Pictures Inc. in 1923, with Harry  Warner (b. 1881�d. 1958) as president in New York, Albert Warner (b.  1884�d. 1967) as treasurer, and Sam Warner (b. 1888�d. 1927) and Jack  Warner (b. 1892�d. 1978) as studio managers in Hollywood. In the mid  1920s they helped develop the important Vitaphone sound process. With  the release of The Jazz Singer (1927), the first feature film with synchro�  nized music and dialogue, the studio�s success was assured. Warner Broth�  ers went on to produce gangster films starring James Cagney and Edward  G. Robinson, adventure movies with Errol Flynn, and mystery dramas with  FIumphrey Bogart.

In 1953 Pres.  Dwight D. Eisenhower appointed Warren chief justice of the Supreme Court  of the United States, a post he held until 1969. This was a period of sweeping  changes in U.S. constitutional law. Under his leadership the court proved to  be strongly liberal. Among Warren�s notable opinions are those in Brown  v. Board of Education (1954), which held that segration in public education  was unconstitutional; Reynolds v. Sims (1964), which declared the �one  man, one vote� principle requiring state legislative reapportionment  (1964); and Miranda v. Arizona (1966), which held that police must inform  an arrestee of his right to remain silent and to have counsel present  (appointed for him if he is indigent) and that a confession obtained in defi�  ance of these requirements is inadmissible in court.

Later he taught  at several colleges and universities and helped found and edit The South�  ern Review (1935-42), possibly the most influential American literary  magazine of the time. His writings often treat moral dilemmas in a South  beset by the erosion of its traditional rural values. His best-known novel  is All the King�s Men (1946, Pulitzer Prize; film, 1949). The short-story  volume The Circus in the Attic (1948) contains the notable �Blackberry  Winter.� He won Pulitzer prizes for poetry in 1958 and 1979 and became  the first U.S. poet laureate in 1986.</p><p>Warren Commission officially President's Commission on  the Assassination of President John F.

Founded c. 1300, it flourished as a trade centre, came under  Polish control in 1526, and became the capital in 1596. During the late  18th century it expanded rapidly, but it was destroyed in 1794 by the Rus�  sians. In 1807 it was made the capital of the Duchy of Warsaw by Napo�  leon. Taken by the Russians in 1813, it was the centre of Polish  insurrections in 1830-31 and 1860. It was occupied by the Germans in  World War I and again in World War II, when its large Jewish popula�  tion revolted in the Warsaw Ghetto Uprising (1943). The Warsaw Upris�  ing in 1944 was unsuccessful, and the Germans virtually destroyed the  city.

Among its historic buildings are a 14th-century Gothic  cathedral and a medieval castle.</p><p>Warsaw, Duchy of or Grand Duchy of Warsaw Independent  Polish state (1807-15), created by Napoleon. Established by the Treaties  of Tilsit in 1807 after the Poles had helped Napoleon defeat Prussia, it  consisted originally of the major portion of the central Polish provinces  that Prussia had taken in the 1790s. For Napoleon�s second war against  Russia (1812), the Duchy of Warsaw supplied nearly 98,000 men, but  Napoleon�s defeat in Russia also sealed the fortunes of the duchy. In 1813  the Russians assumed control of it. Later the Congress of Vienna divided  it into three parts: the Grand Duchy of Poznan; the free Republic of  Krakow; and the Congress Kingdom of Poland, which was joined to Rus�  sia by making the Russian emperor its king.</p><p>Warsaw Ghetto Uprising (April 19-May 16, 1943) Revolt by Pol�  ish Jews under Nazi occupation against deportation to the Treblinka exter�  mination camp. By July 1942 the Nazis had herded 500,000 Jews from  surrounding areas into the ghetto in Warsaw. Though starvation killed  thousands each month, the Nazis began transferring more than 5,000 Jews  a day to rural �labour camps.� When word reached the ghetto in early  1943 that the destination was actually the gas chambers at Treblinka, the  newly formed Jewish Fighting Organization (ZOB) attacked the Nazis,  killing 50 in four days of street fighting and causing the deportations to  halt. On April 19 Heinrich Himmler sent 2,000 SS men and army troops to  clear the ghetto of its remaining Jews. For four weeks the ZOB and guer�  rillas fought with pistols and homemade bombs, destroying tanks and  killing several hundred Nazis, until their ammunition ran out. Not until  May 8 did the Nazis manage to take the ZOB headquarters bunker. Many  of the surviving ZOB fighters took their own lives to avoid being cap�  tured. The battle raged until May 16, when the SS chief declared �The  Warsaw Ghetto is no more.� During the 28 days of the uprising, more  than 40,000 Jews were either killed or deported.</p><p>Warsaw Pact or Warsaw Treaty Organization Military alli�  ance of the Soviet Union, Albania (until 1968), Bulgaria, Czechoslova�  kia, East Germany, Hungary, Poland, and Romania, formed in 1955 in  response to West Germany�s entry into NATO. Its terms included a uni�  fied military command and the stationing of Soviet troops in the other  member states. Warsaw Pact troops were called into action to suppress  uprisings in Poland (1956), Hungary (1956), and Czechoslovakia (1968).  The alliance was dissolved in 1991 after the collapse of the Soviet bloc,  and Soviet troops departed. Several Warsaw Pact members later joined  NATO.</p><p>Warsaw Uprising (August-October 1944) Insurrection in Warsaw in  World War II that failed to prevent the pro-Soviet Polish administration  from gaining control of Poland. In July 1944, as Soviet troops approached  Warsaw, the Polish underground was encouraged to stage an uprising  against the Germans. Though wary of Soviet promises of self-  government, the Polish home army of 50,000 troops attacked the weak�  ened German force and gained control of most of Warsaw in four days.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>wart &#x25BA; Washington i 2031</p><p>German reinforcements then bombarded the city with air and artillery  attacks for 63 days.

During the fighting, some 300,000 Poles died. By allowing the  Polish home army to be eliminated, the Soviets diminished potential resis�  tance to their establishing political domination of Poland in 1945.</p><p>wart or verruca Wo-'rii-koX Well-defined growth on the skin, usually  caused by a papillomavirus, which triggers overproduction of epidermal  cells. This may lead to a single long-standing wart, profuse local spread  (especially in moist areas), or warts in various parts of the body. The most  common type is a round bump with a dry, rough surface. Warts are usu�  ally painless except in pressure areas, such as the sole of the foot (plan�  tar wart). Genital warts are merely a nuisance unless they become large  or numerous enough to interfere with urination, defecation, or childbirth,  but some viral strains are associated with cervical cancer. Warts are con�  sidered contagious. They may be removed by applying acids, cryother�  apy, electrocautery, or surgery; they sometimes disappear spontaneously.</p><p>Warta \'var-ta\ River River, west-central Poland.

Known for  its historic castle, it grew up at a crossing place on the River Avon and  was fortified c. 915. By 1086 it was a royal borough, and William I ordered  the castle to be enlarged. The present-day castle dates mainly from the  14th and 15th centuries. With its virtually intact structure and its fine col�  lections of paintings and armour, the castle has become a major tourist  attraction. The town, which grew around the castle, is a market centre and  has light industry.</p><p>Warwick Vwar-ik\, Earl of orig. Richard Neville (b. Nov. 22,  1428 �d. April 14, 1471, Barnet, Hertfordshire, Eng.) English nobleman  influential in the Wars of the Roses. Son of the earl of Salisbury, he became  through marriage (1449) the earl of Warwick and acquired vast estates.  With his father, he helped the Yorkists win the Battle of St. Albans (1455).  Appointed captain of Calais, in 1460 he crossed to England to defeat and  capture Henry VI at Northampton. In 1461 he was routed by the Lancas�  trians, but he recovered to march on London with York�s son Edward,  soon crowned Edward IV. Warwick was the virtual ruler during Edward�s  early reign (1461-64), but tensions between the two mounted, and in 1469  Warwick engineered a revolt in northern England that forced Edward to  flee to Flanders in 1470. Warwick joined the Lancastrians and restored  Henry VI to the throne, earning his later nickname �the Kingmaker.� He  was killed by Edward�s forces at the Battle of Barnet.</p><p>Warwickshire \'war-ik-,shir\ Administrative (pop., 2001: 505,885)  and historic county, central England. As an administrative and geographic  unit, the county dates from the 10th century, with the historic county town  of Warwick lying roughly at its centre. In Saxon times Warwickshire</p><p>formed a border zone between the kingdoms of Wessex and Mercia. Dur�  ing the Middle Ages two major centres grew up in the county, at Warwick  and Kenilworth. Historical structures surviving in the area include Nor�  man and early English churches, along with buildings at Stratford-upon-  Avon associated with William Shakespeare. The Battle of Edgehill (1642),  the first serious clash of the English Civil Wars, was fought in Warwick�  shire near the Oxfordshire border.

It covers an area of 68,139 sq mi (176,479 sq km); its capital is  Olympia. The state contains the Cascade Range, which includes Mount  Rainier and Mount Saint Helens, and the Olympic Mountains. The Strait of  Juan de Fuca and Puget Sound extend inland into the state from the Pacific  Ocean. Cape Alva, the most westerly point of the coterminous U.S., is in  Washington, as is the Columbia River. The area was inhabited by Pacific  Coast Indians, including the Chinook and Nez Perce, when the region was  visited by Spanish, Russian, British, and French explorers (1543-1792).  Claimed by the Spanish and British, it was crossed by the Lewis and Clark  Expedition in 1805. Spain surrendered to the U.S. its territories north of  California in 1819. Until the 1840s, international agreement permitted  citizens of both the U.S. and Britain to settle in what was known as Oregon  Country. An 1846 treaty with Great Britain set the present Washington-  Canada boundary; the Oregon Country was added to the U.S. and renamed  the Territory of Oregon in 1848. Washington received territorial status in  1853 and was reduced to its present size in 1863. It was admitted to the  Union as the 42nd state in 1889. In the late 1890s it was the main stag�  ing point for gold miners going to the Alaskan and Yukon strikes. The  greatest stimulus to its 20th-century progress came with the development  of hydroelectric power and the work on the Bonneville and Grand Cou�  lee dams. Its important manufactures include aircraft building and ship�  building. Expanding trade with Pacific Rim countries, high technology,  and tourism add to the economy.</p><p>Washington, Booker T(aliaferro) (b. April 5, 1856, Franklin  county, Va., U.S.�d. Nov. 14, 1915, Tuskegee, Ala.) U.S. educator and  reformer. Born into slavery, he moved with his family to West Virginia  after emancipation. He worked from age nine, then attended (1872-75)  and joined the staff of the Hampton (Va.) Normal and Agricultural Insti�  tute. In 1881 he was selected to head the Tuskegee Normal and Industrial  Institute, a new teacher-training school for African Americans, and he  successfully transformed it into a thriving institution (later Tuskegee Uni�  versity). He became perhaps the most prominent African American leader  of his time. His controversial conviction that African Americans could  best gain equality in the U.S. by improving their economic situation  through education rather than by demanding equal rights was termed the  Atlanta Compromise. His books include Up from Slavery (1901).</p><p>Washington, D.C. City (pop., 2000: 572,059), capital of the U.S. It  is coextensive with the District of Columbia. Situated at the navigational  head of the Potomac River, between Maryland and Virginia, it has an area  of 69 sq mi (179 sq km). The site was chosen by George Washington in  1790 as a political compromise that satisfied both Northern and Southern  states. Designed by Pierre-Charles V Enfant, it is one of the few cities in  the world planned expressly as a national capital. The federal government  occupied it in 1800. British troops burned the city (1814) during the War  of 1812. With the annexation of Georgetown in 1878, the city became  coterminous with the District of Columbia. Significant buildings include  the Capitol, White House, and Library of Congress.

Praised for his portrayal of the title character in Spike Lee�s  Malcolm X (1992), he became one of the most popular leading men of  the 1990s in films such as Philadelphia (1993), Devil in a Blue Dress  (1995), and He Got Game (1998). For his performance in Training Day  (2001), Washington became only the second African American to win an  Oscar for best actor. In 2002 he made his directorial debut with Antwone  Fisher.</p><p>Washington, Dinah orig. Ruth Lee Jones (b. Aug. 29, 1924, Tus�  caloosa, Ala., U.S.�d. Dec. 14, 1963, Detroit, Mich.) U.S. singer. Wash�  ington sang in church choirs as a child. She joined Lionel Hampton�s band  in 1943, embarking on a solo career in 1946. Her recordings encompassed  a wide variety of idioms including rhythm and blues, jazz, and country music;  her �What a Difference a Day Makes� (1959) was a pop hit. Known as  �Queen of the Blues,� she combined precise diction and intonation with  an alternately gentle and brassy vocal timbre, and her voice was remark�  able for its clarity and projection. She had remarkable vocal control. Even  after she crossed over to the popular (pop) music market, in which she  had her greatest commercial success, Washington retained many of her  earlier fans because of her passionate, supple style.</p><p>Washington, George (b. Feb. 22, 1732, Westmoreland county,  Va.�d. Dec. 14, 1799, Mount Vernon, Va., U.S.) American Revolution�  ary commander-in-chief (1775-83) and first president of the U.S. (1789�  97). Born into a wealthy family, he was educated privately. In 1752 he  inherited his brother�s estate at Mount Vernon, including 18 slaves; their  ranks grew to 49 by 1760, though he disapproved of slavery. In the French  and Indian War he was commissioned a colonel and sent to the Ohio Ter�  ritory. After Edward Braddock was killed, Washington became commander  of all Virginia forces, entrusted with defending the western frontier (1755-  58). He resigned to manage his estate and in 1759 married Martha Dan-  dridge Custis (1731-1802), a widow. He served in the House of Burgesses  (1759-74), where he supported the colonists� cause, and later in the Con�  tinental Congress (1774-75). In 1775 he was elected to command the  Continental Army. In the ensuing American Revolution, he proved a bril�  liant commander and a stalwart leader, despite several defeats. With the  war effectively ended by the capture of Yorktown (1781), he resigned his  commission and returned to Mount Vernon (1783). He was a delegate to  and presiding officer of the Constitutional Convention (1787) and helped  secure ratification of the Constitution in Virginia. When the state electors  met to select the first president (1789), Washington was the unanimous  choice. He formed a cabinet to balance sectional and political differences  but was committed to a strong central government. Elected to a second  term, he followed a middle course between the political factions that later  became the Federalist Party and the Democratic Party. He proclaimed a  policy of neutrality in the war between Britain and France (1793) and  sent troops to suppress the Whiskey Rebellion (1794). He declined to serve  a third term (thereby setting a 144-year precedent) and retired in 1797  after delivering his �Farewell Address.� Known as the �father of his coun�  try,� he is universally regarded as one of the greatest figures in U.S. his�  tory.</p><p>Washington, Harold (b. April 15, 1922, Chicago, Ill., U.S.�d. Nov.  25, 1987, Chicago) U.S. politician and mayor of Chicago (1983-87). He  practiced law and served as a city attorney (1954-58). He was elected  successively to the Illinois legislature (1965-76), the state senate (1976-  80), and the U.S. House of Representatives (1980-83). In 1983 he cam�  paigned for mayor of Chicago on a platform of reform and an end to city  patronage; with his election, he become the first African American to hold  that post. He was reelected to a second term in 1987 but died soon after.</p><p>Washington, Mount Peak in the Presidential Range of the White  Mountains, northern New Hampshire. Reaching an elevation of 6,288 ft  (1,917 m), it is the highest point in the northeastern U.S. and is noted for  its extreme weather conditions; the world�s highest wind velocity (231  mph [372 kph]) was recorded there in 1934.

(1921�  22), to limit the naval arms race and negotiate Pacific security agreements.  Several major and minor treaty agreements were drafted and signed: the  Four-Power Pact (signed by Britain, Japan, France, and the U.S.) stipu�  lated mutual consultation regarding any issue in the Pacific and affirmed  respect for the Pacific territories of signatory nations. The Five-Power  Naval Limitation Treaty (which Italy also signed) imposed proportional  limits on the number of warships each signatory nation could maintain  and mandated some actual disarmament; it lapsed in 1936 when Japan  was refused equality with the U.S. and Britain. Another agreement regu�  lated the use of submarines and outlawed poison gas in warfare. A Nine-  Power Pact (with The Netherlands, Portugal, Belgium, and China)  affirmed China�s sovereignty.</p><p>Washington Monument Obelisk in Washington, D.C., U.S.,  honouring George Washington, the first president of the United States.  Based on a design by Robert Mills (b. 1781�d. 1855), it was built  between 1848 and 1884. It is constructed of granite faced with Maryland  marble and is some 555.5 ft (169.3 m) high, the world�s tallest masonry  structure. Inserted in the interior walls are more than 190 carved stones  presented by various individuals, cities, states, and foreign countries. It  is located on grounds that are a westward extension of the Mall. The top  can be reached by elevator or by an interior iron stairway. It underwent a  major restoration in the 1990s and reopened in 2001.</p><p>Washington Post, The Morning daily newspaper published in Wash�  ington, D.C., the dominant paper in the U.S. capital and one of the nation�s  leading newspapers. Established in 1877 as a Democratic Party organ, it  changed orientation and ownership several times and faced constant eco�  nomic problems until financier Eugene Meyer (1875-1959) purchased it  in 1933. Under the leadership of Meyer, his son-in-law Philip L. Graham  (publisher from 1946 until his death in 1963), and his daughter, Katharine  Graham (publisher from 1969-79), it acquired domestic and international  prestige, especially in its coverage of the Watergate scandal. Donald E.  Graham was named publisher in 1979. The newspaper is known for its  sound and independent editorial stance and thorough, accurate reporting.</p><p>Washington University Private university in St. Louis, Mo.

The abdomen is attached to the thorax by a slender  petiole, or �waist,� and the female�s abdomen has a formidable stinger.  Most species are solitary; about 1,000 species are highly social; and some  may be either social or solitary. Adults feed primarily on nectar. Most  solitary wasps nest in tunnels in the ground and feed larvae with para�  lyzed insects or spiders. The paperlike nest of social wasps (family Vesp-  idae) consists of chewed plant material mixed with saliva and arranged  in adjacent hexagonal cells. The female lays one egg in each cell and pro�  visions it with a macerated caterpillar. Successive generations may enlarge  the nest and care for the young.</p><p>Wassermann \'va-s3r-,man,\ English Vwa-sor-manV August von  (b. Feb. 21, 1866, Bamberg, Bavaria�d.

The first watches appeared shortly after 1500, when the  mainspring (see spring) was invented as a replacement for weights in  driving CLOCKS. The progressive miniaturization of electronic components  in recent decades has made possible the development of all-electronic  watches, in which the necessary transistors, resistors, capacitors, and other  elements are all on one or several miniature integrated circuits, or chips.  Such circuitry enables them to perform several timekeeping functions and  also makes possible digital readouts of the time.</p><p>water Inorganic compound composed of hydrogen and oxygen (H 2 0),  existing in liquid, gas (steam, water vapour), and solid (ice) states. At room  temperature, water is a colourless, odourless, tasteless liquid. One of the  most abundant compounds, water covers about 75% of Earth�s surface.  Life depends on water for virtually every process, its ability to dissolve  many other substances being perhaps its most essential quality. Life is  believed to have originated in water (the world�s oceans or smaller bod�  ies), and living organisms use aqueous solutions (including blood and  digestive juices) as mediums for carrying out biological processes.  Because water molecules are asymmetric and therefore electric dipoles,  hydrogen bonding between molecules in liquid water and in ice is impor�  tant in holding them together. Many of water�s complex and anomalous  physical and chemical properties (high melting and boiling points, viscos�  ity, surface tension, greater density in liquid than in solid form) arise from  this extensive hydrogen bonding. Water undergoes dissociation to the ions  H + (or H 3 0 + ) and OH - , particularly in the presence of salts and other  solutes; it may act as an acid or as a base. Water occurs bound (as water  of hydration) in many salts and minerals. It has myriad industrial uses,  including as a suspending agent (papermaking, coal slurrying), solvent,  diluting agent, coolant, and source of hydrogen; it is used in filtration,  washing, steam generation, hydration of lime and cement, textile process�  ing, sulfur mining, hydrolysis, and hydraulics, as well as in beverages and  foods. See also hard water; heavy water.</p><p>water bloom Dense aquatic accumulation of microscopic organisms  produced by an abundance of nutrients in surface water coupled with  adequate sunlight for photosynthesis. The microorganisms or the toxic  substances they release may discolour the water, exhaust its oxygen con�  tent, poison aquatic animals and waterfowl, and irritate the skin and res�  piratory tract of humans. Single species of algae, diatoms, or  dinoflagellates, reproducing every few hours, may dominate a bloom�s  population; the number of individuals per quart (litre) of water, normally  about 1,000, can increase to 60 million. Blooms of the dinoflagellate  genus Gymnodinium cause red tides. The Red Sea is named for the occa�  sional blooms of the alga Trichodesmium erythraeum. See also water pol�  lution.</p><p>water buffalo or Indian buffalo Any of three subspecies of oxlike  bovid (species Bubalus bubalis). Two have been domesticated in Asia since</p><p>the earliest recorded history. The animal is named for its ability to work  on waterlogged land and in humid climates. The largest breeds stand 5-6  ft (1.5-1.8 m), is up to 9 ft (2.8 m) long, and may weigh over 2,000 lb  (900 kg). The dull black or dark gray body has little hair. The horns spread  outward and upward, measuring up to 7 ft (2 m) across. One subspecies,  the swamp buffalo, is the principal draft animal of southern China and  South and Southeast Asia. Another, the river buffalo, is used for dairy and  meat production and draft work in southern and South Asia and Egypt.  The third subspecies is the wild water buffalo, of which only a few dozen  herds remain. It is larger than domestic buffaloes and is sometimes  referred to as a separate species {B. arnee).</p><p>water chestnut Any of several perennial water plants of the genus  Trapa (family Trapaceae), native to Europe, Asia, and Africa, or their  edible, nutlike fruit. The water caltrop (T. natans) has two sets of leaves�  long, feathery, rootlike, submerged leaves and a loose rosette of floating  leaves attached to leafstalks 2-4 in (5-10 cm) long. The small fruit usu�  ally has four spiny angles. The Chinese water chestnut (. Eleocharis tubero-  sus or E. dulcis) is a member of the sedge family.</p><p>water clock or clepsydra Vklep-so-droX Ancient device for measur�  ing time by the gradual flow of water. One form, used by North Ameri�  can Indians and some African peoples, consisted of a small boat or floating  vessel that shipped water through a hole until it sank. In another form,  water escaped through a hole in a vessel marked with graduated lines;  specimens from Egypt date from the 14th century bc. The Romans  invented a clepsydra consisting of a cylinder into which water dripped  from a reservoir; a float provided readings against a scale on the cylinder  wall. Galileo used a mercury clepsydra to time his experimental falling  bodies. See also clock.</p><p>water flea Any of about 450 species (order Anomopoda) of micro�  scopic, mostly freshwater crusta�  ceans distributed worldwide. Species  in the genus Daphnia are ubiquitous  in Europe and North America. Water  fleas have a discrete head that bears  antennae. The carapace (shell)  encloses all or most of the body,  except on the predatory giant Lep-  todora (up to 0.7 in. [18 mm] long),  whose carapace is just a small brood  sac. Most species swim by powerful  strokes of the antennae, sometimes  producing a hopping-and-sinking  motion. All but a few predatory spe�  cies use specialized thoracic limbs to filter organic matter from the water.

In some species the leaves are  also submerged. Showy, solitary,  cuplike flowers with numerous spi�  rally arranged petals are borne at or  above the water surface on the long  stalks. The genus Nymphaea  includes the water lilies proper (or  water nymphs). The common North  American white water lily, pond lily,  or toad lily is N. odorata. The LOTUS  of ancient Egyptian art was usually  the blue lotus ( N. caerulea). The  largest water lilies are two species  that make up the tropical South  American genus Victoria ; the Santa  Cruz water lily ( V. cruziana ) has  leaves 2-6 ft (60-180 cm) in diam�  eter. Water lilies provide food for fish  and wildlife but sometimes cause drainage problems because of their rapid  growth. Many varieties have been developed for ornamental use in gar�  den pools and conservatories.</p><p>water moccasin or cotton mouth Either of two species of pit viper  that inhabits marshy lowlands of the southeastern U.S. and Mexico. The  U.S. species ( Agkistrodon piscivorus ) is called a cottonmouth because it  threatens with the mouth open, showing the white interior. It is up to 5 ft  (1.5 m) long and is completely black or brown with darker crossbands. A  dangerous snake with a potentially lethal bite, it tends to stand its ground  or move slowly away when alarmed. It will eat almost any small animal,  including turtles, fishes, and birds. See also copperhead.</p><p>water ouzel See dipper</p><p>water pollution State resulting when substances are released into a  body of water, where they become dissolved or suspended in the water  or deposited on the bottom, accumulating to the extent that they over�  whelm its capacity to absorb, break down, or recycle them, and thus inter�  fering with the functioning of aquatic ecosystems. Contributions to water  pollution include substances drawn from the air (see acid rain), silt from  soil erosion, chemical fertilizers and pesticides, runoff from septic tanks,  outflow from livestock feedlots, chemical wastes (some toxic) from indus�  tries, and sewage and other urban wastes from cities and towns. A com�  munity far upstream in a watershed may thus receive relatively clean  water, whereas one farther downstream receives a partly diluted mixture  of urban, industrial, and rural wastes. When organic matter exceeds the  capacity of microorganisms in the water to break it down and recycle it,  the excess of nutrients in such matter encourages algal water blooms.  When these algae die, their remains add further to the organic wastes  already in the water, and eventually the water becomes deficient in oxy�  gen. Organisms that do not require oxygen then attack the organic wastes,  releasing gases such as methane and hydrogen sulfide, which are harm�  ful to the oxygen-requiring forms of life. The result is a foul-smelling,  waste-filled body of water. See also eutrophication.</p><p>water polo Sport played in a swimming pool by teams of seven with  a buoyant ball resembling a football (soccer ball). The ball may be car�  ried or thrown, and a point is scored when the ball is placed in the oppos�  ing team�s goal. The name derives from a mid-19th-century version of  the sport in which players rode barrels and struck the ball with sticks. A  rough and demanding game, it is played by both men and women. Mod�  ern water polo was introduced as an Olympic sport in 1900.</p><p>European species are less water-dependent and lay eggs. In defense they  inflate the head, strike, and release a foul secretion.

Ancient systems included wells, storage  reservoirs, canals and aqueducts, and water-distribution systems. Highly  advanced systems appeared c. 2500 bc and reached their peak in the  Roman aqueduct system. In the Middle Ages, water supplies were largely  neglected and epidemics caused by waterborne organisms were common.  In the 17th-18th century, distribution systems utilizing cast-iron pipes,  aqueducts, and pumps began to be installed. The link between polluted  water and disease came to be understood in the 19th century, and treat�  ment methods such as slow sand filtration and disinfection with chlorine  were introduced. Modem reservoirs are formed usually by constructing  dams near the collection point of mountain-water runoff or across rivers.  After the water reaches collection points, it is treated to improve its qual�  ity; it is then pumped either directly into a city or town�s distribution sys�  tem or to an elevated storage location, such as a water tank.

The water table separates the groundwater zone (zone of satu�  ration) that lies below it from the zone of aeration that lies above it. The  water table fluctuates both with the seasons and from year to year because  it is affected by climatic variations and by the amount of precipitation  used by vegetation. It also is affected by withdrawing excessive amounts  of water from wells or by recharging them artificially.

Waterfowl  feed by dabbling, diving, or grazing. Most species are social and have an  array of formal displays and group cohesion signals. Almost all breed in  water. The female usually selects the nest site, builds the nest from any  vegetation within reach, and incubates the 3-12 eggs. Shortly after hatch�  ing, the young imprint on their mother (see imprinting). Many species are  migratory.</p><p>Watergate scandal (1972-74) Political scandal involving illegal  activities by Pres. Richard Nixon�s administration. In June 1972 five bur�  glars were arrested after breaking into the Democratic Party�s national  headquarters at the Watergate Hotel complex in Washington, D.C. Within  a few days of their arrest at the Watergate, charges of burglary and wire�  tapping were brought against the five and two others, including a former  White House aide and G. Gordon Liddy, general counsel for the Com�  mittee to Reelect the President. Nixon and his aides steadfastly denied  that anyone in the administration had been involved, despite persistent  press reports to the contrary, and in November 1972 Nixon was easily  reelected. In January 1973 the trial of the burglars was held before Judge  John Sirica; five pleaded guilty and two were convicted by a jury. Siri�  ca�s direct questioning of witnesses revealed details of a cover-up by H.R.  Haldeman, John D. Ehrlichman, and John W. Dean. They and Attorney  General Richard G. Kleindienst resigned in April. The new attorney gen�  eral, Elliot L. Richardson (1920-98), appointed Archibald Cox (b. 1912)  as special prosecutor. A Senate committee under Samuel Ervin held tele�  vised hearings in which the existence of tapes of conversations in the  president�s office was disclosed. Cox and Ervin subpoenaed the tapes, but  Nixon refused to relinquish them and ordered Cox fired (Oct. 20, 1973).  Richardson resigned in protest, and the public outcry eventually forced  Nixon to surrender the tapes (December 8), which revealed clear signs of  his involvement in the cover-up. In July 1974 the Judiciary Committee  of the House of Representatives passed three articles of impeachment  against Nixon. On August 5 Nixon supplied three tapes that clearly impli�  cated him in the cover-up. Though Nixon continued to insist that he had  not committed any offenses, he resigned on Aug. 8, 1974. He was par�  doned a month later by his successor, Gerald Ford.</p><p>Waterloo, Battle of (June 18, 1815) Final defeat of Napoleon and  French forces in the Napoleonic Wars. The battle was fought near Water�  loo village, south of Brussels, during the Hundred Days of Napoleon�s res�  toration, by Napoleon�s 72,000 troops against the duke of Wellington�s  combined Allied army of 68,000 aided by 45,000 Prussians under Geb-  hard von Blucher. After the French defeated the Prussians at Ligny and  held Wellington at Quatre-Bras in secondary battles on June 16, Napo�  leon�s marshals, including Michel Ney, failed to eliminate either enemy  while they were separated. Napoleon delayed his attack at Waterloo until  midday, to allow the ground to dry, which enabled Bliicher�s main force  to escape the pursuing French and join Wellington. Four French attacks</p><p>on the Allied centre failed to break through, and Napoleon had to move  troops to meet the Prussian flanking attack. When Ney succeeded in cap�  turing a farmhouse at the centre of the Allied line, his call to Napoleon  for reinforcements was refused. Wellington and his forces, though vul�  nerable after heavy losses, repulsed the final French assault and turned to  advance against the French, forcing them into a disorganized retreat. The  French suffered 25,000 killed and wounded, and 9,000 were captured;  Wellington�s casualties were 15,000, and Bliicher�s were about 8,000.  Four days later, Napoleon abdicated for the last time.</p><p>Waterloo, University of Public university in Waterloo, Ont., Can.,  founded in 1957. It has faculties of applied health sciences, arts, engi�  neering, environmental studies, mathematics, and science, as well as  schools of accounting, architecture, optometry, and urban and regional  planning. Special facilities include museums of optometry and of games.</p><p>watermelon Succulent fruit of Citrullus lanatus (formerly C. vul�  garis), in the gourd family, native to tropical Africa and cultivated on  every continent except Antarctica. The vines spread across the ground  with branched tendrils, deeply cut leaves, and light-yellow flowers. Each  vine bears 2-15 large, reddish, white, or yellow, sweet, very juicy fruits  with flat black seeds. Varieties differ in flesh color, shape, and rind thick�  ness. The rind may be preserved as a pickle.</p><p>waterpower Power produced by a stream of water as it turns a wheel  or similar device. The waterwheel, probably invented in the 1st century  bc, was widely used throughout the Middle Ages and into modem times  for grinding grain, operating bellows for furnaces, and other purposes.  The more compact water turbine, which passes water through a series of  fixed and rotating blades, was introduced in 1827. Water turbines, used  originally for direct mechanical drive for irrigation, now are used almost  exclusively to generate hydroelectric power.</p><p>Waters, Ethel (b. Oct. 31, 1896/1900. Chester, Pa., U.S.�d. Sept. 1,  1977, Chatsworth, Calif.) U.S. blues and jazz singer and actress. She was  a professional singer by age 17, and she recorded with jazzmen such as  Duke Ellington and Benny Goodman in the 1930s. She made her Broad�  way debut in the Africana revue (1927) and later had a lead role in Black�  birds (1930). In 1933 she appeared in Irving Berlin�s musical As Thousands  Cheer, in which she sang �Heat Wave� and �Suppertime.� Her later stage  successes included Cabin in the Sky (1940; film, 1943) and The Member  of the Wedding (1950; film, 1952). She also acted in films such as Pinky  (1949) and The Sound and the Fury (1959).</p><p>Waters, Muddy orig. McKinley Morganfield (b. April 4, 1915,  Rolling Fork, Miss., U.S.�d. April 30, 1983, Westmont, Ill.) U.S. blues  guitarist and singer. He grew up in the cotton country of Mississippi and  taught himself harmonica as a child. He later took up guitar, eagerly  absorbing the classic delta blues styles of Robert Johnson and Son House.  He was first recorded in 1941 by archivist Alan Lomax (see John Lomax).  In 1943 he moved to Chicago; there he broke with the country blues style  by playing over a heavy dance rhythm, adopting the electric guitar and  adding piano and drums while retaining a moan-and-shout vocal style and  lyrics that were by turns mournful, boastful, and risque. The result came  to be known as urban blues, from which sprang in large part later forms  such as rock music and soul music. A surge in interest in the roots of popu�  lar music in the early 1960s brought Waters widespread fame, and he per�  formed internationally into the 1970s.</p><p>waterskiing Sport of planing and jumping on water skis, broad ski�  like runners that a rider wears while being towed by a motorboat. The  sport originated in the U.S. in the 1920s. International competitions have  been held since 1946. Single-ski slalom competition is held on a course  consisting of a specified number of buoys around which the skier must  negotiate. Jumping competitions employ a r&amp; skiers are judged for  distance and style. Barefoot and trick skiing are also part of some com�  petitions. A later development in waterskiing, wakeboarding began in the  U.S. in the 1980s when surfers began riding their boards as they were  pulled behind boats. Since the mid 1990s wakeboarding has been an event  at both the Gravity Games and the X Games (see extreme sports) and has  become the fastest-growing water sport worldwide.</p><p>Waterton Lakes National Park Mountain recreational area, west�  ern Canada.

He learned English  at a mission school and helped publish the Cherokee Phoenix, a tribal  newspaper. In 1835 he joined three other Cherokee chiefs to sign the Treaty  of New Echota, which surrendered Cherokee lands in Georgia and forced  the tribe to move to Indian Territory in present-day Oklahoma. In the  American Civil War he raised a mounted Cherokee rifle regiment and  joined the Confederate army. He directed cavalry raids on the fields and  other property of Indians who backed the Union. Promoted to brigadier  general (1864), he remained loyal to the Confederacy even after the tribe  ended its alliance. After the war, he went to Washington, D.C., as a rep�  resentative of the southern Cherokee.</p><p>Watling Street Ancient Roman road in Britain.

March 2, 1923, Stony  Fork, near Deep Gap, N.C., U.S.) U.S. country music singer, banjoist, and  guitarist. Blind from birth, Watson grew up on a farm and learned to play  guitar, banjo, and harmonica as a child. Though he did not record profes�  sionally until he was in his late 30s, he quickly rose to prominence with  his renditions of traditional and popular tunes backed by his virtuoso flat�  picking guitar style. He appeared at the 1963 Newport Folk Festival to  great acclaim. He performed for many years with his son Merle (1949-</p><p>85).</p><p>Watson, James D(ewey) (b. April 6, 1928, Chicago, Ill., U.S.) U.S.  geneticist and biophysicist. He earned his Ph.D. at Indiana University in  1950. Using X-ray diffraction techniques, he began work in Britain with  Francis Crick on the problem of DNA structure. In 1952 he determined the  structure of the protein coat surrounding the tobacco mosaic virus. In early  1953 he determined that the essential DNA components, four organic  bases, must be linked in definite pairs, a discovery that enabled Watson  and Crick to formulate a double-helix molecular model for DNA. In 1962  the two scientists and Maurice Wilkins shared the Nobel Prize. Watson�s  The Double Helix (1968), a best-selling personal account of the DNA dis�  covery, aroused controversy. He taught at Harvard University (1955-76)  and served as director of the Carnegie Institute�s laboratory at Cold Spring  Harbor (1968-94). See also Rosalind Franklin.</p><p>Watson, John B(roadus) (b. Jan. 9, 1878, Travelers Rest, near  Greenville, S.C., U.S.�d. Sept. 25, 1958, New York, N.Y.) U.S. psy�  chologist. Trained at the University of Chicago, Watson taught psychol�  ogy at Johns Hopkins University (1908-20). He is remembered for  codifying and publicizing behaviourism. In his epoch-making article,  �Psychology as a Behaviorist Views It� (1913), he asserted that psychol�  ogy should restrict itself to the objective, experimental study of the rela�  tions between environmental events and human behaviour. In Behavior  (1914) he argued for the use of animal subjects in studying reflexes and  conditioned responses, and in Psychology from the Standpoint of a Behav�  iorist (1919) he extended the principles and methods he employed in ani�  mal experiments. In 1920 he left academia to enter the advertising  business.</p><p>Watson, Thomas J(ohn), Sr. (b. Feb. 17, 1874, Campbell, N.Y.,  U.S.�d. June 19, 1956, New York, N.Y.) U.S. industrialist. He went to  work for the National Cash Register Co. in 1899. In 1914 he became  president of the company that in 1924 became International Business  Machines Corporation (IBM), which he built into the world�s largest  manufacturer of electric typewriters and data-processing equipment.  Backing an aggressive research-and-development program, he assembled  a highly motivated, well-trained, and well-paid staff, gave pep talks,  enforced a strict dress code, and posted the now-famous �Think� sign in  company offices. In the 1930s and �40s he pursued international trade,  extending IBM�s influence worldwide. Active in civic affairs, he was</p><p>noted for his efforts on behalf of the arts and world peace.

He became one of the  sport�s dominant figures in the 1970s and early �80s, winning the British  Open (1975, 1977, 1980, 1982, 1983), the Masters (1977, 1981), and the  U.S. Open (1982).</p><p>Watson-Watt, Sir Robert Alexander (b. April 13, 1892, Brechin,  Scot.�d. Dec. 5, 1973, Inverness) Scottish physicist. He began as a  meteorologist working on devices for locating thunderstorms. As head of  the radio department of Britain�s National Physical Laboratory (1935), he  worked on aircraft radio location and could locate planes at a distance of  about 80 mi (110 km) by beaming radio waves at them, receiving reflec�  tions of the waves, and calculating distance by elapsed time. This led to  the design of the world�s first practical radar system, a vital element in  the defense of Britain against German air raids during World War II. His  other contributions include a cathode-ray direction finder used to study  atmospheric phenomena, research in electromagnetic radiation, and  inventions used for flight safety.</p><p>Watt, James (b. Jan. 19, 1736, Greenock, Renfrewshire, Scot.�d.  Aug. 25, 1819, Heathfield Hall, near  Birmingham, Warwick, Eng.) Scot�  tish engineer and inventor. Though  largely self-taught, he began work  early as an instrument maker and  later as an engineer on the Forth and  Clyde Canal. Watt�s major improve�  ment to Thomas Newcomen�s steam  engine was the use of a separate con�  denser (1769), which reduced the  loss of latent heat and greatly  increased its efficiency. With Mat�  thew Boulton he began manufacture  of his new engine in 1775. In 1781  he added rotary motion (a so-called  sun-and-planet gear) to replace the  up-and-down action of the original  engine. In 1782 he patented the  double-acting engine, in which the  piston pushed as well as pulled. This  engine required a new method of rig�  idly connecting the piston to the  beam, a problem he solved in 1784  with an arrangement of connected  rods that guided the piston rod in a perpendicular motion. His application  of the centrifugal governor for automatic control of the speed of the engine  (1788) and his invention of a pressure gauge (1790) virtually completed  the Watt engine, which had immense consequences for the Industrial Revo�  lution. He introduced the concept of horsepower; the watt, a unit of power,  is named for him.</p><p>Watteau \va-'to,\ English \wa-'to\, (Jean-) Antoine (b. Oct. 10,  1684, Valenciennes, France�d. July 18, 1721, Nogent-sur-Marne) French  painter. Son of a roof tiler in Valenciennes, he was apprenticed to a local  artist. At 18 he moved to Paris, where he worked for a series of painters;  one of them was a theatrical scenery painter, and much of Watteau�s work  consequently embraced the artifice of the theatre, particularly the comme-  dia dell'arte and the ballet. His works typified the lyrically charming and  graceful Rococo style. The greatest, his Pilgrimage to the Island of  Cythera, depicts pilgrims setting out for (or departing from) the mythic  island of love and was his presentation piece when he was inducted into  the academy in 1717. The academicians, unable to fit him into any of the  recognized categories, welcomed him as a painter of fetes galantes  (�elegant festivities�), an important new genre to which countless later  Rococo pictures belong.</p><p>wattle See acacia</p><p>Watts, Andre (b.

Watts studied at the Dis�  senting Academy at Stoke Newington, London, and he later became pastor  of Mark Lane Independent (i.e.. Congregational) Chapel. His collections  of sacred lyrics include Horae Lyricae (1706), Hymns and Spiritual Songs  (1707), and The Psalms of David Imitated in the Language of the New  Testament (1719). His hymns, numbering more than 600, became known  throughout Protestant Christendom; they include �When I Survey the  Wondrous Cross,� �O God, Our Help in Ages Past,� �Joy to the World,�  and �Jesus Shall Reign.� A man of great erudition, he published books on  a range of subjects.</p><p>Watusi See Tutsi</p><p>wave Propagation of disturbances from place to place in a regular and  organized way. Most familiar are surface waves that travel on water, but  sound, light, and the motion of subatomic particles all exhibit wavelike  properties. In the simplest waves, the disturbance oscillates periodically  (see periodic motion) with a fixed frequency and wavelength. Mechanical  waves, such as sound, require a medium through which to travel, while  electromagnetic waves (see electromagnetic radiation) do not require a  medium and can be propagated through a vacuum. Propagation of a wave  through a medium depends on the medium�s properties. See also seismic  WAVE.</p><p>wave In oceanography, a ridge or swell on the surface of a body of water,  normally having a forward motion distinct from the motions of the par�  ticles that compose it. Ocean waves are fairly regular, with an identifiable  wavelength between adjacent crests and with a definite frequency of oscil�  lation. Waves result when a generating force (usually the wind) displaces  surface water and a restoring force returns it to its undisturbed position.  Surface tension alone is the restoring force for small waves. For large  waves, gravity is more important.</p><p>wave-cut platform or abrasion platform Gently sloping rock  ledge that extends from the high-tide level at a steep cliff base to below  the low-tide level. It develops as a result of wave abrasion; beaches pro�  tect the shore from abrasion and therefore prevent the formation of plat�  forms. A platform is broadened as waves erode a notch at the base of the  sea cliff, causing overhanging rock to fall. As the sea cliffs are attacked,  weak rocks are quickly eroded, leaving the more resistant rocks as pro�  trusions.</p><p>wave front Imaginary surface that represents corresponding points of  waves vibrating in unison. As identical waves from the same source travel  through a homogeneous medium, corresponding crests and troughs are in  phase at any instant; that is, they have completed the same fraction of their  periodic motion. Any surface drawn through all points of the same phase  constitutes a wave front.</p><p>wave function Variable quantity that mathematically describes the  wave characteristics of a particle. It is related to the likelihood of the par�  ticle being at a given point in space at a given time, and may be thought  of as an expression for the amplitude of the particle wave, though this is  strictly not physically meaningful. The square of the wave function is the  significant quantity, as it gives the probability for finding the particle at a  given point in space and time. See also wave-particle duality.</p><p>wave-particle duality Principle that subatomic particles possess some  wavelike characteristics, and that electromagnetic waves, such as light,  possess some particlelike characteristics. In 1905, by demonstrating the  photoelectric EFFECT, Albert Einstein showed that light, which until then had  been thought of as a form of electromagnetic wave (see electromagnetic  radiation), must also be thought of as localized in packets of discrete  energy (see photon). In 1924 Louis-Victor Broglie proposed that electrons  have wave properties such as wavelength and frequency; their wavelike  nature was experimentally established in 1927 by the demonstration of  their diffraction. The theory of quantum electrodynamics combines the  wave theory and the particle theory of electromagnetic radiation.</p><p>waveguide Device that constrains the path of electromagnetic waves  (see electromagnetic radiation). It can be used to transmit power or signals  in the form of waves while minimizing power loss. Common examples  are metallic tubes, coaxial cables, and optical fibres (see fibre optics).  Waveguides transmit energy by propagating transmitted electromagnetic  waves through the inside of a tube to a receiver at the other end. Metal  waveguides are used in such technologies as microwave ovens, radar sys�  tems, radio relay systems, and radio telescopes.</p><p>wavelength Distance between corresponding points of two consecu�  tive waves. �Corresponding points� refers to two points or particles that  have completed identical fractions of their periodic motion. In transverse  waves, wavelength is measured from crest to crest or from trough to  trough. In longitudinal waves, it is measured from compression to com�  pression or from rarefaction to rarefaction. Wavelength, X, is equal to the  speed v of a wave in a medium divided by its frequency f or X = v/f</p><p>Wavell Vwa-val\ (of Eritrea and of Winchester), Archibald  Percival Wavell, 1st Earl (b.

Waxes contain mostly compounds of high molecular weight (fatty  acids, alcohols, and saturated hydrocarbons). Many melt at moderate tem�  peratures and form hard films that can take a high polish. Animal and  plant waxes are esters of fatty acids and either a sterol (see steroid) or a  straight-chain higher alcohol (e.g., cetyl alcohol). Animal waxes include  beeswax; wool wax (lanolin), used in pharmaceuticals and cosmetics; and  sperm oil and spermaceti (from sperm whales), used as lubricants. Plant  waxes include carnauba wax, candelilla wax, and sugarcane wax, used in  polishes. About 90% of the waxes in commerce are recovered by de�  waxing petroleum. There are three main types: paraffin (used in candles,  crayons, paper coating, and industrial polishes and as a protective seal�  ant, lubricant, insulating agent, and antifrothing agent), microcrystalline  wax (used in paper coating), and petrolatum (used in ointments and cos�  metics).

He converted to Roman  Catholicism in 1930, and his  Catholicism is insistently reflected in  his novels from then on. After ser�  vice in World War II he led a retired  life, growing increasingly conserva�  tive and misanthropic.

The weakfish, or sea trout ( Cynoscion regalis), is a sport  fish but is usually less than 2 ft (60 cm) long. Weakfish are caught com�  mercially along the Middle Atlantic coastal states and are considered the  most economically important species in the family.

The term has been in currency since at least 1937, when it was used to  describe massed formations of bomber aircraft. Today WMDs are nuclear,  biological, or chemical weapons�frequently referred to collectively as  NBC weapons. Efforts to control the spread of WMDs are enshrined in  international agreements such as the Nuclear Non-proliferation Treaty of  1968, the Biological Weapons Convention of 1972, and the Chemical  Weapons Convention of 1993. See nuclear weapon; chemical warfare; bio�  logical WARFARE.</p><p>weapons system Any integrated system for the control and opera�  tion of a specific type of weaponry. Weapons are usually divided into two  categories, strategic and tactical. Strategic weapons strike at the seat of  an enemy�s military, economic, and political power, targeting cities, fac�  tories, military bases, transportation and communications networks, and  seats of government. Most nuclear weapons are part of strategic weapons  systems. Tactical weapons are designed instead for offensive or defensive  use at relatively short range�for example, guided missiles intended as anti�  aircraft and antitank weapons, or other weapons used in aerial and naval  combat.</p><p>weasel Any of several genera (carnivore family Mustelidae) of vora�  cious nocturnal predators found  throughout the Americas, Africa, and  Eurasia. Weasels have slender bodies  and necks, small flat heads, short  legs, clawed toes, dense short fur,  and slim pointed tails. The size and  relative length of the tail vary among  species. Their total length is 7-20 in.</p><p>(17-50 cm), and they may weigh  1�12 oz (30-350 g). The approxi�  mately 10 New World and Eurasian  species of Mustela are reddish  brown; in cold regions, their winter  coat turns white, and the pelt, especially of the stoat (M. erminea ), is called  ermine. Weasels generally hunt alone, feeding on rodents, fish, frogs, and  birds� eggs.</p><p>weather State of the atmosphere at a particular place during a short  period of time. It involves day-to-day changes in such atmospheric phe�  nomena as temperature, humidity, precipitation (type and amount), air  pressure, wind, and cloud cover. Most weather occurs in the troposphere,  but phenomena of the higher regions of the atmosphere, such as jet streams,  and geographic features, most notably mountains and large bodies of  water, also affect it. See also climate.</p><p>weather forecasting Prediction of the weather through application  of the principles of physics and meteorology. Weather forecasting predicts  atmospheric phenomena and changes on the Earth�s surface caused by  atmospheric conditions (snow and ice cover, storm tides, floods, etc.).  Scientific weather forecasting relies on empirical and statistical tech�  niques, such as measurements of temperature, humidity, atmospheric pres�  sure, wind speed and direction, and precipitation, and computer-controlled  mathematical models.</p><p>weather modification Deliberate or inadvertent alteration of atmo�  spheric conditions by human activity, sufficient to modify the weather on  a local or regional scale. Deliberate alterations include covering plants to  keep them warm at night, seeding clouds to induce or augment precipi�  tation, and firing silver-iodide particles into clouds to suppress or mitigate  hail and to reduce fog at airports. Inadvertent alterations are the result of  industrialization and urbanization, which have added billions of tons of  carbon dioxide and other gases to the atmosphere (see acid rain, global  WARMING, GREENHOUSE EFFECT).</p><p>weathering Physical disintegration and chemical decomposition of  rocks, minerals, and immature soils at or near the Earth�s surface. Physi�  cal, chemical, and biological processes induced or modified by wind,  water, and climate cause the changes. Weathering is distinguished from  erosion in that no transportation of material is involved. A broader appli�  cation of erosion, however, includes weathering as a component. Weath�  ering is also distinguished from metamorphism, which usually takes place  deep in the crust at much higher temperatures and elevated pressures.</p><p>JOHN H.

He helped form the People�s Party (see  Populist movement) and was its candidate for president in 1892, receiving  more than 1 million popular votes and 22 electoral votes.

Sept. 24, 1760, Shrewsbury) English dancer and teacher, known as �the  father of English pantomime.� From 1700 to 1736 he performed and pro�  duced his dance dramas at the Drury Lane and Lincoln�s Inn Fields the�  atres. His libretto for The Loves of Mars and Venus (1717) was the first  published dance drama and displayed the integration of plot and dance  that was later developed by Jean-Georges Noverre and Gasparo Angiolini  as the ballet d�action.</p><p>Weaver, Warren (b. 1894, Reedsburg, Wise., U.S.�d. 1978) U.S.  mathematician. He studied at the University of Wisconsin, taught there  (1920-32), and directed the Rockefeller Foundation�s Natural Science  Division (1932-55). He is considered the first person to propose using  electronic computers for the translation of natural languages. In a 1949  memo, he proposed that statistical techniques from the field of informa�  tion theory could be used to enable computers to translate text from one  natural language to another automatically. His proposal was based on the  assumption that a document in a human language can be viewed as hav�  ing been written in code, which can be broken like other codes.</p><p>weaving Production of fabric by interlacing two sets of yarns so that  they cross each other, normally at right angles, usually accomplished with  a hand- or power-operated loom. In weaving, lengthwise yarns are called  warp and crosswise yarns are called weft, or filling. Most woven fabrics  are made with their outer edges finished in a manner that avoids raveling  (because the weft yarn turns around instead of ending in a cut end). These  edges, called selvages, run lengthwise, parallel to the warp yams. The  three basic weaves are plain or tabby (weft threads go over one warp  thread, then under one), twill, and satin. Fancy weaves, such as pile, Jac�  quard, dobby, and leno, require more complicated looms or special loom  attachments.

April 30, 1943, Liphook, Hampshire) English social�  ist economists. Sidney was a civil service clerk when George Bernard  Shaw induced him to join the Fabian Society in 1885. He wrote the first  Fabian tract. Facts for Socialists (1887), and took to lecturing on social�  ism. In 1891 he met Beatrice, author of The Cooperative Movement in  Great Britain (1891), and they were married in 1892. Together they wrote  the influential The History of Trade Unionism (1894) and Industrial  Democracy (1897). As a member of the London County Council (1892�  1910), Sidney effected extensive reforms in public education. The Webbs  cofounded the London School of Economics and helped reorganize the  University of London. As a member of the Poor Laws commission (1905-  09), Beatrice wrote a report that anticipated the welfare state. In 1914 they  joined the Labour Party, and Sidney wrote its influential policy statement,  Labour and the New Social Order (1918). Sidney served in Parliament  (1922-29) and as colonial secretary (1929-31), having been created</p><p>Baron Passfield of Passfield Corner in 1929. Impressed by the Soviet  Union after their trip in 1932, the Webbs wrote Soviet Communism: A  New Civilisation?

Nov. 18,  1786, Eutin, Holstein�d. June 5, 1826, London, Eng.) German composer.  Son of a musician and a theatre manager, and first cousin to Wolfgang  Amadeus Mozart�s wife, he was born with a deformed hip and was never  strong. He took composition lessons with Michael Haydn (1737-1806)  and with Abbe Vogler (1749-1814), who recommended him for a post in  Breslau (1804-06). His operas began to have success, and he took over  direction of the Prague Opera (1813-16), which he saved from ruin, but  finding little time for composition, he resigned. Showing signs of the  tuberculosis that would kill him, he began to compose more prolifically.  Appointed kapellmeister for life in Dresden, he began work on his mas�  terpiece, the opera The Freeshooter (1821), the premiere of which made  him an international star. The libretto for his next opera, Euryanthe (1823),  was so clumsy that its admirable music never succeeded, and his final  opera, Oberon (1826), composed for London, was a success there but not  elsewhere.</p><p>Weber Vva-bsrV Max (b. April 21, 1864, Erfurt, Prussia�d. June 14,  1920, Munich, Ger.) German sociologist and political economist. Son of  a wealthy liberal politician and a Calvinist mother, Weber was a compul�  sively diligent scholar who suffered occasional nervous collapses. Insights  derived from his own experience inform his most famous and controver�  sial work, The Protestant Ethic and the Spirit of Capitalism (1904-05),  which examines the relationship between Calvinist (or Puritan) morality,  compulsive labour, bureaucracy, and economic success under capitalism  (see Protestant ethic). Weber also wrote penetratingly on social phenom�  ena such as charisma and mysticism, which he saw as antithetical to the  modern world and its underlying process of rationalization. His efforts  helped establish sociology as an academic discipline in Germany, and his  work continues to stimulate scholarship. Through his insistence on the  need for objectivity and his analysis of human action in terms of moti�  vation, he profoundly influenced sociological theory. His voluminous  writings, mostly published posthumously, include Economy and Society  (2 vol., 1922-25) and General Economic History (1923).</p><p>Weber-Fechner law See Weber's law</p><p>Webern Wa-borM, Anton (Friedrich Wilhelm von) (b. Dec. 3,  1883, Vienna�d. Sept. 15, 1945, Mittersill, near Salzburg, Austria) Aus�  trian composer. He learned piano and cello as a child and earned a doctorate  in musicology at the University of Vienna, specializing in the music of the  15th-century Flemish composer Heinrich Isaac. In 1904 he and his friend  Alban Berg began composition lessons with Arnold Schoenberg, and  Webern was soon combining atonality with complex counterpoint in the  manner of Isaac, producing works distinctive for their extreme brevity and  delicacy. While Schoenberg was developing the 12-tone method (see seri-  AUSm) of composition into the 1920s, Webern was independently moving in  a similar direction. After Schoenberg presented the system in 1924, Webern  adopted it, composing relatively extended pieces such as the Symphony  (1928), Concerto (1934), and Variations for Piano (1936). He earned a liv�  ing most of his life as a conductor. During Austria�s occupation at the end  of World War II, he was accidentally shot and killed by an American sol�  dier. Though he was little appreciated during his lifetime, his works became  highly influential internationally in the postwar decades.</p><p>Weber's law Vva-borz\ or Weber-Fechner law Vfek-nor\ In psy�  chophysics, a historically important law quantifying the perception of  change in a given stimulus. Originated by the German physiologist Ernst  Heinrich Weber (1795-1878) in 1834 and elaborated by his student  Gustav Theodor Fechner, the law states that the change in a stimulus that  will be just noticeable is a constant ratio of the original stimulus. It was  later shown not to hold for extremes of stimulation.</p><p>Webster, Benjjamin Francis) (b. March 27,1909, Kansas City, Mo.,  U.S.�d. Sept. 20, 1973, Amsterdam, Neth.) U.S. tenor saxophonist.

After moving to Boston  (1816), he built a prosperous law  practice and represented Massachu�  setts in the House (1823-27). He  argued several precedent-setting  cases before the U.S. Supreme  Court, including the Dartmouth Col�  lege case, McCulloch v. Maryland,  and Gibbons v. Ogden. Elected to the  U.S. Senate (1827-41, 1845-50), he  became famous as an orator for his  speeches supporting the Union and  opposing the nullification movement  and its advocates, John C.

While working as a teacher in New  York, he began his lifelong efforts to promote a distinctively American  education. His first step was publishing A Grammatical Institute of the  English Language, including The American Spelling Book (1783), the  famed �Blue-Backed Speller� that went on to sell some 100 million cop�  ies. An ardent Federalist, he founded two pro-Federalist newspapers  (1793) and wrote articles on politics and many other subjects. He pro�  duced his first dictionary in 1806; in 1807 he began work on his landmark  American Dictionary of the English Language (1828; 2nd ed. 1840).  Reflecting his principle that spelling, grammar, and usage should be based  on the living, spoken language, it was instrumental in establishing the  dignity and vitality of American English. In 1821 Webster cofounded  Amherst College.

He wrote plays from 1891, when his trag�  edy The Awakening of Spring created a scandal with its theme of awakening  adolescent sexuality. In his �Lulu� cycle, Earth Spirit (1895) and Pando�  ra �s Box ( 1904), he extended the theme of sex to the underworld of society  and introduced the amoral Lulu.

After  an apprenticeship with his elder brother, he formed a partnership with  another potter and finally went into business for himself. He took a sci�  entific approach to pottery-making and was so successful that the makers  of even Meissen and Sevres porcelain found their trade affected. His many  innovations include development of a green glaze still popular today, the  perfection of creamware, and the invention of the pyrometer.

He formulated the first complete statement of the continental drift hypoth�  esis, which he presented in The Origin of Continents and Oceans (1915).  His theory won some adherents, but by 1930 most geologists had rejected  it because of the implausibility of his postulations for the driving force  behind the continents� movement. It was resurrected in the 1960s as part  of the theory of plate tectonics.

He  studied at the Denishawn school and was a member of its company in the  1920s. In 1928 he cofounded with Doris Humphrey the Humphrey-  Weidman school and dance company, for which he choreographed many  works. His dances, often comic and satiric, employed an abstract, rhyth�  mic pantomime. In 1945 he established his own school, and in 1948 he  founded the Theatre Dance Company, for which he choreographed his  major work, Fables for Our Time.

After  many years of working in isolation, an article in 1854 initiated a string  of important contributions, which he disseminated mainly through lec�  tures. He is known for his work on the theory of functions, and he is called  the father of modem analysis. His greatest influence was felt through his  students, many of whom went on to make important contributions to  mathematics.</p><p>weight Gravitational force of attraction on an object, caused by the  presence of a massive second object, such as the Earth or Moon. It is a  consequence of Isaac Newton�s universal law of gravitation, which states  that the force of attraction between two objects is proportional to the  product of their masses and inversely proportional to the square of the  distance between them. For this reason, objects of greater mass weigh  more on the surface of the Earth. On the other hand, an object�s weight  on the Moon is about one-sixth of its weight on Earth, even though its  mass remains the same, because the Moon has less mass and a smaller  radius than the Earth and therefore exerts less gravitational force. Weight  W is the product of an object�s mass m and the acceleration of gravity g  at the location of the object, or W = mg. Since weight is a measure of  force rather than mass, the units of weight in the International System of  Units are newtons (N). In common usage, weight is measured by the gram  in the metric system and by the ounce and pound in the U.S. and British  systems.</p><p>weight lifting Sport in which barbells are lifted competitively or as an  exercise. The two main events are (1) the snatch, in which the barbell is  lifted from the floor to arm�s length overhead in a single, continuous  motion; and (2) the clean and jerk, in which it is lifted first to the shoulders  and then, after a pause, to arm�s length overhead. Contestants are divided  into 10 body-weight categories ranging from flyweight to superheavy�  weight. Lifts may range to over 1,000 lbs (455 kg) in the heavyweight divi�  sions. The origins of modern competition are to be found in 18th- and 19th-  century strongman contests. The first three Olympic Games (1896, 1900,  1904) included weight lifting, as have all games after 1920.</p><p>weight training System of conditioning involving lifting weights,  especially for strength and endurance.

Aug. 24, 1943,  Ashford, Kent, Eng.) French mystic and social philosopher. After gradu�  ating from the Ecole Normale Superieure, she taught philosophy in sev�  eral girls� schools from 1931 to 1938. To learn the psychological effects  of heavy industrial labour, she took a job in 1934-35 in an auto factory,  where she observed the spiritually deadening effect of machines on her  fellow workers. She assisted the anti-Franco forces in the Spanish Civil War  and aided the French Resistance from London from 1942. Born Jewish,  she converted to Roman Catholicism in the 1940s. She died at age 34 of  tuberculosis complicated by self-imposed starvation undertaken out of  sympathy for those suffering in occupied France. Her posthumously pub�  lished works, including Gravity and Grace (1947), The Need for Roots  (1949), Waiting for God (1950), and Notebooks (3 vol., 1951-56) explore  her own religious life and analyze the individual�s relation to the state  and to God, the spiritual shortcomings of modem industrial society, and  the horrors of totalitarianism.</p><p>Weill \'v!l\, Kurt (Julian) (b. March 2, 1900, Dessau, Ger.�d. April  3, 1950, New York, N.Y., U.S.) German-born U.S. composer. Son of a  cantor, by age 15 he was working as a theatre accompanist. He studied  composition briefly with Engelbert Humperdinck, and a conductor�s post  gave him wide experience. For a master class with Ferruccio Busoni  (1920), he wrote his first symphony. He gained attention with his one-act  opera Der Protagonist (1925); its sparse and spiky style prefigured that  of his greatest works. In 1927 he teamed with Bertolt Brecht to write The  Threepenny Opera (1928) in a new �cabaret� style; the musical had enor�  mous success in Berlin and elsewhere. In 1930 the two produced The Rise  and Fall of the City of Mahagonny. When the Nazis took power in 1933,  he fled to Paris with his wife, Lotte Lenya, where he wrote The Seven  Deadly Sins (1933). In 1935 the couple immigrated to the U.S.; there he  collaborated on musicals such as Knickerbocker Holiday (1938) and Lost  in the Stars (1949). Two of his songs, the �Moritat� (�Mack the Knife�)  from Threepenny Opera and �September Song� from Knickerbocker Holi�  day, have remained especially popular.</p><p>� 2006 Encyclopaedia Britannica,

Government of Germany 1919-33, so  named because the assembly that adopted its constitution met at Weimar  in 1919. In its early years, the Weimar Republic was troubled by postwar  economic and financial problems and political instability, but it had recov�  ered considerably by the late 1920s. Its major political leaders included  presidents Friedrich Ebert (1919-25) and Paul von Hindenburg (1925-34),  as well as Gustav Stresemann, who was chancellor (1923) and foreign  minister (1923-29). With the Great Depression, its political and economic  collapse enabled Adolf Hitler to rise to power and become chancellor  (1933), after which he suspended the Weimar constitution.</p><p>weimaraner ^vl-mo-'ra-nor, 'wl-mo-.ra-norV Dog breed developed in  the early 19th century by German nobles of the court of Weimar. First  used to hunt big game, the breed was later used as a bird dog and retriever.  A graceful dog, it has hanging ears; blue, gray, or amber eyes; and a short,  sleek, mouse- or silver-gray coat. It stands 23-27 in. (58-69 cm) and  weighs 70-85 lbs (32-39 kg). It is characterized by an alert, well-balanced  stance and is valued as an aggressive hunter and a good companion and  watchdog.</p><p>Weingartner VvIn-gart-norV (Paul) Felix, lord von Munzberg</p><p>(b.

After studies in Leipzig,  he came to the attention of Franz Liszt, who arranged the premiere of  Weingartner�s first opera at Weimar (1884). He held conducting posts at  Danzig, Hamburg, and Mannheim, and he became conductor of the Ber�  lin Opera in 1891. He succeeded Gustav Mahler as conductor of the  Vienna Opera (1908-11) and stayed on with the Vienna Philharmonic  until 1927. He also directed the Basel Conservatory (1927-33) and was  a distinguished writer on music.</p><p>Weiser VvI-zorV Johann Conrad (b. Nov. 2, 1696, near Herrenberg,  Wiirttemberg�d.

In  1729 he moved to Pennsylvania, where he worked with the colony�s Indian  agent. He arranged agreements between Iroquois tribes and colonial gov�  ernments that helped form a British-Indian alliance against the French.</p><p>Weisgall, Hugo (David) (b. Oct. 13,1912, Eibenschutz, Moravia�d.  March 11, 1997, Manhasset, N.Y., U.S.) Czech-born U.S. composer. Born  into a musical family that had produced several generations of composers  and cantors, he was raised in Baltimore, Md., U.S., from 1920. He studied  composition with Roger Sessions and conducting with Fritz Reiner, also  earning a doctorate in German literature from Johns Hopkins University.  He is considered one of the most important U.S. opera composers for the  literary quality of his chosen texts and the individuality and effectiveness of  his music; his works include the operas The Tenor (1950), The Stronger  (1952), and Six Characters in Search of an Author (1956); his last com�  pleted opera, Esther (1993), won wide acclaim.</p><p>Weiss \'vls\, Peter (Ulrich) (b.

Weiss painted and  made avant-garde films in the 1950s, then turned to fiction and drama,  establishing a reputation in Germany with his novel Exile (1962). He won  international acclaim for his play The Persecution and Assassination of  Jean -Paul Marat as Performed by the Inmates of the Asylum of Charenton  Under the Direction of the Marquis de Sade (1964; usually referred to as  Marat/Sade), which addressed themes of individualism, revolution, and  violence. Associated with the Theatre of Fact movement, he also wrote the  documentary dramas The Investigation (1965), The Song of the Lusitanian  Bogey (1967), and Discourse on Vietnam (1968).</p><p>Weissmuller Vwis-.mol-oA, Johnny in full Peter John  Weissmuller (b.

He was  reared in Chicago, where he attended the University of Chicago and devel�  oped into a champion swimmer. He won five Olympic gold medals (three  in 1924, two in 1928) and set 67 world records. He later became even  more famous as an actor, starring as Tarzan of the Apes in 12 films  (1932-48) and later creating the role of the comic-book character Jungle  Jim for film and television.</p><p>Weizmann \'vlts-man\, Chaim (Azriel) (b.

After studying in</p><p>Germany and Switzerland, he earned a doctorate in chemistry and pat�  ented several dyestuffs before moving to England to teach in 1904. His  1912 discovery of a bacterium that could convert carbohydrate to acetone  proved of great value to the British armaments industry in World War I  (1914-18), and in return the government aided his negotiations for the  Balfour Declaration (1917). In 1919 he obtained an agreement on Jewish-  Arab coexistence in Palestine from Faysal I, and in 1920 he became presi�  dent of the World Zionist Organization, a post from which he was ousted  in 1931. He settled in Rehovot, Palestine, in 1937. Despite conflicts with  more extreme Zionists, he was sent to the U.S. to secure support for Israel  in 1948, and in 1949 he was elected president.</p><p>Welch, William Henry (b. April 8, 1850, Norfolk, Conn., U.S.�d.  April 30, 1934, Baltimore, Md.) U.S. pathologist. He studied pathology  in Germany before returning to the U.S. to open the nation�s first pathol�  ogy laboratory, at Bellevue Hospital Medical College in New York City  (1879). From 1893 he directed the rise of Johns Hopkins University,  where he developed the country�s first true university department of  pathology. He recruited William Osler and William S. Halsted for the fac�  ulty and was the medical school�s first dean (1893-98). His curriculum  revolutionized U.S. medicine by demanding that students study physical  sciences and be actively involved in clinical duties and laboratory work.  Welch also demonstrated the effects of diphtheria toxin and discovered  bacteria involved in wound fever and gas gangrene.</p><p>Weld, Theodore Dwight (b. Nov. 23, 1803, Hampton, Conn.,  U.S.�d. Feb. 3, 1895, Hyde Park, Mass.) U.S. reformer. He left divinity  studies to become an agent for the American Anti-Slavery Society (1834).  His pamphlets The Bible Against Slavery (1837) and Slavery as It Is  (1839) helped convert figures such as James Birney, Henry Ward Beecher,  and Harriet Beecher Stowe to the antislavery cause. He married his  coworker Angelina Grimke (1838), and they directed schools and taught  in New Jersey and Massachusetts. In 1841�43 Weld organized an anti�  slavery reference bureau in Washington, D.C., to assist congressmen seek�  ing to repeal the gag rule restricting the consideration of antislavery  petitions in Congress.</p><p>welding Technique for joining metallic parts, usually through the appli�  cation of heat. Discovered in the 1st millennium ad during attempts to  manipulate iron into useful shapes, the technique produced a strong, tough  blade. Welding traditionally involved interlayering relatively soft and  tough iron with high-carbon material, followed by hammer forging. Mod�  em welding processes include gas welding, arc welding, and resistance  welding. More recently, electron-beam welding, laser welding, and sev�  eral solid-phase processes such as diffusion bonding, friction welding, and  ultrasonic joining have been developed. See also brazing, soldering.</p><p>Welensky, Sir Roy (b. Jan. 20, 1907, Salisbury, Southern  Rhodesia�&lt;i. Dec. 5, 1991, Blandford Forum, Dorset, Eng.) Rhodesian  politician. He worked on the railways as a youth, later becoming head of  the Railway Workers Union. He held the heavyweight boxing title for  Rhodesia, 1925-27. He began his political career with election to North�  ern Rhodesia�s legislature in 1938. A strong supporter of the Federation  of Rhodesia and Nyasaland (now Zambia, Zimbabwe, and Malawi), he was  elected to its first parliament, became prime minister in 1956, and served  until the federation broke up in 1963.</p><p>Welf dynasty \'velf\ Dynasty of German nobles and rulers. They  descended from Count Welf of Bavaria (early 9th century), whose daugh�  ters married Louis I the Pious and Louis the German. The Welfs were linked  to the House of Este in the 11th century. They supported the papal party  against Emperor Henry IV and were rivals of the Hohenstaufens in central  Europe and in Italy (where their name was Guelpho; see Guelphs and Ghi-  bellines). As part of the House of Hanover, they became rulers of Britain.</p><p>welfare or social welfare Any of a variety of governmental pro�  grams that provide assistance to those in need. Programs include pensions,  disability and unemployment insurance, family allowances, survivor ben�  efits, and national health insurance. The earliest modern welfare laws were  enacted in Germany in the 1880s (see social insurance), and by the 1920s  and �30s most Western countries had adopted similar programs. Most  industrialized countries require firms to insure workers for disability (see  workers' compensation) so that they have income if they are injured,  whether temporarily or permanently. For disability from illness unrelated  to occupational injury, most industrial states pay a short-term benefit fol�  lowed by a long-term pension. Many countries pay a family allowance to  reduce the poverty of large families or to increase the birth rate.

Among the world�s wealthy countries, only the U.S.  fails to provide national health insurance other than for the aged and the  poor (see Medicare and Medicaid).</p><p>welfare economics Branch of economics established in the 20th cen�  tury that seeks to evaluate economic policies in terms of their effects on  the community�s well-being. Early theorists defined welfare as the sum of  the satisfactions accruing to an individual through an economic system.  Believing it was possible to compare the well-being of two or more indi�  viduals, they argued that a poor person would derive more satisfaction  from an increase in income than would a rich person. Later writers argued  that making such comparisons with any precision was impossible. A new  and more limited criterion was later developed: one economic situation  was deemed superior to another if at least one person had been made bet�  ter off without anyone else being made worse off. See also consumer's  surplus; Vilfredo Pareto.</p><p>Welfare Island See Roosevelt Island  Welfare Party See Refah Party</p><p>welfare state Concept of government in which the state plays a key  role in protecting and promoting the economic and social well-being of  its citizens. It is based on the principles of equality of opportunity, equi�  table distribution of wealth, and public responsibility for those who lack  the minimal provisions for a good life. The term may be applied to a vari�  ety of forms of economic and social organization. A basic feature of the  welfare state is social insurance, intended to provide benefits during peri�  ods of greatest need (e.g., old age, illness, unemployment). The welfare state  also usually includes public provision of education, health services, and  housing. Such provisions are less extensive in the U.S. than in many  European countries, where comprehensive health coverage and state-  subsidized university-level education have been common. In countries  with centrally planned economies, the welfare state also covers employ�  ment and administration of consumer prices. Most nations have instituted  at least some of the measures associated with the welfare state; Britain  adopted comprehensive social insurance in 1948, and in the U.S., social-  legislation programs such as the New Deal and the Fair Deal were based  on welfare-state principles. Scandinavian countries provide state aid for  the individual in almost all phases of life.</p><p>Welle, Lawrence (b. March 11, 1903, Strasburg, N.D., U.S.�d. May  17, 1992, Santa Monica, Calif.) U.S. bandleader and television performer.  Born in a German-speaking village in North Dakota, he did not learn  English until he was 21. He played the accordion and formed two musi�  cal groups that opened for bands and orchestras in the Midwest. Welk  moved to Los Angeles, where his television program The Lawrence Welk  Show (1955-71), which featured band music with vocalists, dancers, and  instrumental soloists, became a huge success. The show was dropped by  the network, but Welk continued it as Memories with Lawrence Welk  (1971-82) after he was able to sign contracts with more than 250 inde�  pendent television stations in the U.S. and Canada. Known for his unpre�  tentious warmth and his trademark phrase �Wunnerful, wunnerful,� he  played light, nostalgic �champagne music� and featured smiling perform�  ers such as the Lennon Sisters.</p><p>well-field system Communal land organization supposedly in effect  early in the Zhou dynasty (1046-256 bc). It is mentioned in the writings  of Mencius, who advocated it. In the well-field system, one unit of land  was divided among eight peasant families. A shared field was surrounded  by eight fields, each worked by an individual family. The field in the cen�  tre was worked jointly by the families for their lord. Later reformers  referred to the concept to justify their land-redistribution systems or to  criticize government land practices.</p><p>well-made play French piece bien faite Play constructed accord�  ing to strict technical principles that produce neatness of plot and theat�  rical effectiveness. The form was developed c. 1825 by Eugene Scribe and  became dominant on 19th-century European and U.S. stages. It called for  complex, artificial plotting, a buildup of suspense, a climactic scene in  which all problems are resolved, and a happy ending. Scribe�s hundreds  of successful plays were imitated all over Europe; other practitioners of  the form included playwrights Victorien Sardou, Georges Feydeau, and  Arthur Wing Pinero, who brought the form to the level of art with The  Second Mrs. Tanqueray (1893).</p><p>Weller, Thomas H(uckle) (b.

For  culturing poliomyelitis virus, which led to the development of polio vac�  cines, he shared a 1954 Nobel Prize with John Enders (1879-1985) and  Frederick Robbins (b. 1916). He was the first (with Franklin Neva) to  culture rubella virus and to isolate chickenpox virus from human cell cul�  tures.

In 1861  he was appointed secretary of the navy by Pres. Abraham Lincoln, and in  the American Civil War he built a large Union navy from a few ships,  supported development of the ironclads, and helped form the strategic  naval blockade. His Diary of Gideon Welles (published 1911) contains  valuable insights into the Civil War.</p><p>Welles, (George) Orson (b. May 6, 1915, Kenosha, Wis., U.S.�d.  Oct. 10, 1985, Los Angeles, Calif.) U.S. film director, actor, and producer.  He began acting on stage at 16 and made his Broadway debut in 1934.  He directed an all-African American cast in Macbeth for the Federal The�  atre Project. In 1937 he and John Houseman formed the Mercury Theatre,  creating a series of radio dramas, attempting to mount Marc Blitzstein�s  The Cradle Will Rock in the face of determined opposition, and winning  notoriety with their panic-producing broadcast of War of the Worlds  (1938). Welles then moved to Hollywood, where he cowrote, directed,  produced, and acted in the classic Citizen Kane (1941), noted for its inno�  vative narrative technique and atmospheric cinematography and consid�  ered among the most influential movies in film history. His other films  include The Magnificent Ambersons (1942), The Stranger (1946), The  Lady from Shanghai (1948), Touch of Evil (1958), and Chimes at Mid�  night (1966).

He inherited his father�s Irish title as  earl of Momington and sat in the Irish House of Lords from 1781. He  served in the British House of Commons (1784-97). As governor of  Madras and governor general of Bengal (1797-1805), he used military  force and annexation to greatly enlarge the British Empire in India, but  he was recalled by the East India Co. for his vast expenditures. In 1809  he went to Spain to make diplomatic preparations for the Peninsular War;  he served as foreign secretary (1809-12). As lord lieutenant of Ireland  (1821-28, 1833-34) he tried to reconcile Protestants and Catholics.  Despite his own achievements, he became increasingly jealous of his  younger brother, the duke of Wellington.</p><p>Wellesley College Private women�s college in Wellesley, Mass., char�  tered in 1870.

He acted  in Knickerbocker Buckeroo (1919) with Douglas Fairbanks before turning  to directing. Known as �Wild Bill,� he made the aerial dogfight classic  Wings (1929, Academy Award), setting standards for documentary real�  ism, and he launched a gangster movie trend with Public Enemy (1931),  starring James Cagney. The Ox-Bow Incident (1942), considered one of his  best films, examined frontier justice in the American West. In Track of the  Cat (1954), Wellman experimented with the minimal use of colour. His  other films include A Star Is Born (1937), Nothing Sacred (1937), Beau  Geste (1939), The Story of GI Joe (1945), and The High and the Mighty</p><p>(1954).</p><p>Wells, H(erbert) G(eorge) (b. Sept. 21, 1866, Bromley, Kent,  Eng.�d. Aug. 13, 1946, London) English novelist, journalist, sociologist,  and historian. While studying science under T.H. Huxley in London, Wells  formulated a romantic conception of the subject that would inspire the  inventive and influential science-fiction and fantasy novels for which he  is best known, including the epochal The Time Machine (1895), The Invis�  ible Man (1897), and The War of the Worlds (1898). He simultaneously  took on a public role as an agitator for progressive causes, including the  League of Nations. He later abandoned science fiction and drew on memo�  ries of his lower-middle-class early life in works including the novel  Tono-Bungay (1908) and the comic The History of Mr. Polly (1910). He  had a 10-year affair with the young Rebecca West. World War I shook his  faith in human progress, prompting him to promote popular education  through nonfiction works including The Outline of History (1920). The  Shape of Things to Come (1933) was an antifascist warning. Though a  sense of humour reappears in Experiment in Autobiography (1934), most  of his late works reveal a pessimistic, even bitter outlook.</p><p>Wells, Ida B(ell) or Ida Bell Wells-Barnett (b. July 16, 1862,  Holly Springs, Miss., U.S.�d. March 25, 1931, Chicago, Ill.) U.S. jour�  nalist and antilynching crusader. The daughter of slaves, she was educated  at a freedmen�s school in Holly Springs and later at Fisk University in  Nashville, Tenn. She was a teacher until the late 1880s, when she turned  to journalism, writing articles for African American-owned newspapers  on issues such as the limited education available to African American  children. In 1892, after three of her friends were lynched by a mob, Wells  began an editorial campaign against lynching that quickly led to the  destruction of her newspaper�s office by whites. She continued her anti�  lynching campaign as a lecturer and founder of antilynching societies and  African American women�s clubs throughout the U.S. In 1895 she mar�  ried Ferdinand Barnett and began writing for his newspaper, the Chicago  Conservator. In 1910 she founded the Chicago Negro Fellowship League.  She also founded Chicago�s Alpha Suffrage Club, perhaps the first Afri�  can American woman-suffrage group.</p><p>Wells, Kitty orig.

Her first major hit  was the classic �It Wasn�t God Who Made Honky Tonk Angels� (1952).  Her extensive repertory made her the top-ranking female country artist  for some 15 years, paving the way for later stars such as Patsy Cune and  Loretta Lynn.</p><p>Wells Fargo &amp; Co. Leading U.S. banking and financial services com�  pany formerly involved in express transport. Founded in 1852, Wells,  Fargo transported gold between the west and east coasts in the wake of  the California gold rush. By 1866 it had gained control of almost all  stagecoach business in the West. In 1905 its banking operations were  separated from its express operations. The express carrier disappeared by  the mid 1920s, its domestic business taken over by the firm later known</p><p>as the Railway Express Agency and its foreign express business by Ameri�  can Express Co. Its security services still exist under the name Wells Fargo  Armored Service Corp., a subsidiary of Baker Industries.

The Cardi�  gan Welsh corgi was developed from relatives of the dachshund that Celts  brought to Wales c. 1200 bc. The Pembroke Welsh corgi is descended  from sled-dog stock brought to Wales about 1100 by Flemish weavers.  Both have short legs, a foxlike head, and erect ears, and both stand 10-12  in. (25-30 cm) tall and weigh 25-38 lb (11-17 kg). The Cardigan has a  long tail and rounded ears; the Pembroke has a short tail and pointed ears.  The Cardigan�s coarser coat can be solid-coloured, tricoloured, or  mottled; the Pembroke is solid- or bicoloured.</p><p>Welsh language Celtic ianguage of Wales. Besieged for centuries by  the English language, Welsh continues to be spoken by 18-20% of the  population of Wales, or more than half a million people, though estimates  of the actual number of first-language speakers vary widely. Welsh is tra�  ditionally divided into three periods: Old Welsh (c. 800-1150), attested  mainly in glosses and short textual passages; Middle Welsh (c. 1150�  1500), with a rich medieval literature including poetic texts originally  composed much earlier; and Modem Welsh (from c. 1500). Modern lit�  erary Welsh was largely fixed by William Salesbury�s Bible translation.  Vernacular Welsh, split along dialectal lines, has long been diverging from  literary Welsh; many modern speakers cannot write or easily understand  the traditional written language. The issue of an acceptable modem stan�  dard remains unresolved.</p><p>Welsh literary renaissance Literary activity in Wales and England  in the mid-18th century that attempted to stimulate interest in the Welsh  language and in the classical bardic verse forms of Wales. It was centred  on the Morris family of Welsh scholars, who preserved ancient texts and  encouraged contemporary poets to use the strict metres of the ancient  Welsh bards. The movement gave rise to many publications and helped  reestablish local eisteddfods and, in the early 19th century, the National  Eisteddfod. A second revival began with the establishment of the Uni�  versity of Wales at the end of the 19th century.</p><p>Welly, Eudora (b. April 13, 1909, Jackson, Miss., U.S.�d.

Her main subject is the intricacies of human relationships. She first  gained attention for the story collection A Curtain of Green (1941), con�  taining the widely admired �Petrified Man� and �Why I Live at the PO.�  Other stories appear in The Wide Net (1943), The Golden Apples (1949),  and The Bride of the Innisfallen (1955). Her novels include Delta Wed�  ding (1946), The Ponder Heart (1954), and The Optimist�s Daughter  (1972, Pulitzer Prize).

In 1985 he was named deputy director of  the General Office of the CCP Central Committee and the following year  became director. While at the General Office, Wen also served as chief  of staff to several general secretaries of the CCP, including Zhao Ziyang.  The two men faced criticism after visiting Beijing�s Tiananmen Square  during a series of pro-democracy demonstrations and being photographed  talking with protestors. Although Zhao was placed under house arrest,  Wen escaped any lasting political damage. In 1993 he became a full  member of the Secretariat of the CCP Central Committee and four years  later a member of the Political Bureau. In 1998 he was appointed one of  China�s four vice-premiers.

The son of the emperor Charles IV, he was  a weak ruler whose reign was plagued by wars and princely rivalries. He  spent most of his time in Prague to the detriment of Germany, which suf�  fered a decade of anarchy until peace was established by the Diet at Eger  (1389).

He gained control of Austria and  forced the Austrian estates to accept his son Premysl Otakar II as their  duke in 1251. Bohemia prospered under his reign, and an influx of Ger�  man colonists and craftsmen enriched the country.</p><p>Wenceslas II (b. Sept. 17, 1271�d. June 21, 1305) King of Bohemia  (1278-1305). He inherited the throne from his father at age seven, but his  cousin Otto IV of Brandenburg served as his regent until 1283. Wenceslas  gained full control of the country only after suppressing a dissident fac�  tion and executing his ambitious stepfather in 1290. A capable ruler who  extended the boundaries of his kingdom, he annexed most of Upper Sile�  sia and occupied Krakow (1291). He became king of Poland in 1300 but  declined to become king of Hungary in 1301, instead placing his son  Wenceslas on the Hungarian throne (1301-04).</p><p>Wend Any member of a group of Slavic tribes that by the 5th century  ad had settled in the area between the Oder and Elbe rivers in what is now  eastern Germany. They occupied the eastern borders of the domain of the  Franks and other Germanic peoples. From the 6th century the Franks  warred sporadically against the Wends; under Charlemagne in the early  9th century they began a campaign to subjugate the Wends and forcibly  convert them to Christianity. German annexation of Wendish territories  began in 929 but collapsed during a Wendish rebellion in 983. A German  Crusade against the Wends in 1147, authorized by the church and led by  Henry the Lion, inflicted great loss of life. The Wends thereafter offered  little opposition to German colonization of the Elbe-Oder region; them�  selves enserfed, they were gradually assimilated by the Germans, except  for a minority in the traditional region of Lusatia (in eastern Germany)  who are now known as Sorbs.</p><p>Wenders Wen-dors \, Wim orig.

Yang Jian (b. 541, China�d. 604, China)  Founder of the Chinese Sui dynasty, which reunified China after centuries  of instability. He was born into a powerful family in northern China, an  area controlled by the non-Chinese Northern Zhou dynasty (557-81).  When the Zhou emperor died unexpectedly, Wendi seized the throne,  overcame his rivals, and in 581 proclaimed the Sui dynasty. Intending to  build a strong, centralized state, he designed a huge new capital at  Chang 7 an and attacked entrenched local interests. Families with heredi�  tary local power were replaced with officials selected by examination, who  were forbidden to serve in the areas from which they came and were</p><p>rotated frequently. Wendi conquered the dynasties of southern China and  broke the power of the Turkish empires in Turkistan and Mongolia. He  put the equal-field system into practice and produced a new legal code. His  government brought in tax revenues and maintained price-regulating gra�  naries. In old age he became deeply involved with Buddhism, building  shrines and dedicating relics.

In 1738, inspired  by the theology of Martin Luther, both men had a religious experience that  convinced them that salvation was possible through faith alone. Zealous  evangelists, they had great success in preaching to the masses in the suc�  ceeding decades. In 1784 John began ordaining ministers himself when  the bishop of London refused to do so (despite Charles�s disapproval) and  declared his independence from the Church of England.

Wessex conquered Kent and Sussex, and in the 9th century, under  King Alfred the Great, it prevented the Danes from conquering England  south of the Danelaw. By 927 Wessex had reconquered the Danelaw, and  Alfred�s grandson, Athelstan, had become king of all England; thereafter  all kings of Wessex were kings of England. The region figures promi�  nently in legends of King Arthur (see Arthurian legend), and the designa�  tion �Wessex� was used by Thomas Hardy to represent the region of  southwestern England in which he set his works of fiction.</p><p>West, Benjamin (b.

After studying painting in  his native Philadelphia, he established himself as a portraitist in New York  City. He sailed to Italy in 1760 and visited most of its art centres before  settling in London in 1763. The patronage of George III freed him of the  need to paint portraits for a living, and he became known for historical,  religious, and mythological subjects. His Death of General Wolfe (1771)  aroused controversy for its depiction of modem dress rather than the  flowing robes expected in a history painting, but it was one of his most  popular works. He never returned to the U.S., but through such pupils and  followers as Washington Allston, Gilbert Stuart, Charles Willson Peale,  and John Singleton Copley he exerted considerable influence on the devel�  opment of U.S. art in the 19th century.</p><p>West, Jerry in full Jerome Alan West (b.

Her admired reports on the NOrnberg trials were collected in A  Train of Powder (1955). Her history of Yugoslavia, Black Lamb and Grey  Falcon (1942), is regarded as one of the century�s finest nonfiction works.  In 1946 she reported on the trial for treason of William Joyce, articles that  were later published as The Meaning of Treason (1949).</p><p>West Atlantic languages See Atlantic languages</p><p>West Bank Area (pop., 2002 est.: 2,414,000), Palestine, west of the Jor�  dan River and east of Jerusalem. Covering an area of about 2,270 sq mi  (5,900 sq km), excluding east Jerusalem, the territory is also known within  Israel by its biblical names, Judaea and Samaria. It is a region with deep  history, forming the heart of historic Palestine. Populated areas include  Nabulus, Hebron, Bethlehem, and Jericho. Under a 1947 UN agreement,  most of what is now the West Bank was to become part of a Palestinian  state. When the State of Israel was formed, the Arabs attacked Israel (see  Arab-Israeu wars), and the partition plan was never adopted. Following a  truce, Jordan remained in control of the area and annexed it in 1950. Israel  subsequently occupied it during the Six- Day War of 1967. During the  1970s and �80s Israel established settlements there, provoking resentment  among the Arab population and protest from the international community.  Arab uprisings began in 1987 in the Gaza Strip and spread to the West  Bank (see intifadah). Jordan relinquished its claims in 1988, ceding them  to the Palestine Liberation Organization (PLO). Secret meetings between  the PLO and Israel in 1993 led to an end of violence and an agreement  granting Palestinian self-rule in parts of the West Bank and Gaza Strip.  Further negotiations to resolve outstanding issues proceeded intermit�  tently in the 1990s but broke down amid renewed violence in late 2000.</p><p>West Bengal State (pop., 2001 prelim.: 80,221,171), northeastern  India. It is bordered by Nepal and Bangladesh and the states of Orissa,  Jharkhand, Bihar, Sikkim, Assam, and Meghalaya and has an area of 34,267  sq mi (88,752 sq km); the capital is Kolkata (Calcutta). It encompasses  two broad natural regions, the Gangetic Plain in the south and the Hima�  layas in the north. From the 3rd century bc it formed part of Ashoka�s  empire. In the 4th century ad it was absorbed into the Gupta empire. From  the 13th century it was under Muslim rule, until it came under the Brit�  ish in 1757. At Indian independence in 1947, it was partitioned, with the  eastern sector becoming East Pakistan (later Bangladesh) and the west�  ern sector becoming India�s West Bengal. The state is important for its  mineral output, but agriculture is its main economic activity. It is noted  for its artistic endeavours, including filmmaking.</p><p>West Florida Controversy Dispute over status of American terri�  tory in a region on the Gulf of Mexico between the Apalachicola and  Mississippi rivers. First claimed by Spain in 1492, it was occupied by  France as part of Louisiana after 1695, then passed under various treaties  to Britain (1763) and Spain (1783). The U.S. claimed it as part of the  Louisiana Purchase (1803), and American frontiersmen rebelled against  Spanish control in 1810. Under the Transcontinental Treaty of 1819, Spain  ceded all claim to West Florida, and it became part of the U.S. in 1821.</p><p>West Indies Islands, enclosing the Caribbean Sea.

Its main centre is Birmingham. From 1974 to 1986 West  Midlands was an administrative metropolitan county; in 1986 its admin�  istrative functions were dispersed, and it is now a geographic and cer�  emonial county without administrative authority. Early settlement was  sparse until Saxon colonists arrived; Coventry was the region�s only sig�  nificant town by the late 14th century. Small metalworking industries  began in Birmingham in the 16th century, and by the 18th century the  area�s coalfields were important for ironworking. Many of the West Mid�  lands� traditional metallurgical and manufacturing industries persisted  into the 21st century, alongside the growth of electrical engineering and  the manufacture of motor vehicles, aircraft, and synthetic fibres. The West  Midlands name is also applied to the western portions of the Midlands  region comprising Staffordshire, Warwickshire, Shropshire, Herefordshire,  and Worcestershire; this combined area constitutes one of England�s  so-called standard regions.</p><p>West Nile virus Virus, belonging to the family Flaviviridae, that can  cause encephalitis (inflammation of the brain). West Nile is predominantly  a fatal infection of birds but can be transmitted to humans by mosquitoes.  Most human infections are inapparent or mild, causing a flu-like illness  that lasts only a few days. A minority develop encephalitis, characterized  by headache, fever, neck stiffness, and muscle weakness, that has proved  fatal in some cases. There is no cure. In severe cases, intensive medical  care, involving intravenous fluids and respiratory support, is necessary.  The virus was originally confined to Africa, the Middle East, and South�  east Asia but has spread to Europe and North America.</p><p>West Point See United States Military Academy  West River See Xi River</p><p>West Sussex Administrative county (pop., 2001: 753,612), southeast�  ern England. It borders the English Channel, and its administrative centre  is Chichester. There is evidence of settlements dating from prehistoric  times in the region. A dynasty of British chieftains was in the area just  before the Roman invasion. After the Romans left, Saxon invaders con�  quered Sussex in the late 5th century. They were overcome by the peoples  of neighbouring Wessex and later by the Normans, who built castles and  monasteries. Since the beginning of the 14th century, the growth of sea�  side resorts has been important in the development of the area�s coast;  inland, much of it remains rural.</p><p>West Virginia State (pop., 2000: 1,808,344), east-central U.S. It cov�  ers an area of 24,232 sq mi (62,760 sq km); its capital is Charleston. West  Virginia is bordered by Pennsylvania to the north, Maryland and Virginia  to the east, Kentucky to the southwest, and Ohio to the northwest. The  Ohio River forms a large section of the upper western boundary, while the  Potomac River forms a section of the northern boundary. The Great  Kanawha, Little Kanawha, Monongahela, and Shenandoah rivers cross  the state. West Virginia is crossed by the Appalachian Mountains and is  generally rugged land. The highest elevation is Spruce Knob (4,861 ft  [1,482 m]). Long occupied by Indian hunters, it was home to the Adena,  or Mound Builders, who left archaeological traces. They were succeeded  by the Iroquois and the Cherokee. The first permanent white settlement  was in the 1730s. The English controlled the region during the 1750s and  1760s. Though eastern Virginia was rapidly settled, the western area�s  rugged terrain restricted settlement there. After the American Revolution,  largely nonslaving settlers moved west; they grew dissatisfied with the  Virginia government. With the outbreak of the American Civil War, resi�  dents from western Virginia voted against the ordinance of secession in  1861. In 1863 West Virginia was admitted to the Union as the 35th state.  Its industrial emergence, encouraged by railroad expansion, began in the  1870s when its natural resources, including coal and gas, contributed to  the growth of the U.S. In the 20th century, recreation and tourism became  an increasingly important part of the state�s economy.</p><p>West Yorkshire Metropolitan county (pop., 2001: 2,079,217), north�  ern England. Its main cities are Wakefield and Leeds. From 1974 to 1986  West Yorkshire was an administrative unit; in 1986 the metropolitan</p><p>county lost its administrative powers, and its constituent boroughs became  autonomous unitary authorities. Anglo-Saxons and Scandinavians from  the east established the first settlements. While baronial power was strong  in the medieval period, anarchic conditions often prevailed, and the area  was the site of several 15th-century battles. In the same period, the wool  textile industry developed. In the 18th and 19th centuries, abundant water�  power, and later steam power based on locally mined coal, stimulated  factory-based industry. Worsted and woolen industries remain important,  while an engineering industry has developed. Leeds, the area�s largest  city, is a major commercial and cultural centre.</p><p>western Genre of novels and short stories, motion pictures, and televi�  sion and radio shows set in the American West, usually during 1850-1900,  when the area was opened to white settlement. Though basically an Ameri�  can creation, it has counterparts in the gaucho literature of Argentina and in  tales of the settlement of the Australian Outback. Conflicts between white  pioneers and Native Americans and between cattle ranchers and fence�  building farmers form two basic themes. Cowboys, the town sheriff, and  the U.S. marshal are staple figures, and lawlessness and gun violence are  standard. Owen Wister�s The Virginian (1902) is regarded as the seminal  western novel; the popularity of the genre peaked in the early and middle  decades of the 20th century and declined somewhat thereafter.</p><p>Western Australia State (pop., 2001: 1,906,114), western Australia.  Covering 976,790 sq mi (2,529,880 sq km), it constitutes one-third of the  continent�s area but has less than one-tenth of Australia�s population; its  capital is Perth. The extensive interior region has three deserts: Great  Sandy, Gibson, and Great Victoria. The coast along the Timor Sea and  Indian Ocean has only a few good harbours; notable inlets are Joseph  Bonaparte and Exmouth gulfs. Australian Aboriginal peoples have occu�  pied Western Australia for about 40,000 years. The western coast was first  visited in 1616 by the Dutch; it was later explored by Englishman Wil�  liam Dampier in 1688 and 1699. In 1829 Capt. James Stirling led the first  group of settlers there to establish Australia�s first nonconvict colony. The  discovery of gold in 1886 prompted a movement for constitutional  autonomy, which was granted in 1890. In 1900 it was the last state to  ratify the newly constituted Commonwealth of Australia. Initially it suf�  fered from slow growth, but since 1960 its economy, fueled by agricul�  ture and mining (notably of hydrocarbons), has been expanding.</p><p>Western Dvina River Russian Zapadnaya Vza-pod-no-yoV  Dvina Latvian Daugava Vdau-g3-v3\ River, north-central Europe. It  rises in Russia�s Valdai Hills and flows 632 mi (1,020 km) in a great arc  south through Russia and into Belarus and then northwest across Latvia.  It discharges into the Gulf of Riga on the Baltic Sea. An important water  route since early times, connected in its upper reaches by easy portages  to the Dnieper, Volga, and Lovat-Volkhov river systems, it constituted part  of the great trade route from the Baltic region to Byzantium and to the  Arabic east. Rapids and the presence of dams have restricted navigation  on it.</p><p>Western Electric Co. Inc. Former U.S. telecommunications company.  Founded in 1869 by Elisha Gray and Enos N. Barton, the firm was incor�  porated in Chicago, Ill., in 1872 as the Western Electric Manufacturing  Co. It manufactured a series of new products, including the world�s first  commercial typewriters and incandescent lamps. Bell Telephone bought  a controlling interest in the company in 1881; the next year it was rein�  corporated as Western Electric Co., becoming part of the Bell System (see  AT&amp;T Inc.). It became a major manufacturer of telephone equipment and  communications satellites, in addition to producing radar and missile sys�  tems. In 1983, with the breakup of AT&amp;T, the company was dissolved as  a separate subsidiary and became part of AT&amp;T Technologies (renamed  Lucent Technologies).</p><p>Western European Union (WEU) Association of 10 European  countries to coordinate matters of European security and defense.

Population (2002 est.):  256,000. Capital: Laayoune. Little is known of the area�s prehistory,  though rock engravings in southern locations suggest a succession of  nomadic groups. In the 4th century bc there was trade across the Medi�  terranean Sea between the region and Europe; this did not last, and there  was little European contact until the 19th century. In 1884 Spain claimed  a protectorate over the Rio de Oro region. Boundary agreements with  France were concluded in 1900 and 1912. Spain formally united the area�s  northern and southern parts into the overseas province of the Spanish  Sahara in 1958. In 1976 Spain relinquished its claim. The region then was  divided between Mauritania, which relinquished its claim in 1979, and  Morocco, which later occupied the whole territory. Separatists of the  Polisario movement, based in Algeria, declared a government-in-exile  called the Saharan Arab Democratic Republic in 1976; the issue of West�  ern Sahara�s status remained unresolved, remained unresolved.Western  Sahara has vast phosphate deposits and some potash and iron ore.</p><p>Western Samoa See Samoa</p><p>Western Scheldt or Westerschelde Vves-tor-.skel-doN Estuary,  southwestern Netherlands.

From its foundation in 1851  as a company formed to build a telegraph line from Buffalo, N.Y., to St.  Louis, Mo., in 1856 the expanding business was reorganized as the West�  ern Union Telegraph Co. By the end of 1861 Western Union had built the  first transcontinental telegraph line. The company introduced singing tele�  grams in 1933. Western Union continued to grow, absorbing competitors  such as Postal Telegraph Inc. in 1943. As telegraphy was superseded by  other methods of telecommunication, Western Union diversified into tele�  typewriter services, money orders, and mailgrams. It launched the tele�</p><p>communications satellite Westar 1 in 1974 and was operating five  satellites by 1982. In 1988 the company was reorganized as Western  Union Corp. to handle money transfers and related services. After declar�  ing bankruptcy in 1993, it sold its financial services arm in 1994 to First  Financial Management Corp., and in 1995 that company merged with First  Data Corp.

U.S. inventor and industrialist.</p><p>He served in the American Civil War.</p><p>His first major invention was an air  brake (patented 1869), which was  eventually made compulsory on all  American trains. He developed a  railway signaling system and later  introduced many innovations in pip�  ing natural gas. His major achieve�  ment was the adoption by the U.S. of  alternating current (AC) for electric  power transmission. The electrical  system being developed in the U.S.  in the 1880s used direct current (DC),  though AC systems were being  developed in Europe. Westinghouse  purchased the patents for Nikola Tes�  la�s AC motor and hired Tesla to  improve and modify the motor for  use in his power system. In 1886 he  incorporated the predecessor of Westinghouse Electric Corp. He eventu�  ally prevailed over powerful opposition from advocates of DC power, and  in 1893 his company was hired to light the World�s Columbian Exposi�  tion at Chicago. He also obtained the rights to develop the great falls of  the Niagara River with AC generators. See also electric current.</p><p>Westinghouse Electric Corp. U.S. television and radio broadcast�  ing company, formerly an electrical equipment manufacturer. It was  founded in 1886 as the Westinghouse Electric Co. by George Westing�  house to make and sell alternating-current electrical systems. The com�  pany became a major supplier to the electric-utility industry, producing  machinery used to generate and distribute electricity. It adopted the name  Westinghouse Electric Corp. in 1945. After World War II Westinghouse  also manufactured nuclear reactors and defense electronics. In the 1990s  it bought television and radio stations throughout the U.S., including the  television network CBS Inc. in 1995 and Infinity Broadcasting Corp. in  1996. After selling its defense electronics unit to Northrop Grumman  Corp. in 1996, the company changed its name to CBS Corp. in 1997 and  sold its nuclear operations to British Nuclear Fuels PLC in 1998.

A camera enthusiast  from boyhood, Weston began his  professional career by opening a por�  trait studio in Glendale, Calif. His  early work was in the style of the  Pictorialists, photographers who imi�  tated Impressionist paintings. In 1915  Weston saw an exhibition of modern  art that inspired him to renounce his  former work: he began to create  sharp and realistic pictures that con�  vey the beauty of natural objects  through skillful composition and  subtleties of tone, light, and texture.</p><p>After traveling and meeting luminar�  ies such as Alfred Stieglitz and Diego  Rivera, in 1927 Weston made a series  of monumental close-ups of sea-  shells, peppers, and halved cabbages,  bringing out the rich textures of their  sculpturelike forms. Two years later he made the first of many photo�  graphs of the rocks and trees on Point Lobos, Calif. In 1936 Weston began  a series of photographs of nudes and sand dunes at Oceano, Calif., which  are often considered his finest work. After being stricken by Parkinson  disease, Weston realized he would soon be unable to work. He made his  last photographs on Point Lobos in 1948. He is considered one of the  most influential photographers of the 20th century.</p><p>Westphalia Former province of Prussia, now part of Germany. It com�  prises (with the former state of Lippe) the present German state of North  Rhine-Westphalia and parts of the states of Lower Saxony and Hesse.  Settled by Saxons called Westphalians c. ad 700, Westphalia was created  a duchy (1180), which for several centuries was administered for the  archbishop of Cologne. The Peace of Westphalia (1648) was signed at  Monster. In 1807 Napoleon created for his brother, Jerome Bonaparte, the  kingdom of Westphalia; its capital was Kassel. Reorganized by the Con�  gress of Vienna in 1815, it became a province of Prussia in 1816, with its  capital at Munster. Its cities suffered severe bombings in World War II.</p><p>Westphalia, Peace of (1648) European settlements that ended the  Thirty Years' War, negotiated in the Westphalian towns of Munster and  Osnabriick. The deliberations began in 1644 and ended in 1648 with two  assemblies that produced the treaty between Spain and the Dutch (signed  January 30) and another between Emperor Ferdinand III, the other German  princes, France, and Sweden (signed October 24). Territorial changes gave  Sweden control of the Baltic Sea, ensured France a firm frontier west of  the Rhine River, and provided their allies with additional lands. Indepen�  dence was confirmed for the United Provinces of the Netherlands and for  the Swiss Confederation. The treaties also confirmed the Peace of Augs�  burg and extended the religious toleration of Lutherans to include tolera�</p><p>tion of the Reformed (Calvinist) Church.

In early paintings he combined Camp-  in�s bold style with the elegance and subtle visual refinements he admired  in the art of Jan van Eyck. By 1435 he moved to Brussels and the next  year was appointed city painter. During that period (c. 1435�40) he  executed the celebrated panel of the Descent from the Cross for the chapel  of the Archers� Guild of Louvain. His international reputation grew, his  work being particularly admired in Italy. Though most of his work was  religious, he produced secular paintings (now lost) and some sensitive  portraits.

He  immigrated to the U.S. at age 18 and found work in an Illinois sawmill,  which he and his brother-in-law bought in 1857. He traveled constantly  to buy stands of timber and acquired an interest in many logging and  milling operations. In 1872 he organized the Mississippi River Boom and  Logging Co., a huge confederation that handled all the logs milled on the  Mississippi. In 1900 he bought 900,000 acres of timberland in the Pacific  Northwest and founded the Weyerhaeuser Timber Co. (now Weyerhaeu�  ser Co.), centred in Tacoma, Wash.

More than  10 mi (16 km) wide in 1911, it gradually narrowed as advancing ice sheets  collided. It disappeared entirely in 1987 when an iceberg 99 mi (159 km)  long broke off from the Ross Ice Shelf.</p><p>whaling Hunting of whales for food, oil, or both. Whaling dates to pre�  historic times, when Arctic peoples used stone tools to hunt whales. They  used the entire animal, a feat not accomplished by Western commercial  whalers until the advent of floating factories in the 20th century. The  Basque were the first Europeans to hunt whales commercially; when sea�  worthy oceangoing vessels began to be made, they took to the open seas</p><p>Edward Weston at Point Lobos, Carmel  Bay, Calif., 1945</p><p>IMOGEN CUNNINGHAM</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Wharton &#x25BA; Whig Party i 2051</p><p>(14th�16th century). They were followed by the Dutch and the Germans  in the 17th century and the British and their colonists in the 18th century.  In 1712 the first sperm whale was killed; its oil proved more valuable than  that of the right whale, which had hitherto been the object of whaling ven�  tures. Whaling expeditions in pursuit of the free-ranging sperm whale  could last for four years. The discovery of petroleum (1859), overfishing,  the use of vegetable oil, and the substitution of steel for whalebones in  corsets led to a steep decline in whaling in the later 19th century, but Nor�  wegian innovations made hunting the hitherto �wrong� whales (rorquals,  including the blue whale and the sei whale; so called because they sank  when killed) commercially feasible, and the number of whales killed rose  from under 2,000 to over 20,000 between 1900 and 1911. The Norwe�  gians and the British dominated whaling into the mid 20th century, when  overfishing again made it unprofitable for most nations, though not Japan  and the Soviet Union, which became the chief whaling nations. Concern  over the near extinction of many species led to the establishment in 1946  of the International Whaling Commission. Commercial whaling was pro�  hibited altogether in 1986, but several nations refused to comply. At the  beginning of the 21st century, Norway and Japan continued to hunt hun�  dreds of nonendangered whales annually.</p><p>Wharton, Edith (Newbold) orig. Edith Newbold Jones (b.</p><p>Jan. 24, 1862, New York, N.Y., U.S.�d. Aug. 11, 1937, Saint-Brice-sous-  Foret, near Paris, France) U.S. novelist and short-story writer. Born into  upper-class society, she began writing a few years after her marriage in  1885. She lived in France after 1908 and was divorced in 1913. Her works  examine the barriers of social convention, especially in the upper class,  that stand in the way of individual happiness. Her close friendship with  the older novelist Henry James did much to support and shape her work.  The critical and popular success of her novel The House of Mirth (1905;  film, 1918, 2000; for television, 1981) established her as a leading writer.  She is perhaps best known for Ethan Frome (1911), which exploits the  grimmer possibilities of New England farm life. Her other books include  the novels The Custom of the Country (1913), The Age of Innocence  (1920, Pulitzer Prize), and The Buccaneers (1938).</p><p>wheat Any of various cereal grasses in the genus Triticum of the Poaceae  (or Gramineae) family, one of the oldest and most important of the cereal  crops. More of the world�s farmland is devoted to wheat than to any other  food crop; China is the largest wheat producer. The plant has long, slen�  der leaves, hollow stems in most varieties, and flowers grouped together  in spikelets. Of the thousands of varieties known, the most important are  T. aestivum, used to make bread; T. durum , used in making pasta; and T.  compactum (club wheat), a softer type used for cake, crackers, cookies,  pastries, and household flours. Winter wheat (sown in fall) and spring  wheat (sown in spring or, where winters are mild, sometimes fall) are the  two major types. The greatest portion of wheat flour is used for bread�  making. Small quantities are used in the production of starch, malt, glu�  ten, alcohol, and other products. Inferior and surplus wheats and various  milling by-products are used for livestock feeds.</p><p>Wheatley, Phillis (b. c. 1753, present-day Senegal or The Gambia?,  West Africa�d. Dec. 5, 1784, Boston, Mass., U.S.) African American  poet and the first African American to publish a book. She was kidnapped,  transported to America, and sold from a slave ship in 1761 to John Wheat-  ley, a Boston merchant. The Wheatleys taught her to read and write  English and Latin. At about age 14 she began writing poetry modeled on  Alexander Pope and other Neoclassical writers. Her verse�exceptionally  mature, if conventional, poetry that was largely concerned with morality  and piety�attracted much attention. Poems on Various Subjects, Reli�  gious and Moral (1773), published in England, spread her fame to Europe.  Freed in 1773, she married a free black man in 1778. She worked as a  servant in her final years and died in poverty.</p><p>wheel Circular frame of hard material capable of turning on an axle.  Wheels may be solid, partly solid, or spoked. The oldest known wheel  was a wooden disk of planks held together by crosspieces. A pottery wheel  or turntable was developed c. 3500 bc in Mesopotamia. The spoked wheel  appeared c. 2000 bc on chariots in Asia Minor. Later developments  included iron hubs that turned on greased axles. Perhaps the most impor�  tant invention in human history, the wheel was essential to developing  civilizations, and has remained essential to power generation, transporta�  tion, industrial manufacturing, and countless other applications.</p><p>wheel lock Device for igniting the powder in a firearm such as a mus�  ket. Developed c. 1515, the wheel lock struck a spark to ignite powder in</p><p>the pan of a musket by means of a holder that pressed a shard of flint or  a piece of iron pyrite against an iron wheel with a milled edge; the wheel  rotated and sparks flew. The principle was used in the design of the flint-  and-wheel cigarette lighter.

The  sturdy shell of most species in the  family is slender and has a wide  opening in the first whorl. The ani�  mal feeds on other mollusks through  its long proboscis; some species also  kill fishes and crustaceans caught in  commercial traps. Most are cold-  water species; tropical species are  smaller and more colourful. The  common northern whelk ( Buccinum  undatum ) has a stout pale shell about  3 in. (8 cm) long and is abundant in North Atlantic waters.</p><p>Whewell Vhyu-oL, William (b. May 24, 1794, Lancaster, Lanca�  shire, Eng.�d. March 6, 1866, Cam�  bridge, Cambridgeshire) British  philosopher and historian. He spent  most of his career at the University  of Cambridge, where he taught min�  eralogy (1828-32) and moral phi�  losophy (1838-55) and served as  college master (1841-66). He is  remembered primarily for his work  on the theory of induction. He  stressed the need to see scientific  progress as a historical process,  asserting that inductive reasoning  could be employed properly only if  its use throughout history was  closely analyzed. His major works  on induction are History of the  Inductive Sciences (3 vol., 1837) and  Philosophy of the Inductive Sciences  (1840).

Originally a term for Scot�  tish Presbyterians, the name came to  imply nonconformity and rebellion and was applied in 1679 to those who  wanted to exclude James, the Catholic duke of York (later James II), from  succession to the throne of England. The Whigs were opposed by the Tory  faction in that struggle but later represented the aristocratic, landowning  families and financial interests of the wealthy middle classes. They main�  tained power through patronage and connections in Parliament, but there  was no distinct party until 1784, when Charles James Fox represented the  interests of religious dissenters, industrialists, and others who sought par�  liamentary reform. After 1815 and following various party realignments,  the political group became the Liberal Party.</p><p>Whig Party (1834-54) U.S. political party. Organized by opponents of  Pres. Andrew Jackson, whom they called �King Andrew,� the party took  its name from the British antimonarchist party. The U.S. Whigs favoured  a program of national development. Jackson�s opposition to the Second  Bank of the United States (see Bank War) and nullification in South Caro�  lina allowed Henry Clay to bring fiscal conservatives and southern states'  rights proponents together in a coalition with those who still believed in  the National Republican program of a protective tariff and federally  financed internal improvements. The party also included members of the  former Anti-Masonic Party. The Whig�s candidate, William H. Harrison,  won the 1840 presidential election and the party captured Congress, but  Harrison�s premature death halted enactment of the Whig program (his  vice president and successor, John Tyler, vetoed much of the Whig�s  agenda). Clay was the party�s unsuccessful candidate in the 1844 elec�  tion. In 1848 it nominated Zachary Taylor, who won the presidency. The  party began to split into the �conscience� (antislavery) and �cotton� (pro�  slavery) Whigs and was further divided by the Compromise of 1 850.

He studied  medicine at Johns Hopkins Univer�  sity. He and George Minot discov�  ered that raw liver fed to chronically bled dogs reversed anemia; this led  to introduction of raw liver in the diet to treat pernicious anemia, for which  the two men shared a 1934 Nobel Prize with William Murphy (1894-  1987). Whipple�s study of bile pigments led to an interest in how the body  makes hemoglobin (important in bile pigment production). His experi�  ments in artificial anemia (1923-25) established iron as the most potent  inorganic factor in red-blood-cell formation.</p><p>whippoorwill Species ( Caprimulgus vociferus ) of nocturnal North  American bird, similar to the nightjar, named for its resonant �whip-poor-  will� call (first and third syllables accented), which it may repeat 400  times without stopping. It lives in woods near open country, where it  catches insects on the wing around dusk and dawn. By day it sleeps on  the forest floor or perches lengthwise on a branch. About 10 in. (25 cm)  long, it has mottled brownish plumage; the male has a white collar and  white tail comers. It winters as far south as Costa Rica.</p><p>whiskey or whisky Any of several distilled liquors made from a fer�  mented mash of cereal grains. Whiskeys are distinctive because of differ�  ences in raw materials and production methods. All are aged in wooden  containers. The earliest direct account of whiskey making is found in  Scottish records from 1494. Scotch whisky (this spelling is also used by  Canadians) is usually somewhat light in body, with a distinctive smoky  malt flavour; it is made primarily from malted barley that has been heated  over a peat fire, fermented, distilled, and blended with similar whiskies  made by different distillers. Irish whiskeys, lighter-bodied and lacking any  smoky flavor, are not malt-fired and may be mixed with neutral grain  spirits. Canadian whisky, light in colour and flavour, is a blend of highly  flavoured and neutral grain whiskies. In the U.S., the largest producer and  consumer of whiskey, both straight (at least 51% single-mash) and  blended whiskeys are produced, derived from both sour and sweet  mashes. (Sour mashes are fermented with both fresh and previously fer�  mented yeast; sweet mashes employ only fresh yeast.) Bourbon, first pro�  duced in Bourbon Co., Ky., is a full-bodied unblended whiskey derived  from a sour mash of corn grain. Whiskeys are consumed both unmixed  and in cocktails, punches, and other beverages.</p><p>Whiskey Rebellion (1794) American uprising to protest a federal  liquor tax. Farmers in western Pennsylvania rebelled against paying a tax  on their locally distilled whiskey and attacked federal revenue collectors.  After 500 armed men burned the home of the regional tax inspector, Pres.  George Washington ordered 13,000 federal troops to the area. The rebel�  lion quickly dissolved without further violence. The event established the  authority of federal law within the states and strengthened support for the  Federalists� advocacy of a strong central government.</p><p>Whiskey Ring (1875) Group of U.S. whiskey distillers who defrauded  the government of taxes. The ring operated mainly in St. Louis, Milwau�  kee, and Chicago and kept liquor taxes after bribing Internal Revenue  officials in Washington, D.C. A secret investigation by the U.S. Treasury  Department resulted in 238 indictments and 110 convictions. While not  involved, Pres. Ulysses S. Grant was tarnished by the scandal; his private</p><p>secretary, Orville E. Babcock, was indicted but acquitted on Grant�s tes�  timony. The Republican Party allegedly received some of the illegally  held tax money.</p><p>whist 1 Card game. It belongs to a family that includes bridge whist and  bridge, each of which developed in succession from the original game of  whist. The essential features of card games in the whist family are: four  people usually play, two against two as partners; a full 52-card deck is dealt  out evenly so that each player holds 13 cards; the object of play is to win  tricks, and win or loss is determined by the number of tricks taken (as dis�  tinct from games such as pinochle, in which it is determined by the value of  card points taken in tricks). Whist originated in 17th-century England.</p><p>whistler See goldeneye</p><p>Whistler, James (Abbott) McNeill (b. July 14, 1834, Lowell,  Mass., U.S.�d. July 17, 1903, London, Eng.) U.S.-born British painter,  etcher, and lithographer. He attended West Point but soon abandoned the  army for art. In 1855 he arrived in Paris to study painting and adopted a  bohemian lifestyle. In 1863 he moved to London, where he had consid�  erable success, becoming widely famous for his wit and large public pres�  ence. During the 1860s and �70s he began to use musical terms in the  titles of his paintings, such as Symphony and Harmony, reflecting his  belief in the �correspondences� between the arts. During this period he  started to paint his �nocturnes��scenes of London, especially of Chelsea,  that have poetic intensity. For them he evolved a special technique by  which paint, in a very liquid state he called a sauce, was stroked onto the  canvas in fast sweeps of the brush, somewhat in the manner of Japanese  calligraphy (he was an outspoken advocate of Japanese arts). From the  1870s onward he was preoccupied by the problems of portrait painting,  creating a number of masterpieces, including Arrangement in Grey and  Black, No. 1: The Artist�s Mother (1871-72), known as Whistler�s Mother.  These paintings underline his aestheticism, his liking for simple forms  and muted tones, and his dependence on the 17th-century Spanish painter  Diego VelAzquez. In 1877 he brought a libel suit against John Ruskin for  attacking his Nocturne in Black and Gold: The Falling Rocket (1875); he  won his case but received damages of only a farthing, and the costs of  the suit temporarily bankrupted him. Considered one of the leading paint�  ers of his day, after his death his reputation declined. Only in the later  20th century did Whistler begin to receive serious acclaim once again.</p><p>whistling swan Species ( Cygnus columbianus) of North American  swan that calls with a soft, musical note.

Though  Northumbria had been mainly converted by Celtic missionaries, the king  decided for Rome, believing that Rome followed the teaching of St. Peter,  holder of the keys to heaven. The decision contributed to the unification  of the English church and brought it into close contact with the rest of  Europe.</p><p>White, Byron R(aymond) (b.

Cofounders of the Seventh-Day Adventists. James  was a schoolteacher and then a minister who accepted the Adventist views  of William Miller (1782-1849). He married Ellen Harmon in 1846; she  had become a Millerite in 1840, at 13. A visionary, Ellen had more than  2,000 visions before she died; these helped guide the Seventh-Day Adven�  tist Church, which was formed in 1863. They preached together until  James�s death.

He sailed on an expedition to Greenland in 1577 and returned  to England with sketches of the land and its people. His 1585 trip to colo�  nize Roanoke was sponsored by Sir Walter Raleigh. White�s paintings and  sketches illustrated a report of the region after the colony was abandoned  (1586). He was appointed governor of a second colony and arrived at  Roanoke with 100 colonists (1587). He returned to England for supplies  that year but was unable to send a relief expedition to Roanoke until 1590;  the expedition found no trace of the colonists, including White�s grand�  daughter, Virginia Dare.</p><p>White, Minor (b.

In 1946 he studied with Edward Weston and Alfred Stieg-  litz before moving to San Francisco, where he worked closely with Ansel  Adams. He succeeded Adams as head of the photography department at  the California School of Fine Arts and later taught at MIT. He founded  and edited (1952-76) the photography magazine Aperture and also edited  Image (1953-57).

After serving in the Royal Air Force during World  War II, he returned to Australia, which he saw as a country in a volatile  process of growth and self-definition. His somewhat misanthropic novels  often explore the possibilities of savagery in that context; they include  The Tree of Man (1955), Voss (1957), Riders in the Chariot (1961), and  The Twyborn Affair (1979). His other works include plays and short sto�  ries, the latter collected in The Burnt Ones (1964) and The Cockatoos  (1974).

Mead that soon became the most famous in the country, known  especially for its Shingle-style country and seaside mansions. The firm  later led the U.S. trend toward Neoclassical architecture. White�s design  for the Casino (1881) at Newport, R.I., exhibited his characteristic use of  gracefully proportioned structures and Italian Renaissance ornamentation.  His New York commissions included Madison Square Garden (1891) and  the Washington Arch (1891). A versatile artist, he also designed jewelry,  furniture, and interiors.

Named for the white colour of the first ones dis�  covered, they actually occur in a variety of colours depending on their  temperature. They are extremely dense, typically containing the mass of  the Sun within the volume of the Earth. White dwarfs have exhausted all  their nuclear fuel and cannot produce heat by nuclear fusion to counter�  act their own gravity, which compresses the electrons and nuclei of their  atoms until they prevent further gravitational contraction. When a white  dwarf�s reservoir of thermal energy is exhausted (after several billion  years), it stops radiating and becomes a cold, inert stellar remnant, some�  times called a black dwarf. White dwarf stars are predicted to have an  upper mass limit, known as the Chandrasekhar limit (see Subrahmanyan  Chandrasekhar), of about 1.4 times the Sun�s mass. Dying stars that are  more massive undergo a supernova explosion. As members of binary stars,  white dwarf stars play an essential role in the outbursts of novas.</p><p>white-footed mouse See deer mouse</p><p>White Horse, Vale of the Valley, Oxfordshire, England.

The movement had  roots in 4th-century worship of the Buddha Amitabha, whose devotional  cult inspired Mao Ziyuan to form the White Lotus Society, a pious veg�  etarian group of monks and laity. By the 14th century it had developed  into a millenarian sect that combined MAiTREYAn and Manichaean beliefs  and was active in rebellions at the end of the Yuan dynasty. The society  became most prominent through its role in the White Lotus Rebellion  (1786-1804), a large-scale uprising in central China that contributed to  the fall of the Qing dynasty. It was eventually put down by peasants orga�  nized into local militia defense corps. Later Chinese governments came  to use the term White Lotus for all illegal millenarian groups. Some  observers saw the Nian Rebellion of 1852 as well as the secret society  behind the Boxer Rebellion as new manifestations of the White Lotus  Society.</p><p>White Monk See Cistercian</p><p>White Mountain, Battle of (1620) Decisive battle near Prague at  the beginning of the Thirty Years' War.

By the defeat, Bohemia lost  its independence, and Protestantism was exterminated until 1648.</p><p>White Mountains Segment of the Appalachian Mountains. It extends  87 mi (140 km) across north-central New Hampshire and into western  Maine. Containing the highest elevations in the northeastern U.S., its  loftiest peaks, mostly 5,000-6,000 ft (1,500-1,800 m) high, occur in a  series of summits that are named for U.S. presidents and make up the  Presidential Range. The highest point is Mount Washington. Most of the  White Mountains lie within the White Mountain National Forest.

Whitefish weigh about 2-5 lbs (1-2 kg); they eat insect larvae  and other small animals. The Lake Superior whitefish ( Coregonus clu-  peaformis), also called whiting or shad, is the largest of the lake white-  fishes. Ciscoes, or lake herring ( Coregonus artedi), are herringlike food  and sport fishes. The best sport fishes of the family are the Rocky Moun�  tain whitefish (Prosopium williamsoni ) and other round whitefishes.</p><p>whitefly Any sap-sucking member of the insect family Aleyrodidae  (order Homoptera). Nymphs are flat, oval, and usually covered with a  cottony substance. Adults, 0.08-0.12 in. (2-3 mm) long, are covered with  a white opaque powder and resemble moths. Whiteflies are abundant in  warm climates, on houseplants, and in greenhouses. The greenhouse  whitefly is one of the most abundant and destructive members of the fam�  ily. The citrus whitefly and citrus blackfly damage fruit and other crops  by sucking sap and producing honeydew, a by-product of digestion on  which grows a sooty fungus that ruins fruit and reduces the host plant�s  ability to photosynthesize.</p><p>Whitehead, Alfred North (b. Feb. 15, 1861, Ramsgate, Isle of Tha-  net, Kent, Eng.�d. Dec. 30, 1947, Cambridge, Mass., U.S.) British math�  ematician and philosopher. He taught principally at the University of  Cambridge (1885-1911) and Harvard University (1924-37). His Treatise  on Universal Algebra (1898) extended Boolean symbolic logic. He col�  laborated with Bertrand Russell on the epochal Principia Mathematica  (1910-13), which attempted to establish the thesis of LOGlClSM. In Process  and Reality (1929), his major work in metaphysics, he proposed that the  universe consists entirely of becomings, each a process of appropriating  and integrating the infinity of items provided by the antecedent universe  and by God. His other works include �On Mathematical Concepts of the  Material World� (1905), An Introduction to Mathematics (1911), Enquiry  Concerning the Principles of Natural Knowledge (1919), The Concept of  Nature (1920), Science and the Modern World (1925), and Religion in the  Making (1926). He received the Order of Merit in 1945.</p><p>Whitehorse City (pop., 2001: 19,058), capital of Yukon Territory,  Canada. Located on the Yukon River, it was founded during the Klondike  gold rush (1897-98) as a staging and distribution centre. Robert Service  got much of his inspiration for his ballads while working there. The ter�  ritorial capital since 1952, it is an important transportation centre on the  Alaska Highway, as well as an outfitting base for anglers and hunters.</p><p>Whiteman, Paul (b. March 28, 1890, Denver, Colo., U.S.�d. Dec.  29, 1967, Doylestown, Pa.) U.S. musician and bandleader. Whiteman  made his first records in 1920. His instrumental concept, known as �sym�  phonic jazz,� featured lush harmonies and simplified jazz rhythms but  little improvisation; he nevertheless became known as �The King of Jazz.�  Whiteman commissioned George Gershwin�s Rhapsody in Blue and con�  ducted its premiere in 1924. The Whiteman band featured, among others,  Bing Crosby, Bix Beiderbecke, and Jack Teagarden. His popularity waned in  the late 1940s, but he was a television-series host in the 1950s and occa�  sionally led bands up to the time of his death.</p><p>whiting Species ( Merlangius merlangus ) of common marine food fish  of the cod family (Gadidae), found in European waters and especially  abundant in the North Sea.

On his return he joined a caravan of 1,000 immigrants  to the Columbia River valley. He cared for Indian children in an 1847  measles epidemic, but he was accused of sorcery when many died while  white children survived. The Indians attacked the whites and massacred  14, including the Whitmans. Their deaths led Congress to organize the  Oregon Territory in 1848.</p><p>Whitman, Walt(er) (b. May 31, 1819, West Hills, Long Island, N.Y.,  U.S.�d. March 26, 1892, Camden,</p><p>N.J.) U.S. poet, journalist, and essay�  ist. Whitman lived in Brooklyn as a  boy and left school at age 12. He went  on to hold a great variety of jobs,  including writing and editing for  periodicals. His revolutionary poetry  dealt with extremely private experi�  ences (including sexuality) while cel�  ebrating the collective experience of  an idealized democratic American  life. His Leaves of Grass (1st ed.,</p><p>1855), revised and much expanded in  successive editions that incorporated  his subsequent poetry, was too frank  and unconventional to win wide  acceptance in its day, but it was  hailed by figures such as Ralph Waldo  Emerson and exerted a strong influ�  ence on American and foreign litera�  ture. Written without rhyme or  traditional metre, poems such as �I Sing the Body Electric� and �Song of  Myself� assert the beauty of the human body, physical health, and sexual�  ity; later editions included �Crossing Brooklyn Ferry,� �Out of the Cradle  Endlessly Rocking,� and the elegies on Abraham Lincoln �O Captain! My  Captain!� and �When Lilacs Last in the Dooryard Bloom�d.� Whitman  served as a volunteer in Washington hospitals during the Civil War. The  prose Democratic Vistas (1871) and Specimen Days &amp; Collect (1882-83)  drew on his wartime experiences and subsequent reflections. His powerful  influence in the 20th century can be seen in the work of poets as diverse as  Pablo Neruda, Fernando Pessoa, and Allen Ginsberg.</p><p>Whitney, Amos (b. Oct. 8, 1832, Biddeford, Maine, U.S.�d. Aug. 5,  1928, Portland, Maine) U.S. manufacturer. He was apprenticed at age 13.  In 1860, with Francis Pratt, he founded the firm of Pratt &amp; Whitney, origi�  nally to manufacture thread spoolers. It later diversified into the manu�  facture of innovative designs of guns, cannons, sewing machines, and  typesetting machines; instruments for measurement developed there  proved of great value to science and industry. Today a separate company,  formed from the tool works in 1925, produces aircraft engines and space-  propulsion systems as part of the United Technologies Corporation.</p><p>Whitney, Eli (b. Dec. 8, 1765, Westboro, Mass., U.S.�d. Jan. 8, 1825,  New Haven, Conn.) U.S. inventor, engineer, and manufacturer. He is best  remembered as the inventor of the cotton gin (1793), which led to greatly  increased production of the short-staple cotton grown in much of the  South, making the region prosperous. The most important innovation  credited to Whitney may be the concept of mass production of interchange�  able parts. His idea of manufacturing quantities of identical parts for  assembly into muskets, after undertaking in 1797 to supply the U.S. gov�  ernment with 10,000 muskets in two years, helped inaugurate the vastly  important American System of manufacture.</p><p>Whitney, Gertrude Vanderbilt orig. Gertrude Vanderbilt (b.</p><p>Jan. 9, 1875, New York, N.Y., U.S.�d. April 18, 1942, New York City)  U.S. sculptor and art patron. Great-granddaughter of Cornelius Vanderbilt,  she was born to great wealth and studied sculpture in New York City and  Paris. Among her major works were the Titanic Memorial (1914-31) in  Washington, D.C., and Victory Arch (1918-19) in New York. All her works  were simple, direct, and traditional. In 1929 she offered to donate her col�  lection of about 500 works by modern American artists to the Metropolitan  Museum of Art but was refused by the traditionalist director. The next year  she founded the Whitney Museum of American Art, also in New York City,  which opened in 1931; today it is the foremost museum of American art.</p><p>Whitney, John Hay (b.

The</p><p>son of Harry Payne Whitney and Gertrude Vanderbilt Whitney, �Jock�  Whitney attended Yale University and later the University of Oxford,  which he left to manage the family fortune on his father�s death. He  became an internationally ranked polo player, his stables produced notable  racehorses, he invested in successful films and Broadway plays, and he  boasted one of the finest art collections in the U.S. As a combat-  intelligence captain in World War II, he was captured in France but  escaped; he was later awarded the Legion of Merit. He served as ambas�  sador to Britain (1956-61). As publisher and (from 1961) editor in chief  of the New York Herald Tribune , he tried to revitalize the paper, but it  folded in 1966. He founded the John Hay Whitney Foundation in 1946.</p><p>Whitney, Mount Peak in the Sierra Nevada, southeast-central Califor�  nia, U.S. Located in Sequoia National Park, it is 14,494 ft (4,418 m) high,  the highest point in the continental U.S. outside of Alaska.

He practiced law  in New York City, where he helped Samuel Tilden overthrow the corrupt  political boss William Marcy Tweed; he also served as corporation counsel  for the city (1875-82). As U.S. secretary of the navy (1885-89), he rebuilt  the neglected fleet with a major shipbuilding program that included the  battleship Maine (see destruction of the Maine). He returned to New York,  where he became co-owner of the city�s first rapid-transit system.</p><p>Whittier, John Greenleaf (b. Dec. 17, 1807, near Haverhill, Mass.,  U.S.�d. Sept. 7, 1892, Hampton Falls, Mass.) U.S. poet and reformer. A  Quaker bom on a farm, Whittier had limited education but was early  acquainted with poetry. He became involved in journalism and published  his first volume of poems in 1831. During 1833�42 he embraced the abo�  litionism of William Lloyd Garrison and became a prominent antislavery  crusader. Thereafter he continued to support humanitarian causes while  publishing further poetry volumes. After the Civil War he was noted for  his vivid portrayals of rural New England life. His best-known poem is  the nostalgic pastoral �Snow-Bound� (1866); others include �Maud  Muller� (1854) and �Barbara Frietchie� (1863).</p><p>Whittington, Richard known as Dick Whittington (d.

The  son of a knight, he earned a vast fortune as a merchant and made loans  to Henry IV and Henry V, then entered city politics and served three terms  as lord mayor. In legend he is portrayed as an orphan who ventures his  only possession, a cat, as an item to be sold on one of his master�s trad�  ing ships. Ill-treated by the cook, he runs away, but at the edge of the city  he hears the bells say, �Turn again, Whittington, lord mayor of great Lon�  don.� He returns to find that his cat has been sold for a great sum to a  Moorish ruler plagued by rats.

He obtained his first patent for a  turbojet engine in 1930, and in 1936 he cofounded Power Jets Ltd. The  outbreak of World War II spurred the British government to support Whit�  tle�s work, and the first jet-powered aircraft took off in 1941. He was  knighted in 1948 and awarded the Order of Merit in 1986.</p><p>Whitworth, Sir Joseph (b. Dec. 21, 1803, Stockport, Cheshire,  Eng.�d.

He followed this with a measuring machine  and a system of accurate dimensional standards or master gauges to go  with it, and screws with standardized threads (1841), among other inno�  vations. His machine tools became internationally known for their accu�  racy and quality.</p><p>WHO See World Health Organization</p><p>wholesaling Selling of merchandise to anyone other than a retail cus�  tomer. The term may include sales to a retailer, wholesaler, broker, dis�  tributor, or business enterprise. Wholesaling usually involves sales in  quantity and at a cost significantly lower than the average retail price. It  has become an important step in the supply chain since the introduction  of mass production and mass marketing techniques in the 19th century.  Without wholesalers, manufacturers would have to market their products  directly to a huge number of customers at high unit costs, and buyers  would have to deal with an inconveniently large number of suppliers.</p><p>Walt Whitman, photograph by  Mathew Brady.</p><p>LIBRARY OF CONGRESS, WASHINGTON, D.C.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2056 I whooping cough &#x25BA; Wiesbaden</p><p>There are three major categories of wholesalers. Merchant wholesalers,  the most important category, are independent businesses that buy mer�  chandise in great quantities from manufacturers and resell it to retailers.  Manufacturers� sales branches are businesses founded by manufacturers  to sell directly to retailers. Merchandise agents and brokers represent  various manufacturers; they usually do not buy the merchandise they  handle but instead arrange for shelf space and the display of merchandise.  So-called warehouse stores sell large quantities of goods at near-wholesale  prices.

He worked professionally as a fire-prevention  authority. The concept he developed (under Edward Sapir�s influence) of  the equation of culture and language became known as the Whorf (or  Sapir-Whorf) hypothesis. He maintained that a language�s structure tends  to condition the ways its speakers think�for example, that the way a  people views time and punctuality may be influenced by the types of verb  tenses in its language. Whorf was also noted for his studies of Uto-Aztecan  languages, especially Hopi, and Mayan hieroglyphic writing.</p><p>Whymper Yhwim-psrV Edward (b. April 27, 1840, London,  Eng.�d.

In 1865 he made the first ascent of the Matterhorn; an accident on the  descent caused the death of four of his companions. His Scrambles  Amongst the Alps (1871) and Travels Amongst the Great Andes (1892)  describe his experiences and are illustrated with his own engravings.</p><p>Wicca Modem Western witchcraft movement. Some practitioners con�  sider Wicca the religion of pre-Christian Europe, forced underground by  the Christian church. That thesis is not accepted by historians, and mod�  ern Wicca is usually dated to the work of Gerald B. Gardner (1884-1964)  and Doreen Valiente (1922-1999), who, after the repeal of the last Witch�  craft Act in England (1951), went public with their cult of witchcraft,  which centered on a homed god of fertility and a great earth goddess.  Gardner is credited with introducing the term Wicca. So-called �Dianic�  Wicca focuses on the Goddess as the supreme being and usually excludes  men. Wiccans share a belief in the importance of the feminine principle,  a deep respect for nature, and a pantheistic and polytheistic worldview.  They practice some form of ritual magic, almost always considered good  or constructive. Some are solitary practitioners; others belong to covens.</p><p>Wichita Vwi-cho-.toV City (pop., 2000: 344,284), south-central Kansas,  U.S. On the Arkansas River, the city was founded in 1864 as a trading post  on the site of a Wichita Indian village; it developed with the Texas cattle  trade along the Chisholm Trail and the rapid spread of agricultural settle�  ment along the Atchison, Topeka and Santa Fe Railroad Co. In the 1870s</p><p>it was a major cattle-shipping centre. It developed as a centre of the air�  craft industry in the 1920s.

Its members had close ties  to the artists of the Vienna Sezession and the Art Nouveau movement. The  Wiener Werkstatte�s work in jewelry, furnishings, interior design, fash�  ion, and other areas, which often celebrated the beauty of geometry,  became widely known for elegance and innovation, and this �square style�  influenced the work of the Bauhaus craftsmen in the 1920s as well as the  work of Frank Lloyd Wright.</p><p>Wiesbaden Vves-.ba-donN City (pop., 2002 est.: 271,276), capital of  Hesse, southern Germany.

Made an imperial city in 1241, it passed to the counts of Nassau in  1255. It was capital of the duchy of Nassau from 1806 to 1866, when it  passed to Prussia. After World War I it was the seat of the Rhineland Com�  mission under French and British occupation (1918-29). In 1946 Wies�  baden became the capital of the newly created state of Hesse. It was  particularly noted for its spa in the 18th and 19th centuries, when it was  frequented by Johann W. von Goethe, Johannes Brahms, and Fyodor Dos�  toyevsky.

By analyzing the flow of nerve impulses from the eye in laboratory  animals, they detected many structural and functional details of the visual  cortex, in the occipital lobes of the cerebral cortex. Their studies of the  effects of visual impairments in young animals lent strong support to the  view that prompt surgery is crucial to correct certain eye defects in new�  born children.

Ancient Egyptians, Assyrians, Phoenicians, Greeks, and  Romans used wigs, often as protection from the sun. In the West the wig  first became an acceptable form of adornment or corrective for nature�s  defects in the 16th century, and men�s perukes, or periwigs, came into  widespread use in the 17th century. Men�s wigs were common through�  out the 18th century. Women wore wigs surreptitiously in the 18th-19th  centuries; after the development of inexpensive synthetic wigs in the 20th  century, women�s wigs increased in popularity. In East Asia wigs have  been used rarely except in the Chinese and Japanese theatre.</p><p>Wigan \'wi-gon\ Town and metropolitan borough (pop., 2001: 301,417),  northwestern Greater Manchester, historic county of Lancashire, England.  It lies along the River Douglas and the Leeds and Liverpool Canal. Coal  was mined from the 14th century, and textiles were produced in the area  as early as the 16th century. Industrialization in the late 18th century was  accelerated by the building of canals and railways. Textiles have declined  in importance, and the last coal mine closed in 1993. New industries,  including food processing, paper and packaging, and electrical engineer�  ing, have broadened the economy.

Separated from mainland Hampshire by the Solent,  the island has an area of 147 sq mi (381 sq km). Its main town is New�  port. The backbone of the Isle of Wight is a chalk ridge that extends across  its entire breadth, the thickest bed of chalk in the British Isles. The Needles  are three detached masses of chalk that lie off the island�s westernmost  point and rise to about 100 ft (30 m). Three rivers, the Eastern Yar, the  Medina, and the Western Yar, flow northward into the Solent. A major  British maximum security prison is located at Parkhurst. Boatbuilding,  marine engineering, and the aerospace, plastics, and electronics industries  are economically important. The island�s warm, sunny climate has made  it a popular vacation spot.</p><p>Wightman, Hazel Hotchkiss orig. Hazel Virginia Hotchkiss</p><p>(b. Dec. 20, 1886, Healdsburg, Calif., U.S.�d.

After studies at the University of Berlin, he immigrated to  the U.S. in 1930 and joined the faculty of Princeton University. He was  instrumental in getting the Manhattan Project started and was present  when Enrico Fermi initiated the first chain reaction. He determined that the  nuclear force is short-range and does not involve an electric charge, using  group theory to investigate atomic structure. His name was given to sev�  eral formulations, including the Breit-Wigner formula, which describes  resonant nuclear reactions. He won a 1963 Nobel Prize (shared with Maria  Mayer and Hans Jensen [1907-73], who won for unrelated work) for his  insights into quantum mechanics, especially principles governing interac�  tion of protons and neutrons in the nucleus and his formulation of the law  of conservation of parity (see conservation law).

Son  of an eminent surgeon, Wilde  attended Trinity College, Dublin,  and later Oxford University, becom�  ing widely known for his wit while  still an undergraduate. A spokesman  for Aestheticism, in the early 1880s he  gave a lecture tour in the U.S. and  established himself in London  circles by his wit and flamboyance.</p><p>His only novel, The Picture of  Dorian Gray (1891), combines  gothic elements with mockery of  bourgeois morality. His macabre  play Salome (1893) was later  adapted as the libretto of Richard  Strauss�s opera; his other plays, all  successes, include Lady Winder�  mere�s Fan (1893), A Woman of No  Importance (1893), and An Ideal  Husband (1895). His greatest work  was the comedy The Importance of Being Earnest (1899), a satire of Vic�  torian social hypocrisy. Two critical dialogues, �The Decay of Lying� and  �The Critic as Artist,� are admired as equally brilliant. Though happily  married, in 1891 he began an intimate relationship with the young Lord  Alfred Douglas, son of the marquess of Queensberry. Accused by Queens-  berry of being a sodomite, Wilde sued for libel and lost, then was arrested  for sodomy and convicted in a trial that became internationally notorious.  Imprisoned at Reading Gaol (1895-97), he wrote a recriminatory letter  to his lover that was edited and published as De Profundis (1905). After  his release, he moved to Paris; his only later work was The Ballad of  Reading Gaol (1898), on inhumane prison conditions.

His play Our Town (1938, Pulitzer Prize), which  became one of the most enduringly popular of all American plays, was  followed by the successful The Skin of Our Teeth (1942, Pulitzer Prize).  In them he rejected naturalism, often discarding props and scenery, using  deliberate anachronisms, and having the characters address the audience  directly. His farcical play The Matchmaker (1954) was adapted into the  musical Hello, Dolly! (1964).

As bishop of York, he built a  monastery at Hexham and traveled twice to Rome to defend the see of York  in jurisdictional controversies with the see of Canterbury (679, 704). A  quarrel over the division of his diocese obliged Wilfrid to take refuge in  Sussex, where he Christianized the people and founded a monastery at Sel-  sey; he later served as bishop of Lichfield in Mercia.

In 1051 Edward the Confessor promised to  make him heir to the English throne, but on Edward�s death in 1066,  Harold Godwineson, earl of Wessex (Harold II), was accepted as king.  Determined to assert his right to the throne, William sailed from Nor�  mandy with an invasion force, defeated Harold at the Battle of Hastings,  and was crowned king. The Norman Conquest was thus completed,  though English rebellions continued until 1071. To secure England�s fron�  tiers, William invaded Scotland (1072) and Wales (1081).

He advocated the use of force against  the rebels in 1848. The military governor of Rhineland province from  1849, he succeeded his brother on the Prussian throne in 1861. A conser�  vative and a supporter of military reform, William insisted on a three-year  term of military conscription, which the liberal lower chamber rejected  in 1862. William was ready to abdicate but was dissuaded by Otto von  Bismarck, whom he had installed as prime minister (1862). He cautiously  supported Bismarck�s policies in the Seven Weeks' War and the Franco-  Prussian War.

He was educated  at the Habsburg imperial court in Brussels, then appointed by Philip II to  the council of state (1555). He helped negotiate the Treaty of Cateau-  Cambresis, earning his byname for keeping silent about secret policy deci�  sions, and was named stadtholder (governor) in Holland, Zeeland, and  Utrecht in 1559. Increasingly opposed to Philip�s strict ordinances against  Protestants, he led a revolt in 1568 that proved unsuccessful, but in 1572  he succeeded in uniting the northern provinces. He was proclaimed their  stadtholder, and his position was solidified by the Pacification of Ghent  (1576).

A tyrannical ruler, he brutally punished the lead�  ers of a second revolt (1095). He forced St. Anselm, archbishop of Can�  terbury, to leave England and seized his lands (1097). He reduced the  Scottish kings to vassals (1093), subjugated Wales (1097), and waged war  on Normandy (1089-96), gaining control when Robert mortgaged the  duchy. His death in a hunting accident may have been an assassination  ordered by his brother Henry (later Henry I).</p><p>William II German Friedrich Wilhelm Viktor Albert known as  Kaiser Wilhelm (b. Jan. 27, 1859, Potsdam, near Berlin, Prussia�d.  June 4, 1941, Doom, Neth.) German emperor (kaiser) and king of Prus�  sia (1888-1918). Son of the future Frederick III and grandson of Britain�s  Queen Victoria, William succeeded his father to the throne in 1888. Two  years later, he forced the resignation of Otto von Bismarck. He was char�  acterized by his frequently militaristic manner and by his vacillating poli�  cies that undermined those of his chancellors, including Leo, count von  Caprivi, and Bernhard, prince von Bulow. From 1897 he encouraged Adm.  Alfred von Tirpitz to strengthen the German fleet and challenged France�s  position in Morocco (see Moroccan crises). He sided with Austria-  Hungary in the crisis with Serbia (1914), and in World War I he encour�  aged the grandiose war aims of the generals and politicians. After  Germany�s defeat, he fled to The Netherlands, ending the monarchy in  Germany, and lived in exile until his death.</p><p>William II Italian Guglielmo known as William the Good (b.</p><p>1154�d. Nov. 18, 1189, Palermo, Kingdom of Sicily) Last Norman king  of Sicily (1166-89). His mother served as regent until 1171, after which  he ruled alone, winning a reputation for clemency and justice. His friend�  ship with Manuel I Comnenus ended when the Byzantine emperor thwarted  William�s proposed marriage to his daughter. Turning against the Byzan�  tines, William allied with Frederick I Barbarossa. He agreed to his aunt�s  marriage to Frederick�s son Henry (later Henry VI), giving Henry a claim  to Sicily. He attacked the Byzantines (1185) with early success but was  defeated within sight of Constantinople.</p><p>William II Dutch Willem (b. May 27, 1626, The Hague, United Prov�  inces of the Netherlands�d. Nov. 6, 1650, The Hague) Prince of Orange,  count of Nassau, and stadtholder of the Netherlands (1647-50). The son  of Frederick Henry, prince of Orange, he married Mary Stuart, eldest  daughter of Charles I of England, in 1641 and later succeeded to his  father�s offices (1647), which included the stadtholdership of all the prov�  inces of the Netherlands except Friesland. Despite the treaty with Spain  in 1648 that recognized the independence of the United Provinces, he  planned to conquer part of the Spanish Netherlands (modern Belgium).  He imprisoned members of the assembly of Holland who opposed his war  policy but died of smallpox before his influence could be tested.</p><p>William II Dutch Willem Frederik George Lodewijk (b. Dec.  6, 1792, The Hague, United Provinces of the Netherlands�d. March 17,  1849, Tilburg, Neth.) King of The Netherlands and grand duke of Lux�</p><p>embourg ( 1840�49). Son of William I, he lived in exile with his family in  England from 1795. He commanded Dutch troops in the Battle of Water�  loo (1815). Sent by his father to Belgium in 1830 to appease the rebels,  he failed to stop the independence movement. In 1840 he became king  of The Netherlands on his father�s abdication. As king, he helped stabi�  lize the economy. In 1848 he oversaw passage of a new liberal constitu�  tion that expanded the authority of the ministers and assembly, established  direct elections, and secured basic civil liberties.</p><p>William III Dutch Willem Hendrik (b. Nov. 14, 1650, The Hague,  United Provinces of the Netherlands�d. March 19, 1702, London, Eng.)  Stadtholder of the United Provinces of the Netherlands (1672-1702) and  king of England (1689-1702). Son of William II, prince of Orange, and  Mary Stuart, daughter of Charles I of England, he was born in The Hague  soon after his father�s death. The Act of Seclusion (1654) that barred the  house of Orange from power in the United Provinces was rescinded in  1660, and William was appointed captain general and named stadtholder  by popular acclaim in 1672. He successfully defended his country against  Charles II of England and Louis XIV of France. In 1677 he married Mary  (later Queen Mary II), daughter of the English duke of York (later James  II). In 1688 William was invited by James�s opponents to intervene against  the Catholic ruler, and he landed with a Dutch army in Devon, Eng. He  and Mary were proclaimed joint rulers of England in 1689; he ruled alone  after Mary�s death in 1694. He directed the European opposition to Louis  XIV, which eventually led to the War of the Grand Alliance after Will�  iam�s death. In Britain he secured religious toleration and strengthened  Parliament, granting independence to the judiciary in the Act of Settle�  ment.</p><p>William III Dutch Willem Alexander Paul Frederik Lodewijk</p><p>(b. Feb. 19, 1817, Brussels, Belg.�d. Nov. 23, 1890, Apeldoom, Neth.)  King of The Netherlands and grand duke of Luxembourg (1849-90). Son  of William II, he succeeded to the throne on his father�s death in 1849.  Opposed to the liberal constitution of 1848, he adopted an anti-Catholic  posture and from 1862 to 1868 was able to rule through the cabinet. He  tried to sell his sovereignty over Luxembourg to France (1867) but yielded  to Prussia�s demand that the area be independent. Following this crisis,  his influence over parliament declined. On his death, he was succeeded  by his daughter, Wilhelmina.</p><p>William IV (b. Aug. 21, 1765, London, Eng.�d. June 20, 1837, Wind�  sor Castle, near London) King of Great Britain and Ireland and of Hanover  (1830-37). The son of George III, he entered the royal navy at age 13,  fought in the American Revolution, and served in the West Indies, leav�  ing the navy as a rear admiral in 1790 (he was later called �the Sailor  King�). He angered his father by his numerous love affairs and fathered  10 illegitimate children by the actress Dorothea Jordan (1761-1816). In  1830 he succeeded his brother George IV as king. Opposed to parliamen�  tary reform, William delayed consideration of the Reform Bill of 1832,  but his prime minister, Earl Grey, persuaded him to promise to create  enough peers in the House of Lords to carry it, forcing its passage. On  William�s death, the British crown passed to his niece, Victoria, and the  Hanoverian crown to his brother Ernest Augustus, duke of Cumberland</p><p>(1771-1851).</p><p>William and Mary, College of State-supported college in Will�  iamsburg, Va.

Named bishop of Paris in 1228, William was  a reformer who defended the rising mendicant orders against attacks by  the secular clergy. After the church condemned the works of Aristotle, he  became one of the first Western scholars to attempt to incorporate into  Christianity whatever in Aristotle�s thought was compatible with it. He  was influenced by Avicenna and by the Neoplatonism of St. Augustine.

Seeing no reason to avoid the ratio�  nal analysis of Christian revelation, he was on the verge of reorganizing the  curriculum when he died. In his principal work, usually called the Summa  aurea (written 1215-20), he treated such matters as God�s triune nature, the  problem of human choice, and the nature of virtue.</p><p>William of Ockham See William of Ockham  William Rufus See William II (England)</p><p>William Tell See William Tell</p><p>William the Conqueror See William I (England)</p><p>William the Good See William II (Sicily)</p><p>William the Silent See William I (Netherlands)</p><p>Williams, Daniel Hale (b.

He began playing guitar at age  8, made his radio debut at 13, and formed his first band, Hank Williams  and his Drifting Cowboys, at 14. With the help of Fred Rose, his �Lovesick  Blues� became a smash hit in 1949, and he joined the Grand Ole Opry  that year after an extraordinary debut appearance. Among his best-selling  recordings were �I�m So Lonesome I Could Cry,� �Jambalaya,� �Your  Cheatin� Heart,� and �Hey, Good Lookin�.� He wrote almost all the songs  he recorded.

She coordinated the launch of the ICBL with the coop�  eration of six international organizations, with the mission to abolish the  use of antipersonnel land mines, of which tens of millions lay unexploded  in more than 70 countries. Her efforts bore fruit in December 1997, when  the Mine Ban Treaty was signed by more than 100 countries in Ottawa.  By 2003 some 130 nations had ratified the treaty, but not the major mine-  producing ones, such as the United States, Russia, and China.

Willows are valued as ornamentals and for their shade, erosion  control, and timber. Certain species yield salicin, the source of salicylic  acid used in pain relievers. All species have alternate, usually narrow  leaves, catkins, and seeds with long, silky hairs. Pussy willows, the  male form of several shrubby species, have woolly catkins that form  before the leaves appear and are considered one of the first signs of spring.

His invention of the Wilson cloud chamber, a device that became  widely used in the study of radioactivity, X rays, cosmic rays, and other  particle phenomena, also led to the later development of the bubble cham�  ber. He shared the 1927 Nobel Prize for Physics with Arthur Compton.</p><p>Wilson, Colin (Henry) (b. June 26, 1931, Leicester, Leicestershire,  Eng.) British writer. Born into a working-class family, he initially thought  of a career in science, then gravitated toward writing. At age 24 he pub�  lished The Outsider (1957), a study of 20th-century alienation that had  phenomenal success. His next book was dismissed as unoriginal or super�  ficial, but Ritual in the Dark (1960) and Adrift in Soho (1961) helped  repair his reputation. Many of his more than 70 books deal with the psy�  chology of crime, the occult, human sexuality, and his own existential  philosophy. Alien Dawn (1998) discusses the UFO phenomenon.</p><p>Wilson, Edmund (b. May 8, 1895, Red Bank, N.J., U.S.�d. June 12,  1972, Talcottville, N.Y.) U.S. critic  and essayist. He attended Princeton  University and initially worked as a  reporter and magazine editor. Much  of his writing, in which he probed  diverse subjects with scholarship and  common sense in clear and precise  prose, was published in The New  Republic and The New Yorker.</p><p>Among his influential critical works  are Axel�s Castle (1931), a survey of  the Symbolist poets; To the Finland  Station (1940), a study of the think�  ers who set the stage for the Russian  Revolution; and Patriotic Gore  (1962), analyzing American Civil  War literature. His other writings  include plays, poetry, the short-story  collection Memoirs of Hecate County (1946), and five volumes of post�  humously published journals. He was widely regarded as the leading critic  of his time.</p><p>Wilson, Edmund B(eecher) (b. Oct. 19, 1856, Geneva, Ill., U.S.�d.  March 3, 1939, New York, N.Y.) U.S. cell biologist. He joined the Colum�  bia University faculty in 1891, where he became established as a pioneer  in work on cell lineage (tracing the formation of different kinds of tissues  from individual cells). His interests later extended to internal cellular  organization and the problem of sex determination, leading to a series of  papers (1905) on the role of chromosomes. Recognizing the importance  of Gregor Mendel�s findings, he realized that the role of chromosomes  went far beyond the determination of sex and envisioned their function  as important components in heredity as a whole, ideas that were a pow�  erful force in shaping future genetic research.</p><p>Wilson, Edward O(sborne) (b. June 10, 1929, Birmingham, Ala.,  U.S.) U.S. biologist. He received his Ph.D. from Harvard University,  where he taught from 1956. Recognized as the world�s leading authority  on ants, he discovered their use of pheromone for communication. His  The Insect Societies (1971) was the definitive treatment of the subject. In  1975 he published Sociobiology, a highly controversial and influential  study of the genetic basis of social behaviour in which he claimed that  even a characteristic such as unselfish generosity may be genetically based  and may have evolved through natural selection, that preservation of the  gene rather than the individual is the focus of evolutionary strategy, and  that the essentially biological principles on which animal societies are  based apply also to human social behaviour. In On Human Nature (1978,  Pulitzer Prize) he explored sociobiology�s implications in regard to human  aggression, sexuality, and ethics. With Bert Holldobler he wrote the major  study The Ants (1990, Pulitzer Prize). In The Diversity of Life (1992) he  examined how the world�s species became diverse and the massive extinc�</p><p>tions caused by 20th-century human activities. In Consilience: The Unity  of Knowledge (1998) he proposed that all of existence can be organized  and understood in accordance with a few fundamental natural laws.</p><p>Wilson, (James) Harold, Baron Wilson (of Rievaulx) (b.</p><p>March 11, 1916, Huddersfield, Yorkshire, Eng.�d. May 24, 1995, Lon�  don) British politician and prime minister (1964-70, 1974-76). The son of  an industrial chemist, he was educated at the University of Oxford, where  he collaborated with William H. Beveridge on work that led to the latter�s  1942 report. In World War II he was drafted into the civil service and pro�  duced a study of the mining industry. His book New Deal for Coal (1945)  was the basis for the Labour Party�s plan to nationalize the coal mines. He  was elected to the House of Commons in 1945 and appointed president of  the Board of Trade (1947-51). Elected leader of the Labour Party in 1963,  he became prime minister in 1964. He widened the party�s voting majority  in 1966 but his popularity declined in the late 1960s, partly because of his  assumption of direct responsibility for the economy shortly before the  pound was devalued in 1967. In his second term, he confirmed Britain�s  membership in the European Economic Community (1975). He resigned  unexpectedly in 1976 and was created a life peer in 1983.</p><p>Wilson, Harriet E. orig. Harriet E. Adams (b. 1828?, Milford,  N.H.?, U.S.�d. 1863?, Boston, Mass.?) U.S. writer, probably the first  African American to publish a novel in English in the U.S. Little is known  of her history until 1850. She may have been an indentured servant in  Milford, N.H., before becoming a domestic in Massachusetts. In 1851 she  married a fugitive slave who ran off to sea before the birth of their son.  Her one book, written to make money to reclaim her son from foster care,  is Our Nig (1859), a largely autobiographical novel that treats racism in  the pre-Civil War North. After 1863 Wilson disappeared from the public  record.</p><p>Wilson, J(ohn) Tuzo (b. Oct. 24, 1908, Ottawa, Ont., Can.�d. April  15, 1993, Toronto, Ont.) Canadian geologist and geophysicist. He was the  first graduate of a Canadian university in the field of geophysical studies  (1930). After World War II he became a professor of geophysics at the  University of Toronto. He established global patterns of faulting and the  structure of the continents, and in the 1960s he became the world�s lead�  ing spokesman for the theory of continental drift. His studies also were  important for the hypothesis of seafloor spreading and the theory of con�  vection currents within the Earth. A range of mountains in Antarctica is  named for him.</p><p>Wilson, James (b. Sept. 14, 1742, Fife, Scot.�d. Aug. 21, 1798,  Edenton, N.C., U.S.) American colonial lawyer, politician, and jurist.  Immigrating to North America in 1765, he taught Greek and rhetoric in  the College of Philadelphia and then studied law under John Dickinson.  In 1774 he published a widely read treatise proposing a commonwealth  of British colonies. He was a member of the Committee of Correspon�  dence, a delegate to the Continental Congress (1775-77), and a signer of  the Declaration of Independence. He helped draft the U.S. Constitution  and the Pennsylvania state constitution and delivered lectures that became  landmarks in American jurisprudence. He served on the U.S. Supreme  Court (1789-98).</p><p>Wilson, Lanford (Eugene) (b. April 13, 1937, Lebanon, Mo., U.S.)  U.S. playwright. He began writing plays in 1962 and became cofounder  and director of the Circle Repertory Company (1969-95), a regional the�  atre in New York City. His plays, which are known for their experimen�  tal staging, simultaneous dialogue, and deferred character exposition,  include Lemon Sky (1970), the long-running hit The Hot l Baltimore  (1973), The Mound Builders (1975), Talley�s Folly (1979, Pulitzer Prize),  Burn This (1987), and By the Sea (1996).</p><p>Wilson, Richard (b. Aug. 1, 1714, Penegoes, Montgomeryshire,  Wales�d. May 15, 1782, Llanberis, Carnarvonshire) Welsh landscape  painter. He worked as a portraitist for many years, but after a lengthy stay  in Italy (1750-57) he worked almost exclusively in landscape, except for  numerous drawings of Roman sites and buildings that he used in com�  posing Italianate landscapes. A set of drawings made for Lord Dartmouth  (dated 1754) show that he tempered his delicate observation of light and  distance with the discipline of such 17th-century Classicists as Nicolas  Poussin. The landscapes he produced after his return to Britain influenced  J.M.W. Turner and John Constable.</p></section><section><p>Wilson, Robert W(oodrow) (b.

These recordings, often featuring vocalist Billie Holiday, are classics of  small-group swing. Wilson joined Benny Goodman�s trio in 1936. After  1940 he worked primarily as a leader of small ensembles or as a solo  pianist, showcasing his tasteful and refined amalgam of the styles of Fats  Waller, Earl Hines, and Art Tatum.</p><p>Wilson, William Julius (b. Dec. 20, 1935, Derry Township, Pa., U.S.)  U.S. sociologist. He spent 24 years on the University of Chicago faculty  before moving to Harvard University in 1996. In The Declining Signifi�  cance of Race (1978) and The Truly Disadvantaged (1987) he contends  that entrenched black poverty stems neither from racism nor from welfare  dependency but from changes in the global economy that pull low-skilled  manufacturing jobs out of the inner city. In When Work Disappears (1996)  he discusses, among other issues, how chronic joblessness erodes work  skills. Wilson holds that only �race neutral� programs such as universal  health care and government-financed jobs can alleviate the problems of  black poverty in the inner city.</p><p>Wilson, (Thomas) Woodrow (b. Dec. 28, 1856, Staunton, Va.,  U.S.�d. Feb. 3, 1924, Washington, D.C.) 28th president of the U.S.  (1913-21). He earned a law degree and later received his doctorate from  Johns Hopkins University. He taught political science at Princeton Uni�  versity (1890-1902). As its president (1902-10), he introduced various  reforms. With the support of progressives, he was elected governor of  New Jersey. His reform measures attracted national attention, and he  became the Democratic Party presidential nominee in 1912. His campaign  emphasized his progressive New Freedom policy, and he defeated The�  odore Roosevelt and William H. Taft to win the presidency. As president,  he approved legislation that lowered tariffs, created the Federal Reserve  System, established the Federal Trade Commission, and strengthened  labour unions. In foreign affairs he promoted self-government for the  Philippines and sought to contain the Mexican civil war. From 1914 he  maintained U.S. neutrality in World War I, offering to mediate a settle�  ment and initiate peace negotiations. After the sinking of the Lusitania  (1915) and other unarmed ships, he obtained a pledge from Germany to  stop its submarine campaign. Campaigning on the theme that he had �kept  us out of war,� he was narrowly reelected in 1916, defeating Charles Evans  Hughes. Germany�s renewed submarine attacks on unarmed passenger  ships caused Wilson to ask for a declaration of war in April 1917. In a  continuing effort to negotiate a peace agreement, he presented the Four�  teen Points (1918). He led the U.S. delegation to the Paris Peace Confer�  ence. The Treaty of Versailles faced opposition in the Senate from the  Republican majority led by Henry Cabot Lodge. In search of popular sup�  port for the treaty and its provision creating the League of Nations, Wil�  son began a cross-country speaking tour, during which he collapsed. He  returned to Washington, D.C. (September 1919), where he suffered a mas�  sive stroke that left him partially paralyzed. In the months that followed,  his wife Edith controlled access to him, made some decisions by default,  and engineered a cover-up of his condition. He rejected any attempts to  compromise his version of the League of Nations and urged his Senate  followers to vote against ratification of the treaty, which was defeated in  1920. He was awarded the 1919 Nobel Prize for Peace.</p><p>Wilson disease or hepatolenticular Vhi-.pat-o-bn-.tik-yo-bA  degeneration Recessive hereditary defect (see recessiveness) that  impairs one�s ability to metabolize copper. In affected persons, copper  accumulates in the basal ganglia (see ganglion) of the brain (involved in  control of movement), causing progressive degeneration; forms a brown�  ish ring at the margin of the cornea of the eye; and is deposited in the  liver, gradually leading to cirrhosis. Other symptoms include tremor, lack  of coordination, and personality changes. The disease usually appears in  the person�s teen years or twenties. Early diagnosis and treatment with a  high-protein, low-copper diet and a substance to chelate copper can  reverse the effects and prevent permanent brain and liver damage.</p><p>Wilson's Promontory Southernmost point of the Australian main�  land, southern Victoria.

He entered vaudeville at age 13 and eventually began  contributing tidbits to the Vaudeville News. Later, as a full-time gossip  columnist, he moved to the New York Daily Mirror, where his widely  syndicated column appeared until 1963. He had a weekly radio program  from 1932 until the early 1950s. A prolific phrasemaker, he was noted for  his slangy Broadway idiom. His opinionated news reports brought him a  massive audience and great influence from the 1930s through the 1950s.  He served as the unseen narrator of the television drama series The  Untouchables (1959-63).</p><p>Winchester City and administrative district (pop., 2001: 107,213), cen�  tral part of the administrative and historic county of Hampshire, England.  Initially founded by Celtic peoples, it became important as Venta Belgarum  under Roman rule. It was the capital of Wessex and a centre of learning  under Alfred the Great; later it was the seat of the Danish king Canute�s  government. It remained important under the Norman kings until the emer�  gence of London as the sole capital of England late in the 12th century.

He initially set up a factory to manufacture dress shirts,  and his success enabled him to purchase the Volcanic Repeating Arms  Co. (1857), which became the Winchester Repeating Arms Co. (1867).  His chief gun designer, B.T. Henry, created the lever-action Henry repeat�  ing rifle (patented 1860). Widely used in the American Civil War, it was  the forerunner of a long line of Winchester guns, including the famous  Model 73, a favourite weapon of settlers in the American West.</p><p>Winckelmann Vviq-kol-.manA  English Vwiq-kol-monX, Johann  (Joachim) (b.

Wind is an  important factor in determining and controlling climate and weather. It is  also the generating force of most ocean and freshwater waves. Wind  occurs because of horizontal and vertical differences in atmospheric pres�  sure. The general pattern of winds over the Earth is known as the general  circulation, and specific winds are named for the direction from which  they originate (e.g., a wind blowing from west to east is a westerly). Wind  speeds are often classified according to the Beaufort scale.</p><p>Beaufort Scale</p><p>Wind speed.</p><p>No.</p><p>Name</p><p>mph (kph)</p><p>Description</p><p>0</p><p>Calm</p><p>&lt;i (&lt;d</p><p>Calm; smoke rises vertically</p><p>1</p><p>Light air</p><p>1-3 (1-5)</p><p>Direction of wind shown by  smoke but not by wind vanes</p><p>2</p><p>Light breeze</p><p>4-7 (6-11)</p><p>Wind felt on face; leaves rustle;  wind vane moves</p><p>3</p><p>Gentle breeze</p><p>8-12 (12-19)</p><p>Leaves and small twigs in constant  motion; wind extends light flag</p><p>4</p><p>Moderate</p><p>breeze</p><p>13-18 (20-28)</p><p>Wind raises dust and loose paper;  small branches move</p><p>5</p><p>Fresh breeze</p><p>19-24 (29-38)</p><p>Small-leaved trees begin to sway;  crested wavelets form on inland  waters</p><p>6</p><p>Strong breeze</p><p>25-31 (39-49)</p><p>Large branches move; overhead  wires whistle; umbrellas difficult to  control</p><p>7</p><p>Moderate gale  or near gale</p><p>32-38 (50-61)</p><p>Whole trees</p><p>sway; walking against wind is  difficult</p><p>8</p><p>Fresh gale or  gale</p><p>39-46 (62-74)</p><p>Twigs break off  trees; moving cars veer</p><p>9</p><p>Strong gale</p><p>47-54(75-88)</p><p>Slight structural damage occurs;  shingles may blow away</p><p>10</p><p>Whole gale</p><p>55-63 (89-102)</p><p>Trees uprooted; or storm  considerable structural damage  occurs</p><p>11</p><p>Storm or  violent storm</p><p>64-72 (103-117)</p><p>Widespread  damage occurs</p><p>12</p><p>Hurricane</p><p>72 (&gt;117)</p><p>Widespread damage occurs</p><p>Wind Cave National Park National park, southwestern South  Dakota, U.S. Established in 1903 to preserve limestone caverns and  unspoiled prairie grassland in the Black Hills, it covers an area of 28,292  ac (11,449 ha). Its caves contain 83 mi (134 km) of explored passages  and have beautiful rock formations called boxwork, formed by calcite  deposition in unique patterns. The park is also a wildlife refuge.</p><p>wind chill Still-air temperature that would have the same cooling effect  on exposed skin as a given combination of temperature and wind speed.  As the wind speed increases, the wind chill equivalent temperature  decreases; e.g., an air temperature of 30 �F (�1.1 �C) with a wind speed  of 20 mph (32.2 kph) produces a wind chill of 17 �F (-8 �C). Wind chill  is often included in weather reports to describe how cold it feels. See  illustration on following page.</p><p>wind power Use of the energy in winds to produce power. Though  wind is irregular and spread out, it contains tremendous amounts of  energy. Sophisticated wind turbines have been developed to convert this  energy to electric power. The use of wind-energy systems grew consid�  erably in the 1980s and �90s. Germany today produces more wind energy  than any other country. Some 15,000 wind turbines are now in operation  in California.

It  contains many peaks above 12,000 ft (3,658 m); the highest is Gannett  Peak at 13,804 ft (4,207 m). The Oregon Trail ran through the historic  South Pass (7,743 ft, or 2,360 m). Parts of Bridger and Shoshone national  forests and Wind River Indian Reservation are in the range. The Wind  River flows from the eastern side into the Bighorn River; the Green River  rises on its western slopes.</p><p>wind shear Rate of change of wind velocity with distance perpendicu�  lar to the wind direction. A very narrow zone of abrupt velocity change  is known as a shear line. Wind shear is observed near the ground and in  jet streams, where it may be associated with clear-air turbulence. Vertical  wind shear is closely associated with the vertical flux of momentum, heat,  and water vapour.</p><p>wind tunnel Device for producing a controlled stream of air to study  the effects on objects such as aircraft moving through air or the effects of  moving air on models of stationary objects such as buildings. Applica�  tions of wind-tunnel research range from testing of airframes (the struc�  tures of aircraft and spacecraft) to research on the boundary layer,  turbulence, drag, and lift. Measurements of air pressure and other charac�  teristics at many points on the model yield information about how the  total wind load is distributed. In addition to testing the effects of wind on  aircraft and spacecraft, studies in wind tunnels have been used to solve  design problems in automobiles, boats, trains, bridges, and buildings.

March 21, 1862, Vienna, Aus�  tria) Austrian field marshal. He entered the Habsburg imperial army as an  officer (1804) and rose through the ranks to become military commander  for Bohemia (1840). In the Revolutions of 1848, he suppressed the Czech  rebels in Prague and crushed the insurrection in Vienna, where he was  noted for his harsh military rule. Appointed field marshal (1848), he occu�  pied Budapest in 1849 and drove the Hungarian rebels beyond the Tisza  River. Although he was given supreme command of all imperial troops  outside Italy, his gifts as a commander were mediocre, and differences  with his brother-in-law, the Habsburg prime minister, prince zu  Schwarzenberg, resulted in his recall (1849). Thereafter Windischgratz  retired to Bohemia.</p><p>windmill Machine for harnessing the energy of the wind using sails  mounted on a rotating shaft. The sails are mounted at an angle or are given  a slight twist, so that the force of wind against them has two components,  one of which, in the plane of the sails, causes rotation. Like waterwheels,  windmills were among the original prime movers that replaced human  beings as a source of power. Their most important traditional use was for  grinding grain, though in certain areas their use in land drainage and water  pumping was equally important. Windmill use became increasingly wide�  spread in Europe (particularly the Netherlands) from the 12th century to  the early 19th century, but thereafter slowly declined. Interest in wind�  mills for generating electric power revived in the 1970s. See also wind  POWER.</p><p>window Opening in the wall of a building for light and air, and some�  times for framing a view. Since early times, the openings have been filled  with stone, wooden, or iron grilles, with panes of glass or other translu�  cent material such as mica or, in East Asia, paper. A window in a verti�  cally sliding frame is called a sash window: a single-hung sash has only  one half that moves; in a double-hung sash, both parts slide. A casement  window swings open on hinges attached to the upright side of the frame.  Awning windows swing outward on hinges attached to the top of the  frame; hopper windows swing inward on hinges attached to the bottom  of the frame.

It was known first as �the Ferry� and later as Richmond</p><p>before it was renamed in 1836. With  its strategic location opposite  Detroit, it became an industrial cen�  tre, an important railway terminus,  and a busy port in Great Lakes ship�  ping.

Wine  may also be made from various fruits and plant parts. Though known by  the ancients, wine was not drunk in its matured form until the develop�  ment of the bottle and cork in the late 17th century. In wine manufacture,  grapes are crushed and strained, and the juice (called must) is sealed in  vats along with yeast ( Saccharomyees ellipsoideus ) and often sulfur diox�  ide, which suppresses wild yeasts and organisms. Fermentation continues  for several weeks, and then the wine is drawn off (�racked�) into wooden  barrels or other containers for a second fermentation (�aging�). It is clari�  fied and bottled before undergoing final maturation. Wines may be clas�  sified according to colour as red, rose (pink), or white; colour depends on  whether the skins of red grapes are allowed to ferment with the juice.  Wine taste is described as sweet or dry, sweet wines being high in sugar  content and dry wines containing little or no sugar. Sparkling wines, such  as champagne, contain suspended carbon dioxide, the result of bottling the  wine before fermentation is complete. Fortified wines, such as port and  sherry, contain added brandy. The leading wine-producing countries are  France, Italy, Spain, the U.S., Argentina, Germany, Australia, South  Africa, Portugal, and Romania.</p><p>Winfrey, Oprah (b.

Initially sensationalist, the enormously  popular show gradually took on an uplifting and therapeutic tone. In 1986  she also formed her own television production company, Harpo Produc�  tions. In 1996 she introduced �Oprah�s Book Club� to foster reading by  endorsing certain books. She appeared in the movies The Color Purple  (1985) and Beloved (1998).</p><p>wing In zoology, one of the paired structures certain animals use for  flying. Bat and bird wings are modifications of the vertebrate forelimb. In  birds, the fingers are reduced and the forearm is lengthened. The primary  flight feathers propel the bird forward, and the secondaries (on the upper  wing) provide lift. Bat wings consist of a membrane stretched over slen�  der, elongated arm and hand bones. Insect wings are folds of integument  (�skin�). Most insects have two pairs of wings; dipterans (flies) have only  one developed pair, and beetles have two but use only one for flying. The  two wings on a side usually move together, but dragonfly wings work  independently.</p><p>Winnebago \,wi-n3-'ba-go\ North American Indian people who live in  the Midwestern U.S., notably Iowa, Wisconsin, and Nebraska. Their lan�  guage belongs to the Siouan language family, and their name is derived  from a Fox name meaning �People of the Stinking Water.� They call  themselves Hochungra, meaning �People of the Big Speech [or Parent  Speech].� Before the 17th century, the Winnebago lived in what is now  eastern Wisconsin. By the early 19th century, as a result of their partici�  pation in the fur trade, they had expanded into southwestern Wisconsin  and northwestern Illinois. They lived in villages of dome-shaped wig�  wams; there they cultivated com, squash, beans, and tobacco and hunted  bison. Their major ceremony was the medicine dance, in which both men  and women participated. Membership in the 12 clans was determined by  the father, and the clans were important units in social life. The Win�  nebago were involved in the Black Hawk War of 1832, after which most  of the tribe was removed to other Midwestern states. At the turn of the  21st century they numbered some 12,000.</p><p>Winnemucca, Sarah Hopkins See Sarah Winnemucca Hopkins</p><p>Winnipeg City (pop., 2001: metro, area, 671,274), capital of Manitoba,  Canada.

Wisconsin is bordered by the western portion of  Lake Superior and the Upper Peninsula of Michigan to the north; Lake  Michigan to the east; Illinois to the south; and Minnesota and Iowa to the  west and southwest, with the upper Mississippi River acting as border between  these states and Wisconsin. With many unique landforms, including the  Door Peninsula between Lake Michigan and Green Bay, its northern area  has one of the greatest concentrations of lakes in the world. The Wisconsin  River crosses the state. Forests cover about 45% of it. Originally inhabited  by the Adena, or Mound Builders, the region was home to several different  Indian tribes, including the Ojibwa, Menominee, and Winnebago, when  Europeans arrived. The French explorer Jean Nicolet visited Wisconsin in  1634; the first permanent European settlement was established in 1717.  The area remained under French control until 1763, when France ceded it  to Great Britain after the French and Indian War. After the American Revo�  lution the region was ceded to the U.S. The American settlers dispossessed  the Indians of their land (see Black Hawk) and settled the region. It became  the Wisconsin Territory in 1836. It was admitted to the Union as the 30th  state in 1848. The Progressive movement (see Progressive Party) began in  Wisconsin c. 1900, resulting in the passage of legislation that made the  state a leader in social reform.

It attested his grants of  land to churches or laymen, consented to his issue of new laws, and helped  him deal with rebels and disaffected subjects. Its composition and time  of meeting were determined at the king�s pleasure.</p><p>witch hazel family Family Hamamelidaceae, comprising 23 genera  of shrubs and trees, native to tropical and warm temperate regions. The  six species of the genus Hamamelis include such ornamentals as witch  hazel, winter hazel, and Fothergilla, which are outstanding for their early  flowering and fall leaf colour. Members of the family are characterized  by simple leaves and by flowers with four or five petals and sepals each.  American, or common, witch hazel ( H. virginiana ) flowers in fall and  retains yellow, cuplike calyxes (collections of sepals) through the winter.  The common name refers to the forked twigs that were sometimes used  for water-witching, or dowsing to locate underground water. The fragrant  liniment witch hazel is made from the dried leaves and sometimes from  twigs and bark. Brilliant autumn leaf colour is an outstanding trait of  ironwood ( Parrotia persica). Another genus, Altingia, has seven species,  all Asian and all valued for their timber. A. excelsa is one of the largest  trees of the Asian tropics, sometimes reaching a height of 82 ft (25 m).</p><p>witchcraft and sorcery Use of alleged supernatural powers, usually  to control people or events. Sorcery is sometimes distinguished from  witchcraft in that sorcery may be practiced by anyone with the appropri�  ate knowledge, using charms, spells, or potions, whereas witchcraft is  considered to result from inherent mystical power and to be practiced by  invisible means. Modern witches, however, claim that their craft is  learned, and therefore another distinction between witchcraft and sorcery  is that sorcery is always used with evil intent. Controversies over witch�  craft and sorcery have been especially prevalent in close-knit communi�  ties experiencing decline or misfortune and embroiled in petty social  conflict and scapegoating. In ancient Greece, witchcraft was mentioned  as early as Homer (see Circe). The best-known sorceress in Classical times  was the legendary Medea. The Roman Horace describes two witches in  his Satires. The Bible contains several references to witches, notably the  Witch of Endor consulted by Saul (1 Samuel 28). The early Church  Fathers held that witchcraft was a delusion and denounced its practice. In  the Middle Ages, witchcraft was believed to involve demonic possession.  It was also associated with heresy and so came within the scope of the  Inquisition. In the witch-hunts of the 1 6th� 17 th centuries, European courts  frequently regarded witches and sorcerers alike as candidates for burning.  Although estimates of the number killed vary widely, it is likely that  between 40,000 and 60,000 people were executed and many more were  tortured and imprisoned during the witch-hunts. In the 20th century the  modern witchcraft movement, Wicca, was established and promoted  respect for nature and a pantheistic worldview. Belief in witchcraft is  apparent in traditional societies throughout the world. The Navajo protect  themselves against witches with sand or pollen paintings, and in African  societies people seek aid from medical doctors and witch doctors, the  former for treatment of the �external� causes of the illness and the latter  for the �internal�.

Ordained a Presbyterian minister (1745), he served in Scottish parishes  until 1768, when he was sent to North America to become president of the  College of New Jersey (later Princeton University). As president, he  expanded the curriculum and increased enrollment. A supporter of colo�  nists� rights, he was a member of the local Committee of Correspondence  (1775-76) and the Continental Congress (1776-79, 1780-82); he was the  only clergyman to sign the Declaration of Independence.

He entered the imperial admin�  istrative service in 1871 and served as minister of finance (1892-1903).  He improved communications, promoted construction of the Trans-  Siberian Railway, and planned to modernize the Russian Empire. He rep�  resented Russia in the negotiations that ended the Russo-Japanese War.  Although opposed to constitutionalism, he persuaded Tsar Nicholas II to  issue the October Manifesto in 1905 and was appointed the first consti�  tutional premier. He organized the repression of all the forces of disrup�  tion in 1905-06�e.g., the St. Petersburg Soviet, or workers� council, the  troop mutinies in the Far East, strikes in South Russia, and peasant upris�  ings in the Baltic provinces�and he concluded arrangements with Euro�  pean bankers for a series of loans that restored Russian finances. In 1906  the tsar, favouring a more conservative regime, replaced him with Pyotr  Stolypin. He never returned to office, and in 1914-15 he vainly opposed  Russian entry into World War I and was sympathetic to peace feelers put  out by the German government through Witte�s own German banker.</p><p>Wittelsbach Vvi-tols-.bakX, house of German noble family that ruled  in Bavaria from the 12th to the 20th century. In 1124 Otto V, count of  Scheyem (d. 1155), moved the family residence to the castle of Wittels�  bach and took its name. In 1180 his son Otto VI became Otto I, duke of  Bavaria. In 1214 Otto II obtained the Palatinate of the Rhine. A descen�  dant, Louis IV, as Holy Roman emperor, divided the lands and granted the  Palatinate to his nephew, Rupert, who obtained the title of elector (r.  1353-90). Several divisions of ducal Bavaria were reunited under Albert  IV (d. 1508). The Bavarian dukes became electors from 1623, and the last  direct line died out in 1777. The Palatine branch united with Bavaria in  1799 under Duke Maximilian IV Joseph, who became king of Bavaria  (1806) as Maximilian I. His descendants (including Louis I and Louis II) were  kings until the abdication of Louis III in 1918.</p><p>Wittgenstein Vvit-gon-.shtlnN, Ludwig (Josef Johann) (b. April  26, 1889, Vienna�d. April 29, 1951, Cambridge, Cambridgeshire, Eng.)  Austrian-born English philosopher, regarded by many as the greatest phi�  losopher of the 20th century. He was bom into an immensely wealthy and  cultivated family. In 1908 he went to Manchester, Eng., to study aero�  nautics. He soon developed an obsessive interest in the philosophy of  logic and mathematics, and in 1911 he went to Cambridge to study logic  with Bertrand Russell. Within a year he had learned all Russell had to teach;  he then went to Norway, where he worked on logic in isolation in a  wooden hut he built by the side of a fjord. There he developed in embryo  what became known as the �picture theory� of meaning, a central tenet  of which is that a proposition can express a fact by virtue of sharing with  it a common structure, or �logical form.� When World War I broke out  he joined the Austrian army, winning several decorations for bravery  while serving on the Russian front. During the war he worked on a manu�  script that was later published as Tractatus Logico-Philosophicus (1922).  Believing that he had solved all the major problems of philosophy, he  abandoned the subject after the war and spent the next 10 years as a  schoolteacher and doing other odd jobs in a remote Austrian village.  Meanwhile, the Tractatus had attracted the attention of philosophers in  Cambridge and Vienna, including those of the Vienna Circle of logical  positivists (see logical positivism), some of whose meetings Wittgenstein  was persuaded to join. He returned to Cambridge in 1929. During the early  1930s his ideas changed rapidly, and he gradually abandoned the doc�  trines of the Tractatus', indeed, he began to conceive of philosophy in  radically different terms, as not the construction of theories designed to  answer philosophical questions but as the activity of clearing up concep�  tual confusions arising from inattention to or misunderstandings of ordi�  nary uses of language. What became known as the works of the �later  Wittgenstein��including Remarks on the Foundations of Mathematics  (1956), Philosophical Grammar (1974), Philosophical Remarks (1975),  and especially Philosophical Investigations (1953)�can be considered  attempts to refine and definitively express this new approach. Though he  worked with fierce energy and wrote prodigiously, he would allow none  of his work from this period to be published in his lifetime. In 1939 he  was appointed to the chair in philosophy at Cambridge previously held  by G.E. Moore. Disliking professional philosophy, he resigned the post</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2070 I Witz &#x25BA; Wolfe</p><p>in 1947 to live in seclusion in Ireland and then with various friends.

He had to defeat rivals, including his cousin Vytautas,  in order to secure his rule in Lithuania. He married the Polish queen Jad-  wiga (1386) after agreeing to Christianize Lithuania and unite it with  Poland. He regained Ruthenia from Hungary (1387) and made the prince  of Moldavia his vassal.

He lived for long periods in the U.S. and France after 1909, and  he settled in the U.S. after World War II. He is best known as the creator  of the character of the young bachelor Bertie Wooster and his effortlessly  superior manservant, Jeeves, who appeared in comic stories and novels  from �Extricating Young Gussie� (1915) to Much Obliged, Jeeves (1971).  Wodehouse wrote more than 90 books and 20 film scripts and collabo�  rated on many plays and musical comedies, writing lyrics for Jerome Kern  {Leave It to Jane, 1917; Show Boat , 1927), George Gershwin {Oh, Kay!,  1926), and others.</p><p>Wolcott, Oliver (b.

The gray, or timber, wolf  {Canis lupus ) is the ancestor of all domestic dogs. It once had the largest  distribution of any mammal except human beings, but it is now found  primarily in Canada, Alaska, the Balkans, and Russia. Wolves are intel�  ligent and social. Their primary prey are deer, moose, and caribou, though  they feed on many smaller animals as well. Because wolves have killed  livestock, they have been persecuted by farmers and ranchers. A male gray  wolf may be 7 ft (2 m) long and weigh up to 175 lb (80 kg); it is the  largest living wild canid. Gray wolves live in hierarchical packs whose  territories cover at least 38 sq mi (100 sq km) and hunt mostly at night.  The much smaller red wolf (C. rufus), once widespread in the south-  central U.S., has been bred in captivity and reintroduced. The Abyssinian  wolf (C. simensis) of Ethiopia was formerly considered a jackal. See also  DIRE WOLF.</p><p>Wolf \'volf,\ English Vwulf\, Christa orig.

He entered  the Vienna Conservatory at age 15, but, as a rabid Wagnerian, he lost  patience with his teachers� conservatism and soon left. By age 18 he  probably had contracted the syphilis that would make him mentally  unstable and eventually kill him. His volatile personality made it difficult  for him to keep private students. As a critic (1884-87), he attracted atten�  tion for his vituperative comments. His productivity came in bursts; in  1888-89 he produced the remarkable songs of the Morike Lieder, the  Eichendorff Lieder, the Goethe Lieder, and much of the Spanish  Songbook �more than half his total output. After beginning the Italian  Songbook in 1891, he wrote nothing for three years, then quickly com�  posed the opera Der Corregidor (1896) and finished the Italian Songbook  (1896). In 1897 he suffered a complete breakdown, and he thereafter lived  largely in an asylum.</p><p>wolf spider Name that originally referred to a species of southern  European spider {Lycosa tarentula ) but now refers to more than 175 spi�  der species (family Lycosidae) found in North America, Europe, and north  of the Arctic Circle.

On Henry�s recommendation, the pope made Wolsey successively bishop  of Lincoln (1514), archbishop of York (1514), cardinal (1515), and papal  legate (1518). In 1515 Henry appointed him lord chancellor of England,  which added to his power and wealth. Wolsey sought to bring peace to  Europe, but in 1521 he allied with Emperor Charles V against France.  Although he introduced judicial and monastic reforms, he became  unpopular for raising taxes. In 1529 he failed to persuade the pope to grant  Henry an annulment of his marriage to Catherine of Aragon, for which  he soon lost favour and was stripped of his offices except the archbish�  opric of York.

Women�s voting rights became an issue in the 19th century,  especially in Britain and the U.S. In the U.S. the woman suffrage move�  ment arose from the antislavery movement (see abolitionism) and from the  advocacy of figures such as Lucretia Mon and Elizabeth Cady Stanton, who  believed that equality should extend to both women and African Ameri�  cans. They organized the Seneca Falls Convention (1848), which issued a  declaration calling for woman suffrage and for the right of women to edu�  cational and employment opportunities. In 1850 Lucy Stone held the move�  ment�s first national convention. Stanton and Susan B. Anthony formed  the National Woman Suffrage Association in 1869 to secure an amend�  ment to the Constitution granting women the right to vote, while Stone  founded the American Woman Suffrage Association to seek similar  amendments to state constitutions; in 1890 the two organizations merged  as the National American Woman Suffrage Association. Following Wyo�  ming�s lead in 1890, states began adopting such amendments; by 1918  women had won suffrage in 15 states. After a woman suffrage amend�  ment was passed by Congress, a vigorous campaign brought ratification,  and in August 1919 the 19th Amendment became part of the Constitution.  In Britain the first woman suffrage committee was formed in Manchester  in 1865. In the 1870s suffragists submitted petitions bearing nearly three  million signatures. Despite growing support, suffrage bills were continu�  ally defeated; in frustration, some suffragists became militant activists  under the leadership of Emmeline and Christabel Pankhurst. Parliament  finally passed the Representation of the People Act in 1918, by which time  women had already won voting rights in New Zealand (1893), Australia  (1902), Finland (1906), Norway (1913), the Soviet Union (1917), Poland  (1918), Sweden (1919), Germany (1919), and Ireland (1922).

After the war  the government requested former servicewomen to reenlist to meet the  staffing needs of army hospitals and administrative centres. The WAC  became part of the regular army with the passage of the 1948 Women�s  Armed Services Integration Act. The WAC remained a separate unit of the  U.S. Army until 1978, when male and female forces were integrated.</p><p>women's movement Diverse social movement, largely based in the  U.S., seeking equal rights and opportunities for women in their economic  activities, personal lives, and politics. It is recognized as the �second  wave� of the larger feminist movement. While first-wave feminism of the  19th and early 20th centuries focused on women�s legal rights, such as  the right to vote, the second-wave feminism of the �women�s movement�  peaked in the 1960s and �70s and touched on every area of women�s  experience�including family, sexuality, and work. A variety of U.S.  women�s groups, including the National Organization for Women, sought  to overturn laws that enforced discrimination in matters such as contract  and property rights and employment and pay. The movement also sought  to broaden women�s self-awareness and challenge traditional stereotypes  of women as passive, dependent, or irrational. An effort in the 1970s to  pass the Equal Rights Amendment failed, but its aims had been largely  achieved by other means by the end of the 20th century.</p><p>Wonder, Stevie orig.

It is the principal strengthening  tissue found in the stems and roots of trees and shrubs. Wood forms around  a central core (pith) in a series of concentric layers called growth rings.  A cross section of wood shows the distinction between heartwood and  sapwood. Heartwood, the central portion, is darker and composed of  xylem cells that are no longer active in the life processes of the tree. Sap-  wood, the lighter area surrounding the heartwood, contains actively con�  ducting xylem cells. Wood is one of the most abundant and versatile  natural materials on earth, and unlike coal, ores, and petroleum, is renew�  able with proper care. The most widely used woods come from two groups  of trees: the conifers, or softwoods (e.g., pine, spruce, fir), and the broad-  leaves, or hardwoods (e.g., oak, walnut, maple). Trees classified as hard�  woods are not necessarily harder than softwoods (e.g., balsa, a hardwood,  is one of the softest woods). Density and moisture content affect the  strength of wood; in addition to load-bearing strength, other variable fac�  tors often tested include elasticity and toughness. Wood is insulating to  heat and electricity and has desirable acoustical properties. Some identi�  fying physical characteristics of wood include colour, odour, texture, and  grain (the direction of the wood fibres). Some 10,000 different wood  products are commercially available, ranging from lumber and plywood  to paper, from fine furniture to toothpicks. Chemically derived products  from wood and wood residues include cellophane, charcoal, dyestuffs,  explosives, lacquers, and turpentine. Wood is also used for fuel in many  parts of the world.</p><p>Cross section of a tree trunk. Wood is secondary xylem produced by growth of the  vascular cambium tissue. Sapwood is xylem that conveys water and dissolved min�  erals from the roots to the rest of the tree. The darker heartwood is older xylem that  has been infiltrated by gums and resins and has lost its ability to conduct water.  Each growth layer is distinguished by earlywood (springwood), composed of large  thin-walled cells produced during the spring when water is usually abundant, and  the denser latewood (summerwood), composed of small cells with thick walls.  Growth rings vary in width as a result of differing climatic conditions; in temperate  climates, a ring is equivalent to one year's growth. Certain conducting cells form  rays that carry water and dissolved substances radially across the xylem. Bark com�  prises the tissues outside the vascular cambium, including secondary phloem (which  transports food made in the leaves to the rest of the tree), cork-producing cells (cork  cambium), and cork cells. The outer bark, composed of dead tissue, protects the  inner region from injury, disease, and desiccation.</p><p>� MERRIAM-WEBSTER INC.</p><p>Wood, Grant (b. Feb. 13, 1892, near Anamosa, Iowa, U.S.�d. Feb.  12, 1942, Iowa City, Iowa) U.S. painter. He was trained as a craftsman  and designer as well as a painter. On a visit to Germany in 1928, he was  strongly influenced by the sharp detail of 15th-century German and Flem�  ish paintings, and he soon abandoned his Impressionist manner for the  detailed, realistic manner for which he is known. His American Gothic  caused a sensation when exhibited in 1930. A telling portrait of the sober,  hardworking Midwestern farmer, it has become one of the best-known  icons of U.S. art, though it is often misinterpreted: the woman is not the  man�s wife but rather the unmarried daughter designated to stay on the  farm to assist her widowed father.</p><p>Common wombat (Vombatus ursinus).</p><p>WARREN GARST-TOM STACK AND ASSOCIATES</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Wood &#x25BA; Woodhull I 2073</p><p>Wood, Leonard (b.

Its most prominent  members were Ralph Wood (1715-72), his brother Aaron (1717�85), and  his son Ralph, Jr. (1748-95). Ralph, Jr., was related through his mother  to Josiah Wedgwood, and the two names were often linked professionally.  The elder Ralph became famous for his extremely well-modeled figures  with coloured glazes, and he is credited with introducing the Toby mug.  Ralph, Jr., produced a variety of figures, colouring them with enamel  rather than glazes, and supplied some of them to Wedgwood. Aaron�s son  William (1746-1808) was employed as a modeler by Wedgwood. His  brilliant brother Enoch (1759-1840) apprenticed with Wedgwood but by  1783 was established as an independent potter in partnership with his  cousin Ralph, Jr. In 1818 he continued his firm as Enoch Wood &amp; Sons.

With eyes set far back on the head, a woodcock has a  360� field of vision. The bufify-brown, mottled plumage provides camou�  flage. A solitary bird, most active at dusk, it drums its feet to coax earth�  worms to the surface and then extracts them with its long, forceps-like  bill; it may eat twice its weight in worms each day. The female Ameri�  can woodcock (Scolopax, or Philohela, minor) is about 11 in. (28 cm)  long; the male is slightly smaller. The male�s striking courtship display  includes a long, repeated spiraling and dropping sequence. Woodcocks  have been popular game birds.</p><p>woodcut Design printed from a plank of wood incised parallel to the  vertical axis of the wood�s grain. One of the oldest methods of making  prints, it was used in China to decorate textiles from the 5th century.  Printing from wood blocks on textiles was known in Europe from the early  14th century but developed little until paper began to be manufactured in  France and Germany at the end of the 14th century. In the early 15th cen�  tury, religious images and playing cards were first made from wood  blocks. Black-line woodcut reached its greatest perfection in the 16th  century with Albrecht Durer and his followers. In the late 19th and early  20th centuries, artists such as Edvard Munch, Paul Gauguin, and the Ger�  man Expressionists rediscovered the expressive potential of woodcuts.

After Vic�  toria�s marriage (1853) to Canning Woodhull ended in 1864, the sisters  opened a successful brokerage firm in New York. They founded Woodhull  and Claflin�s Weekly (1870), which advocated equal rights for women, a  single standard of morality for both sexes, and free love. A splinter group  of radical suffragists formed a political party in 1872 and nominated  Woodhull for president with Frederick Douglass as vice president. In 1872  the sisters published the first English translation of the Communist Mani�  festo. For printing news of an alleged adulterous affair by Henry Ward  Beecher, they were charged with libel but acquitted (1873). They moved  to England (1877), where they lectured, worked for charities, and mar�  ried wealthy Englishmen.

Wool is readied by wash�  ing (lanolin is the by-product), carding, sometimes combing, then spin�  ning. Coarser than such textile fibres as cotton, linen, silk, and rayon, wool  is resilient after limited stretching or compression, so fabrics and garments  made from wool tend to retain shape, drape well, and resist wrinkling.  Wool is warm and lightweight and takes dyes well. Woolen yarns, usu�  ally made from shorter fibres, are thick and full and are used for such  items as tweed fabrics and blankets. Worsteds usually are made from  longer fibres.</p><p>Woolf Vwulf\, (Adeline) Virginia orig. Adeline Virginia  Stephen (b. Jan. 25, 1882, London, Eng.�d. March 28, 1941, near  Rodmell, Sussex) British novelist and critic. Daughter of Leslie Stephen,  she and her sister became the early nucleus of the Bloomsbury group. She  married Leonard Woolf in 1912; in 1917 they founded the Hogarth Press.  Her best novels�including Mrs. Dalloway (1925) and To the Lighthouse  (1927)�are experimental; in them she examines the human experience  of time, the indefinability of character, and external circumstances as they  impinge on consciousness. Orlando (1928) is a historical fantasy about a  single character who experiences England from the Elizabethan era to the  early 20th century, and The Waves (1931), perhaps her most radically  experimental work, uses interior monologue and recurring images to trace  the inner lives of six characters. Such works confirmed her place among  the major figures of literary modernism. Her best critical studies are col�  lected in The Common Reader (1925, 1932). Her long essay A Room of  One�s Own (1929) addressed the status of women, and women artists in  particular. Her other novels include Jacob�s Room (1922), The Years  (1937), and Between the Acts (1941). She also wrote a biography of Roger  Fry. Her health and mental stability were delicate throughout her life; in  a recurrence of mental illness, she drowned herself.

Oliver Cromwell and his Parliamentarian army routed  Charles II and his Scottish army in the Battle of Worcester, effecting an end  to the English Civil Wars. In 1751 John Wall founded the porcelain industry  for which the town became famous, and in 1838 the condiment known as  Worcestershire sauce was introduced there by Lea &amp; Perrins. The town�s  noted cathedral (11th-14th century) contains the tombs of King John and  Prince Arthur, the eldest son of Henry VII. Cathedral Grammar School and  Royal Grammar School were founded in the 16th century.</p><p>word processing Preparation of textual documents on computer. A  word-processing system typically consists simply of a personal computer  linked to a computer printer, but it may instead employ a terminal linked  to a mainframe computer. Word processing differs from typewriter typing  in numerous ways.

Jan van Wynkyn (b.</p><p>Alsace�d. 1534/35) Alsatian-born British printer. He was employed at  William Caxton�s press from its founding in 1476 until Caxton�s death,  when he took over the concern. Unlike Caxton and many other contem�  porary printers, he did not edit or translate. An astute businessman, he  published at least 600 titles after 1501, and he was the first printer in  England to use italic type (1524).</p></section><section><p>Wordsworth, Dorothy (b. Dec. 25, 1771, Cockermouth, Cumber�  land, Eng.�d. Jan. 25, 1855, Rydal Mount, Westmorland) English writer.  An inspiring influence on her brother William Wordsworth, she lived with  him from 1795 onward. Her Alfoxden Journal 1798 (1897)�from the  period when he and Samuel Taylor Coleridge produced Lyrical Ballads  (1798)�and Grasmere Journals 1800-03 (1897) are intimate records of  their lives. Both are appreciated for their imaginative descriptions of  nature, their perfection of style, and their revelation of her personality as  well as for the light they throw on her brother. In 1829 severe illness left  her an invalid, and her mind was clouded in her last 20 years.</p><p>Wordsworth, William (b. April 7, 1770, Cockermouth, Cumberland,  Eng.�d. April 23, 1850, Rydal Mount, Westmorland) English poet.  Orphaned at age 13, Wordsworth attended Cambridge University, but he</p><p>remained rootless and virtually penniless until 1795, when a legacy made  possible a reunion with his sister Dorothy Wordsworth. He became  friends with Samuel Taylor Coleridge, with whom he wrote Lyrical Ballads  (1798), the collection often considered to have launched the English  Romantic movement. Wordsworth�s contributions include �Tintern  Abbey� and many lyrics controversial for their common, everyday lan�  guage. About 1798 he began writing The Prelude (1850), the epic auto�  biographical poem that would absorb him intermittently for the next 40  years. His second verse collection. Poems, in Two Volumes (1807),  includes many of the rest of his finest works, including �Ode: Intimations  of Immortality.� His poetry is perhaps most original in its vision of the  organic relation between man and the natural world, a vision that culmi�  nated in the sweeping metaphor of nature as emblematic of the mind of  God. The most memorable poems of his middle and late years were often  cast in elegaic mode; few match the best of his earlier works. By the time  he became widely appreciated by the critics and the public, his poetry had  lost much of its force and his radical politics had yielded to conservatism.  In 1843 he became England�s poet laureate. He is regarded as the central  figure in the initiation of English Romanticism.</p><p>work In economics and sociology, the activities and labour necessary  for the survival of society. As early as 40,000 bc, hunters worked in groups  to track and kill animals, while younger or weaker members of the tribe  gathered food. When agriculture replaced hunting and gathering, the  resulting surplus of food allowed early societies to develop and some of  its members to pursue crafts such as pottery, weaving, and metallurgy.  Historically, rigid social hierarchies caused nobles, clergy, merchants, arti�  sans, and peasants to pursue occupations defined largely by hereditary  social class. Craft guilds, influential in the economic development of medi�  eval Europe, limited the supply of labour in each profession and controlled  production. The establishment of towns led to the creation of new occu�  pations in commerce, law, medicine, and defense. The coming of the  Industrial Revolution, spurred by technological advances such as steam  power, changed working life profoundly. Factories divided the work once  done by a single craftsman into a number of distinct tasks performed by  unskilled or semiskilled workers (see division of labour). Manufacturing  firms grew larger in the 19th century as standardized parts and machine  tools came into use, and ever-more-specialized positions for managers,  supervisors, accountants, engineers, technicians, and salesmen became  necessary. The trend toward specialization continued into the 21st cen�  tury, giving rise to a number of disciplines concerned with the manage�  ment and design of work, including production management, industrial  relations, personnel administration, and systems engineering. By the turn of  the 21st century, automation and technology had spurred tremendous  growth in service industries.</p><p>work In physics, the measure of energy transfer that occurs when an  object is moved over a distance by an external force, some component of  which is applied in the direction of displacement. For a constant force,  work W is equal to the magnitude of the force F times the displacement  d of the object, or W = Fd. Work is also done by compressing a gas, by  rotating a shaft, and by causing invisible motions of particles within a  body by an external magnetic force. No work is accomplished by simply  holding a heavy stationary object, because there is no transfer of energy  and no displacement. Work done on a body is equal to the increase in  energy of the body. Work is expressed in units called joules (J). One joule  is equivalent to the energy transferred when a force of one newton is  applied over a distance of one metre.</p><p>workers' compensation Program through which employers bear  some of the cost of their employees� work-related injuries and occupa�  tional illnesses or disabilities. It was first introduced in Germany in 1884.  In Britain and the U.S. in the late 19th century, there was a movement to  secure the right of injured workers to compensation and to improve work�  ing conditions through court decisions, employer liability statutes, and  safety codes. By the mid-20th century most countries in the world had  adopted some sort of workers� compensation. Some systems take the form  of compulsory social insurance; in others the employer is legally required  to provide certain benefits, but insurance is voluntary. The system of  workers� compensation serves as an economic incentive for employers to  prevent accidents and illness among employees, since liability for medi�  cal costs and the income lost by placing workers in hazardous environ�  ments can easily exceed the costs of establishing safe working conditions.</p><p>Workers' Opposition (1920-21) Group within the Soviet Union�s  Communist Party that championed workers� rights and trade-union control</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2076 I working dog &#x25BA; World Trade Center</p><p>over industry. It was formed in 1919 to resist the central party�s increas�  ing control over local party units and trade unions. In 1920 it objected to  Leon Trotsky�s plan to transform trade unions into state organs. Led by  Aleksandra Kollontay and others, the group insisted that the unions, as  true representatives of the proletariat, should control the national  economy. At the 10th Party Congress (1921), its platform was rejected  and it was ordered to disperse.</p><p>working dog Any of various breeds of dog bred as guard, herding,  draft, or rescue animals. Breeds range from medium to large, but all are  sturdy and muscular, intelligent and loyal. Guard breeds include the Akita,  boxer, bullmastiff, Doberman pinscher, giant and standard schnauzers, Great  Dane, mastiff, and Rottweiler. Livestock guard breeds include the Great  Pyrenees, komondor (Hungary), kuvasz (Tibet), and Pyrenean mountain  dogs (Britain). Herding dogs include the German shepherd, Shetland sheep�  dog, and Welsh corgi. Breeds developed for hauling and rescue work  include the Bernese mountain dog, Portuguese water dog, Newfoundland,  St. Bernard, and sled dog.</p><p>Workingmen's Party First labour-oriented U.S. political party. It  was formed in Philadelphia (1828) and New York (1829) by craftsmen,  skilled journeymen, and reformers who demanded a 10-hour workday,  free public education, abolition of debtor imprisonment, and an end to  competition from prison contract labour. Leaders included Thomas Skid�  more, Fanny Wright, Robert Dale Owen, and George H. Evans, who estab�  lished the Working Man�s Advocate, the first labour newspaper, in 1829.  Factional disputes split the party in the 1830s, and many in New York  joined the reform Locofoco Party.</p><p>Works Progress Administration See WPA</p><p>workstation Computer intended for use by one person, but with a much  faster processor and more memory than an ordinary personal computer.  Workstations are designed for powerful business applications that do large  numbers of calculations or require high-speed graphical displays; the  requirements of CAD/CAM systems were one reason for their initial  development. Because of their need for computing power, they are often  based on RISC processors and generally use UNIX as their operating sys�  tem. An early workstation was introduced in 1987 by Sun Microsystems;  workstations introduced in 1988 from Apollo, Ardent, and Stellar were  aimed at 3D graphics applications. The term workstation is also sometimes  used to mean a personal computer connected to a mainframe computer, to  distinguish it from �dumb� display terminals with limited applications.</p><p>World Bank Specialized agency of the United Nations system, estab�  lished at the Bretton Woods Conference for postwar reconstruction. It is  the principal international development institution. Its five divisions are  the International Bank for Reconstruction and Development (IBRD; its main  component), the International Development Association (IDA), the Inter�  national Finance Corporation (IFC), the Multilateral Investment Guaran�  tee Agency (MIGA), and the International Center for Settlement of  Investment Disputes (ICSID). The IDA (founded 1960) makes interest-  free loans to the bank�s poorest member countries. The IFC (founded  1956) lends to private businesses in developing countries. The MIGA  (founded 1985) supports national and private agencies that encourage for�  eign direct investment by offering insurance against noncommercial risks.  The ICSID (founded 1966) was developed to relieve the IBRD of the bur�  den of settling investment disputes. See also International Monetary Fund.</p><p>World Council of Churches (WCC) Christian ecumenical organi�  zation founded in 1948 in Amsterdam. It functions as a forum for Prot�  estant and Eastern Orthodox denominations, which cooperate through the  WCC on a variety of undertakings and explore doctrinal similarities and  differences. It grew out of two post-World War I ecumenical efforts, the  Life and Work Movement (which concentrated on practical activities) and  the Faith and Order Movement (which focused on doctrinal issues and  the possibility of reunion). The impetus for these two organizations sprang  from the International Missionary Conference in Edinburgh in 1910, the  first such cooperative effort since the Reformation. The Roman Catholic  church, though not a member of the WCC, sends representatives to its  conferences. The more fundamentalist Protestant denominations have also  refused to join.</p><p>World Court See International Court of Justice</p><p>World Cup Major international football (soccer) competition. The tour�  nament brings together 32 qualifying national teams from around the  world, culminating in a match between the two top teams. It has been</p><p>held every fourth year since 1930 (except during World War II). Followed  and watched by billions of people worldwide, it has by far the greatest  audience of any single sporting event in the world. Several competitions  in other sports also use the name �world cup.�</p><p>World Food Programme (WFP) Organization established in 1961  by the United Nations to help alleviate world hunger. The world�s largest  food-aid organization (providing food aid to some 75 million people annu�  ally), the WFP aims to assist the approximately 15% of the world�s popu�  lation that is hungry. Its Food-for-Life program aids victims of both  natural and man-made disasters by collecting and transporting food to  crisis areas. Contributions of commodities, cash, and services (primarily  shipping) help beneficiaries to maintain balanced diets. Its Food-for-  Growth programs are directed at vulnerable groups�including children,  pregnant and nursing women, and the elderly�and its Food-for-Work  program encourages self-reliance by providing food in return for labour.  Its headquarters are in Rome.</p><p>World Health Organization (WHO) Public-health agency of the  UN, established in Geneva in 1948 to succeed two earlier agencies. Its  mandate is to promote �the highest possible level of health� in all peoples.  Its work falls into three categories. It provides a clearinghouse for infor�  mation on the latest developments in disease and health care and estab�  lishes international sanitary standards and quarantine measures. It  sponsors measures for the control of epidemic and endemic disease  (including immunization campaigns and assistance in providing sources  of pure water). Finally, it encourages the strengthening of public-health  programs in member nations. Its greatest success to date has been the  worldwide eradication of smallpox (1980).</p><p>World Heritage site Any of various areas or objects designated as  having �outstanding universal value� under the Convention Concerning  the Protection of the World Cultural and Natural Heritage. This conven�  tion, adopted by UNESCO in 1972, provides for international coopera�  tion in preserving and protecting cultural and natural treasures throughout  the world. Each site on the list is under strict legal protection by the gov�  ernment of the nation in which it is situated. Among the cultural sites are  many of the world�s most famous buildings. The ratio of cultural to natu�  ral sites on the list is roughly three to one. See table opposite.</p><p>world music Musical genre incorporating diverse styles from Africa,  eastern Europe, Asia, South and Central America, the Caribbean, and  nonmainstream Western folk sources. The term was first coined largely  in response to the sudden increase of recordings in non-English languages  that were released in Great Britain and the United States in the 1980s, but  by the early 1990s world music had become a bona fide musical genre  and counterpoint to the increasingly synthetic sounds of Western pop  music. Initially, African popular music and world music were virtually  synonymous, and the genre�s biggest stars included the Nigerians King  Sunny Ade and Fela Anikulapo Kuti and the Senegalese Youssou N�Dour.  Moreover, one of its earliest advocates was the Cameroonian-born  Frenchman Francis Bebey. By the 21st century world music encompassed  everything from Pakistani singer Nusrat Fateh Ali Khan and the pop-  flamenco of the French group the Gipsy Kings to �ambient-global�  projects that merged so-called ethnic voice samples with state-of-the-art  rhythm programming.</p><p>World Series Annual championship of U.S. major league baseball,  played between the top team of the American League (AL) and that of the  National League (NL). First held in 1903, it was canceled the following  year after the New York Giants (NL) refused to play Boston (AL). The  series resumed in 1905 and continued annually until a players� strike in  1994 forced its cancellation that year. A seven-game series has been stan�  dard since 1922.</p><p>World Trade Center Complex formerly consisting of seven buildings  around a central plaza, near the southern tip of Manhattan. Its huge twin  towers (completed 1970-72) were designed by Minoru Yamasaki (1912�  86). At 1,368 ft (417 m) and 1,362 ft (415 m) tall, they were the world�s  tallest buildings until surpassed in 1973 by the Sears Tower in Chicago.  The towers were notable for the relationship of their simple, light embel�  lishment to their underlying structure. In 1993 a bomb planted by terror�  ists exploded in the underground garage, killing several people and  injuring some 1,000. A much more massive attack occurred on Sept. 11,  2001, when first One World Trade Center and then Two World Trade  Center were struck by hijacked commercial airliners that were deliber�  ately flown into them.

It was created in 1995 to  replace the General Agreement on Tariffs and Trade (GATT). Like its prede�  cessor, it aims to lower trade barriers and encourage multilateral trade. It  monitors members� adherence to GATT agreements and negotiates and  implements new agreements. Critics of the WTO, including many oppo�  nents of economic globalization, have charged that it undermines national  sovereignty by promoting the interests of large multinational corporations  and that the trade liberalization it encourages leads to environmental dam�  age and declining living standards for low-skilled workers in developing  countries. By the early 21st century, the WTO had more than 145 members.</p><p>world tree Centre of the world, a widespread motif in myths and folk�  tales among various peoples, especially in Asia, Australia, and North  America. There are two main forms. In the vertical tradition, the tree  extends between and connects earth, heaven, and the underworld; oracles,  judgments, and other prophetic activities are performed at its base. In the  horizontal tradition, the tree is planted at the centre of the world and is  protected by supernatural guardians; it is the source of terrestrial fertility  and life.</p><p>World War I or First World War (1914-18) International conflict  between the Central Powers �Germany, Austria-Hungary, and Turkey�  and the Allied Powers �mainly France, Britain, Russia, Italy, Japan, and  (from 1917) the U.S. After a Serbian nationalist assassinated Archduke  Francis Ferdinand of Austria in June 1914, a chain of threats and mobili�  zations resulted in a general war between the antagonists by mid-August.  Prepared to fight a war on two fronts, based on the Scfiueffen Plan, Ger�  many first swept through neutral Belgium and invaded France. After the  First Battle of the Marne (1914), the Allied defensive lines were stabilized  in France, and a war of attrition began. Fought from lines of trenches and  supported by modern artillery and machine guns, infantry assaults gained  little ground and were enormously costly in human life, especially at the  Battles of Verdun and the Somme (1916). On the Eastern Front, Russian  forces initially drove deep into East Prussia and German Poland (1914)  but were stopped by German and Austrian forces at the Battle of Tannen-  berg and forced back into Russia (1915). After several offensives, the  Russian army failed to break through the German defensive lines. Rus�  sia�s poor performance and enormous losses caused widespread domes�  tic discontent that led to the Russian Revolution of 1917. Other fronts in  the war included the Dardanelles Campaign, in which British and Domin�  ion forces were unsuccessful against Turkey; the Caucasus and Iran (Per�  sia), where Russia fought Turkey; Mesopotamia and Egypt, where British  forces fought the Turks; and northern Italy, where Italian and Austrian  troops fought the costly Battles of the Isonzo. At sea, the German and Brit�  ish fleets fought the inconclusive Battle of Jutland, and Germany�s use of</p><p>the submarine against neutral shipping eventually brought the U.S. into  the war in 1917. Though Russia�s armistice with Germany in December  1917 released German troops to fight on the Western Front, the Allies  were reinforced by U.S. troops in early 1918. Germany�s unsuccessful  offensive in the Second Battle of the Marne was countered by the Allies�  steady advance, which recovered most of France and Belgium by Octo�  ber 1918 and led to the November Armistice. Total casualties were esti�  mated at 10 million dead, 21 million wounded, and 7.7 million missing  or imprisoned.

Political and economic instability in Germany, combined with bit�  terness over its defeat in World War I and the harsh conditions of the  Treaty of Versailles, allowed Adolf Hitler and the Nazi Party to rise to  power. In the mid-1930s Hitler began secretly to rearm Germany, in vio�  lation of the treaty. He signed alliances with Italy and Japan to oppose the  Soviet Union and intervened in the Spanish Civil War in the name of anti�  communism. Capitalizing on the reluctance of other European powers to  oppose him by force, he sent troops to occupy Austria in 1938 (see  Anschluss) and to annex Czechoslovakia in 1939. After signing the  German-Soviet Nonaggression Pact, Germany invaded Poland on Sept. 1,  1939. Two days later France and Britain declared war on Germany.  Poland�s defeat was followed by a period of military inactivity on the  Western Front (see Phony War). At sea Germany conducted a damaging  submarine campaign by U-BOAT against merchant shipping bound for Brit�  ain. By early 1940 the Soviet Union had divided Poland with Germany,  occupied the Baltic states, and subdued Finland in the Russo-Finnish War.  In April 1940 Germany overwhelmed Denmark and began its conquest of  Norway. In May German forces swept through The Netherlands and Bel�  gium on their blitzkrieg invasion of France, forcing it to capitulate in June  and establish the Vichy France regime. Germany then launched massive  bombing raids on Britain in preparation for a cross-Channel invasion, but,  after losing the Battle of Britain, Hitler postponed the invasion indefinitely.  By early 1941 Hungary, Romania, and Bulgaria had joined the Axis, and  German troops quickly overran Yugoslavia and Greece in April. In June  Hitler abandoned his pact with the Soviet Union and launched a massive  surprise invasion of Russia, reaching the outskirts of Moscow before  Soviet counterattacks and winter weather halted the advance. In East Asia  Japan expanded its war with China and seized European colonial hold�  ings. In December 1941 Japan attacked U.S. bases at Pearl Harbor and  in the Philippines. The U.S. declared war on Japan, and the war became  truly global when the other Axis Powers declared war on the U.S. Japan  quickly invaded and occupied most of Southeast Asia, Burma, the Neth-</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>World Wide Web &#x25BA; Worth I 2079</p><p>erlands East Indies, and many Pacific islands. After the crucial U.S. naval  victory at the Battle of Midway (1942), U.S. forces began to advance up  the chains of islands toward Japan. In the North Africa Campaigns the  British and Americans defeated Italian and German forces by 1943. The  Allies then invaded Sicily and Italy, forcing the overthrow of the fascist  government in July 1943, though fighting against the Germans continued  in Italy until 1945. In the Soviet Union the Battle of Stalingrad (1943)  marked the end of the German advance, and Soviet reinforcements in  great numbers gradually pushed the German armies back. The massive  Allied invasion of western Europe began with the Normandy Campaign in  western France (1944), and the Allies� steady advance ended in the occu�  pation of Germany in 1945. After Soviet troops pushed German forces  out of the Soviet Union, they advanced into Poland, Czechoslovakia,  Hungary, and Romania and had occupied the eastern third of Germany by  the time the surrender of Germany was signed on May 8, 1945. In the  Pacific an Allied invasion of the Philippines (1944) was followed by the  successful Battle of Leyte Gulf and the costly Battles of Iwo Jima and Oki�  nawa (1945). Atomic bombs were dropped on Hiroshima and Nagasaki in  August 1945, and Japan�s formal surrender on September 2 ended the war.  Estimates of total military and civilian casualties varied from 35 million  to 60 million killed, including about 6 million Jews who died in the Holo�  caust. Millions more civilians were wounded and made homeless through�  out Europe and East Asia.

The Web gives users access  to a vast array of documents that are connected to each other by means  of hypertext or hyperlinks. A hypertext document with its corresponding  text and hyperlinks is written in HTML and is assigned an on-line address,  or URL. The Web operates within the Internet�s basic client-server archi�  tecture. Individual HTML files with unique electronic addresses are called  Web pages, and a collection of Web pages and related files (such as  graphics files, scripted programs, and other resources) sharing a set of  similar addresses (see domain name) is called a Web site. The main or intro�  ductory page of a Web site is usually called the site�s home page. Users  may access any page by typing in the appropriate address, search for pages  related to a topic of interest by using a search engine, or move quickly  between pages by clicking on hyperlinks incorporated into them. Though  introduced in 1991, the Web did not become truly popular until the intro�  duction of Mosaic, a browser with a graphical interface, in 1993.

The  major phyla are Platyhelminthes (flatworms), Annelida (annelids, or seg�  mented worms), Nemertea (ribbon worms), Acanthocephala (spiny-  headed worms), and Aschelminthes (nematodes and others). There are  several minor phyla. Length ranges from microscopic (e.g., some aschel-  minths) to more than 100 ft (30 m) (some ribbon worms). Worms are  found worldwide on land and in water. They may be parasitic or free-  living and are important as soil conditioners, parasites, and a link in the  food chain in all ecosystems.

Hayes. Leaders of the Democratic and Republican parties met at  Wormley�s Hotel in Washington, D.C., to reach a compromise that would  forestall the Democrats� protest of the Electoral Commission�s decision to  award the disputed electoral votes from three Southern states to Hayes,  enabling him to defeat Tilden 185 to 184. In return for the Democrats�  acquiescence in the decision, Republicans promised to withdraw troops  from the South, end Reconstruction and Northern interference in South�  ern politics, and vote for railroad construction and other internal improve�  ments in the South. The compromise satisfied the Southern Democrats,  and Hayes was declared the winner on March 2, 1877.</p><p>Worms Worms,\ English VwormzV Concordat of (1122) Compro�  mise between Pope Calixtus II and Emperor Henry V (r. 1106-25) to settle  the Investiture Controversy, reached at Worms, Germany. It marked the  end of the first phase of conflict between Rome and what was becoming  the Holy Roman Empire and made a clear distinction between the spiritual  side of a prelate�s office and his position as a landed magnate and vassal  of the crown. Bishops and abbots were to be chosen by the clergy, but  the emperor was to decide contested elections. Those selected were to be  invested first with the powers and privileges of their office as vassal  (granted by the emperor) and then with their ecclesiastical powers and  lands (granted by church authority).</p><p>Worms, Diet of Meeting of the Diet (assembly) of the Holy Roman  Empire at Worms, Ger., in 1521, where Martin Luther defended the prin�  ciples of the Reformation. Luther had already been excommunicated by  Pope Leo X, but Emperor Charles V granted him safe conduct to a hearing  at the Diet. On April 17, 1521, Luther refused to recant his views. Dis�  order broke out, the emperor adjourned the proceedings, and Luther was  obliged to go into hiding. In May the Diet issued the Edict of Worms,  declaring Luther an outlaw and a heretic and banning his writings.</p><p>worsted Vwus-tod, �wor-stodV Wool yarn made of long-staple fibres that  have been combed to remove unwanted short fibres and make them lie  parallel.

It may be closed (blunt trauma) or open (penetrating  trauma). Blood vessels, nerves, muscles, bones, joints, and internal organs  may be damaged. A closed wound can be caused by impact, twisting,  bending, or deceleration (as in a car crash). It can range from a minor  bruise or sprain to a skull fracture with brain damage or a spinal-cord  injury with paralysis. In an open wound, foreign matter such as bacteria,  dirt, and clothing fragments entering through broken skin or mucous  membrane may result in infection. Other factors affecting severity include  depth, surface area, degree of tearing, and structures damaged. Minor  wounds need only first aid. For others, after examination and perhaps  diagnostic imaging and exploratory surgery, treatment may include fluid  replacement or drainage, sterilization and antibiotics, tetanus antitoxin,  and repair of damaged structures. A closed wound may need to be opened  or an open one sutured closed.

In 1890 the Sioux had been inspired by the Ghost Dance movement to  take up arms and reclaim their heritage, but federal military intervention  quelled the rebellion. On December 29 a young brave became involved  in a scuffle while surrendering, and a trooper was killed. Soldiers fired at  the Indians, killing more than 200 men, women, and children. Thirty sol�  diers also died. The so-called Battle of Wounded Knee is regarded as the  final episode in the conquest of the North American Indian. In 1973 some  200 members of the American Indian Movement took the reservation ham�  let by force, declared it an independent nation, and vowed to stay until  the government agreed to address Indian grievances; a siege by federal  marshals ended when the Indians surrendered in exchange for a promise  of negotiations.</p><p>Wovoka \wo-'vo-k9\ (b. 18587, Utah Territory, U.S.�d.

Created in 1935 under the New Deal, it aimed to stimulate the  economy during the Great Depression and preserve the skills and self-  respect of unemployed persons by providing them useful work. During  its existence, it employed 8.5 million people in the construction of  650,000 mi (1,046,000 km) of roads, 125,000 public buildings, 75,000  bridges, 8,000 parks, and 800 airports. The WPA also administered the  WPA Federal Art Project, the Theater Project, and the Writers� Project,  which provided jobs for unemployed artists, actors, and writers. In 1943,  with the virtual elimination of unemployment by the wartime economy,  the WPA was terminated.</p><p>WPA Federal Art Project Extensive visual-arts project, part of the  Works Progress Administration established by Franklin D. Roosevelt dur�  ing the Great Depression. It employed artists with a wide range of expe�</p><p>rience and styles and had great influence on subsequent U.S. movements.  At its peak in 1936, it provided work for more than 5,000 artists from  relief rolls. Over the eight years of its existence, its employees produced  2,566 murals, more than 100,000 easel paintings, about 17,700 sculptures,  and nearly 300,000 fine prints. The project also developed an audience by  establishing more than 100 community art centres and galleries in regions  where art was generally unknown. The total federal investment was about  $35 million. It was the first major attempt at U.S. government patronage  of the visual arts.</p><p>Wrangel, Pyotr (Nikolayevich), Baron (b.

A member of an old German baronial family, he served in the  Russian imperial guards and commanded a Cossack division in World War  I. After the Russian Revolution of 1917, he joined the anti-Bolshevik  �White� forces of Anton Denikin. After capturing Tsaritsyn (now Volgo�  grad) in 1919, he became commander of the Whites in April 1920 and  tried to rally support from the peasants and Cossacks. He launched an  offensive in Ukraine in June, but by November the Red Army had defeated  the Whites and forced them to retreat to the Crimea. After evacuating his  troops to Constantinople, he lived in exile in western Europe.</p><p>Wrangel Island Island, northeastern Russia. Located in the Arctic  Ocean, it is crossed by the 180th meridian. It has an area of some 2,800  sq mi (7,300 sq km). Although it reaches an altitude of 3,596 ft (1,096  m) at Sovetskaya Mountain, there are no glaciers. The Russian explorer  Ferdinand P. Wrangel, for whom the island was later named, determined  its location from accounts of Siberian natives but did not land there dur�  ing his mapping of the Siberian coast in the early 1820s. Russian fur trad�  ers subsequently visited the island, and it was sighted by U.S. vessels in  1867 and 1881. Survivors of a sunken Canadian ship reached Wrangel in  1914, and the leader of the expedition created an international incident in  the early 1920s when he claimed Wrangel for Canada without authoriza�  tion. The Soviet Union then annexed the island, and permanent occupa�  tion began in 1926.

She was a co-leader of the Workingmen's Party. After marry�  ing and living in France (1831-35), she returned to the U.S. and became  a supporter of Andrew Jackson and the Democratic Party.</p><p>Wright, Frank Lloyd (b. June 8, 1867, Richland Center, Wis.,  U.S.�d. April 9, 1959, Phoenix, Ariz.) U.S. architect. After studying  engineering briefly at the University of Wisconsin, he worked for the firm  of Dankmar Adler (1844-1900) and Louis Sullivan in Chicago before open�  ing his own practice there in 1893. Wright became the chief practitioner  of the Prairie school, building about 50 Prairie houses from 1900 to 1910.</p><p>Early nonresidential buildings include the forward-looking Larkin Build�  ing in Buffalo, N.Y. (1904; destroyed 1950), and Unity Temple in Oak  Park, Ill. (1906). In 1911 he began work on his own house, Taliesin, near  Spring Green, Wis. The lavish Imperial Hotel in Tokyo (1915-22, dis�  mantled 1967) was significant for its revolutionary floating cantilever  construction, which made it one of the only large buildings to withstand  the earthquake of 1923. In the 1930s he designed his low-cost Usonian  houses, but his most admired house, Fallingwater, in Bear Run, Pa.  (1936), is an extravagant country retreat cantilevered over a waterfall. His  Johnson Wax Building (1936-39), an example of humane workplace  design, touched off an avalanche of major commissions. Of particular note  is the Guggenheim Museum (1956-59), which has no separate floor levels  but instead uses a spiral ramp, realizing Wright�s ideal of a continuous  space. Throughout his career he retained the use of ornamental detail,  earthy colours, and rich textural effects. His sensitive use of materials  helped to control and perfect his dynamic expression of space, which  opened a new era in American architecture. Often considered the great�  est U.S. architect of all time, his greatest legacy is �organic architecture,�  or the idea that buildings harmonize both with their inhabitants and with  their environment.</p><p>Wright, Mickey orig. Mary Kathryn Wright (b. Feb. 14, 1935,  San Diego, Calif., U.S.) U.S. golfer. Noted for her classic swing, her long  drives, and her superior iron play, she won a record number of LPGA  tournaments (82), including an unmatched 13 in one season (1963), and  remains the only four-time winner of the LPGA Championship (1958,  1960, 1961, 1963). Twice named Woman Athlete of the Year by the Asso�  ciated Press (1963, 1964), she has been called the greatest woman golfer  of all time.</p><p>Wright, Richard (b. Sept. 4, 1908, near Natchez, Miss., U.S.�d. Nov.  28, 1960, Paris, France) U.S. novelist and short-story writer. Wright,  whose grandparents had been slaves, grew up in poverty. After migrating  north he joined the Federal Writers� Project in Chicago, then moved to  New York City in 1937. He was a member of the Communist Party in the  years 1932-44. He first came to wide attention with a volume of novel�  las, Uncle Tom�s Children (1938). His novel Native Son (1940), though  considered shocking and violent, became a best-seller. The fictionalized  autobiography Black Boy (1945) vividly describes his often harsh child�  hood and youth. After World War II he settled in Paris. He is remembered  as one of the first African American writers to protest white treatment of  blacks.</p><p>Wright, Sewall (b. Dec. 21, 1889, Melrose, Mass., U.S.�d. March 3,  1988, Madison, Wis.) U.S. geneticist. He earned his doctorate at Harvard  University. His earliest studies included investigation of the effects of  inbreeding and crossbreeding on guinea pigs, animals he later used in  studying the effects of gene action on coat and eye colour. With J.B.S.  Haldane and R.A. Fisher, he developed a mathematical basis for modem  evolutionary theory using statistical techniques. He originated a theory  that could guide the use of inbreeding and crossbreeding in livestock  improvement. He is perhaps best known for his concept of genetic drift.</p><p>Wright, Wilbur; and Wright, Orville (respectively b. April 16,  1867, near Millville, Ind., U.S.�d. May 30, 1912, Dayton, Ohio; b. Aug.  19, 1871, Dayton, Ohio, U.S.�d. Jan. 30, 1948, Dayton) U.S. inventors  who achieved the first powered, sustained, and controlled airplane flight.  The brothers first worked in printing-machinery design and later in bicycle  manufacturing, which financed their early experiments in airplane design.  To test flight control, essential to successful powered flight, they built and  flew three biplane gliders (1900-02). Propeller and engine innovations  led to their first powered airplane, which Orville flew successfully for 12  seconds and Wilbur later flew for 59 seconds at Kill Devil Hills, N.C.  (near the village of Kitty Hawk), on Dec. 17, 1903. Their flyer of 1905  could turn, bank, circle, and remain airborne for over 35 minutes. They  demonstrated their planes in Europe and the U.S.; in 1908 Wilbur gave  over 100 exhibition flights in France, setting a duration record of 2 hours  and 20 minutes. They established an aircraft company and produced  planes for the U.S. Army. After Wilbur�s death from typhoid, Orville sold  his interest in the company, which later merged with the company of  Glenn H. Curtiss.</p><p>Wriothesley, Thomas See 1st Earl of Southampton</p><p>writ In common law, an order issued in the name of a sovereign or court  commanding a person to perform or refrain from performing a specified  act.

Its precursor was  pictography. Logography, in which symbols stand for individual words,  typically develops from pictography. Logography requires thousands of  symbols for all possible words and names. In phonographic systems, the  symbol associated with a word also stands for similar- or identical-  sounding words. Phonographic systems may evolve to the point where  symbols represent syllables, constituting a syllabary. An alphabet provides  symbols for all the consonants and vowels.</p><p>Writs of Assistance See Writs of Assistance</p><p>Wroctaw \'vr6t-,swaf\ German Breslau City (pop., 2000 est.:  633,857), southwestern Poland. Located on the Oder River, it originated  in the 10th century at the crossroads of the trade route linking the Black  Sea to western Europe. In 1138 it became the first capital of Silesia. The  Tartars destroyed Wroclaw in 1241. Rebuilt, it passed to Bohemia with the  rest of Silesia in 1335 and to the Habsburgs in 1526. In 1741 it fell to  Prussia under the rule of Frederick II (the Great), and it eventually became  part of Germany. During World War II Wroclaw was besieged (1945) by  Soviet troops. The city was assigned to Poland by the Potsdam Confer�  ence of 1945. Heavily damaged during the war, it was rebuilt and is now  a major commercial city.</p><p>wrought iron One of the two forms in which iron is obtained by smelt�  ing. Wrought iron is a soft, easily worked, fibrous metal. It usually contains  less than 0.1% carbon and 1-2% slag. It is superior for most purposes to  cast iron, which is hard and brittle because of its higher carbon content. In  antiquity, iron was smelted directly by heating ore in a forge with charcoal,  which served both as fuel and reducing agent. While still hot, the iron-and-  slag mixture was removed as a lump and worked (wrought) with a hammer  to expel most of the slag and weld the iron into a coherent mass. Wrought  iron began to take the place of bronze (being far more available) in Asia  Minor in the 2nd millennium bc; its use for tools and weapons was estab�  lished in China, India, and the Mediterranean by the 3rd century bc. Later,  in Europe, wrought iron was produced indirectly from cast iron (see pud�  dling process). With the invention of the Bessemer process and open-hearth  process, steel supplanted wrought iron for structural purposes, and its use in  the 20th century has been principally decorative.</p><p>wu Fundamental Daoist philosophical concept. Wu (�not-being�), you  (�being�), wuming (�the nameless�), and youming (�the named�) are inter�  dependent and grow out of one another. Wu and you are two aspects of  the DAO. Not-being does not mean nothingness but rather the absence of  perceptible qualities; in Laozi�s view, it is superior to being. It is the void  that harbours in itself all potentialities and without which even being lacks  its efficacy. According to the scholar He Yan (d. 249), wu is beyond name  and form and hence is absolute, complete, and capable of accomplishing  anything. See also Daoism.</p><p>Wu Cheng'en or Wu Ch'eng-en Vwu-'chsq-'onX (b. c. 1500, Shan-  yang, Huaian, China�d. c. 1582, Huaian) Chinese novelist and poet. He  received a traditional Confucian education and became known for his  clever poetry and prose composition in the classical style. Interested in  bizarre stories, he used oral and written folktales as the basis of the novel  Xiyouji (Journey to the West, also partially translated as Monkey), pub�  lished anonymously in 1592. It relates the comic mishaps and adventures of  the 7th-century monk Xuanzang, who traveled to India looking for sacred  texts, and his entourage of three animal spirits: a monkey, a pig, and a fish.  It satirizes Chinese society and government and contains religious and  philosophical elements drawn from Buddhism, Daoism, and Neo-  Confucianism. Only two volumes of his other writings have survived.</p><p>Wu-lu-mu-ch'i See Urumqi</p><p>Wu Sangui or Wu San-kuei Vwii-'san-�gwaX (b. 1612, Liaodong,  China�d. Oct. 2, 1678, Hengzhou, Hunan province) Chinese general who</p><p>invited the Manchu into China and helped them establish the Qing dynasty.  Though he had for many years battled the Manchu on China�s northeast�  ern frontier, he turned to them for aid when the Ming-dynasty capital at  Beijing fell to rebel leader L Zicheng. The Manchu forces defeated Li and  then set up their own dynasty, in which Wu served many years. Only when  he was put in charge of eliminating the remnants of Ming resistance in  southwestern China did he break away, creating his own state in the area  of Yunnan and Guizhou. Two other commanders had set up similar states  in neighbouring southern provinces; in 1673 Wu led the three in rebel�  lion. After Wu�s death, his grandson continued the rebellion until 1681,  when it was finally crushed.

It is the oldest of the Wuhan cities, probably dating from the  Han dynasty. It was the capital of the kingdom of Wu in the 3rd century  ad, as well as capital of an administrative district under the Yuan dynasty  (1279-1368) and later capital of Hubei province (until 1950). In 1911 it  was the starting point of the revolution against the imperial regime. The  Japanese occupied the city in 1938�45; the Chinese communists took it  in 1949. It became part of Wuhan in 1950.</p><p>Wudi or Wu-ti Vwu-'de\ orig. Liu Che (b. 156 bc �d. March 29, 87  bc) Emperor of the Chinese Han dynasty who vastly increased its author�  ity and its influence abroad and made Confucianism China�s state religion.  Under Wudi, China�s armies drove back the nomadic Xiongnu tribes that  plagued the northern border, incorporated southern China and northern  and central Vietnam into the empire, and reconquered Korea. Their far�  thest expedition was to Fergana (in modern Uzbekistan). Wudi�s military  campaigns strained the state�s reserves; seeking new income, he decreed  new taxes and established state monopolies on salt, iron, and wine.</p><p>Wuhan \'wu-'han\ or Wu-han City (pop., 1999 est.: 3,911,824), capi�  tal of Hubei province, east-central China. It is located at the confluence of  the Han and Yangtze (Chang) rivers and is a conurbation of three cities  that merged in 1950: Hankou, on the north bank of the Yangtze; Hanyang,  across the Han; and Wuchang, on the south bank of the Yangtze. The chief  industrial and commercial centre of central China, it is a hub of maritime,  river, rail, and road transportation. It serves as the collection and distri�  bution point for the products of the middle Yangtze valley and for west�  ern and southwestern China. It has numerous industries, including iron-  and steel-producing complexes. It is the seat of Wuhan University and the  Central China Technical University.</p><p>Wuhou or Wu-hou Vwu-'ho\ or Wu Zetian \'wu-dz3-'tyan\ (b. 624,  Wenshui, Shanxi province, China�d. Dec. 16, 705, Louyang) Empress  of China during the Tang dynasty. She began her career as the concubine  of the emperor Taizong but became the consort of his son. She eliminated  her female rivals and became empress in 655. By 660, through dismissal,  exile, and execution, she had eliminated those who opposed her. Because  the emperor was sickly, Wuhou was able to rule in his name; after his  death she ruled in the name of her sons, at last declaring herself ruler in  her own name in 690. To support her reign, she claimed to be an incar�  nation of the bodhisattva Maitreya. Though long vilified for her cruelty  and her methods of maintaining power, she supported the development of  a scholarly bureaucracy to replace rule by aristocratic families, stabilized  the dynasty, and unified the empire.</p><p>Wundt Vvunt\, Wilhelm (b.Aug. 16, 1832, Neckarau, near Mannheim,  Baden�d. Aug. 31, 1920, Grossbothen, Ger.) German physiologist and  psychologist, the founder of experimental psychology. After earning a medi�  cal degree, he studied briefly with Johannes Peter MOller and later assisted  Hermann von Helmholtz. At the University of Heidelberg in 1862, follow�  ing publication of his Contributions to the Theory of Sense Perception  (1858-62), he gave the first course in scientific psychology. In Principles  of Physiological Psychology (1873-74) he claimed that psychology must  be based directly on experience and that its proper method was that of  controlled introspection. At the University of Leipzig (1875-1917), he  established the first psychological laboratory (1879) and founded the first  journal of psychology (1881). His later works include Outline of Psychol�  ogy (1896) and Ethnic Psychology (10 vol., 1900-20).</p><p>Wupatki \wu-'pat-ke\ National Monument National monument,  north-central Arizona, U.S. Situated along the Little Colorado River, the</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Wuppertal &#x25BA; Wyeth I 2083</p><p>monument was established in 1924 and comprises more than 800 red  sandstone pueblos built during the 11th�13th centuries.

Its name  was changed to Wuppertal in 1930. The region was noted for its textile  production as early as the 16th century, and the modem city remains a  textile-manufacturing centre. Other industrial products include chemicals,  rubber, and machinery. Wuppertal has numerous parks and public gardens  and a well-known zoo.</p><p>Wurlitzer, (Franz) Rudolph (b. Jan. 30, 1831, Schoneck,  Saxony�d. Jan. 14, 1914, Cincinnati, Ohio, U.S.) German-born U.S.  musical instrument manufacturer. He immigrated to the U.S. in 1853 and  with his brother founded the Wurlitzer Co. in 1872. His son Howard  (1871-1928) introduced the innovation of automatic instruments, which  led to the firm�s production of self-playing organs, electronically con�  trolled organs, and finally the organs it is best known for, in which vibrat�  ing reeds rather than pipes produce the sound.</p><p>Wurttemberg Vvuer-tom-.berkA English Vwur-tom-.borgV Former  state, Germany. Its territory approximated the central and eastern areas of  the present-day German state of Baden-Wurttemberg. The capital was  Stuttgart. Originally inhabited by Celts, Wurttemberg was occupied suc�  cessively by Suevi, Romans, Alemanni, and Franks. In the Middle Ages  it was part of Swabia. Wurttemberg became an electorate in 1803 and a  kingdom in 1806. A constitutional monarchy (1819-1918), it became an  independent republic in 1918 but joined the Weimar Republic in 1919. Wurt�  temberg came under the control of the Third Reich in 1934. During World  War II the Allies overran it (1945). It was made part of Baden-  Wtirttemberg in 1952.</p><p>Wuwang or Wu-wang Vwu-'waq\ (fl. 11th century bc, China)  Founder and first ruler of the Zhou dynasty. After establishing the Zhou  dynasty, Wuwang, assisted by his brother, Zhougong, consolidated his  rule by establishing a feudalistic form of government in which territory  was bestowed on relatives and vassals willing to acknowledge Zhou suzer�  ainty. He was regarded by later Confucians as a wise king.</p><p>Wyandot or Huron North American Indian people living in Lorette,  north of Quebec city, Que., and in southwestern Ontario, Can.; and in  Kansas and Oklahoma, U.S. Their language is of the Iroquoian family. At  first contact, the people who mostly call themselves Wyandot lived in  Ouendake (Huronia), between Georgian Bay and Lake Simcoe. Their vil�  lages, sometimes palisaded, consisted of large, bark-covered dwellings  that housed several families related through maternal descent. Crops  included com, beans, squash, sunflowers, and tobacco. Hunting and fish�  ing were of lesser importance. Villages were divided into clans, the chiefs  of which formed councils. Women were influential in clan affairs, and  clan matrons had the responsibility of selecting political leaders. The  Wyandot were bitter enemies of tribes of the Iroquois Confederacy, with  whom they competed in the fur trade. Iroquois invasions in 1648-50 dev�  astated the tribe, forcing a remnant westward. Today the Wyandot, or  Wyandotte, as they are known in the U.S. number about 6,800 in the U.S.  and Canada.</p><p>Wyat, Thomas or Thomas Wyatt later Sir Thomas (b. 1503,  Allington, near Maidstone, Kent, Eng.�d. Oct. 6, 1542, Sherborne, Dor�  set) English poet. A member of the court circle of Henry VIII, he was  apparently admired for his skill in music, languages, and arms. He served  a number of diplomatic missions, but his reputation rests on his poetic  achievements, especially his introduction into English literature of the  Italian sonnet and terza rima verse form and the French rondeau. His  works, unusual for their time in carrying a strong sense of individuality,  include Certayne Psalmes ...drawen into Englyshe meter (1549), three  satires, and songs.</p><p>Wyatt, John (b. April 1700, Lichfield, Staffordshire, Eng.�d. Nov. 29,  1766, Birmingham, Warwickshire) British mechanic who contributed to  the development of power spinning. He began his career as a carpenter,  but by 1730, with financial support from Lewis Paul, he was working on  machines for boring metal and making files. The spinning machine (see  drawing frame), first patented in 1738, was almost certainly Paul�s idea,  with Wyatt providing technical skill; its principle was to draw the fibres</p><p>through sets of rollers turning at different speeds. It was superseded by  Richard Arkwright�s water frame in the 1770s.</p><p>Wycherley Vwi-chor-leV William (b. 1640, Clive, near Shrewsbury,  Shropshire, Eng.�d. Jan. 1, 1716, London) English dramatist. After  attending Oxford and studying law, Wycherley became a man-about-town  with an interest in theatre. Within the framework of the comedy of man�  ners, he attempted to reconcile a deep-seated puritanism with his ardent  physical nature. Love in a Wood (1671) first won him favour in the Res�  toration court, and The Plain-Dealer (1676) satirized rapacious greed. In  The Country-Wife (1675), perhaps his best work, a satirical comment on  excessive jealousy and complacency is blended with a richly comic and  bawdy presentation. He eventually lost favour at court and spent seven  years in debtor�s prison until he was rescued by James II.</p><p>Wycliffe Vwi- I klif\ / John (c. 1330-1384) British theologian, philoso�  pher, and church reformer. He earned a doctor-of-divinity degree from  Oxford in 1372. Named by Edward III to a deputation to discuss English  differences with the papacy, he represented the government in its attempts  to limit the church�s power in England. His preaching against church  policies, in which he argued that the church itself was sinful and should  relinquish its possessions and return to evangelical poverty, attracted wide  attention, and in 1377 the pope called for his arrest. In 1379 he began  systematically attacking the foundations of Roman Catholicism, notably  by repudiating the doctrine of transubstantiation and by denying that the  church hierarchy represented a line of authoritative succession from Jesus.  In 1380 he became involved in a translation of the Bible into English,  seeking to bypass the church in making the law of God accessible to all  literate people. His followers were known as Lollards. He was blamed by  his ecclesiastical superiors for inciting the Peasants' Revolt (1381); many  of his works were subsequently banned. His writings later inspired the  leaders of the Reformation, most notably Martin Luther.</p><p>Wye, River River, eastern Wales and western England. It flows from  the moorlands of central Wales southeast across the English border and  continues south into the estuary of the River Severn. It is about 130 mi  (210 km) long.

July 12, 1917, Chadds Ford,  Pa., U.S.) U.S. painter. He was trained by his father, N.C. Wyeth. His  subject matter comes almost entirely from the area around Chadds Ford  and around his summer home in Cushing, Maine. Though his technique  is precise and detailed, he uses it to achieve an unreal, visionary quality.  His palette is restricted largely to earth colours. His famous Christina�s  World (1948), depicting a polio victim seemingly trying to climb a hill,  exemplifies his mastery of unusual angles and his use of light to pinpoint  time. Between 1971 and 1985 Wyeth secretly painted Helga Testorf, his  neighbour in Chadds Ford, creating hundreds of images of her, including  nudes. He was the first painter ever awarded the Presidential Medal of  Freedom (1963) and the first artist to receive the Congressional Gold  Medal (1990). His son Jamie (b. 1946) has also had a successful painting  career.</p><p>Christina's World, tempera on gesso panel by Andrew Wyeth, 1948; in the  Museum of Modern Art, New York City.</p><p>COURTESY OF THE MUSEUM OF MODERN ART, NEW YORK CITY</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2084 I Wyeth &#x25BA; Wythe</p><p>Wyeth, N(ewell) C(onvers) (b.

After studies  in France and Switzerland, he immigrated to New York in 1920. Work�  ing for Universal Pictures, he became a director of low-budget westerns,  but he established a serious reputation with Counsellor-at-Law (1933) and  went on to direct successes such as Dodsworth (1936), Wuthering Heights  (1939), and The Little Foxes (1941). His films are noted for their clear  narrative style and sensitive handling of human relationships. He won  Academy Awards for Mrs. Miniver (1942) and The Best Years of Our Lives  (1946), and he later directed popular movies such as Roman Holiday  (1953), Ben-Hur (1959, Academy Award), and Funny Girl (1968).</p><p>Wynelte \wl-'net\, Tammy orig.

She  worked as a beautician before appearing on Porter Wagoner�s country  music television show. In 1967-68 she had hits with �Your Good Girl�s  Gonna Go Bad,� �D-I-V-O-R-C-E,� and her anthem, �Stand by Your  Man.� She was married to George Jones (1969-75), with whom she  recorded many duet hits; despite their divorce, they continued to collabo�  rate on recordings, including her last album, One (1996). She recorded 20  number-one country hits and 50 albums.</p><p>Wyoming State (pop., 2000: 493,782), western U.S. It covers an area  of 97,813 sq mi (253,334 sq km); its capital is Cheyenne. Wyoming is bor�  dered on the north and northwest by Montana, on the east by South Dakota  and Nebraska, on the south by Colorado, on the southwest by Utah, and  on the west by Idaho. It contains part of the Great Plains and the Black  Hills. Its ranges of the Rocky Mountains include the Bighorn, Tetons, and  Wind River. Wyoming�s highest point is Gannett Peak, at 13,804 ft (4,207  m). The Continental Divide crosses the state northwest to southeast. About  three-fourths of its rivers drain eastward into the Missouri-Mississippi  system. Its largest lake is Yellowstone Lake. Wyoming was already inhab�  ited by Plains Indians, including the Shoshone, when it was first visited  by European explorers during the 18th century. The Oregon and Over�  land trails crossed it. Most of the area was acquired by the U.S. from  France in the Louisiana Purchase. The Lewis and Clark Expedition did not  cross the area, but a member of the group, John Colter, strayed from the</p><p>expedition and spent time in Wyoming. It was included in several U.S.  territories before the organization of the Wyoming Territory in 1868. It  adopted woman suffrage in 1869 and in 1889 was the first state to include  that right in its constitution. In the years preceding statehood, it devel�  oped a thriving cattle industry. It was admitted to the Union in 1890 as  the 44th state. In 1924 it elected the first U.S. woman governor, Nellie  Tayloe Ross. Though livestock is still important to its modern economy,  mining is increasingly influential and tourism is growing.</p><p>Wyoming Massacre (July 3, 1778) Killing of American settlers by  the British in the Wyoming Valley of Pennsylvania. In the American Revo�  lution, British Col. John Butler led a force of 1,000 loyalists and Iroquois  allies against 5,000 settlers in the valley, many of whom were gathered  at Forty Fort.

Polish  cardinal and primate of Poland. Ordained in 1924, he was assigned to the  basilica at Wloclawek. He founded and directed the Christian Workers  University (1935-39), then joined the Polish resistance in World War II.  He was appointed successively bishop of Lublin (1946), primate of Poland  (1948), and cardinal (1952). For refusing to consent to communist  demands, he was placed under house arrest (1953-56). After his release,  he reached a compromise on church and state matters with WtADYStAW  Gomulka that avoided a potential Soviet invasion of Poland, and he there�  after maintained the unity of the church in an uneasy coexistence with the  communist government. He later lent cautious support to such Polish  movements as the Workers� Defense Committee, Solidarity, and Rural  Solidarity, which sought greater freedom from the late 1970s onward. A  doctrinal conservative, his last major act was to negotiate with the Polish  authorities over the visit of Pope John Paul II to Poland in 1979.</p><p>Wythe Vwith\, George (b. 1726, Elizabeth City county, Va.�d.

He practiced law in Williamsburg, Va.,  where he taught Thomas Jefferson. At the College of William and Mary  (1779-89) he became the first professor of law in the U.S.; among his  pupils was John Marshall. A delegate to the Continental Congress, he  signed the Declaration of Independence. In 1776 he was appointed, with  Jefferson and two others, to revise the laws of Virginia. As a chancery  judge (1778-1806), he asserted, in Commonwealth v. Caton (1782), the  power of courts to refuse to enforce unconstitutional laws. He was a  member of the Constitutional Convention (1787) and of the Virginia con�  vention (1788) that ratified the Constitution of the United States.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>X-ray &#x25BA; Xenophon I 2085</p><p>X-ray Electromagnetic radiation of extremely short wavelength (100  nanometres to 0.001 nanometre) produced by the deceleration of charged  particles or the transitions of electrons in atoms. X-rays travel at the speed  of light and exhibit phenomena associated with waves, but experiments  indicate that they can also behave like particles (see wave-particle duality).  On the electromagnetic spectrum, they lie between gamma rays and ultra�  violet radiation. They were discovered in 1895 by Wilhelm Conrad Ront-  gen, who named them X-rays for their unknown nature. They are used in  medicine to diagnose bone fractures, dental cavities, and cancer; to locate  foreign objects in the body; and to stop the spread of malignant tumours.  In industry, they are used to analyze and detect flaws in structures. See  illustration below.</p><p>X-ray astronomy Study of astronomical  objects and phenomena that emit radiation at X-ray  wavelengths. Because Earth�s atmosphere absorbs most  X-rays, X-ray telescopes and detectors are taken to high  altitudes or into space by balloons and spacecraft. In 1949  detectors aboard sounding rockets showed that the Sun gives  off X-rays, but it is a weak source; it took 30 more years to  clearly detect X-rays from other ordinary stars. Beginning with  the Uhuru X-ray satellite (launched 1970), a succession of space  observatories carried increasingly sophisticated instruments into  Earth orbit. Astronomers discovered that most types of stars emit  X-rays but usually as a tiny fraction of their energy output.</p><p>Supernova remnants are more powerful X-ray sources; the  strongest sources known in the Milky Way Galaxy are certain  binary stars in which one star is probably a black hole. In  addition to myriad point sources, astronomers have  found a diffuse background of X-ray radiation ema�  nating from all directions; unlike cosmic background  radiation, it appears to have many distant individual sources. The Chandra  X-Ray Observatory and XMM-Newton X-ray satellite (both launched  1999) have made numerous discoveries relating to the nature and quantity  of black holes in the universe, the evolution of stars and galaxies, and the  composition and activity of supernova remnants.</p><p>X-ray diffraction Phenomenon in which the atoms of a crystal, by  virtue of their uniform spacing, cause an interference pattern of the waves  in an incident beam of X-rays.

Interested in  expressing mathematical structures in music, he  used the term �stochastic music� to refer to situa�  tions in which the number of elements precludes  prediction of what each element will do but the  overall behaviour of the group is determinate (see stochastic process). He  often based his compositions on standard concepts of mathematics and  physics, such as the Fibonacci sequence ( Metastasis , 1954), the Boltzmann  constant (.

To avenge Darius�s defeat by the Greeks at the Battle of Marathon, he  spent three years raising a massive army and navy. When a storm  destroyed the bridges he had built to cross the Hellespont, he had them  rebuilt and for seven days oversaw the crossing of his army, numbering  360,000 troops by modern estimates, supported by more than 700 ships.  The Persians broke through at the Battle of Thermopylae and pillaged Ath�  ens, but then lost their navy at the Battle of Salamis (480).

April 762, Chang�an) Sixth emperor (r. 712-756) of  the Tang dynasty of China, which during his reign achieved its greatest  prosperity and cultural brilliance. Xuanzong reformed the bureaucracy,  increased tax revenues through reregistering the population, improved the  transportation system, and established a permanent military force along  China�s northern frontiers. Toward the end of his reign, he withdrew  increasingly from government and came under the influence of his con�  sorts, including the notorious beauty Yang Guifei. The An Lushan Rebel�  lion of 755-756 forced him to flee the capital, Chang 7 an (modern Xi�an),  and he abdicated in favour of the heir apparent.</p><p>Xunzi or Hsun-tzu Vshuen-'dzoV (b. c. 300, Zhao kingdom, China�d.  c. 230 bce, Lanling, Chu kingdom) Chinese scholar and philosopher. He  belonged to the academy of philosophy in the state of Qi before becom�  ing magistrate of a district in Chu in 255. His major work, the Xunzi,  taught that humanity is evil by nature and can become good only through  rigorous training. This view provoked much controversy because it  opposed the teachings of Mencius, who believed in innate human good�  ness. Xunzi�s teachings were later eclipsed when the Mencius became a  Confucian classic. Xunzi is regarded as one of the three great philoso�  phers of the classical period of Confucianism in China.</p><p>XX, Les See Les Vingt</p><p>xylem VzI-lomV Part of a plant�s vascular system that conveys water  and dissolved minerals from the  roots to the rest of the plant and fur�  nishes mechanical support. Xylem  constitutes the major part of a mature  woody stem or root and the wood of  a tree, and consists of specialized  water-conducting tissues made up  mostly of several types of narrow,  elongate, hollow cells. Xylem for�  mation begins when the actively  dividing cells of growing root and  shoot tips give rise to primary xylem.</p><p>Eventually the primary xylem is cov�  ered by secondary xylem produced  by the cambium. The primary xylem cells die, forming a hard skeleton that  supports the plant but loses its conducting function. Thus, only the outer  part of the wood (secondary xylem) serves in water conduction.</p><p>xylophone Percussion instrument consisting of a set of tuned wooden  bars that are struck with mallets.</p><p>Primitive xylophones may consist of  logs of graded length laid across two  supporting logs; a pit may be dug  underneath to serve as a resonator.</p><p>The xylophone has long been one of  the principal instruments of African  music; it is also important in the  Indonesian gamelan. The marimba is a  Latin American xylophone. In the  modern orchestral xylophone, the  bars are laid out on a stand in key�  board arrangement, with vertical  resonating tubes suspended under  each bar.

John Adams sent special  envoys Elbridge Gerry and John Marshall to France to help Charles C.  Pinckney negotiate an agreement to protect U.S. shipping from French pri�  vateers. Before the three could meet with Charles-Maurice de Talleyrand,  they were approached by three of his agents�called X, Y, and Z in dip�  lomatic correspondence to Adams�who suggested a bribe of $250,000  to Talleyrand and a loan of $10 million to France as preconditions for  negotiations. Adams rejected the French demands and reported the mis�  sion had failed. When he was forced to reveal the correspondence, pub�  lic outrage was followed by calls for war with France. The Alien and  Sedition Acts were passed to restrict potential French sympathizers. The  Convention of 1800 ended a period of undeclared naval warfare between  the U.S. and France.</p><p>Cross section of oak xylem</p><p>J.M.

Until the 1990s, most computer programs used only the last two  digits to designate the year, the first two digits being fixed at 19. As the  year 2000 approached, many programs had to be partly rewritten or  replaced to prevent interpretation of �00� as 1900 rather than 2000. It was  feared that such a misreading would lead to software and hardware fail�  ures in computers used in such important areas as banking, utilities sys�  tems, government records, and so on, with the potential for widespread  chaos on and following Jan. 1, 2000. Up to $200 billion may have been  spent (half in the U.S.) to upgrade computers and application programs  to be Y2K-compliant. Despite international alarm, few major failures  occurred, partly because these measures were effec�  tive and partly because the likely incidence of fail�  ure was exaggerated.</p><p>Ya-lung River See Yalong River</p><p>yacht \'yat\ Sail- or motor-driven vessel used for racing  or recreation. The term is popularly applied to large recre�  ational engine-powered boats; the sailboats known as yachts  and used for racing are usually light and comparatively small.</p><p>Until the mid-19th century, yachts were designed along the lines  of naval craft such as schooners and cutters. Yacht design was  greatly affected by the 1851 success of the America in the race that  established the America's Cup.

Soviet politician. A leader of the Cheka secret police  (1920-24) and its successor, the OGPU (1924-34), and a close associate  of Joseph Stalin, he organized the Soviet�s forced-labour camps from 1930  and became a member of the Communist Party�s Central Committee in  1934. As head of the Commissariat of Internal Affairs, or NKVD, he pre�  pared the first of the purge trials (1936). In 1937 he was replaced as police  chief by Nikolay Yezhov and himself became a victim of the widespread  purges. Accused of being a member of a �Trotskyite� conspiracy intent  on destroying the Soviet Union through sabotage, he was convicted, sen�  tenced to death, and executed.</p><p>yahrzeit or jahrzeit Vyar-.tsitX In Judaism, the anniversary of the death  of a parent or close relative, commonly observed by burning a candle for  an entire day. On that day, the Kaddish is recited in the synagogue, and  the Torah is read. Some mark the anniversary by studying portions of the  Mishna, choosing those sections from the sixth division that begin with  letters from the name of the deceased. Yahrzeit developed from an early  Jewish custom of fasting on the anniversaries of deaths of certain lead�  ers, and some Jews still fast on yahrzeit.</p><p>Yahweh See Tetragrammaton</p><p>yak Massive ox (Bos grunniens mutus ) of high Tibetan plateaus. Bulls  grow to 6 ft (1.8 m) at the shoulder  hump. The wild yak�s hair is black  and short, except for a long, shaggy  fringe on the flanks and tail. The  horns spread outward and upward;  the head is held low. Wild females  and young live in large herds; mature  bulls form smaller groups. Yaks  graze on grass and require much  water, eating snow in winter. Wild  yaks are now endangered. Domestic  yaks, which breed freely with  domestic cattle, are used as pack,  draft, milk, and beef animals. The  hide provides leather; the tail, fly  whisks; the fringe hair, ropes; the dried dung, fuel.</p><p>Yakima Vya-ko-.mo, 'ya-k9-m3\ River River, south-central Washing�  ton, U.S. Rising in the Cascade Range, it flows southeast for about 200  mi (320 km) to join the Columbia River near Kennewick. The Yakima and  its tributaries irrigate about 460,000 acres (190,000 hectares) in the river  valley.</p><p>yakuza Vya-ku-z3\ Japanese gangsters. Yakuza, who trace their roots  back to ronin (masterless samurai), often adopt samurai-like rituals and  identify themselves with elaborate body tattoos. They traditionally engage  in such organized-crime pursuits as extortion, blackmail, smuggling, pros�  titution, drugs, and gambling, and they control many restaurants, bars,  trucking companies, and taxi fleets in Japanese cities. In the 1980s they  also became involved in land speculation, fueling the �bubble economy�  that burst by the end of the decade. From a high of more than 180,000 in  the early 1960s, their membership has dropped to less than half that num�  ber. They are organized into some 2,000 gangs, most affiliated under the  umbrella of one of a dozen or fewer conglomerate gangs. Yakuza gangs  are rigidly hierarchical and follow strict codes of behaviour.</p><p>Yale University Private university in New  Haven, Conn., a traditional member of the Ivy  League. Founded in 1701, it is the third-oldest institu�  tion of higher learning in the U.S. Yale�s initial curricu�  lum emphasized classical studies and strict adherence to  orthodox Puritanism. Medical, divinity, and law schools  were added in 1810, 1822, and 1824. The geologist Benjamin  Silliman (1779-1864), who taught at Yale from 1802 to 1853,  did much to expand the experimental and applied sciences.  Beginning in the mid 19th century, schools of architecture, art,  drama, forestry, graduate studies, management, music, and nursing  were organized. Yale�s library, with more than 10 million volumes,  is one of the largest in the U.S. Its extensive art galleries were  established in 1832. The Peabody Museum of Natural History  houses important collections of paleontology, archaeology, and  ethnology. Yale is one of the most highly regarded schools in  the nation; its graduates have included several U.S. presi�  dents.</p><p>Yalong \'ya-luq\ River or Ya-lung River River, Sichuan province,  southern China. It rises in mountains at an elevation of nearly 16,500 ft  (5,000 m) in Qinghai province and flows into the Yangtze River (Chang  Jiang) on the Yunnan border. It is 822 mi (1,323 km) long.

She received  a Ph.D. in physics from the University of Illinois. She developed the  technique of radioimmunoassay (RIA) by combining techniques from  radioisotope tracing and immunology. RIA proved a very sensitive and  simple way to measure tiny concentrations of biological substances or  drugs in blood or other body fluids. She originally applied RIA to study  blood insulin levels in diabetes mellitus (1959), but the method soon  found hundreds of other applications. In 1976 she became the first woman  awarded the Albert Lasker Prize, and in 1977 she shared a Nobel Prize  with Andrew V. Schally and Roger C.L. Guillemin.</p><p>Yalta City (pop., 2001: 82,000), southern Crimea, Ukraine. It faces the  Black Sea on the southern shore of the Crimean Peninsula. Settlement on  the site dates from prehistoric times, but modern Yalta developed only in  the early 19th century, becoming a town in 1838. Its mild winters and  scenic location between sea and mountains have made it one of the most  popular vacation and health resorts of Ukraine. In 1945 during World War  II it was the site of the Allied leaders� Yalta Conference.</p><p>Yalta Conference (Feb. 4-11, 1945) Conference of Allied leaders at  Yalta to plan Germany�s defeat in World War II. Franklin Roosevelt, Win�  ston Churchill, and Joseph Stalin discussed the postwar occupation of Ger�  many, postwar assistance to the German people, German disarmament,  war-crimes trials, the fate of the defeated or liberated states of eastern  Europe, voting in the future United Nations Security Council, and German  reparations. Stalin agreed to enter the war against Japan after the German  surrender. Roosevelt died two months later, and Stalin broke his promise  to allow democratic elections in eastern Europe.

A number of species are cultivated for food in the tropics; in cer�  tain tropical cultures, notably of West Africa and New Guinea, the yam  is the primary agricultural commodity and the focal point of elaborate  ritual. The edible tuberous roots, which vary in taste from sweet to bitter  to tasteless, are eaten as cooked starchy vegetables. Often boiled and then  mashed, they may also be fried, roasted, or baked. True yams are botani-  cally distinct from the sweet potato, though in the U.S. the names are  commonly interchanged. Dioscorea mexicana contains a chemical that  can suppress ovulation in humans and is used as the basis for birth-control  pills. The so-called yam bean is the legume jicama.</p><p>Yama Vyo-moX In Indian mythology, the lord of death. The Vedas  describe him as the first man who died. The son of the sun god Surya, he  presides over the resting place of the dead. In the Vedas, he was a cheer�  ful king of the departed ancestors, but in later mythology he became  known as the just judge who punished the deceased for their sins.</p><p>Yamagata Aritomo X.ya-mo-'ga-to-.ar-e-'to-moX (b. Aug. 3, 1838,  Hagi, Japan�d. Feb 1, 1922, Tokyo) First prime minister under Japan�s  parliamentary regime (1889-91,1898-1900). As a samurai youth in ChoshO  province, Yamagata was among those who answered the foreign threat with  the slogan �Sonno joi� (�Revere the emperor, expel the barbarians�). In  1864 Western gunboats bombarded the Choshu coast, convincing him of  the need for modem armaments. After participating in the Meiji Restoration,  he went abroad to research military institutions, returning to become com�  mander of an imperial force of 10,000 troops. When he introduced con�  scription, bearing arms ceased to be the exclusive prerogative of a warrior  class. His forces defeated Saigo Takamori�s rebellion in 1877. In politics he  was more conservative than his contemporary ho Hirobumi, favouring a  strong executive. As prime minister, his policies were expansionist; Japan  sent the largest of all foreign forces to China to quell the Boxer Rebellion. He  increased the autonomy of the military and tried to suppress an incipient  social-labour movement. After retirement, he continued to wield power as  a genro (elder statesman).

April 18, 1943, Solomon Islands) Japanese naval  officer. He fought in the Russo-Japanese War and thereafter rose to  become commander in chief of Japan�s Combined Fleet in 1941. When  it was decided to go to war with the U.S., Yamamoto asserted that the  only chance for a Japanese victory lay in a surprise attack that would  cripple U.S. naval forces in the Pacific and conceived of the surprise attack  on Pearl Harbor. He then sought to destroy the remnants of the U.S. fleet,  principally its aircraft carriers, but the Japanese lost the resulting Battle  of Midway in June 1942. His campaign in the Solomon Islands was also  unsuccessful. He was killed when the U.S. (which had broken the Japa�  nese communications codes) discovered his whereabouts and shot down  his plane over Bougainville island.</p><p>Yamasee Vya-ms-seX War (1715-16) Conflict between Indians and  American colonists. Indian resentment of colonial settlers and traders in  South Carolina led a group of Yamasee Indians to kill 90 whites in 1715.  Other tribes soon joined the Yamasee in their raids on trading posts and  plantations. Colonial military assistance from neighbouring colonies and  war supplies from New England helped end the raids. Many defeated  Indians escaped to Florida, where they joined runaway black slaves and  other Indians to form what later became known as the Seminole tribe.</p><p>Yamato Takeru Xya-'ma-to-ta-'ke-riiX Japanese folk hero who may  have lived in the 2nd century ad. The son of the 12th emperor, Keiko, he  was responsible for expanding the territory of the Yamato court. In stories,  he subdued two Kumaso warriors by disguising himself as a woman and  killing them while they were drunk. With a miraculous sword he then cut  away the burning grass fire set by the Ainu tribesmen and escaped. On the  plains of Tagi, he became ill, changed into a white plover, and disap�  peared. His tomb at Ise is known as the Mausoleum of the White Plover.</p><p>Yamazaki Ansai X'ya-ma-.za-ke-'an-.siX (b. Jan. 24, 1619, Kyoto,  Japan�d.

Early in life he was a Buddhist  monk, but he gradually rejected Buddhism in favour of Confucianism,  which he began to teach to thousands of students. He reduced Neo-  Confucianism to a simple moral code, which he then blended with native  Shinto religious doctrines. He equated Neo-Confucian principles and  theories with Shinto legends and divinity, creating a philosophical system  that took on greater authority than its sources possessed alone. His thought  was one of the sources of the extreme nationalism and emperor worship  that developed later in Japan.</p><p>Yamm X'yamX Ancient West Semitic deity who ruled the oceans, rivers,  lakes, and underground springs. At the beginning of time, Yamm was  awarded the divine kingship by El, the head of the pantheon. One day,  Yamm�s messengers requested that the gods send Baal to become Yamm�s  servant. Baal refused to go, and engaged Yamm in battle. After a furious  fight, Yamm was slain and the kingship was given to Baal. Yamm may  have been the same deity as Lotan (Hebrew: �Leviathan�), who was rep�  resented as a dragon or serpent.</p><p>Yamoussoukro X.ya-mti-'su-kroX Town (pop., 1995 est.: 110,000),  capital designate of Cote d�Ivoire.

It was a fishing village until the present city was founded  in the mid-1750s by King Alaungpaya; he developed it as a port. The  British occupied it 1824-26 during the First Anglo-Burmese War and again  took it in 1852 during the Second Anglo-Burmese War. After the British  annexation of all of Burma in 1886, Rangoon became the capital city.  During World War II the Japanese advanced on and occupied the city, and  it suffered considerable damage. It handles more than four-fifths of Myan�  mar�s foreign commerce.

Rising in the Tanggula Mountains in west-central  China, it flows southeast before turning northeast and then generally east  across south-central and east-central China to the East China Sea near  Shanghai. It is known as the Jinsha in its upper course. It is the world�s third  longest river, 3,915 mi (6,300 km) long. Its chief tributaries are the Yalong,  Min, Jialing, Han, and Wu rivers. Several large cities, including Shanghai,  Nanjing, Wuhan, and Chongqing, lie in the river�s basin, which is known  as the granary of China. Large ships can sail to Wuhan, and smaller vessels  can reach Yichang; it becomes harder to navigate above Yichang because of  the gorges that occur between Chongqing and Yichang. Work on the con�  troversial Three Gorges Dam Project �first discussed in the 1920s and pro�  moted in the 1950s by Mao Zedong �was inaugurated in 1994.

He was  part of the research team that first demonstrated that certain mutant genes  produce inactive proteins. Later, working with E. coli, he showed that the  sequence of the nitrogenous bases that form part of the structure of the  genetic material corresponds to the amino acid sequence of proteins.  Investigating the biochemical actions of suppressor mutations (changes in  a gene that reverse the visible effects of mutation in a second gene), he  found that suppression restored the ability to form an active enzyme in a  mutant that had previously produced an inactive protein.</p><p>Yanomami or Yanomamo South American Indians who live in the  remote forest of the Orinoco River basin in southern Venezuela and the  northern reaches of the Amazon River basin in Brazil. They are hunters  and gatherers who also grow crops in gardens by practicing shifting cul�  tivation. Their reputation as a fierce people perpetually at war has been  challenged since the late 20th century. Because their survival was threat�  ened by incursions of Brazilian miners, in 1991 the Brazilian government  set aside an area of 36,000 sq mi (93,000 sq km) as a homeland.</p><p>Yao Vyau\ Various Bantu-speaking peoples inhabiting southern Tanza�  nia, northern Mozambique, and southern Malawi.

It rises in south�  western Syria and flows southwest to its confluence with the Jordan River.  For most of its total course of about 50 mi (80 km), it forms the bound�  ary between Syria and Jordan. A major battle along the river between  invading Muslim Arabs and Byzantine forces in 636 ad established Mus�  lim dominance in Palestine. That dominance, broken only by the period  of the Crusades (1099-1291), lasted until World War I (1914-18). Since  the Six-Day War of 1967, the lower river valley has been under Israeli  control.</p><p>yarn Continuous strand of fibres grouped or twisted together and used  to construct textile fabrics. Yams are made from both natural and synthetic  fibres, in filament or staple form. Filament is very long fibre, including  the natural fibre SILK and the synthetic fibres. Most fibres that occur in  nature are fairly short, or staple, and synthetic fibres may be cut into short,  uniform lengths to form staple. Spinning is the process of drawing out  and twisting a mass of cleaned, prepared fibres. Filament yarns generally  require less twist than do staple yarns. More twist produces stronger yam;  low twist produces softer, shinier yam. Two or more single strands may  be twisted together to form ply yarn. Knitting yams have less twist than  weaving yams. Thread, used for sewing, is a tightly twisted ply yarn.</p><p>Yaroslav \y3-re-'slaf\ known as Yaroslav the Wise (b. 980�d. Feb.  2, 1054) Grand prince of Kiev (1019-54).

Yaws spreads  mainly by discharge from skin sores, not sexual activity. It is common in  children, who usually become immune. In the first stage, a skin sore starts  as a wartlike thickening, cracks open, leaks fluid, and bleeds easily. A  month or more later, multiple sores erupt. The third stage (much rarer  than in syphilis) involves destruction of skin, mucous membranes, and  bones. Penicillin cures early-stage yaws. Prevention requires isolation and  prompt treatment and personal and group hygiene.</p><p>Yayoi Vya-,y6i\ culture (c. 250 bc-c. ad 250) Prehistoric culture of  Japan subsequent to Jomon culture. It arose on the island of Kyushu and  spread northeastward across Honshu. The Yayoi people mastered bronze  and iron casting, wove hemp, and employed a Chinese method of wet-  paddy rice cultivation. Yayoi pottery is unglazed; early examples have  incised decorations, but pieces produced in the last stage of the period are  often undecorated. Chinese-style bronze mirrors and coins indicate con�  tact with Han-dynasty China.</p><p>YazTd \ya-'zed\ I (b. c. 645, Arabian Peninsula�d. 683, Damascus,  Syria) Second caliph (680-683) of the Umayyad dynasty.

Its adherents, numbering fewer than 100,000, are found in Iraq,  Turkey, Syria, Armenia, the Caucasus, and Iran. Most speak Kurdish.  They believe that they were created separately from the rest of human�  kind and segregate themselves from the rest of society. In Yazld! belief,  seven angels, subordinate to a supreme but uninvolved God, rule the uni�  verse. The belief that God restored the Devil to his position as chief of  the angels upon the Devil�s repentance has earned the Yazld! an unde�  served reputation as Devil worshipers. Their chief saint is Sheikh c AdI, a  12th-century Muslim mystic. Their name derives from YazId I (c. 645-  683), from whose supporters they may be descended.</p><p>Yazoo land fraud \ya-'zii\ (1795-1814) Scheme to sell land in Geor�  gia. After legislators were bribed to sell Georgia�s western land claims</p><p>around the Yazoo River to four land companies for $500,000, public anger  forced a newly elected Georgia legislature to rescind the act (1796) and  return the money. Much of the land had meanwhile been resold to third  parties, who refused the money and maintained their claim to the prop�  erty. The state ceded its claim to the U.S. in 1802. In 1810 the U.S.  Supreme Court ruled that the 1796 rescinding law was an unconstitutional  infringement on a contract. By 1814 the U.S. government assumed pos�  session of the territory and awarded the claimants over $4 million.</p><p>Yazoo \ya-'zii\ River River, west-central Mississippi, U.S. Formed by  the confluence of the Tallahatchie and Yalobusha rivers north of Green�  wood, Miss., it meanders 189 mi (304 km) south and southwest to join  the Mississippi River above Vicksburg.

This fractional number makes necessary the peri�  odic adjustment of days in any calendar that is to be kept in step with the  seasons. In the Gregorian calendar, a common year contains 365 days,  and every fourth year is a leap year of 366 days except for any year that  is divisible by 100 but not divisible by 400 (e.g., 1900 was not a leap  year).</p><p>Year 2000 bug See Y2K bug</p><p>yeast Any of certain economically important and usually single-celled  fungi (see fungus), most of which are classified as ascomycetes.

The types commonly  used in the production of bread, beer, and wine are selected strains of  Saccharomyces cerevisiae, the small cakes and packets used contain bil�  lions of individual yeast cells, each of which can ferment approximately  its own weight of glucose per hour. Dried yeast is 50% protein and is rich  in B vitamins; brewer�s yeast is sometimes taken as a vitamin supple�  ment. Some yeasts are mild to dangerous pathogens of humans and other  animals. Candida albicans, for example, irritates oral and vaginal linings,  and Histoplasma and Blastomyces cause persistent lung infections.</p><p>Yeats \'yats\, William Butler (b. June 13, 1865, Sandymount, Dublin,  Ire.�d. Jan. 28, 1939, Roquebrune-Cap-Martin, France) Irish poet, dra�  matist, and prose writer. The son of a well-known painter, Yeats early  developed an interest in mysticism and visionary traditions as well as in  Irish folklore, and both interests would continue to be sources of poetic  imagery for him. His early volumes include the poetry volume The Wan�  derings of Oisin (1889) and the essay collection The Celtic Twilight  (1893). In 1889 he fell in love with Maud Gonne, a brilliant, beautiful Irish  patriot who inspired his involvement in Irish nationalism but did not recip�  rocate his feelings. With Lady Augusta Gregory and others, he founded  the theatre that became the Abbey Theatre; throughout his life he would  remain one of its directors. He contributed plays to its repertoire, including  The Countess Cathleen (1899), On Baile�s Strand (1905), and Deirdre  (1907). His poetry changed decisively in the years 1909-14: the other�  worldly, ecstatic atmosphere of the early lyrics cleared and his work  gained in concreteness and complexity, often dealing with political  themes, though his interest in mysticism and his passion for Maud Gonne  continued unabated. With Responsibilities (1914) and The Wild Swans at  Coole (1917) he began the period of his highest achievement. Some of his  greatest verse appeal's in The Tower { 1928), The Winding Stair (1929), and  Last Poems (1939). The individual poems of the latter are largely held  together by the system of symbolism he developed in A Vision (1925),  which used astrological images to link individual psychology with the  larger patterns of history. Yeats was a member of the Irish Senate (1922-  28). He won the Nobel Prize for Literature in 1923, and he is regarded by  some as the greatest English-language poet of the 20th century.</p><p>Yeh-lii Ch'u-ts'ai See Yelu Chucai</p><p>Yekaterinburg \yi-,ka-ti-ran-'hQrk\ formerly (1924-91) Sverd�  lovsk \sfyird-'lofsk\ City (pop., 2001 est.: 1,256,900), west-central Rus-</p><p>Yarrow (Achillea millefolium variety  lanulosa )</p><p>DENNIS E.

It grew as the centre for  all the ironworks of the Ural Mountains region, and its importance  increased with the building of a highway (1783) and the Trans-Siberian  Railroad. It achieved notoriety as the place where Tsar Nicholas II and his  family were held prisoner and executed by the Bolsheviks in 1918. In 1924  it was renamed Sverdlovsk in honour of Yakov Sverdlov.

Abrupt onset of headache, backache, fever, nausea, and  vomiting is followed by either recovery with immunity or by higher fever,  slow pulse, and vomiting of blood. Patients may die in a week. Jaundice is  common (hence the name). One of the world�s great plagues for 300 years,  it is caused by a virus transmitted by several species of mosquitoes. Carlos  Finlay suggested and Walter Reed proved this means of spread, leading to  near elimination of the disease through mosquito control (see William Gor-  gas). Treatment consists of supportive care, particularly fever reduction.  Control of mosquitoes near cities and live-virus vaccines�developed by  Max Theiler (1899-1972), who won a 1951 Nobel Prize for his work�  have made yellow fever completely preventable.</p><p>yellow jacket Any of 35-40 species (genus Dolichovespula or Vesp-  ula ) of social wasps, principally of the Northern Hemisphere, named for  the black bands on its yellow abdomen. They differ from other wasps in  having their wings folded longitudinally when at rest. Dolichovespula  species typically build exposed nests. Vespula species build concealed  nests underground or in protected cavities; when a nest is stepped on, the  colony may erupt in an angry, stinging swarm. Nest size varies widely;  some nests can be held in one hand, whereas nests in warmer climates  may weigh half a ton.</p><p>yellow journalism In newspaper publishing, the use of lurid features  and sensationalized news in newspaper publishing to attract readers and  increase circulation. The phrase was coined in the 1890s to describe tac�  tics employed in the furious competition between two New York papers,  Joseph Puutzer�s World and William Randolph Hearst�s Journal. When  Hearst hired away from Pulitzer a cartoonist who had drawn the  immensely popular comic strip �The Yellow Kid,� another cartoonist was  hired to draw the comic for the World ; the rivalry excited so much atten�  tion that the competition was dubbed yellow journalism. Techniques of  the period that became permanent features of U.S. journalism include  banner headlines, coloured comics, and copious illustrations.</p><p>yellow poplar See tulip tree  Yellow River See Huang He</p><p>Yellow Sea Chinese Huang Hai Vhwaq-'hlX Large inlet of the west�  ern North Pacific Ocean, between northeastern China and the Korean  peninsula.

Two major arms of it are the Bo Hai (northwest) and Korea Bay  (north). Excluding the Bo Hai, it has an area of about 161,000 sq mi  (417,000 sq km) and a maximum depth of 338 ft (103 m). It derives its  name from the colour of the silt-laden water discharged into it by major  Chinese rivers, including the Liao and the Huang He (Yellow River), both  of which flow into the Bo Hai. Leading port cities include Qingdao and  Dalian in China, Inch'on in South Korea, and Namp�o in North Korea.</p><p>Yellow Turbans Chinese secret society founded during a time of pes�  tilence (2nd century ad).

Russian politician and president of Russia (1990-99). After  attending the Urals Polytechnic Institute, he worked at construction  projects in western Russia (1955-68). He became Communist Party leader  in Sverdlovsk in 1976, and he was an ally of Mikhail Gorbachev. Gor�  bachev later charged Yeltsin with eliminating corruption in the Moscow  party organization, and as first secretary (mayor) of Moscow (1985-87)  he proved a determined reformer. His criticism of the slow pace of reform  led to a break with Gorbachev, and Yeltsin lost his position. In 1989 he  was elected to the new Soviet parliament by a landslide, then became  president of the Russian Republic (1990) and resigned from the Commu�  nist Party. In 1991 he won the presidency again in the first popular elec�  tion in Russian history.

Currency: Yemeni rial. From the Gulf of Aden and the Red  Sea, a narrow coastal plain leads to highlands that cover most of the coun�  try. The northern region extends into the southern and southwestern Rub'  al-Khali desert. Mineral resources include iron ore, salt, petroleum, and  natural gas, all of which are exploited. Agriculture is important; industries  include petroleum and salt production. Yemen is a republic with two leg�  islative houses; its head of state is the president, and the head of govern�  ment is the prime minister. Tribal affiliations remain strong and directly</p><p>affect local and national policy. Yemen was the home of ancient Minaean,  Sabaean, and Himyarite kingdoms. The Romans invaded the region in the  1st century ad. In the 6th century it was conquered by Ethiopians and Per�  sians. Following the adoption of Islam in the 7th century, it was ruled nomi�  nally under a caliphate. The Egyptian AyyGbid dynasty ruled there in the late  12th-early 13th century, after which the region passed to the Rasulids.  From c. 1520 through 1918 the Ottoman Empire maintained varying degrees  of control, especially in the northwestern section. A boundary agreement  was reached in 1934 between the northwestern territory (controlled by a  local religious leader), which subsequently became the Yemen Arab  Republic (North Yemen), and the southeastern British-controlled territory,  which subsequently became the People�s Democratic Republic of Yemen  (South Yemen). Relations between the two Yemens remained tense and  were marked by conflict throughout the 1970s and �80s. The two officially  united as the Republic of Yemen in 1990. Its 1993 elections were the first  free, multiparty general elections held in the Arabian Peninsula, and they  were the first in which women participated.

Russian poet. The  descendant of Ukrainians exiled to Siberia, he grew up in Moscow and  in the small town that is the setting of his first important narrative poem,  Zima Junction (1956). He became the spokesman for the post-Stalin gen�  eration of Russian poets with his internationally publicized demands for  greater artistic freedom, which signaled an easing of Soviet control over  artists in the late 1950s and �60s. He revived brash, slangy language and  traditions such as love lyrics and personal lyrics, frowned upon under  Stalinism. His poem �Baby Yar� (1961) was an attack on lingering Soviet  anti-Semitism; his most ambitious cycle of poems is Bratsk Station  (1966). He became famous worldwide for his passionate recitations.</p><p>yew Any of about eight species of ornamental evergreens in the genus  Taxus, family Taxaceae (the yew family), distributed throughout the  Northern Hemisphere. Two species are always shrubby, but the others may  reach heights of 77 ft (25 m). The plants have many branches, covered  with needlelike leaves. Yew wood is hard, fine-grained, and heavy, with  white or creamy sapwood and amber to brown heartwood. Once popular  for cabinetwork, implements, and archery bows, it is used more today for  articles either carved or turned on a lathe. Other trees called yew but not  in this family are the plum-yew (family Cephalotaxaceae) and Prince  Albeit yew (family Podocarpaceae).</p><p>Yezhov \yi-'zhof\, Nikolay (Ivanovich) (b. 1895, St. Petersburg,  Russia�d. after January 1939) Soviet secret-police chief. He joined the  Communist Party in March 1917 and was a political commissar in the  Red Army during the Russian Civil War. Thereafter he rose through politi�  cal posts, and by 1927 he was a functionary for the Moscow party�s cen�  tral committee and a favourite of Joseph Stalin. He became a member of  the party�s Central Committee (1934) and succeeded Genrikh Yagoda as  chief of the Soviet security police, or NKVD (1936). He instituted the  most severe stage of the Great Purge (see purge trials), known as Yezhovsh-  china. By 1938 he had become the object of Stalin�s suspicions and was  replaced by Lavrenty Beria as head of the NKVD. He disappeared in 1939  and was probably executed.</p><p>Yggdrasill Vig-dro-.siL In Norse mythology, the world tree.

He helped shape the character of Korean  Confucianism through his creative interpretation of Zhu Xi�s teaching. His  To Become a Sage: The Ten Diagrams on Sage Learning, an aid for edu�  cating the king, offered a depiction of all the major concepts in Song-  dynasty learning. He elevated the level of Confucian dialogue to a new  height of intellectual sophistication through his correspondence with Ki  Taesung (1527-72). In their so-called four-seven debate, they discussed  the relationship between Mencius�s four basic human feelings (commis�  eration, shame, modesty, right versus wrong) and seven emotions.</p><p>Yi Song-gye Vye-'surj-'gyeV or T'aejo Vtl-'j6\ (b. 1335�d. 1408)  Founder of the Korean Choson dynasty (1392-1910). A military leader in  the Koryo dynasty, he rose through the ranks by battling invading forces.  He defeated his rivals and drove out the last king of the Koryo dynasty,  taking the throne in 1392. He established his capital at Hanyang (now  Seoul). He and his successors redistributed land, which had been con�  centrated in the hands of a few high-ranking bureaucrats, throughout the  various levels of officialdom. In a break with the past, he made Neo-  Confucianism the state religion, replacing Buddhism. Farming was made  the centre of the economy. In foreign relations, he maintained a close  relationship with China�s Ming dynasty.</p><p>Yi Sun-shin Vye-'sim-'shinX (b. April 28, 1545, Seoul, Korea�d. Dec.  16, 1598, off Noryang) Korean admiral and national hero. He worked on  developing the kobukson (�turtle ship�), thought to be the first ironclad  battleship. As a result of Yi�s preparations, his forces, unlike most of the  Korean military, were ready to fight when the Japanese under Toyotomi  Hideyoshi invaded in 1592. His sea victories effectively cut off the Japa�  nese troops in Korea from their supplies. In 1597 he was falsely accused  of disloyalty and demoted to the rank of common soldier. When the Japa�  nese launched a second invasion and largely destroyed the Korean navy,  Yi was reinstated and soon restored Korea�s control of the seas. He was  killed by a stray bullet as he pursued the retreating Japanese.</p><p>Yibin Ye -'bin\ or l-pin conventional Suchow Ysii-'joV City (pop., 2003  est.: 312,462), southern Sichuan province, south-central China. It is  located at the junction of the Min and Yangtze (Chang) rivers. A county  administration was set up there in the 2nd century bc. It first received the  name Yibin in ad 742. The Chinese hold expanded there during the Song  dynasty (960-1279). By the Qing dynasty (1644-1911) it was Xuzhou  (Hsii-chou) superior prefecture, known to Europeans as Suifu. In 1912 it  reverted to Yibin. In 1913 steamship communication with Chongqing was  opened, and Yibin grew into a major collection and distribution centre. It  has long been known for its salt deposits, which now supply a large  chemical plant.</p><p>Yichang \'e-'chaq\ or l-ch'ang City (pop., 1999 est.: 481,277), west�  ern Hubei province, east-central China. An ancient city, it is located at the  head of navigation on the Yangtze River (Chang Jiang), below the entrance  to the gorges of the Daba Mountains. As the gateway to the rich prov�  ince of Sichuan, it was often disputed during times of Chinese political  turmoil. It was made a treaty port for foreign trade in 1877; a Western  quarter grew beside it, and many Western commercial firms established  branches there. It was occupied by the Japanese and badly damaged dur�  ing World War II, but the city and its shipyards have been rebuilt. It is  now an industrial centre and a distribution point for the region�s manu�  factured goods.</p><p>Yiddish drama Productions of the professional Yiddish theatre. Euro�  pean Jewish drama originated in the Middle Ages, when dancers and jest�  ers entertained at Purim celebrations. By the 16th century, these  entertainments had become elaborate plays performed in Yiddish, the lan�  guage of the majority of central and eastern European Jews. The profes�  sional Yiddish theatre dates from 1876, when Abraham Goldfaden (1840-</p><p>1908) wrote a well-received musical sketch in Romania and organized a  troupe to perform his songs and plays. In 1883 anti-Semitic laws in Rus�  sia that forbade Yiddish plays compelled many actors and playwrights to  immigrate to England and the U.S. The playwright Jacob Gordin (1853�</p><p>1909) brought new material and adaptations to the U.S. Yiddish theatre,  including The Jewish King Lear (1892), starring Jacob P. Adler, founder  of a family of Yiddish- and English-speaking actors. In 1918 Maurice  Schwartz founded and directed the Yiddish Art Theatre, which trained  actors such as Jacob Ben-Ami and Muni Weisenfreund (later known as  Paul Muni). World War II destroyed most Yiddish culture in eastern  Europe, and by the late 20th century only a few Yiddish theatres survived  in New York City, London, Bucharest, and Warsaw.</p><p>Yiddish language Language of Ashkenazic Jews and their descen�  dants (see Ashkenazi), written in the Hebrew alphabet. Yiddish developed  from southeastern dialects of Middle High German carried into central  and eastern Europe beginning in the 12th century; it has been strongly  influenced by Hebrew and Aramaic, from which it draws 12-20% of its  lexicon. The isolation of eastern European speakers from High German  and their exposure to Slavic languages, particularly Polish and Ukrainian,  led to a primary distinction between West and East Yiddish dialects. From  the late 18th century most Jews remaining in central Europe gave up Yid�  dish in favour of German; it has now virtually died out. East Yiddish dia�  lects differ markedly in realization of vowels; there are central,  northeastern, and southeastern dialects. A flourishing literary language in  the 19th and early 20th century, Yiddish declined dramatically due to sup�  pression, massive migration, assimilation, and Nazi genocide. The lan�  guage nevertheless continues to flourish among the ultra-Orthodox  Hasidim in numerous countries and among secular students of Yiddish at  leading universities, including Columbia University (New York), Hebrew  University (Jerusalem), McGill University (Montreal), the University of  Oxford, and the University of Paris. Yiddish is spoken by three million  people worldwide.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2096 I Yijing &#x25BA; Yongjo</p><p>Yijing or I Ching Ve-'jiqX Chinese "Book of Changes" Ancient  Chinese text, one of the Five Classics of Confucianism.

In one legend, Yima became  king in a golden age in which need, death, disease, aging, and extremes  of temperature were banished from the earth because of his virtue. This  golden age ended when Ahura Mazda foretold a terrible winter. Yima was  instructed to build an underground domain, take in the best individuals  from each species to preserve their seed, and then reemerge after the win�  ter to repopulate the earth.

It is  located near the western end of the Great Wall. Originally a county in the  1st century bc, it became the capital of the Xi Xia dynasty in 907 ad. In  1227 it came under the Mongol dynasty and was later under the Ming and  the Qing dynasties. In 1928 it became the capital of the newly formed  Ningxia province. In 1954 when Ningxia province was abolished, the city  became part of Gansu province. With the establishment of the Ningxia  autonomous region in 1958, Yinchuan once again became the capital.  Largely nonindustrial, it is the chief agricultural market and distribution  centre for the area.</p><p>ylang-ylang or ilang-ilang V.e-.laq-'e-.laqV South Asian evergreen  tree ( Cananga odorata ) of the custard apple family.

Tall (77 ft, or 25 m) and  slim, it has smooth bark and is covered year-round with drooping, long-  stalked, rich-scented flowers that have six narrow, greenish-yellow petals.  The pointed oval leaves have wavy edges. Clustered, oval black fruits  hang from long stalks. Leis are made from the blooms, and a delicate  fragrance is distilled from the flowers. The woody ylang-ylang vine ( Art -  abotrys odoratissimus), in the same family, is popular on trellises and  patios in warm, moist climates.</p><p>YMCA in full Young Men's Christian Association Nonsectarian,  nonpolitical Christian lay movement that aims to develop high standards  of Christian character among its members. It originated in London in 1844  when 12 young men formed a club to improve the spiritual condition of  young tradesmen. The first U.S. club was formed in Boston in the 1850s.  YMCA programs include sports and physical education, camping, formal  and informal education, and citizenship activities. It also runs hotels, resi�  dence halls, and cafeterias. National councils are members of the World  Alliance of YMCAs (established 1855), headquartered in Geneva. The  YMCA was charged with sponsoring educational and recreational facili�  ties in prisoner-of-war camps by the Geneva Convention of 1929. It now  operates in dozens of countries. The Young Women�s Christian Associa�  tion (YWCA) was founded in Britain (1877) to address the needs of  women from rural areas who came to the cities to find work; in the U.S.  (founded 1906), it has championed racial equality. The Young Men�s and  Young Women�s Hebrew Association (YM-YWHA) developed in the  mid-19th century from Jewish men�s literary societies in the U.S. and now  exists in some 20 other countries worldwide.</p><p>Ymir See Aurgelmir</p><p>Yoga One of the six orthodox systems (darshans) of Indian philosophy,  which has had widespread influence on many schools of Indian thought.  It is better known through its practical aspect than its intellectual content,  which is largely based on the philosophy of Samkhya. Holding that the</p><p>evolution of the world occurred in stages. Yoga attempts to reverse this  order so that a person reenters his or her state of purity and conscious�  ness. Generally, the Yoga process involves eight stages, which may require  several lifetimes to pass through. The first two stages are ethical prepa�  rations emphasizing morality, cleanliness, and devotion to God. The next  two stages are physical preparations that condition the body to make it  supple, flexible, and healthy; the physical aspects of Yoga have been most  successfully popularized in the West. The fifth stage involves control of  the mind and senses to withdraw from outward objects. The remaining  three stages entail the cultivation of increasingly concentrated states of  awareness, which will ultimately lead to release from the cycle of rebirth.

It rejects the complete realism of  Theravada Buddhism and the practical realism of the Madhyamika school,  preferring a more complicated position in which the reality perceived by  humans does not exist but only appears to do so by virtue of the capacity  of the mind to perceive patterns of continuity and regularity. Yogacara  emerged in India about the 2nd century and was introduced into China in  the 7th century by Xuanzang. It was transmitted to Japan in the mid-7th  century as Hosso.</p><p>yogurt Semisolid, fermented, often flavoured milk food. Yogurt is known  and consumed in almost all parts of the world. It is traditionally made by  adding common strains of Streptococcus and Lactobacillus bacteria to raw  milk. The culture is produced by taking a portion of a previous batch. In  modern commercial yogurt making, a blend of concentrated sterilized  milk and milk solids is inoculated with the two bacteria; sometimes L.  acidophilus or a lactose-fermenting yeast is also added. The product is  then incubated four or five hours at 110-112 �F (43-44 �C) until curd  forms. Various flavours and sweetening may be added.</p><p>Yoho National Park National park, southeastern British Columbia,  Canada.

He was enfeoffed as the Prince of Yan (the  region around present-day Beijing) and spent his youth patrolling the  northern frontier and keeping the Mongols fragmented. When his nephew  succeeded to the throne, Zhu Di rebelled and became emperor in 1402.  As emperor, he worked to extend China�s sway. He sent out ships of  exploration, most notably under Zheng He; these returned with envoys  bearing tribute to acknowledge China�s overlordship. He became the only  ruler in Chinese history to be acknowledged suzerain by the Japanese. A  foray into Annam (now Vietnam), which he attempted to incorporate into  China, led to years of guerrilla warfare. He five times led large armies  north to the Gobi Desert, forestalling the creation of a Mongol confed�  eration that might have threatened China. He transferred China�s capital  from Nanjing to Beijing. He built the Forbidden City and repaired the  Grand Canal so that Beijing could be provisioned without relying on sea  transport.

Yorubaland remains divided into politically autonomous king�  doms, each centred on a capital city or town and headed by a hereditary  king ( oba ), traditionally considered sacred. Most Yoruba men are farm�  ers, growing yams, corn, and millet as staples; cocoa is a cash crop.  Yoruba women control much of the complex market system. Craftsmen  work in blacksmithing, weaving, leatherworking, glassmaking, bronze  casting, and ivory- and wood-carving. Though some Yoruba are now  Christians or Muslims, belief in their traditional religion continues, and  it remains alive, too, in the New World countries to which may Yoruba  were transported to work as slaves (see Candomble; Macumba; Santeria;  vodun). The Yoruba language has an extensive literature of poetry, short  stories, myths, and proverbs.</p><p>Yorubaland Vyor-u-bo-.landN Area of western Africa, in present-day  Nigeria. It once comprised several states headed by individual Yoruba  kings. It flourished for centuries before disputes between minor rulers,  difficulties in maintaining trade routes, and invasions led to its decline,  beginning in the late 18th century. Oyo, Ife, Ibadan, and Oshogbo are  cities with historical Yoruba background.</p><p>Yosemite \yo-'se-m3-te\ Falls Two waterfalls, Yosemite National Park,  central California, U.S. Formed by creeks tumbling into the Yosemite  River valley, the upper falls drop 1,430 ft (436 m) and the lower, 320 ft  (98 m).

Late in the war (June  1945) he was arrested for attempting to force an early Japanese surren�  der; he was not freed until the start of the Allied occupation (September).  He first became prime minister in 1946. Between 1946 and 1954 he  formed five separate cabinets, guiding Japan back to economic prosper�  ity and setting a course for postwar cooperation with the U.S. and Europe.  In 1951 he negotiated the peace treaty that ended World War II; he also  negotiated a security pact between Japan and the U.S. He retired from  politics in 1955.

Aug.  29, 1877, Salt Lake City, Utah) U.S.  religious leader, second president of  the Mormon church. He settled in  Mendon, N.Y., in 1829 and was bap�  tized into Joseph Smith�s Church of  Jesus Christ of Latter-day Saints in  1832. In 1834 he joined the Mor�  mons in Missouri, and when they  were driven out in 1838, he orga�  nized their move to Nauvoo, Ill. He  established a Mormon mission in  England in 1839. After Smith�s mur�  der in 1844, Young took over the  church. He led the persecuted Mor�  mons from Illinois to Utah (1846�</p><p>48), choosing the site of Salt Lake  City for the new Mormon headquar�  ters. Elected president of the Mor�  mons in 1847, he became governor  of the provisional state of Deseret in  1849 and of the territory of Utah in  1850. His dictatorial autonomy and legalization of polygamy led Pres.  James Buchanan to replace him as governor in 1857 and send the army to  assert federal supremacy in the so-called Utah War, but Young remained  head of the Mormon church until his death. He took more than 20 wives  and fathered 47 children.</p><p>Young, Coleman (b. May 24, 1918, Tuscaloosa, Ala., U.S.�d. Nov.  29, 1997, Detroit, Mich.) U.S. politician.

He later cofounded the National Negro Labor Council, which  he disbanded in the 1950s to avoid turning over its membership list dur�  ing an investigation by the House Un-American Activities Committee. He was  elected to the Michigan senate in 1964, and in 1968 he became the Demo�  cratic National Committee�s first African American member. As mayor of  Detroit (1973-93), he focused on revitalizing the crime-ridden city by  attracting new businesses and reinforcing the police department. He  retired after an unprecedented five terms.</p><p>Young, Cy orig. Denton True Young (b. March 29, 1867, Gilmore,  Ohio, U.S.�d. Nov. 4, 1955, Newcomerstown, Ohio) U.S. baseball  pitcher. Young, 6 ft 2 in. (1.88 m) tall, was a powerful right-handed thrower.  His dominating fastball earned him the nickname �Cy,� short for  �cyclone.� He began his major league career in 1890 with the Cleveland  Indians (National League); after his Cleveland years (1890-98), he pitched  for the St. Louis Cardinals (1899-1900), the Boston Red Sox (1901-08),  the Cleveland Indians again (American League, 1909-11), and the Boston  Braves (1911). In each of 16 seasons he won more than 20 games; in five  he won more than 30. Though many early records are in dispute, he won  more major league games (509 or 511) than any other pitcher in history.  Among his other records are games started (816 or 818), completed starts  (750 or 751), and innings pitched (7,356 or 7,377). In 1904 he pitched the  first perfect game (no player reaching first base). The annual Cy Young  Award, instituted in 1956, originally honoured the best major league  pitcher; since 1967 it has been given to the best pitcher in each league.</p><p>Young, Lester (Willis) (b.

He began his  career as a folksinger in Winnipeg  and later moved to Los Angeles, Calif., U.S., where he formed the rock  group Buffalo Springfield with Stephen Stills. In 1968 he released a solo  album; in 1969 he joined Stills, David Crosby, and Graham Nash, to form  Crosby, Stills, Nash and Young. His high-pitched, nasal vocals were  instantly recognizable in any band. With a new band, Crazy Horse, he had  great success with albums such as Harvest (1972) and Comes a Time  (1978). In the 1980s he experimented with rockabilly and electronic music.</p><p>Young, Thomas (b. June 13, 1773, Milverton, Somerset, Eng.�d.  May 10, 1829, London) English physicist. Trained as a physician, he  practiced medicine at St. George�s Hospital (from 1811 until his death)  but spent much of his time on scientific research. He was the first to  describe and measure astigmatism (1800-01) and the first to explain  colour sensation in terms of retinal structures corresponding to red, green,  and violet (1801). He established the principle of interference of light, thus  resurrecting the century-old wave theory of light (1801). He explained  capillarity independently of Pierre-Simon Laplace. Investigating elasticity,  he proposed Young�s modulus, a numerical constant that describes the  elastic properties of a solid undergoing tension or compression. His other  work included measuring the size of molecules and surface tension in liq�  uids. With J.-F. Champollion, he helped decipher the inscriptions on the  Rosetta Stone (1813-14).</p><p>Young Algerians Algerian nationalist group. Formed shortly before  World War I (1914-18), they were a loosely organized group of French-  educated workers in the modernized French sector. The Young Algerians  were �assimilationists,� willing to consider permanent union with France  on the condition that native Algerians be given the full rights of French  citizens. In the years following the war, such gradualist reformers found  themselves opposed by radical nationalists demanding complete indepen�  dence.

Inspired by European youth movements of the 1830s (see Young  Italy), the U.S. group was formed as a political organization in 1845 by  Edwin de Leon and George H. Evans. It advocated free trade, expansion  southward into the territories, and support for republican movements  abroad. It became a faction in the Democratic Party in the 1850s. Sen.  Stephen A. Dougas promoted its nationalistic program in an unsuccessful  effort to compromise sectional differences.</p><p>Young Italy Italian Giovine Italia Movement founded by Giuseppe  Mazzini in 1831 to work for a united, republican Italian nation. In contrast  to earlier independence movements of the Carbonari, Young Italy was to  be based on support from the Italian people, who would be educated in  their political role. To propagate his ideas, Mazzini published the journal  Giovine Italia (1832-34). The movement spread in northern Italy and by  1833 included more than 50,000 members. It staged revolts in the 1830s  and �40s, but it failed to win popular support for insurrection. In 1848  Mazzini replaced Young Italy with the Italian National Committee. After  1850 his influence declined as leadership of the movement for Italian uni�  fication passed to Camillo Benso, count di Cavour.

The second battle (April 22-May 25, 1915)  marked the Germans� first use of poison gas as a weapon. In the third and  longest battle (July 31-Nov. 6, 1917), also called the Battle of Pass-  chendaele, the British were initially successful in breaking through the  left wing of the German lines. The seasonal rains soon turned the Flanders  countryside into an impassable swamp, but Gen. Douglas Haig persisted  in his offensive. On November 6 Haig�s troops, including the Canadian  Corps, occupied the ruins of Passchendaele, barely five miles from the  start of the offensive.

He was forced to flee to Russia, where his son Alexander  Ypsilanti (1792-1828) became an officer in the Russian imperial guard.  As the leader of the secret Greek organization Philikf Etaireia (1820), he  promoted the cause of Greek freedom and led an unsuccessful attack on  the Turks at Dragasani (1821).

Genghis  Khan occupied northern China in 1215, but not until 1279 did Kublai Khan  take control of southern China. The Mongols established their capital at  Beijing (then called Dadu). They rebuilt the Grand Canal and put the  roads and postal stations in good order. Paper money, which had had lim�  ited circulation under the Song, came to be used throughout the empire.  Advances were made in astronomy, medicine, and mathematics, and trade  was carried out throughout the Mongol empire from the plains of eastern  Europe across the steppes to Mongolia and China. Many foreigners came  to China (notably Marco Polo), and many Chinese traveled to Iran, Rus�  sia, and even western Europe. The Chinese resented the Mongol conquer�  ors, whose governmental system discriminated against them. Chinese  artists demonstrated passive resistance by withdrawing and turning to  personal expression. Literati painting became popular; the novel devel�  oped, and new dramatic forms also appeared. Disputes over succession  weakened the central government from 1300 on, and rebellions were fre�  quent, many connected with secret societies such as the Red Turbans. The  dynasty was overthrown in 1368 by the future Hongwu emperor. See also  Ming dynasty.</p><p>Yuan Vywen, 'ywan\ River River, southeast-central China.

In 1885 he was made  Chinese commissioner at Seoul; his promotion of China�s interests con�  tributed to the outbreak of the Sino-Japanese War (1894-95). The war  destroyed China�s navy and army, and the task of training a new army fell  to Yuan. When his division was the only one to survive the Boxer Rebel�  lion (1900), his political stature increased. He played a decisive part in  China�s modernization and defense programs and enjoyed the support of  the empress dowager Cixi. On her death he was dismissed, only to be called  back following the overthrow of the Qing dynasty in 1911-12, when he  became the first president of the new republic; Sun Yat-sen had previously  served as the provisional president. Impatient with the new National  Assembly, he ordered the assassination of Song Jiaoren, leader of the  Nationalist Party in 1913. He quelled a subsequent revolt, but his efforts  to found his own dynasty (1915-16) failed.</p><p>yuca See cassava</p><p>Yucatan \yu-ka-'tan\ State (pop., 2000: 1,658,210), northern Yucatan  Peninsula, southeastern Mexico.

Yucatan occupied virtually the entire pen�  insula when it became a state in 1824, but the creation of the states of  Campeche (1858) and Quintana Roo (1902) from parts of Yucatan, as well  as later boundary changes, reduced it to its present size.

The area had long been home to many pre-Columbian  civilizations before Spanish explorer HernAn Cortes traversed its inland  portion in 1525. Spanish rule was subsequently established, but since that  time many independent Maya Indians have kept to its inland rural areas  and resisted the authority of the central government.

At the close of this yuga, the world will be destroyed, to be re�  created after a period of quiescence as the cycle resumes.</p><p>Yugoslavia Former federated country situated on the west-central Bal�  kan Peninsula of southern Europe. Between 1929 and 2003, three fed�  erations bore the name Yugoslavia (�Land of the South Slavs�). After the  Balkan Wars of 1912-13 ended Turkish rule in the Balkan Peninsula and  Austria-Hungary was defeated in World War I, a Kingdom of Serbs,  Croats, and Slovenes was established, comprising the former kingdoms of  Serbia and Montenegro (including Serbian-held Macedonia), as well as  Croatia, Bosnia and Herzegovina, Austrian territory in Dalmatia and Slo�  venia, and Hungarian land north of the Danube River. The Kingdom of  Yugoslavia, officially proclaimed in 1929 by King Alexander I and lasting  until World War II, covered 95,576 sq mi (247,542 sq km). The postwar  Socialist Federal Republic of Yugoslavia covered 98,766 sq mi (255,804  sq km) and had a population of about 24 million by 1991. In addition to  Serbia and Montenegro, socialist Yugoslavia included four other repub�  lics now recognized as independent states: Bosnia and Herzegovina,  Croatia, Macedonia, and Slovenia. The �third Yugoslavia,� inaugurated  on April 27, 1992, had roughly 45% of the population and 40% of the  area of its predecessor and consisted of the republics of Serbia and Mon�  tenegro, which in 2003 abandoned the name Yugoslavia and renamed the  country Serbia and Montenegro.</p><p>Historical map of Yugoslavia showing the boundaries of the  country from 1946 to 1992.</p><p>Yukaghir See Siberian peoples</p><p>Yukon or Yukon Territory Territory (pop., 2001 est.: 30,000), north�  western Canada. Bounded by Alaska, U.S., to the west, and the Canadian  Northwest Territories to the east and British Columbia to the south, its  capital is Whitehorse. Drained by the Yukon River system, it has some of  the highest mountains in North America, notably the Saint Elias Moun�  tains and Mount Logan, Canada�s highest peak. It was originally settled  by American Indians and the Inuit (Eskimo). The first European visitor  (1825) was British explorer John Franklin, who was seeking the North�  west Passage. Sporadic settlement occurred thereafter. The discovery of  gold in the 1870s later resulted in the Klondike gold rush. In 1898 it was  separated from the Northwest Territories and given territorial status. The  economic boost from the gold rush soon abated, and the exploitation of  other minerals expanded and continued throughout the 20th century. Its  economic mainstays, though, are government services and tourism.</p><p>Yukon River River, northwestern North America. Formed by the con�  fluence of the Lewes and Pelly rivers in southwestern Yukon Territory,  Can., it is 1,980 mi (3,190 km) long. It flows northwest across the Yukon  border into Alaska, then southwest across central Alaska to the Bering Sea.  It is the third longest river in North America; its entire course of 1,265  mi (2,035 km) in Alaska is navigable. It attracted attention following the  rich gold strikes in 1896 on one of its Canadian tributaries, the Klondike  River (see Klondike gold rush).</p><p>Yuma \'yu-ma\ Any of various North American Indian peoples living  mostly in California and Arizona, U.S. Their languages belong to the  Hokan language family. They once lived in the lower Colorado River val�  ley and adjacent areas in Arizona, California, and Mexico. The river Yuma  (including the Mojave, Yuma, and Maricopa) lived along the lower Colo�  rado and middle Gila rivers; the upland Yuma (including the Hualapai,  Havasupai, and Yavapai) inhabited western Arizona south of the Grand  Canyon. The river Yuma were primarily farmers; the upland Yuma also  practiced hunting and gathering. Both lacked settled villages. Yuma reli�  gion is characterized by belief in a supreme creator, faith in dreams, and  ritual use of song narratives. At the turn of the 21st century, they num�  bered more than 4,000.</p><p>Yun-nan See Yunnan</p><p>Yung-lo emperor See Yongle emperor</p><p>Yung-ning See Nanning</p><p>Yungang Yyuen-'gagN caves or Yun-kang caves Series of mag�  nificent Chinese Buddhist cave temples, created in the 5th century ad dur�  ing the Northern Wei dynasty period. There are about 20 major cave  temples and many smaller niches and caves, stretching for over half a  mile. They are among the earliest remaining examples of the first flow�  ering of Buddhist art in China. The predominant sculptural style is a syn�  thesis of various foreign influences, including Persian, Byzantine, and  Greek, with elements ultimately derived from the Buddhist art of India.</p><p>Yunnan Vyui-'nanV or Yun-nan Province (pop., 2002 est.: 43,330,000),  southern China. It is bordered by Vietnam, Laos, and Myanmar, Sichuan  and Guizhou provinces, and Guangxi and Tibet autonomous regions. It has  an area of 168,400 sq mi (436,200 sq km), and its capital is Kunming. Its  population is one of China�s most ethnically mixed, comprising more than  20 nationalities. The terrain is largely mountainous, especially in the north  and west. It is crossed by three major river systems�the Yangtze (Chang;  there known as the Jinsha), the Mekong, and the Salween �and is the  source of two others�the Xi (there known as the Nanpan and Hongshui)  and the Yuan. Because of its isolation, the region was independent dur�  ing the historical development of China. The Mongols overran it in the  13th century. In 1855-73 it was the scene of the great Panthay (Muslim)  rebellion. Part of the province was seized by the Japanese in World War  II. Yunnan is now noted for its agricultural production, especially of rice,  as well as for its extensive mining industry.</p><p>Yunnan See Kunming  YWCA See YMCA</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>2102 I Z particle &#x25BA; Zambia</p><p>Z particle Electrically neutral carrier of the weak force and the neutral  partner of the electrically charged W particle.

Located within a central pla�  teau, it is traversed by several mountain ranges; the state�s  average elevation is about 7,700 ft (2,350 m). Its mineral  wealth was discovered soon after the Spanish conquest,  and some of its mines date from the mid-16th century.</p><p>Agriculture, livestock raising, and meat processing are  also important to the economy.</p><p>Zacatecas City (pop., 2000: 113,947), capital of  Zacatecas state, Mexico. It lies in a deep, narrow ravine about 8,200 ft  (2,500 m) above sea level. Founded in 1548, two years after silver was  discovered in the area, it was given city status in 1585. Until the 19th  century, the mines around Zacatecas yielded one-fifth of the world�s sil�  ver. Mining is still important to the economy, but the city is also a com�  mercial and manufacturing centre and is noted for its cathedral.

Influenced by both Cubism and Classical Greek sculpture, he devel�  oped a unique figurative style featuring concave and convex forms, lines,  and parallel planes. During World War II he taught at New York City�s  Art Students League. His large bronze To a Destroyed City (1951-53), an  homage to Rotterdam, is regarded as a masterpiece. In 1950 he received  the grand prize for sculpture at the Venice Biennale, and in the 1960s he  received commissions for statues in Jerusalem, Amsterdam, and else�  where.</p><p>Zadokite Fragments See Damascus Document</p><p>Zaghlul \zag-'lul\, Sa�d (b.

He initially cooperated with the British  occupation of Egypt, but his attitude changed on his election to the Leg�  islative Assembly in 1912. Britain declared martial law, established a pro�  tectorate, and dissolved the assembly during World War I (1914-18), after  which he led a delegation (Arabic: wafd) that demanded recognition as  the people�s representatives and called for abolition of the British pro�  tectorate. When these requests were turned down, widespread disorder  broke out that was not quelled even when Zaghlul, who had been deported  to Malta, was brought back and was elected prime minister at the head  of the Wafd party in 1924. He resigned after a year of violent unrest but  later served as president of the Chamber of Deputies, where he was able  to exercise some control over his more extreme followers.</p><p>Zagreb \'za-,greb\ City (pop., 2001: 691,724), capital of Croatia. It was  first mentioned in 1093, when a Roman Catholic bishopric was established  there. In medieval times the area contained a civil and an ecclesiastical  settlement. Rivals until the 19th century, they were joined when a spate  of new building occurred and expanded onto the Sava River floodplain. At  the time of the Croatian national revival in the 19th century, Zagreb was  the centre of both a pan-Yugoslav movement and a Croatian independence  movement. During the civil war following Croatia�s secession from Yugo�</p><p>slavia in 1991, Zagreb sustained heavy damage. It is Croatia�s principal  industrial centre. It is also the seat of the Academy of Sciences and Arts  and of the University of Zagreb (1669).</p><p>Zagreus Vza-gre-os, 'za-gre-3s\ In Greek mythology, the son of Zeus and  his daughter Persephone. Zeus intended to make Zagreus his heir and  bestow on him unlimited power, but a jealous Hera urged the Titans to  attack the child. They tore Zagreus to pieces and consumed all but his  heart, which Athena managed to save and bring to Zeus, who swallowed  it. Zeus then begot a son with Semele, and this child, made from the heart  of Zagreus, was Dionysus.</p><p>Zaharias \z3-'har-e-3s\, Babe Didrikson or Babe Didrikson  orig. Mildred Ella Didrikson (b.

She  became a remarkable performer in basketball and track and  field and later a leading golfer. In 1930-32 she was a mem�  ber of the women�s All-America basketball team. During the  same period she also won eight events and tied in a ninth in  national championship competition in track and field. In the 1932  Olympics she won gold medals in the 80-m hurdles and javelin  throw; she was deprived of the high-jump gold medal for using a  then-unorthodox method. As a golfer from 1946, she  won numerous championships, including the U.S. and  British women�s amateur tournaments (1946, 1947)  and the U.S. Women�s Open (1948, 1950, 1954).</p><p>zaibatsu \zl-'bat-su\ Japanese "wealthy  clique" Large capitalist enterprises of pre-World War  II Japan, similar to cartels or trusts but usually orga�  nized around a single family. One zaibatsu might oper�  ate companies in many areas of economic importance; all zaibatsu owned  their own banks, which they used as a means for mobilizing capital. After  the war the zaibatsu were dissolved: stock owned by the parent compa�  nies was put up for sale and individual companies were freed from the  control of parent companies. After the signing of the peace treaty in 1951,  many companies began associating into what became known as enterprise  groups; these differed from zaibatsu primarily in the informal manner that  characterized policy coordination and in the limited degree of financial  interdependency between member companies. Modern-day keiretsu are  similar.</p><p>za'Im \za-'em\ Political leader, either an officeholder or power broker.

Zambia�s economy depends heavily on the pro�  duction and export of copper. Other important mineral resources include  lead, zinc, cobalt, coal, and gold. Agriculture also is important. There is  some manufacturing. Zambia is a republic with one legislative house; its  head of state and government is the president. Ancestors of the Tonga  reached the region early in the 2nd millennium ad, but other peoples from  Congo (Kinshasa) and Angola reached the country only in the 17th�18th  century. Portuguese trading missions were established early in the 18th  century. Emissaries of Cecil Rhodes and the British South Africa Company  concluded treaties with most of the Zambian chiefs during the 1890s. The  company administered the region known as Northern Rhodesia until 1924,  when it became a British protectorate. It was part of the Central African  Federation of Rhodesia and Nyasaland in 1953�63. In 1964 Northern  Rhodesia became independent as the Republic of Zambia.

Educated as a naval engineer, he combined a scientific career with writ�  ing. A chronic dissenter, he was a Bolshevik before the Russian Revolu�  tion of 1917 but disassociated himself from the party afterward. His ironic  criticism of literary politics kept him out of official favour. His most  ambitious work, the novel We (1924; banned in the Soviet Union until  1989), was the first anti-utopian novel and the literary ancestor of Aldous  Huxley�s Brave New World and George Orwell�s Nineteen Eighty-four.</p><p>Zande \'zan-de\ or Azande \o-'zan-de\ People of central Africa who  live in The Sudan, Congo (Kinshasa), and Central African Republic.

Zanzibar city (pop., 2002: 205,870), the island�s  principal port and commercial centre, is on the western side. Both Zan�  zibar and Pemba islands are believed to have once formed part of the  African continent. In the late 17th century, Zanzibar came under the con�  trol of Omani Arabs, and the sultan of Oman made Zanzibar city his capi�  tal in 1832. In 1861 Zanzibar was separated from Oman and became an  independent sultanate. Under Sultan Barghash (r. 1870-88), most of the  mainland territories were lost to European powers. In 1890 the British  proclaimed a protectorate over Zanzibar and Pemba islands. In 1963 the  sultanate regained its independence and became a member of the Com�  monwealth.

Under the patronage of the shogun Ashikaga Yoshimitsu,  Zeami joined with his father, Kan�ami (1333-84), to create the no theatre  in its present form. He is credited with about 90 (and most of the great�  est) of the approximately 230 plays in the present repertoire. In treatises  written as manuals for his pupils, notably Fushi kaden (1400-18; �The  Transmission of the Flower of Acting Style�), he set forth principles of  no theatre that were followed for centuries.</p><p>zebra Any of three species of black-and-white-striped equines that subsist  almost entirely on grass. Zebras stand 47-55 in. (120-140 cm) tall. The  Burchell�s zebra, or bonte quagga (Equus quagga ), of eastern and southern  African grasslands, has wide, widely spaced stripes. Grevy�s zebra ( E .  grevyi), of arid areas in Kenya, Ethiopia, and Somalia, has narrow, closely  spaced stripes and a white belly. The small mountain zebra (E. zebra), of  dry upland plains in Namibia and western South Africa, has a gridlike pat�  tern on the rump. Small zebra groups consisting of a stallion and several  mares and foals may coalesce into large herds but retain their identity.</p><p>Burchell's zebra, or bonte quagga (Equus quagga)</p><p>LEONARD LEE RUE III</p><p>zebra fish Any member of two unrelated groups of fishes: freshwater  species in the genus Brachydanio (family Cyprinidae) and saltwater spe�  cies in the genus Pterois (family Scorpaenidae). The zebra danio (Brachy�  danio rerio), a popular freshwater aquarium fish originally from Asia,  grows to about 1.5 in. (4 cm) long and has dark blue and silvery longi�  tudinal stripes. The distinctive saltwater zebra fishes (Pterois), used in  marine aquariums, have extremely large pectoral fins, numerous  extremely poisonous spines, and colourful vertical stripes. Some species  are more commonly known as lionfish and turkeyfish.</p><p>zebra mussel Either of two species of tiny mussels (genus Dreissena)  that are prominent freshwater pests. They proliferate quickly and adhere in</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>zebu &#x25BA; Zeno of Citium I 2105</p><p>great numbers to virtually any surface. The voracious mussels disrupt food  webs by wiping out phytoplankton, and their massive clustering on water-  intake valves and pipes, bridge abutments, and other structures can cause  severe commercial damage. They made their first known attack on Europe  in the early 19th century and were carried (probably in ship water ballasts)  to North America c. 1986; their invasion of all the Great Lakes has had  devastating effects on the lakes� native mussel and fish populations.</p><p>zebu See Brahman</p><p>Zechariah \,zek-9-'rI-9\ (fl. 6th century bc) One of the 12 Minor Proph�  ets of the Hebrew scriptures, whose prophecies are recorded in the book  of Zechariah. (The work is part of a larger book. The Twelve, in the Jew�  ish canon.) His visions concern the return of the Jews to Jerusalem after  the Babylonian Exile, the rebuilding of the Temple of Jerusalem, and the  world�s recognition of Israel�s God. The book also includes his apoca�  lyptic visions of the end of time.</p><p>Zedillo \sa-'de-yo\ (Ponce de Leon), Ernesto (b. Dec. 27, 1951,  Mexico City, Mex.) President of Mexico (1994-2000). Raised in a  working-class family, he joined Mexico�s ruling party in 1971 and earned  a Ph.D. in economics from Yale University. As secretary of the Ministry  of Programming and Budget, he controlled Mexico�s huge foreign debt,  reduced inflation, and balanced the budget. Elected president after the  assassination of the original PRI (Institutional Revolutionary Party) can�  didate, Luis Donaldo Colosio, he undertook reforms to reduce poverty,  root out corruption, and continue democratizing the electoral system. His  devaluation of the peso in 1994 led to an economic crisis that was turned  around with massive U.S. aid. A rebellion in Chiapas plagued his admin�  istration, which was charged with human-rights abuses in that region.</p><p>Zee, James Van Der See James Van Der Zee</p><p>Zeeman \'za-,man\ effect Splitting of a spectral line (see spectrum) into  two or more lines of different frequencies. The effect occurs when the light  source is placed in a magnetic field. It has helped identify the energy levels  in atoms; it also provides a means of studying atomic nuclei and electron  paramagnetic resonance (see magnetic resonance) and is used in measuring  the magnetic field of the Sun and other stars. It was discovered in 1896 by  Pieter Zeeman (1865-1943); he shared the second Nobel Prize for Physics  (1902) with Hendrik Antoon Lorentz, who had hypothesized that a magnetic  field would affect the frequency of the light emitted.</p><p>Zefat \'tse-,fat\ City (pop., 2004 est.: 27,300), northern Israel. Located  near Lake Tiberias (Sea of Galilee), it is one of the four holy cities of Juda�  ism. It was fortified in the 1st century ad by Flavius Josephus and in the  Middle Ages by the Crusaders (see Crusades). It was the seat of an impor�  tant school of Jewish mysticism (see Kabbala) in the 16th century, and it  became part of the modem State of Israel in 1948. It is now an artists�  colony, with an economy based on light industry and tourism.</p><p>Zeffirelli \,ze-f9-'re-le. Franco orig. Gianfranco Corsi (b.

After serving as Visconti�s assistant on films such as La  terra trema (1948), he turned to stage design. His major operatic produc�  tions, noted for their visual richness, began with LTtaliana in Algeri  (1952-53) and include Lucia di Lammermoor (1959) and La Boheme  (1963, 1981), among many others; he directed films of La traviata (1983)  and Otello (1986). His other films include The Taming of the Shrew  (1967), Romeo and Juliet (1968), Endless Love (1981), Jane Eyre (1996),  and Tea with Mussolini (1999).</p><p>Zeiss Vtsls,\ English \'zls\, Carl (b.

He later formed a partnership with the physicist and mathemati�  cian Ernst Abbe (1840-1905). The chemist Otto Schott developed about  100 new kinds of optical glass and numerous types of heat-resistant glass  for the company. After Zeiss�s death, Abbe donated the firm and his share  in the glassworks to the Carl Zeiss Foundation; in 1923 Schott added his  share in the glassworks.</p><p>Zemes mate \'ze-mes-'ma-te\ In Baltic religion, the female aspect of  nature and the source of all life. Together with Dievs, she stimulates and  protects the power of life. Libations of beer were offered to her at the  opening of every festival, and bread, ale, and herbs were buried in the  ground, thrown into rivers and lakes, or tied to trees in her honour. Her</p><p>various functions were eventually assumed by demigoddesses of forests,  fields, stones, animals, water, and, in the Christian era, by the Virgin Mary.</p><p>zemstvo Vzemst-v3\ plural zemstvos Rural elected assembly in the  Russian Empire. Established by Tsar Alexander II in 1864 to provide social  and economic services, the zemstvos became a liberal influence in impe�  rial Russia. The assemblies, formed at the district and province levels,  were composed of delegates representing the landed proprietors and the  peasant village communes. They expanded education, improved roads,  and provided health care. From the 1890s they agitated for constitutional  reform, and they stimulated activity in the Russian Revolutions of 1905  and 1917 (see Russian Revolution of 1905; Russian Revolution of 1917).  They were abolished after the Bolsheviks came to power. The term zem�  stvo also refers to a 16th-century institution for tax collection.</p><p>Zen Important school of Buddhism that claims to transmit the experience  of enlightenment achieved by the Buddha Gautama. Arising as Chan in  China in the 6th century (introduced by Bodhidharma), it divided into two  schools, the Southern school, which believed in sudden enlightenment,  and the Northern school, which believed in gradual enlightenment. By  the 8th century only the Northern school survived. Zen developed fully  in Japan by the 12th century and had a significant following in the West  by the later 20th century. Zen teaches that the potential to achieve enlight�  enment is inherent in everyone but lies dormant because of ignorance. It  is best awakened not by the study of scripture, the practice of good deeds,  rites and ceremonies, or worship of images, but by breaking through the  boundaries of mundane logical thought. Methods employed vary among  different schools and may emphasize the practice of zazen (in the Soto  school), the use of koans (in the Rinzai school), or the continual invoca�  tion of Amida (in the Obaku school; see Amitabha).</p><p>Zend-Avesta See Avesta</p><p>Zeng Guofan or Tseng Kuo-fan Vdzon-'gwo-'fanN (b.

March 12, 1872, Nanjing)  Chinese military leader most responsible for suppressing the Taping Rebel�  lion, thus staving off the collapse of the Qing dynasty. Having passed the  highest examinations in the Chinese examination system, Zeng entered the  Hanun Academy and worked successfully as a bureaucrat. In 1852 he was  asked to help combat the Taiping rebels, who had reached the Yangtze  River (Chang Jiang) valley and were threatening the dynasty�s survival.  The imperial troops being weak, Zeng and other members of the scholar-  gentry organized local militias. His army seized the rebels� supply areas  along the upper Yangtze and besieged and captured their capital, Nanjing,  in 1864. In 1865 he was called on to help suppress the Nian Rebellion; a  year later he asked that Li Hongzhang take over the campaign. See also  Zhang Zhidong.</p><p>Zenger, John Peter (b. 1697, Germany�d. July 28, 1746, New York,  N.Y.) German-born U.S. printer and journalist. He immigrated to New  York at age 13 and was indentured to a printer before starting his own  printing business (1726). In 1733 he began publishing the New York  Weekly Journal. Arrested for libel in 1734 for his attacks on the policies  of the colonial governor, he was acquitted on the grounds that his charges  were based on fact (a key consideration in libel cases since that time). It  was the first important victory for freedom of the press in Britain�s North  American colonies.</p><p>Zeno \'ze-no\ orig. Tarasicodissa (b. Isauria, Diocese of the East�d.  April 9, ad 491) Eastern Roman emperor (474-491). A military leader, he  married the daughter of Emperor Leo I (c. 466), and their son reigned  briefly as Leo II (474). On the boy�s early death, Zeno became emperor.  Obliged to flee to Isauria to escape a coup d�etat, he returned to Con�  stantinople in 476. He made peace with the Vandals in Africa, put down  a rebellion in Asia Minor (484), and persuaded the Ostrogoths to leave  the Eastern Empire by making Theodoric king of Italy (489). Seeking to  reconcile orthodox Christians and Monophysites, he caused a schism with  Rome (484-519).</p><p>Zeno of Citium Vze- l no... , si-sh(e-)3m\ (b. c. 335, Citium, Cyprus�d.  c. 263 bc, Athens) Greek philosopher, founder of Stoicism. He went to  Athens c. 312 bc and attended lectures by the Cynics Crates of Thebes  (fl. late 4th century bc) and Stilpon of Megara (c. 380-300 bc), as well  as lectures at the Academy. He began to teach in the Stoa Poikile (�Painted  Colonnade�), whence the name of his philosophy. His system included  logic, epistemology, physics, and ethics. He taught that happiness lies in  conforming the will to the divine reason, which governs the universe.

He was called by Aristotle the inventor of dialectic. He is  best known for his paradoxes (see paradoxes of Zeno). As a pupil and  friend of Parmenides, he took it upon himself to reply to those who asserted  that his master�s doctrine of �the one� (i.e., indivisible reality) was incon�  sistent (see monism); he tried to show that the assumption of the existence  of �the many� (i.e., a plurality of things in time and space) carried with  it more serious inconsistencies.</p><p>Zenobia \z9-'no-be-3\ in full Sepfimia Zenobia (d. ad after 274)  Queen of the Roman colony of  Palmyra (267/268-272). Her hus�  band, a Roman client ruler of  Palmyra, was assassinated after  recapturing several of Rome�s east�  ern provinces from the Persians. She  became her son�s regent but called  herself queen. In 269 she seized  Egypt and much of Asia Minor and  declared her independence from  Rome. Aurelian defeated her armies  and besieged Palmyra; she and her  son were captured and taken to  Rome (272), where she was paraded  in Aurelian�s triumph.</p><p>zeolite Vze-o-.lflA Any member of  a family of hydrated aluminosilicate  minerals that have a framework  structure enclosing interconnected  cavities occupied by large metal cat�  ions (positively charged ions)�  generally sodium, potassium,  magnesium, calcium, and barium�  and water molecules. The ease of  movement of ions and water within the framework allows reversible dehy�  dration and cation exchange, properties that are exploited in water soft�  eners and molecular sieves for pollution control, among other uses.</p><p>zeolitic facies y.ze-o-'li-tik-'fa-shezV One of the major divisions of the  mineral facies classification of metamorphic rocks, encompassing rocks that  formed at the lowest temperatures and pressures associated with regional  metamorphism.

(The work  is part of a larger book, The Twelve, in the Jewish canon.) He prophesied  in the reign of JosiAH, denouncing the worship of foreign gods, which  suggests that he preached before the reforms instituted by Josiah. His  dominant theme is the coming �day of the Lord,� a time of divine judg�  ment for Judah�s sins.</p><p>zeppelin Rigid airship of a type designed by the German builder Fer�  dinand, Graf (count) von Zeppelin (1838-1917). It was a cigar-shaped,  trussed, and covered frame supported by internal gas cells, below which  hung two external cars with an engine geared to two propellers. The first  zeppelin flew in 1900. In World War I zeppelins were used as bombers  by Germany. In 1928 the Graf Zeppelin inaugurated transatlantic flight  service; it had completed 590 flights by 1937, when the Hindenburg disas�  ter halted such flights.</p><p>zero Number and numeral of critical importance in mathematics. Zero is  known as the additive identity because adding it to any number does not  change the number�s identity, or value. The product of zero and any number  is zero; for most number systems the converse is true�that is, if the prod�  uct of two numbers is zero, at least one of them must equal zero. The latter  property is fundamental to the solution of nearly every problem in math�  ematics. Division by zero is undefined; efforts to deal with such divisions  led to calculus. Various punctuation marks were first used in Mesopotamia  beginning about 700 bc to indicate an empty space in positional notation,  but never at the end of a number�the difference between, say, 78 and 780  had to be understood from the context. Ptolemy first used 0, or the Greek</p><p>letter omicron �o,� as an empty placeholder, including at the end of a num�  ber, to express data in the Babylonian sexagesimal system in his astronomi�  cal treatise Almagest (c. 130 ad). The Hindu-Arabic numerals and treatment  of zero as a number developed between the 6th and 9th centuries in India.  Zero soon followed trade routes to China, the Islamic world, and Europe.</p><p>Zero in full Mitsubishi A6M Zero Japanese fighter aircraft of World  War II. A single-seat, low-wing monoplane made by Mitsubishi, it was  introduced in 1940, the 2,600th anniversary of the crowning of Japan�s  legendary first emperor, Jimmu, and named for the �zero-year� celebration.  It had a top speed of 350 mph (565 kph) at nearly 20,000 ft (6,000 m).  When it first appeared, it could outmaneuver every plane it encountered;  Allied fighters could not defeat it until 1943. Many Zeros became kami�  kaze craft in the war�s closing months.</p><p>zero-point energy Vibrational energy retained by molecules even at  a temperature of absolute zero. Since temperature is a measure of the  intensity of molecular motion, molecules would be expected to come to  rest at absolute zero. However, if molecular motion were to cease alto�  gether, the atoms would each have a precisely known location and veloc�  ity (zero), and the uncertainty principle states that this cannot occur, since  precise values of both position and velocity of an object cannot be known  simultaneously. Thus, even molecules at absolute zero must have some  zero-point energy.</p><p>Zeroual \zer-'wal\, Liamine (b. July 3, 1941, Batna, Alg.) President  of Algeria (1994-99). After a military education, he rose through the ranks  to become chief of land forces in 1989 and defense minister in 1993. In  1994 he was appointed transitional president by the military-dominated  High Council of State, which had taken over the government after elec�  tions were canceled in 1992 and Pres. Mohamed Boudiaf was assassinated.  Elected for a full term in 1995, he was replaced in 1999 by Abdelaziz  Bouteflika.</p><p>Zetkin Vtset-konV Clara orig. Clara Eissner (b.

She joined the Social Democratic Party in 1881,  and she later married a Russian revolutionary exile, Ossip Zetkin (1848�  89). From 1892 she edited the Socialist women�s newspaper Die Gleich-  heit (�Equality�) in Stuttgart. A friend of Vladimir Lenin and Rosa  Luxemburg, Zetkin was a cofounder of the Spartacists (1916) and later  joined the new Communist Party of Germany (1919). In 1921 she was  elected to the presidium of the Third International (see Comintern). Her  influence waned after Lenin�s death in 1924.</p><p>Zeus \'ziis\ In Greek religion, the chief deity of the pantheon, a sky and  weather god. His Roman counterpart  was Jupiter. Zeus was regarded as the  bearer of thunder and lightning, rain,  and winds, and his traditional  weapon was the thunderbolt. The son  of Cronus and Rhea, he was fated to  dethrone his father. He divided  dominion over the world with his  brothers Poseidon and Hades. As ruler  of heaven, Zeus led the gods to vic�  tory against the Titans. From his  home atop Mount Olympus, he dis�  pensed justice and served as protec�  tor. Known for his amorousness�a  source of perpetual discord with his  wife, Hera �he had many love  affairs with mortal and immortal  women, giving rise to numerous off�  spring, including Apollo, Ares, Arte�  mis, Athena, Dionysus, Helen,</p><p>Hephaestus, and Persephone.

Though none of his work survives, his  style and subject matter were recorded by ancient writers. He advanced  the trend toward illusionism through the use of shadow to produce a rudi�  mentary form of chiaroscuro. Apparently he was a panel painter rather  than a wall painter. He preferred small compositions, often a single fig�  ure; his subjects were gods and heroes and such genre figures as an old  woman, an athlete, and a still life.</p><p>Zenobia, portrait bust; in the Vatican  Museum, Rome</p><p>ANDERSON-GIRAUDON FROM ART RESOURCE</p><p>Zeus hurling a thunderbolt, bronze  statuette from Dodona, Greece, early  5th century bc; in the Staatliche Museen  zu Berlin, Germany</p><p>COURTESY OF THE STAATLICHE MUSEEN ZU BERUN,  ANTIKENABTEILUNG</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Zhang Daoling &#x25BA; Zheng He I 2107</p><p>Zhang Daoling or Chang Tao-ling Vjaq-'dau-'liqV (b. ad 34?, Pei,  Jiangsu province, China�d. 156?, Hanzhong) Founder and first patriarch  of organized religious Daoism. Zhang composed a Daoist work that  attracted many followers among Chinese and indigenous groups in  Sichuan. Like contemporary Daoists, he promised longevity and physical  immortality, but, unlike others, he emphasized the importance of religious  organization. He founded the Five Pecks of Rice movement. Zhang, his son,  and his grandson are known as the Three Zhangs. While the Daodejing  was the basic text, Zhang�s Xiang�er commentary interpreted it to suit the  organization�s needs.</p><p>Zhang Daqian or Chang Ta-ch'ien (b. May 10, 1899, Neijiang,  Sichuan province, China�d. April 2, 1983, Taipei, Taiwan) Chinese  painter and collector. As a young man, he meticulously studied and cop�  ied the works of ancient masters; he gained notoriety in Shanghai for his  forgeries. Zhang extended his career to the north in the late 1920s, when  he became active in the cultural circles of Beijing. He began to collabo�  rate with the well-known Beijing painter Pu Xinyu, and together they  became known as �South Zhang and North Pu.� In 1940 Zhang led a  group of artists to the caves of Mogao and Yulin for the purpose of copy�  ing their Buddhist wall paintings. The group completed over 200 paint�  ings, and the experience left Zhang with a repository of religious imagery.  During this period he became particularly known for his lotus paintings,  inspired by works from the Tang-Song era. In reaction to the political cli�  mate, Zhang left China in the early 1950s and traveled throughout the  world. He developed eye problems in the late 1950s, and, as his eyesight  deteriorated, he developed his mature splashed-colour ( pocai ) style. His  work in this style fetched the highest market prices for contemporary  Chinese paintings at international auctions of the time.</p><p>Zhang Juzheng Chang Chu-cheng Vjaq-'jii-'joqX (b. 1525, Jiang-  ling, Hubei province, China�d. 1582, Beijing) Powerful Chinese minis�  ter of the Ming dynasty under the Longqing and Wanli emperors. His  benevolent rule and strong foreign and economic policies are considered  to have brought the Ming dynasty to its peak. He is credited with cen�  tralizing government, limiting special privileges, and reclaiming tax-  exempt land.</p><p>Zhang Yimou Vjaq-'ye-'moV (b. Nov. 14, 1950, Xi�an, China) Chinese  film director. He began his film career as a cinematographer, and his work  for Chen Kaige�s The Yellow Earth (1983) helped launch the �Fifth Gen�  eration,� filmmakers who brought back sensuality and emotion to Chi�  nese movies. Zhang made his directorial debut with Red Sorghum (1987),  which starred Gong Li in the first of her acclaimed roles. Noted for his  technical mastery, he also directed films such as Ju Dou (1990), Raise the  Red Lantern (1991), The Story of Qiu Ju (1992), To Live (1994), and Hero</p><p>( 2002 ).</p><p>Zhang Zai or Chang Tsai Yjaq-'dzA (b. 1020, Chang�an, China�d.  1077, China) Realist philosopher of the Song dynasty.

Sept. 2,  1837, Xingyi, Guizhou province, China�d. Oct. 4, 1909) Chinese clas�  sicist and one of the foremost reformers of his time. From 1862 to 1882  he was a scholar and educational director; from 1882 to 1907 he rose from  a provincial to a national leader. He supported the dowager empress Cixi,  who in turn favoured him with many promotions. Concerned with reju�  venating China, he searched for a way for China to survive in the mod�  ern world that could accommodate Western knowledge but preserve  traditional ways. His attempt to launch China�s first iron-and-steel works  failed, but he later built a railway that extended from Hankou to near  Beijing, and he founded a mint, tanneries, tile and silk factories, and paper,  cotton, and wool mills. In response to China�s defeat in the Sino-Japanese  War, Zhang turned his attention to education, encouraging study abroad  for Chinese students, establishment of a school system, translation of  Western and Japanese books, and acquisition of knowledge from foreign  newspapers. He also urged that civil service examinations be abolished,  which occurred in 1905. See also Zeng Guofan.</p><p>Zhang Zuolin or Chang Tso-lin Vjaq-dzo-'linX (b.

After fighting in the Sino-Japanese War (1894-</p><p>95), Zhang organized a self-defense militia in his native district. By 1912  he was in command of a division, and he set out to dominate Manchuria  (northeastern China), relying on the tacit support of the Japanese, to whom  he granted concessions in Manchuria. In 1918 he became inspector gen�  eral of Manchuria�s three provinces, which he ruled as a virtually autono�  mous state. In 1920 he pushed south into China proper and in 1924 took  Beijing, but his troops had to abandon their position in the face of Chiang  Kai-shek�s 1927 Northern Expedition. Zhang was killed by a bomb planted  by Japanese extremists who hoped his death would provoke the Japanese  into occupying Manchuria.</p><p>Zhao Youqin (b.

He was one of the patriarchs of the northern branch  of the Quanzhen (�Complete Perfection�) sect of Daoism. His astronomi�  cal treatise Gexiang xinshu (�New Writing on the Symbol of Alteration�)  presents his cosmological theory featuring a flat Earth inside a spherical  Heaven, his explanation of the lunar and solar eclipses, and his experi�  ments with a camera obscura. The book also describes his methods of  remote surveying with gnomons to measure the distance from the Earth  to the Sun, the Moon, and the stars, as well as his procedure for calcu�  lating the value of n.

He joined the Bolsheviks in 1915 and  became a leading member of the Politburo (1939) and Communist Party  secretary in Leningrad. A close associate of Joseph Stalin, he formulated  the extreme anti-Western cultural policy known as �Zhdanovism� (1946),  which imposed strict government control on art and literature and soon  affected all intellectual activity in the Soviet Union. In 1947 he founded  the propaganda bureau Cominform.</p><p>Zhejiang Vjo-'jyaqN or Che-chiang conventional Chekiang Prov�  ince (pop., 2000 est.: 46,770,000), eastern China. With an area of 39,300  sq mi (101,800 sq km), it is bounded by the China Sea, Shanghai munici�  pality, and Fujian, Jiangxi, Anhui, and Jiangsu provinces; its capital is Hang�  zhou. It is one of China�s smallest provinces and one of the most densely  populated. Its northern part lies just south of the Yangtze River (Chang  Jiang) delta. Occupying parts of various kingdoms until the 13th century  ad, it was divided in the 1270s into eastern and western regions. Foreign  penetration began in the 1840s. After the Chinese revolution (1911-12),  it became a power base for the Nationalist Party of Chiang Kai-shek, who  was born in the province. Occupied by the Japanese during World War  II, it was little affected by the 1946-49 civil war. In addition to its agri�  cultural importance, it has a thriving fishing industry. Its hydroelectric  power plants have spurred more growth.</p><p>Zheng Chenggong or Cheng Ch'eng-kung Vjoq-'choq-'guqN or  Koxinga \kak-'siq-3\ (b. Aug. 28, 1624, Hirado, Japan�d. June 23,  1662, Taiwan) Chinese military leader of the late Ming and early Qing  dynasties. After the Ming dynasty fell to the Manchu, Zheng refused  Manchu offers of rank and power and launched a military campaign  against the new dynasty in 1659, taking a large force from his base in  Fujian province up the Yangtze River (Chang Jiang). Initial success turned  into failure, but, undaunted, Zheng took Taiwan from the Dutch in 1662  to use as a secure rear base area. Further glory was cut short by his death  later that year. He became a popular deity and cultural hero to the Chi�  nese on Taiwan, and even the Qing court honoured him as a paragon of  loyalty. In Japan the playwright Chikamatsu Monzaemon celebrated him  on the stage (Zheng had a Japanese mother), and in the 20th century both  Chinese communists and Nationalists embraced him as a national hero.</p><p>Zheng He or Cheng Ho Vjoq-'heV orig.

Located south  of the Huang He (Yellow River), it is an important rail centre. There were  Neolithic settlements in the area, and the Shang Bronze Age culture (fl.  c. 1500 bc) was centred there on a walled city. Zhou-dynasty tombs have  also been discovered. The city was first called Zhengzhou in ad 605, and  it has been known by that name virtually ever since. It achieved its great�  est importance in the 6th-12th centuries, when it was the terminus of a  canal that joined the Huang to the north. In the early 20th century it  became a rail junction and a regional agricultural centre. Since 1950 its  industrial base has greatly expanded, and its population has grown con�  siderably.</p><p>Zhivkov \ , zhiv-,kof\ / Todor (Khristov) (b. Sept. 7, 1911, Pravets,  near Botevgrad, Bulg.�d. Aug. 5, 1998, Sofia) Bulgarian politician. The  son of poor peasants, he drifted to the Bulgarian capital of Sofia in his  youth and, in the late 1920s, joined the Komsomol, the youth league of  the outlawed Communist Party. During World War II he organized a resis�  tance movement, and after the war, he held posts in the Soviet-sponsored  government, including head of the People�s Militia. He became first sec�  retary of the Bulgarian Communist Party in 1954, the youngest leader in  the Soviet bloc, then served as premier (1962-71) and president (1971�  89). He hewed closely to the Soviet line but encouraged industrialization  and improved the country�s living standard. When democratization  reached Bulgaria, Zhivkov resigned (1989). Convicted of embezzlement,  he was sentenced to house arrest in 1992.</p><p>Zhiyi or Chih-i \'jir-'e\ (b. 538, Hunan province, China�d. 597, Mount  Tiantai, Zhejiang province) Chinese Buddhist monk who founded the  eclectic Tiantai sect. Orphaned at age 17, he studied with the Buddhist  master Huisi for seven years. He was associated with the imperial gov�  ernments of the Chen dynasty in southern China and the Sui dynasty, which  reunified China. He reconciled the various strains of Buddhism by regard�  ing all Buddhist doctrines as true and present in the mind of the enlight�  ened Buddha, who unfolded his teachings in periods to accommodate his  listeners� capacities. He considered the Lotus Sutra the highest teaching  and helped establish it as the most popular scripture in East Asia.</p><p>Zhongyong or Chung yung \'juq-'yuq\ or Doctrine of the  Mean One of four ancient Confucian texts known as the Four Books,  published together in 1190 by Zhu Xi. Its metaphysics had interested Bud�  dhists and earlier Neo-Confucianists. Zhu Xi attributes the work to Con�  fucius� grandson Zi Si, though it was actually part of Liji (�Book of  Rites�), one of the Five Classics. Zhongyong expresses an ideal of mod�  eration, rectitude, and lack of prejudice that should encompass virtually  every relationship and activity in life.</p><p>Zhou dynasty or Chou \'jo\ dynasty (1046-256 bc) Ancient Chi�  nese dynasty that gave China its historically identifying political and cul�  tural characteristics. The period before 771 bc is known as the Western  Zhou; the period from 771 bc on is called the Eastern Zhou and is further  divided into the Spring and Autumn period (770-476) and the Warring States  period (475-221). During the Zhou dynasty, iron, ox-drawn plows, cross�  bows, and horseback riding were introduced; large-scale irrigation projects  were instituted; the Chinese writing system was further developed; and the  great Chinese philosophers of antiquity, including Confucius, Mencius, and  Zhuangzi, lived and taught. Pottery and bronzework expanded on the tra�  ditions of the earlier Shang dynasty, as did work in jade and lacquer.</p><p>Zhou Enlai or Chou En-lai Vjo-'en-'llX (b. March 5, 1898, Huai�an,  Jiangsu province, China�d. Jan. 8, 1976, Beijing) Chinese communist  leader, premier from the founding of the People�s Republic of China until  his death (1949-76). Zhou became a communist during his studies abroad  in France and was an organizer for the Chinese Communist Party in Europe.  Like other communists, he worked with the Nationalists in the early 1920s  and escaped capture when Chiang Kai-shek purged his former allies in 1927.  He joined Zhu De and Mao Zedong in Jiangxi province and became political  commissar of the Red Army. In the 1930s he negotiated a tactical alliance  with the Nationalists to resist Japanese aggression. When the communists  prevailed over the Nationalists in 1949, Zhou became premier of the new  People�s Republic of China. During the Cultural Revolution, Zhou helped  restrain extremists; as the revolution waned in the early 1970s, he sought to  restore Deng Xiaoping and other moderates to power. He is credited with</p><p>arranging the historic meeting between U.S. Pres. Richard Nixon and Mao  that paved the way for U.S. recognition of the communist government.</p><p>Zhougong or Chou-kung \'jo-'guq\ (fl. 11th century bc, China)  Political figure who solidified the power of the Zhou dynasty. On the death  of his brother Wuwang, founder of the Zhou, he resisted the temptation  to seize the throne and chose instead to serve as counselor to his nephew,  the second Zhou ruler. When Zhougong stepped down after seven years,  the Zhou political and social system had been stabilized. Confucius so  admired Zhougong�s wisdom and virtue as a minister, that he proffered  him as a model for rulers of his own time to emulate.</p><p>Zhoukoudian Vjo-kod-yonX or Chou-k'ou-tien Archaeological  site some 26 mi (42 km) southwest of Beijing, China, where fossil remains  of the extinct hominin Homo erectus have been found. So-called Peking  man was identified as a new fossil human by Canadian anthropologist  Davidson Black in 1927 and variously classified as Pithecanthropus and  Sinanthropus before being assigned to H. erectus. Partial remains of about  40 individuals along with more than 100,000 artifacts have been uncov�  ered, making Zhoukoudian one of the most important H. erectus sites in  the world. Its strata date to 550,000-230,000 years ago. It was named a  World Heritage site in 1987.</p><p>Zhu De or Chu Teh Vjii -'de\ (b. Dec. 1, 1886, Yilong, Sichuan prov�  ince, China�d. July 6, 1976, Beijing) Founder of the Chinese commu�  nist force that became the People's Liberation Army. Educated at Yunnan  Military Academy, Zhu began his military career in the armies of war�  lords in southern China. He became a communist in the early 1920s but  hid his affiliation to become an officer in the Nationalist army. In 1927  he took part in the communist-led Nanchang Uprising, an event celebrated  annually in China as the birth of the People�s Liberation Army. When the  uprising was defeated, Zhu led his troops south to join Mao Zedong�s  small guerrilla forces. He became commander in chief of the communist  forces, a position he held through World War II and the civil war with the  Nationalists, not stepping down until 1954. With Mao, Zhu is credited  with elevating guerrilla warfare to a major strategic concept.</p><p>Zhu Rongji Vjii-roq-'jeXorChu Jung-chi (b. Oct. 23,1928, Changsha,  Hunan province, China) Premier of the State Council of China (1998�  2003). In the 1950s he was denounced as a rightist, and he was purged again  in the 1970s, but, once his Communist Party membership was restored, he  rose rapidly. In 1988 he became mayor of Shanghai and in 1991 a deputy  premier of the State Council. He was governor of the People�s Bank of  China (1993-95) and became director of the Institute for Economic Man�  agement at Qinghua University in 1994. He was appointed premier in  1998. In the face of the Asian economic crisis at the end of the 1990s, he  worked to drastically cut back the size of the government bureaucracy. Zhu,  whose economic policies have been both praised and criticized, stepped  down as premier in 2003 and was replaced by Wen Jiabao.</p><p>Zhu Shijie (fl. 1300, China) Chinese mathematician who stood at the  pinnacle of traditional Chinese mathematics. Zhu is known for having  unified the southern and northern Chinese mathematical traditions. His  fame rests on two publications, Suanxue qimeng (1299; �Introduction to  Mathematical Science�) and Siyuan yujian (1303; �Precious Mirror of  Four Elements�). The former is an introductory mathematics textbook;  following the southern Chinese tradition, it presents many rules and prob�  lems in the form of verses to facilitate their memorization. It played a  central role in the development of the xvasan (�Japanese calculation�) tra�  dition. �Precious Mirror� corresponds to the final stage in the generali�  zation of the northern Chinese technique of tian yuan (�method of the  celestial unknown�), a kind of algebraic computation performed with  counting rods to solve problems.</p><p>Zhu Xi or Chu Hsi \'ju-'she\ (b. Oct. 18, 1130, Yu-hsi, Fukien prov�  ince, China�d. April 23, 1200, China) Chinese philosopher and propo�  nent of Neo-Confucianism. The son of a minor government official, he was  educated in the Confucian tradition and entered government service. Inter�  ested in history, he revised Sima Guang�s famous history so that it would  illustrate moral principles in government. In 1189 he began a commen�  tary on the Daxue; he continued working on the Daxue all his life. Philo�  sophically, his thought incorporated the ideas of Cheng Hao and Cheng  Yi, Zhou Dunyi (1017-1073), and Zhang Zai, whose works he compiled.  His commentaries on the Four Books, notably on the Lunyu ( Analects ) of  Confucius and on Mencius (both 1177), were enormously influential. His  philosophy emphasized logic, consistency, observance of classical author�  ity, and the value of inquiry.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>ZhuYuanzhang &#x25BA; Zimbabwe I 2109</p><p>Zhu Yuanzhang See Hongwu emperor</p><p>Zhuangzi or Chuang-tzu Vjwaq-'dziA (b. c. 369, Meng, China�d.  286 bce) Most significant early Chinese interpreter of Daoism and the pur�  ported author of the Daoist classic that bears his name. A minor official  and a contemporary of Mencius, he drew on the sayings of Laozi but took  a broader perspective. He taught that enlightenment comes from the real�  ization that everything is one, the DAO, but that the dao has no limitations  or demarcations and whatever can be known or said of the dao is not the  dao. He held that things should be allowed to follow their own course and  that no situation should be valued over any other.</p><p>Zhuge Liang or Chu-ko Liang Vju-'go-le-'aqX (b. ad 181, Yangdu,  Shandong province, China�d. August 234, Wuzhangyuan, Shaanxi prov�  ince, China) Celebrated adviser to Liu Bei, founder of the Shu-Han  dynasty of the Six Dynasties period. Liu was so impressed with Zhuge that  on his deathbed he urged Zhuge to take the throne himself if his own son  proved incapable. A genius in mechanics and mathematics, Zhuge is cred�  ited with inventing a bow for shooting several arrows at once and with  perfecting the Eight Dispositions, a series of military tactics. Supernatu�  ral powers were often ascribed to him, and he is a favourite character in  Chinese plays and stories, notably Sanguozhi yanyi {Romance of the Three  Kingdoms). In 1724 he was made a Confucian saint.</p><p>Zhukov \'zhii- I k6f\ / Georgy (Konstantinovich) (b. Dec. 1, 1896,  Kaluga province, Russia�d. June 18, 1974, Moscow, Russia, U.S.S.R.)  Soviet army commander in World War II. He joined the Red Army in the  Russian Civil War and rose to become head of Soviet forces in Manchuria  (1938-39). In World War II he was chief of staff of the Red Army and  organized the defense of Leningrad and Moscow (1941). He directed the  offensive that broke the siege in the Battle of Stalingrad (1943) and was  named a marshal of the Soviet Union. After helping win the Battle of  Kursk, he directed the Soviet offensive through Belorussia (now Belarus)  and commanded the final assault on Berlin (1945). After the war Zhu�  kov�s great popularity caused him to be regarded as a potential threat by  Joseph Staun, who assigned him to obscure regional commands. After Sta�  lin�s death he was appointed minister of defense (1955) and attempted to  make the army more autonomous, but opposition from Nikita Khrushchev  caused his dismissal in 1957. He remained in relative obscurity until  Khrushchev fell from power in 1964, and he was subsequently awarded  the Order of Lenin (1966).</p><p>Zia (ur-Rahman), Begum Khaleda orig. Khaleda Majum-</p><p>dar (b. Aug. 15, 1945, Dinajpur district, India) Politician who served as  prime minister of Bangladesh.

Her husband became president of Bangladesh in 1977, and after his assas�  sination in 1981 she became politically active. In 1984 she assumed the  leadership of the Bangladesh Nationalist Party. Zia was arrested repeat�  edly during the dictatorship of Hossain Mohammad Ershad in the 1980s,  but in 1991 she led the opposition to victory and became prime minister.  Her overwhelming reelection victory in February 1996 was tainted by an  opposition-led boycott of the voting, and, after a wave of strikes and pro�  tests, she resigned the following month. In 2001 Zia was again elected  prime minister.</p><p>Zia-ul-Haq Vze-s-ol-'hakX, Mohammad (b. Aug. 12, 1924, Jullun-  dur, Punjab, India�d. Aug. 17, 1988, near Bahawalpur, Pak.) President  of Pakistan (1978-88). He served with the British in Southeast Asia at the  end of World War II; after Pakistan�s independence, he held various staff  and command appointments for 19 years. He became a major general in  1972 and army chief of staff in 1976. The following year he seized power  from Zulfikar Au Bhutto, and in 1978 he assumed the presidency. After  having the popular Bhutto executed in 1979, he tightened his grip on the  government, suspending political parties and declaring martial law, and  he worked for the Islamization of Pakistan�s political and cultural life.

He worked as a publicist for Sandow the strongman before turning to the�  atrical management in 1896. His press releases promoting the French  beauty Anna Held set a pattern of star-making publicity. In 1907 in New  York City he produced the first of his Ziegfeld Follies, revues that com�  bined seminudity, pageantry, and comedy in a formula that he repeated  successfully for 23 years. Under the slogan �Glorifying the American</p><p>Girl,� he made the revue an extravagant spectacle and developed stars  such as Will Rogers and Fanny Brice.

He held academic  appointments at the Universities of Frankfurt am Main, Heidelberg, and  Halle, and in 1943 he became director of the Kaiser Wilhelm (later Max  Planck) Institute. He was the first to explain the reactions involved in the  synthesis of rubber (c. 1928). His most important work, in the 1950s, led  to the discovery that certain catalysts permitted the fast polymerization of  ethylene at atmospheric pressure to a linear polymer of high molecular  weight having valuable plastic properties. His work formed the basis of  nearly all later developments in the production of long-chain polymers of  hydrocarbons from such olefins as ethylene and butadiene; the resulting  products came into widespread use as plastics, fibres, rubbers, and films.  He shared a 1963 Nobel Prize with Giulio Natta (1903-79).</p><p>ziggurat Vzi-g9-,rat\ Pyramidal, stepped temple tower characteristic of  the major cities of Mesopotamia between 2200 and 500 bc.

Religions: Christianity  (other [mostly independent] Christians,  Protestant, Roman Catholic), traditional  beliefs. Currency: Zimbabwe dollar. A broad ridge running southwest-  northeast, reaching elevations of 4,000-5,000 ft (1,200-1,500 m), domi�  nates Zimbabwe�s landscape. The Zambezi River forms the country�s  northwestern boundary and contains Victoria Falls as well as the Kariba  Dam (completed 1959); Lake Kariba, created by the dam, covers some  2,000 sq mi (5,200 sq km). The Limpofo and Save river basins are in the  southeast. Agricultural products, livestock, and mineral reserves, including  gold, are all economically important.

The first Bantu-speaking peoples reached it during the 5th� 1 Oth cen�  turies ad, driving the San inhabitants into the desert. A second migration of  Bantu speakers began c. 1830. During that period the British and Afrikan�  ers moved up from the south, and the area came under the administration of  the British South Africa Company (1889-1923). Called Southern Rhodesia  (1911-64), it became a self-governing British colony in 1923. The colony  united in 1953 with Nyasaland (Malawi) and Northern Rhodesia (Zambia)  to form the Central African Federation of Rhodesia and Nyasaland. The  federation dissolved in 1963, and Southern Rhodesia reverted to its former  colonial status. In 1965 it issued a unilateral declaration of independence  considered illegal by the British government, which led to economic sanc�  tions against it. The country, which proclaimed itself a republic in 1970,  called itself Rhodesia from 1964 to 1979. In 1979 it instituted limited  majority rule and changed its name to Zimbabwe Rhodesia. It was granted  independence by Britain in 1980 and became Zimbabwe. A multiparty sys�  tem was established in 1990.

With  Germany�s decision to resume unrestricted submarine warfare, he planned  to reduce the possible U.S. intervention in Europe by embroiling it in war  with Mexico. On Jan. 16, 1917, he sent a coded telegram to the German  ambassador in Mexico, proposing a German-Mexican alliance that would  allow Mexico to �reconquer her lost territory in Texas, New Mexico, and  Arizona.� It was intercepted and decoded by British naval intelligence,  then published in the U.S. on March 1, causing public outrage. The �Zim�  mermann telegram� became a key factor in the U.S. declaration of war  against Germany on April 6.

Born to lower middle-class Jewish parents, he received  no formal education, but during travels abroad in 1902-05 he attended  lectures on law at Bern University. An early activist with the Bolsheviks  (1903), he became Vladimir Lenin�s close collaborator in exile (1909-17)  and in the Russian Revolution of 1917, helping win public support for the  Bolshevik regime. By 1921 he was head of the Petrograd (St. Petersburg)  soviet and a member of the Politburo. He was chairman of the Comin�  tern (1919-26) and helped Joseph Stalin oust Leon Trotsky. He was removed  from power by Stalin in 1926. Although he was subsequently readmitted  to the party, he never recovered his former prestige and was expelled again  on two other occasions (1932 and 1934). In 1935 he was arrested for con�  spiracy and sentenced to prison.

In the face of persistent anti-  Semitism, Theodor Herzl advocated a Jewish state in Palestine. He held the  first Zionist Congress in Basel in 1897. After World War I the movement  picked up momentum with the issuing of the Balfour Declaration. The Jew�  ish population in Palestine increased from 90,000 in 1914 to 238,000 in  1933. The Arab population resisted Zionism, and the British tried unsuc�  cessfully to reconcile Jewish and Arab demands. Zionism achieved its goal  with the creation of Israel in 1948.

Their common features include: origination from a mandate received by  a prophet in a dream or vision; a chieflike leader who is succeeded by his  son and who is occasionally regarded as a Messiah; healing through con�  fession, repeated baptism, purification rites, and exorcism; revelation and  power from the Holy Spirit through prophetic utterances and pentecostal  phenomena; Africanized worship characterized by singing, dancing, clap�  ping, and drumming; and repudiation of traditional magic, medicines,  divination, and ancestor cults, though these are often replaced with Chris�  tianized equivalents.</p><p>zip code System of postal-zone codes (zip stands for �zone improve�  ment plan�) introduced in the U.S. in 1963 to improve mail delivery and  exploit electronic reading and sorting capabilities. The original code,  which corresponds to the postal codes used in most countries in the world,  consists of five numbers. The first three identify the state and portion of  the state, the last two a specific post office or zone. In 1983 a nine-digit  code (created by adding a hyphen and four digits) was introduced to fur�  ther speed delivery; the first two added digits specify a particular �sec�  tor,� the last two an even smaller �segment� (e.g., one side of a city block,  or a single floor in a large building).</p><p>zipper Device for binding the edges of an opening, as on a garment or a  bag. A zipper consists of two strips of material with metal or plastic teeth  along the edges, and a sliding piece that interlocks the teeth when moved in  one direction and separates them again when moved in the opposite direc�  tion. The idea of a slide fastener was first exhibited by Whitcomb L. Judson  (died 1909) at the World�s Columbian Exposition of 1893. The modern  form of the zipper began to appear on clothing in the late 1920s.</p><p>zircon Silicate mineral, zirconium silicate, ZrSi0 4 , the principal source of  zirconium. Zircon is widespread as  an accessory mineral in acid igneous  rocks; it also occurs in metamorphic  rocks and, fairly often, in detrital  deposits. It occurs in beach sands in  many parts of the world, particularly  Australia, India, Brazil, and Florida,  and is a common heavy mineral in  sedimentary rocks. Gem varieties  occur in stream gravels and detrital  deposits, particularly in Indochina  and Sri Lanka, but also in Myanmar,</p><p>Australia, and New Zealand. Zircon  forms an important part of the syenite  of southern Norway and occurs in  large crystals in Quebec.</p><p>zirconium Metallic chemical ele�  ment, one of the transition elements,  chemical symbol Zr, atomic number 40. The metal is hard and brittle when  impure, soft and ductile when highly purified. It is relatively abundant,  occurring as zircon (also marketed as a natural gemstone) and baddeleyite.  Highly transparent to neutrons, zirconium became important in the 1940s  in nuclear energy applications such as fuel cladding. Other uses are in  alloys, fireworks, and flashbulbs and as a scavenger for oxygen and other  gases. Its compounds, in most of which it has valence 4, are important  industrial materials. Zirconia (the oxide) is used in piezoelectric crystals  (see piezoelectricity), high-frequency induction coils, coloured glazes and  glasses, and heat-resistant fibres; zirconium carbonate is employed in  preparations to treat the rash of poison ivy.</p><p>zither Plucked or struck stringed instrument with a shallow soundbox.

He held ministerial  posts in the government (1920-24) and was elected head of the Albanian  republic in 1925. Proclaimed king in 1928, he pursued a policy of close  collaboration with Italy. Unable to resist Benito Mussolini�s increasing con�  trol of the country�s finances and army, he was forced into exile when Italy  invaded and made Albania a protectorate (1939). After World War II Alba�  nia became a communist republic, and Zog formally abdicated in 1946.</p><p>Zola Vzo-lo,\ French \zo-'la\, Emile (-Edouard-Charles-  Antoine) (b. April 2, 1840, Paris, France�d. Sept. 28, 1902, Paris)  French novelist and critic. Raised in straitened circumstances, Zola worked  at a Paris publishing house for several years during the 1860s while estab�  lishing himself as a writer. In the gruesome novel Therese Raquin (1867),  he put his �scientific� theories of the determination of character by heredity  and environment into practice for the first time. These ideas established  him as the founder of naturalism in literature. In 1870 he began the ambi�  tious project for which he is best known, the Rougon-Macquart Cycle  (1871-93), a sequence of 20 novels documenting French life through the  lives of the violent Rougon family and the passive Macquarts. It includes  LAssommoir (1877), a study of alcoholism that is among his most suc�  cessful and popular novels; Nana (1880); Germinal (1885), his master�  piece; and La Bete humaine (1890). Among his other works are two shorter  novel cycles and treatises explaining his theories on art, including The  Experimental Novel (1880). He is also notable for his involvement in the  Alfred Dreyfus affair, especially for his open letter, �J�accuse� (1898),  denouncing the French army general staff. He died under suspicious cir�  cumstances, overcome by carbon-monoxide fumes in his sleep.</p><p>Zollverein Vtsol-ver-.InN (German: �Customs Union�) Free-trade area  throughout much of Germany established in 1834 under Prussian leader�  ship.

By 1834 other German  states had joined, for a total of 18 members; more joined in subsequent  years. The Zollverein represented an important step in German unifica�  tion.

In zone refining, the most  important of the zone-melting techniques, a solid is refined by multiple  molten zones being passed through it in one direction. Each zone carries  a fraction of the impurities to the end of the solid charge, thereby puri�  fying the remainder. Zone refining is particularly important as a method  of purifying crystals, especially for use in semiconductor devices.</p><p>zone of avoidance See avoidance, zone of</p><p>zoning Legislative method of controlling land use by regulating consid�  erations such as the type of buildings that may be erected and population  density. German and Swedish cities first applied zoning regulations in the  late 19th century to address the problems of urban congestion and building  height. The earliest U.S. zoning ordinances, which date from the beginning  of the 20th century, were motivated by the need to regulate the location of  commercial and industrial activities. In 1916 New York City adopted the  first comprehensive zoning law; it and other early regulations were  designed to protect property values and preserve light and air. Modern zon�</p><p>ing regulations divide land use into three types: residential, commercial,  and industrial. Within each designation, more specific aspects of develop�  ment (e.g., building proximity, height, and type) are also determined. Zon�  ing is often used to maintain the distinctive character of a town or city; an  adverse consequence of such zoning is economic segregation. The Supreme  Court of the United States ruled against such laws in 1977 when it declared  the zoning regulations of one Chicago suburb discriminatory.</p><p>zoo or zoological garden Place where wild and sometimes domes�  ticated animals are exhibited in captivity. Aquatic zoological gardens are  called aquariums. The first zoos were perhaps associated with domesti�  cation. Pigeons were kept in captivity as early as 4500 bc; other animals  (e.g., elephants and antelopes) have also been kept in captivity since  antiquity. Animal collections were kept by Charlemagne and other Euro�  pean monarchs. Hernan Cortes described a zoo in Mexico (1519) so large  that it required a staff of 300. Modern zookeeping started in 1752 with  the founding of the Imperial Menagerie at Vienna�s Schonbrunn Palace.  Open-range zoos were first established in the early 1930s, some so large  that visitors drive through in cars, as on an African safari. There are now  more than 1,000 animal collections open to the public throughout the  world (e.g., in the U.S., the Bronx Zoo and San Diego Zoo).</p><p>zoology Branch of biology concerned with members of the animal king�  dom and with animal life in general. The science originated in the works of  Hippocrates, Aristotle, and Pliny. The contributions of individuals such as  William Harvey (the circulation of blood), Carolus Linnaeus (system of  nomenclature), Georges-Louis de Buffon (natural history), Georges Cuvier  (comparative anatomy), and Claude Bernard (homeostasis) greatly  advanced the field. The 1859 publication of Charles Darwin�s On the Origin  of Species by Means of Natural Selection was a major turning point. Since  that time, the study of genetics has become essential in zoological studies.</p><p>zooplankton \ l zo-9- , plaqk-t3n\ Small floating or weakly swimming  animals that drift with water currents and, with phytoplankton, make up  the planktonic food supply on which almost all oceanic organisms ulti�  mately depend (see plankton).

Permanent plankton (holoplankton), such as protozoans and copepods,  spend their lives as plankton. Temporary plankton (meroplankton), such  as young starfish, clams, worms, and other bottom-dwelling animals, live  and feed as plankton until they become adults.</p><p>Zorn, John (b.

He was a priest in his  tribal religion, with which he eventually became disillusioned. Having  received a vision, he began teaching that Ahura Mazda was the highest  god and alone was worthy of worship, a concept that went against the  polytheism of Iranian religion. He forbade the orgiastic rites that accom�  panied animal sacrifice, common in his time, but preserved the ancient  cult of fire worship. After converting a king called Vishtaspa to his teach�  ings, Zoroaster remained at the royal court. He became the subject of leg�  ends and a model for various occupations.</p><p>Zoroastrianism and Parsiism Ancient religion that originated in  Iran based on the teachings of Zoroaster. Founded in the 6th century bce,  it influenced the monotheistic religions Judaism, Christianity, and Islam.  It rejects polytheism, accepting only one supreme God, Ahura Mazda. In  early Zoroastrianism, the struggle between good and evil was seen as an  eternal rivalry between Ahura Mazda�s twin sons, Spenta Mainyu (good)  and Angra Mainyu (evil). Later Zoroastrian cosmology made the rivalry  between Ahura Mazda himself (by then called Ormizd) and Angra Mainyu  (Ahriman). This later cosmology identifies four periods of history; the last  began with the birth of Zoroaster. Zoroastrian practice includes an initia�  tion ceremony and various rituals of purification intended to ward off evil  spirits. Fire worship, a carryover from an earlier religion, survives in the  sacred fire that must be kept burning continually and be fed at least five  times a day. The chief ceremony involves a sacrifice of haoma, a sacred  liquor, accompanied by recitation of large parts of the Avesta, the primary</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>Zorrilla &#x25BA; Zurbaran I 2113</p><p>scripture. Zoroastrianism enjoyed status as an official religion at various  times before the advent of Islam, but Zoroastrians were persecuted in the  8th-10th centuries, and some left Iran to settle in India. By the 19th cen�  tury these Indian Zoroastrians, or Parsis, were noted for their wealth and  education. The small group of Zoroastrians remaining in Iran are known  as the Gabars.</p><p>Zorrilla \thor-'rel-ya\ (y Moral), Jose (b. Feb. 21, 1817, Valladolid,  Spain�d. Jan. 23, 1893, Madrid) Spanish poet and dramatist. Zorrilla first  gained notice in 1837 with his recitation of an elegy at the funeral of the  satirist Mariano Jose de Larra. The major figure of the nationalist wing  of the Spanish Romantic movement, he made his name with verse ley-  endas (�legends�) about remote times and places, notably in Cantos del  trovador (1841). His greatest success was Don Juan Tenorio (1844), the  most popular play of 19th-century Spain. His works are considered quint-  essentially Spanish in style and tone. In 1889 he was crowned the national  poet.</p><p>Zu Chongzhi (b. 429, Jiankang, China�d. 500, China) Chinese  astronomer, mathematician, and engineer. About 462 he proposed a new  calendar system that would provide a more precise number of lunations  per year and take into consideration the precession of the equinoxes. His  Darning calendar was finally adopted in 510 through the efforts of his  son, Zu Gengzhi. Li Chunfeng called Zu Chongzhi the best mathematician  ever and gave him credit for three approximations of n: 22 /i, 355 /ii3, and the  interval 3.1415926 &lt;n&lt; 3.1415927; the third result remained the best in  the world until improved by the Arab mathematician al-Kashi (fl. c. 1400).  He also worked on the mathematical theory of music and metrology, and  he constructed several devices, such as a semilegendary �south-pointing  carriage.� The carriage was topped by a symbolic figure that, once prop�  erly aligned, would always point to the south.</p><p>Zu Gengzhi also known as Zu Xuan (b. c. 480, Jiankang, China�d.  c. 525, China) Chinese government official, mathematician, astronomer,  and son of Zu Cfiongzhi. Beginning in 504, he actively advocated his  father�s Darning calendar and finally succeeded in getting it officially  adopted in 510. His astronomical observations with gnomons allowed him  to measure the angular distance between Polaris and the celestial north  pole. A mathematical fragment of his was appended by Li Chunfeng to the  commentary on Jiuzhang suanshu (.Nine Chapters on the Mathematical  Procedures), a Chinese classic probably compiled in the 1st century ad.  Fragments of his writings are also found in the astronomical chapter of  Suishu (�History of the Sui Dynasty�).

He codified the theory of Mannerism in The Idea of  Painters, Sculptors, and Architects (1607) and in a series of frescoes in  his own house in Rome. In England in 1575 he drew or painted portraits  of Elizabeth I and the earl of Leicester. He also painted the dome of the  cathedral of Florence (1574), a large work in the Doges� Palace in Ven�  ice (1582), and much work for El Escorial in Spain (1585-88).

Frisian peoples inhabited the  sand flats from c. ad 400 and built the first sea works, considered engi�  neering marvels, to stem rising sea levels. The control of water levels  within the dikes developed into the reclamation of lowlands (polders)  from the water. Between 1927 and 1932 a dam 19 mi (30 km) long was  built across the Zuiderzee, separating it into the Waddenzee and the Ijs�  selmeer.

Extending southeast from the city of ZOrich, it lies at an alti�  tude of 1,332 ft (406 m) and has an area of about 34 sq mi (88 sq km).  It is 18 mi (29 km) long and has a maximum depth of 469 ft (143 m).  The Linth River flows into it and emerges as the Limmat.</p><p>Zuse Vtsu-Z9\, Konrad (b. June 22, 1910, Berlin, Ger.�d. Dec. 18,  1995, Hiinfeld) German engineer. In 1941 he constructed the first fully  operational program-controlled electromechanical binary calculating  machine, or digital computer, called the Z3. The machine predated Howard  H. Aiken�s Harvard Mark I but was destroyed by bombing during World  War II. In 1945 he designed Plankalkiil, one of the first attempts at a high-  level programming language, which later influenced the development of  ALGOL.</p><p>Zweig \'tsv!k\, Arnold (b. Nov. 10, 1887, Glogau, Silesia, Ger.�d.  Nov. 26, 1968, East Berlin, E.Ger.) German writer. Zweig, who was Jew�  ish, was exiled from Germany by the Nazis in 1933. He lived as an emi�  gre in Palestine until 1948, when he moved to East Germany. He is best  known for the novel The Case of Sergeant Grischa (1927), which depicts  the German army in World War I through a Russian prisoner�s tragic  encounter with the Prussian military bureaucracy. Later works, including  Education Before Verdun (1935) and The Crowning of a King (1937), fol�  low the fortunes of characters he introduced in Sergeant Grischa.</p><p>Zweig, Stefan (b. Nov. 28, 1881, Vienna, Austro-Hungarian  Empire�d. Feb. 22, 1942, Petropolis, near Rio de Janeiro, Braz.) Aus�  trian writer. He was deeply influenced by Sigmund Freud, whose theories  on psychology informed Zweig�s analyses of historical figures and his  subtle portrayal of fictional characters. His essays include studies of Hon�  or! de Balzac, Charles Dickens, and Fyodor Dostoyevsky, in Three Masters  (1920); and Friedrich Holderun, Heinrich Kleist, and Friedrich Nietzsche, in  Master Builders (1925). He achieved popularity with The Tide of Fortune  (1928), five historical portraits in miniature. He also wrote biographies,  poetry, short stories, dramas, and a novel. Driven into exile by the Nazis  in 1934, Zweig and his second wife went to England and then Brazil,  where, lonely and disillusioned, they committed suicide.</p><p>Zwicky Vtsvik-e\, Fritz (b. Feb. 14, 1898, Varna, Bulg.�d. Feb. 8,  1974, Pasadena, Calif., U.S.) Swiss astronomer and physicist. He received  his Ph.D. from the Swiss Federal Institute of Technology and moved to  the U.S. in 1925 to work at Caltech, where he remained until 1972. In  1934, with Walter Baade (1893-1960), he proposed that supernovas are a  class of stellar explosions completely different from novas. He conducted  an extensive search of neighbouring galaxies for supernovas and discov�  ered 18; only about 12 had been recorded previously in the entire history  of astronomy. In the years 1943-46, with Theodore von Karman and oth�  ers, he helped develop early jet-propulsion systems.</p><p>Zwilich \'zwi-lik\, Ellen Taaffe (b. April 30, 1939, Miami, Fla., U.S.)  U.S. composer. She was trained as a violinist, studying with Ivan</p><p>Galamian (1903-81). She studied composition with Elliott Carter and  Roger Sessions at Juilliard. Her straightforward and expressive music won  wide recognition; her Symphony No. 1 (1983) was the first composition  by a woman to win a Pulitzer Prize. Her orchestral work Symbolon pre�  miered in Russia in 1988. She is noted for writing music that is both sub�  stantive and accessible.</p><p>Zwinger Vtsviq-orX Rococo-style building complex (1709-32), on the  southern bank of the Elbe in Dresden, Germany, designed by Matthaus  Daniel Poppelmann (1662-1736). Originally planned as the forecourt for  a castle, it is considered one of the finest works of its style in the world.  It comprises one- and two-story buildings surrounding an immense square  court. Its festive air is accented by bold, richly sculpted and ornamented  facades and gates and by dramatic contrasts between its low arcades and  high pavilions.</p><p>Zwingli \'zwiq-le,\ German Vtsvir  Wildhaus in the Toggenburg, Sankt  Gallen, Switz.�d. Oct. 11, 1531,  near Kappel) Major reformer in the  Protestant Reformation in Switzer�  land. Educated in Vienna and Basel,  he was ordained a priest in 1506. An  admirer of Erasmus, he began preach�  ing reformist ideas in Zurich in 1518,  shortly after Martin Luther made his  break with the church in Rome, and  became increasingly active in chal�  lenging the ritualism, decadence, and  hierarchy of the Roman Catholic  church. The main contentions of his  67 Articles (1523) were adopted by  most priests in Zurich. As his move�  ment spread, he rejected a number of  the basic teachings of the church,  declaring that Jesus alone is head of  the church, that the mass is an affront  to Christ, and that there is no bibli�  cal foundation for the intercession of  the dead or for purgatory. He also  rejected the notions of priestly celibacy, and his teachings on the sacra�  ment of communion brought him into conflict with both Luther and the  Catholic church. He was killed in a battle between Protestants and Catho�  lics while serving as an army chaplain.</p><p>Zworykin \'zvor y -kyin,\ English Vzwor-i-kanN, Vladimir (Kosma)  (b. July 30, 1889, Murom, Russia�d. July 29, 1982, Princeton, N.J., U.S.)  Russian-born U.S. electronic engineer and inventor. He immigrated to the  U.S. in 1919. While with Westinghouse Electric Corp. (1920-29), he filed  patent applications for his inventions of the iconoscope (a TV transmis�  sion tube, 1923) and the kinescope (TV receiver, 1924), which formed the  first all-electronic TV system. He patented a colour TV system in 1928.  In 1929 he became director of electronic research at RCA. His electron  image tube, sensitive to infrared light, was the basis for devices first used  in World War II for seeing in the dark.</p><p>zydeco Vzl-d9-,k6\ Form of dance music from southwestern Louisiana,  U.S., with roots in French, African American, and Afro-Caribbean styles.  Similar to the music of the Cajuns (displaced French Canadians who  settled in Louisiana), zydeco was created by the Creoles (those of Afri�  can heritage in Louisianan French culture). Its name is thought to come  from a modified pronunciation of the French phrase les haricots (�the  beans�) heard in a popular song. The music usually features guitar, accor�  dion, fiddle (violin), and washboard played to a driving beat, but it may  also include electric guitar, electric bass, saxophone, and keyboards. It  became widely popular in the 1980s through the performances of Clifton  Chenier, Queen Ida, Buckwheat Zydeco, Boozoo Chavis, and others.</p><p>zymogen VzI-mo-jonV or proenzyme Any of a class of proteins that  are secreted by cells and are inactive precursors of enzymes. Transforma�  tion into active enzymes occurs as one or more peptide bonds in the  zymogen are cleaved. Examples include trypsinogen and chymotrypsino-  gen, secreted by the pancreas and converted by proteolysis in the small  intestine into the active enzymes trypsin and chymotrypsin; and numerous  coagulation factors.</p><p>)-le\, Huldrych (b.

In some cases, areal characteristics have been estimated  from descriptions (or drawings) of first contact by the earliest Europeans. In other cases, where there was little European contact or where there  is scant information about native populations (as, for example, the populations of Inner Asia), skin color was estimated from surrounding  populations and geographic and climatological information. On a map of this scale, it is difficult to give more than a representation of current  understanding. It must also be noted that many populations, even before the modern era, were quite heterogeneous in skin color, and this  heterogeneity is difficult to depict accurately on any scale. In areas of the world where the indigenous population was sparse and widely  scattered (such as Australia), the map's color density can be misleading. Further, some populations, such as the Tasmanians (who are virtually  extinct) and Maoris (who have been widely mixed with Europeans), present only a few examples of "unmixed" individuals in historical records.</p><p>� 2006 Encyclopedia Britannica, Inc.</p><p>Plate 14 I World Heritage sites</p><p>On this plate and the  adjoining one is a  sampling of official  World Heritage sites,  as designated by the  United Nations  Educational, Scientific  and Cultural  Organization  (UNESCO).</p><p>v -A iffiA fa. * j</p><p>This page (clockwise):</p><p>Rose window, Notre-Dame  de Paris, 13th century;  terra-cotta warriors from  the 3rd-century bc Qin  tomb of Emperor  Shihuangdi, near Xi'an,  China; elephants and  acacia trees on the plain  near Kilimanjaro, Tanzania;  abundant and colourful sea  life on the Great Barrier  Reef, off the northeast  coast of Australia;  cruciform Coptic church  carved from solid rock, c.  13th century, Lalibela,  Ethiopia.</p><p>World Heritage sites I Plate 15</p><p>This page (clockwise from top  left) the pyramid El Castillo in the  Mayan city of Chichen Itza,  founded 6th century ad, Yucatan,  Mexico; Temple of the Golden  Pavilion, Kydto, Japan, 14th  century (rebuilt, 1955); the Taj  Mahal, built mainly 1632-43 by  Shah Jahan as a mausoleum for  his wife Mumtaz Mahal, Agra,  India; giant tortoise on Isabela  Island, Galapagos Islands, off  the coast of Ecuador; Anasazi  cliff dwellings, c. 1200, Mesa  Verde National Park, Colorado;  detail of a painted ceiling in Rila  Monastery, southwestern  Bulgaria.</p><p>Plate 15: Photographs (clockwise from top left) � Corbis; Kaz Mori�The Image Bank/Getty Images; Gavin Hellier�Robert Harding World Imagery/Getty Images;  Craig Lovell/Corbis; Walter Rawlings �Robert Harding World Imagery/Getty Images; � Corbis.</p><p>� 2006 Encyclopaedia Britannica, Inc.</p><p>� 2006 Encyclopsedia Britannica, Inc.</p><p>VIONDAY</p><p>INTERNATIONAL DATE LINE</p><p>SUNDAY</p><p>J f</p><p>GREENWICH MERIDIAN</p><p>sauoz aiujj. |ouo; 4 DUJ 94 U| | 91 940 ^</p><p>Britanrrica</p><p>CONCISE</p><p>ENCYCLOPEDIA</p><p>From the editors of the Encyclopedia Britannica comes the  completely revised and expanded edition of the popular  Britannka Concise Encyclopedia</p><p>llp-to-date, with the latest developments in technology and  world affairs</p><p>Nearfy 28,000 entries prepared by the editors of the  Encyclopedia Britannka</p><p>More than 2,000 photographs, maps, flags, tables, and  drawings</p><p>Comprehensive coverage of Geography, History, Science,  Business, Politics, People, Literature and the Arts, Popular  Culture, and more</p><p>Easy-to-use A-Z format</p><p>Britannica's most popular publication worldwide - translated  into 13 languages</p><p>[ N C Y CL O r 4.
